Difference Between Classroom Education And Long Distance ...

What is the distinction between a class room course or the same course by finding out and taking long distance examination online? Are online degree, diploma or certification courses recognized?

Effectively, both have gotten its deserves in addition to its warts.

Traits of classroom courses are:-

When attending classroom educational programs and applications, you should have the peace of mind that you are truly attending a conventional teaching course though it is simply psychological.

You?ll be able to interact and ask questions together with your course instructors and teachers.

You?ll have classmates to discuss points pertaining to your lessons.

The downsides of classroom educational courses are:-

Classroom courses are way more expensive than online courses as a result of to conduct the programs, the institution you might be attending have much higher over prices corresponding to offering its services and employees maintaining them.

There may be additionally traveling time to be considered which is unproductive time loss.

Characteristics of online instructional programs are:-

You may have the consolation of studying and taking exams from home. Definitely very beneficial for busy people like you.

You lower your expenses because on-line instructional programs are a lot less expensive. This in flip can give you a chance to take up a course which you?ll not be able to afford if the course is offered solely on attending classroom lessons.

You will be able to enroll for programs not accessible near where you live. That?s on-line instructional programs are also know as long distance learning.

You have the freedom to resolve when to take on-line examinations since exams might be taken as and when you find yourself ready. However, there is a danger that you may not take the exam as a result of there isn?t any stress to do so.

You save touring time from having to journey to classrooms for lessons.

The downsides of taking online courses are:-

The perception that on-line programs are inferior although many prime academic institutions are providing high-quality on-line courses.

Those online training examinations are of a lower quality. Again this can be another false impression as a result of many high quality institutions providing each on-line and classroom education programs set the identical examination questions for both their classroom and on-line students. Even the markers of the examinations are the academics.

My opinion is that enrolling for online educational courses is far more sensible. Many individuals doubt the effectiveness of the online courses because of the mindset that traditional programs are better. This mindset was created after we were young and attending colleges was the way we have been introduced up. At this time, many educational classes are actually performed on-line due to advance applied sciences which had been then unavailable.

Critics cited that online programs had no lecturers to guide the students. Now, let me ask the critics a question. Since all directions are on the course supplies, why ought to there be a need for somebody to guide you and you pay good money for that? The course examine materials are for you to examine and most of the time you?ll be able to electronic mail your educators ought to you?ve gotten any questions. Due to this fact, the critic?s argument is only for psychological peace of mind.

Nevertheless, you should be prudent in choosing your lengthy distance learning on-line educators. It is because since many people have the perception that lengthy distance on-line education is inferior, then choosing respected educators and institutions will help to dispel such discrimination.

Naturally occurring molecule may prevent atherosclerosis

ScienceDaily (July 11, 2012) ? Cleveland Clinic researchers have discovered that a naturally occurring molecule may play a role in preventing plaque buildup inside arteries, possibly leading to new plaque-fighting drugs and improved screening of patients at risk of developing atherosclerosis.

Sometimes called hardening or clogging of the arteries, atherosclerosis is the buildup of cholesterol, fatty cells, and inflammatory deposits on the inner walls of the arteries, restricting blood flow to the heart. The disease can affect the arteries in the heart, legs, brain, kidneys, and other organs, and is the most common cause heart attacks, strokes, and peripheral vascular disease.

At the cellular level, plaque buildup is the result of macrophages in the vessel wall absorbing, processing, and storing cholesterol (lipids) and then accumulating in large amounts, eventually leading to the development of arterial lesions. The researchers, led by Eugene Podrez, M.D., Ph.D., of the Department of Molecular Cardiology at Cleveland Clinic's Lerner Research Institute, have discovered that the naturally occurring molecule Akt3 regulates lipid entry into macrophages and prevents the cells from storing excessive amounts of cholesterol and collecting in the artery.

Podrez says the discovery could lead to new drugs designed to prevent atherosclerosis. It could also help doctors develop screening tests to determine patient risk level for developing the disease. Podrez and his colleagues are now looking into the particular mechanisms behind Akt3's role in regulating lipid processing and will attempt to replicate their results in humans.

Corals on ocean-side of reef are most susceptible to recent warming

Monday, July 9, 2012

Marine scientists at the University of North Carolina at Chapel Hill have linked the decline in growth of Caribbean forereef corals ? due to recent warming ? to long-term trends in seawater temperature experienced by these corals located on the ocean-side of the reef. The research was conducted on the Mesoamerican Barrier Reef System in southern Belize.

The results were revealed online in the July 8 issue of Nature Climate Change, a journal that publishes research on the impacts of global climate change and its implications for the economy, policy and the world at large.

The Mesoamerican Barrier Reef System is the second largest reef ecosystem in the world and the largest in the Western Hemisphere, stretching along the coasts of Mexico, Belize, Guatemala and Honduras. In February 2009, UNC researchers Karl Castillo and Justin Ries used a large pneumatic drill to extract 13 core samples from massive starlet corals on the reef and measured the thickness of their annual growth bands in order to estimate trends in their growth rates over the last 100 years. They found a decline in skeletal growth in corals closest to the open ocean, while growth in corals from the other two reef zones ? the nearshore (located closest to the shore) and the backreef (located directly behind the reef crest) ? remained relatively unchanged.

Castillo, a postdoctoral researcher in the marine sciences department in the College of Arts and Sciences who is a native of Belize, said they surmised that this decline in skeletal growth in the forereef zone was due to a recent rise in seawater temperature, but they wanted to test their hypothesis in this latest study.

They gathered sea surface temperatures for the study site from 1982 to 2008 from the National Oceanic and Atmospheric Association's (NOAA) high-resolution seawater temperature database, which were derived from satellite measurements. They compared that dataset with seawater temperatures extracted from temperature loggers Castillo had installed at the study site in 2002.

Historically, corals in the area closest to the open ocean have seen cooler and more stable seawater temperatures, while those located closest to the shore and behind the reef crest have experienced warmer and more variable seawater temperatures.

Since 1982, the average summer sea surface temperature has been increasing in all three reef zones. Castillo said they found that with an increase in sea surface temperatures, skeletal growth declined over the 1982-2008 interval in the zone closest to the open ocean, while coral growth rates remained relatively stable over that same period in the other two reef zones.

"It looks like forereef corals are the first of this species to be affected on this reef system, suggesting that they may be most vulnerable to recent and future global warming," Castillo said. "However, because backreef and nearshore coral colonies have historically been exposed to warmer and more variable seawater temperatures, they seem to be less affected."

The findings of this new research study offer insights into how corals are likely to respond to future warming. They also highlight the importance of understanding cross-reef differences in the corals' tolerance for rising sea temperatures in an era of rapid global climate change. By identifying which corals are most vulnerable to warming, this work may help coral reef managers triage the reef ecosystem that they are trying to protect, the scientists said.

The researchers, accompanied by graduate and undergraduate students, headed back to Belize this summer to collect additional coral core samples that span the entire reef system, a length of approximately 200 miles, Ries said. Their previous study covered less than one-fifth of that region.

Amelia Earhart expedition searches coral atoll for wreckage

AP file

This undated file photo shows Amelia Earhart. A new expedition is attempting to find the wreckage of the plane she flew in her attempt to circumnavigate the globe in 1937.

By James Eng, msnbc.com

Seventy-five years after Amelia Earhart went missing over the Pacific Ocean while attempting to circumnavigate the globe, a new expedition will search the waters in hopes of resolving the longstanding mystery of what happened to the American aviation pioneer.

The Niku VII expedition will search the underwater reef slope off the west end of Nikumaroro, formerly Gardner Island, an uninhabited coral atoll in the Pacific, looking for signs of wreckage from Earhart?s Lockheed Electra.

The expedition is being led by Richard Gillespie, executive director of The International Group for Historic Aircraft Recovery, or TIGHAR (pronounced ?tiger?),? a Wilmington, Del.-based nonprofit group that promotes aviation archaeology and historic preservation.

---

?The primary search area is based upon the hypothesis that the aircraft landed safely on the reef and remained there for several days before being washed over the reef edge by rising tides and surf,? TIGHAR says on its website in explaining the mission. ?Aircraft debris reportedly found and used by island residents in later years, and aircraft parts found by TIGHAR in the abandoned village strongly suggest that the aircraft broke up in the relatively shallow surf zone.?

Earhart became the first woman to fly solo across the Atlantic Ocean in May 1932, when she took off from Harbour Grace, Newfoundland, and landed the next day in Londonderry, Northern Ireland.

In March 1937, she attempted to fly around the world in a twin-engine Lockheed Electra, but a tire blew out during takeoff from Hawaii and she crashed.

After her plane was repaired, Earhart, then 39, set out on a second attempt from Miami in June 1937 with navigator Fred Noonan. They were on the last leg of the flight when the plane went down on July 2, 1937, while approaching Howland Island, a remote coral island in the central Pacific Ocean about 1,700 nautical miles southwest of Honolulu.

U.S. Coast Guard and Navy ships searched the area but turned up no sign of the crew or the plane. Earhart?s disappearance remains a mystery to this day.

Many researchers believe Earhart?s plane ran out of fuel and the pair ditched at sea. But other theories abound, with some conspiracy theorists suggesting Earhart was caught and held by the Japanese as a spy.

The expedition led by TIGHAR assumes that the pair reached Gardner Island, then a British possession, and survived for an unknown period of time.

Crews using underwater robots will search the waters with high-frequency sonar and take black-and-white photos down to a depth of nearly 5,000 feet (1,500 meters), according to TIGHAR. The expedition will be able to examine sonar targets using high-definition video down to a depth of 3,300 feet (1,000 meters).

The object of the expedition is to locate, identify and photograph any wreckage found. There are no plans to recover any wreckage.

"What we're hoping for is to come back with good imagery, photographs, of wreckage that's conclusively, unquestionably pieces, at least, of Amelia Earhart's Lockheed Electra aircraft; that's the goal," Gillespie told the BBC.

A documentary on the expedition will be broadcast on the Discovery cable television channel.

Parent: Students watched porn in classroom

SAN DIEGO -- The parent of a middle school child is calling for action in the wake of an alleged incident that happened in a seventh-grade classroom.

The San Diego Unified District confirms nine male students from Bell Middle School were suspended in May, but legally could not say why the students were suspended.

Now, a parent is telling NBC 7 San Diego the students were allegedly watching pornography on their cell phones during English class and masturbating.

---

See the original report at NBCSanDiego.com

The teacher in the classroom at the time, Ed Johnson, allegedly did nothing to stop the incident, only saying he would give students referrals if he caught them. Sources said Johnson then continued reading to students while at his desk.

The parent, Edith Duran, said she had a meeting with the vice principal who told her about the sexual activity.

Duran says her son was not involved in the incident, but was in the classroom at the time, afraid to speak up for fear of being bullied.

?When I send my child to school I want to feel he's safe. I don't send him to sit in a classroom next to boys watching porn, explicit porn which [the] vice principal did tell me [was] very explicit,? she said.

?I asked the vice principal how is it this was going on under his nose, a group of boys huddling around a cell phone watching porn; how is it this was going on and he had no idea??
According to Duran, the vice principal had no answer for that question, but said this about the teacher's reaction.

?She said he is in shock. Mr. Johnson is in shock, he can't believe this happened. That's what she said,? said Duran. ?Let this be a reality check that he needs to do a better job as far as teaching our children and not just sitting back reading and letting them do whatever it is they want to do.?

In the end, Duran believes her son and other students in that class are victims.

?I do expect a phone call. I want therapy, I want some kind of counseling, not just for my son, but for other children victimized in this situation,? Duran told NBC 7 San Diego.

Duran said the school did initially promise therapy and counseling for the students in the classroom, but she has heard nothing from the administration, despite her attempts to follow-up.

She wants more Bell Middle School parents to reach out to her and join her in demanding something be done for the students in the class who she said were victimized by this inappropriate behavior.

The school district would not comment on whether that teacher is currently under investigation, but sources told NBC 7 San Diego a substitute teacher was placed in the classroom with the teacher following the incident until the end of the school year.

NBC 7 has been unable to reach the teacher for comment.

Ranchers, farmers seeking solutions to U.S. water worries

BLOOMING GROVE, Texas (Reuters) - Texas cattle rancher Gary Price knows what it is like to worry about water.

With 2,500 acres of rough range land situated about an hour south of Dallas, Price relies on rain-fed soils to provide the hearty grass forage he needs to fatten his cattle. When the animals are sold at grocery meat counters, every pound of flesh spells potential profit for Price's family.

"Ranching is really mostly about water and grass. So you've got to look at ways to control water," Price said in an interview at his 77 Ranch, where temperatures over 100 degrees drive his cattle into the shade every day and have spurred swarms of hungry grasshoppers.

A recent stretch of devastating drought in Texas and fears of ongoing water scarcity across many parts of the United States are pushing Price and others in ranching and farming into new frontiers of water conservation.

In Price's case, that means teaming up with a corporate partner, water-thirsty MillerCoors Brewing Co. The second-largest U.S. brewer has been helping him build fences for new grazing rotations and plant native prairie grasses that grow thick, retain rainwater and limit runoff.

Corporate America's concerns about water availability are not new, but of late they are growing. More than 40 international corporate leaders met in June in Rio De Janeiro to reaffirm the need for concerted action to address a growing water crisis.

Across the globe, water consumption has tripled in the last 50 years, and at least 36 U.S. states are anticipating some areas of water shortages by 2013, according to the Environmental Protection Agency. Farming alone consumes 70 percent of all fresh water used around the world.

With that in mind, public and private interests working on water conservation have started pushing partnerships with farmers and ranchers to protect water quantity and quality. The work is starting in Texas but is intended to spread nationwide.

INVEST IN FARMING PRACTICES

In May, the U.S. Department of Agriculture said it would fund $2.8 million for improved land and water management practices like those on Price's land, providing incentives to farmers in an area of Texas that targets 152,309 acres.

"It is not going to be one organization or one company or one government that is going to solve this problem. It is going to take all of us collectively," said Kim Marotta, MillerCoors director of sustainability.

MillerCoors acted after an internal assessment showed that three of its eight U.S. breweries, including one in Fort Worth, Texas, faced potential water shortages. The company is working on water conservation at its breweries, but also is identifying large agricultural water users near its breweries and asking to partner with them on conservation.

"We're just starting that work," Marotta said. "You have to start farm-by-farm."

The moves come as water gains stature as an critical asset, a must-have resource that everyone from farmers to investment fund managers need to control. At MillerCoors, for example, it takes about 4 gallons of water to make 1 gallon of beer.

The Texas efforts follow the 2011 drought that cost state agriculture more than $7 billion in losses. Last year was the driest year in state history. While some parts of Texas have since received rain, the drought appears to be spreading to the U.S. Midwest and to parts of the southern Plains again as scorching heat and cloudless skies burn up crops and pasture.

"You have to do more with less," said Ken Klaveness, executive director of Trinity Waters, a non-profit conservation group focused on the 512-mile-long Trinity River, which supports water needs for over 40 percent of Texans.

"If you want your business to be here 15 to 20 years from now, you need to be proactive," Klaveness said.

Projects with farmers can range from planting of grasses with deeper root systems that hold water and reduce erosion to installing high-tech monitoring stations in pastures.

FARMERS, RANCHERS CHANGING TECHNIQUES

Farmers are being asked to change irrigation techniques and equipment and plant a mix of different crops. Ranchers are asked to alter the ways they rotate their cattle grazing.

MillerCoors is also working with 800 barley farmers in Idaho to alter their irrigation practices in ways that use less water. MillerCoors will not disclose how much it is spending, but Marotta said the effort was a high priority.

The company has worked with Trinity Waters and groups like the Sand County Foundation, a Wisconsin-based non-profit that works with landholders to improve natural habitats.

Though he has long worked on ways to preserve water on his ranch, Price says creating a 40-acre wetland and planting more native grasses in recent years with the outside funding has helped make him better prepared for the Texas droughts.

Three of Price's pastures now sport large metal contraptions containing computers that monitor rainfall and runoff through varying types of grass. Though results are not yet in, the hope is that scientists monitoring the results will be able to determine which grasses are most effective and approximately how much water they help prevent from running off.

Price also has new fencing and a showcase variety of the water-trapping native prairie grasses. The grasses grow so thick and lush even with scarce rainfall that his pastures have a marked distinction from those of his nearby neighbors who have cultivated more typical bermuda grasses.

By preventing erosion and runoff when it does rain, and holding more moisture in the soil, Price is improving his ability to feed his cattle without costly supplemental hay. He is also reducing sediment contamination of nearby streams.

Klaveness said many other landowners are moving to make similar improvements on their lands, including more than 100 who have applied for government grants for the work.

"We have over 200,000 acres of landowner interest we are getting ready to mobilize," he said. "The water we have is finite. We can't make more."
