Promoting electricity conservation through behavior change: A study protocol for a web-based multiple-arm parallel randomized controlled trial.

BACKGROUND AND AIMS: As a part of the framework of the EU-funded Energy efficiency through Behavior CHANge Transition (ENCHANT) project, the present paper intends to provide a "Research Protocol" of a web-based trial to: (i) assess the effectiveness of behavioral intervention strategies--either single or in combination--on electricity saving, and (ii) unravel the psychological factors contributing to intervention effectiveness in households across Europe. METHODS AND MATERIALS: Six distinct interventions (i.e., information provision, collective vs. individual message framing, social norms, consumption feedback, competitive elements, and commitment strategies) targeting electricity saving in households from six European countries (i.e., Austria, Germany, Italy, Norway, Romania, and Türkiye) are evaluated, with an initial expected samples of about 1500 households per country randomly assigned to 12 intervention groups and two control groups, and data is collected through an ad-hoc online platform. The primary outcome is the weekly electricity consumption normalized to the last seven days before measurement per person per household. Secondary outcomes are the peak consumption during the last day before measurement and the self-reported implementation of electricity saving behaviors (e.g., deicing the refrigerator). The underlying psychological factors expected to mediate and/or moderate the intervention effects on these outcomes are intentions to save electricity, perceived difficulty of saving energy, attitudes to electricity saving, electricity saving habit strength, social norms to save electricity, personal norms, collective efficacy, emotional reaction to electricity consumption, and national identity. The intervention effectiveness will be evaluated by comparing psychological factors and consumption variables before and after the intervention, leading to a 14 (groups including 2 control groups) × 6 (time) mixed factorial design, with one factor between (group) and one factor within subjects (time)-6 measurements of the psychological factors and 6 readings of the electricity meters, which gives then 5 weeks of electricity consumption. RESULTS: Data collection for the present RCT started in January 2023, and by October 2023 data collection will conclude. DISCUSSION: Upon establishing feasibility and effectiveness, the outcomes of this study will assist policymakers, municipalities, NGOs, and other communal entities in identifying impactful interventions tailored to their unique circumstances and available resources. Researchers will benefit from a flexible, structured tool that allows the design, implementation and monitoring of complex interventions protocols. Crucially, the intervention participants will benefit from electricity saving strategies, fostering immediate effectiveness of the interventions in real-life contexts. TRIAL REGISTRATION: This trial was preregistered in the Open Science Framework: https://osf.io/9vtn4.

Effectiveness and costs of a low-threshold hearing screening programme (HörGeist) for individuals with intellectual disabilities: protocol for a screening study.

INTRODUCTION: Individuals with intellectual disabilities (ID) often suffer from hearing loss, in most cases undiagnosed or inappropriately treated. The implementation of a programme of systematic hearing screening, diagnostics, therapy initiation or allocation and long-term monitoring within the living environments of individuals with ID (nurseries, schools, workshops, homes), therefore, seems beneficial. METHODS AND ANALYSIS: The study aims to assess the effectiveness and costs of a low-threshold screening programme for individuals with ID. Within this programme 1050 individuals with ID of all ages will undergo hearing screening and an immediate reference diagnosis in their living environment (outreach cohort). The recruitment of participants in the outreach group will take place within 158 institutions, for example, schools, kindergartens and places of living or work. If an individual fails the screening assessment, subsequent full audiometric diagnostics will follow and, if hearing loss is confirmed, initiation of therapy or referral to and monitoring of such therapy. A control cohort of 141 participants will receive an invitation from their health insurance provider via their family for the same procedure but within a clinic (clinical cohort). A second screening measurement will be performed with both cohorts 1 year later and the previous therapy outcome will be checked. It is hypothesised that this programme leads to a relevant reduction in the number of untreated or inadequately treated cases of hearing loss and strengthens the communication skills of the newly or better-treated individuals. Secondary outcomes include the age-dependent prevalence of hearing loss in individuals with ID, the costs associated with this programme, cost of illness before-and-after enrolment and modelling of the programme's cost-effectiveness compared with regular care. ETHICS AND DISSEMINATION: The study has been approved by the Institutional Ethics Review Board of the Medical Association of Westphalia-Lippe and the University of Münster (No. 2020-843 f-S). Participants or guardians will provide written informed consent. Findings will be disseminated through presentations, peer-reviewed journals and conferences. TRIAL REGISTRATION NUMBER: DRKS00024804.

Tackling climate change at the city level: insights from Lighthouse Cities' climate mitigation efforts.

Introduction: The link between lifestyles and Greenhouse Gas (GHG) emissions has prioritized climate mitigation strategies of cities worldwide. As cities have increasingly generated GHG emissions by their industrial and transportation activities, their role in climate mitigation has gained prominence. Cities' climate mitigation policies to reduce the GHG intensity of their residents' daily lives are one of their significant efforts to tackle climate change. Lighthouse Cities (LCs), in particular, have emerged as remarkable actors in promoting lifestyle changes for their residents. Methods: This study examines climate mitigation strategies of LCs of Climate CAMPAIGNers project, including Baku, Vilnius, Lahti, Izmir, Trujillo, Athens, Linz, Milan, Cape Town, Dublin, and Skopelos, addressing lifestyle changes by conducting an expert survey in 11 LCs involving 89 respondents. The findings of the expert survey are comparatively analyzed across 11 LCs. Results: The results show that experts form Lighthouse Cities identify increasing awareness and information provision as a significant component of climate mitigation policies. Concerning lifestyle changes, strategies toward energy efficiency and sustainable mobility are highlighted as the primary areas to be prioritized. Discussion: This study enhances the understanding of cities' capacity to reduce their residents' GHG emissions. The findings can be utilized to identify and tailor policies for supporting the Lighthouse Cities in their climate change mitigation efforts and provide pointers for selecting the lifestyle changes that can be promoted and prioritized in Lighthouse Cities.

Current state and call for action to accomplish findability, accessibility, interoperability, and reusability of low carbon energy data.

With the continued digitization of the energy sector, the problem of sunken scholarly data investments and forgone opportunities of harvesting existing data is exacerbating. It compounds the problem that the reproduction of knowledge is incomplete, impeding the transparency of science-based targets for the choices made in the energy transition. The FAIR data guiding principles are widely acknowledged as a way forward, but their operationalization is yet to be agreed upon within different research domains. We comprehensively test FAIR data practices in the low carbon energy research domain. 80 databases representative for data needed to support the low carbon energy transition are screened. Automated and manual tests are used to document the state-of-the art and provide insights on bottlenecks from the human and machine perspectives. We propose action items for overcoming the problem with FAIR energy data and suggest how to prioritize activities.

Tracheal Resection after Previous Treatment Provides Comparable Outcome to Primary Surgery.

BACKGROUND: Tracheal and laryngotracheal surgery provides both excellent functional results and long-term outcomes in the treatment of tracheal stenosis. Consequently, challenging re-resections are rarely necessary. The purpose of this study was to compare the outcome of (laryngo-)tracheal re-resection and surgery after bronchoscopic interventions with that of primary surgery. METHODS: Patients undergoing resection for benign tracheal stenosis at our center between 1/2016 and 4/2020 were included. Perioperative characteristics and functional outcomes of patients were used for statistical analysis. RESULTS: Sixty-six patients who underwent (laryngo-)tracheal resection were included (previous resection [A = 6], previous stent [B = 6], previous bronchoscopic intervention w/o stenting [C = 19], untreated [D = 35]). Baseline parameters were largely comparable between groups with exception from group B that had significantly worse lung function. Group A necessitated more complex reconstructions (end-to-end: n = 1: 17%| cricotracheal n = 2: 33%| cricotracheal with mucosectomy n = 2: 33%| laryngoplasty: n = 1: 17%) than patients in group D (end-to-end n = 21: 60%| cricotracheal n = 14: 40%). Postoperative outcomes were comparable throughout groups (intensive care unit: 1[1-18] days; hospital stay: 8[5-71] days). Anastomotic complications were higher after previous stenting (A: 0%; B: 33.3%; C: 10.5%; D: 2.9%; B/D p = 0.008| surgical revisions: A: 16.7%; B: 33.3%; C: 0%; D: 5.7%; B/D, p = 0.035). Overall, postoperative lung function was significantly better (forced expiratory volume in 1 second: 63% ± 24 vs. 75% ± 20; p = 0.001 | PeakEF 3.3 ± 1.9 vs. 5.0 ± 2.2L; p = 0.001). No 90-day mortality was observed in any group. Median follow-up was 12(1-47) months. CONCLUSION: In carefully selected patients treated in a specialized center, tracheal or laryngotracheal resection after previous tracheal interventions provides comparable outcome to primary surgery.

The Significance of Enabling Human Consideration in Policymaking: How to Get the E-Ferry That You Want.

There is broad agreement in literature and policy that the transport sector needs to maximise electric mobility, in order to lower both energy consumption and greenhouse gas emissions. This ongoing transformation continues to require a high degree of technological innovation. Consequently, policymakers are striving to reward innovation in procurement tender contracts, in order to achieve sustainable innovation. At the same time, such contracts are often designed with a principle of technology neutrality in mind, to prevent any distortion of the market logic. This article suggests that it is misguided to try to perfect the logic of the tender system and that articulating contract that rewards innovation is no guarantee of a sustainable solution. Rather than being technological, the problem should be seen as moral: the mounting environmental challenge. Policymakers thus have clear ideas about the action needed based on what they, through moral conviction, consider to be appropriate action. This case study-conducted as a part of the EU H2020-funded ECHOES Project under Work Package 6-on the electrification of the Flakk-Rørvik ferry connexion reveals how policymakers were able to achieve the intended results: in this case, an e-ferry rather than a biodiesel ferry, in spite of, rather than because of, the tender system logic. They achieved this by involving stakeholders in the process with a continuous and uninterrupted dialogue. The project stakeholders were able to intervene in the tender system logic in favour of human considerations. We argue that this project was a success because human judgement, not system logic, was the driving force. By extension, we argue that systems will only allow policymakers to pursue moral issues to the degree that they allow human intervention.

Understanding the Factors Affecting Sustainable Energy Action Plan: A Case Study From the Covenant of Mayors Signatory Municipality in the Aegean Region of Turkey.

This study presents the case of a Metropolitan Municipality in the Aegean Region of Turkey, which undertook a series of initiatives to conduct projects on environmental protection and sustainability. This case study was conducted as two separate studies as a part of Horizon 2020-funded ECHOES project under Work Package 6, aiming to gain insight into the collective magnitudes of energy-related choices and behavior. The starting point of the process is marked, in 2015, by the municipality becoming a party to the Covenant of Mayors movement, joining around 8,000 signatories from over 50 countries. In line with European Union's (EU's) climate targets and associated energy-related policies, signatories of the Covenant of Mayors aim to decrease carbon emissions by 20% by 2020 and by 40% by 2030. In order to enhance the design and operationalization of policies for achieving these targets, each partner in the Covenant of Mayors is required to develop a Sustainable Energy Action Plan (SEAP). The SEAP is to be prepared within 2 years of becoming a party to the Covenant of Mayors and involves action plans and projects in order to operationalize the strategies for achieving the associated targets. To this end, this study analyzes the Metropolitan Municipality's SEAP and its components, which include zero-emission public transportation project, transformation of existing buildings to a more energy-efficient standard and related energy audit studies, a project for decreasing waiting periods in traffic via a Smart Traffic System, a pedestrianization project, and a project for increasing the use of geothermal energy for district heating. This study set out to identify the internal and external factors, as well as bottom-up and top-down mechanisms involved in various phases of the preparation and implementation of the SEAP. The research method was expert interviews, incorporating viewpoints and perceptions of stakeholders from different levels of the municipality. Among the key results are understanding the roles of enthusiasts and frontrunners in such initiative and the importance of top-management and central government support.

Psychological Processes and Institutional Actors in the Sustainable Energy Transition: A Case-Study Analysis of a Local Community in Italy.

This paper presents the results of a qualitative study exploring the role of formal social units in the sustainable energy transition process. A small community in North-east Italy was assumed as case study, in the context of a wider EU-funded research project aimed at understanding the individual and collective dimensions of energy-related choices. Starting from a general framework and integrated approach to explain sustainable energy transitions proposed by Steg et al. (2015), the main aim of our study was to identify the psychological and social factors that motivated the key actors to undertake an energy self-sufficiency path in the case-study area. Our analyses aimed at understanding the social, cultural, and socioeconomic dynamics in the energy transition process of the community. The study outlined how these factors contributed to foster collaborative actions between public decision makers, relevant stakeholders, civil society, and citizens. Results of a computer-supported qualitative content analysis using the software MAXQDA helped to shed light on the specific mechanisms and dynamics driving energy choices and energy-related behavior among the community. The implication for best practices and successful implementations of energy transition process in small communities emerging from this case study are discussed.

Investigating the trends in arctic research: The increasing role of social sciences and humanities.

The Arctic Region experienced a series of significant changes due to shifting climate conditions, resulting in multiple opportunities and challenges for international actors, and encouraging both Arctic and non-Arctic states to promote their own national interests. Hence, the region has become a global priority, and a focus of scientific studies across the Natural Sciences, and Social Sciences and Humanities (SSH) disciplines. This study systematically analyses the literature on the Arctic Region, conducting a multidimensional bibliometric analysis and content analysis on the basis of semantic clustering. The purpose of the analysis is to determine future Arctic-related research themes. The study follows a three-level research framework. The first level of the analysis highlights a disciplinary shift in the Arctic literature from Natural Sciences towards Social Sciences and Humanities, particularly, focusing on the environment, technology, political and energy-related issues. The second level identifies 9 research themes which are validated in the third level. The third level reveals the most prominent terms and prioritized research areas in the Arctic literature, namely, Governance, Security Issues, Economic Factors, Legal Issues, Energy and Natural Resources, Logistics, Climate Change and Environment, Technology, and Socio-cultural and Ethnic Issues.
