  1. The Conditions for Ethical Chemical Restraints.Parker Crutchfield & Michael Redinger - 2024 - American Journal of Bioethics Neuroscience 15 (1):3-16.
    The practice of medicine frequently involves the unconsented restriction of liberty. The reasons for unilateral liberty restrictions are typically that being confined, strapped down, or sedated are necessary to prevent the person from harming themselves or others. In this paper, we target the ethics of chemical restraints, which are medications that are used to intentionally restrict the mental states associated with the unwanted behaviors, and are typically not specifically indicated for the condition for which the patient is being (...)

  4. The Chemical Bond is a Real Pattern.Vanessa A. Seifert - forthcoming - Philosophy of Science:1-47.
    There is a persisting debate about what chemical bonds are and whether they exist. I argue that chemical bonds are real patterns of interactions between subatomic particles. This proposal resolves the problems raised in the context of existing understandings of the chemical bond and provides a novel way to defend the reality of chemical bonds.

  5. Messy Chemical Kinds.Joyce C. Havstad - 2018 - British Journal for the Philosophy of Science 69 (3):719-743.
    Following Kripke and Putnam, the received view of chemical kinds has been a microstructuralist one. To be a microstructuralist about chemical kinds is to think that membership in said kinds is conferred by microstructural properties. Recently, the received microstructuralist view has been elaborated and defended, but it has also been attacked on the basis of complexities, both chemical and ontological. Here, I look at which complexities really challenge the microstructuralist view; at how the view itself might be (...)

  6. Consensus, Convergence, Restraint, and Religion.Paul Billingham - 2018 - Journal of Moral Philosophy 15 (3):345-361.
    This essay critically assesses the central claim of Kevin Vallier’s Liberal Politics and Public Faith: that public religious faith and public reason liberalism can be reconciled, because the values underlying public reason liberalism should lead us to endorse the ‘convergence view’, rather than the mainstream consensus view. The convergence view is friendlier to religious faith, because it jettisons the consensus view’s much-criticised ‘duty of restraint’. I present several challenges to Vallier’s claim. Firstly, if Vallier is right to reject the duty (...)

    Long-standing neglect of the chemical senses in the philosophy of perception is due, mostly, to their being regarded as ‘lower’ senses. Smell, taste, and chemically irritated touch are thought to produce mere bodily sensations. However, empirically informed theories of perception can show how these senses lead to perception of objective properties, and why they cannot be treated as special cases of perception modelled on vision. The senses of taste, touch, and smell also combine to create unified perceptions of flavour. (...)

  8. Chemical Action: What is it and Why Does it Really Matter?W. John Koolage & W. John Koolage & Ralph Hall - 2011 - Journal of Nanoparticle Research 13 (13):1401-1427.
    Nanotechnology, as with many technologies before it, places a strain on existing legislation and poses a challenge to all administrative agencies tasked with regulating technology-based products. It is easy to see how statutory schemes become outdated, as our ability to understand and affect the world progresses. In this article, we address the regulatory problems that nanotechnology posses for the Food and Drug Administration’s (FDA) classification structure for ‘‘drugs’’ and ‘‘devices.’’ The last major modification to these terms was in 1976, with (...)

  9. Chemical arbitrariness and the causal role of molecular adapters.Oliver M. Lean - 2019 - Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences 78:101180.
    Jacques Monod (1971) argued that certain molecular processes rely critically on the property of chemical arbitrariness, which he claimed allows those processes to “transcend the laws of chemistry”. It seems natural, as some philosophers have done, to interpret this in modal terms: a biological relationship is chemically arbitrary if it is possible, within the constraints of chemical “law”, for that relationship to have been otherwise than it is. But while modality is certainly important for understanding chemical arbitrariness, (...)

    The chemical characterization of the substance responsible for the phenomenon of “transformation” of pneumococci was presented in the now famous 1944 paper by Avery, MacLeod, and McCarty. Reception of this work was mixed. Although interpreting their results as evidence that deoxyribonucleic acid (DNA) is the molecule responsible for genetic changes was, at the time, controversial, this paper has been retrospectively celebrated as providing such evidence. The mixed and changing assessment of the evidence presented in the paper was due to (...)

    This book examines the way in which Robert Boyle seeks to accommodate his complex chemical philosophy within the framework of a mechanistic theory of matter. More specifically, the book proposes that Boyle regards chemical qualities as properties that emerged from the mechanistic structure of chymical atoms. Within Boyle’s chemical ontology, chymical atoms are structured concretions of particles that Boyle regards as chemically elementary entities, that is, as chemical wholes that resist experimental analysis. Although this interpretation of (...)

  13. The Principle of Restraint: Public Reason and the Reform of Public Administration.Gabriele Badano - 2020 - Political Studies 68 (1):110-127.
    Normative political theorists have been growing more and more aware of the many difficult questions raised by the discretionary power inevitably left to public administrators. This article aims to advance a novel normative principle, called ‘principle of restraint’, regulating reform of established administrative agencies. I argue that the ability of public administrators to exercise their power in accordance with the requirements of public reason is protected by an attitude of restraint on the part of potential reformers. Specifically, they should refrain (...)

  14. Chemical Castration as Punishment.Katrina L. Sifferd - 2020 - In Nicole A. Vincent, Thomas Nadelhoffer & Allan McCay (eds.), Neurointerventions and the Law: Regulating Human Mental Capacity. Oxford University Press, Usa.
    This chapter explores whether chemical castration can be justified as a form of criminal punishment. The author argues that castration via the drug medroxyprogesterone acetate (MPA), or some similar drug, does not achieve the punishment aims of retribution, deterrence, or incapacitation, but might serve as punishment in the form of rehabilitative treatment. However, current U.S. chemical castration statutes are too broad to be justified as rehabilitative. The state is warranted in targeting psychological states in criminal defendants for rehabilitative (...)

    The entry of resonance into chemistry, or the reception of the theory of resonance in the chemical community, has drawn considerable attention from historians of science. In particular, they have noted Pauling's ¯amboyant yet effective style of exposition, which became a factor in the early popularity of the resonance theory in comparison to the molecular orbital theory, another way of applying quantum mechanics to chemical problems.$ To be sure, the non-mathematical presentation of the resonance theory by Pauling and (...)

  16. Chemical possibility and modal semantics.Mark Sharlow - 2007
    This paper is a study of a distinctively chemical notion of possibility. This is the notion of possibility that occurs in chemical discourses when chemists speak of the possibility or impossibility of achieving a given result through chemical means. This notion pertains to the possibility of processes, not of compounds, so it differs from the kind of chemical possibility mentioned in Wittgenstein's Philosophical Investigations or the kinds discussed in the literature on Putnam's Twin Earth argument. I (...)

    Today, many armed forces consider teaching virtues to be an important complement to imposing rules and codes from above. Yet, it is mainly established military virtues such as courage and loyalty that dominate both the lists of virtues and values of most militaries and the growing body of literature on military virtues. Some of these virtues, however, may be less suited for today’s missions, which more often than not require restraint on the part of military personnel. This chapter looks into (...)

  19. Retributive Justice in the Breivik Case: Exploring the Rationale for Punitive Restraint in Response to the Worst Crimes.David Chelsom Vogt - 2024 - Retfaerd - Nordic Journal of Law and Justice 1:25-43.
    The article discusses retributive justice and punitive restraint in response to the worst types of crime. I take the Breivik Case as a starting point. Anders Behring Breivik was sentenced to 21 years of preventive detention for killing 69 people, mainly youths, at Utøya and 8 people in Oslo on July 22nd, 2011. Retributivist theories as well as commonly held retributive intuitions suggest that much harsher punishment is required for such crimes. According to some retributivist theories, most notably on the (...)

    We are immersed within an odorous sea of chemical currents that we parse into individual odors with complex structures. Odors have been posited as determined by the structural relation between the molecules that compose the chemical compounds and their interactions with the receptor site. But, naturally occurring smells are parsed from gaseous odor plumes. To give a comprehensive account of the nature of odors the chemosciences must account for these large distributed entities as well. We offer a focused (...)

    This essay undertakes a critical examination of Kevin Vallier’s Principle of Convergent Restraint (PCR) within the framework of public reason liberalism. The article begins by scrutinizing the PCR’s inaugural provision: intelligibility, advancing the argument that Vallier’s explication of intelligibility contradicts the requisites of public justification in liberal democracies. It argues that Vallier’s predilection for intelligibility over accessibility runs afoul of the fundamental principles underpinning public reason and pluralistic liberalism. It then provides an evaluation of the second provision, narrow restraint, asserting (...)

A central idea in modern biology is that in addition to the four entities making reality, matter, energy, space and time, a fifth one, information, plays a central role. As a consequence of this central importance of the management of information, the bacterial cell is organised as a Turing machine, where the machine, with its compartments defining an inside and an outside and its metabolism, reads and (...)

    Abstract: Global chemical contamination is an underexplored source of global catastrophic risks that is estimated to have low a priori probability. However, events such as pollinating insects’ population decline and lowering of the human male sperm count hint at some toxic exposure accumulation and thus could be a global catastrophic risk event if not prevented by future medical advances. We identified several potentially dangerous sources of the global chemical contamination, which may happen now or could happen in the (...)

    Philosophers have long debated ‘substrate’ and ‘bundle’ theories as to how properties hold together in objects ― but have neglected to consider that every chemical entity is defined by closure of relationships among components ― here designated ‘Closure Louis de Broglie.’ That type of closure underlies the coherence of spectroscopic and chemical properties of chemical substances, and is importantly implicated in the stability and definition of entities of many other types, including those usually involved in philosophic discourse (...)

    Despite the lack of evidence for their effectiveness, the use of physical restraints for patients is widespread. The best ethical justification for restraining patients is that it prevents them from harming themselves. We argue that even if the empirical evidence supported their effectiveness in achieving this aim, their use would nevertheless be unethical, so long as well known exceptions to informed consent fail to apply. Specifically, we argue that ethically justifiable restraint use demands certain necessary and sufficient conditions. These (...)

    In learning chemistry at the entry level, many learners labor under misconceptions about the subject matter that are so fundamental that they are typically never addressed. A fundamental misconception in chemistry appears to arise from an adding of existing phenomenal concepts to newly-acquired chemical concepts, so that beginning learners think of chemical entities as themselves having the very same ‘macro’ properties that we observe through the senses. Those who teach or practice chemistry never acquire these misconceptions because they (...)

    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 (...)

Among others, the identification of the correct symmetry group and its decomposition into subgroups has remained a problem to this day. In an effort to deepen our limited understanding of (...)

  40. Necessary Laws and Chemical Kinds.Nora Berenstain - 2014 - Australasian Journal of Philosophy 92 (4):631-647.
    Contingentism, generally contrasted with law necessitarianism, is the view that the laws of nature are contingent. It is often coupled with the claim that their contingency is knowable a priori. This paper considers Bird's (2001, 2002, 2005, 2007) arguments for the thesis that, necessarily, salt dissolves in water; and it defends his view against Beebee's (2001) and Psillos's (2002) contingentist objections. A new contingentist objection is offered and several reasons for scepticism about its success are raised. It is concluded that (...)

Bologna: CLUEB.
    It is suggested that the view which considers the approach of chemistry reducible to that of physics is not correct. Chemistry explains the properties of materials in terms of special entities, the molecules; hence, in its descent toward the extremely small, it stops at a certain level of complexity, and adopts an “ontological” point of view; which implies the introduction of unique structural concepts, such as the chemical bond. Historical considerations confirm the view that chemistry is complementary to physics. (...)

    The emergence in Britain of chemical engineering, by mid‐century the fourth largest engineering specialism, was a hesitant and drawn out process. This article analyses the organisational politics behind the recognition of the technical occupation and profession from the First World War through to the end of the 1920s. The collective sense of professional identity among nascent ‘chemical engineers’ developed rapidly during this time owing to associations which promoted their cause among potential patrons. -/- .

  45. Experiment and Quantification of Weight: Late-Renaissance and Early Modern Medical, Mineralogical and Chemical Discussions on the Weights of Metals.Silvia Manzo - 2020 - Early Science and Medicine 25 (4):388-412.
    This paper explores how a set of observations on the weight of lead were interpreted and assessed between the 1540s and the 1630s across three different interconnecting disciplines: medicine, mineralogy and chemistry. The epistemic import of these discussions will be demonstrated by showing: 1) the changing role and articulation of experience and quantification in the investigation of metals; and 2) the notions associated with weight in different disciplinary frameworks. In medicine and mineralogy, weight was not considered as a specific subject (...)

  46. GREEN PRACTICES AND CORPORATE SUSTAINABILITY PERFORMANCE OF CHEMICAL MANUFACTURING ORGANISATIONS IN MALAYSIA: THE MODERATING ROLE OF ISLAMIC WORK ETHICS, ORGANISATION SIZE, AND ORGANISATION AGE.Maryam Jamilah Asha’Ari - 2020 - Dissertation, Universiti Tenaga Nasional
    Sustainability is a crucial issue for many sectors in Malaysia, including the manufacturing sector. Many businesses, especially the chemical manufacturing industry, aim to achieve a sustainable business through the implementation of green practices. Green practices provide guidelines for the employees to simultaneously sustain the organisation in a sustainable manner and carry out the required manufacturing activities. Focusing on that, this study aimed to examine the effects of green practices on corporate sustainability performance through Islamic work ethics, organisation size, and (...)

  47. Identity through alliances: the British chemical engineer.Sean F. Johnston & Colin Divall - 1999 - In I. Hellberg, M. Saks & C. Benoit (eds.), Professional Identities in Transition: Cross-Cultural Dimensions. Almqvist & Wiksell International. pp. 391-408.
    The development of a professional identity is particularly interesting for those occupations that have a troubled emergence. The hinterland between science and technology accommodates many such ‘in-between’ subjects, which appear to have distinct attributes. Some of these specialisms disappear in the face of culturally stronger occupations. Others endure, their technical expertise becoming appropriated or mutated to serve the needs of different professional groups. This chapter is concerned with one extreme of these interstitial specialisms. Chemical engineering – a subject that (...)

  48. A Commentary on Robin Hendry’s Views on Molecular Structure, Emergence and Chemical Bonding.Eric Scerri - 2023 - In João L. Cordovil, Gil Santos & Davide Vecchi (eds.), New Mechanism Explanation, Emergence and Reduction. Springer. pp. 161 - 177.
    In this article I examine several related views expressed by Robin Hendry concerning molecular structure, emergence and chemical bonding. There is a long-standing problem in the philosophy of chemistry arising from the fact that molecular structure cannot be strictly derived from quantum mechanics. Two or more compounds which share a molecular formula, but which differ with respect to their structures, have identical Hamiltonian operators within the quantum mechanical formalism. As a consequence, the properties of all such isomers yield precisely (...)

  49. Problem of the Direct Quantum-Information Transformation of Chemical Substance.Vasil Penchev - 2020 - Computational and Theoretical Chemistry eJournal (Elsevier: SSRN) 3 (26):1-15.
    Arthur Clark and Michael Kube–McDowell (“The Triger”, 2000) suggested the sci-fi idea about the direct transformation from a chemical substance to another by the action of a newly physical, “Trigger” field. Karl Brohier, a Nobel Prize winner, who is a dramatic persona in the novel, elaborates a new theory, re-reading and re-writing Pauling’s “The Nature of the Chemical Bond”; according to Brohier: “Information organizes and differentiates energy. It regularizes and stabilizes matter. Information propagates through matter-energy and mediates the (...)
