Estimating Age: College Males Versus Convicted Male Child Sex Offenders

Two samples, male college students and convicted male child sex offenders, are compared on their abilities to accurately estimate the age group of a series of photographs of a sole female ranging in age from 11 to 29. Both samples tend to overestimate the age group of the subject photos, and no significant difference was found between college students and convicted child sex offenders in their ability to estimate the age of females. Both groups are compared demographically, and only limited differences were found. The implications are discussed in regard to theory and prevention of child sexual abuse.     

Using experiential knowledge to understand urban rat ecology: A survey of Canadian pest control professionals

Rats (Rattus rattus and Rattus norvegicus) are among the most prolific and widespread urban pest species in the world. However, there is relatively little contemporary data regarding the ecology of rats in urban centers, preventing the development of effective strategies for urban rat management. Practical constraints associated with field studies suggest the need for more efficient methods of data collection, one of which could involve pest control professionals, who have considerable experiential knowledge of urban rats. The objective of this study was to gather data regarding urban rat ecology through a survey of Canadian pest control professionals and to determine whether such a survey could be useful for the collection of ecological data regarding pest species. Survey results suggested that rat infestations fluctuate seasonally and that there are a variety of environmental factors that may attract rats, particularly exposed garbage, abandoned buildings, and compost. Respondents suggested that rat infestations are most frequent and/or severe in residential areas, commercial areas dealing with food, as well as in neighborhoods of low socioeconomic status. The majority of respondents believed that rats pose at least a moderate health risk to the general public and to themselves, and they also believed that although poison baiting is the cheapest and easiest method of rat control, environmental modification is the most effective way to control rat infestations in the long term. Despite issues with low response rates, these results suggest that pest control professionals may be a valuable source of data regarding urban pest species.     

Congressional passage of the Chinese exclusion act of 1882

The Chinese Exclusion Act of 1882 marked an important turning point in the history of American race relations. According to the Act, the immigration of Chinese to the United States was completely halted. Chinese were thus excluded from the possibility of American citizenship. Previous studies on the Chinese Exclusion Act have found that the act was largely successful in systematically denying Chinese‐Americans their civil rights and for decades excluding them from the shores of the United States. Prior research, however, has tended to focus on the results of the act and has neglected a systematic analysis of the congressional vote on the act. Our study will examine the events leading up to the Chinese Exclusion Act in order to achieve a better understanding of the dynamics of the vote on the Act and conclude with a quantitative analysis of the vote on the bill in the House of Representatives in 1882. Our findings indicate that the House was severely divided on the issue of Chinese exclusion on partisan and regional lines.     

Extending the Lee-Carter Method to Model the Rotation of Age Patterns of Mortality Decline for Long-Term Projections

In developed countries, mortality decline is decelerating at younger ages and accelerating at old ages, a phenomenon we call “rotation.” We expect that this rotation will also occur in developing countries as they attain high life expectancies. But the rotation is subtle and has proved difficult to handle in mortality models that include all age groups. Without taking it into account, however, long-term mortality projections will produce questionable results. We simplify the problem by focusing on the relative magnitude of death rates at two ages (0 and 15–19) while making assumptions about changes in rates of decline at other ages. We extend the Lee-Carter method to incorporate this subtle rotation in projection. We suggest that the extended Lee-Carter method could provide plausible projections of the age pattern of mortality for populations, including those that currently have very high life expectancies. Detailed examples are given using data from Japan and the United States.     

Quality and the 2010 Census

The U.S. Census Bureau has a long tradition of evaluating the results of its censuses. This paper presents evaluation results from the 2010 Census, comparing them to earlier results. The paper discusses net coverage at the national and state level, as well as by age, sex, race, and ethnic group. It discusses components of error, including estimated number missed and counted in error. It also presents data on whole-person and item imputation.     

Our People First!' Understanding the Resonance of the Vlaams Blok's Xenophobic Programme

This article begins with a critical appraisal of some of the more general accounts of the recent rise of the xenophobic right, subsequently arguing that these explanations are necessarily incomplete and perhaps misleading int heir attempts at universality. It is argued that a more useful method of analysis must problematise the very contention of social difference on which these movements are based, and focus on nationalism as a mode of claim making embedded in a complex and historicallycontingent process of socio-political change. Using Flemish nationalism, and more particularly the xenophobic Vlaams Blok party, as a case study, the author shows the value of an historically-sensitive account which re-incorporates nationalism into its political context.     

The Model Development Dissertation

ABSTRACT

Asset-building programs, such as Individual Development Account (IDA) programs within social service agencies, assist low-income employed clients in building credit, purchasing affordable assets, and gaining wealth. This longitudinal exploratory study examines the credit outcomes of IDA programs to add to the knowledge concerning the effects of IDAs as an asset-building tool. Data were analyzed using a convenience sample of IDA participants and nonparticipants (N = 164), and the results indicated that initial credit score and history are associated with program participation. However, results also suggested that initial credit score is not a meaningful indicator of program completion, time to completion, or type of asset purchased for participants. Those who completed the IDA program within 2 years experienced the highest credit gains. Future research with larger samples is needed to further assess the impact of credit on program participation and completion and on whether credit gains are sustained.     

Understanding the cultural adaptation of foreign wives of South Korean men

‘International marriage’ has increased within rural areas in South Korea. As an increasing number of rural women move to urban areas, men are left facing the challenges of finding appropriate spouses. This issue stimulated support for ‘international marriages’ by the Korean government. A review was carried out of the literature of foreign wives' cultural adaptation in South Korea using the ecological systems. While foreign wives have escaped the hardships of lower economic status in their home country, they often face new challenges in South Korea. The article recommends that one-stop multicultural services are needed to address the cultural issues facing non-Korean women.     

An Experiment on the Measurement of Political Knowledge in Surveys

In a series of articles, Mondak and colleagues argue that theconventional way of measuring political knowledge in surveysis flawed. Personality related "propensity to guess" underestimatesthe level of political knowledge in the population and distortsestimates of between group differences, when a DK alternativeis offered. This has led Mondak to recommend the use of closed-endeditems on which DKs are not explicitly offered, following bestpractice in the field of educational testing. In this article,we present the results of an experimental study which callsinto question the wisdom of this approach. Our results showlittle evidence of partial knowledge concealed within DK responses;when people who initially select a DK alternative are subsequentlyasked to provide a "best guess," they fare statistically nobetter than chance. We conclude that opinion researchers shouldbe cautious about adopting Mondak's recommendations for thedesign of political knowledge items in surveys. Received for publication February 22, 2005.
