Your response should be four (4) double-spaced pages; refer to the “Assignment Format” page located on the Course Home page for specific format requirements.Part A For Part A of this assignment, you will apply the principles of operant conditioning to modify an existing behavior. Target a behavior to be modified, either an undesirable behavior that you would like to eliminate or a desirable behavior that you would like to strengthen.1. Generate a plausible explanation for why the problem exists.
2. Describe one (1) reason why you want to change the behavior and one (1) benefit the change will bring.
3. Carefully design a program for modifying the behavior, making sure to include all relevant conditioning principles incorporated within your plan (which might include the use of positive and negative reinforcers, punishment, shaping, schedules of reinforcement, modeling, extinction, stimulus discrimination or generalization, primary and secondary reinforcers, and so on.) Your plan should include three (3) steps.Part BDesign a series of test items that would indicate the different intelligences according to Howard Gardner’s theory of multiple intelligences. Provide one (1) original example of how you would test each of the eight (8) different intelligences.

What does the court mean when it says “Stare decisis is not an inexorable command; rather it is a principle of policy and not a mechanical formula of adherence to the latest decision”?

This case study assignment explores the concept of stare decisis and whether it is an inexorable command.

Access and read Is Stare Decisis an Inexorable Command?(https://media.pearsoncmg.com/pls/products/coco/criminal_law/125689897x/assignments/pdfs/criminal_law_handout_lesson_01.pdf

 

Please answer the following questions about the case study:

 What does the court mean when it says “Stare decisis is not an inexorable command; rather it is a principle of policy and not a mechanical formula of adherence to the latest decision”?

 What would it mean for the American system of criminal justice, if stare decisis actually was an “inexorable command” or a “mechanical formula of adherence to the latest decision”?

Your response should be at least 500 words (no less than 250 words for each question). Any sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying citations.

All references and citations used must be in APA style.

Ecoflask Assignments

The Ecoflask lab runs over two lab periods, and there are several assignments associated with this lab (see the lab

manual and syllabus). The Ecoflask journal is due the week before the practical (30 November 2015) and includes

the following assignments:

Observations: Conduct background research on ecosystem interactions and community ecology to gain an

understanding of pond ecology and nutrient cycling. Then, create a closed-system aquatic community (ecoflask) and

make observations of change over time. (See directions in Ecosystem Interactions lab handout)

Hypothesis: Write a complete scientific hypothesis, which includes a prediction statement, based on your

understanding of ecosystems and community ecology and the initial observations you made of the ecoflask. The

hypothesis should relate to the overarching theme of the lab: ecosystem interactions. Create a hypothesis that you

are interested in testing during this two-week lab activity.

Experiment: Choose an experimental treatment. Your treatment should allow you to test your hypothesis and draw

conclusions. The following are potential tests:  Nutrient limitation or supplementation

 Introduction of an aggressive predator

 Introduction of a non-native organism

 Increase or decrease of particular trophic resources Note: Control treatments can be provided by the instructor. Results: Observation table (all original data sheets) with a drawing and description, identification, count, location/niche, and

other relevant information of the organisms observed in your Ecoflask  Draw a picture and describe of each of the different organisms you encounter and try to identify them.

 Note the “niche” of the organism: the region of habitat it occupies (plant, water, dirt, etc)

 Note the approximate number of individuals of the organisms in the flask. Use a classification system that provides information within a range of abundance [e,g,. absent (0), rare (1-5), moderate (6-15), widespread

(more than 15) — you may design your own method of quantification based on what you observe].

 Use the provided datasheet or design your own observation sheets based on your experimental objective. Be sure that the above information is included and that the data display is clear to your instructor.

Figure 1 : Using data from the first week of observation of your Ecoflask, make a graph showing the species

composition of organisms in your Ecoflask (Hint: abundance on y-axis, series of “species” on x-axis).

Figure 2: Calculate species richness for each of your observation days. Species richness is number of different

species in your Ecoflask. Make a graph that shows the change of species richness over time (week 1 to week 2).

Figure 3: Create a graph that shows change over time of your experimentally manipulated variable.

All graphs must include figure captions; specific hypotheses are not necessary. Discussion: Journal questions: Write thoughtful and complete answers to the series of discussion questions on the ecoflask

journal handout. Remember to use good scientific writing, which includes active voice, full sentences, proper

punctuation, and appropriate scientific vocabulary. The journal questions also include an illustration of a nutrient

cycle that is operating within your ecoflask.
