Political Economy of Tribal Development : A Case Study of Andhra Pradesh
The tribal population in the State of Andhra Pradesh, and in the country as a whole, is the most deprived and vulnerable community that faces severe economic exclusion. Although certain constitutional safeguards are provided, no significant economic, social and political mobility has taken place across this community. Contrary to Scheduled Castes and other Backward Castes who witnessed certain degrees of progress because of protective discrimination policies of the government, the Scheduled Tribes remain abysmally backward and socially excluded, still living in harsh environs. Our paper on "Political Economy of Tribal Development : A Case Study of Andhra Pradesh", delineates the situation of the Scheduled Tribes in the background of various policies of the state during the successive plan periods and its impact on their socio-economic mobility. Politically, this community is the most voiceless in the state. Their unsecured livelihood position in terms of lack of legal entitlements of the resources they use, both land and non-timber forest produce, push them into deep economic vulnerability. The paper also discusses the implications of the new act - Forest Right Act, 2006, on the livelihood security of the tribal communities and whether this act will finally lead to the inclusion of these people into the mainstream.Andhra Pradesh, India, economic exclusion, caste system, socio-economic mobility, Forest Right Act 2006
The role of shear in dissipative gravitational collapse
In this paper we investigate the physics of a radiating star undergoing
dissipative collapse in the form of a radial heat flux. Our treatment clearly
demonstrates how the presence of shear affects the collapse process; we are in
a position to contrast the physical features of the collapsing sphere in the
presence of shear with the shear-free case. By employing a causal heat
transport equation of the Maxwell-Cattaneo form we show that the shear leads to
an enhancement of the core temperature thus emphasizing that relaxational
effects cannot be ignored when the star leaves hydrostatic equilibrium.Comment: 15 pages, To appear in Int. J. Mod. Phys.
Flooding attacks to internet threat monitors (ITM): Modeling and counter measures using botnet and honeypots
The Internet Threat Monitoring (ITM),is a globally scoped Internet monitoring
system whose goal is to measure, detect, characterize, and track threats such
as distribute denial of service(DDoS) attacks and worms. To block the
monitoring system in the internet the attackers are targeted the ITM system. In
this paper we address flooding attack against ITM system in which the attacker
attempt to exhaust the network and ITM's resources, such as network bandwidth,
computing power, or operating system data structures by sending the malicious
traffic. We propose an information-theoretic frame work that models the
flooding attacks using Botnet on ITM. Based on this model we generalize the
flooding attacks and propose an effective attack detection using Honeypots
Effects of Pisolithus Tinctorius and Laccaria Fraterna on the Growth and Mycorrfflzal Development of Pinuspatula Seedlings*)
Vegetative inoculum of Pisolithus tinctorius and Laccariafraterna were inoculated to Pinuspatula seedlings grown in both steam sterilized and unsterilized shola soil. After 4 months of seedling growth, 10 seedlings from each treatment were harvested and various growth parameters were studied. Inoculation of these two fungi resulted in the production of ectomycorrhizas and increase in growth of P. patula seedlings when compared to uninoculated seedlings. Laccariafraterna inoculated seedlings showed more number of mycorrhizas than P. tinctorius inoculated seedlings at the end of one year. Both these fungi poorly colonized the root system in both soil treatments. There was no significant difference between these two fungi in improving the seedling growth in the nursery
Star-forming Galaxies in the 'Redshift Desert'
We describe results of optical and near-IR observations of a large
spectroscopic sample of star-forming galaxies photometrically-selected to lie
in the redshift range 1.4 < z < 2.5, often called the ``redshift desert''
because of historical difficulty in obtaining spectroscopic redshifts in this
range. We show that the former ``redshift desert'' is now very much open to
observation.Comment: 10 pages, 6 figures, to appear in the Proceedings of the ESO/USM/MPE

Adoption of Integrated Pest Management (IPM) in Chilli (Capsicum annuum L.): A Case Study from Guntur District, Andhra Pradesh
An Integrated Pest Management (IPM) project was implemented in the cropping season 2006-07 in six villages of Guntur District. Survey was conducted in the six villages and all 150 chilli farmers participating in Crop Life India (CLI) sponsored IPM project were treated as a sample for the study. In the case of sucking pests, 56% of the farmers expressed that mites were an important pest. Among the fruit borers, a majority (83.33%) felt that Spodoptera litura was a serious problem and; among diseases, 56% opined die-back to be the major problem. More than twothirds of the respondents adopted all components of IPM, with the exception of bioagents where adoption was just 46%. 44% felt leaf spot was a major disease. Over 80% adopted border crops, trap crops, scouting techniques and mechanical-control measures. All the respondents followed 10-15 day pre-harvest interval of pesticide application as a measure for obtaining quality produce and better price. Problems of post-harvest pests and diseases were not observed in the case of well-dried chillies
