Exploring the Sacred Places in Our Communities: A Precis of an Article by Mark A. Graham

This is an article that is worth taking the time to find and read.  It is interesting and there are more than a few smiles related….

My Precis

Expanding personal and sacred place to include community, through art, can break down barriers and lead to the type of experiences and understanding that brings about responsibility and social change.

~~~

My Precis Expanded (a summary of the original article):

Research suggests that art education must have a compelling personal and cultural context if it is to succeed in creating new ways of thinking, knowing and representing. Artmaking in the classroom provides an opportunity to give form to the transformation and reshaping of ideas, experiences and materials into meaningful representations. This article describes the efforts that one group of students made to understand their community and history through art.  Our lives are often led within a fractured world that has become a place to be taken for granted, owned, used up, and discarded. Place-based education aims to bring together nature and communities by breaking down isolation and emphasizing responsibility.

Life is about possibilities and art connects life through associations.  Transcendent art can be filled with sacred images or images that the artist held sacred, thereby attaching meaning and revealing aspects of nature and reverence without religion. By making ecology of place the focus of their work, many contemporary artists are attempting to connect community and the preservation of the natural environment.  The aim of exploring and learning about the ocean, animals and trees that we share in our communities is to cultivate a thoughtful awareness and a sense of reverence towards our homes.

In a museum, detailed images are constructed and places depicted in order to build a vocabulary to further help us in the exploration of another’s place. To define sacred place through experience and memory, students were asked to share details of personal spaces that they considered sacred. In the area surrounding the school there is an 18th century graveyard as well as abandoned excavation sites, parkland and shoreline. Armed with sketchbooks and cameras to record nature’s resistance to America’s consumer culture, the students appeared in the classroom each Monday with a collection of images and questions. These questions facilitated discussions about home and homelessness and about our place in this world and our responsibility to others.

The students began a collage with photographs they had taken.  The photographs  were soon joined together into paintings as images of rocks, ocean, trees and street formed various personal meanings within the larger images. Borders that both connected and displaced became a theme and, as confidence grew, one student added family to her paintings and eliminated some of the isolation of displacement. A photographic collage of Main Street not only contained the sophistication of adolescent conversation caught up in music, fashion and identity, it was a reminder to us that a street is a panorama of architecture, trees and water connecting a small area (community) to the greater community of city, state and country. Bridges joined communities and in a collage, a bridge can also work to manipulate time by joining together the past and present.

The conversations and images came together in the final exhibition. Each student prepared and displayed a written commentary about their work. Each piece was mounted and hung in a sequence that included preliminary plans, sketches, studies, and final paintings.  The exhibition introduced other members of the community to our newly discovered sense of place and it was a success because it connected the artists (the students) with their environment (their home) on a level that brought awareness not only to them but to the community.

In order to understand our history we must learn it. Personal history can be found in our communities and in special places that help or have helped to shape our identities. Sharing, or teaching, is often referred to as the best way to learn and in this instance, visual art precipitated the sharing of personal interaction with sacred place.

Short Term Memory and The Power of Limited Thinking

Article:  The Power of Limited Thinking

My Precis

In the real world, small samples of information that fit with and within information we already possess, seem to give us the best chance of making accurate decisions.

 

~~~

My Precis Expanded (a summary of the original article):

As a newborn infant, we immediately begin to affect regular habits in order to survive. Learning to recognize action and reaction, movement and sound, helps us to quickly and consistently learn. As we begin to recognize meaning in a statement we begin to combine statements where one makes the other true. How obvious a statement is will depend on education and background.

Our short-term memories hold only a very limited number of “pieces” of information at one time, usually no more than six or eight. So, when a variable changes (when something happens), it amplifies the constants (and our understanding) of the world. Positively correlated events and a limited short-term working memory work together to help us to learn, especially when we are children and learning a first (native) language. An ability to detect positive correlations may help us to detect irregularities, even if we sometimes detect false correlations or set off false alarms.

In studies, inaccurate assumptions or perceptions interfere with our ability to connect events that really do go together and even scientists can overestimate significant relationships when they are dealing with small representative groups. There is a gamblers fallacy that states that a run of something (good or bad) will correct itself and that the odds will eventually even up. However, any random sequence, with the same variables, has an equal chance of being repeated. The ability to recognize positive correlations rises as working memory capacity declines. One study selected groups on the basis of their working memory capacity and found that the high capacity group chose the fewest false correlations but also the fewest positive correlations.

When looking at real world situations, small samples seem to allow us the best chance to make an accurately correlated decision based on available information and findings in studies show that limited knowledge can aid us in reaching decisions in uncertain circumstances. That built-in ‘amplifier’ locating positive correlations that seems to help infants to put together speech sounds and learn language suggests that the adult mind is designed to locate positive correlations and filter out the background noise.

Arctic Pollution from Unexpected Sources

A summary of the article, Sea Birds Fly Pollution to the Arctic, by Andreas von Bubnoff.

The Original Article:  Sea Birds Fly Pollution to the Arctic:  Bird Guano Makes for Hotspots of Toxins

My Precis

We know that pollution is being carried to the Arctic by wind and tides and now we also know, through scientific investigation and the testing of lake water, that pollution is carried into the Arctic by migrating birds.

~~~

My Precis Expanded:

Arctic lakes that are used by birds such as Northern Fulmars (Fulmarus glacialis) have been found to contain higher concentrations of toxins such as mercury, DDT, and hexachlorobenzen (HCB) than lakes with lower bird populations. To determine the extent that birds are bringing pollution with them, eleven Arctic lakes, located both near and at a distance from, nesting sites were tested for chemical pollutants. Some of these lakes were found to have very high mercury concentrations.

Birds eating contaminated prey or carrion become contaminated themselves as chemicals such as HCB, DDT and PCBs collect in an animal’s fatty tissues. These chemicals then pass on to other predators when the contaminated meat is eaten. Indigenous peoples living in the Arctic and relying on game for food are eating contaminated animals. “Mercury and PCBs can cause immune system dysfunction, adverse neurological effects and IQ deficits.”

Wind and sea currents are major sources of pollution in the Arctic. The best way to fix this problem is to prevent more contamination “from entering the environment in the first place.”

The Most Complete Titanosaur ever Discovered….

Sometimes it is simply the size of some of nature’s creatures leaves me in awe…  And, it was still growing!  Wow!

Lacovara, K.J., Lamanna, M.C., Ibiricu, L.M., Poole, J.C., Schroeter, E.R., Ullmann, P.V., Voegele, K.K., Boles, Z.M., Carter, A.M., Fowler, E.K., Egerton, V.M., Moyer, A.E., Coughenour, C.L., Schein, J.P., Harris, J.D., Martinez, R.D., & Novas, F.E.  2014. A Gigantic, Exceptionally Complete Titanosaurian Sauropod Dinosaur from Southern Patagonia, Argentina. Scientific Reports 4 (6196).

My Precis

The 2/3’s complete skeleton of a titanosaur, Dreadnoughtus schrani, found recently in Argentina, would have been approximately 26m in length and weighed 593 metric tons and, may have still been growing when it died.

My Precis Expanded

Not much is known or understood about titanosaurs, the largest of the dinosaurs, as the only skeletons that have been found have been fragmentary, frustrating attempts to estimate size and other characteristics but the recent discovery of a titanosaur in Argentina has given scientists an almost 2/3’s complete and extremely well preserved skeleton to work with. This is the most complete titanosaur ever found and was given the name Dreadnoughtus schrani; Dreadnought from Old English, meaning ‘fearing nothing’. Schrani, honouring Adam Schran for his support of this research.

When the skeleton of Dreadnoughtus was compared to the skeletons of other titanosaurs, differences in the shapes and sizes of the bones were found that make Dreadnoughtus unique. This is one of the largest of these giants with an estimated length of 26m and a weight of 593 metric tons. Examinations of the bones have revealed that even at this size, this titanosaur may still have been growing!

Exploration Before Population – A Precis on a Hospital Microbiome Study Planning Session

I heard about the microbiome study and did a quick search, printed something out (these aren’t always easy to find) and added the article to my reading pile.  I don’t read at the computer.  I find that it is kind of like trying to read the writing on a light bulb – while the bulb is turned on….  My screen is turned down quite a bit but, that just delays the reading fatigue.  Hmmm…. maybe there is an article on this?

Anyways, the paper I printed turned out to be the minutes of a meeting on the planning of the hospital microbiome project at the University of Chicago Medical Center.  It is an interesting read!

 

The Article:

Smith, D., Alverdy, J., An, G., Coleman, M., Garcia-Houchins, S., Green, J., Keegan, K., Kelley, S.T., Kirkup, B.C., Kociolek, L., Levin, H., Landon, E., Olsiewski, P., Knight, R., Siegel, J., Weber, S., and Gilbert, J.  2013.  The Hospital Microbiome Project:  Meeting Report for the 1st Hospital Microbiome Project Workshop on Sampling Design and Building Science Measurements, Chicago, USA, June 7th-8th 2012.  Standards in Genomic Sciences  8(1), 112-117.  Published Online Apr 15, 2013.  doi:  10.4056/sigs.3717348

 

My Precis

This is a planning discussion for a study that will sample the environment of a hospital and its occupants, beginning before construction is complete to look at how hospital acquired infections are contracted and transmitted.

 

My Precis Expanded:

A lack of research into how hospital acquired infections are acquired and transmitted has prompted an investigation in a new hospital pavilion with the research scheduled to begin before the pavilion opens. When the building opens the building itself will then be exposed to health care workers, patients and visitors. This paper discusses how a systematic exploration, beginning with the architectural design and maintenance of the building and utilities could be used to track the progress of microbial community succession.

The planning meeting of this long-term research project included discussion on the architectural design and maintenance of the building and utilities as well as the materials and processes used and to be used. It was decided that two rooms were to be sampled daily and another 18 rooms on a weekly schedule and that the schedule would include the collecting of any “samples of interest.” The current tracking of staff between rooms and staff self-tracking in their usage of items such as glove boxes was added to the sampling schedules.

Another meeting will be held after the project has begun.
