Whats Wrong with Every Circus Story
Whatâs Wrong with Every Circus Story This is a guest post from Mary Kay McBrayer. Mary Kay is a belly-dancer, horror enthusiast, sideshow lover, prose writer, Christian, and literature professor from south of Atlanta. Mary Kay founded the horror and comedy blog and podcast Everything Trying to Kill You, and she is also the creative nonfiction editor for Madcap Review, a semi-annual online journal of art and literature. She is currently working on her first full-length novel about Americaâs actual first female serial killer, but until then you can read her essays at Chicago Literati, Prick of the Spindle, Book Squad Goals, and The Blueshift Journal. She is not an animal person. Follow her on Twitter @mkmcbrayer. When I saw the trailer for The Greatest Showman, I was super-pumped to see it. Most of my research over the past few years has been about the circus, and in particular the sideshow. So when I saw ads for a fictionalized, musical biopic about the life of P.T. Barnum, I was like, sign me up. Hereâs the thing it was missing, just like all the other fictional circus books I know and love: we seldom get to hear the performersâ stories from the perspective of the performers. I know that Phineas Barnumâs main deal was to spin the storyâ"that was his whole schtick, and I get it. Ham it up because people love a good story. Yes. Iâm not saying I need the performersâ story to be the true storyâ"I love a tall tale as much as the next guy! I really do! If your true story sucks, lie to me. Iâm fine with all of that. Give me the ballyhoo. Tell me a different origin story. Make yourself into a cryptid. By all and any means necessary, give me a narrative. The thing is, the performers just hardly ever get to tell their own lies. They just seem to have stories told about their experience for them. When you get to tell your own lies, at least theyâre your own. They may not be true, but theyâre still yours. More so, maybe, because you created them. Anyway, I tried to think of an instance in my favorite circus sideshow fictions in which the performer talked his or her own story, but I came up short. My favorite novel is Kathryn Dunnâs Geek Love, and even though the story is told from the perspective of one of the freaks (their term), the narrator is not a performer. In Erika Swylerâs Book of Speculation, too, we only get stories from wannabe performers, never the one in the tank. The narrator of the current timeline doesnât even believe in his own gimmick, so itâs definitely not a narrative from the perspective of a performer. Even in Big Fish, Carl the Giant doesnât get his own narrative. Heâs just a plot device that Edward Bloom gets to utilize in telling his own talesâ"he gets a cameo in someone elseâs story. I just got so frustrated that the performers, especially those with anomalous bodies, and ESPECIALLY especially those with anomalous bodies who were also of color, just never get to tell their own stories. Or, at least, I havenât been able to find their own stories as told by them, unless you count cartes des visites, like this one: These were souvenirs that the audience could buy at the sideshow to put in their scrapbook, and then when they hosted a party theyâd have something to talk about. They were hustled as True Stories, and at the time, people bought those stories, both literally and figuratively. I think we can all agree that their captions are somewhat (if not totally) fictionalized, now, though, so I think the photos and their margins fit my parameters. How dope would it be now to hear those stories As Told By, though? Even if fictional. Those cards were usually scripted and rebranded by the talkers to be more exotic (again, their words). To my knowledge, Iâve been able to find precious few fictional re-workings of performers as told by performers, and that makes me ill. I could be missing something crucial thoughâ"and if I am, PLEASE let me know. Seriously, Iâve been hunting for it. So. Please. Let me know. But I donât want you to think that Iâm part of the problem! If I canât find what I want to read, I keep looking. And when I still canât find it what I want to read, I try to write it myself!

The Great Depression During World War I - 1943 Words
The 1920ââ¬â¢s in American history, characterized by its social, artistic and cultural vitality, and is known as the roaring twenties. The U.S. economy was the largest industrial in the world, thus it provided significant help to European nations that experienced debt after World War I. Throughout this prosperous era, many rich Americans made large profits from businesses that they owned. A majority of Americans started to spend more money than they earned which would inevitably lead to major problems in the future. On October 29, 1929, which is known as Black Tuesday, the stock market crashed. The Great Depression began and proved to be a worldwide phenomenon. Domestically as well as internationally, the dramatic effects of the depression worked as a domino effect as all banks and other businesses fell almost instantaneously.

Jean Piaget (1896-1980) Was A Cognitive Constructivist
Jean Piaget (1896-1980) was a cognitive constructivist born in Neuchatel, Switzerland. He played a huge role in how we view child development and how we can apply it to teaching in our classrooms. A set of cognitive developmental stages were developed by Piaget to explain how, when and where a childââ¬â¢s development takes place. Cognitive development is crucial, if a child does not develop cognitively then he or she would not be able to reason, interpret, speak, think, understand, remember etc. However, it is important to remember that cognitive development happens over time and that it cannot be forced onto a child. Piaget believed that human beings build ââ¬Ëschemesââ¬â¢ (actions or action patterns that deal with the environment) that allow us toâ⬠¦show more contentâ⬠¦An infantââ¬â¢s scheme, during this stage, is limited to what he or she can explore through their senses. This stage is called the sensori-motor stage. It is also divided into sub-stages such as reflexes(an action or movement performed without conscious thought as a response to the stimuli), primary circular reactions(exploring the environment by repeating a pleasurable action centred around his or hers own body, such as sucking their thumb), secondary circular reactions(an intentional act is acted out with an object outside of his or body in order to receive a response from the external environment), coordinated secondary scheme(the infants actions become more goal specific in order to overcome obstacles), tertiary circular reactions(when an infant would start experimenting with different actions in order for them to observe what the different possible outcomes would be), symbolic thought(the infant would use an object to try and recreate a moment or event of the past), imitation(children will start their exploration of their environment and will often copy or follow someone or something) and object permanence(an important ability needed to be able to construct a mental representation. An understanding that objects exist in the environment whether they are able to see them or not and is acquired gradually over a period of time. However, object permanence is not fully mastered before the age of 18months).

How to Use the Rack Application in Ruby
In the previous article, you learned what Rack is. Now, itââ¬â¢s time to start using Rack and serve up some pages. Hello World First, letââ¬â¢s start with a ââ¬Å"Hello worldâ⬠application. This application will, no matter what type of request itââ¬â¢s given, return ââ¬â¹with a status code of 200 (which is HTTP-speak for ââ¬Å"OKâ⬠) and the string â⬠Hello worldâ⬠as the body. Before examining the following code, consider again the requirements that any Rack application must meet. A Rack application is any Ruby object that responds to the call method, takes a single hash parameter and returns an array containing the response status code, HTTP response headers and the response body as an array of strings. class HelloWorlddef call(env)return [200, {}, [Hello world!]]endend As you can see, an object of the type HelloWorld will meet all of these requirements. It does so in a very minimal and not terribly useful way, but it does meet all of the requirements. WEBrick Thatââ¬â¢s pretty simple, now letââ¬â¢s plug it into WEBrick (the HTTP server that comes with Ruby). To do this, we use the Rack::Handler::WEBrick.run method, pass it an instance of HelloWorld and the port to run on. A WEBrick server will now be running, and Rack will be passing requests between the HTTP server and your application. Note, this isnââ¬â¢t an ideal way to launch things with Rack. Its only shown here to get something running before diving into another feature of Rack called Rackup, which is shown below. Using Rack::Handler in this way has a few problems. First, itââ¬â¢s not very configurable. Everything is hard-coded into the script. Second, as youââ¬â¢ll notice if you run the following script, you canââ¬â¢t kill the program. It wonââ¬â¢t respond to Ctrl-C. If you run this command, simply close the terminal window and open a new one. #!/usr/bin/env rubyrequire rackclass HelloWorlddef call(env)return [200, {}, [Hello world!]]endendRack::Handler::WEBrick.run(HelloWorld.new,:Port 9000) Rackup While this is quite easy to do, it isnââ¬â¢t how Rack is normally used. Rack is normally used with a tool called rackup. Rackup does more or less what was in the bottom section of the code above, but in a more usable way. Rackup is run from the command-line, and is given a .ru ââ¬Å"Rackup file.â⬠This is just a Ruby script that, among other things, feeds an application to Rackup. A very basic Rackup file for the above would look something like this. class HelloWorlddef call(env)return [200,{Content-Type text/html},[Hello world!]]endendrun HelloWorld.new First, we had to make one tiny change to the HelloWorld class. Rackup is running a middleware app called Rack::Lint that sanity-checks responses. All HTTP responses should have a Content-Type header, so that was added. Then, the last line just creates an instance of the app and passes it to the run method. Ideally, your application shouldnââ¬â¢t be written entirely within the Rackup file, this file should require your application into it and create an instance of it that way. The Rackup file is just ââ¬Å"glue,â⬠no real application code should be there. If you run the command rackup helloworld.ru, itââ¬â¢ll start a server on port 9292. This is the default Rackup port. Rackup has some more useful features. First, things like the port can be changed on the command line, or in a special line in the script. On the command-line, simply pass in a -p port parameter. For example: rackup -p 1337 helloworld.ru. From the script itself, if the first line starts with #\, then itââ¬â¢s parsed just like the command line. So you can define options here as well. If you wanted to run on port 1337, the first line of the Rackup file could read #\ -p 1337.
