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.

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.

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 forty-five 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. The chapters include exceptional accounts of democracy in ancient Greece and Rome, modern Europe and America, among peoples’ movements and national revolutions, and its triumph since the end of the Cold War. However, this book also includes alternative accounts of democracy’s history: its origins in prehistoric societies and early city-states, under-acknowledged contributions from China, Africa and the Islamic world, its familiarity to various Indigenous Australians and Native Americans, the various challenges it faces today in South America, Eastern Europe, the Middle East and Asia, the latest democratic developments in light of globalization and new technologies, and potential future pathways to a more democratic world. Understanding where democracy comes from, 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, freedom and with a say in the decisions that affect their lives.

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.

This paper critiques specific forms of classroom teacher effectiveness research. In doing so, the paper suggests that education policy-making deems and employs teacher effectiveness research as a promising and capable contrivance for the identification of ineffective classroom teaching practice. The paper engages with this policy debate by using a specific policy example from the Australian state of Victoria, the Victorian Department of Education and Early Childhood Development (DEECD) Blueprint for Government Schools (2003/2008). Moreover, the attention given to “teacher effectiveness” as the means by which school systems aim to reverse student under-achievement positions classroom teachers as the controlling authority over educational outcomes. Indeed, teacher effectiveness is the defining quality of a policy-making debate that at its core dispenses with broader considerations of possible influence thought to substantially affect the learning outcomes of public school students.

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.

This document reports on the results and findings of a national survey of Directors (or equivalent) of Teaching and Learning Centres at Australian universities. The respondent group included 31 out of the 38 Centres invited to participate, and was a highly representative sample of the generally recognised institutional groupings in Australian higher education. While there is wide variation in the characteristics of individual Centres, the richness of which can only be appreciated by exploring the results and findings in detail, a summary of the results is provided here in the form of a description of a mythical ‘average’ Australian university Teaching and Learning Centre.
