"Jag lever liksom mitt jobb" - En studie om hur hypermobilitet har påverkat den samtida affärsresenärens livsstil samt statuskommunicerande

Mobility is becoming an even bigger part of people's lives in our global society. People travel more than ever and the forecast says it will not slow down. Business traveling has become a big part of this mobility, and especially aeromobility, therefore it is a topic worth further investigation. This study focuses on the relation between hypermobile business travelers' behavior and how their identity is shaped and communicated. The study discusses the questions of how hypermobile behavior has become a part of the business travelers' lifestyle and how business travelers communicate their status through social media before, during and after their travels. The study is conducted through two qualitative research methods; semi structured interviews and a document analysis. The sample comprises of nine business travelers that travel more than twice a month within their work and on their spare time. The study shows how hypermobility has become a lifestyle for the travelers, even though they admit it or not. It has affected how they see themselves but also how they see other travelers and what group they want to be associated with or not be associated with. The study also shows that the communication of status and hypermobility do not really exist since the respondents do not want to be associated with bragging. If our respondents' social media communication are to increase, it must be because of some extraordinary happening since traveling is something connected to the ordinary for these travelers

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

Megastudy testing 25 treatments to reduce anti-democratic attitudes and partisan animosity

Scholars warn that partisan divisions in the mass public threaten the health of American democracy. We conducted a megastudy (n=32,059 participants) testing 25 treatments designed by academics and practitioners to reduce Americans’ partisan animosity and anti-democratic attitudes. We find many treatments reduced partisan animosity, most strongly by highlighting relatable sympathetic individuals with different political beliefs, or by emphasizing common identities shared by rival partisans. We also identify several treatments that reduced support for undemocratic practices – most strongly by correcting misperceptions of rival partisans’ views, or highlighting the threat of democratic collapse – showing anti-democratic attitudes are not intractable. Taken together, the study’s findings identify promising general strategies for reducing partisan division and improving democratic attitudes, shedding new theoretical light on challenges facing American democracy
