Why do many people believe that the world is a more violent, chaotic, and dangerous place than it is? Use and define at least two concepts from the readings in your answer.

The following jobs are waiting to be processed at the same machine center. Jobs are logged as they​ arrive:    

All dates are specified as manufacturing planning calendar days. Assume that all jobs arrive on day 275.

Assume each job starts at the beginning of the day and finishes at the end of the day​ (a job that begins on day 275 and takes 8 days will finish on day​ 282, and the next job begins in the morning of day​ 283). Compute all times based on initiating work on day 275.

​a) Using the FCFS​ (first come, first served​ ) decision rule for sequencing the​ jobs, the order is​ (assume that jobs came in the order in which they are listed in the​ table): ___A-B-C-D-E___

*The average tardiness​ (job lateness) for the sequence developed using the FCFS rule​ = ______ days ​(round your response to two decimal​ places).

*Calculate the percentage utilization for the sequence developed using the FCFS rule = _______ % (round your response to two decimal​ places).

​b) Using the EDD​ (earliest due​ date) decision rule for sequencing the​ jobs, to determine the order of the jobs​ (to resolve a​ tie, use the order in which the jobs were​ received).

*Calculate the average tardiness​ (job lateness) for the sequence developed using the EDD rule = _________ days (round your response to two decimal​ places).

*Calculate the percentage utilization for the sequence developed using the EDD rule = _______ % (round your response to two decimal​ places).

​c) Using the SPT​ (shortest processing​ time) decision rule for sequencing the​ jobs, determine the order of the jobs​ (to resolve a​ tie, use the order in which the jobs were​ received).

Part1: Write a program in C/C++ to solve the 0/1 knapsack problem using (i) Dynamic Programming based algorithm and (ii) Branch and Bound Search based algorithm Go through the related text and implement each of these algorithms using the efficient data structure. Show the results of different steps of these algorithms for an instance of the 0/1 Knapsack problem with number of items, n=4. The capacity of the knapsack, weights and profits of the items may be generated randomly with the condition that the capacity of the knapsack is such that all items can not be accommodated in the knapsack. But, at the same time, at least one item can be accommodated in the knapsack. Part2: Analyze the complexity of these algorithms (Run each of the two algorithms for a set of ten randomly generated 0/1 knapsack instances (with n=4) and compute the time taken by the selected implementation in each run. Compute average time taken by each of these two algorithms

Hi! I have some geology ?'s:

23. To account for the incredible distances traveled by some of the Columbia River Flood Basalts to reach the Pacific Coast, possible explanations include which of the following (more than one answer is recommended):

A. the pre-existing uniform gradual slope toward the Pacific Coast all across Oregon and Washington from their eastern borders to the ocean.

B. the initial high temperature of the lava from these eruptions.

C. the low viscosity of the lava from these eruptions.

D. the filling in of low topography by early flows, flattening the landscape for later flows.

E. solidifying and crusting over of the upper surface of flows, providing insulation to maintain high temperature and low viscosity of flows over great distances.

F. volcanic vents providing freshly erupting lava all along the Columbia River to the ocean.

G. the Oregon coast was much further east at the time of these eruptions, making the journey actually far shorter than it appears today.

24. The methods of monitoring used by USGS volcanologists to accurately predict the 1991 eruption of Mt Pinatubo in the Philippines and save thousands of lives included which of these:

A. seismometers revealing subterranean magma movements


B. sonar measuring tectonic ground movements


C. GPS to figure out where they actually were

D. watching snakes, frogs, chickens, and pigs


E. visual monitoring by flyovers to inspect lava effusions


F. gas spectrometers to measure volcanic de-gassing

G. satellite data to detect thermal anomalies

Write a class (and a client class to test it) that encapsulates a tic-tac-toe board. A tic-tac-toe board looks like a table of three rows and three columns partially or completely filled with the characters X and O. At any point, a cell of that table could be empty or could contain an X or an O. You should have one instance variable, a two-dimensional array of values representing the tic-tac-toe board.

This game should involve one human player vs. the computer (aka, it should be a one player game). At the start of each game, randomly select if the computer will play X or O and who (i.e. human or computer) will make the first move.

Your default constructor should instantiate the array so that it represents an empty board.

You should include the following methods:

a method that generates a valid play by the computer and displays the board after each play.

a method that requests a valid play from the human and displays the board after each play.

a method to display the tic-tac-toe board.

a method checking if a player has won based on the contents of the board; this method takes no parameter. It returns X if the "X player" has won, O if the "O player" has won, T if the game was a tie. A player wins if he or she has placed an X (or an O) in all cells in a row, all cells in a column, or all cells in one of the diagonals.

NOTE: Be sure to display the board after each move. You must provide clear prompts for the human player to select a space on the tic-tac-toe board.

Input Validation: Verify that all moves by the human player are to a valid space on the tic-tac-toe board. An incorrect choice should not halt or terminate the game. Also, no human vs. human mode should be included in the program. Just Human vs. the Computer is what the game should only involve.

Exercise Overview

Interpersonal skills refer to the ability to communicate with, understand, and motivate individuals and groups. Implicit in this definition is the notion that a manager should try to understand important characteristics of the work group(s) being supervised. Diagnostic skills help managers visualize and understand the most appropriate response to a situation. This also relates to assessing how various things are related to one another. This exercise will give you insight into the importance of both interpersonal and diagnostic skills as they relate to managing groups and teams in organizations.

Exercise Background

In other cases managers are promoted, transferred, or reassigned to a different job and take over an existing group or team. At one extreme they may inherit a highly functional and productive group; at the other extreme they may inherit a group that is dysfunctional and that has a lot of internal problems. And, of course, there are many potential possibilities between these two extremes.

Therefore, it is important that managers have the skills needed to carefully assess the current dynamics of a group in order not to create problems where none exists or to solve problems that do exist. The questions that follow focus on different scenarios in which such insights may be needed.

You have been appointed to lead a new team. The purpose of this team is to assess different potential locations for a new warehouse and to make a recommendation back to senior management. Your team has been given 30 days to make a recommendation. What type of team is this?

1. Management team

2. Quality circle

3. Virtual team

4. Problem-solving team

5. Work team

You have been appointed to lead an existing group. Your boss, who informed you of the assignment, made these comments: “These people have some real issues. They have been a problem for years. They stick together like family but never seem to get much work done.” Which of these would best describe this group?

1. High cohesiveness, high performance norms

2. Low cohesiveness, low performance norms

3. Low cohesiveness, high performance norms

4. High cohesiveness, low performance norms

Which of these observations is correct? Check all that apply.

• In some cases, managers may want to resolve or eliminate conflict.

• Conflict always decreases a team’s performance.

• In some cases, managers may want to control conflict.

• In some situations, managers may want to stimulate conflict.
