Using a framework based on social cognitive career theory, we conducted 38 interviews and four focus groups with college students to identify motivations and barriers faced by underrepresented groups to natural resource careers. Interviews revealed career satisfaction as the most important goal for both natural resource and a comparison of liberal arts students. School difficulty and outsider perceptions were barriers for both groups. Natural resource students faced family pressure to pursue other careers. Focus groups with natural resource students using Q methodology revealed participation in outdoor recreation, exposure to nature-related media, and witnessing environmental degradation as important influences. Barriers included perceptions of ethnic/racial discrimination, financial pressures, and lack of confidence. Results may help academia and agencies better address motivations and barriers to natural resource careers.  相似文献

This article provides a cross‐national perspective on successful school principalship in three countries derived from an analysis of case studies in the International Successful School Principalship Project (ISSPP). The ISSPP aims to investigate the characteristics, processes and effects of successful school leadership across eight countries (i.e. Australia, Canada, England, the United States, China, Denmark, Sweden and Norway). Examples from the USA, Norway and China (Shanghai) were selected to illustrate cross‐national differences related to the societal purposes of education, the structure and funding of different national educational systems and the influence of particular governmental educational policies (i.e. accountability‐oriented policies) on the leadership practices of individual school principals. Variations in selection criteria and research procedures were also noted. Recommendations for further research using a cultural framework include analysing multiethnic schools to identify culturally specific leadership practices as well as developing further ISSPP case studies in non‐Western contexts.  相似文献

Summary Responses were obtained from 50 fourth and ninth grade teachers on a 55-item test of their attitudes toward television in the classroom after 33 of them had been involved and 17 not involved in television series which introduced new ways of teaching mathematics. Intercorrelations were computed, and factors were analyzed. The resulting factor structure indicated 10 unique factors of the attitudes expressed. No general factor was found. The ten factors were tentatively identified as follows: challenge-threat, economy, instructional side-benefits, partnership between TV and classroom teachers, responsiveness, parental influences, security of the classroom teacher, invidious comparison, experimental attitude, and in-service training. On the whole the teachers’ attitudes were highly favorable to instructional television, and consistently rejected the idea that the TV teacher represents a threat to the classroom teacher.  相似文献

We present 14 design observations for public safety networks (PSNs) and describe how they may apply more broadly to a wider range of inter-organizational systems within the public sector. A PSN is an interagency collaboration focused on developing and using information systems in support of information sharing and functional interoperability among public safety organizations engaged in law enforcement, criminal justice, and emergency response. We base our design observations upon an analysis of an extensive survey of 80 PSNs plus 6 in-depth case studies. The design observations identify commonalities that can guide agencies participating in interagency collaborations in addressing the interlocking issues they face. Our goal in presenting this set of design observations is to: (1) encourage improved PSN systems design and (2) draw attention to the importance of jointly addressing governance and technological considerations when designing PSNs.  相似文献

Collection assessment is a key component of collection development, budget allocation, and justification of library collections. Unfortunately, comprehensive collection assessment is daunting, subject to the weaknesses of individual tools and the overwhelming number of subject areas to assess. Few studies have attempted systematic assessment projects using multiple tools or methods, nor have many attempted to assess an entire collection subject-by-subject. This study implements an alternative to the single-tool model, combining multi-tool analysis with a systematic, subject-by-subject approach to the collection. The goal was to determine whether such a model of collection assessment was feasible in an academic library setting, providing usable data without overinvestment of manpower and resources. To this end, the method was tested in a pilot program at George Mason University (Mason), assessing three subjects at varying levels of depth. While there was concern that the methodology would prove too ambitious for full-scale implementation, the pilot yielded valuable, tangible results in a timely manner and provides a solid model for future assessment efforts at Mason and elsewhere.  相似文献

This study examined the association of gestational diabetes mellitus (GDM), prenatal, and postnatal maternal depressive symptoms with externalizing, internalizing, and autism spectrum problems on the Preschool Child Behavior Checklist in 2379 children aged 4.12 ± 0.60 (48% female; 47% White, 32% Black, 15% Mixed Race, 4% Asian, <2% American Indian/Alaskan Native, <2% Native Hawaiian; 23% Hispanic). Data were collected from the NIH Environmental influences on Child Health Outcomes (ECHO) Program from 2009-2021. GDM, prenatal, and postnatal maternal depressive symptoms were each associated with increased child externalizing and internalizing problems. GDM was associated with increased autism behaviors only among children exposed to perinatal maternal depressive symptoms above the median level. Stratified analyses revealed a relation between GDM and child outcomes in males only.  相似文献
