Proxies in the New Political Economy: Caveat Emptor 总被引:3,自引:0,他引:3
John R. Hanson II 《Economic inquiry》2003,41(4):639-646
Some common professional criteria for evaluating econometric tests that use proxies for political, social, and institutional variables as regressors may lull scholars into a false sense of security about specious results. The highly publicized correlations between income and economic freedom based on the economic freedom indexes supplied by the Fraser Institute, Heritage Foundation, and Freedom House are used as illustrations. Because these correlations bear strong resemblances to one another, most economists would consider them mutually supportive. Yet this is not so, implying that mutual resemblance and consistency are not criteria for judging econometric results. (JEL B49 , C19 ) 相似文献

This paper examines a model of treatment for working with sibling groups. It is suggested that the sibling group is rarely considered as a viable treatment entity, yet siblings potentially exert a powerful influence within the family system. Assumptions underlying this model of treatment are examined. As a unit of treatment, sibling groups can be worked with in three ways: (1) as an adjunct to family or adult treatment, (2) as an adjunct to individual child therapy, and (3) by itself. Treatment objectives are described and a case illustration is provided. Finally, limitations and benefits of sibling group treatment are discussed. 相似文献

This qualitative study involved in-depth interviews with 11 parents whose children had been taken into custody. The initial reactions and responses of the parents to the detention of their children were examined, as well as these parents' thoughts and feelings about theprocess and their involvement in the juvenile justice system. The following major themes emerged from the data analysis: (a) feeling frustrated and confused, (b) a perception of the system as being fair, (c) the juvenile system assuming a parental role, and (d) the influence of detention on family dynamics. Findings highlight the personal experiences of the parents as they attempted to navigate the juvenile justice system. 相似文献

The Atlanta Sociological Laboratory, 1895-1924, comprised the first American school of sociology (Wright 2002). Despite this fact, the sociological accomplishments of this group of scholars are relatively absent from the existing sociological literature. Data collected for this investigation indicate that the Atlanta Sociological Laboratory has been rendered sociologically invisible because of race prejudice, the perception that the school's findings were ungeneralizable, that their methods of research unsophisticated and of low quality, and that they omitted theory from their analyses. The findings of this investigation indicate that the Atlanta Sociological Laboratory utilized a sophisticated methodology to produce generalizable findings that included theory despite the race prejudice that existed during that period in American history. 相似文献

The history of racism in the United States has produced a paradox in social movement literature: blackness shaped the character and substance of black antiracist mobilization, but whiteness shapes most analysis of their efforts. Despite frequently using the black Civil Rights Movement for theory development and testing, leading theorists have yet to identify a specific theory of race undergirding their analysis or explaining how racism impacts the trajectory of antiracist social movements. Instead, theorists rely on common white-privileging notions of race that hinder analyses of black movements. I critically analyze political process theory (PPT) from a racial perspective, showing that the dominant critiques of PPT stem from PPT creators’ failure to critically theorize race while analyzing the Civil Rights Movement. Theorists implicitly adopted white-centered perspectives that ultimately undermined PPT’s development. I conclude with a call to simultaneously theorize collective action and the system of inequality with which a movement is engaged. 相似文献

Although many different approaches are currently being used to create planned change in organizations, Kilmann and Mitroff feel that too little attention has been paid to determining the effectiveness of these different methods in solving the organizations' problems. Based on intervention theory and the consulting process, the authors offer a method of evaluating an organization's approach to change to determine if it is well-suited to the types of problems being experienced. The process of change is diagrammed as a five-step cycle: 1) sensing problems; 2) defining problems; 3) deriving solutions; 4) implementing solutions; and 5) evaluating outcomes. Most consultants enter the process at step 3 which increases the probability that they will try to solve the wrong problem (termed Type III error). A second source of trouble is that consultants are usually trained in one or two disciplines and, therefore, see problems primarily in those perspectives. Kilmann and Mitroff suggest the use of teams of consultants so the problems can be conceptualized from a number of different viewpoints. 相似文献

Some properties of control procedures with variable sampling intervals (VSI) have been investigated in recent years by Amin, Renolds et al, and others. Such procedures have been shown to be more efficient when compared to the corresponding fixed sampling interval (FSI) charts with respect to the Average Time to Signal (ATS) when the Average Run Length (ARL) values for both types of procedures are held equal. Frequent switching between the different sampling intervals can be a complicating factor in the application of control charts with variable sampling intervals (VSI). This problem is being addressed in this article, and improved switching rules are presented and evaluated for Shewhart, CUSUM, and EWMA control procedures. The proposed rules considerably reduce the average number of switches between the sampling intervals and also improve the ATS properties of the control procedures when compared to the conventional variable sampling interval procedures 相似文献

ABSTRACT This study examines the relationship between various measures of parental and student expectations and aspirations and math achievement among Latino 12th graders of immigrant parents in the Educational Longitudinal Study (ELS): 2002 database. Findings indicate parental expectations and aspirations were not significant predictors of student achievement after controlling for an index of covariates. Moreover, neither were student expectations, agreement between student and parent expectations, nor student perceptions of parental aspirations. The analyses of the secondary questions likewise indicated only one strong relationship between aspirations, expectations, and parents' time in the United States – parental aspirations and expectations. 相似文献
