This paper examines the critical interface between manufacturing, purchasing, and quality assurance by exploring the impact of two alternative structures of buyer and vendor communication on attempts to improve the quality of purchased items. Those two structures of communication are the parallel structure and the serial structure. The research analyzes and compares the advantages and disadvantages of these two specific communication structures; the results have implications for both researchers and managers. The analysis of data suggests that the parallel structure is associated with significantly higher levels of quality than the serial structure. From a managerial perspective, the results of the research suggest that manufacturers must consider the parallel communication structure as a viable alternative for improving the quality of purchased components. While this study has helped frame some key managerial issues, the need and opportunity for further research in related areas is delineated. 相似文献

This study examined the potential risk and protective parental factors associated with depression among African American youth living in public housing. Utilizing a community-based participatory research approach, 239 African-American youth surveys were collected during 2013–2014 in two urban public housing developments with low socioeconomic profiles. Over half (52.3%) of the sample was in high school and female (58%). 65.3% reported living with their mother while 38% reported being employed. Bivariate analysis revealed significant correlations between depression and maternal substance abuse, paternal monitoring, parent-child relationship, and family time. Results from the regression analyses indicated that higher depression scores were significantly associated with youth who reported poor parent-child relationships, low levels of paternal supervision and high levels of maternal drug abuse. These findings provide support for claims about the importance of parent-child relationship and paternal monitoring as a protective factor for depressive symptoms, particularly during adolescence. Moreover, findings suggest that interventions which are targeted towards urban African American youth should address parental factors as a pathway to decrease depression among this population. 相似文献

Multilevel and relational views of leadership are expanding the focus of leadership development beyond individuals' knowledge, skills, and abilities to include the networked patterns of social relationships linking members of dyads and larger collectives. In this review, we present a conceptual model explaining how three distinct approaches for network-enhancing leadership development can improve the leadership capacity of individuals and collectives. We then present a review of the leadership development literature and the results of a survey of 282 practitioners to assess the extent to which these approaches have been examined in research and implemented in practice. Our review revealed that leadership research and leadership development practice are outpacing leadership development research in terms of incorporating networks. We aim to spur future research by clarifying the targets, objectives, and underlying mechanisms of each network enhancing leadership development approach in our conceptual model. Further, we identify additional literature, not traditionally considered within the realm of leadership development that may help advance empirical examinations of these approaches. 相似文献

Infant symbolic play was examined in relation to prenatal alcohol exposure and socioenvironmental background and to predict which infants met criteria for fetal alcohol syndrome (FAS) at 5 years. A total of 107 Cape‐Colored, South African infants born to heavy drinking mothers and abstainers/light drinkers were recruited prenatally. Complexity of play, sociodemographic and psychological correlates of maternal alcohol use, and quality of parenting were assessed at 13 months, and intelligence quotient and FAS diagnosis at 5 years. The effect of drinking on spontaneous play was not significant after control for social environment. In contrast, prenatal alcohol and quality of parenting related independently to elicited play. Elicited play predicted 5‐year Digit Span and was poorer in infants subsequently diagnosed with FAS/partial FAS and in nonsyndromal heavily exposed infants, compared with abstainers/light drinkers. Thus, symbolic play may provide an early indicator of risk for alcohol‐related deficits. The independent effects of prenatal alcohol and quality of parenting suggest that infants whose symbolic play is adversely affected by alcohol exposure may benefit from stimulation from a responsive caregiver. 相似文献

“Did You See What I Saw?” Gender Differences in Perceptions of Avenues to Prestige among Adolescents 总被引:1,自引:0,他引:1
We use data from 1,796 college students to explore gender differences in perceptions of avenues to prestige during adolescence. Students attending seven large universities during the 1997–98 academic year provided information on the ways in which adolescents in their high schools had gained prestige with peers. The analysis reveals substantial gender differences in perceptions regarding the most common avenues to prestige. Most important, men were less likely than women to report that female students in their high schools accrued prestige through sports and grades, and more likely than women to report that male students accrued prestige through engaging in deviant behaviors, such as sexual activity, drug and alcohol use, and fighting. We discuss the findings in the context of gender differences in social perception and gender-role attitudes. 相似文献

In two experiments, interpersonal status was experimentally manipulated by assigning one dyad member to be the owner of a mock art gallery and the other to be the owner's assistant. Without forewarning, participants were asked immediately following the interaction to recall their partner's hand gestures, self-touch, gazing, smiling, and nodding. Accuracy of recall was determined by comparing these ratings to their partners' behavior as coded from the videotape. In both experiments, assistants were more accurate at recalling the amount of owners' self-touch than vice versa, but there was little evidence of an accuracy difference in recall of the other nonverbal cues. When accuracy was defined as the correlation between a participant's ratings of the partner's behaviors and the partner's actual behaviors, there was evidence that assistants were more accurate than owners when a combined p-value was calculated across both studies. 相似文献

"We have described a method for reducing the dimensionality of the forecasting problem by parsimoniously modeling the evolution over time of the age schedules of vital rates. This method steers a middle course between forecasting aggregates and forecasting individual age specific rates: we reduce the problem to forecasting a single parameter for fertility and another one for mortality. We have described a number of refinements and extensions of those basic methods, which preserve their underlying structure and simplicity. In particular, we show how one can fit the model more simply, incorporate lower bounds to the forecasts of rates, disaggregate by sex or race, and prepare integrated forecasts of rates for a collection of regions. We also discuss alternate approaches to forecasting the estimated indices of fertility and mortality, including state-space methods. These many versions of the basic method have yielded remarkably similar results." (SUMMARY IN FRE) 相似文献
