    Shifting inequalities? Patterns of exclusion and inclusion in emerging forms of political participation

    No full text
    Previous research has found a steady increase in the number of people involved in emerging forms of civic engagements such as Internet campaigns, protests, political consumerism, and alternative lifestyle communities. Verba et al. (1995) have established that various forms of political participation in the United States follow a pattern of structural inequality, based on income, education, gender and civic skills. The growing popularity of emerging action repertoires forces us to re-evaluate the claims of this literature. Do these patterns of inequality persist for the emerging action repertoires across advanced industrialized democracies, or are they becoming even stronger, as Theda Skocpol (2003, 2004) argues? The results of this cross-national analysis with longitudinal comparisons suggest that gender inequalities in emerging political action repertoires have substantially declined since the 1970s, whereas other forms of inequality have persisted. However, contrary to the more pessimistic claims about a "participation paradox", there is no evidence that inequality based on socio-economic status has substantially increased since the 1970s. --

    Decentering: Creation of a proxy measure and relationship with cognitive tasks

    No full text
    Decentering refers to an ability to notice day-to-day stressful mental experiences (negative thoughts, feelings and memories) and psychologically ‘step back’ from them to observe them from an objective self-perspective, without perseverating on the themes they represent (Bennett et al. 2021; Bernstein et al. 2015). Decentering has the capacity to dampen the impact and distress associated with psychological stressors that can otherwise increase mental ill health in vulnerable individuals. Importantly, the strengthening of decentering-related abilities has been flagged as a core component of psychological interventions that treat and prevent anxiety and depression (Bennett et al., 2021). Few studies (if any) have investigated whether adolescents are proficient at decentering. A clear barrier has been the absence of child and adolescent friendly measures of decentering-related abilities. Even less research attention is given to the impact of psychological decentering on cognitive performance in emotional contexts. Investigating the impact of decentering on cognitive performance is essential to elucidate the mechanisms by which it might impact mental health. Understanding the relationship between decentering and day-to-day emotional fluctuations, simulated in these tasks, may also allow the enhancement of current mental health interventions. To address these research gaps, we will conduct a secondary analysis of a dataset that contains information about mental health and affective cognitive control in a large community sample of adolescents (the MYRIAD Theme 1A dataset; N = 553, %female = 31.28%, age = M 14.37 SD 1.77). Data were originally collected from 2017 until 2018 as part of a broader investigation into the efficacy of school-based mindfulness training. This project investigates emotional and cognitive correlates of decentering in a pre-existing dataset

    The discovery of SycO reveals a new function for type three secretion effector chaperones

    No full text
    The Type Three Secretion (T3S) system is a device used by many Gram-negative pathogens that allows bacteria to deliver effector proteins straight into the eukaryotic cell cytosol. These effectors interfere with various signaling pathways to subvert the host cell functions. The secretion machinery of the T3S system consist of a basal body spanning the bacterial inner and outer membrane followed by a stiff hollow needle outside the bacterium. The fully assembled secretion apparatus constitute a continuous hollow conduit that connects the bacteria to the eukaryotic target cell. After cell contact, virulence proteins -called effectors- are injected directly into the cytosol of the host cell via the T3S apparatus. Several effectors of the T3S system require the assistance of specific cytosolic chaperones to be efficiently exported. There are three classes of T3S chaperones. Effector proteins are assisted by Class I chaperones. Although Class I chaperones are well characterized, their main function is still a matter of controversy. In this thesis, we demonstrate that orf155 encodes a specific chaperone for the effector YopO that we called SycO. We showed that SycO enhances YopO secretion in vitro and is required for translocation of YopO into infected cells. By pulldown assay we demonstrated that residues 20 to 77 of YopO are required and sufficient for SycO binding. Using crosslinking experiments and size exclusion chromatography analysis, we determined the stoichiometry of purified SycO and YopO-SycO complexes. SycO alone forms dimers in solution and the YopO-SycO complex has a 1:2 stoichiometry. These results suggested that SycO is a typical chaperone of the Class I. YopO is a serine/theronine kinase that interacts with Rho and Rac and disrupts the cytoskeleton of the target cells. YopO has been shown to localize at the cell plasma-membrane. By transfection of YopO-EGFP hybrid proteins into HEK293T cells, we demonstrated that the chaperone-binding domain (CBD) coincides with the membrane localization domain of YopO. Nevertheless, the CBD was not needed for the kinase activity of YopO. By ultracentrifugation, we also showed that the CBD causes YopO aggregation in the bacteria, when SycO does not cover it. Further, we show that the CBD of YopE and YopT also caused aggregation in the bacteria in the absence of SycE and SycT respectively. YopE, YopT and T3S effectors in other systems also act at the membrane of the eukaryotic host cell. We propose a new hypothesis concerning the role of T3S chaperones. The sub-cellular localization domain of effectors is aggregation-prone and creates the need for a chaperone inside bacteria. We propose that masking such aggregation-prone localization domains may be a general function for type III effector chaperones

    Du non-lieu au lieu : pratique spatiale et construction identitaire dans Texaco, de Patrick Chamoiseau

    [À l'origine dans / Was originally part of : Thèses et mémoires - FAS - Département de littérature comparée]Le présent ouvrage propose une lecture spatiale du roman Texaco, de l’auteur martiniquais Patrick Chamoiseau. Texaco retrace l’histoire de la Martinique, principalement celle de sa population noire créolophone, depuis le XIXe siècle – époque de la traite et de l’esclavage – jusqu’à la fin du XXe siècle. Considérant que l’identité d’un individu (ou d’une communauté) est étroitement corrélée au rapport qu’entretient celui-ci avec son espace de vie, notre travail vise à mettre au jour les particularités identitaires des personnages du roman au travers d’une analyse des espaces qu’ils occupent et façonnent dans le récit. En nous appuyant sur des concepts spatiaux empruntés à Henri Lefebvre (l’espace tripartite), à Michel de Certeau (le lieu, l’espace et la pratique spatiale) et à Marc Augé (le lieu et le non-lieu), nous souhaitons montrer de quelle manière et dans quelle mesure ces différentes entités spatiales expriment, consolident ou oblitèrent l’identité singulière des personnages chamoisiens, c’est-à-dire leur « créolité ».This work presents a spatial analysis of the novel Texaco, written by the Martinican author Patrick Chamoiseau. Texaco follows the story of Martinique, mainly its black Creole population, from the 19th century – the time of slave trade and slavery – until the end of the 20th century. Considering that the identity of an individual (or a community) is closely related to the link it maintains with its living space, our work aims to unveil the particularities of identity of the characters through the analysis of the spaces they occupy and create. Basing ourselves on spatial concepts borrowed from Henri Lefebvre (the tripartite space), Michel de Certeau (the space, the place and the spatial practices) and Marc Augé (the place and the non-place), we wish to show how and to what extent those different spaces express, consolidate or obliterate the distinct identity of Chamoisian characters, in other words their “creoleness”

    Perceptual and conceptual similarities facilitate the generalisation of instructed fear

    No full text
    Background and objectives: Learned fear can generalize to neutral events due their perceptual and conceptual similarity with threat relevant stimuli. This study simultaneously examined these forms of generalization to model the expansion of fear in anxiety disorders. Methods: First, artificial categories involving sounds, nonsense words and animal-like objects were established. Next, the words from one category were paired with threatening information while the words from the other category were paired with safety information. Lastly, we examined if fear generalized to (i) the conceptually related animal-like objects and (ii) other animal likeobjects that were perceptually similar. This was measured using behavioural avoidance, US expectancy ratings and self-reported stimulus valence. Results: Animal-like objects conceptually connected to the aversive words evoked heightened fear. Perceptual variants of these animal-like objects also elicit fear. Limitations: Future research would benefit from the use of online-US expectancy ratings and physiological measures of fear. Conclusions: Investigating the role of both perceptual and conceptual fear generalization is important to better understand the etiology of anxiety disorders symptoms.sponsorship: Marc Bennett is a doctoral student who is supported by the Flemish Research Council (FWO) under grant number G.0518.11 (awarded to Dirk Hermans and Frank Baeyens).

    Art and the artist in the literary works of Elsa Triolet

    No full text
    This thesis takes a representative selection of Triolet's works to study the themes of writing and creativity as they are presented in the novels. These are all portraits of artists and the accounts of the search for a synthesis of aesthetic freedom and ethical responsibility. It considers Triolet's importance as a foreign writer, adopting a new creative language to be adopted by a different cultural environment, to be essential in understanding her importance to the French literary tradition. By emphasising her formative years in the avant-garde circles of prerevolutionary Russia, my study demonstrates her considerable contribution to the meeting of Russian and French aesthetic theories. I extend this with close textual readings of certain works to demonstrate her techniques in novelistic construction which reveal many Formalist practices before Formalist works in translation made their official influence on creative methods. The introduction considers the reasons for Triolet's neglect as a writer. It then considers various contemporary and recent critical appraisals which indicate the interest she has received until present and which allow me to define my own critical approach. Part One traces Triolet's literary evolution from her formative years in Russia, through exile to her first publications in Russian. It then considers her insertion into French literary activity, and her association with the schools of socialist realism and the "nouveau roman". Part Two examines two traditional novels which portray the creative and metaphorical roles of the artist and his work, showing the constant conflict between private and public lives. In Part Three, I show how aspects of novelistic traditionalism are gradually foregrounded so that the work develops a dual-sided character where it both narrates and examines the processes of its own narration. In Part Four, this move to highly self-conscious aesthetics demonstrates an idiosyncratic exploration of new paths for the novel that bring visual, auditive and cinematographic media into the traditional domain of written art. Accompanying the very post-modernist experimentation, I show how this research within the novel into the novel's own future has an ethical and redemptive purpose whose final conclusion is that creativity and human freedom are inexorably interwoven

    Communication, Communion and Conflict in the Theologies of Gregory Baum and Patrick Granfield

    No full text
    Degree Awarded: Ph.D. Systematic Theology. The Catholic University of AmericaCommunion, communication, and conflict are interrelated realities of great importance for the life and mission of the church. These realities themselves and the relationships between them are in need of theological refinement and assessment, because conflict necessarily affects the church's ability to communicate the message of salvation, and to experience communion.Within a North American and Roman Catholic context, Canadian theologian Gregory Baum (b.1923) and U.S. theologian Patrick Granfield (1930-2014) present ways of perceiving the relationships between these three realities. Through an analysis of the salient dimensions of their respective theologies, this dissertation explores their respective understandings of the church, and identifies ways in which their approaches complement each other, with particular attention paid to the themes of communion, communication and conflict.Baum reflected on these three realities with respect to the church's life and mission to the world, articulating an ecclesial spirituality. Granfield did so primarily with respect to the church's institutional life. Considering their works together offers a means to deepen the church's experience of the mystery of communion via a renewed approach to its communication of the divine promise, while acknowledging conflict as a force which need not be destructive, but which can be harnessed for creative growth.The works of both men show that the implementation of an ecclesiology of communion in the church today requires an awareness that communion is more than simply a theological notion of union with God, that communication in the church is more than speech alone, and that conflict in the church need not be divisive or destructive. Rather, communion in the church must always be concretely expressed in order to be experienced, communication is the sharing of the whole person, and conflict can be attended to in a way which strengthens communion and does not undermine it. By their attention to these three realities in the church, both Baum and Granfield have provided important reflections, not only on how the church lives and functions, but on how it can remain faithful to its divine calling and mission in a continually challenging and complex era

    The German Occupation in recent French fiction : an analysis of the literary “mode retro”

    No full text
    This thesis attempts to analyse and characterise the mode rétro, the remarkable renewal of interest in the German Occupation of France, which is coloured by an extensive re-evaluation of the period's significance. An introduction places this fashion in its literary, social and historical context, revealing how, from 1940 to 1969, a collective and predominantly Gaullist 'myth' of the Resistance became established, with the result that the national response to invasion was accepted to be one of wide-spread heroism and revolt. Part I studies the reaction to such résistancialisme, showing how this orthodox interpretation of events was undermined and, for many, discredited, and offering explanations of the timing and direction of the new view. Part II focuses on the fiction, memoirs, autobiographies and biographies of the younger authors, those who have no direct adult experience of the années noires. It is suggested that their obvious obsession with absent parent-figures reflects their awareness that the past has been misrepresented and their heritage rendered problematic. Their sole means of escape from this predicament, their only source of emotional relief is seen to lie in the creation of a personal account of the early 1940s running contrary to the prevalent orthodoxy, the fabrication of a 'counter-myth'. It is thus the notion of myth which links the various sections of the survey, and so gives the thesis its overall unity
