While the concepts of race and ethnicity have been abused historically, they are potentially invaluable in epidemiology and public health. Epidemiology relies upon variables that help differentiate populations by health status, thereby refining public health and health care policy, and offering insights for medical science. Race and ethnicity are powerful tools for doing this. The prerequisite for their responsible use is a society committed to reducing inequalities and inequities in health status. When this condition is met, it is irresponsible not to utilize these concepts.  相似文献

Aggressive pursuit of free trade agreements (FTAs) and customs unions (CUs) by major and minor trading powers alike challenges the conventional wisdom in favor of such pursuit – competitive liberalization. An equally plausible explanation for an active bilateral and regional trade agreement policy, one which effectively de-emphasizes multilateralism, may be competitive imperialism. The protection and enforcement of intellectual property rights is one area in which new provisions, going beyond multilateral rules, are being negotiated and written into FTAs and CUs. Such provisions may yield insights into which characterization of bilateralism and regionalism – competitive liberalization or competitive imperialism – is more apt.

1955年是尼泊尔外交关系史上具有重要里程碑意义的一年.在只有英、美、印、法四个建交国的情况下,尼泊尔国际交往史翻开了新的一页.这一重要的历史进程自然地同尼泊尔北部的伟大邻邦--1949年刚刚成立的中华人民共和国紧密地联系在了一起,中国此时也正处在外交关系的首个拓展期.1955年4月在万隆举行的亚非会议给尼泊尔代表团和由周恩来总理率领的中国代表团提供了一个开启探讨两国建立正式外交关系对话的良好机会.这一对话同年7月在尼泊尔首都加德满都继续进行.1955年8月1日,尼泊尔王室首席顾问萨达尔·贡加·曼·辛格和中国驻印度大使袁仲贤阁下分别代表本国政府签署了两国正式建立外交关系的协议书.袁仲贤阁下随后被中国政府任命为中国驻尼泊尔王国首任大使.中国成为第5个与尼泊尔建立正式外交关系的国家,尼泊尔是中国的第22个建交国.  相似文献

Domestic violence, a prevalent problem in India, saw an increase during the lockdown imposed to contain the spread of COVID-19. This article explores the factors associated with an increase in domestic violence incidents during COVID-19 by applying routine activity theory (RAT) framework. Data were drawn from the incidents of domestic violence reported in newspapers. Data was analyzed using content analysis and three major themes, i.e., three principle components of RAT—motivated offender, suitable target, and absence of capable guardian—were drawn. Findings reveal that sources of motivation in domestic violence perpetrators during the lockdown were alcohol and unemployment. The symbolic value that perpetrators associated with women, lower inertia, visibility, and accessibility to the perpetrators made women suitable targets of domestic violence. Lastly, shortage of police force and travel restrictions on formal and informal sources resulted in the absence of capable guardians. We conclude that changes in the routine activities of people during the COVID-19 lockdown provided more opportunities to the perpetrators of domestic violence.

Abstract

Rural producer associations are considered a potential community-driven solution to the problems of smallholder agriculture. This article evaluates the impact of organising female farmers into producer associations in Gujarat, India. The initiative provided training, information, access to inputs, risk mitigation, and market linkages. Over 18 months, the programme weakly increased members’ non-farm income and access to output markets. It had stronger impacts on members’ awareness and utilisation of financial services. Impacts were heterogeneous, varying by pre-existing socioeconomic conditions. These findings suggest that producer associations can lower transaction costs for smallholders, but that poverty alleviation may be a longer-term prospect.  相似文献

In recent years, there has been a notable increase in the number of reports on drug-facilitated sexual assault. Benzodiazepines are the most common so-called "date-rape" drugs, with flunitrazepam (Rohypnol) being one of the most frequently mentioned. The aim of this study was to determine whether flunitrazepam and its major metabolite 7-aminoflunitrazepam could be detected in hair collected from ten healthy volunteers after receiving a single 2 mg dose of Rohypnol using solid phase extraction and NCI-GC-MS. Such data would be of great importance to law enforcement agencies trying to determine the best time interval for hair collection from a victim of drug-facilitated sexual assault in order to reveal drug use. Ten healthy volunteers (eight women and two men, 21 to 49 years old) participated in the study. The following hair samples were collected from each volunteer: one before flunitrazepam administration, and 1, 3, 5, 14, 21, and 28 days after. In five volunteers, 7-aminoflunitrazepam was detected 24 h after flunitrazepam administration and remained in hair throughout the entire 28-day study period (0.6-8.0 pg/mg). In two cases, 7-aminoflunitrazepam appeared in hair 21 days after drug intake (0.5-2.7 pg/mg), and in two subjects 14 days later (0.5-5.4 pg/mg). In one volunteer, 7-aminoflunitrazepam was detected on day 14 and 21 but concentrations were below the quantitation limit. Flunitrazepam was detected in some samples but all concentrations were below the quantitation limit (0.5-2.3 pg/mg).  相似文献

Lipstick can be an important piece of evidence in crimes like murders, rapes, and suicides. Due to its prevalence, it can be an important corroborative evidence in crime reconstruction. The analysis of such evidence can provide an evidentiary link between the suspect, the victim, object, or the crime scene. We report the use of nondestructive ATR-FTIR spectroscopy combined with chemometrics for the classification of 10 brands of lipsticks with nine samples each. Chemometric method of partial least square-discriminant analysis (PLS-DA) has been employed to interpret the data and classify the samples into their respective classes. The PLS-DA model provides an AUC figure above 0.99 in all brands except one; for which it is slightly less at 0.94. We have also tested the traces of these lipstick samples on different substrates treating them as unknowns in the already trained PLS-DA model. 100% of the samples on nine substrates viz. a cotton, nylon, plastic, dry tissue, denim (blue jeans), wet tissue, nitrile gloves, white paper, and polyester were correctly attributed to their source brand. In conclusion, the results suggest that ATR-FTIR combined with the chemometrics is a rapid, nondestructive, and accurate method for the discrimination and source attribution of lipstick. This study has potential for use in actual forensic casework conditions.  相似文献
