First, with respect to our personal relationship to fossil fuels, this chapter introduces arguments about whether we should or even can address our own usage of fossil fuels. This involves determining whether offsetting emissions is morally required and practically possible. Second, with respect to our relationship with fossil fuels at the national level, it discusses forms of local resistance, especially divestment and pipeline protesting. Finally, with respect to our relationship with fossil fuels (...) at the international level, it considers two types of policy. On the one hand, some have argued that we should stop most trade in oil, on the basis that most oil that is traded is not subject to the control of citizens. On the other hand, some have argued that we should price the costs of fossil fuels so that there are market incentives to avoid digging them out of the ground. (shrink)

Gas will increasingly be seen as the fossil fuel of choice, especially when considering environmental impacts. Natural gas is the chance for Serbia for sustainable development and with its intensive consumption in the XXI century to conciliate the 4Es (Energy, Economy, Efficiency and Environment). In this paper we will compare the impact of different fossil fuels used for domestic heating with a special emphasis on natural gas. Some other causes of climate changes will be also discussed such (...) as the Milanković astronomical cycles. These factors will be compared with climate changes caused by the consumption of fossil fuels. (shrink)

As the devastation of climate change makes the need to decarbonise clearer by the day, countries face the question of what to do with their old fossil fuel infrastructure. While some environmental activists have taken to sabotaging the carbon economy on the back of its emissions in the Global North, the picture is different in oil-producing countries of the Global South, where energy infrastructure has fed communities for decades. There, the emphasis is placed on memory and institutionalisation.

This chapter constructs the argument that corporate and political policies known to accelerate anthropogenic global warming, and subsequent climate change, constitute crimes against humanity—predicated on failures to avoid reasonably foreseeable threats to sustained human existence. Given the moral gravity of crimes against humanity it follows that financial divestment is ethically obligatory for institutions wishing to avoid moral association. The moral case for fossil fuel divestment, in the wake of such crimes, derives from (a) the ethical implications of negative responsibility, (...) or what constitutes culpability by omission; (b) institutional collaboration based upon immediate financial interests tied to climate inaction; and (c) institutional complicity derived from financial support of corporate behaviors that hasten global warming. Possible objections are examined and refuted. (shrink)

This paper reviews current initiatives to establish carbon offset forests in suburban and peri-urban environments. While moments of density occur within urban territories the general spatial condition is one of fragmented and patchy networks made up of a heterogeneous mix of residential enclaves, industrial parks, waste sites, infrastructure easements interspersed with forests, agriculture, leftover voids and overlooked open space. These overlooked open spaces have the potential to form a new green urban structure of carbon offset forests as cities respond to (...) the carbon economy. Furthermore such urban spaces are not likely to diminish over time as cities are not only growing larger but are becoming more dispersed according to recent World Bank reports. This strong trend is not limited to developed or developing cities but is a worldwide phenomenon. In the future, policy incentives for carbon sequestration will drive land use change in rural and urban areas alike. The paper documents projects in Blacktown City Council in Western Sydney.

Many governments are failing to act sufficiently strongly on climate change. Given this, what should motivated affluent individuals in high-consumption societies do? This paper argues that social norms are a particularly valuable target for individual climate action. Within norm-promotion, the paper makes the case for a focus on anti-fossil fuel norms specifically. Section 1 outlines gaps in the existing literature on individuals’ climate change obligations. Section 2 characterises social norms. Section 3 provides seven reasons why social norms are a (...) particularly worthy target for individual climate actors. Section 4 asks which social norms individuals should emphasise, arguing that anti-fossil fuel norms have advantages over emissions reduction and offsetting norms. Section 5 outlines the pathways and mechanisms individuals might exploit to promote anti-fossil fuel norms. (shrink)

The military-industrial complex, military operations, and wars are major contributors to exacerbating both climate change and biodiversity crises. However, their environmental impacts are often shadowed due to national security reasons. The current paper aims to go through the devastating impacts of military operations and wars on climate change and biodiversity loss and challenges that hinder the inclusion of military-related activities into environmental crisis mitigation efforts. The information blind spot induced by concerns about national security reasons jeopardizes the efforts to involve (...) the military-industrial complex and military operations in the global climate and biodiversity agendas. Besides that, many military-related challenges, such as specificity of operational requirements and lifecycles, dependence on fossil fuels, complex supply change, inadequate civilian technologies and innovations, and requirements of structural changes, can hinder emission reduction. Meanwhile, wars and conflicts not only threaten to drain all human and material resources available to tackle environmental problems but also inflict long-lasting destructions, pains, and trauma that can lead to hatred and distrust among nations and parties. With the rising hatred and distrust, global agreement and commitment to address climate change and biodiversity will hardly be achieved. Thus, promoting peace is the humanistic and planetary conscience. (shrink)

Many of the items that humans consume are produced in ways that involve serious harms to persons. Familiar examples include the harms involved in the extraction and trade of conflict minerals (e.g. coltan, diamonds), the acquisition and import of non- fair trade produce (e.g. coffee, chocolate, bananas, rice), and the manufacture of goods in sweatshops (e.g. clothing, sporting equipment). In addition, consumption of certain goods (significantly fossil fuels and the products of the agricultural industry) involves harm to the (...) environment, to future persons, and to current persons in low-lying and developing countries, by way of their impacts on climate change. When it comes to such large-scale harms, it's easy for the individual to feel helpless. Even if she sincerely wishes things were otherwise, she may wonder what she could possibly do to make them so. In this paper I briefly explore several promising avenues for generating duties in individuals to consume ethically, and develop one in particular: that an individual ought to signal her commitments to others, as a first step in collectivizing to act against unjust global labour practices.

The depletion of fossil fuels, coupled with the growing awareness of the impact of fossil fuel consumption on the global environment, has spurred research activities focused on alternative (or recycled energy). Besides, the demand for energy and related services to meet people's economic and social development, welfare and health is also increasing daily. Therefore, renewable energy is an excellent approach to mitigate climate change and meet the sustainable energy needs of present and future generations future.

This study addresses the issue of the climate change crisis, which has caused many dangerous phenomena for humanity, due to greenhouse gas emissions that cause global warming, drought, and others. The most important reason for this phenomenon that worries the world is human behavior, especially the use of fossil fuels. The largest contributor to this behavior is international oil companies, which export oil to all countries of the world. The most important major source of oil is the Middle (...) East. Oil companies operating there play an essential role in the growth of the oil industry around the world, which has caused a significant increase in the level of global greenhouse gas emissions. The study reviews the practices undertaken by national companies in the Middle East and their attempts to mitigate the effects of climate change by adopting environmental sustainability policies. This study aims to evaluate national oil companies operating in the Middle East region to determine the level of companies’ ability to contribute to mitigating the effects of climate change. The study reached many results and identified companies with high environmental performance and positive methods that can be disseminated to achieve the required environmental sustainability and implement sustainable development practices, and how to benefit from social marketing and direct it towards enhancing awareness of climate risks.

The past years have witnessed a growing awareness of the role of institutions of knowledge production in reproducing the global climate crisis, from research funded by fossil fuel companies to the role of mainstream economics in fuelling the idea of growth. This essay argues that rethinking knowledge production for post-carbon futures requires engaging with the co-determination of modes of knowing and modes of governing. The ways in which knowledge production is embedded in networks of global capitalism shapes how we (...) (can) think about the future. The essay argues for an attentivity to the material and infrastructural sides of knowledge production, which will enable us to re-think transition to post-carbon futures in ways that recognize the deep structural, spatial and social inequalities underpinning knowledge production.

In this article, we claim that recent developments in climate science and renewable energy should prompt a reframing of debates surrounding climate change mitigation. Taken together, we argue that these developments suggest (1) global climate collapse in this century is a non-negligible risk, (2) mitigation offers substantial benefits to current generations, and (3) mitigation by some can generate social tipping dynamics that could ultimately make renewables cheaper than fossil fuels. We explain how these claims undermine familiar framings of (...) climate change, wherein mitigation is understood as self-sacrifice that individuals and governments must be morally persuaded or incentivized to undertake.

The global production of radioactive wastes is expected to increase in the coming years as more countries have resorted to adopting nuclear power to decrease their reliance on fossil-fuel-generated energy. Discoveries of remediation methods that can remove radionuclides from radioactive wastes, including those discharged to the environment, are therefore vital to reduce risks-upon-exposure radionuclides posed to humans and wildlife. Among various remediation approaches available, microbe-mediated radionuclide remediation have limited reviews regarding their advances. This review provides an overview of the (...) sources and existing classification of radioactive wastes, followed by a brief introduction to existing radionuclide remediation (physical, chemical, and electrochemical) approaches. Microbe-mediated radionuclide remediation (bacterial, myco-, and phycoremediation) is then extensively discussed. Bacterial remediation involves biological processes like bioreduction, biosorption, and bioprecipitation. Bioreduction involves the reduction of water-soluble, mobile radionuclides to water-insoluble, immobile lower oxidation states by ferric iron-reducing, sulfate-reducing, and certain extremophilic bacteria, and in situ remediation has become possible by adding electron donors to contaminated waters to enrich indigenous iron- and sulfate-reducing bacteria populations. In biosorption, radionuclides are associated with functional groups on the microbial cell surface, followed by getting reduced to immobilized forms or precipitated intracellularly or extracellularly. Myco- and phycoremediation often involve processes like biosorption and bioaccumulation, where the former is influenced by pH and cell concentration. A Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis on microbial remediation is also performed. It is suggested that two research directions: genetic engineering of radiation-resistant microorganisms and co-application of microbe-mediated remediation with other remediation methods could potentially result in the discovery of in situ or ex situ microbe-involving radioactive waste remediation applications with high practicability. Finally, a comparison between the strengths and weaknesses of each approach is provided. (shrink)

Vấn đề môi trường là trọng tâm của các cuộc thảo luận chính trị trong những năm gần đây, với việc các nhà lãnh đạo trên toàn thế giới thực hiện các biện pháp chống biến đổi khí hậu và giảm phát thải khí nhà kính. Để theo đuổi mục tiêu bảo vệ môi trường và giảm thiểu biến đổi khí hậu, Tổng thống Joe Biden đã thực hiện một loạt hành động nhằm giảm phát thải khí nhà kính và (...) hạn chế sự phụ thuộc của chúng ta vào nhiên liệu hóa thạch. Trong số các sáng kiến này, quyết định của Tổng thống Biden về việc đóng cửa Đường ống Keystone XL, hạn chế hoạt động khoan dầu ở một số khu vực nhất định và cấm cấp phép khai thác dầu khí mới trên các vùng đất và vùng biển công cộng là một động thái quan trọng. Tuy nhiên, những chính sách này đã gây ra cả sự ủng hộ lẫn tranh cãi.

[Newspaper opinion] To give carbon storage sites the greatest chance of success, it makes sense to develop them in places where the geology has been thoroughly explored and where there is lots of relevant expertise. This would imply pumping carbon into underground storage sites in northern Europe, the Middle East and the US, where companies have spent centuries looking for and extracting fossil fuels. On the other hand, it might be important to develop storage sites in economies where (...) the current and future demand for carbon capture and storage is greatest. The regions with the best prospects are not often those with the greatest expected need. [Open access]. (shrink)

This study focuses on implementing electric vehicles (EVs) in developing countries where energy production is mainly based on fossil fuels. Although for these countries the environmental short-run benefits of the EVs cannot offset the short-run costs, it may still be the best option to implement the EVs as soon as possible. Hence, it is necessary to evaluate the alternatives to introducing EVs to the market due to the environmental concerns that created an opportunity for some developing countries to (...) catch up with the international competition. Therefore, we develop a case scenario to explore the decision-making process in implementing the EVs with three alter natives and twelve criteria. We solve the decision-making problem by using Type-2 neutrosophic numbers (T2NNs) based on the RAFSI (Ranking of Alternatives through Functional mapping of criterion sub-intervals into a Single Interval) method. The proposed model combines the advantages of the RAFSI technique, and it applies T2NNs to address the uncertainties. The results show that the alternatives that may suspend the implementation of the EVs are inferior. Direct implementation of EVs is prioritized. The policy implications of the results are discussed in the study. (shrink)

In the unfolding debate on the prospects, challenges and viability of the imminent transition towards a ‘Bio-Based Society’ or ‘Bio-based Economy’—i.e. the replacement of fossil fuels by biomass as a basic resource for the production of energy, materials and food, ‘big’ concepts tend to play an important role, such as, for instance, ‘sustainability’, ‘global justice’ and ‘naturalness’. The latter concept is, perhaps, the most challenging and intriguing one. In public debates concerning biotechnological interactions with the natural environment, the (...) use of terms such as ‘nature’ and ‘naturalness’ is both inevitable and hazardous . Indeed, various conflicting interpretations of naturalness play a role on both sides of the current debate. This paper aims to analyse and critically assess the role of ‘nature-speak’ in the BBS transition. We will begin with a concise overview of the vicissitudes of the nature-concept so far, focussing on how modern science and technology have challenged and affected our understanding of what nature is. Subsequently, we describe how ‘naturalness’ functions in the unfolding BBS debate. Finally, we will focus on a particular case study, namely the production of rubber with the help of natural latex coming from dandelion plants rather than from rubber trees. On the one hand, this is presented as a more natural and nature-friendly way of producing rubber. On the other hand, it is a sophisticated process, involving high technology and primarily focussed on competitiveness on the global market. To what extent or in what sense can dandelion latex be regarded as more natural? And what can we learn from this case study when it comes to addressing naturalness in the broader conceptual and bio-political arena? (shrink)

Air pollutants pose a threat to biodiversity throughout the world. This study was conducted to evaluate atmospheric element accumulation in Isparta city, including Gölcük Nature Park, located in the Western Mediterranean Region of Turkey. It is aimed to determine the air quality and potential pollutant sources in the region through lichen biomonitoring. Specimens of the epiphytic foliose lichen Physcia aipolia (Erh. ex Humb.) Fürnr. were sampled from 14 sites in the study area and analyzed by ICP-MS with reference material in (...) order to detect 11 trace elements; Al, As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, V, and Zn. The spatial distribution of these airborne elements in the study area was mapped. The results showed that the elemental sequence in terms of average concentrations measured was as follows: Ni >Cr >V >Fe >As >Al >Zn >Cu> >Cd >Mn >Pb. The results of cluster analyses of the elemental data indicated that the 3 major contaminants in the urban area were Cr, Ni, and V, probably due to the extensive use of coal in heating facilities and gasoline in vehicles. P. aipolia specimens accumulated maximal concentrations of As, Cr, Fe, Ni, and V in the northern and the southeastern localities surrounding the city, while Cd, Pb were most abundant in the eastern edge of Gölcük Nature Park. The pollution in Isparta city with heavy metal is worse than expected, mostly due to the extensive use of coal as fossil fuel. In addition, it seems to be associated with the city's topographic and climatic characteristics, e.g. inversion effects. (shrink)

India dropped its target of 500 GW of renewable energy capacity fossil fuel sources by 2030. Its responsibilities the United Nations Framework Convention Climate Change [UNFCCC],and reducing radiations by one billion tonnes by the end of the decade at the COP26 conference, held in Glasgow in November 2022. Researchers are continually searching for inexhaustible and reasonable energy sources. Solar energy is one of the greenest sources of energy and is also one of the cleanest. The most important factor in (...) using solar energy is the location of the solar power plant. The main objective of this study is to find the best location for a new solar power plant in a specific region called Bundelkhand region of Uttar Pradesh in India. Here we offer an extension of ELECTRE III method as two-phase Pythagorean neutrosophic elimination and choice translating reality PN-ELECTRE-III) method to adapt with fuzzy, ambiguous, unsure, and indeterminate criteria. The Pythagorean neutrosophic numbers [PNNs] used by the group decision support system of PN-ELECTRE III to measure performance of the alternatives. The options are entirely outclassed in the subsequent stage in view of the past stage's evaluations of them. By defining PNN we describe the technique of indifference threshold functions, preference treshold and veto threshold functions, which provide a more stable basis to drop outranking relations. By calculating the concordance credibility, discordance credibility and net credibility degrees of each alternative, the ranking module of the PN-ELECTRE III approach is made simpler. In order to confirm the applicability of the strategy suggested in this paper, the location selection problem for solar plants is finaly solved. (shrink)

This paper focuses on the novel and leading innovations and investments into the new energy technologies. Energy issues, including sustainability, energy security and energy dependency are probably one of the most crucial and critical issues that humanity must face at the moment. Recent global challenges, such as climate change and the rise of the “green” energy (represented by the increasing deployment of the renewable energy sources (RES)), as well as distributed energy generation and platform energy markets (e.g. peer-to-peer (P2P) markets (...) for electricity) that were made possible thanks to the rise of Internet, social networks and sharing economy, all create a demand for the new energy technologies. The leaders in energy innovations, such as Tesla are becoming the true trendsetters who are marking the way for the humankind to go forward.We provide an overview of the innovative energy technologies that might change the energy market as we know it and discuss their outcomes and possible implications. Moreover, we contemplate the changes that might be caused by the ongoing transition from the fossil fuels to RES. Our results might be of some interests to researchers and stakeholders dealing with energy economics and policy. (shrink)

In recent times, limitations and adverse effects of fossil fuels have significantly attracted researchers' attention to green fuels worldwide, especially in developed nations. As a way of assessing this actualization of biorefineries establishment in developing nations, this report surveys the works done by various researches towards this great course in terms of promoting and gaining the attention of both government and private investors about the technical and economic feasibility of embracing the use of biofuels, a case of (...) bioethanol in Nigeria. Different classes of feedstocks were reviewed for the laboratory-scale, process scale-up, pilot plant, and techno-economic studies regarding ascertaining the technical and economic feasibility of local setup of a functional biorefinery in Nigeria, which would be beneficial environmentally and economically. The literature survey unveiled that the Bioethanol yield obtained from sugarcane-juice (72.7 %), banana-stems (84.0 %), and cassava (92.0 %) were found to be of highest potential amongst other sugar-based, lignocellulosic, and starch- based feedstock, respectively. The survey further unveils that the volume of process scale-up and economic feasibility studies does not correlate well with the laboratory-scale studies. The bulk of the research works on bioethanol has given preferential attention to laboratory studies. Only a few studies have looked into the commercialization (i.e., scale-up) of the laboratory findings and the economic implications. Presently, only sugarcane and a few cassavas are reported in the literature so far. It is, therefore, necessary for further studies to give attention to the investigation of the commercializing locally developed technologies and the exploration of their economic benefits. (shrink)

Abstract— According to studies, buildings use around 40% of the total energy consumption in the world. Most of this consumed energy comes from fossil fuel, one of the sources of environmental pollution. The Net Zero Energy Building (NZEB) is an alternative to this alarming pollution. With its reduced energy needs and renewable energy systems, a ZEB can return as much energy as it takes from the utility on an annual basis. Thus the main objective of this study is to (...) discuss the economical and friendly environmental renewable energy system integrated to building in Egypt to be (NZEB) economical by maximizing the renewable energy fraction and minimizing the greenhouse gases (GHG) emissions. The system consists of two renewable energy sources, comprising photovoltaic system, a wind turbine are considered for the proposed building under the study. By Utilizing the well-known Hybrid Optimization of Multiple Electric Renewables software to get the optimal configuration of a hybrid renewable energy system, based on the user inputs of loads, costs, technical details, solar and wind resources availability.

[Opinion] This aims to begin deliberation about investing in negative emissions technologies (NETs) by suggesting that the investment could be responsive to two particular values: need and efficiency—and that these values point us towards taking different actions. For negative emissions technologies, I suggest, we face a Need-Efficiency Tradeoff, i.e. a “NET effect”. This tradeoff also highlights several contrasts: responding to need focuses on regional and short-term moral considerations; responding to efficiency focuses on global and long-term moral considerations.

The current humans are the first ones to recognise that action is required on climate change, but the urgency makes us also possibly the last generation to be able to act before major threats are aggravated. I applaud the general message of an urgent call for action in Shue’s book but find that the brushstrokes used for identifying those responsible are a little too broad. The reason for this is twofold. Firstly, it is questionable as to how many of us (...) really know enough about the risks we are leaving future generations with. Secondly, discussion in terms of generations underplays the big differences between the responsibility of different groups of actors within them. (shrink)

Highlights: -/- • Breastfeeding and breastfeeding support can contribute to mitigating climate change. • Achieving global nutrition targets will save more emissions than fuel-switching. • Breastfeeding support programmes support a just transition. • This work can support the expansion of mitigation options in energy system models. -/- Abstract: -/- Renewable gas has been proposed as a solution to decarbonise industrial processes, specifically heat demand. As part of this effort, the breast-milk substitutes industry is proposing to use renewable gas as a (...) substitute for fossil natural gas. However, decarbonising the industrial processing of breast-milk substitutes can increase social license for these products, potentially undermining breastfeeding. World Health Organisation nutrition targets aim to increase exclusive breastfeeding to at least 50% globally by 2025 to improve maternal, infant, and young child health and nutrition. This target will have implications for the energy transition. A weakness of existing energy models is that demands for end-use products such as breast-milk substitutes are typically not considered explicitly. This paper develops an analytical framework for explicitly representing infant feeding methods in energy systems models. We compare the emissions saved in Ireland from decarbonising the industrial processing of breast-milk substitutes with renewable gas with the emissions saved by an increase in exclusive breastfeeding to 50% in both Ireland and a key export market, China. We demonstrate that the emissions saved from achieving the minimum global breastfeeding target are greater than when renewable gas is used to displace natural gas in the production of breast-milk substitutes in Ireland. We discuss the decarbonisation of breast-milk substitutes in relation to the principle of justice as non-maleficence, a principle based on the commitment to avoid harm, a novel application of a principle of justice. We conclude that breastfeeding support can be considered a demand-side measure for mitigating climate change by reducing the demand for energy services to produce breast-milk substitutes. A key recommendation is to position breastfeeding support as both a public health and a climate justice issue that is relevant for a just transition. The framework developed for this paper could be applied to support the inclusion of a wider range of mitigation options with social justice outcomes in energy system models. [Open access]. (shrink)

Scientific enterprise is a part and parcel of the contemporaneous to it general human cultural and, even more general, existential endeavor. Thus, the fundamental for us notion of evolution, in the modern sense of this characteristically Occidental term, appeared in the 19-th century, with its everything pervading, irreversible cultural and technological change and the existential turmoil. Similarly, a formerly relatively recherché word emergence, became a widely used scientific term only in the 20-th century, with its cultural, economical, political, and national (...) sagas of emergence and destruction played against a background of the universe emerging from the Big Bang and disappearing into its black holes, if not into its ultimate Big Collapse. Today, the rules of engagement in scientific emergence-evolution games, steadily spreading from natural to cognitive sciences, and beyond, are dominated by the 19-th century concept of natural selection which has inverted the time-arrow of the classical creationist dogma, with its rarely spelled out pessimistic implication that the life is moving from the highest biological organization to an entropic chaos. In its turn, the natural selection’s excessively contagious, “do-it-yourself” optimism might ultimately turn out to be its undoing : the natural selection conjecture, when transposed to such fields as linguistics from the strictly biological scene, with its times of engagement ranging from at most hundred years of life expectancy for an individual organism to at least millions and even billions of years for evolutionary processes to bring this or that organism to existence, becomes for the first time verifiable and even falsifiable. The present paper studies some implications of the well-known but almost universally disregarded tight combinatorial morphological-semantic structure of the verbal system of Biblical Hebrew, to show that this linguistic fossil testifies to the existence of a now extinct Proto-Language whose extremely tight verbal organization and meaningful architecture made it both structurally strikingly similar and expressively vastly superior to humanly designed Assembler languages, – an absolutely novel, paradoxical phenomenon, never before and nowhere else observed and apparently incompatible with the basic tenets of modern linguistic natural selection theories and, at the very least, crying out for new explanatory linguistic paradigms.

This study evaluated the impact of fuel subsidy removal on family income and sustainability in Ondo City. The study adopted a descriptive survey research design. Three (3) research questions guided the study. The study population was comprised of all household members in Ondo Metropolis. The total population of the study is two hundred and fifty-three thousand, four hundred and sixty-two (253,462). The sample size was one hundred and eighty-five (185) and was randomly selected using a simple random technique. A structured (...) questionnaire was the research instrument used to elicit responses from the respondents. Split-half reliability was used to determine the instrument's consistency, and a correlation coefficient of 0.76 was obtained. Data collected were analysed using descriptive statistics. The findings revealed that the fluctuation of oil prices in the international market necessitated subsidy removal, and the higher cost of transportation increases the cost of food items. The study concluded that the factors that necessitate fuel subsidy removal have a significant relationship with the possible challenges encountered by households in family sustenance. It was therefore recommended that the government's actions, such as increasing civil servants' wages and providing incentives for business owners, could enable them to cope with the increasing prices of commodities, offering a hopeful outlook for the future.

As the collective impact of human activity approaches Earth’s biophysical limits, the ethics of food become increasingly important. Hundreds of millions of people remain undernourished, yet only 60 percent of the global harvest is consumed by humans, while 35 percent is fed to livestock and 5 percent is used for biofuels and other industrial products. This essay considers the ethics of such use of edible nutrition for feedstock and biofuel. How humanity uses Earth’s land is a reflection of its values. (...) The current land-use arrangements, which divert 40 percent of all food to feed animals or create fuels, suggest that dietary and transportation preferences of wealthier individuals are considered more important than feeding undernourished people, or the stability of the wider biotic community.

Despite an enormous philosophical literature on models in science, surprisingly little has been written about data models and how they are constructed. In this paper, I examine the case of how paleodiversity data models are constructed from the fossil data. In particular, I show how paleontologists are using various model-based techniques to correct the data. Drawing on this research, I argue for the following related theses: first, the ‘purity’ of a data model is not a measure of its epistemic (...) reliability. Instead it is the fidelity of the data that matters. Second, the fidelity of a data model in capturing the signal of interest is a matter of degree. Third, the fidelity of a data model can be improved ‘vicariously’, such as through the use of post hoc model-based correction techniques. And, fourth, data models, like theoretical models, should be assessed as adequate for particular purposes. (shrink)

When a technology is seen as the right solution to a recognized problem, the development of alternative technologies comes under threat. To secure much-needed resources, proponents of alternative technologies must, in these conditions, restart societal discussion on the status quo, a process at once technological and discursive known as ‘path creation’. In this article, we investigate discussion-restarting strategies employed by supporters of emerging technologies in the field of solar fuels, particularly the advocates of a technology referred to as ‘artificial (...) photosynthesis’. For illustrative purposes we explore four such strategies: revisiting weak spots, resizing the problem, redefining the game, and renegotiating labels. We conclude with a methodological reflection on the empirical study of discursive strategies in a socio-technical system. We further suggest a more systematic application of discourse-analytical and argumentation-theoretical insights that can complement current scholarship on path dependence and path creation. (shrink)

The current informal practice of pharmacometrics as a combination art and science makes it hard to appreciate the role that informatics can and should play in the future of the discipline and to comprehend the gaps that exist because of its absence. The development of pharmacometric informatics has important implications for expediting decision making and for improving the reliability of decisions made in model-based development. We argue that well-defined informatics for pharmacometrics can lead to much needed improvements in the efficiency, (...) effectiveness, and reliability of the pharmacometrics process. The purpose of this paper is to provide a description of the pervasive yet often poorly appreciated role of informatics in improving the process of data assembly, a critical task in the delivery of pharmacometric analysis results. First, we provide a brief description of the pharmacometric analysis process. Second, we describe the business processes required to create analysis-ready data sets for the pharmacometrician. Third, we describe selected informatic elements required to support the pharmacometrics and data assembly processes. Finally, we offer specific suggestions for performing a systematic analysis of existing challenges as an approach to defi ning the next generation of pharmacometric informatics. (shrink)

The ninth and tenth chapters of the Origin mark a profound, if perhaps difficult to detect, shift in the book’s argumentative structure. In the previous few chapters and in the ninth, Darwin has been exploring a variety of objections to natural selection, some more obvious (where are all the fossils of transitional forms?) and some showing careful attention to challenging consequences of evolution (could selection really produce instincts?). Starting in the tenth, however, Darwin turns to showing us what kinds of (...) new and unexpected results evolutionary theory might be able to offer us, again in domains both predictable (extinction) and unexpected (biogeography, embryology). It is notable that it is the fossil record that serves as this pivot point, being both a source of potentially powerful objections to evolutionary theory and home to some of its most compelling new explanations. In this chapter, I present both sets of arguments and consider what role Darwin gave to fossil evidence, in the process attempting to discover why it might have played this unique role in two different parts of Darwin’s “long argument” for evolution by natural selection. Geology’s special place, I argue, derives at least in part from its particular importance in Darwin’s social and intellectual context. (shrink)

The article studies the energy efficiency of the economy and determines the need to reform the energy sector of Ukraine and conditions of its adaptation to EU requirements. Annual energy consumption in the world is about 14 billion tons of fuel. This is mainly organic origin resources – coal, oil, natural gas – 82 %, nuclear power – 7 %, hydroelectric energy – 3%, wood – 7 % renewable energy and – 1 %. The economic development of any country in (...) our time is determined not only by the number of extracted or consumed fuel and energy resources (FER), but the efficiency of their use – energy intensity of GDP, unit costs per unit of output. These figures are better in those countries which have established effective economic and legal mechanisms to encourage energy efficiency, which in turn stimulated the development of energy-saving technologies, equipment supply and services for energy efficiency. Analysis of international experience shows that Ukraine’s energy dependence can be reduced by: increasing production and consumption of domestic energy resources; increasing the efficiency of production, transportation and consumption of energy resources; diversification of energy imports and types of energy consumed. The study emphasizes that «energy is an important prerequisite for growth and development throughout the world, and despite the global financial crisis, demand for energy is growing steadily, particularly in the large economies of China, India and Brazil, developing countries. The authors provethat energy security is largely complicated by the fact that key energy resources are concentrated geopolitically. Most of the world’s oil and gas are found in several countries, some of which «are in a state of political turmoil and are not particularly friendly to US interests»(Gray F, 2010). The conclusions can be summarized that in the context of the main areas of research reducing risks to energy security of Ukraine are: energy efficiency economy (reduce unit cost of energy per unit of GDP); increase proved reserves and production of domestic energy resources; the transition from the use of expensive imported energy resources (oil, natural gas) to other fuels, especially domestic origin; opposition to fluctuations in energy prices (particularly by combating monopolization of the energy market, development of market infrastructure provisioning energy, preservation of state fuel and energy complex and the situation in the energy market); the development of the market principles of the electricity industry, promoting competition in this area.

Paleolinguistics (or linguistic paleontology) is a scientific discipline that combines the methodology of historical linguistics with archaeological insights. Specifically, paleolinguists aim to reconstruct the linguistic expression of a particular archeological culture. In this paper I deal with the methodology of paleolinguistics since this has recently come under the scrutiny of philosophersfor instance, Mallory (2020) has argued that tools of the philosophy of language can be employed for charting the space of legitimate use of paleolinguistics, most notably the position of semantic (...) internalism. Specifically, in his view, linguistic reconstructions of the Proto-Indo-European lexicon express Sinn or sense, whereas the proto-lexicon is best understood as a model of conceptual capabilities of a particular historical community. I want to show that one can consider semantic externalism as a more fruitful alternative. In other words, I propose to see the proto lexicon as a model that shows a feedback loop between speakers’ conceptual capabilities and scaffolding of these capabilities through speakers’ interaction with the environment. I show that the process of scaffolding can be mediated by cognitive fossils which, in turn, forges a tighter methodological link between paleolinguistics, archaeology, and the study of human cognition.

There is a common belief that genuine awareness and acceptance of the existence of anthropogenic climate change (as opposed to either ignorance or denial) automatically leads one to develop political and moral positions which advocate for collective human action toward minimizing suffering for all and adapting human societies toward a fossil-free future. This is a mistake. Against the idea that scientific awareness of the facts of climate change is enough to motivate a common ethical project of humanity toward a (...) unifying good, I argue that climate change awareness can just as well equally motivate heightened divisions of humanity into anti-egalitarian, xenophobic, class-differentiated zones of competitive survival. I call this climate barbarism, and seek to explain its conceptual grounds. (shrink)

This article identifies and compares meanings of wildfire risk mitigation for stakeholders in the Front Range of Colorado, USA. We examine the case of a collaborative partnership sponsored by government agencies and directed to decrease hazardous fuels in interface areas. Data were collected by way of key informant interviews and focus groups. The analysis is guided by the Circuit of Culture model in communication research. We found both shared and differing meanings between members of this partnership (the ‘‘producers’’) and (...) other stakeholders not formally in the partnership (the ‘‘consumers’’). We conclude that those promoting the partnership’s project to mitigate risk are primarily aligned with a discourse of scientific management. Stakeholders outside the partnership follow a discourse of community. We argue that failure to recognize and account for differences in the way risk mitigation is framed and related power dynamics could hamper the communicational efforts of the collaborative partnership and impact goals for fuels reduction. We recommend ways that both groups can capitalize on shared meanings and how agency managers and decision makers can build better working relationships with interface communities and other external stakeholders.

KK is the thesis that if you can know p, you can know that you can know p. Though it’s unpopular, a flurry of considerations has recently emerged in its favour. Here we add fuel to the fire: standard resources allow us to show that any failure of KK will lead to the knowability and assertability of abominable indicative conditionals of the form ‘If I don’t know it, p’. Such conditionals are manifestly not assertable—a fact that KK defenders can easily (...) explain. I survey a variety of KK-denying responses and find them wanting. Those who object to the knowability of such conditionals must either deny the possibility of harmony between knowledge and belief, or deny well-supported connections between conditional and unconditional attitudes. Meanwhile, those who grant knowability owe us an explanation of such conditionals’ unassertability—yet no successful explanations are on offer. Upshot: we have new evidence for KK. (shrink)

An exciting theory in neuroscience is that the brain is an organ for prediction error minimization. This theory is rapidly gaining influence and is set to dominate the science of mind and brain in the years to come. PEM has extreme explanatory ambition, and profound philosophical implications. Here, I assume the theory, briefly explain it, and then I argue that PEM implies that the brain is essentially self-evidencing. This means it is imperative to identify an evidentiary boundary between the brain (...) and its environment. This boundary defines the mind-world relation, opens the door to skepticism, and makes the mind transpire as more inferentially secluded and neurocentrically skull-bound than many would nowadays think. Therefore, PEM somewhat deflates contemporary hypotheses that cognition is extended, embodied and enactive; however, it can nevertheless accommodate the kinds of cases that fuel these hypotheses.

Around 540 million years ago there was a sudden, dramatic adaptive radiation known as the Cambrian Explosion. This event marked the origin of almost all of the phyla (major lineages characterized by fundamental body plans) of animals that would ever live on earth, as well the appearance of many notable features such as rigid skeletons and other hard parts, complex jointed appendages, eyes, and brains. This radical evolutionary event has been a major puzzle for evolutionary biologists since Darwin, and while (...) our understanding of it has recently improved with new fossil finds, richer molecular phylogenies, and better grasp of ecological, evolutionary, and developmental processes generally, unanswered questions remain. In this paper I argue that a basic cognitive toolkit for embodied, object-oriented, spatial cognition (what I call Basic Cognitive Embodiment) is a practical necessity for control of a large, mobile, complexly articulated body in space. This hypothesis allows us to relate the complexification of animal bodies to the complexification of perception, cognition and behavior in a way that can help to fill in gaps in our emerging picture of the Cambrian Explosion, as well as shed light on the deep evolutionary origins of the mind.

Jennifer Lackey ('Testimonial Knowledge and Transmission' The Philosophical Quarterly 1999) and Peter Graham ('Conveying Information, Synthese 2000, 'Transferring Knowledge' Nous 2000) offered counterexamples to show that a hearer can acquire knowledge that P from a speaker who asserts that P, but the speaker does not know that P. These examples suggest testimony can generate knowledge. The showpiece of Lackey's examples is the Schoolteacher case. This paper shows that Lackey's case does not undermine the orthodox view that testimony cannot generate knowledge. (...) This paper explains why Lackey's arguments to the contrary are ineffective for they misunderstand the intuitive rationale for the view that testimony cannot generate knowledge. This paper then elaborates on a version of the case from Graham's paper 'Conveying Information' (the Fossil case) that effectively shows that testimony can generate knowledge. This paper then provides a deeper informative explanation for how it is that testimony transfers knowledge, and why there should be cases where testimony generates knowledge. (shrink)

The nationwide economic reform in 1986 transformed Vietnam from a centrally planned economy to a socialist-oriented market economy. Entrepreneurs and entrepreneurial spirits within the populace are suggested to fuel the structural changes. Despite the importance of entrepreneurship in Vietnam’s economy, studies in Vietnam mainly pay attention to the practical aspects of entrepreneurial activities and neglect the cognitive and theoretical aspects of entrepreneurship. Thus, the current study employs the information-processing perspective of the Mindsponge Theory to explore how entrepreneurs’ knowledge accumulation can (...) affect their perceived likelihood of business success. Bayesian analysis indicates that business-related experience positively affects entrepreneurs’ business success likelihood. Greater willingness/readiness to transform thinking, acting, and beliefs can improve the business success of entrepreneurs who study others’ failures carefully. However, for entrepreneurs who perceive learning from others’ failures as unnecessary, higher willingness/readiness to transform diminishes their chance of success. Based on these findings, we recommend Vietnamese entrepreneurs accumulate knowledge through experience, learning, and an open mind for better decision-making and innovation creation capabilities. However, the learning process should be selective. (shrink)

Epistemic peer disagreement raises interesting questions, both in epistemology and in philosophy of science. When is it reasonable to defer to the opinion of others, and when should we hold fast to our original beliefs? What can we learn from the fact that an epistemic peer disagrees with us? A question that has received relatively little attention in these debates is the value of epistemic peer disagreement—can it help us to further epistemic goals, and, if so, how? We investigate this (...) through a recent case in paleoanthropology: the debate on the taxonomic status of Homo floresiensis remains unresolved, with some authors arguing the fossils represent a novel hominin species, and others claiming that they are Homo sapiens with congenital growth disorders. Our examination of this case in the recent history of science provides insights into the value of peer disagreement, indicating that it is especially valuable if one does not straightaway defer to a peer’s conclusions, but nevertheless remains open to a peer’s evidence and arguments.

Drawing from enactivist theory, this paper examines how certain cases of transgenerational trauma manifest as Post-Traumatic Stress Disorder in the descendants of survivors who did not experience the event directly. It argues that psychopathology develops from an embodied form of vicarious memory, conveyed through mimetic capacities and emotional resonances that involve the transfer of emotional and behavioral patterns from parents to children, affecting their sense of self. Children’s reenactments of their parents' emotional states do not merely replay the parents' trauma (...) but are also perceived and integrated into the children’s life as their own. This, in turn, biases their sense-making, which is further reinforced by background emotions in the household. Over time, certain mnemonic features contribute to the persistence of the initial emotional load, such as the simplification of events in collective memory and the reliance of embodied vicarious memories on somatic markers, which also fuel PTSD development. Finally, the paper briefly explores the implications of embodiment for understanding mnemonic causality. (shrink)

The integration of postmodern thinking in the sciences, especially in biology, has been subject to harsh criticism. Contrary to Enlightenment ideals of objectivity and neutrality in the scientific method, the postmodern stance holds that truth is relative, not universal, and therefore progress is ambiguous. The effect of postmodern thought has ramifications that extend from the distrust of preexisting scientific conclusions to questions about the impact of progress in society. It also reflects skepticism about the scientific endeavor. Especially when postmodern ideas (...) are considered to have gained traction, the anti-postmodern critique has become harsher. At stake is whether postmodern notions are indeed irrelevant, and—even more important—whether they compromise scientific progress. The conditional significance of universals in biology and the role of historicity in the evolutionary process makes biology different from the other natural sciences and subjects it to the postmodern critique. This article argues that rather than being viewed as a science that seeks universals, biology should be viewed as a construct, more relevant to a technology, aiming to attain functionalities. Such recognition may fuel progress and assist biology in attaining its ultimate goal, which is to address the most intricate questions about the living world. (shrink)

Contemporary philosophical attitudes toward beauty are hard to reconcile with its importance in the history of philosophy. Philosophers used to allow it a starring role in their theories of autonomy, morality, or the good life. But today, if beauty is discussed at all, it is often explicitly denied any such importance. This is due, in part, to the thought that beauty is the object of “disinterested pleasure”. In this paper I clarify the notion of disinterest and develop two general strategies (...) for resisting the emphasis on it, in the hopes of getting a clearer view of beauty’s significance. I present and discuss several literary depictions of the encounter with beauty that motivate both strategies. These depictions illustrate the ways in which aesthetic experience can be personally transformative. I argue that they present difficulties for disinterest theories and suggest we abandon the concept of disinterest to focus instead on the special kind of interest beauty fuels. I propose a closer look at the Platonic thought that beauty is the object of love. (shrink)

In earlier work, I predicted that we would probably not be able to determine the colors of the dinosaurs. I lost this epistemic bet against science in dramatic fashion when scientists discovered that it is possible to draw inferences about dinosaur coloration based on the microstructure of fossil feathers (Vinther et al., 2008). This paper is an exercise in philosophical error analysis. I examine this episode with two questions in mind. First, does this case lend any support to epistemic (...) optimism about historical science? Second, under what conditions is it rational to make predictions about what questions scientists will or will not be able answer? In reply to the first question, I argue that the recent work on the colors of the dinosaurs matters less to the debate about the epistemology of historical science than it might seem. In reply to the second question, I argue that it is difficult to specify a policy that would rule out the failed bet without also being too conservative. (shrink)

Despite the widespread use of the notion of moral intuition, its psychological features remain a matter of debate and it is unclear why the capacity to experience moral intuitions evolved in humans. We first survey standard accounts of moral intuition, pointing out their interesting and problematic aspects. Drawing lessons from this analysis, we propose a novel account of moral intuitions which captures their phenomenological, mechanistic, and evolutionary features. Moral intuitions are composed of two elements: an evaluative mental state and a (...) feeling of rightness (FOR). We illustrate the phenomenology of the FOR with examples of non-moral and moral cases, and provide a biological and mechanistic account: the emergence of human reasoning capacities created a need for the co-evolution of a psychological system producing the feeling of rightness (the FORs). This system is triggered when we experience conflicting evaluations. The FORs renders evaluations resulting from rational deliberation less compelling than the evaluations produced by simple evolved systems. It thus facilitates optimal decision-making, preventing excessive interference by rational deliberation. Our account sheds light on why moral intuitions are so frequently experienced and why they are so compelling and resistant to argument. In addition, the account fuels interesting speculations about common metaethical intuitions. (shrink)

Creationists who object to evolution in the science curriculum of public schools often cite Jonathan Well’s book Icons of Evolution in their support (Wells 2000). In the third chapter of his book Wells claims that neither paleontological nor molecular evidence supports the thesis that the history of life is an evolutionary process of descent from preexisting ancestors. We argue that Wells inappropriately relies upon ambiguities inherent in the term ‘Darwinian’ and the phrase ‘Darwin’s theory’. Furthermore, he does not accurately distinguish (...) between the overwhelming evidence that supports the thesis of common descent and controversies that pertain to causal mechanisms such as natural selection. We also argue that Wells’ attempts to undermine the evidence in support of common descent are flawed and his characterization of the relevant data is misleading. In particular, his assessment of the ‘Cambrian explosion’ does not do justice to the fossil record. Nor do his selective references to debate about molecular and paleontological phylogenies constitute a case against common descent. We conclude that the fossil and molecular evidence is more than sufficient to warrant science educators to present common descent as a well-established scientific fact. We also argue that diagrams depicting the ‘tree of life’ can be pedagogically useful as simplified representations of the history of life. (shrink)

Both the slasher movie and its more recent counterpart the "torture porn" film centralize graphic depictions of violence. This article inspects the nature of these portrayals by examining a motif commonly found in the cinema of homicide, dubbed here the "pure moment of murder": that is, the moment in which two characters’ bodies adjoin onscreen in an instance of graphic violence. By exploring a number of these incidents (and their various modes of representation) in American horror films ranging from Psycho (...) (1960) to Saw VI (2009), the article aims to expound how these images of slaughter demonstrate (albeit in an augmented, hyperbolic manner) a number of long-standing problems surrounding selfhood that continue to fuel philosophical discussion. The article argues that the visual adjoining of victim and killer onscreen echoes the conundrum that in order to attain identity, the individual requires and yet simultaneously repudiates the Other that constitutes unique subjectivity.
