Assessing the devolution revolution: How accurate are state-level estimates from the current population survey

The devolution of many social policy responsibilities from the Federal government to states has prompted increased interest in state-level measures of need. One data source that could be used to provide more state-level information on a variety of topics is the Current Population Survey (CPS). During the past ten years the CPS has been used to produce state-level estimates on a variety of measures. However, there has been little systematic evaluation of these data. This paper provides measures of accuracy for several state-level estimates derived from the CPS. These include standard errors for single-year estimates, three-year averages, and five-year averages of the March CPS measures; standard errors for three-year averages of 12-month CPS files; and comparison of CPS-based estimates to data from the Decennial Census. The paper also examines the relative accuracy of CPS estimates based on states' size. The information in this study will help analysts better understand the tradeoffs between timeliness and accuracy to be considered when using state-level estimates derived from the CPS.     

Binary Dynamic Logit for Correlated Ordinal: estimation,application and simulation

We evaluate the estimation performance of the Binary Dynamic Logit model for correlated ordinal variables (BDLCO model), and compare it to GEE and Ordinal Logistic Regression performance in terms of bias and Mean Absolute Percentage Error (MAPE) via Monte Carlo simulation. Our results indicate that when the proportional-odds assumption does not hold, the proposed BDLCO method is superior to existing models in estimating correlated ordinal data. Moreover, this method is flexible in terms of modeling dependence and allows unequal slopes for each category, and can be used to estimate an apple bloom data set where the proportional-odds assumption is violated. We also provide a function in R to implement BDLCO.     

高校人力资源管理存在的问题与对策研究

家庭托育点管理实践及启示：政策工具的视角

家庭托育点的规范化对婴幼儿健康成长至关重要。通过文献收集和访谈获得既往管理举措和当前试点政策,运用政策工具进行分析和总结,探究管理家庭托育点的背景、对象和措施。结果表明：家庭托育点因经济优势而被纳入管理,现有征求意见稿管理对象偏向小规模邻托,但试点和市场偏向较大收托规模;消防审查依托既有消防验收,师资准入要求偏低,质量监管依靠政府。管理建议：应根据收托规模区分小型和大型家庭托育点开展试点;完善三方协同的管理架构,设定专门空间环境要求,提高师资准入要求,建立综合质量监管。     

中国行政效率的公共选择理论分析

从公共选择理论看来,政府在弥补市场失灵的同时,自身也会产生失灵。但是,中国在从计划经济向市场经济转型过程中,政府行政低效问题主要原因在于自身制度不够完善,如组织的约束机制和组织监控机制的不完善等。主要表现为政府决策达不到帕累托最优、无法评价市场机制与政府干预,何者的作用更大等。因此,必须通过引入竞争机制、进行成本-受益分析和加强监督等措施加以解决。     

培养大学生科学的择业观

解决当前大学生就业问题的关键之一是培养科学的择业观.针对当前大学生择业观的现状及存在的问题应采取一系列培养对策。政府应为大学生充分就业提供有力的政策支持;高校应把就业指导贯穿于大学学习的全过程;学生应积极适应社会需要,立志报效祖国等等。     

RESEARCHING RELATIONSHIPS FROM AN ATTACHMENT PERSPECTIVE: THE USE OF BEHAVIOURAL,INTERVIEW, SELF‐REPORT AND PROJECTIVE MEASURES

Having demonstrated its credentials as one of the more elegant and robust conceptualisations of human relationships, attachment theory has considerable relevance to social work. Attachment‐based research has flourished over the past few years and it now includes an impressive array of studies across the lifespan. This article considers four different measures used in attachment‐based research, although more discussion is devoted to interview and projective measures because they specifically embrace a psychodynamic approach in their design and analytic focus. The aim of the article is to provide a brief overview of each measure and to offer some illustrative examples using practice‐related material.     

Nonparametric analysis of treatment effects with missing observations

This paper develops a test for comparing treatment effects when observations are missing at random for repeated measures data on independent subjects. It is assumed that missingness at any occasion follows a Bernoulli distribution. It is shown that the distribution of the vector of linear rank statistics depends on the unknown parameters of the probability law that governs missingness, which is absent in the existing conditional methods employing rank statistics. This dependence is through the variance–covariance matrix of the vector of linear ranks. The test statistic is a quadratic form in the linear rank statistics when the variance–covariance matrix is estimated. The limiting distribution of the test statistic is derived under the null hypothesis. Several methods of estimating the unknown components of the variance–covariance matrix are considered. The estimate that produces stable empirical Type I error rate while maintaining the highest power among the competing tests is recommended for implementation in practice. Simulation studies are also presented to show the advantage of the proposed test over other rank-based tests that do not account for the randomness in the missing data pattern. Our method is shown to have the highest power while also maintaining near-nominal Type I error rates. Our results clearly illustrate that even for an ignorable missingness mechanism, the randomness in the pattern of missingness cannot be ignored. A real data example is presented to highlight the effectiveness of the proposed method.     

Some Results Based on a Version of the Generalized Dynamic Entropies

We propose new dynamic measures of uncertainty based on the notion of generalized dynamic entropy introduced in Di Crescenzo and Longobardi (2006). These can uniquely determine distribution functions in continuous and discrete cases, and the characterizations of some well-known distributions are provided. We also define some orderings and aging notions based on the generalized dynamic measures, and prove some of their properties, obtaining as corollaries results that have recently appeared in the literature.     

我国环境刑罚轻缓化探析

毋庸置疑,在整个国际社会对环境犯罪处以轻缓刑罚的背景下,我国亦应该对环境刑罚采用轻缓化的原则。诚然,我国的环境刑罚制度与其他国家相比还有许多亟待完善的地方,但这并不妨碍我们在借鉴其他国家先进的立法经验的基础上构建适合我国具体国情的环境刑罚制度。在环境刑罚中要突出自由刑的适用,扩大并完善财产刑的适用,明确财产刑中过于模糊的规定,逐步改善环境犯罪的刑事处罚措施过于单一的缺点和功能上的不足,同时提高对辅助刑罚措施的关注。在环境犯罪方面,在适用传统刑罚措施惩治的基础上配合适用辅助刑罚措施,使我国环境刑罚轻缓化实践不至于成为一纸空谈。
