The pandemic has enhanced the global phenomenon of disinformation. This paper aims to study the false news concerning COVID-19, spread through social media in Spain, by using the LatamChequea database for a duration from 01/22/2020, when the first false information has been detected, up to 03/09/2021.

A quantitative analysis has been conducted with regard to the correlation between fake news stories and the pandemic state, the motive to share them, their dissemination in other countries and the effectiveness of fact checking. This study is complemented by a qualitative method: a focus group conducted with representatives of different groups within the society.

Fake news has been primarily disseminated through several social networks at the same time, with two peaks taking place in over a half of the said false stories. The first took place from March to April of 2020 during complete lockdown, and we were informed of prevention measures, the country’s situation and the origin of the virus, whereas the second was related to news revolving around the coming vaccines, which occurred between October and November. The audience tends to neither cross-check the information received nor report fake news to competent authorities, and fact-checking methods fail to stop their spread. Further awareness and digital literacy campaigns are thus required in addition to more involvement from governments and technological platforms.

The main limitation of the research is the fact that it was only possible to conduct a focus group of five individuals who do not belong to generation Z due to the restrictions imposed by the pandemic, although a clear contribution to the analysis of the impact of fake news on social networks during the COVID-19 pandemic in Spain can be seen from the privileged experiences in each of the fields of work that were identified. In this sense, the results of the study are not generalizable to a larger population. On the other hand, and with a view to future research, it would be advisable to carry out a more specific study of how fake news affects generation Z.

This research is original in nature, and the findings of this study are valuable for business practitioners and scholars, brand marketers, social media platform owners, opinion leaders and policymakers.

Art return indices are usually estimated based only on a few means of artistic expression (mainly paintings and drawings). Other forms of expression (e.g. sculptures and installations) are generally ignored, in part because they are three-dimensional and, hence, more difficult to measure. We analyze the price determinants as well as the return and risk of three artistic expressions (paintings, drawings and sculptures) executed by Fernando Botero, the most expensive living Latin American artist, to analyze the degree to which their risk and return attributes differ throughout a 20-year period.

We analyzed all paintings, drawings and sculptures executed by Botero and sold at Sotheby’s and Christie’s between 2000 and 2020 (a total of 707 artworks). The data and the images of each artwork were obtained from the web pages of these two auction houses. A hedonic regression was run to explain the price of each artwork and use explanatory variables that are standard in the literature. Art price indices for paintings, drawings and sculptures were constructed using the year-dummy variables estimated in the regressions. We performed a similar analysis for another artist, Carlos Cruz-Diez, as a robustness to our results.

The performance of Botero’s sculptures through time differs markedly from that of his paintings and drawings. Our results suggest that it is possible that returns estimated in the literature could suffer from a bias, as they have usually ignored the performance of sculptures and other artistic expressions. Botero’s paintings provided a return that was comparable to those of his sculptures (3.36% and 3.20%, respectively), they were two times as high as those of his drawings (1.68%). On the other hand, whereas paintings and drawings had similar annual standard deviations (26% and 25.22%, respectively), sculptures had a much smaller standard deviation (16.96%).

A limitation of the hedonic regression method lies in the need to have a significant and diverse sample to identify the true effect of each variable on the price of a good. Another limitation is that we were only able to use art prices from auctions, as this is the only comprehensive source of art price data that is publicly available. These two limitations are shared by all the studies that use the hedonic pricing model.

Our results have practical applications for art collectors and investors, as well as for artists, galleries and, in general, for the whole art market ecosystem. The risk and return attributes of the various artistic expressions of an artist can be different, and thus it makes sense to analyze each one of them individually, as well as their correlations with the other artistic expressions and with traditional and other alternative investments.

The art market is part of what is known as the “orange economy” (also known as the Creative Economy). According to the World Bank, the economic value of the creative sector is not well known or appreciated, even though cultural, creative and artistic activities are vital for our sense of well-being.

To the best of our knowledge, this is the first paper that compares the financial performance of paintings, drawings and sculptures for the case of a specific artist. We chose Botero for three reasons. First, he is a Latin American living artist who has achieved the highest levels of international sales. Second, Botero has worked extensively on various artistic expressions (oil paintings, drawings on different materials and sculptures) throughout his life, a characteristic that is essential to be able to carry out our study. Third, there is a long record of auction sales for each of Botero’s artistic expressions.

Los índices de rentabilidad del arte generalmente se estiman basándose únicamente en unos pocos medios de expresión artística (principalmente pinturas y dibujos). Otras formas de expresión artística (por ejemplo, esculturas e instalaciones) generalmente se ignoran, en parte porque son tridimensionales y, por tanto, más difíciles de medir. Analizamos los determinantes del precio, así como el retorno y el riesgo de tres expresiones artísticas (pinturas, dibujos y esculturas) ejecutadas por Fernando Botero, el artista latinoamericano vivo más caro, para analizar en qué medida sus atributos de riesgo y retorno difieren a lo largo del tiempo, en un período de 20 años.

Analizamos todas las pinturas, dibujos y esculturas ejecutadas por Botero y vendidas en Sotheby’s y Christie’s entre 2000 y 2020 (un total de 707 obras de arte). Los datos y las imágenes de cada obra se obtuvieron de las páginas web de estas dos casas de subastas. Se realizó una regresión hedonante para explicar el precio de cada obra de arte y se utilizaron variables explicativas estándar en la literatura. Los índices de precios de arte para pinturas, dibujos y esculturas se construyeron utilizando variables ficticias anuales estimadas en las regresiones. Realizamos un análisis similar para otro artista, Carlos Cruz-Diez, como análisis de robustez de nuestros resultados.

El desempeño de las esculturas de Botero a través del tiempo difiere marcadamente del de sus pinturas y dibujos. Nuestros resultados sugieren que es posible que los retornos estimados en la literatura sufran un sesgo, ya que generalmente han ignorado el desempeño de esculturas y otras expresiones artísticas. Las pinturas de Botero proporcionaron un retorno comparable al de sus esculturas (3.36% y 3.20%, respectivamente), pero fueron dos veces superiores a los de sus dibujos (1.68%). Por otro lado, mientras que las pinturas y los dibujos tuvieron desviaciones estándar anuales similares (26% y 25.22%, respectivamente), las esculturas tuvieron una desviación estándar mucho menor (16.96%).

Una limitación del método de regresión hedónica radica en la necesidad de contar con una muestra significativa y diversa para identificar el verdadero efecto de cada variable sobre el precio de un bien. Otra limitación consiste en que solo pudimos utilizar precios de arte de subastas, ya que esta es la única fuente completa de datos sobre precios de arte que está disponible públicamente. Estas dos limitaciones son compartidas por todos los estudios que utilizan el modelo de precios hedónico.

Nuestros resultados tienen aplicaciones prácticas para coleccionistas e inversores de arte, así como también para artistas, galerías y, en general, para todo el ecosistema del mercado del arte. Los atributos de riesgo y retorno de las diversas expresiones de un artista pueden ser diferentes, por lo que tiene sentido analizar cada una de ellas individualmente, así como sus correlaciones con las otras expresiones artísticas y con las inversiones tradicionales y otras alternativas.

El mercado del arte forma parte de lo que se conoce como “economía naranja” (también conocida como Economía Creativa). Según el Banco Mundial, el valor económico del sector creativo no es bien conocido ni apreciado, a pesar de que las actividades culturales, creativas y artísticas son vitales para nuestra sensación de bienestar.

Hasta donde hemos podido comprobar, este es el primer artículo que compara el desempeño financiero de pinturas, dibujos y esculturas para el caso de un artista específico. Elegimos a Botero por tres razones. En primer lugar, es el artista vivo latinoamericano que ha alcanzado los mayores niveles de ventas internacionales. En segundo lugar, Botero ha trabajado extensamente en diversas expresiones artísticas (óleos, dibujos sobre distintos materiales y esculturas) a lo largo de su vida, característica que resulta fundamental para poder realizar nuestro estudio. En tercer lugar, existe un largo historial de ventas en subasta de cada una de las expresiones artísticas de Botero.

The purpose of this study is to explore and conducts a critical literature review to answer a fundamental question in the industrial district literature: are clusters and industrial (clusters/IDs) driving sustainability innovation? By intersecting different yet related strands of literature, the authors take stock of what the authors know about sustainability innovation in clusters/IDs.

This paper reviews the literature for conceptualizing sustainability innovation in clusters/districts.

Insights point out that the sustainability innovation process (development and diffusion) in clusters/IDs and their firms couples into mainstream cluster/IDs framework; clusters/IDs enable sustainability innovation through usual mechanisms, fostering collective change toward sustainability innovation, vis-à-vis other settings and strengthening firm sustainability innovation and performance. Sustainability innovation in clusters/IDs requires coupling different multi-scalar institutional systems effectively, and the cooperation of local organizations and policymakers for co-designing dedicated policies. Collective actions are important and firm heterogeneity needs to be considered in the clusters/IDs framework.

This study is original because it provides state-of-the-art on sustainability innovation in clusters/districts, enabling the topic to advance in this direction.

In this chapter, the authors describe the developments towards Roma inclusion in Spain through Successful Educational Actions. First, the authors describe the main characteristics of the Spanish Roma Minority with special regard to their cultural and linguistic diversity and deprivated social situation. After a brief overview of the Spanish education system, the authors give a detailed picture of the educational attainment of the Roma minority in Spain. After then the authors present and analyse the most important successful policies and support programmes for Roma education.

The purpose of this paper is to offer a comprehensive perspective on different facets of knowledge management and their effects on the performance of knowledge-intensive entrepreneurial ventures.

The empirical setting involves small and medium-sized enterprises located in the State of São Paulo, Brazil. Primary data for 223 knowledge-intensive entrepreneurship (KIE) firms was obtained through questionnaires applied to ventures which applied to the innovative research in small business program, a small business innovation research-like initiative run by the São Paulo Research Foundation. Econometric results assessed the drivers of competitiveness in terms of firm growth, research and development intensification and technology transfer.

Results highlight the complexity involved in establishing effective knowledge management processes in terms of driving KIE performance. Notwithstanding, some interesting insights on the moderation effects of strategic knowledge management (SKM) systems over technical skills could be identified with particular emphasis for the case of academic spin-offs. Ecosystem drivers present a good explanation power for technology transfer practices but fall short in providing answers for firm-level growth dynamics. It is also noteworthy that public and private investments in KIE firms are similarly associated with positive impacts – contrary to the view that private investors perform better than governmental sources in picking promising small ventures.

The assessment has provided novel evidence for a sample of KIE ventures concerning the appraisal of performance drivers associated with three dimensions of knowledge management, namely, technical knowledge, SKM and ecosystem features. Firms’ outcomes were addressed from a multidimensional perspective, thus providing a comprehensive perspective of the events under scrutiny.

The purpose of this paper is to study the relevance of heritage collections and the convergence of methodologies and standards traditionally linked to Library and Information Science (LIS) in the development of digital humanities (DH) research in Spain.

This paper is based on a systematic review of scientific publications that are representative of DH in Spain and were published between 2013 and 2018. The analysis considered doctoral theses, journal articles and conference papers.

The results highlight the synergies between documentary heritage, LIS and DH. However, it appears that there is a scarcity of scientific literature to support the confluence of LIS and DH and a limited formal connection between heritage institutions and the areas of academia that reuse and enrich these source collections.

The review of representative scholarly DH publications was mainly based on the metadata that describe the content of articles, thesis and conference papers. This work relies on the thematic indexing (descriptors and keywords) of the analysed documents but their level of quality and consistency is very diverse.

The topic of the study has not been explored before and this work could contribute to the international debate on the interrelation and complementarity between LIS and DH. In addition, this paper shows the contribution that standards and documentary methodologies make to projects in which technology is applied to humanities disciplines. The authors propose that there is an urgent need to strengthen the “scientific relationships” between heritage institutions, as well as enhancing links between the academic field of DH and LIS in order to improve teaching and research strategies in conjunction.

The development of models that allows the evaluation and prediction of erosion processes is an important tool for the management and planning of coastal systems. Mangrove forests systems are under threat by the impacts of erosion, which is also intensified by human activity (and aggravated in the scenarios of global warming and climate change). The purpose of this paper is to develop a model of geographic information systems (GIS) that can be used for any estuary area, but it can also be used for mangroves.

This paper uses georeferentiation which is defined as a set of parameters that best characterize the mangrove areas: elevation (m); geomorphology; geology; land cover; anthropogenic activities; distance to the coastline (m) and maximum tidal range (m). Three different methods are used to combine the various vulnerability parameters, namely, DRASTIC index, analytical hierarchy process (AHP) and square root of the geometric mean.

The three approaches presented in this work show different types evaluating vulnerability to erosion, highlighting a stronger overvaluation of the areas presented with a high vulnerability, through the use of DRASTIC index when compared with two other approaches. The use of the AHP shows similarity to the square root of the geometric mean model, but the AHP also presents a higher percentage of vulnerable areas classified as having medium to very high vulnerability. On the other hand, the use of square root of the geometric mean led to a higher percentage of areas classified as having low and very low vulnerability.

These three qualitative models, based on a cognitive approach, using the set of parameters defined in this research, are a good tool for the spatial distribution of erosion in different mangroves in the world.

Global warming and climate change scenarios require adaptation and mitigation options supported by science-based strategies and solutions.

Previous research has explored the link between sustainability disclosure and reputation but produced contradictory results. This study aims to clarify the sustainability disclosure–reputation relationship through a quantitative analysis of the correlations between these variables reported in empirical research papers. The second objective was to determine how various moderators affect the sustainability disclosure–reputation link.

The meta-analysis was based on a systematic review of the literature covering empirical research on the corporate sustainability disclosure and reputation relationship. A total of 92 articles were meta-analyzed to compile their findings on four extrinsic moderators: company size, ownership, stock listing status and activity sector.

The findings confirm that a significant positive correlation exists between corporate sustainability disclosure and reputation. The moderator analysis also revealed that companies’ different characteristics can explain researchers’ divergent results.

The results have considerable practical relevance for organizational management. First, they can motivate managers to improve and disclose their company’s social and environmental impacts to strengthen their reputation, which in turn will help accelerate the achievement of the Sustainable Development Goals. Second, the findings can ensure organizations develop disclosure and reputation management strategies adapted for each firm’s size, ownership, stock listing status and activity sector.

The results have considerable practical relevance for organizational management.

Second, the findings can ensure organizations develop disclosure and reputation management strategies adapted for each firm’s size, ownership, stock listing status and activity sector.

To the best of the authors’ knowledge, this meta-analysis is the first to clarify the link between disclosure and reputation, which makes a unique contribution to the field of social and environmental accounting. A larger sample of primary research was collected, and key extrinsic moderators were examined to explain prior studies’ contradictory findings.

The purpose of this paper is to use the resource‐based view (RBV) to analyze the influence of the resources available for the export activity (deriving from the firm's size, experience and structure) and the international marketing strategy on export performance.

A sample of Spanish companies is analyzed using logit modeling.

The results show that the resources available are essential antecedents of the type of export strategy chosen by the firm to compete in international markets and of its export performance. Likewise, although the international expansion strategy adopted does not affect export performance, the decision about whether to standardize or adapt the marketing‐mix elements does have an impact.

The paper tries to solve the problem arising from the contradictory results on the effect of export performance antecedents using the RBV as theoretical foundation. With that purpose, the authors analyze jointly the factors proposed as potential determinants in this research.

The purpose of this paper is to present the progress and trends of the literature on art as an investment and to outline potential research lines to be developed.

This work gathers, analyses and critically discusses the attributes of investments in art in general, and in Latin American art in particular.

Most studies report that art (art in general, and Latin American in particular) has offered relatively low but positive real returns, which have tended to be below those offered by stocks and similar to those realized by bonds. Art has a low correlation with other investments.

The literature on the attributes of Latin American art as an investment is limited and new research would help to close the knowledge gap with respect to this segment of the art market as it continues to grow.

Similarly to the research carried out into other segments of the art market, studies on Latin American art suggest that the works of art are worth more, ceteris paribus: the more renowned the artist, the larger the work, whether they were executed in oil, and if they were auctioned at Sotheby’s or Christie’s. The paper also details a series of practical implications for those who participate in the art market.

To the best of the authors’ knowledge, this is the first exhaustive review of the literature on the attributes of Latin American art as an investment. The findings of this study are useful for academics, art collectors, auction houses, gallerists and others who take part in the arts market.

Presentar los avances y las tendencias de la literatura sobre el arte como inversión, y delinear líneas de investigación a ser desarrolladas.

Este trabajo reúne, analiza y discute críticamente los atributos de inversión del arte, en general, y latinoamericano, en particular.

La mayoría de los estudios reportan que el arte (tanto el arte, en general, como el arte latinoamericano, en particular) ha ofrecido rendimientos reales positivos, aunque relativamente bajos, los cuales tienden a ser inferiores de los de las acciones y a ser similares a los de los bonos. El arte tiene una baja correlación con otras inversiones.

La literatura sobre los atributos del arte latinoamericano como inversión es limitada. Es de esperar que nuevas investigaciones permitan ir cerrando la brecha del conocimiento con respecto a esta parte del mercado del arte a la par que éste continúe creciendo.

Los estudios de arte latinoamericano sugieren, similar a las investigaciones sobre otros segmentos del mercado del arte, que las obras de arte valen más, ceteris paribus: cuando el artista es más reputado, a medida que el área de las obras es mayor, si han sido ejecutadas en óleo, y cuando son subastadas en las casas de subastas Sotheby’s o Christie’s. En el trabajo se detallan, además, una serie de implicaciones prácticas para los participantes del mercado de arte.

Hasta donde se ha podido comprobar, esta es la primera revisión exhaustiva acerca de los atributos del arte latinoamericano como inversión. Los resultados de esta investigación son de utilidad para: académicos, coleccionistas de arte, casas de subastas, galeristas, y demás participantes en el mercado del arte.
