The Life of A Reputation: The Public Memory of Ulysses S. Grant

At the time of his death in 1885, Ulysses S. Grant was widely regarded by his contemporaries as one of the great Americans of his age. Along with George Washington and Abraham Lincoln, his name was frequently included among the most accomplished heroes of the then still-young republic. Both nationally and internationally Grant was widely regarded as one of the world’s great military leaders. He was elected to the presidency of theUnited Statesduring one of the most divisive epochs in American history and won a decisive electoral victory to earn a second term. In his final years he embarked on a comprehensive world tour to great personal acclaim as well as the acknowledgement of this nation’s ascendancy as a world power. And literally hours before his death, he completed a literary work that stands today as one of the finest pieces of writing in American military history. Yet today, the remembrance of U.S. Grant bears little resemblance to the one he enjoyed among his contemporaries. As noted in a recent biography of Grant, his reputation has fallen into “disrepair.” In current popular memory, mention of Grant’s name frequently invokes images of a drunk, a failed and corrupt presidency, and a “butcher” who gained victory inAmerica’s great Civil War only as a result of superior resources and manpower. The intent of this study is to examine the evolution of Grant’s reputation from the American Civil War to recent times. It is intended to tell the story the storytellers told about Grant and how his reputation developed and was forged in popular memory. During his lifetime, this will include the study of a multitude of sources including newspaper accounts, political cartoons, diaries, and letters that reflected prevailing thought about Grant. In the years since his death, research will focus on those numerous factors that shape reputation. These will include delving into historical scholarship, literature, changing cultural nuances, political influences, and the wide range of popular entertainment vehicles so important in shaping public remembrance, to conclude with the suggestion that Grant’s reputation has been miscast in this nation’s popular memory

The scrumpled geography of literacies for learning

This paper draws upon the experience of the Literacies for Learning in Further Education research project in the UK. The project explored the literacy demands of a number of curriculum areas and the literacy practices of students in their everyday lives, in order to identify those 'border literacies' which may act as resources for learning and attainment within their college courses. Drawing on Literacy Studies and aspects of actor-network theory, this article outlines the conceptual innovations that we found necessary arising from our data analysis, extending existing work on situating practice and boundary crossing to posit a conceptual landscape that we term the scrumpled geography of literacies for learning. This landscape is one in which purification, naturalization and translation are key concepts, where literacy practices are enacted as network effects of a folding of a range of micro-practices into conglomerations

Stakeholder views on publication bias in health services research

Objectives: While the presence of publication bias in clinical research is well documented, little is known about its role in the reporting of health services research. This paper explores stakeholder perceptions and experiences with regard to the role of publication and related biases in quantitative research relating to the quality, accessibility and organization of health services. Methods: We present findings from semi-structured interviews with those responsible for the funding, publishing and/or conduct of quantitative health services research, primarily in the UK. Additional data collection includes interviews with health care decision makers as ‘end users’ of health services research, and a focus group with patient and service user representatives. The final sample comprised 24 interviews and eight focus group participants. Results: Many study participants felt unable to say with any degree of certainty whether publication bias represents a significant problem in quantitative health services research. Participants drew broad contrasts between externally funded and peer reviewed research on the one hand, and end user funded quality improvement projects on the other, with the latter perceived as more vulnerable to selective publication and author over-claiming. Multiple study objectives, and a general acceptance of ‘mess and noise’ in the data and its interpretation was seen to reduce the importance attached to replicable estimates of effect sizes in health services research. The relative absence of external scrutiny, either from manufacturers of interventions or health system decision makers, added to this general sense of ‘low stakes’ of health services research. As a result, while many participants advocated study pre-registration and using protocols to pre-identify outcomes, others saw this as an unwarranted imposition. Conclusions: This study finds that incentives towards publication and related bias are likely to be present, but not to the same degree as in clinical research. In health services research, these were seen as being offset by other forms of ‘novelty’ bias in the reporting and publishing of research findings

Assessment of publication bias and outcome reporting bias in systematic reviews of health services and delivery research:A meta-epidemiological study

Strategies to identify and mitigate publication bias and outcome reporting bias are frequently adopted in systematic reviews of clinical interventions but it is not clear how often these are applied in systematic reviews relating to quantitative health services and delivery research (HSDR). We examined whether these biases are mentioned and/or otherwise assessed in HSDR systematic reviews, and evaluated associating factors to inform future practice. We randomly selected 200 quantitative HSDR systematic reviews published in the English language from 2007-2017 from the Health Systems Evidence database (www.healthsystemsevidence.org). We extracted data on factors that may influence whether or not authors mention and/or assess publication bias or outcome reporting bias. We found that 43% (n = 85) of the reviews mentioned publication bias and 10% (n = 19) formally assessed it. Outcome reporting bias was mentioned and assessed in 17% (n = 34) of all the systematic reviews. Insufficient number of studies, heterogeneity and lack of pre-registered protocols were the most commonly reported impediments to assessing the biases. In multivariable logistic regression models, both mentioning and formal assessment of publication bias were associated with: inclusion of a meta-analysis; being a review of intervention rather than association studies; higher journal impact factor, and; reporting the use of systematic review guidelines. Assessment of outcome reporting bias was associated with: being an intervention review; authors reporting the use of Grading of Recommendations, Assessment, Development and Evaluations (GRADE), and; inclusion of only controlled trials. Publication bias and outcome reporting bias are infrequently assessed in HSDR systematic reviews. This may reflect the inherent heterogeneity of HSDR evidence and different methodological approaches to synthesising the evidence, lack of awareness of such biases, limits of current tools and lack of pre-registered study protocols for assessing such biases. Strategies to help raise awareness of the biases, and methods to minimise their occurrence and mitigate their impacts on HSDR systematic reviews, are needed

Compassion satisfaction and fatigue: An investigation into levels being reported by radiotherapy students

Introduction: Studies have investigated the prevalence of compassion satisfaction and compassion fatigue in various healthcare professions. However, the majority of evidence is linked to the nursing profession and little is known about paramedical professions such as radiography and even less is known about its prevalence in students. The purpose of this study was to describe the levels of compassion satisfaction and compassion fatigue in the student population and how they varied in time. Methods: Students undertaking radiotherapy training at the researcher’s host sites were surveyed using the Professional Quality of Life questionnaire at the end of each final clinical bock in each year of their training. Results & Conclusion: During the three years of training compassion satisfaction falls and burnout increases in the student population, although the change is not significant. Secondary traumatic stress increases significantly during the 3 years of training, F=5.725, p=0.005. Considerable variation also exists in the three scores dependent on the student’s clinical training site. Relationships are also observed between some personality traits, particularly conscientiousness and neuroticism and compassion scores

Preservational bias controls the fossil record of pterosaurs

Pterosaurs, a Mesozoic group of flying archosaurs, have become a focal point for debates pertaining to the impact of sampling biases on our reading of the fossil record, as well as the utility of sampling proxies in palaeodiversity reconstructions. The completeness of the pterosaur fossil specimens themselves potentially provides additional information that is not captured in existing sampling proxies, and might shed new light on the group’s evolutionary history. Here we assess the quality of the pterosaur fossil record via a character completeness metric based on the number of phylogenetic characters that can be scored for all known skeletons of 172 valid species, with averaged completeness values calculated for each geological stage. The fossil record of pterosaurs is observed to be strongly influenced by the occurrence and distribution of Lagerstätten. Peaks in completeness correlate with Lagerstätten deposits, and a recovered correlation between completeness and observed diversity is rendered non-significant when Lagerstätten species are excluded. Intervals previously regarded as potential extinction events are shown to lack Lagerstätten and exhibit low completeness values: as such, the apparent low diversity in these intervals might be at least partly the result of poor fossil record quality. A positive correlation between temporal patterns in completeness of Cretaceous pterosaurs and birds further demonstrates the prominent role that Lagerstätten deposits have on the preservation of smaller bodied organisms, contrasting with a lack of correlation with the completeness of large-bodied sauropodomorphs. However, we unexpectedly find a strong correlation between sauropodomorph and pterosaur completeness within the Triassic–Jurassic, but not the Cretaceous, potentially relating to a shared shift in environmental preference and thus preservation style through time. This study highlights the importance of understanding the relationship between various taphonomic controls when correcting for sampling bias, and provides additional evidence for the prominent role of sampling on observed patterns in pterosaur macroevolution

A comparison of semi-automated volumetric vs linear measurement of small vestibular schwannomas.

OBJECTIVE: Accurate and precise measurement of vestibular schwannoma (VS) size is key to clinical management decisions. Linear measurements are used in routine clinical practice but are prone to measurement error. This study aims to compare a semi-automated volume segmentation tool against standard linear method for measuring small VS. This study also examines whether oblique tumour orientation can contribute to linear measurement error. STUDY DESIGN: Experimental comparison of observer agreement using two measurement techniques. SETTING: Tertiary skull base unit. PARTICIPANTS: Twenty-four patients with unilateral sporadic small (< 15 mm maximum intracranial dimension) VS imaged with 1 mm-thickness T1-weighted Gadolinium enhanced MRI. MAIN OUTCOME MEASURES: (1) Intra and inter-observer intraclass correlation coefficients (ICC), repeatability coefficients (RC), and relative smallest detectable difference (%SDD). (2) Mean change in maximum linear dimension following reformatting to correct for oblique orientation of VS. RESULTS: Intra-observer ICC was higher for semi-automated volumetric when compared with linear measurements, 0.998 (95% CI 0.994-0.999) vs 0.936 (95% CI 0.856-0.972), p < 0.0001. Inter-observer ICC was also higher for volumetric vs linear measurements, 0.989 (95% CI 0.975-0.995) vs 0.946 (95% CI 0.880-0.976), p = 0.0045. The intra-observer %SDD was similar for volumetric and linear measurements, 9.9% vs 11.8%. However, the inter-observer %SDD was greater for volumetric than linear measurements, 20.1% vs 10.6%. Following oblique reformatting to correct tumour angulation, the mean increase in size was 1.14 mm (p = 0.04). CONCLUSION: Semi-automated volumetric measurements are more repeatable than linear measurements when measuring small VS and should be considered for use in clinical practice. Oblique orientation of VS may contribute to linear measurement error

A temperate palaeodiversity peak in Mesozoic dinosaurs and evidence for Late Cretaceous geographical partitioning

Aim  Modern biodiversity peaks in the tropics and declines poleward, a pattern that is potentially driven by climate. Although this latitudinal biodiversity gradient (LBG) also characterizes the marine invertebrate fossil record, distributions of ancient terrestrial faunas are poorly understood. This study utilizes data on the dinosaur fossil record to examine spatial patterns in terrestrial biodiversity throughout the Mesozoic.\ud Location  We compiled data on fossil occurrences across the globe.\ud Methods  We compiled a comprehensive dataset of Mesozoic dinosaur genera (738), including birds. Following the utilization of sampling standardization techniques to mediate for the uneven sampling of the fossil record, we constructed latitudinal patterns of biodiversity from this dataset.\ud Results  The dominant group of Mesozoic terrestrial vertebrates did not conform to the modern LBG. Instead, dinosaur diversity was highest at temperate palaeolatitudes throughout the 160 million year span of dinosaurian evolutionary history. Latitudinal diversity correlates strongly with the distribution of land area. Late Cretaceous sauropods and ornithischians exhibit disparate LBGs.\ud Main conclusions  The continuity of the palaeotemperate peak in dinosaur diversity indicates a diminished role for climate on the Mesozoic LBG; instead, dinosaur diversity may have been driven by the amount of land area among latitudinal belts. There is no evidence that the tropics acted as a cradle for dinosaur diversity. Geographical partitioning among major clades of herbivorous dinosaurs in the Late Cretaceous may result from the advanced stages of continental fragmentation and/or differing responses to increasing latitudinal climatic zonation. Our results suggest that the modern-day LBG on land was only established 30 million years ago, following a significant post-Eocene recalibration, potentially related to increased seasonality
