In a global positioning system (GPS) receiver, one of the most time-consuming tasks is to identify and track the visible satellites. The paper aims to propose and examine in detail new and shorter identification patterns or lite pseudo-codes – pseudo-random numbers (PRNs) – that allow GPS receivers to reduce dramatically the computational effort to identify and track GPS satellites. Obtaining lite pseudo-codes is a multi-objective optimization problem that the paper resolves using genetic algorithms (GAs).

The lite PRNs are obtained by using NSGA-II and omni-optimizer multi-objective optimization techniques.

The new PRNs obtained with the proposed single/multi-objective solutions are always better than previously presented when the highest detection peak (DP) is required for the GPS receiver.

Results demonstrate that the problem of “obtaining lite pseudo-codes” is a multi-objective optimization problem. In other words, the solutions obtained with the single-objective approach could belong to a local minimum. The multi-objective approach provides a better solution than the single-objective approach in a 37 percent of the satellites while in other cases the multi-objective approach reaches the same DPs with a similar noise.

The purpose of this research is to analyse the level of knowledge about the Sustainable Development Goals (SDGs) of pre-service teachers in Early Childhood and Primary School Education at the University of Valencia (Spain) and the origin of this knowledge over several academic years, as well as to compare it with that of students of the Degree in Environmental Sciences at the same university.

A questionnaire was designed, validated and administrated to 1,040 students of Degree in Early Childhood Education, Primary School Education and Environmental Science of the University of Valencia to analyse their knowledge of the SDGs and their evolution over three academic years (2019–20, 2020–21, 2021–22).

Statistical analysis shows that most of the participants are either unaware of the SDGs and their importance or have insufficient knowledge of the SDGs and their linkages.

The need to continue promoting teaching resources to favour the implementation of education for the SDG in initial teacher training is highlighted.

Pre-service teachers can become agents of change if they understand the magnitude and complexity of the socio-environmental crisis and get involved through their educational action in the required measures to advance in the construction of more sustainable societies.

This study aims to emphasize the necessary training and involvement of students of the Degree in Early Childhood Education, Primary School Education and Environmental Science at the University of Valencia to advance in the transition to Sustainability.

The purpose of this chapter is to illustrate the contribution made by migrants in the territory that hosts them, particularly when they transfer their knowledge to members of the community. In the specific case of the sea urchin fishery, it is described how the Morishita family in Baja California undertakes the sea urchin value chain, from the location of population banks to the commercialization of the product in the Japanese market and, by therefore, the promotion of development in rural places while starting a culture of export and currency generation. An adventure of opportunities that has been successful for more than 50 years, whose origin is the sustainable use of “a plague” that today is a delicacy for many.

The objective of this study focuses on the characterization of the Latin American entrepreneurial profile from a psychological perspective. In order to do this, a journey through time was carried out in the study of the entrepreneurial subject, from the great classics to the contemporary era, the era of knowledge, innovation, technology, and revolution. In the Latin American context, the role of the entrepreneur is limited due to vulnerable institutions, corruption, populism, and socioeconomic inequity. However, the new information and communication technologies constitute an ideal route for growth in the region. The fundamental element is the psychological profile of the entrepreneur, which is made up of a set of personal characteristics, among which innovation, achievement motivation, self-efficacy, moderate propensity for risk, creativity, perseverance, proactivity, flexibility, locus of control stand out, internal, adaptability, responsibility, ability to recognize opportunities, autonomy, commitment, handling problems and managerial skills. Finally, case studies from countries such as Mexico, Peru, and Chile are presented. It is a documentary study which reflects that Latin American entrepreneurs share the same psychological attributes as those who live in developed countries. However, obstacles arising from the lack of environment and public policies are imposed on entrepreneurial activity. The culture of a country and the formative role of education can become limiting or enhancing factors; therefore, it is necessary to bet on beliefs and convictions attached to innovation, which strengthen the psychological attributes of the entrepreneurial spirit.

Agenda 2030 for Sustainable Development defines 17 goals with 169 targets in economic, social and environmental fields to guarantee human rights. Universities and companies are two driving forces for achieving these Sustainable Development Goals (SDGs). In this context, university research and, specifically, business and management studies should include this new economic-social panorama. Focusing on business and management education, this study aims to analyze who can help to implement the SDGs and how.

A descriptive examination of the evolution of documents and journals on business and management education was performed. Next, a co-authorship analysis, studying the collaboration among researchers, was performed. Finally, a co-word analysis that identifies the main topics and relationships between them was developed.

This study’s results suggest the necessity of expanding collaboration networks between countries and institutions. The analysis also reveals two emergent topics: entrepreneurship and sustainability. Then, three lines for teaching business and management according to the SDGs are proposed: two regarding university-firm relationships – job creation and entrepreneurship – and the third regarding universities effects on society – including sustainability principles and actions in higher education.

The main contribution is to show the important role that universities, in general, and business and management education, in particular, play in achieving the SDGs. Universities must mobilize their managers, professors and students because implementing the SDGs is possible through coordinated and integrated participation.

The purpose of this paper is to analyse if citizens’ searches on the internet coincide with the services that municipal websites offer. In addition, the authors examine municipal webpage rankings in search engines and the factors explaining them.

The empirical study, conducted through a sample of Spanish city councils, contrasted if the information that can be found on a municipal website fits with citizens’ demands. This has been done by comparing the most-searched keywords with the contents of municipal websites.

A positive relationship between the supply and demand of municipal information on the internet has been found, but much can still be improved. Analysed administrations rank the basic data of the organisation, as well as some of the fundamental competences thereof, at the top in search engines, but the results are not entirely effective with some keywords still highly demanded by citizens, such as those related to employment or tourism. Factors explaining internet ranking include the number of pages of the municipal website, its presence in social networks and an indicator designed to measure the difficulty of ranking the municipal place-name.

The results obtained from this study provide valuable information for municipal managers. Municipal websites should not only include information in which citizens are interested, but achieve accessibility standards, have a responsive web design, and follow the rules of web usability. Additionally, they should be findable, which also requires improvement in terms of the design of the municipal website thinking in search engines, particularly in terms of certain technical characteristics that improve findability. A municipal website that wants to have a good positioning should increase its contents and attain the maximum degree possible of visibility in social networks.

This research aims to provide evidence of the impacts of market orientation, customer value approach (through prestige, value for money and reputation for quality) and innovation on museum sustainability.

The model is analysed through partial least squares (PLS-SEM), using a sample of 549 European museums.

The results reveal that reputation for quality, prestige, innovation and value for money positively and significantly influence museum sustainability. Interestingly, the most meaningful linkage is between market orientation and innovation.

This research helps museums that need to increase their customer value and innovativeness so as to ensure museum sustainability. It proves that museum managers have to increase employees’ involvement in decision-making processes.

By using a wide sample of European museums, this study suggests that museum managers need to consider the impact of marketing strategies and customer value perceptions on the economic and social sustainability of museums.

First, the paper examines the extent of environmental disclosures (EDs) made by the Malaysian local governments (LGs) on their websites. Second, it examines the patterns of disclosure with the aim of investigating the underlying motive behind the EDs.

A descriptive content analysis was employed to measure the EDs. A disclosure instrument, based on the extant studies, is designed to facilitate the measurement process.

The results suggest that LGs of various levels, have taken the initiative to report EDs on their websites even in the absence of any statutory reporting regulations either by the state or federal government. Differences in the types of EDs are also apparent and consistent with the premise of legitimacy theory.

A paucity of prior studies measuring EDs made at the LG level is observed in the literature. Research evidence focussing on the EDs reported on the websites is even more scarce. This lack of research contributes to a limited understanding on the development and challenges of the environmental reporting practices within the developing country's perspective. Moreover, generalising the findings of studies conducted in developed countries may not be possible due to a number of regulatory, political and socio-economic factors.

Nowadays, there is a strong public interest in promoting transparency to be informed about the actions of the public sector. At the same time, there has been a significant change in society’s perceptions and concerns about sustainable development, with a marked increase in attention to this area. In this context, our main objective is to investigate the impact of transparency practices in local government on the implementation of the Sustainable Development Goals (SDGs) in Spanish municipalities.

We will analyse a sample of 84 municipalities, using the Dynamic Transparency Index published by Dyntra to measure transparency. For the level of implementation of the SDGs, we will use an index specifically created using data from the report “The SDGs in 100 Spanish Cities”, published by the Spanish Network for Sustainable Development in 2020.

Municipalities with a larger dependent population tend to achieve higher SDG levels. Municipalities with lower financial surpluses and more self-generated resources show better SDG implementation. Progressive political parties lean more towards sustainability, and coalition governments show higher SDG implementation than majority governments. Gender appears to play a minor role in SDG implementation, but male leadership is associated with higher levels. Factors such as population density and government transfers do not have a significant impact on SDG implementation levels.

This study seeks to address the lack of empirical research on the potential impact of transparency on the achievement of the SDGs, while also taking into account other socio-economic, financial and political aspects of the municipality. In doing so, it also contributes to the limited empirical literature on the determinants of the level of SDG implementation in local governments.
