Meanwhile,political scientists are also becoming more interested in theuse of multilevel models (MLM). However, little work existsto understand the benefits of multilevel modeling when appliedto TSCS data. We employ Monte Carlo simulations to benchmarkthe performance of a Bayesian multilevel model for TSCS data.We find that the MLM performs as well or better than other commonestimators for such data. Most importantly, the MLM is moregeneral and offers researchers additional advantages. Authors' note: A previous version of this article was presentedat the 2005 Midwest Political Science Meeting.

Free Fatty Acids Composition in Adipocere of the Kwäday Dän Ts’ìnchí Ancient Remains Found in a Glacier*

Abstract: Adipocere is a postmortem decomposition product consisting of mostly a mixture of free fatty acids (FFAs) that are formed because of the hydrolysis of triglycerides in adipose tissues. This article describes a simple and robust method for the extraction, identification, and quantification of FFA commonly found in adipocere using gas chromatography–mass spectrometry (GC/MS). This method was applied to analyze tissues from Kwäday Dän Ts’ìnchí, ancient remains discovered in a retreating glacier in the Tatshenshini‐Alsek Park, British Columbia, Canada in August 1999. The lyophilized tissues were grinded and extracted with hexane. The trimethylsilyl fatty acid derivatives were analyzed by GC/MS, and the relative abundances of myristic acid, palmitic acid, oleic acid, and stearic acid were determined. Milligram per gram levels of saturated fatty acids were found in the tissues of the ancient remains, while the levels of unsaturated fatty acids, such as palmitoleic acid, were found to be negligible. The results provided further evidence of the existence of adipocere found during forensic examination of the Kwäday Dän Ts’ìnchí ancient remains.     

区域经济发展的法制协调机制浅析

区域经济的协调发展需要有统一、完善的法制作保障。国家统一的法制往往满足不了特定区域经济协调发展的需求,而地方性法规和规章又只能在本行政区域内发生作用,且地方立法之间往往存在着冲突。借鉴美国的法制协调经验,构建我国的区域法制协调机制,有利于我国区域经济的协调发展。     

Isolation and characterisation of a novel sildenafil analogue adulterant,desmethylpiperazinyl propoxysildenafil,in a dietary supplement

A new sildenafil analogue was detected during routine screening of dietary supplements suspected to be adulterated with an erectile dysfunction drug(s) using HPLC-DAD. The UV spectrum of this compound was highly similar to that of sildenafil and almost identical to that of desmethylpiperazinyl sildenafil. The analogue was purified by using semi-preparative HPLC and structurally elucidated by performing mass spectrometric and NMR spectroscopic experiments. The spectral data revealed that this sildenafil analogue bears an n-propoxy group instead of an ethoxy group and possesses no methylpiperazinyl moiety. The isolated compound, structure of which was further confirmed by spectral comparison with synthetic one, was thus named as desmethylpiperazinyl propoxysildenafil.     

Fingermark visualisation on metal surfaces: An initial investigation of the influence of surface condition on process effectiveness

Fingermark recovery from metal surfaces is an area of operational interest, both from the association of metals with weapons used in violent crime and from the increasing incidence in metal theft. This paper reports a feasibility study into the effectiveness of a range of fingermark visualisation processes in developing fingermarks on clean metals (brass, bronze and stainless steel), and on the same metals after prolonged exposure to an outdoor environment. Scanning electron microscopy (SEM) was used to investigate how the surface type and condition could influence the development of fingermarks for each of the processes used. It was found that the behaviour observed varied between each of the processes (cyanoacrylate fuming, Lumicyano?, gun blueing and carbon-based powder suspension). In some cases the chemical composition of the surface affected the development of the mark more than the surface condition, and in other cases the reverse was true. The best performing processes differed according to the surface type and condition, with cyanoacrylate fuming processes working best on brass and bronze, and powder suspensions being better on stainless steel. These preliminary results reinforce the need to take into account both surface type and condition before selection of the most effective fingermark visualisation process and demonstrate the value of techniques such as SEM in developing a fundamental understanding of the interactions between fingermarks and surfaces.     

Community‐based restorative transitional justice in Sierra Leone

Community‐based restorative transitional justice is an important feature of peace consolidation, maximizing access to justice and facilitating reconciliation. Examining post‐conflict Sierra Leone as a case study, the author draws on existing justice practices in Sierra Leone as examples of restorative responses to war criminality. Specifically, the traditional reintegration of former male and female combatants and the emergence of a new project, ‘Fambul Tok’ are detailed. The author discusses and compares the Special Court for Sierra Leone and the Truth and Reconciliation Commission to point to gaps in transitional justice that call for community‐based restorative strategies.     

Family succession through adoption in the Chosun Dynasty

Using a unique data source of genealogies of upper-status families, called Bulcheonwye families, we assess how the extent of family succession through adoption changed over five centuries from 1450 to 1949 in Korea. Our analysis shows the continued increase in the share of adopted sons among total family successors up to the end of the 19th century when three out of ten family successors were adopted. The trend of the increasing role of adoption is closely related to the declining number of sons per family, suggesting that not only the rising influence of Confucian culture but also demographic changes increased the demand for adoption. Finally, our comparison provides evidence that the likelihood of achieving high social status was significantly higher among adopted sons than biological ones, suggesting that the socioeconomic potential of adopted sons could be an important factor for adoption decision.     

A survey of data sources for studies of family and population in Korean history

Compared to China and Japan, family and population studies of pre-modern Korea have not been widely available to scholars outside Korea. As a necessary step to increase scholarship in Korean historical demography, we introduce major historical materials currently available in Korea as useful for historical studies, summarizing demographic variables provided, the type of population covered, and the historical period referred in those historical materials. In particular, we focus on genealogies and household registers that provide demographic information of Korean population before the 20th century. We describe major features of those Korean materials as demographic sources, highlighting similarities and differences as compared to corresponding Chinese historical materials. Korean historical data showing their unique features, along with comparability with other East Asian data, have potential to expand the field of historical demography in East Asia.
