The purpose of this paper is to analyze the role of brand-related variables as congruence and brand trust on the traditional model formed by perceived quality, perceived value (PV) and satisfaction, in order to compare predictive models for the variables of PV, satisfaction and future intentions of 683 users of sports services.

The analysis has been carried out using two different methodologies. First, three models have been proposed to be analyzed by hierarchical regression models, in order to subsequently propose a fuzzy-set qualitative comparative analysis (fsQCA) to verify the existence or not of necessary and sufficient conditions.

The results indicate that both the classic service variables and the elements related to the brand significantly predict PV, satisfaction and future intentions, in some cases with greater predictive weight being given to congruence and trust than the classic service variables. In addition, linear models have been shown to improve their predictive capability by including brand-related variables, especially the future intentions model. After the fsQCA, congruence and trust have proved to be sufficient combinations to achieve high levels of PV and future intentions, while this is not the case for satisfaction.

The importance of the aspects related to the brand, either on their own or in combination with the classic service variables, is demonstrated, contributing to the literature on brand image in sports services, which is practically non-existent.

El objetivo es analizar el papel de las variables relacionadas con la marca como la congruencia y la confianza en la marca en el modelo tradicional formado por la calidad percibida, el valor percibido y la satisfacción, con el fin de comparar modelos predictivos para las variables de valor percibido, satisfacción e intenciones futuras de 683 usuarios de servicios deportivos.

El análisis se ha llevado a cabo utilizando dos metodologías diferentes. En primer lugar, se han propuesto 3 modelos para ser analizados mediante modelos de regresión jerárquica, con el fin de proponer posteriormente un análisis comparativo cualitativo de conjuntos difusos para verificar la existencia o no de condiciones necesarias y suficientes.

Los resultados indican que tanto las variables clásicas del servicio como los elementos relacionados con la marca predicen significativamente el valor percibido, la satisfacción y las intenciones futuras, en algunos casos con un mayor peso predictivo de la congruencia y la confianza que las variables clásicas de servicio. Además, se ha demostrado que los modelos lineales mejoran su capacidad predictiva al incluir las variables relacionadas con la marca, especialmente en el modelo de intenciones futuras. Después del análisis cualitativo comparativo, la congruencia y la confianza han demostrado ser combinaciones suficientes para lograr altos niveles de valor percibido e intenciones futuras, mientras que no ha sido así en el caso de la satisfacción.

Queda demostrada la importancia de los aspectos relacionados con la marca, por sí solos o en combinación con las variables clásicas del servicio, contribuyendo a la literatura sobre la imagen de marca en los servicios deportivos, que es prácticamente inexistente.

The purpose of this paper is to understand how the nationality and the sport education system could affect the entrepreneurial intentions (EI) of undergraduate sport science students in two different countries.

A total of 249 undergraduate sport sciences (SS) students from Spain and Lithuania were analysed. The EI questioner questionnaire by Liñán and Chen (2009) was used to compile the data during the 2016-2017 academic year.

There are significant differences between the sport science students of Spain and Lithuania. The Lithuanian students have significantly higher means in the variables of EI, perceived behaviour control and professional attraction. Moreover, the variables that predict EI are different, and certain path coefficients of the variables are also significantly different.

The sample originates from one university in each country; therefore, these results may not be generalisable to the entire population.

The SS degrees in Lithuania and Spain should follow different educational policies with the objective of fostering EI and increasing the number of entrepreneurs.

Creating adequate educational policies to foster entrepreneurship in sports across countries could improve the number of entrepreneurs in the sports sectors; thus, the youth unemployment rate will decrease.

There has been no previous research that analyses the EI of sport science students across contexts through the theory of planned behaviour. Moreover, there are no studies that compare the EI of university students between Spain (Western Europe) and Lithuania (Eastern Europe).

The development of multi-hazard risk assessment frameworks has gained momentum in the recent past. Nevertheless, the common practice with openly available risk data sets, such as the ones derived from the United Nations Office for Disaster Risk Reduction Global Risk Model, has been to assess risk individually for each peril and afterwards aggregate, when possible, the results. Although this approach is sufficient for perils that do not have any interaction between them, for the cases where such interaction exists, and losses can be assumed to occur simultaneously, there may be underestimation of losses. The paper aims to discuss these issues.

This paper summarizes a methodology to integrate simultaneous losses caused by earthquakes and tsunamis, with a peril-agnostic approach that can be expanded to other hazards. The methodology is applied in two relevant locations in Latin America, Acapulco (Mexico) and Callao (Peru), considering in each case building by building exposure databases with portfolios of different characteristics, where the results obtained with the proposed approach are compared against those obtained after the direct aggregation of individual losses.

The fully probabilistic risk assessment framework used herein is the same of the global risk model but applied at a much higher resolution level of the hazard and exposure data sets, showing its scalability characteristics and the opportunities to refine certain inputs to move forward into decision-making activities related to disaster risk management and reduction.

This paper applies for the first time the proposed methodology in a high-resolution multi-hazard risk assessment for earthquake and tsunami in two major coastal cities in Latin America.

The purpose of this paper is to study the corrosion process by examining the deterioration of X80 steel exposed to a real petroleum sample containing condensed hydrocarbon plus oilfield-produced water, which were subjected to stimulated emulsions in flowing media at 50°C.

The impedance and polarization spectra were used to assess the aggressiveness of the petroleum sample and tried to find a washing process using condensed hydrocarbon with deionized water. Mössbauer technique was used to identify the phases in precipitated ions obtained during an oven-drying procedure of the oilfield produced water.

The emulsion, chloride, sulphur compounds, heavy metals and the use of a double hydrodynamic system were the most important factors affecting the corrosion of X80 steel. The corrosion rate of this steel increased when oilfield-produced water was stimulated by a double hydrodynamic system (4.56 mm/year). It was determined to be 7.66 mm/year and 4.01 mm/year when steel was exposed to a stimulated emulsion using the petroleum sample and condensed hydrocarbon with deionized water at 24 h, respectively, suggesting that a significant process of hydrocarbon washing could occur and a more corrosive solution was highlighted. Mössbauer results showed that the ions precipitates included the following phases at Wt.%: magnetite (20.0), greigeite (22.8), siderite (3.2), pyrite (2.9), marcasite (26.7) and mackinawite (24.4).

A stimulated hydrocarbon/water emulsions with a more homogeneous solution containing high concentrations of saline compounds and heavy metals were used to simulate the susceptibility to corrosion on the internal pipeline steels exposed to any type of immiscible liquids such as condensed hydrocarbon, or crude oil, containing water. A practical application of the presented research could provide a novel framework for understanding the internal corrosion in pipelines from the simulation of washed hydrocarbons after the stimulated emulsions that can be found in the field. Because more susceptibility to corrosion for pipeline steels would be expected at the end of the transportation of the fluid. It is possible to investigate the possible corrosion mechanisms by using a dried oilfield-produced water sample interacting with the pipeline steels.
