En este taller introductorio vamos a acercarnos a la **Teoría de Respuesta al Ítem (TRI)** de una manera práctica y accesible. La TRI sirve para entender mejor **cómo funcionan los ítems (preguntas) de un test y cómo miden una habilidad o rasgo**. Nos permite ver, por ejemplo, si un ítem es más fácil o más difícil, si discrimina bien entre personas con distinto nivel, y si funciona de manera consistente. También es una herramienta muy útil para seleccionar los mejores ítems, acortar tests sin perder calidad y diseñar escalas más precisas. A lo largo del encuentro, vas a: \- Construir una comprensión conceptual de sus ideas principales\. \- Aplicar este método usando R\. \- Aprender a interpretar sus resultados para entender mejor cómo funcionan los ítems y qué aportan a la medición\. Este taller es **introductorio** y está dirigido a personas con un **conocimiento básico de escalas psicométricas**. **No requiere conocimiento previo de Teoría de Respuesta al Ítem.** **Requerimientos:** * R: 4.5.1 (mínimo) * RStudio: 2025.05.1 (mínimo, descargar [aquí](https://posit.co/downloads/)) * Instalar los paquetes **tidyverse, mirt y ltm**

🇪🇸Español Abajo 👇 Did you move to a new country and have to reinvent yourself? Building friendships from scratch, navigating a new language, missing home — yet longing to belong? Argentine Tango was born from exactly these stories. In Buenos Aires, generations of newcomers found connection in an unfamiliar land — through an improvised embrace, without fixed rules, simply listening and responding to one another. 🔹 **What to expect?** ✔️ Discover tango as a social language — not just a dance ✔️ Playful, guided partner exercises to explore connection through movement ✔️ The embrace, the walk, and the subtle dialogue that arises between two bodies ✔️ No pressure with complicated sequences - two left feet are welcome! 📍 **Where?** "La Casona de los Bellos Aires" in Rawson 394. We’ll walk together from Tienda del Cafe Italiano to the tango space (easy to combine with the Culture Shock Therapy social gathering before) 💰 **How much?** 10.000$ 🙋🏼‍♀️ **Who?** Guided by Valerie Kattenfeld — tango dancer and teacher, passionate about creating warm, clear, and authentic spaces for connection through dance. 👟 **What to bring?** Comfortable clothes and shoes you can move in (sneakers or sandals you can close. No Flip Flops. Also socks are ok). You do not need to come with a partner. ☕ **Before?** Join our Culture Shock Therapy social meetup at Tienda de Café and come with us to the class! Step into a living piece of Buenos Aires — and maybe recognize a part of your own story in the embrace. ✨ See you on the dance floor! FOLLOW US INSTAGRAM: @CULTURE.SHOCKTHERAPY / @valeriekattenfeld [Instagram](https://www.instagram.com/culture.shocktherapy/) *** ¿Te mudaste a otro país y tuviste que reinventarte? ¿Construir amistades desde cero, manejarte en otro idioma, extrañar tu hogar — y al mismo tiempo sentir el deseo de pertenecer? El Tango Argentino nació exactamente de esas historias. En Buenos Aires, generaciones de recién llegados encontraron conexión en una tierra desconocida — a través de un abrazo improvisado, sin reglas fijas, simplemente escuchando y respondiéndose mutuamente. 🔹 **¿Qué podés esperar?** ✔️ Descubrir el tango como un lenguaje social — no solo como un baile ✔️ Ejercicios lúdicos y guiados en pareja para explorar la conexión a través del movimiento ✔️ El abrazo, la caminata y el diálogo sutil que surge entre dos cuerpos ✔️ Sin presión ni secuencias complicadas — ¡bienvenidas las personas con dos pies izquierdos! 📍 **¿Dónde?** "La Casona de los Bellos Aires" in Rawson 394. Caminaremos juntas/os desde Tienda del Cafe Italiano hasta el espacio de la clase (fácil de combinar con el encuentro social previo de Culture Shock Therapy). 💰 **¿Cuánto?** 10.000$ 🙋🏼‍♀️ **¿Quién?** Guiado por Valerie Kattenfeld — bailarina y profesora de tango, apasionada por crear espacios cálidos, claros y auténticos de conexión a través de la danza. 👟 **¿Qué traer?** Ropa cómoda y calzado con el que puedas moverte (zapatillas o sandalias que se puedan cerrar. No ojotas. También podés venir en medias). No necesitás venir en pareja. ☕ **¿Antes?** Sumate al encuentro social de Culture Shock Therapy en Tienda de Café y venite con nosotras/os a la clase. Entrá en una pieza viva de Buenos Aires — y quizás reconozcas una parte de tu propia historia en el abrazo. ✨ ¡Nos vemos en la pista! **SEGUINOS** **INSTAGRAM: @CULTURE.SHOCKTHERAPY / @valeriekattenfeld** [Instagram](https://www.instagram.com/culture.shocktherapy/)

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!
