This paper investigates factors affecting Vietnam’s stock prices including US stock prices, foreign exchange rates, gold prices and crude oil prices. Using the daily data from 2005 to 2012, the results indicate that Vietnam’s stock prices are influenced by crude oil prices. In addition, Vietnam’s stock prices are also affected significantly by US stock prices, and foreign exchange rates over the period before the 2008 Global Financial Crisis. There is evidence that Vietnam’s stock prices are highly correlated with US stock prices, foreign exchange rates and gold prices for the same period. Furthermore, Vietnam’s stock prices were cointegrated with US stock prices both before and after the crisis, and with foreign exchange rates, gold prices and crude oil prices only during and after the crisis.

This study presents an interdisciplinary approach towards a critical analysis of some impacts of crude-oil exploration in Niger Delta and polemics of viable conϐlict resolution framework. This approach involves analysis of Ahmed Yerima’s creative portrayal in Hard Ground which revolves around the variables activating conϐlicting emotional interests in matters concerning ‘black gold’ in Nigeria, and how these variables resonant in debates and demands for Nigeria’s polity restructuring because of perceived resource mismanagement. More so, our scope includes an analytical attempt at illuminating elaborately our interpretation of the dimensions to the loud and shrewd inclinations subsuming what some see as solution to the lingering conϐlict, and the suppositions explaining why others see the debates and demands on polity restructuring as dark convoluted ploys aimed at hidden agenda. Hence, through select theories of victimhood, this study attempts to elucidate on the variables propelling conϐlicting emotional interestsabout oil exploration in Niger Delta, by looking interpretively hard and deep on the perspectives, views and suppositions deϐining the ideologies and inclinations propelling them. In the end, this study notes that the disenchantments and troubles with Nigeria’s polity framework and structure as it relates to oil exploration in Niger Delta are subsumed in Hard Ground’s creativecontribution as a means of assessing the points to the fault-lines that characterize the subsisting socio-political structure upon which Nigeria stands and wobbles.

This paper presents a method of sorption using peat for elimination of emergency spills of crude oil and petroleum products and the possibility of energy use of oil-saturated peat. The results of assessment of the sorbent capacity of peat are presented, with waste motor oil and diesel fuel chosen as petroleum products. Natural peat has been found to possess sorption properties in relation to petroleum products. The sorbent capacity of peat can be observed from the first minutes of contact with motor oil and diesel fuel, and significantly depends on their viscosity. For the evaluation of thermal properties of peat saturated with petroleum products, experimental studies have been conducted on determination of moisture and ash content of as-fired fuel. It is shown that adsorbed oil increases the moisture and ash content of peat in comparison with the initial sample. Therefore, when intended for energy use, peat saturated with petroleum products is to be subjected to additional drying. Simulation of net calorific value has been performed based on the calorific values of peat and petroleum products with different ratios of petroleum product content in peat and for a saturated peat sample. The obtained results are compared with those of experiments conducted in a calorimetric bomb and recalculated for net calorific value. A satisfactory discrepancy is obtained, which amounts to about 12%. Options have been considered providing for combustion of saturated peat as fuel (burnt per se and combined with a solid fuel) and processing it to produce liquid, gaseous and solid fuels. Peat can be used to solve environmental problems of elimination of emergency spills of crude oil and petroleum products and as an additional resource in solving the problem of finding affordable energy.

The Impact

This paper aims to examine the main determinants of inflation in Vietnam during the period from 2002Q1 to 2013Q2. The cointegration theory and the Vector Error Correction Model (VECM) approach are used to examine the impact of domestic credit, interest rate, budget deficit, and crude oil prices on inflation in both long and short terms. The results show that while there are long-term relations among inflation and the others, such factors as oil prices, domestic credit, and interest rate, in the short run, have no impact on fluctuations of inflation. Particularly, the budget deficit itself actually has a short-run impact, but its level is fundamentally weak. The cause of the current inflation is mainly due to public's expectations of the inflation in the last period. Although the error correction, from the long-run relationship, has affected inflation in the short run, the coefficient is small and insignificant. In other words, it means that the speed of the adjustment is very low or near zero. This also implies that once the relationship among inflation, domestic credit, interest rate, budget deficit, and crude oil prices deviate from the long-term trend, it will take the economy a lot of time to return to the equilibrium state.
