Business Economics Analysis

By Academic Wizard Blog

Business Economics Analysis

Academic essays should begin with an introduction, but do not begin your paper with an “Introduction” heading. The introduction will provide readers with the context necessary for understanding your argument and the body of your paper. When composing the introduction, think about what context or background information the reader would benefit from knowing. Once your context is established, transition from that context into your thesis statement. The thesis statement generally comes at the end of your introduction and usually consists of a few sentences that sum up the argument for your paper overall. Thesis statements should also provide a roadmap for the reader so that they can navigate through the ideas present in the rest of your paper.

Issues to be Solved

Start typing your response to question one. Describe the issues and problems to be solved. Your response should be in your own words to avoid plagiarism. You should use full sentences and double-check for correct grammar, capitalization, and punctuation.

SWOT Analysis

Strengths

Start typing your response to question two. Strengths are internal factors you can control. Your response should be in your own words to avoid plagiarism. Do not use a bulleted list. You should use full sentences and explain each item. Double-check for correct grammar, capitalization, and punctuation.

Weaknesses

Start typing your response. Weaknesses are internal factors you can control. Your response should be in your own words to avoid plagiarism. Do not use a bulleted list. You should use full sentences and explain each item. Double-check for correct grammar, capitalization, and punctuation.

Opportunities

Start typing your response. Threats are potentially positive external factors in the business environment (chapter one) you cannot control. These are things such as technology, competition, the economy, political and legal factors, factors in the social environment, and globalization. Your response should be in your own words to avoid plagiarism. Do not use a bulleted list. You should use full sentences and explain each item. Double-check for correct grammar, capitalization, and punctuation.

Threats

Start typing your response. Threats are potentially negative external factors in the business environment (chapter one) you cannot control. These are things such as technology, competition, the economy, political and legal factors, factors in the social environment, and globalization. Your response should be in your own words to avoid plagiarism. Do not use a bulleted list. You should use full sentences and explain each item. Double-check for correct grammar, capitalization, and punctuation.

Economic Factors

Macroeconomic Factors

Start typing your response. Your response should be in your own words to avoid plagiarism. Do not use a bulleted list. You should use full sentences and explain each item. Double-check for correct grammar, capitalization, and punctuation.

Microeconomic Factors

Action Plan

Conclusion

The last section or paragraph of your paper should be the conclusion. A conclusion should reiterate the major points of your argument. To do this, think about developing your thesis by adding more detail or by retracing the steps of your argument. You can recap major sections for the reader. You can also summarize the primary supporting points or evidence you discussed in the paper. The conclusion should not introduce any new information in order to avoid confusing the reader. To end the paper, think about what you want your reader to do with all the information you just presented. Use the conclusion to establish the significance and importance of your work, motivate others to build on what you have done in this paper, and encourage the reader to explore new ideas or reach other conclusions.

Describe the issues and problems to be solved,
What are the organization’s strengths?,
What are the organization’s weaknesses?,
What opportunities exist in the external environment?,
What threats could negatively affect the organization?

Crisis Decision-Making in Social Work

By Academic Wizard Blog

Crisis Decision-Making in Social Work

Based on your personal experiences, apply the reading from this week to a crisis situation where you, in the role of social worker, needed to make a rapid decision. Share your process for the decision and the outcome. Would you do things differently in hindsight? What advice would you give your supervisees in a similar situation?

Discussions should be approximately 350 words long, use scholarly sources to back statements and arguments, use proper APA formatting for citations and references. (Review the Discussion Participation Scoring Guide to ensure you are responding with distinguished level posts.)

Apply the reading from this week to a crisis situation where you in the role of social worker, needed to make a rapid decision,
Share your process for the decision and the outcome,
Would you do things differently in hindsight?,
What advice would you give your supervisees in a similar situation?,
How do scholarly perspectives support your approach?

Answer:

Crisis intervention requires social workers to make rapid, ethically sound, and evidence-based decisions to ensure client safety and stability. One situation that reflects this occurred when I had to respond to a client experiencing suicidal ideation during a counseling session. Drawing upon Roberts’ (2005) Seven-Stage Crisis Intervention Model, which emphasizes assessment, rapid engagement, and safety planning, I immediately assessed the client’s risk level by asking direct questions about intent and access to means. Recognizing imminent risk, I contacted emergency services while maintaining a calm, empathetic presence to de-escalate the client’s anxiety and fear.

The decision-making process was grounded in both ethical principles and professional judgment. According to the NASW Code of Ethics (2021), social workers are mandated to prioritize client safety and act in their best interest, even when confidentiality must be temporarily breached to prevent harm. The outcome was positive—the client received immediate psychiatric evaluation and was later enrolled in a community support program. Reflecting on this experience, I realized that while my actions were effective, additional debriefing with my supervisor and colleagues afterward could have enhanced my emotional resilience and informed future interventions.

In hindsight, I would implement a structured post-crisis reflection process to evaluate emotional responses and ensure long-term learning. Research suggests that reflective supervision supports professional growth and reduces burnout (Kadushin & Harkness, 2014). For supervisees, I would emphasize the importance of preparation and ethical clarity—understanding crisis protocols, practicing risk assessment, and being familiar with community resources. I would also advise maintaining composure, using empathy as a stabilizing tool, and documenting every step of the intervention for accountability and learning purposes.

Ultimately, crisis decision-making in social work requires balancing urgency with ethical practice, informed by theory, supervision, and reflective learning. The integration of evidence-based frameworks and professional ethics ensures effective and compassionate outcomes for clients in crisis.

Wave Properties & Phenomena

By Academic Wizard Blog

Wave Properties & Phenomena

The three most common types of waves that we encounter in our daily life are water, sound, and light waves. While water and sound waves can only travel through a medium, light waves don’t need one. In this activity, you’ll study the similarities and differences among water, sound, and light waves.

To begin your activity, open this simulation: Wave Interference.

There are three tabs, Water, Sound, and Light. Observe these waves and then draw conclusions from your observations.

Question 1

Water: Start with the Water tab. Note that light areas represent places where the water is high (crests). Dark areas represent low points (troughs).

The water drops should already be dripping from the faucet. You can increase their frequency by using the Frequency slider. You can expand or decrease the size of your “sink space” by clicking the green +/- sign in the upper right corner of the sink. Using the controls on the far right, you can add measuring tools, add a wall, add another faucet, or insert a single-slit or two-slit barrier.

Part A

What kind of wave patterns do you observe in the sink in the top view?

15pxSpace used(includes formatting): 0 / 30000

Part B

Click on the Show Graph button at the bottom of the window. (If you have expanded your sink, you’ll probably need to decrease its size again to see this graph.) The graph shows the moving water level, which is the actual amplitude of the waves.

What general mathematical graph function does this look like? What pattern do you observe in the amplitude of these waves? Provide a hypothesis to explain this pattern in the amplitude.

15pxSpace used(includes formatting): 0 / 30000

Part C

What happens when you increase the frequency of the water drops? What happens to the wavelength of the waves on the surface of water?

15pxSpace used(includes formatting): 0 / 30000

Part D

If you increase the frequency, what happens to the velocity of the wave?

In answering this question, describe how you determined the velocity as well as the result you arrived at. Then, provide a scientific explanation for this result, based on your knowledge of waves.

15pxSpace used(includes formatting): 0 / 30000

Part E

What happens when you add a second drip and space both the drips close together? Describe the pattern they form and explain the cause for this pattern in detail.

15pxSpace used(includes formatting): 0 / 30000

Part F

Turn off the second drip and then add a barrier with one slit. What do you observe on the right side of the wall? What do you observe on the left side of the wall? From a physics perspective, explain your observations of what is happening on both sides of the barrier.

15pxSpace used(includes formatting): 0 / 30000

Question 2

Sound: Now click the Sound tab.

Part A

On the Sound tab, investigate briefly all the phenomena you explored with water waves above and describe any similarities in your results for sound. Specifically, describe

wave pattern as seen on the screen
shape and amplitude of the graph
effect of frequency on wavelength
effect of frequency on velocity
pattern with two sources
wave pattern with a single-slit barrier

15pxSpace used(includes formatting): 0 / 30000

Part B

Sound and water waves obviously have many similarities, but they are not exactly the same. Describe all the differences you can think of between sound waves and water waves.

15pxSpace used(includes formatting): 0 / 30000

Question 3

Light: Now click the Light tab.

Part A

On the Light tab, once again investigate briefly all the phenomena you explored with water and sound above. Describe any similarities in your results for light. Specifically describe

wave pattern as seen on the screen
shape and amplitude of the graph
effect of frequency on wavelength
effect of frequency on velocity
pattern with two sources
wave pattern with a single-slit barrier

15pxSpace used(includes formatting): 0 / 30000

Part B

Light waves have some similarities with water and sound waves, but they are not exactly the same. Describe all the differences you can think of between light waves, sound waves, or water waves.

Electricity, Fields & DNA

By Academic Wizard Blog

Electricity, Fields & DNA

discussion- An enormous amount of electricity is created at power-generating stations and sent across the country through wires that carry high voltages. Appliances, power lines, airport and military radars, substations, transformers, computers, and other equipment that carries or uses electricity all generate electromagnetic fields.

Many questions have been raised about how electromagnetic fields affect our bodies. Do they pose a public health risk? Perform an Internet search to find information about the effects of electromagnetic fields on public health. Then, discuss the pros and cons of using equipment that produces an electromagnetic field.

Here is one authoritative source to get you started: electromagnetic fields and public health.

Double Helix Structure of DNA

This task connects the physics of electrostatics with molecular biology. Molecular biology is the study of the structure and function of the cell at the molecular level. DNA’s double helix structure consists of two strands held together by electrostatic forces. Do online research on electrostatics and molecular biology, and then answer the following questions. Here are two sources to start with:

Part A

What is DNA and what is its role in life? List DNA’s four nucleotide bases.

Electric Field of Dreams

In this activity, you will explore the relationship between the strength and direction of the electric field lines to the type of charge on a particle and its magnitude. You will also explore the interactions between two or more charged particles and observe their movement. To begin your activity, open the simulation: Electric Field of Dreams. ‪‪Electric field of dreams‬ 1.0.0-dev.10‬

Directions:
At any time you may

click the Reset All button to reset all the settings;
click the Play/Pause button to pause or resume the motion; or
pause the motion and then click the Step button to observe the motion step-by-step.

Part A

To begin, click the Add button to add one object to the system. Observe the electric field around this charged object. You may move the object around the field by dragging it with your cursor. While the arrows indicate the direction of the electric field around the charge, the length of the arrows indicates the field strength. Based on your observations of the field, what is the charge on this object? Give your reasoning.

15pxSpace used(includes formatting): 0 / 30000

Part B

Set the charged object in motion by dragging it and releasing it. What do you observe about the behavior of the field lines in the vicinity of the object?

15pxSpace used(includes formatting): 0 / 30000

Part C

Add another charged object to the electric field by clicking the Add button again. What is the charge of this new object? Give your reasoning. What do you observe about the behavior of both the objects as well as the field lines in the vicinity of both the objects?

15pxSpace used(includes formatting): 0 / 30000

Part D Electricity, Fields & DNA

Click the Remove button to remove one of these objects, and then click the Properties button to set properties for the next object you will add. Just change the sign of the charge to (+), then click Done. Click Add to add this new object to the field. Now what do you observe about the behavior of the two objects and the field lines that surround them?

15pxSpace used(includes formatting): 0 / 30000

Part E

With the two oppositely-charged objects still in the field, apply an external field to the system: In the External Field box, simply drag the dot until it becomes an electric field vector in some direction. Observe, describe, and explain the behavior of the two objects.

15pxSpace used(includes formatting): 0 / 30000

Electric Field Hockey ‪‪Electric field hockey‬ 1.0.0-dev.10‬

In this activity, you will again explore the relationship between an electric field and charged particles in the field, but this time you’ll have a gaming challenge. To begin, open Electric Field Hockey.

Directions:
On the control bar, make sure that the Puck is Positive and the Field boxes are checked. Also, make sure that the Practice option is selected.

Your aim is to score goals by manipulating the black puck (test charge) into the blue-colored bracket (goal) on the right. Think smart and place positive source charges (red) and negative source charges (blue) in such a way that the black puck moves into the goal.

Note that when you place a red, positive source charge in the hockey field, a red arrow appears on the black puck (test charge) showing the force the positive charge exerts on the puck. Similarly, when you place a blue, negative source charge in the hockey field, a blue arrow appears on the black puck (test charge) showing the force the negative charge exerts on the puck.

Part A

Place a red charge in the hockey field and click Start. In which direction do electric field lines point? In which direction does the black puck move? What conclusion do you draw from this movement?

15pxSpace used(includes formatting): 0 / 30000

Part B

Click Reset and then click Clear. Now, place a blue charge in the hockey field and click Start. In which direction do electric field lines point? In which direction does the black puck move? What conclusion do you draw from this movement?

15pxSpace used(includes formatting): 0 / 30000

Part C

Manipulate the mass of the puck by dragging the Mass bar to the right for increasing the mass and to the left for decreasing it. What changes do you see in the speed of the puck? Which principle works behind this change?

15pxSpace used(includes formatting): 0 / 30000

Part D

In the same situation, what do you observe about the relationship between the speed of the black puck and its distance from the blue charge?

15pxSpace used(includes formatting): 0 / 30000

Part E

You can make the puck travel in complex ways by placing a set of charges around on the field. So, here’s your game challenge: Arrange source charges around to propel the puck from its starting position into the goal. That’s pretty easy for a straight shot; you just put a negative charge behind the goal. But what if there are barriers in the way? That’s a real test of your physics understanding, including Newton’s laws of motion and electrostatic forces. Game’s on!

On the control bar, check the Trace, Field, and Anti-alias boxes. The game has three Difficulty levels. Start with Difficulty level one and arrange source charges to get the puck into the goal. Once you’ve made a score at any level, increase the Difficulty level. Take a screen capture of two of your most difficult goals and paste them here. At least one of these should be at Difficulty level 2 or 3.

(Note: On a Windows computer, you can use the key combination Alt-Print Screen to copy the currently-active window to your clipboard. When you capture an image of this simulation window, paste the image into an image-processing program such as Paint, and save the image as a file. Then use the Insert Image button to insert the file into the response area.)

Do electromagnetic fields pose a public health risk?,
What are the pros and cons of using equipment that produces an electromagnetic field?,
What is DNA and what is its role in life? List DNA’s four nucleotide bases.,
Explain DNA’s structure specifically noting the role electric fields and forces play in it.,
Based on your electric field simulation what do you observe about the charge behavior and electric field direction?

Home Electricity Use & Conservation

By Academic Wizard Blog

Home Electricity Use & Conservation

Discussion- It’s possible to save a great deal of electrical energy (and money and natural resources) with some simple changes in household electrical use. The trouble is that most of these changes mean either changing behavior or spending money. Do an Internet search and review a few ways to save electrical energy. Discuss at least one change that you think would be reasonable and worthwhile to do in your own home in the next year. Provide your rationale.

Home Energy Use

In this activity, you are going to perform an experiment to track the amount of power you and your family use, then look at some basic patterns in that usage. (NOTE: If you live in an apartment or home in which you do not have access to the electrical meter, consult with your instructor about alternative arrangements, like teaming with a classmate to gather this data.)

This experiment is going to span the course of a full week and require 12 meter readings. It really involves two separate experiments:

tracking daily energy use for a week to compare any usage variations from day to day
comparing a single high-usage time period of a few hours with a single low-usage time period of a few hours to help you identify the extremes in your household electrical use

You can easily do both experiments during the same time period. This approach would be the easiest and fastest way to proceed. Read the instructions for both Part A and Part B if you wish to do both experiments at the same time.

To begin, you’ll need to find your electric meter, which could be inside or outside of your home. Many electric meters these days are digital and pretty easy to read, but if you have an older “dial-type” meter, go to this electric meter reading guide to learn about how to read and understand it.

For each of the two experiments below, you will first record three simple pieces of data in a table:

1) day and date, 2) time, and 3) the kWh reading from the meter.

Then record the results of three simple calculations:

kWh used: Calculate kWh used since the last reading (subtraction).
Hours elapsed: Calculate the number of hours since the last reading (subtraction rounded to a whole number).
Average kW used: (kWh used)/(hours elapsed). If this number turns out to be 0.36, for example, it means that your average household power usage for the time period was about 360 watts, the equivalent of running six 60-watt bulbs for that whole time period.

Part A

Daily Electrical Usage: Data Collection

Pick a convenient time of day to take readings from your electric meter. You’ll need readings roughly a day apart, but if they differ by only an hour or two, that should be fine. Pick a consistent time you’ll remember, though, such as after getting home for the day. You need to start by doing an initial meter reading, then follow up with a reading every day for the next 7 days. You’ll do 8 readings in all.

Record your readings in the tables below. In addition to the data fields described above, there is a lot of room for usage notes. Record anything that might have substantially affected the electrical usage since your previous reading. This might include the amount of time people were around and awake at home, use of specific devices such as an air conditioner, clothes dryer, TV, or lighting.

Part B

Usage Extremes: Data Collection

For this experiment, you’ll measure electrical usage during a time period when you expect to have very light electrical usage (for instance, while you’re asleep at night or during the day when no one is at home). Likewise you’ll measure electrical usage during a time period when you expect to have heavier than average electrical usage. This time period might be in the evening, when lights and other appliances are on. Both of these time periods should be at least 4 hours long, to increase the accuracy of your results.

Record your results in the tables below for each situation. For each time period, you’ll need to take an initial and a final reading.

Part C

Let’s start the analysis by looking at your “extreme usage” cases. Compare the two cases in detail—low usage period versus high usage period. Discuss differences between the two as well as any surprises. Things you should cover in your discussion: How much difference was there in average power usage (avg. kW) between the low-usage and high-usage time periods? What might have been running during the low-usage period that used energy? Identify likely “stealth” energy users that you could not turn off during the low-usage period. What do you suppose contributed most to the usage during the high-usage period?

15pxSpace used(includes formatting): 0 / 30000

Part D

Having looked at your “extreme usage” cases, analyze your day-to-day usage. Discuss in detail. Specifically, compare higher usage days to lower usage days. Were there significant variations? Do your conclusions regarding the “extreme” cases help to explain any daily variations? What were the surprises or new insights you had in reviewing this day-to-day usage record?

15pxSpace used(includes formatting): 0 / 30000

Part E

It is possible to save a great deal of electrical energy (and money and natural resources) with some simple changes. You’re probably familiar with what some of those changes are and are now more attuned to your own electrical usage. The trouble is, most of these changes either mean changing behavior or spending money. Search the Web for a few ways to save electrical energy. Record them below and categorize them, if possible, as “change behavior” or “spend money.” You might want to consider adding a “neither” category. There are a few things that don’t really require much change or money at all. Include your sources in your answer.

Which times of the year are best for seeing the northern lights, and where are the best places to view them? Explain your answers. Also identify links to good images. If you’ve ever seen the aurora borealis, describe your experience and note the time and place that you saw it.

Faraday’s Law

Electric generators use the properties of electromagnetism to transform kinetic energy into electrical energy. Many electric generators work by spinning a permanent magnet near coils of wire. Experiment with this simulation of electricity generation to visualize how this process works. Once the simulation opens, try moving the permanent magnet around to see what happens. Also rapidly switch the polarity of the magnet by repeatedly clicking on the magnet icon at the bottom of the page, and observe the effect.

Part A

Try moving the magnet in the different ways described in the table below,. Record your observations in the second column of the table.

Motion Observations

Move the magnet straight through the coil, leading with the north pole. Once the magnet is completely through, move it back to its original position.

Move the magnet straight through the coil, only this time leading with the south pole. Once the magnet is completely through, move it back to its original position

Put the magnet in the center of the coil, but don’t move it.

Put the magnet on the outside of the coil. Repeatedly move it up and down while outside of the coil.

Keeping the magnet outside of the coil. Repeatedly move it back and forth horizontally.

Place the magnet back inside of the coil. Now repeatedly switch the polarity of the magnet by pressing the button toward the bottom-right of the page over and over again.

Nuclear Reactions & Energy

Scientists such as Heinrich Hertz, Philipp Lenard, Max Planck, and Albert Einstein made scientific contributions that ultimately demonstrated that light is electromagnetic radiation, and that it has a “dual nature.” Some electromagnetic phenomena are best explained with a particle model, and some with a wave model. In a sense, “wave” and “particle” are just easy mental models for light. We employ them because we are used to seeing waves and particles—such as those in water waves and baseballs—in our daily lives. Electromagnetic radiation is a basic concept in physics, but it doesn’t fit completely into one of these neat little boxes.

Research and discuss at least one modern technology that employs electromagnetic radiation and that can be explained by the wave model, the particle model, or a combination of the two. Some possible technologies include solar panels, burglar alarms, cameras, and cell phones.

Online Physics Lab Report Guidelines

By Academic Wizard Blog

Online Physics Lab Report Guidelines

• Laboratory Preparation: Instructions to all lab experiments are posted on our Blackboard course website. Before performing each lab activity, students must read the instructions, prepare for the laboratory, and study the theory for the experiment. Online lab experiments will be performed by each student as specified in the lab instructions, and a single report will be submitted for each experiment activity. Students can work on the experiments individually or in small groups of 2 or 3 students, but each student must write and submit their own lab report and include a detailed list of contributions from all group members to the lab (see below).

• Laboratory Report Policy: Each lab experiment will span two weeks: The 1st week is devoted to reviewing the activity and collecting the data, while the 2nd week is devoted to completing the lab report. Each student will be responsible for producing a report pertaining to each experiment. Lab reports must be typed and submitted (uploaded as assignments) via Blackboard website using the corresponding link available in the Labs & Reports folder. Lab reports are due on Sunday by midnight (11:59 pm) before your next lab (see course schedule). Lab reports will be graded and returned to you via Blackboard website with feedback and comments. Reports will not be accepted via email. A student must pass the lab portion of the course in order to pass the entire course.

• Late Report Policy: Late laboratory reports will only be accepted in the case of extreme emergency or illness and prior arrangements have been made with the instructor. Students that do not participate in the lab activity or do not submit the required lab report, will not get credit for the lab and will receive a grade of zero (0%). Refer to the course syllabus for more details.

• Format of Laboratory Reports: Laboratory reports must be typed professionally using Microsoft Word (*.doc or *.docx) and in standard font. Plagiarism and copying from the lab instructions or from another student will not be tolerated. Each report must be a single document less than 1 MB in size, and the basic parts of all lab reports must be arranged in the following order:

1. A “Title page” containing your name followed by your partner’s names if any, the title of the report, the

course code, section number, and the date when the experiment was performed.

2. A section entitled “Objectives”, which contains the objective or objectives of the experiment.

3. A section entitled “Theory”, which contains all pertinent theoretical considerations and equations used during the lab or in the calculations. All equations must be explained and typed using Microsoft Word.

4. A section entitled “Equipment and Materials”, which contains a list of the equipment and materials used to carry out the experiment. Also, include a sketch of the lab set-up, equipment, or simulation.

5. A section entitled “Data”, which contains the collected data and results in tabular format. All data tables must be typed using Microsoft Word. Do not include any calculations in this section.

6. A section entitled “Graphs and Screenshots”, which contains any required graphs, diagrams, or screenshots. All graphs must have a title, a well-chosen scale, and properly labeled axes. Curves and straight lines should be drawn smoothly and as close to as many points as possible. Graphs must also display any required slopes or intercepts. Screenshots must be clear and properly labeled.

7. A section entitled “Calculations”, which contains detailed calculations for all trials showing the equations used, algebra, and results rounded to the correct number of significant figures. Include in this section comparisons with expected or standard values (percent error or percent difference). All calculations must be typed using Microsoft Word.

8. A section entitled “Conclusions”, which contains conclusions based on the data, calculations, physical theory, and lab analysis. The conclusions should include: ✓ Summary of final results (values). ✓ Comment on the agreement or disagreement of the results with the theory or expectations. ✓ Answers all analysis questions given in the lab instruction or by the lab instructor. ✓ Discuss what you personally learned from this experiment and your observations/comments. Online Physics Lab Report Guidelines

9. A section entitled “Sources of Error”, which contains a list of the possible sources of experimental errors. There are always errors in any measurement. Identify some of the significant sources.

10. A section entitled “References” that lists all references used. Textbook and lab manual/handouts should always be included.

11. If students worked on the lab as a group, include a section at the end of the report entitled “Contributions” that lists in detail the contributions of all group members to the lab. Remember that each student must write and submit their own lab report for each lab activity or experiment.
