Increased consumption of fruit and vegetables is related to a reduced risk of coronary heart disease: meta-analysis of cohort studies

Increased consumption of fruit and vegetables has been shown to be associated with a reduced risk of coronary heart disease (CHD) in many epidemiological studies, however, the extent of the association is uncertain. We quantitatively assessed the relation between fruit and vegetable intake and incidence of CHD by carrying out a meta-analysis of cohort studies. Studies were included if they reported relative risks (RRs) and corresponding 95% confidence interval (CI) of CHD with respect to frequency of fruit and vegetable intake. Twelve studies, consisting of 13 independent cohorts, met the inclusion criteria. There were 278 459 individuals (9143 CHD events) with a median follow-up of 11 years. Compared with individuals who had less than 3 servings/day of fruit and vegetables, the pooled RR of CHD was 0.93 (95% CI: 0.86–1.00, P=0.06) for those with 3–5 servings/day and 0.83 (0.77–0.89, P<0.0001) for those with more than 5 servings/day. Subgroup analyses showed that both fruits and vegetables had a significant protective effect on CHD. Our meta-analysis of prospective cohort studies demonstrates that increased consumption of fruit and vegetables from less than 3 to more than 5 servings/day is related to a 17% reduction in CHD risk, whereas increased intake to 3–5 servings/day is associated with a smaller and borderline significant reduction in CHD risk. These results provide strong support for the recommendations to consume more than 5 servings/day of fruit and vegetables.

The effects of time pressure and experience on nurses' risk assessment decisions : a signal detection analysis

Background: Time pressure and, occasionally, suboptimal assessment decisions are features of nursing in acute care.

Objectives: To explore the effect of generic and specialist clinical experience on the ability to detect the need to take action in acute care and the impact of time pressure on nurses' decision-making performance.

Methods: Experienced acute care registered nurses (n = 241) were presented with 50 vignettes of real clinical risk assessments. Each vignette contained seven information cues. In response to these vignettes, nurses had to decide whether to intervene or not. The 26 vignettes were time limited and mixed randomly into the 50 cases. Signal detection analysis was used to establish nurses' performance, personal decision thresholds ([beta]), and their abilities (d') to distinguish a signal of clinical risk from the clinical noise of noncontributory information.

Results: Nurses had significantly lower d' and were significantly less likely to indicate intervening under time pressure. For ability-but not threshold-there was a significant interaction of time pressure and years of experience in acute care. With no time pressure, d' increased in line with years of experience. Under time pressure, there was no effect.

Discussion: Time pressure reduced nurses' ability to detect the need and the tendency to report intervening. Thus, there were more failures to report appropriate intervention under time pressure, and the positive effects of clinical experience were negated under time pressure. More and larger scale research on the effect on clinical outcomes of time pressured nursing choices is required.

Exploring marketing to marketers : a content analysis of advertisements in marketing news over 15 years

This paper explores advertising to marketers within Marketing News over four periods 1992, 1997, 2002 and 2007. The results identified the types of advertisements, in terms of appeal; products (most of which were for marketing research related activates) and coverage were relatively stable over time. There were increases in the number of advertisements, the appearance of web related services and a slight increase in products with a global focus and a reduction of a regional focus were evident.

How to write an unsuccessful entrepreneurial business plan : content analysis of the normative literature reveals a flawed paradigm

The study's aim was to investigate whether an Entrepreneurial Business Planning (EBP) paradigm could be discovered as a body of core, common maxims within the normative EBP literature (works of the 'how-to-write-a-successful-new-venture-business-plan' genre). It employed content analysis techniques adapted mainly from the methodological prescriptions of Krippendorf (1980) and Carney (1972). The textual investigation produced a comprehensive, quantitative data base capable of sufficient interpretative richness to discover that an established Entrepreneurial Business Planning paradigm does exist. Its major elements embrace two key assumptions, four strong mandates and four weaker mandates.

The discovery is significant for two main reasons. First, it provides a formally-researched, explicitly-articulated EBP paradigm. This can replace the anecdotal, unarticulated assumption (implicit in most of the normative EBP literature) that an EBP paradigm 'probably exists'. Second, the research redresses some of the imbalance between entrepreneurship teaching- where Entrepreneurial Business Planning is at the core of international curricula - and entrepreneurship research which has virtually ignored EBP as a topic worthy of serious scrutiny. A firm basis for critical, scholarly exploration of the neglected EBP field is now established. This takes the theory and practice of EBP into a new era beginning with recognition that the discovered EBP paradigm is badly flawed and likely, if blindly applied, to lead to the writing of unsuccessful business plans.

Can qualitative content analysis be adapted for use by social informaticians to study social media discourse? A position paper

IS research on social media (e.g. Facebook, Twitter, blogs) has so far used user surveys or quantitative content analysis (QuantCA) research methods almost exclusively. There is considerable potential for social informatics research to use qualitative content analysis (QualCA) to explore social media discourse and its appropriation by people “in situ”. This paper presents the position that QualCA offers researchers the flexibility to identify emergent research questions and units of analysis which they may not have preconceived. This is likely to be important for IS research because of the infancy and evolving nature of social media discourse. The paper puts forward suggestions on how the QualCA research method can be adapted for this type of research.

Competition and television news in India : a content analysis

In India, not unlike some other developing countries, ruling parties have used public service broadcasters to propagate their virtues, adversely affecting the broadcasters' image as a credible news media. The Indian public service broadcaster. Doordarshan,
which has been besieged by increased competition and government-imposed demandfor selfsufficiency in recent years, continues to struggle to shed its image as a government mouthpiece despite being run by an independent corporation. This article
presents a content analysis of news programs broadcast by Doordarshan and a foreign television network. Star News. The study examines the differences and similarities between Doordarshan and Star TV's prime time news programs broadcast at the turn ofthe century, almost a decade after the advent ofcommercial television in India broke the public service broadcaster's monopoly in the country.

A content analysis of early childhood teachers’ theoretical and practical experiences with infants and toddlers in Australian teacher education programs

 In Australia, the growth in the provision of early childhood services for very young children aged birth to three years has placed increased demands on pre-service teachers as new policy stipulates the need for qualified early childhood teachers. While many teacher education programs offer early childhood courses, they have traditionally had a greater focus on kindergarten and the formal years of schooling. Less is known about the amount of time devoted to developing the specialist educational capacity for teaching and caring for infants and toddlers. This paper explores 55 Australian early childhood teacher undergraduate education programs to provide data regarding what pre-service teachers learn about children from birth to three years of age during their formal program of study. It explores: if pre-service teachers engage in practical experiences with this age range; what content they learn; and how knowledge for this age range is assessed. Utilising information from fully accessible public program websites, data in the form of course details were examined to reveal the extent and nature of courses inclusive of teaching and learning focusing on children aged from birth to three years. Of the 55 programs, 18 programs provided practical experience with infants and toddlers, and to a lesser extent content was evident and assessed. Most of the programs which included a focus on birth to three years of age were delivered by Victorian institutions. Findings are important for the future of early childhood teacher education in Australia and hold key messages for teacher registration bodies.

Food references and marketing in popular magazines for children and adolescents in New Zealand. A content analysis

Food marketing is recognized as an important factor influencing children's food preferences and consumption. The purpose of this study was to examine the nature and extent of unhealthy food marketing and non-branded food references in magazines targeted at and popular among children and adolescents 10–17 years in New Zealand. A content analysis was conducted of all food references (branded and non-branded) found in the five magazines with the highest readership among 10–17 year olds, and the three magazines (of which two were already included among the five most popular magazines) targeted to 10–17 year olds. For each of the six magazines one issue per month (n = 72 issues in total) over a one-year period (December 2012–January 2014) was included. All foods referenced were classified into healthy/unhealthy according to the food-based Ministry of Health classification system. Branded food references (30% of total) were more frequent for unhealthy (43%) compared to healthy (25%) foods. Magazines specifically targeted to children and adolescents contained a significantly higher proportion of unhealthy branded food references (72%, n = 51/71) compared to the most popular magazines among children and adolescents (42%, n = 133/317), of which most were targeted to women. ‘Snack items’ such as chocolates and ice creams were marketed most frequently (n = 104; 36%), while ‘vegetables and fruits’ were marketed the least frequently (n = 9; 3%). Direct advertisements accounted for 27% of branded food references and 25% of those featured health or nutrition claims. Both branded and non-branded food references were common within magazines targeted at and popular among children and adolescents, and skewed toward unhealthy foods. This raises concerns about the effectiveness of self-regulation in marketing and emphasizes that government regulations are needed in order to curb children's current potential high exposures to unhealthy food marketing. In addition, magazine editors could take socially responsible editorial positions in regard to healthy eating.

Corporate social responsibility programs of big food in Australia: a content analysis of industry documents

OBJECTIVE: To examine Corporate Social Responsibility (CSR) tactics by identifying the key characteristics of CSR strategies as described in the corporate documents of selected 'Big Food' companies. METHODS: A mixed methods content analysis was used to analyse the information contained on Australian Big Food company websites. Data sources included company CSR reports and web-based content that related to CSR initiatives employed in Australia. RESULTS: A total of 256 CSR activities were identified across six organisations. Of these, the majority related to the categories of environment (30.5%), responsibility to consumers (25.0%) or community (19.5%). CONCLUSIONS: Big Food companies appear to be using CSR activities to: 1) build brand image through initiatives associated with the environment and responsibility to consumers; 2) target parents and children through community activities; and 3) align themselves with respected organisations and events in an effort to transfer their positive image attributes to their own brands. IMPLICATIONS: Results highlight the type of CSR strategies Big Food companies are employing. These findings serve as a guide to mapping and monitoring CSR as a specific form of marketing.

Auditory processing in children and adolescents in situations of risk and vulnerability

CONTEXTO E OBJETIVO: Crianças e adolescentes que vivem em situação de vulnerabilidade social apresentam uma série de problemas de saúde. Apesar disso, ainda é controversa a afirmação sobre a existência de alterações cognitivas e/ou sensoriais. O objetivo deste estudo foi investigar aspectos relacionados ao processamento auditivo, através da aplicação de testes de potencial evocado auditivo de tronco encefálico (PEATE) e avaliação comportamental do processamento auditivo em crianças em situação de rua, comparando a um grupo controle. TIPO DE ESTUDO E LOCAL: Estudo transversal no Laboratório de Processamento Auditivo, Faculdade de Medicina da Universidade de São Paulo. MÉTODOS: Os testes de processamento auditivo foram aplicados em um grupo de 27 indivíduos, subdivididos em grupos de 11 crianças (7 a 10 anos) e 16 adolescentes (11 a 16 anos) de ambos os sexos, em situação de vulnerabilidade social, e comparado a um grupo controle, formado por 21 crianças, subdivididas em grupos de 10 crianças e 11 adolescentes, pareados por idade, sem queixas. Também se aplicou os PEATE para investigação da integridade da via auditiva. RESULTADOS: Para ambas as faixas etárias, foram encontradas diferenças significantes entre grupos estudo e controle para a maioria dos testes aplicados, sendo que o grupo estudo apresentou desempenho estatisticamente pior do que o controle para todos os testes, exceto para o teste pediatric speech intelligibility. Apenas uma criança apresentou resultado alterado para os PEATE. CONCLUSÕES: Os resultados demonstraram pior desempenho do grupo estudo (crianças e adolescentes) para os testes comportamentais de processamento auditivo, apesar de estes apresentarem integridade da via auditiva em nível de tronco encefálico, demonstrada pela normalidade nos resultados do PEATE.
