Suppose Alice, Bob, and Carol want to use secret key technology to authenticate each other. If they all used the same secret key, K, then Bob could impersonate Carol to Alice (actually any of the three could impersonate the other to the third). Suppose instead that each had their own secret key; so Alice uses KA, Bob uses KB, and Carol uses KC. This means that each one, to prove his or her identity, responds to a challenge with a function of his or her secret key. Is this more secure than having them all use the same secret key? Hint: What does Alice need to know in order to verify Carol’s answer to Alice’s challenge?

Assume a cryptographic algorithm in which the performance for the good guys (the ones that know the key) grows linearly with the length of the key and for which the only way to break it is a brute-force attack of trying all possible keys. Then, suppose the performance for the good guys is adequate (e.g., it can encrypt and decrypt as fast as the bits can be transmitted over the wire) at a certain size key. Finally, suppose advances in computer technology make computers twice as fast. Given that both parties— the good guys and the bad guys— get faster computers, does this advancement in computer speeds work to the advantage of the good guys? The bad guys? Or does it not make any difference?

Explain research and theories of cultural and linguistic diversity and equity that promote academic and social language learning for ELLs. Describe three ways ESL teachers can advocate for ELL families and act as a professional resource in the educational community. Include examples that highlight the leadership role of ESL teachers.

 Assessment Description
Advocacy is an essential and expected part of working with ELLs and their families. Teachers may find it necessary to advocate not only for the individual students in the classroom but also to address larger systemic issues where inequities in education might still exist.
Imagine you work in a school where there has been a turnover in school board members. The previous board was less than receptive to addressing the needs of ELLs in the school community. With the new school board members, you have a chance to bring awareness to a specific issue affecting ELLs and their families.
Part 1: Making a Proposal
Research examples of school board proposals and issues that affect the learning of ELLs to make a request to the school board in the scenario. 
Note: Since this is a fictional proposal, you may create further school context as needed, to complete the assignment.
Write a one-page proposal to submit to the school board advocating for a new policy, program, or action to address your selected issue. Include the following in your letter:

Background or introduction of the issue, including rationale of the issue’s importance and how it promotes learning for ELLs.
Proposal of a new policy, program, or action that you would like the school board to support or approve regarding the issue.
Research and data supporting your proposal, cited and briefly summarized. Include a minimum of three scholarly resources.

Part 2: Summary
In a minimum of summarize the importance of advocacy and professionalism as an ELL educator. Include the following in your summary:

Explain research and theories of cultural and linguistic diversity and equity that promote academic and social language learning for ELLs.
Describe three ways ESL teachers can advocate for ELL families and act as a professional resource in the educational community. Include examples that highlight the leadership role of ESL teachers.
Discuss your plans for professional growth through future advocacy work that supports the language development and academic achievement of ELLs, the rights of ELL families, and the advancement of the TESOL profession.

Support your summary with a minimum of three scholarly resources.
Note: These resources are separate from the resources included in your proposal.
Submit your proposal, summary, and resources in a single document.
While APA Style is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA formatting guidelines.

Evaluate at least two work motivation theories and how they can be applied in order to improve employee recruitment and retention at JC’s Casino. Examine possible occupational stressors that are negatively influencing recruitment and retention. What improvements would you suggest to alleviate these stressors?

Read the following scenario:
You are an independent consultant who has recently been hired by JC’s Casino to help improve retention issues concerning the dealers and housekeepers. Most of the dealers have been leaving the casino to work at other casinos in the area, even though JC’s Casino pays better than their local competition. On several exit interviews, many of the dealers have cited the pit boss, Joe, as being “toxic, overbearing, evil, and incompetent.” Joe is the casino owner’s step-son and the HR director, Tom Sneed, is afraid to confront the owner.
Among the housekeeping staff, there has been an above normal rate of absenteeism and high turnover of rooms. Many of the managers who work in accounting, payroll, and other departments have had to ask their full-time employees to help cover for housekeeping by cleaning rooms periodically. Because of this problem, the hotel has had to adjust their check in times from 3 p.m. (the industry standard) to 6 p.m. Customers have arrived earlier and the hotel has had to accommodate them by creating a room to hold luggage. They have also had to hire staff to man the luggage room.
The director of housekeeping, Andrew Keehn, has been working hard to add more staff but he states “good help is hard to find.” The housekeeper’s current hourly wage is comparable to other casinos in the area but because of the staffing shortage, the housekeepers have to clean more rooms per day than their counterparts. The casino owner only knows that there are some issues with keeping the dealers and that some customers were upset because they had to wait to check in. You have been hired for a quick fix and your suggestions were needed yesterday.
 
Write apaper in which you identify each issue and make recommendations to JC, the casino president, on how to improve overall retention. What the scenario does not provide, you can create. Be sure to include the following in your assessment:

Evaluate at least two work motivation theories and how they can be applied in order to improve employee recruitment and retention at JC’s Casino.
Examine possible occupational stressors that are negatively influencing recruitment and retention. What improvements would you suggest to alleviate these stressors?
Examine the role of job satisfaction and its influence on retention at the casino. Provide recommendations for improving job satisfaction of the employees and how that can play a part in successfully improving retention.
Discuss counterproductive employee behavior occurring at the casino. What suggestions would you make to reduce the counterproductive behavior and increase productive employee behavior?

Include at least three references.
Format your paper consistent with APA guidelines.

What strategies for socialization would you implement to increase the probability of new recruits joining the CVPD? What problems would you anticipate with the proper socialization of the new employees?

Instructions
Many law enforcement agencies are facing an increasingly problematic shortage of police officers due to management difficulties that have been worsened by the existing police subculture, politics, power struggles, and organizational conflicts.
Problems at the CVPD
You are a recruitment officer at the Centervale Police Department (CVPD). There is a new problem being faced by your police department and those around the country. However, the problem seems to be more pronounced in the CVPD. There seems to be a huge difficulty in recruiting new officers. This is because there are very few applicants for the job and a large number of vacancies. This has never happened before.
It appears as though officers are reluctant to join the CVPD. LA has a high rate of crime and not enough staff to control the crime. The superintendent of the CVPD appointed a research team to find out why individuals were opposed to joining the CVPD. This is what the team found:
In an effort to restructure the police force, there is a sudden absence of well-defined roles. New members of the department are confused about the roles they are required to play. Most of the time, there is too much work pressure because they are required to perform functions beyond their expertise. Sometimes, there is no work at all. This causes low morale and low job satisfaction within the employees.
Another significant finding of the research done was that there is an abuse of power in the police force. Recent employees have reported that the sergeants tend to misuse the power they have. Not only do they expect the new employees to obey them blindly, but they also make unfair demands. For instance, three new police officers were put on night patrol duty for three months. During these three months, they were made to do 72 hour shifts on many occasions.
A very crucial finding was that the new employees who have joined the police force as part of the family tradition are disillusioned with the changes in policing. They are not prepared for the new attitude toward policing and the new policies that have developed.
For this assignment you are the recruitment officer in the Centervale Police Department (CVPD), you have been given the responsibility of helping CVPD solve the problem mentioned above. The empty positions in the department need to be filled as soon as possible. To do this, changes have to take place within the organization.
You have to come up with a plan to solve the problem. You need to conduct an analysis and present a report. Your analysis and conclusions should focus on solving the recruitment problems in the CVPD. Your analysis should explore how the CVPD posts can be filled with new and aspiring police officers. In your analytical report, include the following:

What strategies for socialization would you implement to increase the probability of new recruits joining the CVPD? What problems would you anticipate with the proper socialization of the new employees? 
What types of power would you attempt to implement within the CVPD to improve the administration of the police department? Why would you choose these types of power over others?
What plans would you put in place to reduce the intraorganziational and interorganizational conflict in the CVPD?
