Assessment Brief

Complete the following tasks in the form of a report. Your answers should include formal references, diagrams where appropriate and a detailed bibliography.

Learning Outcomes Assessed 1 Compare and contrast Quality of Service methods and their requirements. 2 Investigate traffic engineering and service differentiation into the internet 6 Critically analyze the Multi-Protocol Label Switching technology and its QoS capabilities.

TASK 1 – QUEUEING & SHAPING (40% WEIGHTING) [LO1]

QoS parameters are determined by an associated SLA. To ensure that the traffic being routed by the ingress router doesn’t break the terms of the SLA, packets need to be classified and managed to ensure they exit the router in a controlled manner (Performance Tuned). There are a number of methods that can be used to accomplish this with the main methods being:  • Packet Classification • Queuing • Shaping • Admission Control (active and passive) With regard to the Performance Tuning methods listed above, discuss how these are implemented within a network to ensure that QoS as determined by an SLA, can be met.

TASK 2 – QOS DELIVERY (35% WEIGHTING) [LO2]

When traffic exits the ingress router, there are a number of architectures that can be implemented to ensure that the QoS compliant delivery of Voice, Video or Data packets.

For delivery of packets between ingress and egress edge router interfaces three important technologies can be implemented to ensure that QoS are met these are:  • Integrated Services • Differentiated Services • RSVP Evaluate these methods, their operation and requirements for achieving QoS, and discuss how these technologies can be used in conjunction with each other to ensure QoS delivery.

TASK 3 – MPLS (25% WEIGHTING) [LO3]

To ensure QoS can be achieved at ISP level, label switching technologies are implemented. However due to the behaviour of various protocols used by ISPs (IPv4, IPv6, Ethernet, PPP, OSPF etc.), MPLS was introduced to alleviate issues such as latency and jitter amongst others and improve packet delivery.

Evaluate the benefits of label-switching in MPLS and consider the characteristics of the technology and how it allows QoS in modern network technologies.

Word count approx. 2,400. References should be in the B&FC Harvard format and diagrams, tables and supplementary information supplied in appendices. Failure to do so will result in a loss of validity and reliability in your work which in turn will result in a loss of marks.

Task description This assignment requires you to consider the case scenario of Frank Wright. Frank Wright has undergone a right total knee replacement.

Applying your knowledge and understanding of the post-operative patient, you will write an academic essay applying the principles of surgery, consideration of patient co-morbidities and implementing nursing actions that identify, assess and prevent potential clinical issues.

Must be written in the format of an academic assignment and in third person.

You may use headings to differentiate the three parts.

The assignment has three parts –

Part A: Using the clinical reasoning cycle, devise a post-surgical plan of care for a patient who has undergone a total knee replacement

Parts B: Discuss the impact of co-morbidities and a general anaesthetic on post-operative recovery

Part C:  Discuss discharge planning for the patient following a total knee replacement

1. Provide an INTRODUCTION (approximately 150 words)

An introduction should provide clear scope about the direction of your assignment.

Part A  Utilising the case scenario and considering the pre and post- operative clinical data and academic literature devise a plan of care (approximately 600 words)

  1. This section will concentrate on the first 24 hours of post-surgical care.
  2. Analyze the case and formulate an appropriate prioritized plan of care for Frank within the defined 24 hour period.
  3. In the plan of care include:

I. Identify relevant assessment (e.g. vital signs, renal, respiratory, etc.)

I. Based on your assessment, propose three (3) potential patient clinical issues.

II. Based on your assessment and three (3) potential clinical issues, develop prioritized interventions (including monitoring). These interventions should include nurse initiated and collaborative interventions.

  1. The scope of your prioritized interventions may include both physical and psychosocial aspects of care.
  2. The care plan must involve justification of your prioritized interventions and supported with rationales derived from the literature.

Part B: Analyzing the case to identify potential clinical issues in relation to co-morbidities (400-500 words)

1.Discuss smoking, and the co-morbidity of hypertension, high cholesterol and obstructive sleep apnoea (OSA) in the context of having a general anaesthetic within the 24 hour postoperative period.

2.In your discussion, include the possible clinical issues related to the smoking and OSA that could arise in this 24 hour period and how Fred might deteriorate (You will need to reason explain the relevant pathophysiology).

3.Detail the nursing interventions the nurse would initiate to decrease risk of clinical deterioration and include your rationale for the nursing interventions. Justify your rationale with reference to the literature.

Part C: Discharge Plan (300 words)

1.Identify and briefly discuss discharge planning for Frank. Identify from the case the discharge planning that would need to be put in place for Frank. Keep this section brief.

Provide an conclusion (approximately 150 words)

Your conclusion succinctly summarizes the main points of your assignment but this section is not an opportunity to introduce new information.

Explain why a Poisson distribution is appropriate in this case and advise Eco-Fone if quality procedures have been met. Show all your workings.

/in /by

The company Eco-Fone Smartphones sells smartphones and accessories from two shops, one in Putney and one in Richmond. Eco-Fone does not currently sell laptops or tablets.

Business has fared well since it set up the shops in 2014. Indeed, it has seen a steady increase in net profits every year since start up. Recently it has noticed various trends among their customers.

One trend seems to be an increase in sales among older customers, some of whom are buying a smartphone for the first time. Another seems to be a possible significant difference in net takings from the two shops.

Accordingly, as a work placement from the University of Roehampton, you have been set a number of tasks, the results of which should be presented in report format for Eco-Fone (word length 2000, excluding graphs/figures/references) and written in English.

These tasks are detailed in the following pages and generally concern:

  • Summary information
  • Product information
  • Customer information
  • Financial Information
  • Recommendations for expansion

Your report should not be a simple list of tasks. Rather, it should read as a professional business report with an introduction, sections, summary, references and appendices, in Word format.

All tasks are worth ten marks each.

Task 1

(a)   You have been asked to write a brief overview of the mobile phone market in the UK. Specifically, Eco-Fone would like to know summary statistics with respect to work-related activities in the period 2016-17.

Prepare your one-paragraph overview based on information from Deloitte which can be found on page 19 and data in figure 6, page 20 at:

https://www.deloitte.co.uk/mobileuk2017/assets/img/download/global-mobile-consumer-survey-2017_uk-cut.pdf

and on Moodle.

Note that you should not copy verbatim the information contained in the Deloitte report.

(b) Based on the most recent data in Figure 6, include in your report your own mixed bar chart for 2016 (green) and 2017 (blue) for only the top FOUR activities. Include the data used in your appendix.

Task 2

Using an EXCEL spreadsheet, produce an appropriate line chart based on data contained in figure 3, page 13 of the Deloitte Report to represent the UK adult smartphone use in the period 2012-2017. Use your line chart to forecast similar use in 2018 and 2019. Show your workings.

Explain briefly why a linear forecast would not work well in this case.

Which forecast model would work well? Show the new model and use it to  forecast smartphone use in 2018 and 2019.

(You must show how you get the forecasts for 2018 and 2019 and include the data used to generate the charts in your appendix )

Task 3

Having gained a better understanding of the smartphone market, you decide to start analysing a perceived increase in smartphone sales by older customers based on a BBC news article available at:

https://www.bbc.co.uk/news/technology-41319684

Identify and summarize some of the features which make smartphones so popular with older customers.

Task 4

Currently, all of Eco-Fone’s operations are carried out at the two shops in the Borough of Richmond. The business has never operated across the border in Kingston but anecdotal evidence suggests that business is thriving. In order to initially answer Eco-Fone’s question “Should we expand our business to Kingston”, you have decided to use a ‘pros and cons method’ table (see figure T4). Complete the table and briefly summarize whether or not Eco Fone should expand its business to Kingston.

Figure T4.   A ‘pros and cons method’ table for expanding to Kingston.

Task 5

If Eco-Fone does decide to expand, extended operations will require improved facilities and, as it happens, highly-suitable new premises for retail use are available in central Kingston. The new building is available for lease or sale but Eco-Fone already owns (subject to repayment mortgage) the two Borough of Richmond shops and prefers to own rather than lease. The asking price for the new building is £400,000 but this might be negotiable closer to £350,000.

  1. a) Calculate the monthly cost of a 15-year repayment mortgage of £350,000, where interest is applied to the loan outstanding at the beginning of each year and the mortgage rate is 7% per annum. Show your Excel formula in your report Appendix.
  2. b) Represent an appropriate graphic containing any of the eight logos of well-known commercial mortgage lenders in the UK.

Task 6

Eco-Fone’s two retail shops offer discounted mobile phones and accessories. Both shops have been running for several months and Eco-Fone now wants to compare the net taking from both shops. A sample of 40 net daily takings from the first shop has a mean £100 and a standard deviation of £20. A sample of 40 net daily takings from the second shop has a mean of £90 and a standard deviation of £40.

Are the two shops’ net takings the same? Using the 5% level of significance, explain your findings.

Task 7

Each year Eco-Fone has regularly processed customer questionnaires in the form of hard-copy forms filled out both in the shops and as email attachments. The typical format of the questionnaire is shown in figure T7a.

Figure T7a.   Questionnaire

The latest results from these questionnaires are contained in the file Excel File Task 7 ( on Moodle) .

Use Excel to calculate average values for questions 1-6 and briefly summarise your findings in your report.

Task 8

The accounts department at Eco-Fone sends out about 10,000 invoices a month and has an average of two returned with an error per month? Quality assurance procedures require that the probability that more than three invoices will be returned in a given month should be less than fifteen per cent.

Explain why a Poisson distribution is appropriate in this case and advise Eco-Fone if quality procedures have been met. Show all your workings.

Task 9

Prepare a list of ten to fifteen references that you have used as sources for your report, all in Harvard format. Your list should include at least one text book, website, video, news article, journal and each one should be cited at least once in the body of your report.

Task 10

Based on all the data you have considered in Tasks 1-9, summarize in just one or two paragraphs your most important findings. Also, check the overall structure and presentation of your report (see the Brief in Moodle for more details).

Write 2-5 sentences summarizing the article/source and write 2-3 sentences on why this information is important and how you will potentially use it in your reflection paper.

/in /by

Describe a Personal Health issue that matters to you and that you learned about in this course. Use articles or pieces of information you found in your organization review or your annotated bibliography to justify and reference your statements. Try to answer the following questions:

What did you find most problematic about the personal health issue you are interested in?
Is there a possible solution to the issue? What recommendations can help solve the issue?
Should more people care about the issue?
Overall how do you feel about what you have learned about the topic of Personal Health?

Use APA formatting, Times New Roman font size 12, double-spaced with a minimum of 8 pages and maximum of 10 (this page count excludes title and references pages).

It should contain a title, abstract, discussion/conclusion, and references. Review the attachment ” APA Titles” in this folder to help you understand what each section should contain.
Review the grading rubric for the reflection paper on the syllabus. Use no less than 10 appropriate references, remember to use in-text citations using APA formatting and have all sources cited in the references list.

In general, write 2-5 sentences summarizing the article/source and write 2-3 sentences on why this information is important and how you will potentially use it in your reflection paper.

You need to do this for every single of the 10-15 sources you will use.

INTERNATIONAL TRADE ASSIGNMENT 1 SEMESTER 1, 2020

I. INTRODUCTION Assume that you are an economic consultant hired by an international organization/government to provide your expert advice on conditions pertaining to international trade in Argentina and El Salvador. Your analysis will consist of two separate reports (one for Assignment 1 and the other for Assignment 2). As an expert, your job is two-fold:

1. You are required to analyze any relevant issue using your technical skills. This involves utilizing your knowledge in international trade models as well as inspecting and interpreting data.

2. You need to communicate your results in an effective way. The purpose of this exercise is to assess your aptitudes in each domain. You will evaluate the trading conditions in these countries (Argentina and El Salvador) based on the scenarios detailed in each question in this Assignment. Your analysis will form the basis for a short report to the international organization/government body–summarizing your analysis and the associated rationale.
II. DATA SOURCE For your data analysis, you first need to obtain data from the World Bank (see the link below) and follow the steps described below. Notice that World Bank regularly updates its database; therefore it is crucial to obtain all data as soon as possible. The data range is from 1998 to 2014. You need to obtain the country-level data for Argentina and El Salvador on:

i. Imports of goods and services (in current US$)

ii. Exports of goods and services (in current US$)

iii. GDP (in current US$)

iv. GDP per capita (in current US$) v. GINI Index (World Bank estimate) from the World Bank’s World Development Indicators: (http://databank.worldbank.org/data/reports.aspx?source=world-development-indicators). [Note that if your browser (such as Chrome) does not open the web page, try a different browser (such as Internet Explorer)] DO NOT attach Excel files to the brief. The policy brief needs to be precise and short. Avoid unnecessary jargon. Your policy brief cannot exceed two pages.
International Trade Assignment 1, Semester 1, 2020 Page 2

III. REQUIRED TASKS Your tasks involve two dimensions. Firstly, you need to analyze the data (see Steps 1, 2 and 3 in the next section). Secondly, you need to perform a technical analysis by considering a hypothetical trading environment based on Ricardian model (see Step 4 in the next section).

Accordingly, you are required to:

 Provide information about how integrated these two countries (Argentina and El Salvador) are with the rest of the world. To do so, you need to look at their trade flows relative to their GDP and calculate openness.

 Provide a visual representation of your findings by plotting a graph (use line graph) that shows the change in openness for these countries over the period between 1998 and 2014 (including all years, i.e., 1998, 1999, …, 2014).

 Establish whether being integrated with the rest of the world helped these two countries by looking at the correlation between their openness and GDP per capita.

 Conjecture what would have happened if these countries were not open to trade with the rest of the world by evaluating a hypothetical scenario based on a simple Ricardian model.
IV. REQUIRED STEPS TO COMPLETE EACH TASK
DATA ANALYSIS For data analysis, you need to follow Steps 1, 2 and 3 given below. Step 1. Using trade flows in your data, calculate openness as a percentage for Argentina and El Salvador and present them for each year for both countries as a table. You need to explain your method, namely, how you calculated openness using trade flows (write down the formula). In addition, you need to state what other alternative ways you could have adopted to calculate openness other than using trade flows. Step 2. Using the calculations you did for openness in Step 1, plot openness (as a percentage) against time (1998-2014) for both countries (Argentina and El Salvador) in a single graph (as a chart type: you are required to use line graph). Put openness (as a percentage) on the vertical axis and time on the horizontal axis. Explain and compare briefly how openness changes for these countries over time. Make sure you limit your explanation to 200 words. Step 3. Explain in up to 200 words the relationship between openness and economic development by calculating the correlation coefficient between GDP per capita
International Trade Assignment 1, Semester 1, 2020 Page 3

(proxy for economic development) and openness for each of the two countries, respectively. [Here you have to use the CORREL command in Excel]. DO NOT ATTACH YOUR DATA.
TECHNICAL ANALYSIS For technical analysis, you need to follow Step 4. Step 4. In order to conjecture the circumstances in these two countries under autarky (when there is no trade), consider the following hypothetical scenario based on Ricardian model. Assume throughout that those two countries (Argentina and El Salvador) are the only two countries in the world, at least for purposes of trade. There are two goods: Hammers and Widgets. Consumers in both countries always spend half of their income on Hammers and half of their income on Widgets. The only factor of production is labour. Each Argentinian worker can produce 4 Hammers or 2 Widget per unit of time. Each El Salvadoran worker can produce 2 Hammers or 2 Widgets per unit of time. There are 50 workers in Argentina and 75 workers in El Salvador. You need to provide conditions in each country by stating:

a) Which country has an absolute advantage in Hammer? In Widget?

b) Which country has a comparative advantage in Hammer? In Widget?

c) Draw the production possibility frontier for each country and indicate slope (put Hammer on the vertical axis and Widget on the horizontal axis).

d) Find the autarky relative price of Widgets in both countries (i.e., the price of Widgets divided by the price of Hammers).

e) What is the optimal consumption and production for each country under autarky?
V. PRESENTATION OF RESULTS You need to provide a brief in order to effectively communicate your findings. In your brief, you must have the following ingredients:  Micro-credential: Include the URL link that verifies that you successfully completed the “Fact Check” micro-credential.  Headline: One possible example is: “A Simple Analysis of Openness for Argentina and El Salvador: Part I”  Data Analysis: In this section, you need to present your data analysis based on your findings in Steps 1, 2 and 3.  Technical Analysis: In this section, you need to communicate your technical results based on your findings in Step 4.

Computer Forensics and Cyber Crime: An Introduction by Britz

In an investigation being conducted by the state crime lab, senior investigators have called your company, AB Investigative Services, to provide advice concerning the interception of wire, electronic, and oral communications. The current individual suspected to be the source of the crime used a library computer to send and receive e-mails. The librarian walked up on the e-mail account while the suspect was away and found incriminating information in an open e-mail, which was reported to law enforcement.

Post your advice to the senior investigators addressing the following:
Define how the forensic investigator could interpret one aspect of one of the following statutes in relation to the given scenario using:
18 U.S.C. §§ 2510-22 Wire and Electronic Communications Interception and Interception of Oral Communications and,
18 U.S.C. §§ 3121-27 Pen Registers and Trap and Trace Devices
In your opinion, how can the interpretation be misconstrued or incorrectly interpreted by a forensic investigator?
Respond to other students’ posts, by addressing the following:
Defend how the First and Fourth Amendments apply or do not apply to the email in this case.
What other aspects could be misinterpreted based on current technologies?

c. Determine the risk set (this means the ids of the subjects) at time=10 and the corresponding term in the partial likelihood assuming that the data is coded Placebo=0 and Drug=1 and the parameter is β .

d. If the subject with id 10 was entered at time=11, that is there is delayed entry, how would this change the results of (c).

Question 2 The following data set (dialysis.csv) concerns the survival of patients after starting peritoneal dialysis. [Dialysis is a blood filtering treatment that replaces the function of the kidneys. Dialysis is started when an individuals kidneys stop working]. The interest is in modelling the time to death, but we will also do one analysis for transplant. This is not real data but is based on a real data set.

Variable Description id Patient Identify stat1 Status at end of followup (0=Dead, 1=Dialysis, 2=Transplant, 3=Lost to Followup) yrstotal Total years of followup gender Gender (1=Male,0=Female) diabetes Diabetes (1=Yes, 0=No) startyr Year started dialysis age Age starting dialysis
Analyses should be performed in Stata. a. Death i. Setup the data for survival analysis for death as the event, that is stat1=0 with all other outcomes considered censored.Show the command.Note:Think about what the value for censoring should be. ii. Using the covariate age,categorize into 3 equal,as possible,groups.Produce a Kaplan-Meier plot for each age group.Comment. iii. Determine the median survival with 95% CI for each age group.Why can’t the median survival be obtained for the lowest age group? iv. Determine the survival at 10 years with 95% CI for each age group. v. Perform a logrank test, and a test for trend for age group. Comment. vi. Fit a Cox model for age group and test for evidence of an effect of age group using a Wald test. vii.
