In a highly competitive scenario, such as today’s airline business, changes in the regulatory framework may produce important variations in the airlines’ results. An example is the introduction of Sustainable Aviation Fuel (SAF) mandates to help air transport decarbonization. The airlines’ break–even curve provides a useful tool to evaluate the competitive position among airlines and to assess and address the cost impact due to the new regulatory environment. The purpose of this paper is to evaluate the impact of new environmental regulations on airlines’ business results to achieve air transport decarbonization.

Based on the break–even curve and the relationship between fuel cost increment and fuel cost related to the airlines’ operating expenses, the unit cost increment due to SAF introduction is obtained for several scenarios of SAF prices and different airlines.

In many cases, we find that using 100% SAF with prices beyond 1.5 times the present fuel price generates losses: it is not feasible if it is not possible to transfer SAF price to passenger fares due to demand elasticity.

The novelty of this approach is the application of a rationale method to accurately determine the impact of several scenarios of SAF prices on airlines’ business results. This approach also provides a sound and compelling basis to argue before Environmental Regulation Authorities based on facts and figures. This paper is of use and value to airlines, the International Civil Aviation Organization (ICAO), the International Air Transport Association (IATA), practitioners and academics.

This paper critiques the scope of neurotechnologies in significantly expanding the epistemological field of tourism and warns of their potential to undermine the cognitive capacity of tourists to act responsibly and responsively.

This study explores the intersections of neurotechnologies and tourism through an analysis that entails a two-step process: firstly, identifying key themes and debates within neurotourism literature; secondly, critically evaluating these discussions through the lenses of social tourism theory and neuroethics.

Firstly, the work questions the potential of neurotechnologies to significantly expand epistemological boundaries concerning a perennial question in tourism studies: namely, the goal pursued by tourists. Secondly, the paper introduces the framework of an ethics of neurotourism, which can aid in developing the ethical research agenda on neurotechnologies applied to tourism. This framework is used to argue that one of the key risks associated with the use of neurotechnologies in tourism is their capacity to encourage non-responsive and non-responsible tourist behaviour.

Both due to the traditional lack of interest in philosophy in tourism and the pro-business orientation of the tourism academy, critical studies on the relationship between neurotechnologies and tourism are limited. The primary contribution of this work is to underscore that the implementation of neurotechnologies in tourism not only has the potential to foster non-responsible behaviour by undermining tourists’ cognitive capacities to act responsibly, but also can diminish their responsiveness. In a neural context where tourists may already exhibit a reduced inclination towards moral engagement, this reduction in responsiveness can be particularly significant.

The purpose of this study is the synthesis and characterization of a CMYK palette (cyan of Cr-BiVO₄, magenta of Pr-CeO₂, yellow of Bi-(Ce,Zr)O₂ composite and black of YMnO₃) as an eco-friendly polyfunctional palette that combines (a) high near-infrared reflectance (cool pigments) that allows moderate temperatures in indoor environments and the urban heat island effect; (b) photocatalytic activity for the degradation of organic contaminants of emerging concern of substrates in solution (such as Orange II or methylene blue) and gaseous (NO_x and volatile organic compounds such as acetaldehyde or toluene); (c) X-ray radiation attenuators associated with bismuth ions; and (d) biocidal effect combined with co-doping with bactericidal agents.

Pigments were prepared by a solid-state reaction and characterized by X-ray diffraction, diffuse reflectance spectroscopy, photocatalytic activity over Orange II and scanning electron microscopy.

The behaviour of the proposed palette was compared to that of a commercial inkjet palette, and an improvement in all functionalities was observed.

The functionalities of pigments allow the building envelope and indoor walls to exhibit temperature-moderating effects (with the additional effects of moderating global warming and increasing air conditioning efficiency), purification and disinfection of both indoor and outdoor air, and radiation attenuation.

The proposed palette and its polyfunctional characterization are novel.

Achieving good sustainability performance requires balancing higher economic profits with better environmental and social performance. Knowledge plays a key role in improving corporate sustainability performance, but this knowledge is becoming increasingly complex, specific and dispersed among many scientific, technological and business actors. Science and technology parks (STPs) are infrastructures designed to host varying types of organizations that can bring together new, disruptive knowledge. Our purpose is to unveil how these spaces can be drivers of sustainability performance for companies.

We test our hypotheses on a longitudinal database of Spanish companies over the period 2009–2016 using structural equation models (SEMs).

This research confirms that a firm’s location in an STP helps improve its sustainability performance, provided that conditions are optimal in the STP. These optimal conditions are based on an abundance of knowledge spillovers available to the firm and the firm’s ability to harness them, especially those of a more disruptive nature, through absorptive capacity.

Results of this study yield implications for academia in the form of future lines of research and practical implications for policymakers and managers of both STPs and the organizations that host them.

若要取得良好的可持續發展績效，我們必須以更佳的環境和社會績效來平衡更高的經濟利潤。知識在改善企業的可持續發展績效上發揮關鍵作用; 但知識對很多科學的、技術性的和商業的參與者來說，變得越來越複雜、特殊和分散。科技園是為集合嶄新而帶有顛覆性知識的各種不同組織提供軟硬體支援而設計的基礎設施。本研究擬顯露這些設施和場地如何能為企業推動其永續發展績效。

我們以結構方程模式、去測試有關涵蓋2009年至2016年期間西班牙企業的縱向數據庫的研究假設。

研究結果確認了只要在科技園內有最優良的環境和條件，企業在園內的位置是有助改善其永續發展績效的。這些最優良環境和條件是基於企業可得到的豐富的知識外溢，以及它們可透過其吸收能力去控制知識外溢的能力，特別是那些具更強顛覆性本質的知識外溢。

This study investigates the influence of family involvement in firm ownership on the deployment of dynamic capabilities, differentiating between the more structural aspects of family ownership (i.e. ownership dispersion) and the more emotional aspects (i.e. wealth concentration).

We test our hypotheses on a large base of Spanish family-owned tourism firms. The idiosyncratic characteristics of this economic sector, mainly composed of family-owned firms, make it an excellent context for the purposes of this research.

Building on this contextual approach, our study finds that both sides of family ownership have ambivalent effects on the development of dynamic capabilities considering the size of family business.

Competitive pressures force companies to capitalize on dynamic capabilities, as they empower firms to increase their distinctiveness through new products, processes and business management models. However, research remains particularly ambiguous regarding the commitment to innovation and learning capabilities for family businesses, where different aspects of family ownership might alter innovation processes.

The objective of this research is to analyze how omnichannel consumer journey design (OCJD) influences the online customer experience (OCE) and e-satisfaction in consumers' multirooming behavior (searching for information in online and offline channels and purchasing the product online).

The problem-solving theory and experiential marketing perspective are the theoretical background that enables the establishment of five hypotheses. A survey is conducted on multiroomers who had purchased a product online, following an online and offline research journey.

The results showed that OCJD directly and indirectly (through online consumer experience) influences e-satisfaction. Females and younger individuals exhibited higher levels of e-satisfaction.

First, this research analyzes consumers' multichannel search strategies. Second, the consumer journey is incorporated into the study of multichannel retailing. Third, an emergent typology of cross-channel free-riding behavior is analyzed: multirooming.

The purpose of this paper is to analyze how sustainability was operationalized in the Spanish universities through plans and actions that contribute actively to the achievement of the sustainable development goals (SDGs).

A systematic search and content analysis served to examine information available on websites belonging to the 76 universities listed in the Conference of Rectors of the Spanish Universities (CRUE).

The participation of Spanish universities on initiatives focused on sustainability is very limited, highlighting the negligible role of private institutions in which topics like sustainability and the 2030 Agenda/SDGs were scarcely addressed.

The study outlines the actual extent of the inclusion of sustainability in particular co-curricular actions toward the SDGs in the CRUE. The findings enable to define a long-term sustainability road map for the Spanish university system.

This study aims to analyse the influence of football fans' involvement on sponsor brand equity and their purchase intention toward the sponsoring brand. To achieve this, we specified a structural model examining the relationships between engagement, brand equity and fans’ purchase intentions.

The data for this study were collected using a structured questionnaire. Three football teams from the city of Quito (Ecuador) that compete in the first division of Ecuadorian professional football were considered. For data collection, both personal interviews and a web link were used. The personal interviews were carried out directly with the fans of the three teams in the vicinity of the stadiums, prior to matches of the Ecuadorian League.

The study concluded that a greater involvement of fans with a football club positively influences both the valuation of the sponsoring brand and the intention to purchase the product and/or service of the sponsoring brand.

This work contributes to the literature on brand equity. On the one hand, from the companies’ perspective, it is important for brand managers to realise that football fans constitute an especially significant section of the public to strengthen the brand and even to buy the products of the sponsoring brand. On the other hand, from the point of view of the clubs, it should be borne in mind that the involvement of the fans with the clubs constitutes a major factor in strengthening the sponsoring brands.

Most of the research in the literature has studied purchase intention towards the club brand but not towards the sponsoring brand. The research, which is applied to the football industry, conceptually extends the customer-based brand equity (CBBE) model by including the perspective of football fans’ involvement with their clubs.

This paper explores whether, in the context of university–industry (U–I) collaboration, new innovation strategies can be developed through actors' interactions, the exchange of resources and the co-creation of value for and within the system. In the context of the U–I relationship, the innovation perspective can highlight the need to develop strategies that elicit new formulas of value co-creation, which then facilitate innovation as a result of actor collaboration.

A total of 45 public universities in Spain, representing 95% of the total, participated in qualitative research. Personal in-depth interviews with technology transfer officers (TTOs) were conducted by an external firm; in a second phase, two of the researchers conducted eight interviews with the directors of TTOs in those universities with higher rates of transfer.

Findings reveal that enterprises with a technological focus are strengthening their relationships with universities and attempting to build a university business ecosystem by designing strategies for value co-creation such as co-ownership, co-patenting, and co-invention.

The empirical research is conducted in Spain, and results should be interpreted according to this context. Future research should examine new contexts (other countries) to improve the robustness of the data and enrich the results, thus enabling generalization of the management consequences.

The results provide a means to design strategies under a new collaborative and innovating logic. The theoretical framework contributes to theory, with implications for management.
