A Comparative Study of American and French Fashion Conspicuous Consumption Habits on Instagram

As social media has become an integral part of every day communications, consumers have begun to conspicuously consume through the Internet. One social media platform, Instagram, puts a central focus on media sharing and allows its users to post photos and videos to their profiles. This makes Instagram an ideal place for Internet users to put their belongings on display. However, a user’s nationality and cultural upbringing could influence how one utilizes this platform to conspicuously consume. To determine if this were true, Instagram photos from American and French users were analyzed to find any potential discrepancies. Fashion items were the focus of the study. As photos were collected, it was noted if the user was American, French, or neither, if the user was male or female, and if a fashion item was present in the post. If present, it was decided if the item was being worn, if a fashion brand was tagged in the photo, if a brand name or logo was visible, if a brand related hashtag was used, if a fashion brand was mentioned in the photo caption, and if the aesthetic of the outfit was street style or more luxurious. It was revealed that both American and French Instagram users vary little from one another in terms of how they conspicuously consume using the platform. Despite major cultural differences, these two nationalities are shown to be more similar than not. Also, the two countries have very similar habits to that of other nations around the world. The results make it apparent that Americans and the French have similar habits, but are unable to determine the exact personal, social, or cultural motives behind how these Instagram users conspicuously consume. While these users may not differ in how they act, the reason behind the action may differ immensely. Further research should be completed to discover this information

AI is a viable alternative to high throughput screening: a 318-target study

: High throughput screening (HTS) is routinely used to identify bioactive small molecules. This requires physical compounds, which limits coverage of accessible chemical space. Computational approaches combined with vast on-demand chemical libraries can access far greater chemical space, provided that the predictive accuracy is sufficient to identify useful molecules. Through the largest and most diverse virtual HTS campaign reported to date, comprising 318 individual projects, we demonstrate that our AtomNet® convolutional neural network successfully finds novel hits across every major therapeutic area and protein class. We address historical limitations of computational screening by demonstrating success for target proteins without known binders, high-quality X-ray crystal structures, or manual cherry-picking of compounds. We show that the molecules selected by the AtomNet® model are novel drug-like scaffolds rather than minor modifications to known bioactive compounds. Our empirical results suggest that computational methods can substantially replace HTS as the first step of small-molecule drug discovery

Effectiveness of a national quality improvement programme to improve survival after emergency abdominal surgery (EPOCH): a stepped-wedge cluster-randomised trial

Background: Emergency abdominal surgery is associated with poor patient outcomes. We studied the effectiveness of a national quality improvement (QI) programme to implement a care pathway to improve survival for these patients. Methods: We did a stepped-wedge cluster-randomised trial of patients aged 40 years or older undergoing emergency open major abdominal surgery. Eligible UK National Health Service (NHS) hospitals (those that had an emergency general surgical service, a substantial volume of emergency abdominal surgery cases, and contributed data to the National Emergency Laparotomy Audit) were organised into 15 geographical clusters and commenced the QI programme in a random order, based on a computer-generated random sequence, over an 85-week period with one geographical cluster commencing the intervention every 5 weeks from the second to the 16th time period. Patients were masked to the study group, but it was not possible to mask hospital staff or investigators. The primary outcome measure was mortality within 90 days of surgery. Analyses were done on an intention-to-treat basis. This study is registered with the ISRCTN registry, number ISRCTN80682973. Findings: Treatment took place between March 3, 2014, and Oct 19, 2015. 22 754 patients were assessed for elegibility. Of 15 873 eligible patients from 93 NHS hospitals, primary outcome data were analysed for 8482 patients in the usual care group and 7374 in the QI group. Eight patients in the usual care group and nine patients in the QI group were not included in the analysis because of missing primary outcome data. The primary outcome of 90-day mortality occurred in 1210 (16%) patients in the QI group compared with 1393 (16%) patients in the usual care group (HR 1·11, 0·96–1·28). Interpretation: No survival benefit was observed from this QI programme to implement a care pathway for patients undergoing emergency abdominal surgery. Future QI programmes should ensure that teams have both the time and resources needed to improve patient care.

COUP-TFI Coordinates Cortical Patterning, Neurogenesis, and Laminar Fate and Modulates MAPK/ERK, AKT, and ß-Catenin Signaling

A major unsolved question in cortical development is how proliferation, neurogenesis, regional growth, regional identity, and laminar fate specification are coordinated. Here we provide evidence, using loss-of-function and gain-of-function manipulations, that the COUP-TFI orphan nuclear receptor promotes ventral cortical fate, promotes cell cycle exit and neural differentiation, regulates the balance of early- and late-born neurons, and regulates the balanced production of different types of layer V cortical projection neurons. We suggest that COUP-TFI controls these processes by repressing Mapk/Erk, Akt, and β-catenin signaling
