Abstract

Purpose

This study aims to construct an evaluation system for farmers’ livelihood capital in minority areas and evaluate the impact of relocation in response to climate change on farmers’ livelihood capital.

Design/methodology/approach

According to the characteristics of Yunnan minority areas, the livelihood capital of farmers in minority areas is divided into natural, physical, financial, social, human and cultural capital. The improved livelihood capital evaluation system measures farmers’ livelihood capital from 2015 to 2021. The net impact of relocation on farmers’ livelihood capital was separated using propensity score matching and the difference-in-difference (PSM-DID) method.

Findings

The shortage of livelihood capital makes it difficult for farmers to resist climate change, and the negative impacts of climate change further aggravate their livelihood vulnerability and reduce their livelihood capital. Relocation has dramatically increased the livelihood capital of farmers living in areas with poor natural conditions by 15.67% and has enhanced their ability to cope with climate change and realise sustainable livelihoods.

Originality/value

An improved livelihood capital evaluation system is constructed to realise the future localisation and development of livelihood capital research. The PSM-DID method was used to overcome endogeneity problems and sample selection bias of the policy evaluation methods. This study provides new ideas for academic research and policy formulation by integrating climate change, poverty governance and sustainable livelihoods.

Abstract

Purpose

The paper's purpose is to investigate the effects of digital finance on the risk of stock price crashes and the underlying transmission mechanisms, and to provide suggestions to inhibit the stock crash risk (CR).

Design/methodology/approach

This paper selects all companies that were listed on the Shanghai Stock Exchange and the Shenzhen Stock Exchange from 2011 to 2020. It then uses the two-way fixed effect model and the intermediary effect model to verify such effects.

Findings

The overall outcomes demonstrate such a result that the CR of listed companies in China can be significantly reduced by the development of digital finance, and the overall transparency of business financial information and the equity pledge of controlling shareholders are the two underlying transmission mechanisms that digital finance can cause effects on the CR of stocks.

Research limitations/implications

The main limitations are that there may exist some problems in the method for evaluating the CR of stocks. And there may be a problem of endogeneity caused by the empirical model cannot control all correlation variables.

Practical implications

This paper would provide policy implications, for different roles, to inhibit the stock CR and to make the development of the economy more stabilize.

Social implications

Digital finance can promote economic development while restraining financial risks at the same time. Therefore, although this study is based on the relevant data from China, it can also provide a reference for other economies with different basic conditions from China, to promote the overall development of the world economy.

Originality/value

The current academic research on digital finance or stock price CR has been relatively sufficient, but there are few papers that combined both. By combining digital finance with stock CR, this paper researches the influence of digital finance on the CR of stocks through empirical analysis. So, this paper would provide new research ideas and evidence for potential influence factors of the CR of stocks, fill the gap in this research field and provide certain help for subsequent scholars to conduct relevant research.

Abstract

Purpose

Epoxy zinc-rich coatings are widely used in harsh environments because of the long-lasting cathodic protection of steel surfaces. The purpose of this paper is to use flake zinc powder instead of the commonly used spherical zinc powder to reduce the zinc powder content.

Design/methodology/approach

In this paper, the authors have prepared an anticorrosive zinc-rich coating using a flake zinc powder instead of the conventional spherical zinc powder. The optimal dispersion of scaly zinc powder in zinc-rich coatings has been explored by looking at the surface and cross-sectional morphology and studying the cathodic protection time of the coating.

Findings

The final epoxy zinc-rich coating with 35 Wt.% flake zinc powder content was prepared using sand-milling dispersions. It has a similar cathodic protection time and salt spray resistance as the 60 Wt.% spherical zinc-rich coating, with a higher low-frequency impedance modulus value.

Originality/value

This study uses flake zinc powder instead of the traditional spherical zinc powder. This reduces the amount of zinc powder in the coating and improves the corrosion resistance of the coating.

This paper aims to explore how experienced nurses relate to hazing and uncover the underlying limits of tolerance for newcomers.

Abstract

Purpose

This paper aims to explore how experienced nurses relate to hazing and uncover the underlying limits of tolerance for newcomers.

Design/methodology/approach

Data were collected through eight qualitative focus group interviews (n = 35) and analysed using reflexive thematic coding.

Findings

The analysis revealed three themes in the limits of experienced nurses’ tolerance of newcomers: “Don’t be sensitive”, “Prove your respectability” and “Accept your inequality of rights”.

Originality/value

The paper challenges existing perspectives on hazing motivation since tolerating newcomers is motivated by defending the status quo against threatening and challenging newcomers.

Abstract

Purpose

This research explored the storytelling (collection, curation and use) in the Cabrach, a remote Scottish glen. This study aims to capture the methodological process of storytelling and curation of heritage knowledge through the lens of the Cabrach's whisky distilling history, a central part of the area's cultural heritage, tangible and intangible. This research was conceptualised as “telling the story of telling the story of the Cabrach”. It was concerned with how the history, heritage, historiography and testimony associated with the parish could be harvested, made sense of and subsequently used.

Design/methodology/approach

The study was epistemological in nature and the research was concerned with how heritage knowledge is gathered, curated and understood. It was built around the collection of knowledge through expert testimony from Colin Mackenzie and Alan Winchester, who have extensively researched aspects of life in the Cabrach. This was done using a series of theme-based but free-flowing conversational workshop involving participants and research team. Issues of trust and authority in the research team were crucial. Data were recorded, transcribed and coded. A conceptual model for heritage storytelling in the Cabrach was developed together with a transferable version for other contexts.

Findings

The research was conceived around identifying the stories of the Cabrach and grouping them into cohesive narrative themes focused on the most important aspect of the glen's history (the development of malt whisky distilling). The research showed how all crucial narratives associated with the Cabrach were interconnected with that malt whisky story. It was concerned with identifying broad thematic narratives rather than the specific detailed stories themselves, but also from a methodological perspective how stories around those themes could be collected, curated and used. It presents the outcome of “expert testimony” oral history conversations and presents a conceptual model for the curation of heritage knowledge.

Practical implications

This paper reports on research which focuses on the confluence of those issues of heritage-led regeneration, intangible cultural heritage, as well as how stories of and from, about and for, a distinctive community in North-East Scotland can be collected, curated and displayed. It presents methodological conceptualisations as well as focused areas of results which can be used to create a strong and inclusive narrative to encapsulate the durable sense of place and support the revival of an economically viable and sustainable community.

Social implications

This conceptual model offers a framework with universal elements (Place, People, Perception) alongside a strong core narrative of storytelling. That core element may vary but the outer elements remain the same, with people and place being omnipresent and the need to build an emotional or visceral connection with visitors being crucial, beyond “telling stories” which might be regarded as parochial or narrowly focused. The model informs how communities and heritage organisations tell their stories in an authentic and proportionate manner. This can help shape and explain cultures and identities and support visitors' understanding of, and connection with, places they visit and experience.

Originality/value

The originality lies in two principal areas, the exploration of the narratives of a singularly distinctive community – the Cabrach – which plays a disproportionately significant role in the development of malt whisky distilling in Scotland; and also in terms of the methodological approach to the collection and curation of heritage storytelling, drawing not on first-hand accounts as in conventional oral history approaches but through the expert testimony of two historical and ethnographic researchers. The value is demonstrating the creation of a conceptual model which can be transferred to other contexts.

Abstract

Purpose

This study aims to understand consumers' reactions to hospitality corporate social responsibility (CSR) campaigns under different resource scarcity reminders, an important but overlooked contextual factor, and examine how such scarcity reminders interact with message framing, a widely used technique in CSR communication.

Design/methodology/approach

Three experimental studies were conducted. Studies 1 and 2 examined the main effect of resource scarcity reminders (environmental vs personal) on consumer engagement via self-other orientation. Study 3 further investigated the interactive effect between resource scarcity reminders (environmental vs personal) and message framing (gain vs loss) with hope as a key mediator.

Findings

Studies 1 and 2 show that environmental (vs personal) scarcity activates a more salient other orientation, subsequently increasing consumers' donation and word-of-mouth intentions. Study 3 reveals that environmental (vs personal) scarcity makes people more hopeful with gain-framed messages. Moreover, the elevated hope enhances perceived efficacy (attitude toward the company), leading to higher donation (word-of-mouth) intention.

Practical implications

Hospitality marketers could remind consumers of the harsh environment to elicit other orientation and encourage CSR participation. Using gain-framed messages or other hope-inducing appeals would be particularly advantageous in engaging consumers in CSR campaigns during heightened environmental scarcity.

Originality/value

Focusing on consumer responses to CSR campaigns, to the best of the authors’ knowledge, this research is the first to reveal reminders of resource scarcity as a novel antecedent factor and further uncover how such reminders interact with message framing to affect CSR engagement.

Abstract

Purpose

Pipelines are subject to pits, holes and cracks after staying in service for a while, especially in harsh environments. To repair the pipelines, composite materials are used, due to composite materials' low cost, high-corrosion resistance and easy handling. This study aims to investigate the reliability of the blister test for evaluating the bonding strength of multiwall carbon nanotube (MWCNT) on woven carbon-reinforced epoxy.

Design/methodology/approach

Flexural, hardness and Izod impact tests were used to evaluate MWCNT effect on the epoxy by adding different amounts, 0.2, 0.4, 0.6, 0.8 and 1 wt. %, of MWCNT, to be compared with pure epoxy.

Findings

The results showed that 0.8 wt.% gives the highest strength. The experimental results of 0.8 wt.% MWCNT reinforced carbon composite was compared with the finite element model under blister test, and the results showed high similarities.

Originality/value

Evaluation of the reliability and the advantages of MWCNT considering the high aspect ratio and high tensile strength, which is more than 15 times compared to steel, MWCNT enhances the strength, stiffness and toughness of epoxy used as a matrix in repairing pipelines, which leads to an increase in the resistance of composite materials against oil internal pressure before delamination.

Abstract

Purpose

This paper aims to investigate the moisture diffusion behavior in a system-in-package module systematically by moisture-thermalmechanical-coupled finite element modeling with different structure parameters under increasingly harsh environment.

Design/methodology/approach

A finite element model for a system-in-package module was built with moisture-thermal-mechanical-coupled effects to study the subsequences of hygrothermal conditions.

Findings

It was found in this paper that the moisture diffusion path was mainly dominated by hygrothermal conditions, though structure parameters can affect the moisture distribution. At lower temperatures (30°C~85°C), the direction of moisture diffusion was from the periphery to the center of the module, which was commonly found in simulations and literatures. However, at relatively higher temperatures (125°C~220°C), the diffusion was from printed circuit board (PCB) to EMC due to the concentration gradient from PCB to EMC across the EMC/PCB interface. It was also found that there exists a critical thickness for EMC and PCB during the moisture diffusion. When the thickness of EMC or PCB increased to a certain value, the diffusion of moisture reached a stable state, and the concentration on the die surface in the packaging module hardly changed. A quantified correlation between the moisture diffusion coefficient and the critical thickness was then proposed for structure parameter optimization in the design of system-in-package module.

Originality/value

The different moisture diffusion behaviors at low and high temperatures have seldom been reported before. This work can facilitate the understanding of moisture diffusion within a package and offer some methods about minimizing its effect by design optimization.

Abstract

Purpose

Stainless-clad bimetallic steels (SCBS) are widely investigated in some extremely environmental applications areas, such as polar sailing area and tropical oil and gas platforms areas, because of their excellent anticorrosion performance and relatively lower production costs. However, the properties of SCBS, including the mechanical strength, weldability and the anticorrosion behavior, have a direct relation with the manufacturing process and can affect their practical applications. This paper aims to review the application and the properties requirements of SCBS in marine environments to promote the application of this new material in more fields.

Design/methodology/approach

In this paper, the manufacturing process, welding and corrosion-resistant properties of SCBS were introduced systematically by reviewing the related literatures, and some results of the authors’ research group were also introduced briefly.

Findings

Different preparation methods, such as rolling composite, casting rolling composite, explosive composite, laser cladding and plasma arc cladding, as well as the process parameters, including the vacuum degree, rolling temperature, rolling reduction ratio, volume ratios of liquid to solid, explosive ratio and the heat treatment, influenced a lot on the properties of the SCBS through changing the interface microstructures. Otherwise, the variations in rolling temperature, pass, reduction and the grain size of clad steel also brought the dissimilarities of the mechanical properties, microhardness, bonding strength and toughness. Another two new processes, clad teeming method and interlayer explosive welding, deserve more attention because of their excellent microstructure control ability. The superior corrosion resistance of SCBS can alleviate the corrosion problem in the marine environment and prolong the service life of the equipment, but the phenomenon of galvanic corrosion should be noted as much as possible. The high dilution rate, welding process specifications and heat treatment can weaken the intergranular corrosion resistance in the weld area.

Originality/value

This paper summarizes the application of SCBS in marine environments and provides an overview and reference for the research of stainless-clad bimetallic steel.

Abstract

Purpose

This paper aims to conduct a detailed analysis of the industrial practices currently being used in the geothermal energy industry and to determine whether they are contributing to any limitations. A HAZOP-based upgradation model for improvement in existing industrial practices is proposed to ensure the removal of inefficient conventional practices. The HAZOP-based upgradation model examines the setbacks, identifies its causes and consequences and suggests improvement methods comprising of modern-day technology.

Design/methodology/approach

This paper proposed a HAZOP-based upgradation model for improvement in existing industrial practices. The proposed HAZOP model identifies the drawbacks brought on by conventional practices and suggests improvements.

Findings

The study reviewed the challenges geothermal power plants currently face due to conventional practices and suggested a total of 22 upgradation recommendations. From those, a total of 11 upgradation modules comprising modern digital technology and Industry 4.0 elements were proposed to improve the existing practices in the geothermal energy industry. Autonomous robots, augmented reality, machine learning and Internet of Things were identified as useful methods for the upgradation of the existing geothermal energy system.

Research limitations/implications

If proposed recommendations are incorporated, the efficiency of geothermal energy generation will increase as cumulating setbacks will no longer degrade the work output.

Practical implications

The proposed recommendation by the study will make way for Industry 4.0 integration with the geothermal energy sector.

Originality/value

The paper uses a proposed HAZOP-based upgradation model to review issues in existing industrial practices of the geothermal energy sector and recommends solutions to overcome operability issues using Industry 4.0 technologies.
