...Command Design Pattern Agenda * What is the Command Desgn Pattern (CDP) * Object Interaction and Command Object Hierarchy * Command Pattern generic UML * Recorded demonstration * Java example code * What are the benefits/drawbacks of the CDP The intent of this presentation is to provide a walk through and recorded demonstration of the command design pattern. What is the Command Design Pattern? * A Behavioral design pattern * An object is utilized to represent and encapsulate information * The information includes method name, object owning method, and method value parameters * The information can be called immediately or at a later time The command pattern is a behavioral design pattern in which an object is utilized to represent and encapsulate information (Banas, 2012). The interesting thing about the command design pattern is that it can allow one to store lists of commands which can be called immediately or at a later time. What is the Command Design Pattern? * Client specifies which command to run when the execute() method is invoked on one of the encapsulated methods * An object named “Invoker” transfers the Command to a separate object named “Receiver” which executes the correct code The command pattern allows the client to determine which command to run when the execute method is invoked in the command interface (Kuchana, 2004). After the command is “invoked” to execute, he concrete command that is identified transfers...

...Incident Command System EMC310 Incident Command System This scenario will focus mainly on the securing, treatment, triage, evacuation, and relocation and tracking of the 95 elderly individuals and removing the most critical and environmentally effected individuals by ambulance to a secure, stable, and warm environment followed by the ambulatory individuals can be assisted to the larger transports of busses and vans to be removed to a more stable, secure, and warm environment. “local emergency managers must consider the needs of certain "vulnerable groups" - people within the community who are especially susceptible to hazards (Morrow 1999). The Memory Center is facing extreme weather conditions due to a rainstorm that knocked out the cities power, and the failure of its generator. There are 95 elderly men and women living in the center who are feeling the effects of the temperature dropping. The emergency manager has many decisions to make while ensuring the safety of the Memory Center residents. Each level of the Incident Command System (ICS) must be alerted. Some of their tasks will be covered below to show what their responsibilities are. A brief description of ICS The Incident Command System is a system for controlling all of the necessary components of incident management in a well-organized and efficient way. The primary purpose is to allow resources, such as equipment, personnel, and communications, across multiple agency jurisdictions...

...Command And Control In Public Services Command and control is used within all public services in order to carry out tasks/operations in an effective, efficient and proper manner. Without command and control, the public services would not function properly and the employees within those public services would not be able to carry out their roles and responsibilities properly. It is important that all public services employees are over trained in their job just in case they need to work in a situation on their own without anyone else telling them what to do. For example, if a member of the ambulance service is by himself/herself and comes across an individual who has been run over, they must know exactly what to do and how to cope alone, and this is an example of why it is important for the public services to be over trained in their job. Every public service carry out different roles and responsibilities and it is through command and control that the individual is able to carry out their daily tasks in an effective and efficient way. Command and control ensures that the individual knows EXACTLY what their job entails and it ensures that the individual is fully trained and over trained in the job they specify in. Command and control in the Army is highly important for military exercises such as drill practise/competitions. The individual in charge of the military exercise e.g. Sergeant Major, must have good command and control over the soldiers in order for the soldiers...

...the Incident Command System (ICS) was developed “in the aftermath of a devastating wildfire in California” (NIMS, 2004) in 1970. During the fire “16 lives were lost, 700 structures were destroyed, and over one-half million acres burned” at the expense of “$18 million per day” (NIMS, 2004) in overall costs. The responding agencies worked as well as they could together but they had many communications issues. Three years after the incident, in 1973 a system known as “FIRESCOPE” (NIMS, 2004) (Firefighting Resources of California Organized for Potential Emergencies) was developed. This is where the ICS and Multi-Agency Coordination System (MACS) were developed. Soon there was “agreed upon ICS common terminology and procedures and conducted limited field-testing of ICS” (NIMS, 2004) the system was used on several fires and adopted by the Los Angeles Fire Department. During the 1980’s it was realized that the ICS could be used on many different large scale incidents to manage personnel and so all responders used the same terminology to create easier communications between responding agencies. Characteristics of the ICS include: • Common Terminology • Modular Organization • Management by Objectives • Reliance on an Incident Action Plan • Manageable Span of Control • Pre-designated Incident Mobilization Center Locations & Facilities • Comprehensive Resource Management • Integrated Communications • Establishment and Transfer of Command • Chain of Command and Unity of...

...NIMS and the Incident Command System The way this nation prepares for and responds to domestic incidents is about to change. It won't be an abrupt change; best practices that have been developed over the years are part of this new comprehensive national approach to incident management known as the National Incident Management System (NIMS). But it will change � and for the better. Developed by the Department of Homeland Security and issued in March 2004, the NIMS will enable responders at all jurisdictional levels and across all disciplines to work together more effectively and efficiently. Beginning in FY 2006, federal funding for state, local and tribal preparedness grants will be tied to compliance with the NIMS. One of the most important 'best practices' that has been incorporated into the NIMS is the Incident Command System (ICS), a standard, on-scene, all-hazards incident management system already in use by firefighters, hazardous materials teams, rescuers and emergency medical teams. The ICS has been established by the NIMS as the standardized incident organizational structure for the management of all incidents. Although many agencies now use various forms of ICS, there...

...The Incident Command System is a “standardized management tool for meeting the demands of small or large emergency or nonemergency situations” (). The Incident Command System has become the standard for emergency management across the country. The great thing about ICS is that it is flexible and it can be used for any incidents and events that are from natural disasters to even acts of terrorism. ICS allows effective communication and efficient incident management, by allowing all different personnel, facilities, equipment, and procedures to operate within a common organizational structure. Now, when it comes to an Incident Action Plan, it is what “specifies the incident activities, assign responsibilities, identify needed resources, and...

...Labs Lab 4.1: Using Linux Command-Line Basics What is the purpose? This lab demonstrates how to redirect data from a process and how to identify and kill a process. What are the steps? • Task 1: Redirecting and piping standard output Procedure 1. Obtain a list of files from the home directory, including the hidden files. Redirect the output to a file named Listing by using the ls -a > listing command. 2. Obtain a long list of files, including the hidden files, and append the output to the same file. 3. Use the cat listing | less command to view the file and pipe the output to less. 4. Use the cat command to view the file again. However, this time, pipe the output to lpr to print the file. 5. Redirect the output of ls to the special file /dev/null. What happens? It’s redirected to dev/null Why? It’s null. • Task 2: Putting tasks in the background and terminating the job Procedure 1. Use the tail –f command to view your listing file from the previous task. The –f option tells tail to follow changes; therefore, the file will continue to run this command until you cancel the command by pressing Ctrl+C. Put the file in the background using the tail -f listing & command. You may need to press Enter again to view the command prompt. 2. Put the process in the background and display the prompt again. Run the top command in the foreground. This will provide you a list of your top 20 processes by CPU usage. Put this list in the background and stop it by pressing...

...The Incident Command System (ICS) is a incident management program that was implemented so disaster responders could have organized structure within the complexity and demands of incidents without over stepping boundaries of other organizations. The staff within the command are in charge of health and safety as well as public affairs. First in the line of command is the Information Officer, who develops and puts out the details of the incident to the media and other agencies. Next in line is the Liaison Officer who is the point of contact for organizing the work between the Incident Commander and Unified Commander. Last in command is the Safety Officer who’s job is to give advice to the IC and UC about personnel health and safety as well as...

...Within the excerpt, Ivan Fyodorovitch discusses a few aspects of what I believe to be the divine command theory. In the divine command theory, “mortal truths are determined solely by God. What makes an action required, wrong, or permissible is determined by (and only by) God’s commands regarding that action.” Everything that is deemed “wrong,” is forbidden by God. Everything that is “right,” is required by God. I do believe Ivan touches briefly on the divine command theory. “Ivan Fyodorovitch added in parenthesis that the whole natural law lies in that faith, and that if you were to destroy in mankind the belief in immortality, not only love but every living force maintaining the life of the world would at once be dried up.” In this quote...

...The divine command theory is the belief that God commands individuals to do specific things because they are deemed right. Divine authority is not a convincing starting point for justifying moral claims. Firstly, we, as individuals cannot determine or deem God as morally superior compared to us. “Yet another troubling implication of the Moral Grounds version of Divine Command theory is this: if there are no objectively right standards to which God necessarily adheres in commanding what He does- if, that is, moral standards are simply a function of God’s naked will- then his commands become wholly arbitrary” [DE, p. 99]. As mentioned, if guidelines as to what God considers right are nonexistent, then his commands are unsupported and irritational....

...Apply the Ethical Decision Making Method at Small Unit Level 158-C-1230 FM-1 FM 6-22 AR 600-100. Performance Steps: 1. Clearly define the ethical problem. SFC Sharp failed to shred secret documents that he personally marked as shredded. SGT Day is trying to cover for SFC Sharp and is encouraging me to look the other way. 2. Employ applicable laws and regulations. The unit commander and the unit’s standard operating procedure will determine if the documents were mishandled. SFC Sharp recorded the destruction of the book theses pages were from but the commander and proper personnel can determine if misconduct occurred. My responsibility is to report any questionable or unsafe acts. 3. Reflect on the ethical values and their ramifications. FM 1-60 States: “The Army is a values-based organization (Loyalty, Duty, Respect, Selfless Service, Honor, Integrity, Personal courage). It upholds principles that are grounded in the Constitution and inspire guiding values and standards for its members.” FM 1-61 builds on the value based ethics by stating: “The Army Values are the basic building blocks of a Soldier's character...

...Discipline is the glue that holds a combat team together. Without it there is no unit cohesion, no espirit de corps, no coordination. However, discipline is a complex product of training, leadership, and respect. It is respect which creates devotion to the team, and the important part is that that respect flows both up and down the chain of command. A leader respects the skills, strengths, and sacrifices of the people who work for him, and by giving that respect, in time and with effort, his troops come to respect him as well. That respect grows into devotion: the devotion of the leader to his troops, to do his best to see them through tough times and bring them home to their families, and the devotion of the troops to accomplishing the tasks of their unit under the vision of their leadership. Disrespect, however, has exactly the opposite effect. If a leader disrespects his troops, he fails to earn their respect and therefore fails to create devotion to the team. His attitude will be noticed and will become detrimental to morale, which in turn will hurt the combat effectiveness of each troop as well as the whole. Because he cannot respect his troops, he will also fail to recognize their true strengths and employ his forces to the best of their respective abilities. If, on the other hand, a troop fails to form respect for ANY leader, no matter how good that leader is at their job, then that troop forms a sort of uprising point... a point of discontention that saps unit...
