Many will ask what Harlem finds to honor in the stormy, controversial and bold young captain. And we will smile. And we will answer and say unto them: Did you ever talk to Brother Malcolm? Did he ever touch you? Did you have him smile at you? Did he ever do a mean thing? Was he ever himself associated with violence or any public disturbance? For if you did, you would know him and if you knew him you would know why we must honor him. 相似文献

A case study analyzed employees' attitudes toward, and experiences with, an intraorganizational electronic mail system. Results revealed that females perceived e-mail to be easier to use, more efficient, and more effective than males. They also gave higher ratings of appropriateness for using e-mail to transmit certain types of messages. Females (particularly managers) were more likely than their male counterparts to rely on co-workers to learn how to use e-mail. More females used the computer system for word processing, while more males and whites (who comprised 82.2% of the sample) had off-site connections to the computer system. No other distinctions were found regarding race—ethnicity. Implications for future research are discussed.The author is grateful to Karen Tracy, Robert Craig, and anonymous reviewers for their insights and suggestions. 相似文献

“My big sister the town supervisor”: Family leadership training is not just for boys 总被引:1,自引:0,他引:1
This study investigates gender similarity in the effects of birth order upon political leadership. Town supervisors were the leaders studied as there are a considerable number of women who attain this level of leadership. Questionnaires about birth order and family size were gained from 66 women who were town supervisors in New York State in 1992, and compared to a randomly selected sample of 57 male town supervisors. It was found that women as well as men town supervisors were more likely to have been first born in their families. However, whereas gender does not apparently influence the relevance of birth order for leadership, it clearly does exert an influence on the level of political leadership attained. Women town supervisors gained their positions in towns that were considerably smaller than the towns led by the male supervisors. Discussion concerned the nature of family experiences that contribute to leadership training, including those that may be different for girls and boys. Further research is needed to clarify barriers to female assertion of political leadership at more senior levels, because as this study shows, female leadership is being trained in families. 相似文献

This process evaluation study examined what variables moderate and mediate treatment effects on days in stable housing and
client satisfaction for homeless mentally ill clients. In general, demographic characteristics did not moderate either outcome
variable. Housing contacts, entitlement contacts, mental health contacts, and supportive services were significant mediators
of the treatment effect on days in stable housing. Program contacts, mental health contacts, and supportive services were
significant mediators of client satisfaction.

by the staffs of Malcolm Bliss Mental Health Center, St. Patrick's Center, the Community Advocacy and Support Alliance Program,
and the St. Louisemergency shelters. Finally, we thank all of the participants in this study; we hope that their homelessness has now ended. (The conclusions

Abstract— Infants' auditory detection thresholds are higher than adult thresh olds. Since adults listen selectively for an expected test tone frequency, and selective listening improves their detection performance, one hypothesis about why infant thresholds are high is that infants do not listen selectively. This hypothesis was tested by obtaining listening bands from adults and from 7- to 9-month-old infants. The results replicate earlier findings that adults listen selectively but indicate that infants do not. Lack of selective listening likely contributes to infants' high thresholds. Further, the finding that infants and adults have different listening strategies has implications for infants' auditory perception in general. 相似文献

Eighty-two per cent of all cases of abuse or neglect of an adult with mental retardation substantiated by the Abuse Investigation Division of the Connecticut Office of Protection and Advocacy for Persons with Disabilities over a five-year period occurred in the victim's residence. Chi square analyses revealed that there was significantly more abuse in institutions and group homes and significantly less in the individual's own home. Furthermore, analyses revealed that there was significantly more personal neglect in group homes and community training homes and significantly less in own homes. The results were discussed and recommendations made regarding ways of reducing abuse and neglect. 相似文献

A running-wheel-movement-detection system is described for use with an IBM-compatible system and a serial mouse. It is an adaptation of a system developed for use on a Commodore 64. The IBM-compatible system provides obvious advantages in speed, memory, data storage, and programming ease over the earlier Commodore 64 system. 相似文献
