Adolescent depression: Why more girls?

Although there has been evidence for some time of a sex difference in depression, relatively little research has examined the developmental process by which women come to be at greater risk than men for depression. In this paper, the developmental pattern of depressed affect is examined over early and middle adolescence, with a special focus on the patterns of boys as compared to girls. In addition, a developmental model for mental health in adolescence is tested for its power in explaining the emergence of gender differences in depression. Longitudinal data on 335 adolescents randomly selected from two school districts were used to test the hypotheses. Results revealed that girls are at risk for developing depressed affect by 12th grade because they experienced more challenges in early adolescence than did boys. The sex difference in depressed affect at 12th grade disappears once early adolescent challenges are considered.This research was supported in part by grants MH30252/38142 to A. Petersen.

The Federal Solution: Assessment and Prognosis for Nigeria and Africa

Federalism has not been a resounding success in Africa, althoughunitary regimes have had no better record One promising politicalsystem has been the consistently federal and periodically democraticgovernment of Nigeria. The principal challenges facing Nigeria,which are not unlike those facing other heterogeneous Africancountries, are national unity, democratic politics, and socioeconomicdevelopment. Examined here are the nature of these challenges,Nigeria's responses, potential alternatives, and possible implicationsof Nigeria's experience for federal democracy in Africa.     

Boundary Revisions: the Deconstruction of Moral Personality in Rawls, Nozick, Sandel and Parfit

The boundaries between selves and within selves are notions that have been subject to constant readjustment in the debates between liberals and communitarians. Through the archetype theories of Rawls, Nozick, Sandel and Parfit this essay re-enacts the deconstruction of one of the intuitive certainties of earlier liberal thought. Counterintuitive alliances are struck across the liberal-communitarian divide in demonstrating that the impersonality required by any theory of justice puts pressure on every notion of personality within it. Parfit radicalizes the problem of identity for everyone, permitting us to view old problems from new perspectives.     

Swings and gerrymanders

It is usual for electoral analysts to calculate the swing necessary at the next election to unseat a government, assuming that the swing is a uniform one. However, swings are not uniform. The non-uniform swing which would, on average, unseat a government is shown to be different from the uniform swing. For example, at the next Australian election for the House of Representatives, a uniform swing of 1.5 per cent against the current government would cause it to lose five seats, leaving it in a minority of 73 out of 148 seats, but a non-uniform swing of only 0.8 per cent would, on average, have the same effect. Implications of this variability for the size of the majority, the possibilities of a Parliament with an even number of seats being equally-divided, and the use of this analysis to detect gerrymandering and to correct for it, are considered.
