Multicriteria Decision Aid to support Multilateral Environmental Agreements in assessing international forestry projects

The three Rio Conventions—the United Nations Framework Convention on Climate Change, the Convention on Biological Diversity, and the United Nations Convention to Combat Desertification—face the challenge to create synergies at different levels. The objective of this article is to describe how we have assessed synergies between the Rio Conventions at the project level in the forest sector. Since the complexity of the decision problem is high, we adopted the Multicriteria Decision Aid approach, which can provide a broad insight into the decision problem and find a compromise solution to a problem with multidimensional and conflicting criteria including social, economic and environmental features. The ELECTRE TRI model was used for assessing synergies at the project level, and has been a useful tool to quantify the performance of afforestation and reforestation projects into three categories (synergistic, reasonably synergistic, and not synergistic). For the first time, afforestation and reforestation projects have been assessed in a comprehensive way through decision criteria that reflect global and local interests using a non-compensatory multicriteria method.     

Cycles in Politics: Wavelet Analysis of Political Time Series

Spectral analysis and ARMA models have been the most common weapons of choice for the detection of cycles in political time series. Controversies about cycles, however, tend to revolve around an issue that both techniques are badly equipped to address: the possibility of irregular cycles without fixed periodicity throughout the entire time series. This has led to two main consequences. On the one hand, proponents of cyclical theories have often dismissed established statistical techniques. On the other hand, proponents of established techniques have dismissed the possibility of cycles without fixed periodicity. Wavelets allow the detection of transient and coexisting cycles and structural breaks in periodicity. In this article, we present the tools of wavelet analysis and apply them to the study of two lingering puzzles in the political science literature: the existence of cycles in election returns in the United States and in the severity of major power wars.     

Analyzing Brazilian vehicle documents for authenticity by easy ambient sonic-spray ionization mass spectrometry

Using desorption/ionization techniques such as easy ambient sonic-spray ionization mass spectrometry (EASI-MS), it is possible to analyze documents of Brazilian vehicles for authenticity, providing a chemical profile directly from the surface of each document. A method for the detection of counterfeit documents is described, and the falsification procedure is elucidated. Forty authentic and counterfeit documents were analyzed by both positive and negative ion modes, EASI(±)-MS. EASI(+)-MS results identified the presence of (bis(2-ethylhexyl)phthalate plasticizer and of dihexadecyldimethylammonium biocide in both types of documents. For EASI(-)-MS results, the 4-octyloxybenzoic acid additive ([M + H](+): m/z 249) is present only in counterfeit documents. It was also found that counterfeit vehicle documents are produced via Laserjet printers. Desorption/ionization techniques, such as EASI-MS, offer therefore, an intelligent way to characterize the counterfeiting method.     

Permanent teeth development in a Spanish sample. Application to dental age estimation

The purpose of this study is to clarify the chronology of different stages of dental development, according to Demirjian, in a sample of Spanish children, which will enable us to build a database that will be used as a reference in regard to the dental development of individuals of our socio-geographic environment. In the same studied sample, a calculation of the dental age according to Demirjian was carried out. This study was conducted in a final sample consisting of 1010 orthopantograms, corresponding to Spanish children (485 boys and 525 girls) ages 2-16. Comparing the age of onset of the different stages among the children, evidence was found that girls had an earlier general development than boys. These differences were only statistically significant in teeth and concrete stages. The canine teeth revealed greater gender dimorphism, with significant differences in all stages compared with the upper canines. The method proposed by Demirjian for dental age calculation resulted in a significant overestimation of dental age in relation to the chronological age in boys (average of 0.87 years) and girls (average of 0.55 years). Data from this study may be used as reference for dental maturity, as well as a standard for estimating age in Spanish children.     

Identification of gunshot residues in fabric targets using sector field inductively coupled plasma mass spectrometry technique and ternary graphs

During criminal investigations involving firearms, the detection of gunshot residues (GSRs) is one of the most important evidences. In the present study, a new method to identify trace evidences of GSRs, deposited around the bullet entrance hole, in different types of fabrics used as targets, is described. The experiments were carried out using a 0.38-inch caliber revolver, and 9-mm and 0.40-inch caliber pistols. Testimonies of 2.25 cm(2) of the fabrics were cut around the bullet entrance and digested with 10% nitric acid. Antimony, barium, and lead were analyzed in the remaining solution using a sector field inductively coupled plasma mass spectrometer. The concentrations of the elements were detected at levels up to few microgram per square centimeter. The use of ternary graphics allowed us to identify specific patterns of distribution for blank samples and the clear distinction between the revolver and pistols used.     

Identification and synthesis of by-products found in 4-methylthioamphetamine (4-MTA) produced by the Leuckart method

The synthesis of the designer drug 4-methylthioamphetamine (4-MTA) has been carried out using the well-known Leuckart reaction in four versions. The treatment of 4-methylthiophenylacetone with formamide, mixture of formamide/formic acid, ammonium formate, and mixture of ammonium formate and formic acid followed by acid hydrolysis brought about the formation of 4-MTA contaminated with a number of impurities. The gas chromatography mass-spectrometry (GC-MS) analysis of the reaction mixtures allowed identification of the most prominent impurities, such as diasteromers of N,N-di-[β-(4-methylthiophenyl)isopropyl]amine, N,N-di-[β-(4-methylthiophenyl)isopropyl]methylamine, N,N-di-[β-(4-methylthiophenyl)isopropyl]formamide, the Schiff bases derived from 4-MTA and 4-methylbenzaldehyde (benzaldimine) and 4-methylthiophenylacetone (ketimine) as well as some heterocycles: 4-methyl-5-(4'-methylthiophenyl)pyrimidine, 4-(4'-methylthiobenzyl)pyrimidine, 2,6-dimethyl-3,5-di-(4'-methylthiophenyl)pyridine, 2,4-dimethyl-3,5-di-(4'-methylthiophenyl)pyridine. The correctness of identification was confirmed by independent synthesis of these compounds. Each synthesized reference compound was characterized by means of MS, (1)H and (13)C NMR, and IR methods. The stereochemistry of (RR/SS) diasteromer of N,N-di-[β-(4-methylthiophenyl)isopropyl]amine was confirmed by a crystallographic method.     

A mixed methods study of participant reaction to domestic violence research in Jordan

Research on domestic violence against women has increased considerably over the past few decades. Most participants in such studies find the exercise worthwhile and of greater benefit than emotional cost; however, systematic examination of participant reaction to research on violence is considerably lacking, especially in the Middle East region. This study begins to fill this gap by examining women's reactions to domestic violence research in Jordan and whether a personal history of violence is associated with unfavorable experiences. This sequential exploratory mixed methods study included 17 focus group discussions (FGD) with women in Amman followed by a survey conducted in reproductive health clinics throughout the country (pilot n = 30; survey n = 517). Open coding was used to identify the theme related to participant reaction in the FGD data. This construct was further examined by the subsequent survey that included dichotomous questions inquiring whether the respondent thought the study questions were important and whether they were angry or felt resentment as a result of the survey. One open-ended question on the survey provided additional qualitative data on the theme that was combined with the FGD data. Themes identified in the qualitative data pertained to expressions of gratitude and comments on the survey's value. Findings of this study indicate that Jordanian women's responses to the research process are similar to women currently represented by the extant literature in that a vast majority of its participants felt that the study was important (95%) and it did not evoke anger or resentment (96%). Many even found the study to be useful to them personally or to society. Among those who had a negative emotional reaction, most still found the research to be important. This study's findings highlight the safety and potential benefits of ethically conducted violence research.     

Independent Discretion or Democratic Legitimisation? The Relations between National Regulatory Authorities and National Parliaments under EU Regulatory Framework for Network‐Bound Sectors

The European legislator, being supported in that regard by the Court of Justice, confers upon national regulatory authorities (NRAs) the exercise of the most important tasks concerned with the regulation of the network‐bound sectors, while at the same time guarantees NRAs a far‐reaching independence in exercising of their discretionary powers and shielding NRAs against other public authorities, including national parliaments. This, in turn, raises many doubts from the perspective of some essential constitutional principles of the Member States, such as, among others, ‘the domain of the law,’ which reserves the regulation of issues sensitive to the citizens as an exclusive parliament's prerogative. It is submitted in this article that national parliaments should play a much more active role in regulating the network‐bound sectors. The main point is to strengthen the protection of fundamental rights of regulated parties and create the real democratic legitimisation of NRAs, while not undermining those regulatory objectives that are already accorded at the EU level.     

DNA Commission of the International Society of Forensic Genetics (ISFG): an update of the recommendations on the use of Y-STRs in forensic analysis

The DNA Commission of the International Society of Forensic Genetics (ISFG) regularly publishes guidelines and recommendations concerning the application of DNA polymorphisms to the problems of human identification. A previous recommendation published in 2001 has already addressed Y-chromosome polymorphisms, with particular emphasis on short tandem repeats (STRs). Since then, the use of Y-STRs has become very popular, and a numerous new loci have been introduced. The current recommendations address important aspects to clarify problems regarding the nomenclature, the definition of loci and alleles, population genetics and reporting methods.     

Data for Y-chromosome haplotypes defined by 17 STRs (AmpFLSTR Yfiler) in two Tunisian Berber communities

The 17 Y-chromosomal short tandem repeats (STRs) included in the AmpFLSTR Yfiler PCR Amplification Kit (AB Applied Biosystems) (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 and GATA H4) were typed in two Berber communities, a small village (Takrouna) and a town (Sejenane), from North Tunisia. As expected, diversity was higher in the town, even when compared with a pool of three small Berber communities, probably due to the combination of different founder effects and genetic drifts operating in the small villages.
