Midsummer Night`s Dream Essays (724 words) - Hermia, Demetrius

Midsummer Night`s Dream In Shakespeare's "A Midsummer Night's Dream" the mortal teenage characters fall in love foolishly, and the character Bottom states, "O what fools these mortals be". They are foolish because they act like children. Although Lysander, Hermia, Demetrius, and Helena appear grown-up, when they are in love they act foolishly. The four teenage lovers are fools. Demetrius is a fool because he is unaware that his love changes through out the play. At the start of the play Demetrius does not love Helena. (II ii,line 188) Demetrius says, "I love thee not, therefore pursue me not." (II ii,line 194) "Hence, get thee gone, and follow me no more." In III ii, Demetrius after being juiced begins to love Helena. (III ii,line 169-173) Demetrius says, "Lysander, keep thy Hermia; I will none. If e'er I loved her, all that love is gone. My heart to her but as guest- wise sojourned, And now to Helen is it home returned, There to remain." This proves he is a fool, because he is not aware of his changing love for Helena. Helena is a fool because Demetrius does not love her but she still persists in chasing him. Demetrius shows no love for Helena. (II i,line 227-228) Demetrius says, "I'll run from thee, and hide me in the brakes, And leave thee to the mercy of wild beasts." (II i,line 199-201) "Do I entice you? Do I speak you fair? Or rather do I not in plainest truth Tell you I do not, nor I cannot love you?" Demetrius clearly illustrates to Helena that he has no interest, but Helena persists. (II i,line 202-204) Helena says, "And even for that do I love you the more. I am your spaniel; and, Demetrius, The more you beat me, I will fawn on you." (II i,line 220-222) "Your virtue is my privilege. For that It is not night when I do see your face, Therefore I think I am not in the night;" This proves that Helena is a fool because Demetrius does not love her, but she still persists. Lysander is a fool because he persuades Hermia to avoid death and run away with him. Hermia must marry Demetrius or she will be put to death. (I i,line 83-88) Theseus says, "Take time to pause, and, by the next new moon- The sealing-day betwixt my love and me, For everlasting bond fellowship- Upon that day either prepare to die For disobedience to your father's will, Or else to wed Demetrius, as he would," Hermia does not love Demetrius. (I i,line 140) Hermia says, "O hell! To choose love by another's eyes." Hermia loves Lysander. (I i,line 150-155) "If then true lovers have been ever crossed, It stands as an edict in destiny. Then let us teach or trial patience, Because it is a customary cross, As due to love, as thoughts and dreams and sighs, Wishes and tears, poor fancy's followers." Lysander has an alternative idea. (I i,line 157-159) Lysander says, "I have a widow aunt, a dowager Of great revenue, and she hath no child; *From Athens is her house remote seven leagues." (I i,line 164- 165) "Steal forth thy father's house tomorrow night, And in the wood, a league without the town." Lysander is a fool because he convinces Hermia to risk death and run away with him. Hermia is a fool because she risks death for love. Hermia is to marry Demetrius, or be put to death. (I i,line 95-98) Egeus says, "Scornful Lysander, true, he hath my love, And what is mine my love shall render him. And she is mine, and all my right of her I do estate unto Demetrius." Lysander suggests an idea. (I i,line 157-159) Lysander says, "A good persuasion. Therefore her me, Hermia. I have a aunt, a dowager Of great revenue, and she hath no child;" Hermia agrees with the idea. (I i,line 168-169) Hermia says, "My good Lysander, I swear to thee by Cupid's strongest bow," (I i,line 178) "Tomorrow truly will I meet thee." Hermia is a fool because she is risking death for the love of Lysander. Therefore this proves, the four teenage lovers are fools. (VI i, Theseus states) "Lovers and madmen have such seething brains, Such shaping fantasies, that apprehend More than cool reason ever comprehends." William Shakespeare's A Midsummers Night's Dream shows how childishly foolish lovers can be.

Telecommunications and wireless technology Assignment

Telecommunications and wireless technology - Assignment Example The scope of technology and communication is not limited to any particular field or scope, rather it has helped making different sectors more easy to work with. Information system is an entire concept which is based on the implementation and installing of the information system in the organizations and networks for the benefit of fast working and easy execution of tasks. Literature Review: The journey of modern communication can be stretched back to the days when the communication means were slowly being transformed from wired communication to wireless ones. The wireless concept was a totally new idea which provided the people with more options in terms of the remote facility, usage of the mobile phones on the go, better services, and many more functionalities that were simply not provided by the wired telephone networks. This wireless technology came in form of 1st generation technologies formally known as the 1.G. these standards were specified by a centralized body known as the In ternational telecommunication Union (I.T.U), which looks into the matters of communication and networks and aims for further advancements and developments. I .T.U is a centralized body that looks into various aspects of the overall communication technologies promoting safer communications, specifying rules and regulations, dedicating channels and frequencies, providing platforms for further research, collaborating with other mega partners towards improvements of the communication technologies and also ensuring that the communication technologies are incorporated into other fields for the purpose of welfare of mankind and society. The first generation technology was formally known as the AMPS technology(Arokiamary 2009) which is acronym for Advanced Mobile Phone Services, these services were characteristic of being analogue in nature, facilitating limited number of customers across a dedicated channel, and with limited or no secure mechanism for protecting the privacy and data of the customers. Another characteristic of this concept was its limitation to mere voice traffic and being void of the data communications. To bring about advancements in the concept of wireless means of communication, a step forward was taken in form of migration towards second generation technologies which were formally known as the 2.G, which again was being parented by the I.T.U. The 2nd Generation technologies were meant for overcoming all the short comings that were there in the 1st generation technologies in form of the limited capacity, limited channel and customer entertaining, less secure means of operations. All this was overcome by transferring the overall concept to digital transmission and relying on the digital signal in contrast to the analogue signals which were largely in practice in the predecessor technological servicing entity. Few of the features of the second generation technologies included digital transmission, higher frequency bands, more secure algorithms adopt ion for the purpose of improved functioning and secure services, along with the using of channels and coding techniques that made the overall process of communication easy not just for the subscribers but the service providers as well. Some of the major concepts and entities of the second generation technologies include the usage of G.S.M (Global Systems for Mobile Communications), G.P.R.S (General

ENVM510_M5GradedAssign - Assignment Example In the study related in the question, potential bias could stem from the following aspects; selection of samples, estimation biases, detection biases, exclusion bias, analytical bias and reporting bias. These biases all affected the results of the research in one way or another. The selection bias relates to bias that arises from the selection of samples for the study. These lead to a control of the results and hence a sense of bias. Estimation biases guide the study in making estimates or drawing conclusions in a study. Detection bias refers to the prejudiced mind in detecting the aspect of study. The mind would have the research emphasize a specific set of people while ignoring others that could easily prove helpful to the study. Exclusion bias comes in when a study seems to exclude a given set of people from the study yet could provide reasonable samples to provide a reasonable outcome. Exclusion could prove less professional in research and this could have the right people for the study closed out hence affecting the results. Analytical bias refers to that bias that arises in a research study due to poor evaluation techniques of the results. The analytical bias results at the analytical stage with many people evaluating the results badly due to the prejudicial state of their minds on the expected results of the study. Lastly, reporting bias arises from the last stages of a research. These contribute much to the report developed after that could have value based on the nature of information provided. The bias affects the research in the sense that it provides results reported with more inclination to the mindset that the researcher held during the process. The existence of bias in most of the material used for the research makes readers or the users obligated to identify the aspects of bias and their effects to the work at hand (Gerhard, 2008). Addressing the aspects of bias that exist in a research requires a thorough consideration

Strategic Management Analysis Essay Example | Topics and Well Written Essays - 2500 words

Strategic Management Analysis - Essay Example t PESTEL analysis is generally a tool that assists the organisations to make the strategies by helping them to comprehend the external environment where they operate now or might operate in the near future. PESTEL analysis will assist Thomas Cook in understanding its environment in which it operates and will assist them to build certain strategies in order to overcome the threats that it possesses (Renewal Associates, 2003). The head of the political system of Britain is a monarch. The three arms of the state as stated in the classical political theory are the executive, the legislature and the judiciary. There are three political parties in the UK system of politics namely the Labour Party, the Conservative Party and the Liberal Democrat Party (Roger Darlington, 2010). The government of the UK doesn’t permits spending its money in countries abroad and prefers its citizens to spend their money in the UK itself and take their holidays in the UK instead of abroad in order to promote domestic tourism. This might have an adverse impact upon the Thomas Cook. The economic crisis of Greece had an adverse affect on the holiday booking in the country. In addition to this it was evident that the currency rate fluctuation also has an adverse impact upon the outbound as well as inbound tourist. The value of sterling or pound in opposition to another currency has an impact upon the cost of coming to the UK for the inbound tourists. The fluctuation of currency rates may affect the tourism in other ways as well. The tour operators may find out that the charges that have been decided with hoteliers as well as transporters in different nations might increase as well as decrease because of the ‘currency movements’. There has been a trend of accessing the internet and buying the necessary goods online in the UK. People of the UK love to listen to music and radio; and like to socialise by entertaining families and friends at home rather than going outside. They are more

The Motion Detector Sensor Engineering Essay

The Motion Detector Sensor Engineering Essay Home automation is a system that uses to help the resident to do the household activity or housework. These housework or household activity can be from pet feeding, plant watering, home entertainment system and so on. It can be operate either automatically or sometime control remotely which all depend to the home resident [2]. The entire system can be controlled by using from remove control, computer, internet until telephone. The home automation covered very wide of hoe system and it is also including home security system. The home security system basically can be separate to five categories [3], there are: Detection of intrusion Simulation of presence Detection of fire, gas and water Medical alert and precise Safe closing of blind For this project, only 2 categories have been discussed. There are detection of intrusion and detection of fire. And there are 4 types of intrusion which are [3]: i) Detection of movement ii) Magnetic contact of door or window iii) Glass breaking and pressure change iv) Pressure change 2.1 Part research and analysis 2.1.1 Motion detector sensor Only detection of movement has been discussed for this project. In here, the detection of movement means the movement that cause by human being and a motion detector sensor being use to detect the motion. A motion detector sensor can separate to active and passive and it can detect motion by using optics or acoustics. An active motion detector sensor is dispersing a constant field to detect motion. The field will remains static until something is enters it then disturbs the reflected pattern. Meanwhile, a passive motion sensor is waiting in standby mode in order to trigger a threshold setting when motion is detected. However, active and passive technique both have similar disadvantage. They only can sense very limited range that may weaken with distance. As the result, combination of both techniques has been used to gain greater effectiveness to detect the motion [4]. There are several types of motion detector sensor being use in the market [5] for example: i) Infrared motion detector sensor Infrared motion sensor is the most reliable and cheapest among the entire motion sensors available in the market. The concept of infrared motion sensor is using the infrared light spectrum to measure the heat of objects that pass in front of it. Then it will compare the heating level to heating level that cause by objects that behind it. The wavelength infrared wave is between 0.7 and 300 micrometers but shorter than the  wavelength  of  visible light  but longer than microwaves that cannot be detected by human senses but can felt as the heat. This infrared motion detector sensor can be fitted with different lenses to get greater distances. Basically the infrared motion detector sensor separate to 2 types only, there are passive and active infrared motion sensor [6]. The passive infrared sensors will detect electromagnetic radiated energy that generate by external sources like thermal energy emitted by people in the infrared range as figure. The thermal energy will reaches to the sensor that comprise more than one individual  sensor which made from pyroelectric materials. This sensor will generate an electrical voltage according it is heated or cooled [7]. Figure 1: The operation of passive motion infrared sensor [8] Meanwhile, the active infrared sensors will generate a multiple beam pattern of modulated infrared energy and react if it has change in the modulation of the frequency or an interruption in the received energy. The active infrared motion basically consist emitter and receiver pairs to generate IR detection zone. However, this emitter and receiver pairs need to adjust probably to achieve the best balancing between reflected IR energy and transmitted IR energy. This balance is called as the threshold level of reflected IR. If the reflected IR energy significantly above the threshold level, IR motion detector sensor will trigger on as figure: Figure 2: The operation of active motion infrared sensor [9] ii) Microwave motion detector sensor Figure 3: The operation of microwave motion sensor [10] The microwave motion detector sensor is type of active sensor that using radar call  Doppler radar to send out microwaves in order to detect and measure the movement of an object. Then it will receive the returning waves that cause by moving object to determine the distance, direction even the speed of the object. Basically the microwave motion detector has 2 types, they called bistatic and monostatic [11]. The bistatic type contains emitter and receiver which operate separately to configure the beam to fit particular situation. It has a larger detection range which up to 1500 linear feet but it cannot define the area of detection and easy to cause the error [12]. Meanwhile, the monostatic type can define detection area based on microwave beam that it emits. The detection range is smaller than bistatic which only 400 linear feet but it more efficient [12]. Although the microwave motion detector sensor cover a larger area than infrared sensor and more reliable over longer distances, but it is least popular because of their vulnerability to electrical interference and expensive cost [11]. iii) Ultrasonic motion detector sensor Figure 4: The operation of ultrasonic motion sensor [13] An ultrasonic  motion detector sensor will detect the movement by generating the sound wave in the ultrasonic frequency range around 30 kHz to 50 kHz within the limited area [14]. It will generate a cone-shaped sound wave and listen to the echoes. . The sound wave generally inaudible to humans and most animals but it does not pass through most objects. So, if no object is moving within the zone of detection, the pattern of sound wave in its environment and the time that reflected back will remain the same. However, if something moves, the microwave detector will detect and analysis the level or phase of returning sound waves then will trigger on the sensor [14]. Basically this ultrasonic motion detector sensor separated to 2 types, there are active and passive. [15] The active ultrasound motion detector sensors emit sound waves from quartz-crystal transducers then the sound wave will cover within the field of detection. The sound wave will not disrupt if there is no any movement detected. However, the sound wave will disrupt when movement detected and reflected back to receiver. The receiver will sent the signal to control unit and trigger on the sensor by analysis its sensitivity and calibration. Although the microwave motion detector sensor very efficiency in performance, but it is weak in very short of the field of detection that only detectable up to forty feet [15]. Meanwhile the passive motion detector sensors operate on the principle of sounds for example breaking glass to trigger on the sensor. These sounds produce sound waves that detected by the sensors which same concept like the active sensors. The signal will sent to control units to determine if the sound wave pattern falls within established normal parameters [15]. Table below is the summary of technologies to detect the motion: Technique Description Advantages Disadvantages 1) Infrared [6] Active: Generate multiple beam of modulated infrared energy and receive any interrupt or change of received energy Passive: detect electromagnetic radiated energy that generate by external sources like thermal energy i) Low cost ii) Easy to maintain i) Cover very small area 2) Microwave [12] Cover area with electronic field and receive any disturb or movement of electronic field i) Cover large area ii) Quick response i)High cost ii)Too sensitive 3) Ultrasonic [15] Generate sound wave and reflect the sound wave if any disturb or movement i) Cover large area ii) Quick response iii) Long lifetime i) Easy affect by environment vibration ii) High cost Table 1: Summary and comparison of 3 technologies to detect the motion 2.1.2 Heat detector sensor For another category which is detection of fire, there also have several techniques to detect it. These techniques are sensing in temperature, humidity and smoke [3] and sensing in temperature will be discussed in this project. There are few technologies in this market to sense the temperature [16] like table: Technologies Description Advantages Disadvantages 1)Thermocouple [17] Consist junction of 2 types of metal that joined together will produce voltage which varies with temperature change i) can used in wide temperature ii)Fast response i) Low accuracy ii) short life time 2) Resistance thermometer (RTD) [18] Electrical resistance of pure metal will increase with rise of temperature i) High accuracy ii) Good stability i)Slow response ii) High cost 3) Thermistor [19] Type of ceramic resistor that resistance will change with temperature changing i) Accuracy in small scale of temperature range ii) Good vibration i) Limit in small temperature range Table 2: Summary and comparison 3 of technologies to sense the temperature in the market 2.1.3 Wireless system application Short range radio application The table below show that the summary of some short range radio application and characteristics that use in the market. Application Frequency Characteristics Security system 300MHz -500MHz,800MHz,900MHZ Simplicity, easy installation Emergency medical alarms 300MHz-500MHz,800MHz Convenient carrying, long battery life, reliable Computer accessories UHF(Ultra High frequency) High data rates, vary short range, low cost RFID (Radio Frequency Identification) 100kHz to 2.4GHz Vary short range, active or passive transponder Wireless microphone and headphone VHF(Very High Frequency), UHF( Ultra High frequency) Analog high fidelity voice modulation, moderate price Keyless entry(gate opener) UHF(Ultra High Frequency) Miniature transmitter, special coding to prevent duplication Wireless bar code readers 900MHz, 2.4GHz Industrial use, spread spectrum Table 3: Short range radio application [20] Figure 5: Radio communication link diagram [21] Figure above is the radio communication link diagram. In transmitter, the source data will send to encoder to create a group of bits then sent the signal to receiver to make sure that no any false occurrences happen. Then the receiver will check and only accept the signals that the same address bits same with it. The signal that sent which also call message frame has 4 fields [21] like figure: Figure 6: Message frame [21] The first field is called preamble that as start bits to tell the receiver the message begins. Next field is called address, it will identify address and notifies the receiver come from which units that message is coming which sent by transmitter. Then the data field will follow on which it may indicate what type of event is being signaled in some protocols. Finally last field is parity which allows the receiver to determine whether the message was received correctly or not [21]. When several transmitters are used with the same receiver, all transmitters need to have the same identification address which set by receiver where receiver need to be set to recognize the identification address of all the transmitters that used in the system. Table below is the summary of advantage and disadvantages of two addressing system [21]: Advantages Disadvantages Unlimited number of transmitter can be used with a receiver Limited number of bits increase false number and interference from adjacent system Can be used with commercially available data encoder and decoders Device must be opened for coding during installation Transmitter and receiver can be easily replaced without recoding the opposite terminal Must be used with a dedicated microcontroller and cannot be used with standard encoders and decoders Each transmitter is individually recognized by receiver Limited number of transmitters can be used with each receiver Large number of code bits reduces possibility of false number Longer code reduces probability of detection Table 4: Advantages and disadvantages of two addressing system [21] 2.2 Review of similar product No Product Specification Cost Reference 1 Motion detector alarm set Detect motion and activates alarm -Build in high output 105dB alarm -Keypad to arm or disarm and security code -120VAC adapter operate US $24.99 [22] 2 Wireless motion system CWA2000 Transmitter can transmit signal to receiver until half mile away -Activates LED and buzzer on base station when detect motion -Expendable up to 8 motion sensor -Can adjust sensitivity of detection -Receiver required AC power and 4 AA batteries for backup mode -Sensor required 4 AA batteries US $99.00 [23] 3 Skylink SC-10 wireless Home security system -Consists 2 door or window sensors and 2 keychain transmitter -Arm or Disarm by using keychain transmitter -Build in high output 110dB siren -Expendable up to 15 sensors operate by AC power and 4 AA batteries for backup mode US $109.95 [24] 4 Powermax + wireless intruder alarm -Support real time viewing from camera -Consist 3 PIR sensor and 2 magnetic door sensor with wireless -External high output siren -Sent message to user by email, SMS or phone when any incident happened -Support latchkey to inform parent when child arrive to home -Remote home management which provide control and status update up to electrical devices -Required AC power to operate  £257.00 [25] 3.7 Hardware description 3.7.1PIC16F874A microcontroller Figure 14: Pin description of PIC16F874A microcontroller [26] The behavior of the Home Security system basically control by three PIC 16F8XX microcontrollers. The PIC16F8XX microcontroller is under Microchip PIC microcontroller device and very commonly being use because of low-cost, low-power consumption but high speed in performance and I/O flexibility if compare to other device and family. The microcontroller emphasizes almost same function as a microprocessor but PIC Microcontroller only operates at very low speed or frequency which only few MHz or even lower if compare to microprocessors that operate with high speed or frequency. Besides, PIC microcontroller consumes very small among of power consumption which only around miliwatts. So, PIC Microcontroller is more suitable for home security system compared to microprocessor in terms of size, cost, power consumption and the memory to control the input/output devices. They are three types of microcontroller also take into consideration, which are PIC 16F84A [27], PIC16F874A [26] and Atmel-AT89C2051 [28].The comparison was made before the final decision make. Below is the table of comparison between 3 microprocessors: Features Microchip (PIC16F84A) Microchip(PIC16F874A) Atmel(ATmega88V) Instruction 35 single word 35 single word 131 single word Operating speed 20MHz 20MHz 20MHz Flash Program Memory 1024 x 14 words 4k x 14 words 8k x 14words Data Memory(RAM) 68 x 8 bytes 192 x 8 bytes 1k bytes internal SRAM EEPROM 64 x 8 bytes 128 x 8 bytes 512 x 8 bytes I/O Port 13 33 23 Counter/timer 1 3 2 Counter bit 8 bits 16 bits 16 bits Series Interface (MSSP) -In-Circuit Serial Programmingâ„ ¢ (ICSPâ„ ¢) via two pins Synchronous Serial Port (SSP) with SPIâ„ ¢ (Master mode) I ²Câ„ ¢ (Master/Slave) Master/Slave SPI Serial Interface Byte-oriented 2-wire Serial Interface (Philips I ²C compatible) Operating Voltage 2.0V-5.5V 2.0V 5.5V 1.8V 5.5V Software MPLAB ® IDE MPLAB ICD2 MPLAB ® IDE MPLAB ICD2 ATAVRISP

Acid Rain The topic of this paper is acid deposition, also known as acid Rain. Acid rain is precipitation, as rain, snow or sleet containing relatively high concentration of acid forming chemicals. As the pollutants from coal, smoke, chemical manufacturing, and smelting, that have been released into the atmosphere and combine with water vapor, the harmful deposition is created (http://dictionary.reference.com/browse/acid+rain). Acid rain affects many things greatly. Acid rain affects many different things and is very harmful to the environment. One aspect of the environment that is greatly affected by acid rain is soil. Acidic rain makes its way into the soil by rain falling off the branches and leaves to the soil below. Water runs through the soil on its way to different bodies of water. A process called buffering is used to neutralize acids using the base nutrients (including calcium and magnesium) found in soil (Tyson, 1992). This process helps soil resist the effects of acid rain. Thinner soils that have fewer nutrients are more vulnerable to the effects of acid rain. Thicker soils are more affective at buffering acid rain. Over many years soils that aren’t the best at buffering out acid rain can become increasingly acidic. This leads to a decrease in the ability to support healthy plant life. Over time soils may become so acidic that aluminum dissolves and is carried by rain water into bodies of water. Aluminum that is dissolved is very toxic and harmful to all aquatic life. Areas of higher elevation, such as high mountain areas, are more sensitive to the effects of acid rain. The soils are thinner and therefore are unable to buffer acid rain as well as thicker soil at lower elevations (Tyson, 1992). At high ele... ...ns use in their homes, the fewer chemicals that power plants use the fewer that will have to be emitted in to the air. Today there are laws on how much pollution is allowed to be put out in the air these laws have made significant changes. Catalytic converters in cars help reduce emissions. There has been reduction in the amount of acid rain causing pollutant to the air by humans. Eastern Canada set a cap of 2.3 million tons of sulphur dioxide to be met by 1994 and maintained until 2000. In Canada several sulphur dioxide reduction targets for provinces to the east of Manitoba-Saskatchewan to meet this cap. Roughly halve of the sulphur dioxide emissions were intended to be cut by this reduction. Acid rain affects many things in our world greatly. Acid rain is precipitation that has been released into the atmosphere and is very harmful and can do lots of damage.

Benefits of the University Model

In Stephen Joel Tractenberg article, † Education Is Not a Luxury† (p. 211-216) states his argument that our current school calendar does a disservice to both students and teachers. Tractenberg conveys that even though this last century has seen an incredible renovation in our society, there is an agrarian calendar that dominates our education that was complimentary in times of agrarian society when school was only an option part time for most Americans. Our educating the youth is not considered a necessity and in our society today and time of luxury and we take this extra (crucial) time for granted, but we maintain a calendar that reflects up to ten thousand years ago. Tractenberg also states that we will never take school seriously if we operate an ancient agrarian calendar. I agree with the Tractenberg and his promotion of the university model calendar to replace the agrarian calendar. Replacing the agrarian calendar means a fulltime student, will take school more seriously. It will define school as a job and will prepare students for college. With the agrarian calendar removed from the system students can have more time to thoroughly learn everything that is meant to teach to the students and have more time to talk to teachers during office hours. Stephen has a friend who disagrees with sex education â€Å"One of the problems, he said, was that the schools were doing things that they should not be doing teaching sex and drugs and driver’s education, as he put it. These things, he pointed out, should be the business of Maan. 2 the family† Sexual education is very important to learn in school and prepares students for the adult world, and is something that is not taught by all families to the students. I had learned things in sex education that my conservative family had not taught me or ever will. Some schools may not have the time to teach this subject without compromising time for other subjects. He states that we should lengthen the school year to have more time subjects that are academic and afterschool help for students who need it by proposing the extension of time â€Å"I’ve been suggesting, by lengthening the school year, say, to eleven months, and the school day from 9 to 5, or a full shift, whatever the starting and quitting times may be. This, I think, would have a number of benefits. † He goes on and says that teacher are permitted more prep time and students get explore extra-curricular activities in their favor. I agree with his strategy and I believe it makes efficient use of time and students will be able learn everything thoroughly and a 9-5 schedule will make school a first priority. I believe with this new schedule students will be better prepared for college. The type of schedule he proposes gets students ready for the endeavors of college because it is in fact a university model. He goes on by saying, â€Å"What I am proposing may look very much like the university model. That’s exactly what it is. Universities, like schools, are driven by their double missions of learning and service. But universities are also driven by the compelling need to be efficient† He goes on about the cost of an idle school building and how it can be utilized after school hours and I believe it’s a convincing idea. He also supports his University model by saying. â€Å"applying the university model to schools would help to create what university administrators like me spend a lot of time and effort doing—promoting an atmosphere of learning† I agree with his conclusion and he further strengthens this by admitting that school boys and girls do not feel like school is their real occupation. This is true for many high school students, they don’t see the potential in their education and don’t realize how unprepared they are for college with a short schedule. I remember my first full load of college I almost flunked every class because I was almost spoiled with high school schedule I was still adjusted to. Introducing the university model to students not yet in university will greatly prepare them and they go into universities with confidence in their success as new student because they have become accustomed to this schedule. Tractenberg explains further reasoning as to why longer hours will be beneficial to students and teachers and goes into the expanded offerings the much needed extra time can bring. He further goes on by supporting his augment by saying, â€Å"It is dismaying to me that many students come to us without any training in foreign languages, or that only a couple of languages, typically Spanish and French, were offered to them; they were offered no classics, no Russian, no Arabic, no Asian languages. I could say the same about other subjects, including art istory, advanced math, and so on. The result, in any case, is a deficit. † This is a matter of concern and putting the extra time into expanded offerings can help learn these subject thoroughly and not just a brief overview of the subject. In order to learn these subjects thoroughly, time outside of school will be needed with our agrarian schedules. The extra time will also allow student to ask teachers for outside help and in my college classes I found emailing my teachers to be a very useful tool and it has made me a better student. He further goes on and supports the occupation of teaching and conveys to us that creating a full time schedule will create future teachers. He promotes this idea by questioning the readers by asking, â€Å"Are our teachers better at their professions because they work at other jobs during the summer—often menial jobs with trivial pay and befits? Would our youngsters be better off learning from teachers who devote their full effort to teaching rather than scrabbling for a living? † This means the teachers get the chance of full time job and the pay they deserve. I notice when I do very well in a class without much effort, it is because I have a passionate teacher who loves her/his job. Tractenberg concludes his augment by saying, â€Å"education is not a luxury for subsistence farmers but a box full of tools for a lifetime, an endless series of points of departure, and a full-time joy†. With the evolution of our society changing so should our schedules. We are no longer the agrarian society we once were and Tractenberg gives an efficient university model we can use to match the present time needs of students. School is not a luxury , it is a necessity we can afford that prepares us for the future.

Free Essays on Parents And Their Children

Parents and Their Children Robert Hayden’s â€Å"Those Winter Sundays† and Adrienne Rich’s â€Å"A Woman Mourned by Daughters† are poems that are based on only one parent. In â€Å"Those Winter Sundays† the parent is a father. In â€Å"A Woman Mourned by Daughters† the parent is a deceased mother.

Chordates - Chordata - The Animal Encyclopedia

Chordates - Chordata - The Animal Encyclopedia Chordates (Chordata) are a group of animals that includes vertebrates, tunicates, lancelets. Of these, the vertebrates- lampreys, mammals, birds, amphibians, reptiles, and fishes- are the most familiar and are the group to which humans belong. Chordates are bilaterally symmetrical, which means there is a line of symmetry that divides their body into halves that are roughly mirror images of each other. Bilateral symmetry is not unique to chordates. Other groups of animals- arthropods, segmented worms, and echinoderms- exhibit bilateral symmetry (although in the case of echinoderms, they are bilaterally symmetrical only during the larval stage of their life cycle; as adults they exhibit pentaradial symmetry). All chordates have a notochord that is present during some or all of their life cycle. A notochord is a semi-flexible rod that provides structural support and serves as an anchor for the animals large body muscles. The notochord consists of a core of semi-fluid cells enclosed in a fibrous sheath. The notochord extends the length of the animals body. In vertebrates, the notochord is only present during the embryonic stage of development, and is later replaced when vertebrae develop around the notochord to form the backbone. In tunicates, the notochord remains present throughout the animals entire life cycle. Chordates have a single, tubular nerve cord that runs along the back (dorsal) surface of the animal which, in most species, forms a brain at the front (anterior) end of the animal. They also have pharyngeal pouches that are present at some stage in their life cycle. In vertebrates, pharyngeal pouches develop into various different structures such as the middle ear cavity, the tonsils, and the parathyroid glands. In aquatic chordates, the pharyngeal pouches develop into pharyngeal slits which serve as openings between the pharyngeal cavity and the external environment. Another characteristic of chordates is a structure called the endostyle, a ciliated groove on the ventral wall of the pharynx that secretes mucus and traps small food particles that enter the pharyngeal cavity. The endostyle is present in tunicates and lancelets. In vertebrates, the endostyle is replaced by the thyroid, an endocrine gland located in the neck. Key Characteristics The key characteristics of chordates include: notochorddorsal tubular nerve cordpharyngeal pouches and slitsendostyle or thyroidpostnatal tail Species Diversity More than 75,000 species Classification Chordates are classified within the following taxonomic hierarchy: Animals Chordates Chordates are divided into the following taxonomic groups: Lancelets (Cephalochordata) - There are about 32 species of lancelets alive today. Members of this group have a notochord that persists throughout their entire life cycle. Lancelets are marine animals that have long narrow bodies. The earliest known fossil lancelet,Yunnanozoon,  lived about 530 million years ago  during the Cambrian Period. Fossil lancelets were also found in the famous fossil beds of the Burgess Shale in British Columbia.Tunicates (Urochordata) - There are about 1,600 species species of tunicates alive today. Members of this group include sea squirts, larvaceans and thaliaceans. Tunicates are marine filter-feeders, most of which live a sessile life as adults, attached to rocks or other hard surfaces on the seafloor.Vertebrates (Vertebrata) - There are about 57,000 species of vertebrates alive today. Members of this group include lampreys, mammals, birds, amphibians, reptiles and fishes. In vertebrates, the notochord is replaced during development by multiple ver tebrae that make up the backbone.

Taxation and Housing Issues Essay Example | Topics and Well Written Essays - 2000 words

Taxation and Housing Issues - Essay Example Hence, in order to understand the economic feasibility of a particular country, a close analysis of the prevailing issues on taxation and housing is necessary. This paper will critically analyze various issues pertaining to taxation and housing in the United Kingdom, United States, and United Arab Emirates. Issues relating to taxation and housing in the UK The economic spectrum of the United Kingdom indicates that taxation issues have impeded the faster growth of the country. UK holding companies have been heavily suffering from tax issues in the recent years. Corporation tax deductions are available to a UK holding company on the interest payment to investors subject to anti-avoidance policies. More details on these features can be found at . The anti-avoidance provisions including transfer pricing are increasingly complex in nature and therefore the country’s holding companies are not benefited from tax reductions. In addition, a UK holding company does not get any tax deduc tion benefit while paying dividends to investors. Similarly, the tax deductions allowed to the UK’s small scale enterprises for boosting entrepreneurship actually result in a deadweight cost. This situation adversely affects the overall growth of the economy. Over the past few years, the UK government has faced a series of issues associated with the country’s corporate tax structure. In order to resolve the limitations of its corporate tax structure, the country is changing its policy from taxing worldwide profits to a more territorial taxation approach. Irish tax issues on UK transactions remain to be a major growth impediment to the UK’s business sector. Tax evasion has been a potential issue in the UK over the last few decades, and recently the country adopted tax fraud prevention measures. When an outsider deals with purchase of real property in the UK, he has to consider a number of factors including capital gains tax, stamp duty, inheritance tax, and incom e tax. The UK housing market has been struggling with numerous issues especially since the global financial crisis 2008. As a result, even small flats are becoming unaffordable to lower class of the society. Housing sector data show that affordability of housing in the UK has been getting worse since late 1990s as house prices grew faster than earnings rate. Although most of the developed countries including the United States experienced housing price increases in the beginning of the 21st century, this issue was different in the United Kingdom in two aspects. Firstly, the country’s house prices boom began earlier as compared to other developed economies, and indicated relatively sustained increases. Secondly, the regional pattern of the country was almost uniform. As per statistical data, house prices in the United Kingdom increased by 90% between 2002 and 2007. The average age of first time home buyers is also increasing in the country. Although mortgages were increasingly available to people, mounting housing prices remains to be an issue in the country. As reported by Department for Environment Food and Rural Affairs (2004), an additional 39,000 houses per annum were essential to meet housing requirements of the country effectively. The primary issue behind the housing market struggle in the UK is that the country does not have enough space to build new houses. In contrast, many people possess more
