As the past years have proven, the methods for conducting and distributing research that we’ve inherited from our disciplinary traditions can be remarkably brittle in the face of rapidly changing social and mobility norms. The ways we work and the ways we meet are questions newly opened for practical and theoretical inquiry; we both need to s…[Read more]

Patient-centered care evolves around proper coordination between healthcare providers in consultation with patient needs. Oftentimes, children play a passive role in their health care because of the controversy around age and lack of consensual abilities. The impact of engaging children early on to empower decision-making skills has been proven to…[Read more]

It is known that each natural number greater than 1 can be expressed as a unique product of prime numbers, namely the prime factorization. For example, 84=2×2×3×7. By summing up all prime factors of 84, we obtain 2+2+3+7=14. Since 14=2×7, we further sum up all prime factors of 14 to obtain 2+7=9. Since 9=3×3 and 3+3=6, we can continue the same…[Read more]
