Abstract

Although the design studio has formally been the locus for design education, informal education approach has gained more and more acceptance in the world. Informal education, which is the education outside the confines of curricula, includes the acquisition of knowledge and skills through experience, reading, social contact, etc. Workshops cover the essential weight of this informal education. Although the role of the design workshops in architectural design education has been very limited through overall design education’s past, many schools of architecture have taken steps to consider workshops as the part of informal learning and education.

“Culture and Space in the Build environment” (CSBE) Network of IAPS have been organizing “culture and design workshop series” for graduate and post graduate students in Turkey since 2001. In these workshops, a design teaching approach based on the conceptual framework of culture and space interactions is applied. The conceptual framework developed for the architectural design education, takes three fundamental starting points for workshops as the part of informal design education: as a tool for informal design education (method), as a tool for learning & understanding culture-environment relations (content), and as a tool for awareness of different environments/contexts (scale/place). The foundation of the conceptual framework is based on the general approach that discusses the “architectural design process” with regards to environmental context and content.

Within this context the aim of the paper is to discuss and evaluate the importance and the contribution of workshops as tool for informal architectural design education. These discussions will be held on the case of IAPS-CBSE Network’s last workshop “Istanbul as a Palimpsest City and Imperfection”. In the paper, the process, the method, the content and the results of workshop studies will be discussed and evaluated.

Abstract

Purpose

Food waste occurs in every stage of the supply chain, but the value-added lost to waste is the highest when consumers waste food. The purpose of this paper is to understand the food waste behaviour of consumers to support policies for minimising food waste.

Design/methodology/approach

Using the theory of planned behaviour (TPB) as a theoretical lens, the authors design a questionnaire that incorporates contextual factors to explain food waste behaviour. The authors test two models: base (four constructs of TPB) and extended (four constructs of TPB plus six contextual factors). The authors build partial least squares structural equation models to test the hypotheses.

Findings

The data confirm significant relationships between food waste and contextual factors such as motives, financial attitudes, planning routines, food surplus, social relationships and Ramadan.

Research limitations/implications

The data comes from an agriculturally resource-constrained country: Qatar.

Practical implications

Food waste originating from various causes means more food should flow through the supply chains to reach consumers’ homes. Contextual factors identified in this work increase the explanatory power of the base model by 75 per cent.

Social implications

Changing eating habits during certain periods of the year and food surplus have a strong impact on food waste behaviour.

Originality/value

A country is considered to be food secure if it can provide its citizens with stable access to sufficient, safe and nutritious food. The findings and conclusions inform and impact upon the development of food waste and food security policies.

Abstract

Purpose

The purpose of this paper is to investigate damaging processes in TaN thin film absorbers under action of high-voltage electrical pulse of nanosecond duration. Despite having mechanical origin of crack opening, estimation based on the readings from oscillograms shows uncharacteristically high velocities of the crack propagation.

Design/methodology/approach

Microscopic images of damaged absorbers showing the final result of the damaging process provided initial information about its geometrical peculiarities. Then, to clarify the dynamics of the process, the authors create the model of the crack, having elements of self-similarities and multiple stage opening. The influence of heating induced by current concentration at crack tip and of magnetic stress of this concentrated current are both included in the model.

Findings

Using physical parameters of TaN layers with flowing current and performing calculations the authors define the conditions required to initiate the damaging process and to sustain it. Danger of such damage is relevant for high-Tc superconducting thin films after their switching to normal state which is induced by the high-voltage pulse.

Practical implications

There were made recommendations to manufactures aiming to improve electrical durability of the absorbers in an effort to prevent the damaging influence of power nanosecond electrical pulses.

Originality/value

Three stage opening model implies the appearance of zone of high-energy dissipation that can lead to detonation-like destruction of the film and, therefore, explain the high velocities of crack propagation.

Abstract

Purpose

This paper examines how firms of different sizes formulate and implement strategies to achieve fit with an external environment disrupted by a geopolitical event. The context of the study is the pharmaceutical industry and how it managed the supply chain uncertainty created by the United Kingdom's decision to leave the European Union, or Brexit.

Design/methodology/approach

Data were collected longitudinally from the pro-Brexit vote on 23 June 2016, until the UK’s departure from the EU on 31 January 2020. Twenty-seven interviews were conducted in the pharmaceutical sector, including nineteen interviews with senior managers at eight case companies and eight interviews with experts working for trade associations and standards institutes. The interview findings were triangulated with Brexit policy and strategy documentation.

Findings

When formulating strategy, multi-national enterprises (MNEs) used worst case assumptions, while large firms, and small and medium sized enterprises (SMEs) gathered knowledge as part of a “wait-and-see” strategy, allowing them to reduce perceptions of heightened supply chain uncertainty. Firms then implemented reactive and/or proactive strategies to mitigate supply chain risks.

Originality/value

The study elaborates on strategic contingency theory by identifying two important conditions for achieving strategic fit: first, companies deploy intangible resources, such as management time, to gather information and reduce perceptions of heightened supply chain uncertainty. Second, companies deploy tangible resources (supply chain redundancies, new supply chain assets) to lessen the negative outcomes of supply chain risks. Managers are provided with an empirical framework for mitigating supply chain uncertainty and risk originating from geopolitical disruptions.

Abstract

Purpose

The purpose of this paper is to examine the relationship between the stress experienced by parents during the pandemic and their cyberchondria. The research was carried out in a descriptive and cross-sectional manner.

Design/methodology/approach

The sample of the research: living in Turkey and has created 432 parents with at least one child between the ages of 6 and 15. Participant information form, parental stress scale and cyberchondria scale were used in the study. Data were collected through online surveys between July 1, 2020, and August 31, 2020.

Findings

In the study, when the scores obtained from the Parental Stress Scale and the Cyberchondria Scale were compared with the demographic characteristics, a significant difference was found between gender, age, marital status, education level, economic status, number of children and presence of chronic diseases (p < 0.05). It was determined that there is a significant difference between the responses of the parents regarding the pandemic process and the Parental Stress Scale and the Cyberchondria Scale (p < 0.05). A positive significant correlation was found between the Parental Stress Scale and the total and subdimensions of the Cyberchondria Scale (p < 0.05).

Research limitations/implications

The research was carried out with only parents with children between the ages of 6 and 15, but it reveals the stress and cyberchondria of the parents during the pandemic.

Originality/value

The results obtained reflect the factors affecting the stress and cyberchondria levels experienced by parents during the pandemic process. Also, as the stress of the parent's increases, it has seen that the level of cyberchondria increases in parallel.

Abstract

Purpose

The purpose of this paper is to test the link between servitisation and circular economy by synthesising the effect of product-service systems (PSS) on supply chain circularity (SCC).

Design/methodology/approach

Following a systematic literature review methodology, the study identified 67 studies and synthesised them using content analysis.

Findings

A conceptual model is developed illustrating how PSS business models impact SCC through increased product longevity, closure of resource loops and resource efficiency. It also identifies six contextual factors affecting the implementation of SCC including: economic attractiveness of SCC; firm sustainability strategy; policy and societal environment; product category; supply chain relationships; and technology.

Research limitations/implications

The conceptual model proposes that SCC increases with servitisation. It also proposes that the main circularity effect stems from increased product longevity, followed by closed resource loops and finally resource efficiency. The model is deduced from the literature by using secondary data.

Practical implications

The review provides practitioners with a framework to increase SCC through PSS business models. It also gives insight into the various contextual factors that may affect how a manufacturer’s servitisation strategy contributes to SCC.

Originality/value

This review contributes to the understanding of the relationship between servitisation and SCC by synthesising the different effects that exist. Moreover, it creates new knowledge by identifying a range of contextual factors affecting the relationship between PSS and SCC.

Abstract

Purpose

We conduct a multidisciplinary systematic literature review on climate neutrality in the supply chain. While carbon neutrality has gained prominence, our study argues that achieving carbon neutrality alone is not enough to address climate change effectively, as non-CO2 greenhouse gases (GHG) are potent contributors to global warming.

Design/methodology/approach

We used multiple databases, including EBSCO, ProQuest, Science Direct, Emerald and Google Scholar, to identify articles related to climate neutrality in the context of non-CO2 gases. A total of 71 articles in environmental science, climate change, energy systems, agriculture and logistics are reviewed to provide insights into the climate neutrality of supply chains.

Findings

We find that, in addition to CO2, other GHG such as methane, nitrous oxide, ozone and fluorinated gases also significantly contribute to climate change. Our literature review identified several key pillars for achieving net-zero GHG emissions, including end-use efficiency and electrification, clean electricity supply, clean fuel supply, “GHG capture, storage and utilization,” enhanced land sinks, reduced non-CO2 emissions and improved feed and manure management.

Originality/value

We contribute to the literature on climate neutrality of supply chains by emphasizing the significance of non-CO2 GHG along with CO2 and highlighting the need for a comprehensive approach to climate neutrality in addressing climate change. This study advances the understanding of climate neutrality of supply chains and contributes to the discourse on effective climate change mitigation strategies. It provides clear future research directions.

Abstract

Purpose

Digital transformation using Industry 4.0 technologies can address various challenges in food supply chains (FSCs). However, the integration of emerging technologies to achieve digital transformation in FSCs is unclear. This study aims to establish how the digital transformation of FSCs can be achieved by adopting key technologies such as the Internet of Things (IoTs), cloud computing (CC) and big data analytics (BDA).

Design/methodology/approach

A systematic literature review (SLR) resulted in 57 articles from 2008 to 2022. Following descriptive and thematic analysis, a conceptual framework based on the diffusion of innovation (DOI) theory and the context-intervention-mechanism-outcome (CIMO) logic is established, along with avenues for future research.

Findings

The combination of DOI theory and CIMO logic provides the theoretical foundation for linking the general innovation process to the digital transformation process. A novel conceptual framework for achieving digital transformation in FSCs is developed from the initiation to implementation phases. Objectives and principles for digitally transforming FSCs are identified for the initiation phase. A four-layer technology implementation architecture is developed for the implementation phase, facilitating multiple applications for FSC digital transformation.

Originality/value

The study contributes to the development of theory on digital transformation in FSCs and offers managerial guidelines for accelerating the growth of the food industry using key Industry 4.0 emerging technologies. The proposed framework brings clarity into the “neglected” intermediate stage of data management between data collection and analysis. The study highlights the need for a balanced integration of IoT, CC and BDA as key Industry 4.0 technologies to achieve digital transformation successfully.
