Tracking Social Media Events and Logged-In Users in Google Analytics with Universal Analytics There was a great post on Technical Marketing about tracking social media events and logged-in users in Google Analytics using the new Universal Analytics. I would like to elaborate on the instructions to make it even easier to set up and get tracking. The following examples use a combination of JavaScript and jQuery. It is possible for these techniques to be used without jQuery, but some code re-factoring would need to be done.

Zuccotti—a designer and trends forecaster who founded the Overworld, a consultancy agency that specializes on the interaction between culture and technology—was curious to learn more about how our daily interactions come to define ourselves and what she might be able to learn about the things we “need, appreciate, consume, or simply touch.”

In January I had the pleasure of presenting to SuperWeek conference in Hungary. Pricing and Paying for Cures: Early Experience with HTA of Gene Therapy in the USA In a new OHE Seminar Briefing, Dr Steven Pearson, President of the Institute for Clinical and Economic Review (ICER), discusses early experiences of using HTA to assess Gene Therapy, setting out four challenges. First, uncertainty about clinical effectiveness makes it difficult for ICER to suggest an appropriate price. Pilot projects with some gene therapies involve five years of instalment payments.
