Identification of local clusters for count data: a model-based Moran's I test

We set out I_DR as a loglinear-model-based Moran's I test for Poisson count data that resembles the Moran's I residual test for Gaussian data. We evaluate its type I and type II error probabilities via simulations, and demonstrate its utility via a case study. When population sizes are heterogeneous, I_DR is effective in detecting local clusters by local association terms with an acceptable type I error probability. When used in conjunction with local spatial association terms in loglinear models, I_DR can also indicate the existence of first-order global cluster that can hardly be removed by local spatial association terms. In this situation, I_DR should not be directly applied for local cluster detection. In the case study of St. Louis homicides, we bridge loglinear model methods for parameter estimation to exploratory data analysis, so that a uniform association term can be defined with spatially varied contributions among spatial neighbors. The method makes use of exploratory tools such as Moran's I scatter plots and residual plots to evaluate the magnitude of deviance residuals, and it is effective to model the shape, the elevation and the magnitude of a local cluster in the model-based test.     

Now the Orgy Is Over

Based on six months of ethnographic fieldwork, this study explores the intersections between embodied flesh and digital (re)presentations by examining how participants experience virtual sex on Second Life. We explore how and to what extent Second Life avatars mediate personal desires and fantasies with others who, collaboratively, construct sexual adventures in forms of playful deviance that allow for the emergence of secret sexual selves, as well as how those sexual adventures are ultimately fashioned and experienced in a “diffused life” that is neither of Second Life nor of first but a tightly bound combination of the two. Despite the enormous freedom of Second Life residents for seemingly boundless creative self‐expression, we conclude that these experiences are more bound to and confined within disciplined practices than they first appear.     

Modified classification and regression tree splitting criteria for data with interactions

This paper proposes modified splitting criteria for classification and regression trees by modifying the definition of the deviance. The modified deviance is based on local averaging instead of global averaging and is more successful at modelling data with interactions. The paper shows that the modified criteria result in much simpler trees for pure interaction data (no main effects) and can produce trees with fewer errors and lower residual mean deviances than those produced by Clark & Pregibon's (1992) method when applied to real datasets with strong interaction effects.     

理性选择与越轨行为——地方政府挪用财政支农资金现象分析

某利益方,围绕某个农业项目,以合理的名义向上级追加支农资金,堵住下级的配套基金,截流上级划拨资金到本级,其核心和本质是把其他利益方的资金转移到本级政府使用,是理性选择,也是越轨行为。文章运用经济学和社会学的理论分析了产生这一结果的逻辑过程,在此基础上提出相关建议。     

西方越轨社会学研究的历史、现状与趋势

西方越轨社会学的发展 ,经历了以迪尔凯姆为代表的开创阶段、以默顿为代表的正统越轨社会学阶段和以标签学派为代表的新越轨社会学阶段 ,研究对象也从违规行为转变为社会定义和标签。依据研究对象、理论内容和逻辑结构 ,可以将西方越轨社会学划分为结构功能、社会解组、亚文化群、社会控制、标签、日常生活方法、冲突等七大流派。预测其未来发展趋势 ,中上阶级违规问题、单位违规问题、跨学派研究和国际比较研究等将成为重要研究领域 ,而社会控制学派和冲突学派将上升为主导学派     

Reclothing the Emperor: The Swimming Pool as a Negotiated Order

This article examines the unspoken rules, routines, and rituals of the swimming pool, using ideas from negotiated order theory, Foucault, Goffman's dramaturgical theory, and symbolic interactionism. It identifies three sets of social norms: respect for personal space, respect for individuals' disciplinary regimes, and the desexualization of encounters. I show how these rules are (normally) followed or (occasionally) breached through various rituals, and examine the consequences for interaction order. The tale of “The Emperor's New Clothes” is used analogously to explain why actors cannot consciously attend to their precarious construction of reality, yet remain poised to defend it.     

Anomie Among European Adolescents: Conceptual and Empirical Clarification of a Multilevel Sociological Concept1

Anomie is a complex, dynamic concept that refers simultaneously to a social state and an individual state of mind. Generations of sociologists have attempted to clarify, extend, and measure the concept at various levels of analysis. This article summarizes these developments around the twin concepts of exteriority and constraint. Exteriority refers to experiencing the social world as an objective, predictable reality, while constraint refers to the extent to which one experiences a personal commitment to the demands and expectations of society. The Anomie Scale of Exteriority and Constraint (ASEC) is presented and tested across various psychological and social outcomes among adolescents in 18 European countries. Exteriority is found to be primarily associated with more depression and less self‐esteem, while constraint is associated with a lower probability of daily smoking, illicit drug use, truancy, and suicide attempts. Societal anomie is higher in eastern European countries and it has a strong negative correlation with GDP per capita and a marginally positive correlation with GDP growth. Societal anomie is also associated with higher baseline levels of depression, self‐esteem, and illicit drug use. These results lend strong support to the theoretical construct of anomie as exteriority and constraint.     

From the attic of theAmerican Journal of Sociology: Unusual contributions to American sociology, 1895–1935

This study examines articles published in theAmerican Journal of Sociology (AJS) from its inception in 1895 through 1935 in a search for contributions that have escaped the attention of most contemporary sociologists. The articles reviewed here provide a glimpse of a less well-known, and sometimes more unseemly, side of American sociological history. My primary focus is on the criticism of the emergent discipline, the extraordinary diversity of thought found in the earlyAJS, and antiquated or prescient ideas, particularly in the fields of deviance, race, and gender.     

Race,Ethnicity, and Deviance: A Study of Asian and Non-Asian Adolescents in America

This study shows that Asian American adolescents commit less deviance in the form of school misbehavior than white, black, Hispanic, or Native American adolescents. Social control and social learning theories receive support as the observed differences are explained primarily by race/ethnic differences in family backgrounds and school bonding. These variables' explanatory ability tends to be invariant across four regional groups of Asian Americans. This study applies OLS regression to self-reported data from a nationally representative sample.     

An exact decomposition for a class of exponential dispersion models: Application to sequential testing

We define the Wishart distribution on the cone of positive definite matrices and an exponential distribution on the Lorentz cone as exponential dispersion models. We show that these two distributions possess a property of exact decomposition, and we use this property to solve the following problem: given q samples (y_il,… y_iNj), i = l,…,q, from a N(μ_i,Σ_i,) distribution, test H:Σ₁ = Σ₂ = … = σ_q. Using the exact decomposition property, the classical test statistic for H, involving q parameters p_i = (N_i, - l)/2, i = 1,…,q, is replaced by a sequence of q - l test statistics for the sequence of tests H_i,:σ₁ =σ₂ = … =σ_i given that H_i-1 is true, i = 2,…,q. Each one of these test statistics involves two parameters only, p._i-1 = p₁ + … + p_i-1 and p_i. We also use the exact decomposition property to test equality of the “direction parameters” for q sample points from the exponential distribution on the Lorentz cone. We give a table of critical values for the distribution on the three-dimensional Lorentz cone. Tables of critical values in higher dimensions can easily be computed following the same method as in dimension three.
