Distributions of genetic markers in United States populations: I. Blood group and secretor systems

All published and unpublished population frequency data that could be located for U.S. populations are tabulated and presented for the blood group and secretor systems. Results obtained by combining data for comparable racial/ethnic groups are also presented. The results obtained with combined data may give better information on frequencies for the U.S. population at large than is obtainable from studies conducted in restricted geographic areas.     

Distributions of genetic markers in United States populations: II. Isoenzyme systems

All published and unpublished population frequency data that could be located for U.S. populations is tabulated and presented for the isoenzyme systems phosphoglucomutase, esterase D, adenylate kinase, acid phosphatase, glyoxalase I, adenosine deaminase, 6-phosphogluconate dehydrogenase, glutamic-pyruvic transaminase, carbonic anhydrase II, and glucose-6-phosphate dehydrogenase. Results obtained by combining data for comparable racial/ethnic groups are also presented. The results obtained with combined data may give better information on frequencies for the U.S. population at large than is obtainable from studies conducted in restricted geographic areas.     

Demographic change and forensic identification: problems in metric identification of Hispanic skeletons

The United States (U.S.) population structure is currently in a state of flux with one of the most profound changes being the increasing number of people referred to as Hispanic. In the U.S., much of the identification criteria for a biological profile are based on American Black and White individuals from anatomical collections. Using metric data from the Forensic Anthropology Data Bank (FDB), this paper will attempt to explore several issues that forensic anthropologists face when confronted with Hispanic remains. These will involve estimation of sex, height, and ancestry, the initial components of a biological profile. Discriminant function analyses indicate that American White criteria provide poor estimations of sex when applied to Hispanics and that ancestry estimation of Hispanic crania is difficult. Additionally, a new linear regression equation is presented that estimates stature for Hispanic individuals, although population specific criteria are still needed for Hispanic individuals from diverse geographical origins.     

ETHNIC THREAT AND SOCIAL CONTROL: EXAMINING PUBLIC SUPPORT FOR JUDICIAL USE OF ETHNICITY IN PUNISHMENT*

Research on social inequality in punishment has focused for a long time on the complex relationship among race, ethnicity, and criminal sentencing, with a particular interest in the theoretical importance that group threat plays in the exercise of social control in society. Prior research typically relies on aggregate measures of group threat and focuses on racial rather than on ethnic group composition. The current study uses data from a nationally representative sample of U.S. residents to investigate the influence of more proximate and diverse measures of ethnic group threat, examining public support for the judicial use of ethnic considerations in sentencing. Findings indicate that both aggregate and perceptual measures of threat influence popular support for ethnic disparity in punishment and that individual perceptions of criminal and economic threat are particularly important. Moreover, we find that perceived threat is conditioned by aggregate group threat contexts. Findings are discussed in relation to the growing Hispanic population in the rapidly changing demographic structure of U.S. society.

Diversity in Policing

Abstract

Police and minority relations have received much interest among public and academic audiences, yet little is known about policing in Latino communities. As Latinos emerge as the largest minority group in the United States, researchers and police agencies are increasingly concerned with the experience of Latinos in the criminal justice system. One strategy for improving police and community relations is to enhance the diversity of law enforcement agencies. Therefore, the purpose of this study is to examine the ethnic composition of law enforcement agencies in major U.S. metropolitan areas between 1990 and 2000. Using data from the U.S. Census and the Law Enforcement Management and Administrative Statistics (LEMAS) survey, it appears that the growth in the U.S. Latino population has been met with an increase in the percentage of Latinos as sworn full-time police officers. Further, the degree of enhanced diversity varies by the ethnic composition of the community served. Implications of findings for improving relations between police and the Latino community are discussed.     

Population data on the thirteen CODIS core short tandem repeat loci in African Americans, U.S. Caucasians, Hispanics, Bahamians, Jamaicans, and Trinidadians

Allele distributions for 13 tetrameric short tandem repeat (STR) loci, CSF1PO, FGA, TH01, TPOX, VWA, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, and D21S11, were determined in African American, United States Caucasian, Hispanic, Bahamian, Jamaican, and Trinidadian sample populations. There was little evidence for departures from Hardy-Weinberg expectations (HWE) in any of the populations. Based on the exact test, the loci that departed significantly from HWE are: D21S11 (p = 0.010, Bahamians); CSF1PO (p = 0.014, Trinidadians); TPOX (p = 0.011, Jamaicans and p = 0.035, U.S. Caucasians); and D16S539 (p = 0.043, Bahamians). After employing the Bonferroni correction for the number of loci analyzed (i.e., 13 loci per database), these observations are not likely to be significant. There is little evidence for association of alleles between the loci in these databases. The allelic frequency data are similar to other comparable data within the same major population group.     

Jordanian population data on the PCR-based loci: LDLR, GYPA, HBGG, D7S8 and GC.

Genotype and allele frequency distributions for PM polymerase chain reaction (PCR)-based genetic markers were determined in a Jordanian sample population. Results were obtained using the AmpliType PM PCR Amplification and typing kit. All loci were in agreement with the Hardy-Weinberg equilibrium expectations. The predominant alleles for LDLR, GYPA, HBGG, D7S8 and GC loci were B, A, B, A and C respectively. No statistically significant variation was detected in allele frequencies of these loci in Jordanians compared to that in Israeli Arab, U.S Caucasian and Japanese populations. Data presented here can be used to estimate the frequency of a specific DNA profile in the Jordanian population for forensic analyses and paternity testing.     

Population data on the D1S1656 and D12S391 STR loci in Andalusia (south Spain) and the maghreb (north Africa).

Allele and genotype frequencies for two tetrameric short tandem repeat (STR) loci were determined in two population samples, from Andalusia (S Spain; n = 127) and the Maghreb (N Africa; n = 40). After denaturing polyacrylamide gel electrophoresis, 14 alleles were identified for D12S391 and 13 alleles for D1S1656. No deviations from the Hardy-Weinberg equilibrium were detected. Some statistical parameters of forensic interest (H, PD, EC) were also calculated, and the data obtained for both populations were compared. Sequencing data of several intermediate D12S391 alleles designated 17.3, 18.3, and 19.3 are also presented.     

Exporting and importing criminality: Incarceration of the Foreign Born

Since previous studies have found that crime rates vary by immigrant group there is a need to dis‐aggregate immigrants by country of birth in order to obtain a more accurate representation of the relationship between migrants and crime. This study examines data from six countries (Australia, Canada, France, Italy, the Netherlands, and the U.S.A.) on the country of birth of their inmate populations. The following observations are reasonable conclusions from the data available. First, the percentages of each home country's inmate population that is foreign‐born varies remarkably. Second, in general foreign‐born inmates tend to come from regions outside the region within which the host country was located, though in most cases from regions that were proximate. Third, given the small number of countries reporting, it is intriguing that just a small number of countries and regions can account for such a high proportion of a home country's inmate population if one includes the numbers of a country's citizens who are housed in foreign prisons as part of that original country's inmate population. The paper concludes with a discussion of a number of policy implications that flow from these findings.     

The Slovenian population data on the PCR based loci HLA-DQA1, LDLR, GYPA, HBGG, D7S8, GC, and D1S80

Allele frequencies for the loci HLA-DQA1, LDLR, GYPA, HBGG, D7S8, GC, and D1S80 were determined for a sample population of unrelated individuals from Slovenia. All loci meet Hardy-Weinberg expectations, except the loci GYPA (p = 0.041) and D1S80 (p = 0.009). There is little evidence for association of alleles among the seven loci. Only one out of 21 pairwise comparisons demonstrated departures from independence (HLA-DQA1/HBGG, p = 0.008). The allelic frequency data generally are similar to that of U.S. Caucasians.     

A study on ten short tandem repeat systems: African immigrant and Spanish population data

This work presents the results obtained from a genetic-population study for the D1S1656 system in the population of Southwest Spain (Huelva, Cádiz and Sevilla), Spaniards of Caucasian origin from North Africa (Ceuta), as well as in the black Central West African and Moroccan immigrant populations in Spain. The results of a study of the autochtonous population of the Canary Islands (n=138), and immigrant Central West African populations in Spain (n=132), obtained for nine short tandem repeat (STR) loci (D3S1358, VWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820), as well as the amelogenin locus, all contained in Profiler Plus (Perkin-Elmer) PCR amplification kits, are also presented. Except for the FGA and VWA data on immigrant Central West African populations in Spain, no deviations from the Hardy-Weinberg equilibrium were detected.     

A study on ten short tandem repeat systems: African immigrant and Spanish population data

This work presents the results obtained from a genetic–population study for the D1S1656 system in the population of Southwest Spain (Huelva, Cádiz and Sevilla), Spaniards of Caucasian origin from North Africa (Ceuta), as well as in the black Central West African and Moroccan immigrant populations in Spain. The results of a study of the autochtonous population of the Canary Islands (n=138), and immigrant Central West African populations in Spain (n=132), obtained for nine short tandem repeat (STR) loci (D3S1358, VWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820), as well as the amelogenin locus, all contained in Profiler Plus™ (Perkin-Elmer) PCR amplification kits, are also presented. Except for the FGA and VWA data on immigrant Central West African populations in Spain, no deviations from the Hardy–Weinberg equilibrium were detected.     

The Impact of Gravity-Weighted Knowledge Spillovers on Productivity in Manufacturing

This paper tests for localized knowledge spillovers from out-of-state innovations in U.S. manufacturing from 1977 to 1997. The source of these spillovers is innovations categorized into six technologies based on U.S. patent classes and patent data. Using a gravity-weighting for out-of-state innovations, knowledge spillovers are found from mechanical technologies and drug and medical technologies for a broad group of manufacturing industries. Innovations from chemical-related technologies are found to generate spillovers for the Chemical and Allied Products Industry and for the Transportation Equipment Industry. Additionally, specialization of production at the two-digit Standard Industrial Classification of industry level is also found to increase state-level productivity in manufacturing.     

Mitochondrial DNA regions HVI and HVII population data.

Data from 1393 unrelated individuals have been compiled from eight population groups: African Americans, Africans (Sierra Leone), U.S. Caucasians, Austrians, French, Hispanics, Japanese, and Asian Americans. The majority of the mtDNA sequences were observed only once within each population group (i.e., ranging from a low of 60.3% (35/58) of the Asian American sequences to a high of 85.3% (93/109) of the French sequences). Genetic diversity ranged from 0.990 in the African sample to 0.998 in African Americans. Random match probability ranged from 2.50% in the Asian American sample to 0.52% in U.S. Caucasians. The average number of nucleotide differences between individuals in a database is greatest for the African American and African samples (14.1 and 13.1, respectively), and the least variable are the Caucasians (ranging from 7.2 to 8.4). Substitutions are the predominate polymorphism, and at least 92% of the substitutions are transitions. The most prevalent transversions are As substituted for Cs and Cs substituted for As. For most population groups these transversions occurred predominately in the HVI region; however, the African, African American, and Hispanic samples also demonstrated a large portion of their C to A and A to C transversions in the HVII region (at sites 186 and/or 189). Most insertions occur in the HVII region at sites 309.1 and 315.1, within a stretch of C's. Insertions of an additional C are common in all population groups. The sequence data were converted to SSO mtDNA types and compared with population data on Caucasians, Africans, Asians, Japanese, and Mexicans described by Stoneking et al. [M. Stoneking, D. Hedgecock, R.G. Higuchi, L. Vigilant, H.A. Erlich, Population variation of human mtDNA control region sequences detected by enzymatic amplification and sequence-specific oligonucleotide probes, Am. J. Hum. Genet. 48 (1991) 370-382] using an R x C contingency table test. Differences between major population groups (i.e., between African, Caucasian, and Asian) are quite evident, and similar ethnic population groups carried similar SSO polymorphism frequencies. There were only a few SSO types that showed significant differences between subpopulation groups. The SSO data alone can not be used to describe the population genetics with complete sequence data. However, the results of the SSO comparisons are similar to other analyses, and differences in sequence data in regions HVI and HVII are greater between major population groups than between subgroups.     

A method for subtyping group-specific component in bloodstains

A method is described for subtyping group-specific component (Gc) derived from human bloodstains. Bloodstained cuttings were extracted in 6 M urea. The extracts were subjected to ultrathin-layer polyacrylamide gel isoelectric focusing in the pH 4.5-5.4 range. After isoelectric focusing, Gc was detected by immunofixation in cellulose acetate membranes. This method permitted the successful typing of Gc in at least four-month-old bloodstains maintained at room temperature. Bloodstains from 266 liquid blood samples of known origin were subjected to both this method and immunofixation conventional agarose gel electrophoresis with no phenotypic discrepancies observed. The Gc population data for Whites from Baltimore, Maryland, were homogeneous with white sample populations from other geographical locations within the U.S.A.; while Gc data from northern U.S.A. black sample populations appeared to be heterogeneous compared with a southern United States black sample population.     

Intimate partner violence in the U.S. general population: progress and future directions

This article reviews survey research on intimate partner violence (IPV) in the U.S. general population. Results from survey research conducted over the past quarter century are briefly summarized. Three additional national studies related to injuries, crime victimization, and homicide among intimate partners in the United States are also considered. The article emphasizes the progress that has been made in general population survey research related to IPV. It concludes with a discussion of the current controversies and future directions for survey research of IPV in the U.S. general population.     

World population data for the HLA-DQA1, PM and D1S80 loci with least and most common profile frequencies for combinations of loci estimated following NRC II guidelines

All published and unpublished gene frequency data for the PCR-based loci HLA-DQA1, LDLR, GYPA, HBGG, D7S8, GC, and D1S80 that could be located are presented in summary tables. These gene frequencies provide the data necessary for estimating probabilities of chance match according to NRC II guidelines for any DNA profile that includes any combination of these loci for any of the populations. To illustrate the range of polymorphism for combined locus profiles, least and most common profile frequencies were estimated following NRC II guidelines for: the PM loci for all populations for which PM data were available; and for combinations of HLA-DQA1/PM, HLA-DQA1/D1S80, PM/D1S80, and HLA-DQA1/ PM/D1S80 for populations for which data were available for the relevant combinations. The profile frequencies were calculated at theta values of zero and 0.01. Minimum allele frequencies (MAF) were calculated, and are shown, for each data set for which the MAF was greater than the lowest observed allele frequency. Least common profile frequencies were calculated using MAF in those cases to illustrate a conservative estimate. The effect of using MAF versus lowest observed allele frequency in estimating least common profile frequencies is briefly illustrated as well. We finally show that aggregate U.S. gene frequency data for the classical MN and GC polymorphisms for both Caucasian and African-American populations is fully in accord with the DNA-based gene frequency data obtained from PM reverse dot-blot strips for GYPA and GC, respectively.     

Translating sexual assault prevention from a college campus to a United States military installation: piloting the know-your-power bystander social marketing campaign

One population that shares both similar and different characteristics with traditional college-age students is the U.S. Military. Similarities include a high concentration of 18- to 26-year-olds dealing with new found independence, peer pressure, and the presence of social norms that support violence and hypermasculinity. Sexual violence is a major public health problem in the United States, and because of the similarities in the age group of college and military populations, the problems regarding sexual violence in both constituencies have been well-documented. In the current pilot study we seek to add to both current knowledge about and promising practices of translating prevention strategies from one target audience to another. We describe how we translated, administered, and evaluated a bystander intervention social marketing campaign focused on sexual assault prevention that had been found to significantly affect attitude change on a college campus for a U.S. Army installation in Europe. In addition to demonstrating the process of translating prevention strategies across target audiences, findings from this pilot study contribute to the evaluation data on the effectiveness of sexual violence prevention strategies implemented with members of the U.S. Military. From our analysis, we see that research participants indicate that the degree to which the images resonate with them and the familiarity of the context (i.e., social self-identification) significantly effect the participants' personal responsibility for reducing sexual assault, confidence in acting as a bystander, and reported engagement as a bystander.     

CODIS STR loci data from 41 sample populations

Allele distributions for 12 or 13 CODIS core tetrameric short tandem repeat (STR) loci CSFIPO, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, FGA, TH01, TPOX, and vWA were determined in 41 population data sets. The major population groups comprise African Americans, U.S. Caucasians, Hispanics, Far East Asians, and Native Americans. There was little evidence for departures from Hardy-Weinberg expectations (HWE) in any of the populations. The FST estimates over all thirteen STR loci are 0.0006 for African Americans, -0.0005 for Caucasians, 0.0021 for Hispanics, 0.0039 for Asians, and 0.0282 for Native Americans.
