Abstract 1.1. The course of Spanish population growth from the end of the 16th to the beginning of the 18th century was set by the effects of what demographers call 'catastrophic' mortality. As in most European populations, the occasional but recurrent ravages of epidemics, especially plague, wiped out the excess of births over deaths accumulated in 'normal' years. How accurate and close to reality this statement is cannot be discussed here; but we shall assume that, until the rSth century, short-term growth was offset by mortality above the normal levels caused by epidemics. 相似文献

Abstract 3.1. A regional approach often reveals features of population trends not evident in national data. We have already pointed out that the 1768 census followed the ecclesiastical sub-divisions of the country; therefore its territorial data are not comparable with those derived from later enumerations. The 1787 and 1797 censuses, on the other hand, were based on civil sub-divisions, which can be compared, when aggregated, with later censuses of the modern statistical era. 相似文献

Major league baseball career length in the 20th century 总被引:1,自引:0,他引:1
The sport of baseball has used statistics to enhance understanding for fans for over a century, yet there is limited data
on player careers. This study fills that void by examining the careers of baseball players over the last century. Between
1902 and 1993, 5,989 position players started their careers and played 33,272 person years of major league baseball. A rookie
position player can expect to play 5.6 years; one in five position players will have only a single-year career, and at every
point of a player’s career, the chance of exiting is at least 11%. Position players who start younger and begin their careers
in more recent decades all have longer and more stable careers; nevertheless, baseball careers are not compressed versions
of normal careers, but are substantially skewed toward early exit.

We investigate the extent and implications of cohabitation and marriage among U.S. welfare recipients. An analysis of four data sets (the Current Population Survey, the National Survey of Families and Households, the Panel Study of Income Dynamics, and the National Longitudinal Survey of Youth) shows significant numbers of cohabitors among recipients of AFDC. An even more surprising finding is the large number of married women on welfare. We also report the results of a telephone survey of state AFDC agencies conducted to determine state rules governing cohabitation and marriage. The survey results indicate that, in a number of respects, AFDC rules encourage cohabitation. Finally, we conduct an analysis of the impact of AFDC rules on cohabitation, marriage, and single motherhood and find weak evidence in support of incentives to cohabit. 相似文献

Various styles of "male love" occurring in the 19th century are introduced. Locations and public ordinances relating to these styles of love are discussed. The development of the homosexual role is broached along with the question of whether attitudes and laws of the 19th century were responsible in part for the development of normative expectations for homosexuality which might in turn have repressed its growth. 相似文献

Educational stratification by ethnicity in China: Enrollment and attainment in the early reform years 总被引:1,自引:0,他引:1
Hannum E 《Demography》2002,39(1):95-117
Using evidence about educational disparities, this article demonstrates the need for attention to minority populations in studies of social stratification in China. Analyses of data from a 1992 survey of children demonstrate substantial ethnic differences in enrollment among rural 7- to 14 year olds, with rates for ethnic Chinese boys roughly double those for girls from certain ethnic groups. Multivariate analyses indicate that the ethnic gap can be attributed, in part, to compositional differences in geographic location of residence and socioeconomic background. There is no general tendency of a greater gender gap for minorities than for the ethnic Chinese, but significant differences in the gender gap emerge across individual ethnic groups. Together with evidence from census data showing that ethnic disparities in junior high school transitions increased between 1982 and 1990, these results stress the continuing significance of ethnicity as a fundamental factor that conditions status attainment opportunities in China. 相似文献

Abstract In demographic literature Java occupies a special position. It is the island where in the nineteenth century a 'population explosion' occurred. In other developing countries this took place in the twentieth century. Following the official figures Java had a population size of about 4.5 million in 1815 (Raffles's Census) and 28.5 million in 1900. The result is an extraordinary rate of growth of 2.2% per year. In this paper it is argued that it is impossible to correct the data by adjusting them. A more promising method is to study the factors which are responsible for the demographic situation, i.e. economic conditions, the so-called pax neerlandica and the health situation in the period 1800-1850. This period has been specially studied, because it is crucial for the calculation of population size which is normally based on the 1815 period. It is suggested that Java cannot really claim to be an exceptional case in the period 1800-1850. This means that the growth rate - in line with the estimates of Carr Saunders and Sauvy -has to be estimated (greater accuracy is not possible) as between 0.5% and 1.0); per annum. On the basis of estimates and calculations, the population size of Java may have been somewhere between 8 and 10 millions around 1800, the latter estimate being the more realistic figure. The view that there was exceptionally rapid population growth in Java in the nineteenth century is to an important degree the product of a Europe-centred approach to the history of Java. 相似文献

Although a large body of research examines the impact of welfare reform, there remains considerable uncertainty as to whether single mothers’ well-being improved in the wake of these policy changes. Using unique data from the DDB Worldwide Communications Life StyleTM survey, this paper exploits a large battery of survey questions on self-reported life satisfaction and physical and mental health to study the impact of welfare reform on the subjective well-being of single mothers. The identification strategy relies on a difference-in-differences framework to estimate intent-to-treat effects for the welfare waiver and TANF periods. Results indicate that the bundle of TANF reforms had mostly positive effects on single mothers’ subjective well-being. These women experienced an increase in life satisfaction, greater optimism about the future, and more financial satisfaction. Furthermore, these improvements did not come at a cost of reducing mental and physical health. Welfare waivers, in contrast, had largely neutral effects on well-being. I provide indirect evidence that the increase in single mothers’ employment after welfare reform can plausibly explain the gains in subjective well-being. 相似文献

This qualitative study examines relationships between adult daughters caring for elderly disabled mothers and the mothers' personal care workers (PCWs) paid directly by the Wisconsin Community Options Program (COP). A subset of a larger study, in these five cases PCWs provide substantial hands on care without substituting for the heavy care also provided by the daughters. Direct payment offers the daughters and workers freedom to schedule around their family obligations and other limits and tailor care to the abilities of all three participants. It also allows the daughter to be the paid provider when she chooses. Expansion of such supportive services could benefit many more low and middle income families. 相似文献

The determinants and consequences of child care subsidies for single mothers in the USA 总被引:3,自引:2,他引:1
This paper provides an analysis of child care subsidies under welfare reform in the USA. We used data from the 1999 National
Survey of America's Families to analyze the determinants of receipt of a child care subsidy and the effects of subsidy receipt
on employment, school attendance, unemployment, and welfare participation. Ordinary least-squares estimates that treat subsidy
receipt as exogenous show an effect of subsidy receipt on employment of about 13 percentage points. Two-stage least-squares
estimates that treat subsidy receipt as endogenous and use county dummies as identifying instruments show an effect of 33
percentage points on employment, 20 percentage points on unemployment, and no effects on schooling and welfare receipt.

Ideas on man-boy friendships prevailing in early 20th century Germany are analyzed in this paper. The friendships based on the concept of pedagogical Eros, as propagated by Gustav Wyneken (1875-1964) in his Wickersdorf Free School Community, are presented as an example. Wyneken's conviction in 1921 for acts of vice with minors and the diverse reactions in the homosexual and youth movements and the popular press shed light on the viewpoints then held regarding these friendships. As a result of this confrontation, the Platonic model was superseded by the medico-sexological model which has continued to dominate thought on man-boy friendships up to the present day. 相似文献

Inside stories: Maternal representations of first time mothers from pre-pregnancy to early pregnancy
Julia Hopkins David Clarke Wendy Cross 《Women and birth : journal of the Australian College of Midwives》2014,27(1):26-30
BackgroundAccording to the psychoanalytical literature, it is during pregnancy that maternal representations of the mother–infant relationship become activated. Midwives who are engaged with the mother and the baby have not drawn upon this concept in their practice. In order for this to happen, it is important to understand better the nature of maternal representations and when they are activated from empirical studies.QuestionThe research question is: what are the maternal representations of a group of first time mothers from pre-pregnancy, early pregnancy and to the first ultrasound.MethodA narrative approach was used to gain insight into the maternal representations of first time pregnant womens’ account of their representations. The analysis method was based on thematic approach.ParticipantsFifteen women aged between 23 and 38 years.SettingA midwives clinic attached to a tertiary hospital in Melbourne, Australia.FindingsFirst-time pregnant women's maternal representations were activated when a woman begins to plan her pregnancy (‘the time is right’), again at the onset of physical changes to her body as a result of conception (‘my body is changing’), and at the first early ultrasound at around twelve weeks (‘it’ is a real baby).ConclusionMaternal representations are important for the midwife and pregnant women because this concept provides another understanding in relation to the psychological dimension of pregnancy. 相似文献

Infant mortality and fertility in three Bavarian villages: An analysis of family histories from the 19th century 总被引:1,自引:0,他引:1
Knodel J 《Population studies》1968,22(3):297-318
Abstract Family history data derived from the records of three parishes in Bavaria provide evidence for several important demographic questions when analysed in conjunction with information concerning the prevalent breast-feeding practices. The results suggest strongly that breast feeding can prolong birth intervals substantially. The evidence concerning the independent influence of infant deaths on subsequent birth intervals is inconclusive. It is clear, however, that even if such an influence did exist it was relatively small, compared to the effect of lactation. In addition the results do not lend support to the hypothesis that couples experiencing low child mortality practised family limitation more than couples experiencing high child mortality. In all three parishes, however, fertility appeared to influence infant mortality. Infants born after short intervals were subject to considerably higher mortality risks than infants following longer intervals. 相似文献

This paper uses the 1910 Census Public Use Sample to examine how the presence and activities of key family members shaped the labor force activity, domestic work, and schooling of working-age daughters. There is no evidence that daughters worked to send their brothers to school; parents practiced a more egalitarian distribution of resources than the literature suggests. Having brothers and sisters in school increased a daughter’s odds of attending school herself. Similarly, daughters with employed siblings were more likely to be gainfully employed. Nonetheless, parents allocated activities to sons and daughters in ways that reinforced traditional gender roles. Working brothers increase daughters’ likelihood of working in the home, while reducing their odds of attending school. 相似文献

Education influences aspects of demographic behaviour and outcomes including a child sex preference. Sex preferences of children have been studied in different societies because of its associated social and demographic implications. Using the 2014 Ghana Demographic and Health Survey, we examined the association between educational attainment and sex preferences of children. Findings from the study indicated that there is preference for sons (26.1%) compared to daughters (17.4%). At higher levels of education, there is a higher likelihood for no preference for a sex of a child. Among the characteristics of respondents that influenced sex preferences are: gender, lineage, religion, occupation and desired family size. Acquisition of knowledge through education to some extent alter fertility preferences and hence the need to motivate individuals to attain some level of education. 相似文献
