I need at least 1 page, double spaced, 12 pt., Times New Roman, APA citations, APA reference page, general paper over the lab topic you plan to cover for your scientific lab report. Tell me why you picked the topic, a little background about your topic, and find at least 1 similar study to your lab experiment (read your lab manual directions for that particular lab that you pick) you found by doing RESEARCH at Library/Internet (scholarly! NO student experiments) and write about the scientist(s) main results. Make sure the study you found is set up as a scientific paper (ie. abstract, introduction, methods, results, discussion, and references). Read over it carefully to understand the layout of a scientific paper because YOU will be writing one for PART II. Please make a photocopy or print off the scientific study you found that relates to your topic and staple it to your paper (if it is lengthy just print a few pages). This can be 1 of your references when you write your actual scientific paper. 


Research paper – 3 Pages, APA 6th edition MUST, Please find the question below. 2 Scholarly reference MUST


Industry experts believe blockchain is a technology that has the potential to affect the business of most IT professionals in the next five years. Pick an industry you feel will be most affected by blockchain and how blockchain may be used in that industry. As an IT manager, how would you embrace blockchain? For instance, how would training occur for your team, what strategies might you use, what security methods may you recommend be used?

Your paper should meet the following requirements: Be approximately 2-3 pages in length, not including the required cover page and reference page. Follow APA 6th Edition guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.

Assignment 5: Tour Operator Agency Database
Due Week 6 and worth 90 points

The Strayer Oracle Server may be used to test and compile the SQL Queries developed for this assignment. Your instructor will provide you with login credentials to a Strayer University maintained Oracle server.

A multinational tour operator agency has gained new business growth in the North American market through the use of social media. Its operation has expanded by 50% within six months and the agency requires an enhanced data management strategy to sustain their business operations. Their existing data repository for its reservation processing system is limited in business intelligence and reporting functionalities. The tour operator seeks a database management specialist to assist them in leveraging their data sources to enable them to forecast and project tour sales appropriately.

Imagine that you have been hired to fulfill their need of enhancing the data repository for their current reservation processing system. Upon reviewing the system, you find that the data structure holds redundant data and that this structure lacks normalization. The database has the following characteristics: A table that stores all the salespersons. The table holds their employee id, first name, last name and “Tours sold” field. The “Tours sold” field is updated manually. A table that stores tour customer data and tours sold. The table holds customer name, address, city, state, zip code, tour(s) selected, number of persons in tour, and total amount paid. The current structure will show the customer more than once, if the customer books multiple tours. A tour table that is used as a tour rate sheet which holds the tours offered and the cost per person. Tour rates vary every three (3) months depending on the tourist season.

Write a three to four (3-4) page paper in which you propose an enhanced database management strategy. Your proposal should include the following: Design a data model that will conform to the following criteria: Propose an efficient data structure that may hold the tour operator’s data using a normalization process. Describe each step of the process that will enable you to have a 2nd Normal Form data structure. Create naming conventions for each entity and attributes. Conclude your data model design with an Entity Relationship Model (ERM) that will visually represent the relationships between the tables. You may make use of graphical tools with which you are familiar. Note: The graphically depicted solution is not included in the required page length. Construct a query that can be used on a report for determining how many days the customer’s invoice will require payment if total amount due is within 45 days. Provide a copy of your working code as part of the paper. Using the salesperson table described in the summary above, complete the following: Construct a trigger that will increase the field that holds the total number of tours sold per salesperson by an increment of one (1). Create a query that can produce results that show the quantity of customers each salesperson has sold tours to.  Support the reasoning behind using stored procedures within the database as an optimization process for the database transactions.

Your assignment must follow these formatting requirements: Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions. Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length. Include charts or diagrams created in any chart or drawing tool with which you are familiar. The completed diagrams / charts must be imported into the Word document before the paper is submitted.

The specific course learning outcomes associated with this assignment are: Explain the fundamentals of how data is physically stored and accessed. Compose conceptual data modeling techniques that capture information requirements. Design a relational database so that it is at least in 3NF. Prepare database design documents using the data definition, data manipulation, and data control language components of the SQL language. Use technology and information resources to research issues in the strategic implications and management of database systems. Write clearly and concisely about topics related to the strategic planning for database systems using proper writing mechanics and technical style conventions.

Introduction to art


Download book:

Looking at art objects throughout history you will notice  they all share  a few basic elements. You may see immediately see a few characteristics how many related characteristics do you see? (based on reading and research analyze the work of art) perspective, line, shape, mass value, color and texture.

(Line foe example may be curved/triangular/serpentine/jagged invisible directive line)

In at-least TWO PAGES discuss in detail  how  THE Elements and Principles  were used in the attached  art work. YOU MUST DISCUSS AT LEAST 5 ELEMENTS AND PRINCIPLES IN THE PAINTING. Most of all discuss how Unity, Emphasis  and Perspective are achieved. Consider what is emphasized/ WHY and HOW.  (You must be very detail) Add the image to your paper so I can follow your analysis as you discuss the image. Do not forget to place an appropriate caption under  your image. Do not forget to list sources used. This class requires at-least 3

Using a Web browser, perform some research on a newer malware variant that has been reported by a major malware containment vendor. Using a search engine, go to the vendor’s Web site; this could be Symantec, McAfee, or any of their competitors. Visit one malware prevention software vendor. Search for the newest malware variants and pick one. Note its name and try

to understand how it works. Now look for information about that same malware from at least one other vendor. Were you able to see this malware at both vendors? If so, are there any differences in how they are reported between the two vendors?


Need two pages of work around (500 or more words). 

APA format with appropriate references.
