As nation-states make greater efforts to regulate the flow of people on the move—refugees, economic migrants, and international travelers alike—advocates of DNA profiling technologies claim DNA testing provides a reliable and objective way of revealing a person’s true identity for immigration procedures. This article examines the use of DNA testing for family reunification in immigration cases in Finland, Germany, and the United States—the first transatlantic analysis of such cases—to explore the relationship between technology, the meaning of family, and immigration. Drawing (...) on our analyses of archival records, government documents, and interviews with immigration stakeholders, we argue that DNA testing is not conclusive about the meaning of family. While the technology may facilitate decision making for both would-be immigrants and state officials, our study shows hesitancy among the latter to let DNA testing make the final determination. We introduce the concept of social validity—whether the interpretation of test results matches social or political meanings in a given local context—in order to make sense of the complexities and challenges of DNA testing in practice. We show that DNA testing is not just a technology of belonging or a way to claim citizenship rights. It may also enable exclusion and denial of rights. (shrink)

This guest editorial opens with a brief overview of the transformations of medicine and mental health that can be observed since the second half of the twentieth century. New genetics and biotechnologies hold out the promise of overcoming presumed limitations in the field of mental health care, that is, the fact that diagnostic procedures in psychiatry and clinical psychology still largely rely on the narratives of patients and questionnaires, supposedly subjective assessments by physicians and psychologists. It is envisioned that innovative (...) genetic and proteomic tools, imaging technologies, and objective laboratory tests for blood biomarkers will enable better diagnosis and treatment of mental diseases. We argue that emerging biotechnologies do not revolutionize mental health, despite their promise to do so. Instead, we observe a pluralization of research and treatment approaches in the domain of mental health. The second part of this editorial discusses the contributions to this special issue on emerging biotechnologies and mental health and outlines how they address some of the gaps in social studies of psychiatry and mental health in the twenty-first century.

Despite some principal similarities, there is no systematic comparison between the different types of synesthesia . This comprehensive review compares the three principal types of synesthesia and focuses on their phenomenological features and their relation to different etiological models. Implications of this comparison for the validity of the different etiological models are discussed.Comparison of the three forms of synesthesia show many more differences than similarities. This is in contrast to their representation in the literature, where they are discussed in many (...) respects as being virtually similar. Noteworthy is the much broader spectrum and intensity with the typical drug-induced synesthesias compared to genuine and acquired synesthesias. A major implication of the phenomenological comparison in regard to the etiological models is that genuine and acquired synesthesias point to morphological substrates, while drug-induced synesthesia appears to be based on functional changes of brain activity.

Dopamine is critically important in the neural manifestation of motivated behavior, and alterations in the human dopaminergic system have been implicated in the etiology of motivation-related psychiatric disorders, most prominently addiction. Patients with chronic addiction exhibit reduced dopamine D2 receptor (DRD2) availability in the striatum, and the DRD2 TaqIA (rs1800497) and C957T (rs6277) genetic polymorphisms have previously been linked to individual differences in striatal dopamine metabolism and clinical risk for alcohol and nicotine dependence. Here, we investigated the hypothesis that the (...) variants of these polymorphisms would show increased reward-related memory formation, which has previously been shown to jointly engage the mesolimbic dopaminergic system and the hippocampus, as a potential intermediate phenotype for addiction memory. To this end, we performed functional magnetic resonance imaging (fMRI) in 62 young, healthy individuals genotyped for DRD2 TaqIA and C957T variants. Participants performed an incentive delay task, followed by a recognition memory task 24 h later. We observed effects of both genotypes on the overall recognition performance with carriers of low-expressing variants, namely TaqIA A1 carriers and C957T C homozygotes, showing better performance than the other genotype groups. In addition to the better memory performance, C957T C homozygotes also exhibited a response bias for cues predicting monetary reward. At the neural level, the C957T polymorphism was associated with a genotype-related modulation of right hippocampal and striatal fMRI responses predictive of subsequent recognition confidence for reward-predicting items. Our results indicate that genetic variations associated with DRD2 expression affect explicit memory, specifically for rewarded stimuli. We suggest that the relatively better memory for rewarded stimuli in carriers of low-expressing DRD2 variants may reflect an intermediate phenotype of addiction memory. (shrink)

In this book, leading theorists present new contributions and reviews addressing longstanding challenges and ongoing progress in spacetime physics. In the anniversary year of Einstein's General Theory of Relativity, developed 100 years ago, this collection reflects the subsequent and continuing fruitful development of spacetime theories. The volume is published in honour of Carl Brans on the occasion of his 80th birthday. Carl H. Brans, who also contributes personally, is a creative and independent researcher and one of the founders of the (...) scalar-tensor theory, also known as Jordan-Brans-Dicke theory. In the present book, much space is devoted to scalar-tensor theories. Since the beginning of the 1990s, Brans has worked on new models of spacetime, collectively known as exotic smoothness, a field largely established by him. In this Festschrift, one finds an outstanding and unique collection of articles about exotic smoothness. Also featured are Bell's inequality and Mach's principle. Personal memories and historical aspects round off the collection. (shrink)

This article gives a brief introduction to the MacArthur Competence Assessment Tool-Treatment (MacCAT-T) and critically examines its theoretical presuppositions. On the basis of empirical, methodological and ethical critique it is emphasised that the cognitive bias that underlies the MacCAT-T assessment needs to be modified. On the one hand it has to be admitted that the operationalisation of competence in terms of value-free categories, e.g. rational decision abilities, guarantees objectivity to a great extent; but on the other hand it bears severe (...) problems. Firstly, the cognitive focus is in itself a normative convention in the process of anthropological value-attribution. Secondly, it misses the complexity of the decision process in real life. It is therefore suggested that values, emotions and other biographic and context specific aspects should be considered when interpreting the cognitive standards according to the MacArthur model. To fill the gap between cognitive and non-cognitive approaches the phenomenological theory of personal constructs is briefly introduced. In conclusion some main demands for further research to develop a multi-step model of competence assessment are outlined. (shrink)

This paper aims to give an insight into developments that contributed to the significance of the work of Jakob von Uexküll and stresses the importance of his occupation in Hamburg. A biographical survey pays tribute to the implication of the historical pretext and context. A scientific survey describes findings and ideas of Uexküll that proved important for the development of biology and the cognitive sciences. In addition, this paper sets out to reject the common notion that Uexküll’s concepts were ideas (...) of a purely theoretical and philosophical character. It confirms that in fact the central aims of his work were to sustain the empirical method in biology and to give biology a sound epistemological basis. Some examples show how historical and theoretical developments converged at Uexküll’s Institut für Umweltforschung in Hamburg and ignited a productive research activity. (shrink)

Goldstein and Gigerenzer (2002) [Models of ecological rationality: The recognition heuristic. Psychological Review, 109 (1), 75–90] found evidence for the use of the recognition heuristic. For example, if an individual recognizes only one of two cities, they tend to infer that the recognized city has a larger population. A prediction that follows is that of the less‐is‐more effect: Recognizing fewer cities leads, under certain conditions, to more accurate inferences than recognizing more cities. We extend the recognition heuristic to group decision‐making (...) by developing majority and lexicographic models of how recognition information is used by groups. We formally show when the less‐is‐more effect is predicted in groups and we present a study where three‐member groups performed the population comparison task. Several aspects of our data indicate that members who can use the recognition heuristic are, not in all but in most cases, more influential in the group decision process than members who cannot use the heuristic. We also observed the less‐is‐more effect and found that models assuming that members who can use the recognition heuristic are more influential better predict when the effect occurs. (shrink)

Despite a strong sensitization to the corruption problem and a large body of interdisciplinary research, scientists have only rarely investigated which motivational, volitional, emotional, and cognitive components make decision makers in companies act corruptly. Thus, we examined how their interrelation leads to corruption by proposing an action model. We tested the model using a business simulation game with students as participants. Results of the PLS structural equation modeling showed that both an attitude and subjective norm favoring corruption led to a (...) desire to act corruptly. Given high perceived behavioral control, this desire was transformed into an intention that finally resulted in corrupt action. Components related to general private and professional goals did not allow for any prediction. Based on these results, we discuss preventative measures and methods for combating intra- and inter-organizational corruption. (shrink)

Epistemic trust is crucial for science. This article aims to identify the kinds of assumptions that are involved in epistemic trust as it is required for the successful operation of science as a collective epistemic enterprise. The relevant kind of reliance should involve working from the assumption that the epistemic endeavors of others are appropriately geared towards the truth, but the exact content of this assumption is more difficult to analyze than it might appear. The root of the problem is (...) that methodological decisions in science typically involve a complex trade-off between the reliability of positive results, the reliability of negative results, and the investigation's power. Which balance between these is the ‘correct’ one can only be determined in light of an evaluation of the consequences of all the different possible outcomes of the inquiry. What it means for the investigation to be ‘appropriately geared towards the truth’ thus depends on certain value judgments. I conclude that in the optimal case, trusting someone in her capacity as an information provider also involves a reliance on her having the right attitude towards the possible consequences of her epistemic work. 1 Introduction2 Epistemic Reliance within the Sciences3 Methodological Conventionalism4 Trust in Science5 Conclusions.

When interests and preferences of researchers or their sponsors cause bias in experimental design, data interpretation or dissemination of research results, we normally think of it as an epistemic shortcoming. But as a result of the debate on science and values, the idea that all extra-scientific influences on research could be singled out and separated from pure science is now widely believed to be an illusion. I argue that nonetheless, there are cases in which research is rightfully regarded as epistemologically (...) deficient due to the influence of preferences on its outcomes. I present examples from biomedical research and offer an analysis in terms of social epistemology. (shrink)

In recent years, a variety of philosophers have argued that the fundamental bearers of representational properties like truth are concrete particulars produced by cognitive agents—representational vehicles (“RVs”), as I will call them. This view apparently conflicts with other judgments that are part of our common sense understanding of truth. For instance, it is plausible that there are truths about the Milky Way that have and never will never be articulated by anyone. Whatever these truths are, it looks like they cannot (...) be RVs, because an RV is articulated just in case it exists. In this paper, I argue that it is consistent to hold that the fundamental truth-bearers are representational vehicles, while also acknowledging the existence of unarticulated truths. I argue that truth is a property that derivatively holds of kinds of RVs, that these provide the basis for our judgments that there are unarticulated truths, and I defend the view against putative counter-examples.

The notion of ecological rationality implies that the accuracy of a decision strategy depends on features of the information environment in which it is tested. We demonstrate that the performance of a group may be strongly affected by the decision strategies used by its individual members and specify how this effect is moderated by environmental features. Specifically, in a set of simulation studies, we systematically compared four decision strategies used by the individual group members: two linear, compensatory decision strategies and (...) two simple, noncompensatory heuristics. Individual decisions were aggregated by using a majority rule. To assess the ecological rationality of the strategies, we varied (a) the distribution of cue validities, (b) the quantity, and (c) the quality of shared information. Group performance strongly depended on the distribution of cue validities. When validities were linearly distributed, groups using a compensatory strategy achieved the highest accuracy. Conversely, when cue validities followed a J-shaped distribution, groups using a simple lexicographic heuristic performed best. While these effects were robust across different quantities of shared information, the quality of shared information exerted stronger effects on group performance. Consequences for prescriptive theories on group decision making are discussed. (shrink)

This chapter provides an analysis of the long process of introducing an electronic identity for online authentication in Germany. This process is described as a multi-facet innovation, involving actors from different policy fields shifting over time. The eID process started in the late ‘90s in the context of eGovernment and eCommerce with the legislation on e-signatures, which were supposed to allow for online authentication of citizens. When after 5 years it was recognized that this was not the case, a new (...) digital ID card, which had meanwhile been announced, was chosen as token for the eID. This process was dominated by the concerns for visual inspection and border control, including the storage of digital fingerprints. Under the leadership of the Ministry of the Interior (BMI) and technical guidance of the Federal Agency for Information Security (BSI), technical specifications have to a large extent been adopted from the electronic passport, which had been smoothly introduced 2 years before. However, in the legislative process some concern regarding digital fingerprints on the eID card was raised and led to an opt-in solution. In 2009, a bill on the new ID card was passed which regulates the eID function for online authentication as well. This is characterized as a radical innovation by introducing a double-sided, mutual authentication of the citizen and the service provider and implementing the principle of proportionality regarding the access of service providers to data on the chip. At the time of writing, field tests are conducted. Roll-out of the new eID card is to start in November 2010. Therefore no figures about adoption can be provided here. (shrink)
