The notion of multiple location plays an important role in the characterization of endurantism. Several authors have recently offered cases intended to demonstrate the incoherence of multiple location. I argue that these cases do not succeed in making multiple location problematic. Along the way, several crucial issues about multiple location and its use by endurantists are clarified.

According to the broadly Aristotelian distinction between universals and particulars, all and only the former are capable of whole multiple location. The present essay defends this distinction against four putative counterexamples. The first two, extended simple material objects and enduring time-traveling self-meeters, putatively are wholly multiply locatable, but not universals. The second two, unique properties of point-sized entities and Platonic (i.e., not spatiotemporally located) universals, putatively are universals, but not wholly multiply locatable. The defensive strategy is to resist (...) certain presuppositions underlying the examples. (shrink)

This paper discusses how the possibility of multi-located entities can resolve problems both with the Trinity and with the existence of souls.

It is a common claim that one concept of time, tenseless theory, is in greater conflict with how the world seems to us than the competing theories of tense theory and presentism. This paper offers at least one counter-example to that claim. Here, it is argued that tenseless theory fares better than its competitors in capturing the phenomenology in particular cases of perception. These cases are where the visual phenomenology is of events occurring together which must be occurring at different (...) times. The commitments of matching such phenomenology in one’s ontology undermine tense theory and presentism and support tenseless theory. (shrink)

Is the fact that our universe contains fine-tuned life evidence that we live in a multiverse? Ian Hacking and Roger White influentially argue that it is not. We approach this question through a systematic framework for self-locating epistemology. As it turns out, leading approaches to self-locating evidence agree that the fact that our own universe contains fine-tuned life indeed confirms the existence of a multiverse. This convergence is no accident: we present two theorems showing that, in this setting, any updating (...) rule that satisfies a few reasonable conditions will have the same feature. The conclusion that fine-tuned life provides evidence for a multiverse is hard to escape. (shrink)

A longstanding issue in attempts to understand the Everett (Many-Worlds) approach to quantum mechanics is the origin of the Born rule: why is the probability given by the square of the amplitude? Following Vaidman, we note that observers are in a position of self-locating uncertainty during the period between the branches of the wave function splitting via decoherence and the observer registering the outcome of the measurement. In this period it is tempting to regard each branch as equiprobable, but we (...) argue that the temptation should be resisted. Applying lessons from this analysis, we demonstrate (using methods similar to those of Zurek's envariance-based derivation) that the Born rule is the uniquely rational way of apportioning credence in Everettian quantum mechanics. In doing so, we rely on a single key principle: changes purely to the environment do not affect the probabilities one ought to assign to measurement outcomes in a local subsystem. We arrive at a method for assigning probabilities in cases that involve both classical and quantum self-locating uncertainty. This method provides unique answers to quantum Sleeping Beauty problems, as well as a well-defined procedure for calculating probabilities in quantum cosmological multiverses with multiple similar observers.

The fact that physical laws often admit certain kinds of space-time symmetries is often thought to be problematic for substantivalism --- the view that space-time is as real as the objects it contains. The most prominent alternative, relationism, avoids these problems but at the cost of giving abstract objects (rather than space-time points) a pivotal role in the fundamental metaphysics. This incurs related problems concerning the relation of the physical to the mathematical. In this paper I will present a version (...) of substantivalism that respects Leibnizian theses about space-time symmetries, and argue that it is superior to both relationism and the more orthodox form of substantivalism.

This collection of writings by Jean-Luc Nancy, the renowned French critic and poet, delves into the history of philosophy to locate a fundamentally poetic modus operandi there. The book represents a daring mixture of Nancy’s philosophical essays, writings about artworks, and artwork of his own. With theoretical rigor, Nancy elaborates on the intrinsic multiplicity of art as a concept of “making,” and outlines the tensions inherent in the faire, the “making” that characterizes the very process of production and thereby the (...) structure of poetry in all its forms. Nancy shows that this multiplication that belongs to the notion of art makes every single work communicate with every other, all material in the artwork appeal to some other material, and art the singular plural of a praxis of the finite imparting of an infinity which is actually there in every utterance. In the collection, Nancy engages with the work of, among others, François Martin, Maurice Blanchot, and On Kawara. (shrink)

In the literature on multiple realizability and the identity theory, cases of neural plasticity have enjoyed a very limited role. The present article attempts to remedy this small influence by arguing that clinical and experimental evidence of quite extensive neural reorganization offers compelling support for the claim that psychological kinds are multiply realized in neurological kinds, thus undermining the identity theory. In particular, cases are presented where subjects with no measurable psychological deficits also have vast, though gradually received, neurological (...) damage. Common objections and concerns are also discussed and rejected. 1 Introduction2 The GRP, Serial Lesion Effect, and Multiple Realizability2.1 A case study of the serial lesion effect2.2 Evaluating the case study’s evidence for multiple realizability3 The GRP More Generally4 Objections to the GRP as Evidence for Multiple Realizability4.1 Small plastic effects and neurological taxonomies4.2 But do neural regions and locations even matter at all?4.3 But are there not other options besides location?5 Conclusion.

This paper explores concepts of multiple and nested identities and how these relate to citizenship and rights, and the implications of identities and rights for active citizenship education. Various theoretical conceptions of identity are analysed, and in particular ideas concerning multiple identities that are used contingently, and about identities that do not necessarily include feeling a strong affinity with others in the group. The argument then moves to the relationship between identity and citizenship, and particularly citizenship and rights. (...) Citizenship is treated non-legalistically, as one of the locations of belonging. The paper draws on three successive categorisations of citizenship rights: by T.H. Marshall in the 1950s, Karel Vasak in the late 1970s and John Urry in the 1990s, and is illustrated in part by the development of European citizenship in parallel to national identity. This is then linked to how contemporary citizenship education might use the exploration of contested rights as a way of developing practical enactive skills of citizenship. (shrink)

Mario Villalobos and Pablo Razeto-Barry argue that enactivists should understand living beings not as autopoietic systems, but as autopoietic bodies. In doing so, they surrender the principle of multiple realizability of the spatial location of living beings. By way of counterexample, I argue that more motivation is required before this principle is surrendered.

Many philosophers believe that there are both particulars and universals. Many of these philosophers, in turn, believe that universals are immanent. On this view, universals are wholly located where their instances are located. Both Douglas Ehring and E.J. Lowe have argued that immanent universals do not exist on the grounds that nothing can be wholly located in multiple places simultaneously without contradiction. In this paper, I focus on Lowe’s argument, which has received far less attention in the literature. Using (...) the theory of location found in Josh Parsons (2007), I show how Lowe’s argument against immanent universals can be resisted. (shrink)

The beginnings of epidemics are often told as if they are simple to locate in time. They take the form of a crisis, and as such, function as great synchronisers of different temporalities, bringing social temporalities “in line” with biological ones. In the case of the COVID-19 pandemic, for example, political processes that are usually slow were accelerated in order to “catch up with” the fast pace of the virus's reproduction, as policymakers saw a need to contain the virus. The (...) end of an epidemic, on the other hand, is more difficult to pinpoint. This can be attributed to the fact that the myriad actors involved in and affected by an epidemic operate on diverging time scales. Although seemingly synchronised from its outset, these lifetimes become un-synchronised as the epidemic unfolds. Some effects of an epidemic outbreak are easily observed, such as infection rates and the number of deceased. Others-psychological or medical after-effects, or the lasting memory in a population-may be harder to spot. Declaring that an epidemic has “ended” usually relies on the ceasing of the former, not the latter. However, as this article argues, the ending(s) of an epidemic should be regarded in the plural, each operating within its own rhythm and scale. This article explores the multiplicity of lifetimes involved in epidemics-human, microbial, institutional-and tries to give an explanation as to how epidemics end (or linger on) using an approach of multiple temporalities.

Even though the phenomenon of gentrification is ever-growing in contemporary urban contexts, especially in high income countries, it has been mostly overlooked by normative political theorists and philosophers. In this paper we examine the normative dimensions of gentrification through the lens of food. By drawing on Huber and Wolkenstein’s (Huber and Wolkenstein, Politics, Philosophy & Economics 17:378–397, 2018) work, we use food as an example to illustrate the multiple ways in which life plans can be located and to argue (...) that both existing residents and newcomers have an interest in occupancy rights. More specifically, while newcomers have an interest in moving freely to new neighbourhoods in order to purse their preferred life plans, they also have an interest in being able to continue to pursue those life plans once they have acquired them, and this requires occupancy rights and the implementation of measures aimed at regulating and slowing down gentrification. Moreover, when residents belong to already disadvantaged groups, more significant anti-gentrification measures can be implemented in order to prevent injustices from being compounded. (shrink)

The task of tracking a small number (about four or five) visual targets within a larger set of identical items, each of which moves randomly and independently, has been used extensively to study object-based attention. Analysis of this multiple object tracking (MOT) task shows that it logically entails solving the correspondence problem for each target over time, and thus that the individuality of each of the targets must be tracked. This suggests that when successfully tracking objects, observers must also (...) keep track of them as unique individuals. Yet in the present studies we show that observers are poor at recalling the identity of successfully tracked objects (as specified by a unique identifier associated with each target, such as a number or starting location). Studies also show that the identity of targets tends to be lost when they come close together and that this tendency is greater between pairs of targets than between targets and nontargets. The significance of this finding in relation to the multiple object tracking paradigm is discussed. (shrink)

Given the diverse conceptualisations used in the measurement of organisational value congruence (OVC), the purpose of this paper is to propose an integrated typology of measurement criteria — as a methodological and measurement guideline — that can be employed in operationalising the measurement of OVC. Based on a review of over forty empirical articles, this typology proposes a path forward to operationalise the measurement of OVC by selecting from the proposed criteria and alternative dimensions to match the specific aims of (...) researchers more comprehensively. The typology thus proposed identifies six key criteria and 12 dimensions therein. It further presents how different combinations of alternative dimensions in measuring OVC are used and can be used to best suit different objectives of researchers. As a concept matrix, this typology would specifically be useful for future researchers to identify how best to measure OVC to match their specific study objectives and facilitate rational comparison of OVC studies, permitting sensible knowledge sharing. Further, this typology can be extended to locate the best possible combinations for operationalising the measurement of OVC for future research. (shrink)

Issues of identity and reduction have monopolized much of the philosopher of mind’s time over the past several decades. Interestingly, while investigations of these topics have proceeded at a steady rate, the motivations for doing so have shifted. When the early identity theorists, e.g. U. T. Place ( 1956 ), Herbert Feigl ( 1958 ), and J. J. C. Smart ( 1959 , 1961 ), fi rst gave voice to the idea that mental events might be identical to brain processes, (...) they had as their intended foil the view that minds are immaterial substances. But very few philosophers of mind today take this proposal seriously. Why, then, the continued interest in identity and reduction? Th e concern, as philosophers like Hilary Putnam and Jerry Fodor have expressed it, is that a victory for identity or reduction is a defeat for psychology. For if minds are physical, or if mental events are physical events, then psychologists might as well disassemble their laboratories, making room for the neuroscientists and molecular biologists who are in a better position to explain those phenomena once misdescribed as “psychological.” Th e worry nowadays is not that locating thought in immaterial souls will make psychology intractable, but that locating thoughts in material brains will make it otiose.

We previously reported that in the Multiple Object Tracking (MOT) task, which requires tracking several identical targets moving unpredictably among identical nontargets, the nontargets appear to be inhibited, as measured by a probe-dot detection method. The inhibition appears to be local to nontargets and does not extend to the space between objects – dropping off very rapidly away from targets and nontargets. In the present three experiments we show that (1) nontargets that are identical to targets but remain in (...) a fixed location are not inhibited and (2) moving objects that have a different shape from targets are inhibited as much as same-shape nontargets, and (3) nontargets that are on a different depth plane and so are easily filtered out are not inhibited. This is consistent with a taskdependent view of item inhibition wherein nontargets are inhibited if (and only if) they are likely to be mistaken for targets. (shrink)

In the case of ventriloquism, seeing the movement of the ventriloquist dummy’s mouth changes your experience of the auditory location of the vocals. Some have argued that cases like ventriloquism provide evidence for the view that at least some of the content of perception is fundamentally multimodal. In the ventriloquism case, this would mean your experience has constitutively audio-visual content (not just a conjunction of an audio content and visual content). In this paper, I argue that cases like ventriloquism (...) do not in fact warrant that conclusion. I then try to make sense of crossmodal cases without appealing to fundamentally multimodal content.

Duhem's and Quine's holistic theses, when properly understood, allow methodologically responsible ways of resolving a conflict between a theoretical system and experience; they only deny the possibility of doing it in an epistemically persuasive way. By developing a "string" model of scientific tests I argue that the pattern of interaction between the elements of a theoretical system arising in response to multiple adverse data can be helpful in locating a "weak spot" in it. Combining this model with anti-holistic arguments (...) of Popper, Greenwood, and Lakatos significantly reinforces their joint power. (shrink)

Recent work suggests that DNA replication origins are regulated by the number of multiple mini‐chromosome maintenance (MCM) complexes loaded. Origins are defined by the loading of MCM – the replicative helicase which initiates DNA replication and replication kinetics determined by origin's location and firing times. However, activation of MCM is heterogeneous; different origins firing at different times in different cells. Also, more MCMs are loaded in G1 than are used in S phase. These aspects of MCM biology are (...) explained by the observation that multiple MCMs are loaded at origins. Having more MCMs at early origins makes them more likely to fire, effecting differences in origin efficiency that define replication timing. Nonetheless, multiple MCM loading raises new questions, such as how they are loaded, where these MCMs reside at origins, and how their presence affects replication timing. In this review, we address these questions and discuss future avenues of research. (shrink)

Standard theories in mereotopology focus on relations of parthood and connection among spatial or spatio-temporal regions. Objects or processes which might be located in such regions are not normally directly treated in such theories. At best, they are simulated via appeal to distributions of attributes across the regions occupied or by functions from times to regions. The present paper offers a richer framework, in which it is possible to represent directly the relations between entities of various types at different levels, (...) including both objects and the regions they occupy. What results is a layered mereotopology, a theory which can handle multiple layers (analogous to the layers of a lasagna) of spatially or spatiotemporally coincident but mereologically non-overlapping entities.

This paper challenges the view that there is one medical model of disability monolithically and oppressively imposed on disabled people. Because the presence of disability may be ambiguous in any given case, multiple actors, lay and professional, may invoke particular medical models of disability and advance competing claims about an individual’s disabilities and related needs. The literature for parents of disabled children is seen as a resource on which parents can draw in making claims about their children’s disabilities and (...) disability-related needs. Particular attention is given to the assumptions that this literature makes about the identity, resources and dispositions of the audience. Ultimately, these assumptions favor disability claims made by white, highly educated, upper-income parents. (shrink)

The notion that visual attention can operate over visual objects in addition to spatial locations has recently received much empirical support, but there has been relatively little empirical consideration of what can count as an `object' in the ®rst place. We have investi- gated this question in the context of the multiple object tracking paradigm, in which subjects must track a number of independently and unpredictably moving identical items in a ®eld of identical distractors. What types of feature clusters (...) can be tracked in this manner? In other words, what counts as an `object' in this task? We investigated this question with a technique we call target merging: we alter tracking displays so that distinct target and distractor loca- tions appear perceptually to be parts of the same object by merging pairs of items (one target with one distractor) in various ways ± for example, by connecting item locations with a simple line segment, by drawing the convex hull of the two items, and so forth. The data show that target merging makes the tracking task far more dif®cult to varying degrees depending on exactly how the items are merged. The effect is perceptually salient, involving in some conditions a total destruction of subjects' capacity to track multiple items. These studies provide strong evidence for the object-based nature of tracking, con®rming that in some contexts attention must be allocated to objects rather than arbitrary collections of features. In addition, the results begin to reveal the types of spatially organized scene components that can be independently attended as a function of properties such as connectedness, part struc- ture, and other types of perceptual grouping. q 2001 Elsevier Science B.V.

Normally this is not how we think material objects work. I, for example, am a material object that is located in multiple places: this place to my left where my left arm is, and this, distinct, place to my right, where my right arm is. But I am only partially located in each place. My left arm is a part of me that fills exactly the place to my left, and my right arm is a distinct part of me (...) that fills exactly the place to my right. I am located in multiple places by virtue of having distinct parts in those places. So entension is not happening to me — I do not entend. (shrink)

Point-of-interest recommendations are a popular form of personalized service in which users share their POI location and related content with their contacts in location-based social networks. The similarity and relatedness between users of the same POI type are frequently used for trajectory retrieval, but most of the existing works rely on the explicit characteristics from all users’ check-in records without considering individual activities. We propose a POI recommendation method that attempts to optimally recommend POI types to serve (...) class='Hi'>multiple users. The proposed method aims to predict destination POIs of a user and search for similar users of the same regions of interest, thus optimizing the user acceptance rate for each recommendation. The proposed method also employs the variable-order Markov model to determine the distribution of a user’s POIs based on his or her travel histories in LBSNs. To further enhance the user’s experience, we also apply linear discriminant analysis to cluster the topics related to “Travel” and connect to users with social links or similar interests. The probability of POIs based on users’ historical trip data and interests in the same topics can be calculated. The system then provides a list of the recommended destination POIs ranked by their probabilities. We demonstrate that our work outperforms collaborative-filtering-based and other methods using two real-world datasets from New York City. Experimental results show that the proposed method is better than other models in terms of both accuracy and recall. The proposed POI recommendation algorithms can be deployed in certain online transportation systems and can serve over 100,000 users. (shrink)

We present a computational model of multiple-object tracking that makes trial-level predictions about the allocation of visual attention and the effect of this allocation on observers' ability to track multiple objects simultaneously. This model follows the intuition that increased attention to a location increases the spatial resolution of its internal representation. Using a combination of empirical and computational experiments, we demonstrate the existence of a tight coupling between cognitive and perceptual resources in this task: Low-level tracking of (...) objects generates bottom-up predictions of error likelihood, and high-level attention allocation selectively reduces error probabilities in attended locations while increasing it at non-attended locations. Whereas earlier models of multiple-object tracking have predicted the big picture relationship between stimulus complexity and response accuracy, our approach makes accurate predictions of both the macro-scale effect of target number and velocity on tracking difficulty and micro-scale variations in difficulty across individual trials and targets arising from the idiosyncratic within-trial interactions of targets and distractors.

The term ‘locked-in’ syndrome (LIS) describes a medical condition in which persons concerned are severely paralyzed and at the same time fully conscious and awake. The resulting anarthria makes it impossible for these patients to naturally communicate, which results in diagnostic as well as serious practical and ethical problems. Therefore, developing alternative, muscle-independent communication means is of prime importance. Such communication means can be realized via brain–computer interfaces (BCIs) circumventing the muscular system by using brain signals associated with preserved cognitive, (...) sensory, and emotional brain functions. Primarily, BCIs based on electrophysiological measures have been developed and applied with remarkable success. Recently, also blood flow–based neuroimaging methods, such as functional magnetic resonance imaging (fMRI) and functional near-infrared spectroscopy (fNIRS), have been explored in this context. After reviewing recent literature on the development of especially hemodynamically based BCIs, we introduce a highly reliable and easy-to-apply communication procedure that enables untrained participants to motor-independently and relatively effortlessly answer multiple-choice questions based on intentionally generated single-trial fMRI signals that can be decoded online. Our technique takes advantage of the participants’ capability to voluntarily influence certain spatio-temporal aspects of the blood oxygenation level–dependent (BOLD) signal: source location (by using different mental tasks), signal onset and offset. We show that healthy participants are capable of hemodynamically encoding at least four distinct information units on a single-trial level without extensive pretraining and with little effort. Moreover, realtime data analysis based on simple multi-filter correlations allows for automated answer decoding with a high accuracy (94.9%) demonstrating the robustness of the presented method..

In Being in Time I articulate and defend a theory of diachronic identity based on a new account of the relation between objects and time. Traditionally, the relation between objects and time has been considered to be a direct one, analogous to the one they have with space, and accordingly called location. In my dissertation, I argue that this locative approach is metaphysically problematic insofar as it commits us to questionable consequences about the nature of objects or about the (...) metaphysics of location. In particular, the locative approach, depending on how it is specified, requires that objects do not persist, have multiple exact locations, divide into temporal parts, or are extended simples. In place of this locative approach, and drawing from an analysis of our temporal semantics, I put forward an account of the relation between objects and time – transcendentism, to give it a name – according to which this relation is indirect, and has to be analysed in terms of the events in which objects participate. Accordingly, for a object to exist at a time is for it to participate in an event which is located at that time. As such, transcendentism is not yet a theory of persistence – insofar as objects may be in time without persisting, i.e. by existing at an instant alone –. Transcendentism is an open option for every kind of persistence theorist – be one an endurantist, a perdurantist, or an exdurantist –. However, the combination of transcendentism and endurantism may reveal itself to be a semantically grounded and metaphysically fruitful choice. Semantically grounded, insofar as the analysis of our temporal semantics speaks against the locative approach and in favour of endurantism. Metaphysically fruitful, insofar as it allows us to frame a theory of persistence that avoids all questionable consequences mentioned before – a theory according to which objects persist without having temporal parts and without being extended simples or multilocated entities. The dissertation consists of four self-standing chapters in which (i) I systematize and highlight the problematicity of the locative approach, (ii) I put forward and articulate the transcendentist alternative, (iii) I develop a suitable metaphysics of events, and (iv) I reply to five objections that have been moved against the view both in official communications and in print.

One specific instantiation of the storm-and-stress view of adolescence is the idea that “normal” adolescence involves high-risk substance use behaviors. However, although uptake of some substance use behaviors is more common during adolescence than other life stages, it is clear that not all adolescents engage in risky substance use—and among those who do, there is much variation in emotional, behavioral, and contextual precursors of this behavior. One such set of predictors forms the internalizing pathway to substance use disorder, whereby internalizing (...) symptoms in childhood such as negative affect and anxiety set off a chain of consequences culminating in high-risk substance use in late adolescence. However, findings linking internalizing symptoms to substance use are mixed, and it is clear that this link varies across adolescents and contexts. One heretofore unanswered question is whether and how geographic location, specifically whether the adolescent lives in an urban or rural location, moderates this link. The current report is a secondary analysis of data from the Longitudinal Study of Australian Children, in which we examined the link between internalizing symptoms in childhood and initiation of substance use through age 19. Using a multiple event process survival mixture model, we identified three trajectories of substance use initiation in adolescence: one characterized by near-complete abstinence until late adolescence, another by earlier initiation of alcohol, nicotine, and cannabis, and another by early initiation of these substances and later initiation of more hazardous drugs such as cocaine and methamphetamine. Although childhood externalizing symptoms increased the risk of being in the second or third class, internalizing symptoms decreased risk when rural and non-rural adolescents were considered together. Few effects of rurality were found, but the negative relationship between internalizing at age 10 and high-risk substance use was only observed among non-rural adolescents. This finding, which was inconsistent with our initial predictions that rurality might confer higher risk for substance use, instead suggests a potentially protective effect of internalizing symptoms for engagement in risky substance use which may differ based on an adolescent’s geographical context.

Using the Multiple Object Tracking (MOT) task, Pylyshyn & Leonard (VSS03) showed that a small brief probe dot was detected more poorly when it occurred on a nontarget than when it occurred either on a target or in the space between items, suggesting that moving nontarget items were inhibited. Here we generalize this finding by comparing probe detection performance against a baseline condition in which no tracking was required. We examined both a baseline condition in which objects did not (...) move and one in which they moved exactly as in the probe detection task, but without tracking. Detection in the nonmoving control was essentially error-free, but probe detection performance in the moving (non-tracking) control task did depend on the probe location. Nonetheless, the findings reported earlier (worse detection on nontargets than anywhere else) remained after we took account of the baseline performance (using several different baseline comparison methods). Using this new baseline-control method we also showed that inhibition does not spread more than about 1.3 degrees of visual angle from the nontargets as the latter move during a tracking trial. In the present report we also describe some preliminary studies of conditions under which enhancement of targets, as well as inhibition of nontargets, may be obtained. Increasing the number and type of nontargets appeared to improve the detection of probes on targets, relative to baseline. However, we failed to find evidence that potentially distracting nontarget objects were inhibited more than clearly task-irrelevant objects, as would be expected if inhibition were a top-down process applied in order to improve performance on the main tracking task. For example, using the comparison with its matching baseline, we showed that task-irrelevant stationary items (which are never confused with targets in the tracking task) appeared to be inhibited even more than nontargets.

Some colors are compound colors, in the sense that they look complex: orange, violet, green..., by contrast to elemental colors like yellow or blue. In the chapter 3 of his Unterschungen zur Sinnespsychologie, Brentano purports to reconcile the claim that some colors are indeed intrinsically composed of others, with the claim that colors are impenetrable with respect to each other. His solution: phenomenal green is like a chessboard of blue and yellow squares. Only, such squares are so small that we (...) cannot discriminate between their location in perception. Consequently we get the impression of an homogeneous green extent. After having presented Brentano's solution, we argued that it is hardly compatible with Brentano's own conception of descriptive psychology, to the extent that it introduces in-existent objects (small yellow and blue squares), which cannot be perceived. We propose another solution to Brentano's puzzle, more in tune with his own assumptions, or so we argue. According to it, the yellow and the blue are in the green without being spatially in the green. A green extent has yellow and blue components, but these are not spatial components. This solution reconciles impenetrability (since the component colors are not localized) with the reality of compounds color. Besides, it has the advantage of taking the phenomenology of compounds colors, as Brentano's describes it, to the letter. Compound colors are what they seem: complex but not spatially complex.

Endogenous and exogenous processes of attention have been inferred with different types of precues used in allocation of attention to a target location. In the present research, a comparison was made between the typical peripheral single-element precue (SEP), a central precue, and a multiple-element precue (MEP) in order to further understanding of the processes involved in allocation of attention. Two precues were used on each trial in these experiments. An abrupt-onset precue appeared with an SEP, an MEP, or (...) a central precue and was followed 50 or 300 ms later by a screen containing a target and two distractor characters. The abrupt-onset precue and the other precue each could be valid or invalid in indicating the location of the target, as in the study by Juola, Koshino, and Warner (1995). Response times to the targets showed that validity effects of the abrupt-onset precue and the MEP or central precue were additive, whereas those of the abrupt-onset precue and the SEP were interactive. These data suggest that, like a central precue, an MEP is an endogenous precue that guides conscious control of attention and has its attentional effects at a different processing level from an SEP, which is an exogenous precue and may compete for attentional resources with an abrupt-onset precue.

This article deals with the complex personality and legacy of a mysterious saint known both as a Sufī (Ḥājji Ratan) and a Nāth Yogī (Ratannāth) and links his multiple identity as well as the religious movement originated from him, to the specific cultural context of the former North-West Indian provinces. The first part is devoted to Ratan in the Nāth Yogī tradition, the second to his many facets in the Muslim tradition, in connection with his dargāh in the Panjabi (...) town of Bhatinda. The third and main part explores a particular movement, the Har Śri Nāth tradition. Presently centered around a “ dargāh mandir ” in Delhi, this movement, with its two branches issued from Ratan and from his “son” Kāyānāth, was rooted in what is now Pakistan. The influence of location and history has led to many peculiarities which lead us to stress the blurred boundaries between Islam and Hinduism and the essential part played by charismatic figures in the construction of religious identities.

Wheat is the most imperative crop for man feeding and is planted in numerous countries under rainfed conditions in semiarid zones. It is necessary for decision-makers and governments to predict the yield of rainfed wheat before harvest and to determine the effect of the major factors on it. Different methods have been suggested for forecasting yield with various levels of accuracy. One of these approaches is the statistical regression model, which is simple and applicable for regions with scarce data available. (...) Since the weather is the most important factor affecting the production of wheat, particularly in rainfed cultivation, regression models using weather parameters are very common. However, the coefficients of these models are location based and should be determined locally. Therefore, in this research, backward multiple linear regression technique based on relative importance metrics was used to determine the most important effective weather parameters on rainfed wheat productions in Fars Province, south of Iran, during 2006–2013. The influence of each parameter in the final model was analyzed using the values of LMG relative importance metric. The result indicated that sunshine hours had the biggest LMG and, therefore, was the most effective parameter. Also, among the other considered parameters, rainy days, minimum relative humidity, and average relative humidity with LMG values of 21.97%, 21.69%, and 21.62%, respectively, had the most effects on rainfed wheat yield in the studied area. All parameters except for the sunshine hours positively affected rainfed wheat yield. The most important reason for the significance of these parameters can be the prevailing dry and semidry climate in the southern areas of Iran. The proposed model for determination of weather parameters effects on rainfed wheat could be a great guidance and aid for different stakeholders such as farmers, decision-makers, and governments.

What is human nature? How is language related to thought -- and should the connection be investigated socially or scientifically? Is external reality coherent or fragmented? What are the foundations of rationality, and how trustworthy are they? Such questions have bedevilled thinkers for millennia. Contemporary scholars have harnessed enormous resources to find answers, yet their inquiry is invariably constrained by the tunnel vision of academic specialisation. This issue of The Dolphin seeks to establish common ground among the disciplines examining the (...) mind-brain continuum. Among those meeting the editors' challenge to think outside the disciplinary box are Noam Chomsky, John Searle and Steven Pinker, as well as a dozen others from the fields of neuroscience, linguistics, philosophy, cognitive science, English, computer science and ethnography. The implicit framework that results should help researchers in all fields locate the diversity of human knowing within a joint ontological perspective. (shrink)

Summary Historical scholars have recently turned their attention to local communities, resulting in a lively debate about the role of regions and provinces in Western Europe. This has quite predictably led many to question this resurgence of local identities in order to discover the cultural roots and the geographical boundaries of these identities and their interaction with the formation of nation-states in the literary, artistic and political practices of the past two centuries. This article provides an introduction to one specific (...) transnational intellectual network, the Guild of Saint Thomas and Saint Luke, which in the latter half of the nineteenth century served as a forum for the different local identities which were influential in the Gothic (and Catholic) Revival of the Low Countries. The interaction among the most influential members during the annual excursions of the Guild and the choice for the locations of these meetings resulted in different ideological discourses about the position and the borders of ‘Christian art’ in the Low Countries. Due to both internal and external influences these discourses very soon integrated into the national frame, making the definition of a potentially common style for the whole area impossible. The analysis is based on existing literature on regionalism and the Neo-Gothic Revival, and on archive material concerning the first meetings of the Guild. The above-mentioned observations offer the opportunity to underline the peculiarity of transnational permanent networks composed by a fluctuating number of participants and to stimulate debate about the applicability of this example to other geo-cultural contexts.

This essay details the manifestation of the artwork Home Ground, including its subsequent iterations, to explore how an artwork might function as both an expression and extension of narratives associated with its author, Steven Rhall. This exploration begins with a consideration of the ways in which various contextual frameworks inform ‘subjective decisions’, for example, coloniality, and process-led making. I identify as a Taungurung man but I live in a colonised society, experiencing cultures tied to each positionality in the contradictory, complex (...) overlapping contexts of everyday life. The essay takes interest in how these frameworks also shift as the iterative work unfolds in new temporal and geographical locations, ultimately emphasising the interrelationship between author, narrative, and wider contextual frameworks. The essay then moves to consider how the narratives spurred in the art-making process continue to evolve in the author’s absence and in relationship to subsequent audiences. The essay posits itself as a metanarrative in that it acts as an extension of the artwork it is discussing. As such, the essay employs the same photographic images that form the material nexus of Home Ground, thereby further extending the narratives contained in them via the medium of this written text itself.

Likert scales are useful for collecting data on attitudes and perceptions from large samples of people. In particular, they have become a well-established tool in soundscape studies for conducting in situ surveys to determine how people experience urban public spaces. However, it is still unclear whether the metrics of the scales are consistently interpreted during a typical assessment task. The current work aims at identifying some general trends in the interpretation of Likert scale metrics and introducing a procedure for the (...) derivation of metric corrections by analyzing a case study dataset of 984 soundscape assessments across 11 urban locations in London. According to ISO/TS 12913-2:2018, soundscapes can be assessed through the scaling of 8 dimensions: pleasant, annoying, vibrant, monotonous, eventful, uneventful, calm, and chaotic. The hypothesis underlying this study is that a link exists between correlations across the percentage of assessments falling in each Likert scale category and a dilation/compression factor affecting the interpretation of the scales metric. The outcome of this metric correction value derivation is introduced for soundscape, and a new projection of the London soundscapes according to the corrected circumplex space is compared with the initial ISO circumplex space. The overall results show a general non-equidistant interpretation of the scales, particularly on the vibrant-monotonous direction. The implications of this correction have been demonstrated through a Linear Ridge Classifier task for predicting the London soundscape responses using objective acoustic parameters, which shows significant improvement when applied to the corrected data. The results suggest that the corrected values account for the non-equidistant interpretation of the Likert metrics, thereby allowing mathematical operations to be viable when applied to the data.

Presence as ordinarily understood requires spatio-temporal proximity. If however Christ’s presence in the Eucharist is understood as spatio-temporal proximity it would take a miracle to secure multiple location and an additional miracle to cover it up so that the presence of Christ wherever the Eucharist was celebrated made no empirical difference. And, while multiple location is logically possible, such metaphysical miracles—miracles of distinction without difference, which have no empirical import—are problematic. I propose an account of Eucharist (...) according to which Christ is indeed really and objectively present in the religiously required sense, without benefit of metaphysical miracles. (shrink)
