Expanding understanding of service exchange and value co-creation: A social construction approach
According to service-dominant logic (S-D logic), all providers are service providers, and service is the fundamental basis of exchange. Value is co-created with customers and assessed on the basis of value-in-context. However, the extensive literature on S-D logic could benefit from paying explicit attention to the fact that both service exchange and value co-creation are influenced by social forces. The aim of this study is to expand understanding of service exchange and value co-creation by complementing these central aspects of S-D logic with key concepts from social construction theories (social structures, social systems, roles, positions, interactions, and reproduction of social structures). The study develops and describes a new framework for understanding how the concepts of service exchange and value co-creation are affected by recognizing that they are embedded in social systems. The study contends that value should be understood as value-in-social-context and that value is a social construction. Value co-creation is shaped by social forces, is reproduced in social structures, and can be asymmetric for the actors involved. Service exchanges are dynamic, and actors learn and change their roles within dynamic service systems

Preliminary investigation of Culicidae species in South Pantanal, Brazil and their potential importance in arbovirus transmission Investigação preliminar das espĂ©cies de culicĂdeos do Pantanal Sul brasileiro e sua potencial importância na transmissĂŁo de arbovĂrus
In view of the high circulation of migratory birds and the environmental and climatic conditions which favor the proliferation of arthropods, the Brazilian Pantanal is susceptible to circulation of arboviruses. However, the amount of data concerning arbovirus vectors in this area is scarce; therefore the aim of this study was to conduct a preliminary investigation of Culicidae species in the Nhecolândia Sub-region of South Pantanal, Brazil and their potential importance in the arbovirus transmission. A total of 3684 specimens of mosquitoes were captured, 1689 of which caught in the rainy season of 2007, were divided into 78 pools and submitted to viral isolation, Semi-Nested RT-PCR and Nested RT-PCR, with a view to identifying the most important arboviruses in Brazil. Simultaneously, 70 specimens of ticks found blood-feeding on horses were also submitted to the same virological assays. No virus was isolated and viral nucleic-acid detection by RT-PCR was also negative. Nevertheless, a total of 22 Culicidae species were identified, ten of which had previously been reported as vectors of important arboviruses. The diversity of species found blood-feeding on human and horse hosts together with the arboviruses circulation previously reported suggest that the Nhecolândia Sub-region of South Pantanal is an important area for arbovirus surveillance in Brazil.<br>Regiões como o Pantanal brasileiro, que apresentam fatores como riqueza de fauna silvestre incluindo circulação de aves migratĂłrias e condições ambientais e climáticas favoráveis Ă proliferação de artrĂłpodes estĂŁo potencialmente sujeitas Ă circulação de arbovĂrus. Entretanto, poucos trabalhos foram realizados acerca da presença de arbovĂrus em potenciais vetores no Pantanal. Neste sentido o principal objetivo deste trabalho foi conduzir uma investigação preliminar para presença de arbovĂrus em amostragens de culicĂdeos capturados na Sub-regiĂŁo da Nhecolândia no Pantanal Sul. Um total de 3684 mosquitos foi capturado, dos quais 78 grupos compondo uma amostragem de 1789 espĂ©cimes foram submetidos Ă s tĂ©cnicas de isolamento viral e RT-PCR para os mais importantes arbovĂrus no Brasil. Simultaneamente, 70 espĂ©cimes de carrapatos capturados durante hematofagia em cavalos tambĂ©m foram submetidos Ă pesquisa viral. NĂŁo houve isolamento viral em nenhuma amostra analisada e os resultados de detecção de ácido nuclĂ©ico viral foram tambĂ©m negativos. Entretanto, foram identificadas 22 espĂ©cies de culicĂdeos, dez das quais previamente reportadas como vetores de importantes arbovĂrus. A competĂŞncia vetorial de espĂ©cies capturadas durante hematofagia em humanos e cavalos aliada ao relato prĂ©vio de circulação de arbovĂrus sugerem a Sub-regiĂŁo da Nhecolândia como uma importante área de vigilância para arbovĂrus no Centro-Oeste do Brasil

The interrelationships between television viewing, values and perceived well-being: A global perspective
Do global marketing efforts, for example, those using television as a medium, impact on the values and life satisfaction of people, and, if so, is the process similar or different in various regions of the world? We empirically examine the relationship between television viewing, core values (i.e., religiosity and materialism), and perceived well-being factors (e.g., perceived socioeconomic status and relative life satisfaction). Data collected from the Western developed nations (e.g., United States and New Zealand) and several culturally homogeneous regions, including New Europe, Latin America, the Middle East, and the Far and Southeast, support the prevalence of diverse consumptionscapes with multiple global consumer cultures, rather than a single global culture. Globalization and advances in technology have not created global norms and homogenized our identities, but behavioral patterns and regional identities that are surprisingly durable. Specifically, materialism was shown to influence perceived socioeconomic status both positively (for two regions) and negatively (for two regions), and relative life satisfaction (except in New Europe), while perceived socioeconomic status had a positive influence on relative life satisfaction (except in New Europe and Latin America). The quantity of television viewing was positively shown to influence materialism, directly in some cases, as well as through perceived realism in others, providing limited support for the cultivation theory effect. Finally, religiosity was shown to play a countervailing role in negatively influencing materialism only in Latin American and Middle Eastern countries, and a positive influence on relative life satisfaction only in Latin America. The rationale behind the differences across regions was also explored. The overall results can perhaps be best explained by “postmodern” epistemologies, in which people worldwide are increasingly implicated, and in which new traditions are constantly being invented.
