Tutors Theorizing the Writing Center :: Education Learning Papers

Central to the theorizing that is current in writing center scholarship is the concept of collaboration between tutors and students. Because of the overarching framework of social constructivism that currently drives theorizing in a multitude of disciplines—e.g., composition, literature, history, sociology, anthropology—it is not surprising that writing center scholars also use this framework to question the kind of knowledge that tutors create in tutorial sessions (see Grimm 1999, Murphy 1995, Carino 1995, Hobson 1994). Are tutors simply replicating the hierarchical paradigms of knowledge construction in which academia seems to be fully invested? Or are they capable of "thinking outside the box" because they are peers rather than teachers? My interest in how tutors theorize their practice in the writing center and how the writing center literature theorizes itself has been central to my work as a writing center director for the past 10 years. The small liberal arts college where I teach and direct the writing center has a staff of all-female undergraduate tutors, and I am constantly surprised by their fresh take on writing center theory and practice. They are bright and they question everything. Since this is exactly what a women’s college should be teaching young women to do, I encourage that stance in our writing center, and especially in the course tutors are required to take with me before they begin tutoring. In this paper, I will examine tutors’ journal responses written during a tutor training class held in the Fall of 2003. In these responses, tutors respond directly to articles which are often considered central to understanding the concepts of collaboration, control, socially constructed knowled ge, and the writing center as a site of resistance--concepts upon which writing center theory is often built. An important aspect of these journals is that they are dialogic. That is, they are entered on a Blackboard discussion forum that allows each tutor to read the other tutors’ journals and respond to them. The tutors’ responses seem to reveal a gap between what tutors understand about their own tutorial practices and what theorists believe to be true. In examining the tutors’ responses, I find that theorists sometimes recast practice to fit their theoretical constructs; as a result, tutors do not always see the same connections between theory and practice that theorists do. By listening to tutors’ voices as they critique writing center theory, I believe we can better understand how to use theory as a jumping off place for tutor training, rather than as an ending point.

Mine Sweeping System Using Image Processing

MINE SWEEPING SYSTEM USING IMAGE Processing Abstractions: Mine sweeping system is entirely designed for observing mines in peculiar user defined country. It uses a Java application from the user country and besides it consists of automaton which plays a cardinal function in the full system. The Java application and the automaton system works together to give an efficient system. The Java application is besides known as waiter and the automaton system communicate each other through wireless transmittal. In this system the human contact with the automaton is non required. The Java application is used to command the full mine sensing procedure. The optical flow vector, the automaton alliance and practical map of the location of the automatons are displayed on the screen of the waiter computing machine. Besides, the antecedently consequences that is the automatons that has searched for mines will besides be available or displayed for the user. So, that no demand of hunt for mines once more and once more in same country or practical grid. The ob tained database consequences are so uses to optimise thee mine brushing procedures in the hereafter through a LRU ( Least late used ) algorithm. The Robot system is aligned with a camera and uses a self-navigating algorithm with the obstruction turning away implemented utilizing optical flow. The optical flow which is produced within the milieus of the automaton system is registered utilizing the on board camera and by utilizing image processing methods like Image cleavage, Edge sensing and grouping, average filtrating thresholding procedure and by the vector computations, the hacking can be obtained. The automatons will work in a spontaneous practical grid and a existent clip map of the mine sweeping operation is displayed on the waiter system. Actually, the automatons will cipher the really shortest way within the grid while seeking and observing for the mines. The automatons commune with each other utilizing swarm engineering in order to carry through the undertaking. Introduction: The robotic usage of this mine sensing is a new procedure whereas the procedure of mine sensing is chiefly carried over by the worlds itself. They used to have on some protective cogwheel and some instruments with which they detect mines. There is a batch of hazard involved in this manner of mine sensing as no 1 can think the happening or the appendage of the blast. Hence so the usage of manual automatons in which they are guided by a user to observe or study a peculiar 1 for a mines therefore came into being. But these manner of observing mines was non much helpful as the manual navigate of the automaton of a certain country becomes tiresome largely over a big terrain. Therefore the demand for automatic automaton comes over when the user is non all required in voyaging the automaton. The robot hunt in a given country for the mines and the co-ordinates of their places are often sent to the waiter system. These automatons are plotted of a practical grid which is produced on the waiter system and their location can be tracked down. When a mine is detected the co-ordinate is sent back to the sever system and the symbol is marked on the practical grid denominating the sensing of mine such as co-ordinates, topographic point, clip, country all stored in the database. The user can so analyze the database to acquire the necessary information narrow down the hunt country. We used methods such as shortest way algorithm and chiefly image processing for obstruction turning away. Engagement of homo in the full sensing is non at all needed or zero. CONCEPTS AND FEATURES Optical flow Optical flow or ocular flow is the form of evident gesture of objects, surfaces and borders in a ocular scene caused by the comparative gesture between an perceiver and the scene [ 1 ] Optical flow computation utilizing Lucas cascade method The gesture of borders, surfaces and objects in a scene which raised by the gesture between an perceiver and scene is known as optical flow. The optical flow can be applied is obstacle turning away and self-alignment of driving circuit of the automaton. Calculation of optical flow Let us see two frames of clip T and a?† t at a place. The optical flow is calculated between this frames with the aid of a Taylor series method by utilizing partial derivation based on spacial and temporal coordnates. For a 2D+Tdimensional instance ( 3D orN-D instances are similar ) a voxel at locationwith strengthwill hold moved by,andbetween the two image frames, and the followersbrightness stability restraintcan be given: Assuming the motion to be little, the image restraint atwithTaylor seriescan be developed to acquire: H.O.T. From these equations it follows that: or which consequences in whereare theandconstituents of the speed or optical flow ofand,andare the derived functions of the image atin the corresponding waies.,andcan be written for the derived functions in the followers. Therefore: or [ 1 ] & A ; [ 2 ] This is an equation in two terra incognitas and can non be solved as such. This is known as theaperture problemof the optical flow algorithms. To happen the optical flow another set of equations is needed, given by some extra restraint. All optical flow methods introduce extra conditions for gauging the existent flow. In the mine sensing procedure optical flow is used for chiefly observing the object, hacking and besides for the robot pilotage. IMAGE SEGMENTATION Image cleavage is the procedure of partitioning a digital image into multiple sections which are sets of pels, besides known as ace pels. The end of cleavage is the simplify and/or alteration the representation of an image into something that is more pregnant full and easier to analyse. Image cleavage is typically used to turn up objects and boundaries which include lines, curves. In image more exactly image cleavage is the procedure of delegating a label to every pel in an image such that pels with the same label portion certain features. The basic measure for image retrieval by mercantile establishment is the computation of the ocular characteristics. The necessity to observe the object as a whole and non merely portion of it has been approved utilizing a intercrossed cleavage technique based on border sensing, part growth and optical flow processs. Image cleavage proves to be an of import measure in ciphering the navigational consequences of the automaton system. [ 1 ] & A ; [ 2 ] . Detection is based on object colour or strength contrast with the environing background. Regardless of the type of detector noise is ever present for cut downing these types of noises we use assorted types of filters. Median Filter Medium filter is a nonlinear method used to have noise from images. It is widely used as it is really effectual at taking noise while continuing borders. The average filter plants by traveling through the image pel by pel, replacing each value with the average value of vicinity pels. The form of neighbours is called the window, which pixel by pel over the full image. The median is calculated first screening all the pel values from the window into numerical over, and so replacing the pel being considered with the in-between pel value [ 3 ] Threshold Method It is besides known as image threshold. In this method, we introduce a new mechanism for observing the landmine. We merely convert the grayscale and cold images into binary or block/white images with specific threshold value or may be varies. Atmega 32 microcontroller The microcontroller we use in the mine sensing procedure for cryptography is the Atmega 32 which has characteristics such as.High public presentation, low power Atmel 8-bit micro accountantAdvanced RISC architecture133 powerful instructions- most signal clock rhythm executing32Ãâ€"8 general intent working registry + peripheral control registryFully inactive operation [ ]The microcontroller along with the L298 will be used to run the automaton automatically. Figure: Atmega 32 Microcontroller constellation Xbee pro communicating faculty The interaction between the automaton system and waiter system is formed through a Xbee faculty which acts as a trans receiver by procuring consecutive communicating utilizing the UART [ ] . Consecutive Communicationss The Xbee/Xbee-pro RF faculties interface to a host device through a logic – degree asynchronous consecutive port. Through its consecutive port the faculty can interact with any logic and electromotive force compatible VART ; or through a degree transcriber to any consecutive device. UART informations flow Devicess that have a vart interface can link straight to the pins of the RF faculty. Figure: UART environment Xbee pro system Flow Control DI ( Data In ) Buffer When the consecutive information enters RF faculty through the DI pin, the information is stood in the DI buffer until it can be processed. Hardware flow control ( CTS ) when the DI buffer is 17bytes off from being full ; by default, the faculty assert CTS to signal to the host device to halt directing informations CTS is re – asserted after the DI buffer has 34 bytes of memory available. Flow control DO ( Data Out ) When the RF information is received, the informations so enters the DO buffer and is sent out the consecutive point to a host device. Once the DO buffer reduces capacity, any extra entrance RF information is lost. Hardware flow control ( RTS ) : If RTs is enabled for flow control, informations will non be sent out the DO buffer every bit long as RTS is de- asserted. Therefore in this manner Xbee pro faculty questions to be an efficient trans receiver which initiates a 2nd VART channel. We create a templet foremost to carry through the papers processing demands. The others services will merely necessitate individual clip activation. SYSTEM DESIGN: The full mine sweeping system is categorized into three parts. They are:Waiter with Java ApplicationRobot system with drove engineeringWireless communicating system Figure: Block diagram system of Mine brushing Figure: Microcontroller and architecture communicating Figure: On Board camera and system communicatingWith the aid of net beans application the user controls the full system. At first the user writes a â€Å"start† bid in the Java application. Data will be send to the UART channel through wireless consecutive communicating.The start bid is received by the GB Xbee faculty on the automaton system and it triggers the micro accountant.After triping the micro accountant it invariably transmit a signal to the driving circuit with the aid of UART channel which portray the practical grid.The alterations are deciphered by the Java application and it was created on GEY at the same clip.This methodological analysis proceeds the circuit until the automaton achieves at the terminal of the self-created practical map.When the micro accountant is triggered it sends informations non merely to the drive circuit but besides to on board IP camera through a radio web device ( router ) to get down the image processing faculty.After triping of the IP c amera it captures the images of the practical grid and so it sends the information to the image processing faculty in which image cleavage optical flow consequences are generated.After finishing of the cringle the automaton sends a â€Å"stop† bid to the waiter.Software demands specification To put to death the mine sweeping system the user foremost enter the applicationThe automaton starts its procedure of seeking when it receives bid from the waiterThe automaton more over follows a optical flow which can be obtained by utilizing the on board IP camera. With the aid of optical flow method the automaton can avoid the obstructions and it itself align a practical map.The automaton so selects a shortest way on the practical grid to observe the mines.In this procedure the camera gaining control the image and the informations will be send to the image processing faculty in which mines can be detected by image cleavage procedure.After the image cleavage the information will be send to the waiter and shop in a information base.Here LRU algorithm is used to better the mine searching, observing and efficiency.Premises The distance between the client and the automaton should non be exceeded more than 500mtrs for good consequences. Dependences The connexion strength of UART is changeless. The automaton system must hold a changeless power supply all the times for accurate consequences. System characteristics The system consists of different characteristics to individual the operations. They are chiefly divided into: – Database Storage In this system this database storage plays a chief function. This storage system is used to hive away the images which was taken by on board camera. Here SQL database is developed and used to hive away consequences the automaton system and with the aid of JDBC connexion it was connected to java application Precedences With the aid of database the information will be stored manipulate and updated all the informations performed by the automaton is on the constituents. The illustrations are mine figure, location or country, count of mines etc. FunctionalRequirements The functional demands are nil but characteristics which are provided to stop users the full system has 3 bomber faculties they areJava application facultyImage processing facultyRobot facultyJava application faculty Java faculty is chief portion in the system from this lone the user starts the procedure by come ining the country of practical grid with this application we can besides see the full map with the aid of UART in which automaton performs operations. After finishing operations the applications shows the consequence for users java beans 7.0 is used to develop this application. Image processing faculty This faculty plays an of import key in the full system. By this the designation and localisation of mines was done. Here by utilizing image cleavage the mark is identified by the size form and visual aspect, this procedure is done by labelling procedure. In the image cleavage at first the gaining control image is labeled in to parts and so it converted in to black and white image so it subdivide the image harmonizing at that place sizes, forms and constructions. By utilizing these features the mark can be estimated of a mark assurance degree. Image cleavage is non sufficient for placing the mines so we use different mine field forms which can be find in survived part. Robot system faculty Thisconsists of micro accountant which generates the map and performs the operation when user gives a bid. Safety and Security RequirementsDue to connexion failures and micro accountant lapses the system may be crashed to over this state of affairs the robot resets and show approximately message to the user.The radio web is based on SSID user and watchword, which consists of unafraid connexion.ApplicationsIt consist of user friendly GUI.Known human contact is needed.All the communicating is through radio and web.The user can manually overrule the system.Conclusion The chief of the research is to develop a system which has a capableness of finding an object or mine. Here we used feeling techniques image cleavage and acknowledgment and faculties

Freedmen’s Bureau Act of 1865 Essay

The Freedmen’s Bureau was a government agency enacted March 3, 1865. The purpose of this organization was to aid and protect the newly freed slaves in the south after the Civil War. This was a very influential agency and some people would find it to be a major influence in the life of newly freed slaves. In this paper I will explain to you the purpose, the events that led up to the Freedmen’s Bureau, and the people that influenced the Freedmen’s Bureau. The purpose of the bureau was to provide food and medical care to the freedmen of the south. This bureau was only supposed to be in effect for one year; however, congress extended it contrary to the veto Andrew Johnson. In addition to providing food and medical care to the freedmen of the south; the bureau also helped to manage abandon property, establish schools, and regulate labor. The bureau was successful in educating the freedmen, but was very unsuccessful in establishing land. It was very hard for the newly freed slaves to own land or anything for that manner and it took a very long time to establish anything major for them. Later on after the act was established the freedmen were granted 85,000 acres of land but President Andrew Johnson revoked the land and gave it to the Confederate landowners. After the land was revoked the bureau focused on employment for the freedmen. They were able to acquire employment working on plantations; however, this became a problem when they became sharecroppers and tenant farmers. The bureau had many problems but all in all they did work hard to help the newly freed slaves establish the rights that they weren’t able to obtain. The freedmen’s bureau was established on the sympathy of a Civil War hero. He felt sorry for the blacks that had to transition from captivity to freedom so suddenly. After President Johnson unconstitutionally vetoed the bill, congress passed the bill over his veto. Whites in the south were opposed to African Americans having rights, and the bureau didn’t have the proper military force in place to establish any authority. Eventually the military had the move to the western frontier. The bureau’s work stemmed the establishment of the government involving themselves with social welfare and labor relations. I will now explain the people that played a significant role in influencing and implementing the freedmen’s bureau. The freedmen’s bureau was initiated by former President Abraham Lincoln. It was also headed by Union Army General Oliver O. Howard. George Ruby was an African American teacher and administrator that was the bureau’s inspector. He helped to establish school for African Americans and he also inspected the field officer’s that worked within the bureau. Unfortunately under the leadership of President Ulysses S. Grant, the bureau was disbanded. According to history the freedmen’s bureau was not very successful. Out of all of the promises that were made to the newly freed African Americans, very few were kept. Essentially they were left to fend for themselves. Promises such as employment and some education were kept. The promises for land and racial equality were not kept and this enraged the supporters of the bureau and the African Americans themselves. If the bureau would have had the proper financial backing and the proper number of staff it probably would have been very successful. Being that the bureau let the freedmen down by not providing the necessary funds, land, and education they lost faith in the United States government. The bureau has been labeled a failure by historians. In essence the Freedmen’s Bureau was a relief organization set in place to help freedmen transition from slavery to the free world. Many promises such as land, employment, racial equality, and education were promised; but very few promises were kept. The bureau was underfunded and undermanned and the necessary resources hadn’t been set in place for it to thrive like it was supposed to.

Abraham Lincoln and the Telegraph

Abraham Lincoln and the Telegraph President Abraham Lincoln used the telegraph extensively during the Civil War, and was known to spend many hours in a small telegraph office set up in the War Department building near the White House. Lincolns telegrams to generals in the field were a turning point in military history, as they marked the first time a commander in chief could communicate, practically in real time, with his commanders. And as Lincoln was always a skillful politician, he recognized the great value of the telegraph in spreading information from the army in the field to the public in the North. In at least one instance, Lincoln personally interceded to make sure a newspaperman had access to telegraph lines so a dispatch about action in Virginia could appear in the New York Tribune. Besides having an immediate influence on the actions of the Union Army, the telegrams sent by Lincoln also provide a fascinating record of his wartime leadership. The texts of his telegrams, some of which he wrote out for the transmitting clerks, still exist in the National Archives and have been used by researchers and historians. Lincoln's Interest in Techology Lincoln was self-educated and always highly inquisitive, and, like many people of his era, he had a keen interest in emerging technology. He followed the news of new inventions. And he was the only American president to obtain a patent, for a device he designed to assist riverboats to cross sandbars. When the telegraph changed communication in America in the 1840s, Lincoln would certainly have read about those advances. Its likely he knew about the wonders of the telegraph from newspaper articles he read in Illinois before any telegraph wires had reached that far west. When the telegraph started to become common through the settled parts of the nation, including his native Illinois, Lincoln would have had some contact with the technology. As a lawyer working for railroad companies, Lincoln would have been a sender and receiver of telegraph messages. One of the men who would serve as a government telegraph operator during the Civil War, Charles Tinker, had done the same job in civilian life at  a hotel in Pekin, Illinois. He later recalled that in the spring of 1857 he chanced to meet  Lincoln, who was in town on business related to his legal practice. Tinker recalled that Lincoln had watched him sending messages by tapping the telegraph key and writing down incoming messages he converted from Morse code. Lincoln asked him to explain how the apparatus worked. Tinker recalled going into considerable detail, describing even the batteries and electrical coils as Lincoln listened intently. During the campaign of 1860, Lincoln learned he had won the Republican nomination and later the presidency via telegraph messages which arrived in his hometown of Springfield, Illinois. So by the time he moved to Washington to take up residence in the White House he was not only aware of how the telegraph worked, but he recognized its great usefulness as a communication tool. The Military Telegraph System Four telegraph operators were recruited for government service in late April 1861, soon after the attack on Fort Sumter. The men had been employees of the Pennsylvania Railroad, and were enlisted because Andrew Carnegie, the future industrialist, was an executive of the railroad who had been pressed into government service and ordered to create a military telegraph network. One of the young telegraph operators, David Homer Bates, wrote a fascinating memoir, Lincoln In the Telegraph Office, decades later. Lincoln In the Telegraph Office For the first year of the Civil War, Lincoln was barely involved with the militarys telegraph office. But in the late spring of 1862 he began to use the telegraph to give orders to his officers. The Army of the Potomac was becoming bogged down during General George McClellans Peninsula Campaign in Virginia, Lincolns frustration with his commander may have moved him to establish faster communication with the front. During the summer of 1862 Lincoln took up the habit he followed for the rest of the war: he would often visit the War Department telegraph office, spending long hours sending dispatches and waiting for responses. Lincoln developed a warm rapport with the young telegraph operators. And he found the telegraph office a useful retreat from the much busier White House. One of his constant complaints about the White House was that job seekers and various political figures wanting favors would descend upon him. In the telegraph office he could hide away and concentrate on the serious business of conducting the war. According to David Homer Bates, Lincoln wrote the original draft of the Emancipation Proclamation at a desk in the telegraph office in 1862. The relatively secluded space gave him solitude to gather his thoughts. He would spend entire afternoons drafting one of  the most historic documents of his presidency. The Telegraph Influenced Lincoln's Style of Command While Lincoln was able to communicate fairly quickly with his generals, his use of communication was not always a happy experience. He began to feel that General George McClellan was not always being open and honest with him. And the nature of McClellans telegrams may have led to the crisis of confidence that led Lincoln to relieve him of command following the Battle of Antietam. By contrast, Lincoln seemed to have a good rapport via telegram with General Ulysses S. Grant. Once Grant was in command of the army, Lincoln communicated with him extensively via telegraph. Lincoln trusted Grants messages, and he found that orders sent to Grant were followed. The Civil War had to be won, of course, on the battlefield. But the telegraph, especially the way it was used by President Lincoln, did have an effect on the outcome.

Ideally, discharge planning should begin soon after the clients admission to the health care facility. The purpose of discharge planning process is to assist the client to make a smooth transition from one setting or level of care to another without impending the already achieved progress. Discharge planning is directed towards teaching the client and significant others about the condition and its effects on lifestyle, providing instructions for performing self-care activities, informing the client of any dietary or activity restrictions, and arranging for any follow-up care that may be necessary (Funnell Koutoukidis, 2008).

Literature course - Essay Example Why are we joking about this? It is taking away from everything we are striving for. Why is it that the media, especially television, still picture women as cooks, cleaners, housekeepers and filling gender-specific roles. This disturbs me no end. I thought all along that we were trying to be a more open-minded society where women are known to be strong, able to occupy powerful positions and at times be even superior to men. (example of irony) We must never underestimate women. Remember Joan of Arc and how she led the French army in the war against the English and winning? Wasn’t it a woman- Cleopatra and not a pharaoh who ruled Egypt successfully for a time until the snake was her undoing? And today, we have women invading areas of human endeavor where men heretofore held sway. Most modern families have mothers who are both housekeepers and breadwinners at the same time. We now have women astronauts, company CEO’s, doctors, professors, etc. In American politics, Nancy Pelosi heads the House of Representatives, Condoleeza Rice is the U.S, roving ambassador and doing a wonderful job of mediating with the leaders of countries all over the world. And Hillary Clinton is running for the Presidency. Is America breeding a race of super-women? In the field of entertainment, both screen and stage, American actresses take the lead. In Religion, there are more nuns than priests; however, we still have to see the fairer sex wearing the Fisherman’s ring. (This is a metaphor wherein there is reference to St. Peter, the first Pope, the first one to wear the Fisherman’s ring.) There are still things which women can do better than the men and other things which only women can do and no man can. God meant for women to conceive, carry babies in their wombs and give birth. Then they create a loving and nurturing environment for the children and teach them proper

Summary - Essay Example It was assumed that there was lack of change in ideologies among the Justices. This conventional view is a result of empirical observation and intuition. One of the main challenges is the study done on voting of justices. In civil liberties, writers reached a conclusion that the rulings of seven Justices (Burton, Burger, Harlan, Brennan, Jackson, Stewart and Marshall) remained unchanged over the period of their careers. The others however, changed in significant ways. There was a great need to resolve the debate that had come up. There was need to reconsider the appointment of justices. In trending to the left, we consider Justice Blackmun, who was among the twelve Justices. He said that when Justices go on Supreme Court their constitutional philosophies are not fully developed. Douglas and Harlan moved to the right and later changed to the left. When appointing a justice, we should ensure that we share the same ideologies with him. Supreme court justices are assumed to have strong dependent votes basing on their personal policies and values. Herman Pritchett’s The Roosevelt Court (1948) examines dissents and voting blocks of Justices. The court allows Justices to be dependent because there is no electoral accountability and the idea that the Supreme Court gives the last and final ruling. Justices are believed to be granted independent powers so that their rulings and not influenced by other parties. Their rulings hence are considered fair and just. Perceived values are not regarded as perfect ideologies of Supreme Court justices. The dependence granted to justices, therefore, renders their voting behavior unpredictable. There is a high correlation between the justices’ votes in civil society and their ideological values. Here we consider how powers are separated in courts. We shall consider the attitudinal model and the model of separation of powers. In attitudinal model, judges make rulings basing on the facts of the
