title: Delivering bad news to patients from the perspective of medical students

description: Abstract The objective of this study is to verify if medical students acquired knowledge about delivering bad news to patients during their undergraduate clinical courses. A questionnaire was applied to two groups: Group 1, which had not studied the theme and Group 2, which had already studied it. 29.41% of Group 1 knew about the Spikes Protocol and 100% of Group 2 (p=0.0001) knew about it. 25.88% of Group 1 and 81.01% of Group 2 (p=0.0001) were partially prepared for communication. 17.65% of Group 1 and 83.54% of Group 2 (p=0.0001) felt more secure after the study. 90.59% of Group 1 attributed a maximum grade to the importance of learning and 87.34% of Group 2 (p=0.8166) did the same. It was concluded that all students recognized the importance of learning about delivering bad news and the wide difference of knowledge in favor of Group 2 highlights the effectiveness of its approach during undergraduation.

title: Phase Separation and Development of the Microstructure for Stainless Steel to Copper Alloy Weld Joints Using a Fiber Laser

description: ABSTRACT Stainless steel and copper alloys joints are often applied in aerospace, marine and power industries where both high thermal and electrical conductivity (Cu) and corrosion resistance (steel) are required. In the aerospace industry, in particular for the combustion chamber of rocket engines, copper and steel combinations offer perfect materials selection due to their combined high thermal conductivity and good stiffness. In this work, laser welds were produced with intensity between 3.8 × 104 and 5.7 × 104 W/mm2 and a heat input between 72 and 108 J/mm, giving an aspect ratio of 1.8. The microstructure of the weld beads was marked by chemical heterogeneities due to the phase separation between Cu and Fe in the liquid state. The phase separation gave rise to globular precipitates which further transform due to a secondary precipitation at temperatures below 1000 °C. The steel side part of the weld presents around 20% Cu, leading to a liquation of the grain boundaries and cracking at high heat inputs. The hardness values situated between both base materials and the tensile shear behavior, when the weld is sufficiently tough, present strength up to 350 MPa and elongation up to 10%.

title: Migration and Labor in the United States. Occupational polarization and racialization of social inequality in post-crisis age

description: Abstract We analyze the insertion of the Latin American immigrants in the labor market of the United States in a post-crisis scenario. Our thesis is that two structural processes determine the labor situation of migrants: (i) the polarization of the structure of occupations, and (ii) the racialization of class structure and social inequality. Racism and ethnic discrimination have always been part of the social structure of the United States, what is relevant in today's age is the size and magnitude they reach, as well as the trends that are estimated for the next decades.

title: MORPHOLOGY AND PRODUCTION OF WEST INDIAN CHERRY IRRIGATED WITH SALINE WATERS UNDER COMBINATIONS OF NITROGEN-POTASSIUM FERTILIZATION

description: ABSTRACT Fertilization management is one of the technologies studied to reduce nutritional imbalance in plants submitted to saline stress. In this context, we analyzed the effect of the combination of nitrogen and potassium fertilization on the morphology and production of West Indian cherry irrigated with saline waters in the first year of cultivation. The experiment was carried out in the CCTA/UFCG, in 60-L lysimeters installed in the field, in a randomized block design and 5 x 4 factorial scheme, referring to five levels of irrigation water salinity (ECw), i.e., 0.3, 1.3, 2.3, 3.3, and 4.3 dS m-1, and four combinations (C) of nitrogen-potassium fertilization, i.e., C1 = 70% N + 50% K2O; C2 = 100% N + 75% K2O; C3 = 130% N + 100% K2O, and C4 = 160% N + 125% K2O of the recommended dose for West Indian cherry, with three replicates and one plant per plot consisting of a lysimeter. The cv. ‘Flor Branca’, grafted on cv. Junco, was studied. The combination of fertilization with 70% N + 50% K2O promoted higher morphology and production values and mitigated the effect of salinity on fruit diameter up to an ECw of 1.3 dS m-1. Nitrogen-potassium fertilization in the combination of 130% N + 100% K2O impaired plant morphology and production. The ECw above 0.3 dS m-1 decreased the stem diameter, size, and average weight of fruits of West Indian cherry in the first year of cultivation.

title: Qualification of care in oral health services

description: Abstract Introduction This study aimed to analyze the quality of care in oral health services regarding its responsiveness to users’ needs. Methodology This cross-sectional and quantitative study included users of the public dental service in the context of Primary Health Care (PHC) in municipalities of three different Brazilian states (n = 1312). Data collection occurred through interviews within health facilities. The study included 15 variables related to the reception process, which were preliminarily analyzed with chi-square tests. The variables associated with the outcome 'responsiveness to users’ needs' were analyzed through logistic regression and feature selection test. Results Negative assessments of full attention to users’ needs were significantly associated with: care provided by the dental surgeon and staff; willingness to discuss doubts, concerns and oral health problems; initial receptivity in the PHC dental service; and provision of information on oral health in the PHC. The other variables were not significantly associated with the outcome variable after the feature selection test. Conclusion the quality of reception in oral health services is significantly related to the humanization of care, responsiveness of dentists and staff and the processes of listening and providing guidance.

title: Relational structure in the global automotive industry: groups, networks and fields

description: Abstract Purpose: The purpose of this study was to analyze the network structure of automotive companies linked by cross-shareholding, joint ventures, manufacturing contracts and alliances, from 2004 to 2012. The study also explored how the network structure affects the competition in the field. Design/methodology/approach: The sample involved 3695 dyads. Based on this data, it was possible to build and assess networks using Gephi and UCINET software. The study considered network analysis metrics such as centrality, group and network densities temporally. Thus, associated with a contextual and longitudinal analysis, the construction of sociograms allowed visualization of the interactional structure and the automakers’ position in the field. Findings: Results showed that the internationalization and growth of automakers and suppliers are made possible through these relationships among companies (cross-shareholding, joint ventures, manufacturing contracts and alliances). Connections may generate greater power, access to resources and market opportunities. It also enhanced the elaboration of inferences about how these resources influence the competition in the field. Originality/value: The increasing importance of this relational resource shapes the industry competitive structure, which is composed of cooperative and competitive relationships found in meso-level orders.

title: MATTER ACCUMULATION AND PHOTOSYNTHETIC RESPONSES OF MACAW PALM TO CYCLICAL DROUGHT

description: ABSTRACT The objective of this work was to evaluate the plant-water relations, photosynthetic parameters and growth of macaw (Acrocomia aculeata (Jacp.) Lodd. ex Mart.) plants, thus, ten plants were subjected to three successive drought and rehydration cycles and ten other plants were irrigated normally as control. The drought cycles consisted of a suspension of irrigation until the net CO2 assimilation rate (A) reach values lower than 5% of the control, and a rehydration until a plants recover at least 85% of A of the control plants. Reductions in A, stomatal conductance (gs ) and transpiration (E), above 95%, were found with predawn leaf water potential (Ψpd) of -1.85 MPa. After rehydration, the gs and E of plants with and without water stress was not different, however, A presented a significant difference. Leaf water potentials below -0.5 MPa reduced the intracellular and atmospheric CO2 ratio and increased water use efficiency, and values of -1.85 MPa, when both showed an increase and decrease, respectively. The reduction of A and gs was linear and proportional to Ψpd. Total dry matter accumulation reduced by 50% in the plants subjected to drought. The cyclic water stress resulted in reduction of gas exchange and matter accumulation in macaw palm plants; a stomatal limitation of A occurred until Ψpd of -1.85 MPa, and then a non-stomatal limitation.

title: Calligraphic Body, Voice: The Performance Writings of Manoel Ricardo de Lima and Sérgio Medeiros

description: Abstract This article deals with the works of two contemporary Brazilian writers, Manoel Ricardo de Lima and Sérgio Medeiros, seeking to define, through the analysis of their work, what today may be called a “performatic” trace in contemporary literature. The main characteristics of these performatic writings would include the presence of the body in writing, together with the intermingling and indistinction of artistic genres. Paul Zumthor’s concept of “performance” followed by readings of Artaud, Beckett and Hans-Thies Lehman are used to think through Lima and Medeiros’ work in light of a “performatic literature.”

title: Effect of finishing and polishing on color stability of a nanofilled resin immersed in different media

description: OBJECTIVE: The purpose of this study was to evaluate the effect of finishing and polishing on color stability of a nanofilled composite resin (Filtek Z350 XT) according to different immersion media.MATERIAL AND METHOD: Composite disks (10 mm diameter, 2 mm thickness) were prepared for each group (n = 6) using a stainless steel mold. The groups were divided according to the presence or absence of finishing and polishing procedure and immersion media (artificial saliva, artificial juice- KAPO(r) Coca-Cola(r)flavors: pineapple, orange, strawberry and grape). The finishing and polishing procedures were performed using Super -Snap(r) disks. The specimens were stored in artificial saliva for 24 hours (baseline) and were analyzed using a color spectrophotometer by CIELab system. Then, they were immersed in different media for 5 minutes, 3 times a day, every 4 hours during 60 days. They were stored in artificial saliva at 37 ± 1°C during the immersion intervals. After this time, new measure of color was performed. The data were analyzed using Kruskall-Wallis test and Mann- Whitney test. The significance level was 5%.RESULT: The results showed that the finishing/polishing not significantly influence the color stability of resin composite (p &gt; 0.05). There was no statistically significant difference in the color stability of the studied resin after immersion in different media (p &gt; 0.05).CONCLUSION: The finishing and polishing procedures and the immersion media did not have influence on color stability of nanofilled resin Filtek Z350 XT.

title: Heterotopias of writing and literary displacements

description: Abstract In this paper, we propose an approach to literature produced in heterotopic spaces (Foucault, 2015), where the word emerges unexpectedly. The focus of the paper is to investigate what diverts this kind of literature from established spaces, from a political approach, calling into question divisions and hierarchies in the distribution of the sensible (Rancière, 2009). We examine the universe of this writing in the collection Exercícios de uma escrita menor: um olhar atelial (Farina; Garavelo; Fonseca, 2014), a set of texts produced by patients at the Hospital Psiquiátrico São Pedro, in Porto Alegre.
