# Discussion: Psychology

Life Expectancy: What Does It Take to Live a Long Life?

According to the CDC, the current average life expectancy is 78.7 years old. Although there are some who live much longer, even up to 120 years. In your opinion, what factors contribute to those who live well beyond the average age? Consider lifelong healthcare regiments, attitudes, and behaviors. Are these factors in agreement with what psychologists find to be common in centenarians? Support your reasoning with information from the text and other course materials.

Socioemotional Selectivity Theory

Psychologists claim that those in late adulthood  are more selective about the company they keep because they are less willing to invest in relationships with emotional risk and they place a higher value on emotional satisfaction. Do you feel this a valuable way to approach social relationships? Why or why not? Could this approach be useful in other periods of development? If so, how? Support your reasoning with information from the text and other course materials.

# Maths, physics and statistics calculations

Starting in late 2007, the world’s advanced economies slumped into recession, often referred to as the Global Financial Crisis (GFC).  Canada joined the US, UK and much of Europe in watching real GDP fall for at least two quarters.

Part A.  Gathering, preparing and presenting data (3 points)

To collect data on the recent recession for Canada, carry out the following instructions:

1. Go to Statistics Canada’s website
2. Find National Gross Domestic Product, expenditure-based, Canada, quarterly (36-10-0104-01)
4. Select “Chained (2012) dollars”, “Seasonally adjusted at annual rates”, Retrieve data for the following Estimates
5. GDP at market prices
6. Household Final Consumption Expenditure (Consumption)
7. General Governments Final Consumption Expenditure PLUS General Governments Gross Fixed Capital Formation (Government). You will have to prepare the summed data yourself.  Adding these will provide an approximation that is comparable to US data.
8. Business Gross Fixed Capital Formation (Investment)
9. Exports of goods and services (Exports)
10. Imports of goods and services (Imports)
11. Place the data in a spreadsheet (Excel or similar)
12. Using formulas, construct an index of the data with 2007Q4 as the base time period (all series should equal 100 in 2007Q4). Your index should start in 2006Q1 and end in 2019Q4.
13. Repeat for: GDP, Consumption, Government, Investment, Exports, Imports
14. Plot a line chart for each index

To collect data on the recent recession for the USA, carry out the following instructions:

1. Go to the US Bureau of Economic Analysis Interactive Data site
2. Under Tools, Select “Interactive Data”, then “National Data”, then “GDP & Personal Income” then “Begin using…”
3. Under “Domestic Product and Income”, find the table for “Real Gross Domestic Product (A) (Q)” – table 1.1.6
4. Under Options, select quarterly data, starting in 2006Q1 and ending in 2020Q1
6. GDP at market prices
7. Personal Consumption Expenditures (Consumption)
8. Governments Consumption Expenditures and Gross Investment (Government)
9. Gross Private Domestic Investment (Investment)
10. Exports
11. Imports
12. Using formulas, construct an index of the data with 2007Q4 as the base time period (all series should equal 100 in 2007Q4). Your index should start in 2006Q1 and end in 2020Q1
13. Repeat for: GDP, Consumption, Government, Investment, Exports, Imports
14. Plot a line chart for each index

With these examples and the charts you constructed, you should have 12 charts.  All charts should be properly labelled (title, axis labels, scales).  Set your vertical axis scales and plot area to ensure a balance of comparability across charts against the ability to see variations in the data.

Insert the charts into a single document and then present your analysis in Part B.

Part B.  Analyzing the data (2 points)

Using the 12 charts you prepared in Part A, compare the 2008-09 recession in Canada and the US.  Which experienced the most severe recession?  Which had the fastest recovery?  What particular variables explain the differences in depth and recovery for each recession?  Explain your answer using the evidence from the charts.  You should research other published analysis of the recession of 2007-2008 (with citations) to help add context to your analysis.

The COVID-19 pandemic has initiated a large global recession.  Using research from published sources such as the International Monetary Fund, describe how large the COVID-19 recession is expected to be.  Based on your research, do you believe the COVID-19 recession will be more severe than the one experienced during the Global Financial Crisis?

Guidelines for submission

Your answers should be submitted on the Brightspace site – posted by the beginning of class on the due date.  Your answer should be submitted in ONE DOCUMENT (PDF, Google Docs or Microsoft Word).

There should be 12 charts.  Charts should be at least 3 inches tall by 5 inches wide.  Under each chart, you should include a source reference, for example:

Statistics Canada.  Table  36-10-0104-01   Gross domestic product, expenditure-based, Canada, quarterly (x 1,000,000), retrieved on May 9, 2019.

Part 4

Background

An information asset is a body of information that is defined and managed as a standalone, single unit that can be shared and exploited to the organization’s benefit. It is referred to as an asset because it has financial value to the organization. Enterprise- wide information assets that are common to large health care organizations include billing systems, EHR/EMR, master patient index, clinical automation systems, patient portals, personal health records, telemedicine, health information exchange (HIE), clinical applications (lab, pharmacy), etc.

The enterprise data warehouse (EDW) is a repository of high value data from different information assets and corporate systems/applications. The data contained in an EDW can be integrated for many strategic uses across the enterprise. Strategic objectives might include activities and initiatives designed to improve quality, safety, cost, productivity, etc.

To complete Part 4, conduct research into the topic of data warehousing in health care organizations and then answer the following:

1. List the benefits of an EDW to a health care organization.
2. Prepare a strategic objective and explain how it could be facilitated through use of a data warehouse.
3. Select two (2) information assets from the list above. Through a data warehouse, analyze and demonstrate how data from those two assets could be used to accomplish the identified strategic objective.

The structure of the dissertation should be

Very brief introduction

10 Sections each concentrating on one question

Very brief summary

References (if applicable, optional)

• Give a general introduction on the topics of Financial Risk Analysis skills learnt in this module. You need to choose one or two topic(s) for deeper discussion to include some additional literature reading, application examples and explain what you have gained the most by focusing on the topic(s).

• Carry out independent research on Altman’s Z-score as an investment value indicator — What is involved, how many types there are, how the scores are calculated, why it can be used as a value indicator. Use financial data provided by Yahoo Finance or Thomson Reuters on a few companies of your selection to cover all cases. Also, discuss the advantages and disadvantages of using such indicators for risk analysis purposes.

• There was a big housing bull market around the world over the last 30 years, you need to make some data backed investigation on the possible reasons for this. It is up to you to decide what data should be used in your study. You must involve quantified discussion, using some of the investigation methods such as regression analysis taught in this module. The historical UK house price data can be obtained from, for example,

• Design a retail business whose profit depends on a number of factors that can fluctuate randomly according some distributions and run a number of simulations on the model and plot the profit distribution histogram, and fit the histogram using different probability distributions as you see fit. Explain how you made your assumptions and the subsequent consequences on the outcome.

• Study the definition of hedge funds, look at the the investment strategies of hedge funds. Analyse the pros and cons of using hedge funds as an investment tool as you see them.

• Take out one of the strategies you discussed in 5) for detailed study. Must use asset/option prices from the real world in your illustration. The results must be in the form of price performance, in figures or graphs, using at least one statistical tools taught in the module.

• In the module we have described how to make investment decisions, in particular, we mentioned “Qualitative management screening: decide which projects, assets, initiatives or strategies are available, the list should meet management’s agenda. Most valuable insight is created at this stage”. Make a case study and explain the difficulties when we analysis financial risks with more than one factors.

• Study the definition of the following risk functions and how they are computed using MATLAB with concrete examples:
• VaR
• Expected Tail loss
• Omega
• Drawdown

Give your opinion on the pros and cons of using these risk measures.

• Carry out independent research on the coherence definition for risk functions, use concrete example to illustrate why coherence and incoherence are needed in different circumstances. Take a couple of risk functions to verify, using numerical examples, if they are coherent or incoherent.

• Select 20 different assets which you can download historical price data, explain the reason for selection. Construct a 20 variable VaR function, minimize it using MATLAB Optimization App. Choose sub-time intervals to compare the performance of thus formed portfolio against an equal-weight ETF using these 20 assets.

Remarks:

• There is no limit on the number of words but should avoid over/under explanation, figures and data presentation tables are more powerful tools in risk analysis.
• Programs in EXCEL, MATLAB can be used but must be displayed clearly.

# Business Intelligence & Data Mining

2000 words HIT353

Focus: in this project, is required to produce a detailed, in-depth document describing a proposed solution (Business Intelligence & Data Mining Solution) for an existing small-to-medium business (or virtual company) seeking an implementation of a BI solution  to fulfil their business objective(s).

Deliverables:

1. A final project report (30%)

– Can also be structured as an SRS document (Systems Requirements Specification).

Even though, you are not required to submit the final product (BI Solution) as fully functional and working product, it is important to describe the specifications, concepts (models) and technologies involved to implement the proposed system. You are not required to specify or describe in-depth the programming environment (language), however, general understanding of this aspect of the solution is accepted.

Below are further general guidelines and the options which you may consider for your Project. Choose one, and only one.

Selection of a Company (organisation):

Requirement: Select an existing small-to-medium business/organisation (or virtual company) seeking an implementation of a BI solution to fulfil their business objective(s), and report on the specifications of the Case and the proposed solution in a detailed document (report).

If you are looking for more directions, then I suggest the following approaches:

• You may wish to implement a solution for customer relationship management system in a small company (must be novel/original).
• Text mining / text analysis /data mining solution for a small business.
• Data warehousing and BI solution for a small business.
• You may wish to implement a solution for an invoicing system in a company (must be novel/original).
• You may want to proceed with a data driven approach that is to look at rawdata for inspiration. In the big data era, there are now many interesting opendata on the Web,

Is thereanything interesting you can do with the data? Some suggested examples are:

• Web-based crime visualisation application with crime details stored in DB;
• Web-based real estate project with real estate data stored in DB; clinicmanagement system project with patient and doctor etc… details in DB.

A final project report (30%); MUST include the following:

-Introduction

-Background

-Proposed solution overview:

• BI’s solution overview
• how is this solution relevant to the company?
• what and how will it achieve the business objectives
• originality, qualities
• constrains and assumptions

-Components (Data items, functional and system requirements)

-Models / Concepts / technologies

• Describe in detail themodels, concepts or technologies involved in the proposed solution.

– Implementation specifications of the proposed solution

• General description of how the solution will be implemented in the existing (or virtual) company/organisation (*hint: the company might have multiple existing systems and software in use). Must show a clear understanding of the complexities and challenges that might occur and how to overcome it (apply knowledge learnt from previous case studies. *hint tutorial case studies Qs&As)

-Reference list

IMPORTANT

This is not a task which can be completed simply by gathering information from the internet. Original thinking is required, demonstrating sound reasoning and rational assumptions to support your proposed solution. Inspirations from other case studies are encouraged, however, originality is a requirement.

Attention is drawn to the University’s policy on plagiarism. Note also that marks will not be awarded for information taken directly (copy/paste) from the internet, even if it is referenced.

The report must be set out as a formal technical report, in word .doc or .pdf file format, and it will be marked as such. As an indication, the length requirement for this report is approximately of 3000 words; however, marks will be awarded for quality, not quantity.

Format:

Use font: Arial or times new roman; size: 12; double spacing; CDU Harvard referencing, in-text citation.

-The end –

The assignment for Leadership and Management is an individual written report outlining the key ideas that should be considered in understanding Servant Leadership. This includes explaining what is involved in being an effective servant leader, and some researching on the effectiveness of servant leadership and how servant leadership varies across different cultures.

As a way to help you structure this, these are the three main specific questions for you to answer:

• Is Servant Leadership truly an effective leadership style/theory and what are the flaws of this leadership style?
• How does Servant Leadership vary across different cultures?

You must provide answers to all of the questions and must fit within the word count. You must clearly inform the reader about critical considerations in developing and practicing good servant leadership.

The written report significantly focuses on the idea of servant leadership. You need to present your answers and arguments of the questions to be fully supported by evidence from appropriate leadership academic references (leadership journal articles, leadership studies, real-life servant leadership examples) that have come from a reliable and trustworthy source.

Charts, diagrams and figures may all be used wherever appropriate to the points being made. You are not required to use them, but if you do then you are expected to reference them correctly.

Word Count:

2000 words (not including title page, contents page and reference list)

You must provide examples of Servant Leadership models and examples of real-life servant leaders and incorporate these examples into the written report.

*Within the other file attached, I have included the topic/aspect of Servant Leadership that has been covered. It is CRUCIAL for you to read this topic as well as carry out research in answering the questions and writing the written report. The other file attached will give you an insight of understanding Servant Leadership and will help you with this written report.

*It is important to not only use but further develop the information in the other file in relevance to the questions with research.

*IMPORTANT:

It is highly important to start the written report EARLY, in order to avoid doing the written report assignment in last minute and gives more time for editing and proofreading.
