    Get PDF
    Tourism is one of the largest global economic sectors, is a vital contributor to the economy of many nations, and is highly promoted as an important means of future development and poverty reduction in developing countries. The interface between climate and tourism is multifaceted and complex, with broad significance for tourist decision-making and expenditures, as well as industry marketing and operations worldwide. With the close relationship of tourism to the environment and climate, the integrated effects of climate change are anticipated to markedly affect tourism businesses and destinations, as well as the destination choices and mobility of individual tourists in the decades ahead. As recent major natural, political, and economic shocks have demonstrated, the tourism sector has relatively high adaptive capacity. Improved climate services will be vital for travelers and tourism businesses and destinations to adapt to climate change in an economically, socially, and environmentally sustainable manner. This paper outlines the range of applications of weather and climate information within the tourism sector and discusses priorities for future work to advance climate services for weather risk management and climate change adaptation for the tourism sector

    Medical student experiences in clinical reproductive medicine: dual-cohort assessment of a new learning module at the Royal College of Surgeons in Ireland

    Aims: Exposure to a structured curriculum in reproductive medicine during medical school is helpful given the high frequency of fertility and pregnancy-related issues that future physicians will encounter. This study sought to evaluate a new reproductive medicine module for medical students. Study Design: Prospective cohort study. Place and Duration of Study: Dublin, Ireland; 2008-2010. Methodology: A new educational module in reproductive medicine for upper-level medical students was initiated in 2008 at the Royal College of Surgeons in Ireland (RCSI). The module included reproductive endocrinology lectures, laboratory sessions, and direct observation of clinical consultations as a required component of an obstetrics and gynaecology rotation. Students were assigned to this module on the basis of random allocation by departmental administration. The current investigation used an anonymous questionnaire and a MCQ exam to measure academic performance and student acceptance of this module, at launch and again two years later. The first sampling was from the pilot class in 2008 and a second group was evaluated in 2010. No student was in both groups. Results: 42 of 66 students completed the evaluation in 2008, and 71 of 98 did so in 2010. Mean±SD medical student age and average examination scores were comparable for the two groups. In both samples, most students (95.5%) had no prior lectures on reproductive endocrinology, and most indicated improvement in their level of understanding after the module. Both laboratory and clinical features were scored highly by students. Conclusion: At present, there is no standardised medical student curriculum for reproductive medicine in Ireland. This report is the first to describe a structured learning experience in this subspecialty area for medical students in Ireland. Additional studies are planned to track knowledge acquisition and career impact specific to reproductive medicine based on this module

    Mobilising knowledge in complex health systems: a call to action

    Get PDF
    Worldwide, policymakers, health system managers, practitioners and researchers struggle to use evidence to improve policy and practice. There is growing recognition that this challenge relates to the complex systems in which we work. The corresponding increase in complexity-related discourse remains primarily at a theoretical level. This paper moves the discussion to a practical level, proposing actions that can be taken to implement evidence successfully in complex systems. Key to success is working with, rather than trying to simplify or control, complexity. The integrated actions relate to co-producing knowledge, establishing shared goals and measures, enabling leadership, ensuring adequate resourcing, contributing to the science of knowledge-to-action, and communicating strategically

    Muon reconstruction performance of the ATLAS detector in proton–proton collision data at √s = 13 TeV

    Get PDF
    This article documents the performance of the ATLAS muon identification and reconstruction using the LHC dataset recorded at √s = 13 TeV in 2015. Using a large sample of J/ψ→ΌΌ and Z→ΌΌ decays from 3.2 fb−1 of pp collision data, measurements of the reconstruction efficiency, as well as of the momentum scale and resolution, are presented and compared to Monte Carlo simulations. The reconstruction efficiency is measured to be close to 99% over most of the covered phase space (|η| 2.2, the pT resolution for muons from Z→ΌΌ decays is 2.9 % while the precision of the momentum scale for low-pT muons from J/ψ→ΌΌ decays is about 0.2%

    Measurement of the dependence of transverse energy production at large pseudorapidity on the hard-scattering kinematics of proton-proton collisions at √s=2.76 TeV with ATLAS

    Get PDF
    The relationship between jet production in the central region and the underlying-event activity in a pseudorapidity-separated region is studied in 4.0 pb-1 of s=2.76 TeV pp collision data recorded with the ATLAS detector at the LHC. The underlying event is characterised through measurements of the average value of the sum of the transverse energy at large pseudorapidity downstream of one of the protons, which are reported here as a function of hard-scattering kinematic variables. The hard scattering is characterised by the average transverse momentum and pseudorapidity of the two highest transverse momentum jets in the event. The dijet kinematics are used to estimate, on an event-by-event basis, the scaled longitudinal momenta of the hard-scattered partons in the target and projectile beam-protons moving toward and away from the region measuring transverse energy, respectively. Transverse energy production at large pseudorapidity is observed to decrease with a linear dependence on the longitudinal momentum fraction in the target proton and to depend only weakly on that in the projectile proton. The results are compared to the predictions of various Monte Carlo event generators, which qualitatively reproduce the trends observed in data but generally underpredict the overall level of transverse energy at forward pseudorapidity

    Search for strong gravity in multijet final states produced in pp collisions at √s=13 TeV using the ATLAS detector at the LHC

    Get PDF
    A search is conducted for new physics in multijet final states using 3.6 inverse femtobarns of data from proton-proton collisions at √s = 13TeV taken at the CERN Large Hadron Collider with the ATLAS detector. Events are selected containing at least three jets with scalar sum of jet transverse momenta (HT) greater than 1TeV. No excess is seen at large HT and limits are presented on new physics: models which produce final states containing at least three jets and having cross sections larger than 1.6 fb with HT > 5.8 TeV are excluded. Limits are also given in terms of new physics models of strong gravity that hypothesize additional space-time dimensions

    Search for massive, long-lived particles using multitrack displaced vertices or displaced lepton pairs in pp collisions at √s = 8 TeV with the ATLAS detector

    Get PDF
    Many extensions of the Standard Model posit the existence of heavy particles with long lifetimes. This article presents the results of a search for events containing at least one long-lived particle that decays at a significant distance from its production point into two leptons or into five or more charged particles. This analysis uses a data sample of proton-proton collisions at √s=8  TeV corresponding to an integrated luminosity of 20.3  fb−1 collected in 2012 by the ATLAS detector operating at the Large Hadron Collider. No events are observed in any of the signal regions, and limits are set on model parameters within supersymmetric scenarios involving R-parity violation, split supersymmetry, and gauge mediation. In some of the search channels, the trigger and search strategy are based only on the decay products of individual long-lived particles, irrespective of the rest of the event. In these cases, the provided limits can easily be reinterpreted in different scenarios

    Measurement of the cross section for isolated-photon plus jet production in pp collisions at √s=13 TeV using the ATLAS detector

    Get PDF
    The dynamics of isolated-photon production in association with a jet in proton–proton collisions at a centre-of-mass energy of 13 TeV are studied with the ATLAS detector at the LHC using a dataset with an integrated luminosity of 3.2 fb−1. Photons are required to have transverse energies above 125 GeV. Jets are identified using the anti- algorithm with radius parameter and required to have transverse momenta above 100 GeV. Measurements of isolated-photon plus jet cross sections are presented as functions of the leading-photon transverse energy, the leading-jet transverse momentum, the azimuthal angular separation between the photon and the jet, the photon–jet invariant mass and the scattering angle in the photon–jet centre-of-mass system. Tree-level plus parton-shower predictions from Sherpa and Pythia as well as next-to-leading-order QCD predictions from Jetphox and Sherpa are compared to the measurements
