Conditional Beta Capital Asset Pricing Model (CAPM) and Duration Dependence Tests

This paper uses a sample of 50 companies continuously listed on Main Board of Bursa Malaysia from January 1994 until December 2001 and uses duration dependence tests whilst applying two asset pricing models based on the CAPM; the two Factor Model developed by Fama and French (F&F)(1998) and Ferson, Sarkissian and Simin's (FSS) (2008) conditional beta model applied to estimate the conditional beta of CAPM as to generate the positive and negative abnormal returns. The findings suggest that both the Log Logistic and Weibull hazard models seem to support the existence of negative duration dependence for both positive and negative runs of abnormal returns, consistent with the presence of bubbles theory as predicted by McQueen and Thorley (1994). The negative runs of abnormal returns for both the F&F and FSS models show that more than 80% of the sample seems to support the existence of negative duration dependence using both hazard models. Meanwhile the positive runs show that not more than 80% of the sample rejects the null hypothesis based on LR tests of the absence of duration dependence. Therefore, the analysis and results suggest that the negative runs of abnormal returns are consistent for both hazard models.Duration dependence, Two factor models, Rational bubbles, Log logistic and Weibull hazard models

Application Of Dynamic Correlation Technique And Model Updating On Truck Chassis

Truck chassis is a major component in a vehicle system. It is often identified for refinement in order to develop vehicles with reduced cost and weight. Nowadays the process of chassis design in the automotive industry has been significantly refined with the high capabilities of advanced computer aided design and engineering tools,. The application of FEA such as structural modification and optimization is used to reduce component complexity, weight and subsequently cost. Because the level of model complexity can be high, the opportunity for error can also be high. For this reason, some form of model verification is needed before design decisions made in the FEA environment can be implemented in production. This paper looks into the application of dynamic correlation techniques for verification of the FEA models of truck chassis. The dynamic characteristics of truck chassis such as the natural frequency and mode shape were determined using finite element method. Experimental modal analysis was carried out to validate the FE models. Initial results from both analysis show that the truck chassis experienced 1st torsion mode for 1st natural frequency, 1st bending mode for 2nd natural frequency, 2nd torsion mode for 3rd natural frequency and 2nd bending mode for 4th natural frequency. However there is a small discrepancy in terms of frequency. Thus, the model updating of truck chassis model was done by adjusting the selective properties such as Modulus Young and Poisson ratio in order to get better agreement in the natural frequency between both analysis. Finally, the modifications of the updated FE truck chassis model was suggested such as by considering adding the stiffener. The purpose is to reduce the vibration as well as to improve the strength of the truck chassis

Stock Returns and Equity Premium Evidence Using Dividend Price Ratios and Dividend Yields in Malaysia

The empirical findings of Goyal and Welch (2003) and Cochrane (2006) suggested that dividend yields and dividend ratios are robust predictors of annual stock returns and annual equity premia. However, Goyal and Welch (2003) asserted that many researchers considered dividend yields to be a good predictor for the equity premium before the 1990s but not after the 1990s. We apply these models to the Malaysian market. Our general findings suggest that the in-sample performances of the KLCI Malaysian datasets present similar results to those predicted by Goyal and Welch (2003, 2006). Meanwhile, the Mincer-Zarnowitz (1969) regression forecast tests for out of sample performances illustrate poor predictability of stock returns and equity premiums using both dividend price ratios and dividend yields. Cochrane (2006) suggested that if stock returns and dividend growth are not predictable, then price growth must be forecastable to bring the dividend yields back to equilibrium after any shock given that the dividend yields are stationary. We find that the growth of dividends is predictable using data deflated by changes in the consumer price index. Thus, the overall results suggest that both dividend price ratio and dividend yield models have significant effects though the dividend yield model is a superior predictor of stock returns and equity premiums in the Malaysian context.Dividend yields, Dividend price ratios, Stock returns, Equity premium, Asian financial crisis 1997

Kepemimpinan Multidimensi Kepala Madrasah Dari Perspektif Guru

THE MULTIDIMENSIONAL LEADERSHIP OF MADRASAH LEADER IN TEACHER'S PERSPECTIVE: The quality of the madrasa leadership has contributed greatly to the success of education in the school. As the leader of the organization/ educational institution, the main role of the madrasah leader is as a manager and an administrator. As an instructional leader, the main role of the madrasah leader is as an educator and a supervisor. This paper aims to explain how a madrasah leader performs his/her role in the leadership of madrasah in the four dimension of leaderships and its implications for the effectiveness of education in madrasah. A total of 120 teachers from 16 madrasah (MTs and MA) with varied backgrounds were involved in this study. With the Cronbach Alpha of the research instrument0.917, empirically the research revealed that madrasah leader role as an administrator dominated over the roles as a manager and supervisor which were relatively similar. Meanwhile, the role as an educator seemed to be very weak. This indicates that madrasah leaders need to enhance their role as instructional leaders as this has direct impacts on the establishment of conducive academic atmosphere at madrasah. Ideally, to achieve the optimized outcomes of education in madrasah, these four dimensions should be run in a balanced manner

Biomimetic bone-like apatite coating on anodised titanium in simulated body fluid under UV irradiation

Low temperature deposition techniques of bioceramics coatings are now being researched and developed to avoid deficiencies inherent in high temperature techniques. Biomimetic coatings are a solution-based method conducted at ambient temperature to deposit bioactive coatings on the surface. The current study aims to investigate the effect of ultraviolet (UV) irradiation on the coating of bone-like apatite on the anodised surface. High purity titanium foils were anodised with an applied voltage of 350 V, current density of 70 mA.cm-2 in mixture of 0.04 M β-glycerophosphate disodium salt pentahydrate (β-GP) and 0.4 M calcium acetate (CA) for 10 min. After anodic oxidation, UV light treatment was conducted in pH-adjusted distilled water for 12 h with ultraviolet light A (UVA) irradiation. Subsequently, the UV-treated anodised titanium foils were soaked in SBF for 7 days with/without UVA irradiation. After SBF immersion for 7 days, anodised titanium with combination of UV light treatment and UV irradiation during in vitro testing was fully covered by highly crystalline bone-like apatite at maximal thickness of 2.8 μm. This occurred mainly due to the formation of large amounts of Ti-OH groups which act as nucleation sites for bone-like apatite. This study also revealed that UV irradiation during in vitro testing is superior in promoting growth of bone-like apatite compared to UV light treatment. The suggested mechanism for bone-like apatite formation on anodised titanium under different UV irradiation conditions is illustrated in this article. The findings of this study indicated that biomimetic bone-like apatite coating with assistance of UV irradiation is an effective method in accelerating the formation of bone-like apatite
