Cultural Influences on Choosing Green Products: An Empirical Study in MALAYSIA

Abstract: Over the past few years, there have been increasing efforts to promote green products in developing nations. However, evaluating customer preferences when it comes to choosing green products is a rather complex task, which is perhaps due to the influence of cultural values on customer preferences. Hence, the objective of this study is to examine the influence of cultural value dimensions on customer preferences for green products in Malaysia. The sample consists of 615 Malaysian citizens and the data were analysed using the structural modelling approach. Based on the results, there are three cultural value dimensions that have a significant influence on customer preferences for green products in Malaysia: (1) uncertainty avoidance, (2) long-term orientation and (3) power distance. The implications of this study and recommendations for public policy and business orientation are also discussed in this paper in order to accelerate the attainment of sustainable development.

A review of the mechanisms of oral tolerance and immunotherapy.

Abstract: The induction of oral tolerance by oral immunization has been well recognized. Accumulated evidence shows that oral tolerance can be mediated by orally activated humoral and cellular factors. In animal models, the development of several T cell-mediated autoimmune diseases, such as multiple sclerosis, rheumatoid arthritis, uveitis and diabetes type 1 can be inhibited by oral immunization of the respective antigens. In allergy, oral administration of certain allergens can prevent and reduce both contact and atopic dermatitis. Oral tolerance to alloantigen also reduces graft rejection. In spite of these encouraging results, the usefulness of this approach for an alternative immunotherapy in humans needs to be investigated further.

Flashover from surface charge distribution on alumina insulators in vacuum

Abstract: Surface charge distributions of disk type aluminas held between a backside electrode (alumina holder) and a needle electrode to be excited by an impulse voltage (rise time 64 /spl mu/s, wave tail 700 /spl mu/s) were measured. The measurement of surface charge distribution on the whole surface area of alumina YSA998 and UHA99 after impulse voltage application revealed that the surface charging can be initiated either from the anode or from the cathode triple junction. The charging initiated from the anode triple junction (for positive polarity) produced positive charge at the anode region and the density is dependent on the applied voltage, while the charging initiated from the cathode triple junction region (for negative polarity) produced negative charge around the cathode region. For positive polarity, the critical values of charge density to the flashover for alumina YSA998 and UHA98 are 5.70 and 17.2 /spl mu/C/m/sup 2/, respectively.

Nitrate in drinking water and risk of colorectal cancer in Yogyakarta, Indonesia

Abstract: Nitrate concentration in well water in Yogyakarta, Indonesia, and its surroundings tended to increase rapidly from time to time, and it may be associated with an elevated risk for several types of cancer. The purpose of this study was to examine the association between nitrate in drinking water and colorectal cancer (CRC) risk occurrence. A case-control study was conducted in Yogyakarta Special Province. Pathologically confirmed 75 CRC patients and 75 controls were consulted and their individual well water was sampled and examined for nitrate concentrations. Logistic regression analysis was conducted to establish the association between nitrate and CRC risk development. There was a significant correlation between nitrate in drinking water and CRC occurrence, and this value was relatively stable after being adjusted for protein intake, smoking history, age, and family history of cancer. These findings demonstrated that the risk of CRC development was fourfold among those with >10 years of nitrate exposure from well water compared with those with ≤10 years of nitrate exposure. Consequently, a significant association between nitrate in drinking water and occurrence of CRC in Yogyakarta was established.
