Speed reading courses are great for business

Categories: Speed Reading.

Sometimes it’s easy to get overwhelmed by the amount of reading that’s required at work, especially when you have reports, memos or training materials to digest. Unlike reading for pleasure, reading at work almost always requires that you not only go through the material thoroughly, along with comprehending and retaining what you’ve read. The material may need to be applied to your job, be interpreted, and become part of the framework of a larger system for which you may be responsible.

Rather than taking a stack of written material home with you to read at night and over weekends, a speed reading course can help you get through the reports or manuals more quickly. Not only do you learn to read faster, you also receive training that helps you remember the content better, often the hardest part of reading stacks of paper. When you read for pleasure, you’re not accountable for what you’ve processed. Work reading, however, is an entirely different situation. Your job depends on a solid interpretation and retention of what you’ve read.

People develop reading skills differently. Some lucky ones retain almost everything they read, which makes reading for work an easy task, but others who are not as verbally oriented, may find the process one of the most difficult assignments that they face. When you learn speed reading, the class gives you an entirely different approach to reading, quite dissimilar to what you learned in grade school.

Taking a speed reading course can involve individual tutoring, group classes or taking the class using DVDs. You can even take the class online using any free time you have when not at work. Although learning to speed read takes a few hours of your time, the payoff will be both immediate and long-term. As you practice the techniques involved with this kind of reading, much less of your time will be required to digest the volumes of information your job may require.

Many fields require extensive reading for the job. Medicine and law have enormous reading requirements and practitioners, whether on the front line or in the back office, are responsible for implementing the material into their practices. Educators spend a good deal of time reading, as do specialists who need to keep up with progress in their fields, like employees in the trades who must continue their educations throughout their careers to maintain their licenses.

Some people consider speed reading one of the most valuable skills they have learned to perform their jobs better and succeed in any kind of work environment. Investing some time in learning this skill can propel you ahead in your career and give you back personal time to spend for leisure activities, which also enhances your performance at work.

Radio vibes

The love and affection between pets and owners goes creates a bond that is second, for most, only to their human relatives and friends. So when a beloved pet goes missing the distress can be a huge upheaval to the owner. Recently listening to a radio show on lost cats you could hear the emotion in so many of the contributors. I imagine should it have been a TV show, instead of a radio program that the images of the owners would have been distressing. They discussed what was the best plan of action should you discover that you have a lost cat. The problem with cats is they say that they say that actually many have second or even third owners who they also visit less frequently than the number one owner. In addition cats have a tendency to curl up in people sheds and garages and then end up being locked in by mistake. Should an investigative mission not come up trumps then poster campaigns are often successful followed by professional search teams, a few which now actually use sniffer dogs. Often the result is positive and the lost cat is found but occasionally cats are just never found. Not the most joyous radio program I have listened to but all the same informative and eye opening.

Dyslexia in pre school children

Dyslexia in preschool age children.

Diagnosing a child yourself with dyslexia at a young age can be quite difficult. It is normal for a preschool age child to reverse letters when learning to write and read. This is why learning and understanding the symptoms is extremely important.
Although mixing up letters and words at this age can be perfectly normal watching the child closely as he or she learns can also be critical. Early diagnosis is extremely important because studies show that if caught early the brain function can be modified so they can become fluent readers.
While mixing up letters at this point in age is normal there are symptoms that one could look for. If the child has no appreciation for nursery rhymes and cannot learn them this could be a cause for concern. If they mispronounce words and have prolonged baby talk this can also be concerning. Another symptom is when the child cannot remember the letters in his or her own name. If the child refuses to read or write there could be a problem. It could be their instinct to just runaway and hide. If some of these symptoms are occurring and there is a family history of reading problems then the child should have a dyslexia test.
While dyslexic children have trouble reading they will be strong in other areas. For example kids that are dyslexic often are very curious and have a great imagination. Figuring things out easy is something found often in dyslexic children. It is important that dealing with being dyslexic does not hurt their self esteem. This is why it is crucial for parents to concentrate on the child’s strengths as well. Teachers as well should be praising their accomplishments often.
Parents and teachers play a crucial role in identifying this disability in children. The earlier it is caught the earlier intervention can begin. Having being diagnosed at an early age is beneficial in the child’s life. If your child shows any of these symptoms and dyslexia is a concern do not hesitate to get them tested. The younger the child the easier it will be for them to learn how to deal with the disability.

Dab Radio

Digital Audio Broadcasting, or DAB, is a digital technology that is designed to broadcast radio stations to a wide audience.

Initial development of DAB technology began in the early 1980s in Germany and first DAB transmissions were made across the country in 1988. Key choices concerning the specifics of the technology to be used were made in 1990 and the complete protocol was finalized in 1993.

The United Kingdom was the first country to adopt DAB as a widespread radio broadcasting system. The first commercial DAB radio receivers went on sale during 1999 and by 2001 there were more than 50 DAB stations being broadcast across London. These first stations were either run by the BBC (British Broadcasting Corporation) or individual commercial ventures.

In 2006, approximately 500 million people worldwide were within coverage of DAB radio broadcasts but sales of DAB receivers were still limited to a handful of European countries. Around 1000 DAB radio stations were in operation around the world at this time.

One of the main objectives of developing DAB radio was to improve the overall sound quality of transmissions by achieving higher fidelity and more resistance to noise and interference.

On many of the early DAB systems however, a better quality of sound can be achieved via the established FM (Frequency Modulation) radio stations due to the relative inefficiency of the audio codec used for DAB broadcasting.

Despite this failure to improve sound quality there are many other benefits inherent to the DBAB system. DAB radio stations are more bandwidth efficient than their analogue counterparts, so more stations can be made available and broadcasting costs are lower.

DAB radio transmitters also have the capability to automatically tune to a particular station chosen from a list, as well as receiving textual information about the broadcast, such as the title of the current song or traffic information for the station.

A newer version of DAB, termed DAB+, was made available in 2006 with the adoption of a new audio codec. This upgrade has the primary goal of achieving greater sound quality for DAB radio transmissions.

Social Network Analysis

Categories: Social Network Analysis.

The aim of Social Network Analysis is to visualise and understand the relationships between people and then act upon these findings. People within the network are referred to as nodes, relationships between people are referred to as ties, while information about the node are node attributes.

Social Network Analysis provides a visualise map of where crucial information and knowledge is flowing within the business. For example, suppose you want to analyse who is talking to who and how frequently this collaboration happens in a research project. Using a social network analysis survey to ask the question “Who do you collaborate with?” across the sample of users will provide you with the data to create the network map. The questions typically use a Likert Scale to gauge how often collaboration occurs:

1. Very Frequently
2. Frequently
3. Occasionally
4. Rarely
5. Very Rarely
6. Never

The data collected from all respondents is then transferred to a matrix. Where people are labelled as nodes and the strength of the relationship between nodes is labelled 1 to 6. This marix can then be analysed using UCINET or NetDraw. Both software programs are typically used for Social Network Analysis and both allow statistical analysis. However, UCINET itself does not visualise the network, NetDraw is bundled within UCINET and provides that capability.

Social Network Analysis is interested in the whole of the network and not just the individual’s ties and links. Taking this holistic view or Systems Engineering approach, allows the structure of the ties and how they interact in terms of strengths (derived from the Likert Scale) to be analysed.

Once you have your social network analysis data then it can be used to visualise the social relationships and identify collaborative groups, cliques of people, areas of poor collaboration and personal networks (ego networks). This information is very powerful and can help to identify where collaboration, knowledge management research and Information Management can help. Powerful knowledge sharing people often bridge networks together and these are called knowledge brokers. When working in teams you would assume that the knowledge broker would be the team leader, but you may also discover that a team members has a wider collaborative network.

Radio Broadcasting

Radio broadcasting is a means of transmitting audio signals via the air as radio waves. These radio waves travel from a transmitter to an antenna and from there are sent to a receiving device to be interpreted.

Radio waves are a form of electromagnetic radiation with a very high frequency. They are invisible to the human eye and sit above infrared waves in the electromagnetic spectrum. They provide a relatively simple and inexpensive way to transmit signals to wide audiences.

Whilst radio stations are commonly known as public systems there are also many stations that exist for non-broadcast purposes, such as base stations used by the emergency services, dispatch stations used by truck and taxi services, amateur radio stations and emergency broadcast systems.

The two primary types of radio station are AM and FM stations.

AM radio stations were the earliest wide-scale broadcasting systems to be developed. AM stations use amplitude modulation to change the radio carrier signal so that it can be interpreted by the listener.

A key advantage of AM radio stations is that the signal being transmitted is relatively unsophisticated, and as such it can be detected and decoded with basic equipment. However, this simple signal is vulnerable to interference by bad weather.

FM radio stations use frequency modulation to alter the radio carrier signal and broadcast a message. FM stations broadcast in the VHF (Very High Frequency) range of airwaves in the frequency range of 88 MHz to 108 MHz.

FM radio was invented in the 1930s by Edwin Armstrong with the sole purpose of solving the interference problems inherent in AM radio. FM radio is almost immune to this interference and has also achieved greater signal clarity by spacing radio stations further apart than AM stations.

The emergence of the Internet has prompted radio stations to broadcast online. Since the 1990s radio stations have been broadcasting on the Internet where they do not suffer from the licensing restrictions applied to other stations, and there is no need to setup air transmission equipment to be able to broadcast to the world.

Radio technology

Radio communication is a widely used form of communication that takes advantages of the characteristics of radio waves to transfer messages across wide distances. Radio messages are sent from a radio transmitter and are received by an antenna which sends them to a receiving device.
The most popular usage of radio communications today is radio broadcasting – an audio broadcasting service widely used by listeners for music and broadcast conversations. Other types of communications sent via radio waves include Morse code, and more recently DAB, or Digital Audio Broadcasting.

The two most common forms of radio broadcast include AM and FM; the two techniques used to broadcast commercial radio stations. Radio waves can also be sent and received via citizens band radio (CB radio) or even transmitted via satellites.

The fundamental idea behind broadcasting radio communications is to transmit a carrier signal which can be received by a correctly tuned receiver and then to vary that carrier signal according to the message you want to send.

AM Radio

A.M. stands for amplitude modulation and was the original method used to broadcast radio stations. It involves changing the amplitude of the carrier signal to send a message. It is a very simple system that does not require a lot of expensive equipment to receive a signal.

AM radio signals are subject to interference by EMI, or Electromagnetic interference. This is most notable to listeners during weather events such as lightning storms.

FM Radio

F.M. stands for frequency modulation and involves varying the frequency of the carrier signal to transmit a signal. This technique is used in the VHF, or “Very High Frequency”, range of airwaves.

FM Radio allows broadcasts to be made with much less interference than AM signals, and by spacing FM stations further apart they are less likely to interfere with each other. The range of an FM broadcast is not as great as an AM broadcast so they are more suitable for local radio stations.
