India’s Public Distribution System (PDS) and steps to make food grain distribution system more effective

Image
India’s Public Distribution System (PDS) is the largest distribution network of its kind in the world. PDS was introduced around World War II as a war-time rationing measure. The Public Distribution System (PDS), till 1992, was a general entitlement scheme for all consumers without any specific target. The Revamped Public Distribution System (RPDS) was launched in June 1992. Subsequently, in 1997, the government launched the Targeted Public Distribution System (TPDS), with a focus on the poor. TPDS aims to provide subsidized food and fuel to the poor through a network of ration shops. Food grains, such as rice and wheat that are provided under TPDS are procured from farmers, allocated to states and delivered to the ration shop, where the beneficiary buys his entitlement.  • In September 2013, Parliament enacted the National Food Security Act, 2013. The Act relies largely on the existing TPDS to deliver food grains as legal entitlements to poor households. This marks a shift by mak...

The Deccan Schools (1560-1800 A.D.) Art, Culture, Sculpture & Paintings

Image
Though no pre-Mughal painting from the Deccan are so far known to exist, yet it can safely be presumed that sophisticated schools of painting flourished there, making a significant contribution to the development of the Mughal style in North India. Early centres of painting in the Deccan, during the 16th and 17th centuries were Ahmednagar, Bijapur and Golconda. In the Deccan, painting continued to develop independently of the Mughal style in the beginning. However, later in the 17th and 18th centuries it was increasingly influenced by the Mughal style. 1. AHMEDNAGAR The earliest examples of the Ahmednagar painting are contained in a volume of poems written in praise of Hussain Nizam Shah I of Ahmednagar (1553-1565) and his queen. This manuscript known as the 'Tarif-in-Hussain Shahi and assigned to a period 1565-69 is preserved in the Bharat ltihas Samshodaka Mandala, Poona. One of the illustrations depicts the king sitting on the throne and attended by a number of women. The female...

The Pahari Painting Schools (17th TO 19th Century)

Image
The Pahari region comprises the present State of Himachal Pradesh, some adjoining areas of the Punjab, the area of Union Territory of Jammu in the Jammu and Kashmir State and Garhwal in Uttar Pradesh. The whole of this area was divided into small States ruled by the Rajput princes and were often engaged in welfare. These States were centres of great artistic activity from the latter half of the 17th to nearly the middle of the 19th century. 1 . BASOHLI The earliest centre of painting in the Pahari region was Basohli where under the patronage of Raja Kripal Pal, an artist named Devidasa executed miniatures in the form of the Rasamanjari illustrations in 1694 A.D. There is one more series of the Rasamanjari miniatures painted in the same style and almost of the same period but appears to be in a different hand. The illustrations of the two Rasamanjari series are scattered in a number of Indian and foreign museums. The Basohli style of painting is characterised by vigorous and bold line a...

INSAT-4CR Satellite, ISRO

Image
GSLV-F04 is the fifth flight of India's Geosynchronous Satellite launch Vehicle (GSLV), launched INSAT-4CR satellite, into a Geosynchronous Transfer Orbit (GTO) of 170 km perigee and 35,975 km apogee with an orbital inclination of 21.7 degree with respect to equator on September 2, 2007. Subsequently, the satellite was manoeuvred into geostationary orbit using its own propulsion system. The 49 m tall GSLV, with a lift-off mass of 415 tonne, is a three-stage vehicle with solid, liquid and cryogenic stages. The first stage of GSLV, one of the largest in the world, uses Hydroxyl Terminated Polybutadiene (HTPB) based propellant. The second stage and the four strap-on motors surrounding the first stage use liquid propellant 'Vikas' engine burning UH25 and Nitrogen Tetraoxide. The third stage is a cryogenic stage using liquid Hydrogen as fuel and liquid Oxygen as oxidiser. GSLV employs S-band telemetry and C-band transponders for enabling vehicle performance monitoring, tracking,...

the reservation of seats for women in the institution of local self-government

Image
The 73rd Amendment along with 74th is called a silent revolution. The most revolutionary provision is said to be the reservation of one-third of the seats for women in local bodies (including the number of seats reserved for women belonging to the SCs and STs). Further not less than one-third of the total number of offices of chairpersons in the panchayats at each level shall be reserved for women.  Impact of amendment on patriarchal character of Indian political process:  • But has it really made a considerable impact towards improving the status of women is debatable. In spite of progressive nature of the constitution, traditional social structures that restricted women’s social participation were reinforced in which men hold primary power and pre-dominate roles of political leadership, moral authority, social privilege.  • The reservation of seats in the panchayati raj institutions has enabled women to contest and win elections but lot of structural and procedural chal...

the basic principles of citizens’ charter movement and bring out its importance

It has been recognized the world over that good governance is essential for sustainable development, both economic and social. The three essential aspects emphasized in good governance are transparency, accountability and responsiveness of the administration. The “Citizen’s Charter initiative” is a response to the quest for solving the problems which a citizen encounters, day-in and day-out, while dealing with organisations providing public services.  The concept of Citizen’s Charter enshrines the trust between the service provider and its users. The concept was first articulated and implemented in the United Kingdom by the Conservative Government of John Major in 1991 as a national programme with a simple aim: to continuously improve the quality of public services for the people of the country so that these services respond to the needs and wishes of the users.  Principles: The basic objective of the Citizen’s Charter is to empower the citizen in relation to public service d...
