Dans une économie globalisée actuelle, où l’environnement entrepreneurial est défini comme incertain et turbulent, les entreprises choisissent les stratégies de coopétition pour avoir des avantages et performances. Mais, selon la littérature spécialisée, si les avantages et les performances, sont mis en avant pour justifier la pertinence des stratégies de coopétition, la notion d’opportunisme du partenaire est elle aussi largement investie et identifiée par des recherches comme un frein à la coopétition. C’est de cette façon, qu’on peut constater dans cette littérature, deux thèses différenciées qui caractérisent les analyses sur la coopétition ; une relation entre concurrents, source de performances hors normes et une relation fragile et instable à tout instant, à raison de l’opportunisme présumé du partenaire. L’opportunisme du partenaire s’avère particulièrement problématique en ce qu’il conduirait à limiter les performances et avantages attendus de la coopétition. L’objectif de cette recherche est d’établir un lien entre la performance de la coopétition et le capital social. Partant de l’opportunisme du partenaire, nous avons posé que la performance d’une coopétition est fonction de deux préalables : la réduction de l’opportunisme et l’augmentation de l’engagement des acteurs en relation. Une étude empirique est menée auprès des coopétitions des TPE minières exploitant le diamant au Kasaï, en République Démocratique du Congo. Une méthodologie qualitative permet le recueil des données par entretiens semi-directs, puis l’exploitation des termes des discours en se servant de l’outil lexicometrique, « Iramuteq ». L’objectif est de repérer les éléments déterminés de manière théorique, et qui traduisent soit les enjeux de la coopétition pour les TPE d’un environnement difficile, soit la pertinence du capital social dans la performance de la coopétition. Des liens établis entre la réduction de l’opportunisme, l’augmentation de l’engagement et les avantages tirés de la coopétition avec le capital social, constituent l’apport de cette recherche. Apport qui concerne les connaissances tant en management de la coopétition, que relatives aux TPE de contexte difficile. La variable-clé, « opportunisme » du partenaire, est la source du lien constaté entre la performance de la coopétition et le capital social. La logique suivie se décline en réponse aux interrogations formulées dans la littérature par différents auteurs au sujet de l’opportunsme qui conduit à la fragilité et à l’instabilité de la coopétition. Ce qui nous autorise de formuler un modèle vertueux de la performance de la coopétition par le capital social. A l’issu de notre étude empirique, une discussion sur des implications managériales est menée, aboutissant à une forme spécifique de coopétition mobilisant deux niveaux de réseau et des préconisations sont envisagées.

2. Fanti, Kostas Andrea. Trajectories of Pure and Co-Occurring Internalizing and Externalizing Problems from Age 2 to Age 12: Findings from the NICHD Study of Early Child Care.

Degree: PhD, Psychology, 2007, Georgia State University

According to previous research, internalizing and externalizing problems tend to be comorbid or co-occur at different ages in development (Angold, Costello, & Erkanli, 1999). The question that this dissertation addresses is how and why internalizing and externalizing problems, two disorders that represent separate forms of psychopathology, co-occur in children. This is an important question for the developmental psychopathology perspective because an appreciation of the concept of co-occurrence is essential for explaining the development and taxonomy of internalizing and externalizing psychopathology, and for understanding the etiology and course of these symptoms (Achenbach, 1990). Attempts to explain co-occurrence have proposed that co-occurring psychopathology might represent distinct, meaningful syndromes (Angold & Costello, 1992; O’Connor et al., 1998), and in support of this idea, evidence of the existence of pure and co-occurring internalizing and externalizing problems has been found (Keiley et al., 2003). However, no previous study has identified heterogeneous developmental patterns of pure or combined internalizing and externalizing problems within a dynamic framework by taking trajectories of change into account. This dissertation uses data from the NICHD study of Early Child Care to explore the co-occurrence between internalizing and externalizing problems from age 2 to 12 with the use of Latent Class Growth Analysis. The sample included 1232 children (52% male). Different groups of children exhibiting low/normative, pure internalizing, pure externalizing, and co-occurring internalizing and externalizing problems across the 10 year period were identified. The higher risk groups deviated from the low/normative group in terms of antecedents, SES risk, medical risk, difficult temperament, and home environment. Moreover, children who exhibited pure moderate externalizing problems, and children who exhibited chronic externalizing problems, with and without co-occurring internalizing problems, engaged in more risky behaviors and were more likely to have friends who also engaged in risky behaviors. Furthermore, the pure chronic externalizing group and the groups scoring high on internalizing problems, with and without co-occurring externalizing problems, were more asocial with peers. Finally, children exhibiting chronic co-occurring externalizing and internalizing problems were more excluded by peers in comparison to the rest of the sample’s population.
