Measuring Market Potential for Fresh Organic Fruit and Vegetable in Ghana

This paper examines the market potential for fresh organic lettuce and water melon with a recently collected data on consumers from Kumasi metropolis of Ghana. Using a doublebounded dichotomous choice contingent valuation technique, consumer’s willingness to pay is estimated with a Tobit model to address the zero willingness to pay responses in the sample data. As much as 71% of the consumers are willing to pay over 50% price premiums for organic vegetables and over 82% are willing to pay 1%–50% price premiums for organic fruits. The empirical results indicate that human capital, product attributes and consumer perception influence consumers’ willing to pay for organic food products. The estimated market potential for organic fruit is GH¢32,117,113 (US$26,453,433) per annum and that of organic vegetable is GH¢1,991,224 (US$1,640,083) per annum suggesting a huge market potential for organic fruits in Ghana.Willingness to Pay, Price Premium, Organic Products, Consumer Perception, Market Potential, Africa, Crop Production/Industries,

Creative Bible Teaching for Seventh-day Adventist Youth Ages 13-18

Problem Studies regarding how adolescents learn have found that the traditional approach of teaching as information or knowledge to be passed on with an emphasis on the mastery of content is not very effective. In view of this, many Christian educators and youth ministry specialists recommend a shift from the traditional methods of teaching the Bible to creative ways of teaching with a focus on active student participation in the teaching-learning process, and on meaning of Bible truths. Method The method used to complete this project was a review of representative literature dealing with theories and concepts of teaching and learning, adolescent development, and creative approaches to Bible teaching. A basic framework of creative Bible teaching for Seventh-day Adventist youth ages 13-18 and a seminar to be used in training lay youth leaders and teachers were developed. Conclusions This project is expected to provide and equip Seventh-day Adventist lay youth leaders and teachers with a knowledge and understanding of creative Bible teaching principles and concepts which they can use to develop their own creative approaches to Bible teaching

Mapping evapotranspiration variability over a complex oasis-desert ecosystem based on automated calibration of Landsat 7 ETM+ data in SEBAL

Fragmented ecosystems of the desiccated Aral Sea seek answers to the profound local hydrologically- and water-related problems. Particularly, in the Small Aral Sea Basin (SASB), these problems are associated with low precipitation, increased temperature, land use and evapotranspiration (ET) changes. Here, the utility of high-resolution satellite dataset is employed to model the growing season dynamic of near-surface fluxes controlled by the advective effects of desert and oasis ecosystems in the SASB. This study adapted and applied the sensible heat flux calibration mechanism of Surface Energy Balance Algorithm for Land (SEBAL) to 16 clear-sky Landsat 7 ETM+ dataset, following a guided automatic pixels search from surface temperature T-s and Normalized Difference Vegetation Index NDVI (). Results were comprehensively validated with flux components and actual ET (ETa) outputs of Eddy Covariance (EC) and Meteorological Station (KZL) observations located in the desert and oasis, respectively. Compared with the original SEBAL, a noteworthy enhancement of flux estimations was achieved as follows: - desert ecosystem ETa R-2 = 0.94; oasis ecosystem ETa R-2 = 0.98 (P < 0.05). The improvement uncovered the exact land use contributions to ETa variability, with average estimates ranging from 1.24 mm to 6.98 mm . Additionally, instantaneous ET to NDVI (ETins-NDVI) ratio indicated that desert and oasis consumptive water use vary significantly with time of the season. This study indicates the possibility of continuous daily ET monitoring with considerable implications for improving water resources decision support over complex data-scarce drylands

Natural Resources and the Economic Growth of West Africa Economies

In this study, we employed the pooled mean group (PMG) regression to examine the effect of natural resources economic rent (coal rent, gas rent, oil rent, forest rent, minerals rent) and foreign direct investment (FDI) on economic growth in West Africa for the period 1996 to 2017. We found strong evidence of a positive relationship between FDI, total natural resources (TNR), total natural gas (TNG), and economic growth in the long-run. However, the study recorded a negative relationship between mineral resources rent, oil rent and gas rent, and economic growth in the long run. The rent from coal also exhibited neutrality on economic growth. While all the short-run coefficients are not statistically significant, the error correction term (ECT) is significant and a negative value of -0.889, signifying cointegration at a 1% significance level. This also implies that the short-run estimates converge towards the long-run estimates to achieve equilibrium at the speed of 89% per annum. Our findings highlight the significance of FDI and total rent from natural resources in stimulating West African economies' growth in the industrialization drive and general welfare. In contrast, this study also highlights the need for policy direction to redesign and realign ownership in the oil and gas sector from multinational co-operations (MNCs) to the locals and the domestic economy to benefit directly from the prevailing environment

Classroom Factors that Affects the Performance of Integrated Science Students at the Junior High School in the Kumasi Metropolis of Ghana

The purpose of the study was to find out the opinions of public and private Junior High School science teachers on the classroom factors that affect performance of students in integrated science in public and private junior high schools in the Kumasi metropolis. The study used descriptive survey designed. The sampling procedure employed for the study was both random and purposive sampling. While the integrated science teachers were purposively sampled due to their subject they teach, the students were randomly selected. Questionnaire and interview were used for data collection. It was found out that integrated science teachers to be aware that classroom factors such as teacher-student relationship, availability of science resource materials, teaching methods employed by teachers, class size, supervision and physical infrastructure are likely to affect performance of students in integrated science at the J.H.S. level. Again, the findings revealed that the selected public schools within the Kumasi metropolis were well resourced with the following: adequate physical infrastructure, adequate science resource materials, adequate science text books and adequate trained science teachers as against their private school counterparts with inadequate physical infrastructure, inadequate science resource materials, inadequate science text books and few trained science teachers. It was recommended that effective supervision must be performed regularly by heads of schools during integrated science lessons. The heads of the public JHS especially, those in the Kumasi metropolis must be made to regularly ensure that their science teachers teach very well during integrated science lessons.

Strategic competences for pricing quantity surveying consultancy services

Professional quantity surveying (QS) services are critical to successful delivery of construction projects within planned budget, quality, and duration. The supply of QS professional services is largely dependent on the price level of services and the willingness of clients to pay. The pricing of professional QS consultancy services has been confronted with a myriad of pricing challenges due to rapid changes in the business environment; the pervasive influence of information technology; and the complexity of clients’ expectation. It isthereforenecessary for QS consultancy firms to develop strategic competence for the pricing of their services. In addition, numerous studies have not given the pricing the pricing of professional services the requisite attention. The purpose of this paper is to investigate the strategic competence for pricing professional QS services. The study was positioned within the positivist tradition. As a result, the quantitative approach was adopted using a survey questionnaire to collect data from QS consultants. The sample size of the study was 79 professional quantity surveyors chosen by using simple random sampling technique from a population of 372 registered professional QS of the Ghana Institution of Surveyors. Using the χ2 test and factor analysis, the study established a relationship between strategic competences and pricing of QS services. The study found that strategic competences for pricing QS professional service is significantly related to the managerial and professional competence of QS consultants. The strategic competences of QS consultants identified by this study include business management, services cost management; and production capabilities. This study provides an empirical basis for QS consultancy firms to focus on strategic direction of their contractual arrangement with clients. Practically, resource configuration and strategic competences for professional service pricing would create price leadership. The study advances the pricing knowledge within the QS practice by demonstrating the nexus between strategic competences and the pricing of QS professional services which hitherto this study have not been effectively investigated
