Refusing consent to organ donation remains unacceptably high, and improving consent rates from family or next-of-kin is an important step to procuring more organs for solid organ transplantation in countries where this approval is sought. We have thus far failed to translate fully our limited understanding of why families refuse permission into successful strategies targeting consent in the setting of deceased organ donation, primarily because our interventions fail to target underlying cognitive obstacles. Novel interventions to overcome these hurdles, incorporating an (...) understanding of cognitive psychology and behavioral change therapy, may be beneficial. One potential intervention is to use the concept of nudge theory, where decision-making is influenced by encouraging positive reinforcement and indirect suggestion. Purposefully nudging families to given consent for organ donation by understanding, and then overcoming, their inherent cognitive biases is novel but also controversial. This article explores the roles of relatives in decisions about organ donation, how nudge theory translates to organ donation and discusses the arguments for and against its application. (shrink)
Ethical leadership matters in the context of organizational change due to the need for followers to trust the integrity of their leaders. Yet, there have been no studies investigating ethical leadership and organizational change. To fill this gap, we introduce a model of the moderating role of involvement in change. Organizational change and involvement in change are proposed as context-level moderators in the relationships of ethical leadership and work-related attitudes and performance. We employ a sample of 199 supervisor–subordinate pairs from (...) a wide variety of organizations. Results support a three-way interaction (ethical leadership, organizational change, and involvement in change) for performance and OCBs. Our results have important implications for organizational change since ethical leadership appears to complement follower involvement when change is happening. (shrink)
After recalling the rigorous mathematical representations in Relativity Theory (RT) of (i) observers, (ii) reference frames fields, (iii) their classifications, (iv) naturally adapted coordinate systems (nacs) to a given reference frame, (v) synchronization procedure and some other key concepts, we analyze three problems concerning experiments on rotating frames which even now (after almost a century after the birth of RT) are sources of misunderstandings and misconceptions. The first problem, which serves to illustrate the power of rigorous mathematical methods in RT, (...) is the explanation of the Sagnac effect (SE). This presentation is opportune because recently there have appeared many non sequitur claims in the literature stating that the SE cannot be explained by SRT, even disproving this theory or claiming that the explanation of the effect requires a new theory of electrodynamics. The second example has to do with the measurement of the one-way velocity of light in rotating reference frames, a problem about which many wrong statements appear in recent literature. The third problem has to do with claims that only Lorentz-like type transformations can be used between the nacs associated with a reference frame mathematically modeling of a rotating platform and the nacs associated with a inertial frame (the laboratory). We show that these claims are equivocal. (shrink)
In this paper we scrutinize the so called Principle of Local Lorentz Invariance (PLLI) that many authors claim to follow from the Equivalence Principle. Using rigourous mathematics, we introduce in the General Theory of Relativity two classes of reference frames (PIRFs and LLRFγs) which as natural generalizations of the concept of the inertial reference frames of the Special Relativity Theory. We show that it is the class of the LLRFγs that is associated with the PLLI. Next we give a definition (...) of physically equivalent reference frames. Then, we prove that there are models of General Relativity Theory (in particular on a Friedmann universe) where the PLLI is false. However our finding is not in contradiction with the many experimental claims vindicating the PLLI, because theses experiments do not have enough accuracy to detect the effect we found. We prove moreover that PIRFs are not physically equivalent. (shrink)
A training physician has his first interaction with a pharmaceutical representative during medical school. Medical students are often provided with small gifts such as pens, calendars and books, as well as free lunches as part of drug promotion offers. Ethical impact of these transactions as perceived by young medical students has not been investigated in Pakistan before. This study aimed to assess the association of socio-demographic variables with the attitudes of medical students towards pharmaceutical companies and their incentives.
