The research goal was to study the law faculty's interlibrary loan and OhioLINK borrowing activity to assess current subject gaps in the Cleveland-Marshall College of Law Library's collection. The authors analyzed and collated faculty research interests. The results indicate that additional purchases are required to support international law and health law, two curriculum areas currently under development at Cleveland-Marshall. 相似文献

Academic interlibrary loan practitioners are experiencing changes that can be characterized as either the fragmentation of the resource sharing mission or its evolution into a new form of service routinely making use of new and diverse sources of information outside the scope of past practices. Among these new sources are curated repositories of open access literature, institutional repositories, digital libraries containing scanned public domain literature, and social media article-sharing networking sites. The incorporation of these sources of information into regular workflows presents interlibrary loan practitioners with many challenges. This paper will discuss ways to address these developments. 相似文献

In the open marketplace of visuals where the most valued photographs “rise to the top” via tweets, likes, and retweets rather than being dictated by professionals, the study of what makes an image go really social is merited. One occurrence during which professional photojournalism and nonprofessional photography truly coexist, intermingle, and blur is that of a natural disaster. A body of research exists that has examined the visual framing of disasters, but none has addressed how these differently framed photos go social online or by whom. In this study, 1,078 Twitter photos shared by professional media outlets and nonprofessional tweeters were examined to see what portrayals of photos are elevated in the network. Established frames and new frames were examined: depictions of people, emotional hierarchy, novelty, victims, ordinary people, uniforms, emergency professionals, valence, pragmatic, human interest, and political. The results add empirical evidence to the different ways that professional members of media and other visual sharers understand, visually communicate, and react to disaster and add to the visual framing literature an element of really social visual framing. 相似文献

Social networking sites are considered a valuable resource to maintain existing friendships even over considerable distances. The present study emphasizes tie strength as a crucial determinant for the use of interactive and passive features among 302 active Facebook users and friends of different relational closeness (close friends vs. casual friends vs. acquaintances) as well as a moderator for the impact of physical distance. As expected, tie strength affected direct interaction linearly, whereas social surveillance followed a quadratic trend. Furthermore, moderation analyses revealed less frequent direct interaction between close friends and stronger surveillance of casual friends’ profiles as physical distance increases. These results indicate different functions in relationship maintenance for both behaviors as direct interaction aims at nurturing current relationships, while surveillance serves as a catalyst for promising future communications. As a consequence, physical distance influences direct interaction adversely due to emerging constraints but also contains informational value encouraging information-seeking behaviors. 相似文献

Objective
The research obtained information to plan data-related products and services.Methods
Biomedical researchers in an academic medical center were selected using purposive sampling and interviewed using open-ended questions based on a literature review. Interviews were conducted until saturation was achieved.Results
Interview responses informed library planners about researchers’ key data issues.Conclusions
This approach proved valuable for planning data management products and services and raising library visibility among clients in the research data realm. 相似文献159.

Lower limb dominance (or lateral preference) could potentially effect functional performance. Clinicians are often asked to make judgements as to when a patient has sufficiently “recovered” from an injury, typically using strength and dynamic performance outcome measures. The primary purpose of this study was to systematically review the literature in relation to limb dominance within active adult populations and discuss some limitations to current methods and relate this to current clinical practice. A search of MEDLINE and CINAHL and EMBASE databases and reference lists of those articles identified was performed. Eleven articles were selected for meta-analysis. There was no statistical effect of limb dominance for any of the functional tests: isokinetic quadriceps and hamstring tests, hamstring:quadriceps ratios, single-leg hop for distance, single-leg vertical jump and vertical ground reaction force following a single-leg vertical jump. Pooled symmetry values varied from 94.6% to 99.6% across the tests, above the clinically accepted benchmark of 90% used in clinical practice. Although the results of this study must be used with discretion, asymmetries in the tasks described in this analysis should be viewed as undesirable and remedied accordingly. Further research is needed to quantify asymmetries, particularly in relation to sport-specific contexts. 相似文献

The study examined how preschool intervention programmes set up by three Scottish local authorities changed parents’ cognitions. Quantitative parent outcomes were measured using Parenting Daily Hassles Scales (N = 88). A matched comparison group of parents (N = 55) recruited from the same areas of disadvantage but whose children did not attend the intervention programmes also completed questionnaires. Qualitative outcomes were evaluated using semi‐structured interviews (N = 30). A significant group × time interaction effect was found for daily hassle cognitions, Parenting Task–Intensity, Challenging Behaviour–Frequency and Challenging Behaviour–Intensity, with comparison group parents showing an increase in their experience of hassles during the ‘terrible twos’ compared with intervention group parents. Complementary qualitative data indicated that intervention group parents had gained valuable new insights into their children’s behaviour, changing how they thought about their role as parents and their behavioural and developmental expectations of their children. Implications for parental engagement in preschool programmes are discussed. 相似文献
