title: Unpresentness and anachronism in the contemporary photography

description: Abstract This paper discusses the individuation conditions of the so-called contemporary photography by examining the notion of anachronism in different artworks and authors as Jeff Wall and Cindy Sherman. The construction of visual discursivity in art as a matter of communication comes from the idea that it would exist, in nowadays particular images, an unpresentness perceivable through persistent pictorial traces and issues of other times, particularly in art history. The relevance of thinking on the experience of photography in art points to its contributions for discussing communicative aspects of photography, mostly the representation that order the visible, as well as their operations that mediate our relationship with the world through the image.

title: Learning, Portfolio Complexity and Informational Asymmetry in Forecasts of Sell-Side Analysts

description: ABSTRACT The aim of this study was to analyze the association of learning and complexity in the target price forecasts and sell-side analysts' recommendations on the BM&FBovespa. The sample comprised forecasts of 195 stocks, 75 brokers and 569 analysts between 2005 and 2013, analyzed by linear models with panel data. Our results suggest that the experience with the stock, with the sector and complexity of the portfolio confirmed the learn by doing, but the overall experience showed contradictions due to information asymmetry. Despite anchoring in their peers, analysts achieved significant returns, but showed forecasts with low accuracy. Therfore, we concluded that more experienced analysts may intentionally contradict themselves in an attempt to bias the market. Finally, we suggest the development of less biased analyst rankings in order to increase the competitiveness and quality in the results of the analyzes.

title: LESIONS ASSOCIATED WITH SUBCLINICAL LAMINITIS AND DIGITAL RADIOGRAPHIC EXAM IN HOLSTEIN COWS IN THE TRANSITIONAL PERIOD

description: Abstract Subclinical laminitis has been responsible for economic losses in dairy industry; thus, its diagnostic is very important to prevent negative responses to milk production industry. The aim of this study was to identify lesions associated with subclinical laminitis during the transition period with presence or absence of radiographic signs linked to this disease in Holstein cows. The cows were evaluated during the transition period and categorized into two groups (with and without laminitis) according to the lesions associated with this subclinical disease. The radiological dynamic was performed in two target points during the transition period (prepartum and postpartum), with the objective of determining capsular position possible alterations and third phalanx bone degeneration (F3). There was no effect of the presence of lesions associated with subclinical laminitis regarding the position of the third phalanx to the hoof wall (p&gt;0.05). Significant radiographic angular differences (p&lt;0.05) between F3 and the hoof wall were observed between the lateral and medial nails of the same digit, but not within groups (p&gt;0.05). Overall, this study did not show radiographic signs of phalangeal misalignment in the hoof of dairy cows with lesions associated with subclinical laminitis during the transition period.

title: Adoption of Technological Products and Services for Different Consumer Profiles: An analysis using the Technology Adoption Propensity Scale

description: Abstract Purpose: To evaluate how different consumer profiles react to the adoption of new technologies through the replication and validation of the TAP scale in Brazil. Design/methodology/approach: We designed a descriptive study of a quantitative nature applied through a survey. Exploratory and confirmatory factorial analysis procedures were performed in order to validate the scale. We used t tests to check for statistical differences between consumer profiles. Findings: The TAP scale proved to be a valid and reliable instrument to measure technology adoption propensity among Brazilian consumers. In this group, those in a higher domain of computational innovation showed greater proficiency in the technology adoption process. In a comparison of the data from our study with those of the original one in the USA, Brazilians presented a higher propensity for technology adoption. Originality/value: The study provided advancements in three ways: 1) validating the TAP scale for Brazilian usage; 2) bringing insights to research on innovation in specific domains; 3) contributing to the studies about potential differences between developed and emergent countries related to new technology adoption and late acceptance of innovation.

title: Radioiodine-induced oxidative stress in patients with differentiated thyroid carcinoma and effect of supplementation with vitamins C and E and selenium (antioxidants)

description: ABSTRACT Objective The objective of this study, in addition to confirming that therapy with 131I causes oxidative stress, was to evaluate the effect of supplementation with vitamins C and E and selenium on this phenomenon by measuring plasma 8-epi-PGF2a, a marker of lipid peroxidation. Subjects and methods Forty patients with thyroid cancer submitted to thyroidectomy, who received 3.7 GBq 131I after levothyroxine withdrawal, were selected; 20 patients did not receive (control group) and 20 patients received (intervention group) daily supplementation consisting of 2000 mg vitamin C, 1000 mg vitamin E and 400 µg selenium for 21 days before 131I. Plasma 8-epi-PGF2a was measured immediately before and 2 and 7 days after 131I. Results A significant increase in plasma 8-epi-PGF2a after 131I was observed in the two groups. The concentrations of 8-epi-PGF2α were significantly higher in the control group before and 2 and 7 days after 131I. The percentage of patients with elevated 8-epi-PGF2α was also significantly higher in the control group before and after 131I. Furthermore, the increase (percent) in 8-epi-PGF2α was significantly greater in the control group (average of 112.3% versus 56.3%). Only two patients (10%) reported side effects during supplementation. Conclusions Ablation with 131I causes oxidative stress which can be minimized by the use of antioxidants.

title: Physical Activity and Incidence of Atrial Fibrillation - Systematic Review and Meta-Analysis

description: Abstract Background: The relationship between exercise and atrial fibrillation (AF) is controversial. Objectives: To analyze the effects of physical activity on the incidence of atrial fibrillation using systematic review and meta-analysis. Methods: Systematic review and meta-analysis of studies that relate physical exercise and atrial fibrillation. The following databases were searched: PubMed, BVS Saúde and Cochrane. The following descriptors were used: "atrial fibrillation", "exercise", "physical activity" and "exercise therapy". All prospective, retrospective, cross-sectional and cohort studies were investigated. All statistical analyzes were provided using Review Manager 5.3 to provide the mean difference (MD) and relative risk (RR) ratio with 95% confidence intervals (95% CI). The statistical method of heterogeneity index was used to assess heterogeneity. Level of significance was 5%. Results: Combined analysis of 11 studies totaling 276,323 participants aged between 12 and 90 years did not suggest a significant increase in AF in individuals submitted to physical exercise (RR = 0.914, 95% CI = 0.833-1.003, heterogeneity: p &lt; 0.001). Conclusions: Physical exercise, lato sensu, without stratification by intensity, sex or age does not seem to be associated with an increase of atrial fibrillation.

title: Food or commodity? Indicators of food self-sufficiency in Agribusiness territories, Mato Grosso, Brazil

description: ABSTRACT The land use for the production of agricultural commodities in municipalities of the agribusiness in Mato Grosso state has been occupying space for food production. The objective of this study was to present and discuss a composite indicator of self-sufficiency assessment in the production of food in interface with the implications of the agribusiness productive model, in the perspective of the food sovereignty of the territories, based on a case study carried out in the counties Campos de Júlio, Sapezal and Campo Novo dos Parecis. Socioeconomic data were collected based on the IBGE/2010 Demographic Census, Profile of Brazilian States and Municipalities/IBGE (Brazilian Institute of Geography and Statistics), 2014, and the Agricultural Census of 2006. For production survey, data available in the IBGE System of Automatic Recovery (Sidra) were used for the year of 2016. Informations were obtained on the cultivated area of cotton, rice, banana, coffee, sugarcane, citrus, beans, sunflower, corn, soybean, tomato. Interviews were conducted with rural workers and horticulturists. Based on the data, composite indicators were developed for proposing a food self-sufficiency scale in the territories studied. The results point to iniquities in the occupation of the territories, dependence on food from other regions and increased use of pesticides as a consequence of the adopted production model, affecting local food production.

title: MONITORING POSITIVITY FOR Schistosoma mansoni IN RODENTS Holochilus sp. NATURALLY INFECTED

description: AbstractThe occurrence of non-human mammals such as schistosomiasis reservoir has always been an aggravating factor to be studied. Family cricetidae rodents like Nectomys sp, seem to have an important role in the potentiation of the spread of it. However, for Holochilus sp. (Rodentia: Cricetidae), found in Maranhão, studies with this function seem scarce. Thereby, we aimmed to analyze the infection rate of these animals for S. mansoni in São Bento - MA, endemic area for the parasite. These rodents were monitored during 12 months, by the Tomahawk traps for caught and triplicates of stool tests blades, made by Kato-Katz kit, for parasitogical exam. A total of 101 rodents were captured, of which 28.7% were naturally infected by S. mansoni (17.3% females and 82.7% males). This analysis showed that an average of 2.4 rodents was infected for one year, being possible to find positive animals in almost all the collects. Therefore, the rodent Holochilus sp. is a potential candidate in ensuring the maintenance of the schistosomiasis cycle in the region under study.

title: Correlations of rock mass classifications applied to ferruginous caves

description: Abstract For the Brazilian iron ore mines, the presence of caves presents a challenge, since most of them are located within the ore deposit. The National Environment Commission (CONAMA 347 Resolution/2004) establishes that the speleological heritage, as well as its area of influence, cannot sustain irreversible environmental impacts. The physical integrity of caves adjacent to mining operations is an issue of pivotal importance to be scrutinised in studies towards the delimitation of the cave’s protection radius. This article presents the study of various models of correlation between the RMR and Q systems used for the stability assessment of natural iron ore caves. In order to study a correlation between the RMR and Q systems, the most popular rock mass classifications, and their application as a validation tool, a selection of measurements of Q and RMR, organized in a database from seven natural caves of ferruginous lithology, are submitted to a study and statistical analysis. An empirical equation was obtained from the data, using a simple linear regression. The result of the regression was compared with selected correlation equations and the best fit for the data was chosen. The best fit was the Rutledge & Pearson correlation equation, which presented the best combination of R² and S, after the equation created on basis of the real values for RMR, though the other equations have results similar to it. As the results were quite similar, the recommendation still is that correlations should be used with caution, and associated to other methods and field analysis.

title: Relative Motion Guidance, Navigation and Control for Autonomous Orbital Rendezvous

description: ABSTRACT: In this paper, the dynamics of the relative motion problem in a perturbed orbital environment are exploited based on Gauss' variational equations. The relative coordinate frame (Hill frame) is studied to describe the relative motion. A linear high fidelity model is developed to describe the relative motion. This model takes into account primary gravitational and atmospheric drag perturbations. In addition, this model is used in the design of a control, guidance, and navigation system of a chaser vehicle to approach towards and to depart from a target vehicle in proximity operations. Relative navigation uses an extended Kalman filter based on this relative model to estimate the relative position and velocity of the chaser vehicle with respect to the target vehicle and the chaser attitude and gyros biases. This filter uses the range and angle measurements of the target relative to the chaser from a simulated Light Detection and Ranging (LIDAR) system, along with the star tracker and gyro measurements of the chaser. The corresponding measurement models, process noise matrix and other filter parameters are provided. Numerical simulations are performed to assess the precision of this model with respect to the full nonlinear model.The analyses include the navigations errors, trajectory dispersions, and attitude dispersions.

title: Cartography of internal migration in Mozambique between 1997 and 2007

description: Abstract The paper “Cartography of internal migration in Mozambique between 1997and 2007” results from an exploratory analysis of information pertaining to internal migration based on demographic census data between 1997 and 2007 respectively; the second and third censuses of Mozambique following national independence in 1975. The analysis is made according to the lifelong or accumulated migration observed among Mozambique’s eleven provinces in the censuses of 1997 and 2007. Also registered is migration in the five-year period before the demographic census of 2007 (that is, the period between 2002 and 2007). As a result of this analysis, the paper presents migration flows among provinces and also the volume of accumulated migration by sex and province, in 1997 and 2007. These data are presented as the volumes of inter-provincial migration of five-year 2002-2007. Furthermore, the analysis permits the grouping of the provinces in three categories according migratory trends: the first is composed of immigration provinces (Niassa, Manica and Maputo); the second of emigration provinces (Zambezia, Tete, Inhambane and Gaza); and the third, of provinces which from one period to another, changed the migration trend (Sofala, Cabo Delgado, Nampula and the City of Maputo). Lastly, the results indicate that in southern provinces of Mozambique, the proportion of women in total volume of migrants surpasses the proportion of men.
