A computer-assisted language intervention, Fast ForWord-Language (FFW-L), was tested at a rural Nevada center in a group of children (Grades 2-12) referred by parents and teachers to assess enhancement of language skills. Given conflicting results from previous studies, language scores were measured using Clinical Evaluation of Language Fundamentals, Third Edition (CELF-3) before and after the FFW-L intervention. 58 children's CELF-3 postintervention scores were adjusted for age-specific expected changes and compared with pretest scores. Adjusted scores increased in both receptive and expressive domains of the CELF-3. Children with prior diagnoses of language and/or learning impairment did not differ from other referrals on adjusted CELF-3 adjusted gain scores after treatment. Thus the Fast ForWord-Language intervention may benefit a much broader group of children referred by parents and teachers for language or reading problems.  相似文献

Spotted hyenas (Crocuta crocuta) are gregarious carnivores. The females are socially dominant to males, and adult males rarely direct aggression toward adult females. This study analyzed all cases in which adult immigrant males behaved aggressively toward adult females in a large population of free‐living hyenas in Kenya, observed for 11 years. Our goals were to describe the conditions under which male attacks on females occur, and address possible adaptive functions. Most aggression directed by adult immigrant males against females occurred when coalitions of two or more males attacked a single adult female, who typically responded by defending herself and fighting back. Male aggression against females frequently occurred at sites of ungulate kills, but males never behaved aggressively toward females over food, and all male attacks on females were unprovoked. Although no mounting or other copulatory behaviors ever occurred during or immediately after an attack, the number of male attacks on females peaked around the time of conception. Daily rates at which males attacked females did not vary with female social rank. However, daily attack rates did vary significantly with female reproductive state, and the highest rates of male attack on females were observed during the two stages of the reproductive cycle during which females were most likely to conceive litters. The adaptive significance of male aggression against females in this species remains unknown, but a tight association between male attacks on females and a female's time of conception provides strong evidence of some role for male aggression in hyena sexual behavior. In particular, our data are consistent with hypotheses suggesting that male aggression toward females in this species either serves to inform females about male fitness or represents sexual harassment.

The purpose of this study was to examine the role of gender, sports participation, and gender orientation in predicting individuals' domain-specific and global self-esteem. A sample of 100 Grade 11 students completed measures of self-perception, body image, gender orientation, and sports participation. The results showed that although boys reported greater satisfaction with weight and appearance, there were no gender differences in general self-worth. In addition, more feminine individuals who participated in competitive sports reported lower levels of perceived athletic competence and global self-worth, but reported higher self-esteem when they participated in more noncompetitive sports. Although sports participation does predict self-esteem, participants' gender orientation and the type of sports in which they participate are moderating factors.  相似文献

Lesbian, gay, and bisexual (LGB) individuals encounter internal and external barriers that affect their mental health, and they continue to be underserved by the counseling profession. A counselor training seminar on sexual orientation is presented in this article. The seminar incorporated popular songs, readings, and class discussion to increase awareness of sexual identity development, stereotypes, and counseling interventions for LGB clients. Results of evaluations from the graduate counseling students suggest that the seminar had a positive impact on knowledge, interest, and attitudes.  相似文献

Teaching music in certain seminary contexts poses particular challenges for teaching and learning. The theme of disjuncture between teacher and student in courses that aim to incorporate music in the seminary curriculum are more vital than ever before because of the extreme cultural diversity of our population and integral nature of music in the worship life of religious communities. This essay tackles the difficulties associated with teaching worship music in seminaries where there are a plurality of religious traditions represented and a host of expectations held by diverse student bodies about what connotes worship music. Topics addressed include issues concerning terminology, repertoire, pedagogical methods for teaching worship music, and current issues in church music.  相似文献

Mothers of preschoolers in China and India reported on the value they accorded to items tapping two socialization goals, Filial Piety and Socioemotional Development and two parenting styles, Authoritative and Authoritarian. In both cultures, maternal valuing of Filial Piety was associated with greater exertion of parental control, whereas greater valuing of Socioemotional Development was related to more frequent use of Authoritative practices. However, patterns in relationships between Filial Piety, Socioemotional Development and Authoritative parenting differed across Chinese and Indian mothers. Positive associations were found among these three variables for Indian mothers, reflecting Hindu beliefs about young children and childhood. Among Chinese mothers, on the other hand, Filial Piety was negatively related with Socioemotional Development and the use of Authoritative practices. Our results suggest that Chinese mothers believe that the use of authoritative practices, which encourage socioemotional development in children, will inhibit achievement of filial behaviour and academic achievement. Contrasts between these two Asian cultures highlight the importance of considering parents' socialization goals and beliefs in cross‐cultural studies of child‐rearing practices.

This research identified 5 behaviors that may enhance the effectiveness of a diverse organization and used Fishbein and Ajzen's (1975) theory of reasoned action to identify predictors of these behaviors. Results from samples of White and Asian undergraduate students from 2 universities generally supported the Fishbein and Ajzen model. Attitudes and subjective norms were significant predictors of behavioral intentions when gender, race, and social desirability bias were controlled. Racial identity also had a significant, positive effect on attitudes toward diversity-related behaviors among the Asian American students, but no significant effect among Whites. These results supported our reasoning that members of historically excluded racial groups with strong racial identities will be most likely to welcome organizational attempts to become more pluralistic because pluralism means that their valued identities will be respected rather than repressed.  相似文献
