Gini Index

Gini Index

Gini Index Latest News

India has emerged as the world’s fourth most equal society, with a Gini Index of 25.5, outpacing all G7 and G20 nations, according to the World Bank.

About Gini Index

  • The Gini index, also called the Gini coefficient or Gini ratio, determines a nation's level of income inequality by measuring the income distribution or wealth distribution across its population. 
  • The Gini index was developed in 1912 by Italian statistician Corrado Gini.
  • The coefficient of the Gini index ranges from 0 (or 0%) to 1 (or 100%), with 0 representing perfect equality and 1 representing perfect inequality.
    • To offer two hypothetical examples, if a nation were to have absolute income equality, with every person earning the same amount, its Gini score would be 0 (0%). 
    • On the other hand, if one person earned all the income in a nation and the rest earned zero, the Gini coefficient would be 1 (100%). 
  • Mathematically, the Gini coefficient is defined based on the Lorenz curve. 
    • The Lorenz curve plots the percentiles of the population on the graph’s horizontal axis according to income or wealth, whichever is being measured. 
    • The cumulative income or wealth of the population is plotted on the vertical axis.
  • The Gini index is not an absolute measure of a country’s income or wealth. The coefficient only measures the dispersion of income or wealth within a population.
  • India’s Gini Index:
    • According to the recent World Bank report, India’s Gini Index stands at 25.5, placing it as the fourth most equal country globally, behind only the Slovak Republic, Slovenia, and Belarus. 
    • This performance not only surpasses regional peers like China, which holds a Gini score of 35.7, but also positions India ahead of every G7 and G20 nation in terms of income equality.
    • It marks a steady improvement from a Gini score of 28.8 in 2011 to 25.5 in 2022, signalling meaningful gains in bridging income gaps over the past decade.

Onge Tribe

Onge Tribe Latest News

The Andaman and Nicobar Islands administration recently set up a Van Dhan Vikas Kendra for the Onge tribe at Dugong Creek under Pradhan Mantri Janjati Adivasi Nyay Maha Abhiyan to make them self-sustainable through coconut-based products.

About Onge Tribe

  • Onges are one of the most primitive tribes in India. They belong to the Negrito racial stock.
  • They are inhabiting Little Andaman Island, the most southerly island in the Andaman archipelago.
  • They are semi-nomadic tribes and fully dependent on the food provided by nature. 
  • The religion of the Onges is simple animism. Neither ceremonial worship nor any kind of propitiation is practiced by them. They believe in different classes of spirits-spirits of the wood, the sea, disease, storm, and ancestors. 
  • The Onge speak their own language, which has no script. 
  • The colour of the teeth has a unique interpretation among Onges, who consider pearly white teeth a symbol of death. They continue to chew the bark to impart a red colour to their teeth.
  • They decorate their bodies and their faces with white and ochre clay. On special occasions, they place a greater emphasis on body ornamentation.
  • Until the 1940s, the Onge were the sole permanent inhabitants of Goubalambabey (the Onge name for Little Andaman).
  • They now share the 732 sq km island with around 17,000 settlers from India, Bangladesh, and the Nicobar Islands.
  • The Onge population was also decimated following contact with British colonists and Indian settlers; it fell from 670 in 1900 to only 96 members by the early 2000s.
  • In 1976, the Onge were settled in order to have ‘the basic facilities for hygienic living and protection against elements of nature’.
  • They now live in a reserve in Dugong Creek (Little Andaman) that is a fraction of the size of their original territory.
  • The Onge tribe is also one of the world’s least prolific and infertile communities. Infertility affects somewhat more than 40% of married couples.

The Kerala Health Minister recently confirmed that 425 individuals have been placed on the Nipah virus contact list across the state.

About Nipah Virus

  • Nipah virus (NiV) is an emerging zoonotic virus that can be transmitted to humans from animals (both wild and domestic). 
  • It can also be transmitted through contaminated food or directly from person-to-person.
  • Fruit bats of the Pteropodidae family are the natural hosts of Nipah virus. 
  • NiV infection can be asymptomatic or mild (subclinical), but it also causes acute respiratory illness and fatal encephalitis. 
  • Symptoms
    • Initial symptoms of NiV infection may include fever, headache, myalgia (muscle pain), nausea, vomiting, sore throat, cough, and/or respiratory discomfort.
    • Acute encephalitis might develop with the following symptoms: dizziness, drowsiness, altered state of consciousness, and any other indicative neurological signs. 
    • In severe cases, encephalitis and seizures occur and may lead to coma within 24–48 hours. 
    • Progression to encephalitis indicates a poor prognosis, with death within a median of six days after the onset of symptoms.
  • The case fatality rate is estimated between 40–75% or higher, and it varies depending on the specific NiV strain, access to and quality of healthcare, or the severity of illness. 
  • Treatment: There are no specifically approved treatments or vaccines available for NiV infection, either for people or animals.  
  • So far, NiV outbreaks have only been described in Asia. 
    • The first reported outbreak occurred in 1998–1999 and involved pig farmers in the village of Sungai Nipah (Malaysia). 
    • Since then, sporadic outbreaks have been documented in Bangladesh, India, the Philippines, and Singapore.

Alluri Sitaram Raju

Alluri Sitaram Raju

Alluri Sitaram Raju Latest News

The defence Minister recently said that the government has emulated legendary revolutionary Alluri Sitarama Raju’s ideals in making a tribal woman, Draupadi Murmu, as the President of India.

About Alluri Sitaram Raju

  • He was an Indian revolutionary who waged an armed campaign against British colonial rule in India. 
  • Born to a Telugu-speaking family on 4th July 1897 at Bhimavaram in present-day Andhra Pradesh, he became involved in opposing the British in response to the 1882 Madras Forest Act, which effectively restricted the free movement of Adivasis (tribal communities) in their forest habitats and prevented them from practicing a traditional form of agriculture known as ‘Podu’. 
  • Rising discontent towards the British led to the Rampa Rebellion of 1922, in which he played a major part as a leader. 
  • Mustering a force combined of Adivasis, farmers and sympathizers to their cause, he engaged in guerilla campaigns against the British colonial authorities in the border regions of the Madras Presidency part of the districts of East Godavari and Visakhapatnam (now part of Alluri Sitharama Raju district). 
  • He was nicknamed "Manyam Veerudu" (Hero of the Jungle) by local villagers for his heroic exploits. 
  • Alluri adopted aspects from the Non-cooperation movement, such as promoting temperance, and the boycott of colonial courts in favour of local justice, administered by panchayat courts, to attract people's support. 
  • Although the movement died out in early 1922, it had reached the plains area by then, as he was involved in the propagation of some of its methods among the hill people, to raise their political consciousness, and desire for change. 
  • These actions caused him to be put under the surveillance of police from around February of that year, although the fact that he was using them as a camouflage to foment armed uprising seems to have not been recognized by either the movement or the political leadership of the British.
  • After putting up a massive effort for nearly two years, the British finally managed to capture Alluri in the forests of Chintapalle; he was then tied to a tree and executed by shooting on 7 May 1924 in the village of Koyyuru. 
  • A tomb of him currently lies in the village of Krishnadevipeta, near Visakhapatnam. 
  • The heroic efforts of young Alluri in fighting an all-out war without any state powers, against one of the most powerful empires have been recognised by all.
  • The British Government grudgingly acknowledged him as a powerful tactician of the Guerrilla warfare which lasted for nearly two years, the fact that they had to spend over 40 lakhs in those days to defeat him.

Very Massive Stars

Very Massive Stars

Very Massive Stars Latest News

 A new study suggests that ‘Very massive stars’ or ‘very luminous stars’ may be emitting a significantly higher amount of material during their lifespan and the immensity of these materials could be much higher than previously thought.

About Very Massive Stars

  • These are those stars that have over 100 times the mass of the Sun.
  • They have a much higher mass than the Sun, they use their nuclear fuel at a much higher rate, making their average lifespan only a few million years.
  • Once their nuclear fuel is exhausted, very luminous stars collapse to form black holes.
  • These stars produce stellar wind that is powerful enough to blow their own outer layer into space. 

Importance of Very Massive Stars

  • These stars, despite their short lifespan, still influence the region around them.
  • Their powerful stellar winds can push newly formed elements into their surroundings. While most form new stars, elements key to life, such as carbon and oxygen, are also emitted.
  • In spite of their distance from our Earth, they still bear an influence on it.
  • These stars can be considered the predecessor to black holes. This occasionally leads to black hole binaries, where two black holes orbit around each other. These cause gravitational waves, which we then detect on Earth.

  • It is a rhythmic cycle used in North Indian classical music, particularly in Hindustani classical music.
  • The name “Chautal” means “four claps,” referring to its vibhag or division structure.
  • One school of thought contends that it consists of four vibhags of 4, 4, 2, and 2 matras respectively.
  • There is another school which suggests that the structure of Chautal is the same as Ektal.  Therefore, it would be viewed as six vibhags of two matras each.
  • It is strongly linked to the pakhawaj tradition; this has profound practical and theoretical implications. 
  • It is performed in a very heavy, powerful manner which is in sharp contrast to the more delicate style of the tabla.
