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.

Cultural, tourism, and creative industries sectors can be understood as having intersecting policy agendas and economic interdependencies. In the developing context the first two have a somewhat longer history of analysis than the last one. However, emerging studies are beginning to emphasise all three domains are interconnected to each other, and need each other to sustain their products in the market. However, the studies are mainly concentrated on Western countries and there are still many aspects of this concept remain unanswered particularly in developing nations for example Malaysia. Data on developing nations is still problematic and considerably limited, or only concentrated in countries such as China and India. To have a better grasp about the underlying key concepts of the development issues on creativity, technology and innovation applied in cultural products in developing nations this study proposed case studies approach to be applied in Malaysia. The creative economy development issues in Malaysia will be the primary focus to be investigated by this research. An electronic research through the Internet on two different case studies in Malaysia had been looked at on their experience in developing their creative economy through a combination between culture, tourism and creativity.

As a rapid developing country, many Malaysian citizens are currently living in the fast paced of life. This way of life has developed a trend of eating out in various restaurants and food stalls due to lack of time for food preparations. This trend has contributed to the booming of the food serving industry businesses and has created mass vacancies for employment. However, these employment vacancies are occupied by foreign workers. This paper is intends to (1) examine the relationship between contributing factors with employers dependency towards foreign workers and lastly (2) analyze the effects of contributing factors towards employers dependency on foreign workers. There are four variables used in this research namely government laws and regulations, attitudes of workers, availability of local workers and wages and incentive. Here, this study is applying correlation and regression to analyze the data. The findings show that all variables are associated with employers' dependency towards foreign workers. Lack of law and regulation enforcement is the most significant predictor that influences employers' dependencies towards foreign workers.

Aluminum nitride (AlN) and high aluminum (Al) content aluminum gallium nitride (AlGaN) thin films were successfully grown on gallium nitride (GaN) layer by plasma-assisted molecular beam epitaxy (PA-MBE) system. The films were deposited on Si 111 substrate. A systematic study and optimization of the growth conditions was performed in order to grow AlN and AlGaN layers on GaN films. Epitaxial growth of GaN has been demonstrated to be feasible for substrate temperature (800°C and 850°C) which depends on a Ga/nitrogen flux ratio. The absence of cubic phase GaN buffer layer for both samples has shown that this layer possessed hexagonal structure. The AlN sample has a good optical quality as measured by the photoluminescence (PL) system.

Thermal condition is a decisive factor which impacts the use of outdoor spaces. Concerns on outdoor thermal conditions are on the rise judging by the growing number of research on the subject. However empirical research in the context of urban outdoor in moderate and dry climate is still limited. Predicting thermal comfort of outdoor spaces in a particular setting is essential to ensure continuous return of visitors and users. This paper aims to establish the thermal acceptable temperature range applicable for an urban context in temperate and dry climate zone based on the physiologically equivalent temperature (PET) index. Two fieldwork experiments were conducted through environmental measurements and questionnaire survey performed in winter of 2009 and summer of 2010 at a public square in Esfahan, Iran. These data were used for the thermal comfort assessment, supported by the RayMan model for the calculation of the mean radiant temperature (Tmrt) and PET. The study established the acceptable thermal comfort range to be between 12.3 and 30.9 deg C which is relatively wider then past studies.

This preliminary study is a part of data collection for the development of the prediction model for the estimation of oil palm above ground biomass (AGB) and stem volume using remote sensing data. Oil palm agricultural tree crops have been extensively studied in the aspect of botanical and cultivation due to its socio-economic and commercial values. Malaysia is known as the world's top producers of palm oil with current planted area of plantations around 4.69 million ha. There is an abundance potential of biomass and renewable energy resources including oil palm in Malaysia. Oil palm residues are the major potential for power generation amounting to about 2400 mega watt. It has been acknowledged that renewable energy could be a key driver in maintaining the balance of economic development that would be anticipated to grow alongside the exponential rise of the global human population and climate change. Despite the importance of oil palm to the country, an accurate and reliable assessment method in resource availability is lacking. Therefore, the need for current inventory on oil palm biomass and stand volume leads this research into ground-based survey using the existing allometric equations. The objectives for this preliminary study are (1) to estimate AGB and stem volume of oil palm plantations of different ages and (2) to study the relationships between oil palm biomass and stem volume with the age of oil palm

The problem of location of protective devices is important in distribution networks so the various methods were considered for installation of fuse, recloser, disconnecting switch and breaker. In these methods, a set of protection, economic and reliability aspects are considered. Because of various goals, the optimal approach from some intelligent methods such as genetic algorithm does not get the best approach. At this condition, using mathematic methods is reasonable because they satisfy the best and the optimal approach. Binary programming method is one of these mathematic optimization methods that its speed is high. The problem of location of protective devices is naturally binary in distribution networks. This specification causes using binary programming method for optimal location of protective devices. In this analysis, the binary programming method is implemented for optimal location of protective devices installation in distribution networks. The optimization objective function includes the switching procedure cost and protective devices lifetime cost. Furthermore, the SAIFI and SAIDI analyses beside optimal approaches are calculated. The programmer with reliability consideration easily can choose the optimal possible approach. The proposed method make easy to obtain the best approach with protection consideration and etc. To analyze proposed method, a test network is considered. At a distribution network, the breaker is located in the beginning of the network so the simulation result can be extended to obtain the optimal location for recloser, fuse and disconnecting switch. The proposed method is obtained from Visual Studio C# .NET software.
配电网中保护装置的位置问题十分重要，因此对熔断器、重合闸、断开开关和断路器的安装方法进行了多种考虑。在这些方法中，综合考虑了保护、经济和可靠性三个方面。由于目标的不同，一些智能方法如遗传算法的最优解不能得到最优解。在这种情况下，使用数学方法是合理的，因为它们满足最优和最优方法。二进制规划法是其中一种速度较快的数学优化方法。配电网中保护装置的定位问题自然是一个二元问题。本规范规定使用二进制编程方法对保护装置进行最佳定位。在分析中，采用二进制规划方法求解配电网保护装置的最优安装位置。优化目标函数包括切换过程成本和保护装置寿命成本。此外，还计算了最优方法之外的SAIFI和SAIDI分析。考虑可靠性的程序员可以很容易地选择最优的可能方法。该方法便于在考虑保护等因素的情况下获得最佳方法。为了分析所提出的方法，我们考虑了一个测试网络。在配电网中，断路器位于网络的起始位置，因此可以扩展仿真结果以获得重合闸、熔断器和断开开关的最优位置。所提出的方法是在Visual Studio c# . net软件中实现的。
