A major challenge facing Welsh speciality Small and Medium‐sized Agri‐food Enterprises (SMAFEs) is how to sustain growth in a global market. This can be enhanced through e‐commerce and the marketing of product through the Internet to an international audience. Recent research carried out by the Welsh Enterprise Institute (WEI) found that there may only be 10 per cent of Welsh SMAFEs using the Internet for this purpose. The challenge, therefore, is how to enable SMAFEs to market effectively their products; to put these small firms not only in contact with local markets but also international markets; to ensure a range of “authentic” food products is available to Welsh communities in other countries and those people with affinity to “all things Welsh”; and to establish channels that facilitate repeat purchase by visitors to Wales. This challenge can be responded to by enabling SMAFEs to gain access to the Internet and to be confidence in its use, to develop “user friendly” Web sites, to link to overseas markets through the Internet, and to establish a long‐term customer base. The WEI has undertaken a two stage survey to measure SMAFE usage of e‐mail and the Internet in Wales. The buying habits of Welsh Affinity Groups (WAGs) on the Internet in the USA, Canada and other countries has also been studied and it is planned to establish network links between the SMAFEs and the WAGs, and communities overseas. This paper describes the survey of SMAFEs in Wales and reports on the analysis of the findings together with recommendations for the establishment of a comprehensive Welsh food portal. This is related to the study of the WAGs in the USA and Canada and a proposal for the development of a virtual “market place” between the SMAFEs and the WAGs is explored. The WEI has joined forces with Web design companies WebAware and MAWR Ltd., to offer high quality consultancy and advice to provide Web site and e‐commerce solutions relevant to SMAFEs to create an anticipated multi‐million pound net gain to Wales and the Welsh Agri‐food sector through world‐wide sales. A Welsh food portal is therefore of immense importance as a marketing entrepreneurship interfacing tool not only to Agri‐food enterprises in Wales but also to customers from across the World. The paper concludes by arguing for the need for appropriate support to be provided for speciality Welsh SMAFEs to make them aware of the importance of the adoption of e‐commerce including the Internet and Web sites.

In a conventional finite element analysis, material properties, dimensions and applied loads are usually defined as deterministic quantities. This simplifying assumption however, is not true in practical applications. Using statistics in engineering problems enables us to consider the effects of the input variables dispersion on the output parameters in an analysis. This provides a powerful tool for better decision making for more reliable design. In this paper, a probabilistic based design is presented which evaluates the sensitivity of a mechanical model to random input variables. To illustrate the effectiveness of this method, a simple bracket is analyzed for stress‐strain behavior using commercially available finite element software. Young’s modulus, applied pressure and dimensions are considered as random variables with Gaussian distribution and their effects on maximum stress and displacement is evaluated. The finite element results are compared with reliability based theoretical results which show very good agreement. This demonstrates the capability of commercially available software to handle probabilistic approach design.

The purpose of this study is to identify the main perspectives and trends in educational data mining (EDM) in the e-learning environment from a managerial perspective.

This paper proposes a systematic literature review to identify the main perspectives and trends in EDM in the e-learning environment from a managerial perspective. The study domain of this review is restricted by the educational concepts of e-learning and management. The search for bibliographic material considered articles published in journals and papers published in conferences from 1994 to 2023, totaling 30 years of research in EDM.

From this review, it was observed that managers have been concerned about the effectiveness of the platform used by students as it contains the entire learning process and all the interactions performed, which enable the generation of information. From the data collected on these platforms, there are improvements and inferences that can be made about the actions of educators and human tutors (or automatic tutoring systems), curricular optimization or changes related to course content, proposal of evaluation criteria and also increase the understanding of different learning styles.

This review was conducted from the perspective of the manager, who is responsible for the direction of an institution of higher education, to assist the administration in creating strategies for the use of data mining to improve the learning process. To the best of the authors’ knowledge, this review is original because other contributions do not focus on the manager.

This paper explores the sociological, economic, and political reasons for the collapse of Venezuela's 40-year “pacted” democracy, the eight-year conflict between the country's new president and the opposition, where this conflict has led Venezuela, and what its prospects are for the near future. It proposes that the collapse of Venezuela's “ancien regime” can best be understood by an examination of the impact the rise and fall of oil prices had on its economy, society, and polity. A 20-year economic decline led to the election of Hugo Chavez, a radical outsider, who refused to play along with the country's old political class. This class, in turn, refused to accept Chavez as the legitimately elected president and launched the country on an eight-year roller-coaster ride of counter-revolution and radicalization, which recently ended with the reelection of Chavez and a massive popular endorsement for the establishment of “21st century socialism” in Venezuela. Exactly what such a project means is still unclear, but it so far involves state support for self-managed workplaces and an anti-capitalist and participatory democratic state in the midst of a still functioning capitalist economy. With the apparent defeat of obstacles that are external to the Bolivarian movement, as the pro-Chavez movement is called, such as the domestic opposition and U.S. intervention, the movement is now forced to confront its internal obstacles, such as clientelism, corruption, and personalism, if it is to succeed in the long run.

The purpose of this study is to determine the perception of graduates from teaching degree programs in Early Childhood and Primary Education carried out in Spain in accordance with the European Higher Education Area, who are currently working in classrooms, on their initial training in the educational treatment of diversity (ETD). In addition, potential differences were examined based on the teaching degree that was studied (Early Childhood or Primary).

This study used a mixed methodology including an ad hoc questionnaire and a semi-structured interview. Participants were 140 working teachers who had previously earned their degree in Early Childhood or Primary Education programs. Data analysis was carried out from an integrative perspective, using a basic descriptive focus and content analysis.

The results reveal that the new teachers considered that their initial training in the area of ETD was not as extensive as it should have been and as required by their daily teaching needs. They felt that they had acquired better education in the theoretical content as compared to the practical component. They mentioned a lack of training to attend to students entering the system at a later stage as well as for those with high intellectual abilities, noting that the initial training in ETD focused excessively on deficits and not enough on potentialities and other student diversities.

This study may be useful as it offers an improved adaptation to the reality of early education in ETD classrooms of future teachers, both for the competent education administrations and universities. It may also serve as a starting point to adjust the permanent training offer for teachers to their specific needs, making up for the deficiencies of their initial training.

The purpose of this paper is to present the application of an efficient genetic algorithm to deal with the problem of computing the trade‐off curves for non‐uniform circular arrays. In order to answer questions related to the performance of the non‐uniform circular phased arrays, two criteria are considered to evaluate the design: the criteria of minimum main beam width and minimum side lobe level (SLL) during scanning.

The design of non‐uniform circular arrays is modeled as a multi‐objective optimization problem. The Non‐dominated Sorting Genetic Algorithm II (NSGA‐II) is employed as the methodology to solve the resulting optimization problem. This algorithm is considered to be one of the best evolutionary optimizer for multi‐objective problems. It is chosen for its ease of implementation and its efficiency for computation of non‐dominated ranks. The method is based on the survival of the fittest paradigm, where each individual in the population represents a feasible solution of the optimization problem being solved. The concept of fitness is adapted to take into account the concept of solution quality in multi‐objective problems. This evolutionary method can be used effectively for computing the trade‐off curves between the SLL and the main beam width.

The NSGA‐II algorithm can effectively compute the trade‐off curve of different non‐uniform circular arrays. The simulation results presented in this paper show design options that maintain a low SLL and main beam width without pattern distortion during beam steering. Moreover, these trade‐off curves provide a more realistic approach to the solution of the design problem.

The design problem is set to determine which are the best design configurations or separations between the antenna elements and the best amplitude excitations when a circular structure is employed. Owing to the complex feasible region and the non‐linear dependence of optimization criteria from the decision variables, simple traditional and more sophisticated mathematical programming approaches will lead us to local optimal solutions in the case we can apply them. To the best of our knowledge, this multi‐objective optimization problem has not dealt with before, when two or more conflicting design criteria are taken into account. Therefore, the solution to this problem constitutes the main contribution of our paper.

The integral approach to risk is currently an important background for the local development processes within the sustaintability framework. Given the greater frequency and intensity of extreme climatic events in the period 2005-2015, whose inventory shows a total of 78 extreme climate events in the four thermal stations, the purpose of this paper is to analyze risk situations and their corresponding management in the tourist destinations (TD) of the Atlantic coast of Buenos Aires, Argentina.

Risk management in TDs has not been addressed in depth in the study area. Because of that, this study is exploratory and descriptive, and it was conducted by quantitative and qualitative methods. The occurrence of extreme weather events was the trigger of this study. Thereafter, the existence of risk situations was analyzed from the combination of natural hazards and material and human damage. The actions taken by the public sector were identified to make a diagnosis of the current management of coastal destinations in the province of Buenos Aires.

The result of this study shows that TDs do not apply integral models of risk management, as only 16% of the total registered events were attended by public management from reactive measures to the event. It is believed possible to replicate this study in other TDs, regardless of its main tourism modality, as the analysis carried out in the coastal destinations of Buenos Aires shows that it is necessary to plan and manage risk to avoid and/or mitigate material, social and economic damages of the resident and tourist population.

The main implication of the study, in practical terms, is associated with the incorporation of specific equipment for the detection of storms and other meteorological phenomena. In addition, it should start, from the management, with a process of awareness of the resident and tourist population about the risk and its consequences.

Knowing the existence of natural hazards is a strategic resource for public management. From the identification of the hazards, exposure and vulnerability of the population, it is possible to begin to take measures to mitigate the risk and conduct awareness campaigns about the risk situations that may arise from the occurrence of meteorological phenomena. in beach areas. In this sense, the development of a culture of risk is very important.

The relationship between the occurrence of extreme weather events and tourism has not been addressed in depth in Argentina. Therefore, this work provides an interdisciplinary vision (from tourism and physical geography) about the hazards that extreme phenomena represent in TDs, the situations of risk that they detaches there and the weakness of public management in coastal destinations of Buenos Aires. This case study shows that the absence of planning and risk management has serious implications for the continuity of the development processes of the destinations.

The purpose of this study was to empirically investigate the role of e-service quality factors in predicting e-satisfaction. The study context was spirituality and well-being over-the-top services. The e-service quality factors consisted of perceived functional completeness, perceived performance, perceived quality of interface and interaction, perceived quality of content and information and perceived quality of customer support. The study goal was to ascertain over-the-top services customers’ behavioral intention toward upgrading to premium subscription and the spread of electronic word of mouth.

This study was based upon the integrated stimulus-organism-response framework where e-service quality represented the stimulus, e-satisfaction the organism, behavioral intention and electronic word of mouth as the response. The study used a moderated-mediation approach with e-satisfaction as the mediator and the price value of a premium subscription as the moderator. To empirically test the model, the authors collected data from 312 spirituality and well-being over-the-top services users in India. Partial least squares-structured equation modeling was used to analyze the collected data.

The findings of the study supported the association between e-service quality factors and e-satisfaction while using spirituality and well-being over-the-top service. The results furthermore indicated that satisfied spirituality and well-being over-the-top customers were willing to upgrade to the premium subscription and spread favorable electronic word of mouth. The moderated-mediation study results revealed that the price value of premium subscriptions moderated the relationship between e-service quality and e-satisfaction but did not moderate the relationship between e-satisfaction and behavioral intention, and e-satisfaction and electronic word of mouth.

This study offered a comprehensive stimulus-organism-response theoretical model by using the five e-service quality measurement factors as “stimuli” for motivating the internal state of spirituality and well-being over-the-top subscribers. This was toward sustained usage in over-the-top services subsequent to the end of the freemium period. Furthermore, in this study, both e-service quality theory and user satisfaction theory were integrated into the stimulus-organism-response model. This helped to better comprehend the impact of e-service quality factors in driving e-satisfaction among spirituality and well-being over-the-top service users.

This study revealed the significance of differentiating premium over-the-top subscriptions based on price value. To ensure a high level of e-satisfaction from a premium subscription, a greater emphasis on the e-service quality dimensions was required. This study provided insights to managers regarding the role of favorable electronic word of mouth in fostering effective customer acquisition.

This was one of the first studies which concurrently integrated perceived value of the premium subscription and e-satisfaction with customers’ behavioral intention and electronic word of mouth through the theoretical lens of stimulus-organism-response.
