Background: Somali Bantu refugees, with unique health information needs, created challenges for health and social service providers. Objectives: A service innovation was developed (i) to raise awareness, especially among local health and social service providers, about the Bantu refugees’ presence in the community, their culture, and their information needs and (ii) to deliver needed health information, emphasizing child health, to the Bantu mothers in their homes. Methods: The project consisted of: (i) a community conference targeting local health and social service providers, describing the refugees’ presence in the community, their culture, and information needs. (ii) Focus groups conducted with members of the Bantu population elicited additional information needs. (iii) Curriculum was developed based on identified needs, and (iv) the curriculum was delivered to the refugees in their homes. A clinical informationist and MP3 technology enhanced the project. Findings: Conference attendees’ evaluation responses indicated improved understanding of Bantu culture. Focus groups’ identification of health information needs provided a framework for the health education curriculum. A project website made educational materials available to other healthcare providers. Conclusions: The project raised awareness of the Bantus’ presence, culture, and information needs. Identification of other unmet needs demonstrated that additional support for refugees is required. 相似文献

Employee book clubs are simple, inexpensive tools for professional development that may be more effective than traditional training methods. Library staff at Brigham Young University participated in professional development book clubs, and they reported that they found these trainings to be more enjoyable than classroom-style trainings and more effective in helping them understand, retain, and apply the principles learned. This article will discuss the success of these book clubs and suggest ways that other libraries can implement cost-effective book clubs to develop professional and leadership skills. 相似文献

ABSTRACTThe development of non-Orthodox Jewish day schools in Los Angeles in the 1970s to 1990s can be attributed to a combination of factors, including the city’s geography, the deterioration of public education, court-ordered busing that began in the 1970s, and strong rabbinic personalities. Yet, as elementary day schools proliferated throughout the city, educators struggled to keep secondary day schools afloat. Contributing factors to the challenges secondary schools faced included sprawling city geography, lack of communal support, and parental desire to send children to established high schools with proven track records for college preparation and admission. 相似文献

ABSTRACT Preservation of cuneiform tablets made with clay minerals is an ongoing conservation issue. A treatment based on TEOS consolidation has been used since 1996 at the Louvre museum. The characterization of the tablets pointed out kaolinite, illite, and smectite as the three main clay minerals constituting the objects. In this research, the physico-mechanical aspects of the treatment are investigated. The penetration depth of the TEOS solution and the gradient induced are quantified using laboratory samples. TEOS treatment preserves the macroscopic swelling and the vapour transfer properties, but modifies the clay’s affinity to moisture. Elastic properties are gradually improved for all clays, but only kaolinite’s strength increases significantly. The impact of TEOS treatment on the natural behaviour related to the respective structure of the clays is considered, and the amount of kaolinite required to create adequate reactions appears to be of interest for conservation treatments. 相似文献

ABSTRACT This paper examines how organisations have increasingly been portrayed in textbooks as solving social problems as well as contributing to national development. Findings from 527 Canadian and U.S. textbooks illustrate the rise of an organisational society during the time period between 1836 and 2011. Discussions of for-profit and non-profit forms of organisations rise early on in both countries, creating the foundation for an organisational society, which expands to incorporate global organisations in the post-World War II period. We argue that such portrayals in textbooks both reflect and legitimise the role of organisations in society, strengthening their taken-for-granted status as social actors. 相似文献

ABSTRACT This study aimed to systematically review the association between cardiorespiratory fitness and telomere length (TL). Studies were identified from searches in Cochrane Central, PubMed, Scopus, Sportdiscus, and Web of Science databases through July 2019. Eligibility criteria included: cross-sectional, prospective, and experimental study design; outcomes included TL; results expressed the relationship between cardiorespiratory fitness and TL; studies published in English, Portuguese, or Spanish. A total of 20 articles met the inclusion criteria. Sixteen studies (80%) reported a significant relationship between cardiorespiratory fitness, or training load, and TL. Better cardiorespiratory fitness or a large cardiorespiratory training load are associated with an increase in TL. Although, TL was related to regular moderate-to-vigorous aerobic exercise and cardiorespiratory fitness in older healthy humans, it was not related to cardiorespiratory fitness among young subjects. There seems to be a positive and significant relationship between cardiorespiratory fitness and TL, mainly among middle age and older people, which emphasizes the importance of cardiorespiratory fitness for healthy ageing. Therefore, endurance exercise and better cardiorespiratory fitness may regulate the TL in middle age and older adults, slowing the cellular ageing process. 相似文献

Co‐teaching in a mainstream post‐primary mathematics classroom: an evaluation of models of co‐teaching from the perspective of the teachers 下载免费PDF全文
This article examines the use of a range of co‐teaching models when teaching mathematics. The approaches suggested have potential for all students, but in this instance their importance as a pedagogical approach with students with special educational needs (SEN) in inclusive classrooms is considered. The study was based in the first‐year mathematics classroom of an Irish, urban, mainstream, post‐primary, girls’ school. This article highlights the findings from the teacher's perspective and presents their reflections on a range of co‐teaching approaches. The potential and challenges of these are considered in the context of schools generally. 相似文献
