The shift toward a circular economy (CE) represents a collaborative endeavor necessitating the presence of efficient frameworks, conducive contexts and a common comprehension. This research serves as a pivotal stride towards this goal, presenting an exclusive prospect for the investigation and fusion of these frameworks, with particular emphasis on the Quintuple Helix Model (5HM), into a unified theoretical framework that underscores the core principles of the CE. This study is centered on three pivotal questions aimed at decoding the CE transition in specific regional settings.

Adopting an abductive approach firmly anchored in a two-stage qualitative process, this study specifically merges the foundational principles from institutional theory, entrepreneurship literature and CE frameworks to provide insights into the dynamics of circular ecosystems, with a specific focus on the Huelva region in Spain.

The findings demonstrate significant potential in the CE, ranging from the integration of product and service systems to innovations in eco-industrial practices. Yet, a notable deficiency exists: the absence of institutional entrepreneurs, highlighting the essential role that universities can play. As recognized centers of innovation, universities are suggested to be key contributors to the transformation toward a CE, aligning with their societal and economic responsibilities.

This study highlights the importance of managing relationships with entities like SMEs and policymakers or academia for effective CE adoption. Policymakers can refine strategies based on the research’s insights, while the impact of university-driven circular ecosystems on sustainable societies is another crucial area for research.

The sustainability models cited in CE literature may not be comprehensive enough to prevent problem shifting, and it can be argued that they lack a sound theoretical and conceptual basis. Furthermore, the connections between sustainability objectives and the three levels of the CE operating system remain vague. Additionally, there is insufficient information on how regions foster the involvement of the environment in fivefold helix cooperation and how this impacts the CE.

The purpose of this paper is to understand the profile of the Andalusian population in relation to the motivations that support family care for older people, considering multiple sociodemographic and classificatory variables, such as sex, age groups (18–29; 30–44; 45–59; 60 or older), caregiving experience, as well as their general opinions regarding care and decision-making related to it.

A quantitative study is presented to know the opinion of the Andalusian population regarding the motivations that support the family care of older people. The sample comprised 774 participants (18 years or older).

The results show that the majority of the Andalusian population believes that the reason why families care for older people is that it is considered a moral obligation, regardless of the resources available to them. Thus, two population profiles have been found to explain these beliefs. The first profile is made up of current or former caregivers who are 60 years of age or older; and the second profile is made up of people who believe that the family should be primarily responsible for caregiving, who are or have been caregivers and who believe that in the future, the family trend in caregiving will not be modified.

The value of this research lies in the implications of “family care” and “resources and motivations to care” studies today.

The purpose of this study is to evaluate how Qatar Airways’ sponsorship of FC Barcelona affects Qatar’s sports diplomacy and brand awareness. It focuses on the sponsorship’s demand strategy and takes into account the opinions and attitudes of Spanish nationals toward Qatar and Qatar Airways.

To assess this, a survey of 434 Spanish nationals from 17 different regions from four zones (North, South, Center, and East) in Spain between November 3, 2022 and November 21, 2022 was conducted using a strata sampling method.

We argue that Qatar Airways’ sponsorship of FC Barcelona serves to improve Qatar’s recognition and national reputation in Spain. We also found that there is a need for consistent sponsorship and marketing efforts in sports diplomacy to better fulfill public diplomacy aims. Overall, this paper concludes that Qatar Airways’ sponsorship of FC Barcelona positively contributes to the country’s sports diplomacy despite significant challenges.

The major contribution of this study to the literature is the discussion of the role of sports sponsorships in the recognition of the sponsor, which was assessed through conducting a quantitative analysis of public opinion in the sponsored team’s host country.

This paper aims to view the tradition of the Prophet in zakat payment, especially the attributed measurements, and adapt these measures to current zakat measurement practices.

This study is designed with an exploratory sequential mixed method where qualitative data were collected from historical archives and also from the measurement of available ṣāʿ صاع and mud_ مد. These standard measures were collected from Malaysia and other Muslim countries and calibrated at the National Measurement Standards Laboratory (currently carried out by the National Metrology Institute of Malaysia). The volume of the ṣāʿ were tabulated, charted, analyzed and determined.

Prophet Muḥammad ordered for zakat al-fiṭr زكاة الفطر to measure the crops using ṣāʿ (gallon: volume measure), not raṭl رطل (pound: standard weight). This paper recommends a reference volume for the ṣāʿ, and from this value, the volume for the smaller measure mud and much larger measure wasq وسق were calculated. The agricultural niṣāb (5 wasq) is one of the key parameters in ṣāʿ volume analysis.

This study covers standard measures acquired from Malaysia, Saudi Arabia and the United Kingdom (traceable to India). Several empirical data are attained from previous studies from Saudi Arabia and North Africa. Also, some theoretical data are obtained from kitab tafsir, hadith and kitab turath (books and records written by early scholars). A concern in this study is the ratio of de-husked grains currently approximated at half of un-hulled grains. This might not necessarily be accurate and may differ by different types of grains.

After the introduction of the modern measurement system known as the International System of Units (SI) in 1971, ṣāʿ became obsolete, leaving each state in Malaysia to define and convert ṣāʿ to SI units variously. This paper contributes to standardizing the conversion to one value with an appropriate SI unit, that has traceability to the Prophet’s ṣāʿ. This national reference standard ṣāʿ is essential for zakat al-fiṭr measurement, important for zakat centers and impacting every Muslim in Malaysia. Often overlooked, ṣāʿ is more crucial as a basis in determining and standardizing the seasonal crops niṣāb, unfolding the reasons why the poor are paying the paddy zakat in Malaysia.

The Prophet’s tradition for ablution is to use water not more than one mud, this is aligned with the 12th Sustainable Development Goals by the United Nations which promoted the responsible consumption of water. Considering half (adults) of the 1.9 billion Muslims in the world, multiplied by 5 times of prayer, the Muslims will at least use 4.75 billion muds of water for ablution alone in 1 day. This is approximately 3.5 billion liters of water daily, and if they limit their water usage to 1 mud for each ablution, they collectively will save at least four times more water (about 14 billion liters) daily than performing ablution from a running tap. Though for ablution, accuracy is not an issue, the mud impact on all Muslims is vital on a daily basis, literally by volume.

Ṣāʿ is essential in measuring food for the annually obligated zakat al-fiṭr and more crucial as a basis in determining the seasonal crops niṣāb. This paper contributes to the development of a national reference standard ṣāʿ for Malaysia that has traceability to the Prophet’s ṣāʿ.

Within the framework of EU policies and measures to develop a just and fair green energy transition model. This paper aims to offer valuable insights into a paramount concern not so well debated in the literature, i.e. the spatial variation of energy poverty.

This empirical analysis investigates the regional variation of energy poverty we draw on a sample of more than 300,000 Spanish households, extracted from the Spanish Household Budget Survey (HBS) for the period 2006–2022. To characterize the probability of a household finding itself in a situation of energy poverty the authors use a discrete choice univariate probit model.

The results confirm that energy poverty is a phenomenon that is asymmetrically distributed across Spain, and mainly occurs in un-densely populated regions. In addition, the findings demonstrate that the incidence of energy poverty drivers is highly heterogeneous across regions.

The paper ends with some recommendations for policymakers suggesting that countries need to design an energy poverty policy for the households that jointly pursue both a correct identification of vulnerable groups and a match with the type of measure to the characteristics of each region.

This study enhances previous research by considering the case of areas at a lower level of aggregation (i.e. on the NUTS two regions in Spain called autonomous communities) and offers the opportunity to tailor policies to those regions most in need. Furthermore, to provide a more realistic picture of the complex phenomenon of energy poverty, the authors use the information for the period 2006–2022 differentiating by economic micro-cycle. This timespan allows the authors to understand the dynamics of energy poverty in periods of economic crisis, including the effects of the 2008 crisis and the present global energy crisis.

This chapter in its first part analyzes the Leader approach in terms of concept, constituent elements, application, and its contribution to rural development and rural entrepreneurship. In the continuation of the text, authors analyze the application of this approach in Serbia, looking at the activities of the ministry in charge and the views of local action groups (LAGs)’ managers on this matter. The aim of this chapter is to present the results and problems Serbia has seen so far in the implementation of the Leader approach for development of rural areas on a local level. The results indicate that the lack of systemic and continuous state support resulting, among other things, in the lack of a financial portfolio for the LAGs, is the main cause of low local entrepreneurial initiatives and projects implemented within the Leader approach. Future steps in the implementation of this approach in Serbia will depend on financial support for the LAGs from all levels of government, as well as from the possibility of using funds within the EU pre-accession assistance for rural development. Also, it will be necessary to launch larger innovative and entrepreneurial initiatives both by LAGs’ managers and all stakeholders involved in local rural development.

This study aims to explore the Facebook communication strategies of Spanish hospitals during health emergencies, focusing on their role in crisis management and public information dissemination.

Automatic topic modelling and deep learning sentiment analysis were applied to analyse 151,738 posts from 274 hospital Facebook pages (March 2020–Feb 2022). Regression analyses were used to explore the relationships between topics, sentiment scores and hospital characteristics.

The analysis revealed nine main topics, with the three most prevalent related to COVID-19: vaccine information, security measures and situational updates. This indicates that Spanish hospitals significantly relied on Facebook to manage the emergency. The communication strategies dynamically adapted to the intensity of the pandemic and varied across hospital types. Sentiment analysis showed a negative tone for posts about security measures and situational updates. These findings align with the Agenda-Setting Theory, suggesting that hospitals influenced public discourse. Vaccine information posts were more positive, resonating with the Uses and Gratifications Theory by fulfilling the audience’s need for reassurance and guidance.

Using replicable machine learning techniques, this study elucidates the communication strategies employed by Spanish hospitals to manage healthcare emergencies, such as the COVID-19 pandemic. It highlights factors that potentially influence these strategies and provides theoretical justifications for them. The variation in communication strategies on Facebook among different hospital categories underscores the imperative for stricter guidelines and regulations to guarantee consistent and reliable communication during emergencies. This research provides valuable insights for practitioners and policymakers aimed at developing effective health communication strategies on social media.

Money management practices among couples from 27 countries were studied to understand how they reflect egalitarian values. The welfare system was used as a classification criterion, to account for the distinct socio-political contexts in which couple relationships are formed.

The data are sourced from the 2012 Survey on Family and Changing Gender Roles of the International Social Survey Programme. The analytical strategy used has been binary logistic regression.

The results demonstrate that participation of the woman in the household economy and financial decision-making indicates higher levels of egalitarian values in the couple. Couples who distinguish between a common fund and individual funds demonstrate more egalitarian values than those who have only a common fund. Besides, symmetry in the couple in terms of the income level of each partner increased the probability of having more egalitarian values. Greater equality was found among couples who resided in countries with a Mediterranean welfare system.

The paper makes an original contribution to the field of sociology and social policy by focus on couples' money management and improve understanding of the finance-well-being nexus.

This study aims to examine the impact of halal tourism governance on halal tourist satisfaction by using halal tourism branding as a mediating role to increase tourist satisfaction.

Data is obtained through a questionnaire completed by 400 tourists who have traveled to visit halal tourism destinations on Madurese Island. The collected research data is tested by using partial least squares structural equation modeling (PLS-SEM).

The study revealed that halal tourism governance has positive and significant impact on halal tourist satisfaction and halal tourism branding. The study also revealed that halal tourism branding has no positive and significant impact on halal tourist satisfaction because the community thinks that halal tourism branding is common and commonplace.

This research is on an Island-specific halal tourism destination, which means that the findings cannot be generalized to other geographical areas which have diverse cultures.

The study provides insight into halal tourism and destination governance, which is important for marketers, the Ministry of Tourism and local tourism officials to support halal tourism.

This paper fills a gap by presenting the first comprehensive overview of halal tourism governance that enhances ongoing discussions in the halal tourism field.

This study aims to investigate the interplay between a proactive attitude towards disruptions – supply chain disruption orientation – and supply chain resilience, increasing our understanding of their influence on reducing the impact of supply chain disruptions within the B2B context.

As unexpected disruptions are closely related to a dynamic and changing perception of the environment, this research is framed under the dynamic capabilities lens, consistent with existing resilience literature. The authors used partial least squares-path modeling (PLS-PM) to empirically test the proposed research model using survey data from 216 firms.

Results show that a proactive approach to disruptions alone is insufficient in mitigating their negative impact. Instead, a firm’s disruption orientation plays a crucial role in boosting its resilience, which acts as a mediator, reducing the impact of disruptions.

This paper sheds light on the mechanisms by which firms can mitigate the effects of supply chain disruptions and offers insights into how certain capabilities are needed so that firms’ attitudes can effectively impact firm performance. This research thus suggests that dynamic capabilities, traditionally perceived as being enabled by other elements, act themselves as enablers. Consequently, they have the potential to translate strategic orientation or attitudes into tangible effects on performance, enriching our understanding of how firms combine their internal attitudes and capabilities to achieve sustained competitive advantage.
