DEVY – The new workplace assistant

Incorporating technology into our lives has become commonplace now. Most people are familiar with Siri or Alexa, two iconic conversational tools that can do small things like play a song to something more physical like turning off the lights. But what if there was similar technology that could help you with your everyday job?

Conversational Development Assistant

Computer science student Nick Bradley came up with an idea of a conversational development assistant (CDA) while in the midst of his everyday code work. His master’s thesis was on the feasibility and also practicality of such a device. He noticed that the majority of his time and effort was spent on small details, very tedious and what he describes as “grunt work”. It took away from the higher end and more difficult portions of his coding work. Bradley decided to experiment with a technology-based assistant that would essentially do the “grunt work” so he could focus on other aspects and not worry about it. And so DEVY was born, diagram shown below:

Don’t be confused by the picture, it actually is Amazon’s Alexa. However Bradley was able to program DEVY into the device, using Alexa as a medium and therefore obviating the need to create a new conversational platform from scratch.

Uses of DEVY

Bradley primarily created DEVY for software engineers and coders. Bradley however sees DEVY going way beyond the field of software and coding. There are applications of DEVY in the legal field, perhaps with helping lawyers search case files or in the medical field, notifying physicians of any conflicting medication orders. An example of what can be done with DEVY and its future potential is shown in the video below:

The application to medicine is particularly interesting as drug informatics is actually one of the leading causes of medical issues in healthcare settings. Technology company Nuance describes the applicability of conversational software assistants in hospitals on their website here.

Invasion of technology?

A major concern about technological developments like DEVY is that we are incorporating too much technology into our lives. People have expressed concerns of conversation AI (artificial intelligence) like Siri or Google constantly listening in and secretly sending consumer information to their home company. These sorts of conversational assistants could indirectly be breaching our privacy and confidentiality. Our group discusses this in more detail and describe why this issue is not a concern with DEVY in our following podcast:

Future for Devy

The plans for DEVY as described is for it to branch out into job industries and help people of all professions with the daily work. The thing to keep in mind is that DEVY is no substitute for an actual person, it is not meant to replace actual people. DEVY is meant to be an assistant on the side that essentially allows you to be more productive and time-efficient with your work.

The Secret to Speed- Symmetry

What makes fast runners so fast? Sure, strong muscles, hard work, and good technique all contribute to speed- but so does symmetrical knees?

The Proof

Scientists have recently discovered the surprising and remarkable effect symmetric knees have on running efficiency. Robert Trivers, an evolutionary biologist, took a team to Jamaica to investigate if there is any correlation between elite runners and their body symmetry. In one study, the researchers asked the club track and field members to give their best times in their specific running events, such as the 100m dash, 200m, 400m, or 800m. They found that in every single event group the fastest times belonged to the athletes with the most symmetric knees, not with the most muscle mass, lung capacity, or best technique.

To further confirm these results, they performed another study in which the research team measured the knee symmetry of 73 elite sprinters, including Olympic gold medalist Shelly-Ann Fraser-Pryce. They compared their measurements with those of 116 local non-runners who were of the same age and sizes as the elite athletes. They found that the sprinters had much more symmetrical knees than the non-runners, concluding that it is indeed a significant contributing factor to running efficiency. “Among the very best sprinters in the world, knee symmetry predicts who’s going to be the best of the best,” Trivers confirms after analyzing these results.

But Why Knee Symmetry?

One reason why knee symmetry could be such a dominant factor in predicting speed is because running is naturally a symmetrical movement, and therefore it will favour symmetrical traits. By not having to compensate for non-symmetric mechanisms, sprinters with knee symmetry are able to save energy and be more efficient in every stride. In addition, numerous studies have confirmed that body symmetry is positively associated with genetic quality and developing advantageous traits, which may also contribute to the correlation between knee symmetry and speed.

What’s Next? 

This study has significant value as the results provide the basis for further research opportunities in the evolutionary biology and sports science fields. Evolutionary biologists may be interested in the genes that develop these symmetrical traits, questioning if they provide any other advantages to humans other than speed.  The track and field community and sports scientists may be curious to explore if there is any way to specifically increase knee symmetry through training in the hopes of it increasing speed significantly.

Furthermore, this finding has prompted more research into this topic and has led Trivers to address further questions, like are runners so symmetric because of good genes or because of the amount of exercise they do? Is it a cause or an effect? Nonetheless, there is a clear correlation between a high degree symmetry and being of the fastest humans. So, if you have symmetrical knees, you might very well be the next Usain Bolt.
