In your own words, what would you say to the patient? Please be sure you cover everything that was seen in his lungs, heart and adrenal glands. DO NOT use medical terminology. You need to discuss calcifications, adrenal adenomas, the coronary artery, cardiomegaly, lymph nodes, and all of the nodules that were listed (mediastinal, pretracheal, precarinal, subcarinal) and the fact that intravenous contrast is now being recommended.

CT OF THE CHEST WITHOUT CONTRAST HISTORY: Shortness of breath. FINDINGS: CT examination of the chest was performed without intravenous contrast enhancement. Median sternotomy has been performed with dense calcifications of the coronary arteries and calcific plaque formation in the aortic arch. There is mild cardiomegaly. The upper pole of the right thyroid lobe demonstrates a 0.8 x 0.6 cm nodule. No enlarged axillary or supraclavicular lymph nodes are evident. There are numerous enlarged mediastinal lymph nodes, including a 1.4 x 1.1 cm pretracheal node on image #17, a 1.9 x 1.7 cm precarinal node on image #24 with marginal calcification, and a 2.1 x 1.6 cm AP window node on image #23. There is a nodal conglomerate in the subcarinal region, which measures 4 x 2 cm. Bilateral hilar adenopathy is present but this is difficult to accurately measure without intravenous contrast to delineate between hilar vasculature and nodal structures. There are a few small ill-defined nodules within the left upper lobe which measure 2-3 mm in diameter. The posterior superior portion of the left lower lobe contains a 1.2 x 0.4 cm pleural plaque (image #38). In both the posterior right base and superior segment of the right lower lobe, there is atelectasis. The aortic descent and visualized portions of the abdominal aorta show moderate calcified plaque formation. No pleural effusion is evident. Within the visualized abdomen, the adrenal glands are both enlarged, measuring 2.1 x 2.5 cm on the left and 1.9 x 3 cm on the right. The adrenals show homogenous low attenuation compatible with bilateral adrenal adenomas. There are numerous bilateral nonobstructive renal calculi. No abdominal nodal enlargement is evident in the visualized portions of the abdomen. IMPRESSION: 1. There is widespread bilateral hilar and mediastinal nodal enlargement. At least some of these nodes show both internal and marginal calcifications, which may suggest a granulomatous process. Further evaluation, which could include both followup and additional evaluation for other enlarged lymph nodes within the body, is suggested. 2. Bilateral low attenuation enlargement of the adrenal glands. This may represent bilateral adrenal adenomas. 3. Evidence of prior surgery of the chest with extensive bilateral coronary artery calcifications. 4. Mild to moderate calcified plaque formation of the descending aorta.

Discussion:

The Strategy of Cultivating Interdependence

All of life is an opportunity to think, relate, and work strategically. However, most people do not really think well, and they certainly do not think strategically by nature.  This IS something that can be learned!

In Covey's chapter on "Paradigms of Interdependence," he talks about the "Emotional Bank Account" that we have in our relationship with others, and he identifies "Six Major Deposits" that we can make into this emotional bank account by our actions, behaviors, and habits toward others. (Of course, we can also make "withdrawals" too.)

As you read about these deposits or withdrawals from our emotional bank accounts with others, it seems like "common sense," though this work is based upon solid research too. However, these behaviors are not as "common" as one would wish, which accounts for the interpersonal difficulties that plague our individual lives and the organizations in which we work.

Questions:

1) Do you really believe a person can retrain their thinking so that they learn to think more strategically and effectively as a habit of thought and life?

2) How would one go about learning how to think more strategically and training themselves actually to do so?

3) Do you really believe a person can learn new skills and behaviors in their interpersonal relationships so that over time they can dramatically improve their relationship with everyone important in their life?

4) How could one go about learning how to make Covey's six major deposits into others' emotional bank accounts? What could one do to make these deposits on a regular, reflexive, habitual basis?

Sal Amato operates a residential landscaping business in an affluent suburb of St. Louis. In an effort to provide quality service, he has concentrated solely on the design and installation of upscale landscaping plans (e.g., trees, shrubs, fountains, and lighting). With his clients continually requesting additional services, Sal recently expanded into lawn maintenance, including fertilization.

The following data relate to his first year’s experience with 56 fertilization clients:

Each client required six applications throughout the year and was billed $41.00 per application.

Two applications involved Type I fertilizer, which contains a special ingredient for weed control. The remaining four applications involved Type II fertilizer.

Sal purchased 5,700 pounds of Type I fertilizer at $0.60 per pound and 10,700 pounds of Type II fertilizer at $0.47 per pound. Actual usage amounted to 4,000 pounds of Type I and 8,150 pounds of Type II.

A new, part-time employee was hired to spread the fertilizer. Sal had to pay premium wages of $12.20 per hour because of a very tight labor market; the employee logged a total of 179 hours at client residences.

Based on previous knowledge of the operation, articles in trade journals, and conversations with other landscapers, Sal established the following standards:

Fertilizer purchase price per pound: Type I, $0.57; Type II, $0.49

Fertilizer usage: 47 pounds per application

Typical hourly wage rate of landscape personnel: $9.70

Labor time per application: 40 minutes

The operation did not go as smoothly as planned, with customer complaints actually much higher than expected.

Required:

1. Compute Sal’s direct-material variances for each type of fertilizer.(Indicate the effect of each variance by selecting "Favorable" or "Unfavorable". Select "None" and enter "0" for no effect (i.e., zero variance). Round your intermediate calculations and final answers to 2 decimal places.)

	Direct-Material Type I Type II Price variance Quantity variance Purchase price variance

2. Compute the direct-labor variances.(Indicate the effect of each variance by selecting "Favorable" or "Unfavorable". Select "None" and enter "0" for no effect (i.e., zero variance). Do not round intermediate calculations and round your final answer to 2 decimal places.)

	Direct-Labor Rate variance Efficiency variance

3-a. Compute the actual cost of the client applications. (Note: Exclude any fertilizer in inventory, as remaining fertilizer can be used next year.)(Do not round intermediate calculations. Round your answer to 2 decimal places.)

3-b. Calculate the profit or loss of Sal’s new lawn fertilization service.(Do not round intermediate calculations. Round your answer to 2 decimal places.)

4. On the basis of the variances that you computed in parts (1) and (2) was the new service a success from an overall cost-control perspective?

(Indicate the effect of each variance by selecting "Favorable" or "Unfavorable". Select "None" and enter "0" for no effect (i.e., zero variance). Do not round intermediate calculations. Round your answer to 2 decimal places.

5. Should the fertilizer service be continued next year?(yes or no)

3. Are Angry People More Likely to have Heart Disease’? People who get angry easily tend to be more likely to have heart disease. That is the conclusion of a study that followed a random sample of 12,986 people from three locations over about four years. All subjects were free of heart disease at the beginning of the study. The subjects took the Spielberger Trait Anger Scale, which measures how prone a person is to sudden anger. The 8474 people in the sample who had normal blood pressure were classified according to whether they had “coronary heart disease” (CHD) or not and whether they had low anger, moderate anger, or high anger according to the Anger Scale.  The classification summary is given.

	Low Anger	Moderate Anger	High Anger
	53	110	27
No CHD	3057	4621	606

                Use R to conduct a test to see whether we can conclude at α=0.05, that angry

                people are more likely to have heart disease.
