UI-Design driven model-based testing
Testing interactive systems is notoriously difficult. Not only do we need to ensure that the functionality of the developed system is correct with respect to the requirements and specifications, we also need to ensure that the user interface to the system is correct (enables a user to access the functionality correctly) and is usable. These different requirements of interactive system testing are not easily combined within a single testing strategy. We investigate the use of models of interactive systems, which have been derived from design artefacts, as the basis for generating tests for an implemented system. We give a model-based method for testing interactive systems which has low overhead in terms of the models required and which enables testing of UI and system functionality from the perspective of user interaction
Development of a decreased calorie cake mix containing ascorbyl palmitate and fructose
An experimental yellow cake mix was formulated which was used to determine the effects of ascorbyl palmitate (0.00, 0.33, 0.67, and 1.00% FWB) as a shortening-sparing agent and fructose as a replacement for sucrose at 0, 25, 50, and 75% of the total sugar on the quality of the baked cake. The FWB was the original flour weight in the cake mix prior to cellulose substitution. All possible combinations of ascorbyl palmitate (AP) levels and fructose levels were tested, and each combina-tion was a treatment. The resulting 16 treatments and a control yellow cake were replicated twice. The cake mix contained 25% cellulose substituted for flour, 66.67% (FWB) total sugar, 7% (FWB) double action baking powder, 5% (FWB) shortening, 1% (FWB) distilled monoglycerides, 0.5% (FWB) lecithin, and 0.06% (FWB) beta-carotene. All cakes were analyzed for volume, weight, height, diameter, crumb color, hardness at 0, 1, 3, and 5 days storage, moisture, and lipid content and subjectively evaluated for softness, tenderness, moistness, flavor, cell size uniformity, cell size and wall thickness, grain, and color. In addition, cake batter specific volume and viscosity, AP recovery from the experi-mental cakes, and chemical composition of one rep of cakes were deter-mined. Substitution of fructose for sucrose resulted in decreased cake tenderness and volume and increased cake weight. Cakes containing 66.67% (FWB) sugar were judged between slightly sweet and moderately sweet except for cakes containing 50% fructose in the total sugar which were judged just above moderately sweet. Addition of AP generally produced a lighter cake with less moisture, a silkier grain, and more uniform cell size. AP also increased cake tenderness and decreased cake hardness. Addition of AP at or above 0.67% (FWB) in cake batters containing fructose also resulted in more panelists scoring cake texture as gummy. Fructose level at 75% of the total sugar resulted in more panelists detecting a gummy texture and an off-flavor in the cake. AP recovery ranged from approximately 15% in cakes made from batter containing 0.33% (FWB) AP to approximately 40% in cakes made from batters containing 1% AP (FWB). The experimental cake was much heavier and softer (determined by shear), had larger, less uniform cells in the crumb, and a less silky grain than did the control. Compared with the control cake, the experimental cake had more moisture (41.1 versus 26.9%) and less fat (6.1 versus 14.1% on a dry matter basis). The experimental cake with the sweetest flavor and best quality was made from batter which contained 50% fructose in the total sugar and 0.33% AP (FWB). The experimental cake had 229 calories/100 g com-pared to 344 calories/100 g for the control cakes which represented a 33.4% calorie reduction. Cost estimates showed that the cost of the experimental cake at the time the study was performed was 1.5 times as much as the cost of the control cake
Attitudes towards deprescribing and the influence of health literacy among older Australians
Aim
This study aimed to explore attitudes, beliefs and experiences regarding polypharmacy and discontinuing medications, or deprescribing, among community living older adults aged ā„65 years, using ā„5 medications. It also aimed to investigate if health literacy capabilities influenced attitudes and beliefs towards deprescribing. Background
Polypharmacy use is common among Australian older adults. However, little is known about their attitudes towards polypharmacy use or towards stopping medications. Previous studies indicate that health literacy levels tend to be lower in older adults, resulting in poor knowledge about medications. Methods
A self-administered survey was conducted using two previously validated tools; the Patientsā Attitude Towards Deprescribing (PATD) tool to measure attitudes towards polypharmacy use and deprescribing and the All Aspects of Health Literacy Scale (AAHLS) to measure functional, communicative and critical health literacy. Descriptive statistical analysis was conducted. Findings
The 137 responses showed that 80% thought all their medications were necessary and were comfortable with the number taken. Wanting to reduce the number of medications taken was associated with concerns about the amount taken (P\u3c0.001), experiencing side effects (P\u3c0.001), or believing that one or more medications were no longer needed (P\u3c0.000). Those who were using ten or more medications were more likely to want to reduce the number taken (P=0.019). Most (88%) respondents would be willing to stop medication/s in the context of receiving this advice from their doctor. Willingness to consider stopping correlated with higher scores on the critical health literacy subscale (P\u3c0.021) and overall AAHLS score (P\u3c0.009). Those with higher scores on the overall AAHLS measure were more likely to report that they understood why their medications were prescribed (P\u3c0.000) and were more likely to participate in decision-making (P=0.027). Opportunities to proactively consider deprescribing may be missed, as one third of the respondents could not recall a recent review of their medications
Social Media as a Supplement to Face-to-Face Education: The Perspectives of Expanded Food and Nutrition Education Program Paraprofessionals and Graduates
Using social media is an inexpensive, innovative approach to supplementing direct education provided by the Expanded Food and Nutrition Education Program (EFNEP). Focus group research was conducted with EFNEP paraprofessionals (n = 33) and participants (n = 39) to inform the development of a social media presence for the program. Although recommendations by EFNEP\u27s social media committee focus on providing online articles, focus group results suggest that content should be presented as colorful pictures and videos, portraying recipes and nutrition tips. Also, the study highlights the importance of using engaging, colorful visuals when using social media as a form of indirect education

Medication Management for People Living with Dementia: Development and Evaluation of a Multilingual Information Resource for Family Caregivers of People Living with Dementia
The aim of this chapter is to describe the development and evaluation of an online multilingual information resource focused on medication management, targeting people living with dementia and their family caregivers. Maintaining effective medication management is important to allow ongoing quality of life within the community setting and avoiding medication-related preventable hospitalisations for the person living with dementia. Family caregivers are likely to assume the role of medication management on behalf of the person in their care as dementia progresses. Little training or information is available to family caregivers to assist them with this role. A pilot online information resource was developed and evaluated. Responding to the evaluation, this resource was improved, and a more extensive evaluation process was undertaken. The development and evaluation process are outlined with a view to guiding the development of similar resources, especially those targeting linguistically diverse family caregivers and those with dementia. This is especially important given that many older adults will migrate during their lifetime, often to a country where they are not familiar with the language or health services. Extra support is needed to assist older immigrants who are themselves at risk or are caring for someone with dementia
Effect of In Situ Thermal Annealing on Structural, Optical, and Electrical Properties of CdS/CdTe Thin Film Solar Cells Fabricated by Pulsed Laser Deposition
An in situ thermal annealing process (iTAP) has been introduced before the common ex situ cadmium chloride (CdCl2) annealing to improve crystal quality and morphology of the CdTe thin films after pulsed laser deposition of CdS/CdTe heterostructures. A strong correlation between the two annealing processes was observed, leading to a profound effect on the performance of CdS/CdTe thin film solar cells. Atomic force microscopy and Raman spectroscopy show that the iTAP in the optimal processing window produces considerable CdTe grain growth and improves the CdTe crystallinity, which results in significantly improved optoelectronic properties and quantum efficiency of the CdS/CdTe solar cells. A power conversion efficiency of up to 7.0% has been obtained on thin film CdS/CdTe solar cells of absorber thickness as small as 0.75āĪ¼m processed with the optimal iTAP at 450Ā°C for 10ā20āmin. This result illustrates the importance of controlling microstructures of CdTe thin films and iTAP provides a viable approach to achieve such a control
