Determination of nimetazepam and 7-aminonimetazepam in human urine by using liquid chromatography–tandem mass spectrometry

We report determination of metabolites of popular drugs of abuse, including nimetazepam and nitrazepam, in urine by using liquid chromatography/mass spectrometry. Nimetazepam and its metabolites, 7-aminonimetazepam and nitrazepam, were extracted by solid-phase extraction using a DAU cartridge. An ammonium acetate buffer solution (pH 4) and a Luna polar-RP column were selected as the mobile and stationary phase, respectively, for liquid chromatography. Mass spectrometry was used for analysis and was optimized for operation in the positive mode for all analytes. The urine specimens were screened for the presence of nimetazepam and its metabolites nitrazepam and 7-aminonimetazepam at a concentration of 0.1 ng/mL. Presence of 7-aminonimetazepam in the urine was an indicator of the subject being a probable abuser of nimetazepam.     

The impact of parental homeownership on children's outcomes during early adulthood

Abstract

Whether children benefit from being raised in a home owned by their parents has important policy implications and has been the topic of much scholarly debate. We match Panel Study of Income Dynamics data with census tract data to examine the impact of childhood experiences on adult outcomes for children followed over three decades. This allows us to document a wide range of characteristics.

For children born between 1968 and 1974, we analyze data on their first 18 years and also various outcomes when they are between 25 and 31 in 1999. We control for a comprehensive set of observable parental characteristics and develop a method to control for unobservable child characteristics together with an instrumental variable for the remaining selection problems. Parental homeownership status and children's college education and home‐ownership status are closely related, although the former is generated partially by the greater residential stability associated with homeownership.

How Linguistically Divided Media Represent Linguistically Divisive Issues. Belgian TV-Debates on Brussels-Halle-Vilvoorde.

In line with public sphere theory, media in federal political systems can be expected to provide a forum for federal debate on federal issues. However, as media in Belgium are organized at the level of the language communities this is not necessarily the case. This contribution analyses how political TV debates of the two public broadcasters in Belgium represented the issue of the split of the electoral district ‘Brussels–Halle-Vilvoorde’ (BHV), on which politicians of both language communities were divided. Results show that Dutch-speaking and French-speaking media in Belgium do not serve as a platform for federal debate where the contrasting viewpoints can be expressed, but rather echo and amplify the political consensus of their own language community.     

Planning Ahead? An Exploratory Study of South Korean Investigators’ Beliefs About Their Planning for Investigative Interviews of Suspects

Preparation and planning has been argued to be vitally important as to how effectively investigators undertake their interviews with suspects. Yet, it has also been found in previous research that investigators admit that they plan only occasionally, often attributing insufficient time as a reason for not undertaking the task. Employing a novel research paradigm that utilised theoretical foundations concerning planning, the present study explored empirically 95 South Korean financial crime investigators’ views, using a self-administered questionnaire. With the use of second-generation statistical modelling, an understanding was developed of the relative relationships between various concepts (which had themselves emerged from an established theoretical framework of planning that had been further extended to accommodate the context of the present study). The study found that perceived time pressures actually showed a very low association with interview planning. Rather, investigators’ self-belief as to their own capability alongside workplace culture was each found to have stronger associations with investigators’ intentions to plan for their interviews. As such, we argue that there should be more focus on improving occupational culture relating to interview planning, while developing training programs that identify, evaluate, and enhance investigators’ planning skills. Implications for practice are therefore discussed.     

The Patterns of Masculinity in Prison

A prison culture of masculinity shapes the prison macho – boys dont cry. The prison macho is a real man who always hides his feelings and performs like a tough guy. These characteristics are much different from what happens in everyday life in the social spheres, where human being needs to be loved, need concerns and compassion from others and express these to others as well. In the current study, there is a recognition of a multiplicity of masculinities and an emphasis on how subjects are continually constituting and constructing their identity. Based on qualitative research, this study analyzes the patterns of masculinity embedded in the daily code of conduct used by prison staff to deal with prisoners and by prisoners to interact with other inmates and constitute their subculture. The investigation of prison sociology in the constitution of masculinity discourses in Tainan Prison contributes to both gender studies and to the literature exploring differences between western and eastern perspectives and policies related to incarceration.     

DNA analysis of digested tomato seeds in stomach contents

Examination of stomach contents is one of the important steps in medical legal autopsy. Vegetative materials such as stems, roots, and seeds in stomach contents can be valuable evidence for providing investigative leads in death investigation. Currently, the identification of plant materials relies on microscopic and morphologic examination. We have found that many seeds are often protected from acid degradation during stomach digestion by their tough exterior seed coat. Tomato seeds were selected as a model system to assess DNA analysis and plant variety marker identification. The DNA-amplified fragment length polymorphism method was performed to determine if the DNA obtained from single seeds could be used for PCR analysis. From the amplified fragment length polymorphism results, some candidate markers for individualizing seeds from morphologically distinct tomatoes were identified. These data on DNA analysis of tomato seeds indicate amplified fragment length polymorphism is a viable procedure for the individualization of seeds from stomach contents in forensic investigations.
