The purpose of this paper is to propose an emerging approach in research on school leadership, within the framework of the “International Successful School Principalship Project (ISSPP)”, where one of the three key research strands is “Principals’ identities”.

The paper responds, from a biographical-narrative approach, to knowledge about the impact of the Spanish model of school management on the professional identity of school principals. It analyses the biographical interviews of 15 school principals, through a process of structuring and categorizing the data collected, applying content analysis.

The dimensions of the principals’ identities emerge in different categories: personal identity, professional identity (internal perspective), professional identity (external perspective), social identity, professionalization and dual identity.

The authors studied identities in a project entitled “Successful school principals”, understanding that successful leadership practices largely depend on headteachers’ identities. That is, when the identities are weak and unstable, with a poor identification with the managerial tasks and functions, and not recognised by the teaching staff, the school will probably be unsuccessful. On the contrary, when there are headteachers with a strong professional identity, the authors want to show that there is a positive impact on improvement of results. In the future, in the development of the research project, the authors aim to verify the relationship between headteachers’ identities and educational improvement.

The knowledge gained in our study would enable us to reimagine lines in order to increase the professionalization and identities of headteachers, redesigning work contexts in ways which can strengthen fragile and unstable identities. Finally, the implications of the study in relation to future research can be summarised by the following ideas.

Understanding the world of the lives (lebenswelt) of Spanish headteachers means adopting a hermeneutic approach, observing the self-interpretation comments expressed by the subjects, where the temporal and biographical dimensions occupy a key role. The authors understand professional identity as a socially constructed and personally created experience with its own meanings, feelings and intentions. Therefore, it is logical to use, for data collection, individual interviews which explore the school context and the impact which it has on those subjects who are part of the professional environment. In addition, the authors have the intention of following up the study of identities.

It formulates, first, the theoretical framework for the professional identity from a narrative approach, linked – at the same time – to the practice of leadership, as an interactive relationship with the other members of the school. Successful leadership practices depend to a large degree on strong principals’ identities. Finally, the results are discussed, and future lines are proposed to articulate and strengthen the identity of school principals in Spain.

The importance of nutraceuticals and functional foods has been a topic of interest in nutrition research for many years. This review aims to summarize the findings on the nutritive value and health benefits of chia, as well as its use as a food fortificant.

Published literature on the nutritive value and therapeutic properties of chia has been reviewed.

Chia, an ancient grain, belongs to the mint family (Lamiaceae) and was cultivated in Mexico and Guatemala by the Mayas and Aztecs of a pre-Columbian era. In addition to being gluten-free, chia seeds are concentrated source of omega-3 fatty acids (mainly α-linolenic acid), fiber (insoluble) and polyphenolic compounds (myricetin, quercetin, kaempferol, chlorogenic and caffeic acids), which were found to be comparatively higher than many other grains, cereals and oily seeds. Chia supplementation has potential to lower incidence of cardiovascular disease, obesity, hypertension, cancer, diabetes, pruritus and celiac disease. Because of its nutraceutical and physiochemical properties, chia has been widely used as a whole seed, flour, seed mucilage, gel and oil for developing various enriched food products, such as bread, pasta, cakes, cookies, chips, cheese, yoghurt, meat, fish and poultry.

With advancement in nutrition research, chia would have a great future perspective as feed, food and medicine. However, further research is needed to validate the potential therapeutic effect of chia supplementation on human health.

Earlier in the year, during the national steel industry strike, the House of Lords overturned a judgment of Lord Denning, MR, that sections of the industry unaffected by the trade dispute could be regarded as outside the Act and its amendments and that unions could be restrained in their application of immune activities to those firms. The decision apart, their Lordships in delivering judgment reaffirmed that only Parliament had power to make the Law; it was not the function of Judges to do this, their's to interpret and apply the Law. In strict legal terms and applying to statutes and statutory instruments, this is true; but in the widest sense, judges have been making law for centuries. Otherwise, from whence cometh the Common Law, one of the wonders of the world, if not from the mouths of H.M. Judges. Much of it is now enshrined in statute form, especially Criminal Law, but initially it was all judge‐made. In most systems of human control and function, complete separation is rarely possible and when attempted the results have not been conspicuously successful.

In casting a new look at city; this study interprets the urban form in respect of the role played by human perception of space. The main aim of this research at a macro level is to attain a strong theorical basis through a multi-dimensional approach to the city. The method of analyzing and carrying out a critique of it at an applied level will clarify the impact, which cultural factors have in the formation of urban form. This preliminary recognition and idealism is based on a hermeneutic and deductive method that is particular to the intellectual sciences In the process of devising theories, studying the urban planning texts related to the subject of study and the conclusion from the field study which is carried out in the Isfahan Naghshe Jahan square in the Safavy period played a key role in the research in addition to the goals and questions.

Elaborates on dialogue between Laureates Ragnar Frisch and Jon Tinbergen with regard to an evaluation of their judicious contributions to the science of economics (the two were first recipients of the economic science prize in 1969). Investigates the open conflict between classical and modern modes in reasoning in economics. Gives an in‐depth summation of the lecture by Frisch.

The environmental characteristics of international football can vary significantly from one country to another. As a result, the economic and market possibilities and the objectives of each national league are very heterogeneous. This article aims to examine the differences in revenue structures amongst European national football leagues (n = 50) and cluster them based on these structures. It also investigates which revenue structure would be more effective for similar leagues, considering the previously mentioned varying environmental characteristics of international football.

The study utilises a theoretical framework of business modelling, applied in a unique way to league organisers of national championships. Data on sports and business aspects were collected from sources such as the Union of European Football Associations (UEFA) Financial Benchmarking Reports, transfermarkt.de and related sources for the period 2015 to 2018. K-means cluster analysis, using the Euclidean distance approach, was employed to develop clusters based on revenue sources over a four-year average.

The paper presents the characteristics and year-to-year changes of nine developed clusters. Throughout the analysis, variables such as average overpayment and inequality between player values amongst leagues were prioritised. The study's practical implications can assist league organisers in enhancing the competitiveness of their leagues, supported by short case studies that provide illustrative examples.

The novelty of the current article lies in introducing innovative variables such as the variance of player value whilst focussing on meso-level analysis, providing a fresh contribution to the existing literature in the field for understanding revenue structures and performance in European national football leagues.

This paper aims to study the impact of geopolitical uncertainty on corporate cost of debt and the moderating role of information asymmetry between creditors and borrowing firms.

This study uses 5,223 firm-quarter observations on German-listed firms spanning 2010:Q1–2021:Q4. This study regresses the cost of debt financing on the geopolitical risk, accounting quality and other control variables. Information asymmetry is measured using the performance-matched Jones-model discretionary accrual and the stock bid-ask spread. It uses interaction terms to check if information asymmetry moderates the impact of geopolitical uncertainty on the cost of debts and control for the moderating role of business risk. For the sake of robustness check, it uses long-term cost of debt and bond spread as alternative dependent variables. In addition, this study executes instrumental variables regression and propension score matching to control for potential endogeneity problems.

Estimation results show that geopolitical uncertainty exerts a positive impact on the cost of debt. This impact is found to be more important on the cost of long-term debts. Information asymmetry is found to exacerbate the positive impact of geopolitical risk on the cost of debt. These results are robust to the change of the dependent variable and to the mitigation of potential endogeneity. At high levels of information asymmetry, this impact is more important for firms belonging to “Transportation”, “Automobiles and auto parts”, “Chemicals”, “Industrial and commercial services”, “Software and IT services” and “Industrial goods” business sectors.

Geopolitical uncertainty should be seriously considered when setting strategies for corporate financial management in Germany and similar economies that are directly exposed to geopolitical risks. Corporate managers should design a comprehensive set of corporate policies to improve their transparency and accountability during increasing uncertainty. Policymakers are required to implement innovative monetary and fiscal policies that take into consideration the heterogeneous impact of geopolitical uncertainty and information transparency in order to contain their incidence on German business sectors.

Despite its relevance to corporate financing conditions, little is known about the impact of geopolitical uncertainty on the cost of debt financing. To the best of the authors’ knowledge, there is still no empirical evidence on how information asymmetry between creditors and borrowing firms shapes the impact of geopolitical uncertainty on the cost of debt. This paper tries to fill this gap by interacting two measures of information asymmetry with geopolitical uncertainty. In contrast with previous studies, this study shows that the impact of geopolitical uncertainty on the cost of debt is non-linear and heterogeneous. The results show that the impact of geopolitical uncertainty does not exert the same impact on the cost of debt instruments with different maturities. This impact is found to be heterogeneous across business sectors and to depend on the level of information asymmetry.

This chapter reflects upon the trajectory of research in the geography of tourism in Spain. It begins with a review, including the evolution of the main topics present in the subdiscipline, with a special focus on developments since the 1990s. This is followed by an analysis of the current role and potential impact of academic tourism geography and a discussion on the recent growth in the publication of research results in international journals. Of importance are the institutional factors that explain the increasing recognition of research on the geography of tourism in Spain. Finally, the chapter discusses the hegemony of positivist approaches pivoting on land use, local and regional development, impact analysis, and landscape transformation, as well as the emerging links between Spanish tourism geography and the international mainstream schools of thought.

The proceedings of the 17 editions of the conference of the Spanish Association of Scientific Experts in Tourism constitute a valuable archival resource within the research on Spanish tourism. But so far their contents have not been analyzed. The aim of this chapter is to examine the research that has been presented at its conference by means of a bibliometric analysis of the proceedings of 17 editions. The study focuses on the origin of the research (countries, regions, institutions, and authors), as well as its characteristics in terms of themes dealt with, geographical areas researched, methodologies, disciplinary areas, and attitudes toward tourism. Implications for the evolution of the research are discussed in terms of knowledge contributions and the shaping of major tourism research traditions.

This chapter discusses the findings of a qualitative study conducted on the US–Mexico border to investigate preservice bilingual teachers’ understandings of the effective practices needed to teach content in bilingual classrooms. Specifically, participants’ understandings of teaching language through content to emergent bilinguals and the role of academic language in a content methods course taught in Spanish for preservice bilingual teachers were explored. The results of the study show that preservice bilingual teachers struggled to internalize how to develop language objectives that embed the four language domains as well as the three levels of academic language into their content lessons. Although participants emphasized vocabulary development, they integrated multiple scaffolding strategies to support emergent bilinguals. Moreover, although preservice bilingual teachers struggled with standard Spanish, they used translanguaging to navigate the discourse of education in their content lessons. The use of academic Spanish was also evident in participants’ planning of instruction. The authors contend that bilingual teacher preparation would benefit from the implementation of a dynamic bilingual curriculum that: (a) incorporates sustained opportunities across coursework for preservice bilingual teachers to strengthen their understanding of content teaching and academic language development for emergent bilinguals; (b) values preservice bilingual teachers’ language varieties, develops metalinguistic awareness, and fosters the ability to navigate between language registers for teaching and learning; and (c) values translanguaging as a pedagogical strategy that provides access to content and language development.
