This study aims to examine the similarity of opinions regarding the stakeholder’s perception about the importance of the different aspects considered when measuring the sustainability of a tourism destination (through the assignment of weights to a previously established system of indicators). Besides, the use of stakeholder analysis networks is validated as a means to understand the different perceptions.

A combination of techniques is used. The stakeholders have been identified using a snowball sample. The network analysis examines the relationships. A power measure based on resource dependency theories is proposed. Possible tensions, as results of different perceptions among individual stakeholders in the context of the measurement of sustainability, are examined using a degree of similarity of opinions based on the Euclidean distance.

Although a large number of stakeholders communicate quite frequently to carry out their activities and believe that they greatly share viewpoints regarding sustainability, the social network analysis reveals that there are significant diversities of opinion. The power indicator and the degree of similarity measure proposed are found to be useful tools for studying the similarities of opinions among the stakeholders.

This approach is applied to sustainability governance conditions. Democratic processes are enhanced to measure sustainability. Directions to improve the sustainability of a tourist destination can be provided by achieving a consensus about sustainability policies. The conclusions about the similarities and differences among the perceptions of different stakeholders can be considered in decision-making processes about sustainability.

No previous studies have identified and analyzed the stakeholder network from the perspectives of measurement of sustainability of a tourism destination and the degree of similarity of their opinions.

本研究旨在考察利益相关者对衡量旅游目的地可持续性时考虑的不同方面的重要性的看法的相似性（通过对先前建立的指标体系分配权重）。此外，我们验证了分析利益相关者使用的社交网络情况是了解不同看法的一种手段。

利用对社交网络的分析，本研究发现，虽然大量的利益相关者为了开展他们的活动而进行频繁的交流，并且分享了大量对可持续发展的看法，但仍然还是存在明显的意见分歧。此外，我们发现所提出的权力指标和相似度测量是研究利益相关者之间意见相似性的有用工具。

本文采用了多种技术的结合。通过雪球抽样的方式来确定利益相关者，并利用对社交网络的分析来研究他们之间的关系。我们提出了基于资源依赖理论的权力衡量方法。我们利用基于欧几里得距离的意见相似度，考察在衡量可持续性的过程中，各个利益相关者之间的不同看法是否会造成紧张

种应用于可持续发展治理条件下的方法，通过加强民主进程来衡量可持续发展，并通过对可持续发展政策达成共识，为改善旅游目的地的可持续发展提供方向。我们分析不同利益相关者的看法的异同，之后可以在关于可持续性的决策过程中加以考虑。

目前还没有从衡量旅游目的地的可持续性角度和分析有关利益相关者以及他们意见相似程度的有关研究。

Este estudio tiene como objetivo examinar la similitud de opiniones en relación a la percepción de los grupos de interés acerca de la importancia de los diferentes aspectos considerados a la hora de medir la sostenibilidad de un destino turístico (mediante la asignación de ponderaciones a un sistema de indicadores previamente establecido). Además, se valida el uso del análisis de redes sociales de los actores como herramienta para comprender las diferentes percepciones.

Utilizando el análisis de redes sociales, el estudio concluye que, aunque un gran número de grupos de interés se comunican con bastante frecuencia para llevar a cabo sus actividades y creen que comparten en gran medida sus puntos de vista sobre la sostenibilidad, existen importantes diversidades de opinión. Además, se constata que el indicador de poder y la medida de grado de similitud propuestos son herramientas útiles para estudiar las similitudes de opiniones entre los actores.

En este artículo se utiliza una combinación de técnicas. Los actores se han identificado mediante la técnica de bola de nieve. Un análisis de redes sociales examina las relaciones. Se propone una medida de poder basada en teorías de dependencia de recursos. Se analiza si puede haber diferencias como resultado de las diferentes percepciones entre los grupos de interés individuales en el contexto de la medición de la sostenibilidad, utilizando un grado de similitud de opiniones basado en la distancia euclidiana.

Éste es un enfoque aplicado a las condiciones de gobernanza de la sostenibilidad de un destino turístico, al potenciar los procesos democráticos para medirla y al brindar orientaciones para mejorarla, logrando un consenso sobre sus políticas. Se analiza las similitudes y diferencias entre las percepciones de diferentes grupos de interés, que podrían ser consideradas en los procesos de toma de decisiones sobre la sostenibilidad.

Ningún estudio previo ha identificado y analizado la red de grupos de interés desde las perspectivas de medición de la sostenibilidad de un destino turístico, y el grado de similitud de sus opiniones.

Two transmission line meshes to simulate electromagnetic waves in the Earth's atmosphere are developed, one with the link transmission lines connected in parallel and the other with connections in series.

The equations describing propagation of waves through these parallel or series meshes are equivalent to the Maxwell equations for TE^r or TM^r modes in a spherical cavity with lossy dielectric material between the external conducting surfaces, respectively.

The transmission line meshes are used for a numerical study of the natural electromagnetic noise due to lightning discharges in the Earth‐ionosphere cavity.

The numerical algorithm finds values for Schumann resonances very close to the experimental ones, which allows us to affirm that this methodology is a valid numerical tool for predicting these resonances on other planets or moons as well.

The purpose of this paper is to determine the level of technical efficiency of the main oil countries worldwide during the period 2010–2017.

The use of the network data envelopment analysis model (NDM) is proposed, in which the technical efficiency of each node is calculated. For the development of the model, three main nodes were identified: exploration and production, industrial transformation and commercialization. Finally, NDM for the international oil industry will be structured, and efficiency will be calculated at the global level and at each node.

The analysis of the results of the application of the NDM raised that the most efficient node was exploration and production, whereas the efficient oil countries were the USA, France, the United Arab Emirates and Angola.

The limitation presented in this investigation was the availability of data.

The practical implications of this type of study are that, through the results obtained, proposals can be made in the oil industry to improve each of the nodes or areas in which efficiency was not reached, as well as make better use of the resources available to this industry in each country.

The social implications of this study are the basis for developing energy policies in the oil industry to help improve the quality of life of users.

The value and originality of this study is based on the joint implementation of the NDM methodology.

The purpose of this paper is to compare the perspectives of public relations professionals against those of the general public in Spain with respect to which communications activities and organizational attributes are relevant to the leadership images of organizations, and what are the characteristics of effective leaders.

This study combines data from the European Communication Monitor (ECM) with the results of a representative online survey carried out by the global market research company IPSOS.

Results show that the general public sees TV interviews as well as TV advertising as communication tools with the biggest potential to shape the leadership image of organizations. When it comes to the attributes of effective leaders, communication professionals overestimate the role of an organization’s vision, while the population much more stresses basic attributes like leading by example and admitting mistakes. PR practitioners underestimate customer service and environmental responsibility and tend to favor more abstract attributes like innovation and CSR.

This paper touches only four sections of the ECM 2014/2015. Participant fatigue may have negatively impacted the quality of the data. A large sample of professionals was approached, but a much small number initiated and completed the online survey. The size of the sample of communication professionals makes it difficult to generalize the results. In addition, future research should extend the study to different groups of stakeholders, such as employees, investors, and suppliers.

While organizations face intensive pressure from evaluation by their stakeholders, discrepancies between the expectations of the general public in regard to leadership negatively affects the communicator’s work to position organizations in society, as well as CEOs and top executives as leaders. On this regards, getting closer to what the population expects will help to understand and improve leadership perceptions.

Very little work has been done in Spain regarding to leadership in public relations or public relations professional’s perceptions about leadership. Most research published to date has focused on the leader’s position in the company, participation in management levels, types of responsibilities assumed and their relative influence and leadership style. Even fewer public relations studies have tried to identify the communication activities that are relevant to the leadership image of organizations and compare the perspectives of public relations professionals on leadership against those of the general public. This dearth of knowledge about stakeholder expectations negatively affects the communicator’s work to position organizations and executive leaders in society.

This study aims to examine the current state of the research activities of scholars in the hospitality and tourism field by analyzing the first 20 years of the new millennium.

Longitudinal analyses using 14,229 journal articles as data source were realized by adopting BibExcel, Gephi and VOSviewer network analysis software packages.

This study provides a comprehensive overview of the hospitality and tourism research based on authorship and social network analysis, with patterns of prolific authors compared over four distinct periods.

The hospitality and tourism academic society is clearly illustrated by tracing academic publication activities across 20 years in the new millennium. In addition, this study provides a guide for scholars to search for multidisciplinary collaboration opportunities. Government agencies and non-governmental organisations can also benefit from this study by identifying appropriate review panel members when making decisions about hospitality- and tourism-related proposals.

To the best of authors’ knowledge, this study is the first to use bibliometric analysis in assessing research published in leading hospitality and tourism journals across the four breakout periods in the new millennium.

The purpose of this paper is to explore the factors that influence the success of internal communication in Spanish companies, specifically the importance of the channels used, activities conducted through ISM and the role played by the communication professional.

The model employed argues that to obtain success in internal communication, three factors are considered necessary: first, communication professionals must participate in strategic decisions; second, they have to use together social media channel and classical channel to communicate with employees; and finally they must choose which activities they carry out during the use of social media. These elements are developed in the literature review. To research practices of internal digital communications and level of success of internal communication across types of organizations, a quantitative survey between professionals from Spanish companies was conducted.

The results revealed that the hierarchical level, participation in the strategic decision process and dedication of the communication practitioner, alongside with the use of face-to-face and online communication channels, and the perceived importance of communication activities conducted through social media platforms are the key factors that influence the quality of internal communication. However, no significant relationship between the level of success and the use of social media channels was found.

The current study has several limitations that should be noted and addressed in future research. The main limitation lies in the fact that the dependent variable – success in communication – is entirely based on communication professionals’ perceptions. Replication studies can be conducted to cross-validate the results obtained from this study using business outcome metrics to measure the communication effectiveness. A further limitation is related to the sampling procedure. Obtaining a representative sample of communications professionals in Spanish companies poses a number of limitations due to the impossibility of having accurate data on the total population.

The findings of the current study provide important implications for public relations professionals on what (i.e. the content) and how to (i.e. the channels) communicate within an organization. In general, internal communicators should move from historical roles as information producers and distributors to advisory roles in strategic decision making. Additionally, the implementation and use of ISM should be carefully revaluated. Communication practitioners should examine and address the difficulties involved in choosing the correct channels, devoting the necessary time to their adequate management, analyzing employees’ feedback and improving the engagement.

The study shows that internal communication practices in Spanish companies are changing. The model used in this research can be applied in an individual organization to evaluate what factors improve the communication of its employees and carry out additional research in other countries or types of organizations to identity new challenges.

This work proposes to test the C‐40 deontological code of collective orientation specifically for franchise associations. The literature review revealed a lack of studies about this type of codes.

This code adopts a semi‐normative approach in trying to standardize what form a deontological code of a franchise association should take. The study has been developed from an international perspective, making easier its spread and generalization. Furthermore, a novel methodology in this area has been applied to test the code: “The Experton Theory”.

As a consequence, from the review of ethical and deontological codes from franchise associations of 46 countries, some associations' statutes and the laws about franchising in some countries, 29 topics were identified. Additionally, 11 more have been added to these contents, making 40 items which conform with what should be integrated into whatever franchising deontological code.

The main limitations of this work refer to the proposition and validation of some questions included in the C‐40 code. Specifically, some of them show opinion divergences of the experts' answers over 25 percent.

The proposed code might be used as a background for franchise associations at an international level. It encourages the increase of ethical and business contents in the existing codes and, therefore, the improvement of the relationships among franchisers, franchisees and the rest of the stakeholders.

This study is focused on a scarcely treated topic in the literature: deontological codes in franchising. In addition, it has been developed from an international perspective, making its spread and generalization easier.

The purpose of this chapter is to carry out a theoretical review of the state of the art in relation to Latin American Small and Medium Enterprises' (SMEs) communication practices and Corporate Social Responsibility (CSR) from 2009 to 2016. A range of recently published papers (2009–2016) is retrieved in a literature search of the Web of Science and Google Scholar under keywords such as ‘CSR’, ‘SME’, ‘Communication’, and ‘CSR in Latin America’. This chapter provides information about CSR in SMEs, indicating what can be found on this topic and how the management of CSR communication can help those firms. It also recognizes the lack of any real formation in SMEs to solve their problems in this area. This chapter emphasizes that, in general terms, SMEs are aware of CSR management opportunities but, because of the aforementioned constraints, their current CSR communications practices are absolutely basic and their management is still limited and short-term. Instead of a generalized exhaustive study, this is an approach to develop new studies in the future. It does not contain empirical results but rather practical information for reflections on CSR and communication in Latin American SMEs. A useful source of information for SME managers. CSR communications policies generate no value unless they have been taken into account in the overall design of corporate CSR policy, particularly if there is no clear vision of how new stakeholders may be more valuable strategically than operationally. This chapter fulfils an identified information/resources need and offers indications for future lines of research.

In this chapter, the authors analyze the academic field of comparative education in Spanish speaking Latin America as a contested construction both in epistemological and political dimensions. First, the authors provide a brief historical account of the origin and development of comparative education in the region since the nineteenth century. Next, they focus on the current state of the field by addressing three aspects: (1) the institutional basis, specially the development of comparative education societies; (2) an account of the contributions of international organizations, both in terms of studies that have been recently conducted and of the development of data bases; and (3) an analysis of prevailing topics as well as theoretical and methodological approaches in a sample of articles published during the 2010-2017 period. The authors conclude by summarizing the main aspects of the current situation, and pointing to future epistemological and political challenges for the field in the region.

This study aims to determine whether the communication of Universities in Madrid (Spain) on social networks through their official channels has caused positive results in students’ perceptions of their trust in university institutions during the first semester of the 2020–2021 term and to measure whether the implementation of happiness management strategies in the communication within university governance affected students’ happiness levels, as well as on the recognition of their belonging to the university.

With an exploratory-correlational approach and a quantitative study, this study conducted a statistical-descriptive analysis based on the premise of a general linear regression model with correlations between the variables, using a data collection instrument, whose construct and content validity was previously assessed by experts, which was answered by 564 students of the Degrees in Communication and Marketing from the Complutense University of Madrid, University of La Laguna, and ESERP Business and Law School. The Kaiser-Meyer-Olkin test and Bartlett’s test of sphericity were implemented to analyze the correlation between variables; Cronbach’s alpha coefficient and Pearson and Spearman’s coefficients were also used.

Those students who used social networks to receive news from university institutions about the COVID-19 pandemic deem these channels official, sound and credible. Similarly, the use of official information from university institutions on social networks increases students’ happiness levels.

To the best of the authors’ knowledge, this is one of the first studies aiming to provide scientific evidence of the relationship between happiness management and university governance. This research’s practical implications lead to attributing added value to these types of means for the university governance that seeks students’ happiness.
