A fixed-parameter is an algorithm that provides an optimal solution to a combinatorial problem. This research-level text is an application-oriented introduction to the growing and highly topical area of the development and analysis of efficient fixed-parameter algorithms for hard problems. The book is divided into three parts: a broad introduction that provides the general philosophy and motivation; followed by coverage of algorithmic methods developed over the years in fixed-parameter algorithmics forming the core of the book; and a discussion of the (...) essential from parameterized hardness theory with a focus on W [1]-hardness, which parallels NP-hardness, then stating some relations to polynomial-time approximation algorithms, and finishing up with a list of selected case studies to show the wide range of applicability of the presented methodology. Aimed at graduate and research mathematicians, programmers, algorithm designers and computer scientists, the book introduces the basic techniques and results and provides a fresh view on this highly innovative field of algorithmic research.

A centerpiece of Juhani Yli-Vakkuri and John Hawthorne’s Narrow Content (OUP 2018) is the parameter proliferation argument. The authors consider a series of cleverly constructed cases of pairs of corresponding thoughts of qualitatively identical twins and argue that divergence in truth value for such thoughts forces the internalist to admit novel alethic parameters for semantic evaluation that are not independently motivated. I argue that the internalist will resist this argument by denying that such pairs of thoughts diverge in truth (...) value. I then argue that the construal of content presupposed by the argument should be rejected or amended by the internalist on independent grounds. I end in a more diagnostic vein by considering why parameter proliferation might have seemed pressing for internalism to begin with. (shrink)

The Iowa Gambling Task (IGT) and the Soochow Gambling Task (SGT) are two experience-based risky decision-making tasks for examining decision-making deficits in clinical populations. Several cognitive models, including the expectancy-valence learning model (EVL) and the prospect valence learning model (PVL), have been developed to disentangle the motivational, cognitive, and response processes underlying the explicit choices in these tasks. The purpose of the current study was to develop an improved model that can fit empirical data better than the EVL and (...) PVL models and, in addition, produce more consistent parameter estimates across the IGT and SGT. Twenty-six opiate users (mean age 34.23; SD 8.79) and 27 control participants (mean age 35; SD 10.44) completed both tasks. Eighteen cognitive models varying in evaluation, updating, and choice rules were fit to individual data and their performances were compared to that of a statistical baseline model to find a best fitting model. The results showed that the model combining the prospect utility function treating gains and losses separately, the decay-reinforcement updating rule, and the trial-independent choice rule performed the best in both tasks. Furthermore, the winning model produced more consistent individual parameter estimates across the two tasks than any of the other models. (shrink)

Using the latest educational technologies and active methods of social activity development in future specialists in the educational space under today’s conditions is significantly complicated by existing levels of the object and subject studies of various patterns. The authors studied a wide range of foreign and domestic interdisciplinary works and models which describe the implementation of research methodology of the individual socialization process to study the development of specialists’ social activity. Also, the authors defined the relevant patterns of students’ involving (...) in socially significant activities due to the changes in value-motivational aspects at different stages of social activity development at the higher education institution. The structural and functional components are determined, and the research parameters specifying the changes of value-motivational factors of social activity development in future socionomy specialists are substantiated. The article provides empirical diagnostics of values among the students of socionomic professions within the sociological and pedagogical research of social activity with the participation of 610 students from four Ukrainian higher education institutions. The diagnostics was carried out by means of the shortened version of the “Portrait Questionnaire of Values - PVQ-Revised”. It has been found out that the development of social activity in future socionomy specialists is mainly related to changes in motivational aspects at different levels of generality and complexity; it includes such constructs as values, goals, behavior plans which require a qualitative analysis of social factors and identification of relevant patterns of students’ involvement in socially significant activities.

Moral internalism and moral externalism compete over the best explanation of the link between judgment and relevant motivation but, it is argued, they differ at best only verbally. The internalist rational-conceptual nature of the link’ as accounted by M. Smith in The Moral Problem is contrasted to the externalist, also rational, link that requires in addition support from the agent’s psychological-dispositional profile; the internalist link, however, is found to depend crucially on a, similarly to the externalist, psychologically ‘loaded’ profile. It (...) is also argued that the differentiation of the two competing explanations is insufficient partly because they both fail to consider crucial quantitative parameters of the judgment-motivation link. Such parameters become very important particularly in the light of Smith’s claim that this link is grounded on the observable “striking fact” where changes in the set of one’s moral beliefs systematically bring about changes in one’s moral behavior. Examples of algorithms measuring moral coherence and moral worth are provided to serve as evidence for what it comes down to, vis-à-vis the alleged fact, only a verbal dispute between the two camps. Finally, the ‘misfiring’ of these explanations is understood in connection to the irreducibility of concepts such as ‘moral worth’, and/or, ‘moral sensitivity’. (shrink)

ObjectiveThis study aims to evaluate the effectiveness of the MotivAir program—a phone-based intervention based on Motivational Interviewing principles and techniques—in enhancing adherence to Continuous Positive Airway Pressure therapy among patients with Obstructive Sleep Apnea Syndrome.MethodsA multicenter randomized controlled trial design with random allocation at the level of the individual will be conducted to compare the impact of the experimental program with a control group receiving usual care only in improving selected clinical and psychological parameters in the patients. A (...) minimum sample of 80 participants will be recruited in each center according to the inclusion criteria. After the initial screening, participants will be randomly assigned to either the experimental group or the control condition. The program will last 180 days and will be delivered by a trained nurse. The impact of the MotivAir program on selected primary and secondary outcomes will be measured at baseline, and after 1-, 3-, and 6-month from CPAP initiation.DiscussionParticipants are expected to show an increased level of adherence to CPAP and to acquire the skills and self-confidence necessary to deal with the psychological consequences of their chronic condition.

The proponents of strong lexicalism hold the view that “words” are formed in the lexicon and are opaque for the syntax ((Dowty 1979), (DiSciullo and Williams 1987), (Jackendoff 1990) and many others). Modular morphology, on the other hand, offers the possibility that at least some words are partially formed in the syntax ((Baker 1988), (Borer 1988), (Hale and Keyser 1994), (Chomsky 1995) and many others). In (Stechow 1995) and (Stechow 1996) it has been argued that facts observed with German wieder (...) “again” cannot be accounted for within the framework of strong lexicalism and therefore favour the second position. The authors of this paper want to check these claims by investigating the behaviour of the German adverb fast “ almost”, the other classical adverb to which the method of decomposition has been applied in the linguistic literature (cf. (McCawley 1971)). Most adverbs cannot look into lexical decomposition structures, but some can. In order to have a suitable name, let us call these D-adverbs. Again and almost are the prototypical representatives of this class. The method adopted is to investigate whether fast has access to different aspects of verbal meaning depending on its position. Following (Dowty 1979), resultative verbs and prepositions are decomposed into BECOME + XP, where XP is the result state. Agentive verbs contain an additional AGENT part. Other thematic relations connecting the subject and the event are HOLDER and cause. If the syntax tells us that an adverb like wieder or fast must have wide scope with respect to BECOME, then we expect other readings than in a configuration where fast can have narrow scope with respect to BECOME. In other words, the motivation for decomposition is syntactic and semantic. The idea is that certain function projections in the classical VP have a meaning and hence scopally interact with adverbs.

The susceptibility of Habermas' socio-political theory to the charge of motivational impotence can be traced to a problem in the way in which he conceives of discursive practical reason.

Within the framework of cognitive linguistics and construction grammar, it is claimed in this paper that the semantics of psuche is motivated by cognitive, cultural, and constructional parameters of meaning. More specifically, it is argued that psyche, as the immaterial nature of a human being, and the seat of emotions and feelings in particular, is understood in terms of image-based metaphors, a cultural model of the self, and a cultural narrative of existence. It is also argued that the frequent (...) occurrence of psyche in a number of collocations and idioms motivates and constrains constructional meaning. At the same time, constructions motivate extended senses of this word, thereby contributing to its polysemy and ultimately to semantic change. The evidence presented within this framework argues against a fixed borderline between lexical and constructional meaning. This view, long and tacitly adopted in lexicographic practice by necessity, is gaining further support within current research in the framework of lexicography, corpus linguistics, lexical semantics, language change, and construction grammar.

The aim of Pyrrhonism is deceptively simple: to achieve a state of ataraxia, of tranquility and relief from perturbation. But what is the extent of the ataraxia envisioned? Must the Skeptic admit a hard distinction between disturbances apparently related to belief and there­fore subject to suspension of judgement, and extra-doxastic disturbanc­es that are beyond the scope of the Skeptical method? In this paper I examine passages from Sextus’s Outlines of Pyrrhonism that indicate that such a distinction may not stand up (...) to Skeptical scrutiny and that the Skepti­cal method does not only apply to “philosophical” speculative dogma or to “intellectual” perturbation, contra Barnes’s claim that the person who perceives the fewest anomalies may make “the perfect Pyrrhonist”. But I also, following Massie’s critique of unwarranted causal inferences regarding the relation between equipollence and ataraxia, distinguish cases where tarache presents itself as anomalous and thus lends itself to inquiry from cases where it presents itself with an appar­ent cause and does not provoke inquiry. Thus, though an apparently extra-doxastic disturbance may actually be rooted in unconsciously-held dogma, the Skeptic cannot demarcate a special class of potentially doxastic disturbances without employing a dogmatic psychology of her own. She must instead suspend judgment regarding the entire scope of her method, entertaining the possibility that any disturbance could be relieved through the Skeptical method. In the process, ataraxia is divested of definite parameters and the Skeptical method becomes effectively endless. (shrink)

Michelle Madden Dempsey’s compelling book sets out a normative feminist argument as to why and when prosecutors should continue to pursue prosecutions in domestic violence cases where the victim refuses to participate in or has withdrawn their support for the prosecution. This paper will explore two of the key aspects of her argument—the centrality and definition of the concept of patriarchy, and the definition of domestic violence—before concluding with some final thoughts as to the appropriate parameters of feminist prosecutorial (...) decision-making. The paper argues that Madden Dempsey could offer a more detailed and nuanced argument about the role that patriarchy plays, particularly its relevance in marking out appropriate cases for pursuit; and that her thesis requires a more convincing exposition of the precise reasons for offering such a narrow account of domestic violence.

A recent surge of research has begun to examine music participation and well-being; however, a particular challenge with this work concerns theorizing around the associated well-being benefits of musical participation. Thus, the current research used Self-Determination Theory to consider the potential associations between basic psychological needs (competence, relatedness, and autonomy), self-determined autonomous motivation, and the perceived benefits to well-being controlling for demographic variables and the musical activity parameters. A sample of 192 Australian residents (17-85, Mage = 36.95), who were (...) currently participating in a musical activity at the time, completed an online questionnaire. Results indicated that females were more likely to perceive benefits to their well-being; and that how important an individual considers music in their life was positively related to perceived well-being. Importantly, the analyses also revealed that the basic needs of competency and relatedness were related to overall perceived well-being as well as specifically social, cognitive, and esteem dimensions of well-being. Autonomous motivation demonstrated significant associations with both an overall well-being score as well as four of five specific well-being subscales measured. Collectively, the findings indicate that Self-Determination Theory offers a useful theoretical framework to understanding the relationship between musical participation and well-being. Further, the pattern of findings reiterates the positive associations between musical participation and one’s psychosocial well-being, with broad implications for people involved in the facilitation of musical activity.

What motivates grandparents to their altruism? We review answers from evolutionary theory, sociology, and economics. Sometimes in direct conflict with each other, these accounts of grandparental investment exist side-by-side, with little or no theoretical integration. They all account for some of the data, and none account for all of it. We call for a more comprehensive theoretical framework of grandparental investment that addresses its proximate and ultimate causes, and its variability due to lineage, values, norms, institutions (e.g., inheritance laws), and (...) social welfare regimes. This framework needs to take into account that the demographic shift to low fecundity and mortality in economically developed countries has profoundly altered basic parameters of grandparental investment. We then turn to the possible impact of grandparental acts of altruism, and examine whether benefits of grandparental care in industrialized societies may manifest in terms of less tangible dimensions, such as the grandchildren's cognitive and verbal ability, mental health, and well-being. Although grandparents in industrialized societies continue to invest substantial amounts of time and money in their grandchildren, we find a paucity of studies investigating the influence that this investment has on grandchildren in low-risk family contexts. Under circumstances of duress there is converging evidence that grandparents can provide support that helps to safeguard their children and grandchildren against adverse risks. We conclude by discussing the role that grandparents could play in what has been referred to as Europe's demographic suicide. (shrink)

The motivation for this paper is the following: In [4] I showed that it is inconsistent with ZFC that the Maximality Principle for directed closed forcings holds at unboundedly many regular cardinals κ (even only allowing κ itself as a parameter in the Maximality Principle for < κ -closed forcings each time). So the question is whether it is consistent to have this principle at unboundedly many regular cardinals or at every regular cardinal below some large cardinal κ (instead of (...) ∞), and if so. how strong it is. It turns out that it is consistent in many cases, but the consistency strength is quite high. (shrink)

By a theorem of R. Kaye, J. Paris and C. Dimitracopoulos, the class of the Πn+1-sentences true in the standard model is the only consistent Πn+1-theory which extends the scheme of induction for parameter free Πn+1-formulas. Motivated by this result, we present a systematic study of extensions of bounded quantifier complexity of fragments of first-order Peano Arithmetic. Here, we improve that result and show that this property describes a general phenomenon valid for parameter free schemes. As a consequence, we obtain (...) results on the quantifier complexity, finite axiomatizability and relative strength of schemes for Δn+1-formulas. (shrink)

The economic importance of optimizing the environmental situation from the perspective of an entrepreneur are assessed in the article. The classification of administrative decisions taken in the course of the business activities is proposed. The authors identified a group of solutions directly providing optimization of environment external to the enterprise, solutions that have an indirect positive impact on the environment and solutions that improve ecology of industrial premises. The nature of economic effect of resulting solutions of various types is taken (...) into account. Vectors of influence of working conditions on the economic results of business activities are described. The nature and strength of the impact of model management decisions results of business activities are defined. Key performance indicators of entrepreneurial activity are identified: employee productivity, the amount of revenue and profitability, solvency, staff stability, the competitiveness of enterprises. Grouping the costs of ecological parameters optimization of the production environment is proposed. Relationship between level of working conditions and socio-psychological climate in the collective enterprise is disclosed. The methods of motivation of entrepreneurs in solving of environmental, production problems are considered. The role of training entrepreneurs engaged of medium and small businesses are underlined especially. Thus, in the article the relationship between environmental and economic problems of entrepreneurial activity is investigated. Role and opportunities of entrepreneurs in solving these problems are defined and structured. (shrink)

What philosophical motivations lay behind the emergence of the genealogical method in Foucault’s thought? Pace traditional interpretations, I argue that genealogy is best construed as a supplementary addition to the archaeological mode of investigation. It addresses an issue that arose within the problematic to which the archaeological method responds, but which that method was not designed to solve: the problem of “transcendental genesis” as this issue was defined within the unique parameters set forth by the French phenomenological tradition.

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

This paper is motivated by the increasing popularity of efficient designs for stated choice experiments. The objective in efficient designs is to create a stated choice experiment that minimizes the standard errors of the estimated parameters. In order to do so, such designs require specifying prior values for the parameters to be estimated. While there is significant literature demonstrating the efficiency improvements of employing efficient designs, the bulk of the literature tests conditions where the priors used to generate (...) the efficient design are assumed to be accurate. However, there is substantially less literature that compares how different design types perform under varying degree of error of the prior. The literature that does exist assumes small fractions are used, which is in contrast to computer-aided surveys that readily allow for large fractions. Further, the results in the literature are abstract in that there is no reference point to provide clear insight on the magnitude of any issue. Our objective is to analyze the robustness of different designs within a typical stated choice experiment context of a trade-off between price and quality. We use as an example transportation mode choice, where the key parameter to estimate is the value of time. Within this context, we test many designs to examine how robust efficient designs are against a misspecification of the prior parameters. The simple mode choice setting allows for insightful visualizations of the designs themselves and also an interpretable reference point for the range in which each design is robust. Not surprisingly, the D-efficient design is most efficient in the region where the true population VOT is near the prior used to generate the design: the prior is $20/h and the efficient range is $10–$30/h. However, the D-efficient design quickly becomes the most inefficient outside of this range, and the estimation significantly degrades above $50/h. The orthogonal and random designs are robust for a much larger range of VOT. The robustness of Bayesian efficient designs varies depending on the variance that the prior assumes. Implementing two-stage designs that first use a small sample to estimate priors are also not robust relative to uninformative designs. Arguably, the random design performs as well as any design, and it will perform even better if data cleaning is done to remove choice tasks where one alternative dominates the other. (shrink)

In this article, we will revisit a motivation to consider the advantages of a theory about structured contents over a semantics of possible worlds. We will argue that a structure represents the strategic organization of the content of “p” under conditions in which asserting it does not imply contradictory consequences. These are the winning conditions for the assertion of ‘p’. When ‘p’ is modally sensitive – it can change its winning parameters – knowledge of the structure thus represents the (...) rational point for assertions (about non-actualized realities) that are organized to maximize what can be deduced from ‘p’. In these cases, the known relevant structure is intensional. We will argue that actualist Possible World Semantics, seeking the conversion of intensional knowledge into a de re representation of possible states, pays the price of being blind to structural divergences; it can only poorly explain these structural divergences between non-actual states of information and correlate it with divergence between winning strategies of assertion. Our argument will begin exposing Frege’s legacy; resort to Dummett’s concept of ingredient sense as an alternative to Kripke’s grade two knowledge; and briefly go through a semantic strategy of Stalnaker and Thomason to represent modal statements. In addition to these authors, we will explore the contribution of Russell, Kaplan and Ecthemendy to our argument. (shrink)

An effective mechanism of personnel production behavior management in the system of enterprise's management to ensure the high performance indexes and enterprise's goals achievement is developed.

The implemented classification of motivate factors and of the potential as well as developed model of staff's production behavior management allows to determine the dependents between those variables and to propose the practical managerial tools that ensures attainment of company's goals. Based on the proposed model within further research it is advisable to develop a mechanism that takes into account the specific quantitative parameters of the components of the production behavior and is built on using identified at this stage dependencies. The model can be used in the formation of an effective personnel policy that will ensure the achievement of social and economic goals of the company. Implementation of the developed model in practice highlights the social responsibility of the enterprise, shifts the emphasis from a purely economic governance towards better integration of existing needs of employees.

What if gravity satisfied the Klein-Gordon equation? Both particle physics from the 1920s-30s and the 1890s Neumann-Seeliger modification of Newtonian gravity with exponential decay suggest considering a "graviton mass term" for gravity, which is _algebraic_ in the potential. Unlike Nordström's "massless" theory, massive scalar gravity is strictly special relativistic in the sense of being invariant under the Poincaré group but not the 15-parameter Bateman-Cunningham conformal group. It therefore exhibits the whole of Minkowski space-time structure, albeit only indirectly concerning volumes. Massive (...) scalar gravity is plausible in terms of relativistic field theory, while violating most interesting versions of Einstein's principles of general covariance, general relativity, equivalence, and Mach. Geometry is a poor guide to understanding massive scalar gravity: matter sees a conformally flat metric due to universal coupling, but gravity also sees the rest of the flat metric in the mass term. What is the 'true' geometry, one might wonder, in line with Poincaré's modal conventionality argument? Infinitely many theories exhibit this bimetric 'geometry,' all with the total stress-energy's trace as source; thus geometry does not explain the field equations. The irrelevance of the Ehlers-Pirani-Schild construction to a critique of conventionalism becomes evident when multi-geometry theories are contemplated. Much as Seeliger envisaged, the smooth massless limit indicates underdetermination of theories by data between massless and massive scalar gravities---indeed an unconceived alternative. At least one version easily could have been developed before General Relativity; it then would have motivated thinking of Einstein's equations along the lines of Einstein's newly re-appreciated "physical strategy" and particle physics and would have suggested a rivalry from massive spin 2 variants of General Relativity. The Putnam-Grünbaum debate on conventionality is revisited with an emphasis on the broad modal scope of conventionalist views. Massive scalar gravity thus contributes to a historically plausible rational reconstruction of much of 20th-21st century space-time philosophy in the light of particle physics. An appendix reconsiders the Malament-Weatherall-Manchak conformal restriction of conventionality and constructs the 'universal force' influencing the causal structure. Subsequent works will discuss how massive gravity could have provided a template for a more Kant-friendly space-time theory that would have blocked Moritz Schlick's supposed refutation of synthetic _a priori_ knowledge, and how Einstein's false analogy between the Neumann-Seeliger-Einstein modification of Newtonian gravity and the cosmological constant \Lambda generated lasting confusion that obscured massive gravity as a conceptual possibility.

In this work, we question the ability of existing ranking-based semantics to capture persuasion settings, emphasising in particular the phenomena of procatalepsis and of fading. Some widely accepted principles of ranking-based semantics are incompatible with a faithful treatment of these phenomena, which means that no existing ranking-based semantics can capture these two principles together. This motivates us to introduce a new parametrized ranking-based semantics based on the notion of propagation which extends the existing propagation semantics 139–150) by adding an additional (...) parameter allowing us to gradually decrease the impact of arguments when the length of the path between two arguments increases. We show that this parameter gives the possibility of choosing if one wants to satisfy the property Void Precedence or not and to control the scope of the impact of the arguments. We also propose an experiment to show that the new semantics remains stable when this parameter varies and an axiomatic evaluation to compare it with existing ranking-based semantics in the literature.

Previous studies of auditory expectation have focused on the expectedness perceived by listeners retrospectively in response to events. In contrast, this research examines predictive uncertainty —a property of listeners' prospective state of expectation prior to the onset of an event. We examine the information-theoretic concept of Shannon entropy as a model of predictive uncertainty in music cognition. This is motivated by the Statistical Learning Hypothesis, which proposes that schematic expectations reflect probabilistic relationships between sensory events learned implicitly through exposure. Using (...) probability estimates from an unsupervised, variable-order Markov model, 12 melodic contexts high in entropy and 12 melodic contexts low in entropy were selected from two musical repertoires differing in structural complexity (simple and complex). Musicians and non-musicians listened to the stimuli and provided explicit judgments of perceived uncertainty (explicit uncertainty). We also examined an indirect measure of uncertainty computed as the entropy of expectedness distributions obtained using a classical probe-tone paradigm where listeners rated the perceived expectedness of the final note in a melodic sequence (inferred uncertainty). Finally, we simulate listeners' perception of expectedness and uncertainty using computational models of auditory expectation. A detailed model comparison indicates which model parameters maximize fit to the data and how they compare to existing models in the literature. The results show that listeners experience greater uncertainty in high-entropy musical contexts than low-entropy contexts. This effect is particularly apparent for inferred uncertainty and is stronger in musicians than non-musicians. Consistent with the Statistical Learning Hypothesis, the results suggest that increased domain-relevant training is associated with an increasingly accurate cognitive model of probabilistic structure in music.

Tournament-like promotion systems are the default in audit firms, which are generally internally owned professional partnerships. While awarding promotions in a contest-like fashion stimulates contestants’ motivation and productivity, it may also upset an organizations’ ethical climate and trigger ethically adverse behaviors. Since nearly all research on promotion tournaments in management has been conducted in public firms, little is known about how these incentive systems operate in professional partnerships. In this study, we analyze how the perception of the two controllable design (...) parameters of promotion tournaments—the relative pay spread between winners and losers and tournament breadth in terms of the number of contestants that compete for a prize—affects audit firm behavior. Survey results provide evidence that the tournament’s perceived breadth prompts adverse behavior, as it does in public firms. Contrary to conventional wisdom, however, the perceived pay spread has no significant effect on adverse behavior, but triggers desirable behaviors instead. Our study suggests that promotion tournaments indeed provide powerful incentives, but also that understanding the unintended consequences of these incentives on organizational ethical climates and behavior requires tournament theory to be contextualized when it is applied in new settings like internally owned professional partnerships.

Emotion influences parameters of goal-directed whole-body movements in several ways. For instance, previous research has shown that approaching (moving toward) pleasant stimuli is easier compared to approaching unpleasant stimuli. However, some studies found that when emotional pictures are viewed for a longer time, approaching unpleasant stimuli may in fact be facilitated. The effect of viewing duration may have modulated whole-body approach movement in previous research but this has not been investigated to date. In the current study, participants initiated a (...) step forward after viewing neutral, high-arousal pleasant and high-arousal unpleasant stimuli. The viewing duration of the stimuli was set to seven different durations, varying from 100 to 4000 ms. Valence and arousal scores were collected for all stimuli. The results indicate that both viewing duration and the arousal of the stimuli influence kinematic parameters in forward gait initiation. Specifically, longer viewing duration, compared to shorter viewing duration, (a) diminished the step length and peak velocity in both neutral and emotional stimuli, (b) increased reaction time in neutral stimuli and, (c) decreased reaction time in pleasant and unpleasant stimuli. Strikingly, no differences were found between high-arousal pleasant and high-arousal unpleasant stimuli. In other words, the valence of the stimuli did not influence kinematic parameters of forward step initiation. Instead the arousal level (neutral: low; pleasant and unpleasant: high) explained the variance found in the results. The kinematics of forward gait initiation seemed to be reflected in the subjective arousal scores, but not the valence scores. So it seems arousal affects forward gait initiation parameters more strongly than valence. In addition, longer viewing duration seemed to cause diminished alertness, affecting GI parameters. These results shed new light on the prevailing theoretical interpretations regarding approach motivation in the literature, which warrants further examination in future research. (shrink)

A central question in online human sentence comprehension is, “How are linguistic relations established between different parts of a sentence?” Previous work has shown that this dependency resolution process can be computationally expensive, but the underlying reasons for this are still unclear. This article argues that dependency resolution is mediated by cue‐based retrieval, constrained by independently motivated working memory principles defined in a cognitive architecture. To demonstrate this, this article investigates an unusual instance of dependency resolution, the processing of negative (...) and positive polarity items, and confirms a surprising prediction of the cue‐based retrieval model: Partial‐cue matches—which constitute a kind of similarity‐based interference—can give rise to the intrusion of ungrammatical retrieval candidates, leading to both processing slow‐downs and even errors of judgment that take the form of illusions of grammaticality in patently ungrammatical structures. A notable achievement is that good quantitative fits are achieved without adjusting the key model parameters. (shrink)

A large body of research in cognitive psychology and neuroscience draws on Bayesian statistics to model information processing within the brain. Many theorists have noted that this research seems to be in tension with a large body of experimental results purportedly documenting systematic deviations from Bayesian updating in human belief formation. In response, proponents of the Bayesian brain hypothesis contend that Bayesian models can accommodate such results by making suitable assumptions about model parameters. To make progress in this debate, (...) I argue that it is fruitful to focus not on specific experimental results but rather on what I call the ‘sources of epistemic irrationality’ in human cognition. I identify four such sources and I explore whether and, if so, how Bayesian models can be reconciled with them: processing costs, evolutionary suboptimality, motivated cognition, and error management. 1 Introduction 2 The Bayesian Brain 3 The Problem of Epistemic Irrationality 3.1 Bayesian inference and rationality 3.2 Intuitive Bayesian inference 4 Sources of Epistemic Irrationality 4.1 Processing costs 4.2 Evolutionary suboptimality 4.3 Motivational influences 4.4 Error management 5 Conclusion.

Cranial electrotherapy stimulation is a neuromodulation tool used for treating several clinical disorders, including insomnia, anxiety, and depression. More recently, a limited number of studies have examined CES for altering affect, physiology, and behavior in healthy, non-clinical samples. The physiological, neurochemical, and metabolic mechanisms underlying CES effects are currently unknown. Computational modeling suggests that electrical current administered with CES at the earlobes can reach cortical and subcortical regions at very low intensities associated with subthreshold neuromodulatory effects, and studies using electroencephalography (...) and functional magnetic resonance imaging show some effects on alpha band EEG activity, and modulation of the default mode network during CES administration. One theory suggests that CES modulates brain stem, limbic, and cortical regions and increases relative parasympathetic to sympathetic drive in the autonomic nervous system. There is no direct evidence supporting this theory, but one of its assumptions is that CES may induce its effects by stimulating afferent projections of the vagus nerve, which provides parasympathetic signals to the cardiorespiratory and digestive systems. In our critical review of studies using CES in clinical and non-clinical populations, we found severe methodological concerns, including potential conflicts of interest, risk of methodological and analytic biases, issues with sham credibility, lack of blinding, and a severe heterogeneity of CES parameters selected and employed across scientists, laboratories, institutions, and studies. These limitations make it difficult to derive consistent or compelling insights from the extant literature, tempering enthusiasm for CES and its potential to alter nervous system activity or behavior in meaningful or reliable ways. The lack of compelling evidence also motivates well-designed and relatively high-powered experiments to assess how CES might modulate the physiological, affective, and cognitive responses to stress. Establishing reliable empirical links between CES administration and human performance is critical for supporting its prospective use during occupational training, operations, or recovery, ensuring reliability and robustness of effects, characterizing if, when, and in whom such effects might arise, and ensuring that any benefits of CES outweigh the risks of adverse events.

Religions commonly are taken to provide general orientation in leading one's life. We develop here the idea that religions also may have a much more concrete guidance function in providing systematic decision biases in the face of cognitive-control dilemmas. In particular, we assume that the selective reward that religious belief systems provide for rule-conforming behavior induces systematic biases in cognitive-control parameters that are functional in producing the wanted behavior. These biases serve as default values under uncertainty and affect performance (...) in any task that shares cognitive-control operations with the religiously motivated rule-conforming behavior the biases were originally developed for. Such biases therefore can be unraveled and objectified by means of rather simple tasks that are relatively well understood with regard to the cognitive mechanisms they draw on. (shrink)

Two questions are raised for Grafen’s formal darwinism project of aligning evolutionary dynamics under natural selection with the optimization of phenotypes for individuals of a population. The first question concerns mean fitness maximization during frequency-dependent selection; in such selection regimes, not only is mean fitness typically not maximized but it is implausible that any parameter closely related to fitness is being maximized. The second question concerns whether natural selection on inclusive fitness differences can be regarded as individual selection or whether (...) it leads to a departure from the central motivation that led to the formal darwinism project, viz., to show that “Darwinian” evolution through individual selection leads to “good design” or phenotypic adaptation through trait optimization.

Davydov’s mathematics curriculum was designed according to the principles of the Cultural Historical Activity Theory. In this study, we analyzed some developmental effects of its realization in Grade 1, in relation to the children’s school readiness level, and their teacher’s experience. We assessed two groups of developmental effects: some general math abilities ; and some abilities, which are very specific to Davydov’s mathematics curriculum. At the beginning of the Grade 1, we divided all participants into three groups according to their (...) level of motivation, voluntary regulation, and logical preservation in terms of J. Piaget. After 1 year we measured general effects again and also measured specific effects. The results showed that all the children became significantly better in all general math abilities. It was also found that progress in math abilities does not depend on the initial level of school readiness of children. Children with different levels of voluntary regulation, motivational readiness, and the level of logical preservation show improvements in general math abilities. As for the mathematical skills specific to the Davydov’ program, the achieved level of their development is also not related to the initial parameters of readiness for school. Also, there were no differences in improvements in general effects and in specific effects between the classes with experienced and not-so-experienced teacher. So, there are some reasons to believe that the level of the child’s actual development does not play a fundamental role for education, which built in accordance with the principles of CHAT. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 34.3 (2001) 260-274 [Access article in PDF] Second Thoughts on the Critiques of Big Rhetoric Edward Schiappa This note is divided into three parts. First, I explore some answers to the question "How did Rhetoric get so Big?" Second, I review some of the more important criticisms of a "globalized" or "universalized" view of rhetorical studies. Finally, I contend that the critiques of Big Rhetoric do (...) not withstand scrutiny and ought to be dismissed for insufficient evidence. While there certainly are important issues for scholars of rhetorical studies to consider about how to enhance the quality and importance of our work, such issues should not include the concern that rhetoric has grown too "big."By "Big Rhetoric" I refer only to the theoretical position that everything, or virtually everything, can be described as "rhetorical." I refer to the growth of rhetorical scholarship in communication studies and other disciplines as the "popularization" of rhetorical studies. 1 Theories associated with Big Rhetoric are credited with popularizing or at least rationalizing what Herbert W. Simons (1990) calls the "rhetorical turn" in a variety of disciplines. Within the journals and conventions of members of the National Communication Association (NCA), popularization is often characterized by studies of the form "the rhetoric of X," where X could literally be anything. Outside of the NCA-defined parameters of communication studies, popularization is evidenced by the apparently ever-increasing ranks of scholars who use "rhetoric" as a relevant and important term of art within their scholarship. By either measure, it can be argued fairly convincingly that "rhetoric" has become a widely used construct in scholarship. What I wish to engage is the disputed desirability of broad definitions and the related popularization of rhetoric. [End Page 260] 1. Whence big rhetoric? There are a number of narratives on the rise of Big Rhetoric already in print in communication studies (Simons 1990; Gaonkar 1990), rhetoric and composition (Berlin 1987; Young and Goggin 1993), and interdisciplinary publications (Roberts and Good 1993; Mailloux 2000; Nelson, Megill, and McCloskey 1987). Many accounts identify the 1960s as a turning point. For better or for worse, there was a confluence of changing rhetorical practices, expanding rhetorical theories, and opportunities for rhetorical criticism. The cultural clashes of the 1960s were felt perhaps most acutely on college campuses. The sufficiency of deliberative argument and public address can be said to have been called into question, whether one was an antiwar activist who hated LBJ's war in Vietnam or a pro-establishment stalwart trying to make sense of the rhetoric of protest and demonstration. Years later, scholars would characterize war itself as rhetorical. What counted as rhetorical practice was up for grabs.At about the same time, our understanding of rhetorical theory was being expanded. Here we can identify two main strands of thought. For ease of reference I will call one the symbolic interactionist rationale and the other the epistemological rationale. The symbolic interactionist rationale can be boiled down to a syllogism: All persuasive actions are rhetorical. All symbol/language-use is persuasive. Therefore: All symbol/language-use is rhetorical. Perhaps the two most significant pronouncements of this approach--for my generation of rhetoric scholars, at any rate--are by Richard Weaver and Kenneth Burke. Weaver claims that "language is sermonic" in the sense that whenever we offer a description or label a phenomenon, we are "preaching" a particular way of making sense of it (1970, 201-25). Burke, of course, has two famous (or infamous) statements in Rhetoric of Motives: first, that rhetoric is "the use of language as a symbolic means of inducing cooperation in beings that by nature respond to symbols" (1950, 43); and second, that "something of the rhetorical motive comes to lurk in every 'meaning,' however purely 'scientific' its pretensions. Wherever there is persuasion, there is rhetoric. And wherever there is 'meaning,' there is 'persuasion'" (1950, 172). Obviously, such pronouncements serve as encouragement to [End Page 261] those who would define rhetoric broadly, and arguably fueled the popularization of rhetorical studies within the ranks of NCA.The epistemological rationale is fueled...

Inclusive fitness has been under intense scrutiny in recent years, with many critics claiming the framework leads to incorrect predictions. We consider one particularly influential heuristic for estimating inclusive fitness in the context of the very case that motivated reliance on it to begin with: the Sir Philip Sidney signalling game played with relatives. Using a neighbour-modulated fitness model, we show when and why this heuristic is problematic. We argue that reliance on the heuristic rests on a misunderstanding of what (...) it means for two organisms to be related and perpetuates a mischaracterization of the role of the ‘relatedness’ parameter in inclusive fitness. _1_ Introduction _2_ Heuristic Inclusive Fitness _3_ The Sir Philip Sidney Game _4_ Model _5_ Results _6_ Conclusion Appendix.

We consider several puzzles of bounded rationality. These include the Allais- and Ellsberg paradox, the disjunction effect, and related puzzles. We argue that the present account of quantum cognition—taking quantum probabilities rather than classical probabilities—can give a more systematic description of these puzzles than the alternate treatments in the traditional frameworks of bounded rationality. Unfortunately, the quantum probabilistic treatment does not always provide a deeper understanding and a true explanation of these puzzles. One reason is that quantum approaches introduce additional (...) parameters which possibly can be fitted to empirical data but which do not necessarily explain them. Hence, the phenomenological research has to be augmented by responding to deeper foundational issues. In this article, we make the general distinction between foundational and phenomenological research programs, explaining the foundational issue of quantum cognition from the perspective of operational realism. This framework is motivated by assuming partial Boolean algebras. They are combined into a uniform system via a mechanism preventing the simultaneous realization of perspectives. Gleason’s theorem then automatically leads to a distinction between probabilities that are defined by pure states and probabilities arising from the statistical mixture of pure states. This formal distinction relates to the conceptual distinction between risk and ignorance. Another outcome identifies quantum aspects in dynamic macro-systems using the framework of symbolic dynamics. Finally, we discuss several ideas that are useful for justifying complementarity in cognitive systems. (shrink)

The revised Common Rule includes a new option for the conduct of secondary research with identifiable data and biospecimens: regulatory broad consent. Motivated by concerns regarding autonomy and trust in the research enterprise, regulators had initially proposed broad consent in a manner that would have rendered it the exclusive approach to secondary research with all biospecimens, regardless of identifiability. Based on public comments from both researchers and patients concerned that this approach would hinder important medical advances, however, regulators decided to (...) largely preserve the status quo approach to secondary research with biospecimens and data. The Final Rule therefore allows such research to proceed without specific informed consent in a number of circumstances, but it also offers regulatory broad consent as a new, optional pathway for secondary research with identifiable data and biospecimens. In this article, we describe the parameters of regulatory broad consent under the new rule, explain why researchers and research institutions are unlikely to utilize it, outline recommendations for regulatory broad consent issued by the Secretary's Advisory Committee on Human Research Protections, and sketch an empirical research agenda for the sorts of questions about regulatory broad consent that remain to be answered as the research community embarks on Final Rule implementation.

We offer a general framework for theorizing about the structure of knowledge and belief in terms of the comparative normality of situations compatible with one’s evidence. The guiding idea is that, if a possibility is sufficiently less normal than one’s actual situation, then one can know that that possibility does not obtain. This explains how people can have inductive knowledge that goes beyond what is strictly entailed by their evidence. We motivate the framework by showing how it illuminates knowledge about (...) the future, knowledge of lawful regularities, knowledge about parameters measured using imperfect instruments, the connection between knowledge, belief, and probability, and the dynamics of knowledge and belief in response to new evidence.

In a recent paper, Pickel and Rabern (2016) argue that a dynamic Tarskian semantics resolves Fine’s antinomy of the variable without the radical consequences for semantics proposed by Fine (2003, 2007). While Pickel and Rabern’s basic insight—a parameter of discourse context that tracks occurrences of variable-binding expressions—is important, I will argue that their own Tarskian theory faces a destructive dilemma: either their theory does not resolve Fine’s antinomy as they propose, or their theory does not reflect the intuitive motivation for (...) what they call structured meanings. I suggest that in response to this dilemma we should reject one of the principles that generates Pickel and Rabern’s version of the antinomy. Here Pickel and Rabern’s insight has surprising, but salutary, foundational consequences for semantics. (shrink)

The paper investigates the effects of a humanoid robot’s online feedback during a tutoring situation in which a human demonstrates how to make a frog jump across a table. Motivated by micro-analytic studies of adult-child-interaction, we investigated whether tutors react to a robot’s gaze strategies while they are presenting an action. And if so, how they would adapt to them. Analysis reveals that tutors adjust typical “motionese” parameters. We argue that a robot – when using adequate online feedback strategies (...) – has at its disposal an important resource with which it could proactively shape the tutor’s presentation and help generate the input from which it would benefit most. These results advance our understanding of robotic “Social Learning” in that they suggest a paradigm shift towards considering human and robot as one interational learning system. Keywords: human-robot-interaction; feedback; adaptation; multimodality; gaze; conversation analysis; social learning; pro-active robot conduct. (shrink)

Continued concern for animal welfare may be alleviated when welfare would be monitored on farms. Monitoring can be characterized as an information system where various stakeholders periodically exchange relevant information. Stakeholders include producers, consumers, retailers, the government, scientists, and others. Valuating animal welfare in the animal-product market chain is regarded as a key challenge to further improve the welfare of farm animals and information on the welfare of animals must, therefore, be assessed objectively, for instance, through monitoring. Interviews with Dutch (...) stakeholder representatives were conducted to identify their perceptions about the monitoring of animal welfare. Stakeholder perceptions were characterized in relation to the specific perspectives of each stakeholder. While producers tend to perceive welfare from a production point of view, consumers will use visual images derived from traditional farming and from the animals’ natural environments. Scientists’ perceptions of animal welfare are affected by the need to measure welfare with quantifiable parameters. Retailers and governments (policy makers) have views of welfare that are derived from their relationships with producers, consumers, non-governmental organizations (NGOs), and scientists. All interviewed stakeholder representatives stated that animal welfare is important. They varied in the extent to which they weighted economic considerations relative to concern for the animals’ welfare. Many stakeholders emphasized the importance of communication in making a monitoring system work. Overall, the perspectives for the development of a sustainable monitoring system that substantially improves farm animal welfare were assessed as being poor in the short term. However, a reliable system could be initiated under certain conditions, such as integrated chains and with influential and motivated stakeholders. A scheme is described with attention points for the development of sustainable monitoring systems for farm animal welfare in the long term. (shrink)

The view that if-clauses function semantically as restrictors is widely regarded as the only candidate for a fully general account of conditionals. The standard implementation of this view assumes that, where no operator to be restricted is in sight, if-clauses restrict covert epistemic modals. Stipulating such modals, however, lacks independent motivation and leads to wrong empirical predictions. In this paper I provide a theory of conditionals on which if-clauses are uniformly interpreted as restrictors, but no covert modals are postulated. Epistemic (...) if-clauses, like those in bare conditionals, restrict an information state parameter which is used to interpret an expressive layer of the language. I show that this theory yields an attractive account of bare and overtly modalized conditionals and solves various empirical problems for the standard view, while dispensing with its less plausible assumption.

We show that previous results from epistemic network models showing the benefits of decreased connectivity in epistemic networks are not robust across changes in parameter values. Our findings motivate discussion about whether and how such models can inform real-world epistemic communities. As we argue, only robust results from epistemic network models should be used to generate advice for the real-world, and, in particular, decreasing connectivity is a robustly poor recommendation.

Taking regular walks when living with Parkinson’s disease has beneficial effects on movement and quality of life. Yet, patients usually show reduced physical activity compared to healthy older adults. Using auditory stimulation such as music can facilitate walking but patients vary significantly in their response. An individualized approach adapting musical tempo to patients’ gait cadence, and capitalizing on these individual differences, is likely to provide a rewarding experience, increasing motivation for walk-in PD. We aim to evaluate the observance, safety, tolerance, (...) usability, and enjoyment of a new smartphone application. It was coupled with wearable sensors and delivered individualized musical stimulation for gait auto-rehabilitation at home. Forty-five patients with PD underwent a 1-month, outdoor, uncontrolled gait rehabilitation program, using the BeatWalk application. The music tempo was being aligned in real-time to patients’ gait cadence in a way that could foster an increase up to +10% of their spontaneous cadence. Open-label evaluation was based on BeatWalk use measures, questionnaires, and a six-minute walk test. Patients used the application 78.8% of the prescribed duration and enjoyed it throughout the program. The application was considered “easy to use” by 75% of the patients. Pain, fatigue, and falls did not increase. Fear of falling decreased and quality of life improved. After the program, patients improved their gait parameters in the six-minute walk test without musical stimulation. BeatWalk is an easy to use, safe, and enjoyable musical application for individualized gait rehabilitation in PD. It increases “walk for exercise” duration thanks to high observance.Clinical Trial Registration: ClinicalTrials.gov Identifier: NCT02647242. (shrink)

Presence is a palpable sense of space, things and others that overlaps with matters of meaning, yet is not reducible to it: it is a dimension of things that hides in plain sight. This paper is motivated by observations that (1) presence is under-appreciated in questions of modern and nascent human-synthetic agent interaction, and (2) that presence matters because it affects and moves us. The paper’s goal is to articulate a multi-faceted understanding of presence, and why it matters, so the (...) importance of presence may be readily understood by those who regulate media, digital and artificial intelligence (AI) industries. Novel forms of presence raise all sorts of questions of what it means to live with new forms of presences. Some of these are highly positive and others are resistant to simplistic moral diagnosis, a point explored through extended consideration of ‘thanatechnology’ and ‘ghostbots’. To clarify and foreground presence, this paper draws on continental philosophy and technologist ideas about presence to understand the significance and parameters of presence. It then puts these to work by considering a range of existing and emerging human-synthetic agent interactions, arguing that that presence is an underappreciated yet crucial factor in human-synthetic interactions, particularly involving AI and ghostbots. The paper concludes with points of focus for organisations charged with media, data protection and AI governance regarding facets of presence-based characteristics for emergent human-synthetic interaction. Foremost is consideration of open standards for a presence-based afterlife and suggestion of a temporal firewall, or a break of time before resurrection, to prevent harm to those who have recently lost someone.

I suggest that the main aim Recanati proposes to achieve in Perspectival Though—that a moderate relativist should adopt a Kaplanian framework with three levels of content, rather than a Lewisian framework with only two— seems insufficiently motivated, and the arguments offered do not settle the issue. I suggest furthermore that the claim that subjects’ mental states and cognitive situations can determine parameters or indices in circumstances of evaluation is an original and very interesting contribution. It is also an important (...) one, since it sets further apart the radical from the moderate relativist, and it is relevant in the current relativism debate, where truth is deemed to be relative to parameters other than worlds, times, places and individuals. I also offer a few objections to some of the reasons Recanati puts forward in support of this latter claim; I object in particular to those that depend on some considerations about psychological modes.

Objects: To evaluate the feasibility and effectiveness of in-bed wearable elbow robot training for motor recovery in patients with early and late subacute stroke.Methods: Eleven in-patient stroke survivors received 15 sessions of training over about 4 weeks of hospital stay. During each hourly training, participants received passive stretching and active movement training with motivating games using a wearable elbow rehabilitation robot. Isometric maximum muscle strength of elbow flexors and extensors was evaluated using the robot at the beginning and end of (...) each training session. Clinical measures including Fugl-Meyer Assessment of upper extremity, Motricity Index for upper extremities, Modified Ashworth Scale were measured at baseline, after the 4-week training program, and at a 1-month follow-up. The muscle strength recovery curve over the training period was characterized as a logarithmic learning curve with three parameters.Results: At the baseline, participants had moderate to severe upper limb motor impairment {FMA-UE [median ]: 28 } and mild spasticity in elbow flexors {MAS [median ]: 0 }. After about 4 weeks of training, significant improvements were observed in FMA-UE and MI, and the improvements were sustained at the follow-up. The elbow flexors MVC significantly increased by 1.93 Nm and the elbow extensor MVC increased by 0.68 Nm. Muscle strength recovery curve showed that patients with severe upper limb motor impairment had a greater improvement rate in elbow flexor strength than those with moderate motor impairment.Conclusion: In-bed wearable elbow robotic rehabilitation is feasible and effective in improving biomechanical and clinical outcomes for early and late subacute stroke in-patients. Results from the pilot study suggested that patients with severe upper limb motor impairment may benefit more from the robot training compared to those with moderate impairment. (shrink)

Human-Computer Interaction (HCI) and games set a new domain in understanding people’s motivations in gaming, behavioral implications of game play, game adaptation to player preferences and needs for increased engaging experiences in the context of HCI serious games (HCI-SGs). When the latter relate with people’s health status, they can become a part of their daily life as assistive health status monitoring/enhancement systems. Co-designing HCI-SGs can be seen as a combination of art and science that involves a meticulous collaborative process. The (...) design elements in assistive HCI-SGs for Parkinson’s Disease (PD) patients, in particular, are explored in the present work. Within this context, the Game-Based Learning (GBL) design framework is adopted here and its main game-design parameters are explored for the Exergames, Dietarygames, Emotional games, Handwriting games, and Voice games design, drawn from the PD-related i-PROGNOSIS Personalized Game Suite (PGS) (www.i-prognosis.eu) holistic approach. Two main data sources were involved in the study. In particular, the first one includes qualitative data from semi-structured interviews, involving 10 PD patients and four clinicians in the co-creation process of the game design, whereas the second one relates with data from an online questionnaire addressed by 104 participants spanning the whole related spectrum, i.e., PD patients, physicians, software/game developers. Linear regression analysis was employed to identify an adapted GBL framework with the most significant game-design parameters, which efficiently predict the transferability of the PGS beneficial effect to real-life, addressing functional PD symptoms. The findings of this work can assist HCI-SG designers for designing PD-related HCI-SGs, as the most significant game-design factors were identified, in terms of adding value to the role of HCI-SGs in increasing PD patients’ quality of life, optimizing the interaction with personalized HCI-SGs and, hence, fostering a collaborative human-computer symbiosis.

In the recent literature on contextualism and relativism, one often finds disputes as to which kind of consideration would be relevant for positing a feature of a context as a parameter in the ‘‘circumstance of evaluation’: via the presence of an operator in the language which shifts that feature (Stanley) or by being a feature of a context with respect to which the truth of ‘‘propositions’’ expressed in the context is relative (McFarlane). This kind of dispute arises from two different (...) independent roles that elements in ‘‘circumstances of evaluation’’ are sometimes assumed to have. I distinguish indices from points of evaluation, and motivate its significance in the debate. (shrink)
