Organizational learning model for sustainable innovation: elements for a new innovation approach in developing countries
Authors: Rivera Vargas Maria Isabel 
Published: July 2011

Résumé La recherche en apprentissage organisationnel et sur la construction de capacités pour le développement technologique et l’innovation sont faibles dans les pays en développement. Ceci est paradoxal puisqu’il existe un besoin impérieux de modèles théoriques qui se saisissent de l’apprentissage organisationnel et du changement technologique dans ces pays en tant que pré-requis important pour comprendre le processus dynamique de construction de ces capacités ; il s’agit de concevoir et promouvoir des stratégies appropriées pour le développement industriel soutenable. L’objectif de cet article est par conséquent d’attirer l’attention sur la pertinence de l’apprentissage organisationnel pour la construction de telles capacités et de proposer une approche plus adéquate pour promouvoir et réussir l’innovation. A travers l’analyse d’un modèle d’apprentissage technologique qui a montré son efficacité sous d’autres latitudes, nous proposons tout d’abord le renforcement de la Production-Ingénierie, puis lors des étapes suivantes, le renforcement du Développement et de la Recherche-Innovation, respectivement (PI-D-RI) inversant ainsi le rapprochement orthodoxe Recherche, Développement, Ingénierie (R-D-I). Cette approche permet ainsi l’adaptation du modèle tant, d’un point de vue conceptuel, à la théorie du développement soutenable de Morin (1999), qu’aux circonstances et possibilités actuelles des petites et moyennes entreprises dans les pays en voie de développement, d’un point de vue plus opérationnel.
Une jalousie de rêve
Authors: Baldacci Chantal 
Published: July 2011

Résumé Dans le texte étudié, Freud pense tirer de l’étude « intensive de deux paranoïaques quelque chose de nouveau ». Le nouveau serait que le rêve dans les deux cas, tantôt précurseur, tantôt substitut du délire, accueille « ce qui de la vie de veille était... repoussé ». Un moment passionnel dans la cure analytique d’une jeune femme permet de repérer les conditions qui influencent la répartition équilibrée de l’investissement entre réalité et rêve, veille et nuit, dehors et dedans et permettent au rêve de devenir un substitut du délire. Dans cette cure, un agir de contre-transfert participerait à la perlaboration onirique du transfert.
Investissements narcissiques et projection dans la cure
Authors: Chervet Emmanuelle 
Published: July 2011

Résumé La clinique évoquée au cours du colloque a montré que des investissements narcissiques intenses – jalousie, paranoïa, homosexualité – permettent dans la cure une approche projective de contenus de l’histoire inabordables. Ces mécanismes recoupent ceux de la répétition agie de transfert abordée en 1915, à travers divers objets rappelant ceux de l’article de 1922. Leur liaison au transfert par l’analyste permet secondairement leur élaboration dans le registre représentatif. L’accès à un fonctionnement en identité de pensée et le dégagement du registre spéculaire manifestent l’installation devenue possible d’un processus de cure classique.
Trame de la jalousie
Authors: Laffont Isabelle , Servant Benoît 
Published: July 2011

Résumé Les auteurs proposent d’éclairer la compréhension de l’expérience jalouse par l’analyse d’une nouvelle de S. Zweig, La Peur . Celle-ci les amène à considérer la jalousie comme une tentative d’élaboration de la dimension traumatique et séductrice de la relation à autrui, elle-même consécutive à la défaillance de l’homosexualité primaire en double. Il y aurait une affinité particulière entre la fantasmatisation jalouse et l’écriture romanesque. Par analogie, le travail de l’analyste (tel qu’il est présenté à partir de la reprise des cas de C. Baldacci et de J. Press, ainsi que d’un cas personnel) consisterait à « tisser » des représentations, en même temps qu’à se laisser atteindre par le patient pour l’aider à exorciser sa crainte de l’objet. Il peut ainsi favoriser la réintrojection de l’expérience primitivement projetée.
Regards psychanalytiques sur la non-violence de Gandhi
Authors: Cervera-Marzal Manuel 
Published: July 2011

Résumé Les sciences sociales « classiques » ne sont pas parvenues à fournir une réponse adéquate à la question des motifs ayant poussé Gandhi à opter pour la non-violence. La métapsychologie, en revanche, invite à l’hypothèse suivante : le Mahatma prônait la non-violence pour se défendre de l’agressivité des fils. Cette idée peut paraître fantaisiste. Elle est pourtant fondée sur de nombreuses congruences, parfois troublantes, entre la biographie de Gandhi et le mythe freudien du meurtre du père. Notre article vise, au fond, à montrer comment la science de l’inconscient, loin d’être applicable au seul domaine de l’individu, constitue un apport à la compréhension du fait social et historique.
De l'économie de guerre au secours philanthropique : care et les enjeux de l'aide américaine dans l'Europe de l'après-guerre
Authors: Farré Sébastien 
Published: July 2011

Résumé Fondé en novembre 1945, le Committee for Assistance and Remittance for Europe ( care ) est exemplaire des enjeux et des problèmes des actions de secours de l’immédiat après-guerre. Cette agence issue de la tradition philanthropique américaine a comme principal objet l’envoi de colis alimentaires financés par des donateurs étasuniens en faveur de particuliers européens. Produit de la guerre totale, care réélabore des techniques de production et de mobilisation issue de l’économie de guerre. Le modèle care s’inscrit dans une économie de l’humanitaire pour s’imposer rapidement comme un instrument très apprécié d’une diplomatie de la compassion et du secours. D’une certaine manière, les colis estampillés care - usa privatisent des pratiques développées par l’armée en modifiant le rapport entre le donateur et les « victimes ».
Dynamique cognitive et risques psychosociaux : isolement et sentiment d'isolement au travail
Authors: Marc Jacques , Grosjean Vincent , Marsella M. C. 
Published: July 2011

Résumé L’article vise à poser les bases théoriques d’une approche de l’isolement professionnel considéré comme un risque psychosocial, pour examiner ensuite les difficultés théoriques pour approcher ce phénomène d’isolement. On distinguera d’une part le sentiment d’isolement, qui apparaît dès lors que le salarié estime ne pas pouvoir disposer de soutien en cas de difficulté, d’autre part le sentiment de solitude, lorsqu’un renoncement à chercher quelque soutien que ce soit apparaît. S’agissant de sentiment, le terme sera précisé : il renvoie à une émotion, à un vécu corporel signant une insatisfaction issue du rapport individu-milieu. Nous préciserons en quoi les émotions jouent un rôle régulant pour l’activité individuelle et collective, à l’instar des erreurs dans un autre cadre théorique. Cette approche sera illustrée dans le cadre d’une demande d’intervention d’une entreprise de transport urbain. La conclusion se concentrera sur les difficultés méthodologiques relatives aux questions touchant l’isolement professionnel et sur l’intérêt d’ouvrir la question des rps à aux approches utilisées en psychologie ergonomique.
The Role of Standardized Protocols in Unplanned Extubations in a Medical Intensive Care Unit
Authors: Jarachovic Mary , Mason Maggie , Kerber Kathleen , McNett Molly 
Published: July 2011

BackgroundMany patients admitted to medical intensive care units require mechanical ventilation to assist with respiratory management. Unplanned extubations of these patients are associated with poor outcomes for patients and organizations. No previous research has investigated the role of standardized protocols in unplanned extubations when examined in conjunction with traditional risk factors.ObjectiveTo identify risk factors associated with unplanned extubation among patients receiving mechanical ventilation and determine degree of compliance with pain, sedation, and weaning protocols.MethodsA prospective cohort study design was used. Data on all patients admitted to the medical intensive care unit who required mechanical ventilation were gathered daily. Additional data were gathered on those patients who experienced unplanned extubation. Descriptive, correlational, and regression analyses were performed.ResultsWeaning protocols were a significant predictor of unplanned extubation: patients who had weaning protocols ordered and followed were least likely to experience unplanned extubation. Only 10% of the 190 patients in the study required reintubation, resulting in a significantly shorter ventilation time and unit length of stay among the unplanned extubation group.ConclusionsWeaning protocols were associated with decreased incidence of unplanned extubation. Use of standardized protocols was feasible, as compliance among health care providers was high when protocols were medically prescribed. The reintubation rate in this study was low and associated with a significantly shorter ventilatory period and unit length of stay in the unplanned extubation group.
Awareness and Reported Consequences of a Cigarette Tax Increase among Older Adolescents and Young Adults
Authors: Choi T. C. Kelvin , Toomey Traci L. , Chen Vincent , Forster Jean L. 
Published: July 2011

Purpose: To determine the prevalence and predictors of the awareness of cigarette price increases following a cigarette tax increase, and assess the association of the tax increase and attempts to quit and reduce smoking among adolescents and young adults. Design: We used a prospective cohort design. Setting: Surveys were conducted in Minnesota before and after a $0.75 cigarette tax increase Subjects: We surveyed 3167 adolescents and young adults, including a subsample of 781 past–30-day smokers. Measures: Outcome measures were awareness of cigarette price increases and, among past–30-day smokers, reported changes in smoking behaviors because of the tax increase. Predictors included demographics, social factors, and prior smoking behaviors. Analysis: We estimated the prevalence of the outcomes and their associations with the predictors using logistic regression. Results: Among all participants, 42% noticed an increase in cigarette prices after the tax increase, including 76% of past–30-day smokers. Being a heavier smoker, living with smokers, having more smoking close friends, and generally being aware of cigarette price changes prospectively predicted the awareness of the price increase after the tax increase. Among past–30-day smokers, 16.7% reported quit attempts and 24.1% reported reducing smoking because of the tax increase. Conclusion: Because fewer than half of the participants noticed the cigarette tax increase, media campaigns to raise awareness of tax changes may increase their effectiveness.
Physical Activity in the Context of Clustering Patterns of Health-Promoting Behaviors
Authors: Tsuboi Satoshi , Hayakawa Takehito , Kanda Hideyuki , Fukushima Tetsuhito 
Published: July 2011

Purpose. To describe differences in physical activity in the context of clustering patterns of health-promoting behaviors. Design. A cross-sectional study with 1724 participants (response rate, 91.1%). Setting. Tadami Town, in a rural area of Fukushima Prefecture, Japan. Subjects. Part of the general population who participated in annual health checkups (age range, 30–93 years). Measures. The Health-Promoting Lifestyle Profile II was used to assess frequency of health-promoting behaviors (physical activity, health responsibility, spiritual growth, interpersonal relationships, nutrition, and stress management). Smoking status, alcohol consumption, and disease status were self-reported. Public health nurses measured the weight and height of participants. Analysis. Cluster analysis was conducted to identify clustering patterns of health-promoting behaviors other than physical activity. Differences in physical activity between identified clusters were examined by multiple logistic regression analysis. Results. Four clusters were identified and labeled as “Most challenged” (20.4%), “Adherence to norms” (30.3%), “Well in mentality” (20.9%), and “Health-promoting” (28.4%). “Health-promoting” was the most physically active cluster, followed by “Adherence to norms” and “Well in mentality.” Conclusions. Although the survey methodology was subject to selection, self-report, and recall biases, we have described physical activity in the context of clustering patterns of health-promoting behaviors. Laying the groundwork for physical activity in the lifestyle is important for establishing health-promotion strategies to increase physical activity.
Food-Related Environmental, Behavioral, and Personal Factors Associated with Body Mass Index among Urban, Low-Income African-American, American Indian, and Caucasian Women
Authors: Dammann Kristen Wiig , Smith Chery 
Published: July 2011

Purpose. To examine racial/ethnic differences in relationships between food-related environmental, behavioral and personal factors and low-income women's weight status using Social Cognitive Theory (SCT) as a framework. Design. Cross-sectional survey. Setting. Community sites and low-income housing developments in the Twin Cities metropolitan area. Subjects. Low-income African-American, American Indian, and Caucasian women ≥ 18 years old (n = 367). Measures. Participants completed a survey including demographic, food security, and theoretically based questions. Heights and weights were measured to determine body mass index (BAI). Analysis. Data were split by race/ethnicity and reduced by examining Pearson coefficients for SCT survey questions significantly correlated with BMI (p < .05). Separate environmental, behavioral, and personal multiple linear regression models for each racial/ethnic group were run to explore the proportion of variance in BMI explained by each SCT construct and which questions were significant predictors. Results. All regression models were statistically significant, although the personal regression models predicted the greatest proportion of the variance in BMI for African-American (15% of the variance), American Indian (22% of the variance), and Caucasian women (37% of the variance). Conclusion. Effective nutrition education and intervention efforts to control the obesity epidemic among urban, low-income women may call for a tailored approach with noted consideration of their racial/ethnic identity. Although broader changes to the food environment are necessary, the importance of addressing personal factors such as nutrition knowledge, self-efficacy, and emotional coping responses to stress, in the context of income constraints, food insecurity, and health beliefs, is also implicated.

Abschied vom HSAB‐Modell ambidenter Reaktivität
Authors: Mayr Herbert , Breugst Martin , Ofial Armin R. 
Published: July 2011

AbstractDas Konzept harter und weicher Säuren und Basen (HSAB) erwies sich als nützlich, um die Stabilitätskonstanten von Metallkomplexen zu erklären. Seine Anwendung auf organische Reaktionen, insbesondere zur Deutung ambidenter Reaktivität, hat jedoch exotische Blüten hervorgebracht. Beim Versuch, alle beobachteten Regioselektivitäten durch günstige Weich‐weich‐ und Hart‐hart‐Wechselwirkungen sowie durch ungünstige Hart‐weich‐Wechselwirkungen zu erklären, wurden frühere Deutungen ambidenter Reaktivität ersetzt, die korrekt zwischen thermodynamischer und kinetischer Kontrolle sowie zwischen unterschiedlichen Koordinationsweisen ionischer Substrate unterschieden haben. Durch Nichtbeachtung widersprechender experimenteller Befunde und sogar Bezug auf nicht auffindbare experimentelle Daten erhielt die HSAB‐Behandlung ambidenter Reaktivität unverdiente Popularität. In diesem Aufsatz zeigen wir, dass das HSAB‐Konzept, wie auch das damit verwandte Klopman‐Salem‐Modell, nicht einmal das Verhalten der Prototypen ambidenter Nucleophile richtig beschreibt, sodass es eher irreführend denn ein nützlicher Wegweiser ist. Eine alternative Behandlung ambidenter Reaktivität auf der Basis der Marcus‐Theorie wird vorgestellt.
Farewell to the HSAB Treatment of Ambident Reactivity
Authors: Mayr Herbert , Breugst Martin , Ofial Armin R. 
Published: July 2011

AbstractThe concept of hard and soft acids and bases (HSAB) proved to be useful for rationalizing stability constants of metal complexes. Its application to organic reactions, particularly ambident reactivity, has led to exotic blossoms. By attempting to rationalize all the observed regioselectivities by favorable soft–soft and hard–hard as well as unfavorable hard–soft interactions, older treatments of ambident reactivity, which correctly differentiated between thermodynamic and kinetic control as well as between different coordination states of ionic substrates, have been replaced. By ignoring conflicting experimental results and even referring to untraceable experimental data, the HSAB treatment of ambident reactivity has gained undeserved popularity. In this Review we demonstrate that the HSAB as well as the related Klopman–Salem model do not even correctly predict the behavior of the prototypes of ambident nucleophiles and, therefore, are rather misleading instead of useful guides. An alternative treatment of ambident reactivity based on Marcus theory will be presented.
Gold α‐Oxo Carbenoids in Catalysis: Catalytic Oxygen‐Atom Transfer to Alkynes
Authors: Xiao Jian , Li Xingwei 
Published: July 2011

AbstractAn overview of reactive gold α‐oxo carbenoid intermediates in the gold‐catalyzed functionalization of alkynes is presented. Such intermediates can be generated from inter‐ and intramolecular oxidation of alkynes by nucleophilic oxygen‐atom donor groups, such as amine N‐oxides, pyridine N‐oxides, nitrones, nitro compounds, sulfoxides, and epoxides. These O‐atom transfer processes occur by gold‐mediated addition–elimination reactions. In catalytic systems, α‐oxo carbenoids can undergo nucleophilic attack by imine, arene, and migrating hydride as well as alkyl groups, leading to cascade reactions and the construction of new skeletons. The facile construction of CE (E=C, N, S, or O) bonds makes it an attractive step‐economic approach to value‐added molecules from readily available starting materials. The scope, mechanisms, and reactivity of such α‐oxo carbenoid species are discussed. The remarkable diversity of structures accessible is demonstrated with various recent examples.

Authors: Wang Guoliang , Zhang Qingling 
Published: July 2011

AbstractThis paper is concerned with the robust H∞ control problem for a class of Markovian jump systems with uncertain switching probabilities, whose uncertainties are assumed to be elementwise bounded. First, new criterion of H∞ performance for such uncertain systems is given. Then, new sufficient condition for H∞ controller is established as strict linear matrix inequalities. Finally, a numerical example is used to demonstrate the effectiveness of the proposed methods.Copyright © 2011 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society
Stabilization strategy for unstable first order linear systems with large time‐delay
Authors: Márquez‐Rubio J. F. , del Muro‐Cuéllar B. , Velasco‐Villa M. , Álvarez‐Ramírez J. 
Published: July 2011

AbstractThis work considers the problem of stabilization of a class of unstable first order linear systems subject to a large input‐output time delay. Necessary and sufficient conditions are stated to guarantee the stability of the closed loop delayed system by means of a compensation scheme based on two static gains and an induced delay term. The proof of the main result is derived by considering a discrete time approach that, under adequate assumptions, allows to conclude the stability condition for the continuous time case.Copyright © 2011 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society
Robust stabilization for discrete‐time nonlinear singular systems with mixed time delays
Authors: Li Jianning , Su Hongye , Wu Zhengguang , Chu Jian 
Published: July 2011

AbstractThis paper investigates the robust stability of discrete‐time singular systems involving nonlinear disturbance and mixed time delays. The mixed time delays are comprised of both discrete and distributed delays. The interval of discrete time delays can be divided into several subintervals, firstly. Then, in terms of linear matrix inequality (LMI), a suitable state feedback controller is designed for discrete‐time singular systems with nonlinear disturbance and mixed time delays, and the overall closed‐loop system is regular, causal and mean square asymptotically stable. Numerical examples are provided to show the usefulness and effectiveness of the proposed methods, and the results derived from our approaches are less conservative than existing ones.Copyright © 2011 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society
Multi‐objective H2/L2 performance controller synthesis for LPV systems
Authors: Xie Wei 
Published: July 2011

AbstractThis paper provides a kind of new matrix inequalities formulation for multi‐objective H2/L2 performance controller synthesis of linear parameter varying systems. These new matrix inequalities enable us to parameterize controllers without involving the Lyapunov variables in the formulation. Taking advantage of this feature, we can readily design multiobjective controllers with non‐common parameter‐dependent Lyapunov variables and two adjustable scalars. Furthermore, to obtain possibly lower values of performance criteria, a linear matrix inequalities (LMI)‐based optimal problem is solved by using the grid of the space that is combined with these two scalars. Finally, a numerical example is included to illustrate the effectiveness of the proposed method.Copyright © 2011 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society
Scale‐down of penicillin production in Penicillium chrysogenum

AbstractIn large‐scale production reactors the combination of high broth viscosity and large broth volume leads to insufficient liquid‐phase mixing, resulting in gradients in, for example, the concentrations of substrate and oxygen. This often leads to differences in productivity of the full‐scale process compared with laboratory scale. In this scale‐down study of penicillin production, the influence of substrate gradients on process performance and cell physiology was investigated by imposing an intermittent feeding regime on a laboratory‐scale culture of a high yielding strain of Penicillium chrysogenum. It was found that penicillin production was reduced by a factor of two in the intermittently fed cultures relative to constant feed cultivations fed with the same amount of glucose per hour, while the biomass yield was the same. Measurement of the levels of the intermediates of the penicillin biosynthesis pathway, along with the enzyme levels, suggested that the reduction of the flux through the penicillin pathway is mainly the result of a lower influx into the pathway, possibly due to inhibitory levels of adenosine monophosphate and pyrophosphate and lower activating levels of adenosine triphosphate during the zero‐substrate phase of each cycle of intermittent feeding.
