Mitochondrial DNA offers unique insights into invasion history of the common starling

Mitochondrial DNA (mtDNA) can be a powerful genetic marker for tracing origins and history of invasive populations. Here, we use mtDNA to address questions relevant to the understanding of invasion pathways of common starlings (Sturnus vulgaris) into Western Australia (WA) and discuss the utility of this marker to provide information useful to invasive species management. Mitochondrial sequence data indicate two geographically restricted genetic groups within Australia. Evidence of dispersal from genetically distinct sources outside the sampled range of starlings in Australia suggests increased vigilance by management agencies may be required to prevent further incursions from widely separated localities. Overall, genetic diversity in Australia was lower than in samples from the native range. Within Australia, genetic diversity was lowest in the most recently colonized area in the west, indicating that demographic bottlenecks have occurred in this area. Evidence of restricted dispersal between localities on the edge of the range expansion (ERE) in WA and other Australian sampling localities suggests that localized control within the ERE may be effective in preventing further range expansion. Signatures of spatial and demographic expansion are present in mismatch analyses from sampling localities located at the ERE, but neutrality indices did not support this finding, suggesting that the former may be more sensitive to recent expansion. Additionally, mismatch analyses support the presence of admixture, which is likely to have occurred pre-introduction. We compare our findings with those from a microsatellite study of the same samples and discuss how the mtDNA analyses used here offer valuable and unique insights into the invasion history of introduced species.

Review : a history of intelligence and "intellectual disability"

In many respects, A History of Intelligence and Intellectual 'Disability' is a confronting work. At a literal level, it comprises eighteen chapters verging on a total of quarter of a million words, apart from twenty-two pages of primary and secondary sources. Many of its chapters are drawn from Chris Goodey's articles since the early 'nineties in such journals as Ancient Philosophy, Archiv für Geschichte der Philosophie, History of the Human Sciences, and Political Theory. However, he immediately warns us that such articles exist as a "more primitive form" (vii) of the current volume.

The Edinburgh companion to the history of democracy

Democracy has never been more popular. It is successfully practiced today in a myriad of different ways by people across virtually every cultural, religious or socio-economic context. The 45 original essays collected in this companion suggest that the global popularity of democracy derives in part from its breadth and depth in the common history of human civilization. It sets a benchmark as the first collection on the history of democracy to present lesser known examples, such as those of ancient China, medieval Islam, colonial Africa or today's Burma, alongside more familiar cases like Athens, the English Parliament, the French Revolution and Women's Suffrage.

Undersdtanding where democracy comes from, and where its greatest successes and most dismal failures lie, is central to democracy's project of inventing ways to address the need of people everywhere to live in peace and freedom and with a say in the decisions that affect their lives.

Separate and invisible : a carceral history of Australian islands

This article examines the history of four islands used for incarceration in Australia: the ‘secondary punishment’ of convicts on Norfolk Island; the management and quarantine of indigenous people on Palm Island; the quarantine of all new migrants and visitors on Bruny Island; and the incarceration of enemy aliens on Rottnest Island. Incarceration has been used throughout Australia’s history as a method of social and political control, targeting categories of people perceived to pose a threat to the racial composition, social cohesion, or national security of the Australian community. By providing a space both separate and invisible to the community, Australia’s carceral islands served as a solution to a recurring problem for a young nation apprehensive about the composition, durability and security of its community. The human consequences of incarceration could be devastating.

The natural history of self-harm from adolescence to young adulthood : a population-based cohort study

Background Knowledge about the natural history of self-harm is scarce, especially during the transition from adolescence to young adulthood, a period characterised by a sharp rise in self-inflicted deaths. From a repeated measures cohort of a representative sample, we describe the course of self-harm from middle adolescence to young adulthood.

Methods A stratified, random sample of 1943 adolescents was recruited from 44 schools across the state of Victoria, Australia, between August, 1992, and January, 2008. We obtained data pertaining to self-harm from questionnaires and telephone interviews at seven waves of follow-up, commencing at mean age 15·9 years (SD 0·49) and ending at mean age 29·0 years (SD 0·59). Summary adolescent measures (waves three to six) were obtained for cannabis use, cigarette smoking, high-risk alcohol use, depression and anxiety, antisocial behaviour and parental separation or divorce.

Findings 1802 participants responded in the adolescent phase, with 149 (8%) reporting self-harm, More girls (95/947 [10%]) than boys (54/855 [6%]) reported self-harm (risk ratio 1·6, 95% CI 1·2–2·2). We recorded a substantial reduction in the frequency of self-harm during late adolescence. 122 of 1652 (7%) participants who reported self-harm during adolescence reported no further self-harm in young adulthood, with a stronger continuity in girls (13/888) than boys (1/764). During adolescence, incident self-harm was independently associated with symptoms of depression and anxiety (HR 3·7, 95% CI 2·4–5·9), antisocial behaviour (1·9, 1·1–3·4), high-risk alcohol use (2·1, 1·2–3·7), cannabis use (2·4, 1·4–4·4), and cigarette smoking (1·8, 1·0–3·1). Adolescent symptoms of depression and anxiety were clearly associated with incident self-harm in young adulthood (5·9, 2·2–16).

Interpretation Most self-harming behaviour in adolescents resolves spontaneously. The early detection and treatment of common mental disorders during adolescence might constitute an important and hitherto unrecognised component of suicide prevention in young adults.
