The relevance of subsidiary initiatives for Brazilian multinationals

The purpose of this paper is to analyze relationship patterns between headquarters and subsidiaries of Brazilian Multinationals Enterprises (BrMNEs). The key construct for that investigation is Subsidiary Initiative, which comprises Subsidiary Entrepreneurial Orientation, Autonomy, Integration, Local Competitive Context and Business Network. A survey was carried out in a sample of 65 subsidiaries of 29 BrMNEs. The main outcome is that subsidiaries are highly integrated and receive Entrepreneurial Orientation from Headquarters (HQs), but Initiative is limited. Actually, the main determinants of subsidiary's initiatives are Local Context and Business Networking in the host country. This apparent paradox may be explained by what we call 'rebellious subsidiaries', which take initiatives based on their business environment and connections, regardless of their HQs' directions or delegation of autonomy.

Infant mortality and low birth weight in cities of Northeastern and Southeastern Brazil

OBJECTIVE: To compare estimates of low birth weight (LBW), preterm birth, small for gestational age (SGA), and infant mortality in two birth cohorts in Brazil. METHODS: The two cohorts were performed during the 1990s, in São Luís, located in a less developed area in Northeastern Brazil, and Ribeirão Preto, situated in a more developed region in Southeastern Brazil. Data from one-third of all live births in Ribeirão Preto in 1994 were collected (2,839 single deliveries). In São Luís, systematic sampling of deliveries stratified by maternity hospital was performed from 1997 to 1998 (2,439 single deliveries). The chi-squared (for categories and trends) and Student t tests were used in the statistical analyses. RESULTS: The LBW rate was lower in São Luís, thus presenting an epidemiological paradox. The preterm birth rates were similar, although expected to be higher in Ribeirão Preto because of the direct relationship between preterm birth and LBW. Dissociation between LBW and infant mortality was observed, since São Luís showed a lower LBW rate and higher infant mortality, while the opposite occurred in Ribeirão Preto. CONCLUSIONS: Higher prevalence of maternal smoking and better access to and quality of perinatal care, thereby leading to earlier medical interventions (cesarean section and induced preterm births) that resulted in more low weight live births than stillbirths in Ribeirão Preto, may explain these paradoxes. The ecological dissociation observed between LBW and infant mortality indicates that the LBW rate should no longer be systematically considered as an indicator of social development.

O metacinema norte-americano e o storytelling : de Orson Welles a David Lynch

ABSTRACT: The American metacinema which, by tradition, is narrative but extremely formulaic favours the story above the telling. No man contributed more to alter this state of affairs than Orson Welles, whose cinematic practice exalted the filmic enunciation and linked it more explicitly to the narrative intentions of the creator, making it obvious that metanarrative is synonymous with metacinema. With Citizen Kane (1941), in particular, the cinema was made more disnarrative, as meant by French writer/director Alain Robbe–Grillet, well ahead of Modernism. The fragmented narration, the temporal convolutions, a tendency for paradox and the interpretative obstacles all come together to anticipate the serial practice of David Lynch in his last four features. Structuring the films in segments which constitute different but complementary versions of the same events, Lynch manages to express the director’s enunciation along with the narration of the characters, reinforcing the role of the telling in the midst of the story. In INLAND EMPIRE (2006) the use of mise-en-abyme as a way of duplicating stories and tellers further increases the objective and complicates what is clearly the reign of the puzzle or mind-game film. In the footsteps of Welles, Lynch contributed for an outbreak of metanarrative / metacinematic crossover indie films closer to the European aesthetic practice but still very much within the American narrative tradition.

Teatro no currículo: avaliar o quê e para quê?

Nalgumas áreas curriculares disciplinares, como o Teatro, as aprendizagens e as competências não se adquirem nem desenvolvem, em geral, de acordo com a díade de estratégias que os professores parecem privilegiar, isto é: transmissão do conhecimento e, pouco depois, confirmação – na maioria das vezes através da modalidade de escrita – da aprendizagem desse conhecimento pelos alunos. Note-se, porém, que, mesmo naquelas áreas que os responsáveis políticos distinguem com um “exame nacional”, como o Português, nem todas as aprendizagens promovidas e realizadas são testáveis numa prova escrita e no imediato (como, a título de exemplo, as que se inscrevem nos domínios da comunicação oral e da leitura em voz alta, também amplamente abordadas em Teatro). Às áreas da educação artística, e do Teatro em particular, os professores associam essencialmente – ou exclusivamente – a criatividade, a imaginação e a expressividade. Sendo, embora, competências potencialmente desenvolvidas e avaliadas também nas áreas da educação artística, não são um exclusivo destas áreas. Cada área curricular disciplinar do âmbito da educação artística – e o Teatro não é exceção – assenta numa específica linguagem artística, que integra conteúdos, estratégias, atividades, recursos, técnicas, conceitos e terminologias próprios, que as crianças, com vista ao seu desenvolvimento completo e harmonioso, têm o direito de aprender e desenvolver. Daqui decorrem algumas questões: O que – e como – avaliar nas áreas da educação artística, em particular no Teatro? Que princípios poderão estar inerentes a um dispositivo de avaliação em Teatro, em contexto curricular? Terão as modalidades de avaliação não escrita estatuto de fiabilidade? O binómio teatro/currículo encerra um paradoxo a que pretendemos dar atenção: embora nem sempre abordado com regularidade e seguindo uma lógica dedesenvolvimento curricular, o Teatro constitui, apesar disso, uma das estratégias privilegiadas pelos professores de participação em projetos e iniciativas formais, na maior parte das vezes de cariz pontual (como momentos festivos ou de apresentação à comunidade), em que os alunos são sujeitos ao juízo avaliativo dos públicos. Partindo dos princípios de que (i) em contexto curricular cada atividade tem uma intencionalidade e que (ii) a “educação” artística não visa a identificação ou a valorização de “talentos”, pretendemos defender a seguinte ideia: Só depois de estabelecermos inequivocamente os objetivos da nossa ação educativa-pedagógica e, por conseguinte, uma estratégia de avaliação, é que podemos definir um percurso com sentido. Esta comunicação de natureza teórica, cuja base reflexiva decorre de mais de vinte anos de intervenção em contextos escolares, tanto do ensino básico como de formação de professores, tentará formular questões e problematizar algumas linhas de pensamento, mais do que encontrar respostas, no sentido de suscitar, principalmente da parte dos professores, a necessidade de uma mudança de atitude e de práticas face ao teatro na escola.

Proteomic analysis of the influence of the adipocyte secretome on Glioma Gl261 cells

Glioma is the most frequent form of malignant brain tumor in the adults and childhood. There is a global tendency toward a higher incidence of gliomas in highly developed and industrialized countries. Simultaneously obesity is reaching epidemic proportions in such developed countries. It has been highly accepted that obesity may play an important role in the biology of several types of cancer. We have developed an in vitro method for the understanding of the influence of obesity on glioma mouse cells (Gl261). 3T3-L1 mouse pre-adipocytes were induced to the maturity. The conditioned medium was harvested and used into the Gl261 cultures. Using two-dimension electrophoresis it was analyzed the proteome content of Gl261 in the presence of conditioned medium (CGl) and in its absence (NCGl). The differently expressed spots were collected and analyzed by means of mass spectroscopy (MALDI-TOF-MS). Significantly expression pattern changes were observed in eleven proteins and enzymes. RFC1, KIF5C, ANXA2, N-RAP, RACK1 and citrate synthase were overexpressed or only present in the CGl. Contrariwise, STI1, hnRNPs and phosphoglycerate kinase 1 were significantly underexpressed in CGl. Aldose reductase and carbonic anhydrase were expressed only in NCGl. Our results show that obesity remodels the physiological and metabolic behavior of glioma cancer cells. Also, proteins found differently expressed are implicated in several signaling pathways that control matrix remodeling, proliferation, progression, migration and invasion. In general our results support the idea that obesity may increase glioma malignancy, however, some interesting paradox finding were also reported and discussed.

Visceral leishmaniasis in Brazil: revisiting paradigms of epidemiology and control

In the last 20 years, despite the known underestimation of cases, Brazil registered a marked increase in the incidence of visceral leishmaniasis. The main goal of this review is to reflect on some aspects of this zoonosis in Brazil and also to encourage the discussion in order to find more viable, effective and affordable strategies to be implemented by the Brazilian Leishmaniasis Control Program. The current situation of visceral leishmaniasis in Brazil might be seen as a paradox: the most important aspects of the disease are known, but so far the control of this disease has not yet been achieved. The current control strategies have not been able to prevent the geographical expansion, and even a rise in the incidence and lethality of visceral leishmaniasis. There is a need not only for a better definition of priority areas, but also for the implementation of a fieldwork monitoring system to the disease surveillance that could permit a further evaluation of the control program in areas where visceral leishmaniasis is endemic.

Structuring for glocalization

Globalization and localization seem to be opposite concepts – a thesis and its antithesis. Nonetheless, managers seem to be able to handle the paradox posed by these two contradicting tensions by enacting, via action, a synthesis that allows for the co-presence of a high level of global integration and local adaptation (instead of a compromise between both), which has been labeled glocalization. We discuss how the concept of improvisation allows this synthesis by developing the two poles that ground it, namely ‘glocal’ strategy and ‘glocal’ organization. Global advantage requires a dialectical capability that organizations rarely achieve, and the importance of which orthodox management theory rarely recognizes.

Ressocialização no meio prisional

This paper examine the purpose of rehabilitation while main purpose of imprisonment application, and the divergence between its central role assumed in legislation and what is being practiced in the institutional dimension. This study aims to determine the expected outcome of this dialectical opposition, in pursuit of preventive purposes that guide the criminal reactions of Portuguese criminal - legal system. To this end, the sentence of imprisonment shall be framed in the main politico- criminal traits of our country, analyzing the standards and principles that underlie and underpin our legal – criminal system. The guiding principles of the prison sentence and the respective legislation will be presented, such as the prison system and treatment provided to achieve the above desideratum. Finally material factors and legislative contradictions that oppose the rehabilitation in prisons will be presented. The dissertation does not intend to expose the solution to this paradox insurmountable, but rather present the main factors that hinder the achievement of the objectives intended to be achieved with the prison sentence.

Essays on bounded rationality: Individual decision and strategic interaction

Economics is a social science which, therefore, focuses on people and on the decisions they make, be it in an individual context, or in group situations. It studies human choices, in face of needs to be fulfilled, and a limited amount of resources to fulfill them. For a long time, there was a convergence between the normative and positive views of human behavior, in that the ideal and predicted decisions of agents in economic models were entangled in one single concept. That is, it was assumed that the best that could be done in each situation was exactly the choice that would prevail. Or, at least, that the facts that economics needed to explain could be understood in the light of models in which individual agents act as if they are able to make ideal decisions. However, in the last decades, the complexity of the environment in which economic decisions are made and the limits on the ability of agents to deal with it have been recognized, and incorporated into models of decision making in what came to be known as the bounded rationality paradigm. This was triggered by the incapacity of the unboundedly rationality paradigm to explain observed phenomena and behavior. This thesis contributes to the literature in three different ways. Chapter 1 is a survey on bounded rationality, which gathers and organizes the contributions to the field since Simon (1955) first recognized the necessity to account for the limits on human rationality. The focus of the survey is on theoretical work rather than the experimental literature which presents evidence of actual behavior that differs from what classic rationality predicts. The general framework is as follows. Given a set of exogenous variables, the economic agent needs to choose an element from the choice set that is avail- able to him, in order to optimize the expected value of an objective function (assuming his preferences are representable by such a function). If this problem is too complex for the agent to deal with, one or more of its elements is simplified. Each bounded rationality theory is categorized according to the most relevant element it simplifes. Chapter 2 proposes a novel theory of bounded rationality. Much in the same fashion as Conlisk (1980) and Gabaix (2014), we assume that thinking is costly in the sense that agents have to pay a cost for performing mental operations. In our model, if they choose not to think, such cost is avoided, but they are left with a single alternative, labeled the default choice. We exemplify the idea with a very simple model of consumer choice and identify the concept of isofin curves, i.e., sets of default choices which generate the same utility net of thinking cost. Then, we apply the idea to a linear symmetric Cournot duopoly, in which the default choice can be interpreted as the most natural quantity to be produced in the market. We find that, as the thinking cost increases, the number of firms thinking in equilibrium decreases. More interestingly, for intermediate levels of thinking cost, an equilibrium in which one of the firms chooses the default quantity and the other best responds to it exists, generating asymmetric choices in a symmetric model. Our model is able to explain well-known regularities identified in the Cournot experimental literature, such as the adoption of different strategies by players (Huck et al. , 1999), the inter temporal rigidity of choices (Bosch-Dom enech & Vriend, 2003) and the dispersion of quantities in the context of di cult decision making (Bosch-Dom enech & Vriend, 2003). Chapter 3 applies a model of bounded rationality in a game-theoretic set- ting to the well-known turnout paradox in large elections, pivotal probabilities vanish very quickly and no one should vote, in sharp contrast with the ob- served high levels of turnout. Inspired by the concept of rhizomatic thinking, introduced by Bravo-Furtado & Côrte-Real (2009a), we assume that each per- son is self-delusional in the sense that, when making a decision, she believes that a fraction of the people who support the same party decides alike, even if no communication is established between them. This kind of belief simplifies the decision of the agent, as it reduces the number of players he believes to be playing against { it is thus a bounded rationality approach. Studying a two-party first-past-the-post election with a continuum of self-delusional agents, we show that the turnout rate is positive in all the possible equilibria, and that it can be as high as 100%. The game displays multiple equilibria, at least one of which entails a victory of the bigger party. The smaller one may also win, provided its relative size is not too small; more self-delusional voters in the minority party decreases this threshold size. Our model is able to explain some empirical facts, such as the possibility that a close election leads to low turnout (Geys, 2006), a lower margin of victory when turnout is higher (Geys, 2006) and high turnout rates favoring the minority (Bernhagen & Marsh, 1997).

The value creation radar applied to the space engineering sector

This case study illustrates the application of the Value Creation Radar (VCR) to SenSyF, an Earth Observation (EO) system which was developed by Deimos Engenharia S.A. (DME), the Portuguese affiliate of Elecnor Deimos. It describes how a team of consultants adopted the VCR in order to find new market applications for SenSyF, selected the one with the highest potential, and defined a path to guarantee a sustainable market launch. This case study highlights the main challenges of bringing a technology-driven company closer to the market in the pursuit of long-term sustainability, while not compromising its technological capabilities

Towards a knowledge society

Economies are moving towards competitive stadiums based on knowledge and innovation. The changing environment and the level of globalization demand important efforts in order to sustain competitive advantages. Portugal has experienced a remarkable evolution since its adhesion to the European Union in several fields: economic development, Research & Development (R&D) consolidation, health parameters and social cohesion. As other developed economies, Portugal started its journey towards a knowledge-based economy and has been consolidating an innovation system during the last 35 years. The following report aims to analyze the evolution of a system since its creation to its last transformation within a globalized context. Challenges such as the lack of maturity of the system, the economic crisis, the European paradox, and closing the gap with other European countries are addressed in the next chapters. Likewise, recommendations on these points are provided by the end of the report as potential solutions.
