Techniques for Tracking Perpetual Access     

Chris Bulock 《期刊图书馆员》2015,68(1-4):290-298

Tracking perpetual access entitlements is a challenging task that is too often simply ignored. Here, the presenter makes the case for the importance of systematically tracking perpetual access and outlines the information that is necessary to record. The presenter also draws on the literature and conversations with ten librarians working on the issue to provide a set of techniques for this task. These techniques incorporate several different systems common to academic libraries and include scenarios that illustrate the use in common situations.  相似文献   

The effect of breast support and breast pain on upper-extremity kinematics during running: implications for females with large breasts     

Jennifer White  Chris Mills  Nick Ball  Joanna Scurr 《Journal of sports sciences》2015,33(19):2043-2050

The relationship between inappropriate breast support and upper-extremity kinematics for female runners is unclear. The purpose of this study was to investigate the effect of breast support and breast pain on upper-extremity kinematics during running. Eleven female recreational runners with larger breasts (UK D and E cup) completed a 7 min 20 s treadmill run (2.58 m · s^?1) in a high and low breast support condition. Multi-planar breast and upper-extremity kinematic data were captured in each breast support condition by eight infrared cameras for 30 s towards the end of the run. Breast pain was rated at the end of each treadmill run using a numeric analogue scale. The high support bra reduced breast kinematics and decreased breast pain (P < 0.05). Upper-extremity kinematics did not differ between breast support conditions (P > 0.05), although some moderate positive correlations were found between thorax range of motion and breast kinematics (r = 0.54 to 0.73). Thorax and arm kinematics do not appear to be influenced by breast support level in female runners with large breasts. A high support bra that offers good multi-planar breast support is recommended for female runners with larger breasts to reduce breast pain.  相似文献   

The movement of the trunk and breast during front crawl and breaststroke swimming     

Chris Mills  Mitch Lomax  Bessie Ayres  Joanna Scurr 《Journal of sports sciences》2015,33(4):427-436

Breast displacement has been investigated in various activities to inform bra design, with the goal of minimising movement; however, breast motion during swimming has yet to be considered. The aim was to investigate trunk and breast kinematics whilst wearing varying levels of breast support during two swimming strokes. Six larger-breasted females swam front crawl and breaststroke (in a swimming flume), in three breast support conditions while three video cameras recorded the motion of the trunk and right breast. Trunk and relative breast kinematics were calculated. Greater breast displacement occurred mediolaterally in the swimsuit condition (7.8, s = 1.5 cm) during front crawl and superioinferiorly in the bare-breasted condition (3.7, s = 1.6 cm) during breaststroke, with the sports bra significantly reducing breast displacements. During front crawl, the greatest trunk roll occurred in the sports bra condition (43.1, s = 8.3°) and during breaststroke greater trunk extension occurred in the swimsuit condition (55.4, s = 5.0°); however, no differences were found in trunk kinematics between the three breast support conditions. Results suggest that the swimsuit was ineffective as a means of additional support for larger-breasted women during swimming; incorporating design features of sports bras into swimsuits may improve the breast support provided.  相似文献   

Reinforcing attitudes in a gatewatching news era: Individual-level antecedents to sharing fact-checks on social media     

Michelle A. Amazeen  Chris J. Vargo  Toby Hopp 《Communication monographs》2019,86(1):112-132

Despite the prevalence of fact-checking, little is known about who posts fact-checks online. Based upon a content analysis of Facebook and Twitter digital trace data and a linked online survey (N?=?783), this study reveals that sharing fact-checks in political conversations on social media is linked to age, ideology, and political behaviors. Moreover, an individual’s need for orientation (NFO) is an even stronger predictor of sharing a fact-check than ideological intensity or relevance, alone, and also influences the type of fact-check format (with or without a rating scale) that is shared. Finally, participants generally shared fact-checks to reinforce their existing attitudes. Consequently, concerns over the effects of fact-checking should move beyond a limited-effects approach (e.g., changing attitudes) to also include reinforcing accurate beliefs.  相似文献   

Social capital in the classroom: a study of in-class social capital and school adjustment     

Ronan Van Rossem  Marjolijn Vermande  Beate Völker  Chris Baerveldt 《British Journal of Sociology of Education》2015,36(5):669-688

Social capital is generally considered beneficial for students’ school adjustment. This paper argues that social relationships among pupils generate social capital at both the individual and the class levels, and that each has its unique effect on pupils’ performance and well-being. The sample in this study consists of 1036 children in 60 first-grade classes in 46 Dutch elementary schools. Multilevel regression results show that a substantial proportion of the variance in school adjustment can be attributed to the class level and that both individual-level and classroom-level social capital have substantial effects on school adjustment. At the individual level, the size of one’s network is more important than its structure. At the collective level, social capital also has a ‘dark side’ because it can have negative effects on adjustment, lowering the academic performance in a class.  相似文献   

Building Inclusive Pedagogy: Recommendations From a National Study of Students of Color in Higher Education and Student Affairs Graduate Programs     

Chris Linder  Jessica C. Harris  Evette L. Allen  Bryan Hubain 《Equity & Excellence in Education》2015,48(2):178-194

In this study, we share the racialized experiences of 29 students of color in higher education and student affairs graduate programs, focusing specifically on their relationships with faculty, their experiences in classrooms, and the strategies they recommend for inclusion. Participants indicated that they are expected to serve as the racial expert in classrooms and that many faculty fail to effectively facilitate discussions related to race and racism and to intervene in instances of racial microaggressions. Participants convey effective strategies to build racially-inclusive classrooms which include authenticity, vulnerability, and validation.  相似文献   

Benefits for immigrant-origin and nonimmigrant-origin youth of discussing immigration in gender and sexuality alliances     

Sarah B. Rosenbach  S. Henry Sherwood  V. Paul Poteat  Hirokazu Yoshikawa  Jerel P. Calzo 《Psychology in the schools》2022,59(1):152-180

In a time of unprecedented polarization in the United States, particularly concerning immigration, schools are uniquely positioned to help students understand the consequences of drastic policy changes. Beyond formal settings such as social studies classes, extracurricular activities may be important for fostering discussions about sociohistorical and policy issues. Such discussions could serve to empower youth from marginalized populations and raise their critical consciousness. Yet the potential outcomes of discussions in these extracurricular settings have not been studied in depth. Using data collected in school-based Gender-and-Sexuality-Alliances (GSAs) throughout Massachusetts during the periods leading up to and following the 2016 US Presidential election, we examined whether discussions of immigration issues in GSAs were associated with greater empowerment and critical consciousness among 580 youth (M _Age = 15.59, range = 10–20 years). Multilevel structural equation models showed that the frequency with which youth discussed immigration, relative to their fellow members, was positively associated with residualized change in perceived peer validation for members in general and with residualized change in hope for immigrant-origin members only. Contrary to our expectations, we did not find significant associations for critical consciousness. Findings suggest how groups addressing issues of equity and justice can promote members' empowerment.  相似文献   

In search of systemic innovation for sustainable development: A design praxis emerging from a decade of social learning inquiry

Processes of designing for systemic innovation for sustainable development (SD) through the lens of three long-term case studies are reported. All case studies, which originated from the SLIM (Social Learning for the Integrated Management and Sustainable Use of Water at Catchment Scale) Project, funded within the EU Fifth Framework Program (2001–2004), constitute inquiry pathways that are explored using a critical incident approach. The initial starting conditions for each inquiry pathway are compared; significant pathway dependencies are identified which foster the development of social learning processes locally, but constrain their uptake and embedding across the wider system of interest. In the first case study, in England & Wales, promising developments in the application of social learning approaches to river basin planning over an initial 3-year period were subsequently marginalised, only to resurface towards the end of the 10-year period of study. In the second, South African case study, significant spaces for social learning and innovation in integrated water resources management were opened up over a five year period but closed down again, primarily as the result of lack of policy support by national government. The third, Italian, case study was designed to assess options for adapting to climate change by opening up new learning spaces between researchers, stakeholders and policy makers. A case for investing in local level systemic innovation through social-learning praxis design approaches and in learning processes around well contextualised case-studies is supported. However, concomitant investment by policy makers in social learning as an alternative, but complementary, governance mechanism for systemic innovation for SD is needed.  相似文献   

Quantum phenomena in Communities of Practice     

Richard Ribeiro  Chris Kimble  Paul Cairns 《International Journal of Information Management》2010

Although Communities of Practice have become a core concept in understanding how knowledge is managed within organizations, there have been few studies of the praxis of formation of Communities of Practice. In this article, we report on a Grounded Theory study of the members of a previously identified Community of Practice within the UK Higher Education Academy Psychology Network. In addition to providing data on the functioning of the community, the study also revealed a hitherto unrecognized form of community that exhibits all of the characteristics of CoPs yet has only a transient existence that seems to nucleate around an existing core community. Drawing on the metaphor of quantum behaviour, we termed these communities Quantum Communities of Practice. We describe a theory to explain this phenomenon that is grounded in the data from the study. We conclude by discussing the value and validity of our findings and methodology and indicating the next steps we will take in our research.  相似文献
