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.

Effect of low and high glycaemic index diets on developing the risk of metabolic syndrome in rats

Several observational studies have shown that the chronic consumption of high glycaemic index diet is associated with an increased risk of developing metabolic syndrome.  This study was performed to identify the direct influences on the lipid profile and the adipose tissue deposition and the subsequent development of the risk of metabolic syndrome in rats by feeding diets of low glycaemic index (LGI) and high glycaemic index (HGI). Fifty rat weanlings (three weeks old) were equally divided into two groups and fed on either low glycaemic index diet based on high amylose, or isocaloric high glycacmic index diet for 12 weeks. Postprandial blood and tissue samples were collected at the end of the 12 weeks of feeding. The total white adipose tissue weights of the HGl fed rats (24.74 ± 0.53 glrat) were significantly higher than the LGl fed rats (15.37 ± 0.36 gh·at). The HO! led rats had higher postprandial leptin concentrations (1.86 ± 0.17 ng/ml) than LGI fed rats (1.34 ± 0.12 ng/ml). The postprandial insulin, and postprandial insulin glucose ratio were higher in the HGI fed rats (7.06 ± 0.90 ng/ml and 0.67 ± 0.01 ng/mlxmM) compared to the LGl fed rats (3.91 ± 0.4 ng/ml and 0.44 ± 0.01 ng/mlxmM). Triglycerides of the l-IGI fed rats showed higher values (I .56 ± 0.10 mM) than the LO! fed rats (l.07 ± 0.08 mM). The results indicated that LGI feeding was beneficial in preventing the conditions enhancing the cardio vascular disease whereas long-term feeding of HGI diet may increase the risk of developing metabolic syndrome in rats.

Glycemic index and glycogen

INTRODUCTION : Fatigue in sports is often associated with depletion of muscle glycogen storage. Obesity is considered to be a major barrier against physical activity in sports. In order to bring the glycogen storage to a satisfactory level sports persons tend to increase consumption carbohydrates, preferred consumption of high glycemic index (HGI) than low glycemic index (LGI) diets. But HGI foods may promote postprandial carbohydrate oxidation at the expense of fat oxidation and increase body fat gain. LGI diets that produce a low and slow glycemic response may enhance higher glycogen storage instead of fat deposition.

METHODOLOGY : To test this hypothesis, 30 male Wistar rats after weaning were given either a high glycemic index (HGI) or low glycemic index (LGI) diet for until their age of 12 weeks. Then the subjects were scarified and their plasma, serum, and muscle samples were collected. RESULTS-The study revealed that HGI diets fed rats had higher plasma cholesterol and Leptin (LGI Leptin 1.34 +/- 0.13ng/ml, HGI Leptin 2.12 +/- .20ng/ml) concentrations. It also found the liver and muscle glycogen storage in LGI diets showed higher level (LGI-liver 108 +/-3.0 mg/100g, LGI-muscle 22.6+/- 2.3g/100g) than that of HGI (HGI-liver 96 +/- 2.0mg/100g, HGI-muscle 18+/- 1.5g/100g) diets.

CONCLUSION : the long term feeding of LGI carbohydrate encourages more glycogen storage while HGI increases fat deposition. Consumption of LGI diets has an advantage over HGI diets of higher physical activity while elevating glycogen storage and reducing chances of obesity.

Introduction of electronic trading in index futures : volatility and volume effects

There is continuing debate in the US over full introduction of electronic trading in those index futures contracts that are still traded at the CME via open outcry. Since the late 1990s major international exchanges trading index futures contracts have converted to full electronic trading. Recent empirical studies have focused on effects on bid/ask spreads and related price volatility following these changes. We take a different approach and investigate and test for structural change in conditional volatility and volume effects following the shift to electronic trading in the Australian Share Price Index futures contract. Multiple Switching point GARCH models are employed with the data sampled at 5, 15 and 30-minute intervals from transaction records supplied by the Sydney Futures Exchange. There is significant evidence of structural changes in both the persistence of volatility shocks and simultaneous volume effects following the change to screen trading in this futures market.

The temporal price relationship between the stock index futures and the underlying stock index : evidence from Malaysia

The stock index futures was introduced in Malaysia in December 1995 with the launching of the futures contract on the Kuala Lumpur Stock Exchange Composite Index. Due to its recentness in the country, many issues pertaining to this equity derivatives instrument have not been explored. Thus, the development of stock index futures opens many opportunities for research in this area. This study examines the temporal relationship between the price of the Kuala Lumpur Stock Exchange Composite Index futures contract (FKLI) and its underlying stock index, the Kuala Lumpur Stock Exchange Composite Index (KLSE CI). The five-year period under study is split into three subperiods to observe the price co-movement pattern under different volatility levels. The study finds that futures market tends to lead the spot market by one day during the periods of stable market, and there is a mixed lead-lag relationship between the two markets during the period of highly volatile market.

Population monitoring of language and cognitive development in Australia : the Australian early development index

The Australian Early Development Index (AEDI) is a population measure of child development. The AEDI measures Language and Cognitive Development, Social Competence, Emotional Maturity, Physical Health and Wellbeing, and Communication Skills and General Knowledge. In Australia these data are collected by teachers for children in their first full time year of schooling. The aim of this paper is to aid people's understanding and interpretation of population measures such as the AEDI. With a greater awareness of the merits and complexities of population data clinicians and allied health professionals can play a vital role in aiding communities and policy makers to interpret and act upon the data in an intelligent way. This paper is primarily descriptive providing background information on the development and use of the instrument utilizing one of the 5 developmental domains (Language and Cognitive Development) as an example. The results show a complex relationship between children residing in differing socio-economic regions, children with English as their primary or secondary language and children who are able or not able to effectively communicate in English.

Planar waveguide refractive index profile reconstruction using global optimization

The approach taken here of reconstruction of the refractive index profile of planar waveguides involves solving a non-linear integral equation with Tikhonov regularization. Using global optimization with the new cutting angle and discrete gradient methods has yielded an acceptable reconstruction, even in the presence of significant noise in the data.

A range of econometric techniques are applied to analyse construction and house prices. The economic equilibrium and dynamic relationships among regional markets are investigated based on producer price index analysis.

Habitual active transport moderates the association of tv viewing time with body mass index

Background: Television viewing time is associated with obesity risk independent of leisure-time physical activity (LTPA). However,
it is unknown whether the relationship of TV viewing time with body mass index (BMI) is moderated by other domains of physical activity. Methods: A mail survey collected height;weight; TV viewing time; physical activity for transportation (habitual transport behavior; past week walking and bicycling), for recreation (LTPA), and in workplace; and sociodemographic variables in Adelaide, Australia. General linear models examined whether physical activity domains moderate the association between BMI and TV viewing time. Results: Analysis of the sample (N = 1408) found that TV time, habitual transport, and LTPA were independently associated with participant’s BMI. The interaction between TV time and habitual transport with BMI was significant, while that between TV time and LTPA was not. Subgroup analyses found that adjusted mean BMI was significantly higher for the high TV viewing category, compared with the low category,
among participants who were inactive and occasionally active in transport, but not among those who were regularly active. Conclusions: Habitual active transport appeared to moderate the relationship between TV viewing time and BMI. Obesity risk associated with prolonged TV viewing may be mitigated by regular active transport.

National prevalence of urogenital pain and prostatitis-like symptoms in Australian men using the National Institutes of Health Chronic Prostatitis Symptoms Index

OBJECTIVE : To provide a summary, using the National Institutes of Health Chronic Prostatitis Symptoms Index (NIH-CPSI), of the prevalence of prostatitis-like symptoms in a population-based sample of Australian men.

SUBJECTS AND METHODS : Participants were Australian men aged 16–64 years recruited as part of the Australian Longitudinal Study of Health and Relationships: a nationally representative study. In all, 1346 men completed an extensive questionnaire which included the NIH-CPSI. The index identifies six types of urogenital pain, the presence of urinary problems, and effects on quality of life. Men who reported perineal and/or ejaculatory pain or discomfort and a total NIH-CPSI pain score of ≥4 were considered as having prostatitis-like symptoms.

RESULTS : Based on a weighted population of 1373 men, some form of urogenital pain was reported by 105 (7.6%) men; with 2.8% of men reporting more than one type of urogenital pain. The mean (range) NIH-CPSI pain score for men reporting pain was 6.2 (5.6–6.8); for all men the mean score was 0.5 (0.4–0.6). About 20% of men (284) were considered to have urinary problems. The mean urinary symptom score for all men was 0.9 (0.9–1.0). The mean total NIH-CPSI score for men reporting pain was 13.3 (12.0–14.7) and for all men it was 2.6 (2.3–2.8). The estimated prevalence of prostatitis-like symptoms was ≈2%.

CONCLUSIONS : Using the NIH-CPSI the estimated prevalence for urogenital pain in Australian men is 8%; an estimated 3% of men experience pain from more than one urogenital location. The estimated prevalence of prostatitis-like symptoms in Australian men is 2%. Almost a third of Australian men experiencing urogenital pain or prostatitis-like symptoms would be less than satisfied if this was to be ongoing for the rest of their life.
