Abstract

Purpose

The purpose of this study is to identify global trends in disruptive technological change and map the social and policy implications, particularly as they relate to the educational ecosystem and main stakeholders across all levels of education.

Design/methodology/approach

The authors conducted a two-stage meta-analysis of 1,155 scholarly, peer-reviewed articles. The investigation involves a systematized literature review for data identification and collation adhering to defined selection criteria, and a network analysis to scrutinize data, consolidate information and unveil correlations and patterns from the literature review to produce a set of recommendations.

Findings

The study unveiled educational trends related to disruptive technologies and delineated four principal clusters representing how these technologies are transforming the education ecosystem. Additionally, a series of transversal aspects that reveal a societal vulnerability toward future prospects in the realms of ethics, sustainability, resilience, security, and policy were identified.

Practical implications

The findings spotlight an enlarging chasm between industry (and society at large) and conventional education, where many transformations triggered by disruptive technologies remain absent from teaching and learning systems. The study further offers recommendations and envisions potential scenarios, urging stakeholders to respond based on their positions concerning disruptive technologies.

Originality/value

Expanding from the meta-analysis of pertinent literature, this paper offers four collections of curated resources, four mini case studies and four scenarios for policymakers and local communities to consider, enabling them to plot courses for their optimal futures.

Abstract

Purpose

This study explores the potential of paradox theory as a novel theoretical lens to investigate persistent and interdependent tensions in supply chains. It is based on a critical literature review focusing on paradoxes observed within complex supply chains in dynamic business environments, including the articles selected for this special issue, “Environmental Dynamism and Supply Chain Complexity: Managing the Paradoxes.”

Design/methodology/approach

This study introduces the key concepts and themes of the paradox theory literature and possible methodological approaches to studying paradoxes in supply chains. Through a literature review, this study also reflects on the current state of paradox research in the field of operations and supply chain management (OSCM) and proposes future research questions.

Findings

The application of paradox theory to OSCM research is in its early stages. This paper presents opportunities to explore persistent and interdependent tensions in supply chains using paradox theory.

Research limitations/implications

The paper suggests several new research questions that should be translated into more precise propositions. The main implication for research is a call to focus attention on how and why a paradox perspective can help supply chain researchers view complex supply chain problems with fresh eyes.

Originality/value

The study provides the first critical review of paradoxical tensions in OSCM research. While the papers in this special issue contribute significantly to a better understanding of these issues, there is still significant potential for understanding how to respond to paradoxes in supply chains.

Abstract

Purpose

The goal of the study is to underline “Cinematic Architecture” as another source of architectural thinking and research. This study is also a response to the shortage in empirical research on architecture in the cinema. Moreover, the study introduces the architectural components that qualify the cinematic spaces to be influential cinematic experience. This is in addition to investigating the impact of these components on the viewers' cognitive and emotional experience of films.

Design/methodology/approach

In the reported study, an empirical experiment examined scenes from three different movies as experienced by a selected group of audience of movies fans (architects and laypersons). The audience was asked to report feelings the audience had about each scene using a questionnaire that was designed for this purpose, and the audience was asked to write down the aspects that affected the audience's emotions. The experiment evaluated selected emotional states and could specify the architectural features and/or objects that significantly contributed in inducing these emotions.

Findings

This study's findings concluded that emotions, which exist in the positive margin of the emotions “circumplex model,” were influenced by architectural components that were different from those that influenced emotions which lie in the negative margin of the model.

Research limitations/implications

As for filmmakers, the study contributes in developing filmmakers' knowledge about the role of architecture in scenic creation and thus how that knowledge enhances filmmakers' film narrative and the narrative's spatial imagery. As for academia, this study contributes in developing the knowledge about film cognition as related to architectural semiotics. In the context of behavioral approach to architectural design, a behavior setting which is the basic element in environmental design can be dramatized by applying a cinematic narrative to a human activity system within a milieu of architectural design elements.

Practical implications

This study is important for architects, as the study provides architects with an alternative tool for fictional experience and for testing architectural ideas through cinematic architecture. This study also helps in developing new venues for the practice of architecture into the world of fiction. This study also contributes in developing the trend that architectural design thinking can learn from cinematic thinking and practice.

Originality/value

This study introduces an empirical approach to evaluate architectural entities as part of cinematic experience. This study also comes as a response to the shortage in empirical research on architecture in the cinema.

Abstract

Purpose

This study proposes a predictive neural network model reference decoupling control method for the coupling problem between the leg joints of hydraulic quadruped robots, and verifies its decoupling effect..

Design/methodology/approach

The machine–hydraulic cross-linking coupling is studied as the coupling behavior of the hydraulically driven quadruped robot, and the mechanical dynamics coupling force of the robot system is controlled as the disturbance force of the hydraulic system through the Jacobian matrix transformation. According to the principle of multivariable decoupling, a prediction-based neural network model reference decoupling control method is proposed; each module of the control algorithm is designed one by one, and the stability of the system is analyzed by the Lyapunov stability theorem.

Findings

The simulation and experimental research on the robot joint decoupling control method is carried out, and the prediction-based neural network model reference decoupling control method is compared with the decoupling control method without any decoupling control method. The results show that taking the coupling effect experiment between the hip joint and knee joint as an example, after using the predictive neural network model reference decoupling control method, the phase lag of the hip joint response line was reduced from 20.3° to 14.8°, the amplitude attenuation was reduced from 1.82% to 0.21%, the maximum error of the knee joint coupling line was reduced from 0.67 mm to 0.16 mm and the coupling effect between the hip joint and knee joint was reduced from 1.9% to 0.48%, achieving good decoupling.

Originality/value

The prediction-based neural network model reference decoupling control method proposed in this paper can use the neural network model to predict the next output of the system according to the input and output. Finally, the weights of the neural network are corrected online according to the predicted output and the given reference output, so that the optimization index of the neural network decoupling controller is extremely small, and the purpose of decoupling control is achieved.

Abstract

Development theory in college describes and explains how students develop. This chapter explores ways to balance and consolidate differentiation and integration in this theory. First, it traces the origins, history and current development of the theory, which evolves from an integrative understanding to a differentiated one. Subsequently, it identifies the tensions between integration and differentiation in this evolution. This chapter consider two directions towards the theoretical consolidation of differentiation and integration: (1) returning to how integrative understandings were achieved and exploring research directions that further advance integrative understandings; (2) recognizing the parallel evolution of North American student development theory in theorising about learning from a critical realism perspective, and, by overlaying this theory upon such a perspective, reconstructing it towards consolidation. This chapter concludes by discussing two implications for further higher education research that draws on student development theory.

Abstract

Purpose

Traditional Korean buildings do not differ significantly in form or structural style according to era or building type. The authors interpret this from a generative rather than a typological perspective. The generation perspective considers factors forming the buildings and is connected to the prevailing thoughts of the era.

Design/methodology/approach

This study analyzes the generation method of seowon facilities in the Joseon Dynasty (1392–1897), focusing on the Dosan Seowon. Based on Koreans' long-term thinking, the authors applied the extracted architectural space generation layers for analysis, and present an integrated method of generation layers when the Dosan Seowon was built.

Findings

The immanent, physical and body perceptual layers presented for seowon formation analysis are represented by thought, form and territory. Specific aspects of these layers in the Dosan Seowon are analyzed, including the architectural arrangement that connects the land conditions with neo-Confucian courtesy and order, the collective architectural form considering the energy of yin and yang, and the elements of objects that affect the human body perception. This form of architecture was closely linked with and strongly influenced by monistic philosophy.

Social implications

After the Korean War, architects judged traditional buildings only by shapes, and quickly accepted Western architecture's forms. Presenting a generative perspective of traditional Korean architecture expands the theoretical research direction of modern succession.

Originality/value

This is the first attempt to examine the generation method based on the Dosan Seowon's generation layers.

Abstract

Mohammad Azharuddin's arrival in professional cricket served, to quote Karl Marx, as a reform of consciousness that awakened the sport ‘from its dream about itself’. His expertise with the bat invoked the wide expanse of human sensorium, provoking reactions of shock and admiration among observers. In this chapter, I examine Azharuddin's life in cricket and public through a dialectical probing of the relationship between shock and aesthetics. Azhar and cricket appear as a productive terrain to carry out the analysis, as it pushes the possibility of what or who can be considered as a valid subject for theoretical scrutiny. Taking cues from Walter Benjamin and CLR James, I theorise the shock effects created by a cricketer most unusual. From his wristy wizardry with the bat to his appointment as captain of the Indian men's cricket team during the rise of Hindu nationalism in the country, Azharuddin's presence and popularity extended beyond the boundaries that are often imposed on a sportsperson. Through his involvement in the match-fixing scandal that was exposed at the turn of the 21st century, Azhar (the name by which he was popularly known) challenged the mores of a game that had emphasised Victorian notions of purity on and off the field. For the purposes of this chapter, I discuss how Azhar constructed a bodily discourse that pushes us to reassess our very notions of art and aesthetics.

Abstract

Purpose

The purpose of this paper was to study laminar fluid flow and convective heat transfer in a conical gap at small conicity angles up to 4° for the case of disk rotation with a fixed cone.

Design/methodology/approach

In this paper, the improved asymptotic expansion method developed by the author was applied to the self-similar Navier–Stokes equations. The characteristic Reynolds number ranged from 0.001 to 2.0, and the Prandtl numbers ranged from 0.71 to 10.

Findings

Compared to previous approaches, the improved asymptotic expansion method has an accuracy like the self-similar solution in a significantly wider range of Reynolds and Prandtl numbers. Including radial thermal conductivity in the energy equation at small conicity angle leads to insignificant deviations of the Nusselt number (maximum 1.23%).

Practical implications

This problem has applications in rheometry to experimentally determine viscosity of liquids, as well as in bioengineering and medicine, where cone-and-disk devices serve as an incubator for nurturing endothelial cells.

Social implications

The study can help design more effective devices to nurture endothelial cells, which regulate exchanges between the bloodstream and the surrounding tissues.

Originality/value

To the best of the authors’ knowledge, for the first time, novel approximate analytical solutions were obtained for the radial, tangential and axial velocity components, flow swirl angle on the disk, tangential stresses on both surfaces, as well as static pressure, which varies not only with the Reynolds number but also across the gap. These solutions are in excellent agreement with the self-similar solution.

Abstract

Purpose

The purpose of this paper is to test and analyze the friction torque of double-row angular contact ball bearings under vacuum or ordinary pressure environment, horizontal or upright installation mode, and different rotational speeds, and to provide theoretical bases for the development of aerospace equipment.

Design/methodology/approach

The experiments were carried out to investigate the effects of vacuum or ordinary pressure environment, horizontal or upright installation mode and different rotational speeds on bearing friction torque. To explore the relationship between working conditions and bearing friction torque, firstly, based on the generation source of friction torque, the test principle was determined, a test system was developed and the reliability of data was verified. Secondly, the friction torque of bearing was tested, and the values under various working conditions were obtained. Finally, this paper compared and discussed the test results.

Findings

The test results show that the friction torque value of vacuum environment horizontal installation condition is the largest at different rotational speeds, and the rotational speed has the most significant influence on the friction torque.

Originality/value

The friction torque test system of double-row angular contact ball bearing under vacuum environment was designed and built. The influence rules of vacuum or ordinary pressure environment, horizontal or upright installation mode and different rotational speeds on bearing friction torque were obtained.
