ALBA: A Political Tool for Venezuela’s Foreign Policy

Despite its founding by Hugo Chávez on the heels of the failed Free Trade Area for the Americas (FTAA) negotiations which took place November 2003, the Bolivarian Alliance for the Americas (ALBA, as it is known for its Spanish acronym) has evolved into a political tool that uses “social power” to facilitate Venezuela‟s positioning as the leader of the anti-U.S. agenda in the region. Fostering political favors and goodwill through the financing of social development projects, ALBA has created a political environment whereby countries on the take and their respective leaders seem deterred from taking public opposing viewpoints to Chávez. To that end, it has provided billions in economic aid to several nations in Latin American and the Caribbean, winning their favor and support for its policies. To date, ALBA counts on eight member nations. Besides Venezuela, it includes Antigua and Barbuda, Bolivia, Cuba, Dominica, Ecuador, Nicaragua, and Saint Vincent and the Grenadines. It also has several observer nations, among them, Grenada, Haiti, Paraguay, Uruguay, and a non-Latin American country, Syria. Throughout its recent history Venezuela has used its oil wealth to pursue political capital. Under the Chávez government it is doing so as part of a strategic effort countering the U.S. Following Cuba‟s demise in the region as the anti-American socialist camp leader, Chávez is attempting to step into Cuba‟s shoes, picking up where Cuba left off over a decade ago and has used the ALBA as a mechanism to help promote his foreign policy. Relying on its own resources, not those of the Soviet Union as Cuba once did, Venezuela has already shown its influence in the international arena, challenging U.S. positions at the Organization of American States (OAS), the United Nations, and even in matters having little if nothing to do with the region, such as Iran‟s nuclear proliferation. Taking advantage of Venezuela‟s oil prices bonanza, Chávez has been spreading economic aid throughout the region, funding several development projects. From stepping in to buy Bolivia‟s soy beans when the U.S. ceased doing so, to helping finance and construct an airport in Dominica, Venezuela‟s ALBA has provided assistance to many states in the region. As in the past, Venezuela has invested significantly both in time and money in the Caribbean, providing development assistance and oil at a discount to Haiti, St. Kitts and Nevis, and the Dominican Republic, although the latter two are neither member nor observer states of ALBA. The aid Chávez has been spreading around may be coming at a cost. It seems it has begun to cause cracks within the CARICOM community, where ALBA already counts on six of its 15 members, leading experts and leaders in the region to question traditional alliances to each other and the U.S. Yet, ALBA‟s ability to influence through aid is dependent on the Venezuelan economy. Its success hinges on continued Venezuelan oil sales at stable prices and the ability of Chávez to remain in power.

Fat Absorption in Commercial French Fries Depending on Oil Type and Coating

This study examines the effect of edible coatings, type of oil used, and cooking method on the fat content of commercially available French fries. In contrast to earlier studies that examined laboratory prepared French fries, this study assesses commercially available French fries and cooking oils. This study also measured the fat content in oven baked French fries, comparing the two cooking methods in addition to the comparisons of different coatings’ oil uptake. The findings of this study were that the type of oil used did have a significant impact on the final oil content of the uncoated and seasoned fries. The fries coated in modified food starch and fried in peanut and soy oils had what appeared to be significantly higher oil content than those fried in corn oil or baked, but the difference was not statistically significant. Additionally, fat content in French fries with hydrocollidial coatings that were prepared in corn oil were not significantly different than French fries with the same coating that were baked.

Influence of hydrobiogeochemistry on transport of chromium through manganese -containing sediments: Experimental and modeling approaches

Chromium (Cr) is a metal of particular environmental concern, owing to its toxicity and widespread occurrence in groundwater, soil, and soil solution. A combination of hydrological, geochemical, and microbiological processes governs the subsurface migration of Cr. Little effort has been devoted to examining how these biogeochemical reactions combine with hydrologic processes influence Cr migration. This study has focused on the complex problem of predicting the Cr transport in laboratory column experiments. A 1-D reactive transport model was developed and evaluated against data obtained from laboratory column experiments. ^ A series of dynamic laboratory column experiments were conducted under abiotic and biotic conditions. Cr(III) was injected into columns packed with β-MnO 2-coated sand at different initial concentrations, variable flow rates, and at two different pore water pH (3.0 and 4.0). In biotic anaerobic column experiments Cr(VI) along with lactate was injected into columns packed with quartz sand or β-MnO2-coated sand and bacteria, Shewanella alga Simidu (BrY-MT). A mathematical model was developed which included advection-dispersion equations for the movement of Cr(III), Cr(VI), dissolved oxygen, lactate, and biomass. The model included first-order rate laws governing the adsorption of each Cr species and lactate. The equations for transport and adsorption were coupled with nonlinear equations for rate-limited oxidation-reduction reactions along with dual-monod kinetic equations. Kinetic batch experiments were conducted to determine the reduction of Cr(VI) by BrY-MT in three different substrates. Results of the column experiments with Cr(III)-containing influent solutions demonstrate that β-MnO2 effectively catalyzes the oxidation of Cr(III) to Cr(VI). For a given influent concentration and pore water velocity, oxidation rates are higher, and hence effluent concentrations of Cr(VI) are greater, at pH 4 relative to pH 3. Reduction of Cr(VI) by BrY-MT was rapid (within one hour) in columns packed with quartz sand, whereas Cr(VI) reduction by BrY-MT was delayed (57 hours) in presence of β-MnO 2-coated sand. BrY-MT grown in BHIB (brain heart infusion broth) reduced maximum amount of Cr(VI) to Cr(III) followed by TSB (tryptic soy broth) and M9 (minimum media). The comparisons of data and model results from the column experiments show that the depths associated with Cr(III) oxidation and transport within sediments of shallow aquatic systems can strongly influence trends in surface water quality. The results of this study suggests that carefully performed, laboratory column experiments is a useful tool in determining the biotransformation of redox-sensitive metals even in the presence of strong oxidant, like β-MnO2. ^
