Investigate the two types of sight defect- long-sightedness and short sightedness.

Find the following information:

  1. what causes the defect
  2. the symptoms displayed
  3. propose what sort of lens may be used to correct each vision.

A1. For short-sightedness, the cause is usually because it runs in the family. It can also be an early symptom to show that someone may have type 2 diabetes. The scientific term for Short sightedness Is Myopia. The cause of this is that the light your eye takes in, has its focal point BEFORE the retina which gives a blurred image.

B1. The symptoms are that distant objects appear blurred while ones from short distance are still in focus.

C1. The type of lens that might be used to treat this is A concave lens because it gives a magnified view of a wide area. You can also get Laser eye surgery which is becoming increasingly popular.

A2. Long sightedness is also a condition that can be passed down from genes. Many babies are born with Hyperopia but it corrects itself as they get older.

B2. the symptom is that people cannot see things from a short distance because it is out of focus. This is why people need reading glasses.

C2. The lens that you may need to correct long sightedness is a convex lens because it creates a short focal point. You can also correct it with laser eye surgery

1. What does this video mean/say to you?

Ans: When I see this viedo, I see a person dancing. I see that his spirit brings good spirit to other people who join in the dancing to create a combined effort. A combined effort brings teamwork and friendship.

2. What qusetions does this clip make you think about?

Ans: Who funded the trips to all these countries? Who is the dancing man? Why is he doing this? What does it mean?

3. Why do you think that we are showing this clip now:

Ans: I seriously have no idea. My best guess is that it is to promote a positive side of the world. In everday media accounts you could struggle to find any positive articles. I think we are being showed this clip to show that Media accounts aren’t always negative.

Fibre optic technology offers many advantages when used in medical applications.

a. describe how optical fibre may be used in medical applications

b. identify the traditional medical techniques that optical fibres might replace

c. Evaluate the benefits of fibre optic technology to medicine

A:Optical Fibre’s can be used to help connect a person to the life support machine and also can be used in turning the light on in operation’s.

B:Optical Fibre’s could replace some cable’s for people injury’s or medication by connecting medicine’s and other medicines easily by using one cable.

C:Fibre optic technology would modernize how patient’s are treated because it would be easier to connect medicine to patient’s and it would aslo be easier for patient’s to recieve medicine

How do you feel the media portrays social justice issues?

The media portrays social justice issues in many ways depending on what the social justice issue is about, whether it is a good issue or a bad issue. I feel the media portrays issues sometimes morally or immorally  depending on the issue but in the end the media/journalist just want to sell a story anyway they can.
Has it been difficult to find articles on social justice issues why/why not?

No is hasent because most articles are social justice issues because the effect a large number of people. This means more people would want to read more because it has effected more people.
Do you think that the media operates from a moral framework? Give evidence by using your research.

On somecases yes and on some cases no but mostly their not. The medias job is to sell stories and make money and to do this they paraprhares and streetch the truth. The media does not operate from a moral framework they operate on money.

Open and read the “How to write a critique” document in the resources menu.
Describe what is a critique.

A critique involves identifying critical things to say about an article and resisting the temptation to describe rather than analyse. In hearing that, it fundamentally is just an essay/article that provides a critical evaluation.

wordnet.princeton.edu/perl/webwn
Outline the FOUR stages in a critique.
A critique usually has 4 parts/ satges:

· An introduction (which directs the reader’s attention to the publication and your response to it)

· A summary of the article

· Your analysis or critical commentary on the original text

· Your evaluation or conclusion

Can a critique be positive? Discuss.

From reading the document “How to write a critique” it is evident that a critique can be positive or negative and even mixed. In stage 4(evaluation) of writing a critique it states;

“Is weighing up the positive and negative aspects to decide what value you put on the article”. For this reason, if the positive aspects prevail over the negative aspects, it is assumed the critique is positive.

 Critique the accuracy of the following articles

2 year old donkey called up to pro donkey basketball league.

The story is considered important because the donkey has jumped from fundraising games striaght to the pro donkey basketball league. I think the story is fake and is not really worthy of being on the news and i dont know if it is accurate because it is fake.

The story is about a young donkey who makes it into pro donkey basketball league the reporter is talking about how can the donkey can cope with the presure of being in the pro donkey basketball league.

There are many more weaknesses than strengths in the article because the article is not very important  unless you watch the  pro donkey basketball league which is not real. One weakness is there is no info on the pro basketball league which makes in hard for the reader to know if the league is actually real. It is also very hard to spot any errors because it is not real.

You get no “real” message because its fake and not really accurate because the audience knows nothing about the actual story.

In conclusion the accuracy of the story is not good because the story is fake and has no evidence of the stroy being real.
