During the pandemic lockdown period, residents had to stay at home and increased stress and other mental health problems have been associated with the lockdown period. Since most public parks were closed, community parks within gated residential areas became the most important green space in Chinese cities, and the use of such space might help to reduce the residents’ stress levels. This study aimed to investigate to what extent urban residents in China used community parks, engaged in outdoor activity during (...) the lockdown period and if the use of such spaces helped to reduce their stress levels. An online questionnaire survey was carried out from 23 March to 23 April 2020. Ordinary Least Squares regression was used to analyse the association between community park use, outdoor activity, willingness to engage in outdoor activity, and stress level. All results have been further analysed by two-sampled t-test to explore the difference between young and old age groups. We found that the overall self-reported stress level of the respondents was relatively moderate during the lockdown period. Respondents had generally reduced their use of community parks and engagement in outdoor activity. There was no significant association between stress level and the use of community parks or the engagement in outdoor activities. However, we found that older people showed much lower stress levels, used community parks more frequently, and engaged in more outdoor activities than younger adults. The findings suggest that outdoor activities and spatial characteristics in urban China differ from Western studies and advance the need to integrate the stress management role of community parks with urban green space policy to optimise the use of community parks blended in with everyday life, particularly during the lockdown period.

The imbalance between supply of organs for transplantation and demand for them is widening. Although the current international drive to re-establish procurement via non-heart beating organ donation/donor is founded therefore on necessity, the process may constitute a desirable outcome for patient and family when progression to brain stem death does not occur and conventional organ retrieval from the beating heart donor is thereby prevented. The literature accounts of this practice, however, raise concerns that risk jeopardising professional and public confidence in (...) the broader transplant programme. This article focuses on these clinical, ethical, and legal issues in the context of other approaches aimed at increasing donor numbers. The feasibility of introducing such an initiative will hinge on the ability to reassure patients, families, attendant staff, professional bodies, the wider public, law enforcement agencies, and the media that practitioners are working within explicit guidelines which are both ethically and legally defensible.

Legislation that authorises controversial organ procurement strategies but ignores respect for autonomy is flawed in principle and predictably unworkable in practiceThe UK Human Tissue Act 2004,1 designed to regulate all activity involving human tissue, organs, or bodies, was introduced in the House of Commons in December 2003, received Royal Assent on 15 November 2004,2 and has been partially implemented by Commencement Orders from April 2005. The new act, which repeals and replaces the Human Tissue Act 1961, the Anatomy Act 1984, (...) and the Human Organ Transplants Act 1989, has its origins in events of serious public concern, namely the retained organs scandals at Bristol Royal Infirmary3 and the Royal Liverpool Childrens’ Hospital.4 The act is correspondingly dominated by regulation of postmortem examinations and retention of human tissue, with consistent emphasis on the need for fully informed consent. Compliance with these requirements is now mandatory with the threat of up to three years’ imprisonment and/or fines for any deviation.The impact of the original proposals within the bill on research and the clinical practice of pathology have been carefully considered and documented,5 with subsequent amendments to ameliorate professional concerns.6 The act, however, also carries significant implications for medical practice in areas where donor recruitment for transplantation can take place, and representations on these aspects during readings of the bill7 have produced neither clarification, justification, nor amendment within the final legislation.Section 43 will make it lawful for hospital authorities “to take steps for the purpose of preserving the part for use for transplantation and to retain the body for that purpose”. The original explanatory notes for the bill8 while it proceeded through parliament implied that such action, prior to consent to transplantation being sought, was then lawful, clause 44 as section 43 ….

Developments in neuroscience have raised the possibility that pharmaceuticals may be used to enhance memory, mood, and attention in people who do not have an illness or disorder, a practice known as “cognitive enhancement.” We describe historical experiences with two medicinal drugs for which similar enhancement claims were made, cocaine in the late 19th and early 20th centuries, and amphetamines in the mid 20th century. These drugs were initially introduced as medicinal agents in Europe and North America before becoming more (...) widely used for a variety of purposes, including what would nowadays be considered cognitive enhancement. Their trajectory of use conformed to the typical use cycle of psychotropic drugs. There was an initial steep rise in prescribing for medical use, followed by expanded nonmedical use that was fueled by enthusiasm for the drugs’ effects. As the number of regular users increased, problems related to use (such as addiction) became apparent, societal concern increased, and laws were passed banning nonmedical use and eventually, medical use. This historical experience draws attention to the adverse side effects of enhancement use that only become apparent with regular, wide-scale use of a drug. We highlight the similarities between the enthusiasms for cocaine and amphetamines and the current enthusiasms for using prescription stimulants for cognitive enhancement. We argue bioethicists should not encourage the cognitive enhancement use of drugs such as methylphenidate in the absence of evidence on the efficacy and safety of their use for cognitive enhancement purposes.

Let V be the cumulative set theoretic hierarchy, generated from the empty set by taking powers at successor stages and unions at limit stages and, following [2], let the primitive language of set theory be the first order language which contains binary symbols for equality and membership only. Despite the existence of ∀∀-formulae in the primitive language, with two free variables, which are satisfiable in V but not by finite sets ([5]), and therefore of ƎƎ∀∀ sentences of the same language, (...) which are undecidable in ZFC without the Axiom of Infinity, truth in V for Ǝ*∀∀-sentences of the primitive language, is decidable ([1]). Completeness of ZF with respect to such sentences follows. (shrink)

Over the past several decades, medical ethics has gained a solid foothold in medical education and is now a required course in most medical schools. Although the field of medical ethics is by nature eclectic, moral philosophy has played a dominant role in defining both the content of what is taught and the methodology for reasoning about ethical dilemmas. Most educators largely rely on the case‐based method for teaching ethics, grounding the ethical reasoning in an amalgam of theories drawn from (...) moral philosophy, including consequentialism, deontology, and principlism.In this article we hope to make a case for augmenting the focus of education in medical ethics. We propose complementing the traditional approach to medical ethics with a more embedded approach, one that has been described by others as “microethics,” the ethics of everyday clinical practice.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Hypatia’s Daughters: Fifteen Hundred Years of Women Philosophers ed. by Linda Lopez McAllisterSue M. WeinbergLinda Lopez McAllister, editor. Hypatia’s Daughters: Fifteen Hundred Years of Women Philosophers. Bloomington and Indianapolis: Indiana University Press, 1996. Pp. xiv + 345. Cloth, $49.95. Paper, $22.50.Hypatia: born in the fourth century A.D.: philosopher, mathematician, astronomer, teacher; brutally murdered in Alexandria in 415 A.D—whether for holding religious views regarded as heretical or because she (...) was a woman who dared to be a scholar and teacher remains a matter of speculation. Today, she gives her name to the journal for feminist philosophy. She is a symbol for those women who, over the centuries, have struggled to be part of the philosophical life of their time.Until very recently, the centuries that separated Hypatia from the present were assumed to have been a philosophical desert for women. But times have changed. Hypatia’s Daughters is a sign of this change. It contains eighteen articles on seventeen philosophers: Hypatia; Hildegard of Bingen, Heloise, and Christine de Pisan from the Middle Ages; Elizabeth of Bohemia, Sor Juana de la Cruz, Anne Conway, Damaris Masham, Catharine Trotter, Belle van Zuylen and Mary Wollstonecraft from the seventeenth and eighteenth centuries; Anne Doyle Wheeler and Harriet Taylor Mill from the nineteenth; Charlotte Perkins Oilman, Edith Stein, Hannah Arendt, and Angela Davis from the late nineteenth century into contemporary times. Few are known as well as they deserve, but many names are familiar even to non-specialists. Their ideas, however, are another matter.The collection in no way constitutes a definitive selection of women philosophers; those discussed are not presented as the most significant women philosophers in the history of philosophy. (A different kind of study would be necessary for evaluations of that kind.) The women here studied have little in common as a group; they wrote on many topics of philosophical concern; their views and their supporting reasoning differ. Further, as the subjects of the articles differ in their ideas, so do the contributors’ approaches and their methods of studying those ideas differ. These differences are the strengths of a collection that is stimulating, enlightening, provocative. The following examples indicate their range.Andrea Nye examines the correspondence of Heloise and Abelard and, in a second article, of Elizabeth of Bohemia and Descartes. Heloise and Elizabeth are usually regarded as passive followers or, at best, no more than serious questioners seeking answers of their correspondents. Nye’s fresh look at the Heloise-Abelard correspondence finds not only important differences between two ways of thinking, but also sees already underlying their disagreement what she calls the “macroquestion” of philosophy’s future: philosophy as “a professional discipline independent of political or social concerns or... an ongoing critical and cultural discourse.” (25) Elizabeth’s persistent questions to Descartes reveal ideas that challenge his views, especially on moral issues and physiological-psychological [End Page 164] phenomena; these are views that have a greater complexity than the basic issue of mind-body interaction that is usually identified as central to their exchange.Writing on Harriet Taylor Mill, Jo Ellen Jacobs examines changing attitudes towards her subject, beginning with views of Taylor Mill’s contemporaries and moving through the decades into our time. She finds parallels between criticisms of Taylor Mill and attitudes towards the so-called intellectual woman. In times encouraging of women, Taylor Mill is regarded as having made important contributions to the development of J. S. Mill’s thinking, in addition to writing and speaking about her own ideas and positions that did not always follow those of J. S. Mill. In less encouraging times, her significance tends to be minimized.Hannah Arendt is not usually thought of as a feminist. Joanne Cutting-Gray, through her discussion of Arendt’s early book on Rahel Varnhagen, develops implications of that study for Arendt as a “feminist thinker,” in particular through her focus on “the politics of alterity.” Cutting-Gray finds in the Varnhagen biography “an analogy between Jewish and female alterity [that] can stretch our understanding of women and politics.” (281)And there is more, much more: Martha Brandt Bolton’s scholarly examination of the philosophical works...

A highly ordered universe is described in terms of neutrino and electrino alone as basic particles, and length and time alone as dimensional units. New theories are obtained of particles, nuclides, atomic spectra, general relativity, and gravitation.

This paper provides a description of the role of the clinical ethicist as it is generally experienced in Canada. It examines the activities of Canadian ethicists working in healthcare institutions and the way in which their work incorporates more than ethics case consultation. The Canadian Bioethics Society established a Taskforce on Working Conditions for Bioethics (hereafter referred to as the Taskforce), to make recommendations on a number of issues affecting ethicists and to develop a model role description. This essay carefully (...) assesses this model role description. (shrink)

Based on a theory of primitive particles presented in two earlier papers, further applications to macro- and microphenomena are considered—for example, weather phenomena, earthquakes, photoemission, collision of particles, violation of parity, and decay modes. A broad class of leptons withSU(3) symmetry is proposed, together with a quarkless model of particles.

Considered together, Butler and Whitehead draw from a wide palette of disciplines to develop distinctive theories of becoming, of syntactical violence, and creative opportunities of limitation. The contributors of this volume offer a unique contribution to and for the humanities in the struggles of politics, economy, ecology, and the arts.

Let HF be the collection of the hereditarily finite well-founded sets and let the primitive language of set theory be the first-order language which contains binary symbols for equality and membership only. As announced in a previous paper by the authors, "Truth in V for ∃*∀∀-sentences is decidable," truth in HF for ∃*∀∀-sentences of the primitive language is decidable. The paper provides the proof of that claim.

E=mc 2 is found to be a special case ofE=σ ±1cn, where σ is any one of four susceptibilities, namely electric, magnetic, gravitational, and elastic. Letl be length,t time,Δt time dilation, andΔl a measure of Fitzgerald-Lorentz contraction. A particle is stated to be the manifestation of a collection of susceptibilities which arise when(Δl)/1=(Δt)/t. Then(ΔE)/E=5 (Δt)/2t=±(Δσ)/σ. Corresponding to susceptibility, special energy particles are postulated which exhibitSU(3) symmetry, Related to the susceptibilities are five new Heisenberg uncertainty relations. Three new conservation laws for (...) particles are proposed. (shrink)
