title: Verticality, Regulatory Focus, and Prices: Who is Able to Get a Good Deal?

description: ABSTRACT The use of the metaphor of verticality may affect consumers’ motivations to perform product price assessments, and the motivational regulatory focus of the individual may have features that contribute to restoring motivation. This study aims to analyze the influence of the verticality metaphor, and of the regulatory focus on price assessments in order to get a good deal. We performed an experimental study with a design 2 (vertical metaphor: physically tall vs. physically short) x 2 (regulatory focus: promotion vs. prevention) between subjects. The results show that the treatment group, with the individuals who consider themselves physically tall and focused on prevention, had the best performance when assessing price in the context of getting a good deal. The originality of this research lies in the identification of the behavioral characteristics of individuals that are able to mitigate changes in people’s motivation when exposed to mental simulations of verticality, in order to get a good deal. In practical terms, the findings make it evident that the decrease in individuals’ motivation for decision making surrounding prices, under the effects of verticality, can be reestablished when they take on surveillance behavior as well as behavior aimed at avoiding mistakes.

title: Patient safety culture: perception of nursing professionals in high complexity institutions

description: ABSTRACT Objectives: to analyze the perception of nursing professionals about patient safety culture in three highly complex hospital institutions. Methods: descriptive and quantitative study with professionals working in care. The Hospital Survey on Patient Safety Culture questionnaire was applied, classifying its dimensions according to the percentage of positive responses (strengthened: ≥75.0%; potential for improvement: &lt;75.0% to&gt; 50.0%; weakened: ≤50.0%). Results: four hundred sixty-seven professionals (79.6%), mostly women (88.4%), nursing technicians/assistants (57.2%), 20 to 39 years (60.8%), less than five years in the institution (57.8%) and exclusive bond (79.2%) participated in the study. Safety culture was considered fragile, seven dimensions assessed as such, highlighting “Openness to communication” and “Non-punitive responses to errors” with &lt;30.0% positive responses. Conclusions: evidence of the need for discussion of the subject and strategies for change that promote quality and safety of care.

title: A longitudinal study of sweet orange flowering with grouped count data

description: ABSTRACT. The orange variety “x11”, which is a spontaneous mutant of the sweet orange, has a short juvenile period with early flowering. The data used in this paper are from a randomized design experiment that aimed to assess the plants' flowering characteristics when grafted onto two different varieties of lemon rootstock. The plants were pruned in each of the four seasons, and on each pruning occasion, the number of branches on each plant was counted and classified into four mutually exclusive flowering categories. The data presented large variability and many zeros. The statistical analysis included the use of generalized linear mixed models with a Bayesian approach. The results showed that flowering is not equal over the seasons, i.e., there are significant differences in the classification of the branches across the four seasons and the two varieties, with interactions between seasonal and branch effects.

title: On Geometrical Characteristics of WC-Co Round Cavities After ED-Machining with Different Grades of CuW Electrodes

description: Abstract Cemented carbides (WC-Co) are difficult to be processed by conventional machining processes. Electrical discharge machining (EDM) appears as an efficient technology to manufacture WC-Co products with high accuracy. In EDM literature no research works investigating the influences of different grades of CuW electrodes on geometrical characteristics when ED-machining the same cemented carbide was found. This work presents an investigation on ED-Machining of cemented carbide (WC-Co) with 10% Co using two grades of coper-tungsten (CuW) electrodes with 65% and 85% of tungsten. ED-Machining experiments were carried out under rough, semifinish and finish regimes with input variables discharge current ie, discharge duration te and pulse interval time to using analysis of variance (ANOVA) based on design of experiments with complete factorial 32. Output variables evaluated were WC-Co workpiece geometrical characteristics 3D surface roughness and round cavities circularity measures. Results showed that ED-Machining regime is the most significant parameter on both WC-Co workpiece circularity and surface roughness measures. Electrodes grades CuW65 and CuW85 presented similar results on workpiece circularity and 3D surface roughness.

title: Analyzing course programmes using complex networks

description: Abstract We analyze the curriculum of the early common-years of engineering in our institute using tools of statistical physics of complex networks. Naturally, a course programme is structured in a networked form (temporal dependency and prerequisites). In this approach, each topic within each programme is associated with a node, which in turn is joined by links representing the dependence of a topic for the understanding of another in a different discipline. As a course programme is a time-dependent structure, we propose a simple model to assign links between nodes, taking into account only two ingredients of the teaching-learning process: recursiveness and accumulation of knowledge. Since we already know the programmes, our objective is to verify if the proposed model is able to capture their particularities and to identify implications of different sequencing on the student learning in the early years of engineering degrees. Our model can be used as a systematic tool assisting the construction of a more interdisciplinary curriculum, articulating between disciplines of the undergraduate early-years in exact sciences.

title: Understanding Solvent/Bixin Interactions by Raman Spectroscopy

description: In this work, Raman spectroscopy and density functional theory (DFT) calculations have been used in order to understand the nature of the interaction between the carotenoid bixin and organic solvents with dielectric constant varying from ca. 2 (toluene) to ca. 47 (dimethyl sulfoxide). Raman shifts registered for the main carotenoid marker band, the C=C stretching mode (1525-1533 cm-1), were used as a probe to monitor spectral changes due to chemical interaction between bixin in the solid state with the analogous solvated species. Raman spectra of bixin in solution showed significant bathochromic shifts in the wavenumber position of ν(C=C) when compared with the solid state. Among the solutions, subtle differences were observed and the polarizability rather than dielectric constant of the solvents seems to be a more appropriate parameter to explain the differences in Raman shifts which could be correlated with the solvation degree of bixin. Correlation between DFT analysis and molecular dynamics simulations obtained for cis-bixin in DMSO and CHCl3 demonstrated that the interaction of the solute with the respective solvents occurs in specific portions of the molecule, however, this result was not confirmed by the experimental data since bixin is solvated by larger numbers of solvent molecules.

title: Benthic macroinvertebrate communities in sites with native forest presence and absence in north Patagonia

description: ABSTRACT The benthic fauna in northern Patagonian streams is characterized by presence of water quality indicator species. The aim of the present study was characterized the benthic communities in streams associated to sites with presence of Nothofagus forests and with human intervention without Nothofagus forests using null models in ecology, unified neutral theory of biodiversity (UNTB) and unweighted pair group method with arithmetic mean (UPGMA). The results of species co-occurrence null model revealed that species associations are random, whereas the results of niche overlap null models revealed the presence of niche overlap. The UNTB results revealed low species number. The results of UPGMA revealed that species composition is specific for each site existing marked differences. The exposed results agree with results observed for central and northern Patagonian Chilean rivers, where the species composition is variable in according to surrounding basin properties and seasonal conditions.

title: Application of inspection methods in reinforced concrete bridges

description: Abstract Pathological manifestations affect buildings in different aggressive environments. Thus, technical inspection actions and occasional interventions are necessary, using specific methodologies that can minimise subjectivity in this process and guarantee adequate solutions regarding durability. This research study applies inspection methodologies to a bridge located in northeastern Brazil. The researchers identified pathological manifestations and elements to be evaluated through the calculation of deterioration with an adapted version of the GDE method (assessment of the degree of structural deterioration), and also through a technical analysis of the DNIT standard. A “high” deterioration degree of 64.03 was obtained, as well as a technical grade of 3, characterising the structure as “potentially problematic”. Experience and technical qualification are crucial in these evaluations; however, the adapted GDE methodology has specificities that reduce subjectivity, enhancing the inspection process and setting the deadlines for eventual repairs. Hence, it was possible to quantify and classify the state of conservation of the structure, indicate the need for intervention and obtain comparisons between bridge inspection methods, ensuring the refinement of results and reproduction in other studies.

title: Vitamin C stability in acerola and camu-camu powder obtained by spray drying

description: Abstract Acerola and camu-camu fruits possess high vitamin C content. However, since these fruits are little consumed in their fresh form, it is important to consider that vitamin C can be oxidized depending on storage conditions. Thus, this study aimed to produce acerola and camu-camu powders by spray drying to maintain the stability of their vitamin C content during storage. Acerola and camu-camu powders were characterized in relation to their physicochemical characteristics, antioxidant activity, and vitamin C concentration and stability under different storage conditions (30 °C and 40 °C, 75% relative humidity). In general, the powders were proven to be stable, with low water activity (&lt; 0.40) and humidity (&lt; 4.0 g/100 g powder), as well as high vitamin C concentrations (1593.2 and 6690.4 mg/100 g of powder for acerola and camu-camu, respectively). Furthermore, we observed a high antioxidant activity by ABTS●+, DPPH• and FRAP assays. The powders stored at lower temperature (30 °C) showed higher vitamin C stability. In conclusion, acerola and camu-camu powders produced by spray drying are potential sources of vitamin C and active compounds and are therefore suitable for several food industry applications.

title: Furfural Hydrodeoxygenation over a Ruthenium-Based Bifunctional Catalyst in the Presence of a Direct Source of H2

description: This work presents the results obtained for the gas chromatography-mass spectrometry (GC-MS) monitoring of the liquid-phase hydrodeoxygenation (HDO) reaction of furfural (FFR) to 2-methylfuran (MF) over a bifunctional Ru/RuOx/C catalyst in the presence of a direct source of H2. Hydrogenation and hydrogenolysis reactions of FFR and of the intermediate furfuryl alcohol (FA), respectively, were independently studied to provide insights on the HDO mechanism. The mass spectra monitoring of the kinetic isotope effect indicated the HDO reaction occurs through a two-step mechanism comprising of an initial ruthenium-mediated hydrogenation reaction of FFR to FA. In the second step, the FA thus formed experiences a hydrogenolysis reaction via ring activation where the hydrogen atoms are firstly attached to the C3 carbon generating a ring activated structure and removing the OH group. The observation of the peaks at m/z 85 and 84 in the mass spectrum of the MF product confirms this reaction pathway.

title: THE ANTECEDENTS OF RECOGNIZE THE VALUE IN THE ABSORPTIVE CAPACITY

description: ABSTRACT Purpose: The ability of individuals to recognize the value of external, corporate-applicable information is critical to organizational absorptive capacity. This study aims to define and operationalize the recognize the value construct, identify its antecedents and predictive power. Originality/value: It analyzes how this construct occurs at the level of the individual, workgroups and processes, besides indicating its relationship with the other predictors present in the literature. The theoretical bases can be classified by Cohen and Levinthal (1990) and Zahra and George (2002). The first one considers absorptive capacity as a stock of knowledge, the second one, as dynamic capacity. Design/methodology/approach: We adopt the Structural Equation Modeling technique to test a variance model, with four predictors of general recognize the value. We use a non-probabilistic sample consisting of 283 individuals who answered an electronic questionnaire. Findings: The results are satisfactory, as the model shows a 40% prediction power of how recognize the value occurs. The work processes were found to show higher predictive power (β = 0.417), meaning that that processes of recognize the value are enablers of the organizational recognize the value of new information. The other hypotheses were also supported, but with comparatively minor effects. The study is limited to the identification and analysis of the effects of predictors and does not contemplate its consequences, whose research is suggested.
