The purpose of this study is to investigate cathodic protection (CP) efficiency in the tidal zone and its associated processes.

Abstract

Purpose

The purpose of this study is to investigate cathodic protection (CP) efficiency in the tidal zone and its associated processes.

Design/methodology/approach

Specific features of CP in the tidal zone, that is, persistence of a thin seawater film and insufficient cathodic potential due to ohmic drop, were addressed. In this preliminary study, carbon steel electrodes were polarized at two cathodic potentials (correct or insufficient protection) while immersed in 1 mm or 5 mm thick natural seawater layers. After CP interruption, the protective ability of the layers covering the steel electrodes was studied using various electrochemical methods, including electrochemical impedance spectroscopy. The layers were characterized by XRD.

Findings

The protective ability of calcareous deposits was increased in thin seawater films. Insufficient CP could promote protective aragonite/corrosion products layer.

Originality/value

The combined effects of thin seawater film and applied potential were never addressed, and the conclusions drawn from this preliminary study give new insight on the efficiency of CP in the tidal zone.

Abstract

The author presents new estimates of the probability weighting functions found in rank-dependent theories of choice under risk. These estimates are unusual in two senses. First, they are free of functional form assumptions about both utility and weighting functions, and they are entirely based on binary discrete choices and not on matching or valuation tasks, though they depend on assumptions concerning the nature of probabilistic choice under risk. Second, estimated weighting functions contradict widely held priors of an inverse-s shape with fixed point well in the interior of the (0,1) interval: Instead the author usually finds populations dominated by “optimists” who uniformly overweight best outcomes in risky options. The choice pairs used here mostly do not provoke similarity-based simplifications. In a third experiment, the author shows that the presence of choice pairs that provoke similarity-based computational shortcuts does indeed flatten estimated probability weighting functions.

Abstract

Purpose

Owing to highly volatile and chaotic external events, predicting future movements of cryptocurrencies is a challenging task. This paper advances a granular hybrid predictive modeling framework for predicting the future figures of Bitcoin (BTC), Litecoin (LTC), Ethereum (ETH), Stellar (XLM) and Tether (USDT) during normal and pandemic regimes.

Design/methodology/approach

Initially, the major temporal characteristics of the price series are examined. In the second stage, ensemble empirical mode decomposition (EEMD) and maximal overlap discrete wavelet transformation (MODWT) are used to decompose the original time series into two distinct sets of granular subseries. In the third stage, long- and short-term memory network (LSTM) and extreme gradient boosting (XGB) are applied to the decomposed subseries to estimate the initial forecasts. Lastly, sequential quadratic programming (SQP) is used to fetch the forecast by combining the initial forecasts.

Findings

Rigorous performance assessment and the outcome of the Diebold-Mariano’s pairwise statistical test demonstrate the efficacy of the suggested predictive framework. The framework yields commendable predictive performance during the COVID-19 pandemic timeline explicitly as well. Future trends of BTC and ETH are found to be relatively easier to predict, while USDT is relatively difficult to predict.

Originality/value

The robustness of the proposed framework can be leveraged for practical trading and managing investment in crypto market. Empirical properties of the temporal dynamics of chosen cryptocurrencies provide deeper insights.

Abstract

Purpose

This study aimed to identify and describe how mentoring influences the mentor, by operationalising and specifying learning outcomes involved in mentoring.

Design/methodology/approach

This study used an action research approach, by uniting theory and practice to explore new ways of learning and evolve the field of practice in education. Thematic analysis was used to identify and organise patterns or themes that emerged from the data.

Findings

The results showed that mentoring changed the mentors' perspectives towards improved understanding, more flexibility and approval of other cultures. It seems that mentoring expanded the mentors' search for values, wishes and resources, including an awareness that our values, wishes and needs are more similar than different. Mentoring also seems to have improved the ability to reformulate, be flexible, strive to optimise user engagement and engage with people as they are, based on their own prerequisites.

Research limitations/implications

The low number of participants means the results cannot be generalised, and voluntary participation may have led to more motivated involvement and positive results.

Practical implications

This study shows that mentoring has had an impact on students' development of intercultural competence and cultural sensitivity through regular meetings with individuals from a different cultural background. Mentoring seems to have revealed insights into underlying prejudices and changed perspectives towards better understanding, thus increased acceptance of other cultures.

Originality/value

Search for similar studies shows a lack of research that operationalises and specifies the learning outcomes that mentors gain from being a mentor.

Abstract

Purpose

The purpose of this study is to explore the potential for technical accounting resources to help professional accountants exercise their performative agency.

Design/methodology/approach

The authors combine the integrative learning theory of truth and the concept of performativity, including two approaches to sustainability education and interventions, to construct a grid for coding the technical resources provided by the UK's Institute of Chartered Accountants in England and Wales, a pioneer in sustainability advocacy.

Findings

The findings suggest the dominance of the “predetermined and expert-determined” approach. They also reveal the emergence of three levels of performative topoi based on the relative presence of the “predetermined and expert-determined” and “process-of-seeking” approaches to professional interventions toward sustainability. The results show the profession's evolving contribution to the construction of actionable knowledge.

Research limitations/implications

The main limitation of this research is that it draws on a limited corpus. In addition, the use of a binary code to represent the presence/absence of a code does not convey the code's quantitative importance.

Practical implications

The results are useful for those wanting to produce technical accounting resources that are more likely to help professionals build actionable knowledge and contribute to accountants' interventions toward sustainability.

Social implications

Findings suggest the need for reflection on how the accounting profession can best contribute to implementing sustainability in organizations.

Originality/value

Few studies deconstruct professional technical resources to see how a profession can contribute to a process of societal change.

Abstract

Purpose

Despite large bodies of research related to the impacts of e-commerce on last-mile logistics and sustainability, there has been limited effort to evaluate urban freight using an equity lens. Therefore, this study proposes a modeling framework that enables researchers and planners to estimate the baseline equity performance of a major e-commerce platform and evaluate equity impacts of possible urban freight management strategies. The study also analyzes the sensitivity of various operational decisions to mitigate bias in the analysis.

Design/methodology/approach

The model adapts empirical methodologies from activity-based modeling, transport equity evaluation, and residential freight trip generation (RFTG) to estimate person- and household-level delivery demand and cargo van traffic exposure in 41 U.S. Metropolitan Statistical Areas (MSAs).

Findings

Evaluating 12 measurements across varying population segments and spatial units, the study finds robust evidence for racial and socio-economic inequities in last-mile delivery for low-income and, especially, populations of color (POC). By the most conservative measurement, POC are exposed to roughly 35% more cargo van traffic than white populations on average, despite ordering less than half as many packages. The study explores the model’s utility by evaluating a simple scenario that finds marginal equity gains for urban freight management strategies that prioritize line-haul efficiency improvements over those improving intra-neighborhood circulations.

Originality/value

Presents a first effort in building a modeling framework for more equitable decision-making in last-mile delivery operations and broader city planning.

Abstract

Introduction: Small- and medium-sized enterprises (SMEs) play a vital role in the economic development of economies by generating job opportunities. Considering their significance, understanding the challenges and skills required in these enterprises becomes essential and timely.

Purpose: This study aims to discuss the limitations and skill gaps faced by SMEs in emerging economies, such as India, Indonesia, Brazil, China, Malaysia, Ghana, Hungary, Saudi Arabia, South Africa, Türkiye, UAE, Iran, Kazakhstan, Türkiye, Zambia, Romania, and Vietnam.

Methodology: The study adopts a systematic review and meta-synthesis approach, utilising a literature review to comprehensively analyse, synthesise, and map the existing literature by identifying overarching themes.

Findings: The study examines the challenges SMEs encounter in emerging economies, including resource scarcity, limited access to credit, inadequate infrastructure, low technology adoption, restricted global market access, and ineffective marketing strategies. There is a notable shortage of skilled labour and development initiatives within SMEs in India even though the country has a sizeable pool of qualified workers. There is a pressing need for additional technical and managerial skills to remain competitive in the market. The findings of this study will assist HR managers in addressing skill shortages among employees in SMEs operating within emerging economies

Abstract

Purpose

Refugees and asylum seekers worldwide face numerous barriers in accessing health systems. The evidence base regarding who and what helps refugees and asylum seekers facilitate access to and the navigation of the health system in the UK is small. This study aims to address this gap by analysing 14 semi-structured, in-depth interviews with refugees and asylum seekers of different countries of origin in the UK to identify where, when and how they came into contact with the health-care system and what the outcome of these interactions was.

Design/methodology/approach

Semi-structured, in-depth interviews were chosen as the key method for this study. In total, 14 individual interviews were conducted. A trauma-informed research approach was applied to reduce the risk of re-traumatising participants.

Findings

The paper identifies key obstacles as well as “facilitators” of refugees’ and asylum seekers’ health-care experience in the UK and suggests that host families, friends and third-party organisations all play an important role in ensuring refugees and asylum seekers receive the healthcare they need.

Originality/value

To the best of the authors’ knowledge, this is the first qualitative study in the UK that looks at comprehensive health journeys of refugees from their first encounter with health services through to secondary care, highlighting the important role along the way of facilitators such as host families, friends and third-party organisations.
