Measuring Morbidity: Prevalence and Incidence Examining data for prevalence and incidence of a disease or pathology helps public health officials to understand how the disease or pathology is affecting a specific population over a period of time. By understanding this, strategies can be introduced to intervene or address the issues.For this assignment, examine prevalence and incidence to measure morbidly for a disease. Read the scenario below and complete the assignment as instructed.ScenarioIn Community X (population 20,000), an epidemiologist conducted a prevalence survey in January of 2012 and reported an HIV prevalence of 2.2%. Over the next 12 months, the department of health reported an additional 50 new HIV cases between February 2012 and January 2013. The total population stayed constant at 20,000.Part 1How many people had HIV in January 2012? Present or describe the formula you used to arrive at your answer.Calculate the incidence rate assuming no HIV-related deaths over the 12-month period. Present or describe the formula you used to arrive at your answer. Be sure to clearly indicate the numerator and denominator used in your calculation and include an appropriate label for the rate.In a summary of 200-250 words, interpret the results and discuss the relationship between incidence and prevalence. Discuss whether or not the epidemiologist should be concerned about these new HIV infections, assuming a previous incidence rate of 0.5 per 1,000 person-years prior to this updated risk assessment.You are required to cite to a minimum of three sources to complete this assignment. Sources must be published within the last 5 years and appropriate for the assignment criteria and public health content.While APA style is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA formatting guidelines, which can be found in the APA Style Guide, located in the Student Success Center. This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.

Conjectures and Refutations is one of Karl Popper's most wide-ranging and popular works, notable not only for its acute insight into the way scientific knowledge grows, but also for applying those insights to politics and to history. It provides one of the clearest and most accessible statements of the fundamental idea that guided his work.Read the first part of Popper's paper (pages 1-10) or watch the video (which reads the first ten pages) and post your personal opinion about the concept of falsification. You can use the following questions to guide your answer: Do you think it is a valid way to define scientific practice? do you think it can be applied to all branches of science? Did you change your mind about inductive reasoning? Do you think psychoanalysis is scientific? Do you think Popper's falsification theory limits what we can consider science? Please be sure you use other sources if necessary to learn more about the subject if you need to. Name your references if you use them in your post. You DON'T have to write a comment to your classmates. This video reads pages 1 to 10 of the attached pdf that contains the full essay first published as part of the book Conjectures and Refutations.
