Obtaining consent for medical treatment in older adults raises a number of complex challenges. Despite being required by ethics and the law, consent for medical treatment is not always validly sought in this population. The dynamic nature of capacity, particularly in individuals who have dementia or other cognitive impairments, adds complexity to obtaining consent. Further challenges arise in ensuring that older people comprehend the medical treatment information provided and that consent is not vitiated by coercion or undue influence. Existing mechanisms (...) to address issues surrounding consent for older adults only address incapacity and raise further challenges. As the ageing population increases, these issues are likely to become more profound, thus action is required to address these challenges. Raising awareness, more education, engaging with people with dementia, and conducting further research would assist in beginning to overcome these challenges. (shrink)

ABSTRACT The main cause of the crisis was the behavior of the banks—largely a result of misguided incentives unrestrained by good regulation. Conservative ideology, along with unrealistic economic models of perfect information, perfect competition, and perfect markets, fostered lax regulation, and campaign contributions helped the political process along. The banks misjudged risk, wildly overleveraged, and paid their executives handsomely for being short‐sighted; lax regulation let them get away with it—putting at risk the entire economy. The mortgage brokers neglected due diligence, (...) since they would not bear the risk of default once their mortgages had been securitized and sold to others. Others can be blamed: the ratings agencies that judged subprime securities as investment grade; the Fed, which contributed low interest rates; the Bush administration, whose Iraq war and tax cuts for the rich made low interest rates necessary. But low interest rates can be a boon; it was the financial institutions that turned them into a bust. (shrink)

What, precisely, is `salt'? It is a certainwhite, solid, crystalline, material, alsocalled sodium chloride. Does any of that solidwhite stuff exist in the sea? – Clearly not.One can make salt from sea water easily enough,but that fact does not establish thatsalt, as such, is present in brine. (Paper andink can be made into a novel – but no novelactually exists in a stack of blank paper witha vial of ink close by.) When salt dissolves inwater, what is present is no (...) longer `salt' butrather a collection of hydrated sodium cationsand chloride anions, neither of which isprecisely salt, nor is the collection. Theaqueous material in brine is also significantlydifferent from pure water. Salt may beconsidered to be present in seawater, but onlyin a more or less vague `potential' way.Actually, there is no salt in the sea. In bothancient and modern treatments of otherimportant chemical concepts, including thenotions of `element', related complication,especially polysemy (terms with multiplemeanings), also occurs.In a recent paper, Paul Needham discussed the(predicable) properties of chemical substances,phases, and solutions. He provided a valuablecharacterization of cases in which severalquantities occupy the same space. He alsoconcluded that solution properties are not`intensive', because solvent and solute do nothave parts in common. He tacitly assumed thatingredients are not altered by their inclusionin a solution. This may be the case in somespecial cases (deutero-benzene dissolved inbenzene, say) but is not true in general – andcertainly does not apply to the case of brine,which Needham used as an example – since theions that exist in the solution, and also theaqueous material there, are quite differentfrom the pure ingredients used in making thesolution. An adequate theory of wholes andparts (mereology) must take into account thatwhen individuals enter combinations ofinteresting sorts they no longer are the verysame individuals that existed prior to thecomposition. It appears that no such formaltheory now actually exists. (shrink)

In the characterization of the ArCl2 'van der Waals complex', a recognizable pattern of well-defined peaks is observed in the microwave absorption spectrum. In the control of chaos in a chemical oscillatory reaction the power spectrum progressively becomes simpler, at length yielding a single peak. Since both of these cases generate coherences that are centers of agency, they should be considered to produce new chemical entities. Applicability of this ontological approach to coherences of wider societal interest is suggested.

In 1931 eminent chemist Fritz Paneth maintained that the modern notion of “element” is closely related to (and as “metaphysical” as) the concept of element used by the ancients (e.g., Aristotle). On that basis, the element chlorine (properly so-called) is not the elementary substance dichlorine, but rather chlorine as it is in carbon tetrachloride. The fact that pure chemicals are called “substances” in English (and closely related words are so used in other European languages) derives from philosophical compromises made by (...) grammarians in the late Roman Empire (particularly Priscian [fl. ~520 CE]). When the main features of the constitution of isotopes became clear in the first half of the twentieth century, the formal (IUPAC) definition of a “chemical element” was changed. The features that are “essential” to being an element had previously been “transcendental” (“beyond the sphere of consciousness”) but, by the mid-twentieth century the defining characteristics of elements, as such, had come to be understood in detail. This amounts to a shift in a “horizon of invisibility” brought about by progress in chemistry and related sciences. Similarly, chemical insight is relevant to currently-open philosophical problems, such as the status of “the bundle theory” of the coherence of properties in concrete individuals. (shrink)

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 (...) interest to chemists generally are metastable . In many cases chemical systems of a given elemental composition may exist in any one of several different metastable states depending on the history of the system. Molecular structure generally depends on contingent historical circumstances of synthesis and separation, rather than solely or mainly on relative energies of alternative stable states, those energies in turn determined by relationships among components. Chemical structure is usually ‘kinetically-determined’ rather than ‘thermodynamically-determined.’ For instance, cyclical hydrocarbon ring-systems (as in cyclopropene) are produced only in special circumstances. Adequate theoretical treatments must take account of the persistent effects of such contingent historical events whenever they are relevant—as they generally are in chemistry. (shrink)

One of the main functions that introductory chemistry courses have fulfilled during the past century has been to provide evidence for the general validity of 'the atomic hypothesis.' A second function has been to demonstrate that an analytical approach has wide applicability in rationalizing many kinds of phenomena. Following R.G. Collingwood, these two functions can be recognized as related to a philosophical 'cosmology' (worldview, weltanshauung) that became dominant in the later Renaissance. Recent developments in many areas of science, and in (...) chemistry, have emphasized the central importance of understanding synthetic, developmental, and evolutionary aspects of nature. This paper argues that these scientific developments, and changes in other aspects of culture, amount to a widespread shift to an alternative cosmology, a quite different general worldview. To the extent that this is the case, introductory chemistry courses ought to be changed in fundamental ways. Rather that having a main focus on analysis to microscopic components, introductory chemistry instruction should emphasize current scientific understanding of the (synthetic) evolutionary origins of the present world. This altered approach would provide good preparation for future professional work, while also making better contact with the perceived concerns of students. (shrink)

Nature abounds in compound individuals. Discrete, functioning entities are made up of components which are, in some sense, also individuals. Scientists sometimes need to be concerned with whether aggregates (e.g.. species of plants) or components (e.g., quarks) exist. but such questions are not generally regarded as having great importance for science. It has often happened, however, that scientific developments have had major significance for subsequent philosophical discussion of problems of the one and the many. Recently, there has been considerable increase (...) in scientific understanding of spontaneous development of spatial and temporal organization (structure) in physical. chemical, and biological systems. In an earlier note (PS 11:35), I suggested that this progress in science raises points that may be helpful in dealing with a question of current importance for process philosophy. This paper provides support for that suggestion. The first section introduces the philosophical problem. The middle sections provide brief non-technical introduction to scientific concepts. The final section combines both topics. (shrink)

Combinations of molecules, of biological individuals, or of chemical processes can produce effects that are not simply attributable to the constituents. Such non-redundant causality warrants recognition of those coherences as ontologically significant whenever that efficacy is relevant. With respect to such interaction, the effective coherence is more real than are the components. This ontological view is a variety of structural realism and is also a kind of process philosophy. The designation ‘process structural realism’ (PSR) seems appropriate.

This article grapples with the causes of India’s microfinance crisis. By contrasting Bangladesh’s highly successful Grameen model with the allegedly “universalizable” version of India’s SKS Microfinance, trust or social capital is isolated—not just narrowly interpreted within standard economic theory, but more broadly construed—as the essential element accounting for the early success of microfinance. It is argued that the microfinance experience has been widely misinterpreted, in both analytical and policy terms. This article suggests inherent limits in extending the model to for-profit (...) institutions and, in particular, to the pace of scaling up. (shrink)

'Fear' is used scientifically in two ways, which causes confusion: it refers to conscious feelings and to behavioral and physiological responses. Restricting the use of 'fear' to denote feelings and using 'threat-induced defensive reactions' for the responses would help avoid misunderstandings about the brain mechanisms involved.

While it is common to think that neuroscientists are proponents of basic emotions theory, this is not necessarily the case. My ideas, for example are more aligned with cognitive than basic emotions theories.

This paper recommends that chemistry educators shift to a different ‘idea of nature’, an alternative ‘worldview.’ Much of contemporary science and technology deals in one way or another with dynamic coherences that display novel and important properties. The notion of how the world works that such studies and practices generate (and require) is quite different from the earlier concepts that are now integrated into science education. Eventual success in meeting contemporary technological and social challenges requires general diffusion of an overall (...) outlook that focuses on creative generation of novel and useful coherences, replacing a worldview that concentrates on analysis of pre-existing items to minimum constituents. Such a shift in emphasis would amount to general adoption of a new basic model of how nature functions. Chemistry educators can and should provide leadership for this urgently-needed development.

During a long and distinguished career, Belgian physical chemist Ilya Prigogine (1917–2003) pursued a coherent research program in thermodynamics, statistical mechanics, and related scientific areas. The main goal of this effort was establishing the origin of thermodynamic irreversibility (the ‘‘arrow of time’’) as local (residing in the details of the interaction of interest), rather than as global (being solely a consequence of properties of the initial singularity – the ‘‘Big Bang’’). In many publications for general audiences, he stated the opinion (...) that this scientific research had great philosophical importance. Prigogine and his colleagues considered that the most recent stages of this research program have been successful, so that the local origins of the arrow of time are now established. There is no scientific consensus as to whether or not this claim is valid. Similarly, there is no consensus on whether the competing global (initial singularity) explanation has been proven.

While engaging in rich discussion, Conspiracy Theories analyzes current arguments and evidence while providing real-world examples so students can contextualize and visualize the debates. Each chapter addresses important current questions, provides conceptual tools, defines important terms, and introduces the appropriate methods of analysis.

Aware of the decline and imminent demise of many integrated steel mills in the United States and fascinated by their monumental architecture, machinery, and the culture of work and community that was inextricably connected to them, Joseph Elliott photographed the mills in Bethlehem, Pennsylvania from 1989 until final shutdown in 1997. This book appeals to the growing fascination with industrial archaeology and will be an inspiration for the preservation and re-use of these relic structures.

Are the conclusions reached by mature sciences merely “likely stories” or are they “really true”? Questions of this sort have been live issues from Étienne Tempier’s March 1277 condemnation of theses of the Radical Aristotelians of Paris to the May 2005 Kansas State Board of Education deliberations on Darwinism. One major difficulty with the view that scientific findings are “really true” is that, from the historical record, all such statements are recognized as being revisable, even replaceable. Several attempts to formalize (...) a notion of “approximate truth” have addressed this difficulty—without notable success. This book proposes a new solution to the problem—a resolution that stands in the tradition of the American Pragmatists: Peirce, James, and Dewey. (shrink)

The main idea in this series of essays is that subjective awareness depends upon the intralaminar nuclei of each thalmus. This implies that the internal structure and external relations of ILN make subjective awareness possible. An array of material relevant to this proposal was briefly reviewed in Part I. This Part II considers in more detail some semantic aspects and a bit of philosophic background as these pertain to propositions 0, 1, and 2 of Part I. Part II should be (...) read in conjunction with Part I. (shrink)
