Science Experiments

By: Aamarpali Puri

Experiment .1: Which grape is heavier?

(Cohesion and adhesion)

Material required: Fresh grapes, 7-Up Soda, Clear drinking glass

Method: Pour and fill a glass with 7-Up Soda. Peel one grape and take an unpeeled grape. The two grapes are dropped at the same time in glass. The unpeeled grape rises to the top of the cup while the peeled grape remains at the bottom.

Questions:

  1. Why does the peeled grape sink to the bottom?
  2. Which of the two grapes is lighter in weight?
  3. What makes the unpeeled grape float?
  4. Would an unpeeled grape also float in water?

Explanation: This activity relates adhesive and cohesive forces (CO2 bubbles adhering to the grape skin) and the effects of hydrophobic and hydrophilic properties. This demonstration is suitable for studying bonding interactions, i.e. hydrogen bonds. The unpeeled grape has water-repelling–hydrophobic–properties and thus the CO2 bubbles from the 7-Up can adhere to this surface. The peeled grape does not have hydrophobic skin, thus it is hydrophilic–water-attracting. The bubbles of the 7-Up have no way of adhering to the grape. This causes the grape to stay at the bottom of the glass. The unpeeled grape becomes lighter in weight, because of the adhering bubbles, and rises to the surface of the liquid. There it loses some of the bubbles to become heavier again. It may sink for a while, picking up more bubbles, to bob up to the surface again.

Precautions: The soda used should be non flat.

 

Experiment .2: Stem end blackening in potato.

(Redox reaction)

Material Required: Potato, water, burner, baking soda, tartar, pH paper

Method: A potato is cooked in boiling water for 40 minutes. After being removed from the water and allowed to cool, the end of the potato that has been connected to the plant will produce a dark gray color. This is called “Stem-end Blackening” region.

Questions:

Why a particular portion of potatoes shows change in colour after boiling.

What is the effect of pH of water on stem end blackening?

Explanation: The reason for this color change is that iron ions in the potato are experiencing a “redox” reaction. During cooking ferric (Fe+3) ions are formed from ferrous (Fe+2) ions by the gaining of electrons from phenolic substances in the region where darkening has occurred.

Precautions:

The water in which we are boiling potatoes should be checked for pH because this “Stem-end Blackening” is pH sensitive. Neutral and basic cooking solutions produce a greater amount of blackening effect, and acidic water causes little to no color change.

Note: Baking soda will be used as a sweetening agent to make the basic cooking solutions, and cream of tartar will serve in making the acid solution. Universal indicator paper will be used to check that each solution is in the specified pH range.

 

Experiment .3 Negative inflation

Material Required: Baloon, Plastic bottle, hot water, cold water

Method: Fill a plastic (PET) bottle with hot water (NOT boiling water) and fill a bowl with cold water. Let them sit for one minute, then empty the bottle quickly. Stretch a balloon over the open end of the bottle and push the bottle down into the cold water. The balloon is pulled in and get inflated inside the bottle.

Common Questions

Question 1. : Why it happens that when you squeeze egg completely surrounding it with your hand it doesn’t break but it breaks if you are wearing ring?

Answer 1. Eggs are surprisingly strong and will stand up to forces applied evenly to them. They don’t stand up so well to uneven forces, which is why they crack easily on the side of a bowl or break when they hit the ground. Hold an egg, completely surrounding it with your hand. Squeeze it, making sure that the pressure is even all around. You should be able to squeeze it very hard without breaking it (do this over a sink or bowl just in case). The egg may break if it is already slightly cracked, or if you are wearing a ring.

Questions 2. : Why does the balloon inflate into the bottle?

Answer 2. The warm water heats the bottle which, in turn, heats the air inside the bottle after the water is poured out. When the bottle is placed in the cold water, the air inside cools and contracts, causing outside air to be drawn in, pulling the balloon in and inflating it inside the bottle.

Symmetry

By Aamarpali Puri

Symmetry means agreement in proportion/ agreement in dimensions when a certain portion of an object looks exactly like another portion of the same object. Symmetry is exhibited everywhere i.e crystal cubes, designing, in plants, structure of flowers, water droplets and even in music. It leads to pleasing proportions, regularity, harmonious arrangements.

In chemistry systematic discussion of symmetry is termed Group Theory. Molecules are classified according to their symmetry. The collection of symmetry elements present in a molecule forms a “group”, typically called a point group. A point group has all the symmetry elements (points, lines, and planes) which intersect at a single point.

Symmetry helps us in determination of structure of molecules and understanding their Stereochemistry. Symmetry helps in Analysis of Molecular Vibrations, finding out the Chirality and polarity of a molecule.

To understand the symmetry of various elements it is necessary to know the geometry of various molecules. This can be obtained by Valence Shell Electron Pair Repulsion (VSEPR) theory, which helps in prediction of the shapes of molecules and bond angles of these molecules. Various shapes of molecules are Linear (Carbon dioxide), Bent (Water), Planar (Boron Trifluoride), Pyramidal (Nitrogen Trifluoride), Square Planar (Xenon Tetrafluoride), Tetrahedral (Carbon Tetrachloride), Pentagonal (not known to exist) and Octahedral (Sulphur hexafluoride) etc.

Symmetrical molecules have Symmetry elements (imaginary geometrical entities) such as points, lines and planes. Some geometric operations are reflection, rotation or inversion, when performed on molecules gives rise to indistinguishable configuration of same molecule. So molecules can have configurations which are alike in all respects except chemical nature. Linear elements have an infinite number of planes of symmetry. If in a molecule x, y, z coordinates are changed to –x, -y, -z and if after that too molecule presents an indistinguishable configuration then origin is called Centre of Symmetry. If an imaginary line is drawn from an atom to the centre of the molecule and extended on the other side by the same distance and meets a similar atom, the molecule is said to have centre of symmetry. Example: a cube. All linear molecules when rotated through any angle with respect to the bond axis, present an indistinguishable configuration possess an Axis of Symmetry. Example HCl

Radial symmetry is rotational symmetry around fixed point (Centre of Symmetry) Radial symmetry can be termed as cyclic or dihedral symmetry. The notation for Cyclic Symmetries is Cn. Example: Star fish, Hibiscus flower.

Strip Pattern Symmetry can be classified into following patterns Translational symmetry, Horizontal mirror symmetry, vertical mirror symmetry, Rotational Symmetry, Glide Reflection Symmetry. Example: Snakes.

Bilateral symmetry is symmetry across a line of reflection. Two halves are mirror images of each other exhibits Bilaterally Symmetrical.

Some Beautiful examples of symmetry in nature are: Honey Comb, Sunflower, Peacock, Spider Webs and Pine Cones etc.

Silicon Valley Syndrome/ Sitting Syndrome

By: Rajesh Konnur

The postural trainer, Lumo Back’s research findings examined the physical and mental health symptoms that arise spending way too much time sitting in front of a computer screen thereby giving rise to Silicon Valley Syndrome. The results show that 60% of participants reported that they have experienced adverse health effects as a result of technology.

“I have technology as much as anyone – I am a tech company founder, after all”, CEO Monisha Perkash said to Venture Beat. “While our computers and devices can help us feel more productive, this study shows that more people are using technology in ways that will devolve our bodies than those that are using it in a healthy manner. This abuse of technology could very well set up for a series of health pandemics in the not so far –off future”. Perkash said that Lumo Back’s goal is to use technology in a way that helps, rather than destroys, our body.

 Eye strain is the most common ailment, followed by back pain, neck pain, headaches, wrist pain, carpel tunnel disorders and insomnia.

Women are more likely than men to be affected and are more likely to try and resolve their symptoms by taking a pill.

Young Americans are three times likely as older Americans to cut back on their use of gadgets when they start getting those aches and pains. In contrast, older Americans were twice as likely to take prescription medications to alleviate their symptoms.

The most common measures to combat SVS are posture correction, stretching, medication, taking breaks, exercise and consultation.

Back pain is widespread and pervasive problem. About 80% of Americans experience significant back pain sometime in their lives and that pain cost more than 50 billion USD per year. It is a leading cause of missed work days, disability claims, visits to the doctor, outnumbered only by the common cold.

Lumo Back found that the average American spends more than three – quarters of their work day sitting.

We sit, we slouch, we type, we strain our eyes and necks and while we may be writing prolific (& eloquent, I might add) articles, building powerful software, coordinating marketing campaigns, chatting on facebook; responding to email & generally living life in the always on internet era, we are also hurting our bodies.

Human beings were not meant to sit all day long, & the average computer worker could easily spend 48,360 hours sitting at work over a 30 year career.

Lumo Back describes sitting as “the new smoking”. People who spend the most time sitting increase their risk or diabetes, cardiovascular events and death.

Plant Tissue culture- simplified

By: Krishnakumar, V.G

Introduction

This article is meant for familiarizing tissue culture to common man and hence, complicated terms and terminologies are least used. Technology is also elaborated to simplicity so that a layman can have an understanding of this developing technology.

Tissue culture is the synonym for scientific asexual regeneration of living organisms as far as modern agriculturists and the whole world of biologists. Technically, tissue culture is a form of vegetative propagation. It is the science of artificial replication of a living plant or animal from a single cell or group of cells- tissue. Tissue culture is also known as micro propagation.

Indian epics have very well exposed to this science in the very past. Agasthyamuni, the founder of Sidhavydya (a branch of Ayurveda) was born in a pot. When Varuna Maharshi saw Urvashi and Rambha, the resultant semen was collected in pot. Biologically, Agasthyamuni was thus haploid! (half of the chromosome numbers in cell nucleus. Normal living being developed through sexual regeneration- union of sperm and ovum which are haploid- is diploid. Human sperm and ovum have 23 chromosomes and a human being’s cell will have 46 chromosomes)

There is energy in every living cell which has of certain life. Before the expiry of the lifespan of the cell, if it is stimulated it can reproduce the next generation having original characteristics of the donor organism. Unlike animal cells which can reproduce that particular cells (a cell of skin can produce only skin tissue, a liver cell can produce only liver tissue) when stimulated, plant cells have a phenomenon, totipotency (the ability of a single cell to divide and produce all of the differentiated cells in an organism- Wikipedia)

In our garden, we used to regenerate flowering plants like rose, etc. using the branch cuttings and planting in filled-in pots. Within few days, new plant establishes. Likewise, if we plant a live branch of a mango tree and dip the cut end in rooting hormone and plant, another mango sapling, exactly having the qualities of the mother tree, will start establishing. The tissues of cut end of the plant stem are stimulated by the hormone to produce roots and thus whole plant system is generated.

Process of plant tissue culture.

Father of plant tissue culture is Mr. Gottlieb Haberlandt, the German scientist of Academy of Science. It was in 1902 on his experiments on the culture of single cell the first true cultures were obtained by Gautheret from cambial tissue of great maple tree.

Tissue culture process is having two stages, viz., in vitro process (inside lab) and ex vitro (in natural condition) process

In vitro process

Cell from any part of a plant can be developed to a full-fledged plant. This can be done in a highly suitable environment. The process is given below:

The growing part of the ideal mother plant is cut (explants), cleaned and sterilized to free from all impurities, pathogens and microbes under various sterilizing process. This part is cut to smaller parts and then kept in growth media borne vessel. Growth media is the compound of various minerals, salts vitamins and plant hormones prepared in a highly protected hygienic environment. This vessel is kept for a fixed period in the growth room which is having a maximum of 25oC and minimum 18oC and 12 hours lighting. During this process, the cells undergo uncontrolled and undefined division (exactly similar to cancer growth) and result in callus formation. This callus is later multiplied under sterile atmosphere. Normally, shoot development is done initially and later when there is sufficient quantity of cultures are ready, rooting initiation is done. After establishing roots, the culture plants are transferred to further process under Ex Vitro process, i.e, outside the laboratory.  The laboratory manager can decide the development of shoots or roots in culture as it is done by adding the concerned hormone in the culture media.

Ex vitro process

The cultures received from the laboratory are washed off the media and then split. The split culture plants are separated and planted in wet cocopeat-filled portrays (similar to the egg-packing case) and kept in poly houses which has high humidity and temperature range of 26-30o C in daytime and 25-28o C in night time and humidity of 80%. During these conditions, the real root formation and normal function of plant develops. After 2 weeks, these plants are taken out, and dead ones are removed. The survived plants are then transferred to fresh protrays filled with wet cocopeat and regular watering is done. After 90 days of such poly house life, the plants are transferred to shade net house, where the plants will get in touch with real soil in nursery bed and finally to poly bags or root trainers for sales.

The need for tissue culture

As already stated, tissue culture is a sort of photocopying! We can produce the exact offspring’s of a plant as much as we require from a small portion of that plant. When there is a heavy demand for a particular plant and seed availability would be inadequate, tissue culture is the answer. When there was gregarious flowering of bamboos in Northeast India and regeneration was in docks, Government of India resorted to tissue culture of bamboos to meet the need of planting materials by setting up a Tissue Culture Laboratory for bamboo propagation in Nagaon Paper Mill, Jagi Road, Assam, under Government of India owned Hindustan Paper Corporation. This tissue culture lab facility can produce one billion plantlets of various bamboo species annually.

In India, banana is widely produced under tissue culture method and thus profit making.

Tissue culture can ensure plant purity. The costs are high in in vitro stage, where costly organic chemicals are used and high cost for lab establishments are also to be met with. Skilled technicians are required for this delicate work. Hygiene is of high priority to establish success in tissue culture. Uncontrolled contamination in culture at any stage can result in heavy loss.

Tissue culture facility can be developed for just 1000 plants to even billions of plants per month. It can be established in a building having an area of 800 square feet! Government of India is providing financial and technical support to new entrepreneurs. Details can be available in the websites of department of biotechnology or national horticulture mission.

 Conclusion

Tissue culture is the most updating field of technology and success lies with the customization of technology for the requirement of plants and its demand. In our country, this technology can transform the agriculture scenario by increased output, by incorporating the genetic engineering methods. As every biotechnology ventures are having high risk for want of adequate technology and technicians, less entrants are in the field. Tissue culture should be introduced as a subject in the Vocational Higher Secondary syllabus to prepare technicians in the field.

Gambling is risking money on a chance outcome

By: Prapanna Lahiri

Professor Thomas Clark of the University of Nevada, Las Vegas, in his book ‘The Dictionary of Gambling and Gaming (Clark 1987, 88)’ defined Gambling as “of or pertaining to risking of money or something of value on the outcome of a chance event such as card or dice game.” According to Clark the activity of gambling essentially has three elements – consideration, chance and reward,

1) Consideration is the money staked which represents something of value,

2) Chance is a randomly occurring risk that may or may not be calculated,

3) Reward is something of value that may be in excess of the value of the consideration.

One is said to be indulging in Gambling when the person takes part in a game during which money or something of monetary value is staked in order to win money or a prize dependent on certain odds which literally means chances of something happening. So the key words here are Odds (chances or likelihood of an event), Risk and Reward. The outcome of the game is down to a chance; so as a consequence of gambling one might leave with less money than one started off with, and sometimes with nothing at all. The likelihood of a given event’s occurrence is mathematically termed probability. In simple terms probability is worked out by dividing the number of specific outcomes with the number of possible outcomes. It is expressed as a number between 1 and 0. An event with probability 1 means the event is certain. The probability of a flipped coin landing either on ‘heads’ or ‘tails’ is 1 since there is no third outcome possible. But the probability of a coin toss landing on ‘heads’ is 1 in 2 since the chance of landing on ‘tails’ is equally likely. Again while rolling a dice the odds of the number six to come up which is a specific outcome against six possible outcomes that are the dice landing on one, two, three, four, five or six. The probability here is 1 in 6. Unless one can foresee the future certainly, the outcome of a rolled dice or flipped coin remains unknown and unpredictable, so we can say that the outcome is random. Randomness means that each possible outcome has the same chance or probability of happening. In gambling despite what a player might think it is not possible to work out or control an outcome which is down to a chance and randomness. So, anyone who tries to control this often ends up risking a lot of money.

In every game of betting or gambling, the “odds” or chance of a person winning a bet always works against that person. The people offering the bet like the casino, bookmaker, slot machine owner etc. always hold the “edge” in so far as the game or the machine is so designed that it always works in their favour to ensure they will in all cases be left with surplus money.

Some common types of gambling where money is risked to win prizes based on chance are:

  • Lottery tickets: Money is raised by selling numbered tickets and prizes are given from the money so raised to the holders of numbers drawn at random.
  • Raffle tickets: Numbered tickets are sold with each number standing a chance of winning a prize earmarked for that number. Copies of these numbers are drawn from a container to give away the prize attached to a number.
  • Bingo: A game of chance (sometimes called Housie outside America) wherein numbers are drawn at random and players match these numbers printed on 5×5 cards. The first person who achieves a specified pattern on the card from the drawn numbers shouts out the word “Bingo!” and wins a pre-announced prize after the claims are crosschecked.
  • Card games: Gambling games that are played with cards like Rummy, Baccarat, Poker, Black jack etc.
  • Casinos: Casino is a public place, sometimes, attached to hotels where a variety of games like Slot machines, blackjack, roulette, baccarat etc. can be played. Prizes based on chance outcomes are offered.
  • Betting on sporting events: An amount is staked on predicting the outcome of a sports event.

Chemistry Misconceptions

By :  Aamarpali Puri

In Chemistry, there are often many ideas that are frequently misinterpreted. Sometimes because of students coping with making sense of abstract concepts. Since science is constantly changing to adapt to new discoveries and methods, some misconceptions may be due to old ideas or legends. Following is meant to generate an awareness of some of the misconceptions found in Class IX Chemistry, particularly that of the atomic and molecular models.

Misconception

“Proper” concept (to date, of course!)
Atoms
Atoms can be seen with a microscope. Atoms cannot be seen with a microscope. The extent of an atom’s small size is often not well understood. For example, there are about one million atoms across the width of human hair, but many students guess a number in the hundreds or thousands.
Atoms are alive (because they move)

Atoms vibrate because they all possess some thermal energy. They do not possess the characteristics of living things (i.e. needing energy to survive, producing wastes, reproduction, adaptability, etc.). The nuclei of cells and atoms are not synonymous.

Atoms are like cells with a membrane and nucleus
Atoms can reproduce after the nuclei divide
Atoms have electrons circling them like planets around a star

Electrons do not follow a simple circular pattern around the nucleus.

An electron shell is like an eggshell or clamshell, thin and hard Shells are not physical shells like eggshells. They are not thin or hard. They are regions around the nucleus where electrons can be found.
The electron shell is there to protect the nucleus, like an eggshell and a yolk
The electron cloud is like a rain cloud, with electrons suspended in it like droplets of water.

The cloud contains the electrons but is made of something else

Electrons are not suspended motionless in the “electron cloud”. Instead, they are constantly moving throughout the “cloud”, which is not made of any other kind of matter.
The electron shell is a matrix of some kind of stuff with electrons embedded in it
Atoms “own” their electrons There are not different kinds of electrons for different atoms. Atoms do not “possess” their specific electrons. Electrons are the same and can be transferred from one atom to another.
Molecules
Molecules are basic, simple, indivisible entities Molecules are made of smaller entities (atoms) which reorganized into different molecules. Therefore molecules are divisible.
Molecules of solids are hard, molecules of gases are soft

Molecule shape, size and mass do not change between solid and gas phases. Just because the phase as a whole appears different, e.g. often the gas is less visible than when in the solid form, doesn’t mean that the molecules themselves have changed, only the forces between them. Changes of state are physical changes.

Molecules of solids are biggest, molecules of gases are smallest
Molecules of solids are cubes, molecules of gases are round
Vapour molecules weigh less than solid molecules (e.g. water vapour vs. ice)
Molecules expand when heated Molecules themselves do not expand. The substance heated may appear to expand because heat causes molecules to move faster (and further apart).
Chemical Bonds
Molecules are glued together Forces of attraction hold molecules together, not glue.
Bonds store energy,

Breaking chemical bonds releases energy,

Bond making requires energy

Not all bonds release energy when broken or require energy to form. Exothermic reactions can form new molecules in which the products possess less energy than the reactants; hence, release energy when the bonds form and require energy to be broken.
Ionic pairs, such as Na+ and Cl, are molecules Ions are not considered molecules, which contain covalent bonds. A better word to use for ionic pairs in ionic compounds may be formula unit.
The chemical bond is a physical thing made of matter Chemical bonds are not made of a separate form of matter, but the electrons that are shared and forces of attraction.
Chemical Bonds –Ionic
Ionic compounds form neutral molecules, such as Na+Cl molecules, in water In water, ionic compounds dissociate into their ions, which are not neutral molecules because they possess a charge and the solution can act as an electrolyte.
Bonds within “ionic molecules” are stronger than inter-molecular forces Ionic compounds are not composed of “molecules”, but of ions which are attracted to one another. For example, an Na+ ion that is surrounded by Cl ions is attracted to all of the Cl ions, even though they are not all considered part of the “formula unit”. It is these bonds that are broken when the ionic compound is dissolved in water, resulting in Na+ and Cl ions.
Na+Cl bonds are not broken in dissolving; only inter-molecular bonds are broken
Chemical Bonds –Covalent
Electrons know which atom they came from There are not different kinds of electrons for different atoms. Atoms do not “possess” their specific electrons. Electrons are the same and can be transferred from one atom to another.
Atoms know who owes them an electron
Electron pairs are equally shared in all covalent bonds Electrons pairs are not shared equally in all covalent bonds. In some, one atom attracts the electron pair more than the other atom (i.e. a difference in electronegativity), and causes the electron pair to be closer to it than to the other atom.
The strengths of covalent bonds and intermolecular forces are similar The strength of a covalent bond, an intramolecular force (within the molecule, i.e. between atoms), is much greater than that of intermolecular forces (between molecules). Hence, molecules can be pulled apart more easily than breaking apart the molecules themselves.
Chemical Reactions
Freezing and boiling are examples of chemical reactions Freezing and boiling are examples of changes of state, which are physical reactions, not chemical. Other changes of state include melting, condensation, and sublimation. One characteristic that changes of state do share with chemical changes: energy is either added or removed from the system, unlike other physical changes.
Physical changes are reversible while chemical changes are not A very common misconception. Chemical changes are also reversible. Consider equilibrium reactions in which forward and backward reactions are both occurring at the same time, as well as Le Chatalier’s Principle. Some physical changes are also hard to reverse, for example, crushing a rock.
The original substance vanishes “completely and forever” in a chemical reaction The original substance can be produced if the reaction can be reversed under the necessary conditions.
Mass is conserved, but not the number or species of atoms Atoms are not created or destroyed in standard chemical reactions. Therefore, the number and species of atoms do not change, and hence mass is also conserved.
Reactions that proceed more rapidly also proceed further (more completely.) This shows a discrepancy between the concepts of speed and completeness. A reaction can reach equilibrium before it has been “completed”, regardless of how fast the reaction proceeds.
Chemical reactions will continue until all the reactants are exhausted Reactions can reach equilibrium before the reactants are exhausted. Equilibrium constants and Le Chatalier’s Principle.
Chemical equilibrium is a static condition Students may believe that no reactions are occurring at equilibrium because the net reaction is zero. However, this means that reactions are still occurring—both forward and backward reactions are occurring at the same rate, and no net change is observed. Chemical equilibrium is dynamic.
A candle burning is endothermic, since heat is needed to initiate the reaction Heat is needed at the beginning to initiate, or activate, the reaction. Once activated, the reaction proceeds without further energy input, and releases energy in the form of light. Therefore, it is an exothermic reaction. Another example is heating a piece of magnesium metal in a Bunsen burner, which causes it to combine with the oxygen in the air, releasing a bright light and forming magnesium oxide.
Energy is used up in chemical reactions.

Energy is created in chemical reactions.

Energy is not “used up” or “created” in chemical reactions. Instead, they are released or stored in the form of chemical bonds between atoms.
Miscellaneous
Oil doesn’t mix with water because oil and water molecules repel each other Oil molecules are actually attracted to water molecules more than to their own molecules. This can be shown when a drop of oil, which is originally spherical in shape which minimizes the number of molecules which are not surrounded by its own molecules, is dropped onto the surface of water. When it hits the water, the oil droplet spreads out instead of staying spherical, showing that the attraction between oil and water is greater than between oil and oil. Oil and water remain in separate phases, however, because the water-water attractive forces are still much greater than oil-water attraction. It would require an input of energy for the oil molecules to come between water molecules.
Adding salt to water decreases the amount of time cooking Adding salt to water does increase the boiling point. However, it takes longer for the water to reach this higher temperature (with a constant supply of heat from the stove), and the once the water has reached the higher temperature, the change is so small that it is not significant.
Strength (of acids and bases) and concentration mean the same thing Concentration is the number of moles of solute that are dissolved in one liter of solvent. Strength is the percentage of those molecules that dissociate into ions.

An interesting fact: some weak acids (e.g. acetic) actually increase in strength as their concentration decreases.

Take care when using Electricity

By : A. Ghosh

  1. Safety precautions to prevent electric shock

1)   Careful handling of all electrical equipments.

2)   Damaged leads must not be used.

3)   Broken switches and plugs should be replaced immediately.

4)   All metallic parts of electrical equipments should be properly earthed.

5)   Plug must have its top

6)   All safety devices should be in working condition.

7)   Electric hand tools should be in order at all time

8)   Fuse ratings should be correct.

9)   Respect electricity and do not play with it. It has the potentiality of all dangerous consequences.

  1. Shock and shock treatment

When a human body touches live wire, current flows to earth through the body, causing severe shock and possibly death too. This is because all alternators, transformer, overhead lines are having neutrals grounded.

Method of resuscitation

  1. Holger-Nielsen method (Prone resuscitation)
  2. Mouth to mouth-resuscitation method

Prone Resuscitation. (i) Back pressure—arm lift method (Holger-Hielsen method). There are several methods of giving artificial respiration in the prone position, among which the Holger-Hielsen method is the most common. Here, the victim is made to lie on his stomach with his elbows bent and his hands folded under his head. The person administering artificial respiration kneels down with his left knee opposite the victim’s head and his right foot on the ground, near the victim’s left elbow. He then places his hands on the back of the victim with the thumbs just touching, and gently rocks forward until his arms are almost vertical and he is exerting pressure on the back. The entire movement takes two seconds. The movement causes air to be exhaled

After this, the reviver rocks back gently counting “three” for one second and places his hands under victim’s elbows. The reviver then slides his hands past the victim’s shoulders until his hands can grip the victim’s upper arm near to the elbows. Then he raises and pulls and victim’s arms until tension is felt. This action, which is completed in two seconds by counting “four, five”, causes air to rush into the lungs of the victim

Mouth-to-Mouth Resuscitation. The mouth-to-mouth method assures positive movement of air into the lungs. Therefore this method is preferred when the victim cannot be placed on his back or if he is still on a pole or a tower after receiving shock. The procedure for mouth-to-mouth resuscitation is as follows :

  1. Remove any obstruction from the victim’s mouth.
  2. Place the victim on his back with his head tilted backwards and his chin pointing upwards.
  3. Open your mouth wide and take a deep breath. Place your mouth tightly over the victim’s mouth and keep his nostrils tightly shut.
  4. Blow gently into the lungs of the victim until the victim’s lungs get filled with air.
  5. Remove your mouth and watch for the return rush of air from the victim’s lungs.
  6. When expiration is complete, repeat the procedure until the victim resumes natural breathing.

List of safe practices related to electricity

While working on electricity mind should not think otherwise.

Before energizing a circuit, think about all “clearance”.

Do not disconnect any plug by pulling the flexible cable.

Put off main switch before replacing a blown fuse.

Always be aware of good earthing.

Portable electric equipments, such as drill, must have sound earthing.

File, knife, screw driver etc. must not be used without handle.

Live wire should be provided with switch.

A plier should not be used as a hammer. Sharp tools should not be kept in pocket.

Use sand or dust in case of electric fire. Do not throw water, switch-off electric supply.

Use safety-belt when working on a pole or tower, ladder must be held by another person.

Always add acid to water and not otherwise.

For electric fire use dust, sand carbon dioxide extinguisher or carbon tetrachloride extinguisher.

Dealing with a person in contact with live wire.

Switch off to disconnect person from live wire.

Use a wooden stick to get the victim free. Insulate yourself from the ground, by using a rubber mat, dry wood or clothing and then get the person free.

Send for Doctor and till he arrives, give first aid for resuscitation.

Smoking: A Silent Killer

By: Rajesh Konnur

The ‘puff’ is a simile for smoking. Smoking is dangerous to health. Globally, 4,00,000 people die each year from smoking related illnesses. Newer research findings show that adult smokers usually take their first puff before age 18 and over 3,000 kids become regular smokers each day.

Tobacco will kill one in three young smokers in China, a new study was warned, indicating a worrying trend in an already – ageing society.

According to the publication in Lancet (2015) the study said at least 1 million people in China died of tobacco related causes, the number could double to 2 million by 2030.

China is the world’s largest tobacco consumer and producer and the number of smokers in the country reached the 300 million marks which more than the population of the US by the end of last year.

Beijing has nearly 4.20 million smokers, who smoke nearly 15 cigarettes a day. Among the hundreds of millions of smokers, those below 20 fall in the high risk category, as suggested by the study.

About two- thirds of young “Chinese men become cigarette smokers, & most start before they are 20. Unless they stop, about half of them will eventually be killed” Zhengming Chen , co-author of the study said.

Smoking creates heart diseases, stroke, cancer, emphysema, chronic bronchitis and affects every organ of the body. Smoking is the number 1 cause of preventable death in the US and worldwide.

Quitting smoking is hard. As many as 75% to 80% of smokers say they’d like to quit. But it takes the average smoker five to 10 attempts before successfully quitting.

For some smokers, it’s the little things that motivate quitting. Factors like the smell left on your clothes, the way people react when they find out you’re a smoker, the stains it leaves on teeth…… everyday aggravations that can add up to a tipping point to kick the habit.

Multiple therapeutic techniques help to quit puff. Counseling, self-motivation, nicotine replacement therapy (NRT), on – off line support, social networking, ventilation of the feelings, and adopting healthy life style skills help to quit it.

National Digital Literacy Mission (NDLM)

By: Prapanna Lahiri

India is a country with more than half of its population living in more than 650000 villages spread across the length and breadth of the country. Sadly enough, the country’s impressive economic growth following the opening up of the economy in the nineties, has not benefited the vast rural population of these remote villages. The challenge of the policy planners lied in finding ways to end the isolation of this vast majority of rural population and bring them to be part of the process of modernisation. Digital literacy will make a world of difference to these rural folks, to the farmers and their families. They will be able to research information on fertiliser application and seed selection as well as obtain information about the latest market prices while negotiating the sale of their produce. This would significantly change the plight of farmers who were previously unable to accurately determine existing market prices.

The Digital Saksharta Abhiyan (DISHA) or National Digital Literacy Mission (NDLM) Scheme has been formulated to impart IT training to 52.5 lakh persons, including Anganwadi and ASHA workers and authorised ration dealers, in all the States and Union Territories across the country divided into 3 categories A, B and C. Besides training through government machinery, the scheme also stipulates participation of Industry, NGOs and others using their own resources/ under Corporate Social Responsibility.

Digital Literacy has been defined as “the ability of individuals and communities to understand and use digital technologies for meaningful actions within life situations”. This training aims at transforming the non-IT literate masses into IT literate citizens to empower them to actively and effectively participate in the democratic and developmental process, as also to enhance their livelihood. The vision to initiate the scheme is to empower at least one person per household with crucial digital literacy skills by 2020. The expectation is to touch the lives of more than 250 million individuals over the next few years. The aim of the project is to help adults with low technological literacy, acquire the skills they need to interact in an increasingly digital world.

The IT training envisaged under the NDLM Scheme is designed to be imparted under two levels with the following broad objectives, course duration and eligibility criteria:

  1. Appreciation of Digital Literacy (Level 1)

To make an individual,  IT literate, so that he/ she is equipped with the skill to operate digital devices, like mobile phones, tablets, etc., send and receive e-mails and search Internet for information, etc. Training duration at this level is 20 Hours (Minimum 10 Days and Maximum 30 Days) and the eligibility criteria are Non-IT literate – Illiterate and up to 7th standard pass.

  1. Basics of Digital Literacy (Level 2)

Besides IT literacy (the skills mentioned above), at a higher level the citizen would also be trained to effectively access the various e-Governance services being offered to the citizen by the Government and other agencies. At this level, the training duration is 40 Hours (Minimum 20 Days and Maximum 60 Days) and the eligibility criteria are Non-IT literate with at least 8th standard pass.

Medium of instruction of both the levels: Official Languages of India

Fees: The training scheme provides for financial assistance of 75% of course fees for general category of trainees from both the levels 1 & 2 with balance 25% to be borne by trainees. For trainees from SC, ST and BPL Households in both the levels, financial assistance shall be 100%.

Age of trainees and the Training Centres: All households whereof no member in the age group of 14 to 60 years are IT literate shall be eligible under the programme to nominate one person from their family to be enrolled for training under the scheme in the nearest Training Centre/ Common Service Centre (CSC).

Evaluation: The programme envisages independent external evaluation of skills acquired by learners, by a National level certifying agency like NIELIT, NIOS, IGNOU, etc.

Government of India has launched the ambitious “Digital India” programme with the vision to transform India into a digitally empowered society and knowledge economy. An integral component of the Prime Minister’s vision of Digital India is to make one person in every family digitally literate by 2020.  

EMPOWERMENT OF WOMEN: A SPECIAL STUDY ON SEXUAL HARASSMENT OF WOMEN AT WORK-PLACE AND LAWS RELATING TO SUCH OFFENCE

By: Dipannita Ganguly

“There is no tool for development more effective than Empowerment of Women”

Kofi Annan

 What is ‘Empowerment’?

Empowerment can be referred to as the capacity of the individuals or groups or communities to have control or to have certain degree of autonomy of their circumstances, to exercise their power in order to achieve the goals they wish for and the process by which individually and collectively they are in a position to help themselves and others to synergize their quality of living. Empowerment refers both to the process of self-empowerment and to professional support of people, which enables them to overcome their sense of powerlessness and lack of influence, and to recognise and eventually use their resources and chances. The term empowerment is also used for an accomplished state of self-responsibility and self-determination.

Gender empowerment conventionally refers to the empowerment of women, and has become a significant topic of discussion in regard to development and economics. It can also point to approaches regarding other marginalized genders in a particular political or social context. This approach to empowerment is partly informed by feminism and employed legal empowerment by building on international human rights. Empowerment is one of the main procedural concerns when addressing human rights and development. The Millennium Development Goals and other credible approaches/goals point to empowerment and participation as a necessary step if a country is to overcome the obstacles associated with poverty and development.

The principle of gender equality is enshrined in the Indian Constitution in its Preamble, Fundamental Rights, Fundamental Duties and Directive Principles. The Constitution not only grants equality to women, but also empowers the State to adopt measures of positive discrimination in favour of women.

Sexual Harassment-Concept

In legal terms, sexual harassment is any unwelcome sexual conduct on the job that creates an intimidating, hostile, or offensive working environment. Sexual harassment is any offensive conduct related to an employee’s gender that a reasonable woman or man should not have to endure while at work. The laws prohibiting sexual harassment are gender blind; they prevent women from harassing men, men from harassing other men, and women from harassing other women. Sexual harassment is behavior with a sexual connotation that is abusive, injurious and unwelcome. For the victim, sexual harassment has direct consequences for the maintenance or improvement of her living condition and or places her in an atmosphere of intimidation, humiliation or hostility. Sexual harassment is both sexual and unwelcome. It may be constituted by many or single act and broadly speaking the intention of the harasser is not relevant.

 However, the vast majority of cases involve women workers who have been harassed by male co-workers or supervisors.

The term “sexual harassment” first came into use in the late 1970s in the United States. The term’s origins are generally traced to a course on Women and Work taught by Lin Farley at Cornell University. In 1979, Catherine MacKinnon, a legal scholar from the United States, made the first argument that sexual harassment is a form of sex discrimination prohibited by the constitution and civil rights laws of the United States. Since then many international bodies, national legislatures and courts have prohibited sexual harassment but have not agreed on a universal definition of the term.

There are a few common elements in definitions of sexual harassment worldwide. Generally speaking, behaviour constituting sexual harassment in the workplace must:

(1) Occur in the place of work or in a work related environment;

(2) Occur because of the person’s sex and/or it is related to or about sex;

(3) Be unwelcome, unwanted, uninvited, not returned, not mutual; and

(4) Affect the terms or conditions of employment (quid pro quo sexual harassment) or the work environment itself (hostile work environment sexual harassment).

Kinds of Sexual Harassments

1) Sexual coercion-

  • It is known as quid pro quo sexual harassment in the United States.
  • Sexual Coercion is a type of harassment which has direct results in some consequence to the victim’s employment. It is employment discrimination.
  • Sexual coercion is under a condition of employment, where an openly or implicitly offer in keeping a job or getting a promotion is made by a supervisor to an employee in exchange for sexual favours. Such person normally has the power over promotion or raise of the employee.
  • In sexual coercion, promotion and favourable job benefits will follow if an employee takes the advantage and consented to sex. On the contrary, if the employee rejects, the job benefits are denied.

Quid pro quo sexual harassment occurs when an employee gets on the promotion track or even gets to keep his/her job is based on if the employee submitted to or rejected sexual advances or other types of inappropriate sexual comments. For example, if a supervisor were to tell an employee she would be more likely to be promoted if she dressed sexier, that would be considered quid pro quo sexual harassment. Remember, if an employee submits to the sexual advance or comment, it does not necessarily mean that the employee is then barred from ever making a complaint. If the employee should change her mind, she can still complain against the supervisor who made the comment.

2) Sexual annoyance

  • It is also known as hostile environment sexual harassment.
  • Sexual annoyance is a demeaning and unwelcome sexually related behaviour that is offensive, hostile or intimidating to the victim, but has no direct connection to any job benefits. However, the annoying behaviour creates an offensive working environment which affects the victim’s ability to continue working.
  • Sexual annoyance includes sexual harassment by an employee against a co-employee. Similarly, sexual harassment by a company’s customer against an employee also falls into this category.

This type of sexual harassment occurs when a co-worker or supervisor in the workplace makes sexual advances or comments to an employee that, while not affecting promotions or the future of the employee’s job makes the working environment of the employee offensive and hostile. In general, the comments tend to affect the employee’s ability to do her job. Some instances of hostile environment sexual harassment can be:

  • Personal questions of a sexual nature
  • Vulgarities and other offensive language
  • Physical conduct that is sexual or degrading to any reasonable person
  • Any sexually explicit or offensive pictures or literature that is in plain sight of other employees
  • If the employer was aware, or should have been aware, of the sexual harassment and did not take action to discipline the offender and correct the situation, the employer can be liable as well as the offender.

 International and National Law Relating To Sexual Harassment

  1. The UN Convention of the Elimination of All Forms of Discrimination against Women, 1979:

The UN Convention of the Elimination of all forms of Discrimination against women (CEDAW) adopted in 1979 at Beijing to which India is also a signatory recognizes and also acknowledged that Sexual Harassment is a serious offence and has categorized it as gender discrimination and a form of gender based violence.

  1. The Protection of Human Right Act, 1993:

According to the Protection of Human Right Act, 1993 “human rights” means the rights relating to life, liberty, equality and dignity of the individual guaranteed by the Constitution or embodied in the International Covenants and enforceable by courts in India. Women rights are also Human rights and have to be protected allow them to live with dignity without fear of their safety and security.

  1. The Constitution of India, 1950:

Sexual Harassment of a woman employee at workplace, tantamount to violation of the ‘right to gender equality’ and also the ‘right to life and liberty’– the two most precious fundamental rights guaranteed in the Constitution of India under Articles 14, 19 and 21.

  1. The Indian Penal Code, 1860:

The rape laws in India is wider in comparison to the existing laws on sexual harassment and is to be found under Section 375 and Section 376 of the IPC. The laws on sexual harassment are enlisted under Sections 294, 354 and 509 of the IPC.

 Rules, Regulations and Laws in India in relation to Women Empowerment

A. Role of Legislation

Part III of the Constitution of India “give a constitutional mandate for certain Human Rights-called Fundamental Rights in the Constitution adapted to the needs and requirement of a country……..it also provides a constitutional mode of enforcing them”(Central Inland Water Transport Corporation Limited v. Brojo Nath Ganguly). Part IV on the other hand prescribes the Directive Principles of State Policies. The difference between Part III and Part IV is that while Part III prohibits the State from doing certain things, namely from infringing any Fundamental Rights, Part IV enjoins the State to do certain things. This duty is however not enforceable in Law but the court cannot ignore what has been enjoined upon the State by Part IV.

The relevant Articles of Constitution which provides for women empowerment are mentioned as below:

  1. Article 14: Equality before Law
  2. Article 15 clause (3): Prohibition of discrimination on grounds of religion, race, caste, sex or place of birth; clause (3)—Nothing in this article shall prevent the state from making any special provision for Women and children.
  3. Article 16: Equality of opportunity in matters of public employment.
  4. Article 21: Protection of life and personal liberty.
  5. Article 38: State to secure a social order for the promotion of welfare of the people.
  6. Article 39 clause (a): ……….that the citizens, men and women equally, have the right to an adequate means of livelihood. 
 B. An Assessment of the Practical Scenario

The causes of sexual harassment at work can be complex, and steeped in socialization, politics, and psychology.   Work relationships can be quite intimate and intense, and those involves sharing common interests.  Employees are dependent on each other for teamwork and support, and are dependent on their supervisor’s approval for opportunities and career success. Closeness and intensity can blur the professional boundaries and lead people to step over the line.

Despite laws, government’s plan of action, the international conventions and the claims made by authorities the real picture of legal and social protection is far from theory. The data shows that in every three minutes, one crime was committed against women in India in 2002 and it is expected that the growth rate of crimes against women would be higher than the population growth rate by 2015.

In recent years, there has been an alarming rise in atrocities against women in India, every 26 minutes a woman is molested, every 34 minutes a rape takes place, every 42 minutes a sexual harassment incident occurs, every 43 minutes a woman is kidnapped, and every 93 minutes a woman is burnt to death for dowry. One quarter of the reported, rapes involve girls under the age of 16 but the vast majority is never reported. Although the penalty is severe, convictions are rare.

Despite Supreme Court directives women are still harassed at working place. Social compulsion and legal complexities compel a woman to suffer indignities and torture until she has no other option but to put an end to her life. In most of the cases accused get acquitted because of lack of proper proof.

Thus, in spite of a plethora of progressive and protective legislations favouring women, we have failed in our aims to uplift the social status of Indian women. Proper implementation of these laws will go a long way in curbing crimes against women and improving socio-economic status of women. In view of the atrocities against women – the legislature amended the Indian Penal Code, 1860 (s. 304-B: Dowry Death and s. 498-A: Cruelty) In spite of the amendments and new laws (Domestic Violence Act, 2005) the violence is seen everywhere, even at workplaces.

Theoretically, the victims must complain to competent authority about the harassment, but we have to find out the reason why they fail to file immediately a formal complaint about harassing conduct. Women who reported sexual harassment were perceived as higher in qualities of assertiveness, they too were perceived as less trustworthy and less feminine. Additional result suggests that both men and women thought that members of the opposite gender would derogate the woman if she labelled and/or reported the incident .One of the major obstacles in delivering justice in sexual harassment cases is the poor quality of investigations. The reason behind this is gender bias and inefficiency of the police. Police corruption undermined efforts to combat the offences. In a study conducted by Transparency International it was found that in India the judiciaries are constitutionally independent but this independence is often not reflected in practical terms. So there is a need to make corruption free to all our machinery related to law.

C. Role of Judiciary in Women Empowerment in India

The Sexual Harassment of Women at Workplace (Prevention, Prohibition and Redressal) Act, 2013 is a legislative act in India that seeks to protect women from sexual harassment at their place of work. It was passed by the Lok Sabha (the lower house of the Indian Parliament) on 3rdSeptember, 2012. It was passed by the Rajya Sabha (the upper house of the Indian Parliament) on 26th February, 2013.The Bill got the assent of the President on 23rdApril, 2013. The Act came into force from 9th December, 2013. This statute superseded the Vishakha Guidelines for prevention of sexual harassment introduced by the Supreme Court of India.

Guidelines as stated by Honourable Supreme Court of India in Vishaka v. State of Rajasthan, AIR 1997, SC 3011:

 >  All employers persons imcharge of work place whether in public or private sector, should take appropriate steps to prevent sexual harassment without prejudice to the generality of his obligations, he should take the following steps:

(i)     Express prohibition of sexual harassment which includes physical contact and advances; demand or request for sexual favours; sexually coloured remarks; showing pornographic or any other unwelcome physical, verbal or nonverbal conduct of sexual nature should be noticed and circulated in appropriate ways.

(ii)    The rule or regulation of Government and public sector bodies relating to conduct and discipline should include rules prohibiting sexual harassment and provide for appropriate penalties in such rules against the offender.

(iii)    As regards to private employers, steps should be taken to include the aforesaid prohibitions in Standing Orders under the Industrial Employment( Standing Orders) Act, 1946

(iv)    Appropriate work conditions should be provided in respect of work leisure, health and hygiene to further ensure that there is no hostile environment towards women at work place and no women should have reasonable grounds to believe that she is disadvantaged in connection with her employment.

Where such conduct amounts to specific offence under IPC or under any other law, the employer shall intimate appropriate action in accordance with law by making a complaint with the appropriate authority.

The victims of sexual harassment should have the option to seek transfer of the perpetrator or their own transfer.

 Some Landmark Judgments of the Supreme Court in Matters of Sexual Harassment at the Workplace                                                  

A. Miss RadhaBai v. The Union Territory Of Pondicherry, AIR 1995, 4 SCC 141

In 1973, when Radhabai, secretary to D. Ramachandran, the then State Social Welfare Minister protested against his abuse of girls in welfare institutions, he attempted to molest her; and followed by dismissing her. In 1995, the Supreme Court passed a judgement in her favour, with back pay and perks from the date of dismissal

B. Vishaka v. State of Rajasthan and Others, AIR 1997,SC 3014

 A leading sexual harassment case concerning a social worker (Sathin) in the State Women’s Development Program in Rajasthan who was gang-raped as an act of revenge for her work campaigning against child marriage. Prior to the rape, the women employees had complained of sexual harassment to the State, but no action was taken. The State had no functional policy on sexual harassment and there was a failure of the part of authorities to pursue the case. A public interest litigation was filed by the Lawyer Collective and supported by a number of women’s organisations following which the Vishaka Guidelines emerged in 1997.

C. Apparel Export Promotion Council v. A.K. Chopra, AIR 1999, SC 625

In this case, the accused-respondent tried to molest a woman employee (Secretary to the chairman of a Delhi based Apparel Export Promotion Council) Miss X, a clerk cum typist on 12th august, 1988 at Taj Hotel, Delhi. The respondent persuaded Miss ‘X’ to accompany him while taking dictation from the chairman, so that her typing was not found fault with. While Miss ‘X’ was waiting in the room, the respondent taking advantage of the isolated place tried to sit too close to her and touch her despite her objections; and tried to molest her physically in the lift while coming to the basement, but she saved herself by pressing emergency button, which made the door lift open. On a complaint made by Miss ‘X’ a departmental inquiry committee was set up to investigate into alleged allegations. The Bench said:

“In a case involving charge of sexual harassment or attempt to sexually molest, the courts are required to examine the broader probabilities of case and not swayed away by insignificant discrepancies or narrow technicalities or dictionary meaning of the expression ‘molestation’ or ‘physical assault’… The sexual harassment of a female employee at the place of the work is incompatible with the dignity and honour of a female and needs to be eliminated and that there can be no compromise with such violations.”

 Impact of Sexual Harassment (On Victim, Society and Accused)

Sexual harassment at work can have very serious consequences both for the harassed individual as well as for other working women who experience it second hand. The consequences to the individual employee can be many and serious.  In some situations, a harassed woman risks losing her job or the chance for a promotion, if she refuses to give in to the sexual demands of someone in authority.  In other situations, the unwelcome sexual conduct of co-workers makes the working conditions hostile and unpleasant- putting indirect pressure on her to leave the job.  Sometimes, the employee is so traumatized by the harassment that she suffers serious emotional and physical consequences- and very often, becomes unable to perform her job properly. The consequences to working women as a group are no less serious.  Sexual harassment has a cumulative, demoralizing effect that discourages women from asserting themselves within the workplace, while among men it reinforces stereotypes of women employees as sex objects.  Severe or pervasive sexual harassment in certain types of businesses creates a hostile or intimidating environment that causes women to leave their jobs and look elsewhere for work or discourages them from seeking those jobs in the first place.

The effect on the morale of all employees can also be serious.  Both men and women in a workplace can find their work disrupted by sexual harassment even if they are not directly involved.  Sexual harassment can have a demoralizing effect on everyone within range of it, and it often negatively impacts company productivity on the whole.

The effects of sexual harassment vary from person to person and are dependent on the duration and severity of the harassing behaviour. Thus, individuals can suffer through a number of psychological effects ranging from irritation and frustration to anxiety, stress, and terror. Individuals may fear retaliation and victim blaming. As we are a small community, there can be concern for coming forward and making a complaint for implications to one’s career and academic pursuits. There can be a tremendous fear of retaliation and backlash, not only institutionally, but also to the community of one’s specific discipline or career path.

Some of the potential effects a victim may experience:

  • Anxiety, frustration, depression, sleeplessness and/or nightmares, difficulty concentrating, headaches, fatigue, shame and or guilt, feeling powerless, helpless or out of control, feeling angry towards the harasser, loss of confidence and self-esteem, withdrawal and isolation, suicidal thoughts or attempts
  • Having to drop courses, or change academic plans; it may impact grade performance
  • Increased absenteeism to avoid harassment, or because of illness from the stress
  • Having one’s personal life held up for public scrutiny – the victim becomes the “accused,” and their dress, lifestyle, and private life will often come under attack.
  • Being objectified and humiliated by scrutiny and gossip
  • Becoming publicly sexualized
  • Defamation of character and reputation
  • Stress impacting relationships with significant others, sometimes resulting in the demise of the relationship; equally, stress on peer relationships and relationships with colleagues
  • Impact on references/recommendations
  • Loss of career

Recommendations of the National Commission for Women (NCW) on safety of women in and around College and University Campuses

In response to barbaric sexual violence against three women students in three different places within a week in Delhi University campuses, in 2002, the NCW called an emergency meeting to discuss the safety of women at educational institutions.

Recommendations that emerged out of the meeting, convened by the National Commission for Women with the Principal Secretary (Home), Delhi Police Commission and heads of educational institutions regarding strategies to prevent the occurrence of rape and sexual harassment in and around campuses, are as follows:

Police

  • More PCR vans should be deployed to patrol educational institutions.
  • Along the lines of women’s helplines, college helplines should also be provided and its number should be prominently displayed.
  • There should be police patrols around educational institutions at least for two hours before and after college gets over.
  • There is a need to improve relationships between the police and educational institutions.
  • Every case of rape must be handled by a woman police officer.
  • The attitude of the police needs to be made more positive towards the victim.

Educational institutions

  • Educational institutions must ensure proper lighting in an around their premises, as darkness is conducive to crime. The height of hedges must be reduced in campuses for proper visibility.
  • An internal security committee should be constituted by all educational institutions, headed by the head of the institution, police officer and student representatives who must be invited for meetings to review the security arrangements. If the need arises, other government departments like the PWD, MCD etc. may be invited to review the security arrangements.
  • The internal security committee should have monthly or bi-monthly meetings and must maintain the minutes of the meeting.
  • Experts should be invited to inspect the college area to assess the security needs and arrangements on campus.
  • Educational institutions must perform their administrative role for the security of the students.
  • Students must be given proper training in self-defence.
  • The telephone numbers of women’s helplines must be provided.
  • Entry into educational institutions must be restricted. Entry should be through identity cards.
  • Construction workers should not be allowed to stay on the premises of the institute overnight.
  • Safety gadgets should be provided in hostels.
  • Educational institutions could engage retired police officers on their security committees/boards.
  • Awareness programmes on the safety and security of students must be conducted on a regular basis.

 Media

  • There is a need to sensitise the media regarding the repeated relay of incidents relating to violence against women. This has negative repercussions on society, especially on children.
  • The National Commission for Women directs the media not to intrude on the privacy of the victim.

Conclusion

Sexual harassment at the workplace is a universal problem. Even though the occurrence of sexual harassment at the workplace is widespread in India and elsewhere, this is the first time it has been recognised as an infringement of the fundamental rights of a woman, under Article 19(1) (g) of the Constitution of India “to practice any profession or to carry out any occupation, trade or business”.

Of late, the problem of sexual harassment at the workplace has assumed serious proportions, with a meteoric rise in the number of cases. Surprisingly, however, in most cases women do not report the matter to the concerned authorities.

In India, Articles 14, 15 and 21 of the Indian Constitution provide safeguards against all forms of discrimination. In recent times, the Supreme Court has given two landmark judgments — Vishakha vs State of Rajasthan, 1997, and Apparel Export Promotion Council vs A K Chopra, 1999 — in which it laid down certain guidelines and measures to ensure the prevention of such incidents. Despite these developments, the problem of sexual harassment is assuming alarming proportions and there is a pressing need for domestic laws on the issue.

India is rapidly advancing in its developmental goals and more and more women are joining the workforce. It is the duty of the state to provide for the wellbeing and respect of its citizens to prevent frustration, low self-esteem, insecurity and emotional disturbance, which, in turn, could affect business efficacy, leading to loss of production and loss of reputation for the organisation or the employer. In fact, the recognition of the right to protection against sexual harassment is an intrinsic component of the protection of women’s human rights. It is also a step towards providing women independence, equality of opportunity and the right to work with dignity.

For any sexual harassment law to be successful in India, it is important to be aware of the difficulties confronting our society and ways to overcome them. In India most cases of sexual harassment remains unreported. Women are reluctant to complain and prefer silence due to lack of sensitivity on the part of Indian society. There is a need to gender-sensitise our society so that the victim does not feel guilty and is encouraged to report any form of harassment. The victim’s privacy must be protected. The police and the judiciary, in particular, also need to be gender-sensitised. There should be speedy redressal and an increase in the conviction rate. Women themselves should be made aware of their right to a safe and harassment-free work environment. The concept and definition of sexual harassment should be clearly laid down, and the redressal mechanism made known to women in each and every sector of the economy.
