Transformational leadership and ambidexterity in the context of an acquisition

This study explores the role of transformational leadership and the values incorporated in a learning culture in promoting ambidexterity (the ability to explore new capabilities while exploiting existing ones) in teams involved in acquisition integrations. Data from a field study of an acquisition integration (N = 71 work teams) support hypotheses arguing that transformational leadership behaviors and the development of a learning culture, characterized by psychological safety, openness to diverse opinions, and participation in decision making, promote ambidexterity at the team level. We also found support for the association between transformational leadership and learning cultures.     

BRINGING CLIENTS BACK IN:

Using qualitative data from a cohort sample of 76 current or former Wall Street professionals, I argue that the perception that clients prefer homophily with their service providers shapes Wall Street careers and contributes to gender inequality. I also reveal how some women on Wall Street partially insulate themselves from biases against them by deliberately avoiding positions that are most dependent on client relationships. I hypothesize that the strength of client preferences for homophily in service providers in the Wall Street context is related to the high status of this service profession and its clients.     

A Semiparametric Approach to Risk Assessment for Quantitative Outcomes

Characterizing the dose-effect relationship and estimating acceptable exposure levels are the primary goals of quantitative risk assessment. A semiparametric approach is proposed for risk assessment with continuously measured or quantitative outcomes which has advantages over existing methods by requiring fewer assumptions. The approach is based on pairwise ranking between the response values in the control group and those in the exposed groups. The work generalizes the rank-based Wilcoxon-Mann-Whitney test, which for the two-group comparison is effectively a test of whether a response from the control group is different from (larger than) a response in an exposed group. We develop a regression framework that naturally extends this metric to model the dose effect in terms of a risk function. Parameters of the regression model can be estimated with standard software. However, inference requires an additional step to estimate the variance structure of the estimated parameters. An effective dose (ED) and associated lower confidence limit (LED) are easily calculated. The method is supported by a simulation study and is illustrated with a study on the effects of aconiazide. The method offers flexible modeling of the dose effect, and since it is rank-based, it is more resistant to outliers, nonconstant variance, and other departures from normality than previously described approaches.     

Detecting ongoing intimate partner violence in the emergency department using a simple 4-question screen: the OVAT

We wanted to prospectively evaluate the use of a brief screening tool for ongoing intimate partner violence (IPV), the OVAT, and to validate this tool against the present Index of Spouse Abuse (ISA). The design was a prospective survey during randomized 4-hour shifts in an urban emergency department setting. The scale consists of four questions developed based on our previous work. The ISA was compared as the gold standard for detection of present (ongoing) IPV. Of 362 eligible patients presenting during 75 randomized 4-hour shifts, 306 (85%) completed the study. The prevalence of ongoing IPV using the OVAT was 31% (95% CI 26% to 36%). For the ISA, the prevalence was 20% (95% CI 16% to 25%). Compared with the ISA, the sensitivity of the OVAT in detecting ongoing IPV was 86%, specificity 83%, negative predictive value 96%, positive predictive value 56%, with an accuracy of 84%. In conclusion, four brief questions can detect ongoing IPV to aid in identifying the victim.     

Exploring the Role of Working Memory in Dynamic Social Cue Decoding Using Dual Task Methodology

Decoding nonverbal social cues involves skills such as understanding emotions and discerning kin relationships. Social cue decoding has been described as an automatic process which does not tax cognitive resources. However, clinical deficits in social decoding are often interpreted in terms of deficits in attention and working memory. Two experiments are described which used dual task methodology to investigate the role of working memory in dynamic social cue decoding tasks: the Interpersonal Perception Task (IPT, Experiment 1) and the Profile of Nonverbal Sensitivity (PONS, Experiment 2). Results revealed that decoding social cues from the IPT did not require working memory resources, while social perception in the PONS made heavy demands on working memory. Implications for theoretical interpretation of these tasks and their use in clinical populations are discussed.

Eating disorders and body image of undergraduate men

Eating disorders and body dissatisfaction among undergraduate men are less documented and researched than are eating disorders and body dissatisfaction among undergraduate women. OBJECTIVE AND PARTICIPANTS: In this study, the authors examined these issues in undergraduate men to identify similarities and differences between this population and undergraduate women. METHODS: In a random sample of undergraduates, the authors categorized respondents by gender and by presence or absence of an eating disorder. The authors compared undergraduate men with an eating disorder with (1) undergraduate women with an eating disorder and (2) undergraduate men without an eating disorder. RESULTS: The patterns of responses suggest that undergraduate men with an eating disorder are preoccupied with body shape and tone but not necessarily with losing weight. CONCLUSIONS: The authors discuss implications for future prevention as well as clinical and research efforts based on male symptoms within the diagnostic category of bulimia nervosa and eating disorder, not otherwise specified.     

Impact of a multidimensional intervention programme applied to families at risk for child neglect

The purpose of this study is to evaluate the effects of an intervention programme applied to families at risk for child neglect. Twenty‐nine families were recruited through a Local Community Services Centre (LCSC) and were assigned to two groups: (1) the first group participated in a multidimensional eco‐systemic intervention programme called the Personal, Family and Community Help Program (PFCHP); and (2) the second group underwent psychosocial intervention that was provided as part of regular LCSC services and focused mainly on the social worker–family relationship. Pre‐test measures were obtained at the beginning of intervention for both groups and a follow‐up was held 24 months later. Quantitative and qualitative analyses indicated that both forms of intervention were associated with improved parent–child relationship and the reduction of parental stress, depression and the potential for child abuse and neglect. However, PFCHP participants showed multiple indications of improvement in their social and marital relationships, which was not the case for LCSC participants. The conclusion outlines the need for a long‐term intervention process for families at high risk for child neglect and the necessity of addressing multiple dimensions of family life if lasting changes are to be expected.
