Analysis of extreme events in the Caribbean 1990-2008

This study presents an analysis of extreme events in the Caribbean subregion for the period 1990 to 2008, and forms part of a similar, wider study focused on the Latin America and the Caribbean region (Central America and South America being the other two subregional components). It explores the economic costs of climate change through an examination of adaptation costs to extreme events. ECLAC, through its Subregional Headquarters for the Caribbean, is pleased to have been able to undertake this study with the financial support of DFID and to have ensured its successful execution in collaboration with technical expertise from the University of the West Indies.

Setting boundaries: Environmental and spatial effects on Odonata larvae distribution (Insecta)

Características ambientais e distâncias espaciais entre os locais foram utilizadas para explicar a distribuição das espécies no ambiente, através das predições da teoria Neutra (espaço) e teoria do Nicho (ambiente). Foram avaliados os efeitos de fatores geográficos e ambientais sobre a distribuição de larvas de Odonata ao longo da Bacia do Rio Suiá-Missu, no estado de Mato Grosso. Nós testamos a hipótese de que (1) o ambiente é o principal fator de estruturação da comunidade devido às suas exigências ecofisiológicas; e (2) o padrão, se presente, é mais expressivo para Zygoptera. As amostras foram feitas em 12 locais na Bacia do Rio Suiá-Missu, em três campanhas (2007/2008), com um total de 1.382 larvas de Odonata, composta por 10 famílias, 51 gêneros e 100 morfoespécies. Os Anisoptera foram mais abundantes que Zygoptera, que compreende 81% de todas as amostras. O ambiente afetou Zygoptera (R = 0,291; p = 0,007) e foi o principal fator de estruturação da assembléia. Assim, a teoria do nicho foi confirmada. A ausência deste efeito sobre Anisoptera pode ser devido às adaptações ecofisiológicos que lhes permitem ocupar diferentes habitats. Larvas de Zygoptera são indicadores de mudanças na estrutura do habitat. Os efeitos das variáveis ambientais sobre a ecologia das larvas enfatizam a forte relação entre esses organismos e integridade ambiental.

Emerging powers, humanitarian assistance and foreign policy: the case of Brazil during the earthquake crisis in Haiti

During the management of the crisis after the earthquake occurred in Haiti in 12 January 2010, Brazil played an important role on the efforts of humanitarian assistance. Based on bibliography and documents the paper presents the role played by Brazil with the focus on the humanitarian assistance as part of country’ foreign policy as an emerging power to increase the presence into the international system. To achieve this goal the article presents some considerations about emerging powers, foreign policy and theoretical concepts about humanitarian assistance and international relations, the extension of the earthquake in Haiti and the actions performed by Brazil during the response phase of the crisis management.

O regime de metas inflacionárias e sua adequação à economia brasileira

The Inflation Targeting Regime was adopted in Brazil in 1999 and it aims at maintaining the price level in the interval set by the government. For such reason, the Central Bank makes use of variations in the interest rate, which causes the cost of the credit to be more expensive, reducing the investments, the jobs and, concomitantly, the inflation. Being aware that the country is subject to sudden reversals of the international capital flows which results in exchange rate and price instability, an econometric analysis of the adequation of the targerting regime to the Brazilian economy, especially concerned with the index price that is used as the parameter for the inflation calculus, is proposed

O perdão como componente moral em crianças do primeiro ano do ensino fundamental

Forgiveness may be considered a moral component to be developed along with the development of moral autonomy of individuals. This study aims to verify how 10 (ten) children from the first year of elementary school conceive the pardon and its possible relationship with their moral autonomy development. As theoretical research we have taken Piaget´s studies on human´s morality (1930; 1932) and Rique (2007, 2008, 2011) and Enright (1991, 1998) studies about forgiveness. This study was based on a qualitative research and the adopted method was the Piaget's Experimental Clinical Method. The results have shown that children perform moral reasoning when facing situations which involve the decision of forgiving someone and tend to comprehend forgiveness as forgiving someone for some performed act. We conclude by emphasizing the importance of the teacher’s mediation and intervention in moral discussions involving forgiveness, for the construction of the learners ´moral autonomy.

Exercise tolerance can be enhanced through a change in work rate within the severe intensity domain: work above critical power is not constant

The characterization of the hyperbolic power-time (P-tlim) relationship using a two-parameter model implies that exercise tolerance above the asymptote (Critical Power; CP), i.e. within the severe intensity domain, is determined by the curvature (W') of the relationship. The purposes of this study were (1) to test whether the amount of work above CP (W>CP) remains constant for varied work rate experiments of high volatility change and (2) to ascertain whether W' determines exercise tolerance within the severe intensity domain. Following estimation of CP (208 ± 19 W) and W' (21.4 ± 4.2 kJ), 14 male participants (age: 26 ± 3; peak [Formula: see text]: 3708 ± 389 ml.min-1) performed two experimental trials where the work rate was initially set to exhaust 70% of W' in 3 ('THREE') or 10 minutes ('TEN') before being subsequently dropped to CP plus 10 W. W>CP for TEN (104 ± 22% W') and W' were not significantly different (P>0.05) but lower than W>CP for THREE (119 ± 17% W', P<0.05). For both THREE (r = 0.71, P<0.01) and TEN (r = 0.64, P<0.01), a significant bivariate correlation was found between W' and tlim. W>CP and tlim can be greater than predicted by the P-tlim relationship when a decrement in the work rate of high-volatility is applied. Exercise tolerance can be enhanced through a change in work rate within the severe intensity domain. W>CP is not constant.

Índices climáticos e infestação predial por larvas de Aedes aegypti (Linnaeus, 1762) e Aedes albopictus (Skuse, 1894) em Araçatuba-sp Brasil

Aedes is synanthropic; associated with climatic conditions and urban environment. This study performed a retrospective evaluation of the climatic indices and the A. aeypti and A. albopictus infestation larvae rates (IP), registered from the month of October, 2005 to 2009, in the Araçatuba city, São Paulo State. There was no variation in the average temperature in the period (26.3°C). The rain falls were high in 2005 (133.5 mm3 ) fell in 2006, 2007 and 2008 (55.0 mm3 , 78.5 mm3 and 79.0 mm3 , respectively) and increased in 2009 (104.0 mm3 ). The infestation IP was 1.10, 1.39, 0.36, 0.28 and 3.30, respectively in 2005, 2006, 2007, 2008 and 2009, none of them were A. albopictus larvae. There was no association between IP and temperature, but there was significant difference (P <0.001) between the IP of 2009, with the IP of 2007 and 2008. This study it was concluded that among the environmental factors just rain influenced the rate of larvae, "infestation", committed only by A. aegypti.

The other Gulf oil crisis - in Southwest Asia

The oil spill in the Gulf of Mexico is a rude reminder of the risks inherent in an economy dependent upon petroleum. But there's a quieter crisis in the other gulf - the Persian Gulf - that should call Americans' attention to the even more severe consequences of relying upon imported oil. The costs of using the military to protect the transport of oil from the most turbulent part of the world should convince our country's policymakers to increase investments in researching and developing affordable, American-made clean-burning alternative fuels. But, first, we have to understand the real causes, costs and consequences of importing 12.9 million barrels of oil per day, which make up nearly 60 percent of U.S. oil consumption at a total direct cost of roughly $300 billion per year.

A Reappraisal in Sao Paulo, Brazil (2008) of "The Ecology of Medical Care:" The "One Per Thousand's Rule"

BACKGROUND AND OBJECTIVES: Medical ecology is a conceptual framework introduced in 1961 to describe the relationship and utilization of health care services by a given population. We applied this conception to individuals enrolled in a private health maintenance organization (HMO) in Sao Paulo, Brazil, with the aim of describing the utilization of primary health care, verifying the frequency of various symptoms, and identifying the roles of different health care sources. METHODS: This was a cross-sectional telephone survey among a random sample of people enrolled in a private HMO. We interviewed a random sample of non-pregnant adults over age 18 using 10 questions about symptoms and health care use during the month prior to interview. RESULTS: The final sample consisted of 1,065 participants (mean age 68 years, 68% female). From this sample, 424 (39.8%) reported the presence of symptoms, 311 (29.2%) had a medical office consult, 104 (9.8%) went directly to an emergency medical department, 63 (5.9%) were hospitalized, 22 (2.1%) used complementary medicine resources, seven (0.7%) were referred to home care, and one (0.1%) was admitted to an academic hospital. CONCLUSIONS: The proportion of study participants referred to an academic care center was similar to that observed in previous "medical ecology" studies in different populations.

Respiratory diseases and associated factors: population-based study in Sao Paulo, Brazil, 2008-2009

OBJECTIVE: To assess the prevalence of acute bronchitis, rhinitis, and sinusitis among children and adolescents and identify associated factors. METHODS: This is a population-based, cross-sectional study. A household survey was conducted with 1,185 children and adolescents from the city of Sao Paulo (Southeastern Brazil), from 2008 to 2009. The participants were selected by means of probability sampling, stratified by sex and age, and by two-stage cluster sampling. For the adjusted analysis, multiple Poisson regression was used. RESULTS: Of the respondents, 7.3% reported acute bronchitis, 22.6% rhinitis and 15.3% sinusitis. After the adjusted analysis, the following characteristics were associated with self;reported acute bronchitis: age 0 to 4 years (PR=17.86; 95%Cl: 3.65;90.91), 5 to 9 years (PR=37.04; 95%CI: 8.13;166.67), 10 to 14 years (PR.=20,83; 95%Cl: 4.93;90.91), allergy (PR=3.12; 95%Cl: 1.70;5.73), black and mixed-ethnicity (black and white) skin color (PR=2.29; 95%Cl: 1.21;4.35), and living in a household with 1 to 3 rooms (PR=1.85; 95%Cl: 1.17;2.94). As to self-reported rhinitis, the following characteristics were associated: age 10 to 14 years (PR=2.77; 95%Cl: 1.60;4.78), 15 to 19 years (P.R=2.58; 95%Cl: 1.52;4.39), allergy (PR=4.32; 95%Cl: 2.79;6.70), asthma (PR=2.30; 95%CI: 1.30;4.10) and living in flats (PR=1.70; 95%Cl: 1.06;2.73). Concerning self-reported sinusitis, the following characteristics were associated: age 5 to 9 years (PR=2.44; 95%Cl: 1.09;5.43), 10 to 14 years (PR=2.99; 95%CI: 1.36;6.58), 15 to 19 years (PR=3.62; 95%Cl: 1.68;7.81), allergy (PR=2.23 (95%CI: 1.41;3.52) and obesity (PR=4.42; 95%Cl: 1.56;12.50). CONCLUSIONS: Respiratory diseases were more prevalent in population groups with defined characteristics, such as age group, self-reported diseases, type of household and obesity.
