The authors will review the main concepts of graphs, present the implemented algorithm, as well as explain the different techniques applied to the graph, to achieve an efficient execution of the algorithm, both in terms of the use of multiple cores that the authors have available today, and the use of massive data parallelism through the parallelization of the algorithm, bringing the graph closer to the execution through CUDA on GPUs.

In this work, the authors approach the graphs isomorphism problem, approaching this problem from a point of view very little worked during all this time, the application of parallelism and the high-performance computing (HPC) techniques to the detection of isomorphism between graphs.

Results obtained give compelling reasons to ensure that more in-depth studies on the HPC techniques should be applied in these fields, since gains of up to 722x speedup are achieved in the most favorable scenarios, maintaining an average performance speedup of 454x.

The paper is new and original.

The theory of monopoly price was originally formulated by Carl Menger at the inception of the marginalist revolution in 1871 and represented the dominant theoretical approach to monopoly until the 1930s. Despite its impeccable doctrinal pedigree and lengthy dominance, the theory abruptly disappeared from the mainstream neoclassical literature after the Monopolistic Competition Revolution, to be revived and reformulated after World War II by Ludwig von Mises. The present paper describes the theory as it was offered in its most sophisticated pre‐war form by American economist Vernon A. Mund, who published an unjustifiably neglected volume on monopoly theory that appeared in the same year as the classic works by Joan Robinson and Edward Chamberlain. This paper then attempts to draw out the critical implications of Mund’s formulation of the theory for the current neoclassical orthodoxy in monopoly and competition theory, including the elasticity of demand curves facing individual producers under competition, the time perspectives that are most relevant in analyzing the pricing process, the proper role of long‐run equilibrium in this analysis, and the misapplication of the marginal revenue and marginal cost concepts. Finally, the paper suggests a number of reasons why the theory was swept aside in the aftermath of the Chamberlain/Robinson Revolution with almost no resistance from its most prominent exponents.

The purpose of this paper is to examine the role played by the visual arts in expressing and shaping the nation brand. In doing so, it establishes the centrality of visual discourse in nation branding; illustrating that discursive strategies can directly alter the nation brand’s perception.

This single case study drawing on in-depth interviews, field observation and secondary/historical material, applies mediated discourse analysis and critical discourse analysis to capture a transitional period in the cultural policies and nation branding rhetoric across a time frame of 60 years.

This study establishes the visual arts as a significant carrier of meaning, thus reflecting changes in the national discourse. This analysis illustrates that publicly supported visual arts can articulate policy aspirations and provide insight into the power of competing national discourse which co-exists, thereby shaping the internal and external nation brand.

The study focuses on the visual arts and the context of Venezuela. Future research could expand this to look at the visual arts in other national or regional contexts.

The paper establishes visual art as central to expressing national identity and policy, and a tool for examination of national identity and policy. More broadly, the paper establishes public support for the (visual) arts as central to nation-branding projects providing insight for those engaged in such campaigns to prioritize arts funding.

The authors’ study indicates the marketing relevance of visualization of the nation through the arts and establishes the visual arts as a central tenant of the nation brand.

For the most part, the book presents a comparative assessment of Austrian economic theories with the predominant neo-classical economic theories. One fundamental theme is that Austrian economic theories are significantly better than that of neo-classical economics and the author provides a variety of reasons to support that conclusion. The author starts with a direct comparison of these two schools in chapter 1. The comparison of the neo-classical economic principles and methodology with Austrian thinking is done in a commendable manner and the summary table in chapter 1 is excellent.

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.

The purpose of this paper is to correct Rozeff (2010). He contends that fractional-reserve banking is legitimate and efficacious. The authors demonstrate that it is not.

The design of this paper is to quote widely from Rozeff (2010) and then to expose his errors of analysis.

The authors demonstrate that fractional-reserve banking is neither legitimate nor efficacious.

Money is the lifeblood of the economy. If so, then banking is the marrow of the economy, since it is from that sector that money arises in the first place. It is crucially important, then, that the monetary system be based on sound principles. Fractional-reserve banking is a violation of these sound principles. Therefore, it is valuable to demonstrate that this is indeed the case.

This research explores the impostor phenomenon (IP) within the context of gender and leadership, aiming to transform impostor feelings into catalysts for leadership empowerment and positive career outcomes.

Utilizing grounded theory, this study conducts in-depth interviews with 34 female Spanish senior executives to analyze their experiences with IP.

The research reveals that top executive women are not only affected by IP but can also harness it to foster personal and professional growth. It identifies key strategies – such as self-reflection, effective communication and cultivating positive habits – that enable women to transform IP into a lever for enhancing their careers. This approach leads to a proposed virtuous cycle model that empowers women to overcome the negative impacts of IP and advance their leadership capabilities.

This study contributes to the literature on gender and leadership by offering insights into the gendered nuances of IP. By framing IP as a potential catalyst for growth rather than a barrier, the study provides practical tools for human resource (HR) departments to promote gender diversity at senior levels. It also advocates for HR practices to dismantle internal barriers to women’s career progression and address conscious and unconscious gender biases.

Existing research suggests motherhood hinders women’s advancement to top management roles, but its specific influence on women who have achieved senior leadership is unexplored.

This research uses a qualitative approach based on 34 in-depth, semi-structured interviews with Spanish female executives who hold board positions or have the potential to become board members in male-dominated industries.

This study identifies motherhood as a key driver in career growth, countering the view of it as a barrier. Narratives from female leaders revealed that motherhood did not impede their careers, challenging the “motherhood penalty” notion. We introduce the concept of “motherhood enrichment,” highlighting its positive impact on leadership skills and career progression in top executive roles.

These findings can challenge prejudices about the negative impact of motherhood on women’s careers and support policies promoting work–life balance and family-friendly cultures in organizations.

This study suggests the “motherhood-work enrichment” (MWE) concept in leadership, recognizing motherhood as a catalyst for leadership qualities and offering a preliminary theoretical model to explain MWE in the context of concurrent mother-top manager roles.

The purpose of this study is to comprehensively examine the ethical implications surrounding generative artificial intelligence (AI).

Leveraging a novel methodological approach, the study curates a corpus of 364 documents from Scopus spanning 2022 to 2024. Using the term frequency-inverse document frequency (TF-IDF) and structural topic modeling (STM), it quantitatively dissects the thematic essence of the ethical discourse in generative AI across diverse domains, including education, healthcare, businesses and scientific research.

The results reveal a diverse range of ethical concerns across various sectors impacted by generative AI. In academia, the primary focus is on issues of authenticity and intellectual property, highlighting the challenges of AI-generated content in maintaining academic integrity. In the healthcare sector, the emphasis shifts to the ethical implications of AI in medical decision-making and patient privacy, reflecting concerns about the reliability and security of AI-generated medical advice. The study also uncovers significant ethical discussions in educational and financial settings, demonstrating the broad impact of generative AI on societal and professional practices.

This study provides a foundation for crafting targeted ethical guidelines and regulations for generative AI, informed by a systematic analysis using STM. It highlights the need for dynamic governance and continual monitoring of AI’s evolving ethical landscape, offering a model for future research and policymaking in diverse fields.

The study introduces a unique methodological combination of TF-IDF and STM to analyze a large academic corpus, offering new insights into the ethical implications of generative AI across multiple domains.

This study aims to help develop “business principles for stakeholder capitalism” in two steps. First, the study defines internal logic of three theories of capitalism and two variants within each theory. Second, it examines approaches to integration into modern democratic capitalism. Treating the three theories as substitutes identifies relative strengths and weaknesses; complementarity and partial overlap approaches to integration study the institutional settings within which stakeholder capitalism operates. Empirical outcomes reflect competition between market and stakeholder businesses for participants, with institutional conditions determining the scope of collective action.

The approach aligns three typologies in a unique conceptual arrangement defining the three theories of capitalism: forms of capitalism, potential failures of each form and associated types of goods. The first method examines the internal logic of each theory of capitalism. The second draws on traditional narrative review of references documenting each theory of capitalism and variants together with modern Marxist anti-capitalism.

Three typologies align uniquely with the theories of capitalism, each having two variants. Both variants of stakeholder capitalism are compatible with compassionate capitalism, constitutional government or polycentric governance but not with self-interest capitalism, dictatorship or Marxism. A theory of modern democratic capitalism allocates roles for private, club and social goods with empirically variable mixes occurring across countries. Competition among different types of enterprises provides an empirical test for comparative advantages of stakeholder capitalism. Future research should consider approaches for testing the proposed conceptual scheme in practice concerning capacity to deal with grand challenges, wicked problems and black swan events.

Research approach is limited to logical examination of theories and literature documentation without direct empirical confirmation. The study does not address practical implications for managers and public officials or social implications concerning private incentives, stakeholder cooperation or collective action.

Originality lies in shifting terms of debate about stakeholder capitalism from advocacy of substitute theories to understanding of its relationship to market capitalism and collective action capitalism. Value lies in explaining desirability of theoretical integration of three types of capitalism into a comprehensive framework for modern democratic capitalism.
