Chapter13: The problem of Copyright and Fair Use

Copyright Law and Fair Use

This guide addresses issues concerning the use of copyrighted material in an academic setting. Guidelines for protecting works created by faculty and students are available from the library. A separate Web site about copyright and fair use provides extensive additional information, including surveys of primary materials, links to other Internet sites, and an overview of copyright law. Specific advice may be provided by the campus Office of Technology Licensing or the Stanford Legal Office.
What is a copyright?
A copyright is the set of exclusive legal rights authors have over their works for a limited period of time. These rights include copying the works (including parts of the works), making derivative works, distributing the works, and performing the works (this means showing a movie or playing an audio recording, as well as performing a dramatic work). Currently, the author's rights begin when a work is created. A work does not have to bear a copyright notice or be registered to be copyrighted.
Why do we have copyright?
The Constitution of the United States says that its purpose is to promote science and the useful arts. The government believed that those who create an original expression in any medium need protection for their work so they can receive appropriate compensation for their intellectual effort.
What is a work in the public domain?
A work in the public domain can be copied freely by anyone. Such works include those of the U.S. Government and works for which the copyright has expired. Generally, for works created after 1978, the copyright lasts for 70 years beyond the life of the author. Works created before but not published before 1978 have special rules. For works created and first published between 1950 and 1978 the copyright lasts for 95 years. For works created and first published before 1950, the copyright lasts for 28 years but could have been renewed for another 67 years. When planning a project, start by identifying works in the public domain which can be re-purposed in the new work. Request permissions for materials not in the public domain early in the project. If there are images or sounds for which permission to copy cannot be obtained, it is easier to redesign the project at the beginning rather waiting until the project nears completion.
What is fair use?
Fair use provisions of the copyright law allow for limited copying or distribution of published works without the author's permission in some cases. Examples of fair use of copyrighted materials include quotation of excerpts in a review or critique, or copying of a small part of a work by a teacher or student to illustrate a lesson.
How can I tell if my copying is allowed by fair use provisions of the Law?
There are no explicit, predefined, legal specifications of how much and when one can copy, but there are guidelines for fair use. Each case of copying must be evaluated according to four factors:
  1. The purpose and nature of the use. If the copy is used for teaching at a non-profit institution, distributed without charge, and made by a teacher or students acting individually, then the copy is more likely to be considered as fair use. In addition, an interpretation of fair use is more likely if the copy was made spontaneously, for temporary use, not as part of an "anthology" and not as an institutional requirement or suggestion.

  2. The nature of the copyrighted work. For example, an article from a newspaper would be considered differently than a workbook made for instruction. With multimedia material there are different standards and permissions for different media: a digitized photo from a National Geographic, a video clip from Jaws, and an audio selection from Peter Gabriel's CD would be treated differently--the selections are not treated as a equivalent chunks of digital data.

  3. The nature and substantiality of the material used. In general, when other criteria are met, the copying of extracts that are "not substantial in length" when compared to the whole of which they are part may be considered fair use.

  4. The effect of use on the potential market for or value of the work. In general, a work that supplants the normal market is considered an infringement, but a work does not have to have an effect on the market to be an infringement.
How can a work reference the copyright owner of digital photographs, video, or sounds?
Include the copyright symbol and the name of the copyright owner directly on/under/around the digital material. It is virtually impossible to ensure that digital information located at any distance from the image/video would be seen by a user if the copyright notice is not directly attached to the material.
If the material is only used once for a class or a project, does the copyright owner need to be acknowledged?
Images, graphics and video should be credited to their owners/sources just as written material. Also, if you should change your mind and want to use material for commercial purposes, then it is important that you would know where and when you found the material and who is the copyright owner.
Can I download information to my computer?
Digital resources are licensed for the non-profit educational use of Stanford University. Use of these resources is governed by copyright law and individual license agreements. Systematic downloading, distributing, or retaining substantial portions of information is prohibited.

Chapter12: Example of knowledge management

Knowledge Management System


The Knowledge management system is an institutional support to efficiently conduct knowledge management practice like Knowledgecreation, sharing and application.


It provides motivation for knowledge practice.

The evaluation and compensation system is especially to appropriately and correspondingly compensate to organization members for the outcomes from Knowledge contribution activities so that the process is reactivated and maximizes te effect of knowledge management.

Here is an example of KMS (Knowledge Management System) From ENAGE

The Evaluation & Compensation Process


Chapter 11: Information system

An information system and MIS (IS) - or application landscape - is any combination of information technology and people's activities that support operations, management, and decision making. In a very broad sense, the term information system is frequently used to refer to the interaction between people, processes, data, and technology. In this sense, the term is used to refer not only to the information and communication technology (ICT) an organization uses, but also to the way in which people interact with this technology in support of business processes.
Some make a clear distinction between information systems, computer systems, and business processes. Information systems typically include an ICT component but are not purely concerned with ICT, focusing in instead on the end use of information technology. Information systems are also different from business processes. Information systems help to control the performance of business processes.
Alter argues for an information system as a special type of work system. A work system is a system in which humans and/or machines perform work using resources to produce specific products and/or services for customers. An information system is a work system whose activities are devoted to processing (capturing, transmitting, storing, retrieving, manipulating and displaying) information.
As such, information systems inter-relate with data systems on the one hand and activity systems on the other. An information system is a form of communication system in which data represent and are processed as a form of social memory. An information system can also be considered a semi-formal language which supports human decision making and action.
Information systems are the primary focus of study for the information systems discipline and for organisational informatics.

Chapter 10 : Information Technology

The Pros and Cons of Information Technology


Information Technology Pros

1. The world got flexibility
What we think, do or plan must be shared with our co-workers, colleagues and friends. The internet technology has advanced this system to a great extent. The telephone idea (by Alexander Graham Bell) has been modified and made as Cell Phones to increase more flexibility in communication and talk to our dear fellows whenever we require!

2. The sense of responsibility has increased
Let us take ‘Barack Obama- USA President’ as the figure. With the use of networking sites (Twitter and Facebook), blogs, social bookmarking, the leader can approach to the world whenever necessary and we can receive the news and updates which he has done (or wants to be done by us) within a very short period.

3. Easy thinking & evolution in transportation
To think and to research, we need resources to find what our past people has thought, what quotes they have left for us ( information theory). We can find them by a single click in Search engines (specially Google, Yahoo!). By getting a clear cut idea, we get the chance of contributing the world with new technological ideas and inventions and share what we have learnt throughout our lives.
And throughout the ages, it helped us to evolute the transportation strategy which helps us to visit from a place to another by (Roads, highways, air, water and in the skies!)

4. Saves thousand of lives daily
So, by the point heading I hope you understand I am referring towards Medical Sector development. Each day people are getting relief by the perfect use of Medicine, Hospital Technology with addition of (X-Rays, Laser Treatments) and more on the queue. By the combination of the World Health Organization, various fatal diseases can be overcome and just expelled from specified countries by quick plans and ideas.

5. Increase the sense of Human Rights
The technology can remind of our human rights, basic needs and give updates where relief or worldwide help is necessary. During earthquakes, terrible floods, while co-operation is necessary the World Wide Web can help us to collect the donation by a desired amount.
It is not possible to just figure out everything about the good and bad sides of Information and Technology within a page and article as because it has mixed with every aspects and corners of our lives. Rather, let us look at the side effects, bad sides (cons) which IT-sectors have brought to the Human Society.



Information Technology Cons

It has taken away people’s Privacy
As IT-Sectors have wined the people’s heart worldwide. People are here to share and store any kind of information, private date in their hard drives and private online databases. But due to some Cyber-Criminals, nothing is SO Safe both online and offline. If someone becomes a bit careless, s/he may needs to pay high for it. (It’s serious).

The online community is not safe for Family anymore
Children under age may often share Cell Numbers, Private Email Address which can be hacked by people and can pass it to the criminals who have a blue-print to harm the society. And people are loosing credit card privacy and other payment processing options. Again, there are some sites created by Nasty Guys, which can lead under eighteen teenagers to a different path – That Is Going To Bring Harms To The Nation.
It is going to damage a Human’s Natural Power
We can think, gather human principles (ethical knowledge) and make co-operative relationships between friends and families. But due to harmful aspects of (IT) people are becoming fully technological based. And it can bring huge damage to the society as its taking away the natural thoughts and organic ideas.

It can bring World Destruction without Efficient Administration
This is an extra point which I am writing by remembering various Science Fictions. Great scholars have though about the matter wisely. Til now, we (humans) are possessing the leading place in the world and administering the computer technology. But a day MAY come when the technology is going to administer us in all aspects. It may probably happen that we are converted to the slaves of Technology.
So, by this cons I am not trying to tell that Technology is here to bring harms only, because I myself is a technological man who passes 24 hours browsing computer and talking on phones. But as a part of human society we need to give up a look at the both sides of IT.

Chapter 9 : Evalution

characteristic of good websites


What makes a website successful? Keep the following points in mind when creating your website to get the most out of it:

  • Content
Quality content on your website can provide users with the information they are looking for. Content also allows you to establish yourself as an expert in your field. When your website visitors are looking to make a purchase they will feel more comfortable with your products and services if you have built their trust and confidence through what you have written on your website.
Keyword-filled content is also crucial for getting high search engine rankings. Most internet users trust search engines to help them find what they are looking for. Taking the time to create high quality content can have huge payoffs through increased search engine rankings.
  • Simple and Attractive Design
The design of a good website should be simple, yet professional. The design should not take away or distract from the content. Websites with excessive use of Flash and moving images can be very distracting. Use design to help you get your message to visitors, not to distract them from the message. Colors should not be hard on the eyes, and text should be easy to read.
  • Easy Navigation
Navigation and links provide opportunities to incorporate design elements in to the website; however, navigation schemes should not be so elaborate that the user has trouble knowing where to click to move to another page. The average visitor’s attention span is a matter of seconds, and if it is hard to find what he or she is looking for, you will loose that visitor very quickly. Links to your most important pages should be easily found on every page. A good rule of thumb is that every page should be accessible in two clicks from your home page (this may not be possible with larger sites).
  • Unique
The most successful websites will stand out from the crowd. There are a number of was that you can make your website stand out: better design, high quality articles, a blog, a newsletter, some type of resource or tool. Find something that would be appealing to your target market.
  • Fresh
Having a website that changes or is updated frequently will encourage repeat visitors. Repeat visitors will be more loyal and more likely to buy. There are a few different options for keeping your site fresh:
1- Update the site and add content occasionally – This will require you to either pay a designer or do the work yourself.
2 – Use a blog – With a blog you can add content to your website from any computer with an internet connection. All you’ll have to do is login and type. No special software or skills are required.
3 – RSS feeds – With RSS feeds you can add news headlines, weather, stock tickers, etc. to your website. Additionally, you can add content from most blogs to your site with RSS. The benefit of RSS feeds is that once in place they will automatically update.
  • Optimized
A successful website will be search engine-friendly. Optimization includes things like using page titles and meta tags for all of your pages. Using headers and alt tags for images can also help optimization and accessibility. Even a website that is strong in other areas but weak in optimization may be hard for users to find.


Example of good website 





The thinking at Big Think is big indeed. This blog and video site covers, well, the world: arts, business, science, history and much more. Resident big thinkers such as futurist Ray Kurzweil and distinguished guests tackle the topics seriously, and counterintuitive notions and outright heresy are welcome. (One post speculated that there's a 20% chance that we're all part of an elaborate computer simulation from the future.) It's a great place to go to challenge your preconceived notions and recharge your mental batteries.



Three-year-old Airbnb is a sort of eBay for places to stay: a marketplace for spare bedrooms and unused vacation homes in 190 countries that matches travelers with hosts and handles the financial transaction in return for a 3% cut. It's gained a reputation as a more economical, personal alternative to chain hotels, and has inspired countless glowing testimonials. But in July, the site had a p.r. crisis when a host blogged about a nightmarish experience with a destructive, pilfering guest. After a somewhat shaky response, Airbnb responded by instituting a $50,000 insurance plan — and all evidence still suggests that deals gone bad are one in a million

Example of Bias information

This list includes many examples of Bias in Wikipedia, related to homosexuality:

   1. Wikipedia Homosexual agenda by its editors is clearly visible.

   2. The Wikipedia entry for homosexuality is adorned with a rainbow graphic but fails to mention the following: the many diseases associated with homosexuality, the high promiscuity rates of the male homosexual community, the higher incidences of domestic violence among homosexual couples compared to heterosexual couples, the prevalence of murder in the homosexual community, and the substantially higher mental illness and drug usage rates of the homosexuality community. In addition, the Wikipedia article on homosexuality fails to mention that the American Psychiatric Association issued a fact sheet in May of 2000 stating that "..there are no replicated scientific studies supporting a specific biological etiology for homosexuality."

   3. Wikipedia editors regularly and fiercely alter the use of the terms "he" or "she" in articles regarding cross-dressing/transsexual figures. Men attempting to pass as females are near-universally referred to as "she" while women attempting to pass as men are referred to as "he", despite this usage absolutely incorrect in both scientific and legal senses.

Chapter 8 : How do search engines work?

 

  • Internet search engines are web search engines that search and retrieve information on the web. Most of them use crawler indexer architecture. They depend on their crawler modules. Crawlers also referred to as spiders are small programs that browse the web.
  • Crawlers are given an initial set of URLs whose pages they retrieve. They extract the URLs that appear on the crawled pages and give this information to the crawler control module. The crawler module decides which pages to visit next and gives their URLs back to the crawlers.
  • The topics covered by different search engines vary according to the algorithms they use. Some search engines are programmed to search sites on a particular topic while the crawlers in others may be visiting as many sites as possible.
  • The crawl control module may use the link graph of a previous crawl or may use usage patterns to help in its crawling strategy.
  • The indexer module extracts the words form each page it visits and records its URLs. It results into a large lookup table that gives a list of URLs pointing to pages where each word occurs. The table lists those pages, which were covered in the crawling process.
  • A collection analysis module is another important part of the search engine architecture. It creates a utility index. A utility index may provide access to pages of a given length or pages containing a certain number of pictures on them.
  • During the process of crawling and indexing, a search engine stores the pages it retrieves. They are temporarily stored in a page repository. Search engines maintain a cache of pages they visit so that retrieval of already visited pages expedites.
  • The query module of a search engine receives search requests form users in the form of keywords. The ranking module sorts the results.
  • The crawler indexer architecture has many variants. It is modified in the distributed architecture of a search engine. These search engine architectures consist of gatherers and brokers. Gatherers collect indexing information from web servers while the brokers give the indexing mechanism and the query interface. Brokers update indices on the basis of information received from gatherers and other brokers. They can filter information. Many search engines of today use this type of architecture.
