The e-interview in qualitative research

In this chapter the authors consider using email as a method for carrying out in-depth, qualitative research interviews. Prompted by an experience of conducting e-interviews, they set out some of their key characteristics, embedding their discussion in the methodological and conceptual literature on qualitative interview and on-line research. The authors then offer a methodological consideration of e-interviewing, focusing on three broad areas: the practical, the interpersonal, and the ethical, highlighting the ways in which e-interviewing transforms aspects of each. They end by offering a view of the future of e-interviewing in the broader landscape of on-line qualitative research methods in general and interviewing in particular

Wireless handheld device and LAN security issues: a case study

The application of WLAN (Wireless Local Area Network) technology in the healthcare industry has gained increasing attention in recent years. It provides effective and efficient sharing of health information among healthcare professionals in timely and effective treatment of patients (Collaborative Health Informatics Centre, 2000, Whetton, 2005a). However, there is still a concern among healthcare professionals whether health information is shared safely with WLAN technology. The primary aim of this study is to explore factors influencing healthcare professionals' adoption of WLAN security technology. This study was conducted in regional health settings in Queensland, Australia with a mixed research methodology. A focus group discussion and a questionnaire survey were used in the mixed research methodology. Four factors were extracted from the study. Learning support, user technology awareness, readiness of existing system and social influence are four important factors in healthcare professionals' adoption of WLAN security technology in this study. The findings suggest that healthcare professionals prefer to be more informed and prepared on knowledge of WLAN security technology before they decide to adopt it in their work environment. Healthcare professionals are concerned with their interaction with WLAN security technology. Therefore, their awareness of what the technology can do and cannot do for them and the support they could get in learning to use the technology play a crucial role. The healthcare professionals are also concerned with how readily their existing system could support WLAN security technology and how people important to them would influence their decision in adopting WLAN security technology. Future research should extend the study in three areas. Firstly, future study should examine factors in this study with more regional areas of Australia. Secondly, future research should also examine the relationship between the factors and the demographic variables. Finally, there is also the possibility of examining the adoption factors with other security technology in healthcare such as the pairing of WLAN technology and biometric security

Dark energy survey year 3 results: Cosmological constraints from the analysis of cosmic shear in harmonic space

We present cosmological constraints from the analysis of angular power spectra of cosmic shear maps based on data from the first three years of observations by the Dark Energy Survey (DES Y3). Our measurements are based on the pseudo-Cℓ method and complement the analysis of the two-point correlation functions in real space, as the two estimators are known to compress and select Gaussian information in different ways, due to scale cuts. They may also be differently affected by systematic effects and theoretical uncertainties, making this analysis an important cross-check. Using the same fiducial Lambda cold dark matter model as in the DES Y3 real-space analysis, we find S8 ≡σ8 √Ωm/0.3 = 0.793-0.025+0.038 , which further improves to S8 = 0.784±0.026 when including shear ratios. This result is within expected statistical fluctuations from the real-space constraint, and in agreement with DES Y3 analyses of non-Gaussian statistics, but favours a slightly higher value of S8 , which reduces the tension with the Planck 2018 constraints from 2.3σ in the real space analysis to 1.5σ here. We explore less conservative intrinsic alignments models than the one adopted in our fiducial analysis, finding no clear preference for a more complex model. We also include small scales, using an increased Fourier mode cut-off up to kmax = 5 h Mpc-1 , which allows to constrain baryonic feedback while leaving cosmological constraints essentially unchanged. Finally, we present an approximate reconstruction of the linear matter power spectrum at present time, found to be about 20 per cent lower than predicted by Planck 2018, as reflected by the lo wer S8 value
