    Having an Anthropocene Body: Hydrocarbons, Biofuels and Metabolism.Adrian Mackenzie - 2014 - Body and Society 20 (1):3-30.
    What does it mean to have an Anthropocene body? The Anthropocene period is putatively defined by flows of hydrocarbons and hydrocarbon derivatives (fuels, plastics, fertilizers, etc.), and the very term ‘Anthropocene’ suggests an increasing awareness of the finitude and contingency of contemporary corporealities. This article explores the idea of modelling an Anthropocene body as a living/non-living metabolic process. While identifying bodies with molecules raises a host of problems, metabolism and hydrocarbon biomolecules display a gamut of forms of possession (...)

    Wax, sex and the origin of species: Dual roles of insect cuticular hydrocarbons in adaptation and mating.Henry Chung & Sean B. Carroll - 2015 - Bioessays 37 (7):822-830.
    Evolutionary changes in traits that affect both ecological divergence and mating signals could lead to reproductive isolation and the formation of new species. Insect cuticular hydrocarbons (CHCs) are potential examples of such dual traits. They form a waxy layer on the cuticle of the insect to maintain water balance and prevent desiccation, while also acting as signaling molecules in mate recognition and chemical communication. Because the synthesis of these hydrocarbons in insect oenocytes occurs through a common biochemical pathway, natural or (...)

    Manifestations of corporate social responsibility as sensemaking and sensegiving in a hydrocarbon industry.Nathan Andrews - 2021 - Business and Society Review 126 (2):211-234.
    There is a large body of literature that examines different dimensions of corporate social responsibility (CSR) in Africa, with many focusing on the false promises of these corporate initiatives. Contrary to simplistic claims of CSR being merely window-dressing, however, this paper reveals that although several rhetorical proclamations underpin the idea, such statements are often given instrumental meaning through diverse mechanisms (e.g., interpretation of cues toward the proactive (re)construction of identity, (inter)subjective discourses on social legitimacy, and acts of “issue selling”) that (...)

    The pheromonal role of cuticular hydrocarbons in Drosophila melanogaster.Jean-François Ferveur - 1997 - Bioessays 19 (4):353-358.
    Pheromones play a curcial role in mate stimulation and discrimination. In the fruit fly Drosophila, the most abundant cuticular hydrocarbons act as sex pheromones during courtship behavior. There are several active molecules and they compose a sex‐ and species‐specific pheromonal bouquet. Different species from the Drosophila melanogaster subgroup have adopted alternative systems of chemical mate recognition. Recent exploration of these interspecific variations, and of intraspecific variations, has led to the characterization of genes and to the mapping of structures that process (...)

    Crisis in the Tar Sands: Fossil Capitalism and the Future of the Alberta Hydrocarbon Economy.Tyler McCreary - 2021 - Historical Materialism 30 (1):31-65.
    Using a case study of Alberta, Canada, this paper demonstrates how a geographic critique of fossil capitalism helps elucidate the tensions shaping tar sands development. Conflicts over pipelines and Indigenous territorial claims are challenging development trajectories, as tar sands companies need to expand access to markets in order to expand production. While these conflicts are now well recognised, there are also broader dynamics shaping development. States face a rentier’s dilemma, relying on capital investments to realise resource value. Political responses to (...)

    The molecular biology of the polycyclic aromatic hydrocarbon inducible cytochrome P‐450; the past is prologue.P. L. Iversen, R. N. Hines & Edward Bresnick - 1986 - Bioessays 4 (1):15-19.
    The heme‐containing cytochromes P‐450 are a ubiquitous family of monooxygenase isozymes responsible for the oxidative metabolism of a wide variety of endogenous as well as exogenous compounds. Many of the compounds metabolized by this enzyme system are effectively detoxified and converted to derivatives more easily eliminated from the organism. However, some compounds can be activated to reactive species capable of eliciting a cascade of toxic lesions, including cancer. Since its discovery nearly 30 years ago, the cytochrome P‐450 enzyme system has (...)

    The origin and evolution of social insect queen pheromones: Novel hypotheses and outstanding problems.Cintia A. Oi, Jelle S. van Zweden, Ricardo C. Oliveira, Annette Van Oystaeyen, Fabio S. Nascimento & Tom Wenseleers - 2015 - Bioessays 37 (7):808-821.
    Queen pheromones, which signal the presence of a fertile queen and induce daughter workers to remain sterile, are considered to play a key role in regulating the reproductive division of labor of insect societies. Although queen pheromones were long thought to be highly taxon‐specific, recent studies have shown that structurally related long‐chain hydrocarbons act as conserved queen signals across several independently evolved lineages of social insects. These results imply that social insect queen pheromones are very ancient and likely derived from (...)

  13. A neglected aspect of the puzzle of chemical structure: how history helps.Joseph E. Earley - 2012 - Foundations of Chemistry 14 (3):235-243.
    Intra-molecular connectivity (that is, chemical structure) does not emerge from computations based on fundamental quantum-mechanical principles. In order to compute molecular electronic energies (of C 3 H 4 hydrocarbons, for instance) quantum chemists must insert intra-molecular connectivity “by hand.” Some take this as an indication that chemistry cannot be reduced to physics: others consider it as evidence that quantum chemistry needs new logical foundations. Such discussions are generally synchronic rather than diachronic —that is, they neglect ‘historical’ aspects. However, systems of (...)

    Ethylene hormone receptor action in Arabidopsis.Caren Chang & Ruth Stadler - 2001 - Bioessays 23 (7):619-627.
    Small gaseous molecules play important roles in biological signaling in both animal and plant physiology. The hydrocarbon gas ethylene has long been known to regulate diverse aspects of plant growth and development, including fruit ripening, leaf senescence and flower abscission. Recent progress has been made toward identifying components involved in ethylene signal transduction in the plant Arabidopsis thaliana. Ethylene is perceived by five receptors that have similarity to two‐component signaling proteins. The hydrophobic amino‐terminus of the receptors binds ethylene, and (...)

    Pesticides and the perils of synecdoche in the history of science and environmental history.Frederick Rowe Davis - 2019 - History of Science 57 (4):469-492.
    When the Environmental Protection Agency banned DDT late in 1972, environmentalists hailed the decision. Indeed, the DDT ban became a symbol of the power of environmental activism in America. Since the ban, several species that were decimated by the effects of DDT have significantly recovered, including bald eagles, peregrines, ospreys, and brown pelicans. Yet a careful reading of Rachel Carson’s Silent Spring reveals DDT to be but one of hundreds of chemicals in thousands of formulations. Carson called for a reduction (...)

    Model of State Management of Petroleum Sector – Case of Norway.Katarzyna Dośpiał-Borysiak - 2017 - International Studies. Interdisciplinary Political and Cultural Journal 20 (1):97-112.
    The aim of the article is to discuss the Norwegian Model of hydrocarbon management and its impact on building a just and equal society. Since 1972, the model has been based on the separation of policy, commercial, and regulatory functions. Within each area there is state-controlled institution with its own distinct role. This model of separation of duties is however combined with other unique features which cannot be easily copied by other counties. These include a long tradition and high (...)

    Velikovsky in collision.Stephen Jay Gould - manuscript
    ot long ago, Venus emerged from Jupiter, like Athena from the brow of Zeus—literally! It then assumed the form and orbit of a comet. In 1500 B.C., at the time of the Jewish exodus from Egypt, the earth passed twice through Venus's tail, bringing both blessing and chaos; manna from heaven (or rather from hydrocarbons of a cometary tail) and the bloody rivers of the Mosaic plagues (iron from the same tail). Continuing its erratic course, Venus collided with (or nearly (...)

    Activity of closed d-shells in noble metal atoms.Octavio Novaro - 2004 - Foundations of Chemistry 7 (3):241-268.
    The Periodic Table has the column of the noble gas atoms (He, Ne, Ar, Kr, Xe, Rn) as one of its main pillars. Indeed the inert chemical nature of their closed shell structure is so striking that it is sometimes extended to all such structures. Is it true however that any closed shell, say a closed d-subshell will denote a lack of chemical activity? Take the noble metals for instance, so renowned for their catalytic capacity. Platinum has 10 electrons in (...)

    Plato's Revenge: Politics in the Age of Ecology.Patrick Ophuls - 2013 - MIT Press.
    In this provocative call for a new ecological politics, William Ophuls starts from a radical premise: "sustainability" is impossible. We are on an industrial _Titanic_, fueled by rapidly depleting stocks of fossil hydrocarbons. Making the deck chairs from recyclable materials and feeding the boilers with biofuels is futile. In the end, the ship is doomed by the laws of thermodynamics and by the implacable biological and geological limits that are already beginning to pinch. Ophuls warns us that we are headed (...)

    An Evaluation of the AirCare Program Based on Cost-Benefit and Cost-Effectiveness Analyses.Dianle Wang & Hsiaotao T. Bi - 2006 - Bulletin of Science, Technology and Society 26 (6):472-478.
    A cost-benefit analysis of the AirCare program in the province of British Columbia on the basis of emissions cost factors from the literature showed a benefit outweighing the cost. Furthermore, a cost-effectiveness analysis comparing the AirCare program with a hybrid-car rebate program revealed that the AirCare program is more effective in reducing emissions of major air pollutants such as NOx, hydrocarbons, and CO. However, the hybrid-car rebate program contributes significantly to the reduction of greenhouse gas emissions because of much greater (...)

    Rebellion to Reform in Bolivia. Part III: Neoliberal Continuities, the Autonomist Right, and the Political Economy of Indigenous Struggle.Jeffery Webber - 2008 - Historical Materialism 16 (4):67-109.
    This article presents a broad analysis of the political economy and dynamics of social change during the first year of the Evo Morales government in Bolivia. It situates this analysis in the wider historical context of left-indigenous insurrection between 2000 and 2005, the changing character of contemporary capitalism imperialism, and the resurgence of anti-neoliberalism and anti-imperialism elsewhere in Latin America. It considers at a general level the overarching dilemmas of revolution and reform. Part III examines the complexities of the politics (...)

    The role of mathematics in the experimental/theoretical/computational trichotomy of chemistry.R. Bruce King - 2000 - Foundations of Chemistry 2 (3):221-236.
    The drastically increasing availability ofmodern computers coupled with the equally drasticallylower cost of a given amount of computer power inrecent years has resulted in the evolution of thetraditional experimental/theoretical dichotomy inchemistry into anexperimental/theoretical/computational trichotomy. This trichotomy can be schematically represented by atriangle with experimental,theoretical, and computational chemistry at the threevertices. The ET and EC edges of the ETC triangledepict the uses of theoretical and computationalchemistry, respectively, to predict and interpretexperimental results. The TC edge depicts therelationship between theoretical and computationalchemistry. Mathematics (...)

    Counter-Commoditization: Decision Making, Language, Localization.Thomas Princen - 2012 - Bulletin of Science, Technology and Society 32 (1):7-17.
    Commoditization seems immutable and unstoppable but, like other social processes, its prevalence is context dependent. The enabling context for commoditization has been cheap fossil fuels, economic growth, and ever-increasing energy and material throughput. In fact, the scientific findings of ecological, climate, footprint, and material flow studies all point in the same direction—excess throughput. We cannot grow our way out of growth-driven crisis; new technologies will not create new sources of energy or new waste sinks. Counter-commoditization measures can take the form (...)

    Redundancy as a Driving Force of Human Existence.Valery Goryunov - 2015 - Dialogue and Universalism 25 (2):244-255.
    The technosocial formula is a key concept in social cognition. It means that society needs a larger amount of life resources than people can produce. The main social goal means relationship along with technology is a provision of material production. Man is redundant to the extent to which his appearance goes beyond the natural balance. Production growth increases the amount of excess consumption and population, and at the same time the scarcity of natural resources. The volume of world energy consumption (...)

    Cartographie de la controverse d’exploration et d’exploitation du gaz de schiste en Algérie.Neila Zerguini - 2016 - Éthique Publique 18 (1).
    En Algérie, la nouvelle loi sur les hydrocarbures autorise l’exploitation des hydrocarbures non conventionnels, incluant le gaz de schiste, dont les réserves ont récemment été réévaluées à la hausse. Ces rebondissements ont suscité autant l’intérêt que l’inquiétude de l’opinion publique. Très sommairement, le débat est perçu comme opposant les « pour » l’exploitation qui mettent en avant des gains économiques aux « contre », écologistes s’opposant à la fracturation hydraulique. Cette dualité ne rend pas justice à la complexité de la (...)
