Fertility and migration in the heart of the industrial revolution.

This study examines demographic growth and change in Tilleur in the valley of Meuse in Belgium during 1807-80 during the process of industrialization and urbanization. The proportion of immigrants (foreigners and Flemings) increased from 15% in 1807 to 65% in 1856. After 1856, population and industrial growth stabilized. During 1856-66 the proportion of natives stabilized, and the proportion of Flemings increased. It is argued that in Tilleur there were two phases: a foundation phase of industrial and population growth and a phase of maturation with decreased non-native population and greater similarity between groups. Immigrants contributed to the birth rate in greater proportions than their proportion in the population of Tilleur. During 1847-66 native population increased annually from 2.4% to 3.8%. Migrants' annual increases were diminished by the effects of mortality but expanded by the influence of in-migration. During 1857-66 the proportion of foreigners declined and marked the transition to a new phase. During 1830-66 the sex ratio grew from 93 to 119. During the Industrial Revolution in Tilleur, women shifted from outnumbering to undernumbering men. The iron and coal in the region attracted men. The sex ratio among the Flemish was 214 in 1866. In 1830 the proportion of fertile women was higher among immigrants and declined thereafter. Age at marriage rose for natives and declined for immigrants. The native population structure by sex, age, and marriage did not favor the birth rate. During 1866-80 the birth rate of foreign immigrants and rural natives declined, the birth rate of natives doubled, and the gap between these two groups narrowed. The changes among immigrants during the foundation phase led to fertility decline in the maturation phase. Marriage and migration interactions linked the industrial revolution with the demographic transition.     

Marriage and power: Age at first marriage and spousal age gap in lesser developed countries

This paper examines age at first marriage for women and spousal age gap as an indicator for female agency from 1950 to 2005. Using a dataset of 77 LDCs this paper seeks to explore which variables determine differences at a country level in marriage patterns. We look at the influence of urbanisation, education, percentage population of Muslim faith, and family type. We find that education is a key in determining at what age women marry, having as would be expected a positive effect on age at first marriage and depressing spousal age gap. Urbanisation is significant, with a positive effect on age and negative on spousal age gap, although the effect is not very large. The percentage Muslim variable depresses female age at first marriage and increases spousal age gap but only when family type is not controlled for. The initially strong negative effect of percentage population Muslim over the period under consideration on age of first marriage has decreased, which raises some interesting questions about the role of Islam in female empowerment.     

The core technique in the determination of age at death of skeletons.

This study proposed an histological method of estimating age at death in skeletons that uses a 0.4-cm-diameter core of cortical bone. Age-estimating regression equations were generated from data obtained from the analysis of bone cores taken from femurs, tibiae, humeri, and ulnas of cadavers. When the regression equations generated in this study were applied to eight forensic science cases, accurate ages at death were estimated.

Assessing the relationship between maternal cigarette smoking during pregnancy and age at first police contact

Several types of pre- and perinatal risk factors, such as maternal cigarette smoking, are related to various manifestations of life-course-persistent criminal offending. Studies have reported evidence of a relationship between maternal prenatal cigarette smoking and antisocial/criminal behavior. All of these studies, however, used white male samles, thus limiting the generalizability of research findings. In an attempt to overcome this problem, we employ data from the Philadelphia portion of the National Collaborative Perinatal Project to examine the possible link between maternal prenatal cigarette smoking and the age at first police contact in a cohort of African-American males and females followed through age 17. Logistic regression analysis indicates that maternal prenatal cigarette smoking has a significant effect on the age at first police contact, even with controls for a variety of other risk factors. Although maternal cigarette smoking significantly predicted early onset among males but not females, odds ratios suggest that the effect is quite similar across genders. Future research directions are addressed.     

The effect of occupational licensing deregulation on migrants in the German skilled crafts sector

Occupational licensing on the national level reduces labor market prospects of individuals with a low likelihood of fulfilling the licensing requirements. Such regulation has the potential to adversely affect the labor market integration of foreign-born citizens and can be an obstacle to the free movement of labor toward its most productive uses. Before the backdrop of increased levels of migration into Germany, and the discussion about harmonizing labor standards in Europe, this paper empirically examines the effects of the deregulation of occupational licensing in the German crafts sector on the proportion of migrants working in this sector. The results suggest that the deregulation has increased the proportion of migrants among self-employed as well as employed craftsmen in the fully deregulated trades.     

我国《婚姻法》中夫妻财产制度的完善

婚姻法是民法的重要组成部分,也关系到千千万万个家庭和每一个人。在经过激烈的争论和探讨后,我国新《婚姻法》终于尘埃落定,并相继出台了两个司法解释,但理论研究和学术讨论并未因此而结束。本文通过对作为婚姻法重要内容的财产关系的若干问题的论述,指出了某些尚值得商榷的地方,并对此提出了一点建议。     

Evaluation of age estimation technique: testing traits of the acetabulum to estimate age at death in adult males

This study evaluates the accuracy and precision of a skeletal age estimation method, using the acetabulum of 100 male ossa coxae from the Grant Collection (GRO) at the University of Toronto, Canada. Age at death was obtained using Bayesian inference and a computational application (IDADE2) that requires a reference population, close in geographic and temporal distribution to the target case, to calibrate age ranges from scores generated by the technique. The inaccuracy of this method is 8 years. The direction of bias indicates the acetabulum technique tends to underestimate age. The categories 46-65 and 76-90 years exhibit the smallest inaccuracy (0.2), suggesting that this method may be appropriate for individuals over 40 years. Eighty-three percent of age estimates were ±12 years of known age; 79% were ±10 years of known age; and 62% were ±5 years of known age. Identifying a suitable reference population is the most significant limitation of this technique for forensic applications.     

婚姻家庭立法理念的审思

1950年《婚姻法》曾经是新中国成立后颁布的第一部法律。其立法理念不仅在现行《婚姻法》中得到继承和发展,而且在现行《婚姻法》修正草案中也得到发扬与延伸。探寻婚姻家庭立法理念的继承性、扬弃性、时代性,既是理解婚姻家庭领域诸制度发展变化规律的需要,也是掌握婚姻家庭立法技术的需要,并将为婚姻家庭制度的完善提供切实可行的立法建议。     

重构婚姻判断标准的理论价值和实践意义

中国尚未建立科学的婚姻判断标准体系，判断婚姻的主要标准，就是单一的婚姻效力判断标准。不论是什麽形态的婚姻，都用婚姻有效无效标准判断。这种婚姻判断标准，不能满足理论与实践的需要，容易造成对不同婚姻形态的误判。因此，应当建立以婚姻的属性要件、形成要件和效力要件为评判标准的科学评判体系。

Using the acetabulum to estimate age at death of adult males

The acetabular region is often present and adequately preserved in adult human skeletal remains. Close morphological examination of the 242 left male os coxae from the identified collection of Coimbra (Portugal) has enabled the recognition of seven variables that can be used to estimate age at death. This paper describes these variables and argues their appropriateness by analyzing the correlation between these criteria and the age, the intra- and interobserver consistence, and the accuracy in age prediction using Bayesian inference to estimate age of identified specimens. Results show significant close correlation between the acetabular criteria and age, nonsignificant differences in intra- and interobserver test, and 89% accuracy in Bayes prediction. Obtained estimated age of the specimens had similar accuracy in all ages. These results indicate that these seven variables, based on the acetabular area, are potentially useful to estimate age at death for adult specimens.     

The effect of social status on women's age at first childbirth in the late seventeenth- to early eighteenth-century Korea

While records on historical population are available and do exist, the fact that they are so limited in nature is a critical problem. We applied the method of family reconstitution to a Korean household register to deal with these limitations. Based on family reconstitution from five successive registers, we calculated women's age at first childbirth for each social status in two ways: “observed woman's age” at first childbirth = woman's current age–age of her first child, and “estimated woman's age” at first childbirth, which uses linear regression analysis on the basis of positive association between women's age and the age of their firstborn. Our results shed light on the effects of social status and cultural factors on the age at which women in pre-industrial Korea bore their first child.     

The age at death assessment in a multi-ethnic sample of pelvic bones using nature-inspired data mining methods

Recently published studies showed that age assessment methods are population specific. Authors analyse the senescence changes in pubic symphysis and sacro-pelvic surface of a pelvic bone using data mining methods. The multi-ethnic data set consists of 956 adult individuals ranging from 19 to 100 years of age derived from 9 different populations with known age and sex. The results show that accurate and reliable age assessment is possible to three age classes (less than 30, 30-60, 60 and more). The study confirms that population specificity of the methods exists and the variable "sex" is not important in age classification.
