Naturalizing Korean ethnicity and making ‘ethnic’ difference: a comparison of North Korean settlement and foreign bride incorporation policies in South Korea

This article compares North Korean immigrants and foreign bride policies in South Korea. Despite being constructed as distinctive policy target groups, North Korean settlement and foreign bride incorporation policies exhibit striking similarities. The similarities result from the way policy problems are identified and certain solutions are justified; both North Korean immigrants and foreign brides are constructed a burden on welfare and as potential threats to social stability. Policy solutions are justified as they are designed to transform North Korean immigrants and foreign brides into ‘normal’ South Korean citizens. The major difference between two sets of policies lies in assumptions regarding cultural differences. Foreign brides are assumed to carry practices that are foreign and alien to Koreans, while North Korean immigrants are presumed to carry ‘authentic’ and ‘traditional’ Korean culture. Foreign brides’ cultures are visible and alien to South Koreans, and therefore are addressed under the banner of multiculturalism policies. North Korean immigrants are excluded from such policies. This exclusion reflects and reproduces the view of a Korean nation bounded by ethnic and cultural homogeneity.     

Health status and behaviors of unwed fathers

This article focuses on the well-being and capacities of 1759 new fathers in seven cities using data from the Fragile Families Study. Comparisons are made between married (N=478) and unmarried fathers (N=1281). With the unwed fathers, we compare those who are cohabiting, who are stably romantically involved but not cohabiting, who are involved in an unstable romantic relationship, who are not romantically involved but friends, and who have no relationship with the mother. The six indicators of fathers' well-being capacities include physical health, depressive symptoms, drug and alcohol use, smoking, and physical abuse of the mother. These findings show that married fathers are more advantaged than unwed fathers vis-à-vis education, income, and age; they also are in better physical and mental health. Among the unwed fathers, those who are cohabiting are more advantaged and healthier than those who are not cohabiting, although the differences are not as great as those between married and unmarried fathers. Non-resident fathers who are romantically involved are similar in income, age and education to fathers who are not romantically involved but are friends, although the former are less likely than the latter to be using drugs, to be depressed or to have hit or slapped the mother. The fathers who are romantically involved in an unstable (i.e., off-and-on) relationship are less healthy than those in a more sustained romantic or cohabiting relationship. The fathers who have no relationship with the mother are most likely to exhibit unhealthy behaviors. About two percent of the married fathers, 3% of the unmarried cohabiting and stably romantically involved, 5% of the unstably romantically involved, 7% of the friends, and 11% of those with no relationship had hit or slapped the mother as reported by her. About one-half of the married fathers, a little over a third of the unwed fathers who are cohabiting, stably romantically involved or unstably romantically involved or friends, and only one-sixth of the fathers with no relationship have none of the six behaviors. In contrast, one-fifth of the unwed fathers with no relationship and one-eighth of the unstably romantically involved fathers have three or more of the six risky behaviors, as compared to one-tenth of the unwed fathers with involvement and 3% of the married fathers. Implications for welfare reform and child support are discussed.     

Metaphysics and professional resistance to program evaluation

One of the most common and most difficult problems confronting program evaluators is the resistance they encounter when attempting to implement evaluation efforts. The philosophical and psychological foundations of this resistance are explored. Problems in the evaluative paradigm are presented. Value differences between evaluators and practitioners are highlighted. Emotional bases for practitioner behavior are clarified and types and loci of resistance are outlined. Suggestions for coping strategies are discussed.     

Paternal involvement among unwed fathers

Paternal involvement among unwed fathers is examined during pregnancy and at birth. The effects of relationship status, race and ethnicity, age, education, income, family structure and father values on father involvement are also examined. The findings suggest that overall there is a high degree of involvement among all the fathers examined. Relationship status is statistically significant and most predictive in assessing paternal involvement in each analysis. Fathers who are romantically involved and cohabiting are more involved than those who are romantically involved but do not cohabit. Fathers who are no longer romantically involved are least likely to sustain involvement. In addition, fathers who are employed are also more likely to sustain involvement.     

Job Loss and the Occupational Social Worker

Economic and technological changes are creating workplace and labor market upheavals. While new jobs are being rapidly created, many old ones are destroyed. Some new jobs are high-paying, but many are low-paying with little opportunity for advancement. Especially affected are higher-paid blue-collar workers and middle managers, often ill-equipped to cope with jobchange. The authors discuss the impact of job-loss and downsizing on individuals and organizations, and describe current dislocated worker and outplacement services. Occupational social work skills are seen as particularly appropriate for lay-off interventions.     

COMPLIMENTS WILL GET YOU NOWHERE:

Benign stereotypes of Jews are widespread, but whether they are genuinely complimentary remains unresolved. This study addresses the question using data from the 1990 General Social Survey. There are four main findings. First, benign Jewish stereotypes are far more common than corresponding blatantly anti-Semitic images. Second, there is no evidence that benign stereotypes are genuinely complimentary but strong indications that they are subtle expressions of underlying prejudice. Third, many non-Jews simultaneously both benign stereotypes and blatantly anti-Semitic stereotypes. Fourth, unlike blatant expressions of prejudice, benign stereotypes are more common among the well educated and affluent. Implications are drawn concerning the nature, extent, and future of anti-Semitic prejudice.     

Chinese Children's Changing Family and School Environments

As a result of modernization, major changes are taking place in children's social relationships. Children are beginning to view their parents more as friends and colleagues rather than powerful authority figures. Parents are realizing that their children face a new, uncharted future and are more inclined to consider their children's point of view. The generation gap is viewed as evidence of social progress. Children and parents are growing into the future together. Increased pressure from economic development results in increasing demands on the educational system. Private schools, some of which are very costly, are on the rise. The entire educational system, including laws governing schools, student-teacher relations, and expectations about goals for educational quality are being revised.     

The Influence of the Socio-economic Characteristics of Disabled People on Their Employment Status and Income

Most of the studies of the employment and income levels of disabled people focus on a specific disability or on severely disabled persons. A few studies are cross disability ones, but they fail to go beyond simple associations or else have extremely small sample sizes. There is a need for studies which are cross disability and which have an adequate sample size in order to determine if there are structural variables in society—like a class system-which operate upon the employment opportunities of disabled persons. Using a sample (n = 733) of the Disability Community in Massachusetts, socio-economic variables related to employment and income are studied. Statistically significant relationships are found. Several models are developed and the implications for social theory are discussed.     

The Social Worker's Role in Serving Vulnerable Athletes

Athletes are a population group with unique vulnerabilities whose social work-related needs are often not met. Because of the perception that they are young and healthy, athletes are seen as free from mental health challenges and social problems. Yet athletes are at high risk for distress due to pressures to perform, avoid showing pain, hide physical injuries and substance abuse problems, eating disorders and burnout. At the same time, they may have false support systems that are interested in the athlete for social or monetary status. Social workers are broad systems practitioners who can focus on how the environment and other influences affect an athlete's mental health and well-being. Because social workers are strengths-based, they can assist athletes in achieving their highest level of functioning on and off the playing field.     

Design for worksystem safety using employees' perception about safety

In this paper, the predictors of work injuries based on Leamon's Man-Machine model are identified in a sociotechnical framework. Several hypotheses are developed and tested to describe the accident/injury phenomena in mining worksystems. Possible designs for improving work-system's safety are specified using scaled Mahalanobis distance (MD). A case control study design is adopted. Five variables namely, age, negative-affectivity, physical-hazards, job-dissatisfaction, and safety-practice are emerged as significant contributors to work injuries for the mines studied. Two most interesting findings obtained through this study are (i) 36% of cases (injured employees) (MD < 1) are unlucky to meet an accident and (ii) 40% of the controls (non-injured employees) (MD > 1) are lucky to be able to avoid an accident. The most probable reason for the former case is the organizational ineffectiveness while that for the latter may be risky adventures of employees which are due to lack of education, awareness, and appropriate training. Based on the MD values for cases and controls, possible design guidelines are suggested. The study categorically identifies the accident situations where engineering control, education and training, and other organizational safety measures are to be adopted.
