Syllogisms (e.g. “All A are B; All B are C; What is true about A and C?”) are a long‐studied area of human reasoning. Riesterer, Brand, and Ragni compare a variety of models to human performance and show that not only do current models have a lot of room for improvement, but more importantly a large part of this improvement must come from examining individual differences in performance.

After 100+ years of studying syllogistic reasoning, what have we learned? Well, Riesterer and colleagues suggest that we have learned to throw away most of the data! If that seems like a bad idea to you then, be assured, that the authors agree with you. The sad fact is that the conclusion of “No Valid Conclusion” (NVC) is one of the most frequently selected responses in syllogistic reasoning but these “majority data” have been ignored by most researchers. Riesterer and colleagues (...) introduce heuristic rules for predicting NVC and provide directions to modelers on how to up their game. (shrink)

The formation of blood vessels within the vascular system entails a variety of cellular processes, including proliferation, migration and differentiation. In many cases, these diverse processes need to be finely coordinated among neighbouring endothelial cells in order to establish a functional vascular network. For instance, during angiogenic sprouting specialized endothelial tip cells follow guidance cues and migrate extensively into avascular tissues while trailing stalk cells must stay connected to the patent blood vessel. The vascular endothelial growth factor (VEGF) and Notch (...) signalling pathways have emerged as the major players in governing these different cellular behaviours. In particular, recent work indicates an important role for Notch signalling in determining how an endothelial cell responds to VEGF. In this review, we provide an overview of these biochemically distinct pathways and discuss how they may interact during endothelial cell differentiation and angiogenesis.

In 1922, philosopher Jakob Klatzkin and Zionist politician and later president of the World Jewish Congress, Nahum Goldmann founded the Eschkol publishing company in Berlin and began their major work on the Encyclopaedia Judaica. Eschkol was active during the Weimar Republic, where culture and politics were shaped by a Jewish renaissance and by the sustained migration of Jews from Eastern Europe. Most of the publisher’s books and brochures show emblematic historical ruptures and the migration of knowledge to new spaces, languages, (...) and cultures. This article analyzes Eschkol’s publications and cultural agenda from the perspective of a material culture of printed works, and focuses on its textbook program. It concentrates the discussion on the historian Simon Bernfeld and Jakob Klatzkin, two formative scholars of that period. (shrink)

Name der Zeitschrift: Naharaim Jahrgang: 12 Heft: 1-2 Seiten: 3-8.

Vigilanz wird alltäglich ausgeübt, etwa im Bereich der Sicherheit, des Rechts, der Religionen oder auch der Öffentlichen Gesundheit: überall dort, wo wir auf etwas achten, gegebenenfalls auch etwas tun oder melden sollen. Der Münchner SFB 1369, in dem dieser Band entstanden ist, untersucht die Geschichte, kulturellen Varianten und aktuellen Formen dieses Phänomens nichtinstitutioneller, aber doch hochgradig funktionaler Wachsamkeit. Der erste Band der Publikationsreihe,Vigilanzkulturen' widmet sich der zeitlichen Dimension von Vigilanz. So wie menschliche Aufmerksamkeit erheblichen Schwankungen unterliegt, ist auch Wachsamkeit zeitlich (...) instabil. Die hohe physiologisch-kognitive Intensität von Wachsamkeit lässt sich nur schwer auf Dauer stellen. Wird über längere Zeit hinweg ein ereignisloses oder unstrukturiertes Geschehen beobachtet, sinkt die Aufmerksamkeit oder richtet sich auf anderes. Kulturelle Anleitungen zur Wachsamkeit arbeiten daher in der Regel selbst mit zeitlichen Strukturen: mit Rhythmisierungen, Habitualisierungen oder Dramatisierungen. Sie geben vor, in welcher Abfolge Wachsamkeit herauf- oder herabgestuft werden soll oder sie variieren denkbare Gefahren. Sie arbeiten mit natürlichen Zeitverläufen (wie Tag und Nacht, Licht und Dunkelheit), die sie, kulturell überformt, nutzbar machen. Darüber hinaus können auch Techniken und Medien helfen, Wachsamkeit zu verstetigen. Der Band untersucht diese zeitliche Gestaltung der Wachsamkeit anhand historisch spezifischer Konstellationen. Er versammelt Beiträge aus unterschiedlichen Disziplinen wie Geschichte, Ethnographie, Kunstgeschichte, Literatur- und Medienwissenschaft, um die Zeiten der Wachsamkeit zu erforschen. (shrink)

This brief survey of Professor Karl LOwith's analysis of the modem histori cal consciousness is the outgrowth of a year's study at the University of Heidelberg while Professor L6with was still an active member of the faculty. An early version, in the form of a dissertation, was submitted to the History Department of Wayne State University, Detroit, Michigan, U.S.A. Numerous friends and colleagues have helped me at various stages of this work and I am indebted to them even though I (...) cannot name them all indi vidually. However special thanks must be accorded to Professor W. J. Bos senbrook of Wayne State University for introducing me to the entire prob lem of anti-historicism and to Professor LOwith's work. I am also greatly indebted to Professor John Barlow of Indiana University for his patient assistance with the translations, however the final responsibility for all renditions rests, of course, solely with the author.

Corruption continues to be a considerable challenge for internationally active companies. In this article, we examine personal and socioenvironmental antecedents of corrupt behavior in organizations. In particular, we aim to illuminate the links between Machiavellianism, on-the-job experience with corrupt behavior at work, neutralization, and the attitude of business professionals toward corruption. The empirical analysis is based on the responses of 169 professionals. At first, a positive relationship between both Machiavellianism and on-the-job experience and the acceptance of corruption appears in the (...) model. However, an in-depth mediation analysis shows that neutralization is the keystone linking both Machiavellianism and on-the-job experience to the likelihood to condone corruption. Based on these results, we offer avenues for further research and implications for practitioners. (shrink)

Die Studie ist am Schnittpunkt von Geschichts-, Sprach- und Kulturwissenschaften angesiedelt und behandelt die Jahre 1893-1933. Anhand einschlägiger Alltagsquellen werden liberaljüdische, zionistische und antisemitische Einstellungen zu Sprache generell sowie zu den Einzelsprachen Deutsch, Jiddisch und Hebräisch im diskursiven Spannungsfeld von Angriff und Apologie untersucht. Dabei versucht die Untersuchung auch Antworten zu geben auf die Frage, wie das kulturell fruchtbare Verhältnis zwischen Juden und Deutschen letztlich in die Katastrophe der nationalsozialistischen Judenvernichtung münden konnte.

Biobanks, collecting human specimen, medical records, and lifestyle-related data, face the challenge of having contradictory missions: on the one hand serving the collective welfare through easy access for medical research, on the other hand adhering to restrictive privacy expectations of people in order to maintain their willingness to participate in such research. In this article, ethical frameworks stressing the societal value of low-privacy expectations in order to secure biomedical research are discussed. It will turn out that neither utilitarian nor communitarian (...) or classical libertarian ethics frameworks will help to serve both goals. Instead, John Rawls’ differentiation of the “right” and the “good” is presented in order to illustrate the possibility of “serving two masters”: individual interests of privacy, and societal interests of scientific progress and intergenerational justice. In order to illustrate this counterbalancing concept with an example, the five-pillar concept of the German Ethics Council will be briefly discussed. (shrink)

In recent years consumer law has come more and more into the focus of legislation within the EU. One of the EU’s key objectives, completing the final stage of the internal market, is to place consumer rights in the centre of it. Following the adaption of various consumer law measures for some decades, the EU has undertaken a thorough review of its consumer acquis. After years of consultations, the Consumer Rights Directive 2011/83/ EU, which was supposed to set new standards (...) of consumer protection, came into force and will have to be implemented by the Member States by 13 December, 2013. Renouncing its principal practice of minimum harmonisation in the area of consumer law, i.e. allowing Member States on the basis of Directives to adopt more protective rules, the EU legislator now turned to a targeted full harmonisation approach by means of the Consumer Rights Directive, aiming at increasing the consumer protection across the EU by bringing together the currently distinct laws for distance selling and off-premises contracts as well as other types of consumer contracts in a single instrument. The article briefly introduces the background of the Directive and discusses the shift in means of harmonisation concepts. Then, it analyses the scope, concepts and content of the Directive, which mainly brings considerable reforms in the areas of information requirements and the right of withdrawal. Taking into account the Directive’s improvements and shortcomings, conclusions are drawn that further harmonisation and a uniform and universally applicable set of European consumer rights are needed.

Fifty years ago, on 12 September, 1963, the association agreement between the European Economic Community (EEC) and Turkey was signed in Ankara. However, in contrast to many other countries who applied later on, Turkey has not yet become a member of the EU. Nevertheless, Turkey’s candidacy to join the EU is still one of the most considerable and controversial topics within the European political arena. Within the accession negotiations, apart from human rights and the Kurdish and the Cypriot issues, one (...) of the greatest challenges to Turkey’s successful candidacy is the issue of respect for and protection of minorities. It might indeed represent an unsolvable problem, which will ultimately block Turkey joining the EU. Neither the EU nor Turkey has really come to terms or dealt with what the EU sees as an “unsatisfactory” protection of minorities in Turkey. What lies at the root of this disagreement is what the term “minority” actually means. Due to Turkey’s own nation state concept as being a united and undivided country and to the terms of the Treaty of Lausanne signed in 1923, which defined Turkey as a nation, the country only recognises non-Muslim minorities. Moreover, contrary to the wording of the minority protection clauses in the Treaty of Lausanne, Turkey restricts its recognition of non-Muslim minorities only to the Greek, Armenian and Jewish religious populations. Although being a non-Muslim group as well, the Assyrians are excluded from the Turkish concept of minorities and, therefore, also from minority protection. In contrast to that, the EU’s concept of minority includes ethnic, linguistic and religious minorities, which means that according to the EU’s concept of minorities, also ethnic minorities like the Kurds, linguistic minorities like the Laz and religious minorities like the Alevis are included in the term “minority” and, therefore, these minorities should benefit from specific minority protection rights. To find a common basis for discussing the unsatisfactory issue of minority rights in Turkey, the concept of “ethnic groups” is introduced by the author as the most promising approach to deal with this unreconciled conceptual difference. According to this concept, ethnic groups could form a sub-identity of Turkishness and help build a legal basis to the treatment of minority groups founded on human rights, which would be compatible with both Turkish and EU Law.

In the concept of revolution there are two essential elements of political life. The first one is the fragility and sensitivity of the world of things created by human beings, lack of durability and strong support of the political order. The other element is the human ability to create and build a new order with hope for its survival. However, a more adequate approach to understand these elements is conceptualization of politics and political actions that anticipate the opening of the (...) public sphere to the traditional and religious arguments, and also to the problems of dignity of human work. What is also important is the awareness that it requires redefinition of the anthropological assumptions and a radical broadening of understanding how humans act according to what Hannah Arendt proposes. Moreover, it is important to understand that the redefinition means something more than just retouching as it is defined by Habermas, who believes in “laic communicative power” even in spite of mentioning “complementary learning process” of religion and secular outlook from yourself.

The Findlay-Walker model does not consider saccades generated by auditory targets or nontargets (distractors), or by bimodal stimulation. Empirical results suggest that the effects of auditory stimulation cannot easily be incorporated into the model, neither in the WHEN nor in the WHERE system. A two-stage model by Colonius and Arndt gives a quantitative account of the facilitative effects of auditory distractors on saccadic latencies toward visual targets.

We apply three state‐of‐the‐art models for syllogistic reasoning to data from experiments where participants received feedback for their conclusions in order to demonstrate the use of model parameters to derive new hypotheses and present possible explanations for the feedback effect.

We consider various effects that are encountered in matter wave interference experiments with massive nanoparticles. The text-book example of far-field interference at a grating is compared with diffraction into the dark field behind an opaque aperture, commonly designated as Poisson’s spot or the spot of Arago. Our estimates indicate that both phenomena may still be observed in a mass range exceeding present-day experiments by at least two orders of magnitude. They both require, however, the development of sufficiently cold, intense and (...) coherent cluster beams. While the observation of Poisson’s spot offers the advantage of non-dispersiveness and a simple distinction between classical and quantum fringes in the absence of particle wall interactions, van der Waals forces may severely limit the distinguishability between genuine quantum wave diffraction and classically explicable spots already for moderately polarizable objects and diffraction elements as thin as 100 nm.

Archival research can be described as preoccupied with the ontology of data formation and collection in relation to the speaking and writing subject. From its outset, it can be located in the humanistic tradition, which the archival and historical discipline has inherited. Thus, archival research can be described as preoccupied with the ontology of data formation and collection in relation to the speaking and writing subject. At the same time, the archival researcher—the human subject—is produced as the sole source of (...) subjective experiences, consciousness and feelings, and has become the central player in this tradition, embedded in debates over the concept of human autonomy in archival research. Archival researchers—human subjects—should be continually challenged by their own discipline, and by such arguably scientific methods, which often espouse rejecting their ethical commitments to idiosyncrasy, entanglements and the blurring of subject–object binaries. An approach that re-elevates these comm... (shrink)

While pharmaceutical industry involvement in producing, interpreting, and regulating medical knowledge and practice is widely accepted and believed to promote medical innovation, industry-favouring biases may result in prioritizing corporate profit above public health. Using diabetes as our example, we review successive changes over forty years in screening, diagnosis, and treatment guidelines for type 2 diabetes and prediabetes, which have dramatically expanded the population prescribed diabetes drugs, generating a billion-dollar market. We argue that these guideline recommendations have emerged under pervasive industry (...) influence and persisted, despite weak evidence for their health benefits and indications of serious adverse effects associated with many of the drugs they recommend. We consider pharmaceutical industry conflicts of interest in some of the research and publications supporting these revisions, and in related standard-setting committees and oversight panels. We raise concern over the long-term impact of these multifaceted involvements. Rather than accept industry conflicts of interest as normal, needing only to be monitored and managed, we suggest challenging that normalcy, and ask: what are the real costs of tolerating such industry participation? We urge the development of a broader focus to fully understand and curtail the systemic nature of industry’s influence over medical knowledge and practice. (shrink)

‘Individualized medicine’ is an emerging paradigm in clinical life science research. We conducted a socio-empirical interview study in a leading German clinical research group, aiming at implementing ‘individualized medicine’ of colorectal cancer. The goal was to investigate moral and social issues related to physician–patient interaction and clinical care, and to identify the points raised, supported and rejected by the physicians and researchers. Up to now there has been only limited insight into how experts dedicated to individualized medicine view its problems. (...) Interviews with researchers and clinicians were based on a prestructured questionnaire. The content analysis revealed a broad spectrum of opinions. Major findings were disappointments with the limits of the current therapy regimen and clinical practice; problematic impacts on physician–patient relationship; and an informed consent procedure which is mainly based on paternalistic assumptions. According to our analysis, major problems will be uncertainties related to the biomarker's sensitivity and specificity, and the identification of ‘non-responders’. However, the findings also indicate that experts expect evidence-based medicine to replace decisions based on gut feeling or hierarchical structures. (shrink)
