Let X be a set, and let $\hat{X} = \bigcup^\infty_{n = 0} X_n$ be the superstructure of X, where X 0 = X and X n + 1 = X n ∪ P(X n ) (P(X) is the power set of X) for n ∈ ω. The set X is called a flat set if and only if $X \neq \varnothing.\varnothing \not\in X.x \cap \hat X = \varnothing$ for each x ∈ X, and $x \cap \hat{y} = \varnothing$ for x.y (...) ∈ X such that x ≠ y, where $\hat{y} = \bigcup^\infty_{n = 0} y_n$ is the superstructure of y. In this article, it is shown that there exists a bijection of any nonempty set onto a flat set. Also, if W̃ is an ultrapower of X̂ (generated by any infinite set I and any nonprincipal ultrafilter on I), it is shown that W̃ is a nonstandard model of X: i.e., the Transfer Principle holds for X̂ and W̃, if X is a flat set. Indeed, it is obvious that W̃ is not a nonstandard model of X when X is an infinite ordinal number. The construction of flat sets only requires the ZF axioms of set theory. Therefore, the assumption that X is a set of individuals (i.e., $x \neq \varnothing$ and a ∈ x does not hold for x ∈ X and for any element a) is not needed for W̃ to be a nonstandard model of X.

I refer to Charles Dorn's (...) Mind in Art, my book Art and Cognition, and Elliot Eisner's The Arts and the Creation of Mind, with the publication of the latter providing the occasion for this article.1 Each of these texts makes its case for the arts in education on somewhat similar grounds. All three share the view that the creation and understanding of works of art, though endowed with feeling and emotion, are nevertheless cognitive endeavors. But why have so many books appeared on the topic of cognition at this time? To answer this question it becomes necessary to describe the changes in our understanding of cognition and the problems these have created for the arts in education.Once cognition was the term used to designate propositional thinking with verbal and numerical symbols, whereas the current sense of the term embraces all forms of thought including mental images obtained through perception. In short it includes all forms of sentience by which the human organism comes to know itself and its environment. This change was to have a major impact upon curriculum reform initiatives in all studies but it was to have a revolutionary impact upon education in the arts for reasons explained later in this essay. However, an adequate story of cognition in the arts cannot be told without a discussion of Eisner's contributions to this discourse. The Waning of Behaviorism For the first half of the twentieth century the psychology that dominated educational practice was behaviorism. Its proponents included psychologists like Edward L. Thorndike, James B. Watson, and B.F. Skinner.2 Each strove to create a science of psychology that would match the rigor of physics or chemistry, where causes in relation to effects would be carefully observed and measured, making the explanation, prediction, and control of phenomena possible, especially those behaviors that fall under the control of the classroom teacher. The formation of connections called stimulus-response (S-R) bonds had become the molar unit to explain learning, much [End Page 71] like the way that differences in the structure of the atom was used to explain the behavior of the chemical elements of the Periodic Table. This bond between environmental stimuli and the organism's response was seen as the elementary unit of behavior while the IQ had become its measure. Invisible notions like mind and imagination were banished to metaphysical philosophy, outside the legitimate bounds of science.Though behaviorists never denied the existence of higher order thinking that is, abstract, sense-free thinking as found in pure mathematics, they were unable to explain how these human capacities emerge through the accumulation of such rudimentary stimulus-response events. Nevertheless, they recognized that humans do have a capacity for thinking that relies heavily upon symbols like words, numbers and the like. Moreover, certain subjects that require reason and logic, like math and theoretical physics, would be inconceivable without such symbols and the rules by which these are manipulated. By contrast it was assumed that the arts, which relied on sensory images, either did not employ this type of propositional thought, or did so to a far lesser degree. Thus the arts could be dispatched to the noncognitive or affective domains with little or no reduction in the learner's cognitive capacities. Indeed, these noncognitive realms, which gave play to feelings and emotions, were often seen as inimical to the acquisition of rational powers of thought. Intellectual power as it was then understood, required that feelings and emotions be brought under the control of reason.As long as behaviorism served as the dominant paradigm, the school curriculum could be divided into two or three broad divisions...

Although virtually all comparative research about risk perception focuses on which hazards are of concern to people in different culture groups, much can be gained by focusing on predictors of levels of risk perception in various countries and places. In this case, we examine standard and novel predictors of risk perception in seven sites among communities affected by a flood in Mexico (one site) and volcanic eruptions in Mexico (one site) and Ecuador (five sites). We conducted more than 450 interviews (...) with questions about how people feel at the time (after the disaster) regarding what happened in the past, their current concerns, and their expectations for the future. We explore how aspects of the context in which people live have an effect on how strongly people perceive natural hazards in relationship with demographic, well-being, and social network factors. Generally, our research indicates that levels of risk perception for past, present, and future aspects of a specific hazard are similar across these two countries and seven sites. However, these contexts produced different predictors of risk perception—in other words, there was little overlap between sites in the variables that predicted the past, present, or future aspects of risk perception in each site. Generally, current stress was related to perception of past danger of an event in the Mexican sites, but not in Ecuador; network variables were mainly important for perception of past danger (rather than future or present danger), although specific network correlates varied from site to site across the countries.

Arthur Danto is the Johnsonian Professor Emeritus of Philosophy at Columbia University and the most influential philosopher of art in the last half century. As an art critic for The Nation for 25 years and frequent contributor to other widely read outlets such as the New York Review of Books, Danto also has become one of the most respected public intellectuals of his generation. He is the author of some two dozen important books, along with hundreds of articles and (...) reviews which have been the center of both controversy and discussion. In this volume Danto offers his intellectual autobiography and responds to essays by 27 of the keenest critics of his thought from the worlds of philosophy and the arts. The book includes 16 pages of color art reproductions. Danto is the author dozens of books on art, philosophy, the philosophy of art, and art criticism. He is a rare philosopher who is also a public intellectual. (shrink)

This essay argues that the affective component inherent in the enthymeme is the essence of aristotle's concept of the enthymeme as practical reasoning. 'affective component' refers to emotions and feelings. The three proofs of the thesis are the etymology of 'enthymeme', Aristotle's works on human action and practical wisdom, And aristotle's rhetoric. These sources show the inherent relation between enthymemes and phronesis, Or practical reasoning, Not nous, Or abstract intellect.

The aim of the My Character project was to develop a better understanding of how interventions designed to develop character might enhance moral formation and futuremindedness in young people. Futuremindedness can be defined as an individual’s capacity to set goals and make plans to achieve them. Establishing goals requires considerable moral reflection, and the achievement of worthwhile aims requires character traits such as courage and the capacity to delay gratification. The research team developed two new educational interventions – a website (...) and a hard-copy journal – with the specific aim of developing future-mindedness. After development, the website and journal were piloted over a one-year period by over 1,000 11–14 year olds in six schools across England. Various research methods, including group interviews and case studies, were implemented to assess impact. In addition, a pilot RCT was conducted to assess the feasibility of using experimental methods to measure character. The main findings from the research are that: - Students benefit from opportunities in school to think about future-mindedness; this can be successfully taught through character education. - Harnessing new technology, such as the Internet, offers exciting opportunities for character education. - It is beneficial to investigate the impact of new character education resources in order to bring greater clarity about ‘what works’. The most useful approach is a mixed methods one that allows for triangulation of evidence. - It is possible to run RCTs and other experimental research in schools to assess developmental projects of this kind, but applying the method in schools and creating suitable outcome measures present challenges for researchers. - A positive indicator of the success is that five out of the six pilot schools have embedded My Character into their curriculum. In addition, many new schools, both in Britain and internationally, have started to use the website and / or journal. This report describes the research, analyses the impact of My Character and concludes with recommendations for policy makers, practitioners and researchers embarking on similar projects. These recommendations include: i) advocating that schools create space in the curriculum to teach future-mindedness through character education; ii) enhancing traditional character education teaching methods with opportunities brought by Internet technologies; iii) evaluating character education interventions using triangulated evidence drawn from a mixture of research methods.

Trisomy 13 and 18 are rare chromosomal abnormalities associated with high morbidity and mortality. Improved survival rates and increased prevalence of aggressive medical intervention have resulted in families and physicians holding different perspectives regarding the appropriate management of children with T 13/18. Families were invited for open-ended interviews regarding their experiences with the medical care of a child with T 13/18 over the past 5 years. Seven of 33 invited families were surveyed; those who had spent more than 40 days (...) in the hospital were most likely to accept the invitation. Grounded theory technique was used to analyze the interviews. This method elicited four key themes regarding family perspectives on children with T 13/18: they are unique and significant, they transform the lives of others, their families can feel overwhelmed and powerless in the medical setting, their families are motivated to “carry the torch” and tell their story. Families also emphasized ways in which Internet support groups can provide both positive and negative perspectives. The ensuing discussion explores the difficulties of parents and physicians in forecasting the impact that T 13/18 will have on families and emphasizes a narrative approach to elicit a map of the things that matter to them. The paper concludes that while over-reliance on dire prognostic data can alienate families, examining the voice, character and plot of patient stories can be a powerful way for physicians to foster shared decision-making with families.

There is widespread agreement among large segments of western society that we are living in a period of hard times. At first glance such a belief might seem exceedingly odd. After all, persons in western society find themselves living in a time of unprecedented material abundance. Hunger and disease, evils all too familiar to the members of earlier generations, although far from eradicated from modern life, are plainly on the wane. Persons alive today can look forward to healthier, longer, and (...) more comfortable lives than those of their grand parents. Nevertheless, the feeling that life today is especially difficult is rampant in government, in the media, in popular books, and in academic circles. Western society is perceived in many quarters as wracked by crises of all sorts-of faith, of power, of authority, of social turmoil, of declining quality in workmanship and products, and of a general intellectual malaise afflicting both those on the Left and the Right. A tone of crisis permeates the language of public life. Editorials in major newspapers are full of dire warnings about the dangers of unbridled egoism, avarice and greed, and the risks and horrors of pollution, overpopulation, the arms race, crime, and indulgent lifestyles.

There is a growing consensus in Britain on the importance of character, and on the belief that the virtues that contribute to good character are part of the solution to many of the challenges facing modern society. Parents, teachers and schools understand the need to teach basic moral virtues to pupils, such as honesty, self-control, fairness, and respect, while fostering behaviour associated with such virtues today. However, until recently, the materials required to help deliver this ambition have been missing in (...) Britain. The Knightly Virtues Programme, devised by the Jubilee Centre for Character and Virtues, aims to help solve this challenge. The programme, designed for 9 to 11 year olds, draws on selected classic stories to help teach moral character in schools. This approach has proved to be popular with children and teachers, with more than 5,000 pupils from one hundred schools having participated in the programme so far. Fifty-five of these schools and 3,272 pupils were directly involved in different stages of the research. Based at the University of Birmingham, the Jubilee Centre houses leading academics dedicated to researching the various ways in which good character, which underpins the building blocks of society, can be developed. Recent research from the Centre has shown that the qualities that make up character can be learnt and taught, and suggests that we need a new emphasis on their importance in schools and in professional education. This report from the Centre into the use of classic literature within schools sets out the ways in which the Knightly Virtues Programme is able to develop the virtue literacy of school pupils, and the extent to which an understanding and awareness of good moral character can make positive changes to behaviour. The impact of the programme has been tested using several rigorous research methods, detailed in this report alongside their findings, which provide substantial empirical evidence for the effectiveness of using stories to develop virtue literacy.

Physicians generally recommend that patients resuscitated with naloxone after opioid overdose stay in the emergency department for a period of observation in order to prevent harm from delayed sequelae of opioid toxicity. Patients frequently refuse this period of observation despiteenefit to risk. Healthcare providers are thus confronted with the challenge of how best to protect the patient’s interests while also respecting autonomy, including assessing whether the patient is making an autonomous choice to refuse care. Previous studies have shown that physicians (...) have widely divergent approaches to navigating these conflicts. This paper reviews what is known about the effects of opioid use disorder on decision-making, and argues that some subset of these refusals are non-autonomous choices, even when patients appear to have decision making capacity. This conclusion has several implications for how physicians assess and respond to patients refusing medical recommendations after naloxone resuscitation. (shrink)

Adaptive immunity provides the unique ability to respond to a nearly infinite range of antigenic determinants. Given the inherent plasticity of the adaptive immune system, a series of tolerance mechanisms exist to reduce reactivity toward self. While this reduces the probability of autoimmunity, it also creates an important gap in adaptive immunity: the ability to recognize microbes that look like self. As a variety of microbes decorate themselves in self‐like carbohydrate antigens and tolerance reduces the ability of adaptive immunity to (...) react with self‐like structures, protection against molecular mimicry likely resides within the innate arm of immunity. In this review, we will explore the potential consequences of microbial molecular mimicry, including factors within innate immunity that appear to specifically target microbes expressing self‐like antigens, and therefore provide protection against molecular mimicry.

One of the most fundamental features of the body plan of arthropods is its segmental design. There is considerable variation in segment number among arthropod groups (about 20‐fold); yet, paradoxically, the vast majority of arthropod species have a fixed number of segments, thus providing no variation in this character for natural selection to act upon. However, the 1000‐species‐strong centipede order Geophilomorpha provides an exception to the general rule of intraspecific invariance in segment number. Members of this group, and especially our (...) favourite animal Strigamia maritima, may thus help us to understand the evolution of segment number in arthropods. Evolution must act by modifying the formation of segments during embryogenesis. So, how this developmental process operates, in a variable‐segment‐number species, is of considerable interest. Strigamia maritima turns out to be a tractable system both at the ecological level of investigating differences in mean segment number between populations and at the molecular level of studying the expression patterns of developmental genes. Here we report the current state of play in our work on this fascinating animal, including our recent finding of a double‐segment periodicity in the expression of two Strigamia segmentation genes, and its possible implications for our understanding of arthropod segmentation mechanisms in general.

Clinical bioethics is big business. There are now hundreds of people who bioethics in community and university hospitals, nursing homes, rehabilitation and home care settings, and some who play the role of clinical ethics consultant to transplant teams, managed care companies, and genetic testing firms. Still, there is as much speculation about what clinically active bioethicists actually do as there was ten years ago. Various commentators have pondered the need for training standards, credentials, exams, and malpractice insurance for ethicists engaged (...) in clinical consultation. Much of the discussion seems to accept an implicit presumption that all clinical ethics consultation practices look pretty much alike. But is this accurate? What do clinical ethicists do, how and where do they do it, and what kind of clinical ethics is useful in the hospital and in other settings? (shrink)

A tension has been identified between the acquisition and participation metaphors for learning, and it is generally agreed that this tension has still not been adequately resolved. In this paper, we offer an alternative to the acquisition and participation metaphors for learning: the metaphor of mastering. Our claim is that the mastering metaphor, as grounded in inferentialism, allows one to treat both the acquisition and participation dimensions of learning as complementary and mutually constitutive. Inferentialism is a semantic theory which explains (...) concept formation in terms of the inferences individuals make in the context of an intersubjective practice of acknowledging, attributing, and challenging one another's commitments. We first introduce the key concepts of inferentialism and consider the perspective on learning that inferentialism inspires. Then, we condense the lessons of the inferentialist concepts into a single mastering metaphor for learning and argue that learning consists in the process by which learners come to master concepts and practices. We conclude by discussing how the mastering metaphor could be put to work in a theoretical reconciliation of the cognitive and sociocultural dimensions of learning. (shrink)

Cognitive control of physical activity and sedentary behavior is receiving increased attention in the neuroscientific and behavioral medicine literature as a means of better understanding and improving the self-regulation of physical activity. Enhancing individuals’ cognitive control capacities may provide a resilient means to increase physical activity and reduce sedentary behavior. First, this paper reviews emerging evidence of the antecedence of cognitive control abilities in successful self-regulation of physical activity, and in precipitating self-regulation failure that predisposes to sedentary behavior. We then (...) highlight the brain networks that may underpin the cognitive control and self-regulation of physical activity, including the default mode network, prefrontal cortical networks and brain regions and pathways associated with reward. We then discuss research on cognitive training interventions that document improved cognitive control and that suggest promise of influencing physical activity regulation. Key cognitive training components likely to be the most effective at improving self-regulation are also highlighted. The review concludes with suggestions for future research. (shrink)
