具有时滞的Hopfield神经网络的周期解

假设具有时滞的Hopfield神经网络的每个输出响应函数是满足Lipschitz条件的有界函数,当该网络的输入信号始终以正常数ω为周期,并且在网络参数满足一定的条件时,通过构造适当的Lyapunov泛函的方法,得到了该类网络必存在唯一的ω-周期解,并且其余各解都按指数收敛于该周期解的一些判据,通过实例对所得到的判据进行了直观性解释。     

我国煤矿人员对煤矿城市投入产出效率的影响——基于DEA的实证研究

随着煤炭从业人员比重的下降,地县两类煤矿城市的投入产出总体效率明显不同,县级煤矿城市的规模效率明显不如地级煤矿城市;而且两类城市的投入产出的相对冗余率在组内也相差很大。因此,对不同类型和组别的煤矿城市必须进行分类指导,以促进我国煤矿城市的规范发展。

基于劳动者平均工资的人力资本计量模型研究

人力资本计量是研究教育对经济贡献率过程中的重要环节, 因为教育是通过转换为人力资本, 才对经济产生推动作用的。在计量人力资本时, 运用较多的是基于成本的教育年限法和基于收入的劳动者平均工资法。本文给出了基于成本的教育年限法的缺陷, 介绍了计量人力资本的另一种方法, 即用一个地区的人均总产出除以该地区纯体力劳动者的平均工资, 并通过搜集实际数据计算比较我国 31 个省(市、自治区) 的人力资本水平。     

Promoting choice and control in residential services for people with learning disabilities

This paper discusses the gap between policy goals and practice in residential services for people with learning disabilities. Drawing on a nine month ethnographic study of three residential services, it outlines a range of obstacles to the promotion of choice and control that were routinely observed in the culture and working practices of the services. Issues discussed include conflicting service values and agendas, inspection regimes, an attention to the bigger decisions in a person's life when empowerment could more quickly and effectively be promoted at the level of everyday practice, problems of communication and interpretation and the pervasiveness of teaching. We offer a range of suggestions as to how these obstacles might be tackled.

我国农村医疗保障立法刍议

制定我国农村医疗保障法既有现实必要性,又有重要意义。农村医疗保障立法有助于提高农民对农村医疗保障的信任度,有助于农村医疗保障资金的筹集,有助于加强对农村医疗保障基金的监管,有助于理顺农村医疗保障管理体制。然而,目前我国农村医疗保障法律法规明显滞后于医疗保障事业发展需要,主要表现为:立法体系不完备,立法层次偏低,法规实施机制不健全。对此,我们要深刻把握立法规律,提高立法层次,完善法规体系,改进立法技术,积极推进我国农村医疗保障立法进程。

Unintended Consequences: The Impact of Welfare Reform in the United States on NGOs

The Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) of 1996 dramatically transformed the structure and goals of the public welfare system in the United States. The vast body of research and evaluation generated by the 1996 welfare reforms largely overlooked nongovernmental organizations (NGOs) despite their substantial historical and contemporary involvement in the delivery of social services to low-income populations. Therefore, this paper presents a unique assessment of PRWORA's implications based on the perspective of 90 social service NGOs operating in the Detroit metropolitan area. Examination of their services, staffing, budgets, and clients reveals many changes experienced by NGOs between 1996 and 2000 related to the welfare reforms. Overall, the findings suggest an increased role for social service NGOs in the public welfare system as well as concerns regarding their capacity to adequately fulfill this growing responsibility in the future.
