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
Following victimisation of many types, knowing one is not alone in their experience, or the reactions to that experience, has been identified as comforting and supportive of recovery in survivors of violence and abuse. Information is often provided by support groups, professionals, or victim/survivor organisations, which still fill a significant gap in the criminal justice system, which offers insufficient support to victims of crime. However, as many victims do not engage with support services or the criminal justice system, they may be at risk of not receiving such crucial support. The rising popularity of so called ‘hashtag activism’ has however provided victims and survivors with a worldwide platform to share experiences, reactions, information, support, and solidarity. This chapter explores the impact of key hashtags, such as #metoo and #BlackLivesMatter, via a critical evaluation of outcomes, including policy, cultural, and legislative impact, to unpick their successes and failures, with a focus on support and community-building, marginalisation and performative allyship.

To measure the relationships between varieties of patriotism and fan reactions to anthem-linked athlete activism and to test the effects of teammate allyship.
Abstract
Purpose
To measure the relationships between varieties of patriotism and fan reactions to anthem-linked athlete activism and to test the effects of teammate allyship.
Design/methodology/approach
In this study of US sport fans (n = 519), the authors examine whether two varieties of patriotism—the affective “symbolic patriotism” and the cognitive “uncritical patriotism”—might explain fans' reactions (support v. opposition) to anthem-linked athlete activism. The authors also consider whether fans' acceptance of nonactivist teammate allyship moderates patriotism influences on those reactions.
Findings
Using partial least squares structural equation modelling (PLS-SEM), the authors posit and show that fans' reactions to athlete activism are driven more strongly by uncritical patriotism than by symbolic patriotism. The authors also show that fans' acceptance of nonactivist teammate allyship significantly moderate the strength and direction of fans' reactions to athlete activism.
Research limitations/implications
The authors contribute substantive, new knowledge into the sways of athlete activism, teammate allyship and fan patriotism within the sport world. By way of novel heterotrait-monotrait ratio of correlations, the authors show evidence of discriminant validities of symbolic patriotism and uncritical patriotism. Using PLS-SEM moderation tests, the authors also show that fans' acceptance of teammate allyship moderates the influences of these patriotism types differently.
Originality/value
Few empirical studies to date have investigated sport fans' reactions to athletes' displays of social activism (e.g. taking a knee to protest racism).

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
Purpose
This study aims to examine the extent to which organizational dissent predicts perception of workplace bullying. As previous studies have reported inconsistent and sometimes contradictory results regarding the interaction between the reporting of bullying and demographic variables, these variables are examined in the New Zealand context. Organizational communication research provides considerable insight into the ways individuals make sense of and resist workplace bullying through juxtaposition with the concepts of dissent and intragroup conflict.
Design/methodology/approach
A nationally representative sample of managers in New Zealand (n = 239) was conducted. Surveys included demographic questions and the following measures: Organizational Dissent Scale and Negative Acts Questionnaire Revised Scale.
Findings
Key results and indications for further research are highlighted by the third model in this study. First, workers who reported they engaged in either articulated dissent or latent dissent were more likely to perceive workplace bullying. Second, workers who are more likely to express contrary opinions in the workplace are more likely to recognize, acknowledge and tolerate less positive interactions in the workplace such as bullying.
Originality/value
To the best of the authors’ knowledge, this study is the first to analyze dissent and bullying in the New Zealand context. Second, this research raises the question of whether there is a conflation of work-related bullying behaviors and bad leadership styles that may not be targeted (e.g. authoritative leadership and micromanaging). Finally, communication research provides a distinctive contribution by exploring the narrative form of worker responses to perceived bullying. In this manuscript, the authors examine potential predictors on the perception of workplace bullying in the context of New Zealand, particularly focus on the relationship between dissent and the perception of workplace bullying.

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.

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
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.
