The Hox genes play a role in anteroposterior axis specification of bilaterian animals that has been conserved for more than 600 million years. However, some of these genes have occasionally changed their roles in evolution. For example, the insect gene fushi tarazu (ftz), although localised in the Hox cluster, no longer acts as a Hox gene, but is involved in segmentation and nervous system development. Recent data of Mouchel‐Vielh et al.,1 and Hughes and Kaufman2 on ftz homologues in a crustacean (...) and a myriapod, respectively, shed new light onto the evolution of this gene.

Today's complex and decentralized organization gives rise to organizational needs for both loyalty and institutionalized whistle blowing. However, ethicists see a contradiction between both needs. This paper argues there is no such contradiction. It shows why earlier attempts to go beyond the dilemma are not satisfying. The solution proposed in this paper starts from an organizational perspective instead of an individual one. It does so by reframing the concept of loyalty into rational loyalty. This means that the object of loyalty (...) is not the physicality of an organization, but its corpus of explicit mission statement, goals, value statement and code of conduct. An implication is that organizations are – as their side of the duty of loyalty – obliged to institutionalize whistle blowing. (shrink)

In this article some of the presuppositions that underly the current ideas about decision making capacity, autonomy and independence are critically examined. The focus is on chronic disorders, especially on chronic physical disorders. First, it is argued that the concepts of decision making competence and autonomy, as they are usually applied to the problem of legal (in)competence in the mentally ill, need to be modified and adapted to the situation of the chronically (physically) ill. Second, it is argued that autonomy (...) and dependence must not be considered as two mutually exclusive categories. It is suggested that decision making may take on the form of a more or less conscious decision not to be involved in making all kinds of explicit and deliberate decisions. Elaborating on Agich's distinction between ideal and actual autonomy, the concept of Socratic autonomy is introduced. (shrink)

In his concept of an anthropological physiology, F.J.J. Buytendijk has tried to lay down the theoretical and scientific foundations for an anthropologically-oriented medicine. The aim of anthropological physiology is to demonstrate, empirically, what being specifically human is in the most elementary physiological functions. This article contains a sketch of Buytendijk''s life and work, an overview of his philosophical-anthropological presuppositions, an outline of his idea of an anthropological physiology and medicine, and a discussion of some episternological and methodological problems. It is (...) demonstrated that Buytendijk''s design of an anthropological physiology is fragmentary and programmatic and that his methodology offers few points of contact for specific anthropological experimental research.Notwithstanding, it is argued that Buytendijk''s description of the subjective, animated body forms a pre-eminent point of reference for all research in physiology and psychology in which the specific human aspect is not ignored beforehand.

This paper offers a speculative elaboration on downward workplace mobbing – the intentional and repeated inflictions of physical or psychological harm by superiors on subordinates within an organization. The authors cite research showing that workplace mobbing is not a marginal fact in today's organizations and that downward workplace mobbing is the most prevalent form. The authors also show that causes of and facilitating circumstances for downward workplace mobbing, mentioned by previous research, match current organizational shifts taking place within a context (...) of globalisation. This paper argues that it is not the organizational shifts themselves which are to "blame", but an inadequate transformation of leadership and power in reaction to those shifts. Using Foucault's power-knowledge-rules of right triad, the authors offer an explanation for downward workplace mobbing beyond the organizational changes themselves. More precisely, as the organizational changes can be characterized by a new power/knowledge bond calling forth new rules of right, downward workplace mobbing could be seen as manifestations of power outside of the delineations drawn by these new rules of right. In other words, downward workplace mobbing is pathology of current organizational shifts, resulting from not acting out the full ethical potential of the discourse of excellence, adventure, creativity and responsibility, which characterizes these shifts.

As thousands of healthy research participants are being included in small and large imaging studies, it is essential that dilemmas raised by the detection of incidental findings are adequately handled. Current ethical guidance indicates that pathways for dealing with incidental findings should be in place, but does not specify what such pathways should look like. Building on an interview study of researchers’ practices and perspectives, we identified key considerations for the set-up of pathways for the detection, management and communication of (...) incidental findings in imaging research. We conducted an interview study with a purposive sample of researchers at research facilities across the Netherlands. Based on a qualitative analysis of these interviews and on existing guidelines found in the literature, we developed a prototype ethical framework, which was critically assessed and fine-tuned during a two-day international expert meeting with bioethicists and representatives from large population-based imaging studies from the United Kingdom, Germany, Sweden and Belgium. Practices and policies for the handling of incidental findings vary strongly across the Netherlands, ranging from no review of research scans and limited feedback to research participants, to routine review of scans and the arrangement of clinical follow-up. Respondents felt that researchers do not have a duty to actively look for incidental findings, but they do have a duty to act on findings, when detected. The principle of reciprocity featured prominently in our interviews and expert meeting. We present an ethical framework that may guide researchers and research ethics committees in the design and/or evaluation of appropriate pathways for the handling of incidental findings in imaging studies. The framework consists of seven steps: anticipation of findings, information provision and informed consent, scan acquisition, review of scans, consultation on detected abnormalities, communication of the finding, and further clinical management and follow-up of the research participant. Each of these steps represents a key decision to be made by researchers, which should be justified not only with reference to costs and/or logistical considerations, but also with reference to researchers’ moral obligations and the principle of reciprocity.

There have been few empirical studies into what non-medical factors influence physicians and nurses when deciding about admission and discharge of ICU patients. Information about the attitudes of healthcare professionals about this process can be used to improve decision-making about resource allocation in intensive care. To provide insight into ethical problems that influence the ICU admission and discharge process, we aimed to identify and explore ethical dilemmas healthcare professionals are faced with.

In this article a case is made for the importance of a previously overlooked phenomenon, physical empathy orcompathy,defined as the physical manifestation of caregiver distress that occurs in the presence of a patient in physical pain or distress. According to the similarity of a caregiver's response to the original symptoms, there can be four types of compathetic response: identical, initiated, transferred, and converted. Controlling for the compathetic response may involve narrowing one's focus and/or changing caregiver attitudes. Finally, we argue that (...) while the compathetic response may be beneficial to the caregiving relationship, enabling the provision of appropriate and adequate humane treatment and care, the caregiver must at times shield against the compathetic response in order to provide care.

Speakers often use gesture to demonstrate how to perform actions—for example, they might show how to open the top of a jar by making a twisting motion above the jar. Yet it is unclear whether listeners learn as much from seeing such gestures as they learn from seeing actions that physically change the position of objects (i.e., actually opening the jar). Here, we examined participants' implicit and explicit understanding about a series of movements that demonstrated how to move a set (...) of objects. The movements were either shown with actions that physically relocated each object or with gestures that represented the relocation without touching the objects. Further, the end location that was indicated for each object covaried with whether the object was grasped with one or two hands. We found that memory for the end location of each object was better after seeing the physical relocation of the objects, that is, after seeing action, than after seeing gesture, regardless of whether speech was absent (Experiment 1) or present (Experiment 2). However, gesture and action built similar implicit understanding of how a particular handgrasp corresponded with a particular end location. Although gestures miss the benefit of showing the end state of objects that have been acted upon, the data show that gestures are as good as action in building knowledge of how to perform an action.

This interview study investigates the short- and long-term implications of incidental findings detected through brain imaging on research participants’ lives and their surroundings. For this study, nine participants of the Rotterdam Scan Study with an incidental finding were approached and interviewed. When examining research participants’ narratives on the impact of the disclosure of incidental findings, the authors identified five sets of tensions with regard to motivations for and expectations of research participation, preferences regarding disclosure, short- and long-term impacts and impacts (...) on self and others. The paper shows: that the impact of incidental findings may be greater than participants at first let on; incidental findings can have significant effects on participants’ social environment; and participants may not feel prepared for disclosure even if incidental findings have been discussed during the informed consent process. The authors call for investigators to be aware of research participants’ experiences and these short- and long-term impacts when designing suitable courses of action for the detection and management of incidental findings in research settings.

The spiders Cupiennius salei and Achaearanea tepidariorum are firmly established laboratory models that have already contributed greatly to answering evolutionary developmental questions. Here we appraise why these animals are such useful models from phylogeny, natural history and embryogenesis to the tools available for their manipulation. We then review recent studies of axis formation, segmentation, appendage development and neurogenesis in these spiders and how this has contributed to understanding the evolution of these processes. Furthermore, we discuss the potential of comparisons of (...) silk production between Cupiennius and Achaearanea to investigate the origins and diversification of this evolutionary innovation. We suggest that further comparisons between these two spiders and other chelicerates will prove useful for understanding the evolution of development in metazoans.

BackgroundLiterature shows that middle-aged and older adults sometimes experience a wish to die. Reasons for these wishes may be complex and involve multiple factors. One important question is to what extent people with a wish to die have medically classifiable conditions. Aim(1) Estimate the prevalence of a current wish to die among middle-aged and older adults in The Netherlands; (2) explore which factors within domains of vulnerability (physical, cognitive, social and psychological) are associated with a current wish to die; (3) (...) assess how many middle-aged and older adults with a current wish to die do not have a medically classifiable condition and/or an accumulation of age-related health problems.MethodsData of 2015/16 from the Longitudinal Aging Study Amsterdam were used for this cross-sectional study (1563 Dutch middle-aged and older adults aged between 57 and 99 years), obtained through structured medical interviews and self-reported questionnaires. Three experienced physicians assessed whether the participants with a current wish to die could be classified as having a medically classifiable condition and/or an accumulation of age-related health problems.ResultsN = 62 participants (4.0%) had a current wish to die. Having a current wish to die was associated with multiple characteristics across four domains of vulnerability, among which: self-perceived health, problems with memory, self-perceived quality of life and meaningfulness of life. Fifty-four participants with a current wish to die were assessed with having a medically classifiable condition, of which one was also assessed with having an accumulation of age-related health problems. Six people were assessed to have neither, and for two people it was unclear.ConclusionA small minority of middle-aged and older adults in the Netherlands have a current wish to die. Most of them can be classified with a medical condition and one person with an accumulation of age-related health problems. Furthermore, the findings show that having a current wish to die is multi-faceted. There is still a need for more knowledge, such as insight in to what extent suffering stemming from the medical classifiable disease contributes to the development of the wish to die. (shrink)

Mercier and Sperber (M&S) sketch a bleak picture of logical reasoning in classic, nonargumentative tasks. I argue that recent processing data indicate that despite people's poor performance they at least seek to adhere to traditional logical norms in these tasks. This implies that classic reasoning tasks are less artificialthan M&S's framework suggests.

In this paper I respond to Wim van der Steen''s arguments against the supposed current overemphasis on norms ofcoherence andinterdisciplinary integration in biology. On the normative level, I argue that these aremiddle-range norms which, although they may be misapplied in short-term attempts to solve (temporarily?) intractable problems, play a guiding role in the longer-term treatment of biological problems. This stance is supported by a case study of apartial success story, the development of the one gene — one enzyme hypothesis. As (...) that case shows, thegoal of coherent interdisciplinary integration not only provides guidance for research, but also provides the standard for recognizingfailed integrations of the sort that van der Steen criticizes.

Prof. W.A. Dreyer played an important role in the continuous reformation of the Nederduitsch Hervormde Kerk van Afrika (NHKA). This contribution to his Festschrift is not about him. He would not want that. It is about the church and how his understanding of reformed ecclesiology became the basis on which the transformation from ‘ Volkskerk ’ to missional church took place. According to himself, that was his calling and his life’s work. The importance of his contribution cannot be understood without (...) the historical background in which it played out. Neither is it possible to envisage what really happened without acknowledging the theologians who played an important part in his life. This article therefore starts with a short overview of the history of the NHKA. It then proceeds with an overview of how important theologians in the NHKA influenced his ecclesiology. It concludes with three specific contributions that Prof. W.A. Dreyer made which makes him a key role player which led the NHKA on the way of Ecclesia reformata semper reformanda. Contribution: Prof. W.A. Dreyer became an important church leader in the Netherdutch Reformed Church. His leadership resulted in important changes in the church and especially in the ecclesiology of the church. This article, which is part of his Festschrift, gives an overview of his theological contribution through the lens of semper reformanda. By doing so, it indicates how important is the role of church leaders. All the research is based on his scholarly work. (shrink)

This study described the relationships between academic class and student moral sensitivity and reasoning and between curriculum design components for ethics education and student moral sensitivity and reasoning. The data were collected from freshman (n = 506) and senior students (n = 440) in eight baccalaureate nursing programs in South Korea by survey; the survey consisted of the Korean Moral Sensitivity Questionnaire and the Korean Defining Issues Test. The results showed that moral sensitivity scores in patient-oriented care and conflict were (...) higher in senior students than in freshman students. Furthermore, more hours of ethics content were associated with higher principled thinking scores of senior students. Nursing education in South Korea may have an impact on developing student moral sensitivity. Planned ethics content in nursing curricula is necessary to improve moral sensitivity and moral reasoning of students. (shrink)

This article deals with the question of how self-organization in living organisms is realized. Self-organization may be observed in open systems that are out of equilibrium. Many disequilibria-conversion phenomena exist where free energy conversion occurs by spontaneously formed engines. However, how is self-organization realized in living entities? Living cells turn out to be self-organizing disequilibria-converting systems of a special kind. Disequilibrium conversion is realized in a typical way, through employing information specifying protein complexes acting as nano engines. The genetic code (...) enables processing of information—derived from coding DNA—to produce these molecular machines. Hence, information is at the core of living systems. Two promising approaches to explaining living cells containing sequences carrying information are mentioned. Also discussed is the question of whether a second concept of self-organization—namely, the Kantian concept—applies. (shrink)

Socially Responsible Investment (SRI) has grown considerably over the past three decades. One form of SRI, engagement-SRI, is today by far the most practiced form of SRI (in assets managed) and has the potential to mainstream SRI even further. However, lack of formalized engagement procedures and evaluation tools leave the engagement practice too opaque for such a mainstreaming. This article can be considered as a first step in the development of a standard for the engagement practice. By developing an engagement (...) heuristic, this article offers a more transparent engagement dialog. Drawing on Stevenson's and Austin's speech-act theories, this article develops a classification of management's responses to the signaling of allegations and controversies on two dimensions: a factual dimension concerning (dis)agreements on factual claims and an attitudinal dimension concerning (dis)agreements on responsibilities, values, and norms. On the basis of the distinctions this article develops, the authors provide for a synoptic table and offer a next-step heuristic for the engagement process that started with signaling a concern to management. The article uses an engagement logic that, while keeping the exit option for the investor open, allows management to address signaled concerns without having to let down or to opt out at the first setback in the dialog process between investor and investee corporation.

An arms race for an artificial general intelligence would be detrimental for and even pose an existential threat to humanity if it results in an unfriendly AGI. In this paper, an all-pay contest model is developed to derive implications for public policy to avoid such an outcome. It is established that, in a winner-takes-all race, where players must invest in R&D, only the most competitive teams will participate. Thus, given the difficulty of AGI, the number of competing teams is unlikely (...) ever to be very large. It is also established that the intention of teams competing in an AGI race, as well as the possibility of an intermediate outcome, is important. The possibility of an intermediate prize will raise the probability of finding the dominant AGI application and, hence, will make public control more urgent. It is recommended that the danger of an unfriendly AGI can be reduced by taxing AI and using public procurement. This would reduce the pay-off of contestants, raise the amount of R&D needed to compete, and coordinate and incentivize co-operation. This will help to alleviate the control and political problems in AI. Future research is needed to elaborate the design of systems of public procurement of AI innovation and for appropriately adjusting the legal frameworks underpinning high-tech innovation, in particular dealing with patenting by AI.
