Investigating relationships within and between category networks in Wikipedia

This work maps and analyses cross-citations in the areas of Biology, Mathematics, Physics and Medicine in the English version of Wikipedia, which are represented as an undirected complex network where the entries correspond to nodes and the citations among the entries are mapped as edges. We found a high value of clustering coefficient for the areas of Biology and Medicine, and a small value for Mathematics and Physics. The topological organization is also different for each network, including a modular structure for Biology and Medicine, a sparse structure for Mathematics and a dense core for Physics. The networks have degree distributions that can be approximated by a power-law with a cut-off. The assortativity of the isolated networks has also been investigated and the results indicate distinct patterns for each subject. We estimated the betweenness centrality of each node considering the full Wikipedia network, which contains the nodes of the four subjects and the edges between them. In addition, the average shortest path length between the subjects revealed a close relationship between the subjects of Biology and Physics, and also between Medicine and Physics. Our results indicate that the analysis of the full Wikipedia network cannot predict the behavior of the isolated categories since their properties can be very different from those observed in the full network.     

People and Technology Today： Some Educational Implications

The present article approaches some of the educational implications borne by humanity with technological progress We begin by pointing out significant data that classify what is considered relevant. Then, confronting the future is discussed by analyzing the attitudes necessary to promote the goals. Confronted with these challenges, three possible focuses are suggested in accordance to the novel realities issued from science and technology： The first is the revitalization of humanism; The second is, the society of knowledge calls for both ＂radicalism and responsibility＂, which is also a response to our own decisions, without avoiding their consequences nor discharging them in others; The third is, understanding the true and full significance of solidarity. Finally, some approaches and educational suggestions are highlighted allowing parents, professors and students the greatest opportunity for profiting from the limitless resources that science and technology provide us for personal growth.     

Latinx* popular culture imaginaries: examining Puerto Rican children’s social discourses in interpreting telenovelas

Abstract

In this paper, we present a collaboration project within one urban Puerto Rican classroom, focused on constructing a critical literacy inquiry curriculum grounded in the students’ out-of-school literacy practices in their communities, including their experiences with media and popular culture. We focused on a critical literacy and media inquiry unit centered on the students’ self-selected subject of the telenovela. Here, we examine one student’s work to highlight two overarching findings: (1) the visibility of the students’ complex understanding of the media landscapes in telenovelas, particularly the construction of dominant social discourses across telenovela worlds, and (2) the ways that bringing children’s mediatized cultural imaginaries in their creative work supports an approach to literacy in classrooms, where explorations of discourses of power emerge from the students’ knowledge. In order to articulate how children actively examine and construct discourses across multiple social worlds, we examine these findings using the Four Resource Model, and elements of discourse analysis, as theoretical and analytical frameworks, focusing on the construction of identities, worlds and meanings in relation to the social discourses of telenovelas.     

Investigating returns to scope of research fields in universities

For policy-makers and managers of research organizations, improvement in performance is a constant objective. The potential presence of returns to scope of fields of research could influence decisions in planning the fields of activity of the research organization and the spatial positioning of its researchers in function of their specializations. We investigate the possible presence of returns to scope and the relation between scope of fields in an organization and intensity of interdisciplinary collaboration. The results, from analyzing the scientific collaborations of Italian university researchers over the years 2004–2008, seem to indicate that in general the scope of the research fields has no impact on the productivity of research or the intensity of interdisciplinary collaboration.

On time-varying collaboration networks

The patterns of scientific collaboration have been frequently investigated in terms of complex networks without reference to time evolution. In the present work, we derive collaborative networks (from the arXiv repository) parameterized along time. By defining the concept of affine group, we identify several interesting trends in scientific collaboration, including the fact that the average size of the affine groups grows exponentially, while the number of authors increases as a power law. We were therefore able to identify, through extrapolation, the possible date when a single affine group is expected to emerge. Characteristic collaboration patterns were identified for each researcher, and their analysis revealed that larger affine groups tend to be less stable.     

University-industry research collaboration: a model to assess university capability

Scholars and policy makers recognize that collaboration between industry and the public research institutions is a necessity for innovation and national economic development. This work presents an econometric model which expresses the university capability for collaboration with industry as a function of size, location and research quality. The field of observation is made of the census of 2001–2003 scientific articles in the hard sciences, co-authored by universities and private enterprises located in Italy. The analysis shows that research quality of universities has an impact higher than geographic distance on the capability for collaborating with industry. The model proposed and the measures that descend from it are suited for use at various levels of administration, to assist in realizing the “third role” of universities: the contribution to socio-economic development through public to private technology transfer.     

Factors affecting corporate image from the perspective of distance learning students in public higher education institutions

New information technologies enable different interactions in the educational environment, affecting how the image of educational institutions adopting distance-learning programmes is perceived. This article identifies factors affecting the perception of corporate image from the viewpoint of distance-learning students at public higher education institutions. The results indicate that the institution’s image is a translation of impressions generated from the individual’s interaction with various organisational components, based on relevant cognitive and affective aspects according to the way of observing the environment. The study demonstrated both the multidimensionality of the image and that the institution’s overall image is associated most strongly with its affective image. The study also demonstrated that the virtual environment was the factor most strongly associated with affective image.
