Is cooperation cost reducing? An analysis of public–public partnerships and inter-municipal cooperation in Brazilian local government

ABSTRACT

In local government systems worldwide, financial pressures have obliged local authorities to focus on cost-efficient methods for providing local services, including inter-municipal agreements and public–public partnerships. However, in comparison with municipal mergers, privatisation and other approaches to the problem, the cost impact of the cooperative provision has not yet been thoroughly examined empirically. Moreover, available empirical research has largely concentrated on waste disposal in developed countries. The present paper seeks to contribute to the empirical literature on inter-municipal agreements and public–public partnerships by comparing their impact on costs with ‘stand-alone’ provision in a range of non-waste local services. In contrast to the bulk of existing studies, our analysis takes place in a developing country context by examining Brazilian local government over the period 2013/15. We found that – on the whole – cooperative provision is less expensive than the ‘stand-alone’ provision for the services studied. Our results can be explained by the size and composition of the population, together with the politics for cooperation.     

The Use of Laser Microdissection in Forensic Sexual Assault Casework: Pros and Cons Compared to Standard Methods

Sexual assault samples are among the most frequently analyzed in a forensic laboratory. These account for almost half of all samples processed routinely, and a large portion of these cases remain unsolved. These samples often pose problems to traditional analytic methods of identification because they consist most frequently of cell mixtures from at least two contributors: the victim (usually female) and the perpetrator (usually male). In this study, we propose the use of current preliminary testing for sperm detection in order to determine the chances of success when faced with samples which can be good candidates to undergo analysis with the laser microdissection technology. Also, we used laser microdissection technology to capture fluorescently stained cells of interest differentiated by gender. Collected materials were then used for DNA genotyping with commercially available amplification kits such as Minifiler, Identifiler Plus, NGM, and Y‐Filer. Both the methodology and the quality of the results were evaluated to assess the pros and cons of laser microdissection compared with standard methods. Overall, the combination of fluorescent staining combined with the Minifiler amplification kit provided the best results for autosomal markers, whereas the Y‐Filer kit returned the expected results regardless of the used method.     

Y-STRs in forensic medicine: DNA analysis in semen samples of azoospermic individuals

ABSTRACT: The incidence of rape has increased, especially in metropolitan areas, such as the city of São Paulo. In Brazil, studies about it have shown that the majority of this type of crime is committed by the relatives and persons close to the victim. This has made the crime more difficult to be denounced, as only 10% of the cases are reported to competent police authorities. Usually, cytological exams are carried out in sex crime investigations. The difficulty in showing the presence of spermatozoa is frequent, but it does not exclude the presence of male DNA. The absence of spermatozoa in material collected from rape victims can be due to several factors, including the fact that the agressor suffers from azoospermia. This condition can be the result of a successful vasectomy. As the majority of DNA in the ejaculation sample is from spermatozoa, there is much less DNA to be analyzed. This study presents the application of Y‐STRs (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, and DYS393) in DNA analysis of sperm samples from 105 vasectomized men. The study demonstrated a great variation in DNA concentration. DNA extraction and amplification was possible in all sperm samples even in the absence of spermatozoa. The same profile was observed, for each individual, from DNA extracted from blood, pre‐ and postvasectomy semen samples. The use of markers specific for Y chromosome in sex crime cases, especially in the absence of spermatozoa, is very important, mainly because in most situations there is a small quantity of the agressor's DNA in the medium and a large quantity of the victim's DNA.     

Validation of a method to detect cocaine and its metabolites in nails by gas chromatography-mass spectrometry

The objective of the present work was to compare previously published methods and provide validation data to detect simultaneously cocaine (COC), benzoylecgonine (BE) and norcocaine (NCOC) in nail. Finger and toenail samples (5mg) were cut in very small pieces and submitted to an initial procedure for external decontamination. Methanol (3 ml) was used to release analytes from the matrix. A cleanup step was performed simultaneously by solid-phase extraction (SPE) and the residue was derivatized with pentafluoropropionic anhydride/pentafluoropropanol (PFPA/PFP). Gas chromatography-mass spectrometry (GC-MS) was used to detect the analytes in selected ion monitoring mode (SIM). Confidence parameters of validation of the method were: recovery, intra- and inter-assay precision, as well as limit of detection (LOD) of the analytes. The limits of detection were: 3.5 ng/mg for NCOC and 3.0 ng/mg for COC and BE. Good intra-assay precision was observed for all detected substances (coefficient of variation (CV)<11%). The inter-assay precision for norcocaine and benzoylecgonine were <4%. For intra- and inter-assay precision deuterated internal standards were used. Toenail and fingernail samples from eight declared cocaine users were submitted to the validated method.     

Shared services in Brazilian local government: Urban development in small counties

In this article we break new ground by investigating cooperative agreements in urban development services, which include urban development, housing and sanitation for small local governments in Brazil (i.e., those with fewer than 20,000 residents in 2013–15). We find that public expenditure on urban development can be explained by both horizontal (intermunicipal cooperation) and vertical (public–public partnerships) cooperation. Regarding the impact of public sector cooperation on public expenditure, our results show that housing and sanitation services are less costly under intermunicipal cooperation. By contrast, urban development services are less costly when local authorities do not cooperate with other public entities. For public–public partnerships (with the state or federal government) cooperation leads to an increase in public funding, which implies that cooperative agreements might not lead to lower public expenditure. The findings in this article provide useful empirical insights into the administrative reorganization of Brazilian local government.     

When Will a Victim Be Secondarily Victimized? The Effect of Observer's Belief in a Just World,Victim's Innocence and Persistence of Suffering

According to the belief in a just world (BJW) theory, the most threatening victim for the observers' BJW is the innocent victim whose suffering persists. Consequently the innocent victim whose suffering persists should be more secondarily victimized by high-BJW participants than by low-BJW participants. However, research has never systematically tested this basic prediction of the theory. In these two studies we tried to determine the impact of the observer's BJW, the victim's innocence, and the persistence of the victim's suffering on secondary victimization. In study 1, an interaction between BJW and victim's innocence was found on the attractiveness of the victim. In study 2, an interaction between BJW, victim's innocence, and persistence of suffering was found on the derogation of the victim.     

The International Monetary Fund,Party System Institutionalization,and Protest in Latin America

Extant studies have documented a positive correlation between country participation in International Monetary Fund–sponsored programs and collective protests in Latin America. However, anecdotal evidence indicates that there is a great deal of variation in the number of protests in recipient countries across the region. This article provides a theoretical argument that explains how the fund interacts with the level of party system institutionalization to affect the level of protest. The main prediction is that the level of protest decreases in recipient countries when the level of party system institutionalization is high. Empirical results from a sample of 16 Latin American democracies observed from 1982 to 2007 provide strong statistical and substantive support for the main hypothesis.     

Assessing the Reliability of Retrospective Reports of Adverse Childhood Experiences among Adolescents with Documented Childhood Maltreatment

The literature suggests that childhood maltreatment is related to a higher probability of developing psychopathology and disease in adulthood. However, some authors have questioned the reliability of self-reports of maltreatment, suggesting that psychopathology at the time of evaluation affects self-reports. We evaluated the reliability of the self-reports of 79 young adults who were identified in childhood by Child Protective Services by comparing two moments of evaluation. Psychological and physical symptoms were tested to evaluate their interference with the reports. We found good to excellent agreement, with no significant correlation between the changes in self-reported experiences and the changes in physical and psychological symptoms, suggesting that the reliability of reports is not related to the health state at the time of the report.
