Représenter les patrons
Authors: Penissat Étienne , Rabier Marion
Published: September 2015

Résumé Si les enquêtes sur la morphologie sociale des dirigeants politiques, syndicaux, paysans ou associatifs sont un classique de la sociologie de l'action collective, la sociographie des représentants de la cause patronale est presque inexistante. À partir d'un corpus de présidents de fédérations du Medef entre 1978 et 2008 (n = 251), cet article vient combler cette lacune. Ces dirigeants patronaux ne sont pas le miroir du groupe social représenté. La quasi-totalité de leurs caractéristiques sociodémographiques et de leur position professionnelle les distingue nettement des chefs d'entreprise français en les positionnant dans la fraction supérieure du patronat. Proches des grands patrons du CAC 40, ils n'en ont toutefois pas l'ensemble des dispositions : bien qu'importantes, leurs capitaux scolaires sont moins élevées et surtout le pôle « étatique » y est minoritaire. La stabilité dans le temps et l'homogénéité sociale de ce groupe n'en laisse pas moins apparaître quelques clivages, notamment entre un pôle de dirigeants de petites fédérations et un pôle de dirigeants de grandes fédérations plus dotés en capitaux scolaires, symboliques mais également bureaucratiques. La sélection des dirigeants du MEDEF contribue ainsi à assurer la domination d'une fraction supérieure du monde patronal sur les autres.
Feuilleton théâtral à la télévision ou feuilleton télévisé au théâtre ?
Authors: Helbo André
Published: September 2015

Si la radio a largement puisé dans le matériau textuel du théâtre, et si le théâtre a beaucoup exploité la thématique de la voix, l’image télévisuelle manifeste, quant à elle, beaucoup plus de réticence à prendre en charge le spectacle théâtral. Certes, il existe des formes de captation médiatique du théâtre ; on peut relever aussi des traits énonciatifs de théâtralité qui marquent certaines écritures télévisuelles. Cependant, la télévision n’est plus globalement fille du théâtre : la relation s’est inversée. C’est le spectacle vivant qui s’inspire des médias. On peut faire l’hypothèse que le feuilleton constitue un dispositif énonciatif nourricier du théâtre et de la performance d’aujourd’hui. À travers l’examen de nombreuses productions scéniques contemporaines, l’article examine les modalités des alliances « médiaturgiques » du spectacle vivant. Parmi celles-ci, le feuilleton et la série, l’effet de présence, le réel en scène, la crise de la fiction jouent un rôle essentiel.
Le deuil du deuil : transitions critiques, pertes et nouvelles identités du familial
Authors: D’Amore Salvatore
Published: September 2015

Les nouvelles familles sont constamment confrontées à des pertes multiples. Il arrive que dans la consultation psychothérapeutique, ces familles se présentent comme des systèmes « endeuillés », dont la perte constitue un noyau organisateur de leur identité. Les nouvelles théories en matière de deuil se focalisent surtout sur les processus de recherche de sens. Dans le cas des pertes ambiguës, le deuil du deuil implique l’abandon de la vision du deuil comme processus de « détachement progressif » pour se concentrer sur la gestion du stress dû à l’écart entre absence physique des personnes, relations et contextes et leur présence et influence psychologique. Sur la base d’une illustration clinique, cet article essaie de prouver la pertinence de tels concepts. Il suggère de travailler à recréer, à réenvisager et à reconstruire les liens familiaux autour de ses pertes ou de ses séparations. Cependant, ce travail aurait un caractère réducteur s’il ne tenait pas compte des avantages et des gains que les familles ne considèrent et n’anticipent pas dans le cadre de l’expérience des pertes.

Survivre et exister dans le « ne rien faire »
Authors: Gajate Vergés Teresa
Published: September 2015

Dans cet article, l’auteur parle de son parcours psychique à l’intérieur d’une institution psychiatrique avec un fonctionnement assez particulier, et comment, à partir de son vécu personnel, elle a pu comprendre la raison d’être de cette particularité. Dans le dispositif d’accueil et de psychothérapie familiale, les résonances du thérapeute et l’isomorphisme entre institution et familles sont des précieux outils de travail.
Prédicat argumentatif et concept ad hoc
Authors: Kida Kohei
Published: September 2015

La Théorie des Blocs Sémantiques (Carel, 2011a), issue de la théorie de l’argumentation dans la langue (Anscombre et Ducrot, 1983), repose sur un certain nombre de notions nouvelles, l’une des plus importantes d’entre elles étant celle de « prédicat argumentatif », qui désigne l’unique prédicat exprimé par un « enchaînement argumentatif ». Le présent article vise à clarifier la notion de prédicat argumentatif à travers sa confrontation avec celle de « concept ad hoc  » développée dans le cadre de la théorie de la pertinence (Sperber et Wilson, 1986b/95, 1989 ; Carston, 2002a), à laquelle elle semble pouvoir être assimilée à première vue.
Agroécosystèmes innovants : des stocks a préserver aux fonds a concevoir
Authors: Berthet Elsa
Published: September 2015

Gérer les écosystèmes dans un contexte de changement global, tout en respectant leur fonctionnement écologique, soulève de nombreuses difficultés au plan conceptuel comme opérationnel. Deux enjeux majeurs sont l’innovation et la coordination d’acteurs aux intérêts divergents. Or, bien que la gestion des écosystèmes fasse l’objet de nombreuses recherches, celles-ci portent peu sur les processus d’innovation collectifs à l’échelle des territoires. En nous appuyant sur le modèle « fonds-flux » de Georgescu-Roegen, nous modélisons les écosystèmes comme des « fonds écologiques ». Nous montrons que les modes de régulation existants, basés sur les concepts de services écosystémiques et de biens communs, considèrent les fonds comme donnés et se concentrent sur la production de flux. Le fait de reconnaître la dimension ouverte, partiellement inconnue, des fonds écologiques, permet d’initier des processus de conception collectifs d’écosystèmes innovants.

From Tf-Idf to Learning-to-Rank
Authors: Ibrahim Muhammad , Murshed Manzur
Published: September 2015

Ranking a set of documents based on their relevances with respect to a given query is a central problem of information retrieval (IR). Traditionally people have been using unsupervised scoring methods like tf-idf, BM25, Language Model etc., but recently supervised machine learning framework is being used successfully to learn a ranking function, which is called learning-to-rank (LtR) problem. There are a few surveys on LtR in the literature; but these reviews provide very little assistance to someone who, before delving into technical details of different algorithms, wants to have a broad understanding of LtR systems and its evolution from and relation to the traditional IR methods. This chapter tries to address this gap in the literature. Mainly the following aspects are discussed: the fundamental concepts of IR, the motivation behind LtR, the evolution of LtR from and its relation to the traditional methods, the relationship between LtR and other supervised machine learning tasks, the general issues pertaining to an LtR algorithm, and the theory of LtR.
The Human Side of Information Systems
Authors: Henriques Telmo Antonio , O'Neill Henrique
Published: September 2015

In this chapter the authors explore the relationship between Information Systems and Organization Development, highlighting the value that Holistic Change Interventions can introduce when applied to IS/IT areas, mobilizing Individuals, Groups and the whole Organization to promote Organizational Effectiveness. A “soft” approach to Organizational Change is proposed, focusing on main internal aspects which are determinant for Organizational Performance, including Organizational Culture and Values, Leadership, Work Teams, and Employee Engagement. The approach is illustrated by a successful “real-world” Transformational Change Program which has been developed, within an IT Unit of a major financial organization, following an Action Research paradigm. The intervention has integrated two main cycles – a first one covering the strategy determination and behavioral preparation for further action, and a second one devoted to a coordinated implementation of strategic actions which have emerged from the first cycle – where communication, engagement, action and improvement have been the most relevant attributes of the whole process. From a Research perspective this successful Change intervention has served to develop and test, within context, a Framework of Critical Success Factors for Holistic Change, which is described on its management implications, and covering distinct areas and dimensions. Also, the high potential of Action Research, to promote Holistic Change within real organizational settings, and, simultaneously, to address complex research issues, questions, objectives, and test hypothesis, is deeply illustrated within this chapter.

Formulating a Framework for Desktop Research in Chinese Information Systems
Authors: Zhou Lihong , Nunes Miguel Baptista
Published: September 2015

The investigation of information systems (IS) development usually relies on two different research approaches, namely, quantitative approach and qualitative approach. Both approaches are equally important and useful to the development of IS theories. No research approach should be considered to be superior or inferior to the other. However, the mainstream of Chinese IS research mainly follows the quantitative approach, whereas the qualitative approach is generally viewed as “too soft” or not scientific enough. As a qualitative approach, desk case-study research approach has been widely accepted and applied in a number of IS research in the West. However, in China, this approach is merely considered as an effective approach for teaching, but not valid for scientific research investigations. Thus, Chinese IS research have neglected a number of important experiences, viewpoints and lessons, which can be elicited from IS case-studies occurred in the past. This chapter generally aims at introducing and discussing the desk case-study approach in IS research. Specifically, this chapter discusses this approach through four incremental research stages, namely, defining the research question, establishing theoretical framework from literature review, case-study selection, and theory formulation through case-study analysis. Furthermore, two exemplary research projects are presented in this chapter to further clarify and substantiate the research methods, tools and processes. It is expected that by formulating a rigorous research framework and specifying incremental processes of theory development, this research approach could be accepted and used by Chinese IS scholars in the future.
Customer Experience Management System at a University's Student Support Services
Authors: Kouassi Amevi , Martins Jorge Tiago , Molnar Andreea
Published: September 2015

The study reported in this chapter evaluates how the Customer Experience Management System (CEMS) used by a University's Student Support Services (StuSS) responds to the objectives of capturing, storing, extracting, interpreting, distributing, using and reporting customer experience information for creating organisational value. Theoretically, the study draws on the concept of organizational ambidexterity. Concerning the research design, the study was undertaken using qualitative methods of data collection and interpretivist methods of data analysis. It has been inductively discovered that the availability of customer experience information obtained through the CEMS allows StuSS to respond effectively to different student needs. Organizationally, there is clarity concerning the ownership and management of customer relationships. Individual student data is collected, coordinated and distributed across lines of business. Because of this, StuSS is able to consistently identify customers across touch points and channels. Further suggestions are advanced to improve StuSS's analytical investigation capability to derive descriptive and predictive customer information, through applying data mining models to the information that is currently collected.
Nonverbal Learning Disorder
Authors: Casey Joseph E.
Published: September 2015

Since the first description of nonverbal learning disorder (NLD) was published in 1967, much research has been conducted elucidating its key features, its neuroanatomical associations, and the assessment procedures essential to establishing a diagnosis and treatment plan. Although there is theoretical and empirical evidence supporting the validity of NLD, awareness of this disorder is lacking, arguably in large part due to its absence in any formal classification system. This chapter reviews the scientific literature that has given rise to our current conceptualization of NLD. Clinical practice considerations are discussed as related to its assessment, diagnosis, treatment, and prognosis. These considerations are illustrated by a case study. The chapter continues with a discussion of issues in need of further research and the benefits of considering NLD in the context of the World Health Organization's classification system for describing health and health-related conditions. The chapter ends with a proposed definition of NLD.
Case Studies
Authors: Rissman Barbara
Published: September 2015

This chapter is taken from five illustrative case study reports resulting from doctoral research. Each case gave the researched a voice. The study selected five students at Level 1 risk of manifesting virtually all NLD assets and deficits as a consequence of shunted hydrocephalus related to spina bifida then spoke with their parents, teachers, aides and the students themselves. Each case begins with a brief description of the medical condition that predisposed each child to NLD followed by the contextual setting derived from family members. A snapshot of each student's life, classroom performance, psychological test results, teacher, aide, and parent perceptions of functional abilities, and the level of each participant's awareness of the NLD syndrome are then considered. Interpretative Discussions include teacher and aide understandings of the difficulties interspersed with those of the author. Practical help from teachers, aides, parents, and students is offered at the end of each case study. Case Studies conclude with a catalog of Key Terms and Definitions.

Authors: Jánoš Rudolf , Varga Jozef
Published: September 2015

This article describes the possibilities of identifying a randomly distributed objects due to the removal of parts from the conveyor belt, which is part of the workplace for assembly of the components. A specific feature of this work is that the installation is carried out with the robot SCARA, which take parts from the conveyor. Parts on the conveyor are unoriented, therefore it is necessary to use a camera system to detect the position and orientation of parts. Because of this, it is necessary to carry out the control lines across the moving conveyor. Recognition, identification, location and orientation of the proposed method is sufficiently robust and easily adaptable to the different type of components.

Authors: Bzdyra Krzysztof , Bocewicz Grzegorz , Banaszak Zbigniew
Published: September 2015

Declarative framework enabling to determine conditions employed in a decision support systems aimed at small and medium size enterprises involved in a unique, multi project-like and mass customized oriented production is discussed. The unique production orders grouped into the set of portfolio orders is considered. To each production order treated as an activity network of common shared resources, known in advance, however by nature imprecise operation times are allotted. The problem concerns of scheduling of a newly inserted projects portfolio taking into account imprecise operations imposed by a multi–project environment. The answer sought is: Whether a given portfolio can be completed within assumed time period in a manufacturing system in hand? The goal is to provide a declarative model enabling to state a constraint satisfaction problem aimed at multi project-like and mass customized oriented production scheduling. The attached calculation example illustrates the computational efficiency of the proposed solution.

Published: September 2015

The aim of this paper is to presents an interdisciplinary approach to the problem of manufacturing process support using Artificial Intelligence (AI) by introducing a cross physical-information control system concept. The scope of the article covers description of logical architecture concept, data exchange process and autonomous steering mechanism using artificial intelligent method. The article indicates that in order to successfully support manufacturing process using Artificial Intelligence proper logical support system architecture need to be applied. It is important to emphasize that the use of AI method is not enough to cover multidimensional production issues of gathering and processing data. Therefore whole system need to be organized in this way to support AI with data to be processed. Thanks to that, it is possible to meet many different goals and achieve significant results in the field of manufacturing process. Because of that in this paper the main focus is put on system logical architecture with descriptions of each element involved. Moreover, the article describes AI controller mechanism applied running on real time raw data collected from machines and products. Findings presented within paper could be use in real case scenarios as a design pattern to develop, deploy or optimize production management systems in small-medium enterprises based on low cost solutions of Internet of Things (IoT) providing data to be analyzed with use of cloud computing technology running AI algorithms.
Prediction of Rotorcraft Design Impacts on Maneuverability Characteristics
Authors: Johnson Kevin L. , Boling Bryan K.
Published: September 2015

Designing for helicopter missions requires maneuverability characteristics to be determined. These required maneuverability analyses are combinatorial in nature and involve human interaction, which hinders their integration into conceptual design. To address this issue, a model formulation
is presented that includes the necessary quantitative measures to analyze the operational envelope and captures the impact of changing requirements in real time. Through quantitative analysis of the pop-up maneuver space, this formulation is shown to provide a more conservative estimate of
maneuverability than traditional energy-based formulations commonly used in early design studies.

Published: September 2015

Background

The burden of diabetes mellitus (DM) is on the rise especially in developing countries like India. Due to its chronic nature DM tends to cause many debilitating complications and diabetic peripheral neuropathy (DPN) is one of them. The aim of this study is to determine the prevalence of DPN among patients attending a tertiary care hospital and to identify the determinants associated with it.

Design and methods

A cross sectional study was conducted in Government Wenlock Hospital, Mangalore (India), during January-February 2014. A total of 208 patients with >5 year duration of DM were asked to respond to the patient history version of Michigan Neuropathy Screening Instrument (MNSI) and examinations were conducted after obtaining consent from them. The statistical analysis was done in terms of descriptive statistics and association between variables was tested using logistic regression test.

Results

The prevalence of DPN using the MNSI history version and MNSI examination were found to be 18.3% and 32.2% respectively. The major determinants associated with DPN were found to be male gender (OR: 2.7, CI: 1.4-5.1, P=0.001), smoking (OR: 5.8, CI: 1.9-17.3, P=0.001) and age >40 years (OR: 2.7, CI: 1.2-5.8, P=0.011).

Conclusions

The burden of undetected DPN was found to be higher among diabetics, with an especially higher prevalence among males, smokers and those with long standing diabetes mellitus. Interventions in the form of early detection through routine screening, smoking cessation and regular follow up examinations would go a long way in reducing the burden of disability among diabetics and improve their quality of life significantly.
From Disappointment to Holistic Ideals: A Qualitative Study on Motives and Experiences of Using Complementary and Alternative Medicine in Sweden
Authors: Danell Jenny-Ann
Published: September 2015

Background

Recent studies indicate increased use of complementary and alternative medicine (CAM) in western societies, to ameliorate health problems. Even if there is substantial research on general patterns of use, there is limited knowledge on individual motives. This study contributes to a qualitative understanding of experiences of choosing and using CAM.

Design and methods

This study consists of in-depth interviews with 10 CAM users in Sweden. The participants represent different backgrounds and experiences of using CAM. The interviews have been analysed in accordance with content analysis.

Results

In analysing experiences of choosing and using CAM four main themes were identified: frustration and critique, values and ideology, individual responsibility, and combining treatments. In general, the participants were highly reflexive on issues concerning their health. They highlighted their own role and responsibility, combined a variety of treatments, and continuously dealt with questions on risks, even if they had relatively different approaches to if and when to use CAM. The results also show that motives may change over time. Even if initial choices were closely related to frustration and critique of conventional treatments (for example, by perceiving conventional health care as limited, not receiving proper diagnoses, or being critical to conventional drugs) was long-term use motivated by ideological characteristics of CAM (such as holistic and individualized treatments, and extensive interaction with practitioners).

Conclusions

Four main themes, concerning experiences of choosing and using CAM were identified. This study also supports the idea that initial motives for choosing CAM may differ from those explaining long-term use.

Background

The aim of the study is to assess the long-term secondary effects of personal experience with the H1N1 pandemic of 2009/2010 and the perception of the institutional reaction to it on Italians’ willingness to get vaccinated in case of a novel influenza pandemic.

Design and Methods

We conducted 140 face-to-face interviews in the Registry Office of the Municipality of Milan, Italy, from October to December 2012.

Results

Willingness to get vaccinated during a novel influenza pandemic was best predicted by having been vaccinated against the seasonal flu in the past (OR=5.18; 95%CI: 1.40 to 19.13) and fear of losing one's life in case of an infection with H1N1 (OR=4.09; 95%CI: 1.68 to 9.97). It was unaffected by the assessment of institutional performance.

Conclusions

The findings of this study do not point to long-term secondary effects of the institutional handling of the H1N1 pandemic. The results highlight the fact that behavioural intention is not the same as behaviour, and that the former cannot simply be taken as an indicator of the latter.

О дискретном спектре гамильтонианов $n$-частичных систем при $n\to\infty$ в пространствах функций различной перестановочной симметрии
Authors: Zhislin Grigorii Moiseevich

Рассматриваются ограничения нерелятивистского оператора $H_n$ энергии относительного движения системы $n$ тождественных частиц с короткодействующими потенциалами взаимодействия на подпространства $\{M\}$ функций различной перестановочной симметрии. Для каждого из этих ограничений доказано существование такой бесконечной возрастающей последовательности чисел $N_j$, $j=1,2,…$, что дискретный спектр оператора $H_{N_j}$ на $M$ непуст. Совокупность
$\{M\}$ рассмотренных подпространств, по-видимому, близка к максимальной при применении существующих методов изучения.
Обзор алгебраических действий дискретной группы Гейзенберга
Authors: Lind Douglas , Schmidt Klaus
Published: September 2015

В последнее время теория действий счетных групп автоморфизмами на компактных абелевых группах получила большое развитие и открыла глубокие связи с операторными алгебрами и другими областями математики. Дискретная группа Гейзенберга является простейшей некоммутативной группой, для которой феномены динамики, порожденные некоммутативностью, позволяют продемонстрировать многие из этих связей. Прозрачная структура группы позволяет дать конкретное описание этих феноменов, что является не только стартовой точкой для общей теории, но и проверочным полигоном для будущих исследований. Мы приводим обзор того, что известно о действиях счетной группы Гейзенберга, разбирая многочисленные примеры и формулируя нерешенные вопросы.

Дан краткий обзор фактов, касающихся бесконечных прямых струн, а также получено уравнение гравитационной линзы от бесконечной струны в классическом виде и подробно анализируются особенности гравитационного линзирования на данном объекте. Рассматривается конечная прямая струна. Приводятся каустики и критические кривые для струн различной длины, а также некоторые изображения, которые дает рассматриваемая гравитационная линза. Предлагается метод численного построения кривых блеска, в качестве примера работоспособности данного метода строится конкретная кривая блеска для определенных параметров гравитационной линзы.
Процессы, вкладывающиеся в геометрическое броуновское движение

Основной результат является аналогом теоремы Монро (1978) в случае геометрического броуновского движения: случайный процесс эквивалентен замене времени в геометрическом броуновском движении тогда и только тогда, когда он есть неотрицательный супермартингал. Мы также указываем на связь нашего основного результата с работой Монро (1972). Эта связь основана на понятии минимального момента остановки и его характеризации в работах Монро (1972) и Кокса и Хобсона (2006) в случае броуновского движения. В заключение мы предлагаем достаточное условие для минимальности для процессов, отличных от броуновского движения, дополняя обсуждение в указанных работах.

Ergodicity test of the eddy-covariance technique

Abstract. The ergodic hypothesis is a basic hypothesis typically invoked in atmospheric surface layer (ASL) experiments. The ergodic theorem of stationary random processes is introduced to analyse and verify the ergodicity of atmospheric turbulence measured using the eddy-covariance technique with two sets of field observational data. The results show that the ergodicity of atmospheric turbulence in atmospheric boundary layer (ABL) is relative not only to the atmospheric stratification but also to the eddy scale of atmospheric turbulence. The eddies of atmospheric turbulence, of which the scale is smaller than the scale of the ABL (i.e. the spatial scale is less than 1000 m and temporal scale is shorter than 10 min), effectively satisfy the ergodic theorems. Under these restrictions, a finite time average can be used as a substitute for the ensemble average of atmospheric turbulence, whereas eddies that are larger than ABL scale dissatisfy the mean ergodic theorem. Consequently, when a finite time average is used to substitute for the ensemble average, the eddy-covariance technique incurs large errors due to the loss of low-frequency information associated with larger eddies. A multi-station observation is compared with a single-station observation, and then the scope that satisfies the ergodic theorem is extended from scales smaller than the ABL, approximately 1000 m to scales greater than about 2000 m. Therefore, substituting the finite time average for the ensemble average of atmospheric turbulence is more faithfully approximate the actual values. Regardless of vertical velocity or temperature, the variance of eddies at different scales follows Monin–Obukhov similarity theory (MOST) better if the ergodic theorem can be satisfied; if not it deviates from MOST. The exploration of ergodicity in atmospheric turbulence is doubtlessly helpful in understanding the issues in atmospheric turbulent observations and provides a theoretical basis for overcoming related difficulties.
