This paper is concerned with the formulation and analysis of an epidemic model of COVID-19 governed by an eight-dimensional system of ordinary differential equations, by taking into account the first dose and the second dose of vaccinated individuals in the population. The developed model is analyzed and the threshold quantity known as the control reproduction number R0\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\mathcal {R}_{0}$$\end{document} is obtained. We investigate the equilibrium stability of the system, and the COVID-free equilibrium (...) is said to be locally asymptotically stable when the control reproduction number is less than unity, and unstable otherwise. Using the least-squares method, the model is calibrated based on the cumulative number of COVID-19 reported cases and available information about the mass vaccine administration in Malaysia between the 24th of February 2021 and February 2022. Following the model fitting and estimation of the parameter values, a global sensitivity analysis was performed by using the Partial Rank Correlation Coefficient (PRCC) to determine the most influential parameters on the threshold quantities. The result shows that the effective transmission rate (α)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$(\alpha )$$\end{document}, the rate of first vaccine dose (ϕ)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$(\phi )$$\end{document}, the second dose vaccination rate (σ)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$(\sigma )$$\end{document} and the recovery rate due to the second dose of vaccination (η)\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$(\eta )$$\end{document} are the most influential of all the model parameters. We further investigate the impact of these parameters by performing a numerical simulation on the developed COVID-19 model. The result of the study shows that adhering to the preventive measures has a huge impact on reducing the spread of the disease in the population. Particularly, an increase in both the first and second dose vaccination rates reduces the number of infected individuals, thus reducing the disease burden in the population. (shrink)

The goal of this book is to develop a new approach to reading the rule-following sections guided by a simple idea. The simple idea is that Wittgenstein's remarks on rule-following are split between two distinct but complementary projects. The projects are marked not only by different guiding questions, but different presuppositions and methodologies. There is of course precedent for reading the rule-following remarks as comprising two parts. For example, there is the reading of (S. Kripke 1982) on which Wittgenstein first (...) presents a skeptical challenge before turning to its skeptical solution. And there are readings like (Minar 2011) and (Goldfarb 2012) that likewise treat the sections as roughly divided into two components or "chapters." But even these commentators do not explicitly associate their components with different questions and associated methodologies, and so fall short of attributing to Wittgenstein's text anything quite like the thoroughgoing bipartite structure I will be proposing here.

This book offers a systematic examination of the place of religion within Kant's major writings. Kant is often thought to be highly reductionistic with regard to religion - as though religion simply provides the unsophisticated with colourful representations of moral lessons that reason alone could grasp. James DiCenso's rich and innovative discussion shows how Kant's theory of religion in fact emerges directly from his epistemology, ethics and political theory, and how it serves his larger political and ethical projects of (...) restructuring institutions and modifying political attitudes towards greater autonomy. It also illustrates the continuing relevance of Kant's ideas for addressing issues of religion and politics that remain pressing in the contemporary world, such as just laws, transparency in the public sphere and other ethical and political concerns. The book will be valuable for a wide range of readers who are interested in Kant's thought. (shrink)

Two books bound together, from the religious period of one of the most renowned and representative thinkers. Written for laymen, thus easy to understand, it is penetrating and brilliant as well. Illuminations of age-old religious questions from a pragmatic perspective, written in a luminous style.

This article performs a ‘logological’ and ‘spherological’ reading of globalization to critique the topical generality of spatial rhetoric. Posited respectively by Barbara Cassin and Peter Sloterdijk, these seemingly distant theories both show how ‘world’ is created by discourse — that being is an effect of saying. An appropriately equivocal translation of the Greek logos, discourse is here read as the rhetorical forms of ‘inning’ that make space sensible. Cassin's ‘counter-philosophical’ reading of the ancient Greek Sophists challenges post-Parmenidean philosophy's ‘ontopological’ generalization (...) of space into topics, instead attending to the worlds opened by the different ways space is described. This is read alongside Sloterdijk's spherology and its emphasis on transference and ‘inning’, arguing that space is a discursive product, a shared ‘canopy’ under which we make worlds to share meaning. Throughout ‘human’ history, these meanings have, as both Cassin and Sloterdijk argue, determined human life as the ontological being that can be represented under these discursive atmospheres. The article suggests that this can be thought less exclusively by taking up the Sophists’ rhetorics of time and kairos, which reimagines the discursive production of space through contingency and particularity — the sense of reality as the autonomy of the political.

Political leaders engage in alarmism when they inflate threats to the commonweal in order to influence citizens' behavior. A range of democratic theorists argue that alarmism is necessary to maintain political order, with some even contending that alarmism is particularly necessary in democratic polities. Yet there appear to be strong grounds for thinking that alarmism is incompatible with the democratic ethos, namely insofar as it contravenes the principle of collective self-determination. Prima facie, alarmism seems to violate this principle because it (...) involves deception and emotional manipulation, both of which are incompatible with a commitment to autonomous, collective decision-making. However, almost none of the democratic theorists who posit alarmism as a political necessity acknowledge this tension, let alone explore how it might be overcome. In this paper, I rebut the claim that alarmism is essentially anti-democratic and argue that under the right institutional conditions it is broadly compatible with the principle of collective self-determination. I argue that if leaders obtain community consent for their use of alarmism, then the apparent tension with collective autonomy dissolves. In the final section of the paper, I briefly sketch how this consent might feasibly be obtained. (shrink)

David Hume (1711-76) is one of the greatest figures in the history of British philosophy. Of all of Hume's writings, the philosophically most profound is undoubtedly his first, A Treatise on Human Nature. Hume on Morality introduces and assesses: Hume's life and the background of the Treatise ; the ideas and text in the Treatise ; and Hume's continuing importance to philosophy. James Baillie provides us with a map to Books 2 and 3 of the Treatise, focusing on Hume's (...) theory of the passions and morality. This book sets out its principal ideas and arguments of the Treatise in a clear and readable way and is ideal for anyone coming to Hume's work for the first time. (shrink)

Boredom has been characterized as a crisis of meaning, a failure of attention, and a call to action. Yet as a self-regulatory signal writ-large, we are still left with the question of what makes any given boredom episode meaningless, disengaging, or a prompt to act. We propose that boredom is an affective signal that we have deviated from an optimal (‘Goldilocks’) zone of cognitive engagement. Such deviations may be due to a perceived lack of meaning, arise as a consequence of (...) struggles we are experiencing in attending to a task, or be interpreted as a blunt call to find something different to engage with. Thus, the key to understanding boredom lies in its role in keeping us cognitively engaged. -/- . (shrink)

This paper distinguishes two varieties of skepticism and the varieties of philosophical response those skepticisms have engendered. The aim of the exercise is to furnish a perspicuous overview of some of the dialectical relations that obtain across some of the range of problems that philosophers have called (and continue to call) “skeptical”. I argue that such an overview affords a number of forms of philosophical insight.

At first glance, Fichte and Nietzsche might strike us as intellectual contraries. This impression is reinforced by Nietzsche’s disparaging remarks about Fichte. The dearth of critical literature comparing the two thinkers also could easily lead us to believe that they are, for all intents and purposes, irrelevant to one another. In this paper, however, I argue that their theories of subjectivity are in many respects remarkably similar and worthy of comparison. But I further explain how, despite this convergence, their normative (...) philosophies end up so conspicuously at odds with one another. After examining the resemblance between their denials of the substantial self, I respectively analyse Fichte’s and Nietzsche’s positive accounts of subjectivity, self-cultivation, and the political preconditions of self-cultivation. I locate the conceptual juncture at which their practical outlooks begin to part ways in their divergent drive psychologies and in their distinct conceptions of conscience. These apparently minor theoretical differences generate a large-scale disagreement regarding the political systems they believe best enable self-cultivation, with Fichte favouring a democratic regime, while Nietzsche opts for a markedly more aristocratic one. I close by sketching a possible way out of this dilemma. (shrink)

This article criticises David Chalmers’ ‘Reality+’ by interrogating its distinction of virtual reality (VR) from 2D, non-VR video games, a distinction made on the grounds that VR is immersive and these types of video games are not because immersion is a distinct characteristic of 3D perceptually represented VR. Building on the Balcerak Jacksons’ account of ‘representational immersion’, which they acknowledge has ‘perceptual’ and ‘non-perceptual’ elements, I develop an account of ‘non-perceptual representational immersion’ and use it to critique Chalmers’ treatment of (...) VR, immersion, and video games, indirectly problematizing his central ontological claim that ‘virtual reality is genuine reality’ and the reflections he makes about future society which rest upon it. I argue that video games are rich in non-perceptual representational immersion, which includes the representation of non-perceptual information about the structure and behaviour of a virtual world and its systems, the non-perceptual cognitive states that are generated in the player by the virtual world, and the immersion which comes from the constitutively cognitive nature of the player’s engagement with the virtual world, a cognitive engagement construed in an enactive sense. These are just as crucial to the phenomenon of digital immersion as perception. Immersion generally is a much more complicated phenomenon than Chalmers allows for, and it is better conceived as taking place on a spectrum which includes both 3D and 2D experiences of virtual worlds, not as hinging on 3D perceptual representation. I use ‘immersive simulation’ games as a case study. (shrink)

A timely and accessible synthesis of the strengths, weaknesses and reality of science through the eyes of a practicing scientist.

James O. Young seeks to explain why we value music so highly. He draws on the latest psychological research to argue that music is expressive of emotion by resembling human expressive behaviour. The representation of emotion in music gives it the capacity to provide psychological insight--and it is this which explains a good deal of its value.

We construct a notion of teleparallelization for Newton-Cartan theory, and show that the teleparallel equivalent of this theory is Newtonian gravity; furthermore, we show that this result is consistent with teleparallelization in general relativity, and can be obtained by null-reducing the teleparallel equivalent of a five-dimensional gravitational wave solution. This work thus strengthens substantially the connections between four theories: Newton-Cartan theory, Newtonian gravitation theory, general relativity, and teleparallel gravity.

From the acclaimed author and scholar James C. Scott, the compelling tale of Asian peoples who until recently have stemmed the vast tide of state-making to live at arm’s length from any organized state society For two thousand years the disparate groups that now reside in Zomia (a mountainous region the size of Europe that consists of portions of seven Asian countries) have fled the projects of the organized state societies that surround them—slavery, conscription, taxes, corvée labor, epidemics, and (...) warfare. This book, essentially an “anarchist history,” is the first-ever examination of the huge literature on state-making whose author evaluates why people would deliberately and reactively remain stateless. Among the strategies employed by the people of Zomia to remain stateless are physical dispersion in rugged terrain; agricultural practices that enhance mobility; pliable ethnic identities; devotion to prophetic, millenarian leaders; and maintenance of a largely oral culture that allows them to reinvent their histories and genealogies as they move between and around states. In accessible language, James Scott, recognized worldwide as an eminent authority in Southeast Asian, peasant, and agrarian studies, tells the story of the peoples of Zomia and their unlikely odyssey in search of self-determination. He redefines our views on Asian politics, history, demographics, and even our fundamental ideas about what constitutes civilization, and challenges us with a radically different approach to history that presents events from the perspective of stateless peoples and redefines state-making as a form of “internal colonialism.” This new perspective requires a radical reevaluation of the civilizational narratives of the lowland states. Scott’s work on Zomia represents a new way to think of area studies that will be applicable to other runaway, fugitive, and marooned communities, be they Gypsies, Cossacks, tribes fleeing slave raiders, Marsh Arabs, or San-Bushmen.

The past several decades have seen a renaissance in Christian philosophy, led by the work of Alvin Plantinga, Nicholas Wolterstorff, William Alston, Eleonore Stump, and others. In the spirit of Plantinga s famous manifesto, Advice to Christian Philosophers, James K. A. Smith here offers not only advice to Pentecostal philosophers but also some Pentecostal advice to Christian philosophers. In this inaugural Pentecostal Manifestos volume Smith begins from the conviction that implicit in Pentecostal and charismatic spirituality is a tacit worldview (...) or social imaginary. Thinking in Tongues unpacks and articulates the key elements of this Pentecostal worldview and then explores their implications for philosophical reflection on ontology, epistemology, aesthetics, language, science, and philosophy of religion. In each case, Smith demonstrates how the implicit wisdom of Pentecostal spirituality makes unique contributions to current conversations in Christian philosophy. (shrink)

It is intuitive to think that divine transcendence is incompatible with the sacredness of nature, especially when transcendence is combined with the idea that God alone is valuable. Divine transcendence seems to demote this-worldly values in favor of union with God in a disembodied afterlife. Divine transcendence also seems to legitimize hierarchies, including male–female and human-nature hierarchies. Divine immanence seems a better alternative. This set of intuitions about transcendence appears regularly in the field of Religion and Ecology, sometimes as an (...) implicit backdrop rather than an explicit position. This backdrop needs to be thematized and evaluated. For those with ecological concerns, divine transcendence and divine immanence need not be mutually exclusive. Rather, divine transcendence (understood non-contrastively) complements divine immanence and is compatible with both animist and polytheist cosmologies. The extent of this mutual compatibility and its importance for environmental concerns has yet to be fully articulated. (shrink)

In the past few years an increasing number of colleges and universities have added courses in biomedical ethics to their curricula. To some extent, these additions serve to satisfy student demands for "relevance. " But it is also true that such changes reflect a deepening desire on the part of the academic community to deal effectively with a host of problems which must be solved if we are to have a health-care delivery system which is efficient, humane, and just. To (...) a large degree, these problems are the unique result of both rapidly changing moral values and dramatic advances in biomedical technology. The past decade has witnessed sudden and conspicuous controversy over the morality and legality of new practices relating to abortion, therapy for the mentally ill, experimentation using human subjects, forms of genetic interven tion, suicide, and euthanasia. Malpractice suits abound and astronomical fees for malpractice insurance threaten the very possibility of medical and health-care practice. Without the backing of a clear moral consensus, the law is frequently forced into resolving these conflicts only to see the moral issues involved still hotly debated and the validity of existing law further questioned. In the case of abortion, for example, the laws have changed radically, and the widely pub licized recent conviction of Dr. Edelin in Boston has done little to foster a moral consensus or even render the exact status of the law beyond reasonable question.

In lieu of an abstract, here is a brief excerpt of the content:BOOK REVIEWS 525 ever, Scharlemann's work is carefully reasoned, and should serve to encourage further reflection on the manner of human existence that is implied in the relation of discipleship. The book is in general well-printed, but there are some errors. The title of Chapter 4 is given incompletely in the table of contents. On p. 79, read intellectus quaerens fidem for intellectuals quaerens fidem. The Catholic University of (...) America Washington, D.C. JOHN P. GALVIN Time and Eternity. By BRIAN LEFTOW. Ithaca: Cornell University Press, 1991. Pp. xii + 377. $42.95 (cloth). This is a considerable book on a considerable topic-the logical relation of time to eternity, the possibility of a simple God's knowing temporal events, and their presence in God. The book aims to make sense of and defend the claim that God is in fact timeless, and to explore the relations between such a timeless being and temporal beings. The book is thus something of a tour de force which, as Professor Stump herself remarks in a review, no subsequent discussions of the topic will be able to neglect. It is also a mine of information about discussions of this venerable topic, ancient, medieval, and modern, with special emphasis on contemporary controversies. After plainly setting out his working assumptions, Leftow examines the possibility of the timeless and the logic of eternity. He argues that timeless entities do, or at least can, exist, whether or not God exists and is timeless. He argues further that if God exists and is timeless, " coexisting " with time does not make God temporal. Proper discourse of the eternal requires its own peculiar " eternal-present" tense. The author then turns to the classic discussions of these topics in Augustine, Boethius, and Anselm. His treatment of Boethius is mainly based on the contemporary interpretation by Eleanor Stump and Norman Kretzmann-indeed a great deal of the first half of the book consists in fencing with their view. Leftow argues that Stump and Kretzmann are correct in concluding that the Boethian concept of eternity is that of " atemporal duration," though he thinks they arrived at this conclusion for the wrong reasons. Having argued that one can understand Boethian eternity in terms of a form of duration, Leftow goes on to maintain that one can also understand it on the model of an extensionless point. At the same time, he maintains that God's life has earlier and later "positions" in a manner that this reviewer finds reminiscent of the Whiteheadian view 526 BOOK 1mvrnws of the genetic analysis of an actual occasion, or perhaps even of White· head's conception of divine everlastingness. In the long run, however, Leftow finds the Boethian view (at least as interpreted by Stump and Kretzmann) unsatisfactory. The reason is, if I have got it right, that he thinks that for Boethius as well as for Thomas Aquinas and others, God is aware of temporal things inasmuch as they are "present to God" in God's eternity. At the same time Leftow supposes (mistakenly) that for Aquinas God's knowledge is that of an observer, and he goes on to write: "Now if a temporal thing is really present to God, it seems to fallow that God and that thing exist simultaneously" (161, my emphasis). I fail to grasp how that seems to follow, unless one confuses the ontological order with the intentional, hut on the supposition that it does follow, Leftow argues that Boethius can't have it both ways: that God's knowledge, not being simultaneous with temporal events, is not foreknowledge and so does not impede human freedom, yet is truly omniscient, and so simultaneous with temporal events after all. Leftow then turns to the view of Anselm, which he judges more defensible, for he believes he finds in Anselm a position in which the temporal events that God knows are in a real sense thereby in God, and so simultaneous with God's knowledge of them. "On this alternative,... temporal events occur all at once in eternity, in addition to occurring at various points in time.... Temporal events occur at once for God and really do occur at once, in eternity" (219... (shrink)

This work has two major goals. The first is to reframe the problem of political authority from its Conservative framing to a Reformist framing. This change creates a new benchmark for the success of a theory. Rather than justifying a pre-existing intuition, a theory can be successful if it could establish political authority whenever the state itself or an individual’s relationship to it changes. This change also shifts the focus from the state’s right to rule to moral housekeeping. In other (...) words, the main goal is not to see when the state can use coercion against its citizens but rather to determine what political obligations citizens could have under different scenarios so that citizens can more accurately keep track of their moral reasons for action. The second major goal is to call into question epistemic theories of democratic authority through a critical examination of David Estlund’s theory of normative consent. Normative consent cannot establish political authority. Even granting that it could, normative consent would bind individuals to epistemic procedures rather than democratic procedures given that epistemic procedures better solve the moral problems that generate normative consent. However, this then raises worries from the public reason perspective that epistemic procedures would impose a procedure on some citizens which they could reject from a qualified position. To overcome this worry, it is shown that epistemic procedures based on reducing the power of the ignorant rather than raising the power of the experts are not open to such qualified rejection, and democratic procedures in the real world will do no better than a coin flip at selecting correct policies. In the end, one branch of epistemic conceptions of democratic authority are proven untenable. (shrink)

If two people disagree about the beauty of a painting are both judgements valid or can someone be mistaken about the aesthetic value of an artwork? This volume brings together some of the leading philosophers of art and language to debate the status of aesthetic judgements.
