This works great, but for blogdown we’ll start using Netlify. Let’s start RIGHT NOW with a site we’ve already built and published. Pre-requisites Pick either your postcards site, or your distill site from day 01. Refresh your memory- which repository was it again? /blog/spoonful-series/01-spoonful/ Fri, 01 Jan 2021 00:00:00 +0000 /blog/spoonful-series/01-spoonful/ Hi, I'm the here-bot cat!

But the way we see it—the photos, graphics, and videos that circulate in the media—shapes how we understand the problem, how we feel about it, and what actions we take. This project explores how climate change is visualized in the media and research, highlighting emerging trends, blind spots, and future directions. /talk/liverpool25/ Tue, 24 Jun 2025 00:00:00 +0000 /talk/liverpool25/ The Presentation: /talk/comptext25/ Thu, 24 Apr 2025 00:00:00 +0000 /talk/comptext25/ Abstract: Large language models (LLMs) are widely used as research tools, but their highresource demands raise significant environmental concerns. While LLMs offer advan-tages in certain applications, their high energy demands prompt a necessary questionfor social scientists: Is it worth considering LLMs for every text analysis task? Thisstudy systematically evaluates the trade-off between performance and energy usageacross computational text analysis methods, including dictionaries, trained classifiers,and open “local” LLMs. Applying sentiment analysis, multi-class classification, andnamed entity recognition to political documents, we measure energy consumption,CO2emissions, correlation with human raters, F1-Score and processing time. /project/emissiontracker/ Sun, 30 Mar 2025 00:00:00 +0000 /project/emissiontracker/ 📦 emissionTrackerR emissionTrackerR is an R package that helps track, log, and visualize carbon emissions generated by your R code, ML experiments, and projects. It supports automatic logging, metadata collection, real-world emission equivalents, and a built-in Shiny dashboard. It is inspired by and conceptually based on the Python package CodeCarbon developed by ML CO2 Impact, and aims to bring similar functionality to the R ecosystem. 🚀 Installation # Install from GitHub devtools::install_github("your-username/emissionTrackerR") 🔧 Basic Usage library(emissionTrackerR) # Track emissions for a code block track_emissions_for("example_sleep", { Sys. /talk/bremen24/ Wed, 20 Nov 2024 00:00:00 +0000 /talk/bremen24/ Abstract: The integration of Artificial Intelligence (AI) into visual communication, particularly within climate change debates, shows a key change in how public discourse is influenced by media (Chian & Lee, 2023; Krishnan et al., 2023). Simultaneously, manipulated images pose a misinformation risk when viewers cannot determine the credibility of what they see (He, 2021). We focus on the polarized topic of climate change to explore how manipulated images shared on Twitter may contribute to polarizing debates between believers and sceptics (deniers) in anthropogenic climate change. /talk/lmu2024/ Tue, 22 Oct 2024 00:00:00 +0000 /talk/lmu2024/ My Presentation: /talk/exeter24/ Wed, 26 Jun 2024 00:00:00 +0000 /talk/exeter24/ Summary: The Centre for Climate Communication and Data Science (C3DS) hosted a seminar on June 26th, 2024, featuring Isaac Bravo from the Technical University of Munich, Germany. Bravo presented his research on the “Visual Framing of Climate Change Imagery on Twitter.” The hybrid seminar was held both in person at the University of Exeter’s Streatham Campus and online via Zoom. Bravo’s research delves into how the framing of climate change imagery on social media platforms like Twitter influences people’s emotional engagement with the issue. /talk/campfire/ Thu, 06 Jun 2024 00:00:00 +0000 /talk/campfire/ Abstract: The emergence of Artificial Intelligence (AI) models is reshaping how scientists interact with this technology when conducting research. This has led to a growing interest in the role and impact of AI in the field of scientific communication over the last few years (Schäfer, 2023). The benefits of this technology that we can find as researchers are varied (Chian & Lee, 2023; Krishnan et al., 2023). Simultaneously, manipulated images pose a misinformation risk when viewers cannot determine the credibility of what they see (He, 2021). /talk/comptext24/ Thu, 02 May 2024 00:00:00 +0000 /talk/comptext24/ Abstract: This study explores the effects of manipulated visual content on polarized climate change debates on Twitter by answering the following research question: Do ‘real’ vs manipulated images about climate change on Twitter lead to different levels of engagement and interactions between believers and skeptics (deniers)? In this research, we analyse the intersection of social science and computer science in the context of climate change discourse on Twitter by adopting a multimodal and computational approach combining automated image and text analysis to examine more than 700,000 images, and replies shared by Twitter users in the year 2019. /talk/eufeels2023/ Wed, 27 Sep 2023 00:00:00 +0000 /talk/eufeels2023/ Abstract: How and to what extent do frames of climate change imagery on social media affect people’s emotional engagement with climate change? How does this vary across different regions across the world where the adverse effects of climate change are expressed differently? Previous studies have focused on a small selection of the most iconic images of climate change, primarily using qualitative methods and data from Western countries. While there are a few comparative studies that contrast how people engage with this phenomenon across countries, we adopt a computational approach that combines framing theory with automated image and text analysis to analyse millions of images, tweets and responses shared by Twitter users during 2019 - 2022. /talk/wapor2023/ Tue, 19 Sep 2023 00:00:00 +0000 /talk/wapor2023/ Abstract: Climate change is a global phenomenon with multidimensional and widespread consequences, which has received considerable media attention in recent decades. Climate change is considered one of the most important challenges faced by the world not only in the present but also in the future. Both scientific and political communities have recognized the urgency of addressing the impacts of this phenomenon, and understanding how people perceive and engage with it. /project/textanalizer/ Mon, 21 Aug 2023 00:00:00 +0000 /project/textanalizer/ 📑 TextAnalizeR The Text Analyzer Shiny App is an interactive tool for analyzing and visualizing text data. It allows users to perform various text analysis tasks, including sentiment analysis, word frequency analysis, and topic modelling. This README provides an overview of the app’s features, how to use it, and how to get started. This app focuses on making life easier for researchers looking to explore insights in their text analysis. /talk/lmu2023/ Wed, 21 Jun 2023 00:00:00 +0000 /talk/lmu2023/ My Presentation: /talk/tumevent2023/ Fri, 27 Jan 2023 00:00:00 +0000 /talk/tumevent2023/ The Poster Event: /blog/social/ Thu, 28 Jan 2021 00:00:00 +0000 /blog/social/ There are five places where you can choose to show social icons. Here is the tl;dr: site header (set in config.toml), site footer (set in config.toml), homepage (set in content/_index.md), about page in the sidebar (set in content/about/sidebar/index.md), and contact page (set in content/form/contact.md). Read on to learn how to set up your social icons, and how to show/hide them. Configure social Wherever you end up wanting to show your social icons, you’ll need to start by setting up the links in your site config. /blog/color-themes/ Wed, 27 Jan 2021 00:00:00 +0000 /blog/color-themes/ You can totally customize your site’s theme colors within minutes of creating a new site. Read on to find out how, and decide which of the three options meets your needs. Use a color theme Hugo Apéro includes 8 built-in color themes that work “out of the box.” This means you can use a color theme to quickly customize the look of your site without needing to write any CSS. You can select the color theme in your config. /blog/fonts/ Wed, 27 Jan 2021 00:00:00 +0000 /blog/fonts/ As with color themes, you can completely customize your site’s fonts within minutes of creating a new site. How you do it depends on how much control and customization you need. Embedded fonts Hugo Apéro includes 6 embedded fonts that work “out of the box.” We selected 3 serif and 3 sans-serif options that we thought looked good with this theme, in our humble opinions. All embedded fonts include real italics so you may emphasize to your heart’s content ❤️! /blog/evergreen/ Wed, 20 Jan 2021 00:00:00 +0000 /blog/evergreen/ Rendering mathematical equations Examples from the mathjax demo. But they work with katex as well. Rmarkdown In .Rmarkdown documents, you can use either $a \ne 0$ to get inline math: \(a \ne 0\). There is no conflict with using dollar symbols regularly, because knitr automatically escapes freestanding dollar symbols. And you can use $x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$ to get a math paragraph: $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}. /blog/seedling/ Sat, 02 Jan 2021 00:00:00 +0000 /blog/seedling/ Courtesy of panelset.js by Garrick Aden-Buie, from his xaringanExtra package: https://pkg.garrickadenbuie.com/xaringanExtra/#/panelset For example, this panelset: Hello! 👋 hello Goodbye 💨 goodbye Was created by combining this theme’s panelset and panel shortcodes: {{< panelset class="greetings" >}} {{< panel name="Hello! :wave:" >}} hello {{< /panel >}} {{< panel name="Goodbye :dash:" >}} goodbye {{< /panel >}} {{< /panelset >}} You could also revert to HTML as well.
