Nash Demand Game and the Kalai-Smorodinsky Solution

We introduce two new variations on the Nash demand game. One, like all known Nash-like demand games so far, has the Nash solution outcome as its equilibrium outcome. In the other, the range of solutions depends on an exogenous breakdown probability; surprisingly, the Kalai-Smorodinsky outcome proves to be the most robust equilibrium outcome. While the Kalai- Smorodinsky solution always finishes on top, there is no possible general ranking among the remaining solution concepts considered; in fact, the rest of the solution concepts take their turns at the bottom at various bargaining problems, depending on the specifics of the bargaining setup.

Game and training load differences in elite junior Australian football

Game demands and training practices within team sports such as Australian football (AF) have changed considerably over recent decades, including the requirement of coaching staff to effectively control, manipulate and monitor training and competition loads. The purpose of this investigation was to assess the differences in external and internal physical load measures between game and training in elite junior AF. Twenty five male, adolescent players (mean ±SD: age 17.6 ± 0.5 y) recruited from three elite under 18 AF clubs participated. Global positioning system (GPS), heart rate (HR) and rating of perceived exertion (RPE) data were obtained from 32 game files during four games, and 84 training files during 19 training sessions. Matched-pairs statistics along with Cohen's d effect size and percent difference were used to compare game and training events. Players were exposed to a higher physical load in the game environment, for both external (GPS) and internal (HR, Session-RPE) load parameters, compared to in-season training. Session time (d = 1.23; percent difference = 31.4% (95% confidence intervals = 17.4 - 45.4)), total distance (3.5; 63.5% (17.4 - 45.4)), distance per minute (1.93; 33.0% (25.8 - 40.1)), high speed distance (2.24; 77.3% (60.3 - 94.2)), number of sprints (0.94; 43.6% (18.9 - 68.6)), mean HR (1.83; 14.3% (10.5 - 18.1)), minutes spent above 80% of predicted HRmax (2.65; 103.7% (89.9 - 117.6)) and Session-RPE (1.22; 48.1% (22.1 - 74.1)) were all higher in competition compared to training. While training should not be expected to fully replicate competition, the observed differences suggest that monitoring of physical load in both environments is warranted to allow comparisons and evaluate whether training objectives are being met. Key pointsPhysical loads, including intensity, are typically lower in training compared to competition in junior elite Australian football.Monitoring of player loads in team sports should include both internal and external measures.Selected training drills should look to replicate game intensities, however training is unlikely to match the overall physical demands of competition.

A way through the dark and thorny thickets? The adjudication of ‘serious injury’ under the narrative tests in the Transport Accident Act 1986 (Vic) and the Workplace Injury Rehabilitation and Compensation Act 2013 (Vic)

The so-called narrative test provides the means by which injured persons who satisfy the statutory and common law definition of serious injury may bring proceedings for common law damages under s 93 of the Transport Accident Act 1986 (Vic) and s 134AB of the Accident Compensation Act 1985 (Vic) (or, for injuries after 1 July 2014, under ss 324-347 of the Workplace Injury Rehabilitation and Compensation Act 2013 (Vic)). These are among the most litigated provisions in Australia. This article outlines the legislative and political background to these provisions, the provisions themselves, and an account of the statutory and common law requirements needed to satisfy the provisions.

Guardian: game of editions

In 2013 The Guardian launched its third online iteration as 'Guardian Australia' - complementing "Guardian US' and Guardian UK'. Via these three digital editions the Guardian has expanded its global readership, which is one of its strategies to strengthen its future viability in the digital and mobile news sphere. The Guardian's journalists, while gathering news from around the world, now report in to the different news hubs. In the three main newsrooms, the journalists also create particular stories for their niche audiences in Australia, the USA and the UK. This paper examines the editorial content the Guardian has created on the back of digital disruption. Two months' worth of 'Editor's Picks' from across the three platforms are analysed to reveal how much the Guardian is promoting new, distinctive, locally created content versus how much it draws on material written by journalists from the other editions. This content is compared to data derived from interviewing those in charge of the three editions (Editor in chief Kath Viner, Guardian Australia Editor Emily Wilson and Guardian US Editor Lee Glendinning) plus interviews with other senior managers of the news organisation. In mid-2015 a fourth online edition of the Guardian began rolling out - Guardian International. This edition is not geo-specific and will instead promote and aggregate international news gathered from the other editions on its digital 'front page'. In January 2016 the Guardian announced it planned to cut annual costs by £53.6m due to rising losses: a move that will almost certainly involve staff redundancies. Later in the same month, Guardian Australia's editor, Emily Wilson, said in a public forum that the operations in Sydney and New York would be 'completely insulated' from these cuts. This paper explores the Guardian's global digital strategy during this difficult era for media that straddle the legacy and digital worlds.
