Are emotions perceptual experiences of value?
A number of emotion theorists hold that emotions are perceptions of value. In this paper I say why they are wrong. I claim that in the case of emotion there is nothing that can provide the perceptual modality that is needed if the perceptual theory is to succeed (where by 'perceptual modality' I mean the particular manner in which something is perceived). I argue that the five sensory modalities are not possible candidates for providing us with 'emotional perception'. But I also say why the usual candidate offered - namely feeling or affectivity - does not give us the sought-after perceptual modality. I conclude that as there seems to be nothing else that can provide the needed perceptual modality, we should reject the perceptual theory of emotion. © 2012 Blackwell Publishing Ltd
Evaluating medico-legal decisional competency criteria
In this paper I get clearer on the considerations that ought to inform the evaluation and development of medico-legal competency criteria-where this is taken to be a question regarding the abilities that ought to be needed for a patient to be found competent in medico-legal contexts. In the "Decisional Competency in Medico-Legal Contexts" section I explore how the question regarding the abilities that ought to be needed for decisional competence is to be interpreted. I begin by considering an interpretation that takes the question to be asking about the abilities needed to satisfy an idealized view of competent decision-making, according to which decisional competency is a matter of possessing those abilities or attributes that are needed to engage in good or effective or, perhaps, substantially autonomous or rational decision-making. The view has some plausibility-it accords with the way decisional competency is understood in a number of everyday contexts-but fails as an interpretation of the question regarding the abilities that should be needed for decisional competence in medico-legal contexts. Nevertheless, consideration of why it is mistaken suggests a more accurate interpretation and points the way in which the question regarding the evaluation of medico-legal competency criteria is to be answered. Building on other scholarly work in the area, I outline in the "Primary and Secondary Requirements" section several requirements that decisional competence criteria ought to satisfy. Then, in the "Applying the Framework" section, I say something about the extent to which medico-legal competency criteria, as well as some models of decisional competency proposed in the academic literature, fulfil those requirements
Simultaneous Phase Separation and Pattern Formation in Chiral Active Mixtures
Chiral active particles, or self-propelled circle swimmers, from sperm cells
to asymmetric Janus colloids, form a rich set of patterns, which are different
from those seen in linear swimmers. Such patterns have mainly been explored for
identical circle swimmers, while real-world circle swimmers, typically possess
a frequency distribution. Here we show that even the simplest mixture of
(velocity-aligning) circle swimmers with two different frequencies, hosts a
complex world of superstructures: The most remarkable example comprises a
microflock pattern, formed in one species, while the other species phase
separates and forms a macrocluster, coexisting with a gas phase. Here, one
species microphase-separates and selects a characteristic length scale, whereas
the other one macrophase separates and selects a density. A second notable
example, here occurring in an isotropic system, are patterns comprising two
different characteristic length scales, which are controllable via frequency
and swimming speed of the individual particles
The Rotating Vicsek Model: Pattern Formation and Enhanced Flocking in Chiral Active Matter
We generalize the Vicsek model to describe the collective behaviour of polar
circle swimmers with local alignment interactions. While the phase transition
leading to collective motion in 2D (flocking) occurs at the same interaction to
noise ratio as for linear swimmers, as we show, circular motion enhances the
polarization in the ordered phase (enhanced flocking) and induces secondary
instabilities leading to structure formation. Slow rotations result in phase
separation whereas fast rotations generate patterns which consist of phase
synchronized microflocks of controllable self-limited size. Our results defy
the viewpoint that monofrequent rotations form a rather trivial extension of
the Vicsek model and establish a generic route to pattern formation in chiral
active matter with possible applications to control coarsening and to design
rotating microflocks.Comment: Contains a Supplementary Materia
TRACEABILITY IN STOCK MANAGEMENT SYSTEMS
This paper presents traceability of a product if we are using a stock management system which uses FIFO or LIFO discharging methods. In the first part there is a little presentation regarding the four types of inputs and outputs and the side effect to thetraceability, stock, management
Micro-flock patterns and macro-clusters in chiral active Brownian disks
Chiral active particles (or self-propelled circle swimmers) feature a rich
collective behavior, comprising rotating macro-clusters and micro-flock
patterns which consist of phase-synchronized rotating clusters with a
characteristic self-limited size. These patterns emerge from the competition of
alignment interactions and rotations suggesting that they might occur
generically in many chiral active matter systems. However, although excluded
volume interactions occur naturally among typical circle swimmers, it is not
yet clear if macro-clusters and micro-flock patterns survive their presence.
The present work shows that both types of pattern do survive but feature
strongly enhance fluctuations regarding the size and shape of the individual
clusters. Despite these fluctuations, we find that the average micro-flock size
still follows the same characteristic scaling law as in the absence of excluded
volume interactions, i.e. micro-flock sizes scale linearly with the
single-swimmer radius
