Two Lagrangians L and L′ are equivalent if the equations of motion derived from them have the same set of solutions. In that case, a matrix Λ may be defined which has the property that the trace of any analytic function of Λ is a constant of the motion. We extend this trace theorem to the case of classical field theory and discuss some of the implications for quantum theory and for procedures for finding equivalent Lagrangians.

This article explores egg freezing experiences of women in Turkey. Since 2014, it has been legal in Turkey to use egg freezing technology for ageing women, while it was previously allowed only for disease-related purposes. In cooperation with a private fertility clinic in Istanbul, the authors conducted 21 interviews with older, single women who held either professional or managerial positions and who were undergoing or had undergone the procedure. Drawing on a qualitative analysis of these interviews, the authors explore the (...) social context in which women postpone motherhood and decide to freeze their eggs. The study also looks at the women’s emotional responses to ageing that were triggered by the experience of egg freezing and their narratives of empowerment as a result of the procedure. (shrink)

Background and objective: Code status discussions may fail to address patients’ treatment-related goals and their knowledge of cardiopulmonary resuscitation (CPR). This study aimed to investigate patients’ resuscitation preferences, knowledge of CPR and goals of care. Design, setting, patients and measurements: 135 adults were interviewed within 48 h of admission to a general medical service in an academic medical centre, querying code status preferences, knowledge about CPR and its outcome probabilities and goals of care. Medical records were reviewed for clinical information (...) and code status documentation. Results: 41 (30.4%) patients had discussed CPR with their doctor, 116 (85.9%) patients preferred full code status and 11 (8.1%) patients expressed code status preferences different from the code status documented in their medical record. When queried about seven possible goals of care, patients affirmed an average of 4.9 goals; their single most important goals were broadly distributed, ranging from being cured (n = 36; 26.7%) to being comfortable (n = 8; 5.9%). Patients’ mean estimate of survival to discharge after CPR was 60.4%. Most patients believed it was helpful to discuss goals of care (n = 95; 70.4%) and the chances of surviving inhospital CPR (n = 112; 83.0%). Some patients expressed a desire to change their code status after receiving information about survival following inhospital CPR (n = 11; 8.1%) or after discussing goals of care (n = 2; 1.5%). Conclusions: Doctors need to address patients’ knowledge about CPR and take steps to avoid discrepancies between treatment orders and patients’ preferences. Addressing CPR outcome probabilities and goals of care during code status discussions may improve patients’ knowledge and influence their preferences. (shrink)

We describe the development, testing, and formative evaluation of nine role-play scenarios for teaching central topics in the responsible conduct of research to graduate students in science and engineering. In response to formative evaluation surveys, students reported that the role-plays were more engaging and promoted deeper understanding than a lecture or case study covering the same topic. In the future, summative evaluations will test whether students display this deeper understanding and retain the lessons of the role-play experience.

Success in sport can provide a source of national pride for a society, and vast financial and personal rewards for an individual athlete. It is therefore not surprising that many athletes will go to great lengths in pursuit of success. The provision of healthcare for elite sports people has the potential to create many ethical issues for sports doctors; however there has been little discussion of them to date. This study highlights these issues. Respondents to a questionnaire identified many ethical (...) matters, common to other areas of medicine. However they also raised problems unique to sports medicine. Some of these ethical difficulties arise out of the place of the sports doctor within the hierarchy of sport. Yet others arise out of the special relationship between sports doctors and individual players/athletes. This study raises some important questions regarding the governance of healthcare in sport, and what support and guidance is available to sports doctors. As medical and scientific intervention in sport escalates, there is a risk that demands for enhanced performance may compromise the health of the athlete, and the role the sports doctor plays remains a critical question.

Clinical decision making is a challenging task that requires practical wisdom—the practised ability to help patients choose wisely among available diagnostic and treatment options. But practical wisdom is not a concept one typically hears mentioned in medical training and practice. Instead, emphasis is placed on clinical judgement. The author draws from Aristotle and Aquinas to describe the virtue of practical wisdom and compare it with clinical judgement. From this comparison, the author suggests that a more complete understanding of clinical judgement (...) requires its explicit integration with goals of care and ethical values. Although clinicians may be justified in assuming that goals of care and ethical values are implicit in routine decision making, it remains important for training purposes to encourage habits of clinical judgement that are consciously goal-directed and ethically informed. By connecting clinical judgement to patients' goals and values, clinical decisions are more likely to stay focused on the particular interests of individual patients. To cultivate wise clinical judgement among trainees, educational efforts should aim at the integration of clinical judgement, communication with patients about goals of care, and ethical reasoning. But ultimately, training in wise clinical judgement will take years of practice in the company of experienced clinicians who are able to demonstrate practical wisdom by example. By helping trainees develop clinical judgement that incorporates patients' goals of care and ethical reasoning, we may help lessen the risk that ‘clinical judgement’ will merely express ‘the clinician's judgement.’.

Kurrâ’ya nispet edilen aynı kelimelerdeki edâ farklılıklarının tartışmalara sebep olmasından ötürü kıraat ihtilafı olan kelimelerde ihticâc yapılmasına gereksinim duyulmuştur. Delil getirmek manasında kullanılan ihticâc kavramı, kıraat ihtilafları için söz konusu olduğunda ise kıraat ihtilaflarının sıhhat zemininin ortaya konması kastedilmektedir. Ayrıca 2. asrın sonlarında kıraat tevcîhlerinin yapıldığı müstakil eserler ortaya çıkmakla birlikte kıraat alan yazınına ait genel telifatlarda da kıraat ihticâclarının yapıldığı görülmektedir. Kıraat müelliflerinden biri olan İbnu’l-Cezerî de Neşru’l-ḳırââti’l-‘aşr adlı eserinde zaman zaman kıraat ihticâcına yer vermektedir. Mezkûr eserdeki kıraat ihticâcları (...) hakkında tespit edilebildiği kadarıyla yapılmış tek bir çalışma bulunmaktadır. Fakat bu çalışmada, kıraatten ve bunun dışındaki disiplinlerden yeterince istifade edilmediği belirlenmiştir. Ayrıca selef ulemasının Neşru’l-ḳırââti’l-‘aşr adlı esere ihticâc konusunda etkisi özelinde bir çalışmaya da rastlanmamıştır. Buradan hareketle elinizdeki bu çalışmada, İbnu’l-Ce-zerî’nin kıraat ihticâcına dair uygulamaları Neşru’l-ḳırââti’l-‘aşr adlı eser özelinde incelenmiş, me‘âni’l-Kur’ân ve me‘âni’l-kıraat literatürlerinin ortaya çıktıkları dönem dikkate alınarak h. 2.-4. asırlarda kaleme alınan bu literatürlere ait eserlerin İbnu’l-Cezerî’ye ait kıraat tevcîhlerine etkisinin olup olmadığı araştırılmıştır. Çalışmanın neticesinde İbnu’l-Cezerî’nin yaptığı kıraat tevcîhlerinden ele alınanların bir kısmına, söz konusu üç asırda kaleme alınan me‘âni’l-Kur’ân ve me‘âni’l-kıraat telifatında ekseriyetle yer verilmediği saptanmıştır. İbnu’l-Cezerî’nin ise kıraat ihtilafının olmadığı yerlerde dahi ilgili edâ için ihticâc yaptığı müşahede edilmiştir. Buna ilaveten İbnu’l-Cezerî’nin Neşr’de yaptığı ihticâc uygulamalarının me‘âni’l-Kur’ân ve me‘âni’l-kıraat telifatında yapılan ihticâc işlemleriyle benzeştiği görülmüştür. Yine Neşr’in tevcîh eseri olmaması hasebiyle de İbnu’l-Cezerî tarafından yapılan ihticâcların ihtiyaç merkezli olarak kendini gösterdiği belirlenmiştir. (shrink)

This article shows under which circumstances fraudulent accreditation can occur in Brazilian military hospitals, calling attention to the tone at the top as a critical aspect of military fraud deterrence – and hence as a critical aspect of this branch of military ethics. The problems allegedly found in Brazilian military health institutions were revealed through in-depth interviews conducted with 29 professionals who reported to work or have worked in a Brazilian military hospital. These fraud allegations were mostly associated with false (...) documentation and procedures designed to give the appearance that legal requirements for accreditation were met and could be traced back to a weak or corrupt “tone at the top” coming from military higher ranks.

Prof. Flew's main purpose in God and Philosophy is ‘to develop and to examine a case for Christian theism’ . But in next to no time he shows his reader that here, as with the New York Commissioner for Air Pollution, ‘for’ really means ‘against’. For Flew's aim is to attack Christian theism and to develop the argument against it. One of his fellow-humanists rightly reviewed this book under the title ‘A Case for Atheism’. As the case for atheism is (...) being developed one quickly loses faith in the assurance that this ‘philosopher of religion has … no business to be counsel for either the prosecution or the defence’ and aspires to resemble most of all the examining magistrate . Soon we are told that an attack should and shall be launched against the heart of the quinta via of Aquinas . This is not just a slip of the pen for indeed the book contains a number of attacks on Aquinas. Of course Aquinas is not the only Christian theist who is attacked but he is Flew's chief individual target. (shrink)

Background: Discussions about medical errors facilitate professional learning for physicians and may provide emotional support after an error, but little is known about physicians’ attitudes and practices regarding error discussions with colleagues.Methods: Survey of faculty and resident physicians in generalist specialties in Midwest, Mid-Atlantic and Northeast regions of the US to investigate attitudes and practices regarding error discussions, likelihood of discussing hypothetical errors, experience role-modelling error discussions and demographic variables.Results: Responses were received from 338 participants . In all, 73% of (...) respondents indicated they usually discuss their mistakes with colleagues, 70% believed discussing mistakes strengthens professional relationships and 89% knew at least one colleague who would be a supportive listener. Motivations for error discussions included wanting to learn whether a colleague would have made the same decision , wanting colleagues to learn from the mistake and wanting to receive support . Given hypothetical scenarios, most respondents indicated they would likely discuss an error resulting in no harm , minor harm or major harm . Fifty-seven percent of physicians had tried to serve as a role model by discussing an error and role-modelling was more likely among those who had previously observed an error discussion .Conclusions: Most generalist physicians in teaching hospitals report that they usually discuss their errors with colleagues, and more than half have tried to role-model discussions. However, a significant number of these physicians report that they do not usually discuss their errors and some do not know colleagues who would be supportive listeners. (shrink)

Mehr et al.'s hypothesis that the origins of music lie in credible signaling emerges here as a strong contender to explain early adaptive functions of music. Its integration with evolutionary biology and its specificity mark important contributions. However, much of the paper is dedicated to the exclusion of popular alternative hypotheses, which we argue is unjustified and premature.

We review the equivalence of the two-flavor Skyrme-Witten model and the two-flavor large-N c quark model. The claimed equivalence for three flavorsbetween these two models is shown to be incorrectly given in the literature, and the properly equivalent extended three-flavor large-N c quark model is constructed and discussed.

Mucins are a family of high molecular weight, highly glycosylated glycoproteins found in the apical cell membrane of human epithelial cells from the mammary gland, salivary gland, digestive tract, respiratory tract, kidney, bladder, prostate, uterus and rete testis. Increased synthesis of the core protein and alterations in the carbohydrates attached to these glycoproteins are believed to play important roles in the function and proliferation of tumour cells. Aberrant glycosylation leads not only to the production of novel carbohydrate structures, but also (...) to the exposure of the core peptide. These novel epitopes may be candidates for diagnosis or therapy, by using either synthetic mucin fragments as vaccines, or monoclonal antibody‐based reagents which detect these structures. (shrink)
