Abstract

Purpose

The purpose of this paper is to adopt a learning-based approach to portray the impact of Covid-19 on state school services in Italy, with a specific focus on the role of street-level bureaucrats and the triggering of co-creative processes.

Design/methodology/approach

The study proposes a qualitative system dynamics (or SD) approach describing the implementation of Covid-related educational policies in Italy. An insight model, made of causal loop diagrams, integrates the selected multi-disciplinary literature and institutional sources, secondary data from national and local reports (about Palermo, the fifth largest metropolitan city in Italy) and insights from a panel of school street–level bureaucrats.

Findings

The study provides an insight into the impacts of governmental decisions (school closures and the subsequent need to activate distance learning during the first wave of Covid-19) at a local level. Specifically, it portrays the influences of managerial and professional discretion, infrastructural equipment and socio-economic factors favouring/deterring co-creative educational processes.

Practical implications

The SD model highlights vicious/virtuous circles in policy implementation and suggests new managerial paths for education, more routed towards public value creation and less attached to bureaucratic procedures and the unquestioning application of performance culture.

Originality/value

The paper proposes an original and holistic approach to dealing with policy making in education and its managerial features. The research findings are considered important, not only to face the current emergency, but also to pro-actively think about the post-Covid era.

Abstract

Purpose

The purpose is to forward systems theory one more step towards social theory and integrate problem-solving and theory-building, and search for the integration and unity of science by revealing the nature and role of critical systems thinking (CST).

Design/methodology/approach

This article describes relations between systems theory and social theory in three parts. First, it examines the links of systems methodologies with three social science approaches as well as the role of CST. Second, the focus of theory and the form of explanation are discussed from critical social science (CSS) perspective. Third, the direction of theorizing of a CST-based systems theory is investigated.

Findings

First, CST is a hidden assumption of system dynamics (SD)/systems thinking (ST). Second, systems theory is positioned in CSS. Third, CST integrates traditional and soft systems methodologies (SSM), and connects systems science and social science. Fourth, this article reveals hidden links between systems approaches and three corresponding social science approaches. Fifth, the theoretical focus of a CST-based systems theory could be formal/structure theory and/or substantive/content theory. Sixth, the form of explanation could be structural/mechanismic explanation combining causal and interpretive explanations. Seventh, a CST-based systems theory may adopt abduction, which complements a defect in deduction and induction in a difficulty of nonlinearity.

Originality/value

It illustrates a graph of the competing approaches in systems science corresponding to paradigms in social science.

The purpose of this paper is to present a Preisach model to simulate the vector hysteresis properties of ferromagnetic materials.

Abstract

Purpose

The purpose of this paper is to present a Preisach model to simulate the vector hysteresis properties of ferromagnetic materials.

Design/methodology/approach

The vector behavior has been studied at low frequency applying a single‐sheet tester with a round‐shaped specimen, and the locus of the magnetic flux density vector has been controlled by a digital measurement system. An inverse vector Preisach hysteresis model has been developed and identified by using the measured data.

Findings

Finally, the inverse model has been inserted into a finite element procedure through the combination of the fixed point technique and the reduced magnetic scalar potential formulation. The developed single‐sheet tester measurement system has been simulated. The applicability of the realized measurement system as well as the developed model has been proven by comparing measured and simulated results.

Originality/value

The identification technique is original, based on a previous work of the author.

Abstract

Purpose

This paper aims to clarify how affect-based adaptation can improve implicit recognition of playing style of individuals during game sessions. This study presents the “Rush for Gold” game using dynamic difficulty adjustment of tasks based on both player performance and affectation inferred through electrodermal activity and facial expressions of the player. The game applies linear regression for calculating playing styles to be applied for achieving a style-based adaptation in other educational video games.

Design/methodology/approach

The experimental procedure included subject selection, demonstration, informed consent procedure, two game sessions in random order – one without and another with affective adaptation control – and post-game self-report. The experiment was conducted with participation of 30 master students and university lecturers in informatics.

Findings

This study presents experimental results concerning the impact of affective adaptation over playing style recognition, game session time, task’s effectiveness, efficiency and difficulty and, as well, player’s assessment of affectively adaptive gameplay obtained by an adaptation control panel embedded into the game and by post-game self-report.

Research limitations/implications

The proposed adaptive game limits recognised styles to such based on the Kolb’s Learning Style Inventory model. Another limitation of the study is the relatively small number of participants constrained by the extended experimental procedure and the desktop game version.

Originality/value

The paper presents an original research on the effect of affect-based adaptation on a novel approach for implicit recognition of playing styles.

Abstract

Denim fabrics of various weight ranges were sewn with three different compositions of sewing threads ‐ 100 per cent cotton, 100 per cent polyester and corespun thread ‐ with all possible ticket numbers, to examine the interaction of various fabric‐thread combinations. The sewing thread performance in terms of seam efficiency, pucker, slippage and needle cutting index was determined and the results were analysed in the light of the dimensional and mechanical properties of the fabric, thread and seam itself. Corespun threads were found to be most suitable from a seam efficiency point of view. However, other sewing parameters such as pucker, slippage and damage were adversely affected by sewing with corespun threads. Tensile properties of fabrics and threads were found to be the most important factors for sewability. Breaking strength and elongation of the fabric and sewing thread had an excellent correlation with seam efficiency. Cotton threads were found to be most suitable for sewing denim from a seam puckering point of view. On the other hand, polyester threads were more prone to develop seam pucker. Corespun thread was the greatest yarn damager compared to cotton and polyester threads. Fabric cover factor and sewing thread diameter were highly correlated with the needle cutting index.

Abstract

Purpose

This paper seeks to present a decision‐making model for manufacturers to maximize their profits in reverse logistics operations.

Design/methodology/approach

A system dynamic model has been developed to complement with prior models and is validated using data collected from a computer company manufacturer handling returns with volumes transacted over a period of two years.

Findings

The results from the model indicate that part replacements from suppliers are more profitable than refurbished computer parts. In addition, transportation delay and supplier delay in processing returns have a significant impact on the viability of reverse logistics regardless of return volumes.

Research limitations/implications

The current model is not designed for third‐party logistics (3PL) offering reverse logistics services. However, this can be accomplished by resetting some of the parameters in the model. The other limitations are exchange rate fluctuation and product depreciation which are not incorporated in the model. This is important in Asia where each country has its own currency which fluctuates with time.

Practical implications

This dynamic model will assist decision‐makers to test new policies related to reverse logistics, for example, liberal versus conservative return policy from supplier, shipment consolidation (longer delays) versus direct shipment, batch (longer delays) versus JIT remanufacturing, pricing of new parts versus re‐condition parts, as well as to examine its long‐term viability.

Originality/value

Using system dynamics to understand the profitability of reverse logistics for both replacement parts to suppliers and refurbished parts to manufacturers.

Abstract

Purpose

To produce a coated fabric, a base fabric may be completely or partially coated with a polymer layer, which changes the properties of the new system relative to the base fabric. The purpose of this paper is to analyze the influence of the thermal transfer material and its shape on the deformability of knitted fabrics during the uniaxial extension and to determine the residual deformation of the thermoplastic transfer element of coated fabrics after unloading.

Design/methodology/approach

Knitted fabrics were partially and entirely coated with heat transfer material. For partial coating, square pieces of three different transfer materials were bonded on the middle of the specimen. They were solid, perforated with either nine circular holes or six rectangular holes. A heat seal press was used to laminate knitted fabrics. The samples were subjected to uniaxial tensile testing. The characteristics such as strain at maximum force, strain at break, and strain at low stress were measured. After stretching and relaxation of the specimens, the residual deformation of the heat transfer element was also investigated.

Findings

The results indicated that coating knitted fabrics with transfer material may decrease their stretchability. The experiments show that the decrease in stretchability and in the degree of residual deformation after stretching and relaxing depend on the knitted structure, the shape of the transfer element, and the degree to which the fabric is coated.

Originality/value

This study examines the influence of heat transfer material which may be not only entirely but also partially joined with knitted fabric layer on the deformability and shape stability of this system.

Abstract

Purpose

University campuses behave as complex systems, and sustainability in higher education is best seen as an emergent quality that arises from interactions both within an institution and between the institution and the environmental and social contexts in which it operates. A framework for strategically prioritizing campus sustainability work is needed. This paper seeks to address these issues.

Design/methodology/approach

First, a conceptual model is developed for understanding institutions of higher education as systems. Second, a leverage points framework is applied to experiences at the University of Vermont in order to evaluate campus sustainability efforts. Finally, real‐world examples are used to analyze and prioritize campus sustainability leverage points for advancing organizational change.

Findings

This systems thinking approach identifies key leverage points for actions to improve sustainability on campus. The leverage points framework is found to be valuable for: evaluating the potential of individual programs or actions to produce system‐wide change; coordinating individual programs into a strategic effort to improve the system; and making connections between campus and the surrounding social and environmental contexts. Advancing campus sustainability is found to be strengthened by particular ways of thinking and an organizational culture committed to continuous improvements and learning improved ways of doing business based on environmental and social, as well as institutional, benefits.

Originality/value

Campus sustainability workers must develop a prioritization process for evaluating which ideas to move forward on first. Systems thinking can cultivate our ability to consciously redesign and work with the systems that are in place, to intentionally pursue organizational improvements, and to plan and coordinate sustainability programs with potential for big changes.

Abstract

Purpose

The purpose of this paper is to present personal experiences of using storytelling as a “sensemaking” tool, to argue for the benefits of this method as a process of better understanding the gendered academy and the role storytelling can play in effecting change.

Design/methodology/approach

Drawing on personal experiences of storytelling within workplaces, the paper explores how stories between colleagues can lead to positive change through the co‐construction of new worlds of meaning which are spontaneously revised through interaction.

Findings

The paper demonstrates how storytelling between individuals experiencing inequality makes visible the gendered practices in academic workplaces and can lead to a change in those experiences of the workplace. Also, such stories can be a means for prompting change through negotiation. Theoretically, a triple‐loop learning environment within an organization could provide the agora required for stories about inequality to be heard continually and change to come about through negotiation.

Research limitations/implications

The paper uses a method that serves as a heuristic device and as such cannot be generalized for all organizational settings. The findings offer a new but partial solution for negotiating gender inequity in academia by suggesting that there must be more storytelling in openly public spaces between colleagues to challenge and negotiate the gendered organizational cultures of academia.

Practical implications

The application of the method of triple‐loop learning in academic organizational settings can assist in challenging and changing gender inequity through the consistent use of narratives.

Originality/value

The paper is unique in that it argues for the value of a self‐reflexive narrative form of method which favours stories being shared in public spaces – the agora – as a way of addressing gender inequity within complex, male dominated professions such as academia.
