Founder effect, drift, and adaptive change in domestic crop use in early Neolithic Europe

We document and quantify a significant reduction in crop diversity in the early central European Neolithic using a large multi-site database of archaeobotantical remains we compiled from published Neolithic sites across southwest Asia and Europe. Two hypotheses are proposed to account for the observed changes: one which claims that the different environmental conditions of central Europe selected for a different set of crop choices and strategies than in use in southeast and Mediterranean Europe; and a null hypothesis that explains the change as a drift process associated with a small founding population that subsequently undergoes rapid expansion. Through an agent-based simulation model, we test the null hypothesis and demonstrate that the drop in diversity exceeds that predicted by a drift process. We conclude by re-evaluating the possible adaptive changes underlying crop use in early Neolithic Europe.     

'The ravages of permissiveness': sex education and the permissive society

In this article we explore how sex education in schools has become an adversarial political issue. Although sex education has never been a wholly uncontroversial subject, we show that for two decades after the Second World War there was a broad consensus among policy-makers that it offered a solution to public health and social problems, especially venereal disease. From the late 1960s, this consensus came under attack. As part of a wider effort to reverse the changes associated with the 'permissive' society and legislation of the late 1960s, moral traditionalists and pro-family campaigners sought to problematize sex education. They depicted it as morally corrupting and redefined it as a problem rather than a public health solution. Henceforth, the politics of sex education became increasingly polarized and adversarial. We conclude that the fractious debates about sex education in the 1980s and 1990s are a legacy of this reaction against the permissive society.     

Timor-Leste and the discourse of state failure

The disorder in Timor-Leste in 2006, the collapse of the Alkatiri government, and the political crisis following the 2007 parliamentary elections have all fuelled speculation that the country is a potential ‘failing state’. After outlining the history of the latter concept, this paper examines the Timor-Leste case in relation to the phenomena associated with social and political instability. It has exhibited tensions between the civil regime and the military, apparently deepening ethnic/regional differences, weakness in governance institutions and a dependence upon state office as a means to wealth/power; all of these factors are associated with instability. In addition, some policy choices have fostered particular grievances. Timor-Leste's situation with reference specifically to the comparative literatures on ‘state failure’ and on ‘Africanisation’ is then reviewed. State failure literature suggests that regime type and executive recruitment and participation practices are crucial; as a new democracy hitherto dominated by a distinct political faction and facing vital electoral contests, the political system was bound to exhibit turbulence. However, Timor-Leste should be seen in a broader comparative context; accordingly though clearly at risk some caveats should be entered on the prospects for ‘failure’ of the Timor-Leste state. Timor Leste never having been the site of a fully functioning state, its politics more resemble Melanesia than Africa.
