Investigating the barriers to teaching family physicians' and specialists' collaboration in the training environment: a qualitative study
Marie-Dominique Beaulieu, Louise Samson, Guy Rocher, Marc Rioux, Laurier Boucher, Claudio Del Grande
BMC Medical Education , 2009, DOI: 10.1186/1472-6920-9-31
Abstract: This is a multiple-case study based on Abbott's theory of professions. Programs targeted were family medicine, general psychiatry, radiology, and internal medicine. The content of the programs' objectives was analyzed. Associate deans of postgraduate studies, program directors, educators, and residents were interviewed individually or in focus groups (47 residents and 45 faculty members).The training objectives related to family physicians-specialists collaboration were phrased in very general terms and lacked specificity. Obstacles to effective collaboration were aggregated under themes of professional responsibility and questioned expertise. Both trainees and trainers reported increasing distances between specialty and general medicine in three key fields of the professional system: the workplace arena, the training setting, and the production of academic knowledge.The challenges of developing collaborating skills between generalists and specialist physicians are comparable in many ways to those encountered in inter-professional collaboration and should be given more consideration than they currently receive if we want to improve coordination between primary and specialty care.Interactions between family physicians (Appendix 1) and specialists significantly determine the quality of coordination between primary and specialty care. [1-3] Disruption of this coordination undermines healthcare system efficiency, quality of care, and patient safety.[2,4-6] Medical organizations worldwide have identified improving this collaboration as a priority.[3,7,8] Despite successful local interventions to improve such collaboration, results overall have been mitigated. [9-11]It is during training that professional identity is shaped and professionals have their first collaboration experiences.[12,13] Empirical research exploring how professional collaboration is learned within the medical profession, particularly between family physicians and specialists, is relatively rare.[14] A
Mind, Davidson and Reality
Daniel Laurier
Principia : an International Journal of Epistemology , 2005,
Abstract: The aim of this article is to show that the prospects for intentional irreal-ism are much brighter than it is generally thought. In the first section, I provide a general characterization of some of the various forms that the realism/irrealism debates might take. In the second, I ask whether there is any defensible form of realism about intentional states. I show that most candidates are nearly trivially false, and that the only form of in-tentional realism which is not, is a restricted one which is prima facie no more plausible than the corresponding form of irrealism. In the third and last section, I defend my interpretation of what intentional irrealism amounts to against some possible misunderstandings, give some reasons why it should be taken seriously and argue that it could plausibly be at-tributed to Davidson.
Long-Memory and Spurious Breaks in Ecological Experiments  [PDF]
Thomas R. Boucher
Open Journal of Statistics (OJS) , 2017, DOI: 10.4236/ojs.2017.75054
Abstract: The impact of long-memory on the Before-After-Control-Impact (BACI) design and a commonly used nonparametric alternative, Randomized Intervention Analysis (RIA), is examined. It is shown the corrections used based on short-memory processes are not adequate. Long-memory series are also known to exhibit spurious structural breaks that can be mistakenly attributed to an intervention. Two examples from the literature are used as illustrations.
Comparison of physically- and economically-based CO2-equivalences for methane
O. Boucher
Earth System Dynamics (ESD) & Discussions (ESDD) , 2012, DOI: 10.5194/esd-3-49-2012
Abstract: There is a controversy on the role methane (and other short-lived species) should play in climate mitigation policies, and there is no consensus on what an optimal methane CO2-equivalence should be. We revisit this question by discussing some aspects of physically-based (i.e. global- warming potential or GWP and global temperature change potential or GTP) and socio-economically-based climate metrics. To this effect we use a simplified global damage potential (GDP) that was introduced by earlier authors and investigate the uncertainties in the methane CO2-equivalence that arise from physical and socio-economic factors. The median value of the methane GDP comes out very close to the widely used methane 100-yr GWP because of various compensating effects. However, there is a large spread in possible methane CO2-equivalences from this metric (1–99% interval: 10.0–42.5; 5–95% interval: 12.5–38.0) that is essentially due to the choice in some socio-economic parameters (i.e. the damage cost function and the discount rate). The main factor differentiating the methane 100-yr GTP from the methane 100-yr GWP and the GDP is the fact that the former metric is an end-point metric, whereas the latter are cumulative metrics. There is some rationale for an increase in the methane CO2-equivalence in the future as global warming unfolds, as implied by a convex damage function in the case of the GDP metric. We also show that a methane CO2-equivalence based on a pulse emission is sufficient to inform multi-year climate policies and emissions reductions, as long as there is enough visibility on CO2 prices and CO2-equivalences for the stakeholders.

Abstract: There is a controversy on the role methane (and other short-lived species) should play in climate mitigation policies and no consensus on what an optimal methane CO2-equivalence should be. We revisit this question by discussing the relative merits of physically-based (i.e. Global Warming Potential or GWP and Global Temperature change Potential or GTP) and socio-economically-based climate metrics. To this effect we use a simplified Global Damage Potential (GDP) that was introduced by earlier authors and investigate the uncertainties in the methane CO2-equivalence that arise from physical and socio-economic factors. The median value of the methane GDP comes out very close to the widely used methane 100-year GWP because of various compensating effects. However there is a large spread in possible methane CO2-equivalences (1–99% interval: 10.0–42.5; 5–95% interval: 12.5–38.0) that is essentially due to the choice in some socio-economic parameters (i.e. the damage cost function and the discount rate). The methane 100-year GTP falls outside these ranges. It is legitimate to increase the methane CO2-equivalence in the future as global warming unfolds. While changes in biogeochemical cycles and radiative efficiencies cause some small changes to physically-based metrics, a systematic increase in the methane CO2-equivalence can only be achieved by some ad-hoc shortening of the time horizon. In contrast using a convex damage cost function provides a natural increase in the methane CO2-equivalence for the socio-economically-based metrics. We also show that a methane CO2-equivalence based on a pulse emission is sufficient to inform multi-year climate policies and emissions reductions as long as there is some degree of visibility on CO2 prices and CO2-equivalences.
Portrait d’un policier de la brigade anti-criminalité dans une cité ghetto fran aise Portrait of a policeman of the brigade anti-criminality in a french “city ghetto”

Abstract: Face à l’intensité des violences lors des émeutes urbaines de l’automne 2005, pour prévenir et réprimer d’éventuels nouveaux désordres, l’état a décidé de renforcer la présence des forces de l’ordre en capacité de se confronter à la jeunesse turbulente des quartiers populaires. Des interactions frictionnelles, des rapports paroxystiques et complexes vont alors se développer entre des jeunes figures de désordres et des acteurs institués et émergents d’encadrement des classes populaires, en particulier des policiers chargés de pacifier les cités périphériques ghetto sées. Dans ce contexte, à partir d’une enquête ethnographique dans une cité ségréguée, cet article dresse le portrait sociologique d’un policier de la brigade anti-criminalité (BAC) de nuit. à partir de la description de son travail quotidien, de ses épreuves et de ses modes d’action, de sa relation à la violence, notamment des émeutes urbaines ainsi que des rapports d’hostilité qu’il entretient avec une partie de la population, ce texte montre que l’expérience sociale des policiers en confrontation avec des jeunes turbulents est ambivalente puisqu’ils sont à la fois traqueurs et victimes . In front of the intensity of the violence during the urban riots of the autumn, 2005, to prevent and repress possible new disorders, the State decided to strengthen the presence of the police in capacity to confront with the “turbulent youth” of the popular districts. Frictional interactions, paroxystic and complex reports are then going to develop between young “faces of disorders” and established an emergent social actors of lower classes, in particular policemen asked to pacify the inner cities. In this context, from an ethnographical investigation in a segregated city, this article paints the sociological portrait of a policeman of the brigade anti-criminality (BAC). From the description of his daily work, his tests and his modes of action, his relation with the violence, in particular urban riots as well as reports of hostility which he maintains with a part of the population. This text shows that the social experience of the policemen in confrontation with “turbulent young people” is ambivalent because they are at the same time trackers and victims.
A cosmological test for general relativity

Abstract: The effect of spatial variations of the Newton constant on the cosmic microwave background is studied. Constraints on the strong equivalence principle violation at the recombination time are then obtained with the help of WMAP data and of the standard theory of big-bang nucleosynthesis.
Video Analysis: Lessons from Professional Video Editing Practice Videoanalyse: Was wir vom professionellen Edieren von Videos lernen k nnen Video-análisis: lecciones de la práctica de edición de video profesional

Forum : Qualitative Social Research , 2008,
Abstract: In this paper we join a growing body of studies that learn from vernacular video analysts quite what video analysis as an intelligible course of action might be. Rather than pursuing epistemic questions regarding video as a number of other studies of video analysis have done, our concern here is with the crafts of producing the filmic. As such we examine how audio and video clips are indexed and brought to hand during the logging process, how a first assembly of the film is built at the editing bench and how logics of shot sequencing relate to wider concerns of plotting, genre and so on. In its conclusion we make a number of suggestions about the future directions of studying video and film editors at work. URN: urn:nbn:de:0114-fqs0803378 Dieser Artikel nimmt die These auf, dass wir von Videopraktiker/innen über Videoanalyse als Handlungsverlauf lernen k nnen. Anstatt in eine epistemisch-theoretische Diskussion über Video einzusteigen, wie dies viele Videostudien tun, besch ftigt sich der Artikel mit Film als Handwerk. Wir untersuchen, wie ein professioneller Filmeditor Tonaufnahmen und gedrehte Filmbilder erfasst und codiert, wie am Schneidetisch eine erste zusammenh ngende Einheit eines Filmes entsteht und wie die korrekte Abfolge der Aufnahmen mit Fragen der Handlung, der Spannung oder des Genres verbunden ist. Der Artikel schl gt abschlie end eine Reihe von Themen vor, die für weitere Studien über die praktische Arbeit von Film- und Videoeditor/innen von Interesse sein k nnten. URN: urn:nbn:de:0114-fqs0803378 Este artículo se integra a un creciente corpus de estudios que entiende que el videoánalisis, como secuenciación de la acción, puede aprender de la experiencia de los profesionales de la edición de video. En vez de realizar una reflexión teórico-epistemológica sobre el video, tal como hacen muchos otros estudios, este artículo se ocupa del oficio de la realización de lo fílmico. En este sentido, examinamos cómo un realizador profesional maneja e indexa secuencias de video y audio, cómo se producen las primeras unidades fílmicas en la mesa de edición y cómo las logísticas de secuenciación de tomas están relacionadas con aspectos más amplios relativos a la trama, el género, etc. En las conclusiones hacemos una serie de sugerencias que pueden ser de interés para futuros estudios sobre el trabajo práctico de realizadores de cine y video.

Abstract: The general objective of this study is to identify the specific needs of youths who have suffered a moderate or severe traumatic brain injury (TBI) and their levels of life habit accomplishments. The secondary objective aims to identify how they view themselves in the future with regard to their life habits. Eighteen young persons with moderate or severe TBIs aged 14 to 20 completed questionnaires based on the Life-Habits questionnaire and elaborated on their current level of satisfaction and their visions of the future. Teenagers reported that maintaining good interpersonal relationships, being autonomous, fulfilling their responsibilities, warding off lone-liness, as well as being supported in their efforts to reach a satisfying response to their needs and concerns were their highest priorities. In order to increase their satisfaction related to life habits they suggest improving external factors, such as information concerning TBIs to their entourage. They see themselves as complete social participants in the future. Youths with moderate or severe TBIs identified their needs and envisioned their future to be like that of any other teenager and young adult. They hope to start a family and find a good job. They also identified strategies to improve their life habits.

Abstract: We have developed GridCell as a three-dimensional simulation environment for investigating the behaviour of biochemical networks under a variety of spatial influences including crowding, recruitment and localization. GridCell enables the tracking and characterization of individual particles, leading to insights on the behaviour of low copy number molecules participating in signaling networks. The simulation space is divided into a discrete 3D grid that provides ideal support for particle collisions without distance calculation and particle search. SBML support enables existing networks to be simulated and visualized. The user interface provides intuitive navigation that facilitates insights into species behaviour across spatial and temporal dimensions. We demonstrate the effect of crowing on a Michaelis-Menten system.GridCell is an effective stochastic particle simulator designed to track the progress of individual particles in a three-dimensional space in which spatial influences such as crowding, co-localization and recruitment may be investigated.One of the main goals of computational cell biology aims to accurately simulate large biological systems at molecular resolution. Stochastic effects and spatial constraints are increasingly being recognized as important factors in the normal functioning of molecular networks [1]. The efficiency of biochemical networks is enhanced by component co-localization [2], and certain signaling networks are thought to be facilitated by transport and co-localization [3]. In addition, molecular crowding has been shown to affect biochemical systems [4-6]. Modeling and simulation of these kinds of networks requires new kinds of stochastic simulators.We developed GridCell to simulate biological models with specific consideration for stochasticity, locality, and collision. GridCell is based on a simplified model for molecular movement and interaction. It uses a discrete three-dimensional cubic grid based on the D3Q27 model often used in
