    Role of Parliamentary Committees

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Parliamentary Committees

    Mains level: Legislative consultation

    Central idea: This article discusses the importance and functions of parliamentary committees in India.

    Why in news?

    • As little as 25% of the Bills introduced were referred to committees in the 16th Lok Sabha, as compared to 71% and 60% in the 15th and 14th Lok Sabha respectively.
    • This represents a declining trend of national legislation being subjected to expert scrutiny.

    What is a Parliamentary Committee?

    • A committee appointed or elected by the House or nominated by the Speaker that works under the direction of the Speaker and presents its report to the House or the Speaker.
    • Two kinds of committees: Standing Committees and Ad hoc Committees.

    (1) Standing Committees

    • Permanent and regular committees constituted from time to time in pursuance of the provisions of an Act of Parliament or Rules of Procedure and Conduct of Business in Lok Sabha.
    • The work of these Committees is of continuous nature.
    • Examples include the Financial Committees and DRSCs.

    (2) Ad hoc Committees

    • Appointed for a specific purpose and cease to exist when they finish the task assigned to them and submit a report.
    • The principal Ad hoc Committees are the Select and Joint Committees on Bills.
    • Examples include the Railway Convention Committee and Joint Committee on Food Management in Parliament House Complex.

    Why need Parliamentary Committee?

    • Parliament scrutinizes legislative proposals (Bills) in two ways: discussion on the floor of the two Houses and referring the Bill to a parliamentary committee.
    • Since Parliament meets for 70 to 80 days in a year, there is not enough time to discuss every Bill in detail on the floor of the House.

    Role of the committee in the passage of a Bill

    • The debate in the house is mostly political and does not go into the technical details of a legislative proposal.
    • Referring a Bill to a parliamentary committee takes care of the legislative infirmity of debate on the floor of the House.
    • However, referring Bills to parliamentary committees is not mandatory.

    What is a Select Committee?

    • India’s Parliament has multiple types of committees.
    • Departmentally related Standing Committees focus on the working of different ministries.
    • Each committee has 31 MPs, 21 from Lok Sabha and 10 from Rajya Sabha.
    • The main purpose is to ensure the accountability of Government to Parliament through a more detailed consideration of measures in these committees.

    When does a committee examine a Bill?

    • Bills can reach a committee through a recommendation by the minister piloting the Bill or the presiding officer of the House.

    What happens when a Bill goes to a Committee?

    • The committee undertakes a detailed examination of the Bill, inviting comments and suggestions from experts, stakeholders and citizens.
    • The government also appears before the committee to present its viewpoint.
    • The committee’s report makes suggestions for strengthening the Bill.
    • While the committee is deliberating on a Bill, there is a pause in its legislative journey.
    • The Bill can only progress in Parliament after the committee has submitted its report.

    What happens after the report?

    • The report of the committee is of a recommendatory nature.
    • The government can choose to accept or reject its recommendations.
    • Select Committees and JPCs have an added advantage of including their version of the Bill in the report.
    • The minister in charge of that particular Bill can move for the committee’s version of the Bill to be discussed and passed in the House.

    Importance of these Committees

    • Parliamentary committees analyze the impact that a specific piece of legislation may have on governance indicators.
    • It recommends the government to take an ‘Action Taken’ report for the House to judge the progress made on the suggestions of the committee.
    • Though committee reports aren’t binding on the government, it helps the legislature ensure oversight of the executive.

    What is Large Hadron Collider (LHC)?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Large Hadron Collider (LHC)

    Mains level: Not Much

    hadron

    Central idea: The article provides an overview of the LHC, its construction, how it works, and what it has discovered. It also discusses the future of the LHC, including plans to upgrade it and build a bigger version.

    Large Hadron Collider (LHC)

    • The Large Hadron Collider (LHC) is the world’s largest science experiment built by the European Organisation for Nuclear Research (CERN).
    • It is a collider that smashes two beams of particles in opposite directions and these particles are hadrons.
    • The LHC is on the energy frontier of physics research, conducting experiments with highly energized particles.
    • Currently, the LHC is being warmed up for its third season of operations following upgrades that have made it more sensitive and accurate.

    How does the LHC work?

    • Hadrons are subatomic particles made up of smaller particles, and the LHC typically uses protons.
    • Protons are energized by accelerating them through a narrow circular pipe that is 27 km long.
    • The pipe encircles two D-shaped magnetic fields created by almost 9,600 magnets.
    • Protons are accelerated through the beam pipe by rapidly switching the direction of the magnetic field.
    • Eventually, protons move at 99.999999% of the speed of light, according to the special theory of relativity.

    What happens when particles are smashed?

    • When two antiparallel beams of energized protons collide head-on, the energy at the point of collision is equal to the sum of the energy carried by the two beams.
    • The highest centre-of-mass collision energy the LHC has achieved so far is 13.6 TeV.
    • At the moment of collision, there is chaos, and energy coalesces into different subatomic particles under the guidance of the fundamental forces of nature.
    • Different particles take shape depending on the amount and flavour of energy available.

    What has the LHC found so far?

    • The LHC consists of nine detectors, and they study particle interactions in different ways.
    • The ATLAS and CMS detectors discovered the Higgs boson in 2012 and confirmed their findings in 2013.
    • Using the data from collisions, scientists have tested the predictions of the Standard Model of particle physics, observed exotic particles, and pieced together information about extreme natural conditions.

    What is the LHC’s future?

    • The LHC has not been able to find ‘new physics’ that can explain the nature of dark matter or why gravity is such a weak force.
    • One way forward is to improve the LHC’s luminosity by 10x by 2027 through upgrades.
    • Another idea is to build a bigger and more powerful version of the LHC, based on the hypothesis that it can find ‘new physics’ at even higher energies.
    • Physicists are divided on whether to invest in building a bigger machine or less expensive experiments with guaranteed results.

    B2BASICS

    What is Hadron?

    • Hadron is any member of a class of subatomic particles that are built from quarks and thus react through the agency of the strong force. The hadrons embrace mesons, baryons (e.g., protons, neutrons, and sigma particles), and their many resonances.

    CERN

    • European Organisation for Nuclear Research (CERN) is the world’s largest nuclear and particle physics laboratory.
    • CERN is based in Geneva on the French-Swiss border. It has 23 member states.
    • India in 2016 became an associate member of the CERN. Indian scientists have played a significant role in the ALICE experiment, which is a dedicated experiment for search and study of Quark Gluon Plasma (QGP).

    LIGO-India: India’s Node in Global Universe Probe

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: LIGO

    Mains level: Gravitational waves study

    ligo

    India has given the final approval to build its biggest scientific facility, Laser Interferometer Gravitational-Wave Observatory (LIGO), in the Hingoli district of Maharashtra. The facility will join the global project to detect and study gravitational waves.

    Gravitation and General Theory of Relativity

    • Newton’s law of gravitation, proposed by Sir Isaac Newton in the 17th century, explains that the force that makes an object fall to the ground is also responsible for making heavenly bodies go around in their orbits.
    • However, the theory did not explain the existence of an attractive force between any two bodies or the instantaneous propagation of the gravitational force over large distances.
    • In 1915, Albert Einstein proposed the General Theory of Relativity, which altered our understanding of gravitation. Einstein proposed that space-time interacted with matter, was influenced by it, and in turn, and influenced events.
    • The curvature in space-time produced by matter was the reason other smaller bodies in the vicinity felt the gravitational pull.
    • General Relativity also predicted that moving objects would generate gravitational waves in space-time.

    What is LIGO?

    What is it?

    Laser Interferometer Gravitational-Wave Observatory (LIGO)
    Purpose Detect and study gravitational waves
    Cause Ripples in spacetime caused by violent and energetic events in the universe
    Location Livingston, Louisiana and Hanford, Washington
    Detector Michelson interferometer
    Function Measure changes in length caused by passing gravitational waves
    Benefits Improving our understanding of the universe and its origins
    Discovery Detected gravitational waves for the first time in 2015
    Significance Confirmed a prediction made by Albert Einstein’s theory of general relativity
    Field Gravitational wave astronomy
    Discoveries Many exciting discoveries about the nature of the universe

    About LIGO-India

    • LIGO-India will be the fifth node of this international network of gravitational wave observatories, and possibly the last.
    • The instrument is so sensitive that it can easily get influenced by events like earthquakes, landslides, or even the movement of trucks, and produce a false reading.
    • That is why multiple observatories are needed to revalidate the signals.
    • India’s involvement in LIGO is crucial to demonstrating its intent and capability to pull-off complex science projects independently.

    Significance

    • The detection and study of gravitational waves could help in understanding the universe’s structure, the origin of the universe, and the functioning of black holes.
    • The LIGO project also has huge spin-off benefits for India’s science and technology sector.

    Physicists discover new Uranium Isotope

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Uranium isotopes, Radioactivity

    Mains level: NA

    uranium

    Physicists in Japan have discovered a new isotope of uranium, with atomic number 92 and mass number 241.

    Uranium

    • Uranium is a naturally occurring chemical element with the symbol U and atomic number 92.
    • It is a heavy metal that is radioactive and found in small quantities in rocks and soils worldwide.
    • Uranium has several isotopes, which are atoms that have the same number of protons but different numbers of neutrons.

    Isotopes of Uranium

    The most common isotopes of uranium are uranium-238 and uranium-235.

    1. Uranium-238: It is the most abundant isotope of uranium, accounting for over 99% of natural uranium. It has 92 protons and 146 neutrons in its nucleus. It is not fissile, which means it cannot sustain a nuclear chain reaction. However, it is fertile, which means it can absorb neutrons and undergo radioactive decay to produce other isotopes such as plutonium-239, which is fissile.
    2. Uranium-235: It is the second most abundant isotope of uranium, accounting for less than 1% of natural uranium. It has 92 protons and 143 neutrons in its nucleus. Unlike uranium-238, it is fissile, which means it can sustain a nuclear chain reaction. It is used as fuel in nuclear reactors and as the primary material for nuclear weapons.

    How are isotopes created?

    • Isotopes can be created through natural processes or artificial processes in a laboratory.
    • Isotopes are created through natural processes such as radioactive decay, cosmic ray interactions, and nuclear fusion reactions in stars.
    • For example, carbon-14 is created in the Earth’s upper atmosphere when cosmic rays interact with nitrogen atoms.
    • Isotopes can also be created artificially through nuclear reactions.
    • This involves bombarding atoms with particles such as protons, neutrons, or alpha particles, which can change the number of protons and/or neutrons in the nucleus.

    How uranium-241 was found?

    • To find uranium-241, the researchers accelerated uranium-238 nuclei into plutonium-198 nuclei using the KEK Isotope Separation System (KISS).
    • In a process called multinucleon transfer, the two isotopes exchanged protons and neutrons, resulting in nuclear fragments with different isotopes.
    • The researchers identified uranium-241 and measured the mass of its nucleus using time-of-flight mass spectrometry.
    • Theoretical calculations suggest that uranium-241 could have a half-life of 40 minutes.

    Significance of the discovery

    • The discovery is significant because it refines our understanding of nuclear physics, particularly the shapes of large nuclei of heavy elements and how often they occur.
    • This information helps physicists to design models for nuclear power plants and exploding stars.

    Also, what are Magic numbers?

    • There is a particular interest in ‘magic number’ nuclei, which contain a certain number of protons or neutrons that result in a highly stable nucleus.
    • Lead (82 protons) is the heaviest known ‘magic’ nucleus, and physicists have been trying to find the next element with magic numbers.
    • The researchers hope to extend their systematic mass measurements towards many neutron-rich isotopes, at least to neutron number 152, where a new ‘magic number’ is expected.

    Conclusion

    • The discovery of the new neutron-rich uranium isotope is a major breakthrough in nuclear physics, as it provides essential information for understanding the behavior of heavy elements.
    • The researchers’ aim to extend their measurements to other neutron-rich isotopes reflects their commitment to exploring the frontiers of nuclear science and to improve our understanding of the universe.
    • Discovering new magic number nuclei through these measurements could have practical applications in designing safer and more efficient nuclear power plants and understanding the properties of exploding stars.

    Prelims level: TEMPO Mission

    Mains level: Air Pollution monitoring

    tempo

    SpaceX Falcon 9 rocket successfully launched carrying a new NASA device named Tropospheric Emissions Monitoring of Pollution (TEMPO) designed to monitor air pollutants and their emission sources across North America from space more comprehensively than ever before.

    What is TEMPO?

    • TEMPO is an instrument developed by NASA, which will enable scientists to monitor air pollutants and their emission sources from space, down to the neighbourhood level.
    • This instrument will measure pollution and air quality across greater North America on an hourly basis during the daytime.

    TEMPO’s special features

    • TEMPO is unique because it will be hosted on an Intelsat communications satellite in geostationary orbit, about 22,236 miles (35,786 km) above the equator.
    • This will allow the instrument to match the rotation of the Earth, meaning it will stay over the same location (North America) at all times.
    • It will be able to measure atmospheric pollution down to a spatial resolution of 4 square miles (10 square km), or neighbourhood level.

    Applications of TEMPO

    • TEMPO will have multiple applications from measuring levels of various pollutants to providing air quality forecasts and helping the development of emission-control strategies.
    • The data will be used by the US Environmental Protection Agency (EPA), the National Oceanic and Atmospheric Administration (NOAA), and other agencies responsible for tackling atmospheric pollution.

    Importance of the mission

    • According to the American Lung Association, more than 40% of the US population, 137 million people, live in places with unhealthy levels of particle pollution or ozone, and air pollution is blamed for some 60,000 premature deaths a year.
    • TEMPO will track pollutants like nitrogen dioxide, produced from the combustion of fossil fuels, formaldehyde, and ozone.

    Coverage For age groups 3 to 18 years

    Seeks feedback from various stakeholders

    National Steering Committee Set up by the Ministry to undertake and develop NCFs under the chairmanship of K. Kasturirangan.

     

    Salient features of NCF

    (1) Values and Roots

    • A key part of the document is the inclusion of values and its “rootedness” in India.
    • The pre-draft says that the framework is deeply rooted in India in content and learning of languages, in the pedagogical approaches including tools and resources, and in philosophical basis — in the aims and in the epistemic approach.
    • The document further says that it leans towards making students acquainted with true sources of knowledge, which have been a philosophical preoccupation of ancient Indians.
    • These sources focus on six pramanas: pratyaksa, anumana, upamana, arthapatti, anupalabdhi, and sabda.

     

    Six Pramanas

    1.      Pratyaksha: Interpreted as perception through the five senses

    2.      Anumana: Uses inferences to come to new conclusions

    3.      Upamana: Knowing through analogy and comparison

    4.      Arthapatti: Involves knowing through circumstantial implication

    5.      Anupalabdhi: Includes perception of non-existence

    6.      Sabda: Something an individual can only directly know a fraction of all reality through direct experience and inference but must rely on other experts was acknowledged thousands of years ago

     

    (2) Moral Development

    • A part of the document focuses on the moral development of a child through panchakosha vikas or five-fold development.
    • The pre-draft recommends developing moral values for the child through a balanced diet, traditional games, yoga asanas, as well as a wide variety of stories, songs, lullabies, poems, and prayers to develop a love for cultural context.

    (3) Curriculum revamp

    • The pre-draft says that for Grade 10 certification, students will have to take two essential courses from humanities, maths and computing, vocational education, physical education, arts education, social science, science, and interdisciplinary areas.
    • In Grade 11 and 12, students will be offered choice-based courses in the same disciplines for more rigorous engagement.
    • Arts education will include music, dance, theatre, sculpture, painting, set design, scriptwriting, while interdisciplinary areas will include knowledge of India, traditions, and practices of Indian knowledge systems.
    • For Class 11 and 12, the document states that “Modular Board Exams will be offered as opposed to a single exam at the end of the year, and the final result will be based on the cumulative result of each exam.”
    • The framework of the social science curriculum emphasizes understanding and appreciating the feeling of Indianess, ‘bhartiyata,’ by valuing the rich cultural heritage and tradition of the country.
    • It also stresses on identifying and explaining important phases of the Indian national movement against British rule, with special reference to Gandhian and other subaltern movements.

    (4) Social Science Curriculum

    • The pre-draft emphasizes understanding and appreciating the feeling of Indianess, “bhartiyata,” by valuing the rich cultural heritage and tradition of the country.
    • The pre-draft also stresses on identifying and explaining important phases of the Indian national movement against British rule, with special reference to Gandhian and other subaltern movements.
    • It also recommends teaching concepts of Buddhism, Jainism, and Vedic and Confucian philosophies.

    (5) Follow-up processes

    • As a follow-up to the National Education Policy 2020, development of four National Curriculum Frameworks — NCF for School Education, NCF for Early Childhood Care and Education, NCF for Teacher Education, and NCF for Adult Education — have been initiated.
    • The National Steering Committee under the chairmanship of K. Kasturirangan was set up by the Ministry to undertake and develop NCFs.

    Controversy over curriculum revamp

    • The latest round of textbook rationalisation has resulted in some of the most sweeping changes in the curriculum since the NDA government came to power.
    • These changes include removing all references to the 2002 Gujarat riots, reducing content related to the Mughal era and the caste system, and dropping chapters on protests and social movements.
    • Many of these changes are seen as ‘political’, however, their earlier introduction into curriculum was also a political move.

    The furore over Mughal History

    • While some of the content on the Delhi Sultanate and the Mughal Empire has indeed been removed from the history textbook for Class 7, the Mughals have not entirely disappeared.
    • For instance, the chapter ‘The Mughal Empire’ in the Class 7 history textbook, Our Pasts – II, has undergone deletions — including a two-page table on the milestones and achievements of the reigns of the emperors Babur, Humayun, Akbar, Jahangir, Shah Jahan, and Aurangzeb.
    • However, the chapter itself has not been removed.
    • Students of Class 7 will continue to learn about the Mughals, though in lesser detail.

    Significance

    • School textbooks have always been seen as playing a crucial role in shaping national narratives, and as a tool for cultivating a desired national identity.
    • NCERT textbooks are read by more than 5 crore students in 18 states around the country, who are seen by political parties as a large captive audience with impressionable minds.
    • It’s not just school students either — candidates preparing for competitive exams such as the Civil Services Examination, SSC, JEE, and NEET, also rely on these textbooks.

    Principles of Natural Justice and Proportionality

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Natural Justice, Proportionality

    Mains level: Freedom of press

    justice

    Central idea

    • The Supreme Court lifted a broadcasting ban on a Malayalam news channel ‘MediaOne’.
    • The court blasted the government for silencing voices in the media who “speak truth to power” by branding them as “anti-establishment”.

    A quick recap of the case

    • The Ministry of Information and Broadcasting (MIB) has earlier refused to renew broadcast license of a Malayalam news channel.
    • The Ministry of Home Affairs had declined to grant security clearance to the channel’s promoters citing alleged links between radical groups.
    • Hence the news agency approached Kerala High Court, which upheld the ban on February 9, 2022
    • The Supreme Court granted temporary relief and allowed it to resume operations.

    Supreme Court’s ruling

    • The Supreme Court set aside earlier ban orders and upheld the channel’s appeal on two procedural grounds, namely
    1. Principles of natural justice and
    2. Proportionality

    Articles invoked in the judgment

    • The Court stated that the burden shifts on the Centre to prove that the procedure followed was reasonable and in compliance with the requirements of Articles 14 and 21 of the Constitution.
    • The Court used the standard of proportionality to test the reasonableness of the procedure in the present case and assessed the validity of public interest immunity claims based on the “structured proportionality standard”.
    • The Court found that the reasons for denying security clearance to the channel were not legitimate purposes for the restriction of the right of freedom of speech protected under Article 19(1)(a) of the Constitution.

    Key concepts involved

    (1) Principles of natural justice

    • The principles of natural justice are a set of procedural rules that ensure fairness and justice in administrative and legal proceedings.
    • These principles are based on the fundamental idea that everyone is entitled to a fair hearing, and they are aimed at preventing arbitrary or biased decisions by decision-makers.
    • The SC bench allowed the challenge to the MHA order and judgment of the High Court on account of the principles of natural justice constitutionalized by its judgment in its 1978 ruling in “Maneka Gandhi vs Union of India”
    • Actions which violate procedural guarantees can be struck down even if non-compliance does not prejudice the outcome of the case.

    (2) Proportionality

    • The principle requires that the decision or action must be proportionate to the objective it seeks to achieve.
    • In other words, the means employed to achieve the objective must be no more than necessary to achieve it, and the harm caused by the decision or action must not be excessive in relation to the benefit gained.
    • The validity of the claim of involvement of national security considerations must be assessed on the test of whether there is material to conclude that the non-disclosure of information is in the interest of national security.
    • Courts can assess the validity of public interest immunity claims based on the “structured proportionality standard”, said the SC.
    • The SC observed that sealed cover proceedings infringe the principles natural justice and open justice.

    Conclusion

    • The Court’s ruling has been welcomed by media organizations and civil society groups as a victory for freedom of speech and expression
    • The Court observed that the duty to act fairly derived from common law is not exhaustively defined in a set of concrete principles, and the concept of natural justice “cannot be put into a ‘straitjacket formula’.
    • The ruling has been hailed as a victory for freedom of speech and expression, and a blow to attempts to stifle dissent and critical voices in the media.

    From UPSC perspective, the following things are important:

    Prelims level: Dibang WLS, Idu Mishmi

    Mains level: Not Much

    mishmi

    Central idea

    • The National Tiger Conservation Authority has proposed to notify Dibang Wildlife Sanctuary in Arunachal Pradesh as a tiger reserve, causing concerns among the Idu Mishmi community.
    • The Idu Mishmi community has a unique cultural relationship with the forest, particularly with tigers.
    • This article explains who the Idu Mishmis are, their relationship with the forest, the move to propose a tiger reserve, and the community’s resistance.

    Who are the Idu Mishmis?

    • The Idu Mishmi community is a sub-tribe of the larger Mishmi group, primarily living in the Mishmi Hills bordering Tibet in Arunachal Pradesh.
    • The tribe has strong ties with the flora and fauna of the region, particularly tigers, which are considered their “elder brothers” in their mythology.
    • Despite traditional hunting practices, the tribe follows a belief system of myths and taboos that restrict them from hunting many animals, including a complete prohibition on killing tigers.
    • This belief system has led to a unique model of wildlife conservation, according to anthropologists and researchers.

    Overturning Dibang WLS into Tiger Reserve

    • Plans to declare Dibang Wildlife Sanctuary as a tiger reserve have been ongoing for a while now.
    • The sanctuary, home to rare Mishmi takin, musk deer, goral, clouded leopards, snow leopards, and tigers, was notified in 1998.
    • The Wildlife Institute of India carried out a survey in 2014 to determine the presence of tigers in the area based on photographic evidence via camera trapping.
    • The study recorded the presence of tigers in the highest reaches of the Mishmi Hills, forming the basis of the proposal to declare the sanctuary as a tiger reserve.

    Why are the Idu Mishmis resisting the move?

    • The community’s access to the Dibang forests has not been impacted as a wildlife sanctuary, but many believe a tiger reserve would increasingly restrict access.
    • The upgrade to a tiger reserve would feature stricter security measures, such as a ‘Special Tiger Protection Force,’ which would hinder the community’s access to their forest lands.
    • The community has declared part of its forest land as a ‘Community Conserved Area,’ governed entirely by local populations, where they ban hunting, felling trees, and implement other conservation measures.
    • The community alleges that the Dibang WLS was created without their consent or knowledge.
