Production, properties and processing of American bison (Bison bison) wool grown in southern Australia

American bison grow a thick coat of fibres which assists them to withstand severe climatic conditions. Bison fibre was traditionally used in textiles by native North Americans. This study aimed to quantify the production, fibre attributes and dehairing processing of bison fibre produced from bison grazed in north-eastern Victoria. Three age/sex classes were sampled (n = 16) at seven body positions in spring. The fibre growing area was measured. Fibre was tested for diameter distribution, clean washing yield, proportion of fine fibres <36µm and fine fibre length, and processed by cashmere dehairing. Bison were 12 years of age, liveweights 160450 kg and had mean fibre growing area of 1.4 m². They produced an average 1184 g (range 5301640 g) of fine fibre with mean fibre diameter 18.5µm, clean washing yield 76.5%, wax content 9.8%, suint content 14.5%, clean fine fibre yield 56.4%, fine fibre length 37 mm and fibre curvature was 93/mm. Mid-side fibre had a crimp frequency of 6.5/cm and mean resistance to compression of 6.6 kPa. Fibre had a tenacity of 8.7 cN/tex and an extension of 39.3%. Restricted maximum likelihood mixed model analysis showed age/sex class and sampling site significantly affected all fibre attributes. Finer and longer fibre was produced in anterior sites and in younger bison. Fibre curvature declined 5.3°/mm for each 1-µm increase in mean fibre diameter. Dehaired fibre had a mean fibre diameter of 17.8 µm and mid-length of 28 mm, suitable for woollen spinning. The production by bison of coats containing significant amounts of fibre indicates that careful harvesting of fibre could form an important source of income in bison enterprises.

From cholera outbreaks to pandemics : the role of poverty and inequality

Cholera and other diarrheal diseases are the second leading cause of death among the poor globally. The tragedy of this statistic is that it need not be the case. Unlike many afflictions, the impact of cholera can be greatly reduced, if not eliminated, through the provision of clean water services. This begs the question of why such provision is absent in much of the world. It is our contention that the provision of clean water services is an increasing function of both a country's level of income and income equality. We test these hypotheses by analyzing 1,032 annual observations arising from 55 relatively poor countries between the years 1980 and 2002. In the primary part of the analysis, we find that providing clean water is, as predicted, an increasing function of income and equality. Following this, and consistent with the existing epidemiological research on cholera, we find that both the numbers of cases and deaths resulting from a given cholera outbreak are strongly and negatively related to the provision of clean water.

Northern Lights: the positive policy example of Sweden, Finland, Denmark and Norway

The nations of Scandinavia and Finland, or Nordic Europe, continue to provide living proof that economic prosperity can be combined with social equality and environmental responsibility. This book, written from an Australian perspective, explores previous outside policy interest in the Nordic nations and outlines some lessons which the English-speaking world, in particular, can learn now from the achievements of the four main Nordic European nations. In terms of income distribution these countries are still much more equal than Australia, Britain, New Zealand and Canada – and nearly twice as equal as the United States. Workforce participation rates are high in the Nordic nations but working hours remain within reasonable limits, enabling genuine work–life balance. Sweden has played a leading role in improving wellbeing, and lowering poverty, among children. Finland has achieved stunning success in schools since the 1990s. Denmark invests in comprehensive skills training as part of providing security, as well as flexibility, in people’s employment lives. Norway’s taxation approach and other measures ensure that its natural resources are used sustainably for the entire nation’s long-term wealth. All of these achievements are relevant to the policy choices for the future which Australia, and other English-speaking countries, can now make.

Does education reduce income inequality? A meta-regression analysis

This paper reexamines the effects of education on inequality through a comprehensive meta-regression analysis of the extant empirical literature. We find that education affects the two tails of the distribution of income: Education reduces the income share of top earners and increases the share of the bottom earners. Education has been particularly effective in reducing inequality in Africa. Some of the results suggest that secondary schooling appears to have a stronger effect than primary schooling, though this finding is not always robust. The heterogeneity in reported estimates can be largely explained by differences in the specification of the econometric model and measure of inequality and education. © 2013 John Wiley & Sons Ltd.

External impact of arts management research: An extended analysis

Arts management is a discipline whose research domain has grown in impact over the last quarter century.This study provides an external thematic, content and citation analysis of arts management articles in top-tiermainstream management and marketing journals between 1987 and 2010. It explicates article, author andcitation frequencies based on author information, publication patterns and thematic citation metrics, thuscontributing to the development of the arts management body of knowledge. Specifically, the study examinesthe function of arts management research as a bridging mechanism to its parent disciplines in managementand marketing. The authors identify thematic citation metrics of research published in mainstream journalsas well as frequencies and publication patterns, so that scholars can make decisions affecting their futureresearch directions. The authors conclude that there is little correlation between age/rank of journal andfrequency of citations, with younger journals becoming established as key players within relatively shortperiods.

Transcriptomics-based analysis using RNA-Seq of the coconut (Cocos nucifera) leaf in response to yellow decline phytoplasma infection

Invasive phytoplasmas wreak havoc on coconut palms worldwide, leading to high loss of income, food insecurity and extreme poverty of farmers in producing countries. Phytoplasmas as strictly biotrophic insect-transmitted bacterial pathogens instigate distinct changes in developmental processes and defence responses of the infected plants and manipulate plants to their own advantage; however, little is known about the cellular and molecular mechanisms underlying host–phytoplasma interactions. Further, phytoplasma-mediated transcriptional alterations in coconut palm genes have not yet been identified. This study evaluated the whole transcriptome profiles of naturally infected leaves of Cocos nucifera ecotype Malayan Red Dwarf in response to yellow decline phytoplasma from group 16SrXIV, using RNA-Seq technique. Transcriptomics-based analysis reported here identified genes involved in coconut innate immunity. The number of down-regulated genes in response to phytoplasma infection exceeded the number of genes up-regulated. Of the 39,873 differentially expressed unigenes, 21,860 unigenes were suppressed and 18,013 were induced following infection. Comparative analysis revealed that genes associated with defence signalling against biotic stimuli were significantly overexpressed in phytoplasma-infected leaves versus healthy coconut leaves. Genes involving cell rescue and defence, cellular transport, oxidative stress, hormone stimulus and metabolism, photosynthesis reduction, transcription and biosynthesis of secondary metabolites were differentially represented. Our transcriptome analysis unveiled a core set of genes associated with defence of coconut in response to phytoplasma attack, although several novel defence response candidate genes with unknown function have also been identified. This study constitutes valuable sequence resource for uncovering the resistance genes and/or susceptibility genes which can be used as genetic tools in disease resistance breeding.

Financial integration: the role of tradable and non-tradable goods

This paper examines the potential benefits of financial integration focusing on the role of tradable and non-tradable goods. We construct a new country-level index for tradability of output using disaggregate sector level data on output, imports and exports. Cross-country regressions show that for the overall sample, there is a weak positive interaction of tradibility of output and financial integration. When we focus on those countries within a middle range of institutional development, and thus within the middle range of income per capita, for these countries, the experience of integration is tempered significantly by increasing tradability of output. Sector-level regressions confirm the negative and significant interaction of trade and financial integration for this sample of countries.

High colonization by native arbuscular mycorrhizal fungi (AMF) of rubber trees in small-holder plantations on low fertility soils in North East Thailand

Rubber tree is a very important crop in Thailand, representing an essential source of income for farmers. In the past two decades, rubber tree plantations have been greatly expanding in unfavorable areas, where climate conditions are difficult and soil fertility is very poor. To optimize latex yields, mineral fertilizers have been widely used. A better understanding of the roles of the biological compartment in soil fertility is essential to determine alternative management practices to sustain soil fertility and optimize latex yields. Arbuscular mycorrhizal fungi (AMF) are widely recognized as beneficial for plants, mainly through their role in improving plant nutrient uptake. The objective of this study was to assess the AMF populations in rubber tree plantations and the impact of both soil characteristics and plantation age on these communities. Our results showed that all rubber trees were highly colonized, regardless of the soil structure and nutrient contents. AMF colonization was not affected by the age of the trees, suggesting that maintaining the symbiosis is likely to be beneficial at all stages. A better understanding and management of the microbial communities would contribute to maintaining or restoring soil fertility, leading to a better tree growth and optimized latex yield.

Physicochemical characteristics, functional properties, and nutritional benefits of peanut oil: a review

The legume Arachis hypogaea, commonly known as peanut or groundnut, is a very important food crop throughout the tropics and subtropics. Peanut is one of the most widely used legumes due to its nutrition and taste, and it occupies a rank of major oilseed crop in the world. It has been recognized as a functional food due to its role in a health promoting effect. Peanut oil contains a well-balanced fatty acid and antioxidant profile that provide protection against harmful substances especially free radicals. This paper gives an overview of scientific literature available on phytochemical and functional properties of peanut oil. Owing to its unique organoleptic properties associated with its cardioprotective and anti-inflammatory properties, peanut oil has found, recently, its place on the highly competitive international edible oil market.

Globalization, international trade and welfare

The term globalization is generally used to describe an increase in international transactions in markets for goods and services and factors of production, plus the growth and expanded scope of mar.y institutions that straddle international borders. Globalization has also led to a more liberal economic environment where issues such as labour standards, human rights, the environment, intellectual property rights, investment codes and competition policy are now considered legitimate topics in the trade debate. Free global markets cannot guarantee that air, water or energy resources are accurately priced for sustainable development since there is no mechanism to internalize environmental costs. Economic growth, although a powerful tool for increasing a country's wealth, cannot guarantee that such wealth will be equally distributed. What is needed is environmental and social policy to redistribute the benefits.
Recent empirical studies show that there are clear signs of income convergence among countries that integrate more fully with the world economy but a divergence between these active participants and those who elect to remain insulated from global markets. The inequality within nations (distribution of income) has increased during the period of globalization over the last fifty years.

Women in research? Investigating research opportunities for female academics in Australia

Women continue to be surprisingly under-represented in academia, given the increasing numbers of female postgraduate students and the flexible working conditions offered by most Australian Universities. To date, research has emphasised multiple causes for the 'gender gap' in academia, including the structural characteristics of the university system, cultural and societal barriers to the advancement of women, the influence of marital status on the productivity of women academics and the interaction of cultural, social and personality factors on women's professional careers. However, the implications of a 'gender gap' in academic rank reach beyond arguments of equality between sexes, to questions regarding consequences of a male-dominated professoriate to the nature and subjects of academic research in Australia. The aim of this paper is to investigate the factors that determine the rank of Australian academics and in part, to investigate whether there is a gender gap of rank or authority, through an analysis of data collected on all Australian academics by the Federal Department of Education, Science and Training. The implications of these findings on opportunities for female academic researchers and for research outcomes will be discussed.

Living alone, social support, and feeling lonely among the elderly

This study aimed to describe the characteristics of the elderly population living alone, and to examine how living alone relates to feeling lonely. Interviews were conducted with a stratified random sample of 4,859 elderly individuals living in Kaohsiung, Taiwan. Variables collected included demographic information, living alone or not, activities of daily living
(ADL), instrumental activities of daily living (IADL), Short Portable Mental Status Questionnaire (SPMSQ), chronic conditions, perceived social support, and a subjective measure of feeling lonely. Using logistic regression, it was found that factors associated with living alone included gender, marital status, occupation, source of income, religion, and IADL. Living alone was, in tum, related to decreased levels of both perceived social support
and feeling lonely after adjustment for potential confounders. Managing retired life is important for adult elders, particularly for men. Lack ofsocial support is common among the elderly community who live alone, which could wel1 be a main reason for this group to feel lonely. As loneliness is linked to physical and mental health problems, increasing social support and facilitating friendship should be factored into life-style management for
communities of elderly.

Projecting the U.S. gender wage gap 2000-40

This paper projects the gender wage gap for 25–64 year old Americans for the period 2000–40. The analysis uses data from the Panel Survey of Income Dynamics (PSID) for 1995 and 1996 together with the U.S. Census Bureau demographic projections. The method combines the population projections with assumptions regarding the evolution of educational attainment in order to first project the future distribution of skills and, based on these projections, the future size of the gender wage gap. The main set of projections suggests that changing skill characteristics—specifically educational attainment—will continue to close the gender wage gap. However, even in 2040, a substantial pay gap of at least 75 percent of the size of that in 1995 will remain.

Strategic vote manipulation in a simple democracy

In both the Employee Stock Ownership Plan (ESOP) and employee buyouts, the common and crucial phenomenon is that some workers have two sources of income, namely wages and shares of profit. We analyze that phenomenon in an economy where workers are nonunionized and wages are determined by voting. If the employers sell a certain amount of shares of the capital stock to some non-risk-loving workers, these workers vote for the lowest possible wage along with the employers. As a result, all workers become equally worse off because of the competition among workers to buy those shares.
