Abstract
Purpose
The purpose of this paper is to identify freezing in pitot tubes at real-time, by means of the estimated heat transfer coefficient (HTC) at the tip of the probe. The prompt identification of such freezing is paramount to activate and control mechanisms for ice removal, which in turn are essential for the safety of the aircraft and its passengers.
Design/methodology/approach
The proposed problem is solved by means of an inverse analysis, performed within the Bayesian approach of inverse problems, with temperature measurements assumed available along the pitot probe over time. A heat conduction model is used for describing the average temperature of the pitot tube, which is then rewritten in the form of a state estimation problem. The model is linear and time invariant, so that the inverse problem can be solved using the steady-state Kalman filter (SSKF), a computationally efficient algorithm.
Findings
The results show that the SSKF is fully capable of recovering the HTC information from the temperature measurements. Any variation of the HTC – either smooth or discontinuous – is promptly detected with high accuracy. Computational effort is significantly lower than the physical time, so that the proposed methodology is fully capable of estimating the HTC at real-time.
Originality/value
The methodology herein solves the proposed problem not only by estimating the HTC accurately but also doing so with a very small computational effort, so that real-time estimation and freezing control become possible. To the best of the authors’ knowledge, no likewise publications have been found so far.

Abstract
Purpose
The purpose of this paper is to compare and contrast amenity mixes of innovation districts worldwide and to identify the types of amenities in the districts.
Design/methodology/approach
Urban amenity data were collected from Google Maps as 31,236 points of interest (POIs) in 24 innovation districts. The data were compared and categorised based on the density and diversity of amenity mixes using correspondence analysis. An overall amenity space of the 24 innovation districts was created using correlation and social network analyses.
Findings
This study found that innovation districts have broad ranges of diversity and density. Five groups were identified by correspondence analysis, including retail, foodie, balanced, emerging and health-care districts. The amenity space of innovation districts created using correlation and social network analyses categorised amenities into four broad types – necessary, anchor, vibrant and contextual amenities – based on eigenvector centrality scores and density.
Practical implications
To improve their innovation districts, managers are encouraged to create a foundation of innovations with anchor amenities, to ensure the “live-work-play” environment with necessary amenities, to foster buzz and vibes with vibrant amenities and to strengthen the identity and authenticity with contextual amenities.
Originality/value
Despite some understanding, no previous research has thoroughly analysed the amenities available in innovation districts. This study is the first to comprehensively explore the amenities in innovation districts using data from Google Maps. Place managers can use the method introduced in this research to analyse innovation districts and other kinds of places.

Abstract
Purpose
Although faculty members are regarded as one of the main agents of internationalization in higher education (IHE), research has focused on the upper levels of analysis (e.g. country or educational institution) rather than the individual. The purpose of this paper is to draw from social exchange theory (SET) to examine how the perceptions of costs and expected rewards affect faculty members’ choices of international activities.
Design/methodology/approach
This qualitative study adopted as main methods a review of the literature on IHE and in-depth interviews based on a semi-structured script with an international sample. A sample of 16 researches was selected for interview using the snowball technique of sample selection.
Findings
The authors verified that faculty may seek internationalization in search of job opportunities, greater social approval, greater autonomy and greater security. On the other hand, temporal, monetary, psychological and physical costs discourage faculty members from seeking international insertion. Based on these tradeoffs, our findings suggest that although the basic tenets of SET do apply, the theory does not explicitly address two issues: the fact that costs and rewards are intricately related, and the apparent mismatch between (short-term) costs and (long-term) expected rewards.
Originality/value
This study contributes to the IHE literature by highlighting the crucial role of faculty – that is, the level of analysis of the individual – which has been under-researched and by setting out the reasoning that supports the decision of faculty members to seek (higher) international insertion. Furthermore, this study extends SET as a plausible explanation for the self-internationalization decision by scholars.

Abstract
Purpose
The purpose of this paper is to investigate the role of image and consumer factors in influencing store brand (SB) choice between two retail chains (Carrefour and Extra) in a Latin American market, Brazil. SBs are increasingly offered by retailers in emerging markets. What is less clear, however, is how emerging market consumers make their choices between the SBs on offer from different retail chains.
Design/methodology/approach
A mall-intercept survey conducted by a Brazilian market research company generated 600 usable questionnaires collected in two retail chains. Structural equation modelling was used to test a series of proposed hypotheses.
Findings
The results revealed that SB attitude, SB price-image, store image perceptions, SB perceived value and SB purchase intention have significant and positive direct or indirect effects on SB choice overall, and for each retail chain. However, for price-related constructs, the relationships are stronger for the Extra chain compared to the Carrefour chain. Results show that the Brazilian market presents some departures from both developed and other emerging countries.
Research limitations/implications
Respondents were consumers in only one Latin American market (Brazil) and shoppers of only two retail chains. Caution should therefore be exercised when generalising the results to other markets in Latin America.
Practical implications
Understanding which factors influence consumer choice of SBs in an emerging market while taking into account the presence of different operators allows retailers to launch new SB programs and implement the appropriate strategies to increase SB sales in this market.
Originality/value
The main contribution of this research lies in clarifying consumer behaviour towards SBs in an emerging Latin American market. It fills a major gap in the marketing literature and research in stressing the need to rethink the application of conventional business models to Latin America.

Abstract
Purpose
This paper aims to promote urban–rural synergy in carbon reduction and achieve the dual carbon goal, reconstruct the low-carbon urban–rural spatial pattern and explore planning strategies for carbon mitigation in urban agglomerations.
Design/methodology/approach
The authors propose the idea of land governance zoning based on low-carbon scenario simulation, using the Beijing–Tianjin–Hebei (BTH) urban agglomeration as the empirical research area. Specifically, the authors analyze its spatiotemporal evolution characteristics of carbon balance over the past two decades and simulate the land use pattern under the scenario of low-carbon emission in 2030. Furthermore, the authors create spatial zoning rules combined with land use transition characteristics to classify the urban agglomeration into carbon sink restoration zone, carbon sink protection zone, carbon control development zone and carbon transition agriculture zone and put forward corresponding targeted governance principals.
Findings
The study findings classify the BTH urban agglomeration into carbon sink restoration zone, carbon sink protection zone, carbon control development zone and carbon transition agriculture zone, which account for 28.1%, 17.2%, 20.1% and 34.6% of the total area, respectively. The carbon sink restoration zone and carbon sink protection zone are mainly distributed in the northern and western parts and Bohai Rim region. The carbon transition agriculture zone and carbon control development zone are mainly distributed in the southeastern plain and Zhangjiakou.
Research limitations/implications
The authors suggest restoring and rebuilding ecosystems mainly in the northwest and east parts to increase the number of carbon sinks and the stability of the ecosystem. Besides, measures should be taken to promote collaborative emission reduction work between cities and optimize industrial and energy structures within cities such as Beijing, Langfang, Tianjin and Baoding. Furthermore, the authors recommend promoting sustainable intensification of agriculture and carefully balance between both economic development and ecological protection in Zhangjiakou and plain area.
Originality/value
The authors propose a zoning method based on the optimization of land use towards low-carbon development by combining “top-down” and “bottom-up” strategies and provide targeted governance suggestions for each region. This study provides policy implications to implement the regional low-carbon economic transition under the “double carbon” target in urban agglomerations in China.

Abstract
Purpose
The purpose of this paper is to empirically examine the effects of the attributes of supply chain openness on sustainable supply chain performance (SSCP).
Design/methodology/approach
Data were collected by questionnaire survey from 259 supply chain executives in Pakistan. Structural equation modeling (SEM) was used to test the hypotheses.
Findings
The results indicate that the relative openness of supply chain organizations in Pakistan is very low. Further, all the attributes of supply chain openness have positive but weak association with SSCP. This indicates that there is some awareness of sustainable supply chain but there remains a significant room for improvement with regard to the relationships among different attributes of supply chain openness and SSCP. Pakistani organizations do not fully embrace the concept of supply chain openness in order to achieve SSCP.
Originality/value
The current paper makes three important contributions to the existing literature. First, it empirically examines the attributes of supply chain openness. Second, it contributes to the broader sustainable supply chain management literature by exploring the effects of the attributes of supply chain openness on SSCP. Third, given the limited studies that address sustainable supply chain issues in the context of developing countries, this is one of the few studies that add value to the body of literature in the context of developing countries, such as Pakistan.

Abstract
Purpose
The purpose of this paper is to investigate the influence of consumers’ collectivism and long-term orientation (LTO) cultural values on their purchase intention in relation to environment-friendly products.
Design/methodology/approach
This research adopts a hypo-deductive research design. A unique conceptual model was developed by linking cultural values to key determinants of green purchase behaviour. This model was then tested using a quantitative survey of 682 shoppers in popular Vietnamese electrical appliance stores.
Findings
Analysis using structural equation modelling reveals that consumers with greater adherence to collectivism and LTO tend to engage in green purchase behaviour owing to their positive environmental attitudes, strong subjective norms and tolerance of inconvenience associated with eco-friendly product purchase. Gender is found to moderate the relationship between the determinants and purchase intention.
Practical implications
Marketers including manufacturers and policymakers must endeavour (change globally) to reduce or eliminate perceived inconvenience associated with green purchases. They should also effectively communicate messages stressing that eco-friendly product purchases are crucial for environmental protection and benefit consumer groups including family, peers and society in the long-run.
Originality/value
This research is the first of its kind which links consumers’ cultural values at a personal level to all the elements of the theory of planned behaviour. This research also extends current knowledge about green purchase behaviour in emerging markets by focussing on Vietnam.

Abstract
Purpose
Music and sound have been used pervasively to enhance the tourism and hospitality experience. Incorporating music into a brand’s identity has the potential to influence consumer perceptions and decision-making. This study aims to identify how sonic branding influences consumer attitudes and engagement patterns with hotel brands by using feelings as information theory and applying the effects of music on neurochemical phenomena in the brain. It also explores how sonic branding differentially influences the decision-making of consumer segments.
Design/methodology/approach
Experimental studies are used to examine how sonic brands influence consumer perceptions and engagement tendencies. Study 1 (n = 92) adopts a single-factor experimental design to investigate the main effects of sonic branding (presence vs absence) on customers’ responses. Study 2 (n = 204) uses a 2 (sonic branding: present vs. absent) × 2 (purpose of travel: leisure vs business) design to examine the interaction effects. Participants were recruited through Prolific.
Findings
Results indicate that the use of sonic branding increases engagement tendencies for a hotel brand. In addition, sonic branding interacted with the purpose of travel such that business travelers exhibited more favorable attitudes and higher engagement tendencies toward a hotel brand than leisure travelers when a sonic brand was used.
Originality/value
Given the proliferation of audio-centric environments, this research provides insight into how tourism and hospitality brands can engage and connect with customers by developing sonic brands that can be used throughout the customer journey.

Objetivo
La música y el sonido se han utilizado de forma generalizada para mejorar la experiencia del turismo y la hostelería. La incorporación de la música a la identidad de una marca tiene el potencial de influir en las percepciones y la toma de decisiones de los consumidores. Este estudio pretende identificar cómo influye la marca sonora (o audio branding) en las actitudes de los consumidores y en sus patrones de compromiso con las marcas hoteleras utilizando los sentimientos como teoría de la información y aplicando los efectos de la música en los fenómenos neuroquímicos del cerebro. También explora cómo influye diferencialmente la marca sonora en la toma de decisiones de los segmentos de consumidores.
Diseño/metodología/enfoque
Se emplean estudios experimentales para examinar cómo influyen las marcas sónicas en las percepciones y las tendencias de compromiso de los consumidores. El estudio 1 (N = 92) adopta un diseño experimental de factor único para investigar los efectos principales de la marca sonora (presencia frente a ausencia) en las respuestas de los clientes. El estudio 2 (N = 204) utiliza un diseño 2 (marca sonora: presente frente a ausente) × 2 (Objetivo del viaje: ocio frente a negocios) para examinar los efectos de interacción. Los participantes fueron reclutados a través de Prolific.
Resultados
Los resultados indican que el uso de la marca sonora aumenta las tendencias de compromiso con una marca hotelera. Además, la marca sonora interactuó con el objetivo del viaje de forma que los viajeros de negocios mostraron actitudes más favorables y mayores tendencias de compromiso hacia una marca hotelera que los viajeros de ocio cuando se utilizó una marca sonora.
Originalidad
Dada la proliferación de entornos audiocéntricos, esta investigación ofrece una visión de cómo las marcas turísticas y de hostelería pueden captar la atención de los clientes y conectar con ellos desarrollando marcas sonoras que puedan utilizarse a lo largo de todo el viaje del cliente.

Abstract
Purpose
Previous studies have confirmed the potential benefits of participating in theatrical improvisation, including improved mental health, well-being, skills and strategy development. This study aims to explore the experiences of improv (a subset of theatrical improvisation) for autistic, non-autistic, yet neurodivergent and neurotypical people. In particular, it explores whether participants believe that there have been any benefits from participating in improv.
Design/methodology/approach
Twenty adult participants were recruited using snowball sampling. Semi-structured interviews were conducted and analysed using interpretative phenomenological analysis (IPA) and qualitative content analysis (QCA). IPA explored the autistic lived experience during improv participation, while QCA sought to identify the benefits gained.
Findings
Implementing IPA allowed for the benefits of improv to be embedded into autistic lived experience. This was aggregated into two themes: “life beyond improv” and “social worlds negative impact”. Findings from QCA found five themes: “creativity and opportunities: the arts and workplace”; “acceptance, cognitive flexibility and rolling with it”; “interpersonal, social and communication skills and human connection”; “gains in mental health, quality of life and wellbeing”; and for just autistic participants, “‘I've gone full autistic’ (and can learn why neurotypicals are like they are)”.
Originality/value
To the best of the authors’ knowledge, this is a novel study area that has not been investigated previously.
