Towards a probabilistic model for supporting collaborative information access

In information retrieval research, models and systems traditionally assume that a single person is querying and reviewing the results. However, several empirical studies of professional practice identified collaboration during IR as everyday work patterns in order to solve a shared information need and to benefit from the diverse expertise and experience of the team members. Moreover, most IR systems that are employed in professional work routines are designed for individual use and prototype collaborative systems are too limited to support use in todays work practice. To bridge this gap, this papers develops and formalizes a decision theoretic approach towards supporting a team of people that explicitly set out together to resolve a shared information need. We develop a formal cost model for collaborative IR that considers the trade-off between estimated relevance of a document as well as estimated document redundancy. From this cost model, we use a decision theoretic approach to derive the notion of activity suggestions, that is, a formal optimum criterion that describes optimum collaboration strategies in IR as the solution of an integer linear program. Those collaboration strategies are suggested to team members with the aim to facilitate the collaborative performance of information retrieval tasks. We demonstrate the application of our model by means of search result division in two collaborative search tasks. In the conducted experiments, we study the effects of different domain knowledge and resulting relevance assessments of team members in four different conditions. The gathered results indicate that our approach can improve the retrieval effectiveness of teams in recall-oriented tasks.     

Outdoor recreation in exergames: a new step in the detachment from nature?

A new teaching aid—exergames—is increasing in popularity in schools and is regarded as an interesting, varied and effective way of improving students’ fitness. These exercise television games often contain references to physical activities carried out in different outdoor landscapes. The purpose of this article is to examine the views of landscape and nature offered by the games and the consequences this may have for students’ relationships with nature and future environmental commitment. The methodological approach used is companion meaning analysis: the meaning of nature that follows when playing the games. The results show a controlled landscape that is perfectly arranged for the activity (functional specialisation). It is an obvious anthropocentric base and commands an instrumental value where nature is valuable because it satisfies our felt preferences (demand value). Exergames can thus be seen as a further step in an ongoing detachment process from the physical landscape (indoorisation).

Learning in and from the West: international students and international women’s organisations in the interwar period

This article explores the importance of higher education to international women’s organisations such as the International Federation of University Women, the International Council of Women, the International Alliance of Women and Women’s International League for Peace and Freedom, and asks how studying abroad contributed to the international cooperation and understanding promoted by these organisations in the interwar period. In particular, it assesses how the movement of ‘Eastern’ women, especially East Asian, to the West for educational purposes at the beginning of the twentieth century benefited the expansion of these organisations beyond Europe, North America and white settler countries such as Australia and New Zealand between the world wars, and to what extent the experiences of international students in the ‘West’ influenced their political activities back home and their involvement in international women’s organisations.     

An educational tool for outdoor education and environmental concern

The purpose of this paper is to suggest an outdoor education model that respects the need to critically discuss the general belief in a causal relationship between experiences of nature, environmentally-friendly attitudes and behavioural change, but that at the same time respects the legitimate claims on the part of outdoor education practice for concretisation and clarity. The foundation of this model consists of a combination of theoretical perspectives and models that have been generated through a number of Swedish interdisciplinary research projects concerning human interrelationships with the landscape during the last decade. The paper first focuses on the subtleties of environmental concern with the aid of an environmentally historic model of how care for nature and environmental protection successively developed during the last century. It then addresses different aspects of outdoor education by presenting two specific models: a model of two principally diverse motives for this education, and a model of three different approaches to the landscape when executing outdoor education. In the final section these models are assembled in a suggested model for outdoor education and environmental concern, and identify a handful of main educational paths. The paper concludes with a brief discussion about continued research and examples of what can be regarded as particularly important developments and additions to the suggested model.     

Psychometric analysis of a measure of socio-emotional development in adolescents

This is a psychometric analysis of an instrument to assess the socio-emotional development of school students, How I Feel (HIF), developed as a situational judgment test, with scoring based on expert judgments. The HIF test was administered in grades 4–9, 1999–2005. Internal consistency, retest reliability, and year-to-year stability were satisfactory, and the HIF instrument appears sensitive to intervention effects. Sex differences and associations with substance use and other instruments support construct validity. A significant negative trend was found across grades, attenuated in a group receiving socio-emotional training. The HIF test has limited discriminatory power among individuals with high socio-emotional maturity.     

Deliberative Teaching: Effects on Students’ Democratic Virtues

Since the early-2000s, deliberative democratic theory has influenced the debate on teaching. Proponents of deliberation in education have argued that deliberative communication as a teaching model enhances both subject knowledge and democratic virtues among students. However, empirical support for this assumption is weak. The aim of this article is to empirically test the assumptions made by the proponents of deliberative teaching. This study uses a field experimental research design. The study was carried out in a civics course in Swedish upper-secondary schools in both vocational programs and programs preparing students for ensuing studies. To some extent, the results support the hypothesis derived from deliberative theory. Deliberative teaching seems to enhance democratic virtues among students in vocational programs.
