Impossible Participation

The chapter critiques the rise of participation in art since the 1990s – a development that sees artists and curators searching continually for new and increased levels of audience inclusion. While there has been much discussion about what might be gained by participating in an artwork, we ask what might be lost by this act. We also question the extent to which participation is a useful social or aesthetic strategy in circumstances where it remains bound by the institutional structures of the artworld. For this reason, our work is an attempt to transform the broader ‘apparatus of art’ and to create works in which the roles assigned to individuals and groups remain fluid and subject to continuous negotiation. As a means of an attempt at resisting absorption into the institutional structures of the artworld, we privilege a form of participation that remains immanent in the work, but that never crystallizes into a single or definable role. Kathryn Brown , art historian and editor of Interactive Contemporary Art, says, ‘It is, perhaps, a fitting end to the discussions of the present volume that the most interesting and valuable form of participation envisaged by Freee is one that must remain impossible.’

Incipient turn-to-turn winding fault diagnosis of power transformers by the on-load exciting current Extended Park`s Vector Approach

This paper presents the application of the on-load exciting current Extended Park's Vector Approach for diagnosing incipient turn-to-turn winding faults in operating power transformers. Experimental and simulated test results demonstrate the effectiveness of the proposed technique, which is based on the spectral analysis of the AC component of the on-load exciting current Park's Vector modulus.

Transformers on-load exciting current Park`s vector approach as a tool for winding faults diagnostics

This paper presents the development of a new approach for diagnosing the occurrence of inter-turn short-circuits in the windings of three-phase transformers, which is based on the on-line monitoring of the on-load exciting current Park's Vector patterns. Experimental and simulated results demonstrate the effectiveness of the proposed technique for detecting winding inter-turn insulation faults in operating three-phase transformers.

Detection of trasformer intermittent winding faults by the on-load exciting current Park`s vector approach

This paper presents the application of the on-load exciting current Park's Vector Approach for diagnosing permanent and intermittent turn-to-turn winding faults in operating power transformers. First, an experimental investigation of the behaviour of the transformer under the occurrence of both permanent and intermittent winding faults is presented. Finally, experimental test results demonstrate the effectiveness of the proposed diagnostic technique, which is based on the on-line monitoring of the on-load exciting current Park's Vector patterns.

EU water framework directive: will the nitrate load reduction from diffuse sources produce the same results in all estuaries?

The impact of urban waste-water and non-point nitrate discharges in estuarine and near-shore coastal waters are analyzed. The study is focused on the effects of applying the European directives 91/271/EEC and 91/676/EEC to these systems. 4 Portuguese estuaries and two coastal lagoons with different characteristics are studied. A modelling system is applied and calibrated in each system. Three nitrate load scenarios are examined. It is shown that the morphologic and hydrodynamic characteristics of the domain largely control the ecological processes in these systems. The primary production limitation factors are split into “biologic” and “hydrodynamic” components. The physical limitation due to hydrodynamic and residence time is the most important factor. The combined limitation of “biologic” factors (temperature, light and nutrients availability) control productivity only in the systems where physical limitation is not important.

La transformation des pratiques professionnelles chez les enseignants du secondaire : analyse des effets de la participation aux cercles d'apprentissage et d'inclusion

Cette recherche poursuit l'objectif général d'analyser la transformation des pratiques professionnelles des enseignants du secondaire à l'égard des élèves en difficulté intégrés en classe régulière suite à leur participation au dispositif des cercles d'apprentissage et d'inclusion (CAI). La problématique met en évidence les changements de paradigmes associés aux multiples réformes du système de l'éducation et les difficultés auxquelles sont confrontés les enseignants depuis l'instauration de la nouvelle Politique de l'adaptation scolaire au Québec. Les nouvelles visées ministérielles prônent désormais une éducation de qualité pour tous. La notion d'équité est à la base des actions qui doivent guider les pratiques de l'école inclusive. Cependant, les écrits sur le sujet soulignent le manque de connaissances des enseignants pour adapter leurs pratiques professionnelles aux élèves en difficulté intégrés dans leur classe (Gaudreau, Legault, Brodeur, Hurteau, Dunberry, Séguin, Legendre, 2008; MacKay, 2006). Ces auteurs suggèrent à cet égard, la nécessité d'implanter dans les milieux des dispositifs de formation continue axés sur l'acquisition de connaissances quant aux processus d'apprentissage des élèves, aux pratiques pédagogiques différenciées et aux stratégies favorables aux apprentissages. La méthodologie utilisée s'inscrit dans une démarche de co-construction des savoirs. (Desmarais, Boyer et Dupont, 2005) avec des enseignants désireux de travailler sur l'amélioration de leurs pratiques professionnelles à l'égard des élèves en difficulté intégrés en classe régulière au secondaire. Ainsi, des groupes de réflexions portant sur l'analyse de l'expérience vécue par les enseignants ont permis d'offrir un accompagnement et un cadre défini pour la collecte de données (Boudreault et Kalubi, 2006). Des entrevues semi-dirigées ont complété notre collecte de données à la fin du projet afin de préciser et de nuancer les propos recueillis lors des groupes de réflexion. Les résultats obtenus nous ont permis d'identifier certaines conditions à mettre en place dans l'accompagnement des enseignants en exercice et de mieux comprendre les difficultés relatives à un tel dispositif.

Effet ajouté et participation des pères à un programme d'entraînement aux habiletés parentales

Selon l'American Psychiatric Association (APA, 2004), les troubles du comportement perturbateur (TCP) se divisent en trois diagnostics : le trouble d'attention avec ou sans hyperactivité (TDA/H), le trouble d'opposition avec ou sans provocation (TOP) et le trouble des conduites (TC). Les programmes d'entraînement aux habiletés parentales (PEHP) sont reconnus comme étant des pratiques probantes dans le traitement de ces troubles (Hartman, Stage et Webster-Stratton, 2003; Kazdin, 2001; Nock & Kazdin, 2001; Webster-Stratton, 2007; Weersing & Weisz, 2000). Toutefois, les pères s'impliquent généralement moins que les mères dans ce type d'intervention alors que leur implication dans la vie de l'enfant est associée à de nombreux bénéfices (Coplin & Houts, 1991; Lamb, 2004). Les objectifs de cette étude sont de vérifier si la participation des pères au programme est similaire à celle des mères et de vérifier quel est l'effet ajouté de leur participation à l'efficacité d'un PEHP sur l'enfant, les parents et la famille. Au total, 33 familles ont participé au programme et leur présence est justifiée par le TDA/H de leur enfant. Le groupe "sans père" (SP) est formé de 9 mères qui sont venues seules aux rencontres et le groupe "avec pères" (AP) est formé de 24 pères et mères venus ensemble. Ils ont participé au programme Ces années incroyables qui inclut 16 rencontres de groupe de deux heures chacune. L'évaluation est faite avant le programme (pré-test, Tl), à la fin (post-test, T2) et 6 mois plus tard (suivi, T3) et inclut des mesures du comportement de l'enfant, des pratiques éducatives parentales, du stress parental, du sentiment d'autoefficacité parental et du fonctionnement familial. Les résultats démontrent que les pères accompagnés sont moins assidus que les mères accompagnées, mais ne se distinguent pas des mères qui sont venues seules. Leur engagement dans les rencontres est toutefois similaire à celui des mères. Les analyses de variance à mesures répétées démontrent une amélioration plus immédiate des comportements extériorisés chez l'enfant dont le père était présent au programme. Suite au programme (post-test), sa présence n'a pas d'effet sur le stress parental, mais six mois après la fin de ce dernier (suivi), les mères qui y étaient seules se sentent plus stressée [i.e. stressées] que celles qui étaient accompagnées du père. Toutefois, très peu d'effets ont été décelés sur les pratiques éducatives parentales et le fonctionnement familial. La discussion analyse ces résultats et y fait suivre des retombées cliniques.

Visuoperceptual deficits and participation in older adults after stroke

Introduction: Visuoperceptual deficits frequently occur after a stroke but little is known about how they evolve over time. These deficits may have an impact on participation in daily activities and social roles. Objectives: The aims were to 1) track changes over six months in the visual perception of older adults with persistent visuoperceptual deficits after a stroke; 2) examine if these changes differed between participants who had and had not received rehabilitation services; and 3) verify if participation differed between participants with and without visuoperceptual deficits. Methods: Visual perception as well as participation of 189 older adults who had had a stroke were evaluated in the first month (T1) after being discharged home from an acute care hospital (NO REHAB group) or rehabilitation unit (REHAB group). For visual perception, only participants presenting deficits at T1 were re-evaluated at 3 months (T2; n=93), and those with deficits at T2 were re-evaluated at 6 months (T3; n=61). Results: A total of 57 people (30.2%) had visuoperceptual deficits six months after discharge home. Despite persistent deficits, approximately 45% of the participants in the two groups improved while 50% of the NO REHAB group and 24.3% of the REHAB group deteriorated. Changes in the mean scores on the MVPT-V were similar in the two groups. Participation, and especially participation in social roles, was more restricted in participants with visuoperceptual deficits (p<0.001), whatever the severity of the stroke. Conclusion: Visuoperceptual deficits are common post-stroke. However, they evolve differently in different people and are associated with a reduction in participation.

Rhetoric and Realities of London 2012 Olympic Education and Participation ‘Legacies’: Voices from the Core and Periphery

A legacy emphasis was one of the fundamental pillars of the London 2012 Olympic Games. The notion of an Olympic legacy was predicated on assumptions that the event’s value would not purely derive from the sporting spectacle, but rather, from the ‘success’ of enduring effects met out in London and across the country. For physical education students and practitioners, Olympic legacy agendas translated into persistent pressure to increase inspiration, engagement, participation and performance in the subject, sport and physical activity. Responding to this context, and cogniscent of significant disciplinary scholarship, this paper reports initial data from the first phase of a longitudinal study involving Key Stage Three (students aged 11-13) cohorts in two comparable United Kingdom schools: the first an inner-city (core) London school adjacent to the Olympic Park in Stratford, East London (n=150); the second, a (peripheral) school in the Midlands (n=198). The research involved the use of themed questionnaires focusing on self-reported attitudes toward the Olympic Games, and, experiences of physical education, sport and physical activity. Students from both schools demonstrated a wide variety of attitudes toward physical education and sport; yet, minor variances emerged regarding extreme enthusiasm levels. Both cohorts also expressed considerably mixed feelings toward the impending Olympic Games. Strong and variable responses were also reported regarding inspiration levels, ticketing acquisition and engagement levels. Consequently, this investigation can be read within the broader context of legacy debates, and, aligns well with physical educationalists’ on-going discomfort regarding legacy imperatives being enforced upon the discipline and its practitioners. Our work reiterates a shared disciplinary scepticism that while an Olympic Games may temporarily affect young peoples’ affectations for sport (and maybe physical education and physical activity), it may not provide the best, or most appropriate, mechanism for sustained attitudinal and/or social changes en masse.

An investigation of container train service provision and load factors in Great Britain

The continued growth in the volume of international trade poses considerable economic and sustainability challenges, particularly as transport routes become more congested and concern grows about the role of transport movements in accelerating climate change. Rail freight plays a major role in the inland transport of containers passing through the main British container ports, and potentially could play a more significant role in the future. However, there is little detailed understanding of the nature of this particular rail market, especially in terms its current operating efficiency. This paper examines container train service provision to/from the four main ports, based on analysis of a representative survey of more than 500 container trains between February and August 2007. The extent to which the existing capacity is utilised is presented, and scenarios by which the number of containers carried could be increased without requiring additional train service provision are modelled, to identify the theoretical potential for greater rail volumes. Finally, the paper identifies the challenges involved in achieving higher load factors, emphasising the importance both of wider supply chain considerations and government policy decision-making.

Distributed Agent-Based Load Balancer for Cloud Computing

In this paper we present a concept of an agent-based strategy to allocate services on a Cloud system without overloading nodes and maintaining the system stability with minimum cost. To provide a base for our research we specify an abstract model of cloud resources utilization, including multiple types of resources as well as considerations for the service migration costs. We also present an early version of simulation environment and a prototype of agent-based load balancer implemented in functional language Scala and Akka framework.
