What Role does Bundle Sheaths Play in C4 Plants Essay

What Role does Bundle Sheaths Play in C4 Plants - Essay Example Bundle sheath cells are the major site of refixation of the CO2 and C4 acid decarboxylation. The mesophyll cells also concentrate the CO2 and send it to the bundle sheath cells. NADP-malic enzyme (NADP-ME) and phosphoenolpyruvate carboxykinase (PCK) are expressed in the bundle sheath cells of the C4 plants. They are the major enzymes responsible for the refixation of the CO2 from the C4 acid. (Nomura et al. 2005). In C4 leaves, each vein is surrounded by a ring of the bundle sheath cells surrounded again by the mesophyll cells. These bundle sheaths have the chloroplasts arranged centrifugally with the large starch granules and unstacked thylakoid membranes. In the bundle sheath cells ribulose-1,5-bis-phosphate carboxylase/oxygenase (Rubisco) enzyme accumulates extensively. The specific enzyme activity can be easily determined by using the non aqueous fractionation techniques and pulse labeling techniques. (Majeran et al. 2005).

Change Management Essay New consultants are hired to help Riordan Manufacturing in creating a processing for monitoring client’s information that would involve all workers to utilize the same client’s administration process. In part one of this project the consultants would require evaluation of the organization’s intranet site and verification of information. This process would help them in creating an improved administration plan which would consist of many components. For example, proposal of a plan to help execute changes during the upcoming year and clarification of the evaluation processes while ensuring the modification plan is completed. In the second part of this project, the consultants will make a reference to a communication tactic for the proposed change and the effect that would potentially have on the organization. The consultants are to come up with a change management plan and a communication plan for Riordan Manufacturing. Section I: Change Management Plan Riordan Manufacturing is an organization that operates on a bureaucratic system. Separate divisions have managers who are reporting to higher up management. However, even these upper managers, eventually, would have to report to the president and CEO of the organization, Dr.  Michael Riordan. The bureaucracy has a system in place that is similar to the matrix system. Riordan Manufacturing divisions consist of people who carry out specific jobs and every division has its own informal systems, which are created by building working relations jointly. Riordan Manufacturing inspires workers to report any problem or issue that they might have directly to their superior. This would encourage every worker to openly deal with the administration, work in a great environment where interactions could be apparent and attitudes can be positive. Worker behavior would improve greatly because of the open door policy and open interaction because they would be able to express their concerns. When workers feel encouraged to express themselves at liberty, it increases the commitment to the organization and job satisfaction. Even though Riordan Manufacturing needs to create new client administration process, it should continue to accept the matrix structure that is currently in place. By creating a new client administration method it would enable everyone to assess the information of all clients. Retaining the existing matrix system would allow them to ontinue on improving team efforts to progress in the completion of the work that is expected of every division of the Riordan Manufacturing organization. Riordan Manufacturing is a plastics manufacturer with over 500 employees and it is headquartered San Jose (California), and has locations in Albany (Georgia), Pontiac (Michigan), and Hangzhou (China). Riordan Manufacturing products comprise plastic products, such as drink cans, custom-made components, as well as fan mechanisms. Their major clientele are auto and plane component, bottle, and appliance manufacturers, as well as a Department of Defense. To ensure that Riordan Manufacturing delivers these products to their clients, they must implement outstanding and positive worker behavior. Worker’s behavior affects they work performance and their reaction to their work environment, their managers, and clients. Riordan’s tradition comprises of fairness, self-confidence, commitment, imaginative and team-work oriented atmosphere, job performance evaluations, incentives, academic assistance, benefits, vacations, day care assistance, as well as the employees compensation insurance. Riordan appears to be a manufacturing organization that is trying to become a first choice for their customer as a plastic component provider. However, as many other organizations, Riordan Manufacturing could experience issues that would need to be addressed and modified. These issues could hinder the organization’s progress and improvement especially in today’s economy. For example, some workers are unable to deal with the changes and they could become reluctant to perform their jobs. Some employees are avoiding changes because of insufficient information on the changes that are being implemented, being taken out of their comfort zone, insecurity, personal views, job security, peer pressure, as well as a lack of confidence. Even though the employees could show resistance to the change managers would help them to deal with the situation and assist them during the transition to ensure that the implemented change becomes efficient. Managers could implement the change by relying information clearly, by being open, recognizing employees concerns, and respecting the employees. Managers should provide support by allowing them to have a face to face meeting in regards to the changes and explain the benefits of the changes by providing additional training. Also, managers must place the reluctant employees with others who are familiar with the changes that are being implemented. This would help the reluctant employees see that the changes would be worthwhile and beneficial to the organization and its advantages, as well as a possibility of their own jobs to become easier. With any change in management systems we will be expecting some resistance as discussed earlier in our presentation. Once the initiative to change is underway and in progress we will analyze the employees’ reaction to the interruption in their daily activates to identify areas that the employees may be having trouble integrating for the first 6 weeks. Allowing employees sufficient time to dissect and troubleshoot some of the unfamiliar process will give them the opportunity to challenge themselves for growth opportunities and additionally allowing them to develop noteworthy questions and concerns that will assist us to tailor the program to their individual needs. Most major changes in initiatives used to improve profitability normally fail due to incorrect guidance and project mismanagement expertise, which we intend to improve with our 12 month program that we call â€Å"Rehab†. Following the first six weeks of introduction the unveiling of our 40 hours of seminars will commence, which will be used to inform employees of how the system is more beneficial to them, and how the Data Management, Business intelligence, and Data Warehousing will be significantly more applicable to the end-user, which will increase their productivity that will additionally benefit the organization’s bottom-line. One key consideration that will be discussed with the employees is their drop in productivity during the first year of the Change Management implementation; we are fully aware that organizations don’t change people change. Using our world renowned process takes time to fully be incorporated in the daily operations; we will be fully engaged onsite with our four member management team, who will be localized and embedded in your organization to assist all employees in-depth with this drop in performance for the duration of our contract. With over 25 years successfully working with companies of various sizes across the business sector, you can trust in our process methods to keep your business moving in a positive direction a while minimizing people risk. Prior to idea of making an improvement to our data management system we would depend on the accuracy of the employees, with the Data management system we will be able to track and monitor everything from Recordkeeping, monitoring, situational monitoring, and performance monitor. The improvements will allow us to do safe guard against violations of right by allowing access to documents externally, use data received to create lessons learned that we can use to train incoming staffers, build a better reputation for our stakeholders by giving them access to necessary information, and last but not least the ability form documents to be tampered will be drastically reduced. We are only looking at a successful change; the idea of failure is not foreseeable. Section II: Communication Plan  The form used to communicate a change to employees is just as important as the change and message in itself. In this case, the appropriate channel of communicating the change to the employees is a meeting with a PowerPoint presentation. The face to face communication will provide an opportunity for the employees to bring up concerns about the change and ask questions. The employees should be encouraged to be comfortable voicing their concerns. The PowerPoint presentation can be presented in order for everyone to see the goals, plans, and details of the change. These channels of communication will provide the employees with the information about the change while the person presenting it can offer reassurance and answers to questions. The group will have a visual to receive the message and the person who is presenting will be able to give face to face discussions regarding concerns and assurances. Potential barriers to communicating this change include the possibility of misinterpretation of some of the information presented, different point of view and expectations among the employees, and assumptions made by employees and presenter. Strategies for overcoming these barriers include the presenter encouraging people to ask questions, clarifying information, anticipating possible questions and asking those questions. The group needs to be comfortable asking questions and should be encouraged to do so. Any misinterpretations need to be clarified. And the person presenting can come up with questions that people will likely ask and bring them up in the discussion to encourage others to be involved in communication.

X Ray Production And Interaction With Matter Engineering Essay

X Ray Production And Interaction With Matter Engineering Essay The x-ray tube is the most important part of the x-ray machine because the tube is where the x-rays are actually produced. The production of x-rays requires a rapidly moving stream of electrons that are suddenly decelerated or stopped. (C., Andy, 2008). Basically this means that when fast-moving electrons slam into a metal object x-rays are produced. (Bushong, 2008, Ch.6 p.101). Inside of the x-ray tube are three main factors that play important roles in x-ray production: 1.) The cathode 2.) The anode 3.) The vacuum The cathode and anode are basically the only components that help in the production of x-rays. The cathode or also known as the fast-moving electrons is a negatively charged electrode that contains a focusing cup and a filament. The focusing cup is made of nickel or molybdenum and nearly surrounds the filament. It is open at one end to allow electrons to flow freely across the tube from the cathode to the anode. (Fauber, 2009, p.15). It has a negative charge, which keeps the electrons emitted from the filament spreading apart. The focusing cups purpose is to focus the stream of fast-moving electrons. The filament is coil of wire (about 2mm diameter and 1 to 2cm long) that emits the electrons when it is heated. When the current through the filament is sufficiently high, the outer-shell electrons of the filament atoms are boiled off and ejected. (Bushong, 2008, Ch.7 p.122). This is also referred to as thermionic emission. The Anode The positively charged electrode of the tube is called the anode. It consists of a stator, rotor, and a target. The stator is an electric motor that turns the rotor at very high speeds. These speeds range from 3,000 to 10,000 revolutions per minute (RPM). The rotor is rigidly connected to the target through the anode stem, causing the target to rotate rapidly during x-ray production. High Strength ball bearings in the rotor allow it to rotate smoothly at high speeds. (Fauber, 2009, p.17). The last component of the anode is the target. The target is the metal object that is struck by the focused stream of electrons coming from the cathode. The target then stops the fast-moving electrons and thus creates the opportunity for the production of x-rays. (Nave, 2006, http://hyperphysics.phyastr.gsu.edu/Hbase/quantum/xtube.html) The Vacuum Another contributing factor called a vacuum, which allows for more efficient x-ray production and longer tube life. However, if there is just a little gas is inside the tube, the electron flow from the cathode to the anode is reduced, fewer x-rays are produced, and more heat is generated. If there is too much gas, x-ray production falls and the tube can fail. (Bushong, 2008, Ch.7 p.122). This is why the radiographer needs to be aware of the amount of heat that is produced during x-ray production because excessive heat can damage the tube: and without the tube x-ray production cannot be created. X-ray Interaction with Matter If x-ray production falls, then x-rays cannot interact with matter. X-ray production and x-ray interaction with matter help to form an image. X-rays interact with matter in five different characteristics: 1.) Coherent Scattering 2.) Compton Effect 3.) Photoelectric Effect 4.) Pair Production 5.) Photodistegration Only the Compton effect and the photoelectric effect are important in the process of creating an x-ray image. Coherent Scattering Coherent scattering is an interaction with low energy x-rays, below the diagnostic range. The incoming photon interacts with the atom causing it to become excited. Fauber (2009, Ch.3 p.49) has suggested that the x-ray doesnt lose energy, but changes direction. Coherent scattering contributes very little to the x-ray image, and only a few percent undergo this type of scatter. Coherent scatter contributes slightly to the deterioration of the image, often referred to as image noise, the general graying of an image that reduces image contrast. Most coherent scattered x-rays are emitted in a forward direction. Coherent scattering is a small importance to creating an x-ray image. However, if these scattered photons are absorbed within the tissue, they do contribute to the radiation exposure to the patient. Compton Effect The Compton effect can occur in all x-ray energies and are very important interaction with matter. When scattered x-rays interact with an outer-shell electron, the electron is thrown or ejected from the atom and the atom becomes ionized. The electron that was ejected is called a secondary electron. With the secondary electron ejected the x-ray scatter continues in a different direction with less energy then it started out with. During a Compton interaction the scattered x-ray and secondary electron have divided the energy between them, but usually the scattered x-ray maintains most of it. Eventually both lose all their energy and the scattered x-ray is absorbed photo electrically, while the secondary electron loses all of its energy through ionization and then falls into a vacancy in the electron shell created by a previous ionizing event. The purpose of the Compton effect is to reduce as much contrast on the x-ray image. Photoelectric Effect The photoelectric effect takes place when the incident x-ray is not scattered, but is totally absorbed during the ionization of an inner-shell electron. The incident photon disappears, and the k-shell electron; called a photoelectron is ejected from the atom. The x-ray image results from the difference between those x-rays that are absorbed by photoelectric interaction and those x-rays that are absorbed during ionization through the body as image-forming x-rays. Pair production Pair production is explained by Bushong (2008, Ch.10 pg.168) as an incident x-ray that has sufficient energy; it may escape interaction with electrons and come close enough to the nucleus of the atom to be influenced by the strong nuclear force field. This causes the x-ray to disappear between the nuclear field and x-ray, and in its place forms two electrons: a positron (positively charged) and one that is negatively charged. Pair production interacts with matter, but does not occur during x-ray imaging. Photodistegration The last characteristic of x-ray interaction with matter is Photodistegration, although it does not occur is diagnostic radiology. This process by which very high-energy x-rays (approximately reaching above 10 MeV) can escape interaction with electrons and the nuclear electric field, and can be absorbed directly by the nucleus. When this occurs the nucleus is raised to an excited state and instantly emits a nucleon or other nuclear fragments, which are released. (Bushong, 2008, Ch.10 pg169). Conclusion In conclusion x-ray production and x-ray interaction with matter help to create an x-ray image. Without both basic concepts a simple image would not be possible. Two of the three components that make up the inside of an x-ray tube is: the cathode and anode, which are both important factors in x-ray production. Similar to the five ways an x-ray can interact with matter, only two are important to the formation: the Compton effect and the photoelectric effect. X-ray production and x-ray are different in so many ways, also they go hand in hand, but without one the other does not exist and without either diagnostic imaging cannot occur.

The Importance of the Sea in The Awakening Essay -- Chopin Awakening

The Importance of the Sea in The Awakening      Ã‚   Throughout her novel, The Awakening, Kate Chopin uses symbolism and imagery to portray the main character's emergence into a state of spiritual awareness. The image that appears the most throughout the novel is that of the sea. â€Å"Chopin uses the sea to symbolize freedom, freedom from others and freedom to be one's self† (Martin 58). The protagonist, Edna Pontellier, wants that freedom, and with images of the sea, Chopin shows Edna's awakening desire to be free and her ultimate achievement of that freedom.    Edna's awakening begins with her vacation to the beach. There, she meets Robert Lebrun and develops an intense infatuation for him, an infatuation similar to those which she had in her youth and gave up when she married. The passionate feelings beginning to overwhelm her are both confusing and exciting. They lead to Edna beginning to ponder what her life is like and what she is like as a person. The spell of the sea influences these feelings which invite "the soul . . . to lose itself in mazes of inward contemplation" (Chopin 57). Edna begins to fall under the sea's spell and begins to evaluate her feelings about the life that she has.    During the summer of Edna's awakening, the sea's influence increases as she learns how to swim, an event which holds much more significance that her fellow vacationers realize. â€Å"To her friends, she has accomplished a simple feat; to Edna, she has accomplished a miracle† (Showalter 114). She has found a peace and tranquility in swimming which gives her the feeling of freedom. The narrator tells us that as she swims, "she seem[s] to be reaching out for the unlimited in which to lose herself" (Chopin 74). She sees the freedom t... ...ms out into the ocean for the final time, she finds her ultimate freedom.    In the end, the sea symbolizes freedom for Edna. It will never treat her as a possession like her husband has for so many years. It will not demand all of her time and attention as her children do. It will never abandon her as Robert does. It will enfold her "in its soft, close embrace" (Chopin 176) and allow her to experience the vast array of feelings that her life has forbidden her to do. The sea will allow her to be free.    Works Cited and Consulted Chopin, Kate. "The Awakening." 1899. The Complete Works of Kate Chopin. Ed. Per Seyersted.

Introduction To Aircraft Manufacturing Industry Engineering Essay

The planetary aircraft fabrication industry can be separated into two cardinal sections. Military and infinite application and civil or commercial aircraft. Commercial Aircraft comprises of little and big traveler aircrafts and even the lading aircrafts. The big aircraft fabrication is chiefly done by Boeing company of the United provinces of America and Airbus company of the European brotherhood. In the yesteryear, Boeing has been achieved success in taking over Martin Marietta and McDonnell Douglas, both had besides been in the industry of aircraft fabrication. Presently, the big aircraft fabrication industry is an oligopoly, dominated by Airbus and Boeing, which are in a ferocious competition against each other. There are other big makers besides, for illustration there is one in Russia but its consequences were irrelevant because its clients were limited to air hoses from Vietnam, Russia and other states of the former Soviet Union. The universe aircraft industry has gone under a really steady growing. Boeing estimates that the worldwide aircraft market would be deserving 5.4 trillion US dollars by 2024 to counterbalance a 5.2 % addition in world-wide air travel. It is estimated that 12,000 to 15,000 will be needed by 2020 to run into the turning demand. PESTLE AnalysisPoliticalLiberalization of travels between the European Union and the United States has resulted in demand of more aircrafts. The Aircraft Industry is a duopoly industry comprising of Airbus ( EU ) and Boeing ( US ) . If there are to be viewed from political consensus they are bipartisan political system. Anthony Downs proposed a authoritative theoretical account in the political scientific discipline that suits the state of affairs in the perfect manner. His proposal reversed the conservative connexion between party political orientations and elections. He said that alternatively of parties accomplishing triumph in the elections on the footing of the rightness of their docket, his findings give elections pre-eminence, with innuendo that all actions taken by the party are aimed at maximizing ballots. Harmonizing to Downes, both parties will seek to resemble each other every bit much as possible. Both parties will maintain their policies modestly different from each other. Besides bulk of electors merely want to see minor changes in authorities functionality. The Market of big and mid size aircrafts works on the same political orientation. There is an huge consensus among market participants to what an attractive merchandise comprises, that is, an economically efficient and safe aircraft. But there are besides some involvement cabals that have wagered in merchandise design, merely as there are much possible groups within a democratic system. A The Government of the United States and its Federal Aviation Administration ( FAA ) are considered to be influential as they look upon the largest air conveyance market in the universe. Regulations laid by the European and United states authorities will turn out to be a major drive force for orders of new aircraft in the coming old ages. In the similar manner, the deregulating of European air hoses, which begun in 1990 ‘s, promises to spread out the markets for smaller regional jets. Trade of big commercial jetliners has been tariff free under the understanding of General Agreement on Tariffs and Trade ( GATT ) . The high grade of political intercession has consequence on the purchase of aircraft. The determination of purchasers to purchase which aircraft depends on the political grounds because the support and intervention from the authorities could consequence the hereafter of purchasers. For Example, soon Boeing ‘s biggest market is China and is estimated to be for following twenty old ages. As a consequence China ‘s purchase of boeing aircrafts has led to batch of political influence in the United States.EconomicAir traffic in US and UK is likely to increase as they have merely recovered from the recession. The commercial aircraft is estimated to lift deserving US $ 2 trillion in the approaching 20 old ages, which will ensue into demand of 16,600 new aircrafts ( estimated ) . The largest demand is expected to come from air hoses from China, US and India. Huge sum of growing is expected from the Middle East states. It is expected that China entirely will necessitate 2,200 new a ircrafts to run into its travel demands. Besides, international cargo sector is estimated to turn by 253 % in the following 20 old ages. China being the biggest emerging market and sing its population size, the growing in air riders is likely to hit up which would ensue in increasing demand for new aircrafts. High Oil monetary values: looming oil monetary values have elevated the operating cost of air hoses. In the twelvemonth 2007, the world-wide air hose industry had to pay 136 billion US dollars for fuels, its a 300 % addition compared to what they had to pay in 2003. Even in 2008, when petroleum oil monetary values fell dramatically, it still accounted for 32 % of the operating disbursals. Global GDP- the primary factors in finding the demand of aircraft and growing in the industry is the GDP, which is expected to turn by 3.2 % by 2030 The planetary recession: The recession which impelled a theatrical bead in load factors in the center of 2008. In response, air hoses have been seting aircrafts out of service and rethinking programs to order replacing for the bing aircrafts. In the 3rd one-fourth of 2008 24 air hoses went bankrupt. The loses during this period were estimated about 4-8 billion US dollars. The recognition crunch: The recognition crunch in combination with the above mentioned factors, has made it difficult to buy new aircrafts, air hoses are happening troubles to finance new aircrafts. Despite of the recognition crunch, orders for concern and commercial jets have seen addition at the beginning of 2008, but the recognition crises has resulted in holds and recesss and failure to take bringing of many aircrafts.SocialRecent alterations in society have led to increase in air travel. Besides alterations in life manner of people and the point of view of air journey being a executable option. Demand of air travel is driven by convenience. However, the tendency is altering as the consumers travel determinations is chiefly based on monetary value. Rising cost and competition produced by low-priced bearers is impacting bulk of Airlines. Business travels, one time a stalls of income, now is a behavior by corporate travel guidelines. As a effect, air hoses are uniting their webs to use economic systems of graduated table, minimise environmental impact and offer smaller markets with new and improved services. The noise generated and CO2 emanation near the airdrome is besides a thing of higher concern as people populating near the airdrome are supercharging governments to alter thier operating manner.TechnologicalIn the commercial air power industry, there are immense sum of costs connected with Research and development for the development of a new aircraft. European Union authoritiess sustain European engineering R & A ; D sector, merely as the united provinces authorities does, though FAA, NASA, Department of Defence ( DOD ) and plans that reliefs export revenue enhancement. Though United provinces has three times more support than the European brotherhood. The Aircraft industry is really demanding with really high measure of clip and money dedicated to inventions and R & A ; D. Now a twenty-four hours ‘s C fibre is used for the building of an Aircraft organic structure. ( illustration: A350 XWB with 50 % C fiber organic structure ) Concentration on development on doing more fuel efficient engines for longer scopes. Use of alternate beginnings of fuel to antagonize raising oil monetary values The development of supersonic aircraft is besides a opportunity because it will take to creative activity of whole new market section. Commercial bearers will purchase these aircrafts to run into clients demand of making the finish rapidly and on clip. The largest and cost efficient promotion for commercial aircraft industry is the faster designing of planes. The augmented fabrication clip will salvage aircrafts makers clip on labour and assist them to break utilize resources. For Example: Boeing 777 used computing machine to plan a paradigm, this saved them the cost of constructing a existent paradigm. In today ‘s competitory universe, automatons are besides considered an effectual tool for the fabrication of aircraft.LegalThere are many limitations when it comes to come ining the market but due to globalization fortunes have changed and besides due to US unfastened skies understanding. Open skies understanding has led to smooth flow of national and international flights in and out of US, promoting Tourss and concern activities, bettering productiveness and creative activity of occupation chances and economic growing. United province ‘s unfastened skies policy has been proved really effectual in air hose globalisation. It enabled the air hose bearer ‘s limitless entree in the spouses market and right to travel to all center and beyond points. This understanding has offered the most operational flexibleness for air hose alliances. This understanding has been successful in accomplishing over 100 spouses from every portion of the universe and every degree of economic growing. Besides there is IATA ( International Air Transport Association ) . Its purpose is to supply aid to air hoses to diminish complexness of their procedure and increase rider convenience, diminishing costs and develop efficiency. The open uping simplifying the concern strategy is critical in this country. Furthermore, IATA ‘s primary precedence is safety and its purposes to continuously better safety criterions via IATA ‘s Operational safety audit ( IOSA ) .EnvironmentalEnvironment factors by and large include ecological facet of clime and conditions alteration, which in bend can act upon industries such as insurance, touristry and agriculture. Today, there is an consciousness of clime alteration in the heads of people, which is going a make up one's minding factor on how companies function and what are their offerings, because it can take to formation of a new market or devastation of the present market. ACARE is an European group of airdromes, eurocontrol, air hoses, makers, universities and members of EU and EU committee. Its primary challenges are – safety, sensible, quality, environment and security. Some of their aims are to cut down air accidents to 80 % , 15 minute less wait clip on airdromes for small distance finishs and 50 % less clip needed to market. One of most popular purpose of ACARE was to cut down specific CO2 discharge by 50 % , the discharge of NOx by 80 % , and to diminish the exterior noise of fixed wing aircraft by 10 dubniums per operation. For example- Boeing is a major component of the commercial air power industry. It is put to deathing some new programs to better its aircrafts environmental public presentation. Compared to show It besides claims that it will cut down its nursery gas emanations by 25 % by 2020. The intent of ACARE clearly reflects the demand of society, particularly in the country of security and stableness of environment. Besides, their purpose reflect the demands of aircraft operators, which are major driver for invention in engineering. The ACARE aims reflect demands which are demanded by society, peculiarly in the countries of environmental compatibility and security. On the other manus, the ACARE aims besides reflect the demands of aircraft operators, which are an of import driver for technological betterment. On the other manus, the mounting force per unit area from society sing emanations, noise around airdromes are impacting air hose operations. In add-on, with increasing force per unit area from society as a whole, every bit good as from local communities around airdromes, noise and local emanations have an impact on air hose operations.

Technology Changes of the Past and Present essays

Technology Changes of the Past and Present essays Technological Changes of the Past and Present The technology which surrounds almost everyone in the modern society, affects both work and leisure activities. Technology contains information that many would rather it did not have. It influences minds in good and bad ways, and it allows people to share information which they would otherwise not be able to attain. Even if a person does not own a computer or have credit cards, there is information on a computer somewhere about everyone. The technology which is just now beginning to be manipulated and harnessed is affecting the minds of small children and adolescents in ways that could be harmful. It is affecting our immediate future. It also gives another form of communication and exchange of information which was not available before, information that is both good and bad. Technology is one of the principal driving forces of the future; it is transforming our lives and shaping our future at rates unprecedented in history, with profound implications which we can't even begin to see or understand. Many different elements affect how satisfied we are with our lives. The impact of technology on these elements can change how safe, healthy and happy people feel. Throughout history, people have looked for better ways to meet their needs and to satisfy their expectations. Technology has improved the way people feed, clothe and shelter themselves. Technology has also changed other aspects of everyday life, such as health care, education, job satisfaction, and leisure time activities. People have used technology since they first chipped stone blades to improve their hunting. Yet some people call the current age the "Technological Age" because of society's dependence on technology. For the first time in human history, almost all the goods and services people use depend on technology. The products of technology are available to almost everyone in society. The economy of a country in...
