Psychological Foundations of Leadership Essay
QUESTION 1
Emotional intelligence encompasses the ability to recognize and understand emotions, which is vital in personal decision making and in guiding others. To achieve this, one must effectively understand the components of emotional intelligence. The first component is self-awareness, which refers to the ability of a person to understand their areas of strength and weakness (Kasapi & Mihiotis, 2014). It also demonstrates the ability of an individual to understand the impact of their actions on others. Self-awareness enhances the ability to learn from past mistakes and to embrace constructive criticism.
The second component is self-regulation. This is concerned with the aptitude to control one’s emotions and moods, such that one can listen without judging or think before an action among other things (Narayan and Narashiman, 2012). It also encompasses openness to change and self-integrity. The third component is internal motivation, which refers to factors that influence an individual’s inner passion (Kasapi & Mihiotis, 2014). This goes beyond external rewards such as money and is more about deriving joy and gratification from things that are of interest to an individual.
The fourth component is empathy, which is the ability to treat others based on their emotive reactions. It is about placing oneself in another’s position and thus seeking to understand them based on this. The last component is social skills, which are of great significance in network building, communication and teamwork (Narayan and Narashiman, 2012. Individuals with emotional intelligence are more likely to be team leaders and are experts in persuasiveness and leading change.
The importance of emotional intelligence cannot be underestimated, given the role played by EQ in promoting organizational success. Emotional intelligence is important because it promotes teamwork and ability to effectively communicate with others (Kasapi & Mihiotis, 2014). Understanding others’ emotions ensures that individuals can control their emotions, such that their contributions and decisions are made in a more objective and communication is clearer.
Having greater self-awareness is critical role in enhancing action accountability and this leads to better performance. Emotional intelligence is also important because it promotes authenticity. When one is emotionally intelligent, they tend to be consistent in applying their own values and judgments and this creates predictability and authenticity (Dayo, et al., 2012). Emotional intelligence is also important in promoting connection with others, which leads to the development of better relationships.
When a leader has high EQ, they can connect with their followers better because they not only understand them but they can also express their emotions and passion with ease. Furthermore, emotional intelligence is useful in promoting respect. When an individual understands themselves and others, they are more likely to have self-respect and respect for others as well, and treat people equally. Internal motivation is important in driving optimism and desire to achieve even in the midst of obstacles.

Okun’s Law of Data Analysis
Data Exercise 1 Okun’s Law
This exercise is designed to assess your ability to manipulate and analyze data in accordance with Course Competency: Locate, analyze, and interpret macroeconomic data.
Instructions:
Put all of your work in one file;
Write your name in the header;
We need to see your work in Excel (i.e., formulas). Do not copy and paste numbers from your original worksheet to a new worksheet. When submitting, make sure that the cells in your worksheet show formulas.
After you finish the assignment, name your file LastnameDE1.xls (or .xlsx, depending on the version of Excel). Note that you do not have to write the .xls suffix by yourself – Excel will do it automatically, and
Upload it to the Data Exercise Section of the Blackboard.
Background:
One of the most regular relationships in macroeconomic data is the relationship between the unemployment rate and the growth rate of real GDP. Specifically, the relationship is between the percentage-point change in the unemployment rate from one year to the next and the growth rate of real GDP:
“Percentage Change in Real GDP = α – ß(“Percentage – point Change in Unemployment Rate”)
Okun’s Law
Assignment:
You are hired as a business consultant to a Senator. She heard the association between the unemployment rate and economic growth, and asks you to estimate the relationship so that she could propose a policy to lower the unemployment rate.
) and graph the relationship of the two variables.
To obtain data for this exercise, click “List of Statistical Tables” under the most recent Report, and download relevant tables.
You need two tables (real gross domestic product and civilian unemployment rate) for this exercise. After downloading the two Excel files, combine them into one file. To combine two files into one, use “Home-Format (Cells)-Move or Copy Sheet” and move one sheet to the other “book.”
You would need only two series (Gross Domestic Product and Unemployment Rate of All Civilian Workers). You may want to delete all unnecessary columns and sheets to simplify your worksheet.
You only need annual data. At the bottom of each table, most recent data are given quarterly (GDP) and monthly (unemployment rate). You may want to delete unnecessary rows to simplify your worksheet.
In your graph, put the percentage-point change in unemployment rate on the horizontal axis and the GDP growth rate on the vertical axis.
Use “Scatter Plot” to plot the two series on a graph, taking the change in the unemployment rate on the horizontal (X) axis and the growth rate in real GDP on the vertical (Y) axis.
Insert the linear trend line. To insert the trend line, put your cursor on one marker on your scatter plot, right-click the mouse, and choose “Add Trend Line” from the menu. When “Trend Line Option” menu appears, choose “Display Equation on Chart.”
Note that Excel gives you the relationship in the format. (insert your equation)
Given the relationship you estimated, how much should real GDP grow to reduce the unemployment rate by 2 percentage points?
For your reference, an example of the graph is provided below (parameter values in the equation are hidden). If done correctly, your graph should look like the one below.
If it doesn’t, then re-do it. Be careful your data represents exactly what change is asked for!!

Interactions and definitions of isolation and loneliness
Write an essay that compares and contrasts isolation and loneliness, defining both using multiple theories/theorists. It needs to relate how both affect people (especially in the workplace)
Some people use the words “isolation” and “loneliness” interchangeably, but this does not reflect the true meaning of each term. Isolation may lead to loneliness, and in some cases, loneliness may exacerbate isolation. Both have been found to occur with other mental health issues such as anxiety or depression.
Knowing how loneliness and isolation are distinct and related can help people who struggle with them best address and work through these issues. Here are a few things to know about handling loneliness and social isolation in your life.

Catheter Associated Urinary Tract Infections
Catheter Associated Urinary Tract Infections
Use evidence-based nursing interventions to research whether early removal of indwelling urinary catheters and shunning non-evidence based interventions does contribute to a significant decline in the risk of catheter-associated urinary tract infections among inpatients with indwelling urinary catheters.
Below is a partial answer to the above homework questions by one of our writers. If you are interested in a custom non plagiarized top quality answer, click order now to place your order.
Catheter Associated Urinary Tract Infections
Statistics indicate that nearly 13,000 deaths occur annually due to urinary tract infections (UTIs). Approximately 75% of UTIs are linked to urinary catheters. Statistics further show that approximately 15-25% of inpatients use catheters. Still, UTIs constitute the fourth most prevalent healthcare related infection in the U.S, with over 93,000 reported inpatient incidences in 2011.
Besides, UTI’s constitute 12% of the total infections reported in acute care, while 12-16% of hospitalized adult patients have higher chances of using indwelling urinary catheters. The study of catheter-associated urinary tract infections (CAUTI) is essential as it highlights evidence-based nursing interventions needed for early removal of indwelling urinary catheters aimed at containing possible risks of CAUTIs among inpatients with indwelling urinary catheters.
Catheter Associated Urinary Tract Infections
Abstract
The research has established that the use of evidence-based nursing interventions for early removal of indwelling urinary catheters and shunning non-evidence based interventions does contribute to a significant decline in the risk of catheter-associated urinary tract infections among inpatients with indwelling urinary catheters.
Catheter Associated Urinary Tract Infections
According to Huang (2016), a urinary tract infection is a type of infection that affects the urinary tract and other parts of the urinary system including the bladder, urethra, kidney, and ureters and is the most prevalent healthcare related infection.
Center for Disease Control (CDC) statistics indicate that 13,000 deaths occur annually due to urinary tract infections (UTIs).Nearly 75% of the UTIs are linked to urinary catheters, while approximately 15-25% of inpatients use catheters (Hartley, 2015). Piechota (2016) defines indwelling urinary catheter as the urinary discharge tube that is inserted into the patient’s urinary bladder via the urethra and left in situ while continuously connected to a closed urinary drainage system. Urinary Tract Infections (UTIs) constitute the fourth most prevalent healthcare related infection with over 93,000 reported incidences in hospitalized patients in 2011 (Hartley, 2015).
Thus UTI’s constitute 12% of the total infections reported in acute care. Statistics further suggests that nearly all-healthcare related urinary tract infections occur as a result of the improper instrumentation of the urinary tract. CDC Statistics also shows that 12-16% of hospitalized adult patients have higher chances of using indwelling urinary catheters.

Common Legal Liabilities to Nurse Managers Essay
Introduction
Legal liabilities for medical professionals refer to potential obligations faced in the course of their work, for which they may be answerable to by the law (Flight and Pardew, 2017). These may include any damages, injuries, negligence or malpractices when dealing with patients (Flight and Pardew, 2017). In the case of nurse managers, the major point of contention is how the manager can he held responsible for damages caused by nurses working under them.
Wilkinson (2016) notes that the nursing manager has a duty to ensure that nursing staff provide the highest level of care and that failure to do so can result in legal liabilities in the event of patient injury. While legal liabilities may be unavoidable in certain circumstances, it is imperative that nurse managers take necessary precautions to avoid legal liabilities to the greatest extent possible. The purpose of this paper is to examine potential legal obligations that nurse managers face and how these can be minimized.
Common Legal Liabilities to Nurse Managers Essay
While nurse managers are faced with a considerable number of legal liabilities, these liabilities can be minimized by taking precautions aimed at promoting patient safety. This discussion recognizes the opposing viewpoint, that some accidents that occur in the course of a nurse’s work are unavoidable and that nothing much can be done to prevent them (Yoder-Wise, 2013). This makes it difficult for nurse managers to minimize such legal obligations. However, this paper argues that it is possible for nurse managers to minimize legal liabilities through effective management of their subordinates.
Common Legal Liabilities to Nurse Managers Essay
Discussion
Nurse managers face various potential legal liabilities including negligence in the supervision of nurses, negligence in hiring, negligence in quality control, failure to maintain standards of care, failure to report inferior medical care, and negligent retention of ineffectual employees (Yoder-Wise, 2013; CPH, 2018; Wilkinson, 2016; Kelly, 2011). Negligence in supervision refers to a legal liability where the nursing manager can be held responsible for the actions of nurses working under them, based on their lack of effective supervision of how the nurses are performing their job (Wilkinson, 2016)……

Which of the following sources of market inefficiency would be most easily exploited?
Dollar-cost averaging means that you buy equal dollar amounts of a stock every period, for example, $500 per month. The strategy is based on the idea that when the stock price is low, your fixed monthly purchase will buy more shares, and when the price is high, fewer shares. Averaging over time, you will end up buying more shares when the stock is cheaper and fewer when it is relatively expensive. Therefore, by design, you will exhibit good marketing timing. Evaluate this strategy.
