This paper presents a new theoretical justification for the Cournot–Bertrand model to arise in equilibrium when firms have, at the outset, the same cost structure and sell symmetrically differentiated products. The Cournot–Bertrand model assumes some firms compete on price, adjusting their production to meet demand, while others set quantities and let their price adjust until market equilibrium is reached. We show that this may occur endogenously due to the possibility of entry, which may be deterred when some of the incumbents (...) decide to set prices, while others free ride on this behavior and choose quantities.

The development of neuropsychological assessment methods using virtual reality (VR) is a valid and promising option for the detection of cognitive impairment in the older people, focusing on activities composed of tasks of multiple demands. This study verified the association of age, schooling, and general cognitive status on the performance of neurologically healthy older adults in ECO-VR, a virtual reality task of multiple demands for neuropsychological assessment. A total of 111 older adults answered a sociodemographic questionnaire, the Mini Mental State (...) Examination, the Vocabulary subtest of the Wechsler Intelligence Scale for Adults (third edition), and the ECO-VR. Correlation analyses, multiple linear regression, and comparisons between groups (effects by age and schooling groups) were used to evaluate the results. The ECO-VR total score was significantly associated with age, years of education, MMSE, and Vocabulary subtest. The linear regression models identified that age was the main predictor for total score and rule breaking of ECO-VR. According to the univariate analysis, it was identified the main effect of age group and schooling group in the total ECO-VR score, but there was no interaction effect. The results are discussed in order to understand the role of sociodemographic characteristics in the performance of older adults in a virtual reality task of multiple demands. It was also verified the possibility use of virtual reality for neuropsychological assessment of older adults. (shrink)

The primary objective of this study is to revisit Thomas Aquinas’ notion of justice in light of the author’s own considerations regarding false testimony, specifically in its relation to sin. The intention is to emphasize, within the philosopher, theologian, and advisor’s thinking, the non-sacrificial dimension of justice, which aligns with a testimonial view of cultural evolution and, consequently, philosophical and theological thought. These topics will be addressed through an examination of the discussion surrounding antisemitism in S. Thomas Aquinas, a discussion (...) conducted and explored by Hippolyte Gayraud in his book titled L’Antisémitisme de Saint Thomas D’Aquin (The Antisemitism of Saint Thomas Aquinas). (shrink)

In recent years, online “involuntary celibate” or “incel” communities have been linked to various deadly attacks targeting women. Why do these men react to romantic rejection with not just disappointment, but murderous rage? Feminists have claimed this is because incels desire women as objects or, alternatively, because they feel entitled to women’s attention. I argue that both of these explanatory models are insufficient. They fail to account for incels’ distinctive ambivalence toward women—for their oscillation between obsessive desire and violent hatred. (...) I propose instead that what incels want is a Beauvoirian “Other.” For Beauvoir, when men conceive of women as Others, they represent them as simultaneously human subjects and embodiments of the natural world. Women function then as sui generis entities through which men can experience themselves as praiseworthy heroes, regardless of the quality of their actions. I go on to give an illustrative analysis of Elliot Rodger’s autobiographical manifesto, “My Twisted World.” I show how this Beauvoirian model sheds light on Rodger’s racist and classist attitudes and gives us a better understanding of his ambivalence toward women. It therefore constitutes a powerful and overlooked theoretical alternative to accounts centered on objectification and entitlement. (shrink)

Previous research suggests that all-inclusive superordinate categories, such as “citizens of the world” and “humans,” may represent different socio-psychological realities. Yet it remains unclear whether the use of different categories may account for different psychological processes and attitudinal or behavioral outcomes. Two studies extended previous research by comparing how these categories are cognitively represented, and their impact on intergroup helping from host communities toward migrants. In a correlational study, 168 nationals from 25 countries perceived the group of migrants as more (...) prototypical of the superordinate category “citizens of the world” than their national group, whereas no differences in prototypicality occurred for the category “humans.” Identification with “citizens of the world” was positively associated with a disposition to oppose helping migrants and to offer dependency-oriented help. However, identification with “humans” was positively associated with helping in general, and with offering dependency- and autonomy-oriented help; and negatively associated with opposition to helping. The experimental study manipulated the salience of “citizens of the world” vs. “humans” vs. control category, among 224 nationals from 36 countries. Results showed that the salience of “humans” triggered higher entitativity and essentialist perceptions, and dual-identity representations. No differences due to salience were found for representations of relative ingroup prototypicality or helping responses. Overall, these findings suggest that the interchangeable use of different labels is problematic, considering these might activate different representations, and thus, are likely to lead, in some circumstances, to different attitudinal or behavioral outcomes.

One of the key insights of Simone de Beauvoir’s The Second Sex is the idea that gender-based subordination is not just something done to women, but also something women do to themselves. This raises a question about ethical responsibility: if women are complicit, or actively implicated in their own oppression, are they at fault? Recent Beauvoir scholarship remains divided on this point. Here, I argue that Beauvoir did, in fact, ethically criticize many women for their complicity, as a sign of (...) what she called “bad faith”. I challenge recent accounts by Nancy Bauer and Manon Garcia, who both read Beauvoir as exonerating complicit women. According to this reading, women emerge as human “freedoms” within a social world where a “destiny” of inferiority is already prepared for them. Their self-subordination is then an inevitable product of acting in a patriarchal world. I argue, however, that this interpretation generates a crucial tension, leading Bauer and Garcia to call on women to stop being complicit, while also claiming they cannot avoid complicity. I propose instead a different interpretation, on which feminine complicity is often fueled by criticizable ethical attitudes that are far from inevitable. By revisiting Beauvoir’s notion of “bad faith”, I show that this account is compatible with recognizing the limitations imposed on women’s agency and I show that this feminist ethical criticism is itself an important part of a collective project of social transformation.

Some plausibly necessary a posteriori theoretical claims include ‘water is H 2 O’, ‘gold is the element with atomic number 79’, and ‘cats are animals’. In this paper I challenge the necessity of the third claim. I argue that there are possible worlds in which cats exist, but are not animals. Under any of the species concepts currently accepted in biology, organisms do not belong essentially to their species. This is equally true of their ancestors. In phylogenetic systematics, monophyletic clades (...) such as the animal kingdom are composed of an ancestral stem species and all of its descendants. If the stem species had not existed, neither would the clade. Thus it could have been the case that all the organisms which actually belong to the animal kingdom might have existed yet not have been animals. (shrink)

Life is a self-maintaining process based on metabolism. Something is said to be alive when it exhibits organization and is actively involved in its own continued existence through carrying out metabolic processes. A life is a spatio-temporally restricted event, which continues while the life processes are occurring in a particular chunk of matter (or, arguably, when they are temporally suspended, but can be restarted at any moment), even though there is continuous replacement of parts. Life is organized in discrete packages, (...) particular cells and multicellular organisms with differing degrees of individuality. Biological species, too, have been shown to be individuals, and not classes, as these collections of organisms are spatio-temporally localized, restricted, continuous, and somewhat cohesive entities, with a definite beginning and end. Assuming that all life on Earth has a common origin, all living organisms, cells, and tissues descending from this origin exhibit continuity of the life processes at the cellular level, as well as many of the features that define the individual character of species: spatio-temporal localization and restriction, continuity, historicity, and cohesiveness. Therefore, life on Earth is an ontological individual. Independent origins of life will have produced other such individuals. These provisionally called ‘life-individuals’ constitute a category of organization of life which has seldom been recognized. The discovery of at least one independent life-individual would go a long way toward the project of the universality of biology. (shrink)

The United Nations World Tourism Organization has acknowledged 2020 as the worst year in tourism history due to the worldwide pandemic COVID-19. Destinations, tourists, local communities, stakeholders, and residents, and their daily activities were affected. Thus, wellbeing and resilience are two crucial variables to help the industry and the people recover. This research aims to analyze early positive approaches and attitudes to respond to the negative impact of COVID-19 in tourism everyday activities that have at its core wellbeing and resilience, (...) the two main variables of the Positive Psychology field of studies. A systematic literature review was conducted, following PRISMA guidelines to achieve this aim. The research was done using the Online Knowledge Library and all the available databases. The research led to 32 articles that were screened using the inclusion and exclusion criteria. A total of 18 scientific articles met all criteria. Overall, results show that a positive and resilient approach to deal with the adverse outcomes of the pandemic is a concern for stakeholders and the future of the organizations in the tourism and hospitality sector, as is tourists’ wellbeing. However, less research has been done on wellbeing and a clear lack of research regarding residents’ wellbeing and resilience is evident. A deeper study of wellbeing and resilience in tourism is needed, and actual practices and interventions to ensure that all tourism actors have the resources to overcome the pandemic and restart the industry’s daily lives feeling well and safe.

Animalism is prima facie the most plausible view about what we are; it aligns better with science and common sense, and is metaphysically more parsimonious. Thought experiments involving the brain, however, tend to elicit intuitions contrary to animalism. In this paper, I examine two classical thought experiments from the literature, brain transplant and cerebrum transplant, and a new one, cerebrum regeneration. I argue that they are theoretically possible, but that a scientifically informed account of what would actually happen shows that (...) in none of the cases would the person be separated from the animal. Our intuitions in these cases, when adequately informed by neuroscience, do not conflict with animalism – rather, they suggest a correction of the animalist position: the persisting animal should be at least minimally sentient. Sentience animalism is a new formulation of the animalist account of personal identity that allows us to reconcile facts about our biological persistence conditions with the intuition that human persistence should involve some kind of psychological continuity.

This paper aims, on the one hand, to determine the valid span of the diagram of unequal hours and, on the other, to find a mathematical expression for the error. It is found that the diagram is valid for the two days of the equinoxes and for the times when the sun is on the horizon or on the meridian. This subject has previously been treated by Delambre in 1819 and Drecker in 1925, but not comprehensively.

At the end of 2017, Kristen Roupenian’s short story, Cat Person, went viral. Published at the height of the #MeToo movement, it depicted a ‘toxic date’ and a disturbing sexual encounter between Margot, a college student, and Robert, an older man she meets at work. The story was widely viewed as a relatable denunciation of women’s powerlessness and routine victimization. In this paper, I push against this common reading. I propose an alternative feminist interpretation through the lens of Simone de (...) Beauvoir’s notion of narcissism: a form of alienation that consists in making oneself both the subject and the ultimate project of one’s life. Framing Margot as a narcissist casts her as engaging, not in subtly coerced, undesired sex, but rather in sex that is desired in a tragically alienated way. I argue that Beauvoir’s notion of narcissism is an important tool for feminists today – well beyond the interpretation of Cat Person. It presses us to see systematic subordination not just as something done to women, but also as something women do to themselves. This in turn highlights the neglected role of self-transformation as a key aspect of feminist political resistance. (shrink)

Summary The first attempt at a classification of sundials appeared only in 1953, in the catalogue established by Henri Michel for the Museum of Liège. It was immediately followed, in the same year, by the article by Kathleen Higgins, exclusively dedicated to this topic. The influence of this second study has spread out throughout the numerous articles on sundials that have been subsequently published. The aim of the present paper is to bring some order to these two old classifications, which (...) are in fact quite similar and were sufficiently valid at the time, and to propose a new approach to the problem based, for the first time, on principles directly linked to astronomy and geometry. Moreover, this latter approach has the advantage of a flexibility in its application to all kinds of sundial collections. (shrink)

Summary The analemmatic sundial was briefly presented for the first time in 1640 by the French mathematician Vaulezard and was described in more detail by him in 1644. The analemmatic dial is the last genuine sundial to be invented and it has attracted the attention of some important scholars such as Foster and Lalande. Although perfect from the very beginning, it had the unusual particularity of inspiring several unfortunate attempts at its improvement as well as being at the origin of a few other types of analemmatic dials, which met with a certain success. We provide here the trigonometric proof and for the first time, the geometric proof of its astronomical validity by closely following the construction method of Vaulezard. We also make a comprehensive survey of the different kinds of analemmatic sundials and of their literature. (shrink)

In two experiments, we examined the impact of color on cognitive performance by asking participants to categorize stimuli presented in three different colors: red, green, and gray (baseline). Participants were either asked to categorize the meaning of words as related to the concepts of “go” or “stop” (Experiment 1) or to indicate if a neutral verbal stimulus was a word or not (lexical decision task, Experiment 2). Overall, we observed performance facilitation in response to go stimuli presented in green (vs. (...) red or gray) and performance inhibition in response to go stimuli presented in red. The opposite pattern was observed for stop‐related stimuli. Importantly, results also indicated that color might also be used to categorize neutral stimuli. Overall, these findings provide support to the green‐go and red‐stop color associations and test the potential functional autonomy acquired by these colors and the boundary conditions to their effects on stimuli categorization.

BackgroundWomen survivors of breast cancer treatments face significant challenges around initiation or maintenance of physical activity as they transit to recovery. Embracing their needs and preferences is important to increase adherence. This study aimed to explore the perspectives of Portuguese women survivors of breast cancer regarding regular performance of PA and individual choices and strategies that should be considered in designing effective interventions.MethodsThe individual semi-structured interviews were analyzed through thematic analysis, following an inductive process, seeking to identify the barriers, facilitators, (...) and particular influencing circumstances associated with regular PA.ResultsFour themes and several contextual, emotional, physical, and social factors were identified as determinants of regular PA. Guilt, women’s duties, and altruism to help close relatives were identified as emotional and cultural factors that are less-found in the existing literature. PA showed influence both from health professionals’ counseling and from knowledge and beliefs held by these women.ConclusionWhile confirming the already-known impact of breast cancer diagnosis and treatments on PA, which redefine participants’ availability to be active, the findings highlight beliefs and specific emotional factors that should be considered when planning culturally sensitive interventions.

Em edição da Imprensa da Universidade de Coimbra, Margarida I. Almeida Amoedo disponibiliza agora a tradução desse curso, enquadrando-o no contexto próximo da obra orteguiana.

Within this paper, we adopt a qualitative process approach to explore how ethical judgments are influenced by spatio-cultural meanings applied to social entrepreneurship in the context of Mozambique. We analyse how such ethical judgments emerged using data gathered over a 4 year period in Maputo. Our findings illustrate three modes used to inform ethical judgments: embracing, rejecting and integrating. These describe how ethical judgments transpire as participants evaluate social entrepreneurship drawing upon related global normative meanings and those embedded within the (...) local context. This analysis offers a critical contribution regarding how ethical judgments regarding social entrepreneurship evolve from negotiation and interaction within a context of multiple spatio-cultural meanings.

Jewish Law as Rebellion is unconventional and controversial in its approach to the world of Jewish Law and its response to religious crises. The book delves into the contemporary application and development of halacha and pointedly protests many accepted methods and ideals, offering new solutions to existing halachic dilemmas. Rabbi Cardozo discusses hot topics such as same-sex marriage, conversion, and religion in the State of Israel and presents a critical analysis and explanation of the application of halacha.

Life on Earth descends from a common ancestor. However, it is likely that there are other instances of life in the universe. If so, each abiogenesis event will have given rise to an independently originated life clade, of which Earth-life is an example. In this paper, I argue that the set of all IOLCs in the universe forms a Darwinian population subject to natural selection, with more widely dispersed IOLCs being less likely to face extinction. As a result, we should (...) expect that, over time, more planets will become inhabited by fewer, more successful IOLCs. (shrink)

ABSTRACTPrevious research has revealed a stable preference for words with inward consonantal-articulation patterns, over outward-words. Following the oral approach-avoidance account suggesting that the in–out effect is due to the resemblance between consonantal-articulations patterns and ingestion/expectoration, recent findings have shown that when judging inward-outward names for objects with particular oral functions, valence did not modulate the effect while the oral function did. To replicate and examine further the role of edibility and valence in shaping the in–out effect, we asked participants to (...) rate inward and outward names for edible and non-edible products while controlling for valence. Results revealed that the motor-to-affect link was only observed for edible products, regardless of valence. (shrink)

In The Expanse, the future of humanity is constantly at stake. In The Expanse vestiges of an ancient alien civilization with incredibly advanced technology have been found—which eventually permits human interstellar expansion through the gates. James Lenman argues that, even if we agree that biodiversity is a good thing, it only means that it's good that there should be natural diversity while life exists on Earth. While we might not be facing interplanetary war or the unpredictable consequences of ancient alien (...) technology, many serious dangers face the human species today. We are quite resilient and have survived numerous disasters in the past, including floods, earthquakes, famine, pandemics, and wars. Small population size and restricted distribution range are factors that increase a species’ extinction risk. Interplanetary expansion could potentially bring about speciation, which means the separation of Homo sapiens into different species. (shrink)

This paper addresses the question ‘what is an organism?’. Extant theories of organismality only provide a partial answer because they do not include an account of composition on which an ontology of living entities can be based. Here we develop a new account of what organisms are, based on a naturalistic answer to the special composition question, the bound state view. We argue that physical structure, including the existence of a boundary, is essential for life, and that, therefore, organisms are (...) a particular kind of composite physical object – living objects. The bound state account of composition explains how composite physical objects exist in the world, and the property ‘life’ distinguishes the subset of those objects which are organisms. Our view obviates the need for disjunctive accounts of composition for living and non-living entities, placing ‘organism’ within the context of a broader scientific ontology, while at the same time providing a clear criterion of organismality that can be used in adjudicating problematic cases of biological individuality.

The representation of color by pictures raises worthwhile questions for philosophers and psychologists. Moreover, philosophers and psychologists interested in answering these questions will benefit by paying attention to each other's work. Failure to recognize the potential for interdisciplinary cooperation can be attributed to tacit acceptance of the resemblance theory of pictorial color. I argue that this theory is inadequate, so philosophers of art have work to do devising an alternative. At the same time, if the resemblance theory is false, then (...) color depiction has interesting implications for color science. Empirical researchers must rethink the widespread assumption that color recognition requires color constancy. I suggest that a neuropsychological account of color recognition will be instrumental to completing the philosophical task, but by the same token scientists might do well not to proceed without casting an eye to the work of philosophers of art.

This collection of seventeen brand new essays critically examines just how and in what form the notion of imagination (...) illuminates fundamental problems in the philosophy of art. (shrink)
