Adolescent Pregnancy

Pregnancy among adolescents has become a major problem in today’s society and most of these pregnancies come as a shock to these young girls who don’t think about the consequences when they indulge in intercourse. When girls who haven’t reached adulthood and those between the age group of 13-19 become pregnant, it can be termed as teen pregnancy. The number of girls who become pregnant between the ages of 10-19 varies from country to country but either way these pregnancies are not safe or they put both the mother and child at risk. It also has long term implications on them as a person and in the society. Most of the times unwanted pregnancies happen because of coerced sex bringing in a lot of turmoil into the life of the girl.

A positive home pregnancy test after a skipped period confirms the pregnancy and if the doctor also confirms it after a check-up, then it is time for the girl and family to think how to deal with the situation; whether they should abort the child or give birth and raise the baby or give birth and give the baby for adoption. All these are agonizing and harrowing experiences for the girl and her family and to add up to these teen pregnancies carry health risks too. The best way to solve this is to tell the young girls how to protect themselves during sex and prevent these unwanted pregnancies and complications that arise from them.

The best way to avoid pregnancy is to abstain from sex till marriage. In case they decide to have sex, it’s best to be informed on how to avoid unwanted pregnancy. Learn to say NO to boyfriends when it comes to having any type of physical contact, have sex, or have sex without protection.  Know what will result in pregnancy and learn to use the different types of birth control and use them. It is always to visit a doctor and find out in detail because many types of contraception don’t work consistently. Be aware of the consequences and learn to indulge in safe sex and make it an enjoyable experience rather than making grave mistakes and regretting it for the rest of your lives.

Perovskite solar cell

Perovskite solar cell in China
Introducing solar cell
Solar cell is a device that can directly converts solar energy into electrical energy. A basic structure for a solar cell can be demonstrated in Figure 1.

Figure 1. Schematic drawing of a silicon solar cell.
Usually, the n-type is made the emitter layer receiving sunlight. When the emitter layer absorbs enough solar energy greater than the bandgap energy, some of the electrons in the valence band will jump to the conduction band and leave a hole behind, creating an electron-hole pair. When the pair gets close to the depletion region, the hole will get swept across the junction by the electric field while the electron will be pushed away and travel to the load through the metal contact (Figure 2). This process is called collection. The two carriers will meet and recombine at the rear contact, after which the circuit has been completed.

Figure 2. Movement of charge carriers inside a solar cell
However, the electron-hole pair can only exist for a length of time equal to the minority carrier lifetime before they recombine. The distance that the pair can travel during its life time is the diffusion length. If the pair is generated somewhere not close to the depletion region (distance to interface > diffusion length), the electron and the hole will recombine and thus provide no contribution to current generation. Therefore, lowering the chances for recombination can effectively improve the efficiency.
Perovskite Solar cell
Perovskite solar cell uses Perovskite as the light absorbing material. It has ABX3 crystal structure. Because perovskite has relatively lower recombination rate and higher carrier mobility, its carrier diffusion length and carrier lifetime is thus longer, improving the solar cell efficiency. A complete perovskite solar cell should also have HTL (hole transport layer) and ETL (electron transport layer) to facilitate the movement of carriers.
Perovskite, as a synthetic material, has made a big splash since 2009 when it was first tried to be used in photovoltaic power generation because of its excellent performance, low cost and great commercial value. In recent years, the world’s top research institutions and large multinational companies, such as Oxford University, Swiss Federal Institute of Technology Lausanne, Japan’s Panasonic, Sharp, Toshiba, etc., have invested a lot of manpower and resources to strive for early mass production.
In February 2017, Fibrina Optronics broke the world efficiency record of calcium-titanium ore panel with a conversion efficiency of 15.2% for the first time, which was previously held by Japan for a long time. After that, in May and December of that year, they broke the world record three times a year with 16% and 17.4% conversion efficiency respectively. This time, they increased the conversion efficiency of the perovskite module to 17.9%, with a steady-state output efficiency of 17.3%. The results once again demonstrate the technological leadership of Chinese scientists in the field of chalcogenide.

TRUE UNDERSTANDING

“OPTIMISM” what is that? I heard that word first time two days ago. Until I found the word in Oxford English Dictionary. Only I know that. “An optimist finds opportunity in every problem”.

Oh? That’s nice. I evaluate myself as a pessimist who finds problems in every opportunity. I don’t know what is right and what is wrong. I know one thing.Whatever I do .That is wrong. Absolutely wrong. Everyday I ask myself. “Am I get- ting any closer to my goal in my life”?

My answer is always NO . NO ?????. So I realized that I have just wasted a day of my life. One day I came to my classroom. The thought written on the right side of the Green Board struck my heart.

“Great things can be done by great sacrifices only”. It remained on the board for three or four days. But no one took any notice of it.

I asked to myself ,What can I sacrifice for a good thing. How to translate pos- itive thinking into attitude, ambition, and action. I sacrifice a thing which is more and more valuable for my life for the sake of some- thing else. Now I am happy.“Thank God”.

“Happiness is like a butterfly. If we run after it ,it keeps fly- ing away. If we stand still, it comes and sits on our shoulder. Now I forget the mis- takes of the past and press on to greater achievements in the future. But there are other people who cannot enjoy health, because they think they may be sick tomorrow, and stop sleeping in bed when they hear that , more people died in bed than anywhere else. Hoooooooooooo. Now I conclude with the words of Edwin-c-Bliss.

“Success does not mean the absence of failures ; It means the attain- ment of ultimate objectives. It means winning the war, not every battle”.

Communally Yours

India is the single largest stereotypical representation of a country divided on almost every single parameter that forms a part of demography – be it gender, religion, caste or class. It’s not this division in itself that lends India a unique identity, but it is the politicization of these differences that make our country’s different co-existing groups uniquely placed at the cusp of turmoil almost every second day for almost every small issue that would barely ruffle a feather in a simpler, less complex democracy. Be it Varun Gandhi’s remark on cutting the arms of Muslims or Arundhati Roy’s perceived secessionist remarks – motivations that public figures have for flaring the communal set up of the national fabric are diverse, ranging from the need for media airtime compensating for bad policy making and just being a bad politician in general, to satiate certain inner values and inherent notions of empathy for suppressed classes.

 

In this piece I wish to examine the idea of identity and its association with habitation in a community. Is it necessary for us to exist in a society with a diverse set of identities? Why is intuitively assumed that Hindu-Muslim-Sikh-Christians all living together in one nation is the best kind of nation we can have, when history has time and again proved us wrong? Is there any abstract value of the national fabric or the idea of India in isolation to the inevitable clash of civilizations that is bound to happen? Is it possible for a nation state to exist only on the idea of communal homogenization? To be able to comprehend even the more plainer nuances of these arguments, one must drop any notions they have of identity as a tool of defining communal existence. One must reject the notions with which we have been systemically indoctrinated with – that living together is the best possible way; that all identities necessarily must co-exist together.

 

My principle idea is crystal clear – I believe that mere existence of different identities is not the reason for conflict in society. It is only when you assume a sense of utility in cohabitation that you allow the scope for the differences in these identities to turn into conflict. To understand this, let us examine the kind of value that people attach to their notions of identity – be it religious or cultural. Religious beliefs and values are extremely intrinsic to the average religious individual, to the extent that they start to define every single aspect of his life at some point of time – the clothes he wears, the schools he goes to, the food he eats, the person he marries, and the values he espouses.

Parents today irreversibly pass on their religious identities and notions to their children through numerous manifestations of these beliefs in the way they shape their child’s identity. It is essential for a devout Christian to get his son baptised at birth, and for a Jewish or Muslim person to get his son circumcised at birth, or for Brahmins to tie the sacred thread on their child’s body. These ideas are so fanatically manifested in a common man’s mind that they take precedence over everything – either the respect for the law, or the value of even their own life.

The fact that you see Muslims burning French flags for its policy decision to ban burqas or Islamist clerics issuing fatwas against the Swiss administration for banning minarets in the public sphere, or even the mere act of refusing to be frisked at American Airports for the purpose of national security clearly displays people’s association with their religion first and the law of the land later. The fact that devout Muslims are ready to whip themselves to a death like pallor in the name of Allah during Muharrram, or the idea that fanatic Catholics would rather let their lives be changed forever by bearing unplanned pregnancies than resort to abortion supports the assumption that life is considered to be a derivative of God, with religion being his gift to people.

 

The same arguments can be extended to issues like race and class – the only differences being that in these cases, people’s motivations to hold on their identities is based on the idea of self preservation instead of a greater god telling them to do so. Self preservation here implies having a sense of association on the basis of material similarities – like how you look, how much money you have, what the colour of your skin is, what common ancestors you come from, what areas you have traditionally inhabited etc. People attach more value to people who have similar material status and aspirations in society which forms the basis of the race and class divide.

 

Let us now put the above analysis in context of what we’re talking about. When it is clear that one’s  identity is fundamental to an individual, two things happen – firstly, one can begin to appreciate how counter intuitive it becomes to promote virtues like tolerance, respect for all identities, and mutual peaceful existence. Second, (and this explains my assumption that a conflict must necessarily arise out of co-existence of identities), that the politicization of the differences of identity for personal gain or mere empathy is A) inevitable in a democracy where flaring communal set ups to establish vote banks is an important strategy to become an elected representative which is the end goal of all politicians and B) the main reason why different identities are bound to clash when pitted together in the same environment.

 

The final link in my argument is the analysing the causation between the politicization of identities and conflict in society. It is not my burden to prove that every single conflict between identities and communities has political undertones, but my aim is to only prove that politicians in our country have a direct incentive to harp on communal sentimentality to achieve their end of attaining political office, which directly results in a higher propensity towards conflict in a heterogeneous society. The ramifications of the intermingling of identity divisions and politics are analyzed two fold.-

 

  1. A) Politics removes the scope for organic discourse to happen in society to reduce friction between two communities which may be at odds at a particular point of time. Take the example of the Godhra Riots. When the horrendous slaughtering of Muslims first happened back in 2002, it was obvious that there would be a huge divide created between Hindus and Muslims nationally, but more specifically in Gujarat. One would assume that over the years, through awareness drives, government initiative, intellectual engagement in media channels, meetings of representatives etc, a the level of animosity between the two groups would have reduced gradually and organic and hatred would be replaced with acceptance and closure. Yet none of this has happened adequately, because the issue has been picked up by politicians from both sides as a constant reminder to their respective electorates of they are the right leaders to A) exact revenge on the other side (read- Varun Gandhi) and B) instil a sense of pride because on being communally represented, or being represented by one who is from amongst them and of their own identity. This kind of interference with organic discourse hampers communal relations.

 

  1. B) The kind of stature that politicians like Jayalalitha, the late Bal Thackeray, Mamta Banarjee amongst their common party cadre is literally that of Demi-gods, where these people are literally willing to put their life on the line at the beck and call of their political and literal masters. Often this mad ascription to a particular individual and his destructive ideology leads these politically brainwashed sheep to do the worst kinds of things in the name of their leaders, the most glaring of which is inciting riots. (be it the 1984 anti-sikh riots, or the 2002 godhra riots, or the numerous cases of violence by the Marathi Manoos in Maharashtra). The problem in such a scenario is the

inability of legal mechanisms to hold the top level political leaders accountable for motivating and ordering such wrongful actions, as they have a plethora of  disposable young party cadres who have been entrenched with propaganda for years and years just waiting to take the fall in the name of their god in the hope of furthering their own political aspirations and getting an implicit approval from their own personal god.

 

I would do injustice to my ideas if I do not leave you with an idea of what could have been if there was no abstract value attached to an overarching ‘Indian Identity’.  Imagine a society where separate electorates were granted to the dalits at the time of independence, wherein only dalit leaders could stand for election from those constituencies as against the compromise that was eventually reached in the Poona Pact wherein the reservation was given for nomination of candidates and not for their election. I believe there is no legitimacy in the idea that such a move would create a divide in society and isolate other Hindus, because I don’t believe that such a divide is bad thing if it was the only way to have ensured complete dalit empowerment right from that point of independence. Draw a parallel to the black movement – blacks across the world today have embraced their suffering and used it as a source of unity and pride. Their are classes in black majority schools where they are taught about their suffering and suffrage for rights to ignite a catharsis – wherein they think they deserve equal treatment not because they are also humans, but because they’re an identity of their own and that the source of their power is their suffering. It is for this idea of association that many blacks still prefer to live in downtrodden, economically backward areas called ‘ghettos’ in the USA even when the government provides them affordable and better housing elsewhere. It is for this reason that blacks prefer to marry within their own race and live in established black communities. One might argue that this kind of an existence, like in the case of separate electorates for dalits, fuels social exclusion as it isolates them from the rest of the world. But the metric for evaluating exclusion or inclusion isn’t physical as much as it is the psychological evaluation and perception of people’s choices. Social inclusion in these two cases is derived from the fact society as a collective conscience has begun to respect the choices of the blacks worldwide and the dalits in India, recognizing their cohabitation as collective pride and not collective suffering. They respect the fact that dalits and blacks want to marry dalits and blacks only. They respect the fact that dalits and blacks want to live with dalits and blacks only. They respect their cultures more, and society as a whole makes an effort to integrate them as much as possible into mainstream discourse in various forms – be it culture courses in universities, reservations in political as well as normal offices, special privileges given to certain individuals from within their communities, etc. This is a clear indication of how you can promote tolerance and respect even when the physical distribution of your demography is homogenized. In simple terms, imagine an India where states existed on the basis of different religions or cultural identities alone. Then, instead of preaching such values of tolerance and respect to every individual within one state, you would teach them to different states as collectives. There is a greater scope for success in the latter case as A) people will be generally happy with the idea of self representation extended to the highest level and B) politicization of such differences will no longer flare communal or identity differences as homogenization would ensure that, well, there are no two discourses prevailing in one society to clash with each other.

 

Of course, my ideas are fairly radical and may be susceptible to many problems – most of them being unique to the mass homogenization and cultural isolation of people. But that is the beauty of good governance- that there is no foolproof system. Every single system of governance has many fundamental flaws, which signifies the diversity of our nation in the fact that it is impossible to accommodate every single interest at any given point of time or in any one policy decision. But then again, my aim with this piece was not to convince you of the irrelevance of communal cohabitation, but to merely introduce the idea of a counter narrative, that an existence purely on the basis of communal similarities may just be possible, something that 9 out of 10 common men today would intuitively reject.

Globalization and Epidemics

With the ever-expanding globalization and sophisticated transportation networks, the world has become a tighter global village. Human mobility has increased by more than a thousand fold since the 19th century, and the number of people traveling across the world is increasing 10% annually. In addition, economic globalization has helped to increase shipping traffic by more than 27% in the past two decades.

 

In response, international health agencies have taken steps to implement evidence-based health policies to prevent epidemic outbreaks that may result from increased international travel. Continental populations are no longer isolated, and therefore diseases that were once confined to their continent of origin can spread quickly across the world. That is, air and water transport systems have reduced such confinement.

 

For example, the SARS outbreak from a single infected physician from Guangdong spreading to 16 hotel guests in Hong Kong, who in turn spread the disease to other countries such as Vietnam, Canada, and Singapore, led to the spread of the disease to 26 countries, 5 continents, and 8,000 people. This case clearly shows the power of globalization. Another case is the Ebola virus outbreak. The outbreak started from Western Africa, where the disease was rampant at the time. A traveler passing through the affected area got the disease and brought it to the US, making it a pandemic.

 

These cases show that it is impossible to control travel of people and thus that the spread of diseases from a remote location to major cities must be controlled for. Therefore, agencies such as the World Health Organization and the Centers for Disease Control and Prevention should coordinate technical assistance to limit the spread of diseases at the earliest known outbreak.
