The notion of whether people focus on the past, present or future, and how it shapes their behaviour is known as Time Perspective. Fundamental to the work of two of its earliest proponents, Zimbardo and Boyd (2008), was the concept of balanced time perspective and its relationship to wellness. A person with balanced time perspective can be expected to have a flexible temporal focus of mostly positive orientations (past-positive, present-hedonistic, and future) and much less negative orientations (past-negative and present-fatalistic). This (...) study measured deviation from balanced time perspective (DBTP: Zhang, Howell, and Stolarski, 2013) in a sample of 243 mature adults aged 45 to 91 years and explored relationships to Retirement Planning, Depression, Anxiety, Stress, Positive Mood, and Negative Mood. Results indicate that DBTP accounts for unexplained variance in the outcome measures even after controlling for demographic variables. DBTP was negatively related to Retirement Planning and Positive Mood and positively related to Depression, Anxiety, Stress and Negative Mood. Theoretical and practical implications regarding balanced time perspective are discussed. (shrink)

Initiatives which offer support to primary care practitioners interested in research have become widespread in the UK. There has been little debate, however, about the ethical issues involved in such interactions with practitioners. Established codes of practice and analyses of the institutional and strategic contexts have been used to inform this discussion. The paper concludes with a recommendation that more explicit quasi-contractual relationships should be negotiated between those offering and those seeking help.

We report on the deliberations of an interdisciplinary group of experts in science, law, and philosophy who convened to discuss novel ethical and policy challenges in stem cell research. In this report we discuss the ethical and policy implications of safety concerns in the transition from basic laboratory research to clinical applications of cell-based therapies derived from stem cells. Although many features of this transition from lab to clinic are common to other therapies, three aspects of stem cell biology pose (...) unique challenges. First, tension regarding the use of human embryos may complicate the scientific development of safe and effective cell lines. Second, because human stem cells were not developed in the laboratory until 1998, few safety questions relating to human applications have been addressed in animal research. Third, preclinical and clinical testing of biologic agents, particularly those as inherently complex as mammalian cells, present formidable challenges, such as the need to develop suitable standardized assays and the difficulty of selecting appropriate patient populations for early phase trials. We recommend that scientists, policy makers, and the public discuss these issues responsibly, and further, that a national advisory committee to oversee human trials of cell therapies be established. **NB we did not reccommend a NAC, we think it might be appropriate**.

If stem cell-based therapies are developed, we will likely confront a difficult problem of justice: for biological reasons alone, the new therapies might benefit only a limited range of patients. In fact, they might benefit primarily white Americans, thereby exacerbating long-standing differences in health and health care.

The use of cost-benefit analysis (CBA) in environmental decision-making and the contingent valuation (CV) technique as input into traditional CBA to elicit environmental values in monetary terms has stimulated an extensive debate. Critics have questioned the appropriateness of both the method and the technique. Some alternative suggestions for the elicitation of environmental values are based on a social process of deliberation. However, just like traditional economic theory, these alternative approaches may be questioned on their implicit value judgements regarding the legitimacy (...) of the social-political organisation of the process of value elicitation. Instead of making assumptions a priori, research efforts should be focused on the processes by which actual public attitudes and preferences towards the environment can best be elicited and fed into environmental or other public policy decision-making. In the study presented in this paper, support was found for both the individual WTP based approach and a participatory social deliberation approach to inform the environmental decision-making process, suggesting that a combination of both approaches is most appropriate.

The two-point correlation functions of classical electromagnetic zero-point radiation fields are evaluated in four-vector notation. The manifestly Lorentz-covariant expressions are then shown to be invariant under scale transformations and under the conformal transformations of Bateman and Cunningham. As a preliminary to the electromagnetic work, analogous results are obtained for a scalar Gaussian random classical field with a Lorentz-invariant spectrum.

The Travail of Nature shows that the theological tradition in the West is neither ecologically bankrupt, as some of its popular and scholarly critics have maintained, nor replete with immediately accessible, albeit long-forgotten, ecological riches hidden everywhere in its deeper vaults, as some contemporary Christians, who are profoundly troubled by the environmental crisis and other related concerns, might wistfully hope to find. This is why it is appropriate to speak of the ambiguous ecological promises of Christian theology.

يتناول محمد حيان السمّان في كتابه في "تدبير القداسة: الحجابة والحجاب - أدب الدخول على السلطان في التراث العربي الإسلامي"، الصادر عن المركز العربي للأبحاث ودراسة السياسات، العلاقة بين السلطة السياسية والمجتمع في السياق العربي - الإسلامي، من خلال موضوع الحجابة والسلطان المحتجِب عن رعيته، والوقائع المتصلة بالقدوم على أصحاب السلطة من خلفاء وملوك وسلاطين ووزراء وغيرهم، وانتظار الإذن بلقائهم. يتألف الكتاب (407 صفحات بالقطع الوسط، موثقًا ومفهرسًا) من مدخل، وقسمين فيهما عشرة فصول. في المدخل، تأسيس وإضاءة، يعالج المؤلف مسألة (...) الحجابة والحاجب من حيث اللغة والاصطلاح، ومسألة الحجابة عند ابن خلدون من منطلق الحضارة الداعية إلى انتحال الألقاب وتمييزها، ومسألة الاستئذان الشرعي والحجابة والفرق بينهما.

Trataremos de acercarnos a la concepción clásico-cristiana de oíkois y téine a partir del planteo actual de la relación, tan problemática, de técnica y medio ambiente. Marcharemos, por tanto, en pos de la noción clásica, no sólo como quien busca en la antigüedad un par de términos epónimos, sino con la aspiración de hallar las formas modélicas que puedan inspirar la solución de una aguda crisis cultural. Esta crisis se caracteriza por la crispada relación establecida, en el mundo moderno, entre (...) el desarrollo tecnológico y el ámbito vital del hombre, su entorno, su "casa". Ante todo, es necesario observar que la técnica moderna no representa simplemente el último estadio de la téjne, como continuidad, en extensión e intensidad, del milenario esfuerzo del hombre por dominar a la naturaleza mediante el empleo de habilidades artesanales. Hay en la técnica moderna algo de absolutamente peculiar, de cualitativamente diverso. Debemos subrayar, por tanto, para alcanzar su plena comprensión, el calificativo de moderna: la téjne ha cambiado de sentido. No se trata ya de un fenómeno más de nuestro mundo, sino que ahora el mundo moderno puede ser calificado como mundo técnico; técnica es también la cultura propia de la modernidad. (shrink)
