This paper focuses on prospective teachers’ (PTs) participation in a lesson study (LS) that prompted them to research their own practice. We seek to describe the dimensions of PTs’ knowledge of student learning developed during the process and the LS features fostering it.

The participants were two PTs, a teacher educator, a cooperating teacher and a researcher. The LS was integrated into a Portuguese initial elementary teacher education program. Following a qualitative approach, we used participant observation.

The PTs developed their knowledge of students’ learning of the concept of area in four dimensions: theories; students’ interests and expectations; ways students interact with the content and students’ strengths and weaknesses in learning the concept. To support this development, the LS design considered follow-up sessions and emphasised collaborative work.

This study focuses on PTs researching their practice and disseminating the results, which has been overlooked in previous research of LS with PTs. The results highlight the potential of LS to motivate PTs to research their practice and emphasise the importance of involving them in disseminating LS results.

The primary objective of this study is to analyze the performance and risk characteristics of portfolios composed of Spanish family businesses (FBs) when sustainability and quality factors are taken into account. By comparing different portfolio compositions against a benchmark, the study aims to provide insights into the impact of these factors on portfolio performance.

This study employs an empirical approach to evaluate the performance and risk of portfolios consisting of Spanish family businesses (FBs) by incorporating sustainability and quality factors. It compares the results of various portfolios against a benchmark, utilizing GARCH models and the extended six-factor model of Fama and French for the period 2018–2023.

The findings reveal that investing in Spanish family businesses (FBs) yields higher returns compared to the index, with portfolios incorporating quality factors demonstrating superior performance. However, the inclusion of sustainability factors negatively affects portfolio performance. These results highlight the significance of considering sustainability and quality factors in portfolio construction and investment decisions.

This study contributes to the existing literature by examining the performance and risk implications of incorporating sustainability and quality factors into portfolios of family businesses. The findings offer valuable insights for investors and managers interested in constructing portfolios or developing financial products that balance risk and return effectively.

This paper aims to provide a context for Brazilian Portuguese language documentation and its data collection to establish linguistic repositories from a sociolinguistic overview.

The main sociolinguistic projects that have generated collections of Brazilian Portuguese language data are presented.

The comparison with another situation of repositories (seed vaults) and with the accounting concept of assets is evocated to map the challenges to be overcome in proposing a standardized and professional language repository to host the collections of linguistic data arising from the reported projects and others, in the accordance with the principles of the open science movement.

Thinking about the sustainability of projects to build linguistic documentation repositories, partnerships with the information technology area, or even with private companies, could minimize problems of obsolescence and safeguarding of data, by promoting the circulation and automation of analysis through natural language processing algorithms. These planning actions may help to promote the longevity of the linguistic documentation repositories of Brazilian sociolinguistic research.

Bread is one of the most consumed foods in the world, and its main function is to provide nutrients and energy for the body. Thus, the purpose of this paper was to raise awareness about the consumption habits of bread and consumer preferences in the region of Viseu (centre of Portugal), assessing the extent to which the preferences and consumption habits differ based on individual variables.

The study was conducted by means of a questionnaire by direct interviewing. The questionnaire included sections aimed at gathering information about demographics, consumption habits and preferences related to bread. The sample consisted of 500 consented respondents.

The results showed significant differences between genders regarding the type of bread eaten: women consumed less wheat bread (52 per cent against 62 per cent; p = 0.029) and less unsalted bread (0.3 per cent against 3 per cent; p = 0.023), but more whole bread (25 per cent against 11 per cent; p < 0.001) and more bread with cereal grains (23 per cent against 11 per cent; p = 0.001), thus revealing a trend for a nutritionally more adequate choice. Accordingly, women valued more the composition of the bread when purchasing it (p < 0.001). It was also observed a trend for a lower consumption of wheat bread among classes with more advanced studies (47 per cent on university graduates against 60 per cent on nongraduates; p = 0.004).

This work is innovative because it was the first time the preferences and consuming habits of a sample of Portuguese population regarding bread were accessed, altogether. The results hereby obtained may be of importance both to understand the nutritional importance of bread in the diet of the Portuguese and also for the industry and manufacturers to better correspond to the buying preferences.

The purpose of this paper is to discuss the role of contemporary architecture in heritage protection, reinterpretation and reuse, an issue that has become increasingly relevant due to the recognition of architectural heritage as a key factor for cultural and economic development.

In Portugal, as elsewhere in Europe, cultural heritage management has often been associated with the creation of new museum spaces, namely, within national monuments and archaeological sites. Drawing on restoration theories and international charters, this paper analyses and compares two parallel interventions recently built inside São Jorge Castle, in Lisbon: the Museum Centre (Victor Mestre and Sofia Aleixo, 2007-2008) and the Archaeological Site (João Luís Carrilho da Graça, 2008-2010). This approach offers insight on the complexity of addressing and reconfiguring the profusion of past transformations within a single monument.

These two complementary museum spaces are representative of different attitudes towards heritage appropriation, substantiating the thesis that musealizing always entails the creation of narratives, which translate history and heritage into architectural and curatorial discourses. Besides meeting the functional requirements of specific museum programmes, such interventions frequently deal with the challenge of opening up new perspectives on the past.

Considering the central role of communication in contemporary museums, this paper discusses how heritage musealization can contribute to the translation of historical evidence into updated iconographies, narratives and dialogues. Furthermore, the unique characteristics of this twofold case study can provide an insightful contribution for a broader debate on the reinterpretation of iconic monuments and sites.

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

The main purpose of this paper was to evaluate the influence of the zein coating containing essential oils on the sensory characteristics of sodium-reduced mozzarellas.

Mozzarellas were prepared by dipping in brine containing 5, 10, 15 or 20% of NaCl (w/v) that correspond, respectively, to 25, 50, 75 and 100% of NaCl content used in industry. These salted mozzarellas and another one, unsalted, were coated by an edible zein film added with 3% of a mixture of thyme and garlic essential oils (1:1). They were subjected to sensory analysis in relation to salty taste and overall impression. The mozzarella without salt reduction (20% NaCl w/v), coated or uncoated with the edible film, was also subjected to the analysis of water loss and microbiological quality, in order to evaluate the impact of this film on product quality.

The zein coating added with oils did not compromise the sensory acceptance of the mozzarella prepared with up to 50% of salt reduction. Water loss and microbial growth were lower in zein-coated mozzarella than in uncoated mozzarella. These results showed that this film could be applied as natural additive, contributing to the microbiological and sensory characteristics of the mozzarella.

This paper contributes to reducing the lack of studies in relation to new technologies for food preservation and sodium reduction. In addition, the zein coating containing essential oils can be tested on other food categories.
