Determination of the active principles of Catha Edulis: quali-quantitative analysis of cathinone, cathine, and phenylpropanolamine

In the last years, all the vegetable material supposed to belong to the Catha Edulis species, seized at the Malpensa and Orio al Serio airports, were analyzed in our laboratory on behalf of the Tribunals of Busto Arsizio and Bergamo, respectively. After a preliminary botanic examination, the quali-quantitative determination of the active principles cathinone, cathine and phenylpropanolamine (PPA) was carried out by means of GC/MS and GC/FID techniques, which meet the requirements of the forensic analyses. We developed a fast, effective and reliable derivatization procedure which allowed to simultaneously detect cathine and PPA, whose discrimination is mandatory since PPA is not a psychoactive agent. Cathine was distributed in the various parts of the plant (leaves and stems) and its quantity ranged from 0.03% to 0.17% of the weight of the vegetable material; PPA was not detected in the twigs and its quantity in the leaves ranged from 0.07% to 0.16%. The quantitative determination of cathinone was carried out directly on the methanol solution after maceration of the vegetable material, its quantity ranging from 0.02% to 0.10%. No significant difference in the content of the two active principles was found between the fresh and the dried material.     

Alcohol-Related Mortality Risk in Natural and Non-Natural Death Cases

Abstract:  Determination of the associations between alcohol influence and sudden natural death represents challenges for medicolegal investigations. The aim of this study was to investigate the prevalence of alcohol influence in medicolegal autopsies. In our study of natural and non-natural deaths cases (5496 total: 4045 males, 1451 females) were examined. Blood alcohol concentrations (BACs) were detected by headspace gas chromatographic method. We investigated the alcohol-related mortality using hierarchical log-linear statistical models. Severe BACs were detected among suicidal victims in the oldest age group (>65 years) (In F  = 0.442) and among the homicide victims between the age of 40–65 years (In F  = 0.234). Correlations we found between manner-of-death and sex suggested that the rate of males in accidents (ln F  = 0.140) and the rate of females in homicides (ln F  = 0.193) were higher. It was concluded that the accurate statistical mortality database may provide a huge support for the determination of alcohol effects on human health and mortality.     

African-Caribbean women, (post)? Diaspora,and the meaning of home

ABSTRACT

Drawing on bell hooks, Audre Lorde and Carole Boyce-Davies, this paper develops an ethical framework to provide a gendered analysis of relative power inside and outside the home. In doing so, it considers the ways in which our view of home as African-Caribbean women, impacts our understanding of '(post) diaspora' (Dunn, Leith, and Suzanne Scafe. 2019. “African-Caribbean Women: Migration, Diaspora, Post-Diaspora.” Caribbean Review of Gender Studies 13: 1–16) in the UK. Insofar as home is central to the idea of diaspora, I suggest that home must be conceptualised as an interdependent 'adult's' home rather than a dependent 'child's' home. On this reading, in the context of global power relations, I caution that while offering a useful and necessary point of departure from diaspora, the use of 'post' could be deployed to undermine an unapologetically intersectional black politics. As such, I claim the (Post) Diaspora Network's methodology, rather than the term itself, best demonstrates the liberatory intent and importance of a (post) diaspora subjectivity.     

International Dimensions: What Is the Role of Third Parties?

In the Arab–Israeli arena, third parties have traditionally played a prominent role. External intervention has tended to peak when violence threatens international interests (e.g., the 1973 Arab–Israeli War), or when the parties are unable to sustain a negotiating process. Whether providing political and security assurances aimed at mitigating insecurity or offering economic inducements to underwrite peace accords, third parties have made a number of positive contributions toward managing the conflict.     

The evolution and current state of public affairs in Hungary

This paper discusses the recent developments in public affairs in Hungary from a historical perspective. The country's communist/socialist past and the relative novelty of the public affairs industry paint an interesting picture of the evolution and the direction of this field. The paper covers the political and economic processes starting from the transition period through recent events. Although there have been several promising developments in the area of public affairs and corporate lobbying during the last 20+ years, Hungary's increasingly anti-democratic policies, corruption scandals, and centralized decision-making processes have hindered the proper functioning of the public affairs profession and have limited the influence of corporations and interest groups in the country.

The relationship between socio-economic characteristics, victimization and CPTED principles: evidence from the MIMIC model

This study seeks to explore how different house type, socio-economic variables in the neighborhood (length of residence and household income) and residents’ victimization experience influence Crime Prevention through Environmental Design (CPTED) and its respective principles: natural surveillance, access control, territoriality and maintenance. The study focuses on a sample of 164 inhabitants from a typical neighborhood in the city of Penang, Malaysia. An observation checklist was used to measure all the four principles of CPTED. A Multiple Indicator-Multiple Cause (MIMIC) analysis using AMOS 16.0 was employed to analyze the data at the level of individual property. Each latent factor and the relationships among them were modeled in a priori MIMIC hypothesized model. Prior to the MIMIC analysis, the study employed first and second-order confirmatory factor analysis on CPTED to determine the best indicators for the CPTED construct. The findings confirmed that CPTED is best measured by four principles. The results further indicate that CPTED is associated with a reduced risk of burglary victimization, while household income is positively associated with CPTED. The model shows that territoriality has a negative direct relationship with victimization. There are direct and positive influences of house type on natural surveillance and territoriality, while the length of residence only affects access control.

Validation of a large Italian Database of 15 STR loci

Results from a collaborative exercise with proficiency testing conducted by 20 Italian laboratories on the 15 loci included in the Identifiler kit were analyzed by allele sharing methods and by standard population genetics tests. The validated database, including about 1500 subjects, was merged with that of a previous exercise conducted on nine loci, and the resulting allele frequencies, subdivided by Italian region, were published on-line.
