\u3010\u30bf\u30a4\u30c8\u30eb\u3011A practical introduction to word embedding techniques – and why social scientists should be interested in them<\/p>\n
\u3010\u8981\u65e8\u3011This seminar is divided in two parts. In the first one (held in 9:00-10:30 entitled \u201c(Theory): Moving beyond the bag-of-words approach: Word Embeddings\u201d), I will give an introduction to word embedding (WE) techniques, focusing in particular on GloVe (Global VEctors of words). The aim is a) to present the main ratio behind word embedding models; b) to explain why social scientists should care about them (as a method on their own for analyzing text as data – for example for studying word usage, meaning, stereotypes, but also as useful complements to other algorithms, such as machine learning algorithms, dictionaries, and so forth); and c) to give some advices to practitioners. The second part of the seminar (16:30-18:00 entitled \u201c(Lab): How to implement Word Embeddings\u201d) will offer a hands-on lab on how to fit a GloVe in R. A general knowledge of R (in particular of the Quanteda package) would be useful, as well as a general familiarity with machine learning algorithms.<\/p>\n

\u3010\u30bf\u30a4\u30c8\u30eb\u3011Covid Policy Diffusion among OECD Countries: when it happened, and when it did not<\/p>\n
\u3010\u8981\u65e8\u3011To address the Covid pandemic, a set of unprecedented Non-Pharmaceutical Interventions were implemented across the world. We document patterns of policy diffusion across OECD countries in the period January 2020 to March 2022. By performing a diffusion analysis with spatially-weighted lags, we find evidence of a discernible association between policies adopted across OECD countries according in particular to their geographical proximity. Interestingly, we find that policy diffusion effects are stronger when other countries are, on average, increasing the stringency of the restrictions they adopt. Conversely, no statistically significant policy diffusion can be detected when other countries are relaxing their restriction. We suggest that this asymmetry, leading to biased diffusion, reflects political incentives linked, among other things, to the variance of the quality of governance across countries. We finally consider the implications of our findings.<\/p>\n","protected":false},"excerpt":{"rendered":"
