This book explores the concept of disability through a social, political, cultural, religious, and economics lens. It challenges the categorization of 'physically-disabled' produced by way of legal, medical, political, cultural, and literary narratives that comprise an exclusionary discourse.

AbstractThere is very little research on the topic of buy‐side analyst performance, and that which does exist yields mixed results. We use a large sample from both the buy‐side and the sell‐side and report several new results. First, while the contemporaneous returns to portfolios based on sell‐side recommendations are positive, the returns for buy‐side analysts, proxied by changes in institutional holdings, are negative. Second, the buy‐side analysts' underperformance is accentuated when they trade against sell‐side analysts' recommendations. Third, abnormal returns positively relate to both the portfolio size and the portfolio turnover of buy‐side analysts' institutions, suggesting that large institutions employ superior analysts and that superior analysts frequently change their recommendations. Abnormal returns are also positively related to buy‐side portfolios with stocks that have higher analyst coverage, greater institutional holding, and lower earnings forecast dispersion. Fourth, there is substantial persistence in buy‐side performance, but even the top decile performs poorly. These findings suggest that sell‐side analysts still outperform buy‐side analysts despite the severe conflicts of interest documented in the literature.

© 1963-2012 IEEE. Social persuasion to influence the actions, beliefs, and behaviors of individuals, embedded in a social network, has been widely studied. It has been applied to marketing, healthcare, sustainability, political campaigns, and public policy. Traditionally, there has been a separation between physical (offline) and cyber (online) worlds. While persuasion methods in the physical world focused on strong interpersonal trust and design principles, persuasion methods in the online world were rich on data-driven analysis and algorithms. Recent trends including Internet of Things, 'big data,' and smartphone adoption point to the blurring divide between the cyber world and the physical world in the following ways. Fine grained data about each individual's location, situation, social ties, and actions are collected and merged from different sources. The messages for persuasion can be transmitted through both worlds at suitable times and places. The impact of persuasion on each individual is measurable. Hence, we posit that the social persuasion will soon be able to span seamlessly across these worlds and will be able to employ computationally and empirically rigorous methods to understand and intervene in both cyber and physical worlds. Several early examples indicate that this will impact the fundamental facets of persuasion including who, how, where, and when, and pave way for multiple opportunities as well as research challenges.

AbstractIn this study, we revisit the link between R2 (synchronicity) and earnings management (opacity) because of the importance of the ongoing debate on the relation between idiosyncratic risk and earnings management in the finance and accounting literatures. Hutton et al. (J. Financial Economics, 2009) provide evidence of a positive link between opacity and R2. They interpret their finding to imply that firms with high R2 (high synchronicity) have less firm‐specific information impounded in their stock price. Our results for this relationship fail to unequivocally support the results reported in Hutton et al. (2009). We show that their results are not only time variant but also not robust to the alternative empirical technique recommended for panel data by Petersen (2009) and alternative estimation of discretionary accruals adjusted for firm performance prescribed by Kothari et al. (2005). We also find no support for a convex relation between idiosyncratic risk and opacity. The findings documented in this study substantially revise some of Hutton et al.'s findings in this important and growing area of research.
