This article argues that at least very many judgments of homology rest on prior attributions of selected‐effect (SE) function, and that many of the “parts” of biological systems that are rightly classified as homologous are constituted by (are so classified in virtue of) their consequence etiologies. We claim that SE functions are often used in the prior identification of the parts deemed to be homologous and are often used to differentiate more restricted homologous kinds within less restricted ones. In doing (...) so, we discuss recent criticism of this view that has been offered (especially that offered by Paul Griffiths). *Received July 2007; revised November 2008. †To contact the authors, please write to: Department of Philosophy, 201 West Duke Building, Box 90743, Durham, NC 27708; e‐mail: [email protected] or [email protected].

Much previous study has been done on the degree spectra of prime models of a complete atomic decidable theory. Here we study the analogous questions for homogeneous models. We say a countable model A has a d-basis if the types realized in A are all computable and the Turing degree d can list $\Delta _{0}^{0}$ -indices for all types realized in A. We say A has a d-decidable copy if there exists a model B ≅ A such that the elementary (...) diagram of B is d-computable. Goncharov, Millar, and Peretyat'kin independently showed there exists a homogeneous A with a 0-basis but no decidable copy. We prove that any homogeneous A with a 0'-basis has a low decidable copy. This implies Csima's analogous result for prime models. In the case where all types of the theory T are computable and A is a homogeneous model with a 0-basis, we show A has copies decidable in every nonzero degree. A degree d is 0-homogeneous bounding if any automorphically nontrivial homogeneous A with a 0-basis has a d-decidable copy. We show that the nonlow₂ $\Delta _{2}^{0}$ degrees are 0-homogeneous bounding. (shrink)

Producing content-related gestures has been found to impact students’ learning, whether such gestures are spontaneously generated by the learner in the course of problem-solving, or participants are instructed to pose based on experimenter instructions during problem-solving and word learning. Few studies, however, have investigated the effect of (a) performing instructed gestures while learning concepts or (b) producing gestures without there being an implied connection between the gestures and the concepts being learned. The two studies reported here investigate the impact of (...) instructed hand movements on students’ subsequent understanding of a concept. Students were asked to watch an instructional video—focused on the concept of statistical model—three times. Two experimental groups were given a secondary task to perform while watching the video, which involved moving their hands to mimic the placement and orientation of red rectangular bars overlaid on the video. Students were told that the focus of the study was multitasking, and that the instructed hand movements were unrelated to the material being learned. In the content-match group the placement of the hands reinforced the concept being explained, and in the content-mismatch group it did not. A control group was not asked to perform a secondary task. In both studies, findings indicate that students in the content-match group performed better on the posttest, and showed less variation in performance, than did students in the content-mismatch group, with control students falling in between. Instructed hand movement—even when presented as an unrelated, secondary task—can affect students’ learning of a complex concept. (shrink)

This innovative critical study reinterprets Ludwig Wittgenstein's philosophy for the study of modernist and contemporary literature and brings Wittgenstein into literary conversations around problems of difficulty, ethical instruction, and the yearning for transformation. Central to Karen Zumhagen-Yekple͹'s book are her critical readings of key modernist texts by Franz Kafka, Virginia Woolf, and James Joyce. Throughout, Zumhagen-Yekplé brings to bear an interpretive framework that she derives from Wittgenstein's gnomic "Tractatus Logico-Philosophicus" (first published in English in 1922, the "annus mirabilis" of (...) modernism), which she treats not as a theory of logic or metaphysics but as a complex mock-theoretical puzzle. The book's final chapter turns to recent fiction by J. M. Coetzee, a living author conscious of his debts both to Wittgenstein and his modernist literary precursors. This book will interest students of literary modernism, Wittgenstein, and the interconnections between fiction and ordinary language philosophy. (shrink)

It is argued that it is not enough for feminist standpoint theory to argue that a feminine standpoint is better than a masculine one because of its genesis in female psycho-sexuality, it needs to show that its content is actually objectively more accurate. It then argues that historical feminists, such as Mary Wollstonecraft, have in fact tended to adopt a justice perspective, grounded in reason, which is objectively of greater value than that developed by many male authors, because these historical (...) writers have failed to think that justice is incompatible with feeling and emotion and have attempted to combine the importance of sympathy, empathy, and feeling with the need for equality, liberty, and fairness.

Background Moral distress is reported to be a critical force contributing to intensifying rates of anxiety, depression and burnout experienced by healthcare workers. In this paper, we examine the moral dilemmas and ensuing distress personally and collectively experienced by healthcare workers while caring for patients during the pandemic. Methods Data are drawn from free-text responses from a cross-sectional national online survey of Australian healthcare workers about the patient care challenges they faced. Results Three themes were derived from qualitative content analysis (...) that illuminated the ways in which moral dilemmas and distress were relationally experienced by healthcare workers: (1) the moral ambiguity of how to care well for patients amid a rapidly changing work environment; (2) the distress of witnessing suffering shared _between_ healthcare workers and patients; and (3) the distress of performing new forms of invisible work in the absence of institutional recognition. These findings reveal that moral distress was a strongly shared experience. Conclusions Findings advance understandings of moral distress as a relational experience, collectively felt, constituted, and experienced by healthcare workers. Considering how to harness collective solidarity in effectively responding to moral distress experienced across the frontline healthcare workforce is critical. (shrink)

An array of pressing but conceptually perplexing questions in ethics---questions concerning group rights, collective responsibility, and the ethics of nationalism---would seem to require for their resolution answers to the no less perplexing questions of what social groups are and what membership in them amounts to. In this dissertation, I offer an analysis of the concept of what I call an 'ethnic identity group' and argue that questions about ethics and ethnicity or nationality are best understood as questions about such groups (...) and their agency. The main argument for the analysis involves showing its usefulness for understanding how group membership might be involved in personal moral identity and individual agency. ;The analysis I offer makes use of Max Weber's idea that the concept of a social group is analyzable in terms of the possibility that certain kinds of social action will be performed. A Weberian analysis of a kind of social group involves a characterization of the types of social action that are possible in relation to groups of that kind. After responding to Margaret Gilbert's arguments against Weberian analyses of social groups and related phenomena, I suggest that one central social concept is that of a group defined in terms of the availability for group members of standing in a particular relation to an idea of the group, where that idea is, more specifically, an idea of a collective agent. This is the concept of an identity group. What distinguishes members of an identity group from nonmembers is the availability for the former of standing to the group in a relation I call 'moral alignment'. Roughly, an individual aligns herself with a group to the extent that she sees the group's agency as an extension of her own. This concept of moral alignment is a development of Aristotle's view that through shared deliberation and action, friends in a perfect friendship become "other selves" for each other. A group member is socially placed so as to have access to the idea that other members may act for her and she for them. If she aligns herself with the group, the group becomes another self for her, and she may act as a member of the group. An ethnic identity group is a collection of individuals, each of whom may align himself with an idea of the group---where that idea is an idea of a particular collective agent, whose collectivity rests on the shared ancestry of the collected individuals---and each of whom may, therefore, act and respond emotionally as a member of the group.

Within the realm of nano-, bio-, info- and cogno- (or NBIC) technosciences, the ‘power to change the world’ is often invoked. One could dismiss such formulations as ‘purely rhetorical’, interpret them as rhetorical and self-fulfilling or view them as an adequate depiction of one of the fundamental characteristics of technoscience. In the latter case, a very specific nexus between science and technology, or, the epistemic and the constructionist realm is envisioned. The following paper focuses on this nexus drawing on theoretical (...) conceptions as well as empirical material. It presents an overview of different technoscientific ways to ‘change the world’—via contemplation and representation, intervention and control, engineering, construction and creation. It further argues that the hybrid character of technoscience makes it difficult (if not impossible) to separate knowledge production from real world interventions and challenges current science and technology policy approaches in fundamental ways.

ObjectivesThis pilot study sought to develop and evaluate a novel online group-based intervention to help breast cancer survivors make healthy lifestyle changes intended to yield not only beneficial physical outcomes but also greater behavioral, and psychosocial well-being.MethodsAn exploratory single-arm, mixed-method triangulation design was employed to evaluate the feasibility and preliminary effectiveness of the HLM-ABC intervention for overweight BCSs. Fourteen women participated in the 10-week intervention and completed quantitative measures of the above-mentioned outcomes at baseline, post-treatment, 6-month, and 12-month follow-up time (...) points. Qualitative data were obtained post-treatment via semi-structured interviews and a treatment satisfaction questionnaire.ResultsParticipants lost an average of 2.83% of their baseline weight by 1-year follow-up, equal to a small effect size. Despite achieving only modest weight loss, participants achieved meaningful gains in the form of increased physical activity, discovery of gratifying movement, more intuitive eating habits, greater bodily and emotional awareness, and positive shifts in beliefs about being able to make healthy choices regarding food and physical activity. Furthermore, they demonstrated a slight improvement in body image and described feeling more self-compassionate, empowered, and acknowledging of variables beyond control that can present barriers to change.ConclusionAfter completing a 10-week online program, participants achieved meaningful and lasting changes on a number of healthful indicators, even when this did not correspond with a significant reduction in weight. Findings highlight the complex, multifaceted nature of “health” and lend support for promotion of healthier lifestyle following cancer treatment that encompasses not only physical weight, but also behavior, psychosocial well-being, and circumstances such as life-preserving hormonal treatments.

Over several years, genetic studies in the model system, Drosophila melanogastor, have uncovered genes that when mutated, lead to a block in myoblast fusion. Analyses of these gene products have suggested that Arp2/3‐mediated regulation of the actin cytoskeleton is crucial to myoblast fusion in the fly. Recent advances in imaging in Drosophila embryos, both in fixed and live preparations, have led to a new appreciation of both the three‐dimensional organization of the somatic mesoderm and the cell biology underlying myoblast fusion.

In the last five years there have been a number of results about the computable content of the prime, saturated, or homogeneous models of a complete decidable theory T in the spirit of Vaught's "Denumerable models of complete theories" combined with computability methods for degrees d ≤ 0′. First we recast older results by Goncharov, Peretyat'kin, and Millar in a more modern framework which we then apply. Then we survey recent results by Lange, "The degree spectra of homogeneous models," which (...) generalize the older results and which include positive results on when a certain homogeneous model of T has an isomorphic copy of a given Turing degree. We then survey Lange's "A characterization of the 0-basis homogeneous bounding degrees" for negative results about when does not have such copies, generalizing negative results by Goncharov, Peretyat'kin, and Millar. Finally, we explain recent results by Csima, Harizanov, Hirschfeldt, and Soare, "Bounding homogeneous models," about degrees d that are homogeneous bounding and explain their relation to the PA degrees.

GILLETT K. Nursing Inquiry 2012; 19: 297–307 A critical discourse analysis of British national newspaper representations of the academic level of nurse education: too clever for our own good?This critical discourse analysis examines articles about the academic level of nurse education that appeared in British national newspapers between 1999 and 2009. British newspaper journalists regularly attribute problems with recruitment into nursing and nursing care to the increasing academic nature of nurse education. It is impossible to separate discourse about nurse education (...) from the wider nursing discourse. Many journalists laud a traditional and stereotypical construct of nurse identity and suggest that increasing nurse education produces nurses who are ‘too clever to care’. This article argues that whilst nurses lack a voice in the National press, they have little input into the construction of newspaper discourse about nurse education and subsequently, limited influence on resulting public opinion, government policy and the morale of nurses.

-/- CONCLUSION “The experience in California is clear. Affirmative action has helped to dismantle barriers such as "old boys' networks" that have excluded not only women and individuals of racial or ethnic minorities, but also white American men who did not belong to networks of privilege. Affirmative action has also worked to ensure that our schools, workplaces, and other social institutions fully use our diverse talents, thereby helping our government and social institutions to better serve their communities. -/- In short, (...) affirmative action has helped to bring out the best in us as a society. It challenges us to have the courage of our convictions that: (1) we do want a truly equal opportunity society; and (2) we believe that all Americans, including women and minorities, are competent individuals who have talents to contribute. Passing the CCRI would completely eliminate affirmative action, and thus have the same effect as "throwing the baby out with the bathwater." The "baby" —active and affirmative commitment to equal opportunity— is barely out of its infancy. We must not now abandon our commitment, just when we have taken our first steps towards creating a truly equal opportunity society.” -/- (This essay was written against the backdrop of legislative efforts in the mid 1990s, to overturn “affirmative action” policies at educational institutions, which had given more equal access to higher education for students from previously under-represented communities, particularly white women but also racialized communities. By mischaracterizing affirmative action programs as “gender or racial preferences”, opponents were able to pass the 1996 ballot measure, Proposition 209, the so-called “California Civil Rights Initiative” (CCRI). The ban on “preferences” gained the support of 54.6% of all California voters, including 58% of white women and 66% of white men voters. Use of language was key, as a slight majority of Americans approved of some affirmative actions but opposed racial preferences. The CCRI has had a huge toll on Latino and African American enrollment at UC Berkeley and UCLA, which has never recovered. State contracts for firms owned by women and minorities also dropped sharply. Similar initiatives failed in some states but succeeded elsewhere. See online Encyclopedia). (shrink)

Current brain research gives us the knowledge we need to create an Integral Society in every public school in America, pre-K through 12th and college level as well. The needed instructional strategies and curriculum development practices have been clearly described (Kovalik and Olsen, 2004) and are well within the grasp of current teachers. What is missing is the political will to implement what we know.

This paper considers the relationship between scientific rationality and emotional value in determining ideas about canine biology in North America. While science has been assumed to be objective, unassailable and devoid of value judgments, esoteric theories concerning wild predators have changed radically over time. Biologists acted as important agents in the campaign to eradicate Canis lupus from the USA during the late 1800s and early 1900s. From the 1920s onwards, scientists promulgated ecological ideas in order to redeem native carnivores. This (...) paper suggests that, in extermination and rehabilitation phases, biologists formed their opinions of resident lupines using scientific dogma and moral precepts. By delineating the process of wolf rehabilitation in the USA, this paper situates science as a shifting body of knowledge, a way of comprehending the environment that cannot be viewed apart from cultural conceptions of biology, ethics and aesthetics.

The risk of tort liability for health maintenance organizations and other managed care plans has dramatically increased in recent years. This is due in part to the growing percentage of health care rendered through managed care plans. The cost-containment mechanisms commonly used by managed care plans, such as limiting access to services and/or choice of providers, creates a climate ripe for disputes that may end up in court. As dissatisfied patients and providers seek recourse in the courts, tort doctrines are (...) extended and new legal theories emerge as needed. For example, the concepts of direct and vicarious tort liability developed in the hospital context have been extended by courts to encompass HMOs. vicarious liability claims, based on ostensible agency or respondeat superior doctrines, have been brought against HMOs and managed care plans for negligent treatment by physicians selected to provide care to members.

Hundreds of cottages and cabins, mansions and houses line the shores of Lake Minnetonka, one of Minnesota's most beautiful lakes and site of some of the state's most coveted properties. Legendary Homes of Lake Minnetonka invites readers into thirty of these dwellings - built by families like the Washburns, the Pillsburys, and the Daytons. Evocative words and stunning color photographs guide readers through these beautifully designed and furnished homes. Portrayed in elegant detail are interiors of renovated Victorian cottages and rustic (...) cabins, as well as those of houses designed by modernist masters like William Lescaze and Philip Johnson. Photographer Karen Melvin takes viewers through the front door, showing living rooms furnished with Mies van der Rohe couches and Frank Lloyd Wright chairs and walls adorned with works by Robert Motherwell and Damien Hirst. Author Bette Jones Hammel relates the homes' histories of ownership and details the many renovations they have seen over time, renovations that have attempted to retain the homes' character and extend their lifespan. For the best views of the exteriors of these homes, you would need a boat. To see the interiors, you would need an invitation. Hammel and Melvin have chosen the most interesting houses - both architecturally and historically - and painstakingly scouted out the best vantage points, both inside and out, to provide a personal tour of these spectacular homes.

Alterations to cognitive function are often reported with depression and anxiety symptoms, yet few studies have examined the same associations with mental well-being. This study examined the association between mental well-being, depression and anxiety symptoms and cognitive function in 1502 healthy adult monozygotic and dizygotic twins, and the shared/unique contribution of genetic and environmental variance. Using linear mixed models, mental well-being was positively associated with sustained attention, inhibition, cognitive flexibility, motor coordination and working memory, whereas depression and anxiety symptoms were (...) associated with poorer sustained attention, inhibition, cognitive flexibility and executive function. Bivariate twin modelling showed well-being shared a small environmental correlation with motor coordination and a small genetic correlation with working memory. Trivariate twin modelling showed well-being shared a small genetic correlation with inhibition, whereas depression and anxiety symptoms shared a small environmental correlation with inhibition. The remaining variance was mostly driven by unique G and/or E variance. Overall, well-being and depression and anxiety symptoms show both independent and shared relationships with cognitive functions but this is largely attributable to unique G or E variance and small shared G/E variance between pairs of variables.

We defend the claim that there can be testimonial transfer of reasons against Steinig’s recent objections. In addition, we argue that the literature on testimony about moral reasons misunderstands what is at stake in the possibility of second-hand orientation towards moral reasons. A moral community faces two different but related tasks: one theoretical (working out what things are of genuine value and how to rank goods and ends) and one practical (engaging in joint action and social coordination). In between, simultaneously (...) theoretical and practical, lies the activity of co-deliberation. Virtuous participation in co-deliberation can require limited moral deference. Refusal to recognize this, combined with excess self-trust, can derail co-deliberation. (shrink)

Modern feminism has been preoccupied with difference. An early and continuing struggle has been to acknowledge differences between men and women without having those differences used against women. That struggle has been extended to recognizing differences among women. By the end of the 1980s, women were calling for a in which Although cautioning words were raised by some, feminists in general moved to trying not only to recognize but to celebrate difference.
