RESUMO

The aim of this study was to investigate the status and ranking of job motivational factors using Herzberg Two-factor Theory. This is a descriptive-analytical survey, and researcher-made questionnaire was used for data collection with reliability of 0.92 based on Cronbach Alpha. The statistical population included librarians of 7 special libraries of Ahvaz city, Iran, out of which 53 responded to the questionnaire. Data analysis was done using SPSS and descriptive and statistical statistics. The results indicate that according to librarians' viewpoint, from hygiene or extrinsic factors of job motivation, three components of qualified supervisor, proper management of affairs and desirable working condition, and from intrinsic or subjective factors, three components of success, assignment of responsibilities, and sense of achievement are in the first to third ranks, respectively. On the other hand, appreciation and salary components are in the lowest ranks among other factors. Therefore, it can be concluded that the status of hygiene (extrinsic) factors and motivational (intrinsic) factors is satisfactory in the studied population. However, it is required to plan for improving the current condition and compensating weaknesses(AU)


El objetivo principal del presente estudio fue estudiar el estado y la clasificación de los factores de motivación laboral basados en la teoría de los dos factores de Herzberg. El estudio consistió en una encuesta descriptiva-analítica, la cual se utilizó para recopilar datos. Este cuestionario fue realizado por investigadores y su confiabilidad se calculó 0,92 utilizando el coeficiente alfa de Cronbach. La población estadística incluyó bibliotecarios de bibliotecas especializadas de Ahvaz, 53 de los cuales respondieron el cuestionario. Los datos fueron analizados por el software SPSS utilizando estadísticas descriptivas y estadísticas inferenciales. Los resultados mostraron que desde la perspectiva de los bibliotecarios de las bibliotecas especializadas de salud (externos) o de la motivación laboral, tres componentes del supervisor competente, la gestión adecuada de los asuntos y las condiciones de trabajo óptimas, y entre los factores de trabajo internos (subjetivos), la motivación, tres componentes del éxito, la asignación de responsabilidad y el progreso están en buenas condiciones. También, en función de los resultados de la investigación, en términos de clasificación del estado de los factores motivacionales, los componentes de las condiciones de trabajo óptimas, la gestión adecuada de los asuntos y el supervisor competente se clasifican de primero a tercero, respectivamente. Por otro lado, los componentes de apreciación y salario tienen el rango más bajo entre otros factores. En general, según los hallazgos del estudio, se puede concluir que el estado de salud (externo) y los factores de motivación laboral (interno) en la población estudiada fueron prometedores. Sin embargo, se necesita una planificación principal para mejorar la situación actual y eliminar las debilidades existentes(AU)

RESUMO

This study assessed the available status of waste management system in Ahvaz and its impact on the environment, as well as seven other scenarios in order to quantitatively calculate potential environmental impacts by utilizing the life cycle assessment (LCA) method. These scenarios were as follows: scenario 1: landfilling without biogas collection; scenario 2: landfilling with biogas collection; scenario 3: composting and landfilling without biogas collection; scenario 4: recycling and composting; scenario 5: composting and incineration; scenario 6: anaerobic digestion, recycling, and landfilling; scenario 7: anaerobic digestion and incineration. Emissions were calculated by the integrated waste management (IWM) model and classified into five impact categories: resource consumption, global warming, acidification potential, photochemical oxidation, and eco-toxicity. In terms of resource consumption and the depletion of non-renewable resources, the third scenario showed the worst performance due to its lack of any recycling, energy recovery, and conversion to energy. In terms of greenhouse gas emissions and the effect on global warming, scenario 1 and scenario 2 showed that disposing the whole amount of waste resulted in the most amount of greenhouse gases produced. Moreover, 50% gas and energy recovery from landfills, in comparison with the non-recovery method, reduced the index of global warming by 12%. Finally, scenarios which were based on producing energy from waste showed a reasonably positive performance in terms of greenhouse gases emissions and the influence on global warming.
