An analysis of professional practice Ed.D. dissertations in Educational Technology

The University of Florida offers an online professional practice Ed.D. focused on Educational Technology. Twenty-three students have completed professional practice dissertations and graduated since the program’s inception in 2008. The purpose of this article is to share what these dissertations have looked like and to begin a dialogue about professional practice dissertations completed in online educational technology programs. Specifically, we (1) provide an overview of different ways professional practice Ed.D. dissertations are structured, (2) share guiding principles for professional practice dissertations in our Ed.D. program, (3) analyze the ways in which these guiding principles played out in the dissertations and (4) discuss the implications of our analysis for our program and for other online professional practice programs in Educational Technology.     

The effects of the Healthy Steps for Young Children Program: results from observations of parenting and child development

The Healthy Steps for Young Children Program (HS) is designed to provide support for new parents through the pediatrician's office. We present findings of the effect of HS on the quality of mother–child interaction, security of attachment, and child behavior using observational data from two of the HS sites that utilized a randomized treatment design. Results indicated that mothers participating in Healthy Steps were more likely to interact sensitively and appropriately than mothers in the comparison group at the second assessment point (age 34–37 months) but not at the first assessment point (age 16–18 months). There were no differences in child outcomes at either time point when the cross-sectional data were analyzed. However, the results of the longitudinal analysis (which included families who participated in the home observations at both Time 1 and Time 2) indicated that Healthy Steps participation was associated with greater security of attachment and fewer child behavior problems.     

An extension of the technology acceptance model in the big data analytics system implementation environment

Research on the adoption of systems for big data analytics has drawn enormous attention in Information Systems research. This study extends big data analytics adoption research by examining the effects of system characteristics on the attitude of managers towards the usage of big data analytics systems. A research model has been proposed in this study based on an extensive review of literature pertaining to the Technology Acceptance Model, with further validation by a survey of 150 big data analytics users. Results of this survey confirm that characteristics of the big data analytics system have significant direct and indirect effects on belief in the benefits of big data analytics systems and perceived usefulness, attitude and adoption. Moreover, there are mediation effects that exist among the system characteristics, benefits of big data analytics systems, perceived usefulness and the attitude towards using big data analytics system. This study expands the existing body of knowledge on the adoption of big data analytics systems, and benefits big data analytics providers and vendors while helping in the formulation of their business models.     

Dynamic Changes in Circulatory Cytokines and Chemokines Levels in Mild to Severe COVID-19 Patients

Immune dysregulation is a key feature of the coronavirus disease-2019 (COVID-19). However, disparities in responses across ethnic groups are underappreciated. This study aimed to determine the relationship between chemokines and cytokines and the severity of COVID-19. Multiplex magnetic bead-based Luminex-100 was used to assess chemokine and cytokine levels in COVID-19 patients at admission (day-1) and after 4 days. The mean age of the patients recruited was 54.3 years, with 19 (63.3%) males. COVID-19 patients had significantly lower lymphocyte, monocyte, hemoglobin and eosinophil levels than controls (p < 0.05). COVID-19 patients showed significantly higher neutrophil levels than controls (p < 0.05). The baseline levels of IL-2, IL-6, IL-8, IL-10, and IFN-α/γ significantly increased in COVID-19 patients (p < 0.05). Chemokine levels (IP-10, MCP-1, MIG, and CCL-5) were significantly in COVID-19 patients. IL-8, IP-10, and MIG levels were significantly higher in the patients with severe COVID-19 (p < 0.05). Individuals with mild COVID-19 showed significantly higher levels of INF-α, IL-2, IL-6, and IL-8, whereas IL-10 levels were significantly lower (p < 0.05). TNF-levels decreased significantly in individuals with severe COVID-19, whereas IL-6, IL-8, and MIG levels increased (p < 0.05). After 4 days, INFα-, IL-2, IL-6, IL-8, IP-10, and MIG levels were significantly higher in patients with mild disease, whereas IL-6, MIG, and TNF-αlevels were significantly higher in patients with severe disease (p < 0.05). Thus, we conclude that COVID-19 is characterized by INF-α/γ, IL-6, IL-10, IP-10, MCP-1, MIG, and CCL5 dysregulation. IL-8, MIG, and IP-10 levels distinguish between moderate and severe COVID-19. Changes in INF-α, IL-2, IL-6, IL-8, IP-10, and MIG levels can be used to monitor disease progression.Supplementary InformationThe online version contains supplementary material available at 10.1007/s12291-022-01108-x.     

Oxidative stress in cases of chronic fluoride intoxication

This study was conducted to find out the level of oxidative stress and effect of supplementation of vitamin C, D and Calcium on levels of SOD, serum and urinary fluoride in children residing in endemic fluorosis area. For this the fluoride belt of Jaipur district was selected. The parameters selected were Super oxide dismutase, serum fluoride and urinary fluoride. The study was conducted on one hundred children, selected from four areas (25 from each area) consuming water containing 1.2, 2.4, 5.6 and 13.6 mg/l of fluoride. Drinking water fluoride, serum and urinary fluoride were measured by Ion selective electrode method. Serum SOD by Xanthine oxidase method using kit of Ransod (kit cat. No. SD125). The post treatment values showed a significant reduction in serum fluoride and SOD. Urinary fluoride levels increased significantly in post treatment stage. The results revealed a normal SOD levels in all groups but an increasing trend was observed with increasing fluoride concentration. Treatment with Calcium, Vitamin D and Vitamin C showed a significant reduction in serum fluoride and SOD and increase in urinary fluoride. A high positive correlation between pretreatment and post treatment group was observed in serum fluoride, SOD and urinary fluoride (P < 0.05). The study indicated an increasing oxidative stress in cases of fluorosis with increasing drinking water fluoride concentration. Treatment with Calcium, Vitamin D and Vitamin C resulted a significant reduction in serum fluoride and SOD and increase in urinary fluoride.     

Strategies for incorporating cultural competence into childbirth education curriculum

Cultural competence affects all interactions with prospective parents and families. Childbirth educators need to assess their own cultural competence, beginning with an understanding of their own background and how it affects interactions with families. The purpose of this article is to enhance the incorporation of cultural competency, cultural awareness, and cultural sensitivity into the childbirth education curricula. Methods for enhancing cultural competence in a multicultural global society are discussed. Strategies are also presented to address the challenges of assessing parents and families of diverse cultures and their beliefs, traditions, and special needs in the plan of care.     

Making the Critical Appraisal for Summaries of Evidence (CASE) for evidence-based medicine (EBM): critical appraisal of summaries of evidence

Objectives:

Standards for evaluating evidence-based medicine (EBM) point-of-care (POC) summaries of research are lacking. The authors developed a “Critical Appraisal for Summaries of Evidence” (CASE) worksheet to help assess the evidence in these tools. The authors then evaluated the reliability of the worksheet.

Methods:

The CASE worksheet was developed with 10 questions covering specificity, authorship, reviewers, methods, grading, clarity, citations, currency, bias, and relevancy. Two reviewers independently assessed a random selection of 384 EBM POC summaries using the worksheet. The responses of the raters were then compared using a kappa score.

Results:

The kappa statistic demonstrated an overall moderate agreement (κ = 0.44) between the reviewers using the CASE worksheet for the 384 summaries. The 3 categories of evaluation questions in which the reviewers disagreed most often were citations (κ =  0), bias (κ = 0.11), and currency (κ = −0.18).

Conclusions:

The CASE worksheet provided an effective checklist for critically analyzing a treatment summary. While the reviewers agreed on worksheet responses for most questions, variation occurred in how the raters navigated the tool and interpreted some of the questions. Further validation of the form by other groups of users should be investigated.

Highlights

• Few critical appraisal tools have been evaluated with inter-rater reliability testing.
• The ways that users of evidence-based medicine (EBM) point-of-care (POC) tools interpret how to appraise an evidence summary—particularly when defining the grading of evidence, currency, and bias—may vary even when a standard evaluation sheet is used.
• The Critical Appraisal for Summaries of Evidence (CASE) worksheet had a moderate level of inter-rater reliability, similar to previous evaluative studies of critical appraisals tools.

Implications

• Medical librarians can develop tools useful for librarians, students, and clinicians to guide them in appraising clinical evidence summaries.
• The CASE worksheet can be a valuable tool to consider the quality of individual evidence summaries and to see patterns of overall quality in EBM POC tools.
