March 1st, 2020 Graduate, Quantitative Design and Analysis Comments Off on Correlation

Correlation

Part 1: Interpreting Correlations
A meta-analysis (Anderson & Bushman, 2001) reported that the average correlation between time spent playing video games (X) and engaging in aggressive behavior (Y) in a set of 21 well-controlled experimental studies was r+ = .19. This correlation was judged to be statistically significant. In your own words, what can you say about the nature of the relationship? Write a one-page response to this question.

Part 2: Correlations
You will use the following resources for this assessment. They are linked in the Resources.

Complete this part of the assessment using the DAA Template.
Read the SPSS Data Analysis Report Guidelines for a more complete understanding of the DAA Template and how to format and organize your assessment.
Refer to IBM SPSS Step-By-Step Instructions: Correlations for additional information on using SPSS for this assessment.
If necessary, review the Copy/Export Output Instructions to refresh your memory on how to perform these tasks. As with your previous two assessments, your submission should be narrative with supporting statistical output (table and graphs) integrated into the narrative in the appropriate place (not all at the end of the document).
You will analyze the following variables in the grades.sav data set:

gender.
gpa.
total.
final.
Step 1: Write Section 1 of the DAA
Provide a context of the grades.sav data set. Include a definition of the specified variables and corresponding scales of measurement. Indicate the type of correlation for each X, Y pair (for example, Pearson’s r, Spearman’s r, point-biserial r, et cetera). Specify the sample size of the data set.

Step 2: Write Section 2 of the DAA
Test the assumptions of correlation for gpa and final. Paste the SPSS histogram output for each variable and discuss your visual interpretations. Paste SPSS descriptives output showing skewness and kurtosis values and interpret them. Paste SPSS scatter plot output with gpa set to the horizontal axis and final set to the vertical axis. Conduct a visual inspection of the scatter plot to analyze other assumptions of correlation. Summarize whether or not the assumptions of correlation are met.

Step 3: Write Section 3 of the DAA
Specify a research question related to gpa and final. Articulate the null hypothesis and alternative hypothesis. Specify your alpha level.

Step 4: Write Section 4 of the DAA
Paste the SPSS output of the intercorrelation matrix for all specified variables.

First, report the lowest magnitude correlation in the intercorrelation matrix, including degrees of freedom, correlation coefficient, p value, and effect size. Interpret the effect size. Specify whether or not to reject the null hypothesis for this correlation.
Second, report the highest magnitude correlation in the intercorrelation matrix, including degrees of freedom, correlation coefficient, p value, and effect size. Interpret the effect size. Specify whether or not to reject the null hypothesis for this correlation.
Third, report the correlation between gpa and final, including degrees of freedom, correlation coefficient, p value, and effect size. Interpret the effect size. Analyze the correlation in terms of the null hypothesis.
Step 5: Write Section 5 of the DAA
Discuss the implications of this correlation as it relates to the research question. Conclude with an analysis of the strengths and limitations of correlational analysis.

February 27th, 2020 Graduate, Not set Comments Off on Glycolysis, Gluconeogenesis, and the Role of Aldolase Gene Expression: Presentation

Glycolysis, Gluconeogenesis, and the Role of Aldolase Gene Expression: Presentation

Regulation of glycolysis and gluconeogenesis is a critical concept in biochemistry and often difficult for students to learn. This assignment allows the student to formulate a presentation on the topic and link this to the regulation of aldolase expression in various tissues of the body.

Give a 25-minute lesson teaching with a PowerPoint presentation. Each of the following topics should be covered (review the rubric for context):

-An overview of the glycolysis and gluconeogenesis pathways
-How aldolase is involved in both glycolysis and gluconeogenesis
-The different isoforms of aldolase and their different expression patterns
-An examination of how Aldolase B expression can be regulated by transcription factors HNF-1, HNF-3, C/EPB, and DBP

The lesson presentation should include a title and reference slide and have between 10-15 content slides. At least four references should be cited (only one can be the textbook).

February 27th, 2020 Computer science and IT assignments, Graduate Comments Off on Network Defense System

Network Defense System

It is essential to have a basic understanding of network defense topologies in order to properly comprehend the defensive strategies deployed by companies to protect their information assets.
Use the Cisco Packet Tracer application to create a network diagram that makes use of the following devices listed below, which belong to Company X. The diagram should illustrate your knowledge of network defense by placing network assets in their proper location, so as to ensure their protection. Include, within the diagram, any small office/home office (SOHO) solutions that will be used to protect either the infrastructure or end-user devices.
Within the diagram make sure to include at a minimum:
10 mobile devices (phones/laptops/tablets)
Five desktop/stationary computers
Two servers (file/email)
One printer
One router/firewall
One WAN/gateway connection
One switch
One corresponding backup/replication asset for disaster recovery (local or remote storage/server)
Note: Any IP addresses used should be labeled next to the corresponding device.
Then, create a report outlining the abilities of the network topology in reference to securing network devices and other information assets used by Company X. Make sure to address the following within the report:
A detailed explanation of the topology design addressing the “why” and “how” of the topology defenses solution and design, specifically threat models, motivations (such as insider threat), and ideologies
Network defense solution list (i.e., software/hardware used to protect information assets)
Encryption policies used by the network and end-users
Disaster plan recovery, including restoration plans
When completing the report for this assignment, refer to the “Report Template.”
APA style is not required, but solid academic writing is expected.
This assignment uses a basic scoring guide, provided by your instructor. Please review the scoring guide prior to beginning the assignment to become familiar with the expectations for successful completion.
You are not required to submit this assignment to LopeWrite.

February 24th, 2020 Data analytic, Programming, Graduate Comments Off on Semantic Caching Demo on SparkSQL and HDFS

Semantic Caching Demo on SparkSQL and HDFS

Overview: A caching system management used in SparkSQL/Apache Spark and HDFS

Requirements: SparkSQL, ApacheSpark, HDFS, Data caching algorithm and English skills.

Motivation: We are now using the HDFS to store and manage the data. And we do also the data analytics using SparkSQL in Apache Spark.

Normally, the Application Driver of Apache Spark will load the distributed data in HDFS into memory and do the processing. Finally, Spark will return the results to the HDFS. Sometime, the results we got from previous queries could be used again once or more time by next queries. Then, we want to cache these result in our memory long enough by using a mechanism of caching, it called semantic caching.

What we want is: an implementation of semantic caching program in Apache Spark. The program should be done by Scala/Java language but Scala is preferable.

February 22nd, 2020 Graduate, Websites, web programming Comments Off on Browser Extension

Browser Extension

I need a simple browser extension for chrome. It must do the following things:

1) have a user sign-in with username and password and verify user info against a SQL database. keep the user signed in even after closing the browser. Have a logout button once signed in.

2) when the extension detects you are on a specific site have it overwrite & autofill info into a sign-in form using database information only if the user hasn’t exceeded the maximum number of active sessions allowed by the database.

3) display users active sessions for that site in the extension.

4) once user signs into site track users active sessions on the site and report back to the SQL database and close sessions once the user leaves the site or clicks to sign out on the site

5) when a user deletes the extension open up a specific page
