This paper explores ethical debates associated with the UK COVID-19 contact tracing app that occurred in the public news media and broader public policy, and in doing so, takes ethics debate as an object for sociological study. The research question was: how did UK national newspaper news articles and grey literature frame the ethical issues about the app, and how did stakeholders associated with the development and/or governance of the app reflect on this? We examined the predominance of different ethical (...) issues in news articles and grey literature, and triangulated this using stakeholder interview data. Findings illustrate how news articles exceptionalised ethical debate around the app compared to the way they portrayed ethical issues relating to ‘manual’ contact tracing. They also narrowed the debate around specific privacy concerns. This was reflected in the grey literature, and interviewees perceived this to have emerged from a ‘privacy lobby’. We discuss the findings, and argue that this limited public ethics narrative masked broader ethical issues. (shrink)

If we are eventually to understand the capability of higher organisms for perceptual recognition, generalization, recall, and thinking, we must first have answers to three fundamental questions: 1. How is information about the physical world sensed, or detected, by the biological system? 2. In what form is information stored, or remembered? 3. How does information contained in storage, or in memory, influence recognition and behavior? The first of these questions is in the.

The globalization in business and tourism becomes crucial more and more for the economical sustainability of local communities. In the presence of an epidemic outbreak, there must be such a decision on the policy by the host community as whether to accept visitors or not, the number of acceptable visitors, or the condition for acceptable visitors. Making use of an SIRI type of mathematical model, we consider the influence of visitors on the spread of a reinfectious disease in a community, (...) especially assuming that a certain proportion of accepted visitors are immune. The reinfectivity of disease here means that the immunity gained by either vaccination or recovery is imperfect. With the mathematical results obtained by our analysis on the model for such an epidemic dynamics of resident and visitor populations, we find that the acceptance of visitors could have a significant influence on the disease’s endemicity in the community, either suppressive or supportive.

Some first-order theories of divisible ℓ-groups are well known, for example the theory of the totally ordered ones and the theories of the projectable ones , Lattice-ordered Groups, Kluwer Academic Press, Dordrecht, 1989, pp. 41–79). In this paper we study some theories of nonprojectable divisible ℓ-groups, the simplest example of which is . We introduce a generalization of the projectability property . We prove that the class of r-projectable special-valued divisible ℓ-groups is an elementary class and give a classification of (...) its completions. (shrink)

A partir del estudio comparativo de dos obras –el eje del análisis lo constituye el "Iusnaturalismo y Ética Moderna" de Grocio, uno de los cuatro autores explícitamente reconocidos cono fuentes por Vico, de quien Lomonaco escoge la quinta prolusión de apertura de curso en la Universidad de Nápoles– se destacan las interrelaciones que, necesariamente, han de conectar la reflexión filosófica y la práctica juridica, ámbitos entre los cuales median siempre delicadas cuestiones de carácter ético que están, además, inevitablemente impregnadas de (...) historicidad. Se trata, pues, de apuntar algunas ideas acerca del tema "derecho-naturaleza-historia" que, desde la óptica grociana-viquiana, supone incluso una transformación de modelos antropológicos a través del tamiz de un humanismo universalista.From the study of two works –although the core of the analysis is based on Grocio’s "Iusnaturalism and Modern Ethics", an author whom Vico explicitly acknowledges as one of his sources– the interconnections between philosophical reflection and legal practice are emphasized. The aim is to outline some ideas about the problems involved with the wide relationship between "law-nature-history", which from the Grocian-Vichian point of view lead to a deep transformation of anthropological patterns along the lines of the Universalist humanism’s principles.

Errors of judgment regarding pain sensations are not possible. Christopher Hill, in his paper ‘Introspective Awareness of Sensations’, argues that we do sometimes commit ‘errors of judgment’ and he draws on an example that involves the perception of pain to illustrate his point. I analyze Hill’s example and draw on other examples of pain sensations to show how errors of judgment are not possible. I argue that pain sensations appear to be causally shaped and in some cases generated solely by (...) beliefs, expectations and dispositional states. Changes in beliefs, expectations and dispositional states appear to change the sensation that is generated. If pain sensations are generated in the way that I suggest, then the fact that some of the influences that causally shape and generate a pain sensation are constantly subject to change means that there may be little ‘truth’ that can be objectively established regarding a belief about a pain sensation. If there is little ‘truth’ that can be objectively established about a pain sensation, it will be inaccurate to label an instance of pain avowal as an ‘error of judgment’, or to speak about judgments concerning pain in terms of truth or error more generally.

It is very tempting to try to reconcile perception and cognition perceptual symbol systems may be a good way to achieve this; but is there actually a perception-cognition continuum? We offer several arguments for and against the existence of such a continuum and in favor of the choice of perceptual symbol systems. One of these arguments is purely theoretical, some are based on PET-scan observations and others are based on research with handicapped subjects who have communication problems associated with cerebral (...) lesions. These arguments suggest that modal perceptual symbols do indeed exist and that perception and cognition might have a common neuronal basis; but perceptual and cognitive activities require the activation of different neuronal structures.

Background A morally sound framework for benefit-sharing is crucial to minimize research exploitation for research conducted in developing countries. However, in practice, it remains uncertain which stakeholders should be involved in the decision-making process regarding benefit-sharing and what the implications might be. Therefore the study aimed to empirically propose a framework for benefit-sharing negotiations in research by taking HIV vaccine trials as a case. Methods The study was conducted in Tanzania using a case study design and qualitative approaches. Data were (...) collected using in-depth interviews (IDI) and focus group discussions (FGD). A total of 37 study participants were selected purposively comprising institutional review board (IRB) members, researchers, community advisory board (CAB) members, a policymaker, and HIV/AIDS advocates. Deductive and inductive thematic analysis approaches were deployed to analyze collected data with the aid of MAXQDA version 20.4.0 software. Results The findings indicate a triangular relationship between the research community, researched community and intermediaries. However, the relationship ought to take into consideration the timing of negotiations, the level of understanding between parties and the phase of the clinical trial. The proposed framework operationalize partnership interactions in community-based participatory research. Conclusion In the context of this study, the suggested framework incorporates the research community, the community being researched, and intermediary parties. The framework would guarantee well-informed and inclusive decision-making regarding benefit-sharing in HIV vaccine trials and other health-related research conducted in resource-limited settings.

Using a clear, non-technical style, Professor Rohrlich discusses the two major theories of twentieth-century physics: relativity and quantum mechanics. Discussed conceptually and philosophically, rather than using mathematics, the philosophical issues raised show how new discoveries forced physicists to accept often strange and unconventional notions. He aims to remove the mystery and misrepresentation that often surround the ideas of modern physics and to show how modern scientists construct theories, so that the reader can appreciate their successes and failures and understand problems (...) that are as yet unresolved.

A canonical formalism for the relativistic classical mechanics of many particles is proposed. The evolution equations for a charged particle in an electromagnetic field are obtained and the relativistic two-body problem with an invariant interaction is treated. Along the same line a quantum formalism for the spinless relativistic particle is obtained by means of imprimitivity systems according to Mackey theory. A quantum formalism for the spin-1/2 particle is constructed and a new definition of spin1/2 in relativity is proposed. An evolution (...) equation for the spin-1/2 particle in an external electromagnetic field is given. The Bargmann Michel, and Telegdi equation follows from this formalism as a quasiclassical approximation. Finally, a new relativistic model for hydrogenlike atoms is proposed. The spectrum predicted is in agreement with Dirac's when radiative corrections have been added. (shrink)

This paper examines the commonplace assertion that utilitarianism allows for and even, at times, requires the punishment of the innocent. It traces the origins of this doctrine to the writings of the British Idealists and the subsequent development of what is called the post-utilitarian paradigm which posits various justifications for punishment such as retribution, deterrence and reform, finds all of them inadequate, and then, with the addition of other ideas, reconciles them. The idea of deterrence is falsely depicted as the (...) utilitarian contribution to the theory of punishment, while deterrence in fact is one of several elements in the utilitarian theory. The mistake comes from ignoring the pain-pleasure dimension of Benthamite utilitarianism and from regarding the principle of utility itself as the sole criterion of action in a ‘top-down’ fashion.

Towards the close of Book V of theRepublicPlato tells us that the true philosopher has knowledge and that the objects of knowledge are the Forms. By contrast, the ‘lovers of sights and sounds’, he tells us, have no more than belief, the objects of which are physical particulars. He then goes on to present us with some very radical-sounding assertions about the nature of these physical particulars. They are bearers of opposite properties, he says, in so thorough-going a manner that (...) we cannot say of them that they are nor that they are not: they lie somewhere between being and utter non-being.This passage of theRepublic still awaits an agreed interpretation and I want to suggest as a reason for this that it is usually interpreted in isolation. I will argue that it becomes easier to understand when seen against the background of Plato's developing thought. To be more precise, it makes sense when taken as a rejection by Plato of one of his earlier beliefs: namely, a doctrine of essentialism to be found in thePhaedo.The greater part of this paper then will be an attempt to show thatRepublicV is a rejection of thePhaedo'sdoctrine of essences. Its concluding part will try to explain why that doctrine was rejected. (shrink)
