An experiment designed to test whether experimenter observation influences play of the ultimatum game led to a comparison of proportions of perfect equilibria obtained under different conditions. Our analysis features a Bayesian approach to this comparison. Our method extends recent work in the nonparametric Bayesian analysis of bioassay problems when the prior constrains the form of the potency curve. Sampling-based approaches to calculating posterior features of interest are used and discussed. We conclude that experimenter observation has a small influence but not enough to account for most of the deviation from perfect-equilibrium play. 相似文献

A form of the distribution function of ratios of linear combinations of order statistics of samples from an exponential distribution is given. From the distribution, tables of percentage points of the statistic for α = .05, .95, and n = 3(1)50, and for censoring up to five observations are presented. Use of the tables is made to find critical values of the most powerful scale and location invariant test of exponentiality against uniformity, and also to find critical values for a test of outliers in an exponential population. 相似文献

An algorithm is developed for calculating the probability distribution of the number of matches between two specified rows of a matrix of zeroes and ones. Cases covered include row totals fixed, column totals fixed, and column totals and the two specified rows' totals fixed. The results are applied to presence-absence data on six species of ground finches on 23 Galàpagos islands and two constructed examples. 相似文献

AbstractA major concern in the social sciences is lack of replication of previous studies. An important methodological concern in the social sciences is the ability to determine effect sizes in addition to statistical significance levels. Effect sizes cannot be easily calculated in the absence of sufficient data; usually standard deviations are needed. If standard deviations are not available, how can they be estimated? Various proposals have been offered to solve this question. One solution is to divide the range (maximum–minimum) by four; a variety of more complicated solutions, based on sample size or the skew of the variable’s distribution, have been suggested (Schumm, Higgins, et al., 2017). Here, 30 cases involving the demographic variable of age, from 23 articles published in Marriage & Family Review between 2016 and 2017, are assessed to replicate the previous report of Schumm, Higgins et al. (2017). Our results indicated that both linear and power functions significantly predicted the size of standard deviations, with larger samples featuring smaller standard deviations. Aside from sample size, the best solution appears to be to divide the range by 4.5–5.0; although for very small samples (N?<?50), it is probably better to divide by 3.5–4.0 whereas for larger samples, especially those that involve higher levels of skew, it may be better to divide by 5.0 or higher. The Wan et al. (2014) estimation procedure appears to be approximately a power function of sample size. For samples up to several thousand in size, the range of divisors appears to run between 3.0 and 8.0, extremes that could be used to determine the largest or smallest possible standard deviations, respectively. Values far below 3.0 or above 8.0 may reflect typographical errors in data reports or possibly be evidence of artificially generated data, if not scientific fraud. When a variable is split into subsamples, its standard deviations should usually increase for the subsamples compared with the total sample. Similar assessments remain in progress for non-demographic variables in social sciences. 相似文献

Summary. We introduce a discrete time model for electricity prices which accounts for both transitory spikes and temperature effects. The model allows for different rates of mean reversion: one for weather events, one around price jumps and another for the remainder of the process. We estimate the model by using a Markov chain Monte Carlo approach with 3 years of daily data from Allegheny County, Pennsylvania. We show that our model outperforms existing stochastic jump diffusion models for this data set. Results also demonstrate the importance of model parameters corresponding to both the temperature effect and the multilevel mean reversion rate. 相似文献

With the resurgence of union organizing during the 1990s, a new scholarship about the labor movement has emerged, documenting and explaining this new social movement unionism. Literature on the culture of work is well developed while, generally speaking, in the scholarship about the labor movement, culture is an underdeveloped analysis. In this article, we look at the culture of market fundamentalism as the dominant way of thinking and explaining work and labor in the United States. Market fundamentalism has emerged at the same time that women and immigrants have become much more numerous among U.S. workers, and they have brought with them new cultural emphases at work and among unions. In response to market fundamentalism and with the activism of women and immigrants among others, unions have transformed their own culture toward social movement unionism and have pushed for a new culture of work. 相似文献

The special June 1999 issue of The Career Development Quarterly that dealt with school‐to‐work transitions was an admirable attempt to link theory to practice. However, both the theories used and the practices suggested failed to take into account the special concerns of cultural minorities. Suggestions for improving theory and practice to make them more culturally sensitive are made in this reaction. 相似文献

Family environments of married male members of Gamblers Anonymous (GA) and married female members of GamAnon were measured with the Family Environment Scale (FES), a measure of 10 characteristics of family life. The total sample of 86 included 50 male GA and 36 female GamAnon members. GA and GamAnon groups did not differ from each other. However, the short-term GA group reported greater dissatisfaction than controls on five personal growth dimensions. The long-term GA group reported less Conflict than controls. Both short-term and long-term GamAnon groups reported less satisfaction than normal controls on personal growth dimensions. A composite measure of social support demonstrated improvement with duration of abstinence for gamblers but not for spouses. Results suggest improvement in family environment for male pathological gamblers with length of gambling abstinence but less improvement for wives.The authors wish to thank Mr. Les Franklin for assistance with data coding. 相似文献

A group of 22 parents of adolescent sexual offenders (PASO) was compared with a group of 19 normal controls (NC) and 10 clinical controls (CC) on demographic, developmental, personal adjustment and family environment variables. The assessment protocol included the General Health Questionnaire‐12, the Culture‐Free Self‐Esteem Inventory, the Child Behaviour Checklist, the Family Assessment Device, the Parent Satisfaction Scale and the Multidimensional Scale of Perceived Social Support. Compared with clinical and normal controls, more parents in the PASO group reported that they had been arrested or charged for a criminal offence; had personally experienced child abuse; and more of their adolescents had experienced child abuse, with emotional abuse being the most common form of abuse for both parents and adolescents. Compared with clinical and normal controls, more adolescents of parents in the PASO group had witnessed parental drug or alcohol abuse and had been placed in care outside their home. While parents in the PASO group did not differ from clinical or normal controls in terms of personal adjustment, their adolescents had significantly more internalizing behaviour problems than normal controls, whereas adolescents of parents in the clinical control group had significantly more externalizing behaviour problems than normal controls. Compared with normal controls, parents in both the PASO and clinical control groups reported more difficulties with general family functioning, roles, affective responsiveness, affective involvement and behaviour control and lower levels of parental satisfaction. However, the groups did not differ significantly in their levels of perceived social support. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献
