We have examined the antecedents of luxury consumption by conducting a thorough review of literature. Valid scale items for measuring psychological, personal, social, cultural antecedents of luxury consumption in India are proposed. Using Factor Analysis on a sample of 550 responses of the scale items, we have developed a valid questionnaire for Indian luxury consumers. The proposed questionnaire is relevant in context of the proposed model and luxury consumption in India. The proposed questionnaire achieves parsimony in terms of reducing the cardinality of the set of items from 141 to 55.

Aims: Vertical transmission of Hepatitis B virus (HBV) from infected mother to the newborn is the major cause of HBV chronicity. Asialoglycoprotein receptor (ASGPR) expression on hepatocytes has been associated with HBV entry and endocytosis. However, there is a big lacuna regarding expression of ASGPR expression on placental cells and its role in HBV vertical transmission. Methods: 34 HBsAg+ve and 13 healthy pregnant mothers were enrolled along with their newborns. QHBsAg, HBV DNA and liver-function-test were performed among the groups. HBsAg+ve women were grouped into transmitting and non-transmitting mothers on the basis of newborns HBsAg and HBVDNA. Expression of ASGPR and HBsAg were analyzed in placental tissue using Immunohistochemistry and immunofluorescence staining. Peripheral and cord blood-mononuclear cell together with dendritic cells (mDCs and pDCs) were analyzed for the expression of DC-ASGPR, using flow cytometry and QPCR in all subjects. Results: The incidence of HBV vertical transmission to the newborn was 18% among the HBsAg positive pregnant females. HBV transmitting mothers showed increased expression of ASGPR in trophoblasts of placenta. Immunofluorescence microscopy revealed co-localization of HBsAg and ASGPR in placenta as well as in DCs of HBV transmitting mothers. HBV transmitting mothers and their HBsAg+ve newborns showed increased mRNA levels of DC-ASGPR in PBMCS. However, flowcytometry revealed no significant difference in the expression of ASGPR on PBMCs or CBMCs cells between the 2 groups. The HBV transmitting mothers and their HBsAg+ve newborns also showed an increased expression of DC-ASGPR on both myeloid and plasmocytoid dendritic cells compared to HBV non-transmitting mothers and their HBsAg negative newborns. Conclusions: The present work highlights for the first time a role of ASGPR in the intrauterine mother to baby HBV transmission. Blocking of ASGPR appears to be novel therapeutic strategy for prevention of HBV mother to baby vertical transmission.

We report linear and non-linear optical properties of a new quaternary chalcogenide glass series Ge19-ySe63.8Sb17.2Tey (y = 0, 2, 4, 6, 8, 10). In linear optical properties; refractive index, extinction coefficient and the Tauc gap are reported and their variation with Te content has been discussed. In non-linear properties; third order nonlinear susceptibility and non-linear refractive index has been discussed. The variation of non-linear refractive index has also been reported with normalized photon energy. A correlation between the Tauc gap and nonlinear refractive index has been discussed. Results indicate that these materials may find applications in modern optical devices.

Steady state current-voltage characteristics of the amorphous (Se80Te20)98Y2 (Y = Ag, Bi, Ge, Cd) semiconductors at different temperatures are reported. The measurements were performed using direct-current voltage bias to understand the basic conductivity mechanism and to evaluate the impact of each substituent on electrical response. The space charge limited conduction mechanism, and the density of states near Fermi level have been calculated. The difference in electrical response due to different substitutions in the glassy matrix is analyzed.
