Analysis Of A Letter I My Son By James Baldwin

Racism in North America, although a social construct, is almost a natural instinct. Humans are not born with race but rather are raised to see people a certain way which is a quality that stays with them throughout the rest of their lives. â€Å"Race discrimination involves treating someone unfavorably because of the individuals certain race or because of personal characteristics associated with race such as hair texture, skin color, or certain facial features† (Equal Employment Opportunity Commission, para. 1). Any country located on the Asian continent like China and India are naturally considered â€Å"Asian†. The fact being Middle Eastern countries Saudi Arabia and Iraq are also Asian. In ‘A letter to my nephew’, James Baldwin emphasises how poorly the black culture is being treated. Stressing how, specifically, his people are treated so poorly only based on their skin color which takes away from one s culture and tradition involving the takeover of rac ism, minimizing the culture. What most fail to realize is that Asians, are racially assaulted by numerous individuals and this goes unpunished in the U.S and must be acknowledged. History of racism against Asians is rarely discussed. The Angell Treaty of 1880 modified the US-China Burlingame Treaty of 1868, accepting the suspension of Chinese immigrants in the U.S. Followed by â€Å"The Chinese Exclusion Act which was a United States federal law signed by President Chester A.

Criminal Justice Process Essay example - 1094 Words

When a crime is committed against another person, then justice must be served to those who committed the crime. In some cases the crimes involve sexual attacks on grown adults while some offenses are against minors. In these examples the underling connection is the committed crimes of sexual abuse or sexual assault on adults and minors. When these crimes are brought before the justice system they are processed and the convicted are given a sentence to carry out but sometimes those sentences may not provide efficient time to produce the required outcome of correcting the individual or may be determined that there is no fixing the convicted disorder. The United States Supreme Court decision to hold a mentally ill, sexually dangerous†¦show more content†¦These two statics prove that those convict of sexually assault have a high probability for committing the same acts upon new victims and if an inmate does not show that any sort of treatment has worked then they will victim ize more innocent people. Since sexual offenders are often categorized has having an illness or underlining problem than the treatment must have time to take effect. The treatment for sexual offenders is done in a three principal approach which is cognitive behavioral approach, psycho-educational approach, and pharmacological approach. The cognitive behavioral approach gives emphasis on altering the habits of the offended relating toward sexual offending and â€Å"deviant patterns of arousal†. (CSOM) This means altering the daily habits of the offender which may be everything they had known previously to incarceration. The second principal of psycho-educational focuses on altering the offender’s state of mind toward their victims and attempts to instill the understanding of how they inflicted harm with their actions. With psychology there is never a set time on how long a set goal will be reached. Times vary between individuals and can sometime never reach their desired outcome. In conjunction with those previous principals the offenders are also treated under the pharmacologicalShow MoreRelatedInvestigation Of The Criminal Justice Process947 Words   |  4 PagesThe criminal justice process begins with a report of violation of the law by a citizen or witnessed by a police officer first hand.

Transfer Functions with MATLAB 6. Time Response Analysis with MATLAB 1. Introduction An important step in the analysis and design of control systems is the mathematical modelling of the controlled process. There are a number of mathematical representations to describe a controlled process: Differential equations: You have learned this before. Transfer function: It is defined as the ratio of the Laplace transform of the output variable to the Laplace transform of the input variable, with all zero initial conditions. Block diagram: It is used to represent all types of systems. It can be used, together with transfer functions, to describe the cause and effect relationships throughout the system. State-space-representation: You will study this in an advanced Control Systems Design course. 1. 1. Linear Time-Variant and Linear Time-Invariant Systems Definition 1: A time-variable differential equation is a differential equation with one or more of its coefficients are functions of time, t. For example, the differential equation: d 2 y( t ) t2 + y( t ) = u ( t ) dt 2 (where u and y are dependent variables) is time-variable since the term t2d2y/dt2 depends explicitly on t through the coefficient t2. An example of a time-varying system is a spacecraft system which the mass of spacecraft changes during flight due to fuel consumption. Definition 2: A time-invariant differential equation is a differential equation in which none of its coefficients depend on the independent time variable, t. For example, the differential equation: d 2 y( t ) dy( t ) m +b + y( t ) = u ( t ) 2 dt dt where the coefficients m and b are constants, is time-invariant since the equation depends only implicitly on t through the dependent variables y and u and their derivatives. 1 ECM2105 – Control Engineering Dr Mustafa M Aziz (2010) ________________________________________________________________________________ Dynamic systems that are described by linear, constant-coefficient, differential equations are called linear time-invariant (LTI) systems. 2. Transfer Function of Linear Time-Invariant (LTI) Systems The transfer function of a linear, time-invariant system is defined as the ratio of the Laplace (driving function) U(s) = transform of the output (response function), Y(s) = {y(t)}, to the Laplace transform of the input {u(t)}, under the assumption that all initial conditions are zero. u(t) System differential equation y(t) Taking the Laplace transform with zero initial conditions, U(s) Transfer function: System transfer function G (s) = Y(s) Y(s) U(s) A dynamic system can be described by the following time-invariant differential equation: an d n y( t ) d n ? 1 y( t ) dy( t ) + a n ? 1 + L + a1 + a 0 y( t ) n ? 1 dt dt dt d m u(t) d m ? 1 u ( t ) du ( t ) = bm + b m ? 1 + L + b1 + b 0 u(t) m m ? 1 dt dt dt Taking the Laplace transform and considering zero initial conditions we have: (a n ) ( ) s n + a n ? 1s n ? 1 + L + a 1s + a 0 Y(s) = b m s m + b m ? 1s m ? 1 + L + b1s + b 0 U(s) The transfer function between u(t) and y(t) is given by: Y(s) b m s m + b m ? 1s m ? 1 + L + b1s + b 0 M (s) = = G (s) = U(s) N(s) a n s n + a n ? 1s n ? 1 + L + a 1s + a 0 where G(s) = M(s)/N(s) is the transfer function of the system; the roots of N(s) are called poles of the system and the roots of M(s) are called zeros of the system. By setting the denominator function to zero, we obtain what is referred to as the characteristic equation: ansn + an-1sn-1 + + a1s + a0 = 0 We shall see later that the stability of linear, SISO systems is completely governed by the roots of the characteristic equation. 2 ECM2105 – Control Engineering Dr Mustafa M Aziz (2010) ________________________________________________________________________________ A transfer function has the following properties: †¢ The transfer function is defined only for a linear time-invariant system. It is not defined for nonlinear systems. The transfer function between a pair of input and output variables is the ratio of the Laplace transform of the output to the Laplace transform of the input. †¢ All initial conditions of the system are set to zero. †¢ The transfer function is independent of the input of the system. To derive the transfer function of a system, we use the following procedures: 1. Develop the differential equation f or the system by using the physical laws, e. g. Newton’s laws and Kirchhoff’s laws. 2. Take the Laplace transform of the differential equation under the zero initial conditions. 3. Take the ratio of the output Y(s) to the input U(s). This ratio is the transfer function.

Set all inputs except one equal to zero Determine the output signal due to this one non-zero input Repeat the above steps for each of the remaining inputs in turn The total output of the system is the algebraic sum (superposition) of the outputs due to each of the inputs.

Transfer Functions with MATLAB A transfer function of a linear time-invariant (LTI) system can be entered into MATLAB using the command tf(num,den) where num and den are row vectors containing, respectively, the coefficients of the numerator and denominator polynomials of the transfer function. For example, the transfer function: G (s) = 3s + 1 s + 3s + 2 2 can be entered into MATLAB by typing the following on the command line: num = [3 1]; den = [1 3 2]; G = tf(num,den) The output on the MATLAB command window would be: Transfer function: 3s+1 ————s^2 + 3 s + 2 Once the various transfer functions have been entered, you can combine them together using arithmetic operations such as addition and multiplication to evaluate the transfer function of a cascaded system. The following table lists the most common systems connections and the corresponding MATLAB commands to implement them. In the following, SYS refers to the transfer function of a system, i. e. SYS = Y(s)/R(s). System MATLAB command Series connection: R(s) Y(s) G1 G2 SYS = G1*G2 or SYS = series(G1,G2) Parallel connection: G1 + R(s) SYS = G1  ± G2 or SYS = parallel(G1, ±G2) Y(s)  ± G2 Negative feedback connection: R(s) Y(s) +_ G(s) SYS = feedback(G,H) H(s) 13 ECM2105 – Control Engineering Dr Mustafa M Aziz (2010) ________________________________________________________________________________ R(s) Y(s) +_ G1 G2 H Example: Evaluate the transfer function of the feedback system shown in the figure above using MATLAB where G1(s) = 4, G2(s) = 1/(s+2) and H(s) = 5s. Solution: Type the following in the MATLAB command line: G1 = tf([0 4],[0 1]); G2 = tf([0 1],[1 2]); H = tf([5 0],[0 1]); SYS = feedback(G1*G2,H) This produces the following output on the command window (check this result): Transfer function: 4 ——-21 s + 2 Exercise: Compute the closed-loop transfer function of the following system using MATLAB. R(s) +_ 1 s +1 14 s+2 s+3 Y(s) ECM2105 – Control Engineering Dr Mustafa M Aziz (2010) ________________________________________________________________________________ 6. Time Response Analysis with MATLAB After entering the transfer function of a LTI system, we can compute and plot the time response of this system due to different input stimuli in MATLAB. In particular, we will consider the step response, the impulse response, the ramp response, and responses to other simple inputs. 6. 1. Step response To plot the unit-step response of the LTI system SYS=tf(num,den) in MATLAB, we use the command step(SYS). We can also enter the row vectors of the numerator and denominator coefficients of the transfer function directly into the step function: step(num,den). Example: Plot the unit-step response of the following system in MATLAB: Y (s) 2s + 10 =2 R (s) s + 5s + 4 Solution: Step Response 2. 5 num = [0 2 10]; den = [1 5 4]; SYS = tf(num,den); step(SYS) Amplitude 2 or directly: step(num,den) 1. 5 1 MATLAB will then produce the following plot on the screen. Confirm this plot yourself. 0. 5 0 0 1 2 3 Time (sec. ) 4 5 For a step input of magnitude other than unity, for example K, simply multiply the transfer function SYS by the constant K by typing step(K*SYS). For example, to plot the response due to a step input of magnitude 5, we type step(5*SYS). Notice in the previous example that that time axis was scaled automatically by MATLAB. You can specify a different time range for evaluating the output response. This is done by first defining the required time range by typing: t = 0:0. 1:10; % Time axis from 0 sec to 10 sec in steps of 0. 1 sec and then introducing this time range in the step function as follows: step(SYS,t) % Plot the step response for the given time range, t This produces the following plot for the same example above. 15 6 ECM2105 – Control Engineering Dr Mustafa M Aziz (2010) _______________________________________________________________________________ Step Response 2. 5 Amplitude 2 1. 5 1 0. 5 0 0 2 4 6 8 10 Time (sec. ) You can also use the step function to plot the step responses of multiple LTI systems SYS1, SYS2, †¦ etc. on a single figure in MATLAB by typing: step(SYS1,SYS2,†¦ ) 6. 2. Impulse response The unit-impulse response of a control system SYS=tf(num,den) may be plotted in MATLAB u sing the function impulse(SYS). Example: Plot the unit-impulse response of the following system in MATLAB: Y(s) 5 = R (s) 2s + 10 Solution: Impulse Response um = [0 5]; den = [2 10]; SYS = tf(num,den); impulse(SYS) 2. 5 2 impulse(num,den) Amplitude or directly 1. 5 1 This will produce the following output on the screen. Is that what you would expect? 0. 5 0 0 0. 2 0. 4 0. 6 Time (sec. ) 16 0. 8 1 1. 2 ECM2105 – Control Engineering Dr Mustafa M Aziz (2010) ________________________________________________________________________________ 6. 3. Ramp response There is no ramp command in MATLAB. To obtain the unit ramp response of the transfer function G(s): multiply G(s) by 1/s, and use the resulting function in the step command. The step command will further multiply the transfer function by 1/s to make the input 1/s2 i. e. Laplace transform of a unit-ramp input. For example, consider the system: Y(s) 1 =2 R (s) s + s + 1 With a unit-ramp input, R(s) = 1/s2, the output can be written in the form: Y(s) = 1 1 1 R (s) = 2 ? s + s +1 (s + s + 1)s s 2 1 ? ?1 =? 3 2 ?s + s + s ? s which is equivalent to multiplying by 1/s and then working out the step response. To plot the unitramp response of this system, we enter the numerator and denominator coefficients of the term in square brackets into MATLAB: num = [0 0 0 1]; en = [1 1 1 0]; and use the step command: step(num,den) The unit ramp response will be plotted by MATLAB as shown below. Step Response 12 10 Amplitude 8 6 4 2 0 0 2 4 6 Time (sec. ) 17 8 10 12 ECM2105 – Control Engineering Dr Mustafa M Aziz (2010) ________________________________________________________________________________ 6. 4. Arbitrary response To obtain the time response of the LTI sys tem SYS=tf(num,den) to an arbitrary input (e. g. exponential function, sinusoidal function .. etc. ), we can use the lsim command (stands for ‘linear simulation’) as follows: lsim(SYS,r,t) or lsim(num,den,r,t) here num and den are the row vectors of the numerator and denominator coefficients of the transfer function, r is the input time function, and t is the time range over which r is defined. Example: Use MATLAB to obtain the output time response of the transfer function: Y(s) 2 = R (s) s + 3 when the input r is given by r = e-t. Solution: Start by entering the row vectors of the numerator and denominator coefficients in MATLAB: num = [0 2]; den = [1 3]; Then specify the required time range and define the input function, r, over this time: t = 0:0. 1:6; r = exp(-t); % Time range from 0 to 6 sec in steps of 0. 1 sec Input time function Enter the above information into the lsim function by typing: lsim(num,den,r,t) This would produce the following plot on the screen.

Operating System Memory Management

Question: Discuss about theOperating Systemfor Memory Management. Answer: Introduction An operating system is defined as a software program that helps in enabling the hardware of the computer in order to communicate with the software system. Today, every computer system have Graphical user interface as an operating system that makes the system easier for various operation (Agne et al. 2014). They help in allowing a user to enter the commands by pointing at the objects that appears on the screen. The essay helps in unearthing various concepts of operating system and its history. The assignment also describes the functions of various managers and Basic Techniques of Memory Management and the evolution of memory allocation schemes. Discussion Operating System An operating system is defined as a program which when unloaded in a computer with the help of the boot program, helps in managing all other programs, which are present in the computer system (Belay et al. 2014). The other programs, which are managed by the operating system, are known as application program. The application program uses the operating system by requesting for services with the help of specific application program. The users can interact properly by using a user interface, which includes graphical user interface and command line (Brittain et al. 2014). There are various types of operating system, which includes single and multi-tasking, single and multi- user, distributed operating system and many more. Figure1: Common Features of Operating System (Source: Czakon and Mitov 2014) An operating system performs a number of services for various applications. In a multitasking operating system, a number of programs are running at the same time, it is the task of the operating system to determine the time required for each program before providing a turn to another program (Dawson-Haggerty et al. 2013). The operating system also helps in providing messages to various interactive users about the status or error that may have occurred. All computers platforms whether hardware or software require an operating system therefore an operating system must be built or developed with some specific features in order to meet various requirements of the users. History of Operating System In earlier days, computers are mainly used as calculators in order to perform a single task. The feature of basic operating system was mainly designed after the 1950s (Dixon et al. 2012).The functions of basic operating system includes resident monitor that helps n running various programs in succession automatically in order to speed up the operating system. Operating system was not present in modern as well as complex form until 1960s (Kivity et al. 2014).Many hardware features were added that helps in enabling interrupts, runtime libraries and many more. In 1980s when computer became popular in the market, then operating system was developed with the same concept that was used earlier. In 11940s, the electronic system does not have operating system. Electronic systems at that time were programmed on rows of mechanical switches or with the help of jumper wires. After the invention of general-purpose computers, machine language was introduced in the system (Lin and Zhong 2014). In 1950s a computer was introduced which is helpful in executing a single program at a time. Later on machines were developed with different libraries of programs, which are linked to a user program for assisting various operations including generation of computer codes. Main Task of Managers Memory Manager The main task of the memory manager is to control and co-ordinate the memory of the computer by assigning different sections to various programs that are helpful in optimizing the overall performance of the system (Monaco et al. 2013). In the hardware section, the memory management consists of various components, which includes storing of physical data such as RAM, chips and many more. In the application level, the memory manager helps in ensuring the availability of proper as well as adequate memory for the structures of the data in order to run programs at all time (Nikolaev and Back 2013). The memory manager helps in combining the two tasks, which are related with the recycling and allocation procedure. Process Manager The process manager plays an integral role in operating system. They allocate resources for processing, enabling and exchanging information in order to protect the resources for enabling various types of synchronization among processes (Paczkowski et al. 2015). In order to meet all these requirements and needs, the operating system maintains a specific data structure for a particular process, which helps in describing both the state and resource ownership and they are related with the processes that enables the operating system in order to control the overall process (Rainie and Wellman 2012). The main functions of the process manager includes allocation of resources to various processes, enabling processes in order to share various information, protecting various resources and enabling synchronization for different processes. File Manager The computer systems generally employ secondary storage devices for providing non-volatile storage system for storing various types of programs and data (Walter and Karlsson 2014). The file manager works with the programs and the user data, which are held together in the form of discrete storage systems. They are responsible for keeping space for various files on secondary medium (Agne et al. 2014). The main functions of the file manager include navigation, operations, storage, communication and security. The file manager includes the access and data integrity process under the aspect of security. File managers generally handles the programs or tasks that are related the management procedure of file storage system. They perform functions, which is helpful in automatically alerting the users for carrying out several functions manually. Device Manager Hardware devices help in providing the ability to input as well as output the data from the computer. In order to support various hardware devices, various types of application programming were used (Belay et al. 2014). The applications programming that are used by the device manager. The different application program utilizes System Call API in order to request preset input output request from the operating system. The device manager uses various types of algorithms in order to process the request, which is independent of the device (Brittain et al. 2014). The device managers uses device driver, which is considered as third party software that helps in interacting various devices. Basic Techniques of Memory Management and the Evolution of Memory Allocation Schemes There are four main techniques of Memory Management. The techniques are single contiguous allocation, partitioned allocation, paged memory management and segmented memory management. Single allocation is considered as the most simple memory management technique (Czakon and Mitov 2014). The system that uses single allocation technique uses multitasking procedure by swapping the contents that are present inside the memory for switching among various users. Partitioned technique of allocation helps in dividing the primary memory into several partitions, which mainly consists of the contiguous sections of memory (Dawson-Haggerty et al. 2013). It mainly requires some hardware support in order to prevent the jobs from interfering with different operating systems. Paged allocation helps in dividing the memory of the computer in fixed size units, which is known as page frames (Dixon et al. 2012). The memory management system of the hardware uses physical allocation of memory on a specific page while the addressing space appears to be contagious. Segmented memory is one of the techniques that helps in providing linear as well s contagious memory space (Kivity et al. 2014). They mainly need hardware support in the form of segment table that mainly contains the physical address in the form of size, memory and many more. It helps in allowing better protection for access than any other schemes. There are number of memory allocation schemes, which include single partition allocation, multi-partition allocation, fixed variable size partition, dynamic partitioning and placement algorithm (Lin et al. 2014). Memory allocation can fixed in size or it can change in size for increasing and decreasing the size of the data for accommodating various requirements of change. The memory allocation technique is mainly defined as the process that helps n assigning the block of memory after request (Nikolaev and Back 2013).The allocator receives memory from various operating systems in order to satisfy the request from the smaller blocks. The main memories usually have two partitions, which include low memory and high memory, and the procedure of allocation is divided into single partition allocation and multiple partition allocation. In single partition allocation, relocation register scheme is used for protecting the user processes from each other and in multiple partition allocation; the main memory is divided into number of fixed-sized partitions. Conclusion It can be concluded that operating system is very much necessary in modern computer system. It helps in managing the other programs are generally application programs. The application program utilizes the operating system by demanding for services with the help of detailed application program. The users can cooperate appropriately by using a user interface, which includes graphical user interface and command line. The assignment analyzes that there are number of tasks, which allocated to different managers of the system for its smooth operation. The different techniques of memory management that are described in the assignment are very much useful for the operating system.

The Great Gatsby Book Vs. Movie

The Great Gatsby Book Vs. Movie The Great Gatsby movie vs. book In his movie there were many details that remained loyal to the book. There were some others that were changed slightly, either for filming reasons or for careless from the director. Surprisingly, there were some facts that were left out, that in my opinion were critical for the story and the symbolism on it.The movie showed many things as they are described in the book, and also as many people imagined them. The golden toilette set, the medals and Daisy's picture where shown in his desk just like they were described in the book. Even though that half-eaten sandwich seemed out of place in his desk, since that gives the impression of a "messy" Gatsby, and which he really wasn't.The preparations for Gatsby's parties were almost as the book described them, with the orchestras preparing for the night, the big tents being placed on the garden, the tons of food being brought for the dinner, the grass getting cut before the event and all those preparations Ga tsby had for his parties.The Great Gatsby (1974 film)But they skipped a detail that was discussed in class as very peculiar, the hundreds of oranges that would be brought in the morning and the tons of orange skin that were left after the party.There were also some details that were left the same as in the book, like the sign with the big eyes and the glasses, which is later on seen as a symbolism of God, as discussed in class. The green light across the bay was shown several times to show how Gatsby constantly though of Daisy. Also the childish behavior of Gatsby, while showing his cloths to Daisy was acted very good in the movie. But not everything was perfect in the movie, there were...

How the Kimono represented Japanese tradition and national identity Outline

How the Kimono represented Japanese tradition and national identity and How it has changed overtime - Outline Example As a result, wearing traditional garments such as the Kimono are largely restricted to certain festive or special occasions. Chambers (2007, p. 64) says that Japanese national identity can be established through two primary dimensions: Cultural identities and the distinction between traditional and modern practices. Although worn by men, women and children, the Kimono has always been the marked attire worn by Geishas (traditional dancers) and is also worn by women during their coming-of-age ceremony (held around the age of 20). The goal of characterizing the Kimono as feminine attire can be traced to the cultural renaissance initiated during the Tokugawa era (17th-mid 19th centuries). This persisted among the Japanese elite up until the Meiji period (during the turn of the 20th century) (Mathers, 2005, p. 42). As a result, the role of women in contemporary Japanese society is not dependent on individual choice, but has been built on broad national consensus. Women are looked upon to uphold the family and tradition (as a good mother and wife), unlike men who are supposed to be the decision makers and engage with the external world. Thus, while men prefer western outfits, women are encouraged to adorn the Kimono since its wrapping around the female is a direct representation of national identity. In other words, the wearing the Kimono is widely seen as the differentiating element between Japanese tradition and western cultures. â€Å"In our culture today, a clothes is a part of identity. It is a fashion statement of who we are. This is because we want to be seen in certain ways. Wearing clothes is a practice of showing our subjectivity.† (McRobbie, 1994, p. 128) Nevertheless, the use of Kimono has waned over the decades primarily due to western influences and the high level of maintenance required to clean and preserve the garment. Efforts are often underway to revive the tradition and increase the use of the Kimono

Financial Advisor Career Plan Assignment Example | Topics and Well Written Essays - 3250 words

Financial Advisor Career Plan - Assignment Example For purposes of this career plan, I have used these two occupations interchangeably because these are two closely related entry-level occupations available in the financial services industry (Murdoch, 2005, p. 8). A financial analyst and a financial advisor can work at a commercial or investment bank, a stock brokerage, or for a private financial services company, analyse financial reports for the purpose of providing investment advice, and open up similar career opportunities within the diverse financial services sector. Both occupations also require similar personal and professional qualities such as good interpersonal, analytical, and decision-making skills. This section provides a thorough analysis of the labour market conditions of personal financial advisors, based on the situation in the U.K. where I plan to pursue the first ten years of my professional career. The main reason I chose U.K., more specifically London, is that this place is the generally acknowledged financial centre of the world. A recent article (Economist, 2006) confirmed this and cited geography as one of the main reasons for its success: it is between Tokyo and New York, the financial capitals of Japan and the United States, two of the world's economic superpowers. London's location means that it can trade with both cities every day, starting the day trading with Tokyo and, just as the workday is ending in London it can also start trading with New York. Throughout the day, it can also trade with other countries in Asia (China and Singapore), the Middle East, Europe, and Latin America. It is the ability of London to trade any time with any other country in the world during a normal working day that makes it attractive for financial companies to have a branch in the City, as it is called. This gives us another reason why London has become the financial capital of the world: the number of finance companies based in London is growing. This means that there are more opportunities to find employment and to gain experience because of the high demand for workers and the high supply of jobs available. This is confirmed by a recent study (Murdoch, 2005) of career prospects in the financial services sector. As the Economist (2006, p. 76) article points out, London is an economic cluster in the fast growing field of global financing. Globalisation Another reason why London provides more job opportunities is globalisation. Micklethwait and Wooldridge (2000, p. xvi) called globalisation "the most important economic, political, and cultural phenomenon of our time" characterised by the "integration of the world economy, reshaping business and reordering the lives of individuals, creating social classes, different jobs, unimaginable wealth and, occasionally, wretched poverty." The globalisation phenomenon is exerting pressure on companies and governments to adopt a global strategy, which Stiglitz (2002, p. 9) defined as "the way firms cope with globalisation, the integration of countries and peoples of the world brought about by the enormous

The Criminal Trial Essay Example | Topics and Well Written Essays - 500 words

The Criminal Trial - Essay Example When the trial begins, the prosecution and the defense make their opening statements to the jury. The purpose of these statements are to â€Å"provide an outline of the case that each side expects to prove (Bergman & Barrett, 2009).† The statements only include what the attorneys know that they can present to the jury. The prosecutor then presents its principal case by means of direct examination of prosecution witnesses by the prosecutor themselves. At this time, the defense is allowed to cross-examine the prosecution witnesses; the prosecution is then allowed to re-examine its witnesses. After this procedure, the prosecution is done with presenting their case. The defense is then given the chance to dismiss the charges if they feel that the prosecution failed at providing enough relevant evidence to support a guilty verdict for the person being charged. The judge denies the motion to dismiss, an act that is rare but still seen. It is now the defense’s turn to present their case through means of direct examination of the defense witnesses. The prosecutor is given the opportunity to cross-examine the defense witnesses, followed by a re-examination of the defense witnesses. The defense is then finished presenting their case. The prosecution gives its closing argument, â€Å"summarizing the evidence as the prosecution sees it and explaining why the jury should render a guilty verdict (Neubauer, 2010).† The defense makes a similar closing argument, though they explain to the jury why they should not render a guilty verdict, or, at the very least, declare a guilty verdict on a lesser charge, known as a plea bargain. The prosecution is offered a final closing argument if they wish to argue their plausible evidence that supports a guilty verdict. The jury is given instructions by the judge on what law to apply to the case and how they should carry out their duties. The jury deliberates and attempts to reach a verdict; in most cases, a unanimous agreement

Waarom hebben wij als begeleidster Mevrouw Slesarenko gekozen? Bij het vak Engels waren een aantal leraren/leraressen beschikbaar. We hebben Mevrouw Slesarenko gekozen omdat ze naar onze mening eerlijke en duidelijk beoordeeld. Ze kan makkelijk uitleggen waar dingen verandert moet worden en waar eventueel nog meer informatie bij kan. We zijn blij met deze keuze omdat Mevrouw Slesarenko ons goed heeft begeleid tijdens het profielwerkstuk. INLEIDING Aanleiding Inleiding: Wij hebben dit onderwerp gekozen omdat wij Engels zien als de taal van de toekomst, wat een belangrijke factor van onze keuze is dat wij allebei zonder al te veel problemen deze taal spreken. Engels komt elke dag voor in het dagelijks leven veel reclame en media gebruikt Engels omdat het veel mensen aanspreekt. De vraag is waarom? Waarom spreekt Engels zoveel mensen aan en waarom kunnen de meeste mensen Engels spreken, maar Duits, Frans of Spaans wordt over het algemeen door niet heel veel mensen beheerst. Het is ons doel om goed uit te leggen wat de Engelse taal eigenlijk is en waarom het zo veel word gebruikt door landen die niet als moedertaal Engels spreken. Hieronder staan de onderwerpen waarin wij proberen uit te leggen waarom het Engels zo een belangrijke taal is in onze samenleving. Hoofdstukindeling Geschiedenis van de Engelse taal. In deze paragraaf gaan we de opkomst van het Engels bespreken. Hoe komt het dat Engels zo een belangrijke taal is geworden door de eeuwen heen? Hoe is de Engelse taal in Nederland ontstaan? We gaan vertellen hoe het komt dat de Engelse taal zo belangrijk is geworden in Nederland en waarom we niet meer zonder kunnen. Wat houd het Europees referentiekader in? Het referentiekader is vrij nieuw in Europa. Het Gemeenschappelijk Europees referentiekader voor talen: Leren, onderwijzen, evaluatie is een richtlijn om de vorderingen van leerlingen te beschrijven in Europa. Omdat het ook binnenkort in Nederland ingevoerd zal worden, willen wij dit graag goed uitleggen. Engels als wereldtaal. We gaan bespreken hoe het komt dat de Engelse taal onmisbaar is in de wereld en waarom het zo een grote invloed heeft op de wereld. Engels tegenover andere wereldtalen in Europa. We willen hier bespreken waarom Engels zo een belangrijke taal is vergeleken met andere wereldtalen zoals Spaans, Frans of Duits. Hoe komt het dat Nederlanders zo goed Engels spreken? We willen vertellen hoe het komt dat Nederlanders de Engelse taal zo goed beheersen in vergelijking met andere landen. GESCHIEDENIS ENGELSE TAAL Ontstaan Engelse taal Geschiedenis Oorspronkelijk is het Engels ontstaan uit vele dialecten, die naar Engeland werden overgebracht door kolonisten, aan het begin van de 5e eeuw. De taal werd sterk benvloed door de Oud-Noorse taal van de Vikingen. Door invloed van de Normandiers na de veroverring van Engeland in 1066, veranderde het Oudenengels in het Middenengels. De veranderingen komen grotendeels door het grote gebruik van leenwoorden uit de Normandische woordenschat en het toepassen van de Normandische spellingsregels. Het Engels dat we nu kennen, ontwikkelde zich daarvandaan en ging door met het opnemen van buitenlandse woorden, met name uit het Latijn en Grieks. Het Engels vindt zijn oorsprong in de Germaanse talen die in Groot-Brittannià « gesproken werden..Het is sterk benvloed door het Oudnoords (dankzij de vele Vikingen die er zich vestigden tussen 800-1000), en ook het Frans (na de verovering door de Normandià «rs in 1066) heeft een grote invloed gehad. De grammaticale structuur van het Engels is dus nog steeds overwegend Germaans met nog enkele zinconstructies na die ontleent zijn aan de Romaanse taal. Echter is wel 60% van de totale woordenschat uit van het Engels, ontleent uit het Frans en Latijn. Men noemt het Engels daarom soms ook wel een brugtaal tussen de wereld van de Germaanse en die van de Romaanse talen. Hier nog even de ontwikkelingen binnen het Engels op een rijtje door de eeuwen heen: Oudengels, 7e en 8e eeuw (ook bekend als Angelsaksisch) Middelengels, 12e-15e eeuw, invloed vanuit het Normandisch (een Frans dialect) Nieuw-Engels, 16e eeuw tot heden Opkomst Engels nogwat conclusie of zo ONTSTAAN ENGELSE TAAL IN NEDERLAND Nederlandse taal vroeger. Vroeger sprak iedereen Nederlands. Alleen de rijkere laag van de bevolking sprak Engels doordat ze vaak handels contacten hadden met het buitenland. Nederland is altijd al een handelsland geweest. Mensen gingen naar andere landen omdat daar handel te drijven. Ze namen dan vaak stukjes taal mee terug naar het eigen land. Waarom is Engels een wereldtaal en Nederlands niet? De grammatica van Engels komt uit het Germaans, veel woorden in het Engels komen uit het Romaans. Engels wordt daarom ook wel een brugtaal genoemd tussen de Romaanse en Germaanse talen. De Engelse taal is vanaf de 20e eeuw de grootste en invloedrijkste taal ter wereld. Dit komt door dat Groot-Brittannià « vroeger de baas was in veel gebiedenover de helewereld.Hierdoor ishet Engels in veel voormalige kolonià «n nog steeds de voornaamste gesproken taal. Groot-Brittannià « heeft in die tijd veel kleine eilandjes en landen ingenomen. Maar Engels is ook de belangrijkste taal door de Verenigende Staten, wat vroeger ook een kolonie was, waar heel veel mensen wonen die allemaal Engels spreken. Engels is dus een van de meest gesproken talen ter wereld. Veel minder mensenspreken Nederlands. Nederland had vroeger ook wel Kolonià «n zoals Suriname en Indonesià «. In Suriname wordt nog wel voor een groot deel Nederlands gesproken maar in de andere voormalige kolonià «n helaas niet meer. Groot-Brittannià « had vroeger ook veel kolonià «n over de hele wereld dan Nederland. Vandaar dat Engels een wereldtaal is en Nederlands niet. opkomst Engels in Nederland Nederland is na de Tweede Wereldoorlog bevrijd door voornamelijk Engels sprekende soldaten denk maar aan de Amerikanen, Britten en Canadezen. Dit had een erg positieve invloed op het aanleren van de Engelse taal in Nederland. Veel ontwikkelingen uit het Engelse taalgebied komen ook naar het Nederlandse taalgebied, ontwikkelingen zoals de computer spelen een grote rol. Hierdoor worden veel Engelse begrippen waarvoor (nog) geen Nederlands woord bestaat in de taal opgenomen. Veel Engelse woorden blijven dan ook onvertaald en blijvend gebruikt in de Nederlandse taal. Factoren Belangrijke factoren die er voor hebben gezorgd dat Engels erg belang werd in Nederland zijn: Computers, daarbij moet je vooral denken aan het internet en vele Amerikaanse computerspellen. Immigranten Engelstalige films en boeken Reizen over de wereld werd gemakkelijker. Engels is een vrij makkelijke taal om aan te leren voor veel mensen. De VS en zijn belangrijke invloed over de hele wereld. De invloed van het Engels in Nederland is dan ook erg groot, in Nederland spreken veel mensen Engels als tweede taal. Engelstalig onderwijs in Nederland In het voortgezet onderwijs is Engels een verplicht vak. Voor veel mensen in Nederland is het ook hun tweede taal. Het aantal Engelstaligen in Amsterdam ligt tussen de 50.000 en 100.000 personen en dit aantal groeit sterk. Er leven in de Benelux veel expats die (op hun werk) Engels spreken en vaak hun kinderen ook naar Engelstalig onderwijs sturen. Het Engelstalig onderwijs in Nederland maakt een stormachtige groei door. Op een aantal basisscholen, niet op alle, wordt Engelse les gegeven, voornamelijk aan de hoogste klassen (groep 7 en 8). Het is een vast onderdeel van veel vormen van voortgezet onderwijs. Op sommige scholen wordt Versterkt Engels gegeven. Op een kleine 100 scholen in Nederland wordt tweetalig onderwijs in het Engels en het Nederlands gegeven. Er zijn internationale scholen waar volledig in het Engels les wordt gegeven. Op universiteiten zijn er veel masteropleidingen die Engelstalig zijn. Ook komen er steeds meer Engelstalige bachelor opleidingen. Bij veel opleidingen wordt gebruik gemaakt van Engelstalig lesmateriaal en Engelse namen. Engelstalige televisie in Nederland Door de revolutie in de communicatie is het aantal televisiezenders toegenomen tot meer dan 100 in Nederland. Een groot gedeelte daarvan is ook in het Engels. Bekende Engelstalige televisiezenders in Nederland zijn de British Broadcasting Corporation (BBC) en CNN. Daarnaast wordt er ook veel Engelstalig materiaal uitgezonden met Nederlandse ondertiteling. Anglofobie In Nederland ontstaat er bij sommigen een sterk gevoel van anglofobie (ook wel anti-anglicisme genoemd).[bron?] Dit komt vooral doordat mensen de indruk krijgen dat Engelstaligen zichzelf goed vinden, dat ze een dominante plek innemen of dat ze denken dat ze overal terecht kunnen met hun taal en zelf geen vreemde talen hoeven te leren. Naar de mening van anglofoben wordt er vaak onzorgvuldig omgegaan met het Nederlands. De media bijvoorbeeld gebruiken in hun ogen veel Engelse woorden of vaktermen die lang niet altijd nodig zijn. Dat leidt vaak tot irritaties. Zeker remigranten of immigranten die in Nederland aankomen, ergeren zich vaak aan het taalbeleid van Schiphol, waar borden als trefpunt vervangen zijn door meeting point of reclames in het Engels. Wat vaak ook irritaties oplevert, is dat Engelse beschrijvingen vaak bovenaan vermeld worden terwijl Nederlands de officià «le voertaal is. EUROPEES REFERENTIEKADER betekenis Wat betekent het Gemeenschappelijk Europees referentiekader nou precies? Het Gemeenschappelijk Europees referentiekader voor talen: Leren, onderwijzen en evaluatie is een richtlijn om de vorderingen van leerlingen te beschrijven in Europa. Het is door de Raad van Europa samengesteld als deel van het project Language Learning for European Citizenship tussen 1989 en 1996. Hieronder zullen wij dit nog verder uitleggen. Het Gemeenschappelijk Europees Referentiekader zorgt voor een basis die internationaal gebruikt kan worden voor de uitwerking van lesprogrammas, examens, leerboeken en dergelijke in heel Europa. Het beschrijft wat studenten moeten leren om een taal te kunnen gebruiken voor communicatie en welke kennis en vaardigheden zij moeten hebben om duidelijk te kunnen handelen in een vreemde taal. Verder bevat het referentiekader ook vaardigheidniveaus waarmee de voortgang van studenten levenslang kan worden gemeten. Het Gemeenschappelijk Europees Referentiekader is bedoeld om misverstanden te voorkomen uit de verschillen tussen de onderwijsstelsels in Europa. Door een gemeenschappelijke basis te bieden voor de beschrijving van doelstellingen, inhoud en lesmethoden, vergroot het referentiekader de internationale samenwerking op het gebied van de taal die we vandaag spreken. Het Referentiekader beschrijft ook deelkwalificaties. Deze kunnen worden gebruikt wanneer een beperktere taalkennis is vereist (bijvoorbeeld meer luister- dan spreekvaardigheid) of wanneer er weinig tijd beschikbaar is voor het leren van een derde of vierde taal en wellicht betere resultaten haalbaar zijn door bijvoorbeeld meer te mikken op herkenning dan op onthouden. Algemene maatregelen voor het goed verlopen van het Europees Referentiekader. Voor zover mogelijk zekerstellen dat alle groepen binnen de bevolking toegang hebben tot de middelen om kennis te verkrijgen van de talen uit andere landen en vaardigheden in het gebruik van die talen aan te leren waarmee zij in hun communicatiebehoefte kunnen voorzien. Het niveau van docenten, leerkrachten en studenten op alle niveaus bevorderen, aanmoedigen en ondersteunen om in hun eigen situatie goed en duidelijk de vreemde taal te spreken en te kunnen verstaan. Onderzoeks- en ontwikkelingsprogrammas maken die ertoe leiden dat op alle onderwijsniveaus methoden en materialen worden ingevoerd die geschikt zijn om alle niveaus van onderwijs in staat te stellen voldoende vaardigheden aan te leren zodat ze de vreemde taal goed kunnen beoefenen. Hier zijn een aantal belangrijke factoren die de maatregelen ondersteunen. Je moet: kunnen omgaan met alledaagse zaken in een ander land, en buitenlanders die in hun land verblijven kunnen helpen dat ook te doen; informatie en ideeà «n kunnen uitwisselen met jonge mensen en volwassenen die een andere taal spreken en hun gedachten en gevoelens aan hen kunnen overbrengen; een breder en dieper inzicht kunnen krijgen in de leefwijze en gedachtewereld van andere volken en het begrijpen van de bijhorende cultuur. Het beste is een vreemde taal aan te leren is door: het onderwijzen en leren van taal te baseren op de behoeften, motivaties, kenmerken en bronnen van studenten; zinvolle en realistische doelen zo goed mogelijk tot realiteit te brengen. gepaste methoden en materialen te ontwikkelen; Bij de opleiding Engels maak je beter kennis met het grote aanbod van dialecten in talen, culturen, en literaturen, zoals die nu is en zoals die in de loop van de geschiedenis is gegroeid. Ook leer je om je in correct Engels uit te drukken, zowel schriftelijk als mondeling, en een groot aantal dialecten te verstaan. Hieronder staan de 6 niveaus van het Referentiekader. A Basisgebruiker A1 Doorbraak A2 Tussenstap B Onafhankelijke gebruiker B1 Drempel B2 Uitzicht C Vaardige gebruiker C1 Effectieve operationele vaardigheid C2 Beheersing Voor elk niveau zijn er deze 3 onderwerpen. Begrijpen Luisteren Lezen Spreken Gesproken interactie Gesproken reproductie Schrijven Referentiekader in Nederland Dit Gemeenschappelijk Europees Referentiekader wordt ook gebruikt in de nieuwe Wet Inburgering die in Nederland sinds 1 januari 2007 geldt. Inburgeringsplichtigen moeten sindsdien zorgen dat ze Nederlands leren spreken, lezen, schrijven en verstaan op A2-niveau. Waarom bestaat dit? K Invoeren in NL De rede hiervan is.. WERELDTAAL Engels als wereldtaal Engels vs. Nederlands Conclusie De belangrijkste rede is dus dat Engels wel een wereldtaal is, omdat .. en Nederland is/heeft dat niet. Wereldtaal Engels is al zon twee eeuwen lang de grootste wereldtaal. Er zijn dan ook een groot aantal verschillende varianten aan literatuur in het Engels verschenen. Niet alleen in Engeland zelf, maar ook in de andere onderdelen van het Verenigd Koninkrijk, in Ierland, en in voormalige kolonià «n zoals de Verenigde Staten, Canada, Australià «, Nieuw Zeeland, India, Zuid-Afrika, en het Caribisch gebied. Ook wordt er in al deze gebieden weer een andere variant van het Engels gesproken. Een wereldtaal is een verspreide taal met een aanzienlijk aantal sprekers die internationaal veel wordt gebruikt. Er zijn verschillende definities van een wereldtaal. Ook zijn er verschillende meningen over welke talen er nu eigenlijk bij horen. Algemeen gesproken gaat het om Arabisch, Engels, Frans en Spaans. Het Mandarijn (Chinees) is de meest gesproken taal, maar is eigenlijk alleen bekend in China. Talen als Italiaans, Russisch en Duits zijn twijfelgevallen. Het Nederlands wordt soms de kleinste wereldtaal genoemd, wellicht niet zozeer vanwege het aantal sprekers maar omdat het Nederlands in historisch opzicht bepaalde rollen van een wereldtaal heeft vervuld. Internationaal Engels (ook wel Wereldwijd Engels of Standaard Engels) is het idee dat Engels de wereldtaal voor communicatie is of zal worden, in plaats van de vele verschillende talen die de wereld kent. Eà ©n wereldtaal zou communicatie vereenvoudigen omdat er geen tolken meer nodig zouden zijn. Engels als wereldtaal kan ook de wetenschap ten goede komen, als iedereen Engels spreekt kan er gemakkelijker onderzoek gedaan worden. De inheemse bevolking van oerwouden zou wetenschappers bijvoorbeeld duidelijker uitleg kunnen geven over de natuur. De reden waarom Engels als een wereldtaal wordt beschouwd is simpel. Het is een taal die makkelijk te leren is en die werelwijd door honderden miljoenen mensen als eerste of tweede taal wordt gesproken. Engels is een taal waar men vaak mee te maken krijgt en die overal voorkomt, zoals in games en op televisie (voornamelijk in Nederland). De keuze voor Engels lijkt dus voor de hand liggend, maar er moet wel de bereidheid bestaan om vreemde tale n te leren en deze is vaak niet aanwezig. Alles bij elkaar blijft het Engels toch een taal die op internationaal vlak heel belangrijk is en die in de komende jaren nog belangrijker kan worden. In plaats van Engels zouden ook Spaans en Mandarijn de enkele wereldtaal kunnen worden, alhoewel deze minder kans maken dan Engels omdat ze moeilijker zijn (Mandarijn) of minder verspreid (Spaans). Betekenis Modern Engels, soms beschreven als de eerste wereldwijde lingua franca, is de belangrijkste internationale taal voor communicatie, wetenschap, luchtvaart, entertainment, toerisme , radio, diplomatie en in de zakenwereld. De uitbreiding van de taal vanaf de Britse eilanden over de hele wereld begon tegelijk met de groei van het Britse Rijk, en aan het eind van de negentiende eeuw was de taal werkelijk wereldwijd verspreid. De taal is dominant in de Verenigde Staten en door zijn groeiende economische en culturele invloed en status als wereldmacht sinds de Tweede Wereldoorlog is de positie van de taal wereldwijd versterkt. Een goede kennis van het Engels is een vereiste in een aantal werkgebieden en beroepen zoals geneeskunde en informatica; ten gevolge daarvan spreken ten minste à ©Ãƒ ©n miljard mensen de beginselen van het Engels. Het is ook een van de zes officià «le talen van de Verenigde Naties. Taalkundigen als David Crystal herkennen dat een van de gevolgen van de groei van het Engels (net als andere wereldwijd gesproken talen) is dat de taalkundige diversiteit op veel plekken ter wereld verloren gaat, met name in Australazià « en Noord-Amerika Internationaal Engels Uit Wikipedia, de vrije encyclopedie Ga naar: navigatie, zoeken Internationaal Engels (ook wel Wereldwijd Engels of Standaard Engels) is het idee dat Engels de wereldtaal voor communicatie is of zal worden, in plaats van de vele verschillende talen die de wereld kent.

Engels is tegenwoordig de meest gebruikte taal in internationale betrekkingen. Het is ook van alle talen de meest aangeleerde als tweede taal. Maar is dit zo vanzelfsprekend? Engels de wereldtaal Momenteel kunnen we er niet naast kijken. Engels is dà © wereldtaal. Elk kind van 10 jaar kan naast zijn moedertaal een mondjevol Engels meepraten en passief aardig wat Engels begrijpen. Hoe is deze situatie ontstaan? Het gevolg niet voor de oorzaak nemen Natuurlijk kunnen we zeggen dat het engels ons langs alle kanten overvalt, via liedjes, film, computerspelletjes, computerterminologie, luchthaventaal, enz. Dit is echter niet de reden waarom Engels de wereldtaal geworden is, maar het gevolg. Wat is dan de reden. Eigenlijk kunnen we beter spreken van oorzaak dan van reden. Oorzaak zegt hoe iets er gekomen is, terwijl reden zegt waarom men iets gedaan heeft. Keuze of toeval De eerste vraag die bij ons zal opkomen, is of het Engels de wereldtaal geworden is door keuze of door toeval. We gaan even de mogelijkheden afgaan. Redenen om Engels als wereldtaal te kiezen Gemakkelijk te leren? Uitgebreide woordenschat? Fonetiek? Gemakkelijk te leren? Een zeer rudimentaire kennis van het Engels is gemakkelijk te leren. De spraakkunst is immers zeer eenvoudig. De problemen beginnen pas als je er echt mee bezig bent. De Engelse spraakkunst is inderdaad eenvoudig, maar er is meer uitzondering dan regel. Het Engels is namelijk een heel idiomatische taal. Dat wil zeggen: een taal die niet veel logica hanteert, doch eerder gewoonterecht. Voor iemand die in die taal is geboren, kan dat niet veel problemen opleveren. Wij merken ook niet veel van de onlogische trekjes in het Nederlands. Alleen zijn die in het Nederlands niet zo talrijk als in het Engels. Kortom Engels is gemakkelijk te leren als eerste taal, maar erg moeilijk als tweede of derde taal, tenzij je het natuurlijk niet zo nauw neemt met de exactheid van wat je zegt. Uitgebreide woordenschat? Het Engels heeft een van de grootste verzamelingen woorden van alle talen. Op zich zou dat een voordeel kunnen zijn, omdat dit ruimte geeft voor nuance. Jammer genoeg is de uitgebreide Engelse woordenschat weinig etymologisch onderbouwd. Alvast veel minder dan in het Nederlands, Frans, Duits, Spaans, enz. Dit geeft dus hetzelfde probleem als hierboven: wie het Engels als moedertaal heeft of er de hele dag mee omgaat, zal na verloop van tijd een hele brok van die woordenschat onder de knie krijgen. Wie deze taal echter als tweede of derde taal moet leren en ze niet dagelijks gebruikt, kan zich maar beperkt uitdrukken en wat veel erger is niet alles begrijpen wat de ander zegt of wat hij leest. Fonetiek? Met fonetiek bedoel ik in deze context de relatie tussen wat je schrijft en wat je uitspreekt. De fonetiek is een van de zwakste punten van het Engels. Buiten het Tibetaans, (dit is niet als grap bedoeld) zullen er niet veel talen zijn die zo inconsequent worden geschreven als het Engels. Zelfs voor de native speakers een probleem Als we een Duitse, Nederlandse, Spaanse of Franse tekst op band opnemen, zal iedereen die die taal spreekt hetzelfde horen wanneer de band afgespeeld wordt. Er zijn in dit verband experimenten gedaan met het Engels, die onthutsende resultaten opleveren! Een tekst werd in het Engels op een band opgenomen en dan in stukken geknipt. Fragmenten werden dan afgespeeld voor native speakers en tot de grote ontsteltenis van de onderzoekers hoorden alle luisteraars iets verschillend. Minder dan de helft van de poefpersonen kon exact opschrijven wat de spreker had gezegd. En dit waren dus allemaal mensen die het Engels als moedertaal hadden. Wat zou het resultaat dan geweest zijn, bij mensen die het Engels slechts als tweede taal hadden? De 90/10 verhouding Studies hebben uitgemaakt dat 90% van de Engelse woorden consequent worden gespeld en 10% inconsequent. Het probleem is dat van de frequent gebruikte woorden net omgekeerd 10% consequent wordt gespeld en 90% inconsequent. Dit heeft natuurlijk zijn oorzaak. In vele talen is het zo dat de meest gebruikte woorden een eigen leven gaan leiden en zich vaak onregelmatig gaan gedragen, terwijl de zuinig gebruikte woorden heel gedisciplineerd blijven. Toevalsfactoren bij de opmars van het Engels Factoren die een grote rol hebben gespeeld bij de verheffing van het Engels tot de wereldtaal zijn onder meer: De uitgestrektheid van het voormalig Brits imperium De economische suprematie van de Verenigde Staten van Amerika in de twintigste eeuw Hoe Engeland aan zijn taal komt, weten we wel, maar hoe zit dat met Amerika? De Verenigde Staten zijn uiteindelijk gegroeid uit kolonisten van een aantal landen: De Nederlanden (waaronder ik dus ook het huidige Belgià « reken) Spanje Engeland Ierland Duitsland Scandinavià «, enz. De inheemse volkeren De Afrikaans-Amerikanen Toen het Amerikaanse Congres de officià «le taal voor het nieuwe land ging kiezen, werd er gestemd. De meerderheid stemde voor het Engels. Wat veel mensen niet weten, is dat het maar 1 stem verschil uitmaakte, of het was Duits geweest. Er wordt in sommige publicaties zelfs beweerd, dat dit verschil van 1 stem te maken had met een zieke die zijn stem niet had kunnen uitbrengen. Nu nog is het zo dat als alle Amerikanen hun stamboom maken tot aan hun Europese voorouders, de van afkomst Duitsers de grootste groep uitmaken. Conclusie Samenvattend kunnen we zeggen dat het Engels de wereldtaal is geworden, niet door een beslissing van de wereldbevolking, doch door een samenloop van omstandigheden. De twee belangrijkste factoren hierin zijn de vroegere overheersing van de Britten in alle werelddelen en het feit dat het land dat een groot deel van de twintigste eeuw de sterkste economie van de wereld zou worden, met een voorsprong van 1 stem toevallig het Engels als officià «le taal had gekozen. Even verder denken Als alles anders was gelopen en bijvoorbeeld de Verenigde Naties een onderzoekscommissie zouden inrichten om de wereldtaal te bepalen, zouden andere talen wellicht een belangrijkere rol gespeeld hebben. Gehanteerde criteria zouden wellicht geweest zijn De duidelijkheid van de taal De moeilijkheidsgraad om aan te leren, enz. Welke taal zou het dan geworden zijn? http://kunst-en-cultuur.infonu.nl/taal/15498-engels-de-wereldtaal.html ENGELS TEGENOVER ANDERE WERELDTALEN Andere wereldtalen Ff wat informatie erover.. in welke landen spreken ze vooral spaans bijv. Waarom is Engels dan zo belangrijk en machtig? NEDERLANDS EN ENGELS Taalbeheersing Waarom spreken Nederlanders zo goed Engels.. En in vergelijking met andere landen? Zijn ze beter gemiddeld of slecht? Drukt het Engels het Nederlands weg? Waarom zouden we nog moeite doen om correct Nederlands te gebruiken? Het Engels rukt op en eist overal zijn plaats op. Tickets zijn in presale, pc-games zijn cool en spammen is not done. Bovendien kan je, door Engels te spreken, vaak beter bijblijven in je vakgebied. Spreken we straks nog alleen nog Nederlands in de kroeg? Taalschrift legt deskundigen acht withete stellingen voor. Het Engels sluipt soms heel zichtbaar het Nederlands binnen. Stelling 1: We moeten stoppen met zeuren over de achteruitgang van het Nederlands. Het is niet de eerste keer dat het Nederlands bedreigd wordt, zegt prof. dr. Piet van de Craen. Hij is psychosociolingust aan de Vrije Universiteit Brussel (VUB). In 1788 klaagde Jacobus Verlooy over het feit dat mensen geen goed Nederlands praatten en dat daardoor de hele taal bedreigd werd. Tussen de twee wereldoorlogen ziet men in ons taalgebied het Duits als een bedreiging. En nu maakt men zich zorgen dat het Nederlands dreigt te worden weggedrukt door het Engels Onzin! Het Nederlands is een levende taal. Ze socialiseert kinderen, ze gebruiken die als moedertaal. Het Nederlands fungeert als onderwijstaal. En er wordt in onze taal literatuur geproduceerd. Verder is Nederlands in twee Europese landen een bestuurstaal en een officià «le taal. Bovendien is het Nederlandse de grootste van de kleine talen in Europa en staat ze veertigste op de wereldranglijst van 6 000 talen. Met die bedreiging valt het dus best mee. Stelling 2: Inwonersvan het Nederlandse taalgebied moeten zo vroeg mogelijk eerst Engels leren. Scholen moeten ten minste tweetalig of meertalig onderwijs aanbieden. Piet van de Craen: Ik vind het ontzettend belangrijk om eerst de taal van je buren te leren. Als Nederlandstalige in Brussel is de officià «le taal van de buren het Frans. Het getuigt van culturele ethiek om de taal van je buur te kennen. Wij streven er wel naar meertalig te worden en zelfs zo vroeg mogelijk vreemde talen te leren. Toch kopen wij in Brussel nog geen brood in het Engels. Piet van de Craen: Vlamingen en Nederlanders gaan heel sloppy om met hun moedertaal. In het Sint-Lodewijkscollege van Brugge is Engels de instructietaal voor de vakken chemie, biologie en fysica in de derde graad van het algemeen secundair/voortgezet onderwijs. We hebben daar twee bedoelingen mee, zegt projectcoà ¶rdinator Ingrid Depuyt. Leerlingen de kans geven om vaardiger te worden in het Engels en ze voorbereiden op hoger onderwijs. Vooral voor wetenschap, fysica en informatica groeit het belang van Engels. De tijdschriftartikelen en het vakjargon zijn vaak in die taal opgesteld. Universiteiten en ook hogescholen gebruiken geregeld een Engelstalige cursus. Studenten moeten er dus het Engels machtig zijn. Andere studenten willen tijdens een Erasmusjaar naar het buitenland. Engels is er meestal de instructietaal. Stelling 3: Meer nog dan het oprukkende Engels is het regiol

Macbeth - Power Shifts :: essays research papers

DRAMA OFTEN EXAMINES THE WAYS INDIVIDUALS STRUGGLE TO DOMINATE AND/OR MINIPULATE EACH OTHER. DISCUSS THE TECHNIQUES USED IN ONE OR MORE PLAYS, WHICH DRAW OUT ATTENTION TO THE POWER SHIFTS BWTWEEN CHARACTERS. The text Macbeth by famous playwright William Shakespeare portrays a dramatic power struggle by the careful employment of various literary techniques. "Authority poisons everybody who takes authority on himself" (Vladimir Ilyich Lenin) aptly describes this prominent theme of Macbeth. Techniques include symbolism, emotive language, narrative structure and imagery, which combine to represent the tragic plot portraying the contest between goodness and evil in Macbeth. In the tragedy Macbeth emotive language and soliloquy have been employed to emphasize the struggle for domination between the characters. The main theme of Macbeth, the desire for power and dominance, is appropriately summarized by the following quote: "Vaulting ambition, which o'erleaps itself And falls on the other" (I, VII, 54) The main character, Macbeth, seeks increasing authority influenced by the witches' prophecies, at any cost. Dramatic language has been successfully portrayed Macbeth's desire, through the above quote, whereby the search for power and ambition has been decided. Yet, the result of such ambitious ideals is at risk of resulting in the opposite, being condemnation. Personification in the form of 'Vaulting ambition" and "itself" has been employed to aid to the understanding of the exert, combining with dramatic language which also contributes to the overall impact of the theme. Macbeth lets his "vaulting ambition" rush fate, hence hasten doom. The technique symbolism has also been suitably employed to further enhance Macbeth's struggle for power and dominance, hence the main theme. This may be demonstrated where Lady Macbeth states: "What, will these hands ne'ver be clean...! Here's the smell of blood still..." (V, I, 174) The apparition of blood on Lady Macbeth's hands, which can not be removed, is symbolic of her subconscious revealing her 'wrong doing' in previous sections of the text. Even though Lady Macbeth is no longer influencing her husband towards evil occurrences, the blood is symbolic of her attempts to aid Macbeth's path towards power and dominance. Blood is linked to treachery and murder, hence the emphasis on Lady Macbeth's crimes. The struggle for authority and supremacy has now shifted from Lady Macbeth to her husband, yet her evil deeds are still prominent in he subconscious mind. Light and dark imagery have been portrayed throughout Macbeth to aid to the representation of the main themes of evil opposing goodness.

Paikea’s Determination to Become the Chief

Paikea’s Determination to Become the Chief Whale Rider by Niki Caro is a story about a 12 year old girl who is the true heir to be chief of the tribe but her grandfather, following Maori traditions, believes that the role of chief is to be the first born son of the chief only. Throughout the movie, Paikea is determined to prove that she is the true heir and can be the chief of the tribe. This movie shows how she struggles to get her grandfather’s approval due to his beliefs and the tribe’s tradition which dates back to ancient times.By the end of the story he realizes that Pai is the one and only heir to be chief of the tribe. Throughout the story Paikea must prove to her grandfather that she has courage, determination, and that she has the ability to lead the people of the tribe. Pai cares about her tribe, their culture, and their traditions. Although she is only twelve years old, Pai shows leadership abilities and she is always right by her grandfather’s side. She wants to learn the traditions, so if her dreams of becoming the chief work out, she can pass them on to the rest of the tribe and be a good leader.Paikea is trying to show that she is a strong, courageous girl and she can be a good chief. One side of her wants to prove to her grandfather she can be chief and she wants him to love her even though she is a girl, and the other half wants to prove that a girl can be just as good of a leader as a boy. Paikea shows courage because even though her grandfather has his disbeliefs in her and being the chief, she does whatever it takes to prove to him that she was just as good as any boy in the tribe. Paikea is very determined to learn the ways of her people.She looks through the windows and into the classroom where her grandfather is teaching the boys how to fight since she is not allowed to participate and learn with them. She asks her uncle to teach her how fight like the boys, and soon she becomes very good at fighting and can s ay some chants that only boys are supposed to know. Although her grandfather does not want Pai to learn and know any of the male traditions of the tribe, learns them, and is better than the boys. She is determined to prove to her grandfather that she can be the chief and be better at it than any boy in the tribe can.At the end of the movie Paikea rides the whale out to sea; her grandmother gives the whales tooth to Koro that Pai retrieved from the lake when none of the boys could get it.
