Biobanks are currently archiving human materials for medical research at a hitherto unprecedented rate. These valuable resources will be essential for developing ‘personalized’ medicines and for a better understanding of disease susceptibilities. However, for such scientific advances to benefit everyone, it is crucial that biobanks recruit donations from all sections of the community. Unfortunately, other initiatives, such as transplant programmes, have clearly demonstrated that ethnic minorities are under-represented. Here we suggest that this issue deserves serious consideration to avoid biobanks evolving (...) into ethnically biased archives which unwittingly promote race-specific research. Specifically, this necessitates research ethics committees engaging in a re-assessment of the relative merits of individual personal sovereignty and the common good. (shrink)

Few cross-national studies have been conducted on academic dishonesty. The aim of this study was to explore students’ disclosed levels of academic dishonesty between New Zealand and Nigeria. The measures obtained included incidence, acceptability, and justification of dishonest action. It was hypothesized that there would be differences between the two groups and that differences could be explained in terms of deontology, cultural relativism, utilitarianism, rational fair exchange, and/or response bias. There were 844 medical and health science students who participated in (...) the study and completed a questionnaire that explored incidence, acceptability, and justification of dishonest action. A binary logistic regression revealed that age and incidence were significant predictors of country allocation. Nigerian students reported more engagement in dishonest behaviors, and it is argued that these students have diverse cultural expectations, language variances, response strategies, norms, beliefs, and values. Educational interventions are essential to address concerns related to academic dishonesty such as promoting cross-cultural discourse, providing study skills programs, utilizing peer mentoring, creating formal exchange strategies, and endorsing honor codes.

One of the key learning objectives in any health professional course is to develop ethical and judicious practice. Therefore, it is important to address how medical and pharmacy students respond to, and deal with, ethical dilemmas in their clinical environments. In this paper, we examined how students communicated their resolution of ethical dilemmas and the alignment between these communications and the four principles developed by Beauchamp and Childress. Three hundred and fifty-seven pharmacy and medical students (overall response rate=63%) completed a (...) questionnaire containing four clinical case scenarios with an ethical dilemma. Data were analysed using multiple methods. The findings revealed that 73% of the qualitative responses could be exclusively coded to one of the ‘four principles’ determined by the Beauchamp and Childress' framework. Additionally, 14% of responses overlapped between the four principles (multiple codes) and 13% of responses could not be coded using the framework. The subsequent subgroup analysis revealed different response patterns depending on the case being reviewed. The findings showed that when students are faced with challenging ethical dilemmas their responses can be aligned with the Beauchamp and Childress framework, although more contentious dilemmas involving issues of law are less easily categorised. The differences between year and discipline groups show students are developing ethical frames of reference that may be linked with their teaching environments and their levels of understanding. Analysis of these response patterns provides insight into the way students will likely respond in ‘real’ settings and this information may help educators prepare students for these clinical ethical dilemmas.

We introduce a dynamic model for evolutionary games played on a network where strategy changes are correlated according to degree of influence between players. Unlike the notion of stochastic stability, which assumes mutations are stochastically independent and identically distributed, our framework allows for the possibility that agents correlate their strategies with the strategies of those they trust, or those who have influence over them. We show that the dynamical properties of evolutionary games, where such influence neighborhoods appear, differ dramatically from (...) those where all mutations are stochastically independent, and establish some elementary convergence results relevant for the evolution of social institutions.

Patient centred diagnosis is best practised through shared decision making; an iterative dialogue between doctor and patient, whichrespects a patient’s needs, values, preferences, and circumstances. -/- Shared decision making for diagnostic situations differs fundamentally from that for treatment decisions. This has important implications when considering its practical application. -/- The nature of dialogue should be tailored to the specific diagnostic decision; scenarios with higher stakes or uncertainty usually require more detailed conversations.
