Circulating renin-angiotensin system and catecholamines in childhood: is there a role for birthweight?

There have been only a few reports on the sympathoadrenal and renin-angiotensin systems in children of small gestational age. The purpose of the present study was to investigate plasma levels of ACE (angiotensin-converting enzyme) activity, angiotensin and catecholamines in 8- to 13-year-old children and to determine whether there are correlations between the components of these systems with both birthweight and BP (blood pressure) levels. This clinical study included 66 children (35 boys and 31 girls) in two groups: those born at term with an appropriate birthweight [AGA (appropriate-for-gestational age) group, n = 31] and those born at term but with a small birthweight for gestational age [SGA (small-for-gestational age) group, n = 35]. Concentrations of angiotensin, catecholamines and ACE activity were determined in plasma. Circulating noradrenaline levels were significantly elevated in SGA girls compared with AGA girls (P = 0.036). In addition, angiotensin 11 and ACE activity were higher in SGA boys (P = 0.024 and P = 0.050 respectively). There was a significant association of the circulating levels of both angiotensin 11 and ACE activity with BP levels in our study population. Although the underlying mechanisms that link restricted fetal growth with later cardiovascular events are not fully understood, the findings in the present study support the link between low birthweight and overactivity of both sympathoadrenal and renin-angiotensin systems into later childhood.

Reading That Matters : A Literature Review on Meaningful Reading Experiences in the EFL Classroom

This thesis is a literature review on literature reading in the English as a Foreign Language (EFL) and the English as a Second Language (ESL) classroom, of mainly upper secondary schools. The underlying objective for this work is that meaningful reading experiences can have a positive impact on a developing young individual on his or her way into adulthood. The aim of this thesis is to explore what theories and methods are used when trying to create prerequisites for meaningful reading experiences, and how these experiences actually are realized. Qualitative methods are mainly used, except for a small section of the methodology of finding the sources, which is quantitative in nature. Since very little previous research has been done in the field, the six sources used in this review are internationally spread over five continents. They are mainly analyzed from a theoretical background of reader response and critical literacy perspectives. The main findings show that a number of theoretical approaches and methodologies can be useful in creating meaningful reading experiences. What may have proven most effective was addressing actual problems in the students’ everyday lives through applied critical literacy.

Leisure experiences in tourist attractions : exploring the motivations of local residents

This study was conducted to explore leisure motivations with regard to tourist attractions. A survey of a convenience sample of residents of Melbourne, Australia, was conducted. The sample was then segmented based on the likelihood of visiting a cross-section of Melbourne's tourist attractions in the next 6 months. Analysis using Unger and Kernan's (1983) Subjective Leisure Scale (SLS) was then undertaken to explore whether there were differences across the segments in terms of their leisure motivations. The results highlight that, within this context, intrinsic satisfaction, perceived freedom and arousal emerged as stronger underlying dimensions of motivations to visit tourist attractions, rather than mastery, spontaneity and involvement. This information provides insights for marketers of tourist attractions with regard to what residents are seeking when they visit local tourist attractions. The information can be used to develop more positive experiences at tourist attractions for this important sector of the market.

Environmental management systems auditing:Auditors' experiences in Australia

The last decade of the 20th century witnessed rapid growth in the adoption of various environmental management systems (EMS) within organisations. Environmental consultants and auditors play an intricate role in the  interpretation, implementation and certification of an EMS. This paper presents the experiences of eight leading auditors with respect to the adoption of EMS/ISO 14001 by Australian organisations. The benefits and issues relating to the auditing process are discussed.

Interventions for preventing obesity in childhood. A systematic review

Background The prevalence of obesity and overweight is increasing worldwide. Obesity in children impacts on their health in both short- and long-term. Obesity prevention strategies are poorly understood.

Objective To assess the effectiveness of interventions designed to prevent obesity in childhood.

Search strategy Electronic databases were searched from January 1985 to October 1999.

Selection criteria Data from randomized control trials and non-randomized trials with concurrent control group were included. A priori, studies with follow up of 1 year minimum were selected however, this was subsequently amended to include studies with a minimum follow up of three months.

Data collection & analysis Two reviewers independently extracted data and assessed study quality.

Main results Seven studies were included, three long-term (>1 years) and four short-term (>3 months and <1 years). The studies included were diverse in terms of study design and quality, target population, theoretical underpinning of intervention approach, and outcome measures. As such, it was not appropriate to combine study findings using statistical methods.

Conclusions Two of the long-term studies (one focused on dietary education and physical activity vs. control, and the other only on dietary education vs. control), resulted in a reduction in the prevalence on obesity, but the third, which focused on dietary education and physical activity, found no effect. Of the four short-term studies, three focused simply on physical activity/reduction of sedentary behavious vs. control. Two of these studies resulted in a reduction in the prevalence of obesity in intervention groups compared with control groups, and another study found a non-significant reduction. The fourth study focused on dietary education and physical activity, and did not find an effect on obesity, but did report a reduction in fat intake. Overall, the findings of the review suggest that currently there is limited quality data on the effectiveness of obesity prevention programmes and as such no generalizable conclusions can be drawn. The need for well-designed studies that examine a range of interventions remains a priority.

Recounting a difficult past : a South African accounting firm's "experiences in transformation"

This article examines the role of oral history in the social construction of collective memory and forgetting. The article presents a case study of a South African public accounting firm's attempt to document the history of race relations within the firm through the publication of a collection of oral histories. The research draws from the sociology of memory and recent scholarship on individual and collective memory in South Africa to analyze the firm's account of its experiences in making the transition from Apartheid to a multiracial democracy. The analysis finds that the firm's portrayal of its history reflects a narrative of reconciliation and redemption that minimizes the deep social and economic divisions that characterize South Africa's past, their relevance to accounting history, and the continuing salience of race to employment in public accounting.

Risk factors for violence and relational aggression in adolescence

Analyses examined risk factors for seventh- and ninth-grade youth  categorized as nonoffenders, physically violent, relationally aggressive, and both violent and relationally aggressive. Bivariate and multivariate results showed that relationally aggressive youth were elevated on most risks above levels for nonoffenders but lower than those for youth who were violent alone or violent in combination with relational aggression. Youth who were both relationally aggressive and violent did not differ from those who were violent alone on most risk factors examined. Peer, individual, and family risks were among the strongest predictors.

Parenting a preterm infant: experiences in a regional neonatal health services programme

In an Australian regional health service, parents’ experiences of the neonatal intensive care (NICU), neonatal nurseries and a community discharge programme were investigated. Parents from 12 families participated in an in-depth interview. Three themes captured a partial, yet significant, view of these parents’ experiences as they strived to develop their identity and competence as parents. The findings are explored as they reveal issues associated with the provision of family centred, developmental care in neonatal services. Opportunities for nurses in this context to expand and clarify their role in ways that are responsive to parenting needs are discussed.
