Online News Media Impact on Disaster Response: October 26, 2010 Indonesian Disaster Case Study

This paper reflects a research project on the influence of online news media (from print, radio, and televised outlets) on disaster response. Coverage on the October 2010 Indonesian tsunami and earthquake was gathered from 17 sources from October 26 through November 30. This data was analyzed quantitatively with respect to coverage intensity over time and among outlets. Qualitative analyses were also conducted using keywords and value scale that assessed the degree of positivity or negativity associated with that keyword in the context of accountability. Results yielded insights into the influence of online media on actors' assumption of accountability and quality of response. It also provided information as to the optimal time window in which advocates and disaster management specialists can best present recommendations to improve policy and raise awareness. Coverage of outlets was analyzed individually, in groups, and as a whole, in order to discern behavior patterns for a better understanding of media interdependency. This project produced analytical insights but is primarily intended as a prototype for more refined and extensive research.

How do Australian print media representations of child abuse and neglect inform the public and system reform?

The print media play a vital role in informing the public about child abuse and neglect. This information helps build broad support for laws and system developments that enable the state to intervene into private family lives and ensure that children are protected from maltreatment. Print media coverage usually sets the daily media agenda. It therefore influences public understandings of child abuse and neglect and what people believe should be done about it. Media impact on policy agendas should not be underestimated. This article outlines the results of a study of all major Australian newspaper stories covering abuse and neglect matters during an 18-month period in 2008–2009. A range of issues are identified concerning how well these stories inform the public about the nature of the problem and the current national reform agenda for protective systems that promotes early intervention and prevention...

Media Coverage and Charitable Giving After the 2004 Tsunami

Media coverage of humanitarian crises is widely believed to influence charitable giving, yet this assertion has received little empirical scrutiny. Using Internet donations after the 2004 tsunami as a case study in a tobit framework, we show that media coverage of disasters increases charitable donations, with an additional minute of nightly news coverage increasing donations by 0.036 standard deviations from the mean. We repeat the analysis using instrumental variables in a tobit model to account for endogeneity, and the estimates are unchanged. We also show that the magnitude and sign of media impact vary by news source and relief agency.

Enlisting the influence of others: Alternative strategies for persuasive media campaigns

This study investigated an Australian antidrug campaign that targeted adolescents directly and indirectly via recruiting parents into drug prevention. Eighty-six parent-child dyads completed surveys measuring campaign evaluations, discussions about drugs, and beliefs about risks to self (own child) and to the average young Australian. Adolescents were optimistic about risks, and media impact was evident only in perceptions of risk to others. Parents were less optimistic, and perceptions of campaign quality predicted perceived risk to own child and discussion about drugs. However, this was moderated by negative affect associated with the campaign. There was some evidence that discussions influenced adolescents' perceptions of personal risk. This demonstrates the importance of individual responses and communication processes in determining the impact of persuasive media messages.

Fishing effort control regulations influence on stability, safety and operability of small fishing vessels: study of a series of stability related accidents occurred in Spain between 2004 and 2007

Entre los años 2004 y 2007 se hundieron por problemas de estabilidad cinco pesqueros españoles de pequeña eslora, de características parecidas, de relativamente poca edad, que habían sido construidos en un intervalo de pocos años. La mayoría de los tripulantes de esos pesqueros fallecieron o desaparecieron en esos accidentes. Este conjunto de accidentes tuvo bastante repercusión social y mediática. Entre ingenieros navales y marinos del sector de la pesca se relacionó estos accidentes con los condicionantes a los diseños de los pesqueros impuestos por la normativa de control de esfuerzo pesquero. Los accidentes fueron investigados y publicados sus correspondientes informes; en ellos no se exploró esta supuesta relación. Esta tesis pretende investigar la relación entre esos accidentes y los cambios de la normativa de esfuerzo pesquero. En la introducción se expone la normativa de control de esfuerzo pesquero analizada, se presentan datos sobre la estructura de la flota pesquera en España y su accidentalidad, y se detallan los criterios de estabilidad manejados durante el trabajo, explicando su relación con la seguridad de los pesqueros. Seguidamente se realiza un análisis estadístico de la siniestralidad en el sector de la pesca para establecer si el conjunto de accidentes estudiados supone una anomalía, o si por el contrario el conjunto de estos accidentes no es relevante desde el punto de vista estadístico. Se analiza la siniestralidad a partir de diversas bases de datos de buques pesqueros en España y se concluye que el conjunto de accidentes estudiados supone una anomalía estadística, ya que la probabilidad de ocurrencia de los cinco sucesos es muy baja considerando la frecuencia estimada de pérdidas de buques por estabilidad en el subsector de la flota pesquera en el que se encuadran los cinco buques perdidos. A continuación el trabajo se centra en la comparación de los buques accidentados con los buques pesqueros dados de baja para construir aquellos, según exige la normativa de control de esfuerzo pesquero; a estos últimos buques nos referiremos como “predecesores” de los buques accidentados. Se comparan las dimensiones principales de cada buque y de su predecesor, resultando que los buques accidentados comparten características de diseño comunes que son sensiblemente diferentes en los buques predecesores, y enlazando dichas características de diseño con los requisitos de la nueva normativa de control del esfuerzo pesquero bajo la que se construyeron estos barcos. Ello permite establecer una relación entre los accidentes y el mencionado cambio normativo. A continuación se compara el margen con que se cumplían los criterios reglamentarios de estabilidad entre los buques accidentados y los predecesores, encontrándose que en cuatro de los cinco casos los predecesores cumplían los criterios de estabilidad con mayor holgura que los buques accidentados. Los resultados obtenidos en este punto permiten establecer una relación entre el cambio de normativa de esfuerzo pesquero y la estabilidad de los buques. Los cinco buques accidentados cumplían con los criterios reglamentarios de estabilidad en vigor, lo que cuestiona la relación entre esos criterios y la seguridad. Por ello se extiende la comparativa entre pesqueros a dos nuevos campos relacionados con la estabilidad y la seguridad delos buques: • Movimientos a bordo (operatividad del buque), y • Criterios de estabilidad en condiciones meteorológicas adversas El estudio de la operatividad muestra que los buques accidentados tenían, en general, una mayor operatividad que sus predecesores, contrariamente a lo que sucedía con el cumplimiento de los criterios reglamentarios de estabilidad. Por último, se comprueba el desempeño de los diez buques en dos criterios específicos de estabilidad en caso de mal tiempo: el criterio IMO de viento y balance intenso, y un criterio de estabilidad de nueva generación, incluyendo la contribución original del autor de considerar agua en cubierta. Las tendencias observadas en estas dos comparativas son opuestas, lo que permite cuestionar la validez del último criterio sin un control exhaustivo de los parámetros de su formulación, poniendo de manifiesto la necesidad de más investigaciones sobre ese criterio antes de su adopción para uso regulatorio. El conjunto de estos resultados permite obtener una serie de conclusiones en la comparativa entre ambos conjuntos de buques pesqueros. Si bien los resultados de este trabajo no muestran que la aprobación de la nueva normativa de esfuerzo pesquero haya significado una merma general de seguridad en sectores enteros de la flota pesquera, sí se concluye que permitió que algunos diseños de buques pesqueros, posiblemente en busca de la mayor eficiencia compatible con dicha normativa, quedaran con una estabilidad precaria, poniendo de manifiesto que la relación entre seguridad y criterios de estabilidad no es unívoca, y la necesidad de que éstos evolucionen y se adapten a los nuevos diseños de buques pesqueros para continuar garantizando su seguridad. También se concluye que la estabilidad es un aspecto transversal del diseño de los buques, por lo que cualquier reforma normativa que afecte al diseño de los pesqueros o su forma de operar debería estar sujeta a evaluación por parte de las autoridades responsables de la seguridad marítima con carácter previo a su aprobación. ABSTRACT Between 2004 and 2007 five small Spanish fishing vessels sank in stability related accidents. These vessels had similar characteristics, had relatively short age, and had been built in a period of a few years. Most crewmembers of these five vessels died or disappeared in those accidents. This set of accidents had significant social and media impact. Among naval architects and seamen of the fishing sector these accidents were related to the design constraints imposed by the fishing control effort regulations. The accidents were investigated and the official reports issued; this alleged relationship was not explored. This thesis aims to investigate the relationship between those accidents and changes in fishing effort control regulations. In the introduction, the fishing effort control regulation is exposed, data of the Spanish fishing fleet structure and its accident rates are presented, and stability criteria dealt with in this work are explained, detailing its relationship with fishing vessel safety. A statistical analysis of the accident rates in the fishing sector in Spain is performed afterwards. The objective is determining whether the set of accidents studied constitute an anomaly or, on the contrary, they are not statistically relevant. Fishing vessels accident rates is analyzed from several fishing vessel databases in Spain. It is concluded that the set of studied accidents is statistically relevant, as the probability of occurrence of the five happenings is extremely low, considering the loss rates in the subsector of the Spanish fishing fleet where the studied vessels are fitted within. From this point the thesis focuses in comparing the vessels lost and the vessels that were decommissioned to build them as required by the fishing effort control regulation; these vessels will be referred to as “predecessors” of the sunk vessels. The main dimensions between each lost vessel and her predecessor are compared, leading to the conclusion that the lost vessels share design characteristics which are sensibly different from the predecessors, and linking these design characteristics with the requirements imposed by the new fishing control effort regulations. This allows establishing a relationship between the accidents and this regulation change. Then the margin in fulfilling the regulatory stability criteria among the vessels is compared, resulting, in four of the five cases, that predecessors meet the stability criteria with greater clearance than the sunk vessels. The results obtained at this point would establish a relationship between the change of fishing effort control regulation and the stability of vessels. The five lost vessels complied with the stability criteria in force, so the relation between these criteria and safety is put in question. Consequently, the comparison among vessels is extended to other fields related to safety and stability: • Motions onboard (operability), and • Specific stability criteria in rough weather The operability study shows that the lost vessels had in general greater operability than their predecessors, just the opposite as when comparing stability criteria. Finally, performance under specific rough weather stability criteria is checked. The criteria studied are the IMO Weather Criterion, and one of the 2nd generation stability criteria under development by IMO considering in this last case the presence of water on deck, which is an original contribution by the author. The observed trends in these two cases are opposite, allowing to put into question the last criterion validity without an exhaustive control of its formulation parameters; indicating that further research might be necessary before using it for regulatory purposes. The analysis of this set of results leads to some conclusions when comparing both groups of fishing vessels. While the results obtained are not conclusive in the sense that the entry into force of a new fishing effort control in 1998 caused a generalized safety reduction in whole sectors of the Spanish fishing fleet, it can be concluded that it opened the door for some vessel designs resulting with precarious stability. This evidences that the relation between safety and stability criteria is not univocal, so stability criteria needs to evolve for adapting to new fishing vessels designs so their safety is still guaranteed. It is also concluded that stability is a transversal aspect to ship design and operability, implying that any legislative reform affecting ship design or operating modes should be subjected to assessing by the authorities responsible for marine safety before being adopted.

Durante los últimos años ha aumentado la presencia de personas pertenecientes al mundo de la política en la red debido a la proliferación de las redes sociales, siendo Twitter la que mayor repercusión mediática tiene en este ámbito. El estudio del comportamiento de los políticos en Twitter y de la acogida que tienen entre los ciudadanos proporciona información muy valiosa a la hora de analizar las campañas electorales. De esta forma, se puede estudiar la repercusión real que tienen sus mensajes en los resultados electorales, así como distinguir aquellos comportamientos que tienen una mayor aceptación por parte de la la ciudadaná. Gracias a los avances desarrollados en el campo de la minería de textos, se poseen las herramientas necesarias para analizar un gran volumen de textos y extraer de ellos información de utilidad. Este proyecto tiene como finalidad recopilar una muestra significativa de mensajes de Twitter pertenecientes a los candidatos de los principales partidos políticos que se presentan a las elecciones autonómicas de Madrid en 2015. Estos mensajes, junto con las respuestas de otros usuarios, se han analizado usando algoritmos de aprendizaje automático y aplicando las técnicas de minería de textos más oportunas. Los resultados obtenidos para cada político se han examinado en profundidad y se han presentado mediante tablas y gráficas para facilitar su comprensión.---ABSTRACT---During the past few years the presence on the Internet of people related with politics has increased, due to the proliferation of social networks. Among all existing social networks, Twitter is the one which has the greatest media impact in this field. Therefore, an analysis of the behaviour of politicians in this social network, along with the response from the citizens, gives us very valuable information when analysing electoral campaigns. This way it is possible to know their messages impact in the election results. Moreover, it can be inferred which behaviours have better acceptance among the citizenship. Thanks to the advances achieved in the text mining field, its tools can be used to analyse a great amount of texts and extract from them useful information. The present project aims to collect a significant sample of Twitter messages from the candidates of the principal political parties for the 2015 autonomic elections in Madrid. These messages, as well as the answers received by the other users, have been analysed using machine learning algorithms and applying the most suitable data mining techniques. The results obtained for each politician have been examined in depth and have been presented using tables and graphs to make its understanding easier.

Audiovisuelle Bildungsmedienformate und ihre Lernerfolge – eine Paneldatenstudie zum Nachmachen

Visuelle Bildungsmedien erfahren wachsende Verbreitung in der universitären Lehre, und die Anzahl der verwendeten Medienformate steigt. Wir untersuchen empirisch den Lernerfolg dreier Formate - Lehrvideo plus Folien/Folien plus Audio/Audio - und stellen fest, dass der Lernerfolg die aufwändige Medienproduktion nicht in jedem Fall rechtfertigt. Das Untersuchungsdesign lädt zum Nachmachen und somit zum Ermitteln des geeignetsten Medienformats in einem spezifischen Lehrkontext ein. (DIPF/Orig.)

Regards sur les territoires des ancrages haïtiano-montréalais : les impacts des pratiques transnationales au quotidien

À Montréal, les Haïtiens forment le troisième groupe ethnique en importance et offrent un exemple de peuple en diaspora. Étudier leurs mobilités et pratiques transnationales, ainsi que leurs incidences sur la redéfinition des concepts d’identité et de territoire, permet alors de comprendre les articulations entre le local et le transnational, dans le contexte de globalisation et de rétrécissement du monde permis par les nouvelles technologies. L’objectif de la recherche est de comprendre l’impact des pratiques transnationales et des médias dans la construction territoriale et l’ancrage des Haïtiens montréalais. Pour ce faire, 18 entrevues de type récit de vie ont été menées auprès d’un échantillon représentant les différentes vagues d’immigration haïtienne et des tables rondes ont été organisées. L’analyse des discours a permis de mettre en lumière les trajectoires, les lieux et types d’ancrages ainsi que le rôle des nouvelles technologies dans les liens translocaux de cette communauté. Les résultats, non généralisables, mettent de l’avant le rôle important des médias dans l’ancrage. Par exemple, l’ancrage des migrants de la première vague a été facilité par la création de radios haïtiennes, ces dernières ayant aidé à cimenter la communauté d’alors. Pour les deuxièmes générations, les nouveaux médias permettent de s’identifier à la diaspora et de s’ancrer en Haïti, avec des projets de développement, comme à Montréal, à travers l’expérience du cosmopolitisme. Finalement, l’analyse des récits de vie des nouveaux arrivants le confirme : les médias donnent la possibilité d’un ancrage inédit gardé à disposition avec les nouvelles technologies d’information et de communication.

Social media and its impact on crisis communication: Case studies of Twitter use in emergency management in Australia and New Zealand

There is a growing awareness worldwide of the significance of social media to communication in times of both natural and human-created disasters and crises. While the media have long been used as a means of broadcasting messages to communities in times of crisis – bushfires, floods, earthquakes etc. – the significance of social media in enabling many-to-many communication through ubiquitous networked computing and mobile media devices is becoming increasingly important in the fields of disaster and emergency management. This paper undertakes an analysis of the uses made of social media during two recent natural disasters: the January 2011 floods in Brisbane and South-East Queensland in Australia, and the February 2011 earthquake in Christchurch, New Zealand. It is part of a wider project being undertaken by a research team based at the Queensland University of Technology in Brisbane, Australia, that is working with the Queensland Department of Community Safety (DCS) and the EIDOS Institute, and funded by the Australian Research Council (ARC) through its Linkages program. The project combines large-scale, quantitative social media tracking and analysis techniques with qualitative cultural analysis of communication efforts by citizens and officials, to enable both emergency management authorities and news media organisations to develop, implement, and evaluate new social media strategies for emergency communication.

The impact of personal identity and intimacy on the use of social media

Personal identity and intimacy levels change over time and this can influence the way consumers buy and use goods and services. This thesis examined how levels of personal identity and intimacy influence the use of social media by consumers of different ages. A survey of 208 users of facebook demonstrated that consumers with weak levels of personal identity use social media to increase their identity and popularity, while consumers with strong levels of personal identity use social media for self-expression. Consumers with high intimacy levels use social media for socian connection and social investigation.

The impact of social media features on print media firms’ online business models

Many newspapers and magazines have added “social media features” to their web-based information services in order to allow users to participate in the production of content. This study examines the specific impact of the firm’s investment in social media features on their online business models. We make a comparative case study of four Scandinavian print media firms that have added social media features to their online services. We show how social media features lead to online business model innovation, particularly linked to the firms’ value propositions. The paper discusses the repercussions of this transformation on firms’ relationship with consumers and with traditional content contributors. The modified value proposition also requires firms to acquire new competences in order to reap full benefit of their social media investments. We show that the firms have been unable to do so since they have not allowed the social media features to affect their online revenue models.
