Changes in the relative status of central cities compared to their suburban rings are investigated for the periods 1920 to 1950, and 1950 to 1970. Longitudinal alterations in the relative statuses of the two components across metropolitan areas have primarily involved the suburban ring. Somewhat different processes of change were evident in the two time periods, particularly when metropolitan areas are distinguished by their age. In the 1920 to 1950 period, the oldest metropolitan areas evolved toward higher suburban than central city status, while newer metropolitan areas evolved toward higher central city than suburban status. In the 1950 to 1970 period, metropolitan areas generally moved toward a pattern of higher suburban than central city status, regardless of their individual characteristics such as age or period of development. 相似文献

This paper examines Federal Reserve Board policies that are premised on a negative short-run association of interest rate movements and the rate of inflation. In particular, econometric evidence is provided, supporting the view that tighter monetary policy appears to raise inflation rates in the short run. Conversely, it is demonstrated that easier monetary policy does not necessarily raise inflation rates in the short run. In the case of uncoordinated monetary restrictiveness, interest rate competition among major countries can produce higher inflation and lower growth than was originally intended. 相似文献

The interaction between leaders and members in a year-long family therapy seminar is systematically compared to the process that unfolds between therapist and family during the course of family therapy. A five stage developmental process common to both is postulated and described: (1) Battle for Structure, (2) Naive Enthusiasm, (3) Conflictual Frustration, (4) Task Orientation, and (5) Mutuality. The dynamic elements of each stage are analyzed and factors affecting their development are identified. It is concluded that this five stage process occurs in all similar groups, but that the content of each stage may vary widely from group to group. 相似文献

This paper considers a regression model in which coefficients obtained from a previous regression are themselves the object of analysis. It is shown that the parameters of interest can be obtained in two ways: pooling across observations and subsamples, or a two-stage process of first estimating the coefficients within each subsample, and then using these coefficients as dependent variables in a second stage regression. The relative properties of these estimators are analyzed, and the conditions under which the two estimators are equivalent are derived. 相似文献

This paper presents a general method for testing if a particular type of interaction is present in latin square models with one observation per cell. Computing instructions are given along with a detailed numerical example. A data analysis approach is explained where an experimenter can use various models to determine whether interaction is present. If there is interaction, then a procedure is given for examining a number of models to decide what factors (row, column, treatment) are interacting. In addition, a number of sets of latin square data from the literature are reanalysed to determine if they contain interaction. 相似文献
