- ObjectivesPodcasts are increasingly being used for medical education. A deeper understanding of usage patterns would inform both producers and researchers of medical podcasts. We aimed to determine how and why podcasts are used by emergency medicine and critical care clinicians.MethodsAn international interprofessional sample (medical students, residents, physicians, nurses, physician assistants, and paramedics) was recruited through direct contact and a multimodal social media (Twitter and Facebook) campaign. Each participant completed a survey outlining how and why they utilize medical podcasts. Recruitment materials included an infographic and study website.Results390 participants from 33 countries and 4 professions (medicine, nursing, paramedicine, physician assistant) completed the survey. Participants most frequently listened to medical podcasts to review new literature (75.8%), learn core material (75.1%), and refresh memory (71.8%). The majority (62.6%) were aware of the ability to listen at increased speeds, but most (76.9%) listened at 1.0 x (normal) speed. All but 25 (6.4%) participants concurrently performed other tasks while listening. Driving (72.3%), exercising (39.7%), and completing chores (39.2%) were the most common. A minority of participants used active learning techniques such as pausing, rewinding, and replaying segments of the podcast. Very few listened to podcasts multiple times.ConclusionsAn international cohort of emergency clinicians use medical podcasts predominantly for learning. Their listening habits (rarely employing active learning strategies and frequently performing concurrent tasks) may not support this goal. Further exploration of the impact of these activities on learning from podcasts is warranted.

Modelling of single-crystal diamond Schottky diodes for high-voltage applications
- 2006

In: Diamond and related materials. - : Elsevier BV. - 0925-9635 .- 1879-0062. ; 15, s. 317-323

Journal article (peer-reviewed)abstract
- The modelling of Schottky m-i-p(+) (SMIP) diodes fabricated on chemical vapour deposited (CVD) single crystal (SC) diamond intrinsic layers grown on highly boron doped CVD diamond Substrates is reported. Variations in intrinsic layer thickness, Schottky metal type and operating temperature have been included in the analysis. Numerical models that take into account the activation of dopants, concentration and temperature dependant mobility and avalanche coefficients have been derived to successfully simulate experimental diamond devices.

Numerical Parameterization of Chemical-Vapor-Deposited (CVD) Single-Crystal Diamond for Device Simulation and Analysis
- 2008

In: IEEE Transactions on Electron Devices. - 0018-9383 .- 1557-9646. ; 55:10, s. 2744-2756

Journal article (peer-reviewed)abstract
- High-quality electronic-grade intrinsic chemical-vapor-deposited (CVD) single-crystal diamond layers having exceptionally high carrier mobilities have been reported by Isberg et al. This makes the realization of novel electronic devices in diamond, particularly for high-voltage and high-temperature applications, a viable proposition. As such, material models which can capture the particular features of diamond as a semiconductor are required to analyze, optimize, and quantitatively design new devices. For example, the incomplete ionization of boron in diamond and the transition to metallic conduction in heavily boron-doped layers require accurate carrier freeze-out models to be included in the simulation of diamond devices. Models describing these phenomena are proposed in this paper and include numerical approximation of intrinsic diamond which is necessary to formulate doping- and temperature-dependent mobility models. They enable a concise numerical description of single-crystal diamond which agrees with data obtained from material characterization. The models are verified by application to new Schottky m-i-p(+) diode structures in diamond. Simulated forward characteristics show excellent correlation with experimental measurements. In spite of the lack of impact ionization data for single-crystal diamond, approximation of avalanche coefficient parameters from other wide-bandgap semiconductors has also enabled the reverse blocking characteristics of diamond diodes to be simulated. Acceptable agreement with breakdown voltage from experimental devices made with presently available single-crystal CVD diamond is obtained.

Towards an Inclusive Disaster Education : The State of Online Disaster Education from the Learner’s Perspective

Journal article (peer-reviewed)abstract
- Disaster Risk Reduction (DRR) education endorses educational initiatives that advocate for reducing existing disaster risks. The COVID-19 pandemic challenged the social order around the world, including the education sector. The rise of the pandemic paved the way to significantly convert the education sector towards online/distant learning via digital platforms. Online distance learning was a challenging emergency shift for many who had to change their teaching and learning strategies. This study is an investigation of the significant challenges associated with online learning in DRR education. The objectives of the study were to consider the online learning strategies used in formal DRR education at the tertiary level and to identify the associated challenges faced by the learners. This study presents the findings of an online survey conducted as part of a research collaboration titled INCLUsive Disaster Education (INCLUDE). INCLUDE is a collaborative research project co-funded by the EU Erasmus+ program aimed to reimagine online distance learning education. The survey was conducted in the country contexts of the research partners, which include Lithuania, Japan, Sweden, and the UK, with DRR learners who are engaged in online learning. The findings suggest that Learning Management Systems, synchronous learning, and flipped classrooms are the dominant learning strategies that engage learners. The findings further suggest that challenges in online DRR education lie in inadequate ICT infrastructure and digital literacy, health-related disturbances, and professional and personal commitments that lead into learning discontinuity. Hence, the study concludes that in order to enhance the inclusivity of online DRR education, the overall social and vulnerability contexts of the learners should be considered.

A built environment perspective on post-disaster and conflict- induced displacement.
- 2022
-
Reports (other academic/artistic)abstract
- Displacement is one of the most pressing challenges faced by the society today. REGARD (REbuildinGAfteR Displacement) is a collaborative research project co-funded by EU Erasmus+ programme, which set out to investigate the role of built environment in the context of displacement. The REGARD project launched in September 2018 with an aim to develop competencies in rebuilding communities following a disaster and conflict-induced mass displacements from the perspective of the built environment. The project consortium consists of five international universities in four different countries: University of Huddersfield, UK (project lead); Lund University, Sweden; University of Central Lancashire, UK; Tallinn University of Technology, Estonia; University of Colombo, Sri Lanka.

Does hydrogen change the fullerenelike structure in CNx thin films?
- 2009
-
In: JOURNAL OF VACUUM SCIENCE and TECHNOLOGY A. - : American Vacuum Society. - 0734-2101. ; 27:5, s. 1227-1230
-
Journal article (peer-reviewed)abstract
- The authors have reported the structure of the nanoclusters in carbon nitride thin films before [D. Roy , Phys. Rev. B 70, 035406 (2004)]. In this work, effects of the addition of hydrogen in the deposition gas mixture on the structures of carbon nitride thin films prepared by magnetron sputtering were investigated using Raman spectroscopy. Raman measurements showed that the structures of carbon nanoclusters remained unaffected by the addition of hydrogen in the carbon nitride films. On the other hand, the structures of amorphous thin films were affected by the addition of hydrogen in the deposition gas mixture. These are explained in terms of changes in the ratios of the D-peak to the G-peak intensities and shifts in the G-peak centers.
