This article attempts to build bridges in the formal study of policymaking across polities of different degrees of institutional development. It explores the reasons why policymaking is fairly institutionalized in some polities but not in others. It suggests extending standard models of institutionalized policymaking to allow for a wider set of actions, including the threat of violence or of damage to the economy. It engages the discussion of institutions as rules and institutions as equilibria, delivering multiple equilibria with different degrees of institutionalization. The likelihood of institutionalized policymaking increases as the cost of alternative political actions increases, as the damage these alternatives cause decreases, and as the economy becomes wealthier. In cases in which the distribution of de jure political power is more asymmetric, it is more likely to observe use of alternative political technologies as well as low degrees of institutionalization. 相似文献

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. 相似文献

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. 相似文献

This work deals with the study of the evolution and the historical experience of Spanish journalism in the context of decades of transition between the nineteenth and twentieth centuries. From the selection of the most relevant cases and the examination of tracking, or not, of models and European patterns of the reference press, singularities and analogies of the historical evolution of the Spanish journalism model may be seen – an evolutionary model fully registered within the framework of Western Europe and in one of its most fruitful phases: the origins and first development of the mass media. Therefore, the following trilogy of reference media is selected covering specified time periods: El Imparcial, Madrid, 1867–1933; La Vanguardia, Barcelona, 1881; and ABC, Madrid, 1903. 相似文献

In this paper, we focus on the relationship between parents’ education and activities aimed at increasing the human capital of children (for example, educational childcare). Using time use surveys from Mexico, Peru, Ecuador, and Colombia we find that in Mexico, Peru, and Colombia the level of education of both father and mother has a positive association with the time devoted to educational childcare, while in Ecuador only fathers’ level of education has a positive association with father’s time devoted to educational childcare. Furthermore, we find that the time devoted to educational childcare by parents is positively related in all four countries. 相似文献

Objective: To examine gender differences in demography, cooccurrence of Diagnostic Statistical Manual (third edition, revised; DSM-III-R) axis I disorders and axis II personality disorders, and self-reported psychological distress in adolescent psychiatric inpatients with alcohol use disorders. Method: A consecutive series of 61 adolescent inpatients (36 boys and 25 girls) with either alcohol abuse or dependence were reliably assessed with structured diagnostic interviews for DSM-III-R Axis I and Axis II personality disorders. Results: Boys and girls did not differ in age, ethnicity, socioeconomic status, global functioning, age at first psychiatric contact, or number of hospitalizations. Girls were more likely to meet criteria for oppositional defiant disorder, eating disorders, and additional drug use disorders. Girls were also more likely than boys to meet criteria for at least one personality disorder and borderline personality Contrary to gender patterns in the general population, the proportion of girls and boys with affective disorders and conduct disorders did not differ significantly. Conclusions: Relatively few gender differences were found in adolescent inpatient alcohol abusers even where they would be expected, based on non substance-abuse general population gender patterns. When observed, gender differences were in the direction of greater psychiatric disturbance among girls. Some of the gender patterns observed among alcohol abusing adolescents are at odds with gender differences observed in non substance-abuse samples. 相似文献

Long-term effects of participation in the Baltimore City drug treatment court: Results from an experimental study 总被引:2,自引:1,他引:1

This study uses an experimental design comparing 235 offenders assigned either to drug treatment court or treatment as usual.
It extends prior analyses of this study sample to examine whether differences observed between drug treatment court subjects
and control subjects at one and two years after the start of the program persist after three years, when many of the subjects
had ceased active treatment. Further, it extends earlier analyses that showed that the quantity of drug treatment court services
received was related to lower recidivism rates by using an instrumental variables approach to handle the endogeneity problem
that sometimes arises when subjects self-select into different levels of service. Results show a sustained treatment effect
on recidivism, controlling for time at risk. This effect is not limited to the period during which services are delivered.
Rather, it persists even after participation in the drug court program ceases. Results also show that the recidivism is lowest
among subjects who participate at higher levels in certified drug treatment, status hearings, and drug testing. These positive
findings are tempered with findings that more than three-fourths of clients are re-arrested within three years, regardless
of participation in the drug treatment court, and that drug treatment court cases spend approximately the same number of days
incarcerated as do control cases. Implications for strengthening drug treatment courts are discussed. 相似文献
