American elites' strategic thinking towards Korea: From Kennan to Brzezinski

America's foreign policy elites have made different assessments of South Korea's value as an alliance partner, largely depending on their strategic beliefs and visions. Balance-of-power realists like George Kennan have tended to let the regional problems be taken care of by the regional major powers, thus attaching less strategic value to such peripheral states as Korea. On the other hand, globalists like Paul Nitze have emphasized America's preponderant role in maintaining global stability, attaching greater importance to the US-Korean alliance. This article investigates the American foreign policy elites' strategic thinking toward Korea by reviewing the thoughts of Kennan, Nitze, Kissinger and Brzezinski. It then draws out implications for the future US defence commitment to Korea.     

Cannabis sales and immigrant youth gangs in Denmark – An exploratory study of market structure and youth gang evolution

Cannabis sales by youth gangs consisting of male descendants of immigrants from Middle Eastern countries are subject of much public debate in Denmark and Scandinavia. Only little research has explored the intersection between the wider social context of the drug market and the criminal engagements of these groups using qualitative methods. Using eleven semi-structured interviews with youth, police and experts, collected between 2011 and 2013, this study examines how the overall structure of the cannabis market in Copenhagen affects the opportunities to engage in cannabis sales for immigrant youth gangs. The study rests on an assumption that increased deterrence in specific geographic areas will displace buyers and shift market shares between competing groups. The result was that increased cannabis dealing furthered gang evolution even at the lowest organizational steps, from neighbourhood groups to more delinquent collectives. A key finding is that neighbourhood youth clubs play a central role in the lives of the interviewees. Youth clubs served as social spaces but also functioned as a form of turf to be conquered from city officials.     

Measuring Crime Concentration Across Cities of Varying Sizes: Complications Based on the Spatial and Temporal Scale Employed

Objectives

We argue that assessing the level of crime concentration across cities has four challenges: (1) how much variability should we expect to observe; (2) whether concentration should be measured across different types of macro units of different sizes; (3) a statistical challenge for measuring crime concentration; (4) the temporal assumption employed when measuring high crime locations.

Methods

We use data for 42 cities in southern California with at least 40,000 population to assess the level of crime concentration in them for five different Part 1 crimes and total Part 1 crimes over 2005–2012. We demonstrate that the traditional measure of crime concentration is confounded by crimes that may simply spatially locate due to random chance. We also use two measures employing different temporal assumptions: a historically adjusted crime concentration measure, and a temporally adjusted crime concentration measure (a novel approximate solution that is simple for researchers to implement).

Results

There is much variability in crime concentration over cities in the top 5 % of street segments. The standard deviation across cities over years for the temporally adjusted crime concentration measure is between 10 and 20 % across crime types (with the average range typically being about 15–90 %). The historically adjusted concentration has similar variability and typically ranges from about 35 to 100 %.

Conclusions

The study provides evidence of variability in the level of crime concentration across cities, but also raises important questions about the temporal scale when measuring this concentration. The results open an exciting new area of research exploring why levels of crime concentration may vary over cities? Either micro- or macro- theories may help researchers in exploring this new direction.

     

Debts and Threats: Managing Inability to Repay Credits in Illicit Drug Distribution

This study examines how creditors in illicit drug markets manage debtors’ inability to repay “fronted” drugs. Based on qualitative interviews with 40 incarcerated drug dealers in Norway, we explore four outcomes of unpaid drug debts. Two modes of governance dominated the credit reciprocation processes: Cooperative governance included strategies of accepting loss and refinancing debt and required mutual trust between creditor and debtor. Adversarial governance included extortion of debtors and revenge and was based on threats of violence. We found that creditors preferred refinancing debt or extorting debtors over accepting loss or using violence. We argue that the negotiated outcomes of drug debt have been neglected in research on drug markets, and explore how they require investment from the creditor, either in building trust or in deterring malfeasance through threats of violence. Using insights from economic sociology, the study highlights the importance of social control in illegal drug markets.     

Determination of amphetamine-type stimulants,ketamine and metabolites in fingernails by gas chromatography–mass spectrometry

A gas chromatography–mass spectrometry (GC–MS) method was developed and validated for the simultaneous qualification and quantification of methamphetamine (MA), amphetamine (AP), 3,4-methylenedioxy-N-methylamphetamine (MDMA), 3,4-methylenedioxy-N-amphetamine (MDA), ketamine (KET) and norketamine (NKT) in fingernails. Fingernail samples (20 mg) were washed with distilled water and methanol, digested with 1.0 M sodium hydroxide at 95 °C for 30 min, and then extracted with ethyl acetate. Extract solutions were evaporated to dryness, derivatized using heptafluorobutyric anhydride (HFBA) at 60 °C for 30 min, and analyzed by GC–MS. The linear ranges were 0.1–20.0 ng/mg for AP, MDMA and NKT, 0.2–20.0 ng/mg for MA and MDA, and 0.4–20.0 ng/mg for KET, with the coefficients of determination (r² ≥ 0.9989). The intra- and inter-day precisions were within 7.1% and 10.6%, respectively. The intra- and inter-day accuracies were ?10.9% to 0.8% and ?4.3% to 4.5%, respectively. The limits of detections (LODs) and the limits of quantifications (LOQs) for each analyte were lower than 0.094 ng/mg and 0.314 ng/mg, respectively. The recoveries were in the range of 72.3–94.9%. The average fingernail growth rates of two subjects for three years and six subjects for two months were 3.12 mm/month and 3.16 mm/month, respectively. The method proved to be suitable also for the simultaneous detection and quantification of MA, MDMA, KET and their metabolites in fingernails.     

DNA Typing for the Identification of Old Skeletal Remains from Korean War Victims*

Abstract: The identification of missing casualties of the Korean War (1950–1953) has been performed using mitochondrial DNA (mtDNA) profiles, but recent advances in DNA extraction techniques and approaches using smaller amplicons have significantly increased the possibility of obtaining DNA profiles from highly degraded skeletal remains. Therefore, 21 skeletal remains of Korean War victims and 24 samples from biological relatives of the supposed victims were selected based on circumstantial evidence and/or mtDNA‐matching results and were analyzed to confirm the alleged relationship. Cumulative likelihood ratios were obtained from autosomal short tandem repeat, Y‐chromosomal STR, and mtDNA‐genotyping results, and mainly confirmed the alleged relationship with values over 10⁵. The present analysis emphasizes the value of mini‐ and Y‐STR systems as well as an efficient DNA extraction method in DNA testing for the identification of old skeletal remains.     

Simple and highly effective DNA extraction methods from old skeletal remains using silica columns

The recovery of DNA data from old skeletal remains is often difficult due to degraded and very low yield of extracted DNA and the presence of PCR inhibitors. Herein, we compared several silica-based DNA extraction methods from artificially degraded DNA, DNA with PCR inhibitors and DNA from old skeletal remains using quantitative real-time PCR. We present a modified large-scale silica-based extraction combined with complete demineralization, that enables maximum DNA recovery and efficient elimination of PCR inhibitors. This is performed with high concentration of EDTA solution for demineralization of bone powder followed by QIAamp^® spin columns and buffers from the QIAquick^® PCR purification kit. We have successfully used this modified technique to perform STR analysis for 55-year-old skeletal remains. The results of this study will contribute to solve the forensic cases dealing with skeletal remains.     

Abused South Korean women: a comparison of those who do and those who do not resort to lethal violence

This study compares two groups of women in South Korea: one group incarcerated for the deaths of their male partners and the other staying in a shelter for battered women. The analysis serves to answer two questions: First, are the findings regarding women who kill their intimate partners in Western societies generally applicable to their counterparts in South Korea? Second, how are abused South Korean women who resort to lethal violence against their abusers different from those who do not? Regarding both abused and nonabused women incarcerated for criminal homicide against their partners, results indicate that they have less experience of psychological and physical abuse by their partners and that they are less educated, underemployed, and more supportive of traditional patriarchal norms than are the women who utilize domestic violence shelters. This research explores implications for intervention strategies to encourage abused women to seek help from legal and extralegal sources.
