Nonparametric Estimation of Item and Respondent Locations from Unfolding-type Items

Unlike their monotone counterparts, nonparametric unfolding response models, which assume the item response function is unimodal, have seen little attention in the psychometric literature. This paper studies the nonparametric behavior of unfolding models by building on the work of Post (1992). The paper provides rigorous justification for a class of nonparametric estimators of respondents’ latent attitudes by proving that the estimators consistently rank order the respondents. The paper also suggests an algorithm for the rank ordering of items along the attitudes scale. Finally, the methods are evaluated using simulated data.

父母成人依恋、怜悯与亲子关系质量:主客体互倚分析

本研究考察了父母的成人依恋对亲子关系的影响以及怜悯的中介作用。采用方便取样法调查广东省某市小学2~5年级学生的父母。534对父母自我报告了各自的成人依恋、怜悯和亲子关系质量。主客体互倚模型分析发现：（1）父母各自的依恋焦虑和依恋回避显著负向预测自己与孩子的关系质量（主体效应）,但无法显著预测伴侣与孩子的关系质量（客体效应）;（2）父母各自的怜悯在上述主体效应中起到中介作用;（3）母亲的怜悯在自身依恋回避对父子关系的客体效应中起到“遮掩效应”;（4）母亲的怜悯在自身依恋焦虑对父子关系的客体效应中起到中介作用。研究结果有利于从成对关系视角理解父母成人依恋如何影响亲子关系,实际干预中可以通过提高父母的怜悯能力来改善亲子关系。     

A stronger latent‐variable methodology to actual–ideal discrepancy

We introduce a latent actual–ideal discrepancy (LAID) approach based on structural equation models (SEMs) with multiple indicators and empirically weighted variables. In Study 1, we demonstrate with simulated data, the superiority of a weighted approach to discrepancy in comparison to a classic unweighted one. In Study 2, we evaluate the effects of actual and ideal appearance on physical self‐concept and self‐esteem. Actual appearance contributes positively to physical self‐concept and self‐esteem, whereas ideal appearance contributes negatively. In support of multidimensional perspective, actual‐ and ideal‐appearance effects on self‐esteem are substantially—but not completely—mediated by physical self‐concept. Whereas this pattern of results generalises across gender and age, multiple‐group invariance tests show that the effect of actual appearance on physical self‐concept is larger for women than for men.

从家长的角度探讨有关低出生体重儿的生命伦理学问题

为了了解家长关于低出生体重儿医疗救治权的观点,为医疗决策提供伦理学依据,按1：1匹配各选择124例单胎低出生体重儿及正常儿建立队列,调查两组家长对低出生体重儿医疗救治观点的认识。结果显示,两组家长大多认同低出生体重儿应积极救治且医疗救治权应当由医生和家长共同决定。因此,应加强围产期保健教育,积极预防低体重儿出生。     

Japanese parents' estimates of their own and their children's multiple intelligences: Cultural modesty and moderate differentiation

Abstract:  A total of 198 Japanese parents completed a questionnaire concerning their own and their children's estimated overall general (g), and multiple intelligences. Japanese parents' self-estimates were somewhat lower than those found in the Western populations but males (fathers) rated their own overall "g" score and seven Gardner multiple intelligences, significantly higher than did females (mothers). There were few sex differences, however, when parents rated sons or daughters. Parents' own IQ estimate was the best predictor of the first (eldest) child's estimated IQ. A regression analysis indicated that the best predictors of self-estimated overall "g" intelligence were self-estimated verbal and numeric intelligences. Children's age and sex, and parents' age and sex, were all non-significant predictors of the overall "g" score estimates of the first two children. There were no sex differences in experience of, or attitudes towards, intelligence testing. A number of cultural differences were found compared with other studies in Western cultures.

Accessing the multitude within: A psychoanalytic perspective on the transformation of masculinity at mid‐life1

This paper reflects upon the essential components of male identity that commonly are reworked in middle age. The author argues that healthy masculine gender identity involves an ongoing, plastic process of destabilization and reconstruction at various pivotal developmental stages, particularly during middle adulthood. In essence, a man's mature transformation of his sense of masculinity results when finite concepts of gender identity are superseded by an awareness of the complexity of one's multiple, early and diverse gender identifications. A clinical case provides insight into how psychoanalytic treatment can contribute to a new experience of masculinity. The case illustrates how a maturing man, meeting an altered sense of identity in mid‐life, relies less on gender splitting and more on reuniting previously antithetical intrapsychic elements. Why this more pluralistic, polythreaded masculinity frequently must wait until mid‐life is further clarified. Specific importance is attached to the early development of male gender identity as it is founded on the boy's unique struggles in separating from his mother. The foundation for male gender identity formation is reconsidered as the author questions the ‘dis‐identification’ model while explicating how the boy's striving for narcissistic completion shapes the gendered masculine ego ideal. Classically termed ‘phallicism’ is understood both to facilitate and obstruct a man's adult development, while the concept of ‘genitality’ is augmented by the postclassical notion of ‘interiority’. At mid‐life, ‘phallic’ ego ideals (resting on omnipotence, desires for narcissistic completion and gender splitting) are transformed into more realistic, ‘genital’ ego ideals (synthesizing autonomy and connection). The achievement of a mature, less sharply gendered ‘masculine’ ego ideal (revitalizing the foreclosed dimensions of both the early maternal and paternal imagos) occurs as the balance of forces shifts in the direction of true genitality rather than defensive phallicism.     

青少年及其家长应付方式、心理健康状况的相关研究

研究者通过对800名12——16岁中学生及其家长的测试,比较了青少年及其家长应付方式、心理健康状况的异同和相关,结果表明：1、中学生的积极、成熟应付方式和心理健康状况低于成年人;2、青少年的应付方式与其家长的应付方式呈现出同质化的特点,观察、模仿家长是形成青少年应付方式的重要途径;3、“合理化”应属于不成熟的应付方式。
