Machine learning is an application of artificial intelligence (AI) that provides systems the ability to automatically learn and improve from experience without being explicitly programmed. Machine learning focuses on the development of computer programs that can access data and use it learn for themselves.

The process of learning begins with observations or data, such as examples, direct experience, or instruction, in order to look for patterns in data and make better decisions in the future based on the examples that we provide. The primary aim is to allow the computers learn automatically without human intervention or assistance and adjust actions accordingly.

What is machine learning with example?
For example, medical diagnosis, image processing, prediction, classification, learning association, regression etc. The intelligent systems built on machine learning algorithms have the capability to learn from past experience or historical data.

Advantages and disadvantages of Executory arbitration

This is an assignment that discusses the advantages and disadvantages of Executory arbitration. The paper also discusses the legality of executory arbitration.

The advantages and disadvantages of Executory arbitration

S‌‌‍‌‌‍‍‍‌‍‍‌‍‍‍‌‌‌‍uppose that you are the HR manager for a company. Following a string of expensive law suits with former employees, your boss asks you to prepare a memo articulating whether or not your company should add a new policy in all employment agreements and employee handbooks which makes arbitration mandatory for any disputes arising out of employment with your company. Your boss is interested in reducing both the cost and public visibility of employment disputes. However, she is also concerned about any legal problems with executory arbitration, including precedents. This is as well as any negative PR that might come out of such a move.

Draft said memo thoroughly discussing the options and their implications. Be sure to address, at minimum, the following:

1. What are the advantages and disadvantages of arbitration as compared with the status quo of litigation? Also, are there any other alternatives worth considering?

2. Is executory arbitration legal? Are there any circumstances under which such an agreement might not be enforceable?

3. Even if it is legal, how are such agreements viewed generally? Are they perceived as fair among the general public? Are there any potential repercussions in that respect worth considering?

4. What are the implications concerning arbitration in terms of precedent and privacy? Do arbitration decisions create legal precedent? If so, can employees disclose information discussed in arbitration hearings to other parties without the company’s consent, such that it may be used in subsequent disputes?

Submission Instructions:

This assignment should at a minimum contain 1,000 words of content (there are four parts, so this is ~250 words each). Word count does not include headings, cover pages, references, or question text (if you choose to include it in your paper); I am looking for 1,000 words of substance.

Your paper should be in APA format including a properly formatted cover page (abstracts are optional) and a reference page with at least three (3) NEW references (here means references that you have not already used in previous assignments in this course). Providing additional references to your assignments demonstrates your desire to conduct additional research on the topic area, and can improve your research skills.

Distributive justice variance moderation and mediation

This essay entails a research paper on the Variance moderation and mediation and its reflection to the extent of distributive justice. Variance moderation and mediation is a term used to maintain the level of court delivery in the governance and offering of equality.

Variance moderation and mediation extent of distributive justice

Firstly, explain variance partitioning, hierarchical regression, moderation and mediation. What is the meaning of each one of these techniques and what kinds of research questions can be appropriately addressed by each technique?

Secondly, the data set, SATPJ.sav contains 6 variables: REC, PAY, DJ, PJ, ANG, AND SAT.  REC – recognition or praise from your supervisor. PAY – pay. PJ – procedural justice, or the extent to which your supervisor followed fair rules and procedures for determining your rewards. DJ – distributive justice, or the extent to which the rewards you received from your job were fair

Also, from model A and Model B present two different hypotheses about the relationships between the variables in our data set for the week. For model A, identify which variables are endogenous and exogenous. For both models, identify the variance in satisfaction explained by the independent variables, partition the variance explained into its components. Calculate the unique contributions of the variables. Interpret your analyses and draw conclusions about the nature of these relationships.

Furthermore, find three articles in your research area of interest and assess the extent to which they conform to the practices. Becker recommends regarding the use of control variables.  Do you think Becker’s recommendations are reasonable or ill-considered?  Would you modify any of his recommendations?  Bring your example articles to class for our general discussion.

Eventually, the effect of having goals on the job on an employee’s proactivity might depend on the level of an employee’s motivation. The relationship between goals and proactivity might be stronger when motivation is high rather than when it is low.

Lastly, on sector one test this theory by regressing proactivity on to motivation and goal, and test for the interaction of these two variables.

Results analysis

Thirdly, compare analyses using centered variables with analyses using uncentered variables.  Explain the differences in estimated coefficients between these two approaches.  For both the results from the uncentered and centered equations, graph your results, and compute the simple slopes at low and high values of motivation. Statistically and substantively interpret your results.
Lastly, Graph your results, and compute the simple slopes for each gender.  Statistically and substantively interpret your results.

Information Technology vendor hardware and software issues

This essay entails a paper on the Information Technology vendor and solutions to malfunctions on hardware and software issues. Information Technology vendor is any person or firm that offers support to another firm on data management matters.

Information Technology vendor hardware and software issues

Beginning about the same time, a new IT vendor came in to do an upgrade on the computers and software used in the department. However, some of the new software was not available in time for the upgrade and the old software was not fully cleared from the department computers.

The new IT vendor still has problems completing the upgrades, and virtually all department employees spend some of their shifts tracking down old software applications and clearing them from the department’s computers. Two of the employees who previously worked in the department are no longer there. One was injured in a car accident approximately four and a half months ago and has not yet returned to work.

The other employee left the company three months ago to move to another state. These particular employees had not participated in the vendor training that took place. However, they did spend quite a bit of time managing the department’s IT hardware and software issues. While other employees focused on taking care of the rest of the department’s activities.  In order to satisfy your manager’s directions, you will need to complete the following steps:

Additional information

Create 3 separate line graphs – one for each of the data sets (3) that your manager provided to you – Sales, % of GM plan, and % of Employee Availability over Last Year to Date. You will need to convert the Sales data into % of Plan in order to chart the data). Insert trend lines in each of your individual line graphs. Once you have completed your individual line graphs, prepare another graph that combines all of the data from the three individual graphs.

Again, insert trend lines for each data series. Use the information in your completed charts to identify trends, determine possible causes using one of the root-cause analysis techniques. Make predictions based on qualitative (interviews with employees) and quantitative (charts and trend lines) information.

Based on the results of your critical analysis of the above information. Identify opportunities for improvement in the department, and outline a six-month action plan for implementing those improvements.

More details on the assignment;

A food system includes all processes and infrastructure involved in feeding a population: growing, harvesting, processing, packaging, transporting, marketing, consumption, and disposal of food and food-related items.

What is global food production?
A common perception is that global food supply is currently sufficient to feed the world’s population, with timely distribution required to avoid hunger (World Hunger Organisation, 2016), but that food production must increase dramatically in the next decades (Food and Agriculture Organisation of the United Nations.
Why is the food system important?
As countries around the world work towards achieving the Sustainable Development Goals (SDGs), many are recognising the key role of food systems. They are not only critical in ensuring food security and improved nutrition—food systems are important in achieving social, economic and environmental goals as well.

Theme: Politics and ethics. The topic question you have to focus on

Theme: Politics and ethics. The topic question you have to focus on and find DIFFERENT PERSPECTIVES ON is: To what extent is there still a valuable purpose for having US military forces in Afghanistan at almost a time span of two decades?

In the intro paragraph give context in why we are there initially there and go over a brief history of the Russians that used to be there and so on.
In different paragraphs go over different perspectives you discover from your sources, but make sure the sources come from scholarly articles too not just websites (but you can use reliable news websites).

Make sure to include other COUNTRIES effects not just the US’s that are effected from them fighting in Afghanistan.

For example a PERSPECTIVE might be what happens to China’s economy if they come over to Afghanistan and US forces leave.

Another PERSPECTIVE to talk about is The US military in Afghanistan is there in order to keep an indirect watch over Pakistan to make sure their nuclear arms don’t fall under the wrong hands like terrorists groups.

In a perspective talk about how if the US leaves Afghanistan it would create a power vacuums.

You can talk about how US citizens have been taxed for too long for this war and what other things that tax money could have been used for.

Talk about the possibility if US forces leave Afghanistan that is unfair to Afghani forces who are lefts defenceless to fight against terrorists groups for themselves.

Make sure to include those different perspectives in different paragraphs throughout the research paper. Also include whatever other perspectives you find that offer a valid point that you think is worth writing about.

The last paragraph however has to be a reflection of your perspective. How writing this paper sort of changed your perspective by looking at other people’s. What could people accomplish through the future looking at Troops fighting in Afghanistan. What further research could have been done.

Make sure to include statistics and facts in this paper, like civilian casualties in Afghanistan US troop deaths etc.
Here are some sources helpful but feel free to use your own.

 

Use sources from foreign countries as well.

Always keep the topic question in mind.
