Lógica en la toma de decisiones de inversión en el sector de extracción de petróleo y gas natural

Este documento se centra en la presentación de información y análisis de la misma a la hora de establecer la manera en que empresas del sector de extracción de gas natural y generación de energía a base de dicho recurso, toman decisiones en cuanto a inversión, centrándose en la lógica que usan a la hora de emprender este proceso. Esto debido a la constante necesidad de establecer procesos que permitan tomar decisiones más acertadas, incluyendo todas las herramientas posibles para tal fin. La lógica es una de estas herramientas, pues permite encadenar factores con el fin de obtener resultados positivos. Por tal razón, se hace importante conocer el uso de esta herramienta, teniendo en cuentas de qué manera y en que contextos es usada. Con el fin de tener una mayor orientación, este estudio estará centrado en un sector específico, el cual es el de la extracción de petróleo y gas natural. Lo anterior entendiendo la necesidad existente de fundamentación teórica que permita establecer de manera clara la forma apropiada de tomar decisiones en un sector tan diverso y complejo como lo es el mencionado. El contexto empresarial actual exige una visión global, no basada en la lógica lineal causal que hoy se tiene como referencia. El sector de extracción de petróleo y gas natural es un ejemplo particular en cuanto a la manera en cuanto se toman decisiones en inversión, puesto que en su mayoría son empresas de capital intensivo, las cuales mantienen un flujo elevado de recursos monetarios.

Utilidad de la relación estratégica comunitaria y el marketing en el sector de extracción de petróleo crudo y gas natural

El presente trabajo pretende investigar y analizar la utilidad de las relaciones estratégicas comunitarias y el marketing en el sector de extracción de petróleo crudo y gas natural. El mercadeo juega un papel importante a la hora de vender cualquier tipo de producto o servicio. Dependiendo de las características de cada sector, las estrategias de mercadeo pueden llegar a ser más o menos útiles y/o efectivas que otras. Por esta razón, esta investigación pretende analizar la utilidad de las estrategias de marketing comunitario y marketing en el sector de extracción de petróleo crudo y gas natural. La forma de llegar a esa respuesta, puede hallarse por medio de tres caminos: el primero de ellos es encontrar y analizar las características del sector, el segundo es identificar cuáles son las estrategias que están utilizando las empresas que operan este campo, y por último, consistiría en analizar la utilidad de integrar el concepto de relación estratégica comunitaria y marketing al sector de extracción de petróleo crudo y gas natural, en cuanto a los beneficios que el marketing comunitario le traería al sector de interés. El sector de petróleo crudo y gas natural es uno de los más importantes en la economía global y sus clientes son numerosos y totalmente heterogéneos. El mercadeo se vuelve muy complejo para esta industria ya que al tener tipos de clientes tan distintos se dificulta alcanzar las expectativas de cada uno de ellos con una misma estrategia y por supuesto la forma de vender un producto es más compleja. Estos factores mencionados anteriormente están generando relaciones entre empresas y clientes totalmente transaccionales de corto plazo, y es ahí donde se cree que la inclusión de mercadeo relacional y estrategias de mercadeo relacional pueden ser de utilidad para el sector, generando desarrollo y beneficios mutuos tanto para clientes como empresas.

Análisis del concepto de desarrollo sostenible en el acuerdo de asociación de la unión europea y Colombia en el sector hortifructífero

El presente estudio de caso tiene como objetivo explicar la incidencia de la adopción del enfoque del concepto de Desarrollo Sostenible en el Acuerdo de asociación entre la Unión Europea y Colombia en el sector hortifructífero colombiano. Se realiza una análisis y se identifica cómo el enfoque adoptado por las partes, no le brinda igual importancia a los tres pilares del desarrollo sostenible, por lo tanto se dificulta su aplicación en el sector hortifructífero. Partiendo del concepto planteado por Jeffrey Sachs, se evidencian las falencias del concepto adoptado en el acuerdo, y se establecen las dificultades de la aplicación del concepto de desarrollo sostenible estipulado en el acuerdo de asociación, dentro del sector hortifructífero atendiendo a las dinámicas del mundo actual. Esta investigación surge a raíz de la creciente importancia que ha tenido el desarrollo sostenible en el ámbito internacional, estableciéndolo como punto fundamental en la agenda internacional. ría

La aplicación del TLC entre Colombia y USA en el departamento de Cundinamarca: encuentros y desencuentros en la negociación y sus resultados en el sector avícola. (2003-2014)

Desde que Estados Unidos y Colombia firmaron el Tratado de Libre Comercio se establecieron una serie de acuerdos respecto a diferentes sectores, como lo es el sector avícola. Con su entrada en vigencia se hizo efectiva la desgravación arancelaria y por ende la liberalización de este sector, lo cual pone a la avicultura colombiana y en especial a la avicultura del departamento de Cundinamarca en riesgo debido a los bajos niveles arancelarios que se tienen, así como el diferencial de precios de venta entre Colombia y Estados Unidos. Por tal razón el presente trabajo de grado tiene como objetivo principal analizar los efectos que se han dado por el incumplimiento de los compromisos arancelarios acordados en la negociación del tratado en el sector avícola de Cundinamarca, así como analizar las asimetrías existentes en el nivel de desarrollo económico y la competitividad sectorial.

Mortality of Migratory Birds from Marine Commercial Fisheries and Offshore Oil and Gas Production in Canada

There is an imminent need for conservation and best-practice management efforts in marine ecosystems where global-scale declines in the biodiversity and biomass of large vertebrate predators are increasing and marine communities are being altered. We examine two marine-based industries that incidentally take migratory birds in Canada: (1) commercial fisheries, through bycatch, and (2) offshore oil and gas exploration, development, and production. We summarize information from the scientific literature and technical reports and also present new information from recently analyzed data to assess the magnitude and scope of mortality. Fisheries bycatch was responsible for the highest levels of incidental take of migratory bird species; estimated combined take in the longline, gillnet, and bottom otter trawl fisheries within the Atlantic, including the Gulf of St. Lawrence, and Pacific regions was 2679 to 45,586 birds per year. For the offshore oil and gas sector, mortality estimates ranged from 188 to 4494 deaths per year due to the discharge of produced waters resulting in oil sheens and collisions with platforms and vessels; however these estimates for the oil and gas sector are based on many untested assumptions. In spite of the uncertainties, we feel levels of mortality from these two industries are unlikely to affect the marine bird community in Canada, but some effects on local populations from bycatch are likely. Further research and monitoring will be required to: (1) better estimate fisheries-related mortality for vulnerable species and populations that may be impacted by local fisheries, (2) determine the effects of oil sheens from produced waters, and attraction to platforms and associated mortality from collisions, sheens, and flaring, so that better estimates of mortality from the offshore oil and gas sector can be obtained, and (3) determine impacts associated with accidental spills, which are not included in our current assessment. With a better understanding of the direct mortality of marine birds from industry, appropriate mitigation and management actions can be implemented. Cooperation from industry for data collection, research to fill knowledge gaps, and implementation of mitigation approaches will all be needed to conserve marine birds in Canada.

Storm prediction research and its application to the oil/gas industry

The accurate prediction of storms is vital to the oil and gas sector for the management of their operations. An overview of research exploring the prediction of storms by ensemble prediction systems is presented and its application to the oil and gas sector is discussed. The analysis method used requires larger amounts of data storage and computer processing time than other more conventional analysis methods. To overcome these difficulties eScience techniques have been utilised. These techniques potentially have applications to the oil and gas sector to help incorporate environmental data into their information systems

Localization of eIF4A-III in the nucleolus and splicing speckles is an indicator of plant stress

The mechanisms of long-term adaptation to low oxygen environment are quite well studied, but little is known about the sensing of oxygen shortage, the signal transduction and the short-term effects of hypoxia in plant cells. We have found that an RNA helicase eIF4A-III, a putative component of the Exon Junction Complex, rapidly changes its pattern of localisation in the plant nucleus under hypoxic conditions. In normal cell growth conditions GFP- eIF4A-III was mainly nucleoplasmic, but in hypoxia stress conditions it moved to the nucleolus and splicing speckles. This transition occurred within 15-20 min in Arabidopsis culture cells and seedling root cells, but took more than 2 h in tobacco BY-2 culture cells. Inhibition of respiration, transcription or phosphorylation in cells and ethanol treatment had similar effects to hypoxia. The most likely consequence is that a certain mRNA population will remain bound to the eIF4A-III and other mRNA processing proteins, rather than being transported from the nucleus to the cytoplasm, and thus its translation will be suspended.

UK commercial property lease structures: Landlord and tenant mismatch

UK commercial property lease structures have come under considerable scrutiny during the past decade since the property crash of the early 1990s. In particular, tenants complained that the system was unfair and that it has blocked business change. Government is committed, through its 2001 election manifesto, to promote flexibility and choice in the commercial property lettings market and a new voluntary Commercial Leases Code of Practice was launched in April 2002. This paper investigates whether occupiers are being offered the leases they require or whether there is a mismatch between occupier requirements and actual leases in the market. It draws together the substantial data now available on the actual terms of leases in the UK and surveys of corporate occupiers' attitude to their occupation requirements. Although the data indicated that UK leases have become shorter and more diverse since 1990, this is still not sufficient to meet the current requirements of many corporate occupiers. It is clear that the inability to manage entry and exit strategies is a major concern to occupiers. Lease length is the primary concern of tenants and a number of respondents comment on the mismatch between lease length in the UK and business planning horizons. The right to break and other problems with alienation clauses also pose serious difficulties for occupiers, thus reinforcing the mismatch. Other issues include repairing and insuring clauses and the type of review clause. There are differences in opinion between types of occupier. In particular, international corporate occupiers are significantly more concerned about the length of lease and the incidence of break clauses than national occupiers and private-sector tenants are significantly more concerned about leasing in general than public-sector occupiers. Proposed solutions by tenants are predictable and include shorter leases, more frequent breaks and relaxation of restrictions concerning alienation and other clauses. A significant number specify that they would pay more for shorter leases and other improved terms. Short leases would make many of the other terms more acceptable and this is why they are the main concern of corporate occupiers. Overall, the evidence suggests that there continues to be a gap between occupiers' lease requirements and those currently offered by the market. There are underlying structural factors that act as an inertial force on landlords and inhibit the changes which occupiers appear to want. Nevertheless, the findings raise future research questions concerning whether UK lease structures are a constraining factor on UK competitiveness.

Ionic calcium and pH as predictors of stability of milk to UHT processing

This paper describes the use of pH and calcium ion electrodes for investigating factors affecting the heat stability of UHT milk with added calcium chloride. Calcium chloride was added to raw milk to manipulate ionic calcium and pH to within the range that may be typically encountered in raw milk of different compositions and microbial quality. Addition of only 5 mM calcium chloride was sufficient to induce considerable changes in pH, ionic calcium and ethanol stability and alter its stability to UHT treatment. There was a strong relationship between pH decrease and increase in ionic calcium when pH was reduced, whether by addition of calcium chloride or by acidification. Calcium chloride addition was found to increase sediment formation in UHT treated milk. However, sediment could be reduced by addition of stabilizers. Those most effective were ones which decreased ionic calcium and increased pH, such as trisodium citrate and disodium hydrogen phosphate. Sediment formation following UHT treatment was only slight for milk samples whose ethanol stability was greater than 80%.

Analysis of Pan-European attitudes to the eradication and control of bovine viral diarrhoea

At present, national-level policies concerning the eradication and control of bovine viral diarrhoea (BVD) differ widely across Europe. Some Scandinavian countries have enacted strong regulatory frameworks to eradicate the disease, whereas other countries have few formal policies. To examine these differences, the attitudes of stakeholders and policy makers in 17 European countries were investigated. A web-based questionnaire was sent to policy makers, government and private sector veterinarians, and representatives of farmers' organisations. On total, 131 individuals responded to the questionnaire and their responses were analysed by applying a method used in sociolinguistics: frame analysis. The results showed that the different attitudes of countries that applied compulsory or voluntary frameworks were associated with different views about the attribution or blame for BVD and the roles ascribed to farmers and other stakeholders in its eradication and control.

Developments in the Doha Round and WTO dispute settlement: some implications for EU agricultural policy

Progress in the Doha Round is assessed against the changes to the common agricultural policy (CAP) brought about by the Fischler reforms of 2003-2004, and that proposed for sugar. An elimination of export subsidies could place EU exports of processed foods at a competitive disadvantage because of high sugar and milk prices. Provided the single payment scheme falls within the green box, the likely new limits on domestic support should not be problematic for the post-Fischler CAP. However, an ambitious market access package could open up EU markets and bring pressure for further reform. If there is no Doha agreement, existing provisions will continue to apply, but without the protection of the Peace Clause; and increased litigation is likely. Further CAP reform is to be expected.

Novel charge transfer supramolecular assemblies with Keggin anions and 2-amino-5-nitropyridine

Several novel compounds with the non-linear optical chromophore 2-amino-5-nitropyridine (2A5NP) and Keggin polyoxoanions (alpha-isomers), having the general formula (2A5NP)(m)H-n[XM12O40]center dot xH(2)O, M = Mo, W, were synthesised. Compounds were obtained with X = P, n = 3, m = 3 and 4 and X = Si, n = m = 4 ( x = 2 - 6). Thus, for each of the anions [PMo12O40](3-) and [PW12O40](3-) two different compounds were obtained, with the same anion and organic counterpart but with a different stoichiometric ratio. These presented different charge transfer properties and thermal stability. All compounds were characterised by spectroscopic and analytical techniques. The single crystal X-ray diffraction structure of (2A5NP)(4)H-3[PMo12O40]center dot 2.5H(2)O center dot 0.5C(2)H(5)OH showed that the water solvent molecules and the organic chromophores are assembled via infinite one-dimensional chains of hydrogen bonds with formation of open channels, which accommodate [ PMo12O40] 3- and ethanol solvent molecules.

Changes in milk composition and processing properties during the spring flush period

The period, known to UK farmers and processors as the "spring flush", when the cows' diet changes from dry feed to spring pasture, has long been established as a time of change in milk properties and processing characteristics. Although it is believed to be a time when problems in processing are most likely to occur (e.g. milk that does not form clots or forms weak gels during cheesemaking), there is little evidence in the literature of detailed changes in milk composition and their impact on product manufacture. In this study, a range of physicochemical properties were analysed in milk collected from five commercial dairy herds before, during and after the spring flush period of 2006. In particular, total and ionic calcium contents of milk were studied in relation to other parameters including rennet clotting, acid gel properties, heat coagulation, alcohol stability, micelle size and zeta potential. Total divalent cations were significantly reduced from 35.4 to 33.4 mmol.L-1 during the study, while ionic calcium was reduced from 1.48 to 1.40 mmol.L-1 over the same period. Many parameters varied significantly between the sample dates. However, there was no evidence to suggest that any of the milk samples would have been unsuitable for processing - e.g. there were no samples that did not form clots with chymosin within a reasonable time or formed especially weak rennet or acid gels. A number of statistically significant correlations were found within the data, including ionic calcium concentration and pH; rennet clotting time (RCT) and micelle diameter; and RCT and ethanol stability. Overall, while there were clear variations in milk composition and properties over this period, there was no evidence to support the view that serious processing problems are likely during the change from dry feed to spring pasture.

Regulation and innovation: Rethinking 'inclusive' housing design

The Lifetime Homes (LTH) concept initiated in 1989 by the Helen Hamlyn Trust, and subsequently promoted by the Joseph Rowntree Foundation, emerged at a point when there was growing awareness of the decline of both private and public sector housing quality, especially in relation to floorspace standards (Karn & Sheridan, 1994). LTH were intended to offset the concerns of first, the house buying public of the appearance and affordability of homes suitable for successive generations, second, the private house building industry of the cost and marketability of incorporating 'inclusive' design features, and third, Registered Social Landlords (RSLs), who had to balance cost constraints with addressing the needs of a growing number of households with older and/or disabled people. Approved Document Part M of the building regulations was extended in 1999, from public buildings to private dwellings, and currently requires that all new housing meet minimal 'visitability' criteria. Indeed, although the signs are that Part M will be incrementally extended to comprise LTH principles, the paper argues that in their existing form they are insufficient to act as a key component of the government's 'new agenda for British housing'. This paper therefore explores how they might usefully be expanded from an approach, largely based on compromise, to one that inspires innovative, flexible and inclusive house forms, which also challenge design conventions.
