Yugoslavia: other modernities,other histories

The Non-Aligned Movement was a transnational political project, a coalition of small and middle-sized states, mostly former colonies and developing countries, from the global south or the Third World. It was formed in 1961 in Yugoslavia at the Belgrade summit. The NAM represented the first major disruption in the Cold World map, a quest for alternative political alliances, for “alternative mundialization.” Culture was accorded particular importance in the NAM, despite the fact that it never took center-stage at summits and conferences. However, NAM’s cultural politics strongly condemned cultural imperialism and epistemic colonialism. Western (European) cultural heritage was to be understood in terms of “juxtaposition”; this heritage would be interwoven with and into the living culture of the colonized, and would not simply be repeated under new (political) circumstances. Consequently art and culture in the NAM were largely about politics and history, or to put it differently, they were a way of staking a claim to history. It seems the movement was somehow aware of the fact that this was the only way it could enter the world’s (cultural) space on an equal footing. There existed a heterogeneous artistic production, a variety of cultural politics and extensive cultural networks which enriched the cultural landscape of the NAM and enabled discussions about the meaning of art outside the Western canon.     

Effects of 8-week endurance and resistance training programmes on cardiovascular stress responses,life stress and coping

ABSTRACT

This study tested the effect of 8-week endurance and resistance training programmes on cardiovascular stress responses, life stress, and coping. Fifty-two untrained but healthy female students were randomised to an 8-week endurance training, an 8-week resistance training, or a wait list control group. Before and after the training intervention, we assessed the groups’ cardiorespiratory fitness (VO2max test), self-reported life stress, coping strategies and cardiovascular reactivity to and recovery from a standardised laboratory stressor. Both endurance and resistance training programmes caused physiological adaptation in terms of increased VO2max after the intervention. For stress and coping parameters, participants in the training groups improved cardiovascular recovery from stress and reported having less stress in their everyday life after the intervention than participants in the control group, while the two training groups did not differ from each other. We did not find any significant differences in heart rate reactivity and coping strategies between the study groups. These results partly support that exercise training has stress-reducing benefits regardless of the type of exercise. Both endurance and resistance exercise activities may be effectively used to improve stress regulation competence while having less impact on changing specific coping strategies.     

Measurement of fluid flow generated by artificial cilia

We observed and measured the fluid flow that was generated by an artificial cilium. The cilium was composed of superparamagnetic microspheres, in which magnetic dipole moments were induced by an external magnetic field. The interaction between the dipole moments resulted in formation of long chains-cilia, and the same external magnetic field was also used to drive the cilia in a periodic manner. Asymmetric periodic motion of the cilium resulted in generation of fluid flow and net pumping of the surrounding fluid. The flow and pumping performance were closely monitored by introducing small fluorescent tracer particles into the system. By detecting their motion, the fluid flow around an individual cilium was mapped and the flow velocities measured. We confirm that symmetric periodic beating of one cilium results in vortical motion only, whereas asymmetry is required for additional translational motion. We determine the effect of asymmetry on the pumping performance of a cilium, verify the theoretically predicted optimal pumping conditions, and determine the fluid behaviour around a linear array of three neighbouring cilia. In this case, the contributions of neighbouring cilia enhance the maximal flow velocity compared with a single cilium and contribute to a more uniform translational flow above the surface.     

Didactic strategies in early science teaching

The purpose of the article is to show the results of empirical research on the prevailing teaching strategies for teaching contents of the subject environmental studies (specifically when dealing with natural content) in the first triennium of the nine‐year primary school in the Republic of Slovenia. The information was obtained through a survey of 141 teachers from 60 randomly selected primary schools in the Republic of Slovenia. We found that teachers use different teaching strategies as students gain knowledge through experience, participation in education, they express their opinion, views, solve simple problems and explore. Such notice shall then direct the transmissions to the transaction and transformation, which was an important objective of the reform of the subject.
