Virtual machines are for the most part not used inside of high-energy physics (HEP) environments. Even though they provide a high degree of isolation, the performance overhead they introduce is too great for them to be used. With the rising number of container technologies and their increasing separation capabilities, HEP-environments are evaluating if they could utilize the technology. The container images are small and self-contained which allows them to be easily distributed throughout the global environment. They also offer a near native performance while at the same time aproviding an often acceptable level of isolation. Only the needed services and libraries are packed into an image and executed directly by the host kernel. This work compared the performance impact of the three container technologies Docker, rkt and Singularity. The host kernel was additionally hardened with grsecurity and PaX to strengthen its security and make an exploitation from inside a container harder. The execution time of a physics simulation was used as a benchmark. The results show that the different container technologies have a different impact on the performance. The performance loss on a stock kernel is small; in some cases they were even faster than no container. Docker showed overall the best performance on a stock kernel. The difference on a hardened kernel was bigger than on a stock kernel, but in favor of the container technologies. rkt showed performed in almost all cases better than all the others.
Solenogastres (Aplacophora) is a small clade of marine, shell-less worm-molluscs with close to 300 valid species. Their distribution ranges across all oceans, and whereas the vast majority of species has been collected and described from the continental shelf and slope, only few species are known from depths below 4,000 m. Following traditional taxonomy, identification of specimens to species level is complex and time-consuming and requires detailed investigations of morphology and anatomy—often resulting in the exclusion of the clade in biodiversity or biogeographic studies. During the KuramBio expedition (Kuril-Kamchatka Biodiversity Studies) to the abyssal plain of the Northwest Pacific and the Kuril-Kamchatka Trench, 33 solenogaster specimens were sampled from 4,830 m to 5,397 m. Within this study we present an efficient workflow to address solenogaster diversity, even when confronted with a high degree of singletons and minute body sizes, hampering the use of single individuals for multiple morphological and molecular approaches. We combine analyses of external characters and scleritome with molecular barcoding based on a self-designed solenogaster specific set of mitochondrial primers. Overall we were able to delineate at least 19 solenogaster lineages and identify 15 species to family level and beyond. Based on our approach we identified three key lineages from the two regionally most species-rich families (Acanthomeniidae and Pruvotinidae) for deeper taxonomic investigations and describe the novel abyssal species Amboherpia abyssokurilensis sp. nov. (Cavibelonia, Acanthomeniidae) using microanatomical 3D-reconstructions. Our study more than doubles the previous records of solenogaster species from the Northwest Pacific and its marginal seas. Almost all lineages are reported for the first time from the region of the (Northwest) Pacific, vastly expanding distribution ranges of the respective clades. Moreover it doubles the number of Solenogastres collected from abyssal depths on a global scale and underlines the lack of exploratory α-diversity work in the abyssal zone for reliable species estimates in marine biodiversity.
The Global Irrigation Model (GIM) is used within the framework of the global hydrological model WaterGAP to calculate monthly irrigation crop water use. Results on a 0.5 degrees grid include, consumption (ICU) and, via division by irrigation efficiencies, water withdrawal (IWU). The model distinguishes up to two cropping periods of rice and non-rice crops, each grown for 150 days, using a grid of area equipped for irrigation (AEI). Historical development of AEI and fraction of area actually irrigated (AAI) was previously considered via scaling of cell-specific results with country-specific factors for each year. In this study, GIM was adapted to use the new Historical Irrigation Data set (HID) with cell-specific AEI for 14 time slices between 1900 and 2005. AEI grids were temporally interpolated, and using the optional grid of AAI/AEI, results for years 1901-2014 were generated (runs "HID-ACT"). Thus, new installation or abandonment of irrigation infrastructure in new grid cells can be represented in a spatially explicit manner. For evaluated years 1910, 1960, 1995, and 2005, ICU from HID-ACT was superior to country-specific scaled results (run "HID-ACTHIST") in representing historical development of the spatial pattern. Compared to US state-level reference data, spatial patterns were better, while country totals were not always better. For calculating the cropping periods, 30-years climate means are needed, the choice of which is relevant. Four chosen periods before 1981-2010 all resulted in considerable, pertaining changes of ICU spatial pattern, and various percent changes in country totals. This might be because of already present climate change.

Last week’s printed edition of Focus had a piece about how Germany’s politicians are using social media. It made the dubious claim that 61% of Green top candidate Katrin Göring-Eckardt’s Twitter followers could have been bought.
Let’s actually instead try to get to grips with what is going on here, and try to draw some conclusions. ...
Alternância dativa sob a perspectiva da gramática de construções : uma análise do verbo senden
(2017)
Este trabalho apresenta uma análise da alternância dativa do verbo senden da língua alemã. Os pressupostos teóricos da Gramática de Construções postulados por GOLDBERG (1995) no que concerne aos bitransitivos e suas paráfrases preposicionais e a abordagem da sensitividade ao núcleo verbal de RAPPAPORT HOVAV E LEVIN (2008) são comparados e utilizados como ferramenta de análise do corpus.Por meio deles, analisa-se se as construções constituídas pelo verbo senden e o sintagma preposicional an denotam um evento de posse causada ou de movimento causado. Apresentam-se preceitos abordados por Adler (2011) em seus estudos sobre a alternância dativa na língua alemã, que auxiliam na distinção do evento denotado pela construção. Assim, a pesquisa realizada corrobora as reflexões da autora sobre a nova faceta da preposição an que aparece em verbos de transferência - o addressee-an, sustentando sua argumentação sobre o fato de que não são as variantes do objeto duplo (dativo), ou do sintagma preposicional (no caso, an) as responsáveis pelo evento denotado pela construção, mas sim os argumentos que a constituem. Essa pesquisa também propõe outro tipo de classificação para a análise de verbos da língua alemã que denotam eventos de transferência em orações destituídas de agente volitivo: evento causal como transferência (GOLDBERG 1995), no qual X CAUSA Y (AFETADO)A RECEBER Z (EFEITO).
Die Besitznahme der Oberrheinlande durch Rom – Aspekte einer Bevölkerungs- und Militärgeschichte
(2017)
Römer, Kelten und Germanen haben ihren festen Platz in der historischen Erinnerung. Dies betrifft nicht nur epochale Vorgänge und Ereignisse von weitreichender, gleichsam weltgeschichtlicher Bedeutung, sondern auch solche von begrenzter zeitlicher wie räumlicher Relevanz. Letzteres gilt auch für das Gebiet von Hoch- und Oberrhein mit einer eigenen Geschichte, die selbstverständlich ihrerseits zugleich in übergreifende historische Prozesse eingebettet ist. Im Folgenden wollen wir uns eingehender nur mit der frühen Phase der Begegnung zwischen Römern und jenen Völkerschaften befassen, die gemeinhin den Kelten bzw. den Germanen zugeordnet werden, und einige wichtige Aspekte der Bevölkerungsgeschichte der Oberrheinlande am Übergang von der Latènezeit zur römischen Epoche thematisieren. Mit dieser eng verbunden ist die römische Heeresgeschichte, der wir für die Zeit von Caesars Feldzug in Gallien bis zum Ende der iulisch-claudischen Dynastie wenigstens in einigen Grundzügen nachgehen wollen. Die unter ganz anderen historischen Bedingungen erfolgten Angriffe mit der folgenden Landnahme der Alamannen und Franken ab dem 3. Jahrhundert n. Chr. blenden wir aus; dies wäre Gegenstand einer eigenen Analyse. Trotz bemerkenswerter Fortschritte der jüngeren Vergangenheit ist allerdings nicht zu übersehen, dass nach wie vor eines der Hauptprobleme der modernen Forschung zur frühen Geschichte des hier im Zentrum des Interesses stehenden Raumes im sachgerechten Verständnis des Übergangs von der protohistorischen zur römischen Epoche besteht. Jedoch scheint zumindest darin weitgehend Konsens zu bestehen, dass – wie Lars Blöck in seiner jüngst publizierten, detailreichen Dissertation zur Besiedlung des südlichen Oberrheingebietes vermerkt. – "der Übergang von der Spätlatène- zur römischen Zeit innerhalb der Besiedlungsgeschichte [---] einen tiefgreifenden Einschnitt darstellt." ...
Aus der Distanz von beinahe zwei Dekaden werden der Literaturstreit und die daran anschließende Stasi-Debatte in dem selbsterkundenden Buch Stadt der Engel als Gewaltdiskurs wahrgenommen und ambivalent reflektiert. Die erzählerische Reflexion dieses Diskurses ist allerdings in ein Geflecht von Gewaltnarrativen eingebettet, das nur schwer zu entwirrenund zu entschlüsseln ist. Der vielschichtige Text ist jedoch nicht auf die literarische Vergegenwärtigung der strukturellen Gewalt im DDR-Regime oder der symbolischen Gewalt in den medialen Kontroversen zu reduzieren, ebenso wäre die Einschränkung auf die quälende Selbstbefragung der Erzählerin im Zusammenhang mit ihren in Vergessenheit geratenen Stasi-Kontakten und damit der eigenen Verstrickung in die Gewaltstrukturen eine unzulässige Vereinfachung.
The paper provides an overview and an economic analysis of the development of the corporate governance of German banks since the 1950s, highlighting peculiarities – as seen from the meanwhile prevailing standard model perspective – of the German case. These peculiarities refer to the specific German notion and legal-institutional regime of corporate governance in general as well as to the specific three-pillar structure of the German banking system.
The most striking changes in the corporate governance of German banks during the past 50 years occurred in the case of the large shareholder-owned banks. For them, capital markets have become an important element of corporate governance, and their former orientation towards the interests of a broadly defined set of stakeholders has largely been replaced by a one-sided concentration on shareholders’ interests. In contrast, the corporate governance regimes of the smaller local public savings banks and the local cooperative banks have remained virtually unchanged. They acknowledge a broader horizon of stakeholder interests and put an emphasis on monitoring.
The Great Financial Crisis, beginning in 2007, has led to a considerable reassessment in the academic and political debate on bank governance. On an international level, it has revived the older notion that, in view of their high leverage and their innate complexity, banks are “special” and bank corporate governance also – and needs to be seen in this light, not least because research indicates that banks with a strong and one-sided shareholder orientation – and thus with what appears to be the best corporate governance according to the standard model – have suffered most in the crisis. In the German case, the crisis has shown that the smaller local banks have survived the crisis much better than large private and public banks, whose funding strongly depends on wholesale markets. This may point to certain advantages of their governance and ownership regimes. But the differences in the performance during the crisis years may also, or even more so, be a consequence of the business models of large vs small banks than of their different governance regimes.
Mit dem Beitrag von Lis Hansen zu den "Verdammte[n] Dinge[n] - Tabu und Müll in der Literatur" wenden wir uns im Anschluss der Betrachtung von Tabus und ihrer Überschreitungen in der Literatur zu. Hansen begreift Müll dabei im Sinne von Mary Douglas als Medium der Ordnungsstiftung und weist dem ordnungstiftenden Akt des Entsorgens mit Kristevas Abjekt-Begriff identitätsstiftende Funktion zu. Damit sind Müllprodukte jedoch auch fortwährend eingebunden in einen Kreislauf von Bedeutungsverlust und Sinnstiftung. Anhand verschiedener Beispiele der deutschsprachigen Gegenwartsliteratur zeigt sie, wie die ausrangierten, erneut aufgefundenen Dinge für ihre Finder das Potential bereithalten, Lebensgeschichten zu erzählen und Sinnverlust in Sinnproduktion verwandeln können. Dabei setzt die Möglichkeit eines neuen Sinnarrangements aus dem Verworfenen poetisches Potential im Sinne eines semantischen Spiels frei, so dass dem Begriff Recycling hier eine neue, gleichsam poetisch gewendete Funktion zukommen kann.
Benjamin Hein beschäftigt sich im Beitrag "Über die Dethematisierung der Judenverfolgung und des Holocaust in der Populärliteratur der Nachwendezeit" mit den gegenwärtigen literarischen Aufarbeitungstendenzen der NS-Vergangenheit. Er untersucht, wie das Fortwirken eines Authentizitätsanspruchs und eines damit verbundenen 'Bildverbots' in der Schrifsteller-Generation der Nachgeborenen sowie der dritten Generation eine Aussparung der Opferperspektive zeitigt, die eine brisante Leerstelle produziere.
This paper analyzes the relationship between monetary policy and financial stability in the Banking Union. There is no uniform global model regarding the relationship between monetary policy-making on the one hand, and prudential supervision on the other. Before the crisis, EU Member States followed different approaches, some of them uniting monetary and supervisory functions in one institution, others assigning them to different, neatly separated institutions. The financial crisis has underlined that monetary policy and prudential supervision deeply affect each other, especially in case of systemic events. Even in normal times, monetary and supervisory decisions might conflict with each other. After the crisis, some jurisdictions have moved towards a more holistic approach under which monetary policy takes supervisory considerations into account, while supervisory decisions pay due regard to monetary policy.
The Banking Union puts prudential supervision in the hands of the European Central Bank (ECB), the institution responsible for monetary policy. Nevertheless, at its establishment there was the political understanding that the ECB should follow a policy of meticulous separation in the discharge of its different functions. This raises the question whether the ECB may pursue a holistic approach to monetary policy and supervisory decision-making, respectively. On the basis of a purposive reading of the monetary policy mandate and the SSM Regulation, the paper answers this question in the affirmative. Effective monetary policy (or supervision) requires financial stability (or smooth monetary policy transmission). Moreover, without a holistic approach, the SSM Regulation is more likely to provoke the adoption of mutually defeating decisions by the Governing Board. The reputation of the ECB would suffer considerably under such a situation – in a field where reputation is of paramount importance for effective policy.
As any meticulous separation between monetary and supervisory functions turns out to be infeasible, the paper explores the reasons. Parting from Katharina Pistor’s legal theory of finance, which puts the emphasis on exogenous factors to explain the (non)enforcement of legal rules, the paper suggests a legal instability theorem which focuses on endogenous reasons, such as law’s indeterminacy, contextuality, and responsiveness to democratic deliberation. This raises the question whether the holistic approach would be democratically legitimate under the current framework of the ESCB. The idea of technocratic legitimacy that exempts the ECB from representative structures is effectively called into question by the legal instability theorem. This does not imply that the independence of the ECB should be given up, as there are no viable alternatives to protect monetary policy against the time inconsistency problem. Rather, any solution might benefit from recognizing the ECB in its mixed technocratic and political shape as a centerpiece of European integration and improving.
With an incident in Palo Duro Canyon, Texas, USA, Scolopendra heros Girard (Chilopoda: Scolopendromorpha: Scolopendridae) becomes the third centipede species known to prey on bats; S. gigantea Linnaeus and S. viridicornis Newport have been so documented in Venezuela and Brazil, respectively. The Texas predation was interrupted by the predator/prey pair’s falling around 15–20 m from the canyon wall and, perhaps also, by human presence where they landed. The centipede uncoiled and retreated to shelter under a nearby rock and, after initial immobilization, so did the bat.
Ptyoiulus Cook 1895, the dominant parajulid diplopod genus in the eastern United States (US), comprises two species – P. impressus (Say 1821), with a slanted, fl ared, circumferentially entire, and marginally serrate apical calyx on the anterior gonopod coxal process, and P. montanus (Cope 1869), n. comb., with a smooth, upright, cupulate calyx that is open caudad and coaxial with the process’ stem. The genus occupies a broad area between the Mississippi River and Atlantic Ocean extending from southern New England, Ontario, and Michigan to the Florida Panhandle and four small disjunct ones – from Montreal, Québec, to northern Vermont, along southwestern Lake Michigan in Wisconsin and Illinois; northeastern/eastcentral Arkansas, primarily in Crowley’s Ridge physiographic feature and beside the “bootheel” of Missouri; and a point locality in northeastern Louisiana just south of the Arkansas line. A male from Chester County (Co.), Pennsylvania, is designated as the neotype of Julus impressus, as is one from Durham Co., North Carolina, for J. montanus. As both species inhabit Montgomery Co., Virginia, the type locality of J. montanus, we exercise the right of first reviser, conserve the latter name, and assign it to the species with the smooth, cupulate, and coaxial calyx. We also exercise first reviser rights and assign Parajulus ectenes Bollman 1887 to this form, thereby relegating it to synonymy under Ptyoiulus montanus. Other new synonymies include Ptyoiulus georgiensis Chamberlin 1943 under P. impressus and P. coveanus Chamberlin 1943 under P. montanus. Both Ptyoiulus and P. impressus are projected for Delaware and Rhode Island and newly reported from Québec, Connecticut, District of Columbia, Maryland, Mississippi, South Carolina, Vermont, West Virginia, and Wisconsin, and the genus and species, respectively, are newly documented from Louisiana and Arkansas; P. montanus is newly cited from Alabama, Arkansas, Georgia, Mississippi, and South Carolina. Ptyoiulus impressus occupies every state except perhaps Louisiana and is the only species in areas that were inundated during the Cretaceous and glaciated during the Pleistocene; by contrast, P. montanus inhabits a relatively narrow east/west transect through the center of the generic range. Their distribution patterns suggest an old species, montanus, being actively displaced by the younger and more successful impressus. The decurvature of the epiproct in uroblaniulinines appears to increase with age and developmental stage. A key is presented to parajulid familygroup taxa in the US and Canada east of the Rocky Mountains.
A trimaculate male of the diplopod genus Apheloria Chamberlin (Polydesmida: Xystodesmidae/-inae: Apheloriini) from 1.3 km (0.8 mi) west of McKenney, Dinwiddie County (Co.), Virginia, is designated the Neotype of Julus virginiensis Drury 1770, thereby stabilizing the earliest name for a North American milliped and authenticating its prior assignment to this taxon. The existing concept of Apheloria is accepted in the absence of a revisionary treatment, and a modern description of A. v. virginiensis with gonopod drawings and color photos is provided. Drury’s original account and his letter to the Virginian who sent him the original specimens are quoted verbatim to eliminate future library searches. The specific name has been associated with at least three genera, and its confusing history is clarified by summarizing works in each. Authentic localities, mapped to the extent now possible, reveal a distribution south of the James River in piedmont and coastal Virginia that extends southwestward to the Blue Ridge foothills and at least as far south in North Carolina (NC) as Greensboro, the “Triangle” (Raleigh/Durham/Chapel Hill region), and Albemarle Sound in the east. Based on the holotypes, A. aspila and A. tigana, both by Chamberlin, are placed in synonymy under A. v. virginiensis (syns. nov.), and although its status is still under review, A. waccamana Chamberlin, whose type locality is Lake Waccamaw, Columbus Co., in southeastern NC, may be the correct name for today’s A. tigana. All samples so labeled must be reexamined for misidentifications of A. v. virginiensis.
Gemeinsam mit dem Fach Germanistik an der Universität Stockholm richten die Fächer Germanistik und Translation Deutsch der Universität Helsinki in Zusammenarbeit mit dem Goethe-Institut Finnland und der Botschaft der Republik Österreich in Finnland vom 23. bis 25. August 2017 die siebente internationale Tagung zur kontrastiven Medienlinguistik aus. Der thematische Rahmen dieser Tagung lautet: Medienkulturen - Multimodalität und Intermedialität.
Die humane 5-LO ist das Schlüsselenzym in der LT-Biosynthese. LTs sind wichtige Entzündungsmediatoren und sind in einer Vielzahl von Krankheiten involviert, u. a. Asthma, Atherosklerose, rheumatische Arthritis, Sepsis, allergischen Reaktionen und in vielen Krebsarten. Die Struktur der 5-LO besteht aus 673 Aminosäuren und besitzt ein Molekulargewicht von 78 kDa. Sie ist in zwei Domänen unterteilt: die kleinere C2-ähnliche regulatorische Domäne (C2ld) und der größeren katalytischen Domäne. Die 5-LO besitzt NIS und NES, die für die zelluläre Lokalisation der 5-LO verantwortlich sind. Außerdem wird die Lokalisation noch von Phosphorylierungsstellen reguliert, die auf der katalytischen Domäne identifiziert werden konnten. 2011 konnten Häfner et al. zeigen, dass die 5-LO in der Lage ist Homodimere zu bilden.
Wie für die meisten anderen humanen Gene konnten auch bei der 5-LO alternative Spleißvarianten identifiziert werden. Schon 1992 konnten die ersten unterschiedlich gesüleißten Transkripte in Hirntumoren und differenzierten HL-60-Zellen gefunden werden. Später konnten weitere Isoformen in verschiedenen Zelllinien entdeckt werden.
In der vorliegenden Arbeit wurden die alternativen Spleißvarianten 5-LO∆13, 5-LO∆4 und 5-LOp12 untersucht und charakterisiert. Auf mRNA-Ebene wurde die Expression des 5-LO-WT und deren Isoformen sowohl in B- und T-Zelllinien als auch primären B- und T-Zellen, monozytären Zelllinien und primäre Monozyten aus Patientenproben (RA und Sepsis) untersucht. Es wurde festgestellt, dass das Expressionsprofil der 5-LO-Varianten zellspezifisch ist. Im Vergleich zu den T-Zellen konnte in B-Zelllinien ein höheres Expressionslevel detektiert werden. Des Weiteren zeigte sich interessanterweise ein stark erhöhtes Expressionslevel in primären Monozyten von RA- und Sepsis-Patienten.
Untersuchungen der 5-LO-Aktivität ergaben unterschiedliche Ergebnisse, abhängig von der Transfektionsmethode. Als transiente Transfektion diente die Calciumphosphat-Methode. Für die stabile Integration der HEK293T-Zellen wurde die Sleeping Beauty-Methode gewählt. Hierfür wurden Proteine mit einem GFP bzw. mCherry-Tag (GFP-5-LO-WT, mCherry∆13, mCherry∆4, mCherryp12) verwendet, um diese mittels Konfokalmikroskop visualisieren zu können. Nach transienter Transfektion konnte eine Inhibition der 5-LO-Aktivität nach Kotransfektion mit jeweils einer Isoform gemessen werden. Nach stabiler Integration jedoch zeigte sich eine Steigerung der 5-LO-Produktbildung. Mit Hilfe von Western Blots wurden Expressionskontrollen angefertigt und die Menge des 5-LO-WT quantifiziert. In transient transfizierten Zellen wurde eine Erniedrigung der Expression des 5-LO-WT bestimmt, wohingegen in stabil integrierten Zellen ein Anstieg des 5-LO-WT als auch der Isoformen beobachtet werden konnte. Einerseits könnte dies einem Artefakt der Transfektionmethode zugrunde liegen, andererseits könnte es ein Hinweis darauf sein, dass sich die Proteine gegenseitig in ihrer Expression beeinflussen.
Ebenso wurde die Lokalisation der 5-LO und deren Isoformen untersucht. Es konnte gezeigt werden, dass die 5-LO überwiegend im Zellkern lokalisiert ist, während alle alternativen Protein-Isoformen im Zytosol zu finden waren. Durch Ionophor-Behandlung wurde eine Translokation des 5-LO-WT an die Kernmembran detektiert, die Isoformen verblieben im Zytosol. Überraschenderweise konnte beobachtet werden, dass die Spleißvariante 5-LO∆13 mit höherer Ionophor-Konzentration ebenso in der Lage ist an die Kernmembran zu translozieren. Um eine mögliche Interaktion der 5-LO mit den Isoformen zu untersuchen, sollten alle Proteine im selben Zellkompartiment lokalisiert sein. Dafür wurden verschiedene Stimuli und Mutationen getestet. Mit der Mutante GFP-5-LO-S271A und dem Stressstimulus Sorbitol und den CaMKII/p38-Inhibotoren KN-93/SB203580 konnte eine Translokation in das Zytosol erreicht werden. Die Ergebnisse der anschließenden Aktivitätsassays zeigten, dass die Isoformen keinen Einfluss auf die Aktivität der 5-LO ausüben.
Des Weiteren wurden die Phosphorylierungen an S523 und S271 von 5-LO-WT, 5-LO∆13, 5-LO∆4 und 5-LOp12 untersucht. Es wurde herausgefunden, dass die 5-LO-Proteine unterschiedliche Phosphorylierungsmuster aufweisen. Während 5-LO-WT und 5-LO∆4 eine schwache Phosphorylierung an S271 aufzeigen, konnte eine starke Phosphorylierung der 5-LO∆13 und 5-LOp12 detektiert werden. Im Vergleich dazu zeigte lediglich die Isoform 5-LOp12 eine sehr starke Bande an der Phosphorylierungsstelle S523. Bei beiden Phosphorylierungen konnten deutlich stärkere Signale nach Kotransfektion gemessen werden. Durch Klonierung eines P2A-Linkers zwischen 5-LO und des GFP-Tags, konnten die Isoformen vom 5-LO-WT in Western Blots voneinander getrennt werden. Dies zeigte, dass es zu einer Hochregulation der Expression der alternativen 5-LO-Varianten nach Kotransfektion mit dem WT führte, aber auch, dass die stärkere Phosphorylierung nach Kotransfektion unabhängig von der Proteinmenge ist.
On the 28th of July, a 26 year old man, Ahmad A. launched a knife attack in a supermarket in the Barmbek area of Hamburg, wounding four people and killing one. He fled the scene of the attack before being forcefully apprehended by some bystanders. The attacker, a rejected asylum seeker, was understood by the police to have been recently religiously radicalised. Hamburg’s Interior Minister Andy Grote explained that he was known to the police as an “Islamist but not a jihadist” and was suspected of having psychological problems. Prosecutors have asserted that he had no known connections with any organized radical network or group and that he had planned on dying as a martyr...
Atheism remains one of the most extreme taboos in Saudi Arabia. It is a red line that no one can cross. Atheists in Saudi Arabia have been suffering from imprisonment, maginalisation, slander, ostracisation and even execution. Indeed, atheists in Saudi are considered terrorists. Efforts for normalisation between those who believe and those who don’t remain bleak in the kingdom.
Despite constant warnings of Saudi religious authorities of “the danger of atheism”, which is, according to them, “equal to disbelieving in God”, many citizens in the kingdom are turning their back on Islam. Perhaps inter alia the Saudi dehumanising strict laws in the name of Islam, easy access to information and mass communication are the primary driving forces pushing Saudis to leave religion. Unfortunately, those who explicitly do, find themselves harshly punished or forced to live dual lives.
Ransomware wie WannaCry und Petya/NotPetya versetzten weltweit Unternehmen in Sorge und verursachen erheblichen Schaden. Dabei sind sie nur der sichtbare Teil einer unzureichenden Sicherheitskultur, die dringend ein Update benötigt.
Ransomware, auch Kryptotrojaner genannt, sind kein neues Phänomen, sondern die zunehmend sichtbare Begleiterscheinung kollektiver IT-Unsicherheit. Die Ransomware WannaCry infizierte Mitte Mai weltweit mindestens 220.000 Windows Rechner. Dabei verschaffte sich der Trojaner Zugang zu den Dateien der Computer und verschlüsseln diese um eine Lösegeldzahlung zu erpressen. Dies war möglich über die als EternalBlue bekannte Lücke, die seit dem Betriebssystem Windwos XP auftrat und erst in diesem Jahr im Februar durch Microsoft geschlossen wurde. EternalBlue war für eine unbekannte Zeit in den Händen der NSA bis sie Anfang dieses Jahres durch eine Hackergruppe namens Shadow Brokers von der NSA „gestohlen“ und veröffentlicht wurde. Und obwohl Microsoft eiligst einen Patch veröffentlichte, offenbarten die bisher folgenreichsten bekannte Kryptowurm das Dilemma, in dem sich die Cyber-Sicherheitskultur aktuell befindet: Es ist eine Kultur des Schweigens, die dazu führt, dass das Sammeln und der Missbrauch von Sicherheitslücken gefördert statt verhindert wird....
Digitale Technologien und ihre vielfältige Nutzung verändern normative Ordnungen auf politischer, rechtlicher und gesellschaftlicher Ebene. Das Internet bietet neue gesellschaftliche Räume, die soziale Interaktion strukturieren. Diese sind jedoch nur halb-öffentliche Räume, in denen die Dienstleistungsanbieter mit Verweis auf ihre AGBs die Möglichkeit haben, etwa politische Äußerungen zu zensieren oder gar zu löschen. Darüber hinaus kooperieren manche private Unternehmen auch mit Staaten in der Strafverfolgung, und treffen Entscheidungen darüber welche Daten sie weitergeben. Welche Normen stoßen im Rahmen der Digitalisierung aufeinander und inwieweit sollten und könnten diese per Gesetz reguliert werden? Können die Grundrechte der Nutzer/innen noch umfassend gewährleistet werden? Mit diesen hochaktuellen Fragen befasste sich am 06. und 07. Juli die interdisziplinäre Konferenz “Normative Orders of the Digital“ am Exzellenzcluster Normative Ordnungen der Goethe-Universität Frankfurt.
Auf welche Weise offenbart sich der Einfluss bildungsadministrativer Vorgaben und fachwissenschaftlicher Diskurse im Geschichtsschulbuch? Die vorliegende Studie geht dieser Frage anhand einer diachronen Längsschnittuntersuchung zum mittelalterlichen "Lehnswesen" in hessischen Geschichtsschulbüchern zwischen 1945 und 2015 auf den Grund. Nach der Entwicklung eines möglichst repräsentativen Untersuchungskorpus wird auf Basis der verschiedenen Lehrpläne und mediävistischen Grundlagen ein Fragenkatalog für die anschließende Schulbuchanalyse entwickelt auf dessen Basis Veränderungen in den Schulbuchdarstellungen offengelegt und exemplarisch konkretisiert werden. Abschließend setzt die Studie die verschiedenen Einflussfaktoren bei der Erstellung neuer und der Überarbeitung alter Geschichtsschulbücher miteinander in Bezug und bewertet diese hinsichtlich ihrer Bedeutung für Veränderungen in Schulbüchern.
Measuring information processing in neural data: The application of transfer entropy in neuroscience
(2017)
It is a common notion in neuroscience research that the brain and neural systems in general "perform computations" to generate their complex, everyday behavior (Schnitzer, 2002). Understanding these computations is thus an important step in understanding neural systems as a whole (Carandini, 2012;Clark, 2013; Schnitzer, 2002; de-Wit, 2016). It has been proposed that one way to analyze these computations is by quantifying basic information processing operations necessary for computation, namely the transfer, storage, and modification of information (Langton, 1990; Mitchell, 2011; Mitchell, 1993;Wibral, 2015). A framework for the analysis of these operations has been emerging (Lizier2010thesis), using measures from information theory (Shannon, 1948) to analyze computation in arbitrary information processing systems (e.g., Lizier, 2012b). Of these measures transfer entropy (TE) (Schreiber2000), a measure of information transfer, is the most widely used in neuroscience today (e.g., Vicente, 2011; Wibral, 2011; Gourevitch, 2007; Vakorin, 2010; Besserve, 2010; Lizier, 2011; Richter, 2016; Huang, 2015; Rivolta, 2015; Roux, 2013). Yet, despite this popularity, open theoretical and practical problems in the application of TE remain (e.g., Vicente, 2011; Wibral, 2014a). The present work addresses some of the most prominent of these methodological problems in three studies.
The first study presents an efficient implementation for the estimation of TE from non-stationary data. The statistical properties of non-stationary data are not invariant over time such that TE can not be easily estimated from these observations. Instead, necessary observations can be collected over an ensemble of data, i.e., observations of physical or temporal replications of the same process (Gomez-Herrero, 2010). The latter approach is computationally more demanding than the estimation from observations over time. The present study demonstrates how to handles this increased computational demand by presenting a highly-parallel implementation of the estimator using graphics processing units.
The second study addresses the problem of estimating bivariate TE from multivariate data. Neuroscience research often investigates interactions between more than two (sub-)systems. It is common to analyze these interactions by iteratively estimating TE between pairs of variables, because a fully multivariate approach to TE-estimation is computationally intractable (Lizier, 2012a; Das, 2008; Welch, 1982). Yet, the estimation of bivariate TE from multivariate data may yield spurious, false-positive results (Lizier, 2012a;Kaminski, 2001; Blinowska, 2004). The present study proposes that such spurious links can be identified by characteristic coupling-motifs and the timings of their information transfer delays in networks of bivariate TE-estimates. The study presents a graph-algorithm that detects these coupling motifs and marks potentially spurious links. The algorithm thus partially corrects for spurious results due to multivariate effects and yields a more conservative approximation of the true network of multivariate information transfer.
The third study investigates the TE between pre-frontal and primary visual cortical areas of two ferrets under different levels of anesthesia. Additionally, the study investigates local information processing in source and target of the TE by estimating information storage (Lizier, 2012) and signal entropy. Results of this study indicate an alternative explanation for the commonly observed reduction in TE under anesthesia (Imas, 2005; Ku, 2011; Lee, 2013; Jordan, 2013; Untergehrer, 2014), which is often explained by changes in the underlying coupling between areas. Instead, the present study proposes that reduced TE may be due to a reduction in information generation measured by signal entropy in the source of TE. The study thus demonstrates how interpreting changes in TE as evidence for changes in causal coupling may lead to erroneous conclusions. The study further discusses current bast-practice in the estimation of TE, namely the use of state-of-the-art estimators over approximative methods and the use of optimization procedures for estimation parameters over the use of ad-hoc choices. It is demonstrated how not following this best-practice may lead to over- or under-estimation of TE or failure to detect TE altogether.
In summary, the present work proposes an implementation for the efficient estimation of TE from non-stationary data, it presents a correction for spurious effects in bivariate TE-estimation from multivariate data, and it presents current best-practice in the estimation and interpretation of TE. Taken together, the work presents solutions to some of the most pressing problems of the estimation of TE in neuroscience, improving the robust estimation of TE as a measure of information transfer in neural systems.
Optimal trend inflation
(2017)
We present a sticky-price model incorporating heterogeneous Firms and systematic firm-level productivity trends. Aggregating the model in closed form, we show that it delivers radically different predictions for the optimal inflation rate than canonical sticky price models featuring homogenous Firms:
(1) the optimal steady-state inflation rate generically differs from zero and,
(2) inflation optimally responds to productivity disturbances.
Using micro data from the US Census Bureau to estimate the inflation-relevant productivity trends at the firm level, we find that the optimal US inflation rate is positive. It was slightly above 2 percent in the year 1986, but continuously declined thereafter, reaching about 1 percent in the year 2013.

Ufocandona hannaleeae gen. et sp. nov. (Crustacea, Ostracoda) from an artesian well in Texas, USA
(2017)
We describe a new genus, Ufocandona gen. nov. with its type species Ufocandona hannaleeae gen. et sp. nov., from an artesian well in San Marcos, Texas, USA. The new genus has diagnostic characteristics that distinguish it from other genera in Candonidae, including the asymmetric shape of the valves, the smooth central area on the external surface of the valves, the hexagonal ornamentations around the marginal ends of the carapace, the dense spines on the marginal edges of the right valve and the dorsal prolongation and tubercles seen from inside the ventral edges of the left valve. Additional differences in the soft body parts of the male and female (e.g., claw-like uropod, shape of hemipenis, long Y aesthetascs, two short or reduced exopods on antenna, reduced numbers of setae and segments on other extremities) distinguish the new genus from others in the family. The discovery of this species from a deep artesian well contributes important information to our understanding of groundwater species diversity in a biologically diverse aquifer where the ostracod fauna has been unstudied.
Ebenso wie Pierre Bourdieu ist sein Schüler Loïc Wacquant einer der selten gewordenen Intellektuellen, die ihre Profession, die Soziologie, nutzen um soziale Ungleichheiten und gesellschaftliche Machtverhältnisse nicht nur zu analysieren, sondern auch versuchen, damit auf öffentliche Debatten zu einzuwirken. Daher ist Wacquants Aufsatz nicht nur als eine interessante Diskussion der Frage, ob Bourdieus Werk in der Stadtsoziologie angemessen und korrekt verwendet werde, zu verstehen. Der in dem Text formulierte Appell, Bourdieus Arbeit auch innerhalb der Stadtsoziologie stärker anzuwenden, ist – vor dem Hintergrund zunehmender sozialer Ungleichheit, Armut, Marginalisierung und einem Aufschwung des Rechtspopulismus – eine Forderung nach einer soziologischen Betrachtung dieser Probleme in der Stadt. Was kann nun also das Werk von Pierre Bourdieu zur Analyse der heutigen sozialen Probleme in der Stadt in Deutschland beitragen?

Forensic entomology
(2017)
For many members of the forensic community, insects still have an exotic status. This may be one reason why forensic entomology, the analysis of insect evidence for forensic and legal purposes, has not yet achieved the significance it deserves in forensic sciences. The present special issue may help to change that. ...
Autophagy in cancer therapy
(2017)
Autophagy represents a catabolic program involved in the degradation of cellular components via lysosomes. It serves to mitigate cellular stress and to provide metabolic precursors especially upon starvation. Thereby, autophagy can support the survival of cancer cells. In addition, there is now convincing evidence showing that under certain conditions autophagy can also foster cell death. This dual function of autophagy is also relevant upon anticancer treatment, as many chemotherapeutic agents engage autophagy. A better understanding of the molecular mechanisms that are critical for mediating autophagic cell death in cancer cells will be instrumental to selectively interfere with this cellular program in order to increase the cancer cell’s response to cytotoxic drugs. This review illustrates how anticancer drug-induced autophagy is involved in mediating cell death.
We review the recent developments of analytic solutions in transverse magneto-hydrodynamics under Bjorken expansion. It is found that the time dependence of magnetic fields can either increase or reduce the energy density depending on the decay exponent of magnetic fields. Moreover, perturbative solutions under weak magnetic fields with spatial inhomogeneity results in transverse flow, where the directions of flow also depend on the decay exponent of magnetic fields in time.
To understand the policy environment within which refugees establish and operate their enterprises in South Africa's informal sector, this report brings together two streams of policy analysis. The first concerns the changing refugee policies and the erosion of the progressive approach that characterized the immediate post-apartheid period. The second concerns the informal sector policy, which oscillates between tolerance and attempted destruction at national and municipal levels. While there have been longstanding tensions between foreign and South African informal sector operators, an overtly anti-foreign migrant sentiment has increasingly been expressed in official policy and practice. This report describes the strategies being used to turn South Africa into an undesirable destination for refugees, including the setting up of additional procedural, administrative and logistical hurdles; the undercutting of court judgments affirming the right of asylum-seekers and refugees to employment and self-employment; ensuring that protection is always temporary by making it extremely difficult for refugees to progress to permanent residence and eventual citizenship; and restricting opportunities to pursue a livelihood in the informal sector. The authors conclude that the protection of refugee rights is likely to continue to depend on a cohort of non-governmental organizations prioritizing migrant livelihood rights and being willing and able to pursue time-consuming and costly litigation on their behalf.

The Heart of Jacob
(2017)
Jacob prospers as a moneylender and pig merchant by taking advantage of other peoples misfortunes. But when he seeks to exploit the famine afflicting his village Tounga by lending money at high interest rates to poor villagers, he does not reckon what a sacrilege his pigs would commit which give the people an opportunity to feast on his own misfortune. When this happens community gives way to individual desires, and the stomach dictates to the head what it should think and believe in. Reason bends to absurdity and custom bows to bizarre novelty. Life explodes into a sinister mess that points to only one outcome: Jacob and societys ultimate ruin.
My Head Master
(2017)
I first time I saw the man who became my headmaster was when he rode his motorcycle past our house in Tyosa. He was a huge, dark, hairy man with big eyeballs that looked like they could see through anything and often saw through everything. His eyes were so frightening to me that I always trembled whenever he turned them on me. Not only were the eyeballs big, he had a way of baring them in the most frightening manner when he focused them on you. Older people said his father Akut was nicknamed Akut the owner of frightening eyes for pretty much the same reason. His eyeballs were said to be so big as to scare away birds whenever he entered the forest. Some people said they scared away chickens too. So he was called Akut the owner of frightening eyes.... But Akuts son was headmaster and no one dared pass his nickname to his son though he had passed his frightening eyes to the son. No one dared sing songs behind him the way children used to sing behind Akut his father Passing through and growing up in school with Akuts son as the Headmaster, and what it took to grow up in a closely-knit community through the eyes and memory of a pupil is a story that has to be told, the story of any pupil. And this is the story

In 1996 President Nelson Mandela described Professor Ali A. Mazrui (1933-2014) as 'an outstanding educationist and freedom fighter.' In 2002 the former UN Secretary General Kofi Annan referred to Professor Mazrui as 'Africa's gift to the world.' Author of more than 35 books and hundreds of articles, Professor Mazrui was an African scholar who had treated with uncommon verve and flair a wide-range of themes that included globalization, the triple heritage, peace, and social justice. This volume engages with some of those themes that excited his mind for over six decades. The multidisciplinary essays seek to underline the highlights of Mazrui's intellectual journey and attest to the fact that he was public intellectual par excellence. Indeed, in 2005, he was named one of the top 100 public intellectuals in the world. This book is a product of a symposium held from 15 to 17 July 2016 in Nairobi, Kenya. The symposium was jointly organized by the Twaweza Communications, Nairobi, Kenya, and the Institute of Global Cultural Studies (State University of New York at Binghamton) which Ali Mazrui created and presided over as the Albert Schweitzer Professor in the Humanities from 1991 to 2014.
Characterization of a novel KCNJ2 sequence variant detected in Andersen-Tawil syndrome patients
(2017)
Background: Mutations in the KCNJ2 gene encoding the ion channel Kir2.1 have been linked to the Andersen-Tawil syndrome (ATS). Molecular genetic screening performed in a family exhibiting clinical ATS phenotypes unmasked a novel sequence variant (c.434A > G, p.Y145C) in this gene. The aim of this study was to investigate the effect of this variant on Kir2.1 ion channel functionality.
Methods: Mutant as well as wild type GFP tagged Kir2.1 channels were expressed in HEK293 cells. In order to examine the effect of the new variant, electrophysiological measurements were performed using patch clamp technique. Cellular localization of the mutant in comparison to the wild type ion channel was analyzed by confocal laser scanning microscopy.
Results: The currents of cells expressing only mutant channels or a mixture of wild type and mutant were significantly reduced compared to those expressing wild type (WT) channels (p < 0.01). Whereas WT expressing cells exhibited at −120 mV an averaged current of −4.5 ± 1.9 nA, the mutant generates only a current of −0.17 ± 0.07 nA. A co-expression of mutant and WT channel generates only a partial rescue of the WT current. Confocal laser scanning microscopy indicated that the novel variant is not interfering with synthesis and/or protein trafficking.
Conclusions: The detected sequence variant causes loss-of-function of the Kir2.1 channel and explains the clinical phenotypes observed in Andersen-Tawil syndrome patients.
Der vorliegende Beitrag kann keinen umfassenden Überblick über die Literaturgeschichte moderner Engel in Aussicht stellen. Stattdessen möchte ich das vielseitige und zugleich ambivalente Nachleben der Figur und die divergierende Gestaltung religiöser Sinn- und Anspielungshorizonte textnah anhand von Gotthold Ephraim Lessings 'Nathan der Weise' (1779) und Heinrich von Kleists 'Das Käthchen von Heilbronn' (1808/10) untersuchen.
Welche Signifikanz sich das über die 'Geistlichen Übungen' geregelte Bildliche bewahrt hat, möchte ich im Folgenden anhand einer Erzählung aus den 'Nachtstücken' E.T.A. Hoffmanns, der 'Jesuiterkirche in G.' aus dem Jahre 1816, skizzieren, die sich bei genauer Betrachtung als eine literarische Abhandlung über das jesuitische Bild- und Wahrnehmungsverständnis zu erkennen gibt.
Im Folgenden soll die gegenseitige Befruchtung von Kunstschaffen und Religion am Beispiel Ludwig Meidners, einer der Doppelbegabungen aus dem Umkreis des Expressionismus, vorgeführt werden, der als Maler und Zeichner und Schriftsteller hervorgetreten ist. Interessant scheint das Exempel auch deshalb, weil gezeigt werden kann, wie die Bezogenheit auf das Heilige die Medien Text und Bild durchzieht und so in besonderer Weise transgressiv wirksam wird.
Der vorliegende Essay möchte die Verbindung von Philosophie und Religion näher ausführen und sie exemplifizieren anhand der Exegese der Bibel im 'Stern der Erlösung'. Hierfür sollen zunächst ein paar einleitende Worte zur Biographie Rosenzweigs angeführt werden, da bei diesem Denker, wie bei kaum einem zweiten der jüdischen Moderne, Leben und Werk eng aufeinander bezogen sind. Daran anschließend konzentriere ich mich auf den 'Stern', um herauszuarbeiten, wie Rosenzweig die Bibel benutzt, um gewisse für sein Denken zentrale philosophische Sachverhalte anhand von Bibelstellen zu erläutern.
Im ersten Teil der vorliegenden Analyse werden zwei Themen in Jungs Schrift untersucht: die Amoralität und Unbewusstheit Gottes sowie dessen Menschwerdung. Dann soll erörtert werden, wie Jung zu seiner Interpretation kommt, und schließlich wird gezeigt, welche Bedeutung Jung der Hiobschrift für das 20. Jahrhundert und danach beimisst.
Die Bibel ist Weltliteratur 'und' eine heilige Schrift - damit spreche ich sowohl bereits den Kern des Beitrages als auch die Schwierigkeit dieser Konstellation an. In welchem Verhältnis steht die Bibel als Literatur zu dem Begriff der Heiligkeit, der ihr kanonisch, normativ und auch inhaltlich zuerkannt wurde und teils wird? Beide Aspekte, sowohl ihre Literarizität (1. 'Bible as Literature') als auch ihre Einordnung als eine heilige Schrift (2. Die Bibel als heilige Schrift), werden im Folgenden in einem Wechselspiel aus literaturwissenschaftlicher und theologischer Hermeneutik untersucht, da diese beiden Disziplinen die Bibel als literarisches und/oder religiöses Medium wahrnehmen und aufgreifen.
The East African Rift System (EARS) was initiated in the Eocene epoch between 50 and 21 Ma probably due to the influence of mantle plumes that caused volcanism, flood basalts and rifting extensions in Ethiopa and the Afar region. As a result of magmatic intrusions and adiabatic decompression melting within the lithosphere caused by the impact of the Kenya plume, there was a southward propagation of the EARS of about 30 – 15 Ma from Ethiopia to Kenya, which coincide with the occurrence of volcanism. The EARS developed towards the south along the margins of the Tanzania Craton between 15 and 8 Ma. Previous findings of low-velocity anomalies within the upper mantle and the mantle transition zone indicate an upwelling of hot mantle material in the vicinity of the Afar region and the East African Rift. This study includes the analysis of P- and S-receiver functions in order to determine further impacts on the lithosphere from below. The aim was to determine the topographic undulations of further boundary layers and to identify their variability owing to the rifting processes and the formation of the EARS. The study area included the Tanzania Craton and the surrounding rift branches of the East African Rift System.
The region of the Rwenzori Mountains can be analysed in detail because of the large dataset of the RiftLink project. The use of the P-receiver function technique and the H-K stacking method enabled to determine different vP /vS ratios depending on the tectonic setting in the Rwenzori region: Rift shoulders (vP /vS =1.74), Albert Rift segment (vP /vS =1.80), Edward Rift segment (vP /vS =1.87) and Rwenzori Mountains (vP /vS =1.86). To determine the topography of the Moho, it is necessary to take into account the thickness of the sedimentary layer, the surface topography, the azimuthal variations in crustal thickness and the impact of local anomalies. After correcting these effects on the Moho depths, significant variations in Moho topography could be determined. The Moho depths range from 29 to 39 km beneath the rift shoulders of the Albertine Rift. Within the rift valley, the crustal thickness varies between 25 – 31 km in the Edward Rift segment and 22 – 30 km in the Albert Rift segment. An averaged crustal thickness of about 26 km within the rift valley indicates the lack of the crustal root beneath the Rwenzoris. Similar variations in crustal thickness were determined by using an automatic procedure for analysing S-receiver functions that was developed in this study.
The S-receiver functions are created by applying a rotation criterion in order to rotate the Z, N and E components into the L, Q and T components. It is necessary to perform trial rotations using different incident and azimuth angles to determine the correct rotation angles. The latter are identified by the use of the rotation criterion, including the amplitude ratio of the converted Moho signal to the direct S/SKS-wave signal. The L component is rotated correctly in the direction of the incident shear wave in the case of the maximum amplitude ratio. After analysing the frequency content of the receiver functions in order to sort out harmonic and long-periodic traces, the individual Moho signals are checked for consistency in order to remove atypic signals. To increase the signal-to-noise ratios on the traces, the S-receiver functions are stacked. For this purpose, the signals of the direct shear waves must originate from similar epicenters. On the basis of similar ray paths, the receiver functions show comparable waveforms and converted signals. To perform the stacking procedure, it is necessary to merge the datasets of the adjacent stations in order to obtain a sufficient number of receiver functions. This analysis is based on the assumption that the incident seismic waves arriving at the adjacent stations penetrate to some extent the same underground structures in the case of similar wave propagation paths. This approach accounts for the fact that the converted signals do not result exclusively from the piercing points at the boundary layers. Further signals originate from the conversions at the boundary layer within the Fresnel Zone. The piercing points are derived from the significant signals in the receiver functions. Depending on the order of arrival of the converted phases on the traces, the signals are attributed to the theoretical discontinuities DIS1, DIS2, DIS3 and DIS4. However, partly due to the low signal-to-noise ratios on the traces, it is difficult to identify the real conversions on the traces and to ensure that the converted signals are attributed to the correct boundary layers. For this reason, it is necessary to check the consistency of the conversion depths among each other. In the case of inconsistent conversion depths, the corresponding signals are either adjusted to another seismic boundary layer or removed from the dataset. To verify the functionality of the automatic procedure and to determine the resolvability with respect to two boundary layers, several models are tested including horizontal and dipping discontinuities. To resolve distinct discontinuities, their depths must differ by at least 60 km, otherwise, due to similar depth ranges of the different boundary layers, the converted signals cannot be separated from each other. As a consequence, the converted signals that originate from different discontinuities are attributed to a single one. Further tests including break-off edges of seismic discontinuities are performed to check the attributions of the converted signals to the discontinuities. Owing to the varying number of boundary layers, the converted signals cannot be attributed to the discontinuities according to the order of their arrivals on the traces. It is necessary to correct their attributions to the seismic discontinuities in order to resolve the boundary layers.
The crust-mantle boundary and further discontinuities within the lithospheric mantle are investigated by applying this automatic procedure. Depending on the tectonic setting, the conversion depths of the Moho range from about 30 – 45 km beneath the western rift shoulder to 20 – 35 km within the rift valley up to 30 – 40 km beneath the eastern rift shoulder. The long wavelengths of the shear waves hamper the correct identification of the converted phases in the S-receiver functions. With respect to the relative differences in conversion depth, the topographic undulations of the crust-mantle boundary are consistent with the Moho depths derived from P-receiver functions. In contrast to the Rwenzori region, it is difficult to resolve completely the trend of the Moho in the remaining area of the East African Rift due to the small dataset provided by IRIS. The results exibit an increase in crustal thickness to up to 45 km in the region of the Cenozoic volcanics such as Virunga, Kivu, Rungwe and Kenya. The greatest Moho depths of more than 50 km are located near Mount Kilimanjaro. In addition to the Moho, the analysis of the S-receiver functions revealed two further boundary layers at depths of 60 – 140 km and 110 – 260 km, which are associated with a mid-lithospheric discontinuity and the lithosphere-asthenosphere boundary, respectively. The shallowest conversion depths of the LAB are focussed to small-scale regions within the rift branches, namely the northern Albertine Rift, the Chyulu Hills and the Mozambique Belt, which are located around the Tanzania Craton. The larger thickness of the lithosphere beneath the cratonic terrain indicates that the Tanzania Craton is not significantly eroded. However, there are indications that the lithosphere beneath the craton and the rift branches is penetrated by ascending asthenospheric melts to depths of up to 140 and 60 km, respectively. The top of the ascending melts is associated with the occurrence of the mid-lithospheric discontinuity. The shallowest conversion depths of this boundary layer (60 – 90 km) are related to the rifted areas of the EARS and the Cenozoic volcanic provinces, which are located along the Albertine Rift, the Kenya Rift and the Rukwa-Malawi rift zones. The deepest conversion depths of up to 140 km are related to the Rwenzori Belt, the Ugandan Basement Complex and the interior of the Tanzania Craton.
Auch wenn in der Nachfolge der Aufklärung sowie mit dem Siegeszug der modernen Naturwissenschaften eine Verlustgeschichte des Transzendenzwunders geschrieben wurde und Max Weber in seinem vielzitierten Diktum von 1917 die moderne Welt als 'entzaubert' deklarierte, entpuppte sich das vermeintlich vormoderne Phänomen des Wunders in der literarischen Moderne als Reflexionsgegenstand verschiedener Fachdisziplinen. Gleichzeitig erlebte das Wunder im Drama und Theater der Moderne eine Renaissance: Jener "clamor for miracles", so George Bernard Shaw in seinem Vorwort zu 'Androcles and the Lion', wird im zweiten Jahrzehnt des 20. Jahrhunderts in England nicht nur diskursiv verhandelt, sondern für das Publikum durchaus bühnenwirksam eingesetzt, wie ich im Folgenden erläutern möchte.
Indem Benjamin die "Umkehr" als zentrales Element herausgreift – also das Verwandeln von Leben in Schrift und nicht von Schrift in Leben -, löst er Kafka aus einer nur auf das Judentum beschränkten Bedeutung und zeigt dessen Relevanz für das Verständnis von Geschichte überhaupt. Die Form des Kafka’schen Werks enthalte "Hinweise auf einen Weltzustand". Insofern tut sich in der Auseinandersetzung zwischen Benjamin und Scholem bezüglich der Frage von Heiligkeit und Schrift etwas Neues auf: Wie wahre Hoffnung nur für die Hoffnungslosen ist, so erscheint das Verständnis echter Heiligkeit als rein theologischer Kategorie durch die Erkenntnis der nicht mehr heiligen Schrift bedingt.
Im Lichte der "Redevielfalt" basiert textuelle (Über‑)Heiligkeit auf drei Punkten: erstens auf einer Polyphonie, d. h. einer Vielzahl von divergenten Heiligkeitsdeutungen und -perspektiven sowie Weltanschauungen, die sich in der Orchestrierung des Autors brechen und ergänzen. Zweitens: Ein Mehrwert dieser textuellen (Über‑)Heiligkeit liegt darin, dass postmoderne und postkoloniale Literatur sich gegen religiöse und kulturelle Vorstellungen von dogmatischer Homogenität wendet und sich in dieser literarischen Opposition gegen dogmatische Denkvorstellungen von Heiligkeit richtet. Insofern entsteht eine "Ästhetik des Überschreitens" (Michael Hofmann), also eine neue Weltliteratur, die den Herausforderungen der Globalisierung entgegentritt und sich jeder engen nationalen, kulturellen sowie religiösen Zuschreibung definitiv entzieht. Meine Behauptung der Überheiligkeit bzw. der textuellen Redevielfalt über das Heilige ließe sich drittens und schließlich mit einer Beobachtung begründen: Viele Arbeiten über die Darstellung von 'heiligen Texten' in der Literatur untersuchen das Heiligkeitskonzept mit einem Fokus auf die Buchreligionen. Dabei wird oft übersehen, dass es auch Praktiken des Heiligen gibt, die nicht in einer Buchreligion entstehen bzw. die jenseits von Buchreligionen ihren Bestand haben. Es ist diese Überschreitung von gewohnten Apperzeptionen des Heiligen, nämlich die Vorstellung des Heiligen mit und ohne Buchreligion, die ich im Folgenden näher betrachten werde.
Die im religiösen Kontext entstandenen Formen des Umgangs mit Heil und Erlösung bleiben bis in die Gegenwart prägend für den literarischen Diskurs. Die Bibel stellt dabei einen zentralen Prätext dar, wobei in der Moderne nicht selten gerade ihre ambivalenten Erzählungen und Figuren in den Blick genommen werden. Auch mehrere Texte von Joseph Roth befassen sich mit der Frage nach dem Heil und beziehen sich dabei in unterschiedlicher Weise auf religiöse Literatur. Mit dem Roman 'Hiob. Roman eines einfachen Mannes' und der Novelle 'Die Legende vom heiligen Trinker' stehen zwei dieser Texte im Mittelpunkt der folgenden Überlegungen. Beide Texte greifen neben ihren expliziten Bezügen zur religiösen Literatur auf das Motiv der Wüstenwanderung und das damit verbundene Schema von Exil und Wiederkehr zurück, beziehen sich dabei aber auf je unterschiedliche religiöse Konzepte und Erzähltraditionen. Nicht zuletzt steht 'Hiob' in engem Bezug zur jüdischen Kultur Osteuropas, während die 'Legende' stärker an der christlichen Kultur orientiert ist.
Im Folgenden möchte ich drei Jesus-Biographien aus den 1920er Jahren analysieren, die zeigen, wie stark sich darin gleichermaßen der theologische und der literarische Diskurs der Zeit widerspiegelt. Es handelt sich dabei um Giovanni Papinis 'Lebensgeschichte Christi', auf Deutsch erschienen 1924, um Josef Wittigs 'Leben Jesu in Palästina, Schlesien und anderswo' von 1925, und um Emil Ludwigs 'Der Menschensohn' von 1928.
In der Moderne verändert sich der Umgang mit heiligen Texten und damit auch die traditionelle Praxis des Kommentars. Einerseits werden solche Texte nun auch wissenschaftlich und kritisch kommentiert, andererseits leben religiöse Kommentarformen auch in säkularen Kontexten fort: etwa in der Dichtung, der Philosophie oder der Philologie. Der Kommentar war lange der Königsweg der Auseinandersetzung mit klassischen, kanonischen und als "heilig" verstandenen Texten. Weil das Verständnis von Schriftlichkeit entscheidend davon geprägt ist, wie man Texte kommentiert, ist die Geschichte des Kommentars zentral, um die Entstehung der modernen säkularen Textkultur zu verstehen. Der Band fragt, wie die Kommentierung religiöser Texte unter den Bedingungen der Säkularisierung noch möglich ist. Er beleuchtet Denkfiguren und Textpraktiken, mit denen säkulare Texte sakralisiert werden und wie jene Verschiebungen unser Verständnis von Kommentar verändern.
Caroline Sauter beschäftigt sich am Beispiel der Theorie und Praxis des Kommentierens bei Walter Benjamin damit, wie traditionelle religiöse Kommentarformen in Kommentare zu moderner Literatur übertragen werden und vice versa. Dabei wird die strikte Grenzziehung zwischen Theologie und Säkularisierung unterlaufen, die gerade in der Benjaminforschung gerne bemüht und auf die Formel einer vermeintlichen Alternative von "Messianismus vs. Materialismus" gebracht wird. So zeigen zwei konkrete Beispiele aus Benjamins Einbahnstraße (1928) und seinen Brecht-Kommentaren (1938), dass Theologie und Philologie - laut Benjamin die beiden "Grundwissenschaften" des Kommentars - in seinem Kommentarwerk ineinander übergehen. Die Alternative von 'Theologie' einerseits und 'Säkularisierung' andererseits ist also für Benjamin nicht ohne weitere Differenzierung haltbar; vielmehr durchdringen die beiden Dimensionen einander gerade in seinem Umgang mit der Gattung des Kommentars, der ein kritisches Verständnis der Theologie selber anschaulich macht.
Die Frage ist, ob und in welcher Weise säkulare Texte auf religiöse Auslegungspraktiken und Deutungsmuster rekurrieren, und welche Verschiebungen dabei zwischen ihnen stattfinden. Die Autoren gehen dabei erstens davon aus, dass der Kommentar eine paradoxe Textpraxis ist, und zweitens davon, dass diese Paradoxie in der Moderne besonders dort manifest wird, wo sie sich mit denjenigen Paradoxien berührt oder überschneidet, die im Prozess der Säkularisierung entstehen.
Der Literatur- und Medienwissenschaftler Michael W. Jennings stellt in seinem Aufsatz die Bedeutung des theologischen Konzepts der 'apokatastasis' in Benjamins Texten heraus, das sich auf Origines' Lehre von der Wiederherstellung der Dinge am Ende der Zeiten bezieht. Nach Jennings basiert Benjamins Vorstellung, dass es in der Gegenwart noch keine Religion geben kann, auf der Überzeugung, dass die Bedingungen für die Möglichkeit von Religion erst nach dem Ende der Geschichte gegeben sind. In einem zweiten Schritt geht er den verborgenen Spuren des Konzepts der 'apokastastasis' in Benjamins medientheoretischen Schriften nach. Er zeigt, wie die im Kunstwerk-Aufsatz artikulierte Hoffnung, dass die vom Kapitalismus deformierten Wahrnehmungsformen durch eine revolutionäre Veränderung der Wahrnehmung zerstört und durch eine neue Sicht auf die Welt ersetzt wird, auf die Idee der 'apokastasis' zurückgeführt werden kann.
Der Philosoph Hent de Vries untersucht das Verhältnis von Technik und Religion in Benjamins Text "Rastelli erzählt". Im Zentrum der Interpretation steht die Erfahrung des Wunders, die Benjamin häufig in einen Zusammenhang mit technischen Apparaturen bringt. "Rastelli erzählt" behandelt das Verhältnis von Religion und Materialismus mit erzählerischen Mitteln. Die Unmöglichkeit, die Entstehung des Wunders und das Wunder selbst zu erklären, steht ihm zufolge im Zentrum von Benjamins Überzeugung, dass Religion und Materialismus sich nicht ausschließen müssen. Im Gegenteil. Vielmehr steht die Unauflösbarkeit des Wunders bei Benjamin paradigmatisch für die moderne Erfahrung von Religion, die keine Antworten mehr gibt, sondern neue Fragen aufwirft.
Despite sustained continental and national struggles for autonomy, sovereignty and independence in postcolonial Africa, the continent is increasingly embattled by the forces of globalisation which threaten African identity that is at the core of African struggles for continental and national unity. Situating the debates in the contemporary discourses on decoloniality, global consumerism, global food apartheid and the challenges and prospects of the emergent sharing economies, this book critically examines the importation, use and implications of genetically modified organisms (GMOs) and other such non-food products on African bodies, institutions and cultures. The book poses questions about how Africa can be decolonised both politically and in terms of global food apartheid and the dehumanising importation and use of 'foreign' non-food products, some of which militate against the ethos of [African] identity, Renaissance and indigeneity. On note, the book urges the African continent to ensure the safety of imports ensuing from the global flows and circulations that are mired in the resilient invisible global matrices of power.
There are milliards of off beam assumptions that Africa will always remain immobile in development of whatever type. This pseudo take has mainly been propounded by Western thinkers in order to dubiously make Africans internalise and reinforce this flimsy and flimflam dependency. Africa needs to embark on paradigm shift; and tweak and turn things around. Africa has what it take to do so quickly, especially now that new economic powers such as China and India are evolving as counterweight to the West. Shall Africa use these new economic forces to its advantage based on fair and win-win cooperation? To do so, Africa must make sure that it does not slink back into business as usual vis-a-vis beggarliness, dependence, frailty, gullibility, made-up backwardness, monkey business, and pipedreams, not to mention the nasty and narcissistic behaviours of its venal and navel-gazing rulers. Verily, Africa needs, inter alia, to use its God-given gifts, namely, immense resources, young population, abundance of vast and unexploited amounts of land. Equally, Africa must, without equivocation, invest copiously and earnestly in its people, the youth in the main. Most of all, Africa needs to shy away from all colonial carryovers and encumbrances. This volume shows many ways through and by which Africa can inverse the current imbroglio-cum-no-go it faces for the better; and thereby actualise the dream of being truly independent and prosperous.
Labour migration from Malawi to South Africa is a 'century-old phenomenon'. It dates as far back as the 1880s following the establishment of diamond and gold mines. In the period up to the 1980s, this migration took either formal or informal nature whereas in the post-1990 period it became exclusively informal, popularly known as selufu in Malawi. This book is an attempt to shed light on both forms of migration over time. By using the case of Mzimba, one of the major labour migration districts in Malawi, Perspectives of Labour Migration shows that migration, especially in the post-1990 period, remains a preoccupation of the different categories of both men and women in selected areas in the country. A cross-section of Malawians continue to regard emigration to South Africa as a means to an end: a way of fulfilling their heart-felt and life-time goals at household and societal levels. Because of their distinguished and unparalleled determination, these labour migrants continue to flock to South Africa in the midst of such challenges as xenophobia, crime, arrests and deportations. The book advances the argument that Malawian labour migrants are purposive and rational human beings who are ready to overcome these challenges, at times using the most improbable means, for example, through the use of mankhwala gha mwabi (luck medicine).

A delinquent son, a barren woman, troubled marriages, a reunion between old childhood friends, and all manner of family drama. This novel's sudden twists and turns have all the makings of a relatable African saga. Tinashe is an intelligent and vibrant young man who is sent to the city of Gweru to further his education at Midlands State University by his father. He is staying with his aunt Margaret who is always fighting with her son Cephas. Tinashe is looking forward to enjoying life and having a great time in the city but things do not seem to be in parallel with his expectations. He later realises this when he is wrongly accused of murdering his aunt, Margaret.
This project come out from our need to harness voices in Africa and Latin America, giving these voices an opportunity to converse, argue, synthesize, agree, and share ideas on the craft of writing, on life, on being and on thinking for the benefit of all. It was also an opportunity to create literary friendships and contacts between these two great regions. Generally, Latin America and Africa still have a lot of stories to share among themselves and with the rest of the world. There are still very strong untapped storytelling traditions in these continents. The stories in this volume are selected from an amazing range of entries to a call for contributions to an anthology on experimentation. It is hoped this robust selection will serve a wide variety of tastes in both Spanish and English, and that the book will open dialogue and the sharing of ideas between the two regions and the whole world. This is an invaluable contribution on many fronts.
This book critically examines the relevance of the increasingly popular theories on relationality by interfacing those theories with the African [Shona] modes of engagement known as chivanhu [often erroneously narrowly translated as tradition]. In other words, the book takes seriously concerns by African scholars that much of the theories that have been applied in Africa do not speak to relevance and faithfulness to the continent. Situated in a recent Zimbabwean context marked by multiple crises producing multiple forms of violence and want, the book examines the relevance of relational ontologies and epistemologies to the everyday life modes of engagements by villagers in a selected district. The book unflinchingly surfaces the strengths and weaknesses of popular theories while at the same time underlining the exigencies of theorising from Africa using African data as the millstones. By meticulously and painstakingly unpacking pertinent issues, the book provides unparalleled intellectual grit for the contemporary and increasingly popular discourses on (de-)coloniality and resilience in relation to the African peoples and their [often deliberately contested] environments, past, present and future. In other words, the book loudly sounds the bells for the battles to decolonise and transform Africa on Africa's own terms. This is a book that would be extremely useful to scholars, activists, theorists, policy makers and implementers as well as researchers interested not only in Africa's future trajectory but also in the simultaneities of temporalities and worlds that were sadly overshadowed by colonial epistemologies and ontologies for the past centuries.
The volume draws from René Devischs encounters with groups in southsaharan Africa, primarily. The author had the privilege to immerse himself, around the clock, in the Yakaphones activities and thoughts in southwest DR Congo from 1972 to 1974, and intermittently in Kinshasas shanty towns, from 1986 to 2003. The author first examines what sparked his choice to come to Congo, and then to pursue research among the Yakaphones in the borderland with Angola. He then invites us to follow the trajectory of his plural anthropological view on todays multicentric world. It leads us to his praise for honorary doctor Jean-Marc Elas work. He then examines the proletarian outbursts of violence that rocked Congos major cities in 1991 and 1993. These can be read as a settling of scores with the disillusioning colonial and missionary modernisation, along with president Mobutus millenarian Popular Movement of the Revolution. Furthermore, after considering the morose reduction of a major Yaka dancing mask into a mere museum-bound curio in Antwerp, the book unravels the Yakaphones perspectives on spirits and sorcerys threat. It also analyses their commitment to classical Bantu-African healing cults, along with their parallel consulting physicians and healers. By sharing the Yakaphones life-world, the analysis highlights their body-group-world weave, interlaced by the principle of co-resonance. A phenomenological and perspectivist look unfolds the local actors views, thereby disclosing the Bantu-African genius and setting for a major reversal of perspectives. Indeed, seeing 'here' from 'there' allows the author to uncover some alienating dynamics at work in his native Belgian Flemish-speaking culture. To better grasp the realm of life beyond the speakable and factual reasoning, the approach occasionally turns to the later Lacans focus on the unconscious desire, the body and its affects. The book addresses students and researchers in the humanities and, more broadly, all those immersed in the heat of the encounter with the culturally different.
Migration from Malawi to South Africa : A Historical and Cultural Novel ; Real-life Experiences
(2017)
Since the discovery and exploitation of minerals like gold, diamond and copper in South Africa, Zimbabwe and Zambia in the late nineteenth and early twentieth centuries, Malawi has played the role of a labour supplier. Malawians were attracted by the relatively higher wages obtaining in the South African mines up to the period of the decline in mine migrancy at the end of the 1980s. Following this decline, a cross-section of Malawians continued to emigrate to South Africa to seek various jobs in the burgeoning informal sector and also for trade purposes. Migration from Malawi to South Africa sheds light on the problems that labour migrants and traders encounter as they are 'toing' and 'froing' between Malawi and South Africa in pursuit of their respective goals. It shows that migration, which initially was exclusively done for wage employment, is becoming more complex by the day. This is a result of the infusion of elements of commercial migration, smuggling and human trafficking. The book advances the argument that the numbers of migrants to South Africa increased in the post-1994 period partly as a result of mal-administration by the successive democratically-elected governments in Malawi. This development weakened Malawi's otherwise promising economy and impoverished the rural masses. The book 'sees' forlorn hope in the future of labour migrants and traders, unless the Malawi Government starts to genuinely have the welfare of the populace at heart! The book is relevant and accessible to policy-makers, university and college students interested in migration studies, general readers and migrants, themselves.
This book weaves together a rich tapestry on football fandom in Zimbabwe. Based on empirical research focusing on the different dimensions of fan practices and experiences, the book is the result of multiple fieldwork processes with fans in Zimbabwe spanning a period of eight years including desk research, interviews, observation, focus group discussions and netnography. It demonstrates the nexus between social identities and supporting a sports team, highlighting that there are deeper underlying meanings and assumptions to one's support of a sporting team. Manase Chiweshe highlights the various nuances of supporting football clubs. This book provides an alternative way to understanding communities and how sport can be viewed as a serious lens into societal organisations. It offers important insights into how Zimbabweans are also engaged in leisure activities and that play is also part of their life worlds. Given the major focus on poverty, disease and conflict, African stories of intimate play and enjoyment tend to be sidelined. Soccer has the power to bring together or divide communities. In many an African context, just as in Zimbabwe, everyday ethnic and religious rivalries are played out through football matches. It is thus important to capture this space and use football as a way to heal historic and deep-seated conflicts.
This is a book on the state of social anthropology as an academic discipline in contemporary Zimbabwe. The authors are frustrated and disheartened by a problematic visibility and sluggish growth of the discipline in the country. The book makes an important claim that the future and vibrancy of anthropology in Zimbabwe, lies in how well anthropologists in the country and in the diaspora are able to join efforts in articulating, debating and enhancing its relevance and vitality. The book provides critical overview and nuanced analyses of the role and continued relevance of the discipline in reading and interpreting the social unfolding of everyday life and dynamism. It is a vital text for understanding and contextualising histories and trends in the development of social anthropology in Zimbabwe and how anthropologists in the country navigate the tumultuous waters and struggles that have engrossed the discipline since colonial times. The book has the capacity to generate added insights and influence national, continental, and global debates and trends in the field.
One of the fundamental challenges in deconstructing, rethinking and remaking the world from a Pan African vantage point is that some captives have tended to delight in the warmth of the [imperial] predator's mouth. In other words, some captives forget that the imperial predator's mouth gets warm because empire is eating and heating up from prey on the continent. (De-)Militarisation, Transnational Land Grabs and Restitution in an Age of the New Scramble for Africa: A Pan African Socio-Legal Perspective is a book that knocks on key aspects relating to land, militarisation, a PostAfrican World Order and a chaotic Post-God World Order, which require critical scholarly and policy attention in the quest to free Africa from centuries-old imperial depredations. The book carefully navigates the imperial entrapments which are designed to focus African attention only on decolonising African minds without also engaging in the [imperially more unsettling] decolonisation of African materialities.
Poverty remains a thorny and topical challenge and research topic to scholars and researchers on African development. Scholars in the Global North have since the Second World War sought to research poverty and underdevelopment in Africa, postulating what they think are the major causes of insipid and abject poverty in the continent, but with little or no success on how to solve the poverty enigma. Sadly, little research and homework have been done by scholars in context (in Africa) on why there seems to be more production rather than eradication of poverty and vulnerability in Africa and among Africans. This book is born out of the realisation for the need for both scholars on the ground and outside Africa to earnestly interrogate and reflect on the poverty situation that continues to haunt the people of Africa and rattle the conscience of the world at large. With contributors from across the continent and beyond, the volume offers a balanced and rigorous, multi-faceted analysis of Africa's poverty and vulnerability from a rich tapestry of perspectives. The volume is handy to scholars and students in the fields of African and development studies, as well as to students of Sociology, Anthropology, Political Science and Policy Studies.
African societies have rich histories, cultural heritages, knowledge systems, philosophies, and institutions that they have shaped and reshaped through history. However, the continent has been repeatedly portrayed negatively as plagued by multitudinous troubles: famine, conflict, coup, massacres, corruption, disease, illiteracy, refugees, failed state, etc. Even worse, Africans are often viewed as incapable of addressing their problems on their own. Based on such erroneous perspectives and paternalism, exogenous solutions are prescribed, out of context, for African problems. This book sheds light on the positive aspects of African reality under the key concept of 'African potentials'. It is the product of sustained consultation over a five-year period between seasoned African and Japanese anthropologists, sociologists and scholars in other areas of African studies.
Through multiple points of resistance, The Repressed Expressed underscores how hard it is to build a community in any nation with no beneficial qualities of hope and transparency. This informative collection of essays highlights that wherever stability and order are lacking, the universal appeal is to express that which is suppressed. Also, like a map or guidebook, The Repressed Expressed indicates how people in such geographical prisons strive to transform their agitation into spiritual and political pathways, free of pain and hurt from, and anger towards a dirty and corrupted world. It thus, underpins discord and brings to the fore the authority's penchant for heaping abuse upon those caused to live in fear. In short, The Repressed Expressed is an impressive compilation of literary evidence informing scholarship on opinions and beliefs relating to repression, its expression, and the immeasurable associated cost.
How come Africa is so underdeveloped when it is one of the richest continents on earth? The present volume is an attempt to theorise Africas [under-]development with a view to providing a sustainable, enduring framework of operations that will arrest the predicament of the continent while taking it forward from its current passivity. The volume rethinks and re-imagines a number of externally imposed problematic mechanisms used (un-)consciously in Africa, with the intention of raising awareness and fostering critical thinking in scholars of African development. The book is a pacesetter on how to think and research Africas [under-]development. It is also an invaluable asset for social scientists, policy makers, development practitioners, civil society activists and politicians.
At the end of his tether, Solomon Wenku contemplates a life gone awry amid widespread postcolonial squalor. Tani enters his life supposedly as a contrast to his encroaching existential gloom only to speed up the pace of his total collapse. Sanya Oshas cult novel beams a searchlight on what it feels like to survive personally and collectively in unyielding tropical malaise. This web of a narrative pits the rural versus the urban, tradition against modernity with a gallery of immortal characters and with a yearning that sings lushly of freedom.
Poetry is fragments of music thrown into the air. The primary job and aim of a poet is to create these musical notes, to play these musical notes, and the wind will take these fragment notes, sounds, musics into the ears of listeners. Zimbolicious Poetry Anthology, Volume 2 is one of those winds among many others. As we all are aware of, when the wind travels it has no boundaries, it collects, it deposits, it mixes things up; you never know where that leaf you see the wind carrying will eventually be deposited, is there another wind, another element that is going to move that leaf to another place... We firmly believe it is a good wind. It will be able to push our poetry making in Zimbabwe into other frontiers. Zimbolicious Poetry Anthology, Volume 2 continues from where we left off with the first Zimbolicious Poetry Anthology we created in 2016. In this Volume 2, we have 77 poems from 30 poets and translators, which include among others; experienced poets, academic poets, street poets, emergent poets, beginning poets, all telling stories associated with what all these poets refer to as home, that is, Zimbabwe. It is an ongoing debate on what is Zimbabwe, what we want our Zimbabwe to be socially, culturally, politically, thus we allowed every opinion space in this anthology, whether us editors agree with them or not. We have poets tackling issues to do with poetry, writing in general, art, place, identity, tradition, struggle, culture, gender, collective understanding, religion, individual, human rights and love, among others.
'Magnus Opus: A Tribute to Ntarikon is a scathing indictment of the political status quo in the Republic of Cameroon where the ruling party, the Cameroon People's Democratic Movement (CPDM), rides roughshod over the populace. In this long poem, Vakunta cries out poignantly against social dystopia and the deplorable moments lived by members of the Social Democratic Front (SDF) at Ntarikon Park on May 26, 1990. One cannot read this poem without feeling the despair and helplessness experienced by members of this political party as they were maimed, killed and reminded that the future holds no good for them. The prosody and semantics of the poem amplify the ontological angst experienced by Cameroonians on a daily basis.'

This book is a pacesetter in matters of mining and the environment in Africa from multidisciplinary and spatio-temporal perspectives. The book approaches mining from the perspectives of law, politics, archaeology, anthropology, African studies, geography, human ecology, sociology, history, economics and development. It interrogates mining and environment from the perspectives of customary law as well as from the perspectives of Euro-modern laws. In this sense, the book straddles precolonial, colonial and postcolonial mining and environmental perspectives. In all this, it maintains a Pan-Africanist perspective that also speaks to contemporary debates on African Renaissance and to the unity of Africa. From scrutinising the lived realities of African miners who are often insensitively and unjustly addressed as illegal miners, the book also interrogates transnational mining corporations; matters of corporate social responsibility as well as matters of tax evasions by transnational corporations whose commitment to accountability to African governments is questioned. With both theoretical chapters and chapter based on empirical studies on mining and the environment across the African continent, the book provides a much needed holistic, one stop shop for scholars, activists, researchers and policy makers who need a comprehensive treatise on African mining and the environment. The book comes at the right time when matters of African mining and environment are increasingly coming to the fore in the light of discourses about the new 21st century scramble for African resources, in which big transnational corporations and nations are jostling to suck Africa dry in their race to control planetary resources. It is a book that speaks to contemporary broader issues of (de-)coloniality and transformation of African minds and African environmental resources.
Contemporary scholarly discourses about decolonising materialities are taking two noticeable trajectories, the first trajectory privileges establishing connections, relationships and associations between human beings and nature. The second trajectory privileges restoration, restitution, reparations for colonial dispossessions, lootings and disinheritance. While the first trajectory presupposes that colonialism was merely about separation, alienation, and disconnections between human beings and nature, the second trajectory stresses the colonialists dispossession, disinheritance and privations of Africans. Drawing on contemporary discourses about materialities in relation to semiotics, (non-)representationalism, rhetoric, ecocriticism, territorialisation, deterritorialisation and reterritorialisation, translation, animism, science and technology studies, this book teases out the intellectually rutted terrain of African materialities. It argues that in a world of increasing impoverishment, the significance of materialities cannot be overemphasised: more so for the continent of Africa where impoverishment materialises in the midst of resource opulence. The book is a pacesetter in no holds barred interrogation of African materialities.
For centuries the continent of Africa has been characterised by negative images such as poverty, disease and conflicts. Today, however, the People's Republic of China's growing presence in Africa, particularly with regards to China-Africa business relations, brings new vitality to the continent. This new movement is not a windfall but rather obtained through the hard work of both African and Chinese people at various levels. Narrating on daily experiences of Chinese merchants and their vivid interactions with people in Botswana, this book decodes the frustrating while rewarding process through which China-Africa relations have been maturing on the grass-roots level. This book not only presents insights and suggestions to both Botswana and Chinese policy makers interested in understanding their constituents' everyday interactions with each other, but also offers readers interested more broadly in contemporary Chinese experiences in Africa a fascinating glimpse into these cross-cultural encounters. This book is an original and pioneering study of issues that resonate in almost every African country which has responded to a growing Chinese presence. It argues that as the process of globalisation permeates the everyday lives of people, each individual is empowered to be an 'ambassador' in shaping international relations.
The book examines the nexus between youth conflict and the occult drawing its insights from the oil-rich Niger Delta of Nigeria. It sees the occult represented by the Egbesu deity in this conflict as a form of religious belief imbued in this case with the powers of good. Thus, the religious occult is regenerated and re-energised as an idiom of justice and fairness within the Nigerian state by militant youth fighting the forces of the Nigerian state. Ingeniously, the young men simply dug into the cultural repertoire of the people for a hitherto popular expression of justice and perceived source of potency which they felt would not only provide spiritual protection but also pander to the popular imagination of justice. Even against the background prevalent Christianity, the Egbesu does not generate tension in beliefs but responds to the critical exigency of the immediate socio-political milieu of the people.
It Does Matter To Listen is a collection of short anecdotal pieces of writings, spanning different subject areas - including politics, leadership and management - with the purpose of counselling and edifying the present and future generations. It is a must-read for anyone interested in how to go about business in everyday life, at home, at work and during leisure.
In this collection, Doh straddles the Atlantic with voices that doubt, question, and lament the black predicament; voices that evoke the wisdom of Africa's cultural values in a manner reminiscent of the continent's orality. Like the echoing of the talking drums in the forests and the savannahs, these voices acknowledge the challenges and vexing truths of the hour: the plight of a people that have been buffeted repeatedly by waves of invasion, deceit, and betrayals, yet against which onslaught they remain standing, frighteningly tall in dignity and integrity.
In view of the resilience of Africa's underdevelopment, what do Africans make of their determined aspirations for development? The continent of Africa has constantly drawn global attention, most especially for both human and natural evils. Underdevelopment, it appears, is one of the most eminent threatening evils. It has plunged and promises to maintain the majority of Africa in abject poverty, insecurity, and vulnerability. What perpetuates the ghost and gory of underdevelopment in Africa, despite a proliferation of development rhetoric and initiatives? How do ordinary Africans react to repeated talk and claims of development with little evidence of transformation for the better in their material circumstances? This book interrogates the tenacity of underdevelopment amid calls for Africa to rise from its slumber and reclaim its position in global affairs as the mother continent of humankind. It contributes to the ongoing debates on why Africa remains trapped in the clutch of underdevelopment many decades after the purported end of colonialism. The book comes at a critical time in human history; a time when the talk on Africa's [under-]development is louder due to the ravages of economic downturns and dysfunctional conflicts. It poses a challenge to development practitioners, civil society activists, statesmen, economists, political scientists and theorists to rethink and reconsider their role as technocrats, experts and ambassadors of positive change in Africa and the world beyond.
How really worth are the African endogenous knowledge and know-how? Why and how can we promote this inheritage, while the so-called western scientific model looks like the best means of knowing and mastering the world? This book answers these questions by examining ifa, a West-African system of knowledge and practices which a narrow knowledge reduces to a fanciful divinatory art, an art then logically 'perceived as inconsistent and theoretically useless'. Yet, more than a divinatory art, ifa, when we submit it to analysis, appears to be an organized set of knowledge and researches, a science in the making. What makes us really think that way is the intellectual vocation that defines ifa, the rigor of the logical operations that it implies and which recalls in one way or the other the game of implicit mathematics, the objectivity requirement which is valued by the actors of the system and rests on a genuine critical tradition. This opinion is also based on the weight of myths upon which ifa rests and which constitute an important granary where a prominent set of knowledge is packed. Beyond the establishment of the consistency and the limitations of ifa, this book has strived to define a 'method' of examination and validation of the knowledge which has emerged out of the official scientific system. In fact, the questions which arise from it are finally intended to give a new foundation to philosophy of sciences and to epistemology.
