The proposal by Clarke and Beck offers a new explanation for the association between the approximate number system and math. Previous explanations have largely relied on developmental arguments, an underspecified notion of the ANS as an “error detection mechanism,” or affective factors. The proposal that the ANS represents rational numbers suggests that it may directly support a broader range of math skills.
Continuing work begun in [10], we utilize a notion of forcing for which the generic objects are structures and which allows us to determine whether these “generic” structures compute certain sets and enumerations. The forcing conditions are bounded complexity types which are consistent with a given theory and are elements of a given Scott set. These generic structures will “represent” this given Scott set, in the sense that the structure has a certain weak saturation property with respect to bounded complexity (...) types in the Scott set. For example, if ? is a nonstandard model of PA, then ? represents the Scott set ? = n∈ω | ?⊧“the nth prime divides a” | a∈?.The notion of forcing yields two main results. The first characterizes the sets of natural numbers computable in all models of a given theory representing a given Scott set. We show that the characteristic function of such a set must be enumeration reducible to a complete existential type which is consistent with the given theory and is an element of the given Scott set.The second provides a sufficient condition for the existence of a structure ? such that ? represents a countable jump ideal and ? does not compute an enumeration of a given family of sets ?. This second result is of particular interest when the family of sets which cannot be enumerated is ? = Rep[Th(?)]. Under this additional assumption, the second result generalizes a result on TA [6] and on certain other completions of PA [10]. For example, we show that there also exist models of completions of ZF from which one cannot enumerate the family of sets represented by the theory. (shrink)
We examine the relationship between two different notions of a structure being Scott set saturated and identify sufficient conditions which guarantee that a structure is uniquely Scott set saturated. We also consider theories representing Scott sets; in particular, we identify a sufficient condition on a theory T so that for any given countable Scott set there exists a completion of T that is saturated with respect to the given Scott set. These results extend Scott's characterization of countable Scott sets via (...) models and completions of Peano arithmetic. (shrink)
Recent arbitration and human rights boards of inquiry cases involving discrimination against pregnant employees are reviewed. A comparison is made between remedies available under each procedure. It is suggested that the human resource managers review their policies and procedures relevant to this issue to ensure that they do not have the effect or intent of discriminating against pregnant employees.
In amblyopia, abnormal visual experience during development leads to an enduring loss of visual acuity in adulthood. Physiological studies in animal models suggest that intracortical GABAergic inhibition may mediate visual deficits in amblyopia. To better understand the relationship between visual cortical γ-aminobutyric acid and perceptual suppression in persons with amblyopia, we employed magnetic resonance spectroscopy to quantify GABA levels in both PWA and normally-sighted persons. In the same individuals, we obtained psychophysical measures of perceptual suppression for a variety of ocular (...) configurations. In PWA, we found a robust negative correlation between the depth of amblyopia and GABA concentration that was specific to visual cortex and was not observed in a sensorimotor cortical control region. Moreover, lower levels of visual cortical GABA were associated with weaker perceptual suppression of the fellow eye by the amblyopic eye and stronger suppression of the amblyopic eye by the fellow eye. Taken together, our findings provide evidence that intracortical GABAergic inhibition is an important component of the pathology of human amblyopia and suggest possible therapeutic interventions to restore vision in the amblyopic eye through enhancement of visual cortical GABAergic signaling in PWA.

The current paper proposes the Dysexecutive Luck hypothesis; that beliefs in being unlucky are associated with deficits in executive functioning. Four studies suggest initial support for the Dysexecutive Luck hypothesis via four aspects of executive functioning. Study 1 established that self-reports of dysexecutive symptoms predicted unique variance in beliefs in being unlucky after controlling for a number of other variables previously reported to be related to beliefs around luck. Studies 2 to 4 demonstrated support for the Dysexecutive Luck hypothesis via (...) assessment of executive functioning via: two fundamental executive functions , emotional processes related to executive functioning as described by the Somatic Marker hypothesis, and higher executive functions as accessed via divergent thinking. The findings suggest that individuals’ beliefs in being unlucky are accompanied by a range of deficits in executive functioning. (shrink)
Across a variety of situations, people strongly condemn plagiarizers who steal credit for ideas, even when the theft in question does not appear to harm anyone. Why would people react negatively to relatively harmless acts of plagiarism? In six experiments, we predict and find that these negative reactions are driven by people's aversion toward agents who attempt to falsely improve their reputations. In Studies 1–3, participants condemn plagiarism cases that they agree are harmless. This effect is mediated by the extent (...) to which participants perceive the plagiarizer to have falsely benefitted from plagiarizing. In Studies 4–5, we demonstrate that this effect is not explained solely by participants’ negative response to lies or violations of permission. In Study 6, participants condemn a plagiarism case in which the idea's original author actually benefits, providing the strongest evidence that people condemn plagiarism for reasons beyond perceived harm. We discuss how this work connects to broader questions of intellectual property and impression management. (shrink)
Book synopsis: Our mental lives are entwined with the world. There are worldly things that we have beliefs about and things in the world we desire to have happen. We find some things fearsome and others likable. The puzzle of intentionality — how it is that our minds make contact with the world — is one of the oldest and most vexed issues facing philosophers. Many contemporary philosophers and cognitive scientists have been attracted to the idea that our minds represent (...) the world. This book explores an important assumption about representation, namely, that when we represent things in the world, we represent them as having properties, and in this way our representations have "propositional" structure. The contributors examine what the commitment to propositionalism amounts to; illuminate why one might find the thesis attractive ; and consider ways in which one might depart from propositionalism. The hope is that this will lead towards a more complete understanding of how the mind and world are connected. (shrink)
The virtue of mercy is widely admired, but is now marginalized in contemporary public life. Yet for centuries it held a secure place in western public discourse without implying a necessary contradiction with justice. Alex Tuckness and John M. Parrish ask how and why this changed. Examining Christian and non-Christian ancient traditions, along with Kantian and utilitarian strains of thought, they offer a persuasive account of how our perception of mercy has been transformed by Enlightenment conceptions of impartiality and (...) equality that place justice and mercy in tension. Understanding the logic of this decline, they argue, will make it possible to promote and defend a more robust role for mercy in public life. Their study ranges from Homer to the late Enlightenment and from ancient tragedies to medieval theologies to contemporary philosophical texts, and will be valuable to readers in political philosophy, political theory, and the philosophy of law.

In face-to-face interaction, speakers make multimodal contributions that exploit both the linguistic resources of spoken language and the visual and spatial affordances of gesture. In this paper, we argue that, in formulating and understanding such multimodal contributions, interlocutors apply the same principles of coherence that characterize the interpretation of natural language discourse. In particular, we use a close analysis of a series of naturally-occurring embodied discourses to argue for two key generalizations. First, communicators and their audiences draw on coherence relations (...) to establish interpretive connections between successive gestures and between gestures and speech. Second, coherence relations facilitate meaning-making by resolving the underspecified meaning of each communicative act through constrained inference over entities, propositions, and spatial frames made salient in the prior discourse. Our approach to gesture interpretation improves on previous work in better accounting for its flexibility, in capturing its constraints, and in laying the groundwork for formal and computational models. At the same time, it shows that gesture provides an important source of evidence to sharpen the theory of coherence relations and contextual resolution. (shrink)
In this paper, we investigate the representation of negated sentences in Minimal Recursion Semantics (Copestake, Flickinger, Pollard, & Sag, 2005). We begin with its treatment in the English Resource Grammar (Flickinger, 2000, 2011), a broad-coverage implemented HPSG (Pollard & Sag, 1994), and argue that it is largely a suitable representation for English, despite possible objections. We then explore whether it is suitable for typologically different languages: namely, those that express sentential negation via inflection on the verb, particularly Turkish and Inuktitut. (...) We find that the interaction between negation and intersective modifiers requires a change to the way in which (at least) one of them contributes to semantic composition, and we argue for adapting the analysis of intersective modifiers.

Questions concerning the moral status of embryos, the validity of new technologies for human reproduction, ownership of one's own genes, gene patenting, privacy and discrimination have all been raised and debated. Although debate is healthy, it is only useful if all participants understand the fundamental biological principles underlying human life, human genes and human parenthood. Many people believe that science can play no role in determining when human life begins. I argue that this false assumption is based on a failure (...) to separate different contradictory meanings of the term ‘human life’. In actuality, science has provided great insight into when and how human life and human beings come into existence. I argue as well that, contrary to our intuitive feelings, there is no physical connection between any father and his son; shared genes represent shared information and nothing more. Nevertheless, the feeling of a physical connection between parent and child is very real and instinctive, no matter how false it may be. These new understandings have profound ramifications for the way we treat issues surrounding human reproduction, including both abortion and assisted reproductive technologies. (shrink)
The precarious rights of senior citizens, especially those who are highly educated and who are expected to counsel and guide the younger generations, has stimulated the creation internationally of advocacy associations and opinion leader groups. The strength of these groups, however, varies from country to country. In some countries, they are supported and are the focus of intense interest; in others, they are practically ignored. For this is reason we believe that the creation of a network of all these associations (...) is essential. The proposed network would act as a support for the already-existing policies of the United Nations’ High Commission for Human Rights, of independent experts, and of the Global Alliance for the Rights of Older People. All three have long ago recommended the creation of a recognized instrument for uniting presently scattered efforts. The proposed network, therefore, will seek to promote the international exchange of relevant expertise, and it will reinforce the commitments and actions that single countries are currently taking to meet these objectives. For example, informative public events can be organised to promote particular support initiatives and to provide an opportunity for new members of the network to be presented. The network will promote health for senior citizens, disease prevention, senior mobility, safe free time for seniors, alimentary education, protection against new risks and dangers, as well as equity in the services necessary for seniors to adopt new information and communication technologies. In the case of retired academic members, the network will promote equality with respect to continuing use of digital technologies (particularly email), continuing access to research libraries, and the guaranteed ability for seniors to fund their own research programs and to deliver free seminars.

This essay comments on the articles by Loretta M. Kopelman and Anita Silvers. It extends their analyses and concludes that consistency and the total absence of conflict may be unavailable when one interprets and applies the Americans with Disabilities Act.
Academic misconduct is widespread in schools, colleges, and universities and it appears to be an international phenomenon that also spills over into the workplace. To this end, while a great deal of research has investigated various individual components such as, demographic, personality and situational factors that contribute to cheating, research has yet to examine why students help others cheat and which students are being asked to help others cheat. In this study, we investigated if the closeness of the relationship to (...) the individual requesting help in cheating to the individual being asked to help cheat, influenced the decision to help cheat. We also investigated if past cheating behavior predicted how an individual would respond to requests to cheat. Additionally, we sought to answer the following questions; whether minor cheating is more prevalent than serious cheating, what personality factors predict helping others cheat, who is helped, and how people rationalize helping others cheat. Results indicate minor cheating to be more prevalent, prudent personalities are less likely to have cheated or to help others cheat, individuals are more likely to help friends cheat than to help strangers, and past cheating behaviors is indicative of helping others to cheat. Implications for research and practice are discussed. (shrink)
We analyse the tensions in a hybrid collaboration and how these are mitigated using boundary-spanning community impact, leading to compatibility between distinctive institutional logics. Our qualitative longitudinal study undertaken during 2011–2016 involved reviewing literature and archival data, key informant interviews, workshop and focus groups. We analysed common themes within the data, relating to our two research questions concerning how and why hybrids collaborate, and how resulting tensions are mitigated. The findings suggest a viable model of service delivery termed hybridized collaboration (...) in which the inherent tensions from different institutional logics do not prevent success. Paradoxically, multiple logics are a basis for the partnership’s existence, but the ability to achieve different and occasionally conflicting aims simultaneously can be difficult, resulting in tensions. We offer two novel insights. First, we highlight how social enterprise hybrids collaborate locally and in multi-organizational relationships. We found that the initial opportunity to collaborate was catalysed by the existence of shared objectives. Pre-existing relationships between organizations, and the existence of synergistic capabilities also influence the choice of partners. Secondly, we identify how tensions arise, and are mitigated via several factors including the pre-existing relationships, allowing for regular “spaces of negotiation” between collaborators, the shared social mission, community social impact, the resulting public relations, and shared resources and knowledge.

On Sunday morning, 23 February 1997, the world awoke to a technological advance that shook the foundations of biology and philosophy. On that day, we were introduced to Dolly, a 6-month-old lamb that had been cloned directly from a single cell taken from the breast tissue of an adult donor. Perhaps more astonished by this accomplishment than any of their neighbors were the scientists who actually worked in the field of mammalian genetics and embryology. Outside the lab where the cloning (...) had actually taken place, most of us thought it could never happen. Oh, we would say that perhaps at some point in the distant future, cloning might become feasible through the use of sophisticated biotechnologies far beyond those available to us now. But what many of us really believed, deep in our hearts, was that this was one biological feat we could never master. New lifemust have its origins in an embryo formed through the merger of gametes from a mother and father. It was impossible, we thought, for a cell from an adult mammal to become reprogrammed, to start all over again, to generate another entire animal or person in the image of the one born earlier.

In this paper I will discuss three areas in which advances in human reproductive technology could occur, their uses and abuses, and their effects on society. First is the potential to drastically increase the success rate and availability of in vitro fertilization and embryo freezing. Second is the ability to perform biopsies on embryos prior to the onset of pregnancy. Finally, I will consider the adding or altering of genes in embryos, commonly referred to as genetic engineering.As new reproductive technologies (...) pass from experimental models into the potential for medical utilization, I believe that it will be important for lawmakers everywhere to avoid the impulse to outlaw procedures that a society believes to be unnatural at a first glance. Rather, I would hope that they can respond thoughtfully with legislation that serves two purposes — to protect the rights of couples to overcome infertility or to reduce the risk of genetic disease in their children-to-be, and more importantly, to protect children-to-be from the abuses that could result from some of the practices that I will discuss.

Patient-funded trials are gaining traction as a means of accelerating clinical translation. However, such trials sidestep mechanisms that promote rigor, relevance, efficiency, and fairness. We recommend that funding bodies or research institutions establish mechanisms for merit review of patient-funded trials, and we offer some basic criteria for evaluating PFT protocols.
The Patient's Charter has been in effect for nearly five years. This article considers the purpose and value of the document through a comparison with the New Jersey Patient Bill of Rights. Patient rights statements have been posted in American hospitals for more than twenty years. However, the New Jersey document and the patient rights programme it established seven years ago, have proven to be economically effective, successful in their representation of patients and enforceable, due to the adoption of state (...) legislation and regulation to oversee the process. Several examples of how the programme works are included in the comparison, with a similar review of The Patient's Charter. In the comparison the author argues that for the programme to succeed as it has done in New Jersey, the government will need to develop legislative backing to ensure enforcement, and an efficient system for monitoring compliance. The programme will need to become credible in the eyes of the health service user. The author suggests this may be best achieved by developing an efficient, accessible and user-friendly means of redress, should the patient consider his or her rights have been violated. A "mish-mash" of quality assurance standards and levels of care which patients can "expect" from the health service providers only serves to distract the health service user from the government's failure to commit the resources that would empower the patients rights portion of The Patient's Charter.

Lying is an important moral phenomenon that most people are affected by on a daily basis—be it in personal relationships, in political debates, or in the form of fake news. Nevertheless, surprisingly little is known about what actually constitutes a lie. According to the traditional definition of lying, a person lies if they explicitly express something they believe to be false. Consequently, it is often assumed that people cannot lie by more indirectly communicating believed‐false claims, for instance by merely conversationally (...) implicating them. In this paper, we subject this claim to an empirical test. In a preregistered study of 300 participants, we investigate how people judge cases of implicit deceptions that would usually be excluded by the traditional definition of lying (i.e., conversational implicatures, presuppositions, and nonverbal actions). Our results show that people do in fact consider it possible to lie by indirect means, suggesting that people have a broader concept of lying than is usually assumed. Moreover, our findings indicate that lie judgments are closely tied to the extent to which agents are perceived as having committed themselves to the believed‐false claims they have communicated. We discuss the implications of our results for the traditional definition of lying and propose a new commitment‐based definition of lying that can account for the findings of our experiment.
