This study focused on an examination of the work of 10 diversity committees operating in 10 research institutions across the midwestern region of the United States. We explored the work of these committees with a focus on the concept of strategic diversity leadership. To conduct this examination we examined five contingencies impacting the work of the committees: a clear definition of diversity, the scope of operation, the importance of committee membership, the role and responsibilities of the committee, and the permanence of the group. Based upon our findings we offer recommendations for diversity committees to contribute to institutional efforts focused on diversity. 相似文献

Optimal exercise performance in well trained athletes can be affected by arterial oxygen saturation failure. Noninvasive detection of this phenomenon when performing a routine ergometric test can be a valuable tool for subsequent planning of the athlete's training, recovery, and nutrition. Oximetry has been used to this end. The authors studied 339 athletes performing a similar exercise trial under well controlled environmental conditions. Maximum speed, oxygen uptake, and heart rate levels were simultaneously measured. From the obtained data, six patterns were found: (a) athletes in whom oxygen saturation is constant (≥ 95%) during test execution; (b) athletes displaying a progressive desaturation with incremental exercise intensities; (c) athletes presenting a transient desaturation in the anaerobic threshold region; (d) athletes starting with a mild-to-moderate desaturation at the beginning of the test, but reaching normal saturation values at the end; (e) athletes displaying mild-to-moderate desaturation levels throughout the whole test; and (f) athletes displaying a transient desaturation in the anaerobic threshold region and a new desaturation at the end of the test. In conclusion, it is believed that establishment of desaturation patterns by validated oximetry could be a first approach to evaluate the adaptation of the cardiorespiratory system to exercise intensity, helping to improve results. 相似文献

Children's ability to monitor subjective feelings of uncertainty (i.e., engage in uncertainty monitoring) is a central metacognitive skill. In the current study, we examined the development of uncertainty monitoring as well as its relations with vocabulary and executive function development in children (N = 137, 52% female) from predominately White and Latinx/Hispanic backgrounds when they were 4–6 years old and enrolled in a Head Start preschool and kindergarten between 2018 and 2019. We found that children's uncertainty monitoring improved during the kindergarten year. Children's executive function and vocabulary in preschool and vocabulary growth from preschool to kindergarten predicted uncertainty monitoring at the end of kindergarten, which sheds new light on potential mechanisms supporting children's metacognitive development. 相似文献

ABSTRACTWe examined the association between footfall pattern and characteristics of lower limb muscle function and compared lower limb muscle function between forefoot and rearfoot runners. Fifteen rearfoot and 16 forefoot runners were evaluated using ultrasonography of the gastrocnemii and tibialis anterior while strike index and heel strike angle quantified footfall pattern. Higher strike index was associated with lower medial gastrocnemius echo intensity (p = 0.05), lower lateral gastrocnemius echo intensity (p = 0.04), smaller tibialis anterior pennation angle (p = 0.05), and longer lateral gastrocnemius fascicle length (p = 0.04). Larger heel strike angle was associated with smaller medial gastrocnemius cross-sectional area (p = 0.04), shorter lateral gastrocnemius fascicle length (p < 0.01), and lower plantar flexion moment (p < 0.01). Larger plantar flexion moment was associated with lesser medial gastrocnemius echo intensity (p = 0.04), lesser lateral gastrocnemius echo intensity (p = 0.03), and greater lateral gastrocnemius fascicle length (p = 0.02). A smaller plantar flexion moment, larger heel strike angle, lower tibialis anterior echo intensity, larger tibialis anterior pennation angle, and smaller lateral gastrocnemius pennation angle were observed in rearfoot compared to forefoot runners (p < 0.05). Lower limb muscle architecture is associated with footfall pattern and ankle mechanics during running.Abbreviation: EMG: electromyographic; MG: medial gastrocnemius; LG: lateral gastrocnemius; TA: tibialis anterior; EI: echo intensity; CSA: cross-sectional area; PA: pennation angle; FL: fascicle length; FT: fat thickness 相似文献

The influence of the physical structure of polyurethane matrix as a support in a solid state culture in tannase production
and gallic acid accumulation by Aspergillus niger Aa-20 was evaluated. Three different polyurethane matrices were used as the support: continuous, semi-discontinuous and discontinuous.
The highest tannase production at 2479.59 U/L during the first 12 h of culture was obtained using the discontinuous matrix.
The gallic acid was accumulated at 7.64 g/L at the discontinuous matrix. The results show that the discontinuous matrix of
polyurethane is better for tannase production and gallic acid accumulation in a solid state culture bioprocess than the continuous
and semi-discontinuous matrices.

The rising number of data portals has been increasing demand for new techniques to assess data openness in an automated manner. Some methods have emerged that presuppose well-organized data catalogs, the availability of API interfaces and natively exposed metadata. However, many data portals, particularly those of local governments, appear to be misimplemented and developed with the classic website model in mind, which provides access to data only through user interaction with web forms. Data in such portals resides in the hidden part of the web, as it is dynamically produced only in response to direct requests. This paper proposes an automated method for assessing government-related data in the deep web on the basis of compliance with open data principles and requirements. To validate our method, we apply it in an experiment using the government websites of the 27 Brazilian capitals. The method is fully carried out for 22 of the capitals' websites, resulting in the analysis of 5.6 million government web pages. The results indicate that the keyword search approach utilized in the method, along with the checking of web pages for multifield web forms, is effective for identifying deep web data sources, as 1.5% of web pages with potential government data that are analyzed are found to contain data stored in the deep web. This work contributes to the development of a novel method that allows for the continuous checking and identification of government data from surface web data portals. In addition, this method can be scaled and repeated to assure the widest possible content coverage. 相似文献

The rapid changes in technology used in the library and cultural heritage sectors can make it difficult for early career librarians and LIS students interested in library technology positions to know what skills will be most beneficial to their job search. In this study, 492 librarian and archivist job postings from the Code4Libs Jobs website from between 2008 and 2018 were collected and analyzed to find which programming technologies are most in demand overall and which are most requested for specific types of jobs and specific types of employers, including changes over time. The results provide a glimpse of programming languages and technologies that are widely useful in the field of library technology today, as well as those that are growing in use. 相似文献

This article reports the results and conclusions of a mixed-methods research strategy designed to assess the potential of community networking in rural Tamil Nadu, India. The data reported and analyzed in this article include socioeconomic and household spending, agricultural marketing and price search, availability and use of information on agricultural problems, and communication media use. We use these data to define a framework of existing sources of information for various community agents, with a special emphasis on farmers. We analyze the methods and costs at which these agents obtain information, and identify information and communication gaps that information and communication technologies (ICTs) may help alleviate. This study allows us to demonstrate opportunities for socioeconomic development through ICT-enabled information access. The article concludes by stating the importance of basic communication technologies and contextually relevant information services, and suggesting recommendations for future research in this area. 相似文献

Neither Too Sweet nor Too Sour: Problem Peers, Maternal Control, and Problem Behavior in African American Adolescents 总被引：5，自引：0，他引：5
This study examined whether maternal control protects African American adolescents from the negative influence of problem peers. Two forms of control were examined, behavioral control and psychological control. It was hypothesized that there would be a curvilinear relation between control and adolescent problem behavior, with the strength of the relationship and the amount of control optimal for adolescent development varying by the level of peer problem behavior. In general, data supported this model, particularly in regard to behavioral control, where the predicted curvilinear interaction occurred even after controlling for initial levels of problem behavior. The predicted curvilinear interaction between psychological control and peer problem behavior was statistically significant if initial levels of problem behavior were not controlled for but was not significant after controlling for initial problem behavior. These findings suggest that high-quality parenting can play a modest but critical role in the face of environmental adversity. 相似文献
