Skeletal identification using the frontal sinus region: a retrospective study of 39 cases

The importance of identification using the frontal sinus has been previously demonstrated in case reports. In this study, 39 cases of identification using frontal sinus comparison from the Ontario Chief Coroner's Office were reviewed and differences between antemortem and postmortem radiographs examined. All cases involved decedents older than twenty years. Three cases were rejected due to poor antemortem and postmortem film quality. One subject had no frontal sinus. Thirty-five cases provided conclusive postmortem to antemortem pattern matches. Sixteen cases also yielded metric (quantitative) matches. Duration between antemortem and postmortem radiographic examinations, age, gender, and cause of death did not affect the ability to obtain a match. This is the largest study undertaken on actual cases and demonstrates the validity of frontal sinus pattern matching for forensic identification.     

The Engine Room of Instruction: Small Group Teaching

The changing role of tutorials and tutors in an age of mass higher education is sketched. The differing purposes of small group teaching are explored; small groups are shown to have a variety of academic and pastoral functions. The mechanics of tutorial organisation are explored and the range of teaching formats examined.     

Utility maximizing bureaucrats: The bureaucrat's point of view

In this paper we develop a model to examine the extent to which bureaucrats are maximizing their own utility. In the spirit of Williamson (1964) and Simon (1957), we assume that bureaucrats are utility maximizers but not necessarily cost minimizers and we investigate how well the bureaucrat is doing in relation to his own goals. First, we hypothesize a utility function for the bureaucrat — we assume that the bureaucrat gains utility from producing municipal services as well as from hiring additional labor and capital. Then, using the concept of money metric utility, we determine the minimum expenditure necessary to achieve the same level of utility actually observed. Secondly, we determine the bureaucrat's distance from the utility maximizing choice of resources for a given level of expenditure. Finally, using a sample of public sector bureaucrats we attempt to explain the variation in wasted expenditure across municipalities and why bureaucrats might be underutilizers of each input relative to their own utility maximizing point.     

Race,Interracial Families,and Political Advertising in the Obama Era: Experimental Evidence

Across two studies of race and interracial families in political advertising, this article finds that significant benefits accrue to Black candidates who present themselves as part of interracial families. These findings suggest Black candidates are more likely to succeed when they engage in displays of “racial novelty,” or counter-stereotypical behavior, provided that behavior signals closer affinity to White voters. For Study 1, we tested four original advertisements for a fictitious political candidate, in which we varied only the candidate’s race and the race of his son. The Black candidate with the White son prevailed over all other combinations, with respondents finding him the most trustworthy, most qualified for office, most likely to share their values, and most likely to care about people like them. For Study 2, we tested four new original advertisements for a fictitious Black candidate, varying only the candidate’s profession and the race of his son. We find, again, that Black candidates who display non-Black children do significantly better than Black candidates who display racially homogeneous families. However, we observe much more modest benefits for a Black candidate who practices a racially novel profession. We view these results as demonstrating that Black candidates are more likely to reap the rewards of racial novelty only when they are willing to provide a personal, rather than professional, signal of their affinity for Whites. As Study 2 shows, White voters in particular are responsive to personal (rather than professional) demonstrations of racial novelty. This affirms the logic of “New Racism,” whereby Blacks are looked favorably upon if they exhibit behavior associated with Whites, but penalized otherwise.
