Dirty Dancing and Jazz

Links and BackLinks

 

Broadway & Vocal Jazz in America

Two live events in America enthralled us: 1) Broadway show and 2) A Capella Vocal Jazz. Our son Dr. Arjun Sengupta of Ohio State University gave us the first surprise by getting tickets to a Broadway show. We consider ourselves lucky that our first outing to a Broadway musical was on a Hollywood blockbuster ‘Dirty Dancing’. It was held at the Ohio State Theater, Downtown, Off High Street, Columbus. The grandeur of the theater hall and a packed gathering were the first things that impressed us. And after that it was just like getting carried away by the performance. At the end it crescendoed with the lilting song of Dirty Dancing ‘I have had the time of my life…’.A thousand splendid lights synced with the song pulsated and danced, grazing the audience and sweeping up and down the enormous cavernous space in the hall showed a novel way of involving audience participation with the artistes on stage. My wife’s friend Anita Chowdhury, our host at New Jersey, was keen on showing a live event. Since we saw a Broadway musical, we opted for a Jazz show. Anita and her husband Sidhu received us at Greyhound Bus Station in China Town, Philadelphia. From there they took us to ‘Victory Bell’ and then for a brief ride through Philadelphia streets, before heading for their house at East Brunswick. We were hungry by the time we reached Anita’s sprawling bungalow. Some culinary delights prepared by Anita awaited us. And we literally gorged on our welcome lunch. Especially the salmon preparation was delectable. At 8 pm we reached Taplin Auditorium, Princeton University to watch yet another grand American event ‘A Capella Vocal Jazz’.Enroute we were fortunate to see the house where Albert Einstein lived. The vocal jazz was something new and unique to us as the jazz numbers were rendered by vocalists without support of any accompanying music. It was all male a Capella. There were two groups , the Fonic – a five man vocal band based in New York City blending pop, rock and soul; and Break from Blue Collar, a quartet from Lancaster, PA with fresh interpretations of barbershop classics and the exciting sounds of rock & roll. It was a part of Princeton Festival and some of the popular jazz numbers rendered were ‘When I’m 64’, ‘Hallelujah’, ‘Zombie Jamboree’, ‘Drip Drop’, ‘Fools Paradise’. The unique baritonal quality of their voices fulfilled the essence of a jazz program. After the show the audience had a wonderful interactive session with the artistes over wine and preparations of cheese, bacon, sausage etc. We came back fully satisfied with feelings that we have been able to see yet another great American event.

Cafe Leaves n Aroma --- Adda with Great Tastes



Not very far from the din,bustle and squabbles of Calcutta lies another Calcutta. A new Calcutta-Kolkata comprising Rajarhat and New Town. A newly developed Park known as Eco Park is located here. We bumped into it recently on our way back from the airport. Built on the concept of providing eco-friendly atmosphere it houses amongst other attractions an exclusive and unique Butterfly Park. Nature lovers can catch a glimpse and observe the behavior of a wide variety of butterflies and moths. Way to the Park saw us at a culinary stopover ‘Leaves n Aroma’, a cute little café seated a few meters from the Eco-Park entrance gate. Run by Ms Mitali Mitra and Ms Sunetra Chaudhury, the inside décor is simple and warm. We were greeted by Mitali, a former journalist. Bubbling with ideas she has effectively all the ingredients in place to create the nostalgic café culture of seventies. A book rack with some very interesting collection is an added attraction for avid readers, like my wife, who would enjoy leafing through pages over a cup of piping hot Darjeeling tea. Being a connoisseur of tea, I always enjoy indulging on prolonged sips if I find it to my satisfaction. And then there is something decadent and sumptuous for everyone’s individual taste and personality – that is what Mitali strives to achieve. However, on the Menu you will find from a savory Aloo Paratha with Tomato Chutney or with curd and pickle, Methi Paratha, Chicken Nuggets, Finger Chips, a wide variety of cakes. And for those who prefer health food in the eco- surrounding there is a tempting choice of oil free finger chips, nuggets and peanut pakodas. One day we have to try out Luchi Sabji / Dal, which they normally serve during breakfast hours. But what satisfied me most is the discovery of yet another new ‘Adda’ joint in Calcutta. Being an ‘AddaBaaz’ and ‘Adda’ lover I always prefer ‘Adda’ in tranquil surroundings, and that’s where ‘Leaves & Aroma’ scores over others.

LIGHT ON EYE AND VISION

Links and BackLinks
Eye, Vision , Light
Eye is precious. And Vision is more precious. We must all take utmost care of both eye and vision.The main features of the eye and images of what might be seen in case of three most common eye problems we get afflicted with  are illustrated here. In a recently concluded international conference Lux Pacifica 2015 on Lighting held in Calcutta, a very interesting and revealing paper on the role of Lighting to Eye and Vision was presented by Prof. Warren Julian of Sydney University.It has evoked so much of interest in me that I thought of sharing it with you all to create awareness amongst all my readers. You will find below the excerpts from Prof. Julian's paper.

Partial sight / low vision
Partial sight (or low vision) refers to a permanent condition of
diminished visual performance which cannot be rectified by
routine refraction and which is intermediary between normal
vision and blindness.
Typically, even with best spectacle correction, the affected
person cannot read a newspaper at a normal reading distance
(400 mm) but often has no orientation and walking problems.
The clinically most affected visual function is often visual
acuity but can also be visual field and/or contrast sensitivity.
Although there is no generally accepted single definition of
partial sight, an uncorrectable central vision of the better eye
of between 0.3 (20/60) and 0.02 (20/1000) is the visual acuity
criterion most commonly used.
In many countries “legal blindness” is defined as
corresponding to a reduction of visual acuity of the better eye
to less than 0.1 (2/20). Thus, a part of the partially sighted are
legally blind.


The University of Sydney Page 5
Prevalence and incidence
In most developed nations, the prevalence of legal blindness
is in the order of 0.2%.
The incidence is about one-tenth of the prevalence; ie, the
incidence of legal blindness is in the order of 0.02%.
Statistics from the US suggest that, within the legally blind
group, only about 15 to 25% are found to be functionally blind:
ie, at least three-quarters of the legally blind population have
useful vision.
The group that has low vision and is not legally blind is about
3 to 4 times larger than the legally blind population. Thus, in
the US, the prevalence of visual handicap is about 0.8 to 1.0%
of the total population, and its incidence about 0.1%.
Converting for India (conservatively): 13,000,000 with low
vision with 1,300,000 new cases per year.
Around 70% are over 65 years, in developed nations.

The University of Sydney Page 6
Causes
Australia (Dowling, 1980)
cataract 38%
retinal deterioration 22%
glaucoma 21%
vascular conditions 8%
diabetes 7%
other 11%
This is for developed nations where the three major causes of
partial sight are diseases which usually appear late in life.
However, for the world’s population, the causes of blindness
change from the diseases of age to disease related to public
health, malnutrition, parasitic attack and accidents.
The 6 main causes of world blindness are trachoma (bacterial
infection), onchocerciasis (parasitic worm), blinding malnutrition,
cataract, glaucoma and trauma.

Multiple handicaps
Age-related maculopathy and diabetic retinopathy. These
require high illumination but often less when cataracts develop
because intense illumination causes glare and constriction of
the pupil, further impairing vision.
Both glaucoma and age-related maculopathy are more
prevalent in the elderly and sometimes they occur within the
one eye. Both conditions often cause a need for greater
illumination but glaucoma medication pilocarpine causes
constriction of the pupil demanding more illumination.
Visual impairment associated with impairments in other
systems is particularly frequent in persons more than age 65
in whom sensory and physical disorders as a consequence of
aging become more prevalent.
Many aged partially sighted persons do not even identify poor
sight among their major problems, being overwhelmed by
other disabilities. These include cardiovascular, arthritic and
neurologic (hand tremor, sequellae of cerebrovascular
accidents). Hearing loss is also frequent.


The University of Sydney Page 13
Impact of low vision
Human beings are constantly involved in negotiations
between themselves and their physical and social
environments. Information is received by the senses: that
information is then processed — it is given meaning through
interpretation, organisation and classification.
Orientation and mobility involve becoming aware of the nature
and location of major features in the immediate environment
and being able to safely navigate while travelling purposefully
from one place to another.
Reading and writing are important in modern society and for
most individuals, even for private life (reading personal
correspondence, financial documents, labels, price tags,
telephone directories, etc.).
Participating in society involves interactions with and
observation of other human beings.


The University of Sydney Page 14
Impact of low vision 2
Visually-guided manipulative tasks include the preparation
and eating of food, performing household repairs and
maintenance, repairing and maintaining clothing, and selfgrooming.
Manipulative tasks can be an important part of
recreation, eg, sewing, knitting, carpentry, metalwork,
mechanical assembly, etc.
The appreciation of visual beauty necessarily becomes
restricted when there is visual loss.
Factors in addition to partial sight can affect the behaviour of
partially sighted people, including age, associated non-visual
handicaps, living conditions or occupations, age of onset of
the visual loss, intelligence, mental orientation, education,
motivation and training.
Partially sighted people can develop postural characteristics
which may seem unacceptable to the normally sighted
population. Such mannerisms as screwing up the eyes,
holding the head on one side, not looking at an individual
during conversation, always looking down when walking, etc.


The University of Sydney Page 15
Light lovers and haters
Light lovers are those who obtain better
vision by higher illuminances by two
means: improvement in visual acuity due
to higher E and greater depth of field due to smaller pupil
diameter. There can also be an improvement in contrast
sensitivity.
Higher E is only useful if glare, most particularly disability
glare, is controlled. Glare increases intra-ocular scatter,
reducing contrasts.
Light haters are those sensitive to photopic (normal) light
levels. They often have diseases affecting the receptors,
eg, retinitis pigmentosa and albinism. They often need to
wear dark glasses indoors to reduce luminances. Very
glare sensitive. More light is usually unhelpful

The University of Sydney Page 16

Design for seeing: common sense
We see only by contrast — brightness and/or colour contrast
Can see if critical detail is large enough (at resolution available)
Create contrast by using surface finishes (independent of light direction)
Allow/put light into scene so that extent can be seen unambiguously
Use pattern to reveal objects of importance, safety, etc. Door frame.
Do not use camouflage (eg carpeted stairs), vomit pattern carpets/vinyls.
Make edges obvious (we see by detecting edges)
