Variables and Design Elements
Original Research Question: Did implementing remote and virtual front desk services, including live representatives via webcam, impact staffing efficacy for underserved patients, especially patients with English as their second language in FQHCs post-pandemic?
Population of Interest
The total clinic population of adults (both male and female) aged between 20 and 60 at four selected FQHCs in Los Angeles County, California between January and October 2023. The sample size is 400 patients, 100 from each of the four FQHCs.
Sample Size Determination:
The sample size is determined by Charan and Biswas (2013) formula for comparing two groups based on quantitative data.
Sample size = where SD is the standard deviation from past studies and d is the effect size (Charan & Biswas, 2013).
Sample size = = 100
Proposed Research Design
The study adopts a placebo-controlled trial design, where there are at least two groups, with one receiving the active intervention and the other the placebo.
The researcher will compare patient visit and no-show rates in two FQHCs that have implemented remote and virtual front desk services, including live representatives via webcam (intervention), and two that have not implemented such telehealth programs (placebo).
Proposed Methods
Data on overall patient visits by specialty group (preventive services,
Test Statistic
One way analysis of variance (ANOVA)
Independent Variables
Implementation of virtual front desks and live representatives (Yes/No), Gender (Male/Female), primary language (English/non-English), Ethnicity/Race (White, Black, Asian, Latino, Other), and Insurance payer (Private/Medicaid/Medicare).
Dependent Variable
Staffing efficacy, measured by patient numbers and no-show rates.
Hypothesis:
FQHCs that implement virtual front desks and live representative programs report significantly higher staffing efficacy for underserved patients, especially ESL patients, than those that do not implement such programs.
(1 ? 2)
There is no significant difference in staffing efficacy between FQHCs that implement virtual front desks and live representatives and those that do…

Peer-reviewed articles are valuable sources of scholarly information. They provide quality, objective, and accurate information on various topics. This is achieved by subjecting the articles to rigorous scrutiny by peer researchers, hence the name peer-reviewed. Though there are variations in how research articles are formatted, there are standardised elements that appear in every article irrespective of the format. A peer-reviewed article must on the minimum have a title, details of
Journal Article: Design and Modeling of a Textile Pressure Sensor for Sitting Posture ClassificationSummaryIt is important to note, from the onset, that the relevance of analyzing siting posture cannot be overstated in healthcare and biomedical realms. For this reason, there is need to develop posture monitoring systems that are not only confortable, but also economical and more efficient. Towards this end, Meyer, Arnrich, Schumm, and Troster suggest a textile pressure
women's entrepreneurs: Evidence from an East African Economy (Ethiopia) It is an established fact that the Micro and Small Enterprise (MSE) sectors can help large parts of the populace in underdeveloped economies like Ethiopia as the means for livelihood. African women are beleaguered with societal and cultural challenges and overall entrepreneurial attributes, and that is reflected in the lack of their entrepreneurship development. This study hence takes up the issues
Miniature Antennas for Biomedical Applications Most of the studies on microwave antennas for medical applications have concentrated on generating hyperthermia for medical treatments and monitoring several physiological parameters. The types of antenna implanted depend of the location. Besides the medical therapy and diagnosis the telecommunications are considered as significant functions for implantable medical devices those needs to transmit diagnosis information. The design of the antennas catering to MEMS and NANO
Eveland's research design is quasi-experimental. The sample populations for the experiment are not randomly selected. There is structure to the experiment with more than one form of measurement during the research process. Quasi-experimental design includes multiple groups and multiple waves of measurement. While there were not a significant number of groups in the experiment, there was more than one. At more than one point in the experiment, measurements were
