Moral or ethical questions are vital because they affect our daily lives: what is the best choice we can make, the best action to take in a given situation, and ultimately, the best way to live our lives? Health ethics has contributed to moving ethics toward a more experience-based and user-oriented theoretical and methodological stance but remains in our practice an incomplete lever for human development and flourishing. This context led us to envision and develop the stance (...) of a “living ethics”, described in this inaugural collective and programmatic paper as an effort to consolidate creative collaboration between a wide array of stakeholders. We engaged in a participatory discussion and collective writing process known as instrumentalist concept analysis. This process included initial local consultations, an exploratory literature review, the constitution of a working group of 21 co-authors, and 8 workshops supporting a collaborative thinking and writing process. First, a living ethics designates a stance attentive to human experience and the role played by morality in human existence. Second, a living ethics represents an ongoing effort to interrogate and scrutinize our moral experiences to facilitate adaptation of people and contexts. It promotes the active and inclusive engagement of both individuals and communities in envisioning and enacting scenarios which correspond to their flourishing as authentic ethical agents. Living ethics encourages meaningful participation of stakeholders because moral questions touch deeply upon who we are and who we want to be. We explain various aspects of a living ethics stance, including its theoretical, methodological, and practical implications as well as some barriers to its enactment based on the reflections resulting from the collaborative thinking and writing process.

I ask whether the Recollection argument commits Socrates to the view that our only source of knowledge of the Forms is sense perception. I argue that Socrates does not confine our presently available sources of knowledge to empirically based recollection, but that he does think that we can't begin to move towards a philosophical understanding of the Forms except as a result of puzzles prompted by the shortfall of particulars in relation to the Forms, and hence that our awareness of (...) the Forms is first prompted by sense-perception. This leaves open the possibility that once that critical awareness of the Forms is established, further reflection at a conceptual level may lead to continued recollection and learning without further input from the senses, and that this approach is what is recommended for the more advanced philosopher. Hence the position endorsed by Socrates in the Phaedo, recommending that the philosopher get in training for death, fleeing as far as is possible from the bodily senses which only distract, is consistent with the position on sense perception in the Recollection argument. The senses are treated as a necessary prompt to reflection, not because they provide our best source of knowledge, but because we start life tied to the senses and believing their objects important.

The financial crisis has led to calls for increased regulation of the financial sector. In many respects this is uncontroversial because increased regulation should promote the behaviours we want to see, while limiting the behaviours we do not. This article takes issue with the idea that regulation, and guidelines, promote ethical behaviour in the way that we want them to. Firstly, judgement is often required to implement guidelines and regulations, which allows room for unethical behaviour. Secondly, we want financial professionals (...) to behave ethically even when there are significant incentives not to; so, verifying compliance with regulations and guidelines when such incentives are absent isn’t a good gauge of the ethical status of financial professionals. -/- The example of the valuation of the assets (Net Asset Value) of hedge funds illustrates these issues well. There are many rules governing how NAVs should be calculated, and while we can verify that a fund is abiding by the rules, the ability to manipulate the NAV remains. Furthermore, the incentive to do so is often only present during a crisis (usually to understate losses). Therefore, verifying compliance during ‘normal’ times is of little help in judging whether a manager will behave ethically when we most need him to. I first argue that the gap between compliance with regulations and ethical behaviour is best filled by the adoption of a virtue ethics approach, as discussed by Spalding & Oddo (2011), and Graafland & van de Ven (2011). I then discuss the implications of adopting such an approach for the financial industry’s codes of conduct, such as the CFA Institute’s ‘Code of Ethics and Standards of Professional Conduct’. Adopting a virtue ethics perspective would require a significant change in the emphasis of such codes. (shrink)

In this paper I argue the best examples of the methods in the evolutionary social sciences don’t actually resemble either of the two methods called “Adaptive Thinking” or “Reverse Engineering” described by evolutionary psychologists. Both AT and RE have significant problems. Instead, the best adaptationist work in the ESSs seems to be based on and is aiming at a different method that avoids the problems of AT and RE: it is a behavioral level method that starts with information (...) about both the trait in question and knowledge of the EEA. I describe some examples from the literature, and suggest how a behavioral level ESS might still contribute to the discovery and understanding of human psychology. Finally, I describe some remaining problems for adaptationist reasoning of this kind. (shrink)

Dominant paradigms in science foster integration of research findings, but at what cost? Forcing convergence requires centralizing decision-making authority, and risks reducing the diversity of methods and contributors, both of which are essential for the breakthrough ideas that advance science.

Research in the Unites States concerning the relative access of women and men to financial resources has focused on the influence of women's increasing market work but has largely overlooked the also critical issue of what happens to money after it enters couple households. To fill this gap, this article employs a typology of household allocative systems developed in Great Britain to analyze money management and control in a sample of U.S. couples drawn from the Fragile Families and Child Wellbeing (...) Study. I find that the use of these systems varies substantially across socioeconomic, racial, ethnic, and relationship status groups, as well as by partners' relative household contributions. The patterns suggest that many women, already disadvantaged in earnings, either absolutely or relative to their partners, are in couples in which men's control over or withholding of income may reproduce or exacerbate their earnings disadvantage.

ABSTRACTThe negativity bias is the tendency for individuals to give greater weight, and often exhibit more rapid and extreme responses, to negative than positive information. Using the Deese-Roediger-McDermott illusory memory paradigm, the current study sought to examine how the negativity bias might affect both correct recognition for negative and positive words and false recognition for associated critical lures, as well as how trait neuroticism might moderate these effects. In two experiments, participants studied lists of words composed of semantic associates of (...) an unpresented word. Half of the lists were comprised of positive words and half were comprised of negative words. As expected, individuals remembered negative list words better than positive list words, consistent with a negativity bias in correct recognition. When tested immediately, individuals also exhibited greater false memory for negative versus positive critical lures. When tested after a 24-hr delay... (shrink)

The premise of biological modularity is an ontological claim that appears to come out of practice. We understand that the biological world is modular because we can manipulate different parts of organisms in ways that would only work if there were discrete parts that were interchangeable. This is the foundation of the BioBrick assembly method widely used in synthetic biology. It is one of a number of methods that allows practitioners to construct and reconstruct biological pathways and devices using DNA (...) libraries of standardized parts with known functions. In this paper, we investigate how the practice of synthetic biology reconfigures biological understanding of the key concepts of modularity and evolvability. We illustrate how this practice approach takes engineering knowledge and uses it to try to understand biological organization by showing how the construction of functional parts and processes can be used in synthetic experimental evolution. We introduce a new approach within synthetic biology that uses the premise of a parts-based ontology together with that of organismal self-organization to optimize orthogonal metabolic pathways in E. coli. We then use this and other examples to help characterize semisynthetic categories of modularity, parthood, and evolvability within the discipline. (shrink)

Evaluative processes have their roots in early evolutionary history, as survival is dependent on an organism’s ability to identify and respond appropriately to positive, rewarding or otherwise salubrious stimuli as well as to negative, noxious, or injurious stimuli. Consequently, evaluative processes are ubiquitous in the animal kingdom and are represented at multiple levels of the nervous system, including the lowest levels of the neuraxis. While evolution has sculpted higher level evaluative systems into complex and sophisticated information-processing networks, they do not (...) come to replace, but rather to interact with more primitive lower level representations. Indeed, there are basic features of the underlying neuroarchitectural plan for evaluative processes that are common across levels of organization—including that of evaluative bivalence. (shrink)

Studies exploring how students learn and understand science processes such as diffusion and natural selection typically find that students provide misconceived explanations of how the patterns of such processes arise (such as why giraffes’ necks get longer over generations, or how ink dropped into water appears to “flow”). Instead of explaining the patterns of these processes as emerging from the collective interactions of all the agents (e.g., both the water and the ink molecules), students often explain the pattern as being (...) caused by controlling agents with intentional goals, as well as express a variety of many other misconceived notions. In this article, we provide a hypothesis for what constitutes a misconceived explanation; why misconceived explanations are so prevalent, robust, and resistant to instruction; and offer one approach of how they may be overcome. In particular, we hypothesize that students misunderstand many science processes because they rely on a generalized version of narrative schemas and scripts (referred to here as a Direct-causal Schema) to interpret them. For science processes that are sequential and stage-like, such as cycles of moon, circulation of blood, stages of mitosis, and photosynthesis, a Direct-causal Schema is adequate for correct understanding. However, for science processes that are non-sequential (or emergent), such as diffusion, natural selection, osmosis, and heat flow, using a Direct Schema to understand these processes will lead to robust misconceptions. Instead, a different type of general schema may be required to interpret non-sequential processes, which we refer to as an Emergent-causal Schema. We propose that students lack this Emergent Schema and teaching it to them may help them learn and understand emergent kinds of science processes such as diffusion. Our study found that directly teaching students this Emergent Schema led to increased learning of the process of diffusion. This article presents a fine-grained characterization of each type of Schema, our instructional intervention, the successes we have achieved, and the lessons we have learned. (shrink)

Organelles transported along microtubules are normally moved to precise locations within cells. For example, synaptic vesiceles are transported to the neruronal synapse, the Golgi apparatus is generally found in a perinuclear location, and the membranes of the endoplasmic reticulum are actively extended to the cell periphery. The correct positioning of these organelles depends on microtubules and microtubule motors. Melanophores provide an extreme example of organized organelle transport. These cells are specialized to transport pigment granules, which are coordinately moved towards or (...) away from the cell center, and result in the cell appearing alternately light or dark. Melanophores have proved to be an ideal system for studying the mechanisms by which the cell controls the direction of its organelle transport. Pigment granule dispersion (the movement away from the cell center) requires protein phosphorylation, while pigment aggregation (the movement towards the cell center) requires protein dephosphorylation. The target of this phosphorylation and dephosphorylation event is a protein that interacts with the microtubule motor protein, kinesin. Thus, the direction of organelle transport along microtubules may be regulated by controlling the activity of a microtubule motor. (shrink)

As crucial interface organs gut and skin have much in common. Therefore it is unsurprising that several gut pathologies have skin co‐morbidities. Nevertheless, the reason for this remains ill explored, and neither mainstream gastroenterology nor dermatology research have systematically investigated the ‘gut‐skin axis'. Here, in reviewing the field, we propose several mechanistic levels on which gut and skin may interact under physiological and pathological circumstances. We focus on the gut microbiota, with its huge metabolic capacity, and the role of dietary (...) components as potential principle actors along the gut‐skin axis. We suggest that metabolites from either the diet or the microbiota are skin accessible. After defining open key questions around the nature of these metabolites, how they are sensed, and which cutaneous changes they can induce, we propose that understanding of these pathways will lead to novel therapeutic strategies based on targeting one organ to improve the health of the other.

I explore some enlightening alternative economic theories in Plato’s Republic which help to cast doubt on standard models of rationality in economics. Starting from Socrates’ suggestion that things work best if everyone says ‘mine’ about the same things, I discuss a kind of ‘belonging’ which merits more attention in political and economic theory. This kind of belonging is not about owning property, but it can (better) explain the desire to do things for others and for the collective good. But (...) did Socrates forget to invoke it when addressing the puzzle about why the philosopher would willingly return to the cave? (shrink)

Psychiatry is rapidly adopting digital phenotyping and artificial intelligence/machine learning tools to study mental illness based on tracking participants’ locations, online activity, phone and text message usage, heart rate, sleep, physical activity, and more. Existing ethical frameworks for return of individual research results (IRRs) are inadequate to guide researchers for when, if, and how to return this unprecedented number of potentially sensitive results about each participant’s real-world behavior. To address this gap, we convened an interdisciplinary expert working group, supported by (...) a National Institute of Mental Health grant. Building on established guidelines and the emerging norm of returning results in participant-centered research, we present a novel framework specific to the ethical, legal, and social implications of returning IRRs in digital phenotyping research. Our framework offers researchers, clinicians, and Institutional Review Boards (IRBs) urgently needed guidance, and the principles developed here in the context of psychiatry will be readily adaptable to other therapeutic areas.

The research described here contributes to the extant empirical research on business ethics education by examining outcomes drawn from the literature on positive organizational scholarship (POS). The general research question explored is whether a course on ethical decision-making in business could positively influence students’ confidence in their abilities to handle ethical problems at work (i.e., moral efficacy), boost the relative importance of ethics in their work lives (i.e., moral meaningfulness), and encourage them to be more courageous in raising ethical problems (...) at work even if it is unpopular (i.e., moral courage). Specifically, the study used a rigorous quasi-experimental pretest–posttest research design with a treatment (N = 30) and control group (N = 30) to investigate whether a graduate-level course in business ethics could influence students’ levels of moral efficacy, meaningfulness, and courage. Findings revealed that participants in the business ethics treatment course experienced significant positive increases in each of the three outcome variables as compared to the control group. The largest increase was in moral efficacy, followed by moral courage, and finally, moral meaningfulness. These findings are discussed in the context of the current research on business ethics education and POS. Implications for future research are discussed. (shrink)

This study adapted and tested the efficacy of the Red-Light Purple-Light games for improving executive function skills in preprimary classrooms in Nairobi, Kenya. A cluster randomized controlled trial was used to evaluate the efficacy of the adapted RLPL intervention. Specifically, 24 centers were randomized to the RLPL or a wait-list control condition. Consistent with previous studies, participating classrooms delivered 16 lessons across an 8-week intervention period. A total of 479 children were recruited into the study. After exclusions based on child (...) age and data quality, 451 and 404 children had completed computerized assessments of EF skills at pre- and posttest assessments, respectively. Children in the RLPL centers did not demonstrate any improvements in EF skills relative to their peers in the wait-list control condition. Exploratory tests of moderators were also all null. Results are discussed with respect to measurement limitations and contextual factors that may explain the null results of RLPL on EF skills in young children in Kenya. (shrink)

Mobile devices with health apps, direct-to-consumer genetic testing, crowd-sourced information, and other data sources have enabled research by new classes of researchers.

The article recommends a series of measures, including education, consultation, transparency, self-governance, and regulation to strike the appropriate balance. (shrink)

Background:Clinical investigation is a growing field employing increasing numbers of nurses. This has created a new specialty practice defined by aspects unique to nursing in a clinical research context: the objectives, setting, and nature of the nurse–participant relationship. The clinical research nurse role may give rise to feelings of ethical conflict between aspects of protocol implementation and the duty of patient advocacy, a primary nursing responsibility. Little is known about whether research nurses experience unique ethical challenges distinct from those experienced (...) by nurses in traditional patient-care settings.Research objectives:The purpose of the study was to describe the nature of ethical challenges experienced by clinical research nurses within the context of their practice.Research design:The study utilized a qualitative descriptive design with individual interviews.Participants and research context:Participating nurses self-identified as having experienced ethical challenges during screening. The majority were Caucasian, female, and worked in outpatient settings. Approximately 50% had > 10 years of research experience.Ethical considerations:The human subjects review board approved the study. Written informed consent was obtained.Findings:Predominant themes were revealed: the inability to provide a probable good, or/do no harm, and dual obligations. The following patterns and subthemes emerged: conflicted allegiances between protocol implementation, needs of the participant, desire to advance science, and tension between the nurse–patient therapeutic relationship versus the research relationship.Discussion:Participants described ethical challenges specific to the research role. The issues are central to the nurse–participant relationship, patient advocacy, the nurse’s role in implementing protocols, and/or advancing science.Conclusion:Ethical challenges related to the specialized role of clinical research nurses were identified. More research is warranted to fully understand their nature and frequency and to identify support systems for resolution. (shrink)

This paper explores how Charles Peirce’s habit-based epistemology leads him to theorise perception. I show how Peirce’s triadic semiotic analysis of perceptual judgment renders his theory of perception neither a representationalism nor a relationism /direct realism, but an interesting hybrid of the two. His view is also extremely interesting, I argue, in the way that by analysing symbols as habits it refuses the common assumption that perception is an affair best understood synchronically, as a ‘language-entry event’. Relatedly, I extend (...) previous work (Legg 2008) which argues that Peirce’s epistemology counts as a ‘hyperinferentialism’ in Robert Brandom’s terms, but this does not mean that Peirce’s theory of perception cannot accommodate unmediated contact with reality - what Peirce called ‘the outward clash’.

Quelle est l'intention de Platon lorsqu'il fait de Socrate un virtuose de l'étymologie dans le Cratyle? Préciser les rapports entre la " science des lettres " qui se constitue en son siècle et la nouvelle théorie des Idées qu'il élabore. Socrate s'entretient avec le jeune Hermogène puis avec l'énigmatique Cratyle des rapports entre les mots et les choses. La rectitude des noms est-elle affaire de convention, ainsi que le soutient Hermogène? Ou s'agit-il d'un accord " naturel ", comme le prétend (...) Cratyle? Découvre-t-on cet accord par science ou par inspiration? Au terme du débat, après avoir mis à l'épreuve toutes les ressources de la " science des lettres ", Socrate propose une nouvelle théorie du nom, instrument faillible construit pour faire voir la réalité en la minant. Il dessine aussi un ordre des priorités : il faut d'abord connaître les êtres, puis les noms. " Savoir comment il faut apprendre ou découvrir les êtres, peut-être est-ce là trop lourde tâche pour toi et moi! C'est déjà beau de reconnaître qu'il ne faut pas partir des noms. ". (shrink)

A limiting factor in ethics education in medical training has been difficulty in assessing competence in ethics. This study was conducted to test the concept that content analysis of pediatric residents’ personal reflections about ethics experiences can identify changes in ethical sensitivity and reasoning over time. Analysis of written narratives focused on two of our ethics curriculum’s goals: 1) To raise sensitivity to ethical issues in everyday clinical practice and 2) to enhance critical reflection on personal and professional values as (...) they affect patient care. Content analysis of written reflections was guided by a tool developed to identify and assess the level of ethical reasoning in eight domains determined to be important aspects of ethical competence. Based on the assessment of narratives written at two times (12 to 16 months/apart) during their training, residents showed significant progress in two specific domains: use of professional values, and use of personal values. Residents did not show decline in ethical reasoning in any domain. This study demonstrates that content analysis of personal narratives may provide a useful method for assessment of developing ethical sensitivity and reasoning. (shrink)

The Adverse Outcome Pathway (AOP) concept is a knowledge assembly and communication tool to facilitate the transparent translation of mechanistic information into outcomes meaningful to the regulatory assessment of chemicals. The AOP framework and associated knowledgebases (KBs) have received significant attention and use in the regulatory toxicology community. However, it is increasingly apparent that the potential stakeholder community for the AOP concept and AOP KBs is broader than scientists and regulators directly involved in chemical safety assessment. In this paper we (...) identify and describe those stakeholders who currently—or in the future—could benefit from the application of the AOP framework and knowledge to specific problems. We also summarize the challenges faced in implementing pathway-based approaches such as the AOP framework in biological sciences, and provide a series of recommendations to meet critical needs to ensure further progression of the framework as a useful, sustainable and dependable tool supporting assessments of both human health and the environment. Although the AOP concept has the potential to significantly impact the organization and interpretation of biological information in a variety of disciplines/applications, this promise can only be fully realized through the active engagement of, and input from multiple stakeholders, requiring multi-pronged substantive long-term planning and strategies.

ObjectiveOverweight and obesity [body mass index ≥ 25 kg/m2] are associated with poorer prognosis among women with breast cancer, and weight gain is common during treatment. Symptoms of depression and anxiety are also highly prevalent in women with breast cancer and may be exacerbated by post-diagnosis weight gain. Altered brain function may underlie psychological distress. Thus, this secondary analysis examined the relationship between BMI, psychological health, and resting state functional connectivity among women with breast cancer.MethodsThe sample included 34 post-menopausal women (...) newly diagnosed with Stage 0-IIa breast cancer who were enrolled in a 6-month randomized controlled trial of aerobic exercise vs. usual care. At baseline prior to randomization, whole-brain analyses were conducted to evaluate the relationship between BMI and seed-to-voxel rsFC of the hippocampus and amygdala. Connectivity values from significant clusters were then extracted and examined as predictors of self-reported depression and anxiety.ResultsMean BMI was in the obese range. For both seeds examined, higher BMI was associated with lower rsFC with regions of prefrontal cortex, including ventrolateral PFC, dorsolateral PFC, and superior frontal gyrus. Hippocampal connectivity with the vlPFC was negatively correlated with self-reported anxiety.ConclusionHigher BMI was associated with lower hippocampal and amygdala connectivity to regions of PFC implicated in cognitive control and emotion regulation. BMI-related differences in hippocampal and amygdala connectivity following a recent breast cancer diagnosis may relate to future worsening of psychological functioning during treatment and remission. Additional longitudinal research exploring this hypothesis is warranted. (shrink)

Recent extensions of mechanistic explanation into psychology suggest that cognitive models are only explanatory insofar as they map neatly onto, and serve as scaffolding for more detailed neural models. Filling in those neural details is what these accounts take the integration of cognitive psychology and neuroscience to mean, and they take this process to be seamless. Critics of this view have given up on cognitive models possibly explaining mechanistically in the course of arguing for cognitive models having explanatory value independent (...) of how well they align with neural mechanisms. We can have things both ways, however. The problem with seamless integration accounts is their seamlessness, not that they take cognitive models to be mechanistic. A non-componential view of mechanisms allows for cognitive and neural models that cross cut one another, and for cognitive models that don’t decompose into parts. I illustrate the inadequacy of seamless accounts of integration by contrasting how “filter” models of attention in psychology and of sodium channels in neuroscience developed; by questioning whether the mappings generated by neuroimaging subtraction studies achieve integration; and by reinterpreting the evidence for cognitive models of memory having been successfully integrated with neural models. I argue that the integrations we can realistically expect are more partial, patchy, and full of loose threads than the mosaic unity Craver describes. (shrink)

Faced with the difficult task of discerning Plato’s true ideas from the contradictory voices he used to express them, scholars have never fully made sense of the many incompatibilities within and between the dialogues. In the magisterial _Plato’s Philosophers_, Catherine Zuckert explains for the first time how these prose dramas cohere to reveal a comprehensive Platonic understanding of philosophy. To expose this coherence, Zuckert examines the dialogues not in their supposed order of composition but according to the dramatic order (...) in which Plato indicates they took place. This unconventional arrangement lays bare a narrative of the rise, development, and limitations of Socratic philosophy. In the drama’s earliest dialogues, for example, non-Socratic philosophers introduce the political and philosophical problems to which Socrates tries to respond. A second dramatic group shows how Socrates develops his distinctive philosophical style. And, finally, the later dialogues feature interlocutors who reveal his philosophy’s limitations. Despite these limitations, Zuckert concludes, Plato made Socrates the dialogues’ central figure because Socrates raises the fundamental human question: what is the best way to live? Plato’s dramatization of Socratic imperfections suggests, moreover, that he recognized the apparently unbridgeable gap between our understandings of human life and the nonhuman world. At a time when this gap continues to raise questions—about the division between sciences and the humanities and the potentially dehumanizing effects of scientific progress—Zuckert’s brilliant interpretation of the entire Platonic corpus offers genuinely new insights into worlds past and present.

The rapid advancement of artificial intelligence has brought about significant positive changes across various sectors. However, it has also created new opportunities for cybercrime. Nigeria, in particular, has witnessed a surge in cybercriminal activities, which have had severe economic and social consequences.

It discussed the ethical implications of AI, cybercrime, and the underground business economy, highlighting (...) potential risks to privacy, security, and social trust, while emphasizing the ethical responsibilities of AI developers, policymakers, and stakeholders in mitigating these risks and promoting responsible AI use. The Igwebuike ethical theoretical framework was employed for the evaluation of cybercrime, and the thematic and analytical methods of inquiry were used. The paper submits that there is need for an ethical response to the challenges posed by cybercrime in Nigeria. (shrink)

Tetris provides a difficult, dynamic task environment within which some people are novices and others, after years of work and practice, become extreme experts. Here we study two core skills; namely, choosing the goal or objective function that will maximize performance and a feature-based analysis of the current game board to determine where to place the currently falling zoid so as to maximize the goal. In Study 1, we build cross-entropy reinforcement learning models to determine whether different goals result in (...) different feature weights. Two of these optimization strategies quickly rise to performance plateaus, whereas two others continue toward higher but more jagged heights. In Study 2, we compare the zoid placement decisions made by our best CERL models with those made by 67 human players. Across 370,131 human game episodes, two CERL models picked the same zoid placements as our lowest scoring human for 43% of the placements and as our three best scoring experts for 65% of the placements. Our findings suggest that people focus on maximizing points, not number of lines cleared or number of levels reached. They also show that goal choice influences the choice of zoid placements for CERLs and suggest that the same is true of humans. Tetris has a repetitive task structure that makes Tetris more tractable and more like a traditional experimental psychology paradigm than many more complex games or tasks. Hence, although complex, Tetris is not overwhelmingly complex and presents a right-sized challenge to cognitive theories, especially those of integrated cognitive systems. (shrink)
