A Comparison of the Attitudes of Administrators and Teachers on Cell Phone Use as an Educational Tool

Youth continue to make up the largest share of the cell phone market in the United States. In 2010, 58% of all 12 year olds owned their own cell phone. By 2015, 88% of teenagers owned a cell phone. Today’s teenagers are constantly on cell phones, using them to text, talk, access the internet, and take pictures. Technology is such a part of teenagers’ lives that they have been labeled by Marc Prensky and others as digital natives (2001). They have always had technology and cannot conceive of a world without it. School systems have faced challenges with the new technology and its adaptation for school use. Administrators and teachers have attempted to define the role of cell phones in schools. The purpose of this study was to compare the attitudes of administrators and teachers on cell phone use as an educational tool in classrooms. The attitudes of the participants were examined based on the educational role (administrator or teacher) of the participants by age, gender, years of educational experience, level of professional training in technology, cell phone ownership, and type of phone. Participant attitudes regarding perceived challenges to successful cellular technology integration were collected to bring richness to the study. The statistical analysis of the survey results revealed no significant differences in ii the attitudes of educational administrators and teachers regarding the use of cell phones in the classroom. Demographic attributes of the participants also revealed no significant differences. The research was hampered by the relatively low number of administrator responses (n=18) versus the responses from teachers (n=382). A larger collection of responses from administrators could have impacted the results of the study. While the survey results revealed no significance, the open-ended question revealed nine different themes regarding the use of technology. The most prevalent theme emphasized the importance of adequate professional training for educators in the use of cellular technology. It seems possible that the concept of cell phone use in the classroom is evolving. Educators may feel that cell phone use is inevitable, so more training is needed in how to use them for educational purposes. Further research could evaluate the effectiveness of cell phone use training and how usage could impact student achievement

Prediction of Fall Risk Among Community-Dwelling Older Adults Using a Wearable System

Falls are among the most common cause of decreased mobility and independence in older adults and rank as one of the most severe public health problems with frequent fatal consequences. In the present study, gait characteristics from 171 community-dwelling older adults were evaluated to determine their predictive ability for future falls using a wearable system. Participants wore a wearable sensor (inertial measurement unit, IMU) affixed to the sternum and performed a 10-m walking test. Measures of gait variability, complexity, and smoothness were extracted from each participant, and prospective fall incidence was evaluated over the following 6-months. Gait parameters were refined to better represent features for a random forest classifier for the fall-risk classification utilizing three experiments. The results show that the best-trained model for faller classification used both linear and nonlinear gait parameters and achieved an overall 81.6 ± 0.7% accuracy, 86.7 ± 0.5% sensitivity, 80.3 ± 0.2% specificity in the blind test. These findings augment the wearable sensor\u27s potential as an ambulatory fall risk identification tool in community-dwelling settings. Furthermore, they highlight the importance of gait features that rely less on event detection methods, and more on time series analysis techniques. Fall prevention is a critical component in older individuals’ healthcare, and simple models based on gait-related tasks and a wearable IMU sensor can determine the risk of future falls

Dynamical Properties of Postural Control in Obese Community-Dwelling Older Adults

Postural control is a key aspect in preventing falls. The aim of this study was to determine if obesity affected balance in community-dwelling older adults and serve as an indicator of fall risk. The participants were randomly assigned to receive a comprehensive geriatric assessment followed by a longitudinal assessment of their fall history. The standing postural balance was measured for 98 participants with a Body Mass Index (BMI) ranging from 18 to 63 kg/m2, using a force plate and an inertial measurement unit affixed at the sternum. Participants’ fall history was recorded over 2 years and participants with at least one fall in the prior year were classified as fallers. The results suggest that body weight/BMI is an additional risk factor for falling in elderly persons and may be an important marker for fall risk. The linear variables of postural analysis suggest that the obese fallers have significantly higher sway area and sway ranges, along with higher root mean square and standard deviation of time series. Additionally, it was found that obese fallers have lower complexity of anterior-posterior center of pressure time series. Future studies should examine more closely the combined effect of aging and obesity on dynamic balance

Mixed-methods study of risk factors and experiences of health care workers tested for the novel coronavirus in Canada

Objective: The aims of this study were to investigate occupational and non-work-related risk factors of coronavirus disease 2019 among health care workers (HCWs) in Vancouver Coastal Health, British Columbia, Canada, and to examine how HCWs described their experiences. Methods: This was a matched case-control study using data from online and phone questionnaires with optional open-ended questions completed by HCWs who sought severe acute respiratory syndrome coronavirus 2 testing between March 2020 and March 2021. Conditional logistic regression and thematic analysis were utilized. Results: Providing direct care to coronavirus disease 2019 patients during the intermediate cohort period (adjusted odds ratio, 1.90; 95% confidence interval, 1.04 to 3.46) and community exposure to a known case in the late cohort period (adjusted odds ratio, 3.595%; confidence interval, 1.86 to 6.83) were associated with higher infection odds. Suboptimal communication, mental stress, and situations perceived as unsafe were common sources of dissatisfaction. Conclusions: Varying levels of risk between occupational groups call for wider targeting of infection prevention measures. Strategies for mitigating community exposure and supporting HCW resilience are required

Infection control, occupational and public health measures including mRNA-based vaccination against SARS-CoV-2 infections to protect healthcare workers from variants of concern : a 14-month observational study using surveillance data

The article reviews evidence regarding exposure to COVID-19 in health care workers (HCW) and rates of transmission in Vancouver (Canada). Results of the study indicate that rigorous droplet-contact precautions with N95 masks for aerosol-generating procedures are effective in preventing occupational infection in HCWs, with one dose of mRNA vaccination further reducing infection risk, despite variants of concern (VOC) and transmissibility concerns. Delaying second doses to allow more widespread vaccination against severe disease, with strict public health, occupational health and infection control measures, has been effective in protecting the healthcare workforce

Protecting healthcare workers during a pandemic : what can a WHO collaborating centre research partnership contribute?

Objectives. To ascertain whether and how working as a partnership of two World Health Organization collaborating centres (WHOCCs), based respectively in the Global North and Global South, can add insights on “what works to protect healthcare workers (HCWs) during a pandemic, in what contexts, using what mechanism, to achieve what outcome”. Methods. A realist synthesis of seven projects in this research program was carried out to characterize context (C) (including researcher positionality), mechanism (M) (including service relationships) and outcome (O) in each project. An assessment was then conducted of the role of the WHOCC partnership in each study and overall. Results. The research found that lower-resourced countries with higher economic disparity, including South Africa, incurred greater occupational health risk and had less acceptable measures to protect HCWs at the onset of the COVID-19 pandemic than higher-income more-equal counterpart countries. It showed that rigorously adopting occupational health measures can indeed protect the healthcare workforce; training and preventive initiatives can reduce workplace stress; information systems are valued; and HCWs most at-risk (including care aides in the Canadian setting) can be readily identified to trigger adoption of protective actions. The C-M-O analysis showed that various ways of working through a WHOCC partnership not only enabled knowledge sharing, but allowed for triangulating results and, ultimately, initiatives for worker protection. Conclusions. The value of an international partnership on a North-South axis especially lies in providing contextualized global evidence regarding protecting HCWs as a pandemic emerges, particularly with bi-directional cross-jurisdiction participation by researchers working with practitioners.Canadian Institutes of Health Research (CIHR
