The present study examined the relationship of child maltreatment to both emotion dysregulation and subsequent eating pathology. In an effort to extend previous research, the authors examined the unique impact of childhood emotional abuse (CEA) on emotion dysregulation and eating disorder (ED) symptoms while controlling for the effects of sexual and physical abuse. Structural equation modeling was utilized to simultaneously examine the effects of all three abuse types on multiple dependent variables as well as examine whether deficits in emotion regulation mediated the relationship between abuse and eating pathology. Results from a survey of 1,254 female college students revealed significant paths from abuse subtypes to specific eating disorder symptoms, with CEA evidencing the strongest association with ED symptoms. Additionally, emotion dysregulation was positively associated with ED symptoms, and mediated the effects of emotional abuse on symptoms. Findings support previous research on the enduring effects of emotional abuse as well as highlight the importance of the assessment of CEA in the treatment of ED symptoms. 相似文献

Students were linked virtually across three contexts: U.S., Malaysia, and China. Differences emerged in how student-created messages were constructed and interpreted; these impacted perceived relational affiliation. Messages constructed by students in Malaysia and China exhibited casual talk, greater self-disclosure, requests for personal information, and greater use of emoticons/emoji. Interactions were perceived as informal, friendly, and positive. U.S. students’ messages often showed institutional talk, less self-disclosure, and more attention to the instructor-assigned task. Asian-U.S. student pairs perceived their interactions as formal, less friendly, and less positive. This study shows how online technologies may be afforded and shaped by culture and interaction. 相似文献

This paper presents a solution to the problem of global exact output tracking for uncertain MIMO (multiple-input–multiple-output) linear plants with non-uniform arbitrary relative degree using output feedback sliding mode control. The key idea to overcome the relative degree obstacle is to generalize our previous hybrid estimation scheme to a multivariable version by combining, through switching, a standard linear lead filter with a non-linear one based on robust exact differentiators, achieving uniform global exponential practical stability and exact tracking. 相似文献

The online public access catalog consists essentially of a machine-readable database with network capabilities. Like other computer-based information systems, it may be continuously enhanced by the addition of new capabilities and databases. It may also become a gateway to other information networks. This paper reports the evolution of the Bibliographic Access and Control System (BACS) of Washington University in end-user searching, current awareness services, information management, and administrative functions. Ongoing research and development and the future of the online catalog are also discussed. 相似文献

As competition for students, faculty and financial support has increased, so has the application of marketing in the field of higher education. One critical application of marketing all too often neglected, misunderstood and mismanaged in higher education is targeting customers for profitability. The purpose of this paper is to enrich the marketing practices of academic institutions as they face increasing competition for students, faculty and funding by presenting a discussion of ‘right,’ ‘at-risk right’ and ‘wrong’ customers for higher education. This paper reviews marketing paradigms as they have evolved over time, explains the concepts of right, at-risk right and wrong customers as they apply to higher education and identifies managerial implications critical to today's higher education administrators. 相似文献

This article defines the problem of teaching foreign students in standard American university composition courses. It describes how two composition courses were modified to meet the needs of students who were beyond English as a Second Language composition but not yet ready for mainstream study. The article suggests that adaptations, not only in technique, but in approach and content as well, are required in order to fulfill the needs of these special students.Sally L. Chirinos, M.A. was the Academic Director of the EFL Program at the Instituto Cultural Peruano-Norteamericano, Arequipa, Peru from 1977–78. Suellen Rundquist is a M.A. candidate in Foreign Language Education and English as a Second Language at the University of Minnesota. Lisa Washburn holds a M.A. in English as a Second Language and a M.A. Germanic Philology from the University of Minnesota. 相似文献

ABSTRACTAre intra-national student flows driven by the same forces as international student mobility? This paper addresses this question by analysing cross-border student mobility in the UK. The paper identifies four principles that one might expect to drive the destination choices of students from Scotland enrolling in English universities. Following a statistical analysis of student destination choices, it is argued that cross-border moves from Scotland to England are stimulated by some of the same global forces as international student mobility (such as a desire to accumulate cultural capital), but in terms of destination choice the imaginaries held by Scottish students of ‘good’ places to study in England to accumulate cultural capital are constructed differently from the imaginaries of international students. 相似文献

In Experiment 1, male rats were exposed to either aggressive (i.e., alpha) or nonaggressive conspecific colonies and tested 24 h later, with or without alpha odors, for freezing behavior and burying of a wall prod that had been the source of a brief electric shock. The results indicated that prior defeat experience and the presence of alpha odors alone during testing had no significant effects, but the combination of prior defeat and alpha-odor testing significantly decreased burying and increased freezing behavior. In Experiment 2, we examined the effects of noncontact exposure to a cat, as a predatory Stressor, during subsequent prod-shock tests involving the presence or absence of cat odors. Exposure to a cat failed to disrupt later prod burying and did not produce freezing. However, the presence of cat odors during testing significantly reduced the amount of defensive burying,without resulting in an increment in freezing. In Experiment 3, rats were given 1, 5, or 30 inescapable preshocks in the presence of either cat odors or a hedonically neutral citronella odor and were tested 24 h later for prod burying and freezing with or without these odors. Both the cat and the citronella odors resulted in a significant reduction in burying and an increase in freezing for rats given 5 and 30 preshocks and tested in the presence of these respective conditioned odors. For the groups that were given 5 preshocks, preshock and later testing in the presence of cat odors resulted in significantly less prod burying and more freezing than for rats that were preshocked and tested in the presence of citronella. The findings of these three ethoexperimental studies are discussed in terms of the learned-helplessness theory, the stress-coping-fear-defense (SCFD) theory, and the concept of selective CS-US associability. 相似文献
