Is the Trucking Industry Ready For 21st Century New Technology?

New technology is making many jobs easier. Is the trucking industry ready for new technology to revolutionize it, as well? Some drivers can't wait for the trucking industry to catch up with other industries by way of technology; but not everyone feels the same way.

Truck drivers around the country welcomed the PrePass System which helps truck drivers by-pass weight stations in 28 of the 50 United States. This system not only helps save time by the truck diver not having to wait in line, it also helps save fuel. According to PrePass, their system has saved well over $1 billion since it began in 1997.

Another new technology that could vastly improve the trucking industry is the development and soon-produced hybrid vehicles. Since diesel costs continue to rise, have an alternative source of fuel is something truck drivers are interested in. However, the newer technology won't be here soon enough to keep some drivers from parking their rigs.

There are currently some environmentally friendly diesel engines, but the cost is such that drivers aren't able to switch over to the new technology. Many drivers would like to purchase new rigs, but it's not cost effective. Until the price of the new engines and trucks drops or the hybrid trucks hit the market it seems the trucking industry is at an impasse.

Other forms of technology are also being implemented in trucks. New anti-lock brakes and collision avoidance technology have greatly affected safety. The biggest changes seen in the trucking industry are not seen directly in the rig itself. Information technology has allowed better communication with drivers and with the trucks themselves. Real-time tracking information is now available.

Truck rigs have undergone technological updates, as well. They are now more ergonomic, the seats as well as the layout of the console, making it much more comfortable for a driver to spend countless hours on the road. The addition of global positioning systems (GPS) has also made the truck driver's life easier.

Transportation is one industry that can't be exported overseas for others to do. It also can't be replaced by technology until someone invents a science fiction transporter system. Truck drivers are a vital part of the United States economy, and while there may be new technologies developed, it's not likely truck driving as a whole will change.

Technology is great, and it can improve our lives, but it won't solve all of our problems. Some of the recent technologies will be implemented in the future. New technologies can become more of a hindrance than a help. Is the trucking industry ready for new technology? For the most part, it seems the industry is ready, but the technology may not come soon enough.

How To Get Into The Field Of Computer Science

Computer science is the combination of theories, applications and principles which brings about the access to information. This science entails studying the mechanization, expression of algorithms and structure, which are systematic processes for solving problems. Computing however, does not always entail computers. Actually, these kinds of problems were present long before computers did, and come nowadays problems can even be solved by manually instead of with a computer. The information which computer scientists discovered, process, store, and convey is regularly programmed into a computer memory in either bytes or bits. Bits help in the transmitting of files between machines, whereas bytes are the most basic units used to measure information and storage. Technology discovers the transmitting of information.

Engineering science started becoming a fast growing discipline in the 1940s as the technological age develops. Scientists think computers are an essential part of the world and a time will come when everyone will have computers. It's a more complicated field than just writing programs or building computers. Computer scientists examine problems to find out if they can be calculated, compare algorithms to determine the best solution, design and create computer systems to perform specifications from research, create encoding languages to convey these algorithms, and apply algorithms to application domains, or sets of software systems which share design features.

Men of science can work within any industry or discipline because computer skills are easily transferred into many areas. Scientists, mathematicians and engineers all use computer science, but those that work in the humanities, medicine, education and law often employ the principles of this science also. Computing science is used also to explain scientific concepts like concepts such as predicting earthquake patterns, understanding theories like the Big Bang and genetics. Computer science is regarding solving problems at its fundamental level. Scientists need to be great analytical thinkers. He/she needs to also have the dedication to continue with something until a precise solution is found. Technology requires the use of reason to assess solutions and revise plans to get the right solution. As finding solutions requires a lot of time, scientists need to have a lot of patience.

Having a major in computing may lead to careers in software engineering, system administration, laboratory development and research and much more. Men of science ordinary tasks consist of creating new user for computers, designing and implementing software, planning and managing technological infrastructures, and developing solutions to computer problems. A computer scientist ability to adjust to new technologies is crucial.

When thinking about a degree in engineering there are dour things to take into consideration: personal level of commitment, education level, requirements for admission, and specialized programs. A degree in computer science is basically offered through the faculty of science, and may be a part of a college or bigger university, or an independent school. The top engineering science degrees are usually obtainable from schools that have a graduate degree program. Schools like these are capable of attracting high-quality faculty and contain devoted assets to this school. There are two kinds of programs available when seeking a computer science degree: university and investigative college. College programs usually last for 2 - 4 years and are focused on a practical skills. However, there are many theoretical courses, but the huge majority of the program is focused on attaining the practical skills needed to succeed in this profession. The university programs are normally for 4 - 5 years. The main focus is on the theoretical understanding and information required to advance in the computing field. While practical skills are taught, the main focus is to offer a holistic view of computer science as a career, and the skill to move in that field.

Choosing the best school must be based on your personal objectives, skill levels, and achievements. A candid evaluation of your high school marks, level of effort and devotion is a strong indication to help you decide which school is the best for you. Choose a school in which you'll be challenged and succeed. An excellent computer science degree program must provide every student with a laptop and have available in majority of their classrooms computer workstations. Engineering is an extremely technological skill which is learned best through practice, discovering new and rising technologies, and exposure to different programs. In these programs the workload is very heavy and requires continued access to computer resources and equipment.

Seek a program which provides the opportunity to specialize in something that you are interested in. This can take in biomechanics, robotics, high-speed computing facilities, or system integration. Search for extra courses, job placement programs, internships and other tools to assist you in getting a job after graduation. You need to have high school courses in technology, English, computers and calculus so as to qualify for admission into a computer science degree program.

New Technologies and Small Business Offer Solutions to Job Losses

Emerging technologies of nanotechnology, biotechnology, information technology and cognitive science can produce a fundamental change in our world. These technologies also offer numerous business opportunities. Unlike conventional technologies, the new technologies are knowledge-oriented rather than equipment oriented.

What knowledge orientation means is that if you have the know-how, or can hire someone with required know-how, you can often start your small business with little investment. For example, if you know how to develop custom business applications, you can start off with an inexpensive computer and a few software tools. Get a client, study the requirements, design a system to meet those requirements, code and test the system, implement it and support it till the client is happy.

You will notice that most of the work involved is brain work, not machine operations or raw materials processing. This is what we mean by knowledge industry. Just like in the information technology example above, the other technologies are also primarily knowledge-intensive.

A Look at the new Technologies

Nanotechnology works with atoms and molecules. You go to these fundamental units of materials and try to modify their structure to create new materials with customized properties. Though knowledge is what you need most, working at nano scale, i.e. at one billionth of a meter, will require expensive and sophisticated equipment like electron microscope (ordinary microscopes won't help you).

Instead of working at these fundamental levels, if you have the know-how, you can get nanoparticles from suppliers and use these to produce a novel product. For example, self-cleaning glass sheets have been developed with a nanoparticle based coating that breaks down dust, which is then washed off the next time some moisture falls on the glass.

Biotechnology works with living organisms such as plants, animals and humans. Though techniques like tissue culture also fall under this definition, modern biotechnology focuses on working with cells and DNA. It is the genes in the DNA that determine the characteristics of the organisms. Modify the genes and you can modify the organism's characteristics.

This technique has been used to develop crop varieties that are resistant to disease and can grow under inhospitable conditions. Genetic therapy can go to the root causes of diseases in humans, unlike conventional therapy that focused on treating symptoms.

Information technology has already created a Google, Amazon and eBay, and numerous obscure but money-making businesses. It was knowledge and ideas, rather than investment in physical facilities, that initiated these ventures. The technology also created opportunities for such services as data recovery and Web content development that smaller players can provide.

Cognitive science is for those who are interested in the functioning of the brain. There are cognitive tutors that sense the way a student is approaching problems, and directs him or her along correct channels. This has the result of making learning more effective. Our brain functions can certainly do with a lot of improvement and a cognitive scientist can use his or her know-how to develop tools that can improve things of the mind.

New Technologies Are also Changing Job Scenarios

The job market is looking for people with new skills. Many community colleges are focusing on training up people with the skills in demand in the current jobs market. Information technology skills, for example, is a favorite field of such retraining.

The more ambitious among you can look at the other technologies if these interest you. There are numerous courses, short-term and of longer duration, that can equip you with specific skills.

Emerging new technologies are thus opening up new avenues both for businesspersons and job seekers.

Master of Science in Information Technology

A Master of Science in Information Technology is a post-graduate degree program that aims to produce skilled professionals armed with knowledge of the core principles underlying computer science and an understanding of emerging industry trends.

Providing an academic base in Information Technology and allied subjects, the MSc. (IT) program aims to transform working professionals into specialists of technology and management. An online MSc. (IT) is open to graduates who would like to gain advanced technical knowledge to be able to combine business analytic with IT. An MSc. (IT) degree not only offers an in depth understanding of basic business applications, it also enhances one's skills that are relevant to a changing IT scenario. An online MSc. in information technology has become popular because it offers an immediate advantage to an existing career.

With this post graduate program one can develop expertise in software development and business applications that have become imperative to organizations across the globe. Subjects under this degree program include communications, programming paradigms, algorithms, network programming and software engineering. An MSc. (IT) degree equips a manager to undertake planning, budgeting, design, integration and deployment of strategic enterprise technologies that have become central to the working of all organizations.

This course has become particularly popular because of the recent demand in the industry for technology management along with people management. Almost turning into a definition of success, this combination is supported well by a master's in information technology. Employment opportunities for computer and information system managers have shown an upward trend with newer applications driving the need for more workers and, therefore, more managers. This degree program not only focuses on information technology, it also promotes business leadership. Therefore, team building, change management, and interpersonal communication make up important curricula of any master's of science in information technology degree.

With an MSc (IT) managers are successfully able to write business strategies, set operational goals and create industrial benchmarks. They have the ability to align IT for better business growth. This inevitably leads to enhancement of the bottom line for any modern-day organization.

This program can assist IT professionals as well as managers from other disciplines to develop on their area of interest. The aim of a master's in science of information technology degree is to create individuals who have sound technical knowledge and are self-motivated enough to progress with the rapid changes that this dynamic field is witnessing.

The Disintermediation of New Technologies

In economics, disintermediation is the removal of intermediaries in a supply chain. Disintermediation is often the result of high market transparency, in that buyers are aware of supply prices direct from the manufacturer. As a result, buyers bypass the middlemen (wholesalers and retailers) in order to buy directly from the manufacturer and thereby pay less. Buyers can alternatively elect to purchase from wholesalers, but most often, a buyer-to-consumer intermediary functions as the bridge between buyer and manufacturer. A few years ago, scholars wrote that the Internet would "disintermediate" industries or eliminate middlemen. Instead, the lower cost of selling over the Net and its immense appeal have produced even more middlemen, which helps explain the success of the search giant Google and the online marketplace eBay.

Technology offers a vast variety of different choices to the end user and the social implications of their adoption create the appropriate atmosphere for people to debate their usefulness and consequences. But whether one is a supporter or an opponent of this technological evolution, the new reality introduced by the adopted technologies surpassed the creators' intentions and emerged into this new "real" world in which relationships evolve, people exchange information, work or even develop themselves as citizens. At the same time, word abbreviations, images, Avatars, icon-bars, virtual reality games or weblogs, are some of the multiple ways with which new technologies have altered the way people interact and have managed to create new subcultures and representations of reality. The adopters of these communication methods relate heavily on the existence and improvement of the used medium, as it must continue to incorporate the advances of other practices and continuously be updated.

Since these recently adopted technology-based practices experience tremendous success, especially among young user groups, their adoption entails opportunities and threats similar to their predecessors. Contemporary technology evangelists support the proliferation of technological innovations, along with the extensive usage of these new types of technologies, ideally by the whole world, in order to satisfy the human quest for interconnectivity and belongingness. On the other hand, opponents of this view suggest that these technological breakthroughs are just another type of "imprisonment" and that will further reduce leisure time, decrease direct face-to-face contact, and will create human "islands."

Evaluating the effects of changing communication forms and the development of additional channels over the recent years, along with how these developments have altered one's understanding about oneself, has been the topic of research in a variety of studies. Human history is full of numerous examples of clash and integration through which a more advanced synthesis was born. Thus, the issue remains not to cease the questioning and the criticism so as to avoid the uncomfortable "battle zone," but rather to use this criticism constructively and examine the new technological evolutions under the scope that they actually constitute the new tools to evaluate the future implications of today's human praxis.

Food Science Technicians - Career, Education & Earning

The profession of food science technicians involves research and development to help improve the qualities of food and beverage products. The job happens to be a highly responsible one.

Monitoring Web Traffic Through Site Analytics

Page Views

You have probably noticed this phrase in online marketing brochures where web sites proudly proclaim the large quantum of visitor traffic they have experienced on their sites. A Page View refers to the total views of every page on your web site. A Unique Page View is a page view by a unique person within a twenty-four hour period. Where as page view counts are site specific, unique page views are visitor specific. Both communicate important information about visitor behavior patterns and provide valuable insights into your search engine ranking.


The reason why there is some confusion about this term is because it emanates from server technology and not from the art and science of visitor tracking and web analytics. A Hit merely refers to the number of information requests received by a hosting server. The number of hits is determined by the number of objects on a page. For example, if your home page has twenty-one objects, your site hosting server will record the page access as twenty-one hits. A word to the wise... It is best to use this statistic cautiously for what it is worth and not to be misled by inflated hit counts when implementing your online marketing plan.

Referrer or Visitor Source

A Referrer or Referring Link also known as the Visitor Source is a page which links to your web site. By looking at your referrers, it is possible to accurately identify the pages from where your site visitors are arriving. Visitors usually arrive from one of these three sources:

o From another web site that has linked to your site

o A search engine results page

o Directly from a browser launch

Referral data is a gold mine of information because it clearly pinpoints the keywords or key phrases being used by searchers to arrive at your web site and the search engines that are sending you the traffic. You can use this data to conduct more targeted and meaningful keyword analysis, refine existing keywords and submit your site to search engines and directories where you are not listed. This data can also be used to further optimize the content of your web pages for improved search engine rankings (SERs).

User Agent

A User Agent is the software that is used by site visitors to access your web site. A User Agent could be a:

o Browser such as Internet Explorer, Mozilla Firefox or Safari

o PHP script pasted on a web page that points to your site

o Search engine spider programmed to index your site

This valuable data can be leveraged to precisely identify the last time a spybot visited your web site to index it. You can also use this data to map traffic trends, spot site abuse and trigger corrective action.

Geographical Location

Many web analytics packages and hosted services provide this information using IP look-up technology. They compile data about the geographical location of site visitors as well as the time of the day during which they visit your web site. You can deploy this data to fine-tune your marketing strategy specially in those regions of the world from where site traffic is below average.
There are still other types of traffic intelligence web analytics systems can provide. They include:

o The length of time a site visitor stayed on your web site

o The URL of the page on which site visitors land and exit your site

o The operating system (Windows XP, Vista etc.) and browser resolution settings on the
monitors of site visitors

Web Analytics and Improved Customer Service

The manner in which you can use web analytics data will depend largely on your site's functionality and its purpose. For instance, if your site has a customer service orientation and provides live chat support for your customers, web analytics data is critical since it will enable you to further tweak the type and nature of your customer service. This key aspect of the overall customer service delivery process is of paramount importance because customer surveys continue to reveal the general level of dissatisfaction among customers regarding the quality of service on Internet e-transaction sites. According to a Harris Interactive survey conducted in August 2007, nine out of ten customers were unhappy with the type of customer service they received when shopping online. The Harris survey polled 2,430 US consumers aged 18 and older and concluded that most online shopping customers were experiencing significant problems when trying to interact with customer service personnel-- a problem that a live chat solution can address and effortlessly remedy.

In the next issue of Live Wire Plus, we will objectively evaluate some of the leading web analytics solutions to help you select the service or product that best meets your needs.

Information in a Box

Web traffic statistics or web stats, as they are commonly referred to, are extremely potent tools used to generate organic data about web site usage. They provide critical information about which web pages on your web site receive maximum traffic. They also generate statistics on the web pages that attract the least amount of site traffic. Site analysis solutions also tell you who is on your site, how long they were on your site, on which page they landed and from where, and finally, from which page they have exited from your web site. Some of the more sophisticated site analytics packages can identify which web browsers are being used by site visitors and which ones should be optimized for improved results. Since these analysis tools compile crucial data on the search engines your visitors are using to arrive on your site and the keywords and key phrases they are typing into search engine search boxes, these tools can go a long way in implementing innovative marketing strategy for your web site or portal. Some can even check for dead links and send error messages.

Science and Technology - Definition by Real Life Examples

How someone could define what is Science and Technology?

Science is search for the profound knowledge. Scientists investigate the world around us. They observe how things work and develop ideas about ways to make them work better. Sometimes they try to test an idea to explain how something works. Scientists perform experiments to find out how things work. The knowledge that they discover is useful for many things. It can help to build new machines. It can help scientists to develop new medicines or cure a disease. Technology is the use of scientific knowledge to create new things.

Then what is an Inventor?

An inventor is a person who creates a new idea or device to perform a task. An invention is the new technology created. An inventor with a new idea or design for an invention may decide to have the idea protected. The idea gets protection from the law in a paper called a patent. A patent prevents other people from making, using, or selling the new idea without permission from the inventor. Some inventions are simply a better way of doing or building something. They may improve an existing technology. Other inventions are much more complicated.

Today's technology has been in the process of development for thousands of years. New inventions are constantly changing how people work and play. They change how people think and live. The future constantly brings us even more changes. This will happen as we continue to learn about the world.

Do we depend on science and technology?

What did you do today? Did you talk on the telephone? Did you ride in a car or on a bus? Did you use a computer or turn on a light? If you did any of these things, you used technology.

Almost everybody uses some form of technology at work, home, or school. Computer programmers use computer technology to write a computer program. People may write letters using a computer program called a word processor. Many people work in the entertainment industry. Camera operators use television and motion-picture cameras. They use them to make TV shows and movies. Disc jockeys, or DJs, play records and CDs on the radio.

Scientists use all sorts of technology to study the Earth and the Universe. Businesses often have telephones, fax machines, and computers. Graphic designers use desktop publishing programs to create books and magazines. Doctors frequently use medical technology. They use it to treat injuries, illnesses, and diseases such as cancer. Pilots fly airplanes and helicopters. Who knows what jobs will be created by new technologies in the future!
