This is motivated by complex non-linear structure inherent in market integration processes, which is derived from multiple equilibria conditions, and transaction costs constrained threshold autoregressive (TAR) effects. These place theoretical limitations on current time series empirical models that are applied in market integration studies. In equilibrium representation, the non-linearities imposed by both alternating rent levels and switching adjustment parameters are directly accommodated. Two synthesized time series market data sets of varying levels of non-linear structures are used to highlight the strengths and limitations of the Markov variants vis-à-vis the band-TAR models that have currently dominated market integration analysis. The former model could capture alternating adjustment processes implied by the relatively complex non-linear market data set while the later produced mixed results. 2013-08-01T00:00:00Z http://41.74.91.244:8080/handle/123456789/4697 The Impact of TVET on Ghana’s socio-economic development: A aase study of ICCES TVET skills training in two regions of Ghana Pongo, N.A Integrated Community Centre for Employable Skills (ICCES) is an agency under the Ministry of Employment and Social Welfare with policy objective of filling the gap in employment generation by developing the young human resources in line with the poverty alleviation goal of the government of Ghana. The purpose of the study was to find out how the ICCES training programmes are achieving their purpose of increasing access of young person’s to skills acquisition and empowerment for productive employment. To harness the needed information, questionnaire, interview and observation, were employed in gathering data from the subjects. The results suggest that participants in the survey had all conferred that the programmes have being helpful to the communities in securing suitable employment that allows them to generate income within the social, family and financial constraints that they face in their communities and as such their social and economic status has being impacted positively. 2014-01-01T00:00:00Z http://41.74.91.244:8080/handle/123456789/621 Technical expertise development in secondary technical schools: Effects of ICT-enhanced 4C/ID learning environments Sarfo F.K.; Elen J. This study assessed the effectiveness of powerful learning environments (PLE), developed in line with the specifications of the 4C/ID-model, and the additional effect of ICT for fostering the development of technical expertise in traditional Ghanaian classrooms. The study had a one by one by two pretest posttest quasi experimental design. Three functionally equivalent classes of students from three similar (secondary technical) schools were randomly exposed to three different treatments. The participants consisted of 144 (44, 47, 53) students (mean age was 18.1). The pilot study, served to validate and revise the materials, and to retrain teachers. The main study, consisted of six sessions, conducted in regular classrooms of three schools to test the formulated hypotheses. The results indicate that a 4C/ID PLE promotes the development of technical expertise in secondary technical education better than teaching designed in line with classical instructional design principles. Moreover, results reveal no significant difference of learning gains between the 4C/ID PLE with ICT group and the 4C/ID PLE without ICT group. Finally, the theoretical, research, and practical implications of the results for the instructional design and technology community as well as educational practice are discussed. � 2006 IEEE.

This paper examines the current electrical generation expansion plan of Ghana and compares it with proposed expansion pathways with higher penetration of Renewable Energy Technologies. An adaptation of Schwartz's Scenario Methodology was used to develop the scenarios which were then analysed using the Long-range Alternatives Planning (LEAP) model. Each of the scenarios represents policy options for generation expansion in Ghana up to 2040. Energy, economic and environmental analysis of the three alternative scenarios compared to the base scenarios was undertaken. Sensitivity results show that, if the country were to follow the generation expansion path described in the renewable energy scenarios, it could reap economic benefits of 0.5�13.23% depending on the developments in fuel prices and renewable technology capital cost. The analysis further quantifies benefits to be derived from a reduction in Greenhouse gases of the scenarios. Policy implications for the generation system of Ghana based on the results are also discussed. � 2017 Elsevier Ltd Awopone, A.K., College of Engineering, Design and Physical Sciences, Brunel University London, Uxbridge, UB8 3PH, United Kingdom, College of Technology, University of Education, Winneba, P.
