Brazil's ethanol revolution

"United Nations, June 2008 - The bio-fuel, ethanol, is generating a revolution in renewable energy that could help reduce the world's thirst for oil. In Brazil, the production of ethanol from sugarcane is booming, but what is not clear is the impact it is having on the industry's sugarcane cutters."  Transcript of video available here.

Nicole Kearsch's curator insight, October 7, 10:29 AM

The idea of Brazil using sugarcane to partly fuel cars could be a brilliant idea.  However the effects that is has may not be.  With this concept the idea of the sugarcane cutters would be no longer in existence.  This puts droves of people out of work.  Officials say that they will absorb these cutters into other jobs, but will that really be a way to give everyone a job?  Environmentally, however, the idea is good as they will no longer be setting controlled fires to help the cutters harvest the sugarcane.

Samuel D'Amore's curator insight, October 8, 12:39 PM

In a time where alternative energy sources are sorely needed Brazil's sugar cane ethonal is very interesting. While it mIgbo not be the answer to our problems it is at least the sign that nations can be willing to throw support and funding into alternative energy. Another aspect of it is how will this affect the Native Brazilians, especially those in the sugar cane industry. Will they loss their livelihood to more efficient machines or will the ethonal simply increase in value untill the locals can no longer afford it.

Hector Alonzo's curator insight, October 30, 7:38 PM

Brazil's ethanol revolution is showing how the country is using its agriculture to help out its economy, but with the increase in cane production comes the laying off of all the manual cutters. Essentially, the countries success in ethanol production is resulting in job loss for the workers that made the production of ethanol as popular as it.

It's amazing to see that even though we have been on this planet for so long, there are stilll mysteries such as this. Tjis could have taken year s to solve but looking at the picture in the slides at the bottom of the article, it seems like this group of scientists knew exactly how to figure this out. this all happens becasue of geography and where these rocks are in the world that make them move around. Iis in a dried up lake pond that freezes over at night to create a layer of ice strong enough to help the rocks move around at night. This discovery took 2 whole years to figure out, but was vey much worth it in the end.

Albert Jordan's curator insight, February 12, 5:22 PM

Brazil being in the top 15 of countries with the largest defense budget is not all that surprising considering the political, social, and economic situations of South America. Within Brazil’s sphere of influence, especially areas west of its developed cities, the Amazon jungle still is used by those deemed enemies of the state, whether actual or politically based. Because of that, there comes the difficult task of tracking and deterring rebel activity, arms or drug smuggling, etc. The borders that Brazil share with Bolivia, Colombia, and Venezuela; border security is  likely to be a concern due to the history of drug manufacture and shipping from those nations, along with the violence and corruption that comes with that activity. Not to mention the historical and violent political instability these countries have faced, which are still a concern for the region and world. Venezuela, being an “enemy of the U.S.” and Brazil being an ally, this border area is probably highly militarized or monitored. With this in mind, a slight musing could be given towards how much of the military aid and counter narcotics aid from the United States goes into Brazil’s military funding.

Brazil is also the one of the most stable and economically strong countries on the continent and in order to continue that, the government must be able to keep instability coming over from the border in check as well as deal with rebel forces using the Amazon as a safe haven. What is surprising to me however is that with how far away the rest of the countries in South America are from Brazil in military expenditures causes me to pause and think about just what they may be worrying about from their neighbors? Perhaps as they attempt to get a seat at the big table in international affairs, they feel having a stronger military will improve their image. They may not be worried about regional infighting due to the difficult terrain of the area which would make any military campaign extremely difficult and costly, besides a host of other reasons. In conclusion, Brazil is more than likely looking towards international interests in addition to showcasing their swelling national pride by spending $175 U.S. dollars per person on military expenditures while many continue to go hungry living in the famous favelas of Cidade de Deus.

Jessica Rieman's curator insight, February 18, 1:32 PM

Russia is the third highest goverment military that spends around 143 million people lived in Russia in 2012 and they spent around $475 per person on it's military. Russia compared to China and the US is another story the US is number one in who spent the most on their military forces at $600.4 billion. As far as China is concerened it comes in at number two at spending around  $112.2 billion. These numbers make sense especially for the power house that China is and how their values of militarism affect their spending and their way of society/life.

Burning Man

This annual arts festival with a strong counter-cultural ethos literally is an experiment in producing alternative urban and cultural geographies.  They reject many normative regulations embedded within mainstream society.  These geographies created last only about a week, as an escape from the regular strictures of society.  The ephemeral alternative geographies then fade back into the desert but not without creating a visually remarkable place that has a lasting impact for participants.  A word of caution, it is a 'clothing-optional' event, so launching a Google image search live in class is not recommended.

 

I'll let the producer of the video explain: "It is an 8-day event which takes place annually in late August in the temporary city of Black Rock City located in a dry lakebed in northwestern Nevada, USA.  The radial streets are laid out like a clock face, from 2:00 to 10:00. I have marked some of these streets as well as some of the prominent and favorite theme camps and villages.  The attendees are all participants in a sense and are themselves the attraction. There is no corporate sponsorship or presence of any sort. Only ice and coffee are sold (and proceeds benefit community projects). Everything else is brought in under the concept of 'radical self-reliance' or gifted by others. Most 'burners' participate by finding the creative or artistic thing that they enjoy most and do best, do it to the fullest extent, and share it as much as possible."

Why Technology Is Key to Overcoming the Language Barrier

Why Technology Is Key to Overcoming the Language Barrier | social geography | Scoop.it

Language barriers prevent us for completely connecting. But what if the language barrier didn't exist?

 

DB: Presently we are living in a rapidly changing world where the spread of ideas and items are occurring at a rate unprecedented in history. In this globalized and increasingly interconnected world, the variation of languages spoken is drastically decreasing. As some of the most genuine characteristics of a culture are intertwined within its langue, a reduction in spoken languages and increased interaction is threating the duration of some traditional ways of living. Likewise since economics is one of the thriving factors behind globalization, the ability to communicate with your market has become paramount. However technological innovation is currently in the process of making up for the shortage of qualified linguists around the globe. Although possessing a universal portable translation device is currently beyond our capacity, it is likely that such a device similar to what was once believed possible only in science fiction may be readily available within our lifetime. Whether it becomes a public utility or a commensal asset as well as who has access to it remains to be decided. Yet this also brings up an important question of how culture will be affected if the language barrier is overcome through technology? Can geographic cultural diffusion continue to function if everyone can easily understand each other? What happens when worlds lose their cultural significance for the sake of convenience?

A new technology based around the concept of translation that aims to overcome the language barrier. Although the author states that even if they sitting in the same room as a colleague and are both native English speakers, they may still only understand 98% of their intended meaning. So for that reason alone, translation technology will never be perfect, but they believe this is a step in the right direction.

World’s Largest Dam Removal Unleashes U.S. River After Century of Electric Production

World’s Largest Dam Removal Unleashes U.S. River After Century of Electric Production | social geography | Scoop.it
The last section of dam is being blasted from the Elwha River on Washington's Olympic Peninsula on Tuesday.

 

For almost half a century, the two dams were widely applauded for powering the growth of the peninsula and its primary industry. But the dams blocked salmon migration up the Elwha, devastating its fish and shellfish—and the livelihood of the Lower Elwha Klallam tribe. As the tribe slowly gained political power—it won federal recognition in 1968—it and other tribes began to protest the loss of the fishing rights promised to them by federal treaty in the mid-1800s. In 1979, the U.S. Supreme Court ruled that Washington tribes, including the Elwha Klallam, were entitled to half the salmon catch in the state.

Read of the day: Social evolution: The ritual animal | social geography | Scoop.it
Praying, fighting, dancing, chanting — human rituals could illuminate the growth of community and the origins of civilization.

-

"..

As an example of how rituals can cause values and preferences to become sacralized, Atran points to his studies showing that, in the United States, people who attend church more frequently are more likely to consider the right to bear arms a sacred value11.

“Emotionally intense rituals have bound us together and pitted us against our enemies throughout the history of our species,” says Whitehouse. “It was only when nomadic foragers began to settle down did we discover the possibilities for establishing much larger societies based on frequently repeated creeds and rituals.”

The big question, he says, is whether this kind of unity can be extended to humanity at large. For Whitehouse, understanding the ways that rituals shape group behaviour is the first step towards finding out how they can be harnessed to dampen down conflict between groups. He hopes that such insights could help policy-makers to “establish new forms of peaceful cooperation, as well as bringing down dictators”.

MIT discovers a new state of matter, a new kind of magnetism

MIT discovers a new state of matter, a new kind of magnetism | social geography | Scoop.it
Researchers at MIT have discovered a new state of matter with a new kind of magnetism. This new state, called a quantum spin liquid (QSL), could lead to significant advances in data storage.

 

Researchers at MIT have discovered a new state of matter with a new kind of magnetism. This new state, called a quantum spin liquid (QSL), could lead to significant advances in data storage. QSLs also exhibit a quantum phenomenon called long-range entanglement, which could lead to new types of communications systems, and more.

 

Generally, when we talk about magnetism’s role in the realm of technology, there are just two types: Ferromagnetism and antiferromagnetism. Ferromagnetism has been known about for centuries, and is the underlying force behind your compass’s spinning needle or the permanent bar magnets you played with at school. In ferromagnets, the spin (i.e. charge) of every electron is aligned in the same direction, causing two distinct poles. In antiferromagnets, neighboring electrons point in the opposite direction, causing the object to have zero net magnetism (pictured below). In combination with ferromagnets, antiferromagnets are used to create spin valves: the magnetic sensors used in hard drive heads.

 

In the case of quantum spin liquids, the material is a solid crystal — but the internal magnetic state is constantly in flux. The magnetic orientations of the electrons (their magnetic moment) fluctuate as they interact with other nearby electrons. “But there is a strong interaction between them, and due to quantum effects, they don’t lock in place,” says Young Lee, senior author of the research. It is these strong interactions that apparently allow for long-range quantum entanglement.

Texas has the highest immigrant income out of all of the states. Also Texas has very few naturalized citizens who used to be an immigrant.

This map relates to unit 2 because it shows the illegal immigration. And immigration theories. This proves ravensteins laws correct because it shows how people move a short distance to migrate, knowing that most migrants to America come from Latin America.

Visualizing Regional Population Statistics

It was just over two centuries ago that the global population was 1 billion — in 1804. But better medicine and improved agriculture resulted in higher life expectancy for children, dramatically increasing the world population, especially in the West.

 

This is an excellent video for population and demographic units, but also for showing regional and spatial patterns within the global dataset (since terms like 'overpopulation' and 'carrying capacity' inherently have different meanings in distinct place and when analyzed at various scales). It is also a fantastic way to visualize population data and explain the ideas that are foundational for the Demographic Transition Model.
