Word Frequencies

The new forms of written online communication offer a great resource for researchers interested in language variation and use, but more large-scale systematic research into the nature of the data is needed. For instance, Swedish blog data is often described as more informal and spoken in nature than traditional edited written material but overall systematic comparisons are lacking. This short communication contributes systematic comparisons between blog data and spoken and written registers by comparing measures such as type/token ratios and word frequencies. Type/token ratios of blog texts are found to lie between those for interactive speech and formal edited writing, whereas the distribution of words from different frequency bands is closer to the written material. Comparison of the ten most frequent word forms indicates that blog data resembles formal edited writing from a structural perspective, but also suggests that further studies into features of personal involvement may provide additional insights.

Currently, the soil-aggregate mixture has been widely used in some large-scale site preparation projects, compaction characteristics has been pay more attention by many engineers and researchers. However, systematic research is insufficient on how to choose the filler. Moreover, some industry regulations are different on the requirements about filler. This paper relies on a certain big site preparation projects, discussing statistical characteristics and correlation on the maximal grain size, contents of the coarse grain, gradation and other parameters of soil-aggregate mixture. The results show that the maximal and the median grain size have small discreteness and normal distribution, indicating site filler is easy to reach the requirement; The coefficient of curvature, coefficient of nonuniformity and the coarse grain content have large discreteness, and dont obey normal distribution, indicating the filler has large variability. The median grain size is highly relevant to the coarse grain content; the maximal grain size isnt relevant to the coefficient of nonuniformity, the coefficient of curvature and the coarse grain content. According to the results of correlation analysis, we suggest that the importance order follow by coarse grain content, the maximum grain size and gradation for the control parameters of filler. This research may be significant to other similar projects.

To solve the problems they face, online communities adopt comprehensive governance methods including committees, boards, juries, and even more complex institutional logics. Helping these kinds of communities succeed will require categorizing best practices and creating toolboxes that fit the needs of specific communities. Beyond such applied uses, there is also a potential for an institutional logic itself to evolve, taking advantage of feedback provided by the fast pace and large ecosystem of online communication. Here, we outline an experimental strategy aiming at guiding and facilitating such an evolution. We first review the advantages of studying collective action using recent technologies for efficiently orchestrating massive online experiments. Research in this vein includes attempts to understand how behavior spreads, how cooperation evolves, and how the wisdom of the crowd can be improved. We then present the potential usefulness of developing virtual-world experiments with governance for improving the utility of social feedback. Such experiments can be used for improving community rating systems and monitoring (dashboard) systems. Finally, we present a framework for constructing large-scale experiments entirely in virtual worlds, aimed at capturing the complexity of governance dynamics, to empirically test outcomes of manipulating institutional logic.

BackgroundWith the large-scale introduction of volumetric modulated arc therapy (VMAT), selection of optimal beam angles for coplanar static-beam IMRT has increasingly become obsolete. Due to unavailability of VMAT in current MR-linacs, the problem has re-gained importance. An application for automated IMRT treatment planning with integrated, patient-specific computer-optimization of beam angles (BAO) was used to systematically investigate computer-aided generation of beam angle class solutions (CS) for replacement of computationally expensive patient-specific BAO. Rectal cancer was used as a model case.Materials and Methods23 patients treated at a Unity MR-linac were included. BAOx plans (x=7-12 beams) were generated for all patients. Analyses of BAO12 plans resulted in CSx class solutions. BAOx plans, CSx plans, and plans with equi-angular setups (EQUIx, x=9-56) were mutually compared.ResultsFor x>7, plan quality for CSx and BAOx was highly similar, while both were superior to EQUIx. E.g. with CS9, bowel/bladder Dmean reduced by 22% [11%, 38%] compared to EQUI9 (p<0.001). For equal plan quality, the number of EQUI beams had to be doubled compared to BAO and CS.ConclusionsComputer-generated beam angle CS could replace individualized BAO without loss in plan quality, while reducing planning complexity and calculation times, and resulting in a simpler clinical workflow. CS and BAO largely outperformed equi-angular treatment. With the developed CS, time consuming beam angle re-optimization in daily adaptive MR-linac treatment could be avoided. Further systematic research on computerized development of beam angle class solutions for MR-linac treatment planning is warranted.

Accountability Gap

Abstract Growing concerns about the quality of aggregated biodiversity data are lowering trust in large-scale data networks. Aggregators frequently respond to quality concerns by recommending that biologists work with original data providers to correct errors ‘at the source.’ We show that this strategy falls systematically short of a full diagnosis of the underlying causes of distrust. In particular, trust in an aggregator is not just a feature of the data signal quality provided by the sources to the aggregator, but also a consequence of the social design of the aggregation process and the resulting power balance between individual data contributors and aggregators. The latter have created an accountability gap by downplaying the authorship and significance of the taxonomic hierarchies—frequently called ‘backbones’—they generate, and which are in effect novel classification theories that operate at the core of data-structuring process. The Darwin Core standard for sharing occurrence records plays an under-appreciated role in maintaining the accountability gap, because this standard lacks the syntactic structure needed to preserve the taxonomic coherence of data packages submitted for aggregation, potentially leading to inferences that no individual source would support. Since high-quality data packages can mirror competing and conflicting classifications, i.e. unsettled systematic research, this plurality must be accommodated in the design of biodiversity data integration. Looking forward, a key directive is to develop new technical pathways and social incentives for experts to contribute directly to the validation of taxonomically coherent data packages as part of a greater, trustworthy aggregation process.

Bipolar disorder (BD) is a chronic illness with a relapsing and remitting time course. Relapses are manic or depressive in nature and intermitted by euthymic states. During euthymic states, patients lack the criteria for a manic or depressive diagnosis, but still suffer from impaired cognitive functioning as indicated by difficulties in executive and language-related processing. The present study investigated whether these deficits are reflected by altered intracortical activity in or functional connectivity between brain regions involved in these processes such as the prefrontal and the temporal cortices. Vigilance-controlled resting state EEG of 13 euthymic BD patients and 13 healthy age- and sex-matched controls was analyzed. Head-surface EEG was recomputed into intracortical current density values in 8 frequency bands using standardized low-resolution electromagnetic tomography. Intracortical current densities were averaged in 19 evenly distributed regions of interest (ROIs). Lagged coherences were computed between each pair of ROIs. Source activity and coherence measures between patients and controls were compared (paired t tests). Reductions in temporal cortex activity and in large-scale functional connectivity in patients compared to controls were observed. Activity reductions affected all 8 EEG frequency bands. Functional connectivity reductions affected the delta, theta, alpha-2, beta-2, and gamma band and involved but were not limited to prefrontal and temporal ROIs. The findings show reduced activation of the temporal cortex and reduced coordination between many brain regions in BD euthymia. These activation and connectivity changes may disturb the continuous frontotemporal information flow required for executive and language-related processing, which is impaired in euthymic BD patients.

Garden-based education is a philosophical orientation to teaching and learning that uses gardens as the milieu for student engagement through meaningful and relevant curricular and instructional integration in schools. In addition to their direct academic appeal in raising test scores and grades, particularly in science, language arts, and math, gardens on educational campuses, spanning pre-school through high school, are also utilized by educators for a variety of other outcomes. These include motivational engagement; social, moral, and emotional development; strengthening of institutional and community bonds; vocational skills development; food literacy; healthy eating habits; and holistic growth of children and youth. Moreover, garden-based education shows promise as a tangible and pragmatic solution to address problems of disaffection and disengagement among youth that has resulted in a school dropout crisis in many places. While specific to higher education, farm-based education and agriculture-based education that focus on growing food have parallel agendas. The vast array of outcomes linked with garden-based education may seem impressive. However, systematic research studies of garden-based education across sites to measure educational impact are missing, largely due to their marginalized status and the decentralized and localized nature of program implementation and professional training. While the idea of including gardens on educational campuses to grow food or to serve as a means of outdoor and nature education is not new, since the 1990s, there has been a surge of interest in using garden-based education across countries and continents. With its accessibility on school grounds, garden-based education intersects with parallel movements such as outdoor education, place-based education, experiential education, nature-based education, environmental education, and sustainability education. Manifested in a variety of grassroots practices that include slow food, community supported agriculture, edible schoolyards, global roots, indigenous cultural gardens, learning gardens, lifelab, living classrooms, multicultural school gardens, urban harvest, and more, gardens will likely continue to be of significance in education as there are growing uncertainties globally about food security and health matters related to climate change. Despite high stakes, standardized tests, and accountability measures that pose challenges to educators and proponents of school gardens in public schools, research shows their promise as laboratories for innovation and academic learning. Garden-based education would benefit if informed by longitudinal and large-scale research studies that demonstrate instructional and curricular rigor and integration and impact on learning outcomes. Drawing on critical and posthumanist theories that question the nature of schooling, and explicitly addressing issues of race, class, and perspectives of marginalized and indigenous scholars and practitioners would bring further credence. Practice-embedded research and co-production of knowledge that accepts complexity and conjunctive thinking, while also addressing culturally responsive pedagogy across socio-economic status, would enhance the viability of this growing movement.

Abstract Objective Spread through air space (STAS) is a novel invasive pattern of lung adenocarcinoma and is also a risk factor for recurrence and worse prognosis of lung adenocarcinoma after sublobar resection. The aims of this study are to evaluate the association between computed tomography (CT)-based features and STAS for preoperative prediction of STAS in lung adenocarcinoma, eventually, which could help us choose appropriate surgical type. Methods Systematic research was conducted to search for studies published before September 1, 2019. The association between CT-based features of radiological tumor size>2 cm、pure solid nodule、 part-solid nodule or Percentage of solid component (PSC)>50% and STAS was evaluated. According to rigorous inclusion and exclusion criteria. Eight studies including 2385 patients published between 2015 and 2018 were finally enrolled in our meta-analysis. Results Our results clearly depicted that there is no significant relationship between radiological tumor size>2 cm and STAS with the combined OR of 1.47(95% CI:0.86–2.51). Meta-analysis of 3 studies showed that pure solid nodule in CT image were more likely to spread through air spaces with pooled OR of 3.10(95%CI2.17–4.43). Meta-analysis of 5 studies revealed the part-solid nodule in CT image may be more likely to appear STAS in adenocarcinoma (ADC) (combined OR:3.10,95%CI:2.17–4.43). PSC>50% in CT image was a significant independent predictor in the diagnosis of STAS in ADC from our meta-analysis with combined OR of 2.95(95%CI:1.88–4.63). Conclusion In conclusion, The CT-based features of pure solid nodule、part-solid nodule、PSC>50% are promising imaging biomarkers for predicting STAS in ADC and may substantially influence the choice of surgical type. In future, more studies with well-designed and large-scale are needed to confirm the conclusion.

Abstract The Rio Grande Valley (RGV) has been impacted by various hurricanes throughout history. While Hurricane evacuation has been studied extensively in other contexts, there is limited systematic research on the warning and response to a large-scale severe weather event in South Texas. This study attempts to understand the evacuation decision-making behavior of Southern residents in the event of a Hurricane making landfall over the Rio Grande Valley. The study uses an online survey questionnaire with 1060 participants: 275 students attending the University of Texas-Rio Grande Valley and the remaining 785 are members of the community. Throughout the course of the study, information was gathered about selected elements: demographic characteristics, living conditions, the following and awareness of authority recommendations, decision maker roles, reasons for not wanting to leave a disaster-prone area facing an emergency, perception of a safe place, and expected help from both, governments and non-governmental organizations (NGOs) during evacuation that could impact residents’ evacuation decision. Findings reveal there are a number of individuals who will remain in their place of residence, even in the deadliest of hurricane Category 5. The study provides complex factors influencing the nature of evacuation decision-making of individuals who are Hispanics living in a unique geographical location of RGV.

Fifty years ago, when the founders of this Society looked to the future of Roman studies, the general lines of development in Republican history must have seemed fairly clear. On the technical side Mommsen had opened up the main fields of systematic research, Eduard Meyer was at the height of his influence, and Beloch was testing new methods of historical survey, while Niese had arranged the evidence for Hellenistic politics. Historical scholarship could face a great access of material with confidence, as archaeology and epigraphy extended its scope, though this was less likely to affect Republican than Imperial history. At the same time the problems of historical interpretation had taken shape; for the events of the nineteenth century illustrated the play of power politics, which were relevant to the understanding of Roman imperialism. The ‘economic’ interpretation of history was coming into vogue, and this could lead into ‘social history’. If the influence of family connections and personal ambition was felt less urgently, it could be argued that a ‘scientific’ analysis of Roman politics should probe more deeply into the forces that broke out in the constitutional crisis of the Late Republic. We may admit at once that the main work in Republican history during our period has continued along these lines : we are still heavily in debt to the fundamental study of the older masters. The concept of ‘scientific’ history may have been modified, since it is a task of complicated inference to arrive at historical knowledge; yet the actual methods to which we have succeeded are well fitted for the systematic treatment of detailed evidence. Collingwood did less than justice to the school of Mommsen when he charged it with mastery over small-scale problems but weakness in dealing with large-scale ones. Only strict analysis and reconstruction of the evidence allowed the chief issues of Republican history to be defined critically, and subsequent research has refined on this procedure.
