    DATA AVAILABILITY : Data will be made available on request.The emergence of the Fourth Industrial Revolution (4IR) paradigm, whilst posing challenges, also presents significant opportunities to bolster research capabilities and pioneer breakthrough innovations that can stimulate economic growth across various sectors. However, the realisation of these benefits relies heavily on the ability of countries and their constituents to innovate effectively in this new landscape. The purpose of this study is to explore how innovation mechanisms can be employed to foster stronger innovation capabilities within a university ecosystem, particularly in the African context. To do so a case study methodology is used, where cross-sectional data gathered over six months is assessed using the Diffusion of Innovation (DOI) as a theoretical lens. The findings reveal that such innovation mechanisms, like a makerspace within a university ecosystem, provide critical support for design phase innovation and collaboration. We illustrate this by employing a conceptual framework that explains the process by which innovations evolve from ideas into valuable outcomes.https://www.elsevier.com/locate/techforehj2023InformaticsSDG-08:Decent work and economic growt

However, limited research has been conducted on exploring software development approaches concerning practitioners’ discussions on Q &A forums. Objective: We conducted an empirical study to analyze developers’ discussions on Q &A forums to gain insights into software development approaches in practice. Method: We analyzed 13,903 developers’ posts across Stack Overflow (SO), Software Engineering Stack Exchange (SESE), and Project Management Stack Exchange (PMSE) forums. A mixed method approach, consisting of the topic modeling technique (i.e., Latent Dirichlet Allocation (LDA)) and qualitative analysis, is used to identify frequently discussed topics of software development approaches, trends (popular, difficult topics), and the challenges faced by practitioners in adopting different software development approaches. Findings: We identified 15 frequently mentioned software development approaches topics on Q &A sites and observed an increase in trends for the top-3 most difficult topics requiring more attention. Finally, our study identified 49 challenges faced by practitioners while deploying various software development approaches, and we subsequently created a thematic map to represent these findings. Conclusions: The study findings serve as a useful resource for practitioners to overcome challenges, stay informed about current trends, and ultimately improve the quality of software products they develop.Peer reviewe

    Interrelationships between Circular Economy and Industry 4.0: A Research Agenda for Sustainable Supply Chains

    The purpose of this article is to propose a novel classification of the interrelationships between I4.0 technologies and CE principles that highlights the most conclusive findings and extant gaps in the relevant research. A Systematic Literature Review has been developed to locate, select and evaluate relevant contributions made to CE interrelationships with I4.0 technologies. Studies have been analysed and classified according to the specific I4.0 technology and CE principle addressed (10Rs). The articles have been clustered into three main groups: (i) useful application of materials; (ii) extending the lifespan of products and their parts, and (iii) smarter product use and manufacture. A mind map of the investigated articles has been used to establish the interrelationships between individual technologies and each CE principle at the supply chain level. Based on this classification, a focus group interview (FGI) was held with experts to dig deeper into the interrelationships between I4.0 technologies and CE principles. The FGI results have identified how each as yet unexplored I4.0 technology could be linked to each CE principle. A Fuzzy Delphi (FD) study was also applied to identify the most relevant I4.0 technologies for improving CE principles and closing gaps in the literature regarding the 10R CE principles. In addition, guidelines have been established to assist with practical applications and generate a research agenda on the interrelationships between I4.0 technologies and CE principles at the supply chain level. Implications for theory include the extension of view from the research gaps between I4.0 technologies and the 10Rs identified in the literature; also, an FGI and FD were performed based on the detected research gaps to identify future lines of research for academics and offer useful guidance to directors and managers on I4.0 technology interrelationships for improving at least one of the 10R CE principles. The contribution to practice aims to enable managers to easily identify which technology from the I4.0 domain should be used to advance any given CE principle. Lastly, we provide useful guidance on the application of as yet-unused technologies to improve CE principles

    El presente trabajo de investigación tiene como título: “Propuesta de un sistema mecanizado de izaje para mejorar la productividad del ciclo de extracción del pique 110 de la unidad minera La Verdosa”. La necesidad de la mina de obtener mejores resultados en el ciclo de extracción del pique 110, labor que se inició para profundizar y explorar la continuidad de la veta, llevo a que se busquen soluciones a raíz de la baja productividad en el subnivel 110, por eso se realizó la propuesta de la implementación de un sistema mecanizado de izaje para el pique 110. Por otro lado, en el subnivel 110, ubicado a 9.46 metros del nivel principal, es necesario la presencia de hasta 04 trabajadores para realizar los trabajos de perforación & voladura, limpieza del material (desmonte / mineral) y realizar la extracción de forma convencional ejerciendo fuerza del trabajador. Es por esto, que se estableció como objetivo principal proponer un sistema mecanizado de izaje para mejorar la productividad del ciclo de extracción del pique 110. El presente proyecto de investigación tiene como finalidad proponer mejoras en el ciclo de extracción de material en la zona de estudio. Para validar la propuesta se definió como zonas estudio zonas de estudio, el Pique 110 y el Subnivel 110, donde se realizaron estudio de tiempos detallados, además de la toma de datos del sistema de izaje mecanizado en operación. Se realizaron mediciones de tiempos de extracción de material en el pique 110 de la unidad minera, para tomar dicha información. Para tomar una decisión es necesario procesar la información y se realicen análisis estadísticos; con los cuales, se obtuvo que el costo operativo para extraer una tonelada métrica húmeda del SN 110 se redujo en 42.9% con respecto al sistema convencional, esta mejora se basa en la reducción de la cantidad de mano de obra empleada y las horas extras que se empleaba para culminar los trabajos. Por otro lado, respecto al tiempo el sistema de izaje es 7.02% más rápido para culminar un ciclo de izaje. Sin embargo, debido a la capacidad del skip del sistema mecanizado solo requiere de 09 ciclos en promedio para culminar con la extracción de un disparo del frente.The present research work is entitled: "Proposal of a mechanization model of the hoisting system to improve the productivity of the extraction cycle of the hoist 110 of the La Verdosa mining unit". In the desire of the unit to obtain better results in the extraction cycle of the pick 110, work that began to deepen and explore the continuity of the vein, this work is born from level 110 and is located 8 meters from the main pick that reaches the surface, currently in the work is necessary the presence of up to 04 workers to perform the work of drilling & blasting, cleaning the material (waste / ore) and perform the extraction in a conventional way by exerting force of the worker. This has led to the problem being posed as the inefficiency of the extraction cycle in pit 110 of the La Verdosa mining unit. For this reason, the main objective was to propose a mechanization model of the hoisting system to improve the productivity of the extraction cycle of pit 110. This investigation project has the goal to achieve improvements in the material extraction cycle, to achieve the goal it will be done statistical analysis to accomplish the achievements indicators. In addition, the area of studio will be the “PQ 110” and the “SN 110”, where time measurements were taken Field measurements were made in the mining unit, to take relevant information, process it and be able to carry out statistical analysis, with which it was obtained that the operating cost to extract a wet metric ton from SN 110 was reduced by 42.9%, this improvement was able to reach by reducing the workforce and the extra hours to complete the task. On the other hand, regarding time, the hoisting system is 7.02% faster to complete a hoisting cycle, however, due to the skip capacity of the mechanized system, it only requires 09 cycles on average to culminate with the extraction of a shot from the front.Tesi
