Case study:exploring childrenâs password knowledge and practices
Children use technology from a very young age, and often have to authenticate themselves. Yet very little attention has been paid to designing authentication specifically for this particular target group. The usual practice is to deploy the ubiquitous password, and this might well be a suboptimal choice. Designing authentication for children requires acknowledgement of child-specific developmental challenges related to literacy, cognitive abilities and differing developmental stages. Understanding the current state of play is essential, to deliver insights that can inform the development of child-centred authentication mechanisms and processes. We carried out a systematic literature review of all research related to children and authentication since 2000. A distinct research gap emerged from the analysis. Thus, we designed and administered a survey to school children in the United States (US), so as to gain insights into their current password usage and behaviors. This paper reports preliminary results from a case study of 189 children (part of a much larger research effort). The findings highlight age-related differences in childrenâs password understanding and practices. We also discovered that children confuse concepts of safety and security. We conclude by suggesting directions for future research. This paper reports on work in progress.<br/
âPasswords protect my stuffâ - a study of childrenâs password practices
Children use technology from a very young age and often have to authenticate. The goal of this study is to explore childrenâs practices, perceptions, and knowledge regarding passwords. Given the limited work to date and that the worldâs cyber posture and culture will be dependent on todayâs youth, it is imperative to conduct cyber-security research with children. We conducted surveys of 189 3rd to 8th graders from two Midwest schools in the USA. We found that children have on average two passwords for school and three to four passwords for home. They kept their passwords private and did not share with others. They created passwords with an average length of 7 (3rd to 5th graders) and 10 (6â8th graders). But, only about 13% of the children created very strong passwords. Generating strong passwords requires mature cognitive and linguistic capabilities which children at this developmental stage have not yet mastered. They believed that passwords provide access control, protect their privacy and keep their âstuffâ safe. Overall, children had appropriate mental models of passwords and demonstrated good password practices. Cyber-security education should strive to reinforce these positive practices while continuing to provide and promote age-appropriate developmental security skills. Given the studyâs sample size and limited generalizability, we are expanding our research to include children from 3rd to 12th graders across multiple US school districts
Preservation Planning in Asian and Pacific Islander American Communities: A Case Study of Washington D.C.âs Chinatown
This paper explores current preservation planning practice and how traditional methods of research and survey have underserved Asian and Pacific Islander American communities in preserving both their cultural and historic resources. This paper also provides recommendations to current preservation planning practice to better serve these communities which include addressing the disparity between preservation and urban planning processes and incorporating and changing the way historic context studies and surveys are conducted and applied. Washington D.C.âs Chinatown was utilized as a case study example to critically analyze how the separation of preservation and planning processes affects the preservation and health of D.C.âs Chinatown
Effectiveness of nurse delivered endoscopy: findings from randomised multi-institution nurse endoscopy trial (MINuET)
Objective To compare the clinical effectiveness of doctors and nurses in undertaking upper and lower gastrointestinal endoscopy. Design Pragmatic trial with Zelen's randomisation before consent to minimise distortion of existing practice. Setting 23 hospitals in the United Kingdom. In six hospitals, nurses undertook both upper and lower gastrointestinal endoscopy, yielding a total of 29 centres. Participants 67 doctors and 30 nurses. Of 4964 potentially eligible patients, we randomised 4128 (83%) and recruited 1888 (38%) from July 2002 to June 2003. Interventions Diagnostic upper gastrointestinal endoscopy and flexible sigmoidoscopy, undertaken with or without sedation, with the standard preparation, techniques, and protocols of participating hospitals. After referral for either procedure, patients were randomised between doctors and nurses. Main outcome measures Gastrointestinal symptom rating questionnaire (primary outcome), gastrointestinal endoscopy satisfaction questionnaire and state-trait anxiety inventory (all analysed by intention to treat); immediate and delayed complications; quality of examination and corresponding report; patients' preferences for operator; and new diagnoses at one year (all analysed according to who carried out the procedure). Results There was no significant difference between groups in outcome at one day, one month, or one year after endoscopy, except that patients were more satisfied with nurses after one day. Nurses were also more thorough than doctors in examining the stomach and oesophagus. While quality of life scores were slightly better in patients the doctor group, this was not statistically significant. Conclusions Diagnostic endoscopy can be undertaken safely and effectively by nurses. Trial registration International standard RCT 8276570
Exploring the Benefits of Adaptive Baseball From the Parent Perspective / Exploring the Impact of the COVID-19 Pandemic on Athletes
Sports can be an integral part of a child and adolescentâs life; however, those with disabilities, regardless of severity, are less likely to participate in organized sports compared to their peers. Adaptive sports accommodate the varying ability levels of individuals through environmental modifications or the use of specialized equipment.
The purpose of this project was to understand the benefits of participation in adaptive baseball from the parent perspective to increase awareness of the sport and better inform the role occupational therapy has in helping individuals engage in meaningful occupations that promote health and well-being, social participation, and a sense of belonging.A qualitative study was performed through virtual interviews with parents from around the United States.
Themes revealed the impact participation in adaptive baseball had on the childâs sense of self-efficacy and participation in school as well as an increased sense of community and opportunity for new social relationships for both the parent and player.
This project also consisted of a separate quantitative study that focused on exploring the impact of the COVID-19 pandemic on athletes across the country to better inform the role of occupational therapy in helping athletes adjust to new life transitions within the community. The COVID-19 virus led to a global pandemic that disrupted sport participation and left many athletes with increased feelings of fear and anxiety and decreased self-identity. A quantitative study was performed through online surveys to gain the perspective of how the pandemic has impacted current athletes from across the United States.
Results highlighted the athletesâ current emotions and challenges due to reduced sport participation. Both athletes and sports organizations remain resilient and flexible towards a new normal.https://soar.usa.edu/otdcapstonesspring2021/1003/thumbnail.jp
The computer-based tutorial for a 21-point vision examination (CT21)
The Computer-based Tutorial for a 21 point vision examination (CT21) is an educational program intended to enhance optometry students\u27 knowledge and understanding of a standardized comprehensive vision exam. The program may also be used in conjunction with clinical procedures classes as an educational aid. The entire tutorial is presented in a computerized format for Macintosh computers using CD ROM. Video clips are presented along with questions for students to respond to, thereby enhancing understanding of individual components of a 21 point vision examination.

Subcutaneous adipose tissue fatty acid desaturation in adults with and without rare adipose disorders
<p>Abstract</p> <p>Background</p> <p>Elevated stearoyl-CoA desaturase activity has been described in obese states, with an increased desaturation index (DI) suggesting enhanced lipogenesis. Differences in the DI among various phenotypes of abnormal adiposity have not been studied. Abnormal accumulation of subcutaneous adipose tissue occurs in rare adipose disorders (RADs) including Dercum's disease (DD), multiple symmetric lipomatosis (MSL), and familial multiple lipomatosis (FML). Examining the DI in subcutaneous fat of people with DD, MSL and FML may provide information on adipose tissue fatty acid metabolism in these disorders. The aims of this pilot study were: 1) to determine if differences in adipose tissue DIs are present among RADs, and 2) to determine if the DIs correlate to clinical or biochemical parameters.</p> <p>Methods</p> <p>Subcutaneous adipose tissue was obtained from human participants with DD (n = 6), MSL (n = 5), FML (n = 8) and obese Controls (n = 6). Fatty acid composition was determined by gas chromatography/mass spectrometry. The DIs (palmitoleic/palmitic, oleic/stearic, vaccenic/stearic ratios) were calculated from the gas chromatogram peak intensities. SCD1 gene expression was determined. Spearman's correlations between the DIs and available clinical or biochemical data were performed.</p> <p>Results</p> <p>In DD subjects, the vaccenic/stearic index was lower (<it>p </it>< 0.05) in comparison to Controls. Percent of total of the saturated fatty acid myristic acid was higher in DD compared with Controls and FML. Percent of monounsaturated vaccenic acid in DD trended lower when compared with Controls, and was decreased in comparison to FML. In MSL, total percent of the polyunsaturated fatty acids was significantly lower than in the Control group (<it>p </it>< 0.05). In the total cohort of subjects, the palmitoleic/palmitic and oleic/stearic DIs positively correlated with age, BMI, and percent body fat.</p> <p>Conclusions</p> <p>The positive associations between the DIs and measures of adiposity (BMI and percent body fat) support increased desaturase activity in obesity. The lower vaccenic/stearic DI in DD SAT compared with Controls suggests presence of other factors involved in fat accumulation in addition to lifestyle. Other mechanisms driving fat accumulation in DD such as inflammation or lymphatic dysfunction should be investigated.</p
