Organisational structure, communication and group ethics

This paper investigates experimentally how organisational decision processes affect the moral motivations of actors inside a firm that must forego profits to reduce harming a third party. In a "vertical" treatment, one insider unilaterally sets the harm-reduction strategy; the other can only accept or quit. In a "horizontal" treatment, the insiders decide by consensus. Our 2-by-2 design also controls for communication effects. In our data, communication makes vertical firms more ethical; voice appears to mitigate "responsibility-alleviation" in that subordinates with voice feel responsible for what their firms do. Vertical firms are then more ethical than the horizontal firms for which our bargaining data reveal a dynamic form of responsibility-alleviation and our chat data indicate a strong "insider-outsider" effect.

Application of discriminant function analysis and change-point problem in dating volcanic ashes

The application of Discriminant function analysis (DFA) is not a new idea in the studyof tephrochrology. In this paper, DFA is applied to compositional datasets of twodifferent types of tephras from Mountain Ruapehu in New Zealand and MountainRainier in USA. The canonical variables from the analysis are further investigated witha statistical methodology of change-point problems in order to gain a betterunderstanding of the change in compositional pattern over time. Finally, a special caseof segmented regression has been proposed to model both the time of change and thechange in pattern. This model can be used to estimate the age for the unknown tephrasusing Bayesian statistical calibration

Pre-play communication and credibility: A test of Aumann's conjecture

The effectiveness of pre-play communication in achieving efficientoutcomes has long been a subject of controversy. In some environments,cheap talk may help to achieve coordination. However, Aumannconjectures that, in a variant of the Stag Hunt game, a signal forefficient play is not self-enforcing and concludes that an "agreementto play [the efficient outcome] conveys no information about what theplayers will do." Harsanyi and Selten (1988) cite this example as anillustration of risk-dominance vs. payoff-dominance. Farrell and Rabin(1996) agree with the logic, but suspect that cheap talk willnonetheless achieve efficiency. The conjecture is tested with one-waycommunication. When the sender first chooses a signal and then anaction, there is impressive coordination: a 94% probability for thepotentially efficient (but risky) play, given a signal for efficientplay. Without communication, efforts to achieve efficiency wereunsuccessful, as the proportion of B moves is only 35%. I also test ahypothesis that the order of the action and the signal affects theresults, finding that the decision order is indeed important. WhileAumann s conjecture is behaviorally disconfirmed when the signal isdetermined initially, the signal s credibility seems to be much moresuspect when the sender is known to have first chosen an action, andthe results are not statistically distinguishable from those whenthere is no signal. Some applications and issues in communication andcoordination are discussed.

Strategy communication and measurement systems

Organizations often face the challenge of communicating their strategiesto local decision makers. The difficulty presents itself in finding away to measure performance wich meaningfully conveys how to implement theorganization's strategy at local levels. I show that organizations solvethis communication problem by combining performance measures in such away that performance gains come closest to mimicking value-added asdefined by the organization's strategy. I further show how organizationsrebalance performance measures in response to changes in their strategies.Applications to the design of performance metrics, gaming, and divisionalperformance evaluation are considered. The paper also suggests severalempirical ways to evaluate the practical importance of the communicationrole of measurement systems.

Electronic journals, scholarly communication and libraries

The recent surge in scientific electronic journals began when libraries began having access to the WWW in the mid-1990s. The shift from paper to digital has affected the traditional alignment and role of the primary "stakeholders" -mainly authors, publishers, universities and libraries. The author offers a brief review of the history of the scholarly journal followed by the evolution of e-journals in during the past two decades. The article then focuses on the implications that these have had on traditional library processes and services such as selection, acquisitions, cataloguing, storage, preservation and user services. In the conclusion the author speculates on the long term effect of Web-based publishing on the format of the traditional scholarly journal as it has existed for over 300 years.

Processes and consequences in business ethical dilemmas: The oil industry and climate changes

This paper proposes a framework to examine business ethical dilemmas andbusiness attitudes towards such dilemmas. Business ethical dilemmas canbe understood as reflecting a contradiction between a socially detrimentalprocess and a self-interested profitable consequence. This representationallows us to distinguish two forms of behavior differing by whetherpriority is put on consequences or on processes. We argue that theseforms imply very different business attitudes towards society:controversial or competitive for the former and aligned or cooperativefor the latter. These attitudes are then analyzed at the discursive level in order to address the question of good faith in businessargumentation, i.e. to which extent are these attitudes consistent withactual business behaviors. We argue that consequential attitudes mostlyinvolve communication and lobbying actions aiming at eluding the dilemma.Therefore, the question of good faith for consequential attitudes liesin the consistency between beliefs and discourse. On the other hand,procedural attitudes acknowledge the dilemma and claim a change of theprocess of behavior. They thus raise the question of the consistencybetween discourses and actual behavior. We apply this processes/consequencesframework to the case of the oil industry s climate change ethical dilemmawhich comes forth as a dilemma between emitting greenhouse gases and making more profits . And we examine the different attitudes of two oilcorporations-BP Amoco and ExxonMobil-towards the dilemma.

Numerical simulation of combined heat transfer phenomena (conduction, convection, and radiation). Application to he optimisation of thermal systems

Thermal systems interchanging heat and mass by conduction, convection, radiation (solar and thermal ) occur in many engineering applications like energy storage by solar collectors, window glazing in buildings, refrigeration of plastic moulds, air handling units etc. Often these thermal systems are composed of various elements for example a building with wall, windows, rooms, etc. It would be of particular interest to have a modular thermal system which is formed by connecting different modules for the elements, flexibility to use and change models for individual elements, add or remove elements without changing the entire code. A numerical approach to handle the heat transfer and fluid flow in such systems helps in saving the full scale experiment time, cost and also aids optimisation of parameters of the system. In subsequent sections are presented a short summary of the work done until now on the orientation of the thesis in the field of numerical methods for heat transfer and fluid flow applications, the work in process and the future work.

Comparing Governmental Agendas: Evolution of the Prioritization of Issues in the USA and Spain

This paper is the first step in a long term project investigating policy stability and change in Spain from an agenda setting perspective and comparing the Spanish policy agenda to that of other advanced democracies. Here we begin to compare the allocation of issue attention in Spain and the USA by comparing the substance of annual President and Prime Minister speeches from 1982 to 2005. Existing research argues that the public agenda has become more crowded, competitive and volatile in recent years. We find that in both countries there has been a transformation of the political agenda towards an increasing diversity of issues. However, most of the volatility in executive attention seems to be explained by salient events rather than by issue crowding. We conclude by discussing some limitations of executive speeches as a measure of governmental issue attention and directions for future research.

Análisis de las de las funcionalidades 2.0 ofrecidas por los repositorios españoles

Els Repositoris Institucionals suposen un element nou en l'entorn universitari pel que fa a la comunicació científica i a la presència digital de la producció de les universitats. Però l'entorn digital evoluciona molt ràpidament, així com els diferents agents implicats en la publicació científica. El canvi més important en la comunicació web que s'ha donat en els últims anys ha estat l'aparició dels serveis englobats sota l'etiqueta Web 2.0 en què s'inclouen diferents serveis per compartir enllaços, objectes digitals, gestionar relacions socials, reutilitzar informació, etc. Algunes publicacions científiques ja estan oferint aquest tipus de serveis. El present treball analitza el grau d'implantació d'aquest tipus de serveis en l'àmbit dels dipòsits institucionals espanyols. Per això en primer lloc s'identifiquen els tipus de serveis considerats 2.0 i que poden ser d'utilitat per a la comunicació científica. En segon lloc es comptabilitza quines d'aquestes possibilitats son ofertes pels repositoris i per últim s'analitzen els resultats per a comprovar les accions realitzades i identificar les possibles línies de millora.

Developing and evaluating a pictogram-based Instant Messaging service for individuals with cognitive disabilities

Information and communication technologies pose accessibility problems to people with disabilities because its design fails to take into account their communication and usability requirements. The impossibility to access the services provided by these technologies creates a situation of exclusion that reduces the self-suficiency of disabled individuals and causes social isolation, which in turn diminishes their overall quality of life. Considering the importance of these technologies and services in our society, we have developed a pictogram-based Instant Messaging service for individuals with cognitive disabilities who have reading and writing problems. Along the paper we introduce and discuss the User Centred Design methodology that we have used to develop and evaluate the pictogram-based Instant Messaging service and client with individuals with cognitive disabilities taking into account their communication and usability requirements. From the results obtained in the evaluation process we can state that individuals with cognitive disabilities have been able to use the pictogram-based Instant Messaging service and client to communicate with their relatives and acquaintances, thus serving as a tool to help reducing their social and digital exclusion situation.

Economic rationality and ethical behavior

This paper argues that economic rationality and ethical behavior cannotbe reduced one to the other, casting doubts on the validity of formulaslike 'profit is ethical' or 'ethics pays'. In order to express ethicaldilemmas as opposing economic interest with ethical concerns, we proposea model of rational behavior that combines these two irreducible dimensions in an open but not arbitrary manner. Behaviors that are neither ethicalnor profitable are considered irrational (non-arbitrariness). However,behaviors that are profitable but unethical, and behaviors that are ethicalbut not profitable, are all treated as rational (openness). Combiningethical concerns with economic interest, ethical business is in turn anoptimal form of rationality between venality and sacrifice.Because every one prefers to communicate that he acts ethically, ethicalbusiness remains ambiguous until some economic interest is actuallysacrificed. We argue however that ethical business has an interest indemonstrating its consistency between communication and behavior by atransparent attitude. On the other hand, venal behaviors must remainconfidential to hide the corresponding lack of consistency. Thisdiscursive approach based on transparency and confidentiality helpsto further distinguish between ethical and unethical business behaviors.

Redes digitales de comunicación, participación ciudadana y periodismo online durante la primavera árabe: Túnez, 17 de diciembre de 2010-23 de octubre de 2011.

El presente proyecto de investigación se presenta como trabajo final del Máster en Estudis Avançats en Comunicació Social y pretende sentar las bases de la futura tesis doctoral. Se plantea una investigación que tiene como objetivo determinar la capacidad que tuvo el uso de las redes digitales de comunicación para modificar la esfera pública durante la primavera árabe en Túnez y el posterior proceso de Transición llevado a cabo. Para ello la investigación se aborda desde tres conceptos clave: el pluralismo mediático, la relevancia mediàtica y los procesos comunicativos. La investigación se abordará triangulando los métodos cuantitativo y cualitativo y se propone como técnica el anàlisis de contenido sobre la nueva legislación tunecina en materia de Políticas de Comunicación, así como del contenido generado por los usuarios en las redes digitales de comunicación y las noticias de medios de referencia online árabes (3) y occidentales (4) en relación con el objeto de estudio.

Disseny d’un sistema d’entrenament per l’escalada

El projecte proposa un sistema d’entrenament per l’escalada, donant noves solucions adaptades a les noves tendències socials i de mercat. La millora en la comunicació usuari-producte i el seguiment del progrés en l’entrenament són les bases d’aquest projecte, entorn a les quals giren totes les solucions plantejades. Donat l’increment exponencial dels usuaris de sales d’entrenament i aficionats a l’escalada en els últims deu anys, on m’incloc, aquest projecte pretén donar una nova visió més real de l’entrenament, plantejant un producte versàtil i canviant, el qual s’adequa a les necessitats concretes de cada usuari, a l’hora que proposa diferents muntatges segons les possibilitats de l’espai d’instal·lació. L’interès personal per l’escalada i l’experiència durants els últims anys en sales d’entrenament m’han fet plantejar-me la funció de diferents elements dins d’aquests espais. L’ús de noves tecnologies i de sistemes de programació específics donen a l’usuari l’oportunitat d’endinsar-se en tota una experiència diferent d’entrenament, on pot dissenyar el seu propi pla, tenir un seguiment estadístic de la seva evolució i ser partícip d’una xarxa social de contactes, recomanacions, actualitzacions d’exercicis i plantejament de nous reptes. Naixent les sales d’entrenament a la dècada dels seixanta, avui dia són més de 40 les empreses dedicades a la producció i fabricació de material per elles. Només un 11% inverteixen en innovació i disseny i, tot i així, els resultats, en la majoria dels casos, no es desmarquen gaire d’allò que ja existeix. Amb aquest projecte es vol obrir un nou paradigma en el sector, donar la volta a allò existent i mostrar que fent un bon estudi de necessitats es poden plantejar solucions molt més reals, adaptables i personalitzables.
