Where's the best medicine? The hospital rating game

On July 18, 1994, U.S. News and World Report published its annual ranking of America's best hospitals. The rankings were based on a model developed by the National Opinion Research Center (NORC). National rankings are a type of program evaluation that deserve careful scrutiny with regard to their methods. While problems with measurement validity are discussed, the principle concern here was the model used to compile a final ranking of hospitals. The News-NORC model is typical of ranking schemes that usually reduce higher levels of measurement to lower ones in order to compute final scores. Such simple tabulation techniques, however, distort the ratios between the scores and bias the results. A type of percentaging, using part/whole percentages (P/W%), was used to show the differences between hospital rankings when data are kept at higher levels of measurement, such as interval or ratio levels. Percentaging methods produce more valid results when comparatively evaluating programs whether the goal is to produce national rankings or some other outcome.     

Defectors’ niches: prisoner's dilemma game on disordered networks

Effects of disordered networks on evolution of cooperation are studied based on the prisoner's dilemma game on a random regular relational graph. As a parameter q (0 ≤ q ≤ 1) that controls a degree of randomness of the network varies from zero to unity, the initial two-dimensional square lattice network becomes more relationally randomized while regularity of the network is kept. It is shown that random connections that make possible cooperator jump into defectors’ clusters ironically trigger the formation of defectors’ niches, in which defectors impose upon cooperators and do not have incentive to change their strategy.     

The beautiful game and the proto‐aesthetics of the everyday

Abstract

This article provides a critique of the postmodernist notion that there has been of recent years a dissolution of the divide between aesthetics and practical activities, between Art and Life. It does so by considering the game of soccer from a phenomenological viewpoint, which shows that the game possesses intrinsically ‘aesthetic’ qualities. The conditions of possibility of such qualities are understood by introducing the idea of the ‘proto‐aesthetics’ of soccer and other mundane phenomena. By considering the proto‐aesthetics of the quotidian we argue that recent changes in the nature of practical life should not be regarded as due to ‘aestheticisation’ but rather as springing from processes of commodification.     

Video game playing,dependency and delinquency: A question of methodology?

A methodological challenge to Fisher's (1992) study of adolescent fruit machine gamblers was carried out with young video game players. Fisher (1992) described an association between frequency fruit machine playing, dependency and delinquency. Some methodological concerns were considered that might weaken this conclusion, in particular the use of heterogeneous measures that fail to distinguish between variables. As such measures feature elsewhere in contemporary gambling research it was deemed important to examine some of the potential problems that may arise. 183 11–16 year old video game players (152 males; 31 females) were recruited from four amusement arcades to answer a computerised questionnaire. Using an analysis similar to Fisher (1992) her results for adolescent fruit machine use were confirmed. However a separation of key variables and the use of a multiple regression analysis showed that of money spent, time spent and impaired choice, only the first was a significant predictor of delinquency. It is suggested that delinquents have higher disposable incomes to spend on their leisure activities. Video game playing and possibly fruit machine gambling appear to be independently associated with delinquency; in video game playing this association is not mediated by dependency. It was argued that a similar methodology should be used in the UK to re-examine Fisher's (1992) conclusions for children who use gaming machines.The authors wish to thank Timezone Amusement Arcades for the generous use of their centres, Colin Davis for programming the questionnaire and Dr. Sung-Mook Hong for statistical advice.     

Dual effects of ‘losses disguised as wins’ and near-misses in a slot machine game

Individually, both near-misses and losses disguised as wins (LDWs) have been seen to exert pro-motivational effects on gambling. However, it is not clear whether both structural characteristics are effective within the same game. Participants (n = 40) played a slot machine simulation. The simulation delivered near-misses, wins and ‘full-misses’. Half the participants also received LDWs that occurred independently of the outcomes on the payline. Valence and motivation ratings were collected after each round. Results showed that the LDW group reported increased valence ratings compared to the no-LDW group. Within the LDW group, trials with LDWs also resulted in increased enjoyment compared to trials without LDWs. We distinguished near-misses falling either side of the payline. Near-misses before the payline (NMB) were rated as more motivational than near-misses after the payline (NMA), whereas NMAs were rated as more aversive than NMBs. These differences between the two near-miss types were exacerbated by LDWs. Results demonstrate LDWs increase the trial-by-trial enjoyment of non-win outcomes. The motivational and hedonic effects of near-misses differed for events either side of the payline, and these differences were exaggerated by the presence of LDWs. Thus, near-misses can retain their effectiveness in complex forms of gambling that also deliver LDWs.     

To pay or to apologize? On the psychology of dealing with unfair offers in a dictator game

Prior research has largely failed to focus on how transgressors can promote trust when having made unfair offers in bargaining. I investigated in the context of receiving an unfair offer in a dictator game when financial compensations and when apologies are most effective in motivating trust behavior by the violated party. I hypothesized that when losses were allocated, the violated party would be motivated to show more trust behavior towards the transgressor when a financial compensation (resulting again in equal final outcomes) relative to an apology was delivered, whereas when gains were allocated, apologies would be more effective in promoting trust behavior than a financial compensation. Results from a laboratory study indeed supported this prediction as such demonstrating the importance of how allocation decisions are framed (i.e., loss or gain) in testing the effectiveness of trust repair strategies (financial compensations vs. apologies).
