Theories of the genetics underlying punctuated equilibrium (PE) have been vague to date. Here the developmental gene hypothesis is proposed, which states that: 1) developmental regulatory (DevReg) genes are responsible for the orchestration of metazoan morphogenesis and their extreme conservation and mutation intolerance generates the equilibrium or stasis present throughout much of the fossil record and 2) the accumulation of regulatory elements and recombination within these same genes—often derived from transposable elements—drives punctuated bursts of morphological divergence and speciation across metazoa. (...) This two‐part hypothesis helps to explain the features that characterize PE, providing a theoretical genetic basis for the once‐controversial theory.

This study examines the socioeconomic and familial background of Irish Catholic priests born between 1867 and 1911. Previous research has hypothesized that lack of marriage opportunities may influence adoption of celibacy as part of a religious institution. The present study traced data from Irish seminary registries for 46 Catholic priests born in County Limerick, Ireland, using 1901 Irish Census returns and Land Valuation records. Priests were more likely to originate from landholding backgrounds, and with landholdings greater in size and wealth (...) than the local average. Priests were found to originate from families with more sons than the national average, but with similar numbers of daughters. These findings are discussed in relation to competition for resources and lineage survival strategies. (shrink)

BackgroundFreezing of gait is a disabling burden for Parkinson’s disease patients with poor response to conventional therapies. Combined deep brain stimulation of the subthalamic nucleus and substantia nigra moved into focus as a potential therapeutic option to treat the parkinsonian gait disorder and refractory FoG. The mechanisms of action of DBS within the cortical-subcortical-basal ganglia network on gait, particularly at the cortical level, remain unclear.MethodsTwelve patients with idiopathic PD and chronically-implanted DBS electrodes were assessed on their regular dopaminergic medication in (...) a standardized stepping in place paradigm. Patients executed the task with DBS switched off, conventional STN DBS and combined STN+SN DBS and were compared to healthy matched controls. Simultaneous high-density EEG and kinematic measurements were recorded during resting-state, effective stepping, and freezing episodes.ResultsClinically, STN+SN DBS was superior to conventional STN DBS in improving temporal stepping variability of the more affected leg. During resting-state and effective stepping, the cortical activity of PD patients in STIM OFF was characterized by excessive over-synchronization in the theta, alpha, and high-beta band compared to healthy controls. Both active DBS settings similarly decreased resting-state alpha power and reduced pathologically enhanced high-beta activity during resting-state and effective stepping compared to STIM OFF. Freezing episodes during STN DBS and STN+SN DBS showed spectrally and spatially distinct cortical activity patterns when compared to effective stepping. During STN DBS, FoG was associated with an increase in cortical alpha and low-beta activity over central cortical areas, while with STN+SN DBS, an increase in high-beta was prominent over more frontal areas.ConclusionsSTN+SN DBS improved temporal aspects of parkinsonian gait impairment compared to conventional STN DBS and differentially affected cortical oscillatory patterns during regular locomotion and freezing suggesting a potential modulatory effect on dysfunctional cortical-subcortical communication in PD.

The number of children with chronic critical illness (CCI) is a growing population in the United States. A defining characteristic of this population is a prolonged hospital stay. Our study assessed the proportion of pediatric patients with chronic critical illness in U.S. hospitals at a specific point in time, and identified a subset of children whose hospital stay lasted for months to years. The potential harms of a prolonged hospitalization for children with CCI, which include over treatment, infection, disruption of (...) family life, and the intensive utilization of resources—combined with the moral distress experienced by the clinicians who care for the children, suggest the need for ethical analysis of this growing issue to identify actions that could be taken at the clinical and health systems levels to reduce the harms associated with prolonged hospital stay.In this article we present three real cases from our study that involved a very long hospital stay. We applied a framework developed by Mackenzie, Rogers, and Dodds to analyze inherent, situational, and pathogenic vulnerabilities to examine the ways that interventions intended to remedy one source of harm for the children in our cohort inadvertently created other harms. We examined the complex ways that children with protracted hospitalization are vulnerable to the choices made by their family and clinicians, as well as by healthcare systems and communities. Finally, we used this analysis to summarize actions and ethical responses to this growing patient population. Such an understanding is essential to making clinical and ethical decisions that arise for children who are at risk for a very long stay in the hospital. (shrink)

BackgroundThe preferable position of Deep Brain Stimulation electrodes is proposed to be located in the dorsolateral subthalamic nucleus to improve general motor performance. The optimal DBS electrode localization for the post-operative improvement of balance and gait is unknown.MethodsIn this single-center, retrospective analyses, 66 Parkinson’s disease patients were assessed pre- and post-operatively by using MDS-UPDRS, freezing of gait score, Giladi’s gait and falls questionnaire and Berg balance scale. The clinical outcome was related to the DBS electrode coordinates in x, y, z (...) plane as revealed by image-based reconstruction. Binomial generalized linear mixed models with fixed-effect variables electrode asymmetry, parkinsonian subtype, medication, age class and clinical DBS induced changes were analyzed.ResultsSubthalamic nucleus-deep brain stimulation improved all motor, balance and FoG scores in MED OFF condition, however there were heterogeneous results in MED ON condition. DBS electrode reconstructed coordinates impacted the responsiveness of axial symptoms. FoG and balance responders showed slightly more medially located STN electrode coordinates and less medio-lateral asymmetry of the electrode reconstructed coordinates across hemispheres compared to non-responders.ConclusionDeep brain stimulation electrode reconstructed coordinates, particularly electrode asymmetry on the medio-lateral axis affected the post-operative responsiveness of balance and FoG symptoms in PD patients.

In this paper, we introduce the notion of $${\textbf{K}} $$ -rank, where $${\textbf{K}} $$ is a strong amalgamation Fraïssé class. Roughly speaking, the $${\textbf{K}} $$ -rank of a partial type is the number “copies” of $${\textbf{K}} $$ that can be “independently coded” inside of the type. We study $${\textbf{K}} $$ -rank for specific examples of $${\textbf{K}} $$, including linear orders, equivalence relations, and graphs. We discuss the relationship of $${\textbf{K}} $$ -rank to other ranks in model theory, including dp-rank and (...) op-dimension (a notion coined by the first author and C. D. Hill in previous work).

This paper focuses on the integration of generic software such as enterprise resource planning into organisational life. These applications have gained prominence as the IT systems of choice in many organisations. The perspective that dominates the literature studying these applications reflects a rationality based on alignment of the software and organisational processes and fails to consider the ethical issues that arise when a new work system is being constructed, such as the possibilities for end‐user participation. Drawing on the strand of (...) research that studies implementations of new technologies as social relations, this paper considers the experiences of end user groups as they engage in adaptation of the software and embed technology in contexts of local use. Design and use activities are complex and multifaceted and the embedding of software for local use represents an overlap between them. This paper explores whether the shift towards large scale generic software allows for a blurring of a boundary between what are construed as design activities and use activities in applications for office work. It is significant to the construction of this boundary that office work is gendered female in the U.K. where clerical and secretarial work is usually done by and considered to be suited to women. The paper draws on a case study of the introduction and integration of a generic software application for supporting the administration of student records at a UK university to explore the social relations of end‐user participation in the implementation of these software packages. The paper presents an analysis of the implementation activity, IToffice worker relations, and the different constructions of skills and knowledge understood to be required as the workers attempted to deal with this software application.

We present the first systematic literature review on stress and burnout in K−12 teachers during the COVID-19 pandemic. Based on a systematic literature search, we identified 17 studies that included 9,874 K−12 teachers from around the world. These studies showed some indication that burnout did increase during the COVID-19 pandemic. There were, however, almost no differences in the levels of stress and burnout experienced by K−12 teachers compared to individuals employed in other occupational fields. School principals' leadership styles emerged as (...) an organizational characteristic that is highly relevant for K−12 teachers' levels of stress and burnout. Individual teacher characteristics associated with burnout were K−12 teachers' personality, self-efficacy in online teaching, and perceived vulnerability to COVID-19. In order to reduce stress, there was an indication that stress-management training in combination with training in technology use for teaching may be superior to stress-management training alone. Future research needs to adopt more longitudinal designs and examine the interplay between individual and organizational characteristics in the development of teacher stress and burnout during the COVID-19 pandemic and beyond.

I examine a number of recent challenges to traditional individualist epistemologies. In chapter I, I examine Margaret Gilbert's claim that certain types of communities, "plural subjects," are capable of having what she calls "collective beliefs." In chapter II, I examine Lynn Hankinson Nelson's claim that communities, and not individuals, are the primary epistemological agents. In chapter III, I examine Miriam Solomon's claim that scientific rationality is a property of communities, not individuals. In chapter IV, I examine Richard Rorty's claim (...) that solidarity is the end of inquiry. Finally, in chapter V, I examine Helen Longino's claim that scientific knowledge and inquiry are mediated by processes that are irreducibly social. ;I argue that many philosophers who argue for a more social epistemology are mistaken about what role the community plays in inquiry, and that only individuals are epistemic agents--only they believe, know, and act rationally. In this respect, traditional individualist epistemologies are correct. I also argue that what is distinctively and irreducibly social about inquiry are the norms and processes that mediate our interaction with each other. These norms and processes require numerous individuals to sustain them. Further, I argue that given this understanding of the role of the community in inquiry we are required to change our understanding of both the nature and role of the individual knower, and the project of epistemology. Individual knowers are dynamic, changing their conception of themselves as they interact in the world with others. An integral but hitherto neglected part of epistemology is the evaluation of the social processes that mediate our interaction with others. (shrink)

I critically examine Miriam Solomon’s critique of individualist normative accounts of scientific rationality and her own “social” account of scientific rationality that takes communities to be the locus of rationality. I argue that scientists are not influenced in their decision making by nonepistemic factors to the extent that Solomon suggests and an individualist account can show how judgmental heuristics are conducive to scientific success. I also argue that Solomon’s account of rationality cannot guide us when we do not yet (...) know what is most conducive to scientific success. Consequently, I offer a defense of internalist individualist accounts of rationality and suggest that what is social about rationality are the standards of epistemic responsibility. (shrink)

Cognitive science is experiencing a pragmatic turn away from the traditional representation-centered framework toward a view that focuses on understanding cognition as "enactive." This enactive view holds that cognition does not produce models of the world but rather subserves action as it is grounded in sensorimotor skills. In this volume, experts from cognitive science, neuroscience, psychology, robotics, and philosophy of mind assess the foundations and implications of a novel action-oriented view of cognition. Their contributions and supporting experimental evidence show that (...) an enactive approach to cognitive science enables strong conceptual advances, and the chapters explore key concepts for this new model of cognition. The contributors discuss the implications of an enactive approach for cognitive development; action-oriented models of cognitive processing; action-oriented understandings of consciousness and experience; and the accompanying paradigm shifts in the fields of philosophy, brain science, robotics, and psychology.

In this paper, I begin by defending permissivism: the claim that, sometimes, there is more than one way to rationally respond to a given body of evidence. Then I argue that, if we accept permissivism, certain worries that arise as a result of learning that our beliefs were caused by the communities we grew up in, the schools we went to, or other irrelevant influences dissipate. The basic strategy is as follows: First, I try to pinpoint what makes irrelevant influences (...) worrying and I come up with two candidate principles. I then argue that one principle should be rejected because it is inconsistent with permissivism. The principle we should accept implies that it is sometimes rational to maintain our beliefs, even upon learning that they were caused by irrelevant influences. (shrink)

The Queen's College, Oxford, UK In his article `Facts and Principles', G.A. Cohen attempts to refute constructivist approaches to justification by showing that, contrary to what their proponents claim, fundamental normative principles are fact- in sensitive. We argue that Cohen's `fact-insensitivity thesis' does not provide a successful refutation of constructivism because it pertains to an area of meta-ethics which differs from the one tackled by constructivists. While Cohen's thesis concerns the logical structure of normative principles, constructivists ask how normative principles (...) should be justified . In particular, their claim that justified fundamental normative principles are fact-sensitive follows from a commitment to agnosticism about the existence of objective moral facts. We therefore conclude that, in order to refute constructivism, Cohen would have to address questions of justification, and take a stand on those long-standing meta-ethical debates about the ontological status of moral notions (for example, realism versus anti-realism) with respect to which he himself wants to remain agnostic. Key Words: John Rawls • normative justification • realism versus anti-realism • methodological versus substantive principles. (shrink)

The revival of recognition theory has brought new energy to critical theory. In general terms, recognition theory aims to critically evaluate social structures against a standard of social freedom identified with norms of interaction which are freely recognized by all parties. Until now, attention has primarily focused on the categories and forms of recognition theory. However, the influence of contemporary French theory upon the development of theories of recognition has not yet received the consideration it merits. The book takes up (...) this task. With chapters by internationally recognized authors, the collection outlines the current state of recognition theory, studies the impact of French theory, and uses French thought to identity aspects of the recognitive process which are often overlooked. Exploring French accounts of agonistic identity construction, vulnerability, power, ethical obligation, and reflexive theory construction, this book supports the intentions of critical theory with heightened attentiveness to oppression in all of its forms.

From the Ancient Greeks, through medieval Christian doctrine, and into the modern age, philosophers have long held envy to be irrational, a position that increasingly accompanies the political view that envy is not a justification for redistributing material goods. After defining the features of envy, and considering two arguments in favour of its irrationality, this article opposes the dominant philosophical and political consensus. It does so by deploying Rawls's much-ignored concept of ‘excusable envy’ to identify a form of envy that (...) is not imprudent and does not mis-describe. With this work completed, the article then argues – no doubt controversially – that excusable envy constitutes good grounds for redistribution or inequality-mitigation. In so doing, the article throws light on the moral significance of certain forms of uncivil disobedience, and also offers a new vocabulary for popular ‘politics of envy’ debates, which are yet to acknowledge the role of social institutions in reproducing envy-excusing economic inequalities.

This paper is about the connection between rationality and accuracy. I show that one natural picture about how rationality and accuracy are connected emerges if we assume that rational agents are rationally omniscient. I then develop an alternative picture that allows us to relax this assumption, in order to accommodate certain views about higher order evidence.

Greaves and Wallace argue that conditionalization maximizes expected accuracy. In this paper I show that their result only applies to a restricted range of cases. I then show that the update procedure that maximizes expected accuracy in general is one in which, upon learning P, we conditionalize, not on P, but on the proposition that we learned P. After proving this result, I provide further generalizations and show that much of the accuracy-first epistemology program is committed to KK-like iteration principles (...) and to the existence of a class of propositions that rational agents will be certain of if and only if they are true.

In recent years, permissivism—the claim that a body of evidence can rationalize more than one response—has enjoyed somewhat of a revival. But it is once again being threatened, this time by a host of new and interesting arguments that, at their core, are challenging the permissivist to explain why rationality matters. A version of the challenge that I am especially interested in is this: if permissivism is true, why should we expect the rational credences to be more accurate than the (...) irrational ones? My aim is to turn this challenge on its head and argue that, actually, those who deny permissivism will have a harder time responding to such a challenge than those who accept it. (shrink)

The aim of this paper is to apply the accuracy based approach to epistemology to the case of higher order evidence: evidence that bears on the rationality of one's beliefs. I proceed in two stages. First, I show that the accuracy based framework that is standardly used to motivate rational requirements supports steadfastness—a position according to which higher order evidence should have no impact on one's doxastic attitudes towards first order propositions. The argument for this will require a generalization of (...) an important result by Greaves and Wallace for the claim that conditionalization maximizes expected accuracy. The generalization I provide will, among other things, allow us to apply the result to cases of self-locating evidence. In the second stage, I develop an alternative framework. Very roughly, what distinguishes the traditional approach from the alternative one is that, on the traditional picture, we're interested in evaluating the expected accuracy of conforming to an update procedure. On the alternative picture that I develop, instead of considering how good an update procedure is as a plan to conform to, we consider how good it is as a plan to make. I show how, given the use of strictly proper scoring rules, the alternative picture vindicates calibrationism: a view according to which higher order evidence should have a significant impact on our beliefs. I conclude with some thoughts about why higher order evidence poses a serious challenge for standard ways of thinking about rationality. (shrink)

The question of whether it is ever permissible to believe on insufficient evidence has once again become a live question. Greater attention is now being paid to practical dimensions of belief, namely issues related to epistemic virtue, doxastic responsibility, and voluntarism. In this book, McCormick argues that the standards used to evaluate beliefs are not isolated from other evaluative domains. The ultimate criteria for assessing beliefs are the same as those for assessing action because beliefs and actions are both products (...) of agency. Two important implications of this thesis, both of which deviate from the dominant view in contemporary philosophy, are 1) it can be permissible to believe for non-evidential reasons, and 2) we have a robust control over many of our beliefs, a control sufficient to ground attributions of responsibility for belief.

This article summarizes a virtual live‐streamed panel event that occurred in August 2020 and was cosponsored by the International Philosophy of Nursing Society (IPONS) and the University of California, Irvine's Center for Nursing Philosophy. The event consisted of a series of three self‐contained panel discussions focusing on the past, present and future of IPONS and was moderated by the current Chair of IPONS, Catherine Green. The first panel discussion explored the history of IPONS and the journal Nursing Philosophy. The second (...) panel involved a reflection on the challenges of doing nursing philosophy in a research‐intensive context of a Canadian university and the history and current movements in nursing philosophy in the Nordic countries. The final panel involved presentations on the future potential for philosophy in/and for nursing, the critical connections between nursing philosophy and nursing theory, dismantling racism in nursing and the potential for process philosophy to help explore nursing's unique efficacy in creating possibilities for health. The panels were followed by a lively Q&A session with participants, of which there were 252 registrants from across the globe. The event underscored the wide and diverse interests of nurses in philosophical discussion and the need for more virtual events and other connective modalities bringing nurses together to discuss and analyze the value and potential of philosophy to better understand and advance nursing theory and practice.

Jacqueline Fawcett's nursing metaparadigm—the domains of person, health, environment, and nursing—remains popular in nursing curricula, despite having been repeatedly challenged as a logical philosophy of nursing. Fawcett appropriated the word “metaparadigm” (indirectly) from Margaret Masterman and Thomas Kuhn as a devise that allowed her to organize then‐current areas of nursing interest into a philosophical “hierarchy of knowledge,” and thereby claim nursing inquiry and practice as rigorously “scientific.” Scholars have consistently rejected the logic of Fawcett's metaparadigm, but have not yet proposed (...) a substantially agreed‐upon alternative. Through an analysis of articles introducing and critiquing Fawcett's metaparadigm, I argue for a re‐conceptualized metaparadigm that articulates nursing's ontology. What exists for the nursing discipline are not already‐demarcated metaparadigm domains, but rather interdependent, dynamic relations that constitute people, including nurses, in their health/environment circumstance. The nursing discipline aims to skillfully access this dynamic relationality as the basis for action and reflection to produce both positive health trajectories and knowledge that facilitates future action and reflection. Further inquiry into the onto‐epistemology of nursing will produce a more robust understanding of nursing practice, science, and philosophy, and clarify its unique contribution to health and healthcare.

Theories and models are not equivalent. I argue that an orientation towards models as a primary carrier of nursing knowledge overcomes many ongoing challenges in philosophy of nursing science, including the theory–practice divide and the paradoxical pursuit of predictive theories in a discipline that is defined by process and a commitment to the non‐reducibility of the health/care experience. Scientific models describe and explain the dynamics of specific phenomenon. This is distinct from theory, which is traditionally defined as propositions that explain (...) and/or predict the world. The philosophical case has been made against theoretical universalism, showing that a theory can be true in its domain, but that no domain is universal. Subsequently, philosophers focused on scientific models argued that they do the work of defining the boundary conditions—the domain(s)—of a theory. Further analysis has shown the ways models can be constructed and function independent of theory, meaning models can comprise distinct, autonomous “carriers of scientific knowledge.” Models are viewed as representations of the active dynamics, or mechanisms, of a phenomenon. Mechanisms are entities and activities organized such that they are productive of regular changes. Importantly, mechanisms are by definition not static: change may alter the mechanism and thereby alter or create entirely new phenomena. Orienting away from theory, and towards models, focuses scholarly activity on dynamics and change. This makes models arguably critical to nursing science, enabling the production of actionable knowledge about the dynamics of process and change in health/care. I briefly explore the implications for nursing—and health/care—knowledge and practice. (shrink)

It has been claimed that, in response to certain kinds of evidence, agents ought to adopt imprecise credences: doxastic states that are represented by sets of credence functions rather than single ones. In this paper I argue that, given some plausible constraints on accuracy measures, accuracy-centered epistemologists must reject the requirement to adopt imprecise credences. I then show that even the claim that imprecise credences are permitted is problematic for accuracy-centered epistemology. It follows that if imprecise credal states are permitted (...) or required in the cases that their defenders appeal to, then the requirements of rationality can outstrip what would be warranted by an interest in accuracy.

It seems like we care about at least two features of our credence function: gradational-accuracy and verisimilitude. Accuracy-first epistemology requires that we care about one feature of our credence function: gradational-accuracy. So if you want to be a verisimilitude-valuing accuracy-firster, you must be able to think of the value of verisimilitude as somehow built into the value of gradational-accuracy. Can this be done? In a recent article, Oddie has argued that it cannot, at least if we want the accuracy measure (...) to be proper.

The aim of this paper is to describe a problem for calibrationism: a view about higher order evidence according to which one's credences should be calibrated to one's expected degree of reliability. Calibrationism is attractive, in part, because it explains our intuitive judgments, and provides a strong motivation for certain theories about higher order evidence and peer disagreement. However, I will argue that calibrationism faces a dilemma: There are two versions of the view one might adopt. The first version, I (...) argue, has the implausible consequence that, in a wide range of cases, calibrationism is the only constraint on rational belief. The second version, in addition to having some puzzling consequences, is unmotivated. At the end of the paper I sketch a possible solution. (shrink)

A defense of imprecise credences (and other imprecise doxastic attitudes).

Abstract: This paper defends a constraint that any satisfactory decision theory must satisfy. I show how this constraint is violated by all of the decision theories that have been endorsed in the literature that are designed to deal with cases in which opinions or values are represented by a set of functions rather than a single one. Such a decision theory is necessary to account for the existence of what Ruth Chang has called “parity” (as well as for cases in (...) which agents have incomplete preferences or imprecise credences). The problem with the all of the decision theories that have been defended to account for parity is that they are committed to a claim I call unanimity: when all of the functions in the set agree that an agent ought to do A, then an agent ought to do A. A decision theory committed to unanimity violates the constraint I defend in this paper. Thus, if parity exists, a new approach to decision theory is necessary. (shrink)

Had we grown up elsewhere or been educated differently, our view of the world would likely be radically different. What to make of this? This paper takes an accuracy-centered first-personal approach to the question of how to respond to the arbitrary nature in which many of our beliefs are formed. I show how considerations of accuracy motivate different responses to this sort of information depending on the type of attitude we take towards the belief in question upon subjecting the belief (...) to doubt.
