Cool infographic: Everett Roger’s Diffusion of Innovations

One of the advice I got before entering my Ph.D. program was to make sure I focus on theory. Those of us in communication love theory. While I’m still trying to figure out which theories will form part of my long-term research agenda, I’m very much drawn to Everett Roger’s work on diffusion of innovations/information. This is a very important theory in communication in general but particularly so in understanding health communication exposure and effects. So, I was quite excited to see the folks over at thornely & hill create an inforgraphic about diffusions of innovations.

So, what is diffusion of innovations about? See more after the jump.



Don’t forget to relax


A few months ago, I found this poster on the website that reminded me to relax. This is one of the notes I keep within sight at all times. This is important because I have a habit of being high strong, and my blood pressure has a habit of being high.

I found out I had elevated blood pressure while still a teenage. Right after migrating to the United States, one of my first medical acts was to go to a clinic at the same time every day for five straight days to check my blood pressure. The doctors were convinced I had high blood pressure. For the record, I don’t. From that time onwards, I would usually spit out my blood pressure reading even before the machine kicked out it’s numbers.  However, during the past few years, my blood pressure has been slowly going down due to lifestyle changes and I guess my attempts at relaxation. I’m still amazed when I see a low numbers.

As I start my doctorate and during this entire stage in life. I’ll have to remember to relax. It’ll be ok. And, my blood pressure will continue to thank me.

Like the message “keep calm and keep walking”, this is one of the simple mantras that can aid in better health. Sometimes, it’s the simplest communication messages that have the biggest impact (on our health).

Keep Calm. Keep Walking. Carry On.



I saw this today in my Facebook feed (Courtesy of Canada Walks via PAHO) and knew I needed to share it. It’s based on the hugely popular “Keep Calm and Carry On”. The message is very simple and clear. The behavior is simple. Yet, getting people to talk more is not always simple.

I remember growing up in Dominica, walking was the norm. I walked every day from home to school, home to church, home to the market. We lived close enough to town that walking was easy.  Now, when I go back, everyone wants to take the bus or use the car. Who’s still walking?

So, go on a share this mantra. Keep Calm. Keep Walking. Carry On.
