Automating enterprise architecture documentation using an enterprise service bus
- 2012
-
In: 18th Americas Conference on Information Systems 2012, AMCIS 2012. ; , s. 4213-4226
-
Conference paper (peer-reviewed)abstract
- Currently the documentation of Enterprise Architectures (EA) requires manual collection of data resulting in an error prone, expensive, and time consuming process. Recent approaches seek to automate and improve EA documentation by employing the productive system environment of organizations. In this paper, we investigate a specific Enterprise Service Bus (ESB) considered as the nervous system of an enterprise interconnecting business applications and processes as an information source. We evaluate the degree of coverage to which data of a productive system can be used for EA documentation. A vendor-specific ESB data model is reverse-engineered and transformation rules for three representative EA information models are derived. These transformation rules are employed to perform automated model transformations making the first step towards an automated EA documentation. We evaluate our approach using a productive ESB system from a leading enterprise of the fashion industry.

Start Spreading the News: A Comparative Experiment on the Effects of Populist Communication on Political Engagement in Sixteen European Countries
- 2018
-
In: International Journal of Press-Politics. - : SAGE Publications. - 1940-1612 .- 1940-1620. ; 23:4, s. 517-538
-
Journal article (peer-reviewed)abstract
- Although populist communication has become pervasive throughout Europe, many important questions on its political consequences remain unanswered. First, previous research has neglected the differential effects of populist communication on the Left and Right. Second, internationally comparative studies are missing. Finally, previous research mostly studied attitudinal outcomes, neglecting behavioral effects. To address these key issues, this paper draws on a unique, extensive, and comparative experiment in sixteen European countries (N = 15,412) to test the effects of populist communication on political engagement. The findings show that anti-elitist populism has the strongest mobilizing effects, and anti-immigrant messages have the strongest demobilizing effects. Moreover, national conditions such as the level of unemployment and the electoral success of the populist Left and Right condition the impact of populist communication. These findings provide important insights into the persuasiveness of populist messages spread throughout the European continent.

Trends of intense cyclone activity in the Arctic from reanalyses data and regional climate models (Arctic-CORDEX)
- 2019. - 1
-
In: Turbulence, Atmosphere and Climate Dynamics. - : IOP Publishing. - 1755-1307. ; 231
-
Conference paper (peer-reviewed)abstract
- The ability of state-of-the-art regional climate models (RCMs) to simulate the trends of intense cyclone activity in the Arctic is assessed based on an ensemble of 13 simulations from 11 models from the Arctic-CORDEX initiative. Some models employ large-scale spectral nudging techniques. Cyclone characteristics simulated by the ensemble in winter and summer are compared with the results from four reanalyses (ERA-Interim, NCEP-CFSR, NASA-MERRA2 and JMA-JRA55) in winter and summer for 1981-2010 period.

A pattern-based approach to quantitative enterprise architecture analysis
- 2009
-
In: 15th Americas Conference on Information Systems 2009, AMCIS 2009. - 9781615675814 ; , s. 2314-2324
-
Conference paper (peer-reviewed)abstract
- Enterprise Architecture (EA) management involves tasks that substantially contribute to the operations of an enterprise, and to its sustainable market presence. One important aspect of this is the availability of services to customers. However, the increasing interconnectedness of systems with other systems and with business processes makes it difficult to get a clear view on change impacts and dependency structures. While management level decision makers need this information to make sound decisions, EA models often do not include quality attributes (such as availability), and very rarely provide quantitative means to assess them. We address these shortcomings by augmenting an information model for EA modeling with concepts from Probabilistic Relational Models, thus enabling quantitative analysis. A sample business case is evaluated as an example of the technique, showing how decision makers can benefit from information on availability impacts on enterprise business services.

Navigating High-Choice European Political Information Environments: A Comparative Analysis of News User Profiles and Political Knowledge
- 2022
-
In: The International Journal of Press/Politics. - : SAGE Publications. - 1940-1612 .- 1940-1620. ; 27:4, s. 827-859
-
Journal article (peer-reviewed)abstract
- The transition from low- to high-choice media environments has had far-reaching implications for citizens’ media use and its relationship with political knowledge. However, there is still a lack of comparative research on how citizens combine the usage of different media and how that is related to political knowledge. To fill this void, we use a unique cross-national survey about the online and offline media use habits of more than 28,000 individuals in 17 European countries. Our aim is to (i) pro- file different types of news consumers and (ii) understand how each user profile is linked to political knowledge acquisition. Our results show that five user profiles – news minimalists, social media news users, traditionalists, online news seekers, and hyper news consumers – can be identified, although the prevalence of these profiles varies across countries. Findings further show that both traditional and online-based news diets are correlated with higher political knowledge. However, online-based news use is more widespread in Southern Europe, where it is associated with lower levels of political knowledge than in Northern Europe. By focusing on news audiences, this study provides a comprehensive and fine-grained analysis of how contemporary European political information environments perform and contribute to an informed citizenry.

Misinformation Detection in the Context of the Russian Invasion of Ukraine: Evidence From Original Survey Data Collected in 19 Democracies
- 2024
-
In: International Journal of Public Opinion Research. - 0954-2892 .- 1471-6909. ; 36:3, s. 1-12
-
Journal article (peer-reviewed)abstract
- It can be difficult for citizens to discern factually accurate information from mis- and disinformation. Particularly in the context of the Russian invasion of Ukraine, the omnipresence of counterfactual narratives, propaganda, and partisan content may increase the likelihood that citizensselect and accept mis -or disinformation. To assess citizens’ performance in discerning false statements from factually accurate information on the war, we utilized original survey data across 19 countries (N = 19,037) with soft quotas for age, education, and gender to approximate population characteristics. Our main findings indicate that people perform relatively well in discerning factually accurate information from false statements and that self-perceived media literacy and the need for cognition corresponds with better performance. Stronger pro-Russia views on the war correspond with a lower performance in misinformation detection, whereas anti-Russia attitudes are associated with better evaluations of the statements’ truthfulness. We find little cross-country variation in these patterns. As a key implication, we show that discernment between factually accurate information and mis- or disinformation is driven by both accuracy and partisan motivation and that these effects are similar across most different national contexts.

Treatment of CD40 ligand deficiency by hematopoietic stem cell transplantation: a survey of the European experience, 1993-2002
- 2004
-
In: Blood. - : American Society of Hematology. - 0006-4971 .- 1528-0020. ; 103:3, s. 1152-7
-
Journal article (peer-reviewed)abstract
- CD40 ligand (CD40L) deficiency causes recurrent sinopulmonary infection, Pneumocystis carinii pneumonia, and Cryptosporidium parvum infection. Approximately 40% to 50% of patients survive to the third decade: long-term survival is unclear. Hematopoietic stem cell transplantation (HSCT) is curative. We present a retrospective analysis of 38 European patients undergoing HSCT for CD40L deficiency in 8 European countries between 1993 and 2002. Donor stem cell source included 14 HLA-identical siblings, 22 unrelated donors, and 2 phenotypically matched parental stem cells (12 T-cell depleted). Of the patients, 34 engrafted and 26 (68%) survived; 3 had autologous reconstitution, 22 (58%) were cured, and 1 engrafted but has poor T-cell immune reconstitution. There were 18 evaluated patients who responded to vaccination. Of the patients, 12 (32%) died from infection-related complications, with severe cryptosporidiosis in 6. Grades 2 to 4 graft-versus-host disease (GvHD) associated with infection occurred in 6 of 12 fatal cases. HSCT cured 58% of patients, 72% of those without hepatic disease. Early T-cell function following whole marrow HSCT may limit cryptosporidial disease, but survival was similar after T-cell-depleted HSCT. Preexisting lung damage was the most important adverse risk factor. Further studies will determine optimal timing and type of HSCT.

Perceived prevalence of misinformation fuels worries about COVID-19: a cross-country, multi- method investigation
- 2023
-
In: Information, Communication and Society. - : Informa UK Limited. - 1369-118X .- 1468-4462. ; 26:16, s. 3135-3158
-
Journal article (peer-reviewed)abstract
- Data suggests that the majority of citizens in various countries came across ‘fake news’ during the COVID-19 pandemic. We test the relationship between perceived prevalence of misinformation and people’s worries about COVID-19. In Study 1, analyses of a survey across 17 countries indicate a positive association: perceptions of high prevalence of misinformation are correlated with high worries about COVID-19. However, the relationship is weaker in countries with higher levels of case-fatality ratios, and independent from the actual amount of misinformation per country. Study 2 replicates the relationship using experimental data. Furthermore, Study 2 demonstrates the underlying mechanism, that is, perceived prevalence of misinformation fosters the belief that COVID-19 is spiralling out of control, which in turn, increases worries. Our findings suggest that perceived prevalence of misinformation can have significant psychological effects, even though audience members reject the information as being false.

Justifying an Invasion: When Is Disinformation Successful?
- 2024
-
In: Political Communication. - 1058-4609 .- 1091-7675.
-
Journal article (peer-reviewed)abstract
- Conventional wisdom suggests that social media, especially when used by authoritarian powers with nefarious aims, leaves citizens of democratic countries vulnerable to psychological influence campaigns. But such concerns overlook predispositions among recipients of false claims to reject (or to endorse) conspiratorial narratives. Analyzing responses from a survey fielded in 19 countries, we find that it is a preexisting conspiracy outlook at the individual level, more so than media diets, which consistently predicts rating Russia’s pretenses for the invasion as more accurate. In all countries, individuals who view the world in general with a conspiratorial mindset are more likely to believe war-related disinformation. Receiving news via YouTube, Facebook, or TikTok is also associated with greater belief in Russian narratives justifying the invasion in several countries, but these relationships are weaker compared to those observed for conspiracy thinking. Without downplaying a potential positive role for media interventions, the findings highlight the importance of a deeper understanding of the underlying causes of conspiratorial thinking.

The Effects of the COVID-19 Outbreak on Selective Exposure: Evidence from 17 Countries
- 2022
-
In: Political Communication. - : Informa UK Limited. - 1058-4609 .- 1091-7675. ; 39:5
-
Journal article (peer-reviewed)abstract
- A widely believed claim is that citizens tend to selectively expose themselves to like-minded information. However, when individuals find the information useful, they are more likely to consume cross- cutting sources. While crises such as terror attacks and pandemics can enhance the utility of cross-cutting information, empirical evidence on the role of real-world external threats in selective exposure is scarce. This paper examines the COVID-19 pandemic as a case study to test the extent to which citizens were exposed to information from cross- cutting sources on traditional and social media after the outbreak. Utilizing a two-wave panel survey among 14,218 participants across 17 countries – conducted before and after the initial outbreak – we show that citizens concerned about COVID-19 were more exposed to cross-cutting information on traditional and social media. The positive relationship with cross-cutting exposure to traditional news was stron- ger in countries where governments adopted less stringent policy responses, and in countries with greater pandemic severity and weaker democratic institutions. Our comparative approach thus sheds light on the social and political contexts in which cross-cutting exposure can occur.
