    This workshop for practice educators teaching social work students whilst on placement explored issues relating to failing students. Reasons why students might experience difficulties whilst on placement, early identification of problems, barriers to making a fail decision and resolution of concerns were discussed. The session considered how to evidence and articulate concerns in relation to HCPC Guidance on Conduct and Ethics for Students and the appropriate PCF levels and how to develop appropriate intervention plans, using the University's concerns process or Fitness to Practise procedures where necessary

    Barriers to Technology Adoption in the Water Treatment Industry

    This honors project focuses on barriers to technology adoption in the drinking water treatment industry. The scope of this project considers these barriers as they relate to general technology and with a specific focus on artificial intelligence (AI) and digital twins. To better understand these barriers, prior research and case studies are analyzed. The case studies include reports provided by Fontus Blue, a water treatment software provider based in Akron, Ohio. The case studies exhibit the benefits and challenges of integrating new technology, including AI systems. With the context of these case studies in mind, a survey was distributed to water system superintendents, chief operators, and others. Key results from the survey indicate that cybersecurity concerns and lack of funding are leading barriers affecting technology integration. Similar data was gathered specifically for AI adoption, and the results indicate that lack of funding, cybersecurity concerns, and lack of understanding of AI are all significant obstacles inhibiting further technology adoption. This is due in part to the relative lack of understanding of AI among respondents. The results indicate that compared to traditional technology options, there is a significant lack of understanding of what AI is and the associated benefits

    Simulation And Study Of The Stokes Vector In A Precipitating Atmosphere

    Precipitation is a dominating quantity in microwave radiometry. The large emission and scattering signals of rain and ice, respectively, introduce large contributions to the measured brightness temperature. While this allows for accurate sensing of precipitation, it also results in degraded performance when retrieving other geophysical parameters, such as near-surface ocean winds. In particular, the retrieval of wind direction requires precise knowledge of polarization, and nonspherical particles can result in a change in the polarization of incident radiation. The aim of this dissertation is to investigate the polarizing effects of precipitation in the atmosphere, including the existence of a precipitation signal in the third Stokes parameter, and compare these effects with the current sensitivities of passive wind vector retrieval algorithms. Realistic simulated precipitation profiles give hydrometeor water contents which are input into a vector radiative transfer model. Brightness temperatures are produced within the model using a reverse Monte Carlo method. Results are produced at three frequencies of interest to microwave polarimetry, 10.7 GHz, 18.7 GHz, and 37.0 GHz, for the first 3 components of the Stokes vector

    Comprehensive experimental analysis of nonlinear dynamics in an optically-injected semiconductor laser

    Get PDF
    We present the first comprehensive experimental study, to our knowledge, of the routes between nonlinear dynamics induced in a semiconductor laser under external optical injection based on an analysis of time-averaged measurements of the optical and RF spectra and phasors of real-time series of the laser output. The different means of analysis are compared for several types of routes and the benefits of each are discussed in terms of the identification and mapping of the nonlinear dynamics. Finally, the results are presented in a novel audio/video format that describes the evolution of the dynamics with the injection parameters. © 2011 Author(s)

    Division of commonty in Scotland: the use of the eighteenth- and nineteenth-century estate plans held by the Scottish Record Office in a study of historical geography.

    For many years the historical geographer in Scotland has been handicapped by the dearth of detailed source lists on which to base his research. Even great collections of manuscript plans, like those of the Scottish Record Office, lay unlisted. A major step forward occurred when the Scottish Record Office decided to employ a geographer to catalogue their collection of eighteenth and nineteenth -century estate plans which had been accumulating, from various sources, over the last century and a quarter. It was the author's good fortune to be invited to undertake this task which, through the passage of the last two and a half years, has turned into a labour of love. From this work emerged the realization that the rural landscape of lowland Scotland was of relatively recent origin and that much of it could be explained by detailed examination of plans such as I was in the process of cataloguing. The whole subject of the creation of the rural was beyond the scope of a thesis of this nature; thus I have restricted my analysis to the division of the former commonties and the influence this has had on the present landscape

    Philosophy, ideology and educational theory

    This work is concerned with the nature and scope of ideology. It begins with an examination of the relationship between theory and practice in the relatively uncontentious area of education. An analysis of different kinds of educational theory reveals the nature of the most comprehensive form of such theorising to be problematic. It is argued that a solution to this problem depends upon the solution to the wider problem of the nature of political ideology, to which the discussion therefore shifts. Existing theories of political ideology being deemed inadequate, a fresh start is made by showing how this form of theory combines the descriptive and the evaluative in a particular way and with particular logical consequences. These consequences characterise ideology as a peculiar form of ethical understanding, involving a distinctive way of thinking and having a logical structure of its own. However, these characteristics which make ideology distinctive are not inherently political, and the possibility of there being several different forms of ideology is discussed. With these conclusions it becomes possible to return to the problem of comprehensive educational theory and show that it is composed of a number of forms of ideology, some related to political ideology and some not. The work concludes with some reflections upon the extent to which ideology is an inevitable component of all thinking about human affairs

    Latitudinal distribution and mitochondrial DNA (COI) variability of Stereotydeus spp. (Acari: Prostigmata) in Victoria Land and the central Transantarctic Mountains

    We examined mitochondrial DNA (COI) variability and distribution of Stereotydeus spp. in Victoria Land and the Transantarctic Mountains, and constructed Neighbour Joining (NJ) and Maximum Likelihood (ML) phylogenetic trees using all publicly available COI sequences for the three Stereotydeus species present (S. belli, S. mollis and S. shoupi). We also included new COI sequences from Miers, Marshall and Garwood valleys in southern Victoria Land (78°S), as well as from the Darwin (79°S) and Beardmore Glacier (83°S) regions. Both NJ and ML methods produced trees which were similar in topology differing only in the placement of the single available S. belli sequence from Cape Hallett (72°S) and a S. mollis haplotype from Miers Valley. Pairwise sequence divergences among species ranged from 9.5–18.1%. NJ and ML grouped S. shoupi from the Beardmore Glacier region as sister to those from the Darwin with pairwise divergences of 8%. These individuals formed a monophyletic clade with high bootstrap support basal to S. mollis and S. belli. Based on these new data, we suggest that the distributional range of S. shoupi extends northward to Darwin Glacier and that a barrier to dispersal for Stereotydeus, and possibly other arthropods, exists immediately to the north of this area

    Screening Play: Rules, Wares, and Representations in “Realistic” Video Games

    In highlighting the apparatus as the keystone for the magic circle of video gaming, we displace players—the subject of ludology—and “text”—the subject of narratology. This is not to deny the importance of players’ agency or the meanings of texts in video gaming; rather it is to reconsider these with regard to the screening of player from played inherent in the gaming apparatus. To better understand the situation of homo ludens in these more mediated play spaces, we turn to Jacques Lacan’s account of “split” subjectivity and retread it by explaining how it may well explain the operation of a magic circle spanning three dimensions of screen-play: rules (Symbolic dimension), representations (Imaginary dimension), and wares (Real dimension). In the end, we come around to the other space of Huizinga’s theory—the connections with the non-game world—to show that the value of video game play is also found beyond the apparatus, that the experience and enjoyment of video games are affected in part by social reality and, in turn, social reality is being affected by the experience and enjoyment of video games. Arriving at this point by first theorizing the video game apparatus, however, highlights matters of video game design more so than issues of audience or textual analysis. To illustrate this perspective, we conclude by defining three ways to analyze video games in terms of “realism,” proposing three types of video game realism: representational, simulative, and inverse.
