L’adoption du projet de loi n°21 et les effets sur la psychothérapie au Québec : une étude descriptive

Depuis l’arrivée de la psychologie dans les universités québécoises en 1872, la psychologie n’a cessé d’évoluer. Alors qu’autrefois aucune loi ne régissait la pratique de la psychothérapie et l’usage du titre de psychothérapeute, le gouvernement du Québec a adopté en 2009, le projet de loi 21. Ce mémoire retrace l’histoire de la psychologie au Québec ainsi que l’histoire de l’Ordre des psychologues du Québec en portant une attention particulière aux changements légaux concernant la règlementation de la pratique de la psychothérapie et l’usage de titres réservés. Afin de dresser un portrait de la psychothérapie au Québec deux ans après l’adoption de la Loi 28 (mieux connue sous le nom de projet de loi 21), trois banques de données de l’Ordre des psychologues ont été utilisées ( 1) «Membres», 2) «Psychothérapeutes» et 3) «Signalement psychothérapie»). De ces trois banques de données, deux sont construites à partir de formulaires remplis par les psychologues et psychothérapeutes. Des 8509 psychologues, 870 psychothérapeutes, et 524 dossiers de pratique illégale (usurpation de titres professionnels et/ou pratique illégale de la psychothérapie) inclus dans l’étude, des différences statistiquement significatives ont été remarquées pour ce qui est du sexe, de l’âge et de la langue maternelle. Toutefois, l’effet de taille était petit. Les différences les plus importantes étaient observables au niveau de la scolarité et de l’exercice de la psychothérapie. Les dispositions de la Loi modifiant le Code des professions et d’autres dispositions législatives dans le domaine de la santé mentale et des relations humaines n’étant en vigueur que depuis deux ans, il serait intéressant de suivre l’évolution de la psychothérapie et de la pratique illégale de la psychothérapie au Québec dans les prochaines années.

Modélisation de l'irradiance solaire totale et spectrale et applications à la chimie stratosphérique terrestre

Cette thèse présente des reconstructions de l'irradiance totale et spectrale durant les 400 dernières années à l'aide des modèles pour l'irradiance totale et l'irradiance spectrale dans l'ultraviolet développés à l'Université de Montréal. Tous deux sont basés sur la simulation de l'émergence, de la fragmentation et de l'érosion des taches solaires, qui permet d'obtenir une distribution de l'aire des taches sombres et des facules brillantes en fonction du temps. Ces deux composantes sont principalement responsables de la variation de l'irradiance sur l'échelle de temps de la décennie, qui peut être calculée en sommant leur émissivité à celle de la photosphère inactive. La version améliorée du modèle d'irradiance solaire spectrale MOCASSIM inclut une extension de son domaine spectral entre 150 et 400 nm ainsi que de son domaine temporel, débutant originalement en 1874 et couvrant maintenant la période débutant en 1610 jusqu'au présent. Cela permet de reconstruire le spectre ultraviolet durant le minimum de Maunder et de le comparer à celui du minimum de 2009. Les conclusions tirées de cette étude spécifient que l'émissivité dans l'ultraviolet était plus élevée en 2009 que durant le minimum de Maunder, que le niveau de base de la photosphère non magnétisée contribuait pour environ les deux tiers de cette différence et que les structures magnétiques restantes étaient responsables pour le tiers restant. Le modèle d'irradiance totale a vu son domaine temporel étendu sur la même période et une composante représentant le réseau magnétique de façon réaliste y a été ajoutée. Il a été démontré que les observations des 30 dernières années ne sont bien reproduites qu'en incluant la composante du Soleil non magnétisé variable à long terme. Le processus d'optimisation des paramètres libres du modèle a été effectué en minimisant le carré de la somme de l'écart journalier entre les résultats des calculs et les données observées. Les trois composites disponibles, soit celui du PMOD (Physikalisch Meteorologisches Observatorium Davos), d'ACRIM (ACtive Radiometer Irradiance Monitor) et du IRMB (Institut Royal Météorologique de Belgique), ne sont pas en accord entre eux, en particulier au niveau des minima du cycle d'activité, et le modèle permet seulement de reproduire celui du PMOD avec exactitude lorsque la composante variable à long terme est proportionnelle au flux radio à 10.7 cm. Toutefois, en utilisant des polynômes de Lagrange pour représenter la variation du Soleil inactif, l'accord est amélioré pour les trois composites durant les minima, bien que les relations entre le niveau minimal de l'irradiance et la longueur du cycle précédent varient d'un cas à l'autre. Les résultats obtenus avec le modèle d'irradiance spectrale ont été utilisés dans une étude d'intercomparaison de la réponse de la photochimie stratosphérique à différentes représentations du spectre solaire. Les simulations en mode transitoire d'une durée de 10 jours ont été effectuées avec un spectre solaire constant correspondant soit à une période d'activité minimale ou à une période d'activité maximale. Ceci a permis d'évaluer la réponse de la concentration d'ozone à la variabilité solaire au cours d'un cycle et la différence entre deux minima. En plus de ceux de MOCASSIM, les spectres produits par deux modèles ont été utilisés (NRLSSI et MGNM) ainsi que les données de SIM et SOLSTICE/SORCE. La variabilité spectrale de chacun a été extraite et multipliée à un spectre de base représentant le minimum d'activité afin de simuler le spectre au maximum d'activité. Cela a été effectué dans le but d'isoler l'effet de la variabilité seule et d'exclure celui de la valeur absolue du spectre. La variabilité spectrale d'amplitude relativement élevée des observations de SORCE n'a pas provoqué l'inversion de la réponse de l'ozone à hautes altitudes obtenues par d'autres études, ce qui peut être expliqué par la nature même du modèle utilisé ainsi que par sa limite supérieure en altitude. Finalement, la réponse de l'ozone semble être à peu près proportionnelle à la variabilité de l'intégrale du flux pour lambda<241 nm. La comparaison des concentrations d'ozone obtenues avec les spectres originaux au minimum d'activité démontre que leur différence est du même ordre de grandeur que la variabilité entre le minimum et le maximum d'un cycle typique. Le problème du choix de la reconstruction de l'irradiance à utiliser pour les simulations climatiques dans le passé demeure non résolu.

Migration and Spatial Development

This is an empirical study with theoretical interpretation and elaboration simultaneously on the migration process and the related spatial development in contemporary China. In so doing, there is always a combination of series of studies of the modernization of the migrants themselves with accumulation of forms of capital and changes of lebenswelt (life world) as well as the regions of their origins by the effective use of the gained resources from outgoing migration and remigration. With great efforts made to put the issues together for analysis, the author has taken three approaches to the study based on the political and economic institutional arrangements, the field work data and the elaboration of respective findings. First, as the analytical parts of the institutional changes, which have gone through the whole research, many of the policies from state level to townships involved in the migration, remigration and spatial development have been interpreted with Chinese political and cultural insight. The making of these, as the means of understanding the contexts of macro level and micro level cases is served as key linkages between scholarly imagination and social reality. Indeed most of the discussions made to explain the phenomena such as the sudden upsurge of migration flows, the emergence of three generations, the strong and weak trends of remigration as well as the related spatial development planning, etc are mainly due to the domination, at least the impact of governments decision-making in spite of growing market functioning in often operative manners. Secondly, case studies of the effects of migration and remigration are carried out between the years of 1995 and 2005 in the costal urban regions as designations and the interior rural regions as origins. Conducted mainly by the author, the cases drawn in the research focus on the process of migration with an accumulation of forms of capital away from home and the effective use of the resources flowing back to home areas. As a result, ways of accumulation and utilization of the economic, social and cultural capital are described and interpreted in terms of the development and modernization of both the migrants themselves and the regions where they come out from or move to in the future. Thirdly, in accordance with the findings generated from the cases, the author proposes in the final chapter an important argumentation as conclusion that the duel social-economic structure will inevitably be broken up and reformulated with flows of migrants and forms of capital they possess as types of future spatial development that will be put into practice. With scenarios and all the other conclusions worked out in the end, the research concludes that the pluralistic spatial development in the condition of constant space flows between regions can be a decisive line of thinking in the process of urbanization, industrialization and modernization in the long run in the future. Since this is an exploratory study of the past and present, the author has left some space open for academic debates and put forward suggestions on the inclusion of future research before implementing policies necessary for migration associated spatial practice and development.

Diseño de un plan de mejoramiento para el sector panelero en el municipio de Santana - Boyacá

El siguiente trabajo de grado se desarrolla para el sector panelero en el municipio de Santana – Boyacá, ubicado en la Hoya del Río Suárez, lugar en donde la producción de panela constituye la actividad económica más importante de la región. El objetivo del trabajo es la formulación de una estrategia que permita el fortalecimiento de dicho sector, de tal manera que se pueda mejorar la situación actual del mismo. A lo largo del estudio se analizan diferentes factores que recaen en la situación actual del sector; después de utilizar las herramientas del Modelo Matricial y realizar diversas encuestas a paneleros y consumidores, se plantea y evalúa la alternativa que conlleve a la implementación de formas de cooperativismo como solución. Se define el cooperativismo como oportunidad de mejora, ya que por medio del trabajo en equipo y la consolidación de esfuerzos se conseguirían grandes beneficios para el sector; tales como: reconocimiento de marca, mejores condiciones laborales, estabilidad en precios y grandes oportunidades de innovación. La solución propuesta de unificar productores paneleros se compone del establecimiento de un fondo panelero, encargado de mantener precios estándar para los productores y protegerlos de la volatilidad que los caracteriza. La cooperativa organizaría a los productores, además de asegurar la comercialización e incentivar el consumo de panela en el municipio de Santana-Boyacá.

Iron Uptake and Homeostasis in Microorganisms

Preface. Iron is considered to be a minor element employed, in a variety of forms, by nearly all living organisms. In some cases, it is utilised in large quantities, for instance for the formation of magnetosomes within magnetotactic bacteria or during use of iron as a respiratory donor or acceptor by iron oxidising or reducing bacteria. However, in most cases the role of iron is restricted to its use as a cofactor or prosthetic group assisting the biological activity of many different types of protein. The key metabolic processes that are dependent on iron as a cofactor are numerous; they include respiration, light harvesting, nitrogen fixation, the Krebs cycle, redox stress resistance, amino acid synthesis and oxygen transport. Indeed, it is clear that Life in its current form would be impossible in the absence of iron. One of the main reasons for the reliance of Life upon this metal is the ability of iron to exist in multiple redox states, in particular the relatively stable ferrous (Fe2+) and ferric (Fe3+) forms. The availability of these stable oxidation states allows iron to engage in redox reactions over a wide range of midpoint potentials, depending on the coordination environment, making it an extremely adaptable mediator of electron exchange processes. Iron is also one of the most common elements within the Earth’s crust (5% abundance) and thus is considered to have been readily available when Life evolved on our early, anaerobic planet. However, as oxygen accumulated (the ‘Great oxidation event’) within the atmosphere some 2.4 billion years ago, and as the oceans became less acidic, the iron within primordial oceans was converted from its soluble reduced form to its weakly-soluble oxidised ferric form, which precipitated (~1.8 billion years ago) to form the ‘banded iron formations’ (BIFs) observed today in Precambrian sedimentary rocks around the world. These BIFs provide a geological record marking a transition point away from the ancient anaerobic world towards modern aerobic Earth. They also indicate a period over which the bio-availability of iron shifted from abundance to limitation, a condition that extends to the modern day. Thus, it is considered likely that the vast majority of extant organisms face the common problem of securing sufficient iron from their environment – a problem that Life on Earth has had to cope with for some 2 billion years. This struggle for iron is exemplified by the competition for this metal amongst co-habiting microorganisms who resort to stealing (pirating) each others iron supplies! The reliance of micro-organisms upon iron can be disadvantageous to them, and to our innate immune system it represents a chink in the microbial armour, offering an opportunity that can be exploited to ward off pathogenic invaders. In order to infect body tissues and cause disease, pathogens must secure all their iron from the host. To fight such infections, the host specifically withdraws available iron through the action of various iron depleting processes (e.g. the release of lactoferrin and lipocalin-2) – this represents an important strategy in our defence against disease. However, pathogens are frequently able to deploy iron acquisition systems that target host iron sources such as transferrin, lactoferrin and hemoproteins, and thus counteract the iron-withdrawal approaches of the host. Inactivation of such host-targeting iron-uptake systems often attenuates the pathogenicity of the invading microbe, illustrating the importance of ‘the battle for iron’ in the infection process. The role of iron sequestration systems in facilitating microbial infections has been a major driving force in research aimed at unravelling the complexities of microbial iron transport processes. But also, the intricacy of such systems offers a challenge that stimulates the curiosity. One such challenge is to understand how balanced levels of free iron within the cytosol are achieved in a way that avoids toxicity whilst providing sufficient levels for metabolic purposes – this is a requirement that all organisms have to meet. Although the systems involved in achieving this balance can be highly variable amongst different microorganisms, the overall strategy is common. On a coarse level, the homeostatic control of cellular iron is maintained through strict control of the uptake, storage and utilisation of available iron, and is co-ordinated by integrated iron-regulatory networks. However, much yet remains to be discovered concerning the fine details of these different iron regulatory processes. As already indicated, perhaps the most difficult task in maintaining iron homeostasis is simply the procurement of sufficient iron from external sources. The importance of this problem is demonstrated by the plethora of distinct iron transporters often found within a single bacterium, each targeting different forms (complex or redox state) of iron or a different environmental condition. Thus, microbes devote considerable cellular resource to securing iron from their surroundings, reflecting how successful acquisition of iron can be crucial in the competition for survival. The aim of this book is provide the reader with an overview of iron transport processes within a range of microorganisms and to provide an indication of how microbial iron levels are controlled. This aim is promoted through the inclusion of expert reviews on several well studied examples that illustrate the current state of play concerning our comprehension of how iron is translocated into the bacterial (or fungal) cell and how iron homeostasis is controlled within microbes. The first two chapters (1-2) consider the general properties of microbial iron-chelating compounds (known as ‘siderophores’), and the mechanisms used by bacteria to acquire haem and utilise it as an iron source. The following twelve chapters (3-14) focus on specific types of microorganism that are of key interest, covering both an array of pathogens for humans, animals and plants (e.g. species of Bordetella, Shigella, , Erwinia, Vibrio, Aeromonas, Francisella, Campylobacter and Staphylococci, and EHEC) as well as a number of prominent non-pathogens (e.g. the rhizobia, E. coli K-12, Bacteroides spp., cyanobacteria, Bacillus spp. and yeasts). The chapters relay the common themes in microbial iron uptake approaches (e.g. the use of siderophores, TonB-dependent transporters, and ABC transport systems), but also highlight many distinctions (such as use of different types iron regulator and the impact of the presence/absence of a cell wall) in the strategies employed. We hope that those both within and outside the field will find this book useful, stimulating and interesting. We intend that it will provide a source for reference that will assist relevant researchers and provide an entry point for those initiating their studies within this subject. Finally, it is important that we acknowledge and thank wholeheartedly the many contributors who have provided the 14 excellent chapters from which this book is composed. Without their considerable efforts, this book, and the understanding that it relays, would not have been possible. Simon C Andrews and Pierre Cornelis

Wheat glutenin proteins assemble into a nanostructure with unusual structural features

The proteins of wheat have a known propensity to aggregate into a variety of forms. We report here a novel nanostructure from wheat proteins, derived from a crude extract of high molecular weight glutenins. The structure was characterised by a significant thioflavin T (ThT) fluorescence and a fibrillar morphology by transmission electron microscopy (TEM). The ThT fluorescence and TEM data are suggestive of an amyloid structure, but the X-ray fibre diffraction data show a reflection pattern (4.02, 4.2-4.3, 4.6, 12.9,19.3 and 38.7 angstrom) inconsistent with both the classic amyloid form and the previously described beta-helix structure. The 4.6 angstrom reflection is consistent with that predicted for the amyloid inter-beta-strand, and the absence of the inter-beta-sheet distance at approximate to 10-11 angstrom is not unprecedented in amyloid-like structures. However, our observed X-ray reflection pattern has not been previously reported and suggests a novel wheat glutenin nanostructure. (C) 2008 Elsevier Ltd. All rights reserved.

Human-machine symbiosis overview

The interface between humans and technology is a rapidly changing field. In particular as technological methods have improved dramatically so interaction has become possible that could only be speculated about even a decade earlier. This interaction can though take on a wide range of forms. Indeed standard buttons and dials with televisual feedback are perhaps a common example. But now virtual reality systems, wearable computers and most of all, implant technology are throwing up a completely new concept, namely a symbiosis of human and machine. No longer is it sensible simply to consider how a human interacts with a machine, but rather how the human-machine symbiotic combination interacts with the outside world. In this paper we take a look at some of the recent approaches, putting implant technology in context. We also consider some specific practical examples which may well alter the way we look at this symbiosis in the future. The main area of interest as far as symbiotic studies are concerned is clearly the use of implant technology, particularly where a connection is made between technology and the human brain and/or nervous system. Often pilot tests and experimentation has been carried out apriori to investigate the eventual possibilities before human subjects are themselves involved. Some of the more pertinent animal studies are discussed briefly here. The paper however concentrates on human experimentation, in particular that carried out by the authors themselves, firstly to indicate what possibilities exist as of now with available technology, but perhaps more importantly to also show what might be possible with such technology in the future and how this may well have extensive social effects. The driving force behind the integration of technology with humans on a neural level has historically been to restore lost functionality in individuals who have suffered neurological trauma such as spinal cord damage, or who suffer from a debilitating disease such as lateral amyotrophic sclerosis. Very few would argue against the development of implants to enable such people to control their environment, or some aspect of their own body functions. Indeed this technology in the short term has applications for amelioration of symptoms for the physically impaired, such as alternative senses being bestowed on a blind or deaf individual. However the issue becomes distinctly more complex when it is proposed that such technology be used on those with no medical need, but instead who wish to enhance and augment their own bodies, particularly in terms of their mental attributes. These issues are discussed here in the light of practical experimental test results and their ethical consequences.

Immersive co-operative psychological virtual environments (ICPVE)

Virtual Reality (VR) has been used in a variety of forms to assist in the treatment of a wide range of psychological illness. VR can also fulfil the need that psychologists have for safe environments in which to conduct experiments. Currently the main barrier against using this technology is the complexity in developing applications. This paper presents two different co-operative psychological applications which have been developed using a single framework. These applications require different levels of co-operation between the users and clients, ranging from full psychologist involvement to their minimal intervention. This paper will also discuss our approach to developing these different environments and our experiences to date in utilising these environments.

Alverata: Latin, Greek and Cyrillic typeface

Alverata: a typeface design for Europe This typeface is a response to the extraordinarily diverse forms of letters of the Latin alphabet in manuscripts and inscriptions in the Romanesque period (c. 1000–1200). While the Romanesque did provide inspiration for architectural lettering in the nineteenth century, these letterforms have not until now been systematically considered and redrawn as a working typeface. The defining characteristic of the Romanesque letterform is variety: within an individual inscription or written text, letters such as A, C, E and G might appear with different forms at each appearance. Some of these forms relate to earlier Roman inscriptional forms and are therefore familiar to us, but others are highly geometric and resemble insular and uncial forms. The research underlying the typeface involved the collection of a large number of references for lettering of this period, from library research and direct on-site ivestigation. This investigation traced the wide dispersal of the Romanesque lettering tradition across the whole of Europe. The variety of letter widths and weights encountered, as well as variant shapes for individual letters, offered both direct models and stylistic inspiration for the characters and for the widths and weight variants of the typeface. The ability of the OpenType format to handle multiple stylistic variants of any one character has been exploited to reflect the multiplicity of forms available to stonecutters and scribes of the period. To make a typeface that functions in a contemporary environment, a lower case has been added, and formal and informal variants supported. The pan-European nature of the Romanesque design tradition has inspired an pan-European approach to the character set of the typeface, allowing for text composition in all European languages, and the typeface has been extended into Greek and Cyrillic, so that the broadest representation of European languages can be achieved.

Backtracks: a devised performance

Backtracks aimed to investigate critical relationships between audio-visual technologies and live performance, emphasising technologies producing sound, contrasted with non-amplified bodily sound. Drawing on methodologies for studying avant garde theatre, live performance and the performing body, it was informed by work in critical and cultural theory by, for example, Steven Connor and Jonathan Rée, on the body's experience and interpretation of sound. The performance explored how shifting national boundaries, mobile workforces, complex family relationships, cultural pluralities and possibilities for bodily transformation have compelled a re-evaluation of what it means to feel 'at home' in modernity. Using montages of live and mediated images, disrupted narratives and sound, it evoked destablised identities which characterise contemporary lived experience, and enacted the displacement of certainties provided by family and nation, community and locality, body and selfhood. Homer's Odyssey framed the performance: elements could be traced in the mise-en-scène; in the physical presence of Athene, the narrator and Penelope weaving mementoes from the past into her loom; and in voice-overs from Homer's work. The performance drew on personal experiences and improvisations, structured around notions of journey. It presented incomplete narratives, memories, repressed anxieties and dreams through different combinations of sounds, music, mediated images, movement, voice and bodily sound. The theme of travel was intensified by performers carrying suitcases and umbrellas, by soundtracks incorporating travel effects, and by the distorted video images of forms of transport playing across 'screens' which proliferated across the space (sails, umbrellas, the loom, actors' bodies). The performance experimented with giving sound and silence performative dimensions, including presenting sound in visual and imagistic ways, for example by using signs from deaf sign language. Through-composed soundtracks of live and recorded song, music, voice-over, and noise exploited the viscerality of sound and disrupted cognitive interpretation by phenomenological, somatic experience, thereby displacing the impulse for closure/destination/home.

Realism and reality formats

The chapter focuses on the relationships between 'Reality TV' and other ‘realist’ forms and genres of television. This issue is connected to larger debates about ‘televisuality’, and the understanding of the distinctiveness of the medium. Television processes and worries over reality in all of its genres, so that realism becomes a particularly ambiguous term. One meaning focuses on the actual scenes, places and people are represented rather than imagined. A second meaning refers to television’s representation of recognisable and often contemporary experience. Another meaning of realism refers to the development of new and different forms to give access to the real. Furthermore, the establishment of category distinctions in television, such as between factual and fictional forms, or between drama and documentary, could be seen as increasingly problematic in contemporary television. Reality TV can thought of as the trying-out of forms and modes of address in one genre or form that are adopted from apparently different genres and forms, thus creating connection and distinction simultaneously. This chapter addresses these distinctions and ambiguities within Reality TV, using examples including One Born Every Minute and The Only Way is Essex.

Nowhere

Nowhere is part on the series notebook architecture. The painting works with a language of forms to construct rather than represent architectural space. What the painting seeks to construct is a dialogue on depth wherein painting is conceived as quasi phenomenological project.

‘I like playing on my trampoline; it makes me feel alive’ valuing physical activity: perceptions and meanings for children and implications for primary schools

This study investigated perceptions that children aged 6–10 years (n = 83) have of what it means to be physically active. Ideographic research was conducted utilising drawings and interviews to understand values that are placed on participating in physical activity (PA). The article questions the idea that whilst it may be commonly accepted by academics that there is a need to be active for health, little research has considered what this may actually mean for the child. Drawing on Bourdieu, the article utilises key concepts within the analysis of ‘capital' to frame an understanding of how children experience PA. Findings suggest that central to children's experiences is the place of social interaction and reciprocation. The article investigated the production and transference of forms of capital: physical, cultural and social. The potential for such concepts to be exploited by schools is discussed with reference to physical education and opportunities offered during free play.

The Stephen Dwoskin dossier: introduction

This dossier aims to consider the contribution Stephen Dwoskin and his work made to the development of film and its infrastructure in the UK from 1964 when he arrived in the London until his death in 2012. Dwoskin not only straddled different contexts and ideologies about film but advocated for the support of work in a wide variety of forms. Because of this he was not easily categorizeable. Much of the work analyzing his camera work and his contribution to film is written in French and there is little, particularly in recent years, in English. As such this dossier constituted an important contribution to the reassessment of a singular avant-garde artist and film maker. (can I use avant garde here?) In the light of his recent death this is a timely moment for a consideration of Dwoskin’s achievements and legacy. As well as having a groundbreaking vision of what film could do, he was an influential figure and constituting force in terms of the milieu and structures that supported the independent film world in the UK for several decades. Much of the literature surrounding this world in the UK has been formed by key figures making sense of their part in history. This dossier aims towards some first steps in historicising his legacy. Two of the proposed texts will be making use of new material to conduct original research made available through the recently acquired Dwoskin Archive at University of Reading. Due to Dowksin’s heterogenous involvement in film, there are many ways in which Dwoskin can be considered and the proposed essays will take a range of perspectives to assess and analyse his contribution.
