Green IT adoption via virtualization

Dissertação apresentada como requisito parcial para obtenção do grau de Mestre em Estatística e Gestão de Informação, especialização em Estudos de Mercado e Gestão de Relacionamento com o ClienteThis study attempts to test and validate the theoretical framework proposed by Bose and Luo (2011) that identifies and examines the factors that contribute to the assessment of a firm’s readiness to go green via IT-enable virtualization. The conceptual framework is based on three theoretical foundations: (1) technology-organization-environment (TOE) framework; (2) process virtualization theory (PVT); and (3) diffusion of innovation (DOI) theory. To test the framework, data were collected from 251 firms in Portugal and partial least square (PLS) was used to estimate the research model. The study found that environmental context (i.e., competition intensity and regulatory support) influences Green IT adoption more than the technological and organizational contexts. The research also confirmed that the pre-stage of adoption (i.e., Green IT initialization) influences the formal stage of adoption (i.e., Green IT integration), which in turn influences the post-adoption stage (i.e., Green IT maturation). As sustainable products and practices become increasingly relevant, the study adds new knowledge to this emergent area of IS research and provides valuable insights to IS managers and decision makers.Este estudo pretende testar e validar o modelo teórico proposto por Bose e Luo (2011), o qual identifica e analisa os factores que contribuem para a avaliação por parte das empresas da sua capacidade de adoptar tecnologias de informação sustentáveis (Green IT) através da virtualização. O modelo copceptual é baseado em três fundamentos teóricos: (1) contexto de inovação tecnológica (TOE framework), (2) teoria do processo de virtualização (PVT theory) e (3) difusão da inovação (DOI). Para testar o modelo, foram recolhidos dados de 251 empresas que operam em Portugal e posteriormente estimado o modelo através da metodologia de mínimos quadrados parciais (PLS). Através do estudo concluiu-se que contexto externo à empresa (ou seja, a intensidade da concorrência e o apoio regulatório) influencia mais a adopção de TI sustentáveis que os contextos tecnológico e organizacional. O estudo também confirmou que a fase de pré-adopção (i.e., inicialização de TI sustentáveis) influencia a fase formal de adopção (ou seja, a integração de TI sustentáveis), que por sua vez influencia a fase de pós-adopção (i.e., maturação de TI sustentáveis). Com os produtos e as práticas sustentáveis a tornarem-se cada vez mais relevantes, este estudo acrescenta novos conhecimentos a esta área emergente de Sistemas de Informação e fornece informações valiosas tanto para gestores de sistemas de informação como para decisores (e.g., politicos, empresariais, etc.)

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.
