Dinosaurs and their descendants

Dinosaurs are ancient creatures, which lived on the earth millions of years ago. What is left of them now are bones which have been hardened over the years called fossils. Fossils are remains of living components, which have mixed with mud and soil. After a period of 6 million years the first humans appeared on earth. Over the years’ technology improved, and life became more and more complicated until today.

It is said that the only living descendants of these magnificent creatures are modern birds. Rumour is that dinosaurs evolved into birds. The first living bird-like creatures were called Archaeopteryx. Archaeopteryx had feathers but couldn’t fly. Instead they resolved to gliding from branches. For example, a dinosaur slowly grew feathers over a period of time. With these feathers they were able to leap from tree to tree. Slowly, these feathers evolved into wings and enabled the dinosaur to glide from one place to another. Over a period of time, these wings became better and the muscles became stronger, and they finally became the first birds. It is good if birds are studied carefully, and if they are, there is a chance that we may find out more about dinosaur bones. With the dinosaurs, there were also aquatic animals.

Today’s sea creatures, such as sharks, whales and fish, are descendants of these ancient aquatic creatures. The people who excavate and study about dinosaurs are called paleontologists. When we reach a higher level of technology, we might be able to extract DNA from fossils and recreate genetically engineered dinosaurs. If we can do this, we can even reverse the extinction of these great creatures.

My Role as a citizen of Earth

Being the citizen of earth there are several responsibilities. My role as a citizen of earth is to protect and save the earth which is most important and necessary responsibility. God has created the earth for human comfort. Humans have to develop friendly relationship with nature and not enmity. If we do not save the earth human life would be over. We should be concerned about the health of our planet and be humble to save the earth. We should save the earth because it’s home for innumerable living organisms.

 

Measures to protect our mother planet earth

 

  1. Avoid pollution:

It’s better to live in a clean healthy environment than a polluted one. Living organisms needs Atmosphere to survive. A gas like oxygen in atmosphere is required for the survival of living beings. Carbon dioxide is also needed to keep the plants alive. Pollution affects the life on the Earth. I will become an air pollution activist by joining local groups that work to avoid air pollution and find a way to get involved in my role.

 

  1. Afforestation:

Plant trees that help to clean the air. Develop forests which will provide habitat for many animals. Plants are also economically very useful. The wood from the trees are used in manufacturing furniture. There are some medicinal plants that are used in Ayurvedic products. Aim to plant trees which will grow taller and provide shade.

 

  1. Maintaining soil fertility:

Protecting the health of the soil by using cloth bags instead of plastic because it takes hundreds of years to decompose; as they decompose some toxins are released into the soil which reduces soil fertility. Use products which are renewable and reusable. Do not use chemical fertilizers it also hinders soil fertility instead use organic manures or bio fertilizers.

 

  1. Work to stop mining:

Blasting operations are planned for mine plan, due to this land becomes unhealthy and landscapes will be destroyed. It also affects the habitat of flora and fauna. Stop mining by being politically active to stop mining in restricted areas of earth.

 

  1. Resource depletion:

Social, economic and scientific developments of country are linked to energy sources. The conventional sources energy being used for long time are generally non-renewable. They include coal, petroleum, natural gas and electricity. We are using them so extensively that their reserves are depleting at a fast rate. At the same time, it is becoming increasingly difficult to discover new deposits. So they should be used in a controlled way.

 

Another problem which I see is poverty. It indicates a condition in which a person fails to maintain a comfortable lifestyle. As a citizen of earth it is our responsibility to contribute our share to ensure all possible ways to overcome poverty. I would try my level best to reduce poverty in my country. If we really want to throw poverty away, we should stop speaking about it and take some measures.

 

Measures to reduce poverty:

 

  1. Donations to poor people:

Donations are the best way to overcome poverty in small scale. I would open my own NGO to help poor people like providing food, clothes, education etc. By paying taxes which helps in the development of nations. Donating to trusted organisations so that it can be used in a useful manner. Live a simple life so that others can also lead a simple life.

 

  1. Educating young people:

Education is the most effective way to reduce poverty. Education strengthens the abilities of individuals and makes them skilled to work and gain income to satisfy his wants.

 

  1. Increase employment opportunities:

Unemployment is a situation in which a person is ready to work physically or mentally at a given wage rate but not getting employment opportunities. Hence increase in employment ensures a comfortable life.

 

  1. Learn about money management:

Savings is a better way for betterment in life of an individual. I would try to save my income by spending money wisely and leading a simple life. I would consult a financial institution to create savings plan.

If all these measures are implemented by all the nations of the world then poverty can be reduced from the whole world.

An Amusing Day

Sometimes our day cannot be as much good as we want it to be. A day when right from the morning we feel like dear lady luck is very upset with us and doing just the opposite of what we want. I recall such a dreadful day of my life. I started my morning by falling off my bed. Apparently I was dreaming about having a sprint with Usain Bolt. Then suddenly a trench came in our way. I jumped, but instead of reaching on the other side of the track, I ended up on my floor. Waking up, stunned by the fall, I noticed that my alarm clock was dead. I had woken up half an hour late. I panicked and quickly went to dress up for my school. While packing my bag I kept getting this gut feeling that I was forgetting something. Then I realized, I have my Chemistry unit test today. In the lazy and joyful weekend that I had spent, I had completely forgotten that my tests would be starting on Monday. In sheer tension I screamed loudly and then out of nowhere a few pillows hit me on my face. It seemed that I had woken up my sister. But I couldn’t care less. I had to rush to the bus stop to catch my bus. By the time I reached there my worst fear had come true, my bus was gone. I had to wait for an alternative as nobody in my house had time to take me to school. Now, at 6’o’clock on a winter morning, finding another bus or auto in my area is like spotting a penguin in a desert (or even harder than that!). The whole area was silent and vacant, most of the people still in their dreams. Somehow I managed to get an auto and after continuously prompting him to drive faster and faster, I reached my school just as the gates were about to be closed. The school coordinator had started giving me his long speech about “the importance of coming on time”, but I ignored him and rushed towards my examination hall.

The exam had already started. To my shock, our batch was assigned the most rude and strict invigilator of the whole world. On entering the examination room, he gave me the speech about “the importance of coming on time” anyway. I started my paper in an instant but soon my interest dried down. It looked like a foreign language test to me, but I finished it anyway. To my relief the exam was over soon and was back in my own class. The very next period, our math teacher came in and asked us to submit our homework. As I couldn’t give it I had yet another scolding from my teacher. As this was not enough, in the games period while playing football someone pushed me and I fell and hurt my leg. Coming back to class tired, hungry and bruised I realized that in my hurry, I had forgotten to pack my lunch in the morning. I felt like banging my head on the table. Irritated, I began to think how someone’s day can go so bad. “Day…bad day….bad day….” I stood up with a start. Today was one of my friend’s birthday. He had invited me the other day for his birthday party in the cafeteria. I thought that I could still have some good moments on such an awful day. Fortunately, it was all well at his birthday party and I had something to eat too. The next period our physics teacher asked for our homework copy. Luckily I had finished that work earlier so I was saved. In the last period our Chemistry teacher came and discussed the paper. As I calculated my marks, I got 16 out of 20 in Chemistry, not bad for an exam I didn’t even study for. I thought “not a bad day in the end at least”. When I went to my bus while returning home, everybody congratulated me on my luck. Everybody told me that in the morning the bus got a flat tyre midway, so everybody had to wait in the cold and were late for the exam anyway. This cheered me up a little bit. Back home, I saw that my mother had laid down a grandeur meal for me as she thought I hadn’t eaten the whole day. Also my father had fixed up the alarm clock, so that I won’t be late again. I couldn’t complain at all. At the end of the day I was thanking my luck for such an amusing day.

This incident made me realize that our story, our day, our life may not have such a happy beginning. But that doesn’t mean it will be like this forever. It’s the rest of our story, our day, our life and the way we chose to lead it that defines how much we have succeeded in life.

Usage of Technology for Educating Children in USA Schools: A Bliss

Technology has changed every aspect of our lives including the education system and the process of learning which forms an integral part of every individual’s life. Inculcation of technology in education has not only reduced the burden of the teachers and students, but has also made the learning process very interesting and easy to understand for the students.

Everyone seems to be fascinated by the usage of technological equipments used while teaching like projectors and smart boards. As per the data, the percentage of computer usage for teaching in schools has almost increased by 80% in the past one decade. Only 18% of public schools in US had computers for instructing the children in the year 1981 which increased drastically to 98% in the year 1991.

Teachers are well versed with the usage of technological equipments who help the students in learning the matter in a better manner. Children enjoy the audio and visual effect of the smart borads used by the teachers for teaching the students. The animations used for teaching various topics add to the interest of the students and makes them more inquisitive to learn more about the topic.

The fact can’t be denied that the inculcation of technology has helped both the teachers and the students. While the burden on the teacher is reduced, the efficiency of the students have also increased with the active learning process.

Now, the teacher is not the center of attention, but she acts as a facilitator or a guide and helps the students in getting the information in a better manner through technological methods. With technology involved in education, the students are more active in their learning. Usage of technology in the classroom gives opportunity to the students to be more interactive during the session and even clarify the parts with the teacher or ask her to repeat the instructions using the smart board.

According to the information provided by the teachers using latest technological methods for teaching students, students showed high level of motivation by learning using technological equipments. The main reason for this was their freedom from the normal classroom setting and the boring lecture sessions which couldn’t retain the attention of the students for a longer duration.

Reading Report of ChapterⅠof We the People

Reading Report of Chapterof We the People

In order to build a better future, American should capture the distinctive spirit of the American Constitution at first. In the first chapter, Ackerman uses the model of dualist democracy to distinguish the connotations of American Constitution with other familiar academic competitors.

. Looking Inward?

Americans have borrowed much European theories to build their constitution. But these theories cannot reveal the distinctive pattern of American constitutional thought and practice.

There is a remarkable breach between constitutional theory and practice at the moment. Though daily political life, citizens get a sound grasp of the distinctions of American democracy. While sophisticated talk, no matter academics or lawyers and judges, uses professional narrative. They fail to capture historical reality or constitutional complexity.

. The Basic Idea of Dualistic Democracy

To demonstrate his point of view, Ackerman begins with illustrating the basic idea of dualistic democracy. The two-track system can best explain the conception of “dualistic.” Two kinds of decisions constitute this system.

One is decisions by the People. This “higher lawmaking” happens only when a political movement earns enhanced legitimacy. So this decision rarely occurs. While decisions made by the government occur daily. The “normal lawmaking”, whose core is ballot, can also prevent elected politicians from exaggerating authority.

However, the brief description of the dualistic democracy can raise many questions. Some suspicions on how institutions of the two-track system can be designed to reach its goal and whether dualistic democracy is the best one arise naturally.

According to these questions, Ackerman then describes specifically in what way dualistic democracy are different from the dominant theories by comparison.

. Monistic Democracy

Ackerman first compare dualistic democracy with monistic democracy.

Though the monistic democracy has a glory history, the root of it is quite simple. Monistic democracy only requires the winning of last general election, which shows the grant of plenary lawmaking authority towards the winner. This makes monists see all institution checks on the victors facing the “countermajoritarian difficulty.” British parliamentary practice is an idealized version of this model, while American democracy is a failure. Rather than granting a single monopoly power, America tolerates insubordinate branches where electoral connection is nonexistent. The practice of judicial review in America also seems antidemocratic.

But it is the monistic question, not the dualistic one that needs critical scrutiny. The monist cannot say one general election is fair enough to claim that they represent the full authority of We the People. There are no effective institutions in monistic constitution to maintain the integrity of higher lawmaking, while dualistic constitutions provide institutions that can effectively block efforts to repeal established constitutional principles.

It follows different opinions on judicial review of the Supreme Court. The monists treat it as antidemocratic. In contrast, the dualists see it as an essence of well-ordered democracy.

. Rights Foundationalists

Then, Ackerman distinguishes right foundationalists with democratic schools and monistic schools.

Ackerman begin with answering criticisms from monists in the view of foundationalists. For foundationalists, having rights means individual fundamental right overweighs the collective welfare. And the “countermajoritarian difficulty” raised by monists is not persuasive for foundationalists, because judicial intervention can restrict the violation from the legislature. Moreover, it is monists’ arbitrary definition of rights that induces thoughtful foundationalists’ understandings of the Constitution.

The dualist’s two-track system of democratic lawmaking can reconcile the conflictions between the monists and foundationalists. But it cannot satisfy the committed foundationalists. Though there are amendments in American Constitution, the higher lawmaking process together with judicial dissent are difficult to be accepted for them. Also, the negative lessons from the American constitutional experience with German-style entrenchment show that the foundationalist interpretation is inconsistent with the existing premises of the American higher lawmaking system.

. Historicism

Ackerman finally turns to Historicism. In this part, Ackerman talks about Burkeanism at first.

Burkean, a third strand of constitutional thought, which is different from common theories, is pronounced amongst practicing lawyers and judges. Burkeans believe that the gradual accretion of concrete decisions is more important than the “high theories.” Though such sentiment contains some insights, the dualist conclusion challenges it in four ways.

The first challenge is that Burkeans ignore the importance of revolutionary reforms during the practice of changing the higher law. Second, they totally avoid the abstract ideals of the Constitution. Third, the rule by the People gives Burkean special trouble. For Burkeans keeps the public dialogue in small elites, including only judges and lawyers. The last challenge is that Burkeans ignore the great Constitutional achievements of the American people.

However, there is common ground for the dualist and Burkean. They both emphasize on the danger of collective irrationality in changing the higher lawmaking in the future. This risk cannot be totally prohibited, but controlled. And there are two ways of it: one is to promote cultivation of citizenship; the other is to transform movements against enemies into productive dialogue.

Another commonality is that they both see the Constitution as a historically rooted tradition of theory and practice. On the contrary, the monistic democrat worships the Present and the Foundationalists escape the limit of time altogether.

Then Ackerman mentions there is a tendency of the revival of republican aspect of the American political tradition. And this allows people to discover the root of dualistic constitution from American political history in a deeper way.

Later, Ackerman talks about the liberalism of Hartz. Although Ackerman agree with Hartz that European models are inconsistent with American politics, he disagrees with Hartz to some extent. Even though America escaped the feudalism, it does not mean that Americans can achieve Lockeanism easily. Moreover, Hartz misunderstand the conception of “born equal.” Actually, American are not “born equal” if they did not struggle against oppression with their political capacity.

The last competing political conception Ackerman compares with is the republicanism of Pocock. His work leads to a deeper republican dimension of American experience. It will help to discover the dualistic theory and practice in the American Constitution and redefine the ideal of self-government. The problem of the impossibility to completely deny the liberalism in some way can explain why this theory is not commonly adopted.

However, Ackerman chooses neither the liberalism nor republicanism. American history has its own cyclical pattern from which we will learn the characteristic of a liberal citizenry.

In conclusion, what Ackerman describes in the first chapter is only an introduction. By contrasting with several competing political conceptions, Ackerman emphasizes dualism’s distinctiveness. He tries to persuade us only the dualism can incorporate all characteristics of American Constitution. The present Americans should follow the dualism to discover their Constitution a living language for self-government.

Are We Using Too Much Antibiotics?

Microorganisms such as bacteria are everywhere, including the human body. Just as the microorganism in a vaccine in small dosages is good for building immunity, being exposed to harmful bacteria in small dosages is good for the human immune system. Antibiotics are the class of pharmaceutical drugs often prescribed to combat bacterial infections but are useless for viral infections. When certain bacteria are exposed to the same antibiotics over a long period of time, the medicine can become useless over time. The last three decades have witnessed nearly a 50% increase in prescription of antibiotics across the world.

This raises the question of whether too much antibiotics are being used.

Hospital prescription of antibiotics accounts for 20% of usage, and the rest is through self-medication in countries where antibiotics are available over the counter. Some residents of the Philippines use antibiotics for tuberculosis for their children. Studies show that the use of too much antibiotic during infancy and childhood can lead to permanent reduction in good bacteria such as Bacteroides spp. and a permanent increase in bad bacteria such as Enterobacteriaceae in the gut, which develop antibiotic resistance quickly.

The direct impact of increased antibiotic use and consequent antibiotic resistance can be increased mortality rates. For example, Clostridium difficile associated disease (CDAD) is also wreaking havoc due to antibiotic resistance.

To combat the rampant usage of antibiotics and prevent antibiotic resistance, organizations such as the World Health Organization (WHO) and CDC have developed stewardship and awareness programs to educate the public regarding the appropriate use of antibiotics and harm in overusing them. But much more is needed to address this increasingly serious healthcare issue.

Deforestation to blame for Beijing’s pollution

Deforestation to blame for Beijing’s pollution

Near the Mongolian Plateau where in hills and plains are present all around, Beijing is experiencing a maximum temperature which cause pain to the people. The sandstorm which came from the Gobi desert conquers the urban area every year during spring season. The whole city is full of dust and becomes grey, painting the lives of the people.

Almost every year during that season, people are experiencing the dusty season and they usually wear mask and cover their head in order to get rid of the dust.

Deforestation results to a great destruction and deteriorate the soil and can cause sandstorm. Some areas are affected by deforestation by making rice fields into sandy seashore and agricultural land into wetland.

image007

Deforestation not only decreased the volume of water resources but it also the reason why sandstorm exist that destroyed tens of thousands of hectares of agriculture land, widening the desert land.

The solution to the deforestation is not only by preventing private vehicles and public vendors and removing private factories. The government of China must make an effort to completely stop illegal logging, huge irrigation and other building of infrastructure that ruin the existing forest and the community.

Beijing no longer needs a large bypass encircling a town and tall buildings. Instead, Beijing requires a green belt. Financial support is even more effective to help addressing the problem in pollution and to make the sky to its natural color.

RCT AI for Game Industry

RCT AI is a team focusing on developing AI solutions for game industries. According to the official website, the solutions is based on an algorithm called “Chaos Box”. Based on the engine developed on this algorithm, in-game NPCs’ behaviors and scripts can be generated real-time instead of manually input into the program, which provides NPCs the ability to appropriately respond to human players’ actions in the real-time. In the early demo showcase videos posted on Bilibili by RCT AI team, a scenario of bank robbery is created. All NPCs appear in the scenarios are programmed with AI engine with “Chaos Box”. NPCs are all appropriately respond to human player’s different actions on a single plot without any scripts input. The scenarios go on fluently without any errors happen on NPCs and end up differently based on different moves by human players. Apparently, by applying this AI engine into the video game programs, all the games include NPCs or bots are going to be changed. One benefits for video game players is they won’t need to tolerate NPCs acting weird. That means the gaming experience is not going to be destroyed by error in the algorithm and the immersion of video games will go to a higher level. However, a concerning problem for a real AI system like this is about the self-learning of AI. The AI will be trained in excessive amount of experience being human players’ opponent. It is very possible and assured that some day in the future after AI engine is applied into the game, the NPCs in-game will be trained into an extremely difficult opponent for human players to defeat and totally ruin the game experience. A system of restricting AI learning process should be applied in order to protect video game player’s gaming experience.

Music piracy in Japan: a growing problem?

Music piracy in Japan: a growing problem?

We are all aware that music piracy is global problem today, but not the same as another in different countries and regions. Japan is also experiencing a problem about music piracy. It is roughly calculated that there were nearly four hundred million pirated music files that were downloaded and additional seventy million compared to the number of the legal downloads, which lead in telecom and music industry in Japan to enforce “a system to automatically check cell phone Web sites for illegal music files, in order to prevent the files from being uploaded or downloaded in breach of copyright law.”

The Japanese have come up with new methods to observe and check the progress of the users’ use of technology, without a doubt was enhanced by the fact that it is a leading country in technological progress. Probably, it has also become fully aware that taking legal action in opposition to users will lead in a strong and adverse reaction that can possibly paralyze the industry, something foreign companies are only beginning to understand.

After all, the most important thing is the recognition and enjoyment of music. While fans are searching for novel ways to achieve their chosen tunes illegally, musicians and record labels should still be delighted that there are music lovers and be grateful that there are still supporters who are ready to support them through buying their albums. The Japanese have a plan  that can possibly prevent illegal downloads from happening, and that obviously, is always an asset.
