2.1. Question 1 (from unit1 video transcripts and Sony case study)

Unit 1 focused on various leadership roles and their respective responsibilities in implementing an effective cybersecurity governance plan. Consider the leadership roles in Sony and their responsibilities in implementing the organization’s cybersecurity strategy:

  • Drawing on your learnings from this module, explain the organization’s governing structure, and its approach to cybersecurity (as detailed in its policies and, where possible, observed in practice). If you are focusing on Sony, you may extrapolate the formal roles from the data available (in the case study and from your own research) and contrast this with what was observed.
  • Based on your substantiation above, recommend changes that should be implemented and, if applicable, propose a new cybersecurity leadership plan that addresses its shortcomings.

(Approx. 300 words)

Start writing here:

2.2. Question 2 (from unit 2 notes and Sony case study)

Unit 2 of this module described the management processes organizations should consider when developing a cybersecurity governance plan. Identify the steps Sony is taking to implement the management processes discussed in the Unit 2 notes, and address the following:

  • Evaluate why the management processes utilized by Sony were insufficient to ensure good cybersecurity governance; and
  • Based on your substantiation above, recommend management processes that would have addressed Sony’s shortcomings in implementing a cybersecurity governance plan and should be adhered to going forward.

(Approx. 250 words)

Start writing here:

 2.3. Question 3 (from unit 3 notes and Sony case study)

Unit 3 focuses on the importance of keeping an organization’s cybersecurity awareness updated. To do so, the notes described the types of security awareness training that are available and the topics that should ideally be included in training programs. In your answer, address the following:

  • If relevant, identify any cybersecurity awareness programs or practices utilized by Sony, and evaluate whether they sufficiently cover the recommended topics mentioned in the Unit 3 notes.
  • Based on your substantiation above, provide an outline of a cybersecurity awareness program you would suggest for Sony.

Your outline of the training program should cover the following four aspects:

  1. The type of security awareness training (classroom or online);
  2. The topics included in the training program;
  3. The target audience; and
  4. The roles and responsibilities of those responsible for executing the training program.

Each aspect should be accompanied by reasons for your choices based on the organization’s context and needs.

Nudging healthy and sustainable food choices: three randomized controlled field experimentsusing a vegetarian lunch-default as a normative signal. Journal of Public Health.1The first step will be tocarefully read the paper. All main analysis in this paper uses methodology that has been covered in yourcoursework.Question 1.1:Summarize the article’s main finding and highlight the contribution you deem most impor-tant and most surprising.Question 1.2:Compare any two experiments of the paper in your own words: who are the treated units,what is the response variable and what is the treatment? Discuss the role of randomization and thedifferences in the treatment choices. Why did the authors rely on multiple experiments?Question 1.3:Discussconsiderationsofinternalandexternalvaliditythroughoutthewholestudy(allthreeexperiments), highlighting potential trade-offs in general and how they relate to the studies carried out.Question 1.4:The paper presents group differences in a plot and discusses these in text. Pick one compar-ison and carry out step-by-step the hypothesis testing (with the𝛼value of your choice) for a differencein proportion.Question 1.5:The paper discusses some differences between men and women. Present a brief outline ofa study that you would design to get a more detailed view of these differences and the potential reasonsbehind them.Question 2: Personality traits and political attitudesYouwillbeworkingwithpartsofthedatafromVitriol, J.A., E.G.Larsen&S.G.Ludeke. 2020. JustasWEIRD?Personality Traits and Political Attitudes Among Immigrant Minorities. Journal of Research in Personality85:2Reading the paper can help you with giving better answers, however, the questions and tasks can becarried out without that.You will have at your disposal a subset of some questions used in the paper (Immigrant panel (LISS-Ipanel) in the Netherlands) in thetraits.Rdatafile (ortraits.csvfile). Not all respondents or itemsare included in the data, thus your results will not be comparable to the ones in the paper. This is not areproduction exercise. The dataset is described below (see next page).Before starting your work, you will have to take two decisions:1.from the five Personality Trait variables (see table and/or paper), select one as your trait of coreinterest. We will refer to this as “main predictor” in the tasks.2.fromIdeology,PoliticalTrust,andSatisfactionwithDemocracyselectoneasyourresponse/dependentvariable for the regression tasks. We will refer to this as “response/dependent” variable in thetasks.You do not have to give a reason why you chose what you chose, simply state your choice. You shouldanswer the following data analysis and interpretation related questions/tasks below. Please rememberthe coding of the response/dependent variables.1The article is also made available on Canvas.2The article is also made available on Canvas. When you load the data, you should have 815 rows and 12 columns.2

Carry out a hypothesis test step-by-step with your own calculations (you can use R forthese) and also present the formulas you used. Use an𝛼level of 0.05. Do your conclusions change if youuse an𝛼level of 0.1? Compare your results with the output from anRfunction that you find appropriateto answer this question. Please use two-tailed tests.Question 2.2:Is the average level of agreeableness statistically significantly different between Dutch andnon-Dutch respondents? Present the hypothesis test either by carrying it out step-by-step or by relyingon a built in function for mean differences. Use an𝛼level of 0.05. Do your conclusions change if you usean𝛼level of 0.1? Please use two-tailed tests.Question 2.3:Summarize your main predictor (chosen above) variable using the appropriate measuresof central tendency and spread. Create a univariate summary plot and interpret what it displays. Cre-ate a plot that summarizes the bivariate relationship between the response/dependent variable and thechosen main predictor. Summarize the relationship through a correlation coefficient.Question 2.4:For your response/dependent variable, calculate the standard error of the mean, constructa 95% confidence interval for the mean and interpret these two uncertainty measures (standard error andconfidence interval). Do this relying on your own calculations (you can use R for these) and also presentthe formulas you used.Question 2.5:Run a linear regression where your chosen response/dependent variable is a function ofall five personality traits and the dutch, fg, and nw variables. Interpret the model results in substantiveterms and discuss measures of uncertainty and hypothesis test for the coefficients of interest.Question 2.6:Extend the previous model in a way that can answer if there are heterogeneous effects onyour response/dependent variable regarding your chosen main predictor and non-Western background.Report the model results in a table format and interpret the terms of interest and what this means foryour substantive conclusions. It is recommended, but not mandatory to offer a visual display of therelationship.For most of this question you have to carry out the analysis inR. This code has to be included as Ap-pendix and should produce the results featuring in your report. If something is reported in the text (alsofigures/tables used), it has to be included in the code.3

Question 3: Polls and election results in 2015 and 2019We have looked at how well polls or betting markets predict electoral outcomes in the US. In thepoll-dk-comp.Rdata(orpoll-dk-comp.csv) file you have Danish political party support polling numbers.This dataset covers two parties, three polling companies, and two pre-election periods (2015 and 2019).The dataset is described below.3Variable name DescriptionidID for each pollpollingfirmPolling firm conducting the pollpoll_dateDate of data collection (character)nSample sizeparty_oSupport forDansk Folkeparti(in %)party_vSupport forVenstre(in %)party_o_res_15Election result forDansk Folkeparti(in %), 2015party_v_res_15Election result forVenstre(in %), 2015party_o_res_19Election result forDansk Folkeparti(in %), 2019party_v_res_19Election result forVenstre(in %), 2019Using the concepts and metrics discussed in the course, analyzing solely the data at hand and relyingon your own analysis, answer the following questions. Please always describe how did you reach yourconclusion and what data/metric supports the conclusion. Depending on the measures you consider orangle you take in your analysis, there might be different answers to these questions. This is normal, butthis is also why it is essential to describe why you chose those measures, how you made the comparisonsand how they substantiate your conclusion.Question 3.1:In which pre-election did YouGov perform better, 2015 or 2019? How about Voxmeter?Question 3.2:Relying on polls from both companies carried out in the last week before the elections (both2015 and 2019), which party’s electoral result was better predicted?Question 3.3:Relying on all polls, how did the quality of prediction change as we got closer to the 2015election date? Please use at least one visualization to substantiate your conclusions. How was this dif-ferent in 2019? Discuss the potential differences or similarities.Question 3.4Does the poll’s sample size matter for the quality of predictions, and if so, are there between-party differences in how important these are? Discuss the potential role of the timing of polls as well,relating your answer to point 3.3.For most of this question you have to carry out the analysis inR. This code has to be included as Ap-pendix and should produce the results featuring in your report. If something is reported in the text (alsofigures/tables used), it has to be included in the code.3When you load the data, you should have 56 rows and 10 columns.4

Create your own Shoe class that holds data on: product ID, brand, name, model (Men, Women, Unisex or Children), shoetype (running, walking, everyday, etc.), shoe size, price and quantity in stock

/in /by

This task should render in an executable program in Java. In two java files. For grade G: Make an executable program according to the specification below where a business can manage a stock of shoes. Create your own Shoe class that holds data on: product ID, brand, name, model (Men, Women, Unisex or Children), shoetype (running, walking, everyday, etc.), shoe size, price and quantity in stock. Make a class using the main method where objects are created by the Shoe class. (NOTE: Do not use ArrayList). When the program is executed, a list of the choices a user can make is displayed in the Eclipse console and the user should be able to choose what the program should perform (see a-j below) and the program should not be shut down until the user chooses to quit. The array of shoes should have room for 20 shoes. When the program is started, the 3 shoes shown below should be automatically added to the array (eg retrieved from a text file). First: Product ID: H037 Brand: Nike Name: Lunarglide 8 Model: Mr. Shotype: Running Shoe size: 42 Price: 1100 Quantity in stock: 5 Second: Product ID: D001 Brand: Ecco Name: Light IV Model: Dam Shoetype: Walking Shoe size: 36 Price: 690 Quantity in stock: 12 Third: Product ID: U020 Brand: Meindl Name: X-SO Model: Unisex Shoetype: Walking Shoe size: 39 Price: 1499 Quantity in stock: 3

The user should be able to choose to do the following:
a). Adding shoes to an array of shoe items, you should also check to make sure it doesn’t already exist a shoe entered with the same product ID. If there is already a shoe with the product ID, it should do not add it to your collection and a message will be displayed to users. For example: ”A shoe with product ID H037 is already in your collection”

b)Change / update price and quantity in stock of a shoe based on product_id c) Remove shoe based on product_id.

d) View all shoes in the array and all data about each shoe.

e) Calculate the value of a searched type in the warehouse (the calculation should be done based on price and number, how many you have in stock of that particular type of eg. running, walking, winter etc.)

f) Search and view all the data for the shoes that are in the array of the searched shoe brand.

g) Show which shoe brands are available from a searched shoe model (women, men, unisex or children).

h) Search for a shoe type and show how many copies you have in the stock of the searched shoe type.

i) Show which shoes are in stock based on product_id and which shoes are finished (ie whose number is = 0)

“Haverbrook investment limited, L.L.L.p. (HIG)” is an organization that mainly majors in the provision of financial services, and it possesses a total of 9.7 million dollars in revenue. The organization whose roots can be traced to Largo, Maryland, presently has approximately 350 subsidiaries all over the united states and provides jobs to over 8,738 and offers its services to nearly 8.5 million clients. To ensure that the company resources and the client’s information is secure the organization, senior manager Beth Haverbrook, employed “Centralia Security Lab (CSL)” to complete a penetration assessment into the company IT systems and determine the level of the company effectiveness in protecting the company information and client’s data.

The objective of the rule of assignation is to set the procedures or the principles for both the company as well as those of the CSL penetration personnel, understand the needs of the clients, layout the project prospects and arrive at a conscious through an obligatory contract. Interviews were held by both the CSL and HIG to gather the client data and further consultations to create the “ROE for the penetration testing process.” Consequently, they came up with the scope, the handling of data as well as the requirement for the project
