Soccer,nationalism and the media in contemporary Spanish society: La Roja,Real Madrid & FC Barcelona

This essay examines the relationship between nationalism and soccer in contemporary Spain. Firstly, it pays close attention to the roles of the national team and the rivalry between Real Madrid and FC Barcelona in articulating conflictual social agendas. Secondly, it compares how Spanish and Catalan media utilize the Spanish soccer team success to articulate clashing forms of nationalism. It scrutinizes a wide range of journalistic interventions as well as the TV coverage of the national soccer team in the Spanish and Catalan media to determine how they constantly re-articulate the role of soccer in defining the distinguishing characteristics of the nation. Lastly, it studies a series of soccer-related cultural and social practices such as street rallies, gatherings and celebrations in order to determine their role within contemporary nationalism in Spain.     

V + H: Hybrid architecture for DSS and OLTP

Previous research has been done to identify the best pragmatic approach that DBMSs must follow to manage different workloads. Some approaches have followed the “One size fits all” approach, trying to incorporate all features in a row-oriented DBMS (also called horizontal) to manage both OLTP and DSS workloads. Additionally, there have been specialized DBMS, following a columnar approach (also called vertical), that focuses on the growing demand to efficiently manage DSS workloads. This paper proposes a combination of both vertical and horizontal DBMS to best manage OLTP and DSS workloads. We have used mature, commercially available products from a single vendor and developed a custom middleware Decision Query Module that identifies the best option for most efficient execution of a query. This V + H architecture also offers the functionality of a mirrored DB without paying twice for storage.     

The Effectiveness of Concept Maps in Teaching Physics Concepts Applied to Engineering Education: Experimental Comparison of the Amount of Learning Achieved With and Without Concept Maps

A study was conducted to quantify the effectiveness of concept maps in learning physics in engineering degrees. The following research question was posed: What was the difference in learning results from the use of concept maps to study a particular topic in an engineering course? The study design was quasi-experimental and used a post-test as a measuring instrument. The sample included 114 university students from the School of Industrial Engineering who were divided into two equivalent homogeneous groups of 57 students each. The amount of learning attained by the students in each group was compared, with the independent variable being the teaching method; the experimental group (E.G.) used concept maps, while the control group (C.G.) did not. We performed a crossover study with the two groups of students, with one group acting as the E.G. for the topic of optical fibers and as the C.G. for the topic of the fundamental particles of matter and vice versa for the other group. For each of the two topics studied, the evaluation instrument was a test of 100 dichotomous items. The resulting data were subjected to a comparative statistical analysis, which revealed a significant difference in the amount of learning attained by the E.G. students as compared with the C.G. students. The results allow us to state that for the use of concept maps, the average increment in the E.G. students’ learning was greater than 19 percentage points.

The h-bubble

Hypes occur in every domain of human behavior, including scientific research. We show in this contribution that journals and authors who studied the h-index benefited in terms of short-term citations. As, moreover, the introduction of the h-index is more a ‘clever find’ than a first rate intellectual achievement, its rise can be compared to a stock market bubble.     

The Role of Context for Characterising Students’ Strategies when Estimating Large Numbers of Elements on a Surface

Causal Learning Across Culture and Socioeconomic Status

Extensive research has explored the ability of young children to learn about the causal structure of the world from patterns of evidence. These studies, however, have been conducted with middle-class samples from North America and Europe. In the present study, low-income Peruvian 4- and 5-year-olds and adults, low-income U.S. 4- and 5-year-olds in Head Start programs, and middle-class children from the United States participated in a causal learning task (N = 435). Consistent with previous studies, children learned both specific causal relations and more abstract causal principles across culture and socioeconomic status (SES). The Peruvian children and adults generally performed like middle-class U.S. children and adults, but the low-SES U.S. children showed some differences.     

Multilateral agencies and higher education reform in Latin America

During the last decade, the debate over higher education took up a significant space on the agendas of various international agencies, including multilateral development banks and other intergovernmental agencies. This fact points to the importance of the subject within a broader discussion that refers to national development projects and their articulation within the new international economic and political order. In this context, the purpose of this article is to discern the principal lines of argument at work and their implications for the transformation of higher education in Latin America. To this end, we have chosen four cases that we consider relevant for the region: The United Nations Education, Science and Cultural Organization (UNESCO), the World Bank, the Economic Commission for Latin America and the Caribbean (ECLA) and the Interamerican Development Bank (IADB). In the first part of the text we characterize the particularities of each of these organizations, highlighting their relation with the processes of educational change. In the second, we approach the subject of the recommendations made by the multilateral agencies on change in the higher education systems in the world and, particularly, in the Latin American region.
