This article tests the relationship between the ratification of International Labour Organization (ILO) Conventions and the provision of unemployment benefits. Statistical tests focus on two related issues: why countries ratify ILO Conventions on unemployment benefits, and whether ratification influences government spending on unemployment benefits. The main findings are that democracy, region, income, and globalization are the main factors influencing why countries ratify ILO Conventions on unemployment benefits. In turn, the ratification of ILO Conventions is systematically associated with higher spending if countries have ratified more than two Conventions. 相似文献

The principal objective of this study is to determine whether battered women’s purpose of life (meaning/value) affects resilience (self‐efficacy/communication efficiency/optimism). This purpose is meaningful in that it may help provide battered women with a new perspective of a changeable life, away from the negative perspectives frequently associated with domestic violence sufferers. The subjects of this study were 110 battered women staying at shelters located in Seoul and Gyeonggi Province, Korea. The survey was conducted between August 15 and September 20, 2010. The data were collected using questionnaires measuring sociodemographic variables, a purpose‐of‐life scale, and a resilience scale. The collected data were evaluated with frequency, correlation, and multiple regression analysis. The results of this study can be summarized as follows. First, the meaning and value of life positively influenced self‐efficacy. Second, only the meaning had a beneficial effect on communication efficiency. Third, only the value variable positively affected optimism. Therefore, this study implied that resilience is an important area in the context of spousal abuse. Based on these results, a program for enhancing the meaning of life is suggested to help domestic violence survivors to build up resilience. 相似文献

This study expands immigrant social network theory and examined employment patterns in the garment industry in Los Angeles, California, among Latino workers employed by Asian immigrant entrepreneurs. The study determined that a large percentage of immigrant employees found their jobs through the immigrant economy. Entrepreneurship increased the supply of local jobs and expanded the economy at destination at no expense to natives. Immigrant entrepreneurs bought firms from nonimmigrant owners or started new ones with an immigrant labor supply. Massey's index is flawed due to its exclusion of the role of entrepreneurs. Migration networks facilitate entrepreneurship, but some ethnic groups have fewer entrepreneurs, such as Mexicans and Central Americans. A 1993 Los Angeles survey identified 3642 garment factories in its county. Mean employment was 27.1 persons. The garment industry was the 4th largest industry in the area in 1996, with 98,700 employees. It represented 6% of all wage and salary employees in the City and 5.5% of the immigrant labor force in the County in 1990. 93% of garment workers in 1990 were immigrants. It is estimated that 51% of garment factory owners were Asians; most employees were Latinos. Census figures on sewing machine operators indicated 47.3% of owners were Whites and 42.45 were Asians. 53.3% of employees were other ethnic groups, 14.5% were Asians, and 32.2% were Whites. It is estimated that 47.2% of total employment was due to the immigration economy. 71.5% of the total employment in the garment industry was in the immigrant sector. 相似文献

AbstractThe promise of digitalization is enormous and nowhere is it more critical than in its potential to transform food supply chain. Consumers have become more educated and are demanding real-time updated information on foods they consumed through digital media. They are also increasingly demanding to know if the foods they consume are environmentally and socially sustainable or not. As a result, food product traceability, safety, and sustainability issues have become crucial concerns to food retailers, distributors, processors, and farmers. Digitalization allows food supply chains to be highly connected, efficient, and responsive to customer needs and regulation requirements. However, digitalizing a traditional food supply chain is challenging and resource demanding. This is more so for developing countries where moving food from farms to consumers can take months as it travels through an array of middlemen. Unfortunately, little is available in the existing literature on food supply chain digitalization. So far, current researchers mainly explore the benefits of digitalization. Using cases in three companies, this paper explores the practices, challenges, and opportunities faced by Thailand food manufacturers in digitalizing their food supply chains. A framework for food supply chain digitalization is proposed and its implications for research and practices are discussed. 相似文献

Combining Food Frequency and Survey Data to Quantify Long-Term Dietary Exposure: A Methyl Mercury Case Study 总被引:2,自引:0,他引:2
Twenty-four-hour recall data from the Continuing Survey of Food Intake by Individuals (CSFII) are frequently used to estimate dietary exposure for risk assessment. Food frequency questionnaires are traditional instruments of epidemiological research; however, their application in dietary exposure and risk assessment has been limited. This article presents a probabilistic method of bridging the National Health and Nutrition Examination Survey (NHANES) food frequency and the CSFII data to estimate longitudinal (usual) intake, using a case study of seafood mercury exposures for two population subgroups (females 16 to 49 years and children 1 to 5 years). Two hundred forty-nine CSFII food codes were mapped into 28 NHANES fish/shellfish categories. FDA and state/local seafood mercury data were used. A uniform distribution with minimum and maximum blood-diet ratios of 0.66 to 1.07 was assumed. A probabilistic assessment was conducted to estimate distributions of individual 30-day average daily fish/shellfish intakes, methyl mercury exposure, and blood levels. The upper percentile estimates of fish and shellfish intakes based on the 30-day daily averages were lower than those based on two- and three-day daily averages. These results support previous findings that distributions of "usual" intakes based on a small number of consumption days provide overestimates in the upper percentiles. About 10% of the females (16 to 49 years) and children (1 to 5 years) may be exposed to mercury levels above the EPA's RfD. The predicted 75th and 90th percentile blood mercury levels for the females in the 16-to-49-year group were similar to those reported by NHANES. The predicted 90th percentile blood mercury levels for children in the 1-to-5-year subgroup was similar to NHANES and the 75th percentile estimates were slightly above the NHANES. 相似文献

To serve Korean American families effectively, marriage and family therapists need to develop a level of cultural competence. This content analysis of the relevant treatment literature was conducted to discover the most common expert recommendations for family therapy with Asian Americans and to examine their application to Korean Americans. Eleven specific guidelines were generated: Assess support systems, assess immigration history establish professional credibility, provide role induction, facilitate "saving face," accept somatic complaints, be present/problem focused, be directive, respect family structure, be nonconfrontational, and provide positive reframes. Empirical support (clinical and nonclinical research) and conceptual support for each guideline are discussed, and conclusions are reached regarding culturally competent therapy with Korean American families. 相似文献

Best practice in couple relationship education 总被引:1,自引:1,他引:0
Relationship education is widely available to couples and is intended to reduce the prevalence of relationship distress, divorce, and the associated personal and social costs. To realize the potential benefits of couple relationship education, it needs to be evidence-based, offered in ways that attract couples at high-risk for relationship problems, and focused on factors that put couples at high-risk for future relationship problems. 相似文献

Heavy episodic drinking and college entrance 总被引:1,自引:0,他引:1
The college environment appears to encourage heavy drinking. Consequently, correlates of student drinking were assessed at college entrance. First-semester freshmen (N = 520, 54 percent women) completed self-report measures of social affiliation and self/peer drinking for high school and college. Analyses indicated that: 1) increased drinking at college entrance mirrored perceived increases by peers, 2) perceptions of peer drinking were robustly overestimated with women displaying the larger overestimation bias; and 3) social affiliation was associated with men's drinking and moderated its relation to perceived peer drinking at college entrance. These results advance understanding of the manner in which heavy drinking patterns emerge as men and women enter college, and campus programs that consider these factors may better promote health and reduce the harms associated with heavy drinking among college students. 相似文献
