Thin layer chromatography/fluorescence detection of 3,4-methylenedioxy-methamphetamine and related compounds

A rapid and sensitive method for the detection of six methylenedioxylatedphenethylamines, 3,4-methylenedioxymethamphetamine (MDMA); 3,4-methylenedioxyamphetamine; 3,4-methylenedioxyethylamphetamine; N-methyl-1-(3,4-methylenedioxyphenyl)-2-butamine; N-methyl-1-(3,4-methylenedioxyphenyl)-3-butamine; and 3,4-methylenedioxydimethylamphetamine, by thin-layer chromatography with fluorescence detection is proposed. These compounds form fluorophores on the developing plate following spraying with a reagent consisting of sodium hypochlorite, potassium hexacyanoferrate (III), and sodium hydroxide, and heating for 3 min at 100 degrees C. Blue fluorescent spots were observed under ultraviolet light in a wavelength range of 250-400 nm. The detection limits for MDMA and the above related compounds were 50 ng. The proposed method was effectively applied to the detection of MDMA in urine samples.     

从Gubisch案看欧共体法院对国际诉讼竞合的认定

国际诉讼竞合的认定是解决国际民商事管辖权冲突的先决条件。通过对欧共体法院一则判例的分析,指出,欧共体法院对国际诉讼竞合的认定趋向于持宽松的态度,而且,这种宽松的认定方法已被目前的国际立法和司法判例所吸收和支持。     

Application of DNA Forensic Techniques for Identifying Poached Guanacos (Lama guanicoe) in Chilean Patagonia*

Abstract: Guanaco (Lama guanicoe) is a protected and widely distributed ungulate in South America. A poacher, after killing guanacos in Valle Chacabuco, Chilean Patagonia, transported and stored the meat. Samples were retrieved by local police but the suspect argued that the meat was from a horse. Mitochondrial cytochrome b gene (774 pb), 15 loci microsatellites, and SRY gene were used to identify the species, number of animals and their population origin, and the sex of the animals, respectively. Analysis revealed that the samples came from a female (absence of SRY gene) Patagonian guanaco (assignment probability between 0.0075 and 0.0282), and clearly distinguishing it from sympatric ungulates (E‐value = 0). Based on the evidence obtained in the field in addition to forensic data, the suspect was convicted of poaching and illegally carrying fire arms. This is the first report of molecular tools being used in forensic investigations of Chilean wildlife indicating its promising future application in guanaco management and conservation.     

Abolishing Marriage: Can Civil Partnership Cover it?

This paper argues that all adult intimate relationships should be regulated under one single statute. This statute should be the Civil Partnership Act 2004 (which currently applies to same sex couples). The Matrimonial Causes Act 1973 (which applies to opposite sex couples), should be repealed; it should not be amended to include same sex couples. There would, as a consequence, be no such thing as (legal) marriage. Marriage as a legal construct is a heterosexual and patriarchal institution and is therefore so fundamentally flawed it is beyond the possibility of successful reform or repair. The present system of having two distinct legal means of relationship recognition is akin to sexual apartheid and is therefore unsustainable in the long term. Having a legal system which recognises only one form of legal partnership would therefore formally end a discriminatory system. Despite its drawbacks, Civil Partnership does not have the same extent of symbolic and practical degree of flaws as Marriage.

Female Sex Offenders: A Controlled Comparison of Offender and Victim/Crime Characteristics

The current study was a chart review of 31 female sex offenders (FSO), 31 male sex offenders (MSO), 31 female violent offenders (FO), and 31 male violent offenders (MO) using a 2 (female or male) by 2 (sex or violent offender) design. This is the first known study to employ three control groups when researching female sex offenders. Multiple variables appeared related to gender and crime. However, some variables emerged as FSO specific. They reported the least alcohol abuse history and had fewer admissions of guilt to the crime than the two violent offender samples. More FSOs knew their victim and were biologically related to their victim than MSOs. Lastly, the FSO sample was the least discriminating as to their victim’s gender and had the highest overall rate of sexual victimization.     

STRUCTURAL FACTORS AND BLACK INTERRACIAL HOMICIDE: A NEW EXAMINATION OF THE CAUSAL PROCESS*

This study evaluates the assumption that deprivation among African Americans and racial inequality lead to black interracial homicide due to racial conflict and antagonism. Using refined race‐adjusted Supplemental Homicide Report data, Uniform Crime Report data and census data, we test an alternative hypothesis that draws on the macrostructural opportunity theory to assess and more accurately specify the relationship between structural characteristics and black interracial homicide. We find that first, the relationship between economic factors and black interracial homicide can be explained in large part by high rates of financially motivated crime such as robbery, and second, that economic factors are associated with financially motivated but not expressive black interracial killings. Analyses of black intraracial killings are performed for comparison purposes. Collectively, the findings suggest that conflict‐based explanations rooted in racial antagonism and frustration aggression may be premature.     

A Pimp's Game: A Rational Choice Approach to Understanding the Decisions of Sex Traffickers

We employ a rational choice framework to understand the conditions under which sex traffickers allow their victims access to telecommunications devices while under their control. We posit that sex traffickers are rational actors who make calculated decisions regarding whether to allow their victims access to the Internet and cell phones. We hypothesize that sex traffickers allow younger victims and those they did not defraud in the recruitment process greater access to telecommunications devices because these decisions maximize their payoffs with minimal risk. However, we hypothesize that younger victims’ access to telecommunications devices is conditional on whether they have been defrauded in recruitment. In order to test these hypotheses, we deployed a survey to 115 victims of sex trafficking in the United States to learn about how they were recruited by their sex trafficker and the level of access they had to technology while under their sex trafficker's control. We find support for all of our hypotheses. The results have serious implications for criminal justice policy and practice.     

Fathers as carers in UK law and policy: dominant ideologies and lived experience

This article explores how working fathers are conceptualised within the UK’s work-family law and policy framework and whether a dominant ideology of fatherhood can be discerned. The socio-legal literature on men and masculinities is considered alongside established feminist theory on families, paid work and unpaid care to provide a backdrop to the analysis of current policy provision in this area. Three ‘ideal’ type ideologies of fatherhood are identified (‘absent’, ‘involved’ and ‘active’) which are used to critically examine the current legal framework. Despite claims to the contrary, the current framework supports and reaffirms the gendering of care so that the intransigence on the part of men and women to rebalance related responsibilities is unsurprising. The authors argue for a more care-centric approach to work-family policy in place of gender-specific normative modelling. A legal framework which enabled and encouraged all care providers to participate regardless of gender and biological relationship would not only improve the workplace experiences of women, but also enable men to develop and fulfil their care-giving aspirations and potential.
