实践社区成员的成就动机对知识传播的影响

为了研究成就动机对实践社区及其成员的知识传播过程的影响,采用自编实践社区成员成就动机问卷以及知识传播过程与效果问卷对重庆、银川、南京、上海等地企业的430名实践社区成员进行测量,研究了成就动机对知识传播的影响.结果表明:问卷具有良好的信度和效度;不同性别被试的社会取向成就动机存在显著差异;工作年限为11-15年的被试社会取向成就动机识显著高于其他组别;自我取向成就动机对知识传播的路径系数除"自我取向-区内吸收"外均达到显著性水平,即对"知识传播投入程度"、"社区外知识获取能力"及"知识传播效果"的预测作用都是正向的;社会取向成就动机仅对知识传播效果产生显著影响.     

Postpartum depression and attachment: Is anybody here?

Abstract

The paper presents a developmental and dynamic multitheoretical overview of many dimensions of attachment-related processes activated under the conditions of maternal depression. The clinical vignette (from the analytic practice of Eva D. Papiasvili) of reconstructive anaytic work with an adult patient illustrates the profound impact of maternal depression on precocious early differentiation between the attachment styles, of the depressed parent and the substitute caregiver, at the root of early “counterdependent” self-sufficiency. Through reconstructive interpretive work, first with enactments and then dreams, pertaining to not-remembered, represented, or symbolized events of earliest infancy, the patient is able to make a series of developmentally transformative symbolic leaps, restoring the capacity for intimacy, hope, trust, and pleasure. This breaks the intergenerational mother–daughter transmission of postpartum depression and related problematic attachment.     

Cross-generational transmission of aggressive parent behavior: a prospective,mediational examination

The intergenerational transmission of aggressive parenting behavior was examined within the context of a prospective longitudinal study of adolescent and young adult adjustment. Thirty-nine young adults (G2; 33 females, 6 males) who had participated in early phases of this study with their parents (G1) continued their involvement with their young children (G3; 17 females, 22 males, mean age = 2.6) several years later. Data included direct observation of parent–adolescent (G1–G2) and parent–child (G2–G3) interactions as well as self-reports. Analyses demonstrated directly observed cross-generational continuity in aggressive parenting from G1 to G2 some 6–7 years later. However, the results also showed that adolescent aggressive behavior served as the mediational link reducing the direct path from G1 to G2 aggressive parenting to nonsignificant levels. The results are consistent with a social interactional model of intergenerational continuity of parenting behavior.     

Correctly responding to reasons while being means-end incoherent

This paper argues that Reason Responsiveness (RR) accounts of rationality, proposed for example by Benjamin Kiesewetter and Error Lord, fail to explain structural irrationality (i.e., the irrationality involved in holding incoherent attitudes). Proponents of RR hold that rationality consists in correctly responding to available reasons. Structural irrationality, they argue, is just a “by-product” of incorrect reason-responding. Applying this idea to cases of means–end incoherence, this paper shows that RR accounts must rely on a certain transmission principle. Roughly, this amounts to the principle that necessarily, if (1) A has decisive available reason to intend to E and (2) A has decisive available reason to believe that intending to M is necessary for E-ing, it follows that (3) A has decisive available reason to intend to M. By considering an example, this paper argues that even the most plausible version of this transmission principle does not hold true. It follows that one can correctly respond to one's available reasons while being means–end incoherent.     

Maternal anxiety and toddler depressive/anxiety behaviors: The direct and moderating role of children's focused attention

Attention mechanisms have a pertinent role in shaping developmental pathways to anxiety and depressive disorders. The current study examined the direct and interactive associations between maternal anxiety symptoms, children's focused attention, and children’s anxiety and depression behaviors in early toddlerhood. Participants were 150 mother-child dyads (50 % female) that were assessed at two time points. At 12 months of child age, mothers reported about their anxiety symptoms and children's focused attention. Children's focused attention was also observed and rated from an individual play task. At 18 months of age, mothers reported about children's anxiety and depression behaviors. Focused attention predicted child anxiety and depressive behaviors, with different patterns of associations between observed and reported measures of attention. There was also a significant interaction between maternal anxiety symptoms and observed children's focused attention. A positive association between maternal anxiety symptoms and child anxiety and depression symptoms was evident only for children with above-average levels of observed focused attention during play. Results suggest that different aspects of focused attention play a role in maternal reported anxiety and depression behaviors in early development and may modulate the intergenerational transmission of anxiety.     

Generation to Generation: Passing on Religious and Spiritual Beliefs and Practices

Many families face difficulties in maintaining healthy relationships. Past research has identified that religious and/or spiritual beliefs and practices can enhance family well-being. Research has also shown that religious and/or beliefs and practices can shape the aging process. Yet there exists little information on the methods through which religious and/or spiritual beliefs are passed on to future generations. This study utilized Eriksonian conceptual ideas, and grounded theory methods to conduct interviews with 13 older adults on the process through which religious and/or spiritual beliefs are passed on to children and grandchildren. Ideas are discussed for practitioners based on study findings.     

Reinforcement or compensation? The effects of parents' work and financial conditions on adolescents' work values during the Great Recession

The Great Recession brought many changes to the work and financial lives of American families. Little is known, however, about how changes in parental work conditions in recessionary times influence children's vocational development. Drawing on data from the Youth Development Study, we examine whether parents' recessionary experiences shape adolescents' work values. The findings indicate that adolescents' work values are shaped through a cross-generational reinforcement model; both extrinsic and intrinsic values are stronger when parental work conditions are more rewarding. In an exception to this pattern, unemployment among parents with low levels of education (high school degrees or less) is positively associated with children's extrinsic and intrinsic orientations, more consistent with a compensation model.     

Grain orientation effects on delamination during fatigue of a sensitized Al–Mg alloy

Fatigue crack growth experiments were conducted in humid air (RH~45%) at 25 °C on 29-mm-thick plate samples of an aluminium–magnesium (Al–Mg) 5083-H131 alloy in the long transverse (LT) direction. Samples were tested in both the as-received condition and after sensitization at 175 °C for 100 h. Delamination along some grain boundaries was observed in the short transverse plane after fatigue testing of the sensitized material, depending upon the level of ΔK and K_max. Orientation microscopy using electron backscattering diffraction and chemical analyses using transmission electron microscopy and energy dispersive spectroscopy of grain boundaries revealed that Mg segregation and the orientation of grains had key roles in the observed grain boundary delamination of the sensitized material.
