(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…

Comparative vs. Transcendental Approaches to Justice: A Misleading Dichotomy in Sen'sThe Idea of Justice

2012

This paper examines the distinction drawn by Amartya Sen between transcendental and comparative theories of justice, and its application to Rawls' doctrine. It then puts forward three arguments. First, it is argued that Sen offers a limited portrayal of Rawls' doctrine. This is the result of a rhetorical strategy that depicts Rawlsian doctrine as more “transcendental” than it really is. Although Sen deploys numerous quotations in support of his interpretation, it is possible to offer a less transcendental interpretation of Rawls. Second, the dichotomy between transcendental and comparative approaches to questions of justice is partly misleading, insofar as any plausible moral doctrine has b…

Sobre los límites de la intervención de los servicios sociales

2018

Uno de los argumentos más comunes a la hora de justificar el exiguo impacto d elos servicios sociales es el escaso peso que éstos representan en el conjunto del gasto social. En el articulo se muestra que esta justificación puede no ser del todo cierta. Pese a que el balance de sus primeros años fue claramente positivo, el análisis de ciertos datos del periodo 1997-2007 previos al estallido de la crisis muestra, a juicio del autor, las crecientes dificultades para mejorar las situaciones de pobreza y exclusión social con independencia de los medios financieros y personales que se hayan dispuesto. Tal afirmación sugiere la posibilidad de que la intervención de los servicios sociales esté som…

Pediatric oncologic endosurgery.

2017

Despite increasing popularity of minimal-invasive techniques in the pediatric population, their use in diagnosis and management of pediatric malignancy is still debated. Moreover, there is limited evidence to clarify this controversy due to low incidence of each individual type of pediatric tumor, huge diversity of the disease entity, heterogeneity of surgical technique, and lack of well-designed studies on pediatric oncologic minimal-invasive surgery. However, a rapid development of medical instruments and technologies accelerated the current trend toward less invasive surgery, including oncologic endosurgery. The aim of this article is to review current literatures about the application o…

Is karate effective in improving postural control?

2012

Background: Performing complex motor skills, such as the ones performed by karate athletes, requires a great sense of balance. Because the posturo-kinetic performance seems to be improved by sport practice, especially by sports involving a lot of posturokinetic activities, the aim of this review was to critically analyse the scientific literature in order to appraise whether any positive correlation between karate and improved postural control is scientifically supported. Material/Methods: The online search engines Scirus and Medline were used for generating the data. A comprehensive literature search was conducted based on the following keywords: “karate”, “postural control” and “body sway…

Methods to determine saddle height in cycling and implications of changes in saddle height in performance and injury risk: A systematic review

2021

The objective of this systematic review was to assess the methods to determine bicycle saddle height and the effects of saddle height on cycling performance and injury risk outcomes. The key motivator of this review was to update and expand the finding reported by a previous narrative review published in 2011. The literature search included all documents from the following databases: Medline, Scopus, CINAHL, OVID and Google Scholar. Studies were screened against the Appraisal tool for Cross-sectional Studies to assess methodological quality and risk of bias. After screening the initial 29,398 articles identified, full-text screening was performed on 66 studies with 41 of these included in t…

Leaps and bounds : towards an integrative theory of cultural evolution

2014

Tutkimuksessa pyritään yhdistämään ajatus kulttuurista eräänlaisen luonnonvalinnan alaisena Dan Sperberin näkemyksien (1) kommunikaation taustadynamiikasta tarkoitet-tujen merkityksien päättelynä niiden kontekstisidonnaisen merkittävyyden perusteella ja (2) erilaisten käsityksien eri kohteista leviämisen suhteen. Tällaisen yhdentävän viiteke-hyksen turvin pyritään vastaamaan pätevästi Sperberin kritiikkiin koskien darwinilaisen luonnonvalinnan soveltamista kulttuurin ilmiöihin. Näihin kritiikkeihin lukeutuvat väitteet, että (1) kulttuurin muutostiheys on liian korkea evoluution tuloksien kasautumisen mahdol-listamiseksi, (2) yleistykset koskien sisältöjä ovat kestämättömiä tehtyjen yliyksin…

DNA extraction from phytoseiid specimens preserved on glass slide

2009

Mites belonging to the family of Phytoseiidae are important biocontrol agents of phytophagous mites (McMurtry and Croft, 1997). But the species used for controlling harmful mites have to be correctly identified. Sometimes using the traditional identification methods it is difficult or uncertain to identify a species especially as various Authors use different characters, very often not stable in the time. In the 60’s M.me Athias-Henriot (Athias-Henriot 1968; 1969) took into consideration the insemination apparatus that is considered a stable character in the time. According to her, the shape of this apparatus could be considered a major criterion for genus distinction; but other scientists …

Redescription of Chiropturopoda nidiphila Wiśniewski & Hirschmann (Acari: Uropodina) from a woodpecker’s tree holes, including all development stages…

2021

All development stages of Chiropturopoda nidiphila Wiśniewski & Hirschmann, 1983 are described, which has previously been known only from the deutonymph stage. The species is closely associated with tree holes excavated by woodpeckers. Chiropturopoda nidiphila was redescribed and the genus diagnosis was completed. The description of the species morphology is based largely on scanning (SEM) electronograms. Diagnoses differentiating all of the known species of the genus Chiropturopoda are provided, including their developmental stages.
