书法练习对儿童情绪及其调节策略发展的促进作用

本研究采用纵向设计,对170名儿童（实验组：101人;对照组：69人）进行为期两学年的追踪,旨在探讨书法练习对儿童情绪状态及认知性情绪调节策略发展的影响。研究发现,1）以前测成绩为协变量,后测时实验组的积极情绪显著高于对照组;2）实验组在“积极重新关注”、“计划”两维度上的情绪调节策略得分增量（后测-前测）显著高于对照组。结果表明,书法练习对儿童情绪及其调节策略发展具有促进作用。     

Aggression in Toddlers: Associations With Parenting and Marital Relations

This study examined the relation among parenting factors, marital relations, and toddler aggression. A structured questionnaire was administered to both parents of 254 2-year-olds. The authors used correlation and hierarchical multiple regression analyses to assess the extent to which certain personality traits, drug use, parenting style, and marital conflicts were related to the toddlers' aggressive behavior. Results showed that the maternal child-rearing and parental aggression domains had a direct effect on toddler aggression. The domain of maternal child rearing also served as a mediator for the domains of marital relations, paternal child rearing, parental aggression, and parental drug use. The findings indicated that maternal child-rearing practices, personality attributes, and drug use were more important than paternal attributes in relation to toddler aggression. Implications for prevention among families at risk are discussed.     

Discriminant Analysis Using Mixed Continuous,Dichotomous, and Ordered Categorical Variables

This article proposes an intuitive approach for predictive discriminant analysis with mixed continuous, dichotomous, and ordered categorical variables that are defined via an underlying multivariate normal distribution with a threshold specification. The classification rule is based on the comparison of the observed data logarithm probability density functions. To reduce the computational burden, the analysis is conducted in the context of a confirmatory factor analysis model with independent error measurements. Identification of the dichotomous and ordered categorical variables is discussed. Results are obtained by implementations of a Monte Carlo expectation maximization (MCEM)algorithm and a path sampling procedure. Probabilities of misclassification are estimated via the idea of the “jackknife” method. A real example is given to illustrate the proposed method.     

A regular arrangement of SmH2 fibres in an alpha-Fe matrix,found after the hydrogenation-disproportionation processing of Sm2Fe17

In the course of a study on microstructural changes in Sm2Fe17 during a hydrogenation-disproportionation-desorption-recombination process, a peculiar microstructure has been observed just after the hydrogenation-disproportionation processing. SmH2 crystals, formed as a result of decomposition of the Sm2Fe17 compound, are present with a fibrous shape, about 7 nm in diameter and 1 mum in length. These SmH2 fibres, all with the same orientation, are arranged at nearly regular intervals of about 11nm and with a definite orientation relationship to the alpha-Fe matrix, <110> Fe// <110> SmH2.     

Valence band structure of the NiAl–Mo alloy from the photoelectron spectrum

The valence band structures of the NiAl–Mo alloy was investigated by photoelectron spectroscopy. The valence band spectra of the NiAl–Mo alloy was shifted away from the Fermi level so that the Ni-d-band centroid moved to a higher energy by 0.22 eV as Mo was added. A possible explanation lied in the overlap of Ni-d bands in the energy with Mo-d and Al-p bands. The participation of Mo-d bands was correlated with the site preference of Mo in NiAl alloys.     

Formation of metastable phase and its influence on the solidification microstructure of highly undercooled eutectic Fe40Ni40B20 alloy

Solidification of a highly undercooled eutectic Fe₄₀Ni₄₀B₂₀ alloy melt has been studied by high-speed video in combination with an analysis of the temperature history. The metastable phase with a colony shape structure solidified primarily from the melt. DSC analysis confirmed the formation of the metastable phase. The metastable phase was re-melted, transformed or decomposed into stable phases during further solidification or cooling processes, and gave birth to the final as-solidified structures. On this basis, the effects of the metastable phase formation and transformation on evolution of the as-solidified structure is described.     

通货膨胀、通货紧缩和产品类型对货币幻觉的影响

货币幻觉是指经济交易活动中,人们因倾向于以货币的名义价值而非实际价值思考从而对其消费和投资行为造成影响的一种认知偏差。本研究探讨了在通货膨胀和通货紧缩下以及产品类型对货币幻觉程度的影响。研究发现,在通货膨胀或通货紧缩下,大部分被试判断经济状况时不受货币名义价值的影响,而判断快乐程度和离职意向时受到货币名义价值的影响;在相同的涨价幅度下被试对日常消费品和昂贵消费品涨价幅度的判断差异显著,昂贵消费品引起人们更高程度的货币幻觉。     

Dispositional and Situational Autonomy as Moderators of Mood and Creativity

Although previous research suggests that mood can influence creativity, the controversy about the effects of positive and negative moods has raged for years. This study investigated how the relationship between induced mood and creativity is moderated by dispositional and situational autonomy. It contrasted the different moderating effects of the 2 kinds of autonomy. In Experiment 1, 93 participants completed a questionnaire about dispositional autonomy and performed a creative task after watching 1 of 3 film clips, which were to induce positive, negative, or neutral moods. The results of experiment 1 indicated that positive moods prompted creativity and negative moods inhibited creativity when individuals were low in dispositional autonomy (low in autonomous orientation or high in impersonal orientation). In Experiment 2, 73 participants engaged in a game to manipulate levels of situational autonomy and induce positive or negative moods. The results of experiment 2 showed that positive moods fostered greater creativity than did negative moods when individuals were in full-autonomy condition. The different moderating effects of dispositional and situational autonomy are discussed.     

THE CONTRIBUTION OF WORLD JEWISH ORGANIZATIONS TO THE ESTABLISHMENT OF RIGHTS FOR JEWS IN MOROCCO (1956–1961)

The history of the Jewish community during the early years of Moroccan independence is a story of continuous and constant worries regarding an unclear future—as well as fears of possible impending disaster. During this period, the Jewish community was forced to deal with several critical questions, the answers to which would ultimately determine the future of Moroccan Jewry, as well as the future of individual Jews in the community. While the struggle for independence had been waged without much involvement on the part of the Jewish community, the removal of the yoke of colonialism presented each Moroccan Jew with various options, and the choice to be made between them was a fateful one—whether to seek personal and communal success within a democratic progressive country or to escape from the country out of fear of a possible disaster.
