We present a general framework for analyzing the contribution to reproductive success of a behavioural action. An action may make a direct contribution to reproductive success, but even in the absence of a direct contribution it may make an indirect contribution by changing the animal's state. We consider actions over a period of time, and define a reward function that characterizes the relationship between the animal's state at the end of the period and its future reproductive success. Working back from (...) the end of the period using dynamic programming, the optimal action as a function of state and time can be found. The procedure also yields a measure of the cost, in terms of future reproductive success, of a suboptimal action. These costs provide us with a common currency for comparing activities such as eating and drinking, or eating and hiding from predators. The costs also give an indication of the robustness of the conclusions that can be drawn from a model. We review how our framework can be used to analyze optimal foraging decisions in a stochastic environment. We also discuss the modelling of optimal daily routines and provide an illustration based on singing to attract a mate. We use the model to investigate the features that can produce a dawn song burst in birds. State is defined very broadly so that it includes the information an animal has about its environment. Thus, exploration and learning can be included within the framework. (shrink)

A general framework for analysing the effects of variability and the effects of interruptions on foraging is presented. The animal is characterised by its level of energetic reserves, x. We consider behaviour over a period of time [0,T]. A terminal reward function R(x) determines the expected future reproductive success of an animal with reserves x at time T. For any state x at a time in the period, we give the animal a choice between various options and then constrain it (...) to follow a background strategy. The best option is the one that maximizes expected future reproductive success. Using this framework, we show that sensitivity to variability in amount of energy gained is logically distinct from sensitivity to variability in the time at which food is obtained. We also show that incorporating interruptions results in both a preference for variability in time and a preference for a reward followed by a delay as opposed to the same delay before the reward.

IntroductionThe objectives of this study are to assess and compare differences in the intensity, frequency, and overall severity of moral distress among a diverse group of healthcare professionals.MethodsParticipants from within Baylor Health Care System completed an online seven-point Likert scale (range, 0 to 6) moral distress survey containing nine core clinical scenarios and additional scenarios specific to each participant’s discipline. Higher scores reflected greater intensity and/or frequency of moral distress.ResultsMore than 2,700 healthcare professionals responded to the survey (response rate 18.14 (...) percent); survey respondents represented multiple healthcare disciplines across a variety of settings in a single healthcare system. Intensity of moral distress was high in all disciplines, although the causes of highest intensity varied by discipline. Mean moral distress intensity for the nine core scenarios was higher among physicians than nurses, but the mean moral distress frequency was higher among nurses. Taking into account both intensity and frequency, the difference in mean moral distress score was statistically significant among the various disciplines. Using post hoc analysis, differences were greatest between nurses and therapists.ConclusionsMoral distress has previously been described as a phenomenon predominantly among nursing professionals. This first-of-its-kind multidisciplinary study of moral distress suggests the phenomenon is significant across multiple professional healthcare disciplines. Healthcare professionals should be sensitive to situations that create moral distress for colleagues from other disciplines. Policy makers and administrators should explore options to lessen moral distress and professional burnout that frequently accompanies it. (shrink)

Rolls discusses various adaptive explanations of physiological processes and the emotions. We give a critical analysis of some of these from the perspective of behavioural ecology. While agreeing with the approach adopted by Rolls, we identify topics that could have been better presented by making use of the existing literature.

John Maynard Smith was the founder of evolutionary game theory. He has also been the major influence on the direction of this field, which now pervades behavioural ecology and evolutionary biology. In its original formulation the theory had three components: a set of strategies, a payoff structure, and a concept of evolutionary stability. These three key components are still the basis of the theory, but what is assumed about each component is often different to the original assumptions. We review modern (...) approaches to these components. We emphasis that if a game is considered in isolation, and arbitrary payoffs are assumed, then the payoffs may not be consistent with other components of the system which are not modelled. Modelling the whole system, including not only the focal game, but also the future behaviour of the players and the behaviour of other population members, allows a consistent model to be constructed. We illustrate this in the case of two models of parental care, showing how linking a focal game to other aspects of the system alters what is predicted. (shrink)

This article is a prophetic and historical look at the prospects for spiritual direction and soul care in our contemporary setting. The thrust of this essay is to argue that soul care today needs to embrace three dimensions: the historical, the biblical, as well as the contemporary behavioral sciences. Otherwise our judgments will be imprisoned within our own culture if we have not traveled abroad in time as well as space, to understand the faith and devotion of God's people in (...) the cultures of the past. We will suggest five aspects of the history of Christian devotion that we need to “remember” today: the lives of the saints, the exercise of contrition, the memory of the Psalms, the basic use of figurative language, and the importance of letter-writing.

The ABCs of Education is a philosophy of education introducing a unique learning perspective that promotes interest based learning for the purpose of fostering authentic empowerment via civic engagement. This book begins by clarifying the function of education and the need for creating safe and welcoming learning environments by modeling altruistic practices. Altruism is justified with a that a theory that explains synergy in the context of education. The book then goes on to introduce a concept referred to as Biosintegrumology. (...) This is book is the most comprehensive introduction of Biosintegumology to date. Biosintegrumology is used to demonstrate the importance of student interest in curriculum design. Finally, the book concludes with detailing the role of civics in education. (shrink)

It is shown that in a range of models, the probability that a forager dies from starvation is, to a good approximation, an exponential function of energy reserves. Using a time and energy budget for a 19g passerine, we explore the consequences, in terms of starvation and predation, of various levels of energy reserves. It is shown that there exists an optimal level L of reserves at which total mortality (starvation plus predation) is minimized. L increases when the environment deteriorates (...) as a result of a decrease in either temperature or mean gross gain or an increase in the mean search time. The effect of combined deteriorations is greater than the sum of their individual effects. At L, the probability of predation is much higher than the probability of starvation. A simple analytic model suggests that this result will be fairly general, but also indicates conditions under which the result might not hold. (shrink)

We present a dynamic programming model which is used to investigate hypothermia as an adaptive response by small passerine birds in winter. The model predicts that there is a threshold function of reserves during the night, below which it is optimal to enter hypothermia, and above which it is optimal to rest. This threshold function decreases during the night, with a particularly sharp drop at the end of the night, representing the time and energy costs associated with returning to normal (...) body temperature. The results of the model emphasise the trade-off between energy and predation, not just between foraging options, but also between foraging during the day and entering hypothermia at night. The value of being able to use hypothermia represents not just energy savings, but also reduced predation risk due to changes in the optimal foraging strategy. Conditions which give a high value of hypothermia are short photoperiod, variable food supply, low temperatures, poor and scarce food supplies. (shrink)

One legacy of post-Enlightenment dualism in the universe of academic discourse is the presence of two approached to notions of duality championed by two differing camps. One camp might arbitrarily be called debunkers; the other might be labeled rationalists. The strategies of the camps are conditioned by traditional notions of inside and outside. Debunkers consider themselves outsiders, beyond a deceptive show filled with tricky mirrors. Rationalists, by contrast, spend a great deal of time among mirrors, listening to explanations from the (...) overseers, attempting to absorb sideshow language, hoping to provide acceptable analytical accounts. If debunkers are intent on discovering generative and, presumably, hidden ideological inscriptions of a given discourse—its situation on what Amiri Baraka calls the “real side” of economic exchange and world exploitative power—rationalists are concerned to study discursive products, to decode or explain them according to forms and formulas that claim to avoid general views or judgments of ideology. Differentiating the camps also is what might be called a thermal gradient: the heat of the debunker’s passion is palpable. It is unnecessary to command him, in the manner of the invisible man’s tormentor, to “Get hot, boy! Get hot!” Rationalists, by contrast, do not radiate. They appear to have nothing personal at stake and remain coolly instructive and intelligently unflappable in their analyses.This tale of an Enlightenment legacy, as I have told it, contrasts a debunking body and rationalist soul. As I have suggested in my opening sentence, however, what is at issue is not so much two actual and substantially distinctive camps as two metonyms for dual approaches to a common subject—namely, notions of duality. My claim is that the Enlightenment reflexivity of academic discourse, devoted to, say, “the Other” and conceived in dualistic terms of self-and-other, expresses itself as an opposition. Thos whom I have called debunkers gladly accept the Other’s sovereignty as a bodily and aboriginal donnée; rationalists work to discover the dynamics of “othering” engaged in by a self-indulgent Western soul. The difficulty of producing usefully analytical or political results for either camp is occasioned by their joint situation within a post-Enlightenment field. Houston A. Baker, Jr. is the Albert M.

The personal, political, and aesthetic ideals that Irish modernists found embodied in the figure of Charles Stewart Parnell—independence, self-mastery, and a capacity for radical self-fashioning—have been well attested in Irish literary historiography. What has been less often noted is the centrality of sexual health to the conception, articulation, and emulation of those virtues, particularly when attempting to translate Parnell’s public persona to the stage. This essay addresses this lacuna by tracing how a medicalized and politicized conception of sex informed Irish (...) modernist efforts to dramatize the Parnell myth at the Abbey Theatre. It begins by establishing the hitherto underexamined ways in which the Parnell myth informed the infamously divisive sexual politics of J. M. Synge’s The Playboy of the Western World (1907), in which the fallen leader and his career provide a template for Christy Mahon and the virile autonomy he is held to embody. Building on this analysis, the essay proceeds to explore the ways in which Synge’s restaging of the Parnell myth, and the medicalized and politicized model of sex which underpinned it, informed Lady Augusta Gregory’s efforts to resuscitate (and sanitize) Parnell for Abbey audiences in 1911’s The Deliverer. Finally, through a close reading of Lennox Robinson’s largely overlooked 1918 play, The Lost Leader, the essay charts how the organicist and hereditarian model of sexual health upon which earlier iterations of the Parnell myth had rested began to give place to a more psychoanalytic model. It then identifies the implications of this shift for Robinson’s reading of Irish politics in the wake of the 1916 Easter Rising. In doing so, the essay highlights the ways in which sexual health emerged as an extra-moral normative framework in Irish political discourse, and it demonstrates how a Medical Humanities approach and a sensitivity to the social history of medicine in Ireland can enrich critical understandings of the Parnell myth and its modernist afterlives.

William Burnside was one of the three most important algebraists who were involved in the transformation of group theory from its nineteenth-century origins to a deeper twentieth-century subject. Building on work of earlier mathematicians, they were able to develop sophisticated tools for solving difficult problems. His works are of enormous historical importance; they remain also a source of inspiration and information. The works of his contemporaries, such as Klein, Frobenius, Schur, have been published as also have the works of (...) his immediate successors such as Phillip Hall. All of Burnside's papers are reproduced here, organized chronologically and with a detailed bibliography. Walter Feit has contributed a foreword, and a collection of introductory essays are included to provide a commentary on Burnside's work and set it in perspective along with a modern biography that draws on archive material. This is the first reference volume of Burnside's collected papers, enhanced by a series of critical essays on his work, and is important for group theorists and historians and philosophers of mathematics and fills the gap in this area of literature.

Using long-term anthropological observations at the Center for Biological and Environmental Nanotechnology in Houston, Texas, the article demonstrates in detail the creation of new objects, new venues and new modes of veridiction which have reoriented the disciplines of materials chemistry and nanotoxicology. Beginning with the confusion surrounding the meaning of ‘implications’ and ‘applications’ the article explores the creation of new venues (CBEN and its offshoot the International Council on Nanotechnology); it then demonstrates how the demands for a responsible, safe (...) or ethical science were translated into new research and experiment in and through these venues. Finally it shows how ‘safety by design’ emerged as a way to go beyond implications and applications, even as it introduced a whole new array of controversies concerning its viability, validity and legitimacy.

Abstract Medical futility is commonly understood as treatment that would not provide for any meaningful benefit for the patient. While the medical facts will help to determine what is medically appropriate, it is often difficult for patients, families, surrogate decision-makers and healthcare providers to navigate these difficult situations. Often communication breaks down between those involved or reaches an impasse. This paper presents a set of practical strategies for dealing with cases of perceived medical futility at a major cancer center. Content (...)

Houston, Texas, is a major U.S. city with, like many, a growing aging population. The purpose of this study and ultimate book chapter is to explore the views and perceptions of long-term care (LTC) residents, family members and health care providers. Individuals primarily in independent living and group residential settings were interviewed and studied. Questions emphasized the concepts of personal autonomy, dignity, quality and location of care and decision making. Although a small sample of participants were involved, consistency was (...) noted. Keeping the elderly in caring and loving home situations (theirs or family) was most preferred. Personal choice and independence were emphasized by residents, but family members needed to act as advocates. We also noted that the legal system emphasizes family control over individual decision making as competency declines with aging. Optimal personal decision making in the residents' best interest also became more difficult with loss of individual mental capacity. (shrink)

Locally-developed measures represent great tools for institutions to use in assessing student outcomes. Such measures can be easy to administer, can be cost-effective, and can provide meaningful data for improving student learning. However, many institutions struggle with questions surrounding the quality of their locally-developed assessments. Are their instruments reliable? Are their instruments valid? Can the data generated from these instruments be trusted to drive change and improvement? The good news for faculty, staff, and assessment professionals is that there are steps (...) they can take to address these concerns and help to ensure the validity and reliability of their processes. This article describes the development and testing of a novel research instrument of students’ attitudes and abilities relating to critical thinking, metacognition, and intellectual humility. Using a $1,000 assessment grant from Sam Houston State University (SHSU), Dr. Glenn Sanford and Dr. David Wright devised the early drafts of the instruments, collaborated with colleagues, and joined with Mr. Jeff Roberts, Director of Assessment at SHSU, to develop and to test this new instrument. What follows is a description of the development of the resulting research instrument, results from the factor analysis and reliability testing of that instrument, and an overview of how those results have been used to make further instrument improvements.

BackgroundAdverse Childhood Experiences have been associated with long-term physical and mental health conditions, toxic stress levels, developing unstable interpersonal relationships, and substance use disorders due to unresolved childhood adversities.AimsThis study assessed the perspectives of mental health providers regarding their adult patients’ coping with ACEs during COVID-19 in Houston, Texas. Specifically, we explored how individuals with ACEs are coping with the increased stresses of the pandemic, how MHPs may provide therapeutic support for individuals with ACEs during this pandemic, pandemic-related challenges (...) of accessing and utilizing mental health services for individuals with ACEs, and the awareness and treatment of ACEs among MHPs.MethodsTen in-depth semi-structured virtual interviews were conducted with licensed MHPs from November 2021 to April 2022 in Houston, Texas. Interviews were coded and analyzed for emerging themes through an inductive open coding approach to discover insights regarding coping with ACEs during COVID-19.ResultsFour key themes experienced by individuals with ACEs emerged from the MHP interviews: Maladaptive emotional dissonance and coping outlets during the pandemic, Difficulties with social connectedness and significance of social support, Heightened daily life stressors and coping with the ongoing disruption of the pandemic, and Changing interactions with the mental health system. Themes from this study highlighted that resilience, seeking treatment, and strong social support can help develop healthy coping strategies among individuals with ACEs.ConclusionThis study may help inform best clinical practices to develop interventions and policies regarding ACEs such as a resilience-promotion approach that targets all the socio-ecological levels. In addition, findings highlight the synergy of psychotherapeutic and pharmacological management via tele-health modalities, in helping individuals with ACEs continue receiving the care they deserve and need during a persistent pandemic and an uncertain future.

The distinction between concept and intuition is of the utmost importance for understanding Kant’s critical philosophy. For, as Kant himself claimed, all the distinctive claims of this philosophy rest on, and develop out of, a detailed account of the way all our cognition of things requires both intuitions and concepts.

In this essay, we examine the grounds, nature and content, status, acquisition and role, and justification of gratitude in Kant's ethical system, making use of student notes from Kant's lectures on ethics. We are especially interested in questions about the significance of gratitude in Kant's ethics. We examine Kant's claim that gratitude is a sacred duty, because it cannot be discharged, and explain how this claim is consistent with his insistence that “ought” implies “can.” We argue that for Kant a (...) proper understanding of self-esteem is importantly related to, if not necessary for, possession of the virtue of gratitude.

St. John of the Cross was aware of the fact that his mysticism resisted prosaic, discursive representation; however, most contemporary scholars have overlooked this radical component of his work. First, I trace the major philosophical influences on John’s work: Medieval Neoplatonism and Scholasticism. Second, by drawing on the Barthesian-Foucauldian concept of the author function, I demonstrate that the Mystical Doctor saw his poetry as free-standing, inexhaustible by even his own efforts to systematize key aspects of his poetry—an insurmountable task, which (...) he had to be compelled to compile and publish by the nuns he guided in spiritual direction.

Invitation to Peace Studies is the first textbook in the field to emphasize 21st-century research and controversies and to encourage the more frequent use of a gender perspective in analyzing peace, war, and violence. Recent empirical research forms the core of most chapters, but substantial attention is also given to faith-based ideas, movements, and peace pioneers. The book examines compelling contemporary topics like cyber warfare, drones, robots, digital activism, hactivism, the physiology of peace, rising rates of suicide, and peace through (...) health. It is also unique in its use of a single coherent perspective--that of a global peace network--to make sense of the historically unprecedented and interconnected web of diverse ideas, individuals, groups, organizations, and movements currently promoting peace across the world.

There are two prevailing interpretations of the status which Kant accorded his claims in the Critique of Pure Reason: 1) he is analyzing our concepts of cognition and experience; 2) he is making empirical claims about our cognitive faculties. I argue for a third alternative: on Kant's account, all cognition consists in a reflective consciousness of our cognitive faculties, and in critique we analyze the content of this consciousness. Since Strawson raises a famous charge of incoherence against such a position, (...) I begin by showing that this charge is misplaced. (shrink)

Thomas Reid is known as the founder of the common-sense school of philosophy, also known as the Scottish school. This group had considerable influence in Great Britain and in North America during the 19th century. Common sense is regarded as self-evident knowledge, the means by which we know the objects of the external world. These objects are known to us in their true sense and not as copies or ideas. This is the theory of natural realism and is the point (...) of difference with the theories of John Locke. In this collection of papers, many first delivered at a conference at the University of Glasgow held to celebrate the bicentenary of Reidâ??s death, the eminent contributors open a number and variety of doors into Reid and remind us that he remains a relevant force today.

It has been argued that infants possess a rich, sophisticated theory of mind that is only revealed with tasks based on spontaneous responses. A mature theory of mind implies the understanding that mental states are person-specific. Previous studies on infants’ understanding of motivational mental states such as goals and preferences have revealed that, by 9 months of age, infants do not generalize these motivational mental states across agents. However, it remains to be determined if infants also perceive epistemic states as (...) person-specific. Therefore, the goal of the present study was to use a switch agent paradigm with the classic false belief violation-of-expectation task. Results revealed that 16-month-old infants attributed true and false beliefs to a naïve agent—they did not perceive beliefs as person-specific. These findings indicate that infants’ understanding of beliefs is not as sophisticated as the rich mentalistic view suggests. (shrink)

What makes a subject''s motivationrational is its originating in her practicalreasoning. I explain the appeal of this thesisabout rational motivation, and explore itsrelation to recent discussions of internalismabout reasons for action. I do so in theservice of clarifying an important meta-ethicaldebate between Humean motivational skeptics andtheir Kantian opponents.

I arguethat properly adjudicating this debate requiresidentifying one (...) particular way in which thethesis about rational motivation has beendeveloped – namely, as a part of what I term``the traditional conception'''' of themotivational efficacy of practical reason.
