The impact of corporate social responsibility on the Peruvian consumer’s purchasing behavior

This exploratory research aims to find out the extent to which Corporate Social Responsibility (CSR) impacts the purchasing behavior of Peruvian consumers when it comes to convenience food products. The study includes qualitative and quantitative analysis. Qualitative analysis consists of in-depth interviews with CSR representatives from consumer product companies, CSR practitioners and some consumers from the quantitative sample. That group’s composition was selected in order to obtain a wide picture of the consumers’ perception towards CSR, including their understanding of the concept and the relevance in their decision making process when buying convenience food products. The quantitative analysis portion consists of an on-line survey focused on Peruvian consumers who live in Lima during the year 2015. Consumers included in the sample were selected by convenience. After analyzing the 134 completed surveys, the results obtained suggest that even though there is an increasing interest in CSR, including CSR as an attribute of the purchased goods, interest is not fully demonstrated by the purchasing behavior of consumers. The main breach leading to this inconsistency appears to be the lack of or failure in the companies’ CSR communication towards consumers. Consumers demand reliable information which socially responsible companies usually provide; however at this stage, the target audiences of such information are mostly corporations and communities surrounding the manufacturing plants of convenience food products.

The impact of social security reform on occupational and retirement behavior : a quantitative assessment for Brazil

Population ageing is a problem that countries will have to cope with within a few years. How would changes in the social security system affect individual behaviour? We develop a multi-sectoral life-cycle model with both retirement and occupational choices to evaluate what are the macroeconomic impacts of social security reforms. We calibrate the model to match 2011 Brazilian economy and perform a counterfactual exercise of the long-run impacts of a recently adopted reform. In 2013, the Brazilian government approximated the two segregated social security schemes, imposing a ceiling on public pensions. In the benchmark equilibrium, our modelling economy is able to reproduce the early retirement claiming, the agents' stationary distribution among sectors, as well as the social security deficit and the public job application decision. In the counterfactual exercise, we find a significant reduction of 55\% in the social security deficit, an increase of 1.94\% in capital-to-output ratio, with both output and capital growing, a delay in retirement claims of public workers and a modification in the structure of agents applying to the public sector job.

Colony defensive behavior by the social wasp Polybia (Trichothorax) sericea (Hymenoptera, Vespidae)

This work aimed at evaluating the aggressive response of Polybia sericea, incited by mechanical means, as well as collecting information on the biological and population parameters of this species in Caatinga environments. There were positive correlations (P < 0.05) between the number of aggressors and the number of eggs, larvae and adults present in the nests. These results showed that the magnitude of the defense response exhibited by P. sericea is proportional to the energetic investment carried out by the colony in making young forms. The positive significant correlation between the number of aggressors and the total number of adults of the colony corroborates the hypothesis that colonies with a large population of adults have greater potential to perform what is called defensive altruism.

Male behavior in colonies of the social wasp Polistes lanio (Hymenoptera, Vespidae)

Sixteen post-emergent colonies of Polistes lanio were studied while producing males in the course of the colonial cycle. Individually, they remained in the nest only 10.5 days (5-31, n=165). Twelve different male behaviors were observed: remaining immobile on the nest (82,8%), giving alarm (4,8%), flying out from the nest (2,4%), copulating on the nest (2,4%), being dominated (1,6%), self-grooming (1,2%), checking cells (1,2%), adult-adult trophallaxis (receiving food) (0,8%), larva-adult trophallaxis (0,8%), chewing prey and giving it to the larvae (0,8%), returning to the nest without food (0,8%), and fanning the nest (0,4%). In comparison to the behavioral repertory of females (28 items), they performed fewer tasks and remained immobile most of the time on the nest. Their behavior was largely related to self maintenance, but also included giving chewed prey to the larvae, giving alarm signals and fanning the nest.

Voltammetric behavior of nitrofurazone and its hydroxymethyl prodrug with potential anti-chagas activity

Chagas' disease is a serious health problem for Latin America. The situation is worsened by the lack of efficient chemotherapy. The two available commercial drugs, benznidazole and nifurtimox, are more effective in the acute phase of the disease. Nitrofurazone is active against Trypanosoma cruzi, however its high toxicity precludes its current use in parasitosis. Hydroxymethylnitrofurazone is a prodrug of nitrofurazone. It is more active against Trypanosoma cruzi than nitrofurazone, besides being less toxic. This work shows the voltammetric behavior of nitrofurazone and a comparison with those of metronidazole and chloramphenicol using cyclic, linear sweep and differential pulse voltammetries. For these drugs also the prediction of the diffusion coefficients using Wilke-Chang equation was performed. The reduction of nitrofurazone is pH-dependent and in acidic medium the hydroxylamine derivative, involving four electrons, is the principal product formed. In aqueous-alkaline medium and with a glassy carbon electrode pre-treatment the reduction of nitrofurazone occurs in two steps, the first involving one electron to form the nitro-radical anion and the second corresponding to the hydroxylamine derivative formation. Hydroxymethylnitrofurazone presented the same voltammetric behavior and electroactivity, indicating that the molecular modification performed in nitrofurazone did not change its capacity to be reduced. A brief discussion regarding the differences in biological activity between the two compounds is also presented. ©2005 Sociedade Brasileira de Química.

The behavior and natural history of Chartergellus, a little-known genus of neotropical social wasps (Vespidae Polistinae Epiponini)

This study reviews published data on the behavior and natural history of Chartergellus and presents the first observations on social interactions in this genus of tropical swarm-founding wasps. Observations of Chartergellus golfitensis in Costa Rica and C. punctatior in Colombia showed that queens perform a post-oviposition egg-guarding vigil, and a bending display like that characteristic of epiponine social wasps that lack consistent morphological differences between workers and queens and have caste determination in the adult stage. Young, old, and queen (egg-laying) females of C. golfitensis showed small differences that indicate color changes with age, and structural differences that could be due to seasonal or colony-cycle changes in developmental conditions, but do not rule out the possibility of pre-adult caste determination, a phenomenon that needs to be carefully distinguished from pre-adult caste bias. Sexual dimorphism and the behavior of males at the nest in C. golfitensis is described, as well as the aggressive and avoidance behavior of females toward males. Nest structure in both species is as described previously for Chartergellus species, but some anomalies and their possible evolutionary significance are discussed. Cell initiation by an egg-laying queen, a behavior never seen by workers, and by a young female with slightly developed ovaries, may be vestiges of ancestral solitary reproductive traits where developed ovaries are associated with cell construction. © 2010 Dipartimento di Biologia Evoluzionistica dell'Università, Firenze, Italia.

Adesão ao tratamento anti-retroviral por cuidadores de crianças e adolescentes soropositivos de uma Unidade de Saúde do Estado do Pará

O tema da adesão ao tratamento tem recebido muita atenção dentro da Psicologia da Saúde nos últimos anos. Estudos nessa área revelam que os pacientes que não aderem ao tratamento podem não se beneficiar dos ganhos trazidos pela intervenção terapêutica. A literatura sobre adesão ao tratamento anti-retroviral revela que é o cuidador que geralmente assume a responsabilidade pelo gerenciamento do tratamento de crianças e adolescentes soropositivos. O objetivo principal do presente estudo foi descrever o padrão de adesão ao tratamento de cuidadores de crianças e adolescentes soropositivos que vivem no Estado do Pará, identificando as variáveis que interferem na adesão. Buscou-se, ainda, revelar os tipos de estratégias de enfrentamento utilizadas para lidar com as condições adversas trazidas pela soropositividade. Para tanto, realizou-se um estudo descritivo, de corte transversal, com 30 cuidadores, matriculados na Unidade de Referência Materno-Infantil e Adolescente do Estado do Pará (UREMIA), utilizando como instrumentos de coleta de dados, junto aos cuidadores, um roteiro de entrevista que investigava aspectos sociodemográficos, clínicos e psicossociais das crianças e adolescentes e a Escala Modos de Enfrentamento de Problemas (EMEP). Em relação à adesão pelos cuidadores, observou-se que algumas condições facilitaram o seguimento do tratamento. Essas condições estiveram relacionadas a variáveis de organização familiar (como o número de pessoas que moravam na residência), à história de interrupção do tratamento e ao auto-relato dos cuidadores sobre o padrão de desempenho a ser emitido mediante o sucesso (ou insucesso) da adesão. A influência dessas variáveis demonstrou a influência do controle do comportamento mediante regras, pois os cuidadores emitiram o desempenho classificado como adesão para evitar entrar em contato com as conseqüências aversivas do não seguimento do tratamento. Em relação às estratégias de enfrentamento, foi demonstrada maior média para o Fator 3, demonstrando a ênfase no uso de estratégias focalizadas em práticas religiosas e/ou pensamentos fantasiosos. Este trabalho propôs que os cuidadores da amostra lidaram com o problema da soropositividade de maneira a esquivar-se de pensar no problema do modo como ele realmente se constituiu diante dos mesmos, utilizando pensamentos religiosos ou mágicos para continuar lidando com a rotina diária de enfrentamento das questões que envolviam a condição de soropositividade da criança e/ou do adolescente. A partir dos dados encontrados, indica-se a realização de estudos que investiguem questões relacionadas ao papel exercido por contingências sociais sobre o comportamento dos cuidadores de crianças e adolescentes que vivem no Pará, bem como a investigação sobre aspectos relacionados à revelação do diagnóstico.

Representações sociais sobre a Aids e a Terapia Anti-Retroviral: influências no tratamento de pessoas vivendo com HIV/Aids

Com o advento da Terapia Anti -Retroviral, a Aids assumiu características de doença crônica, em especial nos países onde o acesso aos medicamentos é efetivamente garantido. O Brasil é tomado como modelo por possuir um programa que tem dado boas respostas à epidemia. Em novembro de 1996, foi promulgada, pelo Sistema Único de Saúde (SUS), a lei que dispõe sobre a obrigatoriedade do acesso gratuito a todos os que necessitarem de medicamentos anti -retrovirais. Os resultados obtidos com o tratamento – a redução progressiva da carga viral e a manutenção e/ou restauração do funcionamento do sistema imunológico – têm sido associados a benefícios marcantes na saúde física das pessoas soropositivas e permitido que elas retomem e concretizem seus projetos de vida. Porém, o acesso universal aos medicamentos que possibilita o tratamento para portadores do HIV gratuitamente ainda enfrenta problemas de adesão. Em uma compreensão mais restrita, adesão pode ser definida como o comportamento de uma pessoa – tomar remédio, seguir uma dieta ou fazer mudanças no estilo de vida – que corresponde às recomendações da equipe de saúde. Nesse contexto, esse estudo se propõe a analisar as representações sociais de sujeitos soropositivos sobre o tratamento anti-retroviral e suas implicações no processo de adesão a este tratamento, caracterizando as imagens e os sentidos que estes sujeitos soropositivos que aderiram ou não aderiram à terapia anti -retroviral possuem sobre este tipo de tratamento e as implicações na sua vida, destacando as objetivações e as ancoragens que compõem suas representações sociais. A metodologia foi pautada nas formulações teóricas sobre pesquisa qualitativa, priorizando -se a entrevista no enfoque do Método de Explicitação do Discurso Subjacente (MEDS), realizadas na Unidade de Referência em Doenças Infecciosas e Parasitárias Especiais (UREDIPE), vinculada à Secretaria de Estado de Saúde do estado do Pará (SESPA) e no Hospital Universitário João de Barros Barreto (HUJBB), mais especificamente na Clinica de Doenças Infecciosas e Parasitárias (DIP).

Behavior of SD-OCT-detected hyperreflective foci in the retina of anti-VEGF-treated patients with diabetic macular edema

Hyperreflective foci (HFs) are observable within the neurosensory retina in diabetic macular edema (DME) using spectral domain optical coherence tomography (SD-OCT). HFs have also been seen in wet age-related macular degeneration (AMD), although the origin is still unknown; however, they reduced significantly during anti-VEGF (vascular endothelial growth factor) therapy, and their baseline amount seemed to correlate with treatment success. In this study the behavior of HFs was evaluated during anti-VEGF therapy for DME.
