    A Critical Evaluation Of The Trigger Point Phenomenon

    The theory of myofascial pain syndrome (MPS) caused by trigger points (TrPs) seeks to explain the phenomena of muscle pain and tenderness in the absence of evidence for local nociception. Although it lacks external validity, many practitioners have uncritically accepted the diagnosis of MPS and its system of treatment. Furthermore, rheumatologists have implicated TrPs in the pathogenesis of chronic widespread pain (fibromyalgia syndrome). We have critically examined the evidence for the existence of myofascial TrPs as putative pathological entities and for the “vicious cycles that are said to maintain them. We find that both are inventions that have no scientific basis, whether from experimental approaches that interrogate the suspect tissue or empirical approaches that assess the outcome of treatments predicated on presumed pathology. Therefore the theory of MPS caused by TrPs has been refuted. This is not to deny the existence of the clinical phenomena themselves, for which scientifically sound and logically plausible explanations based on known neurophysiological phenomena can be advanced

    How is a sense of well-being and belonging constructed in the accounts of autistic adults?

    This small-scale exploratory study sought to develop an understanding of the meaning of well-being and social belonging as represented within the narratives of adults on the autism spectrum. Employing an interpretivist approach facilitated the investigation of potential contributory factors to these lived experiences in order to inform further research regarding both this topic, and service provision for adults on the autism spectrum. The project involved a thematic analysis of issues of the magazine Asperger United (AU). Four broad main themes were identified: meeting personal needs, living with the consequences of an ‘othered’ identity, connection and recognition, and relationships and advocacy. Autistic adults reported many barriers to feeling that they belonged in a number of social spaces and the detrimental effect this had on their wellbeing. Fundamental to positive narratives of wellbeing, were feelings of connection and recognition from others and positive accepting relationships, with autistic-led spaces, particularly the Autscape conference, being frequently cited as of central significance in increasing feelings of wellbeing and belonging. This study has demonstrated a need for less focus on remediation and more on limiting the social isolation of autistic people

    Casimir forces and non-Newtonian gravitation

    The search for non-relativistic deviations from Newtonian gravitation can lead to new phenomena signalling the unification of gravity with the other fundamental interactions. Various recent theoretical frameworks indicate a possible window for non-Newtonian forces with gravitational coupling strength in the micrometre range. The major expected background in the same range is attributable to the Casimir force or variants of it if dielectric materials, rather than conducting ones, are considered. Here we review the measurements of the Casimir force performed so far in the micrometre range and how they determine constraints on non-Newtonian gravitation, also discussing the dominant sources of false signals. We also propose a geometry-independent parameterization of all data in terms of the measurement of the constant c. Any Casimir force measurement should lead, once all corrections are taken into account, to a determination of the constant c which, in order to assess the accuracy of the measurement, can be compared with its more precise value known through microscopic measurements. Although the last decade of experiments has resulted in solid demonstrations of the Casimir force, the situation is not conclusive with respect to being able to discover new physics. Future experiments and novel phenomenological analysis will be necessary to discover non-Newtonian forces or to push the window for their possible existence into regions of the parameter space which theoretically appear unnatural.Comment: Also available at http://www.iop.org/EJ/abstract/1367-2630/8/10/23

    The Copyright Term Extension Act of 1998: An Economic Analysis

    Get PDF
    This brief provides an economic analysis of the main feature of the Copyright Term Extension Act of 1998 ('CTEA'), a twenty-year extension of the copyright term for existing and future works. Taken as a whole, the authors believe that it is highly unlikely that the economic benefits from copyright extension under the CTEA outweigh the additional costs.Technology and Industry

    Vaccinia Virus Infection in Monkeys, Brazilian Amazon

    Get PDF
    To detect orthopoxvirus in the Brazilian Amazon, we conducted a serosurvey of 344 wild animals. Neutralizing antibodies against orthopoxvirus were detected by plaque-reduction neutralizing tests in 84 serum samples. Amplicons from 6 monkey samples were sequenced. These amplicons identified vaccinia virus genetically similar to strains from bovine vaccinia outbreaks in Brazil

    A dimensional summation account of polymorphous category learning

    This is the author accepted manuscript. The final version is available from Springer via the DOI in this record.Data and code availaibility: The data and code for all analyses for all experiments are available at the OSF addresses given in each Results section. The stimuli are available at the same locations.Polymorphous concepts are hard to learn, and this is perhaps surprising because they, like many natural concepts, have an overall similarity structure. However, the dimensional summation hypothesis (Milton & Wills, 2004) predicts this difficulty. It also makes a number of other predictions about polymorphous concept formation, which are tested here. In Experiment 1 we confirm the theory’s prediction that polymorphous concept formation should be facilitated by deterministic pretraining on the constituent features of the stimulus. This facilitation is relative to an equivalent amount of training on the polymorphous concept itself. In Experiments 2–4, the dimensional summation account of this single feature pretraining effect is contrasted with some other accounts, including a more general strategic account (Experiment 2), seriality of training and stimulus decomposition accounts (Experiment 3), and the role of errors (Experiment 4). The dimensional summation hypothesis provides the best account of these data. In Experiment 5, a further prediction is confirmed — the single feature pretraining effect is eliminated by a concurrent counting task. The current experiments suggest the hypothesis that natural concepts might be acquired by the deliberate serial summation of evidence. This idea has testable implications for classroom learning.Biotechnology and Biological Sciences Research Council (BBSRC

    A Conceptual Analysis of Autistic Masking: Understanding the Narrative of Stigma and the Illusion of Choice

    Get PDF
    Autistic masking is an emerging research area that focuses on understanding the conscious or unconscious suppression of natural autistic responses and adoption of alternatives across a range of domains. It is suggested that masking may relate to negative outcomes for autistic people, including late/missed diagnosis, mental health issues, burnout, and suicidality. This makes it essential to understand what masking is, and why it occurs. In this conceptual analysis, we suggest that masking is an unsurprising response to the deficit narrative and accompanying stigma that has developed around autism. We outline how classical social theory (i.e., social identity theory) can help us to understand how and why people mask by situating masking in the social context in which it develops. We draw upon the literature on stigma and marginalization to examine how masking might intersect with different aspects of identity (e.g., gender). We argue that although masking might contribute toward disparities in diagnosis, it is important that we do not impose gender norms and stereotypes by associating masking with a “female autism phenotype.” Finally we provide recommendations for future research, stressing the need for increased understanding of the different ways that autism may present in different people (e.g., internalizing and externalizing) and intersectionality. We suggest that masking is examined through a sociodevelopmental lens, taking into account factors that contribute toward the initial development of the mask and that drive its maintenance
