Cognitive Interviewing: A Qualitative Tool for Improving Questionnaires in Sport Science

This study sought to determine whether body fat percentage estimates using an inexpensive bioelectrical impedance analysis (BIA) device (Tanita TBF-521, Tanita Corp, of America, Arlington Heights, IL) could be freely substituted for those obtained utilizing skinfolds (method equivalence). Data were analyzed from measurements on 38 children age 6 to 12 years. Random effect intraclass correlation (r = .930; 95% confidence interval [CI] = .87 to .96), fixed effect intraclass correlation (r = .932; 95% CI = .87 to .96), and least-products regression supported the equivalence of the 2 methods. The technical error between the 2 methods (3.7; coefficient of variation = 12.2%) was small and also supported the equivalence of the two methods. The ability of the BIA device to categorize into normal and obese categories when compared to the skinfold technique was also impressive (κ = .95; 95% CI = .73 to .99). However, the results of the limits of agreement analysis showed that the approximate 95% CI for the differences between methods was wide (-9.1 to 11.4).     

Statistical relationships between corresponding authorship,international co-authorship and citation impact of national research systems

This paper presents a statistical analysis of the relationship between three science indicators applied in earlier bibliometric studies, namely research leadership based on corresponding authorship, international collaboration using international co-authorship data, and field-normalized citation impact. Indicators at the level of countries are extracted from the SIR database created by SCImago Research Group from publication records indexed for Elsevier’s Scopus. The relationship between authorship and citation-based indicators is found to be complex, as it reflects a country’s phase of scientific development and the coverage policy of the database. Moreover, one should distinguish a genuine leadership effect from a purely statistical effect due to fractional counting. Further analyses at the level of institutions and qualitative validation studies are recommended.     

Globetrotting Students and Faculty: Adapting Library Instruction to Global Sites

ABSTRACT

As e-resources become more ubiquitous, and the technologies available to access them more sophisticated, libraries have greater opportunities to reach out to global users. However, this same distance means that some users never even set foot in a physical library. This case study will describe how one large academic library started a business, economics, and marketing library online instruction pilot for global users in an effort to replicate library instruction offered at the home institution. Librarians assessed global library use and research needs; prepared unique lesson plans for each global site; and created digital learning objects using synchronous and asynchronous methods to establish an instruction strategy for Business and Economics courses. The goal was to test instruction practices and develop an online instruction template that would be replicable and sustainable for library instruction in other subject areas in New York University Libraries and other institutions.     

Providing ability to probability: Reducing cognitive load through worked‐out examples

Undergraduate students tend to struggle with probability in their introductory statistics course. Probability problem solving requires several steps. First, students must make sense of the probability scenario, then determine the appropriate probability rules, and finally, execute the procedures to solve the problem. With no previous exposure to probability, this presents too great a cognitive load for many students. Using worked‐out problems then transitioning to partially worked‐out problems in an introductory statistics course at a large university helped students succeed at solving probability problems. The worked‐out problems included writing prompts to encourage self‐explanation of students' thinking through studying the worked‐out examples. This paper explains the use of these instructional principles and their implementation in an introductory statistics course for non‐STEM majors, resulting in higher student achievement and understanding.     

Power Analysis for Complex Mediational Designs Using Monte Carlo Methods

Applied researchers often include mediation effects in applications of advanced methods such as latent variable models and linear growth curve models. Guidance on how to estimate statistical power to detect mediation for these models has not yet been addressed in the literature. We describe a general framework for power analyses for complex mediational models. The approach is based on the well-known technique of generating a large number of samples in a Monte Carlo study, and estimating power as the percentage of cases in which an estimate of interest is significantly different from zero. Examples of power calculation for commonly used mediational models are provided. Power analyses for the single mediator, multiple mediators, 3-path mediation, mediation with latent variables, moderated mediation, and mediation in longitudinal designs are described. Annotated sample syntax for Mplus is appended and tabled values of required sample sizes are shown for some models.

Integrating educational institutions to produce intellectual capital for sustainability in Caguas,Puerto Rico

This research is part of a broader investigation to analyse the processes followed by the Caguas Municipality at the Commonwealth of Puerto Rico in an effort to develop the characteristics of a ‘Smart City’ as an example of sustainable development. We describe the integration of the educational institutions’ initiatives and the municipal government strategic plan to contribute to the knowledge and intellectual capital that brings sustainability to the city. An actor's model was designed to represent this integration. The conceptual framework was based on the concepts of knowledge production and sharing as applied to the collaboration between critical representative actors. Field research consisting of in-depth interviews was performed to ascertain the integration processes and their relationship with such processes of knowledge production and sharing. The results showed that the governance paradigm implemented is already empowering the citizens to contribute with intellectual capital that brings sustainability to Caguas.     

THE UNIVERSITY OF THE PEOPLES OF EUROPE: WHAT IT COULD BE

Inspired by the coining together of the various countries of Europe, by the rebirth, at all levels, of interest in the common European identity, and by the growing European consensus as to the importance of the university as a major pan‐European cultural institution, the author, First Deputy Chairman of the USSR State Committee for Public Education, presents a project for the founding of a University of the Peoples of Europe. What he envisions is primarily a research institution devoted to the study of pan‐European problems of all sorts and the generalization of the solutions. The author suggests outlines of both the possible activities of such a university and of its organization. He believes that the institution should function under the auspices and with the support of Unesco.
