Perhaps Triangulation Isn’t Enough: a Call for Crystallization as a Methodological Referent in NOS Research

This research compares the methodological tools employed in NOS research, with analysis of what the comparison implies about the structure of nature of science knowledge. Descriptions of practicing teachers’ nature of science conceptions were compared based on data collected from forced choice responses, responses to a qualitative survey, and course writing samples. Participants’ understandings were scored differently on the Views of Nature of Science Questionnaire (VNOS) than the forced-choice measure, Scientific Thinking and Internet Learning Technologies (STILT). In addition, analysis of the writing samples and observations combined with interviews portrayed more sophisticated, but more variable, understandings of the nature of science than was evidenced by either the survey or the forced-choice measure. The differences between data collection measures included the degree to which they drew upon context bound or context general reasoning, the degree to which they required students to move beyond the simple intelligibility of their responses and allowed students to explore the fruitfulness of the constructs, as well as the degree to which they revealed the interconnection of participants NOS conceptions. In light of the different portrayals of a participants NOS conceptions yielded by these different measures, we call for the use of crystallization as a methodological referent in research.

Role of Ashwangandha (Withania Somnifera) in Immune Modulation: Proposed Influence in Immune-Regulation

The immune system evolved to protect organisms from an infinite variety of disease-causing agents but to avoid harmful responses to self. However, such a powerf~dl efense mechanism requires regulation. Immune regulation includes homeostatic and cellmediated targeted mechanisms to the activation, differentiation and function of antigen-triggered immuno-competent cells and irnmunoregulatory cells. The regulation of the immune system has been a major challenge for the management of autoimmune disorders, tumor immunity, infectious diseases and organ transplants. However, irnmuno-modulatory procedures used by modern medicine to induce immunoregulatory function have deleterious side effects. Ashwangandha (Withania somnifera), an herb used in Ayurvedic medicine is being tested and used in experimental and clinical cases with potential immuno-modulatory functions without any side effects. Here we propose future usages of Ashwangandha for immuno-regulatory function in translational research.

The Socioeconomics of Consumption: Solutions to the Problems of Interest, Knowledge, and Identity

This paper is a review of the socio-economic literature on consumption. Considering consumption as a social activity, it examines how consumption solves the problems of interest, knowledge, and identity. It also discusses the main themes and important contributions in each category and offers suggestions for further research.

Cognition and Student Learning Through the Arts

An increasing number of recent research studies suggest connections between cognition, social and emotional development, and the arts. Some studies indicate that students in schools where the arts are an integral part of the academic program tend to do better in school than those students where that is not the case. This study examines home/school factors that contribute most to variance in student learning and achievement and the arts from over 8,000 students in grade 5. The findings suggest in-school arts programs may have less of an impact on student achievement than proposed by previous research.
