Mentorship and work based learning and assessment Essay

Mentorship and work based learning and assessment - Essay Example The whole process of this developmental and assessment framework is required to be supported and assessed by mentors. The midwifery mentors who have additionally qualified to be sign-off mentors as part of their mentorship qualification programme would make the final assessment of practice, and after the assessment, if the registrant qualifies the NMC standards, they would be recommended to be registered (Nursing and Midwifery Council, 2004). To be able to do this, NMC has further designed the framework in such a way that if the outcomes are met within the rigorous provisions of accountability, the registrant midwives will be qualified to be registered. The domains in this framework are establishing effective working relationship, facilitation of learning, assessment with rigorous accountability, evaluation of learning, more importantly creating an environment of learning, establishing context of practice, promoting evidence-based practice, and inducing leadership. This framework wil l be suited for working in the modern healthcare, and there would be a perspective of inter-professional learning (Nursing and Midwifery Council, 2006). Furthermore, this has a close correlation with the career pathways of the midwives due to the fact that NHS has launched KFC scheme as indicators of terms and conditions of service for their employees (Nursing and Midwifery Council, 2006b). Career pathways in midwifery is considered as part of the new pay and career structure that have been developed in Agenda For Change, and this has been linked to the Knowledge and Skills framework. The Agenda For Change is a career framework for the NHS employees that include the midwifery professionals (UKCC, 1999). The KSF in turn is a framework to assess the progress and development of the staff within the pay bands. This needs a modification of the professional demarcations and

Contract law - Essay Example 20,000 to be paid in instalments related to the work completed. The plaintiff got into financial difficulties because the price was too low and he did not supervise the work properly. He had received over 80 per cent of the price but still had far more than 20 per cent of the work to do. The defendants were liable to a penalty clause in the main contract if the work was not completed on time. They were aware of the plaintiff’s difficulties and that the price was too low. They met him and agreed to pay him an extra ?10,300 at ?575 per flat to ensure that he continued with the work and completed on time. The plaintiff completed eight further flats and received a payment of ?1,500. He stopped work and sued for the money he alleged to be owing. The defendants denied liability and, in particular, that they were liable to pay any part of the additional ?10,300 because their agreement to pay it was not supported by any consideration. The judge held that the plaintiff was entitled to eight payments of ?575, less certain deductions. The defendants appealed. â€Å"My understanding of the meaning of the requirement that ‘consideration must move from the promisee’ is that such consideration must be provided by the promise, or arise out of his contractual relationship with the promisor. It is consideration provided by somebody else, not a party to the contract, which does not ‘move from the promisee’†¦Ã¢â‚¬ ¦but it is, of course, not the situation in the present case. Here the benefits to the defendants arose out of their agreement of April 9, 1986 with the plaintiff, the promise.(Glidewell L.J in Williams v Roffey Bros.[1990]) The judge(Glidewell L.J) further concluded that:† I repeat, therefore, my opinion that the judge was, as a matter of law, entitled to hold that there was valid consideration to support the agreement under which the defendants promised to pay an additional ?10,300 at the rate of ?575 per flat. For these rea sons I would dismiss this appeal† In answering the question as to whether promissory estoppel could have been of raised or whether it could have added relevance to Williams v Roffey Brothers, the answer is no, because of the limitations on the doctrine of promissory estoppel. It may be of paramount importance to find the relationship between consideration and promissory estoppel. Consideration originated simply as an indication of the need for a reason for enforcing a promise or obligation, such as the fact that the promisee had given something to the promisor in expectation that the promise would be fulfilled(Atayah, 1986). The rigid set of rules requires that there must be benefit and detriment, that past consideration is no consideration; that consideration must be of economic value; and that gratuitous promises will not generally be enforced. The doctrine of promissory estoppel on the other hand, derives from Lord Denning’s decision in Central London Property Trust Ltd v High Trees Ltd[1947] KB 130. The doctrine gives rise to situations in which a contract can in effect be varied without there being consideration. The facts are that by a lease under seal made on September 24, 1937, the plaintiffs, Central London property Trusts Ltd, granted to the defendants High Trees House Ltd, a subsidiary of the plaintiff company, a tenancy of a block of flats for the term of 99 years from September 29, 1937, at a ground rent of ?2, 500 a year.

Ecological Concepts Essay Example for Free

Ecological Concepts Essay Ecology is the study of the relationship of between organisms and their environment, including both the living and nonliving compounds. Some of the ecological concepts include succession, energy flow between trophic levels, limiting factors, and carrying capacity. First, succession is a change in species structure of an ecological community over time. Over time species in the community become more and more abundant and may not be present at all one day. Also, sometimes new species might invade the community from nearby ecosystem. Ecologic successions occur as a result of drastic change in the environment or species inability to reproduce or grow in a particular environment. There are two types of successions primary and secondary. Primary succession is when an area that was not occupied previously is occupied by a new community. Secondary succession starts where natural vegetation is disrupted by humans, animals, or natural forces. Examples of ecological succession are fires, wind storms, floods, earthquakes, tornados, and forest fires. Energy flow between trophic levels is another ecological concept. Trophic levels are the feeding position in a food chain. This food chain involves primary producers, herbivores, primary carnivores, and more. Plants are producers and in the first trophic level, herbivores form the second level, and carnivores from third and fourth trophic levels. As only small amount of energy is transferred to the higher level there are fewer organisms in higher levels. Limiting factors is the third ecological concept. Limiting factors limit populations from growing any larger than they already are. There are two types of limiting factors Abiotic and biotic. Abiotic factors are nonliving components that affect living organisms and biotic factors are living components. For example 50 foxes can live in an environment that has enough food, water, and space for 60 foxes, but no more than 60 foxes could live there. Lastly, carrying capacity is one the ecological concepts and is the population size of the species one environment can support. Food, water, habitat, and space are the factors that affect carrying capacity. For xample environment could have enough water for the community but not have enough space or food. Best example of carrying capacity is predator-prey relationship. For example in the Isle Royale National Park moose would overgraze the vegetation if wolves did not eat them, and without moose wolves would starve. Overall, these ecological concepts help up understand relationships between one species to another and to the environment they all live in. Also these concepts show how might changes in the environment affect species that live in it.

Phase Interpolator Pll In Simulink Computer Science Essay

Phase Interpolator Pll In Simulink Computer Science Essay Phase Locked Loops (PLLs) is a negative feedback system that matches the output frequency to the input frequency. Many applications utilize PLLs such as: frequency synthesizers, skew cancellation, reference clean-up, and clock-data recovery [1]. For frequency synthesizers, the goal is to generate a clock at a higher speed to that of a slower reference clock. For example, generating a 1 GHz signal from a 100 MHz reference signal. This is a common goal for many optical applications. For example, current work performed by AOSense, a leading research and development company in atomic-level sensing requires clock frequencies well into the hundreds of megahertz and even into the gigahertz range. For this reasons, PLLs, such as the HMC698LP5 from Hittite Microwave are commonly used in their designs. standard pll design A basic PLL consist of four main building blocks; Phase Frequency Detector (PFD), Charge Pump (CP), Low Pass Filter (LPF), and Voltage Controlled Oscillator (VCO). Figure 1 is a block diagram of a basic PLL. http://madfeekree.files.wordpress.com/2010/11/basic-pll-block1.png?w=614 Figure 1. Basic PLL Block Diagram [2] The PFD detects any differences in phase and frequency of the reference and feedback signals and generates an appropriate Up or Down signal. These signals are then passed to the CP, in which, the CP sources current into the loop filter (Up signals) or sinks current from the loop filter (Down signals). The LPF converts the signal into an analog voltage for the VCO, in which the VCO outputs a clock at either a higher faster or slower frequency based on the UP DOWN signals generated by the PD. This process is repeated until the output frequency of the VCO properly matches that of the reference frequency. These blocks were constructed and simulated in MATLAB R2112a Simulink. A. Phase Frequency Detector As previously stated, PFD are devices that measures the difference between the reference and feedback clocks. There are two commonly used phase detectors: linear and binary. A linear phase detectors output is a pulse signal with a varying width. When the feedback signal is severely out of phase with the reference signal, the pulse width is larger compared to when the two signals are close to being similar. In contrast, a binary (bang-bang) phase detectors output is a fixed pulse width. This binary output signifies if the feedback signal arrived early or late compared to the reference signal. In this design, a modified version of a linear phase frequency detector was implemented in Simulink, as depicted in figure 2. This PFD generates a logic high for the UP signal when the feedback signals rising edge arrives ahead of the reference signals rising edge for the length of the difference. Similarly, when the feedback singals rising edge arrives after the reference signals rising edge, a logic high is given for the DOWN signal for the duration of the difference. M:SJSUEE 227ProjectReport PicturesFigure 2 PFD.png Figure 2. Phase Frequency Detector Model Applying a test signal to both the reference and variable (feedback) inputs and adjusting the feedback signal with some delay, demonstrates the proper functionality of the PFD. This is illustrated in figure 3. The plot is as given from the top down: UP, DOWN, Reference, and Variable CLK. The UP and DOWN signals are then fed to the charge pump, which directs the loop filter to increase or decrease in voltage, signifying an increase or decrease of the VCO output signal. But first, a discussion on the charge pump and its modelling is in order. M:SJSUEE 227ProjectReport PicturesFigure 3 PFD Test.pngFigure 3. PFD Test Results B. Charge Pump The charge pump block in figure 1 is designed to convert the UP and DOWN signals into current for the loop filter. When the UP signal is logic high, the charge pump will source current to the loop filter and when the DOWN signal is logic high, the charge pump will since current from the loop filter. A circuit representation of a charge pump is given in figure 4 below. From this representation, several key design challenges are noticed. Such as proper current matching from both I1 and I2, parasitic capacitance from the two current sources, and leakage current into and out of the loop filter. M:SJSUEE 227ProjectReport PicturesFigure 4 CP.png Figure 4. Charge Pump Circuit A Simulink model of a charge pump is given in figure 5. Notice how the DOWN signal is subtracted from the UP signal and then fed into a gain of 0.001. This gain value represents the current of the two current sources. The delay representsrepresents the current of the two current sources. The delay represents the capacitor, Cp, in figure 4. M:SJSUEE 227ProjectReport PicturesFigure 5 CP Block.png Figure 5. Charge Pump Model Simulating the charge pump model should show a slowly increasing value as long as the UP signal is high more often than the DOWN signal. Figure 6 below shows such a scenario as the CP_Out signal slowly ramps up. This signifies that the VCO will speed up to force the reference signal to catch up to the data signal. M:SJSUEE 227ProjectReport PicturesFigure 6 CP Test.png Figure 6. CP Test Results C. Loop Filter A loop filter is an entirely passive component device and consist of two capacitors and a resistors as illustrated in figure 7. The loop filter has two branches, the integral path and the proportional path. The integral path is the C2 branch, while the proportional path is the C1 and R branch. As the name implies, the loop filter filters high frequency noise spurs caused by sampling, but this also adds a pole at 1/RC2 [1]. A resistor in the loop filter provides an isolation phase correction from frequency correction. M:SJSUEE 227ProjectReport PicturesFigure 7 Loop Filter Circuit.png Figure 7. Loop Filter Circuit A simulink model of a loop filter is given in figure 8 below. The input to the loop filter is connected to the output of the charge pump. The purpose of the loop filter is to take a current and convert it into a voltage, called the control voltage of the VCO. M:SJSUEE 227ProjectReport PicturesFigure 8 Loop Filter Block.png Figure 8. Loop Filter Model Simulating the loop filter in Simulink gave the plot in figure 9. Re-examining this figure, there may be a an error in the loop filters output as its a sawtooth waveform. This will be compared to the VCO output plot for proper functionality in the next section. Figure 9. Loop Filter Test Results D. VCO The final block in figure 1 is the VCO block. Theres a slight modification to the VCO block compared to that in figure 1 due to the future use of phase interpolation. Due to this, a phase generator block was required. This phase generator block is given in figure 10. M:SJSUEE 227ProjectReport PicturesFigure 10 Phase Generator Block.png Figure 10. Phase Generator Model The purpose of the phase generator block is to allow various phases for the phase interpolation PLL in the forthcoming section. For this, the signal is limited to 360 degrees and various phases are generated as illustrated in figure 11. This is the final design of the VCO. M:SJSUEE 227ProjectReport PicturesFigure 11 VCO Block.png Figure 11. VCO Model A common VCO has a single output, known here as CLK_0. However, due to the use of phase interpolation in the second half of this PLL design, 3 other phases were generated. Each phase separated by 90 degrees. The feedback to the PDF is derived from CLK_0 signal that is passed through a relay that generates a clock signal from a sinusoidal signal. The final PLL design for the first potion is given in figure 12. M:SJSUEE 227ProjectReport PicturesFigure 12 PLL Block.png Figure 12. PLL Design Phase 1 Testing of the pll Testing of the PLL consisted of a pulse generator at the reference clock input. This signal was set to 50 Hz is mentioned in [3]. Figure 13 is a plot of the VCO output (CLK_0). The plot shows that in the beginning, the VCO is attempting to lock and after about 30 seconds, the system locks onto the frequency. M:SJSUEE 227ProjectReport PicturesFigure 13- PLL Test Results.png Figure 13. PLL Phase 1 Test Results phase interpolator design A. Theory Behind Phase Interpolators Phase Interpolators (PI) is a modified version of a PLL. PIs function by taking a weighted values and multiplying and adding them to two signals shifted in phase at the same frequency. These weighted values are call alpha and beta. Beta equals 1 minus alpha as given in equation (1) (1) Where, B. Binary Phase Detector The phase detector used in the PI loop has been modified to act as a bang-bang phase detector instead of a linear phase detector. A modified version of the bang-bang phase detector [4] was used. This modified bang-bang phase detector is given in figure 13i. M:SJSUEE 227ProjectReport PicturesFigure 13i- BBPD Block.png Figure 13i. Modified Bang-Bang Phase Detector A bang-bang phase detector is different from a linear phase detector since the output signals are fixed pulses and they signify if the feedback clocks rising edge is early or late. Those early and late signals are then fed into a charge pump, which tells the VCO (by means of a loop filter) to go faster or to slow down. Simulating this modified version of a phase detector was performed in Simulink. The feedback (reference) signal was delayed compared to the DATA clock. This implies that the phase detector outputs a logic high for the LATE signal, in which it does. M:SJSUEE 227ProjectReport PicturesFigure 13ii- BBPD Test.png Figure 13ii. Bang-Bang Phase Detector Test Results D. Quadrature Clocks Quadrature Clocks are clocks that are separated by 90 degrees. The model to accomplish this was given in figure 11 of the VCO. Testing this with a simple pulse generator input signal provided the plots in figure 14. These plots show four signals that are 90 degrees out of phase with one another. M:SJSUEE 227ProjectReport PicturesFigure 14- Quad Phases.png Figure 14. Quadrate Phases Reading from the top of figure 14 to the bottom, the phases are as follows: 0, 90, 180, and 270 degrees. E. Counter To ensure the entire 360 degrees of phases are covered, as given in the VCO, a counter was implemented. For this simulation, an 8-bit counter was used. This implies that for 360 degrees and an 8-bit counter, each degree represents 1.41 degrees of resolution. The importance of this is related to the unit circle. For a count from 0-255, each 64 counts represents a phase shift of 90 degrees. A simple counter was constructed in Simulink using a just three blocks as shown in figure 15. M:SJSUEE 227ProjectReport PicturesFigure 15- Counter.png Figure 15. Counter Model F. Alpha, Beta, and MUX Values To determine the alpha, beta, and the MUX values, a model was created in Simulink. From section C, an 8-bit counter was created. Of these 8-bits, bits 0-5 represent the alpha bits and bits 6-7 represent the MUX bits. These bits were extracted and then the alpha and the beta values were obtained as mentioned in section A and equation (1). A Simulink model is given in figure 16. M:SJSUEE 227ProjectReport PicturesFigure 16- Alpha Beta Mux.png Figure 16. Alpha, Beta, and MUX Extractor Testing the model in figure 16 revealed an interesting note. This model was taken directly from [3] and when a simple test of this block was performed, the MUX bits appeared to be out of the ordinary. It was expected that the MUX values would range from 0-4 as two bits were extracted, giving a four step ramp. However, the four step ramp ranged from 0-192. This is shown in figure 17. The next section discusses the MUX switching and this is why the issue was noticed. Because of this, this discussion will take place in the next section. M:SJSUEE 227ProjectReport PicturesFigure 17- Alpha Beta Mux Test.png Figure 17. Alpha, Beta, and MUX Test Results G. MUX Model Since a PI requires the use of two different phases simultaneously, a MUX is required to give the proper signals. In Simulink, a MUX was generated using multiport switch components. The model is given in figure 18 below. As there are four inputs, the select line is required to be a value of 1, 2, 3, or 4 in order to properly select the desired line. The select line is driven by the 2-bit MUX value that was obtained in the previous section, F. This implies that the MUX values should be a 1, 2, 3, or 4 value and not the values that are shown in figure 17. The four steps are correct, but further work is need to properly generate the appropriate select lines. Due to the MUX select lines not functioning properly, the final PI PLL design was unable to be properly tested. A solution to this problem is to write a piece of code that reads the MUX line and then determines the proper, 1, 2, 3, or 4 value. M:SJSUEE 227ProjectReport PicturesFigure 18- MUX Model.png Figure 18. MUX Model H. Finall PLL Block and Testing The final design of the complete PLL with the phase interpolator PLL is given in figure 19. As stated in MUX Model section, the MUX line had a critical error that prevented the PLL from being properly simulated. This error was due to the MUX select lines not being of the proper value. If given more time, code would be implemented to resolve this problem or the use of Simulink blocks to generate the proper values for the select lines. M:SJSUEE 227ProjectReport PicturesFigure 19- Final PLL Block.png Figure 19. Final PLL Design with PI For simplicity do to time constraints, a simple test was performed on the final design. Since the MUX select lines are not function properly, a constant value was fed into the select lines to manually pick the phases. When the select line was set to 1 for both, the graph in figure 20 was generated. M:SJSUEE 227ProjectReport PicturesFigure 20- Final PLL Test MUX 11.png Figure 20 PI Output/Feedback Pre Relay Figure 20 shows that the PLL is working to a degree. Unfortunately, it fails to be properly tested. Conclusion PLLs are commonly used devices in a wide range of applications. In this design, a phase interpolator version of a PLL was examined. Although the complete model was successfully constructed in Simulink, the final design was unable to be properly tested. This was due to the malfunction of the MUX select lines that prohibited the simulation to run. A quick work around was implemented, which meant the manual adjustment of the MUX select lines.

A Student According to Ted Kooser Essay -- poem analysis and review

Ted Kooser’s poem â€Å"Student† underlines how the life of a student truly is. As we were discussing our insights of the poem â€Å"Student† by Ted Kooser, Omar Mejia mentioned how he found a comparison with a turtle in the poem. I have imagined a baby turtle and their journey when is born and running trying to reach the sea. Imagine the life of a turtle that their life starts in the sand and after its journey to their future begins. Somehow I agree with this idea. As I imagined the complicate and hard life that a sea turtle must have I also recall how the life of a student could be as hard and complicate. Sometimes the life of a student can be complicated, busy, confusing, struggling, happy, sad, depressing, demanding and joyful and so on and so forth. The life of a student is a life full of responsibilities Kooser first mentions the best friend of a student â€Å"The green shell of his backpack†(Line 1). A backpack that will accompany the student during most of the studying time in which a student will carry their books, notes maybe a computer. As of me I have my backpack most of the time at s...

Philosophy of Education Essay -- Philosophy of Teaching Education Teac

Philosophy of Education I began my college education in 1987. I attended two full years and one part-time year before accepting a position with an engineering firm in 1992. I was employed there for the next nine years and was promoted three times. Even though this was a good stable career, I was not satisfied. I have always wanted to be a teacher. I never gave up hope and continued to take a class when I could. In the fall of 2001, I had the opportunity to work part-time and finish my degree. I am so excited to achieve my lifetime goal of becoming an educator. Almost everyone has a teacher they remember. Some are remembered for being a positive influence. Others are remembered for negative traits they exhibited. Often times a student never forgets the impact a certain teacher had on the outcome of their lives. My goal is to be the teacher who puts forth the extra effort for my students so they may achieve all their dreams. I would like to be the teacher students remember, not because I was nice or made things fun, but because they were challenged to learn. Within my classroom, I hope to create a nurturing environment so each child can learn to his or her fullest potential. Being a teacher carries so much responsibility. In addition to teaching each child effectively, you are also a role model and example in your classroom. Children model behavior they are exposed to at home as well as at school.

Same Person collects daily fees and deposits the cash and files the wavier forms There should be one person (A) that has visitor fill out the forms and files them, also keeping a tally of the number each day. And a second person (B) collects the cash and deposits it into the lock box. The accountant deposits the cash at the bank and makes the journal entry The manager at the end of the night could deposit the cash, and the next morning the accountant could make the journal entry. No one checks the number of wavier forms filled out against the amount of cash deposited The accountant should also check the amount of waiver forms filled out against the amount of cash deposited to make sure amount deposited is equal to the number of visitors paying a fee Problem 9-15 Identify one or more control procedures (either general or application controls, or both) that would guard against each of the following errors or problems. a.) Leslie Thomas, a secretary at the university, indicated that she had worked 40 hours on her regular time card. The university paid her for 400 hours worked that week. Payroll clerk reviews all inputs before posting, and then the accounting supervisor reviews all checks for reasonableness before sending them out. b.) The aging analysis indicated that the Grab and Run Electronics Company account was so far in arrears that the credit manager decided to cut off any further credit sales to the company until it cleared up its account. Yet, the following  week, the manager noted that three new sales had been made to that company—all on credit. Computer control to disallow issuing new sales on credit to customers should be programmed into the system. c.) The Small Company employed Mr. Fineus Eyeshade to perform all its accounts receivable data processing. Mr. Eyeshade’s 25 years with the company and his unassuming appearance helped him conceal the fact that he was embezzling cash collections from accounts receivable to cover his gambling losses at the race track. Employees are required to take vacation and they should be cross-trained to cover each other’s jobs when they are out. d.) The Blue Mountain Utility Company was having difficulty with its customer payments. The payment amounts were entered directly into a terminal, and the transaction file thus created was used to update the customer master file. Among the problems encountered with this system were the application of customer payments to the wrong accounts and the creation of multiple customer master file records for the same account. They should be matching the invoice number and account numbers; this review should catch the error. Another control is the customers reviewing their statements to make sure that they are not being over charged, ect. e.) The Landsford brothers had lived in Center County all their lives. Ben worked for the local mill in the accounts payable department, and Tom owned the local hardware store. The sheriff couldn’t believe that the brothers had created several dummy companies that sold fictitious merchandise to the mill. Ben had the mill pay for this merchandise in its usual fashion, and he wrote off the missing goods as ‘‘damaged inventory.’’ Access control to create new vendors, and vendor approval procedures is a good control. Problem 9-16 Identify one or more control procedures (either general or application controls, or both) that would guard against each of the following errors or problems. a.) A bank deposit transaction was accidentally coded with a withdrawal code. Having an input that verified what type of transaction was being inputted by personal. Also, at the end of the night count would reveal this problem because there would be extra money from the deposit in the drawer. b.) The key-entry operator keyed in the purchase order number as a nine-digit number instead of an eight-digit number. Input controls through the database form that  limits the number of digits of 8 that can be keyed in by the operator. c.) The date of a customer payment was keyed 2001 instead of 2010. Input control that checks the validity of the data keyed in. If the proper perimeters where set with the application anything that fell short would not be processed until the problem was resolved. d.) A company employee was issued a check in the amount of −$135.65 because he had not worked a certain week, but most of his payroll deductions were automatic each week. Edit programs could perform edit checks that would result in an error for negative amounts before issuing checks to employees. This is done by test of sign and the system would kick back the transaction for correction before issuing the check. Payroll deductions should never be programmed to a specific number each we ek because this does not allow for changes in the number of hours worked and will always result in a mistake. e.) A patient filled out her medical insurance number as 123465 instead of 123456. Edit programs could detect this input error by matching the information with the master file if the correct perimeters were set. f.) An applicant for the company stock option plan filled out her employee number as 84-7634-21.The first two digits are a department code. There is no department 84. Edit programs could detect this input error by matching the information with the master file if the correct perimeters were set. Once it’s noticed the employee would not be able to continue until they inputted their correct employee number. g.) A high school student was able to log onto the telephone company’s computer as soon as he learned what telephone number to call. There should be a user name and password to access any company’s computer. h.) The accounts receivable department sent 87 checks to the computer center for processing. No one realized that one check was dropped along the way and that the computer therefore processed only 86 checks. Set up a checksum to check the number of checks sent against the number of checks received. They would then realize that they are missing a check and can look for it or get another one and void out the one that was dropped.
