Variables Exploración y comparación de medidas de asociación no lineal por pares para variables continuas ("Exploring and Comparing Pairwise Nonlinear Association Measures for Continuous Variables")
Get PDFExisten numerosas medidas de asociación, tanto lineales como no lineales, entre pares de variables continuas. Estas medidas se utilizan para indicar la fuerza de la relación entre las dos variables. Surge entonces la pregunta de cuál de estas medidas debería emplearse para explorar, en general, las relaciones entre dos variables. La identificación de relaciones lineales o no lineales puede ayudar a evitar problemas en modelos de regresión. El objetivo de este trabajo es examinar medidas alternativas de asociación que podrían utilizarse como reemplazo o en conjunto con los coeficientes de correlación lineal estándar. Los resultados nos llevan a concluir que la medida de correlación máxima es particularmente útil y capaz de detectar asociaciones no lineales entre variables continuas, además de ser relativamente eficiente desde el punto de vista computacional. Puede emplearse tanto en análisis exploratorios como en un marco de regresión moderno
International networks in cultural industries: the case of agencies for opera artists in the immediate post-COVID-19 period
Get PDFThis study presents an empirical investigation into the internationalization processes within the opera performing arts industry, which represents a critical component of the broader creative industries. By utilizing data from Operabase, a comprehensive online database of opera-related information, we employ social network analysis to delineate the network of connections established between nations through the mobility of opera artists, mediated by the agencies that represent them. Moreover, the research assesses the influence of factors such as geographical proximity, cultural affinity, market dominance, and reciprocity on these international networks. Our findings provide a nuanced understanding of the internationalization of opera, emphasizing the significance of geographical proximity, reciprocity, and (partially) tradition/dominance in the opera market as key drivers of global interconnectedness in this domain
Who sets prices better? The impact of pricing agents on consumer negative word-of-mouth when applying price discrimination
No full textPrice discrimination often results in negative emotional experiences for price-disadvantaged consumers. Building on affective events theory, the impact of different pricing agents (algorithms vs. humans) on the negative word-of-mouth (NWOM) was investigated for price-disadvantaged consumers through seven experiments (n = 2080) and a single-paper meta-analysis. The findings revealed that algorithmic pricing led to lower NWOM among consumers. Further analysis suggested that the impact occurs through the sequential mediation of psychological contract violation and cynicism psychology. Additionally, relationship norms and implicit personality moderated the influence of pricing agents on NWOM. This research provides marketing communication strategies for tourism enterprises utilizing algorithmic pricing to mitigate consumer NWOM when implementing price discrimination strategies
Playful pedagogy and gamification: developing reflective practitioners in tourism and hospitality education
No full textIs landscape public?
No full textThis chapter describes how climate action – demonstrations that occupy streets, squares, and even highways – draw connections between landscapes impacted by global warming and public spaces of protest. Building on a combination of fieldwork and critical analysis, the chapter maps a conceptual framework where processes of landscapes (as more-than-human entities) and practices of making public space (as socio-spatial constructions) are connected through direct action (and inaction). The chapter outlines definitions of public space and landscape, recognizing frictions between historic Western European approaches to landscape that undermine more open, accessible, and democratic spaces. Advancing the concept of post-landscape, the research reveals how transnational public spaces can be claimed and represented by adopting techniques of planetary landscapes. This reciprocity between landscape and public space highlights that traditional bounded definitions and spaces of both landscapes and publics can be reframed through an emphasis on processes and practices of continual remaking
The development, delivery, content and impact of nutrition education in prisons: a systematic review
Get PDFPeople in prison are at an increased risk of long-term conditions that have been associated with poor nutrition intake, low levels of physical activity, and obesity. We aim to identify the necessary components of nutrition education to impact the health and health behaviors of people in prison. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines informed the structure of this article. Our protocol was registered in PROSPERO (CRD42022353925). Electronic databases were searched for relevant studies published in the English language from January 1, 2000, to December 31, 2023. Data were extracted and narrative synthesis completed. The search identified 394 studies, of which 10 studies included nutrition education delivered to and with people in prison. In most cases, nutrition was one element of a complex intervention, with the inclusion of physical activity and/or a focus on health. The outcomes measured varied considerably across studies; therefore, our narrative synthesis explored the (1) development and delivery, (2) content, and (3) impact of nutrition education delivered for people in prison. There remains a need for nutrition education for people in prison, developed through coproduction, that encompasses their individual needs, with quantifiable outcome measures through validated tools and/or physiological measures
Argentina’s economic shock therapy Milei’s austerity policies and the road ahead
No full textArgentina’s political and economic landscape has oscillated between neo-liberalism and neo-developmentalism over the past two decades, each model failing to deliver sustained prosperity (Öncü 2024). After the 2001 economic crisis under neo-liberal policies, the country shifted to neo-developmentalism under Néstor and Cristina Fernández de Kirchner. This approach emphasised state intervention, social inclusion, and capital controls, aiming to foster economic growth and reduce inequality. Argentina experienced significant economic growth during the earlier years of the Kirchner governments, achieving average annual growth rates of 8.8% between 2002 and 2007 and 6.3% between 2002 and 2011, driven by neo-developmentalist policies. However, the model’s inability to address structural challenges, coupled with external shocks, led to its eventual decline
Strength of lightweight fibrous modified foamed concrete filled hollow section under pure axial load
No full textThe concrete-filled steel hollow sections have been widely used as columns due to their superior structural performance. The use of concrete in-fill produces higher compressive strength and reduces the buckling of steel hollow sections. Nonetheless, recent studies have primarily concentrated on three types of concrete infill: normal concrete, high-strength concrete, and lightweight aggregate concrete. Lightweight concrete could serve as an alternative to normal concrete, aiming to reduce the dead weight of the concrete infill, such as Modified foamed concrete. Modified foamed concrete, which utilizes minimal water and is considered more sustainable, has garnered significant attention as a potential structural material. However, there has been little discussion on CFHS with modified fibrous foamed concrete. Therefore, this study aims to determine the strength of fibrous-modified foam concrete-filled hollow sections. The foamed concrete infill is modified by adding Rice Hush Ash (RHA) as a sand replacement and using steel and polypropylene fibres to improve its mechanical properties. Experimental work is carried out to evaluate the structural performance of short columns made of modified fibrous foamed concrete-filled hollow section (CFHS). The columns are tested under axial compression load to obtain their ultimate strength. The experiment demonstrates that CFHS with fibrous foamed concrete achieves its theoretical value. The results indicate that incorporating additional fibers increased the ultimate strength capacity by 10% to 13% compared to modified foamed concrete without fibers. This confirms that the addition of fibers significantly enhances the ultimate strength capacity of CFHS. Moreover, quantitative numerical analysis was conducted using ANSYS finite element software. The FEM analysis results closely align with the experimental findings, particularly in terms of load-deflection behaviour and failure modes. Based on this analysis, an empirical model for predicting the columns' ultimate strength was developed, showing strong agreement with the experimental data
A meta-analysis of the antecedents and outcomes of tourist place attachment
No full textPlace attachment is becoming more closely associated with the sustainable development of tourism destinations as tourists increasingly seek quality, unique, and authentic experiences. Numerous empirical studies have explored the antecedents and outcomes of tourist place attachment. However, few studies have reviewed the literature systematically. A meta-analysis of the antecedents and outcomes of tourist place attachment based on 228 empirical studies was conducted. The results show that destination environment, tourist psychology, experience and involvement, and place perception and evaluation can influence place attachment. Place attachment can affect tourist attitudes and behaviors. All antecedents and outcomes included were positively associated with place attachment, but there were variations in the overall associations
The importance of human touch: how robot anthropomorphism impacts customer engagement in tourism and hospitality
No full textAnthropomorphized robots are deployed to enhance experiences in tourism and hospitality. However, it remains unclear how service robot anthropomorphism affects customer engagement. Drawing upon social response theory, this research investigates the effects of robot anthropomorphism on customer engagement and the underlying processes through four experiments (n = 1130) and single-paper meta-analysis. The results indicate that highly anthropomorphized robots are more effective in enhancing customer engagement. Further analysis reveals that this effect is mediated through the sequential pathways of social presence and trust. Additionally, the need for status and social exclusion moderate the impact of robot anthropomorphism on customer engagement. These findings carry significant theoretical and practical implications regarding the utilization of anthropomorphized robots in tourism and hospitality
