The Relevance of Technology to Information Verification: Insights from Norwegian Journalism During a National Election

Growing concerns about disinformation have led to the development of new digital tools and systems designed for journalists’ verification and fact-checking needs. Despite these technological developments, research has demonstrated that emerging technologies are not utilised as often and are not as highly valued as industry narratives suggest. There are indications that the typical journalist values traditional skills such as writing and interviewing higher than digital technology skills and that many journalists do not consider the new tools to be very useful in their everyday work. This article takes on a sociotechnical approach to study the interplay between journalists, technology, organisational and professional routines. Specifically, we examine journalists’ use of verification technologies to detect disinformation during an election period. Our findings show a discrepancy between the alleged potential of new technologies and the everyday practices of newswork and fact-checking – also in the digitally advanced Norwegian media industry. We found tensions between established routines and cultures in the newsroom and the push for the renewal of journalistic methods which can be sorted under two headings: strategy vs. practice and proximity vs. distance to the beat and sources.The Relevance of Technology to Information Verification: Insights from Norwegian Journalism During a National ElectionpublishedVersio

The Role of Modifier Genes in Lynch Syndrome

There are a number of inherited predispositions to colorectal cancer (CRC) which can be broadly categorized into two groups; those with associated polyposis, such as familial adenomatous polyposis and the hamartomatous polyposis syndromes; and those that are linked to the non-polyposis syndromes, such as hereditary non polyposis colorectal cancer (HNPCC). The genetic basis of both the polyposis and non-polyposis syndromes are reflected in the CRC population who have no apparent family history of disease. Approximately 80% of all cases of CRC are associated with chromosomal instability [1] and are likely to have mutations in the Adenomatous Polyposis Coli (APC) gene whereas the remaining 20% with microsatellite instability appears to be due primarily to epigenetic inactivation of the DNA mismatch repair (MMR) gene MLH1 [2]

Is spending time in screen-based sedentary behaviors associated with less physical activity: a cross national investigation

<p>Abstract</p> <p>Background</p> <p>In Australia and the USA, national guidelines exist for limiting children's screen-exposure to two hours per day. This study aims to determine whether exceeding the suggested guidelines for screen-based sedentary behavior is associated with reduced levels of physical activity across different geographical regions.</p> <p>Methods</p> <p>Data material were taken from the 2005/2006 survey of "Health Behaviour in School-aged Children (HBSC) study; A WHO cross-National Survey". Data were collected through questionnaires from 11-,13- and,15- year olds. The final sample included 200,615 adolescents from 39 different countries in Europe and North America. Gender and country stratified analyses regressed time spent in leisure-time vigorous physical activity (VPA) and days of 60 minutes moderate to vigorous physical activity (MVPA) on time spent in screen-based sedentary behaviors. To simplify interpretation, the estimates from each country were pooled using a meta-analytic procedure.</p> <p>Results</p> <p>Exceeding 2 hrs of daily total screen-time was negatively associated with MVPA for both boys and girls, and with VPA for girls. When investigating the different types of screen-based behaviors separately, exceeding 2 hrs daily of TV viewing was associated with less MVPA for both boys and girls and less VPA for girls. Gaming was associated with less MVPA and VPA for boys, and non-gaming computer use was associated with higher levels of VPA for both genders. Stronger negative associations between physical activity and screen-based sedentary behaviors were found in countries where mean levels of physical activity were relatively high. The association between physical activity and sedentary behavior was not significantly associated with national levels of screen-based sedentary behaviors.</p> <p>Conclusions</p> <p>The displacement mechanism does not appear to be universal across countries. On a national level, negative associations between physical activity and screen-based sedentary behaviors are less likely to be found in countries with relatively low levels of physical activity. Consequently, national guidelines for limiting children and adolescents time in screen-based sedentary behavior may not be conducive to increasing levels of physical activity in all countries.</p

Design of monolithically integrated InGaAsP/InP passively-modelocked linear quantum well lasers in an active-passive integration scheme

In this paper simulation results of Fabry-Perot mode-locked lasers are presented that are based on measured modal gain data of InGaAsP quantum well optical amplifiers. Gain spectra were measured for various values of injected current density. The gain spectra were fitted to an analytical formula to describe the spectra using a few parameters. These were used as input parameters in a series of simulations of mode-locked lasers. The performance of three-section passively mode-locked lasers (amplifier, saturable absorber and passive waveguide) was studied for various lengths of the absorber and passive waveguide sections as well as various reflectivity values of the resonator mirrors
