Is Scholarly Use of R Beating SPSS Already?

One of us (Muenchen) has been tracking The Popularity of Data Science Software using a variety of different approaches. One approach is to use Google Scholar to count the number of scholarly articles found each year for each software. He chose Google Scholar since it searches "across many disciplines and sources: articles, theses, books, abstracts, and court opinions, from academic publishers, professional societies, online repositories, universities, and other web sites." Figure 1 shows the results from 1995 through 2016. Data collected in 2018 showed that while SPSS use dropped 39% drop from 2017 to 2018, its use was still 66% higher than R in 2018. Read More »

Is the US Healthcare System Suffering from the Dunning-Kruger Effect?

Psychologist David Dunning, originator of the eponymous Dunning-Kruger effect, recently gave an interview to Vox's Brian Resnick. For those of you not familiar with the Dunning-Kruger effect, it refers to the cognitive bias that leads people to overestimate their knowledge or expertise. More importantly, those with low knowledge/ability are most likely to overestimate it. Does this make anyone else think of the U.S. healthcare system? Professor Dunning proposed the effect in 1999, in a paper in Journal of Personality and Social Psychology, along with then-graduate student Justin Kruger. Since then, it has become widely known and broadly applied (not always accurately, as Dr. Dunning explains in the interview).

Open Education: There Isn't an App for That

Open source software has saved my district-Penn Manor School District in Lancaster County, Pennsylvania-more than a million dollars on its technology budget. But more importantly, making a deliberate and concerted effort to infuse open principles and practices into our learning environments has cultivated a vibrant and inclusive learning community that cuts across the school. And as a result, student success has exceeded our expectations. But how do schools put open ideas into practice to foster future innovators and leaders? It's not as simple as installing Linux on 4,000 student laptops, holding hands, and singing the alma mater in the high school cafeteria.

California’s Other Drought: A Major Earthquake Is Overdue

California earthquakes are a geologic inevitability. The state straddles the North American and Pacific tectonic plates and is crisscrossed by the San Andreas and other active fault systems. Tragic quakes that occurred in 2017 near the Iran-Iraq border and in central Mexico, with magnitudes of 7.3 and 7.1, respectively, are well within the range of earthquake sizes that have a high likelihood of occurring in highly populated parts of California during the next few decades. The earthquake situation in California is actually more dire than people who aren't seismologists like myself may realize. Although many Californians can recount experiencing an earthquake, most have never personally experienced a strong one. For major events, with magnitudes of 7 or greater, California is actually in an earthquake drought. Multiple segments of the expansive San Andreas Fault system are now sufficiently stressed to produce large and damaging events.

U.S. Healthcare Is a Cadillac...Unfortunately

The good news: the U.S. healthcare is a Cadillac. The bad news: it's not an Escalade or even an XTS, it's a Cimarron, which is on most experts' list not only of the worst Cadillacs ever but also the worst cars ever -- expensive and poor quality. It was literally a Chevy Cavalier dressed up and trying to pretend to be a luxury car. You probably get the metaphor. There was a time when "Cadillac" was essentially a synonym for quality. Products aspired to be "the Cadillac of ____." It was a compliment of the highest order, understood worldwide. Foreign auto manufacturers tried to match its quality and make a dent into its market share. There was a time with U.S. healthcare had that kind of status too.

Why Cloud for Health IT? Sharing our Experience at careMESH

If you want true, robust security, it is increasingly difficult to argue against cloud, given the advancements and growth in major service providers such as Google, Amazon, or Microsoft. No matter how many security staff members or how much cybersecurity experience you have, the major service providers have more. It's no surprise that across industries, investment in cloud computing, storage and infrastructure are predicted to grow at a rate of 17% annually over the next 3 years.[i]

Data Science Jobs Report 2019: Python Way Up, Tensorflow Growing Rapidly, R Use Double SAS

In my ongoing quest to track The Popularity of Data Science Software, I've just updated my analysis of the job market. To save you from reading the entire tome, I'm reproducing that section here.One of the best ways to measure the popularity or market share of software for data science is to count the number of job advertisements that highlight knowledge of each as a requirement. Job ads are rich in information and are backed by money, so they are perhaps the best measure of how popular each software is now. Plots of change in job demand give us a good idea of what is likely to become more popular in the future. Read More »

Mystery Consent Forms and the Scourge of Surprise Medical Bills

We are, it appears, shocked -- shocked! -- that there are "surprise" bills in healthcare. That is, bills from out-of-network healthcare professionals, even when patients thought they were going to in-network professionals/facilities. The problem is bad enough that even our deeply divided Congress has bipartisan agreement that it should act (although whether it will, of course, remains to be seen). Of course, surprise billing shouldn't come as a surprise to anyone who knows much about healthcare; it is more of a symptom of problems with our healthcare system than a problem itself. Kaiser Health News/NPR deserve much credit for getting more attention for the issue, with their Bill of the Month crowdsourced investigation.

Clinical Decision Support Strategies for Electronic Case Reporting and its Open Source Connection

A key element of public health surveillance is the reporting of infectious and certain non-infectious conditions to state, local, and tribal public health agencies (PHA) around the United States. Historically, there have been a number of key challenges with the process of case reporting that is pervasive in the United States today. To help overcome some of these barriers, an effort has been underway to move the process of case reporting to electronic. A key component of the emerging electronic care reporting (eCR) strategy is the use of clinical decision support (CDS) to help clinical care organizations determine if a reportable condition is present in a patient's record. Multiple approaches have been identified for this CDS service, including a centralized model being implemented today, and several distributed options which will likely become equally viable. Given the size, diversity, and decentralized nature of healthcare enterprises, it is likely that all three approaches for CDS discussed in this article will be deployed simultaneously.

Hydroelectricity and Transmission Planning in Chile Use Open Source Geospatial Tools

We were able to leverage a number of open source geospatial tools, such as QGIS, GDAL/OGR, and the PostGIS extension to the PostgreSQL open source relational database, in order to control the quality of the geospatial data at hand. These tools also helped us carry out the types of spatial analysis necessary to determine relationships between the various objects of value and, on the one hand, the potential hydropower projects, and on the other, the possible alternative transmission corridors. The key to hydroelectric capacity planning in Chile is the ability to generate the maximum amount of electricity, given certain restrictions, while assuring a fixed level of interaction with objects of value.
