Allelic frequencies of 48 informative insert-delete (INDEL) loci were obtained from a sample set of 130 unrelated individuals living in Macapá, a city located in the northern Amazon region, in Brazil. The values of heterozygosity (H), polymorphic information content (PIC), power of discrimination (PD), power of exclusion (PE), matching probability (MP) and typical paternity index (TPI) were calculated and showed the forensic efficiency of these genetic markers. Based on the allele frequency obtained for the population of Macapá, we estimated an interethnic admixture for the three parental groups (European, Native American and African) of, respectively, 50%, 21% and 29%. Comparing these allele frequencies with those of other Brazilian populations and the parental populations, statistically significant distances were found. The interpopulation genetic distance (FST coefficients) to the present database ranged from FST = 0.0431 (p < 0.00001) between Macapá and Belém to FST = 0.266 (p < 0.00001) between Macapá and the Native American group. 相似文献

A comparative morphological study of preimaginal stages (larvae and pupae) of Calliphora vicina Robineau-Desvoidy, 1830 is presented. The entomological samples came from laboratory colonies bred under controlled environmental conditions (25°C and 60% relative humidity). In this study, a recently published technique to clear Diptera larvae for light microscopy and a standard protocol for scanning electron microscopy were used. For the morphological comparison of larval instars I, II and III, and pupae of C. vicina, different larval regions (cephalic, thoracic and abdominal, including anal division), as well the internal chitinised cephalopharyngeal skeleton, were considered separately. Our results focus on showing the changes observed throughout development for the most important structures in the cephalic region (sensilla of maxillary palpus, antennae and oral ridges), the thoracic region (the first segment and its anterior spinose band) and in the anal division of the abdominal region (posterior spiracles and shape of the papillae). In addition, some morphological structures are described or pictured for the first time, such as the ventral organ and the anterior spiracle of larva I and the antenna sensilla, Keilin's organ and wrinkled area of the anal division of all instars. The cephalopharyngeal skeleton is an important structure for the taxonomy of Diptera larvae in all instars, including Calliphoridae. Our observations in C. vicina indicate that an in-depth review of the sclerite composition is needed. Pupae and larvae stages can only be compared by following the segmentary spinose bands and the anal segment, where the morphology of the posterior spiracles and papillae can be observed, in some cases despite the reduced condition of the latter. 相似文献

The comitology regime, the committee‐based system developed as a mechanism for controlling the Commission's exercise of its powers to implement EU measures, has been subject to severe criticism on grounds of lack of accountability and transparency. The system has recently been fundamentally reformed by means of the new Implementing Acts Regulation, which came into force on 1 March 2011. This paper investigates whether the new rules are sufficient to remedy accountability deficits as regards implementing acts and concludes that as far as accountability to the Member States is concerned, their control powers have remained static. In addition, the new‐delegated acts procedure introduced by the Treaty of Lisbon grants the European Parliament (EP) more control powers, although the EP's gains are more modest than they might appear. This change has come at the cost of reduced control powers for Member States as well as lowered standards of transparency for the public. 相似文献

Abstract: Crystal violet is a very common dye in ballpoint ink. Recent research suggests that the degradation of triarylmethane dyes gives an indication of the age of a ballpoint pen entry on a document. The main problem for the quantitative evaluation of the degradation is that it is highly dependent on the exposure to light. Moreover additional factors, such as additives and substrate play an important role in this process. The aim of this work is to compare the degradation pathways of the pure dye in water and ethanol upon exposure to xenon light by UV/VIS spectrophotometry and laser desorption ionization. Significant differences have been observed in the products and the kinetics of the degradation. N-demethylation, an expected decomposition process, was found to take place only in aqueous solution and kinetics calculations showed that the degradation occurred 2.5 times faster in ethanol compared to water. The degradation of crystal violet in inks from four ballpoint pens on paper was also studied for entries made over 2–3 years. It was observed that degradation reactions were quenched by the presence of another dye due to competitive absorption. It was also observed that the thickness of a stroke (concentration of ink) influenced the degradation process. In the absence of light only one ballpoint pen showed slight degradation. A better understanding of the influence of the paper, ink composition, and storage conditions is necessary to interpret correctly the age of an ink based on the degradation of dyes. 相似文献

This paper investigates the reform of public accounting in Portugal through the IPSAS adoption highlighting the perception of different stakeholders. Two competing theories (NPM and the institutional theory) are used to understand public accounting changes within the Portuguese context. In general, different stakeholders agree with the favorable moment and the context of the reform. The context of financial crises and the great external pressures to cut public deficits and to improve the quality of financial information seem to be the most important factors to stimulate changes in public accounting. In addition, stakeholders recommend the use of different strategies to ensure success. 相似文献

In this paper, we test the effect of three different criminal deterrence theory policy tools: criminal certainty, severity,
and celerity of punishment. Whereas most criminal deterrence studies in this field focus on the former two components of deterrence
theory, this study also examines the potential deterrent effect of the latter component. Using a time-series design with monthly
data, we estimate the effects of an increase in the threat of punishment for traffic offenses resulting from a general increase
in fines for traffic offenses, an increase in the probability of getting caught with a blood-alcohol concentration (BAC) level
outside the legal limits, and the enactment of an “on-the-spot” fine payment policy in Portugal. We find strong evidence to
support a severity effect. An increase in the statutory severity of sentence maxima for traffic violations leads to a decrease
in accident and injury rates—approximately an average 0.5 percent reduction in monthly accident and injury rates. Changes
in the BAC levels and the mandatory swift payment policy did not produce any convincing deterrence impact.

A part of a decomposed human body from an individual was found at his home, together with the decomposed bodies of his 3 dogs. The disappearance of half of the human body was hardly explained. Hypothetically the dogs, starving, could have eaten their owner after his death. All the bodies were recovered for autopsy.Small bone fragments were recovered in one dog's stomach and identified as human by anthropological analysis. DNA was extracted and cytochrome b gene analysis was made in order to determine their origin, confirmed as human.Genetic identification allowed achieving an eight mini-STR profile with MiniFiler (Applied Biosystems) identical to the bone material collected at the victim's autopsy, confirmed that the dogs had effectively eaten their owner.The results showed that it is possible to obtain nuclear DNA in samples subjected to gastric acids and the combination of different techniques allowed us to determine, in each step, the most convenient workflow for the remains identification. 相似文献
