Sustainable Tourism Governance: a systems thinking Triple Helix approach
No full textPurpose – Like any economic sector, the tourism industry encounters growing pressures to achieve a viable balance between economic growth, environmental preservation, and societal welfare. Contemporary strategies for tourism governance frequently place a greater emphasis on economic advancement, thereby overlooking the significance of environmental and social considerations. The objective of this study is to investigate how the multiple actors involved in tourism systems can effectively interact to co-create value by integrating the economic, social, and environmental dimensions of sustainability.
Design/Methodology/Approach – This paper introduces a comprehensive framework inspired by the Viable Systems Approach (vSa) for addressing the challenges of balancing economic progress with environmental and social well-being in the tourism sector. It adopts the VSA framework of the Triple Helix of Sustainability (THS) to highlight the main challenges for effective integrated governance of sustainable tourism systems.
Findings/Results – Maintaining profitability conditions while addressing challenging expectations at both environmental and social levels implies that tourism management addresses a variety of diverse requirements. This variety is further complicated by the involvement of multiple actors characterized by different interests and goals and the transitional and seasonal characteristics inherent to the tourism industry that introduce a certain variability to manage. In such a direction, the study highlights the contribution of the THS, a governance framework that integrates the Triple Bottom Line with the Triple Helix of Innovation, providing guidance for science, policy, and industry actors to make tourism sustainable.
Originality/Value – Developing long-term strategies for sustainable tourism is challenging because tourist systems are multi-actor and constantly changing. Strategic issues like an interplay of multiple different stakeholders, in addition to practical problems like seasonal changes in visitors’ numbers, changing consumer tastes, and global economic trends, can all make it very hard to converge toward sustainable tourism models. Through the THS, systems thinking could support key actors in better catching and understanding the multidimensionality of sustainability and the ways to harmonize the variety to manage.
Research/Practical/Social/Environmental Implications – Effectively integrating the Tourism and Hospitality Sector into the tourism industry requires a deep understanding of complex feedback mechanisms and adapting to dynamic conditions. This adaptation is necessary to ensure economic growth aligns with environmental and social considerations. This study offers guidance to policymakers and organizations responsible for overall governance. It also provides insights to academic institutions and scholars who play a crucial role in envisioning new scenarios.
Limits of the research/future directions – One limitation of this study is the reliance on theoretical literature without empirical studies to supplement it. A potential avenue for future research involves using empirical methods to explore how systems thinking and the THS can be practically applied in real-world tourism governance contexts
A shape preserving quasi-interpolation operator based on a new transcendental rbf
Full text linkIt is well-known that the univariate Multiquadric quasi-interpolation operator is constructed based on the piecewise linear interpolation by |x|. In this paper, we first introduce a new transcendental RBF based on the hyperbolic tangent function as a smooth approximant to φ(r) = r with higher accuracy and better convergence properties than the MQ RBF. Then the Wu-Schaback’s quasi-interpolation formula is rewritten using the proposed RBF. It preserves convexity and monotonicity. We prove that the proposed scheme converges with a rate of O(h^2). So it has a higher degree of smoothness. Some numerical experiments are given in order to demonstrate the efficiency and accuracy of the method
On a new class of positive definite RBFs by using Fourier cosine transform
Full text linkIn this article, we use Fourier cosine transform in order to introduce a new family of infinitely smooth positive definite radial basis functions from completely monotone functions. These bases are represented in terms of positive Borel measures and their Fourier transforms are also given. The proposed theory is used for reconstructing the well-known Matérn RBF and presenting a new positive definite RBF. Numerical results show an accurate reconstruction of the Franke’s function and also mitigating the Runge phenomenon as a key error mechanism
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
