William E. Skidmore II 《Slavery & abolition》2018,39(1):147-168
This article examines how American abolitionists educated themselves about Brazilian slavery and race relations. Beginning with the Iberian–American Revolutions and ending with James Redpath’s 1867 influential exposé on Brazil, this article explores how American abolitionists viewed Brazil and how their understandings about Brazilian slavery and race relations changed over the course of the nineteenth century. These changes were not a progressive march by abolitionists toward a deeper and better understanding of Brazil but, instead, reflect how antislavery writers emphasized various aspects of Brazilian slavery and culture at different periods in order to further their own ideological and political agendas. At the same time, these agendas led abolitionists to pioneer some of the earliest methods for the comparative study of slavery on a global scale. 相似文献

Information systems that are to support strategic planning must be developed on bases that reflect the unique nature of strategic organizational decisions. This paper presents a systems design methodology which implements five basic criteria for the design of a strategic planning Management Information System (MIS). The methodology uses discriminant analyses of the perceived importance to managers of various categories of strategic information to delineate the most significant information requirements of various managerial groups. These results are augmented with similar analyses based on the personal characteristics of the potential system users in order to implement a design criterion related to the integrated nature of a planning MIS and a ‘teaching’ objective which is posited to be valid and feasible for such a system. 相似文献

Usual fitting methods for the nested error linear regression model are known to be very sensitive to the effect of even a single outlier. Robust approaches for the unbalanced nested error model with proved robustness and efficiency properties, such as M-estimators, are typically obtained through iterative algorithms. These algorithms are often computationally intensive and require robust estimates of the same parameters to start the algorithms, but so far no robust starting values have been proposed for this model. This paper proposes computationally fast robust estimators for the variance components under an unbalanced nested error model, based on a simple robustification of the fitting-of-constants method or Henderson method III. These estimators can be used as starting values for other iterative methods. Our simulations show that they are highly robust to various types of contamination of different magnitude. 相似文献

Glenn W. Suter II Barney W. Cornaby Charles T. Hadden Ruth N. Hull Mark Stack Fred A. Zafran 《Risk analysis》1995,15(2):221-231
Human health and ecological risks must be balanced at hazardous waste sites in order to ensure that remedial actions prevent unacceptable risks of either type. Actions that are designed to protect humans may fail to protect nonhuman populations and ecosystems or may damage ecosystems. However, there is no common scale of health and ecological risk that would allow comparisons to be performed. This paper presents an approach to addressing this problem based on classifying all risks (i.e., health and ecological risks due contaminants and remediation) as insignificant ( de minimis ), highly significant ( de manifestis ), or intermediate. For health risks the classification is based on standard criteria. However, in the absence of national guidance concerning the acceptability of ecological risks, new ecological criteria are proposed based on an analysis of regulatory precedents. Matrices and flow charts are presented to guide the use of these risk categories in remedial decision making. The assessment of mercury contamination of the East Fork Poplar Creek is presented as an example of the implementation of the approach. 相似文献

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 paper analyses the sustainability of family bargaining agreements by developing a non-cooperative game between two spouses
with symmetric preferences. To that end, we develop, by using a general utility function, a repeated non-cooperative game
involving two players with symmetric preferences, where the characterization of a Nash sub-game perfect equilibrium allows
us to demonstrate that the spouse with the greater bargaining power has a greater incentive to reach an agreement. This result
is also reproduced by using a particular example of linear preferences in consumption. However, the influence of the bargaining
power on the sustainability of a bargaining solution depends on the specification of the individual preferences, as well as
the degree of altruism between the spouses.
