江泽民对社会主义核心价值体系构建的理论贡献

以江泽民同志为核心的党的第三代领导集体面对国内外非常复杂的局面,始终坚持马克思主义指导思想,以科学的理论武装人;牢固树立社会主义共同理想和共产主义最高理想,以正确的方向引导人;着重培育民族精神和时代精神,以高尚的精神塑造人;强调以优秀的作品鼓舞人,引导人们知荣明耻,树立良好社会风尚,为社会主义核心价值体系的构建作出了重要的理论贡献。     

基于价值链视角的MBA教育创新思考

中国的企业要提升竞争力．需要的是工商管理硕士这类既有知识又有实践经验的稀缺性人力资源。MBA教育作为这种资源的供应商，扮演了重要的价值创造角色，肩负着为中国发展培养高素质经营管理人才的历史重任。身份象征、知识结构改善、职业目标实现及扩展人脉等MBA的价值通过其价值活动得以实现。为了进一步提升MBA教育的竞争力，需要对MBA进行价值创新。通过减少教育产业竞争所比拼的元素，采用最适合中国文化的教育模式节省成本；再通过增加和创造产业未曾提供的元素,优化整个的MBA教育从而提升了买方价值。这两种行为的交汇点便实现了MBA价值创新。     

商店形象、顾客情绪与购物价值——理论模型及实证检验

以414名百货商店消费者为调查对象,通过结构方程模型对商店形象、顾客情绪与购物价值的关系机理进行了实证分析。结果表明,商店形象通过顾客情绪对购物价值产生积极的影响作用。其中,商店形象的六维度对愉悦情绪有积极影响,而对唤起情绪有积极影响的只有服务形象、氛围形象和促销形象,并且,顾客的唤起情绪积极影响愉悦情绪。同时,顾客的愉悦情绪对购物价值三维度均有积极影响,而唤起情绪仅对享乐性和社会性购物价值有积极影响。这些研究结论对零售企业具有管理启示作用。     

“废墟”诞生“花”的海洋——论诗歌精神的大规模还乡

诗歌精神是民族、时代和个人的宝贵财富。诗歌的外在生存环境制约着诗歌精神的发展,时代的困窘,诗歌精神一度衰微,致使集体还乡的艰难。汶川地震发生后涌现出大量的诗篇,诗歌的青春和活力再次不可遏止的迸发,那撼动人心的诗性光辉预告着诗歌精神大规模的回归与还乡。     

Failure Probability Under Parameter Uncertainty

In many problems of risk analysis, failure is equivalent to the event of a random risk factor exceeding a given threshold. Failure probabilities can be controlled if a decisionmaker is able to set the threshold at an appropriate level. This abstract situation applies, for example, to environmental risks with infrastructure controls; to supply chain risks with inventory controls; and to insurance solvency risks with capital controls. However, uncertainty around the distribution of the risk factor implies that parameter error will be present and the measures taken to control failure probabilities may not be effective. We show that parameter uncertainty increases the probability (understood as expected frequency) of failures. For a large class of loss distributions, arising from increasing transformations of location‐scale families (including the log‐normal, Weibull, and Pareto distributions), the article shows that failure probabilities can be exactly calculated, as they are independent of the true (but unknown) parameters. Hence it is possible to obtain an explicit measure of the effect of parameter uncertainty on failure probability. Failure probability can be controlled in two different ways: (1) by reducing the nominal required failure probability, depending on the size of the available data set, and (2) by modifying of the distribution itself that is used to calculate the risk control. Approach (1) corresponds to a frequentist/regulatory view of probability, while approach (2) is consistent with a Bayesian/personalistic view. We furthermore show that the two approaches are consistent in achieving the required failure probability. Finally, we briefly discuss the effects of data pooling and its systemic risk implications.     

Peer Victimization,Self‐esteem,and Ego Resilience Types in Adolescents: A Prospective Analysis of Person‐context Interactions

This study examined bidirectional, longitudinal associations between peer victimisation and self‐esteem in adolescents, and tested for moderator effects of undercontrolling, overcontrolling, and ego‐resilient personality types in these associations. Data were used from 774 adolescents ages 11–16 years who participated in a three‐wave (i.e., 2005, 2006, and 2007) longitudinal study. Structural equation modelling analyses in Mplus demonstrated that, controlling for earlier levels of self‐esteem, self‐reported peer victimization was associated with lower self‐esteem across one‐year time intervals. Vice versa, however, low self‐esteem was not predictive of subsequent self‐reported victimization. Evidence was also found for a moderator effect of personality type on the longitudinal associations between self‐esteem and victimization. Only in the subgroup of overcontrolling adolescents was lower self‐esteem related to subsequently higher levels of peer victimization; their undercontrolling and ego‐resilient peers were unaffected.     

Girlz II women: Age‐grading,language change and stylistic variation

Informed by abstract models of language change or stability over time, we present a longitudinal study of two African American females, first interviewed as teenagers, and re‐recorded twenty years later. As teenagers, they used morpho‐syntactic features of AAVE voraciously. But as working adults, these women distance themselves from their teenage activities and social networks, and display a considerably reduced vernacular usage that accords with their articulated concern to get ahead. The diachronic interpretation that best characterizes their transformation is age‐grading rather than generational change, since change at the individual level is accompanied by stability at the community level. The picture is complicated by intermediate recordings showing that one of the speakers is a stylistic chameleon, capable since her teenage years of varying copula absence rates depending on addressee, topic, and projected persona. But the age‐grading interpretation of change at the individual level remains valid based on the evidence of her reduced use of habitual be2, and third singular present tense –s absence. The case highlights the importance of paying more attention to stylistic variation and including more than two time points in sociolinguistic studies of change in real and apparent time.

儒家君子是中国古代社会的重要人才与精神形象,其核心价值观是其长期存在的根本原因。其核心价值观主要有：天地人和是君子最高理想价值观,智仁勇三德是君子内在品质价值观,尊道贵德是君子内在精神价值观,义以为上是君子精神外现价值观,德才兼备是君子人才素质价值观。儒家君子的核心价值观对当代人才观具有重要启示：一是利于把握人才的培养方向,二是利于衡量人才的基本素质,三是利于确定人才的价值取向。     

Inference in Targeted Group‐Sequential Covariate‐Adjusted Randomized Clinical Trials

This article is devoted to the construction and asymptotic study of adaptive, group‐sequential, covariate‐adjusted randomized clinical trials analysed through the prism of the semiparametric methodology of targeted maximum likelihood estimation. We show how to build, as the data accrue group‐sequentially, a sampling design that targets a user‐supplied optimal covariate‐adjusted design. We also show how to carry out sound statistical inference based on such an adaptive sampling scheme (therefore extending some results known in the independent and identically distributed setting only so far), and how group‐sequential testing applies on top of it. The procedure is robust (i.e. consistent even if the working model is mis‐specified). A simulation study confirms the theoretical results and validates the conjecture that the procedure may also be efficient.
