This article suggests that feminist theoretical turns are illuminating to study, as they make explicit how Western feminist theory is interested not only in the content of different theoretical turns, but also, relatedly, in how these turns move feminist theory in particular directions. Exploring some of the current and historical debates about turns in feminist theory, I pay particular attention to how they might be understood in terms of a wide range of work on the non-linear temporalities of feminist theory. I suggest that one way to understand the non-linear temporalities evident in debates over feminist theoretical turns is through a ‘turn to the surface’. To explicate this suggestion, I offer a series of five indicative issues, terms and ideas, which emerge both from recent work on the surface and feminist theory, and from my attempts to think conceptually about turns, surfaces and the relations between them. These are: (i) reflexivity, (ii) possibility, (iii) lines, (iv) knots, and (v) diagrams. I conclude by raising a number of further points that emerge through an attempt to engage in the surfacing of feminist theory.  相似文献

In this paper, we consider several features of teacher‐retention policies based on value‐added measures of effectiveness under a variety of empirically grounded rules and parameters. We consider the effects of policy design by varying the standard above which satisfactory teachers are expected to perform. We simulate recently adopted policies that remove teachers based on consecutive unsatisfactory performance and compare these to policies that remove teachers based on poor performance on average over a multiyear period. We also consider the precision of the performance measure and the underlying variation in teacher quality on policy effects. Finally, the simulation makes a step forward by incorporating recent empirical findings of a relationship between teacher quality and natural attrition from the profession. Our results indicate that deselection policies based on value‐added measures have the potential to improve teacher quality, although understanding the role of policy design, self‐selected exits, and the underlying variation in teacher quality is essential for determining policy effects.  相似文献

Using data from the National Longitudinal Study of Adolescent Health, various demographic, psychological, educational, and family variables were explored as predictors of pregnancy resolution. Only 2 of the 17 variables examined were significantly associated with pregnancy resolution (risk-taking and the desire to leave home). After controlling for these variables, adolescents who aborted an unwanted pregnancy were more inclined than adolescents who delivered to seek psychological counseling and they reported more frequent problems sleeping and more frequent marijuana use. No significant differences were observed for cigarette smoking, frequency of alcohol use, and problems with parents based on alcohol use after the controls were instituted; however without controls, significant associations were observed, underscoring the importance of the use of psychological and situational controls in studies of the consequences of abortion. The information derived from this study is potentially useful to parents and professionals who provide guidance to adolescents regarding pregnancy resolution.  相似文献

The progressivity and equity of both state and federal individual income taxes, as well as the combined system of both taxes, are examined before and after the federal Tax Reform Act of 1986 using a variety of measures applied to federal Statistics of Income individual income tax data; state taxes are calculated using TAXSIM. Our findings are as follows: First, in both 1985 and 1987, state personal income taxes were generally less progressive and more horizontally equitable than the federal system. Second, in moving from 1985 to 1987, state personal income tax systems generally displayed decreased progressivity and horizontal inequity. The combination of the two systems displayed generally lower progressivity and horizontal equity scores when we compare 1987 to 1985. Last, the after-tax income distribution became more unequal when we compared 1987 to 1985.  相似文献
