The number of people with special needs, including citizens and military personnel, has increased as a result of terrorist attacks and challenging conditions in Iraq and other countries. With almost 80% of the world’s amputees having below-the-knee amputations, Iraq has become a global leader in the population of amputees. Important components found in lower limb prostheses include the socket, pylon (shank), prosthetic foot and connections.

There are two types of prosthetic feet: articulated and nonarticulated. The solid ankle cushion heel foot is the nonarticulated foot that is most frequently used. The goal of this study is to use a composite filament to create a revolutionary prosthetic foot that will last longer, have better dorsiflexion and be more stable and comfortable for the user. The current study, in addition to pure polylactic acid (PLA) filament, 3D prints test items using a variety of composite filaments, such as PLA/wood, PLA/carbon fiber and PLA/marble, to accomplish this goal. The experimental step entails mechanical testing of the samples, which includes tensile testing and hardness evaluation, and material characterization by scanning electron microscopy-energy dispersive spectrometer analysis. The study also presents a novel design for the nonarticulated foot that was produced with SOLIDWORKS and put through ANSYS analysis. Three types of feet are produced using PLA, PLA/marble and carbon-covered PLA/marble materials. Furthermore, the manufactured prosthetic foot undergoes testing for dorsiflexion and fatigue.

The findings reveal that the newly designed prosthetic foot using carbon fiber-covered PLA/marble material surpasses the PLA and PLA/marble foot in terms of performance, cost-effectiveness and weight.

To the best of the author’s knowledge, this is the first study to use composite filaments not previously used, such as PLA/wood, PLA/carbon fiber and PLA/marble, to design and produce a new prosthetic foot with a longer lifespan, improved dorsiflexion, greater stability and enhanced comfort for the patient. Beside the experimental work, a numerical technique specifically the finite element method, is used to assess the mechanical behavior of the newly designed foot structure.

This study aims to investigate the gender diversity within innovation and entrepreneurship teams and the perceptions of gender imbalance in digital skills among team members in Kazakhstan, a Central Asian country belonging to the Global South.

Primary data were collected from ten leading firms in Kazakhstan's manufacturing, construction and oil and gas sectors, which have international connections or perspectives. The members of the research and development (R&D) departments of these firms completed an online, structured closed-question questionnaire anonymously. A total of 169 completed responses were analyzed using regression analysis, controlling for company size and sector, with gender as the independent variable.

The gender diversity within innovation teams is not as high as anticipated, even though there is a substantial representation of women in the scientific workforce across many firms. Similarly, there is a gender gap in entrepreneurship teams involved in business innovation, although it is slightly less pronounced. Female employees report a greater disparity compared to their male counterparts. Surprisingly, over 60% of both male and female respondents agree that women lack the same level of digital expertise and knowledge as men.

The findings of this research should be interpreted in light of the fact that they are based on a perception-based survey. Local firms exhibit skepticism toward external researchers due to privacy concerns, making their participation challenging. However, it is noteworthy that the survey targeted front-line workers in the innovation and entrepreneurship field, providing informed perspectives that strengthen the study's outcomes.

This study reveals that while women form a considerable proportion the scientific workforce, gender diversity in innovation and entrepreneurship teams is lacking in a Global South country. Gender imbalance in innovation and entrepreneurship is thus present in both developing and developed countries, highlighting the need for interventions to promote gender diversity at the firm level.

This study aimed to analyze top management commitment to business performance in the context of coffee processing firms in Guji Zone, Ethiopia.

The study was conducted on coffee processing firms in Guji Zone, Ethiopia, using a mixed approach with a descriptive and explanatory design. A systematic, simple random sampling technique was used to draw a sample. A total of 345 respondents were actively involved in the survey. Descriptive and inferential statistics were applied to analyze the data through SPSS-20.

The results indicate that members of top management in the sector were committed to promoting their business performance. The findings of the study also reveal that top management commitment has significant and positive effects on the overall business performance of coffee processing firms.

The study was limited to the coffee processing industry and generalization of the results to other sectors may be questionable. Similarly, the study was presented using primary data only. Thus, future researchers will be advised to strengthen their findings using the secondary data.

The study’s implications have contributed to theoretical, practical and managerial perspectives. The findings validate and refine existing theories, provide practical insights for coffee processing firms and offer guidance for managerial decision-making and leadership development.

Up to the time of the authors' literature review, no study with a similar topic on coffee processing firms in the Guji Zone was found and it is believed to be the first literature evidence for future researchers.
