Film policy and the emergence of the cross-cultural: exploring crossover cinema in Flanders (Belgium)

With several films taking on a cross-cultural character, a certain ‘crossover trend’ may be observed within the recent upswing of Flemish cinema (a subdivision of Belgian cinema). This trend is characterized by two major strands: first, migrant and diasporic filmmakers finally seem to be emerging, and second, several filmmakers tend to cross the globe to make their films, hereby minimizing links with Flemish indigenous culture. While paying special attention to the crucial role of film policy in this context, this contribution further investigates the crossover trend by focusing on Turquaze (2010, Kadir Balci) and Altiplano (2009, Peter Brosens & Jessica Woodworth)

Media and violent conflict : Halil Dağ, Kurdish insurgency, and the hybridity of vernacular cinema of conflict

This article analyses the life and work of Halil Dag (1973-2008), a filmmaker who worked within the Kurdish insurgent movement, with two critical goals. First, the authors use Dag's case to conceptualize vernacular cinema of conflict, defying traditional dichotomies between mainstream/vernacular, and fiction/non-fiction. Secondly, through Dag's case they seek to better understand the role of vernacular cinema of conflict for the Kurdish culture of resistance and the PKK insurgent movement in particular. Empirically, the article discusses unique ethnographic records (interviews and personal correspondence with Dag) and a qualitative content analysis of his major films. The authors argue that the concept of vernacular cinema of conflict can serve a better comprehension of the hybrid character and impact of filmmaking in conflict zones

Nollywood online: between the individual consumption and the communal reception of Nigerian films among African diaspora

Various video-on-demand (VOD) platforms streaming Nigerian films have popped up on the Internet since 2011. These VOD platforms facilitate the consumption of Nigerian films among African diaspora. Despite an increasing academic interest for Nollywood audiences, these new modes of viewing Nigerian films online have yet to be explored. In this article, we will therefore give attention to the consumption and reception of Nigerian films on the Internet among African diaspora of Nigerian, Ghanaian and Cameroonian origin in the cities of Antwerp and Ghent, Belgium. In this study, we adopted a media ethnographic approach, including fieldwork and semi-structured in-depth interviews. Although scholars have suggested that the Internet fragments and individualizes film viewing, the results of this study show that indeed online Nigerian films are most often watched individually by the respondents, yet the reception of the films remains a social practice of shared meaning-making

Evolution and development of fruits of Erycina pusilla and other orchid species

Fruits play a crucial role in seed dispersal. They open along dehiscence zones. Fruit dehiscence zone formation has been intensively studied in Arabidopsis thaliana. However, little is known about the mechanisms and genes involved in the formation of fruit dehiscence zones in species outside the Brassicaceae. The dehiscence zone of A. thaliana contains a lignified layer, while dehiscence zone tissues of the emerging orchid model Erycina pusilla include a lipid layer. Here we present an analysis of evolution and development of fruit dehiscence zones in orchids. We performed ancestral state reconstructions across the five orchid subfamilies to study the evolution of selected fruit traits and explored dehiscence zone developmental genes using RNA-seq and qPCR. We found that erect dehiscent fruits with non-lignified dehiscence zones and a short ripening period are ancestral characters in orchids. Lignified dehiscence zones in orchid fruits evolved multiple times from non-lignified zones. Furthermore, we carried out gene expression analysis of tissues from different developmental stages of E. pusilla fruits. We found that fruit dehiscence genes from the MADS-box gene family and other important regulators in E. pusilla differed in their expression pattern from their homologs in A. thaliana. This suggests that the current A. thaliana fruit dehiscence model requires adjustment for orchids. Additionally, we discovered that homologs of A. thaliana genes involved in the development of carpel, gynoecium and ovules, and genes involved in lipid biosynthesis were expressed in the fruit valves of E. pusilla, implying that these genes may play a novel role in formation of dehiscence zone tissues in orchids. Future functional analysis of developmental regulators, lipid identification and quantification can shed more light on lipid-layer based dehiscence of orchid fruits

High levels of non-activated receptors in glucocorticoid-sensitive S49wt mouse lymphoma cells incubated with dexamethasone

Upon agonist binding the heteromeric glucocorticoid receptor complex under goes a conformational change (receptor activation). This event involves the dissociation of a dimer of 90 kDa heat shock proteins. Whereas receptor activation in cytosolic assays is both rapid and irreversible, less is known about the receptor activation and translocation in intact cells during challenge with an agonist. In this paper we report on the receptor status of glucocorticoid-sensitive murine S49 lymphoma cells during dexamethasone exposure. By three different assays, ligand (re)binding, nuclear translocation and hsp90 co-immunoprecipitation, it was found that the majority of the glucocorticoid receptor protein was in a non-activated conformation. Furthermore, prolonged exposure to dexamethasone did not result in increased levels of activated receptors. By assessing receptor activation in situ we found that physiological temperature was less effective in dissociating hsp90 compared to room temperature. These findings indicate that the physiological temperature negatively controls receptor activation, probably due to a thermolabile interaction between the hormone and its cognate receptor.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/31269/1/0000175.pd

Context-dependent combination of sensor information in Dempster–Shafer theory for BDI

© 2016, The Author(s). There has been much interest in the belief–desire–intention (BDI) agent-based model for developing scalable intelligent systems, e.g. using the AgentSpeak framework. However, reasoning from sensor information in these large-scale systems remains a significant challenge. For example, agents may be faced with information from heterogeneous sources which is uncertain and incomplete, while the sources themselves may be unreliable or conflicting. In order to derive meaningful conclusions, it is important that such information be correctly modelled and combined. In this paper, we choose to model uncertain sensor information in Dempster–Shafer (DS) theory. Unfortunately, as in other uncertainty theories, simple combination strategies in DS theory are often too restrictive (losing valuable information) or too permissive (resulting in ignorance). For this reason, we investigate how a context-dependent strategy originally defined for possibility theory can be adapted to DS theory. In particular, we use the notion of largely partially maximal consistent subsets (LPMCSes) to characterise the context for when to use Dempster’s original rule of combination and for when to resort to an alternative. To guide this process, we identify existing measures of similarity and conflict for finding LPMCSes along with quality of information heuristics to ensure that LPMCSes are formed around high-quality information. We then propose an intelligent sensor model for integrating this information into the AgentSpeak framework which is responsible for applying evidence propagation to construct compatible information, for performing context-dependent combination and for deriving beliefs for revising an agent’s belief base. Finally, we present a power grid scenario inspired by a real-world case study to demonstrate our work

Pride and popcorn: consuming the idea of community at film screenings in the Turkish diaspora

A range of studies have revealed the interrelatedness of identity construction, community formation and media among diasporas, mostly focusing on domestic contexts. Seeking to add further nuance to the understanding of the social lives of diasporas, we concentrate on media culture in the public environment of the film theatre. The significance of diasporic film consumption is investigated through a local audience study of Turkish film screenings in Antwerp. The phenomenon of the screenings was analysed through a multi-method approach, including 536 questionnaires among audiences, 19 in-depth interviews and 3 group interviews, along with previous findings (on distribution and exploitation) of the same project. The results show that Turkish films are almost exclusively attended by people with Turkish roots, creating a Turkish diasporic space within the boundaries of the urban and the public. The audience study shows that the screenings fulfil a major social role but also affect understandings of community
