Highly pathogenic avian influenza (HPAI) is considered one of the most important diseases of poultry. During the last 9 years, HPAI epidemics have been reported in Asia, the Americas, Africa, and in 18 countries of the European Union (EU). For that reason, it is possible that the risk for HPAI virus (HPAIV) introduction into Spain may have recently increased. Because of the EU free‐trade policy and because legal trade of live poultry was considered an important route for HPAI spread in certain regions of the world, there are fears that Spain may become HPAIV‐infected as a consequence of the legal introduction of live poultry. However, no quantitative assessment of the risk for HPAIV introduction into Spain or into any other EU member state via the trade of poultry has been published in the peer‐reviewed literature. This article presents the results of the first quantitative assessment of the risk for HPAIV introduction into a free country via legal trade of live poultry, along with estimates of the geographical variation of the risk and of the relative contribution of exporting countries and susceptible poultry species to the risk. The annual mean risk for HPAI introduction into Spain was estimated to be as low as 1.36 × 10−3, suggesting that under prevailing conditions, introduction of HPAIV into Spain through the trade of live poultry is unlikely to occur. Moreover, these results support the hypothesis that legal trade of live poultry does not impose a significant risk for the spread of HPAI into EU member states.  相似文献

Many gay men in the popular sectors of Lima, Peru participate in vóley callejero, or street volleyball. The ethnographic data presented in this article describes verbal and corporal mechanisms through which gay identity emerges within the particular context of the street volleyball game, ultimately highlighting the contextual nature of identity. The volleyball players are not just hitting a ball back and forth, they are engaging in a meaningful activity that illuminates intersections of language, sexuality, and identity. Through the manipulation of the street into a volleyball court, the volleyball players create a space conducive to the articulation of particular verbal and embodied practices that index gay identity. The challenge to the regulations of "proper" volleyball through the practice of ritual insulting and the cultivation of gay volleyball technique are playful reconfigurations of gendered practices prominent in the sites where fieldwork was carried out.  相似文献

This study investigated youth's modeling of and deidentification from parents in romantic relationships using two phases of data from adolescent siblings, mothers, and fathers in 246 Mexican‐origin families. Each parent reported his and her marital satisfaction and conflict, and youth reported on parent–adolescent warmth and conflict at Time 1. Youth's reports of modeling of and deidentification from their mothers and fathers and three romantic relationship outcomes were assessed at Time 2. Findings revealed that higher parental marital satisfaction, lower marital conflict, and higher warmth and lower conflict in parent–adolescent relationships were associated with more modeling and less deidentification from parents. Moreover, higher deidentification was linked to a greater likelihood of youth being involved in a romantic relationship and cohabitation, whereas more modeling was linked to a lower likelihood of cohabitation and older age of first sex. Discussion underscores the importance of assessing parental modeling and deidentification and understanding correlates of these processes.  相似文献

This study is a multi-national follow-up to the original (Sandberg and Knestel (2011) Journal of Marital and Family Therapy, 37, 393–410) article on the process of learning Emotionally Focused Couples Therapy (EFT). A total of 102 clinicians from nine Spanish-speaking countries (Mexico, Costa Rica, Guatemala, Spain, Colombia, Argentina, Chile, Ecuador, and El Salvador) participated in the study. A comparison of results across the two studies revealed more similarities than differences. However, a few notable differences emerged from responses to qualitative questions, namely a heightened sense of appreciation for and resonance with the focus on core emotion in EFT and less frequent reports of difficulty learning and adapting to the model among Spanish-speaking therapists. These differences were consistent with common cultural values and forms of expression in Latin America and Spain. Results are discussed in terms of training, supervision, and future research as well.  相似文献

There has been very little work on the impact of rainfall on migration from Mexico or even elsewhere. We use satellite data from NASA to examine the effect of the lagged level of rainfall relative to an area's historical average, on migration from small Mexican communities to the United States. Controlling for the level of education, proportion married, and historic migration levels, we find higher levels of rainfall significantly reduce Mexican migration to the United States and a 20 percentage point higher‐than‐normal level of rainfall leads to a predicted 10.3 percent decrease in migration.  相似文献

This article puts together all available data on contraceptive prevalence and effectiveness from 1968-83 in an attempt to assess the Philippine family planning program's performance in reducing fertility. 3 indicators of contraceptive effectiveness are discussed -- Pearl pregnancy rates, 12-month continuation rates, and effective protection level. Findings on factors associated with contraceptive prevalence are presented and discussed, with special emphasis on the effects of the Outreach project variables. The argument is that popualtion programs can influence demographic behavior, but the extent of this influence largely depends on the quality of program design and implementation.  相似文献

Abstract Alabama's forest products industry plays a dominant role in the state's rural economy. Examination of how access to employment opportunities is distributed provides insight into how the benefits of this industry are distributed. Based on a combination of available secondary data and semi-structured interviews with management and workers in the pulp and paper sector of Alabama's forest products industry, a clear picture of segmented labor markets emerges in which structural and cultural factors determine access to certain jobs. The evolution of these highly segmented labor markets is traced from deep roots in racial discrimination to contemporary efforts in support of affirmative action. Increased use of sub-contracting in logging, hauling, and mill work represents the most recent change affecting the structure of labor markets associated with the production of pulp and paper.  相似文献

The two paradigms for analyzing immigrant experiences, “assimilationist” and “transnationalist,” leave unanalyzed important differences in immigrant adaptation rooted in different historical generational experiences. This article analyzes the importance of a historically grounded generational frame of analysis. It captures differences in views and involvements between two cohorts of first generation émigrés. Empirically, the study focuses on different Cuban‐American cohort crossborder ties. The first cohort, comprised of émigrés who left between 1959 and 1979 primarily for political reasons, publicly oppose travel to Cuba because they believe it helps sustain a regime they wish to bring to heel. The second cohort, who emigrated largely for economic reasons, is enmeshed in transnational ties that, paradoxically, are unwittingly doing more to transform Cuba than first wave isolationism. The cohort comparison is based on interviews with émigrés in Union City, New Jersey and Miami, Florida. The analysis of effects of transnational ties rests on interviews in Cuba as well.  相似文献
