This paper aims to provide an overview of the application of blockchain to agri-food supply chains, including key issues and trends. It examines the state of the art and conceptual structure of the field and proposes an agenda to guide future research.

This article performs a bibliometric analysis using VOSviewer software on a sample of 205 articles from the WoS database to identify research trend topics.

The number of publications in this area has increased since 2020, which shows a growing research interest. The research hotspots are related to the integration of blockchain technology in the agri-food supply chain for traceability, coordination between all actors involved, transparency of operations and improvement of food safety. Furthermore, this is linked to sustainability and the achievement of the sustainable development gtoals (SDGs), while addressing key challenges in the implementation of blockchain-based technologies in the agri-food supply chain.

The application of blockchain in the agri-food supply chain may consider four key aspects. Firstly, the implementation of blockchain can improve the traceability of food products. Secondly, this technology supports sustainability issues and could avoid disruptions in the agri-food supply chain. Third, blockchain improves food quality and safety control throughout the supply chain. Fourthly, the findings show that regulation is needed to improve trust between stakeholders.

The paper provides a comprehensive overview of the blockchain phenomenon in the agri-food supply chain by optimising the search criteria. Moreover, it serves to bridge to future research by identifying gaps in the field.

Foreign markets possess different characteristics to domestic ones; this means that dynamic marketing capabilities (DMCs) should be adjusted. This paper aims to understand how these DMCs enable firms to achieve greater legitimacy in international markets.

This research uses a qualitative approach based on in-depth interviews in collaboration with an association of exporting firms.

Findings suggest five areas of DMCs to improve organizational legitimacy overseas: flexibility, relationship management, local market sensitivity, anticipation and exemplariness. Those capabilities should be combined and will play a different role depending on the implementation phase of the external company. Resource allocation and capability development should follow an integrative approach emphasizing proximity, adaptability, alliances, engagement and credibility to reach differentiation in foreign markets.

The originality is mainly focused on the cohabitation and strong synergies between DMCs and legitimacy. This aspect is particularly relevant because legitimized companies have higher levels of survival, which is fundamental in the international venture.

Banks in emerging markets such as Brazil provide a wide range of services to companies to facilitate the export process. The objective of the present study was to analyze, from the perspective of Brazilian export companies, the relationships between banking intellectual capital (human and organizational), banking agility, banking technologies and company size in banking service provision.

A sample of 318 Brazilian export companies was surveyed with questionnaires. The research model was tested using structural equation modeling, namely the partial least squares (PLS-SEM) technique and SmartPLS.

Banking intellectual capital affects banking service provision, banking agility mediates the relationship between intellectual capitals and banking service provision and technology does not moderate the relationship between agility and banking service provision. The size of the company does not moderate the relationship between intellectual capital and banking service provision.

This work indicates that intellectual capital and the banking agility strategy are critical in the provision of banking service provision for exports.

This work illustrates the effect of banks' intangible resources on the provision of banking services from the perspective of Brazilian export companies.

This study aims to address the global food waste problem in restaurants by analyzing customer sales information provided by restaurant tickets to gain valuable insights into directing sales of perishable products and optimizing product purchases according to customer demand.

A system based on unsupervised machine learning (ML) data models was created to provide a simple and interpretable management tool. This system performs analysis based on two elements: first, it consolidates and visualizes mutual and nontrivial relationships between information features extracted from tickets using multicomponent analysis, bootstrap resampling and ML domain description. Second, it presents statistically relevant relationships in color-coded tables that provide food waste-related recommendations to restaurant managers.

The study identified relationships between products and customer sales in specific months. Other ticket elements have been related, such as products with days, hours or functional areas and products with products (cross-selling). Big data (BD) technology helped analyze restaurant tickets and obtain information on product sales behavior.

This study addresses food waste in restaurants using BD and unsupervised ML models. Despite limitations in ticket information and lack of product detail, it opens up research opportunities in relationship analysis, cross-selling, productivity and deep learning applications.

The value and originality of this work lie in the application of BD and unsupervised ML technologies to analyze restaurant tickets and obtain information on product sales behavior. Better sales projection can adjust product purchases to customer demand, reducing food waste and optimizing profits.

This paper aims to define the efficiency achieved by urban transport companies in Spain concerning the resources they use, considering the type of management used for implementation, public-private, and size.

This study consisted of an analysis of the efficiency of 229 public-private urban transport operators during the period 2012–2021 using Data Envelopment Analysis, the Malmquist Index and inference estimators to determine productivity, efficiency change into Pure Technical Efficiency Change (PTECH), and scale efficiency change.

Based on the efficiency analysis, the authors concluded that of the 229 companies studied, more than 35 were inefficient in all analysed periods. Considering the sample used, direct management is considered significantly more efficient. It cannot be concluded that the size of these companies influences their efficiency, as the data show unequal development behaviours in the studied years.

This study provides arguments on whether there is a significant difference between the two types of management in the urban transport sector. It also includes firm size as a study variable, which has not been previously considered in other studies related to urban transport efficiency. Efficiency should be a crucial factor in determining funding allocation in this sector, as it encourages operators to optimize and improve their services.

The versatility of customer relationship management (CRM) systems has kept these technologies popular over the years. These solutions have been integrated into organizations of all sizes, from large corporations to small- and medium-sized enterprises. Similarly, CRM systems have also found applications in all types of industries and business sectors. All this has been the driving force behind the proliferation of CRM solutions around the world. In this chapter, the author not only reflects on the impact and democratization of CRM systems on business management and marketing strategies but also explores how these technologies can determine the company's income. In particular, the author presents an experiment that analyzes the extent to which the volume of annual investment in CRM solutions can be used to predict annual net income in a sample of companies. Using time series analysis and applying the autoregressive integrated moving average modeling technique, the researcher examines a sample of 10 companies from different industries, and countries, over a 20-year period. The results show the efficiency of the predictive models developed in nine of the 10 companies analyzed. The findings of this study allow us to conclude that there seems to be an association between the investments made in CRM solutions and the income of the companies that invest in these technologies.

A quantitative study sought to better understand responsible leadership (RL) style in the private security sector. The authors analyzed RL’s mediating role in the relationship between rules climate (RC) and employees' perceived organizational support (POS).

The data were collected through an online questionnaire administered to full-time private guards in Ankara (Turkey). A mediation model was proposed, and research hypotheses were tested with structural equation modeling (SEM).

The results indicate a significant positive relationship between the company’s RC and managers' RL, and a positive significant relationship between managers' RL and employees' POS. RL mediates the relationship between company’s RC and employees' POS.

The theoretical framework draws on conservation of resources (COR) theory to consider RL an effective resource. The organization’s RC was a key factor the affecting leader’s responsible behaviors.

This study explores a thriving leadership style, gaining research attention across fields. To the authors' knowledge, no prior research has studied this leadership style in the security sector. The authors use COR to increase understanding of an important antecedent (company’s RC) and consequence (employees' POS) of RL, highlighting this emerging style’s mediating role.

Este artículo de enfoque cuantitativo favorece una mayor comprensión del liderazgo responsable (RL) en el sector de la seguridad privada. Analiza el papel mediador de este estilo de liderazgo en la relación entre un clima de regulación (RC) y la percepción de los trabajadores del apoyo organizacional (POS).

Los datos fueron recolectados a través de un cuestionario online que se administró a guardas de seguridad privados empleados a tiempo completo en la región de Ankara (Turquía). Se propone un modelo de mediación y se comprueban las hipótesis propuestas a través de ecuaciones estructurales con el software (SEM).

Los resultados obtenidos indican una relación positiva y significativa entre el RC y el liderazgo responsable de los superiores, así como una relación también positiva y significativa entre el RL y la POS de los empleados. Se encuentra que el RL media la relación entre el RC y el POS.

Bajo el marco teórico de la Teoría de Conservación de Recursos (COR) se considera que el RL es un recurso altamente efectivo para las organizaciones. El RC de la organización se perfila como un factor clave que afecta los comportamientos del líder responsable.

El diseño transversal del estudio (datos recogidos en un memento del tiempo) y el uso de una muestra de conveniencia son las principales limitaciones del trabajo.

Este estudio explora un estilo de liderazgo aún desconocido, pero con gran potencial, que está ganando fuerza en el ámbito de la investigación científica en los últimos años. Según nuestro conocimiento, se trata del primer estudio que explora este novedoso estilo de liderazgo en el sector de la seguridad privada. El empleo de la Teoría COR favorece la comprensión del RC como un antecedente de este estilo de liderazgo (RL), y también contribuye a comprender la POS de los empleados como clara consecuencia, destacando el papel mediador de este estilo de liderazgo emergente.

The COVID-19 pandemic has significantly impacted global tourism, with international travel bearing the burden of restrictions. Domestic tourism has also faced substantial challenges. This paper aims to analyse the impact of the COVID-19 pandemic on domestic tourism in Spain, focusing on travel from Madrid (the country’s capital) to other tourist destinations.

Mobile phone data has been used to study the evolution of tourist trips over the summers of 2019, 2020 and 2021. Regression models are used to explain the number of visitors at destinations.

The pandemic not only caused a drastic drop in tourist flows but also disrupted the overall pattern of the domestic flow system. Winning destinations were typically areas in proximity to Madrid and less densely populated destinations, while urban destinations were major losers. The preferences of domestic tourists varied notably by income group, but the decrease in trip volumes showed only marginal differences.

The paper demonstrates the potential of mobile phone data analysis to study the uneven impact of external shocks, such as the COVID-19 pandemic, on tourist destinations. This approach considers spatial resilience heterogeneity within regions or provinces. By incorporating income information, the analysis introduces a social dimension to highly detailed spatial data, surpassing traditional studies conducted at the regional or national levels.

COVID-19大流行对全球旅游业产生了重大影响，国际旅行受到了限制的影响最为严重。国内旅游也面临着重大挑战。本文分析了COVID-19大流行对西班牙国内旅游的影响，重点关注从马德里（该国首都）到其他旅游目的地的旅行。

本研究使用移动电话数据研究了2019年、2020年和2021年夏季旅游出行的演变。采用回归模型解释了各目的地游客数量。

大流行不仅导致了旅游流量急剧下降，还扰乱了国内流动系统的总体模式。获胜的目的地通常是马德里附近的地区和人口较稀少的目的地，而城市目的地是主要的输家。国内游客的偏好在收入群体之间有明显差异，但旅行量的减少只显示出边际差异。

本文展示了使用移动电话数据分析研究外部冲击（如COVID-19大流行）对旅游目的地的不均匀影响的潜力。该方法考虑了区域或省份内的空间弹性异质性。通过整合收入信息，该分析为高度详细的空间数据引入了社会维度，超越了传统在区域或国家水平进行的研究。

This paper aims to propose a new method to derive custom dynamic cyber risk metrics based on the well-known Goal, Question, Metric (GQM) approach. A framework that complements it and makes it much easier to use has been proposed too. Both, the method and the framework, have been validated within two challenging application domains: continuous risk assessment within a smart farm and risk-based adaptive security to reconfigure a Web application firewall.

The authors have identified a problem and provided motivation. They have developed their theory and engineered a new method and a framework to complement it. They have demonstrated the proposed method and framework work, validating them in two real use cases.

The GQM method, often applied within the software quality field, is a good basis for proposing a method to define new tailored cyber risk metrics that meet the requirements of current application domains. A comprehensive framework that formalises possible goals and questions translated to potential measurements can greatly facilitate the use of this method.

The proposed method enables the application of the GQM approach to cyber risk measurement. The proposed framework allows new cyber risk metrics to be inferred by choosing between suggested goals and questions and measuring the relevant elements of probability and impact. The authors’ approach demonstrates to be generic and flexible enough to allow very different organisations with heterogeneous requirements to derive tailored metrics useful for their particular risk management processes.
