Through a post-political gaze : on the ideological loading of democracy in the coverage of Chávez's Venezuela
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Rooted in ideology critique, this dissertation studies the construction of democracy in the coverage of Venezuela during the era of President Hugo Chávez. The aim of this endeavor is twofold. First, the dissertation aims to understand the relationship between ideology and the construction of democracy in journalism on foreign political phenomena. Second, it attempts to explore the ways in which the relationship between ideology and democracy in journalism serves to legitimize or delegitimize the struggle for social justice in nations in the global South vis-à-vis the political and economic fundamentals of global capitalism.The dissertation comprises three articles that study the construction of democracy in depictions of the Venezuelan political system and its key political actors. Article I studies the construction of (il)legitimate democracy in relation to the Venezuelan government, Article II explores the construction of difference between Chávez’s supporters and his opponents, and Article III studies the coverage of the coup d’état against Chávez in 2002. All three articles are methodologically rooted in critical discourse analysis and rely on materials from a sample of three elite newspapers: Dagens Nyheter (Sweden), El País (Uruguay), and the New York Times (US).Across the studies, there are four macro-strategies that in different ways serve to ideologically load the notion of democracy. Three of these strategies – the constructs of populism, of power concentration and of difference – serve to define political deviance and to (de)legitimize political actors in relation to democracy. The fourth macro-strategy, relativization, serves to justify actions that contradict established democratic principles but serve greater politico-ideological goals.(De)legitimation in relation to democracy corresponds with the closeness of a group of actors to the dominant political practices and values within global capitalism. Journalistic reporting thus follows a post-political gaze; it is generally in accordance with the political consensus that characterizes the post-Cold War era. Through this gaze, any challenge to the political tenets of global capitalism fails on democratic grounds.

- This study aims to explore the construction of difference in foreign news discourse on culturally similar but politically different non-Western subjects. Applying critical discourse analysis (CDA) together with a critique of Eurocentrism, the study examines difference in newspaper constructions of government supporters and oppositional groups in Venezuela. Discursive differences are evident in the strategies used for constructing the two groups with regard to political rationality and violence. Government supporters are associated with social justice, Venezuela's poor, dogmatic behavior, and the use of political violence. The opposition, in contrast, is constructed as following a Western democratic rationale that stresses anti-authoritarianism. This group is primarily associated with victims of violence. While the opposition is conveyed as being compatible with Eurocentric values and practices, government supporters to great extent deviate from these norms. Such constructions serve to legitimize politico-ideological undercurrents of Eurocentrism, as the defense of liberalism.

- The first worldwide interlaboratory assesment on persistent organic pollutants (POPs) under the Stockholm Convention was organized in the Asian/Pacific, Latin American and African regions during 2009-11.A relatively large number of laboratories reported data for the PCDDs/PCDFs and dioxin-like PCBs, especially in the Asian region. Within the Asian region, several participants used high-resolution GC/high-resolution MS systems optimized for dioxin analysis. The availibility of High-resolution mass spectrometer instrumentation is limited in the Latin America and African regions, although recently several new laboratories for dioxins have started in the Latin American region.

Tidskriftsartikel (refereegranskat)abstract
- This conceptual article discusses and, from some aspects, also problematizes the state-of-the-art regarding co-evolutionary research in Management and Organization Studies (MOS). Analyzing 76 characteristic studies published since 2000, we address three simple, significant questions: What co-evolves? What causal relationships are considered? What are the theoretical processes? The motivation behind our contribution is twofold: on the one hand, the turn of the century witnessed the remarkable growth of inquiries which, at face value, have claimed to be “co-evolutionary”; but, on the other hand, specific analyses about where this fast-growing meta-theoretical perspective on social change is now, and where it could move towards in the future, are still missing in MOS. Our study reveals increasing heterogeneity in defining what co-evolves and the associated causal relationships. It also reveals the prevailing scarcity in explaining what processes substantially characterize co-evolution in MOS. With a view to shaping the future direction of research in this area, we propose four core principles that theoretically set the co-evolutionary project apart.

- How can cognitive biases affect the birth and evolution of entrepreneurial ventures? In Entrepreneurial Decision Making (EDM), this lively research question remains largely unaddressed when the world of Unicorns, as a per se entrepreneurial species, is considered. Thus, through this conceptual article, we aim to contribute toward knowledge creation in this context. We start by proposing a conceptual framework of Unicorns’ EDM based on a behavioral approach. Through three propositions, this novel framework advances how the birth, transition, and consolidation of a Unicorn may be explained by the sequentially intertwined occurrence of biases, from which establishment and legitimization eventually emerge. We complement the framework with examples from the social media industry and then discuss its main implications for theory and practice.

- INTRODUCTION: There is no consensus on the impact of coronary artery disease in patients undergoing transcatheter aortic valve implantation. Therefore, the objective of this study was, in a single-center setting, to evaluate the five-year outcome of transcatheter aortic valve implantation patients with or without coronary artery disease.METHODS: All transcatheter aortic valve implantation patients between 2009 and 2019 were included and grouped according to the presence or absence of coronary artery disease. The primary endpoint, five-year all-cause mortality, was evaluated using Cox regression adjusted for age, sex, procedure years, and comorbidities. Comorbidities interacting with coronary artery disease were evaluated with interaction tests. In-hospital complications was the secondary endpoint.RESULTS: In total, 176 patients had aortic stenosis and concomitant coronary artery disease, while 170 patients had aortic stenosis only. Mean follow-up was 2.2±1.6 years. There was no difference in the adjusted five-year all-cause mortality between transcatheter aortic valve implantation patients with and without coronary artery disease (hazard ratio 1.00, 95% confidence interval 0.59-1.70, P=0.99). In coronary artery disease patients, impaired renal function, peripheral arterial disease, or ejection fraction < 50% showed a significant interaction effect with higher five-year all-cause mortality. No significant differences in complications between the groups were found.CONCLUSION: Five-year mortality did not differ between transcatheter aortic valve implantation patients with or without coronary artery disease. However, in patients with coronary artery disease and impaired renal function, peripheral arterial disease, or ejection fraction < 50%, we found significantly higher five-year all-cause mortality.

- Context: Polycystic ovary syndrome (PCOS) is a heterogeneous condition affecting women of reproductive age. It is associated with dyslipidaemia and elevated plasma C-reactive protein (CRP), which increase the risks of cardiovascular disease (CVD).Objective: To review the existing evidence on the effects of different pharmacological interventions on lipid profiles and CRP of women with PCOS.Data Sources: We searched PubMed, MEDLINE, Scopus, Embase, Cochrane Library, and Web of Science in April 2020 and updated the results in March 2021.Study Selection: The study included randomized controlled trials (RCTs) and follows the 2020 Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA).Data Extraction: Two independent researchers extracted data and assessed for risk of bias using the Cochrane risk of bias tool. Covidence systematic review software were used for blinded screening and study selection.Data Synthesis: In 29 RCTs, there were significant reductions in triglycerides with atorvastatin versus placebo [mean difference (MD): -0.21 mmol/L; 95% confidence interval (CI): -0.39, -0.03, I-2 = 0%, moderate grade evidence]. Significant reductions were seen for low-density lipoprotein cholesterol (LDL-C) with metformin versus placebo [standardized mean difference (SMD): -0.41; 95% CI: -0.85, 0.02, I-2 = 59%, low grade evidence]. Significant reductions were also seen for total cholesterol with saxagliptin versus metformin (MD: -0.15 mmol/L; 95% CI: -0.23, -0.08, I-2 = 0%, very low grade evidence). Significant reductions in C-reactive protein (CRP) were seen for atorvastatin versus placebo (MD: -1.51 mmol/L; 95% CI: -3.26 to 0.24, I-2 = 75%, very low-grade evidence).Conclusion: There were significant reductions in the lipid parameters when metformin, atorvastatin, saxagliptin, rosiglitazone and pioglitazone were compared with placebo or other agents. There was also a significant reduction of CRP with atorvastatin.
