A grammar of Pite Saami
(2014)
Pite Saami is a highly endangered Western Saami language in the Uralic language family currently spoken by a few individuals in Swedish Lapland. This grammar is the first extensive book-length treatment of a Saami language written in English. While focussing on the morphophonology of the main word classes nouns, adjectives and verbs, it also deals with other linguistic structures such as prosody, phonology, phrase types and clauses. Furthermore, it provides an introduction to the language and its speakers, and an outline of a preliminary Pite Saami orthography. An extensive annotated spoken-language corpus collected over the course of five years forms the empirical foundation for this description, and each example includes a specific reference to the corpus in order to facilitate verification of claims made on the data. Descriptions are presented for a general linguistics audience and without attempting to support a specific theoretical approach, but this book should be equally useful for scholars of Uralic linguistics, typologists, and even learners of Pite Saami.
We consider a class of nonautonomous nonlinear competitive parabolic systems on bounded radial domains under Neumann or Dirichlet boundary conditions. We show that, if the initial profiles satisfy a reflection inequality with respect to a hyperplane, then bounded positive solutions are asymptotically (in time) foliated Schwarz symmetric with respect to antipodal points. Additionally, a related result for (positive and sign changing solutions) of scalar equations with Neumann or Dirichlet boundary conditions is given. The asymptotic shape of solutions to cooperative systems is also discussed.
What happened in Cyprus? The economic consequences of the last communist government in Europe
(2014)
This paper reviews developments in the Cypriot economy following the introduction of the euro on 1 January 2008 and leading to the economic collapse of the island five years later. The main cause of the collapse is identified with the election of a communist government in February 2008, within two months of the introduction of the euro, and its subsequent choices for action and inaction on economic policy matters. The government allowed a rapid deterioration of public finances, and despite repeated warnings, damaged the country's creditworthiness and lost market access in May 2011. The destruction of the island's largest power station in July 2011 subsequently threw the economy into recession. Together with the intensification of the euro area crisis in the summer and fall of 2011, these events weakened the banking system which was vulnerable due to its exposure in Greece. Rather than deal with its fiscal crisis, the government secured a loan from the Russian government that allowed it to postpone action until after the February 2013 election. Rather than protect the banking system, losses were imposed on banks and a campaign against them was coordinated and used as a platform by the communist party for the February 2013 election. The strategy succeeded in delaying resolution of the crisis and avoiding short-term political cost for the communist party before the election, but also in precipitating a catastrophe right after the election.
So-called medicanes (Mediterranean hurricanes) are meso-scale, marine, and warm-core Mediterranean cyclones that exhibit some similarities to tropical cyclones. The strong cyclonic winds associated with medicanes threaten the highly populated coastal areas around the Mediterranean basin. To reduce the risk of casualties and overall negative impacts, it is important to improve the understanding of medicanes with the use of numerical models. In this study, we employ an atmospheric limited-area model (COSMO-CLM) coupled with a one-dimensional ocean model (1-D NEMO-MED12) to simulate medicanes. The aim of this study is to assess the robustness of the coupled model in simulating these extreme events. For this purpose, 11 historical medicane events are simulated using the atmosphere-only model, COSMO-CLM, and coupled model, with different setups (horizontal atmospheric grid-spacings of 0.44°, 0.22°, and 0.08°; with/without spectral nudging, and an ocean grid-spacing of 1/12°). The results show that at high-resolution, the coupled model is able to not only simulate most of medicane events but also improve the track length, core temperature, and wind speed of simulated medicanes compared to the atmosphere-only simulations. The results suggest that the coupled model is more proficient for systemic and detailed studies of historical medicane events, and that this model can be an effective tool for future projections.
Background: The aim of this study was to compare outcome of patients with previous cardiac surgery undergoing transapical aortic valve implantation (Redo-TAVI) to those undergoing classic aortic valve replacement (Redo-AVR) by using propensity analysis.
Methods: From January 2005 through May 2012, 52 high-risk patients underwent Redo-TAVI using a pericardial xenograft fixed within a stainless steel, balloon-expandable stent (Edwards SAPIEN™). During the same period of time 167 patients underwent classic Redo-AVR. Logistic regression analysis was used to identify covariates among 11 baseline patient variables including the type of initial surgery. Using the significant regression coefficients, each patient’s propensity score was calculated, allowing selectively matched subgroups of 40 patients each. Initial surgery included coronary artery bypass grafting in 30 patients, aortic valve replacement in 7 patients and mitral valve reconstruction in 3 patients in each group. Follow-up was 4 ± 2 years and was 100% complete.
Results: Postoperative chest tube drainage (163 ± 214 vs. 562 ± 332 ml/24 h, p = 0.02) and incidence of early permanent neurologic deficit (0 vs. 13%, p = 0.04) was lower in patients with Redo-TAVI and there was a trend towards improved 30-day survival (p = 0.06). Also we detected a decreased ventilation time (p = 0.04) and lower transfusion rate of allogenic blood products (p ≤ 0.05) in the Redo-TAVI group. At late follow up differences regarding incidence of major adverse events, including death and permanent neurologic deficits (25% vs. 43%, p = 0.01) statistically supported early postoperative findings.
Conclusion: The encouraging results regarding early and long-term outcomes following TAVI in patients with previous cardiac surgery show, that this evolving approach may be particularly beneficial in this patient cohort.
The role of RNA interference in the developmental separation of blood and lymphatic vasculature
(2014)
Background: Dicer is an RNase III enzyme that cleaves double stranded RNA and generates functional interfering RNAs that act as important regulators of gene and protein expression. Dicer plays an essential role during mouse development because the deletion of the dicer gene leads to embryonic death. In addition, dicer-dependent interfering RNAs regulate postnatal angiogenesis. However, the role of dicer is not yet fully elucidated during vascular development.
Methods: In order to explore the functional roles of the RNA interference in vascular biology, we developed a new constitutive Cre/loxP-mediated inactivation of dicer in tie2 expressing cells.
Results: We show that cell-specific inactivation of dicer in Tie2 expressing cells does not perturb early blood vessel development and patterning. Tie2-Cre; dicerfl/fl mutant embryos do not show any blood vascular defects until embryonic day (E)12.5, a time at which hemorrhages and edema appear. Then, midgestational lethality occurs at E14.5 in mutant embryos. The developing lymphatic vessels of dicer-mutant embryos are filled with circulating red blood cells, revealing an impaired separation of blood and lymphatic vasculature.
Conclusion: Thus, these results show that RNA interference perturbs neither vasculogenesis and developmental angiogenesis, nor lymphatic specification from venous endothelial cells but actually provides evidence for an epigenetic control of separation of blood and lymphatic vasculature.
The recent approval by the US Food and Drug Administration of ocriplasmin for the treatment of symptomatic vitreomacular adhesion (VMA), often associated with vitreomacular traction (VMT) and macular hole (MH), has brought new attention to the field of pharmacologic vitreolysis. The need for an enzyme to split the vitreomacular interface, which is formed by a strong adhesive interaction between the posterior vitreous cortex and the internal limiting membrane, historically stems from pediatric eye surgery. This review summarizes the different anatomic classifications of posterior vitreous detachment or anomalous posterior vitreous detachment and puts these in the context of clinical pathologies commonly observed in clinical practice of the vitreoretinal specialist, such as MH, VMT, age-related macular degeneration, and diabetic macular edema. We revisit the outcome of the Phase II studies that indicated ocriplasmin was a safe and effective treatment for selected cases of symptomatic VMA and MH. Release of VMA at day 28 was achieved by 26.5% of patients in the ocriplasmin group versus 10.1% in the placebo group (P<0.001). Interestingly, for MHs, the numbers were more remarkable. Predictive factors for successful ocriplasmin treatment were identified for VMT (VMA diameter smaller than 1,500 µm) and MH (smaller than 250 µm). In comparison with the highly predictable outcome after vitrectomy, the general success rate of ocriplasmin not under clinical trial conditions has not fully met expectations and needs to be proven in real-world clinical settings. The ocriplasmin data will be compared in the future with observational data on spontaneous VMA release, will help retina specialists make more accurate predictions, and will improve outcome rates.
Die Struktur der makroprudenziellen Politik in der Europäischen Union ist ausgesprochen komplex und für den außenstehenden Betrachter fast undurchdringlich geworden. Deshalb wurde mit den Titeln der drei Kapitel des vorliegenden Aufsatzes „Der Prozess“, „Das Schloss“ und „Das Urteil“ bewusst auf Werke von Franz Kafka angespielt. Während sich der erste Teil der Arbeit vor allem mit der Komplexität des funktionellen Transmissionsprozesses in der makroprudenziellen Politik beschäftigt, widmet sich das zweite Kapitel, also der „Schloss-Teil“, ihren institutionellen Verflechtungen. Und am Ende werden die Ausführungen in einem „Wert-Urteil“ zusammengefasst.
On January 29, 2014, EU Commissioner Barnier published a draft law proposing a ban for proprietary trading by big banks in Europe. In this opinion piece, published in a German newspaper on 30 January, 2014, Jan Pieter Krahnen, who was a member of the Liikanen Commission, argues that the proposal could prove to be effective in preventing systemic risk.
Ein Freibrief für die Notenbank bedeutet, genau genommen, die Bankrotterklärung des demokratischen Verfassungsstaates vor technokratischen Beliebigkeiten, schreibt Helmut Siekmann in diesem Namensbeitrag. Er betont, dass die Europäische Union eine unverzichtbare Einrichtung ist und ein echter Bundesstaat sein sollte. Sie sei aber im Wesentlichen (nur) ein Rechtskonstrukt, weshalb es umso wichtiger sei, dass die rechtlichen Regeln, auf denen sie beruht, genauestens beachtet werden.
The investigated haloarchaeal species, Halobacterium salinarum, Haloferax mediterranei, and H. volcanii, have all been shown to be polyploid. They contain several replicons that have independent copy number regulation, and most have a higher copy number during exponential growth phase than in stationary phase. The possible evolutionary advantages of polyploidy for haloarchaea, most of which have experimental support for at least one species, are discussed. These advantages include a low mutation rate and high resistance toward X-ray irradiation and desiccation, which depend on homologous recombination. For H. volcanii, it has been shown that gene conversion operates in the absence of selection, which leads to the equalization of genome copies. On the other hand, selective forces might lead to heterozygous cells, which have been verified in the laboratory. Additional advantages of polyploidy are survival over geological times in halite deposits as well as at extreme conditions on earth and at simulated Mars conditions. Recently, it was found that H. volcanii uses genomic DNA as genetic material and as a storage polymer for phosphate. In the absence of phosphate, H. volcanii dramatically decreases its genome copy number, thereby enabling cell multiplication, but diminishing the genetic advantages of polyploidy. Stable storage of phosphate is proposed as an alternative driving force for the emergence of DNA in early evolution. Several additional potential advantages of polyploidy are discussed that have not been addressed experimentally for haloarchaea. An outlook summarizes selected current trends and possible future developments.
A multiple filter test for the detection of rate changes in renewal processes with varying variance
(2014)
The thesis provides novel procedures in the statistical field of change point detection in time series.
Motivated by a variety of neuronal spike train patterns, a broad stochastic point process model is introduced. This model features points in time (change points), where the associated event rate changes. For purposes of change point detection, filtered derivative processes (MOSUM) are studied. Functional limit theorems for the filtered derivative processes are derived. These results are used to support novel procedures for change point detection; in particular, multiple filters (bandwidths) are applied simultaneously in oder to detect change points in different time scales.

Panel Sample Selection ModelsThe empirical evidence currently available in the literature regarding the effects of a country's IMF program participation on its output growth is rather inconclusive. In this paper we propose and estimate a panel data sample selection model featuring state dependence. As in this model the output growth effects of program participation can be conditional on the realization of a state variable (conditional pooling), our framework may reconcile previous empirical evidence based on models without state-dependent effects. We find that the effects of IMF program participation on output growth vary systematically with an index reflecting a country's institutional record, and that output growth effects of program participation are significantly positive only if the program participation is coupled with sufficient improvement of the institutional record.
Das Forschungsunternehmen "Romanisch und Deutsch am Hinterrhein / GR" von Prof. Dr. Theodor Ebneter (Sprachlabor der Universität Zürich) wurde in den Jahren 1978-1992 am Phonogrammarchiv der Universität Zürich als erstes bilinguistisches Projekt durchgeführt.
Für jede der vier Talschaften des Hinterrheins waren ursprünglich zwei Bände, einer für das Deutsche und einer für das Romanische, vorgesehen. […] Da die Gewährsleute ihre jeweilige Mundart gerne mit jener von Chur vergleichen, wurde die Dissertation von Oscar Eckhardt "Die Mundart der Stadt Chur" (1991)als Band 9 veröffentlicht.
Nachdem Prof. Ebneters Leitung des Phonogrammarchivs 1992 zu Ende ging, konnte mit Unterstützung des Schweizerischen Nationalfonds Band 7 "Romanisch im Boden, in Trin und in Flims" mit seinem Umfang von 622 Seiten abgeschlossen werden, der als romanistische Ergänzung zu Urs Willis 1990 publiziertem Band 8 "Deutsch im Bezirk Imboden " die Untersuchung dieser vierten und letzten Talschaft beschliessen sollte.
Der vorliegende Band 11 der Reihe "Romanisch und Deutsch am Hinterrhein / GR" ersetzt nun Willis Band 8 und schliesst zugleich das Forschungsuntemehmen mit der germanistischen Aufarbeitung des Bodens, von Trins und von Flims ab. Dieser Band wurde von Dr. Alfred Toth und Prof. Dr. Theodor Ebneter parallel zur Herstellung von Band 10 "Die romanisch-deutsche Sprachlandschaft am unteren Hinterrhein" verfasst. Die Ersetzung von Willis Band durch den vorliegenden war auch deshalb nötig, um die die deutschen Mundarten des Bezirks Imboden betreffenden Daten in Band 10 einbauen zu können. Zu diesem Zweck wurden im Winter und Frühling 1994/95 alle Ortschaften des Bezirks Imboden mit 27 Gewährspersonen in längeren Gesprächen aufgenommen.
Band 11 orientiert sich methodisch einerseits an Band 7 über die romanistische Situation des Bezirks Imboden, dessen germanistische Ergänzung er darstellt, anderseits an Band 9 über die Mundart von Chur, der innerhalb der Reihe zum erstenmal vergleichsweise herangezogen werden konnte, nachdem alle übrigen germanistischen Bände früher erschienen waren. Aus diesem Grunde wurde der Einleitung (Kap. 1), der Phonologie (Kap. 2) und der Morphologie (Kap. 3) ein Kapitel 4 "Vergleich der Dialekte des Bezirks Imboden mit der Mundart der Stadt Chur" beigesteIlt, in dem auch Aspekte der Morphosyntax (Kap. 4.3.), der Syntax (Kap. 4.4.) sowie der Lexikologie (Kap. 4.5.) behandelt werden.
Nachdem ich meine Lizentiatsarbeit [..] abgeschlossen hatte, fragte mich Prof. Ebneter an, ob ich bereit wäre, mit dem gleichen Transkritionssystem auch eine Umfrage zu diversen Verbalformen in Graubünden zu erstellen. […] Von Prof. Ebneter bekam ich eine Liste mit den gewünschten Verbformen. Ich habe zu diesen je einen Satz konstruiert, der den Gewährspersonen vorgelegt wurde. Einmal hatten die Informantinnen und Informanten die Verbformen mit vorangestelltem Subjektpronomen und einmal mit Inversion aus der standardsprachliche Vorlage in der 1. Person Singular zu übersetzen. In der Folge habe ich dann das ganze Paradigma abgefragt.
Die Resultate meiner Erhebung sind teilweise in die Verbalmorphologie des Abschlussbandes zum Forschungsprojekt "Deutsch und Romanisch am Hinterrhein" eingeflossen. Insgesamt aber sind die Verbformen noch nie integral veröffentlicht worden. Eine eigenständige gedruckte Publikation verlangte wohl auch einen Kommentar zu den Paradigmen. Mit der Möglichkeit, Texte auch digital zu publizieren, hat sich allerdings eine neue Verbreitungsform ergeben, die es erlaubt, auch "Materialien" zu veröffentlichen, die vielleicht anderen wissenschaftlich Arbeitenden nützlich sein können. Im Zeichen des zum Teil rapiden Sprachwandels gerade in der Verbalmorphologie stellen die 1988 erfassten Verbparadigmen aber auch ein Brückendokument dar, das spannende Vergleiche zwischen den Aussagen früherer Forschungen und aktuellen Daten zulässt.
Although oil price shocks have long been viewed as one of the leading candidates for explaining U.S. recessions, surprisingly little is known about the extent to which oil price shocks explain recessions. We provide the first formal analysis of this question with special attention to the possible role of net oil price increases in amplifying the transmission of oil price shocks. We quantify the conditional recessionary effect of oil price shocks in the net oil price increase model for all episodes of net oil price increases since the mid-1970s. Compared to the linear model, the cumulative effect of oil price shocks over course of the next two years is much larger in the net oil price increase model. For example, oil price shocks explain a 3% cumulative reduction in U.S. real GDP in the late 1970s and early 1980s and a 5% cumulative reduction during the financial crisis. An obvious concern is that some of these estimates are an artifact of net oil price increases being correlated with other variables that explain recessions. We show that the explanatory power of oil price shocks largely persists even after augmenting the nonlinear model with a measure of credit supply conditions, of the monetary policy stance and of consumer confidence. There is evidence, however, that the conditional fit of the net oil price increase model is worse on average than the fit of the corresponding linear model, suggesting much smaller cumulative effects of oil price shocks for these episodes of at most 1%.
Efforts to control bank risk address the wrong problem in the wrong way. They presume that the financial crisis was caused by CEOs who failed to supervise risk-taking employees. The responses focus on executive pay, believing that executives will bring non-executives into line—using incentives to manage risk-taking—once their own pay is regulated. What they overlook is the effect on non-executive pay of the competition for talent. Even if executive pay is regulated, and executives act in the bank’s best interests, they will still be trapped into providing incentives that encourage risk-taking by non-executives due to the negative externality that arises from that competition. Greater risk-taking can increase short-term profits and, in turn, the amount a non-executive receives, potentially at the expense of long-term bank value. Non-executives, therefore, have an incentive to incur significant risk upfront so long as they can depart for a new employer before any losses materialize. The result is an upward spiral in compensation—reducing an executive’s ability to set non-executive pay and the ability of any one bank to adjust compensation to reflect risk-taking and long-term outcomes. New regulation must address the tension between compensation and competition. Regulators should take account of the effect of competition on market-wide levels of pay, including by non-banks who compete for talent. The ability of non-executives to jump from a bank employer to another financial firm should also be limited. In addition, banks should be required to include a long-term equity component in non-executive pay, with subsequent employers being restricted from compensating a new employee for any losses she incurs related to her prior work.
We examine trust and trustworthiness of individuals with varying professional preferences and experiences. Our subjects study business and economics in Frankfurt, the financial center of Germany and continental Europe. In the trust game, subjects with a high interest in working in the financial industry return 25 percent less than subjects with a low interest. We find no evidence that the extent of professional experience in the financial industry has a negative impact on trustworthiness. We also do not find any evidence that the financial industry screens out less trustworthy individuals in the hiring process. In a prediction game that is strategically equivalent to the trust game, the amount sent by first-movers was significantly smaller when the second-mover indicated a high interest in working in finance. These results suggest that the financial industry attracts less trustworthy individuals, which may contribute to the current lack of trust in its employees.
In the wake of the Global Financial Crisis that started in 2007, policymakers were forced to respond quickly and forcefully to a recession caused not by short-term factors, but rather by an over-accumulation of debt by sovereigns, banks, and households: a so-called “balance sheet recession.” Though the nature of the crisis was understood relatively early on, policy prescriptions for how to deal with its consequences have continued to diverge. This paper gives a short overview of the prescriptions, the remaining challenges and key lessons for monetary policy.
n a contribution prepared for the Athens Symposium on “Banking Union, Monetary Policy and Economic Growth”, Otmar Issing describes forward guidance by central banks as the culmination of the idea of guiding expectations by pure communication. In practice, he argues, forward guidance has proved a misguided idea. What is presented as state of the art monetary policy is an example of pretence of knowledge. Forward guidance tries to give the impression of a kind of rule-based monetary policy. De facto, however, it is an overambitious discretionary approach which, to be successful, would need much more (or rather better) information than is currently available. In Issing's view, communication must be clear and honest about the limits of monetary policy in a world of uncertainty.
Die „Rente mit 63“ hat wieder einmal den Blick auf den Renteneintritt gerichtet. In der öffentlichen Debatte werden dabei zwei Ereignisse regelmäßig vermischt: das Ende des Arbeitslebens und der Beginn der Rentenzahlung. Dabei müssen beide nicht unmittelbar aufeinander folgen. Unter bestimmten Umständen kann es finanziell attraktiv sein, die staatliche Rente nicht sofort nach dem Ausstieg aus dem Erwerbsleben zu beantragen, sondern die Ausgaben bis zum späteren Rentenbeginn durch den Abbau von Finanzkapital zu finanzieren. Dieser Beitrag gibt einen kurzen Einblick in die neueste Studie von Olivia Mitchell, Andreas Hubener und Raimund Maurer zur Alterssicherung in den USA und stellt auch Berechnungen für Deutschland auf.
Jubiläen drängen zur Standortbestimmung. Im Jahr 2014 feiert die Frankfurter Goethe Universität ihren 100. Geburtstag. Man lud zu Bilanzen ein, zum Blick nach vorn, auf Erfahrungen und Erwartungen der Rechtswissenschaft und ihrer Teildisziplinen. In diese Spannung stellt sich auch dieser Beitrag zu den Perspektiven des Fachs ‚Rechtsgeschichte‘. Es wird deswegen nur kurz um 100 Jahre (I.), wenig um die Zeit nach 1945 (II.), weit mehr um Rahmenbedingungen rechtshistorischen Forschens in der ‚Berliner Republik‘ (III.) – und um Zukunftsperspektiven des Fachs gehen (IV.).
Results of an Odonata survey carried out in the peatlands of Central Kalimantan, Indonesia, in 2012
(2014)
The results of a survey of Odonata (dragonflies and damselflies) in the peat lands of Central Kalimantan, Indonesia, in 2012 are presented. Fifty four species of Odonata found in the area in June-July 2012 are listed, along with brief notes and the locations in which they were found. Of the species found, twelve had not been recorded in Central Kalimantan previously, and of these at least four are completely new to science. Six species, originally described from Central Kalimantan and not recorded any- where since 1953, were rediscovered. At least sixteen of the species found during the survey are considered to be of conservation concern. The discovery of at least four new species to science in a relatively short survey indicates a high probability of occurrence of many more species that are awaiting discovery, and that many un-discovered species may be lost or highly threatened because of the rapid demise of peat swamp forest habitats. A checklist of the Odonata known from Central Kalimantan is provided in an appendix.
The human endothelin receptors, ETA and ETB, are two members of the G-protein coupled receptors family (GPCRs) and they are key players in cardiovascular regulation. The characterization of their functionality in vitro has been limited by the possibility to obtain high quality samples using conventional expression systems. The Cell-Free expression system is an alternative technique for the production of membrane protein as well as GPCRs and can overcome some of the limitations that are commonly encountered using an in vivo approach. Cell-Free expression protocols for the two receptors ETA and ETB have been optimized by implementing post- and co-translational association to lipid bilayers. The efficiency of the reconstitution or association to liposomes and nanodiscs has systematically been studied and the ligand binding properties of the two receptors have been analyzed using a set of different complementary techniques. In several different conditions a high affinity binding of the peptide ligand ET-1 to both endothelin receptors could be obtained and the highest activity values were detected in sample prepared using a co-translational approach in presence of nanodiscs. Furthermore, the characteristic differential binding pattern of selected agonists and antagonists to the two receptors was confirmed. In samples obtained from several Cell-Free expression conditions, two intrinsic properties of the functionally folded ETB receptor, such as the proteolytic processing based on conformational recognition as well as the formation of SDS-resistant complexes with the peptide ligand ET-1, were detected. ETA and ETB are able to induce in vivo the activation of hetrotrimeric G proteins upon stimulation with an agonist, leading to the dissociation of the heterotrimeric complex and the exchange of GDP to GTP in the Galpha subunit. The Cell-Free expression system was chosen for the production of two G alpha subunit, Galpha s and Galpha q. Soluble expression of the two proteins was achieved and the production of active Galpha s was confirmed using fluorescent as well as radioactive assays. In conclusion, the obtained results document a new process for the production of ligand binding competent endothelin receptors, as well as Galpha proteins, using a Cell-Free expression system. The combination of this expression system and the nanodiscs technology appears to be a promising tool for the further characterization of membrane proteins as well as GPCRs.
We investigate the relationship between anchoring and the emergence of bubbles in experimental asset markets. We show that setting a visual anchor at the fundamental value (FV) in the first period only is sufficient to eliminate or to significantly reduce bubbles in laboratory asset markets. If no FV-anchor is set, bubble-crash patterns emerge. Our results indicate that bubbles in laboratory environments are primarily sparked in the first period. If prices are initiated around the FV, they stay close to the FV over the entire trading horizon. Our insights can be related to initial public offerings and the interaction between prices set on pre-opening markets and subsequent intra-day price dynamics.
he observed hump-shaped life-cycle pattern in individuals' consumption cannot be explained by the classical consumption-savings model. We explicitly solve a model with utility of both consumption and leisure and with educational decisions affecting future wages. We show optimal consumption is hump shaped and determine the peak age. The hump results from consumption and leisure being substitutes and from the implicit price of leisure being decreasing over time; more leisure means less education, which lowers future wages, and the present value of foregone wages decreases with age. Consumption is hump shaped whether the wage is hump shaped or increasing over life.
This paper provides a systematic analysis of individual attitudes towards ambiguity, based on laboratory experiments. The design of the analysis allows to capture individual behavior across various levels of ambiguity, ranging from low to high. Attitudes towards risk and attitudes towards ambiguity are disentangled, providing pure measures of ambiguity aversion. Ambiguity aversion is captured in several ways, i.e. as a discount factor net of a risk premium, and as an estimated parameter in a generalized utility function. We find that ambiguity aversion varies across individuals, and with the level of ambiguity, being most prominent for intermediate levels. Around one third of subjects show no aversion, one third show maximum aversion, and one third show intermediate levels of ambiguity aversion, while there is almost no ambiguity seeking. While most theoretical work on ambiguity builds on maxmin expected utility, our results provide evidence that MEU does not adequately capture individual attitudes towards ambiguity for the majority of individuals. Instead, our results support models that allow for intermediate levels of ambiguity aversion. Moreover, we find risk aversion to be statistically unrelated to ambiguity aversion on average. Taken together, the results support the view that ambiguity is an important and distinct argument in decision making under uncertainty.
Paul Tillich wurde 1929 nach Frankfurt/M., wo es damals noch keine Theologische Fakultät gab, auf den Lehrstuhl für Philosophie mit der Verpflichtung berufen, „Philosophie und die Soziologie einschließlich Sozialpädagogik“ zu vertreten. Der ordinierte Pfarrer verstand die Konzentration auf die Philosophie gerade nicht als Absage an die Theologie; er sah sich immer als ein Grenzgänger, ohne Überläufer zu werden. Was seine Verbindung zur „Frankfurter Schule“ anbelangt, so wurde der Jude Theodor Wiesengrund Adorno von Tillich habilitiert; mit Max Horkheimer veranstaltete er Seminare. Während seiner Frankfurter Zeit hat sich Tillich z. B. dem Verhältnis von Protestantismus und Profanität zugewandt: „Das Heilige liegt nicht außerhalb des Profanen, sondern in seiner Tiefe. Es ist der schöpferische Grund des Profanen“; Kultur ist ihrer Substanz nach Religion. 1929 schloß sich Tillich der SPD an, aus der er 1933 austrat. Dennoch mußte er am 10.5.1933 mit ansehen, wie auf dem Frankfurter Römer auch ein Exemplar seines Buches „Die sozialistische Entscheidung“ verbrannt wurde. Zusammen mit Max Horkheimer wurde Tillich am 13.4.1933 „beurlaubt“ und am 20.12.1933 aus dem Staatsdienst entlassen. Er emigrierte in die USA, wo er 1965 starb.
Auch den großen katholischen Theologen Karl Rahner SJ, der sich 1937 in Innsbruck für katholische Dogmatik habilitierte, zeichnet eine ähnliche Breite des Wissens und Denkens aus. 1964 erhielt er den „Prestigelehrstuhl“ Romano Guardinis (Lehrstuhl für christliche Weltanschauung) in München. Seine akademische Lehrtätigkeit und sein Wirken als Konzilstheologe machten ihn schon in jungen Jahren weit über Deutschland und Europa hinaus bekannt.
Ich beginne mit einer etwas vereinfachten Darstellung der sogenannten 'Letzten Dinge' (Eschata) in der traditionellen (neu)scholastischen Theologie (Vgl. Siegfried Meier, Sterben, Tod und Auferstehung, in: Schulinformationen, Paderborn, 30. Jg., Nr. 2, 2000, S. 61ff.). Diese geht davon aus, daß sich im Tod die unsterbliche Seele vom sterblichen Leib trennt. Der Leichnam verfällt, die Seele hingegen kommt ganz allein vor das Gericht Gottes. Daher nennt man dieses Gericht auch das besondere Gericht (iudicium particulare). Derjenige, der im Zustand der Heiligkeit verstorben ist und alle zeitlichen Sündenstrafen schon in diesem Leben abgebüßt hat, dessen Seele kommt sofort in den Himmel. Stirbt hingegen ein Mensch im Zustand der Todsünde, beginnt durch den Richterspruch Gottes die sofortige Verdammnis in der Hölle. Der mittelmäßige Mensch, der weder als Heiliger noch als Todsünder gestorben ist, muß eine Zeit der Läuterungsqualen im Fegefeuer erleiden. Schwere und Menge der noch nicht abgebüßten Sündenstrafen bestimmen die Dauer und Intensität des dortigen Aufenthaltes. Erst danach kann die Seele in den Himmel gelangen. Am letzten Tag der Weltgeschichte, dem sogenannten 'Jüngsten Tag', kommt es zur Auferstehung der Toten. Das bedeutet, daß die Seelen mit dem toten Körper wieder zu lebendigen Menschen vereinigt werden. Dann wird Gericht gehalten über den ganzen Menschen. Dieses Gericht wird daher als das allgemeine Gericht (iudicium universale) bezeichnet. Nach diesem Gericht gibt es nur noch Himmel und Hölle.
Was das Fegefeuer und den damit verbundenen Ablaß anbelangt, so haben sich die Reformatoren mit diesem Bild von Tod und Auferstehung kritisch auseinandergesetzt, was aber Gemeinsamkeiten, die auch im Blick auf gemeinsames Erbe antiker Philosophie begründet sind, nicht ausschließt...
Jubiläen haben es in sich! In diesem Jahr werden wir vor allem an den großen Philosophen Immanuel Kant erinnert, der am 12.2.1804 in Königsberg in Preußen gestorben ist. Sein Denkmal am Königsberger Dom hat den Krieg und auch die Russen überstanden. Am populärsten ist bis heute Kants Erläuterung von „Aufklärung“: „Aufklärung ist der Ausgang des Menschen aus seiner selbst verschuldeten Unmündigkeit. Unmündigkeit ist das Unvermögen, sich seines Verstandes ohne Leitung eines anderen zu bedienen. Sapere aude! Habe Mut, dich deines eigenen Verstandes zu bedienen! ist also der Wahlspruch der Aufklärung!“1 Nicht nur, daß die 1784 niedergeschriebene Abhandlung Kants nicht am Anfang der deutschen Aufklärung steht, sondern eher ihr Schwanengesang ist: In der Regel wird auch verschwiegen, daß der Autor selbst die prinzipielle Gültigkeit dieser Sätze entscheidend einschränkte, wenn er am Schluß seiner Abhandlung alle radikalen Konsequenzen ausdrücklich verwarf und das Grundgesetz des friderizianischen Preußen pries: „Räsonniert, soviel als ihr wollt, und worüber ihr wollt, nur gehorcht!“ Kant hat den Angriff Napoleons auf Europa, den Zusammenbruch Preußens und Österreichs nicht mehr erlebt. So ist ihm die bittere Erfahrung erspart geblieben, daß von den Idealen einer Revolution meistens nur verwirklicht wird, was machtpolitisch brauchbar ist...
Anonyme Protestanten?
(2014)
Selbst bei theologisch so verschiedenen Charakteren wie Dorothee Sölle und Paul Tillich wurden religionskulturelle Unterschiede zwischen Personen durch den Verweis auf Gemeinsamkeiten in ihrem Leben und Handeln als „anonyme Christen“ zumindest relativiert, wenn nicht gar durch diese umfassende Kategorie ganz eingezogen. Differenzen zwischen Selbsteinschätzung und Fremdwahrnehmung der betreffenden Personen spielen dann kaum noch eine wesentliche Rolle.
Im Rückblick auf zwei Jubiläen soll im Folgenden die Brauchbarkeit der Kategorie „Anonyme Christen“ am Sonderfall „Anonyme Protestanten“ überprüft werden.
Der Titel bedarf einer besonderen Begründung! 800 Jahre Elisabeth von Thüringen: Katholische und Evangelische Kirche begehen z. B. in Hessen mit einer Fülle von Veranstaltungen 2007 das „Elisabethjahr“. Die Ev. Kirche in Kurhessen-Waldeck und die Ev. Kirche in Hessen und Nassau haben unter dem Titel „Krone, Brot und Rosen. 800 Jahre Elisabeth von Thüringen“ einen umfangreichen Veranstaltungskalender vorgelegt. Bereits an ihrem 775. Todestag lassen die hessischen Landeskirchen und Bistümer in ökumenischer Eintracht, aber mit unterschiedlicher Akzentuierung das Elisabethjahr beginnen. „In einem war man sich schnell einig: Elisabeth kann sicher nicht als moderne Sozialapostolin gedeutet werden, die auf die reine Mitmenschlichkeit setzte; dafür waren ihre Christusfrömmigkeit und ihre Christusnachfolge zu stark ausgeprägt; sie verband praktizierte Caritas mit tiefer Gottesbeziehung. Es gab aber ein hartes Ringen um ein gemeinsames Erscheinungsbild des Gedenkens. Das Attribut ‚heilig‘ war für die evangelische Seite nicht akzeptabel. Für Protestanten ist die fürstliche Wohltäterin nur Elisabeth von Thüringen, und so steht es auch auf dem Logo für evangelische Gedenkveranstaltungen. Auf dem Logo für ökumenisch verantwortete Veranstaltungen wird kompromißhaft zusammengefügt: ‚Heilige Elisabeth. Elisabeth von Thüringen‘ “ (Gernot Facius). Wenn ich im Folgenden weiter von der „Hl. Elisabeth“ rede, soll dieser Hintergrund nicht vergessen werden.
Spuren der Elisabeth-Verehrung finden sich aber nicht nur in Deutschland und in Ungarn. Auch in Italien, Portugal, Tschechien, ja sogar in Skandinavien und den baltischen Ländern erinnert man sich an die deutsche Nationalheilige des Mittelalters...
"Du sollst dir kein Bildnis noch irgendein Gleichnis machen, weder des, das oben im Himmel, noch des, das unten auf Erden, oder des, das im Wasser unter der Erde ist" (Exodus 20,4): Dieses Gebot aus dem Dekalog hat die Religions- und Kulturgeschichte immer wieder berührt. Vor allem der reformierte Protestantismus rühmt sich seiner 'Bilderlosigkeit'. Was sind aber 'Bilder'? ...
Mohammad Arkoun (٭1928, Algeria; †2010, Paris) was an influential Muslim intellectual and particularly concerned with - amongst a profound spectrum of scholarly interests – reforming the academic study of Islamic societies. Trained at the University of Algiers (Faculty of Philology) he ventured off to lecture Arab language and literature at the Sorbonne. His engagement with philosophy and sociology led in 1968 to his PhD at the Sorbonne through a work on Ibn Miskawayh’s ethics...
This exploration into Arkoun’s stances on the Quran looks onto the genesis of the Quran, the notion of the Quran as the ‘deliverer of truth’, and with that, its significane for the ‘being in the world’ of Muslim societies. I will also point out some crucial difficulties in the study of Arkoun’s views on the Quran as well as their implications for the study of Islamic cultures.
The Crusade movement is one of the most important occurrences of medieval history. It took place throughout two centuries in the Levant and affected both Muslims and Crusaders and in turn changed the way in which West and East related to one another. When the Crusaders took control of the Holy Land and many Islamic cities in the Levant, they transferred their feudal European system there. They established four main fiefdoms or lordships, Jerusalem, Edessa, Antioch and Tripoli. In addition, there were another twelve secondary fiefdoms, of which Tibnīn was one. Tibnīn was called “Toron” by the Crusaders. Once the Crusaders had captured Tibnīn, they began building its fortified castle, from which the fief of Tibnīn gained its importance throughout the period of the Crusades.
This paper traces the military role of Tibnīn and its rulers in the Latin East against the Muslims until 1187/ 583. Tibnīn played a key role in overcoming the Muslims in Tyre and controlled it in 1124. It also played a vital role in the conflict between Damascus and the Kingdom of Jerusalem. Tibnīn participated in defending Antioch, Banyas, Hebron and Transjordan several times. Furthermore, its soldiers and Knights joined the army of the Kingdom of Jerusalem to capture Ascalon in 1153, and joined the campaigns of Amaury I, King of Jerusalem, against Egypt from 1164 to1169. The military situation of Tibnīn under the rule of the royal house until its fall to the Muslims in 1187/ 583 will be studied as well.

In this essay, one of the most serious problems highlighted with respect to contemporary Iranians, who are mostly known as Shi‘ite-Perso (Shi‘ite-Persian) citizens of Iran, and what their view toward abusing wine and opium is. On one hand, the wealthy Persian literature is full of poems, narrations and notes with reference to wine and opium, while on the other hand, many parts of Shi‘ite-Islamic thought deem wine unclean and illegal, and abusing opium is forbidden except under certain [hard-fulfilling] conditions. Hereby, in this essay the aim is to express why the question “are drinking wine and abusing opium known as addiction or literal culture?” is suspended throughout the young Iranian generation. In this regard, the standpoints of Persian poets and Iranian religious figures towards wine and opium will be considered.
Motivated by the question whether sound and expressive applicative similarities for program calculi with should-convergence exist, this paper investigates expressive applicative similarities for the untyped call-by-value lambda-calculus extended with McCarthy's ambiguous choice operator amb. Soundness of the applicative similarities w.r.t. contextual equivalence based on may-and should-convergence is proved by adapting Howe's method to should-convergence. As usual for nondeterministic calculi, similarity is not complete w.r.t. contextual equivalence which requires a rather complex counter example as a witness. Also the call-by-value lambda-calculus with the weaker nondeterministic construct erratic choice is analyzed and sound applicative similarities are provided. This justifies the expectation that also for more expressive and call-by-need higher-order calculi there are sound and powerful similarities for should-convergence.
The pi-calculus is a well-analyzed model for mobile processes and mobile computations.
While a lot of other process and lambda calculi that are core languages of higher-order concurrent and/or functional programming languages use a contextual semantics observing the termination behavior of programs in all program contexts, traditional program equivalences in the pi-calculus are bisimulations and barbed testing equivalences, which observe the communication capabilities of processes under reduction and in contexts.
There is a distance between these two approaches to program equivalence which makes it hard to compare the pi-calculus with other languages. In this paper we contribute to bridging this gap by investigating a contextual semantics of the synchronous pi-calculus with replication and without sums.
To transfer contextual equivalence to the pi-calculus we add a process Stop as constant which indicates success and is used as the base to define and analyze the contextual equivalence which observes may- and should-convergence of processes.
We show as a main result that contextual equivalence in the pi-calculus with Stop conservatively extends barbed testing equivalence in the (Stop-free) pi-calculus. This implies that results on contextual equivalence can be directly transferred to the (Stop-free) pi-calculus with barbed testing equivalence.
We analyze the contextual ordering, prove some nontrivial process equivalences, and provide proof tools for showing contextual equivalences. Among them are a context lemma, and new notions of sound applicative similarities for may- and should-convergence.
The Paddys River Wetlands in the New South Wales Southern Highlands, southwest of Sydney, are characterised by several watercourses with associated swamps (fens), some of which, on Forestry Corporation of NSW land, have been the focus for removal of Pinus radiata wildings by the Penrose Swamps Conservation Group. In this study we map a population of Eucalyptus aquatica trees in one of these swamps perched above Paddys River (latitude 34.65575o S, longitude 150.21831o E; 600 m elevation). Eucalyptus aquatica is geographically restricted to the Paddys River area and is listed as a threatened species at state and national levels. New findings on the physical characteristics of the swamp in relation to the bedrock geology, stream geomorphology, peat development and the main native plant species, are presented. The occurrence of clumps of Eucalyptus aquatica appears to be independent of the type or thickness of the growing substrate. Rather it is suggested that a continuous supply of water and the shelter afforded by the narrow valley may be key factors determining the distribution of the trees at the study site. An on-going programme of research is underway to study other occurrences of Eucalyptus aquatica.
The Queensland Herbarium Regional Ecosystem Survey and Mapping (QHRESM) program has contributed almost 90000 (89389) specimens to the Queensland Herbarium in Brisbane accounting for 28% of the specimens added to the Herbarium between 1970 and 2011. These specimens have been collected across all bioregions and vegetation communities in Queensland in a systematic sampling program driven by the requirement to sample comprehensively all vegetation communities. The QHRESM’s Queensland Herbarium (BRI) specimens represent more than 79% of the native, and 73% of the naturalised vascular flora of Queensland, as well as making valuable contributions to the bryophytes, lichens and liverworts collections. The data and specimens collected enhance our ability to assess local, state and continental-scale plant diversity, and will be used by botanists, ecologists, governments, business and the public for long into the future.
