    An exploratory analysis of perceived risk among construction workers in three spanish-speaking countries
    (American Society of Civil Engineers (ASCE), 2016) Rodríguez-Garzón, I.; Martínez-Fiestas, M.; Delgado-Padial, A.; Lucas-Ruiz, V.
    Construction is one of the most hazardous industries. This study analyzes occupational risk and focuses specifically on the question of perception of risk based on a sample of construction workers from three countries (Spain, Peru, and Nicaragua) that, in spite of sharing the same language (Spanish), have different socioeconomic levels. The model used for this study is based on the psychometric paradigm. The results of the survey using a questionnaire indicate that the sample population can be separated into two different clusters, each characterized either by a high or a low perception of risk. The authors then attempted to establish a link between the level of perceived risk and different socio-demographic variables. The outcome is that only the training variable significantly altered the perception of risk. This finding, as well as various other aspects of risk perception from the different nations, are discussed. The conclusions of this study provide interesting guidelines for risk management for the construction industry, such as, for example, the increase of the number of hours of worker safety and health training or that the nationality the workers does not appear to affect worker risk perception. © 2016 American Society of Civil Engineers.

    Factores conformantes del riesgo percibido en los trabajadores de la construcción [Factors involved in the perceived risk of construction workers]
    (Universidad Nacional de Colombia, 2015) Rodríguez-Garzón, I.; Martínez-Fiestas, M.; Delgado-Padial, A.; Lucas-Ruiz, V.
    This article is an exploratory study of perceived risk in the construction sector. We used a sample of 514 workers in Spain, Peru and Nicaragua. The method used was the psychometric paradigm and, under its assumptions we have studied nine factors or qualitative attributes of risk. The main statistical analysis was carried out using a classification tree. As a result is obtained that four of the nine attributes studied predict significantly the perceived risk of the sample. The attribute on the delay of the consequences has been the most important predictor in the model, followed by the attribute that explores the potential catastrophic risk and the attribute that explores the serious consequences. Finally the attribute related to the personal vulnerability has emerged. The implications of the results are exposed. © The author; licensee Universidad Nacional de Colombia.

    Perception of occupational risk of firefighters in Quito (Ecuador)
    (Springer New York LLC, 2016) Rodríguez-Garzón, I.; Martínez-Fiestas, M.; Delgado-Padial, A.; Lucas-Ruiz, V.
    This study contributes to research on how firefighters manage the question of safety by analyzing their perception of risk. This work therefore serves to promote safety management, safer behavior and a safer work environment. Specifically, this work sheds light on the implications of firefighters’ perception of their occupational risk. The study applies the paradigmatic psychometric model to describe perceived risk. The sample population comprised 205 firefighters from Quito, Ecuador. The results reveal that likelihood of occurrence (β = 0.222), risk controllability (β = 0.156), catastrophe potential (β = 0.168), and delay in consequences (β = 0.332) are the four factors that best illustrate firefighter’s conception of risk perception (R2 = 32%). Furthermore, this study has identified two groups with different perceptions of risk. The findings show that more than 60% of the sampled firefighters consider that their occupation entails a high level of risk (127 subjects). Finally, the finding that a high level of education enhances a higher perception of risk is discussed. This paper also explores the implications of this research on management, academia and society. © 2015, Springer Science+Business Media New York.
