The objective of this study is to show the effect of guide vane geometry on the performance. In order to overcome the disadvantages of vertical axis wind turbine, a straight-bladed vertical axis wind turbine （S-VAWT） with a directed guide vane row has been proposed and tested by the authors. According to previous studies, it was clarified that the performance of the turbine can be improved by means of the directed guide vane row. However, the guide vane geometry of S-VAWT has not been optimized so far. In order to clarify the effect of guide vanegeometry, the effects of setting angle and gap between rotor blade and guide vane on power coefticlent and start- ing characteristic were investigated in the experiments. The experimental study of the proposed wind turbine was carried out by a wind tunnel. The wind tunnel with a diameter of 1.8m is open jet type. The wind velocity is 8 m/s in the experiments. The rotor has three straight blades with a profile of NACA0018 and a chord length of 100 mm, a diameter of 0.6 m and a blade height of 0.7 m. The guide vane row consists of 3 arc plates.

Implementing effective cost management approaches has recently gained momentum due to intense competition and increasing customer demands. Moreover, effective cost management approaches have contributed to firms＇ competitive advantage in relation to cost leadership strategy. Consequently, firms have implemented contemporary cost management systems, such as activity-based management, business process re-engineering, life-cycle costing, target costing, and theory of constraint （TOC）, to enable them to become low-cost producers and compete effectively and sustain their performance. Furthermore, focusing on cost management to improve profitability has led to the integration of activity-based costing （ABC） and TOC. Therefore, the aim of this study is to review literature and discuss how integration of ABC and TOC can result in improved and sustained cost management. While these methods have different approaches in addressing cost management, treating them as complementary cost management approaches can result in improved cost management due to improved product costing, improved cost reporting, improved product-mix decisions, and improved cycle-time management. Improvement in cost management will then result in sustained cost management. Sustained cost management is further enhanced with the investment in information customer and shareholder value technology that supports cross-functional decision making to continue creating to remain competitive in the market.

Southwest Ghana is a major gold producing region. The current high gold price has attracted hundreds of unemployed youth to undertake small-scale mining (SSM). Most of these miners operate illegally even though the SSM law (PNDCL) 218 of 1989 and Act 703 of 2006 define the procedures required for their operation. Some miners have brought their activities to a segment of the western highway that links southwest to central Ghana with serious environmental consequences envisaged. This paper argues that the laws that regulate SSM do not consider the fundamental set-up and concerns of the small-scale miner, hence its inability to be effective. It is therefore proposed that the present requirement that a minimum of 21 hectares is necessary before land can be registered needs re-examination. Secondly, government needs to explore parcels of land and designate the workable areas to miners under a well structured scheme that will also educate these miners about safe and healthy mining methods.

This study seeks to explore the impact of the Environment Management Act （EMA）（2005） on the accountability of three companies in Fiji. The study uses a multi-case study approach based on three subsidiaries of a conglomerate. Data collection methods include semi-structured interviews with accountants, internal auditors, and environmental officers, document reviews, and content analysis of annual reports and websites of the respective companies. The findings suggest that the EMA （2005） had some effects in terms of engendering accountability on the companies studied. Further evidence suggests that while this increased accountability has led to disclosures in annual reports and websites, these disclosures are minimal at best; furthermore, they primarily address that the stakeholder group comprised government regulatory authorities. The study provides policy implications on how environmental legislations could be designed to improve the accountability of commercial entities in developing economies. The experience and issues highlighted are also useful to other developing economies who are contemplating in developing their own environmental legislations. This paper is one of the few papers that explore the impact of environmental legislations on accountability in a developing economy context.
