This dissertation addresses the risk of lung cancer associated with occupational exposures in the petroleum refining and petrochemical industries. Earlier epidemiologic studies of this association did not adjust for cigarette smoking or have specific exposure classifications. The Texas EXposure Assessment System (TEXAS) was developed with data from a population-based, case-comparison study conducted in five southeast Texas counties between 1976 and 1980. The Texas Exposure Assessment System uses job and process categories developed by the American Petroleum Institute, as well as time-oriented variables to identify high risk groups.^ An industry-wide, increased risk for lung cancer was associated with jobs having low-level hydrocarbon exposure that also include other occupational inhalation exposures (OR = 2.0--adjusted for smoking and latency effects). The prohibition of cigarette smoking for jobs with high-level hydrocarbon exposure might explain part of the increased risk for jobs with low-level hydrocarbon exposures. Asbestos exposure comprises a large part of the risk associated with jobs having other inhalation exposures besides hydrocarbons. Workers in petroleum refineries were not shown to have an increased, occupational risk for lung cancer. The increased risk for lung cancer among petrochemical workers (OR = 3.1--smoking and latency adjusted) is associated with all jobs that involve other inhalation exposure characteristics (not only low-level hydrocarbon exposures). Findings for contract workers and workers exposed to specific chemicals were inconclusive although some hypotheses for future research were identified.^ The study results demonstrate that the predominant risk for lung cancer is due to cigarette smoking (OR = 9.8). Cigarette smoking accounts for 86.5% of the incident lung cancer cases within the study area. Workers in the petroleum industry smoke significantly less than persons employed in other industries (p << 0.001). Only 2.2% of the incident lung cancer cases may be attributed to petroleum industry jobs; lifestyle factors (e.g., nutrition) may be associated with the balance of the cases. The results from this study also suggest possible high risk time periods (OR = 3.9--smoking and occupation adjusted). Artifacts in time-oriented findings may result because of the latency interval for lung cancer, secular peaks in age-, sex-specific incidence rates, or periods of hazardous exposures in the petroleum industry. ^

After long deliberations, the European Community (EC) has completed the reform of its audiovisual media regulation. The paper examines the main tenets of this reform with particular focus on its implications for the diversity of cultural expressions in the European media landscape. It also takes into account the changed patterns of consumer and business behaviour due to the advances in digital media and their wider spread in society. The paper criticises the somewhat unimaginative approach of the EC to new media and the political (and at times protectionist) considerations behind some of the Directive's provisions.

Digital TV offers of 200 channels and 500 video-on-demand films, podcasting, mobile television, a new web blog being created every two seconds - these are some of the factual elements depicting contemporary audiovisual media in the digital environment. The present article looks into some of these technological advances and sketches their implications for the markets of media content, in particular as newly emerging patterns of consumer and business behaviour are concerned. Ultimately, it puts forward the question of whether the existing audiovisual media regulatory models, which are still predominantly analogue-based, have been rendered obsolete by the transformed (and continually transforming) digital environment.

In the profoundly changing and dynamic world of contemporary audiovisual media, what has remained surprisingly unaffected is regulation. In the European Union, the new Audiovisual Media Services Directive (AVMS), proposed by the European Commission on December 13, 2005, should allegedly rectify this situation. Amending the existing Television without Frontiers Directive, it should offer a fresh approach and meet the challenge of appropriately regulating media in a complex environment. It is meant to achieve a balance between the free circulation of TV broadcast and new audiovisual media and the preservation of values of cultural identity and diversity, while respecting the principles of subsidiarity and proportionality inherent to the Community. The purpose of this paper is to examine whether and how the changes envisaged to the EC audiovisual media regime might influence cultural diversity in Europe. It addresses subsequently the question of whether the new AVMS properly safeguards the balance between competition and the public interest in this regard, or whether cultural diversity remains a mere political banner.

A standard finding in the political economy of trade policy literature is that we should expect export-oriented industries to attract more assistance than import-competing industries. In reality, however, trade policy is heavily biased toward supporting import industries. This paper shows within a standard protection for sale framework, how the costliness of raising revenue via taxation makes trade subsidies less desirable and trade taxes more desirable. The model is then estimated and its predictions tested using U.S. tariff data. An empirical estimate of the costliness of revenue-raising is also obtained.

In this paper we analyze state level data for total manufacturing constructed from the Annual Survey of Industries for the period 1986-2000 using the nonparametric method of Data Envelopment Analysis (DEA). We assess the extent of surplus labor in the manufacturing sector in the individual states in India. The study also investigates whether the same states show the maximum incidence of surplus labor every year in the sample period and if there any evidence that the extent of surplus labor in manufacturing has been reduced or eliminated in the post-reform era. Our study shows the presence of considerable measure of surplus labor in all of the years in a majority of the states. Things have worsened rather than improved after the reform. Also, the regional distribution of surplus labor has remain fairly unchanged with the same states performing inefficiently both before and after the reform.

El año 2009 significó para Argentina un momento de discusiones que provocaron interpelaciones al sistema democrático. Después 26 años de recuperada la democracia, el Estado modificó la dictatorial legislación que regula los servicios de comunicación audiovisuales. Esto implica una ampliación de la democratización del sistema de medios, tanto en las voces presentes, como en los autorizados para su uso y explotación. Esta nueva legislación permite que más y diversos sujetos puedan hacer uso de su derecho a comunicar y obliga a los oligopolios de la comunicación a ceder parte de sus licencias, de ahí las presiones económicas para frenar la nueva norma.

En base al modelo teórico metodológico de la intencionalidad editorial, que sostiene que el periodismo es objetivo (en tanto remite a fuentes), y parcial (toma de posición), analizamos la cobertura realizada por los diarios Los Andes y UNO sobre la Ley de Servicios de Comunicación Audiovisual. La hipótesis fue que los diarios locales construyeron, a través de piezas periodísticas, un sentido común que respondió a sus intereses corporativos en detrimento del derecho humano a la comunicación. El análisis consistió en un observatorio de medios que combinó metodología cuantitativa y cualitativa, desde el 27 de agosto al 11 de octubre de 2009.

La investigación se enmarca en la perspectiva de estudios sobre la producción de cine y video comunitario, que surgen en el contexto de la democratización político-cultural que vivió América Latina en los años ochenta. Esta producción se ha articulado, desde entonces, con importantes cambios tecnológicos en las formas socio-productivas y con nuevas políticas de comunicación La difusión de las TIC y el abaratamiento de los costos de los equipos desde los años 80? posibilitaron el acceso de mayores sectores de la población al manejo, cada vez más amplio, de herramientas audiovisuales. Esos avances cobran un nuevo impulso en la actualidad con políticas como la Ley de Servicios de Comunicación Audiovisual y otras de similares características en países de la región, inspiradas en concepciones más participativas. El objeto de estudio de esta investigación es la producción de cine y video comunitario que desarrollan organizaciones socioculturales en la zona noroeste del Conurbano Bonaerense. Con ese propósito, se realizaron entrevistas a diversas entidades que fomentan la inclusión de jóvenes a través de la participación en producciones audiovisuales de carácter educativo y cultural. En esas entrevistas nos interesó indagar no sólo las características de los proyectos, las modalidades de difusión y las capacidades en términos de sus recursos humanos y tecnológicos, sino también ahondar en las características que poseen las propias organizaciones, su historia y el tipo de vínculo que establecen con la comunidad de referencia y con el Estado
