Digital transformation challenges in higher education institutions post COVID-19

Higher education institutions (HEIs) encountered an unanticipated and unprepared digital transformation because of COVID-19, which obliged most services, including teaching, learning, and working, to shift from physical to digital and virtual platforms. Digital transformation among employees provided an opportunity for technological upgrades and challenged technological competence and adaptability among employees to enable transitions between physical and virtual platforms. As a result, this paper through the technology acceptance model (TAM) reflects on factors that influence successful transformation of technological adoption among support staff members in a university of technology (UOT). This paper argues that the use of TAM to predict staff members’ attitudes toward adopting new technology can assist HEIs in decision-making regarding technology selection. Using descriptive research design and non-probability sampling method, data was collected from 177 support staff members from different departments. The findings of the study, which emanated from surveys, established that employees’ digital skills need improvement; lack of digital infrastructure funding; poor planning and unclear forms of communication proved to be a recipe for failure to implement a successful digital shift and in creating acceptance digital user behaviour among the employees.

The Utility of “Industry 4.0” for Economic Development and Industrial Structure Change in Germany

Abstract Germany’s “Industry 4.0” strategy is a technological revolution that accelerates full penetration into industrial fields such as manufacturing, mainly based on the Internet of Things and the rapidly developing new generation of Internet technology as a carrier. This paper examines the implementation of Germany’s “Industry 4.0” strategy, focusing on R&D expenditures, capacity utilization rates, and CNC rates of key processes in the manufacturing industry. It also lays the groundwork for Germany’s economic development and the effects of industrial restructuring. We construct a regression model to analyze the impact of “Industry 4.0” on the German economy, using economic growth as a measure of economic development. We use the automobile industry as a representative to study the industrial restructuring and upgrading of Germany under the “Industry 4.0” strategy. The results demonstrate a positive correlation between the estimated coefficients of economic growth variables in each year from 2020 to 2022 and the industry’s value-added, passing the significance test at the 0.05 level. In the industrial restructuring, Germany’s automobile industry has realized the transformation from traditional manufacturing mode to intelligent manufacturing mode, and the 1387.2 billion euros of Volkswagen’s R&D investment also shows that Germany is still pursuing the technological upgrading of the industry.

Impact of Industry 4.0 Technologies on Operations Resilience: Adverse Effects of COVID-19 as a Moderator

In the era of Industry 4.0, manufacturing firms are focused towards implementing a broad range of Industry 4.0 technologies and expect those technologies to shield them from disruptions. Rapid technology upgrades, adoption of new technologies and digitalised operations have been common during the COVID-19 pandemic, where remote working labour, skill shortages, supply shortages, and demand issues caused operations uncertainties. This study investigates the effects of Industry 4.0 technologies and incremental innovation on the operations resilience of Australian manufacturing firms operated under various COVID-19 challenges. Based on survey data collected from 117 manufacturing firms, it finds that Industry 4.0 capabilities lead to operations resilience only through incremental innovations and that COVID-19 effects moderate the relationship between Industry 4.0 capabilities and operations resilience. There was no empirical evidence for the moderating role of COVID-19 effects on the relationship between incremental innovation and operations resilience. Based on the findings, we argue that Industry 4.0 capabilities translate stronger into operations resilience for firms that experience substantial adverse effects than for those that experience lower negative effects. Our results confirm the benefits of manufacturing firms investing in a broad range of Industry 4.0 technologies to achieve operations resilience in highly disrupted environments where the survival of firms is threatened and the importance of developing capabilities for incremental innovation. Our findings assure managers of manufacturing firms of the benefits of technology investments and provide a rationale for those weighing alternatives to achieve operations resilience.

The dark side of the boom: Dutch disease, competition with China, and technological upgrading in Colombian manufacturing

The natural resource boom of the 2000s spurred growth in income and consumption in many commodity-exporting nations. However, this paper brings together a previously unused combination of data sets from Colombia to document evidence of a downside – the currency appreciation associated with this boom led to a significant and persistent decline in R&D spending and in investment in technological upgrading by Colombian manufacturing firms. Our empirical strategy exploits differences in firms' sales across products and export destinations to create firm-specific measures of exposure to exchange rate shocks both abroad and at home. We link these new measurements of exchange rate exposure with Colombian micro data on R&D investment and technology upgrading. The key finding is that real exchange rate appreciation drives significant reductions in both firm-level R&D investment and a measure of technology upgrading that includes expenditure on capital goods, technology licensing, worker training, and other expenditures related to the adoption of new technology. Even after key commodity prices dropped significantly in the mid-2010s, inducing a substantial and long-lasting Colombian currency depreciation, investments in R&D and technology upgrading remained at subdued levels. Our estimated effects suggest that the resource boom and associated appreciation had a significant and persistent negative effect on technological development of Colombian manufacturing firm, and these conclusions remain even after careful attempts to simultaneously control for rising competition with Chinese manufacturers, which also had a negative effect on Colombian firms' technology investments, and the effects of trade liberalization at home and abroad. Similarities between Colombia and other commodity-exporters suggest that the effects documented in this paper may be widespread.

A green strategy for upcycling utilization of core parts from end-of-life vehicles (ELVs): Pollution source analysis, technology flowchart, technology upgrade

The disposal of end-of-life vehicles (ELVs) is an issue of great concern to the society, because of its huge amount, resource value and environmental pollution. A wide variety of pollutants generate and release during the recycling process. However, previous studies are piecemeal and segmentary, the correlation between treatment flowchart and pollution is unknown, and pollution source analysis in ELV recycling and core parts (engine, gear box, etc.) remanufacturing bases is still a challenge. In this study, the aim is to propose a green strategy for upcycling utilization of ELV part based on pollution source analysis, technology flowchart, and technology upgrade. We synthetically analyzed current typical ELV dismantling and core part remanufacturing processes of ELVs. A total of 36 volatile organic compound (VOC) species and 7 heavy metals were found in dismantling process, and 61 VOC species were detected in remanufacturing process. Based on statistical analysis and treatment process characteristics, 18 pollution fingerprints were constructed. At last, an intelligent dismantling and upcycle utilization line for ELVs has been developed to improve production efficiency and reduce pollution release.

Stabilization of isolated hybrid microgrids with electric vehicle-based energy storage systems using a fractional order proportional-integral-derivative control

ABSTRACT Electric vehicles (EVs) are considered to be the most promising technology upgrades in the coming years to reduce the carbon emission, since the EVs could replace the conventional combustion vehicles as well as mitigate power fluctuations in power grids. This paper focuses on addressing the frequency stability issues in isolated hybrid grids (IHGs) by introducing a fractional order proportional-integral-derivative (FOPID) control for grid-connected power converters. A particle swarm optimization (PSO) technique is adopted to optimize the parameters of the controllers. The advantages of the proposed control method over the conventional proportional-integral-derivative (PID) control, proportional-integral with proportional-derivative (PI-PD) control, and proportional-integral-derivative with filter (PIDF) control schemes are verified by simulation case studies. Besides, a modified virtual rotor concept (MVRC) is proposed in this paper to enhance the inertia of the system. Furthermore, the performance of using EVs to regulate the frequency of IHGs is compared to the superconducting magnetic energy storage (SMES) units, capacitive energy storage (CES) units, and redox flow batteries (RFB) under fixed and variable load conditions.

This study delves into the evolving landscape of smart city development in Kazakhstan, a domain gaining increasing relevance in the context of urban modernization and digital transformation. The research is anchored in the quest to understand how specific technological factors influence the formation of smart cities within the region. To this end, the study adopts a Spatial Autoregressive Model (SAR) as its core analytical tool, leveraging data on server density, cloud service usage, and electronic invoicing practices across various Kazakhstani cities. The crux of the research revolves around assessing the impact of these selected technological variables on the smart city development process. The SAR model’s application facilitates a nuanced understanding of the spatial dynamics at play, offering insights into how these factors vary in influence across different urban areas. A key finding of this investigation is the significant positive correlation between the adoption of electronic invoicing and smart city development, a result that stands in contrast to the relatively insignificant impact of server density and cloud service usage. The conclusion drawn from these findings underscores the pivotal role of digital administrative processes, particularly electronic invoicing, in driving the smart city agenda in Kazakhstan. This insight not only contributes to the academic discourse on smart cities but also holds practical implications for policymakers and urban planners. It suggests a strategic shift towards prioritizing digital administrative innovations over mere infrastructural or technological upgrades. The study’s outcomes are poised to guide future smart city initiatives in Kazakhstan and offer a reference point for similar emerging economies embarking on their smart city journeys.

Selective Oxidation Using In Situ-Generated Hydrogen Peroxide.

ConspectusHydrogen peroxide (H2O2) for industrial applications is manufactured through an indirect process that relies on the sequential reduction and reoxidation of quinone carriers. While highly effective, production is typically centralized and entails numerous energy-intensive concentration steps. Furthermore, the overhydrogenation of the quinone necessitates periodic replacement, leading to incomplete atom efficiency. These factors, in addition to the presence of propriety stabilizing agents and concerns associated with their separation from product streams, have driven interest in alternative technologies for chemical upgrading. The decoupling of oxidative transformations from commercially synthesized H2O2 may offer significant economic savings and a reduction in greenhouse gas emissions for several industrially relevant processes. Indeed, the production and utilization of the oxidant in situ, from the elements, would represent a positive step toward a more sustainable chemical synthesis sector, offering the potential for total atom efficiency, while avoiding the drawbacks associated with current industrial routes, which are inherently linked to commercial H2O2 production. Such interest is perhaps now more pertinent than ever given the rapidly improving viability of green hydrogen production.The application of in situ-generated H2O2 has been a long-standing goal in feedstock valorization, with perhaps the most significant interest placed on propylene epoxidation. Until very recently a viable in situ alternative to current industrial oxidative processes has been lacking, with prior approaches typically hindered by low rates of conversion or poor selectivity toward desired products, often resulting from competitive hydrogenation reactions. Based on over 20 years of research, which has led to the development of catalysts for the direct synthesis of H2O2 that offer high synthesis rates and >99% H2 utilization, we have recently turned our attention to a range of oxidative transformations where H2O2 is generated and utilized in situ. Indeed, we have recently demonstrated that it is possible to rival state-of-the-art industrial processes through in situ H2O2 synthesis, establishing the potential for significant process intensification and considerable decarbonization of the chemical synthesis sector.We have further established the potential of an in situ route to both bulk and fine chemical synthesis through a chemo-catalytic/enzymatic one-pot approach, where H2O2 is synthesized over heterogeneous surfaces and subsequently utilized by a class of unspecific peroxygenase enzymes for C-H bond functionalization. Strikingly, through careful control of the chemo-catalyst, it is possible to ensure that competitive, nonenzymatic pathways are inhibited while also avoiding the regiospecific and selectivity concerns associated with current energy-intensive industrial processes, with further cost savings associated with the operation of the chemo-enzymatic approach at near-ambient temperatures and pressures. Beyond traditional applications of chemo-catalysis, the efficacy of in situ-generated H2O2 (and associated oxygen-based radical species) for the remediation of environmental pollutants has also been a major interest of our laboratory, with such technology offering considerable improvements over conventional disinfection processes.We hope that this Account, which highlights the key contributions of our laboratory to the field over recent years, demonstrates the chemistries that may be unlocked and improved upon via in situ H2O2 synthesis and it inspires broader interest from the scientific community.

Environmental regulation and firms' emission reduction – The policy of eliminating backward production capacity as a quasi-natural experiment

This study examines the effects of environmental regulations on firms' emission reductions. Using the Eliminating Backward Production Capacity policy in China as a quasi-natural experiment, our matching difference-in-differences estimation shows that the policy significantly reduces the sulfur dioxide (SO2) intensity of regulated firms by 5%. The results remain robust across different specifications and alternative outcome variables. The mechanism test results show that the reduction in SO2 intensity results from a smaller reduction in total output than in total SO2 emissions or energy consumption. This effect is particularly pronounced in regions with stronger motivation to reduce emissions, less fiscal pressure, and higher levels of air pollution, as well as in the central and western regions. Furthermore, this study finds a pollution leakage from regulated firms to other local firms. The larger the size of other local firms, the more pronounced the increase in their output. Overall, we find a 50% rebound in pollution due to leakage. However, as the policy also increases total output by 187%, our results indicate that the policy is effective in substituting backward with advanced production capacity. Our findings provide empirical evidence regarding the use of command-and-control policies to adjust the technological structure of production for technological upgrading and environmental improvement. This provides a valuable reference for developing countries to consider similar policies.

SCC can significantly improve destination TE, and the impact of SCC on destination TE has spatially heterogeneous.

Synthesis and Environmental Applications of Nanoporous Materials Derived from Coal Fly Ash

Coal fly ash (CFA) is the primary solid waste generated by the coal-fired industry, and the predominant treatment methods include accumulation, landfill, and the production of cement-based building materials. However, the availability of these methods is relatively limited, and there is a need for technological upgrades. The extensive accumulation not only leads to environmental pollution but also has detrimental effects on human health. With its loose structure and main chemical components of Al2O3 and SiO2, CFA is conducive to the synthesis of promising nanoporous materials for applications in adsorption. The use of CFA as a raw material can significantly reduce preparation costs, improve comprehensive utilization efficiency, and manufacture more valuable products, aligning with the current strategy of sustainable development. Currently, the most widely used synthesis method is hydrothermal synthesis. This review focuses on the principles, methods, and influencing factors of synthesis, with particular emphasis on CFA-based mesoporous silica, zeolites, and metal–organic frameworks (MOFs), which have not been systematically reviewed previously. The quality of these synthesized nanoporous materials can be finely adjusted through the synthesis process. A comparison of the advantages and disadvantages of each process will be made, and the impact of the synthesis conditions on the synthetic products will be analyzed. Additionally, a brief discussion on the latest research advances in their applications in adsorption will be provided. Finally, relevant challenges and issues have been proposed.

A simulation and risk assessment framework for water-energy-environment nexus: A case study in the city cluster along the middle reach of the Yangtze River, China

In the Anthropocene, there is a strong interlinkage among water, energy, and the environment. The water-energy-environment nexus (WEEN) has been vigorously advocated as an emerging development paradigm and a global research agenda. Based on the nexus concept, a framework for the WEEN complex system simulation and risk assessment is developed. The three metropolitan areas of the city cluster along the middle reaches of the Yangtze River (CCMRYR) are taken as the objects. Regional policies are combined with generic shared socio-economic pathways (SSPs) to form a localized SSPs suitable for the research region. The dynamic simulation of the WEEN complex system and the risk analysis are carried out with the combination of system dynamics models and copula functions. Results show that: There are obvious differences in water utilization, energy consumption, air pollutant emissions, and water pollutant emissions among the three metropolitan areas. The issue of high carbon intensity in the Wuhan Metropolitan Coordinating Region needs to be emphasized and solved from the perspective of optimizing the industrial structure. Adhering to current development patterns, there will be successive peaks in water utilization, energy consumption, and carbon emissions in Wuhan, Dongting Lake, and Poyang Lake Metropolitan Coordinating Region by 2030, leading to high synergy risks at the systemic level, with maximum values of 0.84, 0.85, 0.62, respectively. A development path based on conservation priorities indicates that future policymaking needs to prioritize a resource-saving and pollution-control development pattern directed by technological upgrading against the backdrop of scarce natural resource endowments. The localized SSPs are a beneficial extension that enriches the narrative of regional-scale SSPs. The evolutionary trajectories and risk assessments of WEEN complex systems under different localized SSPs provide a sweeping insight into the consequences of policy decisions, thus enabling policymakers to appraise policy rationality and implement appropriate corrective measures.

Enhancing Borehole Hydraulic Performance: Integrating Technological Upgrades into Borehole Design and Construction Case Studies of Unconsolidated Aquifers in Israel

In recent years, significant modifications and improvements have been instituted in the technical configuration of substituted boreholes compared with old boreholes. Augmenting the production capabilities of individual boreholes and borehole fields has notable engineering and economic implications. Regrettably, altering the composition of the aquifer lithology and its inherent hydraulic properties remains beyond our control. Consequently, the augmentation of extraction capabilities from individual boreholes hinges upon the implementation of technical enhancements in drilling methodologies, borehole design, and ultimate borehole structure. This phenomenon is elucidated through illustrative instances drawn from two distinct aquifer basins. The substituted boreholes were drilled within the same yard, to equivalent depths and into lithological formations similar to those encountered in the old boreholes. The strides made in borehole structural technology bear remarkable significance in influencing the outcomes of pumping tests, with a specific emphasis on the estimation of aquifer loss (B) and well loss (C) coefficients. These advancements substantially contribute to heightened well efficiency, elevated specific yield, and diminished dynamic drawdown. Our extensive professional expertise prompted us undertake a qualitative ranking of the constituent technical elements based on their relative significance and ensuing impact on the improvement of hydraulic parameters and pumping efficiency. The prioritization of significance manifests as follows: screen length, gravel pack composition (Glass beads or sorted quartz gravel), screen diameter, percentage of screen open area, and screen material composition. This article assumes a distinctive and pioneering character as it constitutes a primary endeavor to comprehensively investigate in parallel both the technical conception and construction of boreholes and their subsequent hydrological performance. The overarching message gleaned from this study underscores that the infusion of innovation into borehole design and construction can serve as the pivotal determinant separating a borehole characterized by modest hydraulic performance from one characterized by exceptional hydraulic performance.
