Procedural trained, procedural remain : the first report from 'A census of doctors who have been awarded the Graduate Diploma in Rural General Practice (GDRGP)'

Aims & rationale/Objectives : To document the practice of initial cohorts receiving the Graduate Diploma in Rural General Practice
Methods : With the co-operation of the National Rural Faculty (NRF) of Royal Australian College of General Practitioners (RACGP), a census by questionnaire was conducted on 279 graduates. The response rate was 70%.
Principal findings : The target doctors are young (65% < 40 years old). Under half (42.3%) have completed Advanced Rural Skills terms in >1 discipline. Of the total 272 posts recorded from 174 respondents, the most popular advanced skill is anaesthetics, followed by obstetrics. The ARSP increased confidence in 96.3% of respondents. Two thirds of doctors trained in a procedural skill remain practicing procedural General Practice.
Discussion : The GDRGP was the qualification developed to recognise competency gained as a result of a series of rural training initiatives begun within the RACGP Training Program in 1992. Its delivery has continued under the new GPET Training Program. Outcomes from the range of initiatives leading to the GDRGP are currently emerging in an environment which has seen significant changes within vocational training, and within the context of a rising focus on indemnity. Doctors who undertook this training have mostly retained procedural practice. In addition, RACGP rural initiatives successfully achieved increase confidence prior to rural work in advanced areas of practice, with >95% reporting an increase.
Implications : Changes within vocational training were accelerated without analysis of existing initiatives such as the GDRGP. Funding for the GDRGP was, as a result, withdrawn prematurely. These changes also saw the entrant of a second College with an interest in rural procedural practice. This research show that the GDRGP offers, and offered, a clear vocational pathway that will guide a doctor to a career as a rural doctor, and provide them with the advanced skills they need to practice confidently in the bush. It is important to capitalise on past success before deconstructing professional concepts of practice further.

Testing the psychometric properties of Clary's volunteer motivation scale with online panel members

Academic researchers, industry and policy-makers are increasingly using online panels as a means for data collection for their research. Online panels are frequently constituted by volunteers who can choose to accept offers to participate in research (cf. voluntary opt-in Cooper 2000). This research focuses on the importance volunteering as the primary reason as to why individuals decide to become panel members. In so doing, we tested the psychometric properties of Clary et al. 's (1998) Volunteer Functions Inventory (VFI) making use of confirmatory factor analyses and ascertained that the dimensions exhibit adequate levels of reliability and validity in an online panel member's milieu.

External monitoring, managerial ownership and form performance in Malaysian capital market: a GMM based panel data approach

This study re-examines whether the structure of share ownership by both directors and institutional ownership provides explanation for firm performances. These relationships are modelled and estimated using GMM based dynamic panel data over a period from 1997 to 2001 with a sample of 100 CI components companies listed on Main Board of Malaysia. The findings provide strong evidence of simultaneity between firm performance and managerial ownership. Although an insignificant relationship between firm performance and institutional ownership is~ observed, the institutional holdings provide strong substitute for managerial ownership with a strong negative relationship between managerial ownership and institutional ownership. This is in line with the managerial incentive hypothesis, which suggests that manager's share in the firm's ownership leads to better performance and the monitoring substitute hypothesis, which suggests that managerial ownership could be effectively replaced by institutional ownership.

Energy consumption and real GDP in G7 countries : new evidence from panel cointegration with structural breaks

This paper examines the relationship between capital formation, energy consumption and real GDP in a panel of G7 countries using panel unit root, panel cointegration, Granger causality and long-run structural estimation. We find that capital formation, energy consumption and real GDP are cointegrated and that capital formation and energy consumption Granger cause real GDP positively in the long run. We find that a 1% increase in energy consumption increases real GDP by 0.12–0.39%, while a 1% increase in capital formation increases real GDP by 0.1–0.28%.

Are oil shocks permanent or temporary? panel data evidence from crude oil and NGL production in 60 countries

This paper examines the unit root properties of crude oil production for 60 countries employing a range of panel data unit root tests for the period 1971 to 2003. The study first employs a number of panel data tests that do not accommodate structural breaks and then proceeds to apply the Lagrange Multiplier (LM) panel unit root test with one structural break. The results of the panel data tests without a structural break are inconclusive with at best mixed support for joint stationarity. The findings from the LM panel unit root test with a structural break, however, are conclusive, suggesting that for a world panel and smaller regional-based panels, crude oil and NGL production are jointly stationary.

Evidence of panel stationarity from Chinese provincial and regional income

The aim of this paper is to examine whether Chinese provincial and regional real GDP and per capita real GDP are panel stationary for the period 1952–2003. We allow for multiple structural breaks based on a technique developed by Carrion-i-Silvestre et al. [Carrion-i-Silvestre, J. L., Barrio-Castro, T, D., & Lopez-Bazo, E. (2005). Breaking the panels: An application to the GDP per capita. Econometrics Journal, 8, 159–175]. Allowing for at most five structural breaks, we find that for 67% of the provinces, per capita real GDP is stationary; while we only find stationarity of real GDP for 17% of the provinces. However, when we extend the analysis to panel data models, we find statistically strong evidence of panel stationarity of Chinese provincial and regional income.

Do shocks to G7 stock prices have a permanent effect? : evidence from panel unit root tests with structural change

There is a plethora of studies that investigate evidence for the behaviour of stock prices using univariate techniques for unit roots. Whether or not stock prices are characterised by a unit root have implications for the efficient market hypothesis, which asserts that returns of a stock market are unpredictable from previous price changes. The extant literature has found mixed evidence on the integrational properties of stock prices. In this paper, for the first time, we provide evidence on the unit root hypothesis for G7 stock price indices using the Lagrangian multiplier panel unit root test that allows for structural breaks. Our main finding is that stock prices are stationary processes, inconsistent with the efficient market hypothesis.

Does environmental quality influence health expenditures? empirical evidence from a panel of selected OECD countries

In this paper we examine the role of environmental quality in determining per capita health expenditures. We take a panel cointegration approach in order to explore the possibility of estimating both short-run and long-run impacts of environmental quality. Our empirical analysis is based on eight OECD countries, namely Austria, Denmark, Iceland, Ireland, Norway, Spain, Switzerland, and the UK for the period 1980–1999. We find that per capita health expenditure, per capita income, carbon monoxide emissions, sulphur oxide emissions and nitrogen oxide emissions are panel cointegrated. While short-run elasticities reveal that income and carbon monoxide emissions exert a statistically significant positive effect on health expenditures, in the long-run in addition to income and carbon monoxide, we find that sulphur oxide emissions have a statistically significant positive impact on health expenditures.

Biometric, nutritional and sensory changes in intensively farmed Murray cod (Maccullochella peelii peelii, Mitchell) following different purging times

A period of purging before harvesting is common practice in intensive aquaculture to eliminate any possible off flavours from the fish. The present study was conducted to evaluate the biometrical, nutritional and sensory changes in intensively farmed Murray cod (Maccullochella peelii peelii) after 0, 2 and 4 weeks of purging. After the main biometric parameters were recorded, fish were analysed for proximate, fatty acid composition and flavour volatile compounds. A consumer preference test (triangle test) was also conducted to identify sensorial differences that may affect the consumer acceptability of the product.

Fish purged for 2 and 4 weeks had a significant weight loss of 4.1% and 9.1%, respectively, compared to unpurged fish, whilst perivisceral fat content did not change. The concentration of saturated (SFA), monounsaturated (MUFA) and highly unsaturated (HUFA) fatty acids were not significantly affected by purging time, while polyunsaturated fatty acids (PUFA), n − 3 and n − 3 HUFA were significantly higher (P < 0.05) in purged fish compared to unpurged fish. Consumers were able to detect differences between the purged and unpurged fish (P < 0.05) preferring the taste of the purged fish. However, consumers were unable to distinguish between fish purged for 2 and 4 weeks.

This study showed that a 2 weeks purging period was necessary and sufficient to ameliorate the final organoleptic quality of farmed Murray cod. With such a strategy the nutritional qualities of edible flesh are improved while the unavoidable body weight loss is limited.

The effect of using trained versus untrained adult respondents in simulated practice interviews about child abuse

Objective
A single study tested the hypothesis that simulated practice interviews for investigative interviewers of children are more effective when the role of the child respondent is played by trained actors (i.e., postgraduate psychology students) than untrained fellow participants (i.e., child protection workers).
Method
The interviewers included 50 child protection service workers. Each interviewer received instruction in the use of open-ended questions and then engaged in two simulated practice interviews. The role of the child respondent in the practice interviews was played by either a trained psychology student or an untrained fellow participant. The key outcome measure was the proportion of open-ended questions, which was assessed immediately prior to and after the practice sessions, as well as 12 weeks post-training.
Results
Interviewers who had practiced with trained actors had higher post-training performance (M = .83, SD = .12) compared to those who had practiced with untrained fellow participants (M = .73, SD = .13, p < .05), even at the 12-week follow up (M actors = .66, SD = .25; M untrained actors = .49, SD = .23, p < .05).
Conclusions
Training programs that make better use of practice opportunities (e.g., by using trained respondents) will be more effective in improving the performance of investigative interviewers.
Practice implications
A single study investigated the relative effectiveness of two simulated practice exercises for professionals who interview children about abuse. This research is relevant to professionals who design investigative interviewer training programs because it indicates that practical exercises, which are currently chosen on an ‘ad hoc’ or convenience basis, can vary markedly in their effectiveness in encouraging adherence to open questions.

Extruded products with Fenugreek (Trigonella foenum-graecium) chickpea and rice: Physical properties, sensory acceptability and glycaemic index

The present study investigated the effects of fenugreek flour (Trigonella foenum-graecum) and debittered fenugreek polysaccharide (FenuLife^®) inclusion on the physical and sensory quality characteristics, and glycaemic index (GI) of chickpea–rice based extruded products. Based on preliminary evaluation with different proportions of chick pea and rice, a blend of 70:30 chickpea and rice was chosen as the control for further studies. The control blend, replaced with fenugreek flour at 2%, 5% and 10%, or fenugreek polysaccharide at 5%, 10%, 15% and 20%, was extruded at the optimum processing conditions as specified in the detailed study. The extruded products were evaluated for their physical (moisture retention, expansion, hardness, water solubility index (WSI) and water absorption index (WAI)), sensory (flavor, texture, color and overall acceptability) characteristics and in vitro GI to evaluate their suitability as extruded snack products.

Due to the distinct bitter taste, inclusion of fenugreek flour was not acceptable at levels more than 2% in extruded chickpea based products. Addition of fenugreek polysaccharide resulted in slight reduction in radial expansion (P < 0.05), while longitudinal expansion increased. WAI increased while WSI decreased compared to the control (P < 0.05). The mean scores of sensory evaluation indicated that all products containing fenugreek polysaccharide up to 15% were within the acceptable range. There were no significant differences (P > 0.05) between products containing 5–15% fenugreek polysaccharide in their color, flavor, texture and overall quality.

Fenugreek, in the form of debittered polysaccharide (FenuLife^®) could be incorporated up to a level of 15% in a chickpea–rice blend to develop snack products of acceptable physical and sensory properties with low GI Index.

Examining the behaviour of visitor arrivals to Australia from twenty different countries : an application of panel unit root tests

Testing for the behaviour of visitor arrivals has important implications for policy, for if visitor arrivals are stationary processes then it implies that shocks to visitor arrivals are transitory. However, if visitor arrivals are found to be characterised by a unit root then this implies that shocks to visitor arrivals are permanent. In this paper we provide the first evidence on the unit root hypothesis for visitor arrivals to Australia using a suite of recently developed panel unit root tests. Our main finding is that visitor arrivals to Australia from twenty tourist source markets and from the G7 markets are mean reverting. implying that any shocks will have only a transitory effect. However; visitor arrivals from eight Asian countries are characterised by a unit root. implying that shocks will have a permanent effect on this market.
