Microlearning-based lessons are still new in the field of education because it primarily focuses on corporate training and adult learning. Hence, limited research was conducted in basic education even in higher education. Microlearning-based lessons are designed and delivered in the form of small, bite-sized information which allows students to achieve a certain learning objective. The main purpose of this research is to determine the effectiveness of Microlearning-based Lessons in Chemistry in the level of academic performance of 18 Grade 9 students (...) under the online learning modality. Moreover, the research instrument used was a researcher-made pretest-posttest based on the learning competencies of the Most Essential Learning Competency (MELC) consisting of 25 multiple choice items along the topics in Grade 9 Chemistry during the Second Quarter of the school year 2020-2021. Mean and paired t-tests were used as tools for analysis. Findings reveal that students’ exposure to Microlearning-based Lessons in Teaching Grade 9 Chemistry improved their level of academic performance in Chemistry. This implies that students perform better when they use microlearning-based lessons in learning Chemistry. Thus, it can be concluded that the level of performance in Chemistry of Grade 9 students greatly improved after exposure to microlearning-based lessons. Furthermore, this shows the effectiveness of the intervention material in improving their level of academic performance, thus the microlearning-based lessons be adopted in teaching Chemistry is recommended.

This study investigated the prevalence, perceived risk factors and effects of enuresis among school-age children in Nsukka local government area. The study adopted a descriptive cross-sectional survey research design with a population of 7,794 Junior Secondary Students within the age range of 9-12years in the study area. Multi-stage sampling technique was employed to select a sample of 820 students from 10 selected schools. A structured questionnaire was the instrument for data collection. The reliability of the questionnaire was 0.86 Cronbach’s alpha (...) showing a good internal consistency of the test items. Data were analysed using frequencies, percentages means and standard deviations. Findings showed that prevalence of bedwetting among the respondents was 17.8%, 14.6% among males and 24.4% among females. The prevalence of primary bedwetting was 12.7%, 5.0% experienced secondary bedwetting, 15.0% experienced nocturnal enuresis and 2.6% experienced diurnal bedwetting. Dreaming of urinating, drinking a lot of fluid before bed and cold weather were some of the risk factors of bedwetting identified by the respondents. Some of the effects of bedwetting identified by the respondents were that bedwetting children often smell bad and bedwetting makes children feel sad. Preventive, curative, hygiene management and reinforcement strategies for enuresis were identified by the respondents. It was concluded that bedwetting negatively affects children in such ways as making them have an offensive smell, sad feelings, mockery and loss of respect from friends. School authorities should therefore make out time within the school year, to create awareness and teach school children about enuresis to reduce the stigma and embarrassment they face. (shrink)

I explore the possibility that the feminine, like art, can be thought in terms of Jean-Luc Nancy’s concept of the singular plural. In Les Muses, Nancy claims that art provides for the rethinking of a technë not ruled by instrumentality. Specifically, in rethinking aesthetics in terms of the debates laid out by Kant, Hegel and Heidegger, he resituates the ontological in terms of the specificity of the techniques of each particular artwork; each artwork establishes relations particular to its world or (...) worlds. What is at stake in the singular plural is the multiplicity of relations that are lost in the unifying gestures that arise out of radical oppositions. I rethink the singular plural through a phenomenological encounter with Barb Hunt’s artwork, Antipersonnel, a collection of hand-knitted replicas of antipersonnel landmines. (shrink)

Amongst the anonymous critics of Locke's "Essay concerning Human Understanding" was a writer of very considerable contemporary eminence, Thomas Burnet. Burnet's criticism is contained in "Remarks upon an Essay Concerning Humane Understanding" and in two subsequent sets of Remarks. This monograph surveys the clash between Locke and Burnet on morality, certainty in revealed religion, and the immortality of the soul.

When looking at a scene, observers feel that they see its entire structure in great detail and can immediately notice any changes in it. However, when brief blank fields are placed between alternating displays of an original and a modified scene, a striking failure of perception is induced: identification of changes becomes extremely difficult, even when changes are large and made repeatedly. Identification is much faster when a verbal cue is provided, showing that poor visibility is not the cause of (...) this difficulty. Identification is also faster for objects mentioned in brief verbal descriptions of the scene. These results support the idea that observers never form a complete, detailed representation of their surroundings. In addition, results also indicate that attention is required to perceive change, and that in the absence of localized motion signals it is guided on the basis of high-level interest. (shrink)

Many epistemologists are enamored with a defeat condition on knowledge. In this paper we present some implementation problems for defeatism, understood along either internalist or externalist lines. We then propose that one who accepts a knowledge norm of belief, according to which one ought to believe only what one knows, can explain away much of the motivation for defeatism. This is an important result, because on the one hand it respects the plausibility of the intuitions about defeat shared by many (...) in epistemology; but on the other hand, it obviates the need to provide a unified account of defeat which plays well with the most plausible views of how knowledge fits with evidential probability.

Artificial intelligence (AI) is an area of computer science that emphasizes the creation of intelligent machines or software that work and react like humans. Some of the activities computers with artificial intelligence are designed for include, Speech, recognition, Learning, Planning and Problem solving. Deep learning is a collection of algorithms used in machine learning, It is part of a broad family of methods used for machine learning that are based on learning representations of data. Deep learning is a technique used (...) to produce Pneumonia detection and classification models using x-ray imaging for rapid and easy detection and identification of pneumonia. In this thesis, we review ways and mechanisms to use deep learning techniques to produce a model for Pneumonia detection. The goal is find a good and effective way to detect pneumonia based on X-rays to help the chest doctor in decision-making easily and accuracy and speed. The model will be designed and implemented, including both Dataset of image and Pneumonia detection through the use of Deep learning algorithms based on neural networks. The test and evaluation will be applied to a range of chest x-ray images and the results will be presented in detail and discussed. This thesis uses deep learning to detect pneumonia and its classification. (shrink)

Large changes in a scene often become difficult to notice if made during an eye movement, image flicker, movie cut, or other such disturbance. It is argued here that this _change blindness_ can serve as a useful tool to explore various aspects of vision. This argument centers around the proposal that focused attention is needed for the explicit perception of change. Given this, the study of change perception can provide a useful way to determine the nature of visual attention, and (...) to cast new light on the way that it is?and is not?involved in visual perception. To illustrate the power of this approach, this paper surveys its use in exploring three different aspects of vision. The first concerns the general nature of _seeing_. To explain why change blindness can be easily induced in experiments but apparently not in everyday life, it is proposed that perception involves a _virtual representation_, where object representations do not accumulate, but are formed as needed. An architecture containing both attentional and nonattentional streams is proposed as a way to implement this scheme. The second aspect concerns the ability of observers to detect change even when they have no visual experience of it. This _sensing_ is found to take on at least two forms: detection without visual experience (but still with conscious awareness), and detection without any awareness at all. It is proposed that these are both due to the operation of a nonattentional visual stream. The final aspect considered is the nature of visual attention itself?the mechanisms involved when _scrutinizing_ items. Experiments using controlled stimuli show the existence of various limits on visual search for change. It is shown that these limits provide a powerful means to map out the attentional mechanisms involved. (shrink)

We address a long-standing debate over whether classical magnetic forces can do work, ultimately answering the question in the affirmative. In detail, we couple a classical particle with intrinsic spin and elementary dipole moments to the electromagnetic field, derive the appropriate generalization of the Lorentz force law, show that the particle's dipole moments must be collinear with its spin axis, and argue that the magnetic field does mechanical work on the particle's elementary magnetic dipole moment. As consistency checks, we calculate (...) the overall system's energy-momentum and angular momentum, and show that their local conservation equations lead to the same force law and therefore the same conclusions about magnetic forces and work. We also compute the system's Belinfante-Rosenfeld energy-momentum tensor. (shrink)

This paper is an examination of the concept of recognition and its connection with identity and respect. This is related to the question of how women are or are not adequately recognised or respected for their achievements in sport and whether eliminating sex segregation in sport is a solution. This will require an analysis of the concept of excellence in sport, as well as the relationship between fairness and inclusion in an activity that is fundamentally about bodily movement. I argue (...) that attempts to address the problem of women’s recognition in sport need to do so in ways that neither eliminate sport as a fairness regulated system for developing individual excellence in bodily movement nor that prevent women’s achievement of sporting excellence, with the regard that belongs to them. Doing this requires us to decide whether sport is about champions or about individual excellence. (shrink)

Assertion is governed by an epistemic norm requiring knowledge. This idea has been hotly debated in recent years, garnering attention in epistemology, philosophy of language, and linguistics. This chapter presents and extends the main arguments in favor of the knowledge norm, from faulty conjunctions, several conversational patterns, judgments of permission, excuse, and blame, and from showing how. (Paired with a chapter by Peter J. Graham and Nikolaj J. L. L. Pedersen, "Knowledge is Not Our Norm of Assertion.").

I demonstrate that a "speech act" theory of meaning for imperatives is—contra a dominant position in philosophy and linguistics—theoretically desirable. A speech act-theoretic account of the meaning of an imperative !φ is characterized, broadly, by the following claims. -/- LINGUISTIC MEANING AS USE !φ’s meaning is a matter of the speech act an utterance of it conventionally functions to express—what a speaker conventionally uses it to do (its conventional discourse function, CDF). -/- IMPERATIVE USE AS PRACTICAL !φ's CDF is to (...) express a practical (non-representational) state of mind—one concerning an agent's preferences and plans, rather than her beliefs. -/- Opposed to speech act accounts is a preponderance of views which deny that a sentence's linguistic meaning is a matter of what speech act it is used to perform, or its CDF. On such accounts, meaning is, instead, a matter of "static" properties of the sentence—e.g., how it depicts the world as being (or, more neutrally, the properties of a model-theoretic object with which the semantic value of the sentence co-varies). On one version of a static account, an imperative 'shut the window!' might, for instance, depict the world as being such that the window must be shut. -/- Static accounts are traditionally motivated against speech act-theoretic accounts by appeal to supposedly irremediable explanatory deficiencies in the latter. Whatever a static account loses in saying (prima facie counterintuitively) that an imperative conventionally represents, or expresses a picture of the world, is said to be offset by its ability to explain a variety of phenomena for which speech act-theoretic accounts are said to lack good explanations (even, in many cases, the bare ability to offer something that might meet basic criteria on what a good explanation should be like). -/- I aim to turn the tables on static accounts. I do this by showing that speech act accounts are capable of giving explanations of phenomena which fans of static accounts have alleged them unable to give. Indeed, for a variety of absolutely fundamental phenomena having to do with the conventional meaning of imperatives (and other types of practical language), speech act accounts provide natural and theoretically satisfying explanations, where a representational account provides none.

One of the most plausible and widely discussed examples of strong emergence is molecular structure. The only detailed account of it, which has been very influential, is due to Robin Hendry and is formulated in terms of downward causation. This paper explains Hendry’s account of the strong emergence of molecular structure and argues that it is coherent only if one assumes a diachronic reflexive notion of downward causation. However, in the context of this notion of downward causation, the strong emergence (...) of molecular structure faces three challenges that have not been met and which have so far remained unnoticed. First, the putative empirical evidence presented for the strong emergence of molecular structure equally undermines supervenience, which is one of the main tenets of strong emergence. Secondly, it is ambiguous how the assumption of determinate nuclear positions is invoked for the support of strong emergence, as the role of this assumption in Hendry’s argument can be interpreted in more than one way. Lastly, there are understandings of causation which render the postulation of a downward causal relation between a molecule’s structure and its quantum mechanical entities, untenable. (shrink)

This chapter covers contemporary work on disagreement, detailing both the conceptual and normative issues in play in the debates in mainstream analytic epistemology, and how these relate to religious diversity and disagreement. §1 examines several sorts of disagreement, and considers several epistemological issues: in particular, what range of attitudes a body of evidence can support, how to understand higher-order evidence, and who counts as an epistemic “peer”. §2 considers how these questions surface when considering disagreements over religion, including debates over (...) the nature of evidence and truth in religion, epistemic humility, concerns about irrelevant influences and about divine hiddenness, and arguments over exclusivism, inclusivism, and pluralism. Finally, §3 summarizes the contributors’ essays in this volume. (shrink)

Newton published his deduction of universal gravity in Principia (first ed., 1687). To establish the universality (the particle-to-particle nature) of gravity, Newton must establish the additivity of mass. I call ‘additivity’ the property a body's quantity of matter has just in case, if gravitational force is proportional to that quantity, the force can be taken to be the sum of forces proportional to each particle's quantity of matter. Newton's argument for additivity is obscure. I analyze and assess manuscript versions of (...) Newton's initial argument within his initial deduction, dating from early 1685. Newton's strategy depends on distinguishing two quantities of matter, which I call ‘active’ and ‘passive’, by how they are measured. These measurement procedures frame conditions on the additivity of each quantity so measured. While Newton has direct evidence for the additivity of passive quantity of matter, he does not for that of the active quantity. Instead, he tries to infer the latter from the former via conceptual analyses of the third law of motion grounded largely on analogies to magnetic attractions. The conditions needed to establish passive additivity frustrate Newton's attempted inference to active additivity. (shrink)

The article offers a reconstruction of John Rawls views on political legitimacy, from A Theory of Justice to his late writings on political liberalism. It argues that Rawls had three conceptions of legitimacy, not two as one might expect based on the distinction between his two major works. Its argument is that the most radical change in Rawls’ thinking about legitimacy occurs in ‘Introduction to the Paperback Edition’ and ‘The Idea of Public Reason Revisited’. Here Rawls assumes that there can (...) be a reasonable pluralism not only of comprehensive doctrines, but also of political liberal conceptions of justice. As a consequence, the standard of political legitimacy is no longer specified as sufficient justice relative to justice as fairness, but instead as sufficient justice relative to a family of political conceptions of justice – a family which in turn is animated by an ideal of public reasoning about constitutional matters and matters of basic justice. The article also shows how Rawls’ late ideal of public reason is grounded in the need for legitimate constitutional government. (shrink)

This paper is a critical discussion of John Dupré's recent defence of promiscuous realism in Part 1 of his The Disorder of Things: Metaphysical Foundations of the Disunity of Science. It also discusses some more general issues in the philosophy of biology and science. Dupré's chief strategy of argumentation appeals to debates within the philosophy of biology, all of which concern the nature of species. While the strategy is well motivated, I argue that Dupré's challenge to essentialist and unificationist views (...) about natural kinds is not successful. One conclusion is that an integrative conception of species is a real alternative to Dupré's pluralism. (shrink)

This article explores a concept of artistic transgression I call aesthetic disobedience that runs parallel to the political concept of civil disobedience. Acts of civil disobedience break some law in order to publicly draw attention to and recommend the reform of a conflict between the commitments of a legal system and some shared commitments of a community. Likewise, acts of aesthetic disobedience break some entrenched artworld norm in order to publicly draw attention to and recommend the reform of a conflict (...) between artworld commitments and some shared commitments of a community. Considering artistic transgressions under the concept of aesthetic disobedience highlights often-overlooked features of modern artworld practices. Most significantly, it draws attention to the deliberative participation of a wide variety of citizens of the artworld, including not just artists and performers but also members of audiences, in the transformation of the rules and boundaries of the artworld itself.

This article makes a case for the capacity of "social practice" accounts of agency and freedom to criticize, resist, and transform systemic forms of power and domination from within the context of religious and political practices and institutions. I first examine criticisms that Michel Foucault's analysis of systemic power results in normative aimlessness, and then I contrast that account with the description of agency and innovative practice that pragmatist philosopher Robert Brandom identifies as "expressive freedom." I argue that Brandom can (...) provide a normative trajectory for Foucault's diagnoses of power and domination, helping to resolve its apparent lack of ethical direction. I demonstrate that Foucault, in turn, presents Brandom with insights that might overcome the charges of abstraction and conservatism that his pragmatic inferentialism frequently encounters. The result is a vindication of social practice as an analytical lens for social criticism that is at once both immanent and radical. (shrink)

This paper is a critique of some ideas about narrow content owing to Horgan and Tienson and Brian Loar.

In two very influential papers from 2008, Tamar Gendler introduced the concept of “alief” to describe the mental state one is in when acting in ways contrary to their consciously professed beliefs. For example, if asked to eat what they know is fudge, but shaped into the form of dog feces, they will hesitate, and behave in a manner that would be consistent with the belief that the fudge is really poop. They alieve that it is disgusting, while they believe (...) it is not. This paper investigates laughter from self-proclaimed egalitarian, tolerant folk, in response to oppressive jokes that might fit the alief-model. If I merely alieve the content of a joke at which I laugh, will that constitute morally exculpating reasons for such laughter? And what else might it imply? This paper will provide insights at the intersections of humor studies, ethics, epistemology, phenomenology, and the philosophy of mind, all while being moderately and appropriately amusing.

A post-Newtonian understanding of matter includes immaterial forces; thus, the concept of ‘physical’ has lost what usefulness it previously had and Cartesian dualism has, consequently, ceased to support a divide between the mental and the physical. A contemporary scientific understanding of mind that goes back at least as far as Priestley in the 18th century, not only includes immaterial components but identifies brain parts in which these components correlate with neural activity. What are we left with? The challenge is no (...) longer to figure out how a physical brain interacts with a nonphysical mind, but to try to unify theories of mind and theories of brain that to date do not share a single property. The challenge is enormous, but at least we can be quite clear about what its nature is, as there is no reason to be distracted by the idea of two distinct substances. In the present volume, many historical perspectives on the mind-body problem are discussed. In what follows, we follow major currents of thought regarding the mind-body problem so that it can be seen how we arrived at the modern conception that it makes sense only to talk about theory unification.

Human vision briefly retains a trace of a stimulus after it disappears. This trace—iconic memory—is often believed to be a surrogate for the original stimulus, a representational structure that can be used as if the original stimulus were still present. To investigate its nature, a flicker-search paradigm was developed that relied upon a full scan (rather than partial report) of its contents. Results show that for visual search it can indeed act as a surrogate, with little cost for alternating between (...) visible and iconic representations. However, the duration over which it can be used depends on the type of task: some tasks can use iconic memory for at least 240 ms, others for only about 190 ms, while others for no more than about 120 ms. The existence of these different limits suggests that iconic memory may have multiple layers, each corresponding to a particular level of the visual hierarchy. In this view, the inability to use a layer of iconic memory may reflect an inability to maintain feedback connections to the corresponding representation. (shrink)

A heuristic is a rule of thumb. In psychology, heuristics are relatively simple rules for making judgments. A fast heuristic is easy to use and allows one to make judgments quickly. A frugal heuristic relies on a small fraction of the available evidence in making judgments. Typically, fast and frugal heuristics (FFHs) have, or are claimed to have, a further property: They are very reliable, yielding judgments that are about as accurate in the long run as ideal non-fast, non-frugal rules. (...) This paper introduces some well-known examples of FFHs, raises some objections to the FFH program, and looks at the implications of those parts of the FFH program about which we can have some reasonable degree of confidence.

When hospitals face surges of patients with COVID-19, fair allocation of scarce medical resources remains a challenge. Scarcity has at times encompassed not only hospital and intensive care unit beds—often reflecting staffing shortages—but also therapies and intensive treatments.

Should their decision to forgo vaccination be considered when allocating scarce resources? Some have suggested it should, while others disagree. We offer a (...) framework for evaluating when it is ethical and briefly discuss its legality in American law. (shrink)

Doctors must now take a fifth vital sign from their patients: pain reports. I use this as a case study to discuss how different schools of psychology (introspectionism, behaviorism, cognitive psychology) have treated verbal reports about the contents of consciousness. After examining these differences, I suggest that, with new methods of mapping data about neurobiological states with behavioral data and with verbal reports about conscious experience, we should reconsider some of the introspectionists' goals and methods. I discuss examples from cognitive (...) psychology, including pain researchers' attempts to develop self-reports of pain so that they can be, like other vital signs, reliable indicators of internal states.

There appears to be a tension between two commitments in liberalism. The first is that citizens, as rational agents possessing dignity, are owed a justification for principles of justice. The second is that members of society who do not meet the requirements of rational agency are owed justice. These notions conflict because the first commitment is often expressed through the device of the social contract, which seems to confine the scope of justice to rational agents. So, contractarianism seems to ignore (...) the justice claims of the severely cognitively impaired. To solve this problem, Martha Nussbaum proposes the capabilities approach. The justifiability condition, on this approach, is met by the idea of overlapping consensus. This essay argues that overlapping consensus cannot meet liberalism’s justifiability condition, nor is it more inclusive of the cognitively impaired. Therefore, we have reason to retain the contract device and look for another way to ensure that liberalism respects the justice claims of all. (shrink)

Considerable variation exists not only in the kinds of transposable elements (TEs) occurring within the genomes of different species, but also in their abundance and distribution. Noting a similarity to the assortment of organisms among ecosystems, some researchers have called for an ecological approach to the study of transposon dynamics. However, there are several ways to adopt such an approach, and it is sometimes unclear what an ecological perspective will add to the existing co-evolutionary framework for explaining transposon-host interactions. This (...) review aims to clarify the conceptual foundations of transposon ecology in order to evaluate its explanatory prospects. We begin by identifying three unanswered questions regarding the abundance and distribution of TEs that potentially call for an ecological explanation. We then offer an operational distinction between evolutionary and ecological approaches to these questions. By determining the amount of variance in transposon abundance and distribution that is explained by ecological and evolutionary factors, respectively, it is possible empirically to assess the prospects for each of these explanatory frameworks. To illustrate how this methodology applies to a concrete example, we analyzed whole-genome data for one set of distantly related mammals and another more closely related group of arthropods. Our expectation was that ecological factors are most informative for explaining differences among individual TE lineages, rather than TE families, and for explaining their distribution among closely related as opposed to distantly related host genomes. We found that, in these data sets, ecological factors do in fact explain most of the variation in TE abundance and distribution among TE lineages across less distantly related host organisms. Evolutionary factors were not significant at these levels. However, the explanatory roles of evolution and ecology become inverted at the level of TE families or among more distantly related genomes. Not only does this example demonstrate the utility of our distinction between ecological and evolutionary perspectives, it further suggests an appropriate explanatory domain for the burgeoning discipline of transposon ecology. The fact that ecological processes appear to be impacting TE lineages over relatively short time scales further raises the possibility that transposons might serve as useful model systems for testing more general hypotheses in ecology.

Verbal irony constitutes a rough class of indirect intentional communication involving a complex interaction of language-specific and communication-general phenomena. Conversationalists use verbal irony in conjunction with paralinguistic signals such as speech prosody. Researchers examining acoustic features of speech communication usually focus on how prosodic information relates to the surface structure of utterances, and often ignore prosodic phenomena associated with implied meaning. In the case of verbal irony, there exists some debate concerning how these prosodic features manifest themselves in conversation. A (...) form-function approach can provide a valuable tool for understanding speakers' varied vocal strategies in this domain. Here I describe several ways conversationalists employ prosodic contrasts, laughter, and other speech characteristics in their attempts to communicate effectively and efficiently. The presented examples, culled from spontaneous conversation recordings, reveal just a small sample of the enormous variation in delivery styles speakers adopt when communicating with ironic language.

David Lewis objected to theories that posit necessary connections between distinct entities and to theories that involve a magical grasping of their primitives. In On the Plurality of Worlds, Lewis objected to nondescript ersatzism on these grounds. The literature contains several reconstructions of Lewis’ critique of nondescript ersatzism but none of these interpretations adequately address his main argument because they fail to see that Lewis’ critique is based on broader methodological considerations. I argue that a closer look at his methodology (...) reveals the broader objection he presented against nondescript ersatzism. This objection, I further argue, remains a challenge for the ersatzer who posits structure-less entities as possible worlds. (shrink)

A reading of Feyerabend in Against Method, and a comparison of C.S. Peirce.

The study determined the influence of innate mathematical characteristics on the number sense competencies of junior high school students in a Philippine public school. The descriptive-correlational research design was used to accomplish the study involving a nonrandom sample of sixty 7th-grade students attending synchronous math sessions. Data obtained from the math-specific Learning Style and Self-Efficacy questionnaires and the modified Number Sense Test (NST) were analyzed and interpreted using descriptive statistics, Pearson’s Chi-Square, and Simple Linear Regression analysis. The research instruments and (...) statistics were all validated and tested for reliability. The analysis revealed that the students are visual learners, had no or slight self-efficacy, and their number sense competency level is poor. They encountered difficulty in all the components and domains of the NST. Moreover, the students’ mathematical self-efficacy is significantly related and may influence their number sense competency level. Building upon the learners’ self-efficacy to further their understanding and skills in number sense is necessary. (shrink)

A plausible explanation of the wrongfulness of threatening, advanced most explicitly by Mitchell Berman, is that the wrongfulness of threatening derives from the wrongfulness of the act threatened. This essay argues that this explanation is inadequate. We can learn something important about the wrongfulness of threatening (with implications for thinking about coercion) by comparing credible threats to some other claims of impending harm. A credible bluff threat to do harm is likely to be more and differently wrongful than making intentionally (...) false warnings about other sources of harm. This essay surveys some examples to secure this point, shows that Berman's moralized account of their wrongfulness is wanting, and offers the outline of an approach better suited to explain the wrongfulness of threatening.1.

Content disjunctivism is the view that veridical experience involves contents and objects that differ from those of corresponding hallucinations. On one formulation of this view, we are aware of ordinary material things in our surroundings when we experience veridically, and we are aware of mere appearances when we hallucinate. This paper proposes a way of developing this view and offers some considerations in support. Central to the proposed regimentation will be a distinction between different notions of appearance. We distinguish between (...) the notion of something merely appearing to have a property and the notion of mere appearances, which are types of objects that we can refer to and be aware of. Mere appearances are not sense data or Meinongian non-existent objects but existing objects that do not have the properties that they appear to have. These notions of appearance will be elucidated, in particular by characterizing how they are involved in hallucination and illusion. I argue that the resulting view is supported by how our mental life seems to us when we experience our environment. (shrink)

In a recent very interesting and important challenge to tracking theories of knowledge, Williams & Sinhababu claim to have devised a counter-example to tracking theories of knowledge of a sort that escapes the defense of those theories by Adams & Clarke.

Luck egalitarianism has been criticized for condoning some cases of oppression and condemning others for the wrong reason—namely, that the victims were not responsible for their oppression. Oppression is unjust, however, the criticism says, regardless of whether victims are responsible for it, simply because it is contrary to the equal moral standing of persons. I argue that four luck egalitarian responses to this critique are inadequate. Two address only the first part of the objection and do so in a way (...) that risks making luck egalitarianism inconsistent. A third severely dilutes the luck egalitarian doctrine. A fourth manages to denounce some instances of oppression for the right reason, but at the same time permits other instances of oppression and condemns yet others for the wrong reason. (shrink)

Consequentialist theories determine rightness solely based on real or expected consequences. Although such theories are popular, they often have difficulty with generalizing intuitions, which demand concern for questions like “What if everybody did that?” Rule consequentialism attempts to incorporate these intuitions by shifting the locus of evaluation from the consequences of acts to those of rules. However, detailed rule-consequentialist theories seem ad hoc or arbitrary compared to act consequentialist ones. We claim that generalizing can be better incorporated into consequentialism by (...) keeping the locus of evaluation on acts but adjusting the decision theory behind act selection. Specifically, we should adjust which types of dependencies the theory takes to be decision-relevant. Using this strategy, we formulate a new theory, generalized act consequentialism, which we argue is more compelling than rule consequentialism both in modeling the actual reasoning of generalizers and in delivering correct verdicts.

We study the structure of families of theories in the language of arithmetic extended to allow these families to refer to one another and to themselves. If a theory contains schemata expressing its own truth and expressing a specific Turing index for itself, and contains some other mild axioms, then that theory is untrue. We exhibit some families of true self-referential theories that barely avoid this forbidden pattern.

Any realist interpretation of quantum theory must grapple with the measurement problem and the status of state-vector collapse. In a no-collapse approach, measurement is typically modeled as a dynamical process involving decoherence. We describe how the minimal modal interpretation closes a gap in this dynamical description, leading to a complete and consistent resolution to the measurement problem and an effective form of state collapse. Our interpretation also provides insight into the indivisible nature of measurement—the fact that you can't stop a (...) measurement part-way through and uncover the underlying 'ontic' dynamics of the system in question. Having discussed the hidden dynamics of a system's ontic state during measurement, we turn to more general forms of open-system dynamics and explore the extent to which the details of the underlying ontic behavior of a system can be described. We construct a space of ontic trajectories and describe obstructions to defining a probability measure on this space. (shrink)

Initial responses to questionnaires used to assess participants' understanding of informed consent for malaria vaccine trials conducted in the United States and Mali were tallied. Total scores were analyzed by age, sex, literacy (if known), and location. Ninety-two percent (92%) of answers by United States participants and 85% of answers by Malian participants were correct. Questions more likely to be answered incorrectly in Mali related to risk, and to the type of vaccine. For adult participants, independent predictors of higher scores (...) were younger age and female sex in the United States, and male sex in Mali.

Psychopathic individuals display a callous-coldhearted approach to interpersonal and affective situations and engage in impulsive and antisocial behaviors.

Research using a 2-factor or 4-facet model of psychopathy highlights some dimension-specific differences in EF, but this research is limited in scope.

It is a commonsense thesis that unactualized possibilities are not parts of actuality. To keep his modal realism in line with this thesis, David Lewis employed his indexical account of the term “actual.” I argue that the addition of counterpart theory to Lewis’s modal realism undermines his strategy for respecting the commonsense thesis. The case made here also reveals a problem for Lewis’s attempt to avoid haecceitism.

Beauty is evil, a surreptitious diversion of earthly delights planted by the devil, according to the third century theologian-philosopher Tertullian. Beauty is a manifestation of the divine on earth, according to another third century philosopher, Plotinus. Could these two really be talking about the same thing? That beauty evokes an experience of pleasure is probably the only point on which all participants in the continuing debate on beauty agree. But what kinds of pleasure one considers relevant to an experience of (...) beauty, is the crux of the problem of beauty. In ancient, medieval and eighteenth century philosophy, the problem of beauty was framed by the larger concern of what constituted a good life. The question regarding the nature of beauty was answered with a view to its role in achieving the good life for those who cultivated its apprehension. In the twentieth century, philosophers framed the problem of beauty as a problem for conceptual analysis. The questions asked were: Is beauty subjective or objective? Are there properties in the object that count towards beauty in all cases; that are sufficient or necessary for an object to be judged beautiful? What kind of pleasure is the pleasure we experience of beauty? I will examine how these questions can be seen to have been answered by earlier philosophical traditions and then I will use these questions as a guide to developing an explanatory theory of beauty based on contemporary theories of perception.

We present a rigorous way to evaluate the visual perception of correlation in scatterplots, based on classical psychophysical methods originally developed for simple properties such as brightness. Although scatterplots are graphically complex, the quantity they convey is relatively simple. As such, it may be possible to assess the perception of correlation in a similar way. Scatterplots were each of 5.0 extent, containing 100 points with a bivariate normal distribution. Means were 0.5 of the range of the points, and standard deviations (...) 0.2 of this range. Precision was determined via an adaptive algorithm to find the just noticeable differences (jnds) in correlation, i.e., the difference between two side-by-side scatterplots that could be discriminated 75% of the time. Accuracy was measured by direct estimation, using reference scatterplots with fixed upper and lower values, with a test scatterplot adjusted so that its correlation appeared to be halfway between these. This process was recursively applied to yield several further estimates. Results of the discrimination tests show jnd(r) = k (1/b – r), where r is the Pearson correlation, and parameters 0 < k, b < 1. Integration yields a subjective estimate of correlation g(r) = ln(1 – br) / ln(1– b). The values of b found via discrimination closely match those found via direct estimation. As such, it appears that the perception of correlation in a scatterplot is completely described by two related performance curves, specified by two easily-measured parameters. (shrink)

People can laugh at almost anything. What’s the deal with that? What makes something funny? -/- This essay reviews some theories of what it is for something to be funny. Each theory offers insights into this question, but no single approach provides a comprehensive answer.

This paper poses a problem of promiscuity for views that endorse material constitution as a metaphysic relation.

This paper refines a number of theoretical distinctions relevant to deceptive play, in particular the difference between merely misleading actions and types of simulation commonly considered beyond the pale, such as diving. To do so, I rely on work in the philosophy of language about conversational convention and implicature, the distinction between lying and misleading, and their relation to concepts of seduction and bullshit. The paper works through a number of possible solutions to the question of what is wrong with (...) simulation and its difference from strategic fouling, including the argument that games and their rules operate like contracts. I conclude that the wrongness lies in the injustice of unfair advantage gained through actions that silence opposition by resort to unanswerable play. (shrink)

The sphere of international tourism for the period 2000–2018 has been explored and analyzed in the article. The dynamics of the world tourist flows development and income from international tourism are considered, the determinants of development are derived, the regional structure of the world market of tourist services is given. The development of the tourism industry in the world is analyzed by indicators: the number of tourist arrivals, tourism revenues at current prices, total contribution of tourism to GDP. The main (...) tourist regions are analyzed in the context of the study, they are compared both in terms of the number of tourist visits, and a list of the TOP 10 countries by volume of foreign exchange earnings from tourism in recent years. It is concluded that in recent years, there is a continuing upward trend in demand for emerging markets, with old markets such as the European market, partially losing its popularity. In the process of research, it is determined that in the conditions of development of the world economy, expansion of volumes of international trade, improvement of means of transport, communication, increase of internationalization and globalization of the world economy the demand for tourist services increases. One of the peculiarities of the development of the international tourist services market is the globalization of the market, which has reached all sectors of the tourism industry. It is concluded that nowadays international tourism is an important area of international economic activity, a complex sphere that significantly affects both the structure and the situation in the world economy as well as the economies of most individual countries and regions of the world. Tourism development has a stimulating effect on such sectors of the economy as transport, communications, trade, construction, agriculture, production of consumer goods, and іt is one of the most promising areas of structural restructuring of the economy, confirming the amount of foreign exchange earnings from tourism in the world in general and in individual countries. It is the increasing demand for tourism services and the volume of foreign exchange earnings from tourism in the world makes the topic relevant for further research. (shrink)
