The aim of this paper is to examine the role of liquidity in asset pricing in a tiny market, such as the Portuguese. The unique setting of the Lisbon Stock Exchange with regards to changes in classification from an emerging to a developed stock market, allows an original answer to whether changes in the development of the market affect the role of liquidity in asset pricing.

The authors propose and compare two alternative implications of liquidity in asset pricing: as a desirable characteristic of stocks and as a source of systematic risk. In contrast to prior research for major stock markets, they use the proportion of zero returns which is an appropriated measure of liquidity in tiny markets and propose the separated effects of illiquidity in a capital asset pricing model framework over the whole sample period as well as in two sub-samples, depending on the change in classification of the Portuguese market, from an emerging to a developed one.

The overall results of the study show that individual illiquidity affects Portuguese stock returns. However, in contrast to previous evidence from other markets, they show that the most traded stocks (hence the most liquid stocks) exhibit larger returns. In addition, they show that the illiquidity effects on stock returns were higher and more significant in the period from January 1988 to November 1997, during which the Portuguese stock market was still an emerging market.

These findings are relevant for investors when they make their investment decisions and for market regulators because they reflect the need of improving the competitiveness of the Portuguese stock market. Additionally, these findings are a challenge for academics because they exhibit the need for providing alternative theories for tiny markets such as the Portuguese one.

The results have important implications for individual and institutional investors who can take into account the peculiar effect of liquidity in stock returns to make proper investment decision.

The Portuguese market provides a natural experimental area to analyse the role of liquidity in asset pricing, because it is a tiny market and during the period studied it changed from an emerging to a developed stock market. Moreover, the authors have to highlight that previous evidence almost exclusively focuses on the US and major European stock markets, whereas studies for the Portuguese one are scarce. In this context, the study provides an alternative methodological approach with results that differ from those theoretically expected. Thus, these findings are a challenge for academics and open a theoretical and a practical debate.

This paper proposes a multicriteria model for risk management to identify and assess risks associated with an integrated management system (IMS). The main benefit of the proposed model is its systemic and logical visualization, which may facilitate the understanding of this proposal’s practical application.

The research design consists of four stages: (1) conduct a literature review to establish risk management models in IMS; (2) collect data concerning risk management models in IMS from a large multinational automotive company; (3) propose a multicriteria model to define and assess risks as well as prioritize mitigation actions and (4) apply the proposed multicriteria model to the data collected in case-based research to evaluate the practical viability of the model to contribute to methods traditionally used.

The results showed that the proposed risk management model contributes to more reliable decision-making in an IMS. The application of the proposed model identified 85 risks in the total processes of the IMS, 31 of which were classified as high risk; thus, priority actions to be taken were defined. The risk classification and prioritization facilitated the implementation of measures to mitigate or eliminate risks, as pointed out by the company managers.

One of the limitations is the fact that specific knowledge is required to maintain and update the multicriteria decision-making tool used in this study. Another one implies the approach to managing risks under the different ISO standards and sector-specific requirements, since this may require updates and customization of the proposed risk management model.

The implementation of IMS in contemporary business environments can be supported by a robust risk management approach. In addition, it provides the leadership with a holistic view of multiple aspects related to a company and fosters continuous improvement.

The social implications of this study are assessed indirectly. This study contributes to the improvement of company management models.

Traditionally, the methods used for risk management in IMS are usually applied independently of techniques such as failure mode and effect analysis. The model developed in this work enables to manage risks continuously to achieve a systemic view of organizational issues and greater transparency of the processes.

The purpose of this descriptive study is to investigate why some elementary children have difficulties mastering addition and subtraction calculation tasks.

The researchers have examined error types in addition and subtraction calculation made by 697 Portuguese students in elementary grades. Each student completed a written assessment of mathematical knowledge. A system code (e.g. FR = failure to regroup) has been used to grade the tests. A reliability check has been performed on 65 per cent randomly selected exams.

Data frequency analyses reveal that the most common type of error was miscalculation for both addition (n = 164; 38.6 per cent) and subtraction (n = 180; 21.7 per cent). The second most common error type was related to failure to regroup in addition (n = 74; 17.5 per cent) and subtraction (n = 139; 16.3 per cent). Frequency of error types by grade level has been provided. Findings from the hierarchical regression analyses indicate that students’ performance differences emerged as a function of error types which indicated students’ types of difficulties.

There are several limitations of this study: the use of a convenient sample; all schools were located in the northern region of Portugal; the limited number of problems; and the time of the year of assessment.

Students’ errors suggested that their performance in calculation tasks is related to conceptual and procedural knowledge and skills. Error analysis allows teachers to better understand the individual performance of a diverse group and to tailor instruction to ensure that all students have an opportunity to succeed in mathematics.

Error analysis helps teachers uncover individual students’ difficulties and deliver meaningful instruction to all students.

This paper adds to the international literature on error analysis and reinforces its value in diagnosing students’ type and severity of math difficulties.

Due to the warming at the automotive market in the last years and consequently the growth of vehicle production has been moved and placed emphasis on the segment. In recent years, some have known, for example, as the earthquake that struck Japan in 2011 was able to disrupt the suppliers of the country. Due to these events, supply chain risk management has become essential to the supply chain operations success. The purpose of this paper is to evaluate the supplier’s systematic selection at the automotive industry compared with the identified models in the literature.

A case study applied at the automotive to propose a method for selecting suppliers considering the risk management.

These results indicate that the organization has established criteria for suppliers selection, this systematic aims to identify the potential risks in the supply chain before the supplier award the project but it’s also the current practice can be improved using as reference the comparative method as applied in this study.

The risk management, a few discussed topic but on the rise among researches, show that the companies, especially those inserted in the automotive segment has been used different techniques for selecting suppliers to focus in a better supply chain control. Establish criteria for selecting suppliers means identifying in advanced the potential risks that the suppliers may offer to the organization during the supply to avoid any interruptions to supply.

This study aims to analyze the extent to which sustainability and its related core aspects have been integrated in the curricula of Business Administration programs in Brazilian federal public universities over the past ten years.

A longitudinal exploratory study, with a descriptive scope, was carried out to evaluate the changes that have occurred in the curricula between the years 2011 and 2021. The analysis focused on the Pedagogical Project of the Business Administration programs offered by the Brazilian federal universities identified in the e-Ministry of Education’s (MEC) database of higher educational institutions and course registration. From the total number of federal universities identified in the e-MEC, about 90% were considered for the research.

The number of courses related to sustainability in Business Administration programs increased considerably in ten years. However, these courses still represent a low percentage of hours in the overall curriculum. Moreover, almost a third of Business Administration programs may produce graduates who have never addressed sustainability during their studies.

This research does not consider other aspects of the curriculum beyond courses, nor does it collect primary data that allows for inferences about the transversal nature of the theme.

This study contributes to monitoring the performance of Brazilian federal universities teaching sustainability and its related core aspects in Business Administration programs. This updated panorama may aid in the search for strategies to expand actions related to education for sustainability (EfS) in educational institutions (EIs).

This study presents some of the impacts of implementing the national environmental education curriculum guidelines. This study encourages discussion about EfS in Business Administration programs and in public EIs, which are important actors for promoting sustainable development.

To the best of the authors’ knowledge, this is the first longitudinal study that maps the courses related to sustainability in Business Administration programs at Brazilian federal public universities. This study offers the first responses to a broad and complex topic, of a region and disciplinary field, of which there are not many studies done, opening doors to subsequent investigations.

Success in the transition between the university and the labor market is an important indicator of the adaptation of newly graduates to the worker’s role in life. This study aims to describe the validity and reliability of the University-to-Work Success Scale based on its internal structure and relationship with measures of career success, protean career orientation and life satisfaction in newly Portuguese graduates.

Using an online protocol, responses were collected from 576 graduates for less than twelve months (74.1% women), aged between 20 and 64 years (M = 25.8, SD = 6.693). Instruments included a socio-demographic questionnaire and measures of transition success, career success and life satisfaction.

The internal structure of the scale was evaluated through exploratory and confirmatory factor analyses that supported a four-factor hierarchical structure with a good fit. The reliability of the factors evaluated by Cronbach’s Alpha was satisfactory. The scale consists of 29 items divided into four subscales (professional insertion and satisfaction, confidence in the future of career, income and financial independence and adaptation to work).

These results support the use of the scale as a valid and reliable measure to assess success in the transition between university and the labor market in newly Portuguese graduates.

This study is very important because this measure can serve as a basis for both preventive and corrective career interventions and policies. The preventive approach can help graduates in their transition to the labor market by promoting career resources. The corrective approach can include re-evaluating organizational integration practices after employment, with an emphasis on promoting gender equality.

The purpose of this paper is to identify the number of courses related to sustainability offered in bachelor degree programs of business administration in Brazilian federal universities.

An exploratory research was carried out based on a descriptive scope. The process of mapping federal universities in Brazil was carried out using data available in the Cadastro das Instituições de Educação Superior (General Register of Undergraduate Institutions), on the Instituto Nacional de Estudos e Pesquisas Educacionais – INEPE (National Institute for Educational Studies and Research) web site. Then, researchers collected business administration curricula from the universities' web sites. The present study was based on 40 of the 45 universities first considered, which represents 89 percent of the programs offered in Brazil. After data collection – performed from July to August 2009 – a qualitative analysis of the curriculum was carried out.

The inclusion of new courses that involve sustainability in business administration programs is still irregular and slow. Of the 40 universities investigated, only 13 (around 33 percent) offered courses related to the topic.

The nature of the research does not allow generalizations regarding other public or private undergraduate institutions.

Results denote a deficiency in relation to the adoption of required courses on sustainability. This gap in the curriculum may compromise the ability of business administration students – who are the future managers and strategists – to reflect on the role of organizations in society.

The present study is the first to examine the teaching of sustainability in Brazilian business education. It also contributes to monitoring the performance of Brazilian federal universities in the teaching of sustainability in business administration programs.

The objective of this chapter is to present the creation of the scientific research project management office at the Ribeirão Preto Medical School, University of São Paulo (FMRP-USP), Brazil. The case is about the adoption of Research Management and Administration (RMA) practices in the largest university in Brazil and presents data for the period of 10 years and relevant increase in the number of projects and budget volume managed (USD 2–21 mi) even with a small team (2–5 people). This is a successful case of a participant of The São Paulo Research Foundation (FAPESP) program and a relevant reference to encourage other Brazilian universities to implement the RMA structure. The implementation of RMA practices is not only possible but can be a game changer in a context with scarce resources and the proper policies can make a difference to the RMA professionalisation in the country.

This research aims to explore perceptions of subjective well-being (SWB) in public relations (PR) practitioners, focusing on dimensions of job satisfaction, networking, relationships and work–life balance, while addressing the under-researched area of gender and age – related to stages of life – disparities in SWB within the PR industry.

Employing a mixed-methods sequential explanatory design, this study utilised a survey, followed by semi-structured interviews to investigate SWB among PR professionals in Portugal, considering gender and stages of life differences.

Using a gendered and stages of life lens, this study found nuanced perceptions of SWB among Portuguese PR professionals. Older women showed higher emotional well-being but lower work evaluations than men, while young professionals exhibited less gender disparities in SWB. Men reported greater job satisfaction, emphasising passion, while women faced challenges like work overload and valued recognition. Gender differences were seen in networking, with men favouring teamwork and women valuing friendships for career advancement. Work–life balance issues, especially among older women, related to mental health.

This study contributes to filling the research gap regarding SWB in the PR industry, particularly in Portugal, offering insights into gender and stages of life dynamics that influence SWB perceptions, thereby informing strategies for enhancing well-being and productivity in PR workplaces.
