Peer review is a widely accepted instrument for raising the quality of science. Peer review limits the enormous unstructured influx of information and the sheer amount of dubious data, which in its absence would plunge science into chaos. In particular, peer review offers the benefit of eliminating papers that suffer from poor craftsmanship or methodological shortcomings, especially in the experimental sciences. However, we believe that peer review is not always appropriate for the evaluation of controversial hypothetical science. We argue that (...) the process of peer review can be prone to bias towards ideas that affirm the prior convictions of reviewers and against innovation and radical new ideas. Innovative hypotheses are thus highly vulnerable to being “filtered out” or made to accord with conventional wisdom by the peer review process. Consequently, having introduced peer review, the Elsevier journal Medical Hypotheses may be unable to continue its tradition as a radical journal allowing discussion of improbable or unconventional ideas. Hence we conclude by asking the publisher to consider re-introducing the system of editorial review to Medical Hypotheses. (shrink)

The parameters governing our behavior are in constant flux. Accurately capturing these dynamics in cognitive models poses a challenge to modelers. Here, we demonstrate a mapping of ACT-R's declarative memory onto the linear ballistic accumulator (LBA), a mathematical model describing a competition between evidence accumulation processes. We show that this mapping provides a method for inferring individual ACT-R parameters without requiring the modeler to build and fit an entire ACT-R model. Existing parameter estimation methods for the LBA can be used, (...) instead of the computationally expensive parameter sweeps that are traditionally done. We conduct a parameter recovery study to confirm that the LBA can recover ACT-R parameters from simulated data. Then, as a proof of concept, we use the LBA to estimate ACT-R parameters from an empirical dataset. The resulting parameter estimates provide a cognitively meaningful explanation for observed differences in behavior over time and between individuals. In addition, we find that the mapping between ACT-R and LBA lends a more concrete interpretation to ACT-R's latency factor parameter, namely as a measure of response caution. This work contributes to a growing movement towards integrating formal modeling approaches in cognitive science. (shrink)

In the Netherlands fertility doctors increasingly formulate protocols, which oblige patients to quit their unhealthy lifestyle before they are admitted to IVF procedures. We argue that moral arguments could justify parenting protocols that concern all future parents. In the first part we argue that want‐to‐be parents have moral responsibilities towards their future children to prevent them from harm by diminishing or eliminating risk factors before as well as during the pregnancy. This is because of the future children's potential to become (...) of a certain type, more specifically: a person that will be the want‐to‐be parents' child. Want‐to‐be parents intend to become pregnant and therefore have an additional moral reason to diminish the risks. Also, people who become pregnant unintentionally have the responsibility to prevent their children from harm, unless they become pregnant due to contraception failure. All people not wanting to become pregnant should use contraception methods carefully.In the second part of this paper we translate the want‐to‐be parents' responsibilities into practice. We distinguish four determinants of risk factors: modifiability, chance, severity and effort. We examine some evidence‐based risk factors based on these variables and deduce levels of responsibility.In conclusion, formulating informal requirements for want‐to‐be parents is morally required and therefore also for want‐to‐be parents in need of medical assistance. The protocols developed by fertility doctors in the Netherlands could be seen as the precursor for a general, informal Parenting Protocol that could be developed on the basis of an extended and thoroughly debated risk‐responsibility analysis.

Fraud is a pervasive and challenging problem that costs society large amounts of money. By no means all fraud is committed by ‘professional criminals’: much is done by ordinary people who indulge in small-scale opportunistic deception. In this paper, we set out to investigate when people behave dishonestly, for example by committing fraud, in an online context. We conducted three studies to investigate how the rejection of one’s efforts, operationalized in different ways, affected the amount of cheating and information falsification. (...) Study 1 demonstrated that people behave more dishonestly when rejected. Studies 2 and 3 were conducted in order to disentangle the confounding factors of the nature of the rejection and the financial rewards that are usually associated with dishonest behavior. It was demonstrated that rejection in general, rather than the nature of a rejection, caused people to behave more dishonestly. When a rejection was based on subjective grounds, dishonest behavior increased with approximately 10%, but this difference was not statistically significant. We subsequently measured whether dishonesty was driven by the financial loss associated with rejection, or emotional factors such as a desire for revenge. We found that rejected participants were just as dishonest when their cheating did not led to financial gain. However, they felt stronger emotions when there was no money involved. This seems to suggest that upon rejection, emotional involvement, especially a reduction in happiness, drives dishonest behavior more strongly than a rational cost-benefit analysis. These results indicate that rejection causes people to behave more dishonestly, specifically in online settings. Firms wishing to deter customers and employees from committing fraud may therefore benefit from transparency and clear policy guidelines, discouraging people to submit claims that are likely to be rejected.

Health care professionals often face moral dilemmas. Not dealing constructively with moral dilemmas can cause moral distress and can negatively affect the quality of care. Little research has been documented with methodologies meant to support professionals in care for the homeless in dealing with their dilemmas. Moral case deliberation is a method for systematic reflection on moral dilemmas and is increasingly being used as ethics support for professionals in various health-care domains. This study deals with the question: What is the (...) contribution of MCD in helping professionals in an institution for care for the homeless to deal with their moral dilemmas? A mixed-methods responsive evaluation design was used to answer the research question. Five teams of professionals from a Dutch care institution for the homeless participated in MCD three times. Professionals in care for the homeless value MCD positively. They report that MCD helped them to identify the moral dilemma/question, and that they learned from other people’s perspectives while reflecting and deliberating on the values at stake in the dilemma or moral question. They became aware of the moral dimension of moral dilemmas, of related norms and values, of other perspectives, and learned to formulate a moral standpoint. Some experienced the influence of MCD in the way they dealt with moral dilemmas in daily practice. Half of the professionals expect MCD will influence the way they deal with moral dilemmas in the future. Most of them were in favour of further implementation of MCD in their organization. (shrink)

AimVisual functions of the dorsal stream are considered vulnerable in children with early brain damage. Considering the recognition of objects in suboptimal representations a dorsal stream dysfunction, we examined whether children with early brain damage and impaired object recognition had either general or selective dorsal stream dysfunctions.MethodIn a group of children with early brain damage we evaluated the dorsal stream functioning. To determine whether these patients had an increased risk of a dorsal stream dysfunction we compared the percentage of patients (...) with impaired object recognition, assessed with the L94, with the estimated base rate. Then we evaluated the performance levels on motion perception, visual attention and visuomotor tasks in patients with and without object recognition abnormalities. A general dorsal stream dysfunction was considered present if a patient showed at least one abnormally low score in two out of three additional dorsal stream functions.ResultsSix of the eighteen patients with object recognition problems scored abnormally low on at least two additional dorsal stream functions. This was significantly higher than the base rate. The difference of 24.1% between the patients with and without object recognition problems was not significant. Of the patients with object recognition problems 72.2% had at least 1 dorsal weakness, whereas this was only the case in 27.3% of patients without object recognition problems. Compared to patients with normal object recognition, patients with object recognition problems scored significantly more abnormally low on motion perception and visual attention but did not differ on visuomotor skills.ConclusionChildren with object recognition problems seem at risk for other dorsal stream dysfunctions, but dysfunctions might be rather specific than general. Multiple functions/aspects should be evaluated in neuropsychological assessment of children at risk. (shrink)

In the reported, experiment participants hit a ball to aim at the vertex of a Müller–Lyer configuration. This configuration either remained stable, changed its shaft length or the orientation of the tails during movement execution. A significant illusion bias was observed in all perturbation conditions, but not in the stationary condition. The illusion bias emerged for perturbations shortly after movement onset and for perturbations during execution, the latter of which allowed only a minimum of time for making adjustments . These (...) findings indicate that allocentric information is exploited for online control when people make rapid adjustments in response to a sudden change in the environment and not when people guide their limb movements to interact with a stable environment.

One of the goals of computerized tutoring systems is to optimize the learning of facts. Over a hundred years of declarative memory research have identified two robust effects that can improve such systems: the spacing and the testing effect. By making optimal use of both and adjusting the system to the individual learner using cognitive models based on declarative memory theories, such systems consistently outperform traditional methods (Van Rijn, Van Maanen, & Van Woudenberg, 2009). This adjustment process is driven by (...) a continuously updated estimate of the rate of forgetting for each item and learner on the basis of the learner's accuracy and response time. In this study, we investigated to what extent these estimates of individual rates of forgetting are stable over time and across different materials. We demonstrate that they are stable over time but not across materials. Even though most theories of human declarative memory assume a single underlying rate of forgetting, we show that, in practice, it makes sense to assume different materials are forgotten at different rates. If a computerized, adaptive fact‐learning system allowed different rates of forgetting for different materials, it could adapt to individual learners more readily. (shrink)

Although emotions play a crucial role in understanding and encouraging sustainable behavior and decision-making, many open questions currently remain unanswered. In this review, we advance three broad areas of particular theoretical and applied importance that affective science and emotion researchers could benefit from engaging with: (1) “ sustainable emotions” or empirically testing the possibility of positive reinforcing feedback loops between anticipatory and experienced emotions following the adoption of sustainable behaviors, (2) “ non- Western emotions” or exploring the extent to which (...) people's understanding and experience of climate-relevant emotions differs across non-WEIRD populations, and (3) “ impactful emotions” or the need to carefully differentiate the conceptual and empirical role of emotions in encouraging the adoption of low-impact (e.g., recycling) versus high-impact (e.g., flying less) environmental behaviors.

We investigated, by means of the Reverse Correlation Task, visual representations of the culturally dominating group of local people held by sojourners as a function of their degree of cross-cultural adaptation. In three studies, using three different methods with three independent samples of sojourners and seven independent samples of Portuguese and US-American raters, we gathered clear evidence that poor adaptation goes along with more negative representations of locals. This indicates that sojourner adaptation is reflected, at a social-cognitive level, in the (...) valence of outgroup representations. (shrink)

Interactive technology assessment (iTA) provides an answer to the ethical problem of normative bias in evaluation research. This normative bias develops when relevant perspectives on the evaluand (the thing being evaluated) are neglected. In iTA this bias is overcome by incorporating different perspectives into the assessment. As a consequence, justification of decisions based on the assessment is provided by stakeholders having achieved agreement. In this article, agreement is identified with wide reflective equilibrium to show that it indeed has the potential (...) of justifying decisions. We work out several conditions for this agreement to be achievable and just. (shrink)

Les décisions politiques sur les risques environnementaux complexes font fréquemment intervenir des éléments scientifiques contestés. Il n’y a généralement pas de « faits » qui conduisent à une politique correcte unique. Les éléments de preuve qui sont intégrés dans les avis scientifiques destinés à une décision politique nécessitent une évaluation de leur qualité. En 2003, l’Agence néerlandaise d’évaluation environnementale a adopté une méthode standardisée, désignée sous le nom de « guide », dans le cadre de laquelle les principaux aspects de (...) la production et de l’utilisation des connaissances sont présentés grâce à une liste de contrôle visant à l’évaluation et à la communication des incertitudes. Dans cet article, nous présentons des résultats de l’application de ce guide à la controverse sur les risques des particules en suspension. La délibération active sur l’incertitude dans un contexte d’expertise entraîne un processus d’apprentissage commun entre les experts et les décideurs politiques, ce qui conduit à une meilleure prise de conscience du phénomène d’incertitude et de ses implications politiques.Policy decisions on complex environmental risks often involve disputed science. Typically, there are no “ facts” to support a single unequivocally correct policy. The evidence provided in scientific studies for policy-making decisions requires high-quality assessment. In 2003, the Netherlands Environmental Assessment Agency adopted a standardized method, referred to as “guidelines”, whereby key quality aspects of knowledge production and use are presented in the form of a checklist for uncertainty assessments and communication. In this article, we present the outcomes of applying the guidelines in controversies on the risks of ambient particulate matter. In the policy–advisory context, active deliberation on uncertainty produces a common learning process for advisors and policy makers, which leads to a deeper understanding and increased awareness of the phenomenon of uncertainty and its policy implications.

Background Studies describing physicians’ experiences with sedation at the end of life are indispensible for informed palliative care practice, but they are scarce. We describe the accounts of physicians from the USA and the Netherlands, two countries with different regulations on end-of-life decisions regarding their use of sedation.Methods Qualitative face-to-face interviews were held in 2007–2008 with 36 physicians , including primary care physicians and specialists. We applied purposive sampling and conducted constant comparative analyses.Results In both countries, the use of sedation (...) was described in diverse terms, especially in the USA, and was often experienced as emotionally challenging. Respondents stated different and sometimes multiple intentions for their use of sedation. Besides alleviating severe suffering, most Dutch respondents justified its use by stating that it does not hasten death, while most American respondents indicated that it might hasten death but that this was justifiable as long as that was not their primary intention. While many Dutch respondents indicated that they initiated open discussions about sedation proactively to inform patients about their options and to allow planning, the accounts of American respondents showed fewer and less-open discussions, mostly late in the dying process and with the patient's relatives.Conclusions The justification for sedation and the openness with which it is discussed were found to differ in the accounts of respondents from the USA and the Netherlands. Further clarification of practices and research into the effect and effectiveness of the use of sedation is recommended to enhance informed reflection and policy making. (shrink)

The way students perceive a learning climate (e.g. controlling or stimulating) is significantly influenced by feedback and assessment. However, at present much is unclear about the relation between feedback and motivational state. More specifically, the interplay with student characteristics is unclear. Since there is a strong increase of group work, the central research question is what are the effects of positive, neutral or negative feedback presented to collaborating teams of students, on students? intrinsic motivation, performance and on group processes? One (...) hundred thirty?eight higher education students participated in this study. There were no significant differences in performance across conditions. Multi?level analysis enabled a detailed comparison between groups and individual members of groups. Amongst others, it was found that feelings of competence facilitate the effect of positive feedback at the group level, which suggests that positive feedback boosts interest especially in groups of highly competent students.

Regret and disappointment have in common the fact that they are experienced when the outcome of a decision is unfavourable: They both concern “what might have been”, had things been different. However, some regret and disappointment theorists regard the differences between these emotions as important, arguing that they differ with respect to the conditions under which they are felt, and how they affect decision making. The goal of the present research was to examine whether and how these emotions also differ (...) with respect to the way in which they are experienced. Participants were asked torecall aninstance of intense regret or disappointment andto indicate what they felt, thought, felt like doing, did, and were motivated to do during this experience (cf. Roseman, Wiest, & Swartz, 1994). Significant differences between regret and disappointment were found in every category. These differences were most pronounced for “action tendencies” (what participants felt like doing) and “emotivations” (what they were motivated to do). These results suggest that the two emotions have differential implications for future behaviour. (shrink)

Sonja Plischke’s Die Seleukiden und Iran is an attempt to study Seleucid empire building in Iran. In view of the fact that indigenous written sources from Iran are practically absent, Plischke decided to include Babylonia in this work, since the written cuneiform evidence from that region is fairly abundant. She detects some general tendencies—such as religious policy and the general wish to connect the different parts of the empire—supported by a personal conception of Seleucid kingship, beside more specific treatment of (...) different regions. In my view, the Seleucids probably did not pay sufficient attention to the East, so that their control weakened. I take the opportunity to discuss the Babylonian sources, correct errors in Plischke’s use of them, and adduce some new publications. (shrink)

ABSTRACT:Profit maximizers have reasons to agree with stakeholder theorists that managers may need to consider different values simultaneously in decision making. However, it remains unclear how maximizing a single value can be reconciled with simultaneously considering different values. A solution can neither be found in substantive normative philosophical theories, nor in postulating the maximization of profit. Managers make sense of the values in a situation by means of the many thick value concepts of ordinary language. Thick evaluation involves the simultaneous (...) consideration of different values: making sense of a value always involves knowing how to engage with it given the other values in the situation. This also goes for profit: maximization is only one way of engaging with the value of profit, and grasping whether maximization is appropriate involves considering other values. We discuss some consequences of our approach for stakeholder theorists and profit maximizers. (shrink)

A crisis looms over the scientific enterprise. Not a day passes without news of retractions, failed replications, fraudulent peer reviews, or misinformed science-based policies. The social implications are enormous, yet this crisis has remained largely uncharted-until now. In Science on the Verge, luminaries in the field of post-normal science and scientific governance focus attention on worrying fault-lines in the use of science for policymaking, and the dramatic crisis within science itself. This provocative new volume in The Rightful Place of Science (...) also explores the concepts that need to be unlearned, and the skills that must be relearned and enhanced, if we are to restore the legitimacy and integrity of science.

This article aims to achieve two goals: to show that probability is not the only way of dealing with uncertainty ; and to provide evidence that logic-based methods can well support reasoning with uncertainty. For the latter claim, two paradigmatic examples are presented: logic programming with Kleene semantics for modelling reasoning from information in a discourse, to an interpretation of the state of affairs of the intended model, and a neural-symbolic implementation of input/output logic for dealing with uncertainty in dynamic (...) normative contexts.
