改制上市不是灵丹妙药--由日本的教训看我国银行改革的制度缺陷与制度设计

目前,我国国有商业银行的改革进入到攻坚阶段,改制上市成为当前国有商业银行改革的目标和救命稻草。但日本银行业历经十年的改革,却仍未取得实质进展的教训提醒我们,仅仅实现形式上的产权多元化和上市并不能从根本上解决银行业的问题,关键是要吸取日本银行改革的教训,分析国有商业银行改革中存在哪些制度缺陷,然后标本兼治,大刀阔斧地进行一系列制度创新才能把国有商业银行打造成富有效率、规范运作的现代金融企业。

DOES DROPPING OUT OF SCHOOL MEAN DROPPING INTO DELINQUENCY?*

Approximately one third of U.S. high‐school freshmen do not earn their high‐school diploma on time. For African‐American and Hispanic students, this figure nearly reaches one half. The long‐term economic consequences of dropping out of school for both the student and the larger community have been well documented. It has also been argued that school dropouts put themselves at a higher risk for delinquent and criminal behavior when they leave school. Although it seems plausible that dropping out might increase the potential for delinquent conduct, another view states that dropping out is simply the final event in a long, gradual process of disenchantment and disengagement from school. Dropouts show evidence of school failure and developmental problems years in advance. It has been argued, therefore, that the actual event of finally leaving school has no causal effect on criminal or delinquent behavior because it has been so long in coming. In this article, we examine the effect of leaving school early, and the reason for dropping out, on delinquent behavior with the use of panel data models from the National Longitudinal Survey of Youth 1997 Cohort (NLSY97). Through an appeal to identity theory, we hypothesize that the effect of dropping out is not uniform but varies by the reason for leaving school, gender, and time. This conjecture receives only partial empirical support. Implications for future work in the area are discussed.     

CO‐OFFENDING AND THE DEVELOPMENT OF THE DELINQUENT CAREER*

This article examines the role of co‐offending in the development of the delinquent career. Hypotheses derived from Reiss's (1986, 1988) taxonomic theory of co‐offending are tested, using police‐reported data on the delinquent careers and co‐offending of 55,336 Canadian offenders. Support is found for a taxonomic theory and for age‐related and functional theories of co‐offending. The taxonomy consists of two types of offenders—high activity (3 percent) and low activity (97 percent)—whose co‐offending patterns differ during the teenage years but not during childhood. For low‐activity offenders as teenagers, the proportion of co‐offenses decreases with criminal experience. The rate of co‐offending by high‐activity offenders as teenagers is lower at onset than for low‐activity offenders, and it varies little with criminal experience. For both offender types, the proportion of co‐offenses decreases with age, is slightly less in males, and varies with the type of offense. For both offender types, the proportion of co‐offenses in childhood offending is greater than in the teenage years and is unrelated to the offender's age or criminal experience.     

RACIAL ANIMOSITY AND INTERRACIAL CRIME*

The primary objective of this study is to determine the effect of a victim's race on the likelihood of him or her being seriously injured during the commission of an interracial crime. We also assess the probability of a homicide occurring during an interracial crime. A multilevel city analysis shows that black offenders are no more apt than white offenders to injure their victims seriously during an interracial robbery or rape. A black offender also does not have a greater proclivity to kill his or her victim during the commission of an interracial crime. Some evidence suggests that white victims are more likely than black victims to suffer serious physical harm during an aggravated assault. Results also reveal that contextual factors related to racial animosity, such as residential segregation, white‐to‐black economic inequality, and black‐to‐white unemployment, fail to have any moderating effect on either the severity of victim injury or the likelihood of a homicide occurring during an interracial crime. Overall, the results generated in this study tend to cast doubt on the validity of racial animosity theory. Our findings also lead us to question the veracity of the oftenmade claim that black‐on‐white crimes are punished more severely because these types of offenses are somehow more heinous in circumstance. At least in regard to serious victim injury and victim death, black‐on‐white crime is no more violent than white‐on‐black crime.     

Classification of Glass Fragments Based on Elemental Composition and Refractive Index*

Abstract: The aim of this study was to assess the efficiency of likelihood ratio (LR)‐based measures when they are applied to solving various classification problems for glass objects which are described by elemental composition, and refractive index (RI) values, and compare LR‐based methods to other classification methods such as support vector machines (SVM) and naïve Bayes classifiers (NBC). One hundred and fifty‐three glass objects (23 building windows, 25 bulbs, 32 car windows, 57 containers, and 16 headlamps) were analyzed by scanning electron microscopy coupled with an energy dispersive X‐ray spectrometer. Refractive indices for building and car windows were measured before (RI_b), and after (RI_a) an annealing process. The proposed scheme for glass fragment(s) classification demonstrates some efficiency, although the classification of car windows (c) and building windows (w) must be treated carefully. This is because of their very similar elemental content. However, a combination of elemental content and information on the change in RI during annealing (ΔRI = RI_a?RI_b) gave very promising results. A LR model for the classification of glass fragments into use‐type categories for forensic purposes gives slightly higher misclassification rates than SVM and NBC. However, the observed differences between results obtained by all three approaches were very similar, especially when applied to the car window and building window classification problem. Therefore, the LR model can be recommended because of the ease of interpretation of LR‐based measures of certainty.     

A Fatal Shot with a Signal Flare—A Crime Reconstruction*

Abstract: A reconstruction of an incident of a fatal wounding of a football fan with a parachute flare was performed. Physical and chemical examinations of the victim’s trousers and parts of a flare removed from the wound in his leg were performed by means of an optical microscope and a scanning electron microscope coupled with an energy dispersive X‐ray spectrometer. Signs of burning were seen on the front upper part of the trousers, including a 35–40 mm circular hole with melted and charred edges. Postblast residue present on the surface of the trousers contained strontium, magnesium, potassium, and chlorine. Also the case files—the medical reports and the witnesses’ testimonies—were thoroughly studied. It has been found that the evidence collected in the case supported the version of the victim being shot by another person from a distance.     

Application of Raman Spectroscopy and Surface‐Enhanced Raman Scattering to the Analysis of Synthetic Dyes Found in Ballpoint Pen Inks*

Abstract: The applicability of Raman spectroscopy and surface‐enhanced Raman scattering (SERS) to the analysis of synthetic dyes commonly found in ballpoint inks was investigated in a comparative study. Spectra of 10 dyes were obtained using a dispersive system (633 nm, 785 nm lasers) and a Fourier transform system (1064 nm laser) under different analytical conditions (e.g., powdered pigments, solutions, thin layer chromatography [TLC] spots). While high fluorescence background and poor spectral quality often characterized the normal Raman spectra of the dyes studied, SERS was found to be generally helpful. Additionally, dye standards and a single ballpoint ink were developed on a TLC plate following a typical ink analysis procedure. SERS spectra were successfully collected directly from the TLC plate, thus demonstrating a possible forensic application for the technique.
