Conventional analyses of secularization typically deal with revealed religions and the increasing disenchantment of their adherents with revealed religious doctrines under conditions of rapid industrialization and urbanization. Very little research, however, has dealt with the rise and decline of religiousity or the impact of secularization in social systems organized around a civil religion. This investigation approaches the development of the Bolshevik party in the Soviet Union as an example of a civil religious movement to test Weber's notions of enchantment and disenchantment against the experience of devoted party activists in order to see how increasing industrialization has influenced the civil religion of Marxism-Leninism and the behavior of individual followers of Marxism-Leninism. Hence, this analysis seeks to discover whether or not a dynamic of secularization, perhaps akin to the growing disenchantment among devoted Protestants from the sixteenth through the nineteenth centuries as discussed by Weber, might be found in post-revolutionary communist societies, like the presentday USSR. If such a dynamic of secularization does exist, then the question of civil religious revivalism, or revitalization movements, will be addressed to consider how and where such revivalistic movements might develop within post-revolutionary, secularized communist systems.  相似文献

Guerrilla governments arise where landlord or central government authority has decayed. In such situations, the guerrillas often establish a new implicit social contract with the peasantry, replacing the previous social contract, the abrogation of which has reduced the traditional authorities from legitimate to predatory powers in their relationships with peasants. Guerrillas build up their authority by carrying out three contractual obligations of authority: (1) defense of the people from external enemies; (2) maintenance of internal peace and order; and (3) contributions to the material security of the populace, the last by increasing peasant incomes and by providing health services, literacy training, and sometimes land to rural cultivators. As a result of such activities, peasants often come to perceive guerrillas as the new legitimate authorities in the region. Such authority has decayed, however, where the guerrillas in turn fail to fulfill the obligations of the social contract. Loss of authority can appear when guerrillas fail to defend the peasantry against military attackers, or when guerrillas themselves come to employ terror against the rural populace, thus violating the social contract uniting legitimate authorities and their subjects. This paper concludes with a discussion of the relevance of the study of guerrillas to social movement theory.  相似文献

This article asks how the cultural environment shapes activist claims making. Using data from a grassroots antitoxics/anti-incinerator movement field study, I show how activists modify their political claims as they shift their discussion from the interpersonal level (back region) to the wider public (front region). Each region has distinct constraints and opportunities that shape the construction and potency of activists' claims.
I begin by describing the interrelations between movement frames and the cultural environment; I then argue that the concept of "cultural resonance" captures these interrelations. Next, I describe the front region and back region collective action frames that activists constructed. Despite their denial, they presented claims that differed between regions. I use the ideas of region and cultural resonance to argue that distinct region specific conventions shaped activist frames into conventional styles, forms, and themes. I conclude by discussing processes of intramovement solidarity, and prospects for intermovement cooperation.  相似文献

A shift away from up-or-out, theconventional promotion system in professional servicefirms, has been explained as part of a wider set ofchanges in internal labor market arrangements andmanagement methods. This is investigated empirically in a sample oflarge partnerships in one profession. Up-or-out was usedby less than one-third of the sample of firms but iscommon among the largest firms. Internal reforms to the professional firm do not fully explainits rarity; up-or-out appears to be adaptable to newforms of management and internal labor market policies.This raises a number of questions about the utility of theoretical explanations of how professionalservice firms work or are changing.  相似文献

A twin study explored the possible genetic influences on gambling behavior. Male monozygotic (MZ) twins (n = 42) revealed significantly greater similarity on gambling frequency associated with high-action games than male dizygotic (DZ) twins (n = 50). The heritability estimates for involvement in these types of games among males were moderate and significant. All MZ versus DZ comparisons among males for low-action games were nonsignificant, as were MZ versus DZ comparisons among females (n = 63) for both types of games. The findings suggest that genetic influences may be important in the origins of certain types of gambling by men.  相似文献

Because experiments with Bacillus anthracis are costly and dangerous, the scientific, public health, and engineering communities are served by thorough collation and analysis of experiments reported in the open literature. This study identifies available dose-response data from the open literature for inhalation exposure to B. anthracis and, via dose-response modeling, characterizes the response of nonhuman animal models to challenges. Two studies involving four data sets amenable to dose-response modeling were found in the literature: two data sets of response of guinea pigs to intranasal dosing with the Vollum and ATCC-6605 strains, one set of responses of rhesus monkeys to aerosol exposure to the Vollum strain, and one data set of guinea pig response to aerosol exposure to the Vollum strain. None of the data sets exhibited overdispersion and all but one were best fit by an exponential dose-response model. The beta-Poisson dose-response model provided the best fit to the remaining data set. As indicated in prior studies, the response to aerosol challenges is a strong function of aerosol diameter. For guinea pigs, the LD50 increases with aerosol size for aerosols at and above 4.5 μm. For both rhesus monkeys and guinea pigs there is about a 15-fold increase in LD50 when aerosol size is increased from 1 μm to 12 μm. Future experimental research and dose-response modeling should be performed to quantify differences in responses of subpopulations to B. anthracis and to generate data allowing development of interspecies correction factors.  相似文献

Abstract

People without functional access to a car in countries where private vehicles are the predominant form of transport are at a disadvantage. Alternative modes of travel in such settings often do not meet people's mobility needs, creating barriers to participation in work, education, social activities, sport and leisure, and to accessing basic goods and services. In New Zealand, private vehicles have long been prioritised as the mode of personal transport in land transport planning policy. However, this is beginning to change with policy objectives now including improvement of access and mobility for all, and reduction of social exclusion. Despite this there is very little evidence of the experiences of those with mobility or access problems in New Zealand. This article seeks to provide qualitative data about experiences of transport related social exclusion, the efficacy of alternative modes for people's mobility needs, the impacts of these difficulties on people's lives, and the policy implications of these findings.  相似文献

SWAPCO is a nuclear fuel brokerage company which has managed to survive in a highly competitive niche market for fourteen years. The market is currently declining and the company must develop a strategy for survival and future growth. The case is designed to enable students to think about the effects of a rapidly changing market on a company's business and the effect of changes in the external environment on the company. It leads to discussion of market strategies, the role of government in business, the effects of competition and other external factors in the survival and growth of a business. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

Quantitative microbial risk assessment was used to predict the likelihood and spatial organization of Mycobacterium tuberculosis ( Mtb ) transmission in a commercial aircraft. Passenger exposure was predicted via a multizone Markov model in four scenarios: seated or moving infectious passengers and with or without filtration of recirculated cabin air. The traditional exponential ( k  = 1) and a new exponential ( k  = 0.0218) dose-response function were used to compute infection risk. Emission variability was included by Monte Carlo simulation. Infection risks were higher nearer and aft of the source; steady state airborne concentration levels were not attained. Expected incidence was low to moderate, with the central 95% ranging from 10−6 to 10−1 per 169 passengers in the four scenarios. Emission rates used were low compared to measurements from active TB patients in wards, thus a "superspreader" emitting 44 quanta/h could produce 6.2 cases or more under these scenarios. Use of respiratory protection by the infectious source and/or susceptible passengers reduced infection incidence up to one order of magnitude.  相似文献

The use of graphical methods for comparing the quality of prediction throughout the design space of an experiment has been explored extensively for responses modeled with standard linear models. In this paper, fraction of design space (FDS) plots are adapted to evaluate designs for generalized linear models (GLMs). Since the quality of designs for GLMs depends on the model parameters, initial parameter estimates need to be provided by the experimenter. Consequently, an important question to consider is the design's robustness to user misspecification of the initial parameter estimates. FDS plots provide a graphical way of assessing the relative merits of different designs under a variety of types of parameter misspecification. Examples using logistic and Poisson regression models with their canonical links are used to demonstrate the benefits of the FDS plots.  相似文献
