Les alliances stratégiques connaissent depuis quelques décennies un fort essor tant en termes de pratiques managériales des entreprises qu’en termes de recherches académiques. Cet essor s’est accompagné de nombreuses controverses sur leurs issues (performances) et sur les facteurs les influençant. Par cette recherche, notre objectif est d’appréhender le phénomène des alliances stratégiques asymétriques en identifiant ses principales caractéristiques et les facteurs susceptibles d’influencer positivement ou négativement sa performance. Dans cette perspective, notre première phase de recherche a consisté en la réalisation d’un état de l’art sur les concepts des alliances stratégiques en général, des alliances asymétriques en particulier et de la performance. Sur cette base, nous avons pu établir huit hypothèses de recherche que nous avons ensuite testé en adoptant une démarche qualitative par étude de 10 cas d’alliances asymétriques. Notre application empirique a concerné les alliances stratégiques entre les PME françaises et les firmes multinationales opérant dans l’industrie aéronautique et a été conduite du point de vue des PME impliquées. L’analyse de nos hypothèses de recherche nous a permis d’obtenir trois résultats principaux : l’existence de liens forts entre les spécificités des partenaires et leurs motifs pour ces alliances; l’existence de liens négatifs importants entre certaines asymétries entre les partenaires (taille, culture organisationnelle et expériences d’alliances) et la performance relationnelle ; et l’existence de liens positifs importants entre la complémentarité des ressources des PME et des multinationales impliquées et leurs résultats quantitatifs (performance financière et apprentissage organisationnel). Nos résultats confortent certaines recherches antérieures sur les caractéristiques et la performance des alliances asymétriques. Ils peuvent aussi faire l’objet de recommandations pratiques aux dirigeants des PME impliquées dans ces relations. / Strategic alliances in recent decades experienced a strong growth both in terms of firms management practices and in terms of academic research. This growth has been accompanied by many controversy concerning their outcomes (performance) and the factors influencing these outcomes. Through this research, our objective is to understand the phenomenon of asymmetric strategic alliances by identifying its main characteristics and factors that may positively or negatively influence its performance. In this perspective, our research first phase consisted of the realization of a state of the art on the concepts of strategic alliances in general, asymmetric alliances in particular and performance. On this basis, we established eight research hypotheses that we tested by adopting a qualitative approach by studying 10 cases of asymmetric alliances. Our empirical application concerned strategic alliances between French SMEs and multinational companies operating in the aviation industry and was conducted from the perspective of SMEs involved. Analysis of our research hypotheses allowed us to obtain three main results: the existence of strong links between partners specificities and their alliances motivation; the existence of significant negative links between between partners asymmetries in terms of (size, organizational culture and experiences) and relational performance; and the existence of significant positive relationship between SMEs and multinationals involved resources complementarity and their quantitative results (financial performance and organizational learning). Our results confirm some previous research concerning of asymmetric alliances characteristics and performance. They can also be objects of practical recommendations to managers of SMEs involved in these relationships.

A global defensive alliance in a graph G = (V, E) is a set of vertices S ⊆ V with the properties that every vertex in V - S has at least one neighbor in S, and for each vertex v in S at least half the vertices from the closed neighborhood of v are in S. The alliance is called strong if a strict majority of vertices from the closed neighborhood of v are in S. The global defensive alliance number γa(G) (respectively, global strong defensive alliance number γâ(G)) is the minimum cardinality of a global defensive alliance (respectively, global strong defensive alliance) of G. We show that if T is a tree with order n ≥ 2, l leaves and s support vertices, then γâ (T) ≥ (3n - l - s + 4) /6 and γa (T) ≥ (3n - l - s + 4)/8. Moreover, all extremal trees attaining each bound are characterized.

Os hospitais são de extrema relevância para o bem estar e saúde da população, e assumem importante posição na sociedade devido a sua função social e econômica. Essas instituições possuem um ambiente complexo e dinâmico, com várias carências na gestão administrativa, de investimentos financeiros, de uma eficiente infraestrutura de suprimentos e equipamentos entre outras. A aliança logística está sobressaindo como oportunidade estratégica a agregar valor no setor hospitalar. Neste sentido, o objetivo desta tese é propor uma sistemática para a orientação do planejamento e operação de aliança logística entre hospitais. Para tanto, o trabalho utilizou uma abordagem qualitativa-exploratória, com estratégia de pesquisa embasada na pesquisa bibliográfica e estudo de casos múltiplos (07 hospitais). A seleção dos hospitais foi por análise de ranking das listas disponibilizadas pela JCI (Joint Commission International) e pelo \'Provão do SUS - Sistema Único de Saúde\', sendo escolhidos os cinco principais hospitais de cada uma, que localizassem no Estado de São Paulo. A coleta de dados foi realizada por meio de roteiro de entrevista semiestruturado com os responsáveis pelas áreas de suprimentos/logística e farmácia. Os resultados permitiram sistematizar quadros referenciais teóricos das características, motivos, facilitadores, benefícios, dificuldades, abordagens de gestão e propor uma sistemática de planejamento e operação da aliança logística entre hospitais. Também, concluiu-se que as alianças logísticas entre hospitais possuem foco na área de materiais médicos e medicamentos, por meio do desenvolvimento de atividades de empréstimos, trocas e consignações, negociação e compra conjunta. Essas relações podem proporcionar ganhos nos fluxos de materiais, medicamentos e informações, consequentemente melhores resultados em relação a custo, quantidade, tempo, lugar e qualidade, influenciando no nível de desempenho da prestação de serviço e no pronto atendimento ao paciente. / Hospitals are very important for the welfare and health of the population, and take on an important position in society because of its social and economic function. These institutions have a complex and dynamic environment, with several lacks in administrative management financial investments, efficient infrastructure supplies and equipment among others. The alliance logistics is standing out as a strategic opportunity to add value in the hospital sector. In this sense, the objective of this thesis is to propose a systematic for the orientation of the planning and operation of logistics alliance between hospitals. For this, the work used a qualitative and exploratory approach, based on the research strategy in bibliographic research and multiple cases study (07 hospitals). The selection of hospitals was by analysis of ranking lists provided by JCI (Joint Commission International) and the \'Provão SUS - Health System\', chosen the five main reference hospitals in each, which locate in the state of São Paulo. Data collection was performed using a semi-structured interview guide with those responsible for the area of supply/logistics and pharmacy. The results allowed systematizing theoretical reference frameworks of the characteristics, motives, facilitators, benefits, critical points, management approaches and proposing a systematic planning and operation of logistics alliance between hospitals. Also, it was concluded that the logistics alliances between hospitals have focus in the area of medical supplies and medicines, through the development of lending activities, exchanges and assignments, and negotiation and joint purchasing. These relationships can provide gains in material flows, drugs and information, consequently better results in terms of cost, quantity, time, place and quality, influencing the performance level of service delivery and emergency care to patient.

The objectives of this study are two-fold: (a) to delineate the factors that guide Ontario social workers’ decision-making when rendering judgments on the mandatory reporting of child maltreatment and (b) to understand how social workers maintain the therapeutic alliance with children and families following the decision to report suspected child maltreatment. The study is informed by two distinct bodies of literature: the decision-making theoretical literature within the fields of medicine, psychology, social work, and marriage and family therapy and the therapeutic alliance theoretical literature. Harnessing the advantages of online survey technology, the study surveyed registered members (n = 480) of the Ontario Association of Social Workers who provide direct service to children and families. Participants responded to prepared vignettes of suspected child maltreatment followed by Likert-scale questions (strongly agree to strongly disagree) and open-ended questions on strategies to maintain the alliance. Open-ended questions allowed respondents to offer further commentary regarding their opinions on mandatory reporting and on maintaining the therapeutic alliance. These comments added a rich source of information to the quantitative data. Multiple logistic regression analyses showed that social workers’ ethical responsibility to the College of Social Workers and Social Service Workers, their legal responsibility to the provincial mandatory reporting laws of Ontario, and consultation with peers or eliciting direction from a supervisor comprised the main factors in their decision-making around reporting suspected child maltreatment to the Children’s Aid Society. Qualitative analyses showed that social workers employ a plethora of strategies to repair the alliance following a disclosure of child maltreatment including reporting strategies, information strategies, affect regulation strategies, advocacy strategies, and resource strategies. The major limitation of the research design was the use of vignette research, which in proscribed circumstances may not reflect what the social worker does in actual practice. Design features that compensate for this limitation include (1) use of a 5-point Likert-item response of strongly agree to strongly disagree to allow respondents a range of responses; and (2) use of open-ended questions to allow respondents the opportunity to express their opinions on the issues.
