A tool for Swarm satellite data analysis and anomaly detection.

In this work we introduce a system pipeline for the analysis of earth's electromagnetic field that is used to analyse precursors to earthquakes. Data gathered by the Swarm satellites are used to present the utility of our system. Our objective is to provide a streamlined method to analyze electromagnetic data over a region and investigate the relationship of precursory signals to seismic events. The process follows three distinct stages: data extraction, data pre-processing and anomaly detection. The first stage consists of the region selection and data extraction. The second stage consists of four different pre-processing methods that address the data sparsity problem and the cause of artificial anomalies. The last stage is the Anomaly Detection (AD) of the Swarm satellite data, over the investigated region. The different methods that are implemented are known to perform well in the field of AD. Following the presentation of our system, a case study is described where the seismic event of 6.2 Mw is in Ludian, China and occurred on 3rd August 2014. The event is used to present the usefulness of our approach and pinpoint some critical problems regarding satellite data that were identified.

Developing professional identity in nursing academics: the role of communities of practice.

This paper analyses the current standing of nursing within the wider United Kingdom (UK) higher education (HE) environment and considers the development of academic identity within the sector, introducing a technology mediated approach to professional learning and development. A community of practice (CoP) is a way of learning based on collaboration among peers. Individuals come together virtually or physically, with a common purpose, defined by knowledge rather than task [Wenger, E., 1998. Communities of Practice: Learning, Meaning and Identity, sixth ed. Cambridge University Press, Cambridge]. In 2008, a small team of academics at Glasgow Caledonian University, School of Nursing, Midwifery and Community Health created and implemented iCoP, a project undertaken to pilot an international CoP, where novices and expert academics collaborated to debate and discuss the complex transition from clinician to academic. Although not intended as a conventional research project, the developmental journey and emerging online discussion provide an insight into the collective thoughts and opinions of a multi-national group of novice academics. The article also highlights the key challenges, problems and limitations of working in an international online arena with professionals who traditionally work and thrive in a face to face, real time environment.
