Public investment and agricultural productivity : a state-wise analysis of foodgrains in India

The main objective of the study is to examine the long-run relationship between public investment and foodgrain productivity across the fifteen major states of India. The analysis is confined to the period, 1974-’75 to 2005-’06. In order to examine the long-run impact of public investment on foodgrain productivity, the study uses Koyck’s Autoregressive Distributed Lag model (ADL). The study observes that the productivity levels are higher in those states where the initial investments were above the national average. The major conclusion of the study is the existence of a positive but lagged effect of public investment on productivity. The lag varies across states; as low as 0.5 years in Gujarat and as high as more than 10 years in Punjab, Haryana and Kerala. The existence of the lag, the study argues, might point to the need for sustained public investment as a means to raise foodgrain productivity in the future.

Municipal Solid Waste Management in Cities - Issues of Basic Rights of People Surrounding Village and Alternatives

The Study is based on the findings of a three weeklong field study conducted in Villappilsala, a village 14 kms away from Thriuvananthapuram City. The waste disposal plant for treating the Municipal Solid Waste generated in the Thiruvanathapuram City is located here. The study focuses on the health and environmental impacts of the functioning of the plant on the local community and addresses the larger question of necessity for scientific and cost effective alternative methods of waste disposal in the city itself. The disposal of Solid Waste has become a problem calling for more attention in the wake of urban development, which is the consequence of more people settling in the cities. The issue of decentralised and scientific disposal of Solid Waste at household level and at the level of small groups of households is emphasised. The central issue thrown up by this study is the poorer sections of the village folk bearing the brunt of the consequences of the profligate consumption and callous waste disposal habits of the upper classes in the citiesMUNICIPAL SOLID WASTE; BASIC RIGHTS; Villappilsala; health and environmental impacts

Taxing powers and developmental role of the Indian states : a study with reference to Kerala

The study analyses whether the growing State Domestic Product (SDP) of Kerala since the latter half of the 1980s, has acted as a larger resource base for the State and finds that it has not. While the inability to fully tap the existing resource potential could be cited as a reason, the paper argues that the main constraint is the limited taxing powers of the States. The Study concludes that the power to tax the services should be devolved from the Centre to the States, lest the fiscal dispossession should affect the sustainability of achievements, which made the development experience of Kerala unique.

Tax devolution and grant distribution to States in India : analysis and roadmap for alternatives

The paper attempts to analyse the impact of devolution of taxes and distribution grants by the Centre to the States in India by taking fourteen major States for the time period 1980-81 to 2006-07. The study focuses on the impact of inter- State distribution of Central grants and taxes. Analysis reveals that formula based tax devolution has been more equalising than grants. Study finds that there is need to explore alternative mechanisms. Keywords: Tax Devolution, Grant Distribution, Horizontal and Vertical Imbalance JEL Classification: JE

Mycobacteria Exploit Host Hyaluronan for Efficient Extracellular Replication

In spite of the importance of hyaluronan in host protection against infectious organisms in the alveolar spaces, its role in mycobacterial infection is unknown. In a previous study, we found that mycobacteria interact with hyaluronan on lung epithelial cells. Here, we have analyzed the role of hyaluronan after mycobacterial infection was established and found that pathogenic mycobacteria can grow by utilizing hyaluronan as a carbon source. Both mouse and human possess 3 kinds of hyaluronan synthases (HAS), designated HAS1, HAS2, and HAS3. Utilizing individual HAS-transfected cells, we show that HAS1 and HAS3 but not HAS2 support growth of mycobacteria. We found that the major hyaluronan synthase expressed in the lung is HAS1, and that its expression was increased after infection with Mycobacterium tuberculosis. Histochemical analysis demonstrated that hyaluronan profoundly accumulated in the granulomatous legion of the lungs in M. tuberculosis-infected mice and rhesus monkeys that died from tuberculosis. We detected hyaluronidase activity in the lysate of mycobacteria and showed that it was critical for hyaluronan-dependent extracellular growth. Finally, we showed that L-Ascorbic acid 6-hexadecanoate, a hyaluronidase inhibitor, suppressed growth of mycobacteria in vivo. Taken together, our data show that pathogenic mycobacteria exploit an intrinsic host-protective molecule, hyaluronan, to grow in the respiratory tract and demonstrate the potential usefulness of hyaluronidase inhibitors against mycobacterial diseases
