Bank fragility and contagion: Evidence from the bank CDS market
2016
Understanding how contagion works among financial institutions is a top priority for regulators and policy makers who aim to foster financial stability and to prevent financial crises. Using bank credit default swap (CDS) data, we provide a framework for the evaluation of contagion among banks in different countries and regions during a period of prolonged financial distress. We measure contagion in terms of return spillovers, following a Generalized VAR (GVAR) approach. In addition, we propose an innovative framework to distinguish between two types of contagion: systematic (linked to global factors), and idiosyncratic (linked to bank specific factors). We find evidence of both types of co…
Maccannell en perspectiva: análisis crítico sobre la obra el turista
2010
A obra de Dean MacCannell representou uma grande contribuição aos estudos do turismo, a partir da década de 1960, por aportar conceitos na época inovadores sobre o tema da autenticidade da experiência turística. O artigo critica a obra deste sociólogo, não mediante um contraste com a evidência empírica mas indo diretamente ao núcleo teórico, buscando antecedentes na sociologia francesa e na etnometodologia estadounidense.
Alcohol consumption and hormonal alterations related to muscle hypertrophy: a review
2014
Detrimental effects of acute and chronic alcohol (ethanol) consumption on human physiology are well documented in the literature. These adversely influence neural, metabolic, cardiovascular, and thermoregulatory functions. However, the side effects of ethanol consumption on hormonal fluctuations and subsequent related skeletal muscle alterations have received less attention and as such are not entirely understood. The focus of this review is to identify the side effects of ethanol consumption on the major hormones related to muscle metabolism and clarify how the hormonal profiles are altered by such consumption.
Examining Consumer-Brand Relationships in the UK Energy Sector A Social Media Perspective
2018
With social media transforming how customers interact with brands, this study explores the consumer –brand relationship in UK energy sector which has a reputation for lack of trust by customers. Using user-generated contents on Facebook pages of the ‘big six’ UK energy companies, the study qualitatively operationalised and applied three consumer-brand relationships construct, exploring the interplay between the brands and the consumer. Findings revealed various indications of brand trust, satisfaction and affiliation but overall customers are not satisfied with their relationship with energy companies, they want to know there is a brand on their side, who takes an interest in their complain…
Identification of Defensive Performance Factors in the 2010 FIFA World Cup South Africa
2016
The aim of this study was to determine the efficacy of defensive play in elite football, to identify variables associated with the direct recovery of ball possession, and to propose a model for predicting the success of defensive transitions. We analyzed 804 transitions in the final stages of the Fedération Internationale Football Association (FIFA) World Cup 2010, and investigated the following variables using univariate, bivariate, and multivariate analyses: duration of defensive transition, possession loss zone, position of players at the start and end of the defensive transitions, defensive organization, general defensive approach, time of the match, position of defense, zone in which t…
Self-efficacy and performance of the roundhouse kick in taekwondo
2014
[ES] El desarrollo de escalas de autoeficacia permite el análisis de las percepciones de los deportistas y el examen de la relación entre dichas percepciones y el rendimiento. El objetivo de este estudio fue (1) desarrollar una escala específica de autoeficacia para una tarea de taekwondo, la patada circular, y (2) analizar el rendimiento deportivo y su relación con los resultados de dos escalas de autoeficacia (específica y general) en función del género de los deportistas. En el estudio participaron 43 taekwondistas (33 hombres y 10 mujeres). Se administraron las escalas de autoeficacia Física (PSE) y Específica (RKSES). Los datos de rendimiento (fuerza de impacto y tiempo total de respue…
"Hei mitä tää ny tarkottaa?" : experiences of intercultural communication and linguistic shock while using English abroad
2016
Globalisaation ja kansainvälistymisen myötä korkeakouluopiskelijoiden kansainvälinen liikkuvuus on lisääntynyt huomattavasti. Ulkomailla oleskelu on tarjonnut monille hyvinkin positiivisia kokemuksia, mutta uudessa kulttuurissa eri kielellä toimiminen voi aiheuttaa myös yllättäviä ongelmatilanteita. Tutkimuksen teoriataustan aloittaa katsaus kansainväliseen opiskelijaliikkuvuuteen, jonka jälkeen esitellään muutamia tärkeimpiä kulttuurienvälisen viestinnän teorioita. Kulttuurienvälinen viestintäkompetenssi on myös olennainen tässä tutkimuksessa, joten myös siitä keskustellaan. Kielishokki ilmiönä esitellään aluksi sekä kulttuurisesta että kielellisestä näkökulmasta, jonka jälkeen tarkastella…

Superdiversity perspective and the sociolinguistics of social media
2018
This chapter shows how the superdiversity perspective suggested in recent critical sociolinguistics provides the study of social media discourse and communication with a useful approach to conceptualizing and empirically investigating complex and multiple axes of diversity and difference in social media practices. It discusses recent work in sociolinguistics of social media, highlighting how social media practices illustrate many of the aspects of contemporary social life and communication that are considered symptomatic of superdiversity. It shows how research in this field has moved from viewing superdiversity as a quality or quantity characterizing specific places, spaces, groups and net…
Comparing analytical methods to detect SARS-CoV-2 in wastewater
2021
Wastewater based epidemiology (WBE) has emerged as a reliable strategy to assess the coronavirus disease 2019 (COVID-19) pandemic. Recent publications suggest that SARS-CoV-2 detection in wastewater is technically feasible; however, many different protocols are available and most of the methods applied have not been properly validated. To this end, different procedures to concentrate and extract inactivated SARS-CoV-2 and surrogates were initially evaluated. Urban wastewater seeded with gamma-irradiated SARS-CoV-2, porcine epidemic diarrhea virus (PEDV), and mengovirus (MgV) was used to test the concentration efficiency of an aluminum-based adsorption-precipitation method and a polyethylene…
