Public librarians are not always able or willing to embrace their role as providers of social and institutional capital for homeless patrons. Yet their position as gatekeepers impels them to do so. Through focus-group interviews with staff of homeless shelters in eight urban communities in one Midwestern state, this study explored the collaboration and communication between homeless shelters and public libraries. Findings indicate that homeless shelter staff recognize the value of public library services for their residents but do not engage in coordinated efforts to capitalize on it. Suggestions for enhanced collaboration between the two institutions are included. 相似文献

Pavlov (1927/1960) reported that following the conditioning of several stimuli, extinction of one conditioned stimulus (CS) attenuated responding
to others that had not undergone direct extinction. However, this secondary extinction effect has not been widely replicated in the contemporary literature. In three conditioned suppression experiments with rats,
we further explored the phenomenon. In Experiment 1, we asked whether secondary extinction is more likely to occur with target
CSs that have themselves undergone some prior extinction. A robust secondary extinction effect was obtained with a nonextinguished
target CS. Experiment 2 showed that extinction of one CS was sufficient to reduce renewal of a second CS when it was tested
in a neutral (nonextinction) context. In Experiment 3, secondary extinction was observed in groups that initially received
intermixed conditioning trials with the target and nontarget CSs, but not in groups that received conditioning of the two
CSs in separate sessions. The results are consistent with the hypothesis that CSs must be associated with a common temporal
context during conditioning for secondary extinction to occur. 相似文献

As hypermedia, online teacher professional development (TPD) should ideally support diverse learners to work with online content
effectively because it involves multiple representations and a nonlinear format. Differences among participants in motivation
and learning provide challenges for design. The present study is a use-inspired, mixed-method study of 164 teachers’ motivation
and learning in an unmoderated online workshop. It addresses participants’ demographic and motivational profiles, participation
in this type of workshop (e.g., the frequency, duration, and focus, as well as their work with technology-enhanced, nonroutine
challenge problems and journal assignments), the predictive value of the initial questionnaire, and implications for design.
Findings indicate that while three clusters of motivational profiles could be identified (low interest, low self-efficacy,
and less math; low interest, high self-efficacy, and more math; high interest, high self-efficacy, and more math), whether
the teachers continue to participate appears to be related to the structure and content of the workshop, not just these profiles.
Findings are interpreted as suggesting that the potential of hypermedia lies in its designers’ abilities to support participant
stake by providing for multiple ways into thinking and working with disciplinary content—design that both accommodates and
supports those with differing strengths and needs. Implications for studying motivation and learning online are also discussed. 相似文献

There is currently much debate about the safety of the sport of softball. Batted‐ball speed and average pitcher reaction time are factors often used to determine safe performance. Batted‐ball speed is shown to be the most important factor to consider when determining safe play. Average pitcher reaction time is explained and directly correlated to batted‐ball speed. Eleven aluminum multi‐wall, three aluminum single‐wall and two composite softball bats were tested with mid‐compression polyurethane softballs averaging 1721 ±62 N/6.4 mm to represent the relative bat‐ball performance for the sport of slow‐pitch softball. Nine men and six women were chosen for this study out of a test group of over three hundred slowpitch softball players. On average, aluminum bat performance results were within the recommended safety limits established by the national softball associations. However, when composite bats were used, their performance results exceeded the recommended safety limits which can pose a significant safety risk. Using aluminum softball bats, batted‐ball speeds ranged from 80 to 145 km.h‐1. Using composite softball bats, batted‐ball speeds ranged from 146 to 161 km.h‐1. The scientific relevance of this study is to provide performance information that can lead to injury prevention in the sport of softball. 相似文献

The purpose of this study was to analyze the introduction of the performance-based pay system (PPS) in Korean national universities through the perspective of institutional isomorphism. Using three isomorphism concepts of coercive, mimetic, and normative, and further framing the PPS within the overarching theoretical frameworks of governmentality, neoliberalism, myth, and policy convergence, this study explored the historical and social background of the PPS, the reason the Korean government pursued the PPS form used in the US higher education, and the main factors that affected its introduction in Korean national universities. The result of this analysis shows that while the institutionalization of the PPS in Korean national universities seemed closely associated with the radical political, economic change in Korean society, it was in fact an exemplar of isomorphism from the US model of public and private higher education. This isomorphic activity functioned simultaneously as a norm, social order, and myth within Korean higher education while faculty displayed an anti-isomorphic tendency against the power of the institutional isomorphism of PPS in national universities. 相似文献

The altruistic act of body donation provides a precious resource for both teaching and researching human anatomy. However, relatively little is known about individuals who donate their bodies to science (donors), and in particular whether donors in different geographical locations share similar characteristics. A multicenter prospective survey of donors registering during 2010 in three different geographical locations, New Zealand, Ireland, and the Republic of South Africa, was conducted to identify donor characteristics. The 28-question survey included sections on body donation program awareness, reasons for donating, giving tendency, education, ethnicity, relationship status, occupation, religion, and political preference. Two hundred surveys (81%) were returned [New Zealand 123 (85% response rate), Republic of South Africa 41 (67%), and Ireland 36 (92%)]. Results indicate that donors share certain characteristics including reason for donating (80% cited a desire to aid medical science as the main reason for wishing to donate their body); family structure (most donors are or have been in long-term partnerships and ≥ 85% have siblings); and a higher proportion with no religious affiliation compared to their reference population. Some variations between locations were noted including donor age, the mode of program awareness, occupation, relationship status, political preference, organ donor status and with whom donors had discussed their decision to donate. This information could be important for assisting the identification of potential body donors in new and established bequest programs. 相似文献

This study examines the relationships between the normative and resource dimensions of a high school counseling department and four-year college-going rates. Utilizing data from the High School Longitudinal Study of 2009 (HSLS: 09), we employ multiple regression and latent class analysis to identify salient factors related to the college-going culture of a high school and to classify schools according to their underlying counseling opportunity structure, respectively. Results demonstrate that both norms (i.e., average caseload and hours spent on college counseling) and resources (i.e., college fairs, college course offerings, and financial aid) are important predictors of a school’s four-year college-going rates. These results, in turn, produced a three-level typology of schools based on a divergent, emergent, and convergent classification system. The study concludes with a discussion of findings and implications for researchers and policymakers interested in improving and better understanding the counseling opportunity structure. 相似文献

To what needs and purposes should the primary curriculum be chiefly directed in the coming decades? In a first step towards revising the primary curriculum, the National Council for Curriculum and Assessment (NCCA) invited responses to an open online call to ‘have your say’ on priorities for primary education. Respondents were asked to share their views in 100 words or less. Six priorities for primary education were identified across the 960 responses. These focused on developing children's life-skills; communication skills; well-being; literacy and numeracy skills; motivation and engagement; and their sense of identity and belonging. Across the priorities, there is recognition that skills learned in the primary years are related to one another and the extent to which children develop these is likely to have wide-ranging effects on their future experience as learners. Findings call for a revision of traditional, content-based curriculum subjects towards a better alignment with the needs of today's primary school children beginning with a more explicit focus on life-skills, and children's social and emotional development. Finally, we note the common ground across early childhood, primary and post-primary sectors and highlight the potential to align our values and vision for children and young people's education from the earliest years through adulthood. 相似文献
