The successful demonstration that antiretroviral (ARV) drugs can be used in diverse ways to reduce HIV acquisition or transmission risks – either taken as pre-exposure prophylaxis (PrEP) by those who are uninfected or as early treatment for prevention (T4P) by those living with HIV – expands the armamentarium of existing HIV prevention tools. These findings have implications for the design of future HIV prevention research trials. With the advent of multiple effective HIV prevention tools, discussions about the ethics and the (...) feasibility of future HIV prevention trial designs have intensified. This article outlines arguments concerning the inclusion of newly established ARV-based HIV prevention interventions as standard of prevention in HIV prevention trials from multiple perspectives. Ultimately, there is a clear need to incorporate stakeholders in a robust discussion to determine the appropriate trial design for each study population. (shrink)

Afferent feedback can appreciably alter the pharyngeal phase of swallow. In order to measure the stability of the swallow motor pattern during several types of alterations in afferent feedback, we assessed swallow during a conventional water challenge in four anesthetized cats, and compared that to swallows induced by fixed (20 Hz) and stochastic (1-20Hz) electrical stimulation applied to the superior laryngeal nerve. The swallow motor patterns were evaluated by electromyographic activity (EMG) of eight muscles, based on their functional significance: laryngeal (...) elevators (mylohyoid, geniohyoid, and thyrohyoid); laryngeal adductor (thyroarytenoid); inferior pharyngeal constrictor (thyropharyngeus); upper esophageal sphincter (cricopharyngeus); and inspiratory activity (parasternal and costal diaphragm). Both the fixed and stochastic electrical stimulation paradigms increased activity of the laryngeal elevators, produced short-term facilitation evidenced by increasing swallow durations over the stimulus period, and conversely inhibited swallow-related diaphragm activity. Both the fixed and stochastic stimulus conditions also increased specific EMG amplitudes, which never occurred with the water challenges. Stochastic stimulation increased swallow excitability, as measured by an increase in the number of swallows produced. Consistent with our previous results, changes in the swallow motor pattern for pairs of muscles were only sometimes correlated with each other. We conclude that alterations in afferent feedback produced particular variations of the swallow motor pattern. We hypothesize that specific SLN feedback might modulate the swallow central pattern generator during aberrant feeding conditions (food/liquid entering the airway), which may protect the airway and serve as potentially important clinical diagnostic indicators.

Speech acts are a staple of everyday communicative life, but only became a topic of sustained investigation, at least in the English-speaking world, in the middle of the Twentieth Century.[1] Since that time “speech act theory” has been influential not only within philosophy, but also in linguistics, psychology, legal theory, artificial intelligence, literary theory and many other scholarly disciplines.[2] Recognition of the importance of speech acts has illuminated the ability of language to do other things than describe reality. In the (...) process the boundaries among the philosophy of language, the philosophy of action, the philosophy of mind and even ethics have become less sharp. In addition, an appreciation of speech acts has helped lay bare an implicit normative structure within linguistic practice, including even that part of this practice concerned with describing reality. Much recent research aims at an accurate characterization of this normative structure underlying linguistic practice. (shrink)

The `fact' of pluralism in science is nosurprise. Yet, if science is representing andexplaining the structure of the oneworld, why is there such a diversity ofrepresentations and explanations in somedomains? In this paper I consider severalphilosophical accounts of scientific pluralismthat explain the persistence of bothcompetitive and compatible alternatives. PaulSherman's `Levels of Analysis' account suggeststhat in biology competition betweenexplanations can be partitioned by the type ofquestion being investigated. I argue that thisaccount does not locate competition andcompatibility correctly. I then defend anintegrative (...) model for understanding pluralism. This view is based on taking seriously both thecomplexity and contingency of biologicalorganization and the idealized character ofbiological models. On this view, explanationbecomes, among other things, the location forthe integration of diverse models. I explicatemy argument by an analysis of explanations ofdivision of labor in social insects.

On some formulations of Direct Reference the semantic value, relative to a context of utterance, of a rigid singular term is just its referent. In response to the apparent possibility of a difference in truth value of two sentences just alike save for containing distinct but coreferential rigid singular terms, some proponents of Direct Reference have held that any two such sentences differ only pragmatically. Some have also held, more specifically, that two such sentences differ by conveying distinct conversational implicata, (...) and that a conflation of implicatum with semantic content leads speakers to judge such sentences capable of differing in truth value. It is argued here that this latter defense of Direct Reference employs false explanans, on the ground that speakers conflate semantic content with implicatum only in quite special cases, and we have independent grounds for thinking that sentences reporting speech acts and attitudes are not cases of this sort.

Some theories of personal identity allow some variation in what it takes for a person to survive from context to context; and sometimes this is determined by the desires of person-stages or the practices of communities.This leads to problems for decision making in contexts where what is chosen will affect personal identity.‘Temporal Phase Pluralism’ solves such problems by allowing that there can be a plurality of persons constituted by a sequence of person stages. This illuminates difficult decision making problems when (...) persons have to choose between different life-altering choices. (shrink)

It has been claimed that ceteris paribus laws, rather than strict laws are the proper aim of the special sciences. This is so because the causal regularities found in these domains are exception-ridden, being contingent on the presence of the appropriate conditions and the absence of interfering factors. I argue that the ceteris paribus strategy obscures rather than illuminates the important similarities and differences between representations of causal regularities in the exact and inexact sciences. In particular, a detailed account of (...) the types and degrees of contingency found in the domain of biology permits a more adequate understanding of the relations among the sciences. (shrink)

In this paper I discuss recent debates concerning etiological theories of functions. I defend an etiological theory against two criticisms, namely the ability to account for malfunction, and the problem of structural doubles. I then consider the arguments provided by Bigelow and Pargetter (1987) for a more forward looking account of functions as propensities or dispositions. I argue that their approach fails to address the explanatory problematic for which etiological theories were developed.

In interpretations of the "Transcendental Aesthetic" section of the first Critique, there is a widespread tendency to present Kant as establishing that the representation of space is a condition for individuating or distinguishing objects, and to claim that it is on this basis that Kant establishes the apriority of this representation. The aim of this paper is to criticize this way of interpreting the "Aesthetic," and to defend an alternative interpretation. On this alternative, questions about the formation of the representation (...) of space figure more centrally, and the anti-Leibnizian character of Kant 's argument can be properly appreciated.

How can the reference of theoretical terms be stable over changes of theory? I defend an approach to this that does not depend on substantive metasemantic theories of reference. It relies on the idea that in contexts of use, terms may play a role in a theory that in turn points to a further (possibly unknown) theory. Empirical claims are claims about the nature of the further theories, and the falsification of these further theories is understood not as showing that (...) a term in the original theory fails to refer, but rather that a scientific hypothesis encapsulated by the further theory is mistaken.

Know Thyself: The Value and Limits of Self-Knowledge takes the reader on tour of the nature, value, and limits of self-knowledge. Mitchell S. Green calls on classical sources like Plato and Descartes, 20th-century thinkers like Freud, recent developments in neuroscience and experimental psychology, and even Buddhist philosophy to explore topics at the heart of who we are. The result is an unvarnished look at both the achievements and drawbacks of the many attempts to better know one's own self. Key (...) topics in this volume include: Knowledge - what it means to know, the link between wisdom and knowledge, and the value of living an "examined life" Personal identity - questions of dualism, bodily continuity, and personhood The unconscious - including the kind posited by psychoanalysis as well as the form proposed by recent research on the so-called adaptive unconscious Free will - if we have it, and the recent arguments from neuroscience challenging it Self-misleading - the ways we willfully deceive ourselves, and how this relates to empathy, peer disagreement, implicit bias, and intellectual humility Experimental psychology - considerations on the automaticity of emotion and other cognitive processes, and how they shape us This book is designed to be used in conjunction with the free 'Know Thyself' MOOC created through collaboration of the University of Connecticut's Project on Humility and Conviction in Public Life, and the University of Edinburgh's Eidyn research centre, and hosted on the Coursera platform. The book is also suitable as a text for interdisciplinary courses in the philosophy of mind or self-knowledge, and is highly recommended for anyone looking for a short overview of this fascinating topic.

According to many forms of Externalism now popular in the Philosophy of Mind, the contents of our thoughts depend in part upon our physical or social milieu.1 These forms of Externalism leave unchallenged the thesis that the ~non-factive! attitudes we bear towards these contents are independent of physical or social milieu. This paper challenges that thesis. It is argued here that publicly forwarding a content as a supposition for the sake of argument is, under conditions not themselves guaranteeing the existence (...) of that state, sufficient for occupancy of the intentional state of supposing that content. Because a saying may literally create an intentional state, whether one is in such a state does not depend solely upon how things are within one’s skin. Rather, even leaving content fixed, the attitude borne toward that content depends in part upon what norms are in force in one’s milieu. (shrink)

This study empirically examines the association between certain director characteristics and the extent of voluntary audit committee disclosure in annual reports. Results suggest that Singapore's publicly traded firms are more likely to voluntarily disclose audit committee related information as: the number of board members increases; different individuals occupy the roles of CEO and board chairperson; and the proportion of independent directors serving on the board increases. Findings, however, fail to show any association between the amount of voluntary audit committee disclosure (...) and the percentage of executive directors' ownership. Documented findings are of interest and benefit to various parties including regulators, corporate governance reformists, and corporate management. For instance, findings imply that a positive by-product of implementing major corporate governance reforms currently championed by corporate governance reformists will be an increase in audit committee disclosures. As a result, there will be less pressure on regulators to develop, introduce, and enforce mandatory audit committee disclosures that may be potentially intrusive to a firm's management. (shrink)

We explore the interaction between oculomotor control and language comprehension on the sentence level using two well-tested computational accounts of parsing difficulty. Previous work (Boston, Hale, Vasishth, & Kliegl, 2011) has shown that surprisal (Hale, 2001; Levy, 2008) and cue-based memory retrieval (Lewis & Vasishth, 2005) are significant and complementary predictors of reading time in an eyetracking corpus. It remains an open question how the sentence processor interacts with oculomotor control. Using a simple linking hypothesis proposed in Reichle, Warren, (...) and McConnell (2009), we integrated both measures with the eye movement model EMMA (Salvucci, 2001) inside the cognitive architecture ACT-R (Anderson et al., 2004). We built a reading model that could initiate short “Time Out regressions” (Mitchell, Shen, Green, & Hodgson, 2008) that compensate for slow postlexical processing. This simple interaction enabled the model to predict the re-reading of words based on parsing difficulty. The model was evaluated in different configurations on the prediction of frequency effects on the Potsdam Sentence Corpus. The extension of EMMA with postlexical processing improved its predictions and reproduced re-reading rates and durations with a reasonable fit to the data. This demonstration, based on simple and independently motivated assumptions, serves as a foundational step toward a precise investigation of the interaction between high-level language processing and eye movement control.

In articles such as “Speech Acts without Propositions?” (2006), Marina Sbisà advocates a “strong” conception of speech acts as means by which speakers modify their own and others’ deontic statuses, including their rights, obligations, and commitments. On this basis Sbisà challenges an influential approach to speech acts as typically if not universally possessing propositional contents. Sbisà argues that such an approach leads to viewing speech acts as primarily aimed at communicating propositional attitudes rather than carrying out socially and normatively significant (...) action. For this reason she advocates eschewing propositions from speech act theory’s conceptual toolkit; she also proposes a liberalization of the distinction between illocutionary force and semantic content, which are widely thought to be mutually exclusive. In this chapter we examine Sbisà’s reasoning and argue that while it does justify denying propositional attitudes a central role in communication, it does not justify dispensing with propositions or other contents in our theorizing about speech acts. In addition, we endorse Sbisà’s proposal for liberalizing the force/content distinction, and show a variety of ways in which force indicators may also possess semantic content. (shrink)

In Belief and the Will, van Fraassen employed a diachronic Dutch Book argument to support a counterintuitive principle called Reflection. There and subsequently van Fraassen has put forth Reflection as a linchpin for his views in epistemology and the philosophy of science, and for the voluntarism (first-person reports of subjective probability are undertakings of commitments) that he espouses as an alternative to descriptivism (first-person reports of subjective probability are merely self-descriptions). Christensen and others have attacked Reflection, taking it to have (...) unpalatable consequences. We prescind from the question of the cogency of diachronic Dutch Book arguments, and focus on Reflection's proper interpretation. We argue that Reflection is not as counterintuitive as it appears — that once interpreted properly the status of the counterexamples given by Christensen and others is left open. We show also that descriptivism can make sense of Reflection, while voluntarism is not especially well suited to do so. (shrink)

Although Longino and Solomon are interested in what social conditions will produce better science, neither philosopher has provided a sufficient analysis of the social character of science. For instance, neither considers the social character of discovery as well as that of justification, or that an individual scientist’s social status and social relations may be important for understanding her role in both processes. The contributors to Schmitt’s volume are interested in whether the terms that refer to social entities can be reduced (...) to or eliminated in favor of terms referring to individuals. Their analyses, which proceed largely by testing their intuitions against imaginary examples, could benefit from paying more attention to actual social science and real-world social problems. Ideally, these social metaphysicians should be engaged with philosophers of science in a joint effort to investigate whether a social account of scientific knowledge can explain something that an individualist account leaves out.

I argue against a priori objections to the view that causation may be reducible to some micro-structural process in principle discoverable by physics. I distinguish explanation from causation, and argue that the main objections to such a reduction stem from conflating these two notions. Explanation is the collection of pragmatically relevant, possibly counterfactual information about causation; and causation is to be identified in a necessary a posteriori way with whatever physical processes underwrite our explanatory claims.

Control theory is a popular theoretical framework for explaining cognitive domains such as motor control and “mindreading.” Such accounts frequently characterize their “internal models” as “simulating” things outside the brain. But in what sense are these “simulations”? Do they involve the kind of “replication” simulation found in the simulation theory of mindreading? I will argue that some but not all control -theoretic appeals to “simulation” involve R-simulation. To do so, I examine in detail a recent computational model of motor control (...) and action perception based in control theory. I argue that the architecture does not use R-simulation during motor control, but does during action perception. A novel result of this analysis is that the forward model—the control - theoretic mechanism most often described as performing simulation—is not well characterized in terms of R- simulation. I conclude with some lessons for research on the mechanisms of mindreading. (shrink)

The relationship between business and society changes over time, and periodically there is a ‘legitimization crisis’. The paper will briefly explore some important questions about company legitimacy: why is company legitimacy important; why do legitimacy crises occur; and finally, are we in a crisis at the moment, and if so how can it be solved? The legal institutionalization of business firms prescribes narrow accountabilities and limited responsibilities: the challenge for business in the new millennium is to open these up and (...) to broaden our understanding of the social significance of business activity without destroying its wealth creating processes. This will require a rethinking of the relationship to the shareholder and a new definition of the relationship with stakeholders. (shrink)

This study assessed several ethical issues and judgments facing graduate teaching assistants. Psychology GTAs judged the ethics of a number of teaching-related behaviors and rated how frequently they practiced those behaviors. Judgments of how ethical GTAs believed various behaviors to be, and the frequency with which they engaged in them, varied somewhat based on age, gender, training, and other factors. Moreover, several discrepancies were found between ethical judgments and practice. For example, most GTAs judged it unethical to teach without adequate (...) preparation and to ignore unethical behavior of faculty, but most reported practicing these behaviors at least on occasion. These data highlight the risk for unethical behavior among GTAs and the lack of preparation for dealing with that risk. (shrink)

A new method is presented for constructing models of set theory, using a technique of forming pseudo-ultrapowers. In the presence of the axiom of choice, the traditional ultrapower construction has proven to be extremely powerful in set theory and model theory; if the axiom of choice is not assumed, the fundamental theorem of ultrapowers may fail, causing the ultrapower to lose almost all of its utility. The pseudo-ultrapower is designed so that the fundamental theorem holds even if choice fails; this (...) is arranged by means of an application of the omitting types theorem. The general theory of pseudo-ultrapowers is developed. Following that, we study supercompactness in the absence of choice, and we analyze pseudo-ultrapowers of models of the axiom of determinateness and various infinite exponent partition relations. Relationships between pseudo-ultrapowers and forcing are also discussed. (shrink)
