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.

Macroeconomics: An Introduction, provides a lucid and novel introduction to macroeconomic issues. It introduces the reader to an alternative approach of understanding macroeconomics, which is inspired by the works of Adam Smith, David Ricardo, Karl Marx, John Maynard Keynes, and Piero Sraffa. It also presents the reader with a critical account of mainstream marginalist macroeconomics. The book begins with a brief history of economic theories and then takes the reader through three different ways of conceptualizing the macroeconomy. Subsequently, the theories (...) of money and interest rates, output and employment levels, and economic growth are discussed. The book ends by providing a policy template for addressing the macroeconomic concerns of unemployment and inflation. The conceptual discussion in Macroeconomics is situated within the context of the Indian economy. Besides using publicly available data, the contextual description is instantiated using excerpts from works of fiction by Indian authors. (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)

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)

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 (GABA) and perceptual suppression in persons with amblyopia (PWA), we employed magnetic resonance spectroscopy (MRS) to quantify GABA levels in both PWA and normally-sighted persons (NSP). 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 (the difference in visual acuity between the amblyopic and non-amblyopic eyes) 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)

This book is dedicated to V.A. Yankov’s seminal contributions to the theory of propositional logics. His papers, published in the 1960s, are highly cited even today. The Yankov characteristic formulas have become a very useful tool in propositional, modal and algebraic logic. The papers contributed to this book provide the new results on different generalizations and applications of characteristic formulas in propositional, modal and algebraic logics. In particular, an exposition of Yankov’s results and their applications in algebraic logic, the theory (...) of admissible rules and refutation systems is included in the book. In addition, the reader can find the studies on splitting and join-splitting in intermediate propositional logics that are based on Yankov-type formulas which are closely related to canonical formulas, and the study of properties of predicate extensions of non-classical propositional logics. The book also contains an exposition of Yankov’s revolutionary approach to constructive proof theory. The editors also include Yankov’s contributions to history and philosophy of mathematics and foundations of mathematics, as well as an examination of his original interpretation of history of Greek philosophy and mathematics.

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)

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.

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)

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 1970, Jacque Monod, a Nobel Laureate and a founding father of molecular biology, wrote a short celebrated book entitled Chance and Necessity.

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.

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)

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.

This study tries to check the degree of basic human values among management professionals in India with considerable cultural and linguistic differences and how it varies across the different demographic influences. We have checked the impact of demographic variables like gender, age, education, type of organisation, place of residence, and work experience on basic human values. Hypotheses testing were conducted using MANOVA. It was inferred that the perception regarding the degree of basic human values differs among different management professionals based (...) on their age, gender, education, type of organisation, and place of residence. Surprisingly, the work experience of the person does not have a significant influence on basic human values. Consequently, we imply that the demographics of an individual carve their basic human values. The findings and inferences of the proposed study will be of great importance to policymakers and recruiting managers to fetch the right candidate. (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 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.

Advertising by health care institutions has increased steadily in recent years. While direct-to-consumer prescription drug advertising is subject to unique oversight by the Federal Drug Administration, advertisements for health care services are regulated by the Federal Trade Commission and treated no differently from advertisements for consumer goods. In this article, we argue that decisions about pursuing health care services are distinguished by informational asymmetries, high stakes, and patient vulnerabilities, grounding fiduciary responsibilities on the part of health care providers and health (...) care institutions. Using examples, we illustrate how common advertising techniques may mislead patients and compromise fiduciary relationships, thereby posing ethical risks to patients, providers, health care institutions, and society. We conclude by proposing that these risks justify new standards for advertising when considered as part of the moral obligation of health care institutions and suggest that mechanisms currently in place to regulate advertising for prescription pharmaceuticals should be applied to advertising for health care services more broadly.

Adaptive mutation is defined as a process that, during nonlethal selections, produces mutations that relieve the selective pressure whether or not other, nonselected mutations are also produced. Examples of adaptive mutation or related phenomena have been reported in bacteria and yeast but not yet outside of microorganisms. A decade of research on adaptive mutation has revealed mechanisms that may increase mutation rates under adverse conditions. This article focuses on mechanisms that produce adaptive mutations in one strain of Escherichia coli, FC40. (...) These mechanisms include recombination-induced DNA replication, the placement of genes on a conjugal plasmid, and a transient mutator state. The implications of these various phenomena for adaptive evolution in microorganisms are discussed. BioEssays 22:1067–1074, 2000. © 2000 John Wiley & Sons, Inc. (shrink)

The present study examines cross-cultural differences in people’s concept of lying with regard to the question of whether lying requires an agent to _say_ something they believe to be false. While prominent philosophical views maintain that lying entails that a person explicitly expresses a believed-false claim, recent research suggests that people’s concept of lying might also include certain kinds of deception that are communicated more indirectly. An important drawback of previous empirical work on this topic is that only few studies (...) have investigated people’s concept of lying in non-Western samples. In the present study, we compare people’s intuitions about lying with indirect deceptions (i.e., presuppositions, conversational implicatures, and non-verbal actions) in a sample of _N_ = 255 participants from Russia and _N_ = 300 participants from the United Kingdom. Our findings show a strong degree of similarity between lie ratings of participants from Russia and the United Kingdom, with both samples holding it possible for agents to lie with deceptive statements and actions that do not involve the agent _saying_ something they believe to be false.

The discovery, more than 60 years ago, of a mutant mouse with a short tail led to the birth of the new field of developmental genetics. Over the years since, numerous investigators have probed the biology of the original short‐tail mutation at the T locus, as well the naturally‐occurring t haplotypes that were uncovered as a result of their interaction with this mutation. Although the T locus ranks among the best characterized developmental loci in the mouse, it was not among (...) the first to be cloned. This situation has now been rectified with two recent reports from Herrmann, Lehrach and their colleagues. While the T locus is expressed uniquely in the embryonic tissues predicted from the mutant phenotype, the gene itself, as well as the predicted amino acid sequence of the T product, show no strong homology to any known sequence. For the moment, at least, the mystery behind the function of the T locus still awaits definitive resolution. (shrink)

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.

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.

Whilst previous observational studies have linked negative thought processes such as an external locus of control and holding negative cognitive styles with depression, the directionality of these associations and the potential role that these factors play in the transition to adulthood and parenthood has not yet been investigated. This study examined the association between locus of control and negative cognitive styles in adolescence and probable depression in young adulthood and whether parenthood moderated these associations. Using a UK prospective population-based birth (...) cohort study: the Avon Longitudinal Study of Parents and Children, we examined the association between external locus of control and negative cognitive styles in adolescence with odds of depression in 4,301 young adults using logistic regression models unadjusted and adjusted for potential confounding factors. Interaction terms were employed to examine whether parenthood moderated these associations. Over 20% of young adults in our sample were at or above the clinical threshold indicating probable depression. For each standard deviation increase in external locus of control in adolescence, there was a 19% higher odds of having probable depression in young adulthood, after adjusting for various confounding factors including baseline mood and different demographic and life events variables. Similarly, for each SD increase in negative cognitive styles in adolescence, there was a 29% higher odds of having probable depression in the adjusted model. We found little evidence that parenthood status moderated the relationship between external locus of control or negative cognitive styles in adolescence and probable depression following adjustment for confounding factors. Effect estimates were comparable when performed in the complete case dataset. These findings suggest that having an external locus of control and holding negative cognitive styles in mid- to late adolescence is associated with an increased likelihood of probable depression in young adulthood.
