It has been argued by Bernard Linsky and Edward Zalta, and independently by Timothy Williamson, that the best quantified modal logic is one that validates both the Barcan Formula and its converse. This requires that domains be fixed across all possible worlds. All objects exist necessarily; some – those we would usually consider contingent – are concrete at some worlds and non-concrete (but still existent) at others. Linsky and Zalta refer to such objects as ‘contingently non-concrete’. I defend the standard (...) usage of the word ‘exists’, and the view that many objects exist only contingently. I argue that the Linsky/Zalta analysis, and to a lesser extent Williamson’s, suffers not only from a peculiar ontology but also from two related formal difficulties. Their analysis gives either counter-intuitive or ad hoc results about essences, and it fails to accommodate contingently existing abstracta. (shrink)

Sir Arthur Conan doyle wrote fifty-six short stories and four novels about Sherlock Holmes, collectively known as the Canon. The following are all true facts about the Canon: It is true according to the Canon that Sherlock Holmes is a detective. It is true according to the Canon that Queen Victoria hired a private consulting detective, gave him an emerald tiepin, and offered him a knighthood which he refused. The Canon is about Sherlock Holmes. The Canon is about a brilliant (...) private detective who solves many crimes that baffle Scotland yard. The Canon is also about Queen Victoria .This paper argues that the truth of these and similar facts creates some tension for the theory that fictional characters are abstract objects. A proponent of this theory will have to treat sentences and as disanalogous, and to as similarly disanalogous, in a way that undercuts part of the motivation for accepting an ontology of fictional characters.

The standard view of metaphysical necessity is that it is truth in all possible worlds, and therefore that the correct modal logic for metaphysical necessity is S5, in models of which all worlds are accessible from each other. I argue that S5 cannot be the correct logic for metaphysical necessity because accessibility is not symmetric: there are possible worlds that are accessible from ours but from which our world is not accessible. There are (or could be) some individuals who, if (...) they had not existed, could not have existed. Once the possibility of such individuals is lost, it is gone forever. (shrink)

This paper examines the logic of fictions within fictions. I argue that consistently nested consistent fictions must have certain formal characteristics. The most important is that they form a tree structure. Depending on one’s theory of fictional objects, additional constraints may apply regarding the appearance of a fictional object in two or more fictional universes. The background motivation for the paper is to use iterated fiction operators as a tool for making sense of iterated modal operators; I conclude by noting (...) briefly where the results about nested fictions can, and where they cannot, be extended to nested possible worlds.

It has been argued that actualism – the view that there are no non-actual objects – cannot deal adequately with statements involving iterated modality, because such claims require reference, either explicit or surreptitious, to non-actual objects. If so, actualists would have to reject the standard semantics for quantified modal logic (QML). In this paper I develop an account of modality which allows the actualist to make sense of iterated modal claims that are ostensibly about non-actual objects. Every occurrence of a (...) modal operator involves the stipulation of a possible world, and nested modal operators require stipulation of nested possible worlds. I provide an actualistically acceptable (AA) semantics for QML wherein the nesting relation is irreflexive and intransitive and forms a tree. Despite these restrictions, AA models can beshown to be sound and complete for a wide variety of modal logics. (shrink)

It has been alleged that actualism and quantified modal logic are incompatible. My aim in this dissertation is twofold: to defend thoroughgoing actualism with respect to possible objects, and to present a modified semantics for quantified modal logic that is compatible with such a position. The basic strategy is to draw on the parallels between fictions and possible worlds to develop a hierarchical system of worlds-within-worlds ;Actualists usually take first-order modal statements as being about the right objects, by stipulation. Any (...) actualistically acceptable semantics must extend this approach to higher-order modal statements. "I could have had a brother who was a banker but could have been a pianist" means: there is a first-order world in which I have a banker brother, and there exists within that world a second-order world in which that very brother is a pianist. This eliminates the troubling need to identify non-actual objects across worlds of the same order. ;The concept of worlds-within-worlds is analogous to that of consistent fictions-within-fictions. Independent investigations of each concept reveal that both nesting structures are treelike, irreflexive and intransitive. Despite these restrictions, AA models are relatively tractable, being derivable from Kripke models for by unraveling. They are sound and complete for normal propositional modal logics, and for the quantified modal logic Q1R as long as constants are excluded from the language. ;In Chapter 1, I argue for actualism and against some proposed responses to the iterated modality problem. I then present the idea of nested worlds as a solution. Chapter 2 examines the analogous concept of nested fictions, to shed some light on consistent nesting structures. Chapter 3 returns to modality proper; AA models are defined and defended for both propositional and quantified modal logic. Chapter 4 contains the soundness and completeness results, and ends with a somewhat surprising philosophical argument motivated by AA semantics: unless it is metaphysically necessary that all objects have sufficient essences, the correct logic for metaphysical necessity must be weaker than B.

Drawing from research on moral judgment and affective dysfunction, we examined how trait psychopathy and alexithymia, which are characterized as empathic deficits, relate to utilitarian moral judgments in sacrificial dilemmas. As predicted, primary and secondary psychopathy traits and alexithymia were associated with reduced empathic concern. However, primary psychopathy and difficulty identifying feelings (one of three alexithymia traits), but not secondary psychopathy and other two alexithymia traits, were associated with utilitarian judgments. Moreover, hierarchical regression analysis showed that primary psychopathy, difficulty identifying (...) feelings, and empathic concern made unique contributions to the prediction of direct harm on the victim, whereas alexithymia traits made weaker contributions. Although the lack of affective empathy is found in psychopathy and alexithymia, the process through which the two traits lead to utilitarian judgment in sacrificial dilemmas may be distinct. The present findings add to the growing literature, contributing to a fuller picture of the relationship between empathy, trait psychopathy, and alexithymia. (shrink)

Feminism and postcolonialism are allies, and the impressive selection of writings brought together in this volume demonstrate how fruitful that alliance can be. Reina Lewis and Sara Mills have assembled a brilliant selection of thinkers, organizing them into six categories: "Gendering Colonialism and Postcolonialism/Radicalizing Feminism," "Rethinking Whiteness," "Redefining the 'Third World' Subject," "Sexuality and Sexual Rights," "Harem and the Veil," and "Gender and Post/colonial Relations." A bibliography complements the wide-ranging essays. This is the ideal volume for any reader interested (...) in the development of postcoloniality and feminist thought. (shrink)

El perfeccionismo es la exigencia personal, evaluando su propio valor en términos de productividad y logro. Se utiliza una metodología experimental y tiene como objetivo principal conocer si los niños/as de dos cursos de cuarto de primaria son perfeccionistas y proponer actividades utilizando el método REAPSES en la asignatura de Educación física. En conclusión, gracias a las actividades planteadas los alumnos/as afirman encontrarse más relajados y con una idea más clara del significado del estrés y cómo éste les afecta. Sin (...) embargo, en cierto modo, parte del estrés es causado por el nivel de exigencia por parte de las familias. (shrink)

The purpose of this study was to investigate the role of perceived vulnerability to disease, emotions (disgust, anger), and perceived norms in predicting moral judgments of anti-COVID-19-preventive behaviors in US and Japan. A total of 442 Japanese and 365 American participants completed an online survey. Disgust and anger mediated the link between perceived vulnerability to disease (germ aversion) and moral judgments of preventive behaviors across both cultures. Perceived social norms among friends and family were associated with harsh judgments of anti-preventive (...) behaviors for Japanese but not for American participants. Overall, our results suggest that effective strategies for promoting preventive behaviors may be culturally valid if they focus on the fear for infectious disease and related aversive affect. We also discussed the possibility that some strategies could be characteristic of collectivistic cultures, warranting further cross-cultural comparisons. (shrink)

This paper is concerned with the different forms of pleasure and identification activated in the consumption of dominant and subcultural print media. It centres on an analysis of the lesbian visual pleasures generated through the reading of fashion editorial in the new lesbian and gay lifestyle magazines. This consideration of the lesbian gaze is contrasted to the lesbian visual pleasures obtained from an against the grain reading of mainstream women's fashion magazines. The development of the lesbian and gay lifestyle magazines, (...) in the context of the pink pound, produces a situation in which an eroticized lesbian visual pleasure is the overt remit of the magazine, rather than a clandestine pleasure obtained through a transgressive reading of dominant cultural imagery. In contrast to the polysemic free-play of fashion fantasy by which readers produce lesbian pleasure in the consumption of mainstream magazines, responses to the fashion content in the lesbian magazine Diva suggest that in a subcultural context readers deploy a realist mode of reading that demands a monosemic positive images iconography. The article uses the concept of subcultural competency to consider the different ways lesbians read mainstream and subcultural print media and suggests that the conflict over Diva‘s fashion spreads may be linked to changing patterns of identification and the use of dress for recognizability.

ObjectiveTo assess distracted attention and performance on a computer task following completion of a sustained attention and acute media multitasking task among adolescents with varying self-reported usual media multitasking.MethodsNinety-six 13- to 17-year-olds played the video game Tetris following completion of a Go/No-go paradigm to measure sustained attention in the presence of distractors, an acute media multitasking, or a passive viewing condition. Adolescents completed the conditions on separate visits in randomized order. Sustained attention was measured within the Go/No-go task by measuring (...) errors of omission. Distracted attention while playing the Tetris task was measured by computing eye tracking measures of attention to irrelevant distractor images that bordered the Tetris game. Participants also self-reported their daily media multitasking.ResultsThe Go/No-go task revealed important qualitative differences in sustained attention among low and high usual media multitaskers. There was a uniform improvement in sustained attention among low usual media multitaskers, demonstrated by a consistent linear decrease in omission errors. Among high usual media multitaskers, there was initially a decrease in sustained attention followed by an increase. Completing the Go/No-go task also statistically significantly reduced distractibility and increased performance while playing Tetris compared to the passive viewing condition, but only among those with low usual media multitasking. There was a non-statistically significant trend that completing the acute media multitask increased subsequent distractibility and performance while playing Tetris among high media multitaskers.ConclusionIn this sample of adolescents, practicing a sustained attention task reduces distractibility and improves task performance among those who have low levels of usual media multitasking.

En este trabajo se estudia un fenómeno didáctico que puede emerger en la construcción de dos nociones matemáticas, a saber, los números irracionales y la función periódica. Se analizan los conflictos semióticos asociados al reconocimiento visual de la periodicidad numérica y funcional. Se observa que estos conflictos se pueden agrupar fundamentalmente en tres dimensiones: una, cognitiva, relativa a la forma de adquisición de las nociones por los sujetos, en especial en aquellos aspectos relativos a la percepción visual; otra, epistémica, relativa (...) al significado atribuido a los objetos matemáticos; y, finalmente, de enseñanza, relativa a reglas del contrato didáctico. El estudio fundamenta teóricamente y aporta datos empíricos sobre las dificultades asociadas a estas tres dimensiones en la construcción de número irracional y de la función periódica. (shrink)

ABSTRACT:This article examines the place of Machiavelli’sPrincein the history of ethics and the history of leadership philosophy. Close scrutiny indicates that Machiavelli advances an ethical system for leadership that involves uprooting corruption and establishing rule of law. He draws on history and current affairs in order to obtain a realistic understanding of human behavior that forms a basis for a consequentialist ethics. While he claims a good leader might do bad things, this is in situations where necessity constrains a prince (...) to choosing the “least bad” course of action. Furthermore, Machiavelli advocates winning the goodwill of followers through leadership as a source of power. Machiavelli’s leadership ethics has a sophistication not fully enjoyed by his reputation in management scholarship. He would not score as especially “Machiavellian” on the Mach IV. Many of his ideas contain seeds for theories that are now considered important for leadership today. (shrink)

Due to the lockdown caused by the COVID-19 pandemic, e-learning suddenly spread to different levels of education, including university. In Spain, students of sports sciences are prepared during a 4-year study program to work in different areas and with different populations. The aims of this study were to assess the effect of pandemic-driven online teaching on self-efficacy for the inclusion of people with disabilities in a group of university students enrolled in a compulsory course on adapted physical activity ; compare (...) the gains from SE before and after the APA course with a sample of students who followed the same course before the pandemic; and explore the influence on SE scores according to three demographic variables: gender, previous SE training, and previous experience with people with disabilities. The study involved a sample of 124 university students, distributed into two groups: prepandemic and pandemic. They voluntarily completed the Spanish version of the Scale of Self-Efficacy of Physical Education Teachers of Physical Education toward Children with Disabilities, obtaining pre- and postcourse measurements. Due to the sudden lockdown, two-thirds of the pandemic course was taught online, and changes in the teaching strategies and tasks had to be made. Similar gains were obtained in both groups for the three subscales of the SE scale : intellectual, physical, and visual disability. No significant differences were found for comparisons between groups and the interaction effect of the course taught, nor for the three demographic co-variables. This study shows that teaching strategies that encourage student participation and reflections on learning increase student SE, regardless of the teaching format. Moreover, the gains in SE are invariable to demographic co-variables. (shrink)

The widespread critical evidence surrounding executive compensation of listed corporations has boosted shareholder activism in recent decades. The say-on-pay (SOP) mechanism—a vote in which shareholders express their (dis)agreement with executive pay designs—is one of the corporate governance mechanisms that has led to this activism among listed firms. Merging agency and socioemotional wealth (SEW) arguments, this paper analyzes how effective SOP voting results are among listed family firms in terms of CEO compensation efficiency and equity. Using a sample of UK listed (...) firms from 2011 to 2018, our results show that SOP effectiveness is positively influenced by family ownership and is strongly moderated by family involvement in management and in governance as well as by family generation. Our findings stress the strong family effect and the ethical perceptions of family shareholders on SOP voting, showing how family participation in the firm encourages fairer and more aligned CEO compensation packages. SOP institutional and practical implications oriented to preserve shareholder value and family wealth are finally outlined. (shrink)

In Western countries, the ideal professional and ethical attributes of healthcare providers and the ideal patient-doctor relationship have been analysed in detail. Other cultures, however, may have different norms, arising in response to diverse healthcare needs, cultural values and offering alternative perspectives. In this paper, drawing a case study, we introduce the concept of Shinmi, used in Japan to describe a desirable approach to medical care. Shinmi means kind or cordial in Japanese. In the medical context, it refers to doctors (...) treating patients with a degree of emotional closeness as if they were the doctors’ own family. We analyse the concept of Shinmi, drawing on virtue ethics. We distinguish two different elements to a Shinmi-na attitude. As illustrated in our example, excessive Shinmi can be problematic for patients and doctors. Furthermore, elements of Shinmi may conflict with existing Western values (for example, norms that encourage emotional detachment and discourage doctors’ treatment of family members). However, if pursued appropriately, we argue that a balanced Shinmi-na approach can be conducive to the goals of medicine. The concept of Shinmi may be valuable for medical students, in Japanese and potentially other health care systems, and help them to cultivate a virtuous approach to meeting the emotional needs of patients.
