Is the quantum-logic interpretation dead? Its near total absence from current discussions about the interpretation of quantum theory suggests so. While mathematical work on quantum logic continues largely unabated, interest in the quantum-logic interpretation seems to be almost nil, at least in Anglo-American philosophy of physics. This paper has the immodest purpose of changing that fact. I shall argue that while the quantum-logic interpretation faces challenges, it remains a live option. The usual objections either miss the mark, or admit a (...) reasonable answer, or fail to decide the issue conclusively. (shrink)

Addressing a wide range of topics, from Newton to Post-Kuhnian philosophy of science, these essays critically examine themes that have been central to the influential work of philosopher Michael Friedman.

The purpose of this book is to discuss some critical components of Albert Shanker's work in American education, first as a teacher, then as president of the AFT. This is done in the context of the developments that took place in the United States since 1902 and the formation of the AFT in 1916. It focuses on the elements of leadership that were critical to the development of the United States from that time to the present. It presents these developments (...) in the context of Shanker's involvement since 1964. It also focuses on the dynamics of human relations cast in institutional settings. In doing so it presents features of a nation as it struggled with economic, social, and political issues that make society what it is. This discussion is done as a reflection of the need to strengthen democracy. The relations that Shanker has had with other people and organizations forms a critical component of the study. (shrink)

This paper proposes a logic, motivated by modal interpretations, in which every quantum mechanics propositions has a truth-value. This logic is completely classical, hence violates the conditions of the Kochen-Specker theorem. It is shown how the violation occurs, and it is argued that this violation is a natural and acceptable consequence of modal interpretations. It is shown that despite its classicality, the proposed logic is empirically indistinguishable from quantum logic.

This essay looks to re-evaluate sculptor Richard Serra’s famous claim that “to remove the work is to destroy it.” Using OOO, and particularly Graham Harman’s interpretation of Martin Heidegger’s tool analysis, in order to analyze the now famous moment when Tilted Arc was de-installed from Federal Plaza, Manhattan in 1989, this paper argues that the work was not in fact destroyed but rather that its ontological autonomy was even more absolutely revealed in that moment as such. Although it is the (...) case that art objects and sites are prone to discursive co-construction and evaluation, it is this analysis’ claim that they both are possessive of a deep, substantive form also, a form resistant to appropriation. Tilted Arc therefore revealed something even more insidious and dangerous to those who opposed it than the power of art to speak back to its surroundings. Rather, it uncovered the substantive objecthood of the site itself. (shrink)

BackgroundTo limit selective and incomplete publication of the results of clinical trials, registries including ClinicalTrials.gov were introduced. The ClinicalTrials.gov registry added a results database in 2008 to enable researchers to post the results of their trials as stipulated by the Food and Drug Administration Amendment Act of 2007. This study aimed to determine the direction and magnitude of any change in publication proportions of registered breast cancer trials that occurred since the inception of the ClinicalTrials.gov results database.MethodsA cross-sectional study design (...) was employed using ClinicalTrials.gov, a publicly available registry/results database as the primary data source. Registry contents under the subcategories ‘Breast Neoplasms’ and ‘Breast Neoplasms, Male’ were downloaded on 1 August 2015. A literature search for included trials was afterwards conducted using MEDLINE and DISCOVER databases to determine publication status of the registered breast cancer trials.ResultsNearly half (168/340) of the listed trials had been published, with a median time to publication of 24 months (Q1 = 14 months, Q3 = 42 months). Only 86 trials were published within 24 months of completion. There was no significant increase in publication proportions of trials that were completed before the introduction of the results database compared to those completed after (OR = 1.00, 95 % CI =.61 to 1.63; adjusted OR = 0.84, 95 % CI =.51 to 1.39). Characteristics associated with publication included trial type (observational versus interventional adjusted OR =.28, 95 % CI =.10 to.74) and completion/termination status (terminated versus completed adjusted OR =.22, 95 % CI =.09 to.51).ConclusionsLess than a half of breast cancer trials registered in ClinicalTrials.gov are published in peer-reviewed journals.

The master narrative of Apartheid South Africa created a specific identity for white boys and men and, together with this identity, a very particular role and place within the South African context. This identity was exemplified in the men who were conscripted into the military from 1967 until 1994, and who participated in operations on the border regions of Namibia and Angola as well as within local townships in the war of liberation against apartheid and minority rule. Many veterans have (...) been left grappling not only with the traumas associated with combat but also with the loss of their identities as war heroes in a country under changed political control. As a result, many of their personal stories and experiences of combat have been silenced by society at large and also, to varying degrees, within their own families, the Church, and among the younger generation who have grown up under a different dispensation. The conflict between vacillating narratives of villains who fought on the wrong side of history and victims of a closed socialisation system has supported the identity struggle faced by many veterans today. Against this backstory, this article explores the effects of storytelling as a trauma release using a narrative approach.Contribution: This article offers a contribution to the use of storytelling in pastoral conversations as a trauma release for untold stories. This insight links to the focus and scope of the journal as a pastoral narrative approach has been used under the umbrella of Practical Theology. (shrink)

The purpose of this study was to map the distribution of publications on plagiarism among higher educational institutions in sub-Saharan Africa (SSA). Studies reviewed were based on 171 plagiarism related publications within a decade (2012–2022). Findings revealed that most plagiarism related articles were published in 2016. Additionally, a majority of the studies (53) were from Nigeria and Ghana (23). Most of the articles focused on students’ and faculty’s awareness of plagiarism, and institutional prevention of plagiarism, but were rather marginal on (...) challenges involved in preventing plagiarism, as well as effects of plagiarism. Dominant forms of plagiarism were self-plagiarism, branded plagiarism and commission plagiarism. However, major causes of plagiarism comprised easy access to digital information and resources; poor supervision of students; pressure on academics to publish for promotion; and insufficient skills development regarding ethical academic writing. Additionally, plagiarism preventive software and policies on plagiarism were the main ways of preventing plagiarism. Finally, in fighting plagiarism, higher educational institutions in SSA encountered challenges such as lack of well-trained academic experts to detect and report plagiarism cases; reluctance on the part of technical administrative staff to investigate works for traces of plagiarism; and low plagiarism detection skills from project supervisors. Based on the findings, recommendations are made to stakeholders for future research, policy and practice. (shrink)

The conceptual structure of orthodox quantum mechanics has not provided a fully satisfactory and coherent description of natural phenomena. With particular attention to the measurement problem, we review and investigate two unorthodox formulations. First, there is the model advanced by GRWP, a stochastic modification of the standard Schrödinger dynamics admitting statevector reduction as a real physical process. Second, there is the ontological interpretation of Bohm, a causal reformulation of the usual theory admitting no collapse of the statevector. Within these two (...) seemingly quite different approaches, we discuss in a comparative manner, several points: The meaning of the state vector, the status of quantum probability, the legitimacy of attributing macro objective properties to physical systems, and the possibility of retrieving the classical limit. Finally, we consider aspects of non-locality and relevant difficulties with formulating a relativistic generalization of the two approaches. (shrink)

An outstanding problem in so-called modal interpretations of quantum mechanics has been the specification of a dynamics for the properties introduced in such interpretations. We develop a general framework (in the context of the theory of stochastic processes) for specifying a dynamics for interpretations in this class, focusing on the modal interpretation by Vermaas and Dieks. This framework admits many empirically equivalent dynamics. We give some examples, and discuss some of the properties of one of them. This approach is applicable (...) to a wider class of theories, in particular, those using (discrete) strict effective—as in decoherence theory—superselection rules. (shrink)

This book examines in detail two of the fundamental questions raised by quantum mechanics. First, is the world indeterministic? Second, are there connections between spatially separated objects? In the first part, the author examines several interpretations, focusing on how each proposes to solve the measurement problem and on how each treats probability. In the second part, the relationship between probability (specifically determinism and indeterminism) and non-locality is examined, and it is argued that there is a non-trivial relationship between probability and (...) non-locality. The author then re-examines some of the interpretations of part one of the book in the light of this argument, and considers how they fare with regard to locality and Lorentz invariance. The book will appeal to anyone with an interest in the interpretation of quantum mechanics, including researchers in the philosophy of physics and theoretical physics, as well as graduate students in those fields.

Economist Frank Knight drew a distinction between decisions under risk and decisions under uncertainty. Despite the significance of this distinction for decision theory, we argue that there has been inadequate attention to the difficulties involved in classifying decision situations into these categories. Using the risk assessment of carbon nanotubes as an example, we show that it is often unclear whether there is adequate information to classify a decision situation as being under risk as opposed to uncertainty. We conclude by providing (...) two suggestions for responding to these difficulties: treating decisions as real-world experiments; and promoting broadly based deliberation about quantitative information.

Realist synthesis is often offered as a useful strategy to understand intervention complexity. Its unique selling point is its basis in a critical realist philosophy of science. However, we argue t...

This essay is a discussion of the philosophical and foundational issues that arise in non-relativistic quantum theory. After introducing the formalism of the theory, I consider: characterizations of the quantum formalism, empirical content, uncertainty, the measurement problem, and non-locality. In each case, the main point is to give the reader some introductory understanding of some of the major issues and recent ideas.

We consider an extension of signaling games to the case of prediction, where one agent perceives the current state of the world and sends a signal. The second agent perceives this signal, and makes a prediction about the next state of the world. We suggest that such games may be the basis of a model for the evolution of successful theorizing about the world.

The neural cell adhesion molecule (N‐CAM) is believed to be a key regulator of adhesive events in the nervous system and skeletal muscle. The recent isolation of N‐CAM cDNAs from different tissues has identified a high degree of diversity in primary amino acid sequence between different isoforms. In this article, we review these recent studies and discuss methods for unravelling the functional consequences of the generation of multiple N‐CAM polypeptides using gene transfection approaches.

The improvement of the welfare of inhabitants of arid and semi-arid lands, either through the enhancement of existing livelihoods or the promotion of alternative ones, and their potential constraints are discussed. Alternative livelihoods are discussed under regenerative and extractive themes with respect to environmental stability. Regenerative (i.e., non-extractive) livelihoods include activities like apiculture, poultry keeping, pisciculture, silkworm production, drought tolerant cash cropping, horticulture, community wildlife tourism, processing of livestock and crop products, agro-forestry for tree products, and micro-enterprises in the informal (...) sector. Examples of livelihoods that are extractive or potentially so include timber production, woodcarving, basketry, brick making, sand scooping, and charcoal making. Suggestions to improve these livelihoods in a sustainable manner are offered. (shrink)

Quantum mechanics has sometimes been taken to be an empiricist (vs. realist) theory. I state the empiricist's argument, then outline a recently noticed type of measurement--protective measurement--that affords a good reply for the realist. This paper is a reply to scientific empiricism (about quantum mechanics), but is neither a refutation of that position, nor an argument in favor of scientific realism. Rather, my aim is to place realism and empiricism on an even score in regards to quantum theory.

In this article I examine the view, common amongst several contemporary legal positivists, that rules of recognition are to be understood as conventional rules of some kind. The article opens with a discussion of H.L.A. Hart's original account of the rule of recognition in the 1st edn of The Concept of Law and argues that Hart did not view the rule of recognition as a conventional rule in that account. I then discuss Hart's apparent turn towards a conventionalist understanding of (...) the rule of recognition in the ‘Postscript’ to the 2nd edn of The Concept of Law, and attempt to cast doubt on the strength of Hart's commitment to such a turn, and on the reasons prompting him to make it. Finally, I consider one of the most interesting contemporary conventionalist accounts of rules of recognition, namely Andrei Marmor's view that such rules should be understood as the constitutive conventions of partly autonomous social practices. My aim in this part of the article is to compare Marmor's account with my earlier interpretation of Hart's views, and to consider whether Marmor's account truly is conventionalist in character and whether it provides us with a persuasive conventionalist understanding of rules of recognition.

There is evidence that asexual reproduction has a long-term disadvantage when compared to sexual reproduction. This disadvantage is usually assumed to arise from the more efficient incorporation of advantageous mutations by sexual populations. We consider here the effect on asexual and sexual populations of changes in the fitness of harmful mutations. It is shown that the re-establishment of equilibrium following environmental change is generally faster in sexual populations, and that the mutational load experienced by the sexual population can be significantly (...) less during this period than that experienced by an asexual one. Changes in the fitness of harmful mutations may therefore impose a greater long-term disadvantage on asexual populations than those which are sexual. (shrink)

I review the modal interpretation of quantum mechanics, some versions of which rely on the biorthonormal decomposition of a statevector to determine which properties are physically possessed. Some have suggested that these versions fail in the case of inaccurate measurements, i.e., when one takes tails of the wavefunction into account. I show that these versions of the modal interpretation are satisfactory in such cases. I further suggest that a more general result is possible, namely, that these versions of the modal (...) interpretation never encounter the sort of trouble that has been claimed to arise in the case of inaccurate measurement.
