    The objective of this study is to investigate the effect of variation of the tube length and the crosshead velocity on the amount of energy absorption of aluminium tubes (Al 6061) towards the inversion collapsed mode. The tests were performed on the Aluminium tubes using compression test apparatus according to ASTM E8 standard procedures. Two parameters that are included in the experiment were the crosshead velocity and tube length. The collected experimental data were organized and analysis of energy absorption was performed. Comparison was made to the values of energy absorption obtained from the experiments, and it was found that the energy absorbed by the Aluminium tube was increased by increasing the tube length as well as crosshead velocity.

    The work conducted in this study is based on a preliminary data collection for assessing a soil status in a 5-year old Karas agroforestry plantations in Rembau, Negeri Sembilan, Malaysia. Three agroforestry components involved in this study include (1) Karas (Aquilaria malaccensis) monoculture, (2) Karas intercropped with lemongrass, and (3) Karas intercropped with guava. Three replicative plots measuring at 6 m × 5 m were established for each component. Each plot consists of a total of 90 Karas trees. The diameter at breast height (DBH) of Karas trees was measured in each plot. From the field measurements, the means of tree DBH in all three plots are 5.74 cm, 4.23 cm and 6.65 cm, respectively. Analysis of variance (ANOVA) revealed that there is a significant difference in the mean DBH of Karas tree between components (P≤0.05). Karas intercropped with guava recorded a significantly greater DBH than the other two components (P≤0.05). This could be due to the intercropping effects of Karas with different components of agroforestry system. The results from this study will be used for subsequent investigation in the assessments of growth performance of Karas under different intercropping components. View full abstract»

    Recreation ecology research was widely conducted to analyze data on factors that influence nature trails condition. Protected area such as Imbak Canyon Conservation Area (ICCA) was established because of its outstanding natural area and its potential of providing outdoor recreation experience to visitors. However, recreation use is also one of the major threats to protected areas. This study addresses the impact of recreation use by conducting a trail assessment exercise to several major trails in ICCA. The assessment of current trails condition will later be use as a benchmark for trail use in ICCA. This preliminary assessment shows that even with a very low number of usages during the expedition, there are evidences of potential threats to the trail conditions, visitors experience and natural condition of the area.

    This study examines the effects of Corporate Social Responsibility (CSR) activity as a business strategy towards creating value for the company. Using the annual reports of 242 Malaysian listed companies, this study investigates the effects of CSR disclosure and firm performance in 2006 and 2008. This study also examines the interaction effects of ownership structure on this relationship. Results of this study provide evidence that CSR activity has the propensity to impact significantly on a company's success. The insignificant results reported in relation to the interaction effects of family and government ownerships further corroborate the strategic importance of CSR activities and disclosure decisions by managers in Malaysia. Overall, findings in this study indicate that CSR activities can potentially lead to strong financial performance. In addition, it also provides regulatory bodies with enhanced understanding in their efforts to improve CSR activities and disclosures even in agency setting characterised with the existence of dominant owners.

    This study has provided empirical evidence where the corporate tax compliance does have a significant relationship with corporate governance mechanisms. The study covered the period of pre MCCG (Malaysian Code on Corporate Governance) revision (2005 to 2006) and post MCCG revision (2007 to 2008). The statistical results reveal that MCCG does influence a constructive impact on the level of corporate tax compliance in Malaysia. Although the efforts of establishing MCCG and strengthening the code by the MCCG revision in year 2007 was not embrace directly to increase the level of corporate tax compliance. But, this study has successfully provided empirical evidence where the corporate tax compliance does have a significant relationship with corporate governance mechanisms. The findings of this study will give another angle of deliberation to the corporate governance interests' as well as the corporate taxation. View full abstract»

    In earlier studies on co-movement of stock markets focused mainly on conventional equity markets. In contrast to previous studies, this research investigated on co-movement of Islamic equity markets. Emphasis was placed on two questions: do the Islamic stock markets in Asia and US move together and what will be the directions of the movements? The data are obtained from Morgan Stanley Capital International (MSCI) of daily indices of sixteen equity markets, for the period between August 2004 to December 2008. The study uses correlation analysis, Augmented Dickey Fuller, unit root test and Granger causality test. The results revealed: (1) more than half of the Islamic equity markets in Asia and US are significantly and positively correlated, implying there are potentials for diversification especially those markets that have low correlation values, (2) the unit root test indicated that Islamic equity markets are stationary, and (3) Granger causality indicated that 23 percent of the Islamic equity markets of Asia and US are bidirectional causality, 53 percent are unidirectional causality and 24 percent have showed no causality.

    The accuracy of financial time series forecasts often relies on the model precision and also the availability of actual observations for forecast evaluations. This study aims to tackle these issues in order to obtain a suitable asymmetric time-varying volatility model that outperformed the forecast evaluations based on interday and intraday data. First, the model precision is examined based on the most appropriate time-varying volatility representation under the autoregressive conditional heteroscedascity framework. Second, the forecast evaluations are conducted under three loss functions using the volatility proxies and realized volatility. Finally, the empirical studies are implemented on two major financial markets and the estimated results are applied in quantifying their market risks. View full abstract»

    The purpose of this paper is to measure the default probability of Malaysian companies which have issued Sukuk for the period 2001 to 2010 by using Merton's Model. Maximum Likelihood Estimation (MLE) method has been used in the computation of the unavailable parameters of the Merton's Model which are the market value of the company's asset, the volatility and the asset expected return. Findings show that Sukuk with high default risk earns higher returns than Sukuk with low default risk. The rating of the Sukuk supports the result of the default probability whereby most of the Sukuk with high probability of default were rated low. This study finds the default probability measured from Merton's Model can explain the credit ratings of the Sukuk. Ordered probit model has been used to examine the effectiveness of the market based model in explaining credit ratings as compared to the accounting based model. By incorporating Merton's default probability model with two other related default risk factors (issuer size and book-to-market ratio), the model is found to have outperformed accounting-based model in explaining Sukuk credit ratings.

    There have been number of studies discussing the optimal level of capital structure since the seminal work of Modigliani and Miller (1958). In this study, we examine whether an optimal level of debt exist at which a firm could maximize its value. An advanced panel threshold regression model by Hansen (1999) is employed to test the effect of debt ratio on the firm value among Malaysian listed firms from 2005 to 2009. The findings from this study show that additional debt beyond the threshold level does not add to a firm value. View full abstract»

    This study investigates the long-run and short-run movements of two emerging stock market volatilities using a volatility decomposition methodology. We studied the impact of 2007-2008 subprime mortgage crisis on the transitory and permanent volatility components in terms of two empirical stylized facts, the leverage effect and volatility persistence. In order to do so, the long spanning data are separated into three different periods. For the former stylized fact, the crisis impact on the leverage effect is mainly temporary with no long-run effect to the stock markets. This finding explains that the leverage effect is mostly difficult to adjust in the short-run transitory volatility during the crisis periods. However with proper risk management and long term strategies, most of the market participants are able to anticipate and handle this news impact in the long-run. For the latter stylized fact, the crisis has slightly increased the volatility persistence in all the markets. From the viewpoint of heterogeneous market hypothesis, the higher intensity of volatility persistence implies the stock markets are less informational efficient. View full abstract»

    On April 17, 1999, the Kuala Lumpur Stock Exchange, today known as Bursa Malaysia, launched a new index called Syariah Index (SI) to facilitate participation in the equity investment in accordance with Islamic syariah's principles. Syariah-based equity is basically shares of the company meeting the criteria of Islamic jurisprudence. Indices are used as a performance benchmark for portfolios such as mutual fund shares. The index is a device that allows investors to measure the performance of the group share of the market. This paper forecasts the FTSE Bursa Malaysia Hijrah Shariah (FBMHS) and FTSE Bursa Malaysia KLCI (FBMKLCI) index using the better model of Geometric Brownian motion in terms of volatility models and number of data. This paper shows that forecasting using log volatility and 4 week daily data gives accurate forecasting. View full abstract»

    The article presents an extensive experimental test and finite element simulation of plain 1/1 woven fabric subjected to uniaxial loading. Square woven fabric is configured to allow systematic investigation of weave effects under uniaxial tensile load. The geometric fabrics models consisting of warp and weft yarns are imported to finite element analysis package, ABAQUS, for mechanical performance simulation. Simulated and experimental stress-strain validation of plain is reported to have strong positive correlation of 0.9986 and 0.999 in warp and weft direction, respectively. Further analysis is performed on the validated models such as stress distribution groups and maximum stress regions. View full abstract»

    The paper gives an overview of current conceptual framework for the credit risk assessment dedicated to banks. The framework utilises the Merton model to estimate the default probabilities of companies that are supposed to be the main borrowers causing a formation of a greater credit risk in banks. By doing this, banks are able to reaffirm the ability of their borrowers in meeting loans commitments. Conceivably, it can facilitate the banking decision-making process and next complementing the existing instruments of credit risk mitigation. In the meantime, the paper compares the changes of values exist in company's asset and its volatility, company's drift rate and company's default probability if iterative procedure is applied in the framework. It is found that the values change in each variable is negligibly small to give much effect in predicting the credit risk. An example of Petra Perdana Berhad was done for the framework application.
