Abstract
Purpose
The purpose of this paper is to examine how active consumers, i.e. consumers that can inter-temporally shift their load, can influence electricity prices. As demonstrated in this paper, inter-temporal load shifting can induce negative electricity prices, a recurring phenomenon on power exchanges.
Design/methodology/approach
The paper presents a novel electricity-market model assuming a nodal-pricing, energy-only spot market with active consumers. This study formulates an economic equilibrium problem as a linear program and uses an established six-node case study to compare equilibrium prices of a model with inflexible demand to a model with flexible demand of active consumers.
Findings
This study illustrates that temporal coupling of hourly market clearing through load shifting of active consumers can cause negative electricity prices that are not observed in a model with ceteris paribus inflexible demand. In such situations, where compared to the case of inflexible demand more flexibility is available in the system, negative electricity prices signal lower total system costs. These negative prices result from the use of demand flexibility, which, however, cannot be fully exploited due to limited transmission capacities, respectively, loop-flow restrictions.
Originality/value
Literature indicates that negative electricity prices result from lacking flexibility. The results illustrate that active consumers and their additional flexibility can lead to negative electricity prices in temporally coupled markets, which in general contributes to increased system efficiency as well as increased use of renewable energy sources. These findings extend existing research in both the area of energy flexibility and causes for negative electricity prices. Therefore, policymakers should be aware of such (temporal coupling) effects and, e.g. continue to allow negative electricity prices in the future that can serve as investment signals for active consumers.

Abstract
Purpose
Chocolate production and cocoa supply chains are rife with social and environmental challenges. Chocolate companies commonly make claims that their products are “sustainable”, giving little guidance on what this means. The aim of this paper is to conduct a scoping review to synthesise the accounting literature related to the chocolate industry and sustainability and develop a research agenda for accounting scholarship.
Design/methodology/approach
The scoping review followed Arksey and O’Malley’s (2005) five-stage framework for a scoping review. Nineteen accounting journals were searched for literature on “chocolate OR cocoa AND sustainability” from 2000 to 2023. A total of 171 papers were identified through the search, of which 18 were deemed relevant and included for thematic analysis. The themes are analysed using a conceptual framework on accountability.
Findings
Analysis of the relevant literature revealed three distinct perspectives on sustainability in the chocolate industry. These include critique on the problems related to top-down accountability approaches in the chocolate industry; that accountability mechanisms have fallen short in managing sustainability challenges; and that sustainability interventions are driven by profit motives. The themes further reveal a lack of accountability in the industry for marginalised voices.
Originality/value
The scoping review methodology used in this study offers insights into the diverse perspectives on sustainability in the chocolate industry. This research adds valuable knowledge to the field by uncovering nuanced issues around accountability and sustainability and highlighting the need for future research for accountability for sustainable chocolate production.

Abstract
Purpose
This paper aims to investigate the role of virtual training in supporting Sustainable Development Goals (SDGs) and reducing workforce inequalities. It analyzes both the advantages and challenges of integrating virtual training within sustainable development frameworks and the circular economy, underlining its crucial role in transforming workforce strategies and enhancing economic and social progress.
Design/methodology/approach
The study uses Becker’s human capital theory (1964) and Bandura’s social learning theory (1977) to explore the impact of virtual training on human capital development and its contributions to specific SDGs. This integrated approach provides a detailed exploration of how virtual training intersects with sustainable development initiatives.
Findings
The findings highlight the pivotal role of technology in training and development, particularly in the post-pandemic landscape. Virtual training significantly enhances global collaboration, inclusivity and sustainability. It highlights the necessity of adapting corporate training practices to digital environments, thereby improving the quality of education, advancing gender equality and stimulating economic growth.
Originality/value
This paper presents unique perspectives on the influence of workplace training in the post-pandemic era, focusing on technological integration. It discusses how such integration supports diversity, equity and inclusion within the workforce and highlights the essential role of virtual training in promoting organizational flexibility and enhancing employee skills amidst ongoing digital transformations.

Abstract
Purpose
This paper aims to study recent approaches to peacemaking, particularly by Turkey and Russia, in a changing world and their implications for UN-led peace processes. The authors analyze the factors that allow parallel processes to UN mediation to emerge and discuss their influence.
Design/methodology/approach
The paper presents two in-depth case studies of mediation in Syria and Libya, where the UN, as well as Russia and Turkey, were actively involved in peacemaking.
Findings
The authors find that parallel processes to UN mediation emerge if the UN process does not show progress toward a negotiated settlement and other third parties have leverage over the conflict parties. However, whether these parallel processes pose a fundamental challenge to the UN-led process depends on how sustained the third parties’ leverage over the conflict parties is. If it lasts, it puts the UN in a difficult position to either participate in the parallel process and contain it but thereby also legitimizing it, or to abstain from participating but thereby risking to lose control over the mediation process.
Research limitations/implications
Analyzing different approaches to mediation helps to better understand current dynamics of multiparty mediation, including an increased questioning of the effectiveness of UN mediation, and provides insights on how the UN may adapt to keep its relevance in a changing world.
Originality/value
The paper is based on original first-hand data gathered between 2018 and 2022 through more than 50 interviews with UN officials, negotiation team members, political and civil society actors from Syria and Libya, (former) state officials and experts from Russia and Turkey, as well as external observers.

Abstract
Purpose
The purpose of this study was to investigate whether and in what ways library workers in the United States encountered patrons espousing beliefs in conspiracy theories and, if so, to explore the effectiveness of the strategies they used to address information disorder during the interactions.
Design/methodology/approach
The study was designed with an exploratory qualitative approach. Data were collected via an online survey posted to national and state library association listservs, utilizing a self-selected sampling method. Researchers inductively and deductively analyzed results, developing predetermined themes based on the research questions, then iteratively integrating unexpected data during coding.
Findings
A total of 334 responses were received over two weeks. Data represent library workers from 43 states and Washington, D.C., including various types of libraries. Library workers interacted with patrons with conspiratorial thinking, and both library workers and patrons evidenced a range of emotions and motivations.
Originality/value
This is the first national study to survey library workers and whether they encountered patrons espousing conspiracy theories. While the sample size is small, themes elucidate various strategies that library workers use for interacting with patrons who express some level of conspiracy ideation.

Abstract
Pina Bausch is considered one of the most influential choreographers in contemporary dance. She created a new dance language based on a groundbreaking form of joint artistic inquiry. As a leader, Pina Bausch transformed her company into a chosen family of diverse personalities whom she supported in the development of their individual artistic expressiveness. She encouraged her dancers to contribute to her signature style with inventiveness and authenticity. Her ability to integrate the dancers’ contributions into her pieces and bring them to the fore onstage makes Pina Bausch a prime example of creative leadership. While leveraging her company’s collective genius and international fame through boundless curiosity and artistic integrity, Pina Bausch balanced paradoxes of leading innovation. The essence of her leadership style points to the importance of curiosity, humanity, and embodiment in leader-follower relationships.

Abstract
In this study, we examine the impact of audit protection services on individual taxpayer decision making. Audit protection services provide additional support for taxpayers in the event of an audit including preparation and representation. While these services could provide taxpayers with additional confidence, such services could also foster greater reliance on tax software, possibly resulting in riskier tax decisions. Drawing on risk homeostasis theory, we investigate two factors that could affect taxpayer reliance: the amount of taxes owed and the extent of audit protection services. Our results indicate that taxpayers are more likely to rely on tax software prompts when there are full audit protection services and a greater amount of taxes owed. Further, we find that the provision of full audit protection services reduces the likelihood that taxpayers change their tax reporting behavior. Collectively, we provide evidence on taxpayer interactions with tax software.

Case overview/synopsis
In April 2023, Queen Ndlovu, CEO and founder of QP Drone Tech, a provider of drone business solutions, was considering options to fulfil her original dream of manufacturing drones in South Africa. She had encountered obstacles to achieving the same in 2019, and had decided to focus on providing commercial drone consulting services. However, her dream had not extinguished, and in 2022, she decided to restart her efforts. She found practical support from The Innovation Hub, an incubator that was supporting her business, which enabled her to enhance the prototype of her drone. She then had to think about how she would manufacture drones locally by ensuring she had access to production infrastructure, funding, partners and customers. Would she be able to gain a competitive advantage that would differentiate her from competitors? Or should she reconsider whether she should be manufacturing in the first place, as there are risks and benefits for smaller businesses in this regard.

Abstract
Purpose
This study investigates the service quality dimensions of hotel resorts in renowned beach destinations of Thailand. It also explores the relationship between review text sentiment expressed in online platforms and the satisfaction ratings provided for those reviews.
Design/methodology/approach
The study employs a two-step analysis approach: first, supervised and unsupervised machine learning via support vector machine (SVM) and latent Dirichlet allocation (LDA) are used to identify service quality dimensions, and second, SmartPLS with PROCESS macro is applied to analyze the moderating roles of quality signals and reviewer’s experience on the relationship between sentiment and satisfaction rating. The dataset comprises 102,179 online reviews from TripAdvisor, focusing on 187 selected hotels rated from 3 to 5 stars.
Findings
Eight service quality dimensions were identified, including leisure activities, tangibles and surroundings, reliability, responsiveness, service process, food, empathy and ambience. The study underscores that the service process stands as the sole dimension exhibiting negative sentiment. Furthermore, the analysis revealed a robust positive association between sentiment of review texts and satisfaction, and reviewers’ experience and brand affiliation influenced the relationship between customer sentiment and satisfaction.
Practical implications
Hotel managers should focus efforts on maintaining tangible aspects while enhancing existing service quality level of other dimensions, particularly those related to intangible elements. Independent hotels might implement quality audit to ensure that service quality gaps are monitored.
Originality/value
This study contributes an examination of the moderating roles of quality signals and reviewer’s experience on the relationship between review sentiment and satisfaction rating in online reviews.

Abstract
Precise and accurate observation, what we see, and the perception of emotion, what we sense and feel, lead to a more reliable evaluation and thus to better management of complex situations. Therefore, perception, observation and judgement are critical success factors in fostering innovation leadership at individual and team levels. This chapter outlines how these aspects need to be considered to facilitate the discovery, reflection and implementation of new ideas and solutions. We look at scientific areas such as neuroscience and positive psychology and apply the research to different professional areas. Based on this, we introduce ‘Coaching with Art’ as a method to train perceptiveness as a quality for self and team leadership to better cope with the challenges and opportunities of innovation processes.
