Conceptualizing and Measuring Ethnic Politics: An Institutional Complement to Demographic, Behavioral, and Cognitive Approaches

The influence of ??ethnic politics?? has been demonstrated in a range of empirical studies of economic growth, violence, and public goods provision. While others have raised concerns about the measurement of ethnic variables in these works, we seek to situate such discussions within a more thoroughgoing conceptual analysis. Specifically, we argue that four conceptual approaches??demographic, cognitive, behavioral, and institutional??have been used to develop theories in which the mechanism that relates causes to outcomes is ethnic political competition. Within this literature, we believe that institutional approaches have been relatively under-appreciated, and we attempt to address that imbalance. We begin by critically reviewing the three main ways in which ethnic variables have been specified and operationalized, delineating the assumptions and trade-offs underlying their use. Next, we describe an institutional approach to the study of ethnic politics, which focuses on the rules and procedures for differentiating ethnic categories. We propose some new indices based on this latter approach that might be developed and used in future research. Subsequently, we analyze the relationship between each of these approaches and patterns of ethnic political competition in a set of six country cases, highlighting their strengths and weaknesses, as well as theoretical links between them.     

Coping with Work Stress in Police Employees

Present study endeavored to investigate the role of coping in work stress of police employees. A 3 × 2 factorial design with three levels of job hierarchy (officers, sub-inspectors, and constables) and two levels of job tenure [short job tenure (0–10 year) and long job tenure (above 10 year)] was used in present study. A total of 240 police personnel from Gorakhpur Zone (India) participated as respondents. Objective Work Stress Scale, Feeling of Work Stress Scale (Cooper 1983), and Coping Scale (Carver et al. 1989) were used to determine the level of work stress and coping of the police employees. ANOVA results revealed that the level of work stress varied across different groups of police personnel. More specifically, objective work stress was found greater in sub-inspectors than constables and officers while constables reported more feeling of work stress than sub-inspectors and officers, respectively. Furthermore, the different groups of police personnel differed on various forms of coping response, in which officers used more active- and adaptive-related coping strategies than sub-inspectors and constables, respectively. Contrary to this, constables used more maladaptive coping strategies than sub-inspectors and officers. Correlation results evinced that active- and adaptive-related coping responses have an inverse link with work stress, whereas maladaptive coping responses have a positive relationship with work stress. Findings have been discussed in the light of organizational and personal factors.     

‘Full’ Compensation Criteria: An Enquiry into Relative Merits

The principle of full compensation is said to restore the victim of an accident to the position he was in before the tort. The conventional pre-tort position of the victim is taken to be the one in which he bears no accident losses at all. Therefore, a negligent injurer is required to compensate his victim fully. In an interesting paper in this journal, Van Wijck and Winters (2001) have reinterpreted the pre-tort position of the victim, and proposed an alternative specification of liability for the purpose of compensation. We study the relative merits of the two compensation criteria. We show that while the alternative compensation criterion is indeed insightful from economic as well as legal point of view, at the same time it suffers from some serious limitations.     

Development of latent fingerprints on compact disc and its effect on subsequent data recovery

Chance fingerprints may be found on every type of surfaces of contact and when they are latent, need to be developed by various methods. The type of surface on which latent prints are to be developed is one of the important factors when a choice for a method of development is to be made. The matter becomes more crucial when the surface is unique like a compact disc containing digital data. In this case, to develop the fingerprints is not the only matter to be taken care of but also, is very important to select such a method which may not effect the stored data and its retrieval. In present investigation, various methods have been tried to develop fingerprints on the writing surface of a CD and results are discussed with respect to their development as well as its effect on stored data and data retrieval.     

Age of retinal hemorrhages by iron detection: an animal model

Intraretinal hemorrhages have been found in some abusively injured infants and children. Intraretinal hemosiderin has been proposed as an indication of previous injury. The limits of the accuracy of the proposal have not been established. Experimental central retinal vein occlusion (CRVO) was produced in 20 eyes of adult rhesus monkeys as part of ongoing research by one of the authors (SSH). The animal experiments were conducted in accordance with a research protocol approved by the Animal Care Committee, University of Iowa. CRVO produced diffuse intraretinal hemorrhages. Clinical ocular examinations assessed the onset and time course of retinal hemorrhages. Enucleation specimens were used to assess hemosiderin in the retinas. Hemosiderin was detected within 2 days of induction of retinal hemorrhages. It was detected in only 4 of 11 eyes (36%) studied more than 1 week following induction of hemorrhages. In 2 eyes, hemosiderin was found 9 and 16.8 months after development of hemorrhages. Hemosiderin can represent organization of current hemorrhage rather than evidence of prior hemorrhage. This study does not allow specifying the duration of hemorrhages with greater precision than "more than 2 days prior to death," and that, only if there is no survival interval. Failure to detect hemosiderin does not exclude prior retinal hemorrhages.     

Estimation of stature from foot and shoe measurements by multiplication factors: A revised attempt

Estimation of stature from foot and shoe measurements using multiplication factors is well known. It is a simple method and it is used very frequently as a ready reckoner in forensic anthropology. However the individual error is quite large. In the present work an attempt has been made to evolve revised multiplication factors to reduce this error so that this method (multiplication factor) can be used more effectively with smaller error.     

Screening and confirmation of drugs in urine: interference of hordenine with the immunoassays and thin layer chromatography methods.

Hordenine cross-reacted with various enzyme linked immunosorbent assay (ELISA) or radioimmunoassay (RIA) kits used for the screening of urine samples. Morphine-ELISA kit was most sensitive, whereas etorphine- and buprenorphine-ELISA kits were least sensitive to hordenine cross-reactivity. Hordenine also interfered with the thin layer chromatography of oxymorphone, hydromorphone and apomorphine. The major source of hordenine in humans is beer brewed from barley, whereas the major source of hordenine in horses is canary grass or barley. Therefore, the presence of hordenine in the urine of humans consuming beer or in the urine of horses consuming canary grass may give false positive values when the immunoassay and TLC methods are used for the screening of the urine sample. In order to distinguish hordenine from the opiate drugs, simple and sensitive gas chromatographic/mass spectrometric (GC/MS) and high performance liquid chromatographic (HPLC) methods have been developed in this study.     

Rapid and non-destructive approach for characterization and differentiation of sealing wax using ATR-FTIR spectroscopy

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.
