The epistemological status of semantic components of ethnosemantics is investigated with reference to Wittgenstein's definition of the meaning of a word as its use in language. Semantic components, like the intension of words in logistic philosophy, constitute the conditions which must pertain to objects in order that they are denoted by particular words. "Componential meaning" is determined to be another form of "unitary meaning" and hence subject to the same critical arguments made by Wittgenstein against the latter's three fundamental types: (...) (1) meanings are objects, (2) meanings are images, and (3) meanings are feelings and mental experiences. A rebuttal to D'Andrade's labeling rule objection to the usage theory of meaning is presented.

This article presents a qualitative case study that explores how faculty and administrators at one community college conceptualized and experienced academic community within their institution and how that conceptualization helped shape the part-time faculty work environment. Using a combined framework of academic community and care ethics, this study utilizes data from 55 interviews with full-time and part-time faculty and administrative leaders from a large community college. Findings from this study indicate that defining membership, a sense of belonging, and shared mission (...) and goals are key components to their understanding of academic community. From these three components, the study found that when participants included adjunct faculty as members of their academic community, they also reported a sense of responsibility or obligation to supporting them.

In the Prologue to the third book of Gargantua, Francois Rabelais compares his own predicament to that of the philosopher Diogenes of Sinope during the seige of Cornith. “I held it not a little disgraceful”, he confides, “to be only an idle spectator of so many valorous, eloquent and warlike persons, who in the view and sight of all Europe act this notable interlude or tragi-comedy, and not exert myself and contribute thereunto this nothing, my all, which remained for me (...) to do”.

In one of its numerous meanings “mind” has long represented, and popularly still to some extent does represent, a special non-spatial type of entity transcending and ideally complementing the world of matter. More particularly it has stood for an innate “rational faculty” characterizing men as men; an immaterial substance radically differentiating human beings from animals and by the same token serving to bind them to one another, as brothers are bound by the tie of common blood. Thus conceived, mind traditionally (...) has justified, and so strengthened, the ingenuous a priori regard and appreciation which unlearned persons extend to their fellows for the sole reason that they are human. Upon this conception of mind numerous popular doctrines of “personal dignity,” “human equality”, “individual liberty”, “freedom of conscience”, “inalienable rights”, and so forth, have been rationally grounded. And without it as an inspiration—to name but one dependent consequence—“the American dream”, which Adams describes in The Epic of America, would doubtless never have been dreamt. (shrink)

This paper is concerned with a question in metaphysics. The question is: Is the world ultimately one, or is it many? It is neither a very profound nor a very complicated question. It is, on the contrary, very simple. But despite its simplicity, it expresses the most basic of all metaphysical problems.When two metaphysical problems, A and B, are so related that the statement of B assumes an answer to A, then we may fairly infer that A is more basic (...) than B, and B less basic than A.

This paper is a study in restraint on freedom of speculation. In view of the subtlety of the subject it has seemed advisable to begin the report with a list of the presuppositions initiating and determining the study. These are as follows:1). That freedom of speculation is a prerequisite to sound mental health, in individuals as well as in large-scale social units.2). That, consequently, individual and institutional faculties are alike deficient if and insofar as they prevent or abridge such freedom.3). (...) That the same factors operating in one aspect to restrain the influence of promulgated theories operate in another aspect to inhibit the free conception and hamper the expression of speculation not so promulgated.4). That as it is the purpose of individual philosophizing to surround with coherent speculation or theory subjects of primarily individual interest, it is the purpose of institutional philosophizing similarly to invest with theory subjects of common social interest.5). That speculation in general, whether individual or institutional, is free when the prevalent tendency is for subjects of comparable interest to be accorded comparable quantities of speculation; and that when and insofar as this tendency does not prevail speculation is to that extent not free but restrained.

The medial prefrontal cortex (mPFC) has been the subject of intense interest as a locus of cognitive control. Several computational models have been proposed to account for a range of effects, including error detection, conflict monitoring, error likelihood prediction, and numerous other effects observed with single-unit neurophysiology, fMRI, and lesion studies. Here, we review the state of computational models of cognitive control and offer a new theoretical synthesis of the mPFC as signaling response–outcome predictions. This new synthesis has two interacting (...) components. The first component learns to predict the various possible outcomes of a planned action, and the second component detects discrepancies between the actual and intended responses; the detected discrepancies in turn update the outcome predictions. This single construct is consistent with a wide array of performance monitoring effects in mPFC and suggests a unifying account of the cognitive role of medial PFC in performance monitoring.

In the past two decades, reinforcement learning has become a popular framework for understanding brain function. A key component of RL models, prediction error, has been associated with neural signals throughout the brain, including subcortical nuclei, primary sensory cortices, and prefrontal cortex. Depending on the location in which activity is observed, the functional interpretation of prediction error may change: Prediction errors may reflect a discrepancy in the anticipated and actual value of reward, a signal indicating the salience or novelty of (...) a stimulus, and many other interpretations. Anterior cingulate cortex has long been recognized as a region involved in processing behavioral error, and recent computational models of the region have expanded this interpretation to include a more general role for the region in predicting likely events, broadly construed, and signaling deviations between expected and observed events. Ongoing modeling work investigating the interaction between ACC and additional regions involved in cognitive control suggests an even broader role for cingulate in computing a hierarchically structured surprise signal critical for learning models of the environment. The result is a predictive coding model of the frontal lobes, suggesting that predictive coding may be a unifying computational principle across the neocortex. (shrink)

Is consolidation needed to account for retroactive interference in free recall? Interfering mental activity during the retention interval of a memory task impairs performance, in particular if the interference occurs in temporal proximity to the encoding of the to-be-remembered information. There are at least two rival theoretical accounts of this temporal gradient of retroactive interference. The cognitive neuroscience literature has suggested neural consolidation is a pivotal factor determining item recall. According to this account, interfering activity interrupts consolidation processes that would (...) otherwise stabilize the memory representations of TBR items post-encoding. Temporal distinctiveness theory, by contrast, proposes that the retrievability of items depends on their isolation in psychological time. According to this theory, information processed after the encoding of TBR material will reduce the temporal distinctiveness of the TBR information. To test between these accounts, implementations of consolidation were added to the SIMPLE model of memory and learning. We report data from two experiments utilizing a two-list free recall paradigm. Modeling results imply that SIMPLE was able to model the data and did not benefit from the addition of consolidation. It is concluded that the temporal gradient of retroactive interference cannot be taken as evidence for memory consolidation. (shrink)

Science fiction is often held up as a particularly philosophical genre. For, beyond actualising mind-experiment-like fantasies, science fiction films also commonly toy with speculative ideas, or else engineer encounters with the strange and unknown. Denis Villeneuve's Arrival is a contemporary science fiction film that does exactly this, by introducing Lovecraft-esque tentacular aliens whose arrival on Earth heralds in a novel, but ultimately paralysing, inhuman perspective on the nature of time and reality. This article shows how this cerebral film invites viewers (...) to confront a counterintuitive model of time that at once recalls and reposes what Gilles Deleuze called a “third synthesis” of time, and that which J. M. E. McTaggart named the a-temporal “C series” of “unreal” time. We finally suggest that Arrival's a-temporal conception of the future as having already happened can function as a key to understanding the fate of humanity as a whole as we pass from the anthropocene, in which humans have...

Taking a schizoanalytic approach to audio-visual images, this article explores some of the radical potentia for deterritorialisation found within David Fincher's Fight Club (1999). The film's potential for deterritorialisation is initially located in an exploration of the film's form and content, which appear designed to interrogate and transcend a series of false binaries between mind and body, inside and outside, male and female. Paying attention to the construction of photorealistic digital spaces and composited images, we examine the actual (and possible) (...) ways viewers relate to the film, both during and after screenings. Recognising the film as an affective force performing within our world, we also investigate some of the real-world effects the film catalysed. Finally, we propose that schizoanalysis, when applied to a Hollywood film, suggests that Deleuze underestimated the deterritorialising potential of contemporary, special effects-driven cinema. If schizoanalysis has thus been reterritorialised by mainstream products, we argue that new, ‘post-Deleuzian’ lines of flight are required to disrupt this ‘de-re-territorialisation’. (shrink)

Before the development of the nuclear shell model estimates of the strength of the nuclear spin-orbit interaction varied widely. Wheeler was the first to conclude that the nuclear spin-orbit interaction produces splittings of several MeV. This conclusion appeared, however, to be inconsistent with some experimental results that later turned out to be faulty.

A cut or crush injury to a peripheral nerve results in the degeneration of that portion of the axon isolated from the cell body. The rapid degeneration of this distal segment was for many years believed to be a process intrinsic to the nerve. It was believed that Schwann cells both phagocytosed degenerating axons and myelin sheaths and also provided growth factors to promote regeneration of the damaged axons. In recent years, it has become apparent that the degenerating distal segment (...) is invaded by monocytes from the blood. We will review the evidence that these recruited macrophages play a role in both degeneration and regeneration of peripheral nerve axons after injury and consider whether the slow degeneration and poor monocyte recruitment in the central nervous system may contribute to the poor regeneration there.

A dual referent approach to colour theory maintains that colour names have two intended, equally legitimate referents. For example, one might argue that ‘red’ refers both to red appearances or qualia, and also to the way red objects reflect light, the spectral surface reflectance properties of red things. I argue that normal cases of perceptual relativity can be used to support a dual referent approach, yielding an understanding of colour whose natural extension includes abnormal cases of perceptual relativity. This contrasts (...) with Peacocke’s multi-referent view, according to which such abnormal cases force us to introduce a wholly distinct kind of colour experience. I also argue that the two uses of colour names, arising from their two referents, have different extensions, even in normal perceptual circumstances, a consequence which conflicts with the heart of Rosenthal’s dual referent view.
