Near Wins Prolong Gambling on a Video Lottery Terminal

The purpose of the present study was to evaluate whether near wins can prolong gambling activity on a video lottery terminal. In a three-reel game, near wins were operationally defined as two identical symbols followed by a third different symbol. Players in an experimental condition were exposed to 27% near wins in a series of continuous losses, whereas players in a control group were exposed to none. Participants played as long as they wished, and received real money for their wins. The results showed that players in the near win condition played 33% more games than did the control group. The results of this study suggest that near wins can be added to the list of factors that may motivate people to gamble despite the probability of monetary loss.     

Formal strategy in public hospitals

This paper suggests that the difficulties associated with the application of formal strategic planning in public professional service organizations may have been underestimated in much of the literature. A survey of written strategic plans produced by Canadian hospitals showed that these plans were often heavily oriented towards expansion, ambiguous and rather loosely integrated, leading to questions concerning their realism and utility as a basis for strategic decisions. This phenomenon seems symptomatic of the complex (and often highly political) decision making environment faced by hospital administrators (and by managers of other professional service organizations such as universities and social service agencies). It is concluded that the benefits of formal planning may be different and less tangible for these organizations than for private business.     

Pathways to Satisfaction with Work-Life Balance: The Case of Russian-Language Internet Freelancers

In this paper we examine satisfaction with work-life balance among non-standard workers. Using unique data from 6,009 Russian-language internet freelancers, who are typically both autonomous contractors and teleworkers, we make two key contributions. We found evidence to support the demand-resource model among self-employed professionals who typically have autonomy and control over their time, although these processes differ somewhat by gender. We also argue that overall life satisfaction is a significant influence on satisfaction with work-life balance and also acts as a mediator for the influence of some demands and resources on both male and female freelancers’ satisfaction with work-life balance. Implications for future research and social policy are discussed.     

Modeling Infant Speech Sound Discrimination Using Simple Associative Networks

Infants' responses in speech sound discrimination tasks can be nonmonotonic over time. Stager and Werker (1997) reported such data in a bimodal habituation task. In this task, 8‐month‐old infants were capable of discriminations that involved minimal contrast pairs, whereas 14‐month‐old infants were not It was argued that the older infants' attenuated performance was linked to their processing of the stimuli for meaning. The authors suggested that these data are diagnostic of a qualitative shift in infant cognition. We describe an associative connectionist model showing a similar decrement in discrimination without any qualitative shift in processing. The model suggests that responses to phonemic contrasts may be a nonmonotonic function of experience with language. The implications of this idea are discussed. The model also provides a formal framework fer studying habituation‐dishabituation behaviors in infancy.     

Socioeconomic status, sexual behavior, and differential AIDS mortality: evidence from Côte d’Ivoire

Lack of knowledge about differential AIDS mortality seriously hampers the study of the economic impact of AIDS in developing countries. We derive HIV infection risk differentials by age, education, and other microeconomic characteristics using the Ivorian Demographic and Health Survey. Our model is based on econometrically estimated equations using commonly available variables, therefore it can be used whenever such a survey is available but there is no representative information about HIV infection by socioeconomic group. For instance, we found that educated people have a higher risk of HIV infection, because they are more likely to have several sexual partners. However, this effect is partly offset by a higher probability of condom use relative to less educated people. The identification of the socioeconomic characteristics of low and high risk groups seems indispensable to set up adequate AIDS prevention and therapy policies in developing countries.

Similarity perceptions in investor reactions to acquisition announcements

We contribute to an improved understanding of investor reactions to acquisition announcements by building on the recent research in cognitive psychology that distinguishes between the following two types of cognitive similarity assessments: taxonomic and thematic similarity. We theorize and find that investor reactions to taxonomic acquisitions, where synergies are easier to comprehend, are generally more positive than investor reactions to thematic acquisitions, which require higher cognitive processing. We argue that this effect is driven by the cognitive processing of investors, instead of “true” synergy, since the more negative announcement returns for thematic deals reverse a few days after the announcement, converging with the announcement returns of taxonomic deals. Moreover, we find that attempts by the acquiring company to help investors assess thematic acquisitions do not seem to be effective at eliminating this effect and instead appear to aggravate investor suspicion. Overall, our findings contribute to the emerging behavioral perspective of investor reactions to acquisition announcements.     

Estimating and testing zones of abrupt change for spatial data

We propose a method for detecting the zones where a variable irregularly sampled in the plane changes abruptly. Our general model is that under the null hypothesis the variable is the realisation of a stationary Gaussian process with constant expectation. The alternative is that the mean function presents abrupt changes. We define potential Zones of Abrupt Change (ZACs) by the points where the gradient, estimated under the null hypothesis, exceeds a determined threshold. We then design a global test to assess the global significance of the potential ZACs, an issue missing in all existing methods. The theory that links the threshold and the global level is based on asymptotic distributions of excursion sets of non-stationary χ ² fields for which we provide new results. The method is evaluated by a simulation study and applied to a soil data set in the context of precision agriculture.
