A Place to Call Home: Cultural Understandings of Heir Property among Rural African Americans*

Abstract Heir property is land held communally by family members of a landowner who has died intestate. Because this informal arrangement does not fit neatly into the individualist‐centered, integrated property rights system of the United States, it is viewed by most as a hindrance to economic development and capitalism. We present an alternative framework for analyzing the significance of heir property in the African American community and its constraints. While the consequences of owning land with clouded title are clear‐ineligibility for housing programs, inability to secure a mortgage or sell timber, and vulnerability to land loss through partition and tax sales‐we argue that a culturally‐based understanding of heir property provides insight to why it persists among rural African Americans. Based on personal interviews with heir property owners, lawyers, housing counselors, and county officials, the authors illustrate how heir property is supportive of certain cultural values and meets the needs of a subset of rural populations in ways that other forms of property ownership cannot.     

The Influence of Family Structure on Sexual Activity in a Randomized Effectiveness Trial for Minority Youth

This study examined the influence of family structure on the outcomes of a sex education program in Miami, Florida. Using an experimental design, data collection occurred at pretest, 3-month, and 6-month follow-up with a sample of teenagers from high schools with a large majority of minority youth, assigned into treatment (n = 549) and control (n = 424) groups. Results indicated family structure had no influence on predicting teen sexual activity at pretest or at 3- or 6-month follow-up. Additional research using experimental designs is needed to assess the influence of family structure on other areas of adolescent development.     

The design of lower‐limb sports prostheses: fair inclusion in disability sport

Within lower‐limb disability running, the design of the prosthesis has shifted from being a tool for restoring function to one of enabling athletes to perform to near non‐disabled standards. This paper examines the background to this development. The authors argue that the impact of technology on the design of prostheses is likely to affect athletes’ abilities and unfairly advantage those who are able to access the most recent innovations. It is shown that historically in the case of lower‐limb sports prostheses, some variation in their performance is evident. The sports legislation does not allow for this difference. It is indicated that these observations are of concern to the sports stakeholders and therefore warrants further attention. It is suggested that the full understanding of the prostheses contribution may never be known. The authors propose a synthesis of quantitative performance data and a qualitatively obtained code of values to help police these concerns.     

Do family caps reduce out-of-wedlock births? Evidence from Arkansas, Georgia, Indiana, New Jersey and Virginia

During the 1990s, 23 states implemented family cap policies as a means to reduce the incidence of out-of-wedlock births among welfare recipients. Using Current Population Survey data from 1989 to 1999, we examine the impact of family cap policies on the birth rates of single, less-educated women with children. We use the first five states that were granted waivers from the Department of Health and Human Services to implement family caps as “natural experiments.” Specifically, we compare trends in out-of-wedlock birth rates in Arkansas, Georgia, Indiana, New Jersey and Virginia to trends in states that did not implement family caps or any other waivers prior to the Personal Responsibility and Work Opportunity Reconciliation Act. We employ several techniques to increase the credibility of results from our “natural experiment,” such as the inclusion of multiple comparison groups, controls for differential time trends, and “difference-in-difference-in-differences” estimators. Our regression estimates generally do not provide evidence that family cap policies reduce the incidence of out-of-wedlock births among single, less-educated women with children.     

Comparison of point estimators of normal percentiles

There are available several point estimators of the percentiles of a normal distribution with both mean and variance unknown. Consequently, it would seem appropriate to make a comparison among the estimators through some “closeness to the true value” criteria. Along these lines, the concept of Pitman-closeness efficiency is introduced. Essentially, when comparing two estimators, the Pit-man-closeness efficiency gives the “odds” in favor of one of the estimators being closer to the true value than is the other in a given situation. Through the use of Pitman-closeness efficiency, this paper compares (a) the maximum likelihood estimator, (b) the minimum variance unbiased estimator, (c) the best invariant estimator, and (d) the median unbiased estimator within a class of estimators which includes (a), (b), and (c). Mean squared efficiency is also discussed.
