Does Political Affirmative Action Work, and for Whom? Theory and Evidence on India’s Scheduled Areas

Does political affirmative action undermine or promote development, and for whom? We examine Scheduled Areas in India, which reserve political office for the historically disadvantaged Scheduled Tribes. We apply a new theoretical framework and dataset of 217,000 villages to evaluate the overall impact of affirmative action on development, as well as its distributional consequences for minorities and non-minorities. Examining effects on the world’s largest employment program, the National Rural Employment Guarantee Scheme, we find that reservations deliver no worse overall outcomes, that there are large gains for targeted minorities, and that these gains come at the cost of the relatively privileged, not other minorities. We also find broader improvements in other pro-poor policies, including a rural roads program and general public goods. Contrary to the expectations of affirmative action skeptics, our results indicate that affirmative action can redistribute both political and economic power without hindering overall development

Performing folk punk : agonistic performances of intersectionality

The overarching goal of this project is to argue that folk punk performances offer spaces where a listening audience is exposed to a radical and intersectional politics, and enable that audience to identify with those views. By considering the performances of Inky Skulls, Pussy Riot!, and Against Me!, this study looks to the ways in which these folk punk exemplars highlight elements of the radical politics of the American left and in the history of folk and punk music. In particular, this project considers the intersections of race and class, women and nonhuman animals, and queerness and anarchism, as intersecting points of ideological convergence. The secondary goals of this project are two-fold. The first aim is to articulate a performative approach to folk punk music, as a scene worthy of academic consideration. The second aim is to consider the ways in which my personal experiences at folk punk shows highlight the idiosyncratic and utopian ways in which small performatives in the genre shape the identities of audience members and fans

Towards a general framework for an observation and knowledge based model of occupant behaviour in office buildings

This paper proposes a new general approach based on Bayesian networks to model the human behaviour. This approach represents human behaviour withprobabilistic cause-effect relations based not only on previous works, but also with conditional probabilities coming either from expert knowledge or deduced from observations. The approach has been used in the co-simulation of building physics and human behaviour in order to assess the CO 2 concentration in an office.Comment: IBPC 2015 Turin , Jun 2015, Turin, Italy. 201

Accuracy of Patient-Specific Organ Dose Estimates Obtained Using an Automated Image Segmentation Algorithm

The overall goal of this work is to develop a rapid, accurate, and automated software tool to estimate patient-specific organ doses from computed tomography (CT) scans using simulations to generate dose maps combined with automated segmentation algorithms. This work quantified the accuracy of organ dose estimates obtained by an automated segmentation algorithm. We hypothesized that the autosegmentation algorithm is sufficiently accurate to provide organ dose estimates, since small errors delineating organ boundaries will have minimal effect when computing mean organ dose. A leave-one-out validation study of the automated algorithm was performed with 20 head-neck CT scans expertly segmented into nine regions. Mean organ doses of the automatically and expertly segmented regions were computed from Monte Carlo-generated dose maps and compared. The automated segmentation algorithm estimated the mean organ dose to be within 10% of the expert segmentation for regions other than the spinal canal, with the median error for each organ region below 2%. In the spinal canal region, the median error was -7%, with a maximum absolute error of 28% for the single-atlas approach and 11% for the multiatlas approach. The results demonstrate that the automated segmentation algorithm can provide accurate organ dose estimates despite some segmentation errors

Auditory stimulus timing influences perceived duration of co-occurring visual stimuli

There is increasing interest in multisensory influences upon sensory-specific judgments, such as when auditory stimuli affect visual perception. Here we studied whether the duration of an auditory event can objectively affect the perceived duration of a co-occurring visual event. On each trial, participants were presented with a pair of successive flashes and had to judge whether the first or second was longer. Two beeps were presented with the flashes. The order of short and long stimuli could be the same across audition and vision (audio–visual congruent) or reversed, so that the longer flash was accompanied by the shorter beep and vice versa (audio–visual incongruent); or the two beeps could have the same duration as each other. Beeps and flashes could onset synchronously or asynchronously. In a further control experiment, the beep durations were much longer (tripled) than the flashes. Results showed that visual duration discrimination sensitivity (d′) was significantly higher for congruent (and significantly lower for incongruent) audio–visual synchronous combinations, relative to the visual-only presentation. This effect was abolished when auditory and visual stimuli were presented asynchronously, or when sound durations tripled those of flashes. We conclude that the temporal properties of co-occurring auditory stimuli influence the perceived duration of visual stimuli and that this can reflect genuine changes in visual sensitivity rather than mere response bias

Etudes de sensibilité avec COMETH

National audienceRESUME. La place importante des outils de calcul dans l'évaluation de la performance éner-gétique d'un bâtiment associé aux exigences toujours plus importantes sur les performances des bâtiments nécessite aujourd'hui de porter un regard critique sur leur abilité. Dans le cadre du projet ANR FIABILITE (HABISOL 2010), COMETH, (Coeur de calcul pour la Modélisation Énergétique et le confort Thermique) a été utilisé pour eectuer des études de sensibilité à di-vers paramètres. Cette démarche vise plusieurs objectifs. Tout d'abord, à valider notre capacité à fournir à la lière bâtiment des outils d'analyse de sensibilité rapide, simple d'utilisation et dont les résultats sont rapidement exploitables. Ensuite, sonder des paramètres jusqu'ici laissés de côté dans les approches thermiques horaires dynamiques dites "simples" (en référence au vocabulaire de la norme ISO 13790). MOTS-CLEFS.
