Africa's Living Rivers: Managing for Sustainability
Authors: King Jackie , Brown Cate 
Published: September 2021

Abstract
Africa's human population is growing rapidly and is set to account for 40 percent of global numbers by 2100. Further development of its inland waters, to enhance water and energy security, is inevitable. Will it follow the development pathway of industrialized countries, often destructive of ecosystems, biodiversity, and river-dependent social structures, or can it chart a new way into the future based on global lessons of equity and sustainability? This essay tracks the global and African growth of the benefits and costs of water resource developments, explores the reasons for the costs, and offers insights on new scientific thinking that can help guide Africa to a more sustainable future.
Climate & Water in a Changing Africa: Uncertainty, Adaptation & the Social Construction of Fragile Environments
Authors: Verhoeven Harry 
Published: September 2021

Abstract
Discussions of climate change and water security in Africa are often simplistic and indeed deterministic. They overlook not only ecological complexities but also the multitude of ways in which various population groups across the continent approach climatological variability, thereby challenging positivist modeling and external adaptation agendas. The current state of affairs for many often-silenced citizens is already one of hunger, uncertainty, and marginalization; the self-appointed lead actors on climate adaptation–states, markets, NGOs–have, from their vantage point, deeply troubling track records of dealing with people and their environments. For plenty of communities around Africa, it might therefore not so much be only the worsening climate that is increasingly exposing people to disease, displacement, and water insecurity, but the very policies adopted in the name of preparing for, and living with, worsening weather. This essay explores how understanding climate adaptation as a fundamentally social and political process points to possibilities for imagining and working toward futures with greater emancipatory potential. There is no scenario in which African societies adapt successfully to climatic change and do not simultaneously radically reimagine both their relationship with the outside world and with each other, including institutions of control and mechanisms of exclusion at home.
Context-aware Adversarial Training for Name Regularity Bias in Named Entity Recognition

Published: September 2021

AbstractIn this work, we examine the ability of NER models to use contextual information when predicting the type of an ambiguous entity. We introduce NRB, a new testbed carefully designed to diagnose Name Regularity Bias of NER models. Our results indicate that all state-of-the-art models we tested show such a bias; BERT fine-tuned models significantly outperforming feature-based (LSTM-CRF) ones on NRB, despite having comparable (sometimes lower) performance on standard benchmarks.To mitigate this bias, we propose a novel model-agnostic training method that adds learnable adversarial noise to some entity mentions, thus enforcing models to focus more strongly on the contextual signal, leading to significant gains on NRB. Combining it with two other training strategies, data augmentation and parameter freezing, leads to further gains.
Soloist: BuildingTask Bots at Scale with Transfer Learning and Machine Teaching

Published: September 2021

AbstractWe present a new method, Soloist,1 that uses transfer learning and machine teaching to build task bots at scale. We parameterize classical modular task-oriented dialog systems using a Transformer-based auto-regressive language model, which subsumes different dialog modules into a single neural model. We pre-train, on heterogeneous dialog corpora, a task-grounded response generation model, which can generate dialog responses grounded in user goals and real-world knowledge for task completion. The pre-trained model can be efficiently adapted to accomplish new tasks with a handful of task-specific dialogs via machine teaching, where training samples are generated by human teachers interacting with the system. Experiments show that (i)Soloist creates new state-of-the-art on well-studied task-oriented dialog benchmarks, including CamRest676 and MultiWOZ; (ii) in the few-shot fine-tuning settings, Soloist significantly outperforms existing methods; and (iii) the use of machine teaching substantially reduces the labeling cost of fine-tuning. The pre-trained models and codes are available at https://aka.ms/soloist.
Neural Event Semantics for Grounded Language Understanding
Authors: Buch Shyamal , Fei-Fei Li , Goodman Noah D. 
Published: September 2021

AbstractWe present a new conjunctivist framework, neural event semantics (NES), for compositional grounded language understanding. Our approach treats all words as classifiers that compose to form a sentence meaning by multiplying output scores. These classifiers apply to spatial regions (events) and NES derives its semantic structure from language by routing events to different classifier argument inputs via soft attention. NES is trainable end-to-end by gradient descent with minimal supervision. We evaluate our method on compositional grounded language tasks in controlled synthetic and real-world settings. NES offers stronger generalization capability than standard function-based compositional frameworks, while improving accuracy over state-of-the-art neural methods on real-world language tasks.
Relevance-guided Supervision for OpenQA with ColBERT
Authors: Khattab Omar , Potts Christopher , Zaharia Matei 
Published: September 2021

Abstract
Systems for Open-Domain Question Answering (OpenQA) generally depend on a retriever for finding candidate passages in a large corpus and a reader for extracting answers from those passages. In much recent work, the retriever is a learned component that uses coarse-grained vector representations of questions and passages. We argue that this modeling choice is insufficiently expressive for dealing with the complexity of natural language questions. To address this, we define ColBERT-QA, which adapts the scalable neural retrieval model ColBERT to OpenQA. ColBERT creates fine-grained interactions between questions and passages. We propose an efficient weak supervision strategy that iteratively uses ColBERT to create its own training data. This greatly improves OpenQA retrieval on Natural Questions, SQuAD, and TriviaQA, and the resulting system attains state-of-the-art extractive OpenQA performance on all three datasets.
Traumatic Pediatric Tracheal Rupture After Blunt Force Sporting Injury: Case Report and Review of the Literature
Authors: Taylor Alon , Menon Seema , Grant Peter , Currie Bruce , Soma Marlene 
Published: September 2021

Objective: This paper presents the case of a traumatic tracheal rupture in a pediatric patient. The body of literature of the clinical features, evaluation, and management of this uncommon presentation is discussed. Case: A 13-year-old boy sustained an intrathoracic tracheal rupture whilst playing Australian Rules football. He developed hallmark clinical features of air extravasation and was intubated prior to transfer to a tertiary pediatric center for further management. After a short trial of conservative management, his respiratory status deteriorated and he was taken to the operating theater for open surgical repair of the defect. Conclusion: Traumatic rupture of the trachea is a rare injury in children. This case demonstrates the dynamic nature of this serious injury and the need for multidisciplinary care in achieving the optimal outcome.

Authors: Brandín-de la Cruz Natalia , Calvo Sandra , Rodríguez-Blanco Cleofás , Herrero Pablo , Bravo-Esteban Elisabeth 
Published: September 2021

Background: Alterations in gait and muscular rigidity are common and disabling in persons with Parkinson’s disease (PD). Objective: The aim of this study was to determine whether a single dry needling (DN) session can promote changes in gait and muscle tone in the lower extremities as well as in the evolution of the disease in persons with PD. Methods: A randomized double-blind clinical trial was designed. Participants were randomly assigned to an intervention group (IG) that received a session of DN over the semitendinosus, medial gastrocnemius, soleus and rectus femoris muscles, or to a control group (CG) that received a session of sham DN in the same muscles. The effects of DN were assessed using the timed up and go test (TUG), 10 meter walk test (10MWT), 6 minute walk test (6MWT) and myotonometry before, immediately after, and 7 days after the intervention. Results: Thirty-three participants were analyzed aged 69.9 ± 7.2 years (mean ± SD; 39% female). There were no significant differences between the IG and CG for any outcomes. Significant differences were observed when comparing the Pre and Follow-up values in the IG for functional mobility of gait in the TUG (p = 0.049), gait speed in the 10MWT (p = 0.041) and muscle tone in the lower extremities by myotonometry (frequency (p = 0.027) and stiffness (p = 0.013)). By comparison, there were no significant within-group differences in the CG. Conclusion: A single session of DN had no measurable benefit compared to a single session of sham DN. Within-group changes in the IG suggested improvements in functional mobility of gait and gait speed, as well as changes in the muscle tone in the lower extremities of PD patients, which could be worthy of further exploration by future research.

Published: September 2021

Objectives Up-to-date information on the current practices and attitudes of veterinarians in Australia to acute pain management in cats was sought in 2017–2018 in the first nationwide survey in over 20 years. Methods An online survey was created, consisting of 54 questions in four sections, with 18 feline-specific questions. Veterinarians throughout Australia were invited to participate in the survey through advertisements in the veterinary press, electronic and regular mail, and through in-clinic visits and promotional materials. Results A total of 614 veterinarians completed the survey, with 513 (83.6%) completing the feline-specific section. The demographics of the respondents of this survey were an accurate representation of the registered veterinarians in Australia at the time. Multiple different opioids and non-steroidal anti-inflammatory drugs (NSAIDs) were widely available in practices to manage pain, with analgesic efficacy reported as the primary factor influencing drug selection. Opioids were most commonly used in the preoperative period and NSAIDs were most commonly used postoperatively. Despite the wide availability in clinic (>99%), only 55% of respondents reported regularly using local anaesthetic techniques in cats. Pain assessment of hospitalised patients was primarily performed by veterinarians (91.1%); however, 84.7% of respondents did not routinely use a validated pain scale. Conclusions and relevance Veterinary practitioners in Australia are adequately equipped with analgesic medication to treat pain in their patients. In the management of acute pain in cats, they frequently use a multimodal approach and practice a variety of analgesic protocols. Based on the results of this survey, potential areas for improvement in feline pain management include an increase in duration of postoperative analgesia and more routine use of validated pain scales, performed by nurses and veterinarians alike, to assess individual analgesic needs.

Published: September 2021

Introduction: Total Hip Arthroplasty (THA) is being increasingly undertaken in younger and more active patients, with many of these patients wanting to return to sport (RTS) after surgery. However, the percentage of patients RTS and time at which they are able to get back to sport following surgery remains unknown. The objective of this meta-analysis was to determine the time patients RTS after THA. Methods: A search was performed on PUBMED, MEDLINE, EMBASE, and the Cochrane Library for trials on THA and RTS, in the English language, published from the inception of the database to October 2020. All clinical trials reporting on to RTS following THA were included. Data relating to patient demographics, methodological quality, RTS, clinical outcomes and complications were recorded. The PRISMA guidelines were used to undertake this study. Results: The initial literature search identified 1720 studies. Of these, 11 studies with 2297 patients matched the inclusion criteria. 3 studies with 154 patients demonstrated an overall pooled proportion of 40.0% (95% CI, 32.5–47.9%) of patients RTS between 2 and 3 months after surgery. 4 studies with 242 patients demonstrated an overall pooled proportion of 76.9% (95% CI, 71.5–82.0) of patients RTS by 6 months after surgery. Pooled proportion analysis from 7 trials with 560 patients demonstrated 93.9% (95% CI, 82.7–99.5%) of patients RTS between 6 and 12 months after surgery. Conclusions: Pooled proportion analysis showed increasingly more patients were able to RTS after THA over the first 1 year after surgery. There remains marked inter and intra-study variations in time for RTS but the pooled analysis shows that over 90% of patients were able to RTS at 6–12 months after THA. These finding will enable more informed discussions between patients and healthcare professionals about time for RTS following THA.
Altmetric Analysis of Skin of Color Articles: A Cross-Sectional Study
Authors: Chang Michelle J. , Lipner Shari R. 
Published: September 2021

Background Publication and dissemination of peer-reviewed articles are essential for delivering up-to-date high-quality care to diverse populations. Online attention and publication trends for skin of color (SOC) articles have not been studied. Objective To investigate SOC article online attention and publication trends. Methods Terms “skin of colo(u)r”, “ethnic skin”, “dark skin”, and “darker skin” were searched on Altmetric. Abstracts were reviewed to exclude non-SOC articles. Altmetric attention score (AAS), media outlets, citations, page views, and journal impact factor were extracted. Results A total of 425 articles, published in 114 journals, were included, with average AAS 13 (0-423), citations 42 (0-1214) and page views 2728 (7-15000). There was a 7.8-fold increase in the number of SOC articles published in the first-half (1993-2006) vs. second-half (2007-2021) of the study period. The number of SOC articles increased by 57%, 2011-2015 to 2016-2020. AAS was significantly correlated with citations ( R = .21), page views ( R = .23) and impact factor ( R = .35) ( P < .05 for all). The top 50 AAS articles had an average AAS 83 (21-423), with 35 (70%) published in the last 5 years (2016-2021) and 47 (94%) published in the second-half of the study period. Top four AAS articles focused on SOC representation in educational resources. Conclusion It is promising that increased numbers of SOC articles have been published in recent years and are garnering more attention, however they are less popular than other dermatology articles. Increased efforts are needed to study and publish on skin diseases in diverse populations to build knowledge and practices that improve patient care.
Demystifying Blue Box Support to Agriculture Under the WTO: Implications for Developing Countries
Authors: Sharma Sachin Kumar , Dobhal Adeet , Agrawal Surabhi , Das Abhijit 
Published: September 2021

Developing members at the WTO face a shrinkage in policy space for supporting their agricultural sector due to the limited room available under the provisions of the Agreement on Agriculture (AoA). Contrastingly, most developed members can provide high levels of product-specific support without breaching their commitments on account of their support entitlements. For some of these members, the so-called ‘Blue Box’ under the AoA, plays a pivotal role in expanding the policy space with respect to domestic support to agricultural products. Though a lot of scholarship has discussed and examined other support provisions under the AoA, the ‘Blue Box’ remains relatively shrouded in mystery. Testimony to this is the fact that although the Blue Box has found use amongst developed members, no developing member, except for China in 2016, has ever used the Blue Box to support their producers. Given the impasse in the Doha Round of negotiations and limited flexibilities available under the AoA, this paper examines the feasibility and compatibility Blue Box measures with developing members’ socio-economic situation. Findings of this paper bring to fore the variations in member practice and the operational flexibilities available in implementing Blue Box programmes to support agriculture. JEL: F13, F14, F17, Q17

Published: September 2021

Introduction: The optimal approach to screening and risk stratification for non-alcoholic fatty liver disease is challenging given disease burden and variable progression. The aim of this study was to assess primary care physician and referring physician practice patterns regarding non-alcoholic fatty liver disease. Methods: An anonymous nationwide survey was administered to primary care physicians, endocrinologists, and cardiologists in a: (1) tertiary academic hospital, (2) community hospital, and (3) the American College of Physicians Insider Panel. Survey domains assessed non-alcoholic fatty liver disease knowledge, recommendations for screening, risk stratification, treatment, and referral patterns. Results: A total of 440 providers completed the survey (35.2% completion rate; N = 82 academic hospital, N = 21 community hospital, N = 337 American College of Physicians). Half were male (51.7%), 78% from internal medicine, with 5% subspecialists. Providers were knowledgeable regarding prevalence and risk factors for non-alcoholic fatty liver disease. 58% would support screening for non-alcoholic fatty liver disease and used liver enzymes to do so. Only 22.5% used serum biomarkers and 23% used transient elastography for risk stratification. Primary reason for referral was advanced fibrosis/cirrhosis. 80% reported barriers to treating non-alcoholic fatty liver disease. There was no consistent diet recommended. Conclusion: In this nationwide survey, we demonstrated that while overall disease knowledge was good, there was an important disconnect between current guidelines and real-world clinical practice. There is also significant heterogeneity in practice patterns for first-line therapy of non-alcoholic fatty liver disease and the majority of provider’s report barriers to treating non-alcoholic fatty liver disease. These findings highlight the potential role for reevaluating screening and risk stratification recommendations in primary care to better align with needs in that setting.

Objective Nasal septal pathologies requiring surgical intervention are common in the population. Additionally, nasal chondrocytes are becoming an important cell source in cartilage tissue engineering strategies for the repair of articular cartilage lesions. These procedures damage the nasal septal cartilage whose healing potential is limited due to its avascular, aneural, and alymphatic nature. Despite the high incidence of various surgical interventions that affect septum cartilage, limited nasal cartilage repair characterizations have been performed to date. Methods To evaluate the healing of the nasal septum cartilage perforation, a septal biopsy was performed in 14 sheep. Two and 6 months later, the tissue formed on the place of perforation was explanted and compared with the native tissue. Tissue morphology, protein and gene expression of explanted tissue was determined using histological, immunohistochemical and real-time quantitative polymerase chain reaction analysis. Results Tissue formed on the defect site, 2 and 6 months after the biopsy was characterized as mostly connective tissue with the presence of fibroblastic cells. This newly formed tissue contained no glycosaminoglycans and collagen type II but was positively stained for collagen type I. Cartilage-specific genes COL2, AGG, and COMP were significantly decreased in 2- and 6-month samples compared with the native nasal cartilage. Levels of COL1, COL4, and CRABP1 genes specific for perichondrium and connective tissue were higher in both test group samples in comparison with native cartilage. Conclusions Newly formed tissue was not cartilage but rather fibrous tissue suggesting the role of perichondrium and mucosa in tissue repair after nasal septum injury.

BACKGROUND The Anatomy and Radiology Contouring (ARC) Bootcamp was a face-to-face (F2F) course designed to ensure radiation oncology residents were equipped with the knowledge and skillset to use radiation therapy techniques properly. The ARC Bootcamp was proven to be a useful educational intervention for improving learners’ knowledge of anatomy and radiology and contouring ability. An online version of the course was created to increase accessibility to the ARC Bootcamp and provide a flexible, self-paced learning environment. This study aimed to describe the instructional design model used to create the online offering and report participants’ motivation to enroll in the course and the online ARC Bootcamp's strengths and improvement areas. METHODS The creation of the online course followed the analysis, design, development, implementation, and evaluation (ADDIE) framework. The course was structured in a linear progression of locked modules consisting of radiology and contouring lectures, anatomy labs, and integrated evaluations. RESULTS The online course launched on the platform Teachable in November 2019, and by January 2021, 140 participants had enrolled in the course, with 27 participants completing all course components. The course had broad geographic participation with learners from 19 different countries. Of the participants enrolled, 34% were female, and most were radiation oncology residents (56%), followed by other programs (24%), such as medical physics residents or medical students. The primary motivator for participants to enroll was to improve their subject knowledge/skill (44%). The most common strength identified by participants was the course's quality (41%), and the most common improvement area was to incorporate more course content (41%). CONCLUSIONS The creation of the online ARC Bootcamp using the ADDIE framework was feasible. The course is accessible to diverse geographic regions and programs and provides a flexible learning environment; however, the course completion rate was low. Participants’ feedback regarding their experiences will inform future offerings of the online course.
