The purpose of this paper is to evaluate the electrochemical behaviour of two carbon steels exposed to acidic geothermal solutions and their resistance to hydrogen induced cracking (HIC), in order to determine the effect of hydrogen damage on the failure process of the steels used for line pipe and casings at a geothermal plant.

Samples of two different steels: ASTM A‐53 Grade B (line pipe) and API L‐80 (casing) were immersed for a duration of 96 h in the electrolyte proposed by NACE to evaluate susceptibility to HIC. Samples of the two steels embedded in non‐conducting Bakelite were subjected to potentiodynamic polarisation scans at room temperature using as the electrolyte brines obtained from different wells at the Cerro Prieto geothermal plant. Hardness tests were performed on the samples before and after the HIC tests in order to determine hardness changes induced by hydrogen penetration as field results indicated embrittlement of the steels after four months of service.

The steels, ASTM A‐53 Grade B and API L‐80 did not exhibit crack sensitivity as no cracks are observed in the tests specimens, though they showed an increase in hardness. The steels exhibited high‐corrosion rates in the brine media at room temperature (3.3 mm/yr), which is expected to increase at higher temperatures.

The work revealed that carbon steels used for line pipes and casings at geothermal plants can exhibit high resistance to HIC, however they corrode at high rates and may show embrittlement. It is suggested that due to the high‐operation temperature, the damage induced by hydrogen resulted in hardness increase but was not sufficient to develop cracks.

The Mexican restaurant industry in Southern California has flourished in the past. However, due to currently tough economic times and the overabundance of Mexican restaurants, it has now become much more difficult to run a successful Mexican restaurant. The majority of the Mexican restaurants that will survive are those that are managed for “excellence”. For the purposes of this article (and since sufficient resources were not available to take in‐depth looks at income statements, balance sheets, 10 year histories, etc.), an “excellent” Mexican restaurant is classified as one that has been around for at least 10 years, is expected to remain in business, and there is at least a small chain of these restaurants.

The purpose of this study is to focus on analyzing the role of music subcultures in the communication and promotion of conspicuous consumption practices. The object of study is the “altered movement” as the music style of the drug subculture in Mexico.

A qualitative content analysis of 78 lyrics and music videos of “altered movement” was carried out between August and December 2018.

The analysis of lyrics and music videos leads to the identification of four narratives (from poor to rich, power through violence, lavish lifestyle and power over women) and diverse symbolic markers (luxury brands mainly) that together, display messages aimed at promoting conspicuous consumption practices.

The current research expands the body of literature of music subcultures in the consumer research area by contesting the common conception of this phenomenon as a healthy source of self-identity formation and deepening into its role as a source of conspicuous consumption practices.

This paper aims to present the numerical models and experimental outcomes pertain to the performance of the parabolic dish concentrator system with a modified cavity-type receiver (hemispherical-shaped).

The numerical models were evolved based on two types of boundary conditions; isothermal receiver surface and non-isothermal receiver surface. For validation of the numerical models with experimental results, three statistical terms were used: mean of absolute deviation, R² and root mean square error.

The thermal efficiency of the receiver values obtained using the numerical model with a non-isothermal receiver surface found agreeing well with experimental results. The numerical model with non-isothermal surface boundary condition exhibited more accurate results as compared to that with isothermal surface boundary condition. The receiver heat loss analysis based on the experimental outcomes is also carried out to estimate the contributions of various modes of heat transfer. The losses by radiation, convection and conduction contribute about 27.47%, 70.89% and 1.83%, in the total receiver loss, respectively.

An empirical correlation based on experimental data is also presented to anticipate the effect of studied parameters on the receiver collection efficiency. The anticipations may help to adopt the technology for practical use.

The developed models would help to design and anticipating the performance of the dish concentrator system with a modified cavity receiver that may be used for applications e.g. power generation, water heating, air-conditioning, solar cooking, solar drying, energy storage, etc.

The originality of this manuscript comprising presenting a differential-mathematical analysis/modeling of hemispherical shaped modified cavity receiver with non-uniform surface temperature boundary condition. It can estimate the variation of temperature of heat transfer fluid (water) along with the receiver height, by taking into account the receiver cavity losses by means of radiation and convection modes. The model also considers the radiative heat exchange among the internal ring-surface elements of the cavity.

Financial inclusion in Peru has been addressed through coverage, quality of financial services, movement of transactions, and service points. The purpose of this chapter is to evaluate for the department of Ancash, Peru, the link between financial inclusion and its socioeconomic factors. Socioeconomic variables and financial inclusion of the Ancash department of the National Household Survey are taken as indicators, later contrasted through the logit model, with the financial inclusion variable being the explained variable.

There is evidence of positive and negative relationships between financial inclusion and socioeconomic variables; these are important components for planning financial inclusion. Raising the levels of formal employment, the educational level and considering the area of residence would be a strategy to generate a dynamic of inclusion in the department of Ancash.

This paper aims to investigate the influence of sustainable enterprise resource planning (S-ERPs) systems implementation on sustainability performance.

A 1 × 2 experiment was conducted, involving a sample of 72 professional accountants enrolled in MPA, MBA and DBA programs at two prominent Egyptian universities. Simple linear regression was used to analyze the data.

The results reveal positive relationships between the implementation of S-ERPs and economic, environmental and social sustainability performance.

Considering the research methodology used, which relies on a laboratory experiment design; nevertheless, empirical data derived from a quasi-experiment conducted in a real-world context would offer valuable insights into the existing literature.

For manufacturing sector managers, the results offer value as organizations can benefit from S-ERP adoption in the internal and external integration of sustainability functions. The findings also provide decision-makers in the manufacturing context, particularly in emerging countries, with tangible reasons to consider S-ERP adoption for holistic sustainability benefits including waste management, resource consumption reduction and management of sustainable supply chain complexities. Further, the findings provide valuable insights for ERP vendors on how they can develop their ERP packages to align with software sustainability criteria.

This study is among the few that experimentally investigates the influence of S-ERPs implementation on sustainability performance within the manufacturing sector, especially in an emerging context such as Egypt. This unique contribution provides valuable insights into the complex connection between technology adoption and sustainability outcomes.

Enterprise resource planning (ERP) systems are complex and comprehensive software designed to integrate business processes and functions. Despite the difficulties and risk, the adoption of ERP systems is expanding rapidly. Universities make large investments in information systems and expect positive impacts. However, universities are facing serious challenges in implementing new technology. Therefore, this research aims to evaluate the impact of ERP systems on higher education (HE) from the perspective of stakeholders’ performance.

This research paper conducted a case study of an ERP system in a Saudi university to explore the impact of ERP system on the performance of the system’s stakeholders among the university’s employees.

The system quality factors (flexibility, compatibility, availability of right data, availability of currency, ease of use and timeliness) were found to affect performance positively, as were service quality factors (tangibility, reliability, responsiveness and assurance). This research further found that factors from pre-implementation, implementation and post-implementation phases had a direct effect on stakeholders’ performance.

Future research would be useful during the maturity phase to include all stakeholders in several Saudi universities. In addition, more research can be beneficial to test the applicability of the impact of the ERP system on stakeholders’ performance in other public sector organisations and in the private sector.

The results suggest that organisations in general and HE institutions in particular should focus on the early stages and the implementation phase if they wish to achieve high standards of stakeholder performance.

This research makes a novel contribution by attempting to evaluate the impact of service quality on stakeholder performance in the ERP environment. The contribution uses service quality as a dimension consisting of four factors – reliability, assurance, tangibility and responsiveness. All four factors were found to be significant on ERP stakeholders’ performance.

This study aims to examine the factors shaping the intentions of people to visit a hostile outgroup.

An exploratory, qualitative research approach was followed. Specifically, 77 semi-structured interviews with citizens of the divided island of Cyprus were conducted.

This study identifies several categories of visitors and non-visitors, depicted along a continuum, and concludes that there is a multiplicity of factors in the socio-political environment which influence the travel intentions of people.

This study not only imparts insights into the way travel decision-making evolves in politically unstable situations but also serves as a stepping stone towards understanding the conditions under which reconciliation between hostile nations may be encouraged by travel.

The purpose of this paper is to investigate the factors of m-learning approaches which can be used for enterprise resource planning (ERP) system training and to propose a theoretical framework for m-learning of ERP systems.

A literature review of several theories relating to success factors for mobile learning (m-learning) and electronic learning (e-learning) are analysed and a theoretical framework of success factors for m-learning of ERP systems is proposed. Two field studies are undertaken to identify the features of e-learning and m-learning systems which users enjoyed and which related to the factors identified in the theoretical framework. The technology acceptance model (TAM) was used to evaluate the acceptance, usefulness and perceived ease of use (PEOU) of the two systems evaluated in the field study, the openSAP e-learning application and the SAP Learn Now m-learning application.

The results confirmed several of the theoretical elements identified in the framework and the m-learning system was rated positively for PEOU and perceived usefulness (PU). The findings confirmed other studies showing the importance of the quality of course content in e-learning and m-learning projects.

The empirical study was limited to a small number of participants in higher education. However, a deeper understanding of the factors influencing m-learning for ERP systems was obtained.

The study provides a valuable practical contribution because the framework can be used in the improved design of an ERP m-learning approach, which in turn can lead to an improvement in ERP training and education programmes and ultimately ERP project success.

Several studies propose the use of m-learning systems. However, research related to the factors impacting on m-learning projects for ERP system training is limited. The paper presents original work and the results provide a valuable contribution to several theories of m-learning.
