This study analyzes the complex relationship between Corporate Social Responsibility (CSR) and Brand Loyalty (BLy) among consumers of mobile phone services, particularly examining how Brand Image (BIm) and Brand Love (BLv) act as mediating factors in this relationship. Quantitative research with a correlational scope and cross-sectional design was conducted among 296 consumers of mobile phone services. A questionnaire comprising 26 questions was administered, with responses quantified using a five-point Likert scale. The results were processed using Confirmatory Factor Analysis and partial least squares structural equation modeling (PLS-SEM). This study revealed that CSR alone does not have a direct and significant association with BLy; however, it is associated with BIm and BLv. Furthermore, BIm and BLv were also found to be associated with BLy, demonstrating that the link between CSR a...

The extraordinary El Niño Costero of 2017 has affected the Peruvian coast, mainly in the Piura region, with the flooding of the Piura river, impacting rural and urban areas in the middle and lower basin. This paper analyses the situation from the perspective of hydrology. Since 2002, the basin has had an early warning system (EWS) made up of a hydrometeorological network and a forecast model, NAXOS. The EWS predicted flows at the Los Ejidos hydrometric station, located immediately upstream of Piura City. The hydrometeorological network has been gradually losing its operation and NAXOS has been left uncalibrated. Its inaccurate forecasts contributed to poor decision-making in disaster prevention in 2017. With the hydro-meteorological information of that year, three models of deterministic forecast of the flow in Los Ejidos have been adjusted by means of multiple linear regression, with 1...

Purpose This study aims to identify whether green advertising and eco-labels influence the purchasing behaviors of organic products or whether the influence of such behaviors is presented through the mediating effect of the attitude and environmental awareness of millennials. Design/methodology/approach This study used a quantitative, correlational and cross-sectional design. A total of 430 millennials participated in the study. The questionnaire consisted of 20 questions, distributed across five variables. It was applied to people outside shopping centers in the city of Quito and Guayaquil, Ecuador. The results were subjected to statistical tests to determine the internal consistency of the instrument. The convergent and discriminant validity of the research model was verified through confirmatory factor analysis and structural equation modeling. SPSS 20 and AMOS 24 were used for statis...

In a highly competitive market, word-of-mouth (WOM) has become one of the most effective ways to attract new customers, as consumer opinions are seen as reliable and have a direct impact on their consumption habits. Based on this premise, the present study aimed to analyze the factors that influence fast-food restaurant consumers in Chile in their intention to share word-of-mouth information. A quantitative approach was adopted for this analysis, using a cross-sectional and correlational design, which included 739 Chilean fast-food consumers, who were given a 25-item questionnaire. This questionnaire was developed from previous research in the field and validated by a panel of experts in marketing and research. The data analysis was conducted using the statistical software Smart PLS 4, allowing for the evaluation of the model’s convergent and discriminant validity, as well as facilitat...

In today’s society, the consumption of organic products presents both significant benefits and potential barriers, as evidenced by the intrinsic and extrinsic factors shaping consumer behavior among university-aged millennials. This study explores the motivators influencing consumer behavior toward organic product purchases and identifies barriers that may inhibit university-aged millennials from engaging in such consumption practices. Utilizing a qualitative research approach, data were gathered through semi-structured interviews with thirty-eight university students in Ecuador and Peru. The analysis employed Grounded Theory methods. The findings of this research indicate that intrinsic factors, including environmental awareness, eco-consciousness, habitual tendencies, health considerations, and personal values, in conjunction with extrinsic factors, such as familial and social influe...

This study examined the impact of green advertising and eco-labels on the attitudes and environmental awareness of millennials purchasing eco-friendly products in shopping centers across Ecuador. The research utilized a quantitative, correlational, cross-sectional methodology with 430 millennials participating. A 20-item survey was administered face-to-face at shopping centers in Quito and Guayaquil, Ecuador. The validity of the research model was established through Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM), employing SPSS 20 and AMOS 24 for statistical evaluations. Findings reveal that green advertising significantly shapes environmental attitudes (β: 0.245) and awareness (β: 0.110), as well as directly influences the purchasing behavior (β: 0.154) towards green products. While eco-labels do not exert a direct effect on purchasing behavior (β: 0.128)...

Social media has become a tool that exerts a significant influence on consumer behavior. In this sense, this study aims to identify whether digital social influence derived from the informational nature of social media content and online member group support influences the subjective norms and environmental attitudes of organic product consumers. This study was developed using a quantitative, correlational, and cross-sectional design. A total of 371 organic product consumers participated in the study, who were administered a questionnaire consisting of 17 questions measured on a 5-point Likert scale. Statistical analysis was performed using SPSS 24 and Smart PLS, and convergent validity, discriminant validity, and structural equation modeling were applied. The results of the study identified that environmental attitudes continue to be a highly influential factor in organic product purcha...

Loop-mediated isothermal DNA amplification (LAMP) methodology offers an opportunity for point-of-care (POC) molecular detection of asymptomatic malaria infections. However, there is still little evidence on the feasibility of implementing this technique for population screenings in isolated field settings.

Background and Objective: Some countries in Latin America (LA) may have the greatest increase in the incidence of renal cell carcinoma (RCC) in both sexes in the coming decades, according to some projections. Increasing efforts to study prognostic factors related to RCC may shorten the regional discrepancies, particularly in the scenario of scarce literature in LA, in comparison to Europe or North America. The evaluation of RCC prognosis allows a greater capacity to anticipate outcomes, in addition to a better understanding of tumor biology and the orientation of the proposed treatment. Herein, we provide a review of the main prognostic factors described in different stages of the disease, considering the progress of publications on kidney cancer in LA. Methods: The PubMed database was used to identify studies on this theme, particularly those from LA. Studies by the Latin American Renal...

The use of L protein coupled magnetic particles for the concentration and purification of immunoglobulin M (mIgM) monoclonal antibodies against Taenia solium was evaluated. Three concentration methods and different elution times were evaluated and the ratio of particles to the ratio of mIgM was optimized. It is demonstrated that: 1) with the use of magnetic particles, a previous concentration of mIgM is not required, which reduces the manipulation of the antibodies and improves the recovery, 2) the use of a binding buffer can be omitted, since the pH of most cell culture supernatants are neutral, and 3) longer elution times (~ 45 minutes) are needed to increase recovery to a level greater than 80%. The study demonstrates that the use of L protein-coupled magnetic particles is a simple and efficient tool for mIgM concentration and purification. © 2020, Instituto Nacional de Salud. All ri...
