By examining the history of the random experiment in the Home Office in the United Kingdom, this article demonstrates that research is not an altogether rational process and that fashion, personality, and politics are at least as important as science and evidence when setting research and policy programs and determining methodologies. The article also shows that even in 1970, the research world was a village and that issues and fashions on one side of it could determine the outcome of decisions on the other side, even though they had no direct relevance. On a more optimistic note, the article shows how the fashions go in cycles so that if you could not get the research funded in the last cycle, just wait 20 years for the cycle to come around and try again. 相似文献

This paper numerically examines the size robustness of various conditional moment tests in misspecified tobit and probit models. The misspecifications considered include the incorrect exclusion of regressors, ignored heteroskedasticity and false distributional assumptions. An important feature of the experimental design is that it is based on an existing empirical study and is more realistic than many simulation studies. The tests are seen to have mixed performance depending on both the original null hypothesis being tested and type of misspecification encountered. 相似文献

This study investigated the associations among psychologically controlling parenting, relational aggression, friendship quality, and loneliness during adolescence. A model was proposed in which relational aggression plays an intervening role in the relations between both parental psychological control and friendship outcomes. In a sample comprised of middle adolescents and their parents, process analyses revealed that psychological control (indexed by parent and adolescent reports) positively predicted adolescents' self-reported relational aggression that, in turn, negatively predicted friendship quality and positively predicted loneliness. The model held for both mothers and fathers and was not moderated by adolescent gender. The discussion focuses on possible mechanisms explaining the relations among psychological control, relational aggression, and friendship outcomes. 相似文献

We examine methods for reducing respondent burden in evaluating alter–alter ties on a set of network structural measures. The data consist of two sets, each containing 45 alters from respondent free lists: the first contains 447 personal networks, and the second 554. Respondents evaluated the communication between 990 alter pairs. The methods were (1) dropping alters from the end of the free-list, (2) randomly dropping alters, (3) randomly dropping links, and (4) predicting ties based on transitivity. For some measures network structure is captured with samples of less than 20 alters; other measures are less consistent. Researchers should be aware of the need to sample a minimum number of alters to capture structural variation. 相似文献

The approach to normality of an estimate is displayed graphically by the nonlinearity in the derivative of the log density, and this nonlinearity is related to the accuracy of the normal approximation for the tail area. Using techniques from small-sample asymptotics, an alternate proof of the central limit theorem is given and same indices of tail behavior are examined. 相似文献

Religion and social control have been a sociological concern since Durkheim and Weber, and the relationship between religion and punishment has long been the subject of speculation. However, surprisingly little empirical research exists on the role of religion or religious context in criminal justice, and almost no research on the role of religious context on actual sentencing practices. We conceptualize the potential relationships between religious context and sentencing severity by drawing from the focal concerns and court community perspectives in the sentencing literature and from the moral communities theory developed by Rodney Stark. We suspect that Christian moral communities might shape notions of perceived blameworthiness for court community actors. Such moral communities might also affect notions of community protection—affecting perceptions of dangerousness, or perhaps rehabilitation, and might influence practical constraints/consequences (e.g., local political ramifications of harsh or lenient sentences). We examine these questions with a set of hierarchical models using sentencing data from Pennsylvania county courts and data on the religious composition of Pennsylvania counties from the Associated Religion Data Archives. We find that county Christian religious homogeneity increases the likelihood of incarceration. In addition, Christian homogeneity, as well as the prevalence of civically engaged denominations in a county condition the effects of important legally relevant determinants of incarceration. Furthermore, we find evidence that Christian homogeneity activates the effect of local Republican electoral dominance on incarceration. We argue that Christian homogeneity affects sentencing practices primarily through local political processes that shape the election of judges and prosecutors. 相似文献

Setting the Scene This is the story of research identified by powerful institutional players and a non-disabled researcher as being ethical and non-discriminatory, but held by research subjects with disability to be disrespectful, discriminatory and unethical. It shows the imbalance of power, and limitations of existing Australian provisions in the regulation of research, privacy and anti-discrimination. It also attests to the discursive shaping of notions of justice and ethics by institutional players to suit institutional and corporate ends. This is a true story where only the names of all players have been changed. The author has received consent from the Australian organisation of people with disability to publish this, as they are concerned to articulate some of the issues. Hence, the names are changed, but all other details of this saga remain the same. The account begins in September 1994 and concludes in February 1996. Our assembled cast is a researcher, the State Department of Sport and Recreation, the University of Noname and the organisation 'Humans with Disabilities Inc.' (HWD). 相似文献
