Environmental Law - Essay Example The term ‘takings’ has significant role in the environmental law as the term elucidates that those species who are catalogued endangered under the provision of ESA are protected and it does not allow individuals to harm them or take them along. The ‘taking’ terminology suggests that taking those species away. The harming issue has been remained under the great debate that either under the ESA acts harming is allowed or not. Several law cases have been filed and culprits got away from them as they came under the harming category. This process carried till 1999, when finally ESA came with the clear cut definition of harming and declared it as an essential part of the act too. According to the new provision of ESA 1999, any individual found harming the species would have to face the law (Steven 58). There are serious punishments regulated in case of ESA violations. Great amount of $50,000 and a year in prison are the highest amount of penalty to the culprit. Th e renowned takings law case of Great Oregon v. Babbitt 1994 is one of the major examples of the cases that were resolved by the Supreme Court. The case arose on the issue of harming species and invalidation of ESA takings. The appeal was done by Sweet Home regarding this matter. The case went through prior consideration of the court and collected all the relevant evidence in this regard. Upon inspection and examination of circumstances rampant, the court concluded that actually killings and injuries of rare species took place which is a violation of ESA. At that time specific definition of ‘harm’ was not given by ESA and ambiguity on this matter remained, but U.S Supreme Court made things crystal clear by giving this important historic ruling (Steven 74-85). Success and Failure of NEPA The National Environmental Policy Act NEPA is one of the most important established environmental laws of the United States. The main agenda of NEPA is to safe, preserve and conserve spec ies prevailing everywhere in the country. The protection of environment is foremost important task of NEPA. The inauguration of NEPA has been criticized significantly all over the United States as its implications and application is not considered resourceful and powerful in the country. There are numerous success and failure stories of NEPA. The involvement of people in NEPA programs is tremendous. The awareness element has been established among the people and people have started to take it very seriously. By the help of volunteers, awareness measures among regions have been started too. The outcomes achieved till date present a promising picture (Vallero 67). The Forest Service funded Vegetation Management Project was launched successfully by NEPA so that issues regarding the forest health would be eradicated. The vegetation concerns were also present in Crooked River which was addressed by the implementation of this project. The Rural Development Community Facilities Program pro posed that building of hostel for students would be beneficiary for individuals and college too. NEPA took over this proposal and built the apartments in order to facilitate students. NEPA has been providing services to the defence sector of the United States too. Their services are highly regarded as they made precise plans for the successful inauguration of defence endeavours. The Energy Conservation

Indigenous Tradition Essay Example for Free

Indigenous Tradition Essay In the past people have mistaken about their tradition Indigenous originality or occurring naturally (country, region etc) To be indigenous kinship (relation to one another) and location(connection of particular place) Indigenous religion beliefs, experience and practices concerning non-falsifiable realities of people who have kinship and location Syncretism: Syncretism merging of elements from different religions. Eg : north American tradition have been influenced by Christianity, some African rituals are influences by Islam. * Change occurs everywhere. * Traditions are less authentic (accurate) than thousands year ago Indigenous can be found anywhere: * Anishinaubae: drumming ceremony in Toronto * Yoruba: Funeral rites in London * Maori: Purification ritual in opera house Sydney Australia Misconceptions * Common to Indigenous traditions is colonialism * Oglala (Indigenous community) – a theorist explained them as â€Å"warriors without weapons basically they were incapable to adapting a new economy lifestyle they focused on how to make them â€Å"modern Indians† * Outsider lack insider knowledge. * Scholars often used terms such as fetish, myth, mana, taboo to explain Indigenous traditions. * Eg â€Å" Indigenous stories are called myth where the bible is considered to be true. Primitive Cultures that are unchanged from the beginning primitive Christians, who believed in god and their tradition, had superiority and began to spread their religion to who didn’t know about gospel Indigenous traditions are tend to think more primitive Due to non-literate * But writing to not better than oral speaking * Mayan did use writing * Most Indigenous people are very literate. Indigenous tradition are tend to think more primitive – consider everything to be sacred (untrue) * Eg : Navajo : ceremony that transforms normal house into a scared place. So everything such as eating, sleeping is considered to be sacred. * Australian aborigine knows where to pray(know the difference between sacred and non sacred mountains) Primitive term is now disagreeing by many scoloars Mohawk and Cree (Dr Clare Brant) Mohawk: Indigenous traditions who give more food to their guest to show their wealth. Cree: Indigenous tradition who eat all the food offered to show scarcity. These two traditions did not go well together and this shows that Indigenous traditions are different from each other. Another point is that we see other cultures according to our own cultures. Gender roles: * Male: hunting and warfare * Female: healing and food preparation * Maori carvers were men and weavers were women. Bunu men frow cotton and women turn it into clothes. * Sometimes the roles switch just like other traditions * Usually religions practices are different for men and woman too. Power of speech Oral speaking is very imp for Indigenous traditions things are passed down oraly. Many people think oral primitive (untrue). Both Quran and Bible was passed down orally before written into text Stories : After life : * Kewa: a man finds a tunnel where his dead people wre living together and they gave them many things and asks him not to speak of it. When he goes and tell everyone about the tunnel, he breaks the promise and when he returns the tunnel is gone. * Anishinaubae : young man fiance died, and he go on a journey to find her and when he found her , he returns home heartbroken, keeping his promise. * These stories tell us about importance of relationships tell us about how we should live than about dying Writing stores often â€Å"fixed in time†. Trickster: * Considered as â€Å"culture heroes† because they are the central figures in many stores * Usually shape shift usually into animals * Can change genders sometime biological and sometime just clothes changing * Outer form is reflected into infidelity * They can appear as fools, selfish, kind, scandalous etc. * Usually driven by self interest alone * Trickster stores show us how we should behave and how we should not * The stories often explain the origins of world and connect to a community more deeply. * Embodies the extremes of humanity: human weakness and strength Practice (rituals). Indigenous tradition rituals are very similar to our traditions * Rituals remind us on what is imp in our life. * In religious terms, rituals, communicate some ways with gods, ancestor and spirits. * Rituals are roots in the human needs and relationship Rituals : * Every rituals varies * Usually involves food Muslim and Jews have specific food eating habits * Many Buddhist set food portions aside for ancestors * Anishinaubae put small amount of food for the spirits * Some rituals are more complicated * Such as marriage, death, birth * Sometimes these rituals mark transformation and sometimes they help to bring the transformation about. * Indigenous tradition rituals serve in some ways to recreate some aspects of the world, order and life Journey: * Going on a journey/quest: rites of passage * Journey to a new place is where a transformation occurs. * The person returns home with physical change, such as tattoo, scar or a body part to symbolize their new self. * Pondos: moved into a special hut to become sacred healers- if they go into town before they must be covered in white * White usually symbolize the color of transformation in Africa * Anishinaubae vision quest – yong man travels far away from home only with water and be completely alone. Then late he become a â€Å"adult man† and comes home with food and the ritual is complete . Sacrifice Mel Gibson: sacrifices in Indigenous traditions are vey common Bear sacrifice: raise a young cub, and raise it for two day and kill it. Head is emptied and filled with flowers and then the animal is cooked and eaten. They think that the bear is the gold’s spirit and they see it as freeing the spirit. Sun dance : dance till days and community provide support. Some sun dance involves sacrifice . the pole and lodge are buil to show the creation of the world Nuer : sacrifice ox for healing. Xhosa : when a woman fall ill the community gathers and kill a cow and do many rituals. This is due their thinking that the ancestor or spirit is angry with the women. * above rituals shows the involvement of community even though there is sacrifice involved. * The rituals ultimately brings people together * Sacrifice like rituals create order and meaning * Those rituals join people to the past and respond to current situation Cultural Expression What you see is not always what you get Art in Indigenous traditions is aout relationship objects are coonected to people Weaving : * Intertwine and connect * Weavers work together , helping one another , passing knowledge. * Shows bonds among people Maori Tradition : * All weavers are female * A girl is said all about weaving more said more discouraged if people saw true commitment then they let the girl into whare pora(caretakers of the weaving) * Whare pora have rules no sex before dying, no food allowed during weaving, special garment should be weaved during the day and not strangets can view the weaving * Traditional colors : black, red and white * Sacred thread is sewed on all garments to show the bond Underlying cloth : * Clothing declare who we are and how we fit into social fabric * Has two side : can hide much as it reveals and help us create a public face * Lady gaga : he masks and clothes hide part of her but also reveals her identity that she wishes to show * Special clothes are associated with imp rituals * Bunu : believes that the special clothes are kind of womb, enveloping the body as like a fetus is being born. Clothing only wears it does not die old cloth is replaces by new, as old spirits is reborn Spirit basket : * Oldest arts * In pomo community men makes the heavy basket for hunting and fishing * Women were responsible for religious baskets. * Mable mckey : was a traditional healer in pomo community and famous basket weaver in the world. Masks : * Masks are used in imp rituals wedding , funerals, hunting celebration etc * Masks are ment to ring spirit into the community lesser deities (gods) * Mask represent certain animals does not mean they worship the animal * Epa mask in Yoruba community extremely heavy show the strength require to dance with the mask and enter the adult hood with responsibility. * Carvers are usualy male Totem poles : * Very specific to each communities * Function of totem poles also varies in each tradition. * Meaning varies serve as a supporting structure or grave makers and other as a symbol for power * Most also tell stories such as historical, achievements and religious * Grizzly bear at the base holding a human represents self-preservation or survival. Moko * Maori carvings are less likely to be displayed outside the original physical context * Moko tattoos * In the beginning the women were only allowed tattoos around their lips and chin where men can have tattoos all over their face * Moko story remind the Maori people their ancestor and importance of meeting ones obligation and treating one another with respect Ancestoral House. * Marae Maori religious and social home.

Home Alarm System: An analysis

Home Alarm System: An analysis Home burglaries and property trespassing is a common event; more than forty per one thousand households get robbed yearly. With the introduction of home alarm systems the rates of burglaries have dropped significantly for the past thirty years. Therefore, throughout the semester, we have been working on building a functional home alarm system using PIC microcontroller, a keypad, an LCD display and a magnetic sensor. Household burglary is defined as an illicit entry or attempted entry of a residence which usually involves theft. The illegal entry may be by force, such as breaking a window or slashing a screen, or may be without force by entering through an unlocked door or an open window. As long as the person entering has no legal right to be present in the structure a burglary has occurred. Furthermore, burglary is not only the entry of the house by itself; illegal entry of a garage or any other structure on the premises also represents household burglary. [12] Figure1.Home Burglary Statistics (2008-2011).Washington Post [Photograph].Retrieved from http://homesecurity.net/home-burglary-statistic/ The most common targets are residential houses. Those of them without security systems installed are about three times as likely to be broken into as homes with security systems installed. Moreover, the first place that the robber will search is usually the master bedroom because most people keep their valuables there. The preferred items to be stolen are cash, jewelry, electronic equipment, silver, guns and other items easy to put on the market. [8] Statistics showed that every 14.6 seconds, a burglary takes place in the United States and most of them occur between 10 am and 3 pm. Burglars spend an average of 8 to 12 minutes in your household. The residence owner can take the following safety measures such as: burglars search for homes that appear to be vacant; robbers want to waste no more than sixty seconds breaking into a home. [8] Points of Entry of Burglars: Figure2 .Burglary Facts and Statistics (2008). [Photograph]. Retrieved from http://www.articlesbase.com/home-and-family-articles/burglary-facts-and-statistics-338161.html One survey in Pennsylvania showed that: 81 percent of residential intrusions occur through the first floor. 34 percent of burglars entered through the front door; 23 percent through a first-floor window; 22 percent through the back door; 9 percent through the garage; 4 percent entered through a basement; 4 percent through an unlocked entrance; 2 percent through a storage area; 2 percent entered anywhere on the second floor. [2] Definition of a Home Alarm System: A home alarm system is used as a defensive device to monitor all unwelcome events such as intrusion, glass breaking and mainly to avoid theft. It is also used to alert a user of a possible danger. It focuses on all of the accessible entry points of the house, so that the alarm will sound as soon as the intruder enters. Advantages: The most important advantage of the home alarm system is the security it offers from theft of costly things such as the jewelry, the television set, your pc, cell phones, and etcà ¢Ã¢â€š ¬Ã‚ ¦ causing massive financial problems. In addition, a home alarm system is necessary not just for the material possessions in your home but also increases protection on the family. Furthermore, a burglar may want to break the door of your house while barging in. You also might have to cope with broken windows, smashed furniture and other general damage. Making up for this damage will be expensive not just time wise but also requires great deal of effort since burglars these days are interested in expensive items. They search for important identifications such as your bank statements, passports, and credit cards, essentially whatever they get their hands on. The misuse of these documents will disturb your economic balance. [13] Therefore, it is recommended to install a home alarm system at your pl ace. Disadvantages: One of the main disadvantages and is mainly caused by a malfunction is the generation of a false alarm where it can be triggered accidentally and thus cause unnecessary inconvenience. Moreover, having children might cause a lock of the system by improper insertion of the password. Also, if you failed to insert the password in time, the alarm may be triggered. Some burglars are highly experienced and have the knowledge to disable the alarm, the phone lines, and the electricity leaving you helpless in a critical situation. How Does a Home Alarm System Operate? Sensors are the most vital part of the system; they act like the eyes and ears of a home alarm system by monitoring break in points and interior areas. The typical sensors, which are usually two magnets, are generally installed on doors and windows such that one magnet is connected to the door or window and the other is connected to the door or window frame. When the door or window is opened, one magnet is removed from the surrounding area of the other and the sensor registers that the door has been opened. More advanced home alarm systems may also contain vibration sensors to detect when glass has been broken by measuring the vibrations caused by the breakage. Also, many systems use motion sensors that compute the proximity of a rooms walls by producing infrared beams and measuring the time required for them to bounce back; if a beam comes back sooner than expected, it likely bounced off of a person and the sensor registers motion. [4] When the alarm system is installed, each sensor is registered with the control panel either through wires or wirelessly. The control panel also interfaces with keypads and other input devices used by the home owner to control the system. The control center keeps track of the status of the sensors and reports activity through LCD displays and other output devices. Moreover, when activity takes places, such as the opening of a window, the sensors report the activity to the control center and the center registers that a disturbance has occurred. In managed alarm systems, the control panel also checks the sensors to verify that they are still operational; if a sensor fails to reply, the center alerts the home owner of an out of order sensor. If the home owner activates the alarm system and the control center registers activity in the home, a signal is sent by the control to a buzzer, flashing lights or any other audiovisual alarm element. Types of Alarm Systems: Home burglar alarms normally include the following: Window and door sensors Motion detectors Main control panel Centrally located keypad Exterior security signs Hard-wired or wireless construction These systems are often centrally monitored by a security provider that alerts authorities of break-ins. Some of the more common systems that are included in many homes: Smoke alarm systems include smoke detectors, possibly strobe lights and hearing impaired features for seniors and hearing impaired home owners. Fire alarms include a series of smoke detectors, heat detectors and possibly an in-home sprinkler. One ignored aspect of your home security is your homes built in systems, such as heating and cooling and plumbing. Critical System Alarms include: Cooling and heating alarms have detection and monitoring devices that transmit information about your heating and cooling system often directly to a monitoring company. Flood and water alarm systems monitor your plumbing system where even small leaks can go unnoticed and result in thousands of dollars in repairs. [5] Types of Alarm Sensors: Alarm Sensors are essential elements of your home security system. A wide variety of security alarm sensors and detectors are available for use. It is obvious what most sensors do, so we will only describe the main ones used in a basic system. Contact Sensors: Most burglaries involve doors, either on entry or while leaving the house. So protecting all doors is a must. (Example: magnetic circuit breakers).Door contacts may be hardwired or wireless; hardwired contacts are usually buried in the doorframe, which is less obvious than wireless and are preferable. Window Contacts: Can be hardwired or wireless. Motion Sensors: Its the most essential and common form of protection. Passive infrared sensors: Detect motion by sensing a sudden change in heat. Dual-Tech motion detectors use two different technologies in the same unit: passive infrared and microwave. These devices are designed to avoid false alarms since both technologies must detect motion before setting off the alarm. Photoelectric Sensors: These sensors project a beam of light across a hall or doorway to detect motion and are triggered when a person passing through interrupts the beam. Glass Break Detectors: Usually mounted near windows to detect the specific high frequency sound of glass being shattered. They are usually installed on a wall opposite or adjacent to the protected glass and are effective within about 15 to 25. Smoke and Heat Detectors: Detect smoke and heat. [1] Chapter II: Our Home Alarm System Our Home Alarm System: Our projects main concern was to build a Home Alarm System using a PIC microcontroller. We started off our project by coding the Keypad, then LCD and the final touch was the sensor. We also added two types of buzzers: one to sound the alarm and the other as a key tone buzzer. The final result turned out to be the following: Figure3. Our Home Alarm System Materials Used: Cost: PIC16F877A 7$ 4X4 Keypad 2$ JHD 162A LCD 6$ 6V Alarm Buzzer 0.5$ Key tone Buzzer 0.5$ 4 MEGA Crystal Oscillator 5$ 3 Flashing LEDs 0.1$ 9 Resistors (10Kà ¢Ã¢â‚¬Å¾Ã‚ ¦, 470 à ¢Ã¢â‚¬Å¾Ã‚ ¦, 1Kà ¢Ã¢â‚¬Å¾Ã‚ ¦) 0.1$ 18 Pico Capacitors 1$ Magnetic Sensor 2$ Input Voltage Wires 0.1$ Breadboard 3$ Total Cost: 27.3$ Process of Building: First of all the PIC: PIC is a family of Harvard architecture microcontrollers. The name PIC refers to Peripheral Interface Controller. They are popular with both professional developers and hobbyists alike due to their low cost, wide availability and large user base. The PIC has an overall of 40 pins. These pins include input/output ports such as PORTA, PORTB, PORTC, PORTD, PORTE and two Vdd ports for input voltage. The PIC architecture is characterized by its multiple attributes: Separate code and data spaces (Harvard architecture). A small number of fixed length instructions. Most instructions are single cycle execution, with one delay cycle on branches and skips. All RAM locations function as registers as both source and destination of math and other functions. A hardware stack for storing return addresses. Data space mapped CPU, port, and peripheral registers. The program counter is also mapped into the data space and writable. There is no distinction between memory space and register space because the RAM serves the job of both memory and registers, and it is usually just referred to as the register file. The keypad: This device is used to enter the password selected by the user and to arm or disarm the alarm by selecting the various profiles installed in the system. As you can see from our projects picture we used a 4 x 4 keypad, as instructed by Dr. Ayoubi we started off our project by working on the keypad and testing it on Proteus and on the PIC itself. The design of a 4 x 4 keypad can be approached by either adopting the serial or the parallel concept. The serial concept is tedious in terms of software effort, complex in circuitry and slow in response. However, it requires few interface lines. Meanwhile, the parallel concept on the other hand is less complex in circuitry, less software intensive and faster in response. Its concept also requires more interface lines, that is, 8 plus an interrupt line for a 4 by 4 keypad. [10] Our design for a functional keypad was the usage of an alternation of ports between inputs and outputs which is done by using the TRIS function. We started off by setting the first four ports of PORTB as the inputs and the latter four ports as the outputs. This is done by moving the binary literal 11110000 to the working registers and having the latter four ports pulled down by 10kà ¢Ã¢â‚¬Å¾Ã‚ ¦ resistors. The first four ports are connected to the columns meanwhile the last four are connected to the rows. Moreover, as a justification for this reasoning is the fact that it is required to scan the columns for the pressed key and then scan the rows and the results will be decoded in a decoder telling us which button of the keypad was pressed. The main functionality of the keypad as mentioned earlier is to set the code. The alarm can be armed and disarmed with a standard four digit user code in our case. The master code is a step above a regular user code. It is used to unlock the system, as well as programming or erasing a regular user code. Theoretically it can also be used to bypass some sensors. The default password set during the design, which is also the installation code, is 1234. Most alarm companies use the same installer code for all of their installations, and the vast majority will never give their installer code to a customer, for obvious reasons. LCD (Liquid Crystal Display): An LCD is a thin, flat electronic visual display that uses the light modulating properties of liquid crystals (LCs). They are used in a wide range of applications, including computer monitors, television, instrument panels, etc. They are common in consumer devices such as clocks, watches, calculators, and telephones. Liquid crystal displays (LCDs) offer several advantages over traditional cathode ray tube displays that make them ideal for several applications. Of course, LCDs are flat, and they use only a fraction of the power required by CRTs. They are easier to read and more pleasant to work with for long periods of time than most ordinary video monitors. It also has few disadvantages, such as limited view angle, brightness, and contrast, not to mention high manufacturing cost. As research continues, these limitations are slowly becoming less significant. [6] [11] [14] In our design, we used a 1k resistor to set the contrast at the LCD display. Sensor Used: The sensor used is the typical magnetic switch circuit breaker as shown in the figure below: Figure4. How Burglar Alarms Work. Retrieved from http://home.howstuffworks.com/home-improvement/household-safety/security/burglar-alarm1.html A magnetic sensor is used to detect any changes as well as disturbances in a certain magnetic fields. In addition, when the magnets are separated it means we have an open circuit and when it is closed it acts like a short circuit. When the door is closed, the magnet pulls the metal switch close so the circuit is complete. Then, the current powers the relays electromagnet, so the buzzer circuit stays open. When you move the magnet by opening the door, the spring snaps the switch back into the open position. This cuts off the current and closes the relay, sounding the alarm. [7] Functionality of our system As soon as we connect the 5V power source the alarm greets us with a welcome message displayed on the LCD then asks us to provide the password. Once entered correctly the green LED flashes accepting the code. If the password entered was incorrect the red LED flashes and the system gives you two further chances to enter the correct password. If both remaining attempts failed the system will lock. The only way to unlock the system is by clicking the star key (*) for more than five seconds. This feature should be kept a secret between the user and the company otherwise anyone who knows it can unlock the system and keep trying to hack into it. The keypad should be installed next to the entry door because it is programmed with a time lag, to permit you to exit when leaving, and enter on arriving home, without activating the alarm. We have set a profile that gives you 20 seconds before leaving the house and the alarm starting. By clicking the (A) button on the keypad the counter starts giving you the amount of time to leave the house. If the magnets of the magnetic switch get separated, by the opening of a door or a window (depending on where it is installed), the internal invisible counter gives the user 15 seconds or 3 trials to set the password correctly or the alarm will go off. The alarm will remain firing until the password is set correctly. Furthermore, the option of changing the password is also available. In order to do so insert an incorrect password and the red LED flashes. While it is blinking click on the star button and wait until the yellow LED blinks and the LCD displays INSERT ADMIN PASS. In our system the administrator password is 5678. After inserting the correct administrator password the system will ask you to insert the new password then once again for confirmation. The administrator password however cannot be changed unless we change it in the code and download it again on the chip. Chapter III: Algorithm Design Block Diagrams: Figure5. Block Diagram showing how the system functions Figure6. Block Diagram showing how the keypad functions Proteus: Figure7. Our Design on Proteus Chapter IV: Conclusion References Conclusion: As we have seen in the graph Burglary rates figure7, the alarm system is becoming a must in modern day life in order to protect our valuables and the ones we care about. As we can see from the graph below, the rate of burglary is declining in 1981 that is when technology started evolving greatly and as we can see with time crime kept on decreasing.

Thomas Jeffersons Contribution to the Constitution Essay -- essays pap

Thomas Jeffersons Contribution to the Constitution The purpose of this paper is to give a brief chronological accounting of the writing of the Declaration of Independence by Thomas Jefferson. A short description of the structure of the Declaration of Independence will be included. The process was relatively fast, from the formation of the committee. The committee consisted of two New England men, John Adams of Massachusetts and Roger Sherman of Connecticut; two men from the Middle Colonies, Benjamin Franklin of Pennsylvania and Robert R. Livingston of New York; and one southerner, Thomas Jefferson of Virginia. In early June, the committee met as a whole and unanimously insisted that Jefferson draw up the declaration. Jefferson wrote that the other members of the committee "unanimously pressed on myself alone to undertake the draught. I consented; I drew it; but before I reported it to the committee I communicated it separately to Dr. Franklin and Mr. Adams requesting their corrections. . . I then wrote a fair copy, reported it to the committee, and from them, unaltered to the Congress." Jefferson's account reflects three stages in the life of the Declaration: the document originally written by Jefferson; the changes to that document made by Franklin and Adams, which resulted in the version that was submitted by the Committee of Five to the Congress; and the version that was eventually adopted. On July 1, 1776, Congress reconvened. The following day, the Lee Resolution for independence was adopted by 12 of the 13 colonies, New York not voting. Immediately afterward, the Congress began to consider the Declaration. Adams and Franklin had made only a few changes before the committee submitted the document. The discussion in Congress resulted in some alterations and deletions, but the basic document remained Jefferson's. The process of revision continued through all of July 3 and into the late afternoon of July 4. Then, at last, church bells including Paul Revere's bell, rang out over Philadelphia; the Declaration had been officially adopted. The Declaration of Independence is made up of five distinct parts: the introduction; the preamble; the body, which can be divided into two sections; and a conclusion. The introduction states that this document will "declare" the "causes" that have made it necessary for the American colonies to leave the B... .... Because of his absence in Europe, Jefferson had no direct part in the framing or ratification of the Constitution of the United States. The most notable achievement of Jefferson's first term as President (1800) was the purchase in 1803 of Louisiana from France for 15 million dollars. (see Lewis and Clark). During his second term Jefferson encountered greater difficulties. One of the domestic problems was the Burr-Conspiracy, with the former vice president on trial for treason. Jefferson was succeeded as president in 1809 by James Madison. During the last 17 years of his life, Jefferson remained in Virginia. As the 'Sage of Monticello' he engaged in a rich correspondence with John Adams and others. Jefferson's last great public service was the founding of the University of Virginia in 1819. He died at Monticello on July 4, 1826 on the 50th anniversary of the Declaration of Independence.

Gender Roles Essay -- Female Male Compare Socialization Essays

Gender Roles   Ã‚  Ã‚  Ã‚  Ã‚  While I was growing up, gender roles were highly defined by my parents and teachers as well as all other societal influences. Boys were taught to do 'boy' things and girls were taught to do 'girly' things. The toys that children play with and the activities that are encouraged by adults demonstrate the influence of gender roles on today's youth.   Ã‚     Ã‚  Ã‚  In my formative years, the masculine traits that I learned came out because of the activities that my parents had me engage in and the things that they expected from me. The expectations that my parents held for my sister, on the other hand, varied from those that they had for me, and this was made apparent through the different activities that occupied her time. My parents treated us in completely different regard. We had different toys, different friends, and we were supposed to like different things. When I got hurt my parents would say things like 'shake it off,' or 'that didn't hurt that much,' but when my sister would cry, they would give her attention and pull her aside to take care of her. I got into a lot more trouble throughout my life than my sister and this was, in part, overlooked as the boy's mischievous nature. I played with GI Joes and He-Man action figures, while my sister played with Barbie Dolls. I remember when she and I would play together and the GI Joes would be married to the Barbie Dolls. When I made the action figures fight over the Barbie Dolls, my sister would always get ...

Finally, lack of funding can be an issue for any airline. â€Å"Smart Ways Airlines† has smart ways to hand funding barriers. One way is by lowering ticket prices and encouraging more people to fly. More people flying at lower rates can actually increase sales than less people flying at higher rates. â€Å"The plane is now landing. Smart Ways Airlines hopes that everyone has enjoyed the flight that they have learned a little about how Smart Ways Airlines offers the best, most comfortable, most affordable, and the most unique flying experience available today. Thank you for flying the smart way with Smart Ways Airlines.†
