On behavior of the fifth algebraic transfer

In this paper, we show that Singer's fifth transfer is not an epimorphism in degree 11. More precisely, it does not detect the element P(h_2) in Ext_A^{5,16}(F_2,F_2).Comment: This is the version published by Geometry & Topology Monographs on 14 November 200

Greening hotels: does motivating hotel employees promote in-role green performance? The role of culture

In the new global economy, environmentally friendly policies have become a central issue for firms. The increasing attention given to the benefits of those policies has prompted research on the development of environmental management systems that encourage employees to engage in environmental activities. However, there is limited evidence concerning the relationship between employee motivation and employees’ in-role green performance, in addition to the potential impact of culture and organizational citizenship behavior for the environment. Through a quantitative study of 301 managerial and non-managerial employees working in three- to five-star hotels, this study makes a major contribution by demonstrating that practices aimed at motivating hotel employees (e.g. green reward and performance management) are significantly linked with employees’ in-role green performance and organizational citizenship behavior for the environment. The findings also indicate that the influence of green rewards on employees’ in-role green performance and organizational citizenship behaviors for the environment is stronger when hotels are managed by Western corporations. Conversely, the study showed that the effect of green performance management on these two dependent variables is not moderated by culture. This article supports efforts to widen national cultural perspectives in the development and application of green human resource management

The Vietnamese shrimp trade: livelihoods analysis of stakeholders and market chain analysis

Aquaculture and capture fisheries in Vietnam have been increasing fast in the last decade, especially aquaculture growth rate is 12% for the 1999 – 2003 period, contributing a significant part into the hunger eradication and poverty reduction1. Vietnam is to be ranked into one of the countries potential to produce the aquatic economic in the world, and the fact is that, after 40 years of establishing, the fisheries sector has made remarkable contributions to the country. By the list, at the moment the aquatic products make up about 4 - 5% of GDP and create job opportunities for over 3 three million employees (VASEP, 2004), in which the largest contribution is from shrimp farming.

Application of fruit juice for proliferation of Bacillus to control fungal phytopathogens

Plant-based media have recently been of interest as potential natural media for microbial culture. This study was conducted to apply inexpensive and available fruits to culture Bacillus antagonizing three fungal phytopathogens including Phytophthora capsici GTC 2.6.1, Rhizoctonia solani GTC 2.7.1, and Sclerotium rolfsii GTC 2.9.1. The results showed that the juice media of dragon fruit, Cavendish banana, watermelon, pineapple, and MT1 seedless guava could all be used to culture two screened antagonistic Bacillus strains including B08 and B18. Surveys on the media from watermelon juice indicated that juice concentration (based on mass of fruit pulp), initial pH, concentration of traditional medium added to the juice medium had different effects on the growth of two strains of Bacillus sp. B08 and B18. These preliminary results demonstrated the potential application of the juice in biomass production of antagonistic Bacillus strains. This approach is certainly safe for the environment and has the potential to improve fruit consumption and reduce the cost of microbial fertilizer production, so it needs more research attention
