Workshop Recap: Introduction to High-Performance Computing (HPC)

On May 6 2024, Dr. Loris Bennett from FUB-IT at Freie Universität Berlin held the workshop Introduction to High-Performance Computing (HPC) at WI. In this workshop, he gave an overview of the mechanics of HPC and enabled participants to try it out themselves. While the workshop used the HPC cluster provided by FUB-IT as a practical example, most of the contents applied to HPC in general.

Dr. Bennett began with definitions of HPC and core concepts. He described HPC as a cluster of servers providing cores, memory, storage with high-speed interconnections. These resources are shared between users and distributed by the system itself. Users send jobs consisting of one or more tasks to the HPC cluster. Each task will run on a single compute server, also called a node, and can make use of multiple cores up to the maximum available on a node. The number of tasks per node can be set for each job, but defaults to one. Lastly, an HPC cluster may provide different file systems for different purposes. For example, the file system /home is optimized for large numbers of small files used for programs, scripts, and results, while /scratch is optimized for temporary storage of small numbers of large files.

Next, Dr. Bennett proceeded with resource management. When launching a job, many parameters can be set, such as the number of CPU and GPU cores, the amount of memory, and the time used. In order to determine the resources required for jobs, users need to run a few jobs and check what was actually used. This information can then be used to set the requirements for future jobs and thus ensure that the resources are used efficiently. The priority of a job dictates when a job is likely to start and depends mainly on the amount of resources consumed by the user in the last month. A Quality of Service (QoS) can be set per job which will increase the priority of a job, but the jobs within a given QoS will be restricted in the total amount of resources they can use. In addition, it is possible to parallelize tasks by splitting them into subtasks that can be performed simultaneously. Likewise, many similar jobs can be planned efficiently using job arrays.

Finally, participants could log into the FUB-IT HPC cluster themselves either using the command line or graphical interface tools and request first sample jobs. They were shown how to write batch files defining job parameters, use commands to submit, show, or cancel jobs, and check the results and efficiency of a completed job.

The Methods Lab would like to thank Dr. Bennett for his concise but comprehensive introduction to HPC!

Workshop Recap: Research Ethics – Principles and Practice in Digitalization Research

On April 18 2024, the Methods Lab organized the workshop Research Ethics – Principles and Practice in Digitalization Research to meet the increasing relevance and complexity of ethics in digitalization research.

In the first part of the workshop, Christine Normann (WZB) introduced participants to good research practice and research ethics in alignment with the guidelines of the German Research Foundation (DFG). Besides the need to balance the freedom of research and data protection, she informed about important institutions, noted the difficulties of formulating ethics statements for funding applications before study designs are finalized, and provided some practical tips regarding guidance when planning research.

Next, Julian Vuorimäki (WI) guided participants through the handling of research ethics at the Weizenbaum Institute. He focussed on the code of conduct, ombudspersons, guideline for handling research data, and the newly founded review board. The latter is in charge of providing ethics reviews for individual projects and studies, which can be applied for through a questionnaire on the institute website.

In the second part of the workshop, three researchers presented practical ethical implications and learnings from research projects. Methods Lab lead Christian Strippel reported on a study where user comments were annotated to allow for the automatic detection of hate speech. He focused on possible misuse for censorship, the confrontation of coders with questionable content, and the challenges of publishing the results and data regarding copyright and framing. Tianling Yang (WI) presented ethical considerations and challenges in qualitative research. The focus lied on consent acquisition, anonymity and confidentiality, power relations, reciprocity (i.e., incentives and support), and the protection of the researchers themselves due to the physical and emotional impact of qualitative field work. Finally, Maximilian Heimstädt (Helmut Schmidt University Hamburg) talked about ambiguous consent in ethnographic research. He gave insights into a study in cooperation with the state criminal police office to predict crime for regional police agencies. Not all individuals in this research could be informed about the research endeavor, especially when the researchers accompanied the police during their shifts, which raised the question of how to find a balance between overt and covert research.

The Methods Labs thanks all presenters and participants for this insightful workshop!

Workshop Recap: Introduction to Programming and Data Analysis with R

On April 10th and 11th, The Methods Lab organized the second edition of the workshop Introduction to Programming and Data Analysis with R. Led by Roland Toth from the Methods Lab, the workshop was designed to equip participants with fundamental R programming skills essential for data wrangling and analysis.

Across two days, attendees engaged in a comprehensive exploration of R fundamentals, covering topics such as RStudio, Markdown, data wrangling, and practical data analysis. Day one focused on laying the groundwork, covering the main concepts in programming including functions, classes, objects, and vectors. Participants were also familiarized with Markdown and Quarto, enabling them to include analysis results while producing text, and the key steps and techniques of data wrangling.

The first half of the second day was dedicated to showcasing and exploring basic data analysis and various visualization methods. Afterwards, participants had the opportunity to put into practice the knowledge they had gained from the previous day by working with a dataset to formulate and address their own research questions. Roland was on hand to offer assistance and guidance to the participants, addressing any challenges or concerns that arose along the journey.

The workshop fostered a collaborative learning environment, with lively discussions and ample questions from all. We thank all participants for their active involvement!

Workshop Recap: Introduction to Online Surveys

The use of online surveys in contemporary social science research has grown rapidly due to their many benefits such as cost-effectiveness and ability to yield insights into attitudes, experiences, and perceptions. Unlike more established methods such as pen-and-paper surveys, they enable complex setups like experimental designs and seamless integration of digital media content. But despite their user-friendliness, even seasoned researchers still face numerous challenges in creating online surveys. To showcase the versatility and common pitfalls of online surveying, Martin Emmer, Christian Strippel, and Roland Toth of the Methods Lab arranged the workshop Introduction to Online Surveys on February 22, 2024.

In the first segment, Martin Emmer provided a theoretical overview of the design and logic of online surveys. He started by outlining the common challenges and benefits associated with interviewing, with a particular emphasis on social-psychological dynamics. Compared to online surveys, face-to-face interviews offer a more personal, engaging, and interactive experience, enabling interviewers to adjust questions and seek clarification of answers in real time. However, they can be time-consuming and expensive and may introduce biases such as the interviewer effect. On the other hand, the process of conducting online surveys presents its own set of challenges, such as limited control over the interview environment, a low drop-out threshold, and particularities connected with self-administration such as the need for detailed text-based instructions for respondents. Nevertheless, self-administered and computer-administered surveys boast numerous advantages, including cost-effectiveness, rapid data collection, the easy application of visuals and other stimuli, and accessibility to large and geographically dispersed populations. When designing an online survey, Martin stressed the importance of clear question wording, ethical considerations, and robust procedures to ensure voluntary participation and data protection. 

In the second part of the workshop, Christian Strippel delved into the realm of online access panel providers, including the perks and pitfalls associated with utilizing them in survey creation. Panel providers serve as curated pools of potential survey participants managed by institutions, such as Bilendi/Respondi, YouGov, Cint, Civey, and the GESIS Panel. Panel providers oversee the recruitment and management processes, ensuring participants are matched with surveys relevant to their demographics and interests, while also handling survey distribution and data collection. While the use of online panels offers advantages such as accessing a broad participant pool, cost-efficiency, and streamlined sampling of specific sub-groups, they also have their limitations. Online panels are, for example, not entirely representative of the general population as they exclude non-internet users. Moreover, challenges arise from professional respondents such as so-called speeders who rush through surveys, and straight-liners who consistently choose the same response in matrix questions. Strategies to combat these issues include attention checks throughout the questionnaire, systematic exclusion of speeders and straight-liners, and quota-based screening. To conclude, Christian outlined what constitutes a good online panel provider, and shared valuable insights into how to plan a survey using one effectively.

The third and final segment of the workshop featured a live demonstration by Roland Toth on how to set up an online survey using the open-source software LimeSurvey, which is hosted on the institute’s own servers. During this live demonstration, he created the very evaluation questionnaire administered to the workshop participants at the end of the workshop. Roland began by providing an overview of the general setup and relevant settings for survey creation. Subsequently, he demonstrated various methods of crafting questions with different scales, display conditions, and the incorporation of visual elements such as images. Throughout the demo, Roland addressed issues raised earlier in the first part of the workshop concerning language and phrasing, emphasizing rules for question-wording and why it is important to ask for one piece of information only per question. The live demonstration was wrapped up with a segment on viewing and exporting collected data. After letting the participants complete the evaluation form, the workshop concluded with a Q&A session.
