Home: the foundations of belonging

To be at home means to be embedded in a dense pattern of relationships to people and place which gives rise to an inherently meaningful experience of the world. This order is neither abstract nor imposed from without, but crystallises from the shared experience of people inhabiting a concrete location. Home involves the localisation of meaning in a concrete setting and in the activities of everyday life, and this embodies an ongoing process of ‘cosmicisation’ which is vital for both social life and individual well-being. Home is not a fixed structure, static and frozen, which shuts out the external world; it is a dynamic centre which draws in experience and gives it meaning. It is a constellation of significance rather than a singular and unitary essence. It is produced by localising processes, which work to concentrate and stabilise value around a secure centre. The elaboration of seven interlinked localising processes forms the core of the thesis: The cultivation of place The accumulation of collective memory The crystallisation of life-ways and their evolution into tradition The generation of mutuality of being through sharing in fundamental biological processes which generate and preserve life Social circles of gift exchange and recognition which reinforce this mutuality of being The elaboration of symbolic boundaries The counterparts of localising processes are globalising ones. These involve the dismantling of the taken-for-granted relationships of everyday life and their reconstitution within spatially extended networks, governed by rationalised institutions, within separate spheres of economic production, commercial transactions, political administration and cultural exchange. The global market, the public arena, technological development and the bureaucratic state are all solvents of localised associations, which result in the dissipation and relativisation of value. However globalising processes never entirely displace localising ones. Even today, localising processes shape those areas of our lives which anchor our identities and provide a sense of meaning: the everyday interactions of home, family, community and intimate circles of friendship.

El concepto de ciudadanía en la obra de Dominique Schnapper: entre el tipo ideal sociológico y el ideal de sociedad democrática

Este artículo analiza la evolución del concepto de ciudadanía en la obra de Dominique Schnapper como uno de los ejemplos más destacados en la sociología contemporánea de una aproximación completa a la cuestión. A través de un recorrido exhaustivo por su obra, el objetivo es profundizar en la comprensión de la tensión entre la dinámica democrática y la idea de ciudadanía en cuanto que tipo ideal del vínculo social y como principio regulador de las sociedades democráticas. La autora propone en sus primeros trabajos una noción de ciudadanía vinculada al proceso político de construcción de la nación que no distingue entre la definición de un tipo ideal sociológico y la construcción de un ideal de sociedad. Esta confusión se corrige al introducir posteriormente en el análisis la incidencia de la democracia sobre las experiencias individuales de la ciudadanía, aportando una perspectiva de análisis de gran utilidad tanto para la comprensión de la dinámica contemporánea de las sociedades democráticas como para la necesaria defensa de la ciudadanía como vínculo social fundamental y como principio fundador de la legitimidad política.

Unraveling networked learning initiatives: an analytic framework

Networked learning happens naturally within the social systems of which we are all part. However, in certain circumstances individuals may want to actively take initiative to initiate interaction with others they are not yet regularly in exchange with. This may be the case when external influences and societal changes require innovation of existing practices. This paper proposes a framework with relevant dimensions providing insight into precipitated characteristics of designed as well as ‘fostered or grown’ networked learning initiatives. Networked learning initiatives are characterized as “goal-directed, interest-, or needs based activities of a group of (at least three) individuals that initiate interaction across the boundaries of their regular social systems”. The proposed framework is based on two existing research traditions, namely 'networked learning' and 'learning networks', comparing, integrating and building upon knowledge from both perspectives. We uncover some interesting differences between definitions, but also similarities in the way they describe what ‘networked’ means and how learning is conceptualized. We think it is productive to combine both research perspectives, since they both study the process of learning in networks extensively, albeit from different points of view, and their combination can provide valuable insights in networked learning initiatives. We uncover important features of networked learning initiatives, characterize actors and connections of which they are comprised and conditions which facilitate and support them. The resulting framework could be used both for analytic purposes and (partly) as a design framework. In this framework it is acknowledged that not all successful networks have the same characteristics: there is no standard ‘constellation’ of people, roles, rules, tools and artefacts, although there are indications that some network structures work better than others. Interactions of individuals can only be designed and fostered till a certain degree: the type of network and its ‘growth’ (e.g. in terms of the quantity of people involved, or the quality and relevance of co-created concepts, ideas, artefacts and solutions to its ‘inhabitants’) is in the hand of the people involved. Therefore, the framework consists of dimensions on a sliding scale. It introduces a structured and analytic way to look at the precipitation of networked learning initiatives: learning networks. Successive research on the application of this framework and feedback from the networked learning community is needed to further validate it’s usability and value to both research as well as practice.

Shame, Dissociation, and Complex PTSD Symptoms in Traumatized Psychiatric and Control Groups: Direct and Indirect Associations With Relationship Distress

Objectives: Elevated shame and dissociation are common in dissociative identity disorder (DID) and chronic posttraumatic stress disorder (PTSD) and are part of the constellation of symptoms defined as complex PTSD. Previous work examined the relationship between shame, dissociation, and complex PTSD and whether they are associated with intimate relationship anxiety, relationship depression, and fear of relationships. This study investigated these variables in traumatized clinical samples and a nonclinical community group.

Method: Participants were drawn from the DID (n = 20), conflict-related chronic PTSD (n = 65), and nonclinical (n = 125) populations and completed questionnaires assessing the variables of interest. A model examining the direct impact of shame and dissociation on relationship functioning, and their indirect effect via complex PTSD symptoms, was tested through path analysis.

Results: The DID sample reported significantly higher dissociation, shame, complex PTSD symptom severity, relationship anxiety, relationship depression, and fear of relationships than the other two samples. Support was found for the proposed model, with shame directly affecting relationship anxiety and fear of relationships, and pathological dissociation directly affecting relationship anxiety and relationship depression. The indirect effect of shame and dissociation via complex PTSD symptom severity was evident on all relationship variables.

Conclusion: Shame and pathological dissociation are important for not only the effect they have on the development of other complex PTSD symptoms, but also their direct and indirect effects on distress associated with relationships.

Value creation in a reregulated market : Divestments, firms and dynamic processes

This thesis makes use of the unique reregulation of pharmaceutical monopoly in Sweden to critically examine intraindustry firm heterogeneity. It contributes to existing divestiture research as it studies the dynamism in between reconfigurations of value constellations and its effects on value creation of divested pharmacies. Because the findings showed that the predominant theory of intraindustry firm heterogeneity could not explain firm performance, the value constellation concept was applied as it captured the phenomena. A patterned finding informed how reconfigurations of value constellations in a reregulated market characterized by strict rules, regulations, and high competition did not generate additional value for firms on short term. My study unveils that value creation is hampered in situations where rules and regulations significantly affect firms’ ability to reconfigure their value constellations. The key practical implication is an alternative perspective on fundamental aspects of the reregulation and how policy-makers may impede firm performance and the intended creation of new value for not only firms but for society as a whole.

Étude de variations génétiques et épigénétiques de gènes candidats des complications métaboliques de l'obésité

L’obésité est de nos jours un problème croissant à travers le monde. La morbidité qui y est associée est surtout reliée au développement des différentes composantes du syndrome métabolique (SMet), une constellation de facteurs de risque regroupant l’hypertension, la dyslipidémie (concentration faible de cholestérol des lipoprotéines à haute densité (C-HDL) et élevée de triglycérides (TG)), l’hyperglycémie et l’obésité. Cependant, certains sujets obèses demeurent métaboliquement sains. Les facteurs génétiques joueraient donc un rôle important dans le développement de l’obésité et de ses complications. Les facteurs épigénétiques semblent également y avoir des effets. L’analyse de tissu adipeux viscéral (TAV) a donc été réalisée pour mener à la découverte de plusieurs gènes différentiellement exprimés et méthylés entre les obèses atteints et non atteints par le SMet. Les deux gènes candidats NMT1 et DGKZ font partie de ce groupe et leurs associations avec les composantes du SMet ont été testées. Leurs niveaux de méthylation et d’expression génique ont aussi été analysés.

Exact Solution of Bayes and Minimax Change-Detection Problems

The challenge of detecting a change in the distribution of data is a sequential decision problem that is relevant to many engineering solutions, including quality control and machine and process monitoring. This dissertation develops techniques for exact solution of change-detection problems with discrete time and discrete observations. Change-detection problems are classified as Bayes or minimax based on the availability of information on the change-time distribution. A Bayes optimal solution uses prior information about the distribution of the change time to minimize the expected cost, whereas a minimax optimal solution minimizes the cost under the worst-case change-time distribution. Both types of problems are addressed. The most important result of the dissertation is the development of a polynomial-time algorithm for the solution of important classes of Markov Bayes change-detection problems. Existing techniques for epsilon-exact solution of partially observable Markov decision processes have complexity exponential in the number of observation symbols. A new algorithm, called constellation induction, exploits the concavity and Lipschitz continuity of the value function, and has complexity polynomial in the number of observation symbols. It is shown that change-detection problems with a geometric change-time distribution and identically- and independently-distributed observations before and after the change are solvable in polynomial time. Also, change-detection problems on hidden Markov models with a fixed number of recurrent states are solvable in polynomial time. A detailed implementation and analysis of the constellation-induction algorithm are provided. Exact solution methods are also established for several types of minimax change-detection problems. Finite-horizon problems with arbitrary observation distributions are modeled as extensive-form games and solved using linear programs. Infinite-horizon problems with linear penalty for detection delay and identically- and independently-distributed observations can be solved in polynomial time via epsilon-optimal parameterization of a cumulative-sum procedure. Finally, the properties of policies for change-detection problems are described and analyzed. Simple classes of formal languages are shown to be sufficient for epsilon-exact solution of change-detection problems, and methods for finding minimally sized policy representations are described.

Use of satellite observations for operational oceanography: recent achievements and future prospects

The paper gives an overview of the development of satellite oceanography over the past five years focusing on the most relevant issues for operational oceanography. Satellites provide key essential variables to constrain ocean models and/or serve downstream applications. New and improved satellite data sets have been developed and have directly improved the quality of operational products. The status of the satellite constellation for the last five years was, however, not optimal. Review of future missions shows clear progress and new research and development missions with a potentially large impact for operational oceanography should be demonstrated. Improvement of data assimilation techniques and developing synergetic use of high resolution satellite observations are important future priorities.

A rehabilitation intervention to promote physical recovery following intensive care: a detailed description of construct development, rationale and content together with proposed taxonomy to capture processes in a randomised controlled trial.

Background: increasing numbers of patients are surviving critical illness, but survival may be associated with a constellation of physical and psychological sequelae that can cause on going disability and reduced health-related quality of life. Limited evidence currently exists to guide the optimum structure, timing, and content of rehabilitation programmes. There is a need to both develop and evaluate interventions to support and expedite recovery during the post-ICU discharge period. This paper describes the construct development for a complex rehabilitation intervention intended to promote physical recovery following critical illness. The intervention is currently being evaluated in a randomised trial (ISRCTN09412438; funder Chief Scientists Office, Scotland). Methods: the intervention was developed using the Medical Research Council (MRC) framework for developing complex healthcare interventions. We ensured representation from a wide variety of stakeholders including content experts from multiple specialties, methodologists, and patient representation. The intervention construct was initially based on literature review, local observational and audit work, qualitative studies with ICU survivors, and brainstorming activities. Iterative refinement was aided by the publication of a National Institute for Health and Care Excellence guideline (No. 83), publicly available patient stories (Healthtalkonline), a stakeholder event in collaboration with the James Lind Alliance, and local piloting. Modelling and further work involved a feasibility trial and development of a novel generic rehabilitation assistant (GRA) role. Several rounds of external peer review during successive funding applications also contributed to development. Results: the final construct for the complex intervention involved a dedicated GRA trained to pre-defined competencies across multiple rehabilitation domains (physiotherapy, dietetics, occupational therapy, and speech/language therapy), with specific training in post-critical illness issues. The intervention was from ICU discharge to 3 months post-discharge, including inpatient and post-hospital discharge elements. Clear strategies to provide information to patients/families were included. A detailed taxonomy was developed to define and describe the processes undertaken, and capture them during the trial. The detailed process measure description, together with a range of patient, health service, and economic outcomes were successfully mapped on to the modified CONSORT recommendations for reporting non-pharmacologic trial interventions. Conclusions: the MRC complex intervention framework was an effective guide to developing a novel post-ICU rehabilitation intervention. Combining a clearly defined new healthcare role with a detailed taxonomy of process and activity enabled the intervention to be clearly described for the purpose of trial delivery and reporting. These data will be useful when interpreting the results of the randomised trial, will increase internal and external trial validity, and help others implement the intervention if the intervention proves clinically and cost effective.

A noise simulator for eLISA: Migrating LISA Pathfinder knowledge to the eLISA mission

We present a new technical simulator for the eLISA mission, based on state space modeling techniques and developed in MATLAB. This simulator computes the coordinate and velocity over time of each body involved in the constellation, i.e. the spacecraft and its test masses, taking into account the different disturbances and actuations. This allows studying the contribution of instrumental noises and system imperfections on the residual acceleration applied on the TMs, the latter reflecting the performance of the achieved free-fall along the sensitive axis. A preliminary version of the results is presented.

El climatismo

En la actualidad, el lenguaje dominante en que se expresa la conciencia ecológica o ambiental gira alrededor del cambio climático antropogénico. La política de la ecología hoy día es la política del climatismo. El climatismo refleja, en primer lugar, la evolución de los discursos ambientales desde su aparición hasta el cambio de siglo y la nueva constelación política. En segundo lugar, encarna una configuración específica de actores y discursos en forma de un sentido común dominante a la hora de pensar la relación sociedad-medio natural, que generan un efecto de maquillaje verde, de pánico, de homogeneización métrica carbónica, y de sujeción estatal bajo el régimen Kioto. Todos estos efectos ayudan a crear o enmascarar inequidades. Tomar en cuenta ciertas visiones alternativas del régimen climático global puede ayudar a corregir estos efectos.

Primary fallopian tube carcinoma: review of MR imaging findings

Objectives To review the epidemiological and clinical features of primary fallopian tube carcinoma (PFTC), and to illustrate the spectrum of MRI findings, with pathological confirmation. Methods This article reviews the relevant literature on the epidemiological, clinical, and imaging features of primary fallopian tube carcinoma, with pathological confirmation, using illustrations from the authors’ teaching files. Results Primary fallopian tube carcinoma came under focus over the last few years due to its possible role on the pathogenesis of high-grade serous epithelial ovarian and peritoneal cancers. Typical symptoms, together with the presence of some of the most characteristic MRI signs, such as a Bsausage-shaped^ pelvic mass, hydrosalpinx, and hydrometra, may signal the presence of primary fallopian cancer, and allow the radiologist to report it as a differential diagnosis. Conclusions Primary fallopian tube carcinoma has a constellation of clinical symptoms and magnetic resonance imaging features, which may be diagnostic. Although these findings are not present together in the majority of cases, radiologists who are aware of them may include the diagnosis of primary fallopian tube cancer in their report more frequently and with more confidence. Teaching Points • PFTC may be more frequent than previously thought • PFTC has specific clinical and MRI characteristics • Knowledge of typical PFTC signs enables its inclusion in the differential diagnosis • PFTC is currently staged under the 2013 FIGO system • PFTC is staged collectively with ovarian and peritoneal neoplasms

L’épave du Machault, 1760 : entre tradition et innovation.

Cette étude s’intéresse à l’industrie de la construction navale pour le milieu du XVIIIe siècle en France dans la région de Bayonne. L’objectif est de documenter la relation qu’entretiennent les pratiques de construction traditionnelles et innovatrices à cette période. L’architecture de la frégate le Machault est au cœur de cette analyse. Construit en 1757 à Bayonne et perdu en 1760, le Machault a été fouillé, documenté et parallèlement récupéré par les archéologues de Parcs Canada entre 1969 et 1972 à Ristigouche dans la baie des Chaleurs, Québec. Cette étude constitue la première analyse architecturale approfondie menée sur ces vestiges. L’analyse est réalisée en trois temps qui correspondent aux trois grandes étapes de la chaine opératoire de la construction du navire. Tout d’abord, il est question d’aborder l’aspect de la foresterie afin de saisir la nature de la ressource forestière mobilisée pour la construction de la frégate. Ensuite, ce mémoire se penche sur la conception architecturale des navires qui renvoie à un aspect plus théorique, car il relève de la façon dont les formes du navire ont été « pensées ». Enfin, la charpenterie est abordée afin de saisir la séquence d’assemblage du navire. Ensemble, ces trois grands aspects dressent un portrait général de la construction navale pour la région de Bayonne au milieu du XVIIIe siècle.
