2:11 PM | Lee Sechrest
Yesterday we posted on Lewis Richardson, a scientist who did pioneering work in weather prediction and, separately, in fractals, in the early twentieth century. I was pointed to Richardson by Lee Sechrest, who I then googled. Here’s Sechrest’s story: His first major book [was] “Psychotherapy and the Psychology of Behavior Change” . . . Sechrest […] The post Lee Sechrest appeared first on Statistical Modeling, Causal Inference, and Social Science.

5:09 PM | Scott’s “Art of not being governed,” in a nutshell
I read James Scott’s 2009 “The art of not being governed: An anarchist history of upland Southeast Asia.” I’ve reproduced a quote that concisely captures a nice chunk of the ~400 page book. The terms raw and cooked are Chinese euphemisms, possibly outmoded, for distinguishing between “barbarians” and “citizens.” It would seem to describe refinement, […]

2:43 PM | Lewis Richardson, father of numerical weather prediction and of fractals
Lee Sechrest writes: If you get a chance, Wiki this guy: I [Sechrest] did and was gratifyingly reminded that I read some bits of his work in graduate school 60 years ago. Specifically, about his math models for predicting wars and his work on fractals to arrive at better estimates of the lengths of common […] The post Lewis Richardson, father of numerical weather prediction and of fractals appeared first on Statistical Modeling, Causal Inference, and Social Science.

1:52 PM | Being Old in New York City
An article in this month's Politico magazine, "Seniors Take Manhattan," is all about the ways that it's easier to "age in place" in a big city than almost anywhere else in the U.S. The author, Debra Bruno, marshalls tons of evidence in defense of that position. read more

3:43 PM | When a study fails to replicate: let’s be fair and open-minded
In a recent discussion of replication in science (particularly psychology experiments), the question came up of how to interpret things when a preregistered replication reaches a conclusion different from the original study. Typically the original, published result is large and statistically significant, and the estimate from the replication is small and not statistically significant. One […] The post When a study fails to replicate: let’s be fair and open-minded appeared first on […]

1:22 PM | Cross-validation, LOO and WAIC for time series
This post is by Aki. Jonah asked in Stan users mailing list Suppose we have J groups and T time periods, so y[t,j] is the observed value of y at time t for group j. (We also have predictors x[t,j].) I’m wondering if WAIC is appropriate in this scenario assuming that our interest in predictive accuracy is for […] The post Cross-validation, LOO and WAIC for time series appeared first on Statistical Modeling, Causal Inference, and Social Science.

10:12 PM | Springer and Macmillan merger : some observations
The proposed merger between Springer and Macmillan came as a surprise to me. They are two big brands that come together. However if you look purely at figures in number of journals Macmillan is a midget compared to Springer and combined they are probably slightly bigger than Elsevier. It is the brand of Nature and … Continue reading Springer and Macmillan merger : some observations The post Springer and Macmillan merger : some observations appeared first on WoW! Wouter on the Web.

2:30 PM | Psychological Theory and Gamification of Learning
Gamification, the use of game elements in non-game contexts, is increasingly being implemented in both student and organizational learning initiatives. Many of these efforts are atheoretical, meaning that the teachers using them don’t necessarily have a well-grounded reason for gamifying. Instead, they often gamify with the intention of making learning more “fun.” Unfortunately, 1) not […]The post Psychological Theory and Gamification of Learning appeared first on […]

The purpose of this study was to examine the beliefs that teachers have about diversity and their level of sensitivity towards some topics related to it. Moreover, beliefs were compared according to teachers’ personal and professional views and teaching experience. The Personal and Professional Beliefs about Diversity Scales (Pohan and Aguilar, 1999) were administered to a sample of 233 teachers. Results showed highly positive beliefs towards diversity in all its dimensions (cultural, […]

11:00 PM | An Attack on Inclusive Education in Secondary Education. Limitations in Initial Teacher Training in Spain
Inclusive education is hard to implement in secondary schools. Probably, one of the determining factors lies in teachers' initial  training that determines their attitude, identity and professional practice. This research analyses the initial teacher education programmes for Secondary Education, Higher Secondary Education, called bachillerato in Spain, and Vocational and Artistic training in the five best valued Spanish universities in the education field, according to the ranking I-UGR, […]

11:00 PM | Determinants of Internet use for interactive learning: an exploratory study
The use of the Internet in higher education teaching can facilitate the interactive learning process and thus improve educational outcomes. The aim of the study presented here is to explore which variables are linked to higher intensity of Internet-based interactive educational practices. The study is based on data obtained from an online survey of students from three different types of universities: a face-to-face university (University of Barcelona, UB), a technological face-to-face […]

9:10 PM | Egg yolks as design feature
I have more trouble than I should remembering how many cups of flour I’ve put in the batter so far, but I never have trouble remembering the number of eggs, because each egg comes with a yellow token to help in keeping count. I’d say egg’s are pretty well designed, although, to be fair, a […]

10:58 AM | In the era of #repligate: What are valid cues for the trustworthiness of a study?
In a recent lecture I talked about the replication crisis in psychology. After the lecture my students asked: “We learn so much stuff in our lectures, and now you tell us that a considerable proportion of these ‘facts’ probably are just false positives? Then, what can we believe at all?”. A short discussion soon led […]
