This paper aims to provide an approach to print shell-type objects using a 5-axis printer. The proposed approach takes advantage of the two additional printer degrees of freedom to provide a curved layer path planning strategy.

This paper addresses curved layer path planning on a 5-axis printer. This printer considers movements along the three usual axes together with two additional axes at the printing table (rotation and tilt), allowing to build more complex and reliable objects. Curved layer path planning is considered where polygons obtained from the slicing stage are approximated by linear and cubic splines. The proposed printing strategy consists in building an inner core supporting structure followed by outer curved layers.

The curved layer path planning strategy is validated for shell-type objects by considering a 5-axis printer simulator. An example with an aeronautic object is presented to illustrate the proposed approach.

The paper presents an approach to curved layer path planning on a 5-axis printer, for shell-type objects.

This study aims to improve our understanding of violence, focusing on the analysis of the relation between socioeconomic factors and homicide rates from 2005 to 2019 in Brazilian capitals.

Multilevel Poisson models were used to estimate the homicide risk in men and women. The response variable was the homicide rate. Fixed effects were estimated for age group, year and gross domestic product (GDP).

The average homicide rate over the 2005–2019 period was 5.83/100,000 and 83.72/100,000 for women and men, respectively. In both sexes, the homicide rates increased over the period. The highest mortality rates were observed in North and Northeastern capitals. The peak homicide rates were 2010–2014, the risk of homicide decreased as age increased, and the capitals with GDP lower than US$5,000 showed a greater homicide rate.

Brazil remains among the countries with the highest risk of homicide, especially in the north and northeast regions, where socioeconomic conditions are more unfavorable. The improvement of socioeconomic conditions may contribute to changing this situation.

This paper aims to examine the relation between firms’ political connections and corporate social responsibility (CSR) reporting in Portugal. The authors argue that in settings where the existence of political connections are viewed as damaging collective interests of stakeholders, political connected firms can deal with legitimacy issues from such connections by resorting to CSR practices and the reporting thereof.

Using archival data from a panel sample of 36 firms from Portugal between 2009 and 2012, the authors examine the relationship between political connections and CSR reporting by way of regression analysis.

The authors find a positive relationship between political connections and CSR reporting.

This study draws on legitimacy theory to highlight that CSR can be used to deal with stakeholder activism and vigilance pertaining to suspicion related to the existence of political connections.

This paper presents a method used to validate a spatial load forecasting model based on fuzzy systems implemented in a Geographical Information System. The validation process confirms the adequacy of the rule base, and also it is strictly necessary to define the confidence intervals associated to the predicted spatial demand.

Purpose: This chapter focuses on the relations between aging and the perception about the families’ quality of life in a medium-sized Portuguese city. Departing from the descriptions of individuals living with at least one child under 14 years of age, particular emphasis is put on how young adults perceive and incorporate into their speeches the presence and role of non-cohabiting elderly, namely their parents and in-laws, as an expression of the quality of life they experience.

Design/methodology/approach: Data rely on episodic interviews conducted with both men and women with young children (3–14 years old), within a broader sociological research devoted to the study of family rituals. The data collected was analyzed using qualitative techniques of content analysis with the help of NVivo software (QSR). The data is presented recurring to contextualized narratives.

Findings: Data analysis allows to conclude that geography matters in the perception that young adults have when reflecting upon the role of the elderly surrounding them, either their parents or in-laws. The presence and coexistence of generations are perceived as “priceless,” a “fortune,” and a “privilege,” possible in a medium-sized city, where everything is close enough to thicken the informal intergenerational solidarities between grandparents, parents, and grandchildren. Behind the scenes, data, furthermore, discloses unpredictable tensions arising mainly regarding children’s education, rules, and behavior.

Originality/value: This chapter contributes to shed light into the daily life of elderly people who are still independent and active, and the seemingly invisible presence and unimportant role they play in their children and grandchildren’s lives.

Examines the tenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

This study aims to improve the reception and positioning of materials in the warehouse, as well as the internal logistics of a bus manufacturing company by acting upon the processes of supply line management.

This study is based on the action research methodology which, through a practical approach, intends to generate transferrable knowledge to other organizations whose situations are similar to that of this study. The practical actions and the knowledge acquired co-create the changes needed for the improvement processes.

Through these improvements, it is possible to standardize supply and eliminate the retention of picking carts on the line, simplify the management of materials provided in supermarket boxes, improve the control of materials and facilitate the process of picking and materials storage. A kanban card-based supply system was also expanded to the bus assembly line, allowing more control over valuable materials.

This study has demonstrated how the implementation of lean techniques on a bus assembly line can lead to increased consistency of supply to the line and improved working conditions, both in the production and warehouse areas. Furthermore, it has set a new standard of the internal logistics processes and the inclusion of process recording in the working instructions.

This study aims to adapt and validate the need satisfaction and frustration scale (NSFS) for the Brazilian gig work context and investigate the distinctiveness of the constructs of basic needs satisfaction and frustration among Brazilian gig workers.

Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted on a sample of 351 Brazilian gig workers.

Results from EFA supported a three-factor structure, while results from CFA psychometrically supported a six-factor correlated model. The items that constitute the NSFS presented good discriminant validity (heterotrait-monotrait ratio) and internal consistency (Cronbach’s alpha and McDonald’s omega coefficients). Results regarding criterion validity partially support previous empirical evidence that considers needs satisfaction and frustration independent in relation to well-being and ill-being while reinforcing the need for further investigations. The Brazilian version of the NSFS is shown to be an instrument with robust psychometric qualities to assess workers’ perception of basic needs satisfaction and frustration in Brazilian gig work context.

This study broadens the scope of research on basic psychological needs by introducing a valid and reliable instrument to assess workers’ perceptions of needs satisfaction and frustration in the Brazilian gig work context, a population that has been neglected in self-determination theory research.

O presente estudo teve como objetivos (1) adaptar e validar a Need Satisfaction and Frustration Scale para o contexto brasileiro de gig work e (2) investigar a distinção dos construtos de satisfação e frustração das necessidades básicas entre os trabalhadores gig brasileiros.

A análise fatorial exploratória (AFE) e a análise fatorial confirmatória (AFC) foram realizadas em uma amostra de 351 trabalhadores gig brasileiros.

Os resultados da EFA apoiaram uma estrutura de três fatores, enquanto os resultados da AFC apoiaram psicometricamente um modelo correlacionado de seis fatores. Os itens que constituem a NSFS apresentaram boa validade discriminante (razão heterotraço-monotraço) e consistência interna (coeficientes alfa de Cronbach e ômega de McDonald). Os resultados relativos à validade de critério apoiam parcialmente as evidências empíricas anteriores que consideram a satisfação e frustração das necessidades independentes em relação ao bem-estar e mal-estar, reforçando a necessidade de mais investigações. A versão brasileira da Need Satisfaction and Frustration Scale mostra-se um instrumento com qualidades psicométricas robustas para avaliar a percepção dos trabalhadores quanto à satisfação e frustração das necessidades básicas no contexto brasileiro de trabalho gig.

Este estudo amplia o escopo da pesquisa sobre necessidades psicológicas básicas ao introduzir um instrumento válido e confiável para avaliar as percepções de satisfação e frustração das necessidades dos trabalhadores no contexto brasileiro de gig work, uma população que tem sido negligenciada nas pesquisas da teoria da autodeterminação.

The purpose of this paper is to analyse if the existence of equal opportunity legislative frameworks and affirmative action programs make any difference to the way senior managers perceive the role of top university managers in influencing women's position in their institutions. A comparative study was therefore undertaken between a country with traditions in implementing AA in universities – Australia – and another which has no tradition in this domain – Portugal.

A qualitative methodology was chosen to collect and analyse data. A total of 44 interviews with male and female university senior managers – 21 in Australia and 23 in Portugal – were conducted by the principal researcher in each country.

When describing the role of top managers, gender equality was not often mentioned, suggesting that it may not be a topic on the current institutional political agenda either in Australia or in Portugal. When specifically asked about gender, respondents considered that Rectors and VCs in the two countries took opposite positions with Australian VCs being more aware of their role in improving gender equality. The study therefore concluded that the existence of equal opportunities frameworks and AA policies may have an influence in increasing top managers’ awareness of their roles in improving women's representation in management teams.

The research was restricted to public universities. In Portugal the system is more diverse and comparing HE with private and polytechnic institutions could provide important insights about senior managers’ roles in relation to improving women's position in HE. More in‐depth qualitative studies are needed, to obtain top managers’ perceptions of the variables that impact on their views and attitudes to women in senior management.

This study provides new and innovative contributions to knowledge about the perceptions of senior managers of their top managers and their roles in eliminating gender discrimination and the influence of affirmative action in HE in these perceptions.

This paper contributes to the discussion on the advantages and disadvantages of using affirmative action programmes by analyzing a dimension which has not been explored – its impact on senior managers’ perceptions of their role in promoting gender equality in HEIs.

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.
