The Timeline of Social Media

As millennials or members of Gen Z, most of us have been exposed to some form of social media from quite a young age. Our parents’ generation saw social media begin its growth, we grew up with it, and the coming generation is not going to know a life without it. So, where did it all start, and how did we reach here?

Precursors:

In simple terms, social media refers to computer-based platforms that can be used to share thoughts, ideas, and information through the internet. It gives users quick electronic communication of content, such as personal information, documents, videos, and photos.

But before the internet, there was the Morse Code as a precursor to the social media we know of today. Morse code used a series of dots and dashes which were tapped out by hand on a telegraph machine to communicate some information. The first message using Morse code was sent on 24 May 1844 from Baltimore to Washington D.C.

The emergence of ARPANET (Advanced Research Projects Agency Network) in 1969 by the United States Department of Defense and NSFNET (National Science Foundation Network) in 1987 by the National Science Foundation was crucial for laying the technical foundation of the Internet.

The Timeline:

With the advent of the Internet, there were a lot of communication services coming up in the U.S such as CompuServe, America Online, and Prodigy. They provided users digital communication services through email, bulletin board messaging, and real-time online chatting. But the first online social media is considered to be Six Degrees which was the first platform that made it possible for users to have a profile. A profile is like a virtual character that resembles the user’s identity. Six Degrees was developed by Andrew Weinreich in 1997 and the name was derived from the “six degrees of separation” theory according to which “everyone in the world is connected to everyone else by no more than six degrees of separation”. This platform was shut down in 2000 but is now active again and you can find it with a simple Google search!

A lot of instant messaging applications came up between 1997 and 1999, like AOL Instant Messenger, Yahoo Messenger, and Microsoft’s MSN Messenger. Brad Fitzpatrick founded LiveJournal which caused a large number of people to get into blogging.

Friendster was another platform that was launched in March 2003. It allowed users to contact other members, maintain those contacts, and share online content and media with those contacts. Users could share videos, photos, messages, and comments with other members via profiles and networks. it was redesigned as a social gaming platform in June 2011.

Both LinkedIn and MySpace were launched in 2003. LinkedIn was founded as a networking site for career-minded professionals and still remains the social media site of choice for job-seeking people as well as employers looking for qualified professionals. MySpace allowed users to share new music on their profile pages and was the most visited website on the planet by 2006. It was beaten in popularity by Facebook in 2008, which has now grown into a huge networking service that literally everybody knows about.

Modern Social Media:

Facebook was founded in 2004 by Mark Zuckerberg and his Harvard collegemates and gained popularity over other social media sites because it provided frequently updated content in their News Feed. “The Wall” feature also enabled its users to post publicly. The “Like” button was introduced in 2009 and “The Wall” was replaced by the “Timeline” feature which organized the user’s posts chronologically. Over the years, Facebook has also been the subject of various controversies, including issues related to user privacy, mass surveillance, and political manipulation. The platform has 2.8 billion active monthly users, as of 2020.

Steve Huffman launched Reddit in 2005 as a web-content rating and discussion website where users can vote content up or down. In 2006, Jack Dorsey launched Twitter as a microblogging site where users can post and interact with messages known as “tweets”. As of 2020, Twitter has 186 million active users.

Instagram is another big social media site that was launched in 2010 by Kevin Systrom. It was launched as a photo-sharing website but has now included sharing of media content that can be edited using filters and featuring hashtags. Viewers can like, browse other users’ posts, and view trending content. Instagram was purchased by Facebook in 2012. It has since then come up with several features like messaging, ‘stories’ and live-stream features, and ‘reels’ which allows users to post quick 15, 30, or 60-second video clips. It is said to have 1.386 billion active users as of 2022.

Pinterest was launched in 2010 by Ben Silbermann as an image sharing and social media service site. Users can save and find information using images, GIFs and animated videos. Snapchat is another popular site that was launched in 2011 by Evan Spiegel. Instagram developed its ‘stories’ feature because of the competition from Snapchat which allows users to post pictures and messages that are available only for a short time.

Other popular social media platforms include TikTok, which was founded in 2016 by a Chinese company called ByteDance. Users can post very short videos on the site and it has rapidly grown to be hugely popular among teens and young adults across the world. As of 2021, it has about 1 billion users, even though it has been banned in various countries due to issues with content and security.

Over the years, social media has grown from being a place for people to connect with friends and family, to also being a major platform for businesses and corporations. Sponsored advertisements have been a part of all the modern social media sites like Facebook, Twitter, and Instagram. Companies use organic social media marketing to increase brand awareness, develop and nurture relationships with customers, generate leads and increase conversions, and learn from competitors. Social media sites like Facebook, Instagram and Twitter also regularly come under fire for spreading fake news, and causing psychological effects like addiction, and self-esteem issues in teenagers and young adults.

The landscape of social media is rapidly changing and we can only wait and watch how this industry grows and changes in the future.

YONKERS POWER PLANT

Located seven miles north of the Island of Manhattan stands the ruin of the Glenwood/Yonkers power station associated with the New York Central and Hudson River Railroads. Built as a result of an act passed after 1900 to electrify the urban railroads of New York, the plant was designed by Minnesota-based architects Reed and Stern. Due to the infancy of electrical transportation power, the New York Central and Hudson River Railroad leadership commissioned the architects to build two power plants: the Glenwood/Yonkers plant and its sister plant in Port Morris of the Bronx.

The decline of the Glenwood plant began in 1936 when the New York Central Railroad began buying its electricity rather than producing it. This change proved to be more efficient and economical than producing electricity at separate railroad power plants. The plant was sold to New York’s Consolidated Edison and continued to produce energy until its decommissioning in 1963. Shortly after its closure, the large turbines and boilers were broken down and scrapped. The majority of circuit boards, furniture, and other generic pieces were left behind. Over time, the remains of the plant slowly disintegrated into a mid-20th century urban industrial ruin. Some walls have collapsed into piles of bricks. The remaining graffiti-adorned standing exterior frames smashed windows and a blighted interior.

Here is how it stands today: a monument to the decline of industry along the Hudson River.

The main generating building is split into two halves: the turbine hall and the boiler room. The turbine hall presents an early 19th century French arcade ambiance with its vast open middle that is surrounded by four floors of walkways topped with a giant glass roof. A historical impression is sensed from the structure’s untouched architecture and objects. The main turbine hall is amazing due to its immense size and Piranesi-like walkways and staircases. Its spectacular all-glass ceiling allows vast amounts of light into the great hall and evokes early steel construction design, a time when structure became longer and taller and took on lightness in its architecture. The astonishing glass ceiling has endured more than a century of time.

South of the turbine hall is the boiler room, an area that has unquestionably seen better days. The majority of the boilers have collapsed, producing a long hallway bordered by giant cross beams and piles of bricks. Desks, cubbies, shoes and hangers remain in their original resting places, covered in layers of mud and dust.

To the north of the main generating building is the substation that was turned into some sort of catchall. This building, while not as arresting as the generating building, contains many offices, bathrooms, and locker rooms. The highlight of the substation is its roof access. The roof heralds a beautiful view of the Hudson River as well as a bird’s eye view of the power plant grounds.

We hope this adventure is as stimulating for viewers as it was for us. A word of caution for those who wish to visit: wear comfortable boots and gloves when exploring the fallen plant, even on a beautiful day. Explore at your own risk. And officially, we can’t tell you how to trespass onto the property but if you get off at the Glenwood Metro-North Station you’ll be able to figure it out.copywrite GOOGLE

For Adult Survivors Of Childhood Sexual Assault, AB218 Is A Chance For Justice

On January 1, 2020, the state of California took a bold step in confronting the epidemic of child sexual assault when it enacted Assembly Bill 218 (AB218).This landmark bill took on the problem in three major ways — it broadened the definition of child “sexual abuse” to “sexual assault”; it extended the civil statute of limitations from age 26 to age 40; and it allowed for a three-year “lookback window” for those who had suffered sexual assault as a child but missed the prior statutory deadline.The deadline for filing claims under the three-year lookback window is rapidly approaching. It’s an important opportunity for anyone across the nation who suffered sexual assault in California decades ago to finally seek justice for the abuse they endured, as well as help others who have suffered like they have.A Major Step ForwardAB218 represents a major step forward for the state of California in recognizing the seriousness of the problem and its long-lasting impact on the victims. By relabeling what was formerly known as “sexual abuse” to “sexual assault,” it helps to emphasize what a serious and damaging crime it really is.This new definition not only more broadly defines what constitutes sexual assault, it also allows victims to sue organizations such as school districts, clubs and membership organizations, religious organizations and others for these crimes. What’s more, those organizations that are found to have been involved in covering up sexual assault can now be subjected to triple the damages than they were before the act was passed.And by extending the statute of limitations to age 40, the bill takes on one of the most important roadblocks that prevents victims of sexual assault from obtaining justice, which is that unique combination of social and psychological factors that deter many victims from coming forward until they have reached adulthood.Courageous ActionsStudies have shown that child sexual abuse is committed most often by a trusted adult, whether a clergy member, teacher, coach, adult family member or other person close to the child.Many times, when a child or adolescent is sexually assaulted, the predator will use a combination of threats and/or psychological manipulation to keep the child silent.And sadly, in many cases, if the child is brave enough to come forward, they are met with disbelief or told to keep quiet by a parent or authority figure.Furthermore, in many instances, the child may block out the memory of the trauma and not recall the details until much later in life.The truth is that most victims of childhood sexual assault don’t have the courage to come forward until they are well into adulthood. In many cases, they may not know that what happened to them was in fact sexual assault, due to their age and trust of the person who perpetrated it. In fact, a recent study suggests that the average age that victims feel comfortable in coming forward with the details of their assault is 52, by which time the statute of limitations has long since passed.Fortunately, the AB218 lookback window offers a new opportunity for those who suffered sexual assault during their lifetime to get the help they need and to finally get justice. There are a number of resources and attorneys who advocate for sexual assault survivors, including attorney Raymond Boucher of Boucher LLP (www.boucher.la) in Woodland Hills, Calif.Boucher has dedicated much of his practice to helping victims of child sexual abuse and assault, including bringing in over $1 billion in settlements for victims who were sexually abused by Catholic priests. He is a fierce advocate of legislation such as AB218 and encourages victims, regardless of age, to come forward to take advantage of the unique lookback window for claims.”Those individuals who decide to come forward and pursue their case under the AB218 lookback window are courageous and selfless pioneers who not only seek justice for the lifetime of pain they endured but are forging the way for others who are suffering like they did, and are paving the way for meaningful change,” says Boucher.

Neeraj Chopra- The Golden Boy of India

07th of August, 2021; as the flag was getting higher and higher, and after a few moments; the beautiful hymn- Jana Gana Mana, was played, every Indian had goosebumps and water in their eyes. One day before the closing ceremony, when almost all hope was lost, Neeraj Chopra with a massive throw of 87.58m, brought a gold medal to out country. India had shined at the Olympics this time bagging a total of 7 medals, compared to last times 2, which has already raised hopes for the next Olympics. Till date not even a single Indian has won a gold medal at the Olympics for athletics. By winning a gold medal, Neeraj carved his name into our history books. In the coming years, when students will hear his name, not only will they remember the achievements he has done or yet to, but also this 23 year old young lads inspiring journey to the Olympics.

How many of you know, that unlike PV Sindhu or Mirabai Chanu, our Neeraj Chopra is not a full time athlete. He is currently in the Indian Army and holds the position of Naib Subedar. One great lesson that we can learn from Neeraj aside from his great skill would be balancing. He balanced his career and sports, not lagging behind anywhere. But a decade ago, if you were to meet this lad, you would be surprised to find him that way. An obese kid from Panipat, who was very mischievous and also often ridiculed by his friends for weighing 90 kilos and looking like a sarpanch aka a village head, Neeraj had started to hit the gym to reduce his weight. He used to visit a gym at Madlauda, cycle 24 kilometers to and fro to reach it. He was the youngest member at the gym and he later shifted to a gym at Panipat. Here, he used to visit the Panipat Sports Authority of India, and the magic happened here. Jaiveer Singh, another Javelin thrower found the potential and skill in Neeraj Chopra, when he was able to throw the javelin for more than 40 meters that too without any prior coaching or knowledge. After this incident, Jaiveer started coaching Neeraj Chopra for Javelin throw. After an year of training from Jaiveer, Neeraj headed to Panchkula, four hours away from his home to train for Javelin and his maximum throw now was about 55m. His coach Naseem Ahmad, described Neeraj to be a very attentive student who took notes about how to be better from other players and asked more questions than usual. After this he went on the achieve a new national record a throw of 68.40 meters. Soon there was no turning back and for each competition Neeraj started to shine even better than usual and soon was throwing more than 70 meters. He had won many golds at prestigious competions like the Asian Games, Commonwealth, South Asian Games, Asian Championships, World Junior Championships and the historic recent Olympics. He has also bagged a silver medal at the Asian Junior Championships. Neeraj Chopra indeed still has a lot more to see and win, but at such a young age, he inspired and made many people proud and will continue to do so. Something that we all shpuld learn from Neeraj Chopra would be, “Dream Big, Work Hard, Stay Positive and Enjoy the journey.”

Service Sector in India

The service sector is the quickest and the largest developing sector in India, it also has the highest productivity of labour and is predicted to keep developing at a faster rate. By providing employment, intensifying investment and advancing infrastructure, the service sector can contribute greatly to economic growth. It is significant for a growing country such as India with a huge population to provide standard employment and cope up with the development. Private funding is needed for services of configuration which includes telecommunications, energy and transport.

In India, there are various service sectors that signify and execute robust prospects for the upcoming development in economic field.

Fintech/ IT-BPM: The biggest component of ITs is export. The growth potential is around 10-15% per annum and the gross value addition provided by sections of Fintech and IT/ITs is above $ 155 billion. Till now, low-priced investment of labour was beneficial in countries, where mainly English is spoken. In order to expand the growth, the sections of IT/ITs are required to make subsequent changes by upgrading from a ‘service provider of low-value addition’ to a ‘service partner of high value addition’. IT companies can provide Fintech measures to intercontinental pecuniary clients by upgrading their skills to the maximum extent. The high value addition services provided by India to international clients are all sorts of services related to pecuniary risk, indemnity, refunding and management of circumstances beyond human control.

Tourism and Healthcare: Healthcare industry’s contribution is expected to reach $ 372 billion by 2022. The accessibility of elite proficient doctors, healthcare facilities, medicinal etc has greatly added up in the development of the service sector. By 2022, the Indian government is intended to increase Medicare by contributing 3% to the gross domestic product (GDP). In this Covid pandemic, two vaccines, namely Covaxin and Covidshield have preserved the population of India, including a number of countries as well.

The tourism industry in India is expected to reach $ 488 billion with a contribution of about 9.2% to the Indian economy in total and about 39 million jobs were offered from this sector in FY20. After the pandemic is over, topographical tourism is expected to come in light for the tourists of Asian countries in the south. Free loans by the government are provided to MSMEs in order to deal with the post crisis of the pandemic and resuscitate the tourism industry.

Transportation and Logistics: In India, the extensive meshwork of rivers and coastlines gives rise to extensive back and forth competition to services related to logistic and transportation. These services include warehousing, e-logistics, the port service, abroad trading etc. By 2032, the logistic industry is expected to reach $ 360 billion.

By 2022, the government has targeted the construction of 65,000 km of national highways at a price of about $ 741.51.

Space: Globally, India made a record of launching the highest number of space satellites. This could only be possibly done by the powers sustained from other spaces. Skilled experts in various technological sections of the launch plan have made possible such advancement in the industry of space transportation over its worldwide associates. The launch competence is nearly 100% in the record. Great developments can be seen in this field, but more improvement can be made by further building measurements in non-military and military implementations.

How Atomic clocks are so accurate?

Most types of clocks rely on the oscillation of a slid body, be it a pendulum, a balance-wheel, or a quartz crystal, but each suffers from the effects of temperature, pressure, and gravity. Time measuring devices depended on the spin of the earth, but these suffer from seasonal effects and tidal friction. The moon causes tides to occur on earth and it causes friction between moon and the earth. This friction slows down the earth’s rotation by few milliseconds. This is called tidal friction. The atoms, however, vibrate a fixed number of times per second. Both the U.S. National Bureau of Standards and the United Kingdom’s National Physics Laboratory tried to take advantage of these vibrations.

Four atomic clocks are used in each of the many satellites of the global positioning system and comparisons of electromagnetic-wave travel times enable positions of earth to be measured very precisely. The clocks are also used by geophysicists to monitor variations in the spin rate of earth, and the drifting of the continents. Since record began, earth recorded the shortest day on July 19, 2020, when the day was 1.4602 milliseconds shorter than 24 hours.

In 1949 the Americans built a quartz clock that was synchronized by the 24-GHz vibrations of low pressure gaseous ammonium molecules. The British, under the leadership of physicist Louis Essen (1908-1997), used the oscillations of an electrical circuit synchronized to the vibrations of caesium atoms, the first caesium was kept in a tunable microwave cavity and the clock relied on the fact that were 9,192,631,770 transitions between two hyperfine ground state energy levels every second. This number defined the second, as opposed to the old definition of there being 86,400 seconds in one day. A good atomic clock was accurate to one part in 1,014, and therefore would take about 3 million years to lose or gain a second.

Why atomic clocks is used in GPS?

The Global Positioning System (GPS) consists of 24 satellites orbiting the earth. A GPS receiver uses the position of four of these satellites to locate itself. One to correct the time on the receiver, and three to locate its position. A signal is sent to the receiver from the first satellite that contains the satellites location and the signal’s time of departure. The receiver then multiplies the signal’s travel time by the speed of light to calculate its distance from the satellite. With one satellite the receiver knows that it’s located o a sphere around that satellite with a radius equal to the calculated distance. So, it does the same calculation with a second satellite. The intersection of these two spheres narrows the location to the circumference of a circle. Then with a third satellite, the receiver can reduce the location to a single point. Since signals are travelling at the speed of light, being off by even a millisecond means an error off about a million feet, or 300 kilometers. But with atomic accuracy, the receiver can locate itself to about 3 feet. Global Positioning System (GPS) satellites fly in medium earth orbit (MEO- Medium Earth Orbit) at an altitude of approximately 20,200 kilometers from ground.

The NIST-F1 is one of the most accurate time standards based on microwave atomic clocks. The most accurate atomic clocks lose about a second over 138 million years.

PHARMACOVIGILANCE: NEW INSIGHT IN PHARMA FIELD

Pharmacovigilance support safe and effective use of drugs.the safety concern of drugs now becoming priority of area.In developing countries drug safety is more focused area. Here is detailed information about role of pharmacist in pharmacovigilance.

According to WHO ” pharmacovigilance is the science and activities relating to detection, assessment, understanding and prevention of adverse effect and any other drug related problem.” Let’s see how pharmacovigilance work? And also the role of pharmacist in pharmacovigilance. It contains various steps such as adverse event Reporting, individual Case Safety Report, medical coding, aggregate reporting, signal detection and risk management.

  1. Adverse case management- It is the first step where Adverse event is reported in various platforms such as hospital, regulatory agencies, review of manufacturing company. After reporting validation of event is done by using 4 parameters that are – patient, product, report, adverse event.
  2. Individual Case Safety Report- When the event is validate then individual safety report is created.here special/ separate report of adverse event is made by detail study of patient and product.
  3. Medical coding- The ICS report come to medical coding to create medical report. The translation of medical report into short code used in healthcare industry is called as medical coding.
  4. Aggregate reporting- It is the process of compilation and submission of aggregate report to regulatory agencies over the period of the product life cycle.there are various types of aggregate report such as DSUR, PSUR etc.
  5. Signal detection- the process of actively searching for and identifying safety Signal from wide variety data source. It done in two ways – qualitative and quantitative.
  6. Risk management- Drug undertaken to promote safe use of medicine and safeguard health of patient. Risk: Benefit ratio is calculated and depending upon that drug given in market or withdraw from market.

In each step of pharmacovigilance there requires good knowledge of drug use , it’s formulation and detailed analysis of Adverse event. The pharmacist know drug in all way so he/she has better understanding ability of adverse event than any other healthcare professionals. There are various drugs developed regularly and they also has some side effects. To avoid that effect and giving better life to patient is most important. pharmacovigilance is essential field for drug safety. That’s why it is new insight in pharma field.
