Population data for 15 Y-chromosome STRs in a population sample from Quito (Ecuador)

Population frequencies for the 9 Y-STR loci included in the "minimal haplotype" from Y-STR Haplotype Reference Database (YHRD), plus other 6 Y-STRs (DYS437, DYS438, DYS439, GATA A7.2, GATA H4 and GATA A10) were obtained for a sample of 120 males from Quito (Ecuador). One hundred and sixteen unique haplotypes were identified within the sample. Haplotype diversity (0.9994) was among the highest in comparison to other populations from Iberia and South-America. Genetic distances were calculated and our sample presented significative differences with all other samples, the lowest values being with a Guinean sample.     

Effectiveness of comparison overlays generated with DentalPrint software in bite mark analysis

Validation studies of the new DentalPrint software were carried out with experimental bite marks in pigskin. The bite marks were digitally photographed according to the ABFO guidelines for evidence collection. Dental casts used in the experiment were scanned in 3D and 2D, and comparison overlays were generated using DentalPrint and Adobe Photoshop software, respectively. Digitized photographs of the experimental bite marks and the biting edges obtained in the overlays were compared by two different examiners to analyze the impact of training and experience with the two methods. Receiver operating characteristic (ROC) analysis, sensitivity, specificity, and 95% confidence intervals for each cutoff point were calculated. The expert examiner using DentalPrint obtained the best results, with an area under the ROC curve of 0.76 (SE=0.057; CI at 95%=0.652-0.876). Fairly high specificity values were found for DentalPrint, and the best results were obtained for the cutoff value that discriminated between the examiner's response "biter" and the rest of the possible (specificity 97.9%, CI at 95%=93.2%-99.6%). Therefore, the results presented here indicate that DentalPrint is a useful, accurate tool for forensic purposes, although further research on the comparison process is needed to enhance the validity of bite mark analysis.

Advocates for hire: How government contracting shapes politics

Many public services in the United States are administered through non-state actors, many of which are nonprofits with broad social missions. Some scholars show that contracting these organizations can compromise their broader goals and political activities, while others find that such arrangements empower the organizations to engage in advocacy and influence policy. We argue that not only can contracting strengthen nonprofits' capacities to engage in politics and advance their missions, but it can mobilize political activity among those working for and engaging with the nonprofits. We use the case of Teach For America (TFA) and an instrumental variable approach that leverages plausibly exogenous variation in the timing of TFA's arrival in states to show that contracting TFA is related with the arrival of new education reform advocacy groups spearheaded by TFA alumni. This, in addition to TFA's direct efforts, leads to the passage of reform policies—especially charter school laws.     

The role of 'the resources of the power hypothesis' in explaining the Spanish welfare state between 1975–1995

There are two clearly differentiated parts to this work. The first consists of a review of the theoretical arguments that underlie the so–called 'resources of power hypothesis' . That theory has been used to explain the growth and development of the Welfare State in several European countries. The findings of a number of empirical works backing up that theory have also been included in this review. The intention of the second part is to check the theory against the Spanish case between 1975 and 1995. The conclusion of this work is that if, besides considering the ideological persuasion of the party controlling the government, we take into account the other relevant factors encompassed by the theory, then the 'resources of power hypothesis' is valid in explaining and interpreting the make–up and scope of the Spanish Welfare State.     

The False Narrative On Basic Rights

正The U.S. has made human rights a central component of its foreign policy since the Jimmy Carter administration(1977-81). Carter, seeking to improve the international image of the U.S. in the aftermath of the Viet Nam War, criticized human rights abuses and the lack of political freedoms in various U.S.-allied dictatorships, including Chile and Nicaragua. Such criticisms were designed not only to enhance the reputation of the U.S. internationally but also to buttress and give credibility to its ongoing ideological warfare against the socialist world.     

Moderating Factors in Adopting Local e-Government in Spain

This study analyses the factors that influence citizens' intention to use e-government activities offered by municipalities in Spain. For this purpose, we developed a straightforward user behaviour model that considers the components of the TAM and DOI models simultaneously, harnessing their synergies and factoring in the role of citizens' trust. We also examined the moderating role that population size can play in the model's behaviour. Among the results we obtained, it is important to note that user trust not only improved the model's fit, but also showed a significant effect on intention of use for all the population sizes that we analysed. The other significant relationship for all the samples linked ease of use to perceived usefulness. For the other relationships between variables, we observed the moderating role of size for the populations we considered.
