论职业活动的社会前提

人类的职业活动是在分工的前提下展开的,但是,进入后工业社会,情况发生了根本性的变化,人们的职业活动不再是以分工为前提的,而是以社会分群为前提的。职业活动的前提从分工到分群的变化,意味着对职业活动的科学认识需要根本性的视角转变。在社会治理职业活动中也是这样,对于作为后工业社会治理模式的公共管理需要从社会分群的角度来加以认识。     

TRAJECTORIES OF CRIME AT PLACES: A LONGITUDINAL STUDY OF STREET SEGMENTS IN THE CITY OF SEATTLE*

Studies of crime at micro places have generally relied on cross‐sectional data and reported the distributions of crime statistics over short periods of time. In this paper we use official crime data to examine the distribution of crime at street segments in Seattle, Washington, over a 14‐year period. We go beyond prior research in two ways. First, we view crime trends at places over a much longer period than other studies that have examined micro places. Second, we use group‐based trajectory analysis to uncover distinctive developmental trends in our data. Our findings support the view that micro places generally have stable concentrations of crime events over time. However, we also find that a relatively small proportion of places belong to groups with steeply rising or declining crime trajectories and that these places are primarily responsible for overall city trends in crime. These findings are particularly important given the more general decline in crime rates observed in Seattle and many other American cities in the 1990s. Our study suggests that the crime drop can be understood not as a general process that occurred across the city landscape but one that was generated in a relatively small group of micro places with strong declining crime trajectories over time.     

茯苓多糖对雏鸡细胞免疫活性的影响及其抗肿瘤作用

给 1日龄AA雏鸡经腹腔注射马立克氏病病毒 (MDV)强毒株 ( 0 .2mL/只 ) ,并从当日开始给试验组雏鸡以 3个剂量连续肌肉注射茯苓多糖 1周 ,分别于 7、14、2 8、4 2、5 6日龄取脾组织 ,制备脾细胞悬液 ,用ELISA法检测了雏鸡淋巴细胞转化率、NK细胞活性及M活性 ,并与对照组比较。结果表明 ,3个剂量均可显著提高雏鸡的淋巴细胞转化率、NK细胞活性及M活性 ,且中剂量组效果优于其他 2个剂量组。证实茯苓多糖能提高MDV强毒株感染雏鸡的细胞免疫活性 ,并具有抗肿瘤作用     

鲁迅留日期间的翻译活动研究

早在日本留学期间鲁迅就清醒地认识到翻译具有启迪思想、沟通文化的作用。他的翻译作品为传播被压迫民族的反抗之声、启迪国人思想作出了很大贡献。鲁迅这一阶段的翻译以间接翻译为主。这种根据中介本进行翻译的移译经历为其日后翻译路径观的形成奠定了重要的实践基础。

Community-based forensic child and adolescent mental health services in England,Scotland and Wales: a national mapping exercise

Aim: We sought to ascertain the current nature of specialist community mental health provision for young people presenting with risk of harm to others or involvement with the youth justice system in England, Wales and Scotland. Methods: Questionnaire-based survey. Results: Fifty-five services were contacted, 48 responded and 35 of these were found to be providing some form of community mental health provision to high-risk young people. Thirteen services provided comprehensive community forensic child and adolescent mental health (FCAMH) services, whilst the remainder offered more ad hoc clinical input. Amongst the comprehensive FCAMH services, staffing, function, commissioning arrangements and population served varied widely. Conclusions: There is patchy geographical provision of comprehensive community FCAMH services across England, Scotland and Wales with heterogeneous commissioning arrangements, staffing and function. Development of a national commissioning strategy for community FCAMH services is required to ensure that the complex needs of high-risk young people are adequately addressed.     

ESTIMATING INTERVENTION EFFECTS IN VARYING RISK SETTINGS: DO POLICE RAIDS REDUCE ILLEGAL DRUG DEALING AT NUISANCE BARS?*

This paper investigates the effectiveness of police raids in reducing drug dealing in and around nuisance bars. We examine effects of both dosage (number of raids) and duration (months) of the intervention, as well as the conditioning effects of land use and population characteristics in shaping the underlying risk levels of drug dealing in the target and surrounding areas. Results indicate that the police intervention suppresses levels of drug dealing during periods of active enforcement, but the effects largely disappear when the intervention is withdrawn. Also, the effects of the intervention are mediated by risk characteristics in target and surrounding areas. Target areas characterized by higher levels of risk are more resistant to intervention effects than those with lower levels of risk. Risk factors in nearby areas are also significant. Bars with high levels of risk arising from land uses in surrounding areas are easier to treat, while bars with high levels of population‐based risk in surrounding areas are harder to treat.
