The lattices of varieties were studied in many works (see [4], [5], [11], [24], [31]). In this paper we describe the lattice of all subvarieties of the variety defined by so called externally compatible identities of Abelian groups and the identity x n ≈ y n . The notation in this paper is the same as in [2]. Presented by W. Dziobiak  相似文献

The prevalence of most adult psychiatric disorders varies across racial/ethnic groups and has important implications for prevention and intervention efforts. Research on racial/ethnic differences in the prevalence of internalizing and externalizing symptoms and disorders in adolescents has been less consistent or generally lacking. The current study examined the prevalence of these symptom groups in a large sample of sixth, seventh, and eighth graders in which the three major racial/ethnic groups in the U.S. (White, Black, and Hispanic/Latino) were well-represented. Hispanic females reported experiencing higher levels of depression, anxiety, and reputational aggression than other groups. Black males reported the highest levels of overtly aggressive behavior and also reported higher levels of physiologic anxiety and disordered eating than males from other racial/ethnic groups. Hispanic females also exhibited higher levels of comorbidity than other racial/ethnic groups.  相似文献

This study examined what parents of children with disabilities and special needs found helpful about belonging to mutual support groups. Quantitative data (based on 56 parents from 6 groups) indicated that members found the groups very helpful and were very satisfied with the support they received from their groups; they also described the groups as high in cohesion, expressiveness, task orientation, and self-discovery. A grounded theory analysis of focus group data (based on 43 parents from 5 of the groups) indicated that such support was helpful in three broad domains: (1) the sociopolitical, which involved developing a sense of control and agency in the outside world; (2) the interpersonal, which involved asense of belonging to a community; and (3) the intraindividual, which involved self change. A central theme of identity change emerged as superordinate to these three categories.  相似文献

Nationalist and ethnic conflicts are a continuing source of tension in the post–Cold War period. The underlying factors affecting such conflicts are threat perception, ethnic security dilemmas, and lack of trust between nationalist/ethnic groups. The challenge is to find solutions to these conflicts. International institutions can establish trust and reduce the ethnic security dilemma by providing multiple forums of representation, promoting overlapping identities, and pooling sovereignty. Pooling sovereignty across a number of international representative bodies leads to increased access to governmental policymaking, with each party having a stake in government, and leads to a reduction in political tension and conflict. Thus, international parliamentary institutions may provide a solution to these conflicts. The British-Irish Peace Agreement (Good Friday Agreement) of 1998 is examined as an illustration of this argument.  相似文献

MAU程序和自由讨论的群体决策质量比较   总被引:5,自引:0,他引:5  
采用实验室研究方法,比较了在信启、不分享条件下多特征效用模型(MAU)决策程序和自由讨论对群体决策质量的影响,并对影响MAU决策质量的主要因素进行了初步探讨。结果发现:(1)MAU程序可以较好地克服群体动力学方面的一些消极影响,表现出挖掘信息(尤其是非分享信息)的充分性。但MAU程序在被试的态度和社会交互作用等心理效标上并未显示出优势;(2)在MAU条件下,群体规模的增大对分享和非分享信息的讨论量无显著影响。而任务难度效应要和群体规模一起才能起到作用。  相似文献

Examined relationships among social support, psychosocial competence, and adaptation to college in a sample of 357 African American, Asian American, Latino, and white college students. Social support and active coping were significant predictors of adaptation to college, whereas locus of control was not. However, there was an interaction between ethnicity and locus of control indicating that although internal African American, Latino, and white students had higher adaptation-to-college scores than external students, the opposite was true for Asian Americans. The relationships among social support, internality, and active coping were also explored. Satisfaction with social support and internality were positively related to active coping, but locus of control and social support were unrelated. Active coping and internality were significantly related to each other for all groups except for African Americans. Although most relationships were the same across groups, these findings call attention to the role of ethnicity as a moderator of college adjustment processes.  相似文献

The effect of 12-step mutual help groups (e.g., Narcotics Anonymous) on members' friendship networks has received little attention. This 1-year longitudinal study examined such effects in a sample of 2,337 male substance abuse inpatients, 57.7% of whom became significantly involved in 12-step activities (e.g., reading program literature, attending meetings) after treatment. An a priori model of the interplay of 12-step involvement and friendship networks was tested using structural equation modeling, and found to have excellent fit to the data. Twelve-step group involvement after treatment predicted better general friendship characteristics (e.g., number of close friends) and substance abuse-specific friendship characteristics (e.g., proportion of friends who abstain from drugs and alcohol) at follow-up. Results are discussed in terms of how mutual help group involvement benefits patients and how the self-help group evaluation paradigm should be broadened.  相似文献

为考察大学生民族文化认同与职业成熟度的关系及其内在心理机制,本研究采用多民族青少年文化认同问卷、大学生生涯自我效能感量表和大学生职业成熟度量表对4292名在校大学生进行测查,结果发现:(1)大学生的主流文化认同、民族文化认同、生涯自我效能感和职业成熟度之间具有明显的正相关;(2)主流文化认同--生涯自我效能感在民族文化认同与职业成熟度之间起链式中介作用;(3)生涯自我效能感中介民族文化认同与职业成熟度的关系在男生样本中不显著而在女生样本中显著;主流文化认同、生涯自我效能感分别单独中介民族文化认同与职业成熟度的关系在汉族大学生样本中为部分中介,而在少数民族大学生样本中为完全中介。  相似文献

This paper provides an overview of theory and research regarding problem construction and identification. Specifically, the paper reviews a theoretical model of processes associated with problem construction and empirical evidence in relation to the model. Finally, the paper reviews the literature on team problem construction.  相似文献

Since the introduction of brainstorming as an idea‐generation technique to address organizational problems, researchers have struggled to replicate some of the claims around the technique. One major concern has been the differences in the number of ideas generated between established groups as found in industry versus the non‐established groups used in the laboratory. The impact of group establishment on idea quality has also been an area of interest. This study addresses these issues by using a more in‐depth induction to establish groups and testing some discrepancies in the relationship between idea quality and idea quantity using 42 three‐person brainstorming groups. Results indicate that brainstorming groups, given an adequate amount of time (10 weeks) to become established, did generate more ideas and higher quality ideas than non‐established groups. Also, a relationship between idea quality and idea quantity was found. Further discussion of results and implications follows.  相似文献
