Epidemiologic case-control studies of small groups of childhood nervous system tumor patients have suggested that parental employment in occupations with exposure to hydrocarbons is a risk factor for disease. The main focus of this case-control study was to assess the paternal occupation at the time of birth of offspring who later developed childhood intracranial and spinal tumors. All children under 15 years of age dying of such tumors in Texas, during the period 1964-1980, were selected as cases. Disease and demographic data were abstracted from death certificates. The birth certificate for each child of the final group of 499 cases was located and parental occupation information, as well as demographic and obstetric data, were collected. The comparison group consisted of a random sample from all Texas live births with the same birth year, race and sex distribution as the cases.^ The paternal occupations were categorized into broad classifications of those involving hydrocarbon exposure versus those that did not, based on the occupation criteria used in the previous studies. Odds ratios did not indicate any increased risk associated with general paternal hydrocarbon exposure in the workplace. In prior studies, increased risk estimates were detected with narrower groups of occupations involving exposure to hydrocarbon materials. The data from this study were classified according to these groups, and again, no increased risks were indicated except for a statistically insignificant but elevated odds ratio for fathers who were paper and pulp mill workers.^ Odds ratios were calculated for specific occupations and industries previously implicated as risk factors. Significantly associated odds ratios (OR) were detected for electricians (OR = 3.5), especially those working for construction companies (OR = 10.0), for employment in the printing occupations (OR = 4.5), particularly graphic arts workers (OR = 21.9), and in the electronics and electronic machinery industries (OR = 3.5). Analysis of the petroleum refining and chemical industries, which were not found in previous study populations, revealed significantly elevated odds ratios of 3.0 for occupations with probable heavy exposure to chemicals and petroleum compounds and 10.0 for salesmen of chemical products. ^

La construcción es una de las actividades más valiosas para la sociedad debido a la naturaleza de los servicios que ofrece y por el volumen de empleos y movimiento económico que genera. Por ello es un elemento fundamental para el desarrollo sustentable. Es una industria compleja, cada vez más dependiente del conocimiento. Debido a su naturaleza fragmentaria y temporal y la alta rotación de personal presenta grandes retos y complicaciones particulares. Estas dificultades en oportunidades pueden transformarse en problemas por la complejidad, localización geográfica o los requisitos técnicos, financieros e innovaciones de los proyectos. Debido a sus características, las construcciones sufren cambios en las condiciones planificadas. Con frecuencia estos cambios conducen a retrasos en la ejecución de los proyectos, costes superiores a los presupuestados y conflictos entre los clientes y los ejecutores. Esto genera problemas de competitividad que afectan tanto a países desarrollados como países en vías de desarrollo. Los problemas de la construcción tienen perniciosos efectos para la sociedad, que pierde recursos que deberían permitir mejores resultados en términos de calidad de vida y beneficios sociales y económicos. Debido a la importancia del sector y los ingentes recursos que se invierten en cada proyecto se justifican los máximos esfuerzos para lograr los mejores desempeños de esta industria. Éste interés ha orientado el desarrollo de investigaciones, para apoyar el logro de los objetivos de mejoramiento continuo y construcción sustentable. Los estudios desarrollados han permitido demostrar el valor añadido del conocimiento en todos los sectores productivos. Para la construcción, los conocimientos ofrecen indicadores de desempeño, datos y lecciones aprendidas provenientes de aciertos y errores. Estos deben conducir a aprendizajes fundamentales para sustentar su competitividad. Sin embargo, a pesar de los conocimientos disponibles y los avances en las técnicas de control gerencial y de proyectos, es alarmante la recurrencia de los problemas de construcción. Esta problemática se manifiesta con severidad en los proyectos de construcción industrial que se desarrollan para el sector petrolero, petroquímico y energético venezolano. El sector presenta evidentes necesidades para un mejor desempeño competitivo por la alta incidencia de retrasos de los proyectos, que implican pérdidas de gran parte de los recursos humanos, financieros, técnicos y conocimientos invertidos. Esta investigación plantea como objetivos analizar la importancia de la construcción y su sustentabilidad, los principales problemas que afectan el sector, la gestión del conocimiento y algunos modelos disponibles para gestionarlos. Igualmente examina las lecciones aprendidas y la productividad y competitividad, con particular atención a los problemas de competitividad venezolanos. Adicionalmente se evalúan las implicaciones del conocimiento como activo estratégico y se caracterizan las empresas de construcción industrial venezolanas. Para ello se identifican las dimensiones que sustentan la gestión del conocimiento en estas empresas, para finalmente determinar las que resultan más idóneas para el nuevo modelo a ser propuesto. Con estos objetivos se desarrolló el estudio empírico. Para ello fueron invitados a participar representantes de 105 empresas y expertos de construcción distintos, todos con experiencias de construcción al sector industrial venezolano. Se obtuvieron 112 respuestas en representación de 41 organizaciones y expertos diferentes. El trabajo de campo inició en Junio de 2012 y culminó en Noviembre de 2012. Los datos obtenidos fueron analizados con apoyo de técnicas estadísticas descriptivas y multivariables. Los objetivos de la investigación se alcanzaron ya que se logró caracterizar el sector de las construcciones industriales y se propuso un nuevo modelo de gestión del conocimiento adecuado a sus características. El nuevo modelo fue formulado atendiendo a criterios de sencillez, bajos costes y facilidad de adaptación para motivar su utilización en organizaciones de construcción industrial variadas. Con ello se busca que resulte de utilidad aún para las organizaciones más pequeñas, con menores recursos o aquellas que enfrentan entornos constructivos complicados. Por último se presentan algunas sugerencias para motivar la comprensión de los fenómenos estudiados en los grupos de interés de la construcción. Se propone analizar estos problemas desde las etapas iniciales de los estudios de ingeniería, de arquitectura, de construcción, de economía y administración. Igualmente se propone desarrollar acciones conjuntas de parte de los sectores académicos, gubernamentales, industriales y asociaciones para el mejoramiento competitivo y desarrollo sustentable global. La propuesta aporta datos sobre el sector constructivo venezolano en un área que presenta grandes carencias y propone un modelo innovador por su sencillez y orientación hacia el uso diario e intuitivo de los conocimientos como recursos fundamentales para la competitividad. Esta orientación puede tener trascendencia más allá del sector descrito, para apoyar la solución de problemas de otras industrias en entornos globales. ABSTRACT Construction is one of the most valuable activities for society due to the nature of the services offered and the number of jobs and revenues generated. Therefore it is a key element for sustainable development. Construction is a complex industry increasingly dependent on knowledge. Its temporary and fragmentary nature and the high staff turnover present great challenges and particular complications to construction. In some cases these conditions may evolve to serious problems because of the complexity, geographic location or even technical, financial and innovative requirements of each project. Due to their characteristics, constructions frequently undergo changes in planned conditions. Often these changes lead to delays in project completion, costs higher than budgeted and conflicts between clients and performers. This creates problems of competitiveness affecting both developed and developing countries. The construction problems have harmful effects on society, since it loses resources that would otherwise allow better results in terms of quality of life and social and economic benefits. The importance and the enormous resources invested in each project justify the efforts to achieve the best performance of this industry. This interest has guided the development of multiple research efforts to support the achievement of construction performance improvements and sustainable construction. The studies carried out have demonstrated the added value of knowledge in all productive sectors. For construction, knowledge offers performance indicators, data and lessons learned from successes and failures. These should lead to fundamental learning to sustain sector competitiveness. However, despite the available knowledge and advances in techniques and project management control, the recurrence of construction problems is alarming. This problem shows itself severely in industrial construction projects that are developed for the Venezuelan oil, petrochemical and energy sectors. These sectors have evident needs for better competitive performance because of the high incidence of project delays, involving loss of much of the human, financial, technical and knowledge resources invested. This research analyzes the importance of construction and sustainability, the main problems affecting the sector, knowledge and some models available to manage them. It also examines the lessons learned and the productivity and competitiveness, with particular attention to the problems of Venezuelan competitiveness. Additionally, the Venezuelan industrial construction companies are characterized evaluating the implications of knowledge as an strategic asset for construction. Moreover, the research evaluates the dimensions that support knowledge management in these companies, to finally identify those that are the most suitable for the new model to be proposed. With these objectives in mind the empirical study was developed. 105 different companies and experts with Venezuelan industrial construction experiences were invited to participate on the survey. 112 responses were obtained representing 41 different organizations and experts. Fieldwork started in June 2012 and ended in November 2012. The data obtained was analyzed with descriptive and multivariate statistical techniques. The research objectives were achieved since the industrial construction sector was characterized and a new management model was proposed based on the particular characteristics of these companies. The new model was formulated according to the criteria of simplicity, low cost and ease of adaptation. This was performed to motivate the use of the new model in various industrial construction organizations, even in smaller companies, with limited resources or those facing complex construction environments. Finally some suggestions to encourage understanding of the phenomena studied among construction stakeholders were proposed. The importance of studying these problems at an early stage of the engineering, architectural, construction, economic and administration studies is highlighted. Additionally, academic, government, industrial organizations and associations are invited to join efforts to improve the competitive and sustainable global development. The proposal provides data on the Venezuelan construction sector in an area that has large gaps and proposes a model which is innovative for its simplicity and suggests the daily and intuitive use of knowledge resources as a key issue to competitiveness. This orientation may have implications beyond the described sector to support the solution of problems of other industries in a global environment.
