Conclusion : les usages possibles et contestables des normes et des institutions dans l'internationalisation des services

The conclusion of this volume on technical standards in the regulation of services reviews the authors' contributions to understanding the relation between tertiarisation, internationalisation and standardisation from three distinct perspectives : theoretical, institutional, and sectorial. It argues that conventional views on conditions for standardisation and internationalisation of service activities are overly restrictive, making them dependent on sectorial and institutional specificity. In emphasizing the possible and contestable uses of service standards, the volume opens a critical debate on service offshoring, underlining the social and historical constructions of its transnational logic.

Diagnosi de necessitats socials i educatives de l'aula multilingüe: aproximació des del cas de matemàtiques

El nostre objectiu principal ha estat estudiar el desenvolupament de competències discursives de l’alumnat (d’origen) estranger que contribueixin a entendre i atendre les seves necessitats socials i educatives a l’aula (de matemàtiques) multilingüe. Amb aquesta intenció, hem dut a terme accions científiques a dos nivells: amb professorat i amb estudiants. Quant a la caracterització de la complexitat normativa de l’aula de matemàtiques multilingüe, tal com estava previst: 1) hem exemplificat diverses normes socials i lingüístiques existents en el desenvolupament de pràctiques matemàtiques a l’aula; i 2) hem particularitzat el fenomen de la diversitat de normes socials i lingüístiques en casos de sessions de classe de secundària. Quant a la documentació d'indicadors de progrés en la comprensió de normes socials i lingüístiques de l’aula, i en el desenvolupament de competències discursives d’adequació a aquestes normes, tal com estava previst: 1) hem caracteritzat estratègies d’ensenyament i aprenentatge de normes socials i lingüístiques en situacions d’interacció social en petit i gran grup; i 2) hem construït criteris de seguiment del grau de desenvolupament de competències discursives d’adequació a les normes, tant pel que a professorat com alumnat. Finalment, quant a l'anàlisi de la contribució de les competències discursives a la construcció d’identitats socials, lingüístiques i matemàtiques compartides: 1) hem estudiat els usos que l’estudiant (d’origen) estranger fa de normes escolars vinculades a pràctiques socials, lingüístiques i matemàtiques; i 2) hem examinat la construcció de significats socials, lingüístics i matemàtics compartits en un ampli ventall de processos d’adequació a normes de l’aula orquestrades pel professorat de la nostra mostra.

Intégration de méthodes de data mining dans le renseignement criminel : analyse par des structures issues de la théorie des graphes dans le profilage des stupéfiants

Data mining can be defined as the extraction of previously unknown and potentially useful information from large datasets. The main principle is to devise computer programs that run through databases and automatically seek deterministic patterns. It is applied in different fields of application, e.g., remote sensing, biometry, speech recognition, but has seldom been applied to forensic case data. The intrinsic difficulty related to the use of such data lies in its heterogeneity, which comes from the many different sources of information. The aim of this study is to highlight potential uses of pattern recognition that would provide relevant results from a criminal intelligence point of view. The role of data mining within a global crime analysis methodology is to detect all types of structures in a dataset. Once filtered and interpreted, those structures can point to previously unseen criminal activities. The interpretation of patterns for intelligence purposes is the final stage of the process. It allows the researcher to validate the whole methodology and to refine each step if necessary. An application to cutting agents found in illicit drug seizures was performed. A combinatorial approach was done, using the presence and the absence of products. Methods coming from the graph theory field were used to extract patterns in data constituted by links between products and place and date of seizure. A data mining process completed using graphing techniques is called ``graph mining''. Patterns were detected that had to be interpreted and compared with preliminary knowledge to establish their relevancy. The illicit drug profiling process is actually an intelligence process that uses preliminary illicit drug classes to classify new samples. Methods proposed in this study could be used \textit{a priori} to compare structures from preliminary and post-detection patterns. This new knowledge of a repeated structure may provide valuable complementary information to profiling and become a source of intelligence.

Physical activity assessment using a pedometer and its comparison with a questionnaire in a large population survey.

The aim of this study was to evaluate the use of the pedometer in epidemiologic research on physical activity. Within the framework of a health examination survey in 1988-1989, physical activity was assessed in a representative population sample of 493 men and women aged 25-74 years who were residents of Switzerland. They wore a pedometer for 1 week at work and during leisure time, and the results, converted into steps per day, were compared with answers to a questionnaire. The average number of steps per day decreased from 11,900 to 6,700 and from 9,300 to 7,300 for men and women, respectively, in the youngest to the oldest age groups. For men, categorized according to type of physical activity at work, there was a highly significant difference in the number of steps (p < 0.001), whereas in women the results were associated with leisure-time physical activity (p = 0.003). For both sexes, practicing sports more than once a week was associated with an important increase in steps per day. Analyzing the number of steps according to the day of the week and occupational category produced an unexpected result: Men with a physically active job engaged in more leisure-time physical activity on the weekend. The pedometer proved to be useful in assessing physical activity in a large, free-living population.

Data-based approach for developing a physical activity frequency questionnaire.

Measurement of total energy expenditure may be crucial to an understanding of the relation between physical activity and disease and in order to frame public health intervention. To devise a self-administered physical activity frequency questionnaire (PAFQ), the following data-based approach was used. A 24-hour recall was administered to a random sample of 919 adult residents of Geneva, Switzerland. The data obtained were used to establish the list of activities (and their median duration) that contributed to 95% of the energy expended, separately for men and women. Activities that were trivial for the whole sample but that contributed to > or = 10% of an individual's energy expenditure were also selected. The final PAFQ lists 70 activities or group of activities with their typical duration. About 20 minutes are required for respondents to indicate the number of days and the number of hours per day that they performed each activity. The PAFQ method was validated against a heart rate monitor, a more objective method. The total energy estimated by the PAFQ in 41 volunteers correlated well (r = 0.76) with estimates using a heart rate monitor. The authors conclude that the design of their self-administered physical activity frequency questionnaire based on data from 24-hour recall appeared to accurately estimate energy expenditure.

Draft environmental report on Cape Verde

Faced with recurrent drought and famine during five centuries of human occupation, the small and densely populated Cape Verde Islands have a history of severe environmental problems. The arid climate and steep, rocky terrain provide scant resources for traditional subsistance farming under the best conditions, and in years of low rainfall the failure of rainfed crops causes massive food shortages. Agricultural use of steep slopes where rainfall is highest has led to soil erosion, as has removal of the island's vegetation for fuel and livestock. Pressure on the vegetation is particularly severe in dry years. International aid can provide relief from famine, and the introduction of modern agricultural and conservation techniques can improve the land and increase yield, but it is unlikely that Cape Verde can ever be entirely self -sufficient in food. Ultimately, the solution of Cape Verde's economic and environmental problems will probably require the development of productive urban jobs so the population can shift away from the intensive and destructive use of land for subsistance farming. In the meantime, the people of Cape Verde can best be served by instituting fundamental measures to conserve and restore the land so that it can be used to its fullest potential. The primary environmental problems in Cape Verde today are: 1. Soil degradation. Encouraged by brief but heavy rains and steep slopes, soil erosion is made worse by lack of vegetation. Soils are also low in organic matter due to the practice of completely removing crop plants and natural vegetation for food, fuel or livestock feed. 2. Water shortage. Brief and erratic rainfall in combination with rapid runoff makes surface water scarce and difficult to use. Groundwater supplies can be better developed but capabilities are poorly known and the complex nature of the geological substrate makes estimation difficult. Water is the critical limiting factor to the agricultural capability of the islands. 3. Fuel shortage. Demand for fuel is intense and has resulted in the virtual elimination of native vegetation. Fuelwood supplies are becoming more and more scarce and costly. Development of managed fuelwood plantations and alternate energy sources is required. 4. Inappropriate land use. Much of the land now used for raising crops or livestock is too steep or too arid for these purposes, causing erosion and destruction of vegetation. Improving yield in more appropriate areas and encouraging less damaging uses of the remaining marginal lands can help to alleviate this problem.

Comunicar la ciudad desde el paisaje: hacia una teoría del landscape branding

La necesidad de descodificar los significados inherentes al paisaje, la interactuación sociedadpaisaje (comunicación intra e interpersonal) y, más recientemente, los usos de paisaje a modo de aparador territorial mediático en el ámbito, por ejemplo, de la comunicación publicitaria, del citymarketing o del place branding (comunicación masiva), sirven para plantear el estudio de lo que, de algún modo, representa la persuasión del paisaje, la cual incluye claros tintes emocionales y simbólicos y, por tanto, también comunicacionales. El paisaje en su condición de imagen y/o rostro del territorio acumula la esencia del mensaje implícito en el espacio, posicionándose, de este modo, como la gran metáfora comunicativa de la ciudad. En este sentido, el trabajo de comunicación específico con el intangible paisajístico, unido a la reciente explosión de las denominadas geografías emocionales, plantea una teoría del mensaje territorial basada en la unión de las variables geografía, paisaje, emoción y comunicación. Históricamente, de los estudios de paisaje se han ocupado los geógrafos, arquitectos, historiadores, sociólogos o ambientólogos, entre muchos otros, sin embargo, el paisaje se ha mantenido poco explorado desde la perspectiva de la comunicación. En este sentido, es notoria la proliferación de análisis que ponen el acento en el papel que desarrolla el territorio como mediador de procesos de comunicación o en el estudio de procesos de retroalimentación entre la sociedad y sus espacios (cognición y/o percepción). El actual mercadeo identitario con los lugares se concreta en la creciente producción de marcas territoriales, las cuales acumulan, en los últimos tiempos, un importante protagonismo.

Nonagenarians and centenarians in Switzerland, 1860-2001: a demographic analysis.

STUDY OBJECTIVE: To explore the rapid rise of the extremely old population, showing the magnitude of the increase and identifying demographic mechanisms underlying this increase. DESIGN: Demographic analysis using census data, yearly population estimates, and mortality statistics. SETTING: Switzerland 1860-2001. MAIN RESULTS: Indicators suggest a strong increase in the number of nonagenarians and centenarians in Switzerland as compared with other countries. The increase is mostly attributable to the decline in mortality after age 80. This decline started in the 1950s. CONCLUSION: Nonagenarians and centenarians constitute a new population, which became sizeable after 1950 in Switzerland. There is a need to monitor this population with appropriate demographic and epidemiological indicators.

Over the last few decades, the Swiss higher education system has faced important reforms - both concerning its structure and its governance. As with other European countries, one of the most important changes consists of the strengthening of the higher education institutions' research mission through the reinforcement of the role of the National Science Foundation (NSF), which has become increasingly involved in sustaining academic careers. Meanwhile, traditionally and historically, the definition of a faculty member and his or her financial support has come from the higher education institutions (HEI) themselves. This redefinition of power relationships around the funding of academic temporary positions and research activities by the NSF can be analyzed as an attempt to reform the structure of academic careers and the allocation modes of academic positions. Being able to analyze the issue of allocating academic positions within the normative structure of science (Merton, The sociology of science. University of Chicago Press, Chicago, 1973) is a constant concern for those involved in Higher Education Studies. This chapter is an attempt to nurture the debate by questioning, though a quantitative and qualitative research, the tension between the uses of universalist and particularist criteria in the allocation of academic positions. It analyses the possible exclusion process as a consequence of the organization of academic markets and their embeddedness in a wider societal organization.

Action publique concertée et gestion des sports de nature : une ethnographie participative au Conseil général du Bas-Rhin

En France, la décentralisation et la territorialisation de l'action publique ont fait des sports de nature un objet d'action publique légitime en donnant naissance à de nouveaux outils de management public dédiés à la concertation et à la planification des usages de la nature. Nés de l'article 52 de la Loi sur le sport modifiée en 2000, la Commission Départementale des Espaces, Sites et Itinéraires relatifs aux sports de nature (CDESI) et le Plan Départemental des Espaces Sites et Itinéraires relatifs aux sports de nature (PDESI) sont des outils de concertation territoriale dédiés à la gestion publique des sports de nature au niveau départemental. Un enjeu de ce travail tient à l'appréhension des transformations de l'action publique en s'attachant à l'étude des dispositifs de concertation sur les sports de nature. Un deuxième enjeu de ce travail s'attache à mettre en évidence les effets de la concertation en analysant les interactions et les différents modes d'engagements des acteurs au cours de la « chose publique en train de se faire » (Cefaï, 2002). Les acteurs s'engagent non seulement dans la concertation comprise comme une activité sociale faite d'interactions, mais ils s'engagent également dans la concertation en tant que processus d'action publique. Aussi, un autre enjeu de ce travail est d'appréhender les effets de la concertation par une analyse processuelle des engagements (Fillieule, 2004) des acteurs et des organisations. En mobilisant les outils conceptuels de la sociologie interactionniste, de la sociologie pragmatique, ainsi que de la sociologie structuraliste, l'analyse des situations interactionnelles a notamment permis d'identifier les procédures de cadrage et les techniques dramaturgiques mises en oeuvre par les interactants, ainsi que les répertoires argumentatifs mobilisés par ces acteurs pendant l « 'épreuve » de la concertation. Les confrontations des points de vue et les justifications des prises de positions des acteurs peuvent faire évoluer la configuration initiale des jeux d'acteurs même si, pour certains, ces changements ne restent parfois qu'éphémères. Les organisations s'engagent dans la concertation en fonction de la revendication d'une légitimité qui est à comprendre comme une forme militantisme institutionnel s'articulant autour de la valorisation d'une expertise militante, environnementale, institutionnelle, ou encore de leur statut de partenaire institutionnel. In France, decentralization and territorialization of public action have made outdoor sports become an object of public policies justifiable by giving birth to new tools of public management dedicated to the public consultation, the dialogue, and the planning of the uses of the landscapes. Indeed, born of article 52 of the Law on sport modified in 2000, the Departmental committee for Spaces, Sites and Routes relative to natural sports ( CDESI) and the Departmental Plan of Spaces Sites and Routes relative to natural sports ( PDESI) are governance tools dedicated to the public management of outdoor sports for counties. A challenge of this work is to understand the changes of public policy by focusing on the study of mechanisms for consultation on outdoor sports. A second item of this work is to highlight the effects of cooperation by focusing on the analysis of interactions and actor's commitments during the "public thing in the making" (Cefaï, 2002). Actors commit themselves not only in the dialogue included as a social activity made by interactions, but they also take part to the dialogue included as a process of public action. Also, another issue of this work is to understand the effects of consultation by a processual approach of individual commitments (Fillieule, 2004) of actors and organizations. Using the conceptual tools of symbolic interactionism, pragmatic sociology, and structuralist sociology, the analysis of interactional situations has highlighted the framing work and procedures implemented by the interactants, as well as the dramaturgical techniques and argumentative directories which, they mobilize during the "test" of the consultation. Confrontation of viewpoints and justifications of interactants' positions can evolve from their initial configuration sets, even if for some of them these changes are sometimes ephemeral. Organizations involve themselves according to demands of legitimacy which, are to understand as a shape institutional militancy articulating around the valuation of a militant, environmental, institutional expertise, or still around their status of institutional partner.

Notes sobre subjectivitat i experiència

The aim of this paper is to underline the fact that, in most contemporary philosophical debates (and somehow, issues in feminist theory are not an exception), a well-known term is playing an important role: experience. We need a cartography of the uses of experience, if we want to know what we are talking about and also if we intend to analyze and to rethink the last 25 years of ¿women studies¿, ¿gender studies¿ or ¿subaltern studies¿.

Data-driven clustering : new methods and applications

Abstract : This work is concerned with the development and application of novel unsupervised learning methods, having in mind two target applications: the analysis of forensic case data and the classification of remote sensing images. First, a method based on a symbolic optimization of the inter-sample distance measure is proposed to improve the flexibility of spectral clustering algorithms, and applied to the problem of forensic case data. This distance is optimized using a loss function related to the preservation of neighborhood structure between the input space and the space of principal components, and solutions are found using genetic programming. Results are compared to a variety of state-of--the-art clustering algorithms. Subsequently, a new large-scale clustering method based on a joint optimization of feature extraction and classification is proposed and applied to various databases, including two hyperspectral remote sensing images. The algorithm makes uses of a functional model (e.g., a neural network) for clustering which is trained by stochastic gradient descent. Results indicate that such a technique can easily scale to huge databases, can avoid the so-called out-of-sample problem, and can compete with or even outperform existing clustering algorithms on both artificial data and real remote sensing images. This is verified on small databases as well as very large problems. Résumé : Ce travail de recherche porte sur le développement et l'application de méthodes d'apprentissage dites non supervisées. Les applications visées par ces méthodes sont l'analyse de données forensiques et la classification d'images hyperspectrales en télédétection. Dans un premier temps, une méthodologie de classification non supervisée fondée sur l'optimisation symbolique d'une mesure de distance inter-échantillons est proposée. Cette mesure est obtenue en optimisant une fonction de coût reliée à la préservation de la structure de voisinage d'un point entre l'espace des variables initiales et l'espace des composantes principales. Cette méthode est appliquée à l'analyse de données forensiques et comparée à un éventail de méthodes déjà existantes. En second lieu, une méthode fondée sur une optimisation conjointe des tâches de sélection de variables et de classification est implémentée dans un réseau de neurones et appliquée à diverses bases de données, dont deux images hyperspectrales. Le réseau de neurones est entraîné à l'aide d'un algorithme de gradient stochastique, ce qui rend cette technique applicable à des images de très haute résolution. Les résultats de l'application de cette dernière montrent que l'utilisation d'une telle technique permet de classifier de très grandes bases de données sans difficulté et donne des résultats avantageusement comparables aux méthodes existantes.

Secondhand smoke exposure in children is associated with common carotid artery intima-media thickness

Objective: To investigate the association between common carotid artery intima-media thickness (cIMT) and exposure to secondhand smoke (SHS) in children. Methods: Data were available at baseline in the Quebec Adiposity and Lifestyle investigation in Youth (QUALITY) study, an ongoing longitudinal investigation of Caucasian children aged 8e10 years at cohort inception, who had at least one obese parent. Data on exposure to parents, siblings and friends smoking were collected in interviewer-administered child, and self-report parent questionnaires. Blood cotinine was measured with a high sensitivity ELISA. cIMTwas measured by ultrasound. The association between blood cotinine and cIMT was investigated in multivariable linear regression analyses controlling for age, body mass index, and child smoking status. Results: Mean (SD) cIMT (0.5803 (0.04602)) did not differ across age or sex. Overall 26%, 6% and 3% of children were exposed to parents, siblings and friends smoking, respectively. Cotinine ranged from 0.13 ng/ml to 7.38 ng/ml (median (IQR)¼0.18 ng/ml)). Multivariately, a 1 ng/ml increase in cotinine was associated with a 0.090 mm increase in cIMT (p¼0.034). Conclusion: In children as young as age 8e10 years, exposure to SHS relates to cIMT, a marker of pre-clinical atherosclerosis. Given the wide range of health effects of SHS, increased public health efforts are needed to reduced exposure among children in homes an private vehicles.
