Political leadership and the politics of performance:France, Syria and the chemical weapons crisis of 2013

This article draws upon developments in UK research on political rhetoric and political performance in order to examine the incident in 2013 when French President François Hollande committed French forces to a US-led punitive strike against Syria, after the use of chemical weapons in a Damascus suburb on 21 August. The US-led retaliation did not take place. This article analyses Hollande's declaration on 27 July and his TV appearance on 15 September. His rhetoric and style are best understood as generic to the nature of the presidential office of the Fifth Republic. The article concludes by appraising how analysis of the French case contributes to the developing literature on rhetoric, celebrity and performance.

The Weapons of Mass Destruction and the Global Security Strategy of the EU

The proliferation of weapons of mass destruction (WMD), nuclear, biological and chemical (NBC) is one of the main security challenges facing the international community today. However the new Global Security Strategy of 2016 raises the question of non-proliferation of WMD only as an incidental matter, not addressing directly the threat, a fundamental threat in the regional and global security. This is a clear step backwards for the European common security.

Nonlethal, Attenuated, Transfusion-Associated Graft-Versus-Host Disease in an Immunocompromised Child: Case Report and Review of the Literature

Transfusion-associated graft-versus-host disease (TA-GVHD) is a rare complication of transfusion of nonirradiated blood components. It usually affects children in high-risk groups, including those who have primary immunodeficiencies (PIDs). It usually presents with skin, hepatic, digestive, and hematologic involvement and is normally fatal.

New weapons to fight old enemies: novel strategies for the (bio)control of bacterial biofilms in the food industry

Biofilms are microbial communities characterized by their adhesion to solid surfaces and the production of a matrix of exopolymeric substances, consisting of polysaccharides, proteins, DNA and lipids, which surround the microorganisms lending structural integrity and a unique biochemical profile to the biofilm. Biofilm formation enhances the ability of the producer/s to persist in a given environment. Pathogenic and spoilage bacterial species capable of forming biofilms are a significant problem for the healthcare and food industries, as their biofilm-forming ability protects them from common cleaning processes and allows them to remain in the environment post-sanitation. In the food industry, persistent bacteria colonize the inside of mixing tanks, vats and tubing, compromising food safety and quality. Strategies to overcome bacterial persistence through inhibition of biofilm formation or removal of mature biofilms are therefore necessary. Current biofilm control strategies employed in the food industry (cleaning and disinfection, material selection and surface preconditioning, plasma treatment, ultrasonication, etc.), although effective to a certain point, fall short of biofilm control. Efforts have been explored, mainly with a view to their application in pharmaceutical and healthcare settings, which focus on targeting molecular determinants regulating biofilm formation. Their application to the food industry would greatly aid efforts to eradicate undesirable bacteria from food processing environments and, ultimately, from food products. These approaches, in contrast to bactericidal approaches, exert less selective pressure which in turn would reduce the likelihood of resistance development. A particularly interesting strategy targets quorum sensing systems, which regulate gene expression in response to fluctuations in cell-population density governing essential cellular processes including biofilm formation. This review article discusses the problems associated with bacterial biofilms in the food industry and summarizes the recent strategies explored to inhibit biofilm formation, with special focus on those targeting quorum sensing.

Hypothermia during endotoxemic shock in female mice lacking inducible nitric oxide synthase

The present study was undertaken to evaluate: (1) whether lipopolysaccharide LPS-incluced hypothermic responses may be altered during two estrous cycle phases, proestrus and diestrus, and after ovariectomy, followed by hormonal supplementation and (2) whether nitric oxide (NO) plays a role on LPS-induced hypothermia responses in female mice. Experiments were performed on adult female wild-type (WT) C57BL and inducible NO synthase knockout (KO) mice weighing 18 to 30 g. Endotoxemia was induced by intraperitoneal LIPS administration from Escherichia coli at a nonlethal dose of 10 mg/kg, and body temperature was measured by biotelemetry. Hormonal replacement was performed in ovariectomized mice through 17 beta-estradiol Silastic capsules (100 mu g) and s.c. injection of progesterone (0.5 mg per animal). We observed that during the diestrus phase, mice presented more intensive hypothermia than during proestrus phase, and hormonal supplementation with 17 beta-estradiol and progesterone attenuated hypothermia in ovariectomized mice. During diestrus and ovariectomy, KO mice had higher hypothermic response when compared with the WT group. During proestrus, the lack of statistical difference between KO and WT mice could be consequent of lower ovarian hormones plasma levels. After hormonal replacement, hypothermia was reverted in KO groups probably because of higher ovarian hormonal levels. In summary, the results demonstrated that NO release by inducible NO synthase has an important thermoregulatory role in LPS-incluced hypothermia in female mice. Besides, this involvement is directly dependent on the presence of ovarian hormones and their respective levels.

Alcohol consumption in homicide victims in the city of Sao Paulo

Aims To assess the association between alcohol use and victimization by homicide in individuals autopsied at the Institute of Legal Medicine in Sao Paulo, Brazil. Design Cross-sectional study. Setting Excessive consumption of alcohol is a serious public health issue and a major factor in triggering violent situations, which suggests a strong association between alcohol ingestion and becoming a victim of homicide. Participants Data from 2042 victims of homicides in 2005 were obtained from medical examiner reports. Measurements The victim`s gender, age, ethnicity and blood alcohol concentration (BAC) were collected. The method of death and homicide circumstances, as well as the date, time and place of death were also studied. Findings Alcohol was detected in blood samples of 43% of the victims, and mean BAC levels were 1.55 +/- 0.86 g/l. The prevalence of positive BAC levels was higher among men (44.1%) than women (26.6%), P < 0.01. Firearms caused most of the deaths (78.6%), and alcohol consumption was greater among victims of homicide by sharp weapons (P < 0.01). A greater proportion of victims with positive BAC were killed at weekends compared to weekdays (56.4 and 38.5%, respectively; P < 0.01), and the correlation between homicide rates and the average BAC for the central area of the city was positive (r(s) = 0.90; P < 0.01). Conclusions These results highlight alcohol as a contributing factor for homicide victimization in the greatest urban center in South America, supporting public strategies and future research aiming to prevent homicides and violence related to alcohol consumption.

Role of regulatory T cells in long-term immune dysfunction associated with severe sepsis

Objective: To investigate the role of regulatory T cells in the modulation of long-term immune dysfunction during experimental sepsis. It is well established that sepsis predisposes to development of a pronounced immunosuppression. Nevertheless, the mechanisms underlying the immune dysfunction after sepsis are still not well understood. Design: Prospective experimental study. Setting: University research laboratory. Interventions: Wild-type mice underwent cecal ligation and puncture and were treated with antibiotic during 3 days after surgery. On days 1, 7, or 15 after cecal ligation and puncture, the frequency of regulatory T cells, proliferation of CD4(+) T cells and bacterial counts were evaluated. Fifteen days after cecal ligation and puncture, surviving mice underwent secondary pulmonary infection by intranasal inoculation of nonlethal dose of Legionella pneumophila. Some mice received agonistic glucocorticoid-induced tumor necrosis factor receptor antibody (DTA-1) before induction of secondary infection. Measurements and Main Results: Mice surviving cecal ligation and puncture showed a markedly increased frequency of regulatory T cells in thymus and spleen, which was associated with reduced proliferation of CD4(+) T cells. Fifteen days after cecal ligation and puncture, all sepsis-surviving mice succumbed to nonlethal injection of L. pneumophila. Treatment of mice with DTA-1 antibody reduced frequency of regulatory T cells, restored CD4(+) T cell proliferation, reduced the levels of bacteria in spleen, and markedly improved survival of L. pneumophila infection. Conclusion: These findings suggest that regulatory T cells play an important role in the progression and establishment of immune dysfunction observed in experimental sepsis.

Asian perceptions of BMD: Defence or disequilibrium?

As geopolitical competition between the United States and China intensifies, East Asian policy-makers are apprehensive about the Bush Administration's plans to develop ballistic missle defence (BMD). Missile defence threatens to undermine other fundamental assumptions aout nuclear weapons politics and arms control.

America's nuclear deterrence in the age of terrorism

The September 11, 2001 terrorist attacks in the US and the leakage of the Nuclear Posture Report (NPR) spur a complete review of the nuclear doctrine under Pres George W. Bush's administration. Kampmark discusses the contrariness of NPR in relation to America's deterrence of nuclear weapons and the possible proliferation of tactical offensive weapons as compared to strategic nuclear weapons.

Caenorhabditis elegans mutants resistant to phosphine toxicity show increased longevity and cross-resistance to the synergistic action of oxygen

Phosphine (hydrogen phosphide, PH3) is the fumigant most widely used to protect stored products from pest infestation. Despite the importance of this chemical, little is known about its mode of action. We have created three phosphine-resistant lines (pre-1, pre-7, pre-33) in the model organism C. elegans, with LC50 values 2, 5, and 9 times greater than the fully susceptible parental strain. Molecular oxygen was shown to be an extremely effective synergist with phosphine as, under hyperoxic conditions, 100% mortality was observed in wild-type nematodes exposed to 0.1 mg/l phosphine, a nonlethal concentration in air. All three mutants were resistant to the synergistic effects of oxygen in proportion to their resistance to phosphine with one mutant, pre-33, showing complete resistance to this synergism. We take the proportionality of cross-resistance between phosphine and the synergistic effect of oxygen to imply that all three mutants circumvent a mechanism of phosphine toxicity that is directly coupled to oxygen metabolism. Compared with the wild-type strain, all three mutants have an extended average life expectancy of from 12.5 to 25.3%. This is consistent with the proposed involvement of oxidative stress in both phosphine toxicity and ageing. Because the wild-type and mutant nematodes develop at the same rate, the longevity is unlikely to be caused by a clk-type reduction in oxidative metabolism, a potential alternative mechanism of phosphine resistance.

Para uma sócio-história da língua Guarani no Espírito Santo : uma análise sob a perspectiva sociolinguística

Estima-se que restam hoje cerca de 50 mil índios Guarani no Brasil, que se situam, principalmente, na faixa litorânea que vai desde os estados do sul até o território capixaba, o Espírito Santo. Considerando que essa comunidade se mantém bilíngue, o presente trabalho objetiva discutir se, na situação de contato entre o Guarani e o Português, a primeira língua está ou não cedendo lugar à segunda. Para alcançar esse objetivo, foi formado um banco de dados de fala por meio de entrevistas realizadas nas aldeias, que versaram sobre as tradições históricas, a família, a religião, a economia e o meio ambiente – aspectos considerados por eles como as principais armas de resistência desse povo. A análise tomou por base os pressupostos da Sociolinguística/Contato Linguístico, com teóricos como Weinreich (1953), Fishman (1968; 1972), Appel e Muysken (1996), Coulmas (2005) e outros, que discutem temas pertinentes à pesquisa em questão: o contato linguístico e a manutenção/substituição de línguas minoritárias. Acredita-se que, apesar do contato com o português pela venda de artesanatos, pela mídia e pela atuação da escola e sua ação integralizadora, prevista pelo Estatuto do Índio, o Guarani mantém a sua língua materna - ainda que estigmatizada - devido à forte religiosidade que norteia todo o seu modo de vida. Ele entende a palavra como um dom e confere a ela um poder mítico de conexão com o mundo espiritual, o que, ao mesmo tempo, confere extrema importância à língua minoritária e favorece a sua preservação, enquanto marca importante da cultura e identidade desse povo.

Leanness na manutenção aeronáutica: o caso FAP

Os sistemas de armas da Força Aérea Portuguesa (FAP) têm por missão a defesa militar de Portugal, através de operações aéreas e da defesa do espaço aéreo nacional, sendo o F-16 o principal avião de ataque em uso nesta organização. Neste sentido, e tendo em conta o actual contexto económico mundial, as organizações devem rentabilizar todos os recursos disponíveis, custos associados e optimizar processos de trabalho. Tendo por base os pressupostos anteriores, o presente estudo pretende analisar a implementação de lean na FAP, uma vez que esta filosofia assenta na eliminação de desperdícios com vista a uma melhoria da qualidade e diminuição de tempos e custos. Posto isto, a análise deste trabalho vai recair sobre a área de manutenção do F-16, em concreto na Inspeção de Fase (IF), um tipo de manutenção que esta aeronave realiza a cada trezentas horas de voo. O estudo de caso vai incidir em dois momentos da IF: o primeiro ponto relaciona-se com o processamento da recolha de dados para a reunião preliminar onde são definidas, para as áreas de trabalho executantes, as ações de manutenção a realizar com a paragem da aeronave. Deste modo, pretende-se averiguar as causas inerentes aos atrasos verificados para a realização desta reunião. O segundo ponto em observação compreende a informação obtida através da aplicação informática SIAGFA, em uso na FAP, para o processamento de dados de manutenção das quatro aeronaves que inauguraram a IF com a filosofia lean. Esta análise permitiu perceber o número de horas de trabalho dispendidas (em média pelas quatro aeronaves) por cada uma das cartas de trabalho, verificando-se que as cartas adicionais comportam mais horas; foi possível compreender quais as áreas de trabalho consideradas críticas; foram identificados os dias de trabalho realizado e tempos de paragem sem qualquer tipo de intervenção. Foi ainda avaliado, por aeronave, o número de horas de trabalho realizadas na IF e quais os constrangimentos que se verificaram nas aeronaves, que não realizaram a IF no tempo definido para tal.
