Abstract

Purpose

Cold supply chain technology is critical for extending the shelf life of perishable leafy green vegetables. This study aims to investigate the concept of managing leafy green products using cold supply chain technology and visualise the findings.

Design/methodology/approach

Using expert interviews and data visualisation approaches, this study examines how organisations deal with the complexity of cold supply chain processes and networks. Thematic data analysis was conducted. Two types of software were used to accomplish the research objectives. The first software used AntConc version 3.5.8 with word frequency (N-gram) analysis, whereas the second software, VOSViewer offered co-occurrence network visualisation and cluster analysis.

Findings

The findings show that the appropriate design of cold chain technology is critical in ensuring the freshness and quality of leafy green vegetables. The primary goal of managing the complexity of the cold supply chain is to achieve product freshness and energy efficiency. Regardless of the importance of energy efficiency, cold supply chains require warehouse management solutions for transportation and storage.

Practical implications

This study found that proper design and selection of appropriate technology in the cold supply chain have driven the companies to improve the firms’ competitive advantage while delivering the best quality of perishable leafy green food products. In addition, the freshness, quality, safety, and health of leafy green vegetables will be determined by the company’s capacity to handle long-distance transportation and select the appropriate distribution channels and storage. Warehouse management system technology was found to be secondary compared to cold chain technology, although distribution and warehousing practices are critical for supply chain performance.

Originality/value

This study has established the conceptual indicators based on best practices and outcomes for the cold supply chain. This study argued that cold supply chain management and performance should be monitored independently. Furthermore, the theory of technological adoption can be expanded to include product nature as a driver. Finally, this study has established cold chain best practices based on a perishable supply chain perspective. The findings of this study can promote healthy foods to solve zero hunger and achieve sustainable development goals. Although this study demonstrates that technology improves supply chain practises, cold storage and logistics benefit the most from technological advancements. In contrast, non-cold supply chains benefit from technology-driven improvements in performance.

The aim of this study was to analyze the effects of carbon reduction efforts and preservation efforts on system benefits in the cold chain industry of fresh products.

Abstract

Purpose

The aim of this study was to analyze the effects of carbon reduction efforts and preservation efforts on system benefits in the cold chain industry of fresh products.

Design/methodology/approach

This study develops an optimal decision game model for the fresh products in the cold chain, incorporating the retailer's preservation effort and the supplier's carbon emission reduction effort. It quantifies the relationship between carbon emission reduction effort, preservation effort and system profit. The model considers parameters like carbon trading price, consumer low-carbon preference and consumer freshness preference, reflecting real-world conditions and market trends. Numerical simulations are conducted by varying these parameters to observe their impact on system profit.

Findings

Under the carbon cap-and-trade policy, the profit of the fresh cold chain system is higher than that of the fresh cold chain system without carbon constraints, and the profit of the supplier under decentralized decision-making is increased by nine times in the simulation results. The increase in carbon trading prices can effectively improve the freshness level of fresh products cold chain, carbon emission reduction level and system profit.

Originality/value

This study comprehensively considers the factors of freshness and carbon emission reduction, provides the optimal low-carbon production decision-making reference for the fresh food cold chain and promotes the sustainable development of the fresh food cold chain.

The main purpose of this paper was to evaluate the validation process of food safety control measures.

Abstract

Purpose

The main purpose of this paper was to evaluate the validation process of food safety control measures.

Design/methodology/approach

The validation of control measures has been analyzed at 50 food companies in Serbia. The sample included companies that produce food of both plant and animal origin and have certified food safety management systems. A total of 156 control measures that combat physical hazards (41.6%), followed by microbial hazards (34.0%) and chemical hazards (24.4%), have been analyzed. To enable quantification of the validation protocols, each control measure was assigned a score.

Findings

The validation scores showed that the highest level of validation was observed in large companies, as opposed to small and medium-sized companies (p < 0.05). The type of food safety hazards and the food sector did not reveal any statistical differences in-between the scores. The main approach to validating control measures was referring to the technical documentation of equipment used (52.6%), followed by scientific and legal requirements (30.7%). Less than 20% of the analyzed control measures were validated with operational data collected on-site. No mathematical modeling was observed for the sampled food companies. Future steps should include the development of validation guides for different types of control measures and training modules.

Practical implications

This study can serve as an improvement guide for food safety consultants, food safety auditors, certification bodies, inspection services, food technologists and food managers.

Originality/value

This study is one of the first to provide an insight into how food companies validate their control measures to combat microbial, chemical and physical food safety hazards.

Abstract

Purpose

The purpose of this study is to achieve lower and lower temperature as infrared sensors works faster and better used for space application. For getting good quality images from space, the infrared sensors are need to keep in cryogenic temperature. Cooling to cryogenic temperatures is necessary for space-borne sensors used for space applications. Infrared sensors work faster or better at lower temperatures. It is the need for time to achieve lower and lower temperatures.

Design/methodology/approach

This study presents the investigation of the critical Stirling cryocooler parameters that influence the cold end temperature. In the paper, the design approach, the dimensions gained through thermal analysis, experimental procedure and testing results are discussed.

Findings

The effect of parameters such as multilayer insulation, helium gas charging pressure, compressor input voltage and cooling load was investigated. The performance of gold-plated and aluminized multilayer insulation is checked. The tests were done with multilayer insulation covering inside and outside the Perspex cover.

Practical implications

By using aluminized multilayer insulation inside and outside the Perspex cover, the improvement of 16 K in cool-down temperature was achieved. The cryocooler is charged with helium gas. The pressure varies between 14 and 18 bar. The optimum cooling is obtained for 17 bar gas pressure. The piston stroke increased as the compressor voltage increased, resulting in total helium gas compression. The optimum cool-down temperature was attained at 85 V.

Originality/value

The cryocooler is designed to achieve the cool-down temperature of 2 W cooling load at 100 K. The lowest cool-down temperature recorded was 105 K at a 2 W cooling load. Multilayer insulation is the major item that keeps the thermal radiation from the sun from reaching the copper tip.

Abstract

Purpose

Due to the recent disruptions caused by COVID-19, global supply chains are stress tested. The affected supply chains have interfered with market tonnage prices for the yield of perishable products like mangoes that are highly dependent on their quality. This research, through empirical findings, thus determines and comprehends the factors influencing mango quality (size).

Design/methodology/approach

A framework is developed for finding the potential factors of quality building on the previous literature and studies on the available topic. The data collection included face-to-face interviews comprising 240 farmers, hired managers and preharvest contractors in India's Jangaon, Rangareddy and Yadadri Bhuvanagiri districts of Telangana state. The data analysis is done using multiple regression, and the outcomes form the basis of the design of the experiments model.

Findings

The empirical insights support that the quality of mango is affected by factors such as the number of picking cycles, the cost of fertilizer, the variety of fertilizers used, the variety of pesticides used and pesticide application frequency. The direct implications are the benefit to farmers in improving mango quality and maximizing profit per yield cycle.

Research limitations/implications

To the best of the authors’ knowledge, the first research that has specifically focused on holistically improving the quality(size) of mangoes.

Originality/value

The findings contribute to the perishable supply chain literature, specifically to the mango study, to comprehensively showcase the factors impacting the quality of mangoes and provide guidance to farmers regarding orchard practices.

Abstract

Purpose

This study aims to highlight the inconsistency between conventional knowledge push judgements and the price of knowledge push. Also, a three-way decision-based relevant knowledge push algorithm was proposed.

Design/methodology/approach

Using a ratio of 80–20%, the experiment randomly splits the data into a training set and a test set. Each video is used as a knowledge unit (structure) in the research, and the category is used as a knowledge attribute. The limit is then determined using the user’s overall rating. To calculate the pertinent information obtained through experiments, the fusion coefficient is needed. The impact of the push model is then examined in comparison to the conventional push model. In the experiment, relevant knowledge is compared using three push models, two push models based on conventional International classification functioning (ICF), and three push models based on traditional ICF. The average push cost accuracy rate, recall rate and coverage rate are metrics used to assess the push effect.

Findings

The three-way knowledge push models perform better on average than the other push models in this research in terms of push cost, accuracy rate and recall rate. However, the three-way knowledge push models suggested in this study have a lower coverage rate than the two-way push model. So three-way knowledge push models condense the knowledge push and forfeit a particular coverage rate. As a result, improving knowledge results in higher accuracy rates and lower push costs.

Practical implications

This research has practical ramifications for the quick expansion of knowledge and its hegemonic status in value creation as the main methodology for knowledge services.

Originality/value

To the best of the authors’ knowledge, this is the first theory developed on the three-way decision-making process of knowledge push services to increase organizational effectiveness and efficiency.

Abstract

Purpose

This study traced the architectural, urban and social characteristics of the Bugok Railway Official Residences (BRORs) in South Korea. It also explored the modern elements of Western (or Japanized Western) or traditional Korean characteristics embodied in the BRORs in the modernization process of Korea in the early 20th century.

Design/methodology/approach

Through literature reviews, field trips and archive investigation, this study uncovered new critical facts concerning the origin of the BRORs’ construction plan and architectural characteristics.

Findings

The BRORs’ value can be described as follows. First, the BRORs are the first modern housing complex in the Uiwang region. Second, they are meaningful as a housing area built during the Japanese colonial period, and many houses were concentrated in the center of a large city. Third, each official residence shows that various phenomena (mass production, standardization, efficiency and so on) are concentrated in buildings from premodern to modern period. Finally, the image of a group residential complex about to be demolished due to redevelopment is recorded in detail.

Social implications

In the 1940s, the Railway Bureau of the Japanese Government-General of Korea planned a new small-scale town where mainly railway workers would live. The BRORs in Sam-dong, Uiwang were the first-phase plan. Specifically, 200 households in 100 buildings (two households per building) were built in 1943 during the end of the Japanese colonial period. After the liberation in 1945, these residences were made available to the general public and only 27 households remained through modification and renovation. The remaining residences will be demolished in 2023.

Originality/value

This research examined the meaning of the BRORs, which had not previously been researched in-depth, from diverse perspectives; accordingly, the basic research required for sustainable archiving can be performed after demolition using the study data.

Abstract

Purpose

Given the distinct and unique climates in these countries, research conducted in other parts of the world may not be directly applicable. Therefore, it is crucial to conduct research tailored to the specific climatic conditions of Australia and New Zealand to ensure accuracy and relevance.

Design/methodology/approach

Given population growth, urban expansions and predicted climate change, researchers should provide a deeper understanding of microclimatic conditions and outdoor thermal comfort in Australia and New Zealand. The study’s objectives can be classified into three categories: (1) to analyze previous research works on urban microclimate and outdoor thermal comfort in Australia and New Zealand; (2) to highlight the gaps in urban microclimate studies and (3) to provide a summary of recommendations for the neglected but critical aspects of urban microclimate.

Findings

The findings of this study indicate that, despite the various climate challenges in these countries, there has been limited investigation. According to the selected papers, Melbourne has the highest number of microclimatic studies among various cities. It is a significant area for past researchers to examine people’s thermal perceptions in residential areas during the summer through field measurements and surveys. An obvious gap in previous research is investigating the impacts of various urban contexts on microclimatic conditions through software simulations over the course of a year and considering the predicted future climate changes in these countries.

Originality/value

This paper aims to review existing studies in these countries, provide a foundation for future research, identify research gaps and highlight areas requiring further investigation.

Abstract

Purpose

The pandemic presented many new challenges is all spheres of life including faith communities. Around the globe, lockdowns took pace at various stages with varying restrictions that included the closure of places of worship which significantly affected the way people serve God and gather as a community. The purpose of this study was to investigate the impact of the Covid-19 pandemic on the wellbeing and resilience of members of Christian faith communities in Melbourne (Australia) who had experienced one of the longest lockdowns in the world.

Design/methodology/approach

The authors draw on online survey N = 106 collected between November 2021 and May 2021. Participants were over the age of 18 from Catholic, Anglican, Uniting Church, Baptist and Pentecostal/Evangelical faith communities. They employ thematic analysis to analyze, and code open-ended responses from four questions in relation to the research question: In what ways has your wellbeing been impacted during the pandemic?

Findings

Melbourne experienced one of the longest lockdown periods in the world between 2020 and 2021 when blended modes of worship forced people to congregate in new and different ways. The empirical insights of participants express their views in relation to celebrating faith and hope, connecting with community, pursuing leisure activities and pursuing leisure in relation to the PERMA model of wellbeing. The findings may resonate with other faith communities in Melbourne and around the globe. They may also lead to new and innovative ways of planning and envisioning modes of worship that may be helpful in a variety of faith contexts.

Research limitations/implications

The research was limited by its sample size (N = 106) and its geographical restriction of Christian faith communities in the Melbourne metropolitan area. This means that broad generalizations cannot be made. Nevertheless, the findings may resonate with other faith communities in Australian and in other parts of the world.

Practical implications

In highlighting the impact COVID-19 had in Australia and ways people balanced their sense of faith and wellbeing, this study raises concerns about the lack of funding that supports mental health initiatives in faith settings and the wider community. The study recommends that faith community leaders and members use informal communication channels to foster hope building wellbeing and resilience, and that pastoral care networks be established in the wider community to promote leisure activities that nurtures social connection, builds faith and resilience.

Social implications

Whilst the pandemic has provided new openings for members of faith communities to engage with God, the scriptures, each other and leisure, it remains “a balancing act of keeping the faith and maintaining wellbeing”. Such a balancing act may positively enliven a sense of wellbeing and resilience as people continue to navigate the uncertainty inherent in a milieu beginning to be named as “post-Covid”.

Originality/value

This is an original work carried out by the authors. It raises concerns about the lack of funding that supports mental health initiatives in faith settings and the wider community. While much research, news and social media discussed the pandemic's impact on communities, there is an urgent need for ongoing research that encourages, supports and connects people to faith and to leisure activities in order to promote a continued sense of wellbeing as communities begin to transition to a “post-Covid” world. This study contributes to the growing body of knowledge about the impact COVID-19 had in Australia and ways people balanced their sense of faith and wellbeing.
