In recent years, the target of reaching “net zero” emissions by 2050 has come to the forefront of global climate politics. Net zero would see carbon emissions matched by carbon removals and should allow the planet to avoid dangerous climate change. But the recent prominence of this goal should not distract from the fact that there are many possible versions of net zero. Each of them will have different climate justice implications, and some of them could have (...) very negative consequences for the world's poor. This article demonstrates the many ambiguities of net zero, and argues in favor of a net zero strategy in which those who can reasonably bear the burden adopt early and aggressive mitigation policies. We also argue for a net zero strategy in which countries place the lion's share of their faith in known emissions reduction approaches, rather than being heavily reliant on as-yet-unproven “negative emissions techniques.” Our overarching goal is to put net zero in its place, by providing a clear-sighted view of what net zero will achieve, and where the “net” in net zero needs to be tightened further if the world is to achieve climate justice.

To achieve the very specific goal of reducing net greenhouse gas emissions to zero by 2050, many technical challenges and conflicts of interest must be overcome. How can a strategy be developed that is politically and socially acceptable? Research is needed to support societal efforts to rethink the links between energy use and human well-being.

Corporate net-zero carbon emission pledges abound and so does skepticism about the results they could deliver. Three approaches proposed here can ensure these pledges alleviate, rather than aggravate, the climate crisis.

To contribute to a better understanding of the determinants of climate-friendly organizational behavior, we study the potential of behavioral policy interventions and social norms to foster individual contributions to organizational decarbonization initiatives. We investigate the effects of different types of behavioral policy interventions (default nudges vs. short-term boosts) in isolation and when they are combined with normative appeals to adopt climate-friendly behaviors in an organizational context. In a 2 × 2 between-subjects experiment, we find that default nudges generally induced higher (...) individual contributions to organizational carbon compensation programs than short-term boosts. Moreover, injunctive social norm information decreased the effectiveness of both types of behavioral interventions but affected the effectiveness of short-term boosts to a stronger extent than the effectiveness of default nudges. Contributing to the nascent literature on motivating climate change mitigating behaviors in organizational contexts, we additionally explore whether factors such as personality traits, pro-social and pro-environmental beliefs, attitudes, and behaviors, and the degree of organizational identification exert an influence on the effectiveness of the interventions and provide qualitative insights into participants’ reasoning for their decisions.

Both theory and experiments indicate that the vacuum is not a state of empty space, but is populated by electromagnetic fluctuations at a lowest nonzero level, the Zero Point Energy (ZPE). This debouches into considerable changes of fundamental physics, as shown by a revised quantum electrodynamic theory (RQED) applied to elementary particles, and by a revised ZPE frequency spectrum applied to the expanding universe. The Standard Model based on a vacuum state of empty space is thus replaced by RQED, (...) thereby resulting in massive elementary particles from the beginning, independently of the theory by Higgs. Also the basic properties of the Higgs-like particle detected at CERN can be reproduced by RQED. It further leads to new fundamental results beyond the theories by Dirac and Higgs, such as to a deduced value of the elementary net charge, magnetic confinement of charged particle configurations, intrinsic local particle charges, photon spin with a very small but nonzero photon rest mass, and needle-like particle-wave properties which contribute to the understanding of the photoelectric effect and two-slit experiments. The real macroscopic pressure due to the revised ZPE frequency distribution further influences the dynamics of the expanding universe, by the ZPE photon pressure gradient acting as dark energy, and the ZPE photon energy density acting as dark matter. This results in a model being consistent with the observed scale, the rate of expansion, and the stability of a flat expanding observable universe. EWW141009DXN. (shrink)

In 1937 Joan Robinson proposed that “when capitalism is rightly understood, the rate of interest will be set at zero and the major evils of capitalism will disappear”. A permanent zero rate would abolish capitalist profit except in limited cases, leaving nearly all output to be claimed by labour as wages. It would allow capital to be allocated on the basis of prospective social benefit rather than short-term profitability and a collateral basis that favours the wealthy. It would (...) remove some of the economic pressure to use resources unsustainably. So why not do this? I argue that the few available philosophical arguments for positive interest rates are unsatisfactory. Those who want a just and sustainable form of capitalism should target net zero for the interest rate. (shrink)

States and other climate actors now commonly set ‘net zero’ targets – pledging that, by a certain date, they will put no more carbon into the atmosphere than they take out. However, there is controversy over what exactly should count as attaining such targets. The method of emissions accounting that states currently use – territorial emissions accounting – is often criticized as problematic, but a fully satisfactory explanation of the problem is needed. We argue that the key both to (...) understanding the problem and to solving it is that there is a specific kind of cooperative contribution – a mereological contribution – that a national net zero commitment needs to make to global climate action in order to meet the standards that global citizens should hold states to. On this basis, we propose an alternative method – Contributory Value-Chain Accounting – showing how it can be qualified to reflect trade relationships between net-zero-aligned countries, and defending it against the objections that it involves double counting, is infeasible and too informationally demanding, and that it would send the wrong incentive signals.

We investigate in detail the electromagnetic fields of a uniformly accelerated charge, in order to ascertain whether such a charge does ‘emit’ radiation, especially in view of the Poynting flow computed at large distances and taken as an evidence of radiation emitted by the charge. In this context, certain important aspects of the fields need to be taken into account. First and foremost is the fact that in the case of a uniformly accelerated charge, one cannot ignore the velocity fields. (...) This then leads to other equally vital points. The net field energy turns out to be exactly the same as that of a non-accelerated charge having a uniform velocity equal to the instantaneous velocity of the uniformly accelerated charge. Further, the Poynting vector, seen with respect to the ’present’ location of the uniformly accelerated charge, during the deceleration phase, possesses everywhere a radial component pointing inward toward the charge, becoming nil when the charge becomes momentarily stationary, and during the acceleration phase, points away from the charge position. Last, but not least, when the leading spherical front of the relativistically beamed Poynting flux, advances forward at a large time t to a far-off distance \, the charge too is not lagging far behind. In fact, these relativistically beamed fields, increasingly resemble fields of a charge moving in an inertial frame with a uniform velocity \, with a convective flow of fields in that frame along with the movement of the charge. There is no other Poynting flow in the far-zones that could be termed as radiation emitted by the charge which, in turn, is fully consistent with the absence of radiation reaction and is also fully conversant with the strong principle of equivalence.

Meeting the net zero emission targets set by many states after the Paris Agreement to help keep global warming well below 2°C above pre-industrial levels will require carbon dioxide removal technologies (CDRs). Several moral concerns arise if the contribution of CDRs to achieving net zero is not specified, but such concerns can be met by defining a permissible target for CDRs. This paper proposes a framework for defining the permissible contribution of CDRs to the net zero targets (...) of individual states. The framework identifies three categories of emissions for which the permissibility of CDRs varies depending on the ethical costs of both emission abatement and CDRs. We argue that a) luxury emissions should be reduced without using CDRs; b) emissions for full membership in society should be abated by structural efforts, although using CDRs is permissible, given certain conditions; and c) CDRs are permissible for residual emissions because otherwise net zero targets cannot be reached.

Carbon offsets either remove greenhouse gases from the air or prevent emissions thereof. They face questions both economic (is ‘net zero’ really reached?) and moral. I defend the moral permissibility of off-sets. They likely shift climate harms around, but that need not be unjust—and in any case we cannot avoid doing that.

Recognising and responding to injustices that benefit us is a pervasive problem of contemporary life, and arguably a mark of moral seriousness in anyone who presumes to take moral stands at all. In response, a number of authors have defended the view that such benefits normally bring with them prima facie obligations of compensation. This ‘wrongful-benefits’ approach has considerable intuitive plausibility, much of it founded in the financial metaphor that gives it an appearance of precision. Yet while the compensation scenario (...) works reasonably well in one-off cases such as receiving stolen property, it yields incoherent results when facing ongoing structural injustices. In such cases ‘innocence’ is ambiguous and our status as beneficiaries and victims is complex. In contrast, solidarity — understood as a principle of equity requiring that we side with the least well off — provides a better account of duties to respond to structural injustice. In solidarity the agent follows the lead of organised out-groups and defers to their judgment about collective actions to overcome injustice. Solidarity leads us to support the organised group that suffers from the greatest inequity. Solidarity does not use a financial metaphor and thus it neither requires full disgorgement, nor absolves us of further action when we reach the point of net-zero benefit. Rather, solidarity is a principal means for ordinary citizens to promote equity by affirming the equal status of the victims, and to atone for having benefited from injustice, whether they did so willingly or otherwise.

Tracking and goal setting are popular approaches in the personal health and fitness industry. In this paper we use a similar approach to assist users in their journey for a more sustainable lifestyle, starting with food. We employ Action Design Research (ADR) methodology to develop an application and subsequently propose design principles for developing blockchain-based applications for assisting users on their path to eating environmentally friendly food. The path to a sustainable lifestyle can be hard as individuals often do not (...) realize their personal impact towards achieving a net zero carbon future. To address this shortcoming, this study conducts an ADR experiment to create affordances for users to learn, create impact and realize that they are not alone in this journey thus motivating users to a sustainable lifestyle. The design principles that emerged from the project are design for categories and labels, design for measuring collective impact, and design for rewards and redemption. (shrink)

Designing policy for climate change requires analyses which integrate the interrelationship between the economy and the environment. We argue that, despite their dominance in the economics literature and influence in public discussion and policymaking, the methodology employed by Integrated Assessment Models (IAMs) rests on flawed foundations, which become particularly relevant in relation to the realities of the immense risks and challenges of climate change, and the radical changes in our economies that a sound and effective response require. We identify a (...) set of critical methodological problems with the IAMs which limit their usefulness and discuss the analytic foundations of an alternative approach that is more capable of providing insights into how best to manage the transition to net-zero emissions.

In response to stakeholder pressure, companies increasingly make ambitious forward-looking sustainability commitments. They then draw on corporate policies with varying degrees of alignment to disseminate and enforce corresponding behavioral rules among their suppliers and business partners. This goal-based turn in private sustainability governance has important implications for its likely environmental and social outcomes. Drawing on paradox theory, this article uses a case study of zero-deforestation commitments in the Indonesian palm oil sector to argue that goal-based private sustainability governance’s characteristics (...) set the stage for two types of paradoxes to emerge: performing paradoxes between environmental, social, and economic sustainability goals, and organizing paradoxes between cooperation and competition approaches. Companies’ responses to these paradoxes, in turn, can explain the lack of full goal attainment and differential rates of progress between actors. These results draw our attention to the complexities hidden behind governance through goal setting in the corporate space, and raise important questions about the viability of similar strategies such as science-based targets and net-zero goals.

Wynes and Nicholas (2017) argue that the most effective action to reduce individual greenhouse gas (GHG) emissions is to have one fewer child. We raise methodological concerns about the way in which the authors attribute responsibility for emissions: they rely on multiple counting when calculating the emissions of future generations, and they exclude scenarios in which global emission trajectories become net-zero or negative. This may distort recommendations from policy makers and educators who rely on their study. We propose an (...) alternative way of attributing responsibility that avoids multiple counting. Investigating the implications of having children under this proposal with regards to the full range of different scenarios, including likelihood analyses, calls for further studies. (shrink)

Significant challenges confronting China include reducing carbon emissions, dealing with the resulting problems, and meeting various requirements for long-term economic growth. As a result, the shift in industrial structure best reflects how human society utilizes resources and impacts the environment. To meet China's 2050 net-zero emissions target, we look at how technological innovations, financial development, renewable energy investment, population age, and the economic complexity index all play a role in environmental sustainability in China. Analyzing short- and long-term relationships using (...) ARDL bounds testing, we used historical data spanning 1990–2018. According to the study's findings, the cointegration between CO2 emissions and their underlying factors was found. The deterioration of the environment directly results from financial development, increasing economic complexity, and population aging. Technical advancements, investments in renewable energy sources, and changes to the industrial structure all contribute to lower CO2 emissions. Granger causality results were also reliably obtained in this study. According to our findings in the fight against environmental problems, a key tool for meeting long-term sustainability goals is policy prescriptions that use technological innovations, renewable energy investment, and industrial structure.

Responding to climate change and avoiding irreversible climate tipping points requires radical and drastic action by 2030. This urgency raises serious questions for energy companies, one of the world’s largest emitters of greenhouse gases (GHGs), in terms of how they frame, and reframe, their response to climate change. Despite the majority of energy companies releasing ambitious statements declaring net zero carbon ambitions, this ‘talk’ has not been matched with sufficient urgency or substantive climate action. To unpack the disconnect between (...) talk and action, this paper draws on the literature on framing, organisational hypocrisy, and collective moral responsibility. We conduct a longitudinal qualitative content analysis of the framing of climate change used by the ten largest European investor-owned energy companies and the actions they have taken to shift their business practices. Our findings reveal three main categories of energy companies: (i) deflecting, (ii) stagnating, and (iii) evolving. We show key differences in the relationship between framing and action over time for each category, revealing how deflecting companies have larger and persistent gaps between green talk and concrete action and how stagnating companies are delaying action despite increased green talk, while evolving companies exhibit a closer link between talk and action that tends to be realised over time. Our analysis reveals how competing approaches to framing collective moral responsibility help understand the trajectories of talk and action across the different categories of energy companies. This research makes several contributions to the literature on organisational hypocrisy and collective moral responsibility in the context of climate change. Our analysis highlights the complex relationship between collective moral responsibility, organisational hypocrisy and climate action, revealing how different collective framings—diffuse, teleological, or agential—can both enable and offset substantive climate action. The study also enriches our understanding of the performative nature of collective moral responsibility by examining its temporal dimensions and showing how an agential, backward-looking focus is associated with more meaningful climate action.

Given their large number of adherents, and the land and property they own, religious communities have been identified as groups that could have an influence on achieving carbon net-zero. The theological views held by religious communities relating to ecological matters – their “ecotheological values” – play an important role in motivating their environmental concern and action. But which ecotheological ideas are most, and which are least, efficacious in this respect? This paper presents findings salient to this question from a (...) recent survey (n = 319) conducted amongst Christian activists and advocates concerned with climate change. It reports on which ecotheological ideas are most widely and firmly held amongst samples from six Christian environmental activist and advocacy groups in the UK, and discusses the extent to which these ideas are either continuous with mainstream Christian theology, or indicate innovative theological thinking. We find examples of both: some mainstream views are popular, and some are unpopular, amongst our sample, whilst some innovative and newer ideas are becoming more popular, whilst others are resisted. These results will be useful in seeking to promote a greater pro-environmental stance within Christian communities more widely. (shrink)

BackgroundTo prevent the planet from catastrophic global warming a reduction of greenhouse gas emissions to net zero is required. Thus, divestment from fossil fuels must be a strategic interest for health insurers. The aim of this study was to analyse the implementation of environmental, social and governance criteria in German private health insurers’ investments.MethodsIn 2019 a survey about ESG strategies was sent to German private health insurance companies. The survey evaluated investment strategies and thresholds for the exclusion of sectors (...) and business practices, as well as company strategies for sustainable business development.FindingsGiven their business reports, German private health insurers manage assets of more than €350 billion. 11 of 40 insurance companies provided quantitative data, 10 refused to answer. According to quantitative data, €66 billion of assets is managed according to any ESG criteria; this equals an average of 76% of each company’s bonds. None of these insurers excluded the production and sale of fossil fuels. All excluded coal mining but only at high thresholds. For €226 billion, no data were provided.InterpretationThe findings are in contrast to the expected intrinsic economic interest of the insurers to stop global warming and improve public health. The majority of assets are managed in a highly problematic manner, especially the absence of capital allocated in fields contrary to medical ethics cannot be presumed. Lack of transparency is a major problem that limits clients in choosing the insurer who has the most advanced ESG criteria. (shrink)

The potential upscaling of carbon dioxide removal (CDR) technologies to meet states’ net-zero targets may enable individuals to remove emissions by purchasing carbon removal certificates. In this paper, I argue for two concepts of individual responsibility to capture the moral responsibility of individuals to remove carbon dioxide from the atmosphere through CDR technologies. The first is that of liability, a direct responsibility to remove carbon in order to minimize one’s carbon footprint. The second is a shared political responsibility to (...) remove carbon that individuals have by virtue of being part of weak collectives responsible for mitigating climate change or by virtue of participating in structures that contribute to climate change. I argue that the concept of shared political responsibility can be used to determine how CDR technologies should or should not be implemented. Finally, I discuss how these two responsibilities are related. (shrink)

Massive consumption of fossil energy since the Industrial Revolution has contributed to carbon dioxide emissions and accumulation. That, in turn, has led to global climate change, which is mainly characterized by warming. The necessity of immediate climate action can be justified from both moral and self-interest perspectives. Achieving the United Nations Intergovernmental Panel on Climate Change goal of getting the world to net-zero carbon by 2050 depends on undermining the libertarian and self-interested arguments that opponents have against trying to (...) reach this goal. First, from an ethical perspective, these opponents wrongly set the free market against the welfare state and individual property rights against the redistribution of social wealth, ignoring the possibility that their own ideal of liberty might require a welfare system. Second, it is also possible to show that morality and self-interest go together here, requiring us to reduce carbon use right now. (shrink)

Deep decarbonization – slashing global greenhouse gas emissions to net-zero – now dominates global climate policy. Two recent books assess feasible routes to achieve deep decarbonization.

In this critical review essay, I summarize and assess both books. (...) In the final section, I raise several normative questions, which the pair of books might lead us to. (shrink)

This handbook entry examines the issue of housing in the Anthropocene. The issue of housing in the Anthropocene involves many factors and aspects with respect to housing given the facts of climate change. To limit these factors and possible through-lines for this entry, housing in the Anthropocene will be analyzed according to three dimensions to make sense of the future of housing needs alongside climate change: (1) Housing and human population. The fundamental questions with respect to housing in the Anthropocene (...) involve human population, and the concurrent creation of more housing given increases in the human population in the future; (2) Housing and spatial requirements. Following on from the extra requirements for human housing given increases in human population, the critical issue of spatial requirements for this housing will be addressed; (3) Housing and net zero. The third section of this entry examines the possibility of housing in the Anthropocene reaching net zero and thus not contributing further to climate change. For the purposes of this entry, a time ceiling of 2050 will constrain each section, and limit the possibility of this entry becoming embroiled in overly speculative science fiction. (shrink)

ISBN 9781771136129.[End Page 280]The End of This World: Climate Justice in So-Called Canada by Angele Alook, Emily Eaton, David Gray-Donald, Joël (...) Laforest, Crystal Lameman, and Bronwen Tucker is both an imagining of a utopic, fossil-fuel-free world and a spirited call to action. Written in plain language and aimed at a wide audience, the book examines contemporary so-called Canada through an indigenous-centered,1 decolonial lens and frames the current climate crisis that we are in as one of relationship failure. The authors state: "We believe it is important for a just transition discussions to be accessible to all audiences because, fundamentally, what we're talking about in this book is repairing relationships. Repairing relationships with each other and with the land" (13). Key to repairing this relationship is putting indigenous rights and sovereignty at the center of any proposal or policy, instead of appearing as an add-on or afterthought. As the authors lead us through their plan for a just energy transition, they assert that any change, any movement, and any economic strategy that does not assert indigenous rights is not only "greening theft," it is also doomed to fail (7).The book is organized into two parts. The first part consists of the introduction and the first two chapters, where the authors outline broken promises and political and private decisions that have led to the current climate crisis in so-called Canada. The second half then outlines indigenous-informed solutions and possible paths forward, with the most concrete and "winnable" strategies in the last two chapters (153). The End of This World is a collaborative piece, written in one voice, while the individual authors' voices can be heard through various examples and anecdotes given throughout the book.In the first half of the volume, they lay out the rise and reliance on fossil fuels, the ongoing empowerment of the industry, and the swaths of broken promises the Canadian government has made since public concern for climate has been on the rise. The authors focus on two dynamics that they believe are the worst contributors to this crisis in so-called Canada: "the violation of indigenous people's inherent rights and sovereignty, and the fossil fuel economy that relies on this violation" (11). This is done by tracing the sordid history of indigenous-settler relations through official documents such as the [End Page 281] Indian Act and the residential school system, which systematically destroyed traditional indigenous relationships with each other and the land and replaced them with patriarchal capitalist colonial hierarchies. The authors argue that this destruction, along with the forced removal of indigenous people from their lands, effectively brought about an apocalypse, the aftereffects of which indigenous people across all of so-called Canada are still dealing with. This is an incredibly effective rhetorical strategy, pulling on the popular cultural imagination of the apocalypse and reframing the settlers' view of this world as an indigenous dystopia.The authors then lay out how the official policies and privatization of the industry by the Canadian state laid the groundwork for weakening resistance against fossil fuel projects on traditional indigenous territories, and for stripping the lands of resources and further alienating all people from their relationships with the land. They point out that when indigenous mobilization was finally recognized in the 1970s and 1980s, a swell of popular support from unions, labor activists, and environmentalists pushed back against rampant development and extraction. However, instead of strict regulation and limitation, the authors make it clear how the government and industry simply switched from climate denialism to "climate delayism," using terms like "sustainable development," "net zero goals," and "carbon neutrality" to push responsibility to the future and make no real changes, all while actually increasing development and projects in the industry.The greatest strength of this section is how...

In this article we address the so-called argument of «individual causal inefficacy» (ICI), according to which CO2-emission-generating actions are morally neutral with regards to climate change, in so far as, taken in their singularity, they are neither sufficient nor necessary to cause climate change. In the first part, we address the main substantive objection to ICI: if a single emission, analysed in isolation, does not cause any disutility, it is impossible to explain why climate change (which is the result of (...) a sum of emissions) is the source of an enormous disutility; thus, ICI should be rejected in so far as it leads to a conclusion that is logically inconsistent. We argue, contrary to this, that it is possible to hold together ICI and individual moral responsibility for climate change, given the characteristics of the natural carbon cycle and of net-zero emissions. In the second part, accordingly, we propose a theory of individual responsibility for climate change which is based on the distinction between individual and collective freedom to emit, compatibly with a given mitigation target. This theory allows us to maintain that there exists a moral duty to reduce individual emissions, without having to demonstrate the fallacy of ICI. This duty is based on distributive reasons, which can prescind from the direct causal relationship between individual polluting actions and climate damage. (shrink)

In this paper, I am concerned with how healthcare systems ought to transition away from the greenhouse gas emissions that they have historically relied on to provide care. I address two questions in relation to this issue. The first is what emissions target should healthcare systems adopt? Second, is how should the burdens of mitigation be shared fairly in light of that target? I argue that sufficientarianism offers an attractive way to answer both of these questions because it is better (...) situated to strike the right balance between healthcare benefits and the costs of mitigation than rivals. Sufficiency describes the view that what is important from the perspective of distributive justice is that individuals have enough. I argue that this ideal can be used to set a threshold of enough health from which an emissions threshold can be set. Once an emissions threshold is in place, this can be used to demarcate permissible from impermissible emissions in healthcare. In turn, the emissions threshold provides guidance on which emissions are liable to mitigation and when it would be fair for healthcare to shoulder the associated burdens. Permissible emissions, on the other hand, are necessary to secure sufficiency and so healthcare's mitigation responsibilities should be altered in light of this. I also discuss various alternative methods of setting an emissions target like net zero, zero emissions, emissions grandfathering and emissions egalitarianism. I point to several issues with these approaches. (shrink)

In 2020, the BSHS hosted two major online events, the first of their kind in our collective experience. The first, a Twitter conference, was planned and accomplished before COVID-19 had quite been established as a serious global issue. The conference was planned, rather, as an innovation in travel-free conferencing, something that has been on the BSHS agenda since the IPCC report of 2018, calling for net-zero-carbon activity in all areas by 2050. As we discussed the Twitter conference, and watched (...) the amazing energy, intellect and resourcefulness of its planners and hosts, we quickly saw that online delivery offered other advantages too – chiefly, wider participation. The pandemic offered the society a chance to take these lessons very boldly into the most important event of our scholarly calendar, which usually takes the form of an in-person annual conference, but this time was executed as an online festival.

Notions such as śūnyatā, catuṣkoṭi, and Indra's net, which figure prominently in Buddhist philosophy, are difficult to readily accommodate within our ordinary thinking about everyday objects. Famous Buddhist scholar Nāgārjuna considered two levels of reality: one called conventional reality, and the other ultimate reality. Within this framework, śūnyatā refers to the claim that at the ultimate level objects are devoid of essence or "intrinsic properties", but are interdependent by virtue of their relations to other objects. Catuṣkoṭi refers to the claim (...) that four truth values, including contradiction, are admissible in reasoning. Indra's net refers to the claim that every part of a whole is reflective of the whole. Here we present category theoretic constructions that are reminiscent of these Buddhist concepts. The universal mapping property definition of mathematical objects, wherein objects of a universe of discourse are defined not in terms of their content, but in terms of their relations to all objects of the universe is reminiscent of śūnyatā. The objective logic of perception, with perception modeled as [a category of] two sequential processes (sensation followed by interpretation), and with its truth value object of four truth values, is reminiscent of the Buddhist logic of catuṣkoṭi. The category of categories, wherein every category has a subcategory of sets with zero structure within which every category can be modeled, is reminiscent of Indra's net. Our thorough elaboration of the parallels between Buddhist philosophy and category theory can facilitate better understanding of Buddhist philosophy, and bring out the broader philosophical import of category theory beyond mathematics.

The deposit insurance makes the value of deposits independent from the behavior of other depositors or from the value of bank assets. Its existence induces a moral hazard which might threaten the stability of the banking system. The efficiency of the DI depends on the control of moral hazard, which means the agents’ responsibilisation, depositors included. There is a conflict between the DI principles and the present propositions improving this mechanism.The possible solutions in order to solve this paradox are the (...) restriction of the insurance coverage only for the demand deposits and the implementation of the double liability for the bank shareholders.The demand deposits insurance eliminates the incentive to bank runs caused by the fear of lack of liquidity, whereas the term deposits are exposed to losses which reduce the moral hazard induced by the demand deposit insurance.The double liability forces the shareholders of the defaulting banks to make supplementary payments limited to the nominal value of the owned shares. This combines the advantages of the limited liability and the unlimited liability.The efficiency of both propositions implies the enforcement of a closure rule of the banks whose net worth is close to zero.La garantie des dépôts rend la valeur des dépôts indépendante du comportement des autres déposa- nts ou de la valeur des actifs bancaires. Son instauration induit un aléa moral qui peut menacer la stabilité du système bancaire. L’efficacité de ce mécanisme dépend de la maîtrise de l’aléa moral. Cela suppose, entre autres, la responsabilisation des agents, y compris des déposants. Par conséquent, il existe un conflit entre le principe de la garantie des dépôts et les propositions courantes d’amélioration de ce dispositif.Les solutions envisagées dans cet article pour résoudre ce paradoxe sont la limitation de la garantie aux seuls dépôts à vue et l’instauration de la double responsabilité pour les actionnaires des banques.La garantie des dépôts à vue élimine l’incitation à la ruée due à la crainte de manque de liquidité, tandis que les dépôts à terme sont assortis d’une clause permettant à la banque de refuser tout retrait anticipé. Les titulaires des dépôts à terme s’exposent à des pertes, ce qui réduit l’aléa moral induit par la garantie des dépôts à vue.La double responsabilité oblige les actionnaires des banques défaillantes à effectuer des versements supplémentaires dans la limite de la valeur nominale des actions détenues. Cela réunit les avantages de la responsabilité limitée et de la responsabilité illimitée.L’efficacité des deux propositions suppose l’application d’une règle de fermeture des banques dont l’actif net avoisine zéro.

The National Health Service (NHS) was the first healthcare system globally to declare ambitions to become net carbon zero. To achieve this, a shift away from metered-dose inhalers which contain powerful greenhouse gases is necessary. Many patients can use dry powder inhalers which do not contain greenhouse gases and are equally effective at managing respiratory disease. This paper discusses the ethical issues that arise as the NHS attempts to mitigate climate change. Two ethical issues that pose a barrier to (...) moving away from metered-dose inhalers are considered: patients who decline an inhaler with a smaller carbon footprint and increased cost. I argue that while a patient is not morally justified in refusing a more environmentally sustainable inhaler due to the expected harms, a doctor may still prescribe a metered-dose inhaler if they believe that switching without consent might undermine trust or substantially worsen the patient’s health. Turning to cost, I argue that the imperative to combat climate change means the NHS should accept small increased financial costs for lower carbon inhalers, even though this provides no additional direct benefit for the patient. I then go on to consider the implications of the preceding analysis for policy and practice. I argue for a policy that minimises the impact of inhalers on the climate by advocating for a principle of environmental prescribing and explore decision-making in practice. While the arguments here pertain primarily to inhalers, the discussion has broader implications for debates around healthcare’s responsibility to be environmentally sustainable. (shrink)

This highly original book develops a systematic zero-net-profit comparative statics theory of the firm that challenges many widely held views in microeconomics. It builds a bridge between the marginalist long-run theory of the firm and Sraffian theory to create a unified theoretical framework that explains how firms react to exogenous shocks resulting in new equilibrium positions of the whole economy. The central message of the book is that too often economists expect more from the microeconomic laws of input demand (...) and output supply than they can really give. The authors show that the zero-net-profit condition requires a more articulated analysis that sometimes yields qualitative results contrary to those of familiar economic laws. Written for academic researchers and graduate students, the book will be of particular interest to those working on the microeconomics of industry equilibrium, comparative statics and Sraffian economics.

Wallace's contributions to biological thought tend to be overlooked or overly praised, neither of which produces a satisfactory assessment. Examples of the latter tendency are the recent expositions by Brackman and Brooks; although both books contain much worthwhile material, both are flawed. At critical points their theories fail to measure up, Brackman's because of his misinterpretations of events in the month of June 1858, and Brooks's Darwin's September 5 letter to Gray could, and probably did, represent an ordering of his (...) ideas in response to a felt challenge.A fruitful way to characterize the relationship between Darwin and Wallace may be found in terms of game theory. Most scholars look upon the relationship as a zero-sum game, with a winner and a loser, the matter of priority being considered as a “single event.” Another approach would be to look upon it as a non-zero-sum game with each man influencing the other. In this case, the productivity of one is stimulated by the contributions of the other, resulting in a net gain in knowledge overall, and both men become winners, or codiscoverers. This approach is possible if Wallace's contributions to the theory of evolution by means of natural selection are recognized. (shrink)

Using the concept of purposeful action, I define the necessary and sufficient aspects of any property. These qualities are derived though noticing that property is those things which are the object of a set of past, present, and future actions of individuals. The result is that property is the result of a change in the physical world which lends itself to control and is expected to grant a future value to the actor. By deconstruction, these qualities are used to show (...) that aggression upon another actor is equivalent to a property claim in that other actor, enforcement of a property claim may involve an aggression, and conflicting aggressions may only be compared subjectively. Thus the novel concept of net coercion is introduced to delineate which actors are making an over-reaching property claim. This incorporates the common term of aggression as used by modern libertarian theorists, but allows for a further analysis when there are conflicts of possible or perceived aggressions; certainly attempting to minimize the net coercion of a system of actors is equivalent to the special case of striving for zero-aggression. After establishing the value-free concepts that entail property regimes I define the seeking of justice as trying to minimize the net coercion of any system. From this single necessary definition of justice, a number of problems are analyzed including the stereotypical commons, a construction equivalent to hostile encirclement, and claims of property in intellectual creations. The ultimate conclusion of this analysis is that property regimes with a positive net coercion are unjust and equivalent to property claims in the individual actors subject to the more aggressive actors, in essence, that they are the chattel slaves of the dominant actors in proportion to the amount of net coercion used against them. From these foundations, a philosophical system by which to analyze particular property claims is created and a suggestion of how law and economics should treat property claims is implicit. (shrink)

Substrate cycles are ubiquitous structures of the cellular metabolism (e.g. Krebs cycle, fatty acids -oxydation cycles, etc... ). Moiety-conserved cycles (e.g. adenine nucleotides and NADH/NAD, etc...) are also important.The role played by such cycles in the metabolism and its regulation is not clearly understood so far. However, it was shown that these cycles can generate multistationarity (bistability), irreversible transitions, enhancement of sensitivity, temporal oscillations and chaotic motions (Hervagault & Canu, 1987; Hervagault & Cimino, 1989; Reich & Sel'kov, 1981; Ricard & (...) Soulié, 1982). Fig. 1: Scheme of the open binary substrate cycle under study. The substrate S is converted into P with a net rate v2. Substrate P is converted in turn into S with a net rate v3. Step v2 is inhibited by excess of the substrate, S. In addition, the cycle operates under open conditions, that is zero-order input of S at rates \ga0(v1) and first order outputs of S and P at rates \gaS and \gaP(v4), respectively. (shrink)

Vacuum radiation causes a particle to make a random walk about its dynamical trajectory. In this random walk the root mean square change in spatial coordinate is proportional to t 1/2, and the fractional changes in momentum and energy are proportional to t −1/2, where t is time. Thus the exchange of energy and momentum between a particle and the vacuum tends to zero over time. At the end of a mean free path the fractional change in momentum of (...) a particle in a gas is very small. However, at the end of the mean free path each particle undergoes an interaction that magnifies the preceding change, and the net result is that the momentum distribution of the particles in a gas is randomized in a few collision times. In this way the random action of vacuum radiation and its subsequent magnification by molecular interaction produces entropy increase. This process justifies the assumption of molecular chaos used in the Boltzmann transport equation. (shrink)

The general aim of this thesis is to present and analyse traffic safety from an ethical perspective and to explore some conceptual and normative aspects of moral responsibility. Paper I presents eight ethical problem areas that should be further analysed in relation to traffic safety. Paper II is focused on the question of who is responsible for traffic safety, taking the distribution of responsibility adopted through the Swedish policy called Vision Zero as its starting point. It is argued that (...) a distinction should be made between backwardlooking and forward-looking responsibility and that Vision Zero should be understood in terms of this distinction. Paper III discusses responsibility ascriptions in relation to public health problems like obesity and lung cancer. It is argued that what makes discussions about who is responsible for such problems complicated is that we have two aims when ascribing responsibility to someone. First, we want responsibility ascriptions to be fair and morally justified. Second, we also want to achieve progress and solve problems through ascribing responsibility to someone. It is argued that the two aims influence debates concerning who is responsible for problems like obesity and lung cancer and that we should attempt at striking a balance that is both perceived as fair and that is efficient. Paper IV discusses two potential arguments against the suggestion that alcohol interlocks should be mandatory in all cars, namely 1) that it displaces the responsibility of individual drivers, and 2) that it constitutes a paternalistic interference with drivers. The first objection is found unconvincing, while the second only has limited bite and may be neutralized if paternalism is accepted for the sake of greater net liberty. It is argued that if technological development can make mandatory interlocks cost-efficient, the policy seems a commendable public health measure. In Paper V, the question discussed is to what extent individuals should be ascribed moral responsibility for the environmentally damaging consequences of their actions. It is argued that responsibility depends on the reasonableness of the alternatives open to an individual when acting. The lack of reasonable alternatives should reduce the degree of individual responsibility. (shrink)

It is shown that the following three common understandings of Newton’s laws of motion do not hold for systems of infinitely many components. First, Newton’s third law, or the law of action and reaction, is universally believed to imply that the total sum of internal forces in a system is always zero. Several examples are presented to show that this belief fails to hold for infinite systems. Second, two of these examples are of an infinitely divisible continuous body with (...) finite mass and volume such that the sum of all the internal forces in the body is not zero and the body accelerates due to this non-null net internal force. So the two examples also demonstrate the breakdown of the common understanding that according to Newton’s laws a body under no external force does not accelerate. Finally, these examples also make it clear that the expression ‘impressed force’ in Newton’s formulations of his first and second laws should be understood not as ‘external force’ but as ‘exerted force’ which is the sum of all the internal and external forces acting on a given body, if the body is infinitely divisible.

The electric field of an orbiting charge or electron observed in the rotating frame takes on a circular trajectory with a maximum radius of \. The resultant extended electromagnetic structure is used to derive the spin–orbit energy of the orbiting electron. A surprising result of the derived expression is that the orbital velocity has a specific value ) in close agreement ) with the experimentally determined value for the fine structure constant ). Furthermore, the derived spin–orbit expression does not include (...) a g-factor ) which means that the Larmor and Thomas precessions are equal and opposite, resulting in zero net precession in the lab frame. These results suggest that the quantised fine structure constant and by extension Planck’s constant, are a natural extension of classical electromagnetism and conservation of energy in a rotating frame.

We address the most fundamental yet routinely ignored issue in economics today: that of distributive impact of the monetary system on the real economy. By re-examining the logical implications of token re-presentation of value and Irving Fisher’s theory of exchange, we argue that producers of value incur incidental expropriation of wealth associated with the deflationary effect that new value supply has on the purchasing power of money. In order to remedy the alleged inequity we propose a value-added negative tax (VANT) (...) based on net individual contribution to the economic output, which is structured as a negative tax function geared to profits derived from eligible productive activities in consideration of their estimated deflationary impact. We show that an adequately optimised VANT can be non-inflationary and have zero net cost to the public. Furthermore, economic output stands to improve due to direct incentivisation of value creation, making the proposed scheme not only politically feasible but economically desirable. The proposal advances the principle of ‘fair money’, where all forms of economic value are attributed to their rightful owners prior to any positive taxation. (shrink)

Notions such as Sunyata, Catuskoti, and Indra's Net, which figure prominently in Buddhist philosophy, are difficult to readily accommodate within our ordinary thinking about everyday objects. Famous Buddhist scholar Nagarjuna considered two levels of reality: one called conventional reality and the other ultimate reality. Within this framework, Sunyata refers to the claim that at the ultimate level objects are devoid of essence or "intrinsic properties", but are interdependent by virtue of their relations to other objects. Catuskoti refers to the claim (...) that four truth values, along with contradiction, are admissible in reasoning. Indra's Net refers to the claim that every part of a whole is reflective of the whole. Here we present category theoretic constructions which are reminiscent of these Buddhist concepts. The universal mapping property definition of mathematical objects, wherein objects of a universe of discourse are defined not in terms of their content, but in terms of their relations to all objects of the universe is reminiscent of Sunyata. The objective logic of perception, with perception modeled as [a category of] two sequential processes (sensation followed by interpretation), and with its truth value object of four truth values, is reminiscent of the Buddhist logic of Catuskoti. The category of categories, wherein every category has a subcategory of sets with zero structure within which every category can be modeled, is reminiscent of Indra's Net. Our thorough elaboration of the parallels between Buddhist philosophy and category theory can facilitate better understanding of Buddhist philosophy, and bring out the broader philosophical import of category theory beyond mathematics.

Voor de taalgebruiker spreekt taal vanzelf, maar de taalonderzoeker staat voor raadsels. Woordvormen lijken in niets op hun betekenis. En taalconstructies lijken onlogisch in elkaar te zitten. Toch kunnen we in een enkele zin onze bedoelingen tot in de subtielste nuances duidelijk maken. We hebben geen toegang tot het bewustzijn van de Ander maar kunnen desondanks gedachten met elkaar uitwisselen. We kunnen de werkelijkheid met elkaar bespreken en fictieve werelden met elkaar delen alsof ze toch ergens buiten onszelf bestaan. De (...) taalgebruiker heeft er allemaal geen moeite mee. In De magie van taal brengt Net Koene stap voor stap in kaart wat zich in ons hoofd afspeelt wanneer we naar de Ander luisteren. Ze isoleert taalvormen, woorden, constructies, toonhoogte- en ritmekenmerken die we als informatief herkennen in wat de Ander zegt. Ze laat zien hoe al die vormen systematisch hun eigen bijdrage leveren aan onze voorstelling van waar de Ander het over heeft. De auteur toont deze processen vanuit een denkbeeldig alwetend perspectief, in dit boek Omega genoemd. Binnen dit theoretische kader legt ze per hypothese verband tussen wat in het bewustzijn opkomt en de machinerie van het brein: hoe vormt de wereld van onze zintuigen zich, hoe komt ons voorstellingsvermogen tot stand, hoe transformeert de zintuiglijke wereld in een bespreekbare wereld? En vooral: hoe werkt het dat we de inhoud van ons bewustzijn op dat van de Ander kunnen afstemmen? (shrink)

Jeff Bernard was a distinguished semiotician, always au courant with the main accomplishments in the field. Although Jeff himself had specialized in socio-semiotics, his architectural training and his artistic youth had lent him a really open mind, able to comprehend almost everything.Jeff Bernard was also an excellent administrator. He and Gloria organized countless international conferences, most of them based in Vienna (at the Institute for Socio-Semiotic Studies Jeff was the director of ), but also in other places in Austria, Germany, (...) Italy. All of them were a success. Jeff ran the ISSS almost single-handed. He edited books (he published three of mine, among many, many others), anthologies, semiotic journals. He knew how to raise funding, of which the whole semiotic community benefitted. In 2003, he acted as my “impresario”, as he jokingly said, and organized a lecturing tour through Central Europe for me.Jeff was also a wonderful host; he considered his guests as part of the family and treated them accordingly. Many were the times when he picked me up from one Viennese railway station or the other, or when he drove me there, when I stopped in Vienna, to or from other places. It was owing to Jeff and Gloria that I discovered Grinzig, Baden, and various other cozy places in and around Vienna. Last but not least, it was also due to Jeff and Gloria that I discovered the charm of many Viennese restaurants.Jeff was kind and generous, elegant and discreet. He helped quite a lot of semioticians to forward their careers, and more important still, he did it unobtrusively. Jeff was also a likeable person, with an entertaining conversation and a fine sense of humor.“I am a Feminist”, Jeff once said. (For the sake of historical accuracy, it was in September 1997, round a dinner table at the Early-Fall School of Semiotics, thenheld in Bankya, Bulgaria). And he further expanded: “Otherwise, we couldn’t be living with Gloria. And my life would be pretty difficult, virtually surrounded as I am by so many professional women. But they all think I am a Feminist, and they are happy to work for my benefit. So I sit at my desk in Vienna, and my women colleagues from all over the world send me contributions for this and that, come over to participate in conferences, etc. It pays being a Feminist”.“Ich bin ein Berliner”, said Jeff on another occasion. For historical accuracy, it was in September 2003, during the conference celebrating his 60th birthday, in answer to a remark made by Roland Posner. It seemed a humorous statement, and everybody smiled. But I think this was true in spirit. These few lines, as well as (I suppose) those written by other colleagues who have contributed to the present issue, are meant to illustrate this self-definition. Jeff had always sympathized with the less privileged people everywhere. (shrink)
