Frege famously held that numbers play the role of objects in our language and thought, and that this role is on display when we use sentences like "The number of Jupiter's moons is four". I argue that this role is an example of a general pattern that also encompasses persons, times, locations, reasons, causes, and ways of appearing or acting. These things are 'objects' simply in the sense that they are answers to questions: they are the sort of thing we (...) search for and specify during investigation or inquiry. I support this epistemological conception of objects by studying specificational sentences, a class of sentences which includes Frege's original example. I defend an analysis of such sentences as question-answer pairs, and show how to formally represent this analysis using game-theoretical semantics. (shrink)

Conditional inferences can be phrased with unspecific terms (“If a person is on a diet, then the person loses weight. A person is on a diet. The person loses weight”) or specific terms (“If Anna is on a diet, then Anna loses weight. Anna is on a diet. Anna loses weight”). We investigate whether the specificity of terms affects people's acceptance of inferences. In Experiment 1, inferences with specific terms received higher acceptance ratings than inferences with unspecific terms. In (...) Experiments 2 and 3, we used the same problems as in Experiment 1 but also problems with unspecific terms in the conditional and specific terms in the categorical and vice versa. When the conditional and the categorical had the same specificity, results were as in Experiment 1. When the specificity of the conditional and the categorical mismatched, acceptance ratings were lower. Our results illustrate the importance of phrasing on reasoning. (shrink)

How is it possible that works of art exist? How do we become receptive aesthetic subjects? The Specificity of the Aesthetic extends these fundamental ontological and phenomenological questions around which Georg Lukács's theory of art was organised. This late work of aesthetics seeks to solve a puzzle that neither philosophy nor socialist politics was able to: the fundamental ethical question of what individuals and humanity as a whole ought to do. Art offers Lukács the already-existing means through which the (...) damaged edifice of Marxism might be reconstructed on a durable basis on which to rest the philosophy, politics, and ethics of a non-Soviet-style Marxism. Erik M. Bachman, Ph.D. (2011), University of California at Santa Cruz, is a Lecturer at that university. Author of Literary Obscenities: U.S. Case Law and Naturalism after Modernism (2018), he has also published numerous essays on modernism, film, and Lukács. Tyrus Miller, Ph.D. (1994), Stanford University, is the Dean of the School of Humanities at the University of California at Irvine. He has published and edited many notable monographs and essays on modernism, critical theory, and the avant-garde. (shrink)

The specification and implementation of computational artefacts occurs throughout the discipline of computer science. Consequently, unpacking its nature should constitute one of the core areas of the philosophy of computer science. This paper presents a conceptual analysis of the central role of specification in the discipline.

The city of Tirana during the period of socialism (1944–1990) has been through a relatively large change in the field of construction. The motto of the time was standardization and typification in order to build quick, and to meet the needs of the population, fulfilling the demands of the market for new constructions. The quality of the constructions was very poor in terms of building materials and surface area predicted per inhabitance. Meanwhile, the predicted static parameters of the buildings reveal (...) to be in good performance. The specific area taken into consideration located in the outskirts of the inner historical ring of Tirana is characterized by constructions realized during 1965–1980. The buildings are standing using retaining walls, according to the technical construction parameters of the time. The aim of the questionnaire implementation in the neighborhood is to have better insights into the social, economic and inhabitance behavior within the neighborhood. It is going to be analyzed their lifestyle, pollution in the area, their level of satisfaction, the actual conditions of the buildings, electricity consumption, water consumption, heating and cooling instruments, ventilation habits, etc. The results showed that the level of loyalty to the buildings is high, although the building physical conditions are very poor and their level of satisfaction living in the neighborhood is above average. Their level of satisfaction considers more the location of the neighborhood than the physical conditions of the buildings. The inhabitance agreed with a hypothetic thermal performance improvement of their buildings although sometimes the additional surface is required as the main priority and as a very important quality of life parameter.

At workplaces where nanomaterials are produced or used, risk assessment and risk management are extremely difficult tasks since there is still limited evidence about the risks of nanomaterials. Measurement methods for nanoparticles are contested and safety standards have not yet been developed properly. To support compliance with the legal obligation of the employer to care for safe workplaces a large number of ‘soft’ regulatory tools have been proposed (e.g. codes of conduct, benchmarks, standards). However, it is not clear whether and (...) under which conditions soft regulation is complied with. This article discusses the potential advantages and drawbacks of soft regulation. It explores compliance issues when exposure measurement devices and other technology-related factors are involved. The exploration of three examples of soft regulation on occupational health and safety (a ministerial recommendation on preliminary exposure benchmarks, a nano-specific guidance of a chemical company and a public–private OHS guideline) shows that the capacity of the regulated parties to comply depends on the availability of appropriate technological devices and methods, technical expertise and other resources. When technological prerequisites are met, compliance is likely to increase. (shrink)

The processes mediating dynamic and flexible responding to rapidly changing task-environments are not well understood. In the present research we employ a Stroop procedure to clarify the contribution of context-sensitive control processes to online performance. In prior work Stroop interference varied as a function of probe location context, with larger Stroop interference occurring for contexts associated with a high proportion of congruent items [Crump, M. J., Gong, Z., & Milliken, B. . The context-specific proportion congruent stroop effect: location as a (...) contextual cue. Psychonomic Bulletin & Review, 13, 316–321.] Here, we demonstrate that this effect does not depend on awareness of the context manipulation, but that it can depend on attention to the predictive context dimension, and on the relative salience of the target and predictive context dimensions. We discuss the implications of our results for current theories of cognitive control. (shrink)

Binding specificity is a centrally important concept in molecular biology, yet it has received little philosophical attention. Here I aim to remedy this by analyzing binding specificity as a causal property. I focus on the concept’s role in drug design, where it is highly prized and hence directly studied. From a causal perspective, understanding why binding specificity is a valuable property of drugs contributes to an understanding of causal selection—of how and why scientists distinguish between causes, not (...) just causes from noncauses. In particular, the specificity of drugs is precisely what underwrites their value as experimental interventions on biological processes. (shrink)

본 논문은 여성주의적 실천의 한 방식으로서 장소 특정적 예술이 가질 수 있는 가능성을 미학적 관점에서 탐구하는 것을 목표로 한다. 현대예술의 일반적인 형식중의 하나로서 자리잡은 장소특정적 예술은, 장소라는 요소가 비판적 예술 실천(수행)에서 어떻게 문제적이 되는지 장소적 실천 일반에 대해서 시사하는 바가 크다. 그 중에서도 본 논문은 장소와 여성주의적 실천의 관계를 다루며, 이를 위해, 2000년대 이후 한국 여성예술가의 네 개의 장소특정적 예술들 - 예술가의 서사와 담론이 중심이 되어 장소화나 특정 장소 선정이 이루어지는 두 가지 경우, 특정 지역 관련 기획전시의 경우, 특정 지역연구 (...) 프로젝트의 경우-을 대표 사례로 고려하였다.BR 모더니즘 예술의 매체 특정성과 대조적으로, 장소 특정성은 예술이 놓여있는 사회제도적 장소에 대한 의식과 질문이 주요동기가 되기 때문에, 비판적 문화실천으로서 여성주의적 실천의 가능성이 탐색될 수 있다. 예술에서의 장소특정성이 여성주의적 실천으로 기능하기 위해서 우선적으로 선행되어야 할 것은 장소 혹은 장소정체성이라는 개념에 대한 재해석이다. 장소란 특정 지리적 입지에 교차하는 다양한 사회적 관계라는 비판지리학자 매시Massey의 주장에 따른다면, 장소를 재구성하고 재해석하는 행위는 모두 정치적 행위이며, 예술에서 지역적 정체성이라는 요소의 활용 역시 젠더나 인종, 지역 문제에 대한 진보적 실천의 방식이 될 수 있다. 여성주의적으로 의미있는 장소적 예술실천에서 중요한 것은 이처럼, 우선적으로는 관계적 장소개념에 의해 기존의 지역정체성이 역사적으로 어떻게 구성되었는지의 해체와 재해석, 즉 특정 장소 정체성에 대한 여성주의적 관점에서의 적극적 재해석이다. 또한 장소특정적 예술의 많은 형태가 특정 장소나 지역 연구프로젝트라는 특수한 예술 형식과 관련된다. 이같은 지역연구 프로젝트는 여성예술가(집단)가 그 지역 정체성을 재해석하는 것 뿐 아니라, 그 지역에 살고 있는 여성 공동체의 삶에 개입하게 된다. 따라서 장소특정적 실천이 여성주의적으로서 유의미하게 위해 중요한 두 번째 요소는, 타자로서의 예술가가 지역 공동체와 관계함에 있어 어떤 위치를 취하고 어떤 방식을 택할 것인가에 대한 미학적, 윤리학적 성찰이라고 할 수 있다.

In this target article we question the assumption that perception is divided into separate domains of vision, hearing, touch, taste, and smell. We review implications of this assumption for theories of perception and for our understanding of ambient energy arrays (e.g., the optic and acoustic arrays) that are available to perceptual systems. We analyze three hypotheses about relations between ambient arrays and physical reality: (1) that there is an ambiguous relation between ambient energy arrays and physical reality, (2) that there (...) is a unique relation between individual energy arrays and physical reality, and (3) that there is a redundant but unambiguous relation, within or across arrays, between energy arrays and physical reality. This is followed by a review of the physics of motion, focusing on the existence and status of referents for physical motion. Our review indicates that it is not possible, in principle, for there to be a unique relation between physical motion and the structure of individual energy arrays. We argue that physical motion relative to different referents is specified only in the global array, which consists of higher-order relations across different forms of energy. The existence of specificity in the global array is consistent with the idea of direct perception, and so poses a challenge to traditional, inference-based theories of perception and cognition. However, it also presents a challenge to much of the ecological approach to perception and action, which has accepted the assumption of separate senses. (shrink)

In light of the phenomenon of multiple realizability, many philosophers wanted to preserve the mind-brain identity theory by resorting to a “narrow reductive strategy” whereby one (a) finds mental properties which are (b) sufficiently narrow to avoid the phenomenon of multiple realization, while being (c) explanatorily adequate to the demands of psychological theorizing. That is, one replaces the conception of a mental property as more general feature of cognitive systems with many less general properties, for example, replacing the conception of (...) pain as a general property across different species with a number of species-specific kinds of pain. Many critics focused on (c), arguing that species-specific properties are not explanatorily adequate because they do not capture what is common in pain across species. In this paper I focused on (b). I argued that if one carries the narrow reductive strategy out in such a way to avoid all multiple realizability that occurs within a species, for example, accommodating individual differences by postulating a more narrow pain-relative-to-an-individual-at-a-time, then the result is for all intents and purposes a claim about tokens and not types or properties at all (the position is now about individuals having properties at times, a structured token event). I also added an important point about explanation, viz., that properties-relative-to-individuals-at-times would not serve the explanatory goals of science by failing to generalize to other individuals.

No one denies that people adapt what they say and how they interpret what is said to them, depending on their interactive partners. What is controversial is when and how they do so. Several psycholinguistics research programs have found what appear to be failures to adapt to partners in the early moments of processing and have used this evidence to argue for modularity in the language processing architecture, claiming that the system cannot take into account a partner’s distinct needs or (...) knowledge early in processing. We review the evidence for both early and delayed partner‐specific adaptations, and we identify some challenges and difficulties with interpreting this evidence. We then discuss new analyses from a previously published referential communication experiment (Metzing & Brennan, 2003) demonstrating that partner‐specific effects need not occur late in processing. In contrast to Pickering and Garrod (2004) and Keysar, Barr, and Horton (1998b), we conclude that there is no good evidence that early processing has to be be “egocentric,”“dumb,” or encapsulated from social knowledge or common ground, but that under some circumstances, such as when one partner has made an attribution about another’s knowledge or needs, processing can be nimble enough to adapt quite early to a perspective different from one’s own.

The article is a reappraisal of the requirement of maximal specificity (RMS) proposed by the author as a means of avoiding "ambiguity" in probabilistic explanation. The author argues that RMS is not, as he had held in one earlier publication, a rough substitute for the requirement of total evidence, but is independent of it and has quite a different rationale. A group of recent objections to RMS is answered by stressing that the statistical generalizations invoked in probabilistic explanations must (...) be lawlike, and by arguing that predicates fit for occurrence in lawlike statistical probability statements must meet two conditions, at least one of which is violated in each of the counterexamples adduced in the objections. These considerations suggest the conception that probabilistic-statistical laws concern the long-run frequency of some characteristic within a reference class as characterized by some particular "description" or predicate expression, and that replacement of such a description by a coextensive one may turn a statement that is lawlike into another that is not. Finally, to repair a defect noted by Grandy, the author's earlier formulation of RMS is replaced by a modified version. (shrink)

The presented paper addresses the concept of technoscience and its possible implications for technology assessment. Drawing on the discourse about converging technologies, it formulates the assumption that a general shift within science from epistemic cultures to techno-epistemic cultures lies at the heart of the propagated convergence between nano-, bio-, info- and cogno-sciences and technologies. This shift is adequately captured—so the main thesis—by the technoscience label. The paper elaborates on the shared characteristics of the new technosciences, especially their hybrid character and (...) their non-linear integration of basic research, object construction and technological innovation. Recent calls for new modes of technology governance (e.g. for upstream technology assessment and public participation) are discussed against the background of these technoscience characteristics. It is concluded that an adequate model of emerging technosciences and a detailed understanding of their characteristics is of paramount importance for current practices of technology assessment.

I use some recent formal work on measuring causation to explore a suggestion by James Woodward: that the notion of causal specificity can clarify the distinction in biology between permissive and instructive causes. This distinction arises when a complex developmental process, such as the formation of an entire body part, can be triggered by a simple switch, such as the presence of particular protein. In such cases, the protein is said to merely induce or "permit" the developmental process, whilst (...) the causal "instructions" for guiding that process are already prefigured within the cells. I construct a novel model that expresses in a simple and tractable way the relevant causal structure of biological development and then use a measure of causal specificity to analyse the model. I show that the permissive-instructive distinction cannot be captured by simply contrasting the specificity of two causes as Woodward proposes, and instead introduce an alternative, hierarchical approach to analysing the interaction between two causes. The resulting analysis highlights the importance of focusing on gene regulation, rather than just the coding regions, when analysing the distinctive causal power of genes. (shrink)

This study explores the effect of individuation training on the acquisition of race-specific expertise. First, we investigated whether practice individuating other-race faces yields improvement in perceptual discrimination for novel faces of that race. Second, we asked whether there was similar improvement for novel faces of a different race for which participants received equal practice, but in an orthogonal task that did not require individuation. Caucasian participants were trained to individuate faces of one race (African American or Hispanic) and to make (...) difficult eye-luminance judgments on faces of the other race. By equating these tasks we are able to rule out raw experience, visual attention, or performance/success-induced positivity as the critical factors that produce race-specific improvements. These results indicate that individuation practice is one mechanism through which cognitive, perceptual, and/or social processes promote growth of the own-race face recognition advantage. (shrink)

Multi-stakeholder initiatives are increasingly used as a default mechanism to address human rights challenges in a variety of industries. MSI is a designation that covers a broad range of initiatives from best-practice sharing learning platforms to certification bodies and those targeted at addressing governance gaps. Critics contest the legitimacy of the private governance model offered by MSIs. The objective of this paper is to theoretically develop a typology of MSIs, and to empirically analyze the legitimacy of one specific type of (...) MSI, namely industry-specific MSIs. We argue that industry-specific MSIs that set out to govern corporate behavior have great potential to develop legitimacy. We analyze two industry-specific MSIs—the Fair Labor Association and the Global Network Initiative—to get a better understanding of how these MSIs formed, how they define and enforce standards, and how they seek to ensure accountability. Based on these empirical illustrations, we discuss the value of this specific MSI model and draw implications for the democratic legitimacy of private governance mechanisms. (shrink)

What counts as human rationality: reasoning processes that embody content-independent formal theories, such as propositional logic, or reasoning processes that are well designed for solving important adaptive problems? Most theories of human reasoning have been based on content-independent formal rationality, whereas adaptive reasoning, ecological or evolutionary, has been little explored. We elaborate and test an evolutionary approach, Cosmides' social contract theory, using the Wason selection task. In the first part, we disentangle the theoretical concept of a “social contract” from that (...) of a “cheater-detection algorithm”. We demonstrate that the fact that a rule is perceived as a social contract — or a conditional permission or obligation, as Cheng and Holyoak proposed — is not sufficient to elicit Cosmides' striking results, which we replicated. The crucial issue is not semantic, but pragmatic: whether a person is cued into the perspective of a party who can be cheated. In the second part, we distinguish between social contracts with bilateral and unilateral cheating options. Perspective change in contracts with bilateral cheating options turns P & not-Q responses into not-P & Q responses. The results strongly support social contract theory, contradict availability theory, and cannot be accounted for by pragmatic reasoning schema theory, which lacks the pragmatic concepts of perspectives and cheating detection.

The recognition memory for inverted faces is especially difficult when compared with that for non-face stimuli. This face inversion effect has often been used as a marker of face-specific holistic processing. However, whether face processing without awareness is still specific remains unknown. The present study addressed this issue by examining the face inversion effect with the technique of binocular rivalry. Results showed that invisible upright faces could break suppression faster than invisible inverted faces. Nevertheless, no difference was found for invisible (...) upright houses and invisible inverted houses. This suggested that face processing without awareness is still specific. Some face-specific information can be processed by high-level brain areas even when that information is invisible. (shrink)

In “Why the generality problem is everybody’s problem,” Michael Bishop argues that every theory of justification needs a solution to the generality problem. He contends that a solution is needed in order for any theory to be used in giving an acceptable account of the justificatory status of beliefs in certain examples. In response, first I will describe the generality problem that is specific to process reliabilism and two other sorts of problems that are essentially the same. Then I will (...) argue that the examples that Bishop presents pose no such problem for some theories. I will illustrate the exempt theories by describing how an evidentialist view can account for the justification in the examples without having any similar problem. It will be clear that other views about justification are likewise unaffected by anything like the generality problem. (shrink)

According to Vallicella's 'Relations, Monism, and the Vindication of Bradley's Regress' (2002), if relations are to relate their relata, some special operator must do the relating. No other options will do. In this paper we reject Vallicella's conclusion by considering an important option that becomes visible only if we hold onto a precise distinction between the following three feature-pairs of relations: internality/externality, universality/particularity, relata-specificity/relata-unspecificity. The conclusion we reach is that if external relations are to relate their relata, they must (...) be relata-specific (and no special operator is needed). As it eschews unmereological complexes, this outcome is of relevance to defenders of the extensionality of composition. (shrink)

The paper aims to weaken a widespread argument against indexical contextualism regarding matters of personal taste. According to indexical contextualism, an utterance of “T is tasty” (where T is an object of taste) expresses the proposition that T is tasty for J (where J is a judge). This argument suggests that indexical contextualism cannot do justice to our disagreement intuitions regarding typical disputes about personal taste because it has to treat conversations in which one speaker utters “T is tasty” and (...) another responds with “T is not tasty” (referred to as ‘judge-non-specific conversations’ in this paper) as being on a par with conversations in which one speaker utters “T is tasty to me” and another responds with “T is not tasty to me” (referred to as ‘judge-specific conversations’). The argument has it that judge-specific conversations, unlike judge-non-specific conversations, do not contain disagreement between speakers. To defend indexical contextualism, some philosophers have proposed accounts (here referred to as ‘dual-proposition theories’) according to which utterances of “T is tasty” are used to communicate both the above kinds of semantically expressed proposition and some other kinds of proposition (like superiority propositions or metalinguistic propositions) that could be used to explain disagreements about taste. The paper defends two claims: First, it is argued that judge-specific conversations, or at least some of them, do contain disagreement between speakers, contrary to what the anti-indexical-contextualist argument supposes. Second, it is argued that dual-proposition indexical-contextualist theories fail to explain judge-specific conversations that are intuitively interpreted as containing disagreement. (shrink)

The epidemiologist Bradford Hill famously argued that in epidemiology, specificity of association (roughly, the fact that an environmental or behavioral risk factor is associated with just one or at most a few medical outcomes) is strong evidence of causation. Prominent epidemiologists have dismissed Hill’s claim on the ground that it relies on a dubious `one-cause one effect’ model of disease causation. The paper examines this methodological controversy, and argues that specificity considerations do have a useful role to play (...) in causal inference in epidemiology. More precisely, I argue that specificity considerations help solve a pervasive inferential problem in contemporary epidemiology: the problem of determining whether an exposure-outcome correlation might be due to confounding by a social factor. This examination of specificity has interesting consequences for our understanding of the methodology of epidemiology. It highlights how the methodology of epidemiology relies on local tools designed to address specific inference problems peculiar to the discipline, and shows that observational causal inference in epidemiology can proceed with little prior knowledge of the causal structure of the phenomenon investigated. I also argue that specificity of association cannot (despite claims to the contrary) be entirely explained in terms of Woodward’s well-known concept of “one-to-one” causal specificity. This is because specificity as understood by epidemiologists depends on whether an exposure (or outcome) is associated with a `heterogeneous’ set of variables. This dimension of heterogeneity is not captured in Woodward’s notion, but is crucial for understanding the evidential import of specificity of association. (shrink)

A cause may influence its effect via multiple paths. Paradigmatically (Hesslow [1974]), taking birth control pills both decreases one’s risk of thrombosis by preventing pregnancy and increases it by producing a blood chemical. Building on Pearl ([2001]), I explicate the notion of a path-specific effect. Roughly, a path-specific effect of C on E via path P is the degree to which a change in C would change E were they to be transmitted only via P. Facts about such effects may (...) be gleaned from the structural equations commonly used to represent the causal relationships among variables. I contrast my analysis of the Hesslow case with those given by theorists of probabilistic causality, who mistakenly link it to issues of causal heterogeneity, token-causation and indeterminism. The reason probabilistic theories misdiagnose this case is that they pay inadequate attention to the structural relationships among variables. (shrink)

The notion of specification plays a key role in the developing science of computing. It is typically considered to be the keystone in the software development process. However, there is no single, generally agreed meaning of specification that bears close scrutiny. Instead there is a variety of different, although partially interlocking and overlapping interpretations of the term.We catalogue this varietal profusion and attempt to lay bare both the sources and consequences of each major alternative. We attempt to present the full (...) range of possibilities, and the biases inherent in each style of interpretation. (shrink)

Recent research suggests that processing of irrelevant information can be modulated in a rapid online fashion by contextual information in the task environment depending on the usefulness of that information in different contexts. Congruency effects evoked by irrelevant stimulus attributes are smaller in contexts with high proportions of incongruent trials and larger in contexts with high proportions of congruent trials . The present study investigates these context-adaptation effects in a masked-priming paradigm. Context-specific adaptation effects transfer to stimulus identities that are (...) equiprobale in all contexts – an observation that renders explanations in terms of event-learning processes unlikely. Yet, context-specific effects vanished when the irrelevant information remained unconscious. The results suggest that context-specific adaptation of congruency effects reflect cognitive control operations that alter the processing of irrelevant information depending on the experienced utility of that information for action control.

Phenotypic divergence among animal species may be due in part to species‐specific (SS) regulation of gene expression by small, non‐coding regulatory RNAs termed “microRNAs”. This phenomenon can be modulated by several variables. First, microRNA genes vary by their level of conservation, many of them being SS, or unique to a particular evolutionary lineage. Second, microRNA expression levels vary spatially and temporally in different species. Lastly, while microRNAs bind the 3′UTR of target genes in order to silence their expression, the binding (...) sites themselves are often non‐conserved. The variability of the miRNA‐target paradigm between different species is thus multifactorial, and this paradigm has only just started to gain attention from researchers in various fields. Here we present and discuss recent findings regarding the characteristics and implications of SS microRNA regulation. (shrink)

Children tend to extend object names on the basis of sameness of shape, rather than size, color, or materialFa tendency that has been dubbed the ‘‘shape bias.’’ Is the shape bias the result of well-learned associations between words and objects? Or does it exist because of a general belief that shape is a good indicator of object category membership? The present three studies addressed this debate by exploring whether the shape bias is specific to naming. In Study 1, 3-year-olds showed (...) the shape bias both when asked to extend a novel name and when asked to select an object of the same kind as a target object. Study 2 found the same shape bias when children were asked to generalize properties relevant to category membership. Study 3 replicated the findings from Study 1 with 2-year-olds. These findings suggest that the shape bias derives from children’s beliefs about object kinds and is not the product of associative learning. (shrink)
