Alaska’s Pavlof volcanic eruption grows more violent: air traffic disrupted by rising ash cloud

The Extinction Protocol's avatarThe Extinction Protocol

May 21, 2013 –ANCHORAGE, Alaska – One of Alaska’s most active volcanoes, which has been belching ash and spewing lava since last week, has forced regional flight cancellations and dusted some nearby communities with ash, scientists and local officials said on Monday. Pavlof Volcano has sent up ash as high as 22,000 feet, with the cloud blowing eastward and the eruption showing no signs of abating, according to the federal-state Alaska Volcano Observatory. The lava from its 8,261-foot (2,518-metre) peak has also created huge steam clouds on meeting the mountain’s snow. While the ash plume was still too low on Monday to affect commercial airliners flying at least 30,000 feet above sea level between Asia and North America, it was scrambling schedules for regional carriers serving rural fishing towns and native villages that lack outside road access. PenAir, an Anchorage-based Alaska company specializing in travel in southwestern Alaska, briefly…

Sujni: Traditional Embroidary From Bihar

Ranjit Singh's avatarFree Thoughts by Ranjit Singh

Sujuni, is a traditional craft of Bihar. It is made by women and depicts the animal, bird and day to day activities of village life. It is technically done by straight running stitch embroidery on layered cotton.Women quilt together old sari and other pieces of cloth with tiny running stitches,and embroider these beautifully. The product is a quilt-cum-bedspread,sometimes stuffed with tattered cloth to give it added thickness. Sujuni is labour intensive-the number of stitches per square inch varies from 105-210. A fine running stitch all over the sheet in the same colour as the base cloth creates the background upon which motifs are outlined in chain stitch. The design is then filled in with tiny rumming stitches in coloured thread. An age-old practice among women in almost all parts of the country, what makes sujuni remarkable is the unique narrative elements in its embroidery. Women stitch their experience, their…

The disposable academic Labour(link)

 Martin Luther once nailed 95 theses to the door of a church . A thesis was simply a position one wanted to argue. Luther, in his theses asserted that Christians could not buy their way to heaven. Today a doctoral thesis is both an idea and an account of a period of original research. Writing one is the aim of the hundreds of thousands of students who embark on a doctorate of philosophy (PhD) every year.

In most countries a PhD is a basic requirement for a career in academics.

Rich History!!

For most of history even a first degree at a university was the privilege of a rich few, and many academic staff did not hold doctorates. But as higher education expanded after the second world war, so did the expectation that lecturers would hold advanced degrees. American universities geared up first: by 1970 America was producing just under a third of the world’s university students and half of its science and technology PhDs (at that time it had only 6% of the global population). Since then America’s annual output of PhDs has doubled, to 64,000.Other countries are catching up fast though.

Universities soon discovered that PhD students are cheap, highly motivated and disposable labour. With more PhD students they can do more research, and in some countries more teaching, with less money.

In research the story is not different. PhD students and contract staff known as “postdocs”, described by one student as “the ugly underbelly of academia”, do much of the research these days. There is a glut of postdocs too.

Fashion Change can Destroy Careers

These armies of low-paid PhD researchers and postdocs boost universities’, and therefore countries’, research capacity. Yet that is not always a good thing. Brilliant, well-trained minds can go to waste when fashions change.!!

Highest-resolution Global Forest Cover Dataset

A team of Researchers at the University of Maryland have developed a 30-meter resolution forest cover data set that could boost our  efforts to track deforestation and forest degradation.

The dataset, which is published in the International Journal of Digital Earth, is based on combining data from two satellite sensor systems: 250-meter resolution MOderate-resolution Imaging Spectrometer (MODIS) and 30-meter Landsat imagery. The merger results is a tree cover layer that is more accurate than the industry standard for global forest measurement: the MODIS-based Vegetation Continuous Fields (VCF) dataset.

The development is more important because land-use changes like deforestation, forest degradation, and reforestation often occur at scales too small to detect with conventional VCF-based systems, according to the study’s lead author Joseph Sexton.

The development may  prove a “game changer” for tracking changes in forest cover.
