Under-reporting of energy intake is more prevalent in a healthy dietary pattern cluster

The aim of the present study was to determine whether under-reporting rates vary between dietary pattern Clusters. Subjects were sixty-five Brazilian women. During 3 weeks, anthropometric data were collected. total energy expenditure (TEE) was determined by the doubly labelled water method and diet Was Measured. Energy intake (El) and the daily frequency of consumption per 1000 kJ of twenty-two food groups were obtained from a FFQ. These frequencies were entered into a Cluster analysis procedure in order to obtain dietary patterns. Under-reporters were defined Lis those who did not lose more than 1 kg of body weight during the study and presented EI:TEE less than 0.82. Three dietary pattern clusters were identified and named according to their most recurrent food groups: sweet foods (SW). starchy foods (ST) and health), (H). Subjects from the healthy cluster had the lowest mean EI:TEE (SW = 0.86, ST = 0.71 and H = 0.58: P = 0.003) and EI - TEE (SW = -0.49 MJ, ST = - 3.20 MJ and H = -5.09 MJ; P = 0.008). The proportion of Under-reporters was 45.2 (95 % CI 35.5, 55.0) % in the SW Cluster: 58.3 (95 % CI 48.6, 68.0) % in the ST Cluster and 70.0 (95 % CI 61.0, 79) % in the H cluster (P=0.34). Thus, in Brazilian women, Under-reporting of El is not uniformly distributed among, dietary pattern clusters and tends to be more severe among subjects from the healthy cluster. This cluster is more consistent with both dietary guidelines and with what lay individuals usually consider `healthy eating`.

Formulation of a tropical town energy budget (t-TEB) scheme

This work describes the tropical town energy budget (t-TEB) scheme addressed to simulate the diurnal occurrence of the urban heat island (UHI) as observed in the Metropolitan Area of Rio de Janeiro (MARJ; -22A degrees S; -44A degrees W) in Brazil. Reasoning about the tropical urban climate have guided the scheme implementation, starting from the original equations from Masson (Bound-Lay Meteorol 94:357-397, 2000). The modifications include (a) local scaling approaches for obtaining flux-gradient relationships in the roughness sub-layer, (b) the Monin-Obukhov similarity framework in the inertial sub-layer, (c) increasing aerodynamic conductance toward more unstable conditions, and (d) a modified urban subsurface drainage system to transfer the intercepted rainwater by roofs to the roads. Simulations along 2007 for the MARJ are obtained and compared with the climatology. The t-TEB simulation is consistent with the observations, suggesting that the timing and dynamics of the UHI in tropical cities could vary significantly from the familiar patterns observed in mid-latitude cities-with the peak heat island intensity occurring in the morning than at night. The simulations are suggesting that the thermal phase shift of this tropical diurnal UHI is a response of the surface energy budget to the large amount of solar radiation, intense evapotranspiration, and thermal response of the vegetated surfaces over a very humid soil layer.

Alternative mating tactics in dimorphic males of the harvestman Longiperna concolor (Arachnida: Opiliones)

Intense male-male competition for females may drive the evolution of male morphological dimorphism, which is frequently associated with alternative mating tactics. Using modern techniques for the detection of discontinuous allometries, we describe male dimorphism in the Neotropical harvestman Longiperna concolor, the males of which use their elongated, sexually dimorphic legs IV in fights for the possession of territories where females lay eggs. We also tested three predictions related to the existence of alternative mating tactics: (1) if individuals with relatively longer legs IV (majors) are more likely to monopolize access to reproductive resources, they are expected to remain close to stable groups of females more than individuals with relatively shorter legs IV (minors) do; (2) if minors achieve fertilization by moving between territories, they are expected to be less faithful to specific sites; and (3) majors should be observed in aggressive interactions more often. We individually marked all the individuals from a population of Longiperna during the reproductive season and recorded the location of each sighting for males and females as well as the identity of males involved in fights. Majors were more likely to have harems, and large majors were even more likely to do so. Majors were more philopatric and all males involved in fights belonged to this morph. These results strongly suggest that the mating tactic of the majors is based on resource defense whereas that of the minors probably relies on sneaking into the territories of the majors and furtively copulating with females.

Mating behavior of Sickius longibulbi (Araneae, Theraphosidae, Ischnocolinae), a spider that lacks spermathecae

We describe the mating behavior in the spermatheca-lacking theraphosid species Sickius longibulbi Soares & Camargo 1948. The behavior in captivity of nine pairs of S. longibulbi was videotaped and analyzed. The matting of this species presented an uncommon theraphosid pattern. There is little in the way of overt courtship by the male, the primary behavior seen being the male`s use of legs I and II to touch the female`s first pairs of legs and her chelicerae. Sometimes the male clasped one of the female`s first pairs of legs, bringing her close to him. While the female raised her body, the male clasped her fangs and held her tightly with his legs III wrapped around her prosoma. The male seemed to try to knock the female down, pushing her entire body until she lay on her dorsum. In this phase we observed the male biting the female on the sternum or on the leg joints. When the female fell, the male attempted to position himself at an angle of 90 degrees from the female. These movements appear to demand a lot of energy, particularly because the female is not passive during the mating. Our findings suggest that copulating in this position is, for the male, more successful than adopting other positions because it allows his extremely long palpal bulbs to deposit more sperm in the female oviduct where - since she lacks spermathecae - she retains the sperm. We suggest that the further he reaches into the oviduct, the greater the chance that he will fertilize the female`s eggs.

Advanced functionality for radio analysis in the Offline software framework of the Pierre Auger Observatory

The advent of the Auger Engineering Radio Array (AERA) necessitates the development of a powerful framework for the analysis of radio measurements of cosmic ray air showers. As AERA performs ""radio-hybrid"" measurements of air shower radio emission in coincidence with the surface particle detectors and fluorescence telescopes of the Pierre Auger Observatory, the radio analysis functionality had to be incorporated in the existing hybrid analysis solutions for fluorescence and surface detector data. This goal has been achieved in a natural way by extending the existing Auger Offline software framework with radio functionality. In this article, we lay out the design, highlights and features of the radio extension implemented in the Auger Offline framework. Its functionality has achieved a high degree of sophistication and offers advanced features such as vectorial reconstruction of the electric field, advanced signal processing algorithms, a transparent and efficient handling of FFTs, a very detailed simulation of detector effects, and the read-in of multiple data formats including data from various radio simulation codes. The source code of this radio functionality can be made available to interested parties on request. (C) 2011 Elsevier B.V. All rights reserved.

Effect of urea and glycine fuels on the combustion reaction synthesis of Mn-Zn ferrites: Evaluation of morphology and magnetic properties

The goal of this study is to evaluate the influence of the urea and glycine fuels on the synthesis of Mn-Zn ferrite by combustion reaction The morphology and magnetic properties of the resulting powders were investigated. The powders were characterized by X-ray diffraction (XRD), nitrogen adsorption (BET), scanning and transmission electron microscopy (SEM and TEM), and magnetic measurement of M x H curves. The X-lay diffraction patterns indicated that the samples containing urea resulted in the formation of crystalline powders and the presence of hematite as a secondary phase The samples containing glycine presented only the formation of crystalline and monophases (Mn,Zn)Fe(2)O(4). The average crystallite size was 18 and 35 nm and saturation magnetization was 3.6 and 75 emu/g, respectively, for the samples containing urea and glycine. The samples synthesized with glycine fuel showed better magnetic properties for application as soft magnetic devices. (C) 2009 Elsevier B.V All rights reserved

Att prata ihop sig i rätten

Negotiating experience in the court How do judges assess witness credibility, and how do they proceed to reach sustainable conclusions in a criminal court? This article is based on discussions in four focus groups with lay judges in Swedish district courts. In criminal court trials, a version of an event is generally reinforced if it is confirmed by witnesses. However, if their narratives are too similar, none of them is found trustworthy. The focus group participants agreed that if witnesses were suspected of having discussed their individual experiences of an event and accommodated them into a common story, their testimonies were not considered credible. While testimonies should ideally be untainted by other people’s impressions and opinions, other rules govern the truth of the court. The lay judges appreciated their deliberations, including negotiations on impressions and memories of the trial, and they sometimes adjusted their perceptions in the light of information provided by other members of the court. However, if the lay judges are viewed as witnesses of what takes place in the trial, this gives rise to a paradox: While witness negotiations on experiences are regarded as a means to construct a false or biased story, the same kind of interaction between the judges is considered necessary to establish a consensual truth of what actually happened.

Politian: a critical analysis

Why even look at Politian, an unfinished failure? While it is true that Politian was a failure for its time and surely one of Poe's least successful attempts, it may improve on a stage with a more modern perspective. If not solely for examination of Poe's artistic effort, Politian also warrants a closer read due to its historical relevance by way of Beauchamp and Sharp. Poe, a most fastidious editor of his work, was ultimately required because of financial constraints to lay aside Politian in its unfinished state. As a result, the unedited Politian may provide insight into the writing process of Poe that other polished pieces cannot, and that, if nothing else, warrants a more precise study of his play.

Investigação de fatores que afetam o desempenho e apropriação de espaços abertos públicos : o caso de Campo Grande - MS

Esta pesquisa investigou os fatores que afetam a apropriação de espaços abertos públicos - ruas e espaços públicos de lazer -, adotando como estudo de caso a cidade de Campo Grande – MS. Procurou entender as causas de diferentes níveis de apropriação de espaços públicos abertos, através de uma abordagem perceptiva que utilizou a satisfação do usuário e o comportamento ambiental como indicadores de desempenho dos espaços estudados. Este é avaliado a partir das percepções dos moradores e usuários sobre as áreas selecionadas, e da verificação do perfil comportamental dos espaços. O objetivo principal deste trabalho é a investigação de quais aspectos afetam mais fortemente os tipos e intensidade de uso diferenciados dos espaços abertos públicos, se fatores composicionais ou fatores contextuais. O levantamento de dados foi realizado através da aplicação de múltiplos métodos: levantamentos de arquivos, levantamentos físicos, observações comportamentais, aplicação de questionários e entrevistas. A análise destes dados possibilitou uma maior precisão e validade da investigação A análise das relações entre características individuais dos usuários e nível de apropriação dos espaços públicos e entre atributos ambientais e diferentes níveis de apropriação dos espaços públicos, indicam que os aspectos composicionais de ordem socioeconômica afetam fortemente o tipo e intensidade de uso das ruas residenciais. Em relação aos espaços públicos de lazer, os resultados evidenciam a forte influência de aspectos de ordem física no tipo e intensidade de uso. As conclusões indicam que, se for desejável uma dinamização das ruas para atividades sociais, é possível alcançar o objetivo, em certa medida (que depende especialmente de valores relacionados com o nível socio-econômico da população atingida), criando condições físicas que favoreçam o encontro e a permanência. Quanto aos espaços públicos de lazer as conclusões indicam que investimentos no planejamento físico destes, embasados em conhecimento real das necessidades da população alvo, darão retorno consistente em maior uso.

Time-series properties and empirical evidence of growth and infraestructure: revised version

After more than forty years studying growth, there are two classes of growth models that have emerged: exogenous and endogenous growth models. Since both try to mimic the same set of long-run stylized facts, they are observationally equivalent in some respects. Our goals in this paper are twofold First, we discuss the time-series properties of growth models in a way that is useful for assessing their fit to the data. Second, we investigate whether these two models successfully conforms to U.S. post-war data. We use cointegration techniques to estimate and test long-run capital elasticities, exogeneity tests to investigate the exogeneity status of TFP, and Granger-causality tests to examine temporal precedence of TFP with respect to infrastructure expenditures. The empirical evidence is robust in confirming the existence of a unity long-run capital elasticity. The analysis of TFP reveals that it is not weakly exogenous in the exogenous growth model Granger-causality test results show unequivocally that there is no evidence that TFP for both models precede infrastructure expenditures not being preceded by it. On the contrary, we find some evidence that infras- tructure investment precedes TFP. Our estimated impact of infrastructure on TFP lay rougbly in the interval (0.19, 0.27).

Administração judiciária e os juizados especiais cíveis: o caso do Rio Grande do Sul

Os Juizados Especiais foram criados para proporcionar acesso à justiça, de forma simples e rápida, sem custos, objetivando resolver conflitos de menor complexidade, de modo informal e preferencialmente através da conciliação. Decorridas mais de duas décadas desde a sua implantação, no Rio Grande do Sul, o sistema não vêm tendo a devida atenção, quer de parte dos operadores, quer de parte do próprio Judiciário. O risco de contaminação das práticas do sistema tradicional de justiça, burocrático e formalista e, por isso mesmo, moroso, exige medidas de administração judiciária que evitem o desvirtuamento dos princípios com base nos quais os Juizados Especiais foram concebidos. A correta atuação dos Juízes Presidentes dos Juizados Especiais, a orientação aos servidores que nele atuam, a prévia preparação dos juízes leigos e conciliadores para o exercício das relevantes funções que lhes são atribuídas, o comprometimento dos integrantes das Turmas Recursais com a unidade do sistema e, fundamentalmente, gestão deste pelo órgão estadual responsável pela coordenação e supervisão dos Juizados Especiais, são medidas que, juntamente com os necessários investimentos em informatização, incentivo à inovação e ao uso das novas tecnologias, padronização de procedimentos, aperfeiçoamento dos bancos de dados e sistema estatístico, podem promover melhorias significativas no seu desempenho.

Enxugamentos de pessoal em empresas no Brasil: pesquisa de campo comparativa sobre moderadores organizacionais dos efeitos de demissões coletivas em empresa e indivíduo

O estudo aqui exposto envolve uma pesquisa empírica qualitativa, de natureza exploratória, cuja meta é ilustrar empiricamente algumas conclusões teóricas da tese de doutoramento do autor, em especial aquelas que sugerem que certos fatores (moderadores - variáveis independentes) sob controle da organização podem mediar os efeitos (variáveis dependentes) de enxugamentos na empresa, nos remanescentes e nos demitidos. O método do estudo foi baseado na análise comparada em profundidade de um painel de 4 empresas no Brasil que conduziram processos enxugamentos de pessoal nos últimos anos, e inclui o levantamento e a comparação estruturada de dados junto à direção de cada empresa, sindicatos, líderes comunitários, demitidos e remanescentes.

Gestão de transferência de inovações tecnológicas para empresas do setor produtivo: complexidade no relacionamento entre organizações de culturas diferentes

The motivation of this study is based on the expectation of understanding, at least in part, the reason why the brazilian academic production ¿ which is among the largest if compared to the developing countries, has not been translated in a useful way into concrete technology transference for the production sector. The supposition that different cultures and subcultures, in terms of values, behavior, practices among organizations and groups of selected actors involved in that process,- which is the central problem of this study, and peculiar to the technology context, has elected that relationship process the object of this research this study theoretical fundaments rely on culture and technology to analyze the subcultures which manifest themselves through the typified groups of researchers, in the public organizations, small scale employers, acting on technology based companies in the private sector (ebts) and mediators. Who also act in the process the preliminary step was the case study. Several qualitative methods an procedures were used. And the investigation has advanced toward interacting interviews, at the end added by the focal group method. The conclusions reject the existence of incompatibility among the subject groups points of view, however, points out some divergent values, the presence of mutual stereotypes and also confirms the supposition that the research platform is strongly influenced by the financial factor. Although, the study reveals that the presence of common objectives which lay behind the cited divergences make possible to present a core of practical suggestions to implement the studied relationships for the benefit of the production sector as well. The peculiarities perceived while dealing with that singular context suggest futures research to clarify possible new and obscure areas in that complex relationships.

Ruptura e Legado: o colapso da cordialidade oficial entre o Brasil e a Argentina

Este trabalho busca identificar os fatores que concorrem para explicar a mudança no eixo entre a Argentina e o Brasil, no começo da década de 1980, quando as duas diplomacias convergiram em um projeto de integração inovador. O argumento apresentado defende que a aproximação entre os dois países foi o legado, inesperado, do relacionamento bilateral ao longo da gestão do Presidente Geisel (1974-1979).
