    The LHC at CERN is now undergoing a set of upgrades to increase the center of mass energy for the colliding particles to be able to explore new physical processes. The focus of this thesis lies on the so called phase II upgrade which will preliminarily be completed in 2023. After the upgrade the LHC will be able to accelerate proton beams to such a velocity thateach proton has a center of mass energy of 14 TeV. One disadvantage of the upgrade is that it will be harder for the atlas detector to isolate unique particle collisions since more and more collisions will occur simultaneously, so called pile-up. For 14 TeV there does not exist a full simulation of the atlas detector. This thesis instead uses data from Monte Carlo simulations for the particle collisions and then uses so called smearing functions to emulate the detector responses. This thesis focuses on how a mono-jet analysis looking for different wimp models of dark matter will be affected by this increase in pile-up rate. The signal models which are in focus are those which try to explain dark matter without adding new theories to the standard model or QFT, such as the effective theory D5 operator and light vector mediator models. The exclusion limits set for the D5 operators mass suppression scale at 14 TeV and 1000 fb-1are 2-3 times better than previous results at 8 TeV and 10 fb-1. For the first time limits have been set on which vector mediator mass models can be excluded at 14 TeV

    Risk, wealth and agrarian change in India: household-level hazards vs. late-modern global risks at different points along the risk transition

    The global poor often prioritise immediate hazards of food insecurity over temporally more distant risks like global warming. Yet the influence of socio-economic factors, temporal and spatial distance on risk perception remains under-researched. Data on risk perception and response were collected from two sets of Indian villages. Participatory approaches were used to investigate variations by socio-economic status, food security, age and gender. Villagers’ risk priorities reflected clear spatial and temporal patterns depending on land ownership, community group and education levels. Poorer groups prioritised household-level risks to health and food security while global environmental risks were mentioned by only three of the wealthiest respondents. The paper concludes that household risk perceptions and responses vary greatly with socio-economic status, age, gender and the spatial or temporal distance of the risk. These factors need to be better understood if the most significant contributors to the global burden of disease are to be reduced

    The Full Employment Mandate of the Federal Reserve: Its Origins and Importance

    Get PDF
    As we approach the 40th anniversary of the landmark Humphrey-Hawkins Act, this report underscores how the Federal Reserve's full employment mandate has made the Fed more accountable to working people. The report first traces the historical origins of the full employment mandate and highlights the pivotal but little-known role racial justice activists played in its creation. From the 1930s and through the rise of the civil rights movement, racial justice activists including Coretta Scott King, called for a coordinated federal effort to attain full employment. They envisioned an economy where every person who seeks employment can secure a job. King joined Congressional leaders Augustus Hawkins and Hubert Humphrey in eventually passing the landmark 1978 Full Employment and Balanced Growth Act (Humphrey-Hawkins) which legally required the Fed to pursue maximum employment.The report then turns to Federal Reserve monetary policy in the 1990's which offers an instructive model of what a full employment economy can look like. This real-world case study from our recent history shows that when labor markets tighten, workers begin to see broad-based wage gains, and persistent economic inequalities are reduced. Finally, the report underscores the continued importance of the full employment mandate today while providing an overview of proposed policies to eliminate or significantly curtail its effectiveness. In light of these findings, this report calls on Federal Reserve policymakers to use all tools at their disposal to fully realize the Fed's full employment mandate. Members of Congress must publicly affirm the importance of full employment while committing to reject any efforts to weaken or eliminate the full employment mandate. In particular, the Senate must reject nominees to the Board of Governors who have called for the narrowing of the Fed's mandate or who support policies that would undermine the Fed's ability to pursue full employment

    Matching methods to produce maps for pest risk analysis to resources

    Decision support systems (DSSs) for pest risk mapping are invaluable for guiding pest risk analysts seeking to add maps to pest risk analyses (PRAs). Maps can help identify the area of potential establishment, the area at highest risk and the endangered area for alien plant pests. However, the production of detailed pest risk maps may require considerable time and resources and it is important to match the methods employed to the priority, time and detail required. In this paper, we apply PRATIQUE DSSs to Phytophthora austrocedrae, a pathogen of the Cupressaceae, Thaumetopoea pityocampa, the pine processionary moth, Drosophila suzukii, spotted wing Drosophila, and Thaumatotibia leucotreta, the false codling moth. We demonstrate that complex pest risk maps are not always a high priority and suggest that simple methods may be used to determine the geographic variation in relative risks posed by invasive alien species within an area of concern

    Interface between pest risk science and policy : the EPPO perspective

    Get PDF
    The European and Mediterranean Plant Protection Organisation (EPPO) is an intergovernmental organization responsible for cooperation in plant protection in the European and Mediterranean region. It provides global distribution maps of pests, and intends to identify the areas at risk from new and emerging pests, in the framework of Pest Risk Analyses. EPPO has developed a decision-support scheme for Pest Risk Analysis (DSS) and a computer program (CAPRA) to assist pest risk analysts in running the decisionsupport scheme. Dedicated rating guidance and a Climatic Suitability Risk Mapping Decision-Support Scheme have recently been developed to guide assessors in identifying the potential area of establishment of a pest. All these tools have been developed taking into account both pest risk science available and needs of policy makers. The use of these tools and of mapping software are undertaken within the framework of EPPO Pest Risk Analyses, as illustrated through the examples of Thaumatotibia leucotreta (Lepidoptera) and Apriona germari (Coleoptera)

    Automating human skills : preliminary development of a human factors methodology to capture tacit cognitive skills

    Get PDF
    Despite technological advances in intelligent automation, it remains difficult for engineers to discern which manual tasks, or task components, would be most suitable for transfer to automated alternatives. This research aimed to develop an accurate methodology for the measurement of both observable and unobservable physical and cognitive activities used in manual tasks for the capture of tacit skill. Experienced operators were observed and interviewed in detail, following which, hierarchical task analysis and task decomposition methods were used to systematically explore and classify the qualitative data. Results showed that a task analysis / decomposition methodology identified different types of skill (e.g. procedural or declarative) and knowledge (explicit or tacit) indicating this methodology could be used for further human skill capture studies. The benefit of this research will be to provide a methodology to capture human skill so that complex manual tasks can be more efficiently transferred into automated processes

    Atypical Ductal Hyperplasia at the Margin of Lumpectomy Performed for Early Stage Breast Cancer: Is there Enough Evidence to Formulate Guidelines?

    Background. Negative margins are associated with a reduced risk of ipsilateral breast tumor recurrence (IBTR) in women with early stage breast cancer treated with breast conserving surgery (BCS). Not infrequently, atypical ductal hyperplasia (ADH) is reported as involving the margin of a BCS specimen, and there is no consensus among surgeons or pathologists on how to approach this diagnosis resulting in varied reexcision practices among breast surgeons. The purpose of this paper is to establish a reasonable approach to guide the treatment of ADH involving the margin after BCS for early stage breast cancer. Methods. the published literature was reviewed using the PubMed site from the US National Library of Medicine. Conclusions. ADH at the margin of a BCS specimen performed for early stage breast cancer is a controversial pathological diagnosis subject to large interobserver variability. There is not enough data evaluating this diagnosis to change current practice patterns; however, it is reasonable to consider reexcision for ADH involving a surgical margin, especially if it coexists with low grade DCIS. Further studies with longer followup and closer attention to ADH at the margin are needed to formulate treatment guidelines

    Character Strengths of Students At Risk of Dropping Out of High School

    The goal of this study was to determine the participants\u27 perceptions about what strengths at-risk students who follow through and graduate from high school have, using the conceptual framework of positive psychology, and its classification system of virtues and character strengths. To reveal the strengths of these students, this study used a qualitative methodology, interpretive phenomenological analysis (IPA). In addition, the participants were asked to fill out a Likert scale survey to rate how frequently at-risk students who graduated employed each of the 24 VIA characteristics. The purpose of this study was to add to the under-researched area of identifying the strengths and not the weaknesses of those students at risk of dropping out but made it to graduation. This study should also raise awareness in the field of positive psychology, suggesting that the strengths of this population differ from the general adolescent population
