Response Rates Impact Data Quality, But not How you Might ThinkStephanie Eckman
油
delivered at World Bank, part of Development Data Group Learning Series
Washington DC, 2016-03-07
Response rates do not always provide an accurate depiction of data quality. Research based on a large multi-country survey indicate that when interviewers play a substantial role in sample selection, interviewer manipulation may artificially generate high response rates. For example, when using the random walk selection technique, interviewers should select every kth household, but they have substantial leeway in deciding which household is the kth one, and may preferentially select those where someone is home. Or, when rostering a household to select a random respondent, interviewers may leave off household members who are seldom at home. If many interviewers engage is such behaviors, a high response rate may in fact be the result of biased sample selection and therefore indicate low data quality.
There are two lessons from these findings. First, response rates should not be used as the sole or primary proxy for data quality. Second, whenever possible, interviewers role in sample selection should be minimized. The talk concludes with a review of alternative sampling methods that take advantage of geospatial data such as satellite photos, drone imagery and handheld GPS devices. The ideal sampling techniques are ones that minimize interviewer discretion and allow for verification of interviewer performance.

How John started to like TDD (instead of hating it) - TED talkNacho Cougil
油
John, a typical developer, used to dread writing tests, finding them boring and unnecessary. Test Driven Development (TDD)? Even worsehe couldnt see how it worked outside of basic exercises. But something clicked. Through his journey, John discovered the magic of writing tests before the production code: fewer bugs, quicker feedback, and cleaner code. Now, hes hooked and wont code any other way. This is the story of how TDD turned a skeptic into a believer.
PS: Think of John as a random person, as if he was even the speaker of this talk !

Projects Panama, Valhalla, and Babylon: Java is the New Python v0.9Yann-Ga谷l Gu辿h辿neuc
油
Java has had a tremendous success and, in the last few years, has evolved quite significantly. However, it was still difficult to interface with libraries written in other programming language because of some complexity with JNI and some syntactic and semantic barriers. New projects to improve Java could help alleviate, even nullify, these barriers. Projects Panama, Valhalla, and Babylon exist to make it easier to use different programming and memory models in Java and to interface with foreign programming languages. This presentation describes the problem with the Java isthmus and the three projects in details, with real code examples. It shows how, combined, these three projects could make of Java the new Python.
