Reconsidering the state : cosmopolitanism, republicanism and global governance

Cosmopolitan arguments for global forms of democracy and governance have intensified in the last decade because of the increasing significance of transnational interconnections and the increased impact of global problems. However, questions remain as to how cosmopolitan structures are going to be realized in practice, given the continued significance of the state in global politics. This paper advocates the importance of considering republican arguments for redeveloping the state alongside the proposals for global democratic structures advocated by political cosmopolitans such as David Held. It contends that many forms of cosmopolitan thought are too quick to dismiss the state as a potential locus of ethical global governance and that republican conceptions of the state and political practice are important counterpoints to political cosmopolitanism. Consequently, this paper critically considers the assumptions embedded in the literature of political cosmopolitanism in relation to the proposals for global democracy and governance. Then the paper considers republican arguments that developing civically minded citizens and responsive state institutions could be a crucial foundation for transnational forms of governance to be realized in practice. The paper then concludes by considering the practical tensions between republican and cosmopolitan proposals.

The 'caffeine-sweetness' effect; potential reduction of energy in caffeinated sugar-sweetened soft drinks

Background – Excessive consumption of sugar sweetened beverages (SSB) is a contributing factor in the occurrence of overweight and obesity. The high energy intake, low satiation, high glycemic index, and intense marketing are all thought to contribute to their over consumption. In addition, the role of the mildly-addictive chemical caffeine in SSB has been questioned (Griffiths and Vernotica, 2000, Keast and Riddell, 2007). We have previously shown that low concentrations of caffeine may decrease sweetness of sugars and thereby result in excess energy in SSB formulations (Ebbeling et al., 2006).
Objective – Without noticeably affecting flavour, to determine potential energy reduction when decreasing sucrose concentration from caffeinated and de-caffeinated SSB.
Design – Human psychophysical taste evaluations in water, sucrose and model SSB. Triangle forced-choice ascending method of limits was used to determine caffeine taste threshold in water and sucrose (n= 62). Directional paired comparison tests to determine 1/ the influence of caffeine on sweetness of sucrose (n= 23), and 2/ the nonperceivable difference when decreasing the sucrose and caffeine concentrations in a model SSB (n= 30).
Outcomes – Caffeine, at sub-threshold concentrations in common SSB (0.67mM) can be perceived in sucrose solutions because it significantly inhibits sweetness (p<0.001), the ‘caffeine sweetness effect’. Presumably coremoval of caffeine and sucrose could be achieved without affecting the sweetness of the SSB. Removing caffeine from the model SSB allowed an energy reduction of 137.4 KJ per 500 ml serving (12.6% sucrose reduction) without noticeably affecting flavour for 80% of the population. The energy reduction possible without co-removal of caffeine was a more modest 32 KJ per 500 ml serving (3.5% sucrose reduction).
Conclusion – Sub-threshold concentrations of caffeine suppress sweetness resulting in higher concentrations of sugars in SSB. Excessive consumption of SSB is linked to the obesity epidemic, and we suggest the removal of caffeine and subsequent removal of 137.4 KJ energy will have long term public health benefits.

Whey protein and gum arabic encapsulated Omega-3 lipids. The effect of material properties on coacervation

The effect of material properties on complex coacervation of whey protein and gum Arabic from various sources was investigated. In this study, it was demonstrated that material properties of whey protein isolates and gum Arabic affect the complex coacervation process significantly. For whey protein, the coacervation capability could be correlated with their level of denaturation and calcium content. For gum Arabic, both material sources and salt content were found to be attributing factors to their coacervation capability. This study facilitated the development of Omega-3 lipids microcapsules with promising performances in certain food applications.

Predictors of body mass index change in Australian primary school children

Objective. To assess associations between multiple potential predictors and change in child body mass index (BMI). Methods.In the 1997 Health of Young Victorians Study, children in Grades preparatory to three (aged 510 years) had their height and weight measured. Parents provided information on potential predictors of childhood overweight across six domains (children’s diet, children’s activity level, family composition, sociodemographic factors, prenatal factors and parental adiposity). Measures were repeated three years later in 2000/1. BMI was transformed to standardised (z) scores using the US 2000 Growth Chart data and children were classified as non-overweight or overweight according to international cutpoints.Regression analyses, including baseline BMI z-score as a covariate, assessed the contribution of each potential predictor to change in BMI z-score, development of overweight and spontaneous resolution of overweight in 1 373 children.Results. BMI z-score change was positively associated with frequency of take-away food, food quantity, total weekly screen time, non-Australian paternal country of birth, maternal smoking during pregnancy, and maternal and paternal BMI.Inverse associations were noted for the presence of siblings and rural residence (all pB0.05). Predictors of categorical change (development and resolution of overweight) were less clearly identified, apart from an association between maternal BMI and overweight development (p0.02). Multivariable models suggested individual determinants have a cumulative effect on BMI change. Conclusions. Strong short-term tracking of BMI makes it difficult to identify predictors of change. Nonetheless, putative determinants across all domains assessed were independently associated with adiposity change. Multi-faceted solutions are likely to be required to successfully deal with the complexities of childhood overweight.

Effect of deer velvet on sexual function in men and their partners: a double-blind, placebo-controlled study

The use of alternative medicines and herbal remedies is an increasing trend in Western societies. For years, people have taken products made of deer velvet for their alleged beneficial effects on sexual function. There has been no scientific investigation of the effects of deer velvet powder on the sexual functioning of human males. This study investigated sexual function in men during a 12-week double-blind, placebo-controlled trial of deer velvet. Thirty-two volunteer male participants, aged 45–65 years, and their partners, were randomly assigned to either the deer velvet or placebo study group. The males took capsules containing ground deer velvet or placebo everyday for 12 weeks. Two sexual function questionnaires (the International Index of Erectile Function and the Brief Index of Sexual Function for Women) used at pre- and posttreatment assessed changes in sexual functioning in males and their partners. Blood tests at baseline, and end of study, determined levels of sex-related hormones in male participants. There were no significant differences in the sexual behavior of the men taking deer velvet compared with the men taking placebo capsules. There were no significant hormone changes from baseline to the end of the study in either group of men. We conclude that in normal males there was no advantage in taking deer velvet to enhance sexual function. All alternative health products or nutritional supplements should be subjected to randomized placebo-controlled trials to determine efficacy.

Annual variation in the distribution of summer snowdrifts in the Kosciuszko alpine area, Australia, and its effect on the composition and structure of alpine vegetation

Australian alpine ecosystems are expected to diminish in extent as global warming intensifies. Alpine vegetation patterns are influenced by the duration of snow cover including the presence of snowdrifts in summer, but there is little quantitative information on landscape-scale relationships between vegetation patterns and the frequency of occurrence of persistent summer snowdrifts in the Australian alps. We mapped annual changes in summer snowdrifts in the Kosciuszko alpine region, Australia, from Landsat TM images and modelled the frequency of occurrence of persistent summer snowdrifts from long-term records (1954–2003) of winter snow depth. We then compared vegetation composition and structure among four classes that differed in the frequency of occurrence of persistent summer snowdrifts. We found a curvilinear relationship between annual winter snow depth and the area occupied by persistent snowdrifts in the following summer (r²=0.9756). Only 21 ha (0.42% of study area) was predicted to have supported summer snowdrifts in 80% of the past 50 years, while 440 ha supported persistent summer snow in 10% of years. Mean cover and species richness of vascular plants declined significantly, and species composition varied significantly, as the frequency of summer snow persistence increased. Cushion plants and rushes were most abundant where summer snowdrifts occurred most frequently, and shrubs, grasses and sedges were most abundant in areas that did not support snowdrifts in summer. The results demonstrate strong regional relationships between vegetation composition and structure and the frequency of occurrence of persistent summer snowdrifts. Reductions in winter snow depth due to global warming are expected to lead to substantial reductions in the extent of persistent summer snowdrifts. As a consequence, shrubs, grasses and sedges are predicted to expand at the expense of cushion plants and rushes, reducing landscape vegetation diversity. Fortunately, few vascular plant species (e.g. Ranunculus niphophilus) appear to be totally restricted to areas where summer snow occurs most frequently. The results from this study highlight potential indicator species that could be monitored to assess the effects of global warming on Australian alpine environments.

A measurement framework for international entrepreneurship policy research : from impossible index to malleable matrix

The Global Entrepreneurship Monitor (GEM), a multifaceted, multinational research programme now in its seventh year of field operation, currently dominates the field of international entrepreneurship policy research but faces a crisis of credibility. Despite having created and continuing to develop a very rich database capable of addressing many of the complexities requisite for understanding entrepreneurship at the national and international levels of analysis, GEM has chosen to disguise the depths of its potential research and policy utility through a misnamed quest for unobtainable simplicity at the centre of the project and a disorganised variety of report presentations at the periphery. Subsequent to a review of the entrepreneurial definitional literature and a resolution of its many themes into six components of entrepreneurial activity, based on Penrose's (1959/1995) articulation of the practical meaning of 'entrepreneurial services', this paper suggests that a 'malleable matrix' approach can provide a practical measurement framework capable of reporting national entrepreneurial activity in a structure that is comprehensive without being overwhelming.

Office buildings and the environment : the increasing role of facility managers

The Australian commercial stock emits 12% of all greenhouse gas emissions however the commercial property market has some inherent barriers to sustainability (DSE, 2005). A substantial proportion of the stock is owned by institutional investors who are unconvinced by the need to improve their stock and pass on running costs to tenants (Callender & Key, 1997). The links between the built environment and sustainability issues such as fossil fuel consumption and climate change is clear. In developed countries buildings contribute around half of all carbon dioxide emissions and offer considerable scope for a significant contribution to sustainability through ecologically aware design and increased energy efficiency (BRE, 1996). As capital values are not greatly affected by sustainability, owners react by doing little or nothing and the effect is to limit sustainability-related investment and undermine efforts to deliver sustainability in the sector. Facility managers are in an influential position to help address sustainability issues via an increased awareness of energy efficiency and CO2 emissions.

Even though the efficiency of buildings is primarily focused on new stock, with an existing churn replacement rate of approximately 2-3% the existing stock must be improved if urban built environment greenhouse gas emissions are to be reduced – clearly the management of existing stock must therefore contribute to substantial savings in energy use. Much of the property and surveying research has previously adopted an illustrative case study approach advocating the benefits of ESD and energy efficiency in existing buildings. This research adopts a radically different approach and profiles the entire office stock of a global CBD, namely Melbourne, which is seeking to become a carbon neutral city by 2020 (City of Melbourne, 2003). The research also employs scenario forecasting to model future changes to the stock over a fifteen year period. This paper sets out the rationale for the research and establishes the methodological approach adopted by the research team. The results provides a unique insight into the variations between different building types and grades of office buildings, which in turn will allow facility managers to gain a better understanding of where gains in energy efficiency can be made.

Gillian Brock, Global justice : a cosmopolitan account

This is a review of Gillian Brock’s new book, Global justice: a cosmopolitan account (Oxford: Oxford University Press, 2009) which sets out the central theses of the book and then offers a critical appraisal of its central arguments. My specific concern is that Brock gives an insufficiently robust account of human rights with which to define the nature of global justice and thereby leaves cosmopolitanism too vulnerable to the normative pull of local and traditional moral conceptions that fall short of the universalism that cosmopolitans should be able to embrace.

The effect of type of cereal on the glycaemic response of two traditional Sri Lankan food items

Pittu and roti are two traditional food items consumed by Sri Lankan people mostly for breakfast or dinner. Rice (Oryza sativa L.) and kurakkan (Eleucine coracana L.) are two types of cereal that can be used to prepare them. The determination of blood glucose elevating effect (glycaemic response) of pittu and roti prepared from rice flour and kurakkan flour was the objective of this study. Proximate composition of Bg 403 rice flour and kurakkan flour was determined and the available carbohydrate content of the two types of cereal was calculated. Pittu and roti were prepared from each flour, following traditional methods and given to eight young healthy adult volunteers. Each subject was given a weighed portion of pittu or roti equivalent to 50 g available carbohydrate as the test food. As the standard food 50 g glucose was given orally. After a 12 hrs overnight fast on the assigned day each subject was given either the standard food or the test food and blood glucose was measured in capillary blood at fasting (0), 15, 30, 45, 60, 90 and 120 min after the consumption of food. The incremental area under the glycaemic response curve (IAUC) for each test food was expressed as a percentage of IAUC of the standard food taken by the same subject and the average value of subjects was taken as the glycemic index (GI) for the test food. Proximate analysis revealed that percentage moisture, crude fat, crude fibre, crude protein and minerals of rice flour and kurakkan flour were 13.0, 1.7, 0.42, 10.3, 0.88 and 13.2, 1.9, 4.4, 8.7 and 2.8, respectively. Accordingly the available carbohydrate percentage of rice flour and kurakkan flour were 73.7 and 69.0, respectively. The GI of pittu and roti, prepared using Bg 403 rice flour were 52 and 64 and that of kurakkan flour were 71 and 80 respectively. Based on the GI, it can be suggested that pittu is better for health than roti, while rice flour is better than kurakkan flour to prepare these. The basis of recommending kurkkan flour based products for diabetic people has to be re-examined in the light of these findings.

Wealth effect of auditor switch during crisis and non-crisis period : the Malaysian experience

This study examines the auditor switch effect on share prices among listed companies in Malaysia, mainly the Second Board companies during economic crisis and the economic growth period. Data on companies listed on the KLSE that reported switching of auditors were gathered from the respective companies’ annual reports for the period of 1990 until 1999. Daily stock prices and the Second Board Index for an interval of 200 days windows were extracted from the KLSE Daily Dairy. The wealth effect of auditor’s switch was investigated using the market model event study methodology. The general findings of the study imply that it is consistent with the theory, the market reacts positively to news involving switching to higher prestige audit firms before the economic crisis but reacted negatively during the economic crisis. News involving switching to lower prestige auditors received negative reaction both before and during the crisis. This study postulate that the negative reaction to switches during the economic crisis (either to higher prestige or to lower prestige auditors) may be due to cost cutting exercise rather than obtaining qualified audit reports.

The halloween effect and Japanese equity prices : myth or exploitable anomaly

Bouman and Jacobsen (American Economic Review 92(5), 1618–1635, 2002) examine monthly stock returns for major world stock markets and conclude that returns are significantly lower during the May–October periods versus the November–April periods in 36 of 37 markets examined. They argue that, in general, the Halloween strategy outperforms the buy and hold strategy thereby casting doubt on the validity of the efficient market paradigm. More recently, Maberly and Pierce (Econ Journal Watch 1(1), 29–46, 2004) re-examine the evidence for U.S. equity prices and conclude that Bouman and Jacobsen’s results are not robust to alternative model specifications. Extending prior research, this paper examines the robustness of the Halloween strategy to alternative model specifications for Japanese equity prices. The Halloween effect is concentrated in the period prior to the introduction of Nikkei 225 index futures in September 1986. After the internationalization of Japanese financial markets in the mid-1980s, the Halloween effect disappears.

Effect of erectile dysfunction medications on coexsisting dysfunctions in couples : Partner's Preference Study

There is sparse information on how treatments for erectile dysfunction (ED) affects couples. This study investigated the effects of ED treatments on 100 heterosexual couples' sexual functioning and whether function achieved using a short-acting versus a long-acting ED medication differed significantly. Couples were randomized to use tadalafil or sildenafil for each of two 12-week study phases; they completed questionnaires (International Index of Sexual Function and Female Sexual Function Index) and kept sexual event diaries. All participants experienced significant improvements over baseline sexual functioning, while the men used short- or long-acting ED medications with no significant differences related to the duration of drug action recorded for either the men or women. Despite this lack of difference in efficacy there was a strong preference by women (79%) and their partners (16%) for the longer-acting medication. The reasons for this warrant further investigation. Understanding the effects on couples of the use of ED medications is a necessary aspect of ensuring ongoing sexual satisfaction in couples treated for ED.

Effect of pre-straining and bake hardening on the microstructure and mechanical properties of CMnSi trip steels

The effects of pre-straining and bake hardening on the mechanical behaviour and microstructural changes were studied in two CMnSi TRansformation-Induced Plasticity (TRIP) steels with different microstructures after intercritical annealing. The TRIP steels before and after pre-straining and bake hardening were characterised by X-ray diffraction, optical microscopy, transmission electron microscopy, three dimensional atom probe and tensile tests. Both steels exhibited discontinuous yielding behaviour and a significant strength increase with some reduction in ductility after pre-straining and bake hardening treatment. The following main microstructural changes are responsible for the observed mechanical behaviours: a decrease in the volume fraction of retained austenite, an increase in the dislocation density and the formation of cell substructure in the polygonal ferrite, higher localized dislocation density in the polygonal ferrite regions adjacent to martensite or retained austenite, and the precipitation of fine iron carbides in bainite and martensite. The mechanism for the observed yield point phenomenon in both steels after treatment was analysed.
