Discussing the Greenhouse Effect: children's collaborative discourse reasoning and conceptual change

In environmental education the construction of appropriate knowledge is not enough, but is undoubtedly a fundamental component of individual and collective environmental responsiveness. The aim of this study was to investigate fifth graders' changes of conceptions about the greenhouse effect and global warming, due to socio‐cognitive interaction developed in small and large group discussions in an authentic classroom context during the implementation of an environmental education curriculum unit. We hypothesized that a classroom transformed into a community of discoursei.e. a learning environment which stimidates and supports giving verbal explanations, comparing and critically evaluating different points of view on the examined environmental phenomenon, would be a fruitful breeding ground for knowledge revision. The results show that classroom discussions, the core of the proposed learning activity, led the children, although at different levels, to the integration of new scientific knowledge into their conceptual ecology, based on the personal revision of pre‐instructional conceptions. As hypothesized, a high positive correlation was found between conceptual change and metaconceptual awareness of the changes in pre‐existing representations of the examined phenomenon. Some implications are drawn from the standpoint of environmental education.     

STEM colonization: Applying hard sciences' socio-organisational patterns and evaluation procedures to the soft sciences in Croatia

Academic systems are undergoing changes in which the social organisation of research as well as patterns of scientific productivity in the humanities and social sciences progressively resemble those in hard sciences. The hard and soft sciences are increasingly converging. This development can be observed in (a) publishing patterns, (b) the division of research, and (c) the internationalisation of research. This study explored the extent to which these changes occurring in academic systems in terms of a transformation of disciplinary practices are also becoming a trend in transitional post-socialist countries. We used Croatia as a case of a post socialist transitional context and compared it to Slovenia, a country with a similar past but somewhat different science policies and strategies. The results point to increasing convergence in some soft disciplines, visible in projectification and internationalisation of academic work as well as a significant change in the publishing patterns.     

Students as political actors? Similarities and differences across six European nations

Drawing on data from students, higher education staff and policymakers from six European countries, this article argues that it remains a relatively common assumption that students should be politically engaged. However, while students articulated a strong interest in a wide range of political issues, those working in higher education and influencing higher education policy tended to believe that students were considerably less politically active than their predecessors. Moreover, while staff and policy influencers typically conceived of political engagement in terms of collective action, articulated through common reference to the absence of a ‘student movement’ or unified student voice, students’ narratives tended not to valorise ‘student movements’ in the same way and many categorised as ‘political’ action they had taken alone and/or with a small number of other students. Alongside these broad commonalities across Europe, the article also evidences some key differences between nation-states, institutions and disciplines. In this way, it contributes to the comparative literature on young people’s political engagement specifically, as well as wider debates about the ways in which higher education students are understood.     

The influence of technology-mediated and in-person communication on student satisfaction: The moderating role of national culture

This article analyses the effects of technology-mediated (i.e., social media) and in-person communication (i.e., non-verbal cues) on student satisfaction in a higher education context. Data were collected among 221 college students from the University of Valencia (UVEG) in Spain and analysed from the perspective of the respondents' national culture. Contrary to expectations, the results show that neither one of the social media aspects drives student satisfaction, thus providing support for the technology paradox literature. Instead, three non-verbal communication cues are found to influence student satisfaction, i.e., paralanguage, kinesics, and chronemics. The moderating role of national culture on the examined relationships is also considered. The results reveal that national culture seems to only affect the relationship between chronemics and satisfaction.     

Adolescents' and Parents' Evaluations of Helping Versus Fulfilling Personal Desires in Family Situations

A sample of 118 predominantly European American families with early and middle adolescents ( M _ages= 12.32 and 15.18 years) and 1 parent evaluated hypothetical conflicts between adolescents' and parents' requests for assistance versus the other's personal desires. Evaluations differed by level of need, but in low-need situations, adolescents viewed teens as more obligated to help parents than did parents, whereas parents rated it as more permissible for teens to satisfy personal desires than did teenagers. Justifications for helping focused on concern for others, role responsibilities, and among parents, psychological reasons. Middle adolescents reasoned about role responsibilities more and viewed satisfying personal desires as less selfish than did early adolescents, but satisfying personal desires was seen as more selfish by parents of middle than early adolescents. Implications for adolescent–parent relationships are discussed.     

Personality of elite male and female chess players and its relation to chess skill

Whereas a lot of studies examine cognitive processes in chess players, personality profiles of elite chess players are still not described well. The aim of this study was to examine personality of strong chess experts and its influence on chess skill. We tested elite male and female chess players with Freiburg Personality Inventory Revised (FPI-R), which also provides population norms for males and females. Elite male players' personality profile did not significantly differ from the population norms. Female players were more satisfied with life, had less physical complaints and higher achievement motivation in comparison with female population norms. Personality was also related with chess skill but showed different patterns in males and females. Stronger male players were more introverted, while we found the opposite pattern in female players. These results indicate that personality plays an important role in the highest level of complex intellectual activities.     

Truncation error analysis in computing of SEP and SEP floor for partially coherent receiver of MPSK signals over composite fading channels

In this paper, we analyze detection of multilevel phase-shift keying (MPSK) signals transmitted over a Gamma shadowed Nakagami-m fading channel. We derive novel analytical expression, in terms of Meijer’s G function, for Fourier coefficients of the probability density function of the received signal composite phase. Under the assumption of the imperfect reference signal extraction in the receiver, which is performed from the pilot signal, the analytical expression is derived for the symbol error probability (SEP) in the form of convergent series. The existence of the error floor is identified, and expression for its computation is provided. Mathematical proofs for convergence of Fourier series are provided for both SEP and SEP floor, and novel expressions of upper bounds for truncation errors are derived in terms of elementary mathematical functions. The convergence rate of the derived expressions is examined. Numerical results are confirmed independently by Monte-Carlo simulations.     

Carnival supporters,hooligans, and the ‘Against Modern Football’ movement: life within the ultras subculture in the Croatian context

Abstract

This paper is based on sociological research on Torcida, football supporters of Hajduk Football Club from Split (Croatia). We used ethnographic methodology throughout 37 months of fieldwork (from July 2012 to August 2015) and conducted 23 in-depth interviews with hardcore members of Torcida. Although our research included the distinction between carnival supporters and hooligans, these elements are much more interconnected within the hard core of Torcida than they are separate. Because of various social efforts (sometimes coordinated with other Ultras groups) against the local and global football establishment – especially against the Croatian Football Federation and UEFA – we consider Torcida part of a wide, heterogeneous social movement against modern football. This corresponds to the self-reflection and self-perception of the core group of Torcida. Ultras subculture in the Croatian context represents a key (although not the only) social actor in bearing the AMF movement.
