Three studies were conducted to investigate how social media affordances influence individuals’ source credibility perceptions in risk situations. The MAIN model (Sundar, 2008), warranting theory (Walther & Parks, 2002), and signaling theory (Donath, 1999) served as the theoretical framework to examine the effects of bandwagon cues and identity cues embedded in retweets and users’ profile pages for health and risk online information processing. Study One examines whether bandwagon heuristics triggered by retweets would influence individuals’ source credibility judgments. Study Two investigates how bandwagon heuristics interact with different identity heuristics in credibility heuristics on an individual level. Study Three explores bandwagon heuristics at the organizational level. Three post-test only experiments with self-report online surveys were conducted to investigate the hypothesis and research questions. Results indicate that different online heuristic cues impact the judgments of competence, goodwill, and trustworthiness at different levels. Authority strongly influenced source credibility perceptions. A reverse-bandwagon effect was observed in influencing source credibility judgments. Theoretical and practical implications are discussed.

Selected aspects of occupational safety and health protection Abstract This thesis focuses on legal regulation of selected aspects of occupational safety and health (OSH) protection in the context of Czech law. This is a classical area of labour law whose importance grows together with the growing complexity of working practices. The aim of the thesis is to provide a description of the current regulation and subsequently to analyse selected aspects related to the educational sector. The thesis is, apart from introduction and conclusion, divided into six chapters. In the first chapter, the historical development of OSH is outlined in order to give context to the consecutive chapters. The following chapter provides an overview of the sources of law, since the area of OSH is heavily influenced by the European as well as the international law and the regulation on the national level is considerably fragmented. In the third chapter attention is paid to the rights and obligations of the employer, which are analogous to the fourth chapter, concerning the rights and obligations of the employees (in the field of occupational safety and health). OSH is closely linked to the risk assessment, which is key to successful implementation of OSH standards and greatly helps to reduce occupational injuries and illnesses....

In this scenario, it is evident the need to seek strategies to promote information on risk factors and protection in early childhood. Health education through digital technologies may be a health education strategy. Objective: The objective of this study was to verify the association between wheezing and the food consumption of infants beneficiaries of the Bolsa Família Program (PBF) and to elaborate didactic content of health education to attend this population. Methodology: In order to reach the research objective, it was necessary to present the methodology in two components (1), a cross-sectional study carried out with children under 180 days, beneficiaries of the Bolsa Família Program, during compulsory annual weighings. A standardized questionnaire was used in the International Study of Infant Wheezing (EILS) and the questions of the Food Consumption Markers were included. Statistical analyzes were performed in the software Statistical Package for Social Science (SPSS), version 18.0., Considering the level of significance of 5% (p <0.05). (2) Study with descriptive, quantitative design. The didactic content was elaborated with the help of a pedagogical team and a technical team which was evaluated by health professionals of the area (nurses, nutritionists, physicians and physiotherapists), which will be available in the virtual learning space MAIS Unifra , of the Franciscan University Center. The chi-square test and the prevalence ratio with 95% confidence interval were used to analyze the data, and the significance level adopted was 5%. Results: (1) 47 infants were evaluated. Of these, 24 (51.1%) were males, with a mean age of 123.49 ± 55.54 days. Regarding EILS, 26 (55.3%) infants had relatives with asthma and 23 (50%) had wheezing in the last six months. It was observed that 5 (100%) infants who did not receive breast milk presented wheezing in the last six months (RP-2,7- 95% CI: 1.61-3.21), (p = 0.018), 14 (40 (p = 0.016) and 15 (41.71%) ingested salt meal (RP-5.6- 95% CI-1) , 03-30.2), (p = 0.032). Breast milk was the consumption variable that presented the highest number of associations statistically significant with the ISLS questions. Product: (2) The didactic content "RISK FACTORS AND PROTECTION FOR CHILDREN IN CHILDREN", were sent to 41 health professionals, of which 20 responded, of which 17 (85%) were female and 3 (15 %) of males, with mean age of 35.95 ± 10.56 years. Among the professionals who answered the questionnaires 7 (35%) nurses; 7 (35%) nutritionists; 3 (15%) physicians and 3 (15%) physiotherapists. 18 (90%) of these considered as very relevant in addressing content, 13 (65%) evaluated very relevant didactic content, and answered the proposed objectives (95%) yes. And 17 (85%) considered the language appropriate and content complete. Conclusion: Children who did not receive breast milk had a prevalence ratio of approximately three times that of wheezing, and this value doubled when fruits and / or salt food were ingested early. Therefore, in this proposal, the use of new technologies was explored, envisaging a different approach to address the risk factors and protection for wheezing / Introdução: O consumo alimentar infantil e a nutrição de uma criança constituem-se como fatores determinantes e condicionantes para a sua saúde, visto que o consumo alimentar saudável é um fator positivo para o não desenvolvimento de doenças respiratórias e a sibilância, aumentando a qualidade do estado nutricional que está relacionado à saúde em todas as fases do desenvolvimento da vida. Neste cenário, evidencia-se a necessidade de buscar estratégias para promover informações sobre os fatores de risco e proteção na primeira infância. Educação em saúde por meio de tecnologias digitais pode ser uma estratégia de educação em saúde. Objetivo: O objetivo deste estudo foi verificar a associação entre a sibilância e o consumo alimentar de lactentes beneficiários do Programa Bolsa Família (PBF) e elaborar conteúdo didático tecnológico de educação em saúde para atender esta população. Metodologia: Para atingir o objetivo da pesquisa, foi necessário apresentar a metodologia em dois componentes (1) trata-se de uma pesquisa de delineamento transversal realizada com crianças menores de 180 dias, beneficiárias do Programa Bolsa Família, durante as pesagens anuais obrigatórias. Utilizou-se um questionário padronizado Estudo Internacional de Sibilância em Lactentes (EILS) e incluíram-se as questões dos Marcadores de Consumo Alimentar. As análises estatísticas foram realizadas no software Statistical Package for Social Science (SPSS), versão 18.0., considerando o nível de significância de 5% (p<0,05). (2) Estudo com delineamento descritivo, quantitativo. Realizou-se a elaboração do conteúdo didático com o auxílio de uma equipe pedagógica e uma equipe técnica o qual passou por avaliação de profissionais de saúde da área (enfermeiros, nutricionistas, médicos e fisioterapeutas) o qual será disponibilizado no espaço virtual de aprendizagem MAIS Unifra, do Centro Universitário Franciscano. Para análise dos dados utilizou-se o teste qui-quadrado e a razão de prevalência com intervalo de confiança de 95%, e o nível de significância adotado foi de 5%. Resultados: (1) avaliaram-se 47 lactentes. Destes, 24(51,1%) eram do sexo masculino, com idade média de 123,49±55,54 dias. Quanto ao EILS, 26(55,3%) lactentes têm familiares com asma e 23(50%) apresentaram sibilância nos últimos seis meses. Observou-se que 5(100%) lactentes que não receberam leite do peito apresentaram sibilância nos últimos seis meses (RP-2,7- IC95%:1,61-3,21), (p=0,018), 14(40%) ingeriram frutas (RP-6,75- IC95%: 1,26-36,02), (p=0,016) e 15(41,71%) ingeriram comida de sal (RP-5,6- IC95% 1,03-30,2), (p=0,032). O leite do peito foi a variável de consumo que apresentou maior número de associações estatisticamente significativas com as questões do EISL. Produto: (2) O conteúdo didático “FATORES DE RISCO E PROTEÇÃO PARA O CHIADO EM CRIANÇAS”, foram enviados para 41 profissionais da área da saúde, destes 20 responderam, dos quais 17(85%), do sexo feminino e 3(15%) do sexo masculino, com média de idade de 35,95±10,56 anos. Entre os profissionais que responderam os questionários 7(35%) enfermeiros; 7(35%) nutricionistas; 3(15%) médicos e 3(15%) fisioterapeutas. 18(90%) destes consideraram como muito relevante em abordar o conteúdo, 13(65%) avaliaram o conteúdo didático muito relevante, e se respondia aos objetivos propostos (95%) sim. E 17(85%) consideraram a linguagem adequada e conteúdo completo. Conclusão: Crianças que não receberam leite do peito tiveram uma razão de prevalência de aproximadamente três vezes de apresentar sibilância, sendo que este valor dobrou quando houve a ingestão de frutas e/ou de comida de sal precocemente. Portanto, nesta proposta, explorou-se o uso de novas tecnologias, vislumbrando um enfoque diferenciado para abordar os fatores de risco e proteção para a sibilância.

<p>Gojaznost i fizička neaktivnost su među najznačajnijim faktorima rizika za hronične nezarazne bolesti, koje su vodeći javnozdravstveni problemi u svetu i kod nas. Cilj istraživanja je procena prevalencija gojaznosti, predgojaznosti i fizičke neaktivnosti u slobodno vreme kod odraslog stanovni&scaron;tva Vojvodine, kao i procena povezanosti demografskih, socio-ekonomskih i bihevioralnih faktora sa gojazno&scaron;ću i fizičkom neaktivno&scaron;ću u slobodno vreme. Istraživanje predstavlja deo Istraživanja zdravlja stanovni&scaron;tva Srbije iz 2013. godine koje je sprovedeno od strane Ministarstva zdravlja Republike Srbije, kao studija preseka na reprezentativnom stratifikovanom dvoetapnom uzorku. Istraživanjem je obuhvaćeno 3337 osoba uzrasta 20 i vi&scaron;e godina sa prebivali&scaron;tem u Vojvodini. Instrument istraživanja su bili upitnici konstruisani u skladu sa upitnikom Evropskog istraživanja zdravlja, a podaci o telesnoj masi i telesnoj visini su dobijeni merenjem. Rezultati istraživanja su pokazali da je u 2013. godini svaka četvrta odrasla osoba u Vojvodini bila gojazna, a svaka treća osoba predgojazna. U odnosu na 2000. godinu nije do&scaron;lo do značajnog povećanja prevalencija gojaznosti i predgojaznosti, mada su se prevalencije održale na visokom nivou. &Scaron;anse za gojaznost su rasle do 75-te godine života, a nakon toga opadaju. Najveću &scaron;ansu za gojaznost su imale osobe u braku ili vanbračnoj zajednici. Gojaznost je povezana sa socio-ekonomskim karakteristikama samo kod žena. Značajni prediktori gojaznosti kod žena su bili najniži nivo obrazovanja, lo&scaron; materijalni status i nezaposlenost/ekonomska neaktivnost. Biv&scaron;i pu&scaron;ači su imali oko dva puta veću &scaron;ansu za gojaznost u odnosu na pu&scaron;ače, dok je &scaron;ansa za gojaznost bila manja kod osoba koje su u poslednjih 12 meseci konzumirale alkohol. Fizička neaktivnost u slobodno vreme, kao i fizička neaktivnost u domenu transporta povećavaju verovatnoću za pojavu gojaznosti. Prevalencija fizičke neaktivnosti u slobodno vreme je bila veoma visoka (89%). &Scaron;anse za fizičku neaktivnost u slobodno vreme su se značajno povećavale sa staro&scaron;ću. Prediktori fizičke neaktivnosti su bili ženski pol, život u braku/vanbračnoj zajednici, nizak nivo obrazovanja i lo&scaron; materijalni status. Pu&scaron;ači su imali oko dva puta veću &scaron;ansu da budu fizički neaktivni u odnosu na nepu&scaron;ače, dok je stanovni&scaron;tvo koje je konzumiralo alkohol imalo manju &scaron;ansu da bude fizički neaktivno u slobodno vreme. Gojazne osobe, kao i fizički neaktivne osobe su lo&scaron;ije ocenjivale svoje zdravlje. Gojazne osobe (bez obzira na nivo fizičke aktivnosti) su imale oko 3,5 puta veću &scaron;ansu za pojavu multimorbiditeta u odnosu na osobe sa optimalnom telesnom masom koje su fizički aktivne u slobodno vreme. Gojazne osobe su imale četiri puta veću &scaron;ansu za arterijsku hipertenziju i skoro četiri puta veću &scaron;ansu za dijabetes u odnosu na normalno uhranjene osobe. Gojaznost i fizička neaktivnost u slobodno vreme su značajni javnozdravstveni problemi kod odraslog stanovni&scaron;tva u Vojvodini na &scaron;ta ukazuju visoke prevalencije, velika zastupljenost među vulnerabilnim kategorijama stanovni&scaron;tva, nejednakost u frekvenciji između različitih socio-ekonomskih kategorija stanovni&scaron;tva, preventabilnost, povezanost sa lo&scaron;ijom samoprocenom zdravlja i hroničnim bolestima.</p> / <p>Obesity and physical inactivity are one of the most significant risk factors for chronic noncommunicable diseases, which are one of the most important public health problems in the world and also in our country. The aim of the study was to evaluate the prevalence of obesity and leisure time physical inactivity among the adult population of Vojvodina, and also to evaluate the association of demographic, socio-economic and behavioral factors with obesity and leisure time physical inactivity. The study is part of the National Health Survey of Serbia, a cross-sectional study conducted in year 2013 by the Ministry of Health of Republic of Serbia on a representative stratified two-stage sample. The study included 3337 participants aged 20 and over who resided in Vojvodina. The instruments were questionnaires designed in line with the European Health Interview Survey questionnaire, and data on body mass and body height were measured. Results showed that in year 2013 every fourth adult person in Vojvodina was obese, and every third overweight. There was no increase in prevalences compared to year 2000, although they remained high. Odds of obesity increased until age 75, and afterwards decreased. The highest odds of obesity were among persons who were married or living with a partner. Obesity was associated with socio-economic factors only among women. The predictors of obesity among women were: low level of education, low wealth index and unemployment/economical inactivity. Former smokers had two times higher odds of obesity, compared to smokers, while persons who consumed alcohol in the last 12 months had lower odds to be obese. Leisure time physical inactivity, as well as transport related physical inactivity were important predictors of obesity. Prevalence of leisure time physical inactivity was very high (89%). With increasing age, odds of physical inactivity increased. Predictors of physical inactivity were female gender, being married or living with a partner, low level of education and low wealth index. Smokers had two times higher odds of physical inactivity in comparison to nonsmokers, while persons who consumed alcohol in the last 12 months had lower odds of physical inactivity. Obese and physically inactive persons were more likely to assess their health as average, poor or very poor. Obese persons (regardless of the level of physical activity) had three and a half times higher odds of multimorbidity compared to persons with healthy weight who were physically active. Obese persons had four times higher odds of arterial hypertension and almost four times higher odds of diabetes. Obesity and physical inactivity are important public health problems among the adult population in Vojvodina due to high prevalences in population, especially among vulnerable groups, inequality in frequency among different socio-economic groups, preventability and association with poor health perception and chronic diseases.</p>
