Human errors are widely considered among the major causes of road accidents. Furthermore, it is estimated that more than 90% of vehicle crashes causing fatal and permanent injuries are directly related to mental tiredness, fatigue, and drowsiness of the drivers. In particular, driving drowsiness is recognized as a crucial aspect in the context of road safety, since drowsy drivers can suddenly lose control of the car. Moreover, the driving drowsiness episodes mostly appear suddenly without any prior behavioral evidence. The present (...) study aimed at characterizing the onset of drowsiness in car drivers by means of a multimodal neurophysiological approach to develop a synthetic electroencephalographic -based index, able to detect drowsy events. The study involved 19 participants in a simulated scenario structured in a sequence of driving tasks under different situations and traffic conditions. The experimental conditions were designed to induce prominent mental drowsiness in the final part. The EEG-based index, so-called “MDrow index”, was developed and validated to detect the driving drowsiness of the participants. The MDrow index was derived from the Global Field Power calculated in the Alpha EEG frequency band over the parietal brain sites. The results demonstrated the reliability of the proposed MDrow index in detecting the driving drowsiness experienced by the participants, resulting also more sensitive and timely sensible with respect to more conventional autonomic parameters, such as the EyeBlinks Rate and the Heart Rate Variability, and to subjective measurements.

In the early stages of the COVID-19 pandemic, Italy, Spain, New York, and Hong Kong stood out for the ir high rates of infections. Given this scenario, a web-based international multisite and cross-sectional study was conducted between April and May 2020 to investigate the psychological impact of the pandemic and the restrictions imposed by the governments in these countries. We expected similar patterns in European countries, and no significant differences in terms of psychological impairment between Hong Kong and (...) the other areas. Participants were 1955 adults from the above-mentioned areas. We assessed anxiety, depression, COVID-19-related threats, and perceived burden of restrictive measures. Two-explorative factor analyses with Promax rotation identified COVID-19-related factors: personal physical threat, personal economic threat, global economic threat, and restriction-related burden. ANOVAs studied locations’ differences and two-separate hierarchical multiple regression analyses by location determined whether and how COVID-19-related variables were associated with anxiety and depression, adjusting for age and sex. Italy and Hong Kong showed higher anxiety than Spain ; Hong Kong scored higher on depression than Italy and Spain, which highlighted the lowest mean-score. New York participants showed the poorest mental health conditions. Anxiety was predicted by restriction-related burden and personal economic threat in New York and Hong Kong ; by global economic threat and restriction-related burden in Italy ; and by personal physical threat in Spain. Depression was predicted by restriction-related burden and personal economic threat in New York and Hong Kong ; by global economic threat in Italy ; and no predictors emerged in Spain. Findings could contribute to understanding the specific impact of the pandemic on people’s psychological health in each area, along with the factors that impacted mental health. This information may be useful to implementing prevention interventions in case of restrictions. (shrink)

This article examines whether people share the Gettier intuition (viz. that someone who has a true justified belief that p may nonetheless fail to know that p) in 24 sites, located in 23 countries (counting Hong Kong as a distinct country) and across 17 languages. We also consider the possible influence of gender and personality on this intuition with a very large sample size. Finally, we examine whether the Gettier intuition varies across people as a function of their disposition (...) to engage in “reflective” thinking. (shrink)

Background Gerontechnologies are increasingly used in the care for older people. Many studies on their acceptability and ethical implications are conducted, but mainly from the perspective of principlism. This narrows our ethical gaze on the implications the use of these technologies have. Research question How do participants speak about the impact that gerontechnologies have on the different phases of care, and care as a process? What are the moral implications from an ethic of care perspective? Research design Secondary analysis of (...) semi-structure interviews, whose segments on specific technologies were analysed through reflexive thematic analysis. Participants and research context Sixty-seven Swiss stakeholders involved in the use of gerontechnologies, including professional caregivers, informal caregivers, and older persons themselves. Ethical considerations The research study was evaluated by the Ethics Commission of Northwest and Central Switzerland (EKNZ). All participants received an information document before the interview date detailing the purpose, procedure, and anonymization measures. After explaining the study during the agreed upon interview time and upon receiving their written informed consent, the interview process began. Findings/results Four themes are identified: Identifying care needs, Taking responsibility, Hands-on work, Responding to care. As part of these themes, many codes highlighting the ambivalent impact of gerontechnologies are created, ranging from ‘Expanded capacity for…identifying care needs’ to ‘Create new & (un)necessary…hands-on work’. The moral implications of these results from the care ethics perspective are discussed, through the ethical elements of: attentiveness, responsibility, competence, and responsiveness. Conclusions The moral implications of gerontechnologies on care phases from the care ethics perspective open up several questions on whether they actually help give care a central role in social life and provide more competent care.

Perception is said to have assertoric force: It inclines the perceiver to believe its content. In contrast, perceptual imagination is commonly taken to be non-assertoric: Imagining winning a piano contest does not incline the imaginer to believe they actually won. However, abundant evidence from clinical and experimental psychology shows that imagination influences attitudes and behavior in ways similar to perceptual experiences. To account for these phenomena, I propose that perceptual imaginings have implicit assertoric force and put forth a theory—the Prima (...) Facie View—as a unified explanation for the empirical findings reviewed. According to this view, mental images are treated as percepts in operations involving associative memory. Finally, I address alternative explanations that could account for the reviewed empirical evidence—such as a Spinozian model of belief formation or Gendler’s notion of alief—as well as potential objections to the Prima Facie View.

Built on the integrated theoretical framework of antecedents of flow and expectation confirmation model, this research investigates the way flow experience drives the online students’ intention to engage in online English teaching platforms. This study focused on the online students engaged in online English learning platforms in Taiwan. A total of 500 online students were selected. An online survey was conducted with the help of a marketing research agency located in Taiwan. According to the results, the online students’ flow experience (...) was found to be in a significant relationship with continuous intention. The antecedents, including perceived enjoyment, challenge, and situational involvement, were found to be in a positive relationship with flow experience; however, confirmation and perceived vividness did not have significant effects on the flow. Furthermore, flow and confirmation were found to be in a significant relationship with perceived usefulness and satisfaction. Moreover, perceived usefulness was found to be in a significant relationship with satisfaction and continuous intention. Lastly, satisfaction was found to be in a significant relationship with continuous intention. Finally, the questions proposed in this research with their empirical findings offer profound understanding for establishing a well-devised online English learning platform that can motivate online learning. These results and managerial implications for online English language platforms are innovative and significant in practice. (shrink)

According to a widespread view, a complete explanatory reduction of all aspects of the human mind to the electro-chemical functioning of the brain is at hand and will certainly produce vast and positive cultural, political and social consequences. However, notwithstanding the astonishing advances generated by the neurosciences in recent years for our understanding of the mechanisms and functions of the brain, the application of these findings to the specific but crucial issue of human agency can be considered a “pre-paradigmatic science” (...) (in Thomas Kuhn’s sense). This implies that the situation is, at the same time, intellectually stimulating and methodologically confused. More specifically—because of the lack of a solid, unitary and coherent methodological framework as to how to connect neurophysiology and agency—it frequently happens that tentative approaches, bold but very preliminary claims and even clearly flawed interpretations of experimental data are taken for granted. In this article some examples of such conceptual confusions and intellectual hubris will be presented, which derive from the most recent literature at the intersection between neurosciences, on the one hand, and philosophy, politics and social sciences, on the other hand. It will also be argued that, in some of these cases, hasty and over-ambitious conclusions may produce negative social and political consequences. The general upshot will be that very much has still to be clarified as to what and how neurosciences can tell us about human agency and that, in the meantime, intellectual and methodological caution is to be recommended.

Among the various motivations that may lead to the idea that truth is relative in some non-conventional sense, one is that the idea helps explain how there can be ‘‘ faultless disagreements’’, that is, situations in which a person A judges that p, a person B judges that not-p, but neither A nor B is at fault. The line of argument goes as follows. It seems that there are faultless disagreements. For example, A and B may disagree on culinary matters (...) without either A or B being at fault. But standard semantics has no room for such a case, so there is something wrong with standard semantics. The best way to amend it is to add a new parameter that is relevant to the truth or falsity of what A and B judge, presumably, something related to personal taste. The aim of the paper is to show that this line of argument is flawed. It is true that standard semantics has no room for faultless disagreements. But there is nothing wrong with this, for it should not be assumed that such disagreements exist. (shrink)

In order to accommodate for the present shortage of oocyte donors, oocyte-donation programs place ads in college newspapers and provide large monetary compensation to encourage participation. Large compensation acts as a strong incentive for young women to undergo the potentially risky procedure of donation. In this enticing situation, it is particularly important for programs to fully inform prospective donors of the risks of the procedure so that they can accurately weigh the costs and benefits of donating. However, because oocyte-donor programs (...) must alleviate the shortage of donors if they wish to maintain a financially viable business, there is reason to fear that they may minimize or misrepresent risks when recruiting egg donors. In this pilot study, the risk information provided by programs (n=19) to prospective oocyte donors in a preliminary phone call inquiry was investigated. The majority of the programs provided incomplete and/or inaccurate risk information. Policy changes are recommended to reduce the potential for undue influence and to standardize and regulate the risk information provided to prospective egg donors. (shrink)

This essay explores the connection between representation and explanation in the sciences. I suggest that scientific representation schemes be viewed as pragmatic tools for acquiring the sort of articulated awareness that is the hallmark of nontrivial knowledge. Crystal field theory in chemistry illustrates this perspective. Certain representations achieve the status of being paradigmatically explanatory, thereby shaping models of intelligibility. In turn, these explanatory preferences serve largely to define and differentiate disciplinary communities by implicitly endorsing particular epistemic aims and values. In (...) this way, the pragmatic nature of explanatory discourse effectively grants its intellectual utility. (shrink)

According to simulation or shared-substrates models of emotion recognition, our ability to recognize the emotions expressed by other individuals relies, at least in part, on processes that internally simulate the same emotional state in ourselves. The term “emotional expressions” is nearly synonymous, in many people's minds, with facial expressions of emotion. However, vocal prosody and whole-body cues also convey emotional information. What is the relationship between these various channels of emotional communication? We first briefly review simulation models of emotion recognition, (...) and then discuss neuroscientific evidence related to these models, including studies using facial expressions, whole-body cues, and vocal prosody. We conclude by discussing these data in the context of simulation and shared-substrates models of emotion recognition. (shrink)

We argue that there are three coherent, nontrivial notions of basic-ness: conceptual basic-ness, biological basic-ness, and psychological basic-ness. There is considerable evidence for conceptually basic emotion categories (e.g., “anger,” “fear”). These categories do not designate biologically basic emotions, but some forms of anger, fear, and so on that are biologically basic in a sense we will specify. Finally, two notions of psychological basic-ness are distinguished, and the evidence for them is evaluated. The framework we offer acknowledges the force of some (...) of the objections to basic emotion theory whilst demonstrating that the notion of a basic emotion, once properly reformulated, is still of scientific value.

A fairly simple theory of the semantics of tense is obtained by combining three claims: (i) for any time t, a present-tense sentence `p' is either true or false at t; (ii) for any time t0 earlier than t, the future-tense sentence `It will be the case that p at t' is true at t0 if `p' is true at t, false otherwise; (iii) for any time t0 later than t, the past-tense sentence `It was the case that p at (...) t' is true at t0 if `p' is true at t, false otherwise. This theory, which has been called the theory of timeless truth, is often dismissed on the basis of its alleged incapacity to comply with indeterminism. Here, instead, it will be suggested that there is no reason to be dismissive. Section 1 provides some elucidations about the theory. Sections 2 and 3 explain how a foregone objection to it can be resisted. Sections 4 and 5 show that there is a plausible sense in which (i)-(iii) are compatible with indeterminism. Sections 6 and 7 dispel some misunderstandings that may lead to think that indeterminism is not vindicated in some important sense other than that outlined. (shrink)

Andrea Sangiacomo offers a new understanding of Spinoza's moral philosophy, how his views significantly evolved over time, and how he himself struggled during his career to develop a theory that could speak to human beings as they actually are--imperfect, passionate, and often not very rational.

The central contention of this article is that the classificatory scheme of contemporary affective science, with its traditional categories of emotion, anger, fear, and so on, is no longer suitable to the needs of affective science. Unlike psychological constructionists, who have urged the transition from a discrete to a dimensional approach in the study of affective phenomena, I argue that we can stick to a discrete approach as long as we accept that traditional emotion categories will have to be transformed (...) in order to do any scientific work. I conclude by articulating some general rules for turning traditional emotion categories into suitable scientific tools. (shrink)

In this paper I develop a conception of joint practical deliberation as a special type of shared cooperative activity, through which co-deliberators jointly accept reasons as applying to them as a pair or group. I argue, moreover, that the aspiration to deliberative “pairhood” is distinguished by a special concern for mutuality that guides each deliberator’s readiness to accept a given consideration as a reason-for-us. It matters to each of us, as joint deliberators, that each party’s (individual) reasons for accepting something (...) as a reason-for-us support a conception of our relationship as one characterized by mutual, non-instrumental concern for one another.

The paper puts forward a new skeptical solution to Kripke’s Wittgenstein’s rule-following paradox, a solution which revolves around the idea that human communication does not require meaning facts - at least as defined by Kripke. After a brief discussion of the paradox, I explain why I think that Kripkenstein’s solution needs revision and argue that the main goal of a skeptical solution to the rule-following paradox should be that of showing that communication does not require meaning. After that, I offer (...) two arguments for the thesis that communication does not require meaning. The first argument instantiates a rather direct strategy and focuses on the description of a concrete case of communication without meaning. The second one is more indirect in that I start by describing a world in which, although there are meaning facts, communication does not depend on them. The paper’s last section deals with the issue of meaning talk. (shrink)

This paper defends the thesis that counterfactuals are strict conditionals. Its purpose is to show that there is a coherent view according to which counterfactuals are strict conditionals whose antecedent is stated elliptically. Section 1 introduces the view.

Section 3 compares the view with a proposal due to Aqvist, which may be regarded as its direct predecessor. Sections 4 and 5 explain how the (...) view di ers from the theories of counterfactuals advocated by Stalnaker and Lewis, and from some contextualist strict conditional accounts of counterfactuals that have emerged recently. Finally, section 6 addresses the thorny issue of disjunctive antecedents. (shrink)

Background The worldwide increase in older persons demands technological solutions to combat the shortage of caregiving and to enable aging in place. Smart home health technologies (SHHTs) are promoted and implemented as a possible solution from an economic and practical perspective. However, ethical considerations are equally important and need to be investigated. Methods We conducted a systematic review according to the PRISMA guidelines to investigate if and how ethical questions are discussed in the field of SHHTs in caregiving for older (...) persons. Results 156 peer-reviewed articles published in English, German and French were retrieved and analyzed across 10 electronic databases. Using narrative analysis, 7 ethical categories were mapped: privacy, autonomy, responsibility, human vs. artificial interactions, trust, ageism and stigma, and other concerns. Conclusion The findings of our systematic review show the (lack of) ethical consideration when it comes to the development and implementation of SHHTs for older persons. Our analysis is useful to promote careful ethical consideration when carrying out technology development, research and deployment to care for older persons. Registration We registered our systematic review in the PROSPERO network under CRD42021248543. (shrink)

Pedagogy of Life takes its readers through the echoing stories of the half-century, historical Cultural Revolution of China to the literate lifeworld today. Rosa Hong Chen offers a gripping array of personal and kindred stories woven into the power of words and empathy of art through the volutes of writing and dancing for life, expressing genera of warm melancholy, weighty sensations, compulsive sobs, and refrained elation. It is for the existential history of individual lives and communal sharing that life (...) creates a pedagogical condition of possible experiences. Life itself forms a historical and social path of human growth and maturation. In a philosophical and educational autoethnographical inquiry, the author examines the nature of literacy for those marginalized and oppressed; Chen explores how one's name and the ways in which that name is used affect a person's self-knowing and knowing of the world. This book exemplifies the idea that individuals' autobiographical stories are importantly connected to wider cultural, political, and social meaning and understanding. Pedagogy of Life echoes readers' musings, affects, relations, imagination, choice, learning, teaching, and much more, because we, each and all, have our own names, ways of uttering, writing, and dancing, and, ultimately, our own ways of living, knowing, and becoming.

This paper reports on the findings of a qualitative study to understand how active adherence to the Christian faith influences the way SME owner-managers conceptualise their business practices. The study was based on in-depth interviews with 21 Christian SME owner-managers in Germany and the UK. Using a socio-psychological approach, the data analysis yielded a range of linguistic and conceptual resources that are peculiar to Christian discourse and that have the potential to influence business activity in rather distinctive ways. This paper (...) particularly focuses on those Christian concepts that could be regarded as distinct 'frames' for action. It outlines what effect these concepts had on the respondents and how they were related to business practices. The paper also discusses how this study could inform further research into the influence of other socio-cultural forms of identity on economic actors' conceptualisations of their own practice.

Is autonomy – governing yourself – compatible with letting yourself be governed by trust? This paper argues that autonomy is not only compatible with appropriate trust but actually requires it. Autonomy requires appropriate trust because it is undermined by inappropriate mistrust. An autonomous agent treats herself as answerable for her action-guiding commitments, where answerability requires openness to the rational influence of external, critical perspectives on those commitments. This openness to correction makes one vulnerable to manipulation and can be exploited in (...) ways that undermine autonomy instead of supporting it. We argue that autonomy is undermined by inappropriate trust, and that the inappropriateness lies in the agent’s failure to manifest appropriate responsiveness to evidence of untrustworthiness in the one trusted. The problem isn’t that autonomy requires dispensing with trust but that trust must itself be governed by appropriate responsiveness to evidence of untrustworthiness. Our view confronts two challenges. One challenge lies in explaining why you shouldn’t treat your vulnerability to manipulation as a general reason to let your trusting disposition lapse into an untrusting one. We argue that there is no such general reason to let your responsiveness to evidence of untrustworthiness be supplanted by a suspicious disposition to seek and require positive evidence of trustworthiness. A second, and deeper, challenge arises from the fact that in some especially sophisticated cases of manipulation there is no evidence of untrustworthiness to which you could respond. We argue that you cannot rationally cope with even this unresolvable risk of exploited trust by trusting only yourself. (shrink)

Flipped learning could improve the learning effectiveness of students. However, some studies have pointed out the limitations related to flipped classrooms because the content of the flipped course does not vary according to the needs of the students. On the other hand, adaptive teaching, which customizes the learning mode according to the individual needs of students, can make up for some of the shortcomings of flipped teaching. This study combines adaptive teaching with flipped teaching and applies it to face-to-face classroom (...) activities. The purpose of this research is to explore whether the implementation of flipping and adaptive learning in a computer programming course can improve the learning effectiveness of students. The experimental subjects of this study are the sophomore students in the Department of Information Management. The flipped classroom with adaptive instruction has been realized in the limited course time. This study uses questionnaires to collect pre- and post-test data on the “learning motivation” of students. The learning effectiveness was evaluated based on the students' previous programming course and the semester scores of this course. Research results show that the post-test “learning motivation” has improved overall compared with the pre-test, and the learning effect is significant. The results of this research not only prove the effectiveness of modern teaching theories in programming courses but also lay the foundation for future teaching design. (shrink)

German universities come under fire: in contemporary political discourse they are considered to be antiquated, inefficient and unfit for international competition. Accordingly, the German government implemented an extensive program of reforms. Following the so‐called ‘Sorbonne Declaration’, the universities shall become part of an European higher education system with comparable and compatible structures. With the focus on the field of academic teaching and learning, this essay discusses the way of defining these activities in a new, entrepreneurial way, and the implications of (...) this process within the university. The reflections lead to the thesis that the actual reforms ask for new forms of critique, because the neoliberal offer of marketable ways to teach and to learn makes the enduring asymmetry of power relations within the educational field invisible, endangers the democratic character of the university and trivializes education.

Even though he is not very explicit about it, in “Wittgenstein on Rules and Private Language” Kripke discusses two different, albeit related, skeptical theses ‒ the first one in the philosophy of mind, the second one in the philosophy of language. Usually, what Kripke says about one thesis can be easily applied to the other one, too; however, things are not always that simple. In this paper, I discuss the case of the so-called “Normativity Argument” against semantic dispositionalism (which I (...) take to be epistemological in nature) and argue that it is much stronger as an argument in the philosophy of mind than when it is construed as an argument in the philosophy of language.

Many arguments are affected by context sensitivity, because they include sentences that have different truth conditions in different contexts. Therefore, it is natural to think that a general criterion for evaluating arguments must take context sensitivity into account. One way to give substance to that thought is provided by the definition of validity offered by David Kaplan within his theory of indexicals. However, the route indicated by Kaplan is hindered by a problem whose importance is often underestimated. This paper explores (...) a different route, and outlines a definition of validity that does not run into that problem. Its moral is that Kaplan's definition is not the only plausible definition. This is not to say that the definition outlined is the only plausible definition or that it is correct in some absolute sense. There might be equally important problems with it that the paper does not take into account. But until such problems are found and brought up, the departure from Kaplan's route remains a viable option. (shrink)

This paper employs some outcomes (for the most part due to David Lewis) of the contemporary debate on the metaphysics of dispositions to evaluate those dispositional analyses of meaning that make use of the concept of a disposition in ideal conditions. The first section of the paper explains why one may find appealing the notion of an ideal-condition dispositional analysis of meaning and argues that Saul Kripke’s well-known argument against such analyses is wanting. The second section focuses on Lewis’ work (...) in the metaphysics of dispositions in order to call attention to some intuitions about the nature of dispositions that we all seem to share. In particular, I stress the role of what I call "Actuality Constraint". The third section of the paper maintains that the Actuality Constraint can be used to show that the dispositions with which ideal-condition dispositional analyses identify my meaning addition by "+" do not exist (in so doing, I develop a suggestion put forward by Paul Boghossian). This immediately implies that ideal-condition dispositional analyses of meaning cannot work. The last section discusses a possible objection to my argument. The point of the objection is that the argument depends on an illicit assumption. I show (1) that, in fact, the assumption in question is far from illicit and (2) that even without this assumption it is possible to argue that the dispositions with which ideal-condition dispositional analyses identify my meaning addition by "+" do not exist.

In a paper called 'Definiteness and Knowability', Tim Williamson addresses the question whether one must accept that vagueness is an epistemic phenomenon if one adopts classical logic and a disquotational principle for truth. Some have suggested that one must not, hence that classical logic and the disquotational principle may be preserved without endorsing epistemicism. Williamson’s paper, however, finds ‘no plausible way of substantiating that possibility’. Its moral is that ‘either classical logic fails, or the disquotational principle does, or vagueness is (...) an epistemic phenomenon’. The moral of this paper, on the contrary, is that there is a plausible way of substantiating that possibility. The option it contemplates looks like a view that Williamson dismisses at the beginning of his paper, and that others regard as unworthy of serious consideration. (shrink)

That the maximization of quality-adjusted life years violates concerns for fairness is well known. One approach to face this issue is to elicit fairness preferences of the public empirically and to incorporate the corresponding equity weights into cost-utility analysis (CUA). It is thereby sought to encounter the objections by means of an axiological modification while leaving the value-maximizing framework of CUA intact. Based on the work of Lübbe (2005, 2009a, 2009b, 2010, forthcoming), this paper questions this strategy and scrutinizes the (...) concomitant assumptions concerning the nature of prioritization decisions. Empirical studies indicate that these premises are in fact unwarranted. People chose a certain resource allocation because they perceive it as a fair way to treat the persons concerned, not because it maximizes something valuable, and it is questionable if prioritization decision can be represented as value-maximizing choices at all. This reflection on the fundamental distinction between deontological and consequentialist reasoning bears general implications for the scope of ‘economic imperialism.’. (shrink)

Comparing the typologies of human activities developed by Beauvoir and Arendt, I argue that these philosophers share the same concept of labor as well as a similar insight that labor cannot provide a justification or evaluative measure for human life. But Beauvoir and Arendt think differently about work (as contrasted with labor), and Arendt alone illuminates the inability of constructive work to provide non-utilitarian value for human existence. Beauvoir, on the other hand, exceeds Arendt in examining the ethical implications of (...) our existential need for a plurality of free peers in a public realm. (shrink)

This paper documents the number-related properties of Dëne Sųłiné (Athapaskan). Dëne Sųłiné has neither number inflection nor numeral classifiers. Nouns are bare, occur as such in argument positions, and combine directly with numerals. With these traits, Dëne Sųłiné represents a type of language that is little considered in formal typologies of number and countability. The paper critiques one influential proposal, that of Chierchia (in: Rothstein (ed.) Events and grammar, 1998a; Natural Language Semantics 6: 339–405, 1998b), and presents an alternative number (...) typology, which introduces variation in the semantics of numerals. It will be shown that bare nouns in Dëne Sųłiné can be mass or count. Hence, the difference between count and mass cannot be expressed in terms of number, as in Chierchia. Instead, I express it in terms of atomicity. Mass nouns have nonatomic denotations, bare count nouns have atomic denotations that comprise singularities and pluralities. I also propose that numerals contain a function that accesses the singularities in a noun’s denotation. Hence they are compatible with bare count nouns, but not with mass nouns. In classifier languages, numerals denote a cardinality only; singularity-accessing functions are expressed in separate elements: the classifiers. Thus, languages like Chinese require classifiers because the numerals are semantically deficient, and not, as is assumed by Chierchia and others, the bare nouns. (shrink)

Much recent research on child language has been inspired by linguistic principles uncovered by linguists working in the generative framework. Developmental psycholinguists have demonstrated young children’s mastery of a variety of linguistic principles; mostly syntactic principles, but also some semantic principles. The present paper contributes to research on the acquisition of semantics by presenting the findings of a new experiment designed to investigate young children’s knowledge of downward entailment, which is a basic semantic property of Universal Grammar. Section 2 describes (...) how downward entailing operators work in natural languages. Section 3 addresses the issue of how a child could master the complex behavior displayed by downward entailing operators across natural languages. That section also reviews the findings of previous research on children’s knowledge of downward entailment. Section 4 presents the new experiment which was designed to investigate whether children’s knowledge of downward entailment extends to one of its logical properties, as illustrated by one of De Morgan’s laws. Section 5 offers some brief remarks on future research. (shrink)

The possibility of extraterrestrial intelligence (ETI) exists despite no observed evidence, and the risks and benefits of actively searching for ETI (Active SETI) have been debated. Active SETI has been criticized for potentially exposing humanity to existential risk, and a recent game-theoretical model highlights the Hobbesian trap that could occur following contact if mutual distrust leads to mutual destruction. We argue that observing a nearby ETI would suggest the existence of many unobserved ETI. This would expand the game and implies (...) that there may be a mechanism that prevents ETI from attacking us. As a result, the Hobbesian trap would be avoided if both parties assumed the other is not likely to attack. (shrink)
