Snippets Of The Covid-19 Scenario in Africa

May 11, 2020
STATE OF PLAY

As of May 8th, 12 pm PT, the Africa Centers for Disease Control and Prevention (Africa CDC) Dashboard reported a cumulative of 54,434 confirmed COVID-19 cases, 2,080 deaths, and 18, 857 recoveries. The first case from the African continent was reported on 14 February 2020 in Egypt. Eighty percent of Africa’s cases are accounted for by 10 countries with widespread transmission in seven of them. Generally, the five hardest-hit countries include South Africa, Algeria, Nigeria, Ghana, and...

Organized Code Repositories Accelerate Science and Facilitate Reproducubility

March 2, 2021

Computational and data-driven research increasingly requires developing complex codebases. At the same time, many scientists don’t receive training in software engineering practices, resulting in, for some, the perception that scientists write terrible software. As scientists, good software should accelerate our work and facilitate its reproducibility. While building good coding practices takes some time and experience, it doesn’t require a...

Handling Missing Data

May 4, 2021

I recently started working with a set of eviction data for a project on housing precarity at the Urban Displacement Project. As I began exploring the dataset, I was excited to find that it appeared to contain a wealth of historical data we could use to train a robust model for predicting eviction rates in urban neighborhoods. However, my initial excitement soon had to be scaled back when a standard check for missing data revealed that many of the observations lacked values for precisely the variable we aimed to predict. I was now faced with the problem of what to do about this...

Improving Research Transparency in the Social Sciences through Pre-Analysis Plans

March 23, 2021

Openness, transparency, and reproducibility in research are critical to scientific progress. Yet, according to a 2016 internet-based survey of 1,576 researchers, 90% of respondents felt there was a slight or significant reproducibility crisis.1 Moreover, there are longstanding concerns that scientific journals favor positive or significant results—often referred to as publication bias—which may produce bodies of evidence that are incomplete or misleading (i.e., because studies which report null findings are not published).2 Publication bias can also arise when researchers choose...

Exploring The Oakland Area Through Data

March 10, 2020

A project that uses many tools that are taught at the D-Lab, and on which I’m excited to be working with students, focuses on exploring the city of Oakland, CA through spatial data.

WHY DO I FIND THIS INTERESTING?

One project that I’ve been working on with a student (CS major, ERG minor) is the exploration of environmental justice and transportation in the City of Oakland, CA.

It’s really cool to get to know our neighboring city by exploring the multiple data sets available, and then being able to walk through those spots that...

Data and Tools for Mapping COVID-19

April 28, 2020

Since the early days of the COVID-19 crisis (the past few months!), the spatial and temporal enormity of the situation has been tellingly conveyed in mapped data visualizations. The most compelling maps, in my opinion, have been those created by the New York Times ….

Manuscript Workflow with R Markdown and GIT

March 16, 2021

As part of my Masters of Public Health program I needed to complete a capstone. Working on a manuscript is a lot of back and forth: You need to make edits, fix your words and figures, and sometimes re-work entire sections. If you are like me, the thought of doing this process over a long period of time in Word makes me nauseous. Two main issues that cause this nausea for me are:

I frequently forget to make a record of my writing and often overwrite work

Copying and pasting figures while arguing with Word’s formatting...

The Pressure to be Productive Amidst Reigning Chaos

April 14, 2020

After more than two weeks following the shelter in place guidelines, I have developed some sort of a routine. That is the only way I can get myself to do any work. As a graduate student, I feel the pressure to be productive even in the middle of a pandemic. My most productive hours usually occur between 7am and 2pm. I have never tried to understand why that is the case. However, since being confined to my apartment, I have been unable to work at the same level of efficiency even during my golden hours.

Some investigation into this lack of productivity has led me to realise that my...

Howdy Neighbor! Proximity Analysis in R

March 1, 2021

Proximity analysis is one of the cornerstones of spatial analysis. It refers to the ways in which we use spatial methods to ask "what is happening near here". It is at the heart of the Tobler's first law of geography which I paraphrase as "Everything is related but near things are more related." In practice, proximity analysis...
