In 1999, Sampson and Raudenbush published an influential article in the American Sociological Review on the link between disorder and crime in urban neighborhoods. The present article offers a reinterpretation of their 1999 article based on the contentions that: (1) their interpretation of the broken windows thesis is imprecise, and (2) there is an alternative interpretation of their findings that was not considered. Based on these contentions, and contrary to Sampson and Raudenbush's (1999) assertions, the authors conclude that the results of Sampson and Raudenbush's study are not inconsistent with the broken windows thesis and therefore should not be used as empirical evidence against it. 相似文献

This article, written by Prateek Joshi in close collaboration with Colonel Narender “Bull” Kumar, discusses the development of the conflict over the Siachen Glacier between India and Pakistan. It sets out the Siachen Conflict in the broad framework of the Great Game and explains the crucial role of Colonel Narender “Bull” Kumar's Siachen expeditions in rekindling this old flashpoint in High Asia. Based on Colonel Kumar's two expeditions to the Siachen Glacier region, namely the Teram Kangri expedition in 1978 and the Siachen expedition in 1981, it discusses the perspectives regarding the dispute and its relation to reviving a consciousness of the Great Game. The first perspective discusses Colonel Kumar's expeditions in light of the Indo-Pak conflict as these two visits became the precursor to Operation Meghdoot, following which the Indian Army occupied the Siachen Glacier in 1984. The second perspective discusses a crucial cartographic blank which was filled only after Colonel Kumar's Siachen expedition. 相似文献

In this study, we describe a forensic case dealing with the identification of the source of the processed ivory object by DNA analysis. Two pieces of Lord Krishna's idols from a shop were confiscated by an investigating agency of the Indian government and forwarded to us to identify the source of its origin. We succeeded in isolating DNA from both processed ivory idols by using the phenol/chloroform DNA extraction method. The extracted DNA was subjected to PCR amplification using an elephant-specific mitochondrial DNA (mtDNA) D-loop marker. DNA sequence analysis of the amplified fragment of mtDNA D-loop region confirmed that the idols were consistent with Asian elephant with 99% similarity. 相似文献

An organization had approved the sample of writing paper, and accordingly the supplier had to execute the supply. The supply received was suspected to be of different quality from approved one. The organization sent the samples for comparison to the Forensic Science Laboratory. Both the approved and supplied samples were compared using Tensile Testing Method with the Material Testing Machine and Fluorescence and spectral analysis using the Video Spectral Comparator (VSC2000). The difference between the mean loads at peak before rupture in the tensile testing mode for the two samples was about 33%. The two samples differed significantly in terms of UV fluorescence, and there was about 5% average difference in the percentage of maximum reflected intensity in the wavelength region of 400-900 nm. It has been observed in this study that these two methods can adequately distinguish paper samples of different origin. 相似文献

Dental forensics forms a vital branch of forensic science which deals with proper handling, examination and evaluation of dental evidences for identification of victims of crime, accidents or calamities. Therefore skull and teeth often provide the identification material. The aim of the study was to investigate the accuracy of odontometric methods in sex determination of permanent teeth and to compute new formula to differentiate male and female teeth using discriminant function analysis for South Indian population. A total of 100 subjects were selected for the study from a parent population of 4800 students by simple random sampling method. Alginate impressions of the upper dental arch were made and casts were poured immediately. A digital vernier calliper was used for the measurement of all upper anteriors. Twelve different tooth measurements were recorded and from those two indexes have been computed. Statistical analysis was performed using the SPSS version 17.0 software. All the predictor variables were subjected to stepwise discriminant function analysis which optimally separates the genders and a best discriminant function was generated. In all the observed mean dimensions, male values exceed the female values. Student's 't' test for the different predictor variables of all teeth selected between male and females were found significant (p < 0.05). Very high significance was found in mean MD of 11, 12 and 13 and |c| of 23. The variables exhibiting best discriminant powers were mesiodistal width of both upper central incisors, DB-ML of 13 and canine crown module of 13. Sexual dimorphism in the size of permanent teeth differs from one population to the other and hence the standards set for one population could not be applied for another population. Hence this technique would be a simple, quick, cost effective, reliable and accurate for sex determination. 相似文献

This study examines Merton's Classical Strain Theory (1938) as a causative factor in intimate partner violence among college students. We theorize that college students experience general life strain and cumulative strain as they pursue the goal of a college degree. We test this strain on the likelihood of using intimate partner violence. Strain due to unrealistic expectations of intimate partnership and economic strain are also examined. The analysis examines the following causative factors representing strain: 1) the College Undergraduate Stress Scale (Renner & Mackin, 1998); 2) cumulative academic strain measured by college classification; 3) cumulative intimate partner strain measured as the length of time in the relationship; 4) academic strain measured by number of hours studied weekly, and 5) economic strain measured by number of hours worked weekly. Additionally, we examine the extent to which gender and race/ethnicity differentially affect intimate partner in the context of these measures of strain. The Conflict Tactics Scales II (Straus et al, 1996) are used to measure dating violence and include indicators for sexual coercion, physical aggression, injury, and psychological aggression. Data were collected from 142 students in lower-division classes from Texas Tech University. Results show that general strain and cumulative intimate partner strain increase the use of dating violence among college students. The longer dating partners are in a relationship, the higher the chances of psychological aggression, physical assault, and sexual coercion. Converse to our expectations, time spent working reduces psychological aggression due to reducing time spent together rather than reflecting economic strain. 相似文献

Calls for truth commissions and similar public processes topromote social reconciliation after national conflicts oftenreflect admirable aspirations but muddy thinking. This subtleand careful analysis of the processes of political reconciliationafter periods of mass violence opens for analysis the spectrumof potential meanings associated with reconciliation,ranging from social unity and harmony to the cessation of physicalviolence.
