Reviewing the differences in size,composition and structure between the personal networks of high‐ and low‐performing students

An interesting aspect in the current literature about learning networks is the shift of focus from the understanding of the “whole network” of a course to the examination of the “personal networks” of individual students. This line of research is relatively new, based on small‐scale studies and diverse analysis techniques, which demands for more empirical research in order to contextualize the findings and to meta‐analyze the research methods. The main objective of this paper is to review two research questions posed by a previous British Journal of Educational Technology contribution by Shane Dawson in order to know whether the differences in personal network composition impact on the performance of students. The two questions were defined by Dawson as follows: (1) Are there significant differences in personal network composition between high‐ and low‐performing students? and (2) Do high‐performing students have larger personal networks than their low‐performing peers? In addition, the “clustered graphs” method used in this study allows the inclusion of the structural analysis of personal networks. In doing so, a new research question is addressed: (3) Are there significant differences in personal network structure between high‐ and low‐performing students? This paper tries to answer these questions in the context of two undergraduate, inter‐university and fully online courses, and two different technology‐enhanced learning environments (a virtual learning environment and a personal learning environment) where interactions took place indirectly through shared resources. The results show that the network behaviors of high‐ and low‐performing students' are strongly correlated, and that high‐performing students developed larger personal networks than low performers.     

Adaptation of the Multidimensional Trauma Recovery and Resilience (MTRR) questionnaire in a sample of Chilean mothers with a history of child abuse

OBJECTIVE: Adaptation of the Multidimensional Trauma Recovery and Resilience (MTRR) in a Chilean sample. METHOD: Participants were 80 mothers drawn from two large metropolitan areas (Santiago and Temuco). Sample participants (in a case control design) were redivided in two groups: 40 mothers identified as physical abusers with history of physical child abuse and 40 mothers identified as nonabusers with history of physical child abuse. Groups were matched on 5 sociodemographic variables. Reliability analysis, item analysis, and group comparisons on the 8 scales of the instrument were performed. RESULTS: Interrater agreement level was .79 (Kendall's W coefficient) and the internal consistency as measured by Cronbach's alpha coefficient was .75. Twenty-five items (26.3%) significantly discriminated between the groups. Group comparison tests (Wilcoxon Rank-sum Test) also indicated that six of the eight domains discriminated between the groups. CONCLUSION: In our sample, the instrument has reliable results which discriminate between the studied groups. These preliminary findings support future work toward the development of a Chilean version of this instrument.     

Science Letters:Demonstration of a new biosensing concept for immunodiagnostic applications based on change in surface conductance of antibodies after biomolecular interactions

Electrical conductivity in biomolecules and other large polymeric systems has become an important topic of current research. Schlag et al.(2000a; 2000b) demonstrated that charge migration in proteins is highly efficient although the mechanistic origin is still debated and largely unknown even though various models have been proposed by Weinkauf et al.(1995; 1996; 1997). According to them, the charge transfer between amino acids takes place by hole hopping between local sites of lowest ionizati…     

Trading quality across borders: colonial discourse and international quality assurance policies in higher education

Accountability and quality assurance have become central discourses in higher education policy throughout the world. However, accountability and quality assurance involve power and control. Practices and ideas about quality developed in the Global North are spreading rapidly across the Global South, leading to increased uniformity in the approaches to quality assurance. Given the significant asymmetries that divide the Global North and Global South, this article maps interdiscursive relations among key texts that influence policy development on international quality in higher education, and explores the applicability of colonial discourse as a perspective for understanding this increasing international convergence.     

Factors Leading to Success in Diversified Occupation: A Livelihood Analysis in India

Purpose: Livelihood diversification is a sound alternative for higher economic growth and its success or failure is conditioned by the interplay of a multitude of factors. The study of the profile of the farmers in which they operate is important to highlight the factors leading to success in diversified livelihoods. Design/Methodology/Approach: A total of 160 households of farmers were selected randomly and were interviewed to collect primary data for the study. To measure the success of diversified occupation a success–failure scale was developed following the steps used by Singh et al., ‘t’ statistics was used to compare the two groups. Discriminant function analysis was used to identify the factors determining success and failure in diversified occupation. Findings: The study revealed that 53% of the diversifiers were successful in their diversified activities. Around 62.50% diversifiers under the high success category were adopted non-farming nature of diversification along with farm diversification. Number of livestock holding, resource mobilisation potentiality, contact with extension personnel, distance from market, share of non-farm income, credit-seeking behaviour and dependency ratio were major characters discriminating successful diversifiers from unsuccessful diversifiers. Practical Implications: The paper would be useful for the researchers and policy-makers to assess and compare the livelihood security of different rural communities in the country. Originality/Value: The study was originally conducted by the authors. Nothing similar has been previously published or is currently under consideration for publication by another journal.     

Motivational profiles as a combination of academic goals in higher education

The aim of the current study was to obtain information from students in higher education on different motivational profiles that resulted from the combination of three academic goals (i.e. learning goals (LG), performance-approach goals and performance-avoidance goals). Moreover, information related to the relevance of each goal within each motivational profile was explored to explain conditions closely related to the academic engagement. The sample consisted of 2556 students from five Spanish universities. Motivational profiles were obtained by using cluster analysis followed by a relevance analysis of each goal within each motivational profile. The results support the hypothesis concerning motivational profiles, and further suggest for motivational profiles with a predominance of LG to be more adaptive. According to our findings, high level of LG in one’s motivational profile appear to be a powerful protective factor in maintaining high interest in academic work, as well as high control beliefs and self-efficacy.
