Diagonal relationships in the periodic table were recognized by both Mendeléev and Newlands. More appropriately called isodiagonal relationships, the same three examples of lithium with magnesium, beryllium with aluminum, and boron with silicon, are commonly cited. Here, these three pairs of elements are discussed in detail, together with evidence of isodiagonal linkages elsewhere in the periodic table. General criteria for defining isodiagonality are proposed.

As part of a series of contributions on patterns in the periodic table, the relationships among the transition metals are examined here in a systematic manner. It is concluded that the traditional method of categorizing transition elements by group or by period is not as valid as by using combinations thereof. From chemical similarities, it is proposed that the transition metals be considered as the [V–Cr–Mn] triad; the [Fe–Co–Ni–Cu] tetrad; the [Ti–Zr–Hf–Nb–Ta] pentad; the [Mo–W–Tc–Re] tetrad; and the [Ru–Os–Rh–Ir–Pd–Pt–Au] heptad. Silver (...) does not fit neatly in anywhere and is better linked with thallium. (shrink)

Over the last two hundred years, there have been many occasions where the name of a newly-discovered element has provoked controversy and dissent but in modern times, the naming of elements after scientists has proved to be particularly contentious. Here we recount the threads of this story, predominantly through discourses in the popular scientific journals, the first major discussion on naming an element after a scientist ; the first definitive naming after a scientist ; and the first naming after a (...) living scientist.

Similarities in properties among pairs of metallic elements and their compounds in the lower-right quadrant of the Periodic Table have been named the ‘Knight’s Move’ relationship. Here, we have undertaken a systematic study of the only two ‘double-pairs’ of ‘Knight’s Move’ elements within this region: copper-indium/indium-bismuth and zinc-tin/tin-polonium, focussing on: metal melting points; formulas and properties of compounds; and melting points of halides and chalcogenides. On the basis of these comparisons, we conclude that the systematic evidence for ‘Knight’s Move’ relationships (...) derives from similarities in formulas and properties of matching pairs of compounds in the same oxidation state. Physical properties, such as melting points, do not provide consistent patterns and trends and hence should not be considered as a common characteristic of this relationship. (shrink)

The usefulness of isoelectronic series (same number of total electrons and atoms and of valence electrons) across Periods is often overlooked. Here we show the ubiquitousness of isoelectronic sets by means of matrices, arrays, and sequential series. Some of these series have not previously been identified. In addition, we recommend the use of the term valence-isoelectronic for species which differ in the number of core electrons and pseudo-isoelectronic for matching (n) and (n + 10) species.

The early Periodic Tables displayed an 8-Group system. Though we now use an 18-Group array, the old versions were based on evidence of similarities between what we now label as Group (n) and the corresponding Group (n + 10). As part of a series on patterns in the Periodic Table, in this contribution, these similarities are explored for the first time in a systematic manner. Pourbaix (Eh–pH) diagrams have been found particularly useful in this context.

In a recent paper, Pickel and Rabern (2016) argue that a dynamic Tarskian semantics resolves Fine’s antinomy of the variable without the radical consequences for semantics proposed by Fine (2003, 2007). While Pickel and Rabern’s basic insight—a parameter of discourse context that tracks occurrences of variable-binding expressions—is important, I will argue that their own Tarskian theory faces a destructive dilemma: either their theory does not resolve Fine’s antinomy as they propose, or their theory does not reflect the intuitive motivation for (...) what they call structured meanings. I suggest that in response to this dilemma we should reject one of the principles that generates Pickel and Rabern’s version of the antinomy. Here Pickel and Rabern’s insight has surprising, but salutary, foundational consequences for semantics. (shrink)

A Managerial Philosophy of Technology offers a unique combination of a review of academic work in the philosophy of technology with practical methodologies for business management of technology strategy.

Transcending Subjects: Augustine, Hegel and Theology engages the seminal figures of Hegel and Augustine around the theme of subjectivity, with consideration toward the theology and politics of freedom.

Derided and disregarded by many of his contemporaries, Michel Foucault is now regarded as probably the most influential thinker of the twentieth century, his work is studied across the humanities and social sciences. Reading Foucault, however, can be a challenge, as can writing about him, but in Understanding Foucault, the authors offer an entertaining and informative introduction to his thinking. They cover all the issues Foucault dealt with, including power, knowledge, subjectivity and sexuality and discuss the development of his analysis (...) throughout his work. (shrink)

A symposium was held at the Centre for Research in the Arts, Social Sciences and Humanities at the University of Cambridge on June 12th 2019, ‘Rethinking Repetition in a Digital Age’, at which Geoff Stead, a leading mobile tech designer, was a keynote speaker. The focus of the Cambridge UK event was on how the potentials of digital technologies—whose harms have received widespread attention—could be redirected for the social good. For Stead, this is precisely what Babbel are doing in (...) their approach to commercial digital language learning. Stead spoke to the idea of reversing our personal relationships to mechanical affordances, and finding empowerment in understanding their designed logics. The transcript of the interview below, made in October 2021, revisits some of the main points he raised at that event. (shrink)

Dismissed as a miserable elitist who condemned popular culture in the name of 'high art', Theodor W. Adorno (1903–1969) is one of the most provocative and important yet least understood of contemporary thinkers. This book challenges this popular image and re-examines Adorno as a utopian philosopher who believed authentic art could save the world. Adorno Reframed is not only a comprehensive introduction to the reader coming to Adorno for the first time, but also an important re-evaluation of this founder of (...) the Frankfurt School. Using a wealth of concrete illustrations from popular culture, Geoffrey Boucher recasts Adorno as a revolutionary whose subversive irony and profoundly historical aesthetics defended the integrity of the individual against social totality.

Contextualism in epistemology has traditionally been understood as the view that “know” functions semantically like an indexical term, encoding different contents in contexts with different epistemic standards. But the indexical hypothesis about “know” faces a range of objections. This article explores an alternative version of contextualism on which “know” is a semantically stable term, and the truth-conditional variability in knowledge claims is a matter of pragmatic enrichment. The central idea is that in contexts with stringent epistemic standards, knowledge claims are (...) narrowed: “know” is used in such contexts to make assertions about particularly demanding types of knowledge. The resulting picture captures all of the intuitive data that motivate contextualism while sidestepping the controversial linguistic thesis at its heart. After developing the view, the article shows in detail how it avoids one influential linguistic objection to traditional contextualism concerning indirect speech reports, and then answers an objection concerning the unavailability of certain types of clarification speeches.

This paper argues against the view that trolley cases are of little or no relevance to the ethics of automated vehicles. Four arguments for this view are outlined and rejected: the Not Going to Happen Argument, the Moral Difference Argument, the Impossible Deliberation Argument and the Wrong Question Argument. In making clear where these arguments go wrong, a positive account is developed of how trolley cases can inform the ethics of automated vehicles.

Traditional approaches tend to regard figuration (and by extension, deference in general) as an essentially marked or playful use of language, which is associated with a pronounced stylistic effect. For linguistic purposes, however, there is no reason for assigning a special place to deferred uses that are stylistically notable — the sorts of usages that people sometimes qualify with a phrase like "figuratively speaking." There is no important linguistic difference between using redcoat to refer to a British soldier and using (...) suit to refer to a corporate executive (as in "A couple of suits stopped by to talk about the new products"). What creates the stylistic effect of the latter is not the mechanism that generates it, but the marked background assumptions that license it — here, the playful presupposition that.. (shrink)

The phenomenon of systematic polysemy offers a fruitful domain for examining the theoretical differences between lexicological and lexicographic approaches to description. We consider here the process that provides for systematic conversion of count to mass nouns in English (a chicken Æ chicken, an oak Æ oak etc.). From the point of view of lexicology, we argue, standard syntactic and pragmatic tests suggest the phenomenon should be described by means of a single unindividuated transfer function that does not distinguish between interpretations (...) (rabbit = "meat" vs. "fur"). From the point of view of lexicography, however, these pragmatically determined"sense precisions" are made part of explicit description via the inclusion of semantic "licenses," a mechanism distinct from lexical rules.

Transitional justice scholars are increasingly concerned with measuring the impact of transitional justice initiatives. Scholars often assume that TJ mechanisms must be properly designed and ordered to achieve lasting effect, but the impact of TJ timing and sequencing has attracted relatively little theoretical or empirical attention. Focusing on Latin America, this article explores variation within the region as to when TJ occurs and the order in which mechanisms are implemented. We utilize qualitative comparative analysis to assess the impact of TJ (...) timing and sequencing on democratic development. We find little evidence for path dependency owing to the chronological order of mechanisms. We do find, however, that amnesties and trials approach a sufficient condition for democratic consolidation in Latin America; trials, however, come closest to being a necessary condition for successful democratic consolidation.

All aspects of the concept of collocation – the phenomenon whereby words naturally tend to occur in the company of a restricted set of other words – are covered in this book. It deals in detail with the history of the word collocation, the concepts associated with it and its use in a linguistic context. The authors show the practical means by which the collocational behavior of words can be explored using illustrative computer programs and examine applications in teaching, lexicography (...) and natural language processing that use collocation in formation. The book investigates the place that collocation occupies in theories of language and provides a thoroughly comprehensive and up-to-date survey of the current position of collocation in language studies and applied linguistics.

Even if our justified beliefs are closed under known entailment, there may still be instances of transmission failure. Transmission failure occurs when P entails Q, but a subject cannot acquire a justified belief that Q by deducing it from P. Paradigm cases of transmission failure involve inferences from mundane beliefs (e.g., that the wall in front of you is red) to the denials of skeptical hypotheses relative to those beliefs (e.g., that the wall in front of you is not white (...) and lit by red lights). According to the Bayesian explanation, transmission failure occurs when (i) the subject’s belief that P is based on E, and (ii) P(Q|E) P(Q). No modifications of the Bayesian explanation are capable of accommodating such cases, so the explanation must be rejected as inadequate. Alternative explanations employing simple subjunctive conditionals are fully capable of capturing all of the paradigm cases, as well as those missed by the Bayesian explanation. (shrink)

The Thousands of Problems for Theorem Provers (TPTP) World is a well-established infrastructure that supports research, development and deployment of automated theorem proving systems. This paper provides an overview of the logic languages of the TPTP World, from classical first-order form (FOF), through typed FOF, up to typed higher-order form, and beyond to non-classical forms. The logic languages are described in a non-technical way and are illustrated with examples using the TPTP language.

Karl Popper is a philosopher of knowledge and politics, rationality and freedom. His ideas have won acceptance and provoked controversy among an academic as well as a more general audience. This book aims to broaden our understanding of Popper's philosophy. It is one of the few studies to present his work as an evolving "system of ideas", and to take account of the full range of his writings. The book discusses Popper's early philosophy of politics, science and social science, as (...) well as his later philosophy, which offers an evolutionary account of human nature and the growth of knowledge. Contrary to many earlier interpretations, Stokes argues that we should look to Popper's political values to understand the unity of his work and the evolution of his theory of knowledge and general philosophy. The chapters in this book examine Popper's arguments, and offer critical analysis of the achievements and shortcomings of his philosophy. In particular, Stokes considers the problems of rationality, politics and ethics in the context of debates between the Frankfurt School of critical theory and critical rationalism. The book will be of interest to second-year undergraduates and above in the fields of philosophy and critical theory. (shrink)

Whether it seems that you know something depends in part upon practical factors. When the stakes are low, it can seem to you that you know that p, but when the stakes go up it'll seem to you that you don't. The apparent sensitivity of knowledge to stakes presents a serious challenge to epistemologists who endorse a stable semantics for knowledge attributions and reject the idea that whether you know something depends on how much is at stake. After arguing that (...) previous attempts to meet this challenge fall short, I offer a new solution: the unassertability account. The account starts with the observation that high stakes subjects aren't in an epistemic position to assert. We generally presuppose that knowing is sufficient for epistemically proper assertion, but this presupposition only stands up to scrutiny if we draw a distinction between two notions of epistemic propriety, and we shouldn't expect ordinary speakers to draw it. A subject in a high stakes situation who fails to draw the distinction will be led by the sufficiency claim to treat anything she isn't in a position to assert as something she isn't in a position to know. The sensitivity of epistemically proper assertion to practical factors explains the merely apparent sensitivity of knowledge to stakes. (shrink)

Demonstratives and Indexicals In the philosophy of language, an indexical is any expression whose content varies from one context of use to another. The standard list of indexicals includes pronouns such as “I”, “you”, “he”, “she”, “it”, “this”, “that”, plus adverbs such as “now”, “then”, “today”, “yesterday”, “here”, and “actually”. Other candidates include the tenses … Continue reading Demonstratives and Indexicals →.

BackgroundAssisted dying has wide support among the general population but there is evidence that those providing care for the dying may be less supportive. Senior doctors would be involved in implementing the proposed change in the law. We aimed to measure support for legalising physician assisted dying in a representative sample of senior doctors in England and Wales, and to assess any association between doctors' characteristics and level of support for a change in the law.MethodsWe conducted a postal survey of (...) 1000 consultants and general practitioners randomly selected from a commercially available database. The main outcome of interest was level of agreement with any change in the law to allow physician assisted suicide.ResultsThe corrected participation rate was 50%. We analysed 372 questionnaires. Respondents' views were divided: 39% were in favour of a change to the law to allow assisted suicide, 49% opposed a change and 12% neither agreed nor disagreed. Doctors who reported caring for the dying were less likely to support a change in the law. Religious belief was also associated with opposition. Gender, specialty and years in post had no significant effect.ConclusionMore senior doctors in England and Wales oppose any step towards the legalisation of assisted dying than support this. Doctors who care for the dying were more opposed. This has implications for the ease of implementation of recently proposed legislation. (shrink)

The concept of integration has garnered increased attention in the past few years, despite a long history of only brief mention. Integration services are offered by therapists, coaches, and other practitioners, or may be self-guided. There are many definitions of psychedelic integration, and the term encompasses a range of practices and techniques. This seems to have led to confusion about what integration is and how it is best practiced. The primary focus of this manuscript is the presentation of the first (...) extensive review and concept analysis of definitions, practices, and models of psychedelic integration. We provide a synthesized definition of integration, synthesized model of integration, and comprehensive summary of integration practices to bring clarity to the subject. (shrink)

The use of machine learning systems for decision-support in healthcare may exacerbate health inequalities. However, recent work suggests that algorithms trained on sufficiently diverse datasets could in principle combat health inequalities. One concern about these algorithms is that their performance for patients in traditionally disadvantaged groups exceeds their performance for patients in traditionally advantaged groups. This renders the algorithmic decisions unfair relative to the standard fairness metrics in machine learning. In this paper, we defend the permissible use of affirmative algorithms; (...) that is, algorithms trained on diverse datasets that perform better for traditionally disadvantaged groups. Whilst such algorithmic decisions may be unfair, the fairness of algorithmic decisions is not the appropriate locus of moral evaluation. What matters is the fairness of final decisions, such as diagnoses, resulting from collaboration between clinicians and algorithms. We argue that affirmative algorithms can permissibly be deployed provided the resultant final decisions are fair. (shrink)

In his excellent essay, ‘Nudges in a post-truth world’, Neil Levy argues that ‘nudges to reason’, or nudges which aim to make us more receptive to evidence, are morally permissible. A strong argument against the moral permissibility of nudging is that nudges fail to respect the autonomy of the individuals affected by them. Levy argues that nudges to reason do respect individual autonomy, such that the standard autonomy objection fails against nudges to reason. In this paper, I argue that Levy (...) fails to show that nudges to reason respect individual autonomy. (shrink)

This article holds that governmental investments in quantum technologies speak to the imaginable futures of digital sovereignty and digital infrastructures, two major areas of change driven by related technologies like AI and Big Data, among other things, in international law today. Under intense development today for future interpolation into digital systems that they may alter, quantum technologies occupy a sort of liminal position, rooted in existing assemblages of computational technologies while pointing to new horizons for them. The possibilities they raise (...) are neither certain nor determinate, but active investments in them (legal, political and material investments) offer perspective on digital technology-driven influences on an international legal imagination. In contributing to visions of the future that are guiding ambitions for digital sovereignty and digital infrastructures, quantum technologies condition digital technology-driven changes to international law and legal imagination in the present. Privileging observation and description, I adapt and utilize a diffractive method with the aim to discern what emerges out of the interference among the several related things assembled for this article, including material technologies and legal institutions. In conclusion, I observe ambivalent changes to an international legal imagination, changes which promise transformation but appear nonetheless to reproduce current distributions of power and resources.
