I offer a novel solution to the problem of counterfactual skepticism: the worry that all contingent counterfactuals without explicit probabilities in the consequent are false. I argue that a specific kind of contextualist semantics and pragmatics for would- and might-counterfactuals can block both central routes to counterfactual skepticism. One, it can explain the clash between would- and might-counterfactuals as in: If you had dropped that vase, it would have broken. and If you had dropped that vase, it might have safely (...) quantum tunneled to China. Two, it can explain why counterfactuals like can be true despite the fact that quantum tunneling worlds are among the most similar worlds. I further argue that this brand of contextualism accounts for the data better than other existing solutions to the problem. (shrink)

Both definite descriptions and pronouns are often anaphoric; that is, part of their interpretation in context depends on prior linguistic material in the discourse. For example: A student walked in. The student sat down. A student walked in. She sat down. One popular view of anaphoric pronouns, the d-type view, is that pronouns like ‘she’ go proxy for definite descriptions like ‘the student who walked in’, which are in turn treated in a classical Russellian or Fregean fashion. I argue for (...) a novel version of the d-type view in which anaphoric definites are restricted existential quantifiers that presuppose discourse uniqueness, which is uniqueness of discourse referent in the context, rather than uniqueness of object in the world. In other words, the anaphoric definites ‘the student’ and ‘she’ in and presuppose that there is a single object under discussion that is a student who walked in. I further argue that, by contrast, non-anaphoric definites are restricted existential quantifiers that presuppose worldly uniqueness, that is, that there is a unique object in the world that satisfies the descriptive information. The semantics for anaphoric and non-anaphoric definites accounts for the differences in truth conditions in discourses involving the two different types of definites, improving on existing accounts. It is further supported by crosslinguistic data. The semantics is formally implemented in a static system employing quantifier domain restriction in the style of Stanley and Szabo :219–261, 2000) and extended to account for bridging definites and donkey sentences.

The classic Lewis-Stalnaker semantics for counterfactuals captures that Sobel sequences are consistent sequences, for example: a.If Sophie had gone to the parade, she would have seen Pedro dance. b.But if Sophie had gone to the parade and been stuck behind someone tall, she would not have seen Pedro dance. But reverse a sequence like this one and it no longer sounds so good, which is surprising on the classic semantics. This observation motivated Kai von Fintel and Thony Gillies to propose (...) dynamic semantic accounts of counterfactual conditionals. Subsequently, Sarah Moss defended the classic semantics against the charge that it need be abandoned in the face of these order effects, arguing that the infelicity of the reverse sequences is pragmatic. I argue that both accounts are ultimately untenable, but each account has strengths. Seeing what works and what doesn't in each account points the way to the right positive view. With this in mind, I defend a contextualist account of counterfactuals that takes conversational relevance to play a central role. (shrink)

I suspect the answer to the question in the title of this paper is no. But the scope of my paper will be considerably more limited: I will be concerned with whether certain types of considerations that are commonly cited in favor of dynamic semantics do in fact push us towards a dynamic semantics. Ultimately, I will argue that the evidence points to a dynamics of discourse that is best treated pragmatically, rather than as part of the semantics.

One of the central questions of discourse dynamics is when an anaphoric pronoun is licensed. This paper addresses this question as it pertains to the complex data involving anaphora and negation. It is commonly held that negation blocks anaphoric potential, for example, we cannot say “Bill doesn’t have a car. It is black”. However, there are many exceptions to this generalization. This paper examines a variety of types of discourses in which anaphora on indefinites under the scope of negation is (...) felicitous. These cases are not just of intrinsic interest, but I argue present serious problems for the dynamic semantic framework, which builds the licensing facts into the semantics. I argue in favor of adopting a dynamic pragmatics, a theory that explains context change through general Gricean principles, and combining it with a static, d-type theory of anaphora, in which pronouns go proxy for definite descriptions.

Context-sensitivity raises a metasemantic question: what determines the value of a context-sensitive expression in context? Taking gradable adjectives as a case study, this paper argues against various forms of intentionalist metasemantics, i.e. that speaker intentions determine values for context-sensitive expressions in context, including the coordination account recently defended by King :219–237, 2014a; in: Burgess, Sherman Metasemantics: New essays on the foundations of meaning, Oxford University Press, Oxford, pp 97–118, 2014b). The paper argues that all intentionalist accounts face the speaker authority (...) problem, that speaker intentions are just the wrong sorts of things to determine the standards for gradable adjectives in context. The problem comes to light when we look at cases in which speakers have idiosyncratic, false beliefs that cause their proper communicative intentions to come apart from the non-intentional features of context like the question under discussion, facts about the world, practical goals, and prior linguistic discourse.

Discourse dynamics, pragmatics, and indefinites Content Type Journal Article Pages 1-30 DOI 10.1007/s11098-012-9882-y Authors Karen S. Lewis, Department of Philosophy, University of Southern California, Los Angeles, CA, USA Journal Philosophical Studies Online ISSN 1573-0883 Print ISSN 0031-8116.

ABSTRACT The most common answers to metasemantic questions regarding context-sensitive expressions appeal primarily to speakers' intentions. Having rejected intentionalism in Lewis [.” Erkenntnis 85: 1527–1555.], this paper takes a non-intentionalist perspective in answering the metasemantic question: how does a context determine the value of context-sensitive expressions? It focuses on the case of gradable adjectives, i.e. expressions like ‘tall’, ‘expensive’, and ‘rich’, which require a contextually determined standard in the unmarked positive form, as in ‘Pia is tall’. I argue that this (...) standard is determined by a salient comparison class, which, when embedded in the relevant facts, provides input into statistical reasoning which outputs a standard in accordance with conversational domain goals.

This article focuses on foundational issues in dynamic and static semantics, specifically on what is conceptually at stake between the dynamic framework and the truth-conditional framework, and consequently what kinds of evidence support each framework. The article examines two questions. First, it explores the consequences of taking the proposition as central semantic notion as characteristic of static semantics, and argues that this is not as limiting in accounting for discourse dynamics as many think. Specifically, it explores what it means for (...) a static semantics to incorporate the notion of context change potential in a dynamic pragmatics and denies that this conception of static semantics requires that all updates to the context be eliminative and distributive. Second, it argues that the central difference between the two frameworks is whether semantics or pragmatics accounts for dynamics, and explores what this means for the oft-heard claim that dynamic semantics blurs the semantics/pragmatics distinction.

Despite advances in treatments over the last decades, a uniformly reliable and free of side effects therapy of human cancers remains to be achieved. During chromosome replication, a premature halt of two converging DNA replication forks would cause incomplete replication and a cytotoxic chromosome nondisjunction during mitosis. In contrast to normal cells, most cancer cells bear numerous DNA deletions. A homozygous deletion permanently marks a cell and its descendants. Here, we propose an approach to cancer therapy in which a pair (...) of sequence‐specific roadblocks is placed solely at two cancer‐confined deletion sites that are located ahead of two converging replication forks. We describe this method, termed “replication blocks specific for deletions” (RBSD), and another deletions‐based approach as well. RBSD can be expanded by placing pairs of replication roadblocks on several different chromosomes. The resulting simultaneous nondisjunctions of these chromosomes in cancer cells would further increase the cancer‐specific toxicity of RBSD. (shrink)

“Digital footprints” is an attractive, useful, and increasingly popular metaphor for thinking about Big Data. In this essay, I elaborate on this metaphor to highlight three relatively basic fallacies in the way we tend to think about Big Data: first, that they contain information on complete populations, or “N = all”; second, that they contain recordings of naturalistic behavior; and third, that they can be understood devoid of context.

The benefits of belonging for academic performance and persistence have been examined primarily in terms of subjective perceptions of social belonging, but feeling ability belonging, or fit with one’s peers intellectually, is likely also important for academic success. This may particularly be the case in male-dominated fields, where inherent genius and natural talent are viewed as prerequisites for success. We tested the hypothesis that social and ability belonging each explain intentions to persist in physical science, technology, engineering, and math (pSTEM). (...) We further explore whether women experience lower social and ability belonging than men on average in pSTEM, and whether belonging more strongly relates to intentions to persist for women. At three time points throughout a semester, we assessed undergraduate pSTEM majors enrolled in a foundational calculus or physics course. Women reported lower pSTEM ability belonging and self-efficacy than men, but higher identification with pSTEM. End of semester social belonging, ability belonging, and identification predicted intentions to persist in pSTEM, with a stronger relationship between social belonging and intentions to persist in pSTEM for women than men. These findings held after controlling for prior and current academic performance, as well as two conventional psychological predictors of academic success. (shrink)

We investigate what distinguishes social entrepreneurial ecosystems (SEEs) from entrepreneurial ecosystems (EEs) through appreciation of the importance of context—the multiplex of intertwined social, spatial, temporal, historical, cultural, and political influences. Community is incorporated as a key variable and hitherto overlooked dimension of the structure and influence of SEEs. We draw on extant literature and examples of a variety of SEEs to support our propositions and demonstrate why considerations of both context and community are critical to advance understanding of SEEs. We (...) contribute to the study of SEEs by presenting a new conceptual framework and theorizing SEE as an evolving composite of interdependent actors who interact and collaborate across multiple levels to collectively generate positive externalities and drive sustainable solutions to social problems.

This paper examines the causes of pupil mobility and good practice in schools to address mobility issues. Pupil mobility is defined as ?a child joining or leaving school at a point other than the normal age at which children start or finish their education at that school?. The first part draws upon evidence of a survey, which explores the views of headteachers on the nature and causes of pupil mobility in schools and the priority they give to addressing pupil mobility (...) issues in their schools. It examines the cause of mobility in schools in the context of mobile groups. This is followed by the challenges for managing mobility and strategies to address pupil mobility in schools. The second part of the paper outlines successful strategies that minimize the effects of mobility in schools. Evidence is drawn from case?study research and focuses on the school systems, pastoral care and access to learning which combine to support the induction, assessment and monitoring of newly arrived pupils in school and effective use of data for self?evaluation. Examples of flexible curriculum organization, innovative approaches to additional support and effective administrative procedures are drawn upon. Evidence reflects the views of a range of school staff, parents/carers and pupils in the case?study school, as well as the judgements of senior researchers. Policy implications for government and for all concerned with school performance are highlighted, as well as many practical suggestions for raising achievement of mobile pupils. (shrink)

This study aims to examine the key barriers to learning to raise achievement of White British pupils with low?income backgrounds. The main findings suggest that the worryingly low?achievement levels of many White working class pupils have been masked by the middle class success in the English school system and government statistics that fail to distinguish the White British ethnic group by social background. The empirical data confirm that one of the biggest groups of underachievers is the White British working class (...) and their outcomes at each key stage are considerably below those achieved by all other ethnic groups. One of the main reasons for pupil underachievement, identified in the case study schools and focus groups, is parental low aspirations of their children?s education and social deprivation. It is also perpetuated by factors such as low?literacy levels, feelings of marginalisation within the community exacerbated by housing allocation, a lack of community and school engagement, low levels of parental engagement and lack of targeted support to break the cycle of poverty and disadvantage, a legacy of low aspiration that prevents pupils from fulfilling their potential across a range of areas. The study concludes that the main obstacle in raising achievement is the government?s failure to recognise that this group has particular needs that are not being met by the school system. The government needs to recognise that the underachievement of White British working class pupils is not only a problem facing educational services but profoundly a serious challenge. Policy implications and recommendations are discussed in the final section. (shrink)

The Anthropology of Sport and Human Movement represents a collection of work that reveals and explores the often times dramatic relationship of our biology and culture that is inextricably woven into a tapestry of movement patterns. It explores the underpinning of human movement, reflected in play, sport, games and human culture from an evolutionary perspective and contemporary expression of sport and human movement.

ImportancePrevious studies of post-acute COVID-19 syndrome have focused on critical cases with severe disease. However, most cases are mild to moderate in disease severity.ObjectiveWe aimed to examine cognitive outcomes in cases of non-critical, mild-to-moderate COVID-19. Design, Setting, and Participants: In this cross-sectional study, we enrolled 72 adults aged 22 to 65 years in Central Texas who had non-critical, mild-to-moderate COVID-19 infection between 13 January 2021 and 20 April 2021.Main Outcomes and MeasuresWe remotely administered cognitive-behavioral testing to determine the frequency of (...) cognitive impairment and examine demographic, clinical, and psychosocial contributors to impairment.ResultsThe frequency of objective cognitive impairment was 40%. The largest number of participants showed impairment on a measure of executive functioning. Attention and processing speed was more impaired in males. Males endorsed lower adherence to social distancing guidelines, which was in turn associated with cognitive impairment across participants. Younger age was correlated with impairment but was also associated with racial/ethnic minority status and increased psychological symptoms. Moderate COVID-19 severity was associated with attention/processing speed impairment, increased pain, and higher number of COVID-19 symptoms.Conclusion and RelevanceMild or moderate COVID-19 infection may be associated with cognitive impairments, especially in the domain of executive functioning. A subgroup of younger individuals may be more vulnerable to cognitive and psychosocial effects of COVID-19.HighlightsQuestion: How frequent is cognitive impairment among non-critical, mild-to-moderate COVID-19 survivors?FindingsIn this cross-sectional study of 72 adults, 40% demonstrated cognitive impairment, particularly in executive function.MeaningNeurologic sequelae, such as cognitive impairment, may be common following COVID-19 infection.

The hypothesis that play behavior is more prevalent in larger-brained animals has recently been challenged. It may be, for example, that only certain brain structures are related to play. Here, we analyze social play behavior with regards to the cerebellum: a structure strongly implicated in motor-development, and possibly also in cognitive skills. We present an evolutionary analysis of social play and the cerebellum, using a phylogenetic comparative method. Social play frequency and relative cerebellum size are positively correlated. Hence, there appears (...) to be a link between the evolutionary elaboration of social play and the cerebellum. (shrink)

Studies of education and careers in science, technology, engineering, and math commonly use a pipeline metaphor to conceptualize forward movement and persistence. However, the “STEM pipeline” carries implicit assumptions regarding length, contents, and perceived purpose. Using the National Survey of College Graduates, we empirically measure each of these dimensions. First, we show that a majority of STEM workers report skills training throughout their careers, suggesting no clear demarcation between education and work. Second, we show that using on-the-job expertise requirements paints (...) a very different portrait of the STEM workforce—and persistence in it. Third, we show that STEM-educated workers are well-prepared for but dissatisfied with non-STEM jobs, complicating our understanding of leaving. Collectively, these results recommend expanded conceptions of STEM education and careers and contribute to studies of science and engineering workforce transitions and diversity. (shrink)
