What is meant by the conception of Plum in the Golden Vase as an encyclopedic narrative? How is our assumption that a text has a single author who penned it from start to finish modified by the textual history of some of the other texts we have studied, for example, Guan Hanqing’s play “The Injustice to Dou E”?

During the meeting, review the Microbiological Diseases: Nonrespiratory Infectious Diseases Case Study below:Mr. Jones is a 69-year-old man who was admitted to the hospital 10 days earlier with a diagnosis of acute diverticulitis. He was given intravenous fluids and empiric antibiotic coverage with ceftriaxone and metronidazole. His antibiotics were stopped after 7 days, and he continued to do well until today, when he developed abdominal pain, fever, and diarrhea. A diagnosis of Clostridium difficile colitis was made, and antibiotic treatment was initiated.Discuss the following questions:What diagnostic test would confirm the diagnosis?What risk factors did Mr. Jones have to acquire a Clostridium difficile infection?Why is oral but not intravenous vancomycin a potential treatment option for this infection?One person from each group should respond to this discussion with a link to their group’s recording and a summary of the discussion that took place.

Have you ever wondered what infections look like from the pathogen’s perspective? If our immune systems are so amazing, why do we get sick at all? During this simulation, you’ll undertake a series of challenges in preparation for an important global health investigation. Can you complete each task and add to the planet’s immunological understanding?ActivityResearch and answer the following questions:How does the immune system protect against pathogens?What are the similarities and differences between the innate and adaptive immune systems?What is immunological memory and why is it important?This assignment should be 2–3 double-spaced pages in APA (7th ed.) format and have at least one outside resource. Be sure to cite your resources.

The Role of Diversity in Public Health WorkFor this discussion, analyze how your proposed project acknowledges the value of diversity in your attempt to address or solve a public health problem. Consider the information shared from the What Is Diversity? multimedia piece from this unit’s study and discuss the possible cultural difficulties in this project. How do you anticipate overcoming those difficulties?

InstructionsReading scientific literature is important in professional development for anyone in the medical field. However, reading research articles and scientific articles can be challenging. This activity will reinforce your understanding of microbiology, as well as teach you how to read, comprehend, and apply concepts useful for microbiology.ActivityRead the following articles:”How to Prevent the Spread of Respiratory Illnesses in Disaster Evacuation Centers” (Links to an external site.)Citation: CDC: Center for Disease Control and Prevention. (n.d.) How to prevent the spread of respiratory illnesses in disaster evacuation centers. https://www.cdc.gov/disasters/disease/respiratoryic.html”Respiratory Diseases” (Links to an external site.)Citation: Matteelli, A., & Saleri, N.

Travel Medicine, 561–572. https://doi.org/10.1016/b978-0-323-03453-1.10057-4Answerthe following questions in 1–2 double-spaced pages following APA (7th ed.) format.How are the majority of respiratory diseases spread?Identify three important control measures to help decrease the spread of respiratory disease? Which of these measures is most effective in your locale?Identify two diseases from the articles that you found most interesting. Explain.

Reflection Paper 2 (2/15)Choose this prompt for Reflection Paper 2 OR the prompt for 3/8. Do not submit both.General instructions are found in your syllabus (pgs. 5-6). Please review these first, since some of you missed the idea of the reflection paper because you only followed the specific prompt, not the general instructions!Reflection Paper 2: InfancyReflect on the birth of a child you know in their family context. Look at how this birth impacted family members, changed the course of development for adults (e.g., caring for an infant with Down syndrome or physical disability), and/or was impacted by or impacted larger contexts as well (for instance, someone lost a job, birth required parents to get to know deaf culture, an adoption). OR a lternatively, you may observe or interact with an infant and reflect on what you noticed about infant development and parent or caregiver-infant interaction.AssignmentReflection Paper 2 (3/8)General instructions are found in your syllabus (pgs. 5-6). Please review these first, since some of you have missed the idea of the reflection paper because you only followed the specific prompt, not the general instructions!Reflection Paper 2: Early ChildhoodFor this paper, you should take some time to observe a small child or children (18 months to 5 years), or to interact with one you know. Write a reflection paper on what aspects of development you noticed, including communication, frustration tolerance, emotion expressed, word usage, cognitive development, body coordination, and so on. Possible places to observe, in addition to homes: with family or friends, at grocery store, Saturday Farmer’s Market, library, neighborhood, religious service, outdoor space). ORIn family life, a young child is both impacting and being impacted by the family into which they are born. How we were experienced by our parents and family members as babies and small children may become part of the family narrative, with implications for attachment, temperament and goodness of fit, family dynamics, and larger family and cultural ideas and myths. You may write about how you were experienced as a young child. Or you may write more generally about family dynamics in your early years
