Factors predicting non-adherence to Covid-19 guidelines in Guayaquil: The role of mediating factors
(LACCEI Inc., 2022-07) Gonzalez, Yomar; Bravo, Cesar; Hidalgo, Jose; Coello, Silvia
Because the high infectious rates of Coronavirus in south countries, the compliance with prevention guidelines (WHO and Ecuadorian Emergency Committee (COE) prevention guidelines) is necessary to prevent the spread of the virus. People ignoring instructions likely exacerbating the social, economic, and environmental concerns about the pandemic. According to sociodemographic descriptors in urban and rural areas of Guayaquil, average falls to over 70% for people having only below upper secondary education and over 50% for employed people among 20-34 years old, in the middle of a popular economy weakened context. The risk perception (F2), safety climate (F3) and the perceived understanding (F4) are believed to directly influence the compliance (F1) within this context. The mediating role of perceived understanding and safety on compliance response is also considered. This study aimed to identify factors that make an Ecuadorian population more/less likely to comply infectious COE guidelines. The data was collected after the last COVID-19 lockdown in Guayaquil city via online survey of 927 participants. The SPSS®Amos 27.0 - SEM based on maximum likelihood estimation was implemented to evaluate all the considered hypotheses (χ2 /df=3.6, CFI ≥ 0.91, TLI ≥ 0.90, RMSEA ≤ 0.05). The analysis of this hypothesis suggests that positive change in compliance is possible mediating the effect of risk positively. The study leaded to factors affecting a fully restrictions compliance after the last regulation in Guayaquil City (April-May 2021): the self-awareness of following the rules seems to have a strong relationship with perception of having enough knowledge about the coronavirus to primarily leads the behavioral control. Low confidence about government management during crisis events is another factor that enhance non-preventive behavior. This combination seems to be enough to decide about the convenience of following health precautions, especially during period of relaxation.
Household sustainable behavior evaluation and its relationship with socioeconomic indicators in the city of Guayaquil
(LACCEI, Inc., 2019-07) Hidalgo, Jose; Crespo, Tania; Coello, Silvia; GonzÁlez, Yomar
In order to deal with global warming and climate change through the smart management of natural resources and waste elimination for the conservation of the environment, this study aims to evaluate the behavior of household`s residents towards electricity and water consumption and solid waste generation (HSW). The paper also intends to correlate this behavior with socioeconomic indicators, such as: household size, level of education, income generation, labor force and social status. This study relied on 2593 random stratified questionnaires who live in the city of Guayaquil. The findings revealed that different socioeconomic groups houses demonstrate the same tendency in the sustainable consumption attitudes of electricity of water. Subsequently, the findings also ascertained differences are found in the possession of ecological devices. HSEG possess more these kinds of devices than LSEG. Therefore, government strategies should be set in motion to make households more aware of the level of pollution they produce and the inefficacy of their consumption of resources.
The Determinants of Household Electricity Demand in Marginal Ecuador: “A Case Study at Monte Sinai”
(LACCEI Inc., 2018-09) Hidalgo, José; Coello, Silvia; González, Yomar
Electricity demand has grown in almost 75% in the last ten years, and with the addition of 900 thousand new families from rural and marginal areas to the electricity grid, total electricity demand may increase significantly. The understanding of the specific energy consumption patterns of these sectors could explain the influence on the electricity demand and lead the regional government policy to promote their formal electricity access. However, micro level analysis may show different correlations among determinants than those usually reported in previous macro models. The data was taken from a convenience sample of 190 socio-economic surveys at Monte Sinai in order to obtain a system of electricity demand equations and elasticity using Tobit regression model.
Waste to Energy Potential of Domestic Waste Cooking Oil in Guayaquil: A review.
(LACCEI Inc., 2020-07) Hidalgo, José; Coello, Silvia; Crespo, Tania; Amaya, Jorge; Soto, Manuel; Jervis, Freddy; Moreira, Cesar
This paper examines the opportunity for waste cooking oil as a potential source of energy by means of (i) production of biodiesel, (ii) direct burning and (iii) biodegradation. It offers a profound review of existing literature and it measures possible uses of the waste cooking oil produced in the city of Guayaquil. In addition, important chemical and physical properties are presented after the development of a sampling process for after laboratory testing. Conclusions show that the most suitable technology is biodiesel generation, followed by biodegradation, but direct burning is found to be not a possible solution due to its kinematic viscosity.
