RICHARD BRITNELL 《Journal of historical sociology》1993,6(4):359-376
Abstract Marx's account of the transition from feudalism to capitalism is usually handled too narrowly in discussions of the later Middle Ages. When its full scope is taken into account the period 1300–1530 is shown to be more a period of arrested development than one of critical importance. The period 1000–1300 showed a much greater shift towards capitalism. By implication, the transition needs analysing as a much longer process than most traditional accounts imply. The article also queries the coherence of accounts of late medieval change that refuse to give autonomous weight to declining population as a cause of social change. 相似文献

HEALTH CARE, INSURANCE, AND THE CONTRACT CHOICE EFFECT 总被引:1,自引:0,他引:1
This article explores the interdependence between the individual consumer's demand for medical care and choice of health insurance coverage, with emphasis on its implications for demand behavior and empirical analysis. We show that an increase in the price of medical care has two effects on demand, the usual response of reduced quantity demanded and a health insurance contract choice effect resulting from the consumer's incentive to change insurance plan. The contract choice effect, widely neglected in studies of medical care demand, alters both the quantitative and qualitative predictive properties of the consumer's demand for medical services.

Sport and globalization: transnational dimensions 总被引:1,自引:0,他引:1
Abstract The aims of this special issue are to both raise the social scientific status of sport and to advance understanding of transnational processes through the role of sport in global change. The Introduction argues that sport, like globalization, can be understood in transdisciplinary terms, and the papers included contributions informed by sociology, anthropology, political sciences and history. As well as placing the issue in the context of recent studies of sport and globalization, the Introduction outlines the seven papers. Placed together they move from analyses of broader globalizing and multi‐sport issues towards consideration of how transnational processes impact upon individual sports – with examples from cricket, baseball and association football – ending with regional and national dimensions. 相似文献

INNUMERACY ABOUT MINORITY POPULATIONS 总被引:1,自引:0,他引:1
We use a small but nationally representative sample to investigatethe sources of innumeracy regarding the proportion of blacks,Hispanics, and Jews in the U.S. population. In addition to anumber of standard demographic differences, we find that overestimatesare closely related to region as well as to the density of thelocal black/Hispanic population. The extent to which minoritypopulations are perceived as a kind of threat is also relatedto perceived proportions, though the direction of causalitycannot be determined. We discuss the meaningfulness of thesepopulation estimates and speculate on whether trying to improvethem would alter attitudes toward minorities. 相似文献

Polls taken in late 1980 and 1984 varied by up to 20 pointsin the spread they reported between Democratic and Republicanidentifiers. We found three systematic and sizable differencesacross polls: polls that sample only voters, polls that emphasize"today" or the present in their question wording, and pollsthat are taken close to election day (at least in circumstanceslike those of 1984) tend to favor the party currently advantagedin the presidential race. 相似文献

Correspondence to Andy Bilson, Department of Social Work and Social Policy, University of Northumbria, Newcastle NE7 7XA. E-mail Andy_Bilson{at}Unn.AC.UK Summary Research carried out since the implementation of the ChildrenAct 1989 based on a sample of 848 children looked after by localauthorities indicates that previous estimates of the numberswho have no contact with parents may have underestimated theextent of the problem, and that despite the emphasis placedon contact by the Children Act there is still much work to bedone to improve practice. The research not only confirms earlierfindings about the instability of placements in care but alsoshows differences in face to face contact which depend on thelength of time in care or accommodation and the reason for entry,as well as differences between children placed in residentialand foster care. Finally it was found that where children havespent long periods in care they tend to have little contactwith fieldworkers, and it is suggested that there is a needto redefine the social work agenda for this vulnerable groupof children. 相似文献

The "positivity bias" is a term used to describe the consistentfavorable evaluation of public figures found in surveys overthe past 40 years. This paper explored several possible artifactualexplanations for this bias,focusing on the survey instrumentitself. Two experiments varied the labeling and ordering ofscale endpoints, the affective value of the initial contextevaluated, and the presence or absence of a prestigious jobtitle associated with the nameof the public figure. None ofthe variations produced significantly different levels of positivitythan the standard control condition used in each experiment.RichardR.

The basic concepts and application of spectral analysis are explained. Stationary time series and autocorrelation are first defined. Autocorrelation is related to the familiar concepts of variance and covariance. The use of autocorrelation analysis is explained in estimating the interdependent relationship of a time series over discrete time lags. In order to measure the behavior of the time series using autocorrelation, it would be necessary to examine a very large number of autocorrelation lags. Alternatively, the technique of Fourier analysis can be used to transform the autocorrelation function of the time series into a continuous function, termed a spectrum. The spectrum has a one to one correspondence to the autocorrelation for the time series and has the advantage of representing all possible autocorrelations over the discrete time lags. The spectrum can then be examined as a measure of the behavior of the time series. Spectral analysis indicates the reliability of the analysis of autocorrelated variables when familiar statistical techniques such as sample means and variances are used. The application of spectral analysis to management science problems in three general areas is illustrated: (1) inventory demand, (2) transportation simulation, and (3) stock market price behavior. Spectral analysis was used to detect cycles and trends in the data. Analyses were focused on the spectrum which provides a measure of the relative contribution of cycles in a band of frequencies to the total variance of the data. 相似文献
