Postural leaning direction challenges the manifestation of tendon vibration responses at the ankle joint

In this study, we examined the interaction between central and peripheral proprioceptive afferent pathways by applying ankle tendon vibration during postural leaning in different directions. Twenty young participants stood for 60s over the midline of two adjacent force platforms in (a) neutral stance distributing Body Weight (BW) equally between the platforms, (b) forward leaning transferring 80% of BW to the front platform and (c) backward leaning transferring 80% of BW to the rear platform. Participants controlled the degree of leaning by receiving on-line visual feedback of BW distribution matched to a target line. Vibration (80 Hz, 1.5–1.8 mm) was applied over the Achilles or tibialis anterior tendon during the middle 20s of standing. This induced a postural shift towards the vibration side and an increase in the variability of the BW distribution that was greater in backward compared to forward leaning. EMG responses to tendon vibration were independent of the leaning direction. Antagonistic activity also increased in response to vibration, the amplitude of this increase however was direction dependent. These results favor the hypothesis about the central co-modulation of the vibration evoked proprioceptive inflow based on postural and visual feedback rather than muscle tension constraints.     

The vision heuristic: Judging music ensembles by sight alone

Team effectiveness and group performance are often defined by standards set by domain experts. Professional musicians consistently report that sound output is the most important standard for evaluating the quality of group performance in the domain of music. However, across six studies, visual information dominated rapid judgments of group performance. Participants (1062 experts and novices) were able to select the actual winners of live ensemble competitions and distinguish top-ranked orchestras from non-ranked orchestras based on 6-s silent video recordings yet were unable to do so from sound recordings or recordings with both video and sound. These findings suggest that judgments of group performance in the domain of music are driven at least in part by visual cues about group dynamics and leadership.     

Metaphorical sense-making: visual-narrative language portraits of South African students

This article reflects on a creative visual-narrative approach to understanding South African students’ lived experiences of languages. Data were collected in two interviews: the first entailing a biographical history and the drawing of a linguistic portrait on a simple body outline and the second a narrative interview utilising the portrait generated in the first as a basis for talking about language and identity. Framing the research process in this creative visual mode shifts the focus of narrative talk, simultaneously grounding it in affective, embodied experience, and enabling a reflexive position from which to analyse the taken-for-granted role of language in the minutiae of everyday life. The theoretical lenses of identity and subjectivity are invigorated through these metaphorical representations, and new creative possibilities are released for analysing the role of language in mediating shifting power dynamics in post-apartheid and postcolonial South African life.     

Behold … All Things New: Uppsala 1968 and Its Mediatization as Film

The 4th Assembly of the World Council of Churches (WCC) in 1968 occurred during a period of increasing influence of the media in shaping society and culture. The documentary film Behold … All Things New, produced by Radio Sweden for the WCC's 1968 assembly in Uppsala, reflected this development. It was, however, both a promotional tool for the church and a sort of documentary. This article analyzes the film from the context of church media relations, examining the strengthened mediatization of the religious arena in the 20th century and giving close attention to the circumstances of the film's production, its narrative techniques, and visual realization. In this way, the film is made accessible as a historical source for the WCC and thus also for the history of the globalization of churches. The film places into perspective the connection between mediatization and secularization, as it represents the churches' integration into modern media society with all of its visual symbols of globality, ecumenism, and willingness to enter into dialogue.     

Central Asia as the economic and geopolitical tension nexus: Some implications for the world futures

During the last millennium the world economic and geopolitical conflicts were to a great extent connected: different crises in the World System's evolution stimulated geopolitical shifts and vice versa. This article argues that in the 15th century different geopolitical events and conflicts in Central Asia initiated the fall of the previous World System and the rise of the new one. This transformation resulted in the fall of overland and river trade routes, including the Great Silk Route, which passed through Central Asia. World trade shifted to sea and ocean routes, and European countries became the center of the new World System. Now, in the beginning of the 21st century a new transformation of the World System is underway. The center of economic and political development is migrating gradually to the East: this is why the geopolitical role of the Central Asian states is increasing. Central Asian states are a very important part of the New Silk Route; this route is to connect Eastern Asia with Europe and the Middle East. The United States, China, Russia, and other states are ardently competing to control the New Silk Route. Hence, different geopolitical, social, and military conflicts are probable in Central Asia. So economic and political integration in Eurasia between Russia, China, the United States and Central Asian states is very important for the geopolitical stabilization of the region. The article evaluates the main scenarios of geopolitical changes in Central Asia.     

Religion and politics: examining the impact of faith on political participation

This study examines the relationship between religion and political activity. It theorises religious influences on political activity and tests the impact of various religious factors on political participation in a large cross-national sample (1981–2014). This study integrates longitudinal data from the aggregated World Values Survey with country-level data in the hierarchical multilevel analysis that allows teasing out the individual-level religious influences, including membership in religious organisations, religiosity and self-identification with various religious denominations, and the country-level impacts. The temporal and spatial coverage of the data used in the study includes more than 65% of the world’s population. The seven types of political participation examined in the study include signing petitions, joining in boycotts, participating in demonstrations, taking part in unofficial strikes, occupying buildings and factories, voting and membership in political parties. We find that religion matters but not always in the expected ways. Religiosity, by itself, often serves as a deterrent rather than mobilising force for political engagement, regardless the denominational differences. It is the membership in religious organisations and other voluntary associations of a secular nature that make individuals more likely to engage in political activity.     

When family and research clash: The role of autobiographical emotion in the production of stories of the Italian civil war, 1943–1945

This paper engages the emotional side of Second World War storytelling practices and research. Specifically, it explores how a politics of trust and togetherness animates communities of remembrance concerning the anti-Fascist Resistance experience in northern Italy. I reflect on my encounter with memories of wartime violence through the lens of autobiographical emotion. In a region torn asunder by conflicting stories of loss and violence during the anti-Nazi resistance and civil war, I possess a dual identity of researcher and Partisan's grandchild. This carries a powerful emotional bond of ethical obligations that cannot be ignored in the research process. Drawing on affect theory, I contextualize my oral history fieldwork experience in relation to that emotional bond.     

A dissociation between selective attention and conscious awareness in the representation of temporal order information

Previous electrophysiological studies have shown that attentional selection processes are highly sensitive to the temporal order of task-relevant visual events. When two successively presented colour-defined target stimuli are separated by a stimulus onset asynchrony (SOA) of only 10 ms, the onset latencies of N2pc components to these stimuli (which reflect their attentional selection) precisely match their objective temporal separation. We tested whether such small onset differences are accessible to conscious awareness by instructing participants to report the category (letter or digit) of the first of two target-colour items that were separated by an SOA of 10, 20, or 30 ms. Performance was at chance level for the 10 ms SOA, demonstrating that temporal order information which is available to attentional control processes cannot be utilized for conscious temporal order judgments. These results provide new evidence that selective attention and conscious awareness are functionally separable, and support the hypothesis that attention and awareness operate at different stages of cognitive processing.
