When randomly assigning participants to experimental roles and the according payment prospects, participants seem to receive “manna from heaven.” In our view, this seriously questions the validity of laboratory findings. We depart from this by auctioning off player roles via the incentive compatible random price mechanism thus avoiding the selection effect of competitive second price auctions. Our experiment employs the generosity game where the proposer chooses the size of the pie, facing an exogenously given own agreement payoff, and the responder is the residual claimant. We find that entitlement crowds out equality seeking and strengthens efficiency seeking. More generally, we find that inducing entitlement for the roles in which participants find themselves makes a difference. Interpreting participants’ willingness to pay for their role as their aspiration level further allows to test satisficing and explore “mutual satisficing.” We find that responder participants apparently do not anticipate proposer generosity in aspiration formation.  相似文献

Bootstrapping has been used as a diagnostic tool for validating model results for a wide array of statistical models. Here we evaluate the use of the non-parametric bootstrap for model validation in mixture models. We show that the bootstrap is problematic for validating the results of class enumeration and demonstrating the stability of parameter estimates in both finite mixture and regression mixture models. In only 44% of simulations did bootstrapping detect the correct number of classes in at least 90% of the bootstrap samples for a finite mixture model without any model violations. For regression mixture models and cases with violated model assumptions, the performance was even worse. Consequently, we cannot recommend the non-parametric bootstrap for validating mixture models.

The cause of the problem is that when resampling is used influential individual observations have a high likelihood of being sampled many times. The presence of multiple replications of even moderately extreme observations is shown to lead to additional latent classes being extracted. To verify that these replications cause the problems we show that leave-k-out cross-validation where sub-samples taken without replacement does not suffer from the same problem.  相似文献

One of the most noticeable aspects of recent studies which examine Irish migration to New Zealand has been the identification of a sizeable contingent of Ulster Protestant settlers within that migrant stream. Their presence has proven to be a complicating factor in how the history of the Irish in New Zealand has been written and has made easy assumptions about the loyalty, identity, politics and ethnicity of that population impossible. This essay surveys the existing literature on New Zealand's Ulster Protestant population across a wide range of subjects while at the same time considering their apparent disappearance as a distinct ethnic grouping in the new world.  相似文献

ABSTRACT

China’s mobility turn has created the world’s largest public rail system, contributing extensively to citizens’ economic, social, and spatial mobility. Concurrently, this technological transformation has introduced many opportunities for individuation, which could potentially challenge the social, collectivistic, and Confucian foundations of China’s sociocultural and political ideology. While the notion that ‘mobility produces culture’ is readily accepted, research on train mobility in China is rare. In this study, we use Albert Bandura’s Model of Triadic Reciprocal Causation to conceptualize mobility as agency. We employ Hermeneutic Content Analysis, a mixed methods framework, to study how this rapidly evolving mobility environment connects to the lives of 31 regular train users living in Beijing. Studying agency in China enables us to systematize the sociocultural models within which mobility practices are embedded and how they manifest. We find that our interviewees embed agentive practices in a cultural model that is intertwined with collectivistic aspirations of the country. Technological developments are thus integrated into existing sociocultural models and political expectations, contradicting existing debates on the fracturing impact of disruptive technologies.  相似文献

The European research project SIREN analysed subjective perceptions and interpretations of changes in working life and their interrelation with political orientations. This article presents the results of the qualitative part of the research in Austria. The findings lead to a better understanding of the appeal to various population groups of rightwing populism and allow an empirical scrutiny of related theses. In particular, the contribution describes, by way of a typology, the variety of reasons as to why people take on authoritarian-exclusivist orientations and accept right-wing populist political propositions. The core question is how subjective perceptions and interpretations of socioeconomic change are transformed into political subjectivity.  相似文献

本文是曼弗雷德·鲍姆(Manfred Baum)教授2008年10月3日在武汉大学哲学学院所作讲演的译稿.文中对康德<道德形而上学>一书划分成"法权论"和"德行论"的来由、理论根据和基础进行了分析,认为康德摧毁了传统的自然法学说,而把法权和德行全都建立在人的自由之上,视为人的义务的内外两方面.同样作为定言命令,康德的法权原则是分析命题,德行原则是综合命题,前者对人的目的不作要求,后者则要求人把人格和人性当作目的.但法权毕竟要以道德为前提和评价标准,而道德本身的评价标准则是从外部合法性向内部行动"转移"而来的,这是一个矛盾.  相似文献

We derive approximating formulas for the mean and the variance of an autocorrelation estimator which are of practical use over the entire range of the autocorrelation coefficient ρ. The least-squares estimator ∑ n −1 i =1ε i ε i +1 / ∑ n −1 i =1ε2 i is studied for a stationary AR(1) process with known mean. We use the second order Taylor expansion of a ratio, and employ the arithmetic-geometric series instead of replacing partial Cesàro sums. In case of the mean we derive Marriott and Pope's (1954) formula, with (n− 1)−1 instead of (n)−1, and an additional term α (n− 1)−2. This new formula produces the expected decline to zero negative bias as ρ approaches unity. In case of the variance Bartlett's (1946) formula results, with (n− 1)−1 instead of (n)−1. The theoretical expressions are corroborated with a simulation experiment. A comparison shows that our formula for the mean is more accurate than the higher-order approximation of White (1961), for |ρ| > 0.88 and n≥ 20. In principal, the presented method can be used to derive approximating formulas for other estimators and processes. Received: November 30, 1999; revised version: July 3, 2000  相似文献

A method for expanding the choices for fits of discrete data is given. The method is very simple: a breakpoint is chosen for the data set on either side of which two separate discrete distributions are fit. Thus, the method is a mixture of two discrete distributions. The method is appealing in light of the ease with which the likelihood equations simplify. For illustrative purposes, the method is used on the data set that motivated its conception.  相似文献
