To design interventions for teaching laypeople how to respond in hemorrhage situations, it is necessary to understand factors that influence their perception of blood loss. Although lab-based research offers more experimental control, it limits access to certain kinds of participants. Therefore, the purpose of this study was to compare results from an online administration of a web-based application (SABLE) to data collected using the same application in a lab. Participants viewed 78 5-second video clips of simulated bleeding injuries with a male or female victim and different volumes of blood loss. They estimated the volume of blood loss after each video. The results replicated the general findings from prior research and revealed no significant differences in estimations or estimation accuracy between the online and lab-based administration of SABLE. Results are discussed in terms of applicability to research practice.

Key Aspects

AbstractThe present article addresses ethical issues and tensions that have arisen in the context of language-focused research on web-based mourning. It renders explicit the process of ethical decision-making in research practice, illustrating key aspects of a process approach to research ethics, which calls for reflection on ethical issues as an integral and dynamic part of the project (Markham and Buchanan 2015. Ethical considerations in digital research contexts. In James Wright (ed.) Encyclopedia for Social & Behavioral Sciences. Elsevier Press. 606–613; Page et al. 2014. Researching Language and Social Media: A student guide. Oxon: Routledge). In addition, the article draws attention to some vexing ethical tensions raised in research practice and, in particular, to the uses of the terms private and public in research ethics frameworks and in discipline-specific discussions. Based on Gal’s (2005. Language ideologies compared: metaphors of public/private. Journal of Linguistic Anthropology 15 (1): 23–38) semiotic investigation of the private/public opposition, it is shown how the two categories are used as a language ideology of differentiation that discursively contrasts spaces and forms of emotional communication. It is argued that such metaphorical uses of the terms limit their currency in internet research on language, mourning, and death online, which tends to feature the construction and staging of a public self in semi-public contexts. The article concludes with a discussion of the implications of the issues raised in language-focused research on web-based mourning for research ethics as method (Markham 2004. Method as ethic, ethic as method. Journal of Information Ethics 15 (2): 37–55) and calls for the critical study of the key concepts that underlie research ethics stances as a key step in rethinking – or ‘undoing’ – ethics (Whiteman 2012. Undoing Ethics: Rethinking Practice in Online Research. London: Springer).

Effects Of Media

This study investigated the disempowering effect of exposure to media violence against women on female students. An initial study involving 284 female students described the development and evaluation of two forms of a scale measuring disempowerment. The second study investigated the effect of media violence using a Solomon Four-Group experimental design. Fifty-seven female students were divided into four groups that were shown video clips depicting scenes of violence directed either toward female or male victims. Half the groups completed the first form of the disempowerment scale prior to the viewing. All groups completed the second form of the scale after the viewing. Analysis confirmed that completion of the pretest scale did not differentially affect the participants viewing the female-victim clips. The results of the main analysis revealed that exposure to media aggression against women heightens feelings of disempowerment in female viewers.

A Web-based training course with embedded video clips for reducing central line-associated bloodstream infections (CLABSIs) was evaluated and shown to improve clinician knowledge and retention of knowledge over time. To our knowledge, this is the first study to evaluate Web-based CLABSI training as a stand-alone intervention.

Web Based System

An interactive web-based system was designed to facilitate communication between nonspecialist speech pathologists who provide therapy for individuals with speech disorders associated with cleft palate or craniofacial anomalies and specialist speech pathologists who provide physiologically based assessments of speech production. The web site includes instructional presentations, streaming video clips of endoscopic examinations, and exchange of information about the nature of therapy as recommended by the specialist and as provided by the nonspecialist. The approach demonstrates use of web-based computer facilities to improve the quality of communication among professionals with the goal of improving the outcomes of speech therapy. Information from the site can also be used in academic training programs as a teaching tool in courses on cleft palate speech.

Abstract Portion size images are advantageous in dietary assessment. The aim of the present study was to develop and validate new culturally specific image-series for portion size estimation to be used in a new Norwegian version of a British web-based dietary assessment tool (myfood24). Twenty-three image-series of different foods, each containing seven portion size images, were created and validated in a group of adults (n 41, 58 % female) aged 19–44 (median 23), out of which 63 % had higher (tertiary) education. The participants compared 46 portions of pre-weighed foods to the portion size images (1886 comparisons in total). Portion size estimations were either classified as correct, adjacent or misclassified. The weight discrepancy in percentage between the chosen and the correct portion size image was also calculated. Mann–Whitney U tests were used to explore if portion size estimation accuracy differed across sample characteristics, or if it depended on how the foods were presented. For thirty-eight of the forty-six presented food items, the participants selected the correct or adjacent portion size image 98 % on average. The remaining eight food items were on average misclassified by 27 % of the participants. Overall, a mean weight discrepancy of 2⋅5 % was observed between the chosen and the correct portion size images. Females estimated portion size more accurately than males (P = 0⋅019). No other significant differences in estimation accuracy were observed. In conclusion, the new image-series performed satisfactorily, except for the image-series depicting bread, caviar spread and marzipan cake, which will be altered. The present study demonstrates the importance of validating portion size estimation tools.

This paper describes the development, implementation and evaluation of a multimedia case study on dietetic case management of diabetes. A multimedia web-based program was developed to use the interactive capacity of the web-based environment to enable student dietitians to develop the skills of clinical reasoning and to trigger their learning about the nutritional management of diabetes. A case study of a person with diabetes was developed using a simulated medical history, video clips and sound clips. The students were asked to manage the patient online by responding to the patient's questions, attending a team meeting and outpatient clinic, attending to food service tasks and responding to visual cues. Tutors were able to access the student's responses to submissions online. Evaluation of the program was by questionnaire, which gathered quantitative and qualitative data on the student's perceptions of their experiences in using the web-based case. The students rated the content and the interactive parts of the case highly but experienced technical difficulties and found the case took too much time to complete.
