    We have all had moments where communication meant the difference between resolving an issue and creating one. Describe an event or incident where being an active listener allowed you to calm a situation. Here are some questions to consider:

    · What ways did dialogue contribute to diffusing the situation?

    · Did you or the other people involved demonstrate body language cues that signaled the situation was escalating or diminishing?

    · How did the situation resolve?

    · If you could revisit that situation now, what would you change?

    Effective Communication in Art

     

    Click on the picture icon to the right and insert images of art (any visual representation) that communicates new understanding of diversity issues. This can be anything from a multi-racial family to the physically active elderly sky diving or water skiing (defying the stereotypes on aging). Click on the word “Text” and describe the message being communicated and explain why some people might miss or ignore this message. If necessary, reference the image on the References page.

     

     

     

     

     

     

     

     

     

    Listening to the Voiceless

    Go to this YouTube channel and view three or more interviews with the homeless that are not from your race/ethnicity/gender group. Select one that you feel created the most effective message to help yourself and others understand the unique issues facing the homeless population. Once you select your video, share the URL in the textbox below. Be sure to reference the video on the References page.

    Address the following questions:

     

    1. What feelings or emotions did the video draw out in you? What made you connect to the person being interviewed?

    2. What stereotypes did you find yourself falling into initially?

    3. How might this video or others like it bring an end to othering of the homeless?

    Literature and Identity Power

     

     

    Literature has been used over the centuries in assimilating cultures and establishing cultures, but in more modern times it has become an effective tool to bring ‘voice’ to the marginalized and underrepresented. One example is Amy Tan, an Asian American writer of the novel, The Joy Luck Club, and many others. Her essays often focus on Identity Power in ways that are inclusive to all groups which is one reason her work has been so effective. Click on this link and read her essay “Mother Tongue.” In the textbox below address the following questions:

     

    1. How does the essay bring a new perspective to the idea of language?

    2. In what ways could you directly relate to her explanation of ‘many Englishes?’

    3. How does Amy Tan expose the need for effective listening?

    Reflections

     

    Now that you have had the opportunity to learn more about the importance of listening as a first step in effective communication among all groups, please address the following to complete your Unit 3 template.

    1. The headlines are filled with injustices each and every day, and it seems nothing is being done to combat the negative communication in modern society. Think of an issue that directly impacts your immediate community and create a short dialogue to put communication within that community on a positive track.

    2. Take a few moments to imagine you were one of the ‘Invisible People’ being interviewed. What would your message be to the audience? How might you say to help bring about an effective dialogue that begins the process of restoring the dignity of those who are financially disabled?

The Discovery Of The Gene Encoding Leptin

/in /by

Our current textbooks teach us that the hypothalamus is an important integration site for adiposity and satiety signals, along with nutrients and information related to the rewarding properties of food (pleasant taste, good memories, good company). This of course was not always textbook information. Some of the earlier clues for this came from experiments by G.R. Hervey in the late 1950s. He was the first to use parabiosis to predict that a circulating factor existed that relays information on our body’s fat mass to the hypothalamus.

Parabiosis is an experimental paradigm where two animals are surgically joined in a way that they will develop a shared circulation. Factors circulating in either of the ‘parabionts’ could thus cross over into the circulatory system of the other.

The discovery of the gene encoding leptin

Our current textbooks teach us that the hypothalamus is an important integration site for adiposity and satiety signals, along with nutrients and information related to the rewarding properties of food (pleasant taste, good memories, good company). This of course was not always textbook information. Some of the earlier clues for this came from experiments by G.R. Hervey in the late 1950s. He was the first to use parabiosis to predict that a circulating factor existed that relays information on our body’s fat mass to the hypothalamus.

Parabiosis is an experimental paradigm where two animals are surgically joined in a way that they will develop a shared circulation. Factors circulating in either of the ‘parabionts’ could thus cross over into the circulatory system of the other.

Side note, such experiments, like any animal studies, are subject to tight ethical oversight where the scientific value is balanced against the degree of pain or discomfort animals experience. Obtaining approval for such parabiosis experiments today would require strong justification and could well be denied.

Hervey’s experiment started with a rat where he damaged (lesioned) the VentroMedial Hypothalamus (VMH). He then waited for some time before parabiosing this animal to a normal lean rat.

Hervey hypothesized that there existed a circulating factor (i.e. a hormone) that acted as a ‘lipostat’ by conveying information about fat mass to the VMH and that damaging the VMH would make the animal unable to respond to this factor. The VMH-lesioned animal would start to eat excessively (hyperphagia) and become morbidly obese as a consequence (think back of the girl with the craniopharyngoma). The lean parabiont however, would stop eating and die of starvation.Question: Why this is the case. Please make sure you understand this before moving on.

Experiments that suggested that the lipostat predicted from Hervey’s experiments was a single gene were done by Douglas Coleman. He maintained large colonies of mice and observed by chance (and by paying attention) that some mice in one of his colonies developed a pronounced morbid obesity phenotype, accompanied by hyperglycemia. These obese mice are infertile, but by mating the parents of offspring that developed this obese phenotype he noticed that about 1 in 4 pups developed obesity. Based on this he concluded that he was dealing with a single recessive allele that he named the obese allele (abbreviated as ob).

Around the same time but in a different colony of mice, he discovered animals that also were morbidly obese and diabetic (and could not produce offspring either). These mice too occurred in a frequency of 1 in 4 pups. He concluded that this too was a single recessive allele and he named this allele ‘diabetes’ abbreviated as db.

Based on this information, he then hypothesized that one of these alleles encoded a soluble factor while the other might encode its receptor. In order to test this hypothesis and determine which allele encoded the signal and which the receptor, Coleman carried out the following series of parabiosis experiments, with the following outcomes.

 

 

Assignment: Based on this information, explain in your own words (250 of them or more) how Coleman was able to conclude which allele encoded the signal and which the receptor.

To do so: 1. explain for each of the first three parabiosis experiments (a-c) the outcome that is described and why these experiments all pointed in the same direction. Hint: you can discuss these in any order. 2. Explain the purpose of the parabiosis experiment of the two lean mice in (d). 3. Include in your answer how Coleman was able to easily rule out before doing these parabiosis studies that the ob and db alleles with their highly similar phenotypes were two mutations of the same gene.

Note: Canvas will automatically cross-reference your submission to online sources and a comprehensive database of other papers using Turnitin. This will generate an originality report identifying whether parts of your work match or are similar to any of their sources. The work submitted will be retained as a source document in the Turnitin reference database.
