This paper examines deprogramming, a multi-faceted form of derecruitment from unpopular religious groups (“cults”) developed in the United States and then spreading to other nations, as a form of social control of new religious movements. The early history of deprogramming in the United States is discussed, and then its more recent application in Japan against members of the Unification Church is detailed. A continuum is presented that has self-help remedies at one end, and governmental repression at the other. Self-help forms of deprogramming are illustrated mainly by the United States which has First Amendment protections for religious groups which afford some protection from governmental intervention. Governmental forced derecruitment is illustrated by China’s effort to stamp out the Falun Gong through a very systematic official governmental program involving many institutions operating with full support of the government and the Chinese Communist Party. In between these extremes are cases such as Japan’s social control efforts, and some within the United States, where governmental officials and agencies turn a “blind eye” to self-help remedies, allowing them to operate, or even engage in covert activities to suppress unpopular religious groups.  相似文献

In forensic evidence, the identification and quantitation of gamma-hydroxybutyric acid (GHB) in "spiked" beverages is challenging. In this report, we present the analysis of common alcoholic beverages found in clubs and bars spiked with gamma-hydroxybutyric acid (GHB) and gamma-butyrolactone (GBL). Our analysis of the spiked beverages consisted of using (1)H NMR with a water suppression method called Presaturation Utilizing Relaxation Gradients and Echoes (PURGE). The following beverages were analyzed: water, 10% ethanol in water, vodka-cranberry juice, rum and coke, gin and tonic, whisky and diet coke, white wine, red wine, and beer. The PURGE method allowed for the direct identification and quantitation of both compounds in all beverages except red and white wine where small interferences prevented accurate quantitation. The NMR method presented in this paper utilizes PURGE water suppression. Thanks to the use of a capillary internal standard, the method is fast, non-destructive, sensitive and requires no sample preparation which could disrupt the equilibrium between GHB and GBL.  相似文献

The process of decomposition of bodies in the marine environment is poorly understood and almost nothing is currently known about the microorganisms involved. This study aimed to investigate the microbes involved in decomposition in the sea and to evaluate the potential use of marine bacterial succession for postmortem submersion interval (PMSI) estimation, for which there is currently no reliable method. Partial pig remains were completely submerged during autumn and winter and were regularly sampled to document marine bacterial colonisation and the changes in community composition over time. Five stages of decomposition were recognised, some of which exhibited characters specific for partial carrion. Marine bacteria rapidly colonised the submerged remains in a successional manner. Seasonal differences were observed for the rate of decomposition and also for several groups of colonising bacteria. Marine bacteria specific for particular PMSIs were identified. This study provides an insight into the involvement of saprophytic marine bacteria in the decomposition of mammalian remains in the sea and is the first to explore the use of marine bacterial colonisation and succession as a novel tool for PMSI estimation. We propose that with further study, marine bacterial succession will prove useful for determination of the length of time a body may have been immersed in a marine environment.  相似文献

This study explores the prevalence and correlates of past-year physical violence against women in slum and nonslum areas of urban Bangladesh. The authors use multivariate logistic regression to analyze data from the 2006 Urban Health Survey, a population-based survey of 9,122 currently married women aged between 15 and 49 who were selected using a multistage cluster sampling design. The prevalence of reported past-year physical spousal violence is 31%. Prevalence of past-year physical spousal violence is higher in slums (35%) than in nonslums (20%). Slapping/arm-twisting and pushing/shaking/ throwing something at the women are the most commonly reported acts of physical abuse. Multivariate analysis shows that the risk of physical spousal abuse is lower among older women, women with post-primary education, and those belonging to rich households and women whose husbands considered their opinion in decision making. Women are at higher risk of abuse if they had many children, believe that married woman should work if the husband is not making enough money, and approve wife-beating norms. This study serves to confirm the commonness of physical spousal abuse in urban Bangladesh, demonstrating the seriousness of this multifaceted phenomenon as a social and public health issue. The present findings suggest the need for comprehensive prevention and intervention strategies that capitalize on the interplay of individual and sociocultural factors that cause physical spousal violence. Our study adds to a growing literature documenting domestic violence against women in urban areas of developing south Asian nations.  相似文献

This article debates and defends the lawfulness of a randomised controlled trial of compulsory outpatient treatment under the mental health legislation for England and Wales. The trial is designed to compare the outcomes for patients of their treatment under the new Community Treatment Order (CTO) regime with their treatment under the older leave scheme - the two main forms of compulsory care in the community now authorised by the revised Mental Health Act 1983. The methods for the trial involve the random allocation of some patients between the two schemes, when they are considered by their Responsible Clinicians to be eligible for some form of compulsory outpatient care. The main question we consider is the lawfulness of that aspect of the methods. Can a carefully selected group of patients be allocated at random between the two regimes to permit an evaluation to proceed? Or would that involve some departure from the decision-making criteria specified by law? We argue that a group of patients can be identified who meet - simultaneously - the tests for treatment under both the CTO and the leave schemes. Those patients could then be allocated lawfully to treatment under either scheme. This opens the door, we argue, to their random allocation between the two schemes for the purposes of the research. In reaching this conclusion, we explain the methods and aims of the trial and closely compare the respective features of the leave and CTO regimes.  相似文献

Since the mid-1990s, the index crime rate has steadily decreased while the rate for Part II offenses has increased. The current study examines these differences from 1990 to 2004 using arrest rate data from the 35 largest cities in the state of Texas. Cluster regression analyses is employed to examine the effect of city size and city location, whether the city is part of a larger metropolitan area or “stand-alone,” to explain variation in juvenile and adult arrest rates by category of offense (violent, property, Part II) while controlling for the influence of social disorganization variables. Findings indicate that differences exist in the arrest rates for almost all types of offenses in mid-size versus very large cities. Contrasting adult versus juvenile arrest rates, city size and city location offer limited explanation for variation over time. Implications of these findings are discussed in the context of suggested policy and research directions.  相似文献

Concerns about the duration of China??s growth and hence the question of a permanent significant contribution of China to world economic growth relate, amongst other things, to the problem of reducing regional disparity in China. While China??s high average growth is driven by a small number of rapidly developing provinces, the majority of provinces have experienced a more moderate development. To obtain broad continuos growth it is important to identify the determinants of provincial growth. Therefore, we introduce a stylized model of regional development which is characterized by two pillars: (1) International integration indicated by FDI and/or trade lead to imitation of international technologies, technology spill overs and temporary dynamic scale economies, and (2) domestic factors indicated by human and real capital available through interregional factor mobility. Using panel data analysis and GMM estimates our empirical analysis supports the predictions from our theoretical model of regional development. Positive and significant coefficients for FDI and trade support the importance of international integration and technology imitation. A negative and significant lagged GDP per capita indicates a catching up, non steady state process across China??s provinces. Highly significant human and real capital identifies the importance of these domestic growth restricting factors. However, other potentially important factors like labor or government expenditures are (surprisingly) insignificant or even negative. Extending the model using an unbalanced panel leads to a positive effect of the quality of governance and institutions on development.  相似文献

This article reviews the history of executive budgeting in the United States a century after President William Howard Taft's Economy and Efficiency Commission proposed an executive budget. This history, the authors argue, does not suggest that giving more budget power to the president will improve budget outcomes. Instead, what is needed is more cooperation between the branches of government and a better‐educated public—goals that were shared by budget reformers when the Taft report was published.  相似文献
