Recent evidence from our lab indicates that LTP shares an important property with memory consolidation: it is consolidated by natural reinforcement. Nevertheless, the hypothesis, that LTP-like mechanisms or other forms of enhanced synaptic efficacy are basic elements in learning is not unequivocally supported. Skepticism aside, LTP is an accessible experimental model that is optimally equipped for the investigation of the cellular and molecular machinery involved in synaptic weight changes.

Organizations increasingly use technology-mediated interviews. However, only limited research is available concerning the comparability of different interview media and most of the available studies stem from a time when technology-mediated interviews were less common than in the present time. In an experiment using simulated selection interviews, we compared traditional face-to-face (FTF) interviews with telephone and videoconference interviews to determine whether ratings of interviewees’ performance, their perceptions of the interview, or their strain and anxiety are affected by the type of interview. (...) Before participating in the actual interview, participants had a more positive view of FTF interviews compared to technology-mediated interviews. However, fairness perceptions did not differ anymore after the interview. Furthermore, there were no differences between the three interview media concerning psychological and physiological indicators of strain or interview anxiety. Nevertheless, ratings of interviewees’ performance were lower in the technology-mediated interviews than in FTF interviews. Thus, differences between different interview media can still be found nowadays even though most applicants are much more familiar with technology-mediated communication than in the past. The results show that organizations should take this into account and therefore avoid using different interview media when they interview different applicants for the same job opening. (shrink)

This paper deals with EMIL-S, a software tool box which was designed during the EMIL project for the simulation of processes during which norms emerged in an agent society. This tool box implements the cognitive architecture of normative agents which was designed during the EMIL project which is also discussed in other papers in this issue. This implementation is described in necessary detail, and two examples of its application to several different scenarios are given, namely a scenario in which persons (...) involved in micro finance are simulated and learn how to sanction free riders and how to learn from these sanctions, and a scenario in which simulated persons move through a simulated airport where they more often than not have to wait in queues and learn how to behave properly in queues.

Prior research suggests that interviewers play an important role in representing their organization and in making the interview a pleasant experience for applicants. This study examined whether impression management used by interviewers (organization-enhancement and applicant-enhancement) is perceived by applicants, and how it influences applicants’ attitudes, intentions, and emotions. Adopting a signaling perspective, this article argues that applicants’ positive attitudes and intentions towards the organization increase if interviewers not only enhance the organization, but if the signals they sent (i.e., organization-enhancement) are (...) actually received by the applicant. Similarly, applicants’ positive emotions should increase if interviewers not only enhance the applicant, but if the signals they send (i.e., applicant-enhancement) are actually received by the applicant. A field study which involved video coding interviewers’ impression management behavior during 153 selection interviews and pre- and post-interview applicant surveys showed that the signals sent by interviewers during the interview were received by applicants. In addition, applicants rated the organization’s prestige and their own positive affect after the interview more positively when they perceived higher levels of organization-enhancement during the interview. Furthermore, applicants reported more positive affect and interview self-efficacy after the interview when they perceived higher levels of interviewer applicant-enhancement. We also found an indirect effect of interviewers’ organization-enhancement on organizational prestige through applicants’ perceptions of organization-enhancement as well as indirect effects of interviewers’ applicant-enhancement on applicants’ positive affect and interview self-efficacy through applicants’ perceptions of applicant-enhancement. Our findings contribute to an integrated understanding of the effects of interviewer impression management and point out both risks and chances in selling and smooth-talking towards applicants.

In many countries consumers have shown an increasing interest to the way in which food products are being produced. This study investigates Chinese consumers’ attitudes towards different pig production systems by means of a conjoint analysis. While there has been a range of studies on Western consumers’ attitudes to various forms of food production, little is known about the level of Chinese consumers’ attitudes. A cross-sectional survey was carried out with 472 participants in 6 Chinese cities. Results indicate that Chinese (...) consumers prefer industrial pig production systems, where traditional pig breeds are raised, over large-scale and small family farms. Farms with maximum attention to food safety, which furthermore can provide lean meat with consistent quality, are also preferred. Imported pig breeds and tasty but variable meat were rejected. A 3-cluster solution found that consumers from cluster 1 focus almost exclusively on the food safety aspect (food safety focused). Consumers from cluster 2 (indifferent) show weak overall attitudes to pig production systems in general. Cluster 3 (industrial production oriented) stands out by being very positive about industrial, large-size farms and consistent quality. From a Chinese consumer’s perspective, the industrial approach seems to represent values such as achievement and evolution, as well as quality and safety, since pig production is moving away from low-cost, low-quality, and low-safety family-scale systems. A complex set of rural and environmental development, quality aspects, and food safety measures are challenges that must be met by the stakeholders of pig production systems in China. (shrink)

Anthropologische Medizin (AM) i. S. Viktor von Weizsäckers sieht grundlegende Selbsterfahrungen des Menschen (Leiblichkeit, Zeitlichkeit u. a.) für den Umgang von Arzt und Krankem als zentral. Sie ist offen für die leiblich-seelische Betroffenheit, für die mögliche Stellvertretung des Physischen und Psychischen und sieht den Kranken als Subjekt und Objekt, das sich selbst zugleich Subjekt und Objekt ist. „Umgangslehre“ kennzeichnet AM als Handlungswissenschaft, die der „Doppelstruktur sachlicher und personaler Entsprechung von Mensch in Not und Mensch als Helfer bzw. Krankheit und Medizin“ (...) folgt. Sie unterscheidet Krankheit und Kranksein sowie klinische und (natur-)wissenschaftliche Objektivität. Lebensweltliche und psychosoziale Faktoren beeinflussen das Kranksein. Als Umgangslehre setzt anthropologisch-klinische Wissenschaft „an die Stelle der Objektivitätslehre der Erkenntnis eine personalistische […] Erkenntnislehre“, die auch ihre methodischen, handlungslogischen Sach- und Wertbegründungen reflektiert. Brücken zwischen AM und dem gegenwärtigen Ethikdiskurs werden skizziert. (shrink)

Der Mathematiker Erhard Weigel (1625-1699) gilt bisher als einer der bedeutendsten deutschen Vertreter der sog. "Fruehaufklärung". Dieser Band hinterfragt nun diesen traditionellen und deshalb allzu bequemen philosophiegeschichtlichen Begriff nach seiner Erklärungsfunktion innerhalb der modernen Wissenschaftsgeschichte. In komparatistischer Sicht auf die deutsche Universitätslandschaft nehmen die Beiträger den institutionellen Rahmen und seine konkreten Auswirkungen auf den Lehrbetrieb in den Blick, um die Bedingungen des damaligen Wissenschaftsverständnisses und seiner Entwicklungsrichtungen zu untersuchen. Im Fokus stehen die Verwandlungen der aristotelischen Basis des Wissenschaftsverständnisses und was (...) sich damalige Universitätslehrer als Autoren explizit (z.B. in Form wissenschaftstheoretischer Schriften und Lehrbuecher) oder implizit (z.B. in Form der von ihnen praktizierten Wissenschaft) unter Wissenschaft vorgestellt und ihrem gelehrten Publikum vermittelt haben.

Academic performance enhancement or cognitive enhancement (CE) via stimulant drug use has received increasing attention. The question remains, however, whether CE solely represents the use of drugs for achieving better academic or workplace results or whether CE also serves various other purposes. The aim of this study was to put the phenomenon of pharmacological academic performance enhancement via prescription and illicit (psycho-) stimulant use (Amphetamines, Methylphenidate) among university students into a broader context. Specifically, we wanted to further understand students’ experiences, (...) the effects of use on students and other factors, such as pressure to perform in their academic and private lives. (shrink)

We explore the complexity of Sacks’ Splitting Theorem in terms of the mind change functions associated with the members of the splits. We prove that, for any c.e. set A, there are low computably enumerable sets $A_0\sqcup A_1=A$ splitting A with $A_0$ and $A_1$ both totally $\omega ^2$ -c.a. in terms of the Downey–Greenberg hierarchy, and this result cannot be improved to totally $\omega $ -c.a. as shown in [9]. We also show that if cone avoidance is added then there (...) is no level below $\varepsilon _0$ which can be used to characterize the complexity of $A_1$ and $A_2$. (shrink)

We solve a longstanding question of Soare by showing that if ${\mathbf d}$ is a non-low $_2$ computably enumerable degree then ${\mathbf d}$ contains a c.e. set with no r-maximal c.e. superset.

SummaryThe article takes issue with W. G. Runciman's contention, in Great Books, Bad Arguments, that modern political development has moved beyond both theory and practice of governance by a sovereign power over subjects as expounded in Hobbes's Leviathan. Runciman's allegations that Hobbes overrates education, that he fails to recognise the potential for dissent and revolt in a polity under a sovereign, and that he ignores society's pre-political scope and its post-absolutist, eventually democratic prospects, are checked against the text and argument (...) of Leviathan. Runciman's contention that government without subjection has been achieved in modern constitutions is confronted with Hobbes's resistance. (shrink)

Two librettos are examined, one of them baroque and the other contemporary, in which the character Socrates plays the major role. The libretto La patienza di Socrate con due moglie, written by N. Minato for A. Draghi (1680) and later reelaborated by G.P. Telemann for his opera Der geduldige Sokrates (1721), is based on an imaginary anecdote that dates back to antiquity, according to which Socrates was married to two wives, Xanthippa and Myrto. In the libretto written by E. Krenek (...) for his opera Pallas Athene weint (first production 1955), the end of the Peloponnesian War is transformed into a mirror of the fascist dictatorship of Adolf Hitler and of the time of cold war. At the center of the action is Socrates, fighting in vain against tyranny and lack of political freedom, and at the end he will be a victim of this struggle. (shrink)

BackgroundBiobanking biospecimens and consent are common practice in paediatric research. We need to explore children and young people’s (CYP) knowledge and perspectives around the use of and consent to biobanking. This will ensure meaningful informed consent can be obtained and improve current consent procedures.MethodsWe designed a survey, in co-production with CYP, collecting demographic data, views on biobanking, and consent using three scenarios: 1) prospective consent, 2) deferred consent, and 3) reconsent and assent at age of capacity. The survey was disseminated (...) via the Young Person’s Advisory Group North England (YPAGne) and participating CYP’s secondary schools. Data were analysed using a qualitative thematic approach by three independent reviewers (including CYP) to identify common themes. Data triangulation occurred independently by a fourth reviewer.ResultsOne hundred two CYP completed the survey. Most were between 16–18 years (63.7%, N = 65) and female (66.7%, N = 68). 72.3% had no prior knowledge of biobanking (N = 73).Acceptability of prospective consent for biobanking was high (91.2%, N = 93) with common themes: ‘altruism’, ‘potential benefits outweigh individual risk’, 'frugality', and ‘(in)convenience’.Deferred consent was also deemed acceptable in the large majority (84.3%, N = 86), with common themes: ‘altruism’, ‘body integrity’ and ‘sample frugality’. 76.5% preferred to reconsent when cognitively mature enough to give assent (N = 78), even if parental consent was previously in place. 79.2% wanted to be informed if their biobanked biospecimen is reused (N = 80).ConclusionProspective and deferred consent acceptability for biobanking is high among CYP in the UK. Altruism, frugality, body integrity, and privacy are the most important themes. Clear communication and justification are paramount to obtain consent. Any CYP with capacity should be part of the consenting procedure, if possible. (shrink)

Apresenta-se a tradução para o português das páginas iniciais da nova biografia de G. W. F. Hegel, da autoria de Klaus Vieweg. Nestas páginas, Vieweg expõe um panorama geral da vida de Hegel, bem como as chaves interpretativas que permitem relacionar a vida com a obra. Apresenta-se, assim, uma visão coerente e pormenorizada do percurso bio-bibliográfico do filósofo, da sua inserção na sua época, assim como um esboço muito geral da recepção de Hegel, tanto pelos seus contemporâneos como na (...) atualidade. Desmontam-se além disso diversos preconceitos e erros, por vezes grosseiros, de interpretação que se repetiram nos últimos dois séculos sobre o filósofo de Estugarda. (shrink)

Related essays contextualise the typescript drawing on a variety of backgrounds (...) from mathematics and engineering to philosophy and sociology. (shrink)

Can one speak philosophically of a justified limitation of freedom? Hegel’s logically founded definition of free will and his understanding of right and duty can contribute to a clarification of the concept of freedom. Important is a precise differentiation between freedom and caprice (Willkür) – the latter being a necessary but one-sided element of the free will. In caprice, the will is not yet in the form of reason. Rational rights and duties are not a restriction of freedom. Insofar as (...) individual rights can collide (e. g. in emergency situations), there can be a temporary and proportionate restriction of certain rights in favour of higher rights, such as the right to life. Dictatorships are instances of capricious rule which restrict freedom; the rationally designed state, by contrast, restricts only caprice. What is tobe defined are the duties and the rights of the state and the duties and the rights of the citizens. (shrink)

There are about 100 different contradictory definitions of life. The definition of life based on symbiosis that is presented here differs fundamentally from them; it gives life a value. So this definition offers a basis for ethical and legal action e.g. in organ transplants. It is based on principles and is not an ad hoc model: Significant processes for life are basis for a theoretical concept. Quality criteria for definitions are employed to control the concept. There is a graduation, not (...) a clear division, between inanimate and animate. The graduation is based on the amount of symbiosis to be found. Life is based on symbiosis. The ideas of “ethics” and “reality” are considered in the context of this definition. (shrink)
