Allele frequencies for 15 autosomal STR loci and admixture estimates in Puerto Rican Americans

Allelic frequencies of 15 short tandem repeats (STR) markers (CSF1PO, FGA, THO1, TPOX, VWA, D3S11358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, D19S433 and D2S1338) were determined using the AmpFl STR Identifiler PCR Amplification Kit in Puerto Rican American individuals (N=205) from Massachusetts. The FGA, D18S51 and D2S1338 loci had a high power of discrimination (PD) with values of 0.967, 0.965 and 0.961, respectively. Significant deviations from the Hardy-Weinberg (HW) equilibrium were not detected. An important genetic contribution of Caucasian European (76.4%) was detected in Puerto Rican Americans. However, comparative analysis between Puerto Rican American and other neighboring populations from United States mainly with African and Caucasian Americans, revealed significant differences in the distribution of STR markers. Our results are important for future comparative genetic studies of different American ethnic groups, in particular a cultural group called Hispanic-Americans and should be helpful for forensic and paternity testing.     

Psychosocial Adjustment and Family Relationships: A Typology of Italian Families with a Late Adolescent

The importance of family relationships in human development and adjustment has always been recognized in psychological studies. The present study aims to construct a typology of families with a late adolescent and to analyze the family relationships present in each type. The typology, constructed using family satisfaction—a global index of family functioning—as the discriminate variable, took into account eight types. This study is focused on the two extreme types of the typology: Families with adequate functioning or satisfied families and Families with inadequate functioning or dissatisfied families. These two types of families were compared according to variables such as: (a) parent-child communication and its topics and (b) the family's decision-making process on topics related to the adolescent and his/her future orientation. All subjects completed a questionnaire composed of different scales. The results show substantial differences in the two family types regarding both family functioning and the role played by mothers and fathers. Satisfied families give evidence of a better communication process than the dissatisfied ones, greater sharing between parents and adolescents and, finally, a decision-making process based mostly on sharing and support. Moreover, in satisfied families the father has the role of social mediator. In this way, he succeeds in part in restoring equilibrium to the relational imbalance in favor of mothers so typical of Italian families.     

Perception of infant cries in adolescent and adult mothers

Deficits in parenting behavior in adolescent mothers could be due to the adolescent mother's perception of her infant's behavior. The aim of this study was to compare how adolescent and adult mothers perceive the crying behavior of their newborns. The 19 adolescent and 18 adult mothers listened to a tape recording of their infants' crying and rated the characteristics of the cry on 12 seven-point scales. The sample included newborns with normal growth and newborns with compromised growth. Acoustic characteristics of the cries were extracted by computer. Adult mothers rated the cries of their infants with compromised growth toward the negative end of the scales. By contrast, adolescent mothers rated the cries of their infants with compromised growth toward the positive end of the scales. Acoustic analysis showed that the cries of the infants with compromised growth were higher pitched and more variable than the cries of infants with normal growth. Correlations between the cry ratings and the acoustic analysis showed that for adult mothers, higher pitched and more variable cries were associated with negative ratings. For adolescent mothers, higher pitched and more variable cries were associated with more positive ratings. The findings suggest that adolescent mothers differ in the perception of their infant's behavior, which may have implications for later parenting behavior.This research was supported by a grant from the Ford Foundation.Received Ph.D. from Michigan State University.

Validation of a radiographic method to establish new fetal growth standards: radio-anatomical correlation

In forensic medicine, specialists might face difficulties when estimating age at death from fetal remains. Depending on the state of preservation, this age assessment is essentially based on the diaphyseal size of long bones. In a previous work, for the measurement of fetal femoral ossified shafts, we already established a simple and reliable method using a radiographic protocol. Since we previously stated that radiographic measurement values were closer to real anatomical size than ultrasonographic ones, in the present study we decided to check the importance of the difference between radiographic and anatomical measurements. Therefore, we dissected 30 pairs of fetal femurs and compared the difference between the two kinds of measurements (in percentages). This difference seemed to be slight (4.027%), but it was large enough to entail significant differences (p < 0.001). In order to provide a correction factor for radiographic measurements, we established a linear regression formula, which was tested on another sample of 30 pairs of dissected femurs. As a consequence of the good results, we improved the linear regression using a powerful statistical tool: the bootstrap. Finally, we obtained a simple equation that allowed us to figure out the real anatomical size with an R2 of 99% and a mean relative difference of 0.153% (with a standard error of 0.252 mm, and therefore a 95% confidence interval with limits of -0.35 and 0.657 mm). This difference did not entail any significant differences (p = 0.498), and therefore, we concluded that with the proposed correction, radiographic measurements can easily be used by forensic specialists in their daily tasks or to establish new growth standards in order to best fit their population of interest.     

‘Recovering’ Territories: The Use of History in the Integration of the New Polish Western Borderland after World War II*

This article analyses the historical narrative about the territories annexed by Poland from Germany at the end of World War II. The so-called ‘Recovered Territories’ were reinterpreted as ‘ancient Slavonic lands’, which had been unlawfully seized by Germans and only now restored to their rightful owners. The aim was to establish authority over the acquired territories, integrate them with the rest of Poland and build a sense of identity with them. At the same time, scholarship entered into a complex relation with the new communist regime, joined by the common interest of establishing the new Polish–German border.     

Intergovernmental relations on immigrant integration in Spain: The case of Catalonia

ABSTRACT

This paper examines the nature of intergovernmental relations (IGR) on immigrant integration in Spain, a relatively recent immigration country, with a focus on Catalonia. By means of qualitative document analysis and semi-structured interviews at both levels of government, the paper demonstrates that despite the formal existence of multilateral and institutionalized fora for intergovernmental relations, most intergovernmental relations on immigrant integration tend to be informal and bilateral. The paper also highlights that the conflictual nature of IGR on integration varies across sub-policy areas and over time. The paper contributes to strengthen existing hypotheses regarding institutional features (the distribution of competencies and the territorial organization of power) and party politics for explaining the patterns of IGR.     

Confirmation by LC–MS of drugs in oral fluid obtained from roadside testing

The aim of this study was to assess the effectiveness of two current on-site oral fluid (OF) drug detection devices (OraLab and Dräger), as part of the Spanish participation in the Roadside Testing Assessment Project (ROSITA Project). The study was done in collaboration with the Spanish Traffic Police, in Galicia (NW Spain), during 2004 and 2005. A total of 468 drivers selected at the police controls agreed to participate through informed consent. In addition, saliva samples were collected and sent to the laboratory to confirm the on-site results. For this purpose, two different analytical liquid chromatography–mass spectrometry (LC–MS) methods were used to detect 11 drugs or metabolites in a 300 μL sample. Simultaneous analysis of morphine, 6-acetylmorphine, amphetamine, methamphetamine, MDA, MDMA, MDEA, MBDB, cocaine and benzoylecgonine was carried out using 100 μL of oral fluid, after an automated solid phase extraction. A different LC–MS method was performed to detect Δ⁹-THC in 200 μL of oral fluid using liquid–liquid extraction with hexane at pH 6. Both methods were fully validated, including linearity (1–250 ng/mL, 2–250 ng/mL) recovery (>50%), within-day and between-day precision (CV < 15%), accuracy (mean relative error < 15%), limit of detection (0.5 and 1 ng/mL), quantitation (1 and 2 ng/mL) and matrix effect. All of the positive cases and a random selection of 30% of the negatives were analyzed for confirmation analysis. Good results (sensitivity, specificity, accuracy, positive predictive value and negative predictive value > 90%) were obtained for cocaine and opiates by OraLab, and for cocaine by Dräger. However, the results for the other compounds could be improved for both detection devices. Differences in the ease of use and in the interpretation mode (visual or instrumental) were observed.
