In this interview conducted shortly before his death in 2014, Stuart Hall, one of the seminal figures in cultural studies, talks about his classic work Policing the Crisis, describes the political, symbolic, and material concerns that animated cultural studies in the 1970s, and offers a critical assessment of the field today. He then turns his attention to the always shifting terrain of race and identity in the United States and Britain, offering fascinating cultural and political insights into the presidency of Barack Obama and the 2012 Olympics in London. While Hall was physically ill for much of his later life, this final interview provides powerful testimony that his formidable intellect, sense of humor, and willingness to engage with the gritty realities of politics and power never deserted him. An absolutely essential resource for anyone interested in cultural studies.

The quality control of MRI is essential for excluding problematic acquisitions and avoiding bias in subsequent image processing and analysis. Visual inspection is subjective and inapplicable in large scale datasets. Although automated quality assessments have been demonstrated on single-site datasets, those solutions do not generalize to unseen data acquired at new sites. Here, we evaluate the MRI Quality Control tool –MRIQC– in an experimental setup that addresses the generalization problem. MRIQC calculates a set of quality measures from each image and uses them as features in a binary (accept/exclude) classifier. The classifier is trained on a publicly available and multi-site dataset (17 sites, N=1102). We perform model selection and estimate an accuracy of 76%±13% on new sites using nested cross-validation, with a leave one-site-out split strategy. We confirm that result on a held-out dataset (2 sites, N=265) obtaining a 76% accuracy. We show how the classifier is blind to idiosyncratic artifacts and site effects as a result of over-fitting the training dataset. MRIQC performs with high accuracy in intra-site prediction, but improving the performance on new sites will require more labeled data and new approaches to overcome the between-site variability of the quality features. Breaking those limitations is crucial for a more objective quality assessment of neuroimaging, and to enable the analysis of extremely large and multi-site samples.

"The Penn Parsed Corpora of Historical English, including the Penn-Helsinki Parsed Corpus of Middle English, second edition (PPCME2), the Penn-Helsinki Parsed Corpus of Early Modern English (PPCEME), and the Penn Parsed Corpus of Modern British English, second edition (PPCMBE2), are running texts and text samples of British English prose across its history - from the earliest Middle English documents up to the First World War. The texts come in three forms: simple text, part-of-speech tagged text and syntactically annotated text. The syntactic annotation (parsing) permits searching not only for words and word sequences, but also for syntactic structure. All of the annotation has been carefully reviewed by expert human annotators for accuracy and consistency. The corpora are designed for the use of students and scholars of the history of English, especially the historical syntax of the language, and they are publicly available to individuals, research groups and libraries.." -- Penn Parsed Corpora of Historical English website.

Of all the activity observed on the Sun, two of the most energetic events are flares and Coronal Mass Ejections (CMEs). Usually, solar active regions that produce large flares will also produce a CME, but this is not always true (Yashiro et al., 2005). Despite advances in numerical modeling, it is still unclear which circumstances will produce a CME (Webb & Howard, 2012). Therefore, it is worthwhile to empirically determine which features distinguish flares associated with CMEs from flares that are not. At this time, no extensive study has used physically meaningful features of active regions to distinguish between these two populations. As such, we attempt to do so by using features derived from [1] photospheric vector magnetic field data taken by the Solar Dynamics Observatory's Helioseismic and Magnetic Imager instrument and [2] X-ray flux data from the Geostationary Operational Environmental Satellite's X-ray Flux instrument. We build a catalog of active regions that either produced both a flare and a CME (the positive class) or simply a flare (the negative class). We then use machine-learning algorithms to [1] determine which features distinguish these two populations, and [2] forecast whether an active region that produces an M- or X-class flare will also produce a CME. We compute the True Skill Statistic, a forecast verification metric, and find that it is a relatively high value of 0.8 plus or minus 0.2. We conclude that a combination of six parameters, which are all intensive in nature, will capture most of the relevant information contained in the photospheric magnetic field. The code and data used to do this analysis are included here.

Pride Denied tells the story of how corporate sponsors coopted the concept of LGBTQ pride, turning it into a feel-good brand and blunting its radical political edge. The film locates the origins of pride in sites of grassroots resistance and revolt, going back to the anti-police Stonewall uprising led by queer and trans people of color in 1969. It then traces how the deeply political roots of pride morphed into the depoliticized big-business PRIDE™ spectacles of today -- multimillion-dollar events designed to project an image of tolerance and equality rather than calling attention to the relationship between normative identity, power, and sexual repression. The film also offers a stunning case study in the politics of "pinkwashing, " detailing how the government of Israel has used its purported tolerance of gay rights to deflect attention away from its systematic repression of Palestinian human rights. Drawing on the insights of activists, artists, and educators, Pride Denied makes a compelling case for returning to the progressive political activism and grassroots community support that characterized the early LGBT rights movement.

Background: Two recent randomized trials produced discordant results when testing cardiovascular disease (CVD) benefits and harms of treating blood pressure (BP) to a low level. Objective: To perform a theoretical modeling study to identify whether large, clinically important differences in benefit and harm among patients (heterogeneous treatment effects, HTEs) can be hidden within, and explain discordance between, “treat-to-target” BP trials. Design: Microsimulation Data: Results of two trials comparing standard (treat to systolic BP <140mmHg) to intensive (<120 mmHg) BP treatment, and data from the National Health and Nutrition Examination Survey (2013-2014). Target population: U.S. adults Time Horizon: 5 years Interventions: BP treatment Outcome measures: CVD events and mortality Results of base-case analysis: Clinically important HTEs could explain differences in outcomes between two trials of intensive BP treatment, particularly diminishing benefit with each additional BP agent (e.g., adding a 2nd agent to 1 agent reduces CVD risk, hazard ratio = 0.61, but adding a 4th agent to a 3rd has no benefit), and increasing harm at low DBP. Results of sensitivity analysis: Conventional “treat-to-target” trial designs had poor (<5%) statistical power to detect the HTEs despite large samples (N>20,000), and produced biased effect estimates. By contrast, a trial with sequential randomization to more intensive treatment achieved >80% power and unbiased HTE estimates, with samples as low as N = 3,500. Limitations: We explored HTEs as a function of the number of BP medications only. Simulated aggregate data from the trials were used as model inputs, as individual participant data were not available. Conclusions: Clinically important heterogeneity in intensive BP treatment effects remains undetectable through conventional trial designs, but detectable through sequential randomization trial designs.
