Twisted pair cable Essay Example

Twisted pair cable Paper difference methods of electronic communication and transmission used. Communication Devices Switches These are mainly used for local area networks (LAN). The reason behind this is that they can be used to bridge a lot of computers together. They do look like hubs but they can vary in speed. They are more intelligent due to the fact that they can send out packets from a set port. There is advantage of using a network switch, they can be used with an Ethernet cable or a fibre optic cable and they still will work perfectly fine. When connecting a router or a server in an LAN or WAN network it is slightly easier because you would just need one cable which would mostly need to a fibre optic cable, so you can get the maximum rate of transfer speed. Routers They are mainly used for connecting one network to another. They are meant for handling information and forwarding to another network connected to the router. You can either connect using wireless or a cable.

Hubs Also known as a concentrator or a multiport repeater. Used in a star or a hierarchical network setup to connect the station or the cable segments. There are two main types of hubs: passive active. Active takes the incoming traffic, amplifies the signal and then forwards it all the ports. In a passive hub it simply divides the incoming traffic and forwards it. A hub can be used to manage and allow individual port configuration and traffic. Hubs operate on the physical layer of the OSI model and they are protocol transparent. This means that they do have the ability to set upper layer protocols such as IP, IPX or a MAC addresses. Hubs just extend them do not control the broadcast or collision domains. Bridges Used to increase the performance of a network by dividing it into separate collision domains. Even though they are more intelligent than hubs due to the fact that they operate at the Data Link layer of the OSI model, they still are not able to control the upper layer protocols. On a separate segment they store the MAC addressing table of all nodes. Basically it takes the incoming frames and checks the destined MAC address and lookups it up against the store MAC addressing table and decides what to do. If the frame is comes from the same port as the destined port than it simply discards the frame. If the destined location is not known than it will be flooded throughout the outgoing ports and segments. Repeaters -One of the less complex hardware of the networking world, because it basically runs at the physical layer of an OSI model, so it is not aware of the frame formats and upper layer protocols. Repeater basically is used to expand a LAN network over large distance regenerating a signal. When using a repeater remember the 5-4-3 rule which means that a maximum distance between two hosts on the same network is 5. Use only maximum of 4 repeaters in a network and only 3 segments can be populated. Gateways Very intelligent devices, they work at the Transport Layer protocol. This is higher than the Upper Layer protocol. This means that can manage and control IP, IPX and MAC addressing. They allow IPX/SPX clients to IP/TCP uplink network to connect to the internet. A gateway in simple terms is like a post office. All the information is sent to it and then as a post office knows the number of houses in the area in the same way a gateway would know all the ports and direct it there. Cell Phones It is a piece of device which is used by a lot of people. It is a portable version and more advanced version of a normal home phone. It lets you voice calling, text messaging, the some other advanced phones even allow video calling and internet browsing. Cell phone is a full duplex device therefore you can connect it to your computer and use it as a modem even though it would be very slow. The newer released phones are somewhere near capable of the proper modem speeds. DCE DTE devices Data Communication Equipment (DCE) is basically equipment which allows communication with a Data Terminal Equipment (DTE). In another words DTE ends the communication line and a DCE provides the path of communication. An example of an DCE is an modem and a computer is a DTE. Fax Machine A device which allows you to send paper copies using PSTN lines to other people. It can also be used to send memos and other information as well. It uses the phone line to transmit the data that is sent. A fax machine has a sensor to read the data and the end of it. It will encode the black and white that it picks on the paper and moves it to the receiving end. It will compress the data before transmitting it. As soon as it receives the data it decodes and decompresses the data so it can arrange it in the way that it scanned it from the original document. There are a lot of things in a fax machine that allow it to do its function. It consists of a source projecting a light beam, a rotating cylinder and a photo electric cell. It also has paper feed like a printer. E-Mail Email also which is the short form for electronic mail. You can use e-mail to stay in contact with your friend/family even colleagues. It does it by finding out the person you want to email hes email address and then you will send him an email and click send and then that person will receive it. Signal Theory When talking about signal theory data is represented by digital format which is dependent on binary or base 2 principles. Analogue and digital frequencies are used for transmitting signals along a medium link. Analogue records the waveform as they are. Digital on the other hand turns the analogue signals normally to sets of number. Analogue signals can have varying amplitude and frequency. Amplitude analyzes the loudness of the signal and Frequency determines the pitch of the signal. Pitch mostly used to refer to low and high notes. If the frequency is lowered than you get a low note and if the opposite is applied than you get a high note. Bit is a binary digit which represents value of 0 which is normally off and 1 which is normally on. Bit can also be referred to as a electrical pulse which is generated by the inner clock in the control unit or data register. Bit can also be used for digital electronics which is another system that uses digital signals. Manipulation of a bit within the memory of a computer can be kept in a steady level on a storage device as a magnetic tape or disc. Byte which is made up of 8 bits is a unit measurement used for information stored on a computer. Synchronous Asynchronous Communication To sum up synchronous communication it is when interaction with data takes place it is done in real time. On the other hand asynchronous or delayed communication is when any data which is archived or stored and accessed later. It is important to choose the most effective delivery mode because it directly impacts the level of interaction that is going to take place. Synchronous It does not use start or stop bits but instead it synchronizes the transmission speed with receiving and sending end of transmission using the clock signals specifically built for each of the components. After this constant streams of data are transmitted between two sources. Because no start or stop bits are involved data transmission is faster, but more problems occur because if latency takes into effect then the synchronization clock will be out of timing therefore the receiving node will get the wrong timings that have been acknowledged in the protocol sending and receiving data. If this happens then data can be corrupted, missing or even wrong message. There are ways around this which take time. You could use check digits and re-synchronize the clocks so that you can verify that the transmission has been successful and has not been interrupted. Advantages of using synchronous transmission are that lower overhead and more data can be transmitted and data transmission rates are also faster. The drawbacks of using synchronous transmission is obviously more prone to problems, it is more expensive and more complex. Asynchronous Opposite to synchronous it uses start and stop bits to mark the start and end of a transmission, this means that 8 bit ASCII characters would be transmitted using 10 bits because the use of start and stop bits. For example (1)10111111(0) the bracketed out one and zero at the start and end mark the start and end of a transmission. This tells the receiving either the first character is transmitting or finished transmitting. This method of transmission is normally used when data is sent occasionally as opposed to in solid stream. Benefits of using asynchronous data is that it works out cheaper because timing is not that important and it is also simple because both end do not require synchronization. Drawback are that if a large amount of data is to be transmitted it would take a long time this is because a lot of bits are only for control uses they do not contain any useful information. Bandwidth is used to define how much volume a medium can transmit. Basically it is the maximum rate at which data can be transmitted across mediums. The more bandwidth a wire can handle the higher transmission rates can be achieved. It can also high transmission rates for multiple users. But there are restrictions in place such as if a user has been transmitting a lot of data between a period of time then a temporary limit will be put on. This is quite common with ISPs. To stop this happening to you best thing to do is not to download a lot at the same time and also close programs which use the bandwidth continuously. Radio Transmission Radio is a way of transmitting signals using varied tones which convey a message of electromagnetic waves with a frequency. Electromagnetic radiation travels in direction of oscillating electromagnetic fields which go through the air and vacuum of space. Changes in radiated waves such as amplitude, frequency or phase allow information to be carried systematically. If the radio waves pass through electrical conductors the oscillating fields induce an alternating current in the conductor. This could be detected and changed into sound or any other type of signal which is able to carry information. Every radio system has a inbuilt transmitter this is the source which allows electrical energy that produces a alternating current of a desired frequency of oscillation. The inbuilt transmitter also has a system which changes some properties of the energy produced to impress a signal on it. This change could be as simple as turning the signal on or off. Change could be more complex such as alternating more subtle properties such as amplitude, frequency, phase or combination of all three properties. The modulated electrical energy is sent via the transmitter to an antenna. Antenna changes the alternating current electromagnetic waves; this allows the waves to transmit in the air. There are drawbacks of using radio. First is attenuation can happen, this basically means the longer the wave has travelling to get to its destination the more weaker it gets. Most obvious example of this would be someone listening to FM radio in the midlands; the further he goes away from the midlands the more signal gets weaker. Microwave An electromagnetic based wave which has a range or wavelength of up to 30 GHz. Currently microwaves are getting more popular due to advancing technologies. Microwave offers high bandwidth at low cost. Most common problem with microwave transmission is reflection. Microwaves are common used for radar which pickup planes and helicopters flying in the air. Microwaves will hit the plane or helicopter and reflect back and gets calculated giving the position of the flying object. Waves are reflected due to a barrier which stops the wave from going further so it hits the barrier and reflects back. Reflection affects the signal if the reflection is not good then the reflection wont happen therefore a dead or a blank signal will be received. To minimize the effect try staying close the satellite. Wireless protocols such as Bluetooth use microwaves to transmit. Satellite Satellite is a orbiting piece of hardware which has been left floating in the air from big companies like Microsoft, satellite can be used for communication. There are also other types of satellites which are used for spying or used for online maps such as Google maps, Microsoft live maps or another services. Satellites provide high bandwidth solutions. Satellite is categorized as a WAN because it uses high speed long distance communication technology which allows them to connect to computers. Attenuation also affects satellite connection due to the same reason. If a satellite is not in the required position and starts transmitting signal it will not reach television so they might not work properly or correctly. Satellite dish has to be in the same direction as the satellite. Satellite signals reach television using a transmission antenna which is located at an uplink facility. The facility has an uplink satellite dish which would be around 9-12 meters in diameter. The bigger the diameter of the satellite the more accurate signals and better signal strength from the satellite is received. The satellite dish would be pointed towards the satellite and the uplinked signal is received by the transponder at a certain frequency. This frequency is normally C-band (4-8 GHz) or KU-band (12-18 GHz). The transponder then retransmits the signal back to the earth. NTSC, PAL or SECAM are three broadcast standards used through out the world. NTSC is normally used in the US, Canada, Japan, Mexico, Philippines, South Korea and other countries. PAL which stands for Phase Alternating Line is an colour encoding system which is used by over 120 countries in the world. In a few years time most of the countries will stop using PAL and either change to DVB-T SECAM It is sequential colour with memory is the analogue colour television system. SECAM was Europes first colour television standard and France currently uses it. The analogue signals for the three broadcasting types are transmitted via a satellite link scramble or unscramble. The analogue signal is a frequency modulated and transformed for a FM to something called baseband. The baseband fuses the audio and video sub carrier. The audio sub is further demodulated to provide a raw audio signal. Digital TVs that transmit via satellites are normally based on open standards such as MPEG and DVB-S. MPEG which stands for Moving Pictures Experts Group is a compressed format which code moving pictures and associated audio information. There is also MPEG 2 which is a digital television signal which is broadcasted via terrestrial cable and direct broadcast satellite TV systems. DVB-S which stands for Digital Video Broadcasting is a standard for satellite TVs which forward error coding and modulation. It is used by every single satellite that serves a continent. Standards Organizations There are difference types of standard organizations. These are the various types of standard organizations TIA/EIA, RS-232, IEEE, ISO, OSI and Manchester Encoding. ISO/OSI International Standards Organizations Open System Interconnect (ISO/OSI) is the standard model for networking protocols and distributed applications. ISO/OSI defines seven network layers. 1. Physical 2. Data Link 3. Network 4. Transport 5. Session 6. Presentation 7. Application I will be only be explaining in-depth the first network layer: Physical. This layer defines what cable or physical medium to be used. There are lots of different types of cable thinnet, thicknet, TPC, UTP. All of these mediums are functionally the same. The major difference between the various cables is the cost, convenience, installation and maintenance. Converters from one media to another operate at this level. TIA/EIA Telecommunications Industry Association Electronics Industries Alliance (TIA/EIA), state the standards which should be used laying cables in a building or a campus. TIA/EIA describes how a hierarchical topology should be laid out. A system where a main cross connect system is used and connected using a star topology using a backbone cabling through a intermediate or a horizontal cross connect. This type of cabling or similar is also used for laying out telecommunication cables. The backbone cabling method will be used to connect the entrance facilities to the main cross connect. In areas such as office a horizontal cross connect for the consolidation of the horizontal cabling, which extends into a star topology. Maximum stated horizontal cable distance should anywhere between 70M-90M. This applies to TTP (Twisted Pair Cable), but the fibre optic horizontal cabling has a set limit of 90M. IEEE Institute of Electrical and Electronics Engineers allows the development of Electro Technology which in other words applies to electricity applied to technology. Societies like the IEEE Computer Society are subsidiaries of the IEEE itself. This standards organization also publishes journals. Devices such as digital camera need set amount of bandwidth speed so it uses a IEEE plug. Any device that uses the IEEE standard uses a twisted pair cable. Signalling Standards NRZ- It stands for Non Return to Zero. It is a binary code normally used for slow speed synchronous and asynchronous transmission interfaces. Ones is represented as a small voltage and zero is negative voltages. They are transmitted by either by set or constant DC voltages. It also uses additional synchronisation so it dose not lose any bits in the process. NRZ-L Non Return to Zero Level is similar to NRZ, but it not a binary code. Same as NRZ one is represented as small voltage, but zero is also represented as a small voltage but it is not as big voltage as one, Therefore it allows more data to be send without a lot of signal change. NRZ-M Non Return to Zero Mark again similar to NRZ, but one is actually represented by a change in physical state and zero is represented as change in physical state. This basically means that there is no voltage when there is no change in physical state. RS-232 This standard applies to serial data transfer such as the 9 pin serial connecters which are commonly used on a computer motherboard. The data is sent in as time series of bits. Synchronous Asynchronous is both supported by this standard. This standard and states the number of control circuits that can be or need to be used to connect the DCE DTE terminal with one another. Data and control circuits which are signalled from a DTE connected to a DCE or vice versa will always flow and operate in one direction this is called half duplex. Only full duplex allows data to be sent and received in both directions at the same time. Manchester Encoding Data bits which are represented by transitions from a logical state another is called Manchester encoding. This is a digital type encoding. In this encoding the signal is self clocking because the length of every data bit is set by default. Depending on the transition direction the state of the bit can be analyzed.

Resume Writing Advice and Things to Avoid in Your Resume

Resume Writing Advice and Things to Avoid in Your Resume Resume Nightmares: Things to Never Put on Your Resume The comfortimg feeling of warm summer days may still be present in our lives, but, nonetheless, fall is already here. Still not convinced about that ï Å ? Have a look at the shop windows of the supermarkets nearby that have already started to sell their scary costumes and masks. With frolic witches and orcs, summers magic may quickly turn into a real nightmare. Even though nightmares make you wake up in the midst of night in cold sweat, they may also quickly become a reality. People sometimes consciously do things in their everyday life that can become real nightmares writing CVs, for example. Hardly anyone plans to devise a ghoulish resume; however, it frequently happens. Therefore, to introduce you to the festive mood of Halloween, we have created a list of common mistakes that make resumes look really disgusting. We have also prepared some resume writing tips to take into account when you wonder how to make a resume. The Slasher Instead of brandishing a shiny blade, an applicant will most probably provide a resume that was shortened beyond anything comprehensible and understandable. When looking at it from a distance, it may seem that the CV has all the signs promising it to be good (the format is OK, the fonts are legible, etc.), but when looking at it closer, there is nothing more apart from the lists, bullet points, and some wow words. Instead of providing a list of your benefits and strengths, consider connecting your experience and qualifications with the position you are applying for. The Psycho Hmm ... does the spelling seem rather off? Well, probably, it does. With the inception of numerous spellcheck programs, many pains regarding spelling were eradicated. However, spellchecks do not always guarantee you success. So, spend some 5-7 minutes and proofread the resume on your own or ask someone to throw an eye on it. The Blob This is a CV that is no longer a concise document that allows recruiters or HR managers to make out what qualifications or experiences the applicant has. To make it clearer, I mean that it would be proper to compare such resumes to small novellas. However, you must understand that adding more pages to your CV wont increase your hiring perspectives. Crying Wolf(man) Little lies may be fairly OK with you in your everyday life, for example, when you tell your Mom that the meat she baked is delicious although you have recently decided to be a vegetarian. However, when it comes to your CV, such lies are totally unacceptable. If you think that some small exaggeration wont spoil anything, youd be amazed how all these lies can turn against you in your future workplace when, for instance, you will be delegated an assignment that you havent a clue how to deal with. To sum up, take into careful consideration all of the aforementioned tips and you will be amazed how easier it will be to write your next resume.

Marketing - Essay Example These strategies include the reduction of the number of materials for packing used, the use of packages that are environmentally friendly, use of reusable containers and giving support to the services that involve the collection and recycling of packages (Murphy & Donald, pp 203 & 204). The improvement of the performance system can be affected by the reduction of packing. For instance, the carriers’ tariffs and carriers’ classifications affect the nature of packaging and the packing techniques that should be used. Moreover, the specifications of carrier for defensive packaging cut the probability of destruction to products during carriage; this decreases the loss amount and the damage allegations that do not favor the carrier (Murphy & Donald, pp 206 & 207). Among the ten principles of material handling, the most surprising ones are the ergonomic principle and the work principle. The ergonomic principle aims at adapting work to suit the workers ability. This principle is surprising because of the fact that it tries to encompass the workers mental tasks something that appears almost impossible. The other principle is surprising because the minimization of material handling work without sacrificing productivity is not an easy task and is tricky (Murphy & Donald, pp213). The fragmented logistics and unified logistic of the organizational structure are comparable because, in both, the multiple logistics activities can be put in the same department despite their differences. These two logistic structures, however, differ because, in fragmented logistics structure, the activities management is in multiple departments while in the unified logistic structure, all the activities are managed in one department. Moreover, the classification of unified logistics structure is based on the quantity and the action given to the department. The classification of fragmented logistic structure is, however, based on quantity and the activity given to

Bipolar disorder Research Paper Example | Topics and Well Written Essays - 750 words

Bipolar disorder - Research Paper Example We can therefore know of our safety from mental disorders through gaining knowledge of symptoms of the disorders and establishing their absence. This, however, can be done better through specialists’ advice (Cleveland, 2009). Personal perception and understanding of mental disorder My personal opinion on mental disorders has changed to identify positivity in challenged individuals. Previously, I held the perception that the disorders cannot be managed for the victims’ positive lives. I have however learnt that the disorders are common among people but are managed to insignificant levels that allow the individuals to lead normal lives. I also now understand that mental disorder victims require psychological care support for proper management of their conditions (Helpguide, n.d.). Understanding mental disorders Understanding mental disorders should adopt a systematic professional approach that establishes root causes of the disorders. This is because of the level of compl exity and diversity of the disorders with different causes, either psychological or biological. Such an understanding develops a basis for managing the mental disorders (Nairne, 2008). Impacts of culture on diagnosis of mental disorders Culture has direct impacts on diagnosis of mental disorders through defining abnormal behavior. ... Its susceptibility level is uniform across gender as men and women shows almost same prevalence rates. Women are however slightly more vulnerable to the disorder. Bipolar disorder majorly develops during a person’s early ages, normally teenage, and predominantly consists of â€Å"depressive and maniac episodes† that alternates or simultaneously manifest (Brown, n.d., po. 1). It is estimated to affect at least ten million individuals in America, impairing the victims’ attitudes, physical potential, and ability to work. Even though it is chronic, its symptoms are periodic and are manageable through medications (Duckworth, 2006). Diagnosis Diagnosis of bipolar disorder is efficiently done through trained healthcare personnel or a specialized expert such as psychologist. It may be achieved through â€Å"physical examination, an interview, or lab tests† (Nimh, 2012, p. 1). Physical examination for example identifies a person’s abnormal energy and physica l activity levels while interviews identifies significant changes in attitudes and behavior. Diagnosis can also be done through a psychiatric evaluation (Nimh, 2012). Treatment There is currently no identified treatment for bipolar disorder. A number of treatment for managing patients’ symptoms are however available to prevent hospitalization and advancement of the disorder to more serious stages. Application of â€Å"mood stabilizing medications,† â€Å"atypical antipsychotic medications,† and â€Å"antidepressant medications† has for example been adopted with each category consisting of a variety of drugs (Nimh, 2012, p. 1; Brown, n.d). Evidence based practice that identify treatment models also integrates with medicinal approaches to facilitate management of the disorder. The approaches’ diversity

Analysis on All the pretty Horses Essay Example for Free

Analysis on All the pretty Horses Essay The title of Cormac McCarthys novel All the Pretty Horses, reflects the significance and variance of roles that horses play in this coming-of-age story, as they relate to John Grady Cole who is the focus of the novel. The horse, which was the social foundation of Western American culture then, is described as an economical and practical asset to the boys John Grady and Lacey Rawlins. However, the author also describes horses abstract qualities using idyllic and impassioned diction, depicting them as animals of a highly advanced spiritual nature, similar to humans in some ways. John Grady has an intimate relationship with all horses and understands the world of horses extraordinarily well. On his journey from Texas to Mexico, he learns that the world of men is very different from that of horses and is forced to rethink about the relationship between humans and horses. John discovers that his preconceived notions about men and human society are false. He finds that they do not live in a romantic world, as he had believed. Therefore, the title that McCarthy has chosen is ironic and symbolizes the change that John experiences. The author uses the title to represent Johns initial perspective on the world, which turns out to be the opposite later on. Johns life, like all of Western American society during the timeframe of the story, revolved around horses. In fact, I think that he is able to understand the horses more than he does about men. The horses in the novel represent strength, untamed passion, and most importantly, freedom of spirit. The veneration that the vaqueros have for horses is apparent in the tales Luis tells the boys. the old man only said that it was pointless to speak of there being no horses in the world for God would not permit such a thing (111). I feel that this quote demonstrates to the readers very well on the strong feelings of passion of the vaqueros, cattle-ranchers, that they value horses so highly that they are able to regard themselves as nearly divine. It also reinforces Johns romantic notion that horses are highly spiritual beings. Like the vaqueros, the boys respect the horses, and these animals play large roles in their lives. The boys use horses in many ways throughout the novel, such as companions and as means of transportation or escape. John even has dreams about horses, as his thoughts were of horsesstill wild on the mesa whod never seen a man afoot and who knew nothing of him or his life yet in whose souls he would come to reside forever (118). This style of expression used in referring to horses here wild and souls is idealistic and almost poetic. Furthermore, the fact that John dreams about horses in this way and that he wants to reside forever in their souls shows that he, like the vaqueros, thinks of them very highly. Throughout the novel, the author does not fail to use romantic and emotional language to describe horses and their connections to humans. By using venerating diction in describing the horses, the author portrays these animals as noble being with wild spirits. Besides that, with vivid imagery, the author is able to paint us a poignant picture of horses. The painted ponies and the riders of that lost nation came down out of the north with their faces chalked and their long hair plaited and each armed for war which was their lifeWhen the wind was in the north you could hear them, the horses and the breath of the horses and the horses hooves that were shod in rawhide (5). This introduction of horses in the beginning of the novel demonstrates the passion and dedication that the author attributes to horses. The mood created by words such as painted ponies and the breath of the horses is passionate and emotionally charged. The author also continues to describe the raw energy and life that f lows through the horses. John Gradywas holding the horsewith the long bony head pressed against his chest and the hot sweet breath of it flooding up from the dark wells of its nostrils over his face and neck like news from another world (103). These metaphors such as the dark wells of its nostrils and news from another world create a forceful likeness of mysterious animals with a nature that is foreign to humans. The horses hot sweet breathflooding up displays the life and energy that fill the horses. This mysterious energy is also apparent later, when the author writes, He rode the last five horsesthe horses dancing, turning in the light, their red eyes flashingthey moved with an air of great elegance and seemliness (107). This imagery of red eyes flashing and horses dancing is very mysterious yet still striking. The descriptive detail is very cinematic, and any of these scenes could easily be made into a movie. These extremely in depth  descriptions are so exaggerated that they are almost unrealistic, but they are able to create the desired effect in making horses seem mystical and bizarre. These are the romantic creatures that John sees, the pretty horses that can be taken off the title. John Gradys connection with horses is as mystical as the horses themselves. He is one way or another, able to communicate with all horses on a deeper level than any other character in the story. This is evident on the Hacienda in the scene in which John and Rawlins are breaking some new horses. John cupped his hand over the horses eyes and stroked them and he did not stop talking to the horse at all, speaking in a low steady voice and telling it all that he intended to do and cupping the animals eyes and stroking the terror out (103). Johns ability to stroke the terror out of the horses is just like in a case of a parent calming a frightened child. Obviously, he must have some natural tie with these animals if he is able to do this. Indeed, the author has already unambiguously stated that such a bond does exist between John Grady and the horses earlier on when he writes, The boy who rode on slightly before him sat a horse not only as if he had been born to it which he was but as if were he begot by malice or mischance into some queer land where horses never were he would have found them anyway (23). This passage shows that Johns relationship with horses extends into the metaphysical range, a view that is reinforced throughout the novel as more is revealed about John Grady and the horses. As Luis says, the horse shares a common soulif a person understood the soul of the horse then he would understand all horses that ever were (111). It seems like as if the author is trying to tell us that John Grady has this ability to be familiar with the soul of the horse, and that is why his relationship with horses is so unique. Johns reliance on his knowledge of horses as a guide in the world of men eventually reveals to him that the two species are actually very different. When John starts out on his journey, he has very little knowledge about the inner workings of the human society, but he has superficially assumed men and horses to be similar. As the author writes in the opening of the novel, What he loved in horses he loved in men, the blood and the heat of the blood that ran them. All his reverence and all his fondness and all the leanings of his life were for the ardenthearted and they would always be so and never be otherwise (6). John knows that horses are ardenthearted and believes that men must be the same too. He thinks that his journey will be a romantic and passionate one, like the horses he loves, and will strengthen his view of the world. However, he soon learns that his assumption is not what the reality is. Before anything unfortunate happens to him, John hears from Luis that among men there was no such communion as among horses and the notion that men can be understood at all is probably an illusion (111). The first doubts then began to creep into Johns mind, and eventually, he finds out about this personally. Instead of pretty horses, Johns journey is filled with murder and stealing, prison and broken hearts. His ill-fated journey proves clearly about Luis point, and totally destroys Johns belief that the world of men is at all an understandable thing. Finally, when it is all over, he returns home disappointed, only to find that both his father and his Abuela have died. Johns fanciful concept of the world of men now has been completely replaced by a world thatseemed to care nothing for the old or the young or rich or poor or dark or pale or he or she. Nothing for their struggles, nothing for their names. Nothing for the living or the dead (301). The world of all the pretty horses is nothing to him now but a distant memory. This reveals the titles irony, a story titled All the Pretty Horses would apparently never involve the death and violence that is included in Johns travels. Indeed, John has come full circle and realized that his original assumptions about men were false. The title of McCarthys novel All the Pretty Horses is not meant to be taken literally. Before he runs away, John Grady believes in the world of all the pretty horses, because he has never known anything else. However, his time in Mexico disheartens him and forces him to believe otherwise, that the real world is not so simple, carefree, or innocent. John learns that the romanticism that he ascribes to horses cannot be applied to men. John respects horses and experiences the praise of these animals in the folklore of the day. His relationship with horses exists on many levels, by being his  transportation, his friends, and his spiritual companions. Furthermore, the author illustrates the horses with emotional diction creating almost a motif of passion whenever horses are described. Johns unusual understanding of the fervent spirit of horses leads him to believe that men are the same. However, on his bleak and disappointing journey, he learns that men do not have the same passion of s pirit as horses. Instead, they are unpredictable, violent creatures, and their world is certainly not always pretty. I think that it is utterly important for us as readers to understand what the author is trying to tell us by looking at the title and try to understand deeper with the details that the author provides us. Initially I thought that this novel is just going to give details of various horses that man uses in many different ways. However, I was completely wrong on making the judgment by its cover title. This novel teaches us about the reality in human world that no one will be able to predict what is going happen. He illustrates the morals and ethics that have survived throughout the ages, while ending up with nothing else is left, leaving only memories to be reminders of the mysterious and naturally beautiful time period. I am sure after reading this novel, one would never be able to forget the pain, suffering, romance, and above all loyalty inscribed on its pages or in the memories of those who lived through it.

Greek Life Under Attack :: essays papers

Greek Life Under Attack According to an article written by Jay Reeves, administrators at the University of Alabama are getting involved in integrating sororities and fraternities by imposing rules and punishments for those organizations that do not comply. Since the Civil Rights Movement in the 1960?s, Americans like to think that segregation does not exist in the United States. However, sororities and fraternities across the country are being viewed as segregated. Many people in society feel that it is the administrators job to enforce integration among fraternities and sororities, but others feel that it should be up to the students to integrate themselves and that the faculty should stop interfering. Many of those who feel that integration should be left untouched by the administrations of the school know that historically Greek organizations have been segregated. For almost a century the groups have remained segregated naturally, or by choice. Since this has never been an issue before administrators should not even bother to integrate sororities and fraternities. Furthermore, what happens of no members of the opposite race want to join a traditional race oriented frat or sorority? How can administrators justify punishing Greek organizations if members of the opposite race truly have no interest in joining? However, over the years this segregation has blindly detained people from limited backgrounds to be able to engage themselves with people of other backgrounds. This is the case for the family in Rodriguez?s ?Aria.? The family?s background limits them to having interactions with people of other backgrounds. Rodriguez says, ?it never occurred to my parents that they couldn?t live wherever they chose?despite their accomplishments the confidence of ?belonging? in public was withheld from them? (658). Richard cannot interact with the other children at first because his background uses a different language, which prohibits this interaction. These examples show that segregation causes barriers to be built, and once constructed are very hard to overcome if interaction takes place at a later time. Forcing integration reverses this problem by giving a chance for various backgrounds to interact with each other. This forced integration can also bring many more options to those students who are interested in joining a sorority or fraternity thus increasing the overall memberships of the Greek community.

Effective Leadership Essay

Being an effective leader means learning who you are and what you stand for, and having the courage to act on your values. Moral leadership is quite similar to the concept of servant leadership in that the emphasis and the reward are based in doing for others. A leader serves using an ethical foundation which is then adapted and acted on by followers within the organization. Moral leadership describes how leaders make decisions according to beliefs about right and wrong. A system of morals, or beliefs, is also very personal to leaders. Dr. Martin Luther King Jr., displayed courage and moral leadership; Martin Luther King Jr. was born in Atlanta, Georgia, the eldest son of Martin Luther King Sr., a Baptist minister and Alberta Williams King. King attended local segregated public school. He entered Morehouse College at the age of 15 and graduated with a bachelor’s degree in sociology in 1948. After graduating with honors from Crozer Theological Seminary in Pennsylvania in 1951, he went to Boston University where he earned a doctoral degree in systematic theology in 1955. Throughout his education, King was exposed to influences that related Christian theology to the struggles of oppressed people. Dr. Martin Luther King Jr., operated on moral leadership, distinguishing right from wrong and doing right, seeking the just, the honest, the good, and the right conduct in achieving goals and fulfilling purpose. In May of 1963, Martin Luther King Jr., and his Southern Christian Leadership Conference staff escalated anti-segregation marches in Birmingham by encouraging teenagers and school children to join. Hundreds of singing children filled the streets of downtown Birmingham, angering Sheriff Bull Connor, who sent police officers with attack dogs and firefighters with high-pressure water hoses against the marchers. Scenes of young protesters being attacked by dogs and pinned against buildings by torrents of water from fire hoses were shown in newspapers and television around the world. During the demonstration, King was arrested and sent to jail. He wrote a letter from his jail cell to local clergymen who had criticized him for creating disorder in the city. His â€Å"Letter from Birmingham City Jail† which argued that individuals had the moral right and responsibility to disobey unjust laws, was widely read at the time and added to King’s standing as a moral leader. The demonstration forced white leaders to negotiate and end some form of segregation in Birmingham. Even more important, the protest encouraged many Americans to support national legislation against segregation. Martin Luther King Jr. and other black leaders organized the 1963 March on Washington, a massive protest in Washington, D.C, for jobs and civil rights. On August 28, 1963, King delivered the keynote address to an audience of more than 200,000 civil rights supporters. His â€Å"I Have a Dream† speech expressed the hopes of the Civil Rights Movement in oratory as moving as any in American history: â€Å" I have a dream that one day this nation will rise up and live out the true meaning of its creed: â€Å" We hold these truths to be self-evident, that all men are created equal. â€Å" I have a dream that my four children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character†. The speech and the march built on the Birmingham demonstration to create the political momentum that resulted in the Civil Rights Act of 1964, which prohibited segregation in public accommodations, as well as discrimination in education and employment. As a result of King’s effectiveness as a leader of the American Civil rights Movement and his highly visible moral and courage stance he was awarded the 1964 Nobel Prize for peace.
