This article identifies similarities and differences between Head Start parents of European American and Puerto Rican backgrounds regarding their socialization goals and expectations concerning the early educational experiences of their pre‐school children. Semi‐structured interviews were conducted with 60 parents (30 European American and 30 Puerto Rican) in their homes. The results show that both groups of parents valued pro‐social skills, school readiness skills, and skills related to good behaviour. Both sets of parents considered creative and physical skills to be least important. However, differences between groups were found regarding the relative importance of skills in the different developmental domains. The findings suggest that to maximize the effects of early childhood programmes and interventions it is important that educators and policy makers recognize and respond to differences in parents’ goals and expectations. 相似文献

This study examined the relationship of research library visions, as embodied in a publicly posted vision statement, and the innovativeness of the library. The literature on organizational vision is abundant and generally reveals a positive relationship between vision, visionary leadership, and a variety of organizational factors. Many researchers state that a vision, communicated throughout the organization, is a critical element of organizational success and those entities without a vision are “stumbling in the dark”. In this study, library professionals rated each research library vision statement based on established attributes and it was found that the resulting vision statement score was positively and significantly related to the innovativeness of the library. 相似文献

The results are presented of a policy-focused review of career guidance services in 10 Middle East and North African countries.
A range of economic, political, socio-cultural and educational factors which seem likely to have constrained the development
of such services, and to have influenced the forms they have taken, are discussed. A number of drivers for change are outlined,
the nature of the main current services is described, and a number of common issues are explored. Six broad themes are identified
for the future development of career guidance services within the region. 相似文献

The problem of observing the state of a linear finite dimensional system in the presence of unknown disturbance noise is considered. Necessary and sufficient conditions are developed for the existence of a minimal order observer capable of producing an asymptotic estimate of the state of the given system. The approach used leads to a computationally attractive procedure for obtaining an observer having specified eigenvalues. 相似文献

Systemic and paradigmatic problems inherent in science instruction are a genuine threat to our health, and that of future generations. By examining the discoveries of two unsung heroes of 20th century medical science, and the poor acceptance of their dietary interventions in disease processes, we have sufficient evidence to incite a careful re-evaluation and alteration of the methods with which we teach science, and, in fact, all subject areas in our schools and postsecondary institutions. F.C. Dohan and W. Dicke each discovered answers to pathologies through dietary exclusion of gluten. Neither has enjoyed the just fruits of their labours. 相似文献

A model is presented regarding associations between economic strain, support from spouse, and quality of parenting. The model was tested using a sample of 451 2-parent families, each of which included a seventh grader (age 12-13). Parent and adolescent reports, as well as observational ratings, were used as indicators of constructs. Analysis using structural equation modeling procedures indicated that level of spouse support was positively related to supportive parenting, whereas economic strain operated to undermine parental involvement. As posited, economic strain produced its effect through a direct relation with parenting and indirectly through its association with spouse support. These findings held for mothers and fathers, regardless of the gender of the child. Spouse support moderated the impact of economic strain on supportive parenting for mothers but not fathers. Possible explanations for this gender difference are presented. 相似文献

Predicting university preference and attendance: Applied marketing in higher education administration 总被引:2,自引:0,他引:2
A multi-attribute attitude model, based on the efforts of Rosenberg and Fishbein, was used to determine whether a multicriteria scale can be used to predict student preferences for and attendance at universities. Data were gathered from 241 freshmen attending five state universities in Ohio. Responsents were asked to weight the importance of 18 selection criteria and evaluate seven universities using those criteria. These data were processed through the model, and the results were compared to the respondents' preference ordering of the universities. The results indicate a high level of predictability, particularly for highly ranked universities. Implications for the marketing of higher educational institutions are discussed. 相似文献

This study examined point‐in‐time and point‐of‐view antecedent cue effects on teachers’ and mental health workers’ perceptions of life events’ impact on students. Increased congruence between student and adult perceptions of life events’ impact was demonstrated via systematic variation of cue conditions designed to limit the contribution of historical and personal referents. Implications are discussed in terms of future research and training efforts. 相似文献
