    In the present study, for the first time, an effort sharing approach based on Inertia and Capability principles is proposed to assess European Union (EU27) carbon budget distribution among the Member States. This is done within the context of achieving the Green Deal objective and EU27 carbon neutrality by 2050. An in-depth analysis is carried out about the role of Economic Decoupling embedded in the Capability principle to evaluate the correlation between the expected increase of economic production and the level of carbon intensity in the Member States. As decarbonization is a dynamic process, the study proposes a simple mathematical model as a policy tool to assess and redistribute Member States carbon budgets as frequently as necessary to encourage progress or overcome the difficulties each Member State may face during the decarbonization pathways.Comment: 41 pages, 17 figure, 21 Tables.

    Exploring the Dynamics of Responses to Food Production Shocks

    Food production shocks can lead to food crises where access to appropriate quantities and quality of food become inadequate, unaffordable, or unreliable on a major scale. While the physical causes of food production shocks are well researched, the dynamics of responses to them are less well understood. This paper reviews those dynamics and includes evidence gathered via interviews of 44 expert practitioners sourced globally from academia, government, industry, think-tanks, and development/relief organizations. The paper confirms that policy interventions are often prioritized for national interests and poorly coordinated at regional and global scales. The paper acknowledges future compounding trends such as climate change and demographic shifts and suggests that while there are signs of incremental progress in better managing the impacts of shock events, coordinated responses at scale will require a paradigm shift involving major policy, market, and technological advancements, and a wide range of public and private sector stakeholders

    An Assessment of Civil Nuclear ‘Enabling’ and ‘Amelioration’ Factors for EROI Analysis

    Nuclear fission is a primary energy source that may be important to future efforts to reduce greenhouse gas emissions. The energy return on investment (EROI) of any energy source is important because aggregate global EROI must be maintained at a minimum level to support complex global systems. Previous studies considering nuclear EROI have emphasised energy investments linked to ‘enabling’ factors (upstream activities that enable the operation of nuclear technology such as fuel enrichment), have attracted controversy, and challenges also persist regarding system boundary definition. This study advocates that improved consideration of ‘amelioration’ factors (downstream activities that remediate nuclear externalities such as decommissioning), is an important task for calculating a realistic nuclear EROI. Components of the ‘nuclear system’ were analysed and energy investment for five representative ‘amelioration’ factors calculated. These ‘first approximation’ calculations made numerous assumptions, exclusions, and simplifications, but accounted for a greater level of detail than had previously been attempted. The amelioration energy costs were found to be approximately 1.5–2 orders of magnitude lower than representative ‘enabling’ costs. Future refinement of the ‘amelioration’ factors may indicate that they are of greater significance, and may also have characteristics making them systemically significant, notably in terms of timing in relation to future global EROI declines

    Exploring the utility of internal whistleblowing in healthcare via agent-based models

    Objective The benefits of internal whistleblowing or speaking-up in the healthcare sector are significant. The a priori assumption that employee whistleblowing is always beneficial is, however, rarely examined. While recent research has begun to consider how the complex nature of healthcare institutions impact speaking-up rates, few have investigated the institutional processes and factors that facilitate or retard the benefits of speaking up. Here we consider how the efficacy of formal inquiries within organisations in response to employees’ speaking up about their concerns affects the utility of internal whistleblowing. Design Using computational models, we consider how best to improve patient care through internal whistleblowing when resource and practical limitations constrain healthcare operation. We analyse the ramifications of varying organisational responses to employee concerns, given organisational and practical limitations. Setting Drawing on evidence from international research, we test the utility of whistleblowing policies in a variety of organisational settings. This includes institutions where whistleblowing inquiries are handled with varying rates of efficiency and accuracy. Results We find organisational inefficiencies can negatively impact the benefits of speaking up about bad patient care. We find that, given resource limitations and review inefficiencies, it can actually improve patient care if whistleblowing rates are limited. However, we demonstrate that including softer mechanisms for internal adjustment of healthcare practice (eg, peer to peer conversation) alongside whistleblowing policy can overcome these organisational limitations. Conclusion Healthcare organisations internationally have a variable record of responding to employees who speak up about their workplace concerns. Where organisations get this wrong, the consequences can be serious for patient care and staff well-being. The results of this study, therefore, have implications for researchers, policy makers and healthcare organisations internationally. We conclude with a call for further research on a more holistic understanding of the interplay between organisational structure and the benefits of whistleblowing to patient care

    Social ecology of resilience and Sumud of Palestinians

    Get PDF
    The aim of this paper is to provide an overview of theoretical perspectives and practical research knowledge in relation to ‘resilience’, the resilience of Palestinians in particular, and the related concept of ‘Sumud’. ‘Sumud’ is a Palestinian idea that is interwoven with ideas of personal and collective resilience and steadfastness. It is also a socio-political concept and refers to ways of surviving in the context of occupation, chronic adversity, lack of resources and limited infrastructure. The concept of ‘resilience’ has deep roots, going back at least to the 10th century when Arabic scholars suggested strategies to cope with life adversity. In Europe, research into resilience extends back to the 1800s. The understanding of resilience has developed over four overlapping waves. These focus on: individual traits; protective factors; ecological assets; and (in the current wave) social ecological factors. The current wave of resilience research focuses on the contribution of cultural contextualisation and is an approach that is discussed in this paper, which draws on Arabic and English language literature located through a search of multiple databases (CINAHL, British Nursing Index, ASSIA, Medline, PsycINFO, and EMBASE). Findings suggest that ‘Sumud’ is linked to the surrounding cultural context and can be thought of as an innovative, social ecological, approach to promoting resilience. We show that resilience is a prerequisite to ‘Sumud’, meaning that the individual has to be resilient in order to stay and not to leave their place,position or community. We close by pressing the case for studies which investigate resilience especially in underdeveloped countries such as Palestine, and which reveal how resilience is embedded in pre-existing cultural contexts

    Influences on energy supply infrastructure: A comparison of different theoretical perspectives

    Changes to the energy supply infrastructure are a vital component of climate change mitigation strategies. But what exactly underlies changes to energy supply infrastructure? This paper, through exploration and critical analysis of relevant literature, explores the various underpinning influences on energy infrastructure supply using a comparison of different theoretical perspectives. These influences were explored with specific emphasis on techno-economics, social psychology, socio-technical transitions, social practices and institutional dimensions to energy supply. The aim was to have a better understanding of the (direct and indirect) role of politics and the political system in influencing energy supply infrastructure decisions through the various theoretical lenses. The study revealed that techno-economics uses financial instruments and market information as intervention tools. Its effectiveness is measured by social welfare and cost effectiveness. Social psychology uses a combination of information, incentives and innovative informative instruments as its intervention tools. Its effectiveness is measured by behavioural change. Institutions use regulatory instruments as its intervention tool. Its effectiveness is measured by regulatory compliance. Social practices look at change in broader social systems. Its effectiveness is measured by social change. Socio-technical transitions focus on determining social movements and social innovations. Its effectiveness is measured by legitimacy and social learning

    Energy Transitions in Nigeria: The Evolution of Energy Infrastructure Provision (1800–2015)

    Get PDF
    The provision of energy infrastructure is essential for economic growth, social cohesion, and environmental sustainability. Understanding the multiple functions and services it provides us requires firstly a deeper understanding of the factors that influence energy infrastructure itself. This paper focusses on the factors that influence the evolution of energy infrastructure in Nigeria. By studying different eras of energy use according to the technologies that were being implemented, resources that were available, and the political practice of the time it is possible to better frame the drivers of energy infrastructure. The paper explores the transitions of how Nigerians managed to obtain the vast majority of energy from food calories and traditional biomass, to the broad portfolio of energy sources that is in use today
