Solving the Surveillance Problem : Media Debates About Unwanted Surveillance in Finland
2017
This chapter examines the way surveillance is discussed in the leading Finnish newspaper Helsingin Sanomat after the revelations made by former NSA-contractor Edward Snowden. In 2013, Snowden provided journalists with documents that revealed the unexpected extent of surveillance conducted by security agencies such as the NSA. Drawing on Critical Discourse Studies and a Foucauldian view of discourse, this article understands media discussions following the Snowden revelations as discursive struggles where the legitimacy and future of surveillance are being constructed and debated. The article examines the ways the media formulates solutions to the problems posed by surveillance, and explores…
(De)legitimating electronic surveillance : a critical discourse analysis of the Finnish news coverage of the Edward Snowden revelations
2017
In 2013, ex-National Security Agency (NSA) contractor Edward Snowden shocked the world by revealing the American NSA’s (and its partners’) extensive surveillance programs. The ensuing media discussion became a focal point for the justification and contestation of surveillance in the digital age. This article contributes to the growing body of literature on the discursive construction of surveillance, concentrating on how the practice is (de)legitimized. Methodologically, the paper draws on Critical Discourse Studies, applying the concept of discourse and utilizing insights from Van Leeuwen’s categories of legitimation and social actor representation. The data come from the media coverage of…
Simulation of left ventricular outflow tract (LVOT) obstruction in transcatheter mitral valve-in-ring replacement.
2020
Left ventricular outflow tract (LVOT) obstruction is a feared complication of transcatheter mitral valve replacement (TMVR). This procedure leads to an elongation of LVOT in the left ventricle (namely, the neoLVOT), ultimately portending hemodynamic impairment and death. This study sought to understand the biomechanical implications of LVOT obstruction in two patients who underwent TMVR as an "off-label" application of the Edwards SAPIEN 3 (S3) Ultra transcatheter heart valve (THV). A computational framework of TMVR was developed to assess the neoLVOT area and quantify the sub-aortic flow structure. We observed that the annuloplasty ring serves as the key anchor zone of S3 Ultra THV. A good…
CAD Modeling for Evaluating LVOT Obstruction in Transcatheter Mitral Valve Replacement
2019
The current generation of transcatheter heart valves (THV), as the Edwards SAPIEN 3 Ultra (S3), is not specifically designed for mitral position implantation and has intrinsic design geometry that may make mitral implantation suboptimal. This study aimed to develop a computed-tomography (CT) based CAD workflow for the preoperative planning of transcatheter mitral valve replacement (TMVR) by evaluating the resulting obstruction in the left ventricular outflow tract (LVOT). Specifically, the computational framework to reconstruct heart anatomy and virtually deploy the THV into mitral valve annulus was developed and successively applied to the cases of two patients who experienced annuloplasty…
Constructing images of great power politics : a comparative study on the visual representations of British and German political institutions in polit…

Tutkielma selvittää Iso-Britannian ja Saksan poliittisten järjestelmien arvioimista ja mielikuvien luomista pilakuvissa 1900-luvun alun poliittisesti epävakaissa oloissa. Pilakuvien kautta piirtäjät toivat ilmi näkemyksiä ajan puolueista ja poliitikoista, näin vahvistaen olemassa olevia näkemyksiä, luoden uusia mielikuvia ja esittäen kritiikkiä. Tutkimuskohteina ovat valtion monarkkia, hallitusta ja poliittisia puolueita käsittelevät pilakuvat. Käyttämällä vertailevaa kuva-analyysiä, selvitetään minkälaisia käsityksiä valtioiden porvaristolle esitetään heidän poliittisista järjestelmistään ja järjestelmän sisäisten instituutioiden keskinäisestä toiminnasta. Molemmissa valtioissa monarkia, h…
