Adaptive self-regulation: meeting others' expectations of leadership and performance

The authors used longitudinal multisource field data to examine core aspects of the adaptive self-regulation model (A. S. Tsui & S. J. Ashford, 1994) in terms of linkages between self-monitoring, discrepancy in manager match-to-position, 5 measures of leadership, and manager performance. At Time 1, 64 superiors of focal managers rated the managers' matches to their positions within the organization; at Time 3, they rated the managers' performance. At Time 2, the 64 focal managers completed a measure of self-monitoring, and 192 subordinates rated the focal managers' leadership behaviors. Results of partial least squares analysis revealed that discrepancy in manager match-to-position was associated with reductions in laissez faire and passive management-by-exception behaviors and increases in transformational leadership behavior. Self-monitoring was positively associated with all 5 leadership behaviors. Performance was related positively to transformational leadership behavior and negatively to passive management-by-exception and contingent-reward behaviors     

Who's in Charge?: Coparenting in South and Southeast Asian Families

In light of the evolving roles of parents and the involvement of extended family within Asian cultures, the traditionally Western dyadic coparenting construct must be reconceptualized to include not only the coparenting relationship, but also other caregivers within the coparenting network. Theoretical and empirical evidence on coparental systems are discussed and two studies from South and Southeast Asian cultures are presented to highlight subcultural variations in cocaregiving networks. Results indicated that mothers were the primary caregivers across both cultural contexts. Extended family members assumed important coparental responsibilities in both cultural contexts. These findings highlight the need to reconceptualize and expand the dyadic coparental unit to include extended family members. We also discuss the relevance of the broader coparental network in examining the Asian childs education as well as cognitive and socioemotional development.     

Development and validation of an altruism scale for adults

A new self-report scale, the Altruism Scale for Adults, of 28 items was developed. 14 items were from the Altruism subscale of Wrightsman's Philosophies of Human Nature Scale, and the other 14 items were newly constructed. The scale, anchored by 1: true or 2: false, was administered to 592 Korean men and women in eight subgroups. Cronbach alpha internal consistency was .89, and test-retest reliabilities (n = 52) over 1 and 5 wk. were .90 and .80, respectively. Campbell and Fiske's 1959 multitrait-multimethod analysis showed satisfactory convergent and discriminant validities. Overall results were promising for use of the scale in research and for practical purposes.     

Help yourself by helping others: The joint impact of group member organizational citizenship behaviors and group cohesiveness on group member objective task performance change

This paper examines how a group member's individual‐targeted citizenship behavior (OCBI) and organization‐targeted citizenship behavior (OCBO) interact with a salient group‐level contextual variable, group cohesiveness, to foster positive change for that group member, starting with job self‐efficacy change, and followed by objective task performance change. Over a span of 6 months, we engaged in multilevel, multisource, multistage data collection and surveyed 587 members in 83 work groups. Our results indicate that a group member's OCBI, in comparison with OCBO, is more positively related to his or her job self‐efficacy change. Group cohesiveness was found to attenuate the relationship between a group member's OCBI and job self‐efficacy change, and conversely, to accentuate the relationship between a group member's OCBO and job self‐efficacy change. Furthermore, a group member's job self‐efficacy change mediated the interactive effects of the group member's OCBI and group cohesiveness (as well as the group member's OCBO and group cohesiveness) on his or her objective task performance change.     

Brief Exposure to Misinformation Can Lead to Long‐Term False Memories

Do false memories last? And do they last as long as true ones? This study investigated whether experimentally created false memories would persist for an extended period (one and a half years). A large number of subjects (N = 342) participated in a standard three‐stage misinformation procedure (saw the event slides, read the narrations with misinformation, and then took the memory tests). The initial tests showed that misinformation led to a significant amount of false memory. One and a half years later, the participants were tested again. About half of the misinformation false memory persisted, which was the same rate as for true memory. These results strongly suggest that brief exposure to misinformation can lead to long‐term false memory and that the strength of memory trace was similar for true and false memories.

No postnatal maternal effect on male aggressiveness in wild-derived strains of house mice

Male aggressiveness is a complex behavior influenced by a number of genetic and non-genetic factors. Traditionally, the contribution of each of these factors has been established from experiments using artificially selected strains for high/low aggressive phenotypes. However, little is known about the factors underlying aggressive behavior in natural populations. In this study, we assess the influence of genetic background vs. postnatal maternal environment using a set of cross-fostering experiments between two wild-derived inbred strains, displaying high (STRA, derived from Mus musculus domesticus) and low (BUSNA, derived from Mus musculus musculus) levels of aggressiveness. The role of maternal environment was tested in males with the same genetic background (i.e. strain origin) reared under three different conditions: unfostered (weaned by mother), infostered (weaned by an unfamiliar dam from the same strain), and cross-fostered (weaned by a dam from a different strain). All males were tested against non-aggressive opponents from the A/J inbred strain. Resource-holding potential was assessed through body weight gains and territory ownership. The STRA males were shown to be aggressive in both neutral cage and resident-intruder tests. On the contrary, the BUSNA males were less aggressive in all tests. We did not find a significant effect of postnatal maternal environment; however, we detected significant maternal effect on body weight with differences between the strains, fostering type and interactions between these factors. We conclude that the aggressiveness preserved in the two strains has significant genetic component whose genetic basis can be dissected by quantitative trait loci analysis.     

The Protective Effects of Religious Beliefs on Behavioral Health Factors Among Low Income African American Adolescents in Chicago

Religious involvement has long been argued to have protective effects for negative behavioral health outcomes for vulnerable youth. This study builds on the existing resilience literature and need for more studies that examine protective factors associated with behavioral health. A sample of 638 low-income African American adolescents in Chicago to examine within group variations of the influence of religious involvement on delinquency, school engagement, substance use and sexual risk behaviors, and whether such relationships differ by gender, sexual orientation, and socioeconomic status. Logistic regression findings documented that greater religious involvement was protective with regards to lower rates of delinquency, drug use, risky sexual behaviors and higher rates of school engagement, and that gender, sexual orientation and socioeconomic status varied for several of these relationships. Overall findings are discussed with regards to future research.
