Science Fair Engineering Projects
Human beings have always had the need to move things, build things and adjust the physical characteristics of their environments. Since humanity started gathering in communities and staying rooted in specific geographic areas, these challenges have presented themselves in the daily lives of people. Science fair engineering projects have some of the richest history of any of the subjects covered at these events. The first theories for the subjects addressed by science fair engineering projects date back thousands of years. Some of the greatest minds of history have applied their skills to refining and evolving this particular area of science. Students who choose science fair engineering projects to research are joining these great thinkers in evaluating the needs of humanity.
There are several subcategories to explore with science fair engineering projects. One of the oldest of these subcategories is civil engineering. Students can demonstrate this ancient science in their science fair engineering projects through presentations about the nature of building structures. We all travel over bridges and go into buildings without much thought about the science involved in their construction. Students who choose science fair engineering projects can demonstrate the underlying mechanical principles utilized for construction and safety. Other students may take the approach of automotive engineering in their science fair engineering projects. These students are the ones who will be interested in robotics and other highly technical fields of study.
Science fair engineering projects are also likely to include presentations in the area of chemical engineering. These students have an interest in chemistry as it applies to the creation and adjustment of known elements and interactions at the microscopic levels. Additionally, there will be students who demonstrate science fair engineering projects on the relatively new topic of computer engineering. This field is in its infancy compared to the other fields of engineering. This gives the current students a wide range of opportunity to explore and discovery new uses for the developing field. Many students will also use a combination of these disciplines to create new and innovative ways to use the established principles in order to make new inventions. An example of this combination of principles is the large windmills on turbine farms that are now generating electricity in a carbon free environment.

Podcasting: Everyone is talking about it. But what exactly is it, and how does it work? Simply defined, podcasting is the dissemination of syndicated files, either audio or video in content, over the Web for use on handheld audio/video equipment and computers. The term itself is a combination of two words, “iPod” and “broadcasting.” The word refers to both the file that’s downloaded and the technology to transfer it. Keep in mind that an iPod is not necessary for accessing podcasts. A podcast is also known as an audio subscription service. Listeners can subscribe to and download as many podcasts as they want. As a new method of downloading and transferring information, podcasting is revolutionizing the way we communicate. Podcasts differ from streaming video and audio. Podcasts are usually a continuous series of programs, with many episodes featured in serial format. Podcast subscribers can listen to the content on MP3 players or computers whenever they want. Unlike streaming video, no Internet connection is necessary to review the content of a podcast. But, due to their nature as stored files, podcasts can never be experienced live, in real time – again, unlike streaming video.
Podcasters, or people who create podcasts, have Web sites where their content is available for downloading. Can any old Joe start his own podcast? For better or worse, the answer is yes. All a would-be podcaster has to do is put his files on a web server thats accessible to the public. The file should have an internet address (URI). Podcast files can be any kind of files, from a PDF to a text file. The files can contain audio or video content. The would-be podcaster begins to create a series of files, creating a feed or list of URIs, so the entries in the series can be easily found and downloaded. Each entry is usually accompanied by a date, a title and some kind of content overview. The podcaster links the file to an identifiable place on the web server. This place is usually permanent, and its called the feed URI.
The popularity of these informational feeds has grown astronomically since 2004, when podcasting first became popular among bloggers and software developers. Podcasts cover all sorts of subjects, from technology to politics, to art and literature. Apple made podcasting part of its iTunes package in 2005, and last year, Sony Entertainment released a statement saying that its Play station Portable would be compatible with podcasts.
Now, podcasting has become a part of conventional media. The technology is being used by news stations and newspapers around the world, including The New York Times, The San Francisco Chronicle, the BBC, ABC in Australia, and Sirius satellite radio. The popularity of podcasting is expected to continue to grow, as print media becomes a less vital part of day-to-day communication. Check out New Technology TV for more information.
Advantages and Disadvantages of Software Development Outsourcing
Outsourcing is an arrangement in which one company provides services for another company that could also be or usually have been provided in-house. Nowadays, outsourcing is a trend in a competitive software development and it is expanding all over the world. Software development is very much suitable for the better working of a company. This means that another company is hired to do the task of software development. Outsourcing the software development projects can be advantageous, but sometimes if it is incorrectly executed, it can result to unusable projects. In this article, let’s see some of its advantages and disadvantages.
The advantages of Software Development Outsourcing:
Cost efficiency – companies don’t have to worry about buying expensive software and hardware. Software development technology indulge it. Lower Training cost – it is very expensive thing to give trainings to the new employees. Normally, three or more days are consumed. So, by hiring services from a software outsourcing company, the time and efforts are saved. Time – due to strict time line of some software projects, it is become required to outsource a component of software development projects in order to meet the time demand of the projects. Software companies take credit of immediate pool of skilled developers. Skills – in a situation like software companies outsource, sometimes need a skilled personnel for software development technologies.
The disadvantages of Software Development Outsourcing:
Disappointment – companies can produce code of a poor quality. It involves here who will be the responsible for maintaining the code or project. Need of Constant Management – one of the main reason why projects fail because there is no good manager. A leader who is in constant communication to the clients and also understands the needs or requirements of the clients. Testing is more difficult – generally, testing phase is the most difficult stage in system’s development life cycle. You will undergo more testing cases. If you test a piece of software that was developed in an offshore in-house and find a problem, so there’s a need to communicate to the offshore vendor. This could cause problems because the offshore vendor might not be able to propagate the problem. It could possibly easy to fix the problem if they could see the machine. Or maybe the problem is not properly communicated.
These are the different advantages and disadvantages of software development outsourcing.

Epidemiologists and environmental health researchers have a joint responsibility to acquire scientific knowledge that matters to public health and to apply the knowledge gained in public health practice. We examine the nature and source of these social responsibilities, discuss a debate in the epidemiological literature on roles and responsibilities, and cite approaches to environmental justice as reflective of them. At one level, responsibility refers to accountability, as in being responsible for actions taken. A deeper meaning of responsibility corresponds to commitment to the pursuit and achievement of a valued end
Public health ethics is on the map. In the past year, bioethicists and public health practitioners have begun to focus their critical attention on this complex and understudied topic. Much remains to be done. Childress et al. (2002), for example, describe their account of public health ethics as a rough conceptual map of a terrain with undefined boundaries.
Our focus will be on the responsibilities of epidemiologists, a choice made for several compelling reasons. Epidemiology sits at the center of the science and practice of environmental health, and more generally, at the center of public health. Although it is often referred to as a basic science of public health, epidemiology connects the acquisition of scientific knowledge with its application in preventive interventions, programs, and policies. This connection suggests a fundamental question: What are our responsibilities as epidemiologists? Do we, for example, have a joint responsibility to participate in science and to apply the knowledge gained? This is a key concern for us as researchers, health professionals, and as teachers.
The social responsibility of public health professionals is but one of many concerns in the broader picture of public health ethics. It is nevertheless a central concern. As Ogletree (1996) reminds us, responsibility is a concept particularly well suited to flame many key aspects of the ethics of professions faced with making decisions and taking actions in complex situations. These decisions often involve advanced technologies, high levels of specialization, and overlapping areas of expertise and concern among decision makers from diverse educational, political, and social backgrounds, precisely the situation in contemporary epidemiology and public health. In sum, responsibility organizes many (although not all) of public health’s ethical issues in terms appropriate for professional practitioners.
Responsibility has a deeper meaning as well, corresponding to commitment. To be responsible means to be committed to someone or to some thing. Being responsible in this deeper sense involves a commitment to positive action, to the pursuit and achievement of something of value, such as a social good (Jonas 1984). We will return to the notion of social goods in public health. For now, we want to emphasize that responsibility focuses attention on professional commitments
Finally, our inquiry is intended to assist all public health researchers who seek to define their social responsibilities. For those who are involved primarily in environmental health research, we can think of at least two connected and current topics–environmental justice and community-based participatory research.

A computer is a combination of software and hardware parts, both of which are very much important to the proper running of the system. New computer hardware parts such hard-disks and RAM remain high in price because they continue to improve in capacity and speed, and if one holds onto computer equipment for a long time, then it can become obsolete. There is however a way to buy the same equipment in cheap prices, by purchasing it second-hand.
There are three main methods of purchasing used products:
-Buying directly from dealers and sale brokers: When purchasing used IT Hardware equipment from dealers and brokers, people should use common sense and should follow some basic rules. People should read the license agreement before purchasing the equipment and see whether there is a return/warranty policy. Test everything before purchasing the hardware equipment. Hardware parts such as system RAM, keyboard, mouse and monitor should be rigorously checked before purchasing the product.
-Online dealers: There are many online shopping sites available to buy second hand IT Hardware equipment. Sites like E-Bay, Amazon, OLX, etc are some of the sites where sellers advertise their used products online. If a person wants to sell his used PCs hardware parts separately, such as the hard-disk or RAM, he can do so by registering a new account with any of the above sites. He can then upload his products details and the price he is looking for. The buyers can check the product details and can communicate with the seller through online chat or messaging systems for any clarification, and if the buyer wants to buy the selected product he pays through online payment and will receive the product in the post. Online auctions have become a very popular way for sellers to sell their second hand equipment and earn money at the same time.
-Buying directly from the manufacturer: Manufacturing companies such as Sony and Dell sometimes have a second hand market where they used and refurbished IT hardware products. Mainly these are computer parts which have had some kind of problem and have had to be returned to the manufacturer under the manufacturer warranty. The problem may have been relatively superficial; such as the box being damaged, or a light scratch on the back of a monitor. The manufacturer is not legally allowed to sell the equipment as new, so they must find other ways to offload this problem equipment, sometimes at bargain prices.
For decades now Applied Behavior Analysis has been the method of choice in treating children with autism spectrum disorder. ABA therapy teaches children to think and learn and helps to foster positive behavior without the ineffective method of punishing negative behavior, which does not work in these cases. When first examining and learning about ABA therapy, however, many parents are turned off by the idea that the therapy appears to simple teach children to produce robot like imitations of words or movements. What parents much understand, however, is that treating autism is a process, and that these seemingly robotic responses are critical to helping a child think critically and independently.
One way to better understand how ABA works is to compare it to learning a foreign language. Before you can learn to put together sentences and utilize grammatical structure, you must spend a significant period of time repeating new words. In the beginning your intonations will be little more than robotic repetitions, but as you commit the words and their meanings to memory, you will slowly begin to understand the language, developing the ability to use it and to create sentences and paragraphs and even compose lyrics with it.
Applied Behavior Analysis works much like learning a foreign language. Repeating words and commands and slowly coming to understand their meanings is crucial to learning to think independently and understand broader concepts. While the words for water and sky may be repeatable, it will take an understanding of both of them for the concept of rain to be understandable. For children with an autism spectrum disorder, this type of understanding comes from first practicing repetition until the basic principles are understood.
While many parents fear at first that they are turning their children into robots or teaching them simply to mimic other people, those who have seen or experienced the end result of ABA therapy understand why such repetition is necessary. ABA is designed to help children reach their maximum potential for learning and functioning in society and the classroom, and many children are able to develop a normal or near normal level of functioning with intensive ABA therapy. These results have been proven time and time again, which is why so many parents are willing to take the chance even when they fear they are merely programming their child’s responses.
At the end of the day, repetition with ABA therapy is not at all a way of programming your children to provide robotic responses, but is instead a method of helping them to understand basic language, commands, and concepts. ABA is the groundwork for higher functioning in children with an autism spectrum disorder and is designed to help them prepare to enter typical schools and to function normally alongside their peers. While the methods associated with ABA may seem strange to parents, when it is understood that these children simply need to learn differently, the difference becomes decidedly worthwhile.
