This investigation concerned the socialization experiences and coping strategies of a group of 28 deaf adults who were raised using spoken language. Most respondents reported some level of social isolation because of (1) limitations in communication with hearing peers; (2) missing information in social, academic, and work settings; and (3) a sense of being "different." Most participants also reported strategies used to reduce isolation and mitigate the social difficulties associated with their hearing loss. 相似文献

The theory of transient operations of synchronous machines—the so called two-reaction theory—was developed during the years 1926–1938. Doherty, Nickle and Park made the first efforts to find a complete theory. The problem then was solved by Kron for a general rotating electrical machine. In this paper the two-axis-model-machine is described using a bond graph. An example is given in which state-space-equations and output-equations are derived from the bond graph. A power-conserving transformation between the electrical quantities of the armature windings of the model machine and those of the real three phase armature windings is developed. This transformation is shown as a displacement modulated transformer structure which is central to the bond graph model. 相似文献

Single parents, stepparents, and the susceptibility of adolescents to antisocial peer pressure 总被引:2,自引:0,他引:2
L Steinberg 《Child development》1987,58(1):269-275
According to a recent report, adolescents living in single-parent households are more likely to engage in deviant activity than are youngsters living with both natural parents, or in single-parent, extended households, allegedly because the presence of an additional adult provides greater control of youngsters' behavior. In the present study, fifth, sixth, eighth, and ninth graders from 1 of 3 family structures (both natural parents, mother alone, or 1 natural parent and a stepparent) were compared with respect to their susceptibility to peer pressure to engage in deviant activity. All comparisons controlled for sex, age, socioeconomic status, maternal employment, and patterns of family decision making. Youngsters living with both natural parents were less susceptible to pressure from their friends to engage in deviant behavior than youngsters living in other family structures. More important, youngsters growing up in stepfamilies--in the presence of an additional adult--were equally at risk for involvement in deviant behavior as were their peers growing up in single-parent households. 相似文献

Both sound management practice and the law require that administrative decisions affecting faculty members reflect systematic, uniformly applied, fair, and valid evaluations of performance. To meet these requirements a performance evaluation scheme must involve two decision elements, both of which are addressed and illustrated in this paper:what will be evaluated, andhow the evaluation will be made.A data-based faculty performance evaluation program specifically oriented toward such administrative actions as tenure, promotion, and salary adjustment is described. This program rests upon task analysis to clarify the nature of the desired evaluative content and peer review as the primary evaluative mechanism.The scheme is illustrated using the experience of a department of psychology training to the doctorate. However, the approach to faculty performance evaluation herein described and illustrated is generalizable, with modification, to other departments and institutions. Several considerations pertinent to such modification are discussed. 相似文献

Ethnicity and Community Context as Moderators of the Relations between Family Decision Making and Adolescent Adjustment 总被引:7,自引:0,他引:7
This study investigated whether the impact of 3 types of family decision making on the adjustment of 14–16-year-old youth was moderated by ethnicity, community context, or both. For joint and unilateral youth decision making, community context interacted with ethnicity in 3 patterns of influence: for Hispanic-American youth, variations in decision making had a stronger impact in ethnically mixed than in predominantly white communities; for African-American youth, the negative impact of unilateral youth decision making was stronger in predominantly white communities; and for Asian- and European-American youth, community context did not make a difference. For unilateral parental decision making, the popular hypothesis that apparent ethnic differences in the influence of parental strictness on adolescent adjustment are primarily due to differences in community context was not supported. Rather, the positive impact of unilateral parental decision making was similar among African-American youth living in predominantly white, and more affluent, communities or in more disadvantaged, ethnically mixed neighborhoods. The negative impact of authoritarian parenting was similar among European-American youth living in less advantaged communities as well as more affluent ones. There was no relation between unilateral parental control and adolescent adjustment of Asian- or Hispanic-American youth in either type of community. 相似文献

The performance of two-sample non-parametric detectors using dependent samples is considered. It is shown that in the situation in which square-law envelope detection is employed, the signals to be detected fluctuate in accordance with a chi-square distribution and the background interference is additive Gaussian noise; the two-sample Generalized Sign (GS), Mann-Whitney (MW), Modified Savage (MS) and Modified Rank Square (MRS) detectors have superior asymptotic processing times to those that are obtained when independent samples are used. Also, it is shown that in addition to the advantage of improved performance, detection using dependent samples can have implementation advantages as compared with detection based on the use of independent samples. 相似文献
