Teacher and Student Relationships in the Age of Social Networking

That education and social media will share borders and encroach on each other's area of influence shouldn't come as a surprise. On one hand, education as we know it is very much a social engagement in itself, involving teachers (the channels of new cognitive experiences) and students (the learners of new or restructured knowledge). On the other hand, social media is both a technological tool for communicating different ideas as well as an enriched environment for collaboration. As such, the benefits that social media can deliver to contemporary education can be very tremendous, indeed. In fact, it is now very easy to imagine a virtual classroom that melds the current platforms of the most innovative online universities with the powerfully engaging and personal experience of social media. How the learning dynamics will be influenced by this theoretical setup is still open to debate but it is a possibility that may now have already taken root in some form or another.

While the exciting, positive advantages of using social media in education is a topic that can rouse a lively discussion, the serious ethical issues that result from their melding inspire a much more heated debate. In July this year, the state of Missouri enacted a law that prohibited students and teachers from being friends or contacts in social networks such as Facebook. However, following a strong clamor from teachers who deemed that their fundamental rights are being assailed by the legislation, the original bill was substantially modified, finally granting individual school districts the freedom to establish their own policies on social networking.

Both sides of the argument have persuasive merits. It is no secret that social networks have become a virtual setting for instigating various crimes ranging from bullying, extortion and sexual assault. That there are people with criminal intent who use social networks to plan and execute their series of capers is clearly undeniable. There are quite a number of disturbing stories about them that we encounter almost every day.

In addition, some psychologists and social scientists believe that taking the conventional student-teacher relationship out of the classroom can lead to dire consequences. When taken to the highly informal environment of most social networks, the traditional authority of teachers can be eroded to the point that classroom engagements will be among peers, not between teachers and students whose roles and expected behavior are clearly defined.

The many possible types of interactions on social networks such as liking a particular hobby, organization or place can also lead to inappropriately close relationships between teachers and students. On top of this, the provision for one-on-one messaging between friends or contacts can even encourage sexual misconduct.

That said, the danger of social media is very real. However, merely focusing on the risks will cause us to miss its true potential as a teaching tool/environment. After all, there's bound to be some criminally-minded people just about anywhere a substantial group of people converge, whether online or not. True, social media lends an anonymity and a cloak of security to criminal elements but there are ways of circumventing, restricting or exposing their schemes without altogether banning the use of social media in education. To do so would unfairly clip the tremendous benefits social media can enrich the learning experience with.

A case in point. A pilot social media program for the 7th grade was conducted in a Portland, Oregon classroom. The results were amazingly conclusive:

1. Schoolwide, 20 percent of all students accomplished and submitted extra assignments even when these assignments carried no bonus credits for them.

2. Grades increased by more than 50%.

3. Chronic absenteeism was reduced by more than 33%, allowing the school organization to meet its absenteeism reduction targets for the first time in its history.

In a nutshell, closer collaboration and easier means to communicate encouraged students to participate more. Meanwhile, the very engaging social media environment enabled the students to perform better.

Banning social media in education will prevent schools, teachers and students from reaping its phenomenal benefits. A few decades ago, the Internet created a very similar educational milestone. Many schools in the nineties were hesitant to implement an Internet connection for fear of unleashing unwanted content from the Web to their student population. However, As Karl Meindhart, the developer of the Portland social media program commented, "There was this thing called the Internet starting to show up that was getting a lot of hype, and the school administration was adamantly against allowing access...The big fear was pornography and predators, some of the same stuff that's there today. And yet...can you imagine a school not connected to the Internet now? "

In yet another display of technology-helping-teaching-become-terrific, the New York Times published a May 2011 article on how a group of English Teachers are leveraging a Twitter-like messaging technology that encouraged 11th grade students to freely communicate their ideas on different subjects, something that might just remain unvoiced without the new technology. Instead of verbally expressing their opinions about a poem, for example, the students and teachers collaborate and conduct discussions using the messaging tool that makes it easy for everyone--even those who have the unreasonable but socially common fear of speaking in front of people--to freely share their opinions. To all the teachers who conducted the experiment, social media tools such as group chat are great instructional aids that give voice to students who do not even dare to raise their hands during a recitation session.

Another plus for social media as a learning tool is that most are free to use and many can be configured in such a way as to restrict the potential for inappropriate behavior. Kidblog.org, Edmodo, and Edublogs are just some of the school-ready social media platforms that have been purposely designed for academic deployment.

Artificial Neural Networks in Cardiac Care

A model that evolved out of Artificial Intelligence is Artificial Neural networks (ANN), often interchangeably referred to as Neural Networks. It is a mathematical or computational model that processes interconnected data (artificial neurons) to find a pattern in that data. In this process you have input data, that goes through a connectionist approach to output data. The system adapts and learns through the multitude of data that flows through it. The result is an expert decision making, or even predicting system, with a near 100% accuracy. Small wonder, clinicians have been using AI and expert systems to provide better and timely healthcare to their patients.

Artificial Intelligence in Medicine (AIM) has nicely summarized Some of the areas they have applied this to. They are:

Generating Alerts and Reminders
Diagnostic Assistance
Therapy Critiquing and planning
Agents for Information Retrieval
Image recognition and interpretation
In a study during the late 1990s, researchers Lars Edenbrandt, M.D, Ph.D., and Bo Heden, MD., Ph.D., of the University Hospital, Lund, Sweden, ventured to include 1,120 ECG records of Heart Attack patients, and 10,452 records of normal patients. The neural networks were found to be able to use this input data, and establish a relationship and pattern. This leaning phase was internalized by the system, and started identifying patients with abnormal ECGs with a 10% better accuracy than most clinicians/cardiologists on staff.

But a point to note here is that, technology such as the ANN cannot replace a Doctor who looks at several more factors and fine prints before diagnosing a Heart Attack. It can be used just as a means to complement and speed up the diagnostic process.

Speaking of other factors in determining Heart Attacks, an interesting research work had been published in a scientific journal from the Inderscience group, the International Journal of Knowledge Engineering and Soft Data Paradigms (IJKESDP) under the name "A computational algorithm for the risk assessment of developing acute coronary syndromes, using online analytical process methodology" (Volume 1, Issue 1, Pages 85-99, 2009). Four Greek researchers had ventured to develop a computational algorithm that evolved out of a more current technique, namely Online Analytical Processing (OLAP). They used this methodology to build the foundations of a "Heart Attack Calculator". The advantage of OLAP is that it provides a multidimensional view of data, that allows patterns to discerned in a very large dataset, that would have been otherwise remained invincible. It takes into account numerous factors and dimensions, while making an analysis. The research team obtained data from about 1000 patients that have been hospitalized due to symptoms of Acute Coronary Syndrome. This data included details on their family history, physical activities, body mass index, blood pressure, cholesterol, and diabetes level. This was then matched to another set of similar multi dimensional data from a group of healthy individuals. All this data were used as inputs to the OLAP process, to explore the role of these factors in assessing cardiovascular disease risk. At various levels of the factors, intelligence could be gathered to be used as a combination of dimensions, for future diagnosis of the extent of risk.

The ANN is more a "teachable software", that absorbs and learns from data input. When properly computed, even at a fast pace with a tried and tested algorithm, it develops patterns within the input data, or a combination of multiple data dimensions or factors, to which a given situation can be compared to, and a prognosis declared.

In 2009, some researchers in Mayo Clinic studied 189 patients with device related Endocarditis diagnosed between 1991 and 2003. Endocartitis is an infection involving the valves and at times the chambers of the heart, that are often caused due to implanted devices in the heart. The mortality of due to the infection could be as high as 60%. The diagnosis of such an infection required transesophageal echocardiography, which is an invasive procedure involving the use of an endoscope and insertion of a probe down the esophagus. Needless to say, this was a risky, uncomfortably and expensive procedure. The researchers at Mayo, fed the data from these 189 patients int the ANN, and had it undergo three separate "trainings" to learn to evaluate these symptoms. Upon being tested with different sample populations (only known cases, and then a overall sample of a combination of both known and unknown cases), the best trained ANN was able to identify Endocarditis cases very effectively, thus eliminating the need for such an invasive procedure.

With modern day e-health becoming more and more data centric, access to relevant patient data is gradually becoming extremely convenient. AI and Expert systems with its ANN and computational algorithms, has tremendous opportunities to speed up diagnosis, and effect patient care with speed and more and more accuracy. As AI advances, it will be interesting to see how it marks its footprints in Cardiovascular, Neuro, Pulmonary, and Oncology diagnosis and care.

The Inspiration of Being a Web Design and Development Freelancer

Investigate the Benefits of a website architecture and web improvement specialist

It is safe to say that you are prepared to encounter the soul of flexibility as a specialist? Or, then again do you get some anxiety with the sentiment a moving stone that accumulates no greenery? Simply ahead and investigate the advantages of being a specialist and wear the mantle of being your own lord. Get into the independently employed module and appreciate the position of a self employed entity. Despite the fact that being a specialist implies that one is not dedicated to a specific organization of business, consultant regularly need to sign contracts with NDAs, verbal concurrences with the consultant being qualified for charge by the hour, day, per extend premise, piece rate or an esteem based evaluating understanding that offers quality and incentive for the customer.

There are many fields through which the consultant can acquire, for example, copywriting, content written work, editing, visual communication or news coverage. The regions that a specialist can bring home the bacon likewise incorporates site advancement, distributing, filmmaking, screenwriting, counseling, deciphering, visit directing, website architecture, photojournalism, music, filmmaking, beautifying agents, scents or aromas, acting, occasion arranging, wedding organizer, PC programming, interpreting, video altering and video generation. With a large group of expert fields to browse, specialists can take up the ones that suits them the best or the ones they have a fitness for, or are prepared in. The advantages that consultants can get are numerous as an independent occupation gives them abundant time being locally established with work gone up against an impromptu premise.

With recognitions changing with the appearance of innovation, the changing situation of present day ways of life and the requests of different ventures who need to eliminate overheads, consultants can appreciate an extent of employments in different fields and add to their income. Other than being adaptable, an independent occupation gives the upside of picking businesses and associations to work with and settling on a choice about the timeframe included and the work environment. Being your own particular ace has been an extremely engaging suggestion and consultants can enjoy the advantage of making major decisions at whatever time, wherever, anyplace. With the idea of procuring from products floods of salary, specialists at times, don't confront challenges on the off chance that one of their bosses is experiencing money related troubles and is not ready to pay on time or can't pay the stipulated sum.

Supported by acquiring a wage which is locally established and additionally helpful, specialists can sharpen their aptitudes and add to their salary by going up against more than one employment by settling on getting or experiencing preparing in another more lucrative field. Being adaptable and multi-faceted additionally helps specialists and acquires salaries that proved to be useful when costs emerge. Organizations and associations can encounter money related opportunity of eliminating costs, for example, assess and different overheads and consent to give the specialist an expanded installment. Despite the fact that extremely perfect, getting on an autonomous stage can in any case have its own high points and low points that can be overcome by specialists. This would incorporate absence of inspiration, extended periods of work, time taken for endorsement of articles, reworking of material and other tedious undertakings.

Outsourcing does not contain just of a luxurious situation, but rather likewise different conditions that regularly prick the inflatable. Being a vocation that requires the consultant to invest energy alone frequently prompts absence of inspiration. Add parts of support to your calendar and reward yourself toward the finish of a taxing day by taking in some natural air on a relaxed walk or by doing exercise. Consultants need to set aside off opportunity to utilize their muscles, fingers and joints that would facilitate the anxiety and give their bodies adaptability and appreciate a merited break. There are different variables, for example, fund and paying bills that may make an inability to write and deny the customer of value work. A specialist needs to mange his/her funds adequately and attempt to create more wage by expanding their work. Obviously, this means meeting as well as messaging potential businesses. Get innovative and pick an independent range that would suit abilities, take in a moment dialect so you can likewise change into an interpreter or go up against a simple low-paying second employment to supplement your wage.

Consultant can transform bane into help by looking into the market with an expert state of mind and extend the income perspective. Being a consultant does not qualifies one for appreciating social insurance arrangement, annuity and assessment exceptions. Consequently it is of absolute significance that a specialist ought to encompass his/her money related matters with knowledge so that assessments are paid and all bills are met easily. Specialists have the advantage of systems administration like different experts and can build their hover of contacts at their own time and accommodation. Other than setting up a portfolio, consultants can add to their validity with business cards that can be flowed among partners, family, companions and associations. Taking a break from work can give the consultant time to go to occasions, displays and exchange fairs to make and secure contacts.

Specialists can appreciate the advantages of being all alone and exercise their ability that gets higher efficiency. Other than getting acknowledgment for an extraordinary thought from an association, specialists can procure more data from customers and enterprises that expands their perspectives and offers a focused edge. Giving customers unique work and thoughts support a consultant's picture where they head their own particular outfit and not be a worker of the organization. Specialists can increment and add to their portfolios with an incredible scope of customers and subjects/themes that they have encountered.

What Is the Relevance of Technology?

"Innovation over the long haul is superfluous". That is the thing that a client of mine revealed to me when I made an introduction to him about another item. I had been discussing the item's elements and benefits and recorded "best in class innovation" or something to that impact, as one of them. That is the point at which he put forth his expression. I understood later that he was right, at any rate inside the setting of how I utilized "Innovation" in my introduction. In any case, I started contemplating whether he could be ideal in different settings also.

What is Technology?

Merriam-Webster characterizes it as:

1

a: the down to earth utilization of learning particularly in a specific region: building 2 <medical technology>

b: a capacity given by the handy utilization of information <a auto's fuel-sparing technology>

2

: a way of finishing an undertaking particularly utilizing specialized procedures, techniques, or information

3

: the specific parts of a specific field of attempt <educational technology>

Wikipedia characterizes it as:

Innovation (from Greek τî­χνη, techne, "workmanship, expertise, sly of hand"; and - λογî¯α, - logia[1]) is the making, alteration, utilization, and learning of instruments, machines, strategies, specialties, frameworks, and techniques for association, so as to take care of an issue, enhance a prior answer for an issue, accomplish an objective, handle a connected information/yield connection or play out a particular capacity. It can likewise allude to the gathering of such apparatuses, including hardware, alterations, courses of action and methods. Advancements essentially influence human and other creature species' capacity to control and adjust to their common habitats. The term can either be connected by and large or to particular territories: cases incorporate development innovation, restorative innovation, and data innovation.

Both definitions rotate around a similar thing - application and utilization.

Innovation is an empowering agent

Many individuals erroneously trust it is innovation which drives development. However from the definitions over, that is obviously not the situation. It is opportunity which characterizes advancement and innovation which empowers development. Think about the great "Form a superior mousetrap" illustration educated in many business colleges. You may have the innovation to construct a superior mousetrap, however in the event that you have no mice or the old mousetrap functions admirably, there is no open door and afterward the innovation to fabricate a superior one ends up plainly superfluous. Then again, on the off chance that you are invade with mice then the open door exists to improve an item utilizing your innovation.

Another case, one with which I am personally natural, are customer gadgets new businesses. I've been related with both those that succeeded and those that fizzled. Each had one of a kind driving edge advances. The distinction was opportunity. Those that fizzled couldn't discover the chance to build up an important development utilizing their innovation. Indeed to survive, these organizations needed to transform intermittently into something entirely unexpected and on the off chance that they were fortunate they could exploit subordinates of their unique innovation. As a rule, the first innovation ended up in the piece store. Innovation, therefore, is an empowering agent whose extreme incentivized offer is to make upgrades to our lives. So as to be important, it should be utilized to make advancements that are driven by circumstance.

Innovation as an upper hand?

Many organizations list an innovation as one of their upper hands. Is this legitimate? At times yes, yet In many cases no.

Innovation creates along two ways - a transformative way and a progressive way.

A progressive innovation is one which empowers new enterprises or empowers answers for issues that were beforehand unrealistic. Semiconductor innovation is a decent case. Not exclusively did it generate new ventures and items, however it brought forth other progressive advances - transistor innovation, coordinated circuit innovation, microchip innovation. All which give huge numbers of the items and administrations we devour today. Be that as it may, is semiconductor innovation an upper hand? Taking a gander at the quantity of semiconductor organizations that exist today (with new ones framing each day), I'd say not. What about microchip innovation? Once more, no. Bunches of microchip organizations out there. What about quad center microchip innovation? Not the same number of organizations, but rather you have Intel, AMD, ARM, and a large group of organizations building custom quad center processors (Apple, Samsung, Qualcomm, and so forth). So once more, a sorry upper hand. Rivalry from contending advancements and simple access to IP mitigates the apparent upper hand of a specific innovation. Android versus iOS is a decent case of how this functions. Both working frameworks are subordinates of UNIX. Apple utilized their innovation to present iOS and picked up an early market advantage. Nonetheless, Google, using their variation of Unix (a contending innovation), made up for lost time moderately rapidly. The explanations behind this lie not in the basic innovation, but rather in how the items made conceivable by those advancements were conveyed to market (free versus walled plant, and so forth.) and the distinctions in the key dreams of each organization.

Transformative innovation is one which incrementally expands upon the base progressive innovation. Be that as it may, by it's extremely nature, the incremental change is simpler for a contender to match or jump. Take for instance remote cellphone innovation. Organization V acquainted 4G items earlier with Company An and keeping in mind that it might have had a transient favorable position, when Company A presented their 4G items, the preferred standpoint because of innovation vanished. The buyer backpedaled to picking Company An or Company V in view of value, administration, scope, whatever, however not in light of innovation. In this manner innovation may have been applicable for the time being, however in the long haul, wound up plainly superfluous.

In this day and age, advancements have a tendency to rapidly move toward becoming commoditized, and inside a specific innovation lies the seeds of its own passing.

Innovation's Relevance

This article was composed from the imminent of an end client. From an engineer/architect point of view things get murkier. The further one is expelled from the innovation, the less applicable it progresses toward becoming. To an engineer, the innovation can resemble an item. An empowering item, however an item in any case, and in this manner it is exceptionally significant. Bose utilizes a restrictive flag preparing innovation to empower items that meet an arrangement of market prerequisites and in this manner the innovation and what it empowers is significant to them. Their clients are more worried with how it sounds, what's the value, what's the quality, and so forth., and less with how it is accomplished, in this manner the innovation utilized is significantly less applicable to them.

As of late, I was included in a discourse on Google+ about the new Motorola X telephone. A ton of the general population on those posts pummeled the telephone for different reasons - cost, bolted boot loader, and so on. There were likewise a lot of thumps on the way that it didn't have a quad-center processor like the S4 or HTC One which were estimated correspondingly. What they neglected to handle is that whether the producer utilized 1, 2, 4, or 8 centers at last has no effect the length of the telephone can convey an aggressive (or even best of class) list of capabilities, usefulness, cost, and client encounter. The iPhone is a standout amongst the best telephones at any point created, but then it keeps running on a double center processor. Despite everything it conveys one of the best client encounters available. The components that are empowered by the innovation are what are significant to the purchaser, not simply the innovation.

The pertinence of innovation in this way, is as an empowering influence, not as an item highlight or an upper hand, or any bunch of different things - an empowering influence. Taking a gander at the Android working framework, it is an amazing bit of programming innovation, but Google gives it away. Why? Since independent, it does nothing for Google. Giving it away enables different organizations to utilize their skill to fabricate items and administrations which then go about as empowering influences for Google's items and administrations. To Google, that is the place the genuine esteem is.

The ownership of or access to an innovation is critical for what it empowers you to do - make advancements which take care of issues. That is the genuine pertinence of innovation.

THE MAGICAL ARTS

Spiritual Quantum Physics tells us that there exists an infinite ocean of thinking intelligent energy called the Quantum Ocean or Mind of God. Everything that ever was, is or will be exists there. There is neither time nor space there.

All the magical arts are there and you can tap into them with your own mind.

Six thousand years ago the Art of Magic was practiced by the priesthood who were among the highest and most brilliant men in the land.

This science spread to India and developed as Yoga. It spread into Tibet where it formed the basis of the Lamaistic systems of spiritual discipline. In China it developed into Taoism.

It then passed into the Western world. Hippocrates used the 'magnetic pass' or laying on of hands' in the cure of diseases.

Aesculapius relieved pain in inflamed parts of the body by breathing on them and stroking with his hands.

Medieval alchemists tried to create an analogical science by using physical elements as symbols of spiritual principles.

In the 17th century Paracelsus, Kirchner, Maxwell and others wrote books setting forth the theory that living bodies contained a magnetic fluid which was transmissible from one to another by the exercise of the will and imagination.

In the 18th century came Franz Mesmer, whose theory of hypnosis as a curative power swept through Europe like a conflagration.

In 1784 Benjamin Franklin and Lavoisier investigated Mesmer's theory and concluded that there was no evidence of an animal magnetic field. This report by two spiritually ignorant men finished Mesmer.

Had Mesmer been born a century later during the age of field physics and atomic energy research, when even a microbe is conceived as giving off energy waves, his fate would have been quite different.

Now in the Age of Aquarius with its new paradigm of the Laws of Spiritual Quantum Physics Mesmer's theory has been proven true.

Yesterday's magic is today's science. It is all there for you to read and use in the Quantum Ocean.
