WE WERE SOLDIERS – Ein spätes Beispiel medialer/filmischer Sinnbildung in der Folge des amerikanischen Vietnamkrieges

Eine Analyse des Films „We were Soldiers“ von Randall Wallace. Strukturale Filmanalyse nach Faulstich. Die Filmanalyse setzt sich mit der filmischen Darstellungsweise des Vietnamkrieges auseinander. Dafür wird die Inszenierung der amerikanischen Gesellschaft, des US-Militärs, des nordamerikanischen Soldaten sowie der Medien besonders betrachtet. Grundlage der gesamten Arbeit ist ein für diese Analyse erstelltes Sequenzprotokoll, welches im Anhang zu finden ist.

Níveis críticos de fósforo em Brachiaria decunbens (Stapf) Prain, Brachiaria humidicola (Rendle) Schweickerdt, Digitaria decumbens Stent, Hypharrhenia rufa (Ness) Stapf, Melinis minutiflora Pal de Beauv, Panicum maximum Jacq. e Pennisetum purpureum Schum

Plantas dos capins braquiaria brachiaria decumbens Stapf (Prain) , quicuio da Amazonia, (Brachiaria humidicola (Rendle) Schweickerdt), pangola (Digitaria decumbens Stent), jaraguá (Hyphrrhenia rufa (Ness) Stapf), gordura (Melinis minutiflora Pal de Beauv), colonião (Panicum maximum Jacq) e napier (Pennisetwn purpure um Schum) foram cultivadas em solução nutritiva completa contendo, 0,12; 0,48; 1,94; 7,75 e 31,00 mg de fósforo por litro, com o objetivo de determinar os níveis críticos internos e externos de fosforo, e avaliar a eficiência com que absorvem e utilizam o fósforo. Aos setenta e cinco dias as plantas foram coletadas, separadas em caules, folhas, bainhas e raízes. Após secagem a 80ºC, as amostras foram pesadas e analisadas para fósforo na matéria seca. Curvas representativas do peso da matéria seca e da concentração de fósforo na matéria seca em função dos níveis de fosforo da solução nutritiva foram obtidas a partir de dados calculados de equações de regressão. Verificou-se que: - As espécies diferiram quanto à necessidade externa de fósforo, sendo B. humidicola e H. rufa as menos exigentes. Seguiram-se em ordem crescente B. decumbens, M. minutiflora, P. maximum, P. purpureum e D. decumbens. - Os níveis críticos internos de fósforo variaram entre as espécies, sendo maior em D. decumbens (0,38%) que nas demais. Seguiram-se em ordem decrescente B. decumbens (0,32%), B. humidioola (0,26%), M. minutiflora (0,24%), P. maximum (o,24%) e P. purpureum (0,20%). - A eficiência de absorção e utilização, do fósforo foi maior para B. humidicola. Seguiram-se em ordem decrescente P. purpureum, P. maximum, D. decumbens , B. decumbens e M. minutiflora.

The Phenomenon of international new ventures, global start-ups, and born-globals: what do we know after a decade (1993-2002) of exhaustive scientific inquiry?

In this paper, 27 studies from the last decade which deal more or less explicitly with the International New Venture, global start-up or born-global phenomenon are first identified, and then fully examined and critically assessed as a basis for obtaining an adequate view of the state-of-the-art of this increasingly important research avenue in the field of International Entrepreneurship (IE). The methodology used for this synthetic review allow us to analyze a number of recent, purposefully-chosen studies that are systematically compared along the following criteria: 1) main objective and type of research; 2) theoretical framework/s of reference, 3) methodological issues, and 4) main findings and/or conclusions. As a result of this literature review, a critical assessment follows in which the most relevant benefits and contributions as well as potential drawbacks, limitations or major discrepancies in the research activities conducted so far are discussed. Finally, some suggestions and implications are provided in the form of future research directions.

Sommes-nous prêts à prescrire une polypill à nos patients [Are we ready to prescribe a polypill to our patients?].

The all-in-one pill combination (Polypill) of several active components used in primary prevention of cardiovascular disease was a decade ago purposed to reduce the cardiovascular burden by more than 80%. This Polypill could be approved before 2013 in United States. Although controversed, it could answer to the worried situation even observed in Switzerland: the adherence to secondary prevention treatments is clearly insufficient and the cardiovascular events remain in the first row of death's causes. This abstract summarize the results from interventional studies who tried to valid this concept as well as the main stakes to be assessed on the medical side before to consider such a similar approach in Switzerland.

Adherence: the journey of medication taking, are we there yet?

Patient adherence to medications has been an issue challenging healthcare professionals for decades. Adherence rates, causes of non-adherence, barriers and enablers to medication taking, interventions to promote adherence, and the impact of non-adherence on health outcomes, have been extensively studied. In light of this, the area of adherence research has progressed conceptually and practically. This special issue contains a range of articles which focus on different aspects of adherence, from standardising terminology and methods of measurement, to non-adherence in a broad range of patient populations, and to interventions to promote adherence.

Physical activity attenuates the influence of FTO variants on obesity risk: a meta-analysis of 218,166 adults and 19,268 children.

BACKGROUND: The FTO gene harbors the strongest known susceptibility locus for obesity. While many individual studies have suggested that physical activity (PA) may attenuate the effect of FTO on obesity risk, other studies have not been able to confirm this interaction. To confirm or refute unambiguously whether PA attenuates the association of FTO with obesity risk, we meta-analyzed data from 45 studies of adults (n = 218,166) and nine studies of children and adolescents (n = 19,268). METHODS AND FINDINGS: All studies identified to have data on the FTO rs9939609 variant (or any proxy [r(2)>0.8]) and PA were invited to participate, regardless of ethnicity or age of the participants. PA was standardized by categorizing it into a dichotomous variable (physically inactive versus active) in each study. Overall, 25% of adults and 13% of children were categorized as inactive. Interaction analyses were performed within each study by including the FTO×PA interaction term in an additive model, adjusting for age and sex. Subsequently, random effects meta-analysis was used to pool the interaction terms. In adults, the minor (A-) allele of rs9939609 increased the odds of obesity by 1.23-fold/allele (95% CI 1.20-1.26), but PA attenuated this effect (p(interaction)  = 0.001). More specifically, the minor allele of rs9939609 increased the odds of obesity less in the physically active group (odds ratio  = 1.22/allele, 95% CI 1.19-1.25) than in the inactive group (odds ratio  = 1.30/allele, 95% CI 1.24-1.36). No such interaction was found in children and adolescents. CONCLUSIONS: The association of the FTO risk allele with the odds of obesity is attenuated by 27% in physically active adults, highlighting the importance of PA in particular in those genetically predisposed to obesity.

When is Monetary Policy All we Need?

We consider optimal monetary and scal policies in a New Keynesian model of a small open economy with sticky prices and wages. In this benchmark setting monetary policy is all we need - analytical results demonstrate that variations in government spending should play no role in the stabilization of shocks. In extensions we show, rstly, that this is even when true when allowing for in ation inertia through backward-looking rule-of-thumb price and wage-setting, as long as there is no discrepancy between the private and social evaluation of the marginal rate of substitution between consumption and leisure. Secondly, the optimal neutrality of government spending is robust to the issuance of public debt. In the presence of debt government spending will deviate from the optimal steady-state but only to the extent required to cover the deficit, not to provide any additional macroeconomic stabilization. However, unlike government spending variations in tax rates can play a complementary role to monetary policy, as they change relative prices rather than demand.

Génétique et hypertension artérielle: qu'avons nous-appris ? [Hypertension genetics: what have we learned so far?]

Hypertension is a common, modifiable and heritable cardiovascular risk factor. Some rare monogenic forms of hypertension have been described, but the majority of patients suffer from "essential" hypertension, for whom the underlying pathophysiological mechanism is not clear. Essential hypertension is a complex trait, involving multiple genes and environmental factors. Recently, progress in the identification of common genetic variants associated with blood pressure and hypertension has been made thanks to large-scale international collaborative projects involving geneticists, epidemiologists, statisticians and clinicians. In this article, we review some basic genetic concepts and the main research methods used to study the genetics of hypertension, as well as selected recent findings in this field.

Agglomeration and inequality across space: what can we learn from the European experience?

The purpose of this contribution is to draw a picture of the (uneven) distribution of economic activities across the states of the European Union (EU) and the consequences entailed by it. We will briefly summarize the most salient and recent contributions. Then, in the light of the economic geography theory, we will discuss the economic and social advantages and disadvantages associated with a core- periphery structure. In this sense, particular attention will be addressed to the EU financial system of Structural Funds and the effects they produced. Finally, we will formulate some suggestions, relying on the EU experience, that could be of interest to the current Brazilian regional policy.

When Do We Learn to Cooperate? The Role of Social Learning in Social Dilemmas

In this paper, I look at the interaction between social learning and cooperative behavior. I model this using a social dilemma game with publicly observed sequential actions and asymmetric information about pay offs. I find that some informed agents in this model act, individually and without collusion, to conceal the privately optimal action. Because the privately optimal action is socially costly the behavior of informed agents can lead to a Pareto improvement in a social dilemma. In my model I show that it is possible to get cooperative behavior if information is restricted to a small but non-zero proportion of the population. Moreover, such cooperative behavior occurs in a finite setting where it is public knowledge which agent will act last. The proportion of cooperative agents within the population can be made arbitrarily close to 1 by increasing the finite number of agents playing the game. Finally, I show that under a broad set of conditions that it is a Pareto improvement on a corner value, in the ex-ante welfare sense, for an interior proportion of the population to be informed.
