American Dreams essays

American Dreams essays Million of Immigrants settled in United States, its diversity of different culture during 1900 1930. California is one of the highest Mexican Immigrants settled in this state. Almost all worked as agricultural wage laborers. Mexican Americans ancestry became object of one of the largest removal operations ever authorized by the United States government. Immigration and repatriation were interrupting the lives of the Mexicans and American Mexicans, as well as the other ethnic culture in the United States. Mexicans immigrants believed with the ideas that living in United States will bring the social and economic prosperity that they never had. Mexicans brought their ideas, cultural practices, and experiences to established the image of America Dream. Mexicans believed that by working hard as a farmer it would bring prosperity in their social and economic way of life. United States as the land of opportunity and security gave immigrants the ideas of American Dream, freedom, and uniqueness. With these beliefs, Mexicans did not realize that there was a hidden division along class, gender, ethnic, and racial lines over who had access to economic security and freedom. Mexicans realized that there was differences between the expectation of the of a brown Mexican field worker to the white American farm owner. Freedom to Mexican farm workers, destined to reach their goals in economic and prosperity by working for wages, putting aside savings to sent back to their family in Mexico, opened a small business or going to school. These ideas of freedom was different from white farm owners, who alleged that they should allow to hire workers for a cheap labor wages that would allow them to a big profit, which they believed that their rights to be as Americans. During the twentieth century, there were two descriptions of who was allowed to the American Dream prevailed. The first description that could have an access, unre...

Mary Rowlandson, essays

Mary Rowlandson, essays In the story by Mary Rowlandson about her captivity displays many things about experience. She viewed the experience as if she had went to hell and the Indians that held her captive were demons; Oh, the roaring and singing and dancing and yelling of those black creatures in the night, which made the place a lively resemblance of hell. Her views on the Indians were in reflection of the views of those from Europe and from her colony. They all believed that the Indians were savages that had no purpose in life and being with them made you less god-like. Mary refers to the Indians as ravenous beasts, and barbarous creatures, showing her thoughts of them. Throughout the whole situation Mary believes that God is punishing her, and views the ordeal as a lesson to be learned. She is constantly referring passages from the bible in relation to the captivity. She also views herself as a more God-like figure than the Indians. Mary is very prejudice towards the whole situation, even when the Indi ans start to treat her with kindness. A person in 2002 would have handled the whole ordeal differently because even though prejudice still does exist in society, it is not as distinctive as is was then. The majority of Americans views every color of skin as an equal or close to it, and would have viewed the Indians, not as beasts, but just as criminals for kidnapping them. I do not think that anyone would enjoy being held captive, but the views are very different since the time of Mary Rowlandson. ...

Abortion - Essay Example n argue that abortion is performed (especially in pregnancy’s first trimester) when the fetus is incapable of independent existence and so cannot be regarded as a separate entity (thereby giving the mother the right to choose to terminate the pregnancy or carry it to term) (Currie, 98). This group also asserts that teenagers who become mothers (parents) have very grim prospects for the future and that abortion also importantly serves to reduce the crimes that stem from the need to provide for the child (and its mother) (Paley, 221). Moreover, proponents of abortion observe that is medical technology reveals before birth that the child will be deformed or grow up to be sickly, abortion becomes handy in helping alleviate the pain of watching the child labor through a miserable life. However, abortion cannot be validated by such feeble arguments. Life begins at conception, and so abortion is akin to murder, which is punishable by law (Williams, 65). It is also unfair to kill an unborn child simply because life’s odds do not favor the parent(s). If all expectant parents reasoned like this, most of us would not be alive today. Even so, adoption still remains a fair option that gives both the parents and the child a chance at life. It is equally essential to note that rape and poverty are not valid reasons to terminate a pregnancy because abortion only punishes the child who has done absolutely nothing wrong and deserves a chance at life like the rest of us (Tushnet, 124). The problem is not the child (pregnancy) but rape, crime, unemployment, poor economies, and so on. Furthermore, apart from the ageless mental scars obtained from abortion, such procedures can also render one infertile or cause cancers. This is not to mention the billions of women who have died after an abortion gone wrong since time immemorial (Berlatsky, 78). Innately, all persons are capable of realizing the ills of abortion and to rightly reckon that no amount of academic arguments can make it

Other - Essay Example However, Tough’s portrayal of Geoffrey Canada’s passion to change the prevailing perspective that I share with millions of other people in America made me sit up in awe, curious to find out if his grand plans for Harlem’s children will work. His promising idea begins with very early interventions, even as early as from the womb, and to empower parents with the right skills to raise their children well. Canada is interested in combining educational, social, and medical services to help all children to grow up with the right foundations regardless of their family’s socio-economic status (4). He envisions that the only way to solve the problem of poverty in America is to â€Å"transform every aspect of the environment that poor children were growing up in; to change the way their families raised them and the way their schools taught them as well as the character of the neighborhood that surrounded them† (19-20). It would seem like a tall order, but com e to think of it, it does make sense to start a-fresh with people who are appropriately trained to combat poverty as they grow up to be intelligent, compassionate and productive citizens. My mindset before reading this book was that it is society’s fault that poverty is so widespread. The cause of the deterioration of morals is mainly due to people’s need to acquire their basic needs from a society that does not give them enough opportunities to live a high quality of life just because they are poor and uneducated. This book has caused in me a paradigm shift that problems should be addressed from the grassroots level, in this case, from childhood or earlier on. To be dependent on society or government would only be setting oneself for failure if one does not do anything out of his own initiative. Children should develop their skills early on so they can be self-reliant. Tough echoes this: â€Å"Skill begets skill; learning begets learning. Early disadvantage, if left

Automatic Fire Alarm System (A-FAS) Design

Automatic Fire Alarm System (A-FAS) Design ABSTRACT The safety of the environment and individuals is monitored and maintained by the important role fire alarm systems play. Although, the usability of many of the existing fire alarm systems is known by the users, however, they are produced with high cost thus not reasonable for the low-income users. The main objective of this project is to design a prototype of an automatic fire alarm system (A-FAS) with low cost. The A-FAS designed in this project contains two systems, the detection system and the alarm system. The detection system operates as the fire detector and consists of a smoke detector, heat detector and an emergency switch as a manual call point. This paper discusses the design and implementation of a microcontroller based fire alarm system. The detectors are placed in different zones and any signal from any detector at any zone will activate the alarm system. The alarm system consists of LEDs, LCD notification, buzzer and text message notifications. Furthermore, the system i s fitted with sensors at different zones to identify the presence of individuals, this feature aids the monitoring process of the system. The entire system is controlled by a microcontroller which is programmed using Arduino compiler. Upon completion of the prototype, the A-FAS detects smoke or any rise in temperature sensed by the detectors. Finally, when any of the sensors are triggered, the buzzer operates and the system sends a text message to the saved number. With the development of A-FAS, the safety of individuals and surroundings will be increased as the low cost of the system will promote users of all income levels to have one at their place or home. INTRODUCTION An overheated electrical appliance, a burning splinter or a burning cigarette or just about any of these can trigger a fire. Moreover, the presence of nylon settings and a sofa set which emanate poisonous gases if on fire, will render people helpless in a couple of minutes, before even realizing what is happening. ADT Security Service and the Chubb Alarm are the well-recognized companies that deal with security systems and have been the innovative leaders in security systems. The products offered by these companies vary from intruder alarms to highly sophisticated fire alarm systems. Furthermore, the systems built by these companies are high in cost and require a scheduled maintenance to be carried out by the companys specified authorities. Based upon the current existing high cost fire alarm systems that are available in the market, an automatic fire alarm system with low cost has been developed. The A-FAS consists of two subsystems; detection system and alarm system. The A-FAS detection system has smoke detecting capabilities as it incorporates an optical smoke detector. Moreover, it is interfaced with heat detector and an emergency switch. The system features counting capabilities based on infrared sensors to ease the determination of individuals in case of emergency. The A-FAS alarm system is associated with the detection system to ease the process of alarming individuals in the event of fire. The alarm system consists of LED and LCD notifications displaying the location of the fire. A buzzer is also incorporated in the system. The system sends text message alerts as it incorporates a GSM module. Finally, the main part of the A-FAS that controls the entire operation is the microcontroller. This thesis describes the design and operation of a microcontroller based fire alarm system that could contribute to saving lives and reduce property losses with low cost. Aim The main purpose of this project is to design and prototype an automatic fire alarm system (A-FAS) with effective and competitive usage and can be produced at a low cost. This system is designed to be easy to operate by any user and is user friendly. The A-FAS is also been designed using minimum hardware at the lower level of processing. The system is not restricted to the mentioned inputs and outputs, however, can be altered per customer needs without having to design a new system. Problem Identification The complexity of the existing fire alarm system in the market nowadays is too high in terms of design and structure. Due to the complexity of the system, regular preventive maintenance is required to be carried out to make sure that the system is operating well. Moreover, the scheduled maintenance adds to the cost of the using the system. Therefore, the proposed fire alarm system is designed with a low cost and can be used by any user for safety purposes. Project Objectives There are several objectives that are required to be accomplished in developing the A-FAS to determine the purpose and the direction of this project. This project aims to achieve the following objectives: To design a low-cost microcontroller based fire alarm system. To develop a prototype of the fire alarm system using smoke detector, heat detector, emergency switch and infrared sensors as inputs to the system. Moreover, using LEDs, LCD display, buzzer and text messages as outputs to the system. To develop a prototype with the capability of customizing the system to meet with the customer requirements with regards to the inputs and outputs, without having to redesign a new system. To develop an automatic fire alarm system to safeguard the user and their surroundings, while being user friendly to accommodate the need of the masses. Project Scope To achieve the above objectives, the project needs to be implemented as below: The heart of the fire alarm system is to be a microcontroller to control the entire operations involved. The fire alarm system is to count the number of individuals present in the locations where the infrared modules are installed. Capable of displaying the source of the alarm on the LCD display. Capable of sending SMS notifications via GSM module interfaced in the system. Project limitation Since the project is interfaced with a GSM module that needs a SIM card to send SMS notifications and thus the system is limited to the amount of credit available on the SIM. Moreover, the system includes infrared sensors that are used to count the number of people entering and exiting the zone and thus to make the system more sensitive and receive only the infrared radiation from the correct source, the infrared modules need to be placed with a minimum distance of 2 meters. Furthermore, to receive live data from the sensors to produce visual output to the user in terms of if any sensor is disconnected from the system, the system is required to have personalized sensors. System Overview Figure 1.1 defines the inputs and outputs interfaced to the microcontroller device. The A-FAS has the features of interfacing additional inputs and outputs based on customer needs. Color Type of sensor Infrared sensors Smoke detector Hear detector Emergency switch The A-FAS works in a loop checking all the input sources and acting accordingly. The smoke detector, hear detector and the emergency switch transmit a signal to the microcontroller once triggered, this notifies the microcontroller to hazard the surroundings via the output devices. A keypad is added in the system to allow the user to interface and monitor the system. The Atmega2560 microcontroller acts as the heart of the Fire Alarm System which controls the entire system. The signals being received from the sensors are being compared by the Atmega2560 to either hazard the surroundings for the existence of fire or to hazard the surroundings for the presence of a fault in the system. Moreover, the system can alert the surroundings via a buzzer and LED notifications as well as SMS notifications once the Atmega2560 microcontroller receives signals that there is fire present in one of the zones. Thesis structure This thesis is divided into six chapters. The first chapter explains the problem statement, objectives, scopes and limitations of the project. The second chapter in this thesis is the projects literature review, which is based on the detection components of the A-FAS, the ATmega2560 and a comparison between microcontrollers and microprocessors. Moreover, this chapter contains summary of several available inventories software available in todays market and previous projects developed by engineers. Furthermore, chapter three describes the phases involved in the development of the A-FAS. There are four phases involved in the production of the fire alarm system which include the research phase, the designing phase, development phase and the analysis phase. Chapter four of this thesis discusses the system design process involved and the hardware and software development. Moreover, chapter five explains the results of the system development of the A-FAS and its analysis based on the system operation and functions. Finally, chapter six concludes the project and the recommendation suggestions for the continuity of the project and future work. The sixth chapter aids to the continuity of the project by other individuals interested as they can refer to it to develop the system. CHAPTER II LITERATURE REVIEW As mentioned earlier in the previous chapter, cost factor plays a very important role in this project. Subsequently, to design a system with the objectives mentioned above requires research and studies that are described in this chapter. This chapter will include three subtopics, previous case study on fire alarm systems, hardware and software studies. Fire Alarm System: Related Work According to Bao Minzhong, Jianmei, Niihau Xiao and Wang [1], the function of the fire alarm system is to detect fire at an early stage providing sufficient time to produce high reliable judgment results. If the fire alarm system nosedives to notify the user in the presence of fire for the user to take appropriate measures, the system fails as alarm systems should cause the operator to respond. Moreover, Brown Campbell [2] suggested that for a system not to fail, it must require positive feedback from the operator. Nur Abd Aziz [3] proposed a fire alarm system consisting of three sensors, thermistor hear sensor, infrared sensors and infrared smoke sensors. The thermistor heat sensor was used to detect the rate at which temperature rises and high temperatures. The infrared sensors were used for intruder alarms to detect the presence or any motion, acting as a burglar alarm system. The infrared smoke sensors were used to identify fire in its early stages or smoldering. In the presence of fire, the water sprinklers are automatically switched on and the burglary alarm is activated. The known catalysts for fire is smoke, flame and heat but only smoke and smoke sensors have been applied and emphasized. Furthermore, when a fire occurs, the highly sensitive motion sensors will respond to normal environmental vibration which could be caused by moving cars or planes overhead. Furthermore, Chew and Ing Ming [4] proposed a similar system consisting of smoke detector, heat detector and a burglar alarm. In the event of smoke or a rise in the temperature, the system sends a signal to the microcontroller which in return operates a buzzer. Moreover, the microcontroller operates an auto redialing telephone programmed with specific number. This system. Moreover, the system is implemented with photo-electric sensor and inductive proximity switches. The photo-electric sensor is activated when transmitter cannot send light to the receiver. The inductive proximity switch is normally used for metal detection and activates when a metal is detected in the system. Once any of the sensors is activated, the microcontroller will sound the buzzer and flash LEDs. Chew and Ing Ming categorized the system proposed for industrial purposed. The complexity of this system contributes to the inability of installing such system at homes or offices. Detection components of the Fire alarm system Sensors are types of transducers that responds to a type of energy by producing another type of energy signal, usually electric [5]. Some of the sensors available include acoustic, biological, chemical and electromagnetic. These are used in many applications and are heavily used in the medicine industry and robotics as a source of detection components. The detection components of the A-FAS consist of smoke sensors, heat sensors and infrared sensors. Smoke Sensors Smoke detectors are devices designed to detect a fire while it is in its early stages or smoldering, duplicating the sense of smell. These devices have gained a wide usage in the residential and life safety applications. There is no debate that smoke detectors is the single most effective method of reducing fire damages and death. 90% to 95% of fire deaths occur in residential buildings (NZFS, 1993), targeting this will help accomplish the most cost-effective results. Studies of various types of smoke detectors, in particular photoelectric and ionization smoke detectors, illustrates that, one type of detector will be expected to perform better than the other, depending on the source of the smoke. Natarianni (1993) concludes that in flaming wood crib fires, the ionization smoke detectors activate before the photoelectric detectors. This conclusion is from simulated fires in hospital patient rooms. However, most importantly, both detectors activated before threatening the patients life. Moreover, a series of full-scale tests of smoke detectors installed in corridors and bedrooms of residential areas was conducted by Kennedy et al (1978). They concluded that inadequate warning in smoldering fires were often produced by ionization detectors. Subsequently, reducing the time available for escape once activated and the escape routes may be smoked-logged. Photoelectric smoke detectors contain a light emitting device, most commonly a light-emitting diode(LED), a smoke chamber and a photosensitive device that produced a monitored current from receiving light directly from the light source. The intensity of tech light reaching the photosensitive device is reduced by the smoke that enters the chamber. A drop in the intensity below a certain level causes a drop in the current produced by the photosensitive device, which is detected by the sensor control circuitry. Dropping the current below a preset threshold results in triggering the smoke alarm. Table 2.1 summarizes the advantages and disadvantages of photoelectric smoke detectors. The complete specification of the smoke detector used in the A-FAS can be obtained in Appendix A. Table 2.1: Advantages disadvantages of photoelectric smoke detector [6]. Advantages Disadvantages Sensitive to visual particles of smoke. Provide early warning. Detects smoldering low heat fires. Detects presence of smoke, not toxicity. Can be installed in any of the following typical locations: Office areas Clean rooms Atriums and corridors Sleeping rooms Storage closets Early contamination by dust causing reduced sensitivity. Must be cleaned on a regular basis. Has a potential for high false alarm rate, however, lower than the ionization smoke detectors. Heat Sensors A heat sensor detects abnormal rate of temperature rise or high temperatures. There are numbers of various heat detectors available in the market, which include: Thermistor. Thermocouple. Resistance temperature device. Diode based temperature sensor. There are certain features to consider while choosing the best heat sensor for any use. These features are summarized in table 2.2. Table 2.2 Features of various heat sensors [7]. Thermocouple RTD THERMISTOR SEMICONDUCTOR High accuracy and repeatability. Fair linearity Poor linearity Linearity: 1oC Accuracy: 1oC Needs cold junction compensation Requires excitation Requires excitation Requires excitation Widest Range: -148oC to +2300 oC Widest Range: -200oC to +850 oC Widest Range: 0 oC to +100 oC Widest Range: -55oC to +150 oC Low voltage output Low cost High sensitivity 10mV/K,20mV/K Typical output The LM35 temperature sensor are precision integrated circuit temperature sensors, which will be used to develop the A-FAS. This sensor is fully rated from -55 Â °C to +150 Â °C and with the linear scale factor of 10mV/Â °C. It operates from 4 to 30 V, has less than 60 ÂÂ µA drain current and has low self-heating (0.08 Â °C in still air). The control circuitry or the interfacing of LM35 is easy due to the low output impedance, linear output and precise inherent calibration. The LM35 series is available in hermetic TO transistor packages, while the LM35C, LM35CA and LM35D are available in TO-92 transistor package. The LM35D is also available in an 8-lead surface-mount small outline package and a plastic TO-220 package. [8] (Reprinted from datasheet of LM35 [8].) The LM35 can function as a basic centigrade temperature sensor sense temperature between +2 oC and +150 oC and can function as a full -range centigrade temperature sensor sensing temperature between -55 oC to +150 oC. Figure 2.1 illustrates the circuitry for using the sensor for both functions, where +Vs is the voltage supplied to the sensor. Adjusting the output voltage of the sensor enables the temperature to be obtained in degree centigrade. Infrared Sensors: There are many sensors available for obstacle detection such as infrared sensors, ultrasonic sensors, camera and laser based sensor system (LIDAR). In this thesis, infrared sensors are used to accomplish the task of counting the numbers of individuals in the placed installed. Low cost with accuracy is one of the main objectives of this project, hence infrared sensors were selected for the design. These sensors are widely used for measuring distances and obstacle detection and have faster response time than ultrasonic sensors [10]. Moreover, power consumption of the infrared sensors is lower than that of ultrasonic sensors [11]. Infrared sensors are categorized as diffuse reflection sensors and retro-reflective sensors. The latter is mainly used in harsh environment conditions and has a larger detection range than the diffuse reflective sensors [12]. Infrared sensors utilize a light sensor to detect a selective light wavelength in the spectrum. When an object obstructs the sensor, the light from the LED is broken by the object and the signal is not received by the receiver. ATmega2560 Microcontroller As defined by James L. Atonakos [13], microcontrollers are souped-up microprocessors with built-in features such as RAM, ROM, A/D, Interval timers and parallel input and output ports. Atmega2560 (figure 2.2), is a powerful flash microcontroller that contains many features in a 100-pin package. The datasheet of the ATmega2560 is attached in Appendix B. The definition of a flash microcontroller is that it can be programmed and erased instantly without the usage of ultra-violet light. The Atmega2560 is an 8-bit microcontroller with a powerful execution of instructions in a single clock cycle leading to the achievement of 1 MIPS per MHz, allowing the designer to optimize power consumption vs processing speed [14]. The internal architecture of the microcontroller is shown in figure 2.3. The central processing unit (CPU) is the brain of the microcontroller that controls the execution of the program, therefore able to access memories, handle interrupts and perform calculations. The microcontroller unit (MCU) consists of 256K bytes of in-system flash, 4K bytes EEPROM and 8K bytes of SRAM, which are used for memory. Other features include [14]: 86 programmable input and output ports. Ultra-low power consumption in active and power down mode. flexible timer/counters with compare modes and internal and external interrupts. Code protection facility, which is one of the best in the industry. Comparison between microcontroller and microprocessor The fact that microcontrollers may have one or two operational codes for moving data from external memory to the CPU, whereas, microprocessors have many operational codes, is the best way to exemplify the contrast between microcontrollers and microprocessors. Microcontrollers have many types of bit handling instructions, however, microprocessors have one or two. In conclusion, the microcontroller is concerned with rapid movement of bits within the chip, whereas, microprocessors are concerned with rapid movement of codes and data from external addresses to the chip. Microcontrollers can function as a computer with the addition of no external digital parts, however, microprocessors must have many digital parts to be operational [15]. OrCAD Figure 2.4 shows the OrCAD software used for circuit designing, testing and circuit analyzing. Generally, OrCAD is a software used to produce printed circuit board (PCB) layouts. The circuit was drawn onto the PCB board using OrCAD Capture, where footprints for each component was researched. The design rule check ensures that there are no errors present in the circuit. Arduino IDE The Arduino IDE (Integrated development environment) is a platform application from ATmega microcontrollers. Figure 2.5 shows the Arduino version used to compiling the program. Arduino IDE is used for writing, debugging, and optimizing ATmega microcontroller applications for firmware product design. Arduino programs are written in C or C++ and the software comes with a library called wiring which makes may common outputs and inputs operations much easier. Fire alarm systems available in the market There are several types of fire alarm system available in the market today. The various fire alarm systems from different developers vary in terms of implementation and functionality. Research has been carried out to investigate the technology and features used to develop each of the systems and compared them with the proposed A-FAS system. Table 2.3 concludes the results on the research, [16] [17].

Cost $2,055 $1,800 CHAPTER III Methodology This methodology chapter describes the planning and research involved in the development of the entire A-FAS system. The progress of this project was due to the division of the work in four phases; research phase, designing phase, development phase and the analysis phase. Introduction The fire alarm system described in this thesis is divided in to two sections, which are the hardware and the software sections. These sections play a vital role in the effectivity and the functionalities of the system. In order to start developing the project, there are few procedures that must be considered. Thus, earlier planning is important in designing and developing the A-FAS. The related phases have been illustrated in figure 3.1. Research phase The first phase of this methodology deals with the systems literature studies, research and analysis. Problem identification is included in the research phase. Moreover, the system objectives are determined by observations and theoretical information obtained from internet sources, journals, books and magazines. During this phase, the system requirements are determined, which include the hardware and software interfacing. Furthermore, the research and analysis conducted on the existing systems available in todays market is included in the research phase, as well as reviews on previous projects developed by organizations or individuals. A few problems have been identified based on the current research that has been done, which include: Burglar alarms are combined with the fire alarms in the same system, leading to confusion and inability to identify the source of the alarm by the user. The systems available are designed for specific purposes, providing the user with no options of customization of the fire alarm inputs and outputs. The cost of the systems is too high for low income individuals to secure their lives and properties by purchasing one. Websites and documentations were the source of reviews on analysis activities conducted in this phase. The system planning and development scheduling were then determined in this phase which suited the chosen development methodology. Upon completion of this phase, the system scopes, specifications and Gantt chart were produced. Designing Phase The second phase of the system development is the designing phase. The main objective of this phase is to translate or transform the requirements and analysis obtained from the research phase into design specifications for system implementation and construction. This phase involves a vital task for the success of the automatic fire alarm system, which is the hardware design of the system. Designing of the A-FAS hardware system The A-FAS hardware design involves detection components and the microcontroller. The detections components which are the smoke detector, heat detector, infrared sensors and an emergency switch are connected to the microcontroller. The latter is the control unit identifying the source and location of the fire if any of the input detection devices is triggered. A text message will be sent and a buzzer will be activated for individuals to evacuate the premises. Smoke sensors The system has been implanted using a Mercure photoelectric smoke detector. The system has the capability of being interfaced with most of the market available smoke detectors. However, to interface the smoke detector to the microcontroller, the smoke detector circuit is required to be altered. The smoke detector then sends a signal to the microcontroller in the event of emergency. The photoelectric smoke detector used in this project is very effective and highly recommended by users, with a low cost. These devices offer high power dissipation capability and are ideally suited for hostile environments. Heat sensors The LM35 temperature sensor has an output voltage which is linearly proportional to temperature in centigrade, thus the sensor is suitable for the project. The sensor draws very small amount of current which makes it very low self-heating. Figure 3.2 describes th

Essay --

Pets are important members of the family. In more than 60% of households in the United States today according to Jill Weisenberger Rachel Bajema owns a pet. A veterinarian is a person qualified to treat diseased or injured animals. Pets of home owners are not their only patients. Vets can also look after zoo animals, livestock, and animals in sport. Vets can also help with animals’ diseases that can infect humans. A veterinarian job is very important. Animals are important to human life, both to share affection, and financial purposes, and a vets job is to make sure they are healthy and stay that way. What we call "veterinary medicine† has been around as long as people and animals have worked and lived together, according to â€Å"Care of pets, and a history of Veterinary medicine.† The veterinarian dates back from 4,000B.C up to 2,500. The earliest veterinarian work was found in China, Rome, Egypt, and Europe. People that study history have found Chinese writings about the diseases of horses, oxen, and buffalos that dates all the way back to about 2,500 B.C. In about A.D. 500 a Roman wrote a book on what veterinarians do to help animals. Nothing else was written after that until a thousand years later when another book was written. Yet, there were those like Romans that had to learn their skills by working directly with the animals. The first school that taught people about scientific veterinary medicine was in Europe in the mid-eighteenth century-less than three hundred years ago. It has become more famous as time went by. In the end of the nineteenth century, veterinary schools had been established in the United States and also in many other countries. In veterinarian medicine, there are two positions. One of the positions is... ...colonies and the use of high-density housing systems are also increasing the risk of infection and complicating the ability of veterinarians to detect infectious agents. That’s why veterinarians are very important, to animals and humans according to Bennett, Justin C, animal scientist. With put veterinarian’s many diseases that rodents transmit would be infecting humans. Becoming a veterinarian would be a lot of work. It would take a good few years, and training. However, becoming a veterinarian assistant, and studying to become a veterinarian, can help a lot. I can get work experience, and understand many things faster and easier. Being accepted into veterinarian school seems hard but not impossible. From this paper I learned that I have lots of math and science classes to take. How long it will take to become a veterinarian and what it takes to become one.

For example, if a child was taught to say yes sir while growing up by the time he or she becomes an adult they have developed a habit of responding as yes sir without thinking twice because of saying it repetitively as they grew up, which can appear to be a reflection of a person with good moral character, although that is not always the case in my opinion. In contrast, a person of bad moral character also could have been taught as a child to respond as yes sir as they grew into an adult developing a habit, but overall his or her moral character is bad. In addition everyone agreed that habits, whether morally good or bad is formed from repetitiveness, which does not always result in the person being of bad or good moral character. On the other hand, quite a few classmates disagree on the viewpoint concerning habit and moral character being linked; as some of them argue that the two have no connection what so ever. In contrast, my perspective is that habit and moral character is connected to a certain extent based on the circumstances. For example, habits whether good or bad, are apart of every individuals moral character; I have a bad habit of purchasing shoes, although I do not need them, but I have a urge to purchase a pair or two if I go into shoe store. This is something I have been doing for as long as I can remember, but I must say it has gotten better because I intentionally stay out of the shoe store. Nevertheless, it is apart of who I am, that is, an individual with a shoe fetish, which I actually do not believe to be a bad habit, as most would say the opposite. But, â€Å"Does that make my moral character bad? † Not hardly; therefore I would say my viewpoint and those in opposition to it follows the modern form of ethical thinking because from a modern perspective the act of purchasing one, two, or how ever many pair of shoes repeatedly is not wrong it is something that I have a passion for, and does not result to anyone getting hurt.

101 Reflection and Intro to Report Professor Ramos Blog

101 Reflection and Intro to Report Intro to Report Reflection Reflect on the writing process for your first essay. Answer these questions: What did you do well in your essay? What are the strengths and weaknesses of your essay? Where did you struggle, if at all? Intro to Report Reports are as diverse as all the classes you will take. You can write a report on a lab experiment, conduct interviews and assemble into a report, and even research a topic and publish it for the benefit of everyone. Reports are a genre that you may be familiar with but not know it. Reports are what we have done since elementary school. Reports are produced by government organizations, websites, companies, universities, and even individual students like yourselves. A report can answer a question, explore a topic, review what is already known about a subject, or report new knowledge, to name a few. There are a few qualities that a report usually has: Presents information Uses reliable sources Aims for objectivity Information is clear and well structured For this assignment, I want you to choose a topic that interests you and you want to learn more about. It can be related to your major, future or current career, something you are familiar with, or something you want to know more about. You can research a problem that you want to know more about. We will learn to research the library databases in order to find reliable sources of information. Subgenres of Report The report can be in any style or format that you think best suits it. If you choose to do a PowerPoint, that is your report. You do not need to write a separate report, the PowerPoint should have all the information on it. Here is a list of possible choices: Research Report –What it takes to be a teacher PowerPoint –  Mexican-American Report Wikipedia  style entry Featured Article  in Newspaper Other, cleared by Professor The Conversation We have already learned two important concepts: Literacy Writing Process The third concept is the metaphor of the conversation. What we are studying now, has a long history. People have been writing and researching everything you can think of. For example, the conversation on how to speak well goes back a couple thousand years to Aristotle, Plato, and others that came before. Everything you will write about from now on, needs to be based in a conversation. A scholarly one, a scientific one, a popular one. To know what has been said before, you need to read and research. Entering the Conversation The introduction to the textbook, page 1, explains that the book relies on templates to help us do the basic moves of writing. The templates are guides that when used, help us to structure and generate our own writing. We will talk a lot about approaches to writing and how to think about writing, as well as use the templates provided, to help us practice the principles of writing. It is true, of course, that critical thinking and writing go deeper than any set of linguistic formulas, requiring that you question assumptions, develop strong claims, offer supporting reasons and evidence, consider opposing arguments, and so on. But these deeper habits of thought cannot be put into practice unless you have a language for expressing them in clear, organized ways. (TSIS) State your own ideas as a response to others. You are just entering a conversation that has been going on for thousands of years. You are not expected to know everything, but you are expected to begin to understand what others have said before and how to find it. To argue means more than just stating your own position. To argue you need to enter into a conversation with others views. Then you can try to convince others of your position or just to see your position as valid. Burke’s â€Å"Unending Conversation† Metaphor Kenneth Burke writes: Imagine that you enter a parlor. You come late. When you arrive, others have long preceded you, and they are engaged in a heated discussion, a discussion too heated for them to pause and tell you exactly what it is about. In fact, the discussion had already begun long before any of them got there, so that no one present is qualified to retrace for you all the steps that had gone before. You listen for a while, until you decide that you have caught the tenor of the argument; then you put in your oar. Someone answers; you answer him; another comes to your defense; another aligns himself against you, to either the embarrassment or gratification of your opponent, depending upon the quality of your ally’s assistance. However, the discussion is interminable. The hour grows late, you must depart. And you do depart, with the discussion still vigorously in progress. Conversation and Report How is the conversation connected to a report? Brainstorming Let us brainstorm some ideas. We first need to choose a topic to write about. Build from lists Mapping ideas Freewriting Memory Prompts Search online for ideas Come up with at least two ideas that you want to write about. They can be general now, they will become more focused as you begin the research. Chp 5, â€Å"And Yet† Distinguishing What  You  Say from What  They  Say Chapter 5 (p. 68) introduces you to the term  voice markers  in order to help you distinguish the â€Å"I say† from the â€Å"They say.† This is a very important move since we are now including the â€Å"They say† in your writing. If you do not do this clearly, the reader will be confused as to your position and you may seem to contradict yourself. The templates help you with specific ways of signaling who is saying what, and to embed the voice markers. Being able to distinguish your own view from the common view is a â€Å"sophisticated rhetorical move.† Using â€Å"I† or â€Å"We† The chapter also covers using the first person in academic writing, â€Å"I† or â€Å"we.† You have likely been told to not or never use the I in college writing. The book argues that well-supported arguments are grounded in persuasive reasons and evidence, not in the use of or nonuse of pronouns. Free Write Take the topic you are thinking about researching for your report and write it at the top of a page. For the next five minutes I want you two write down everything you know about it. Do not edit as you write. Just keep writing and see where it takes you. Just keep writing. If you thought runs out, skip a line and start a new thought. Keep writing. Figure out what you know and what you need to research.

A short quiz Essays

A short quiz Essays A short quiz Essay A short quiz Essay In todays society, many are not aware that they fall In a category of personality regarding the self. The more one tries to answer the questions about their self, the more one beings looking further Into their self. From Walker Percy essay, A Short Quiz, the following paragraphs will include explanations of three of Perrys selves: the cosmological self, the role-taking self, and the scientific and artistic self. The cosmological self can be identified as one of the most common selves in todays youth. The self is either conscious of itself or only conscious of itself insofar s its identity with a cosmological myth or a classificatory system (14). In public media, many artist make appearances which leave a large Impact on people. Such include, first, Justine Bibber. He began singing In the corner of streets to catch the attention of those who walked by and ended up selling millions of records by the side of many other famous musical artists. Through the journey of finding his self, he brought along his fellow believers, or devoted followers. These followers felt as if identifying themselves as a believer, they would receive as well as give some sort of raise or recognition. Not only does the cosmological self apply to one person, but It also applies to a group of people. Take the Dodgers for example. The Dodgers are primarily famous throughout the Hispanic communities but also in California itself since that team has been placed there. As commuters are driving down the freeways in California, they are most likely to drive by a billboard with three large words printed across, Live, Breathe, Blue. Automatically, the word blue is affiliated with the Dodgers, being that their team color is blue. This billboard contrasts two important incepts, living and breathing, to the the color blue,which as discussed appertains to the Dodgers. The self ls_. _ only conscious of Itself Insofar as Its Identity with A classificatory system (14). In this way, people try to find themselves through the classification of others. And finally, the most common cosmological self, astrological signs. Various question the effect astrological signs have on the readers views of themselves. Astrological signs play a large role in many lives today. In a sense, it helps todays world to find themselves. The key phrase in that sentence Is in a ensue. The reality Is that astrological signs, as well as idols such as Justine Bibber and the Dodgers, are only used to fill up the empty space In ones mind which holds the definition of that persons self. The second of Percy selves is the role-taking self. One sociological view of the self is that the self achieves its identity by taking roles and modeling its own from the roles of others (15). A natural example of this is the relationship between a child and their parent. A childs first words generally originate from their parents speech. A arena may consistently ask the child If they want milk, a toy, or even their father. This occasionally results in the development of a childs first word. As a teenager, they begin to acquire some habits, good and bad, from their parents. This includes speech, organization, and work habits. As an adult, they may choose to raise their child in accordance to their parents early decisions. In all, a child imitating their parent Is typical in the role-taking self. A contrasting bond may take place in an employee to trainer setting. As there is no natural, or blood, relation In this type of mains the same. And finally, the role-taking self between a player and their coach. Not many people have the opportunity to experience the relationship between a player and their coach. It is what is commonly known as a love/hate relationship. The day a player win their match, race, or game, they are in love with their coach. But that love never last longer than two days when that player is back on the field or court wishing they had left the scene when they had the chance. Despite the adversities present in the role-taking self, it provides a template which one can always rely on. The third and final of Perrys selves is the scientific and artistic self. That self which is so totally absorbed in the pursuit of art or science as to be selfless. (16) To be selfless is to be concerned more with the needs and wishes of others than with ones own. (ODD) There are two famous modern artists who fall into this category. The first is Stefan Joanne Germantown, openly known as Lady Gaga. She was rejected ma ny times before finally getting signed on a record deal which eventually led her to her millions. Her selfless led her to this point. She never gave up on herself because he knew that her music would change the lives of many. The second artist is without a doubt Mile Cyrus. In the pursuit of art, she has completely and utterly changed her whole lifestyle. She went from holding teddy bears and dreaming of rainbows to wearing teddy bears and visualizing rainbows. And last but not least the world famous Albert Einstein. His persistence can truly be marked as a perfect example for anyone fighting for what they know is right. Despite all the attempts to put him down and shut him up, Einstein continued to humbly research and discover wonders of the roll while locals roared about his obvious differences to normal society. True selflessness can be learned from the examples of Albert Einstein as well as Lady Gaga and Mile Cyrus in the scientific and artistic self. Muff have spent a lifetime with yourself, live in the century of the Self, and therefore ought to know yourself best of all (12). In his essay, Percy mentions that anyone can explore for their true self but no one will find it. The cosmological self, the role-taking self, and the scientific and artistic self all reflect Walker Perrys ideas on how people live and act in todays culture.
