Dashed Hopes,Dashed Selves? A Sociometer Perspective on Self‐esteem Change Across the Transition to Secondary School

The transition from primary to secondary school challenges children's psychological well‐being. A cross‐transitional longitudinal study (N = 306; mean age = 12.2 years) examined why some children's self‐esteem decreases across the transition whereas other children's self‐esteem does not. Children's expected social acceptance in secondary school was measured before the transition; their actually perceived social acceptance was measured after the transition. Self‐esteem and Big Five personality traits were measured both pre‐ and posttransition. Self‐esteem changed as a function of the discrepancy between children's expected and actually perceived social acceptance. Furthermore, neuroticism magnified self‐esteem decreases when children's ‘hopes were dashed'—when they experienced disappointing levels of social acceptance. These findings provide longitudinal support for sociometer theory across the critical transition to secondary school.     

《贞观政要》官德保障机制论要

《贞观政要》继承和发展了儒学政治哲学的人性理论。其官德保障机制体现在内修与外治两个方面,一则从非制度的内在层面强调官吏通过思、慎和学的途径修身养德,二则从制度的外在层面加强旨在预防、考课与奖惩官员的吏治建设。体现自律与他律、儒学政治哲学与法家政治理念的统一,完善了中国传统政治外儒内法的基本模式。     

Pitman closeness,monotonicity and consistency of best linear unbiased and invariant estimators for exponential distribution under Type II censoring

Comparisons of best linear unbiased estimators with some other prominent estimators have been carried out over the last 50 years since the ground breaking work of Lloyd [E.H. Lloyd, Least squares estimation of location and scale parameters using order statistics, Biometrika 39 (1952), pp. 88–95]. These comparisons have been made under many different criteria across different parametric families of distributions. A noteworthy one is by Nagaraja [H.N. Nagaraja, Comparison of estimators and predictors from two-parameter exponential distribution, Sankhyā Ser. B 48 (1986), pp. 10–18], who made a comparison of best linear unbiased (BLUE) and best linear invariant (BLIE) estimators in the case of exponential distribution. In this paper, continuing along the same lines by assuming a Type II right censored sample from a scaled-exponential distribution, we first compare BLUE and BLIE of the exponential mean parameter in terms of Pitman closeness (nearness) criterion. We show that the BLUE is always Pitman closer than the BLIE. Next, we introduce the notions of Pitman monotonicity and Pitman consistency, and then establish that both BLUE and BLIE possess these two properties.     

自我意识是一个伦理原则——马克思博士论文伦理思想探析

在博士论文中,马克思确立了自我意识哲学的主体地位。表面看是在阐释伊壁鸠鲁哲学,实际上＂已经显示出了马克思的创造的智慧＂。在他的理论视域内,自我意识是一个伦理原则,有着丰富的伦理内涵,展现了其在走向社会批判以前＂伦理批判＂的思想特质。     

Large sample bias of maximum likeihood estimates from a series of sparse ixj tables

For a large series of IxJ tables, each containing two observations, the bias of the maximum likelihood estimates of log linear partial association parameters is shown to be equal to the parameters, regardless of the size of I and J. The partial association considered is that between row and column variables; the three way interactions are assumed to be O. This is a generalization of Andersen's results (1973a, 1973b) for a series of 2x2 tables.     

Sequential estimation problems for negative exponential populations

The literature on sequential estimation problems for negative exponential populations has been reviewed here, We attempt to bring in all the published and unpublished materials known to us in a fairly coherent fashion. Both the concepts and theoretical findings are discussed.     

Vocational education,self‐employment and burnout among Australian workers

We examine the relationship between vocational education and occupational burnout among workers in different forms of employment. Although the self‐employed enjoy higher levels of job autonomy and work‐related satisfaction, we do not know whether they experience lower rates of occupational burnout, and whether vocational education plays a role in this relationship. This latter consideration is important, given that vocational qualifications often lead to self‐employment and prior research demonstrated that formal training may reduce burnout. However, formal education was previously measured in years of schooling, without considering the distinction between academically‐oriented and vocational courses. Therefore, using data from a 2001 national survey of working Australians, we first establish that the self‐employed are significantly less likely to experience burnout. We then demonstrate that some resilience to burnout can be attributed to the attainment of skilled vocational training, net of employment characteristics which are also very important.     

加拿大原住民自治政府:联邦主义下制度构建与政治文化相背离的困境

本文指出 ,加拿大原住民自治政府虽然具有道德正义性而且其合法性与加拿大联邦主义的原则不冲突 ,但其作为一个在联邦制度内的制度构建与加拿大的主导政治文化和政治权力结构却有一种背离矛盾关系。这种主导共同体与亚集体认同矛盾的现象在多民族国家的政治制度构建中是带有普遍性的问题 ,如何在宪政建设中解决这个问题对加拿大联邦制的前景至关重要 ,而且对中国这样的多民族国家将来的宪政建设也有很大的启示作用     

Poverty and Self‐Control

We argue that poverty can perpetuate itself by undermining the capacity for self‐control. In line with a distinguished psychological literature, we consider modes of self‐control that involve the self‐imposed use of contingent punishments and rewards. We study settings in which consumers with quasi‐hyperbolic preferences confront an otherwise standard intertemporal allocation problem with credit constraints. Our main result demonstrates that low initial assets can limit self‐control, trapping people in poverty, while individuals with high initial assets can accumulate indefinitely. Thus, even temporary policies that initiate accumulation among the poor may be effective. We examine implications concerning the effect of access to credit on saving, the demand for commitment devices, the design of financial accounts to promote accumulation, and the variation of the marginal propensity to consume across income from different sources. We also explore the nature of optimal self‐control, demonstrating that it has a simple and behaviorally plausible structure that is immune to self‐renegotiation.
