Abstract
Purpose
The objective of this work was to develop practical experimental techniques for monitoring corrosion in “difficult‐to‐test” conditions such as corrosion under insulation (CUI).
Design/methodology/approach
An electrochemically integrated multi‐electrode array namely the wire beam electrode (WBE) method has been used in combination with noise signature analysis for the first time to monitor the penetration of corrosive species under simulated corrosion‐under‐insulation conditions. Corrosion of aluminium exposed under insulation materials such as rock wool, glass wool, cotton wool and tissue paper has been successfully monitored.
Findings
A typical potential noise signature of a major potential jump from AA1100 WBE was observed which corresponded to the corrosive species reaching the WBE surface in WBE current distribution map. A good correlation between the galvanic current maps and the corroded surface was also observed.
Originality/value
The preliminary results suggest that the proposed novel electrochemical method is capable of monitoring CUI.

Abstract
Purpose
Climate change is an undeniable reality that threatens people’s livelihoods. Flooding and saltwater intrusion, along with the rising sea levels, are affecting agricultural and aquaculture livelihoods in Myanmar’s coastal areas. Although climate change adaptation is gaining popularity as a resilience strategy to cope with the negative effects of climate change, both agriculture- and aquaculture-farmers are more often deterred from implementing climate change adaptation strategies due to practical availability and socioeconomic barriers to adaptation. This study aims to evaluate the barriers and factors that influence farm household’ choice of climate change adaptation measures.
Design/methodology/approach
This study was conducted with 599 farm households (484 rice-farmers and 115 fish farmers) based in the coastal areas of Myanmar during 2021–2022 to explore the farmer’s choice of climate change adaptation measures and the determining factors. The multinomial logit regression (MLR) model was used to examine the factors influencing the farmers’ choice of climate change adaptation strategies.
Findings
The study found out that farm households use a variety of adaptation methods at the farm level, with building embankment strategy (23.4%) in agriculture and net-fencing measure (33.9%) in fish farming being the most popular adaptation strategies. Farmers’ decisions to adopt climate change adaptation strategies are influenced by factors such as distance to market, education level of the household head, remittance income and the availability of early warning information, among others. The study also discovered that COVID-19 has had an impact on the employment opportunities of household members and the income from farming as well had a consequential effect on the adoption of climate change adaptation measures. Furthermore, lack of credit (42.4%), labor shortage (52.8%), pest and disease infestation (58.9%), high input costs (81%) and lower agricultural product prices (73%) were identified as major barriers to the adoption of climate change adaptation measures by both agriculture and aquaculture farm households.
Originality/value
This study demonstrates that the COVID-19 pandemic and farm-level barriers are the major factors influencing farm households’ choice of climate change adaptation measures, and that removing practical farm-level barriers and encouraging the adoption of adaptation techniques as potential COVID-19 recovery actions are required. This study also highlighted that the adaptive capacity of agriculture and aquaculture farm households should be strengthened through formal and informal training programs, awareness raising, the exchange of early warning information and the development of proper credit scheme programs.

Abstract
Purpose
The purpose of this paper is to focus on the removal of copper(II) ions from aqueous model salt solution by using chitosan-coated magnetite nanoparticles.
Design/methodology/approach
The chitosan-coated magnetite nanoparticles were characterized using X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy and thermogravimetric differential thermal analysis. The adsorption of Cu(II) by using magnetite nanoparticles as an adsorbent was investigated under different adsorption conditions. The parameters studied were contact time, adsorbent dose and initial concentrations.
Findings
The sorption capacities of prepared samples were studied for the removal of Cu2+ ions from aqueous model solutions with varying experimental conditions of the initial metal concentration, contact time and dosage. It is found that the removal percent of Cu2+ ions increases with an increase in initial metal concentration, contact time and amount of dosage.
Originality/value
Based on the obtained results, this study recommends that chitosan-coated magnetite nanoparticles can also be applied for removal of some heavy metal ions and/or organic compounds in aqueous solution. It is recommended that this study be shared with the polymer-based nanomaterial researchers, especially material science.

Abstract
Purpose
Malaria still remains a significant public health problem in Myanmar and it has a complex epidemiology. Evidence-based community awareness raising interventions are also particularly needed. This cross-sectional study was organized to explore the basic characteristics associated with knowledge, attitude and practice (KAP) regarding malaria among people living in the most malaria-endemic villages of the Banmauk Township, Sagaing Region, Myanmar. The paper aims to discuss these issues.
Design/methodology/approach
The Banmauk, one of the most malaria-endemic townships, was selected purposively in order to represent the survey results for people living in malaria hotspots. During the peak malaria season (July 2018), 250 household leaders were invited to be interviewed with structured questionnaires. In addition to descriptive data, the associations were determined by χ2-test and correlation.
Findings
Overall KAP indicated considerably low percentages of good levels, especially in practice, only 21.6 percent showed good practice, 38.4 percent had good knowledge and 56.8 percent had good attitude. Age (p=0.022) and annual family income (p<0.001) were significantly associated with the knowledge level, whereas having fever attacks among family members in the last two weeks (p=0.023) showed statistical association with attitude at a p-value <0.05. Surprisingly, there were no associated variables with malaria practice. In addition, there were negative correlations between knowledge with attitude and knowledge with practice; however, the results were not significant.
Originality/value
The overall KAP regarding malaria was at relatively poor levels among people living in malaria transmission areas. Therefore, new approaches to improve malaria KAP are promptly needed in this community.

Abstract
Purpose
This study aims to investigate the health-care-seeking behaviour and practices of West African migrants who reside and operate in Wa, Ghana, as itinerant retailers.
Design/methodology/approach
The study was cross-sectional and used the quantitative research approach. The analysis was done on a target population comprising 122 itinerant immigrant retail traders in Wa, Ghana. Fisher’s exact test and logistic regression were used to analyse the data.
Findings
Malaria was the commonest disease among them. Five in ten of the migrants preferred to report malaria episodes to a private health facility than to a government facility. Significant associations were identified between four dimensions (health facility, self-medication, home remedy and consult others) of health-seeking behaviour, and some background characteristics. The main reason why migrants prefer government health facilities was because of their better health personnel. They self-medicated because of easy accessibility of over-the-counter medicine shops. Also, when ill, the migrants usually consulted family members who would be in a position to take them home when their ailment worsens.
Research limitations/implications
Snowball sampling was used to select the respondents which could potentially lead to a sample that is not fully representative of the population in general.
Originality/value
Studies concerning migration and health in Ghana have been focused on internal migrants. Yet, minority immigrant traders equally encounter adverse health conditions but limited studies have been conducted to espouse their health-seeking behaviour. This study imperatively contributes to the subject matter that has limited literature in the country.

Abstract
Purpose
The purpose of this paper is to highlight the cultural issues and difficulties encountered when conducting ethnographic fieldwork and interviews in Myanmar and to discuss the measures to overcome such challenges. It aims to provide insight for foreign researchers seeking to collect rich, meaningful and reliable data while establishing fruitful relationship with Burmese participants.
Design/methodology/approach
This paper draws on results from a research on cross-cultural dispute resolution in a Chinese-invested enterprise in Myanmar. The authors reflect on their fieldwork experience to present examples of cultural challenges, as well as the strategies used to deal with those challenges.
Findings
This paper finds that when conducting ethnographic fieldwork and interviews in Myanmar, researchers should take into consideration “anade” – an important Burmese social convention, perceived power distance between researchers and Burmese participants, roles of cross-cultural interpreters and possibility of cultural stereotypes, especially in a multicultural site. Measures need to be taken to adjust fieldwork arrangement and interview style, reduce perceived power distance and address the impact of prevalent stereotypes. Furthermore, researchers should properly conduct training and discussion sessions with Burmese interpreters to ensure they provide accurate yet culturally informed interpretation.
Originality/value
The cultural challenges in conducting ethnographic fieldwork and interviews in Myanmar remain under-explored. This paper addresses the knowledge gap and discusses various Myanmar-specific cultural issues that await researchers.

Abstract
Agricultural and food systems in the Mekong Region are undergoing transformations because of increasing engagement in international trade, alongside economic growth, dietary change and urbanisation. Food systems approaches are often used to understand these kinds of transformation processes, with particular strengths in linking social, economic and environmental dimensions of food at multiple scales. We argue that while the food systems approach strives to provide a comprehensive understanding of food production, consumption and environmental drivers, it is less well equipped to shed light on the role of actors, knowledge and power in transformation processes and on the divergent impacts and outcomes of these processes for different actors. We suggest that an approach that uses food systems as heuristics but complements it with attention to actors, knowledge and power improves our understanding of transformations such as those underway in the Mekong Region. The key transformations in the region include the emergence of regional food markets and vertically integrated supply chains that control increasing share of the market, increase in contract farming particularly in the peripheries of the region, replacement of crops cultivated for human consumption with corn grown for animal feed. These transformations are increasingly marginalising small-scale farmers, while at the same time, many other farmers increasingly pursue non-agricultural livelihoods. Food consumption is also changing, with integrated supply chains controlling substantial part of the mass market. Our analysis highlights that theoretical innovations grounded in political economy, agrarian change, development studies and rural livelihoods can help to increase theoretical depth of inquiries to accommodate the increasingly global dimensions of food. As a result, we map out a future research agenda to unpack the dynamic food system interactions and to unveil the social, economic and environmental impacts of these rapid transformations. We identify policy and managerial implications coupled with sustainable pathways for change.

Abstract
The purpose of this research is to explore the views of individuals responsible for quality assurance in Hong Kong (HK) food and beverage companies with regards to their acceptance or rejection of the ISO 9000 quality management system or HACCP food safety system standards, along with the reasoning underlying such views. Thirty Hong Kong food or beverage manufacturing companies were approached and in‐depth interviews in the form of surveys were conducted with 11 companies. Participating companies included companies that had implemented both the ISO 9000 and HACCP standards, companies that had implemented only ISO 9000 or HACCP, and a company that had implemented neither. Half of the companies that participated in this study were large companies with 500 or more employees. The use of ISO 9000 was reported to improve the maturity of other quality systems. The use of HACCP was reported to improve the maturity of other food safety systems. While more companies used HACCP than the ISO 9000 standard to comply with customers’ requirements, the difficulties in the training of staff and added costs for documentation/data storage were reported as common to both standards.
