P J Pecora 《Child welfare》1989,68(4):403-419
Competency-based needs assessment surveys can be useful in assessing worker training needs in child welfare. Worker and supervisor surveys, consisting largely of task-based ability statements, constitute the core of this approach. Additional information can also be obtained from supervisors and allied professionals. Data from a study of 276 frontline child welfare workers in Alaska and Oregon are used to illustrate the utility of this approach.  相似文献

A questionnaire was designed to determine the type of drug education program most desired by undergraduate students attending a major university. The survey was to provide the basis for a comprehensive drug education program. The 101 item questionnaire elicited responses from 656 undergraduates in categories ranging from knowledge base to credible information sources. The analysis of student desires as they relate to program design is included in this article. The students strongly believed the university should provide a drug education program. In particular they desired a credit course dealing with both drugs and alcohol. They also wanted regularly published articles on drugs in school publications. The most credible knowledge sources were PhDs and MDs. Students also wanted contact with former drug users. More than half the students believed that values clarification and "coping skills" training would decrease their drug use. In general more women than men were likely to utilize such resources.  相似文献

This paper postulates that there is a continuous exchange of information and knowledge between those who share the common bond of having migrated to the US. The individual components of this information exchange constitute social networks. The 2 hypotheses tested are 1) immediate social networks and people known in the US facilitate the flow of information both to new migrants and between established migrants, thus promoting upward social mobility; and 2) access to broader network ties, organization membership, extra-ethnic friendships, and familiarity with established institutions smooths the transition process, resulting in increased social position. The data used comes from a study conducted in 1982-1983 in 4 Mexican sending communities (2 rural, 2 urban), for a total of 440 migrants. Results show that migrants in every socioeconomic bracket reported access to some or all social network characteristics. There was contact with either a family member or acquaintances from the migrants' town of origin. Over 50% of migrants reported knowing many fellow townspeople. Twice as many migrants belong to a sports club as to a social or religious organization. Very few rural migrants report knowing no townspeople, while 32% of urban migrants claim no knowledge of fellow migrants from their town of origin. Urban origin migrants report more contacts with those of other ethnicity than rural migrants. Those employed in agriculture are least acquainted with social information and contacts, while those in skilled and service sectors are well acquainted with them. The results of fact and analysis show that 1) access to personal US networks results in an average 4.4 point advantage in occupational prestige scores over no access, and 2) utilizing institutional US networks combined with any cumulative US experience gives a migrant a 5 point advantage over a fellow migrant with identical experience level but no institutional network contacts. This is also true for institutional Mexican networks. Thus success or failure in migrating is partly due to migrants' societal infrastructure and the fact that available information and social networks are accessed and utilized differently by different migrants.  相似文献

Population-to-practitioner ratios have long been the primary index in the designation of health manpower shortage areas. This paper documents that application of the widely used population-to-dentist index results in understatement of the need for dental health manpower in rural areas. Through the analysis of utilization data collected from a statewide health screening program in Colorado, the practice of sole reliance on the population-to-dentist indices as an indicator of need was tested. Another measure, the area-(square miles) to-dentist ratio was formulated, examined, and found to be a more useful referent of the need for additional health manpower in rural areas. Utilization of dental services in sparsely settled rural counties of Colorado was unrelated to population-to-dentist ratios. A strong, statistically significant association of utilization with land area-to-dentist ratios was found. The findings of this analysis suggest a need for reevaluation of needs assessment methodologies used in the designation of health manpower shortage areas. Indices more sensitive to consumer circumstance than to the number of health care providers available must be considered.  相似文献

Self-control training with maltreating parents   总被引:1,自引:0,他引:1  
Seeking a method of intervention based on research about correlates of child maltreatment, the authors find that small-group, short-term training in self-control and child management skills gives parents the tools to better handle family stress and develop supportive social networks.  相似文献

This paper reports an exploration of the structure of consumer confidence in four of the countries participating in the EEC harmonized consumer attitudes surveys. The analysis is based on two EEC surveys in each of the countries concerned and uses the rotated solutions on the first three factors of the data. It was found that the different countries and surveys had similar factor structures which were interpreted as general economic conditions: personal financial circumstances; household durable buying intentions. The position of price expectations and attitudes to saving within these factor structures is also of interest in the interpretation of consumer behaviour.  相似文献

Using a sociodemographic model of the determinants of illegitimacy rates, a multivariate regression analysis of annual change in age-specific Swedish illegitimacy rates is applied to the 1911-74 period. The proxy measure of change in sexual activity was significant for all age groups. Legitimation rates for out-of-wedlock conceived births were significant for all ages except teenagers, and the final predictor, women's status, was significant for all ages except women 35-44. Explained variance for annual change was highest among ages 20-24 (66%), 25-29 (66%), and 30-34 (63%) and lower among teens (34%) and women 35-44 (47%). These results support earlier research that used a sociodemographic model to explain post-World War II change in cross-national illegitimacy rates among 23 developed countries.  相似文献
