Anise oil as para-methoxyamphetamine (PMA) precursor

These days, MDMA is one of the most popular drugs of abuse. Due to its illegality, MDMA and its chemical precursors are watched by governmental organizations in many countries. To avoid conflicts with legal instances, underground chemists have tried to market several new unregulated amphetamine analogues, such as 4-MTA. Para-methoxyamphetamine (PMA), on the other hand, is regulated by law but its precursors are easily obtained since they are cheap and unwatched. This article presents such a case, namely the large scale synthesis of PMA using anethole, a main constituent of anise oil, as precursor. Anethole has been converted to its phenyl acetone analogue via peracid oxidation, while PMA itself has been synthesized using this ketone as precursor in the Leuckart synthesis. The synthesis of PMA using anethole as starting product has been investigated applying GC/MS and GC-HSPME/MS techniques, hereby discovering new specific (4-methoxyphenol) and already identified synthesis impurities (4-methyl-5-(4-methoxyphenyl)pyrimidine, N-(beta-4-methoxyphenylisopropyl)-4-methoxybenzyl methyl ketimine, 1-(4-methoxyphenyl)-N-(2-(4-methoxyphenyl)-1-methylethyl-2-propanamine, 1-(4-methoxyphenyl)-N-methyl-N-(2-(4-methoxyphenyl)-1-methylethyl-2-propanamine, N-(beta-4-methoxyphenylisopropyl)-4-methoxybenzaldimine). The new impurity 4-methoxyphenol is specific for the application of a peracid oxidation method where anethole is used as precursor.     

Genetic structure among 38 populations from the United States based on 11 U.S. core Y chromosome STRs

A DNA database consisting of the 11 Y chromosome short-tandem-repeat (Y-STR) recommended by the Scientific Working Group on DNA Analysis Methods is constructed for 2517 individuals from 38 populations in the United States. The population samples derive from five ethnic groups currently living in 10 states. A multidimensional scaling (MDS) plot places the populations into four discrete clusters (African Americans (AA), European Americans (EA), Hispanic Americans (HA), and Asian Americans (SA)) and one dispersed cluster of Native Americans. An analysis of molecular variance (AMOVA) indicates that a large proportion of the total genetic variance is partitioned among ethnic groups (24.8%), whereas only a small amount (1.5%) is found among-populations within ethnic groups. Separate AMOVA analyses within each ethnic group show that only the NA sample contains statistically significant among-population variation. Pair wise population differentiation tests do uncover heterogeneity among EA and among HA populations; however, this is due to only a single sample within each group. The analyses support the creation of AA, EA, HA, and Asian American databases in which samples from different geographic regions within the United States are pooled. We recommend that separate databases be constructed for different NA groups.     

An unusual form of fatal ethanol intoxication

Forensic pathologists are very familiar with deaths due to ethanol intoxication. The overwhelming majority of these deaths are a result of the oral ingestion of ethanol. We report an unusual case of an individual who expired in his secured residence after self administration of a wine enema. Toxicology showed an ethanol concentration of 0.40 g/dL in the blood and 0.41 g/dL in the vitreous fluid. Scene investigation was of paramount importance in determining the unusual method by which the decedent absorbed the alcoholic beverage.     

New directions in social stratification and income distribution: Introduction

The contributors to this special issue address important problems in the area of social stratification and income distribution. More specifically, Van der Sar and Van Praag offer a solution to the problem of measuring the relative importance of a social position by referring to the individual utility function. Hermkens and Boerman test hypotheses derived from functionalist and marxist theory concerning the degree of value consensus associated with the differential allotment of income and prestige to social positions. Shepelak points to the effects of a prevailing system of norms and values — beliefs about meritocracy, fair shares and opportunity — on the equalization of incomes. Arts and Van Wijck study social constraints to income equalization and focus on the inadequacy of decision-making processes and imperfect implementation of decisions. In the final contribution to this issue, Jasso examines the behavioral and social consequences of the simultaneous operation of two distinct considerations on courses of action: the individual's own well-being and the societal common good.     

Predictors of adult attitudes toward corporal punishment of children

This study identifies predictors of favorable attitudes toward spanking. Analyses were performed with survey data collected from a representative sample of 1,000 adults from Quebec, Canada. According to this survey, a majority of respondents endorsed spanking, despite their recognition of potential harm associated with corporal punishment (CP) of children. The prediction model of attitudes toward spanking included demographics, experiencing or witnessing various forms of family violence and abuse in childhood, and perceived frequency of physical injuries resulting from CP. Spanking was the most reported childhood experience (66.4%), and most violence and abuse predictors were significantly and positively correlated. Older respondents who were spanked in childhood and who believed that spanking never or seldom results in physical injuries were the most in favor of spanking. On the other hand, respondents who reported more severe physical violence or psychological abuse in childhood were less in favor of spanking. Findings are discussed in terms of prevention of CP and family coercion cycle.     

Introduction: market adaptations,interventions and daily experience

This special issue illuminates diverse realities of post-Soviet development in Central Asia through a multidisciplinary prism. The contributing articles are grounded in a range of social science disciplines including architecture, anthropology and geography, as well as drawing from mainstream social sciences. The analyses demonstrate how a synthesis of specialist knowledge from area studies and individual disciplinary methodologies can provide well-grounded critical positions on development.
