Elections and stock market volatility: evidence in OECD countries and developing countries

Este trabalho estuda se existe impacto na volatilidade dos mercados de ações em torno das eleições nacionais nos países da OCDE e nos países em Desenvolvimento. Ao mesmo tempo, pretende, através de variáveis explicativas, descobrir os fatores responsáveis por esse impacto. Foi descoberta evidência que o impacto das eleições na volatilidade dos mercados de ações é maior nos países em Desenvolvimento. Enquanto as eleições antecipadas, a mudança na orientação política e o tamanho da população foram os factores que explicaram o aumento da volatilidade nos países da OCDE, o nível democrático, número de partidos da coligação governamental e a idade dos mercados foram os factores explicativos para os países em Desenvolvimento.

Perfil da política e instrumentos de comércio internacional dos BICS: China, Índia e Brasil

Para os três integrante dos BICs, o comércio internacional tem representado prioridades diferentes nos seus modelos de crescimento. Para a China, por duas décadas, foi o elemento central da sua Política Econômica. Para a Índia e Brasil, a prioridade foi o desenvolvimento do mercado interno, via expansão da demanda e controle da inflação, sendo o comércio internacional elemento de ajuste. O perfil de participação dos três países na OMC – Organização Mundial de Comércio, também revela diferentes níveis de prioridades da Política de Comércio Internacional. A China, ao fazer do comércio seu eixo de desenvolvimento, tornou sua acessão à OMC, em 2001, item central da agenda externa. De outro lado, Índia e Brasil são partes fundadoras do antigo GATT e membros fundadores da OMC. Como a grande maioria dos membros da OMC, via no processo de acessão da China uma forma de criar regras para o comércio chinês. Ao longo da década passada, os três BICs assumiram posição de liderança na atual rodada de negociações, como defensores dos interesses dos PEDs – Países em Desenvolvimento. A atuação desses três países na OMC reflete os interesses que defendem, o que pode ser revelado na utilização dos instrumentos de política comercial. Apesar de parceiros estratégicos na OMC e nas negociações internacionais, China, Índia e Brasil têm interesses distintos e Políticas de Comércio Internacional diversas. O que chama a atenção do analista é a timidez do Brasil no uso de instrumentos de defesa comercial. Os dados demonstram que, apesar da intensidade do relacionamento entre China e Índia, a Índia não se esquivou de usar seus instrumentos de antidumping, medidas compensatórias e salvaguardas regulares e transitórias contra a China. Tais ações, por fazerem parte do jogo do comércio, não foram politizadas

Gestão pública de megaeventos esportivos no Brasil: a experiência paulistana na realização da Copa do Mundo FIFA

Esta pesquisa se propôs a investigar a gestão pública da 20ª edição da Copa do Mundo FIFA, realizada no Brasil em 2014. Contestada popularmente por milhares de brasileiros, o megaevento esportivo teve suas contradições, principalmente em relação aos altos gastos públicos e à lucrativa participação da Federação Internacional de Futebol (FIFA). Durante os seus preparativos e realização, aconteceu um dos mais duradouros ciclos de protestos da história recente do Brasil, o que destaca a insatisfação de muitos brasileiros em relação aos investimentos dos governos federal, estaduais e municipais para a sua realização. Com recorte mais aprofundado para a gestão do megaevento na cidade de São Paulo, o trabalho procurou compreender os acordos entre as partes e analisar a relação entre as instituições – a FIFA e os Governos – na operacionalização e decisões sobre o megaevento. Além disso, destaca as interfaces estabelecidas entre governos e a sociedade civil, em sua diversidade identificada empiricamente, e aprofunda nas inflexões das reivindicações populares e protestos na gestão do megaevento pela prefeitura paulistana. O estudo é um estudo de caso único e, portanto, foi realizado com métodos qualitativos de pesquisa. Foram utilizadas fontes múltiplas de coleta que possibilitaram a triangulação dos dados obtidos e o aumento da validade dos resultados. Foram feitas observações diretas durante os protestos e na região de impacto dos empreendimentos da Copa, coleta em documentos oficiais, legislações, atas, contratos e matérias jornalísticas e entrevistas com atores-chave dos governos federal e municipal, com ativistas e manifestantes, líderes comunitários e representantes de organizações da sociedade civil. A pesquisa apontou que os megaeventos esportivos são um importante tema de pesquisa pelo mundo e têm se revelado como uma relevante preocupação em países em desenvolvimento, além de terem se tornado um importante instrumento político para a promoção da imagem dos países-sede no exterior e para a projeção de partidos nos territórios nacionais. Seus resultados destacam a formação de campos antagônicos entre governos e sociedade civil e a formação de arenas de conflito também entre os atores sociais. Embora haja visto alguns esforços pela transparência da gestão, não se pode dizer que a Copa do Mundo no Brasil teve nível ideal de transparência, tampouco de participação social. Se por um lado houve esforços para se aprimorar a transparência, por outro, os canais de participação social instituídos não expressaram relevância para a gestão pública do megaevento. As interfaces entre governos e a sociedade civil foram identificadas, assim como seus efeitos e inflexões sobre a gestão do mundial. A principal interface destacada se deu no nível da rua e se afirmou na forma do enfrentamento entre manifestantes e a polícia. A segunda mais evidente se consolidou na negociação direta entre comunitários vulneráveis às obras da Copa e gestores municipais. Os efeitos dos protestos de rua sobre a ação dos governos se destacou na atividade policial, que usou a violência e a repressão como principais respostas ao conjunto de manifestações, e na criação de espaços de negociação direta com as comunidades, este influenciado mais diretamente pela formação de grupos de reivindicação, como o Comitê Popular da Copa, e pela resistência da própria comunidade. A gestão da Copa do Mundo no Brasil foi complexa e evidenciou, do ponto de vista das relações federativas, alguns problemas entre município, estado e União, que tratam da coordenação de programas, políticas ou ações, neste caso, um megaevento esportivo, de gestão compartilhada. O caso aponta dissonâncias e desalinhamentos entre governo federal, estadual e municipal sobre as práticas de diálogo, negociação, transparência e participação social. A pesquisa destaca a formação de um conjunto social mais atento, crítico e politizado, que reivindica, contesta e ocupa as ruas demonstrando sua insatisfação com governos, sistemas políticos e formas de representação. Aponta para resultados mais tangíveis e relações mais harmônicas entre governos e população quando são implementadas formas alternativas de participação e envolvimento social, sobretudo espaços e processos em que há lugar para a negociação e inserção da sociedade civil nos processos decisórios

The research that resulted in the articles is within the scope of the project entitled “Windows of opportunities and knowledge networks: implications for catch-up in developing countries”, funded by Support Programme for Research and Academic Production of Faculty (ProPesquisa) of Brazilian School of Public and Business Administration (EBAPE) of Getulio Vargas Foundation.

Cross-border reverse takeover: o caso das multinacionais brasileiras

O Cross-border reverse takeover, conduzido pelas multinacionais brasileiras, gerou desempenho superior? Cross-border reverse takeover tem sido a expressão usada para designar a aquisição de empresas em países desenvolvidos por empresas de países em desenvolvimento. Essas aquisições, reversas porque invertem o fluxo tradicional dos investimentos internacionais, respondem atualmente por parcela significativa desses investimentos e colocam em cheque a forma tradicional de pensar os negócios internacionais. Meu argumento é que as empresas que fizeram aquisições em países desenvolvidos passam a ter acesso aos recursos não disponíveis no país de origem, tais como novas tecnologias, técnicas de gestão mais avançadas, mercado de capitais mais desenvolvidos, recursos financeiros de baixo custo, entre outros. Por outro lado, elas já desenvolveram competências para gerir esses recursos e passam a ter vantagem competitiva sobre os competidores locais, levando ao desempenho superior. No entanto, partindo dos dados da base de dados Thomson ONE, que registra todas as fusões e aquisições anunciadas, oncluídas ou não, e empregando as metodologias de estudos de evento e de regressões multivariadas, com base em dados contábeis sobre uma amostra de empresas brasileiras listadas em bolsa de valores, esta tese demonstra que estatisticamente não é possível afirmar que essas empresas obtiveram desempenho superior.

Avaliação da concentração de retinol em fígados frescos e congelados de frangos das linhagens Cobb e Ross

The intake of adequate quantities of food, including those rich in vitamins, is necessary for a healthy life. The lack of vitamin A has been characterized as a public health problem in developing countries, however, a high intake of vitamin A can result in toxic and teratogenics effects. High concentrations of vitamin A have been observed in the livers of animals. The objective of this study was to assess the levels of retinol in chicken livers and verify the effect of frozen storage on these levels. 64 livers from two chicken strains, Cobb and Ross, were used, came from four different farms. We examined 32 livers from each strain, 8 samples from each farm. Liver sample were homogenized individually, then 4 aliquots were taken from each sample. One of aliquots was analyzed immediately after slaughter (T0), the others were analyzed after 30, 60 and 90 days of storage at -18oC (T30, T60 and T90, respectively). Retinol dosage in the liver was determined by High Performance Liquid Chromatography (HPLC). The levels of retinol varied significantly according to the strain. The mean retinol value in the fresh samples was 6678.0 ± 1337.7 and 8324.1 ± 1158.5 µg/100g in the Cobb and Ross strain, respectively. Values of 4258 ± 918.7 ± 1391.7 and 4650.5 ± 1391.7 μg/100g were found after 90 days of storage for Cobb and Ross strain, respectively. The liver freezing caused a significant reduction in their levels of retinol, causing a loss of up to 44% with respect to fresh livers. The reduction in retinol levels occurred from 30 days of storage. Even with the losses from the frozen, the ingestion of a typical portion of 100 g of liver, regardless the chicken strain analyzed, surpass all recommendations of consumption and the maximum tolerable intake of vitamin A (3000 μg/day) for adults

Avaliação de megadoses de retinol palmitato no pós-parto imediato sobre o retinol do leite de puérperas atendidas no hospital josé pedro bezerra, Natal-RN

Vitamin A deficiency (VAD) is a serious public health problem in developing countries, and as a therapeutic and prophylactic measure retinil palmitate is being supplemented. Nevertheless its efficacy has been questioned. The objective of the study was to evaluate the supplementation of two retinil palmitate megadosis on the serum retinol levels of post partum healthy mothers from Dr. José Pedro Bezerra (Hospital Santa Catarina) hospital, Natal - RN. The enrolled women (n=199) were randomly distributed into three studied groups and supplemented with retinil palmitate immediately after delivery with a single 200,000 IU dose (group S1), two 200,000 IU dose (group S2) with 24h difference between the doses, or no supplementation (group C). Among women selected, 143 remained until the end of the study. The influence of vitamin A dietary intake was evaluated during pregnancy and after 30 days of delivery. The average intake of the population was reasonable, but a high prevalence of inadequate intake was found. Retinol in colostrums and mature milk was determined by high performance liquid chromatography (HPLC). The retinol average in colostrums and mature milk in the supplemented and control groups were adequate according to the reference values. In colostrums, women from groups C, S1 and S2 presented retinol averages by milk volume of 94.8 ± 40.2 µg/dL, 92.2 ± 50.0 µg/dL and 91.8 ± 53.7 µg/dL, respectively. No difference was found between these averages (p=0.965), this was also seen when the values where expressed as µg/g of fat (p=0.905). After 30 days of delivery, retinol per milk volume differed between the control group (36.6 ± 17.5 µg/dL) and groups supplemented with 200,000 IU (51.0 ± 28.8 µg/dL) or 400,000 IU (55.2 ± 31.6 µg/dL) of retinil palmitate (p<0,05). Nevertheless, when S1 and S2 groups where compared, no significant difference was found (p=0.97). Considering retinol/g of fat, the means were 12.7 ± 6.7 µg/g, 15.6 ± 8.3 µg/g and 17.2 ± 8.9 µg/g for groups C, S1 and S2, respectively, with significant difference between groups S2 and C (p=0,01). Subclinical VAD prevalence showed a serious public health problem in the study population (32% in colostrums and 31.5% in mature milk). When analyzing the groups separately, the group which received two doses (200,000 IU + 200,000 IU) presented the lowest VAD prevalence (20.7%). Retinil palmitate supplementations of 200,000 IU and 400,000 IU (divided in two doses) in the immediate post partum showed no significant difference. Nevertheless, the 400,000 IU (divided in two doses) supplementation showed a reduction in VAD

Estado nutricional e efeito da vitamina A na resposta imune frente à infecção por Leishmania Infantum

Nutritional status is an important determinant to the response against Leishmania infection, although few studies have characterized the molecular basis for the association found between malnutrition and the disease. Vitamin A supplementation has long been used in developing countries to prevent mortality by diarrheal and respiratory diseases, but there are no studies on the role of vitamin A in Leishmania infection, although we and others have found vitamin A deficiency in visceral Leishmaniasis (VL). Regulatory T cells are induced in vitro by vitamin A metabolites and are considered important cells implicated T CD4+ cell suppression in human VL. This work aimed to examine the correlation of nutritional status and the effect of vitamin A in the response against Leishmania infantum infection. A total of 179 children were studied: 31 had active VL, 33 VL history, 44 were DTH+ and 71 were DTH- and had negative antibody to Leishmania (DTH-/Ac-). Peripheral blood monuclear cells were isolated in a subgroup of 10 active VL and 16 DTH-/Ac- children and cultivated for 20h under 5 different conditions: 1) Medium, 2) Soluble promastigote L. infantum antigens (SLA), 3) All-trans retinoic acid (ATRA), 4) SLA + ATRA and 5) Concanavalin A. T CD4+CD25highFoxp3+, T CD4+CD25-Foxp3- and CD14+ monocytes were stained and studied by flow cytometry for IL-10, TGF-β and IL-17 production. Nutritional status was compromised in VL children, which presented lower BMI/Age and retinol concentrations when compared to healthy controls. We found a negative correlation between nutritional status (measured by BMI/Age and serum retinol) and anti-Leishmania antibodies and acute phase proteins. There was no correlation between nutritional status and parasite load. ATRA presented a dual effect in Treg cells and monocytes: In healthy children (DTH-/Ac-), it induced a regulatory response, increasing IL-10 and TGF-β production; in VL children it modulated the immune response, preventing increased IL-10 production after SLA stimulation. Furthermore, we found a positive correlation between BMI/Age and IL-17 production and negative correlation between serum retinol and IL-10 and TGF-β production in T CD4+CD25highFoxp3+ cells after SLA stimulus. Our results show a potential dual role of vitamin A in the immune system: improvement of regulatory profile during homeostasis and down modulation of IL-10 in Treg cells and monocytes during symptomatic VL. Therefore, the use of vitamin A concomitant to VL therapy might improve recovery from disease status in Leishmania infantum infection

Avaliação do retinol em parturientes com diabetes mellitus gestacional no pós parto imediato

Micronutrient deficiencies affect individuals mainly in developing countries, where vitamin A deficiency is a public health problem worldwide more worrying, especially in groups with increased physiological needs such as children and women of reproductive age. Vitamin A is supplied to the body through diet and has an important role in the visual process, cell differentiation, maintenance of epithelial tissue, reproductive and resistance to infection. The literature has demonstrated the relationship between vitamin A and diabetes, including gestational, leading to a risk to both mother and child. Gestational diabetes is any decrease in glucose tolerance of variable magnitude diagnosed each the first time during pregnancy, and may or may not persist after delivery. Insulin resistance during pregnancy is associated with placental hormones, as well as excess fat. Studies have shown that retinol transport protein produced in adipose tissue in high concentrations, this would be associated with resistance by interfering with insulin signaling. Therefore, this study aimed to evaluate the concentration of retinol in serum and colostrum from healthy and diabetic mothers in the immediate postpartum period. One hundred and nine parturient women were recruited, representing seventy-three healthy and thirty-six diabetic. Retinol was extracted and subsequently analyzed by High Performance Liquid Chromatography. Among the results highlights the mothers with gestational diabetes were older than mothers healthy, had more children and a higher prevalence of cases of cesarean section. Fetal macrosomia was present in 1.4% of healthy parturient women and in 22.2% of diabetic mothers. The maternal serum retinol showed an average of 39.7 ± 12.5 mg/dL for healthy parturients 35.12 ± 15 mg/dL for diabetic and showed no statistical difference. It was observed that in the group of diabetic had 17% vitamin A deficiency, whereas in the healthy group, only 4% of the women were deficentes. Colostrum, the concentration of retinol in healthy was 131.3 ± 56.2 mg/dL and 125.3 ± 41.9 mg/dL in diabetic did not differ statistically. This concentration of retinol found in colostrum provides approximately 656.5 mg/day for infants born to healthy mothers and 626.5 mg/day for infants of diabetic mothers, based on a daily consumption of 500 mL of breast milk and need Vitamin A 400 mg/day, thus reaching the requirement of the infant. The diabetic mothers showed significant risk factors and complications related to gestational diabetes. Although no 11 difference was found in serum retinol concentration and colostrum among women with and without gestational diabetes, the individual analysis shows that parturients women with diabetes are 4.9 times more likely to develop vitamin A deficiency than healthy parturients. However, the supply of vitamin A to the newborn was not committed in the presence of gestational diabetes

Efeito da suplementação com retinol palmitato em codornas (Coturnix coturnx japonica) nos níveis de retinol na gema dos ovos

Vitamin A deficiency is a serious public health problem in developing countries, and it causes death and blindness among children in the developing countries. The fortification of food could be an important source of vitamins to control deficiency. 60 Coturnix coturnix japonica quails were used in a randomized design with duration of seven weeks. The birds were assigned into five treatments with four repetitions. The objective was to evaluate the influence of the supplementation with different levels of retinyl palmitate (2,000 IU, 4,000 IU, 8,000IU and 16,000 IU) in quails under the levels of retinyl in egg yolks. The method used to dose retinyl in yolks of quail eggs was High Performance Liquid Chromatography and the enzymatic method to quantify the cholesterol concentration. The weight and production of eggs was significantly modified by the supplementation with retinyl in the birds. The results showed a gradual increase in the incorporation of retinyl in the egg yolk as a response to the supplementation, reaching values 384% higher than the control values. By the end of the supplementations a significant reduction in the concentrations of retinyl in the eggs yolk was observed. The most lasting supplementations were with 8,000 IU and 16,000 IU which lasted for three weeks. The cholesterol content in eggs was not significantly modified. The consumption of one egg enriched with 16000UI of retinol palmitate in the present study, by day, would probably reach 10 and 7,3% of the daily recommendations of this micronutrient for children of 1 to 3 years of age, and for 4 to 8 years, respectively. The nutritional value of eggs, related to the vitamin A, can be improved by supplementation of quails

Prevalência da infecção por papilomavírus humano, herpes simplex tipo 1 e 2 e Chlamydia trachomatis em um segmento da população feminina da grande Natal/RN

Sexually transmitted diseases (STDs) are among the largest public health problems, especially in developing countries. The acquisition of these infections during early sexual activity is common and many infections have a benign course. However, in some pathogens remain in the state of latency can be reactivated and cause productive infection that may progress to severe forms. In addition, some of them are transmitted vertically resulting in congenital infection, causing immediate damage or long-term child. The classic risk factors for sexually transmitted agents are: early onset of sexual and reproductive health, multiple sexual partners throughout life, use of oral contraceptives and co-infections with different pathogens. We present the results of a cross-sectional study aimed to estimate the prevalence of genital infection by human papillomavirus (HPV), Herpes simplex virus (HSV) and Chlamydia trachomatis (CT) in a segment of the female population of the metropolitan area Christmas, among those who enrolled voluntarily sought, Basic Health Units for the examination of cancer screening cervix in the period 2008 to 2010. All participants, a total of 261 women answered a standard questionnaire by which identified the socio-demographic characteristics, classical risk factors for STDs, reproductive and sexual activity and smoking. Of each patient were obtained two samples, one for the completion of the Pap test for detection of cellular changes and the other processed for DNA extraction and analyzed by PCR (polymerase chain reaction) to detect the three pathogens studied. The population of the study was composed of sexually active women aged between 13 and 79 years, mean 38.7 years, most of them being married, low education levels and low incomes. The majority (87%) had normal results on cytology and only 2.7% had low-grade cytological abnormalities. Prevalence rates were 37.9% for HPV, 4.6% for CT and 26% for HSV. HPV prevalence was higher in women under 25, unmarried and in those who had multiple sexual partners. Women with simultaneous infection by HSV-1 and 2 had higher prevalence of HPV infection. The prevalence of HSV infection showed no association whatsoever with the risk factors analyzed and HSV-1 was the predominant type among the cases of genital HSV infection. The overall prevalence of C. Trachomatis was relatively low, thus providing greater value in younger women aged less than or equal to 20 years

Prevalência da infecção por Chlamydia Trachomatis em mulheres atendidas no Programa de rastreamento do câncer de colo do útero

Genital infection with Chlamydia trachomatis is now recognized as one of the most prevalent sexually transmitted infections (STDs). Despite major advances in laboratory diagnosis techniques, primarily the character of asymptomatic chlamydial infection in both men and in women constitutes the basis for the formation of reservoirs that perpetuate transmission and acquisition of this and other STDs. The asymptomatic in women favors the rise of infection to the upper genital tract, causing injuries that can result in infertility. An examination of population screening for early detection and treatment of asymptomatic infections is the key step in combating this major public health problem. The present study aimed to evaluate the prevalence of infection by C. trachomatis in sexually active women attended the screening program for cervical cancer of the uterus in health facilities in municipalities in different regions of the State of Rio Grande do Norte, and identify factors that may contribute to the spread of this pathogen and its relationship with the lesions of the uterine cervix. It is a cross-sectional study aimed at detecting the presence of genital tract infection by C. trachomatis either in isolated form or in association with human papilloma virus (HPV) infection in asymptomatic women. Were included in this study, a total sample of 1,134 women aged 13-76, mean 34.4 years, from March 2008 to September 2012. Specimens containing exfoliated cells of the epithelium of the uterine cervix were analyzed by examining Pap cytology for the detection of possible injuries, and the polymerase chain reaction (PCR) for detection of plasmid DNA from C. trachomatis and HPV. Infection with C. trachomatis was detected with overall prevalence rate of 8.1% in the isolated form and 2.8% in co-infection with HPV. The infection was detected in 7.4% of women with normal cytology 11.5% of those with atypical cells of undetermined significance (ASC-US) and 16.7% of those with low-grade squamous intraepithelial lesion (LSIL). We observed an association between C. trachomatis and incidence of low-grade squamous intraepithelial lesion (LSIL). The genital tract infection by C. trachomatis alone was associated with education level, ethnicity and parity, revealing that women with higher education, those of non-white ethnicity and those who had three or more pregnancies were more likely to acquire infection. Levels very close to statistical significance were observed for chronological age, age at first sexual intercourse and first pregnancy. There was no association with marital status, number of sexual partners. Co-infection with C. trachomatis and HPV was detected in 2.3% of women with normal cytology, who had 5.1% in ASC-US and 10.4% in those with LSIL. No association was found between infection C. trachomatis and increased risk of HPV infection, but women with simultaneous infection by both pathogens showed greater risk for LSIL. Co-infection was more prevalent among single women, who had in the first sexual intercourse under 18 years and those who had two or more sexual partners over a lifetime

IgA sérica, secretora, IgE total e estado nutricional em crianças com infecções por enteroparasitas

Infections for intestinal parasites are one of the main morbidade causes in humans and, its relationships with socioeconomic levels and hygiene conditions in countries in development are already very established. Many works, even so, they are being accomplished to elucidate the complex interactions among nutrition, these infections and answer imunológica, because it is seen that malnutrition commits the immunity increasing the susceptibilidade for infectious diseases and these for its time can harm the state human nutricional. It is known that sponge helmínticos they stimulate synthesis of IgE so much policlonal as specific for the same ones and that IgA secretora, main imunoglobulina of defense of the mucous ones, can act against protozoa as the Giardia lamblia and against helmintos as Trichuris tichiura and Strongyloides stercorales. Some studies show that the malnutrition energy protéica influences in the production of these answers, but some authors show results divergentes. In this work it was evaluated the levels of total IgE, IgA sérica and secretora, contagem of sanguine eosinófilos, levels of proteins séricas and state nutricional, in 103 children of low socioeconomic level, to discover a correlation between those and infection for enteroparasitas. They participated in the study children of both sexes, with age of 3 to 6 years, visitors of the same creche and residents in a neighborhood with precarious hygiene conditions and basic saneamento, in the city of Christmas. The obtained results showed that the faulty environmental and socioeconomic conditions favored to a high infection frequency for enteroparasitas, mainly Trichuris trichiura and Ascaris lumbricoides between the helmintos and Endolimax sleep and Giárdia lamblia among the protozoa. Light malnutrition without deficit protéico was observed in 30% of the children, which didn't also present significant deficiencies of IgA sérica and secretora. The sponged children
