Molecular gas and star formation in M81

We present IRAM 30m observations of the central 1.6 kpc of the spiral M81 galaxy. The molecular gas appears weak and with an unusual excitation physics. We discuss a possible link between low CO emission and weak FUV surface brightness.Comment: 2 pages, 2 figures, to appear in "Pathways through an eclectic Universe", J. H. Knapen, T. J.

Are truncated stellar disks linked to the molecular gas density?

We know that the slope of the radial, stellar light distribution in galaxies is well described by an exponential decline and this distribution is often truncated at a break radius ($R_{br}$). We don't have a clear understanding for the origin of these outer truncations and several hypotheses have been proposed to explain them. We want to test the various theories with direct observations of the cold molecular gas for a few truncated galaxies in comparison with the non-truncated ones. The answer to the existence of a possible link between truncated stellar disks and the molecular gas density cannot be obtained from CO maps in the literature, because so far there are no galaxies with a clear truncation observed in CO at high resolution.Comment: 3 pages, 6 figures, to appear in Astrophysics and Space Science (Apss), special issue of "Science with ALMA: a new era for Astrophysics" conference, ed.

HARKing and P-Hacking: A Call for More Transparent Reporting of Studies in the Information Systems Field

While researchers are expected to look for significant results to confirm their hypotheses, some engage in intentional or unintentional HARKing (Hypothesizing After Results are Known) and p-hacking (repeated tinkering with data and retesting). If these practices are widespread, one possible result is field-wide exaggerated (inflated) results reported in Information Systems (IS) publications. In this paper, we summarize the literature in HARKing and p-hacking across different disciplines. We offer an illustrative example of how an IS study could involve HARKing and p-hacking in various stages of the project to generate a more “publishable” result. We also report on a survey targeted at IS researchers to explore their experiences and awareness of this issue. Finally, we provide recommendations and suggestions based on the review of practices in other fields and advocate for more transparency in reporting research projects, so that study results can be interpreted properly, and reproducibility and replicability can be increased

Explaining the Engenderment and Role of Consumer Ambivalence in E-Commerce

Although trust and distrust are both crucial in online truster-trustee relationships, researchers disagree as to whether trust and distrust are distinct from each other. Given this debate, it is important to consider how distrust could be distinguished from trust. Accordingly, this paper extends the nomological network of distrust and introduces two novel antecedents never introduced in e-commerce literature: situational abnormalities and suspicion. We also propose that trust and distrust coexist in an online e-commerce relationship and can result in ambivalence when they both have high attitudinal values (represented in emotions, beliefs, or behaviours). Using a study of online consumer behaviour with 521 consumers, we largely validated our newly proposed model. We find that situational abnormalities and suspicion are separate, important novel antecedents to distrust. We also examine the effect of ambivalence on the truster’s intentions towards the website and find a small positive effect that increases the user’s intentions towards the website. Finally, we demonstrate the coexistence of trust and distrust as separate constructs, and highlight that distrust has a much larger impact on the truster’s intentions than trust. We conclude with implications to theory and practice, along with a discussion of the limitations and future opportunities

LISA: Mars and the limits of life

We describe the results of the first tests made on LISA, a simulator of planetary environments designed and built in Padua, dedicated to the study of the limit of bacterial life on the planet Mars. Tests on the cryogenic circuit, on the UV illumination and on bacterial coltures at room temperature that shall be used as references are described.Comment: 4 pages, 3 figures. Mem. SAIt, in pres

Galaxy evolution in nearby groups. II. Galaxy evolution in nearby loose groups. II. Photometric and kinematic characterization of USGC U268 and USGC U376 group members in the Leo cloud

We present the photometric and kinematic characterization of two groups, USGC U268 and USGC U376 located in different regions of the Leo cloud. U268, composed of 10 catalogued members and 11 new added members, has a small fraction (~24%) of early-type galaxies (ETGs). U376 has 16 plus 8 new added members, with ~38% of ETGs. We find the presence of significant substructures in both groups suggesting that they are likely accreting galaxies. U268 is located in a more loose environment than U376. For each member galaxy, broad band integrated and surface photometry have been obtained in far-UV and near-UV with GALEX, and in u,g, r, i, z (SDSS) bands. H_alpha imaging and 2D high resolution kinematical data have been obtained using PUMA Scanning Fabry-Perot interferometer at the 2.12 m telescope in San Pedro M\'artir, (Baja California, M\'exico). We improved the galaxy classification and we detected morphological and kinematical distortions that may be connected to either on-going and/or past interaction/accretion events or environmental induced secular evolution. U268 appears more active than U376, with a large fraction of galaxies showing interaction signatures (60% vs. 13%). The presence of bars among late-type galaxies is ~10% in U268 and ~$29% in U376. The cumulative distribution of (FUV - NUV) colours of galaxies in U268 is significantly different than that in U376 with galaxies in U268 bluer than those in U376. In the (FUV-r vs. M_r) and (NUV-r vs. M_r) planes no members of U268 are found in the `red sequence', even early-type galaxies lie in the `blue sequence' or in the `green valley'. Most (80%) of the early-type members in U376 inhabits the `red sequence, a large fraction of galaxies, of different morphological types, are located in the `green valley', while the `blue sequence' is under-populated with respect to U268.Comment: 27 pages, 11 figures, 8 tables, accepted for publication in MNRAS (abridged abstract

CORRELATION BETWEEN IBD, INTESTINAL DYSBIOSIS, DIET AND MOOD TONE DISEASE: ANALYSIS OF LITERATURE

This essay's main goal the present review is to highlight the connections between intestinal dysbiosis and the ensuing activation of the mucosal lymphatic system. One of the study's goals is to investigate the impact on mood caused by a serotonergic deficit driven by mucosal inflammation. It assesses the relationship between food consumption and the onset of psychological and mental illness as a secondary end aim. Patients with inflammatory bowel diseases and psychological and psychiatric mood disorders appear to benefit therapeutically from the sort of diet they consume

Operação Bororos: vivências de saúde, educação e cultura na Chapada dos Guimarães

Trabalho apresentado no II Congresso Nacional do PROJETO RONDON, realizado em Florianópolis, SC, no período de 23 a 25 de setembro de 2015 - Universidade Federal de Santa Catarina.Introdução: O Projeto Rondon é um programa interministerial, coordenado pelo Ministério da Defesa, que visa integrar e desenvolver ações comunitárias em regiões com maiores índices de pobreza e exclusão social, bem como áreas isoladas do território nacional necessitadas de maior aporte de bens e serviços. Em parceira com as universidades, o projeto pretende contribuir com a formação do universitário como cidadão, integrá-lo ao processo de desenvolvimento nacional por meio de ações participativas sobre a realidade do país. Além disso, visa consolidar no universitário o sentido de responsabilidade social coletiva, em prol da cidadania estimulando a produção de projetos coletivos locais, em parceria com as comunidades, com foco na capacitação de agentes multiplicadores, estimulando ações que valorizem o cidadão, a cultura local e promovam o intercâmbio de informações. Com esse espírito, a Instituição de Ensino Superior (IES) desenvolveu um plano de trabalho, aprovado para execução no município de Chapada dos Guimarães, estado do Mato Grosso, durante a Operação Bororos, no período de 10 a 26 de julho de 2015. Objetivo: Descrever as atividades realizadas no município, direcionadas aos profissionais de saúde, educação, assistência social e à comunidade em geral. Metodologia: A descrição se dará a partir do registro documental e fotográfico das atividades desenvolvidas e das avaliações feitas pelos participantes. Resultados: Foram realizadas 22 atividades de cultura, comunicação, saúde e educação, por meio de oficinas teórico-práticas, simpósios, mutirão de saúde e rodas de conversa, com participação de 293 pessoas. A maior parte das atividades foi concentrada na área urbana do município, em escolas, creches, centros culturais, praças e feiras ao ar livre. Observaram-se benefícios à comunidade com a troca de saberes e informações ofertadas pelos universitários, uma vez que agregaram novos subsídios para o trabalho cotidiano, seja dos multiplicadores ou dos cidadãos em geral que tiveram acesso às atividades desenvolvidas. Conclusão: O Projeto Rondon consolida-se como oportunidade única para os universitários colocarem em prática os conhecimentos adquiridos ao longo de suas vivências acadêmicas em prol da sociedade. Observou-se a necessidade de adequação das atividades priorizando-se as populações rurais caracterizadas como mais vulneráveis
