This study aims to deal with both the development and mechanical investigations of unsaturated polyester matrix (UPR) composites containing recycled polyethylene terephthalate (PET) fibers as new fillers.

UPR/PET fibers composites have been developed as mats by incorporating 5, 8, 13 and 18 parts per hundred of rubber (phr) of 6-, 10- and 15-mm length PET fibers from the recycling of postconsumer bottles. The mechanical and physical properties of the composites were investigated as a function of fiber content and length. A significant increase in stress at break and in ultimate stress (sr) were observed for composites reinforced with 5 and 8 phr of 15-mm length PET fibers. The Izod impact strength of UPR/mat PET fiber composites as a function of fiber rate and length showed that the 5 and 8 phr composites for the 15-mm length PET fiber have the optimal mechanical properties 13.55 and 10.50 Kj/m², respectively. The morphological study showed that the strong adhesion resulting from the affinity of the PET fiber for the UPR matrix. The ductile fracture of materials reinforced with 5 and 8 phr is confirmed by the fiber deformation and fracture surface roughness.

This study concluded that the PET fiber enhances the properties of composites, a good correlation was observed between the results of the mechanical tests and the structural analysis revealing that for the lower concentrations, the PET fibers are well dispersed into the resin, but entanglements are evidenced when the fiber content increases.

It can be shown from scanning electron microscopy micrographs that the fabrication technique produced composites with good interfacial adhesion between PET fibers and UPR matrix.

Sustainability start-ups introduce business models that address current environmental and social challenges. However, to reach their mission, they need to integrate the intention of delivering such impact since their formulation. Business incubators show promise in supporting them in this process by enhancing their access to resources and knowledge during the early stage. For these reasons, this paper aims to investigate the transfer of knowledge in a support program, outlining what knowledge is transferred in the program and through which activities for encouraging the generation of sustainability start-ups’ impact.

The present paper is supported by a qualitative case study methodology based on primary data (interviews) and secondary data (internal and external documents) related to a French support program.

The study shows that the support program transfers explicit and tacit knowledge for encouraging the generation of sustainability impact, throughout three main phases: awareness, identification and assessment.

The limitation concerns the analysis of a French support program and the focus on sustainability start-ups. Future research lines will study other and more traditional business incubators to confirm and possibly enrich the results.

The study has managerial implications for incubator managers willing to support sustainable entrepreneurship and for sustainable entrepreneurs who want to find a support program and reach their impact.

The study shows that a sustainability orientation in business incubators can play a role in fostering sustainable development through the creation of new sustainability ventures.

This paper contributes to two different fields: sustainable entrepreneurship support and knowledge management in incubators.

This paper presents results from a participatory action research study with 46 LGBTQIA+ community leaders and 60 library workers who participated in four community forums at public libraries across the US. The forums identified barriers to LGBTQIA+ communities addressing their health questions and concerns and explored strategies for public libraries to tackle them.

Forums followed the World Café format to facilitate collaborative knowledge development and promote participant-led change. Data sources included collaborative notes taken by participants and observational researcher notes. Data analysis consisted of emic/etic qualitative coding.

Results revealed that barriers experienced by LGBTQIA+ communities are structurally and socially entrenched and require systematic changes. Public libraries must expand their strategies beyond collection development and one-off programming to meet these requirements. Suggested strategies include outreach and community engagement and mutual aid initiatives characterized by explicit advocacy for LGBTQIA+ communities and community organizing approaches.

Limitations include the sample's lack of racial diversity and the gap in the data collection period between forums due to COVID-19. Public libraries can readily adopt strategies overviewed in this paper for LGBTQIA+ health promotion.

This research used a unique methodology within the Library and Information Science (LIS) field to engage LGBTQIA+ community leaders and library workers in conversations about how public libraries can contribute to LGBTQIA+ health promotion. Prior research has often captured these perspectives separately. Uniting the groups facilitated understanding of each other's strengths and challenges, identifying strategies more relevant than asking either group alone.

The purpose of this study is to know the influence of palm oil fuel ash and metakaolin on the strength of concrete and crack resistance of reinforced concrete beam. An ordinary portland cement has been used in the concretes production where it is an important material to be considered due to its nature that reacts with every substance present. During the cement production, a significant amount of carbon dioxide is emitted from the clinker in rotary kiln and lot of energy is required in the production processes. Such an event can be prevented by replacing the part of cement with metakaolin (MK) and palm oil fuel ash (POFA). Aside from being a cementitious alternative, the materials can also contribute to a greener environment and more sustainable building, as POFA is available in Malaysia and may be used to substitute cement and minimize pollution.

This study assesses the effect of MK and POFA on the concrete in terms of compressive strength and cracks pattern of the reinforced concrete beam based on the relevant previous studies.

From this study, the compressive strength of concrete containing MK and POFA was higher than the control mix with the percentage of improvement in the range of 0.8%–78.2% for MK and 0.5%–14%, respectively. The optimum content of MK and POFA is between the range of 10% and 15% and 10% and 20%, respectively, to achieve high strength of concrete. Other than that, the inclusion of MK to the concrete mix improves the strength of reinforced concrete beams and reduces cracks on the surface of reinforced concrete beams, whereas the inclusion of POFA to the concrete mix increases the cracks on reinforced concrete beams. The cracks appeared within the flexure zone of every beam containing the MK and POFA.

It was found that the fineness of MK and POFA has a significant influence on the mechanical properties of concrete.

Model-based systems engineering (MBSE) is an important approach for the transforming process from “document-centered” to “model centered” systems engineering mode in equipment development, which can effectively shorten the equipment development cycle and improve product design quality. This paper aims to understand if MBSE enables to support manufacturing and equipment development.

The paper opted a bibliometric analysis of MBSE in domain of advanced manufacturing from different perspectives such as publication volume, research team, sources and keyword co-occurrence.

Firstly, the application of MBSE in advanced manufacturing can be roughly divided into three stages. And MBSE has been widely implemented globally and has gradually formed several noteworthy teams. Secondly, this article has identified some high-quality sources, with a large number of publications and citations, the most influential publications focus on the practice or guidance of digital twins and intelligent manufacturing. Thirdly, research can be divided into six categories, including systems engineering, digitalization, intelligent manufacturing, product design, model and architecture and MBSE applications.

Because of the chosen research approach, the visualized network tends to lose certain information such as a few keywords may be inaccurately categorized.

This paper comprehensively study the research status of MBSE in advanced manufacturing and forecasts future research trends, emphasizing the combination of intelligent manufacturing and digitization.

This paper fulfills an identified need to understand the current application status and future development trends of MBSE.

This study, a systematic literature review, aims to review the state-of-the-art literature on choice overload from 2000 to 2023.

The paper reviews 53 research articles published in peer-reviewed journals, using thematic and descriptive analyses. The literature was selected using the PRISMA framework.

Recent research in consumer behaviour has found that too many choices can be detrimental to decision-making. This paper reviews the development of choice overload literature, methodologies used by researchers to study choice overload, small and large choice sets, antecedents, moderators and outcomes of choice overload and the contexts in which choice overload exists.

Limited literature coverage because of the strict adherence to inclusion/exclusion criteria. The theory challenges the conventional choice models in psychology and economics according to which expanding a choice set cannot make decision-making worse and violates the regularity axiom, a cornerstone of classical choice theory. This review also identifies avenues for further research in the field.

A significant decrease in satisfaction or motivation because of too many choices would require marketers and public policymakers to rethink their practice of providing ever-increasing assortments to choose from because they could possibly boost their success by offering less.

This systematic review makes distinctive contributions by classifying the existing studies based on evidence “for” and “against” the existence of choice overload. The review also combines cross-context insights on assortment sizes, moderators and methodological commonalities and gaps to understand the multi-faceted nature and contextual nuances of choice overload.

The aim of this study is to systematise the entrepreneurial coaching (EC) literature by understanding how the phenomenon has been investigated along four dimensions inspired by Gartner’s (1985) conceptualisation of entrepreneurship: entrepreneurial process, context, target and outcomes. In so doing, this study will provide a frame of its multifunctional role and identify relevant gaps and suggestions for future research.

We conducted a systematic literature review to collect existing works on EC. We analysed 85 selected papers with a qualitative content analysis that allowed us to highlight relevant research themes for the entrepreneurial process, context, outcomes and target.

Our results demonstrate that EC has a multifunctional role in entrepreneurship that can be summarised in five different typologies, depending on the stage of the entrepreneurial process in which it is applied, the context, the target and the outcomes.

As one of the first attempts to systematise studies on EC, this work extends previous conceptualisation of EC by detailing different typologies of this intervention, thereby contributing to reduced fragmentation and conceptual ambiguity.

The purpose of this paper is to understand how individuals seek to reduce the occurrence of unethical requests at work and the effects of such strategies.

The authors built a grounded theory through semi-structured interviews with 65 individuals who worked for companies involved in the Brazilian corruption scandal called Operation Car Wash.

The interviewees reported that they use two central strategies to avoid unethical requests: explicit moral communication (directly stating that they are not willing to adhere to an unethical request) and implicit communication (expressing such a refusal through moral symbols). Both strategies signal the morality of the communicator and lead the possible proponent of an unethical request to perceive a greater probability of being reported and, thus, avoid making such an unethical request. However, while explicit moral communication affects the perceived morality of the individual who would possibly make an unethical request, implicit (symbolic) moral communication does not. As a consequence, the risks of retaliation for making a moral communication are greater in the case of explicit moral communication, entailing that implicit moral communication is more effective and safer for the individual who wants to avoid unethical requests.

This paper broadens the literature on business ethics and moral psychology by shifting its focus from what organizations and leaders can do to prevent unethical behavior to what leaders can actively do to protect themselves from unethical requests.
