Abstract

This paper compares the reasons given by three South-east Asian states (Laos, Thailand and Vietnam) for choosing to suppress opium production. While external pressure, often from the US or United Nations (UN)/League of Nations, is the most commonly identified reason in the literature, and was experienced in each case, it was not by itself sufficient to motivate states into action. All three cases were motivated by religious or ideological opposition to drug consumption or trade, rural development, state extension and concern for increasing domestic drug consumption. Apprehension about rising drug consumption often possessed racial or chauvinistic elements. The development of export commodities, environmental protection and national security were also identified in one or two cases. The paper concludes by hypothesising that economic and/or security considerations underlie all choices to suppress illicit drug crops.  相似文献

Few studies have examined risk factors of childhood and early adolescent depressive symptomatology trajectories. This study examined self-report depressive symptomatology across a 6-year time period from 2nd to 8th grade to identify latent groups of individuals with similar patterns of depressive phenomena in a sample of 951 children (440 girls, 511 boys). Analyses, using semiparametric group modeling (SGM), identified 5 trajectory groups for girls and boys: low depressed stables, low depressed risers, mildly depressed stables, moderately depressed changers, and moderately depressed risers. Individual risk factors, with the exception of shy/withdrawn behavior, were significantly different across trajectory group membership for boys and girls, as was low-income status for boys. Boys in the low depressed and mildly depressed stable trajectory groups had significantly higher levels of antisocial behavior, attention problems, and lower social competency compared to girls in similar groups. These results suggest that universal prevention programs implemented in early elementary school that target selected risk factors may be helpful in reducing future adolescent mental health problems, specifically depressive symptomatology.  相似文献

The riskiness of state employee pension plan portfolios varies across states. We investigate whether this variation is related to how public employees and taxpayers share actuarial surpluses of pension accounts. We focus on two determinants of a plan’s asset mix: the relative influence of public employees to taxpayers; and whether a surplus-sharing contract is specified. Our theoretical model demonstrates that the effect of public employee influence on the asset mix is ambiguous. Our empirical results corroborate this complex theoretical result. In our theoretical and empirical analyses, if a surplus sharing rule is specified, plans adopt a more aggressive investment allocation.  相似文献

Much economic policy is deliberately shifted away from direct political processes to administrative processes—political pressure deflection. Pressure deflection poses a puzzle to standard political economy models which suggest that having policies to ‘sell’ is valuable to politicians. The puzzle is solved here by showing that incumbents will favor pressure deflection since it can deter viability of a challenger, essentially like entry deterrence. U.S. trade policy since 1934 provides a prime example, especially antidumping law and its evolution.  相似文献

Focusing on identity development explorations enables a greater understanding of contexts that affect immigrant adolescents. Utilizing thematic and grounded narrative analysis of 46 journal writings, during a one-month period, from first and second generation Vietnamese adolescents ranging in age from 15 to 18 (26 residents of a culturally and politically active ethnic enclave in Southern California; 20 adolescents living outside the enclave), this study establishes ways in which a focus on social context and exploration processes illuminates the complexity of immigrant adolescents’ identity formation. The two groups shared many similarities, including precipitants to exploration and steps undertaken to explore identity. However, two factors—social and cultural influences and emotional reactions—revealed interesting contrasts distinguishing enclave from non-enclave dwelling Vietnamese adolescents. Data also suggested that immigrant adolescents strive to integrate different domains of identity (ethnicity, gender, career) both with one another and with the historical, social, and cultural contexts they occupy.

This paper assesses the contribution of livestock to reducing rural poverty and examines the determinants of livestock assets with panel data from Vietnam. The findings show that livestock production contributes to reducing poverty and livestock assets are influenced by the number of shocks that households faced during the last three years, access to credits, farmland size, education of household head, irrigation system, and access to the national electricity. We suggest that empowering rural households to better cope with shocks contributes to developing livestock and consequently to reducing rural poverty.  相似文献

This paper examines gender discrimination using two novel perspectives: its relationship with personal face and its manifestation in contemporary Vietnam. Interviews with a sample of college teachers in Nha Trang city suggest that gender discrimination is reflected in and institutionalised through learning and enacting ‘acceptable’ face-related behaviours. These processes are exemplified in gender based linguistic conventions, role differentiation and segregation, the higher value associated with male roles, the (surface) acceptance of double standards by both genders and the recognition of public sanctions as effective reinforcers of gender inequality. Despite limitations in generalising from this research, an approach based on personal face-related language, behaviour and attitudes has promise for understanding how gender inequality functions at both individual and societal levels.  相似文献

Abstract

Professor Sir Alfred Zimmern, a highly prominent British commentator on international politics, was a notable visitor to Australia in 1938. Due to the critiques of EH Carr, Martin Wight and Hedley Bull, Zimmern became associated with the ‘utopian’ school of analysis of the inter-war period. In a stay lasting five weeks which coincided with the Munich crisis, his (now neglected) lectures and broadcasts were widely reported. Zimmern did not fully endorse the Munich agreement, which had been negotiated by British Prime Minister Neville Chamberlain and was supported by Australian Prime Minister Joseph Lyons. He was privately critical of Australian policy-makers. Despite Bull’s claim that Zimmern was a believer in progress and thus bound to discern the growth of order in international affairs, Zimmern’s analysis of the Munich agreement emphasized the return of power politics and the dangers of war. Further examination of his 1930s writings shows that such possibilities were not inconsistent with his broader analysis of international relations.  相似文献
