Primer residue analysis of ammunition of Indian origin by neutron activation analysis

The primer residues of ammunition manufactured in India have been analysed by neutron activation analysis (NAA). Since NAA is rather insensitive for lead, attention was confined to the elements antimony, barium, copper and mercury. The element/element combinations detected in significant amounts were (Sb), (Ba, Hg), (Ba, Cu, Sb), (Cu, Hg, Sb) and (Hg, Sb). The present study reveals the presence of Hg from mercury fulminate in priming compositions long discontinued in most ammunition of foreign origin. The presence of Hg can be advantageous in certain situations where the matrix on which the residue is deposited contains high levels of antimony such as clothing made of synthetic fibres. Caution is also required in interpreting the Cu values as being solely due to a jacketed projectile.     

A comprehensive ATR-FTIR spectroscopic analysis for the identification and differentiation of lip balms

Lip balm may be encountered as physical evidence in cases involving sexual assaults, homicides, and kidnappings. Lip balm can be used as corroborative evidence by providing a potential link between the victim, accused, and the crime scene. For lip balms to be used as evidence, it is important to understand the diversity and their aging process under different conditions. Therefore, in this study, ATR-FTIR spectroscopy in conjunction with chemometric tools such as principal component analysis (PCA) and linear discriminant analysis (LDA) has been used for the objective identification and differentiation of 20 brands of lip balms. Moreover, lip balms on different substrates and wearing effects over time were also investigated. The results show that the PCA-LDA training accuracy was 92.5%, whereas the validation accuracy comes out to be 83.33%. A blind study using pristine samples was also performed which resulted in 80% PCA-LDA accuracy. PCA-LDA prediction of samples on various substrates showed a higher chemometric prediction accuracy for nonporous substrates (glass, plastic, and steel), than for porous substrates (cotton cloth, cotton swab stick, dry tissue paper, and white paper) for samples kept in room temperature and under sunlight for 15 days. The substrate study showed that the samples from various substrates could effectively generate respective spectra which can help in brand-level identification even after several days. The present method demonstrates a potential for lip balm samples to be used in forensic casework applications.     

Organization and Reporting of Public Financial Accounts: Insights and Policy Implications from the Singapore Budget

This paper analyses the Singapore government budget's organization and reporting structure, and draws lessons and policy implications for improving public financial management practices. The paper finds that Singapore's fiscal marksmanship record has been poor with consistent underestimates of revenue and overestimates of expenditure. Second, subtle divergences from international reporting standards limit the information available and constrain the budget's analytical usefulness in international comparisons. Third, current reporting conventions of the budget fail to provide an adequate representation of the government's fiscal position. Fourth, revised estimates of budgetary balances in line with international reporting standards show a considerable increase in the fiscal space available. The policy implications of these findings are discussed, as well as some reporting changes which can help improve the fiscal marksmanship record, increase public sector transparency and accountability, and facilitate better quality discourse among all stakeholders on public financial management.     

Mapping the linkage between corporate social responsibility and organizational performance along with examining the moderating effect of ownership

Environmental and social initiatives taken by organizations under corporate social responsibility (CSR) have attracted stakeholder's attention and global resonance in the recent times. Alike Western countries, the concept of corporate social responsibility is not new in India rather it has been imbibed in the tradition of Indian society to donate voluntarily for social causes. As a result, a paradigm shift has been noticed where “voluntarism” in CSR has got replaced with a mandatory obligation. This has been made mandatory through an amendment of new Companies Act, 2013. The current study through empirical observations emphases on examining the impact of CSR related activities on the organizational performance with the moderating effect of organizational ownership. A model is proposed and tested using SEM through AMOS. Data were collected from 265 respondents including senior CSR managers and other working professionals of select organizations. The results show a significant and positive relationship between CSR activities and organizational performance. It is also found that organizational ownership has no moderating effect on the relationship between activities conducted under CSR and the performance of the organizations. The analytical finding of the study has a practical implication for the managers of various organizations in the Sonbhadra district of Uttar Pradesh, India.     

Contrasts in Development in Bihar: A Tale of Two Villages

Abstract

The article investigates the economic and social changes that have occurred over the last 30 years in two villages in Bihar, one of the poorest states in India. The two villages are on different development paths: one based on agricultural diversification and local non-agricultural employment, the other dependent on migration to distant labour markets. They therefore connect with India’s overall growth in different ways. Neither development model delivers clearly superior outcomes in terms of incomes, nor are they exhausted, but the long-term sustainability of a migration-led model remains debatable.     

Enhancing security of fingerprints through contextual biometric watermarking

This paper presents a novel digital watermarking technique using face and demographic text data as multiple watermarks for verifying the chain of custody and protecting the integrity of a fingerprint image. The watermarks are embedded in selected texture regions of a fingerprint image using discrete wavelet transform. Experimental results show that modifications in these locations are visually imperceptible and maintain the minutiae details. The integrity of the fingerprint image is verified through the high matching scores obtained from an automatic fingerprint identification system. There is also a high degree of visual correlation between the embedded images, and the extracted images from the watermarked fingerprint. The degree of similarity is computed using pixel-based metrics and human visual system metrics. The results also show that the proposed watermarked fingerprint and the extracted images are resilient to common attacks such as compression, filtering, and noise.     

Y-chromosomal STR haplotypes in two endogamous tribal populations of Karnataka, India

POPULATION: Approximately 5.0 mL of blood sample was collected from a total of 150 men belonging to two tribal populations of coastal Uttar Kannada district of Karnataka, with their informed written consent. Both the populations are endogamous and they belong to the Dravidian linguistic family. Halakki is a tribal group having a population size of c. 3383. They claim that they originally belong to Gujarat and Rajasthan, and migrated through Andhra Pradesh to Karnataka. Kunabhi is also a tribal population, c. 35,214 in number. They were hunters and gatherers but presently they practice agriculture.     

Species identification from dried snake venom

Illegal trade in snake parts has increased enormously. In spite of strict protection under wildlife act, a large number of snakes are being killed ruthlessly in India for venom and skin. Here, an interesting case involving confiscation of crystallized dried snake venom and subsequent DNA-based species identification is reported. The analysis using the universal primers for cytochrome b region of the mitochondrial DNA revealed that the venom was extracted from an Indian cobra (Naja naja). On the basis of this report, the forwarding authority booked a case in the court of law against the accused for illegal hunting of an endangered venomous snake and smuggling of snake venom. This approach thus has immense potential for rapid identification of snake species facing endangerment because of illegal trade. This is also the first report of DNA isolation from dried snake venom for species identification.
