1. Government Blogging

We normally see blogging as a two-way interaction, in which the blogger creates the content and the readers interact or challenge the author.


But the case will be much difficult when it comes to government, such as the  White House.


Because people will become more coarse and ride online, especially in the comment area.


Hence  the governor blog may go wild and chaotic.


So the government will have to administrate the comment.


Once the government starts administrating the comment, citizens may find the government manipulating what should be said and what should be shown,  which contradicts the original intention.

3. Life expectancy and carbon footprint



各个国家应该记录它们的carbon footprint,过去寿命超过65岁的人口是百分之多少,现在是多少,2030是多少,美国是多少,德国是多少(数字不记得了),然后在20XX年,人类需要two  extra planets满足需求。


1. Orbital Debris

For decades, space experts have worried that a speeding bit of orbital debris might one day smash a large spacecraft in to hundreds of pieces and start a chain reaction, a slow cascade of collisions that would expand for centuries, spreading chaos through the heavens. In the last decade or so, as scientists came to agree that the number of objects in orbit had surpassed a critical mass or, in their terms, the critical spatial density, the point at which a chain reaction becomes inevitable they grew more anxious.


Early this year, after a half-century of growth,the federal list of detectable objects (four inches wide or larger) reached10,000, including dead satellites, spent rocket stages, a camera, a hand tool and junkyards of whirling debris left over from chance explosions and destructive tests. So our billion dollar of satellites are at risk.


2. Food and eating in Australian

In the past two centuries there has been a dramatic change in the role of food and eating in Australian public consciousness. Public discussion of food was largely confined to matters of supply, distribution and price. Towards the end of the nineteenth century some newspapers were offering regular columns of advice on house keeping topics, including menu planning and recipes. However, eating remained essentially a private activity, even when undertaken in company.


By the late twentieth century, food and eating had become prominent public preoccupations.Evidence of this dramatic cultural revaluation abounds. In bookstores, for example cookery and all things related to it are often among the larger displays. 


There are specialty stores selling all manner of cookware, table ware and other paraphernalia associated with food, eating and drinking.

Perhaps most telling is the extension of the phenomenon of mass media celebrity to include culinary personalities. Scholars, too, have jumped on the com-modification bandwagon. Now degrees in gastronomy seem set to emulate the MBA phenomenon of the 1980s and food has become a respectable subject for investigation with philosophers, sociologists, historians, cultural theorists, ecologists and many others all having a go at it.


However, surprisingly, the question seems to have held little fascination for most historians. For the best part of two centuries they have managed to write their accounts of colonization and nationhood with only scant reference to how the settlers and their descendants fed themselves.


3. Electric eels.

On a field trip to the Amazon in 1 807, 1 9th-century explorer Alexander Von Humboldt witnessed a group of horses lead through a muddy pool filled with electric eels, which he described as dramatically leaping up to attack the intruders. But scientists have doubted the story. An illustration of Alexander Von Humboldt's story of the battle between the horses and electric eels.


The first time I read Von Humboldt's tale, I thought it was completely bizarre, Catania says.Why would the eels attack the horses instead of swimming away? But then he observed the same behavior by accident as he transferred the eels in his lab from one tank to another using a metal-rimmed net. Instead of swimming away,larger eels attacked the net by leaping out of the water.


Catania tracked the strength of the eels electric shock by attaching a voltmeter to an aluminium plate, or conductive metal strips to predator objects such as a crocodile head replica.The zap a submerged eel distributes through the water is relatively weak when it reaches the target.

But when an eeltouches it with its electricity-generating chin, the current travels directlyto the target and has to travel through its body before it gets back to thewater, Catania reported in Proceedings of the National Academy of Sciences.


This allows theeels to deliver shocks with a maximum amount of power to partially submergedland animals that invade their territory, Catania explains. It also allows themto electrify a much larger portion of the invaders body.


Catania found the eels leapt to attack, ratherthan receded, more often when the water in the aquarium was lower. He arguesthe attack lets electric eels better defend themselves during the Amazon dryseason. When they're cornered in small pools and make easy prey.


4. Overqualified worker

If yourrecruiting efforts attract job applicants with too much experience a nearcertainty in this weak labor market you should consider a response that runscounter to most hiring managers MO: Don't reject those applicants out of hand.


Instead, take acloser look.New research shows that overqualified workers tend to performbetter than other employees, and they don't quit any sooner. Furthermore, asimple managerial tactic empowerment can mitigate any dissatisfaction they mayfeel.


The prejudice against too-good employees is pervasive. Companies tend to prefer an applicant who is a perfect fit over someone who brings more intelligence, education, or experience than needed. On the surface, this bias makes sense: Studies have consistently shown that employees who consider themselves overqualified exhibiting her levels of discontent. For example, over-qualification correlated well with job dissatisfaction in a 2008 study of 156 call-center reps by Israel-ire searchers Saul Fine and Baruch Nevo. And unlike discrimination based on age or gender, declining to hire overqualified workers is perfectly legal.


But even before the economic downturn, a surplus of overqualified candidates was a global problem, particularly in developing economies, where rising education levels are giving workers more skills than are needed to supply the growing service sectors. If managers can get beyond the conventional wisdom, the growing pool of too-good applicants is a great opportunity. Berrin Erdogan and Talya N. Bauer of Portland State University in Oregon found that overqualified workers' feelings of dissatisfaction can be dissipated by giving them autonomy in decision making. At stores where employees didn't feel empowered, over-educated workers expressed greater dissatisfaction than their colleagues did and were more likely to state an intention to quit. But that difference vanished where self-reported autonomy was high.


5. Presidential election

According to the United States Constitution, a presidential election is to be held once every fourth year. The process of electing a President and Vice-President begins long before Election Day. Candidates from both major and minor political parties and independent candidates begin to raise money and campaign at least one year in advance of the general presidential election. In order to officially represent a political party, a candidate must be nominated by that party.


This primary nomination process is a contest that often produces factions within political parties. These divisions impact the policy stances and agendas of the candidates running for nomination as they attempt to garner the support of party leaders and activists. The nominating process officially begins with the first state primaries and caucuses, which usually occur in the month of February of the election year. It is at these local events that voters are given their first chance to participate in electing the nations next President.


There are many factors that influence who will ultimately become the candidate for a party. The public's perception of the candidates is influenced by such things as media reports, public opinion polls,candidate preference surveys, and advertising. These factors will help determine the perceived strengths and weaknesses of the candidates in the months leading up to the caucuses and primaries.


1. Volcano's eruption

Volcanoes blast more than 100 million tons of carbon dioxide into the atmosphere every year but the gas is usually harmless. When a volcano erupts, carbon dioxide spreads out into the atmosphere and isn't concentrated in one spot.But sometimes the gas gets trapped underground under enormous pressure. If it escapes to the surface in a dense cloud, it can push out oxygen-rich air and become deadly.


2.Growth of the internet

The exponential growth of the internet was heralded,in the 1990s, as revolutionizing the production and dissemination of information. Some people saw the internet as a means of democratizing access to knowledge.For people concerned with African development, it seemed to offer the possibility of leapfrogging over the technology gap that separates Africa from advanced industrialized countries.


3.The United Nations

The United Nations is an international organization founded in 1945. Due to its unique international character, and the powers vested in its founding Charter, the organization can take action on a wide range of issues and provide a forum for its 193 Member States to express their views, through the General Assembly, the Security Council, the Economic and Social Council and other bodies and committees. The work of the United Nations reaches every corner of the globe. Although best known for peacekeeping, peace building, conflict prevention, and humanitarian assistance, there are many other ways the United Nations and its system (specialized agencies, funds, and programme) affect our lives and make the world a better place.
