Being There Live: An Ethnographic Approach for Studying Social Media Use in Mediatized Live Events

While live event experiences have become increasingly mediatized, the prevalence of ephemeral content and diverse forms of (semi)private communication in social media platforms have complicated the study of these mediatized experiences as an outsider. This article proposes an ethnographic approach to studying mediatized event experiences from the inside, carrying out participatory fieldwork in online and offline festival environments. I argue that this approach both stimulates ethical research behavior and provides unique insights into mediatized practices. To develop this argument, I apply the proposed methodology to examine how festival-goers perceive differences between public and private, permanent and ephemeral when sharing their live event experiences through social media platforms. Drawing on a substantial dataset containing online and offline participant observations, media diaries, and (short in situ and longer in-depth) interviews with 379 event-goers, this article demonstrates the value of an ethnographic approach for creating thick descriptions of mediatized behavior in digital platforms.

Being there live

Toward live domain-specific languages

Live programming is a style of development characterized by incremental change and immediate feedback. Instead of long edit-compile cycles, developers modify a running program by changing its source code, receiving immediate feedback as it instantly adapts in response. In this paper, we propose an approach to bridge the gap between running programs and textual domain-specific languages (DSLs). The first step of our approach consists of applying a novel model differencing algorithm, tmdiff, to the textual DSL code. By leveraging ordinary text differencing and origin tracking, tmdiff produces deltas defined in terms of the metamodel of a language. In the second step of our approach, the model deltas are applied at run time to update a running system, without having to restart it. Since the model deltas are derived from the static source code of the program, they are unaware of any run-time state maintained during model execution. We therefore propose a generic, dynamic patch architecture, rmpatch, which can be customized to cater for domain-specific state migration. We illustrate rmpatch in a case study of a live programming environment for a simple DSL implemented in Rascal for simultaneously defining and executing state machines.

Performance of human observers and an automatic 3-dimensional computer-vision-based locomotion scoring method to detect lameness and hoof lesions in dairy cows

The objective of this study was to determine if a 3-dimensional computer vision automatic locomotion scoring (3D-ALS) method was able to outperform human observers for classifying cows as lame or nonlame and for detecting cows affected and nonaffected by specific type(s) of hoof lesion. Data collection was carried out in 2 experimental sessions (5 months apart).

Stargazing Live!: Inspiring with semi-live astronomy data; teaching curriculum topics using smart education tools

Stargazing Live! aims to capture the imagination of learners with a combination of live and interactive planetarium lessons, real astronomical data, and lessons built around interactive knowledge representations. The lessons were created using a co-creation model and tackle concepts in the pre-university (astro)physics which students find difficult to grasp with traditional interventions. An evaluation study in 9 Dutch classrooms showed that learners are inspired and engaged by the planetarium lessons but are not always able to link the content to the classroom. Pre- and post-tests showed that the accompanying star properties activity significantly increased learners’ understanding of the causal relationships between mass and other properties (such as luminosity, gravity, and temperature) in a main sequence star.

Concurrent Validity Between Live and Home Video Observations Using the Alberta Infant Motor Scale

The purpose of this study was a serial assessment of gross motor development of infants at risk is an established procedure in neonatal follow-up clinics. Assessments based on home video recordings could be a relevant addition. In 48 infants (1.5-19 months), the concurrent validity of 2 applications was examined using the Alberta Infant Motor Scale: (1) a home video made by parents and (2) simultaneous observation on-site by a pediatric physical therapist. Parents’ experiences were explored using a questionnaire.
