Combining Food Frequency and Survey Data to Quantify Long-Term Dietary Exposure: A Methyl Mercury Case Study

Twenty-four-hour recall data from the Continuing Survey of Food Intake by Individuals (CSFII) are frequently used to estimate dietary exposure for risk assessment. Food frequency questionnaires are traditional instruments of epidemiological research; however, their application in dietary exposure and risk assessment has been limited. This article presents a probabilistic method of bridging the National Health and Nutrition Examination Survey (NHANES) food frequency and the CSFII data to estimate longitudinal (usual) intake, using a case study of seafood mercury exposures for two population subgroups (females 16 to 49 years and children 1 to 5 years). Two hundred forty-nine CSFII food codes were mapped into 28 NHANES fish/shellfish categories. FDA and state/local seafood mercury data were used. A uniform distribution with minimum and maximum blood-diet ratios of 0.66 to 1.07 was assumed. A probabilistic assessment was conducted to estimate distributions of individual 30-day average daily fish/shellfish intakes, methyl mercury exposure, and blood levels. The upper percentile estimates of fish and shellfish intakes based on the 30-day daily averages were lower than those based on two- and three-day daily averages. These results support previous findings that distributions of "usual" intakes based on a small number of consumption days provide overestimates in the upper percentiles. About 10% of the females (16 to 49 years) and children (1 to 5 years) may be exposed to mercury levels above the EPA's RfD. The predicted 75th and 90th percentile blood mercury levels for the females in the 16-to-49-year group were similar to those reported by NHANES. The predicted 90th percentile blood mercury levels for children in the 1-to-5-year subgroup was similar to NHANES and the 75th percentile estimates were slightly above the NHANES.     

Interjurisdictional placement of children in foster care

As the population of children in foster care has increased and more children are freed for adoption, foster and adoptive families are needed in ever increasing numbers. One avenue for expanding the pool of families is through placement of children with families in other counties and states. This article considers the policy and practice implications of interjurisdictional placement in the context of foster care, adoption, and kinship care and suggests directions for interjurisdictional adoption practice and policy.     

Imaginandose Mexicano: The Symbolic Context of Mexican American Ethnicity Beyond the Second Generation

This study explores how third-plus-generation Mexican Americans are able to perpetuate Mexican ethnicity within the relatively integrated environments they occupy in and around Phoenix, Arizona and San Jose, California. By using an imaginary approach in this analysis, I seek to demonstrate the limited applicability of the symbolic ethnicity approach for this group, in particular, as well as to downplay thinking about culture as a set of traits or fixed characteristics that define an ethnic subgroup. I do this through an exploration of how the third-plus-generation Mexican Americans interviewed for this study utilize a range of relational resources—specifically, religion, Spanish-language television, and cross-national encounters—to reinforce and recreate Mexican ethnicity in their day-to-day lives.     

Cognitive-behavioral treatment for adolescents who sexually offend and their families: individual and family applications in a collaborative outpatient program

This article describes an outpatient treatment program for adolescent sexual abusers that was established by a mental health agency in collaboration with a specialized probation program in the juvenile court. Individualized treatment is based on a comprehensive clinical assessment with the youth and guardian, for which examples are provided. Given the heterogeneity of this population, we describe several treatment strategies directed to various individual or family clinical targets, including psychiatric disorders, sexual deviance and sexuality, normal adolescent development and adaptive skills, and parent and family relationships. Ongoing collaborative and coordination issues are also reviewed. The integration of mental health and probationary services provides a balanced approach to the community management and treatment of the low-risk, primarily first-time, adolescent sexual offender.     

Relational networks: An extension of sociometric concepts

Conventional dyadic sociometric techniques are shown to be inadequate for dealing with substantively important complex relationships. An extension of the concept of relationship is proposed to encompass these more complex structures, and some elementary formal properties of the resulting networks (known as bipartite graphs) are examined. Preliminary applications are made to problems concerning partitions of a population induced by a structure and boundaries of observability in organizations.     

Evaluating the administrative efficiency of courts

In addition to being held accountable for judicial decision, courts, like other public agencies, can and should be evaluated in terms of their administrative efficiency. This paper illustrates how courts can be evaluated in terms of their relative administrative efficiency, using a new approach—data envelopment analysis (DEA)—first proposed by Charnes et al. [1]. The DEA is based upon the economic notion of Pareto optimality which states that a given decision making unit (DMU) is inefficient if some other DMU, or some combination of other DMUs, can produce at least the same amounts of all outputs with less of some resource input and not more of any other resource. Conversely a DMU is said to be efficient if the above is not possible. Charnes et al. [1] generalized the usual input/output ratio measure of efficiency for a given unit in terms of a fractional linear program with fractional constraints. In the case of courts, the efficiency of any particular court is calculated by forming the ratio of a weighted sum of outputs to a weighted sum of inputs, where the weights for both outputs and inputs are to be selected in a manner that calculates the Pareto-Koopmans efficiency of the court. This paper reviews the DEA method and illustrates its application to a data base for 100 criminal superior courts in North Carolina.     

Integrating research,policy, and practice in juvenile justice education

This article provides an overview of the history and context leading to Florida's efforts to implement an evaluation-driven research and associated quality assurance system for its juvenile justice education policies and practices. The Juvenile Justice Educational Enhancement Program began implementing Florida's evaluation research and quality assurance system to juvenile justice education in 1998. The article includes a brief summary of articles comprising this special issue of Evaluation Review that address the Juvenile Justice Educational Enhancement Program's various functions, methodological components, data, preliminary findings, continuing evaluation research efforts, and impediments.     

Evaluation research,policy, and politics

This article discusses the role of politics in the Juvenile Justice Educational Enhancement Program's effort to use evaluation research data to inform Florida's juvenile justice education policies and practices. Through consideration of the Juvenile Justice Education Enhancement Program's experiences with privatization and the tough love and economy of scale rationales for larger and more custodial juvenile institutions, the variable role of politics is examined. Although the two examples are different, the discussion demonstrates that by maintaining an overriding commitment to its evaluation research purpose, the Juvenile Justice Educational Enhancement Program has been able to continue its data-driven policy efforts despite operating in a politically charged environment.
