Purchasing Glass

20 06 2013

The following images, in chronological order, document my purchase of a Google Glass device. I have covered up one or two personal details, so not everything is shown. Google has developed what I considered to be an elegant and simple purchasing system. I hope this experience continues once I receive the device.





Google Glass Invite

For those of you waiting to receive notification about when you can purchase your Google Glasses, it should look something like this if you applied for the Glass Explorer program through Google+. Once I have the device up and running in the next month or so, I will start sharing my experience with using the technology to transform the way I teach my seminar on sustainable development.

The Fieldwork Begins!

11 06 2013

After two weeks of intensive training and a successful pilot study, the fieldwork for the follow-up study of the MCA’s rural water program in Nampula, Mozambique, began on Monday (June 10). As the fieldwork progresses over the next seven weeks, the surveying teams will undertake household surveys, water committee interviews, water point observations, technical assessments, and water source/storage testing, among other activities.

SAM_3627As usual, the pilot study proved to be an invaluable way to learn where the surveyors and team leaders required additional training and where our support team (consisting of researchers and staff from Virginia Tech, Stanford, and WE Consult) needed to provide additional support or rethink existing standard operating procedures (SOPs). The logistics associated with this project are complex and not only involve the careful programing of when and where the field teams will be over time, but also managing tasks such as how the 1,800 water samples will be transported for processing and where this processing will occur – i.e., in the field or back in our base camp. We also plan to collect water source samples in four communities at four different times during the day on three different occasions to check for variability in the quality of water over time. This type of water source testing will add a new dimension to our study and help identify whether the quality of water in these communities changes over a period of around six weeks. Another new dimension in the follow-up study is that the surveyors will use GPS devices to find the households we interviewed back in 2011. I will report back later on how successful they were at finding these households.

From a data quality perspective, we continue to advance and refine our data review and cleaning processes with our on-the-ground statistician (Marcos Carzolio). This year we are leveraging secure data transfer technology to enable the research team to view the data from any location in the world as soon as it is available. This platform also enables the lead researchers to communicate with the fieldwork team leaders as they upload the data in remote rural areas.

While the household survey is administered using PDAs, making the data easily accessible, the remaining surveying instruments are paper-based and require a different data entry and review process. This task will be managed by our in-country partner (WE Consult) given the need to have native Portuguese speakers managing the process.

In the next week, a fourth surveying team will leave Nampula and travel to Cabo Delgado to begin a study of eight small piped solar systems that have been constructed by the MCA. This more qualitative study will attempt to identify those factors supporting or limiting the successful delivery of water services via these systems. The Cabo Delgado team will be led by Emily Van Houweling (Virginia Tech) who spent a year in Mozambique as a Fullbright scholar last year while completing her doctoral research.

The above description should provide some insight into the many moving parts of this large-scale study, which is providing our team with plenty of challenges, but is also proving to be a highly rewarding experience for all involved. While our primary objective is to undertake an impact evaluation for the MCC, we hope our data will be of real value to the provincial and national governments of Mozambique and to the international community when making decisions about how to invest in sustainable rural water and sanitation services in the country.

The images below were taken during our final week of training and the pilot study.

Update from the Field

1 06 2013

I started writing this post a week ago while flying from Maputo to Nampula in Mozambique, but the usual challenges of setting up a large-scale research project delayed my intentions. One challenge is finding/installing a good Internet connection, which we overcame by purchasing a number of Movitel USB modems that are working surprisingly well.

I’m in Nampula with a team of researchers from Virginia Tech (Eric Vance, Emily Van Houweling, and Marcos Carzolio), Stanford University (Jenna Davis and Kory Russel), and WE Consult (our in-country partner) to undertake a follow-up study for an evaluation of the Millennium Challenge Corporation’s rural water program in the province. We undertook the baseline study in 2011 and plan to complete the follow-up study over the next two months.

Over the past week, we have begun our enumerator training that has focused primarily on reviewing each module of the household survey (which consists of more than 600 questions that will be navigated using logic) and practicing skills such as how to measure a child and use GPS devices (that are needed to find the same households we surveyed in 2011). Next week we will continue to refine the various surveying instruments with the enumerators (who are mostly local to Nampula) and begin practicing how to take water samples, among other activities. We will soon select our team leaders from the twenty enumerators we are training, who will each receive specific training on the various research protocols we will be using.

We have established a base camp in a house in the city of Nampula, which is proving to be a pleasant place to work/live, even if there is no water most days. There are several major construction projects happening in the city that have severely constrained the water supply that only comes once a day for several hours if we are lucky.

I have included some pictures below of the activities so far. I will post some more following the pilot study that is planned for later next week.

The Drama of Human-Technology Interaction

18 04 2013

Imagine you are sitting at your computer (which you are) and are about to complete a task such as such writing an email to a friend or analyzing some data using a spreadsheet. Such tasks would seem rather routine, but through the eyes of Brenda Laurel, they might be conceived as subplots in the drama of life. In “The Six Elements and the Causal Relations Among Them” and “Dramatic Interaction in a Small World,” Laurel considers how human-technology interactions could be conceived in theatrical terms. By using Aristotle’s sixth elements of structure in drama (below), Laurel takes us on a thought exercise in how drama can be used to describe the elements of human-computer interaction. While I have yet to be convinced of the inherent value of the framework, the notion that our interaction with technology can be thought of as an “organic whole” – where “form and structure can approach that of natural organisms in the way the parts fit perfectly together” (p. 570) – does provide a vision for a perfect human-technology symbiosis.

If my interaction with a computer can be thought of in a theatrical way, my question is who is writing the script? I’d like to think that I control the script and that the computer enables my acting by perfectly responding to, perhaps anticipating, my every move in a free flowing form of interaction. At some level this is true. For example, my computer just told me that I misspelt “ineraction.” However, it is also true that my interaction with a computer is constrained by the limitations of the computer and its programs. This makes me wonder whether the very structure of a computer platform will dictate, at a meta-level, the scope of the script and the drama that unfolds. One is reminded of “the architect” in the Matrix and whether the writers of that script were on to something.





Leveraging Statistics to Improve Data Quality

In the video below, Eric Vance and I are joined by several of our graduate students to describe how we developed the concept of an “on-the-ground statistician” to advance our data collection and cleaning practices in relation to large-scale household surveys.
