  • The Time Has Come, for You to Lip-Sync, for Your Identity: Bridging the Queer
    The Time Has Come, For You to Lip-Sync, For Your Identity: Bridging the Queer Gap Between Theory and Practice Thesis RMA Musicology Vera van Buren (5539307) Feb- Aug 2019 RMA Musicology | Supervisor: Dr. Olga Panteleeva | Second reader: Dr. Judith Peraino Abstract The humanities seem to want to specialize in capturing the human experience in their socio-cultural context. It seems, however, that throughout the past decades, certain experiences are harder to academically pin down than others. The critique posed by queer people on queer theory is one example of this discrepancy. Judith Butler, Maggie Nelson, Sara Ahmed and Crystal Rasmussen are some authors who intellectually capture the experience of queerness. Especially Butler has received critique throughout her career that her description of queerness had very little to do with the real-lived experience of queer people. But, her work showed seminal in the deconstruction of gender identity, as did the works by the other mentioned authors. Despite the important works produced by these authors, it is still difficult to find academic works that are written with a ‘bottom-up’ approach: where the voices of oppressed groups are taken for the truth they speak, while academic references are only there to support their claims. In this thesis, I utilize this ‘bottom-up’ approach, testing through my case study—namely, the experiences of Dutch drag queens, specifically how they experience topics around lip-sync performances—to what extent their lived experience is in accordance with the theoretical works by which they are framed. Through interviews with Dutch drag queens, by attending drag shows, and by critically reviewing academic literature, I will test the discrepancy, or parallel, between the theory, and practice.

Dr. Divya V Shenoy¹, Dr. Nelly Nazareth² 1 (Postgraduate , Deparment of Ophthalmology, Father Muller Medical college Hosptial , India) 2 (Associate Professor, Department of Ophthalmology, Fathermuller Medical college Hospital , India) Corresponding author: Dr. Divya V Shenoy Abstract: Objective:To study the reversal of induced astigmatism by pterygium following its excision and conjunctival limbal autograft with no suture and no glue technique. Methods: 33 patients with nasal pterygium were included. All patients were examined and graded for the degree of pterygium, keratometry and visual acuity before and after the procedure. All patients underwent pterygium excision with conjunctival limbal autograft with no suture no glue technique by the same surgeon.Results :Amoung 33 patients ,16 patients with grade 1 and 17 with grade 2 were included.There was significant reduction of astigmatism post operatively in the form of reduction in the difference between K1 and K2 for Grade 1 (p= 0.001) and Grade 2 ptergia. (p< 0.001)The post operative difference of K1-K2 stabilizes at 1 month.Conclusion: There is significant improvement in post op visual acuity and induced astigmatism following pterygium excision .

Materials & Methods: Study was conducted on 25 patients whose age>30 yrs with thorough ocular examination and blood investigationsrequired for surgery. After peribulbar anesthesia, thin layer of conjunctival graft was fashioned from pterygium tissue .This conjunctival layer from the pterygium itself was then separated completely from the underlying fibrovascular tissue and kept onto the corneal surface then fibrovascular tissue was excised. Thin conjunctival layer was then transferred to bare sclera bed with epithelial side up and without any rotation and adhered to the bare sclera bed using fibrin blood clot Results: The study showed the patient has minimal recurrence rate, no graft oedema.

    "WEIRD AL" YANKOVIC: POLKAS, PARODIES AND THE POWER OF SATIRE By Chuck Miller Originally published in Goldmine #514 Al Yankovic strapped on his accordion, ready to perform. All he had to do was impress some talent directors, and he would be on The Gong Show, on stage with Chuck Barris and the Unknown Comic and Jaye P. Morgan and Gene Gene the Dancing Machine. "I was in college," said Yankovic, "and a friend and I drove down to LA for the day, and auditioned for The Gong Show. And we did a song called 'Mr. Frump in the Iron Lung.' And the audience seemed to enjoy it, but we never got called back. So we didn't make the cut for The Gong Show." But while the Unknown Co mic and Gene Gene the Dancing Machine are currently brain stumpers in 1970's trivia contests, the accordionist who failed the Gong Show taping became the biggest selling parodist and comedic recording artist of the past 30 years. His earliest parodies were recorded with an accordion in a men's room, but today, he and his band have replicated tracks so well one would think they borrowed the original master tape, wiped off the original vocalist, and superimposed Yankovic into the mix. And with MTV, MuchMusic, Dr. Demento and Radio Disney playing his songs right out of the box, Yankovic has reached a pinnacle of success and longevity most artists can only imagine. Alfred Yankovic was born in Lynwood, California on October 23, 1959. Seven years later, his parents bought him an accordion for his birthday.

  • Pigeucula and Pterygium
    What Is a Pinguecula and a Pterygium (Surfer's Eye)? Written By: Kierstan Boyd ​ Reviewed By: James M Huffman, MD ​ Oct. 29, 2020 Pinguecula and pterygium are growths on your eye’s conjunctiva, the clear covering over ​ ​ the white part of the eye. ​ ​ Pinguecula is a yellowish, raised growth on the conjunctiva. It’s usually on the side of the ​ ​ ​ eye near your nose, but can happen on the other side too. A pinguecula is a deposit of protein, fat, or calcium. Pterygium is a growth of fleshy tissue (has blood vessels) that may start as a pinguecula. It ​ can remain small or grow large enough to cover part of the cornea. When this happens, it ​ ​ can affect your vision. Both pinguecula and pterygium are believed to be caused by a combination of exposure to ultraviolet (UV) light from the sun, wind and dust. ​ Avoiding pinguecula and pterygium lf you have had a pinguecula or a pterygium at least once before, try to avoid the things that cause these growths. Here are some ways: ● wear sunglasses to protect your eyes from ultraviolet (UV) light ​ ​ ● protect your eyes from dust by wearing glasses or goggles ​ ​ ● use artificial tears when your eyes are dry ​ ​ Symptoms of pinguecula and pterygium can range from mild to severe. They include: ● redness and swelling of the conjunctiva, mostly while the pterygium grows ​ ​ ● a yellow spot or bump on the white of your eye ​ ● dry, itchy, burning eyes. Or feeling like sand or grit is stuck in your eye ​ ​ ​ ● blurry vision In many cases pinguecula and pterygium do not need to be treated.
