Haley Mohler and Jacob Capizzi 4/16/13



For students entering college, choosing a major is a big deal. Most of the time, students have an idea of what they want to do. Other times, students have no clue what they want to do with their future. This is where research comes in handy. Going into college, I knew that I wanted to me in the health-care field. I did not know; however, what specific field I wanted to work in. Under the options of majors, there is a major called health sciences. Other schools might call it pre-med or medical sciences. In the field of health and medical sciences, there is more than meets the eye to the research and theories that create a platform for future learning. I interviewed Amy Reesing, a human development professor who focuses on the development of the physical, cognitive, and socioemotional aspects of life. 
            After interviewing Amy Reesing, a professor in human development, there is a more defined way of studying our selected discipline. Reesing graduated with a degree in studies of human development. After being asked about the continuing debates in the field of health sciences, Reesing focused on brain development. Reesing stated “The field of medical sciences is never black and white, that is the first thing to know and accept when entering this discipline.” We cannot just place a brain in a jar and watch it grow. Even if we did we cannot know why or what growths and what age mean what. Reesing said that the biggest debate is over the importance of brain development within the first three years of age. Some say that it is life-threatening important and critical to create the right stimulation for the brain to grow. Others say that the brain has a quality of plasticity to always be growing, not placing such strong importance on the criticalness of the first three years of development. Reesing agrees with both ends of the argument. Reesing opinion is “I agree that the development of the brain in the first three years of life is extremely important, yet I do think that there is compensation that can be made.” When it comes to the general understanding and knowing of the discipline that Reesing is specifically in, she focuses on how and why people change and remain the same over the span of life. She mentions the three categories of development (cognitive, socioemotional, and physical), and places much importance on their interactions over several years to understand development of the human being. Reesing states that in her discipline, both quantitative and qualitative data are accepted. “Quantitative data including numbers and a wider-range of results are more accepted and used in the health sciences field.”
We also conducted another interview. Recently, I conducted an interview with a woman by the name Michelle Jung, an ASU employee who works in the Motor Behavior field. Throughout the interview I questioned her on many aspects of her discipline in order to see how different her ideas, view points, and research vary from others in the same or similar field. Early on in the interview I as her “What are some of theories or main ideas seen throughout her field”, in which she responded by saying, “The two main theories you would encounter are the Motor Program Theory and the Dynamical Systems Theory.” These both involve how the body produces signals to make other parts of our bodies move. Personally, Michelle comes from a Dynamical Systems back round which is more involved with the effects of the environment on the functions we perform. In order to understand how she comes about her data, I went on to ask her “What kind of evidence is more reliable, qualitative or quantitative?” She quickly, without even a blink, went on to reassure me that the field she is involved with relies heavily on quantitative data by informing me, “Any type of research done in the field relies heavily on numerical data because it provides the best type of evidence.” As the interview progressed and we became more comfortable with each other was given the opportunity to ask, “Have you come across any gaps in your field of study?” Granted this was slightly more personal than previous questions I had asked, but she had no problem explaining to me about the constant gaps in research she has come across in the past. Moreover, I asked her to provide me with an example in which she had no problem doing as she went on to explain to me, “[She] conducted a lab where she tested postural stability, but instead of testing it from the ankles she measured the posture from the torso and the results were nearly the same as those from the ankles.” This is a fantastic example of how she tests the gap to see whether or not more can be done then what already has been. Overall, the interview went extremely smooth and lasted close to twenty minutes and I am extremely happy I was given the chance to meet her because she was able to give me some different views not only in her field but my field of study as well.
    Each field at any university will have specific research articles for their discipline. After finding a couple articles from the discipline of health and medical sciences and comparing them to those of other disciplines articles, there are distinct differences that set my major and discipline apart from others. In the first article that was analyzed, the research was focused on the composition of the tendons in our body. Titled “Collagen Structure of Tendon Relates to Function” this article claims that the collagen cells located in tendons are formed a specific way to aid in the function of the tendons. According to Toulmins way of analyzing research, this claim has other aspects. The data collected from the article states that under microscopic view, cells of the tendon appear to be in zigzag or crinkled in appearance. The author states “At a first stage of tendon stretching, with very slow forces, a flattening of tendon crimps may occur. Increasing the stretching, but still at small strains, a straightening of molecular kinks of collagen fibrils may happen. Finally, higher strains lead to molecular gliding within the fibril structure.” This leads us to conclude that the warrant of this article is that tendons are capable of more stretching due to the composition of the collagen cells that form the tendon. Backing of this article includes microscopic examinations as well as cell samples and physical observations. There is a reservation that qualifies for this article as well, it is shown that although tendons are more easily stretched because of their unique collagen cells, stretching of tendons vary form one individual to another. The qualifier is that tendons are structures that attach bone to muscle and require an ability to stretch more than other collagen structures, thus they have specialized cells that allow more stretching. In the interviews, it was stated that quantative data is more broadly used in this discipline. The article supports this by creating a range of experiments that slightly differ in their observations to allow a wider range of information gathered instead of one large experiment. This increased knowledge of the research done in this discipline because it was entirely based on science. In other disciplines articles, they may have an experiment included in their article, yet for the health sciences discipline, the experiment is the article. It goes into more depth than a side experiment included in other articles.
            In the next article analyzed, using Toulmin’s argument model, titled “Cell Adhesion and Spreading Factor” it was easy to identify the claims, warrants, and backing to make this article easy to follow. When connecting this article to the types of claims that are normally seen in the discipline health and life sciences, there are multiple instances in which quantitative data is collect to help back the claims made in “Cell Adhesion and Spreading Factor.” For example, this article made a claim that the fetal calf serum (FCS) factor required for both the specific adhesion and spreading of baby hamster kidney (BHK) cells has been purified 140-fold. The purified factor is a mixture which appears to contain two active globular glycoprotein components. This claim, according to Toulmin’s argument model has other aspects that need to be addressed as such as data collected, warrant, and sensible backing which the author of the article addresses soon after. For instance, the larger globular glycoprotein component has a sedimentation coefficient of 12.5S and contains polypeptide chains of about 215 000 D and the smaller globular glycoprotein components is 9S and contains popypeptide chains of 94 000, 80 000 and 71 000 D. This is an excellent example of quantitative data, which my interviewee Michelle Jung stated “Is the most credible data in this field because it provides the viewer with first hand evidence instead of qualitative data.” Being able to bring information into your writing that is credible is single handedly one of the most important things for a writer to attempt, otherwise he would be writing for no one. After continuing to read this article it is easy to spot other aspects of Toulmin’s argument model such as a warrant, backing, and more research to help solidify the articles credibility. “The mixed factor has been determined to have an isoelectric point of 4.0 and its amino acid and carbohydrate composition have been determined,” is the warrant made by the author in this article. This article helps me understand how arguments are typically made in my discipline by showing me the type of warrants, claims, and data that is reputable in this field. Not only does is provide me with great examples of what type of data is more credible, but it also provides me with one way to analyze the data I collect when conducting experiments which is extremely beneficial. As the article slowly begins to end it provides us with backing to help as shown, activity of the mixed factor requires its adsorption onto the substratum surface and about 0.6-0.85 μg of adsorbed factor protein on a 9.6 cm2 surface is required for complete cell adhesion and spreading to subsequently occur. By doing so it increases the credibility, but it also gives information to help identify any unanswered questions that were left. This is crucial when analyzing information in the medical field because the more quantitative data or reputable data inputted into the paper, the more believable the article is, whether is on a subject as simple as breaking a bone or as complex as cell adhesion. Finally the author provides us with a reservation which goes as shown, “The mixed factor adsorbs preferentially to the substratum in the presence of a high excess of BSA and promotes increased cell adhesion and spreading as the density of the factor on the substratum is increased.” When making a reservation it is important to explain how the experiment went, what happen, and what you suspect will happen if someone else tries to conduct the same or similar experiment. This will be seen often in my discipline because duplication of experiments is happening every day. When using the Toulmin’s argument model it adds plenty of depth to your writing and can change the way people view your writing.

4/10 In class blog

1     What is the argument’s purpose in your article? (Is it an argument: to inform, to convince, to persuade, to explore, to make decisions? It can be more than one of these.) What does it hope to achieve?                                                                                                                                The fetal calf serum (FCS) factor required for both the specific adhesion and spreading of baby hamster kidney (BHK) cells has been purified 140-fold. The purified factor is a mixture which appears to contain two active globular glycoprotein components.
2      What types of evidence are used? Highlight/underline different forms of evidence used. (Types of evidence: Firsthand evidence and research includes observations, interviews, surveys and questionnaires, experiments, and personal experience; secondhand evidence includes library sources, films, photographs – anything beyond yourself.)                                                                                                                             The larger has a sedimentation coefficient of 12.5S and contains polypeptide chains of about 215 000 D and the smaller is 9S and contains popypeptide chains of 94 000, 80 000 and 71 000 D.
3      What is the claim of the argument? What is the article arguing? How do they introduce that claim?                                                                                                                                                            Non-specific cell adhesion (i.e., direct adsorption of cells onto the substratum in the absence of serum) can be completely blocked by pre-coating the substratum with bovine serum albumin (BSA); the purified factor can be shown to compete with BSA for the limited number of potential adsorption sites on the substratum surface. They introduce this idea by providing information about Cell adhesion and proposed how and what they would be using to do so.
4.      What assumptions does the author make? Every argument contains an assumption that is crucial to its validity. The assumption, sometimes stated sometimes left unstated, lies between the claim and support, connecting the two with logic. For example, a claim the authors of They Say/I Say make is that “The authors you summarize at the college level seldom simply ‘say’ or ‘discuss’ things; they ‘urge,’ ‘emphasize,’ and ‘complain about’ them.” They then go on to give the following illustration: [claim] … The Declaration of Independence doesn’t just talk about the treatment of the colonies by the British; it protests against it” [support] (38). What then is the assumption? That the colonists had had it with British rule, they were done talking about the issue, and were readying to revolt. Saying that the colonists wrote the Declaration of Independence to tell England how they felt doesn’t accurately express what the colonists intended.                                                                                             The purified factor is a mixture which appears to contain two active globular glycoprotein components. Activity of the mixed factor requires its adsorption onto the substratum surface and about 0.6-0.85 μg of adsorbed factor protein on a 9.6 cm2 surface is required for complete cell adhesion and spreading to subsequently occur.

*interview #2 summary

Part 2:

*discuss counter arguments
*conclusion

Chapter 10 response:
After reading Chapter Ten, I’m convinced that some of the claims the author was speaking of throughout chapter 10 will be seen throughout Wp3. By doing so, it will add copious amounts of details to our writing and give our discipline depth in our writing. Also, the interviews will bring more depth to our paper by providing hard evidence for our audience. This is extremely important because it amplifies the claims one makes throughout his or her writing. After reading chapter ten it gave me an eye opener after realizing how important adding details and making claims is to one’s writing.

In class 4/3

Monty Python and the Holy Grail
Claim: The woman is a witch
Data: She looks like one, and weighs the same as the duck
Warrant: If she looks like one and weighs the same as a duck, then she is a witch
Backing: witches are made of wood and float, so if she weighs the same on the scale as a duck than she will be determined a witch
Reservation: They faked her looking like a witch
Qualifier: If a woman is a witch than she should be burned to death because witches are bad

[The three-dimensional ultrastructure of the collagen fibers, reticular fibers and elastic fibers: a review].


Claim:Fibrous components of the connective tissue are light-microscopically classified into three types: collagen fibers, reticular fibers and elastic fibers.
Data:The collagen fibers are shaped like tapes or cords about 1 to 20 microns in diameter. Each fiber is a bundle of fibrils running roughly parallel to each other.
Warrant:These fibers are considered to play an important role not only in adhering the cells to the collagen fibers, but also in constituting the skeletal framework suitable for individual cells and tissues.
Backing:The elastic fibers consist of two different components: elastin and fibrillin.
Resevation: Elastin forms unit fibrils of 0.1-0.2 micron thickness which are arranged in bundles or laminae specific to individual organs and tissues.
Qualifier:For a comprehensive understanding of the fibrous components in the connective tissue, the author proposed categorizing them into two systems: the collagen fibrillar system as a supporting framework of tissues and cells, and the fibrillin-elastin fibrillar system for distributing stressing forces uniformly in tissues.

Collagen structure of tendon relates to function.


CLAIM: a tendon is a tough band of fibrous connective tissue that binds muscle to bone, and have crimps in the cells that allow extra stretching
