Mandibular ramus: an indicator for sex in fragmentary mandible

Mandible is the hardest and most durable bone of the skull exhibiting a high degree of sexual dimorphism. Especially ramus of mandible is subjected to greater stress than any other bone of the skull because of the process of mastication. This study has been performed to establish the osteometric standards for practical use in forensic context over Indian population using mandibular ramus. The sample consists of 116 mandibles of Northern Indian population (M:F; 92:24, mean age 37.4 years), collected from the Department of Forensic Medicine, IMS, BHU, Varanasi. Osteometric informations about five metric parameters (coronoid height, projective height, condylar height, and maximum breadth and minimum breadth of ramus) were taken with sliding calipers. These parameters were subjected to different discriminant function analysis using SPSS 16.0. All parameters showed significant sexual dimorphism (p < 0.001 in all cases) with an overall accuracy of 80.2%, and coronoid height was the single best parameter providing an accuracy of 74.1%.     

Evaluation of two instrumental methods of comparing writing paper

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.

International Relations Theory and Minimum Deterrence

ABSTRACT

India’s government under Narendra Modi represents a return to single party rule. This paper investigates whether and why single party governments in India differ in their extremity of foreign policies from coalition governments. It particularly focuses on how different forms of government influence the saliency, contestation, and enactment of national conceptions about India’s global role. First, I situate India within the academic debate regarding coalitional governments and foreign policy. I suggest that one reason why India challenges scholars‘ assumption is the missing link between partisan conceptions of India’s global role and their institutional representation. Second, I propose a role theoretical approach and argue that the process of self-identification, consisting of ego and anticipated alter expectations, conditions a state’s role set and extreme foreign policy. It is hypothesized that the nature of contestation of national role conceptions varies between factions and fractions because of the nature of India’s party system, as well as the relative significance of external others for India’s identity. Third, I examine instances of role-taking in the field of nuclearization and Sino-Indian relations. Findings suggest that contested role conceptions during single-party rule caused more extreme variances in international role-taking, while coalition governments proved to induce more complementary role-taking processes.     

Achievements and challenges of energy poverty alleviation policies: Evidence from the select states in India

Indian energy sector has undergone a tremendous transformation with consistent government policy interventions since 2000. Against this backdrop, we examine the extent to which energy poverty has decreased due to the expansion of energy services and the significant determinants of energy poverty in select six states in India. Overall, results reveal that absolute multidimensional energy poverty has substantially decreased across all states examined in the study as well as across all income and social groups between 2015 and 2018. Specifically, acute multidimensional energy poverty has reduced by an average of 30% between 2015 and 2018 in six states. At the same time, dependency on biomass remains more or less the same between 2015 and 2018. Results also show that inequality in the access to energy across income and social groups exists, and education is negatively related to energy poverty. Energy poverty has declined by a similar percentage among most employment groups, except for people practicing cattle rearing. Finally, culture is a significant determinant of energy poverty as households with the elderly and more land owned have higher energy poverty, probably due to the easy access to biomass and preference of such households to use it.     

Riding high or nosediving: Development NGOs in the new millennium

This paper attempts to draw some lessons from the experience of development NGOs throughout the world over the last five decades. It starts by describing the meaning of the alternative development paradigm as practised by NGOs. It then examines some of the major socio-political changes that have occurred in recent years, and their impact on development NGOs. Finally, it outlines some key dilemmas facing development NGOs, and their potential implications for their future roles and contributions at the start of the new millennium.     

Sexual Dimorphism in Ulna: An Osteometric Study from India

Determination of sex constitutes the most important element during the identification process of human skeletal remains. Several sex‐specific features of human skeleton have been exploited for sex determination with varying reliability. This study aims to obtain sexual dimorphic standards for ulnae of the north Indian population. Eight measurements were obtained on a sample of 106 ulnae (males‐80, females‐26) in the age range of 25–65 years. The sexual dimorphism index and demarking points were calculated for all the variables. The data were then subjected to stepwise and direct discriminant function analysis. The best discriminator of sex was the maximum length (84.9%) followed by radial notch width (84%). In stepwise analysis, these two variables were selected and provided an accuracy of 88.7% (M‐87.5%, F‐92.3%). The proximal end provided a classification rate of 81.1% (M‐80%, F‐84.6%) with selection of the notch length and olecranon width.     

An osteometric study of northern Indian populations for sexual dimorphism in craniofacial region

Sex identification is an initial crucial objective in the revelation of the complete identity of the human skeleton as it also renders significantly clearer guidance towards age and stature estimation. Population specific standards are of great practical relevance in the present era of increasing population intermixing. Size differences and robusticity are the two well-elaborated pillars holding most of the dimorphic burdens of the skull. This study is designed to explore dimorphic characteristics of the craniofacial region to establish anthropometric standards for contemporary North Indian populations, which have not been available so far. One hundred and twelve adult crania of known age (23-65 years) and sex (M:F; 82:30) were collected in the Department of Forensic Medicine, Institute of Medical Sciences, Banaras Hindu University, Varanasi, India. Ten standard metric parameters of craniofacial region were measured and subjected to stepwise and direct discriminant function analysis employing SPSS 16.00. Bizygomatic breadth emerged as the single best parameter in stepwise analysis, providing an average accuracy of 85.5%.
