期刊文献分布特征的分析

以1999-2003年生物技术学科期刊文献分布曲线为依据,利用知识密度梯度graduR(n)的概念,对知识场中文献分布特征进行分析。结果表明,在任何一个学科的知识场中,集中区文献分布呈间断性变化,离散区文献分布呈连续性变化,从而构成期刊文献分布的基本特征。基于此,指出期刊文献分布特征研究是对文献分布规律的进一步描述。

First-rib stress fracture in two adolescent swimmers: a case report

First-rib stress fractures have been described in adolescent athletes in various sports, with only one prior case report of first-rib stress fractures in an adolescent female swimmer. There is a need for research on the cause, management, and prevention of these injuries as they lead to significant morbidity and critical time away from sport for these aspiring athletes. We aimed to describe first-rib stress fractures as a potential cause for non-specific atraumatic chronic shoulder pain in adolescent swimmers and to discuss the different presentations, unique risk factors, treatment, and potential injury prevention strategies of such fractures. We discussed two such cases which were successfully treated with activity modification with restriction of all overhead activity, gradually progressive physical therapy and a return to swimming protocol. First-rib stress fractures can vary in presentation and should be in the differential diagnosis in adolescent swimmers with chronic shoulder pain. These injuries can be successfully managed with rest from overhead activities and physical therapy. Gradual return to competitive swimming can be achieved even with non-union of a first-rib stress fracture. Emphasis on balanced strength training in different muscle groups and proper swimming technique is essential to prevent these injuries.

Diversity in the Information Seeking Behaviour of the Virtual Scholar: Institutional Comparisons

The logs of four universities using the OhioLINK journal system were evaluated for a period of fifteen months using deep log analysis methods in order to compare and contrast the information seeking behaviour of their users. Large differences were found, especially between the research and teaching universities. Methodological problems associated with making the comparisons are discussed in some detail especially in terms of defining online sessions.
