French Chefs - Essay Example It is by her presence that the civilized dining experience was elevated in France, which gave a decisive influence on the future of its cuisine.2 This initial influence was seconded by the great strides of chef Francois de La Varenne in 1600s who created sauces that later became the basis of haute cuisine, a precise and skilled artistry. A five-volume publication of Marie Antoine Careme set the standards for classic French cooking in the early 1800s, which was later modernized and perfected by Georges Auguste Escoffier.3 Escoffier, with his creativity, came up with thousands of recipes and helped making known the French cuisine through his publication. At present, there are two prestigious cooking schools named after Varenne and Escoffier; namely, La Varenne in Burgundy and the Ritz-Escoffier Ecole de Gastronomie Francaise in Paris, respectively.4 Currently, France consists of as many as thirty different food regions, which is partially caused by geographical diversification. Italy lies to the southeast of France, from where Catherine de Medici originated and to which Provencal cuisine has strong ties. To the southwest, Basques cooking emerged as a wonderful fusion of French and Spanish cuisines. In the northern regions of France emerged Belgium influences to the French cuisine, fitting the exceptional taste of people in this region. Meanwhile, Alsacian food prevails in the northeast, apparently with German influences. The position of Switzerland in the east made French countryside become best known for its cheese specialties, while southern French food across the Mediterranean exhibits North African influences of the French cuisine. All these influences demonstrate the geographical factors leading to a country to develop distinct regional cuisines in several of its regions. The rich history of France in terms of development of its cuisines alongside the flexibility of its people in various regions to integrate French cuisines with neighboring those of countries are sufficient to conclude that in terms of this historical criterion, the French chefs are better than other chefs in the world. Creativity French cuisine is highly creative, and this creativity has been what it is known for. The dishes trout amandine, lobster brisque and chateaubriand are served in a casual, yet elegant manner, as well as a perfectly roasted rack of lamb with side tripping presented creatively to suit the savory taste of the diner.5 Varying food textures and colors are employed in creative and beautiful presentations, which are emphasized in the French cuisine. French cuisines normally follow a standard, on which this creativity is based. To demonstrate, a French lentil salad is given a new twist by eschewing chervil for minced fresh cilantro, with a bit of soy sauce and fresh fava beans for contrast,6 emphasizing color and design. French's standards for creativity of presentation make its chefs constantly aware of the rules in cuisine

Augmented Reality Ar Is A Live Media Essay

Augmented Reality Ar Is A Live Media Essay Hardware components for augmented reality are: processor, display, sensors and input devices. Modern mobile computing devices like smartphones and tablet computers contain these elements which often include a camera and MEMS sensors such as accelerometer, GPS, and solid state compass, making them suitable AR platforms.[8] [edit] Display Various technologies are used in Augmented Reality rendering including optical projection systems, monitors, hand held devices, and display systems worn on ones person. [edit] Head-mounted A head-mounted display (HMD) is a display device paired to a headset such as a harness or helmet. HMDs place images of both the physical world and virtual objects over the users field of view. Modern HMDs often employ sensors for six degrees of freedom monitoring that allow the system to align virtual information to the physical world and adjust accordingly with the users head movements.[9][10][11] HMDs can provide users immersive, mobile and collaborative AR experiences.[12] [edit] Eyeglasses AR displays can be rendered on devices resembling eyeglasses. Versions include eye wear that employ cameras to intercept the real world view and re-display its augmented view through the eye pieces[13] and devices in which the AR imagery is projected through or reflected off the surfaces of the eye wear lens pieces.[14][15][16] [edit] Contact lenses Contact lenses that display AR imaging are in development. These bionic contact lenses might contain the elements for display embedded into the lens including integrated circuitry, LEDs and an antenna for wireless communication.[17][18][19][20] Another version of contact lenses, in development for the U.S. Military, is designed to function with AR spectacles, allowing soldiers to focus on close-to-the-eye AR images on the spectacles and distant real world objects at the same time.[21][22] [edit] Virtual retinal display A virtual retinal display (VRD) is a personal display device under development at the University of Washingtons Human Interface Technology Laboratory. With this technology, a display is scanned directly onto the retina of a viewers eye. The viewer sees what appears to be a conventional display floating in space in front of them.[23] [edit] EyeTap The EyeTap (also known as Generation-2 Glass[24]) captures rays of light that would otherwise pass through the center of a lens of an eye of the wearer, and substituted each ray of light for synthetic computer-controlled light. The Generation-4 Glass[24] (Laser EyeTap) is similar to the VRD (i.e. it uses a computer controlled laser light source) except that it also has infinite depth of focus and causes the eye itself to, in effect, function as both a camera and a display, by way of exact alignment with the eye, and resynthesis (in laser light) of rays of light entering the eye.[25] [edit] Handheld Handheld displays employ a small display that fits in a users hand. All handheld AR solutions to date opt for video see-through. Initially handheld AR employed fiduciary markers,[26] and later GPS units and MEMS sensors such as digital compasses and six degrees of freedomaccelerometer-gyroscope. Today SLAM markerless trackers such as PTAM are starting to come into use. Handheld display AR promises to be the first commercial success for AR technologies. The two main advantages of handheld AR is the portable nature of handheld devices and ubiquitous nature of camera phones. The disadvantages are the physical constraints of the user having to hold the handheld device out in front of them at all times as well as distorting effect of classically wide-angled mobile phone cameras when compared to the real world as viewed through the eye.[27] [edit] Spatial Spatial Augmented Reality (SAR) augments real world objects and scenes without the use of special displays such as monitors, head mounted displays or hand-held devices. SAR makes use of digital projectors to display graphical information onto physical objects. The key difference in SAR is that the display is separated from the users of the system. Because the displays are not associated with each user, SAR scales naturally up to groups of users, thus allowing for collocated collaboration between users. SAR has several advantages over traditional head-mounted displays and handheld devices. The user is not required to carry equipment or wear the display over their eyes. This makes spatial AR a good candidate for collaborative work, as the users can see each others faces. A system can be used by multiple people at the same time without each having to wear a head-mounted display. Examples include shader lamps, mobile projectors, virtual tables, and smart projectors. Shader lamps mimic and augment reality by projecting imagery onto neutral objects, providing the opportunity to enhance the objects appearance with materials of a simple unit- a projector, camera, and sensor. Handheld projectors further this goal by enabling cluster configurations of environment sensing, reducing the need for additional peripheral sensing.[28][29] Other tangible applications include table and wall projections. One such innovation, the Extended Virtual Table, separates the virtual from the real by including beam-splitter mirrors attached to the ceiling at an adjustable angle.[30] Virtual showcases, which employ beam-splitter mirrors together with multiple graphics displays, provide an interactive means of simultaneously engaging with the virtual and the real.[31][32] Altogether, current augmented reality display technology can be applied to improve design and visualization, or function as scientific simulations and tools for education or entertainment. Many more implementations and configurations make spatial augmented reality display an increasingly attractive interactive alternative.[11] Spatial AR does not suffer from the limited display resolution of current head-mounted displays and portable devices. A projector based display system can simply incorporate more projectors to expand the display area. Where portable devices have a small window into the world for drawing, a SAR system can display on any number of surfaces of an indoor setting at once. The drawbacks, however, are that SAR systems of projectors do not work so well in sunlight and also require a surface on which to project the computer-generated graphics. Augmentations cannot simply hang in the air as they do with handheld and HMD-based AR. The tangible nature of SAR, though, makes this an ideal technology to support design, as SAR supports both a graphical visualisation and passive haptic sensation for the end users. People are able to touch physical objects, and it is this process that provides the passive haptic sensation.[7][33][34][35] [edit] Tracking Modern mobile augmented reality systems use one or more of the following tracking technologies: digital cameras and/or other optical sensors, accelerometers, GPS, gyroscopes, solid state compasses, RFID and wireless sensors. These technologies offer varying levels of accuracy and precision. Most important is the position and orientation of the users head. Tracking the users hand(s) or a handheld input device can provide a 6DOF interaction technique.[36] [edit] Input devices Techniques include speech recognition systems that translate a users spoken words into computer instructions and gesture recognition systems that can interpret a users body movements by visual detection or from sensors embedded in a peripheral device such as a wand, stylus, pointer, glove or other body wear.[37][38][39][40] [edit] Computer The computer analyzes the sensed visual and other data to synthesize and position augmentations. [edit] Software and algorithms A key measure of AR systems is how realistically they integrate augmentations with the real world. The software must derive real world coordinates, independent from the camera, from camera images. That process is called image registration which uses different methods of computer vision, mostly related to video tracking.[41][42] Many computer vision methods of augmented reality are inherited from visual odometry. Usually those methods consist of two parts. First detect interest points, or fiduciary markers, or optical flow in the camera images. First stage can use feature detection methods like corner detection, blob detection, edge detection or thresholding and/or other image processing methods.[43][44] The second stage restores a real world coordinate system from the data obtained in the first stage. Some methods assume objects with known geometry (or fiduciary markers) present in the scene. In some of those cases the scene 3D structure should be precalculated beforehand. If part of the scene is unknown simultaneous localization and mapping (SLAM) can map relative positions. If no information about scene geometry is available, structure from motion methods like bundle adjustment are used. Mathematical methods used in the second stage include projective (epipolar) geometry, geometric algebra, rotation representation with exponential map, kalman and particle filters, nonlinear optimization, robust statistics. [edit] Applications Augmented reality has many applications, and many areas can benefit from the usage of AR technology. AR was initially used for military, industrial, and medical applications, but was soon applied to commercial and entertainment areas as well.[45] [edit] Archaeology AR can be used to aid archaeological research, by augmenting archaeological features onto the modern landscape, enabling archaeologists to formulate conclusions about site placement and configuration.[46] Another application given to AR in this field is the possibility for users to rebuild ruins, buildings, or even landscapes as they formerly existed.[47] [edit] Architecture AR can aid in visualizing building projects. Computer-generated images of a structure can be superimposed into a real life local view of a property before the physical building is constructed there. AR can also be employed within an architects work space, rendering into their view animated 3D visualizations of their 2D drawings. Architecture sight-seeing can be enhanced with AR applications allowing users viewing a buildings exterior to virtually see through its walls, viewing its interior objects and layout.[48][49] [edit] Art AR technology has helped disabled individuals create art by using eye tracking to translate a users eye movements into drawings on a screen.[50] An item such as a commemorative coin can be designed so that when scanned by an AR-enabled device it displays additional objects and layers of information that were not visible in a real world view of it.[51][52] [edit] Commerce ViewAR BUTLERS App Placing furniture using AR AR can enhance product previews such as allowing a customer to view whats inside a products packaging without opening it.[53] AR can also be used as an aid in selecting products from a catalog or through a kiosk. Scanned images of products can activate views of additional content such as customization options and additional images of the product in its use.[54][55] AR is used to integrate print and video marketing. Printed marketing material can be designed with certain trigger images that, when scanned by an AR enabled device using image recognition, activate a video version of the promotional material.[56][57][58] [edit] Education Augmented reality applications can complement a standard curriculum. Text, graphics, video and audio can be superimposed into a students real time environment. Textbooks, flashcards and other educational reading material can contain embedded markers that, when scanned by an AR device, produce supplementary information to the student rendered in a multimedia format.[59][60][61] Students can participate interactively with computer generated simulations of historical events, exploring and learning details of each significant area of the event site.[62] AR can aide students in understanding chemistry by allowing them to visualize the spatial structure of a molecule and interact with a virtual model of it that appears, in a camera image, positioned at a marker held in their hand.[63] Augmented reality technology also permits learning via remote collaboration, in which students and instructors not at the same physical location can share a common virtual learning environment populated by vi rtual objects and learning materials and interact with another within that setting.[64] [edit] Everyday 30 years of Augmediated Reality in everyday life. Since the 1970s and early 1980s, Steve Mann has been developing technologies meant for everyday use i.e. horizontal across all applications rather than a specific vertical market. Examples include Manns EyeTap Digital Eye Glass, a general-purpose seeing aid that does dynamic-range management (HDR vision) and overlays, underlays, simultaneous augmentation and diminishment (e.g. diminishing the electric arc while looking at a welding torch).[65] [edit] Industrial design AR can help industrial designers experience a products design and operation before completion. Volkswagen uses AR for comparing calculated and actual crash test imagery.[66] AR can be used to visualize and modify a car body structure and engine layout. AR can also be used to compare digital mock-ups with physical mock-ups for efficiently finding discrepancies between them.[67][68] [edit] Medical Augmented Reality can provide the surgeon with information, which are otherwise hidden, such as showing the heartbeat rate, the blood pressure, the state of the patients organ, etc. In particular AR can be used to let the doctor look inside the patient by combining one source of images such as an X-ray with another such as video. This helps the doctor to identify the problem with the patient in a more intuitive way than looking at only type of image data. This approach works in a similar as the technicians doing maintenance work. Examples include a virtual X-ray view based on prior tomography or on real time images from ultrasound and confocal microscopy probes[69] or visualizing the position of a tumor in the video of an endoscope.[70] AR can enhance viewing a fetus inside a mothers womb.[71] See also Mixed reality. [edit] Military In combat, AR can serve as a networked communication system that renders useful battlefield data onto a soldiers goggles in real time. From the soldiers viewpoint, people and various objects can be marked with special indicators to warn of potential dangers. Virtual maps and 360Â ° view camera imaging can also be rendered to aid a soldiers navigation and battlefield perspective, and this can be transmitted to military leaders at a remote command center.[72] [edit] Navigation Augmented reality map on iPhone AR can augment the effectiveness of navigation devices. Information can be displayed on an automobiles windshield indicating destination directions and meter, weather, terrain, road conditions and traffic information as well as alerts to potential hazards in their path.[73][74][75] Aboard maritime vessels, AR can allow bridge watch-standers to continuously monitor important information such as a ships heading and speed while moving throughout the bridge or performing other tasks.[76] [edit] Office workplace AR can help facilitate collaboration among distributed team members in a work force via conferences with real and virtual participants. AR tasks can include brainstorming and discussion meetings utilizing common visualization via touch screen tables, interactive digital whiteboards, shared design spaces, and distributed control rooms.[77][78][79] [edit] Sports and entertainment AR has become common in sports telecasting. Sports and entertainment venues are provided with see-through and overlay augmentation through tracked camera feeds for enhanced viewing by the audience. Examples include the yellow first down line seen in television broadcasts of American football games showing the line the offensive team must cross to receive a first down. AR is also used in association with football and other sporting events to show commercial advertisements overlaid onto the view of the playing area. Sections of rugby fields and cricket pitches also display sponsored images. Swimming telecasts often add a line across the lanes to indicate the position of the current record holder as a race proceeds to allow viewers to compare the current race to the best performance. Other examples include hockey puck tracking and annotations of racing car performance and snooker ball trajectories. [41][80] AR can enhance concert and theater performances. For example, artists can allow listeners to augment their listening experience by adding their performance to that of other bands/groups of users.[81][82][83] The gaming industry has benefited a lot from the development of this technology. A number of games have been developed for prepared indoor environments. Early AR games also include AR air hockey, collaborative combat against virtual enemies, and an AR-enhanced pool games. A significant number of games incorporate AR in them and the introduction of the smartphone has made a bigger impact.[84][85] [edit] Task support Complex tasks such as assembly, maintenance, and surgery can be simplified by inserting additional information into the field of view. For example, labels can be displayed on parts of a system to clarify operating instructions for a mechanic who is performing maintenance on the system.[86][87] Assembly lines gain many benefits from the usage of AR. In addition to Boeing, BMW and Volkswagen are known for incorporating this technology in their assembly line to improve their manufacturing and assembly processes.[88][89][90] Big machines are difficult to maintain because of the multiple layers or structures they have. With the use of AR the workers can complete their job in a much easier way because AR permits them to look through the machine as if it was with x-ray, pointing them to the problem right away.[91] [edit] Tourism and sightseeing Augmented reality applications can enhance a users experience when traveling by providing real time informational displays regarding a location and its features, including comments made by previous visitors of the site. AR applications allow tourists to experience simulations of historical events, places and objects by rendering them into their current view of a landscape.[92][93][94] AR applications can also present location information by audio, announcing features of interest at a particular site as they become visible to the user.[95][96] [edit] Translation AR systems can interpret foreign text on signs and menus and, in a users augmented view, re-display the text in the users language. Spoken words of a foreign language can be translated and displayed in a users view as printed subtitles How Augmented Reality Works Video games have been entertaining us for nearly 30 years, ever since Pong was introduced to arcades in the early 1970s. Computer graphics have become much more sophisticated since then, and game graphics are pushing the barriers of photorealism. Now, researchers and engineers are pulling graphics out of your television screen or computer display and integrating them into real-world environments. This new technology, called augmented reality, blurs the line between whats real and whats computer-generated by enhancing what we see, hear, feel and smell. On the spectrum between virtual reality, which creates immersive, computer-generated environments, and the real world, augmented reality is closer to the real world. Augmented reality adds graphics, sounds, haptic feedback and smell to the natural world as it exists. Both video games and cell phones are driving the development of augmented reality. Everyone from tourists, to soldiers, to someone looking for the closest subway stop can now benefit from the ability to place computer-generated graphics in their field of vision. Augmented reality is changing the way we view the world or at least the way its users see the world. Picture yourself walking or driving down the street. With augmented-reality displays, which will eventually look much like a normal pair of glasses, informative graphics will appear in your field of view, and audio will coincide with whatever you see. These enhancements will be refreshed continually to reflect the movements of your head. Similar devices and applications already exist, particularly on smartphones like the iPhone. In this article, well take a look at where augmented reality is now and where it may be headed soon. Augmenting Our World The basic idea of augmented reality is to superimpose graphics, audio and other sensory enhancements over a real-world environment in real time. Sounds pretty simple. Besides, havent television networks been doing that with graphics for decades? However, augmented reality is more advanced than any technology youve seen in television broadcasts, although some new TV effects come close, such as RACEf/x and the super-imposed first down line on televised U.S. football games, both created by Sportvision. But these systems display graphics for only one point of view. Next-generation augmented-reality systems will display graphics for each viewers perspective. Some of the most exciting augmented-reality work is taking place in research labs at universities around the world. In February 2009, at the TED conference, Pattie Maes and Pranav Mistry presented their augmented-reality system, which they developed as part of MIT Media Labs Fluid Interfaces Group. They call it SixthSense, and it relies on some basic components that are found in many augmented reality systems: Camera Small projector Smartphone Mirror These components are strung together in a lanyardlike apparatus that the user wears around his neck. The user also wears four colored caps on the fingers, and these caps are used to manipulate the images that the projector emits. SixthSense is remarkable because it uses these simple, off-the-shelf components that cost around $350. It is also notable because the projector essentially turns any surface into an interactive screen. Essentially, the device works by using the camera and mirror to examine the surrounding world, feeding that image to the phone (which processes the image, gathers GPS coordinates and pulls data from the Internet), and then projecting information from the projector onto the surface in front of the user, whether its a wrist, a wall, or even a person. Because the user is wearing the camera on his chest, SixthSense will augment whatever he looks at; for example, if he picks up a can of soup in a grocery store, SixthSense can find and project onto the soup information about its ingredients, price, nutritional value even customer reviews. By using his capped fingers Pattie Maes says even fingers with different colors of nail polish would work a user can perform actions on the projected information, which are then picked up by the camera and processed by the phone. If he wants to know more about that can of soup than is projected on it, he can use his fingers to interact with the projected image and learn about, say, competing brands. SixthSense can also recognize complex gestures draw a circle on your wrist and SixthSense projects a watch with the current time. Mistry demonstrates SixthSense Photo courtesy Sam Ogden, Pranav Mistry, MIT Media Lab The SixthSense augmented reality system lets you project a phone pad onto your hand and phone a friend without removing the phone from your pocket. See more gadget pictures. Photo courtesy Lynn Barry, Pranav Mistry, MIT Media Lab Augmented Reality on Cell Phones While it may be some time before you buy a device like SixthSense, more primitive versions of augmented reality are already here on some cell phones, particularly in applications for the iPhone and phones with the Android operating system. In the Netherlands, cell phone owners can download an application called Layar that uses the phones camera and GPS capabilities to gather information about the surrounding area. Layar then shows information about restaurants or other sites in the area, overlaying this information on the phones screen. You can even point the phone at a building, and Layar will tell you if any companies in that building are hiring, or it might be able to find photos of the building on Flickr or to locate its history on Wikipedia. Layar isnt the only application of its type. In August 2009, some iPhone users were surprised to find an augmented-reality easter egg hidden within the Yelp application. Yelp is known for its user reviews of restaurants and other businesses, but its hidden augmented-reality component, called Monocle, takes things one step further. Just start up the Yelp app, shake your iPhone 3GS three times and Monocle activates. Using your phones GPS and compass, Monocle will display information about local restaurants, including ratings and reviews, on your cell phone screen. You can touch one of the listings to find out more about a particular restaurant. There are other augmented reality apps out there for the iPhone and other similar phones and many more in development. Urbanspoon has much of the same functionality as Yelps Monocle. Then theres Wikitude, which finds information from Wikipedia about sites in the area. Underlying most of these applications are a phones GPS and compass; by knowing where you are, these applications can make sure to offer information relevant to you. Were still not quite at the stage of full-on image recognition, but trust us, people are working on it. Weve looked at some of the existing forms of augmented reality. On the next page, well examine some of the other applications of the technology, such as in video games and military hardware An iPhone user displays the augmented reality app Monocle, which combines the phones camera view with tiny tags indicating the names, distances and user ratings of nearby bars, restaurants and more. AP Photo/Marcio Jose Sanchez Augmented Reality in Video Games and the Military Video game companies are quickly hopping aboard the augmented-reality locomotive. A company called Total Immersion makes software that applies augmented reality to baseball cards. Simply go online, download the Total Immersion software and then hold up your baseball card to a webcam. The software recognizes the card (and the player on it) and then displays related video on your computer screen. Move the card in your hands make sure to keep it in view of the camera and the 3-D figure on your screen will perform actions, such as throwing a ball at a target. Total Immersions efforts are just the beginning. In the next couple of years, well see games that take augmented reality out into the streets. Consider a scavenger-hunt game that uses virtual objects. You could use your phone to place tokens around town, and participants would then use their phones (or augmented-reality enabled goggles) to find these invisible objects. Demos of many games of this order already exist. Theres a human Pac-Man game that allows users to chase after each other in real life while wearing goggles that make them look like characters in Pac-Man. Arcane Technologies, a Canadian company, has sold augmented-reality devices to the U.S. military. The company produces a head-mounted display the sort of device that was supposed to bring us virtual reality that superimposes information on your world. Consider a squad of soldiers in Afghanistan, performing reconnaissance on an opposition hideout. An AR-enabled head-mounted display could overlay blueprints or a view from a satellite or overheard drone directly onto the soldiers field of vision. Now that weve established some of the many current and burgeoning uses of augmented reality, lets take a look at the technologys limitations and what the future holds. Augmented reality can breathe a little life into your sports trading cards. Photo courtesy Total Immersion Limitations and the Future of Augmented Reality Augmented reality still has some challenges to overcome. For example, GPS is only accurate to within 30 feet (9 meters) and doesnt work as well indoors, although improved image recognition technology may be able to help [source: Metz]. People may not want to rely on their cell phones, which have small screens on which to superimpose information. For that reason, wearable devices like SixthSense or augmented-reality capable contact lenses and glasses will provide users with more convenient, expansive views of the world around them. Screen real estate will no longer be an issue. In the near future, you may be able to play a real-time strategy game on your computer, or you can invite a friend over, put on your AR glasses, and play on the tabletop in front of you. There is such a thing as too much information. Just as the CrackBerry phenomenon and Internet addiction are concerns, an overreliance on augmented reality could mean that people are missing out on whats right in front of them. Some people may prefer to use their AR iPhone applications rather than an experienced tour guide, even though a tour guide may be able to offer a level of interaction, an experience and a personal touch unavailable in a computer program. And there are times when a real plaque on a building is preferable to a virtual one, which would be accessible only by people with certain technologies. There are also privacy concerns. Image-recognition software coupled with AR will, quite soon, allow us to point our phones at people, even strangers, and instantly see information from their Facebook, Twitter, Amazon, LinkedIn or other online profiles. With most of these services people willingly put information about themselves online, but it may be an unwelcome shock to meet someone, only to have him instantly know so much about your life and background. Despite these concerns, imagine the possibilities: you may learn things about the city youve lived in for years just by pointing your AR-enabled phone at a nearby park or building. If you work in construction, you can save on materials by using virtual markers to designate where a beam should go or which structural support to inspect. Paleontologists working in shifts to assemble a dinosaur skeleton could leave virtual notes to team members on the bones themselves, artists could produce virtual graffiti and doctors could overlay a digital image of a patients X-rays onto a mannequin for added realism. The future of augmented reality is clearly bright, even as it already has found its way into our cell phones and video game systems. For more information about the subject and where its headed, take a look at the links on the next page Augmented Reality Augmented reality (AR) is a live, direct or indirect, view of a physical, real-world environment whose elements are augmented by computer-gener

The Adventures of Tom Sawyer - Truth and Tom Sawyer :: The Adventures of Tom Sawyer

The Adventures of Tom Sawyer - Truth and Tom Sawyer    â€Å"The road to truth is long, and lined the whole way with annoying bastards.† Alexander Jablokov The Adventures of Tom Sawyer, by Mark Twain, has many themes; one theme is the importance of truth in society.   A Society is inevitable. It will always be there as a pleasure and a burden. Society expects, or perhaps demands, certain behavior from the individual.   If one wishes to enjoy the pleasures of society then one must play by society’s rules.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Tom Sawyer, THE MAIN CHARACTER, is an imaginative young man who sometimes allows his imagination and high-spirit TO get in the way of telling the truth.  Ã‚   Tom is very adventurous; he never passes up a chance to play pirates, robbers, or soldiers. We are introduced to Tom, when he is climbing in his window after a long night of cavorting with his friends. Soon after this, Tom meets Huckleberry Fin. Huck is a social outcast who likes to live by his own terms.   Tom and Huck become good friends.   One night the two boys go to the graveyard AND while they are there they witness the murder of the town doctor, Mr. Robinson. The boys watched as Injun Joe kills the doctor and frames a drunk by the name of Muff Potter, who happens to be IN the wrong place at the wrong time. The boys swear never to speak of THE MURDER again. Later, Tom falls in love with his new neighbor, Becky Thatcher. Eventually the two become engaged, but the engagement falls through when Tom accidentally mentions his former love while talking with Becky. The two feud and do not speak. Meanwhile, the whole town is gossiping of the murder of Dr. Robinson and the prosecution of Muff Potter. A trail quickly forms and Muff is put on the stand.   Tom cannot allow the innocent Muff TO go to jail.   As the trial comes to a close, Tom testifies and indicates the guilt of Injun Joe.   When the trial ends, the manhunt for Injun Joe begins AND Tom is treated like a hero.Tom feels guilty knowing he broke a sacred oath with Huck. Becky and Tom soon become friends again after Tom takes Becky’s punishment at school for being careless with the teacher’s things.

Interpersonal Communication Com 200

Communication in Interpersonal Relationships Benjamin M. Phelps COM 200 Mrs. Joyce Walther October 4, 2010 Communication in Interpersonal Relationships Today many people still lack the ability to communicate effectively with in interpersonal relationships. It is through cooperation and collaboration that effective communication occurs. By analyzing and studying the communication process we can improve our ability to communicate effectively between one another. To have a successful interpersonal relationship one must first interact with others, which is called interpersonal communication (Hybels & Weaver, 2007).Recognizing emotions in other is a very important first step to building a relationship. If you can’t feel what someone else is feeling then you can’t connect with them on a personal level and that can hinder your relationship process. Interpersonal communication is important because of the functions it achieves. Whenever we engage in communication with anothe r person, we seek to gain information about them. We also give off information through a wide variety of verbal and non-verbal cues. Verbal communication has huge effects on many aspects of life, including interpersonal relationships.Speaking and telling our needs and wants verbally or non-verbally is a necessity for daily life. Verbal communication is organized by language; non-verbal communication is not. Most of us spend about 75 percent of our waking hours communicating our knowledge, thoughts, and ideas to others (Allis, 2002). However, most of us fail to realize that a great deal of our communication is of a non-verbal form as opposed to the oral and written forms. Non-verbal communication includes facial expressions, eye contact, tone of voice, body posture and motions, and positioning within groups.It may also include the way we wear our clothes or the silence we keep. In person-to-person communications our messages are sent on two levels simultaneously. If the nonverbal cue s and the spoken message are incongruous, the flow of communication is hindered. Right or wrong, the receiver of the communication tends to base the intentions of the sender on the non- verbal cues one receives. Before a person makes an attempt to form an interpersonal relationship they must decide what attracts them to that person.There are many factors that make up attraction to others. Physical attraction, perceived gain, similarities, differences, and proximity are some of them (Hybels, 2007). Most people are first attracted to others because of the way they look. Some people might have distinct characteristics that one might be attracted to such as; blues eyes, short hair, or even a small space between their teeth. If a person is not attracted to your appearance they are not likely to come up and carry on a conversation with you.For example, if an individual, who dislikes tattoos, is taking a class and has to choose a partner for a project, but there are only two people left an d one of them has tattoos he or she will mostly likely choose the individual without tattoos ,even    if the person with tattoos is a very intelligent individual. There are many cases where we are attracted to someone because of the perceived gain associated them for example, one might become friends with an employee at a restaurant in hope of having discounted meal when they eat there.The similarities and differences are a major factor in determining if the relationship will be right for you. Often we find ourselves attracted to people that share the same beliefs, values, and religion. Most people are also attracted to people who enjoy the same activities as they do. Contrary to the similarities people may also be attracted to the differences. For example, person who doesn’t like making decisions might be attracted to a strong decision maker.Because these characteristics complement each other, they might help strengthen the relationship (Hybels, 2007). Proximity is a valua ble factor also when it comes to evaluating the pros and cons of a relationship. Proximity is the close contact that occurs when people share an experience such as at work, school, or play (Hybels, 2007). If a person does not want to have a long distance romantic relationship and their partner moves away to attend college in another state, then it is most likely that the relationship will not last.Moving on to the next steps of forming an interpersonal relationship would be our motives for communicating. We are motivated to form relationships for many different reasons such as, pleasure, affection, inclusion, escape, relaxation, control and health (Hybels, 2007). If an individual is motivated by pleasure he or she might just want someone to go to the movies or discuss politics with. Maybe we might be motivated by affection; many people are looking for someone to give them attention; a â€Å"pat on the back† or a little kiss every now and then.Many marriages end in divorce bec ause of the lack of affection from their partner, but if they could have communicated effectively to each other that they needed more affection the relationship might not have ended. No matter what might motivate us, once we have started developing a relationship we have to decide how much of our selves we want to disclose to the relationship and at what point in the relationship. Self- disclosure is a process in which one person tells another person something he or she would not reveal to just anyone (Hybels, 2007).Self-disclosure is not simply providing information to another person. Instead, scholars define self-disclosure as sharing information with others that they would not normally know or discover (Borchers, 1999). Self-disclosure involves risk and vulnerability on the part of the person sharing the information. Self-disclosure performs many functions. It is also a way of gaining information about another person. We want to be able to predict the thoughts and actions of peop le we know. Self-disclosure is one way to learn about how another person thinks and feels.Once one person engages in self-disclosure, it is implied that the other person will also disclose personal information. Mutual disclosure deepens trust in the relationships and helps both people understand each other more. You also feel better about yourself and your relationship when the other person accepts what you tell them. While self disclosure can strengthen a relationship it can also damage it. A relationship can be damaged if the person you are pouring your soul out to do not like what they are hearing or if self-disclosure comes too early in a relationship it can be damaged.Thus, while self-disclosure is useful, it can also be damaging to a relationship. There are five different stages that we progress through while developing and strengthening our relationships, these are the â€Å"coming together† stages. No matter what type of relationship it is; romantic, platonic, or same gender relationship each kind still goes through each stages. The first stage is the initiating stage. The initiating stage is characterized by nervousness, caution, a bit of hesitation, and risk of being rejected (Hybels, 2007).Although one might proceed with caution, this stage can be very joyful experience and the outcomes can be great. Most people leave this stage with a new friend. The next stage is the experimenting stage. In this stage people make an effort to seek out common interest and experiences (Hybels, 2007). One might express a love for children and hopes of being a parent one day. This would be an important topic to discuss for a romantic relationship; each person needs to be aware of what the future might hold for them if they continue with the relationship.When experimenting with each other by discussing important topics and seeing the reactions of other, one can make a valid decision based on their knowledge of the other person to continue the relationship to the next stage. The intensifying stage is the third stage that we go through. Self-disclosure becomes more common in the intensifying stage. The relationship becomes less formal and statements are made about the level of commitment each has to the relationship. In this stage individuals might have nick names for one another or â€Å"inside jokes†.A statement about attending a vacation next summer in France is an example of the commitment one might have for the relationship. But while self-disclosure becomes more common and makes the relationship stronger it can also make the participants vulnerable to each other. The integrating stage is the fourth stage. This is the point where personalities are beginning to merge; people are expecting to see them together (Hybels, 2007). The individuals become a pair. They begin to do things together and, importantly, others come to see them as a pair.A shared relational identity also starts to form in this stage. By the end of this stage indi viduals should know how to communicate and responds with ease and understanding of the other person’s feelings. The final stage of coming together is the bonding stage. At this point, the participants make some sort of commitment that announces their relationship to those around them (Hybels, 2007). Two girls friends might say they are now â€Å"best friends† to announce their comment to their relationship or a couple might announce they are getting married or buying a house together.This stage involves a lot of commitment and dedication to the relationship and to each other. In all of the stages discussed we all have decision to make. We can either progress forward to the next stage, stay in the same stage we are in, move back a stage or exit the relationship all together. No matter what we as individuals choose to do we need to know how to communicate effectively to that next stage and we need to know how to handle conflict or resolve conflict in our relationships.We can do this by conflict resolution, which is negotiating to find a solution to the conflict (Hybels, 2007). Depending on how a conflict is resolved it can produce a positive or negative result. For example if two sisters are fight over a dress to wear on the weekend, they have two choices: one wear the dress and the other one does not, which leaves one sister unhappy (negative outcome) or neither of them wear it, so both are satisfied and neither of them are jealous of the other (positive outcome).It also helps to take a positive approach to conflict resolution, where discussion is considerate and non-confrontational, and the heart of the matter is on issues rather than on individuals. If this is done, then, as long as people listen carefully and explore facts, issues and possible solutions properly, conflict can often be resolved effectively. In short, interpersonal communication is just like any other works of life, it must be practiced and utilized regularly in order to be succe ssful. We must continually analyze and study it in order to improve our ability to communicate effectively in relationships.   That will lead to better relationships which lead to a better life, both personally and professionally.References Allis, R.

Things that affect the human body and attack its defence systems

There are many things that affect the human body and attack its defence systems,they can be naturally occouring in the environment or self inflicted or caused by societys pollution of our planet. Below are some conditions, with the effects that they cause to the human body and its defence mechanisms. Alcohol consumption is a health issue which affects the vast majority. A great many people drink alcohol regularly. Although they may not be alcoholic in the sense of being addicted to alcohol, they neverthelesss expose themselves to health risks. The alcohol in wines, beers and spirits is a depressant of the central nervous system. Small amounts gives a sense of well-being, with a realease from anxiety. However, this is accompanied by a fall-of in performance in any activity requiring skill. It also gives a misleading sense of confidence. The drunken driver usually thinks he or she is driving very well. Even a small amount of alcohol in the blood increases our reaction time. In some people, the reaction time is doubled even when the alcohol in the blood is well below the legal limit laid down for car drivers. This can make a big differenece in the time needed for a driver to apply the brakes after seeing a hazard. Read this Ch. 22 Respiratory System Alcohol reduces inhibitations and it can lead to irresponsible behaviour such as vandalism and aggression. Alcohol causes vaso-dilation in the skin, giving sense of warmth but in fact leading to a greater loss of body heat. A concentration of 500mg of alcohol in 100 cubic cm of blood results unconsciousness. More than this will kill, by stopping the action of the breathing centre in the brain. High doses of alcohol can harm virtually every organ in humans body. Many of these effects are reversible with abstinence, others are not. (2) Esophagus. Alcohol is associated with nearly half of the cancers of the esophagus, mouth, and larynx. Peole who vomit too intensely after getting drunk can cause tears in their esophagus. Brain. Alcohol depresses the central nervous system and contracts brain tissue. It destroys brain cells – which unlike many other types of cells in the body, do not regenerate. Taken in large amounts over a long period of time, alcohol can cause serious problems with cognition and memory. Heart. Heavy drinking can cause heart disease, stroke, high blood pressure and heart failure. Even social drinkers who binge on special occasions can sometimes get bouts of irregular heartbeats. Lungs. Heavy drinkers have more pulmonary infections and can be more susceptible to pneumonia and lung collapse. As intoxicated person loses his reflexses and can't clear his airway when he vomits. Stomach contents may get sucked into the lungs, which can lead to choking or pneumonia. Liver. Liver damage often begins with a fatty liver, and may progress to alcoholic hepatitis. That may be followed by the buidup of scar tissue known as cirrhosis. Cirrhosis can change the structure of the liver and choke off blood flow. This can cause varicose veins, which can rupture, triggering catastrophic bleeding. Stomach. Alcohol irritates the stomach, and can cause gastritis, ulcers and acid reflux. Gastritis is an inflamation of the mucous membrane that lines the stomach. Erosion in that lining can cause constant oozing of blood into the stomach or, if a vessel ruptures, major bleeding. Kidneys. Alcohol is a diuretic that increases urine output. Prolonged heavy drinking can cause kidney failure. Small intestines ; pancreas. Alcohol blocks the absorption and breakdown of nutrients by damaging the cells lining the stomach and intestines, and by decreasing the amount of digestive enzymes secreted by the pancreas. The pancreas can become inflamed and leak digestive enzymes, which then attackthe pancreas itself. Reproductive system. In men, it impairs the production of sperm and testosterone, and can lead to interfility and impotance. In women, the effect can be decreased estrogen metabolism in the liver which increases the amount of estrogen circulating the body, which can contribute to menstrual irregularities and even interfility. Blood. Prolonged alcohol abuse can cause anemias and abnormal blood clotting, which results in excessive bleeding and easy bruising. It also impairs the functionof white blood cells, increasing susceptibility to infection. Joints ; muscles. Alcohol dependence can cause osteoporosis ; arthritis, and deform the joints. It can atrphy muscles and cause acute muscle pain and weakness. Skin. Alcohol causes the small blood vessels in the skin to dilate(open), which results in a rush of warm blood to the surface. This makes the skin look flushed and gives the person a false feeling of â€Å"being hot†. (13) Heavy drinking during pregnancy can lead to deformed babies. Alcohol can cross the placenta and damage the foetus. Pregnant women who take as little as one alcoholic drink a day are at risk of having babies with lower than average birth weights. These under-weight babies are more likely to become ill. All levels of drinking are thought to increase the risk of miscariage. (1) The affects of alcohol vary with different people. Alcohol is a drug and must be handled with care. Knowing its uses and abuses is just imporatnt as reading the instructions on a bottle of pills. It is basic preventive medicine to know how your body handlers alcohol, how much is safe to drink, and, finally, how your body gets rid of it. When people drink small of alcohol enters directly into bloodstream through the lining of the mouth and throat. The remaining amount of alcohol is absorbed by the stomach or intestine. At this point the alcohol is then dispersed uniformly throughout the body. Its effects are similar to ether or chloroform, affecting all part of the body controlled by the brain. The ability to make appropriate judgements and to exercise self-control is affected. Alcohol must be broken down in order to leave the system. More than 90 percent of the alcohol is oxidized in the liver and the remainder is discharged through the lungs and kidneys. It takes just as long for the experienced drinker to eliminate alcohol as it does for the inexperienced drinker. (15) Ultraviolet light is a part of the light spectrum that is invisible to the human eye. Part of sunlight is UV light, which creates warmth, light, photosynthesis in plants, and vitamin D synthesis in the body. The sun produces about three types of UV lights: UVA, UVB, UVC. The ozone layer filters out UVC. UVA, however, has a long wavelenght light, so a certain amount reaches the earth's surface. UVA is the predominant light to reach earth. UVA causes damage to cellular membranes and DNA, and has been implicated in ageing of the skin and the development of skin cancer. Scientists believe it is UVB lights that are the paramount cause of premature ageing of skin, sunburn, skin cancers and other skin problems, despite the fact that UVB lights constitute for only 1% of UV lights that reach our skin. (4) UV light is beneficial for people and essential in the production of vitamin D, which is absorbed into the bloodstream and nourishes and helps to maintain bone tissue. Also UV light activates the pigment melanin in the skin, and thereby creates a tan. Many people feel better when they have a tan, as it gives a healthy appearance. It is also used to treat several diseases, including rickets, psoriasis, eczema and jaundice. This takes place under medical supervision and the benefits of treatment versus the risk of UV light exposure are matter of clinical judgement. Ultraviolet light can be harmful to humans. Prolonged human exposure to UV light may result in acute and chronic health effects on the skin, eye and immune system. (3) Sunburn (erythema) is the best known acute effect of excessive UV light exposure. Over the longer term, UV light induces degenerative changes in the cells of the skin, fibrous tissues and blood vessels leading to premature skin ageing, photodamage and actinic keratoses. Sun-damaged skin develops a thickened epidermis. This is caused by faster cell renewal, which is part of the immediate defence mechanism of the skin. The epidermis will return to normal provided the skin is not repeatedly over- exposed. Constant exposure to sunlight causes the melanocytes to become chronically over-active, resulting areas of excessive melanin in the skin. Eventually, areas of damaged skin made up of increased numbers of melanocytes and increased melanin synthesis develop. Up to around 85% of the overall appearance of ageing makes photoageing. It is a slow process and proceeds for several decates before it becomes obvious. The degree of photoageing is determined by the skin type and by the total lifetime sun exposure. People who spend their lives almost entirely indooors show very little skin damage. The degree of damage to tissues in different regions of the body is directly propotional to the amount of sunlight received. In chronically sun-damaged skin the epidermis as a whole becomes thicker, and loses some of its undulations. This is probably because marginally more daugter cells are produced by the basal layer, and produced more quickly. The effect is that the spiny layer and the dranular layer thicken up. The speed at which cells are replaced slows down, and some of the function of skin, including controlling water loss, may become less efficient. There is less elasticity and increased fragility. Skin becomes dry, flaky and less reflective of light. As photoageing begins, the small blood capillaries in the dermis decrease in number and the remaining blood vessels become tortous and dilated. The elastic fibres degenerate, producing a thickened mass that replaces the collagen. Seriously photoaged skin is dry, deeply wrinkled, yellow and rough. It may be marked with darkly pigmented or whitish spots, which respectively show where levels of pigment are higher or lower than normal. With increasing sun damage small blood vessels in the dermis will become more obvious and will form the red, finely branching, spider-like marks (â€Å"broken veins†). These blood vessels are easily damaged, resulting in greater fragility of the skin, with the development of spots. Loss of elastic fibres around the blood vessels of the lower lips and ears – areas especially sensitive to chronic sun damage – may result in dilated veins. On the other hand, in protected skin the vessels tend not to be so dilated or damaged. As its worst, skin that has been over-exposed to the sun for many years looks like old leather. Constant exposure to UV light over many years can result in warty spots on the skin, called actinic keratoses. The appearance of actinic keratoses means that the skin has received far too much sun and could develop a skin cancer eventually. (4) There are three main types of cancer: Basal cell carcinoma is the most common form of skin cancer. The skin is formed of three layers. The deepest, the subcutaneous layer, is composed of fat and connective tissue and connects the skin to the underlying muscle. Above that is the dermis, the layer that containssweat glands, oil glands, and other structures of the skin. The third layer, on the surface is called the epidermis; it is there that most skin cancers arise. Basal cell carcinomas arise in the lowest of the epidermis, the basal cell layer. This type of cancer can have many different appearances: a red patch or irritated area; a small, pink pearly bump, a white or yellow scar-like area; a smooth growth with a dent in the center, or an open sore that bleeds or oozes. Basal cell carcinomas rarely spread throughout the body and death from them very rare; however, because they often occur on the face, their locally destructive effects can result in serious cosmetic deformity if not diagnosed and treated early. Squamous cell carcinoma arise from the upper levels of the epidermis, usually on places that have been exposed to the sun. Squamous cell carcinomas are most commonly found on the ears, the face, and the mouth. This type of skin cancer often arises from a precancerous lesion known as an actinic keratosis, a type of lesion that appears as a rough, flat pink spot. If the lesion becomes cancerous, it's usually raised above the normal skin surface and is firmer to the touch. Squamous cell tumour tend to be more aggresive than basal cell tumours, and are slightly more likely to spread to other parts of the body. Melanoma, the most serious form of cancer, is not as common as the other two major types of skin cancer (basal cell and squamous cell cardinomas). Melanoma begins in melanocytes, the cells in the epidermal layer of the skin that produce the pigment melanin. Melanin in normal melanocytes produces â€Å"tan† skin as a response to damage from UV light. Melanoma can arise by several routes. Sometimes it arises directly from a melanocyte. Sometimes, the melanocyte first turns into a normal mole or irregular mole, and then becomes cancerous. Melanocytes can also be found in the eye and internal organs, where they also become cancerous on occasion. Melanomas are cancerous, but the large majority do not spread right away. Many begins as a â€Å"melanoma in situ†. During that stage, the growth does not venture beyond the very most superficial layer of skin, the epidermis. In a second stage, melanoma can penetrate the lower layer of the skin, the dermis. If the melanoma penetrates very deeply into the dermis, it may progress to a vertical growth phase – in which it can metastasize, or spread throughout body. Melanoma more often shows up on the trunk of the body and on the arms and legs, it can develop on any part of the body – including those never exposed to the sun. 14) A large proportion of skin cancers can be prevented and, if not prevented, they are curable if recognised and treated when at early stage of development. UV can also damage the surface of the eye, called the cornea, and cause cataracts, macular degeneration, scarring on the cornea and skin cancer of the eyelids and area around the eye. UVB can cause a sunburn on the cornea, the clear membrane that covers the front of your eyes. Corneal sunburn, called photokerastitis, can occur after long hours at the beach or on the ski slopes without sunglasses or goggles. It is not permanent, but it can be painful and cause temporary vision loss. Sun damage can also cause scars on the surface of the eye, called pinquecula, which are raised, yellowish, benings lumps that grow near the nose. These can be removed wity surgery. (8) More serious effects of UV are cataracts and macular degeneration. Cataracts – the clouding of the lens of the eye, the number one cause of reversible blindness – and macular degeneration are the leading causes of decreased vision among people older then 60. Cataracts can be treated with surgery. The UV damage to the eye is cumulative and much of it is preventable by wearing quality sunglasses or contact lenses to make sure they block UV light. They are a sunscreen for our eyes. (10) All people regardless of skin pigmentation, are susceptible to damage to their immune system as a result of UV light. The absorbtion of UV light leads to immunosuppresion. As UV light are absorbed by a human being, there is a decreased immune response. This reaction is favourable because there is no excessive swelling and damage to the skin as result of sun exposure. The drawback of decreased immune response is that when infection diseases do attack the body, a significant forceful immune reaction is needed. As a result, cancer often developes and spreads in the body because the immune systems has not the strenght to fight it due its suppresion by damage UV light. Other immune system damage is seen in the form of skin hypersensitivity and reactions to certain medications. UV light is very dangerous to the human immune system and should be avoided to prevent cancer and other infectious, life-threatening diseases. (16) Cold injuries result from overxposure to cold air or water and occur in two major forms: localised injuries (such as frostbite) and systemic injuries (such as hypothermia). (4) The risk of serious cold injuries, especially hyporthermia, is increased by youth, lack of insulating body fat, wet or inadequate clothing, old age, drug abuse, cardiac disease, smoking, fatigue, hunger and depletion of caloric reserves, and excessive alcohol intake (which draws blood into capilaries and away from body organs). (1) Frostbite is a medical condition that can happen to anyone. It is when the skin and/or tissue under the skin freezes and causes cell damage. This is caused by exposure to cold, either through the air or through a chemical exposure. When people are exposed to cold with the extremities including their feet, hands, nose, ears, and face being at the highest risk, the blood vessels constrict. This is a natural reaction to prevent body heat loss and hyporthermia. With the loss of warming blood flow the fluid within cells and tissues start to freeze forming ice crystals. These ice crystals take up more room within the cells then when in a fluid state, and cause the cells to rupture. Also, sudden warming can cause the cells rupture. Under extreme conditions frostbite can occur in seconds. Factors like wind chill, alcohol consumption, getting wet or being damp and how long you are exposed to the cold all impact how quickly and how severe frostbite can be. The elderly, young children, people with circulation disorders, and people from tropical climates have a higher risk factor of getting frostbite. People who have had previous cold injuries are also particularly at risk of getting injuries again in the same places. Frostbite comes in three levels of severity or degrees: *First degree, also called frost nip. It presents itself as numbed skin that has turned white in colour. The skin may feel stiff to the touch, but the tissue under is still warm and soft. There is very little chance of blistering, infection or permanent scarring as long as it is treated properly. *Second degree, superficial frostbite. It is a serious medical condition that needs to be treated by a trained medical professional. The skin will be white or blue and will feel hard or frozen. The tissue underneath is still undamaged. Blistering is likely which is why medical treatment should be sought out. Proper treatment is critical to prevent severe or permanent injuries. *Third degree, deep frostbite. The skin is white, blotchy and/or blue. The tissue underneath is hard and cold to the touch. This is a life threatening injury. Deep frostbite needs to be treated by a trained medical professional. The tissue underneath has been damaged, in severe cases amputation may be the final resource to prevent severe infection. Blistering will happen. Proper medical treatment in a medical facility with personnel trained to deal with severe frostbite injuries is required to aid in the prevention of severe or permanent injury. (9) Prevention of frostbite is actually very simple and for the most part is based on common sense. Hypothermia is heat loss at the body core, and it results from exposure to cold with the addition of other heat loss mechanisms. A healthy person's body temperature can fluctuate between 36. 1 degrees and 37. 8 degrees. Hypothermia is considered to begin once the body temperature reaches 35 degrees, thought even smaller drops in temperature can have an adverse effects. Hypothermia is divided into two types: primary and secondary. Primary hypothermia occurs when the body's heat-balancing mechanisms are working properly but are subjected to extreme cold, whereas secondary hypothermia affects people whose heat-balancing mechanisms are impaired in some way and cannot respond adequtely to moderate or perhaps even mild cold. Primary hypothermia typically involves exposure to cold air or immension in cold water. The cold air variety usually takes at least several hours to develop, but immersion hyporthermia will occur within about an hour of entering the water, since water draws heat away from the body much faster than air does. In secondary hyporthermia, the body's heat-balancing mechanisms can fail for any numbers of reasons, including strokes, diabetes, malnutrition, bacterial infection, thyroid disease, spinal cord injuries, and the use of medications and other substances that affect the brain or spinal cord. Alcohol is one such substance. In smaller amounts it can put people at risk by interfering with their ability to recognize and avoid cold-weather dangers. In larger amounts it shuts the body's heat-balancing mechanisms. Secondary hypothermia is often a threat to the elderly, who may be on medications or suffering from illnesses that affect their ability to conserve heat. Malnutrition and immobility can also put the elderly at risk. (12) The signs and symptomps of hypothermia follow a typical course, thought the body temperatures at which they occur vary from person to person depending on age, health, and other factors. The impact of hypothermia on the nervous system often becomes apparent quite early. Coordination may begin to suffer as soon as body temperature reaches 35 degrees. The early signs of hypothermia also include cold and pale skin and intensive shivering; the latter stops between 32. 2 and 30 degrees. As body temperature continues to fall, speech becomes slurred, the muscles go rigid, and the victim becomes disoriented and experiences eyesight problems. Other harmful consequences include dehydration as well as liver and kidney failure. Heart rate, respiratory rate, and blood pressure rise during the first stages of hypothermia, but fall once the 32. 2 degrees mark is passed. Below 30 degrees most victims are comatose, and below 27. 8 degrees the heart's rhythm becomes dangerously disordered. Yet even at very low body temperatures, people can survive for several hours and be succesfully revived, thought they may be appear to be dead. (12) People who spend time outdoors in cold weather can reduce heat loss by wearing their clothing loosely and in layers and by keepimg their hands, feet, and head well covered. Because water draws heat away from the body so easily, staying dry is important. Alcohol should be avoided because it promotes heat loss by expanding the blood vessels that carry body blood to the skin. Alcohol consumption, exposure to ultra violet light and cold injurys have harmful effects on our body and its defence mechanisms. It affects virtually all areas of a person's life; socially, psychologically, physiologically and mentally. It can be easily avoided by using just a little common sense.

Nitrate Contamination of Groundwater Poses a Serio Essays

Nitrate Contamination of Groundwater Poses a Serio Essays Nitrate Contamination of Groundwater Poses a Serious Health Threat Nitrates contamination of the world's underground water supply poses as a potentially serious health hazard to the human inhabitants on earth. High nitrate levels found in well water has been proven to be the cause for numerous health conditions across the globe. If we intend to provide for the future survival of man, and life on planet earth, we must take action now to assure the quality of one of our most precious resources, our underground water supply. Ground water can be defined as the water stored in the open spaces within underground rocks and unconsolidated material (Monroe and Wicander 420). Ground water is one of the numerous parts that make up the hydrologic cycle. The primary source of water in underground aquifers is precipitation that infiltrates the ground and moves through the soil and pore spaces of rocks (Monroe and Wicander 420). There are also other sources that add water to the underground aquifer that include: water infiltrating from lakes and streams, recharge ponds, and wastewater treatment systems. As groundwater moves through the soil, sediment, and rocks, many of its impurities are filtered out. Take note, however, that some, not all, soils and rocks are good filters. Some are better than others and in some cases, serious pollutants are not removed from the water before it reaches the underground supply. Now that we have a good working definition of what groundwater is, and where it comes from, just how important is it? Groundwater makes up about 22% of the worlds supply of fresh water. Right now, groundwater accounts for 20% of all the water used annually in the United States. On a national average, a little more than 65% of the groundwater in the United States each year goes to irrigation, with industrial use second, and third is domestic use (Monroe and Wicander 420). Some states are more dependent on groundwater for drinking than others. Nebraska and the corn belt states rely on underground water for 85% of their drinking needs, and in Florida 90% of all drinking water comes from underground aquifers (Funk and Wagnall 2). People on the average in the United States require more than 50 gallons of water each day for personal and household uses. These include drinking, washing, preparing meals and removing waste. A bath in a bathtub uses approximately 25 gallons of water and a shower uses about l5 gallons per minute of water flow while the shower runs. Just to sustain human tissue requires about 2.5 quarts of water per day. Most people drink about a quart of water per day, getting the rest of the water they need from food content. Most of the foods we eat are comprised mostly of water: for example, eggs, are about 74% water, watermelon 92%, and a piece of lean meat about 70%. Most of the beverages we drink are also mostly comprised of water, like milk, coffee, tea and soft drinks. And the single largest consumer of water in the United States, is agriculture. In dry areas, farmers must irrigate their lands to grow crops. It is estimated that in the United States, more than 100 billion gallons of fresh water are used each day for the irrigation of croplands (Funk and Wagnall 2). Since agriculture is the leading user of our groundwater, perhaps it is fitting, that it is also the biggest contributor of contaminating nitrates that work into our water supply each year. Agriculture and livestock production account for 80% of all nitrogen added to the environment ( Terry, et al. 1996). Industrial fertilizers make up 53%, animal manure 27%, atmosphere 14%, and point source 6% (Puckett, 1994). Just how do these nitrates get from the field into our water supply? There are two primary reasons that nitrate contaminates reach our underground water supply and make it unsafe. Number one reason is farmer's bad habits of consistently over- fertilizing and applying too much nitrogen to the soil. In 1995 America's agricultural producers added 36 billion pounds of nitrogen into the environment, 23 billion pounds of supplemental industrial nitrogen, and 13 billion pounds of extra nitrogen in the form of animal manure. Twenty percent of this nitrogen was not used by the crops it was intended. This accounts for about 7-8 billion pounds of excess nitrogen remaining in the environment where much of it has eventually entered the reservoirs, rivers, and groundwater that supply us with our drinking water (NAS 1995). The number two reason these contaminants reach our groundwater supply runs parallel

Late Adulthood and Death Paper Essays

Late Adulthood and Death Paper Essays Late Adulthood and Death Paper Paper Late Adulthood and Death Paper Paper Analyzing late adulthood and the death of an individual as a culmination of the life span development process one must understand late adulthood consists of. This paper will give a brief overview of ageism and stereotypes associate with late adulthood. This will explain how health and wellness techniques in the late adulthood stages can mitigate the negative effects of aging. As people age the social views and experiences changes in relationships and interactions with individuals, as he or she nears end of life. When closely approaching the end of life, a person has cultural and personal attitudes about death and dignity in late adulthood. Ageism and Stereotypes When examining ageism and stereotypes associated with late adulthood defines as ones prejudice or discrimination that occurs on the basis of age. When thinking about ageism one must look at the disengagement theory (Cumming Henry, 1961) that proposes that adults voluntarily reduce the contact with society rather than experiencing exclusion later and the disappointment not chosen. Other ageism statements say that older people forced involuntarily to give up participation with society. The disengagement theory justifies withdrawal from social institutions. Stereotyping defines as one making comments to someone saying that a certain age does a task that way. Stereotypes toward old people are cruel and unethical because one-day he or she will be in the same situation. Some stereotypes include older people show depression and loneliness, all old people look the same, old adults look sick, frail, and dependent, last older adults act cognitively and psychologically impaired. People who make stereotypical comments do this to build one’s own self confidence. If one researched all the data about the stereotypical comments one would see the comments made are not as accurate as he or she believes. Everyone deserves to be respected, especially as one ages. Health and Wellness Aging is inevitable, a fact that cannot be ignored. The aging process in late adulthood is called senescence. People cannot stop the effects of aging but there are alternatives that can help ease the process. These measures are not always followed because people make poor life choices such as smoking. Aging adults will even spend millions of dollars trying to slow the process of aging. No matter how much money they spend aging will occur. Most aging adults do not receive the necessary preventive services to help promote health and wellness during this stage of life. These preventive services include vaccinations and screenings. These important services help detect many diseases, delay their onset, or identify them early in their most treatable stages to ensure healthier, longer, and more productive lives for older adults (Prevention, 2011). Better people take care of themselves the longer they will live. People who balance: the right diet, making better choices and not acting sedentary has a better chance in living longer lives. With the advances in medical care, better health practices, improved nutrition, and other factors help people live longer. As long as older adults are following the correct measures, they can help counter the effects of aging because this stage here most people retire, they need to stay active and keep eating healthy foods. By not living actively can lead to his or her body shutting down, and may also lead to an early death. Many programs are available that older adults can join to help keep them on track. Aging adults can also receive information from their doctors and pamphlets from clinics that will give them a guideline to follow to age gracefully. Importance of Relationships and Social Interactions Humans are social animals, dependent on one another for survival and drawn to one another for joy, (University of Phoenix, 2010). Studies show that married older people are healthier, wealthier, and happier than unmarried people and their spouse’s support can help extend their lives. The importance for older adults to have a partner helps because they can depend on each other for help, and they can also help each partner in an area that they are experiencing trouble with because of age. Older adults experience capabilities of being able to have an even give and take relationship and give mutual respect in the relationship. * Older adults who have no partner should have social interactions daily as it has proven emotionally healthier than to be alone. Also older married adults must adjust to their interactions with his or her spouse because they will be together much more when they retire. This constant interaction can lead to disputes but has shown that older adults in a close marital relationship have been proven less depressed and less eager about disabilities that may present themselves because of age. * The importance of companionship in older adults, the average married woman will experience four to ten years of widowhood. The average man will experience none. The first two years can be especially difficult for the widow, but studies show that women come to enjoy the newfound independence and few seek new companionship. For widowers it is not the same, widowers have fewer friends and receive less support from the family. Those widowers try to interact to find new companionship. * Cultural and Personal Attitudes The aging process and developmental stages come to the end once a human being is deceased. A normal life cycle will have its last developmental and cognitive stage in late adulthood. This is a period is defined by the individual’s death. The cognitive learning and development in late adulthood shares some traits with the early stages of life. In this final stage the individual is seeking relationships with his close family and will create dependency on the family members. These dependencies are in all areas of human life. The cognitive and physical abilities of a person experiencing late adulthood are decreasing. Cultural factors play important roles in the lives of the elders. Different cultures will dictate the way that the older person will be taken care of financially, emotionally, social, and in all the remaining areas. Different cultures will have different approaches to this final stage; usually the children will adopt a more active role in their parent’s life. In this transition process that occurs in the late adulthood is a dynamic shift in responsibilities and roles. The elders will not be responsible for their children’s; the children will be responsible for their parents. This has a clear decrease in the analytical abilities. The cultural influence in the upbringing will determine if the alders will be on assisted living facility or will be solely responsibility of by family members. During this stage cognitive development is influenced by the mortality and their legacy. This stage the individual will realize his mortality and most cases assume a role of an amicable person than an authoritarian figure. The spouse also plays an important role on the individual quality of life. All the persons surrounding an individual in late adulthood will focus in providing a good quality of life, a safe environment, and a honest relation. Like in the early stages of life the family component is one of the driving entities in this stage. Family and close friend will have a direct impact in the quality of the individual. Once the individual’s need get more complicated the family will decide to take the person to a nursing home because the medical need cannot be meet by the family. The late adulthood is a stage very complex and full of different experiences. This transition stage allows the relinquishing of responsibilities to family members and in many instances they will seek the oldest knowledge. This stage should be used to resolve and organize the individual’s state. Ensuring that everything is taking resolved will provide a sense of accomplishment and serenity. At that time the main focus should be ensuring the quality of life remaining. Different cultures have different approaches to the wellbeing of the older adults; all have the same goal, to obtain and maintain the highest quality of life for the older. This is also complemented by the medical advantages available. Hospice care and pain management are some important tools available for the families to ensure dignity in this stage of life; that many consider a beginning, not the end. References Berger, K. S.

Cheating Your Way Through Exams Best Tricks

Cheating Your Way Through Exams Best Tricks Everyone knows that cheaters never prosper, but that doesn’t stop people from trying. In fact, some students are willing to put in more effort in finding ways to avoid learning than it would ever take them to actually study. Here are some of the more amusing ways that college students have invented to cheat their way through school. The Water Bottle Trick If your exam room has an open food and drink policy, this is one of the more creative options. Simply take the label off of a water bottle the night before your test. You can write your notes and answers on the white portion of the bottle and then stick it back on. Whenever you need an answer, all you have to do is take a drink. Of course, spending most of class gazing longingly at your water bottle may also make you look like a psycho. Beauty School Dropout For women, cheating can be as easy as writing infinitely small words on your fingernails. All you have to do is find a tiny pen or pencil, whittle it down to the size of a human hair, and then write your notes. Okay, so maybe it’s not so easy. Also, if you have the patience and determination to write the Pythagorean Theorum on your nails, maybe you should consider putting all that effort into studying. Hats Off to Cheating Another great way to cheat is to write your notes on the inside brim of a baseball cap. When your head is down looking at your desk, your teacher can’t see that your eyeballs are actually faced up towards the ceiling. But remember: if you don’t normally wear a baseball cap, it will look weird if you start on the day of your test. Also, anyone sitting next to you will be able to see your notes and nark you out. Sitting Pretty If you know where the exam will take place, go ahead of time and write the notes you need on the desk or the chair in front of you. This is a great option if your classroom is left unlocked and there is no chance for passersby to see you modifying the desk like a creeper. Also, you run the risk of the teacher seeing and erasing your hard work before the test even starts. Legstravagant Although this tactic can work for guys, it’s most effective for girls who don’t look weird lifting up their skirts in public. For this creative cheating method, you write the answers on your knees or thighs. Then, when you get stuck, you lift up your skirt to check the answer. While this can be a great method if you have a lot of information to review, this method often captures the attention of both the teachers and the distracted guys sitting next to you. Keeping It Kleenex If acting is your forte, the Kleenex notebook is the way to go. You can write your notes ahead of time on a single sheet of Kleenex and then stuff it in your bag. When you come into class, sniffle, cough, and sneeze your way to an A. Just be careful not to use your Kleenex for real – at least, not unless you want the answers all over your face. Sticky Situation Writing on your hands, legs, or ankles has the unpleasant side effect of not being easily removed when your teacher asks to see them. An alternative is to write your notes on a piece of clear tape and then attach it to your clothing. When you’re done, you can just throw away the evidence. That is, assuming you can still find it. Lasting Impressions If your teacher usually gives out a piece of scratch paper, this trick is perfect for you. The night before, write out your notes on a piece of paper with the blank piece underneath. Although your paper will look blank from far away, you’ll be able to read the impressions easily. But, test it first. Your teacher will get concerned if you’re randomly staring and mumbling at a blank piece of paper. Mirror Glasses Anyone who wears glasses knows that you can catch a reflection in the very upper corners if you try. You can make this even more pronounced by cutting up a small mirror and sticking two little pieces in the corners. But, make sure you sit next to someone who knows the answers. Otherwise you’ve ruined a perfectly good pair of glasses for a â€Å"D†. Cheating isn’t going to make you smarter or more capable in the long run. It can lead to failure and potential expulsion, not to mention the loss of respect of your peers and professors. But, if you truly have nothing left to lose, it can be fun to see what you can get away with! Have you ever cheated? Do you know some funny cheating tricks? How do you feel about cheating in general? Were looking forward to your comments! Feature Image Credit: Oxfordlearning

Majority Rule and Minority Rights in American Government Essay

Majority Rule and Minority Rights in American Government - Essay Example 3). Indeed, there are several places in the Constitution where suspicion of unchecked majority power is evident - from the Bill of Rights to the structure of the Senate to the Electoral College. To be sure, some historical events that ran relatively concurrent with the birth of the United States, primarily the French Revolution and its associated "Reign of Terror," provided ample illustration of the potential for majority rule to degenerate into mob rule. Majority rule means a system of government in which the will of the majority if given full force and effect within the laws and regulations of the country. It is, essentially, a pure democracy. Minority rights are those liberties and privileges that naturally accrue toward those who do not necessarily agree with the will of the majority. The latter rights have been associated with the concepts of natural law and human rights, whereby those in the minority deserve to be treated with a certain minimum level of dignity and respect simply because they are humans and citizens of the country that acknowledges and respects those natural rights. In his seminal work On Liberty, John Stuart Mill lays his doctrine of the right of individuals to act in any way they choose so long as it does not interfere with the freedom of others. This notion of liberty is essential to minority rights in a democracy. Democracy in the United States In many ways, the United States Constitution does not really set up a majority rule system - that is, it is not a true democracy. A close evaluation of the various branches of government reveals that the only body that is designed to be truly responsive to the will of the majority is the House of Representatives, established under Article 1 of the Constitution. The President is not even directly elected by the people under Article 2 of the Constitution; the Senate's lengthy six year terms arguably insulate its members from the whim of the majority (Article 1); and members of the Supreme Court, where the buck truly stops on how Americans are governed, are appointed for life by this President and Senate that are buffered from the will of the majority (Article 3). Moreover, the Constitution established a federal system in which the states retain substantial sovereignty in nearly all matters of government, greatly limiting the extent to which the central government of the U.S. has the power to impose the will of the national majority. The 10th Amendment states that all powers not specifically enumerated within the Constitution as belonging to the federal government are reserved to the states. Thus, it is necessary that some specific provision of the Constitution grants authority to the federal government in order for it to legally regulate any given area. In that vein, the commerce clause, granting to the federal government the power to regulate interstate commerce, has often been heavily relied upon to justify laws enacted by Congress. This has come to the great chagrin of many strict constructionists, who have protested the Supreme Court's invoking of the commerce clause to uphold the legality of many federal laws that have had a connection t o interstate commerce that is tenuous at best. The effects of these severe
