  • G20 : Economic Cooperation ahead

    What is the G20 Common Framework?

    Prelims Only | International Relations | Mains Paper 2: Important International Institutions

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Paris Club, G20

    Mains level: Not Much

    Chad has become the first country to officially request a debt restructuring under a new common framework “G20 Common Framework” introduced by China and other Group of 20 countries last year with the help of the Paris Club.

    What is G20 Common Framework?

    • G20 Common Framework is the Common Framework for Debt Treatments beyond the Debt Service Suspension Initiative (DSSI).
    • It was announced in November 2020 to deal with the issue of unsustainable debts faced by various countries as an impact of COVID-19.

    What is the news?

    • This official request of Chad for debt restructuring under the G20 common framework was notified by the International Monetary Fund (IMF).
    • The creditors will now soon begin discussions on the first test of the new framework.
    • The creditors will also ask China and other private-sector creditors to participate as agreed last year.
    • A new four-year programme of Chad worth about $560 million under the Extended Credit and Extended Fund facilities was announced by IMF.
    • Chad is under high debt like many other African countries.

    Significance of the move

    • This is the first time that a country has requested debt restructuring under the framework and the investors will now look at how the framework can work.
    • Participation in China is also a question. Last year, G20 Common Framework brought non-members of the Paris Club- India, China, and Turkey to join the framework.

    Back2Basics: Paris Club

    • Paris Club is a club or group of officials from major creditor countries.
    • It was established in the year 1956.
    • It aims to find sustainable solutions to the difficulties faced by debtor countries in payments.

  • Zoonotic Diseases: Medical Sciences Involved & Preventive Measures

    Why do Viruses mutate?

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Virus mutation

    Mains level: Vaccination challenges for coronavirus

    SARS-CoV-2 variants have emerged independently in several countries, and research published over the past week indicates that the virus is changing more quickly than was once believed.

    Try this PYQ:

    Q.H1N1 virus is sometimes mentioned in the news with reference to which one of the following diseases?

    (a) AIDS

    (b) Bird flu

    (c) Dengue

    (d) Swine flu

    Mutation of Virus

    • Mutation, an alteration in the genetic material (the genome) of a cell of a living organism or of a virus that is more or less permanent and that can be transmitted to the cell’s or the virus’s descendants.
    • Like all life, viruses carry a genetic code in the form of nucleic acids — either DNA or RNA.
    • When cells multiply, the DNA within them replicates as well, to make copies for the new cells.
    • During replication, random errors are introduced into the new DNA, much like spelling errors when we write.
    • While the errors in DNA virus genomes can be corrected by the error-correcting function of cells in which they replicate, there are no enzymes in cells to correct RNA errors.
    • Therefore, RNA viruses accumulate more genetic changes (mutations) than DNA viruses.

    Effect of mutation on the virus

    • Evolution requires not just mutations, but also selection.
    • While most mutations are deleterious to the virus, if some allow a selective advantage — say better infectivity, transmission, or escape from immunity — then the new viruses out-compete the older ones in a population.
    • The mutations can be synonymous (silent) or non-synonymous (non-silent); the latter also changes an amino acid (protein building block) at that position in the coded protein.

    Mutations in COVID

    • As of January 26, about 29,000 infections are attributed to UK variants from 63 countries, many due to local transmission.

    Why is it harmful?

    • Viruses with mutations within the receptor-binding domain (RBD) of the Spike protein have the most potential to evade antibodies that develop as a result of natural infection or vaccination.
    • The RBD binds the cellular receptor allowing the virus to infect cells, and anti-RBD antibodies neutralize the virus.
    • Such mutations were recently found in variant viruses that emerged in the UK, South Africa and Brazil.

    Testing of mutation

    • Indirect tests are done in laboratories to assess if an emerging variant might escape antibodies developed after natural infection or vaccination.
    • Serum (the blood components that contain antibodies) from recovered patients or vaccinated people, and antibodies are known to neutralize the original virus, are tested.
    • Serial dilutions of the serum or antibodies are separately mixed with a fixed amount of the original and variant viruses, and the mixture is added to cells in culture.
    • After a period of incubation, cells are washed and stained. Cells infected and killed by viruses multiplying within them appear as clear zones (plaques) on a dark background.
    • The effectiveness of serum or antibody is expressed as an inhibitory concentration (IC) or plaque reduction neutralisation titer (PRNT) value.
    • The IC50 or PRNT50 value is the reciprocal dilution of serum or antibody that neutralises 50 per cent viruses in the sample.

    India’s response

    • Only the UK variant viruses have so far been reported from India — and that too, in travellers.
    • There is no reported local transmission, but considering its increased infectivity, this is likely to happen.
    • The evidence so far suggests that current vaccines would still protect against the UK variant, even if with reduced efficacy.
    • The evidence at this time, though of concern, does not indicate that current vaccines are failing.
    • But this has to be watched carefully, and all efforts made to limit transmission between people, which drives mutations and the emergence of variants.

  • Right To Privacy

    What is Non-price Competition?

    Prelims Only | Polity | Mains Paper 2: Indian Constitution – historical underpinnings, evolution, features, amendments, significant provisions and basic structure

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Non-price competition

    Mains level: Data privacy issues

    Data privacy can take the form of non-price competition and abuse of dominance can lower privacy protection, a study by the Competition Commission of India (CCI) has said.

    Try this PYQ:

    Q.Right to Privacy is protected as an intrinsic part of Right to Life and Personal Liberty. Which of the following in the Constitution of India correctly and appropriately imply the above statements?

    (a) Article 14 and the provisions under the 42nd Amendment to the Constitution

    (b) Article 17 and the Directive Principles of State Policy in Part IV

    (c) Article 21 and the freedoms guaranteed in Part III

    (d) Article 24 and the provisions under the 44th Amendment to the Constitution

    What is Non-price Competition?

    • Non-price competition is a marketing strategy “in which one firm tries to distinguish its product or service from competing products on the basis of attributes like design and workmanship”.
    • It often occurs in imperfectly competitive markets as it exists between two or more producers that sell goods and services at the same prices but compete through non-price measures.
    • Such measures include marketing schemes and greater quality or any sustainable competitive advantage other than price.

    What is CCI’s observation?

    • The CCI study made observations about non-price factors such as quality of service (QoS), data speeds etc. which are likely to be the new drivers of competitive rivalry between service providers in the telecom sector.
    • CCI noted that an aspect of data in the context of competition in digital communications market is the conflict between allowing access and protecting consumer privacy.

    Privacy at stake

    • Abuse of dominance can take the form of lowering the privacy protection and therefore fall within the ambit of antitrust as low privacy standard implies lack of consumer welfare.
    • Privacy can take the form of non-price competition, said the CCI.
    • On other non-price factors of competition, CCI found that consumers ranked network coverage at the top followed by customer service despite their Privacy.

  • Air Pollution

    What is Nitrogen-Use Efficiency (NUE)?

    Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: NUE, Nitrogen's GHG potential

    Mains level: Nitrogen pollution

    A group of Indian scientists have found a way to improve crops by reducing wastage of nitrogen fertilizers applied to them.

    Try this PYQ:

    Q.Which of the following adds/add nitrogen to the soil?

    1. Excretion of Urea by animals
    2. Burning of coal by man
    3. Death of vegetation

    Select the correct answer using the code given below:

    (a) 1 only

    (b) 2 and 3 only

    (c) 1 and 3 only

    (d) 1, 2, and 3

    Nitrogen-Use Efficiency

    • NUE is calculated as a ratio between nitrogen used and harvest: A higher number denotes low wastage.
    • With the efficiency on the decline, farmers use more fertiliser in the hope of raising yield. This in turn worsens NUE.
    • Crops generally use up 30 per cent of nitrogen fertilizer applied; the rest seeps into the environment, harming health and adding to climate change.
    • Researchers were able to identify phenotypes or visibly identifiable features that determine the efficiency with which cultivated rice varieties (cultivars) use nitrogen.
    • This efficiency is known as nitrogen-use efficiency (NUE).
    • Cereals consume over 69 per cent of nitrogen fertilizers in India; rice tops the list with 37 per cent, followed by wheat (24 per cent).

    Nitrogen Pollution: the reason behind

    • Agriculture leads to 70 per cent of nitrous oxide emissions in India.
    • Of this, 77 per cent is contributed by fertilizers, mostly urea, according to the Indian Nitrogen Assessment published in 2017.
    • This greenhouse gas (GHG) is 300 times more potent than carbon dioxide.
    • It has replaced methane as the second-largest component of GHG emissions from Indian agriculture in the past 15 years.

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: SOFR and various inter-bank rates

    Mains level: Not Much

    State Bank of India (SBI) has executed two inter-bank short term money market deals with pricing linked to SOFR (Secured Overnight Financing Rate).

    Try this PYQ:

    Q.The money multiplier in an economy increases with which one of the following?

    (a) Increase in the cash reserve ratio

    (b) Increase in the banking habit of the population

    (c) Increase in the statutory liquidity ratio

    (d) Increase in the population of the country

    What is SOFR?

    • Secured Overnight Financing Rate (SOFR) is a secured interbank overnight interest rate.
    • It is a replacement for USD LIBOR (London Inter-bank Offered Rate) that may be phased out end-2021.
    • The overnight rate is generally the interest rate that large banks use to borrow and lend from one another in the overnight market.

    Why SOFR?

    • Global regulators decided to move away from the Libor, a vital part of the financial system after it was revealed in 2012 that banks around the world manipulated it.
    • It also didn’t help that volume underlying the benchmark dried up.
    • U.K regulators set the deadline at 2021 for financial firms and investors to transition away from the Libor.

    • Risa is one of the three parts of customary Tripuri female attire, the other two being the Rignai and Rikutu.
    • The Risa, which is essentially a customary hand-woven cloth, is used as headgear, stole, female upper cloth or presented to honour a distinguished recipient.
    • The Rignai is primarily used to cover the lower part of the body and literally translates into ‘to wear’. The Rituku covers the upper half of the body, wrapping it all around.
    • However, it is also used as a ‘chunri’ or a ‘pallu’ of the Indian saree. It is also used to cover the head of newly married Tripuri women.

    Its cultural significance

    • Apart from its beautiful designs, the Risa plays a host of crucial social utilities.
    • Adolescent Tripuri girls are first given Risa to wear when she reaches 12-14 years in an event called Risa Sormani.
    • The event involves prayers to a Lampra god, where her elder women pray for her wellbeing throughout her life.
    • However, it is also used in religious festivals like the Garia Puja, a customary festival of the tribal communities, or as a head turban by male folks during weddings and festivals, as a cummerbund over dhoti or headscarf.
    • The cloth is even used as a makeshift baby carrier on the mother’s back.

    From UPSC perspective, the following things are important:

    Prelims level: 5G technology

    Mains level: 5G technology and its rollout

     

    The Department of Telecommunications (DoT) has sought inputs from telcos and other industry experts on the sale and use of radiofrequency spectrum over the next 10 years, including the 5G bands.

    Try this PYQ:

    Q. In India, which of the following review the independent regulators in sectors like telecommunications, insurance, electricity, etc.?

    1. Ad Hoc Committees set up by the Parliament
    2. Parliamentary Department Related Standing Committees
    3. Finance Commission
    4. Financial Sector Legislative Reforms Commission
    5. NITI Aayog

    (a) 1 and 2

    (b) 1, 3 and 4

    (c) 3, 4 and 5

    (d) 2 and 5

    What is 5G technology?

    • 5G or fifth generation is the latest upgrade in the long-term evolution (LTE) mobile broadband networks.
    • It mainly works in 3 bands, namely low, mid and high-frequency spectrum — all of which have their own uses as well as limitations.

    Three bands of 5G

    • The low band spectrum has shown great promise in terms of coverage and speed of internet and data exchange, the maximum speed is limited to 100 Mbps (Megabits per second).
    • This means that while telcos can use and install it for commercial cellphones users who may not have specific demands for very high-speed internet, the low band spectrum may not be optimal for specialised needs of the industry.
    • The mid-band spectrum, on the other hand, offers higher speeds compared to the low band but has limitations in terms of coverage area and penetration of signals.
    • Telcos and companies, which have taken the lead on 5G, have indicated that this band may be used by industries and specialised factory units for building captive networks that can be moulded into the needs of that particular industry.
    • The high-band spectrum offers the highest speed of all the three bands, but has extremely limited coverage and signal penetration strength.
    • Internet speeds in the high-band spectrum of 5G have been tested to be as high as 20 Gbps (gigabits per second), while, in most cases, the maximum internet data speed in 4G has been recorded at 1 Gbps.

    Where does India stand in the 5G technology race?

    • On par with the global players, India had, in 2018, planned to start 5G services as soon as possible, with an aim to capitalize on the better network speeds and strength that the technology promised.
    • Indian private telecom players have been urging the DoT to lay out a clear road map of spectrum allocation and 5G frequency bands so that they would be able to plan the rollout of their services accordingly.
    • One big hurdle, however, is the lack of flow of cash and adequate capital with some companies due to their AGR dues.

    Global progress on 5G

    • More than governments, global telecom companies have started building 5G networks and rolling it out to their customers on a trial basis.
    • In countries like the US, some companies have taken the lead when it comes to rolling out commercial 5G for their users.
    • A South Korean company, which had started researching on 5G technology way back in 2011, has, on the other hand, take the lead when it comes to building the hardware for 5G networks for several companies.

    Back2Basics: Martian Day/ Sol

    • Coincidentally, the duration of a Martian day aka ‘Sol’ is within a few per cent of that of an Earth day, which has led to the use of analogous time units.
    • A sol is slightly longer than an Earth day. It is approximately 24 hours, 39 minutes, 35 seconds long.
    • A Martian year is approximately 668 sols, equivalent to approximately 687 Earth days.
    • Mars has an axial tilt and a rotation period similar to those of Earth.
    • Thus, it experiences seasons of spring, summer, autumn and winter much like Earth.
