Conceptualising risk culture on enterprise risk management (ERM) implementation in construction companies / Wong Ching Ching ... [et al.]

In today's global economy, inadequate risk management and lack of risk culture can threaten a company’s viability. Since construction industry is subjected to uncertainty, construction Public Listed Companies (PLCs) need to implement Enterprise Risk Management (ERM) as an effective technique in managing risk holistically. Although the importance of ERM is widely accepted, the influence of risk culture in its’ implementation is unexplored. This paper presents a conceptual model that shows the relationship between risk culture and ERM implementation. The dependent variable is ERM implementation, consist of four dimensions namely risk identification and risk assessment; risk treatment; monitor and consult; communicate and consult. The independent variables, risk culture compromise of six dimensions, which are risk policy and risk appetite; key risk indicators; accountability; incentives; risk language and internal relationships. This study aims to empirically test the relationship between risk culture and ERM implementation among Malaysian construction public listed companies. Quantitative method through questionnaire survey is adopted as data collection for this study. Risk culture is expected to have direct effects and significantly influence ERM. This study contributes to enhance the body of knowledge in ERM especially in understanding significant of risk culture that influence its’ implementation from Malaysian perspective

Effect of Sintering Cycle on Physical and Mechanical Properties of Open Pore Cell Copper Foam

AbstractPoor thermal management leads to high LED junction temperature and give negative impacts to its life and performance. High temperature of LED junction has proven to produce less light and accelerate chip degeneration. Open pore cell copper foam provide good solution to the poor thermal management problem since it has higher surface area, thus increase surface emissivity and enhance thermal conductivity. In this study, copper foams were fabricated using metal injection moulding using potassium carbonate as space holder. The effect of sintering cycle on physical and mechanical properties were studied using two different sintering cycle which are 450-850°C and 450-850-950°C. It is found that sintered copper foams using 450°C-850-950°C sintering cycle has better mechanical properties in term of hardness and transverse rupture strength. It also exhibited higher porosity which is up to 33.9% compared to 33.1%, thus has higher surface area. This is proven by higher thermal conductivity exhibit by the specimen sintered using 450°C-850-950°C
