Faruk Ahmeti
Abstract:
This study highlights the importance and explores the contributions of community capacity building (CCB) to achieving a sustainable tourism. Community capacity building is extensively recognized as a significant tourism development tool, which if implemented properly can contribute in community development and prosperity. In order to be able to create new successful strategies on building capacities of communities related to tourism, often is required to investigate existing problematic issues and to create a clear picture of the current state of community capacities and all related community capacities pertaining to tourism development in particular region. Community capacity building not only represents a step toward creating a sustainable tourism industry, but it is an essential ingredient for the overall development of the community. Tourism development and capacity building, within the communities where tourism is seen as a community opportunity, are closely linked and need to evolve and prosper simultaneously. It is important the fact that CCB programs help communities to increase their capability to contribute in the tourism decision-making processes, rather than being a spectator on its own playground. Especially the developing countries and regions, in particular rural and peripheral regions, benefit the most from the CCB. They inspire community participation in tourism development, and through CCB the communities gain the tools that empower them to do so. This paper attempts to examine the impact of the community capacity development in tourism development in transition countries.

Evaluation of Excellent Quality in Software Project Development Using Six-Sigma and Fuzzy Approach
551-562
Chandrakanth G Pujari and Seetharam.K
Abstract:
Six- Sigma is a skillfully planning tool of important value in achieving operational excellence. The choice of software project decision, under a resources constraint, is the early stage of execution for a Six-Sigma intervention. The choice of software project decision is challenging due to its fuzzy group decision-making aspect inherent to the problem. The present study proposes a hierarchical human criteria and sub-criteria evaluation process. The strategic criteria are evaluated by the software top management team using a fuzzy multiple criteria decision-making method. Then, the tactical human sub-criteria which contain additional operational issues are evaluated by the Six Sigma expert. The proposed methodology is applied in solving the choice of software project problem deriving from a software component developer. The empirical results are promising. Moreover, the results show that the higher a software project’s priority is, the greater the financial profits will be on end of the completion of the software project. Accordingly, the proposed methodology can prioritize the financial profit – which is the major performance for a Six Sigma software project. Additionally, the quality and reliability status of the case organization has been significantly improved through execution of the Six-Sigma software project. The evaluation process also influences software developers to adopt an analytical operations philosophy. The business objectives of the organization are brought into focus by the proposed methodology.

Role of Surface Complexation on the Magnetite Flotation
563-571
Hyonseung Dho
Abstract:
Micro and batch flotation test results showed that CMC depressed the hematitic ores, however, the poor selectivity was obtained for the magnetite. The iron oxides present present in the ores have zero point charge in the pH range of 6.5. Thus at a flotation pH of 8-9, the surface has a negative charge and adsorbs the cationic collector. Although zeta potential and adsorption measurements revealed that cationic chelating agents adsorbed magnetite effectively, the adsorptive characteristics was rather complicated to explain. When magnetite is in contact with chelating agents, several phenomena are expected during adsorption and dissolution processes; the dissolution of magnetite, surface chelation, and bulk chelation in the solution phase. From the surface complexation model, phen is the only adsorbing species for 1,10 phenanthroline. For 8-quinolinol, the neutural species and the negatively charged ion are present. The isoelectric point of magnetite was at pH 9.2 in the presence of 1,10 phenanthroline. The i.e.p of 8-quinolinol was pH 5.2. The adsorption mechanism of 8-quinolinol on magnetite was the formation of a negatively charged chelate in the magnetite /solution interface. The adsorption of the selected chelating agents was expected to depend on the combined effect of electrostatic forces.

An Empirical Investigation of Fiscal Policy Effects on Economic Growth in Ghana
572-588
Godfred M. Aawaar, Thomas Adomah Worae and Isaac Twenboah-Koduah
Abstract:
This study examines the effects of fiscal policy on economic growth in Ghana using time series data spanning the period 1981 – 2012. An endogenous model fashioned in line with the standard production function is specified for the analysis. Real GDP is regressed on a set of fiscal variables including government consumption expenditure, government investment expenditure, taxes, and transfer payment and non-fiscal variables including private investment, terms of trades and labour force. The Augmented Dicker-fuller (ADF) test for stationarity and the Autoregressive Distributed Lag (ARDL) model for cointegration test were applied in estimating the short-run dynamics and long-run effects of fiscal policy on economic growth. The empirical results suggest that all variables included in the model are integrated of order one I(1), and are stationary after the first differences at the 5% significance level. The study lends support of a long-run relationship between economic growth and fiscal variables. According to the results in this study (1) economic growth is positively and significantly affected by fiscal variables in the long run; (2) government investment expenditure, transfer payment, labour and private investment positively and significantly affect economic growth; while terms of trade positively but insignificantly affect economic growth; and (3) government consumption expenditure and taxes negatively and significantly affect economic growth. The study recommends the design and implementation of measures to widen the tax net rather than increasing taxes and reduce trade deficits in the country.

Optimization of Power Flows in an Electrical Power Transmission System
614-621
H. Mousavi, M. Mohseni and H. Jazayeri-Rad
Abstract:
A congestion management system is defined as a systematic method that starts from a part of the grid and then progresses to normalize the congested system. This can safely be accomplished through providing new transmission facilities. In this work, we try to consider some of the current aspects of the congestion management. A hybrid model of electricity market combined with the Benders technique which is an optimal power flow (OPF) problem solver are used to solve congestion in the grid. The Benders algorithm decomposes the main problem into a master problem and a sub-problem. The master problem concentrates on the economic aspects of the grid and the sub-problem solves the grid and accurately determines the respective conditions. The Benders algorithm is then tested on a standard 24-bus IEEE grid. The MATLAB software package is employed to implement the proposed algorithm.

Onah Gregory Ajima
Abstract:
The practice of Afiye (Caste System) among the Yala communities of Cross River State of Nigeria, settled in Yala Ogoja, Yala Obubra, and Yala Ikom, is an age long practice, which no one today can precisely point to its exact origin. The practice of Afiye and the Ayiwoole (slaves and freeborn), without considering the grave consequences, here analysed as implication of the system. The implication involves the political implication which tends to hinder the political rights of members of this caste, through its social structure. There is also the implication on Human Right, whereby members of this caste are denied freedom of association and movement. There is also social discrimination, which has equally affected their social standing in their different communities, such that they cannot be Ochuole (Traditional Rulers) or be allowed to participate in traditional burial rites of the traditional ruler that is regarded as the father of all. The economic factor is not left out as dispute bothering on land matters are usually and often settled in the palace and since they are the unwelcome species of human beings in the palace, there are left with no other opportunity than to be disempowered. Of course, there is the strained relationship and conflicts between the Ayiwoole and the Afiye, what Ralph Darendorf called the dialectical conflict theory. This has led to under development, Anger, bitterness and uncooperative attitude and indeed suspicion and all manners of negative tendencies among the Yala communities. It is the submission of this paper therefore, that the practice of this caste with its antecedent implications be put to a stop in order to bring about a meaningful development to Yala land.

Peyman Gholizadeh
Abstract:
Nowadays evaluation and comparison of Industrial Components Manufacturing Companies has become important due to ensuring effective selection of manufacturers. In this work, companies manufacturing internal and external industrial components are compared using a hierarchical fuzzy TOPSIS model. To this end, in the first step effective factors in comparison and evaluation process are extracted and then they are specified using expert ideas. In addition, data related to these criteria regarding manufacturing companies are extracted using questionnaire. Due to uncertainty in evaluation and comparison of manufacturing companies, a model is proposed based on MCDM and fuzzy concepts. Application of the proposed model has been suggested for a case study comparing 3 domestic and 2 foreign companies which manufacture industrial components mostly active in producing Oil and Gas components.
Keywords: Evaluation and comparison of companies, effective criteria in evaluation, industrial components and equipment, hierarchical fuzzy TOPSIS model.
