Decent work over the course of a life
No full textLife revolves around work for the vast majority of the adult population worldwide. The centrality of work in people’s lives makes it a key aspect of the United Nations (UN) Sustainable Development Goals (SDGs). This chapter problematises the notion of sustainable development in the context of working life by focusing on SDG 8 and Target 8.5, ‘Full employment and decent work with equal pay’. Based on the target indicators of Target 8.5, we evaluated the prerequisites for sustainability considering prolonged working life policies using senior workers as an example. We identified current challenges in materialising the targets in Target 8.5 in the Global North and South while acknowledging the role of occupation, sex, and personal disabilities. Specifically, we present examples of (a) discrepancies between the vision in Target 8.5 and the realities of contemporary working life; (b) the advantages and limitations of the selected indicators in Target 8.5; and (c) alternative and more comprehensive SDG indicators. Moreover, we (d) demonstrate how research on working life can help detect hazardous working environments, unequal employment relationships, and hidden discrimination in the labour market. Finally, we (e) describe societal, organisational, and individual conditions that hinder or promote full, equal, and sustainable employment
Epidemiology of Stroke Long-term Trends in Stroke Incidence in New Zealand: 1981-2012
No full textBackground: In the context of declining stroke mortality rates, reliable data on long-term trends of stroke incidence and case fatality is required to understand reasons for the decline and to plan long-term health care stroke services and to monitor the effects of stroke prevention in the community
Production of charged pions, kaons and protons at large transverse momenta in pp and Pb–Pb collisions at TeV
No full textTransverse momentum spectra of pi(+/-), K-+/- and p((p) over bar) up to p(T) = 20 GeV/c at mid-rapidity in pp, peripheral (60-80%) and central (0-5%) Pb-Pb collisions at v root s(NN) = 2.76 TeV have been measured using the ALICE detector at the Large Hadron Collider. The proton-to-pion and the kaon-to-pionratios both show a distinct peak at p(T) approximate to 3 GeV/c in central Pb-Pb collisions. Below the peak, p(T) 10 GeV/c particle ratios in pp and Pb-Pb collisions are in agreement and the nuclear modification factors for pi(+/-), K-+/- and p((p) over bar) indicate that, within the systematic and statistical uncertainties, the suppression is the same. This suggests that the chemical composition of leading particles from jets in the medium is similar to that of vacuum jets
Reasonable Non-conventional Generator of Random Linear Chains Based on a Simple Self-avoiding Walking Process: A Statistical and Fractal Analysis
No full textModels based on self-excluded walks have been widely used to generate random linear chains. In this work, we present an algorithm capable of generating linear strings in two and three dimensions, in a simple and efficient way. The discrete growth process of the chains takes place in a finite time, in a network without pre-established boundary conditions and without the need to explore the entire configurational space. The computational processing time and the length of the strings depending on the number of trials N′ . This number is always less than the real number of steps in the chain, N. From the statistical analysis of the characteristic distances, the radius of gyration ( Rg ), and the end-to-end distance ( Ree ), we make a morphological description of the chains and we study the dependence of this quantities on the number of steps, N. The universal critical exponent obtained are in very good agreement with previous values reported in literature. We also study fractal characteristics of the chains using two different methods, Box-Counting Dimension or Capacity Dimension and Correlation Dimension. The studies revealed essential differences between chains of different dimensions, for the two methods used, showing that three-dimensional chains are more correlated than two-dimensional chains.Avellaneda B., David R.R.

Measurement of visible cross sections in proton-lead collisions at = 5.02 TeV in van der Meer scans with the ALICE detector
No full textIn 2013, the Large Hadron Collider provided proton-lead and lead-proton collisions at the center-of-mass energy per nucleon pair root s(NN) = 5.02 TeV. Van der Meer scans were performed for both configurations of colliding beams, and the cross section was measured for two reference processes, based on particle detection by the T0 and V0 detectors, with pseudo-rapidity coverage 4.6 < eta < 4.9, -3.3 < eta < -3.0 and 2.8 < eta < 5.1, -3.7 < eta < -1.7, respectively. Given the asymmetric detector acceptance, the cross section was measured separately for the two configurations. The measured visible cross sections are used to calculate the integrated luminosity of the proton-lead and lead-proton data samples, and to indirectly measure the cross section for a third, configuration-independent, reference process, based on neutron detection by the Zero Degree Calorimeters
Performance of the ALICE experiment at the CERN LHC
No full textALICE is the heavy-ion experiment at the CERN Large Hadron Collider. The experiment continuously took data during the first physics campaign of the machine from fall 2009 until early 2013, using proton and lead-ion beams. In this paper we describe the running environment and the data handling procedures, and discuss the performance of the ALICE detectors and analysis methods for various physics observables
Technical Design Report for the Upgrade of the ALICE Inner Tracking System
No full textALICE (A Large Ion Collider Experiment) is preparing a major upgrade of its experimental apparatus, planned for installation in the second long LHC shutdown (LS2) in the years 2018-2019. These plans are presented in the ALICE Upgrade Letter of Intent submitted to the LHCC in September 2012. A key element of the upgrade is the construction of a new, ultra-light, high-resolution Inner Tracking System based on monolithic pixel detectors. This Technical Design Report is an update of the Conceptual Design Report for the Upgrade of the ALICE Inner Tracking System, which was presented to the LHCC in September 2012. The primary focus of the ITS upgrade is on the improved performance for detection of heavy-flavour hadrons, and of thermal photons and low-mass di-electrons emitted by the QGP. The Conceptual Design Report demonstrated that it is possible to build a new silicon tracker with greatly improved features in terms of determination of the distance of closest approach to the primary vertex, tracking efficiency at low transverse momenta, and read-out rate capabilities. This document presents an update of R&D activities, with particular focus on the technical implementation of the main detector components, and detector and physics performance. The detector performance and physics studies are based on Monte Carlo simulations that include the transport of particles in a detailed model of the new detector
