    2018 Fall.Includes bibliographical references.Growth in the older population will increase the overall impact of age-related neurological disorders. Aging and neurological conditions share features such as impaired motor function and physical dysfunction including reduced muscle strength and power, slowness of movement, increased movement variability and balance dysfunction. Successful performance of daily activities and maintenance of mobility is key to independence and quality of life. Therefore, tracking changes in physical function is critical in gauging quality of life. However truly quantitative measures of physical capacity often require the use of expensive, lab-based equipment. Smart devices contain sensitive tri-axial accelerometers and gyroscopes that measure acceleration and rotation and offer a more cost-effective, portable yet still quantitative means of physical assessment. The purpose is to describe an iPod Touch-instrumented test battery designed to assess features of physical and motor function often shared by normal aging and age-related movement disorders. We have been assessing the correlation between measures taken from expensive lab devices and the iPod Touch smart device for a variety of movements. We developed and tested a multi-item smart device-based battery of motor tasks that addresses motor variability, slowness and postural instability across a range of young, healthy college students. By changing the location of the device we can assess upper and lower limb movement speed and power, hand tremor, or postural control. We have also used previously validated lab devices concurrently with the smart device, which allows us to correlate the results between devices to assess the extent of the association between devices. Outcomes such as peak acceleration and variability of movements can be obtained. Generally, the smart device demonstrated strong correlations with the lab grade sensors for all motor tasks. Furthermore, the smart device was also correlated with the accelerometer across a large range of speed and variability. Strong correlations were seen in ballistic arm and leg tasks, tremor, and postural control assessments. This finding suggests that the smart device can sufficiently assess a broad range of functional capacity. This battery can then be used to study populations exhibiting motor impairment, ranging from older adults, to neurological patients. Using the sensors on the smart device, this testing can be administered remotely and inexpensively by non-experts, providing cost-effective, mobile, user- and patient-friendly physical function testing. More importantly, accessibility of testing is increased while retaining quantitative precision. This should aid in quantifying disease progression and response to pharmacological or exercise/rehabilitative intervention, with the goal of improved function and quality of life in those with impairment

    Transgenic expression of the dicotyledonous pattern recognition receptor EFR in rice leads to ligand-dependent activation of defense responses

    Plant plasma membrane localized pattern recognition receptors (PRRs) detect extracellular pathogen-associated molecules. PRRs such as Arabidopsis EFR and rice XA21 are taxonomically restricted and are absent from most plant genomes. Here we show that rice plants expressing EFR or the chimeric receptor EFR::XA21, containing the EFR ectodomain and the XA21 intracellular domain, sense both Escherichia coli- and Xanthomonas oryzae pv. oryzae (Xoo)-derived elf18 peptides at sub-nanomolar concentrations. Treatment of EFR and EFR::XA21 rice leaf tissue with elf18 leads to MAP kinase activation, reactive oxygen production and defense gene expression. Although expression of EFR does not lead to robust enhanced resistance to fully virulent Xoo isolates, it does lead to quantitatively enhanced resistance to weakly virulent Xoo isolates. EFR interacts with OsSERK2 and the XA21 binding protein 24 (XB24), two key components of the rice XA21-mediated immune response. Rice-EFR plants silenced for OsSERK2, or overexpressing rice XB24 are compromised in elf18-induced reactive oxygen production and defense gene expression indicating that these proteins are also important for EFR-mediated signaling in transgenic rice. Taken together, our results demonstrate the potential feasibility of enhancing disease resistance in rice and possibly other monocotyledonous crop species by expression of dicotyledonous PRRs. Our results also suggest that Arabidopsis EFR utilizes at least a subset of the known endogenous rice XA21 signaling components

    Towards a typology of non-state actors in ‘hybrid warfare’: proxy, auxiliary, surrogate and affiliated forces

    Get PDF
    This article presents a typology of armed non-state actors in hybrid warfare: proxy, auxiliary, surrogate and affiliated forces. By focusing on the kinetic domain of hybrid warfare, the article offers a corrective to a debate that has so far ignored variation in roles and functions of non-state actors and their relationships with states and their regular forces. As a denominator, ‘hybrid’ identifies a combination of battlespaces, types of operations—military or non-kinetic—and a blurring of actors with the scope of achieving strategic objectives by creating exploitable ambiguity. However, there has been a disproportionate focus on what hybrid war supposedly combines across battlespaces and domains (socio-political, economic, informational), at the expense of who and how. Using the Ukrainian crisis as a theory-building exercise, the article suggests a four-category schema that identifies non-state actor functions as a tool to better represent the complex franchise of violence that is found nested next to non-military operations in hybrid activity. In so doing, the article speaks to a call for better conceptualization the role of non-state violent actors in civil war, in general, and in hybrid warfare, in particular

    Exploring Web-Based University Policy Statements on Plagiarism by Research-Intensive Higher Education Institutions

    Get PDF
    Plagiarism may distress universities in the US, but there is little agreement as to exactly what constitutes plagiarism. While there is ample research on plagiarism, there is scant literature on the content of university policies regarding it. Using a systematic sample, we qualitatively analyzed 20 Carnegie-classified universities that are “Very High in Research.” This included 15 public state universities and five high-profile private universities. We uncovered highly varied and even contradictory policies at these institutions. Notable policy variations existed for verbatim plagiarism, intentional plagiarism and unauthorized student collaboration at the studied institutions. We conclude by advising that the American Association of University Professors (AAUP), the American Association of Colleges and Universities (AACU) and others confer and come to accord on the disposition of these issues

    The everyday world of bouncers: a rehabilitated role for covert ethnography

    Get PDF
    © 2018, The Author(s) 2018. The focus of this article is on the everyday world of bouncers in the night-time economy of Manchester, England. The structure of the article is to contextualise my covert passing in this demonized subculture followed by explorations of the everyday world of bouncers through the related concepts of door order and the bouncer self. A part of the article is an examination of the management of situated ‘ethical moments’ during the fieldwork and, more generally, critical reflections on emotionality, embodiment and risk-taking in ethnography. I also reflect on the retrospective and longitudinal nature of my fieldwork immersion, and both the data management challenges and possibilities this brings. Covert ethnography can be a creative part of the ethnographer’s tool kit and can provide an alternative perspective on subcultures, settings and organisations. By overly frowning upon the apparent ethical transgressions of covert research, we can stifle and censor the sociological imagination rather than enhance it. My call is for a rehabilitation of covert research
