Abstract
Purpose
When coatings are applied to industrial equipment, they have to be able to stand the heat produced by solar energy and/or by different conditions on the process. Therefore, the purpose of this paper is to study the effect of temperature on the protective properties of coatings since this parameter degrades the polymer structure. In addition, the temperature effects on dry coating can also be specified.
Design/methodology/approach
In order to know the behaviour of an organic coating at different temperatures, a drying aging cycle was performed by heating on substrate steel and free‐of‐substrate films during ten uninterrupted days at three and different temperatures: 65, 85 and 100°C. At the end of this period, the aged films were analyzed by means of electrochemical impedance spectroscopy (EIS) measurements, thermal analysis (DSC and TGA), Fourier transform infrared spectroscopy (FTIR), and scanning electronic microscopy (SEM).
Findings
The most critical temperature for the aging was 85°C and “over‐cured” phenomenon were observed on the aged films which were reported by EIS, thermal and IR analyses.
Practical Implications
These aging conditions were tested on a very strong and rigid resin containing a barrier pigment. Thus, it can also be applied to other plastic coatings, such as vinyl or alkyd ones, by modifying the temperatures according to glass transition temperature (Tg), as well as the ageing time depending on the hardness and resistance of such coatings and, of course, the protective effect of the pigment. In addition, another aggressive electrolyte, such as synthetic sea water, chloride, sulphide media, as well as inhibitors or ecological pigments could be used in order to predict its behaviour in different corrosive media.
Originality/value
The value of this work is on the specific temperatures used for the aging method applied to a rigid resin which revealed the over‐cured phenomena and the behaviour of the pigment; so if it is applied to a more plastic and flexible coating, it may reveal other phenomena and promote other kind of degradation, maybe even more aggressive ones.

Abstract
Mexico is a nation that attracts significant volumes of international tourists annually. The country possesses abundant natural and cultural assets, with significant opportunities for its tourism sector. Its geographical positioning, favourable weather, and the hospitality of its inhabitants enhance these prospects. Simultaneously, this country exhibits a heightened susceptibility to natural calamities and a dearth of public safety measures. The Mexican tourism industry encounters significant challenges within the framework of the VUCA (volatility, uncertainty, complexity, and ambiguity) model. These challenges include the inherent natural risks associated with the country, the escalating impact of global warming, and the proliferation of organised crime. Within this context, the management of tourist destinations in Mexico neglects significant factors highlighted in theoretical models associated with competitiveness and sustainability. These factors include public security, crisis and disaster management, political will, load capacity, and destination’s image. The predicament encountered by Mexican tour operators is formidable, as the socio-political circumstances in Mexico facilitate the expansion of organised crime, leading to its infiltration into various sectors and regions of the country, with significant impacts on tourist operations. This chapter analyses the effects of organised crime on Mexico’s tourism industry, utilising the VUCA framework as a conceptual lens.

Abstract
Purpose
This paper aims to assess negative emotions in Mexican, Puerto Rican and Spanish service settings in the hospital industry. The paper also attempts to validate previous findings in existing theory and previous studies across three national samples and describes the similarities and differences in negative emotions between Mexican, Puerto Rican and Spanish service settings.
Design/methodology/approach
The current study comprised Mexicans, Puerto Ricans and Spaniards who experienced a service failure (i.e. critical incident) in hospital settings within the past year. A descriptive research design was followed, and a self-administered questionnaire was applied to gather the data from respondents.
Findings
The three-dimensional construct of negative emotions commonly identified in existing theory and previous studies of negative emotions turned out to be four in the current multinational study.
Research limitations/implications
The four-dimensional construct of negative emotions thus revealed is relevant and valuable to research. A number of research limitations are provided, all of which provide opportunities for further research in assessing negative emotions in service settings.
Practical implications
Service providers need to manage and deal with the negative emotions in service failures in an appropriate manner. It is necessary that the front-line staff identify and understand the reasons behind service receiver’s negative emotions in service failures, and that they act accordingly to reduce the intensity of critical incidents and the overall negative consequences.
Originality/value
The negative emotions assessed provide a fruitful contribution and do not only complement additional facets to existing theory and previous studies of negative emotions in service settings but also fortify the notion that further research is required to gain an enhanced understanding and additional insights into them across countries and cultures, just as it is crucial to manage the occurrence of negative emotions in critical incidents accurately.

Abstract
Business history has long been recognized as providing an important dimension to international-business (IB) studies. Much of this historical work has focused on mapping historical growth patterns of multinational enterprises (MNEs) but there is also a growing literature on the long-term impact of MNE investment on host economies, and this paper reviews this research. The focus is primarily on developing-country host economies, and more broadly on the global distribution of wealth and poverty. The article suggests three major arguments. First, it is necessary to take a long-time horizon when assessing impact on host economies. Second, it is necessary to incorporate societal and cultural impacts alongside more traditional measures of economic impact. Third, there is weak historical evidence that MNE’s have had a substantial positive impact over the long run on the development of host developing economies. A hypothesis is suggested that, given adequate domestic growth-supporting institutions and human-capital development, developing countries achieve more sustained development from excluding foreign-owned MNEs rather than hosting them.

Abstract
Purpose
The purpose of this paper is to explore three sociocultural themes common to migrant and seasonal farmworkers and to demonstrate the value of incorporating oral history into healthcare practice and quantitative, qualitative, or mixed-methods research programs, as oral history is a culturally sensitive approach to working with vulnerable populations.
Design/methodology/approach
This paper examines 17 oral histories from farmworkers residing in Ottawa County, Michigan, in the late summer of 2014. The theoretical framework section has two aims. First, it explains the significance of “cultural sensitivity” and “deep structure” to the practice of effective healthcare. Second, it introduces oral history as a form of deep structure cultural sensitivity.
Findings
Three themes emerge from the collected oral histories: stress/anxiety of undocumented status, honor/worth of honest work, and the importance of educating migrant children. Undocumented status is found to be the hub of farmworker health inequities while worth of work and education are described as culturally sensitive points of conversation for healthcare workers engaging with this population. Finally, oral history is found to be a useful method for establishing the deep structure of cultural sensitivity.
Originality/value
This paper gives a voice to farmworkers, an inconspicuous population that disproportionately suffers from health inequities. In addition, this paper acts as a case study promoting the use of oral history as a novel, culturally sensitive research method.

Abstract
Purpose
The aim of this paper is to explore whether the use of an active learning methodology implemented through a mobile phone can help future teachers to develop more effective reading promotion activities than those based on traditional learning methodologies.
Design/methodology/approach
A study was conducted based on the comparison of perceptions of two groups of teacher training students. The experimental group was trained in an active methodology to promote reading on mobile phones, whilst the control group was trained in a classical methodology also using the same devices. Variables were observed using a self-administered questionnaire, and the scores obtained were analysed from their descriptive statistics of the comparison of means of Kruskal–Wallis H test.
Findings
The results showed that students perceived significant improvements associated with active learning methodology. The variables with the most remarkable results were those related to better use of the class, participation and satisfaction. However, the ubiquitous variable obtained the fewest differences, maybe because both learning methodologies were applied using mobile devices.
Originality/value
The conclusions of this study clearly suggest that combining active learning methodologies and the use of mobile phones to promote reading could lead to better results than applying traditional learning methodologies. The value of this study paves the way for future research to move forward in the discovery of effective teaching strategies based on active methods and mobile devices.
