    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Energy Transition: Semi-Automatic BIM Tool Approach for Elevating Sustainability in the Maputo Natural History Museum

    Mozambique is experiencing the consequences of a severe energy crisis with economic and social impacts. Its strict dependence on hydroelectric sources is being severely tested by recent droughts that have drastically reduced water levels in dams. However, Mozambique is addressing energy poverty by exploring renewable energy sources thanks to investments in the sector by the European Union. The research concerns an energy analysis profile of the country and the penetration of renewable energy, presenting an energy upgrading scope through a semi-automatic calculation methodology in a Building Information Modeling (BIM) environment. The building under study, located in Maputo, is the Natural History Museum, which plays an important role in biodiversity conservation. Therefore, this paper proposes a BIM methodology for sizing an environmental control system tailored to serve the museum. The proposed system replaces the previous one and includes a photovoltaic system that not only meets the museum’s load but also supplies electricity to the surrounding area. Energy production from renewable sources with a surplus of 30% has been achieved. The proposed digital methodology has identified a maximum gap of 1.5% between the dimensions of the BIM duct and those of a traditional plant design, meeting ASHRAE requirements for environmental control

    Degree-doubling graph families

    Let G be a family of n-vertex graphs of uniform degree 2 with the property that the union of any two member graphs has maximum degree 4. We determine the leading term in the asymptotics of the largest cardinality of such a family. Several analogous problems are discussed. ©2013 Society for Industrial and Applied Mathematics

    Social media misuse explained by emotion dysregulation and self-concept: an ecological momentary assessment approach

    No full text
    Studies suggested that emotion dysregulation and identity processes are involved in social media (SM) misuse, even if their proximal role has not been investigated. Previous studies rarely discriminated between specific activities or between types of SM. We recruited 50 young adults and implemented a momentary ecological assessment measurement. Four times by day, during seven days, we measured SM use, frequency of several activities on SM, emotion dysregulation, distress and clarity of self-concept. Daily time spent on Facebook, Instagram and TikTok were retrieved from devices. Intradaily changes in emotion dysregulation and clarity of self-concept predict changes in SM addiction symptoms and frequency of use according to the type of activity. Daily changes in time spent on SM were not predicted by emotion dysregulation, distress and self-concept clarity. Findings suggest that emotion dysregulation and poor self-concept clarity are proximal risk factors for SM misuse
