Fear of cyber-identity theft and related fraudulent activity
Identity theft and related fraudulent activities affect approximately one in twenty-five adults each year across western societies. The Internet provides a new avenue for obtaining identity tokens and identifying information and increases the scale on which identity theft can be perpetrated. Recent research has suggested that fear of these types of crimes now matches or exceeds the fear of traditional place-based crimes, and has the potential to curtail online activities and hinder the further development of e-commerce applications. In this article, we conduct exploratory research identifying predictors of fear of cyber-identity theft and related fraudulent activities, based on the analysis of items included in the Australian Survey of Social Attitudes (2007). Fear was predicted by a generalized fear of crime component and a specific Internet exposure component. Traditional predictors of fear of crime were insignificant or weak predictors, highlighting the need for further research
Interprofessional education for first year psychology students: career plans, perceived relevance and attitudes
Undergraduate psychology students have been largely excluded from interprofessional education (IPE) initiatives. In contrast to many health professions, undergraduate psychology students do not engage in work placements as part of their degree, and many enter careers outside the health care context. However, the collaborative skills gained through an IPE experience may well be beneficial to students who work in this wider context. This research examines whether undergraduate psychology students’ views of IPE vary according to their planned career directions, and if so, whether the perceived relevance of IPE mediates the relationships. A sample of 188 Australian university undergraduate psychology students completed an online questionnaire following completion of a first-year IPE health sciences program. Path analysis indicated that psychology students’ attitudes towards IPE are associated with both professional identification and practitioner orientation, fully mediated through the perceived relevance of IPE to future career and study plans. Stronger professional identification and practitioner orientation were associated with greater perceived relevance and more positive and less negative attitudes towards IPE. Placing a stronger emphasis on the generalizability of IP skills taught may increase students’ awareness of the relevance outside of the health context, reducing disengagement of students planning alternative careers
Students' Experiences of Undergraduate Dissertation Supervision
Increasingly, students completing undergraduate dissertations in Australia are expected by their supervisors to produce publishable research. Despite this, limited resources are available for supervisors of undergraduate dissertation students on how best to supervise students toward this aim. Building on our previous research on the perspectives of supervisors and dissertation coordinators of what constitutes good undergraduate dissertation supervision, we present here the findings on student perspectives of good supervision. Twenty-five students (seventeen students who were currently completing an undergraduate dissertation and eight who had recently completed an undergraduate dissertation) were interviewed about their experiences in being supervised. A critical incident methodology was used to invite students to reflect on times when supervision had gone well, and times when it had not. Interviews were recorded and transcribed and analyzed using thematic analysis. Key themes to emerge were that students viewed “good” supervisors as those that were supportive and empowering, directed learning, and whose style and interests aligned with those of the students. Challenges in supervision related to lack of clarity and inconsistencies, perceived power imbalances between students and supervisors, and perceived inequities in the amount of supervision provided across students. Whilst the publication of undergraduate research is a worthy aim, the pressure to publish for some students resulted in feelings of inadequacy and perceptions of supervisors losing interest when findings were not deemed publishable
Constraining mass ratio and extinction in the FU Orionis binary system with infrared integral field spectroscopy
We report low resolution near infrared spectroscopic observations of the
eruptive star FU Orionis using the Integral Field Spectrograph Project 1640
installed at the Palomar Hale telescope. This work focuses on elucidating the
nature of the faint source, located 0.5" south of FU Ori, and identified in
2003 as FU Ori S. We first use our observations in conjunction with published
data to demonstrate that the two stars are indeed physically associated and
form a true binary pair. We then proceed to extract J and H band
spectro-photometry using the damped LOCI algorithm, a reduction method tailored
for high contrast science with IFS. This is the first communication reporting
the high accuracy of this technique, pioneered by the Project 1640 team, on a
faint astronomical source. We use our low resolution near infrared spectrum in
conjunction with 10.2 micron interferometric data to constrain the infrared
excess of FU Ori S. We then focus on estimating the bulk physical properties of
FU Ori S. Our models lead to estimates of an object heavily reddened, A_V
=8-12, with an effective temperature of ~ 4000-6500 K . Finally we put these
results in the context of the FU Ori N-S system and argue that our analysis
provides evidence that FU Ori S might be the more massive component of this
binary syste

Health related quality of life in sickle cell patients: The PiSCES project
BACKGROUND: Sickle cell disease (SCD) is a chronic disease associated with high degrees of morbidity and increased mortality. Health-related quality of life (HRQOL) among adults with sickle cell disease has not been widely reported. METHODS: We administered the Medical Outcomes Study 36-item Short-Form to 308 patients in the Pain in Sickle Cell Epidemiology Study (PiSCES) to assess HRQOL. Scales included physical function, physical and emotional role function, bodily pain, vitality, social function, mental health, and general health. We compared scores with national norms using t-tests, and with three chronic disease cohorts: asthma, cystic fibrosis and hemodialysis patients using analysis of variance and Dunnett's test for comparison with a control. We also assessed whether SCD specific variables (genotype, pain, crisis and utilization) were independently predictive of SF-36 subscales, controlling for socio-demographic variables using regression. RESULTS: Patients with SCD scored significantly worse than national norms on all subscales except mental health. Patients with SCD had lower HRQOL than cystic fibrosis patients except for mental health. Scores were similar for physical function, role function and mental health as compared to asthma patients, but worse for bodily pain, vitality, social function and general health subscales. Compared to dialysis patients, sickle cell disease patients scored similarly on physical role and emotional role function, social functioning and mental health, worse on bodily pain, general health and vitality and better on physical functioning. Surprisingly, genotype did not influence HRQOL except for vitality. However, scores significantly decreased as pain levels increased. CONCLUSION: SCD patients experience health related quality of life worse than the general population, and in general, their scores were most similar to patients undergoing hemodialysis. Practitioners should regard their HRQOL as severely compromised. Interventions in SCD should consider improvements in health related quality of life as important outcomes
Attitudes toward mixed methods research in psychology: the best of both worlds?
In psychology, there has been a growing interest in mixed methods approaches, however, only a minority of published research explicitly use this methodology. This study aimed to explore the full range of attitudes toward mixed methods research in psychology held by students and academics, using the model of attitudes by Eagly and Chaiken as a framework. Fourteen psychology students and seven academics (48% male and 52% female with ages ranging from 19- to 64-years old) were interviewed about their attitudes toward mixed methods research. Interviews were transcribed and analyzed using thematic analysis. Findings indicate that while participants were generally open to the methodology, misunderstandings were common, most felt they lacked the skills and experience necessary to conduct this research and many were sceptical of mixed methods researchers’ motivations and practices. Identifying attitudes toward mixed methods research has the potential to dispel myths, promote attitudinal change, and increase both the use and teaching of this approach in psychology
Exploring ethical issues associated with using online surveys in educational research
Online surveys are increasingly used in educational research, yet little attention has focused on ethical issues associated with their use in educational settings. Here, we draw on the broader literature to discuss 5 key ethical issues in the context of educational survey research: dual teacher/researcher roles; informed consent; use of incentives; privacy, anonymity, and confidentiality; and data quality. We illustrate methods of addressing these issues with our experiences conducing online surveys in educational contexts. Moving beyond the procedural ethics approach commonly adopted in quantitative educational research, we recommend adopting a situated/process ethics approach to identify and respond to ethical issues that may arise during the conduct, analysis, and reporting of online survey research. The benefits of online surveying in comparison to traditional survey methods are highlighted, including the potential for online surveys to provide ethically defensible methods of conducting research that would not be feasible in offline education research settings
Gas phase characterization of the noncovalent quaternary structure of Cholera toxin and the Cholera toxin B subunit pentamer
Cholera toxin (CTx) is an AB5 cytotonic protein that has medical relevance in cholera and as a novel mucosal adjuvant. Here, we report an analysis of the noncovalent homopentameric complex of CTx B chain (CTx B5) using electrospray ionization triple quadrupole mass spectrometry and tandem mass spectrometry and the analysis of the noncovalent hexameric holotoxin usingelectrospray ionization time-of-flight mass spectrometry over a range of pH values that correlate with those encountered by this toxin after cellular uptake. We show that noncovalent interactions within the toxin assemblies were maintained under both acidic and neutral conditions in the gas phase. However, unlike the related Escherichia coli Shiga-like toxin B5 pentamer (SLTx B), the CTx B5 pentamer was stable at low pH, indicating that additional interactions must be present within the latter. Structural comparison of the CTx B monomer interface reveals an additional α-helix that is absent in the SLTx B monomer. In silico energy calculations support interactions between this helix and the adjacent monomer. These data provide insight into the apparent stabilization of CTx B relative to SLTx B
