Measuring Organizational Legitimacy in Social Media: Assessing Citizens’ Judgments With Sentiment Analysis

Abstract: Conventional quantitative methods for the measurement of organizational legitimacy consider mainly three sources that make judgments about organizations visible: news media, accreditation bodies, and surveys Over the last decade, however, social media have enabled ordinary citizens to bypass the gatekeeping function of these institutional evaluators and autonomously make individual judgments public This inclusion of voices beyond functional and formally organized stakeholder groups potentially pluralizes the ongoing discussions about organizations The individual judgments in blogs, tweets, and Facebook posts give indication about the broader fit between an organization’s perceived behavior and heterogeneous social norms and therefore constitute an indicator of organizational legitimacy that can be accessed and measured We propose the use of social media data and sentiment analysis to study the affect-based responses to organizational actions by citizens We critically discuss and compare the method wi

Volatility Risk Premia and Exchange Rate Predictability

Abstract: We discover a new currency strategy with highly desirable return and diversification properties, which uses the predictive capability of currency volatility risk premia for currency returns. The volatility risk premium -- the difference between expected realized volatility and model-free implied volatility -- reflects the costs of insuring against currency volatility fluctuations, and the strategy sells high-insurance-cost currencies and buys low-insurance-cost currencies. The returns to the strategy are mainly generated by movements in spot exchange rates rather than interest rate differentials, and the strategy carries a large weight in a minimum-variance portfolio of commonly employed currency strategies. We explore alternative explanations for the profitability of the strategy, which cannot be understood using traditional risk factors.

Memory and the self in autism: A review and theoretical framework

Abstract: This article reviews research on (a) autobiographical episodic and semantic memory, (b) the self-reference effect, (c) memory for the actions of self versus other (the self-enactment effect), and (d) non-autobiographical episodic memory in autism spectrum disorder (ASD), and provides a theoretical framework to account for the bidirectional relationship between memory and the self in ASD. It is argued that individuals with ASD have diminished psychological self-knowledge (as a consequence of diagnostic social and communication impairments), alongside intact physical self-knowledge, resulting in an under-elaborated self-concept. Consequently, individuals with ASD show impaired autobiographical episodic memory and a reduced self-reference effect (which may each rely on psychological aspects of the self-concept) but do not show specific impairments in memory for their own rather than others’ actions (which may rely on physical aspects of the self-concept). However, it is also argued that memory impairments in...
