Cooperative Remote Storage: Challenges for Resource Sharing

Cooperative storage involves two or more libraries sharing space within a facility. Kansas State University leases space at the Library Annex, a remote storage facility owned and operated by the University of Kansas. Various challenges are involved in maintaining access to remotely stored materials for resource sharing and document delivery purposes. The authors, staff members of the Interlibrary Services Unit at Kansas State University, discuss variables affecting access to remote materials and share their experience working within a cooperative storage model.     

Play and Problem‐solving in a New Light

This article presents a model of children's play, explored from an evolutionary perspective. Surprisingly, an evolutionary approach has only recently been introduced into this field, especially as far as learning is concerned, and is virtually unknown in educational studies. However, such an approach seems entirely reasonable if one accepts that cognitive activities are a product of evolution and selection. Moreover, there is some urgency in stressing the contribution biological sciences can make to the study of children's early development, since there exists an enormous amount of research of immediate relevance to educators that has apparently been ignored.     

The Impact of Sustained, Standards-Based Professional Learning on Second and Third Grade Teachers’ Content and Pedagogical Knowledge in Integrated Mathematics

This 3 year longitudinal study reports the feasibility of an Improving Teacher Quality: No Child Left Behind project for impacting teachers’ content and pedagogical knowledge in mathematics in nine Title I elementary schools in the southeastern United States. Data were collected for 3 years to determine the impact of standards and research-based teacher training on these aspects of teacher quality. Content knowledge for the scope of this research study refers to the knowledge that teachers have about subject matter. Teacher quality is directly related to teachers’ “highly qualified” status, as defined by the No Child Left Behind mandate. According to this mandate, every classroom should have a teacher qualified to teach in his subject area and be able to “raise the percentage of students who are proficient in reading and math, and in narrowing the test-score gap between advantaged and disadvantaged students.” Participants were six second grade and seven third grade teachers of mathematics from nine schools within one failing school district. The implementation of standards-based methods in the nine Title I Schools increased teacher quality in elementary school mathematics. In fact, qualitative and quantitative data revealed significant gains in teachers’ mathematics content and pedagogical knowledge at both grade levels.     

The effects of protease supplementation on skeletal muscle function and DOMS following downhill running

Protease supplementation has been shown to attenuate soft tissue injury resulting from intense exercise. The aim of this study was to evaluate the effects of protease supplementation on muscle soreness and contractile performance after downhill running. Ten matched pairs of male participants ran at a -10% grade for 30 min at 80% of their predicted maximal heart rate. The participants consumed two protease tablets (325 mg pancreatic enzymes, 75 mg trypsin, 50 mg papain, 50 mg bromelain, 10 mg amylase, 10 mg lipase, 10 mg lysozyme, 2 mg chymotrypisn) or a placebo four times a day beginning 1 day before exercise and lasting a total of 4 days. The participants were evaluated for perceived muscle soreness of the front and back of the dominant leg, pressure pain threshold by dolorimetry of the anterior medial, anterior lateral, posterior medial and posterior lateral quadrants of the thigh, and knee extension/flexion torque and power. The experimental group demonstrated superior recovery of contractile function and diminished effects of delayed-onset muscle soreness after downhill running when compared with the placebo group. Our results indicate that protease supplementation may attenuate muscle soreness after downhill running. Protease supplementation may also facilitate muscle healing and allow for faster restoration of contractile function after intense exercise.
