The purpose of this paper is to estimate the changes of dental caries status among Thai adults and elderly under the different policy options using system dynamics modeling.

A multi-sector system dynamics model was developed to capture the dynamic interrelationship between dental caries status changes and oral health behavior – including self-care, dental care utilization and sugar consumption. Data used to populate the model was obtained from the Thai national oral health survey in 2000, 2006, 2012 and Thailand Official Statistics Registration. Three policy scenarios were experimented in the model: health promotion policy, dental personnel policy and affordable dental care service policy.

Dental caries experiences among Thai adults and elderly were projected to increase from now to 2040, as the elderly population increases. Among all policies experimented herein, the combined policies of health promotion, increased affordability and capacity of dental health service were found to produce the highest improvement in dental caries status with 3.7 percent reduction of population with high decayed, missing and filled teeth (DMFT) and 5.2 percent increase in population with very low DMFT.

This study is the first comprehensive simulation model that attempts to explore the dynamic interrelationship among dental caries experiences and behavioral factors that impact on oral health outcomes. In addition, the simulation model herein offers a framework for policy experimentation that provides policymakers with additional insights to inform health policy planning.

The purpose of this paper is to present a dynamic macroeconomic framework that identifies the fundamental structure of public debt accumulation process in developing countries and its two way linkages with economic growth and public finances. Within this framework, the objective of this study is to identify leverage points that may be utilized to slow down debt accumulation process without slowing down economic growth.

The paper uses the system dynamics (SD) method to model and analyze the debt accumulation process. This method allows us to analyze the relationship between structure and behaviour of complex dynamic systems. This paper considers fiscal policy as the strategic element of the debt accumulation process and hence it considers seignorage and consequent inflation to be outside the model boundary. In other words the paper assumes that there exists an effective monetary policy that satisfies the objectives of the fiscal policy.

Capping debt servicing (debt relief) increases the debtor country's capacity to invest and the higher investment will raise capacity to pay debt in the future, with some of the rewards going to the creditor. Financing public investment through borrowing produces the highest Debt-GDP ratio compared to all other polices considered. Widening of the tax base to include this informal sector without increasing the tax rate and reducing the extravagant non-debt current expenditure are effective endogenous policy options that help reduce considerably the Debt-GDP ratio. The best composite policy demonstrates that a reduction in the Debt-GDP ratio does not only require exogenous assistance (debt relief) but endogenous government and private sector responsibility to maintain fiscal discipline and generate growth.

The unique characteristic of this model is the transparent way in which it represents the two-way feedback relationship between the debt, public finance and economic development taking into consideration the delays and non-linearities involved in this process.

This study aims to examine the moderating effect of supportive organisational culture (SOC) on the differential impact of work-based learning (WBL) on employee agility, ambidexterity and proactive goal generation.

A cross-sectional survey was conducted using an online structured questionnaire with 443 respondents in Ghana. The data set was analysed using structural equation modelling.

The outcomes of the study show that WBL has a significant and positive impact on employee agility, ambidexterity and proactive goal generation. However, the effect on employee agility was higher, followed by proactive goal generation and employee ambidexterity. The moderating effect of SOC on H1, H3a and H3b was found to have a decreasing effect.

This study augments knowledge by examining how different approaches to WBL collectively affect proactive goal generation, agility and ambidexterity. To the best of the authors’ knowledge, this is the first attempt to examine the differential impact of summative WBL approaches on employee outcomes.

The purpose of this paper is to investigate whether the characteristics of the audit committee (AC) chair affect audit report timeliness. In particular, the direct association between AC chair accounting expertise and audit report delay, and the moderating effect of other characteristics of AC chair on this association are examined.

To achieve the purpose of this study, the characteristics examined by this study are AC chair expertise, shareholding, tenure and multiple directorships. Furthermore, a sample of Malaysian companies during the period 2005–2011 and the fixed effects panel data method are utilized.

The results suggest that an AC chair with accounting expertise is associated with a reduction in audit delay. The reduction is more obvious when the chair holds shares in the company, but is weakened by longer tenure and multiple directorships. These results are robust after conducting several robust tests. Using mediating analysis, the authors also document that an AC chair with accounting expertise can enhance the timeliness of audit reports even when the quality of financial reporting is lower. The reported result is supported by additional analysis that finds that AC chairs with accounting expertise and AC chairs with accounting expertise and shareholding are significantly associated with shorter abnormal audit delay.

This study provides comprehensive analysis concerning the association between AC chair and audit report timeliness using a unique setting. It is among the limited evidence that reports the moderating effect of AC chair characteristics on the role of such chair on audit report timeliness.

The emergence of residential aged care facilities (RACFs) within the Ghanaian health-care system has raised eyebrows because, hitherto, the concept of nursing homes had largely been perceived as an anomaly. The purpose of this study is to understand this emerging phenomenon and the activities of care provided within two facilities in the nation’s capital, Accra.

The study draws on participant observations and in-depth interviews with purposively sampled 15 residents in the two facilities and eight caregivers. The data were analysed using thematic approach.

The study found that the daily forms of care mostly performed for the elderly were intimate and non-intimate physical, medical, emotional and spiritual and end-of-life care. The bulk of activities of care were performed in the morning.

The study reveals that the changing landscape of health-care facilities in Ghana to include RACFs indicates RACFs have come to stay to provide different forms of care to older persons who otherwise were cared for by the family.
