Characterization and assessment of inks on sensitive documents for absolute/relative age determination is the challenging forensic problem in spite of practical difficulties. Tagging of ballpoint pen ink with suitable taggant(s) is a unique method to come out with definitive inferences on the detection of forgery in documents written with ballpoint pens. Selection of a proper taggant primarily depends on sensitivity of analytical determination and their absence in normal varieties of ink used for document writing. Rare-earth elements, from all technical considerations can be potential taggant(s) for inks. To ensure more compatibility with ink, 13 rare-earth thenoyltrifluoroacetonate chelates were prepared and characterized. The ballpoint pen inks were tagged with rare-earth thenoyltrifluoroacetonate chelates individually at about 1-100 ppm level depending on sensitivity of element under suitable optimized experimental conditions and instrumental sensitivity. Aliquots of such tagged ink having varying amounts of taggants were analyzed by ICP-MS and INAA. Satisfactory recoveries and a good linear relationship of intensity (signal) against concentrations/amounts were observed. Under the optimized experimental conditions, the detection limits were worked out. This study of tagging metal ions in combination with ICP-MS and NAA as an analytical tool can allow to draw various combination options based on different rare-earth chelates as suitable materials for tagging of ballpoint pen inks for absolute/relative age determination to aid in document related crime examination. The advantages and limitations of proposed analytical techniques are discussed. 相似文献

Sealing wax is used for maintaining the integrity and authenticity of a document or physical evidence. Any tampering with the seal calls into question the overall integrity and authenticity of the tangible evidence or document. In these circumstances, determining the authenticity of the sealing material (physical and chemical) becomes imperative. In this study, ATR-FTIR spectroscopy supported by chemometrics has been used to differentiate sealing wax samples belonging to 12 different brands available across India. All the samples were first melted, cooled, and then analyzed using ATR-FTIR spectroscopy in the mid-infrared region (4000–600 cm−1). The obtained spectra were first examined visually for the presence of different functional groups. Principal component analysis (PCA) and principal component analysis-linear discriminant analysis (PCA-LDA) were employed to analyze the sample clustering patterns and to categorize them into their respective groups, respectively. For classification, a PCA-LDA training model was applied, and it demonstrated 95.83% accuracy. The validation test resulted in an accuracy of 83.33%. PCA-LDA model offered 100% accurate prediction for samples on various substrates, including cloth, cardboard, and paper. A blind study was also performed using five unknown samples, which were accurately classified into their respective groups. PCA-LDA model will be helpful in providing investigative leads by linking a questioned sealing wax sample with its respective group. 相似文献

The outreach of microfinance program is considered to be a means to enhance the economic opportunities among the women section of the population and thus have its far reaching implications to the empowerment of women. In this respect, a wide variation in the outreach of microfinance program to the women poor households is observed across countries of the world. In India, the states having higher level of microfinance outreach are also the states with a relatively high level of women empowerment. It is, thus, predicted that an all-inclusive microfinance system would strengthen the process of financial inclusion in India and thereby would promote women’s empowerment. 相似文献

‘Gender mainstreaming’ has been regarded as one of the strongest approaches to deal with the issue of equality policy for women. In order to mainstream women in the political process, a number of NGOs have been carrying out different programs in Bangladesh for building awareness among women so that they could opt for participation in the political process. The paper analyzes the role of NGOs in the process of mainstreaming gender in politics in Bangladesh in general and in the enactment of the Local Government (Union Parishad) (Second Amendment) Act of 1997 in particular. Based on empirical data collected through an open-ended structured questionnaire and available secondary data, the study findings reveal that despite having no formal access to the policy process, NGOs augment participation of women in the political process through informal means as is exemplified by their training programs that enhance women's social and economic status. 相似文献

Community Politics has been a political strategy of the Liberal Party, now the Liberal Democrats, since 1970. It involves a critique of traditional representational relationships and argues for a participatory democracy based upon deliberation to build consensus out of competing interests. Whilst the associated campaigning techniques have made the third party an important force in local government, this article uses new empirical evidence to assess the success of the strategy in transforming representational relationships and extending popular participation in local government. It is argued that its success in respect of these objectives has been limited, principally because of popular disenchantment with political parties and the inherent tensions and limitations that accompany popular participation in deliberative democratic structures. 相似文献

The Indian wild pig (Sus scrofa cristatus) is a protected species and listed in the Indian Wildlife (Protection) Act, 1972. The wild pig is often hunted illegally and sold in market as meat warranting punishment under law. To avoid confusion in identification of these two subspecies during wildlife forensic examinations, we describe genetic differentiation of Indian wild and domestic pigs using a molecular technique. Analysis of sequence generated from the partial fragment (421 bp) of mitochondrial DNA (mtDNA) cytochrome b (Cyt b) gene exhibited unambiguous (> 3%) genetic variation between Indian wild and domestic pigs. We observed nine forensically informative nucleotide sequence (FINS) variations between Indian wild and domestic pigs. The overall genetic variation described in this study is helpful in forensic identification of the biological samples of wild and domestic pigs. It also helped in differentiating the Indian wild pig from other wild pig races. This study indicates that domestic pigs in India are not descendent of the Indian wild pig, however; they are closer to the other wild pig races found in Asia and Europe. 相似文献
