The purpose of this paper is to present experimental investigations on the structural behaviour of composite sandwich panels for civil engineering applications. The performance of two different core materials – rigid plastic polyurethane (PU) foam and polypropylene (PP) honeycomb – combined with glass fibre reinforced polymer (GFRP) skins, and the effect of using GFRP ribs along the longitudinal edges of the panels were investigated.

The experimental campaign first included flatwise tensile tests on the GFRP skins; edgewise and flatwise compressive tests; flatwise tensile tests on small‐scale sandwich specimens; and shear tests on the core materials. Subsequently, flexural static and dynamic tests were carried out in full‐scale sandwich panels (2.50×0.50×0.10 m³) in order to evaluate their service and failure behaviour. Linear elastic analytical and numerical models of the tested sandwich panels were developed in order to confirm the effects of varying the core material and of introducing GFRP ribs.

Tests confirmed the considerable influence of the core, namely of its stiffness and strength, on the performance of the unstrengthened panels; in addition, tests showed that the introduction of lateral reinforcements significantly increases the stiffness and strength of the panels, with the shear behaviour of strengthened panels being governed by the ribs. The unstrengthened panels collapsed due to core shear failure, while the strengthened panels failed due to face skin delamination followed by crushing of the skins. The models, validated with the experimental results, allowed simulating the serviceability behaviour of the sandwich panels with a good accuracy.

The present study confirmed that composite sandwich panels made of GFRP skins and PU rigid foam or PP honeycomb cores have significant potential for a wide range of structural applications, presenting significant stiffness and strength, particularly when strengthened with lateral GFRP ribs.

The purpose of this paper is to evaluate the impact of external audit on the management of the Common Fund of the Mozambique National Institute of Statistics (INE).

This paper followed a case study approach of the INE Common Fund that was based on the qualitative evidence from the content analysis of the external audit reports, annual plans of activities and budget for the past seven years and interviews with middle managers of the INE.

The research found that external audit has a relatively significant impact on the management of the INE Common Fund. The authors attribute the positive impact to the high concern of management to implement the external audit recommendations, associated with the financial dependence between the agent (the National Institute of Statistics) and the principal (Fund Donors), explained through Laughlin’s Model of Accountability.

The results indicate that external audit associated with the financial dependence of the agent on the principal has a significant impact on the accountability. Thus, it contributes to assist in the formulation of public policies on external financing to developing countries.

Most of the studies on external audit and accountability are from countries with more developed economies than Mozambique’s, without heavy reliance on external financing, and these studies analyse the audits carried out by public audit institutions. This research explores the phenomenon in the context of external financing to the State Budget by governments and international organisations.

This study aims to understand whether entrepreneurial alertness is a relevant determinant in creating opportunities in the context of small- and medium-sized enterprises (SME).

To this end, qualitative research was undertaken, specifically the case study method. The study context was formed of four SMEs (cases) located in an inland region of Portugal. The data-collecting instrument was an individual interview held with the owners managers of the chosen firms, and the data treatment technique was content and thematic analyses.

The results obtained reveal that entrepreneurial alertness is always present in the SME entrepreneurs/business people’s daily lives and clearly creates good business opportunities not yet observed by the competition.

This study seeks to help SME owners managers to understand the phenomenon of entrepreneurial alertness and understand the importance of this determinant for their firms’ success.

This study is innovative as it helps to characterise and understand entrepreneurial alertness by showing its importance for SMEs in creating valuable opportunities and achieving success.

Start-ups can change the direction of a country's economy when they manage to remain in the market, as they are companies that generate innovation, income and employment. However, these are companies that need both favorable external conditions that guarantee their survival, and internal capacities for the development of a management that is able to consider the needs for change in the product or service and consolidate the business as a whole. Therefore, start-ups need to develop dynamic capabilities (DCs), which are achieved through the processes that direct, coordinate and formulate the strategies of the other processes. Therefore, adopting a management approach that enables the development of DCs is essential for the survival of start-ups. The business process management (BPM) approach becomes an appropriate option, since it identifies business processes to adapt organizational management to new market demands. It can be used to interpret the environment, to understand the organization internally and to transform; it is flexible to the needs and characteristics of each organization. Based on this, the objective of the study is to develop a BPM framework that operationalizes the development of DCs in start-ups.

The method used consisted of two case studies and analysis of documents and seven interviews. Two start-ups that underwent BPM promotion in 2018 and 2020 were selected. The start-ups are Brazilian and from the biotechnology sector. Interviews were conducted with the team that promoted BPM at start-ups and with members of the start-ups that participated in the promotion. The interviews followed a semi-structured script elaborated according to the authors of the literature review. Discourse analysis was used to identify excerpts from the statements that expressed the content of the questions. All interviews were recorded with the prior consent of the participants and later validated with them.

The BPM promotion framework for start-ups is divided into four steps: “frame BPM,” “understand BPM,” “enable BPM” and “continue BPM”. Nine principles constitute the promotion of BPM: (1) context consideration principle, (2) holistic, (3) simplicity, (4) involvement, (5) empowerment, (6) shared understanding, (7) purpose, (8) technological appropriation and (9) continuity. Promoting BPM in start-ups has developed dynamic entrepreneurial and networking capabilities.

As for the contribution to society, scientific studies make it possible to structure tacit knowledge and give direction to human action based on assertive methods; thus, the scientific contribution on DCs and start-ups brings assertiveness to start-up managers and the entire chain they impact with their actions, which makes their performance more beneficial to society.

As for the contribution to the state-of-the-art, visualizing the principles in a practical way, through the application of the BPM promotion project in start-ups, made it possible to understand the BPM cycle in a less rigid and more fluid way. This format proved to be suitable for the start-ups in the case study, as it ensured that they learned both about how the approach works and about the advantages of using it in the management of start-ups, thus contributing to the development of these important organizations for the economy of different countries.

This short communication aims to explore and synthesize the main effects of COVID-19 on the labor market in Portugal regarding the dimensions related to job security and unemployment.

Field research is used to identify and understand the challenges posed by the COVID-19 pandemic to the labor market in Portugal. Data from the National Institute of Statistics of Portugal are analyzed and compared with artifacts published in the field, which allow us to explore the impact of this phenomenon from multiple perspectives.

The findings indicate that the impact on the labor market is very asymmetric regarding geographical regions, sectors of activity, age groups and the nature of labor ties. The most touristic regions and those with a strong dependence on the exterior are the most affected. Young people and women with unstable employment relationships and in temporary work situations are also particularly vulnerable.

This study focuses on an emerging area with a strong impact of the COVID-19 pandemic on the labor market. This study seeks both to identify challenges in the Portuguese labor market and to discuss measures that should be taken to mitigate their effects, such as reforming the social security model, the role of teleworking or the more balanced development of the territory.

The COVID-19 pandemic caused job losses to rise dramatically. Herein, the purpose of the article is to identify which personal and job characteristics make individuals more vulnerable or more resilient to COVID-19 unemployment in Portugal and thus to help policymakers, organizations and individuals themselves, in creating mechanisms to avoid unemployment within this new context.

Using extensive personal and job-related data on the complete population of newly unemployed in Portugal over several months after the emergence of the COVID-19 pandemic, a logit model is estimated to identify the characteristics that make workers more resilient or more vulnerable to COVID-19 unemployment, in comparison with the pre-crisis period.

The COVID-19 crisis is shown to be disruptive by changing the unemployment structure, increasing socioeconomic inequalities and weakening traditional mechanisms of employment protection. Additionally, the authors identify a higher vulnerability of low-skilled individuals and of those in occupations with low working-from-home feasibility and/or from non-essential sectors (particularly tourism).

Policy indications are given aiming to protect the most vulnerable individuals, sectors and regions in Portugal, in this new and unprecedented context.

A seven-month period following the emergence of the pandemic is considered, which allows investigating both the immediate and the medium-term effects of the COVID-19 crisis on job losses. Additionally, by matching data from three different sources, an extensive set of multilevel variables is considered, some of them new in the literature.

The purpose of this paper is threefold: first, to test the role of the managerial team’s commitment to quality deployment, quality performance and firm performance; second, to shed light on the effects of a certified quality management system on this chain; and third, to analyze the effects of changes in this chain on different management team attitudes, namely, innovativeness.

Based on a survey conducted in a sample of 370 hotels from the region of Madrid (Spain), the model and hypotheses were validated using structural equation modeling analysis.

The results reveal the importance of a commitment to quality for quality deployment. In addition, quality deployment has a strong impact on operations and employee and customer performance. However, only impacts derived from customers’ perceptions of service quality affect firm performance. In addition, a contextual analysis was performed to verify whether various contextual factors (certification in a quality management standard and the innovative attitude of the management team) could modify the previously obtained results for the full sample.

The management team should understand that its attitude toward quality management could affect the company’s overall performance. On the one hand, the team should be aware that the cost of implementing quality practices could be a burden for employees in the performance of their daily activities. On the other hand, there is a positive relationship between involvement in addressing customers’ requirements and financial performance. Therefore, a balance between the efforts to maintain a certain level of quality by the firm’s employees and the service quality offered to the customers is crucial to achieving better financial performance.

The impact of the implementation of quality management practices on performance has been widely studied; however, the role of intangible factors has not been commonly discussed in service industries in general and even less so in the hospitality sector. This paper analyses the influence of the quality management team’s attitudes toward innovativeness and the implementation of a quality management standard.

The purpose of this paper is to analyze and compare the existing management system standards in the gastronomy sector.

On the basis of secondary data, the most implemented management system standards within this sector are analyzed, namely, the ISO 9001 focusing on the sector of “hotels and restaurants,” the ISO 22000, the “Q” Spanish tourism-specific standard, and the Michelin stars system.

The results, although descriptive, show the differences among them. Regarding the content, the main difference between the documented management system standards and the Michelin stars system is in the evaluation and certification process, as it is known and planned in the former group but not in the latter. The scope is also different, as the former group refers mainly to the process and the latter to results. The diffusion results confirm the increase in sectoral management system standards.

Although studies analyzing the importance of sectoral standards have been published, this study is one of the first focusing on four different management system standards in the gastronomy sector. Implications for both practitioners and academia are also discussed.

The current expansion of the knowledge economy and its requirements of highly educated workers make interesting to analyse the effects on the labour market outcomes of completing a master's degree. This study examines the factors determining the probability of pursuing a postgraduate programme and observes whether workers reaching this educational attainment reap the benefits of their human capital investment through better paid jobs compared to college-only degree holders. On the other hand, it analyses whether individuals with a master's degree are more prone to upward wage mobility.

The study relies on data obtained from the second survey on the Labour Insertion of University Graduates conducted by the National Statistics Institute (INE, 2019). This survey allows us to observe labour market transitions of the first group of Spanish university graduates under the European Higher Education Area (EHEA) and their earnings. The methodological procedure consists of the estimation of wage models controlling for the unobservable differences between workers who have or have not completed a master's degree.

The results indicate a significant positive impact of master's degree on salaries. Furthermore, individuals with postgraduate studies are more prone to upward wage mobility in comparison to college-only degree holders.

Data used does not allow us to identify which competences associated with the completion of a master's degree are more remunerated by employers.

The econometric specification applied allows us to compute the direct effect of a master's degree on wages and predict the average probability that an individual is in a determined wage interval according to the knowledge area and controlling by the rest of characteristics.

The findings are helpful to diagnose and understand how the knowledge acquired through postgraduate studies are rewarded by the labour market, which is essential to evaluate the return on educational investments when making decisions about whether or not to continue postgraduate studies.

This research addresses novelty aspects on tertiary education in Spain and its effects on workers' careers.

The purpose of the paper was to know and evaluate consumption, preferences and the knowledge of labelling legislation about wild and farmed seafood products.

A sample survey on Sicilian families was conducted through a direct interviews between October 2015 and October 2016 to study the attitudes of Sicilian consumers towards wild and farmed fish and seafood products. A stratified two-stage sampling design was chosen with variable probability of inclusion of the units of first stage and 1,700 subjects were interviewed.

The results obtained showed that the 69.4% of respondent ate fresh fish at least once a week and the 86% of respondents consumed aquaculture products at least once a month. Also, the 77.3% of respondents did not know the current legislation on the labelling. Multiple correspondence analysis allowed to identified three profiles of Sicilian families and binary logit model was used to examine the factors that influenced different frequency of fresh fish consumption in general and farmed seafood products in particular.

Extending the research throughout the Italian territory would have allowed further comparisons at the national level.

The research provides useful information on Sicilian consumers that could be used by policymakers and by marketing communications company.

This research, on a restricted group of European consumers (Sicilian), characterised by living in an island, reinforce the knowledge regarding seafood consumers.

This study used a probabilistic sampling design and a face-to-face questionnaire which produce results more robust in compare to surveys used more frequently such as non-probabilistic sampling design.
