Optimal pricing strategies in real-time electricity pricing environments: An Italian case study
2015
The energy market has changed radically over the last decade, mainly due to an increased penetration of renewable energies. Now the end users have directly access to the energy market and can actively take part to the electricity market. Electricity customers can indeed modify their behavior through Demand Response (DR), namely by means of pricing strategies that support a change in the end-users habits. This can be accomplished through a 'loads aggregator', a third party that collects the requests and signals for Active Demand-based services coming from the markets and the different power system participants. This paper describes a new framework able to optimally select the real-time prici…
An algorithm for simulating end-user behaviour in a real time pricing market

Real-time pricing for aggregates energy resources in the Italian energy market
2015
Abstract Over the last decade, the architecture of the energy market has radically changed. In many countries end-users are now able to directly access the market, which has given rise to the question of how they can actively participate in that market. End-users can comprise a critical mass through aggregation that is carried out by a third party – to wit the “loads aggregator.” This paper proposes a new framework for generating feasible real-time price curves for those end-users in a demand-response management process. The underlying algorithm generates output curves as the solution to a constrained optimization problem whose objective function is the aggregator's economic benefit. A case…
Generation Z and Organizational Listening on Social Media
2020
Young people are avid users of social media and have appeared as a powerful force for social change, as shown by the ranks of those who have joined Greta Thunberg in the global climate movement. In addition to challenging political institutions and governments, young people today are also holding the corporate world accountable. To respond to young people’s expectations, brands, and organizations have turned to social media to interact and build relationships with them. However, critics have lamented that these attempts often fail and that young people’s trust in institutions, brands, and organizations continues to decline. This article asks how young people perceive organizational listenin…
Representation of the Israeli-Palestinian conflict in American newspapers
2015
Israelin ja Palestiinan välinen kiista maa-alueesta on johtanut yhteen modernin historian pitkittyneimmistä ja väkivaltaisimmista konflikteista. Kesäkuussa 2014 väkivaltaisuudet leimahtivat jälleen Gazassa, ja siviiliuhrien määrä oli suurin lähes 50 vuoteen. Tapahtumat saivat runsasta mediahuomiota ympäri maailman. Konfliktin uutisointi on ollut usean akateemisen tutkielman kohteena, ja monissa tapauksissa se on havaittu jossain määrin puolueelliseksi. Näihin lukeutuu esimerkiksi Aziza Zaherin kriittinen diskurssintutkimus länsimaisista ja arabilehdistä. Analyysi sanastosta, narratiiveista sekä transitiivisuudesta näytti, että uutisointi ei ollut puolueetonta ja ennakkoluulotonta, toisin ku…
The Polarizing Impact of News Coverage on Populist Attitudes in the Public: Evidence From a Panel Study in Four European Democracies
2017
This study explores how news messages carrying parts of the populist ideology contribute to a polarization of public opinion about populism. It combines a content analysis of news coverage on two policy areas (N = 7,119 stories) with a two-wave panel survey (N = 2,338) in four European metropolitan regions (Berlin, Paris, London, and Zurich). In three regions, unopposed media messages with a populist stance have a conditional effect on populist attitudes that depends on prior convictions. A higher dose of exposure to populist news coverage enhances both prior agreement and disagreement with populism. Although the observed interaction patterns vary between regions, the general picture sugges…
The Effects of Right-Wing Populist Communication on Emotions and Cognitions toward Immigrants
2018
The persuasiveness of right-wing populist communication has become a widely discussed topic; it is often assumed that such messages might foster anti-immigrant attitudes among citizens. The present study explores the effects of the different components of right-wing populist communication—anti-immigrant messages, populist content, and populist style—on attitudes toward immigrants. By combining a media content analysis ( N = 605 articles) with a panel survey ( N = 1,968) in metropolitan areas of four Western European countries (France, Germany, Switzerland, and the United Kingdom), this study analyzes how citizens’ attitudes toward immigrants are influenced by the right-wing populist commun…
New Roles for Media in the Western Balkans
2017
After almost 20 years of political instability and ongoing conflicts in the Western Balkans, the region is still haunted by the past, and there is an ongoing synergy of influence between media and the political sector. Media in this region have frequently been criticized for fueling conflicts, instigating ethnic hatred and taking political sides. This article suggests a new research agenda in the practice of transitional journalism in this part of Southeastern Europe. This research strand combines elements from troubled pasts, war reporting, peace journalism and issues of transitional justice. This article analyzes how journalists in the Western Balkans consider the roles of journalism in t…
The effects of populism as a social identity frame on persuasion and mobilization: evidence from a 15-country experiment
2020
This article investigates the impact of populist messages on issue agreement and readiness for action in 15 countries (N = 7,286). Specifically, populist communicators rely on persuasive strategies by which social group cues become more salient and affect people's judgment of and political engagement with political issues. This strategy is called ‘populist identity framing’ because the ordinary people as the in‐group is portrayed as being threatened by various out‐groups. By blaming political elites for societal or economic problems harming ordinary people, populist communicators engage in anti‐elitist identity framing. Another strategy is to blame immigrants for social problems – that is, …
