The effect of corporate social responsibility on job pursuit intentions: Contributes from person-organization fit and organizational attractiveness

Previous studies suggest that the corporate social performance of organizations influences their attractiveness as a future workplace (e.g., Gomes & Neves, 2010; Greening & Turban, 2000). People tend to considerer an organization as more attractive when, knowing its socially responsible practices, they perceive higher levels of person-organization fit (Kim & Park, 2011). The present study analyzes how the relation between these variables translates into job pursuit intentions, namely intention to apply for a job vacancy (IAJV). In the research, CSR perception was manipulated in order to observe its effect on IAJV through the mediating effect of perceived person-organization fit and organizational attractiveness. Participants (n = 260) were randomly subjected to two experimental conditions by responding to an electronic questionnaire containing the description of an organization that implements (i.e., the high involvement condition) or not (i.e., the low involvement condition) a set of CSR practices. This was followed by questions about other variables of interest. The results of multiple mediation analyses using PROCESS (Hayes, 2013) support the proposal that CSR indirectly affects participants’ IAJV, through perceived person-organization fit and organizational attractiveness.info:eu-repo/semantics/publishedVersio

More socially responsible, more ethical, more attractive as a future employer? Contributes of corporate social performance and ethical reputation for the attraction of future employees

Previous studies suggest that the corporate social performance of organizations influences their attractiveness as a workplace. This study analyzed additional variables that may help explain this relationship. In this context, an ethical reputation is a construct positively related to corporate social responsibility (CSR). In the research, CSR perception was manipulated in order to observe its effect on organizational attractiveness through the mediating effect of ethical reputation. Participants (n = 260) were randomly subjected to two experimental conditions by responding to an electronic questionnaire containing the description of an organization that implements (i.e., the high involvement condition) or not (i.e., the low involvement condition) a set of CSR practices. This was followed by questions about other variables of interest. The results show that the proposed theoretical model provides a strong fit to the data, thus empirically supporting the proposal that CSR directly and indirectly affects, through ethical reputation, evaluations of organizations as a future workplace. In practical terms, this means that, in the war for talent, organizations can use information about their corporate social performance and ethical reputation to attract potential candidates, alongside more traditional information on organizational attributes and job characteristics.info:eu-repo/semantics/publishedVersio

Tolerância de rizóbio de feijão-caupi à salinidade e à temperatura em condição in vitro.

A seleção de estirpes de rizóbio tolerantes a estresses de salinidade e temperatura, característicos da região semi-árida, arnplia as chances de sucesso para a introdução e estabelecimento de bactérias fixadoras do nitrogênio atmosférico em associação com o feijão-caupi, resultando no aumento da produtividade de grãos. Fatores como tolerância a diferentes concentrações de NaCl (1%,2% e 3%) e dois níveis de temperatura elevada (39°C e 42°C) foram estudados em setenta e seis estirpes de rizóbio, isoladas de nódulos de feijão-caupi, com o objetivo de identificar as relações com a região de origem e habito de crescimento em meio de cultura YEM sólido. De modo geral, observou-se que as estirpes provenientes do Sertão se mostraram mais tolerantes a temperaturas elevadas. O estudo dos efeitos da salinidade (NaCl), por outro lado, mostrou que a medida que a concentração do sal aumenta ha uma redução na porcentagem de estirpes tolerantes, sendo que cerca de 40% delas foram capazes de crescer em meio de cultura contendo 1% de NaCl. Na concentração de 2% de NaCl, 17% do total foram capazes de crescer, sendo que 15% eram provenientes do Sertão e 24% da Zona da Mata. Entretanto, na concentração de 3% de NaCl, apenas 12% das estirpes testadas foram capazes de crescer. Cerca de 10% das setenta e seis estirpes mostraram-se tolerantes as altas temperaturas e aos níveis de NaCl testados, sendo uma oriunda do Agreste, quatro do Sertão e duas da Zona da Mata. The selection of rhizobium strains tolerant to salinity and temperature stress, typically of semi-arid regions, enhances the chance for introducing and establishing the air nitrogen fixing bacteria and cowpea association successfully, resulting in grain yield increases. Effects of factors, such as tolerance to different NaCI concentrations (1%, 2% and 3%) and two levels of high temperature (390 C and 420 C). were studied on seventy-six rhizobium strains isolated from cowpea root nodules in order to identify the relation to the origin region and their growth habit in YEM solid culture medium. In general, it was observed that bacteria from the "Sertão" region were more tolerant to high temperatures. On the other hand, results for the salinity study showed that as the salt concentration increased, the percentage of tolerant strains decreased. About 40% of the strains were able to grow in a culture medium with 1% of NaCl. At 2% of NaCl concentration, 17% of the total strains could grow and, from this amount, 15% came from the "Sertão" region and 24% from "Zona da Mata" region. At 3% NaCI concentration, only 12% of the strains were able to grow. From the 76 strains, around 10% were tolerant to high temperatures and to the NaCl levels used, one of them from the "Agreste" region, four from the "Sertão" resigno and 2 from the "Zona da Mata" region".Parcerias: UNEB

Phenotypic description of cardiac findings in a population of Dogue de Bordeaux with an emphasis on atrial fibrillation

The aim of this study was to describe the clinical phenotype of Dogue de Bordeaux (DdB) referred for cardiac investigation, with particular reference to the prevalence of atrial fibrillation and associated features. Review of canine medical records of two United Kingdom veterinary referral hospitals identified 64 DdB with available echocardiographic and electrocardiographic (ECG)/Holter data. Atrial fibrillation was documented in 25 (39%) dogs and supraventricular tachycardia was recorded in five (7.8%) dogs. In a subset of 34 dogs, excluding congenital heart disease (n = 17), presence of a cardiac mass (n = 7) and non-cardiac neoplasia (n = 6), 19 (56%) dogs had atrial fibrillation, with a median heart rate of 200 beats per min (bpm) on presentation. Atrial fibrillation was inconsistently associated with cardiac chamber remodelling, but was frequently associated with systolic dysfunction (13/19, 68.4%) and right sided atrial or ventricular dilatation (14/19, 73.7%) in dogs with atrial fibrillation in this subset. No dogs in this subset had right sided atrial or ventricular dilatation in the absence of supraventricular arrhythmia or systolic dysfunction. The absence of structural heart disease in some dogs with supraventricular arrhythmias suggests that an underlying primary arrhythmic process might be responsible for initiating remodelling, although a primary cardiomyopathy cannot be ruled out

Soybean glycinin improves HDL-C and suppresses the effects of rosuvastatin on hypercholesterolemic rats.

Background: This study was an investigation of the effects of ingesting a daily dose of isolated glycinin soy protein (11S globulin), in association with rosuvastatin, on the control of hypercholesterolemia in experimental animals. Methods: Male Wistar rats were kept in individual cages under appropriate controlled conditions of temperature, light and humidity. The animals were divided into five groups (n = 9): 1) standard (STD): fed on casein as protein source; 2) hypercholesterolemic (HC): STD plus 1% cholesterol and 0.5% cholic acid; 3) HC+11S: hypercholesterolemic + glycinin (300 mg/kg/day); 4) HC+ROS: hypercholesterolemic + rosuvastatin (10 mg/kg/day); 5) HC+11S+ROS: HC diet, the 11S protein and the drug in the doses given in (3) and (4). The protein and the drug were administered by gavage for 28 days. The results indicated that the addition of 1% cholesterol and 0.5% cholic acid induced hypercholesterolemia in the animals without interfering with their weight gain. Results: A single daily dose of glycinin contributed an additional 2.8% of dietary protein intake and demonstrated its functional role, particularly in raising HDL-C, decreasing triglycerides in the liver and improving the atherogenic index in animals exposed to a hypercholesterolemic diet. Conclusion: Most of the beneficial effects of the isolated treatments disappeared when the drug (rosuvastatin) and the protein (glycinin) were taken simultaneously. The association was shown not to interact additively, as noted in the plasma levels of total cholesterol and non-HDL cholesterol, and in the significant increase of cholesterol in the liver. Studies are in progress to identify the effects of peptides derived from the 11S globulin and their role in cholesterol metabolism

Mixtures of polymers and cholinium-based ionic liquids to tailor the phase diagrams and extraction efficiency of aqueous biphasic systems

Aqueous biphasic systems (ABS) are outstanding alternatives over conventional liquid-liquid extraction processes since it is avoided the use of volatile and hazardous organic solvents (VOCs). ABS are more biocompatible systems formed by two aqueous-rich phases that can be designed by combining different pairs of solutes (polymer-polymer, polymer-salt or salt-salt) above specific concentrations. In the past years, ABS have been studied as powerful techniques for purification, separation and extraction purposes. Ionic liquids (ILs) have been described as interesting fluids towards the development of more sustainable processes. Due to the ILs unique properties, their introduction in ABS led to systems with higher selectivity and extraction performance for a wide plethora of compounds. In fact, it was already shown that ILs allow to overcome the low hydrophilic-hydrophobic range of ABS composed of two polymers or one polymer and one inorganic salt. IL-based ABS formed with polyethylene glycol (PEG) polymers were recently introduced and a successful control of the phase polarities, through the manipulation of the IL chemical structure, was demonstrated. Lately, it was also demonstrated that a new class of natural-derived cholinium-based ILs are capable of undergoing two phase separation by the addition of PEGs with different molecular weights. In the present work, mixtures of PEGs with different molecular weights (400 and 2000 g/mol) were used to ascertain on the formation ability of ABS composed of water and cholinium-based ILs or salts. The results obtained indicate that the formation ability of these ABS increase with the content of PEG2000 over PEG400 (and follow a continuous increase), meaning that a close-fitting control on their phases polarity can be attained. These systems were then evaluated on their performance for extracting a series of alkaloids with different polarities, namely caffeine, theophylline, theobromine and nicotine. In general, the alkaloids partition extent to the most hydrophobic phase (PEG-rich) follows their polarity/hydrophobicity. In summary, it is here demonstrated that mixtures of polymers as phase-forming components of ABS allow to tailor the partition coefficients of different alkaloids and their use in the purification of added-value compounds from biomass extracts is straightforwardly foreseen.publishe
