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.

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: Dextrorotatory Chromomycins from the Marine Streptomyces sp. Associated to Palythoa caribaeorum

description: A Streptomyces sp. (BRA-384) was selected among nine strains of bacteria isolated from the zoanthids Palythoa caribaeorum due to the high cytotoxic activity presented by its EtOAc extract (inhibitory concentration mean (IC50) of 2 ng mL-1) against colon cancer cell line. From the EtOAc extract of BRA-384 three new chemical entities (A6, A7 and A8) and one dextrorotatory chromomycin (A5), a promising class of anticancer compounds, were identified. The cytotoxicity of chromomycins A5 to A8 was tested against five tumor cell lines (HCT 116 (human colon adenocarcinoma), MCF-7 (human breast carcinoma), PC-3M (human metastatic prostate cancer), 501-mel (human metastatic melanoma) and MM200 (metastatic melanoma)). All chromomycins were highly potent showing IC50 values from 0.2 to 133 nM. Chromomycin A5 was consistently the most potent over all tested cells (IC50 values from 0.2 in MM200 to 7.9 nM in PC-3M), inclusive when compared to the standard chemotherapeutic agent doxorubicin, that presented IC50 values ranging from 147 to 568 nM against MM200 and MCF-7, respectively.

title: Brazilian validation of the item banks on Sleep Disturbance and Wake Disturbance in the Patient-Reported Outcomes Measurement Information System (PROMIS)

description: This study aimed to validate the Brazilian version of the item banks for Sleep Disturbance and Wake Disturbance from the Patient-Reported Outcomes Measurement Information System (PROMIS). Validation of these item banks used classical test theory, item response theory, calibrations of items according to the gradual response model proposed by Samejima, and analysis of Differential Item Functioning (DIF), with a sample consisting of 627 participants over 18 years of age. As for data quality, there were no missing data, five items from the Sleep Disturbance bank and four items from the WE bank showed a floor effect, and none of the banks showed a ceiling effect. The two banks displayed excellent reliability with homogeneous scale and good temporal stability. With confirmatory factor analysis, using absolute and incremental goodness-of-fit indices, both banks displayed good fit, showing that the instruments are valid and sufficiently unidimensional. The calibration showed that the items’ psychometric properties were satisfactory with good coverage of the sleep-wake construct. As for DIF, both the Sleep Disturbance and Wake Disturbance banks proved to be homogeneous for the different test groups. In conclusion, the version in Brazilian Portuguese for the item banks on Sleep Disturbance and Wake Disturbance in the PROMIS proved to be a reliable, precise, and valid instrument with robust psychometric analyses.

title: PACING STRATEGY IN SPEED SKATING: INFLUENCE OF THE GENDER AND RACE'S PERFORMANCE LEVEL IN 1500-M DISTANCE

description: ABSTRACT Our aim was to analyze the pacing strategy adopted during middle-distance speed skating and to verify the influence of gender and race's performance level on pacing adopted. The races of male and female athletes during five stages of a World Cup, season 2009/2010, were included in the study. In both genders, the races were classified as high (HP) and low (LP) performance. The pacing adopted was similar between genders, with male athletes being faster throughout the race (P &lt; 0.05). In both genders, the HP races were more aggressive in all intervals compared to LP races (P &lt; 0.05), regardless of gender. Although performance is different between genders, the pacing adopted was similar between them in faster and slower races, suggesting that the technical in elite athletes seems to be a determinant factor in choice of adopted pacing strategy.

title: Corporate Social Responsibility and labor relations: a research agenda about internal stakeholders management in UN’s global compact signatory corporations

description: ABSTRACT Literature often presents the concept of Corporate Social Responsibility (CSR) in association with the idea of Business Ethics. In this article, we saw the need to ellaborate a theoretical model of Business Ethics that was capable of guiding research on Corporate Social Responsibility practices aimed at organizations’ internal public. To this end, we analyzed different Business Ethics fields - namely Responsibility Ethics, ethics that reaffirm the principle of humanity and ethics that generate conventional morality, so as to avoid automatic associations with the idea of Corporate Social Responsibility. The theoretical dialogue of these two major constructs (Business Ethics and CSR) with the field of Labor Relations is dealt with in accordance with these three dimensions of ethics. To find out how a company that desires to be socially responsible relates to its employees, there are indicators that are strongly related to key aspects of labor relations, as shown by the UN’s Global Compact Agenda. This interface produced the methodological guidelines that conducted research data collection and analysis, pointing out important challenges in this agenda, as well as serving as a basis for further studies in this field.

title: Microbiological Attributes of Soil Under Spontaneous Restoration

description: ABSTRACT The aim of this study was to evaluate the effect of vegetation on soil microbial activity during spontaneous restoration and the effect of remaining eucalypts on the restoration stage of reserve ranges installed in eucalypt plantations. The studied areas were in the following stages: initial restoration stage with and without remaining eucalypts; advanced restoration stage with and without remaining eucalypts. Areas of Cerrado, native forest and commercial eucalypt plantation (Eucalypts) were evaluated for reference. Principal component analysis detected the following groups: 1- Cerrado and areas in initial restoration stage with or without eucalypts and areas in advanced restoration stage without eucalypts; 2- areas in advanced restoration stage with eucalypts; 3- native forest; 4- Eucalypts. The restoration areas are at intermediate stage of recovery, slightly superior to the advanced stage. Basal respiration, organic and microbial soil carbon and microbial and metabolic quotients were more similar to those observed in Cerrado than in eucalypt cultivation areas and little influence of the remaining eucalypts plants was observed.

title: Central precocious puberty: revisiting the diagnosis and therapeutic management

description: ABSTRACT Clinical and laboratory diagnosis and treatment of central precocious puberty (CPP) remain challenging due to lack of standardization. The aim of this revision was to address the diagnostic and therapeutic features of CPP in Brazil based on relevant international literature and availability of the existing therapies in the country. The diagnosis of CPP is based mainly on clinical and biochemical parameters, and a period of follow-up is desirable to define the “progressive” form of sexual precocity. This occurs due to the broad spectrum of pubertal development, including isolated premature thelarche, constitutional growth and puberty acceleration, progressive and nonprogressive CPP, and early puberty. Measurement of basal and stimulated LH levels remains challenging, considering that the levels are not always in the pubertal range at baseline, short-acting GnRH is not readily available in Brazil, and the cutoff values differ according to the laboratory assay. When CPP is suspected but basal LH values are at prepubertal range, a stimulation test with short-acting or long-acting monthly GnRH is a diagnostic option. In Brazil, the treatment of choice for progressive CPP and early puberty is a long-acting GnRH analog (GnRHa) administered once a month or every 3 months. In Brazil, formulations of GnRHa (leuprorelin and triptorelin) are available and commonly administered, including 1-month depot leuprorelin 3.75 mg and 7.5 mg, 1-month depot triptorelin 3.75 mg, and 3-month depot leuprorelin 11.25 mg. Monthly or 3-month depot GnRHa are effective and safe to treat CPP. Arch Endocrinol Metab. 2016;60(2):163-72

title: MODELLING APPROACH FOR PREDICTING LANDSCAPE CHANGES IN EXPANDING EUCALYPTUS PLANTATIONS IN BRAZIL

description: Abstract This paper combines remote sensing, environmental modeling, and landscape ecology to investigate the impacts of the expansion of eucalyptus reforestation. Using these techniques, a methodology was developed to analyze and predict future land cover and landscape structure trends. The study area was comprised of the river basin municipalities in Rio Piracicaba and the metropolitan region of Vale do Aço (RMVA), a region that is home to large steel, paper, and cellulose industries in Minas Gerais. This major hub of economic development in the state has altered the landscape through deforesting native vegetation and planting eucalyptus trees. Land cover data were taken from satellite image classifications (TM/Landsat) from 1985, 2010 and 2013 in order to study the land cover changes. A number of variables that stimulate or restrict these alterations and the eucalyptus expansion observed between 1985 and 2010 were used to simulate the eucalyptus expansion, through Multi-Layer Perception Neural Networking. The results showed that the areas of Eucalyptus reforestation increased by about 12% between 1985 and 2010, whereas forest areas contracted by approximately 9%, and pasture by 3%. The simulated eucalyptus expansion indicated that by 2035 the structure of the landscape will have changed, with an increased level of isolation of the forest patches and a decrease in their nuclear area.
