Exploring message themes in antismoking advertising targeted at teenagers
2008
PurposePrevious studies have indicated that antismoking advertising potentially prevents or reduces smoking among teenagers. However, not all message themes of antismoking advertising have proved effective. This study aims to explore the effects of different message themes on teenagers' intention to smoke. Attitude towards the advertisement and attitude towards the act (smoking) are proposed as mediating variables between the message theme and smoking intentions. The paper also aims to examine effect of three themes, namely health effects, mental effects and social effects on smoking/not smoking.Design/methodology/approachThe data consist of 325 Finnish high school students aged between 13 …
Carta abierta a la comunidad educativa: ni boicot ni silencio
2002
El seis de abril de 2002, más de un centenar de catedráticos europeos, princi- palmente del Reino Unido, publicaron en The Guardian un llamamiento para una moratoria de todos los vínculos académicos y culturales con Israel, en tanto el Gobierno Israelí no cumpla las resoluciones de Naciones Unidas y abra negociaciones serias de paz con la Autoridad Palestina. Un llamamiento similar tuvo lugar también en los Estados Unidos.
Esposizione a campi elettromagnetici a bassa frequenza (ELF) in ambito occupazionale e nella popolazione generale
2011
Scopo del presente lavoro è quello di verificare l’eventuale riscontro di alterazioni della frequenza cardiaca e del ritmo cardiaco in un campione di soggetti esposti professionalmente a campi elettromagnetici, nello specifico lavoratori di centrali elettriche e sottostazioni, afferenti presso l’ambulatorio di cardiologia della Sezione di MDL dell’AOUP di PA, posti a confronto con soggetti di pari età e sesso non esposti al fattore di rischio considerato. I dati raccolti sono stati messi in relazione ai rilievi ambientali dei campi elettromagnetici a bassa frequenza effettuati dall’ARPA Sicilia (1). Sono stati quindi analizzati i risultati ottenuti nelle due popolazioni in esame al fine di …
Prenatal exposure to mixtures of xenoestrogens and repetitive element DNA methylation changes in human placenta
2014
BACKGROUND: Prenatal exposure to endocrine disrupting compounds (EDCs) has previously shown to alter epigenetic marks. OBJECTIVES: In this work we explore whether prenatal exposure to mixtures of xenoestrogens has the potential to alter the placenta epigenome, by studying DNA methylation in retrotransposons as a surrogate of global DNA methylation. METHODS: The biomarker total effective xenoestrogen burden (TEXB) was measured in 192 placentas from participants in the longitudinal INMA Project. DNA methylation was quantitatively assessed by bisulfite pyrosequencing on 10 different retrotransposons including 3 different long interspersed nuclear elements (LINEs), 4 short interspersed nuclear …
Fate of endocrine disruptor compounds in an anaerobic membrane bioreactor (AnMBR) coupled to an activated sludge reactor
2018
[EN] The occurrence and fate of three groups of micropollutants - alkylphenols, pentachlorophenol and hormones - were studied in a pilot plant consisting of an anaerobic membrane bioreactor (AnMBR) coupled to an activated sludge reactor (University of Cape Town configuration - UCT). Under anaerobic conditions, the octylphenol and technical-nonylphenol soluble concentrations increased producing negative degradation ratios (i.e., -175 and -118%, respectively). However, high 4-n-nonylphenol and bisphenol-A degradation ratios (92 and 59% for 4-n-nonylphenol and bisphenol-A, respectively) as well as complete pentachlorophenol, estrone, 17 beta-estradiol and 17 alpha-ethinylestradiol removal were…
Removal and fate of endocrine disruptors chemicals under lab-scalepostreatment stage. Removal assessment using light, oxygen and microalgae
2013
[EN] The aim of this study was to assess the effect of light, oxygen and microalgae on micropollutants removal. The studied micropollutants were 4-(1,1,3,3-tetramethylbutyl)phenol (OP), technical-nonylphenol (t-NP), 4-n-nonylphenol (4-NP), Bisphenol-A (BPA). In order to study the effect of the three variables on the micropollutants removal, a factorial design was developed. The experiments were carried out in four batch reactors which treated the effluent of an anaerobic membrane bioreactor. The gas chromatography mass spectrometry was used for the measurement of the micropollutants. The results showed that light, oxygen and microalgae affected differently to the degradation ratios of each …
Simulated solar UV-irradiation of endocrine disrupting chemical octylphenol.
2009
The photolysis of octylphenol (OP) was investigated using a solar simulator in the absence/presence of dissolved natural organic matter (DNOM), HCO(3)(-), NO(3)(-) and Fe(III) ions. The effects of different parameters such as initial pH, initial concentration of substrate, temperature, and the effect of hydrogen peroxide concentration on photodegradation of octylphenol in aqueous solution have been assessed. The results indicate that the oxidation rate increases in the presence of H(2)O(2), nitrate and DNOM. Phenol, 1,4-dihydroxylbenzene and 1,4-benzoquinone were identified as intermediate products of photodegradation of octylphenol, through an HPLC method. In addition, the disappearance of…
Media for the minorities: Russian language media in Estonia 1990–2012
2013
This article aims to explore the ways in which Estonian public broadcasting tackles one specific media service sphere; how television programmes for language minorities are created in a small country, how economics and European Union media policy have influenced this processes. The article highlights major tensions, namely between Estonian and Russian media outlets, Estonian and Russian speakers within Estonia and the EU and Estonia concerning the role of public service broadcasting (PSB). For research McQuail’s (2010) theoretical framework of media institutions’ influencers – politics, technology and economics – is used. For analyses media regulatory acts and audience surveys are accomplis…
Paedeia café nuorten opettajien silmin: käsityksiä opettajaopiskelijoiden ja opettajien yhteisestä vertaisryhmämentoroinnista
2016
Hakari, Henni & Mantere Viivi. 2016. Paedeia Café nuorten opettajien silmin – käsityksiä opettajaopiskelijoiden ja opettajien yhteisestä vertaisryhmämentoroinnista. Kasvatustieteen pro gradu -tutkielma. Jyväskylän yliopisto. Opettajankoulutuslaitos. 68 sivua. Paedeia Cafe on uusi vertaisryhmämentoroinnin muoto ja osa Euroopassa toteutettavaa PAEDEIA-hanketta. Paedeia Cafén tavoitteena on tuoda opettajankoulutus ja työelämä lähemmäksi toisiaan ja näin tarjota tukea opettajille työuran alkuvaiheeseen. Tutkimuskohteena oli Paedeia Café -ryhmiin osallistuvat nuoret opettajat. Tutkimuksen tarkoituksena oli selvittää, millaisia käsityksiä näillä nuorilla opettajilla on ryhmän toiminnasta ja milla…
Disrupting Industries With Blockchain: The Industry, Venture Capital Funding, and Regional Distribution of Blockchain Ventures
2016
The blockchain (i.e., a decentralized and encrypted digital ledger) has the potential to disrupt many traditional business models. This study investigates the emerging blockchain business-application landscape by analyzing its industry, venture capital funding, and regional distribution. We do so by matching four venture databases on blockchain-based startups. First, our results show that blockchain startups are most prominently represented in the Finance & Insurance and Information & Communication industries. A fine-grained analysis of financial services yields increasing novel applications in existing service offerings – especially in payment networks and processing. Second, consistent wi…
