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

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.

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

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.

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.

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.

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.

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.

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.

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

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.

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.

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

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.

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

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

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.

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.

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.

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.

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

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

Academic research has supported the belief that consumers undertip minority race service workers due to implicit racial biases. However, there has been less focus in examining possible moderating factors. This paper aims to fill this gap by analyzing the role of direct and indirect experience in tipping frontline service workers from a minority background. Given the prominence of customer ratings on digital service platforms and the perception that African Americans are discriminated against, the authors look at the interplay of interaction length (direct experience) and customer ratings (indirect experience) on the relationship between race and tipping.

An expectancy disconfirmation framework was developed and tested with a sample of 360 US participants in an online experiment. The experiment followed a 2 × (race: African-American versus Caucasian) × 2 (direct experience: limited versus extensive) × 3 (indirect experience: absent versus positive versus negative customer rating) design.

The authors found consumers who have extended direct experience (longer service interaction) and no indirect experience (absent customer ratings) tipped African Americans more than Caucasians. Interestingly, this effect is reduced in the presence of indirect experience (customer ratings). Finally, where the consumer lacks direct experience (shorter service interaction) but is exposed to positive indirect experience (positive customer ratings), consumers tip African Americans more.

To the best of the authors’ knowledge, this is the first paper that examines the role of direct and indirect experience in the relationship between race and tipping. Based on the authors’ findings, the authors provide several contributions, including recommendations to reduce inequalities arising from implicit racial bias on digital service platforms.

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.

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).

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.

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

Creating high quality, liveable urban settings that facilitate a transition to lower carbon living and work environments is central to achieving more sustainable cities and communities. For over two decades, city builders and planners have advocated compact growth to facilitate these transformations. The impact of the COVID-19 pandemic has heralded a conceptual shift in debates on urban density, mobility and accessibility with the idea of the ‘15-minute city’ (Moreno, 2016) gaining increased prominence and traction among policymakers. Popularised by Mayor Anne Hidalgo of Paris, proximity and accessibility, together with density, underpin an ideal that privileges the relocalisation of work, home and leisure activities. Broadly described, the concept centres on the (re)development of urban neighbourhoods where basic services – access to public transport, grocery, social and healthcare, leisure and amenity – can be provided within a 10-, 15- or 20-minute walk or cycle from home. Since the publication of the National Planning Framework in 2018, more compact urban growth has become a core principle underpinning spatial planning at a range of scales in Ireland and the development of low-carbon and vibrant urban centres is now a key objective of Irish policymakers. The Southern Regional Assembly has been promoting the ‘10-minute town’ ideal through its Regional Spatial and Economic Strategy (RPO 176) and pilot projects in 3 medium sized towns (Carlow, Tralee and Ennis). However, scaling up the concept to accommodate the region's larger cities is relatively unexplored. As the smallest of the three cities in the southern region, and with significant redevelopment potential at the heart of the urban core, Waterford is in a dynamic position to accommodate the 15-minute concept. Furthermore, Waterford's more recent population growth suggests the need to cement the 15-minute city concept as a baseline for the design of the city as it develops and evolves in both new and emerging neighbourhoods. This chapter examines the potential and challenges of embracing the 15-minute city concept in Waterford as a way to meet the objectives set out in the National Planning Framework, Regional Spatial and Economic Strategy and by Waterford City Council, and discusses lessons for the Irish context more broadly. The chapter concludes that while the framework conditions for success appear to be largely in place, whether the governance and political system at the metropolitan and local levels is courageous enough to embrace and harness these opportunities remains to be seen.
