An absolute decline in US life expectancy in low education whites has alarmed policy makers and attracted media attention. Depending on which studies are correct, low education white women have lost between 3 and 5 years of lifespan; men, between 6 months and 3 years. Although absolute declines in life expectancy are relatively rare, some commentators see the public alarm as reflecting a racist concern for white lives over black ones. How ought we ethically to evaluate this lifespan contraction in (...) low education whites? Should we care, or is it racist to care? Does it constitute an injustice or reflect justice being done? I argue that the lifespan contraction in low education whites violates key normative criteria used to make determinations of health justice, and that these judgments do not vitiate concerns about racism. I conclude with reflections on US population health policy and building an inclusive health equity movement. (shrink)

Previous research has established that the success of strikes, and social movements more broadly, depends on their ability to garner support from the public. However, there is scant published research investigating the response of the public to strike action by healthcare workers. In this study, we address this gap through a study of public responses to UK nursing strikes in 2022–2023, using a data set drawn from Twitter of more than 2300 publicly available tweets. We focus on negative tweets, investigating (...) which societal discourses social media users draw on to oppose strike action by nurses. Using a combination of corpus‐based approaches and discourse analysis, we identified five categories of opposition: (i) discourse discrediting nurses; (ii) discourse discrediting strikes by nurses; (iii) discourse on the National Health System; (iv) discourse about the fairness of strikers' demands and (v) discourse about potential harmful impact. Our findings show how social media users operationalise wider societal discourses about the nursing profession (e.g., associations with care, gender, vocation and sacrifice) as well as recent crises such as the Covid‐19 pandemic to justify their opposition. The results also provide valuable insights into misconceptions about nursing, strike action and patient harm, which can inform strategies for public communication. (shrink)

Current advances in assisted reproductive technologies aim to promote the health and well-being of future children. They offer the possibility to select embryos with the greatest potential of being born healthy (eg, preimplantation genetic testing) and may someday correct faulty genes responsible for heritable diseases in the embryo (eg, human germline genome modification (HGGM)). Most laws and policy statements surrounding HGGM refer to the notion of ‘serious’ as a core criterion in determining what genetic diseases should be targeted by these (...) technologies. Yet, this notion remains vague and poorly defined, rendering its application challenging and decision making subjective and arbitrary. By way of background, we begin by briefly presenting two conceptual approaches to ‘health’ and ‘disease’: objectivism (ie, based on biological facts) and constructivism (ie, based on human values). The basic challenge under both is sorting out whether and to what extent social and environmental factors have a role in helping to define what qualifies as a ‘serious’ disease beyond the medical criteria. We then focus on how a human rights framework (eg, right to science and right to the highest attainable health) could integrate the concepts of objectivism and constructivism so as to provide guidance for a more actionable consideration of ‘serious’. Ultimately, it could be argued that a human rights framework, by way of its legally binding nature and its globally accepted norms and values, provides a more universal foundation for discussions of the ethical, legal and social implications of emerging or disruptive technologies.

Existing whistle-blowing models rely on “cold” economic calculations and cost-benefit analyses to explain the judgments and actions of potential whistle-blowers. I argue that “hot” cognitions – value conflict and emotions – should be added to these models. I propose a model of the whistle-blowing decision process that highlights the reciprocal influence of “hot” and “cold” cognitions and advocate research that explores how value conflict and emotions inform reporting decisions. I draw on the cognitive appraisal approach to emotions and on the (...) social-functional value pluralism model to generate propositions. (shrink)

The paper investigates various definitions of the concept of opinion as opposed to factual or evidence-based statements and proposes a taxonomy of opinions expressed in English as identified in selected social media. A discussion situates opinions in the realm of pragmatics and reaches to philosophy of language and cognitive science. The research methodology combines a thorough linguistic analysis of opinions, proposing their multifaceted taxonomy with the automatically generated lexical embeddings of positive and negative lexicon acquired from the analysed opinionated texts. (...) As proposed, the definition of the concept of opinion is best apprehended when looked upon in terms of an opinion event, with a number of necessary conditions on the one hand, and those that are characteristic of an explicit opinion prototype on the other. Lists of opinion discourse markers show their preferential uses either in positive or negative opinionated texts; however, no sets of necessary and/or sufficient opinion markers properties have been acquired from the analysed texts. The conclusions indicate a polysemous understanding of naturally occurring social media opinionated texts and a definitional flexibility of the boundaries around lexical positive and negative types of opinion markers.

The increasing concern about ethics and integrity in research communities has brought attention to how students and junior academics can be trained on this regard. Moreover, it is known that ethical behaviour and integrity not only involve individual but also group norms and considerations. Thus, through action research and participant observation, this research investigates the learning processes through which 64 students collaboratively develop research ethics and integrity competencies. The aim was to understand how bachelor, master and PhD students approach ethical (...) dilemma cases through a collaborative process. The data consisted of recorded group work on ethics cases, student group reports, and post-training questionnaires. Later, the analyses considered groups as the unit of analysis. These data were analysed through content analysis utilizing the SOLO taxonomy to identify levels of understanding and assess evolvement of ethical sensitivity during a case-based training session. The results show that all groups reached the level of understanding where the groups demonstrated that concepts had been understood appropriately, but occasionally struggled to make connections between them. Students perceived working collaboratively as beneficial. The results help teachers of research ethics and integrity to make pedagogically justified choices in their teaching. Drawing on the results of this study, we propose a tool for the formative assessment of student learning of research ethics and integrity. (shrink)

The study focused on university students' understanding and conceptions of ethical issues in research. Domain-specific and domain-transcending measures were developed to gauge the students' awareness of ethical issues. Responses were obtained from 269 undergraduate and graduate students at a U.S. regional university. Participant withdrawal, the debriefing of research participants, the dissemination of findings, and giving credit to co-contributors were the most challenging ethical issues for the students. Ethical awareness was predicted by professional and organizational socialization, and perspective taking. Contextualization greatly (...) improved the students' ability to recognize ethical issues. Simulations and role-taking are suggested as the means with which to teach students about the ethical issues perceived as challenging. (shrink)

The focus of this article is university teachers’ and students’ views of plagiarism, plagiarism detection, and the use of plagiarism detection software as learning support. The data were collected from teachers and students who participated in a pilot project to test plagiarism detection software at a major university in Finland. The data were analysed through factor analysis, T-tests and inductive content analysis. Three distinct reasons for plagiarism were identified: intentional, unintentional and contextual. The teachers did not utilise plagiarism detection to (...) support student learning to any great extent. We discuss the pedagogical implications and suggest that the contextual reasons for plagiarism require focus primarily on study strategies, whereas the intentional reasons require profound discussion about attitudes and conceptions of good learning and university-level study habits.

This book deals with the impact of the Reformation debate in Germany on the most prominent intellectual movement of the time: humanism Although it is true that humanism influenced the course of the Reformation, says Erika Rummel, the dynamics of the relationship are better described by saying that humanism was co-opted, perhaps even exploited, in the religious debate.

This open access book explores the gendered reality of learning philosophy at the university level, investigating the ways in which women and minority students become alienated from the social practices of a male-dominated field, and examining pedagogical solutions to this problem. It covers the roles and the interactions of the professor and student in the following ways: (1) the historical situation, (2) the affective, social and bodily situation, and (3) the moral situation. This text analyzes women’s passion for philosophy as (...) a quest for truth, as well as their partial alienation from the social practices of philosophy. It demonstrates that recognition, generosity, and care are central ingredients of good learning and teaching experiences. Providing case studies of experimental courses in philosophy, the book discusses a variety of pedagogical approaches that might increase the inclusiveness of a philosophical education: novel and more gender-balanced ways of interpreting the history of philosophy, problem-based learning as a means of emancipating the student from the traditional master–disciple relationship, body awareness practices as a way of challenging the “disembodying” tendencies of philosophy, and a pluralism of methods to address the needs of different kinds of learners. Thanks to these features, the book is particularly useful for philosophy professors at the university level, but it also provides insights for all readers who feel puzzled about the persistent underrepresentation of women in philosophy.

Despite apparent political concern and action—often fuelled by high-profile cases and campaigns—legislative and institutional responses to image-based sexual abuse in the UK have been ad hoc, piecemeal and inconsistent. In practice, victim-survivors are being consistently failed: by the law, by the police and criminal justice system, by traditional and social media, website operators, and by their employers, universities and schools. Drawing on data from the first multi-jurisdictional study of the nature and harms of, and legal/policy responses to, image-based sexual abuse, (...) this article argues for a new joined-up approach that supports victim-survivors of image-based sexual abuse to ‘reclaim control’. It argues for a comprehensive, multi-layered, multi-institutional and multi-agency response, led by a government- and industry-funded online or e-safety organisation, which not only recognises the diversity of victim-survivor experiences and the intersection of image-based sexual abuse with other forms of sexual and gender-based violence and discrimination, but which also enables victim-survivors to reclaim control within and beyond the criminal justice system.

Background This paper describes the design, implementation, and process outcomes from three public deliberations held in three tribal communities. Although increasingly used around the globe to address collective challenges, our study is among the first to adapt public deliberation for use with exclusively Indigenous populations. In question was how to design deliberations for tribal communities and whether this adapted model would achieve key deliberative goals and be well received.Methods We adapted democratic deliberation, an approach to stakeholder engagement, for use with (...) three tribal communities to respect tribal values and customs. Public deliberation convenes people from diverse backgrounds in reasoned reflection and dialogue in search of collective solutions. The deliberation planning process and design were informed by frameworks of enclave deliberation and community-based participatory research, which share key egalitarian values. The deliberations were collaboratively designed with tribal leadership and extensive partner input and involvement in the deliberations. Each deliberation posed different, locally relevant questions about genomic research, but used the same deliberation structure and measures to gauge the quality and experience of deliberation.Results A total of 52 individuals participated in the deliberations across all three sites. Deliberants were balanced in gender, spanned decades in age, and were diverse in educational attainment and exposure to health research. Overall, the deliberations were positively evaluated. Participant perceptions and external observer datasets depict three deliberations that offered intensive conversation experiences in which participants learned from one another, reported feeling respected and connected to one another, and endorsed this intensive form of engagement.Conclusion The adapted deliberations achieved key deliberative goals and were generally well received. Limitations of the study are described. (shrink)

Our aim was to identify the ethical issues faced by students in the behavioral and natural sciences during their doctoral programmes. The participants were 28 PhD students who were interviewed about their doctoral study and supervision experiences. We identified a total of 102 ethical issues compromising the principles of nonmaleficence, beneficence, autonomy, justice, or fidelity. There were some differences in emphases, with the students in the behavioral sciences displaying a broader range of ethical compromises than the students in the natural (...) sciences. Ethical problems emerged in the individual supervisor–student relationships, but often problems involving the scholarly community appeared in the background. (shrink)

: The main contribution of this paper to current philosophical and sociological studies on modeling is to analyze modeling as an object-oriented interdisciplinary activity and thus to bring new insights into the wide, heterogeneous discourse on tools, forms and organization of interdisciplinary research. A detailed analysis of interdisciplinarity in the making of models is presented, focusing on long-standing interdisciplinary collaboration between specialists in infectious diseases, mathematicians and computer scientists. The analysis introduces a novel way of studying the elements of the (...) models as carriers of interdisciplinarity. These elements, being functionally interdependent building blocks, evolve during the modeling work and carry the disciplinary tensions in the process. This shows how the long and challenging process of defining and reformulating the object of research is crucial for understanding the dynamics of interdisciplinarity in the making. (shrink)

This article describes research-based role-play on academic integrity. In the role-play, doctoral students negotiated the revision of an institutional integrity policy representing different groups of academics and students. On the one hand, role-play as a teaching method and learning activity demonstrated the difficulty of accommodating different perspectives; on the other, it showed the power and necessity of negotiation in matters that involve value judgments. The role-play is described in detail along with its underlying pedagogical foundations and its contextualisation in a (...) doctoral summer school where it took place. The purpose of the article is to describe how academic integrity was approached through role-play and to discuss theoretical and pedagogical foundations of role-play in teaching academic integrity. Although the article does not describe empirical research on role-play as a teaching method, it demonstrates how role-play in teaching academic integrity was developed based on prior research on the topic.

This paper focuses on Confucian formulations of personhood and the implications they may have for bioethics and medical practice. We discuss how an appreciation of the Confucian concept of personhood can provide insights into the practice of informed consent and, in particular, the role of family members and physicians in medical decision-making in societies influenced by Confucian culture. We suggest that Western notions of informed consent appear ethically misguided when viewed from a Confucian perspective.

Patients with amyotrophic lateral sclerosis (ALS) face many difficult, timing-sensitive decisions over the course of their illness, weighing present versus future harms and benefits. Supplemented by interviews with people with ALS, we argue for a relational approach to understanding these decisions and their effects on identity. We highlight two critical aspects of the patient–caregiver relationship: (1) the extent to which each may rely on the other leaves their wellbeing intimately intertwined and (2) patients often require others to help with the (...) imaginative task of considering possible futures for each therapeutic option. We show why family involvement in decisionmaking practices can be so critical, and shed light on the ways intimate others help preserve and protect people’s identities amidst the destabilizing uncertainty illness and treatment can bring.

In this reply, we wish to defend our original position and address several of the points raised by two excellent responses. The first response (De Miguel Beriain) questions the relevance of the notion of ‘serious’ within the context of human germline genome modification (HGGM). We argue that the ‘serious’ factor is relevant and that there is a need for medical and social lenses to delineate the limits of acceptability and initial permissible applications of HGGM. In this way, ‘serious’ acts as (...) a starting point for further discussions and debates on the acceptability of the potential clinical translation of HGGM. Therefore, there is a pressing need to clarify its scope, from a regulatory perspective, so as to prevent individuals from using HGGM for non-therapeutic or enhancement purposes. The second response (Kalsi) criticizes the narrow interpretation of the objectivist approach and the apparent bias towards material innovations when discussing the right to benefit from scientific advancements. As an in-depth discussion of the objectivist and constructivist approaches was beyond the scope of our original paper, we chose to focus on one specific objectivist account, one which focuses on biological and scientific facts. We agree, however, with the critique that material innovations should not be the sole focus of the right to benefit from scientific advancements, which also incorporates freedom of scientific research and access to scientific knowledge scientific freedom and knowledge, including the influence of these on ethical thinking and cultures.

The aim of this study was to investigate the consequences of the use of text-matching software on teachers’ and students’ conceptions of plagiarism and problems in academic writing. An electronic questionnaire included scale items, structured questions, and open-ended questions. The respondents were 85 teachers and 506 students in a large Finnish university. Methods of analysis included exploratory factor analysis, t-test, and inductive content analysis. Both teachers and students reported increased awareness of plagiarism and improvements in writing habits, as well as (...) concerns and limitations related to the system. The results suggest that teachers are inclined to think of plagiarism as part of a learning process rather an issue of morality, which may have consequences for how they understand the role of text matching. The introduction of text-matching software has supported teachers’ work, but at the same time teachers emphasized their own responsibility in detecting problems in student writing. The survey provides a limited sample of “Case Finland,” where implementation of text-matching software nationwide has been remarkably rapid; it offers a glimpse into one institution’s implementation of a newly introduced policy for mandatory plagiarism detection.

Consequentialism is a moral philosophy that maintains that the moral worth of an action is determined by the consequences it has for the welfare of a society. Consequences of model design are a part of the model lifecycle that is often neglected. This paper investigates the issue using system dynamics modeling as an example. Since a system dynamics model is a product of the modeler’s design decisions, the modeler should consider the life cycle consequences of using the model. Seen from (...) a consequentialist perspective, the consequences of policies developed from system dynamics models determine the model’s moral value. This concept is explored by discussing model uncertainty from an engineering perspective. In this perspective, the ethical considerations shift from the behavior of the modeler to the model itself and the model’s inherent uncertainty. When the ethical considerations are taken away from the modeler and directed to what the model does, the ethical boundaries extend beyond the proximity of the model. This discussion renews the ethics conversation in system dynamics by considering this shift in philosophical perspective, and investigates how consequentialist moral philosophy applies to the modeling process and in communicating with decision-makers. A model of social assistance in Norway in the context of immigration pressures illustrates some possibilities for addressing these ethical concerns. This paper argues for an ethical framework, or at the very least, an ethical conversation within the field of system dynamics.Article first published online: 25 FEB 2017. (shrink)

This study focuses on the intersection of research ethics and academic writing, i.e. the use of sources, assignment of credit to the contributors in the research, and the dissemination of research findings. The study utilized a set of semi-structured and open-ended questions. The sample consisted of 269 undergraduate (BA) and graduate (MA) students at a U.S. university department of psychology including major and non-major students. The data showed that although an overwhelming number of the students’ examples related to ethical issues (...) in citation dealt with plagiarism, a broad range of examples of other types of issues were also provided. Understandably, students tended to view the questions about both the assignment of credit to those involved in conducting the research and the dissemination of research findings from the research participant’s perspective, which is more familiar to them than the researcher perspective. In order to help the students to expand their notions beyond the immediate own experience to a broader understanding for the ethical principles that ought to guide a researcher in his or her work, it is desirable that students be provided with opportunities to participate in authentic research projects. With a deeper understanding of the students’ conceptions of ethics in research and academic writing, we can become more attuned to the common limitations and misconceptions that students harbor, and thus better equipped to support students in their learning process.

Can one explain both the resilience of the status quo and the possibility for resistance from a subordinate position? This paper aims to resolve these seemingly incompatible perspectives. By extending Randall Collins's interaction ritual theory, and synthesizing it with Norbert Wiley's model of the self, this paper suggests how the emotional dynamics between people and within the self can explain social inertia as well as the possibility for resistance and change. Diverging from literature on the sociology of emotions that has (...) been concerned with individual emotional processes, this paper considers the collective level in order to explore how movement action is motivated. The emotional dynamics of subordinate positioning that limit women's options in face-to-face interactions are examined, as are the social processes of developing feminist consciousness and a willingness to participate in resistance work. Pointing toward empirical applications, I conclude by suggesting conditions where resistance is likely. (shrink)

By conceptualizing place-making as a dynamic process, this essay explores the history of two field sites that house long-term research projects in animal behavior: the Amboseli Baboon Project, cofounded by Jeanne Altmann in 1971, and Kay Holekamp’s Mara Hyena Project, which began in 1988. It highlights scientific place-making as crucial to the production of knowledge within behavioral ecology and invests our historical understanding of field sites with an appreciation for the intellectual processes that have transformed land into places for the (...) generation of scientific data.

Once common, therapeutic privilege—the practice whereby a physician withholds diagnostic or prognostic information from a patient intending to protect the patient—is now generally seen as unethical. However, instances of therapeutic privilege are common in some areas of clinical psychiatry. We describe therapeutic privilege in the context of borderline personality disorder, discuss the implications of diagnostic non-disclosure on integrated care and offer recommendations to promote diagnostic disclosure for this patient population. There are no data in this work.

Given the various shortcomings of classical phenomenological methods identified by critical and liberatory theorists, this paper considers what phenomenology has to offer theorists of multiply marginalized experience. The paper begins with an account of the major reasons for which Latinx feminists such as Linda Martín Alcoff, Jacqueline Martinez, and Mariana Ortega have found a phenomenological approach useful in their projects. This account reveals that though Latinx feminist phenomenologists have found useful resources for theorizing multiply marginalized theory and identity in the (...) classical texts of phenomenology, experiences unique to those subjected to marginalization remain significantly underdeveloped or absent from classical accounts. Taking seriously the primacy of lived experiences of ‘rupture’, this paper argues, is therefore necessary in the development of a phenomenological approach that does justice to life in the borderlands and the lived experience of being-between-worlds. Informed by the work of Latinx feminist theorists such as Gloria Anzaldúa and María Lugones, this paper closes with a proposed critical feminist phenomenological approach that centers the moment of ‘rupture’ described in such work. Ultimately, this paper argues that the communication and documentation of these ruptures in the form of phenomenological description allows for the examination and interrogation of sedimented logics of oppression on the way to liberatory ends.

Abstract:Many scientists argue that the world is becoming increasingly dominated by human activity, much to the detriment of the natural world. In what scholars have dubbed the Anthropocene, the current geological epoch during which time human activity has been the dominating force over climate and the environment, many questions of environmental ethics have arisen. Who does the earth belong to? What is the relationship between humans and the environment? What is the moral standing of non-human life? Locke and Rousseau provide (...) varying answers to these questions, which are central to discussions of environmental ethics. In many ways, Locke and Rousseau's answers are opposed to each other, suggesting a differing world view when it comes to environmental ethics. Locke's understanding of environmental ethics seems to dominate, and perhaps even cause, the onset of the Anthropocene, but Rousseau's response, and a potential turn toward his understanding of environmental ethics marks an ideological shift in the way that humans understand their relationship with the world around them. This paper argues that the writings of Locke and Rousseau correspond to different stages of the Anthropocene with significant effects on both environmental ethics and environmental governance and policy.

Editorial introduction to the Special Issue by Erika Goble, editor.

Childhood obesity may have severe long‐term consequences for health—indeed, for the overall course of a person's life. Do these harms amount to a problem of social justice? And if so, what should be done about it? Parents are usually granted considerable leeway to make decisions that affect their children's health. Social and moral theory has often overlooked the family, however, leaving us with an inadequateunderstanding of parental autonomy and of how social policy may influence it.

Intraspecific niche variation can differentially impact community processes and can represent the initial stages of adaptive radiation. Here we test for intraspecific differences in niche use in a keystone species, the alewife (Alosa pseudoharengus). To test whether feedbacks between predator foraging traits and prey communities have led to differences in niche use, we compare the diet composition and trophic position of anadromous and landlocked alewife populations. These populations differ in phenotypic traits related to foraging (gill raker spacing, gape width, and (...) prey selectivity). Trait differences appear to have resulted from eco-evolutionary feedbacks between alewives and their zooplankton prey, and suggest that these two life history forms are exploiting different niches. Direct diets show that anadromous alewives consume a greater biomass of predatory copepods than do landlocked alewives. Anadromous alewives also consume more ostracods—a littoral prey item—as the growing season progresses. These diet differences do not translate into a significant difference in trophic position, as estimated from stable isotopes. However, stable-isotope estimates of diet source show that during early fall, anadromous alewives obtain significantly more of their dietary carbon from the littoral food web. This increased reliance on littoral prey is likely a result of a diet switch that occurs in response to the alewife-driven exhaustion of large-bodied prey items available in the pelagic zone, i.e., alewife niche construction. These findings show the existence of important intraspecific niche differences in the alewife and support the role of eco-evolutionary feedbacks in shaping these niche differences. The initiation of alewife divergence is the result of dam building by humans. Therefore, alewife niche differentiation can be considered to be an eco-evolutionary byproduct of human cultural niche construction. (shrink)

A focused review of the literature on reasoning suggests that mechanisms based upon contraries are of fundamental importance in various abilities. At the same time, the importance of contraries in the human perceptual experience of space has been recently demonstrated in experimental studies. Solving geometry problems represents an interesting case as both reasoning abilities and the manipulation of perceptual–figural aspects are involved.In this study we focus on perceptual changes in geometrical problem solving processes in order to understand whether a mental (...) manipulation in terms of opposites might help. Four conditions were studied, two of which concerned the search for contraries as an implicit or explicit strategy.Results demonstrated that contraries, when used explicitly in solution processes, constitute an effective heuristic: The number of correct solutions increased, less time was needed to find a solution and participants were oriented towards the use of perception-based solutions—not only wer..

In this chapter I will present, in a general way, Millikan's biosemantic theory of the phenomenon of intentionality. For this purpose, the text will take the following path. First, I will present the problem of intentionality and an overview of the dominant theories of intentional content during the twentieth century and part of the twenty-first century. Then, I will present a general version of Millikan's biosemantic theory, appearing in 1984, which will allow us to see what the relevance and originality (...) of his proposal consists in. Finally, in keeping with one of the central purposes of Las filósofas que nos formaron, I will share a brief interview that Millikan very kindly agreed to give for this publication, in which she tells us some non-theoretical aspects of her history as a philosopher.
