The Doppler Effect for Sound Waves

The Doppler Effect for Sound Waves The Doppler effect is a means by which wave properties (specifically, frequencies) are influenced by the movement of a source or listener. The picture to the right demonstrates how a moving source would distort the waves coming from it, due to the Doppler effect (also known as Doppler shift). If youve ever been waiting at a railroad crossing and listened to the train whistle, youve probably noticed that the pitch of the whistle changes as it moves relative to your position. Similarly, the pitch of a siren change as it approaches and then passes you on the road. Calculating the Doppler Effect Consider a situation where the motion is oriented in a line between the listener L and the source S, with the direction from the listener to the source as the positive direction. The velocities vL and vS are the velocities of the listener and source relative to the wave medium (air in this case, which is considered at rest). The speed of the sound wave, v, is always considered positive. Applying these motions, and skipping all the messy derivations, we get the frequency heard by the listener (fL) in terms of the frequency of the source (fS): fL [(v vL)/(v vS)] fS If the listener is at rest, then vL 0.If the source is at rest, then vS 0.This means that if neither the source nor the listener are moving, then fL fS, which is exactly what one would expect. If the listener is moving toward the source, then vL 0, though if its moving away from the source then vL 0. Alternately, if the source is moving toward the listener the motion is in the negative direction, so vS 0, but if the source is moving away from the listener then vS 0. Doppler Effect and Other Waves The Doppler effect is fundamentally a property of the behavior of physical waves, so there is no reason to believe that it applies only to sound waves. Indeed, any sort of wave would seem to exhibit the Doppler effect. This same concept can be applied not only to light waves. This shifts the light along the electromagnetic spectrum of light (both visible light and beyond), creating a Doppler shift in light waves that is called either a redshift or blueshift, depending on whether the source and observer are moving away from each other or toward each other. In 1927, the astronomer Edwin Hubble observed the light from distant galaxies shifted in a manner that matched the predictions of the Doppler shift and was able to use that to predict the speed with which they were moving away from the Earth. It turned out that, in general, distant galaxies were moving away from the Earth more quickly than nearby galaxies. This discovery helped convince astronomers and physicists (including ​Albert Einstein) that the universe was actually expanding, instead of remaining static for all eternity, and ultimately these observations led to the development of the big bang theory.

How to Display Menu Item Hints in Delphi Applications

How to Display Menu Item Hints in Delphi Applications Use specific coding language to program Delphi applications to display a hint, or tooltip, when the mouse hovers over a menu component. If the ShowHint property is set to true and you add text to the hint property, this message will be displayed when the mouse is placed over the component (a TButton, for example). Enable Hints for Menu Items Because of the way Windows is designed, even if you set the value for the hint property to a menu item, the popup hint will not get displayed. However, the Windows start menu items do display hints. The favorites menu in Internet Explorer also displays menu item hints. It is possible to use the OnHint event of the global application variable in Delphi applications to display menu item hints in a status bar. Windows does not expose the messages needed to support a traditional OnMouseEnter event. However, the WM_MENUSELECT message is sent when the user selects a menu item. The WM_MENUSELECT implementation of the TCustomForm (ancestor of the TForm) sets the menu item hint to Application.Hint so it can be used in the Application.OnHint event. If you want to add menu item popup hints (tooltips) to your Delphi application menus, focus on the WM_MenuSelect message. Popup Hints Since you cannot rely on the Application.ActivateHint method to display the hint window for menu items (as menu handling is completely done by Windows), to get the hint window displayed you must create your own version of the hint window by deriving a new class from the THintWindow. Heres how to create a TMenuItemHint class. This is a hint widow that actually gets displayed for menu items! First, you need to handle the WM_MENUSELECT Windows message: type TForm1 class(TForm) ... private procedure WMMenuSelect(var Msg: TWMMenuSelect) ; message WM_MENUSELECT; end...implementation...procedure TForm1.WMMenuSelect(var Msg: TWMMenuSelect) ;var  Ã‚  menuItem : TMenuItem;  Ã‚  hSubMenu : HMENU;begin inherited; // from TCustomForm (so that Application.Hint is assigned) menuItem : nil; if (Msg.MenuFlag $FFFF) or (Msg.IDItem 0) then begin if Msg.MenuFlag and MF_POPUP MF_POPUP then begin hSubMenu : GetSubMenu(Msg.Menu, Msg.IDItem) ; menuItem : Self.Menu.FindItem(hSubMenu, fkHandle) ; end else begin menuItem : Self.Menu.FindItem(Msg.IDItem, fkCommand) ; end; end;  Ã‚  miHint.DoActivateHint(menuItem) ;end; (*WMMenuSelect*) Quick info: the WM_MENUSELECT message is sent to a menus owner window when the user selects (but does not click) a menu item. Using the FindItem method of the TMenu class, you can get the menu item currently selected. Parameters of the FindItem function relate to the properties of the message received. Once we know what menu item the mouse is over, we call the DoActivateHint method of the TMenuItemHint class. The miHint variable is defined as var miHint : TMenuItemHint and is created in the Forms OnCreate event handler. Now, whats left is the implementation of the TMenuItemHint class. Heres the interface part: TMenuItemHint class(THintWindow)private activeMenuItem : TMenuItem; showTimer : TTimer; hideTimer : TTimer; procedure HideTime(Sender : TObject) ; procedure ShowTime(Sender : TObject) ;public constructor Create(AOwner : TComponent) ; override; procedure DoActivateHint(menuItem : TMenuItem) ; destructor Destroy; override;end; Basically, the DoActivateHint function calls the ActivateHint method of the THintWindow using the TMenuItems Hint property (if it is assigned). The showTimer is used to ensure that the HintPause of the Application elapses before the hint is displayed. The hideTimer uses Application.HintHidePause to hide the hint window after a specified interval. Using Menu Item Hints While some might say that it is not a good design to display hints for menu items, there are situations where actually displaying menu item hints is much better than using a status bar. A most recently used (MRU) menu item list is one such case. A custom taskbar menu is another.

How Can Critical Thinking Help Managers to Do their Jobs More Assignment

How Can Critical Thinking Help Managers to Do their Jobs More Effectively - Assignment Example In order to be contented with continuous re-learning, the power of critical thinking of self-critique is vital (Paul, Beach, 1995). Critical thinking may be defined as thinking that involves the relevance of judgment. It is developed and polished as an easy rational structure to educate people on a purpose-driven appraisal process. It’s all concerning the methodical use of one’s own decision. The tendency is to consider critical thinking as a cold, scientific or objective way of visualizing things, however, this is wrong. The truth is that everyone is attentive in his own subjective experience of the world. The rigid truth that is carried with one into each new state of affairs and it would be unwise to act as if that one can merely put that away at will so as to view the present matter without partiality or judgment. Actually, it’s not even desirable. The requirement is that for people to build the optimal use of their knowledge and to act insensibly suitable ways in order to accomplish their objectives (Wells, N.D). Everybody thinks; it is the natural to do so. However, most of the thinking is biased, unclear, partial, and unaware. Thus the quality of lives and that of the produce depends exactly on the quality of the thought. Brilliance in thought must be methodically educated (Paul, Elder, 2001).   Faculties concur generally that the growth of students higher-order intellectual or cognitive aptitude is the vital educational task of institutions. These abilities strengthen students insight of the world and the ensuing decisions they make. Particularly, critical thinking - the ability to assess expertly and fairly the quality of proof and spot mistake, pretense, exploitation, and prejudice - is vital to both personal victory and state desires (Gardiner,  1995).

The Fund for Electronic goods recycling project Essay

The Fund for Electronic goods recycling project - Essay Example Discussion Available funding bodies Small business owners need to rely on investors for financing their activities. For any start-up of a business or introducing a new product, upgrading of equipment, investors are required to help provide the company with funds. There are several types of investors for a business. They are as follows. Angle Investors Angle investors are basically affluent individuals who provide funds for a business start-up. He usually does it in exchange for ownership equity or convertible debt. An Angel investor follows his basic instincts and accordingly invests in businesses which may otherwise face difficulties in attracting other investors to fund their operation. In some cases they want to get a share of their investment in case of profit by the business. He will want a certain predetermined percentage of his investment or in other cases in may want partial ownership of the business in which he has invested, or in other cases management decisions. Angel inve stors invest typically from hundreds or thousands to a few million dollars. Advantages of angel investors Most angel investors can provide business with the ability to generate small amounts of money needed. It can be less than $5, 00,000 or even upto $ 1 million. Since most early ventures require small amount so money, Angel investors can provide them with this amount from their own personal source of funds. When entrepreneurs have exhausted their supply of money from family, friend, bank loans, personal savings and credit cards for their start-up business they can seek the help of angel investors to help fill the equity gap needed to do the business. Angel investors are more flexible in their business arrangement as compared to traditional source of money lenders like venture capitalist and banks. Since they invest their own money it is possible to negotiate their business deals. They also don’t require highly monthly fees as required by banks and credit cards. Angel invest ors typically invest according to their own risk. Hence it is considered as high risk business investments. Since there is no record of company success for the new start-up, the angle investors is perfect for start-up. Also nowadays Angel investors are typically located everywhere across all the industries. Disadvantages of angel investors Angel investors typically do not make follow on investments, because of the risk associated with reinvesting is even more for an unsuccessful company. Angel investors can sometimes be deceptive. Though majority of the angel investors can look beyond the return of their investments, there are few angel investors who are greedy and want more money in return rather than promoting good for the company. Also they tend to be less patient with new entrepreneurs and hence don’t provide them with proper guidance or mentoring in their early stage of the business. Sometimes the return on investment which they want can be costly. Peer-To-Peer Lending P eer-to-Peer lending which is also known as social lending, person-to-person lending is the process of lending money to its peers also known as unrelated individuals, without going through banks or other financial intermediary (Mu and Gnyawali, 2003, pp. 689-711). These types of lending typically takes place online on company’

The History of Blaan Essay Example for Free

The History of Blaan Essay The origin of the Blaan is obscured by the mist of antiquity. Though a people of rich traditional, almost nothing is known about them in view of the absence of ancient records. The Blaans belong to the second group of people who migrated to the Islands between 12,000 and 15,000 years ago. According to the Blaan folk tale told by Fulong, the early Blaans arrived the country next to the To Bali or tiny people. Historians have identified these tiny people as pygmies or negritos (little black) who said to have arrived in the Philippines about 25,000 years ago across the land bridge that was connected the archipelago with mainland Asia. It appears that the Blaans were very much ahead of the Indonesians by almost 10,000 years and cannot logically belongs to the Indonesian type A. The term Blaan, refers to a socio-linguistic group, on the Island of Mindanao, with covers coastal, lowland and highland groups from approximately as far North of Mt. Buluan, to as far South as the Sarangani Peninsula. Both the coastal, lowland and highland distinctions are based in geographical and ecological considerations as will as historical contact with other groups. The coastal and lowland Blaan groups tend to display a much more heterogeneous composition that the more homogeneous highland groups. As such the coastal and lowland groups in the highland are which display a strong sense of culture identity, as will as, more traditional Blaan practice. [pic] HISTORY OF BLAAN ASSOCIATED TO THE LAND. The people come from the land, without the land, there would be no people. The land, comes from the people for without the people, there would be no cultivated land. This is because land to the tribal is as a partner in life-not as commodity, not as a property that is owned and which may be bartered or sold. For centuries, the tribal people have been able to do just this quite successfully, maintaining ecological balance within their territory maintaining harmony with their environment. The traditional kaingin system of farming practiced by the majority of tribal Filipino has kept the soil fertile and has given flora and fauna, time regenerate land, life and power. The Fulo Bato Blaan consider themselves as one of the highland Blaan groups. According to highland Blaan traditional relief and custom, the spiritual entities, who inhabit the earth and the sky, are the true owners of the land for Blaan. [pic] Blaan says, that, the Blaan are like the banana, before a generation dies, new roots appear and grow. They grow up and always grow into bananas. They never grow into papaya. In the same way, each new generation of Blaan grow up with the same responsibilities, the previous generation, the same they never change. Blaan relationship are characterized by the interdependence, while each village has property rights over territorial lands, individuals can take as much land as needed provided that this is not in use at the time when a field is abandoned, the ownership revert to the community or (Banwu) personal property applies to products of own labor and still, house, furnishing, weapons, tools, and land crops. [pic] Many Blaan are very upset about the loss of the traditional lands to non-Blaan groups. Some Blaans believe that the purchase of land is only practical method of obtaining their land from the non- Blaan group, who currently occupy it. BLAAN LANGUAGE: Ani sen aye tana go. La ti fan don ko agtagak go di gamo. Ani sen aye go sol. Benwu fan go tayok di gamo. ENGLISH LANGUAGE: This is my traditional land. I dont want to leave this land. This is my homeland that I will leave to go. The Blaan people have been struggling for the recognition of their Ancestral Domain. The issue goes beyond simply a question of land use. The manner by which the Blaan people relate to their land resources deeply inter-wines with the customs, culture and political practices. Thus, it is an issue of a people life in its totality, and their struggle is an expression of their self-determination to carve their own destiny as a distinct people. [pic] The Blaan people have the right to maintain the distinctive spiritual relationship with their land, water and resources. They have the right to own and develop these. Their environment and their culture and intellectual property must be protected. The Blaan people have the right to control the development of their land. Government shall assist the Blaan people to preserve and protect their sacred sites. The Blaan people have the right to their own language and government hall ensure that the Blaan people can understand and he understand through interpretations and other appropriate ways in legal and other proceedings. The Blaan people value their culture and their tradition. They want to nurture it and maintain it. They want others to respect their right to do so. Blaan ancestral domain (tabi tana) and culture identity must be respected. BONG BANWU.is a big community. It is not only a community of people, but also includes their alnigo or clearing, gumlok or the hunting ground, bolol or the mountains, e-el or the rivers, ritual sites and other geographic and human features, such as burial grounds. This domain is defined by territorial boundaries. In the past, the term Bong Banwu was used by the highland Blaan to refer to a very large village and its accompanying and/ or surrounding land. One village was conceptualized by the Blaan as the residence of one mans family. The name of the familys most senior male was often used to refer to the village and its surrounding area. The locality in which the residence of the Bong Fulong is located is usually indicated by a higher population density.

Ib Eggshell Report

Candidate's name: Eunika Orlowska Candidate's number: School's name: School's number: Determining the amount of CaCO3 in eggshell of hen's egg | Design | DCP | CE | Aspect 1 | | | | Aspect 2 | | | | Aspect 3 | | | | Introduction: The back titration is a method used in determining the amount of excess of the reagent. The calcium carbonate is a substance which gives the eggshell stiffness. Research question: What is the amount of calcium carbonate in the eggshell measured by back titration? Table 1. Variables.Type of variable | Variable | Unit | Dependent | Amount of calcium carbonate in eggshell | % by mass | Independent | Volume of titrated excess of hydrochloric aced | cm3 | Controlled | Volume of hydrochloric acid Weight of eggshell Temperature Amount of phenolophateine | cm3 g oC drop | Uncontrolled | Purity of solutions Biological diversity of eggs Pressure | – – hPa | Equipment: buret 5 beakers 50 cm3 baguette 1 plastic pipette balance clamp 2,5 g of eggshell morta r 100 cm3 of 1moldm-3 hydrochloric acid ap. 70 cm3 of 1moldm-3 sodium hydroxide 20 cm3 pipette Risk assessment: you have to remember to wear gloves, goggles and apron. Solutions may be irritating. Method: Crush to dust eggshell in the mortar. Fill each of the 5 beakers with 20 cm3 of hydrochloric acid measured by glass pipette. Add 0. 5 g of eggshell dust to each beaker, measured by balance. While the reaction of eggshell with acid occurs, prepare the buret and clamp for titration. Make sure they are clean. Pour NaOH solution into the buret to the ‘0' level. Make sure all of the eggshell reacted with the HCl. If not, you can help the reaction by using the baguette.Put two drops of phenolophateine into each beaker using the plastic pipette. Take the first beaker and titrate the excess of hydrochloric acid. When the solution starts to be pinkish, record the volume of titrated NaOH. Refill the buret to the ‘0' level and repeat the procedure for each beaker. Remember to reco rd the results. Remember to be careful and to leave your workplace clean! Data Collection Table 2. Raw data. The weight of eggshell reacting with HCl and titrated NaOH. Number of trial | Weight of eggshell [g ±0,01g] | Volume of HCl [cm3 ±0,05cm3] | Volume of titrated NaOH [cm3 ±0,05cm3] | 1 | 0. 9 | 20. 00 | 9. 60 | 2 | 0. 50 | 20. 00 | 11. 50 | 3 | 0. 51 | 20. 00 | 11. 60 | 4 | 0. 50 | 20. 00 | 9. 90 | 5 | 0. 50 | 20. 00 | 10. 30 | Mean | 0. 50 ±0,01 | 20. 00 ±0,05 | 9. 93 ±0,05 | Standard deviation | 0. 00047 | 0. 00 | 0. 29 | Uncertanties were taken as in measurments, not calculated by formula, to avoid too large and unreliable uncertainties in further calculations in which they're calculated according to formulas: in case of division and multiplication: =dA/A+dB/B, where d is overall uncertainty, dA is uncertainty of A and dB is uncertainty of B in case of addition and subtraction: d=dA+dB, where where d is overall uncertainty, dA is uncertainty of A and dB is uncer tainty of B Trials 2 and 3 were rejected because of too large differentiation of results. Data Processing Two reactions occured in the experiment. Firstly, the HCl reacted with CaCO3 and secondly, the excess of HCl was neutralized by NaOH. 2HCl + CaCO3 > CaCl2 + CO2 + H2O HCl + NaOH > NaCl + H2O 1. Calculating the amount of HCl at the beginning of reaction CmHCl = 1. 0 moldm-3 VHCl = 20. 00 cm3 = 0. 20 dm3  ± 0. 00005 n = Cm * V n = 1. 0* 0. 020 = 0. 020 mol  ± 0. 00025 2. Calculating mean amount of NaOH which neutralized the excess of HCl CmNaOH = 1. 0 moldm-3 VNaOH = 9. 93 cm3 = 0. 0099 dm3  ± 0. 00005 n = Cm * V n = 1. 0 * 0. 0099 = 0. 0099 mol  ± 0. 0005 3. Calculating the amount of HCl which reacted with CaCO3 0. 020 mol – 0. 0099dm3 = 0. 010 mol  ± 0. 00075 4. Calculating the amount of CaCO3 which was in the eggshell We know that the molar ratio in the reaction between HCl and CaCO3 is 2/1, which means that 2 moles of HCl react with 1 mole of CaCO3. If 0. 010 moles of HCl reacted with CaCO3 then there was 0. 05 mole of CaCO3 in the eggshell. nCaCO3 = 0. 010/2 = 0. 005 ±0. 0075 5. Calculating the percentage of CaCO3 in the eggshell. MCaCO3 = 40. 09 + 12. 01 + 3 * 16,00 = 100. 1 gmol-1 nCaCO3 = 0. 005 mol  ± 0. 0075 m = M * n m = 0. 005*100. 1 = 0. 50 g  ± 0. 0075 meggshell=0. 50  ± 0. 01 CCaCO3 in eggshell = 0. 50 / 0. 50 = 100 %  ± 3. 5% Table 3. The results and uncertaities Calculated value | Value | Uncertainty | Number of moles of HCl at the beginning of reaction | 0. 020 mol | 0. 00025 mol | Mean amount of NaOH which neutralized HCl | 0. 0099 mol | 0. 005 mol | Mean amount of HCl which reacted with CaCO3 in the eggshell | 0. 010 mol | 0. 00075 mol | Number of moles of CaCO3 in the eggshell | 0. 005 mol | 0. 0075 mol | Molar mass of CaCO3 | 100,1 gmol-1 | – | Percentage of CaCO3 | 100% | 3. 5% | The eggshell consists of 94-97% of calcium carbonate, meanly 95. 5 %. From collected data it is 100%, which suggests that pe rcentage error was not big and remains in accepted value of 20%. percentage error = (|theoretical value – experimental value| ? theoretical value) x 100% = (95. 5 – 100 ? 95. 5) = 4 %Conclusion and Evaluation The eggshell consists of 94 – 97% of calcium carbonate. The experiment suggests that the eggshell has 100% of calcium carbonate and the percentage error is 4 % which means calculations and results where accurate. The fact that the result has shown 100% of calcium carbonate in the eggshell may lay in the construction of eggshell which is biological â€Å"machine† to give hen's embryo the best possible environment for development. Apart from calcium carbonate, there are other components of eggshell, for example magnesium carbonate and calcium phosphate which also react with hydrochloric acid.Reaction of calcium phosphate with hydrochloric acid: Ca3(PO4)2 + 6HCl > 3CaCl2 + 2H3PO4 this reaction should't have influence on titration that much, because as a result there's the same number of hydrogen ions which can be neutralized, but the second reaction, of magnesium carbonate and hydrochloric acid: MgCO3 + 2HCl > MgCl2 + CO2 + H2O also takes HCl to it's reaction, decreases number of H+ ions and so suggests that more HCl reacted with calcium carbonate. This is the uncontrolled variable, the impurity of the eggshell, which affected the result.Other factor, which may have had influence on the results is the human's imprecision. The used equipment was as accurate as possible in school laboratory, but still, the titration is made by hand and by eye, which may make mistakes although back titration is the best possible way in school laboratory to check the amount of particular components in mixtures. Other method, which would distinguish between magnesium carbonate and calcium carbonate is gas spectrometry – mass spectrometry. This method uses combined gas chromatography and mass spectrometry. First, the substance is put into gas chr omatograph.The mobile phase, in which the particles of substances move towards the stationary phase is made of unreactive gas, such as nitrogen or helium. In this, the substance is separated into particular components and then, the mass spectrometer analyses the components to identify them. This method is commonly used to determine the ingredients of substances, of food, beverages, perfumes. Also, it is useful in medicine and and in exploring Universe, for example, one GC-MS was taken by Curiosity to examine the surface of Mars. Summing up: in school laboratory, accuracy of experiments is limited by equipment.Better accuracy can be obtained by using more accurate balance, as no other equipment can be changed in used method. Back titration can't be replaced by other methods of determining the percentage of CaCO3 in the eggshell, as it is the best way to do it in school laboratory, although generally more accurate methods are created, using machines which exclude the human factor from experiments, for example gas chromatography – mass spectrometry.

Problems Encountered by the Students Introduction Essay

The continuous learning of students through the help of books, teachers, and even Internet is a fact which shows that knowledge still flourishes in our humanity. Life as a student is said to be fun yet also stressful. Requirements, reports, and especially examinations abound student’s life especially during the high school life. In many cases, students of today’s society are often provided with poor study skills, preventing them of all chance for a satisfying grade. Studying is a major concept of education, and if the problem continues more and more students will be rejected from opportunities they wished they’d had. Opportunities that include future education at college, a chance to gain important knowledge, or even an opportunity to receive a high-paying job. Traditionally, teachers are encouraged to believe that the learning environment must be orderly and quiet. However, more teachers are using activities occurring at the same time can make for noisy classrooms. But it would a mistake to conclude that in such classrooms student are not learning. Student that practice disruptive behavior cause disciplinary problems in the classrooms student and have negative efforts on student it may also lead to low achievement. The importance of the study emerged from the fact that the above literature indicated that classroom problems face the teachers, and try to investigate those problems in order to come up with solutions. In student’s mental abilities, teachers face in the classroom a group of students who suffer from the slow down, faltering and failure in learning and they need more time than their colleagues need to accomplish any learning task. Such students are characterized by a number of characteristics, including problems of language, oral expression, and unable to pay attention, memory problems, and the dispersal of attention. The family lifestyle and environment will put its mark on controlling the behaviors of students. Some student’s behavior can be unacceptable at school. Also, the level of behavior that is acceptable and allowed in the  family, the way the family acts with one another, leads the student to unacceptable performance in the school. Parents indirectly share in creating problems when they insist on their kid’s grades, and achievements to be always high. This lead to feeling of anger, and worry, and create student behavioral problems inside the classroom.

Advantages of Using Trans-Saharan and Indian Ocean Trade essays

Advantages of Using Trans-Saharan and Indian Ocean Trade essays Traveling merchants were a major vehicle for creating vast interregional networks and trade routes in the great overland oceanic networks increased in importance (Interregional Pp). Transportation was an important factor, whether meaning better ships and navigation, or the increasingly widespread use of the camel as a ship of the desert (Tropical Pp). Before the 1st millennium CE, the Sahara was an almost impassable barrier separating the North African coast from sub-Saharan Africa (Tropical Pp). And the Atlantic Ocean not a highway for travel, but a barrier (Tropical Pp). The only route connecting the two areas was the Nile, however, in its southern reaches travel was made difficult by both rapids and surrounding jungle (Tropical Pp). The monsoon winds were the propulsion for ships, the driving force for navigation in the Indian Ocean, blowing ships northeast in summer, and then back southwest in winter (Tropical Pp). Indian Ocean trade first increased under local groups from southern Arabia, India, and Southeast Asia, then outside groups, such as the Chinese became involved and a network establishing a link between East African commercial city-states and the Middle East, India, and Southeast Asia (Interregional Pp). By the 16th century, the Portuguese dominated this system and linked it directly, rather than through Mediterranean intermediaries, with Europe (Interregional Pp). Although products, such as spices from Southeast Asia and other expensive goods, continued to be exchanged, bulk good such as sugar and textiles were increasingly involved (Interregional Pp).

Argumentative Essay : Bullying Among Teenagers -- Adolescence, Puberty,

In recent times, there is no doubt that there has been an upsurge of disrespectful manners among teenagers. Today, teenagers are completely unpredictable with what they can and cannot do in regards to their behaviors. Many people do not want to deal or try to figure out what is going on in the minds of teenagers as they feel it is just easier to view all incidences of this way of life with a blind eye. This occurrence has escalated to the point that everywhere you go, it is likely to find yourself amongst one or two rude teenagers. They treat people with no respect and the shocking part of it is that they show no remorse for their actions. Primeval cultures upheld respect as one of the important traits kids should have when dealing with adults. Although cultures have many contrariety, but at the same time, had elements that united them through time and geographic region. Many of these elements were included in religious, social and moral laws. In religions and western philosophy the element of respect is held with topmost importance allowing a clear boundary between those who are young and naive and those who are experienced and mature. The view that kids has to show respect when dealing with people that are significantly older than them has gradually diminished over the years. Emergence of new cultures has affected the rate of discipline we give to young ones. High school students are popularly known for their notorious disrespect for authority and adults in general. Many continually wonder how children change from been respectful at a very young age to been disrespectful at their teenage years. This led to various research and studies into teenagers and their disrespectful attitudes. Studies and researchfilled with optimism, hopefulness and encouragement, not disrespect towards other people in the society.According to the Bible in the book of proverbs 22:6 (New International Version) states that â€Å"train up a child in the way he should go and when he is old he would not depart from it.† parental and societal failure to inculcate good manners into children has led to the various societal severities. If your child is showing signs of disrespect to you, their teachers or other family members it is important that you do not wait until it gets out of hand before seeking help from a therapist who can make recommendations depending on the situation. Teamwork of all social institutions is the only way the problem of bad manners can be stopped. When the family, the media and schools come together with determination to tackle this issue, then America will be a better place.
