ABSTRACT

In northern Laos and Northern Shan State in Myanmar, there has occurred a rapid expansion of rubber plantations, both by large economic concessions and by smallholder farmers. The impact of the introduction of rubber differs by place. This article analyses the impact of the introduction of rubber in two villages in Northern Shan State and two in Luang Namtha Province, Lao PDR. We differentiate vulnerability and precarity while assessing the changes that women and men have experienced, which allows us to problematise the long-term vulnerability of seemingly well-adapted farming households. We argue that the strategies that farmers have chosen to improve their situation today will lead to unsustainable livelihoods in the long term. We also link the analysis of vulnerability and precarity to changes in household gender relations. Notwithstanding increased precarity, rising household cash incomes and external support have improved women’s position in some places while hardly affecting gender relations in others.  相似文献

d-3-Methoxy-17-methylmorphinan (Dextromethorphan, DXM), which is a structural analog of morphine and codeine, has been widely used as a non-narcotic antitussive agent. It is a safe drug in therapeutic dose and does not produce analgesic effects, while its enantiomer, l-3-methoxy-17-methylmorphinan called levomethorphan (LXM) is a potent narcotic analgesic. DXM has been widely abused in Korea due to its hallucinogenic effect in large doses; therefore, the health authorities have regulated its use as a psychotropic agent since 2003. As its abuse has been serious, a possibility that DXM would be smuggled into Korea has also increased. Moreover, it has been suspected that there was the possibility of the adulteration or substitution of DXM with LXM due to their chemical similarities. Therefore, it was necessary for us to establish the enantiomeric separation of DXM and LXM. In this study, a liquid chromatographic method using a chiral column capable of separating stereoisomers of DXM as well as analyzing the major metabolites of DXM, 3-methoxymorphinan, 3-hydroxymorphinan, and 17-hydroxymethylmorphinan was developed. The validation of a method was studied through repeatability of retention times. Using this method, 32 confiscated DXM samples were analyzed to identify the enantiomers of DXM. As a result, DXM was detected in all samples and there was no evidence of the adulteration or substitution of DXM with LXM. Nevertheless, the stereochemical analysis of DXM and LXM is important not only to identify starting materials for illegal drug manufacture but also to understand the trends of abused drugs.  相似文献

This study provides the first systematic research of homicide-suicide (HS) in a Chinese society. Data were drawn from the HK Homicide Monitoring Data-base computer file derived from investigation and death reports held by the HK Police Force and the Coroner's Court. During the 10-year study period, 56 events involving 133 deaths were identified. The majority of offenders were males (75%) and most victims were female (64%). The mean age of offenders and victims were 41.9 and 32.3 years, respectively. Spouses and lovers comprised the majority of victims (46.4%) followed by child victims (36%). Most HS events were motivated by separation or termination of marital or sexual relations (39%), economic reasons (25%) and other domestic disputes (20%). The most frequent modes of killing were strangulation/suffocation (26%), stabbing/chopping (24%), followed by gassing/poisoning (14%) and falling from height (14%). The commonest of suicide was falling from height (48%). It was followed by gassing/poisoning (22%) and strangulation/suffocation (13%). Depression (18.3%) was found to be the commonest mental disorder. Most offenders were from low-socio-economic background. Two-third were unemployed and 76.6% had 9 or less years of education. HS in HK were distinguished from those reported in the western literature in respect to the high relevance of economic factors, the absence of mercy killing between old couples, a higher percentage of pedicide-suicides and the infrequent use of firearms.  相似文献

This article analyzes the effects of the transfer of Hong Kong's sovereignty to China in 1997 on the participation of Hong Kong and Taiwan in international organizations. It identifies the conditions under which China tolerates co‐existence with Taiwan as members of eleven intergovernmental organizations as of 1996. It concludes with two observations: one, international organizations are not monolithic entities; two, although China has overwhelming influence over Hong Kong's participation in these organizations, it depends also on how the Hong Kong Special Administrative Region government is going to manage its relations with China.  相似文献

Depressive symptoms and coping strategies of 161 Chinese adolescents were assessed and described using the Beck Depression Inventory (BDI) and the Ways of Coping Questionnaire (WCQ). Using the BDI cutoff scores of 9/10 and 29/30, respectively, over 64% of the adolescents would be in the depressed range, and 9% would be in the severely depressed range. For general depressive symptom level, Chinese adolescents appeared to have higher mean BDI score than U.S. adolescents and Chinese young adults. Their depressive symptom levels were found to relate to avoidant coping strategies as well as low self-es-teem and reduced social support. Implications for promoting adaptive coping, peer support network, and self-esteem enhancement were discussed.This study was supported in part by a Chinese University of Hong Kong UPGC direct grant for research.Received Ph.D. from the University of Western Ontario in 1978. Research interests include self-esteem, stress, coping, health, and psychopathology.  相似文献

Race-based remedies often are justified by evidence of prior discrimination. They work when they benefit groups previously disadvantaged. This article examines one such remedy—minority business set-asides—and its application in the award of public procurement and construction contracts by the state of New Jersey. Analyzed are contract awards to minority and non-minority/non-women-owned business enterprises in 1990, as well as in periods before, during, and after the imposition of a state minority set-aside program. Using a conventional decomposition approach, the article reveals significant discriminatory gaps in the success of minority- versus non-minority-owned firms in obtaining contracts from the state of New Jersey. The analysis suggests that minority contracting success rates fell from the pre-set-aside era to the set-aside era and that discriminatory outcomes persisted. The particular remedy chosen—while justified based on evidence of prior discrimination—appears not to have reduced the original discrimination nor did it unambiguously benefit minority businesses.  相似文献

Like many other places in the world, Hong Kong has drink–driving legislation which prohibits a driver from having in his blood alcohol exceeding a prescribed limit while in control of a motor vehicle. The accuracy of measuring this alcohol concentration is obviously of prime concern as an erroneous result can avert the administration of justice. The common practice is to deduct all errors from the measured value and compare the deducted value with the prescribed limit, so that the benefit of all errors of the measurement is given to the driver. It is therefore important for any laboratory responsible for measuring blood alcohol concentrations to identify and quantify all errors associated with the measurement. The present study examined 900 blood alcohol determinations carried out by the Hong Kong Government Laboratory (HKGL) on cases of suspected drink driving. The determinations were performed by 5 different analysts with two different sets of instruments during 1995–1997. Statistical analysis indicated that the instruments had no bearing on the random error or variability and that even though analyst was a significant factor on variability, the deviation from the mean so caused was only 0.3% and of no practical significance. When the systematic error introduced by the tolerance limits of the certified alcohol standards (purchased from the Laboratory of Government Chemists, UK) was taken into account, the total uncertainty (random plus systematic errors) of an alcohol determination at 99.5% confidence level was found to be 4%. It is recommended that laboratories engaged in blood alcohol determination should adopt similar statistical treatment of their analytical results to find out the error and to ensure that the results are independent of analyst and instrument used.  相似文献

Standard models of bureaucratic control argue that politicians vulnerable to asymmetric information rely on third‐party monitoring to expand information supply. This solution to information asymmetry assumes that politicians can process all information that comes their way. However, advocates strategically oversupply information to crowd out rivals, making such a solution counterproductive. Using data on administrative reorganization in Hong Kong, we examine the alternative proposition that bureaucratic control is contingent not only on how information is obtained but also on how it is processed under two different institutional arrangements: one that splits attention across domain‐specific streams and one that concentrates attention in a single sequence. In both cases, bureaucrats refrain from major changes when politicians break from these arrangements. Moreover, bureaucratic action is significantly more likely to respond to changes in attention allocation when politicians process information in multiple streams.  相似文献
