个人破产制度三论

将破产主体扩大至个人已是我国破产立法大势之所趋 ,但个人破产制度尚有一些问题需要在理论和实践中进一步认识。本文探讨了个人破产的条件、个人财产的范围以及破产者行为能力的限制等三个问题 ,以陋解就教于诸方家     

从赶超性增长到包容性发展——新时代奥运战略的战略选择

奥运战略是我国竞技体育成功实现“赶超”增长的战略支撑。当前我国正处于以新时代特色社会主义思想为指导,以全面实现治理体系和治理能力现代化为主线的社会转型期,继续实施奥运战略是持续推进竞技体育发展的关键。包容性发展理念为奥运战略的改革创新提供了新的战略思路。基于包容性发展理念下的奥运战略创新实施模式,应确立以推动竞技体育可持续,提升竞技体育整体实力为战略目标,以统筹兼顾为基本工作方针,实现竞技体育的内部均衡协调发展,以政府体育职能部门、市场企业、社会体育组织为发展主体,建立兼顾多元主体利益的利益协调机制,将以人为本、全面发展贯穿于竞技体育人才培养,实施多元目标追求的竞赛组织治理体系,以促进实现竞技体育治理体系和治理能力现代化。     

海潮灾害与范公堤的修筑——兼论范仲淹“先天下之忧而忧”思想形成的自然环境基础

范仲淹入仕之初，曾监泰州西溪盐仓。他“虽乘田委吏之卑”，仍心忧社稷民生，屡次上书言政。特别是目睹潮水泛滥，殃及百姓，范仲淹建议并参与重修捍海堰。后人为纪念他的首倡之功而称此堰为“范公堤”。这一事件，是范仲淹“先天下之忧而忧”思想形成的重要基础。后世范公堤得到多次增修，范仲淹忧国忧民精神的感召应是其中重要原因。     

PREDICTION FOR EXPONENTIAL LIFETIMES BASED ON STEP-STRESS TESTING

ABSTRACT

This paper presents methods for constructing prediction limits for a step-stress model in accelerated life testing. An exponential life distribution with a mean that is a log-linear function of stress, and a cumulative exposure model are assumed. Two prediction problems are discussed. One concerns the prediction of the life at a design stress, and the other concerns the prediction of a future life during the step-stress testing. Both predictions require the knowledge of some model parameters. When estimates for the model parameters are available, a calibration method based on simulations is proposed for correcting the prediction intervals (regions) obtained by treating the parameter estimates as the true parameter values. Finally, a numerical example is given to illustrate the prediction procedure.     

Efficient score tests for heteroskedasticity in micro-economics

Kruskal's theorem is used to provide simple and elegant alternative derivations of the efficiency of some two step estimators (2SE) for models containing anticipated and unanticipated variables. Several new results are established: 2SE is not efficient for a structural equation with current and lagged values of both anticipated and unanticipated variables; 2SE is always efficient for the parameter associated with the current unanticipated variable, and for the parameter associated with the lagged unanticipated variable if there is no lagged dependent variable in the expectations equation; the inclusion of additional regressors in the structural equation and contemporaneous correlation of the structural and expectations errors can both be analysed in a straightforward manner; the single-equation generalized least squares estimator can be as efficient as the systems maximum likelihood estimator.     

海峡西岸经济区在构建海峡经济区中应先行一步

海峡经济区的形成是经济发展的必然规律。海峡西岸经济区与海峡东岸经济区的连接(主要是福建与台湾的连接),构成海峡经济区的核心区。海峡东岸经济区需要向海峡西岸经济区拓展空间,海峡西岸经济区具备与海峡东岸经济区连接的充分条件,海峡西岸经济区在构建海峡经济区中应先行一步。     

Trainees' Views of the Step Up to Social Work Programme

There are long-standing concerns about the quantity and quality of social workers in England. Several initiatives have sought to change application and training processes, among which are employment-based routes whereby students are placed with social work employers and receive substantial funding compared to other students, and employers are more closely engaged with higher education elements of their training. This article presents and analyses the views of the first cohort of students, termed trainees, in one such initiative, the Step Up to Social Work programme that commenced in 2010. Data were collected by online survey, administered at four time points with response rates ranging from 78% at Time 1 to 71% at Time 2, 64% at Time 3 and 71% at Time 4. Findings revealed that the respondents were largely satisfied with their training and the Step Up initiative, although reservations were expressed by some about academic teaching, programme organisation and apparent lack of account of trainees' previous experiences. Findings also reveal the type and extent of the trainees' academic achievements and professional experiences. The findings from this first cohort of trainees may usefully inform other employment-based routes and social work education more generally.

Covariance changes detection in multivariate time series

This paper studies the detection of step changes in the variances and in the correlation structure of the components of a vector of time series. Two procedures based on the likelihood ratio test (LRT) statistic and on a cumulative sums (cusum) statistic are considered and compared in a simulation study. We conclude that for a single covariance change the cusum procedure is more powerful in small and medium samples, whereas the likelihood ratio test is more powerful in large samples. However, for several covariance changes the cusum procedure works clearly better. The procedures are illustrated in two real data examples.
