Shape memory polymers (SMPs) are classified as smart materials owing to their inherent stimulus-induced response. SMPs are capable of recovering partially or totally to its original shape after a high degree of deformation by external stimulus. The most used stimuli are thermal, light, magnetic field and electricity. This research aims to characterize the toughness property of thermo-responsive SMP specimens fabricated by the material extrusion (ME) process and to investigate the impact of ME parameters on specimen maximum load and load-displacement curves. Moreover, to investigate the recovery efficiency based on the initial and post toughness generated by the compact tension test.

A design of experiments with three parameters (temperature, velocity and layer height) defined the ME settings to fabricate the specimens. The ME raster orientation factor was also evaluated separately. In addition, one more specimen group assisted by a clamp during the recovery process was compared with a specimen control group. After fabrication, specimens were submitted to a thermo-mechanical cycle that encompasses a compact tension test and a thermo-recovery process. Comparison studies of load-displacement, toughness and recovery efficiency of the specimens were carried out to determine the optimized fabrication parameters.

It was found that ME parameters and raster orientation impacted the test results. Samples with the clamp support during recovery returned a higher toughness than samples without support. Finally, results showed that the shape memory effect can contribute with up to 43 per cent recovery efficiency in a first recovery and up to 23 per cent in a second recovery of damaged specimens.

Shape memory polymer (SMP) is capable of recovering its original shape from a high degree of deformation by applying an external stimulus such as thermal energy. This research presents an integration of two commercial SMP materials (DiAPLEX and Tecoflex) and a material extrusion (ME) printer to fabricate SMP parts and specimens. The material properties such as Young’s modulus of the specimens was examined as a process output. Furthermore, stress-strain curve, strain recovery, instant shape-fixity ratio, long-term shape-fixity ratio and recovery ratio of SMP specimens during a thermo-mechanical cycle were investigated.

The ME fabrication settings for the SMP specimens were defined by implementing a design of experiments with temperature, velocity and layer height as process variables.

It was found, according to main effect and iteration plots, that fabrication parameters have an impact on Young’s modulus and exist minimum iteration among variables. In addition, Young’s modulus variation of DiAPLEX and Tecoflex specimens was mostly caused by velocity and layer height parameters, respectively. Moreover, results showed that SMP specimens were able to recover high levels of deformation.

This paper is a reference for process control and for rheological properties of SMP parts produced by ME fabrication process.

The purpose of this paper is to explore the causal links between public and private university environments and the entrepreneurial intention (EI) of students.

The impact of different university environments on the students’ EI was checked using a model adapted from Krueger et al. (2000). The study comprised a sample of students enrolled in business administration from three public and three private universities at first semester (freshmen) and at the last two semesters (senior) in Brazil. The model was measured through various questions and later assessed by principal component analysis to build constructs. Via t-test and path analysis the EI and the antecedents were subjected to a comparative analysis to test the equality of the models across the four categories emerged.

The two main types of Brazilian university environments (public and private) do not present significant differences in the way they influence EI and its antecedents. Both the tests of means and the tests of measurement of the structural relations between constructs confirm this finding with only a few exceptions. The result of this study is opposed to other studies carried out in Brazil, by showing that the public university environment is not worse for the entrepreneurship than the private. The environmental effects are mostly equal and they as a whole are not conducive to the development of EI.

The study comprises business students only, and enrolled on regular universities. It is worth highlighting that evidence was brought to the debate for a group of universities in Brazil. Replicating the study with students from other areas and other universities, as well as students in Master’s and Doctorate programs could enrich the analyses.

This study provides insight into entrepreneurship education, as to which the university environment is conducive to the entrepreneurship. It brings insights for the development of entrepreneurial universities.

This study contributes to understanding the differences between the public and private universities environment regarding students’ EI.

This study aims to investigate the role of board gender diversity in explaining the effects of board members’ political connections on banking performance in the Eurozone.

This paper analyses panel data on 83 banks supervised by the European Central Bank (ECB) for the period 2013–2017, using a generalized moment method-type estimation methodology.

Results suggest that when gender diversity is high, there is a U-shaped nonlinear relationship between political connections and banking performance. Empirical evidence also indicates that differentiating characteristics of women, such as greater ethical concern and risk aversion, help mitigate the negative effects of political connections on banking performance, safeguarding the institutions’ interests from the adverse effects of personal agendas. In addition, these results also suggest that a minimum of 14% of gender diversity can contribute to greater social justice and beneficial structural change.

The period studied may not yet fully reflect the impact of the assessment of the board members’ suitability.

The paper contributes to the growing literature on political connections and gender diversity, providing greater insight into their role as determinants of banking performance. The study also suggests the benefits and possible limitations of the regulator’s two impositions – gender diversity quotas and members’ repute (members’ political connections).

The effect of gender diversity on the impact of board members’ political connections on banking performance has not been studied, as these relationships have not been analysed separately for banks directly supervised by the ECB.

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.

This paper aims to understand how mental time traveling impacts consumption by triggering nostalgia. The effects of nostalgic behavior are explored further in regards of its impact on dears and nears.

This study is based on qualitative information from in-depth interviews. In total, 30 parents with children form Chihuahua, Mexico, answer to a semi-structured interview. Participants presented nostalgic orientation.

Nostalgic individual move back and forward in time through memory retrieval. Retrieval's quality is related to social impact during memory creation and retrieval process. Nostalgia is not only a cognitive process, but it manifests on behaviors that affects people around the nostalgic individuals. In the context of parent–child relationship, sharing nostalgia is useful for creating new bond across participants.

Contributions toward theory of memory, nostalgia and social learning were made. Result suggests social implications on nostalgic behavior because social interaction is important for quality of memory retrieval. Behavioral implications are discussed in the context of parent–child relationship and the use of nostalgia to develop new and stronger bonds. Companies should develop strategies that privilege social moments around brands to increase memory retrieval quality and nostalgia.

Companies should develop strategies that create social moments around brands to increase memory retrieval quality and nostalgia. Additionally, using social moments on communications could trigger nostalgia and detonates consumption behavior.

The research builds on previous studies about nostalgia. However, this research focusses on mental time travel along nostalgic memories that individuals perform every day to take decisions that affects them and their loved ones. The value of nostalgia on building relationships through consumption is analyzed. The results were obtained from the Mexican context that has not been explored before on nostalgia research.

The purpose of this study is to evaluate the effect of Hibiscus sabdariffa ethanolic extract (HsE) on protein levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6, adiponectin and leptin in adipose tissue, as well as on the lipid and glycemic profiles of high-fat/sugar diet-induced obese (DIO) rats.

Obesity was induced in male Wistar rats through a high-fat/sugar diet provided for eight weeks. Control rats received a standard diet. The high-fat/sugar DIO animals were subsequently randomized into DIO (n = 8) and DIO treated with HsE (DIO + HsE, n = 8, 150 mg/kg/day) by gavage, for additional eight weeks. Oral glucose tolerance test was performed, and blood samples and epididymal adipose tissue were collected for biochemical analysis and adipokine protein level evaluation, respectively.

Compared to the DIO rats, HsE treatment decreased weight gain (50.6%) and mesenteric fat (42%), indicated as diminished visceral fat (22.5%). HsE did not affect the lipid profile and TNF-α levels in adipose tissue; however, it effectively prevented a 13% increase in fasting glucose levels and improved glucose tolerance. Compared with the C group, HsE normalized the adiponectin levels and leptin/adiponectin ratio and decreased the IL-6 (55%) and leptin (18.6%) levels in adipose tissue of obese rats.

HsE improves adipokine protein levels in high-fat/sugar DIO rats, demonstrating the clinical efficacy of HsE in the treatment of obesity and obesity-related diseases.

This paper aims to assess the effectiveness of different segmentation schemes as the basis of marketing strategy, with particular respect to supply‐chain decisions, and to propose a new procedure capable of combining benefits sought and features available.

In a study of buyers and consumers of beef in Brazil, segments based on three approaches were derived by hierarchical cluster analysis, fine‐tuned by K‐means cluster analysis. The outcome was evaluated for the viability and actionability of the preferred procedure, both objectively and through interviews with managers in the beef‐supply business.

The results revealed that a segmentation scheme combining benefits sought and features available yields more homogeneous and actionable segments, and has real promise as an input to the formulation and implementation of supply‐chain strategy.

This promising innovation in market segmentation requires further study, and testing in the marketplace.

The proposed system is a usable aid to decision making.

The paper proposes an original approach to market segmentation.

This paper aims to provide an assessment of tourism promotion in tourist destinations and airports (TPTDs) and to organize and classify the literature on tourism promotion, with the aim of staging the importance of this topic and encouraging future research in the projection of tourism and marketing sectors.

The paper uses the Social Sciences Citation Index (SSCI) database to analyze the bibliometric in TPTDs topic from 2000 to 2021. Additionally, the paper also uses the visualization of similarities (VOS) viewer software to map graphically the bibliographic material. The graphical analysis uses bibliographic coupling, co-citation, citation and co-occurrence of keywords.

This study provides an amended new definition of tourism promotion, which is the efficient management of a destination’s resources and strategic plans by destination marketing organizations (DMOs) to adapt the tourism supply to market trends and will empower tourists to visit such destinations. Furthermore, results also show a new paradigm applied to TPTDs topic and classified in five first-order research streams. Digital and mobile marketing, infrastructure, branding, quality, accessibility and information factors about a specific destination which are mostly demanded by tourists are considered as an important means of promotion for the tourism industry.

The contribution of this study is important to identify new challenges and opportunities for researchers, DMOs, airport and airlines operators and stakeholders, as disentangling existing contradictions and applying new theoretical framework to make better future decisions by researchers and organizations to provide higher quality to new research in the context of the TPTDs.

The purpose of this study is to understand in what way the business strategy of a firm operating on a global scale is linked to its alliance portfolio,from the product-market matrix of Ansoff (1957) and the resources-partners matrix of Yasuda and Iijima (2005).

To meet this objective,the case study method was adopted,with data being obtained from interviews and documentary analysis of the selected firm/case: Borgstena Textile (BT).

Based on a content analysis approach,it was possible to observe an alliance portfolio with advantages for BT and include those partnerships in the four quadrants referring to the nature of resources and partners defined by Yasuda and Iijima. In terms of growth strategy,BT simultaneously defined the typology of product-market strategies proposed by Ansoff,i.e. BT tries to use strategic alliances to execute specific business strategies.

This research seeks to make a practical contribution,identifying the main association between the alliance portfolio and several specific firm strategies. This may allow better understanding of the composition of the alliance portfolio and,in this way,improve strategic management. This means that alliances should be managed as a whole and not in a dyadic way.

This study is innovative because it seeks to make a contribution to the literature,from a theoretical perspective,by developing two matrixes by Ansoff (1957) and Yasuda and Iijima (2005). These frameworks allow us to analyze the relationship between alliance portfolio and business strategy.
