Drawing on Bonacich's split market theory, the work of Hechter and Blalock on ethnic conflict, and the literature on social movements, the authors develop a model of factors producing conflict between native and immigrant workers. The model identifies the relative size of the immigrant group, the growth of the immigrant population, the desirability of jobs held by immigrant workers, economic conditions, the development of racist ideology among native workers, and the organization of native workers as factors possibly explaining the frequency of incidents of overt ethnic conflict and efforts to institutionalize discrimination through government action. The model is assessed by examining the situation of Chinese immigrants in California between 1849 and 1882. The data suggest that poor economic conditions, a well-developed racist ideology, and well-organized native workers best explain incidents of ethnic conflict and successful efforts to obtain discriminatory government action. 相似文献

It is argued that the anthropological approach, as used by Armstrong and Harris, has not generated any breakthrough in the study of soccer hooliganism. In particular, it is suggested that their use of a commonsense rather than a sociological concept of violence vitiates their analysis in several ways, contributing above all to substantial inconsistencies between some of their own empirical data and their general conclusions concerning levels of soccer-related violence. It is also contended that their critique of the ‘figurational’ or ‘process-sociological’ approach followed by the Leicester researchers is based on a confused misrepresentation of that approach. Specifically it is argued (i) that Armstrong and Harris fail to recognize the wide range of methods, including extensive participant observation, used by the Leicester group, (ii) that their attempt to cast doubt on the Leicester group's contention that the core football hooligans come predominantly from the ‘rougher’ sections of the working class is based on nothing more than a priori speculation. In this connection, Armstrong and Harris themselves provide no reliable data on the social class of soccer hooligans in Sheffield, and they seem unaware of the fact that several different sources of data appear to confirm the finding of the Leicester group, (iii) they have misunderstood both the terminology and the reasoning of the Leicester group concerning the ‘rougher’ sections of the working class and their relationship to football hooliganism. 相似文献

Studies have shown that exposure to discrimination increases the probability that African American adolescents will engage in delinquent behavior, especially acts of violence. The present study extended this research by examining the extent to which supportive parenting buffers a youth from these deleterious consequences of discrimination. Analyses based upon two waves of data from a sample of 332 African American adolescent males and their caretakers supported this hypothesis. Further the results indicated that there are two avenues whereby supportive parenting reduces the probability that discrimination will lead to violence. First, supportive parenting decreases the chances that discrimination will lead to anger and a hostile view of relationships. Second, supportive parenting lowers the risk that anger or a hostile view of relationships, when they develop, will result in violence. 相似文献

We investigate whether seasonal-adjustment procedures are, at least approximately, linear data transformations. This question was initially addressed by Young and is important with respect to many issues including estimation of regression models with seasonally adjusted data. We focus on the X-11 program and rely on simulation evidence, involving linear unobserved component autoregressive integrated moving average models. We define a set of properties for the adequacy of a linear approximation to a seasonal-adjustment filter. These properties are examined through statistical tests. Next, we study the effect of X-11 seasonal adjustment on regression statistics assessing the statistical significance of the relationship between economic variables. Several empirical results involving economic data are also reported. 相似文献

In this paper we provide a comprehensive Bayesian posterior analysis of trend determination in general autoregressive models. Multiple lag autoregressive models with fitted drifts and time trends as well as models that allow for certain types of structural change in the deterministic components are considered. We utilize a modified information matrix-based prior that accommodates stochastic nonstationarity, takes into account the interactions between long-run and short-run dynamics and controls the degree of stochastic nonstationarity permitted. We derive analytic posterior densities for all of the trend determining parameters via the Laplace approximation to multivariate integrals. We also address the sampling properties of our posteriors under alternative data generating processes by simulation methods. We apply our Bayesian techniques to the Nelson-Plosser macroeconomic data and various stock price and dividend data. Contrary to DeJong and Whiteman (1989a,b,c), we do not find that the data overwhelmingly favor the existence of deterministic trends over stochastic trends. In addition, we find evidence supporting Perron's (1989) view that some of the Nelson and Plosser data are best construed as trend stationary with a change in the trend function occurring at 1929. 相似文献

Nonparametric regression is considered where the sample point placement is not fixed and equispaced, but generated by a random process with rate n. Conditions are found for the random processes that result in optimal rates of convergence for nonparametric regression when using a block thresholded wavelet estimator. Previous results on nonparametric regression via wavelets on both fixed and random sample point placement are shown to be special cases of the general result given here. The estimator is adaptive over a large range of Hölder function spaces and the convergence rate exhibited is an improvement over term-by-term wavelet estimators. Threshold selection is implemented in a data-adaptive fashion, rather than using a fixed threshold as is usually done in block thresholding. This estimator, BlockSure, is compared against fixed-threshold block estimators and the more traditional term-by-term threshold wavelet estimators on several random design schemes via simulations. 相似文献

A wavelet method is proposed that reduces function estimation error and provides smooth reconstructions, while still estimating jumps in the function well. It is based on analyzing multiple dilated versions of the sampled function. In simulation studies, the estimator exhibits low mean squared errors without sacrificing smoothness or jump detection ability when compared to other wavelet methods. 相似文献

ABSTRACT The illicit drug crops opium and coca are conventionally regarded as sources of instability, an ‘evil’ that breeds fragility and violence. Fragile states are supposed to be most vulnerable to their production and consequent harms. Yet by looking into the local contexts of the world’s leading opium and coca producers – Afghanistan, Myanmar, Colombia and Bolivia – these illicit crops are found to also be sources of stability, even drivers of economic growth. They enable marginalized communities and territories abandoned by the state to be reinserted into national and global markets. Within so-called ‘fragile’ and conflict-affected areas are displaced and dispossessed households adopting innovative and unorthodox strategies for coping and survival in changing and insecure environments. This paper maps out an approach, useful for examining the resilience that has emerged amidst violence and uncertainty in illicit-crop-producing territories, and which can hopefully tackle the continuing disconnect between drugs and development policy. 相似文献
