Sustainable consumption: the effects of knowledge,cultural values,environmental advertising,and demographics

As a result of human lifestyles and unsustainable consumption patterns, the environment continues to deteriorate and thus inhibit sustainable development. In order to curb this situation and promote a sustainable economy, one of the solution is to reduce conventional products consumption and shift to green products. Over the past 20 years, marketing managers keenly seek to understand the green market; however, inadequate information on how to promote consumers’ green behavioral intentions is slowing the growth of green markets and becomes a barrier for firms when developing segments and communicating strategies for effective promotion of green products in countries like Malaysia where the trend is fairly new. Therefore, this study attempts to examine the impact of environmental knowledge, cultural values, and environmental advertising and determine the moderating effect of income level, education level, and gender on consumers’ green purchase intentions. A survey was administered, and a total of 405 valid questionnaires were obtained. Structural equation modeling technique was used to evaluate the causal model by using SmartPLS 2.0 software. The finding results suggest that cultural values and environmental advertising are the main influences in building green purchase intentions, while environmental knowledge is not significantly related. The results also indicate that education level and gender have a significant positive moderation effect while income did not. This suggests that green purchase intentions’ motivational factors are greater among highly educated individuals, with females in particular. The discussions and implications of these findings are further elaborated.     

Effect of cobalt-supplemented diets on bioaccumulation,digestive enzyme activities and growth of Cyprinus carpio

Experiments were conducted to determine the effects of excess dietary cobalt (Co) on bioaccumulation, digestive enzyme activities, and growth in freshwater Cyprinus carpio. Four isonitrogenous diets (average crude protein: 35%) were formulated to prepare a control diet (T₁) with no Co, and three Co-supplemented diets with 1 (T₂), 1.5 (T₃), or 2 (T₄)% Co. The results showed that C. carpio fed with T₃ diet showed maximal apparent protein digestibility, feed conversion, protein utilization, and growth. Protease and lipase activities were maximal in the fish group given T₃ diet. Accumulation of Co in different soft and hard tissues of fish did not correlate with levels of Co in the diet. The concentration of Co in the water increased with dietary level, being at a disturbing adverse effect level at 2% dietary Co. Evidence indicates that an additional supply of dietary Co up to a level of 1.5% is a viable option to augment growth of C. carpio, but at higher levels of Co it may be detrimental to fish health and the aquatic ecosystem.
