    Investigating households attitude toward recycling of solid waste in Malaysia: a case study

    No full text
    This paper investigates householders’ attitudes to the recycling of solid wastes in one part of northern Malaysia, namely Alor Setar town, Kedah State. A postal questionnaire survey was administered to households in Alor Setar town in selected areas of high, middle and low incomes. 389 responses were obtained, a response rate of 86.4%. A personal interview with an official of the Municipal Council of Alor Setar was conducted in order to identify the current situation of solid waste recycling and household participation as well as obtaining views on the recycling campaigns carried out by the Malaysian government in 1993 and 2000. The paper indicates that participation in recycling of household waste relies on the level of awareness and understanding of recycling. Improved education and increasing the accessibility of recycling facilities are the best means of promoting positive attitudes to recycling attitude, partly because they help to remove barriers preventing households from recycling. Households in Alor Setor town have identified some of the effective strategies that can be initiated by the government to increase the rate of recycling in Malaysia which would also encourage them to participate in recycling. One of these strategies was providing recycling bins in every residential area.

    No full text
    Conventional wisdom on what are sound marketing principles derives from the era when marketing came to prominence fifty years ago. A question is posed on each of eight core principles and practices of marketing and what might be the typical marketer's answer is shown to be only half right. The final section gives the course of action that companies and marketers should take to enable their marketing decisions to be based on up-to-date and useful knowledge on these important marketing practices.

    Backstepping controller design for a class of stochastic nonlinear systems with Markovian switching

    No full text
    A more general class of stochastic nonlinear systems with irreducible homogenous Markovian switching are considered in this paper. As preliminaries, the stability criteria and the existence theorem of strong solutions are first presented by using the inequality of mathematic expectation of a Lyapunov function. The state-feedback controller is designed by regarding Markovian switching as constant such that the closed-loop system has a unique solution, and the equilibrium is asymptotically stable in probability in the large. The output-feedback controller is designed based on a quadratic-plus-quartic-form Lyapunov function such that the closed-loop system has a unique solution with the equilibrium being asymptotically stable in probability in the large in the unbiased case and has a unique bounded-in-probability solution in the biased case.
