Methodological Decisions in Undertaking Academic Integrity Policy Analysis: Considerations for Future Research
Purpose: The purpose of this article is to share details of the methodological decisions regarding data collection that a researcher or research team may want to consider when undertaking a policy analysis.
Methods: We have undertaken a meticulous documentation of our decision-making processes throughout the research design process.
Results: We provide narrative evidence of what worked for us as a collaborative research team.
Implications: Understanding the decisions we made throughout our research design and implementation may help other research teams, particularly those working as virtual collaborations and/or those undertaking academic integrity policy analysis
Making waves in education
Making Waves in Education is a book of a collaborative nature, being a collection of chapters written by undergraduates studying B.A. Hons in Education at the Universities of Plymouth and York. Thirteen chapters, each from a different student, cover topics from learning theories to sex education, home education and autism. The chapters are well-organised and written, and they cover key topics in an accessible and thoughtful way. The chapters are generally well - referenced and present critical and balanced arguments. Many use hard statistics in an effective way to back up their points and all include bibliographies as indeed one expects from a serious publication. The collection therefore addresses itself to a wide readership of anyone interested in education, and students and teachers/trainers in HE in particula
Human cloning in film: horror, ambivalence, hope
Fictional filmic representations of human cloning have shifted in relation to the 1997 announcement of the birth of Dolly the cloned sheep, and since therapeutic human cloning became a scientific practice in the early twentieth century. The operation and detail of these shifts can be seen through an analysis of the films The Island (2005) and Aeon Flux (2005). These films provide a site for the examination of how these changes in human cloning from fiction to practice, and from horror to hope, have been represented and imagined, and how these distinctions have operated visually in fiction, and in relation to genre
Academic Integrity Policy Analysis of Publicly-Funded Universities in Ontario, Canada: A Focus on Contract Cheating
In this article we report findings from a review of universitiesā academic integrity policies in Ontario, Canada. The research team systematically extracted, reviewed, and evaluated information from policy documents in an effort to understand how these documents described contract cheating in Ontario universities (n = 21). In all, 23 policies were examined for contract cheating language. The elements of access, approach, responsibility, detail, and support were examined and critiqued. Additionally, document type, document title and concept(s), specific contract cheating language, presence of contract cheating definitions and policy principles were reviewed. Findings revealed that none of the universitiesā policies met all of the core elements of exemplary policy, were reviewed and revised with less frequency than their college counterparts, lacked language specific to contract cheating, and were more frequently focused on punitive rather than educative approaches. These findings confirm that there is further opportunity for policy development related to the promotion of academic integrity and the prevention of contract cheating.
N-terminal pro-B-type natriuretic peptide and risk of future cognitive impairment in the REGARDS cohort
Background: Improved understanding of the etiology of cognitive impairment is needed to develop effective preventive interventions. Higher amino-terminal pro-B-type natriuretic peptide (NT-proBNP) is a biomarker of cardiac dysfunction associated with risk of cardiovascular diseases and stroke in apparently healthy people.
Objective: To study the association of NT-proBNP with risk of incident cognitive impairment.
Methods: The Reasons for Geographic and Racial Differences in Stroke is a national cohort study of 30,239 black and white Americans age 45 and older at baseline, enrolled in 2003-7. Among participants without prebaseline stroke or cognitive impairment, baseline NT-proBNP was measured in 470 cases of incident cognitive impairment and 557 controls. Cases were participants scoring below the 6th percentile of demographically-adjusted means on at least 2 of 3 serially administered tests (word list learning, word list recall and semantic fluency) over 3.5 years follow-up.
Results: Adjusting for age, gender, race, region of residence, education, and income, there was an increased odds ratio of incident cognitive impairment with increasing NT-proBNP; participants in the 4th versus 1st quartile (>127 versus ā¤33āpg/ml) had a 1.69-fold increased odds (95% CI 1.11ā2.58). Adjustment for cardiovascular risk factors and presence of an apolipoprotein E4 allele had no substantial impact on the odds ratio. Results did not differ by age, race, gender, or presence of an apolipoprotein E4 allele.
Conclusion: Higher NT-pro-BNP was associated with incident cognitive impairment in this prospective study, independent of atherogenic and Alzheimerās disease risk factors. Future work should clarify pathophysiologic connections of NT-proBNP and cognitive dysfunction
An investigation of the distribution of phosphorus between free and mineral associated soil organic matter, using density fractionation
We investigated whether density fractionation can be used to determine the distribution of organic phosphorus (OP) between free and mineral-associated soil organic matter (SOM)
The American Heart Association Life's Simple 7 and incident cognitive impairment: The REasons for Geographic And Racial Differences in Stroke (REGARDS) study
BACKGROUND: Life's Simple 7 is a new metric based on modifiable health behaviors and factors that the American Heart Association uses to promote improvements to cardiovascular health (CVH). We hypothesized that better Life's Simple 7 scores are associated with lower incidence of cognitive impairment.
METHODS AND RESULTS: For this prospective cohort study, we included REasons for Geographic And Racial Differences in Stroke (REGARDS) participants aged 45+ who had normal global cognitive status at baseline and no history of stroke (N=17 761). We calculated baseline Life's Simple 7 score (range, 0 to 14) based on smoking, diet, physical activity, body mass index, blood pressure, total cholesterol, and fasting glucose. We identified incident cognitive impairment using a 3-test measure of verbal learning, memory, and fluency obtained a mean of 4 years after baseline. Relative to the lowest tertile of Life's Simple 7 score (0 to 6 points), odds ratios of incident cognitive impairment were 0.65 (0.52, 0.81) in the middle tertile (7 to 8 points) and 0.63 (0.51, 0.79) in the highest tertile (9 to 14 points). The association was similar in blacks and whites, as well as outside and within the Southeastern stroke belt region of the United States.
CONCLUSIONS: Compared with low CVH, intermediate and high CVH were both associated with substantially lower incidence of cognitive impairment. We did not observe a dose-response pattern; people with intermediate and high levels of CVH had similar incidence of cognitive impairment. This suggests that even when high CVH is not achieved, intermediate levels of CVH are preferable to low CVH
Long-term change in calcareous grassland vegetation and drivers over three time periods between 1970 and 2016
Analysis of long-term vegetation change is limited. Furthermore most studies evaluating change only examine two snapshots in time, which makes it difficult to define rates of change and accurately assess potential drivers. To assess long-term change in calcareous grassland over multiple time periods, we re-surveyed a transect study undertaken at Parsonage Down National Nature Reserve, Wiltshire, southern England in 1970 and 1990 by T. Wells. We examined differences in soil properties and species traits in each of the survey years to understand potential drivers of vegetation change, including nitrogen deposition and grazing management. There was a clear shift in species composition, combined with significant declines in species richness and diversity between 1970 and 2016, with the greater rate of change occurring between 1990 and 2016. A significant increase in soil total nitrogen was found, which was significantly associated with the decline in species diversity between 1970 and 1990. Significant changes in community-weighted mean traits were identified for plant height (increasing), specific leaf area (decreasing), grazing tolerance (decreasing) and Ellenberg N (decreasing) between 1970 and 2016. By using survey data from multiple time periods, we suggest that N deposition may have contributed towards community changes between 1970 and 1990, as indicated by the change in soil properties and the associated decline in species diversity. Vegetation change between 1990 and 2016 is likely to be largely attributable to a decline in grazing pressure, indicated by the increase in taller species and a decrease in grazing tolerance
