Each event is divided into three regions based on the azimuthal angle with respect to the highest-pT jet direction: In the leading jet direction ("Toward"), opposite to the leading jet ("Away"), and perpendicular to the leading jet ("Transverse"). In the Transverse region, the average charged particle density is found to be between 0.4 and 0.6 and the mean transverse momentum

Abstract: The chiral magnetic effect (CME) is a novel transport phenomenon, arising from the interplay between quantum anomalies and strong magnetic fields in chiral systems. In high-energy nuclear collisions, the CME may survive the expansion of the quark-gluon plasma fireball and be detected in experiments. Over the past decade, the experimental searches for the CME have aroused extensive interest at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC). The main goal of this article is to investigate three pertinent experimental approaches: the $\gamma$ correlator, the $R$ correlator and the signed balance functions. We will exploit both simple Monte Carlo simulations and a realistic event generator (EBE-AVFD) to verify the equivalence in the kernel-component observables among these methods and to ascertain their sensitivities to the CME signal for the isobaric collisions at RHIC., Comment: 18 pages, 8 figures, 2 tables. Extended the discussion on R observable with the consideration of multiplicity fluctuation as used in practice

9. Evidence for Effects of the Chiral Anomaly: Status and Future

Author: Paul Sorensen
Subjects: Physics, Chiral anomaly, Nuclear and High Energy Physics, Identification (information), Strange matter, Theoretical physics, Particle physics, 010308 nuclear & particles physics, Interpretation (philosophy), 0103 physical sciences, Heavy ion, 010306 general physics, 01 natural sciences
Abstract: The unique identification of effects of the chiral anomaly in heavy ion collisions has been a challenge because alternative scenarios can often be constructed to explain the relevant findings. For this reason, the measurements remain open to interpretation. Because the unambiguous identification of effects caused by the chiral anomaly would represent one of the most profound discoveries from heavy ions, resolving these questions of interpretation is a priority for the field. Several new analyses were presented at Quark Matter 2017 and in this paper as in the summary talk, I attempt to present a clear picture of the most pressing questions and ideas on how to reach a clear conclusion.

Abstract: The Western Cape Province of South Africa has a Mediterranean climate of winter rainfall and hot, dry summers. The rivers have all been dammed to manage the available water resources. Every year at the end of summer, water restrictions are enforced by fines by the municipality in Cape Town, to ensure economies to eke out the dwindling reserves until the winter rains set in. The paper describes the situation in the 2017 dry season and examines possible solutions to the chronic water shortage such as use of ground water, desalination of sea water and recycling of waste water.

Abstract: We report new STAR measurements of the single-spin asymmetries $A_L$ for $W^+$ and $W^-$ bosons produced in polarized proton--proton collisions at $\sqrt{s}$ = 510 GeV as a function of the decay-positron and decay-electron pseudorapidity. The data were obtained in 2013 and correspond to an integrated luminosity of 250 pb$^{-1}$. The results are combined with previous results obtained with 86 pb$^{-1}$. A comparison with theoretical expectations based on polarized lepton-nucleon deep-inelastic scattering and prior polarized proton--proton data suggests a difference between the $\bar{u}$ and $\bar{d}$ quark helicity distributions for $0.05 < x < 0.25$. In addition, we report new results for the double-spin asymmetries $A_{LL}$ for $W^\pm$, as well as $A_L$ for $Z/\gamma^*$ production and subsequent decay into electron--positron pairs.

The yield of deuterons is found to be well described by the thermal model. The collision energy, centrality, and transverse momentum dependence of the coalescence parameter B2 are discussed. We find that the values of B2 for antideuterons are systematically lower than those for deuterons, indicating that the correlation volume of antibaryons is larger than that of baryons at sNN from 19.6 to 39 GeV. In addition, values of B2 are found to vary with collision energy and show a broad minimum around sNN=20-40 GeV, which might imply a change of the equation of state of the medium in these collisions.

Abstract: The beaching and disposal of the carcase of a 25t humpback whale was observed in the Strand, South Africa, just before Christmas in 2015. Despite the impending holiday, municipal services needed to dispose of the carcase timeously to prevent a risk to public health. As the beaching of whales in Cape Town occurs not infrequently, a protocol does exist.The carcase was dragged off the rocks and up the beach by bulldozers. After the road was closed, it was loaded on to a low bed trailer parked near the sea wall. As the trailer proved to be too small, it was reloaded on to a larger, replacement trailer. The carcase was then driven to the municipal landfill site at Vissershok for disposal.Background information is provided about the migratory habits of the Humpback whales that brought this specimen to Cape waters in the first place. Whale hunting in False Bay before the international moratorium in 1982 is also described.

Abstract: The concept of science has developed since it was equated to knowledge in ancient Rome. It acquired a narrower definition to include the systematic acquisition of knowledge. This has become the assimilation of quantitative data into theories describing the scientific topic in question. Because they share similar methods, the social sciences, the law etc. have been described as scientific in the modern era. These days, the ordering of qualitative data is also included under science. To examine the various connotations of science examples are drawn from physics, wine, the law, music, sport and information.

Abstract: The aim of this research was to understand the conditions under which time-varying tolls could be used to effectively smooth congestion on a downstream, untolled roadway. This question was answered in the context of the 183A Turnpike in Texas, but the analysis was extended to draw lessons for the potential use and evaluation of time-varying tolls as a congestion management strategy elsewhere. The study relied on two primary data sources: license plate reader data, to observe traffic routing, and a stated preference survey, to understand travelers’ trade-offs between travel time, tolls, and time-of-day shifts. A joint time-of-day and route choice model was developed and implemented in a spreadsheet for the rapid evaluation of a range of scenarios. Model inputs were then varied across key dimensions to achieve a better understanding of the conditions under which such a strategy might or might not be effective. The analysis revealed that under the conditions and constraints specific to the 183A corridor, time-of-day tolling would have a limited effect, but that there are a range of conditions for which time-of-day tolling could be a cost-effective means of managing downstream congestion.

Abstract: Global polarization of $\Lambda$ hyperons has been measured to be of the order of a few tenths of a percent in Au+Au collisions at $\sqrt{s_{_{NN}}}$ = 200 GeV, with no significant difference between $\Lambda$ and $\bar{\Lambda}$. These new results reveal the collision energy dependence of the global polarization together with the results previously observed at $\sqrt{s_{_{NN}}}$ = 7.7 -- 62.4 GeV and indicate noticeable vorticity of the medium created in non-central heavy-ion collisions at the highest RHIC collision energy. The signal is in rough quantitative agreement with the theoretical predictions from a hydrodynamic model and from the AMPT (A Multi-Phase Transport) model. The polarization is larger in more peripheral collisions, and depends weakly on the hyperon's transverse momentum and pseudorapidity $\eta^H$ within $|\eta^H

Development followed a core–periphery model that reflects its colonial past but this became a developmental state model under apartheid. There has however been an increase in inequality since the end of apartheid in 1994 as reflected in the Gini coefficient. Several development plans have been produced since 1994 ranging from Black Economic Empowerment to the most recent neoliberal, National Development Plan: Vision 2030 which emphasises the importance of mineral resources for economic development and job creation. Can mineral resources however give a second kick-start to development to address poverty and inequality under the modern, limit to growth, imposed by sustainable development?

Abstract: Technology advances in the field of small, unmanned aerial vehicles and their integration with a variety of sensor packages and instruments, such as miniature mass spectrometers, have enhanced the possibilities and applications of what are now called unmanned aerial systems (UAS). With such technology, in situ and proximal remote sensing measurements of volcanic plumes are now possible without risking the lives of scientists and personnel in charge of close monitoring of volcanic activity. These methods provide unprecedented, and otherwise unobtainable, data very close in space and time to eruptions, to better understand the role of gas volatiles in magma and subsequent eruption products. Small mass spectrometers, together with the world's smallest turbo molecular pump, have being integrated into NASA and University of Costa Rica UAS platforms to be field-tested for in situ volcanic plume analysis, and in support of the calibration and validation of satellite-based remote sensing data. These new UAS-MS systems are combined with existing UAS flight-tested payloads and assets, such as temperature, pressure, relative humidity, SO2, H2S, CO2, GPS sensors, on-board data storage, and telemetry. Such payloads are capable of generating real time 3D concentration maps of the Turrialba volcano active plume in Costa Rica, while remote sensing data are simultaneously collected from the ASTER and OMI space-borne instruments for comparison. The primary goal is to improve the understanding of the chemical and physical properties of emissions for mitigation of local volcanic hazards, for the validation of species detection and abundance of retrievals based on remote sensing, and to validate transport models.

Abstract: The STAR Collaboration reports the measurement of semi-inclusive distributions of charged-particle jets recoiling from a high transverse momentum hadron trigger, in central and peripheral $\mathrm{Au}+\mathrm{Au}$ collisions at $\sqrt{{s}_{\mathrm{NN}}}=200$ GeV. Charged jets are reconstructed with the anti-${k}_{\mathrm{T}}$ algorithm for jet radii $R$ between 0.2 and 0.5 and with low infrared cutoff of track constituents (${p}_{\mathrm{T}}g0.2 \mathrm{GeV}/\mathrm{c}$). A novel mixed-event technique is used to correct the large uncorrelated background present in heavy ion collisions. Corrected recoil jet distributions are reported at midrapidity, for charged-jet transverse momentum ${p}_{\mathrm{T},\mathrm{jet}}^{\mathrm{ch}}l30 \mathrm{GeV}/\mathrm{c}$. Comparison is made to similar measurements for $\mathrm{Pb}+\mathrm{Pb}$ collisions at $\sqrt{s}=2.76$ TeV, to calculations for $p+p$ collisions at $\sqrt{s}=200$ GeV based on the pythia Monte Carlo generator and on a next-to-leading order perturbative QCD approach, and to theoretical calculations incorporating jet quenching. The recoil jet yield is suppressed in central relative to peripheral collisions, with the magnitude of the suppression corresponding to medium-induced charged energy transport out of the jet cone of $2.8\ifmmode\pm\else\textpm\fi{}0.2(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}1.5(\mathrm{sys})$ $\mathrm{GeV}/c$, for $10l{p}_{\mathrm{T},\mathrm{jet}}^{\mathrm{ch}}l20$ $\mathrm{GeV}/c$ and $R=0.5$. No medium-induced change in jet shape is observed for $Rl0.5$. The azimuthal distribution of low-${p}_{\mathrm{T},\mathrm{jet}}^{\mathrm{ch}}$ recoil jets may be enhanced at large azimuthal angles to the trigger axis, due to scattering off quasiparticles in the hot QCD medium. Measurement of this distribution gives a 90% statistical confidence upper limit to the yield enhancement at large deflection angles in central $\mathrm{Au}+\mathrm{Au}$ collisions of $50\ifmmode\pm\else\textpm\fi{}30(\mathrm{sys})%$ of the large-angle yield in $p+p$ collisions predicted by pythia.

23. Toward a Culture of Consequences: Performance-Based Accountability Systems for Public Services

Author: Brian M, Stecher, Frank, Camm, Cheryl L, Damberg, Laura S, Hamilton, Kathleen J, Mullen, Christopher, Nelson, Paul, Sorensen, Martin, Wachs, Allison, Yoh, Gail L, Zellman, and Kristin J, Leuschner
Subjects: Health Care Delivery, Quality, and Patient Safety
Abstract: Performance-based accountability systems (PBASs), which link incentives to measured performance as a means of improving services to the public, have gained popularity. While PBASs can vary widely across sectors, they share three main components: goals, incentives, and measures. Research suggests that PBASs influence provider behaviors, but little is known about PBAS effectiveness at achieving performance goals or about government and agency experiences. This study examines nine PBASs that are drawn from five sectors: child care, education, health care, public health emergency preparedness, and transportation. In the right circumstances, a PBAS can be an effective strategy for improving service delivery. Optimum circumstances include having a widely shared goal, unambiguous observable measures, meaningful incentives for those with control over the relevant inputs and processes, few competing interests, and adequate resources to design, implement, and operate the PBAS. However, these conditions are rarely fully realized, so it is difficult to design and implement PBASs that are uniformly effective. PBASs represent a promising policy option for improving the quality of service-delivery activities in many contexts. The evidence supports continued experimentation with and adoption of this approach in appropriate circumstances. Even so, PBAS design and its prospects for success depend on the context in which it will operate. Also, ongoing system evaluation and monitoring are integral components of a PBAS; they inform refinements that improve system functioning over time. Empirical evidence of the effects of performance-based public management is scarce. This article also describes a framework used to evaluate a PBAS. Such a system identifies individuals or organizations that must change their behavior for the performance of an activity to improve, chooses an implicit or explicit incentive structure to motivate these organizations or individuals to change, and then chooses performance measures tailored to inform the incentive structure appropriately. The study focused on systems in the child care, education, health care, public health emergency preparedness, and transportation sectors, mainly in the United States. Analysts could use this framework to seek empirical information in other sectors and other parts of the world. Additional empirical information could help refine existing PBASs and, more broadly, improve decisions on where to initiate new PBASs, how to implement them, and then how to design, manage, and refine them over time.

Abstract: The Cape Town City Bowl is fed by a number of perennial springs that rise on the slopes of Table Mountain, thus given the name ‘Camissa’ the Place of Sweet Waters by the Khoi who inhabited the area before European settlement in 1652. Much of this water is piped to Table Bay where it is discharged, unused. Despite its Mediterranean climate of dry summers, there is not much fluctuation in flow rate from these springs. Condensation from the cloud cover on the mountain crest, caused by the prevailing S–E wind during the season is thought to be a significant agent for recharging the Table Mountain aquifers.

Abstract: The needs of future as well as those of the present generations are at the heart of sustainable development. Weak sustainability addresses specific concerns for the depletion of exhaustible resources such as minerals. So long as such natural capital is converted into reproducible machines, it is argued that the inevitable time when resources are depleted can be postponed, giving human ingenuity time to resolve the dilemma. But such machines require exhaustible energy to drive them and when they become obsolescent, other exhaustible resources such as iron ore to replace them. Further, with the underdeveloped parts of the world yet to experience the benefits of the industrialised, consumer society, there will be greater rather than lesser consumption of exhaustible resources in succeeding generations. The continuing need for exhaustible resources, therefore, argues against the arrival of a post-industrial society.

Abstract: Inflation and improved fuel economy have undermined revenue from federal and state excise taxes on gasoline and diesel; this situation has made it challenging to maintain and expand the nation's road network. With more stringent federal fuel economy standards and the emergence of alternative fuels threatening to accelerate this problem in future years, policymakers have begun to explore mileage-based user fees as a long-term replacement for fuel taxes. Unaffected by fuel type or fuel economy, mileage fees would provide more sustainable revenue, and the system could be structured to promote more efficient use of the roads, offer value-added motorist services, and collect travel data to support better network planning and operations. Mileage fees will likely cost more to administer than will fuel taxes, however, and the concept faces acceptance challenges related to privacy protection and other concerns. These obstacles in turn have spurred great innovation. On the basis of recent studies, trials, and implementation efforts, this paper presents a review of promising mileage-fee design and implementation strategies intended to reduce system costs and foster greater public acceptance.

Abstract: Since the discovery of diamonds in Kimberley in 1871 and the Witwatersrand goldfields in 1886, the mining industry has been a major contributor to the development of South Africa. The study examined Key Performance Indicators (KPIs) published by corporate mining companies (mining houses) in South Africa in their Annual Reports, to ascertain the extent to which the exploitation of the non-renewable resources under their control was done in a sustainable manner according to criteria set out in the Global Reporting Initiative (GRI). It was clear in terms of a graphical representation that while mining houses still strongly highlighted economic performance, and the traditional health and safety (labour) issues, as well as environment and social issues, the newcomers human rights and responsibility for downstream products were ignored. This points to an inconsistent understanding of the idea of sustainability espoused by the GRI.

Abstract: The paper examines the mining industry of South Africa from 1994 to the present, by reference to the legislative reforms and also the continuing contribution of mining to the economy of South Africa; with a focus on the case of gold. This is all affected by the push for ‘sustainable development’ (1987). In the past mining companies provided housing, clinics, schools, social amenities, and even infrastructure in mine towns, over and above the tax burden. In terms of the Mineral and Petroleum Development Act (2002) and related Mining Charter and Scorecard, it does not appear that the government expects any less in future. The influence of South Africa’s mineral endowment has diminished due mainly to expansion in the secondary and especially tertiary sectors of the economy. Social and environmental developments in mining are still emerging.

Abstract: The Mineral and Petroleum Development Act 28 of 2002 (MPRDA) that regulates the mining industry in South Africa requires undertakings to transfer 26% of ownership of existing mines to ‘Historically Disadvantaged South Africans’ (HDSAs) by 2014 before issuing ‘new‐order’ mining licences. It is clear that this target has yet to be met, although some may have benefitted. The MPRDA, its related Charter and Scorecard and the Mineral and Petroleum Resources Royalty Act 28 of 2008 are set in context. The government appears to have transferred the responsibility to provide the Constitution’s ‘right of access’ to housing, healthcare, food and water, to the mining industry who have to implement expensive labour and socio‐economic plans in addition to the loss of equity and the onerous tax burden.

Abstract: Recent data from heavy ion collisions at RHIC show strong near-side correlations extending over several units of rapidity. This ridge-like correlation exhibits an abrupt onset with collision centrality. In this talk, I argue that the centrality and beam-energy dependence of these near-angle correlations could provide access to information about the Quark Gluon Plasma phase boundary and the Equation of State of nuclear matter. A beam-energy-scan at RHIC will better reveal the true source of these correlations and should be a high priority at RHIC.

Abstract: The elliptic flow v2 and the fourth order anisotropic flow v4 of (Ω+Ω) have been studied in the framework a parton–hadronic transport model, namely a multi-phase transport (AMPT) model, for 197Au+197Au collisions at $\sqrt{s_{NN}}$ = 200 GeV and 62.4 GeV. The transverse momentum (pT) and the transverse kinetic energy (mT-m0) dependence of v2 and v4 are presented. The calculation in the AMPT model seems consistent with the STAR data. The results show that the v2 of (Ω+Ω) in 200 GeV obeys the constituent quark number scaling that has been observed for other mesons and baryons. Comparison of (Ω+Ω) elliptic flow v2 in the default version of AMPT, the melting version of AMPT and the RQMD model calculation, shows that the parton cascade process is important to reproduce the sizeable v2, and the string melting AMPT model preferably reproduces (Ω+Ω) elliptic flow v2 in 197Au+197Au collisions at $\sqrt{s_{NN}}$ = 200 GeV. The v2 of (Ω+Ω) in the 62.4 and 200 GeV collisions seem similar, and the pT dependence of (Ω+Ω) baryons’ v4 in 62.4 GeV and 200 GeV looks also similar in the string melting AMPT model, which indicates that a similar partonic matter phase has been reached in both energies.

Abstract: The equation of state of QCD matter for temperatures near and above the quark-hadron transition (165 MeV) is inferred within a Bayesian framework through the comparison of data from the Relativistic Heavy Ion Collider and from the Large Hadron Collider to theoretical models. State-of- the-art statistical techniques are applied to simultaneously analyze multiple classes of observables while varying 14 independent model parameters. The resulting posterior distribution over possible equations of state is consistent with results from lattice gauge theory., 4 pages, 5 figures

Abstract: This document provides a summary of the discussions during the recent joint QCD Town Meeting at Temple University of the status of and future plans for the research program of the relativistic heavy-ion community. A list of compelling questions is formulated, and a number of recommendations outlining the greatest research opportunities and detailing the research priorities of the heavy-ion community, voted on and unanimously approved at the Town Meeting, are presented. They are supported by a broad discussion of the underlying physics and its relation to other subfields. Areas of overlapping interests with the "QCD and Hadron Structure" ("cold QCD") subcommunity, in particular the recommendation for the future construction of an Electron-Ion Collider, are emphasized. The agenda of activities of the "hot QCD" subcommunity at the Town Meeting is attached., Comment: 34 pages of text, 254 references,16 figures

Abstract: This research examines the policy objectives, technical approaches, and political reactions associated with the current upsurge in electronic road pricing (ERP). The authors recently examined more than 90 implemented or proposed ERP projects around the globe, falling into four general categories: (a) facility congestion tolls, (b) cordon congestion tolls, (c) automated weight-distance truck tolls, and (d) distance-based user fees spanning entire road networks. Findings suggest that political and structural liabilities associated with traditional finance mechanisms—most notably motor fuel taxes—have motivated jurisdictions to explore alternatives such as local option sales taxes, public-private partnerships, and ERP. A compelling advantage of ERP is that it provides decision makers with what appears to be an effective tool for combating traffic congestion and automotive emissions. Meanwhile, many of the underlying technologies to support ERP have matured in recent years, enabling the rapid proliferation of experimentation and implementation in this arena.

Author: Paul Sorensen
Subjects: Economic efficiency, Sustainable development, Finance, Environmental justice, Government, business.industry, Mechanical Engineering, Sustainability, Economics, Revenue, Sales tax, business, Civil and Structural Engineering, Social equality
Abstract: With mounting concern about current social and environmental challenges, the notion of sustainable development—a paradigm calling for the integration of economic, social, and environmental goals—has gained increasing popularity in recent years. Within the transportation arena, sustainability advocates have argued for reducing reliance on the private automobile and seeking instead to foster alternative modes such as transit, biking, and walking; and many cities are actively pursuing this goal. Yet even the most concerted local efforts can be undermined by contradictory policy frameworks at higher levels of government, and a recent proposal for transportation finance reform in California serves as a good case in point. Intended to enhance the reliability of highway revenues, the proposal would eliminate a 5% sales tax on gasoline and replace it with a 0.25% increase in the general sales tax specifically earmarked for transportation. Basic economic analysis shows clearly, however, that eliminating the sales ...

Abstract: Measurements of identified particles from Au+Au collisions at $\sqrt{s_{_{NN}}}=200$ GeV are reviewed. Emphasis is placed on nuclear modification, baryon-to-meson ratios, and elliptic flow at intermediate transverse momentum ($1.5 < p_T < 5$ GeV/c). Possible connections between (1) these measurements, (2) the running coupling for static quark anti-quark pairs at finite temperature, and (3) the creation of a deconfined quark-gluon phase are presented. Modifications to hadronization in Au+Au collisions are proposed as a likely signature for the creation of deconfined colored matter., 8 pages, 5 figures, invited talk at the Strange Quark Matter 2004 conference, Cape Town, South Africa
