Did you know that your mitochondria, those often depicted as blue organelles with their own unique DNA, have a big role outside of being the power plants of your cells? Did you know that role involves killing off your own cells? Do you remember the anatomy of the cell that is responsible for your consciousness? Did you ever wonder just how ATP, adenosine triphosphate, serves as the unit of energy for your cells? All this and more in the Biology review edition of #VideosIWish on Vialogues! For those unfamiliar with it, Videos I Wish is a series of videos explaining or reviewing concepts which we wish were shown in a course. Feel free to ask me any questions you may have in the Vialogues.

 

How Dogs Reduce Stress in the Classroom

Having a dog in the classroom enhances the classroom experience. Children are found to be more careful throughout the classroom not to step on a dog, and they have been found to be more careful with interactions with each other. Blindfolded kids were asked to stroke a dog when they do, it has been found that the brain releases oxytocin, which is a stress-relieving hormone.

An experiment of 80 kids has been conducted in the vialogue below, with the ultimate goal of determining stress levels with exposure to dogs. There were three groups of kids that were asked to give a presentation. The first group would be able to give their presentation with the presence of the real dog that they knew well, the second group would be able to bring a friend, and the third group would be able to bring a stuffed animal. The findings show that the group of children that had been exposed to the dog had the least amount of stress prior to and after the presentation.

Having dogs in the classroom has benefits throughout the classroom, acting as a stress reliever as well as a moderator (e.g. when children are more careful when the dog is around). But this advantage comes at a disadvantage as well. A dog will easily provide distractions in the classroom, with children paying more attention in the dog rather than the teacher. There are both positives and negatives when dealing with dogs, but they will always remain an animal that we as humans can connect with.

How to Read

Submitted by Daniel Kim on Thu, 07/24/2014 - 7:47am.

Technology today pervades every inch of our society. You can see technology everywhere from our personal homes, to even in parks and fields. Nobody can really argue with the benefits that technology has bestowed upon us, since it helped revolutionize our world as we know it. It has helped us improve communication, transportation, and research.

However, with the advent of technology, comes a very big negative. Just like how a child seems to drift towards any new stimulus, we as a generation of people have gravitated towards the technology that is readily available to us. New inventions like the Nook, the smartphone, and the personal computers have rendered previously important inventions, such as the book, completely obsolete. Nowadays, people read through their personal rather than through their books, and there is a growing concern with the younger generations and their dependance on simple electronics.

The video below explains how to read a book in excruciating detail, almost to the point where we are dumbfounded in the way the speaker explains it. It is almost as if she is treating us like a baby. She simultaneously criticizes technology while she teaches us how to read, by saying things such as "you won't be able to swipe to turn a page, but don't worry your book isn't broken".

Never would one have imagined that rivals Apple and IBM would team up to collaborate on a project. But times must be changing as the two tech giants have teamed up to create new apps for business customers on the iPad and iPhone. The apps are scheduled for release sometime this year. The collaboration seems to have mutual benefits for the companies as IBM’s big data services and Apple’s mobile devices means there is a lot of room for creativity and cutting edge applications. Overall, there are 100 apps planned for the collaboration.

In most of our courses, understanding the basic concepts of the course is usually key success or failure. More often than not, we have had issues understanding the basic concept of a course. I had a hard time fully understanding the basic concept of critical thinking. After watching this video and its illustrations, I can confidently say I would have understood critical thinking if my professor had used this video during the days she thought that concept.

Sorry if this course sounds too technical for some of you and you have no interest in understanding it. However, This is one of the required courses that I have to take as an Electrical and Computer engineering student. I am watching this video in order to self teach myself and have some basic understanding before starting the class in the fall. Electrical work is hard to understand because it is done behind walls and is a mystery. This course might not fully convince you about how electricity or circuit works but it will help you understand some of the concepts used to produce electricity; something most of us take for granted.

As a follow up to my series of blogs about Financial Literacy, or lack thereof among American students, I came across this video that shares some helpful tips to college students regarding choices they make with their money. The video talks about loans, savings, and jobs; but more importantly credit cards, and the way they actually work. I wish I learned about some of the advice before I started college. Please, feel free to watch this video and add in your feedback.

 

Waiting to Prosper

There are a lot of young people across the world that attend school and also work. This is very common in the US and other Western countries. There might be many reasons why the Unites States and other countries are concerned about youth employment. I believe the primary reason for supporting youth employment is to develop future workers with the right skills. To this end, firms and companies accept students as interns. This in turn provides students with the experience they need for future careers. However, this is not the case in Egypt. Egyptian students are not worried about future opportunities since there is a lack of opportunities of any kind.

Two recent graduates, Youssef and Samer, highlight the situation in Egypt. They’ve both struggled to obtain jobs since graduating. Unlike many youth in this country, Youssef and Samer were not employed during their schooling years. When I came across this article, I realized that compared to my peers across the globe, I’ve been fortunate and as long as I stay on the right path, which I believe that I am, my goals would be achieved.
