In her paper, 'The Open Universe: Totality, Self-reference and Time', Ismael argues that the agent experience of dynamic time, in which the world comes into being, is more than 'mere appearance'. The key to her argument is that the actual world includes agents (minds) and their corresponding agential (mental) activity, which Ismael describes as 'the crucial step down from 'mere appearance' to actuality'. We present here a model of an agent as a complex physical system with a view to providing (...) a tenable illustration of Ismael's schema for understanding the 'actuality' of time. The radical implication for physical time as a result is that there is, in Ismael's words, 'no pure... conception of the way [the] world is independently of ourselves and our representational activity', but rather only 'embodied and engaged' knowledge of the world.

Costa and Shrapnel have recently proposed an interventionist theory of quantum causation. The formalism generalizes the classical methods of Pearl and allows for the discovery of quantum causal structure via localized interventions. Classical causal structure is presented as a special case of this more general framework. I introduce the account and consider whether this formalism provides a causal explanation for the Bell correlations.

Realist interpretations of quantum mechanics presuppose the existence of elements of reality that are independent of the actions used to reveal them. Such a view is challenged by several no-go theorems that show quantum correlations cannot be explained by non-contextual ontological models, where physical properties are assumed to exist prior to and independently of the act of measurement. However, all such contextuality proofs assume a traditional notion of causal structure, where causal influence flows from past to future according to ordinary (...) dynamical laws. This leaves open the question of whether the apparent contextuality of quantum mechanics is simply the signature of some exotic causal structure, where the future might affect the past or distant systems might get correlated due to non-local constraints. Here we show that quantum predictions require a deeper form of contextuality: even allowing for arbitrary causal structure, no model can explain quantum correlations from non-contextual ontological properties of the world, be they initial states, dynamical laws, or global constraints. (shrink)

Despite the tremendous empirical success of quantum theory there is still widespread disagreement about what it can tell us about the nature of the world. A central question is whether the theory is about our knowledge of reality, or a direct statement about reality itself. Current interpretations of quantum theory, regardless of their stance on this question, regard the Born rule as fundamental and add an independent state update (or ‘collapse’) rule to describe how quantum states change upon measurement. In (...) this paper we present an alternative perspective and derive a unified probability rule that subsumes both the Born rule and the collapse rule. We show that this more fundamental probability rule can provide a rigorous foundation for informational, or ‘knowledge-based’, interpretations of quantum theory. Our result requires an assumption of instrument non- contextuality, a key notion that generalises previous approaches to non-contextuality. Therefore, the framework also permits one to consider non-contextuality in scenarios with arbitrary causal structure. (shrink)

It is widely held that it is difficult, if not impossible, to apply causal theory to the domain of quantum mechanics. However, there are several recent scientific explanations that appeal crucially to quantum processes, and which are most naturally construed as causal explanations. They come from two relatively new fields: quantum biology and quantum technology. We focus on two examples, the explanation for the optical interferometer LIGO and the explanation for the avian magneto-compass. We analyse the explanation for the avian (...) magneto-compass from the perspective of Woodward's interventionist theory and provide a causal model. Furthermore, we show how worries expressed by Woodward about quantum causation are circumvented in these cases, concluding that these kinds of explanations are most naturally construed as causal.

Causal modelling provides a powerful set of tools for identifying causal structure from observed correlations. It is well known that such techniques fail for quantum systems, unless one introduces 'spooky' hidden mechanisms. Whether one can produce a genuinely quantum framework in order to discover causal structure remains an open question. Here we introduce a new framework for quantum causal modelling that allows for the discovery of causal structure. We define quantum analogues for core features of classical causal modelling techniques, including (...) the causal Markov condition and faithfulness. Based on the process matrix formalism, this framework naturally extends to generalised structures with indefinite causal order. (shrink)

Pearl and Woodward are both well-known advocates of interventionist causation. What is less well-known is the interesting relationship between their respective accounts. In this paper we discuss the different perspectives of causation these two accounts present and show that they are two sides of the same coin. Pearl’s focus is on leveraging global network constraints to correctly identify local causal relations. The rules by which global causal structures are composed from distinct causal relations are precisely defined by the global constraints. (...) Woodward’s focus, however, is on the use of local manipulation to identify single causal relations that then compose into global causal structures. The rules by which this composition takes place emerge as a result of local interventionist constraints. We contend that the complete picture of causality to be found between these two perspectives from the interventionist tradition must recognise both the global constraints of the sort identified by Pearl and the local constraints of the sort identified by Woodward, and the interplay between them: Pearl requires the possibility of local interventions and Woodward requires a global statistical framework within which to build composite causal structures.

It is the prevailing paradigm in contemporary physics to model the dynamical evolution of physical systems in terms of a real parameter conventionally denoted as 't' ('little tee'). We typically call such dynamical models laws of nature' and t we call 'physical time'. It is common in the philosophy of time to regard t as time itself, and to take the global structure of general relativity as the ultimate guide to physical time, and so consequently the true nature of time. (...) In this paper we defend the idea that physical time, t, is rather better defined as an operational modelling parameter: we measure relations between changing physical quantities using bespoke physical systems---i.e. clocks---that coordinate local coincidences. We argue that the sorts of physical systems that make good clocks---what we call precision clocks---are those that exhibit self-sustained oscillations known as limit cycles, which are ubiquitous in open, driven, stable, dissipative systems. We develop the physical and philosophical ramifications of this conception of physical time, particularly the notion that physical time does not track something 'out there' in the world. As a result, we speculate that physical time is perhaps not as different from manifest time as many philosophers of time (and apparently general relativity) seem to suggest. (shrink)

Linear mixed-effect models (LMMs) are being increasingly widely used in psychology to analyse multi-level research designs. This feature allows LMMs to address some of the problems identified by Speelman and McGann ( 2013 ) about the use of mean data, because they do not average across individual responses. However, recent guidelines for using LMM to analyse skewed reaction time (RT) data collected in many cognitive psychological studies recommend the application of non-linear transformations to satisfy assumptions of normality. Uncritical adoption of (...) this recommendation has important theoretical implications which can yield misleading conclusions. For example, Balota et al. ( 2013 ) showed that analyses of raw RT produced additive effects of word frequency and stimulus quality on word identification, which conflicted with the interactive effects observed in analyses of transformed RT. Generalized linear mixed-effect models (GLMM) provide a solution to this problem by satisfying normality assumptions without the need for transformation. This allows differences between individuals to be properly assessed, using the metric most appropriate to the researcher's theoretical context. We outline the major theoretical decisions involved in specifying a GLMM, and illustrate them by reanalysing Balota et al.'s datasets. We then consider the broader benefits of using GLMM to investigate individual differences. (shrink)

ABSTRACT:We combine prior research on ethical decision-making in organizations with a rational choice theory of corporate crime from criminology to develop a model of corporate offending that is tested with a sample of U.S. managers. Despite demands for increased sanctioning of corporate offenders, we find that the threat of legal action does not directly affect the likelihood of misconduct. Managers’ evaluations of the ethics of the act, measured using a multidimensional ethics scale, have a significant effect, as do outcome expectancies (...) that result from being associated with the misconduct but not facing formal sanctions. The threat of formal sanctions appears to operate indirectly, influencing ethical evaluations and outcome expectancies. Obedience to authority also affects illegal intentions, with managers reporting higher prospective offending when they are ordered to engage in misconduct by a supervisor. (shrink)

How do Dutch people let each other know that they disagree? What do they say when they want to resolve their difference of opinion by way of an argumentative discussion? In what way do they convey that they are convinced by each other’s argumentation? How do they criticize each other’s argumentative moves? Which words and expressions do they use in these endeavors? By answering these questions this short essay provides a brief inventory of the language of argumentation in Dutch.

With the advent of legalized medical assistance in dying [MAiD] in Canada in 2016, nursing is facing intriguing new ethical and theoretical challenges. Among them is the concept of conscientious objection, which was built into the legislation as a safeguard to protect the rights of healthcare workers who feel they cannot participate in something that feels morally or ethically wrong. In this paper, we consider the ethical complexity that characterizes nurses' participation in MAiD and propose strategies to support nurses' moral (...) reflection and imagination as they seek to make sense of their decision to participate or not. Deconstructing the multiple and sometimes conflicting ethical and professional obligations inherent in nursing in such a context, we consider ways in which nurses can sustain their role as critically reflective moral agents within a context of a relational practice, serving the diverse needs of patients, families, and communities, as Canadian society continues to evolve within this new way of engaging with matters of living and dying.

“Female sexual dysfunction” is the type of contested disease that has sparked concern about the role of the pharmaceutical industry in medical science. Many policies have been proposed to manage industry influence without carefully evaluating whether the proposed policies would be successful. We consider a proposal for incorporating citizen stakeholders into scientific research and show, via a detailed case study of the pharmaceutical regulation of flibanserin, that such programs can be co-opted. In closing, we use Holman’s asymmetric arms race framework (...) as a tool for evaluating policies in industry-funded science. (shrink)

This article explores how neutralisation can explain people's lack of commitment to buying Fair Trade products, even when they identify FT as an ethical concern. It examines the theoretical tenets of neutralisation theory and critically assesses its applicability to the purchase of FT products. Exploratory research provides illustrative examples of neutralisation techniques being used in the FT consumer context. A conceptual framework and research propositions delineate the role of neutralisation in explaining the attitude-behaviour discrepancies evident in relation to consumers' FT (...) purchase behaviour, providing direction for further research that will generate new knowledge of consumers' FT purchase behaviour and other aspects of ethical consumer behaviour.

:This article considers recent ethical topics relating to medical AI. After a general discussion of recent medical AI innovations, and a more analytic look at related ethical issues such as data privacy, physician dependency on poorly understood AI helpware, bias in data used to create algorithms post-GDPR, and changes to the patient–physician relationship, the article examines the issue of so-called robot doctors. Whereas the so-called democratization of healthcare due to health wearables and increased access to medical information might suggest a (...) positive shift in the patient-physician relationship, the physician’s ‘need to care’ might be irreplaceable, and robot healthcare workers might be seen as contributing to dehumanized healthcare practices.

This study identified and compared the attitudes of visitors toward zoo-housed little penguins, their enclosure and visitor experience that may influence the way visitors behave toward little penguins at two Australian zoos. Visitor attitudes were assessed using an anonymous questionnaire, targeting visitor beliefs, and experiences, where visitors were randomly approached at the penguin exhibit after they had finished viewing the penguins. Visitors were given two options to complete the questionnaire, on an iPad during their zoo visit or online (URL sent (...) via email) after their zoo visit. A total of 638 participants (495 at Melbourne Zoo and 143 at Taronga Zoo) completed the questionnaire, 42% were completed onsite during their zoo visit and 58% were completed online after their zoo visit. Most participants were living in Australia, non-zoo members, female, previously or currently owned a pet, aged between 26 and 35 years and had a University degree. Results showed that the attitude dimensions of visitors were consistent between the two zoos which indicates that these measures of attitudes were stable over time and location. Overall, visitors at both zoos had positive attitudes toward little penguins, penguin welfare, the enclosure, and visitor experience. However, whether these positive attitudes and positive visitor experience influenced the way visitors behaved toward the penguins remains unclear. There were some differences in visitor attitudes toward the perceived “aggressiveness” and “timidness” of little penguins, “negative penguin welfare”, “experience with the penguins”, “learning”, “visual barriers” and the way visitors rated their overall experience at the penguin enclosure. While the reasons for the differences in visitor attitudes and visitor experience between the zoos were not clear, some factors such as penguin behavior and enclosure design, may have been attributable to these differences. Also, a relationship was found between visitor attitudes and how visitors rated the welfare of penguins, the enclosure and visitor experience at the enclosure; more positive visitor attitudes were associated with higher ratings of penguin welfare, the enclosure and visitor experience. The practical implications of these results for zoos is unclear because the differences in visitor attitudes were numerically small. This requires further comparisons between zoos or enclosures that are more markedly different than the penguin enclosures in the present study and further research on how visitors assess zoo animals, enclosures and visitor experience.

We recognize a paradox of power and promise in the context of legislative and organizational changes in nurse regulation which poses constraints on nursing's capacity to bring voice and influence to pressing matters of healthcare and public policy. The profession is at an important crossroads wherein leaders must be well informed in political, economic and legislative trends to harness the profession's power while also navigating forces that may put at risk its central mission to serve society. We present a critical (...) policy analysis of the impact of recent regulatory trends on what the International Council of Nurses considers nursing's three ‘pillars’ – the profession of nursing, socioeconomic welfare of nurses and nurse regulation. Themes surfacing from this analysis include regulatory discontinuity, a tightening of regulatory control, and an increasingly managerial governance culture. These themes illuminate insights and strategies required to renew and revitalize the social mandate of our profession amidst a climate of urgency in the questioning of nurse scholars with respect to the future of the profession. At this historic juncture, nurses must clearly understand the implications of legislative and organizational regulatory changes to ensure the profession contributes to full capacity in achieving health and health equity globally.

Under multistakeholderism, private philanthropic foundations have played an increasingly influential role in global development. As part of which, foundations have promoted what we call “privatization creep” (i.e., mainstreaming market-centric solutions to development). Sidelining redistributive approaches altogether, “privatization creep” favours profit-making over everything else, doing little to “save the world.”.

For Ordinary Language philosophy, at issue is the use of the expressions of language, not expressions in and of themselves. So, at issue is not, for example, ordinary versus (say) technical words; nor is it a distinction based on the language used in various areas of discourse, for example academic, technical, scientific, or lay, slang or street discourses – ordinary uses of language occur in all discourses. It is sometimes the case that an expression has distinct uses within distinct discourses, (...) for example, the expression ‘empty space’. This may have both a lay and a scientific use, and both uses may count as ordinary; as long as it is quite clear which discourse is in play, and thus which of the distinct uses of the expression is in play. Though connected, the difference in use of the expression in different discourses signals a difference in the sense with which it is used, on the Ordinary Language view. One use, say the use in physics, in which it refers to a vacuum, is distinct from its lay use, in which it refers rather more flexibly to, say, a room with no objects in it, or an expanse of land with no buildings or trees. However, on this view, one sense of the expression, though more precise than the other, would not do as a replacement of the other term; for the lay use of the term is perfectly adequate for the uses it is put to, and the meaning of the term in physics would not allow speakers to express what they mean in these other contexts.

Canadian nursing practice has been profoundly influenced by the legalization of medical assistance in dying in 2016, requiring that nurses navigate new and sometimes highly challenging experiences. Findings from our longitudinal studies of nurses' experiences suggest that these include deep emotional responses to medical assistance in dying, an urgency in orchestrating the perfect death, and a high degree of relational impact, both professionally and personally. Here we propose a theoretical explanation for these experiences based upon a relational ontology. Drawing upon (...) the work of Wildman, we understand a relational ontology to be one in which relationships are more fundamentally central than the conceptual entities that provide the context to practice. It is in a relationship that conceptual entities, and their affiliated values, are created and recreated. Seen as causal, relationships have ontological status, with important implications for how we consider the concepts of death, suffering, and time in this context. From a conceptual perspective, suffering is primarily self‐defined based upon personal histories, time reflects the potential remaining until death, and death is primarily biological and amoral, although social discourses of a good and bad death surround the death trajectory. However, within a relational ontology of medical assistance in dying, these understandings shift. Death becomes primarily social rather than biological, suffering is shared, and time until death is now clearly delimited. Accordingly, nurses assume a profound responsibility for influencing outcomes that are authentically person‐centered. These understandings provide important insights into nurses' experiences, enabling us to recognize the causal effects, both intended and unintended, of nurses' relational practices amidst the complexities of assisted death. Drawing on such a perspective, we find implications for how we provide spaces for nurses to reflect on, and have conversations about, their experiences with some of the greatest mysteries of life—death, suffering, and time.

There has been considerable interest in the literature about how professions operate in both the private and public interest. This paper examines this issue in the context of the enforcement of the professional code of conduct of a particular professional accounting association. The paper explores whether certain enforcement actions of the association suggest behaviour motivated at least partially by private interest. It then considers whether the consequences of such behaviour or practices are troubling.

Drawing on Connell's notion of gender projects, the authors assess the degree to which contemporary evangelical ideals of men's headship challenge, as well as reinforce, a hegemonic masculinity. Based on 265 in-depth interviews in 23 states across the country, they find that rather than espousing a traditional gender hierarchy in which women are simply subordinate to men, the majority of contemporary evangelicals hold to symbolic traditionalism and pragmatic egalitarianism. Symbolic male headship provides an ideological tool with which individual evangelicals may (...) maintain a sense of distinctiveness from the broader culture of which they are a part. At the same time, symbolic headship blunts some of the harsher effects of living in a materially rich, but time poor, culture, by defusing an area of potential conflict, creating a safe space within which men can negotiate, and strengthening men's material and emotional ties to their families.

Influences on the perception of affordances (i.e., opportunities for actions) have been primarily studied by manipulating the functional morphology of the body. However, affordances are not just determined by the functional morphology of the perceiver, but also by the physiological state of the perceiver. States of anxiety have been shown to lead to marked changes in individuals’ physiological state and their behaviour. To assess the influence of emotional state on affordance perception, the perception of action capabilities in near space was (...) examined after participants completed an anxiety-provoking task. Anxiety was induced immediately prior to tasks that assessed participants' perceived reaching ability in Experiment 1, grasping ability in Experiment 2, and the ability to pass their hands through apertures in Experiment 3. Results indicated that those participants who experienced changes in anxiety underestimated their reaching, grasping, and passing ability compared to non-anxious participants. In other words, anxious participants were more conservative in their estimations of their action capabilities. These results suggest that anxiety influences the perception for affordances in near space and are consistent with the notion that anxiety induces withdrawal behaviours. (shrink)

The notion of social capital focuses attention on social connectedness within communities and the ways that this connectedness may affect health and well-being. There are many competing definitions of social capital but most suggest that it involves trust, social networks and reciprocity within communities, not necessarily geographically defined. The usefulness of social capital and related theories that help in understanding the function of nurses in rural communities are explored in this paper. Nurses and health service planners are becoming increasingly aware (...) of the potential contribution of community nurses in rural and/or remote areas, as evidenced in the development of nurse practitioners. Through their interrelational role and status in rural communities, nurses are often ‘immersed’ or ‘embedded’ in the social networks that make up the fabric of rural life and may therefore be important contributors to social capital. For a concept such as social capital to be useful in nursing research, it must have distinct attributes, delineated boundaries, and well-described preconditions and outcomes in multiple contexts.

This article introduces the special issue on middle-range theory in science and technology studies, providing the background to its production and reviewing different notions of “middle.” It begins with Merton's ideas about middle-range theory as a way of moving beyond the production of either descriptions or theories of everything. Instead of seeing the middle as the space between the theoretical imagination and the detailed depiction of everyday practices, the authors outline three ways of thinking about the middle range: as an (...) adjective, the closest to Merton's conception; as a noun, the liminal place between theories, audiences, and levels; and as a verb, a process, a means of making connections across time, discipline, community, and place. A summary of each of the articles in this special issue is provided, preceding a call for further discussion about the role of case studies and the nature of the middle in STS. (shrink)

BackgroundMoral distress (MD) is an emotional and psychological response to morally challenging dilemmas. Moral distress is experienced frequently by nurses in the intensive care unit (ICU) and can result in emotional anguish, work dissatisfaction, poor patient outcomes, and high levels of nurse turnover. Opportunities to discuss ethically challenging situations may lessen MD and its associated sequela.ObjectiveThe purpose of this project was to develop, implement, and evaluate the impact of nursing ethics huddles on participants’ MD, clinical ethics knowledge, work satisfaction, and (...) patient care among ICU nurses.Sample and SettingThe sample, 32 nurses from three ICU settings in an 800-bed tertiary academic medical center, participated in six nursing ethics huddles over a two-month period.MethodsAlvita K. Nathaniel’s Theory of Moral Reckoning guided development of the nursing ethics huddle process.1 The Moral Distress Thermometer was administered at three data points: baseline level of MD, and pre- and post-huddle to determine changes in the subjects’ level of MD.2 Focused content analysis was used to analyze qualitative responses from questionnaires about the subjects’ perception of the effect of the huddles on work satisfaction and patient care. Knowledge attainment was evaluated via open-ended short-answer questions.ResultsOverall, use of nurse-ethicist-led nursing ethics huddles was associated with improved quality of work life, patient care, and clinical ethics knowledge. The change in pre- and post-nursing ethics huddles MD scores was statistically significant (p < 0.0001). (shrink)

What's wrong with high executive pay? Beyond envy, is some issue of justice or fairness at stake? And what can anyone do about it? (A lot, as it turns out.).

"What is sexist oppression?" "What should be done about it?" Organized around these questions, Theorizing Feminisms: A Reader provides an overview of theoretical feminist writing about the quest for gender justice. Incorporating both classic and cutting-edge material, the reader takes into account the full diversity of women, highlighting the effects of race, ethnicity, nationality, class, sexuality, and religion on women's experience. Theorizing Feminisms is organized into four sections and includes fifty-four essays. The first section introduces several basic concepts commonly employed (...) when thinking about sexism--oppression, social construction, essentialism, intersectionality, gender, race, and class--and also raises questions about the perspective and legitimacy of the theorist. The second section surveys three approaches that attempt to characterize in a general way the source of injustice toward women: humanist feminism ("the sameness approach"), gynocentric feminism ("the difference approach"), and dominance feminism. Offering an alternate perspective, the third section introduces two "localizing" approaches, grounded in postmodernism and identity politics, respectively. Skeptical of theories that attempt to analyze social phenomena across history and culture, authors in this section challenge, rather than answer, the text's organizing questions. The final section explores the relationship of feminist theory to three liberatory projects--postcolonialism, neo-materialism, and queer theory--that do not characterize themselves as feminist, yet take gender as a significant category of analysis. Each section opens with an introduction and each essay is followed by helpful study questions. The majority of the essays are presented in their entirety. Theorizing Feminisms underscores the strong connection between feminist theory and practice by including essays that illustrate important political inspirations or applications of each theoretical approach. It also presents versions of the same approach from various points in history, revealing feminist theory to be dynamic and evolving, rather than static. Ideal for interdisciplinary courses in feminist theory, this volume will also serve as an invaluable reference for current and future generations of theorists. (shrink)

This paper draws on classical theories of wisdom to explore the organisational impact of nurses on Australian general practice. Between 2004 and 2008, numbers of general practice nurses doubled, the most rapid influx of nurses into any Australian workplace over the decade. Using data from the Australian General Practice Nurses Study, we argue that nurses had a positive impact because they introduced techne at the organisational level and amplified phronesis in clinical activities. In its Hippocratic formulation, techne refers to a (...) field of definable knowledge, which is purposeful and useful and requires mastery of rational principles. Nursing, with its focus on system and accountability, brought techne out of the GP’s consulting room and into the general practice as a whole. Nurses also exemplify phronesis, an Aristotelian virtue connoting a reasoned and honourable capacity to make judgements: the practical wisdom that defines the interaction between clinician and patient in general practice. At a time of significant GP shortage, doctors and nurses began to collaborate around their more complex and time-consuming patients, leading to a deepening of phronesis in the workplace. By bringing techne to bear on the organisation, and complementing and enhancing phronesis, nurses propel organisational wisdom in general practices. (shrink)

Under current UK law, an embryo cannot be transferred to a woman's uterus without the consent of both of its genetic parents, that is both of the people from whose gametes the embryo was created. This consent can be withdrawn at any time before the embryo transfer procedure. Withdrawal of consent by one genetic parent can result in the other genetic parent losing the opportunity to have their own genetic children. We argue that offering couples only one type of consent (...) agreement, as happens at present, is too restrictive. An alternative form of agreement, in which one genetic parent agrees to forego the right to future withdrawal of consent, should be available alongside the current form of agreement. Giving couples such a choice will better enable them to store embryos under a consent agreement that is appropriate for their circumstances. Allowing such a choice, with robust procedures in place to ensure the validity of consent, is the best way to respect patient autonomy. (shrink)

Since 1991, sperm donors in the UK have had the legal right to withdraw consent for the use of their sperm in fertility treatment. This has the potential to adversely affect patients. It may mean that previous recipients of a donor’s sperm cannot have further children who are full biological siblings to an existing child, and that embryos created from the donor’s sperm and a patient’s eggs must be destroyed.
