This article examines the extent to which the 2006 revisions to the EU's Generalised System of Preferences improved market‐access opportunities for developing‐country agro‐food exports. It shows that they resulted in only a slight increase in the percentage preferential margin, but that there has been a significant increase in the value of preferential trade and of the preferential margin enjoyed by exporters. This was accompanied by changes in the ranking of beneficiaries. Countries such as China, Brazil, Argentina, India and South Africa maintained their significant shares of GSP agro‐food exports, but other countries such as Thailand and Vietnam have now emerged as major GSP beneficiaries.  相似文献

This article examines whether social class differences influences low-income, married and cohabiting African Americans to realize that they are in a “coupled” relationship. To determine the extent to which social class influences the assessment of “couple” status in these partnerships, we examined the qualitative responses of 30 cohabiting and 31 married African Americans to a question regarding the specific event in their relationship that made them realize they were a couple. Qualitative analyses of the data resulted in four delineated themes: (1) relationship marker, (2) affection/sex, (3) having or rearing children, and (4) time and money. Supporting qualitative data are presented in connection with each theme. The sociological aspects of income on African American romantic relationships are also discussed.  相似文献

This study investigated how married and cohabiting African Americans define and experience emotional closeness and commitment because these processes have been shown to be directly linked to relationship stability. Thirty married and 30 cohabiting African American couples participated. Couples were between the ages of 21 and 45 years and had been in their relationship between 3 and 15 years. Interviews were conducted with the couples in their homes and were aimed at yielding a co-construction of couples’ views of these constructs. Specifically, this co-construction involved an examination of the ways men and women in married and cohabiting relationships define and experience emotional closeness and commitment. Special attention was devoted to examining the themes elicited from these interviews and illuminate the specific ways in which married and cohabiting African American couples consider emotional closeness and commitment. In general, few differences were apparent in their perceptions of emotional closeness. However, married couples were more likely to report that commitment played a large role in their decision to be together. Conversely, cohabiting couples expressed different views of commitment, often stating that commitment played a minimal role in their relationship or that they experienced commitment in ways that were not linked to the legal affirmation of their relationship. Implications for future research and practice include the importance of pinpointing the individual and cultural deterrents that affect the relationship stability of low income African American couples.  相似文献

Despite growing cohabitation rates, few studies have examined the relationship between engagement status and relationship quality among cohabiting couples, especially among Black Americans. This study used data from 30 cohabiting Black couples (n = 60) to examine whether perceptions of love, commitment, relationship satisfaction, and intimacy problems differ by whether cohabitors are engaged to be married. Results indicated that engaged Black cohabitors reported higher love scores than non-engaged Black cohabitors. They also had slightly more intimacy problems, but only in bivariate models. There were no significant differences in commitment or satisfaction between engaged and non-engaged Black cohabitors. Additional analyses revealed no variation in effect of engagement on relationship quality by gender. Results suggest that practitioners and policymakers should be careful not to make assumptions about relationship quality according to engagement status or gender in cohabiting Black relationships. The meaning and implications of engagement among cohabiting Black Americans may be changing.  相似文献

Mental health services are a core component of child advocacy centers in the United States. Child advocacy center directors were surveyed about (a) trauma and posttraumatic stress disorder; (b) referral criteria for treatment of abuse victims; (c) evidence-based treatments for abused children; (d) reliable, valid, and normed measures helpful in assessment; and (e) training needs. Directors accurately identified posttraumatic stress disorder symptoms, but additional symptoms were misidentified. Directors identified best practices for assessment and treatment, but they misidentified non-evidence-based practices. Primary reasons for referral for services included severity of abuse and emotional response of the child. However, referrals based on assessment findings were not a high priority. Directors expressed some training needs for staff consistent with issues identified in the study.  相似文献

Scholars have suggested that family life may influence children's attributions about close relationships. Using a sample of 369 two‐parent families with 2 children (a target adolescent in the 8th grade and a sibling aged 10 to 18), we investigated whether the sibling's negative attributions regarding the target adolescent were associated with mother's and father's negative attributions regarding the target adolescent, or the gender constellation and birth order of the sibling pair. In addition, we used the self‐reported negative attributions of both siblings and adolescents to investigate whether attributions predicted one's own behavior, or whether the behavior of the partner predicted the perceiver's negative attributions. Structural equation models showed that mothers' and fathers' negative attributions regarding the target adolescent predicted concurrent negative attributions for girls, but not boys. In addition, siblings' negative attributions regarding each other predicted their negative and positive behavior toward the partner 2 years later. The positive behavior of the attribution target also predicted the perceiver's negative attributions, but its effect was weaker. Girl sibling pairs were less negative in their attributions than cross‐sex sibling pairs and boy sibling pairs. Finally, although younger siblings were less negative in their attributions than older siblings, this difference decreased over time. This study advances the knowledge of negative attributions in close relationships by identifying family correlates of an understudied, but important, close relationship.  相似文献

Information derived from interim sacrifices or on cause of death is routinely used in the statistical analyses of carcinogenicity experiments involving occult tumours. The authors describe a simple semiparametric model which does not require this information. Natural deaths during the experiment and the usual terminal sacrifice provide sufficient information to ensure that the tumour incidence rates, which are of primary interest in occult‐tumour studies, can be estimated nonparametrically. The advantages of this semiparametric approach to the analysis of survival/sacrifice experiments are illustrated using data from a study on benzyl acetate conducted under the U. S. National Toxicology Program. The results derived compare favourably with those obtained using a previously published approach to the analysis of tumorigenicity data.  相似文献

情绪智力是当代心理科学中最难界定的概念之一。虽然在过去的近20年里,人们从多角度对情绪智力进行研究并取得许多有益的结果,但迄今为止仍有许多重大问题悬而未解,其中就包括情绪智力的概念化问题。在系统分析和梳理已有情绪智力概念化研究的基础上,较为清晰地阐述了人们在情绪智力概念化研究上所取得的五个共识、存在的五个争议以及今后需要进一步研究的六个问题,以期促进情绪智力研究的深入。  相似文献
