Soil vestiges might provide information about a crime scene. The Rietveld method with X‐ray diffraction data (RM‐XRD) is a nondestructive technique that makes it possible to characterize minerals present in the soils. Soil clays from the metropolitan region of Curitiba (Brazil) were submitted to DCB treatment and analyzed using XRD with CuKα radiation in the step‐scan mode (0.02° 2θ/5 s). The GSAS+EXPGUI software was used for RM refinement. The RM‐XRD results, together with the principal component analysis (PCA) (52.6% total variance), showed the kaolinite predominance in most analyzed samples and the highest quartz contents in “site 1.” Higher anatase, and gibbsite and muscovite contents influenced discrimination, mainly in “site 3” and “site 1,” respectively. These results were enough to discriminate clays of four sites and two horizons using a reduced amount of sample showing that the technique can be applied to the investigation into soil vestiges.  相似文献

Piracatinga (Callophysius macropterus) are a type of bottom feeder catfish encountered in the Amazon River and its tributaries. We report two cases in which human remains were first located based on a characteristic circular distortion of the surface of the river that the Piracatinga make while they feed. Human skin samples of one of the victims recovered from the Piracatinga digestive tract were subjected to mitochondrial DNA analysis that allowed identification of the body of Case 1; the family recognized body parts of Case 2. Importantly, the location of human body parts and their identification based on DNA analysis enabled the respective families to obtain a death certificate expeditiously in the absence of identifiable remains—a process that normally requires 5 years under current Brazilian law, and in the absence of closure, imposes severe emotional stress on the family of the deceased.  相似文献

This study investigates how an institutional exogenous change interacts with professional norms in relation to behavior in public organizations. We test how a new grading scale introduced in 2007 changed grade point averages and pass rates at two university departments. Data consist of register data on grading between 2004 and 2010. We find that the new grading scale both increased grade point averages and pass rates and halted the negative time trend in these variables. These effects are even greater for exams with an external examiner. The main conclusion is that grading systems affect grading both immediately and over time.  相似文献

ABSTRACT

The usefulness of performance indicators increases when organizations compare their data. However, most discussions have failed to emphasize two lines of action that could improve the relevance of such comparisons: a) agreement among service managers on the indicators to be used in the evaluation; b) homogenization of the indicators to be used by organizations, and of the process used to calculate them. In this context, this paper proposes a methodology based on the participation of and consensus among managers, which helps to standardize the construction and presentation of performance indicators. The aim of this proposal is to improve the comparative evaluation of organizations. Finally, in order to test the proposal, a practical application is carried out on the local culture departments of nine large municipalities in southern Spain.  相似文献

The Dutch practice of negotiated wage restraint and welfare state reform is often held up as a model for effective labour market adjustment. This article examines the distribution of adjustment costs under the Dutch model to determine whether it is stable in the long run ‐ both directly and by analogy with the situation in Belgium. The conclusion is that while the Dutch have succeeded in effecting a remarkable adjustment in the distribution of value‐added, the costs of this adjustment have been skewed against increasingly large sections of society. Should these groups outside the distributional coalition find representation at the national level, the Dutch model for negotiated wage restraint and welfare state reform is likely to revert to political alternation and tit‐for‐tat economic competition.  相似文献
