This paper discusses the various challenges encountered during iterative testing of an insurance company's home page prototypes. The study focuses on the methodology details, including the selection of prototypes and usability evaluation methods and the considerations for practical trade-offs. During Phase 1, six individual think-aloud interviews were conducted to compare three prototypes. Participants were asked to complete tasks on the prototypes. Based on the findings from Phase 1, three prototypes were developed. In Phase 2, an online survey was administered with existing customers to compare these three prototypes. Survey responses indicated that content, layout, and visual appearance were most influential on users' preferences of the designs. At the end of our paper, we compare the implementation and the results of usability evaluation and the prototypes in the two phases and discuss the limitations of the study.

Background Psychosocial rehabilitation is a service that supports recovery from mental illness by providing opportunities for skill development, self-determination, and social interaction. One type of psychosocial rehabilitation is the Clubhouse model. The purpose of the current project was to create, test, and refine a realist theory of psychosocial rehabilitation at Progress Place, an accredited Clubhouse. Method Realist evaluation is a theory driven evaluation that uncovers contexts, mechanisms, and outcomes, in order to develop a theory as to how a program works. The current study involved two phases, encompassing four steps: Phase 1 included (1) initial theory development and (2) initial theory refinement; and Phase 2 included (3) theory testing and (4) refinement. Results The data from this two-phase approach identified three demi-regularities of recovery comprised of specific mechanisms and outcomes: the Restorative demi-regularity, the Reaffirming demi-regularity, and the Re-engaging demi-regularity. The theory derived from these demi-regularities suggests that there are various mechanisms that produce outcomes of recovery from the psychosocial rehabilitation perspective, and as such, it is necessary that programs promote a multifaceted, holistic perspective on recovery. Conclusions The realist evaluation identified that Progress Place promotes recovery for members. Additional research on the Clubhouse model should be conducted to further validate that the model initiates change and promotes recovery outcomes.

The existing body of knowledge reveals that customisable websites may lead to an increase in accessibility and usability for people with disabilities. In this way, the main goal of this research was to investigate how people with dyslexia respond to a customised version of a website in terms of its effectiveness, efficiency, satisfaction and suitability when compared to the default version of the website. The customisation of the investigated website was enabled with the aid of integrated assistive technology that offers people with dyslexia the opportunity to adjust a website themselves in accordance with their individual needs, demands and preferences. They can do this by changing the parameters, such as font size, font type and contrast between the background and text. The answers to the research questions were obtained with complementary research methods and techniques, including formal usability testing, thinking aloud protocol, log analyses, questionnaires and interviews. The empirical results show that participants experienced more issues when interacting with the default website, and they enjoyed more benefits when using the customised website. Too much information on the screen, not enough graphic elements, issues with visual appearance and inappropriately presented information were identified as the most common issues when interacting with the default website. When using the customised website, all participants agreed on a better user experience and, as the majority of them reported, this was due to appropriate contrast and font size. Additionally, the majority of participants also expressed desire to use the individual website adjustments regularly in the future. The conclusions of this investigation are that the individual website adjustments used in this research can not only help to minimise issues, but also eliminate challenges that people with dyslexia have when interacting with a website. Therefore, the primary contributions of this research are the empirical insights of interaction with both the default and customised version of the website for people with dyslexia. Furthermore, this research also has three secondary contributions: (1) detailed presentation and application the general usability evaluation procedure to a specific target group (people with dyslexia); (2) recommendations to adapt the usability evaluation methods for people with dyslexia; and (3) the usage of quantitative measurement instruments for the evaluation of a website’s usability and suitability for people with dyslexia.

The osmotic interaction of mucopolysaccharides and plasma proteins, normally present in the interstitium, has been investigated. It has been found that hyaluronate-plasma protein mixtures may be treated as a two-phase system and that the two phases are in osmotic equilibrium. The osmotic pressures exerted by these mixtures are higher than the algebraic sum of the two components. At concentrations normally present in the interstitium of skin and muscle (0.6% mucopolysaccharides and 2% protein), the osmotic pressure exerted by the mixture is on the order of 10 mmHg, which is in agreement with predictions from earlier computer-simulation studies. The partition of fluid between the gel-like mucopolysaccharide compartment and the free-fluid containing the protein is approximately 50% in the "gel" phase at concentrations found in the interstitium. The volume exclusion effects of the interstitial mucopolysaccharides are significant, both in terms of selection of tracer molecules for interstitial volume measurements and also as an osmotic buffering mechanism which aids in maintaining the partition of fluid between the circulation and the interstitial space.

Evaluating mobile applications and devices is particularly challenging given the variability of users, uses, and environments involved. This chapter introduces usability evaluation methods (UEMs) for mobile applications. Over the past decades various usability evaluation methods have been developed and implemented to improve and assure easy-to-use user interfaces and systems. Since most of the so-called ‘classical’ methods have demonstrated shortcomings when used in the field of mobile applications, they were broadened, varied, and changed to meet the demands of testing usability for mobile applications. This chapter presents a selection of these ‘classical’ methods and introduces some methodological variations for testing usability in the area of mobile devices and applications. It argues for a combination of both field evaluation methods and traditional laboratory testing to cover different phases in the user-centered design and development process.

The crystal structure of a morimotoite garnet, ideally Ca3(Ti4+Fe2+)Si3O12, from the Ice River alkaline complex, British Columbia, Canada was refined by the Rietveld method, space group $Ia\overline 3 d$, and monochromatic synchrotron high-resolution powder X-ray diffraction (HRPXRD) data. Electron-microprobe analysis indicates a homogeneous sample with a formula {Ca2.91Mg0.05Mn2+0.03}Σ3[Ti1.09Fe3+0.46Fe2+0.37Mg0.08]Σ2(Si2.36Fe3+0.51Al0.14)Σ3O12. The HRPXRD data show a two-phase intergrowth. The reduced χ2 and overall R(F2) Rietveld refinement values are 1.572 and 0.0544, respectively. The weight percentage, unit-cell parameter (Å), distances (Å), and site occupancy factors (sofs) for phase-1 are as follows: 76.5(1)%, a = 12.156 98(1) Å, average <Ca–O> = 2.4383, Ti–O = 2.011(1), Si–O = 1.693(1) Å, Ca(sof) = 0.943(2), Ti(sof) = 0.966(2), and Si(sof) = 1.095(3). The corresponding values for phase-2 are 23.5(1)%, a = 12.160 67(2) Å, average <Ca–O> = 2.452, Ti–O = 1.988(3), Si–O = 1.704(3) Å, Ca(sof) = 1.063(7), Ti(sof) = 1.187(7), and Si(sof) = 1.220(8). The two phases cause strain that arises from structural mismatch and gives rise to low optical anisotropy. Because the two phases are structurally quite similar, a refinement using a single-phase model with anisotropic displacement parameters shows no unusual displacement ellipsoid for the O atom that requires a “split O-atom position”, as was done in previous studies.

Abstract A two-phase study was conducted with educators to better understand the current state of the Arkansas beef industry. Educators are defined as individuals who directly work to educate both adults and youth. Ten educators participated in Phase 1 of the study. Nominal group research methods were utilized to identify current strengths, limitations, future opportunities, and future threats to the Arkansas beef industry. The items identified were then compiled for Phase 2 of the study. An online survey was emailed to 100 educators who were randomly selected from a larger list. Survey respondents were asked to rank the importance of items on a Likert-type scale where 1=not important and 5=highly important. Sixty-two surveys were completed of which 40% were adult educators, 34% were K-12 youth educators, 16% were youth educators, and 10% were post-secondary educators. When asked about the current strengths of educational support, participants indicated Educators stay current with knowledge (M = 4.58, SD = 0.64) as the top strength and State funding (M = 3.76, SD = 1.08) as the bottom strength. State, federal, and private investment funding for education, infrastructure, and technology (M = 4.44, SD = 0.73) was ranked with high importance when asked about current limitations whereas Education curriculum in classroom is outdated (M = 3.58, SD = 1.01) was ranked as somewhat important. The top future opportunity was Educating legislators about beef industry (M = 4.72, SD = 0.54) but Get beef cattle producers to increase check-off contribution by one cent (M = 3.26, SD = 1.10) was at the bottom. Lastly, educators ranked Entry costs to the industry (M = 4.51, SD = 0.71) as the most important future threat while Failure to lead or chase issues (M = 3.90, SD = 0.87) as the least important future threat.

Abstract Purpose Magnetic resonance imaging (MRI) is often used to visualize and diagnose soft tissues. Hearing implant (HI) recipients are likely to require at least one MRI scan during their lifetime. However, the MRI scanner can interact with the implant magnet, resulting in complications for the HI recipient. This survey, which was conducted in two phases, aimed to evaluate the safety and performance of MRI scans for individuals with a HI manufactured by MED-EL (MED-EL GmbH, Innsbruck, Austria). Methods A survey was developed and distributed in two phases to HEARRING clinics to obtain information about the use of MRI for recipients of MED-EL devices. Phase 1 focused on how often MRI is used in diagnostic imaging of the head region of the cochlear implant (CI) recipients. Phase 2 collected safety information about MRI scans performed on HI recipients. Results 106 of the 126 MRI scans reported in this survey were performed at a field strength of 1.5 T, on HI recipients who wore the SYNCHRONY CI or SYNCHRONY ABI. The head and spine were the most frequently imaged regions. 123 of the 126 scans were performed without any complications; two HI recipients experienced discomfort/pain. One recipient required reimplantation after an MRI was performed using a scanner that had not been approved for that implant. There was only one case that required surgical removal of the implant to reduce the imaging artefact. Conclusion Individuals with either a SYNCHRONY CI or SYNCHRONY ABI from MED-EL can safely undergo a 1.5 T MRI when it is performed according to the manufacturer’s safety policies and procedures.

Abstract We determined how parasitized sheep prioritize selection of crude protein, energy and a medicinal plant secondary compound (quebracho tannins-QT). Foraging preferences were tested in 40 lambs before experiencing a parasitic infection (Phase 1), during an infection (Phase 2; 10,000 L3 Haemonchus contortus per lamb) and after chemotherapy (Phase 3). Lambs were assigned to four groups (10 lambs/group) such that animals in Group 1 (Control) could choose between rations of high energy (HE) or high protein (HP) density. The other groups received the same choice, but QT were added (4%) to HE (Group 2), to HP (Group 3) or to both HE and HP (Group 4). Intake and preference indexes were analyzed as a split-plot design with lambs nested within group and day as the repeated measure. All groups increased their preference for HE when parasitized relative to Phase 1 (0.66 and 0.44 ± 0.042, respectively; P &lt; 0.05). As a result, lambs increased their intake of digestible energy during Phase 2 (0.126 ± 0.007 Mcal/kg BW) relative to Phase 1 (0.106 ± 0.007 Mcal/kg BW; P &lt; 0.05). These patterns remained during Phase 3. Only lambs receiving QT in the HE increased their intake of condensed tannins from Phase 1 to Phase 2 (P &lt; 0.05). Fecal egg counts (FEC) and blood parameters revealed a parasitic infection (P &lt; 0.05) in Phase 2 that subsided in Phase 3, although no differences were detected among groups (P &gt; 0.05). The importance of protein nutrition on parasitized animals has been highlighted before, but these results suggest that parasitized lambs prioritized the ingestion of energy-dense over protein-dense foods or medicinal condensed tannins. Nevertheless, intake of tannins increased when these compounds were present in the energy-dense food, suggesting that selection of condensed tannins was influenced by the nutritional composition of the foods during testing.

Purpose: This two-phase project employed qualitative framing analyses to explore how fibromyalgia has been framed in some of the top sources of U.S. health information and how these sources address treatments related to fibromyalgia. Methods: Phase 1 of the project examined 95 stories and articles published between January 1, 2007, and October 15, 2010, in eight elite U.S. newspapers and five mosttrafficked health websites to determine the dominant framing of fibromyalgia in each source. Phase 2 analyzed 146 stories and articles published between January 1, 2007, and May 15, 2013, in 15 topcirculation U.S. daily print and online newspapers and five popular health websites. Phase 2 was conducted to examine changes in the dominant framing of fibromyalgia since Phase 1, and identify new frames in the ongoing debate about whether fibromyalgia is a medical or mental condition. Results: Project findings suggest a lessening in the debate insofar as the overall media representation shifted from a depiction of fibromyalgia as a mental to a medical condition. Moreover, changes found between the two phases in the identification of the frames demonstrate the evolving public discussion surrounding fibromyalgia amid FDA approval of drugs specifically for the treatment of the condition. Conclusion: Thus, the marketing of fibromyalgia-specific drugs may be a factor contributing to the legitimization of the controversial condition.
