The European university landscape: A micro characterization based on evidence from the Aquameth project

This paper provides a new and systematic characterization of 488 universities, from 11 European countries: Finland, France, Germany, Hungary, Italy, Netherlands, Norway, Portugal, Spain, Switzerland and UK. Using micro indicators built on the integrated Aquameth database, we characterize the European university landscape according to the following dimensions: history/foundation of university, dynamics of growth, specialization pattern, subject mix, funding composition, offer profile and productivity.     

Microfluidic wet spinning of chitosan-alginate microfibers and encapsulation of HepG2 cells in fibers

The successful encapsulation of human hepatocellular carcinoma (HepG2) cells would greatly assist a broad range of applications in tissue engineering. Due to the harsh conditions during standard chitosan fiber fabrication processes, encapsulation of HepG2 cells in chitosan fibers has been challenging. Here, we describe the successful wet-spinning of chitosan-alginate fibers using a coaxial flow microfluidic chip. We determined the optimal mixing conditions for generating chitosan-alginate fibers, including a 1:5 ratio of 2% (w∕w) water-soluble chitosan (WSC) solution to 2% (w∕w) alginate solution. Ratio including higher than 2% (w∕w) WSC solution increased aggregation throughout the mixture. By suspending cells in the WSC-alginate solution, we successfully fabricated HepG2 cell-laden fibers. The encapsulated HepG2 cells in the chitosan-alginate fibers were more viable than cells encapsulated in pure alginate fibers, suggesting that cross-linked chitosan provides a better environment for HepG2 cells than alginate alone. In addition, we found that the adhesion of HepG2 cells on the chitosan-alginate fiber is much better than that on the alginate fibers.     

Adolescents’ future wishes and fears in their acculturation process

In this study we aim at learning about adolescents’ future fears and wishes from different cultural origins with a view to finding implications for intervention in the furthering of their satisfaction and social integration in their acculturation process. The study sample comprised 938 secondary school students—64.4% Spanish, 19.7% South American and 12.8% African. Wishes and fears were evaluated by means of two open questions and the answers were categorized following traditional content analysis methodology. Results show that the adolescents wish for a satisfactory job, family and economic situation, and that they are concerned about aspects such as their own health and that of their family, the possibility of having a precarious job, isolation from their family of origin, and not forming a family. The findings also allow us to give differential profiles according to the cultural origin of the adolescents.

The Congress for Cultural Freedom, <Emphasis Type="Italic">Minerva</Emphasis>, and the Quest for Instituting “Science Studies” in the Age of Cold War

The Congress for Cultural Freedom is remembered as a paramount example of the “cultural cold wars.” In this paper, I discuss the ways in which this powerful transnational organization sought to promote “science studies” as a distinct – and politically relevant – area of expertise, and part of the CCF broader agenda to offer a renewed framework for liberalism. By means of its Study Groups, international conferences and its periodicals, such as Minerva, the Congress developed into an influential forum for examining the ways Big Science impacted the relations between science, society, and politics, thus constituting a semi-institutional niche for Science Studies before its professionalization within academia during the 1970s. I argue that the Congress contributed to the construction of public space in which the relations between science, society and politics were debated, and science was reconceptualized as a social activity. The vision of “science studies” the CCF-associated intellectuals promulgated was different from the science studies we know today. Yet, this alternative vision, in which the issues of science politics appeared inseparable from those of science policy, science organization, and science governance, constituted the “pre-history” of science studies today.     

Factors that Differentiate Mathematics Students in Cyprus,Hong Kong,and the USA

The purpose of this study was twofold: to examine how attitudinal and instructional variables differentiated 4th-grade students in Cyprus, Hong Kong, and the USA; and to determine how those variables were related to math performance on the TIMSS test. A discriminant analysis was performed to examine how those variables differentiated the students in the 3 countries. The most striking result was that the students from all 3 countries, who were similar to the average students in Cyprus, had the highest achievement within their countries. Thus, 4th-grade students who liked math, who thought it was important to do well in math for their friends, who did not need private instruction, and who had not been taught using computers or small group procedures, tended to be the better students. However, students who were similar to the average USA student had the lowest achievement within each of the 3 countries.     

Sex education and cultural values: experiences and attitudes of Latina immigrant women

The paper aims to further explore the role that culture plays in the provision and assimilation of sex education among Latina immigrants in the USA. To accomplish this, researchers conducted focus groups and interviews with 30 women from Central and South America who have lived in the USA for at least five years. Participants were asked to reflect on their experience with sex education in their home country and in the USA, and to assess how their attitudes towards sex education may impact their behavioural choices as parents and as sexually-active women. The findings demonstrate a wide range of views that did not follow patterns by common demographical proxy variables, suggesting that such variables are not enough to predict adoption of new cultural values that are different from their family's traditional norms. Instead, adherence to traditional cultural beliefs appeared to be a better predictor of attitudes and behaviours.     

A Theory of Questions and Question Asking

This article focuses on knowledge goals, that is, the goals of a reasoner to acquire or reorganize knowledge. Knowledge goals, often expressed as questions, arise when the reasoner's model of the domain is inadequate in some reasoning situation. This leads the reasoner to focus on the knowledge it needs, to formulate questions to acquire this knowledge, and to learn by pursuing its questions. I develop a theory of questions and of question asking, motivated both by cognitive and computational considerations, and I discuss the theory in the context of the task of story understanding. I present a computer model of an active reader that learns about novel domains by reading newspaper stories.
