An Analysis of Colombian Power Market Price Behavior from an Industrial Organization Perspective

We analyze the behavior of spot prices in the Colombian wholesale power market, using a series of models derived from industrial organization theory -- We first create a Cournot-based model that simulates the strategic behavior of the market-leader power generators, which we use to estimate two industrial organization variables, the Index of Residual Demand and the Herfindahl-Hirschman Index (HHI) -- We use these variables to create VAR models that estimate spot prices and power market impulse-response relationships -- The results from these models show that hydroelectric generators can use their water storage capability strategically to affect off-peak prices primarily, while the thermal generators can manage their capacity strategically to affect on-peak prices -- In addition, shocks to the Index of Residual Capacity and to the HHI cause spot price fluctuations, which can be interpreted as the generators´ strategic response to these shocks

Evaluación de la exposición al ruido industrial en los trabajadores de una planta de asfalto, en la provincia del Azuay y propuesta de plan de control

El presente trabajo se realizó en una Planta de Hormigón Asfáltico, donde se realizó el estudio del ruido como factor de riesgo bajo las perspectivas de: Salud Ocupacional, Seguridad e Higiene Industrial. Este enfoque holístico, define la influencia que éste riesgo laboral ejerce sobre la pérdida de agudeza auditiva. Se estableció inicialmente el marco teórico y legal vigente sobre el ruido, posteriormente se describió la metodología de estudio, operatividad de variables, y la muestra a estudiar. Luego se procedió a la caracterización de la población y área estudiada, así como las actividades productivas. Dentro de la Higiene Industrial, se monitoreó la exposición del nivel de presión sonora, se realizó el comparativo con el nivel permisible (TWA 8 horas) establecido en el “Reglamento de Seguridad y Salud de los Trabajadores”, D.E. 2393. En términos de Seguridad Industrial, se analizó el equipo de protección personal EPP utilizado, y las variables determinantes. En el ámbito de Salud Ocupacional, se estudió: características personales de trabajadores, patologías relacionadas con sordera, y un cuestionario de exposición al ruido. Finalmente se determinó la existencia de sobreexposición a ruido laboral en la empresa objeto de estudio, mediante el estudio del estado de salud auditiva de los colaboradores se determinó la gran incidencia de personal sano y finalmente se determinó las medidas de control a implementarse enfatizadas a la realidad descubierta en el presente estudio, las que incluyen cambios en equipos y maquinaria, buenas prácticas de trabajo, planes de adiestramiento y capacitación en todo el personal entre otros.

EVALUATING THE OIL SANDS RECLAMATION PROCESS: ASSESSING POLICY CAPACITY AND STAKEHOLDER ACCESS FOR GOVERNMENT AND NON-GOVERNMENTAL ORGANIZATIONS OPERATING IN ALBERTA’S OIL SANDS

By employing interpretive policy analysis this thesis aims to assess, measure, and explain policy capacity for government and non-government organizations involved in reclaiming Alberta's oil sands. Using this type of analysis to assess policy capacity is a novel approach for understanding reclamation policy; and therefore, this research will provide a unique contribution to the literature surrounding reclamation policy. The oil sands region in northeast Alberta, Canada is an area of interest for a few reasons; primarily because of the vast reserves of bitumen and the environmental cost associated with developing this resource. An increase in global oil demand has established incentive for industry to seek out and develop new reserves. Alberta's oil sands are one of the largest remaining reserves in the world, and there is significant interest in increasing production in this region. Furthermore, tensions in several oil exporting nations in the Middle East remain unresolved, and this has garnered additional support for a supply side solution to North American oil demands. This solution relies upon the development of reserves in both the United States and Canada. These compounding factors have contributed to the increased development in the oil sands of northeastern Alberta. Essentially, a rapid expansion of oil sands operations is ongoing, and is the source of significant disturbance across the region. This disturbance, and the promises of reclamation, is a source of contentious debates amongst stakeholders and continues to be highly visible in the media. If oil sands operations are to retain their social license to operate, it is critical that reclamation efforts be effective. One concern non-governmental organizations (NGOs) expressed criticizes the current monitoring and enforcement of regulatory programs in the oil sands. Alberta's NGOs have suggested the data made available to them originates from industrial sources, and is generally unchecked by government. In an effort to discern the overall status of reclamation in the oil sands this study explores several factors essential to policy capacity: work environment, training, employee attitudes, perceived capacity, policy tools, evidence based work, and networking. Data was collected through key informant interviews with senior policy professionals in government and non-government agencies in Alberta. The following are agencies of interest in this research: Canadian Association of Petroleum Producers (CAPP); Alberta Environment and Sustainable Resource Development (AESRD); Alberta Energy Regulator (AER); Cumulative Environmental Management Association (CEMA); Alberta Environment Monitoring, Evaluation, and Reporting Agency (AEMERA); Wood Buffalo Environmental Association (WBEA). The aim of this research is to explain how and why reclamation policy is conducted in Alberta's oil sands. This will illuminate government capacity, NGO capacity, and the interaction of these two agency typologies. In addition to answering research questions, another goal of this project is to show interpretive analysis of policy capacity can be used to measure and predict policy effectiveness. The oil sands of Alberta will be the focus of this project, however, future projects could focus on any government policy scenario utilizing evidence-based approaches.
