U ovome se radu obrađuju naglasne značajke u govorima i toponimiji Zažablja i Popova. U prvome se dijelu rada iznose bitne fonološke, morfološke, sintaktičke i leksičke značajke obrađenoga područja te ga se uspoređuje s drugim štokavskim govorima. U središnjemu se dijelu rada obrađuju mjesne naglasne osobitosti, primjerice naglašivanje starih i suvremenih posuđenica, razlikovna uloga naglaska te odrazi praslavenskih naglasnih paradigma. U završnome se dijelu iznose i neke naglasne razlike u mjesnim govorima, poglavito s obzirom na narodnosnu pripadnost.
U ovome radu autor će, na osnovu vlastitih istraživanja, pokušati dati sumaran prikaz akcenatskih svojstava govora otoka Iža, smještenog u zadarskom arhipelagu. Namjera mu je smjestiti iški govor i akcenatski sustav među drugim čakavskim otočkim govorima, dati fonetski i fonološki opis pojedinih akcenata i potkrijepiti ih primjerima koje je čuo od iških govornika i, konačno, pokušati utvrditi fonološki status čakavskog akuta u iškome govoru. Budući da su istraživanja bila ograničenoga karaktera, ovaj rad nije zamišljen kao konačan opis, već kao polažišna točka za buduća istraživanja koja je potrebno izvršiti na osnovu kojih će se moći napraviti što iscrpniji i potpuniji opis iškoga govora i akcenatskoga sustava.
U članku je riječ o sklonidbi i naglasku imenica srednjega roda o-sklonidbe u mjesnom govoru sela Jevšček pokraj Livka (općina Kobarid, Slovenija), koji pripada nadiškomu dijalektu slovenskoga, i to sa sinkronijskoga i dijakronijskoga aspekta. S aspekta jezikoslovnoga opisa prikazani su nastavci i njihova distribucija s obzirom na osnovu te naglasni tipovi i njihove paradigme. U jezičnopovijesnome dijelu određuje se povijesni izvod pojedinih nastavaka i naglasnih tipova. Opisani oblici i naglasni sustav postavljaju se u širi slovenski i slavenski kontekst.
The article analyzes the accentuation of western South Slavic l-participles of verbal stems ending in an occlusive that are formed by adding the formant *-l- directly to the stem, e.g. *nes-lъ, Croatian nȅsao, Slovene nesel. Data from Slovene, Čakavian, Kajkavian and Štokavian dialects are compared and discussed against the background of late Proto-Slavic and early dialectal accentual and phonological changes. The operation of accentological changes such as Dybo’s law, Stang’s law and the rise of the neocircumflex, as well as the reduction of weak jers caused alternations in tone, vowel-length and position of the ictus. These alterations could be analogically eliminated or extended at different times and in different areas during the linguistic history of western South Slavic, thus causing the rise of some of the earliest isoglosses in the area in which western South Slavic is spoken.
Ovaj rad predstavit će akcentuaciju, podrijetlo i distribuciju naglasaka u kajkavskim govorima istočne ludbreške Podravine. Prozodija ludbreških govora naselja istočno od Ludbrega, u smjeru Ludbreg – Legrad, nije prikazana u dosadašnjim istraživanjima mjesnih govora toga kraja pa je cilj ovoga rada opisati sadašnje stanje koje se zbog utjecaja medija i migracija stanovništva mijenja, a jedna od očekivanih promjena u razvoju fonoloških sustava mjesnih govora gubljenje je oprjeke po kvantiteti. Istraživanja će se nadovezati na dosad provedena istraživanja fonoloških sustava govora ludbreške Podravine.
Tema članka je naglasak i-glagolâ u govoru mjesta Banjole (oko 6 km južno od Pule), koji pripada premanturskoj skupini govorâ jugozapadnoga istarskog dijalekta. Ta je skupina govora zanimljiva jer se odlikuje nekim obilježjima tipičnima za štokavsko narječje (npr. nastavak -ā u Gmn.) te vjerojatno predstavlja ostatak prijelaznih južnočakavsko-zapadnoštokavskih govora, donesen u Istru tijekom seobâ u 16. i 17. st. Naglasni se sustav tih govora i u općim crtama donekle razlikuje od onoga ostalih JZ istarskih govora; npr. naglasak se tu povlači na prethodni slog u većem broju okolinâ, čuva se preskakanje naglaska na prednaglasnice i sl., zbog čega se oni, uz ostalo, i svrstavaju u zasebnu skupinu.
Kada je riječ o naglasku i-glagolâ, stanje je u raznim slavenskim govorima raznoliko i složeno. Opis situacije u govoru Banjolâ dopunit će sliku dobivenu istraživanjima drugih slavenskih govorâ te pripomoći rekonstrukciji naglaska toga glagolskog tipa u općeslavenskom.
U članku se opisuje naglasak imenica u govoru mjesta Kali na otoku Ugljanu.

Franz Kafkas Äußerungen zu seiner angeblichen Unmusikalität sind in der Kafka-Forschung hinlänglich bekannt. Weniger erforscht ist, wie diese spezifische Unmusikalität mit Kafkas poetologischem Konzept zu vereinen ist. Die Auffassung von Musik in seinen Texten, wie zum Beispiel in 'Josefine, die Sängerin' oder 'Das Volk der Mäuse', im Schluss des Romanfragments 'Der Verschollene' und in seinen Briefen und Tagebucheintragungen, verdeutlicht, dass er ein ganz anderes Verständnis von Musik hatte als etwa sein musikalischer Freund Max Brod. Vor dem Hintergrund von Brods Übersetzungsarbeit am Libretto von Leoš Janáčeks 'Jenůfa (Ihre Ziehtochter)' und von der Einführung der Oper auf die internationale Szene wird ein Zusammenhang zwischen Musikalität und Kafkas Auffassung von Literatur hergestellt.
Noch vor 1900 wurde der Begriff 'Hermetismus' aus den spätantiken Geheimlehren auf die Literatur übertragen - um bald danach in der sog. hermetischen Lyrik eine negative Etikettierung zu erhalten. Vor allem die Dichter, die sich einer Poetik der Unverständlichkeit bedient haben, wurden somit kritisiert und zurückgewiesen. Dabei wurde oft übersehen, dass diese Unverständlichkeit keineswegs eine eitle Machart selbstbewusster Dichter war, sondern eine innere Notwendigkeit. Am Beispiel dessen, wie Paul Celan (1920–1970) und Nelly Sachs (1891–1970) die Shoah lyrisch verarbeiteten, sollen Gründe für die Wahl der hermetischen Ausdrucksweise gefunden werden: eine zu komplexe und widersprüchliche Wirklichkeit, die Angst vor der Gefährdung durch eine verständliche Aussage oder die Entscheidung für das 'offene Kunstwerk' mit beliebig vielen möglichen Interpretationen.
"wir haben ein land aus worten." In Semier Insayif Roman 'Faruq' (2009) geht es um Worte und Erinnerungen, um das (Nicht-)Sprechen-Können und darum, Sprache und Gedächtnis zu verlieren. Es geht um das Schreiben, Sprechen und Rezitieren im Bereich des Dazwischen von Sprachen und Kulturen. Ausgehend von der Perspektive des Ich-Erzählers im Text entfalten sich die Nuancen und Facetten des Lebens als Geschichten, als Texturen der Erinnerung und als eine Art Sprach- und Klanggewebe. Bezugnehmend auf eben diese poetischen und rhetorischen Aspekte des Textes wird eine Lektüre unternommen, die auf postkolonialen und dekonstruktiven Ansätzen wie auch auf Gedächtnistheorien basiert. Die Lektüre versucht sowohl auf die Anforderungen und Besonderheiten des Textes in allen Facetten des Dazwischens zu reagieren als auch jene Perspektiven zu ergründen, die für die zeitgenössische Entwicklung der sogenannten Migrationsliteratur signifikant sind.
Angekommensein ist Unterwegssein : zur Neudeutung der Begriffe 'Flucht' und 'Wohnen' bei Fred Wander
(2014)
Der Aufsatz untersucht die literarisch-philosophischen Voraussetzungen von Fred Wanders Prosaschriften, insbesondere seinen Hotelromanen. Ausgangspunkt des Beitrags ist Wanders Autobiographie 'Das gute Leben' (2006), mit besonderem Augenmerk auf das Adjektiv 'gut' und dessen kontextueller Bedeutung. Sein Verständnis von 'gut' weist auf die Notwendigkeit einer neuen Ethik für die Überlebenden des Naziterrors hin, die sich teils mit Adornos Ethik-Begriff der 'Minima Moralia', teils mit Heideggers Kritik des Humanismus deckt. Vor allem die Begriffe 'Flucht' und 'Wohnen' - bei Wander jeweils als 'gelassenes Ausweichen' ebenso als 'Haus-Hotel-Metapher' dargestellt - tragen zu einer neuen Bestimmung von Wanders Ethik-Begriff bei, die allen Menschen helfen soll, vergangenes und gegenwärtiges Unheil zu überleben.
Die Feminisierung der Migration ist trotz ihrer verspäteten öffentlichen Wahrnehmung kein neues Phänomen: Seit den Anfängen der Arbeitsmigration immigrierten Frauen nicht nur als 'Anhängsel' ihrer Männer, sondern auch selbständig in die deutschsprachigen Länder. In der Öffentlichkeit werden sie bis heute, von stereotypen medialen Zerrbildern beeinflusst, als Opfer wahrgenommen, als die fremde Frau, die sprach- und chancenlos ist. Der Beitrag untersucht vor diesem Hintergrund und am Beispiel von Julya Rabinowichs Roman 'Die Erdfresserin' (2012) die weibliche Identitätssuche unter den Bedingungen der nicht-privilegierten Formen der Migration nach Österreich und im Spannungsfeld von Ethnizität, Kultur, Geschlecht und Klasse.
Der Beitrag widmet sich den genderspezifischen Aspekten angesichts des Terrors und Totalitarismus in den Romanen 'Studenten, Liebe, Tscheka und Tod' (1931) von Alja Rachmanowa und 'Spaltkopf' (2008) von Julya Rabinowich. Anhand zweier Figuren - Griselda Nikolajewna (Rachmanowa) und Ada/Rahel (Rabinowich) - werden ganz unterschiedliche Verhaltensmuster weiblicher Gewaltopfer aufgezeigt: politische Verblendung und krankhaftes Morden, also Gewalt gegen andere (Griselda Nikolajewna) und Scham, Verdrängung und Verfälschung der eigenen Identität - Gewalt gegen sich selbst (Ada/Rahel). Von zentraler Bedeutung ist dabei die von beiden Frauen geteilte Gewalterfahrung in der Begegnung mit dem Fremden: Während Griselda Nikolajewna von ihrem chinesischen Ehemann misshandelt und halbtot verprügelt wurde, musste das kleine jüdische Mädchen Rahel zuschauen, wie sein Vater von Antisemiten umgebracht wurde.
Dieser Beitrag setzt sich mit der wenig bekannten Schriftstellerin Viktorija Kocman und ihrem Werk auseinander. Kocman gehört zur jüngeren Generation der auf Deutsch schreibenden ImmigrantInnen aus dem ehemaligen Jugoslawien. Die gebürtige Belgraderin beschäftigt sich in ihren Texten mit Migration und den Jugoslawienkriegen. Der Aufsatz gliedert sich in drei Teile: Der erste Teil stellt mit einem Fokus auf die eigenen Erfahrungen der Migration und des Sprachwechsels die Autorin vor. Im darauffolgenden Teil werden die einzelnen Publikationen in chronologischer Reihenfolge kurz präsentiert, kategorisiert sowie Kocman im literarischen Feld positioniert. Der abschließende Teil nimmt eine thematische Analyse des Werkganzen vor, wobei das entworfene Wien-Bild, die Ost-West-Dichotomie, das Thema der Zugehörigkeit sowie der Umgang mit dem Fremden hinsichtlich des Eigenen untersucht werden.
Dieser Beitrag stellt das sowohl auf Serbisch als auch auf Deutsch verfasste Werk von Ivan Ivanji vor und bezieht es auf Fragestellungen zur trans- bzw. interkulturellen Literatur. Als Schwerpunkt dabei wird die Konstruktion von kultureller Identität untersucht, die seinem Werk zugrunde liegt. Ivanji zeichnet ein transkulturelles Bild seiner Herkunftsregion Banat und thematisiert Mehrsprachigkeit als Normalität. Doch das Werk entzieht sich weitgehend einer Einordnung in Kategorien der sogenannten Migrations- bzw. interkulturellen Literatur. Nicht einmal eindeutig beantwortet werden kann, ob Ivanji in seiner Muttersprache schreibt. Die Texte verzichten auf eine verfremdende Einarbeitung der Mehrsprachigkeit und auf Distanz zur und Brüchen mit der deutschen literarischen Tradition. Manche Schwierigkeiten der Begrifflichkeiten und Kategorien wie 'Migrations-' oder 'interkulturelle Literatur' können so mit einer Betrachtung von Ivanjis Werk sichtbar gemacht werden.
Spätestens im Zuge der postkolonialen Theorie wurde auch in den Literaturwissenschaften eine Sichtweise auf Interkulturalität etabliert, die sich von Essentialismen und Dichotomien verabschiedet hat und kulturelle Identität nicht als starres Konstrukt, sondern allenfalls als das vorübergehende Resultat beständiger Prozesse des Aushandelns und der selektiven Aneignung versteht. Ort dieser Aushandlung ist nach Homi K. Bhabha der dritte Raum (third space), der als Schwellenraum zwischen Identität und Differenz gegen die Vorstellung scharf gezogener Grenzen opponiert. Im vorliegenden Beitrag wird der Versuch unternommen, die vielfältigen Motive und Strukturelemente des Hybriden und Monströsen im Roman 'Terminifera' (2007) von Michael Stavarič im Kontext neuerer Ansätze der Interkulturalitätsforschung als Zeichen individueller Identitätsbildung jenseits binärer Ordnungssysteme (neu) zu interpretieren.

Anhand von zwei auf Deutsch verfassten essayistischen Texten von Jiří Gruša - 'Beneš als Österreicher' (2012) und 'Die Gebrauchsanweisung für Tschechien und Prag' (2003) - wird gezeigt, wie die Konzepte von Nationalgeschichte und Nationalliteratur an ihre Grenzen gebracht werden können: Durch vervielfältigende, ironisierende und verdichtende Verfahren werden nationale Selbst-Behauptungen entstellt, sowie die Konstitution und Funktion kollektiver Identitätsnarrative ausgestellt. Während in der Gebrauchsanweisung ausgerechnet ein 'pluralis nationalis' die Selbstvergewisserungen subvertiert, zeigt sich im bzw. durch den Beneš-Essay, wie die Erzählungen der Figur Beneš die Geister der Nation scheiden. Insofern werden die beiden Texte als Beispiele dafür gelesen, wie durch Schreibstrategien, aber auch angesichts editionsgeschichtlicher Zusammenhänge sowie im Hinblick auf die Rezeption eindeutige Zuweisungen zu einer Nationalliteratur oder Nationalgeschichte in Frage gestellt werden.
Background & Aims: Simeprevir is an oral, once-daily inhibitor of hepatitis c virus (HCV) protease NS3/4A. We investigated the safety and efficacy of simeprevir with peg-interferon α-2a and ribavirin (PR) in a randomized, double-blind, placebo-controlled, phase 3 trial of patients with HCV genotype 1 infection who relapsed after previous interferon-based therapy.
Methods: Patients were assigned randomly (2:1) to groups given simeprevir (150 mg, once daily) and PR (n = 260) or placebo and PR (n = 133) for 12 weeks. Patients then were given PR alone for 12 or 36 weeks (simeprevir group, based on response-guided therapy criteria) or 36 weeks (placebo group).
Results: Simeprevir and PR was significantly superior to placebo and PR; rates of sustained virologic response 12 weeks after planned end of treatment (SVR12) were 79.2% vs 36.1%, respectively (43.8% difference; 95% confidence interval, 34.6–53.0; P < .001). Among patients given simeprevir, 92.7% met the response-guided therapy criteria and were eligible to complete PR at week 24; of these, 83.0% achieved SVR12. HCV RNA was undetectable at week 4 in 77.2% of patients given simeprevir and 3.1% given placebo. On-treatment failure and relapse rates were lower among patients given simeprevir and PR than those given placebo and PR (3.1% vs 27.1%, and 18.5% vs 48.4%, respectively). Patients given simeprevir did not have adverse events beyond those that occurred in patients given PR alone. Most adverse events were grades 1/2; the prevalence of anemia and rash was similar in both groups. Patients in both groups reported similar severity of fatigue and functional impairments during the study, but duration was reduced among patients given simeprevir.
Conclusions: In a phase 3 trial of patients who had relapsed after interferon-based therapy, the addition of simeprevir to PR was generally well tolerated, with an SVR12 rate of 79.2%. Most patients (92.7%) receiving simeprevir were able to shorten therapy to 24 weeks. ClinicalTrials.gov number: NCT01281839.
In many markets, design is one of the key factors in determining a product’s success. The present research offers insights into the role of design for the success of cars, and offers procedures to measure the quality of the designs objectively. The authors show that visual design plays a major role in a product’s success in the automobile market. In the study, two visual design aspects were already sufficient to significantly improve traditional sales forecasting models for cars. Visual prototypicality and visual complexity both had a positive impact on sales, and designs that were perceived as both prototypical and complex were the ones that displayed the best results. Most design evaluation used to be based on subjective measures, but the researcher applied a new, objective procedure to measure prototypicality and complexity. While the latter was detected by the disk space needed by the compressed image file, the new approach for measuring prototypicality was even more sophisticated. It relied on the technique of image morphing. Morphing is a technique that allows the construction of a visual synthesis – or average picture – from a number of individual pictures. Once a car morph is developed, one can determine the visual similarity of different car models to the morph in order to obtain its prototypicality. In principle, this procedure can be automated completely, and including a large number of versions is possible. These measures therefore seem suitable for supporting design decision processes in practice.
OBJECTIVES: Outcome of aortic valve replacement may be influenced by the choice of bioprosthesis. Pericardial heart valves are described to have a favourable haemodynamic profile compared with porcine valves, although the clinical notability of this finding is still controversially debated. Herein, we compared the long-term results of two commonly implanted bioprosthesis at a single centre.
METHODS: All consecutive patients undergoing isolated aortic valve replacement with either a Carpentier-Edwards Magna pericardial prosthesis or a Medtronic Mosaic porcine prosthesis between 2002 and 2008 were analysed regarding preoperative characteristics, short- and long-term survival, valve-related complications and echocardiographic findings.
RESULTS: The Medtronic Mosaic was implanted in 163 patients and the Carpentier-Edwards Magna in 295 patients. The sizes of implanted valves were 22.4 ± 1.5 mm for the Mosaic and 21.8 ± 1.8 mm for the Magna (P = 0.001). The long-term survival rate was 76 and 56% after 5 and 10 years for the Medtronic Mosaic, which was comparable with the Carpentier-Edwards Magna (77 and 57%; P = 0.92). Overall long-term survival was comparable with an age- and sex-matched Austrian general population for both groups. Valve-related adverse events were similar between groups. The postoperative mean transvalvular gradient was significantly increased in the Mosaic group (24 ± 9 mmHg vs 17 ± 7 mmHg; P < 0.001).
CONCLUSIONS: Both types of aortic bioprostheses offer excellent results after isolated aortic valve replacement. Despite relevant differences in gradients, long-term survival was comparable with the expected normal survival for both bioprostheses. Patients with a porcine heart valve had a higher postoperative transvalvular gradient.
The paper is aimed at contributing to an empirically grounded understanding of the psychosocial dynamics that underlie the relation between heteronormative images of masculinity, internalized heterosexism and health behavior of gay men in the global North. It is based on a qualitative interview study that focuses on the consequences of the internalization of dominant images of masculinity for the identity constructions of gay men and their HIV-related sexual risk behavior in Germany. In the paper it will be argued that 1) the tension between the authoritative image of masculinity that is determined by heteronormative discourses one the one hand and the gendered self-image that is shaped and threatened by connotations of a non-masculine homosexuality on the other constitutes a decisive issue of gay identity constructions, 2) a higher sexual risk behavior can be understood as a possible consequence of the internalization of masculine images and its impact on the self-esteem, if the self-image does not match the male ideal, and 3) this may include a paradoxical desire for the imagined masculinity that is experienced as violent with regard to one’s own psychodynamics. Finally, perspectives on gay masculinities that may transgress dominant heteronormative modes of subjectification are discussed.
CD4+CD25+ regulatory T cells (Tregs) represent a specialized subpopulation of T cells, which are essential for maintaining peripheral tolerance and preventing autoimmunity. The immunomodulatory effects of Tregs depend on their activation status. Here we show that, in contrast to conventional anti-CD4 monoclonal antibodies (mAbs), the humanized CD4-specific monoclonal antibody tregalizumab (BT-061) is able to selectively activate the suppressive properties of Tregs in vitro. BT-061 activates Tregs by binding to CD4 and activation of signaling downstream pathways. The specific functionality of BT-061 may be explained by the recognition of a unique, conformational epitope on domain 2 of the CD4 molecule that is not recognized by other anti-CD4 mAbs. We found that, due to this special epitope binding, BT-061 induces a unique phosphorylation of T-cell receptor complex-associated signaling molecules. This is sufficient to activate the function of Tregs without activating effector T cells. Furthermore, BT-061 does not induce the release of pro-inflammatory cytokines. These results demonstrate that BT-061 stimulation via the CD4 receptor is able to induce T-cell receptor-independent activation of Tregs. Selective activation of Tregs via CD4 is a promising approach for the treatment of autoimmune diseases where insufficient Treg activity has been described. Clinical investigation of this new approach is currently ongoing.
Brain activity reveals exquisite coordination across spatial scales, from local microcircuits to brain-wide networks. Understanding how the brain represents, transforms and communicates information requires simultaneous recordings from distributed nodes of whole brain networks with single-cell resolution. Realizing multi-site recordings from communicating populations is hampered by the need to isolate clusters of interacting cells, often on a day-to-day basis. Chronic implantation of multi-electrode arrays allows long-term tracking of activity. Lithography on thin films provides a means to produce arrays of variable resolution, a high degree of flexibility, and minimal tissue displacement. Sequential application of surface arrays to monitor activity across brain-wide networks and subsequent implantation of laminar arrays to target specific populations enables continual refinement of spatial scale while maintaining coverage.
Generating functionals may guide the evolution of a dynamical system and constitute a possible route for handling the complexity of neural networks as relevant for computational intelligence.We propose and explore a new objective function, which allows to obtain plasticity rules for the afferent synaptic weights. The adaption rules are Hebbian, self-limiting, and result from the minimization of the Fisher information with respect to the synaptic flux. We perform a series of simulations examining the behavior of the new learning rules in various circumstances.The vector of synaptic weights aligns with the principal direction of input activities, whenever one is present. A linear discrimination is performed when there are two or more principal directions; directions having bimodal firing-rate distributions, being characterized by a negative excess kurtosis, are preferred. We find robust performance and full homeostatic adaption of the synaptic weights results as a by-product of the synaptic flux minimization. This self-limiting behavior allows for stable online learning for arbitrary durations.The neuron acquires new information when the statistics of input activities is changed at a certain point of the simulation, showing however, a distinct resilience to unlearn previously acquired knowledge. Learning is fast when starting with randomly drawn synaptic weights and substantially slower when the synaptic weights are already fully adapted.
Polo-like kinase 1 regulates the stability of the mitotic centromere-associated kinesin in mitosis
(2014)
Proper bi-orientation of chromosomes is critical for the accurate segregation of chromosomes in mitosis. A key regulator of this process is MCAK, the mitotic centromere-associated kinesin. During mitosis the activity and localization of MCAK are regulated by mitotic key kinases including Plk1 and Aurora B. We show here that S621 in the MCAK’s C-terminal domain is the major phosphorylation site for Plk1. This phosphorylation regulates MCAK’s stability and facilitates its recognition by the ubiquitin/proteasome dependent APC/CCdc20 pathway leading to its D-box dependent degradation in mitosis. While phosphorylation of S621 does not directly affect its microtubule depolymerising activity, loss of Plk1 phosphorylation on S621 indirectly enhances its depolymerization activity in vivo by stabilizing MCAK, leading to an increased level of protein. Interfering with phosphorylation at S621 causes spindle formation defects and chromosome misalignments. Therefore, this study suggests a new mechanism by which Plk1 regulates MCAK: by regulating its degradation and hence controlling its turnover in mitosis.
Global Governance ist in: Klingt neuartig, global ist eigentlich auch alles und wer will sich schon vorwerfen lassen, noch im „methodologischen Nationalismus“ verhaftet zu sein? Dies ist überspitzt formuliert, doch wie sich zeigte nicht ganz unberechtigt. Nichtsdestotrotz waren die OrganisatorInnen des ersten Weltkongresses der International Association of Political Science Students (IAPSS) wohl selbst überrascht als zur Tagung mit dem Titel „The Limits of Global Governance“ rund 200 Anmeldungen von Studierenden kamen. In Thessaloniki, der europäischen Jugendhauptstadt 2014, wurde vier Tage über Global Governance debattiert und in den insgesamt sieben studentischen Panels, zahlreichen Vorträgen von etablierten WissenschaftlerInnen und weiteren Veranstaltungen zeigte sich vor allem die Vielfalt und Breite des Themas. Wir werden daher im Folgenden Schlaglichter auf interessante Veranstaltungen und Inhalte werfen und abschließend ein kritisch-konstruktives Fazit der Tagung ziehen.
Objective: To investigate the impact of HPV status in patients with locally advanced head and neck squamous cell carcinoma (HNSCC), who received surgery and cisplatin-based postoperative radiochemotherapy.
Materials and methods: For 221 patients with locally advanced squamous cell carcinoma of the hypopharynx, oropharynx or oral cavity treated at the 8 partner sites of the German Cancer Consortium, the impact of HPV DNA, p16 overexpression and p53 expression on outcome were retrospectively analysed. The primary endpoint was loco-regional tumour control; secondary endpoints were distant metastases and overall survival.
Results: In the total patient population, univariate analyses revealed a significant impact of HPV16 DNA positivity, p16 overexpression, p53 positivity and tumour site on loco-regional tumour control. Multivariate analysis stratified for tumour site showed that positive HPV 16 DNA status correlated with loco-regional tumour control in patients with oropharyngeal carcinoma (p = 0.02) but not in the oral cavity carcinoma group. Multivariate evaluation of the secondary endpoints in the total population revealed a significant association of HPV16 DNA positivity with overall survival (p < 0.01) but not with distant metastases.
Conclusions: HPV16 DNA status appears to be a strong prognosticator of loco-regional tumour control after postoperative cisplatin-based radiochemotherapy of locally advanced oropharyngeal carcinoma and is now being explored in a prospective validation trial.
Late stage cancer is often associated with reduced immune recognition and a highly immunosuppressive tumor microenvironment. The presence of tumor infiltrating lymphocytes (TILs) and specific gene-signatures prior to treatment are linked to good prognosis, while the opposite is true for extensive immunosuppression. The use of adenoviruses as cancer vaccines is a form of active immunotherapy to initialise a tumor-specific immune response that targets the patient’s unique tumor antigen repertoire. We report a case of a 68-year-old male with asbestos-related malignant pleural mesothelioma who was treated in a Phase I study with a granulocyte-macrophage colony‑stimulating factor (GM-CSF)-expressing oncolytic adenovirus, Ad5/3-D24-GMCSF (ONCOS-102). The treatment resulted in prominent infiltration of CD8C lymphocytes to tumor, marked induction of systemic antitumor CD8C T-cells and induction of Th1- type polarization in the tumor. These results indicate that ONCOS-102 treatment sensitizes tumors to other immunotherapies by inducing a T-cell positive phenotype to an initially T-cell negative tumor.
"Kapabel, miserabel, aimabel" : Funktionen der französischen Sprachelemente in Heinrich Heines Lyrik
(2014)
Durch das gesamte Werk Heinrich Heines ziehen sich fremdsprachige Einstreuungen, wobei diejenigen in französischer Sprache das größte Gewicht einnehmen. Nach einem Rekurs auf Heines biographische Situation und sein Verhältnis zur deutschen und französischen Sprache werden Form und Funktion der französischen Einsprengsel – vor allem Adjektive, substantivierte Verben und Interjektionen – in Heines lyrischen Texten untersucht. Anhand zahlreicher Beispiele zeigt der Beitrag, dass die französischen Elemente offensichtlich bewusst eingesetzt wurden, um bestimmte semantische Strategien zu verfolgen. Dabei können vor allem sprach-spielerische und gesellschaftskritische Funktionen nachgewiesen werden.
Response to Kriticos et al.
(2014)
Various aspects of uncertainty have become topical in pest risk modelling discussions. A recent contribution to the literature sought to explore the effect of taxonomic uncertainty on modelled pest risk. The case study involved a high profile plant pathogen Puccinia psidii, which causes a major disease of plants within the Myrtaceae family. Consequently, the results and recommendations may attract a wide range of interest in the biosecurity and pest risk modelling communities. We found the study by Elith et al. (2013) included a number of methodological issues that limit some of the specific and general conclusions reached in the paper. We discuss these issues and the ensuing implications for biosecurity management. We also draw attention to the need for pest risk modellers and biosecurity managers to find ways to communicate more effectively. We urge modellers and managers alike to develop a better understanding of the challenges and limitations of modelling species potential distributions across novel climates, and to be able to appreciate the meanings and limitations of models framed in different ways.
This dataset represents a registry of species that are not native but recorded to live in the wild of at least one of the four countries that comprise the Two Seas Area, i.e. Great Britain, France, Belgium and the Netherlands. For each of the 6,661 species, subspecies and hybrids listed, we provide detailed information on its status in each country, taxonomic affiliation and environment inhabited. The data were collected by review of 36 web- and print-based sources over an eight-month period. Further systematic scanning of three of the most relevant scientific journals, i.e. Neobiota, Aquatic Invasions and BioInvasions Records, recovered 19 additional relevant publications from which information was included in the registry. As a result, the registry will serve as a basis for developing effective, cross-boundary strategies to manage and control non-native species, which can have severe ecological and economic impacts. The registry can further be used as a general reference for both scientists and practitioners, as well as a tool to assess reliability and comprehensiveness of other well-known databases such as the DAISIE portal.
The article reviews distribution records of Deroceras invadens (previously called D. panormitanum and D. caruanae), adding significant unpublished records from the authors’ own collecting, museum samples, and interceptions on goods arriving in the U.S.A. By 1940 D. invadens had already arrived in Britain, Denmark, California, Australia and probably New Zealand; it has turned up in many further places since, including remote oceanic islands, but scarcely around the eastern Mediterranean (Egypt and Crete are the exceptions), nor in Asia. Throughout much of the Americas its presence seems to have been previously overlooked, probably often being mistaken for D. laeve. New national records include Mexico, Costa Rica, and Ecuador, with evidence from interceptions of its presence in Panama, Peru, and Kenya. The range appears limited by cold winters and dry summers; this would explain why its intrusion into eastern Europe and southern Spain has been rather slow and incomplete. At a finer geographic scale, the occurrence of the congener D. reticulatum provides a convenient comparison to control for sampling effort; D. invadens is often about half as frequently encountered and sometimes predominates. Deroceras invadens is most commonly found in synanthropic habitats, particularly gardens and under rubbish, but also in greenhouses, and sometimes arable land and pasture. It may spread into natural habitats, as in Britain, South Africa,
Australia and Tenerife. Many identifications have been checked in the light of recent taxonomic revision, revealing that the sibling species D. panormitanum s.s. has spread much less extensively. A number of published or online records, especially in Australia, have turned out to be misidentifications of D. laeve.
Non-neuronal acetylcholine plays a substantial role in the human skin by influencing adhesion, migration, proliferation and differentiation of keratinocytes. These processes are regulated by the Mitogen-Activated Protein (MAP) kinase cascade. Here we show that in HaCaT keratinocytes all five muscarinic receptor subtypes are expressed, but M1 and M3 are the subtypes involved in mitogenic signaling. Stimulation with the cholinergic agonist carbachol leads to activation of the MAP kinase extracellular signal regulated kinase, together with the protein kinase Akt. The activation is fully dependent on the transactivation of the epidermal growth factor receptor (EGFR), which even appears to be the sole pathway for the muscarinic receptors to facilitate MAP kinase activation in HaCaT cells. The transactivation pathway involves a triple-membrane-passing process, based on activation of matrix metalloproteases, and extracellular ligand release; whereas phosphatidylinositol 3-kinase, Src family kinases or protein kinase C do not appear to be involved in MAP kinase activation. Furthermore, phosphorylation, ubiquitination and endocytosis of the EGF receptor after cholinergic transactivation are different from that induced by a direct stimulation with EGF, suggesting that ligands other than EGF itself mediate the cholinergic transactivation.
Im Aufsatz versucht der Autor, nach einer textgestützten Interpretation von Martial II 51, zu zeigen, wie der Epigrammatiker die Fabel des augusteischen Historikers Livius vom Magen und den Gliedern (II 32,9ff.) in eine frivole Parodie überführt und sie zu einer witzigen und grotesken Karikatur verformt – ein spöttisches Spiel mit gattungs- und literaturgeschichtlichen Elementen.
Die bisher vorliegenden Lesungen einer fragmentarischen Weihinschrift aus Solothurn/Salodurum (CIL XIII 5170) müssen in einigen Punkten korrigiert werden. So ist die Lesung des Personennamens [O]pilius, Ma[o]pilius, Ma[ga]pilius oder Mapilius zu verwerfen. Wahrscheinlich führte der Dedikant der Inschrift den Namen M(arcus) A(urelius) [Ap]rilius. Das Gentilnomen Aprilius ist in den germanischen Provinzen und der Gallia Belgica mehrfach bezeugt.
In den römischen Grabinschriften 2. N. Nr.129 (Mittelstrimmig) und CIL XIII 6202 (Schwarzerden) sollte D•F zu d(e)f(unctis) bzw. d(e)f(uncto) aufgelöst werden und nicht zu D(ecimi) f(ilio) bzw. d(efuncto) f(ecit). Die Wendung defunctus kommt im gallisch-germanischen Raum vor allem in Bordeaux/Burdigala und im Gebiet von Trier/Augusta Treverorum vor.
It has become increasingly apparent over the last decades that cooking pottery played a considerable role as a trade commodity in ancient times, yet relatively little research has yet been done on this topic for its own sake. By taking a closer look at the cooking pottery found in Priene, a small city in southern Ionia re-founded in the middle of the 4th century BCE, we want to trace some of the broader developments within the cooking wares that were used over a period of roughly 300 years. The aim is not only to outline the general shapes that were in use over this period of time, but also to register if and how these shapes correlate with the different fabrics observed in Priene so far.
The title compound, [Li2(C25H23BN4OP)2], features a centrosymmetric dimeric complex. The four-memberered Li2O2 ring is exactly planar due to symmetry. The Li atom is four-coordinated by two O atoms and by two N atoms of two different pyrazole rings. The dihedral angle between two pyrazole rings bonded to the same B atom is 45.66 (9)°. The B—N—N—Li—N—N metalla ring adopts a boat conformation. The crystal packing is stabilized by van der Waals interactions only.
The structure of the title compound, C8H16N4, which consists of four fused seven-membered rings, has been redetermined at 173 K. This redetermination corrects the orientation of two H atoms, which were located at unrealistic positions in the original room-temperature study [Murray-Rust (1974[Murray-Rust, P. (1974). J. Chem. Soc. Perkin Trans. 2, pp. 1136-1141.]). J. Chem. Soc. Perkin Trans. 2, pp. 1136–1141]. The complete molecule is generated by -42m symmetry, with one quarter of a molecule [one N atom (site symmetry m), two C atoms (one with site symmetry m and the other with site symmetry 2) and two H atoms] in the asymmetric unit. No directional interactions beyond van der Waals contacts are apparent in the crystal structure.
In the title compound, C40H76Si, the Si atom is located on a special position of site symmetry -4. Thus, there is just a quarter of a molecule in the asymmetric unit. The C=C double bonds exhibit a trans configuration. The Si atom and the tert-butyl group are located on the same side of the plane formed by the C=C double bond and its four substituents. The crystal packing shows no short contacts between the molecules and despite the low crystal density (0.980 Mg m−3), there are no significant voids in the structure.
In the title compound, C19H24N2O2, a di-Mannich base derived from 2-methylphenol and 1,3,6,8-tetraazatricyclo[4.4.1.13,8]dodecane, the imidazolidine ring adopts a twist conformation, with a twist about the ring N—C bond [C—N—C—C torsion angle = −44.34 (14)°]. The two 2-hydroxy-3-methylbenzyl groups are located in trans positions with respect to the imidazolidine fragment. The structure displays two intramolecular O—H⋯N hydrogen bonds, which each form an S(6) ring motif. In the crystal, the molecules are linked by weak C—H⋯O interactions with a bifurcated acceptor, forming a three-dimensional network.
In the title solvate, C14H12N2O·0.5C6H6, the complete benzene molecule is generated by a crystallographic inversion centre. The dihedral angle between the planes of the benzimidazole moiety and the phenol substituent is 75.28 (3)°. In the crystal, O—H⋯N hydrogen bonds link the molecules into parallel chains propagating along [100]. The molecules are further connected by C—H⋯π interactions.
Background: The invasive eel parasite Anguillicoloides crassus (syn. Anguillicola crassus) is considered one of the major causes for the decline of the European eel (Anguilla anguilla) panmictic population. It impairs the swim bladder function and reduces swimming performance of its host. The life cycle of this parasite involves different intermediate and paratenic hosts. Despite an efficient immune system of the paratenic fish hosts acting against infections with A. crassus, levels of parasitized eels remain high in European river systems. Recently, the round goby Neogobius melanostomus (Gobiidae) has become dominant in many rivers in Europe and is still spreading at a rapid pace. This highly invasive species might potentially act as an important, so far neglected paratenic fish host for A. crassus.
Methods: Based on own observations and earlier single sightings of A. crassus in N. melanostomus, 60 fresh individuals of N. melanostomus were caught in the Rhine River and examined to assess the infection levels with metazoan parasites, especially A. crassus. Glycerin preparations were used for parasite identification.
Results: The parasite most frequently found in N. melanostomus was the acanthocephalan Pomphorhynchus sp. (subadult stage) which occurred mainly encysted in the mesenteries and liver. Every third gobiid (P = 31.7%) was infected by A. crassus larvae (L3) which exclusively occurred inside the acanthocephalan cysts. No intact or degenerated larvae of A. crassus were detected elsewhere in the goby, neither in the body cavity and mesenteries nor in other organs. Affected cysts contained the acanthocephalan larvae and 1-12 (mI =3) living A. crassus larvae. Additionally, encysted larvae of the nematode Raphidascaris acus were detected in the gobies, but only in the body cavity and not inside the acanthocephalan cysts.
Conclusions: Based on our observations, we suggest that A. crassus might actively bypass the immune response of N. melanostomus by invading the cysts of acanthocephalan parasites of the genus Pomphorhynchus using them as "Trojan horses". Providing that eels prey on the highly abundant round goby and that the latter transfers viable infective larvae of A. crassus, the new paratenic host might have a strong impact on the epidemiology of A. crassus.
The late physicist Carl Sagan, whom I quote in the first part of my title, skillfully phrased the common sense view on evidence in the mature sciences. In linguistics, however, evidence has become a controversial issue, especially so when it comes to the investigation of less well studied languages. In this paper, I argue that Sagan's principle should be applied to linguistics. The growing accessibility of a wide array of experimental techniques and computational tools to analyze such data makes it feasible to back up extraordinary claims with evidence from a variety of sources. At the same time, it is in many cases possible to agree on what constitutes an ordinary claim and focus the extra effort on extraordinary claims. For non-controversial claims no more than the minimum effort to establish the claim and properly document the evidence is necessary.
Im Folgenden soll kurz geklärt werden, was Genus ist (Kap. 2) und – auch wenn diese Frage nicht mit unserem derzeitigen Wissen beantwortbar ist – woher Genus kommen könnte (Kap. 3). Hauptsächlich stellt sich jedoch die Frage: Was tun mit Genus, das heute das Endstadium einer langen Grammatikalisierung darstellt (Kap. 4)? Hier wird die wichtigste Antwort lauten: Genus hat eine neue, eine syntaktische Nutzung erfahren, indem es maßgeblich daran beteiligt ist, unsere berühmten Nominalklammern zu bauen (4.1). Außerdem gibt es weitere "Recyclingmöglichkeiten" von Genus, nämlich: a) Objekte, die Namen tragen, zu klassifizieren (die Kaiser Wilhelm), b) Beziehungen zwischen namentragenden und namenverwendenden Personen zu qualifizieren (der Peterle, das Anna) oder sogar c) Personen zu degradieren (das Merkel). Mit Punkt a) begebe ich mich in die Onomastik, mit Punkt b) in die Dialektologie, und mit Punkt c) werde ich mit der Genderlinguistik enden.
Mapping is an important tool for the management of plant invasions. If landscapes are mapped in an appropriate way, results can help managers decide when and where to prioritize their efforts. We mapped vegetation with the aim of providing key information for managers on the extent, density and rates of spread of multiple invasive species across the landscape. Our case study focused on an area of Galapagos National Park that is faced with the challenge of managing multiple plant invasions. We used satellite imagery to produce a spatially explicit database of plant species densities in the canopy, finding that 92% of the humid highlands had some degree of invasion and 41% of the canopy was comprised of invasive plants. We also calculated the rate of spread of eight invasive species using known introduction dates, finding that species with the most limited dispersal ability had the slowest spread rates while those able to disperse long distances had a range of spread rates. Our results on spread rate fall at the lower end of the range of published spread rates of invasive plants. This is probably because most studies are based on the entire geographic extent, whereas our estimates took plant density into account. A spatial database of plant species densities, such as the one developed in our case study, can be used by managers to decide where to apply management actions and thereby help curtail the spread of current plant invasions. For example, it can be used to identify sites containing several invasive plant species, to find the density of a particular species across the landscape or to locate where native species make up the majority of the canopy. Similar databases could be developed elsewhere to help inform the management of multiple plant invasions over the landscape.
