The paper deals with finance-growth relationship across Indian states over 1980–2011 in panel cointegration and causality framework. We apply Engle–Granger two-step procedure for cointegration test in panel setting which takes care of cross-sectional dependence and heterogeneity across states. For panel Granger causality analysis, we employ Dumitrescu and Hurlin (Econ Model 29:1450–1460, 2012) method and apply bootstrapping to account for cross-sectional dependence. We find robust evidence of cointegration between per capita income and credit per capita. Using panel FMOLS, we find that 1 % change in credit per capita results in 0.14 % change in per capita income. Panel Granger causality test reveals that there is bi-directional causality (feedback effects) in the absence of cross-sectional dependence. However, with cross-sectional dependence, we find evidence in favour of supply leading hypothesis. Probable policy implication calls for inclusive financial development and growth strategies in order to mitigate uneven income levels across states.  相似文献

FTIR spectroscopy has been found to be a valuable probe for the analysis of the distribution of organic components such as nitroglycerine in gunshot residues deposited on and around the bullet entrance hole of the clothing of the victim in short range firearm discharges. The method can be utilised for the detection and estimation of organic gunshot residues (OGSR) on the hands and clothing of the shooter. The method is specific and sensitive and is likely to be free from interference from, for example, environmental pollution. The method shows potential to be utilised as a suitable alternative to the widely used SEM-EDX analysis of the total contents of lead, barium and antimony present in the gunshot deposits around the bullet entrance hole. The method was tested in the laboratory and the results were validated by Gas Chromatography-Mass Spectrometry (GC-MS).  相似文献

In the present study, a simple and novel fume–mist technique is described which can be used efficiently to fix the latent fingermarks developed using iodine. It is well known that the residues left over in the fingermarks interact with iodine to give transient brown impressions which disappear in a short time. Also, iodine forms colored complexes with various organic solvents. Based on iodine–fingermark interaction and iodine–solvent complex formation, latent fingermarks were developed on paper surface using iodine fumes which were subsequently fixed by spraying polar and nonpolar solvents. The fingermarks developed with this technique were not only clear but also permanent in nature. The interaction of fingermark residue, iodine, and solvent forming a ternary structure is believed to be a possible reason for the stability of iodine‐developed fingermarks. Ease of method, availability of chemicals, and minimum training make the method adaptable in routine development of forensic fingermarks present on paper surface.  相似文献

Innovative firms enjoy more market benefits by conducting both technological (product and process) and nontechnological (organizational and marketing) innovations. This study aims to examine the relationship between technological innovations and firms’ productivity in Indian pharmaceutical industry in new patent regime. In particular, we analyze the direct impact of product and process innovation on the productivity of 168 Indian pharmaceutical firms over 2000–2013. Findings of this study reveal that technological innovations are positive source of firms’ productivity. However, this relationship varies with types of technological innovations and also ownership structure of firms. Moreover, this study also finds that the impact of technological innovation is stronger for multinational enterprises.  相似文献

Medical advances in transsexualism and the legal implications   总被引:1,自引:0,他引:1  
Transsexualism is a condition wherein an individual's psychological gender is the opposite of his or her anatomic sex. The general belief now among behavioral scientists and physicians is that it is an identifiable and incapacitating disease, which can be diagnosed and successfully treated by reassignment surgery in carefully selected patients. Although many advances have been made in the reassignment surgery techniques, phalloplasty still remains a major challenge; to date, no ideal technique has been developed. The new gender created by the reassignment surgery has, in turn, led to many legal complications for postoperative transsexuals because states and the judiciary have not recognized the new gender. However, with wider acceptance of transsexuals by society, this outlook has changed for the better, with many states amending their laws in accordance with the advances in medical sciences. But in many developed and the developing countries, transsexuals are not given a legal identity, thereby adding to their agonies and miseries.  相似文献

In this paper we describe the identification of constituents of the illicit drugs seized from different regions of eastern India by GC-MS. The constituents were identified to be heroin, acetyl morphine, morphine and acetyl codeine. Quantitative estimation of the constituents were made by GC-MS and HPTLC. In view of non-availability of the authentic samples of drugs of different origin, nothing positive can be said about the origin of illicit drug samples. The possibility of isotopic substitution, an important method for identification of source, was examined from the comparison of the intensity of different (ion) peaks 369 (heroin, m/z=369), 370, 371 and 372 using selective ion monitoring mode. No isotopic substitution in the constituents was observed. Attempts were made to identify the source of the illicit samples from heroin/acetylcodeine ratios in the way described in the literature.  相似文献

Footprints of 725 apparently healthy subjects (395 males and 330 females) between the ages of 18 and 30 years were obtained. A number of measurements were taken on each footprint and converted into suitable indices to overcome the problems of registration, recording and observation.Minimum and maximum probability values for each index and combined probabilities were calculated. From the data, it was found that the maximum combined frequency of an individual in the population was of the order of 10?4 and the minimum combined frequency was several orders of magnitude less. These probability figures do not take into consideration crease marks and other characteristic features. Thus the present study indicates that combined probabilities could provide reasonably reliable circumstantial evidence to link the criminal with the crime.Humps and creases, which often confer individuality on a print, form additional features of the study.  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
