Critical infrastructures (CIs) are essential components of the built environment. They ensure the interconnectivity and good operability of any major urban environment. CIs are exposed to several disruptions such as natural events, hazards or threats that may disturb their normal functionality. These disruptions may impact societies not only from a socio-economic perspective but also environmentally. Therefore, ensuring the resilience of CIs is crucial to modern cities. This paper aims to explore the main standards and criteria used to assess the resilience of CIs.

A three-stage systematic review process was adopted to retrieve relevant papers. A total of 44 papers were carefully selected, and the content analysis technique was used to thoroughly analyse the papers.

Results show that researchers’ interest to investigate the assessment criteria of CIs resilience increased after 2004. Further, a total of 28 resilience criteria of CIs were identified, of which the most reported ones are organisational resilience; performance loss, disruption and recovery process; resilience metrics and index; safety, security and risk analysis; societies/communities’ resilience and/or social-equity responsibility; dynamic networks connectivity; resilience through design and structural integrity; and economic resilience.

The findings of this research will serve as a solid foundation for the development of hypothesis for future empirical studies into the development of assessment criteria index for CI resilience. Further, the outcomes will contribute to the ongoing international discussions and debate on the appropriate ways to develop CI resilience.

Occupants are one of the most impacting factors in the overall energy performance of buildings, according to literature. Occupants’ behaviours and actions may impact the overall use of energy in more than 50%. In order to quantify the impact that occupant behaviour has in the use of energy, this study simulated interactions between occupants and the systems present in two actual buildings. The main aim was to compare the deviations due to occupant behaviour with the actual conditions and energy use of the two buildings.

The buildings used as a case study in this research were green buildings, rated according to the Australian Green Star certification system as a 6-star and a non-rated building. The two buildings are university buildings with similar characteristics, from Western Sydney University, in Sydney, Australia. A comparison was performed by means of building simulations among the use of energy in both buildings, aiming to understand if the green rating had any impact on the energy related to occupant behaviour. Therefore, to represent the actual buildings' conditions, the actual data related with climate, geometry, systems, internal loads, etc. were used as input variables in the simulation models of the green and the non-rated buildings. Both models were calibrated and validated, having as target the actual monitored use of electricity.

Occupants were categorized according to their levels of energy use as follows: saving, real and intensive energy users. Building simulations were performed to each building, with varying parameters related with lighting, plug loads, windows/doors opening, shading and air conditioning set points. Results show that occupant behaviour may impact the buildings' energy performance in a range of 72% between the two extremes. There is no significant relationship between the green rating and the way occupants behave in terms of the energy use.

This study intends to show the impact of different categories of occupant behaviour in the overall energy performance of two university buildings, a non-rated and a green-rated building, having as reference an actual representation of the buildings. Additionally, the study aims to understand the main differences between a green-rated and a non-rated building when accounting with the previous categories.

The purpose of this paper is to investigate the role of consumer motivation in the context of the circular economy (CE) through the reuse of fashion products.

A qualitative approach was employed through ethnographic as well as in-depth interviews with nine consumers who buy used fashion products in thrift stores and street fairs in Brazil.

The findings are based on interrelationships and overlaps found in the integration between the three-dimensional consumer motivations to buy second-hand fashion cited in the literature. A framework showing a virtuous circle of motivations involving the consumer in an active role in the CE is proposed as a result.

Limitations include participants’ selection and a single region data collection. Implications aim to help researchers to more fully understand a new and complex consumer behavior in a CE.

By highlighting consumers’ motivations for this kind of commerce, the practical implications of this work are the possibilities to inspire retailers to start second-hand fashion businesses. Also, policy makers can focus on engaging consumers in active roles that foster CE events.

This work is one of the first attempts to show the role of consumers in the CE and their motivations to engage in this active behavior.

This paper aims to analyze the antecedents of two variables concerning the presence of quality certifications in hotel chains: the (ex ante) decision to become a member of the quality system and the (ex post) trend to increase or decrease the number of certified properties. Six hypotheses are posed and tested.

The empirical investigation is carried out on the Spanish Q for Quality in Tourism using a database including 295 hotel chains and 2,727 hotels.

The results evidence the presence of differences in the behavior of hotel chains relative to certification depending on their size, market segment, customer origin and the geographical concentration of their establishments.

This research deepens in how the hotel chain characteristics affect the effectiveness of a quality certification. The consideration of two stages in investment decisions allows the authors to identify differences in the ex ante and ex post decision processes. As a result, one factor (geographical concentration) has been detected as being underrated by managers in the first stage.

Este artículo analiza los antecedentes de dos variables relacionadas con las certificaciones de calidad en cadenas hoteleras: La (ex-ante) decisión de formar parte de un sistema de calidad, y la (ex-post) tendencia a incrementar o reducir el número de establecimientos certificados. Seis hipótesis han sido propuestas y contrastadas.

La investigación empírica ha sido desarrollada en el marco de la marca Q de calidad para el turismo en España usando una base de datos que incluye 295 cadenas hoteleras y 2,727 hoteles.

Los resultados ponen de manifiesto la presencia de diferencias en el comportamiento de las cadenas hoteleras en materia de certificación dependiendo de su tamaño, segmento de mercado atendido, origen de la clientela y del grado de concentración geográfica de sus establecimientos.

El artículo profundiza en cómo las carfacterísticas de la cadena hotelera afectan a la eficacia de la certificación de calidad. Tener en consideración la existencia de dos etapas en las decisones de inversión nos permite identificar diferencias entre los procesos de decisión ex-ante y ex-post. Como resultado, hemos observado que un factor (la concentración geográfica) está siendo infravalorado por parte de os directivos en sus decisiones en la primera etapa.

The purpose of the paper is to explore how collaborations can increase the impact of food sharing platforms, which offer the potential to reduce food waste by facilitating contact between suppliers and consumers. With this comes the need to address the twofold challenge of being digital and having an economic and social-environmental mission. Thus, adopting a system perspective and recognizing stakeholders as part of a value network can maximize the generated impact.

A multiple case study analysis has been conducted on 12 food sharing platforms. Data have been collected through semi-structured interviews, triangulated with internal and external documents and content analysed.

The research outlines the systems of collaboration found in food sharing platforms characterized by two levels of actors (platform players and business players) and five different types of collaboration that can help platforms maximize their impact (boosting the network effect; capturing value; enhancing the business model; extending the type of impact; and scaling up).

The research offers important contributions for the advancement of the field, adding evidence on the opportunities offered by collaborations to generate impact for business and society in the context of the sharing economy and food industry. The research allows to identify the concept of “sustainability-oriented sharing platforms” as a subset of sharing economy platforms characterized by a dual mission and related challenges. From a managerial point of view, the study highlights how designing and implementing collaborations with the stakeholders can increase platforms' impact consistently with the life cycle and short- and long-term perspectives.

Information on scales for measuring dimensions related to consumer concerns over production processes is scarce in the literature. The purpose of this study was to develop a more comprehensive scale for measuring concern over the production process (CPP).

The authors derive the concept based on the results of a bibliographic review, existing certification criteria, an interview with five experts and two consumer focus groups. The authors interviewed 725 frequent beef meat consumers to test the scale.

Statistical tests and purification yielded a final scale with 18 items and six latent variables: animal welfare, traceability, social responsibility, environmental responsibility, legality and sanitation in slaughterhouses. The authors confirmed the nomological validity of the instrument using product involvement as an antecedent construct and attitude related to sustainable consumption as a consequent of CPP.

The research results may lack generalisability. New research avenues are suggested for testing the scale in other cultural contexts and with different groups of consumers and food types.

This study provides insights for cattle ranchers, the industry and the retail sector in formulating communication strategies and product/brand positioning in response to consumer concerns about the production process.

There is no study at present that fully addresses the use of a scale to measure dimensions of production processes. The creation of the CPP scale is a relevant academic contribution that aids in assessing the influence of the environmental dimension in conjunction with other essential constructs.

The purpose of this research is to identify the combinations of factors leading to experience in sustainability reporting by Spanish public universities.

Using a sample of 49 public universities in Spain, this paper identifies the combinations of factors on innovation profile, political and internal factors that explain the different degree of corporate social reporting experience with fuzzy-set qualitative comparative analysis.

The study’s findings are a contribution to existing literature as the results obtained point out three different configurations leading to this expertise, with a combination of different conditions based on innovation profile, political and internal factors. Also, the results reveal new characteristics of sustainable development strategies by universities, such as devoting a specific sustainability reporting section in the university website, creating a sustainability body in the university structure or submitting the sustainability report to external assurance.

This study refers only to Spanish public universities. In the future, new studies can enlarge the sample and analyse country effects and impact of public versus private status of universities on sustainability reporting strategies.

The study’s findings are important for university community, regulators and other stakeholders to start considering the need to somehow promote further sustainability reporting and assurance practices by universities, especially in a context of budget restrictions.

This paper opens up a new line of research on sustainability experience using an innovative methodology (fuzzy-set qualitative comparative analysis) useful with small sample sizes, and provides a complete picture of sustainability reporting by Spanish public universities.

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

This study aims to analyze the relationships between knowledge management, internationalization and ambidexterity, also exploring the influence of these variables on Spanish hotel chain performance. Hypotheses are proposed from the dynamic capabilities and knowledge-management views of the firm.

The research model was tested on a sample of 70 Spanish hotel chains applying variance-based structural equation modeling (partial least squares).

The results show that Spanish hotel chains that use knowledge management processes achieve a greater degree of internationalization and this increases their organizational ambidexterity. This study can also confirm a direct, positive and significant relationship between organizational ambidexterity and performance.

This research shows that knowledge may be considered an essential resource to improve hotel firms’ results. Spanish hotel firms should manage their knowledge to stimulate international activity because this could enhance learning capabilities related to organizational ambidexterity and positively influence performance.

The present paper analyzes relationships between variables that had not previously been analyzed in a single model, including knowledge management, the degree of internationalization of hotel chains, ambidexterity and performance.

This chapter describes a research study in which data about the uses of Facebook by higher education students were gathered simultaneously with measurements of a set of psychological dimensions (personal and collective self-esteem, self-concept, general self-efficacy, satisfaction with social support and with academic life, and several aspects of academic experiences: interpersonal, career, institutional, personal and course satisfaction). The final result of the study is a path model inspired on the structural model proposed by Mazman and Usluel (2010) in which the psychological variables that have a significant influence on the academic use of Facebook were incorporated. A positive total effect of identity collective self-esteem in the educational use of Facebook was found and a negative total effect was found for public collective self-esteem in the educational usage of Facebook (EUF). Institutional adaptation proved to have a significant positive total effect on students’ willingness to use Facebook for educational purposes. Satisfaction with life was not a direct predictor of the educational use of Facebook. However, it was a direct predictor of the use of Facebook for work-related purposes, which was the strongest predictor of educational use of Facebook. Therefore, although the effect of satisfaction with life in the educational use of Facebook was only indirect, it was nevertheless positive and statistically significant.
