论价值评价及其标准

价值评价是价值哲学的重要内容.价值评价作为一种特殊的认识活动,是评价主体将客体的属性纳入自己的头脑并运用主体的目的、需要和本质力量加以分析和改造的活动.它与一般的认知活动在对象、规则和目的上都存在着本质的差异.价值评价由于有主体的创造性、知识、情感和意志的参与,故其具有明显的主体性特征,同时,它也受着价值事实、主体需要和社会实践等客观性因素的制约.在价值评价过程中,评价的标准是合目的性和合规律性的有机结合,这两者统一的基础是实践,实践是价值评价的最高标准.

用杜仲叶、山楂、黄芪等中草药研制猪用饲料添加剂 ,对 4 0日龄断奶仔猪进行饲喂试验 ,观察其对断奶仔猪肠道菌群和生产性能的影响。试验结果表明 ,服用中药的 3组试验猪肠道中的乳酸菌和双歧杆菌均比对照组明显增高 (P <0 .0 5 ) ,而大肠埃希氏菌和肠球菌指数以及腹泻发生率则明显降低 ;日增重分别比对照组提高了 9.2 0 %、5 .5 0 %和 13.32 % ;料肉比分别比对照组降低了 9.80 %、6 .6 4%和 15 .0 3%。结果显示 ,该中草药饲料添加剂常规粉剂和提取物制剂均能促进仔猪肠道中有益菌的增殖 ,提高猪的生产性能。     

基于主成份分析法的警务信息化水平综合评价

公安机关正面临着信息化的挑战,需要科学的评价指标体系与评价方法来指导公安机关的信息化建设。建立包括信息网络基础建设、数据库建设、信息安全、管理制度规范化、公安人员信息素质五大类指标的警务信息化水平评价指标体系,应用主成份分析法对公安机关警务信息化水平进行多因素下的综合分析与评价,是一种合理的选择。     

反相高效液相色谱法同时测定人血清中氯丙嗪与氯扎平的浓度

作者建立了同时测定人血清中氯丙嗪与氯扎平浓度的反相高效液相色谱(RP—HPLC)法。以利眠宁为内标,用环己烷—乙醚(1:1)混合溶剂提取血清中氯丙嗪和氯扎平。高浓度中毒者血清(>1ug/ml)则用乙腈沉淀后直接进行色谱测定。血清中氯丙嗪、氯扎平的方法回收率乎均各为98.5±4.0(SD)%,CV4.2%;99.9±4.1(SD)%,CV4.1%。两药在血清中的最低检测浓度为10ng/ml。本法应用于临床氯丙嗪、氯扎平合用药物的血浓度监测及司法中毒案例的分析,结果满意。     

A spatial analysis of green teams: a tactical response to marijuana production in British Columbia

Over a period of 4 years (1997–2000), British Columbia (BC) experienced tremendous growth in the illicit production and distribution of domestically grown marijuana. By the close of 2000, each policing jurisdiction in BC had adopted a particular policy in response to grow operation proliferation. In summary, four policy responses were noted. First, some maintained the status quo wherein enforcement of police initiated investigations and citizens’ tips continued, but with no additional resources specifically dedicated to grow operations. Second, some jurisdictions suspended the majority of investigation and enforcement of grow operations. Third, some agencies implemented or reinforced existing resource intensive drug squads, which focused on trafficking, sales and production of all types of drugs. Finally, some of the jurisdictions formed specialized tactical units known as “green teams” that focused solely on the enforcement of marijuana production. In this paper, we evaluate the effectiveness of green teams using a Geographic Information System (GIS) and difference-in-difference estimates. The results indicate that green teams decrease grow operations within their target area without significant displacement to surrounding areas.

Can electronic monitoring reduce crime for moderate to high-risk offenders?

Electronic monitoring (EM) of offenders has been in use for just over two decades and motives for using it remain diverse. Some agencies that use EM attempt to deliver humane and affordable sanctions while others seek to relieve jail crowding or to avoid the construction of new jails. Nonetheless, all EM programs aim to suppress the criminal behavior of offenders being monitored and its advocates have always hoped EM could be instrumental in reducing long-term recidivism. This review investigates the history of EM and the extent to which EM empirically affects criminal behavior in moderate to high-risk populations. All available recidivism studies that included at least one comparison group between the first impact study in 1986 and 2002 were considered for the review. Although variants such as GPS tracking and continuous testing for alcohol in perspiration have recently emerged, no studies of these technologies were found that met the review’s inclusion criteria. Studies are examined and combined for meta-analysis where appropriate. Given its continued and widespread use and the dearth of reliable information about its effects, the authors conclude that applications of EM as a tool for reducing crime are not supported by existing data. Properly controlled experiments would be required to draw stronger conclusions about the effects of EM.     

Prevention science,drug abuse prevention,and Life Skills Training: Comments on the state of the science

There has been tremendous growth in the field of prevention science over the past two decades. The defining features of contemporary prevention science are high quality empirical research using rigorous and well-established scientific methods, careful hyphothesis testing, and the systematic accumulation of knowledge. One area where substantial progress has been made is in our understanding of the etiology and prevention of tobacoo, alcohol, and illicit drug abuse. In this paper, we review the growth in prevention as a scientific enterprise, discuss advances in drug abuse prevention research, and review the effectiveness of one approach to the problem of adolescent drug abuse, the Life Skills Traning (LST) program, and the methodological strengths of the LST evaluation research. In addition, we provide a response to criticism regarding two types of data analysis in evaluation research, and show that these analyses can help address a number of important research questions with implications for theory and practice. First, the analysis of high fidelity subsamples can address research questions about the importance of program implementation fidelity; and second, composite measures of concurrent tobacco, alcohol, and marijuana use (i.e., polydrug use) are useful in testing research questions about program effects on more serious levels of drug involvement. With an increasing number of ramdomized controlled trials underway, the field of prevention science is contributing to a new generation of evidence-based approaches and policies that, if widely utilized, offer the potential of reducing the mortality and morbidity associated with a number of major health and social problems.     

高校“音乐欣赏”选修课开设的几个问题

在高校教学过程中,选修课日益成为一道亮丽的风景,如何开设选修课以发挥其最大的教学功能,这是教育工作者普遍关注的问题.高校"音乐欣赏"选修课的开设一要明确教学目的,二要突破定向思维,三要设计课堂形式,四要增强师生交流.     

产权、人权与制度

产权的本质是一定社会关系下的劳动。产权与人权有统一性,产权既是人权的一种实现,又是人权的保障,二者都和超经济特权相对立。产权与人权还具有对立性,这种对立的实质是平等与效率、公正间的冲突。体现了科学发展观的制度评价标准即"人权-制度"标准,是人权与产权对立统一关系的均衡,它完全不同于西方正统经济学的狭隘效率观标准。"人权-制度"标准可以为我们构建有效的劳动力产权制度提供理论指导。
