Learn about the story of Stuxnet.  Explain why this is different than anything that came before it. Speculate about whether it was a wise or unwise move to utilize such a tool, and explain why.

Here are some starter links but you are certainly encouraged to find your own information and bring it back to the group and share.

If you have cable TV you may see a documentary called Zero Days (2016), or find pieces of it on Youtube. If you have time, there is a very interesting explanation there from some people who are the cutting edge when we talk about Homeland Security.

                                             CLASSMATE’S POST

The Stuxnet development was different than any previously created virus or worm malware because it is not spread via the internet, rather it is primarily spread to a computer control system via a USB stick. Stuxnet primarily impacts and infiltrates  Windows computers, but interestingly enough, does no actual damage to the Windows system itself. Stuxnet looks for a specific “Programmable Logic Controller”, an operating system made by Siemens that controls engineering functions and different automated processes in industrial facilities, chemical plants, and nuclear power stations (forbes.com).  

I found Stuxnet to be particularly interesting because of the manner in which it is spread and the fact that, if two Stuxnet viruses find each other on an operating system, they evaluate each other to ensure they are both running the most up to date software and if not, update so that they are. Its believed that Stuxnet has infected well over 50,000 Windows operating computers, and based on the specific functionality, it does appear that the virus targets a specific PLC system and that the creators of Stuxnet were fully aware of what they were after when creating it. The highlight of the discovery of Stuxnet was it’s use to infect the operating systems of the Iranian Nuclear power plant Bushehr. It is highly speculated that either the United States or Israel was behind the creation and deployment of Stuxnet on the Iranian plant in order to disrupt their actions and nuclear program. 

I find Stuxnet to be an extremely useful cyber tool when used appropriately, especially in defense applications. The utilization of such technology by governments in order to shut down rogue or enemy operations, specifically of potential terrorist operations could be substantially useful.

Unit 4 discussion board criminal justice

 

The Discussion Board (DB) is part of the core of online learning. Classroom discussion in an online environment requires the active participation of students and the instructor to create robust interaction and dialogue. Every student is expected to create an original response to the open-ended DB question as well as engage in dialogue by responding to posts created by others throughout the week. At the end of each unit, DB participation will be assessed based on both level of engagement and the quality of the contribution to the discussion.

At a minimum, each student will be expected to post an original and thoughtful response to the DB question and contribute to the weekly dialogue by responding to at least two other posts from students. The first contribution must be posted before midnight (Central Time) on Friday of each week. The original contribution must reference the text or auxiliary reading at least twice. Two additional responses are required after Friday of each week. The responses must be posted on separate days and must be at least 200 words in length. The responses are due by midnight (CST) Tuesday. Comments that are posted late on the last day of the week, are not quality responses and will be graded down. Comments that are mere responses (I agree!) will also be graded down. Students are highly encouraged to engage on the Discussion Board early and often, as that is the primary way the university tracks class attendance and participation.

The purpose of the Discussion Board is to allow students to learn through sharing ideas and experiences as they relate to course content and the DB question. Because it is not possible to engage in two-way dialogue after a conversation has ended, no posts to the DB will be accepted after the end of each unit.

Yes. My door is always open for other opportunities. Working overseas gives me a chance to work with other people coming from different backgrounds and with this, this will provide me with a chance to develop cross-cultural communication skills and will force me to create stronger communications skills and confidence as I progress in my career.     

Taking an overseas job or living abroad is a challenging experience as you will have to adapt to a new culture and a new way of living. For me, the county that I feel like I am not comfortable, and I think I would not dwell in is China. China invaded my country Philippines one thousand years ago, and up to now there presences still existing in our country. They have China town in the Philippines were in all rich Chinese business people living and running their business.  

During my college days, my professor gives us the assignment to search and observe how Filipino people work with Chinese people. So I went to China Town located in Binondo Manila, Philippines. And I interviewed one of the sales ladies how they are doing in terms of salary and benefits and the treatment. Out of ten participants, only three sales lady says they have treated well the rest they have no choice but to deal with common derogative words, and the salary and benefits are not enough.    

Based on the citing official statistics, average migrant worked in 8.8 hours each day, and 85% of the migrant worked 44 hours a week, and they only earned 350 dollars per week (Lin, 2013). Aside from that, According to the Wall Street Journal, China often exploited migrant workers and the common complaints are over fatigue, insomnia, lack of energy, and frequent illness (Lin, 2013). Based on the research I have done these are the reasons why I am not comfortable to work in China.

Introduction

 Think back to the first day you started at your job, were you nervous?  Did you know what to do or how to act?  Most people know how to act, but what should a company do to ensure all their employees are on the same page with how to act?  The answer is issuing a code of conduct.

Purpose of a Code of Conduct

 First we have to ask ourselves, what is a code of conduct?  A code of conduct is “ a written document called a code of conduct, or code of ethics, that sets the tone of core values and ethical guidelines for employees. This document will establish the guiding principles of behaviors and decision making of all employees” (Board, 2015).  In establishing a code of conduct, companies are giving their employees a physical document to check their behavior to the employer’s expected standard.  This will help employees determine if their behavior is ethical or unethical and should help reduce the number of instances of unethical behavior.

Why is it Important to Have a Code of Conduct?

 A code of conduct is important for many reasons.  If your company is public, it is by law required to have one.  “ A well-written code of conduct  clarifies an organization’s mission, values and principles , linking them with standards of professional conduct” (ECI, 2018).  “Additionally, a code is a  central guide and reference for employees  to support day-to-day decision making” (ECI, 2018).  A company’s code of conduct is important for internal decisions and day to day operations, but also externally it allows customers, investors, and anyone else who views the company to understand the behaviors, guidelines, expectations, and vision of the company.  A company with a strong ethical code of conduct will likely have success over the long term with fewer incidents and will be highly regarded in the community over a company that lacks or has a weak code of conduct.

Issues to Address in a Code of Conduct

 There are many things that should be covered in a code of conduct.  Since there will be so many things covered, and employers want their employees to understand what they are stating, they need to, “ Create the code of conduct with language that is as clear as possible. Examples may include prohibitions on illegal activities, smoking, drinking, foul language, discrimination and harassment. You may also include confidentiality expectations, procedures for calling in sick, expected dress and appearance and reporting procedures for emergency situations. (McKay, 2018).  From previous experience, the companies I have worked for have had codes of conduct that include, tobacco use, drug policies, dress code, expected behavior inside work, expected behavior outside of work, attendance policies, sexual harassment clauses, and many others.  It is a basically guideline of how to look, feel, and act.

Evaluate a Code of Conduct

 The company I currently work for has a very detailed code of conduct.  It address sick leave, vacation, excused absences, unexcused absences, FMLA, dress code, drug policy, sexual harassment policy, discrimination policy, expected behaviors inside and outside of work, and many other subjects.  Spirit employees almost 14,000 people at locations throughout the world, so as a result they have written a very detailed and extensive code of conduct to try and eliminate any gray areas or areas that haven’t been covered that could leave the employees or the company vulnerable.  This is a great policy to me because everyone has the same information and is put on a level playing field.  I have been treated with more dignity and respect at this company than any I have ever worked at before which in turn has made me buy into the company’s values and want to work even harder.  It has made me feel like I have found my career home rather than just working a job.

Conclusion

 Writing a code of conduct can be time consuming as it must cover as many possible aspects as leadership can think of.  However, this might be one of the most important things a company can do.  Internally it shows the vision and expectation the company has, externally it helps build a reputation in the community and the world.  A positive strong code of conduct will help lay a strong foundation for a company to succeed.

Clients will likewise be consoled that they are working with an organization that qualities uprightness and that honesty will be utilized when leading business.

 What issues ought to be viewed as incorporated into a set of accepted rules, particularly given the merger situation?

 The set of accepted rules ought to incorporate proposals from every significant office utilizing recommendations to ensure that it reacts to the fundamental hazard territories. It should represent the distinctions over all divisions. It ought to incorporate exceptionally vital subjects that are basic for the association, it ought to be custom fitted to fit the specifics of the hierarchical business, qualities and culture. It should address the majority of the state and government laws that include separation, provocation, irreconcilable situation, pay off, extortion and deception, and appropriate records keeping. It ought to likewise address how workers are found in the network. Above all, it ought to incorporate a letter from Theresa and Mike portraying the significance of the set of accepted rules and how it will be authorized.

 For 19 years I have live by the Army and it has a very specific code of conduct. It is composed in a straightforward simple to peruse and comprehend shape which if violated can be punished under the uniform code of military justice. The Code of Conduct or ‘set of principles’ is an arrangement of standards plotting the social standards and guidelines and duties of, or legitimate practices for, an individual, gathering or association. Related ideas incorporate moral, respect, moral codes and religious laws AR 350-30 (2018).

Qualitative and Quantitative Research Analysis

Below is an example of a mixed methods approach to considering one element of the post-Katrina response.

Problem statement: This researcher is interested in studying posttraumatic stress disorder (PTSD) in soldiers who deployed to the area from the 82nd Airborne Division, as compared to experiences they had in combat operations prior to Hurricane Katrina. The researcher wants to examine whether they experienced greater trauma helping Americans in trouble than they do on distant battlefields.

The researcher intends to use survey instruments with carefully crafted questions, the answers of which she can numerically collate and process. After all of the data is processed, she intends to follow up with selected soldiers based on their answers by speaking to them personally and conducting conversational interviews.

Primary Task Response: Within the Discussion Board area, write 400–600 words that respond to the following questions with your thoughts, ideas, and comments. This will be the foundation for future discussions by your classmates. Be substantive and clear, and use examples to reinforce your ideas:

  • Critically evaluate the problem statement. Is this a problem that can be undertaken or answered with the instruments she has listed she intends to use? Why or why not?
  • What other techniques or instruments do you recommend she add to her intended tools? Why?
  • Do you feel there is information missing? 
    • If so, what information do you think is necessary? Why?
    • If not, how is the information sufficient? Explain.

“A” WORK DISCUSSION IN 15 HOURS

Most criminal justice agencies have some version of an internal affairs (IA) department. Hollywood has long portrayed IA as the enemy, investigating and looking to reprimand their own brothers and sisters in law enforcement, corrections, and the courts. Personnel who talk or report issues to IA are often characterized as rats or snitches, and there is said to be an unwritten rule known as the blue wall of silence.

Do you believe IA should be as concerned with the law enforcement officer who fails to report a known ethics violation versus the person suspected of the ethics violation? Should they (if proven to be guilty) both be reprimanded? Explain your position.

 CLASSMATE’S POST

Well, wrong is wrong.  In our police department we have a policy and procedure, P&P III 3.3.2 which states “All personnel are required to report any observation or information received which constitutes violation of the written directives of this department.”  The problem is that there are many different levels of “wrong.”  If any officer is committing crimes on or off duty, then I absolutely expect it to be reported.  We have taken an oath to protect and serve and in no way are we above the law.  Now when it comes to things on a smaller scale of wrong, I think we all look the other way when an officer uses salty language or rolls a stop.  And yes, anyone who does come to supervisors with these things are called rats.

While I was working as a canine handler, I was at a 7-11 grabbing a soda and was getting the cold shoulder from the clerk.  I asked her what her problem with me was, she told me that she thought we all did not like her because she reported misconduct by one of our detectives.  When she told me what he had done, I was horrified and told her that not only I, but all of us admired her for her courage to come forward to report a dirty cop.  It turns out that this guy was window peeping her and then served a fake search warrant to her apartment off duty on his own time.  She ended up being one of many women who reported similar accounts against this detective.  Not only did we fire him, he was investigated criminally, and the case was sent to the prosecutor’s office.  It was my supervisor on third shift that had the courage to do the right thing and put a stop to this detective’s behavior.  If my supervisor would not have had the guts to do the right thing, he would have been just as guilty for letting this happen and if these escalated to these women being assaulted, our department could have been on the hook.  Aside from that, it would be a terrible thing to live with knowing that you could have prevented it.

I believe that if the violation is serious enough and if the violation is a felony, the person who had knowledge and failed to report it should be disciplined as well.  These are tumultuous times and with the public having a compromised trust in the police, the police must do the right thing and hold those responsible for misconduct accountable.  I have always said if you can’t trust the police, you can’t trust anyone.
