...Unit 10 Caring for Children P3 Safeguarding is a term which is broader than ‘child protection’ and relates to the action the commission takes to promote the welfare of children and protect them from harm. Safeguarding is everyone’s responsibility. Safeguarding legislation and government guidance says that safeguarding means: Protecting children from maltreatment also preventing impairment of children’s health or development. This ensuring that children are growing up in circumstances consistent with the provision of safe and effective care. Taking action to enable all children and young people to have the best outcomes. Physical Abuse Physical abuse may involve hitting, shaking, throwing, poisoning, burning or scalding, drowning, suffocating, or otherwise causing physical harm to a child. Physical harm may also be caused when a parent or carer fabricates the symptoms of, or deliberately induces, illness in a child. If a child often has injuries, there seems to be a pattern, or the explanation doesn’t match the injury then this should be investigated. But you always need to be careful need to ask yourself is it persistent? What is the context? What is the motivation? You can never jump to conclusions, or make assumptions. Some of the symptoms for physical abuse may be: Bruising The bruising is commonly on the head but also on the ear or neck or soft areas - the abdomen, back and buttocks. Defensive wounds are commonly found on the forearm, upper arm, back of the leg...

...P3 – Describe the operation and an application of a solar power source. A solar cell also known as photoelectric cell, is a device that alters light energy into electrical energy. One solar cell creates a really small amount of energy (around about 0.6 volts DC) so they are normally placed alongside each other inside an integrated electrical panel known as a solar panel. We are not completely aware of how sunlight is fully converted into electricity and thus we can only convert a small part of the light energy to electrical energy. The current generation of solar cells convert only a small percentage (12 to 15%) of the light energy from the sun into electrical energy which we can use. A solar cell is based upon the “photo-electric effect” which...

...P3- How is Voting done the in the United Kingdom What is Voting and why is it important? Voting is when you choose a government or a person to run the country or an area. It is important that you vote because this will mean that you will have your say and voting will mean you have control in how your country is run. Voting can be done in many ways and below I talk about the different types of ways you can vote. Different governments will have a different types of ways they can vote and not all governments use the same type of voting system. First past the Post This is where you will elect Members of Parliaments to the House of Commons in the United Kingdom. When you want to vote for a Member of Parliament you have to go voting stations which will be set up in the Whole the of the United Kingdom and you will be given paper where you have to mark an x next to the candidate of your choice. This will then be counted by Volunteers and the Candidate with the highest amount of votes will be elected to represent that city/town. Alternative Vote This is used to elect the majority of chairs...

...For my restaurant its imperative for me to use primary research to conduct my research, therefore all my data I’ve collected is correct and accurate. I will have to this plan in place in order to know how I’m going to conduct. Objectives: -Find out whether people would want a Sicilian restaurant in Northamptonshire. -To find out whether the potential customers would want a classic Sicilian menu or a more modern menu. -I will use social media introduce and get people interested in my restaurant. -Attract new customers from a particular place. -Low food waste and maximize my resources. -Break down the sales in order to maximise the revenue. I am going to collect using a single survey, the reason im going to use a single survey rather than multiple surveys is that if I can include everything in single surveys then there is no need to use loads of different surveys, because it will save me time and money on printing keeping my costs low. I will set out my survey so that as the survey goes on it filters through so that it narrow down the answers. I can also incorporate a time frame for my data. My questionnaire has to narrow down in order to get the best possible responses out of the people I will ask. This means that there should be no questions left to be ask by the people that I questioned. So therefore my survey will be done by me meaning it will be primary data. I think my survey will consist of part qualitative and part quantitative. I am going to present my...

...P3 Planning for Market Research for Cadbury’s New Chocolate Bar. In business it is important for companies to conduct market research in order to find out more about their costumer and to make their strategic decision. For this ask I will be exploring some of the strategies in conducting market research and conducting my own market research for a chosen product. Stages in the Market research Process: This diagram shows the stages of conducting market research. When companies conduct market research a brief is set out to the market research team so that they know what they are doing .the brief tend to be set out in broad term and will consist of clear instruction and what they company want the market researcher to do for example, how many people are eating ice cream and what is their favourite flavours. It will provide details of the organisation, and the project required – for example, to find out how customers are likely to respond to a new type of promotional activity I have created a brief for Cadbury’s new chocolate bar aimed at children. See attached document After the market research team is given the brief, the team will then decide on what resources they will need to conduct the market research. This is important because of the extent of the required research project it is important to know what they are researching the resources they need, and how they are going to do it. It is also important to be clear about the target audience that the research is...

... and Evaluation: Beating the Market ABSTRACT During the period of 2005 to 2010, the market portfolio (P1) and one suggested portfolio (P3) post a positive absolute return of 0.80% and 0.82% respectively which underperformed the active fund portfolio (P2) 0.91%. This report follows various modeling methods in order to back test the performance of the active fund portfolio and compare its performance with that of two other portfolios. The findings indicate that, even though P2 achieves the highest return on the overall performance, the limitations such as the macro environment, the assumptions set, and the Shrinkage method used that accidentally downsizes some valuable stocks in out-‐samples as they are closely correlated are being ignored. By contrast, P3 will probably offer a “middle-‐choice” which will bring a promising and more stable return. 1 Portfolio Modeling and...

...without getting out of their cars. On weekday mornings, arrivals to the drive-up teller window occur at random, with an arrival rate of 24 customers per hour or 0.4 customers per minute. a) What is the mean or expected number of customers that will arrive in a five-minute period? The expected number is of 0.4*5 = 2 customer is a five-minute period. b) Assume that the Poisson probability distribution can be used to describe the arrival process. Use the arrival rate in part (a) and compute the probabilities that exactly 0, 1, 2, and 3 customers will arrive during a five-minute period. The probabilities of the described scenarios are as follows: P0=20e-20! P0=0.135335283 P1=21e-21! P1=0.270670566 P2=22e-22! P2=0.270670566 P3=23e-23! P3=0.180447044 c) Delays are expected if more than three customers arrive during any five-minute period. What is the probability that delays will occur? This probability can be expressed as the probability of more than 3 customers arriving during the five-minute period, which can be computed as following: P(x > 3) = 1 – P(x ≤ 3) P (x > 3) = 1 – 0.85712346 P(x > 3) = 0.14287654 Thus, there is a 14, 29% probability of expected delays in five-minute period. Problem 3 Use the single-server drive-up bank teller operation referred to in Problems 1 and 2 to determine the following characteristics for the system: Using arrival rate and service rate PER MINUTE a) The probability that no customers are in the system ...

...Chapter 6: CPU Scheduling • • • Basic Concepts Scheduling Criteria Scheduling Algorithms Operating System Concepts 6.1 Basic Concepts • Maximum CPU utilization obtained with multiprogramming. • CPU–I/O Burst Cycle – Process execution consists of a cycle of CPU execution and I/O wait. – Example: Alternating Sequence of CPU And I/O Bursts – In an I/O – bound program would have many very short CPU bursts. – In a CPU – bound program would have a few very long CPU bursts. Operating System Concepts 6.2 1 CPU Scheduler • The CPU scheduler (short-term scheduler) selects from among the processes in memory that are ready to execute, and allocates the CPU to one of them. • A ready queue may be implemented as a FIFO queue, priority queue, a tree, or an unordered linked list. • CPU scheduling decisions may take place when a process: 1. Switches from running to waiting state (ex., I/O request). 2. Switches from running to ready state (ex., Interrupts occur). 3. Switches from waiting to ready state (ex., Completion of I/O). 4. Terminates. • Scheduling under 1 and 4 is nonpreemptive; otherwise is called preemptive. • Under nonpreemptive scheduling, once the CPU has been allocated to a process, the process keeps the CPU until it releases the CPU either by terminating or by switching to the waiting state. Operating System Concepts 6.3 Dispatcher • Dispatcher module gives control of the CPU to the process selected by the short-term scheduler;...

...CPU SCHEDULINGCPU scheduling in UNIX is designed to benefit interactive processes. Processes are given small CPU time slices by a priority algorithm that reduces to round-robin scheduling for CPU-bound jobs.The scheduler on UNIX system belongs to the general class of operating system schedulers known as round robin with multilevel feedback which means that the kernel allocates the CPU time to a process for small time slice, preempts a process that exceeds its time slice and feed it back into one of several priority queues. A process may need much iteration through the "feedback loop" before it finishes. When kernel does a context switch and restores the context of a process. The process resumes execution from the point where it had been suspended.Each process table entry contains a priority field. There is a process table for each process which contains a priority field for process scheduling. The priority of a process is lower if they have recently used the CPU and vice versa.The more CPU time a process accumulates, the lower (more positive) its priority becomes, and vice versa, so there is negative feedback in CPU scheduling and it is difficult for a single process to take all the CPU time. Process aging is employed to prevent starvation.Older UNIX systems used a 1-second quantum for the round- robin scheduling. 4.33SD reschedules processes every 0.1 second and recomputed priorities every second. The round-robin scheduling is accomplished by the -time-out mechanism, which tells...

...1. Deadlock (“deadly embrace”) is a system-wide tangle of resource requests that begins when 2 or more jobs are put on hold. • Each job is waiting for a vital resource to become available. • Needed resources are held by other jobs also waiting to run but can’t because they’re waiting for other unavailable resources. • The jobs come to a standstill. • The deadlock is complete if remainder of system comes to a standstill as well. • The resources can be categorized into physical and logical resources. The physical resources are printer, disk drive, cpu, memory, scanner etc. The logical resources are files. • Deadlock is more serious than indefinite postponement or starvation because it affects more than one job. • Because resources are being tied up, the entire system (not just a few programs) is affected. • Requires outside intervention (e.g., operators or users terminate a job) to resolved the deadlock. 2. Seven Cases of Deadlocks Case 1 Deadlocks on file requests Case 2 Deadlocks in databases Case 3 Deadlocks in dedicated device allocation Case 4 Deadlocks in multiple device allocation Case 5 Deadlocks in spooling Case 7 Deadlocks in disk sharing Case 8 Deadlocks in a network Case 1: Deadlocks on File Requests | |If jobs can request and hold files for duration of their...
