Adaptability

Skill #9: Lead and Plan for change by developing a process to manage change and using it to lead change events.

Dwight and Ike have had many conversations lately about their vision and core values for the business in light of their plans for expansion. One troubling issue they finally came to a decision on was their policy upon only hiring America wounded veterans. While both owners really want to keep up this tradition, they came to an understanding that going abroad would mean it would be harder to honor the tradition but also may make some veterans unhappy with their choices of places to expand (e.g. Viet Nam). It also seemed to them that they were limiting their employee pool and not really encouraging customer support by not hiring any person with a disability who was qualified for the jobs they offer. After all who better to understand the needs of a person who needs the use of a wheelchair than someone else who uses one? They also wondered if they should give first preference to American veterans. Still undecided on this point, Dwight and Ike want to see how good you are at leading change. They have not released their decision on this policy change. This change is important to the happiness of those employees in the company. They are proud to be a member of the staff of EC and think of the company as a way to again serve their country. Dwight and Ike want you to create a plan that will make the policy change run smoothly in this instance and in others going forward. The plan should include:

Directions: 

  1. By FRIDAY, complete the following:
    • Create a change plan. This includes any steps you deem Dwight and Ike should take to clarify the policy.
    • The steps, order, and ways to implement the policy change should be detailed. Consider designing the headings for the steps etc. that you are making a template for change implementation. These choices should be designed to fit any change effort that the company or you face in the future. Make sure to include the major components needed to effect change.
    • An explanation/justification as to why the steps, the order and ways of implementation were chosen should be discussed.
    • A discussion as to why the steps will be successful in creating the desired change.
    • You must use course material to support your responses and APA in-text citations with a reference list.

Describing a Larger Conversation

  

GOAL The goal of this essay is to accurately describe a complex issue based on two (2) texts that address one or more parts of the issue. Your goal as a writer is to inform your reader. 

TOPIC Don’t Blame the Eater by David Zinczenk

DIRECTIONS Choose to one (1) article from TS/IS, find another article on the same topic. It must be a thesis-driven article from a reputable source (so Wikipedia and other reference texts are out). Explain the different perspectives on the issue. Rather than presenting the issue as having only two sides (for or against), show and explain the complexity of the issue using the two (2) texts you’ve chosen. You will not respond to this issue – all of the views you present must come from the two (2) texts you choose.

FORMAT The essay should be 4-5 full pages, typed and double spaced, and include a works cited page. The MLA-style works cited page should include the essay from the TS/IS you have chosen and the essay you found for a total of two (2) essays. Your essay must include at least four quotations, which must be correctly formatted using MLA-style parenthetical citation for the page numbers, and at least four templates, including at least one to introduce a quotation (see p. 46) and one to explain a quotation (see p. 47).

AUDIENCE As you write each part of your essay, assume that your audience (me and your classmates) may not be completely familiar with the essays you have chosen. 

Assignment: Models of Grieving

 

The death of a loved one is a significant event that everyone experiences. An individual’s social environment, including societal and familial cultural factors, may influence how an individual approaches death or grieves the loss of someone else who dies. You can anticipate addressing grief in your social work practice and, therefore, should develop an understanding of the grieving process.

Two models of grieving—the Kubler-Ross and Westburg models—identify stages through which an individual progresses in response to the death of a loved one. Understanding the various ways individuals cope with grief helps you to anticipate their responses and to assist them in managing their grief. Select one model of grieving—the Kubler-Ross or Westburg model—to address in this assignment.

Addressing the needs of grieving family members can diminish your personal emotional, mental, and physical resources. In addition to developing strategies to assist grieving individuals in crisis, you must develop strategies that support self-care.

In this Assignment, you apply a grieving model to work with families in a hospice environment and suggest strategies for self-care.

By Day 7

Submit a 2- to 4-page paper in which you:

  • Explain how you, as a social worker, might apply the grieving model you selected to your work with families in a hospice environment.
  • Identify components of the grieving model that you think might be difficult to apply to your social work practice. Explain why you anticipate these challenges.
  • Identify strategies you might use for your own self care as a social worker dealing with grief counseling. Explain why these strategies might be effective.

Support your Assignment with specific references to the resources. Be sure to provide full APA citations for your references.

Consulting for the Caring Angel Hospital

Overview

Imagine that you are a senior consultant at Practical Health Care Consulting. Your supervisor has instructed you to spend three months at the Caring Angel Hospital to help improve the quality of care, add value to the organization, improve employee morale, design an efficient organizational chart, create a strong team environment, and create the hospital’s competitive advantage. The hospital has traditionally made losses year after year. Furthermore, it is not performing well financially, and the banks are not willing to lend it large sums of money for more effective marketing.

After spending two months within the hospital, you are very happy with your progress, and you think you are capable of acquiring more patient base and expanding the hospital market. However, with a closer look, you notice that your patients are still hopping from one specialized hospital to another in search of various specialized treatments. You also notice that the seats are not comfortable in the waiting area, and the patients continuously show up for appointments on the wrong dates. The nurses and the employees are not smiling during patient conversations, and everyone looks for ways to blame others for failures in the patient treatment process. Everyone seems to work alone and hide what they do from their colleagues.

At the end of the 3-month period, you must provide a report with your recommended strategies designed to help Caring Angel Hospital achieve its goals.

Note: You may create or make all necessary assumptions needed for the completion of this assignment.

Requirements

Write a 4–6 page paper in which you:

  • From a consulting perspective, propose the major steps that Caring Angel Hospital could take to achieve each of the following goals:
    • Improve the quality of care.
    • Add value to the organization.
    • Improve employee morale.
    • Design an efficient organizational chart.
    • Create a strong team environment.
    • Create the hospital’s competitive edge.
  • Recommend one approach that the hospital could use for acquiring a larger market share given the prevailing financial circumstances. Justify your recommendation.
  • Investigate at least two value-added services that Caring Angel Hospital could offer to strengthen its value proposition. Provide at least two examples of the advantages of these value-added services to the hospital.
  • Go to Basic Search: Strayer University Online Library to find four recent (within the last five years) quality academic resources for this assignment. Note: Wikipedia and other websites do not qualify as quality academic resources.

This course requires the use of Strayer Writing Standards. For assistance and information, please refer to the Strayer Writing Standards link in the left-hand menu of your course. Check with your professor for any additional instructions.

The specific course learning outcome associated with this assignment is:

  • Propose a plan to improve the operations, working environment, competitive edge, and value-added services of a hospital.

Do not use your previous papers as source for your final paper, they must be fresh new material. Ideas and rationales can be used since it does build upon concepts from the previous weeks/papers. If you cut and paste from your previous papers to simply make up your final paper it will be a tier 2 violation with 50% credit.

When epidemiologists are working to track a disease, the three elements that they focus on are the agent, the host, and the environment. Following are explanations of each element.

 

When epidemiologists are working to track a disease, the three elements that they focus on are the agent, the host, and the environment. Following are explanations of each element.

The agent is what causes the disease. The agent is often a virus or bacteria but can also be caused by other agents. In the scenario, described in the Introduction, the agent is the E.coli bacteria. 

The host refers to those who are contracting the disease. The host doesn’t necessarily become sick. Hosts can serve as carriers of the disease who do not show outward signs or symptoms. 

Finally, the environment refers to the external factors that support or cause the disease to spread. In the E. coli scenario, the lettuce became infected either at the farm or during transport; the lettuce was sold to the distributor and then to Sam’s Sandwich trucks; and people ate the lettuce on these sandwiches.

Each of these steps is important to tracking the disease, and epidemiologists work diligently to trace and report each of the steps to prevent further transmission of the disease.

The following is an example of an epidemiologic triad.

  • Agent: Salmonella bacteria
    • Keep in mind that agents can be biologic (e.g., bacteria or viruses), chemical (e.g., poisons or alcohol), physical (e.g., trauma or radiation), or nutritional (e.g., a lack or excess of essential nutrients).
  • Host factors: Individuals who are particularly vulnerable (e.g., the very young or very old and immunocompromised individuals).
    • Note that, in general, host characteristics can include age, sex, race, religion, customs, occupation, genetic factors, other health factors, and immunologic status.
  • Environmental factors: Contaminated kitchen surfaces or utensils, undercooking of contaminated food items, or contaminated chicken.
    • Environmental factors can include temperature, crowding, noise, pollution, food, and radiation.

Changes in one factor in the epidemiological triad can influence the occurrence of disease by increasing or decreasing a person’s risk for disease. Consider how variations in each factor, shown in the example, can influence the manifestation of disease. Refer to pages 435-440 in your Friis and Sellers (2021) textbook for further explanation.

In this Discussion, you will apply the epidemiologic triad to a disease of your choice to gain a better understanding of both the model and the disease. 

To prepare  for this Discussion: 

Access and review the Epidemiological Triad Learning Interaction.

Select an infectious disease from the list proved in List of Infectious Diseases document for Week 1 Discussion. 

Review the Week 1 “Ebola Virus Disease in the Light of Epidemiological Triad” (Kaur, Sachdeva, Jha, & Sulania, 2017) resource. Consider how the epidemiologic triad/triangle can be applied to your selected disease.

Consider how variations in each factor shown in the example from the textbook can influence the manifestation of the disease. Refer to pages 435-440, in your textbook, for further explanation.

By Day 4

Post a comprehensive explanation of the following:  

  • Identify  ebola virus disease Following are explanations of each element. 
  • Provide an example of an agent that is associated with the infectious disease that you selected. 
  • Discuss  at least three  examples of environmental factors that contribute to the likelihood of transmission of the agent to an individual for the disease you have selected. 
  • Discuss at least three  examples of host factors that contribute to the likelihood of transmission of the agent to an individual for the disease you have selected.

Galaxies and the Expanding Universe

Materials Required:

  • Computer and internet access
  • Calculator
  • Pen/pencil
  • Digital camera or scanner
  • Download and print the Hubble Diagram Sheet (as an additional option, you can create your graph with the Excel program or create your own graph by hand)

Total Time Required: Approximately 2-3 Hours

Part 1. The Doppler Effect

Note: For your lab report, only include your clearly labeled answers to the below questions in all parts. Copy/paste in your photos or diagrams when needed.

Among the great achievements of Einstein was his understanding of the speed of light. The speed of light, in a vacuum, is a constant at ~ 300,000 kilometers/second (the actual velocity is 299,792.458 km/s). The speed of light is essential to the viability of both Einstein’s  theories of Special and General Relativity (since the speed of light is a constant it has been given its own mathematical symbol, c). If the speed of light is not constant than neither of Einstein’s theories are credible and would not be accurate in describing physics at the larger-scales of the Universe and objects moving at high velocities close to the speed of light.

Therefore, since the speed of light is a constant any motion by an object emitting light has no effect on the lights velocity nor does an object seeing light from a source moving towards it measure any change in the speed of the light coming towards it.  For example, a car is driving at night with its headlights on at a speed of 75 miles per hour. What is the speed of the light coming from the headlights? Common sense would give its speed as the speed of light plus 75 miles per hour (c + 75) but the measured speed is still the speed of light ( c ). Something had to change in this situation however and in in this part of the lab you will be investigating the change that is occurring here which is known as the Doppler Effect. 

Use this link to the Doppler Shift Demonstrator Animation. Click on the ‘Help’ button for instructions on how to run the animation. (Below is a screenshot of the Doppler Shift Demonstrator). 

Screen shot of Doppler Shift Demonstrator

Click and move the emitting source towards the middle, left side of the screen and click and move the observer to the opposite side. You can control the frequency of the emitted wave with the rate slider bar and can move either the source or object by left-clicking, holding, and dragging the object towards the direction you want it to move. Answer the following questions based on the simulations being viewed.

  1. With the emitting source and the observer on the opposite side of the screen press the ‘start emission’ button.  Record your observations of the wave and its wavelength as seen by both the emitting source and the observer (be as detailed as possible).
  2. Now click, hold, and drag the observer so it is moving to the left, towards the emitting source. Record your observations of the wave and its wavelength as seen by both the emitting source and the observer (try to make the motion as uniform as possible).
  3. Reverse directions and click, hold, and drag the observer so it is moving to the right away from the emitting source.  Record your observations of the wave and its wavelength as seen by both the emitting source and the observer.

For the next set of questions we’ll do the opposite and move the emitting source (i.e. a star, a galaxy, a quasar) and keep the observer stationary (i.e. the Earth).

  1. Click, hold, and drag the emitting source so it is moving towards the observer. Record your observations of the wave as it moves in the same direction of the moving source and the wave as it moves in the opposite the direction of the moving source. Also, describe the wavelength as seen by the observer.
  2. This effect on wavelength, as seen by the observer, is known as blueshift. Consult your textbook or other source and explain in your own words using 1 to 2 sentences what is blueshift? (cite all sources in proper APA citation)
  3. Click, hold, and drag the emitting source so it is moving away from the observer. Record your observations of the wave as it moves in the same direction of the moving source and  the wave as it moves in the opposite the direction of  the moving source. Also, describe the wavelength as seen by the observer.
  4. This effect on wavelength, as seen by the observer, is known as redshift. Consult your textbook or other source and explain in your own words using 1 to 2 sentences what is redshift? (cite all sources in proper APA citation)
  5. The fact that only a few nearby galaxies within our own local group of galaxies show blueshift while all far away galaxies are redshifted is seen as evidence for the Big Bang. In your own words, explain why this is seen as good evidence. (cite all sources in proper APA citation)

Part 2. Cosmological Redshift and the Expansion of the Universe

The Big Bang Theory says that the Universe began from a singularity and has expanded over time. Evidence indicates that this is an accelerated expansion meaning that objects are moving faster in the expansion at greater distances. This is what astronomers term as Cosmological Redshift where the redshifts of objects are greater for increasing distances. In this part we will be using the redshift measurements of galaxy clusters (since galaxy clusters are large and very bright they can be seen at very large distances).

The galaxy cluster closest to our own Local Group can be seen (with a telescope) in the direction of the constellation Virgo. We call this cluster the Virgo cluster; it is approximately 50 million light years (15 million parsecs) away. Many even more distant clusters have been found in other directions. They all contain some very large elliptical galaxies, and many smaller galaxies.

On the following page are pictures showing what an elliptical galaxy would look like if it were located in different galaxy clusters. The farther away the cluster, the smaller the galaxy looks. There is an inverse relationship between apparent size and distance. Next to each galaxy, there is a spectrum  of a bright star in the galaxy. The dark lines are “Balmer” hydrogen absorption lines. These lines are not always found at the same wavelength; they are “shifted.” However, the general pattern that the hydrogen lines form in each spectrum always stays the same. That is how we can tell if a certain line is a hydrogen line, even though it is not always found at the same wavelength. The “shift” of the pattern is the Doppler Effect, and it is caused by the motion (relative to us, the observers) of the star that is emitting the light as seen in Part 1 of this lab.

Copy and paste the below 4 objects (Virgo Cluster, etc.) with their corresponding spectra into your lab report. When the wavelengths of hydrogen lines are measured in a laboratory, using a stationary hydrogen lamp, each line is always found at the same wavelength. We call this wavelength the “rest wavelength” and denote it by rest. For your reference: The rest wavelengths of the hydrogen lines (from right to left) are:

Hα (H−alpha)          λrest = 656 nm           [1 nm =10−9 meter]Hα (H-alpha)          λrest = 656 nm           1 nm =10-9 meter

Hβ (H−beta)         λrest=486 nmHγ (H−gamma)   λrest =434 nmHδ (H−delta)       λrest=410 nmHβ (H-beta)         λrest=486 nmHγ (H-gamma)   λrest =434 nmHδ (H-delta)       λrest=410 nm

1.In your lab report under the copied image of the 4 objects, for each corresponding object (label a heading in your report Virgo Cluster through the Bootes Cluster and under each heading you’ll have information for questions #1 – #4, also labeled.) For #1, type out the numbers you estimate for each Balmer hydrogen line (H-alpha, H-beta, etc.) in each galaxy spectra given (match the line pattern as it is labeled on the spectrum of the Virgo cluster galaxy). So for example: Virgo Cluster # 1: H-alpha = 660nm, H-beta = xxx, etc. doing the same for each line and for each object.

virgo and ursa major cluster

corona borealis cluster and bootes cluster

The Doppler Effect does not only affect light, but occurs with waves of all kinds. A familiar example is the change in pitch of the sound from a car as it moves towards you, passes you and moves away from you. As the car moves towards you, the sound waves that move past you are more closely spaced than normal, their wavelength is shortened. As the car moves away, the sound waves move past you with longer spacing than normal, their wavelength is increased. Since a high-pitched sound has a short wavelength, and a low-pitched sound has a long wavelength, we can actually hear the Doppler effect.

This is analogous to what happens to light from a moving source. If a star is moving towards us, its light will have a shorter wavelength, the light is blue-shifted. If the star is moving away from us, the wavelength of the light is longer,  the light is red-shifted. It is easiest to detect the change in wavelength of the light from the shift of the spectral lines. (The shift of the line is the difference between the observed wavelength and the rest wavelength.

2. For each of the 4 objects in your #1 question, now compare the rest wavelength and the observed wavelength of the hydrogen lines. For example: for the Virgo Cluster we found H-alpha = 660nm. The rest wavelength is 656nm. Therefore, the wavelength is different by ____?(you would show this calculation and for the others). Which wavelength is longer? Are the galaxies moving towards us or away from us? (State this for each one.)

The shift of the line gets larger as the speed of the light source (relative to us) increases. There is a formula that makes it possible to determine how fast a source is moving by measuring the change in wavelength.

Doppler Formula:(λobs−λrest)λrest=vcDoppler Formula:λobs-λrestλrest=vc

where:

          A light wave travels at the speed of light, which is 3000,00 km/sec.

3.Use the Doppler formula to determine the speeds of the galaxies. (perform your calculations for just one of the four Balmer lines,show your work for all calculations

4.Compare the distances to the galaxies and the speeds with which the galaxies are moving away from us, and describe their relationship to Earth.

Part 3. The Age of the Universe

Use the ‘Hubble Diagram’ sheet linked at the start of the lab, or create a graph using Excel, or by hand to go into your report (if using the last two options the Hubble Diagram can be viewed as help in scaling your graph) plot your calculated data. 

For each galaxy, plot the recession velocity (y-axis) versus the given distance (x-axis). Draw one straight line which best fits the four data points you have plotted. (line of best fit must go through the (0,0) point on your graph)  On your graph calculate and label the slope of this “best-fit” line? (slope = rise / run) 

You have just done the same calculations that the astronomer Edwin Hubble did in the late 1920’s. The relation you described between the distances and speeds of galaxies is called Hubble’s Law, and the slope of the line is known as the Hubble Constant, HO. 

What does Hubble’s Law tell us about the Universe? At first it may seem as if we (in the Milky Way) are in a “privileged position” in the Universe, since all other galaxies are moving away from us. Are we at the center of the Universe?? We will perform a “thought experiment” to find the answer.

Copy the below images into your lab report.

Imagine that A, B, C, D, and E are galaxies. The arrows represent the speeds of the galaxies as seen from A (longer arrow = higher speed). This diagram represents what Hubble’s Law states.

Galaxies seen from galaxy A

   1. Change your perspective again and do the same for an observer sitting in Galaxy E.

Galaxies is as seen from Galaxy E

   2.Describe what would an observer sitting in galaxy C would see when they looked at the other galaxies? Also, draw      arrows for each of the other galaxies to represent the speeds that this observer would measure. (this can be done in Word by inserting an arrow, or by hand)

Galaxies as seen from galaxy c

  1. Look at the diagrams in questions 1. and 2. What relation will observers in galaxies C and E find between speeds and distances of galaxies? Is the Hubble law the same for observers in all galaxies?

What you have seen in this thought experiment is precisely the explanation of why the proportionality between galaxy distances and speeds leads to the deduction that the Universe is expanding. All galaxies are getting farther and farther apart all the time! 

It is also possible to make an estimation of how long the expansion has been going on; this is the time which astronomers take as the “Age of the Universe,” or the time since the Universe began to expand. The Hubble constant you calculated is the expansion rate of the universe going forward in time while the inverseof the Hubble constant, 1/HO, will take you backwards in time to the origin of the Big Bang. 

How to calculate the age of the universe using Hubble’s constant:

(show your work for all calculations)

  1. First, find the inverse of your value of HO.

            HO = ____________________           1/HO = ____________________

  1. Multiply 1/HO by 3.09 x 1019 km/Mpc to cancel the distance units.
  2. Since you now have the age of the Universe in seconds, divide this number by the number of seconds in a year, 3.16 x 107 sec/yr.                                                                                                                                                                                                                                                                                                                                  (The latest Measurements of the age of the universe, as determined by the Planck satellite, is 13.82 billion years (or 1.382 x 1010). Let’s calculate how close  your measurements came to this Planck age!)                                                        
  3.  Calculate the percentage difference with this formula:
    (Age (planck) – Age (measured) / Age (planck)) x 100 =
  4. In a paragraph (50 word minimum) describe, in your own words, the relationship you have seen in this lab between the expansion of the Universe and the determination of the age of the universe.

Discussion: Evoking Change Talk

 

Change talk is language that reflects movement towards change. There are two broad types of change talk: preparatory and mobilizing. Preparatory change talk occurs when the service user is thinking about changing or exploring a specific change. Mobilizing change talk occurs when the service user is ready to commit to change.

Apply strategies for evoking change talk from the service user in the case study you were assigned in Week 2. You will also consider whether you would evoke preparatory or mobilizing change talk with the service user. As you do so, keep in mind that evoking mobilizing change talk (i.e., commitment to change) before the service user is ready can backfire. 

To Prepare

  • Reflect on the service user’s presenting challenge.
  • Based on the service user and their presenting challenge, identify three strategies for evoking change talk you would use. Then, consider whether you would use preparatory or mobilizing change talk with the service user.

Based on your Hart City service user and their presenting challenge, post a description of three strategies for evoking change talk you would use. Explain why you believe each is the correct strategy to use with your particular service user and their presenting challenge. Then, explain whether you would evoke preparatory or mobilizing change talk with your service user, and why. 

HART CITY CSE SCENARIO

  

Alma

Alma is a 40-year-old woman who has just been admitted to the Hart City Substance Abuse Clinic via a court order. She had three driving under the influence (DUI) offenses in the past year. Recently, while driving under the influence, she jumped a curve and hit a pedestrian. He survived; however, he needs extensive rehabilitation. The police convicted Alma of reckless endangerment as well as drunk driving and ordered her to an inpatient facility. Alma is married with four children all under the age of 16. She is the chief executive officer (CEO) of a multinational organization. Her job requires her to travel two weeks each month. Early on, Alma and her husband decided that he would stay home and raise the children. He is also a writer, but he has yet to publish anything significant. Alma has been the sole financial provider for her family for 16 years. Alma adamantly denies that she has a substance abuse problem and does not want to stay in treatment for the required 30 days. She is hostile towards the staff and in need of an intake assessment and referral for treatment. Her family is also in need of referrals for emotional support.
