The Use of Laser Microdissection in Forensic Sexual Assault Casework: Pros and Cons Compared to Standard Methods

Sexual assault samples are among the most frequently analyzed in a forensic laboratory. These account for almost half of all samples processed routinely, and a large portion of these cases remain unsolved. These samples often pose problems to traditional analytic methods of identification because they consist most frequently of cell mixtures from at least two contributors: the victim (usually female) and the perpetrator (usually male). In this study, we propose the use of current preliminary testing for sperm detection in order to determine the chances of success when faced with samples which can be good candidates to undergo analysis with the laser microdissection technology. Also, we used laser microdissection technology to capture fluorescently stained cells of interest differentiated by gender. Collected materials were then used for DNA genotyping with commercially available amplification kits such as Minifiler, Identifiler Plus, NGM, and Y‐Filer. Both the methodology and the quality of the results were evaluated to assess the pros and cons of laser microdissection compared with standard methods. Overall, the combination of fluorescent staining combined with the Minifiler amplification kit provided the best results for autosomal markers, whereas the Y‐Filer kit returned the expected results regardless of the used method.     

试论我国商业秘密的保护

在社会主义市场经济发展中,关于商业秘密的法律保护和自我保护问题日益显现,并越来越受到人们的关注。少数单位和个人以不正当手段窃取商业秘密不仅是对商业秘密权利人合法权益和社会主义市场经济正常秩序的严重损害,而且也极大地挫伤了商业秘密权利人的生产积极性。因此,要有效地保护商业秘密,必须了解商业秘密的定义、构成要件和特征,知悉商业秘密的法律保护方法,其中包括我国现行立法对于商业秘密保护的各种规定,同时,还应掌握对商业秘密法律保护有力补充的几种自我保护方法。     

SELECTIVE INCAPACITATION,THREE STRIKES,AND THE PROBLEM OF AGING PRISON POPULATIONS: USING SIMULATION MODELING TO SEE THE FUTURE*

Research Summary: The growth of prison populations over the last three decades is a great source of concern for policy makers and observers. One mechanism by which this growth occurs is via sentencing reforms that extend length of stay for certain categories of offenders. This has the effect of aging prison populations, which is problematic for many reasons. Apart from the increased financial burdens entailed in caring for older prisoners, it is also important to consider the intent of reforms in evaluating them. Of late, sentencing reform has become increasingly focused on the selective incapacitation of dangerous offenders. Policies that have the effect of aging the prison population are problematic from this perspective due to the diminishing returns realized with respect to incapacitation as offenders age. Dynamic systems simulation analysis is employed to investigate the likely consequences of recent sentencing reforms that increase length of stay for some offenders. These analyses indicate that the effects of recent reforms may not be as dramatic as some observers have predicted, but they suggest that the consideration of alternatives to incarceration for elderly offenders is warranted from the standpoint of cost considerations as well as that of selective incapacitation. Policy Implications: The results indicate that California's Three Strikes law will not accelerate the rate of growth of the elderly prison population. However, even without increasing the proportional representation of elderly prisoners, the number of elderly prisoners is expected to grow substantially over the next three decades. These prisoners will strain criminal justice system resources while presenting little public safety threat. State criminal justice policy makers and their constituents should closely examine laws that impose very long stays without discretionary release, as these statutes may contribute to the production of elderly prisoners. This problem is particularly pronounced in Three Strikes and other habitual offender laws that use retrospective methods to identify habitual offenders. Additionally, the effects of reforms lengthening stay for some offenders must be considered in light of cumulative effects of sentencing reform resulting in changes to the demographic structure of the prison population overall. Dynamic systems simulation modeling is presented as a valuable policy‐making tool, as it allows the policy analyst to examine the potential impacts of laws in the absence of data suitable for conventional statistical analyses.

Venezuela,April 2002: Coup or Popular Rebellion? The Myth of a United Venezuela

This article assesses the merits of opposing National Assembly reports into the coup against President Chávez of Venezuela in April 2002. Looking at the historical context and the content of the reports, it argues that the two opposing accounts reflect a class division that has always existed in Venezuela but has been officially denied. It concludes that a possible exit from the stalemate could be that the opposition accept the reality of this class division and therefore the Chávez government as a legitimate representative of the popular classes. This, however, is unlikely in the present circumstances.     

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.     

Comparative Politics and the Synthetic Control Method

In recent years, a widespread consensus has emerged about the necessity of establishing bridges between quantitative and qualitative approaches to empirical research in political science. In this article, we discuss the use of the synthetic control method as a way to bridge the quantitative/qualitative divide in comparative politics. The synthetic control method provides a systematic way to choose comparison units in comparative case studies. This systematization opens the door to precise quantitative inference in small‐sample comparative studies, without precluding the application of qualitative approaches. Borrowing the expression from Sidney Tarrow, the synthetic control method allows researchers to put “qualitative flesh on quantitative bones.” We illustrate the main ideas behind the synthetic control method by estimating the economic impact of the 1990 German reunification on West Germany.
