Assessing professional behavior: yesterday, today, and tomorrow.

PURPOSE: The author interprets the state of the art of assessing professional behavior. She defines the concept of professionalism, reviews the psychometric properties of key approaches to assessing professionalism, conveys major findings that these approaches produced, and discusses recommendations to improve the assessment of professionalism. METHOD: The author reviewed professionalism literature from the last 30 years that had been identified through database searches; included in conference proceedings, bibliographies, and reference lists; and suggested by experts. The cited literature largely came from peer-reviewed journals, represented themes or novel approaches, reported qualitative or quantitative data about measurement instruments, or described pragmatic or theoretical approaches to assessing professionalism. RESULTS: A circumscribed concept of professionalism is available to serve as a foundation for next steps in assessing professional behavior. The current array of assessment tools is rich. However, their measurement properties should be strengthened. Accordingly, future research should explore rigorous qualitative techniques; refine quantitative assessments of competence, for example, through OSCEs; and evaluate separate elements of professionalism. It should test the hypothesis that assessment tools will be better if they define professionalism as behaviors expressive of value conflicts, investigate the resolution of these conflicts, and recognize the contextual nature of professional behaviors. Whether measurement tools should be tailored to the stage of a medical career and how the environment can support or sabotage the assessment of professional behavior are central issues. FINAL THOUGHT: Without solid assessment tools, questions about the efficacy of approaches to educating learners about professional behavior will not be effectively answered.     

Synthesis and bacterial mutagenicity of the cyclopenta oxides of the four cyclopenta-fused of isomers of benzanthracene

Many polycyclic aromatic hydrocarbons containing peripherallyfused cyclopenta rings are believed to be activated primarilyby epoxidation of the cyclopenta ring. The cyclopenta epoxidesof a series of four cyclopenta benzanthracene derivatives, benz[e]aceanthrylene-5,6-oxide,benz[j]ace-anthrylene-1,2-oxide, benz(l)anthrylene-1,2-oxideand benz[k]acephenaceanthrylene-4,5-oxide were synthesized fromtheir parent hydrocarbons by formation of the bromohydrin followedby dehydrobromination, and characterized by u.v. – vis,and ¹H n.m.r. spectroscopy and mass spectrometry. The mutagenicityof these compounds was investigated in the Ames plate incorporationassay with Salmonella typhimurium strain TA98. All the oxideswere active without exogenous metabolic activation (170–320His⁺ revertants per nanomole) and also toxic above 0.5 µg/plate.Addition of S9 protein did not increase, and generally decreased,the mutagenicity of the oxides, while toxicity was largely unchanged.These results are consistent with the postulated role of cyclopentaoxides as major contributors to the mutagenicity of the parentcompounds in the Ames assay.     

HUMAN LONGINGS AND MASCULINE TERRORS: MASCULINITY AND SEPARATION FROM MOTHER

ABSTRACT The paper explores two literary texts - Dostoevsky's novel Crime and Punishment and Euripides'play Bacchae - from the point of view of immature masculinity and the catastrophe that can follow if the boy fails to achieve a genuine separation from the maternal object. The author examines the masculine anxieties and defences that arise when the boy fails to work through the Oedipus complex and instead retreats to a dyadic relation with mother which excludes the father. This retreat involves a denial of reality and the creation of a paranoid world in which his own wishes to take possession of mother can be experienced by him as an intrusion by the mother into his own masculine identity and ultimately as castration by the mother. Attempts to resolve this threat to masculinity include the use of anal defences and tyrannical states of mind in the creation of a pseudo-masculinity.
The movement into the male Oedipus complex necessarily involves a psychological state in which the externality of the oedipal-object mother is continually in danger of being blurred by the shadow cast by the pre-oedipal mother. (Thomas Ogden 1992)
