从信访工作中存在的突出问题看和谐社会建设的难点重点

本报告力求以深入分析当前信访工作面临的形势、信访问题的成因及规律为切入点,探寻当代中国社会发展中存在的若干普遍性问题,揭示和谐社会建设的难点和重点问题,并为解决这些问题提出若干思路和对策。     

DNA指纹图在法医学鉴定中应用的研究(Ⅰ)

应用 MYO DNA 探针对中国人进行了 DNA 遗传指纹图检验。从两个家系16人及100个无关个体中取肘静脉血提取 DNA,用限制性内切酶 HinfⅠ或 HaeⅢ水解,1%琼脂糖凝胶电泳分离,经 Southern印迹转移,MYO DNA 探针杂交,获得了清晰可辨的 DNA 指纹图谱。结果每个个体在3.0Kb 以上均能检出10条以上杂交区带,个体间的相关概率<4×10~(-9),由杂交区带构成的图谱是个体特异的,杂交区带遵循孟德尔的显性遗传方式由亲代向子代遗传;具有 DNA Fingerprints 的特点。对两起亲子鉴定的案例进行指纹图检验,孩子所存在的杂交区带,除来自母亲外,其余可在嫌疑父亲带中找到,肯定了孩子与嫌疑人的父子关系。MYO DNA 探针在亲子鉴定与个人识别的法医学鉴定中有着重要的实用价值。     

根据Y-染色体特异DNA序列鉴定牙齿性别

人类牙齿的性别鉴定,是法医学个体识别中的一个重要部分。作者们应用限制性内切酶 HaeⅢ、Sau3A 水解60颗牙髓 DNA,琼脂糖凝胶电泳分离酶解片段,在紫外灯下直接观察。根据 Y-染色体特异 DNA 序列,3.4kb 长片段的有无,判断牙齿的性别。为牙齿性别的法医学鉴定提供了一种简单、准确的新方法。     

The political economy of central bank intervention

This paper analyzes an exchange rate policy game between a central bank and rational speculators under symmetric information. The central bank tries to counteract shocks to the exchange rate by means of sterilized intervention working through the expectations channel. Private speculators resist being fooled. They anticipate the interventions. An “intervention bias” results with an inefficiently high equilibrium volume of intervention which does not reduce the impact of shocks to the exchange rate. The model implies that the more independent the central bank the smaller and the more consistent the intervention efforts. An empirical illustration lends some support to the model.     

Disposable income,unemployment, inflation and state spending in a dynamic political-economic model

This paper formulates a medium-term macroeconomic model of disposable income, unemployment, inflation and state spending, proposes a theory of qualitative choice to explain electoral popularity in terms of these variables and develops three approaches to the formulation of political-economic policy. The first approach is static, sets the tax rate to reconcile the interests of various pressure groups and yields a political trade-off between the private and public sector. The second approach relies on maximizing the probability of winning the next election and gives rise to a political business cycle unless the electorate votes strategically. The implications of crowding out of private investment under alternative monetary rules, autonomous behaviour of the state bureaucracy and tax-indexation for the political business cycle are also examined. The third approach analyzes the objective of maximizing the uninterrupted length in office. It yields a short-run political cycle superimposed on a longer cycle.

Comparison of Anonymous Versus Confidential Survey Procedures: Effects on Health Indicators in Dutch Adolescents

Self-report questionnaires are frequently used in youth research, but doubt remains whether total anonymity affects the results. This study compared the responses of 704 mainly 16–17-year-old adolescents to self-report measures of various health indicators in 2 groups: anonymous and confidential collection. For most health indicators no significant differences were found. Perceived health, use of alcohol, and aggressive behavior (for boys) were reported significantly less frequently in the confidential group (small effect size). It appeared that pupils with high scores on social desirability do not respond differently at most health indicators in the 2 conditions. For most health characteristics, epidemiologically useful outcomes may be derived from confidential self-report measures, which are also valuable for detecting individual at-risk children. Similar studies in lower grades and other types of education should confirm the results.Youth Department, Municipal Health Service Rotterdam area.

从某市公安警力配置情况看基层公安机关警力不足的表现及其原因和对策

基层公安机关警力不足不仅制约了公安职能的充分发挥,影响了公安机关的整体形象,而且损害了公安民警的身心健康,队伍凝聚力与吸引力受到挑战。公安机关任务量成倍增长,警力总量增长与之不相适应,侦查办案和治安管理的难度不断加大,执法要求越来越高,公安工作科技含量还不高,部分民警素质还不适应现代警务要求,警力资源内部配置不尽科学合理等,是造成当前基层公安机关警力不足的主要原因。而要解决基层公安机关警力不足的问题,一是增加公安专项编制,使基层公安机关警力与所承担任务尽可能相匹配;二是深化管理和改革,努力发挥现有警力资源的最大效能;三是以各种辅助力量为依托,实现向民力要警力;四是坚持科技强警,提升公安工作信息、技术和装备水平。
