#ESMARConf2025 is live now (https://www.youtube.com/@esmarconf), starting with a talk by @ASanchez_Tojar on "Practising what we preach: Rethinking standards in meta-analysis for ecology and evolution".
At 11am (CEST), I will give a talk on how to visualize the amount of heterogeneity in forest plots.
Together with colleagues from Spain, we recently conducted a comprehensive simulation study examining the performance of various types of tests and methods for constructing confidence intervals for the scale coefficients in meta-analytic location-scale models. Although things are complex, generally the likelihood-ratio test and corresponding profile-likelihood intervals performed best. See here for further details: https://doi.org/10.3758/s13428-025-02622-5
1/3 In a recent paper, we described the use of location-scale models in meta-analysis to not only examine how moderators may be related to the size of the effect, but also how moderators may be related to the amount of heterogeneity among the effects: https://doi.org/10.1002/jrsm.1562
Such models can be fit with the metafor package in R: https://wviechtb.github.io/metafor/reference/rma.uni.html#location-scale-models

Nice to see Georgia Salanti (@geointheworld) joining Mastodon. If you are interested in research synthesis and (network) meta-analysis, give her a follow! #MetaAnalysis #ResearchSynthesis
#ResearchSynthesis folks!
I created an R script to scrape #googleScholar search results to save you (and me) the tedious clicking.
Put in your search string and number of search results you need and get a csv. Use it, share it, improve it.

If you use AMSTAR 2 tool to assess many reviews in your study, check the {amstar2} package. It includes three easy-to-use functions:
1. amstar2_gtable()
2. amstar2_barplot()
3. amstar2_overall()

At this year's ZPID ressyn-bigdata.org symposium, we had most exciting keynotes on #BigData and #ResearchSynthesis in #psychology.
You can watch the videos here: https://zpid.cloud.panopto.eu/Panopto/Pages/Sessions/List.aspx#

At the http://ressyn-bigdata.org symposium this week we also had a fantastic and highly entertaining keynote by Rens van de Schoot on using ASReview to automate screening in systematic reviews. If you also want to save time and sanity, check out https://asreview.nl/

In our recent systematic review, we found that #MachineLearning yields a high potential to reduce screening time, especially for systematic reviews with many candidate papers.
The comparison of different tools under equal or at least similar conditions and for various data sets, as well as adequate rules for when to stop the manual screening, remain open questions.

🚨 Special announcement 🚨
The 4th Symposium on #BigData and #ResearchSynthesis in #Psychology is pleased to collaborate with Europe's Journal of Psychology (EJOP)!
Selected contributions from the symposium will be invited for full-text submission to a special thematic section of EJOP (https://ejop.psychopen.eu/).
💡 This year, we have a special focus on #MachineLearning and #OpenScience
⏰ The deadline for submitting structured abstracts is February 15, 2023
Our tutorial paper on methods to synthesize individual participant data obtained from complex sampling surveys is out in Psychological Methods.
If you work or are interested in working with International Large-Scale Assessment Data or National Data, this paper could provide you with new insights to analyze the data.

In the latest issue of #EcologyLetters former #PhDstudent Patrick Thomas summarises results from more than 100 experiments measuring #zooplankton growth and reproduction in response to food quality. A great baseline for our understanding of the producer-herbivore link in marine and freshwater ecosystems.

#Introduction time / shouting into the void with hashtags 😳
Currently a 3rd year #PhD student at Institute of Education, University College London ( #IoE #UCL 🇬🇧) Current research is #CorpusLinguistics looking at the language of suicidal ideation on social media.
I'm interested broadly in #DiscourseAnalysis and #HealthCommunication, particularly depression and suicide. Also #SystematicReviews and all things #ResearchSynthesis methodology.
Here's me presenting at #BAAL #HealthSci2022 yesterday
