Finding Home in Food - Essay Example This research will begin with the statement that since his teenage years, Western food has been a source of great attraction and enjoyment to the author. Fast food like burger and pizza had become his favorite since his teenage days. Eating pizza was one of the most pleasurable activities in his young days. The researcher has remembered going to a pizza joint near his school every weekend. Although it was not considered good by his family to have fast food, he used to love it. The author was discouraged from going to these joints. However, he used to manage going there with his friends on weekends. The researcher’s memories are filled with the fun and enjoyment that he has had while going to the fast food joints. He loved the cheese, different toppings and the starters that were all made in a Western way. Going to pizza joints made him feel that he was ‘modern’ in his outlook. For the author, eating fast food was like being a part of the ‘developed’ w orld. He used to look forward to going to pizza joints and enjoy the pizzas. So when the researcher got a chance to travel to the United States, he thought that he was going to have the greatest time in his life. The author knew that it is the country where burgers and pizzas are found in great varieties and sizes. Moreover, there was no one to stop him from having it. So he thought that his time in the USA will be filled with great entertainment and fun. The author thought that he will not miss his home much. However, his journey to the United States proved his thinking completely wrong.... I had thought that fast food is one thing that I cannot live without. Soon I realized that I was wrong. By the fifth day, I started remembering home food. My mind started dwelling on home made food and beverages. On that day, I told my friends that I will order the pizza. I took the number for nearby pizza joint and called them. I went outside my room to avoid my friends from listening to me. When I became sure that no one was listening, I asked the guy on the other end, â€Å"Do you have pizzas with Asian toppings?† The customer care guy gave a long â€Å"mmmmmmm† and said â€Å"No sir, we don’t.† I was quite disappointed and ordered the usual pizza. By this time, i.e. in just five to six days from the time I arrived, I had lost my enthusiasm towards fast food. I was craving for spices and variety in food. Even then I thought that maybe I am feeling home sick and hence, missing the food. I thought that if I have just one dish of Asian food, I will go back to the fast food with the same enthusiasm. However, my heart was saying something else. Fortunately, the confusion between the mind and the heart was cleared very soon. The next day, one of my distant relatives came to visit me. She brought a big Tiffin box full of Biryani, an Asian dish made of rice, chicken and spices, for me and my friends. She said she thought that home made food will make me feel at home. I said it is nothing like that, and that I am quite used to the Western food. My friends coughed to hide their laughter. After all, there was no strength in my statement. They had realized that I was craving for home made food now. However, as I did not want to lose the challenge, I tried my best to hide the truth.

Taking Risks - Essay Example bullies, praying hard and asking for divine intervention so that I could pass the tests and achieve passing marks in classes that I knew I was going to fail due its difficulty, wishing that things would get better for my personal life and asking for the guidance of the spirit in order to see where my path truly lay... these were things that I was told should be left up to my faith to solve. Yet no solutions came my way. Life did not get better. It seemed to just continue to get worse. Until one day, I decided to take charge of my life and throw out my religious beliefs. I said â€Å"I am in charge of my destiny, I will create my own path†. Guess what? Life got better. I took charge of my future and chartered the path I wished to take. The improvements were remarkable. All leading me to question what exactly religious belief is for. All religion does is sell a person of bag of goods, then leaves you holding an empty bag. Life has nothing to do with religion. Religion has no influence over a persons life. That is how what I used to believe was finally changed into something that I continue to question to this very

Socail processes and practices on identity development Essay

Socail processes and practices on identity development - Essay Example 2002, pp. 359-378). Social processes and practices consider disability to result from disabled persons as an oppressed group and restrictions. This paper critically evaluates and examines social processes and practices on the development of identity. Impairment encompasses a functional limitation produced by deficiency. On the other hand, disability includes all exclusions due to social or physical barriers and it incorporates persons in other socially excluded groups such as ethnic minorities, poor persons, and women. Individual and collective identities remain determined by motivational, cognitive, and social processes and practices. The orientation of social dominance centers on the degree to which a group or person would wish and support a group’s hierarchy, along with the dominance of superior social groups over inferior groups. In addition, the impact of social processes and practices would be moderated by identity. Contextual practices or situational processes would not affect gender differences in orientation of social dominance (Guimond et al. 2003, pp. 697-712). The orientation of social dominance mediates the relationship between attitudes towards identity and social processes or practices in the framework of a subjective classification system set or self-selection. In addition to self-selection, the impact of the social processes and practices causes significant changes in beliefs and attitudes in several ways conditional on the situational context of the personality model. On the other hand, the outcomes of a social group model indicate that the acquisition of dominant identity remains significant to the socialization process. This change could also be attributed to cognitive psychology, as individuals would want to justify their identity in social activities. Hence, in establishing the identity of a disabled person, it would be

Evaluation Speech Self - Essay Example 4. The speaker needs to work on adding variety his speech patterns more, placing emphasis and stress on the important points he wants to convey. He should add variations in tone and volume, and support with the appropriate gestures. 1. Gabrielle tries to make a strong opening also, but comes across as a bit self-conscious and shy, and this is further underscored by her gestures which are rather frequent and nervous. The beginning is not effective in capturing the audience’s attention. 2. The speech is poorly organized. Her topics are not well-structured. She tended to repeat some things, such as the fact that she wants to help people. She also tended to jump from one point to the next and back again, as in alternating between events in her life (her course, what she wants to take up) interspersed with comments about her personal inclinations, then back again. The topics are not quite ordered in a logical sequence. There don’t appear to be three main points in her speech, but if there are three main points, they would be her aspiration about what she wants to do, her independence from her parents’ decisions, and the fact that she is aspiring to be a doctor in order to fulfil her desire to help others. The topics are not well delineated, however, as she tends to move among them alternatively. 3. The speaker is more animated in her tone, pitch, volume, and so forth, and tries to relate to her audience by maintaining eye contact with them. However, she fails to establish eye contact with the webcam as specified in the instruction. She tries to avoid note card dependence, putting it down at times and trying not to look at it, but then she picks it up again and looks again at it. 4. Gabrielle should not be too nervous, as she conveys this by her seeming desire to be conversational in her approach, and

Windows File Systems Essay Example | Topics and Well Written Essays - 500 words

Windows File Systems - Essay Example This file system was developed to improve on the features that lacked in the FAT 32 file system. The file system was incorporated with features that would allow for enhancing the stability of the versions of Microsoft windows. FAT is another file system that is used by different versions of Microsoft windows. These file systems compares in that, they can be used with the latest versions of Microsoft windows, which are beyond windows 95A, 3X and 7.1 window versions, which can not apply the earlier file systems of FAT 16 (Mendel, 38). Another comparison is in the fact that these file systems allows for the formatting of hard drives with a size beyond 2GB as a single partition. Further, a comparison of these file system is in the fact that they help in avoiding the loss of hard disk space, in form of slack. A feature that these file systems possess in common is that they are all compatible with the windows XP version of Microsoft windows (Carrier, 22). However, there is a contrast among theses file systems. To start with, while the FAT file system can be used with all versions of the Microsoft windows, it is not the case for the FAT 32 and the NFTS file systems. FAT 32-file system is limited to few versions of these windows such as windows95, windows 98, windows XP, and windows 2000. On the other hand, NFTS file system is limited to application with some versions of Microsoft windows such as windows XP, windows 2000 and windows 4NT, while applied with service pack 4 (Mendel, 54). Another contrast as depicted by theses file systems is that, the NFTS file system is more powerful as compared to the other two file systems, and contains with it features that enables it to host active directory, while at the same time possessing security features that are domain based (Carrier, 36). Another contrast is that, while NFTS file system allows for the creation of limited access accounts, which limits the files and the folders that some indivi duals can access in a

Environmental pragmatism Essay Example for Free

Environmental pragmatism Essay Pluralism, environmental pragmatism and eco feminism represent differing perspectives on the subject of moral ethics. The paper seeks to look into the details surrounding some of these issues and comparisons between them will be made. Major principles As the name suggests, eco-feminism refers to a merger between feminism and environmentalism. In other words, the term refers to a social movement that connects female oppression and the degradation of nature to similar attitudes that are related to masculine domination. The latter principle asserts that there must be some sort of interrelation between women, race, class and the environment. While the oppression of women may be the main concern within this field of study, eco feminism asserts that environmentalism, animal rights, class struggles, age oppressions, human supremacism and racism all have one thing in common; they all signify oppression driven by the same social mentality. (Thoma-Slayter Rocheleau, 1995) One of the most interesting aspects about eco feminism is that this particular movement has merged thoughts and views in seemingly different fields to come up with a comprehensive analysis of current environmental problems. Eco feminists assert that male land ownership has led to patriarchy hence resulting in a manifestation of the following environmental problems †¢ Viewing animals and land as material resources †¢ Abusing land †¢ Exploiting people †¢ Overgrazing †¢ Excessive food export even when local residents lack adequate food The latter adherents also propose that this abuse of land and environmental degradation has eventually led to female oppression. Such an assertion was made by Thoma-Slayter, B. Rocheleau, D. (1995) in their book â€Å"Gender, Environment and Development in Kenya† McMillan. The latter authors illustrated how exports in this East African country have been driven by a capitalist culture that has led to soil erosion, deforestation, excessive pesticide use and less productive land. In the end, families have been forced to move from such areas and this is especially visible among the women. Other authors claim that the reason why nature has been undergoing excessive degradation is because nature has been treated as something that is only valuable if it has material benefits. Again, such proponents claim that this is the same view held about women; that they have little value since they are not the major wealth creators. However, eco-feminists assert that such beliefs are quite misleading owing to the fact that nature is still useful even without man’s interference. An example of such a perspective is when one analyzes a forest. The former attitude would assume that a forest is useful for fuel, food and the like. However, even without tampering with it, a forest can still be useful in terms of protecting ground water, circulating oxygen or providing a habitat for other animals. On the other hand environmental pragmatism is founded on the beliefs held within pragmatism; that there is no absolute truth in the process of seeking for knowledge. Instead, pragmatists assert that there are only relatively stable ones that assist people in the process of making sense of their world and their surrounding. Experience plays a central role in pragmatism because through it one can either affirm or reject previously held beliefs about how their world works. Given this background, then it is possible to understand some of the perspectives put forward by environmental pragmatists. The latter school of thought put forward the idea that the environment forms a central part of our experiences. Consequently, it needs to be held in high regard. It asserts that every part of the environment needs to be treated with as much seriousness as the next. For instance, oceans are jut as important as deserts or just as important as buildings and bridges. (Lucas, 2002) Environmental pragmatism rejects the notion that man can dominate the earth. Since nature is an important part of one’s experience, then it is essential for man to look for the most feasible ways of co-existing with nature. In fact, adherents to this philosophy claim that understanding or cultivating meaning in the earth is quite crucial, however, imagining that man can do anything with nature without dealing with any consequences is self defeating. Additionally, the latter adherents put forward the notion that exerting care within the environment is a crucial element in preserving it. They claim that in the process of determining what constitutes good things or what constitutes right things, it is indeed necessary for human beings to implement environmental ethics through the foundations of certain beliefs and ideas. One can therefore assert that environmental pragmatism has elements of interrelatedness with other concepts. In this regard, there is a connection between eco feminism and environmental pragmatism owing to the fact it refers to the concept of caring for one’s environment. Environmental pragmatism also brings in new concepts of environmental philosophy owing to the fact that it opposes the notion of trying to decide constituents of value. In other words, the latter adherents claim that it is impossible to determine whether man holds greater precedence over nature. Instead, both issues need not be treated as mutually exclusive as they both need one another. (Lucas, 2002) Pluralism on the other hand refers to the acceptance of diversity of thought within ethical endorsements. Adherents to this school of thought claim that it is possible for different perspectives to exist within a particular ethical system owing to the fact that morality is an ensemble of many things. This means that nature as it is cannot provide an underlying and thoroughly conclusive explanation for things; consequently, it is best to settle for a series of explanations that can provide a more comprehensive framework for these matters. In this regard, pluralism can be related to eco feminism owing to the fact that the latter theory attempts to merge concepts from different fields. Additionally, environmental pragmatism is another form of pluralism because in the former philosophy, there is the belief that there is more than one way to understand nature. Pluralism can occur in three forms i.e. †¢ First order †¢ Second order †¢ Third order In first order pluralism, environmentalists believe that the value in something can be described in more than one way i. e. beauty, diversity etc. In second order pluralism, there is the belief that nature can be described in so many ways that there is no single method that is appropriate. In third order pluralism, there is the belief that other views should be tolerated because it is almost impossible to account for forms of value within nature. In this regard, pluralism advocates for an overlap of explanations. (Lucas, 2002) Conclusion Eco feminism is the view that falls in line with my belief system owing to the fact that it is the most practically rooted environmental theory. Additionally, its interrelatedness with other concepts is less abstract than in pluralism or environmental pragmatism. The latter two theories are quite related because of their adherence to multiplicity of beliefs. References Lucas, P.

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.
