Although empirical work has examined differences between salesmen and saleswomen on various aspects, no comprehensive study has examined gender-based distinctions in salespeople's work motivation. The paucity of research attention on this topic is surprising given the plethora of literature in organizational behavior. This paper reports the results of an investigation that explored male and female salespeople's perceptions of expectancies, instrumentalities, and valence for rewards. Findings reveal minimal contrast between the two groups. Implications for practitioners and researchers are provided.  相似文献

The surge in the rate of the Human Immunodeficiency Virus (HIV) and Acquired Immunodeficiency Syndrome (AIDS) cases continues to be most prevalent for African American women between the ages of 18 and 29, with heterosexual transmission remaining the primary cause of HIV spread for this population. The high rates of HIV/AIDS among African American women continue to emphasize the need for understanding how members of this population conceptualize sexual safety and risk. A qualitative research study using grounded theory methods was conducted to explore how African American women define safer and risky sexual behaviors. Interviews were conducted with 14 African American women between the ages of 18 and 29. The study findings suggest that African American women’s definitions of safer and risky sexual behaviors, while in a consensual sexual relationship, are consistently influenced by sex partner type. The information garnered from this study can help inform the development of HIV prevention strategies, health education, counseling and reproductive health services that support African American women’s wellness.  相似文献

If perspective views of an object in two orientations are displayed in alternation, observers will experience the object rotating back and forth in three-dimensional space. Rotational motion is perceived even though only two views are displayed and each view is two-dimensional. The results of 5 experiments converge on the conclusion that the perception of apparent rotational motion produces representations in visual memory corresponding to the spatial structure of the object along its arc of rotation. These representations are view-dependent, preserving information about spatial structure from particular perspectives, but do not preserve low-level perceptual details of the stimulus.  相似文献

This article is a response to Coyne, Thompson, Palmer, Kagee, and Maunsell's (2000) article, “Should We Screen for Depression? Caveats and Potential Pitfalls.” We address four points that we view as central to their argument: (1) current screening measures are inadequate; (2) correct identification of depressed patients does not result in improved clinical outcomes; (3) screening is too expensive; and (4) screening may have harmful negative effects. We discuss the following important issues: (1) screening and prevention are still in the research and development phase; (2) the kindling phenomenon is an important reason to screen; (3) there is a need to focus screening and prevention efforts on ethnic minorities; and (4) high depressive symptoms have a substantial public health impact. Finally, we present reasons why screening is advisable, both for prevention and treatment purposes, and provide our recommendations. Our stance is that, in order for screening and prevention to become practical, they need to be implemented in both research and practice contexts. Therefore, we should make screening for major depression a priority.  相似文献

Service delivery efforts to attenuate the risks associated with parenting premature infants in poverty often are compromised because those at greatest risk do not use available parenting support services. Yet, relatively little is known about the networks of support surrounding these parents. This study investigated both the characteristics of informal social support within a sample of 31 low‐income, African American mothers of premature infants at high risk for parenting difficulties and their use of community parenting support services. The findings suggest that mothers had small (M = 4.97, SD = 1.80), but highly mobilized, social support networks consisting primarily of family members. Among six different types of support, informational guidance and parenting support were available from the fewest people in participants' networks. Only 32.3% of the sample was aware of and 16.1% of the sample had ever used formal parenting support services. Participants who had received informal support from more than five people in the last month were significantly more likely to have knowledge about existing community parenting support services than those receiving support from smaller social networks. Patterns of knowledge about and utilization of services were examined with regard to network characteristics, perceived maternal desire for more parenting support opportunities than were available, and presence of special needs in the child. The implications of these findings for parenting support programs are discussed. ©2002 Michigan Association for Infant Mental Health.  相似文献

We analyzed data from 87 mothers of children ages 15 to 44 months with cerebral palsy (CP) or no diagnosis, who completed the Dyadic Adjustment Scale, Parenting Stress Index, Support Functions Scale, and Inventory of Social Support. Principal components analysis of the 15 subscales from the 5 measures revealed few cross-measure loadings. Mothers of children with CP (severe or mild) reported higher levels of parenting stress than did mothers of controls. However, cluster analysis of self-report measures yielded a 5-cluster solution, with no diagnostic group differences across clusters. That is, there were no overall differences in self-reported family functioning according to presence or severity of the child's disability. The results are discussed in terms of the organization of family systems and their relationship to child diagnosis. Clinical implications for assessing and working with families are noted.  相似文献
