Earthquake Data

Abstract The Southern California Earthquake Data Center is hosting its earthquake catalog and seismic waveform archive in the Amazon Web Services (AWS) Open Dataset Program (s3://scedc-pds; us-west-2 region). The cloud dataset’s high data availability and scalability facilitate research that uses large volumes of data and computationally intensive processing. We describe the data archive and our rationale for the formats and data organization. We provide two simple examples to show how storing the data in AWS Simple Storage Service can benefit the analysis of large datasets. We share usage statistics of our data during the first year in the AWS Open Dataset Program. We also discuss the challenges and opportunities of a cloud-hosted archive.

Abstract The 2019 Mw 6.4 and Mw 7.1 Ridgecrest earthquake sequence occurred in the eastern California shear zone (ECSZ). The mainshock ruptured the Little Lake fault zone, and aftershocks extended from the Garlock fault in the south to the southern end of the 1872 M 7.5 Owens Valley earthquake rupture in the north. We present data from the Southern California Seismic Network (SCSN) and partner seismic networks recorded by the SCSN in the region. These time-series data and related products such as the SCSN earthquake picks and catalogs, available from the Southern California Earthquake Data Center, provide the most comprehensive seismic datasets for the 2019 Ridgecrest earthquake sequence.

This review discusses early diagnostics and early intervention in developmental disorders in the light of brain development. The best instruments for early detection of cerebral palsy (CP) with or without intellectual disability are neonatal magnetic resonance imaging, general movements assessment at 2–4 months and from 2–4 months onwards, the Hammersmith Infant Neurological Examination and Standardized Infant NeuroDevelopmental Assessment. Early detection of autism spectrum disorders (ASD) is difficult; its first signs emerge at the end of the first year. Prediction with the Modified Checklist for Autism in Toddlers and Infant Toddler Checklist is possible to some extent and improves during the second year, especially in children at familial risk of ASD. Thus, prediction improves substantially when transient brain structures have been replaced by permanent circuitries. At around 3 months the cortical subplate has dissolved in primary motor and sensory cortices; around 12 months the cortical subplate in prefrontal and parieto-temporal cortices and cerebellar external granular layer have disappeared. This review stresses that families are pivotal in early intervention. It summarizes evidence on the effectiveness of early intervention in medically fragile neonates, infants at low to moderate risk, infants with or at high risk of CP and with or at high risk of ASD.

The fast transition to fully online studies due to the pandemic made the universities around the world question many of their accepted notions on teaching foreign languages in general and English for Specific Purposes (ESP) methodology in particular. Putting stress on the synchronous remote teaching and learning has proven to yield a reductionist perspective missing asynchronicity, the dimension which makes reconsider the whole educational process. With its shift from the sole focus on learning terminology to training skills in authentic professional contexts, the task-based approach has long excelled in meeting the diverse needs of students. Thus, the research question is how well task-based teaching (TBT) solves the problems raised with asynchronous learning in a university ESP course. The research of available literature on TBT yielded the framework for constructing an extended task applicable in the advanced medical English. The case study with 120 first-year students of medicine organised around an informational interview with health professionals demonstrated easy adaptability of the task to the asynchronous nature of the educational process. Personal observations by the course instructor, summaries of student-conducted interviews, and student written feedback proved the responsiveness of the method to the learners’ needs and the potential of the approach in terms of motivation. The emphasis on self-directed learning, however, threatens the systematicity of the acquired language skills, as a more controlled teaching environment would not allow “skipping” any learning step. Additionally, TBT does not solve the problem of the voluminous teaching load.

Replication is an important technique in peer-to-peer environment, where it increases data availability and accessibility to users despite site or communication failure. However, determining the number of replication and where to replicate the data are the major issues. This paper proposes a hybrid replication model for fixed and mobile network in order to achieve high data availability. For the fixed network, a data will be replicated synchronously in a diagonal manner of logical grid structure, while for the mobile network, a data will be replicated asynchronously based on commonly visited sites for each user. In comparison to the previous techniques, diagonal replication technique (DRG) on fixed network requires lower communication cost for an operation, while providing higher data availability, which is preferred for large systems.

Challenges And Opportunities

Many university libraries hold cultural heritage collections that are unknown to the majority of students. The digitisation of these collections offers new ways of working with primary sources, and with it, an increasing interest in archives and older collections. This development has made us reflect on our information literacy classes within the humanities. Are we too influenced by the STEM and social science interpretations of information literacy and their focus on the peer-reviewed article? We want to challenge this view and discuss what a humanities approach to information literacy could incorporate.We want to invite you to a discussion on how we can integrate archival material and other primary sources into our classes,thus broadening mainstream information literacy to include primary source literacy (see ACRL’s Guidelines for primary source literacy, 2018). Our understanding is that this topic is generally not discussed at Nordic information literacy conferences, and our literature review indicates that this field is mostly addressed by special collections librarians and archivists (Hauck & Robinson, 2018; Hubbard & Lotts, 2013; Samuelson & Coker, 2014).In addition, in digital humanities pedagogy, there is need for reflection on data or sources beyond “tool-based thinking” which this approach would open up for(Giannetti, 2017). We will share two examples of how we have engaged students with primary sources and discuss the pedagogical challenges and opportunities. Our aim has been to go beyond show and tell and let the students actively work with primary sources. One example, from the Master’s Program in Digital Humanities, involved working with digitised sources using the platform Omeka. In the other, first year students from the Department of Conservation explored primary sources from the Gothenburg Exhibitionheld in 1923. Hopefully, this round table can be a stepping-stone for forming a network where we continue to share our experiences.

The introduction of modern information and communication technologies (ICT) into the classroom has led to a number of challenges and opportunities for instructors across the field of education. Wikipedia, a collaborative encyclopedia, has proven to be one of the most controversial online platforms throughout academia, with many higher education instructors banning its use outright. Despite the prevailing negative attitude, there has been a recent shift in thought among some in the field regarding its utilization as a teaching tool in a number of applications. One popular use is as the centre of a writing project, most commonly the creation of a new article or the improvement of a pre-existing one.This paper outlines a case study conducted at the Latvia University of Life Sciences and Technologies in the autumn semester of 2019, in which first year international veterinarian medicine students wrote Wikipedia articles as part of a semester-long project in an English for academic purposes course in order to improve academic writing skills such as researching, analysing, summarizing, and editing. Analysis of two questionnaires and the students’ work suggest that despite some challenges, a Wikipedia article writing project can serve as an engaging, rewarding, and effective method to teach academic writing skills.
