Options and Accounting Information: Empirical Evidence in Stock and Derivative Markets
2014
This study investigates the informational role of options trading in the price discovery process around the dissemination of accounting information, specifically annual and quarterly earnings announcements. Firstly, we examine the effect of options markets by analyzing stock market reaction to earnings news conditional on the availability of options markets. Secondly, we examine options-trading activity around the release of earnings news. Results show that when options trading is available, the options market enhances the price efficiency of equity markets. Moreover, the dissemination of earnings news is associated with significant unusual activity in the options market due to informed tra…
Inducing efficient conditional cooperation patterns in public goods games, an experimental investigation
2010
This study analyses the behavior in a repeated public goods game when subjects know about the possibility of existence of strict conditional cooperators. We employed a baseline treatment and a threat treatment in which subjects are informed about the possibility of being in a group together with automata playing a grim trigger strategy. We conjecture the resulting game allows for almost fully efficient outcomes. Contributions in the threat treatment increase by 40% before a surprise restart, and by 50% after the surprise restart. In line with the grim trigger strategy subjects contribute either all or nothing in the threat treatment.
The informational role of thin options markets: Empirical evidence from the Spanish case
2016
This study investigates the informational role of thin options markets, specifically the Spanish options market. Firstly, we examine the effect of options markets by analysing stock market reaction to earnings news, conditional on the availability of options markets. Secondly, we examine options trading activity before the release of earnings news (including the announcement period). The results show that the impact on prices before the earnings release is significantly bigger when options trading is available. Moreover, the dissemination of earnings news is associated with significant unusual activity in the options market due to informed trading, especially when the earnings surprise is h…

A Data-Driven Approach to Dynamically Learn Focused Lexicons for Recognizing Emotions in Social Network Streams
2016
Opinion Mining aims at identifying and classifying subjective information in a collection of documents. A variety of approach exists in literature, ranging from Supervised Learning to Unsupervised Learning. Currently, one of the biggest opinion resource of opinionated texts existing on the Web is represented by Social Networks. Networks are not only a vast collection of documents but they also represent a dynamic evolving resource as the users keep posting their own opinions. We based our work relying on this idea of dynamicity, building an evolving model that updates itself in real time as users submit their posts. This is done through a set of supervised techniques based on a Lexi- con of…
Beyond MAYA for game-changing multisensory design
2017
With information technology becoming ever more embedded in our surrounding everyday things, the nature of interactions and the way we experience digitalization is becoming increasingly embodied. Thus, growing effort is placed on examining the multisensory nature of interaction experience. From a design perspective, increased knowledge of how people experience materials and how to design to encourage varying material experiences opens new opportunities for the generation of rich multisensory user experience, and accomplishing game-changing results. In particular, the innovation space opened up by understanding people's material expectations of designs is significant. An experiment (N = 78) w…
“This Racial Menace”?: Public Health, Venereal Disease and Maori in New Zealand, 1930–1947
2007
In 1939, Whakatane, on the remote east coast of the North Island of New Zealand, came to the attention of the New Zealand Department of Health as an area where syphilis was “suspected [to be] widespread”.1 This isolated part of the country was largely inhabited by Maori communities, and the revelation that venereal disease (VD) was so prevalent caught the Department by surprise, especially as a nationwide public health campaign against venereal disease had been in progress since 1917.2 In response, a comprehensive venereal disease campaign targeting Maori alone was developed––the earliest example of such a focus by the Department. This reaction highlighted what Dr Thomas Ritchie, Director o…
La penetración del modelo gramatical ‘general’ de tipo escolar en España
2008
Resumen En este artículo estudiamos la penetración, en el ámbito escolar español, de la gramática ‘general’ entre el final del siglo XVIII y el XIX (hasta 1845). Nuestro objetivo consistirá en mostrar que la difusión de este tipo de gramática en España, al igual que en Francia, está ligada no sólo a evoluciones internas, de tipo teórico, i.e. en relación con concepciones puramente lingüísticas, sino que se halla también determinada – y ello, de forma decisiva, aunque no sorprendente para los historiógrafos de la lingüística – por acontecimientos externos a la propia lingüística, como son los cambios en el marco escolar o en la legislación educativa. Mostraremos también que el inicio (en las…
Narratives of satisfying and unsatisfying experiences of current mobile augmented reality applications
2012
Over the last few years, mobile applications demonstrating Augmented Reality (AR) - such as Layar, Junaio and Google Goggles - have been introduced to consumers. We conducted an online survey to explore the user experience (UX) of early stage mobile AR applications available in the market in spring 2011, covering both location-based AR browsers and image recognition AR applications for object-based interaction. We identify various types of experiences such applications have evoked by qualitatively analyzing 84 users' narratives of their most satisfying and unsatisfying experiences. The results highlight, for example, experiences of awareness of surroundings, empowerment, positive surprise, …
Kościół dla wybranych? O specyfice indyjskich chrześcijan knānāya
2015
Nazwą knānāya (także „południowcy”) określa się jedno z ramion indyjskiego chrześcijaństwa, którego członkowie doszukują się swojej genezy w starożytnej emigracji perskich chrześcijan, przybyłych do Indii pod przewodnictwem kupca Tomasza z Kany. Charakterystyczną cechą tej grupy jest silne przywiązanie do tradycji i bezwarunkowa ochrona tożsamości łączącej współczesnych „południowców” z ich przodkami. Sam fakt głębokiego przywiązania do tradycji i w konsekwencji jej silna ochrona nie powinien dziwić, wszak jest to jedno z podstawowych praw każdej wspólnoty i każdego człowieka. Jednakże knanaici, chcąc zachować „czystość krwi”, zupełnie nie dopuszczają do siebie niczego i nikogo z zewnątrz. …
