As we have seen, it was clearly Guyton's intention, in 1808, to supply details of his improved platinum pyrometer, and he did submit a drawing of the instrument at the meeting of the Class in December 1810. It would seem that on that occasion he did not supply those details which are to be found in the fourth, unpublished, part of the ‘Essay’. The existence of a text fit to be sent to the printer, and the execution of a (...) drawing relating to the improved version of his platinum pyrometer, might be taken as evidence that Guyton intended to publish. His paper of 1810 did not appear until 1814, however, so that publication of the fourth part of the ‘Essay’ could scarcely have occurred until 1815 or later. Guyton probably hoped to be able to read it to the Class of Physical and Mathematical Sciences before publishing it in the Annales de Chimie, but his death on 2 January 1816 robbed him of the opportunity.

An astonishing volume and diversity of evidence is available for many hypotheses in the biomedical and social sciences. Some of this evidence—usually from randomized controlled trials (RCTs)—is amalgamated by meta-analysis. Despite the ongoing debate regarding whether or not RCTs are the ‘gold-standard’ of evidence, it is usually meta-analysis which is considered the best source of evidence: meta-analysis is thought by many to be the platinum standard of evidence. However, I argue that meta-analysis falls far short of that standard. Different (...) meta-analyses of the same evidence can reach contradictory conclusions. Meta-analysis fails to provide objective grounds for intersubjective assessments of hypotheses because numerous decisions must be made when performing a meta-analysis which allow wide latitude for subjective idiosyncrasies to influence its outcome. I end by suggesting that an older tradition of evidence in medicine—the plurality of reasoning strategies appealed to by the epidemiologist Sir Bradford Hill—is a superior strategy for assessing a large volume and diversity of evidence.

The six platinum group metals (pgms: ruthenium, rhodium, palladium, osmium, iridium and platinum) posed a number of problems for 19th-century chemists, including Mendeleev, for their Periodic classification. This account discusses the discovery of the pgms, the determination of their atomic weights and their classification.

The purpose of this paper is to investigate the relationships between the so-called golden rule and the so-called platinum rule. According to the golden rule (GR) you ought to treat others as you want to be treated by them; and according to the platinum rule (PR), you ought to treat others as they want to be treated by you. In this essay I argue for the following propositions. (1) (GR) and (PR) are logically independent. (2) (PR) can be (...) derived from (GR) given that you want to be treated by others as they want to be treated by you. (3) (GR) is derivable from (PR) given that others want to be treated by you as you want to be treated by them. And (4) (GR) and (PR) are equivalent given that you want to be treated by others as they want to be treated by you, and others want to be treated by you as you want to be treated by them. I consider some possible interpretations of (GR) and (PR), and I also address the question of whether (GR) is more plausible than (PR) or vice versa, or whether they are complementary. I discuss one argument for the view that (PR) is better than (GR) and mention several arguments for the view that (GR) is better than (PR). The discussion suggests that (GR) and (PR) are complementary. (shrink)

"The golden rule" (Matthew 7:12) is a formulation of natural moral law, a logical way to divide good from evil. It has been attacked by J.W. Hennessey, Jr. and Bernard Gert as a "particularist preachment." On the contrary, it remains a useful, universal guide to moral conduct and cannot be considered a self-centered, subjective guide to the moral life. We must agree with Jeffrey Wattles that there are multiple possible meanings to the "rule", some legitimate and some spurious. The legitimate (...) meanings, such as the "standard of God-like behavior," all yield the same judgment on morally doubtful actions such as forgery. The so-called "platinum" rule, "Do unto others as they would have you do unto them" has face appeal, but is fatally flawed in its logic, and does not supercede "the golden rule" because part of the treatment I wish from others is a full understanding of my true needs and wishes, even when I do not judge my own needs correctly.

In lieu of an abstract, here is a brief excerpt of the content:Summary Of The Spoken Responses By The Poets To Their CriticsJohn HollanderMark Strand responded to Charles Berger’s comments by mak-ing appreciative remarks about the kind of attention his work had received, adding that he did occasionally in writing perceive “glimmers, in the kind of attention I pay, to what Charles Berger has spoken of.” With regard to certain aspects of prior intention, he said that “vague formal imperatives got (...) fulfilled in the writing” and that knowing at the time “the rightness of what I’ve said,” I was nonetheless able to “know the meaning of what I’d said only weeks afterward.” He also acknowledged the kinds of allusiveness which Berger had adduced in his writing, speaking of how and when in the course of writing the resources of his particular sort of echo and allusion seemed to make themselves available.He then turned to the specific question of one of the sequences of poems that Berger had discussed, the “Great Dog Poem No. 2.” He averred that in choosing a dog as speaker he had “not just meant to be funny” [he avowed later on in his remarks that his poems frequently began with “dark humor”] but had also sought for a mode of introspection more original than the fashionably solemn ones of so much contemporary poetry: “I could look within and bark.” With respect to the final line, he observed “I like to finish with a flourish, to pretend I’m Laforgue or Rimbaud,” manifesting “a desire to be a symbolist poet.” With respect to that concluding verse, “I feel like the end of a gorgeous line,” he added that if a dog said that—particularly “a [End Page 189] platinum retriever”—it could not be self-pitying. He spoke in general of the relation of high and low in the poem (a dog named “Rex,” and so forth) and of the relation of this sequence to a much earlier poem of his called “Eating Poetry” in which the speaker is likewise a dog.With regard to formal design, he concluded by saying that in general he tended to start poems “with rough drafts in blank verse” which he then “roughened up” in various ways, preferring as he said “cadences” rather than “measure” in the framing of lines. But he added that in the De Chirico poems he had read, he felt that if one wrote a villanelle, one should keep strictly to the form, without changing words in the refrain lines, and keeping to the iambic meter, saying that “I don’t think you should cheat” under those circumstances.Strand concluded by thanking Berger for the precise nature of his critical attentiveness.John Hollander started out by acknowledging with pleasure that Eleanor Cook’s analysis of his “Owl” had certainly helped him to understand it better; he observed that he felt he had only started to write what he called “real poetry” in his third book, when he had first written a poem he could not understand at the time, and only came to understand years later. He remarked that “The relation of poet and critic as framed by this panel is this: good criticism is a poem’s best friend. We all depend on our friends to point out to us things about ourselves we may not know or acknowledge; although their cousins and other familial relations are other poems, our poems’ best friends are pieces of critical writing.”He was particularly grateful to Cook for pointing out things he hadn’t himself seen—such as the question of the terminal words in the first stanza—but which as a result of the critical insight he had to acknowledge. And this brought up the crucial question of intentionality at the practical rather than theoretical level: in the case of such observations by critics and acknowledgments by poets, it would seem that the writing of a poem could have an intention of which the writer would be unaware. Hollander adduced the analogy of dreaming to poetic composition, paralleling the question “Did you mean to write that?” with (to anyone reporting a dream) “Did you mean to dream that?”He then observed about the...

The legal doctrine of ‘common purpose’ in South African criminal law considers all parties liable who have been in implicit or explicit agreement to commit an unlawful act, and associated with each other for that purpose, even if the consequential act has been carried out by one of them. It relieves the prosecution of proving the causal link between the conduct of an individual member of a group acting in common purpose, and the ultimate consequence caused by the action of (...) the group as a whole. The National Prosecuting Authority’s controversial and vociferously challenged decision to charge 270 demonstrators at Lonmin Platinum Mine in Marikana with the murders of 34 colleagues under the ‘common purpose’ doctrine, implying liability by association or agreement, raises the question as to the constitution and characteristics of the crowd and of the public, respectively. This article outlines the history of the application of the common purpose rule in South Africa, to then examine ‘common purpose’ within the philosophical parameters of group psychology and collective intentionality. It argues for methodological individualism within a psychoanalytic theorisation of group dynamics, and a non-summative approach to collective intentionality, in addressing some problems in the conceptualisation of group formation.

This article criticizes Mathias Risse and Richard Zeckhauser's recent utilitarian defense of racial profiling. I use a novel thought-experiment to argue that even if a negative phenomenon could be reduced by profiling members of certain groups who happen to be disproportionately associated with it, the practice can be implausible. Specifically, I explore the possibility that in a given society, platinum blondes have a higher per capita incidence of a serious sexually transmitted disease, D. And I argue that doctors and (...) health officials in the society would not be justified in profiling such blondes, given that there is nothing about being a platinum blonde that causes one to have D.

We discuss two research projects in material science in which the results cannot be stated with an estimation of the error: a spectroscopic ellipsometry study aimed at determining the orientation of DNA molecules on diamond and a scanning tunneling microscopy study of platinum-induced nanowires on germanium. To investigate the reliability of the results, we apply ideas from the philosophy of models in science. Even if the studies had reported an error value, the trustworthiness of the result would not depend (...) on that value alone. (shrink)

Through engaging interviews, testimonials, and anecdotes from photographers, curators, printers, and colleagues, Object Lesson: On the Influence of Richard Benson pays homage to a legendary figure whose name is synonymous with the evolving history and philosophy of photographic reproduction. From making platinum prints for Paul Strand and books with Lee Friedlander to his own experiments with inkjet and digital offset processes, and as a teacher and dean of the Yale School of Art, by the time of his death in (...) 2017, Benson had inspired over three decades of students and artisans through his mentorship and work. In words and images, Object Lesson stands as a testament to Benson's wit, wisdom, and incomparable obsession with how photographic images render and connect us to the world. (shrink)

In the course of his chemical investigation of crude platina ore, William Hyde Wollaston in 1802 isolated and characterized the metal palladium. In early 1803, he chose to make known his discovery by offering small samples of the metal for sale through a small shop in London. In the notice advertising the properties of the new metal, no information was given as to its source nor to its discoverer. The unique properties of the metal, and the secrecy surrounding its discovery, (...) led the Irish chemist Richard Chenevix to question the elemental nature of the new metal. His hasty but extensive investigation of the chemical properties of palladium convinced him that it was no more than an alloy of platinum and mercury, and he denounced the discovery as fraudulent. The president of the Royal Society, Joseph Banks, was drawn into the resulting furore, and correspondence between him and Chenevix reveals involved plans to obtain the identity of the palladium discoverer. The controversy is viewed as a significant episode in the continuing debate in the chemical community over the operational definition of a chemical element, and although Chenevix's concern over the growth in the number of new elements was justified, his choice of palladium as a test case was an unfortunate one, for his claim that the metal was an alloy was found to be erroneous. Motives for the actions of both Chenevix and Wollaston are sought, and the judgement that their careers were damaged by the incident is questioned. (shrink)

Cytoskeletal organization in embryonic skeletal muscle cells has been examined by transmission electron microscopy; the technique involves preparation using the platinum replication method of freezedried samples, with and without cryofracture. The cytoskeletons in developing muscle cells appear to play a role in preserving cell shape as well as in anchoring myofibrils to cell membrane.

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 its valence shell which makes one of its excited states to be a closed 5d10–6s0 state. Surely this state would not be expected to be crucial to the catalytic activity of platinum, or would it? Or take palladium whose ground state is precisely the 4d10–5s0 state, should we expect that an isolated Pd atom at near zero-point temperature would attack a closed-shell hydrogen molecule efficiently? We shall here show that this is precisely the case; the closed-shell excited states of nickel and platinum are indeed crucial, through symmetry avoided crossings, for their reactivity. Other valuable catalysts as ruthenium depend on their excited states with maximal d-shell occupancy for their activity. The most notable confirmation of this new finding; that closed d-shells are vital to the catalytic activity of noble metals however, is the case of palladium whose closed-shell ground state is indeed capable of attacking hydrogen and hydrocarbon molecules even at temperatures well below 10 K as was predicted theoretically and immediately confirmed experimentally.

According to HealthCare.gov, by improving access to quality health for all Americans, the Affordable Care Act (ACA) will reduce disparities in health insurance coverage. One way this will happen under the provisions of the ACA is by creating a new health insurance marketplace (a health insurance exchange) by 2014 in which “all people will have a choice for quality, affordable health insurance even if a job loss, job switch, move or illness occurs”. This does not mean that everyone will have (...) whatever insurance coverage he or she wants. The provisions of the ACA require that each of the four benefit categories of plans (known as bronze, silver, gold and platinum) provides no less than the benefits available in an “essential health benefits package”. However, without a clear understanding of what criteria must be satisfied for health care to be essential, the ACA’s requirement is much too vague and open to multiple, potentially conflicting interpretations. Indeed, without such understanding, in the rush to provide health insurance coverage to as many people as is economically feasible, we may replace one kind of disparity (lack of health insurance) with another kind of disparity (lack of adequate health insurance). Thus, this paper explores the concept of “essential benefits”, arguing that the “essential health benefits package” in the ACA should be one that optimally satisfies the basic needs of the people covered.

Japanese rank among the least likely to intervene to help a stranger in a non-emergency situation while Americans rank among the most likely. Across four studies, we demonstrate that Japanese are less likely to offer help to strangers because their decisions rely more heavily on the assessment of the needs of others. Accordingly, when there is uncertainty about the need for help, Japanese are less likely to intervene than Americans because without an understanding of the needs of recipient, the impact (...) of intervention may also be harmful. When the situation is unambiguous, Japanese and Americans are equally likely to help. This divergence in readiness to help strangers elaborates the understanding of why people in Japanese contexts are more likely than those in United States contexts to attend to the situation and to avoid uncertain situations. It also illuminates cultural differences in models of agency—implicit understandings of when and why a person should act to aid another. (shrink)
