Using the General Social Survey from 1972–2014, we examine variation in attitudes toward retaining controversial materials in libraries. Previously controversial topics have become much more widely accepted. We find that other controversies remain, showing how global conflicts become intertwined in local cultural controversies, and how the perceived threat from particular groups informs public concern with disseminating information from those groups. We find that more frequent library users are somewhat less likely to want to remove controversial books from the shelves, although some of these relationships are explained by variation in the respondent’s age, race, and other characteristics. 相似文献

Cost effective, quantifiable assessment of lower extremity movement represents potential improvement over standard tools for evaluation of injury risk. Ten healthy participants completed three trials of a drop jump, overhead squat, and single leg squat task. Peak hip and knee kinematics were assessed using an 8 camera BTS Smart 7000DX motion analysis system and the Microsoft Kinect® camera system. The agreement and consistency between both uncorrected and correct Kinect kinematic variables and the BTS camera system were assessed using interclass correlations coefficients. Peak sagittal plane kinematics measured using the Microsoft Kinect® camera system explained a significant amount of variance [Rangehip = 43.5–62.8%; Rangeknee = 67.5–89.6%] in peak kinematics measured using the BTS camera system. Across tasks, peak knee flexion angle and peak hip flexion were found to be consistent and in agreement when the Microsoft Kinect® camera system was directly compared to the BTS camera system but these values were improved following application of a corrective factor. The Microsoft Kinect® may not be an appropriate surrogate for traditional motion analysis technology, but it may have potential applications as a real-time feedback tool in pathological or high injury risk populations. 相似文献

The aims of this study were to describe normative values and seasonal variation of body composition in female cyclists comparing female road and track endurance cyclists, and to validate the use of anthropometry to monitor lean mass changes. Anthropometric profiles (seven site skinfolds) were measured over 16 years from 126 female cyclists. Lean mass index (LMI) was calculated as body weight?×?skinfolds?x. The exponent (x) was calculated as the slope of the natural logarithm of body weight and skinfolds. Percentage changes in LMI were compared to lean mass changes measured using dual-energy X-ray absorptiometry (DXA) in a subset of 25 road cyclists. Compared to sub-elite and elite cyclists, world class cyclists were (mean [95% CI]) 1.18?kg [0.46, 1.90] and 0.60?kg [0.05, 1.15] lighter and had skinfolds that were 7.4?mm [3.8, 11.0] and 4.6?mm [1.8, 7.4] lower, respectively. Body weight (0.41?kg [0.04, 0.77]) and skinfolds (4.0?mm [2.1, 6.0]) were higher in the off-season compared to the early-season. World class female road cyclists had lower body weight (6.04?kg [2.73, 9.35]) and skinfolds (11.5?mm [1.1, 21.9]) than track endurance cyclists. LMI (mean exponent 0.15 [0.13, 0.18]) explained 87% of the variance in DXA lean mass. In conclusion, higher performing female cyclists were lighter and leaner than their less successful peers, road cyclists were lighter and leaner than track endurance cyclists, and weight and skinfolds were lowest early in the season. LMI appears to be a reasonably valid tool for monitoring lean mass changes. 相似文献

We present a curriculum that prepares students for supporting large Enterprise Information Systems (EIS). EIS is best explained
through the evolution of Enterprise Resource Planning (ERP). These systems evolved over the last years driven by (1) changing
business requirements and (2) new development capabilities provided by technologies evolution and software vendors’ innovation.
These developments led to a new discipline—Enterprise Information Systems, which deals with issues whose focus is on creating
and sustaining business benefits through the utilization of corporate IT infrastructure assets. Currently, EIS knowledge is
essentially acquired on the job after substantial time of experience building and longer career ladder scale. This paper presents
an experience of a curriculum implementation that prepares students for the pervasive EIS landscape in meeting today’s corporate
needs. Our IT-based educational approach is evaluated as an alternative to prevailing Business-based approaches to EIS instruction.
In this IT-rooted approach, the curriculum is divided into four sections: a Core IT block of courses followed by two progressive-levels
of advanced EIS-related specialized subjects, and an industry-oriented field-training experience. Initially, a Core IT background
provides a foundation for IT innovation in developing EIS components at sophomore-level. A junior-level of specialized instruction
introduces integrated modules which form EIS platforms. Finally, supporting technologies of EIS-related processes and workflows
are presented at senior-level of specialized EIS instruction. An assessment case study of the proposed Enterprise System programs
is carried out through which we discuss the results of the curriculum performance. 相似文献

In this article, I explore the dynamic relationship between political and organizational change in higher education. Change is interrogated in relation to policies and discourses of New Right reform, mass expansion, new managerialism, equity and post‐modernist theories of power, with questions raised about the interconnection of demographic changes, consumer entitlement and equality of opportunity. I consider the extent to which economic, intellectual and socio‐cultural changes intersect. Equity is examined in relation to the democratic rhetoric of enhanced access and connections are made between equality and quality by questioning the changing nature of the product being accessed by new student populations. 相似文献

Lamaze Certified Childbirth Educators have a duty to their clients to make referrals to qualified professionals-in this case, to an expert in nutrition, a dietician. A reasonable way to assure a quality referral is to contact the appropriate professional organization. 相似文献

Unwillingness to share depression experiences with primary care physicians contributes to the undertreatment of depression. This project examined college students’ reasons for depression nondisclosure to primary care providers (PCPs). Undergraduate participants read a vignette describing someone with depression and completed measures of disclosure barriers. Analyses indicated 26% of respondents would NOT disclose depression symptoms to PCPs. Reasons for nondisclosure included difficulty initiating the depression conversation, medication aversion, and fear of referral to a psychologist. Also, anger toward the vignette character varied with disclosure willingness, suggesting that nondisclosers feel more stigma than disclosers and are less likely to engage in psychotherapy. Because engagement in pharmacological and/or psychotherapeutic treatment requires identification of depression in healthcare settings, increased understanding of disclosure barriers could increase students’ access to depression treatment. 相似文献
