Biological sex variation in bone mineral density in the cranium and femur

Objectives

Sex and age trends in bone mineral density (BMD) play an important role in the estimation of age-at-death (AAD) of unidentified human remains. Current methodologies lack the ability to precisely estimate age in older individuals. In this study, BMD of the cranium and femur measured by DXA were examined to establish their applicability for age estimation in older adults. BMD as measured by DXA, is most commonly used clinically for prediction of osteoporotic fracture risk. We hypothesized that weight-bearing and non-weight-bearing bones, the femur and cranium, respectively, would provide valuable insights for aging.

Adult brothers and juvenile uncles: Generations and age differences in families at the end of the Middle Ages

In medieval families, dependent relationships did not fall exclusively within the context of parental ties. For various reasons, children sometimes grew up with a much older brother or sister or with uncles or aunts younger than themselves. The article examines these relationships in the household at the end of Middle Ages using fiscal documents and accounts of miracles. The questions are what sort of relationships existed when age and generation did not coincide, how authority was exercised, how dependent relationships should be analyzed, and how autonomy was acquired. These questions can place avuncular and fraternal relationships in a new and different light.     

Physical stature and biological living standards of girls and young women in the Netherlands,born between 1815 and 1865

This is the first study in Dutch anthropometric historiography that describes and analyzes the development of the biological standard of living of girls and young women from the perspective of female adult stature. It is shown that adult stature of women, imprisoned in the second half of the nineteenth century and born between 1815 and 1865, slightly increased, approximately 1cm. From 1850 onwards stature of women born in the cities notably increased. Development of female adult stature was compared to that of male stature; both were quite similar. No circumstantial evidence was found that girls or young women were on a disadvantage with respect to nutrition and (medical) care.     

Some realities about sprawl and urban decline

Abstract

Many urban analysts believe suburban sprawl has become an important issue because it helps generate two types of problems: growth‐related difficulties like rising traffic congestion, and high concentrations of poor minority households in core‐area neighborhoods. However, a careful regression analysis of measures of both sprawl and urban decline shows no statistically significant relation between these two conditions.

The basic nature of the American urban development process would cause core‐area poverty concentrations even if sprawl were replaced by more compact growth forms. But sprawl does aggravate growth‐related problems. Those problems could be attacked through either alternative overall growth strategies—such as high‐density, tightly bounded growth—or specific anti‐sprawl tactics, such as regional tax‐base sharing and regional coordination of land uses. But no feasible policies are likely either to alleviate traffic congestion much or cause most American regions to abandon sprawl.     

Empty Neighborhoods: Using Constructs to Predict the Probability of Housing Abandonment

Abstract

Enforcement of the law prohibiting housing discrimination depends largely on actions initiated by persons who believe they have been victimized and, presumptively, on their knowledge of their legal rights. It is therefore important to establish what people know about fair housing law. A recent national survey examines this topic and explores whether public knowledge makes any difference.

A majority of the public is aware of and approves of many aspects of fair housing law, although the size of that majority varies depending on which aspect of the law is considered. By contrast, only a minority of the public is aware of and accepts protections provided to renter families with children. There is an association between knowledge of the law, recognition of conduct perceived to contradict it, and willingness to respond to such conduct, suggesting a link between knowledge and likelihood of self‐protective responses, as envisioned by the Fair Housing Act.     

Comment on Donald R. Haurin and Hazel A. Morrow‐Jones's “the impact of Real Estate Market knowledge on tenure choice: A comparison of black and white households”

Abstract

Haurin and Morrow‐Jones analyze a sample of survey respondents from Columbus, OH, and find that additional knowledge about real estate markets increases the likelihood of homeownership. They conclude that differences in real estate knowledge contribute importantly to explaining some of the racial gap in homeownership rates; this finding leads to their conclusion that the racial gap can be addressed through public policy interventions, including financial counseling programs.

Their research broadly addresses three questions: Why does the racial gap in homeownership exist? Why does it persist? What can be done to reduce it? We compare their findings with those of other researchers and conclude that improved financial literacy may well be an important tool for reducing the gap, but that the causes for its existence and persistence are complex and that improving financial literacy alone may not be sufficient to have a significant and lasting impact.     

Comment on Donald R. Haurin and Hazel A. Morrow‐Jones's “rhe impact of Real Estate Market knowledge on tenure choice: A comparison of black and white households”

Abstract

Racial differences in tenure have been large and persistent, with white householders much more likely to own their homes than blacks. Haurin and Morrow‐Jones surveyed a sample of 1,002 in metropolitan Columbus, OH, in 2005 to determine the causes of the tenure gap between blacks and whites.

Social and economic differences played a dominant role, but Haurin and Morrow‐Jones also identified a racial difference in real estate and financial knowledge, a difference they suggest could be reduced or eliminated with education. This comment raises questions about national homeownership goals and points out that Haurin and Morrow‐Jones overlook the consequences of pervasive racial residential segregation and the effects of both past and current discrimination.     

Hacia un modelo de atención a la discapacidad basado en los derechos humanos

The social model of disability is presented as a new paradigm of the recent disability treatment, that has had theoretical and legal current development. It is a model that considers that the origins of disability are not either religious or scientific, but social in a great measure. From this new perspective, it is emphasized that the population with disability can contribute to the society in the same circumstances that the rest of the population, which integrates the society, all this from a valorization of the inclusion perspective and respect of diversity. This model is closely related with certain essential values which underline the human rights, such as human dignity, individual freedom and equality; all these conduce to a decrease of barriers and lead to a social inclusion that sets basis to principles as: personal autonomy, nondiscrimination, universal accessibility, environmental normalization, civil dialogue, inter alia. The premise is that disability is part of a social construction, and it is not the deficiency created by the society itself what limits and prevents people with disability to be included, to decide or to design autonomously their own life plan with opportunity equality.
