葛逻禄是由三个部落组成的联盟,唐代时分属唐朝4个都督府管辖。从766年起葛逻禄成为伊斯兰世界的紧邻,并在中亚形成一种势力。840年蒙古高原的回纥汗国灭亡,回纥散往四方,其一支逃往葛逻禄避难。喀喇汗王朝是葛逻禄统治者接受了回纥汗国阿史那汗族(或“阿夫拉西亚勃家族”的一支)归这一家族所有的可汗职位。在伊斯兰历史著作中有三条关于萨曼王朝的伊斯玛因于893年对西部喀喇汗国战争的报道,它们可以相互补充。此外,这三个报道中还有关于喀喇汗王朝与葛逻禄为同一部族的重要情报。 相似文献

现代逻辑的价值和意义,在于其在理论上的应用。对于纯数学的基础和结构来说,现代逻辑是一种非常有用的工具,包括哥德尔不完全性定理等,都利用了现代逻辑的技术和成果。某些现代逻辑技术已经广泛应用到了工程学之中,例如,计算机工程就基于现代逻辑的高级成果。反过来,这些应用又刺激了逻辑理论本身取得更多的进步。 相似文献

The use of thimerosal preservative in childhood vaccines has been largely eliminated over the past decade in the United States because vaccines have been reformulated in single‐dose vials that do not require preservative. An exception is the inactivated influenza vaccines, which are formulated in both multidose vials requiring preservative and preservative‐free single‐dose vials. As part of an ongoing evaluation by USFDA of the safety of biologics throughout their lifecycle, the infant body burden of mercury following scheduled exposures to thimerosal preservative in inactivated influenza vaccines in the United States was estimated and compared to the infant body burden of mercury following daily exposures to dietary methylmercury at the reference dose established by the USEPA. Body burdens were estimated using kinetic parameters derived from experiments conducted in infant monkeys that were exposed episodically to thimerosal or MeHg at identical doses. We found that the body burden of mercury (AUC) in infants (including low birth weight) over the first 4.5 years of life following yearly exposures to thimerosal was two orders of magnitude lower than that estimated for exposures to the lowest regulatory threshold for MeHg over the same time period. In addition, peak body burdens of mercury following episodic exposures to thimerosal in this worst‐case analysis did not exceed the corresponding safe body burden of mercury from methylmercury at any time, even for low‐birth‐weight infants. Our pharmacokinetic analysis supports the acknowledged safety of thimerosal when used as a preservative at current levels in certain multidose infant vaccines in the United States. 相似文献

ABSTRACTThis paper explores the challenges of outsidership faced by multinational companies (MNCs) accessing emerging economies. The paper departs from popular conceptualisations of culture drawing instead on social identity theory as part of an institutions-based view, to explain how employing a singularities approach can allow the identification of commonalities of Indianness and Australianness that can be leveraged to ameliorate negative socially embedded business norms that pose a challenge to MNC success in emerging economies. This study shows that despite recognised formal (regulatory) and informal (cultural) differences, managers of Australian MNCs operating in India were able to innovatively identify and exploit cultural commonalties/singularities to ease cultural adjustment and mitigate intergroup conflict, allowing them to achieve an innovative institutional fit. The paper discusses how, using this approach, sole-venture MNCs can access many of the benefits provided by collaborative entry modes while preserving MNC identity. We further propose that the singularities approach can provide a valuable starting point to develop culturally appropriate competence training initiatives. 相似文献

Provisions of the Adoption and Safe Families Act of 1997 mandated shorter time frames for making permanency decisions and facilitating adoption. Yet for many children, foster care continued to be a significant portion of their life experiences. This project explored the potential permanency option of birthfamilies and extended kin for children who languished in foster care while being free for adoption. Eighteen children achieved permanent placement with their birthfamilies. In addition, staff found that although many families could not provide permanent placements, they could offer appropriate relationships with the children. This project team recommends viewing family relationships as an integral component where placement is one option on a continuum that includes letters, phone calls, and visits. 相似文献

There is a need to investigate novel interventions that promote worksite physical activity and wellness. OBJECTIVE: The authors' purpose in this study was to evaluate the effectiveness of a 12-week walking program supplemented with a pedometer, computer educational program, and weekly e-mails. METHODS: College faculty and staff participated in a one-group pre-posttest study to determine whether the 12-week walking intervention had an effect on body mass index (BMI), blood pressure, blood glucose, and cholesterol. The authors also determined participant-perceived wellness effects. RESULTS: The authors observed differences between baseline and follow-up in BMI (p = .024), blood glucose (p = .06), and total cholesterol (p = .09). The program had a moderate effect on fitness, mood, health awareness, nutrition, and health. CONCLUSIONS: It is incumbent that experts develop innovative worksite physical activity and wellness programs. A pedometer-monitored walking program is one way that a worksite health initiative can improve the health and wellness of its employees and simultaneously reduce health-care costs. 相似文献

The role of voluntary and community sector organizations in the delivery of public services is increasing and these changes
bring new responsibilities and benefits to organizations that have the capacity to participate. There are concerns within
the sector about the implications for citizenship and participation. The sector is highly dependent on volunteers yet little
is known about how organizational change in response to new relationships with the statutory sector impact upon the commitment
and well-being of people who volunteer. This paper addresses that gap in knowledge for older volunteers. Drawing upon collaborative
research with a voluntary organization in the north of England, the authors explore the meanings and aspirations of volunteering
for older people, and explain how and why changes associated with closer engagement with public service delivery and less
grant dependency can be disempowering for them.

Relocation stress syndrome is a nursing diagnosis characterized by symptoms such as anxiety, confusion, hopelessness, and loneliness. It usually occurs in older adults shortly after moving from a private residence to a nursing home or assisted-living facility. The primary purpose of this study was to validate the symptoms of relocation stress syndrome. Eight nursing home residents and 8 assisted-living facility residents were interviewed 2 to 10 weeks after admission, when symptoms of relocation stress syndrome are most likely to appear. Results of this study indicate that the incidence of relocation stress syndrome may be overestimated. More accurate diagnosis and treatment of depression in older adults is needed. 相似文献
