    Voices for Change: A Taxonomy of Public Communications Campaigns and Their Evaluation Challenges

    Get PDF
    Makes the case that communications campaigns cover a broad range of different types and characteristics, and can be differentiated along the axes of purpose, scope, and maturity. Examines what communications campaigns that fall on different areas of these three axes look like, and how where they fall may affect the evaluation approach used and lead to distinct evaluation challenges and needs

    Performance of the CMS Cathode Strip Chambers with Cosmic Rays

    Get PDF
    The Cathode Strip Chambers (CSCs) constitute the primary muon tracking device in the CMS endcaps. Their performance has been evaluated using data taken during a cosmic ray run in fall 2008. Measured noise levels are low, with the number of noisy channels well below 1%. Coordinate resolution was measured for all types of chambers, and fall in the range 47 microns to 243 microns. The efficiencies for local charged track triggers, for hit and for segments reconstruction were measured, and are above 99%. The timing resolution per layer is approximately 5 ns

    Imaginaries and definable types in algebraically closed valued fields

    Full text link
    The text is based on notes from a class entitled {\em Model Theory of Berkovich Spaces}, given at the Hebrew University in the fall term of 2009, and retains the flavor of class notes. It includes an exposition of material from \cite{hhmcrelle}, \cite{hhm} and \cite{HL}, regarding definable types in the model completion of the theory of valued fields, and the classification of imaginary sorts. The latter is given a new proof, based on definable types rather than invariant types, and on the notion of {\em generic reparametrization}. I also try to bring out the relation to the geometry of \cite{HL} - stably dominated definable types as the model theoretic incarnation of a Berkovich point

    Are speed enforcement cameras more effective than other speed management measures? The impact of speed management schemes on 30mph roads.

    This paper presents the results of an evaluation of the impact of various types of speed management schemes on both traffic speeds and accidents. The study controls for general trends in accidents, regression-to-mean effects and migration, separately estimating the accident changes attributable to the impact of the schemes on traffic speed and on traffic volume. It was found that, when judged in absolute terms, all types of speed management scheme have remarkably similar effects on accidents, with an average fall in personal injury accidents of about 1 accident/km/year. In terms of the percentage accident reduction, however, engineering schemes incorporating vertical deflections (such as speed humps or cushions) offer the largest benefits: at 44%, the average reduction in personal injury accidents attributable to such schemes, is twice that at sites where safety cameras were used to control speeds (22%) and they were the only type of scheme to have a significant impact on fatal and serious accidents. Other types of engineering scheme (with a fall of 29% in personal injury accidents) were on average less effective in reducing accidents than schemes with vertical features but more effective than cameras. All types of scheme were generally effective in reducing speeds, with the largest reductions tending to be obtained with vertical deflections and the smallest with other types of engineering schemes

    Transport and Combustion of Firebrands. Final Report of Grants FG-SP-114 and FG-SP-146 Vol. II

    A theoretical and experimental study has been carried out on the combustion properties and flight paths of firebrands when they are carried upwards by convective currents and then forwards by the winds. The study has shown that the flight paths of firebrands can be fall decreases continuously as the firebrand burns. Several types of wind tunnels have been developed especially designed to study combustion of firebrands at their final velocity of fall. The study has also show that combustion of firebrands at constant wind speed. The influence of the initial size and initial shape of the firebrands, kind of wood and initial moisture content has been studied, as well as the influence of several types convection columns configurations. Results of these studies enable the calculation of the maximum range of possible fire spread by firebrands of given initial characteristics, once the convective currents above the fire are known as vell as the horizontal wind conditions

    Spiritual Values and Evaluations

    Get PDF
    This book explores three easily recognized personality types of great spiritual significance--worldliness, ideology, and saintliness. These spiritual types are defined by the dominant values they manifest--extrinsic, systemic, or intrinsic. The thoughts, experiences, actions, feelings, and overall characters and behaviors of people belonging to these types are shaped and expressed by what and how they value, as the chapters in the book explain. A distinctive mode of spirituality is correlated with each type, based on what and how religious people most value. What and how people value are the keys to everyone's personalities, whether spiritual or not. Real people do not fall neatly or completely into any one of these types, but in most people some dimension of value is dominant over the others, and this has great spiritual, moral, and practical significance

    The impact of worker values on client outcomes within a drug treatment service

    Get PDF
    Background: Little attention has been paid to understanding the impact of values, attributes and characteristics of drugs workers on therapeutic relationships and treatment outcomes. Interaction of values with other variables is considered to be of importance since values play a role in determining attitudes and behaviours. This exploratory study investigates the impact of drug workers’ personal values on client outcomes within a drug treatment service. Methods: 8 drug workers and 58 clients were recruited at a UK charity working with problematic drug users who are also socially excluded. Drug workers completed a validated questionnaire (Schwartz, 1992) to elicit their personal values. Client outcomes were assessed using the Christo Inventory for Substance Misuse Services (Christo et al., 2000). The relationship between client outcomes and worker values were analysed using Spearman’s rank test of association. Results: Drug workers prioritising stimulation, self-direction and hedonism value types experienced more positive client outcomes compared with those prioritising security, conformity, benevolence, tradition and universalism types. The value types associated with positive outcomes fall within Schwartz’s ‘openness to change’ superordinate dimension, whereas those related to more negative outcomes fall within the ‘conservation’ dimension. Conclusion: The study suggests that drug workers’ personal values may have a significant impact upon client outcomes in the treatment of substance misuse. Reasons for this finding are explored, as are limitations of this study and suggestions for future research
