Hierarchical web resources retrieval by exploiting Fuzzy Formal Concept Analysis

In recent years, knowledge structuring is assuming important roles in several real world applications such as decision support, cooperative problem solving, e-commerce, Semantic Web and, even in planning systems. Ontologies play an important role in supporting automated processes to access information and are at the core of new strategies for the development of knowledge-based systems. Yet, developing an ontology is a time-consuming task which often needs an accurate domain expertise to tackle structural and logical difficulties in the definition of concepts as well as conceivable relationships. This work presents an ontology-based retrieval approach, that supports data organization and visualization and provides a friendly navigation model. It exploits the fuzzy extension of the Formal Concept Analysis theory to elicit conceptualizations from datasets and generate a hierarchy-based representation of extracted knowledge. An intuitive graphical interface provides a multi-facets view of the built ontology. Through a transparent query-based retrieval, final users navigate across concepts, relations and population.     

Negotiating the Contested Terrain of Equity-Focused Change Efforts in Schools: Critical Race Theory as a Leadership Framework for Creating More Equitable Schools

Educational leaders attempting to enact equity-focused change in their schools are frequently met with fierce opposition by politically powerful parents whose children are well served by the status quo. The purpose of this conceptual article is to: (a) explore the utility of Critical Race Theory as a framework for helping K-12 school leaders anticipate and make sense of resistance to change efforts aimed at creating greater educational equity for underserved students, and (b) suggest ways that school leaders can more effectively engage in equity reforms in their schools. To do this, we examine a highly contested public debate over a recent equity-focused change effort at Berkeley High School (BHS)—a large, racially and socioeconomically diverse public school in Northern California. Using the events at BHS as an example, we argue that change efforts could be undertaken more effectively by: (a) identifying and addressing the underlying property interests up front, (b) anticipating how majoritarian narratives rooted in “colorblindness” and deficit thinking would be employed as a means for obscuring and maintaining unequal access to scarce resources, and (c) focusing on specific areas of interest convergence.     

Diversity and intergroup contact in higher education: exploring possibilities for democratization through social justice education

This study contributes to research linking diversity and higher education teaching to democratic learning outcomes. It explores processes and outcomes associated with the intergroup contact of Black and White students enrolled in two sections of a diversity education course at a public university in the southeastern United States. The goals of this study were: (1) to explore the intergroup dynamics that emerged when students interacted in both sections of the course; and (2) to identify student support for intergroup cooperation as a result of their experiences in the course. While one section of the course experienced a high degree of intergroup conflict, students in both sections reported support for intergroup cooperation at the end of the course.     

Assessment of drug information resource preferences of pharmacy students and faculty

A 39-item survey instrument was distributed to faculty and students at Wingate University School of Pharmacy to assess student and faculty drug information (DI) resource use and access preferences. The response rate was 81% (n = 289). Faculty and professional year 2 to 4 students preferred access on laptop or desktop computers (67% and 75%, respectively), followed by smartphones (27% and 22%, respectively). Most faculty and students preferred using Lexicomp Online for drug information (53% and 74%, respectively). Results indicate that DI resources use is similar between students and faculty; laptop or desktop computers are the preferred platforms for accessing drug information.

Initial Science Teacher Education in Portugal: The Thoughts of Teacher Educators About the Effects of the Bologna Process

Between the 1980s and 2007, Portugal used to have one-stage (5-year period) initial teacher education (ITE) programs. In 2007 and consistent with the Bologna process guidelines, Portuguese teacher education moved toward a two-stage model, which includes a 3-year undergraduate program of subject matter that leads to a licenciatura (or bachelor) degree and a 3-year professional master in the teaching of a subject. The way that teacher educators perceive the ITE programs effects the education of prospective teachers and consequently the future of science education. This paper aims at analyzing how science teacher educators perceived the changes that took place in this formal way of educating junior school (7th–9th grades) and high school (10th–12th grades) science teachers in Portugal, due to the implementation of the Bologna guidelines. To attain the objectives of the study, 33 science teacher educators including science specialists and science education specialists answered an open-ended online questionnaire, which focused on the strengths and weaknesses of the pre- and post-Bologna ITE programs, the overall quality of teacher education and measures for improving ITE. The results indicate that science teacher educators were quite happy with all of the ITE models, but they expressed the belief that both the science and the teaching practice components should be strengthened in the post-Bologna masters in teaching. Meanwhile, changes were introduced in Portuguese educational laws, and they proved to be consistent with the opinions of the participants. However, the professional development of teacher educators along with evidence-based ITE programs seems to be necessary conditions for overcoming the challenges that teacher education is still facing in Portugal and worldwide.
