Guitar hero world tour: a creator of new sonic experiences?

The academic literature for sonic media and gaming is – too frequently – separated by method, politics and approach. To increase the dialogue between gaming and sonic discourses, this paper discusses the impact of the drum controller (for use with the Guitar Hero gaming software) and the potential for new auditory experiences and literacies. Sonic media is often more volatile than screen-based platforms. The advent of MP3s and the iPod has ensured that sound is the carrier for changes in media and meaning. There has been an evolution of technology which has subsequently configured a convergence or revolution in sonic media. Concurrently, there has been a growing trend in the gaming industry to replicate instruments into alternative controllers for rhythm games as a form of interactive entertainment. Generally, these input devices are considered as part of rhythm play rather that music generation. Predominant in this group of devices is the Guitar Hero© franchise where a controller is shaped like a guitar. While it does not feature strings, it has buttons that are pressed as part of the use of such controllers. In 2008, drums were added to this equation for the current seventh generation of consoles (PS3, XBOX 360, and Wii) with the release of a drum controller for the games Guitar Hero World Tour (GHWT), Rock Band (RB) and Rock Revolutions (it is worth noting that PS2 a sixth generation console is also supported to some extent).

What is the role of informal healthcare providers in developing countries? A systematic review.

Informal health care providers (IPs) comprise a significant component of health systems in developing nations. Yet little is known about the most basic characteristics of performance, cost, quality, utilization, and size of this sector. To address this gap we conducted a comprehensive literature review on the informal health care sector in developing countries. We searched for studies published since 2000 through electronic databases PubMed, Google Scholar, and relevant grey literature from The New York Academy of Medicine, The World Bank, The Center for Global Development, USAID, SHOPS (formerly PSP-One), The World Health Organization, DFID, Human Resources for Health Global Resource Center. In total, 334 articles were retrieved, and 122 met inclusion criteria and chosen for data abstraction. Results indicate that IPs make up a significant portion of the healthcare sector globally, with almost half of studies (48%) from Sub-Saharan Africa. Utilization estimates from 24 studies in the literature of IP for healthcare services ranged from 9% to 90% of all healthcare interactions, depending on the country, the disease in question, and methods of measurement. IPs operate in a variety of health areas, although baseline information on quality is notably incomplete and poor quality of care is generally assumed. There was a wide variation in how quality of care is measured. The review found that IPs reported inadequate drug provision, poor adherence to clinical national guidelines, and that there were gaps in knowledge and provider practice; however, studies also found that the formal sector also reported poor provider practices. Reasons for using IPs included convenience, affordability, and social and cultural effects. Recommendations from the literature amount to a call for more engagement with the IP sector. IPs are a large component of nearly all developing country health systems. Research and policies of engagement are needed

Crafting Courts in New Democracies: The Politics of Subnational Judicial Reform in Brazil and Mexico

Why does the strength of local courts vary in new democracies? Highlighting empirical and theoretical puzzles generated by the state-level variation in court strength within Latin Americas two largest democracies, Brazil and Mexico, this study offers a historical institutional explanation of judicial change. Notably, in contrast to much \u27new institutionalist\u27 work — which examines the effects of formal instititutional arrangements — judicial institutions here are the dependent variable. The theoretical framework builds on existing explanations regarding the effects of electoral competition and ideology, specifying underlying causal logics and mechanisms. The framework also highlights the role of actors internal to institutions (judges), and the importance of social movement theory for understanding interactions between ideological judges and sympathetic actors outside the institution, leading to judicial mobilization or behavior \u27beyond the bench. The empirical analysis draws on the analytic leverage of a subnational level of analysis and integrates quantitative and qualitative methods, yielding conclusions that would be impossible using either method in isolation. First, time-series cross-section analyses of judicial spending (as a proxy for court strength) examine broad relationships across Brazil\u27s 26 states from 1985 to 2006 and Mexico\u27s 31 states from 1993-2007. Quantitative tools for case selection identify \u27nested\u27, model-testing cases, around which I build small-N research designs consisting of three states in each country. The in-depth, qualitative analysis draws on 115 personal, semi-structured interviews with judges and other legal elites, archival evidence, and direct observation to trace the process of judicial change. Overall, electoral competition operates as a pre-condition for reform, but its effect is indeterminate once a minimum threshold of competition is crossed. Ideology has the most consistent and meaningful effect on reform. Actors and their intentions matter. However, the expression of these intentions is contingent upon the nature of opportunity structures, including mobilization strategies and alliances, as well as overlapping historical processes. In short, I find that strong reforms are most likely where progressive judges coincide with sympathetic, left-of-center politicians. The results emphasize the role of ideas and the conditional expression of these ideas, that is, the contingency of intentionality

Hidden in Plain Sight: Homeless Students In America's Public Schools

Student homelessness is on the rise, with more than 1.3 million homeless students identified during the 2013-14 school year. This is a 7 percent increase from the previous year and more than double the number of homeless students in 2006-07. As high as these numbers seem, they are almost certainly undercounts.Despite increasing numbers, these students - as well as the school liaisons and state coordinators who support them - report that student homelessness remains an invisible and extremely disruptive problem.Students experiencing homelessness struggle to stay in school, to perform well, and to form meaningful connections with peers and adults. Ultimately, they are much more likely to fall off track and eventually drop out of school more often than their non-homeless peers.This study:provides an overview of existing research on homeless students,sheds light on the challenges homeless students face and the supports they say they need to succeed,reports on the challenges adults - local liaisons and state coordinators - face in trying to help homeless students, andrecommends changes in policy and practice at the school, community, state and national level to help homeless students get on a path to adult success.This is a critical and timely topic. The recent reauthorization of the Every Student Succeeds Act (ESSA) provides many new and stronger provisions for homeless students (effective Oct. 1, 2016); requires states, district and schools for the first time to report graduation rates for homeless students (effective beginning with the 2016-17 school year); and affirms the urgency and importance of dealing with homelessness so that all children can succeed

Testing Modeling Assumptions in the West Africa Ebola Outbreak

The Ebola virus in West Africa has infected almost 30,000 and killed over 11,000 people. Recent models of Ebola Virus Disease (EVD) have often made assumptions about how the disease spreads, such as uniform transmissibility and homogeneous mixing within a population. In this paper, we test whether these assumptions are necessarily correct, and offer simple solutions that may improve disease model accuracy. First, we use data and models of West African migration to show that EVD does not homogeneously mix, but spreads in a predictable manner. Next, we estimate the initial growth rate of EVD within country administrative divisions and find that it significantly decreases with population density. Finally, we test whether EVD strains have uniform transmissibility through a novel statistical test, and find that certain strains appear more often than expected by chance.Comment: 16 pages, 14 figure

Formation of Precessing Jets by Tilted Black-hole Discs in 3D General Relativistic MHD Simulations

Gas falling into a black hole (BH) from large distances is unaware of BH spin direction, and misalignment between the accretion disc and BH spin is expected to be common. However, the physics of tilted discs (e.g., angular momentum transport and jet formation) is poorly understood. Using our new GPU-accelerated code H-AMR, we performed 3D general relativistic magnetohydrodynamic simulations of tilted thick accretion discs around rapidly spinning BHs, at the highest resolution to date. We explored the limit where disc thermal pressure dominates magnetic pressure, and showed for the first time that, for different magnetic field strengths on the BH, these flows launch magnetized relativistic jets propagating along the rotation axis of the tilted disc (rather than of the BH). If strong large-scale magnetic flux reaches the BH, it bends the inner few gravitational radii of the disc and jets into partial alignment with the BH spin. On longer time scales, the simulated disc-jet system as a whole undergoes Lense-Thirring precession and approaches alignment, demonstrating for the first time that jets can be used as probes of disc precession. When the disc turbulence is well-resolved, our isolated discs spread out, causing both the alignment and precession to slow down.Comment: MNRAS Letters, accepted.

Timing properties of ULX pulsars: optically thick envelopes and outflows

It has recently been discovered that a fraction of ultra-luminous X-ray sources (ULXs) exhibit X-ray pulsations, and are therefore powered by super-Eddington accretion onto magnetized neutron stars (NSs). For typical ULX mass accretion rates ($\gtrsim 10^{19}\,{\rm g\,s^{-1}}$), the inner parts of the accretion disc are expected to be in the supercritical regime, meaning that some material is lost in a wind launched from the disc surface, while the rest forms an optically thick envelope around the NS as it follows magnetic field lines from the inner disc radius to the magnetic poles of the star. The envelope hides the central object from a distant observer and defines key observational properties of ULX pulsars: their energy spectrum, polarization, and timing features. The optical thickness of the envelope is affected by the mass losses from the disc. We calculate the mass loss rate due to the wind in ULX pulsars, accounting for the NS magnetic field strength and advection processes in the disc. We argue that the detection of strong outflows from ULX pulsars can be considered evidence of a relatively weak dipole component of the NS magnetic field. We estimate the influence of mass losses on the optical thickness of the envelope and analyze how the envelope affects broadband aperiodic variability in ULXs. We show that brightness fluctuations at high Fourier frequencies can be strongly suppressed by multiple scatterings in the envelope and that the strength of suppression is determined by the mass accretion rate and geometrical size of the magnetosphere.Comment: 12 pages, 11 figures, accepted for publication in MNRA

PREVENTING TACKLE INJURY EVENTS IN RUGBY UNION

This paper reports a programme of studies; describing the nature and circumstances of tackle injuries in rugby union, the type of tackle and player actions which were risk factors for the tackle injury, and proposed modification of player actions leading up to the tackle to reduce the risk of tackle injury. The stopping tackle was the most prevalent and the most common tackle associated with injury was the high stopping tackle from the front or side. Tackle types and player actions that pose particular risks of injury are dentified as well as possible areas in which coaching, refereeing or law changes may help to reduce the risk of rugby tackle injury
