O papel de motivações utilitárias e hedônicas na cocriação de valor e sua relação com a experiência no AIRBNB

The article investigates the role of utilitarian and hedonic motivations in value co-creation and their relationship to consumption experience in a hosting service offered by a collaborative platform: AirBnb. Based on the literature on shared economy and collaborative consumption, hypotheses were formulated and a conceptual model proposed. A survey of 967 respondents was conducted and data analyzed using structural equation modeling technique. Results show that utilitarian motivations are not related to value co-creation and consumption experience, unlike hedonic ones that showed a positive association with both variables. Furthermore, findings show that value co-creation plays role as antecedent of consumption experience as a mediator variable in the relationship between hedonic motivations and consumption experience. This research brings important contributions to the area, since it empirically evidenciates that hedonic motivations are presente in collaborative consumption practices, more specifically in shared hosting services. In addition, it consubstanciates previous studies that recognize value co-creation as an important aspect in offering positive experiences in hospitality and tourism services.El artículo investiga el papel de las motivaciones utilitarias y hedónicas en la creación conjunta de valor y su relación con la experiencia de consumo en un servicio de alojamiento ofrecido por una plataforma colaborativa: AirBnb. Con base en la literatura sobre economía compartida y consumo colaborativo, se formularon hipótesis y se propuso un modelo conceptual. Se realizó una encuesta a 967 encuestados y se analizaron los datos utilizando la técnica de modelado de ecuaciones estructurales. Los resultados muestran que las motivaciones utilitarias no están relacionadas con la co-creación de valor y la experiencia de consumo, a diferencia de las hedónicas que mostraron una asociación positiva con ambas variables. Además, los resultados muestran que la creación conjunta de valores desempeña un papel como antecedente de la experiencia de consumo como una variable mediadora en la relación entre las motivaciones hedónicas y la experiencia de consumo. Esta investigación aporta importantes contribuciones al área, ya que evidencia empíricamente que las motivaciones hedónicas están presentes en las prácticas de consumo colaborativo, más específicamente en los servicios de alojamiento compartido. Además, constituye estudios previos que reconocen la creación conjunta de valor como un aspecto importante para ofrecer experiencias positivas en servicios de hospitalidad y turismo.O artigo investiga o papel de motivações utilitárias e hedônicas na cocriação de valor e sua relação com a experiência de consumo em serviços de hospedagem oferecido por plataforma de consumo colaborativo: o AirBnb.

Esta pesquisa traz contribuições importantes para a área, uma vez traz evidência empírica do papel que motivações hedônicas exerce em práticas de consumo colaborativo, mais especificamente em serviços de hospedagem compartilhada.

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora

Precision measurement of the structure of the CMS inner tracking system using nuclear interactions

The structure of the CMS inner tracking system has been studied using nuclear interactions of hadrons striking its material. Data from proton-proton collisions at a center-of-mass energy of 13 TeV recorded in 2015 at the LHC are used to reconstruct millions of secondary vertices from these nuclear interactions. Precise positions of the beam pipe and the inner tracking system elements, such as the pixel detector support tube, and barrel pixel detector inner shield and support rails, are determined using these vertices. These measurements are important for detector simulations, detector upgrades, and to identify any changes in the positions of inactive elements
