A New Form of communication

Blogs

The term Blog is a contraction of Web-log. A blog is a web message. Blogs are arranged in reverse cronological order in a website. A common form of a blog website is a personal diary or online journal. Besider personal blogs there are:

Blogging reached its peak in growth rate in 1999 and was consider mainstream in 2004. Over the past 3.5 years the number of people blogging and doubled every 6 months. The phenomonon has peaked and is consolidating. Americans are writing less online journals.

There is now a miniblogging form promoted by the software package Twitter.

A list of social networking sites. As you can see by the list there is a wide range of social networking sites organized by groups, countries, or topics. The membership of Facebook and MySpace now is over 200M, but there are tiny sites with few members.

Let us consider the services Facebook offers:

Some other networking sites:

 

How do they make money: The more members a site has the more money it makes in advertizing. Facebook makes money through gifts, its marketplace, and by allowing 3rd parties to create applications on Facebook. Appaholic.com rates these application.

 

Security

With vast amounts of personal and corporate information in databases being transmitted through communication systems, there is a pressing need for security in computer-communication systems. However, the more secure you make a computer-communication system from access by hackers, the harder access becomes for legitimate users. Computer-communication systems can never be made completely secure against unauthorized users. Military style encryption, the translation of computer-communication information into code, is a current trend in computing and communication. Is all information being used by computers or communicated between people or machines going to be encrypted?

Currently, there is a major battle between police organizations and businesses concerning cryptography. The National Security Administration and the FBI want to be able to tap into any communications (with a warrant, of course) for the purpose of catching criminals. They propose a cryptography system developed by the NSA called a Clipper chip. Computer experts are opposed because they believe the NSA has a backdoor to easily listen to any communication message. Also, organized crime would have the resources to break such a system and steal bank transfers. Businesses generally want unlimited encryption to protect vital corporate secrets. Recently the Clinton administration rejected the NSA encryption scheme.

Efficiency versus privacy

Increasingly, many kinds of decisions will be made by analyzing alternatives using databases. This will include personal decisions as well as political-economic decisions. Man, as a decision maker, has limited cognitive skills. This limit has been called bounded rationality by the Nobel laureate H. Simon. Using decision aids humans can make better decisions in all aspects of life. Making computer aided decisions requires relevant databases. This raises a fundamental conflict between privacy and property rights versus the data needed for making better decisions. Computer based decisions make the information structure or what information should be available for each type of decision a fundamental policy issue. For example, credit data bases enable stores to determine a consumer's credit rating quickly at low cost. This is the basis for the credit oriented consumer market. Without such databases it would be much more difficult to obtain auto and home loans.

Communications versus transportation

With the channel capacity expansion of the communication system, the cost of transmitting a bit of a message will fall at a rapid rate. Types of communication requiring higher baud (bits per second) rate, for example, video, will gradually become more commonplace. Technological advances may decrease the cost of transportation, but not nearly as much as technological advances will decrease the cost of communication. Thus, one would expect a substitution of communication for travel. Modern society is organized around the automobile. Most people live within a 20 minute commute from work. This means the auto transportation system is built to handle the peak morning and evening traffic loads. During the rest of the day, the system has considerable wasted idle capacity. Moreover, autos are one of the principal sources of pollution. In areas such as Denver and LA inversion layers create social costs in the form health problems in the respiratory system. Also, communication requires much less energy than transportation. For these reasons, society would be better off with less commuting.

Prior to the first industrial revolution, most people worked out of their homes. In industries such as cloth manufacturing, the merchant took raw wool to farmers' cottages to be spun into thread. Then the merchant picked up the thread and took it to the weavers cottage to be woven into cloth. The merchant then took the cloth to another cottage to be dyed. Work was brought to the home and artisans generally had their homes attached to their shops. The custom of commuting to work began very recently. As automation of manufacturing proceeds, work will increasingly involve the manipulation of informational objects. As the manipulation takes place through a terminal, the substitution of communication for travel depends on how effective groups can be at accomplishing tasks through communication networks.

Experiments in problem solving

How we physically locate people in an organization for effective problem solving requires experiments to find out how people communicate in problem solving. Currently in large organizations there is much decentralization in location. The issue is: Given all our new communication/computing equipment, what activities can be accomplished effectively remotely?

In one experiment, two groups in separate rooms were tested in the speed at which they could solve simple problems:

i. Assembly of a trash can carrier when one group had the parts and the other the instructions.

ii. Find all the citations relevant to an article when one group has the article and the other the index.

iii. Find the closest physician when one group has the address and the map while the other group has the list of physicians.

The two groups could communicate:

i. Communication rich: voice and video.

Ii Voice.

Iii Hand written messages.

iv. Typing: inexperienced.

v. Typing: experienced.

The results indicated that to solve problems:

Some business research indicates that effective interactions can take place with a meeting and subsequent phone conversations. This raises the issue of what type of human interactions need to be face to face in institutions for effective institutional performance.

Recently, researchers have been investigating how groups solve problems in computer networks when the identity of the messenger is not revealed. This totally changes the behavior from a face to face meeting where everyone knows who is speaking. In a face to face meeting the hierarchy of status determines who speaks and how much. A network problem solving session is much more democratic with much greater interaction.

 

Teleconferencing

There are many types of teleconferencing. The oldest, simplest, and cheapest type of teleconferencing is a conference phone call. Advances in teleconferencing are proceeding in two directions. One approach is in teleconferencing taking place in special teleconferencing rooms or with special equipment and the other is in teleconferencing in computer networks via desktop computers.

Let us first consider special teleconferencing rooms or equipment. In this approach a more advanced type is voice and slides, and the most advanced type is video teleconferencing with dynamic video, voice, and data. In 1982, ARCO spent $20M for a teleconferencing system because the chairman traveled 600 to 700 miles everyday for the past 35 years. ARCO's system includes one TV screen for pictures and one for data (Alaska to LA) and they also plan to expand network and transmit data from seismic tests. Video teleconferencing is growing at 20 to 40% a year. With increased long distance communication competition through the creation of fiber optic networks with tremendous excess capacity rates should continue a downward trend. As the demand for teleconferencing services increases, producers obtain economies of scale in production. For example, to reduce the cost of full video conferences, one company has set up a video conference 'coop' to sell the unused time at facilities set up by corporations. Later, Aetna set up video conference rooms to link its corporate center with its data processing center which were 15 miles away. It cost $250,000 to build and cost $250/hr to operate. Before Aetna set up this system, 500 programmers met 3000 times a month with managers in the headquarters. Aetna has installed video conference rooms in its Chicago, San Francisco and Dallas offices. By 1986, a typical video conference rooms center cost more than $200,000. A year later the cost fell to $120,000 and by 1989 to $60,000. The cost is projected to be below $15,000 by the end of 1993. At the same time the cost of phone lines for video conference rooms has fallen from $1600 to less than $20 per hour.

A form of teleconferencing in computer networks is called collaborative computing. Lotus Notes is an example of software which allows groups to work together. You should in the next few years expect a large number of software packages which allow groups of people at remote personal computer locations to exchange text, data and still images. PC manufacturers are now creating PCs which incorporate a videocam for videoconferencing through computer networks. Such videoconferencing will become commonplace in LANs before WANs. This may not become commonplace in WANs until the capacity of the phone system expands to cheaply handle desktop videoconferencing.

Low cost video teleconferencing offers businesses many advantages. Teleconferences generally can be set much more quickly than business meetings involving people at large distances. In addition, teleconferencing is cheaper than travel. Moreover, executives are more effective not having to work in airplanes and hotel rooms. A success story with teleconferencing is M/A Com. Teleconferencing is used to manage 26 companies. Teleconferencing links small office in Boca Raton, Fla to four M/A Con centers in San Diego,CA; Catawba, N.C.; Germantown, MD; and Burlington, MA. The company is also a vendor of teleconferencing systems that make use of its satellite link. Instead of two to three days to arrange cross country meetings, thirty minutes is required to arrange teleconference meetings. What this means is that M/A Con can respond very quickly to changing market conditions. Yes, not all businesses are jumping into teleconferencing. Many will wait until substantial savings have been demonstrated by the leaders.

Various forms of teleconferencing are also being created in computer networks. The simplest is the chat mode of information utilities. More advanced versions of text teleconferencing are in widespread use. One example is the US Army Missile command. Currently, communications companies are creating video teleconferencing systems in computer networks. For example, Northern Telecom has developed the Visit system which is an $3899 addon to a PC or Mac. This system provides a separate window for the image of both parties on both screens delivering 8-14 frames per second. In addition, both participants can bring up a drawing or document in a shared workspace. As multimedia PCs become commonplace video conference rooms will be accomplished with an installed video camera and a board for transmission and reception for less than a thousand.

Forecast: From 2005 to 2010 teleconferencing will explode because of advances in equipment, the desire of firms to reduce travel costs, and the threat of terrorists blowing up airplanes. Teleconferencing technology will integrate:

Microsoft Live Meeting integrates office software with all of the above except video communications. I would expect Microsoft to add video conferencing in a year or two. Two teleconferencing equipment makers, Polycom and Tandberg have equipment for video conferencing rooms and personal computer video communications. Cisco, the maker of routers for the internet also has a meeting technology.

Telecommuting

In the 70's a research group lead by J. Niles demonstrated that by using existing technology, corporations such as insurance companies could decentralize into a group of local offices connected by communications and be just as effective. The major advantage to decentralization is much less distance to commute by workers which results in much less smog.

In London, Mrs. "Steve" Shirley organized F International Ltd., a company where everyone works at home connected through terminals. This software firm does $5M a year business and most of the workers are women with children. Telecommuting enables F International to obtain skilled workers who otherwise would not be able to participate in the workforce.

Telecommuting does not bring positive benefits to all participants. Generally, professionals benefit from telecommuting because they can have a wider choice in lifestyles. For example, a couple of years ago Business Week reported on a partner of a Chicago law firm who telecommuted from Telluride, Colorado. Phone calls were automatically rerouted to Telluride. If he was called before 10am, he could make a business meeting in Chicago that evening. Towns in Colorado are so interested in acquiring telecommuters they are installing better communications to attract them. Compaq made its salespeople telecommute with both corporate and personal success.

In contrast, clerical workers frequently do not benefit from telecommuting. Business managers have used telecommuting as a device to eliminate fringe benefits and place telecommuters on piecework wages for typing and so on. There have been law suits against this practice.

Telecommuting will increase as automation displaces people from manipulating physical objects and the channel capacity of the communication system makes video communication inexpensive. With the TV flat screen which is just coming online currently, you could have a wall with multiscreens for each participant in a conference. Most critics of telecommuting do not perceive the impact of the vast increase in channel capacity. New social customs will evolve for telecommuters, however, this will take time. The cottage workers who did not want to work in the textile factories tried to destroy them. There is generally a tremendous resistance to social change.

The major growth in telecommuting will not be in full time telecommuting but in part time telecommuting. With the rapid advance in wireless communication, notebook computers and other portable electronic gear, individuals can link up with their offices from any location. This means they only have to be in the office for face to face meetings. Corporations are going to promote telecommuting in cities with dirty air because of provisions in the Clean Air Act of 1990. Thirteen cities with dirty air must increase the average number of riders per car from 1.3 to 1.5 to prevent 3.5 million tons of carbon from polluting the air by the year 2000. Telecommuting satisfies the requirement for increasing ridership.

What is fueling the growth of part time and full time telecommuting is the growth of broadband communications, such as DSL and RoadRummer into homes. A current estimate of the number of teleworkers is 20 million. My daughter when she worked for I2 in software sales could pick her home city. She did all her work through her laptop and meet with her sales team at client presentations.

Evolving transnational organizations

As firms learn how to use teleconferencing and telecommuting to increase the effectiveness of groups coordinating their work from remote locatings, groups are being organized on an international scale. Two factors are driving this type of reorganization:

One of the leaders in international group organization is IBM.
