Discussion 3

/in /by

***All discussions need to be 4-6 sentences***

 

1“Use Case Description versus Activity Diagram”  Please respond to the following:

  • Compare a use case description and an activity diagram. Devise a scenario in which you would use a case description, and devise a scenario in which you would use an activity diagram.
  • Consider a system needed to store information about computers in a computer lab at a university, such as the features and location of each computer. Ascertain the domain classes that might be included within the domain model. Discuss whether or not you believe an entity-relationship diagram (ERD) would be a suitable model.

 

 

2“CPUs and Programming” Please respond to the following:

  • From the first e-Activity(below), identify the following CPUs: 1) the CPU that resides on a computer that you own or a computer that you would consider purchasing, and 2) the CPU of one (1) other computer. Compare the instruction sets and clock rates of each CPU. Determine which CPU of the two is faster and why. Conclude whether or not the clock rate by itself makes the CPU faster. Provide a rationale for your response.
  • From the second e-Activity, examine two (2) benefits of using planning techniques—such as writing program flowcharts, pseudocode, or other available programming planning technique—to devise and design computer programs. Evaluate the effectiveness of your preferred program planning technique, based on its success in the real world. Provide one (1) example of a real-life application of your preferred program planning technique to support your response.

 

eActivity:

  • Use the Internet to research the various features of the Central Processing Units (CPU) of one (1) or two (2) computers. Be prepared to discuss.
  • Select your preferred computer program planning technique, such as flowcharting or pseudocode. Use the Internet and Strayer Library to research whether or not the selected technique has proven to be successful. For example, take note of whether or not there has been any research that indicates labor hours and dollars that have been saved due to programs initially being written with a lower number of programming errors. Be prepared to discuss.

Unit 5: Science in the Bedroom: The Science of Sleep – Discussion

/in /by
Your Sleep Patterns

Everyone has their own internal biological clock that controls many bodily functions, such as telling you when you need to sleep. Some people are naturally morning people while others may be night owls, but everyone needs to sleep.

As you learned previously, there are both genetic and environmental factors that play a role in your life—these genetic and environmental factors also affect your sleep patterns. To this end, there are many biological influences and individual choices that you make that influence your ability to sleep.

Do some research to learn more about sleep and circadian rhythms through the following link:

Conduct some additional research on your own about sleep patterns and find at least one reputable source to cite in a post.

During the week address the following questions:

  1. Assess your own sleep habits and patterns.
    1. Are you getting enough sleep? Are you getting too much sleep?
    2. Is your sleep restful, quality sleep?
    3. What would you change about your sleep habits/patterns if you could? Why?
  2. Why is sleep important? Is all sleep created equal?
  3. What are circadian rhythms? How are they related to sleep and the biological clock?
  4. How do your sleep patterns change over the course of your life?
  5. Later in the week, compare your personal sleep assessment to a classmate who appears to have different sleep habits and patterns than you. What steps can you recommend to help improve their sleep? Be sure to provide a reputable source to support your recommendations.

Be sure to review the Discussion Board Grading Rubric provided in the Course Syllabus.

Bus330 Principle of Marketing

/in /by

 

It can be harder to sell an intangible service than a tangible product. After reading Chapter 3 of the text, pick one of the cells in Table 3.4: “Service Classifications” and name a service offered in that class—for example, business remodeling service under consulting and operations. In 200 to 250 words, describe a service in your chosen category in terms of the four ways a service is different from a product—its intangibility, inseparability, variability, and perishability. Propose a solution for sale that could be used as a point of competitive differentiation in a marketing campaign.

Genetic Drift can occur when:

1-[removed]  

an “unlucky” individual in a population does not reproduce, meaning some of their genes are not as frequently observed in the population’s “gene pool.”
[removed]2-  

a disaster of some sort wipes out a group of individuals from a given population, reducing genetic diversity because only a subset of the original genes of the population’s “gene pool” are left after the disaster.
[removed]3-  

an extreme wind event may move a species, say flying squirrels for example, from one habitat to another. The individuals who are blown to the new site have only a certain subset of genes from the original population’s gene pool, so the new population has a different genetic structure/gene frequency distribution.
[removed]4-  

when a population is completely obliterated locally, meaning no individuals are left. However, some individuals of the species may exist in other habitats.
