Endangered Species




Species: Lear’s Macaw


Type of species: Anodorhynchus leari, a rare Brazilian parrot

Breeding habitsIts: rate of reproduction is 1 to 2 eggs each year during their mating season which occurs from December to May. Not all pairs of birds mate often or at all. These birds reach sexual maturity at around 2 to4 years of age.

Habitat: These birds live in northeastern Brazil. They are also found south of the Amazon River in central and southwestern Brazil, eastern Bolivia, and northeastern Paraguay. It lives in lightly forested areas, swamplands, open savannas, and palm groves, usually near water.

Diet: The nuts of Licuri palm which form a prominent part of its diet. The Lear's Macaws also feed off other fruits found in the area such as pinhao, umbu and mucuma.

Sample food chain:

Why it is endangered: Lear’s Macaw had become endangered due to illegal bird traders, habitat loss caused by human-made fires to clear forest, and goats devouring the birds’ primary food source: licurí palms. In addition, the cows that live near its nesting grounds often stand on the roots of young Licuri palms causing a large loss of food for these birds.

Current conservation efforts: reforestation efforts of the licurí palms are being planned to protect their habitat. All present Lear's Macaw conservation projects are managed under the authority of IBAMA. The Committee For The Conservation And Management Of The Lear's Macaw advises IBAMA on the conservation of the Lear's Macaw. n 1997 the Committee for the Preservation of the Lear's Macaw, {Anodorhynchus lean') was formed. In 1999 this Committee was amalgamated with the Committee of Anodorhynchus hyacinthinus and was renamed "The Committee for the Recovery and Management of the Anodorhynchus lean Lear's Macaw and Anodorhynchus hyacinthinus Hyacinth Macaw", with the objective of continuing the work already started.
In addition in 1997 the FNMA (Fundo Nacional do Meio Ambiente) donated funds, thus enabling various projects to be completed. However, much work remains to be done. It is necessary to maintain in the field one biologist, two trainees and an assistant, together with a means of getting around. This requires a four-wheel drive vehicle, i.e. Toyota and includes maintenance and spare parts. Besides this basic infrastructure various priorities should be established in order to carry out the field study.


What can we do to help conserve them: Establish laws to ban the trading of these birds. Do not buy these birds to keep as pets. Support conservation efforts to protect the birds by spreading the words and donating money to the cause.

Twitter VS Facebook

1.What features are common between Twitter and Facebook?
      Twitter and facebook are social networking Portal.

2.How are they different in term of features?
      Twitter: Twitter is simple, it is  harder to get your arms around at first.
  • Limited functionality; find people, send brief messages, direct replies
  • Limited to 140 characters per update
  • Not all people find it immediately useful
  • Over-emphasis on follower counts
  • Easily abused for spam and increasing the noise level
  • Relatively smaller installed user base
  • As yet no readily apparent monetization strategy
    Facebook:Facebook offers a portal-like interface somewhat reminiscent of Yahoo.Facebook appeals to people looking to reconnect with old friends and family members .
  • Application mashup; find people, make connections, email, instant messaging, image/video sharing, etc.
  • Most people can quickly grasp the value of connecting with friends, family and established contacts; some people report they use Facebook instead of email and IM
  • More emphasis on deep connections with others vs. who has the most connections
  • “True Friends” feature increases your transparency to selected connections; almost like having private and public profiles
  • Huge
  • “gift giving” and personal data collection make Facebook a powerful advertising platform

3.Besides the web. how else can we access Twitter and Facebook?
wi-fi, iphone,itouch.etc.

4.Why do you think twitter and facebook are popular? what are the main selling points?how are they exploited by businesses?
because you can get more immediate responses and it seems to live somewhere between the worlds of email, instant messaging and blogging , it is can use another way to find people and content all over the Net.
Facebook is a great social networking site where people can connect easily with their friends and families. So one main selling point is the great number of users. Businesses exploit facebook to create brand awareness of their products, drive traffic to their website, generate viral effect through word-of-mouth marketing etc


5.What do you personally like about them?
- Ability to connect with lost lost friends
- keep in touch with friends
- share images and videos with friends
- share my updates with friends and family
- play games and quizzes
- be updated about my friends' life

3. Work plan
Feiyi
- Writing the report: 
- Making the video
- Research on Gong Cha
- Visiting Bubble tea shops


Liuxuan
- finding pictures
- Visiting Bubble tea shops


4. About picasa
Picasa is an image organizer and image viewer for organizing and editing digital photos, plus an integrated photo-sharing website.It also has an additional feature for making movies using pictures and texts. Users can conveniently upload the videos on Youtube.


5. Reflection 


list of problems
- Rejected from taking pictures by the Gong Cha shop staff. However, we managed to toke pictures from outside secretly, and when there is a long queue.
- We had difficulty searching for a user-friendly movie-maker. Eventually we found Picasa, which was very easy to use.



语言的影响力

-从这部电影中。你了解到语言带有怎样的威力?

我了解到语言有很大的威力。一句话可以杀死一个人的心。
有一句话叫做“好话一句三冬暖,恶语伤人六月寒”,意思是一句好话可以让他人心情愉快,
但是恶语会让他人心情低落,甚至更严重---会让人心里受伤以至对生活失去信心跟热情。
有的时候,自己最亲的人恶语相向也比自己身体上的
伤更痛,身体上的伤容易好,可是被语言中伤的心灵却难以愈合。


-你认为现今的年轻人是否了解他们所说的话对他人有什么严重影响?何以见得?

我认为有部分年轻人不了解说话对他人造成的影响,不为他人设身处地的着想。
从不经过大脑的考虑就随口说出,或许他们不觉得怎样,但是听的人会感到受伤,心情郁闷。
即使他们事后觉得后悔,可是说出去的话如泼出去的水,有些话听起来很没有威力,但是却会引起轩然大波。
比如说:一个对生活已经失去信心的人,他想寻死,可是他身边的朋友没有劝导他,反而说出一些风凉话,很伤人的话,去刺激他。
因为在他们心里,他们认为他肯定不会寻死,可是那个人听到他们的话心如死灰而造成不可挽回的后果。


-你是否想过改变自己的说话方式 ?为什么?
是,因为我认为有时候情绪激动的时候讲话会不经大脑,缺乏理智,和朋友或者家人闹矛盾的时候会没有分寸,导致伤害别人。
所以,我想学着改变一下自己的说话方式,让自己可以成熟的处理人际关系,即使在情绪不稳定时也可以控制自己,镇静且委婉的表达自己的想法意见。

Differences between prokaryotic and eukaryotic cells

The above shows an Eukaryotic cell. It is called eukaryotic because it possesses a true nucleus. Eukaryotic cells are more complex than prokaryotic cells, and they have evolved from a prokaryote-like predecessor. Eukaryotic cells include animal cell, plant cells, fungi and protists cells. On the other hand, Prokaryotic cells have no nucleus, as shown below.

Prokaryotic cells include bacterial cells. There are several differences between prokaryotic and eukaryotic cells. The main difference between prokaryotic and eukaryotic cells is the presence of a membrane-bound nucleus that separate DNA from the rest of the cell.

 
The purpose of the nucleus is to separate the DNA-related functions of the eukaryotic cell from the other activities in the cytoplasm. The ensures greater  efficiency for the different cell activities. However, since the prokaryotic cell is much smaller than the eukaryotic cell, this means that all materials within the cell are relatively close together and so separation of compartments with the membrane-bound nucleus is not necessary.

The table below shows the differences between prokaryotic and eukaryotic cells. 

Prokaryotic cells
Eukaryotic cells

Multicellular

Bigger size > 10micrometers
