液相色谱串联质谱检测鳗鱼中四种氟喹诺酮残留

建立了液相色谱/串联质谱法测定鳗鱼中恩诺沙星,环丙沙星,诺氟沙星,氧氟沙星的方法。对分离和检测这四种兽药残留的液相色谱条件、质谱条件、样品前处理方法等作了详细的研究。用乙腈萃取样品中的残留物,在氮气保护下将萃取液浓缩干,加流动相1.0mL溶解残渣,正己烷液液萃取,弃上层液,下层溶液用作液相色谱分析荧光检测或质谱检测。在鳗鱼样品中添加四种残留物,添加浓度分别为0.01,0.050和0.100mg/kg,平均回收率(n=6)在70￣84.3%之间,相对标准偏差为3.0%～6.3%。     

Assimilation as multiracialism: The case of Singapore's Malays

The myths of meritocracy and multiracialism ‘explain’ between them both the ‘fairness’ of the Singapore system and the subordinate role of the non-Chinese minority races. They also purport to assure the minorities that they enjoy full status as members of the nation-building project and that their cultural and religious mores are embraced and protected within its framework. Using the Malay minority as its case study, and arguing from archival, oral, official government and secondary sources, this paper argues that the Singapore systems of meritocracy and multiracialism have not been concerned primarily with intercommunal tolerance since the 1970s, but are now programmes of assimilation of the racial minorities into a Chinese-dominated society.     

史料引用致误原因分析

史料是史学研究的基础.但自古以来,由于种种原因,错误的或者事实模糊不清的史料很多,如果不作必要的考证鉴别,很难获得科学的研究成果.造成史料引用致误的原因是多方面的,归结起来主要有:(1)史料本身无误,由于没有正确理解原意或者标点不正确而致误;(2)史料本身无误,由于引用者推断不确而致误;(3)史料内容比较含蓄,由于引用者缺乏深入辨析而致误;(4)没有直接引用原书而致误;(5)因版本不善而造成史料的错误或脱漏;(6)史料本身就有错误.     

Gender,lineage, and fertility‐related outcomes in Ghana

A growing literature examines the empirical relationship between the joint reproductive preferences of marital partners and reproductive outcomes in Africa. Less explored is how spousal power in decision making may be influenced by lineage type. Using pooled data from Ghana, we investigate how lineage affects gendered reproductive decision outcomes and find some evidence that matrilineal women are more able than nonmatrilineal women to translate their reproductive preferences into action consistent with their goals.

Family Cap and Nonmarital Fertility: The Racial Conditioning of Policy Effects

Using an experimental design, this research examines the effect of the nation's first family cap on the births, abortions, and contraception use of over 8,000 women receiving public assistance in New Jersey. The family cap denies additional cash benefits to children conceived while the mother is receiving public assistance. Our research shows that a targeted welfare benefit manipulation does influence fertility behavior; however, the effect is conditioned by race. We find that Black women in the experimental group have a 21% lower birth rate and a 32% higher abortion rate than Black women in the control group. We do not find a birth effect for Hispanic or White women. We discuss the policy implications of the effects of a segmented family cap.     

Racial differences in urban neighboring

Despite mixed expectations generated by existing theories and evidence, this analysis documents clear racial differences in urban neighboring behavior. Using data from a survey of Nashville, Tennessee, residents, we show that blacks interact with their neighbors more often than whites do, and in a greater variety of ways. The only noteworthy similarity between the two groups is the positive impact of neighboring on feelings of community affect. Overall, our results support the view that neighbor relations — like other kinds of informal participation — have helped blacks cope with constrained social opportunities and provided them with access to resources unavailable through formal institutional channels.Revised version of a paper presented at the annual meeting of the American Sociological Association, San Francisco, August 1989.     

Young helpline callers and difference: exploring gender, ethnicity and sexuality in helpline access and provision

This article, which has its origin in a feasibility study carried out for three youth telephone helplines, focuses on gender, difference and helpline access by young people. During the research process the writers noted that for the three commissioning helplines, as is the case with the majority of other telephone helplines, approximately two‐thirds of callers are female. A helpline for young Muslims where the gender access ratio was 50/50 stood out as being different in this respect. Until recently, literature on gender and help‐seeking has tended towards making a blanket identification of males as experiencing difficulties in negotiating pathways to help. Although this difficulty of males is evident in relation to both help‐seeking and access to helplines, our study suggests that, at least in relation to helpline usage, when we take culture, ethnicity and sexuality into account, the help‐seeking situation may be more nuanced. This has implications in terms of enabling a cross‐section of young people to access helplines as well as with regard to helpline service development.     

Fuzzy K-means clustering models for triangular fuzzy time trajectories

We focus our attention on the classification of fuzzy time trajectories with triangular membership function, described by a given set of individuals. To this purpose, we adopt a fullyinformational approach, explicitly recognizing the informational nature shared by the ingredients of the classification procedure: the observed data (Empirical Information) and the classification model (Theoretical Information). In particular, by supposing that the informational paradigm has a fuzzy nature, we suggest three fuzzy clustering models allowing the classification of the triangular fuzzy time trajectories, based on the analysis of the cross sectional and/or longitudinal characteristics of their components (centers and spreads). Two applicative examples are illustrated.
