A degree with a difference: using South African sign language instead of the written word

This Masters degree sets a precedent in South Africa and gives universities that want to be truly inclusive a lot to think about.

Nyeleti Nokwazi Nkwinika was a year into her Master’s dissertation in English, and she was struggling. This has nothing to do with her work ethic: the problem lay with her hearing. Nyeleti was born deaf and like many others in her situation, she battles with written language.

Most deaf people are born into hearing families who don’t have any skills in Sign Language. In Nyeleti’s case, she only learned to use South African Sign Language fluently at school. When she got to high school she attended a mainstream hearing school with several other top performing deaf pupils from her previous school.

By then, she had missed out on too many years of access to English. South African Sign Language and English are differently structured. This can make it hard to learn for deaf people who’ve only ever used sign language to communicate. It’s also very difficult to learn written English when one has never heard the language or used it for conversational purposes.

Southeast Asia before ASEAN: An ASEAN 50 Commemorative Post

Ironically, the region of Southeast Asia was not an Asian concept. It was a Western one. It was perceived primarily through Western eyes as maps were created during the colonial rush to Asia from the 16th to the early 20th century. Hence, it originated as a geographical concept, having been rendered in different words by Western scholarship, especially before the Second World War– words such as “south east Asia”, “southeast Asia” or “south-east Asia.” In the 1930s for example, Southeast Asia was referred to as “Further India” (as if to allude that it’s near the Bay of Bengal, when it is not) or “Asia of the Monsoons” (to refer to the typhoons that frequently ravage the area.” The regional name’s gradual standardization (no longer in the lowercase “southeast”) and the dropping of the hyphen resulted in the name “Southeast Asia.” It was first used and asserted by the Americans, with its U.S. State Department’s “division of Southeast Asian Affairs” and came to be used frequently by the media as the Second World War sparked in the Pacific in 1941.

After the war, the term “Southeast Asia” transformed from a geographic entity to be referred to, to a complex and inchoate group of nations trying to redefine themselves in the world. As each one dropped their colonial fetters and became independent–Indonesia from the Dutch (17 August 1945), Vietnam from the British (2 September 1945), the Philippines from the United States (4 July 1946), Myanmar from the British (4 January 1948), Laos (22 October 1953) and Cambodia (9 November 1953) from the French, Singapore and Malaysia from the British (16 September 1956), Brunei from the British (1 January 1984), with Thailand successfully retaining its sovereignty, each one has tried to redefine their identities apart from their colonial past. With ideological conflicts in parts of Asia, a Southeast Asian integration seems far off. 

*Front page of the Southeast Asia Collective Defense Treaty, 8 September 1954, from the Archives New Zealand. The first attempt at a Southeast Asian cooperation was done in 1954. The United States initiated an alliance that was meant to contain Communism in Asia, and hence, on 8 September 1954, the Southeast Asia Collective Defense Treaty (or the Manila Pact) was signed by only two Southeast Asian countries–the Philippines and Thailand–and joined by the United States, France, Great Britain, New Zealand, Australia, Thailand, and Pakistan. This established the Southeast Asian Treaty Organization or SEATO, where all member countries agree that if any one of them were attacked, all the other member countries would come to its defense–very similar to the North Atlantic Treaty Organization (NATO). But SEATO would end as a failure, for the simple reason that it was seen suspiciously by the rest of Southeast Asia as “a fig leaf for the nakedness of American policy.” Pakistan withdrew in 1972, and France in 1975.

*Philippine President Macapagal, Indonesian President Sukarno and Malaysian Prime Minister Tunku Abdul Rahman signing agreements forming the MaPhiLindo on 5 August 1963 at the Juan Luna Hall of the Department of Foreign Affairs in Manila, from the Malacañang Presidential Museum and Library.

*The Philippine Commonwealth Government-in-Exile proposed a union with Indonesia in 1943, a Pan-Malayan principle reflected in this part of an American 1942 map entitled “Outline of the Post-War New World Map,” a proposed political boundary map at the event that the Allied forces would win World War II. The one marked in blue are the proposed American protectorates of the post-war world.

At almost the same time, another effort was put in at the time of President Diosdado Macapagal. Coming from our commonality as Malays (with the vision of the late President Manuel L. Quezon for a Pan-Malayan nationhood), President Macapagal envisioned a cooperation with other Malay countries. Hence, Macapagal convened a summit in Manila, together with Malaysian Prime Minister Tunku Abdul Rahman and Indonesian President Sukarno, where they signed the Manila Accord on 5 August 1963, addressing controversial issues over North Borneo and Sarawak joining the Federation of Malaysia. The Accord established the Maphilindo, striving for “Asian solutions by Asian nations for Asian problems.” However, this was also seen as a move by the Philippines and Indonesia to stall or halt the formation of the Federation of Malaysia, which eventually happened on 16 September 1963. Indonesia pulled out of the organization, in reaction to Malaysia’s formation which was seen by Indonesia as a threat to its sovereignty, hence the org’s dissolution.

*The five “Founding Fathers” of the ASEAN, signing the Bangkok Declaration, also known as the ASEAN Declaration, on 8 August 1967. From the ASEAN Archive.

This explains the tensed environment that the five Foreign Ministers of Southeast Asia found themselves in on 8 August 1967 in the Thai Department of Foreign Affairs in Bangkok, Thailand. Carefully, and diplomatically, these representatives from Indonesia (Adam Malik), Malaysia (Tun Abdul Razak), Singapore (S. Rajaratnam), Philippines (Narciso Ramos) and Thailand (Thanat Khoman), sat down together, chose their words carefully, patiently wrestled on their issues through dialogue, and bravely met on common ground. It entailed a larger vision, one that did not only concern each of their nation’s concerns, but one that gave space to regional unity in spite of their differences. Rajaratnam said to his counterparts on that day:

We must think not only of our national interests but posit them against regional interests: that is a new way of thinking about our problems. And these are two different things and sometimes they can conflict. Secondly, we must also accept the fact, if we are really serious about it, that regional existence means painful adjustments to those practices and thinking in our respective countries. We must make these painful and difficult adjustments. If we are not going to do that, then regionalism remains a utopia.

“Painful adjustments” indeed. After all was said and done, the five Foreign Ministers, representing their heads of state, after months of negotiations and compromise, finally and unequivocally signed the two-page ASEAN Declaration, establishing the Association of Southeast Asian Nations, and committing themselves to resolving disputes by peaceful means and through hard but committed mutual accommodation. Bereft of the colonial baggages of the previous southeast asian intergovernmental organizations, it was Southeast Asian, from the inception of the idea to its founding. 

The founding of the ASEAN in 1967 led to the diplomatic reconciliation between Malaysia and Indonesia, and Malaysia and Singapore. And while a year later, Malaysia temporarily severed its diplomatic relations with the Philippines due to claims over Sabah, this kind of issues never impeded the commitment the two nations have in ASEAN, so was with the other member-states with similar problems. Since then, ASEAN has grown into a 10-member-state organization. This probably explains why ASEAN is “the most successful inter-governmental organization in the developing world today.”

In the occasion of the Philippine Chairmanship of the ASEAN and its 50th founding anniversary, Happy ASEAN 50th!

*Post-script: The deafening silence of the Philippines with its unprecedented win in the arbitration ruling in the ASEAN meetings ought to make people question our foreign policy. Insisting on our sovereign rights over our EEZ does not mean war-mongering. Vietnam, on the other hand, the nation that defeated the United States in the Vietnam War, still insists the rule of law thus challenging Chinese encroachment diplomatically. It exemplifies a fair and “independent foreign policy.” The Philippines should follow Vietnam’s example.

Ottoman Empire and Edo-era Japan. You probably never thought about them together before, right? Turns out the Ottomans knew about Japan since at least the late 1600s, because the Ottoman scholar Katip Çelebi included Japan in his atlas “Displaying the World.”

He didn’t quite get the shape of the islands, or their number, or their names…but hey, he tried!

Where does the word ‘meme’ come from?

The word meme was originally coined in the 1970s by sociobiologist, Richard Dawkins, from the ancient Greek for imitation. 

He used it to describe how ideas and symbols propagate through a culture like genes through a population. 

With the advent of the Internet, the process became directly observable in how jokes and images were popularized at lightning speed and soon the word came to refer to a certain kind of image.

So ‘meme’ not only describes how words become part of language, the word is a meme itself. As it turns out, there’s a word for words that describe themselves: ‘autological’.

Spread the word! ;)

Science Fact Friday: Tetrodotoxin, ft. a small gif because I’m avoiding my real obligations. Why does tetrodotoxin not affect its host? More studies need to be done but at least a few species possess mutated sodium ion channels. The tetrodotoxin can’t interact efficiently with the altered channels.

Another interesting tidbit: Animals with tetrodotoxin can lose their toxicity in captivity. It is suspected that the animals accumulate the toxic bacteria as a side-effect of their diet. After several years of captivity on a tetrodotoxin-bacteria-free diet, the bacterial colonies living in the animals die, residual toxin is cleared from the system, and the animal is safe to handle.

Curves of constant width

                                                    Source

The width of a circle is constant: its diameter.

But the circle is not the only shape that holds this pristine title. For instance let’s look at the Reuleaux triangle

Reuleaux triangle

A Reuleaux triangle is a shape formed from the intersection of three circular disks, each having its center on the boundary of the other two.

The Reuleaux triangle is the first of a sequence of Reuleaux polygons, curves of constant width formed from regular polygons with an odd number of sides.

Some of these curves have been used as the shapes of coins

To drill square holes.

They are not entirely square, their edges are fillets i.e the edges are rounded and not sharp.

This animation offers a good insight as to why that is so.

And in china, apparently on bicycles.

The man Guan Baihua shows his self-made multi-angle-wheel bicycle on May 6, 2009 in Qingdao of Shandong Province, China. Guan Baihua spent 18 months to complete this strange bicycle.

Other shapes of constant width

There are other shapes of constant width beside the Reuleaux triangle ( that has been discussed in this post ), a whole bunch of them really. Do take a look at them. ( links below )

I will leave you guys with my favorite one.

Complex learning dismantles barriers in the brain

Biology lessons teach us that the brain is divided into separate areas, each of which processes a specific sense. But findings published in eLife show we can supercharge it to be more flexible.

Scientists at the Jagiellonian University in Poland taught Braille to sighted individuals and found that learning such a complex tactile task activates the visual cortex, when you’d only expect it to activate the tactile one.

“The textbooks tell us that the visual cortex processes visual tasks while the tactile cortex, called the somatosensory cortex, processes tasks related to touch,” says lead author Marcin Szwed from Jagiellonian University.

“Our findings tear up that view, showing we can establish new connections if we undertake a complex enough task and are given long enough to learn it.”

The findings could have implications for our power to bend different sections of the brain to our will by learning other demanding skills, such as playing a musical instrument or learning to drive. The flexibility occurs because the brain overcomes the normal division of labour and establishes new connections to boost its power.

It was already known that the brain can reorganize after a massive injury or as a result of massive sensory deprivation such as blindness. The visual cortex of the blind, deprived of its input, adapts for other tasks such as speech, memory, and reading Braille by touch. There has been speculation that this might also be possible in the normal, adult brain, but there has been no conclusive evidence.

“For the first time we’re able to show that large-scale reorganization is a viable mechanism that the sighted, adult brain is able to recruit when it is sufficiently challenged,” says Szwed.

Over nine months, 29 volunteers were taught to read Braille while blindfolded. They achieved reading speeds of between 0 and 17 words per minute. Before and after the course, they took part in a functional Magnetic Resonance Imaging (fMRI) experiment to test the impact of their learning on regions of the brain. This revealed that following the course, areas of the visual cortex, particularly the Visual Word Form Area, were activated and that connections with the tactile cortex were established.

In an additional experiment using transcranial magnetic stimulation, scientists applied magnetic field from a coil to selectively suppress the Visual Word Form Area in the brains of nine volunteers. This impaired their ability to read Braille, confirming the role of this site for the task. The results also discount the hypothesis that the visual cortex could have just been activated because volunteers used their imaginations to picture Braille dots.

“We are all capable of retuning our brains if we’re prepared to put the work in,” says Szwed.

He asserts that the findings call for a reassessment of our view of the functional organization of the human brain, which is more flexible than the brains of other primates.

“The extra flexibility that we have uncovered might be one those features that made us human, and allowed us to create a sophisticated culture, with pianos and Braille alphabet,” he says.

Barefoot to school… Clogher, Co Tyrone, Ireland, from the Rose Shaw collection

Since 2009, Ada Lovelace Day has aimed “to raise the profile of women in science, technology, engineering and maths by encouraging people around the world to talk about the women whose work they admire.”  The day’s namesake, Ada Lovelace (1815-1852), was the daughter of Lord Byron and Anne Isabella Milbanke.  Ada, in possession of a keen intellect and deep passion for machinery, was educated in mathematics at the insistence of her mother. Later in life, Ada studied the workings of the Analytical Engine developed by mathematician and inventor Charles Babbage. In her notes on the engine, Ada described an algorithm for computing numbers – an algorithm which would distinguish Ada as one of the world’s “first computer programmers.”  

In honor of Ada Lovelace Day, we present some images from the CHF Archives of women working in various chemistry labs. Click on each photo for additional information.

First genetic proof that women were Viking warriors

New DNA evidence uncovered by researchers at Uppsala University and Stockholm University shows that there were in fact female Viking warriors. The remains of an iconic Swedish Viking Age grave now reveal that war was not an activity exclusive to males – women could be found in the higher ranks at the battlefield.

The study was conducted on one of the most well-known graves from the Viking Age, a mid-10th century grave in Swedish Viking town Birka. The burial was excavated in the 1880s, revealing remains of a warrior surrounded by weapons, including a sword, armour-piercing arrows, and two horses. There was also a full set of gaming pieces and a gaming board.

The morphology of some skeletal traits have long suggested that she was a woman, but since this grave has been the type specimen for a Viking warrior for over a century, it has always been assumed to have belonged to a male Viking. Now, geneticists, archaeogeneticists and archaeologists have worked together and solved the mystery. DNA retrieved from the skeleton demonstrates that the individual carried two X chromosomes and no Y chromosome. Read more.
