Case study crime scene | Science homework help

/in /by

In the attachment, you will find photographs of a crime scene that has some challenges. You will be asked to analyze these photographs and provide a paper (minimum 600 words) detailing the challenges and how, exactly, to overcome these challenges to process the crime scene safely. You should also explain in detail all of the safety issues at this scene, including the dangers to the processing personnel as well as explain how the CSI and detective personnel can examine the scene and recover evidence safely.

 

Note: Remember, it is a paper, therefore you need an introduction and a conclusion and a minimum of five references (make sure you cite in text and then list the references in APA in your bibliography at the end of the paper). 

 

a sequential search member function of sorted type has the following

/in /by

1. A sequential search member function of Sorted Type has the following prototype: void Sorted Type::Search( int value, bool & found);

a. Write the function definition as a recursive search, assuming a linked list implementation.

b. Write the function definition as a recursive search, assuming an array based implementation.

2. We want to count the number of possible paths to move from row 1, column 1 to row N, column N in a two-dimensional grid. Steps are restricted to going up or to the right, but not diagonally. The illustration that follows shows three of many paths, if N = 10:

a. The following function, NumPaths, is supposed to count the number of paths, but it has some problems. Debug the function.

int NumPaths(int row, int col, int n)

{

if (row == n)

return 1;

else

if (col == n)

return NumPaths + 1;

else

return NumPaths(row + 1, col) * NumPaths(row, col + 1);

}

b. After you have corrected the function, trace the execution of NumPaths with

n = 4 by hand. Why is this algorithm inefficient?

c. You can improve the efficiency of this operation by keeping intermediate values of NumPaths in a two-dimensional array of integer values. This approach keeps the function from having to recalculate values that it has already figured out. Design and code a version of NumPaths that uses this approach.

d. Show an invocation of the version of NumPaths you developed in part (c), including any array initialization necessary.

e. How do the two versions of NumPaths compare in terms of time efficiency? Space efficiency?

Romero and juliet theme | Literature homework help

/in /by

 

1.  THEMATIC DEVELOPMENT

 

We are reading Romeo and Juliet this week in order to better understand some of its more important themes and how these themes are deployed in the play.  Using some of the literary terminology that you have learned this week, identify one of the following themes and write about its development in the play.  Romeo and Juliet is about: class conflict; a dysfunctional society; patriarchal oppression of women; generational conflict; the pathology of violence in society; imagination vs. reality; the destructiveness of love; free will vs. fate.

 

 

 

2.  SCRIPT TO SCREEN

 

Choose one of the following film adaptations:

 

Gnomeo & Juliet (2011), Chicken Rice War (2000), Romeo Must Die (2000), Romeo + Juliet (1996), Romeo and Juliet(1968), Romeo and Juliet (1966), West Side Story (1961), Romeo and Juliet (1954), Romeo and Juliet (1936).

 

After carefully reading Romeo and Juliet the play, carefully watch one of the adaptations (you will need to rent the film from Amazon, Netflix, etc., if it is not on YouTube); it is better of you watch it twice.  Then compose a comparison and contrast of the play and film.  In what ways does the film change the play?  Remain faithful to it?  Bring it to life?  Make it relevant for modern society?  Offer a cogent thematic interpretation

Phi 103 week 4 discussion 1 – fallacies and biases

/in /by

Once you learn the names of the major logical fallacies, you will probably start noticing them all over the place, including in advertisements, movies, TV shows, and everyday conversations. This can be both fascinating and frustrating, but it can certainly help you to avoid certain pitfalls in reasoning that are unfortunately very common. This exercise gives you a chance to practice identifying fallacies as they occur in daily life. 

Prepare: To prepare to address this prompt, carefully read through Chapter 7 of our book, paying special attention to learning the names of common fallacies, biases, and rhetorical tricks. Take a look as well at the required resources from this week. 

Reflect: Search through common media sources looking for examples of fallacies. Some common places to find fallacies include advertisements, opinion pieces in news media, and arguments about politics, religion, and other controversial issues. You may also notice fallacies in your daily life.

Write: Present three distinct informal logical fallacies you have discovered in these types of sources or in your life. Make sure to identify the specific fallacy committed by each example. Explain how the fallacies were used and the context in which they occurred. Then, explain how the person should have presented the argument to have avoided committing this logical error. 

Guided Response: Read the fallacies presented by your classmates and analyze the reasoning that they have presented. Respond in a way that furthers the discussion. For example, you might comment on any of the following types of questions: Have ever seen or fallen for similar fallacies in your own life? Are any of the cases presented also instances of some other type of fallacy? Is there a sense in which the reasoning might not be fallacious in some cases? What can people do to avoid falling for such fallacies in the future?

Hlt-302 week 8 benchmark – spiritual needs assessment

/in /by

This assignment requires you to interview one person and requires an analysis of your interview experience. 

 

Part I: Interview

 

Select a patient, a family member, or a friend to interview. Be sure to focus on the interviewee’s experience as a patient, regardless of whom you choose to interview.

 

Review The Joint Commission resource which provides some guidelines for creating spiritual assessment tools for evaluating the spiritual needs of patients. Using this resource and any other guidelines/examples that you can find, create your own tool for assessing the spiritual needs of patients.

 

Create a survey to assess the subject’s spiritual need during the interview. The spiritual needs assessment survey needs a minimum of five questions that can be answered during the interview.  During the interview, document the interviewee’s responses.

 

Submit the transcript of the interview. The transcript should include the questions asked and the answers provided.  Be sure record the responses during the interview by taking detailed notes. Omit specific names and other personal information from the interview. 

 

Part II: Analysis

 

Write a 500-750 word analysis of your interview experience. Be sure to exclude specific names and other personal information from the interview. Instead provide demographics such as sex, age, ethnicity, and religion. Include the following in your response:

  1. What went well?
  2. What would you do differently in the future?
  3. Were there any barriers or challenges that inhibited your ability to complete the assessment tool? How would you address these in the future or change your assessment to better address these challenges?
  4. Describe the spiritual experience you had with your patient, family member, or friend using this tool. How does this tool allow you to better meet the needs of your patient?
  5. Did you discover that illness and stress amplified the spiritual concern and needs of your interviewee?  Explain your answer with examples.

Submit both the transcript of the interview and the analysis of your results.

 

Prepare this assignment according to the APA guidelines found in the APA Style Guide, located in the Student Success Center. An abstract is not required.

 

This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.

 

You are required to submit this assignment to Turnitin. Please refer to the directions in the Student Success Center.
