Women’s Timing of Receipt of Social Security Retirement Benefits

The 2000–2006 waves of Health and Retirement Study data were used to estimate the effects of human capital characteristics and income sources on women’s timing of receipt of Social Security retirement benefits. Using logistic regression, the likelihood of early election of benefits was increased by earnings regardless of marital status; and, for married women, by husband’s age being greater than wife’s, and by other income. For married women, education decreased the likelihood of electing early benefits. For unmarried women, IRA/annuity income reduced the likelihood of early receipt of benefits. Using multinomial logistic regression, the likelihood of combinations of expected and actual benefit receipt options were estimated. A greater percentage of married, compared to unmarried, women expected and elected early benefits.     

The public relations paradox of erasure: Damnatio memoriae as public relations strategy and tactic

Public relations scholars study how organizations co-create meaning with engaged stakeholders. Not well understood is how and why such co-creation modifies shared meaning, amplifies change, and even “erases” some piece of memory from the public record with the purpose of redirecting and redefining societal narratives. To help establish erasure as a concept for studying public relations, we draw from Freud’s theory of memory to establish a foundation upon which to critique strategic erasure. We adapt Freud’s theory of memory into the intersecting critique of visual rhetoric as public relations by analyzing, via narrative inquiry, remnants of Imperial Rome that have been modified, amplified, but even erased to present Rome’s modern identity. For centuries, even during Imperial Rome, leaders practiced damnatio memoriae —a modern Latin phrase that means “condemnation of memory.” We use this concept to interrogate the public relations identity process Rome’s leaders have used to modify for emphasis and even obliterate Roman elites’ names and images from the texts of public records by destroying, mutilating and modifying statues and monuments as a means for co-creating new public memory. Such analysis reveals how damnatio memoriae helps elites to redefine the “memory” of the Eternal City.

Effects of receipt of Social Security retirement benefits on older women’s employment

Labor force participation of women has declined since 1999; however, labor force participation of women 62+ has increased. The 2000–2006 waves of Health and Retirement Study (HRS) data, the initial years of the continuing upward trajectory, were used to test the effects of receipt of Social Security retirement benefits on older women’s employment. The models tested: (a) the effect of receipt of Social Security retirement benefits on whether employed; and (b) for women receiving Social Security retirement benefits, the effect of age elected receipt of benefits on whether employed. Both models included the effects of human capital characteristics and income sources. Receipt of Social Security benefits, pension income, and current age reduced the likelihood of employment; while educational level, good to excellent health, and nonmarried marital status increased the likelihood of employment. The older the woman was when she elected Social Security benefits, the more likely she was to be employed.     

Ethnic differences in the labour market: a comparison of the samples of anonymized records and Labour Force Survey

The public use sample from the 1991 UK census makes it possible to conduct individual level analyses of ethnic minorities' educational and occupational attainments. Unfortunately, however, the census asked only about higher level qualifications obtained after reaching 18 years of age. A comparison with the Labour Force Surveys (LFSs) shows that the census gives in some respects a misleading impression of qualifications among the first-generation members of ethnic minorities: the LFS data show that ethnic minorities tend to be more polarized in their qualifications than the British-born whites, with relatively large proportions at the two extremes, either with degrees or with no qualifications at all. It follows that the census's treatment of qualifications may tend to exaggerate the scale of disadvantage of ethnic minorities in the labour market, and particularly in access to the salariat where qualifications play a particularly large role in recruitment. Regression analyses of sample of anonymized records and LFS data confirm these expectations although they indicate that the results of the census are not seriously misleading as regards the pattern of ethnic disadvantages in the competition to avoid unemployment. The LFS data also confirm earlier findings that the ethnic penalties are in general of similar magnitude among the second generation to those among the first generation, despite the substantial equalization of educational experience that has taken place. There is some evidence that disadvantages in access to the salariat may have been reduced, but this is counterbalanced by the evidence that disadvantages in the avoidance of unemployment may have deteriorated.     

Future challenges for parenting education and support

The authors of this special edition of Child Welfare have shared current shifts in perspective about parenting and parenting education that are raising some interesting challenges. We will first briefly review the shifts identified in the articles presented here. Second, we will raise questions about the implications of these shifts for the field of parenting education.     

Parenting: a relationship-oriented and competency-based process

Parents have a complex task of guiding a specific child to maturity by using the opportunities offered by the environment, while avoiding its detrimental aspects. This article develops a theory of the parenting process that describes components of the parental role; situations where development and, thus, parenting occurs; the responsibility of parents in those situations; the attributes parents use to fulfill their role; and implications for professionals.     

Detecting Overdispersion in Large Scale Surveys: Application to a Study of Education and Social Class in Britain (with Comments)

A practical problem with large scale survey data is the potential for overdispersion. Overdispersion occurs when the data display more variability than is predicted by the variance–mean relationship for the assumed sampling model. This paper describes a simple strategy for detecting and adjusting for overdispersion in large scale survey data. The method is primarily motivated by data on the relationship between social class and educational attainment obtained from a 2% sample from the 1991 census of the population of Great Britain. Overdispersion can be detected by first grouping the data into a number of strata of approximately equal size. Under the assumption that the observations are independent and there is no variability in the parameter of interest, there is a direct relationship between the nominal standard errors and the empirical or sample standard deviation of the parameter estimates obtained from each of the separate strata. With the 2% sample from the British census data, quite a discernible departure from this relationship was found, indicating overdispersion. After allowing for overdispersion, improved and more realistic measures of precision of the strength of the social class–education associations were obtained.     

Mapping of population density

The Bureau of the Census listing of geographical coordinates of centroids of all enumeration districts together with population counts from the U. S. 1970 Census of Population was used to contruct via computer five nationwide geographical grids of population density with sector dimensions of 0.01, 0.02, 0.04, 0.1, and 0.25 degrees of latitude and longitude. The entire population of a district was assigned to a grid sector if the coordinates of the district centroid fell within the boundaries of the sector. The sectors were then rank-ordered according to population density, and listings were made of sector population, population density, geographical location, cumulative population, area of sector, and cumulative area. The five sets of data were synthesized into single equations describing population as a function of density in one case and of area in another. From these data it was found, for example, that about 800,000 people live in 19 sectors of 0.01-degree dimensions with a population density of 100,000 people per square mile or greater (nearly all in Manhattan); about 10 million live in 183 sectors of 0.02-degree dimensions with a population density of 23,000 per square mile or greater; and about half of the total U. S. population, that is, about 100 million people, reside within about 0.6 percent of the area of the United States, that is, within 20,000 square miles.Four representative displays of population density are shown for the Northeast Corridor, including isometric views and a contour map.     

Evacuating People with Mobility‐Challenges in a Short‐Notice Disaster

In past disasters, arrangements have been made to evacuate people without their own transportation, requiring them to gather at select locations to be evacuated. Unfortunately, this type of plan does not help those people who are unable to move themselves to the designated meeting locations. In the United States, according to the Post‐Katrina Emergency Management Reform Act of 2006, state or local governments have the responsibility to coordinate evacuation plans for all populations. These include those with disabilities. However, few, if any, have plans in place for those who are mobility‐challenged. The problem of evacuating mobility‐challenged people from their individual locations in a short‐notice disaster is a challenging combinatorial optimization problem. In order to develop the model and select a solution approach, we surveyed related literature. Based on our review, we formulate the problem and develop an Ant Colony Optimization (ACO) algorithm to solve it. We then test two different versions of the ACO algorithm on five stylized datasets with several different parameter settings.
