Temporal causality between human capital and real income in cointegrated VAR processes : empirical evidence from China, 1960-1999

This article examines the causal relationship between human capital and real income using data for China from 1960 to 1999. In the long run there is unidirectional Granger causality running from human capital to real income, while in the short run there is unidirectional Granger causality running from real income to human capital

Temporal causality and the dynamics of democracy, emigration and real income in Fiji

This study is the first to explore temporal causality between democracy, emigration and real income in Fiji within a multivariate cointegration model. We find three long run relationships between democracy, emigration and real income. In the long run there is evidence that migration and democracy Granger cause real GDP in Fiji; real GDP and democracy Granger cause migration from Fiji and that real GDP and migration Granger cause democracy in Fiji. In the short run we find unidirectional Granger causality running from migration to real GDP and from democracy to real GDP, but neutrality between democracy and migration in the short run. We also extend the analysis to examine the degree of exogeneity of the variables beyond the sample period through considering the decomposition of variance and impulse response functions.

Electricity consumption, employment and real income in Australia evidence from multivariate Granger causality tests

This paper examines the relationship between electricity consumption, employment and real income in Australia within a cointegration and causality framework. We find that electricity consumption, employment and real income are cointegrated and that in the long-run employment and real income Granger cause electricity consumption, while in the short run there is weak unidirectional Granger causality running from income to electricity consumption and from income to employment.

Variations in vascular access flows in haemodialysis can depend on needle orientation

Introduction: While using the Transonic Qc[TM] machine to assess access flow in arteriovenous fistulae (AVF), we observed that when compared to antegrade arterial needle insertion, retrograde arterial needle insertion could regularly produce lower access flow measurements. This study sought to explore this phenomenon.

Method: 23 patients entered and 20 finished the study. Patient selection criteria included: functioning AVF and an adequate AVF length for either retrograde or antegrade arterial needle insertion. After ensuring stable and similar blood pressures, 3 flow measurements were taken during the first 2 hours on the same dialysis day of 3 consecutive weeks using antegrade needle insertion then were repeated on 3 further consecutive weeks using retrograde insertion.

Results: Overall, access flows measured with retrograde insertion were significantly lower by a mean difference of 107.15 ml/min (57-484 ml/min) than the flows measured with antegrade needle placement. In 5/20, 3 recorded minimal difference and 2 had a higher access flows during retrograde insertion. No recirculation was observed during either antegrade or retrograde needle insertion. The paired t-test showed that there was significant difference between the antegrade versus retrograde mean measurements (p = 0.005).

Conclusion: Although the sample size is small and the number of measurements limited, we conclude that access flows may be greater with an antegrade arterial orientation compared to flows recorded with a retrograde orientation. The phenomenon behind this conclusion is yet to be investigated. We suggest that when using the Transonic Qc[TM] access measurement device the arterial needle should always be in the same direction for each measurement for each individual patient.

Sustainable living environment for urban low-income households in Malaysia : key factors for maintenance

Urbanisation is predicted to continuously increase every year. Demand for urban shelter will rise and hence this will force governments to act, within their capability, to provide affordable housing in order to maintain social and economic stability. Some industrialized countries have demonstrated full state support from planning and implementation through to continuing maintenance in order to create and sustain a healthy living environment for urban low-in-come households. For developing countries, this might be more difficult. Ensuring adequate maintenance to provide housing quality over the long term is proving even more problematic than simply providing housing. The question is how housing in developing countries can be made sustainable in order to provide a better living environment in the long term. This study focuses on key issues of residential living environments for urban low-cost housing in Malaysia in relation to housing maintenance management. Drawing from extensive primary research and a series of interviews, this exploratory study identifies factors that must be considered by policy makers in order to provide a decent and sustainable living environment for the urban lower-income group. The outcome suggests that current systems of maintenance management - offsetting maintenance to developers or the housing communities themselves, is not working well. The government may need to continue to support low cost housing through maintenance in order to prevent deterioration of accommodation that could become future slums.

Measuring non-economic well-being achievement

Income per capita and most widely reported, non- or non-exclusively income based human well-being indicators are highly correlated among countries. Yet many countries exhibit higher achievement in the latter than predicted by the former. The reverse is true for many other countries. This paper commences by extracting the inter-country variation in a composite of various widely-reported, non-income-based well-being indices not accounted for by variations in income pre capita. This extraction is interpreted inter alia as a measure of non-economic well-being. The paper then looks at correlations between this extraction and a number of new or less widely-used well-being measures, in an attempt to find the measure that best captures these achievements. A number of indicators are examined, including measures of poverty, inequality, health status, education status, gender bias, empowerment, governance and subjective well-being.

Non-economic well-being achievement in Pacific Asia

It is well known that income per capita and most widely reported non-economic well-being achievement measures are highly correlated among countries. Yet many countries exhibit higher achievement in the latter than predicted by the former. The reverse is true for many other countries. This paper commences by extracting the inter-country variation in a composite of three widely reported educational and health status indicators not accounted for by variations in income per capita. This extraction is interpreted inter alia as a measure of non-economic well-being. Using data for a sample of Pacific Asian countries, the paper then looks at correlations between this extraction and a number of new or less widely-used well-being measures, in an attempt to find the measure that best captures these achievements.

Can social cognitive theory constructs explain socio-economic variations in adolescent eating behaviours? A mediation analysis

Adolescents of low socio-economic position (SEP) are less likely than those of higher SEP to consume diets in line with current dietary recommendations. The reasons for these SEP variations remain poorly understood. We investigated the mechanisms underlying socio-economic variations in adolescents’ eating behaviours using a theoretically derived explanatory model. Data were obtained from a community-based sample of 2529 adolescents aged 12–15 years, from 37 secondary schools in Victoria, Australia. Adolescents completed a web-based survey assessing their eating behaviours, self-efficacy for healthy eating, perceived importance of nutrition and health, social modelling and support and the availability of foods in the home. Parents provided details of maternal education level, which was used as an indicator of SEP. All social cognitive constructs assessed mediated socio-economic variations in at least one indicator of adolescents’ diet. Cognitive factors were the strongest mediator of socio-economic variations in fruit intakes, while for energy-dense snack foods and fast foods, availability of energy-dense snacks at home tended to be strong mediators. Social cognitive theory provides a useful framework for understanding socio-economic variations in adolescent's diet and might guide public health programmes and policies focusing on improving adolescent nutrition among those experiencing socio-economic disadvantage.

Applying socio-cultural lenses to childhood obesity prevention among African migrants to high-income western countries : the role of acculturation, parenting and family functioning

Migration from third-world and low-income countries to high-income Western countries presents significant challenges for individuals and families, and for health service providers in the receiving societies. Cultural conflicts related to preferred body size/shape and parenting practices, together with differential inter generational rates and styles of acculturation, can affect nutritional and lifestyle choices and be associated with high rates of childhood obesity. Using African cultures as an example, this paper examines these issues. It concludes that, in designing and implementating obesity prevention programmes, health service providers need to understand these factors and how they play out.

The role of agregate demand and supply shocks in a low-income country : evidence from Bangladesh

This paper explores the relative role of aggregate demand and supply shocks in affecting the output level and inflation rate in a low-income country vulnerable to various economic shocks. The study uses Bangladesh data, and following Cover et al (2006), employs a modification of the Blanchard-Quah (BQ) approach, in which the two shocks are allowed to be correlated. Strong evidence is found for the hypothesis that aggregate demand and supply shocks are interrelated in Bangladesh. For the case in which causality is assumed to be running from demand to supply shocks, it was found that an independent supply shock plays significant role for fluctuations in inflation, which was absent in the standard BQ model. The results suggest that a tightening of monetary policy may lead to an adverse effect on the long-run growth potential and some supply-side policies may be required to supplement contractionary monetary policy in combating inflation in Bangladesh.

Post-disaster fiction for young adults : some trends and variations

In the forty years or so since it began to develop as a sub-genre of young adult fiction, post-disaster fiction has commented on a range of issues, including perceived social fears of the time, the nature of various types of society, and what people need in order to be truly human. This paper explores how young adult post-disaster fiction makes comment on these and other issues. It argues that within this genre there are three connected sub-genres, with the disaster having a different function in each, and the nature of the comments made by each of these sub-genres tending also to be different. As its title suggests, this paper includes texts in which the focus is on life after the disaster. The genre’s strong link with both the nature of young adult fiction and with adolescence itself suggests that it will continue to flourish as a sub-genre.

Seasonal variations of total lipid and fatty acid contents in muscle, gonad and digestive glands of farmed jade tiger hybrid abalone in Australia

The lipid and fatty acid (FA) contents of muscle, gonad and digestive glands (DG) of Jade Tiger hybrid abalone were studied over the four seasons. Higher contents of total lipid and saturated fatty acids (SFA) were found in summer from muscle. For gonad the higher total lipid content was found in summer and spring whereas the SFA content peaked in summer only. For DG the higher contents of total lipid and SFA were recorded in all seasons except autumn. Winter samples showed significantly higher content of PUFA in all three types of tissue. High contents of eicosapentaenoic acid (EPA, 20:5 n−3), docosapentaenoic acid (DPA, 22:5 n−3) and docosahexaenoic acid (DHA, 22:6 n−3) were recorded in winter from muscle, although no marked variations were observed from gonad. For DG the high content of DHA was also observed in winter whilst EPA and DPA maintained high levels in all seasons except summer.
