Introduction 1 Oluebube Ogoazi Chamberlain University Critical Reasoning Dr. Stephens March 10, 2024 2 What benefits would defunding the police actually bring? I have chosen this topic specifically because police brutality has become a more pressing issue since social media became wide spread. Personal history also connects me to this issue due to incidents that have happened with my brother. My brother has faced police brutality from Nigeria even moving to the United states. The reason this topic was chosen is because there are a number of reasons why the police should be defunded, including the reduced biases, less violent crime by police and relocating funds to working and succeful organizations. One of the main reasons why police should be defunded is reduced biases. Policing has been effective I going after certain groups of people including, foreigners, marginalized people and people of certain races. Racial profiling indulges and perpetuates the description that already marginalized people face. Police should not be given the opportunity to “guess” who has committed a crime. Believing someone is crime perpetrator without evidence or facts but solely on how they look like leads to violence and trauma. Another human or group of people should not wield that authority. Defuding the police also reduces violence and death caused by biases, discrimination and racial profiling. Police having the authority to choose who they believe is guilty is detrimental to the people. Detrimental because it leads to violence, severe injury and sometimes death of people in the community. These incidences have happened more often than none, and with the prevalence of social media it is becoming a more informed about topic (PBS news). For example, the incident with George Floyd in 2020, which became popular because of the media. These multiple experiences are part of the reason that people and citizens do not have trust for the police. The original purpose of the police was “slave patrol” 3 according to the NAACP and that has become increasingly known to the public. People that are meant to protect and serve as well as gain and retain people’s trust are evidently not doing their jobs. Still, they consume tax payer dollars when these funds can be allocated into an organization that actually works. 4 References The Origins of Modern Day Policing. (n.d.).

Diagram Answer Based on the scenario provided, here’s a step-by-step guide on how to create a data flow diagram (DFD) for the Medical Center of DeVry: Step 1: Identify External Entities External entities are the sources and destinations of information entering and leaving the system. In this case, the external entities could be the Patient, Physician, Scheduling Clerk, Registration Clerk, Radiology Technician, and Radiologist. Step 2: Identify Processes Processes are the activities or functions that transform the data from one form to another. In this scenario, the processes could be “Schedule Examination”, “Check-in Patient”, “Perform Examination”, and “Evaluate Examination”. Step 3: Identify Data Stores Data stores are repositories of data in the system. In this scenario, the data stores could be “Patient File”, “Radiology Schedule File”, and “Encounter Database”. Step 4: Identify Data Flows Data flows are the routes that data takes between external entities, processes, and data stores. In this scenario, the data flows could be “Demographic and Insurance Information”, “Test and Diagnosis Information”, “Appointment Date and Time”, “Check-in Confirmation”, “Examination Data”, and “Examination Report and Diagnosis”. Step 5: Draw the DFD Using a software like Microsoft Visio, start by placing the external entities around the edges of the diagram. Then, place the processes in the middle of the diagram. Connect the entities and processes with arrows representing the data flows. Finally, represent the data stores as two parallel lines and connect them to the relevant processes with arrows. Remember, arrows should be labeled with the name of the data that is flowing, and each process should have at least one data flow in and one data flow out. The direction of the arrow indicates the direction of the data flow. Step 6: Review and Refine the DFD Review the DFD to ensure that it accurately represents the scenario. Make any necessary adjustments to improve clarity or accuracy. Step 7: Submit Your Lab Once you’re satisfied with your DFD, submit it according to your instructor’s guidelines. Please note that this is a general guide and the specifics may vary depending on the exact requirements of your assignment and the features of the software you’re using.

follow all directions When involving stakeholders in the data collection and analysis process, it is essential for them to understand the difference between validated data versus basic data points. It is important to assure the stakeholders that the quantitative data are quality information that has been looked at multiple ways, such as tracking the data by hand, using grid organizers to examine the data, reconciliation reports, and/or verifying data relevant to the benchmarks set. These efforts are driven by a desire to validate the numbers being put into recording spaces (e.g., computers, Excel spreadsheets) and to make sure the numbers look correct, as much as possible. Likewise, when examining qualitative data, you want to validate the information/data that subjects are giving you. For example, you may have the subjects look at and verify the accuracy of transcripts and/or you may read back to them what they said and ask them to confirm, deny, and/or clarify that the information gathered is accurately represented. Another method of validation is triangulation of data in research studies whereby multiple sources of data or multiple approaches to analyzing the data are employed as well as multiple people looking at outcomes to make sure the data look correct. Validated data are generated using data collection and analysis processes that can be replicated and yield similar results in other contexts. A primary intent of involving stakeholders in the use of validated data is to generate trust in the process. Therefore, involving stakeholders in data collection and analysis requires educating them about the related process(es) as simply and precisely as possible, whether they are part of the data being collected or consumers of the reported data. For this Discussion, you will assume the role of a consultant and provide an evidence-based approach for an organization regarding getting stakeholders involved to help with data collection and analysis. RESOURCES Be sure to review the Learning Resources before completing this activity. Click the weekly resources link to access the resources. WEEKLY RESOURCES TO PREPARE · Consider the following scenario: You are a consultant coming into an organization to help with data collection and analysis. How will you get the stakeholders involved in the process so that they understand the importance of validated data use, versus nonvalidated data, for the organization? · Select two scholarly articles that validate your approach with the stakeholders in the scenario. · Review your Levels of Evidence table, consider where and why the articles fit in the table. ( Note: You will include the Levels of Evidence table in your post.) BY DAY 3 Post your response to the consultant scenario. · Part 1: How will you get the stakeholders involved in the process so that they understand the importance of validated data use, versus nonvalidated data, for the organization?

HEALTH AND NUTRITION Week Two – Preventing Infection in Early Childhood Centers Part A Time to Apply Critical Thinking Preventing Infection in Early Childhood Centers As parents drop off their child at a childcare center- they are probably thinking: Will they eat enough? Will they take a nap? Will she miss me? How will he get along with the other children? These are all important questions, because they want to be assured that their child is safe and healthy. We know children share a lot of germs. Respiratory and gastrointestinal infections spread quickly in early childhood facilities. According to the Centers for Disease Control and Prevention, an average of 20,000 children younger than 5 years of age are hospitalized each year because of flu-related complications. After reading Chapter 8 and 9 in your text about preventing infections, reflect on how centers might prevent the spread of infections and then review this summary of an articleLinks to an external site.

Resources Part B Strategies to Maximize Mental and Physical Health After the Pandemic We can probably all agree that going through the COVID-19 pandemic has caused multiple challenges for many people and their families. Many families found themselves sheltering in place, some found themselves unemployed, some had to work additional hours as essential workers, some found themselves or their loved ones became infected or died. Stress and anxieties were common as a result of the pandemic. One of our tasks as early childhood professionals is to prevent illnesses to help keep children and staff healthy and safe. Yet, there is still work to do after a crisis has happened. You will read two articles and then reflect upon designing strategies to maximize the mental and physical health of children and adults in early care and education programs in accordance with culturally, linguistically, and developmentally sound practices. Instructions 1. Read Lesson 6 (pp. 8-9) of the article Learning renewal – Ten lessons from the pandemic Download Learning renewal – Ten lessons from the pandemic Links to an external site.

The question asks if age has an impact on the survival chances of MI patients. MI stands for Myocardial Infarction which is commonly referred to as heart attack (Institute of Medicine, 2010). When people grow older, their body organs become weaker, and their functionality drops. This implies that an older patient’s heart is not as strong as a young person’s and in case of a heart attack, the mortality rate for older people is higher. The long-term survival of patients aged 65 and above with acute myocardial infarction is 65% (Kappagoda & Greenwood, 2012). Age affects the survival of MI patients. Younger patients have greater survival rates than older ones. The younger population is generally healthier and stronger; therefore, they have better chances. Their immunity is also higher and this generally boosts their health (Morrow, 2016). On the contrary, the older population is weaker and has minimal chances of surviving a heart attack.

follow all directions IHP 525 Module Five Problem Set Newborn weight. A study takes a SRS from a population of full-term infants. The standard deviation of birth weights in this population is 2 pounds. Calculate 95% confidence intervals for μ for samples in which: n = 81 and mean = 7.0 pounds n = 9 and mean = 7.0 pounds Which sample provides the most precise estimate of the mean birth weight? Interpret the CI you computed in part a). P-value and confidence interval. A two-sided test of H0: μ = 0 yields a P-value of 0.03. Will the corresponding 95% confidence interval for μ include 0 in its midst? Will the 99% confidence interval for μ include 0? Explain your reasoning in each instance. Menstrual cycle length. Menstrual cycle lengths (days) in an SRS of nine women are as follows: {31, 28, 26, 24, 29, 33, 25, 26, 28}. Use this data to test whether mean menstrual cycle length differs significantly from a lunar month using a one sample t-test. (A lunar month is 29.5 days.) Assume that population values vary according to a Normal distribution. Use a two-sided alternative. Show all hypothesis-testing steps. Menstrual cycle length. Problem 3 calculated the mean length of menstrual cycles in an SRS of 9 women. The data revealed days with standard deviation s = 2.906 days. 1. Calculate a 95% confidence interval for the mean menstrual cycle length. 1. Based on the confidence interval you just calculated, is the mean menstrual cycle length significantly different from 28.5 days at α = 0.05 (two sided)? Is it significantly different from μ = 30 days at the same α-level? Explain your reasoning. (Section 10.4 in your text considered the relationship between confidence intervals and significance tests. The same rules apply here.) Water fluoridation. A study looked at the number of cavity-free children per 100 in 16 North American cities BEFORE and AFTER public water fluoridation projects. The table below lists the data. You will need to manually type the data into StatCrunch to use that tool to calculate the requested information. 1. Calculate delta values (After – Before) for each city. Then construct a stemplot or boxplot of these differences. Interpret your plot. 1. What percentage of cities showed an improvement in their cavity-free rate? 1. Estimate the mean change with 95% confidence (i.e. compute a 95% CI for the mean difference).
