Proved reserves for the Emerging Nigerian Gas Market is estimated to be around 186 trillion cubic feet (Tcf). In the short to medium term, only 54% or approximately 100 Tcf will be available for utilisation, the remaining locked up as Gas Cap Gas, only available on the long term (constrained by OPEC production quota and lack of Gas Utilisation Infrastructure). The objective of this study was to estimate the growth potential of Associated Gas (AG) reserves and more importantly determine probabilistic estimates for potential reserves additions from the extensive Non-associated Gas (NAG) accumulations in the Niger Delta.

The Niger Delta potential AG reserves growth (deterministic) was investigated using historical reserves figures and the probabilistic potential reserves additions from NAG were explored using simple triangular distributions. The Society of Petroleum Engineers (SPE) Reserves classification framework was employed to categorize the Proved reserves (1P or P1) as AG Reserves and Reserves additions from NAG as P2 for Probable reserves (2P or P1+P2) generated as a cumulative distribution till 2050.

The results obtained indicated NAG reserves addition to the proved reserves has a 90% confidence limit of reaching between 78.39 and 89.80 Tcf, and a Standard deviation of 3.42 Tcf in 2050. The 2P reserves estimate in 2050 is expected to lie between 267.06 Tcf and 278.49 Tcf within a confidence interval of 90%. Standard deviation from these values was also estimated as 3.42 Tcf. About total reserves of 275 Tcf would lie below the 75th percentile.

The distribution of reserves obtained would significantly improve future gas reserves availability estimates and plausible production profiles for prospective investors planning to participate in gas to power and other gas utilisation projects in the emerging Nigerian gas market.

Saudis live segregated life between male and female in all forms which might affect their decision making and purchase intention. Understanding the difference between male and female regarding their purchase intention and behavior is growing. Accordingly, this paper outlines three main factors that may affect male and female purchase intention (perceived value - packaging- trust). The main focus was on perceived value, packaging, and trust which are important elements in the current study relationships. Data was collected using an online self-administered survey from consumers in the food industry sector. Structural Equation Modeling (SEM) was used to test the hypotheses. Results of this study indicate that perceived value and trust are positively associated with purchase intention, but not product packaging. More than that, the results indicates no significant effect of gender, which means male and female in Saudi perceived food products the same which does not affect their purchase intention. These findings have important implications for managers in the areas of the food industry and branding. Managers should focus on customers' perceived value and gain their trust to enhance purchase intention.

Aims: This study was aimed to examine the behaviour and pattern of fluctuations in market volume and prices of 21 major vegetables consumed in Trinidad and Tobago.

Study Design:  The study used monthly data for a period of 10 years from 2006 to 2015 obtained from the National Agricultural Marketing and Development Corporation (NAMDEVCO) to investigate fluctuations in market volume and prices of the selected vegetables. Growth trend and seasonality were worked out using linear and lag models.

Methodology: The seasonal indices were worked out by using ratio to moving average decomposition method which was followed by the evaluation of seasonality. Besides, the nature of relationship between market volume and prices was analysed using a lag-linear model.

Results: The results revealed that the seasonality was high (38.71 per cent) in the arrival of large melongene and low (11.79 per cent) in medium sweet peppers arrival to the market. However, the seasonality in price was more (53.68 per cent) in christophene arrival, while it was less (11.96 per cent) in green plantains. The results of lagged linear models indicated that past prices and volumes were important factors that determine the current prices and the marketed volumes in many vegetables.

Conclusion: The study found significant importance to trend in market arrivals and price behaviour of vegetable crops both over the years and across the months, also confirming a negative relationship between market arrivals and prices over the years. Thus, indicating imperfection in marketing of vegetables in the wholesale market, as the traders used the previous week price as guide for setting the current price of the vegetable.

This study evaluates service quality in Tabuk Municipality and tries to identify employee constraints of providing better service. The study used SERVPERF presented by Cronin and Taylor [2] to explore client perceptions of the service quality provided by municipal Tabuk. Interviews with Tabuk Municipality employees were then conducted, which focused on issues raised in the questionnaire analysis. Statistical analyses revealed a positive relationship between the tangible dimension and quality of service.  Interviewees indicated that municipal employees require additional training to improve their skills in working with the public. Moreover, employees viewed incentives as an important avenue for improving the quality of services provided.

This study was analysing the cost and returns of coir products in East Godavari District of Andhra Pradesh. The production performance of coir industry have been examined. The primary data collected from 40 sample coir products manufacturing units/ producers and Cobb Douglas model has been employed to analyse the factors that actually contributed to more coir products  production. The study mainly shows that the increasing returns to scale all coir products manufacturing units.   The study also shows that the expected gross revenue of coir products were to increase 1.12, 1.00, 1.11, 1.01 and 1.02 percent for coir fibre, yarn, rope, mattings and mats respectively these units when the variable inputs in the production functions are at once increased by one percent. Further, finally comparative cost and returns medium sized coir units are in            better economic and institutional conditions comparative to small size of coir units in terms of profitability.
