Learning is the process of acquiring new understanding, knowledge, behaviors, skills, values, attitudes, and preferences. The ability to learn is possessed by humans, animals, and some machines; there is also evidence for some kind of learning in certain plants.

Classical Economics

Classical economics relates to the school of thought of economics that originated in Britain during the late 18th and early 19th centuries. The classical economists believed in the existence of full employment in the economy. It is believed that ‘The Wealth of Nations’ by Adam Smith published in 1776 marked the beginning of classical economics. J.B. Say, Alfred Marshall, A.C. Pigou are some of the famous classical economists.
This school of economics focused on the theory called the ‘invisible hand‘ being the highlight at the beginning stages of domestic and international supply and demand. They assumed the economy to be laissez faire capitalist. It was a closed economy with no foreign trade. Labour was a homogenous and wages were flexible. It assumed the economy to be in the long run.

The Classical school of thought is based on the Law of Markets given by J.B. Say. According to that law “supply creates it’s own demand“. Therefore there can never be the problem of overproduction or unemployment in the economy as whatever is produced is consumed. Unemployment may occur only in the short run and in the long run, economy tends towards full employment.
The Classical economists also believed in wage price flexibility. This concept was given by A.C. Pigou. It was basically the formulation of Say’s Law in terms of labour market. According to this, whenever there is unemployment in the economy, a general cut in money wages will restore full employment condition. Unemployment is a consequence of the rigid wage structure.
They also believed in the existence of equilibrium in the goods market. It is achieved when savings is equal to investment. This equality is usually brought by the mechanism of interest rate. Similarly, the money market is in equilibrium when the demand for money is equal to the supply of money. This concept was explained in the Quantity Theory of Money.

The Fall of Classical Economics:

During the time of The Great Depression i.e. 1929-1930’s, the classical theory failed to be applicable. It failed to solve the problem of depression that plagued for about 43 months. Keynes criticized the classical theory on several grounds.
First and foremost was the classical assumption of full employment equilibrium. Keynes considered it as unrealistic and argued that the situation in the capitalist economy is underemployment and full employment is a special case. He refuted Say’s law of market and stated that it was demand that created supply. He was also against the idea of laissez faire. He believed that self adjustment was not possible in a capitalist system and this was responsible for the Great Depression. He advocated state intervention within the economy through monetary and fiscal measures.
The wage price flexibility was also heavily criticised. In the modern world, where workers have trade unions, any cuts in wages will lead to strikes and industrial unrest. Keynes also stressed that equality between savings and investment was not brought by rate of interest but instead by the level of income and marginal efficiency of capital.
Lastly, the long run analysis of Classical economy was refuted on the grounds of inapplicability. Since it operated in the long run, it is incapable of solving present day economic problems.

Understanding Luminous Pollution.

 

Many of us are taking steps to reduce carbon footprints. We responsibly recycle glass, metal, paper, plastic waste each week. However, unknowingly we are contributing to carbon emissions through light pollution which intrudes the delicate ecosystem. Light pollution in many countries is neglected and not regulated. 

The excessive, misdirected, or unnecessary use of artificial outdoor lighting is known as Light pollution a.k.a Luminous pollution, or Photopollution. Light pollution alters the color and contrast of the nighttime sky, natural starlight, and disrupts the circadian rhythms, which affects the environment, inhabitants, and astronomy research.

As countries are developing, the need for artificial outdoor lighting has also increased and light pollution has spread into suburban and rural areas. 

Types of light pollution:-

1) Light Trespass

2) Glare

3) Sky Glow

4) Light Clutter

What are the causes of light pollution?

Poorly designed residential, commercial and industrial lights contribute significantly to luminous pollution. Also, the use of unnecessary outdoor artificial lights contributes to luminous pollution. Approximately about 30℅ of light is wasted due to poorly designed artificial outdoor lights. 

Let’s have a look at the effects of light pollution.

As mentioned above, light pollution has effects on our environment and its inhabitants, and also on astrology. Mentioned below are some of the known effects of light pollution:-

Effect on the environment:                Excessive nighttime lighting releases more than 12 million tons of carbon dioxide every year into the atmosphere, which would take around 702 million trees to absorb. 

Luminous pollution also increases air pollution by resisting a natural occurring radical that cleans the air at night, called Nitrate radical. 

Effect on wildlife:                                    Light pollution can alter the feeding, mating, sleeping, and migration cycles of the entire wildlife. Wildlife can also feel the disorientation of time due to excessive light pollution.

Effect on energy:                            According to a study by IDA( International Dark-Sky Association) in 2007,  it is estimated that about 30% of the light emitted by public outdoor light fixtures is wasted, which equals 22 TWh/year of energy wastage. That is equivalent to the following:

★About 3.6 million tons of coal per year.

★ About 12.9 million barrels of oil per year.

Effect on Astronomy:            Astronomers are most affected by luminous pollution. As it makes it harder to view and find extraterrestrial bodies for the astronomers even with the aid of a telescope.

Effect on Humans:                                  Like plants and animals, humans are also regulated by circadian rhythms. The rhythms respond to the light and darkness around any organism, which when altered can result in various health hazards like sleeping disorders, depression, diabetes, cancer, cardiovascular disease, obesity, etc.

How to prevent light pollution?

Given below are some ways to prevent light pollution:-

I) By using warm white lightning as it scatters less.

II) By using shielded outdoor light fixtures.

III) By picking the right exterior light fixtures with the right cutoff angle, which prevents light from escaping above the horizontal plane.

IV) By using motion sensor outdoor fixtures.

V) By using IDA-certified light fixtures. 

Agriculture

When tillage begins, other arts follow. The farmers, therefore, are the founders of human civilization.”

— Daniel Webster

Introduction

It all started thousand of years ago , when the human civilization came into existence . Agriculture was a key to survival . People were farming for there domestic purpose , not for the others .

As the civilization started to grow accustomed of agriculture , they grew food in surplus that enabled people to live in cities. Plants were independently cultivated in at least 11 regions of the world.

The development of agriculture enabled the human population to grow many times larger than could be sustained by hunting and gathering.

It was the beginning of different civilization in different parts of the World. From those civilizations , one of them was our’s The Indus Valley Civilization . Vedic literature provides some of the earliest written record of agriculture in India. Rigveda hymns , describes plowing, fallowing, irrigation, fruit and vegetable cultivation.

Some of the ancient and historical evidence suggests rice and cotton were cultivated in the Indus Valley.

Agriculture : In India and World today .

India ranks second worldwide in farm outputs. As per 2018, agriculture employed Indian work force and contributed 17–18% to country’s GDP.

In 2016, agriculture and allied sectors like animal husbandry, forestry and fisheries accounted for 15.4% of the GDP (gross domestic product) with about 41.49% of the workforce in 2020.India ranks first in the world with highest net cropped area followed by US and China.The total agriculture commodities export was US $ 3.50 billion in March – June 2020.

Agriculture is the primary source of livelihood for about 58% of India’s population. Share of agriculture and allied sectors in gross value added (GVA) of India at current prices stood at 17.8 % in FY20.

During 2019-20 crop year, food grain production reached a record of 296.65 million tonnes. In 2020-21, Government of India is targeting food grain production of 298 million tonnes.

India is among the 15 leading exporters of agricultural products in the world. Agricultural export from India reached US$ 38.54 billion in FY19 and US$ 35.09 billion in FY20.

Agriculture is an important industry in the United States. The agriculture industry, which includes both crops and livestock, is responsible for producing most of the world’s foods and fabrics. Agriculture impacts so many things that it’s hard to imagine a world without this important industry.

Schemes and Initiatives

Due to the high requirement of agriculture . It is important for the government to take initiatives and provide better infrastructure to the farmers. However , the required level of investment for the development of marketing, storage and cold storage infrastructure is estimated to be huge.

The Indian Council of Agricultural Research (ICAR), established in 1905, was responsible for the search leading to the “Indian Green Revolution” of the 1970s. The Union Minister of Agriculture is the president of the ICAR. The Indian Agricultural Statistics Research Institute develops new techniques for the design of agricultural experiments, analyses data in agriculture, and specialises in statistical techniques for animal and plant breeding.

Schemes by government for Indian agriculture :

  • Dairy Entrepreneurship Development Scheme.
  • Rainfed Area Development Programme (RADP)
  • Paramparagat Krishi Vikas Yojana (PKVY)
  • Pradhan Mantri Krishi Sinchai Yojana (PMKSY)
  • National Agriculture Market (e-NAM)
  • Pradhan Mantri Kisan Maandhan yojana.
  • Pradhan Mantri Fasal Bima Yojana (PMFBY)
  • Kisan Credit Card (KCC) scheme.
  • Pashu Kisan Credit Card Scheme.
  • PM-Kisan Scheme.

Conclusion

Agriculture sector is one of the prominent sector in India as well as all over the world . India is becoming self – sufficient in pulses and other crops .

Gone are the days , when India was unable to provide sufficient amount of food to the citizens . Gone are the days , when people used to think agriculture was not as important as other sectors . Gone are the days , when people used to think less of farmers . And gone are the days , when people were less educated about agriculture.

Farming is a profession of hope.

Kaleshwaram project

Hello guys!!

Today I am going to give you guys an insight about a very hot and trending topic “The kaleshwaram project”.

This project is a multi purpose irrigation project on the Godavari river in kaleshwaram in Telangana state.

It’s main purpose is irrigation to crops,supplying power and water. It is constructed to overcome the famine conditions.

From Times of India

In The Kaleshwaram Lift Irrigation System is considered to be one of the world’s largest multi-purpose projects. It is designed to provide water for irrigation and drinking purposes to about 45 lakh acres in 20 of the 31 districts in Telangana, apart from Hyderabad and Secunderabad.

Indian express.com

It’s construction began in 2016 and approximately 1.2 lakh crores were spend in the construction of this Although inaugurated the project is no where near completion.

From The Hans India

This project has at is own fair share of disadvantages too.

This project will displace at least 30,000 people in 19 villages.

It will affect land of about 1 lakh acres (40,015 hectares).

Considering all other costs, this project will be a major burden on the people of the state and farmers for generations to come

From Deccan Chronicle

The result is yet to be known whether the project is a success or not ,but if the result is good then the sacrifices that were done to built the project will not go to waste.

The amount of time, money, and labour spending on this project will never comeback so whether it will live up to the expectation of people or not is the question that is yet to be answered.

Thankyou^^.

Feed them Pawfectly!

What if I offer you crores and crores of money and ask you to stay away from food for days in return? Will you do it? Can you survive without eating? I’m guessing it’s a NO!
Food is one of our necessities. Here ‘our’ not only includes humans but also animals. For animals food (including water) is their only requirement to survive but unfortunately, they don’t even get that.
You’ll have seen dogs, cats, cows, and various other animals come behind us while we walk on the street. They don’t walk behind you to harass you they come to you with hope in their eye. They just need food and a little love rather than getting hit by a stick. Being cruel to them won’t make you superior instead having empathy towards them and treating them like humans will.

Every mother loves to feed their children and would cook many dishes for them but don’t forget those mothers who search for food in a heap of garbage every day just to survive.
Do they deserve this? Of course not!
Nobody deserves this! Then why do they have to do this for their survival?

God has not given them a voice to speak but their eyes are enough to convey their sorrow.
Just feed an animal and see what they do for you in return. Trust me! you’ll be God in their eyes

Things to keep in mind before feeding a stray animal
 • Avoid sweets
Sweets take a lot of time to digest and can result in various health issues in them and can also affect their immunity.

 • Avoid fried and spicy food
Animals might not find fried and spicy food attractive. Avoid feeding them leftovers. Fried and spicy food can lead to many health problems

 • Avoid allergic food
Animals can be allergic to some food items just like humans. Always research before feeding.

 • Do not Overfeed
Every animal has their capacities to eat. Do not force them to eat more, it might make them ill.

 • Avoid plastic bags
Never give them food in plastic bags. They might stick their head inside it and cause breathing problems. Try using plastic bowls.

 • Serve them water
Water is as important as food for them. They can find their water but it’s best to serve them which will make their job much easier.

Wannacry Cyber Attack

What was the cyber attack?

The WannaCry ransomware attack was a worldwide cyber attack in May 2017 by the WannaCry ransomware. It propagated through EternalBlue, an exploit developed by the United States National Security Agency (NSA) for older Windows systems. WannaCry is a ransomware cryptoworm, which targeted computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the Bitcoin cryptocurrency. The worm is also known as WannaCrypt, Wana Decrypt0r 2.0, WanaCrypt0r 2.0, and Wanna Decryptor. It is considered a network worm because it also includes a transport mechanism to automatically spread itself. This transport code scans for vulnerable systems, then uses the EternalBlue exploit to gain access, and the Double Pulsar tool to install and execute a copy of itself. WannaCry versions 0, 1, and 2 were created using Microsoft Visual C++.

When did it happen?

The attack began on Friday, 12 May 2017, with evidence pointing to an initial infection in Asia at 07:44 UTC. Within a day the code was reported to have infected more than 230,000 computers in over 150 countries. Officially the initial outbreak was from 12 May 2017 to 15 May 2017. Organizations that had not installed Microsoft’s security update from April 2017 were affected by the attack.

How did it happen?

The vulnerability WannaCry exploits lies in the Windows implementation of the Server Message Block (SMB) protocol. The SMB protocol helps various nodes on a network communicate, and Microsoft’s implementation could be tricked by specially crafted packets into executing arbitrary code. It is believed that the U.S. National Security Agency discovered this vulnerability and, rather than reporting it to the infosec community, developed code to exploit it, called EternalBlue. This exploit was in turn stolen by a hacking group known as the Shadow Brokers, who released it obfuscated in a seemingly political Medium post on April 8, 2017. Microsoft itself had discovered the vulnerability a month prior and had released a patch, but many systems remained vulnerable, and WannaCry, which used EternalBlue to infect computers, began spreading rapidly on May 12. In the wake of the outbreak, Microsoft slammed the U.S. government for not having shared its knowledge of the vulnerability sooner.

Who did it?

The US and UK governments have said North Korea was responsible for the WannaCry malware attack affecting hospitals, businesses and banks across the world in May 2017. Ironically, it was allegedly developed as a cyber-attack exploit by the US National Security Agency. Although they were reported to have known of the tool’s vulnerabilities, the NSA didn’t bring it to Microsoft’s attention until the hacker group called Shadow Brokers leaked EternalBlue to an obscure website. Further analysis of the attack by companies such as Symantec revealed links to the Lazarus group who in turn have been linked to North Korea although the attack does not bear the hallmarks of a nation-state campaign.

Which security services were violated?

WannaCry spread using an exploit called EternalBlue, created by—and subsequently stolen from—the U.S. National Security Agency (NSA). EternalBlue enabled attackers to discover vulnerable computers on the target network. WannaCry also leveraged an NSA backdoor called DoublePulsar to install WannaCry on the networkThe WannaCry ransomware attack hit around 230,000 computers globally .A third of NHS hospital trusts were affected by the attack. Terrifyingly ambulances were reportedly rerouted, leaving people in need of urgent care in need. It was estimated to cost the NHS a whopping £92 million after 19,000 appointments were canceled as a result of the attack. As the ransomware spread beyond Europe, computer systems in 150 countries were crippled. The WannaCry ransomware attack had a substantial financial impact worldwide. It is estimated this cybercrime caused $4 billion in losses across the globe.

Bose-EinsteinCondensate The 5th Matter

QuantumPhaseTransition.svg

In condensed matter physics, a Bose–Einstein condensate (BEC) is a state of matter (also called the fifth state of matter) which is typically formed when a gas of bosons at low densities is cooled to temperatures very close to absolute zero (−273.15 °C or −459.67 °F). Under such conditions, a large fraction of bosons occupy the lowest quantum state, at which point microscopic quantum mechanical phenomena, particularly wavefunction interference, become apparent macroscopically. A BEC is formed by cooling a gas of extremely low density (about one-hundred-thousandth (1/100,000) the density of normal air) to ultra-low temperatures.

This state was first predicted, generally, in 1924–1925 by Albert Einstein following and crediting a pioneering paper by Satyendra Nath Bose on the new field now known as quantum statistics.

This transition to BEC occurs below a critical temperature, which for a uniform three-dimensional gas consisting of non-interacting particles with no apparent internal degrees of freedom is given by:{\displaystyle T_{\rm {c}}=\left({\frac {n}{\zeta (3/2)}}\right)^{2/3}{\frac {2\pi \hbar ^{2}}{mk_{\rm {B}}}}\approx 3.3125\ {\frac {\hbar ^{2}n^{2/3}}{mk_{\rm {B}}}}}{\displaystyle T_{\rm {c}}=\left({\frac {n}{\zeta (3/2)}}\right)^{2/3}{\frac {2\pi \hbar ^{2}}{mk_{\rm {B}}}}\approx 3.3125\ {\frac {\hbar ^{2}n^{2/3}}{mk_{\rm {B}}}}}

where:

{\displaystyle \,T_{\rm {c}}}is the critical temperature,
\,nthe particle density,
\,mthe mass per boson,
\hbar the reduced Planck constant,
{\displaystyle \,k_{\rm {B}}}the Boltzmann constant and
\,\zeta the Riemann zeta function; {\displaystyle \,\zeta (3/2)\approx 2.6124.}\,\zeta(3/2)\approx 2.6124. 

Interactions shift the value and the corrections can be calculated by mean-field theory. This formula is derived from finding the gas degeneracy in the Bose gas using Bose–Einstein statistics.

Superfluidity of BEC and Landau criterion

The phenomena of superfluidity of a Bose gas and superconductivity of a strongly-correlated Fermi gas (a gas of Cooper pairs) are tightly connected to Bose–Einstein condensation. Under corresponding conditions, below the temperature of phase transition, these phenomena were observed in helium-4 and different classes of superconductors. In this sense, the superconductivity is often called the superfluidity of Fermi gas. In the simplest form, the origin of superfluidity can be seen from the weakly interacting bosons model.

TACHYON A PARTICLE THAT HELPS US TO TIME TRAVEL…

Tachyon, hypothetical subatomic particle whose velocity always exceeds that of light. The existence of the tachyon, though not experimentally established, appears consistent with the theory of relativity, which was originally thought to apply only to particles traveling at or less than the speed of light. Just as an ordinary particle such as an electron can exist only at speeds less than that of light, so a tachyon could exist only at speeds above that of light, at which point its mass would be real and positive. Upon losing energy, a tachyon would accelerate; the faster it traveled, the less energy it would have.

The name ‘tachyon’ (from the Greek ‘tachys,’ meaning swift) was coined by the late Gerald Feinberg of Columbia University. Tachyons have never been found in experiments as real particles traveling through the vacuum, but we predict theoretically that tachyon-like objects exist as faster-than-light ‘quasiparticles’ moving through laser-like media. (That is, they exist as particle-like excitations, similar to other quasiparticles called phonons and polaritons that are found in solids. ‘Laser-like media’ is a technical term referring to those media that have inverted atomic populations, the conditions prevailing inside a laser.)

an experiment at Berkeley to detect tachyon-like quasiparticles. There are strong scientific reasons to believe that such quasiparticles really exist, because Maxwell’s equations, when coupled to inverted atomic media, lead inexorably to tachyon-like solutions.

“Quantum optical effects can produce a different kind of ‘faster than light’ effect (see “Faster than light?” by R. Y. Chiao, P. G. Kwiat, and A. M. Steinberg in Scientific American, August 1993). There are actually two different kinds of ‘faster-than-light’ effects that we have found in quantum optics experiments. (The tachyon-like quasiparticle in inverted media described above is yet a third kind of faster-than-light effect.)

“First, we have discovered that photons which tunnel through a quantum barrier can apparently travel faster than light (see “Measurement of the Single-Photon Tunneling Time” by A. M. Steinberg, P. G. Kwiat, and R. Y. Chiao, Physical Review Letters, Vol. 71, page 708; 1993). Because of the uncertainty principle, the photon has a small but very real chance of appearing suddenly on the far side of the barrier, through a quantum effect (the ‘tunnel effect’) which would seem impossible according to classical physics. The tunnel effect is so fast that it seems to occur faster than light.

“Second, we have found an effect related to the famous Einstein-Podolsky-Rosen phenomenon, in which two distantly separated photons can apparently influence one anothers’ behaviors at two distantly separated detectors (see “High-Visibility Interference in a Bell-Inequality Experiment for Energy and Time,” by P. G. Kwiat, A. M. Steinberg, and R. Y. Chiao, Physical Review A, Vol. 47, page R2472; 1993). This effect was first predicted theoretically by Prof. J. D. Franson of Johns Hopkins University. We have found experimentally that twin photons emitted from a common source (a down-conversion crystal) behave in a correlated fashion when they arrive at two distant interferometers. This phenomenon can be described as a ‘faster-than-light influence’ of one photon upon its twin. Because of the intrinsic randomness of quantum phenomena, however, one cannot control whether a given photon tunnels or not, nor can one control whether a given photon is transmitted or not at the final beam splitter. Hence it is impossible to send true signals in faster-than-light communications.

JOURNEY TO SANITY – DOUBLE STANDARDS

EMOTIONS ARE GENDER NEUTRAL

We have been conditioned in such a way that it is believed, that women are supposed to be fragile and sensitive in nature where as men are supposed to be thick-skinned and emotionally numb. However, in reality emotions are gender neutral. It’s not manly to be strong and harsh. And similarly, it’s not feminine to be weak and to cry. The experiences faced by men or women might be different but since they are both humans and have emotions, it is not wrong to express it.
(So, the next time someone tells you to man up and stop crying, you know what to say)

SHARING RESPONSIBILITIES AND RESPECTING THE OPINIONS OF YOUR PARTNER DOES NOT MAKE YOU A ‘JORU KA GULAM‘

Understanding, Compassion and Mutual – Respect should be the basis for any healthy relationship. It is the basic need of a human to be heard and acknowledged. Hence, it doesn’t make a man a ‘Joru Ka Gulam’ if he is respectful to the opinions of his partner and understands him/her. Society in general tends to question and mock those changes that question their years of belief. In order to avoid their inner-conflict, they discourage the progressive mass so that they don’t have to change and no one can question them. (Yes, kind of like a defence mechanism – Pointing fingers at the other person before they point at you).

FAMILY RESPONSIBILITY SHOULD NOT BE THE SOLE RESPONSIBILITY OF A MAN OR A WOMEN.

Two people form a relationship and they are called partners for a reason. They are part responsible for every aspect of a household. So why should the burden of the entire family fall on the shoulders of a single person. It is normal for a woman to have a successful career and to support a family financially. (No, it doesn’t make him less manly by earning less or letting his wife handle finances). Similarly, household chores should not be the sole responsibility of a women. It doesn’t make a man submissive if he cooks for his partner or does basic household chores. Rather, such relationships are built on mutual respect and compassion which tend to last longer.

STRONG, BRAVE AND INDEPENDENT ARE NOT TERMS SYNONYMOUS WITH MEN.

It is acceptable for a women to be strong yet sensitive, to be scared yet courageous enough to face it. Adjectives like strong, brave are often used for men, whereas it’s completely normal for a women to have each of those qualities. We have women officers who are equally as brave as the men. There are men who prefer household work over finances and it doesn’t make them dependant on their partners or submissive in any way.

Pet.

A pet, or companion animal, is an animal kept primarily for a person’s company or entertainment rather than as a working animal, livestock or a laboratory animal. Popular pets are often considered to have attractive appearances, intelligence and relatable personalities, but some pets may be taken in on an altruistic basis (such as a stray animal) and accepted by the owner regardless of these characteristics.

Two of the most popular pets are dogs and cats; the technical term for a cat lover is an ailurophile and a dog lover a cynophile. Other animals commonly kept include: rabbits; ferrets; pigs; rodents, such as gerbils, hamsters, chinchillas, rats, mice, and guinea pigs; avian pets, such as parrots, passerines and fowls; reptile pets, such as turtles, alligators, crocodiles, lizards, and snakes; aquatic pets, such as fish, freshwater and saltwater snails, amphibians like frogs and salamanders; and arthropod pets, such as tarantulas and hermit crabs. Small pets may be grouped together as pocket pets, while the equine and bovine group include the largest companion animals.

Pets provide their owners (or “guardians”) both physical and emotional benefits. Walking a dog can provide both the human and the dog with exercise, fresh air and social interaction. Pets can give companionship to people who are living alone or elderly adults who do not have adequate social interaction with other people. There is a medically approved class of therapy animals, mostly dogs or cats, that are brought to visit confined humans, such as children in hospitals or elders in nursing homes. Pet therapy utilizes trained animals and handlers to achieve specific physical, social, cognitive or emotional goals with patients.

People most commonly get pets for companionship, to protect a home or property or because of the perceived beauty or attractiveness of the animals. A 1994 Canadian study found that the most common reasons for not owning a pet were lack of ability to care for the pet when traveling (34.6%), lack of time (28.6%) and lack of suitable housing (28.3%), with dislike of pets being less common (19.6%). Some scholars, ethicists and animal rights organizations have raised concerns over keeping pets because of the lack of autonomy and the objectification of non-human animals.

Inventory control and valuation

With the advancements and introduction of new and efficient techniques of inventory control and valuation, it is essential for every business to keep up and adopt these methods to improve their profitability and efficiency.

What is Inventory control and valuation?

Inventory control is the process of maintaining sufficient stock of raw material and ensuring the continuous process for uninterrupted production schedule. The main objective is to avoid overstocking or understocking. It is essential to do so because:

  1. Overstocking leads to higher costs of holding the inventory
  2. Understocking acts as a hindrance to the production process and interrupts the flow

It reduces wastage and cost by allowing the enterprise to purchase raw material economically by purchasing the exact number of units needed for production at the time.

There are two commonly used inventory control techniques- Just in time Approach (JIT) and Economic order quantity (EOQ).

  • Just In Time (JIT) Approach: This approach focuses on increasing efficiency and minimizing inventory. This is done by aligning the raw material orders directly with the production schedules on an as-needed basis. It ensures minimal wastage of material and reduces storage cost as well. However, it relies on steady production, high-quality workmanship and most importantly, reliable suppliers. It can be used for items that are not essential for daily production and are not needed in huge quantities. For example, machine spare parts.
  • Economic Order Quantity: This method focuses on determining the number of units to be purchased at one time which ultimately reduces the ordering and carrying cost of the company. Ideally, it is used when demand for a particular input is constant throughout the year. This method is ideal for placing orders for raw material that is needed in huge quantities and is a common ingredient or material required in the production of various goods.

Inventory Valuation is the process of determining the monetary value of the inventory with the company. The value is ascertained on the basis of the cost incurred to acquire to inventory and get it ready for sale.

It is essential that the value of the inventory is accurate as it-

  • is used to determine Cost of Goods Sold (COGS) and Gross Profit for the year.
  • helps in ascertaining the financial position of the company
  • allows companies to maintain accurate records and gives a realistic picture

There are several methods of Inventory Valuation-

  • First In First Out
  • Last In Last Out
  • Weighted Average Method
  • First In First Out: This method is based on the premise that the first inventory purchased is the first to be sold. It is one of the most common methods of inventory valuation used by businesses as it is simple and easy to understand. Unfortunately, the FIFO model fails to present an accurate depiction of the costs when there is a rapid hike in prices.
  • Last in First Out: Under this inventory valuation method, the assumption is that the newer inventory is sold first while the older inventory remains in stock. This method is hardly used by businesses since the older inventories are rarely sold and gradually lose their value. This results in significant loss to the business.
  • Weighted Average Method: Under the weighted average cost method, the weighted average is used to determine the amount that goes into the cost of goods sold and inventory. It is the most efficient method and gives a realistic picture of the inventory value.

It is essential to weigh the pros and cons of the inventory valuation and control methods mentioned above and choose the ones that would give the most realistic and accurate picture of the company’s inventory according to the nature of the business operations.

DIGNITY OF LABOUR

“No work is insignificant. All labor that uplifts humanity has dignity.” Martin Luther King, Jr.

EVERY WORK MUST BE GIVEN HONOUR

The word ‘dignity’ means the ‘quality of being worthy of honour or respect So the expression ‘dignity of labour’ means honour or respect’ received through or for hard work. That is why it is said that ‘work is worship’. Every type of work need labour, physical or intellectual. But the word labour’ is generally used in the sense of physical labour which is as important as intellectual labour. The production of cereals, construction of buildings and the other constructive work require physical labour. Man cannot do without hard labour. So, he should do all types of work.

WRONG NOTION ABOUT MANUAL LABOUR

But the attitude of the educated and the gentlemen towards manual labour is wrong. They are of the opinion that manual work is fit for the illiterate men only. But they are mistaken. All intellectual work involves some sort of physical labour. Even a student has to labour hard to pass the examination. All artists, scientists and writers whose work is intellectual have to spend hours with patience. The manual work too needs the exercise of intellect. A carpenter, an ironsmith, a goldsmith, a barber, etc. whose work is physical have to exercise intellect to improve the quality of their work.

MANUAL LABOUR: THE ROOT OF ALL PROGRESS

And it is the manual labour which is at the root of all progress. It is rightly said that true labour never goes in vain. Labour has its own importance. Nothing can be achieved in the world without labour. The prosperity of a country depends on its agricultural products. So, there is no humiliation in the cultivation of land. The people of the West do their work themselves. They look upon labour as something honourable and sacred. Such is the importance of labour that its dignity is recognised by all. It is the source of health and happiness.
