Child mortality was analyzed in relation to 3 dimensions of reproductive behavior: birth intervals, additional children desired, and contraceptive use. Study data were drawn from a 1978 survey conducted in 2 predominantly rural governorates, Beheira and Kafr El-Sheikh, in lower Egypt. Within each governorate, 2 districts were selected on the basis of their distance from the capital of the governorate, agricultural output by major crops, percent of the population urban, infant mortality rate, and crude birthrate. Within each of the 4 districts, villages were randomly drawn from 3 strata: villages lacking any governmental services; villages with limited services (health center or primary school); and villages served by a combined unit center providing integrated services. A random sample of household heads was selected from household registration records of the provision office of each district. 1200 interviews were obtained from 685 households. Restriction of the sample to women with 1 or more live births, and the elimination of 13 cases with incomplete or inaccurate information, yielded 1010 cases for analysis. The basic measure of actual fertility was birth intervals. For the total sample and within each age category, cumulative fertility is higher the greater the number of child deaths. The data demonstrate a strong relationship between child mortality experience and cumulative fertility. The problem lies in interpreting such results. With some exceptions, birth intervals increased as expected with increasing parity. Women without child death experience displayed longer birth intervals than women who had not lost a child. With the single exception of the 7th parity women, all differences were statistically significant. The data fail to eliminate potential biological influences on subsequent fertility. With biological influences adequately controlled, no behavioral differences remained. Women who experienced child mortality desired greater numbers of additional children than women without child death experience. 19% of respondents were ever users of contraception, with women of low parity the least likely ever to have used contraception.  相似文献

Presidents traditionally have had great success when nominating justices to the Supreme Court, with confirmation being the norm and rejection being the rare exception. While the confirmation process usually ends with the nominee taking a seat on the Court, however, there is a great deal of variance in the amount of time it takes the Senate to act. To derive a theoretical explanation of this underlying dynamic in the confirmation process, we draw on a spatial model of presidential nominations to the Court. We then employ a hazard model to test this explanation, using data on all Supreme Court nominations and confirmations since the end of the Civil War. Our primary finding is that the duration of the confirmation process increases as the ideological distance between the president and the Senate increases. We also find evidence that suggests that the duration increases for critical nominees and chief justices and decreases for older nominees, current and previous senators, and nominees with prior experience on state and federal district courts .  相似文献

The construction of public problems has a lasting influence on implementation in a given policy subsystem. National and sociopolitical contexts influence issue definition differently across nations. However, the degree to which nation-specific issue definition takes place has been insufficiently explored. In recent years, the growing incidence of autism has led to a quest for causal factors. One hypothesis posits that the use of mercury in vaccines may be a culprit. This paper examines the definition of the mercury and autism issue in Australia, Canada, the United Kingdom, and the United States. Insights into the comparative elements of issue definition are suggested by the case. These insights are of particular importance to administrators, as agencies are deeply involved as objects and actors in the process of issue definition and are often responsible for implementing new and redefined policies.  相似文献

The role of interpersonal sensitivity in the relation between romantic stress and depression was examined in 55 adolescent girls from an inner-city high school. Depression, interpersonal sensitivity, and chronic and episodic romantic stress were measured at two time points, 6 months apart. Interpersonal sensitivity was found to moderate the longitudinal relation between romantic stress (both chronic and episodic) and depression. In contrast, interpersonal sensitivity did not potentiate depressive responses to non-romantic interpersonal stress, suggesting particular importance of stress in the romantic domain for adolescent girls. Results indicate that girls' sensitivities to romantic relationship stress should be specifically addressed in depression prevention and intervention programs.Received her PhD from the University of Southern California. Research interests include the influence of romantic relationship factors, such as romantic stress and dating violence, on the development of depression during adolescence.Received her PhD from the University of California, Los Angeles. Research interests include the interplay between adolescent depression, personality disorder symptoms, and interpersonal variables including adjustment in friendships and romantic relationships.Research interests include cognitive and interpersonal factors in adolescent depression.  相似文献
