Ethics Discussion

/in /by

Required Resources
Read/review the following resources for this activity:

  • Textbook: Chapter 13
  • Lesson
  • Minimum of 1 scholarly source (in addition to the textbook)

Introduction
Some people believe that you can tell who a person is by what they do when no one is looking. Let’s look at the following case. John Doe, a nurse, has downloaded an application to her phone that allows him to download copyrighted textbooks for a nursing course (that Doe is going to take) without his Internet Service Provider knowing it. The application is called “Cloak” as in cloak of invisibility (a hooded coat one wears to make it so others cannot see you). The application disguises his phone and makes it so the information on it is inaccessible. John is aware that other people who are of a lower socio-economic status (like him) also use this software program for the same reason (and to save money). John Doe knows that his religion forbids him from using this application to download in this manner. John Doe is focused on his own economic situation and does not consider the publisher, author, and others involved in the books. Think about a course of social action; what social values should be used to address this moral issue and conflict.

  • Initial Post Instructions
    Create a personal ethical philosophy and explain from which philosophy or philosophies (it must include at least one of the following: virtue ethics, Kantian ethics, utilitarianism, virtue ethics, or social contract ethics) you created it and why the contents are important and meaningful for you. List its precepts.
  • Take your personal ethical philosophy statement and use it to work through John Doe’s case. What is moral and immoral per your theory?
  • How would the veil of ignorance or a different theory of justice address John Doe’s case?

Follow-Up Post Instructions
Respond to at least one peer. When possible, respond to a peer who chose a different ethical theory than you did in your posting. Further the dialogue by providing more information and clarification.

Writing Requirements

  • Minimum of 2 posts (1 initial & 1 follow-up)
  • Minimum of 2 sources cited (assigned readings/online lessons and an outside scholarly source)
  • APA format for in-text citations and list of references

Hello Professor and Class, 

My personal philosophy is that I always make sure people are happy and put people before myself because in the long run when I am in need of help, they will remember the time I helped them and gave them happiness. “Kantian ethics provide a human-centric ethical framework placing human existence and capacity at the centre of a norm-creating philosophy that guides our understanding of moral conduct” (Ulgen, 2017). I believe Kantians ethics follows this philosophy I have because it is the moral thing to do in my mind to put people first and make sure happiness is covered all around. Helping and ensuring a person is a way of making that person the center and making sure they know they are existing. 

John Doe in my personal philosophy wouldn’t work out. Knowing it is against his religion, he went ahead and downloaded the app because he cant afford the books by himself. He cared more about himself and passing his classes than his religion and that I believe is morally right. The morally wrong thing to do is knowing other low income people have it and it works, then not downloading the help that he needs and failing his classes. Although downloading an app that disguises a phone is wrong, it’ll help John Doe in the long run. 

“The political philosopher John Rawls is well known for his thought experiment of the “veil of ignorance.” The thought experiment goes something like this: when designing rules for your society, you should be ignorant of what social position you yourself will occupy” (Gobry, 2015). This addressed John Doe’s case by doing what is best for himself. He knows he is low income and needs these books to be able to get through the classes but cant afford them. He knows other people have the same app and it works well for them. John Doe knows he needs this to succeed so he got the app so he won;t fail.

Experiment To Test The Effect Of Compost On The Development Of Root Crops

/in /by

Biologists designed an experiment to test the effect of compost on the development of root crops. They tested several different crops, including carrots, potatoes, beets, and onions. They grew most of the plants in the greenhouse, but due to space issues, they had to grow some outdoors. They gave all the plants the same amount of compost. They obtained the compost from a local farmer and from the local hardware store. They ran out of the farmer’s compost, so some of the plants received that compost when the seeds were planted and other plants got hardware store compost after the plants had already started growing.

RESULTS: Some of the roots seemed really big. Other roots seemed normal or small.

CONCLUSION: They couldn’t tell what the effect of the compost was because the results were inconsistent.

 

what is the dependent variable and independent variable in this experiment?

Virtual Lab: DNA and Genes

Worksheet

1. Please make sure you have read through all of the information in the “Questions” and “Mutation Guide”. If you come upon terms that are unfamiliar to you, please refer to your textbook for further explanation or search the word here: http://encarta.msn.com/encnet/features/dictionary/dictionaryhome.aspx

2. When you are ready, please close out the “Mutation Guide” and click the “Mutate” button that appears on the new page to begin the activity.

3. You will see the following:

· an “Original sequence” of mRNA that has been translated properly into its corresponding amino acid sequence

· a “Mutated sequence” that is blank

· a “Mutation Rules” block of information

4. Your task is to read the information in the “Mutation Rules” area and then apply the information to completing the “Mutated sequence” of mRNA and protein. To do this, you must:

· read the “Mutation Rule”

· look at the “Original sequence” of mRNA given

· determine the “Mutated sequence” of mRNA bases after applying the information presented in the “Mutation Rule”

· determine the “Mutated sequence” of protein (amino acids) translated from the mRNA sequence you just created using the “Genetic Code Chart”

5. Please complete this information in the area below BEFORE actually completing the virtual activity; you can then refer to it to help make the correct selections at each step. Remember to use the “Genetic Code Chart” to determine the protein sequence:

“Mutation Rule” states: ___________________________________________

Original Sequence:

mRNA

                                               
               

Protein

Mutated Sequence:

mRNA

                                                 
               

Protein

6. Once you have filled in the information above, drag the correct nucleotides

to their position in the “Mutated sequence” of mRNA. Then drag the corresponding amino acids into place in the “Mutated sequence” of protein. When you are finished, click “Check”. A message will appear in the open box at the bottom of the page indicating whether your answer needs to be corrected. You may repeat this entire activity by clicking “Mutate”.

7. Please finish this exercise by opening the “Journal” link at the bottom of the page and answering the questions.
