Minority youth and social transformation in Australia: Identities, belonging and cultural capital

© 2014 by the authors; licensee Cogitatio (Lisbon, Portugal). Increasingly minority youth, especially from Muslim backgrounds, have been seen in Australian public policy and the media as potentially disruptive and transgressive. In some European societies similar young people have been portrayed as living in parallel and disconnected social spaces, self-segregated from interaction with the wider community. Yet Australian ethnic minority youth do not fulfil either of these stereotypes. Rather, despite their often regular experiences of racism or discrimination, they continue to assert a strong identification with and belonging to Australian society, albeit the society that marginalizes and denigrates their cultural capital. In particular it is the neighbourhood and the locality that provides the bridge between their home cultures and the broader world, contributing to a range of positive aspirations and fluid identities

Introduction : media and illiberal democracy in Central and Eastern Europe

This introductory overview opens the series of articles included in the issue entitled Media and Illiberal Democracy in Central and Eastern Europe, and sets the scene for the debate on the relationship between illiberal trends in politics and media landscapes in the region. Drawing on existing scholarship, it traces the roots and the evolution of illiberalism, focusing the discussion within the confines of particularities of media landscapes. Through the introduction of articles addressing manifestations of illiberalism in media landscapes, it argues that “illiberal turn” in Central and Eastern Europe is part of a global political shift, rather than a regional one

The politics of playing along: radio and regulation in democratic Europe

The loss of localism has been a common trend in most radio markets in Europe and the United States. Deregulation of ownership led to a concentration phenomenon that has affected local radios in several western democracies. New forms of regulation have been considered as possible ways to stop the erosion of localism by applying rules to markets in the defense of diversity, pluralism, and the local dimension. This article analyses the local radio market in Portugal, by assessing the changes in the legislation and by examining the regulatory action that can, according to its remit, act preventively to avoid market forces to harm these principles.info:eu-repo/semantics/publishedVersio

Poland's 2011 Online Election Campaign: New Tools, New Professionalism, New Ways to Win Votes

This article analyzes the use of the online environment within the context of the Polish parliamentary election of 2011. Using traditional methods of content analysis, we find that parties tend to adhere to a professionalized model of campaigning, and adapting online tools to suit the objectives of the campaign. There also appears to be a recognition that their most likely visitors to these online presences would be converts, and so they attempt to mobilize supporters rather than convert browsers. New parties and candidates are more likely to target browsers, with the latter offering a more personalized experience to online visitors. Importantly, when analyzing the outcome of the contest, we find that being online matters for candidates when controlling for all other variables. Equally, the reach the candidate has, which may well influence their vote share, is dependent on offering a more personalized, representational image and having a frequently updated online presence that should encourage repeat visits. Cumulatively, we suggest the future of online campaigning must not only focus on having a presence, but on using it in a way that appeals to a range of visitors, encouraging repeat visits, and that this strategy could have a positive impact on election outcomes. © Taylor & Francis Group, LLC

Induction of cancer-specific cytotoxicity towards human prostate and skin cells using quercetin and ultrasound

Bioflavonoids, such as quercetin, have recently emerged as a new class of chemotherapeutic drugs for the treatment of various cancer types, but are marred by their low potency and poor selectivity. We report that a short application of low-frequency ultrasound selectively sensitises prostate and skin cancer cells against quercetin. Pretreatment of cells with ultrasound (20 kHz, 2 W cm−2, 60 s) selectively induced cytotoxicity in skin and prostate cancer cells, while having minimal effect on corresponding normal cell lines. About 90% of the viable skin cancer cell population was lost within 48 h after ultrasound-quercetin (50 μM) treatment. Ultrasound reduced the LC50 of quercetin for skin cancer cells by almost 80-fold, while showing no effect on LC50 for nonmalignant skin cells

Corrosion behaviour of porous Ti intended for biomedical applications

Porous Ti implants are being developed inorder to reduce the biomechanical mismatch between theimplant and the bone, as well as increasing the osseointegrationby improving the bone in-growth. Most of the focusin the literature has been on the structural, biological andmechanical characterization of porous Ti whereas there islimited information on the electrochemical characterization.Therefore, the present work aims to study the corrosionbehaviour of porous Ti having 30 and 50 % ofnominal porosity, produced by powder metallurgy routeusing the space holder technique. The percentage, size anddistribution of the pores were determined by image analysis.Electrochemical tests consisting of potentiodynamicpolarization and electrochemical impedance spectroscopywere performed in 9 g/L NaCl solution at body temperature.Electrochemical studies revealed that samples presenteda less stable oxide film at increased porosity, morespecifically, the complex geometry and the interconnectivityof the pores resulted in formation of less protectiveoxide film in the pores.This study was supported by FCT with the reference project UID/EEA/04436/2013, by FEDER funds through the COMPETE 2020 – Programa Operacional Competitividade e Internacionalizac¸a˜o (POCI) with the reference project POCI-01-0145- FEDER-006941, Programa de Acc¸o˜es Universita´rias Integradas LusoFrancesas’ (PAUILF TC-12_14), and The Calouste Gulbenkian Foundation through ‘‘Programa de Mobilidade Acade´mica para Professores’’.
