Security requirements play an important role in software development. These can be specified both in enterprise architecture models and in business processes. Enterprises increasingly carry out larger amounts of business processes where security plays a major role. Business processes including security can be automatically obtained from enterprise architecture models by applying a model-driven architecture approach, through a CIM to CIM transformation. The aim of this article is to present the specification of transformation rules for the correspondence between enterprise architecture and business process model elements focusing on security.

This work utilizes motivational aspects of the ArchiMate language to model security in the business layer of enterprise architectures. Next, a set of transformation rules defined with the Atlas Transformation Language are utilized to obtain the correspondence of the enterprise architecture elements in a business process, modelled with a security extension of BPMN.

A total of 19 transformation rules have been defined. These rules are more complex than element to element relations, as they take into consideration the context of the elements for establishing the correspondence. Additionally, the prototype of a tool that allows the automatic transformation between both models has been developed.

The results of this work demonstrate the possibility to tackle complex transformations between both models, as previous literature focuses on semantic correspondences. Moreover, the obtained models can be of use for software developers applying the model-driven approach.

The increase in population in the world has brought an overpopulation in various parts of the world, with those cities where their countries are developing being most affected, mainly because these usually have corrupt governments that make urban planning difficult in an optimal way. The increase in the construction of urban areas generates problems in the environment due to the increase in carbon emissions, greenhouse gases, and the extraction of natural resources. Therefore, governments must promote urban innovation based on compliance with sustainable development that allows for preserving the ecosystem and the population's quality of life. Urban innovation must incorporate technologies that allow sustainable activities to be carried out efficiently and monitor the progress of environmental regulations.

An important sector that presents continuous growth year after year and one of the most notable economic sectors worldwide is hospitality and tourism (H&T). For this reason, many enterprises have been created and developed. Each journey could face several challenges, such as economic, social, political, environmental, and technological. This study examines research and case studies about H&T entrepreneurship and provides new insights into the current industry about all aspects that affect entrepreneurship development. Additionally, the impacts of the spread of COVID-19 in the current industry and the changes in the awareness of tourists to enjoy more sustainable tourism that protects the planet during their daily operations are addressed; this being a new opportunity for business so that entrepreneurs can compete in a hypercompetitive market.

Research on college student leadership is evolving, with more scholars studying the influence of social identities on the development of student leaders. The evolving literature includes research on how race influences the leadership identity development of college students, which can support their retention and graduation from postsecondary institutions. Gaps exist in the literature on how the definitions of leaders and leadership influences leadership identity development for many social identities in numerous institutional contexts, including for Latino men. Using a case study methodology, we studied the how definitions of leaders and leadership influenced the leadership identity development of Latino men and how that influenced their placement in the LID model (Komives et al., 2005). Thirteen Latino men in the Southeastern U.S. were interviewed. Participants’ definitions and perspectives of leaders and leadership placed them all in the Leader Identified stage of the LID model. Implications for leadership educators regarding practice and research are provided.

In the academic field of business management, several potential theories were established during the last decades to explain companies' decisions, organizational behavior, consumer patterns, and internationalization, among others. As a result, businesses and scholars were able to analyze and decide based on theoretical approaches to explain the current conditions of the market. Secondary research was conducted to collect more than 36 management theories. This chapter aims to develop the most famous theories related to business applied in the international field. The novelty of this chapter relies on the compilation of recognized previous research studies from the academic literature and evidence in international business.

Science, Technology, Engineering, and Mathematics (STEM) education, its importance, and its difficulties have been defined. This chapter seeks to present the digital tools that have been used during the pandemic period and that have been focused on promoting STEM education at different levels. The efforts made by educational organizations worldwide are mentioned. Different regions are shown presenting the best experiences of digital tools that enhance the elements of STEM and can be extended to different levels of education from elementary school to university. On the other hand, successful experiences of the use of technological tools from the teachers' point of view are shown, depicting the tools that have worked the most during the process of adapting to online classes to devise a much better educational plan that continues to take advantage of digital tools for STEM education.

Food insecurity in the Latin American region has become a complex problem that significantly impacts people's physical and mental well-being. The factors causing food insecurity are varied, ranging from social, political, and economic causes. Ensuring access to food is not a task with limited responsibilities; on the contrary, both public and private institutions must contribute to creating sustainable and innovative solutions. In general, it is necessary to ensure that the food system flows correctly, ensuring the availability of balanced and nutritious food for the diet of the inhabitants of a given nation. Alternative solutions apart from the government's help include sustainable cultivation, finger millet, and close cooperation with the farmers from the agriculture sector. The present research aims to consolidate theoretical information on the Latin American situation and seek the leading solutions of the parties involved.

It is essential to understand how the countries with the highest number of tourist arrivals have managed to recover or not based on the competitiveness of the tourism industry during the pandemic stage. It is necessary to evaluate the policies implemented by each government to maintain the competitive performance of their industries. This chapter proposes a comprehensive review of the policies implemented in the 10 most visited countries according to UNWTO data. Most of these policies are geared toward economic and financial flexibility strategies for companies and individuals in the industry under study. The effectiveness of these policies is evaluated with statistical information extracted from a unified UNWTO database to reduce biases in the effectiveness analysis. Finally, concluding remarks are offered on the effectiveness of the policies and their contribution to the sector's recovery.

In a pandemic framework (COVID-19), this chapter explores the impact of the global economy and socio-cultures concerning three axes: recreational, tourism, and hospitality. Although we slowly see an economic revival, it is well known that this sector of study is very susceptible to being affected by the context of nations. Following restrictions and measures taken by governments around the world to reduce the number of cases of coronavirus infections, many nations closed their borders, affecting international travel and by 2020 tourism had been reduced to the near cessation of operations due to the imminent fear of this poorly studied disease, and the service sector was negatively affected. It should be added that, according to the World Tourism Organization's projections, a decrease of between 20 and 30% is forecast for 2020 compared to the previous year.
