In preparation for our new Office Warming Party today, our creative team decorated our office with a special chalkboard mural. Check out our new time-lapse video documenting the creation of our chalk mural here:

Have you ever wanted to learn how to create your own time-lapse video? To learn more about how we created ours, read on to follow the five steps the TechChange creative team took to produce this video:

Step 1: Establish how long you want your final video to be.

We wanted to keep the video short and sweet at 1 minute.

Step 2: Figure out how long your time-lapse will last

Most videos run at between 24-30 frames per second. This means that for 60 seconds of final video, we would need a minimum of 1,440 still shots from the camera in order to fill each frame with a photo (24 frames/second x 60 seconds = 1,440 frames).

Step 3: Estimate how long it will take to film all the action you’re trying to capture.

We needed to make sure that Rachel, Pablo, and Alon would be able to finish in the amount of time that it would take our camera to shoot those 1,440 exposures. If we were to shoot at one-second intervals, our camera would only be running for 24 minutes. Now, our creative team is fast, but not that fast.

By estimating that it would take the team two hours (120 minutes) to complete the chalk mural, we can solve for 1,440* interval = 120 minutes to get that interval = 0.083 minutes, or about 5 seconds between shots.

Step 4: Set up your camera and film

To create the time lapse, we mounted our Panasonic GH3 onto a tripod and set it to take one photo every five seconds for 1,440 shots.

Step 5: Import your still image series into video and edit

After setting the camera to take these exposures, we imported the 1,440 stills into PremierePro by using the option to import an image sequence, rather than as individual stills. This import method is quick and matches one photo to each frame of the video sequence. Lastly, we cropped the video so that it would fill a 16:9 aspect ratio, added music, and edited in the TechChange logo animation.

Come check out the chalk mural in person tonight, May 7, 2014, at the TechChange Office Warming Party! RSVP here. We can’t wait to see you!

By Sairah Yusuf, TC141: Mapping for International Development (Fall 2013) alumna

Before taking this Mapping for International Development course last fall, I had absolutely no previous background on mapping tools, so everything about digital mapping was new to me. For my course final mapping project, I created a digital map of the countries and locations of participants of an international training camp held by Generations For Peace (GFP) in November 2013 (Amman Camp 2013). Given my involvement in evaluating the impact of this training, I wanted a way to visualise the effectiveness of the training.

Here are the steps that I took for my introductory experience in creating a map for my work at Generations For Peace:

Step 1: Define the purpose of your map

Throughout the course, the importance of defining the purpose of your digital map as a first step emerged with debates regarding representation and privacy concerns. My aim with this map is to understand the cascading effect over time of these Generations For Peace volunteers, who will be passing on their skills to new volunteers in their home countries in the Middle East. By maintaining this map from November 2013 to November 2015, I hope that it will be possible to visually demonstrate the geographical impact of this training.

Step 2: Select your dataset

I used data from Amman Camp 2013, including the home country of each individual trained and the geographical reach of the training. I felt that this data was simple enough to work with, given that this was my first exposure to mapping. That said, I had to create the dataset from scratch, entering street addresses/locations for each participant.

Geocoding data in the MENA region proved to be the biggest challenge because geocodes for most street addresses (which were predominantly in Arabic) could not be found in the APIs I used. In addition, we had trainees from the occupied Palestinian territories at the GFP Camp. I struggled with pinpointing their locations on the map since the occupied Palestinian territories did not show up as a country option in many of the geocoding tools I tried. I had to get around this by tagging individuals from this region as hailing from Israel and then manually changing the name later to reflect their location. This issue was important to deal with because I did not want any of these trainees to view the map I had created and feel like I had misrepresented where they were from in any way due to geo-political sensitivities.

Step 3: Select your mapping tool or software

The Mapping course featured a variety of tools including Google Maps Engine, MapBox, Ushahidi, OpenStreetMap, CaerusGeo, and Palantir. I chose the Mapbox/TileMill combination over other options because I felt it allowed me to customise my map more – I could colour in different countries and introduce different levels of interactivity within the map.

Step 4: Choose your design

My design choices were partly shaped by wanting to keep my map easily readable, using block colours and simple labels, and also to keep my map customisation as simple as possible since this was my first mapping exercise. I also wanted the countries in question to stand out quite clearly.

By introducing dots in different colours for new individuals these volunteers train in their own countries, over the course of 2 years, for example, this would show how much of a geographical “spread” the training from Nov ’13 had. It would also help distinguish between volunteers with different levels of training. For example, as time goes on and individuals complete GFP programmes and further training, it is possible to change the colour of the dots representing those who were trained at the original Camp to red, demonstrating their status as a GFP “Pioneer.” Any new volunteers they train can be represented in “blue.” The idea is therefore to improve this map and maintain it over a period of time to represent these changes.

Filling out more details in the second click feature can provide relevant information about each individual – what they’ve done in the past and what programmes they are working on now, for Generations For Peace.

Takeaways:

Basic mapping software can actually be quite accessible, even with very little technical training. However, there’s definitely something of a “glass ceiling” in its use, after which more technical expertise is required. Overall, Mapping for International Development was a really great course, and I’ve already recommended it to others! This online course covers debates in the field in some depth, but also focuses on mapping tools in the field in enough detail to have a platform to build on afterwards.

Bob Corbett’s final mapping project on flood-prone areas in Bangladesh. (Note: this map was prepared as a mapping exercise. Anyone viewing the map should understand that it would need to be reviewed and validated by a qualified expert before it should be relied upon.)

By Bob Corbett, TC141: Mapping for International Development alumnus

During my undergraduate work in Landscape Architecture, I learned a method of analyzing spatial data by overlaying various types of information on acetate sheets or tracing paper developed by Ian McHarg, a Scottish landscape architect. The technique is described here (Note: I am not related to the author). I have always been fascinated by this technique and the GIS capabilities available today make this type of analysis readily possible. This offline overlay technique was the basis of my final mapping project in TC141.

In mid-2011, I launched SMS in Action, an Ushahidi Crowdmap that lists text message based programs worldwide that contribute to the social good. To date, nearly 240 programs classified under 29 different categories have been profiled on SMS in Action and viewed by thousands of visitors from 119 countries. With my general interest in mapping piqued by my Crowdmap experience, I ventured into crisis mapping with the Standby Task Force and more recently, Crisismapper deployments using the Tomnod platform. I have since worked on a variety of crisis mapping efforts from locating refugee encampments in Somalia, to tracking forest and bush fires in Colorado and Australia and identifying storm damage after Typhoon Haiyan/Yolanda in the Philippines to name a few.

TC141: Mapping for International Development

Taking the online course, Mapping for International Development, allowed me to combine my interests in ICT4D, international development, data visualization, and a love of maps. I very much enjoyed the format of TC141 with the combination of live presentations, weekly readings and videos, exercises, discussion forums, and the step-by-step instructions and “how-to” materials. Although I tried to “attend” each live presentation the fact that everything was archived for viewing at my convenience was a real plus. This being my first online course, I was surprised at the level of personal interaction available between participants as well as with the facilitator. Chris Neu was a great facilitator: always enthusiastic, arranged interesting presenters and shared an immense amount of information with course participants. I had no specific goals for the course at the outset other than to broaden my knowledge of available mapping technologies. I quickly realized TC141 provided me a chance to gain a capability to work with GIS, a long-term interest of mine. As a result, I selected QGIS, the open source GIS platform as the primary platform upon which to develop my course project.

Mapping with QGIS and MapBox’s TileMill
In a preliminary course exercise we were introduced to MapBox/TileMill. In a follow-up exercise I used MapBox/TileMill to create a simple map of the top ten world coastal cities at risk from flooding due to climate change – including Dhaka, Bangladesh. Given that we have a family friend from Bangladesh, I felt a more detailed investigation of flooding patterns in Bangladesh, an increasingly frequent problem, might lend itself to my major project for the course.

Drawing upon existing sources of information available via the Internet, I located shapefiles for administrative districts, the extent previous flooding, road systems, airport and hospital locations, topographic information, population data and more. After importing this information into QGIS I was able to identify recently flooded and flood prone areas of the country. Seeing how flooding can compartmentalize the country and disrupt the movement of people and relief supplies between areas, I then performed a quick search of key medical facilities and major airports to better understand which would be affected and which might be available to support relief efforts. The QGIS-based flood map was then exported into MapBox/TileMill where it was further refined using the tools and capabilities within the MapBox platform.

Mapping Bangladesh’s Flood-Prone Zones
Given that our Bangladeshi friend is engaged in development activities in the Khulna administrative district, I wanted to see whether flooding in Khulna might impact their area. Based on Internet research, I chose flooding from a 6-meter storm surge as the basis to work from. I then located ground elevation data for Bangladesh and loaded the file into QGIS. By filtering the elevation data I was able to “see” the general extent of flooding that might be expected in Khulna District by a 6-meter storm surge. I was very pleased with the resulting maps and the new skills and capabilities that I had gained. Prior to taking TC141, I was not even aware of QGIS or MapBox/TileMill. I feel compelled to note that my “flood maps” were solely academic mapping exercises and should not be interpreted to be definitive maps of anticipated flooding in Bangladesh. However, it did show me the new capabilities I had developed as a result of TC141.

Mapping in My Future
TC141 offered much more information than I have touched upon here. One area of discussion in the course was OpenStreetMap and Humanitarian OpenStreetMap. With my past involvement with crisis mapping I have developed an interest in pre-disaster planning. Although post-disaster efforts often involve hasty mapping after an event I am interested in what types of information and infrastructure could and should be mapped in advance of disasters as part of a preparedness program. For example, if we believe that climate change is expected to result in an increased frequency and intensity of tropical storms, typhoons, hurricanes, cyclones, etc. shouldn’t first responders and aid agencies have reliable maps to work with prior to a disaster? The Philippines experience, on average, 20 tropical storms per year. Accurate up-to-date maps of facilities and infrastructure needed to recover from such emergencies post-disaster should be mapped in advance in OpenStreetMap as part of a preparedness program. I am interested in learning more about the types of facilities and infrastructure that need to be mapped in advance as part of a preparedness effort and see OpenStreetMap as a logical platform for presenting that information.

Last Friday, the Johns Hopkins University’s School of Advanced International Studies (SAIS) launched its second annual Global Women in Leadership Conference with this year’s theme on “Technology in Action: Changing the Way Women Live and Work”. Throughout the day, female leaders spanning various aspects of the tech industry from across the world joined over 300 conference attendees to discuss the growing role of women in technology.

Supporting women in tech has always been important to TechChange and we’ve been excited to work with several organizations in this space. For example, we’ve worked with TechGirls at the State Department, Mobile Alliance for Maternal Action (MAMA), and partnered with USAID to create a course on Gender in Political Transition Environments. At the conference, it was great to hear from TechChange partners including MAMA’s Executive Director, Kirsten Gagniare, and Christopher Burns, Senior Advisor and Team Lead for Mobile Access at USAID, as they discussed mHealth and mobiles for international development. I found it personally inspiring to meet and hear from all of these female trailblazers in tech from across the world including Roya Mahboob, one of the first female IT CEOs in Afghanistan, and many more women leaders in technology driven industries.

In case you missed the event, here are a few highlights from this conference on women and technology:

Mobile is the future to empowering women worldwide. ICT4D and women’s global access to technology, especially mobile phones, was a strong theme throughout the event. According to keynote speaker, Kathy Calvin, President and CEO of the UN Foundation, there are currently more mobile phones than people in Africa. Also, the gender gap in mobile phone usage is wide: women have 300 million less mobile subscriptions than men.

Mayra Buvinic, Senior Fellow at the UN Foundation discussed how mobile phones empower women with mobility and privacy for financial transactions. A specific example of this empowerment is via M-PESA, which has been championed by women and has become a global model for mobile money, according to Jalak Jobanputra, venture capitalist and Managing Partner of FuturePerfect Ventures. With the excitement of emerging mobile technology, ThoughtWorks CTO, Rebecca Parson, highlighted an important point on how cultural and local context matters in ICT4D. She shared a poignant anecdote on a water project in Africa that was sabotaged by the women of a particular village. The motivation behind this damage was to preserve the already limited external interaction among the females of this community; the water pump technology took away the opportunity for women to interact with each other when they would collectively fetch water for their families.

2. Education is key for women to succeed in tech. In the conference’s final panel on “Leveling the Field: Expanding Economic Opportunities”, panelists shared several resources for women to build up their technical acumen and to get involved in tech communities. Be sure to check out groups and organizations like Tech LadyMafia, Rails Girls, CodeChix, Girls Who Code, and taking online courses with TechChange! Proficiency in tech tools opens up options for women in terms of job opportunities and work arrangements such as telecommuting and flexible work schedules when using collaborative software.

3. Women as consumers and producers of tech will result in products more catered to women. Jennifer Sherman, Senior Vice President of Product Mangement at Aptean, made a strong business case for design teams to consider women when creating new tech products. As tech companies are looking to grow their customer base, they will need to understand what women want as more women want to buy tech products that are specifically designed and built to meet their needs.

What was your favorite takeaway from the conference? How will the world be shaped by women consuming and producing more technology? Let us know your thoughts!

In the Fall 2013 session of TechChange’s online course on mHealth – Mobiles for Public Health, several participants attended the fifth annual mHealth Summit, a dynamic conference welcoming clinical, policy, tech, business, and academic experts to reflect on the evolution and future of mHealth.

Setting up an exhibition booth, the TechChange team attended the 2013 mHealth Summit to document the perspectives of mHealth newcomers and experts alike. We were fortunate to see some of the guest experts in our upcoming mHealth class such as Kelly Keisling from NetHope and the mHealth Working Group, Alain Labrique from Johns Hopkins, and alumnus Apera Iorwakwagh of the mHealth Alliance.

Among those we interviewed at the 2013 mHealth Summit, Dr. Layla McCay, physician, policy influencer, Huffington Post blogger, and TC309 alumna, shared her online learning experience in TC309:

See a segment of her blog post, Why mHealth Is Caught Between Vision and Reality, submitted as a TC309 final project, and published on HuffPost Tech:

At the mHealth Summit, Steve Case defined the three stages of entrepreneurship as hype, hope, and happiness. The collective imaginations of Summit delegates have been inspired by “hype” — we believe in the potential of mHealth as a health service improvement tool. That’s why we showed up. This conference seems to be planting us firmly in the “hope” phase — we recognize the significant barriers, the practical challenges to implementation. These are still early days in mHealth. What’s clear is that while mHealth may be caught between vision and reality, it’s not stuck there. It’s going to be amazing. Eventually. When it is, we’ll move into the “happiness” phase, where the potential is realized: the infrastructure’s in place, and mHealth is just a conventional, effective tool that everyone’s using in health care. The specifics of what this success will look like is impossible to predict as the field is moving so fast. What can be easier predicted, is at this point, the entrepreneurs will circle to the next hype.

We look forward to hearing and reading more from Layla and other TC309 alumni!

All of the top seeds survived the first round unscathed. In beating their competition, CAPS LOCK CRAZY, Russian Radio Appeal, The New Cartographers, and The Thorough Beards continued the streak of top seeds never losing to the bottom seed. But not all of the 2-seeds were as lucky. Here’s the bracket as of now:

We have more exciting matchups this week with heavyweights CAPS LOCK CRAZY and Hierarchy of Fonts slugging it out. But, first, here are 5 things we learned from the Round of 32:

There is no statistical correlation between Zombies and winning.
Two band names heavily featured zombies, but only one made it through to the Sweet Sixteen. Though zombies may be all of the rage these days, zombies alone do not seem to be enough to win.
Dollar Signs in Band Names Are So 2008.
Just like the dollar sign in Ke$ha, Ca$h Money Mug$ is out. Perhaps Ca$h Money Mug$ should never have made the band name wall in the first place, but it seems more likely that putting special characters in your band name just isn’t that cool.
Puns are the best.
So far, the most dominant band names have involved wordplay. Schroedinger’s Server, Beauty School Valedictorian, The Thorough Beards, and The New Cartographers. All winners, and all punny.
Ready, Aim, Advocate: Overrated or overmatched?
Despite being one of the strongest two seeds, Ready, Aim, Advocate only barely made the Sweet Sixteen. Maybe the band name isn’t as strong as initially believed or perhaps It’s A Different Noodle was drastically underseeded. Either way, the Selection Committee needs to reevaluate their reliance on the RBI (Really Bad Index) as a valuable indicator of potential tournament performance.
Nobody correctly predicted every matchup.
That’s right. After only 16 matchups, not a single perfect bracket exists! Unfortunately, nobody is going to win 1 Billion TechPoints this year from the coffers of TechChange CEO & President Nick Martin, but there are still more amazing matchups coming up!

Ready for the Sweet 16? Vote below.

We’re continuing to the next round of our Battle of the Band Names from last week’s Round of 32! We’re parodying the currently-on-going NCAA’s Basketball Tournament to choose the best of the band names we’ve come up with over the last year (all written on a whiteboard in our old office). We’re asking you for help in choosing the best band name!

By Lauren Bailey, TC309: mHealth – Mobile Phones for Public Health alumna

My final project for TechChange’s mHealth online course overlapped a final project for a master level global environmental health course. I’m currently working towards a Master of Public Health degree, concentrating in global environmental health, and specifically focusing in water, sanitation, and hygiene (WASH). I recently became interested in mHealth and decided to do my global environmental health course project on mHealth in the WASH sector. Since I was new to mHealth, I kept the project simple, touching on some basics. This background document includes: (1) applications of mHealth in WASH; (2) case studies; and (3) recommendations.

Throughout TC309, I became increasingly interested in how mHealth can be applied to behavior change, a major component of reducing WASH-related illness. The mHealth online course has been a wonderful way to learn about the different applications of mHealth, the challenges and successes of programs, and the future possibilities of mHealth. I’ve been inspired by many of the articles, discussions, and live presentations and am now incorporating mHealth into my master’s thesis.

Here is the infographic I created, using Piktochart as part of my course project:

Highlights:

Mobile phones offer a means to reach most at-risk populations, particularly those in rural areas, to change health outcomes.
More individuals in most African countries will have access to a mobile phone than they will to an improved water source by 2013.
Mobile phones have been deployed over the past decade as tools to improve water, sanitation, and hygiene.
Client education and behavior change communication, data collection and reporting, financial transactions and incentives, and supply chain management are potential mHealth applications categories.

How would you define mHealth?

Check out these mHealth definitions from a few of the attendees from last December’s mHealth Summit 2013 in Washington, DC, including several speakers and alumni from our mHealth online course:

Do you define mHealth differently or similarly? How has mHealth impacted your life and work?

Let us know, and join us for our next round of TC309: mHealth – Mobile Phones for Public Health!

It’s official! On March 31, TechChange will officially move to our new home on 13 & U St. NW.

While we’re looking forward to having more space, better light, and a more convenient location for our partners (as well as joining a U St. tech corridor), we’re going to miss our longtime home that has given us so much.

So, with the end of one chapter being a perfect time to reflect on the time we…..

10) Tried out our new Microwave S’Mores Maker (and made a mess).

9) Performed our Fail Song for the first time in front of a live audience.

8) Forgot to coordinate our outfits for the week. Whoops.

7) Met a new friend during an online event on mHealth.

6) Hosted Sondos and Nagham of the TechGirls Program for #JobShadowDay

5) Helped an excitable bird safely depart the premises.

4) Tried “prawn” potato chips from China after an extended staff trip.

3) Assembled our new “ANIMATION DOMINATION” creative machines.

2) Celebrated the Lunar New Year in style with Bánh tét

1) Tim Tam Slams. What else?

At TechChange, we can never get enough of mobile technology because it is constantly changing and reaching more people, even the most remote and low-income parts of the world. Many in the TechChange alumni community feel similarly as our Mobiles for International Development class remains to be our most popular online course to date with more than 400 participants from over 65 countries.

As Nick mentioned in the New York Times last year, mHealth, or mobiles for public health, is the most “evolved” of the mobile sectors. There are several large-scale mHealth campaigns that have focused primarily on maternal health and vaccination campaigns. As noted in the article, several companies such as Dimagi, ZMQ and Medic Mobile have made cellphones into tools for promoting health among rural health workers via open-source software.

These technology providers are not the only players in the mHealth industry. There are also mHealth program implementers, research institutions, initiatives, and policymakers/donors. Everytime we offer this mHealth course, we change our topics, tools and speakers due to the evolving nature of the field.

Here’s the speaker line-up for Spring 2014 who will be joining us for this upcoming round of the course, which runs March 31 – April 25, 2014:

Week 1
Dr. Elena Dmitrieva will discuss the maternal health Text4Baby program in Russia.
Dr. Alain Lebrique representing the Johns Hopkins University Global mHealth Initiative, will explain the role of mHealth in achieving a continuum of care.

Week 2
Jesse Young, CTO of Telerivet, will demo their mobile messaging platform.
Nicolas di Tada will provide an overview of InSTEDD technology platforms.

Week 3
Ray Brunsting of the Tula Foundation will speak about their program in Guatemala.

Week 4
Mohini Bhavsar, a field manager with Dimagi, will discuss the Commcare platform.
Kelly Keisling, co-chair of the mHealth Working Group, will discuss groups and resources for individuals in the mHealth field.

We’re very excited to have over 45 participants enrolled from more than 12 countries representing organizations such as Doctors Without Borders/Medecins Sans Frontieres (MSF), Adcem Healthcare Limited, Catholic Relief Services, Chevron, Fistula Care Plus, Howard University, International Medical Corps, Jhpiego, Kuwait University Medical School, Mercy Corps, MIT, National Alliance of State & Territorial AIDS Directors, Office of the U.S. Global AIDS Coordinator, U.S. Dept. of State, Ottawa Hospital Research Institute, Plan International Canada, RTI, Temple Street Children’s University Hospital, University of Leeds, University of Michigan Health System, University of Notre Dame Masters of Global Health Program, University of South Carolina, University of Texas Medical Branch, VillageReach, and World Vision Malawi.
