HyFlex course design is an effective instructional course design that combines active and transformative learning techniques. HyFlex course design encourages active learning by focusing on interactive activities, discussions, and collaboration. It also allows learners to collaborate effectively and flexibly as a community, providing peer support and opportunities for authentic dialogue and learning experiences. HyFlex course design provides the opportunity for transformative learning through its ability to offer personalized educational experiences to individuals. It facilitates greater customization of the learning experience, allowing individual learners to access tailored educational modules, offer personalized educational experiences to individuals, and effectively develop and build independent and critical thinking skills. This conceptual review, supported by implications from HyFlex literature and triangulated with experts' views undertaking a Delphi study, facilitates understanding the current state of research in HyFlex course design and future application strategies. Existing research has identified HyFlex courses as a promising means of engaging students in active learning. Allowing students to learn through flexibly predesigned mixed online and in-person experiences enables higher levels of student autonomy and supports students in taking more ownership of their learning. This approach can facilitate an understanding of how HyFlex courses can improve active learning practices in higher education. The review study findings identify the reported alignment issues and challenges, suggest four strategies and actions for policymakers and stakeholders, and provide a suggested research agenda for bridging identified research gaps.

Future research can provide evidence of the benefits of HyFlex course design and how flexible course design can address the challenges of traditional face-to-face courses, such as reduced student engagement, lack of student-centered approaches, and limited support for different learning styles. Further research can focus on strategies that can be used to promote active learning in HyFlex courses. Moreover, research can investigate how this kind of course design can equip educators with the skills and knowledge needed to design and implement effective and meaningful active learning experiences. Finally, research can assess the potential impact of HyFlex course design on student outcomes, including performance, satisfaction, and engagement.

This paper aims to explore the ambiguity and limitations of measuring firm-level multinationality (FLM) using theoretical and empirical comparisons of existing methods. The paper puts forward a list of five key aspects that collectively serve as a tool for researchers to select the most appropriate method for future research and as a basis for the future development of methods.

Firstly, the author reviews existing methods of measuring FLM and consolidates findings into five key aspects. Secondly, the author uses the aspects to compare existing methods theoretically, and subsequently, the author groups them into three distinct streams. Thirdly, the author compares existing methods across a sample of the 35 largest European MNEs by sales in 2020 to identify and demonstrate the ambiguity and limitations of these methods.

The author identifies the five key aspects of measuring FLM: framework, aggregation, segmentation, metrics and indicators. Using empirical comparison, the author empirically confirms the limitations highlighted in the literature and shows the differences and inconsistencies among methods, which cause confusion rather than clarity in the extant literature. Additionally, the author emphasises that three distinct streams further drive the debate on the regional/global nature and present further limitations of methods not mentioned in the literature to date.

This paper provides the most comprehensive review of the existing literature on FLM, resulting in five novel aspects of measuring FLM. The analysis of a sample of 35 European firms demonstrates and identifies the ambiguity and limitations of FLM-measuring methods.

Two-level support with Level 1 consisting of a set of beams and Level 2 consisting of a tree-like structure is an efficient support structure for extrusion-based additive manufacturing (EBAM). However, the literature for finding a slim two-level support is rare. The purpose of this paper is to design a lightweight two-level support structure for EBAM.

To efficiently solve the problem, the lightweight design problem is split into two subproblems: finding a slim Level 1 support and a slim Level 2 support. To solve these two subproblems, this paper develops three efficient metaheuristic algorithms, i.e. genetic algorithm (GA), genetic programming (GP) and particle swarm optimization (PSO). They are problem-independent and are powerful in global search. For the first subproblem, considering the path direction is a critical factor influencing the layout of Level 1 support, this paper solves it by splitting the overhang region into a set of subregions, and determining the path direction (vertical or horizontal) in each subregion using GA. For the second subproblem, a hybrid of two metaheuristic algorithms is proposed: the GP manipulates the topologies of the tree support, while the PSO optimizes the position of nodes and the diameter of tree branches. In particular, each chromosome is encoded as a single virtual tree for GP to make it easy to manipulate Crossover and Mutation. Furthermore, a local strategy of geometric search is designed to help the hybrid algorithm reach a better result.

Simulation results show that the proposed method is preferred over the existing method: it saves the materials of the two-level support up to 26.34%, the materials of the Level 1 support up to 6.62% and the materials of the Level 2 support up to 37.93%. The proposed local strategy of geometric search can further improve the hybrid algorithm, saving up to 17.88% of Level 2 support materials.

The proposed approach for sliming Level 1 support requires the overhanging region to be a rectilinear polygon and the path direction in a subregion to be vertical or horizontal. This limitation limits the further material savings of the Level 1 support. In future research, the proposed approach can be extended to handle an arbitrary overhang region, each with several choices of path directions.

The details of how to integrate the proposed algorithm into the open-source program CuraEngine 4.13.0 is presented. This is helpful for the designers and manufacturers to practice on their own 3D printers.

The path planning of the overhang is a critical factor influencing the distribution of supporting points and will thus influence the shape of the support structure. Different from existing approaches that use single path directions, the proposed method optimizes the volume of the support structure by planning hybrid paths of the overhangs.

France is the third country in Europe after Italy and Spain for the number of employee-owned firms, with some 2,600 worker cooperatives (SCOPs). The authors propose a comprehensive review of SCOPs and any barriers to their expansion.

The authors analyse relevant legislation; review the rich empirical economic literature on SCOPs; and offer new descriptive empirical evidence comparing SCOPs and other French firms.

SCOPs benefit from a consistent legal framework and a well-structured and supportive cooperative movement. Cooperative laws allow attracting external capital, provide barriers against degeneration and encourage profit allocations that favour investment and labour. SCOPs are distributed across a wide range of industries; are larger than conventional firms, as capital intensive, more productive and survive better. Despite this good performance their number remains modest, perhaps because of information barriers.

An examination of the Italian and Spanish experiences and the relationship between SCOPs and the French labour movement might contribute to explaining the modest number of SCOPs.

The first comprehensive review of French worker cooperatives in four decades and the first with extensive comparative data on SCOPs and conventional French firms. With some of the best data on worker cooperatives in the world, findings have international relevance.

Vehicle allocation problems (VAPs), which are frequently confronted in many transportation activities, primarily including but not limited to full truckload freight transportation operations, induce a significant economic impact. Despite the increasing academic attention to the field, literature still fails to match the needs of and opportunities in the growing industrial practices. In particular, the literature can grow upon the ideas on sustainability, Industry 4.0 and collaboration, which shape future practices not only in logistics but also in many other industries. This review has the potential to enhance and accelerate the development of relevant literature that matches the challenges confronted in industrial problems. Furthermore, this review can help to explore the existing methods, algorithms and techniques employed to address this problem, reveal directions and generate inspiration for potential improvements.

This study provides a literature review on VAPs, focusing on quantitative models that incorporate any of the following emerging logistics trends: sustainability, Industry 4.0 and logistics collaboration.

In the literature, sustainability interactions have been limited to environmental externalities (mostly reducing operational-level emissions) and economic considerations; however, emissions generated throughout the supply chain, other environmental externalities such as waste and product deterioration, or the level of stakeholder engagement, etc., are to be monitored in order to achieve overall climate-neutral services to the society. Moreover, even though there are many types of collaboration (such as co-opetition and vertical collaboration) and Industry 4.0 opportunities (such as sharing information and comanaging distribution operations) that could improve vehicle allocation operations, these topics have not yet received sufficient attention from researchers.

The scientific contribution of this study is twofold: (1) This study analyses decision models of each reviewed article in terms of decision variable, constraint and assumption sets, objectives, modeling and solving approaches, the contribution of the article and the way that any of sustainability, Industry 4.0 and collaboration aspects are incorporated into the model. (2) The authors provide a discussion on the gaps in the related literature, particularly focusing on practical opportunities and serving climate-neutrality targets, carried out under four main streams: logistics collaboration possibilities, supply chain risks, smart solutions and various other potential practices. As a result, the review provides several gaps in the literature and/or potential research ideas that can improve the literature and may provide positive industrial impacts, particularly on how logistics collaboration may be further engaged, which supply chain risks are to be incorporated into decision models, and how smart solutions can be employed to cope with uncertainty and improve the effectiveness and efficiency of operations.

Material extrusion (MEX) 3D printers suffer from an intrinsic limitation of small size of the prints due to its restricted bed dimension. On the other hand, friction stir spot welding (FSSW) is gaining wide interest from automobile, airplane, off-road equipment manufacturers and even consumer electronics. This paper aims to explore the possibility of FSSW on Acrylonitrile Butadiene Styrene/Polylactic acid 3D-printed components to overcome the bed size limitation of MEX 3D printers.

Four different tool geometries (tapered cylindrical pin with/without concavity, pinless with/without concavity) were used to produce the joints. Three critical process parameters related to FSSW (tool rotational speed, plunge depth and dwell time) and two related to 3D printing (material combination and infill percentages) were investigated and optimized using the Taguchi L27 design of experiments. The influence of each welding parameter on the shear strength was evaluated by analysis of variance.

Results revealed that the infill percentage, a 3D printing parameter, had the maximum effect on the joint strength. The joints displayed pull nugget, cross nugget and substrate failure morphologies. The outcome resulted in the joint efficiency reaching up to 100.3%, better than that obtained by other competitive processes for 3D-printed thermoplastics. The results, when applied to weld a UAV wing, showed good strength and integrity. Further, grafting the joints with nylon micro-particles was also investigated, resulting in a detrimental effect on the strength.

To the best of the authors’ knowledge, this is the first study to demonstrate that the welding of dissimilar 3D-printed thermoplastics with/without microparticles is possible by FSSW, whilst the process parameters have a considerable consequence on the bond strength.

Although women have advanced in the economic sphere, the gender pay gap (GPG) remains a persisting problem for gender equality. Using Acker's theory of gendered organisations, this study strives to gain a better understanding from a macro and micro approach, how family and work-related policies, especially family-friendly measures (FFMs), and their uptake, contribute and maintain the GPG in Malta and specifically within the Financial and Insurance sector.

Two research instruments were used. National policy documents were analysed through the gender lens, followed by structured interviews with HR managerial participants within this sector.

Findings suggest that at a macro level, family and work-related policies could be divided into two broad categories: A set of family-friendly policies that contribute to the GPG because of their gendered nature, or because the uptake is mostly taken by women. These include make-work pay policies, which initially appear to be gender neutral, but which attracted lower educated inactive women to the Maltese labour market at low pay, contributing to an increase in the GPG. Second, a set of policies that take on a gender-neutral approach and help reduce the GPG. These include policies like the free childcare and after school care scheme that allow mothers to have a better adherence to the labour market. At the micro level within organisations, pay discrepancies between women and men were largely negated and awareness about the issue was low. Here, “ideal worker” values based on masculine norms seemed to lead to covert biases towards mothers who shoulder heavier care responsibilities in the families and make a bigger use of FFMs. Because men are better able to conform to these gendered values and norms, the GPG persists through vertical segregation and glass ceilings, among others.

Since not all the companies in the Eurostat NACE code list participated in this research, results could not be generalised but were indicative to future large-scale studies..

At the macro and policy level, some FFMs take on a clear gendered approach. For example, the disparity in length between maternity (18 weeks) and paternity leave (1 day) reinforces gender roles and stereotypes, which contribute to the GPG in the long run. While some FFMs like parental leave, career breaks, urgent family leave, telework, flexible and reduced hours seem to take on a more gender-neutral approach, the uptake of FFMs (except childcare) seems to generate discriminatory behaviour that may affect the GPG. When considering the make-work pay policies such as the “in-work benefit” and the “tapering of benefits”, this study showed that these policies attracted lower educated and low-skilled women into the labour market, which in turn may have further contributed to the increasing GPGs. On the other hand, the childcare and after school policies relieve working mothers from caregiving duties, minimising career interruptions, discriminatory behaviour and overall GPGs.

This study confirmed that organisations within the Financial and Insurance sector are gendered and give value to full-time commitment and long working hours, especially in managerial roles. Managerial positions remain associated with men because mothers tend to make more use of FFMs such as parental leave, reduced, flexible hours and teleworking. Mothers are indirectly penalised for doing so, because in gendered organisations, the uptake of FFMs conflict with the demands of work and ideal worker values (Acker, 1990). This maintains the vertical segregation and widens the GPG within the Financial and Insurance sector.

By using the gender lens and taking a wider and more holistic approach from the macro and micro level, this study highlights how interlinking factors lead to and sustain the GPG in the Financial and Insurance sector in Malta.

This paper aims to investigate whether Kazakh small- and medium-sized enterprises (SMEs) that claim to compete with the informal sector are more likely to invest in innovation than their competitors who do not perceive such pressure.

Logistic regression and classification trees are performed on the Business Environment and Enterprise Performance Survey (2018–2020) to examine whether the degree of informal competition correlates with a firm's propensity to innovate.

The findings show that informal sector competition is a critical factor that shapes the organizational behaviour of Kazakh SMEs. There is a stimulating positive effect of informal competition on both product and process innovation, depending on its perceived intensity.

This study challenges conventional thinking that still views informal sector competition as a barrier to innovation and entrepreneurship by assessing whether innovation is compatible with informal entrepreneurial practice.

Currently, owing to the influence of rapid globalisation, the issue of international and cross-cultural implementation of cross-cultural relationships is being widely discussed. This is also related to the readiness of graduates for international cooperation. The objective of this qualitative study is to identify and compare the requirements of company representatives from the Czech Republic – the Vysocina Region and Austria (Region Upper Austria) regarding the readiness of graduates to entering the workforce and the intercultural differences between the relevant regions.

A total of 20 Czech and Austrian companies from the relevant regions participated in the research. The results were obtained through in-depth guided interviews and a comparative method.

The qualitative study has theoretical implications in the context of new findings in the field of research. It contributes to the knowledge relating to the preparation of graduates for entering the workforce, and in the context of intercultural development, it extends this knowledge with the identified weaknesses of the mentioned preparation at the level of Czech or Austrian education.

The most effective and probable approach to enhance the development of cross-cultural competences in particular appears to be the integration of new techniques and content of education in the form of new subjects in cooperation with academics and practitioners from the particular country. Collaboration with these experts can build students' knowledge and skills from an intercultural environment to the highest degree possible.
