Talk:2011 Group 4 Project
Hi guys, someone accidentally edited the template at the bottom of the project page instead of editing your project page so your group sub headings were on everyones project page instead of just yours. when you edit a page, make sure you are editing your group project page, it is really easy to edit another page without realising it. (ive done that before too). Ive fixed it for you :) Hope this makes sense :) -Jill (group 6)

Post Peer Assessment Discussion
Hey guys in response to the peers i moved around my pictures, gave them text under them, and added a lot of new information and some photos to the structure section. the only issue we have left is to clean up our reference list since it mostly looks like a bunch of pubmed IDs. i guess we will ask mark what to do with this.--Michael Orenstein 21:48, 25 May 2011 (EST)
- This is the week before the mid-session break.
- In the lab this week we will have an opportunity to discuss any issues which are slowing progress on your project.
- The Thursday of the week beginning 02 May will be when all projects will be open to Peer Assessment.
- What you have on your page by Thursday of that week will be the content that others in the class will comment upon.
- I see many groups now have subsection titles for their projects.
- Here are some searches: Pubmed search all databases junction | PLoS junction | JCB junction You can now simply put your own search term into each top window.
- Now's the time to get your images, movies, media etc uploaded. Biomed central | JCB | JCB Archive | PLoS. Once uploaded you can make a gallery on either your project or discussion page using <gallery>File:name here</gallery> tags with your image files listed between the tags. When you upload project images, add this text as it appears replacing # with your own Group number to the summary information [[Category:2011Project#]].
- Shown below are the criteria that will be used to assess your final project.
Group Assessment Criteria
- The key points relating to the topic that your group was allocated are clearly described.
- The choice of content, headings and sub-headings, diagrams, tables, graphs show a good understanding of the topic area.
- Content is correctly cited and referenced.
- The wiki has an element of teaching at a peer level using the student’s own innovative diagrams, tables or figures and/or using interesting examples or explanations.
- Evidence of significant research relating to basic and applied sciences that goes beyond the formal teaching activities.
- Relates the topics and content of the Wiki entry to learning aims of cell biology.
- Clearly reflects on editing/feedback from group peers and articulates how the Wiki could be improved (or not) based on peer comments/feedback. Demonstrates an ability to review own work when criticised in an open edited wiki format. Reflects on what was learned from the process of editing a peer’s wiki.
- Evaluates own performance and that of group peers to give a rounded summary of this wiki process in terms of group effort and achievement.
- The content of the wiki should demonstrate to the reader that your group has researched adequately on this topic and covered the key areas necessary to inform your peers in their learning.
- Develops and edits the wiki entries in accordance with this sites wiki guidelines.
By Week 5
Each Group member has added to the discussion page:
- A Review Article
- A Historic Research Article
- A Current Research Article
No two students should add the same paper and there should be a link to the original article.
--Mark Hill 14:17, 20 April 2011 (EST) Looking at your discussion page there appears to be group members not actively contributing to the work. I remind all group members that your final mark will also be based upon your contribution to the project during its development phase.
--Mark Hill 17:14, 30 March 2011 (EST) OK Group 4, Just one student (Z3288729) trying to organise an online discussion to date and no content added by any other group member to either your discussion or project page. Also no response to Z3288729 request about the project topic. You were meant to have already begun looking into both the topic and references, pasting links on your discussion page. I will see you in the lab tomorrow to discuss whether you are having problems or are simply not doing the work. This search should get you started. Search Pubmed: Desmosome
who deleted some of the subheadings from our page??? is it not important to talk about hemidesmosomes and related abnormalities?? please explain why you are deleting things before you do it. the rest of the group is only going to get confused! --Sarah Jenkins 09:10, 15 April 2011 (EST)
== WEEK 6-7: I have set up some subheadings on our project page. We really need to get a move on and start some writing soon if it is possible. I think we may even have to meet up to discuss how our group work is going===--Sarah Jenkins 11:07, 10 April 2011 (EST)
It looks like everyone has found some articles, so would it now be possible to start the writing process this weekend? We dont need alot here but it would be good to start bringing our ideas together --Sarah Jenkins 10:47, 6 April 2011 (EST)
do we write straight to the other main page? z31--User:Z31 19:29, 10 April 2011 (EST)
Yes, it is probably easier that way as this page looks like a disaster at the moment. Just make sure that everything is also properly referenced. --Sarah Jenkins 17:10, 12 April 2011 (EST)
Firstly, is everybody happy with the topic that was decided upon last week? Next, we need to divide ourselves into sections of the topic. What if we divided it into:
Structure and function
Current research methods
Current and future possibilities for research
I personally would be most interested in researching the related abnormalities.\
(z3217345) M.B (Preference for structure and function)
(z3289066) E.K current research methods is good
I think that we need to go into a lot more detail with the layout and division of work between us. If anyone could help with this it would be much appreciated. We could possibly look into how they were first discovered also? I had a quick look at function, and there is HEAPS. This should become a separate subject area. With structure, we could look into location within the cell as well? Hemidesmosomes needs to be addressed, not in a huge amount of detail but it cannot be ignored. --Sarah Jenkins 11:01, 30 March 2011 (EST)
Since there won't be much information about current research methods, I'm happy to do hemidesmosomes as well.--Elisabeth Karsten 11:04, 30 March 2011 (EST)
Great. I was thinking that we shouldn't have way too much on related abnormalities, so I can work on the structure as well?? And then leave function to Z3217345 --Sarah Jenkins 11:07, 30 March 2011 (EST)
I am happy to take on the role of team manager if everyone thinks im up to it? I agree that we do need some authority and I like the idea of all of us working on each section before moving on to the next one. --Sarah Jenkins 08:52, 31 March 2011 (EST)

Desmosomes are the binding site for intermediate filaments, which connect adjacent cells. They are composed of cadherin molecules, proteins that assist in moderating Ca2+ dependent binding in eukaryotic tissue. There are two types of desmosome cadherins: desmogleins (DSGs) and desmocol- lins (DSCs). These molecules are homophilic, which contributes to the specificity of the binding site of desmosomes.
Current research methods
Current and future possibilities for research
Sarahs idea of z31 (me) doing function alright? So i cover ongoing/ future research and function?
Perhaps a collaboration of everyone for every topic, in that everyone submits the key pointers they think the allocated person for that topic should cover.. might lead to a more fluid overall project . I propose we elect a project manager, whom we all argue our cases to of how the project is being directed.
In terms of what a desmosome is and what it does maybe every team member will want a say on how this is portrayed. The project manager can then decide the best possible final content. One person kicks off structure and somebody does function, then individual team members forwards suggestions regarding improvements/ detractions to the project manager . Then the next topic is done. In sequence...might get the project done faster this way.
In this way every topic will become of the group mind. I've read some of the other previous projects and sometimes it looks like four individual projects stapled together.
So someone writes the structure - then we all submit our input to project manager
" ' writes the function - then we all ======================
In this way we know what is being previously said and can follow on....this will be particularly important for the current / ongoing research sections that might become bottle necked here.
The writer of the topic can confer with the group on the discussion page as to what they are writing as they are doing it.
If the writer of the topic disagrees with other group member's ideas the group manager will make a final decision based on a vote.
i dont think it matters who is the group manager but perhaps Sarah is the one for that job (Agree/ Disagree?)
I forward this proposal to the elected project manager and/ or for the group to vote on.
TOPIC BREAKDOWN: Amendment A.
((please comment on ideas of what should be discussed in each topic to give the writer a structure to work with)).
These are my ideas:
1) z3217345 writer: Introduction-Importance of the desmosome in cell biology/who first described the existence of a desmosome? inherited mutations in families first seen / basic necessity of good desmosome function-very brief short description of pathological desmosome function /Structure: location/ histological description/ Em micrographs/ a hand drawn diagram. location of / microscopic appearance which stains are used
2) histological function will be here
3 )z3288729 writer: / abnormalities seen (introduced histologically) factors leading to desmosome pathology is it nutrition based or inherited
4) z3289066 writer: (abnormalities pathology((impact on humans)) leading onto) current research (aims of research/ successes of) what clinical manifestations or symptoms are experienced- the human impact what has research done about it so far
2)+5) z3129413 writer: Histological description of function -introduce the original investigations into desmosome function/ the researchers / due to its structure what is a desmosomes main function includes schematic diagrams and Where research still needs to be done/ any existing problems ( main future investigations of note ). Some sort of conclusion.
writers of topics 1 and 2 will probably have to confer on content.
My name is Sayanthan (Sai) or z3252635 and I'm really sorry I haven't actually said or put up anything on this page. I've read through everything and I'm sort of lost so I was wondering if we could go through the plan in class tommorrow. I've also done a bit of reading up on our topic just background information and sorts so I know what we are talking about. Here are the links i used
