Research on medical records without informed consent

Observational research involving access to personally identifiable data in medical records has often been conducted without informed consent, owing to practical barriers to soliciting consent and concerns about selection bias. Nevertheless, medical records research without informed consent appears to conflict with basic ethical norms relating to clinical research and personal privacy. This article analyzes the scope of these norms and provides an ethical justification for research using personally identifiable medical information without consent.     

Development perspectives: Views from rural Lebanon

This paper explores development issues from the perspective of two villages in rural Lebanon. Educated male villagers see themselves as initiators of development and use the same language as NGO officials. Client-patron relationships and wasta (the act of accessing material favours, such as development projects, from the powerful) are means for these men to achieve their political ends. Women and the less powerful men, who are not part of the wasta network, tend to be disregarded in decision making, but nonetheless have strong views about the needs of the villages. The Islamic view emphasises the moral life.     

Procedural bias in forensic science examinations of human hair

Several forms of expert forensic science evaluations exist that rely at least in part on the subjective opinion of the examiner. Human hair identification is one such examination. This paper considers possible sources of influence or bias that may be responsible for examiner errors. Data are reported of an experiment that compares the conventional examination procedure (known versus questioned samples) against an alternative procedure (a lineup of samples) designed to limit the influence of factors that contribute to error. The altenative procedure produced fewer incorrect conclusions (3.8%) than the conventional procedure (30.4%).
