Normally, the identification of the LSD drug is performed by forensic laboratories, using the Ehrlich spot test. However, this is a nonspecific analysis. Additionally, the Brazilian Federal Police has identified the presence of a new compound in seized blotters: 9,10-dihydro-LSD, an uncontrolled substance. In this work, easy ambient sonic-spray ionization mass spectrometry in the positive ion mode, EASI(+)-MS, was used to characterize LSD and 9,10-dihydro-LSD compositions directly from the surface of blotters. The presence of LSD in the seized blotter samples were also confirmed via high-performance liquid chromatography with ultraviolet detector. In a set of 41 blotters analyzed by EASI(+)-MS, 28 showed positive results for LSD, seven for 9,10-dihydro-LSD, and another six samples showed negative results for both LSD and 9,10-dihydro-LSD. The combination of thin layer chromatography with EASI-MS also demonstrated to be a relatively simple and powerful screening tool for forensic analysis of street drugs.  相似文献

This correlational cross-sectional study was designed to investigate whether the intimate partner violence (IPV) suffered by mothers (physical and psychological maltreatment), the neglect suffered by children, and the maltreatment (physical and psychological) directly suffered by children are statistically associated with an increase in the probability of the child’s suffering psychopathological problems. The sample consisted of 189 Spanish children aged 6 to 17 and their mothers, recruited from Centers of Specialized Assistance for Women Victims of IPV. The results of a canonical correlation analysis showed that the most significant problems suffered by the children were both externalizing and internalizing ones. In girls, the maltreatment suffered by their mothers was directly related to a larger frequency of somatic complaints than in boys. In addition, physical maltreatment to the mother and emotional maltreatment suffered by the child exhibited a statistically significant relationship with aggressive behaviour, thought problems, rule-breaking behaviour, attention problems, and withdrawn-depressed.  相似文献

Based on the results of previous investigations, this study seeks for individual, relationship and community characteristics among women living with their partner associated with intimate partner violence [IPV] victimization. The sample of 19,131 women was taken from the 2016 Peru Demographic and Health Survey. A binomial logistic regression model showed among the most significant risk factors: heavy drinking by the woman’s partner (OR = 8.655, p < .001), having witnessed parental domestic violence (OR = 1.496, p < .001) and having experienced physical punishment during childhood (OR = 1.306, p < .001). Other factors related to higher odds of IPV at the individual level include employment and low educational attainment. Relationship risk factors comprise, 25 to 29 years of relationship duration, living in cohabitation, previous unions and low socioeconomic status. At the community level, living in an urban residence increases the likelihood of abuse. These findings highlight the need to include these factors, in the IPV prevention strategies.  相似文献

This article examines the factors that account for the Armed Forces of the Philippines's (AFP) never-ending involvement in many wars of the third kind. It discusses the essence of counter-insurgency warfare or low-intensity conflict in the Philippine setting. The article then notes that the disruption in the US military assistance after 1992, the AFP's inability to modernize, and its continuous campaign against communist and secessionist insurgents have adversely affected its structure and overall combat efficiency. It also analyzes the impact of the global war on terror on the Philippine military's counter-insurgency operations and the reforms undertaken by the Philippine defense establishment to address these issues. In conclusion, the article argues that reforms will not lead to a significant transformation of the AFP as it will continue to be an orphan of counter-insurgency in the near future. However, if wars of the third kind will persist, this situation will paradoxically make the AFP the only military in Southeast Asia aptly geared for the long war of this century.  相似文献

This article discusses the impact of drought on poverty dynamics in the South Wollo area of northeastern Ethiopia. Using both survey and anthropological/qualitative data covering a six-year period, the paper assesses which households were able to hold on to assets and recover from the 1999–2000 drought and which were not. It suggests that while the incidence of poverty changed very little during 1997 to 2003 despite the occurrence of a major drought, the fortunes of the poorest improved, but not enough to keep them from poverty. The study concludes by asking how current policies affect patterns of poverty and inequality and what might be done to improve welfare in South Wollo.  相似文献
