title: Germination constraints of dicarpic cypselae of Bidens pilosa L.

description: Abstract Bidens pilosa L. is a heterocarpic weed species with two cypselae types that present morpho-physiological differences, being the peripheral type smaller and slower to germinate than the central one. We aimed to verify how the germination mechanism varied between types. We focused on two mechanisms: (1) pericarp constraints (physical and chemical) and (2) hormonal stimulation (Abcisic acid [ABA] and Gibberellin [GA]). Both cypselae types are physically constrained by the pericarp, for when it is excised both seed types increase their germination, but behavioral differences still remain. The pericarp of the peripheral type also has chemical inhibitors that effectively inhibited germination of the intact central cypsela. To test the hormonal effects, we focused on the ABA:GA control. Both cypselae responded to an exogenous ABA concentration gradient, however there is no variation between types on the sensitivity to it. Also, both cypselae types were indifferent to Fluridone (ABA inhibitor), which indicates that the dormancy is not maintained by de novo ABA synthesis. Cypselae types had different sensitivity to an exogenous GA3 gradient, the central type being more sensitive to the treatment than the peripheral one. But when the endogenous GA synthesis was blocked by Paclobutrazol, both types responded equally to same GA3 concentrations. This indicates that endogenous GA synthesis may be related to differences observed on germination of cypselae types. To conclude, seed types differ on their growth potential to overcome the pericarp resistance: while the inhibitor in the peripheral pericarp reduces growth potential, GA increases it.

title: THE DESIGNATED VICTIM: REPRESENTATIONS OF HUMAN TRAFFICKING IN BRAZIL

description: This article analyzes the images of human trafficking presented by the principal anti-trafficking campaigns created by the Brazilian state and some of its most important allies in civil society. We seek to understand how these campaigns represent victims, perpetrators and trafficking itself in their attempts to inculcate in Brazilian society a culture of “resistance to modern slavery”. Such a culture has as its most important component the anonymous denunciation of “suspicious people”. We present an ideal typography of these images, comparing them to similar images produced in the Western European and North American contexts. We then look at the changes and continuities that appear in the Brazilian images over the years, and analyze some of the specific characteristics of Brazilian campaigns. We conclude with a brief discussion of the possible side effects of campaigns that are based on these kinds of iconography.

title: Historical records of orchid bees (Apidae: Euglossini) in Belém Endemism Center: species list of 92 years sampling

description: Abstract The distribution of most species occurs in delimited regions with unique characteristics called “centers of endemism”. In Eastern Amazon is located the Belém Endemism Center (BEC), one of the most intensely deforested in Brazilian Amazon. Here, we show information about orchid bee assemblages based on historical records from entomological collections. For each species, we calculated occurrence frequency and dominance, and we classified them in 3 statuses: common, intermediate or rare species. Curves of observed and estimated richness were built, based on Jackknife estimator. We found 1,257 specimens from 56 species, constituting records from 1917 to 2009, and one species is a new record for BEC. Higher number of specimens and species was concentrated in a few locations and surveys increased from the 70’s. The results suggest a high richness of orchid bees in the BEC, although this scenario is far from what is expected for the entire area. The high occurrence of rare species may be related to their low representativeness in the collections, and the proximity between the areas had favored samplings. Even so, the species list and the conservation status presented here may be useful information in studies comparing past and current orchid bee fauna, and, allied to data on bees’ responses to land use changes occurred in BEC over the years, can fit as a basis for defining priority areas for conservation.

title: Use of the robust design methodology for identification of factors that contribute to the intensity of the “orange peel” aspect on painted bumper surfaces

description: Abstract Even with the considerable development of techniques for automotive paint in recent decades, the bumper is a car part that still has many problems related to the aspect of its painted surface. This study aimed to identify the clear coat application factors that affect on the intensity of orange peel appearance on painted bumpers surfaces and offer an optimum design of factors through the robust design methodology. In this research conducted in automated paint sector of a bumper company, the robust design helped in the identification of variability cause in a production process by applying an experiment and statistical techniques, in an agile and with little waste material way. The experiment tested various combinations of levels of the clear coat application factors (speed, flow, revolution per minute, operation voltage, atomizing air pressure) in the bumper samples. The intensity of the orange peel on coated surfaces samples was measured by a Wave Scan device that provides the wavelength reading as a function of two measures: Long Wave and Short Wave. The main results obtained by variance analysis of noise signal ratio showed that the factors that have significant effects on the value of the Short Wave response wavelength are: revolution per minute, operation voltage and the interactions flow*operation voltage and speed*operation voltage. The factors that significantly affected the response value of the Long Wave wavelength are: flow, atomizing air pressure, revolution per minute, operation voltage and the interaction speed*operation voltage. As a result of analysis of the noise signal mean, it is presented the factors optimum design: speed = 920 m / s; flow = 160 ml/min; atomizing air pressure = 180 bar; revolution per minute = 90 revolutions / minute; operation voltage = 180 kilovolts.

title: UNION LEGISLATIVE BLOC, SOCIAL SECURITY POLICY AND DECISION-MAKING PROCESS IN DILMA’S GOVERNMENT

description: This study looks into the participation of unionist parliamentarians in the decision making process for the establishment of the Fundação de Previdência Complementar do Servidor Público Federal, during the first mandate of the Dilma Rousseff government. We formulated the research problem in the following manner: in a political institutional context in which the unionist bloc is part of the government coalition, how do unionist parliamentarians position themselves in law propositions that negatively affect the interests of important parts of their social representative base? The research findings reinforce the thesis of partisan preponderance in the Brazilian decision-making process. The majority of unionist parliamentarians, including those originally from the public sector, defended and voted favorably for passing the Bill 1992/2007, which established the Funpresp. This was the case even under strong opposition from federal public servants from the Executive, Legislative, and Judicial branches.

title: Adropin and Irisin in Patients with Cardiac Cachexia

description: Abstract Background: Cardiac cachexia is an important predictive factor of the reduction in survival of patients with heart failure with reduced ejection fraction. Objectives: The aims of the present study were to evaluate adropin and irisin levels in cachectic and non-cachectic subjects and the relationships between the levels of these proteins and clinical and laboratory parameters in patients with HFrEF. Methods: The clinical records of patients who were admitted to the cardiology outpatient clinic for heart failure with reduced ejection fraction were screened. Cachectic patients were identified and assigned to the study group (n = 44, mean age, 65.4 ± 11.2 y; 61.4% men). Heart failure with reduced ejection fraction patients without weight loss were enrolled as the control group (n = 42, mean age, 61.0 ± 16.5 y; 64.3% men). The serum adropin and irisin levels of all patients were measured. A p-value &lt; 0.05 was considered significant. Results: Serum adropin and irisin levels were significantly higher in the cachexia group than in the controls (Adropin (ng/L); 286.1 (231.3-404.0) vs 213.7 (203.1-251.3); p &lt; 0.001, Irisin (µg/mL); 2.6 (2.2-4.4) vs 2.1 (1.8-2.4); p = 0.001). Serum adropin and irisin levels were positively correlated with brain natriuretic peptide (BNP) levels and New York Heart Association (NYHA) class and negatively correlated with body mass index (BMI) and serum albumin levels (all p values: &lt; 0.001). In a multivariate analysis, adropin was the only independent predictor of cachexia in the heart failure with reduced ejection fraction patients (OR: 1.021; 95% CI: 1.004−1.038; p = 0.017). Conclusions: The results suggest that adropin and irisin may be novel markers of cardiac cachexia in heart failure with reduced ejection fraction patients. Adropin and irisin are related with the severity of heart failure.

title: THE EGG AND THE CHICKEN ANALOGY: STUDY OF THE FRAMEWORK AND RECEPTION OF JOURNALISTIC COVERAGE IN THE 2014 ELECTIONS

description: Starting from a critical review of the literature on the economic vote, on the one hand, and on news media coverage in electoral periods, on the other hand, we propose a study that combines the analysis of the content of journalistic texts the perceptions of media consumers. Our analysis combines the emission and the reception of news content. We propose the hypothesis that the framework (with notions of valence and accountability of events) printed by the vehicle in its coverage is associated with the reader / voter’s perception of the economy and the performance of the federal government. First, it was conducted a quantitative analysis of the economic and federal government framework in the news published by Folha de S. Paulo, O Estado de S. Paulo, O Globo and Jornal Nacional, from August to October 2014. Next, we selected data on perceptions of the state of the economic and the Federal Government of consumers of these media during the same period. Applying multinomial logistic models,and using government satisfaction and economy valuation as dependent variables, we conclude that that being an audience of Jornal Nacional and being a reader of O Globo reduce the chances of evaluating the economy well, but do not directly impact the evaluation of the Federal Government, while being a Folha de S. Paulo reader does not alter the chances of evaluating the economy and the Federal Government.

title: EFFICACY AND SAFETY OF LUMBAR ARTHROPLASTY IN DEGENERATIVE DISC DISEASE

description: ABSTRACT Objective: The objective of this longitudinal retrospective study is to assess the efficacy and safety of total lumbar disc replacement in patients with degenerative discopathy (L3-L4, L4-L5, L5-S1). Methods: One hundred and forty-three patients with low back pain, with or without radiculopathy, who met the radiographic criteria underwent anterior arthroplasty between 2000 and 2016. The Oswestry disability index (ODI), the visual analog scale (VAS), patient satisfaction, success criteria, disc height, and range of motion of the operated segment were evaluated preoperatively and at 3, 6, 12, and 24 months following surgery. Results: There were 50 men and 93 women, with an average age of 39.5 years, 13 patients (9%) with previous discectomy. The arthroplasty was performed at level L5-S1 in 97 patients (67.8%), at level L4-L5 in 45 patients (31.5%), and at level L3-L4 in 1 patient. Between the preoperative period and 24 months following surgery, the ODI decreased by 53.86%, the VAS for low back pain decreased by 63.83%, and low back pain with radiculopathy decreased by 60.20%, all statistically significant (p ≤ 0.5). Eighty-two percent of the patients were completely satisfied and 18% were satisfied. There was an average increase in disc height of 12 mm (p &lt;0.001). The range of motion of the affected segment increased by 4° to 7° after surgery (p &lt;0.004). Conclusions: Lumbar arthroplasty of a segment is recommended as an effective treatment for patients with degenerative disc disease with low back pain with or without a root component who meet the inclusion criteria. Level of Evidence III, Systematic reviewb of Level III studies.
