Stress-strength reliability of exponentiated Fréchet distributions based on Type-II censored data

In this paper, we consider inference of the stress-strength parameter, R, based on two independent Type-II censored samples from exponentiated Fréchet populations with different index parameters. The maximum likelihood and uniformly minimum variance unbiased estimators, exact and asymptotic confidence intervals and hypotheses testing for R are obtained. We conduct a Monte Carlo simulation study to evaluate the performance of these estimators and confidence intervals. Finally, two real data sets are analysed for illustrative purposes.     

A new aging concept derived from the increasing convex ordering

In this paper, a comparison between the life distribution of a new unit with that of a used unit in the increasing convex order is made leading to a new class of life distributions which we call “new better than used in convex ordering of second order”. This class includes as subclasses the NBU and the NBUC and is a subclass of the NBUCA class. Preservation properties under convolution, random maxima, mixing and formation of coherent structures are established. Stochastic comparisons of the excess lifetime when the inter-arrival times belong to the NBUC(2) class are developed. Some applications of Poisson shock models and a test of exponentiality against NBUC(2) alternative are presented.     

Psychometric properties of the “parent-child relationship inventory” (PCRI) in a portuguese forensic sample

In Portugal, there is a gap regarding psychological tests validated for forensic contexts, particularly those related to child custody issues. The Parent–Child Relationship Inventory (PCRI) is one of the most used instruments in child custody contexts. This study aimed to analyze the psychometric properties of PCRI in a Portuguese forensic sample. PCRI factorial structure and psychometric properties were analyzed in a sample of 144 parents involved in child custody assessments. The questionnaire showed good internal consistency, except for the parental support, autonomy, and role orientation scales. It also showed good discriminant capacity. The confirmatory factor analysis did not replicate the 7-factor model proposed by Gerard. The results were discussed based on the use of PCRI in the context of child custody assessment.     

心理契约在高校学风建设中的功能与应用

为避免高校学风建设过于强调刚性的制度建设,注重建立科学化的管理体系而忽略主观能动性的发挥,通过对心理契约的导向、凝聚、激励、整合等功能表现的挖掘,提出高校学风建设过程中教育者与受教育者之间心理契约的建立(E阶段)、调整(A阶段)和实现(R阶段),即"E-A-R模型",调动实践主体的主观能动性。     

Psychological Well‐Being and Career Indecision in Emerging Adulthood: The Moderating Role of Hardiness

This study investigated the moderating role of hardiness in the relationship between psychological well‐being (PWB) and career indecision in 131 never‐employed Italian emerging adults. Cluster analytic methods produced high and low hardiness profiles. A structural equation modeling analysis underscored the importance of hardiness for moderating the negative association between PWB and career indecision. Specifically, findings revealed that being hardy is a crucial relevant personal resource in the presence of lower levels of PWB. The authors discuss the importance of analyzing simultaneously the role of PWB and hardiness in promoting engagement in the career decision‐making process and provide implications for setting up appropriate career counseling interventions with emerging adults. Suggestions for future research are presented, such as the use of longitudinal designs and qualitative methods.

领导成员交换关系对企业员工管家行为倾向的影响研究

通过问卷调查,采集针对企业普通员工的问卷数据,探讨了领导成员交换关系与员工管家行为之间的关联关系,构建并检验了 “领导成员交换关系—心理所有权—员工管家行为倾向”作用机制模型。研究结果表明：领导成员交换关系对员工管家行为倾向有显著的正向影响,心理所有权在领导成员交换关系与员工管家行为倾向之间起部分中介作用。     

L2句子加工心理机制的ERPs研究及问题思考

国内外对L2句子加工的研究存在着较大区别。国外偏重于探讨句子加工的心理机制本身,而国内不仅探讨句子加工的心理机制本身,而且还注重探讨句子加工的心理机制所说明的问题,分析L2句子加工是否接近或相似于L1句子加工。目前,该领域的研究主要存在三种主要流派:模块说、交互说和平行说。多数学者认为L2句子加工是句法和语义加工交织的过程,即多数人接受了交互说。少数学者认为语义加工优先于句法加工。至于平行说,最近L2句子加工研究鲜有成果支持此理论。
