The aim of the current study was to examine the different EGM environmental preferences of recreational compared to problem gamblers in Australia. Semi-structured interviews were conducted with 59 EGM gamblers recruited from EGM venues in Queensland and New South Wales, Australia. Interview data were organised using a thematic analysis into 42 major environmental features that gamblers identified as being of importance in choosing where and what to play. The frequency with which certain environmental characteristics were mentioned was analysed quantitatively, along with demographic information and PGSI status. Results showed that the most common reason for selecting the gambling platform was social, and in-venue gambling was largely but not exclusively preferred for this reason. The most frequently mentioned reason for selecting the provider was based on being close to home and enjoying the service at the venue. Finally, games were frequently selected based on features such as free spins, minimum bet sizes, graphics and in-game sounds. The survey results identified that persons experiencing gambling problems more frequently mentioned the availability of a number of game choices and the perceived potential for winning as important aspects in choosing an EGM environment. This study provides some preliminary evidence on what features of the EGM environment are important to players, and most conducive to safer gambling environments. The findings from this study will inform policy initiatives for player protection through the development of safer EGM gambling environments.L’objectif de la présente étude était d’examiner les différentes préférences quant à l’environnement d’un site d’appareils de loterie vidéo entre les joueurs qui font un usage récréatif de ces appareils et les joueurs à problèmes en Australie. Des entrevues semi-dirigées ont été menées auprès de 59 utilisateurs d’appareils de loterie vidéo recrutés dans divers lieux où de tels appareils sont accessibles dans le Queensland et en Nouvelle-Galles-du-Sud (Australie). Une analyse thématique des données des entrevues a permis d’organiser les données en 42 grandes caractéristiques environnementales ayant de l’importance pour les joueurs dans le choix d’un jeu et de l’endroit où jouer. La fréquence dans laquelle certaines caractéristiques environnementales ont été mentionnées a fait l’objet d’une analyse quantitative, de même que les données démographiques et l’indice de gravité du jeu problématique des joueurs. Les résultats indiquent que les raisons les plus communes pour le choix d’une plateforme de jeux étaient d’ordre social, et que, par conséquent, la préférence était en grande partie, mais non exclusivement, accordée aux espaces de jeu situés dans des lieux publics. La raison la plus fréquemment mentionnée pour le choix d’un lieu de jeu était la courte distance de la résidence et les services offerts par l’établissement. Enfin, le choix des jeux reposait généralement sur des caractéristiques comme l’offre de parties gratuites, le montant minimal des mises et les effets visuels et sonores du jeu. Les résultats de l’enquête indiquent que les personnes aux prises avec des problèmes de jeu mentionnaient plus fréquemment, parmi les caractéristiques importantes pour le choix d’un site d’appareils de loterie vidéo, l’éventail des jeux offerts et la perception d’une plus grande possibilité de gagner. Cette étude fournit de manière préliminaire des données probantes sur les caractéristiques environnementales des sites d’appareils de loterie vidéo qui sont importantes pour les joueurs et sur celles qui sont les plus propices à la création d’environnements de jeu sécuritaires. Les conclusions de l’étude éclaireront l’élaboration d’initiatives stratégiques visant à protéger les joueurs par l’établissement de sites d’appareils de loterie vidéo sécuritaires.

Zn1-xCoxO (0 < x < 14.6) diluted magnetic semiconductor coatings have been obtained by reactive DC magnetron sputtering of metallic Zn and Co targets at high pressure and high temperature. The coatings structural properties have been investigated by X-ray diffraction. All as-deposited coatings are crystalized in ZnO structure and neither traces of metallic nor oxide Co-rich clusters were detected in the films. The temperature dependence of the magnetization shows a paramagnetic Curie-Weiss behavior with antiferromagnetic interaction due to the associated spins and simple paramagnetic curie behavior of isolated free spins.

This study investigates modes of moving visitors in a tourist location using a location-based service. Two field experiments were conducted at a zoo using real visitors as participants and behavior-based dependent variables. Experiment 1 included 2,618 visitors and investigated whether the amount of rewards, in the form of free spins on a wheel of fortune, would affect the choice to move to this wheel and claim the offered rewards. The choice of using this offer was used as a dependent variable. Experiment 2 included 970 visitors and investigated whether labelling participants with a fitting trait led them to move to a certain location. Geographical data using iBeacon logging was used as the dependent variable. Using chi-square tests for independence, we causally show that both the reward and the label had a positive and significant effect on moving the visitors to the targeted location.

Automatic transmissions use one-way clutches and regular clutches to control gear shifts. Regular one-way clutch locks in one direction and free spins (freewheeling) in the other direction and thus provides good shift quality. However, a clutch is needed if the freewheeling direction needs to be locked. The advantage of a selectable one-way clutch (SOWC) is that it can be designed to act like a regular one-way clutch, fully freewheels or locks in both directions. In the GM six-speed transmissions, there is one one-way clutch which is accompanied by a clutch CB1R to control between 1st gear and reverse direction. The study is to replace the one-way clutch and CB1R clutch with simply one selectable one-way clutch in GM 6-speed transmissions (1). This will eliminate one transmission clutch, reduce weight and cost, and improve transmission efficiency. The proposed design of transmission is applied to a GM SUV and a GM passenger vehicle. Different from a regular clutch, which can be applied with force/pressure from high slippage to lock-up between two elements, a selectable one-way clutch can only be applied to a lock-up position when the slippage between two elements is near zero speed. Also, an SOWC can only be released when there is no torque or force carried by the clutch while a regular clutch can be easily released by dropping the applied force/pressure. These requirements impose challenges of the control strategies of the SOWC, especially during the scenarios such as 2–1 engine idle downshift (engine braking) and 1–2 upshift (coasting). This paper reviews hardware design, vehicle implementation, and focuses on control of the selectable one-way clutch. Vehicle results demonstrate static and rolling garage shifts, 1–2 upshifts, 2–1 and coast downshifts. Also demonstrated is the successful application of engaging 1st gear engine braking with the SOWC. This control involves coordination between the engine speed and SOWC slip speed, and the apply/release of the device.
