    Full text link
    Abstract Digital media in general, and social media in particular, are a distinctive feature of contemporary election campaign strategies. This article adds to the on going discussion of the political power of social media by exploring political party strategies behind the usage of social media. In this study we specifically focus on Twitter (a micro blog) during the latest National Election Campaign in Sweden in 2010. The study exams the degree and character of Twitter usage among parties and prominent party members, and relates content to the declared communication strategies regarding the role of Twitter in the campaign. Methodologically, the paper is based on a quantitative content analysis of all party tweets and on personal interviews with all party campaign managers. The results show campaign purposes. However, the content analysis confirms only a modest party use of Twitter messages and Twitter patterns where messages are most often related to current news media activities and are of a one-way character, with more focus on information dissemination than on interactive dialogue with voters

    This article discusses the relationship between the newspaper market structure in a region and the diversity of local news. It introduces some partial results on studies based on substantial media concentration within two very different regiona newspaper markets in the North and in the South of Sweden. The findings suggest that the relationship between newspaper competition and local news diversity is rather complicated. The study gives some support to the thought that ruinous competition sometimes could be as bad for news diversity as monopoly media.Este art铆culo trata sobre la relaci贸n entre la estructura de mercado regional para los peri贸dicos impresos y la diversidad de las noticias locales. Presenta los resultados parciales de algunos estudios basados en la concentraci贸n de medios impresos en dos mercados regionales muy diferentes en el Norte y el Sur de Suecia. Los hallazgos sugieren que la relaci贸n entre la competencia entre los diarios y la diversidad de las noticias locales es m谩s bien compleja. El estudio sustenta, asimismo, la idea de que la competencia destructiva en ocasiones puede ser tan negativa para la diversidad en la informaci贸n como los mercados monopol铆sticos

    Media systems theory (Hallin & Mancini, 2004, 2017) has been a productive theoretical framework for understanding the relationship between media and politics in a compara-tive perspective. Recent developments in the growing research field have suggested that the democratic corporatist media system model is not one-model-fits-all with regard to the northern European countries (Br眉ggemann et al., 2014; Nord, 2008; Ohlsson, 2015; Syvertsen et al., 2014). However, empirical studies of the media systems of the Nordic countries tend to have the larger Nordic countries 鈥 Norway, Finland, Sweden, and Denmark 鈥 as their object, leaving us with little research on the smaller media systems in 鈥渢he other鈥 Nordic countries and autonomous regions. The grand question still to be answered is whether we can speak of one or a Nordic media system, or whether there are differences from west to east or from north to south? What has our shared Nordic history meant in relation to the development of our media systems, and are there differences between the smaller and larger Nordic countries? Are we as alike as we might think

    Ten years after : Is the party-centered theory of campaign professionalization still valid?

    This study tests the explanatory strength of the party-centered theory of electoral campaign professionalism. The theory was previously subject to testing in various types of elections during the first decade of the new millennium, covering Germany, Austria, Sweden, and Finland. Nevertheless, empirical research in this field has been on hold for almost a decade, obstructing the development of the theory during a time when politics and political campaigns have taken new paths. In this article, the theory is revisited, presenting results from a unique time series study covering 48 party campaigns between 2009 and 2019 in three consecutive European parliamentary elections in two multiparty democracies, Sweden and Finland. Our results provide weak support for the party-centered theory of campaign professionalism in the form it was originally operationalized. Only a centralized party organization and a large support base with a catch-all strategy were found to be statistically significant predictors of campaign professionalism.Peer reviewe

    Statistical arbitrage in the freight options market : applying trading strategies to profit from volatility misspecification in the dry bulk shipping industry

    Get PDF
    The purpose of this thesis is to investigate trading strategies that can exploit misspecification of volatility in the freight options market. We have, using observed market prices, derived smooth forward rate curves from daily observations. These forward curves promote a representation of the historical volatility term structures for the Capesize, Panamax, and Supramax sub-sector of the dry-bulk shipping industry. The volatility term structures present consistent behavior across vessel sizes, with increasing volatility over a six week time horizon before the volatility converges towards an apparent long term equilibrium. The dynamics coincides with the general belief that spot freight rates are mean reverting in the long term and positively auto-correlated in the short term. A comparison of the historical volatility term structure and the volatility estimates implied by the options market reveals differences. Based on deviating volatility estimates, we execute trading strategies in what we believe is a realistic representation of the market dynamics. Our findings can be interpreted as a sign of inefficiency in the freight options market. Keywords 鈥 Forward freight agreements, dry bulk, volatility term structure, volatility tradingnhhma

    Investigation of control strategies for adsorption-based CO2 capture from a thermal power plant under variable load operation

    Get PDF
    This work considers the closed-loop behavior of a moving bed temperature swing adsorption process designed to capture CO2 from a coal-fired power plant. Four decentralized control strategies were studied based on step changes and ramps of flue gas feed flow rate and controller setpoint changes. A proportional-integral (PI) control configuration, where CO2 purity was controlled by hot fluid velocity to the desorption section and CO2 recovery was controlled by the sorbent flow rate, demonstrated the overall best performance. The 99% settling time for higher-level control variables varied from 0 to 13 min for most control configurations and the settling time for CO2 purity was generally longer than for CO2 recovery. The simulations show that using ratio controllers lead to larger offsets but can give around 10 times faster purity response compared to PI-control. All investigated control combinations were able to keep the controlled variables relatively close to the setpoints and the largest relative steady state setpoint offset was 2%.publishedVersio

    Responses and relationship dynamics of men and their spouses during active surveillance for prostate cancer: health literacy as an inquiry framework

    Full text link
    BACKGROUND: Early stage prostate cancer patients may be allocated to active surveillance, where the condition is observed over time with no intervention. Living with a cancer diagnosis may impose stress on both the men and their spouses. In this study we explore whether the scores of and verbal responses to a Health Literacy Questionnaire can be used to identify individuals in need of information and support and to reveal differences in perception and understanding in health related situations within couples. METHODS: We used the nine-domain Health Literacy Questionnaire (HLQ) as a framework to explore health literacy in eight couples where the men were on active surveillance for prostate cancer progression. Scores were calculated for each domain for both individuals. For each couple differences in scores were also calculated and related to the informants\u27 self-reported experiences and reflections in relation to participating in an active surveillance program. Also an inductive analysis was performed to identify themes in the responses and these themes were compared to those of HLQ. RESULTS: The men tended to score higher than their spouses. There was no consistent relation between scores and the reported experiences and reflections. However, some interesting patterns emerged, e.g. in two of the three couples with the largest within couple differences in HLQ scores, responses revealed discrepancies in how the men and their spouses perceived their situation. Also, three themes emerged which related to six of the HLQ domains, i.e. involvement of spouses and other people around the men; support from and interaction with healthcare professionals; and use of the Internet for information retrieval. CONCLUSIONS: Using the HLQ as an interview framework provided insight into the differences within couples and provided new perspectives on their experiences, including their contact with health professionals and the patient-spouse interaction when dealing with prostate cancer. The HLQ used as a dialogue tool may be an adjunct to assist healthcare providers to understand the need for support and information of men with prostate cancer on active surveillance and the dynamics within couples
