信息性从众行为和规范性从众行为比较研究

目的:从众可分成两种,即信息性从众行为和规范性从众,探讨它们两者之间的区别。方法:通过瑞文智力测验为材料创造了这两种从众情境,观察大学生被试在两种实验条件下的行为差异。结果:信息性从众和社会规范性从众两者之间存在显著差异(Z=-3.183,P=0.001)。结论:大学生被试的信息性从众行为多于社会规范性从众行为,两者存在统计学上的显著性差异。     

Dynamic balance between grain refinement and grain growth during high-pressure torsion of Cu powders

High-pressure torsion (HPT) was applied to unmilled coarse-grained (CG) Cu powders with low initial dislocation density and cryomilled nanocrystalline (nc) Cu powders with high initial dislocation density, with identical processing parameters. HPT of unmilled CG Cu powders resulted in exceptional grain refinement and increase in dislocation density, whereas significant grain growth and decrease in dislocation density occurred during HPT of cryomilled nc Cu powders. Equilibrium structures were achieved under both conditions, with very similar stable grain sizes and dislocation densities, suggesting dynamic balances between deformation-induced grain refinement and grain growth, and between deformation-induced dislocation accumulation and dislocation annihilation. The equilibrium structures are governed by these two dynamic balances.     

Stress-enhanced grain growth in a nanostructured aluminium alloy during spark plasma sintering

In this study, we report on the influence of high pressure on the microstructure evolution of cryomilled nanostructured Al alloy powders during spark plasma sintering (SPS). Our experimental results suggest that the particular mechanism that governs grain growth during SPS depends on the magnitude of the applied pressure. In the case of material consolidated at a high pressure (e.g. 500 MPa), grain coarsening occurs via a combination of thermally activated grain boundary (GB) migration, stress-coupled GB migration and grain rotation-induced grain coalescence. In contrast, in the case of the material consolidated at a low pressure (50 MPa), grain growth occurs primarily via thermally activated GB migration.     

集体主义内隐观的访谈和调查研究

在扩充样本的基础上进一步探讨集体主义概念内涵,挖掘“集体”的具体指向,明确“集体”构成.研究一通过40个被试的内隐观访谈和质性分析,得到集体主义概念五个方面内容（集体认同、集体优先、联结信念、责任与义务、发生的条件）,指出“集体”的具体指向为泛集体和关系集体,集体主义程度与冲突情境有关.研究二通过102份问卷调查和聚类分析,得到三类集体,即关系比较亲密集体（由母亲、亲兄弟/姐妹、配偶、好友构成）、关系一般集体（由认识的人、亲戚、同事、邻居构成）和关系疏远集体（由本地陌生人、国外陌生人构成）,并进一步明确了“集体”的具体构成.结论认为：集体主义概念内涵包括集体认同、集体优先、联结信念、责任与义务、发生的条件五个部分;集体主义中的“集体”由泛集体和关系集体构成,其中关系集体又分为关系比较亲密集体和关系一般集体.     

Semantic games with chance moves revisited: from IF logic to partial logic

We associate the semantic game with chance moves conceived by Blinov with Blamey’s partial logic. We give some equivalent alternatives to the semantic game, some of which are with a third player, borrowing the idea of introducing the pseudo-player called Nature in game theory. We observe that IF propositional logic proposed by Sandu and Pietarinen can be equivalently translated to partial logic, which implies that imperfect information may not be necessary for IF propositional logic. We also indicate that some independent quantifiers can be regarded as dependent quantifiers of indeterminate sequence, using the interjunction connective in partial logic. We conclude our paper by indicating some further research in a more general setting.

Race/ethnicity and sex in U.S. occupations, 1970–2010: Implications for research,practice, and policy

We used census data on the civilian non-institutional adult population to analyze trends in labor force participation by race/ethnicity and sex in U.S. occupations from 1970 to 2010 in decennial periods. We examined these data for the main effects and interactions of race/ethnicity and sex across the total labor market and within 35 detailed occupations. Results from a log-linear analysis revealed that, as a whole (across race/ethnicity), more women participated in the labor force from 1970 to 2010. The proportions of working racial/ethnic minorities to both the population and the people in the labor force increased across all decades except for Black men. Although White (Caucasian) men continuously comprised the largest racial/ethnic–sex group working across five decades in absolute numbers, their percentage of the total working population declined from 1970 (54%) to 2010 (37%). In our analyses of 35 occupations, significant sex differences within racial/ethnic groups emerged. Overall, with some exceptions, Asian men and women and White women were more likely to be absorbed into occupations typically associated with professional status whereas Black, Hispanic, and American Indian men and women were more likely to be absorbed into occupations typically associated with low skill, low wages, and low status. Implications for the role of psychologists in future research, practice, and policy are discussed.     

Modelling partially cross‐classified multilevel data

This article proposes an approach to modelling partially cross‐classified multilevel data where some of the level‐1 observations are nested in one random factor and some are cross‐classified by two random factors. Comparisons between a proposed approach to two other commonly used approaches which treat the partially cross‐classified data as either fully nested or fully cross‐classified are completed with a simulation study. Results show that the proposed approach demonstrates desirable performance in terms of parameter estimates and statistical inferences. Both the fully nested model and the fully cross‐classified model suffer from biased estimates of some variance components and statistical inferences of some fixed effects. Results also indicate that the proposed model is robust against cluster size imbalance.
