Book Description
This innovative volume introduces Trajectory Analysis, a new systems-based approach to measuring nonlinear dynamics in continuous change, to public health and epidemiology. It synthesizes influential strands of statistical and probability science (including chaos theory and catastrophe theory) to complement existing methods and models used in the health fields. The computational framework featured here pinpoints complex cause-and-effect processes in behavioral change as individuals and populations adjust to health interventions, with examples from neuroscience and cardiology. But this is no mere academic exercise, as the author illustrates how these methods can be harnessed toward finding real-world answers to longstanding public health problems, starting with treatment recidivism. Included in the coverage: · The universality of physical principles in the analysis of health and disease · The problem of recidivism in healthcare intervention studies · Stability and reversibility/irreversibility of health conditions · Chaos theory and sensitive dependence on initial conditions · Applications in health monitoring and geographic systems · Simulations, applications, and the challenge for public health A stimulating new take on statistics with powerful implications for future study, practice, and policy, Trajectory Analysis in Health Care should interest public health epidemiologists, researchers, clinicians, and policymakers.

Book Description
Technological cooperation is not only costly and time consuming, but also has a high attrition rate. Most literature on strategic cooperation focuses mainly on issues related to cooperation formation and the reasons why firms form these cooperative partnerships. However, a successfully formed cooperation is not always managed well enough to achieve a satisfactory performance. The knowledge of cooperative formation is necessary, but insufficient to achieve a satisfactory performance. The literature suggests that scholars know little about the underlying factors affecting cooperative performance. A comprehensive literature review was conducted to establish the possible effects of key factors on the performance of international technological cooperation, and the possible relations between key factors. A qualitative pilot study was implemented to verify the practical relevance of those 12 key factors, of which 6 factors have a relatively more significant effect on performance than the other 6 factors. By applying theoretical modeling techniques, the research framework was then constructed according to the postulated relations between 7 key factors (6 relatively more significant factors and the focal concept, performance). Strictly based on the definition of key factors, measurement items of each key factor were carefully reviewed and selected. Following the process of structural equation modeling, the structural equation model in this research was constructed. Unlike most previous cooperation studies, a structural equation model allows researchers to examine simultaneously all the relations amongst key factors. The data were collected from mangers who had experience in managing a technological cooperative project with foreign partners, and were then analyzed by LISREL, a longstanding and widely distributed structural equation modeling computer program. The result suggests that symmetric opinions, commitment, dependence, relationships, partner analyses, and rewards have effects on the performance of international technological cooperation, which confirms the results of the thorough and comprehensive literature review and of the qualitative pilot study. In addition, in the structural equation model of this research, relationships and rewards have effects on commitment, and partner analyses and rewards have effects on dependence, which are also consistent with the literature review. The findings have contributed to theory advancement in cooperation studies, and to the knowledge of international business. Managerial implications from the findings also provide advices, which managers can proactively take, to avoid the odds of success.

Book Description
An empirical study was undertaken (a) to examine the characteristics, influencing factors, and effectiveness of a distinctive Chinese management model adopted by the newly founded private enterprises in mainland China, as well as (b) to test the "fit" notion in contingency theory. The study was based on a random sample of 124 standardized personal interviews with CEOs of Chinese industrial and service companies in Beijing and Shanghai. The standardized questionnaire mainly contained the Aston structure scales (Pugh and Hickson 1976) and Khandwalla's (1977) management schedules. Besides, three case examples were studied including one state-owned bank and two private enterprises. Using AMOS structural equation modeling, size, mass-technology and uncertainty, as well as CEO need for achievement, environmental constraints and selected Chinese characteristics, were specified as influencing factors of "bureaucracy" and managerial practices, which included strategic orientation, leadership style, decision-making, communication and subcontracting. Another model analyzed the influence of various key success factors on organizational effectiveness. The findings provided support for the re-adoption of a distinctive Chinese management model in private companies, characterized by autocratic leadership, low formalization, "Chinese entrepreneurship" and network-based "webs". Private enterprises also tended to readopt and emphasize traditional Chinese family-related values. The distinctiveness of this model was, ceteris paribus, due to this emphasis on familism, which had a direct impact on organizational design and an indirect influence through its negative association with company size, which in turn significantly covaried with organizational design. This family-based ownership model was positively associated with organizational effectiveness. As regards contingency theory, the "traditional" fit hypotheses could not be rejected. In addition, less effective companies were not necessarily in "misfit". "Appropriate" structure, together with an optimizing planning style and firm age, were positively associated with performance. Managerial recommendations were codified in a CHINA(c) strategy framework for high effectiveness.

Book Description
Tant au niveau des revenus que du développement économique, les inégalités n'ont pas diminué dans le monde, en ce début du troisième millénaire ; et cela malgré les interventions des gouvernements, des ONG et des bailleurs de fonds internationaux. On commettrait également une grave erreur de diagnostic si l'on considérait la pauvreté et l'exclusion sociale comme des caractéristiques réservées aux pays en développement. Les inégalités dans la répartition du revenu et dans l'accès aux droits existent également dans les pays les plus riches. Les essais regroupés dans cet ouvrage entendent procéder à une étude aussi exhaustive que possible des rapports entre développement économique, égalité et pauvreté. Cette analyse est conduite dans le cadre de trois grands domaines thématiques. Le premier présente le cadre théorique de référence relatif aux interconnexions entre développement économique et inégalités. Le deuxième est consacré à l'étude de la pauvreté et de l'exclusion sociale dans les régions et pays en développement (Sahel, Maroc, Burkina Faso, Nigeria). Enfin, le troisième thème porte sur l'analyse des inégalités et de la pauvreté dans les pays développés, en particulier dans les zones urbaines de Rome, Naples, Munich, Dublin, aux fins d'une analyse comparative. Dans l'essai introductif Growth and Inegality. Theoretical Issues and Empirical Evidence, sont examinées les interconnections entre croissance économique et inégalités. Les auteurs procèdent ainsi à une revue critique, aussi vaste que minutieuse, de la littérature en la matière. Ils démontrent que l'examen des inégalités ne saurait être limité à la répartition du revenu mais qu'il faut également l'étendre à bien d'autres facteurs pour identifier les dimensions réelles du bien-être et des inégalités.

Book Description
Significantly revised, the fifth edition of the most complete, accessible text now covers all three approaches to structural equation modeling (SEM)--covariance-based SEM, nonparametric SEM (Pearl’s structural causal model), and composite SEM (partial least squares path modeling). With increased emphasis on freely available software tools such as the R lavaan package, the text uses data examples from multiple disciplines to provide a comprehensive understanding of all phases of SEM--what to know, best practices, and pitfalls to avoid. It includes exercises with answers, rules to remember, topic boxes, and a new self-test on significance testing, regression, and psychometrics. The companion website supplies helpful primers on these topics as well as data, syntax, and output for the book's examples, in files that can be opened with any basic text editor. New to This Edition *Chapters on composite SEM, also called partial least squares path modeling or variance-based SEM; conducting SEM analyses in small samples; and recent developments in mediation analysis. *Coverage of new reporting standards for SEM analyses; piecewise SEM, also called confirmatory path analysis; comparing alternative models fitted to the same data; and issues in multiple-group SEM. *Extended tutorials on techniques for dealing with missing data in SEM and instrumental variable methods to deal with confounding of target causal effects. Pedagogical Features *New self-test of knowledge about background topics (significance testing, regression, and psychometrics) with scoring key and online primers. *End-of-chapter suggestions for further reading and exercises with answers. *Troublesome examples from real data, with guidance for handling typical problems in analyses. *Topic boxes on special issues and boxed rules to remember. *Website promoting a learn-by-doing approach, including data, extensively annotated syntax, and output files for all the book’s detailed examples.
