1. Implementing strategies in complex systems: lessons from Brazilian hospitals
Hospitals, as social organizations, are seen as complex, surprising, ambiguous and paradoxical. The theoretical foundation finds its roots in organizational complexity, strategic management characterized by strategy implementation, and sensemaking especially in the context of complex adaptive systems. Managers frequently neglect elements of complexity when t

2. Modelagem e simulação de agentes com aspectos cognitivos para avaliação de comportamento social. / Modeling and simulation of agents with congnitive aspects to evaluate social behavior.
This work was developed considering concepts of four research areas: computer science, cognitive science, information science and social communication. The main contribution here is to define minimally cognitive agents who actively participate in dynamic of information flow interfering on the messages received and are being affected by them. The model consid

3. Are prices too sticky? The same question and the new achieved answers from the agent-based computational modeling / Os preços são muito rígidos? A mesma questão e as novas respostas encontradas através da modelagem computacional baseada em agentes
A moeda fiduciária permitiu o surgimento da política monetária e esta vêm ganhando cada vez mais destaque entre as ferramentas e políticas econômicas. Porém, não existe consenso no meio acadêmico sobre a influência da política monetária à economia, alguns acreditam que ela apenas resulta em variações nominais e outros que ela pode afetar fator

4. Análise de redes sociais em comunidades virtuais emergentes de jogos on-line por meio de coleta de dados automatizada
The current worldwide popularity of on-line games has resulted in the formation of virtual communities with hundreds of people. This is due to the daily interaction of people in games called Massive Multiplayer Online Role-Playing Games (MMORPGs). These communities are culturally diverse and permeated by social ties estabilished through different ways in the

5. Organizações e portfolios de projetos sob a perspectiva da Teoria da Complexidade. / Organization and project portfolios in a complexity theory approach.
Projects and portfolios play a central role in attaining an organizations strategic objectives, particularly within the recent scenarios of huge social, economic and technological change. With the professionalization of Project Management (PM), various methods and techniques came into use to plan and control activities aiming at the fulfillment of anticipate

6. Lupus eritematoso sistêmico: estudo qualitativo de mecanismos psicossociais adaptativos
Systemic Erithematous Lupus (SEL) is a serious disease with variable symptomatology, and whose aetiology is poorly known. It attacks conjunctive tissue in an inflammatory fashion, finally involving all the systems of the organism, simultaneously or sucessively, and is characterized by a wide variety of immunological abnormalities. SEL is included among the s

7. Schizophrenia: do men and women suffer from the same disease?
This article reviews the literature on normal brain development and behavioural development in men and women as well as on aetiological risk factors for schizophrenia, such as pre-, peri- and postnatal complications. The male-female comparisons of age and type of onset, symptomatology, course and outcome were based on a population-based sample of 232 first i

8. STRATEGIC PLANNING AND COMPLEX SOCIAL SYSTEMS: TWO CASES / PLANEJAMENTO ESTRATÉGICO E SISTEMAS SOCIAIS COMPLEXOS: DOIS CASOS / PLANEAMIENTO ESTRATÉGICO DE SISTEMAS SOCIALES COMPLEJOS DOS CASOS
Esta dissertação tem por objetivo um estudo comparativo do processo de planejamento estratégico de dois sistemas sociais complexos, as cidades do Rio de Janeiro e de Porto Alegre. Analisa-se a adequação das metodologias de planejamento empregadas nesses processos, em vista das características de cada um dos sistemas em estudo. Utiliza se como base para

9. An agent-based approach for modeling molecular self-organization
Agent-based modeling is a technique currently used to simulate complex systems in computer science and social science. Here, we propose its application to the problem of molecular self-assembly. A system is allowed to evolve from a separated to an aggregated state following a combination of stochastic, deterministic, and adaptive rules. We consider the probl

10. Calling for help is independently modulated by brain systems underlying goal-directed behavior and threat perception
In primates, during times of need, calling for help is a universal experience. Calling for help recruits social support and promotes survival. However, calling for help also can attract predators, and it is adaptive to inhibit calls for help when a potential threat is perceived. Based on this, we hypothesized that individual differences in calling for help w

11. The importance of being discrete: Life always wins on the surface
Many systems in chemistry, biology, finance, and social sciences present emerging features that are not easy to guess from the elementary interactions of their microscopic individual components. In the past, the macroscopic behavior of such systems was modeled by assuming that the collective dynamics of microscopic components can be effectively described col

12. Agent-based modeling as organizational and public policy simulators
Agent-based models are an increasingly powerful tool for simulating social systems because they can represent important phenomenon difficult to capture in other mathematical formalisms. But, agent-based models have provided only limited support for policy-making because their distinctive abilities are often most useful in situations where the future is unpre
