“hard to type with one hand” : Att göra genus och sexualitet i lättklädda livestreams på Twitch.tv

Bruzelli, Caroline January 2024 (has links)
This study explores the (hetero)sexualized online space that is the category “Pools, Hot Tubsand Beaches” on the streaming platform Twitch.tv. The aim of the study is to gain a further understanding of how gender and sexuality is performed under the specific conditions offered by the space. Interactions between livestreamer and chat in three livestreams have been transcribed and analyzed using reflexive thematic analysis. I find that the space is characterized by the logic of the heterosexual matrix as defined by Judith Butler, as well by two foundational asymmetries that inform the way that gender and sexuality is performed in the spaces studied: the asymmetry of perspective and the asymmetry of performativity. These conditions are actively negotiated with by the subjects that interact in the space. Furthermore, relying on the work of Raewyn Connell, I find that the subjects conduct a labor of positionality with regards to notions of good and bad masculinity, basing their sense ofcommunity on the abjectification of “other men” in order to construct their own masculinity.

Swimming Pool on top of High-Rise Buildings : A comparison of different structural designs and positions of swimming pools

MUSINOVIC, ERVIN, CARLSSON, MATHIAS January 2021 (has links)
This thesis is about determining the risks of positioning swimming pools on top of high-rise buildings.Pursuing this determination, computational simulations of constructed structural models in a finiteelement model software called RFEM have been analyzed. In further pursuit of wanted results comingfrom the computational software, the models have acquired relevant theory regarding both swimmingpools and high-rise buildings respectively to obtain realistic approximations of equivalent results if themodels were real life structures. Thence analytical observations and measures of each structural modelcontaining different positions of the swimming pools are generated, in several degrees, differentpossibilities of risks of failure are possible. Results have been compared out of design of swimmingpools and high-rise buildings in an initial stage of background and thereafter set as input values for themodeling where following perspectives have been analyzed:• Structural deformations,• Internal forces,• Utilization ratios, and• Mode shapes.Further analysis of social-, economic-, and environmental sustainability have been deliberated. Thus,in conclusion of this thesis, swimming pools positioned on top of the structure core or at center of theplan section tend to harm the stability of the structure likewise if the positioning of the swimming poolare cantilevered completely over the edge of the rooftop. More suitable design would either bepositioning the swimming pool attached to the core of the structure meanwhile cantilevered over theedge or integrated entirely along the edge.The results showed that some of the overhanging swimming pools pass the requirements of theEurocode. This will result in the columns experiencing a utilization which exceed its capacity. Thecolumn utilization was shown to behave differently depending on where the swimming pool was placedon the top floor. Furthermore, it was also a difference between the structures studied as dimensions ofthe members required either more or less depending on the form the structure had. The reaction of theswimming pool could be observed to behave as a stiff part of the structures with the deformation mostlybeing located at the slabs. The internal forces developed in the members due to the swimming poolaffected the columns at the bottom floors the most. The thesis finally shows how much is needed forthe worst case of each structure to pass the requirements. This resulted in different dimensions for themembers where the smaller structure (structure model 1) needed bigger dimensions and the largerstructure (structure model 2) needed smaller dimensions compared to the originally based dimensions.The social, economic, and environmental impact of the structures showed that the larger structureswould release more carbon dioxide than the smaller structures. The social aspect was treated moreregarding the safety and the experience of the user of the facility of swimming pool. The reinforcementvaried the most between the structures with the concrete being mostly the same for the two differentstructures made, in which an impact was made for both the economic and the environmental. Here itwas shown that in order to pass the requirements of the Eurocodes the impact on the climate needed tobe considerable different.

Évaluation du potentiel de séquestration de carbone dans le sol de cultures intensives sur courtes rotations de saules dans le sud du Québec

Lockwell, Jérémie 08 1900 (has links)
Dans la dernière décennie, plusieurs hectares de terre agricole ont été convertis à la culture intensive sur courtes rotations (CICR) de saules dans le sud du Québec (Canada). Peu d’études ont été réalisées afin de déterminer comment se comporte la dynamique du carbone organique (Corg) dans le sol suivant cette conversion. Nous avons donc comparé la quantité du Corg et de deux pools labiles de carbone (carbone extractible à l’eau chaude et les sucres aminés) entre des CICR en phase initiale d’établissement (1-2 ans) et des parcelles appariées représentant le système de culture qui prévalait avant la transformation en culture de saules (culture fourragère) et d’autres cultures d’intérêt. La même chose a été faite pour une CICR en exploitation (depuis 9 ans) à un autre site. La quantité de Corg du sol n’était pas différente entre les CICR et les parcelles sous culture fourragère. Une plus haute concentration de sucres aminés dans le Corg total des CICR en établissement, par rapport aux autres parcelles sur le même site, permet de soupçonner que les perturbations liées à l’établissement ne mènent pas à une minéralisation accrue du Corg à court terme. La proportion de sucres aminés fongiques, qui diminue théoriquement lors de perturbations, était aussi plus élevée sous la plus jeune culture. Sous la CICR de neuf ans, le Corg était redistribué dans le profil vertical et les pools labiles étaient de plus petite taille (à une profondeur de 20-40 cm) comparativement à une parcelle témoin. La conversion d’une culture fourragère en plantation de saules en CICR n’a pas mené à la formation d’un puits de carbone. L’étude laisse entrevoir qu’un tel puits pourrait être créé si la conversion se faisait à partir d’un aménagement impliquant la culture en rotation de plantes annuelles et des labours. / Over the last ten years, many hectares of short-rotation willow coppice (SRWC) have been established on abandoned agricultural lands in southern Quebec (Canada). However, few studies were conducted to determine if these changes from a conventional crop to SRWC of willows would affect the soil carbon dynamic. A preliminary paired-site study was conducted to assess the impact of this land-use conversion on soil carbon stocks and dynamics shortly after they were established (1-year and 2-year) at one site and after multiple rotations (9-year) at another site. Apart from the total soil organic carbon pool, two labile carbon pools were investigated: the hot-water extractable carbon (HWC) pool and the amino sugars (AS) pool. Willow establishment and exploitation for nine years did not bring any changes in total organic carbon compared to an abandoned hay culture. The mature SRWC displayed a redistribution of TSOC in the vertical soil profile. We also measured a higher proportion of AS, compared to other plots on the same site, in total organic carbon under the 1-year-old SRWC; especially the proportion in AS of fungi origin that theorically decrease with perturbation intensity. Proportion of AS was also elevated under 2-year-old SRWC. A possible interpretation is that establishment-linked perturbations did not shift carbon dynamic toward an increased mineralization. The mature willow plantation exhibited depletion of HWC and the more labile amino sugar (muramic acid) in the deeper soil layer (20-40cm). This case study shows that conversion from an abandoned hay culture to a SRWC did not create a carbon sink. It was also found that the 9- year old willow plantation contained higher TSOC and had better soil quality than an adjacent short-term no-till crop rotation culture.

Aquatic phobias permeated through African American culture, economics, and politics

Unknown Date (has links)
This Project involves looking at African American culture as it relates to swimming, water safety awareness, and water skills. The paper explores the myths and cultural norms associated with drowning phobias in African Americans to discover the root causes. Through historic accounts of African American culture one begins to uncover reasons why this culture became, in a sense aqua phobic. The paper will show what water sport professionals are up against, when working with a culture that is several generations removed from the water and their water skills. The ultimate goal is to draw attention to the importance of water safety and the ability to swim as a life skill. / by Jon Eric Groover. / Vita. / Thesis (M.A.)--Florida Atlantic University, 2011. / Includes bibliography. / Electronic reproduction.

Competing for Talents : How a company can work with employer branding and talent management to attract talents

Benon, Hannah, Jansson, Charlotte January 2016 (has links)
This case study examines how a company can work with employer branding and talent management in order to attract students. The study explores how these concepts can be combined in the joint activity and what the implications are of arranging such an activity. This is illustrated through the case competition Brandstorm, arranged by L’Oréal Group. The study has a qualitative approach and it is based on in-depth interviews with managers on three different organizational levels at L’Oréal. The result shows that using a case competition as a joint activity is a tool to combine employer branding and talent management. The aim of a joint activity is two folded; the case is developed by the employer branding team to create awareness and appear as an attractive employer, further targeting students in order for the talent management team to spot and recruit talents. Additionally, the study highlights the importance of communicating a consistent Employer Value Proposition (EVP) that conveys symbolic values. A case competition can also be seen as a tool for managing talents and creating of talent pools. It is further clear that collaborating with universities is preferable when targeting students, thus conveying an attractive employer brand image.
