Tranquil Pavement

Tranquil Pavement is an online map recently launched by the Tranquil City project based in London, in association with the Outlandish Cooperative and funded by Organicity. It aims to highlight tranquil places to visit, if the hustle and bustle of city life gets too much, by plotting “crowdsourced “locations – referenced in an Instagram feed […]

Citizen Science & Scientific Crowdsourcing – week 5 – Data quality

This week, in the “Introduction to Citizen Science & Scientific Crowdsourcing“, our focus was on data management, to complete the first part of the course (the second part starts in a week’s time since we have a mid-term “Reading Week” at UCL). The part that I’ve enjoyed most in developing was the segment that addresses … Continue reading Citizen Science & Scientific Crowdsourcing – week 5 – Data quality

Chiswick Timeline

The Chiswick Timeline, a mural of maps showing the history of the pleasant west London neighbourhood, was successfully crowdfunded and launched last month. It appears alongside a road as it passes underneath a railway bridge by Turnham Green station. A commemorative book, reproducing the work, is available to buy online or at Foster’s Bookshop on […]

Dockless Continues to Expand – Here’s the Data

It looks like Brent will be the next London borough to get dockless bikeshare, with Mobike likely to be setting up in the borough within the next few weeks. The operator is not confirmed, although strongly hinted at, including by the council themselves. The choice of Mobike makes sense, as the operator already has a … Continue reading Dockless Continues to Expand – Here’s the Data

Citizen Science for Observing and Understanding the Earth

Since the end of 2015, I’ve been using the following mapping of citizen science activities in a range of talks: The purpose of this way of presentation is to provide a way to guide my audience through the landscape of citizen science (see examples on SlideShare). The reason that I came up with it, is … Continue reading Citizen Science for Observing and Understanding the Earth

Citizen Science & Scientific Crowdsourcing – week 3 – Participation inequality

One of the aspects that fascinates me about the nature of participation in citizen science and crowdsourcing is the nature of participation and in particular participation inequality. As I’ve noted last week, when you look at large scale systems, you expected to see it in them (so Google Local Guides is exhibiting 95:5:0.005 ratio). I knew … Continue reading Citizen Science & Scientific Crowdsourcing – week 3 – Participation inequality

Railway Station Numbers

The ORR publishes station entry/exit numbers on an annual basis, on a “best guess” basis, using ticket sales, gate information and modelling. The data is split by ticket type – full fare, reduced fare (off-peak tickets, tickets bought with railcards, advance tickets, child tickets etc) and season tickets. They make this data available as an … Continue reading Railway Station Numbers

Winter Lights

If Lumiere London, which finished yesterday, has whet your appetite for seeing artistic displays of light after dark, then there is another festival of lights which runs until Saturday. It’s at Canary Wharf and called Winter Lights. Think Lumiere London, in a smaller area and without the huge crowds. And, like the King’s Cross, it’s […]

Lumiere at King’s Cross

King’s Cross is one of the six Lumiere London areas, where light-based artworks are on display every evening until Sunday. We looked at the general maps of the event yesterday, but we discovered also that King’s Cross has its own map, showing where the exhibits are. You don’t have to follow the marked route, although […]

Launching a citizen science course – week 1

Today, I gave the opening lectures of the new UCL course ‘Introduction to Citizen Science and Scientific Crowdsourcing‘. In a way, it was more work than I originally thought, but I also thought that I’m underestimating the effort – so it’s not completely unexpected. Although I am responsible for the first installation of Moodle, the … Continue reading Launching a citizen science course – week 1

New Paper: Cancer and Social Media

Continuing our work on geosocial analysis we recently had a paper entitled “Cancer and Social Media: A Comparison of Traffic about Breast Cancer, Prostate Cancer, and Other Reproductive Cancers on Twitter and Instagram” published in the Journal of Health Communication. In the paper we  present a comparative study of differences in messaging for women’s and men’s cancer campaigns on social media through three discrete approaches. 
  1. we directly compare the incident rates of women’s and men’s cancers in the United States to the corresponding levels of traffic that these cancers elicited during World Cancer Day across two social media platforms, Twitter and Instagram. 
  2. we examine social media activity for breast cancer versus prostate cancer on both Twitter and Instagram during the dedicated month-long campaigns (October and November, respectively). 
  3. we compare the top terms associated with each campaign on these two social media platforms to discover whether there are differences in the terms associated with these online discussions.
Below you can read the abstract to our paper, see some of our results and at the bottom of the post have the full citation and link to the paper.

Abstract: 

Social media are often heralded as offering cancer campaigns new opportunities to reach the public. However, these campaigns may not be equally successful, depending on the nature of the campaign itself, the type of cancer being addressed, and the social media platform being examined. This study is the first to compare social media activity on Twitter and Instagram across three time periods: #WorldCancerDay in February, the annual month-long campaigns of National Breast Cancer Awareness Month (NBCAM) in October and Movember in November, and during the full year outside of these campaigns. Our results suggest that women’s reproductive cancers – especially breast cancer – tend to outperform men’s reproductive cancer – especially prostate cancer – across campaigns and social media platforms. Twitter overall generates substantially more activity than Instagram for both cancer campaigns, suggesting Instagram may be an untapped resource. However, the messaging for both campaigns tends to focus on awareness and support rather than on concrete actions and behaviors. We suggest health communication efforts need to focus on effective messaging and building engaged communities for cancer communication across social media platforms.
