Abstract

The present study entitled "aggression among adolescents across different socio-economic developmental strata-A comparative study" was undertaken in the Ludhiana district of Punjab state. The study was designed to compare the aggression among adolescent boys and girls across different socio-economic and developmental strata. The sample comprised of 400 adolescents (200 boys and 200 girls) in the age group of 13-17 years equally distributed over two socio-economic developmental strata, i.e. low and middle. Socio-economic status scale by Bharadwaj and Buss-Durkee aggression scale by Sultama were used to collect the data. Results revealed that adolescent boys were more assaultive, negative and verbally aggressive than adolescent girls, while girls were more suspicious than boys. A significant mean difference was found among low and middle socio-economic developmental adolescents. Low socio-economic developmental adolescents were more assaultive and suspicious than their middle socio-economic development counterparts while middle socio-economic developmental adolescents supersedes low socioeconomic development adolescents in expression of indirect aggression.

Abstract

The present study attempts to assess the lifestyle of elders and the related stress of their caregivers due to caregiving. Lifestyle is a mixture of habits; conventional ways of doing things, reasoned actions and bundle of behaviors' that makes sense to the elders as well as their family caregivers. A purposive sample of 80 elderly and their one family caregivers (80) was selected from the Ranchi town, which was stratified on the basis of age, gender and socio- economic status (SES). Adopting a 2x2x2 factorial design data was collected using Lifestyle Questionnaire by Mathur, and Aurora, (2007) and Kingston Caregivers Stress Scale (KCSS) by Hopkings, and Kilik, (2012). It was found that lifestyle of the sample groups ranged from moderate to good category depending upon age, gender and SES. On the three dimensions of caregivers stress, the score was highest on stress related to financial issues, family issues and caregiving issues respectively. The male, young old and high SES elderly had a better lifestyle than the female, old old and low SES elders. Lifestyle of the elderly was found to be negatively correlated with caregiving stress indicating that better the lifestyle lesser would be the caregiving stress.

Abstract

The explosive increase in the number of Internet users boost the demand for high speed data capacity in Access networks, Metro networks and especially in Core networks. The systems with 10 Gbit/s and 40 Gbit/s have already seen much of the research and now the focus has shifted to even higher datarates of 100 Gbit/s and 160 Gbit/s per wavelength. Since optical data transmission with conventional modulation formats based on on-off-keying (OOK) at such high datarates is adversely affected by linear and non-linear effects, it’s important to look at other modulation formats offering resistance to these effects. Polarization Multiplexing Quadrature Phase Shift Keying PM-QPSK is one such modulation format which must be studied at ultra-high data rate of 160 Gbit/s. In this paper the performance of a single channel PM-QPSK having datarate of 160 Gbit/s has been investigated with coherent detection of the optical signal along with the digital signal processing for dispersion compensation in a scenario of rapid increase in demand for datarate. Here the study has been carried out on 900kms of uncompensated SSMF and NZDSF with the different launch powers and also OSNR requirement for the system in back to back configuration has been derived. Also an increase in optical reach has been achieved through two methods first being Distributed Raman Amplification (DRA) and pump power has been optimized for the same and second by using shorter fiber spans with EDFA amplification only.

Abstract

The present study entitled "gender difference in aggressive behaviour of adolescents" was undertaken in the Ludhiana district of Punjab. The study was designed to compare aggressive behaviour of adolescent boys and girls across low and middle socio-economic strata. The sample comprised of 400 adolescents (200 boys and 200 girls) of the age group 13-17 years equally distributed over two different socio-economic strata i.e. low and middle (200 LSES and 200 MSES). Socio-economic status scale by Bharadwaj and Buss-Durkee aggression scale by Sultania, was used in this research study. Gender differentials revealed that adolescent boys were more assaultive, negative and verbally aggressive than adolescent girls, while girls were more suspicious than boys. Low socio-economic status boys outnumbered girls in expression of negative behaviour and verbal aggression. In middle socio-economic status boys are more assaultive than girls while girls are more irritative and suspicious than boys. Mean difference showed boys exceed girls in showing assaultive behaviour, negativism and expression of verbal aggressive while girls were more suspicious than boys. Two way interaction involving socioeconomic status and gender in different dimensions of aggression showed boys with low socioeconomic status had nearly same intensity of negativism as girls with middle socio-economic status followed by boys with middle socio-economic status. The lowest level of negativism was found in girls with low socio-economic status.
