Teaching the art of functional programming using automated grading (experience report)
Authors: Hameer Aliya , Pientka Brigitte 
Published: July 2019

Online programming platforms have immense potential to improve students' educational experience. They make programming more accessible, as no installation is required; and automatic grading facilities provide students with immediate feedback on their code, allowing them to to fix bugs and address errors in their understanding right away. However, these graders tend to focus heavily on the functional correctness of a solution, neglecting other aspects of students' code and thereby causing students to miss out on a significant amount of valuable feedback.
In this paper, we recount our experience in using the Learn-OCaml online programming platform to teach functional programming in a second-year university course on programming languages and paradigms. Moreover, we explore how to leverage Learn-OCaml's automated grading infrastructure to make it easy to write more expressive graders that give students feedback on properties of their code beyond simple input/output correctness, in order to effectively teach elements of functional programming style. In particular, we describe our extensions to the Learn-OCaml platform that evaluate students on test quality and code style.
By providing these tools and a suite of our own homework problems and associated graders, we aim to promote functional programming education, enhance students' educational experience, and make teaching and learning typed functional programming more accessible to instructors and students alike, in our community and beyond.
Cautious Bully: Reputation, Resolve, and Beijing's Use of Coercion in the South China Sea
Authors: Zhang Ketian 
Published: July 2019

Abstract
Since 1990, China has used coercion in its maritime territorial disputes in the South China Sea, despite adverse implications for its image. China is curiously selective in its timing, targets, and tools of coercion: China rarely employs military coercion, and it does not coerce all countries that pose similar threats. An examination of newly available primary documents and hundreds of hours of interviews with Chinese officials to trace the decisionmaking processes behind China's use and nonuse of coercion reveals a new theory of when, why, and how China employs coercion against other states, especially in the South China Sea. Contrary to conventional wisdom, the findings show that China is a cautious bully that does not use coercion frequently. In addition, when China becomes stronger, it tends to use military coercion less often, choosing instead nonmilitary tools. Moreover, concerns with its reputation for resolve and with economic cost are critical elements of Chinese decisionmaking regarding the costs and benefits of coercing its neighbors. China often coerces one target to deter others—“killing the chicken to scare the monkey.” These findings have important implications for how scholars understand states' coercive strategies and the future of Chinese behavior in the region and beyond.
Factors Associated with Quality of Work-Life Among Faculty of Technical Institutes in Punjab
Authors: Singh Agyapal , Maini Jiwan Jyoti 
Published: July 2019

Purpose: The study aims to find out various factors associated with the quality of work-life (QWL) among faculty working in technical institutes in the state of Punjab, India. Design/Methodology: Data have been collected by judgement sampling—a non-probability sampling technique with a self-designed questionnaire which has been administered to the faculty of various technical institutes (both private and government promoted) situated in the state of Punjab. The data have been analysed with the help of Statistical Package for Social Sciences (SPSS) 20 through Reliability analysis, Kaiser–Meyer–Oklin (KMO) test, Bartlett’s test of sphericity. Thereafter, factor analysis is used to identify the factors associated with the QWL. Findings: Seven factors are identified: management policies, work environment, fair salary and rewards, training and development opportunities, job design and life space, job/social security and grievance handling. Besides these, the factorial validity (convergent and discriminant validity) is also established. Originality: Vast literature is available on the area under study but perhaps none of the studies has been conducted to investigate QWL of faculty in the technical education sector. The implications of these findings will have a significant role in improving the understanding of factors associated with work-life quality of the faculty.

Authors: Cramer Holger , Haller Heidemarie , Klose Petra , Ward Lesley , Chung Vincent CH , Lauche Romy 
Published: July 2019

Objectives: To determine the effectiveness and safety of yoga interventions on disease symptoms, quality of life and function in patients diagnosed with chronic obstructive pulmonary disease (COPD). Data sources: Medline/PubMed, Scopus, and CENTRAL (Cochrane Central Register of Controlled Trials) were searched through 6 June 2019. Review methods: Randomized controlled trials assessing the effects of yoga on quality of life, dyspnea, exercise capacity, and pulmonary function (FEV1) in patients with COPD were included. Safety was defined as secondary outcome. Mean differences (MD) and standardized mean differences (SMD) with 95% confidence intervals (CIs) were computed. Risk of bias was assessed using the Cochrane tool. Results: Eleven randomized controlled trials with a total of 586 patients were included. Meta-analysis revealed evidence for effects of yoga compared to no treatment on quality of life on the COPD Assessment Test (MD = 3.81; 95% CI = 0.97 to 6.65; P = 0.009, I2 = 70%), exercise capacity assessed by the 6-minute walk test (MD = 25.53 m; 95% CI = 12.16 m to 38.90 m; P = 0.001, I2 = 0%), and pulmonary function assessed by FEV1 predicted (MD  = 3.95%; 95% CI = 2.74% to 5.17%; P < 0.001, I2 = 0%). Only the effects on exercise capacity and pulmonary function were robust against methodological bias. Effects were only present in breathing-focused yoga interventions but not in interventions including yoga postures. Adverse events were reported infrequently. Conclusion: This meta-analysis found robust effects of yoga on exercise capacity and pulmonary function in patients with COPD. Yoga, specifically yoga breathing techniques, can be an effective adjunct intervention for patients with COPD. Yoga’s safety needs to be assessed in more depth in future studies.
Which patients do not seek additional medical care after a self-management class for low back pain? An observational cohort
Authors: Garcia Alessandra Narciso , Cook Chad , Rhon Daniel 
Published: July 2019

Objectives: (1) To identify baseline variables associated with patients that sought no additional care during the 12 months following a single self-management education session for low back pain (LBP), and (2) in those who sought care, to determine whether the same variables were associated with low versus high downstream LBP-related healthcare utilization. Design: An observational cohort. Setting: Single large military hospital. Participants: A total of 733 patients with LBP. Intervention: Single self-management education session. Main outcomes: Eleven variables were explored in two distinct logistic regression models: (1) no additional care versus additional care, and (2) low versus high number of additional visits in the additional care group. Results: In the first model, not being on active duty service (odds ratio (OR) = 1.98, 95% confidence interval (CI) = 1.37–2.86), low baseline disability (OR = 1.02, 95% CI = 1.00–1.04), low baseline fear-avoidance related to work (OR = 1.02, 95% CI = 1.00–1.03), and, in the last year, no opioid prescriptions (OR = 1.44, 95% CI = 1.00–2.07), physical therapy (OR = 1.63, 95% CI = 1.00–2.65), or sleep disorder diagnosis (OR = 1.62, 95% CI = 1.05–2.51) significantly increased the odds that patients would not seek any additional care. In the second model, not being on active duty service (OR = 2.18, 95% CI = 1.38–3.46), low baseline disability (OR = 1.04, 95% CI = 1.02–1.06), and no opioid prescriptions in the prior year (OR = 2.19, 95% CI = 1.42–3.37) increased the odds that patients would have less visits (⩽2 visits). Conclusion: Our study found several variables that helped determine whether patients would seek little or no additional care during the 12 months following a self-management education class for LBP.

Authors: Kettlewell Jade , das Nair Roshan , Radford Kate 
Published: July 2019

Objective: This review aimed to determine the effectiveness of personal smart technologies on outcomes in adults with acquired brain injury. Data sources: A systematic literature search was conducted on 30 May 2019. Twelve electronic databases, grey literature databases, PROSPERO, reference list and author citations were searched. Methods: Randomised controlled trials were included if personal smart technology was used to improve independence, goal attainment/function, fatigue or quality of life in adults with acquired brain injury. Data were extracted using a bespoke form and the TIDieR checklist. Studies were graded using the PEDro scale to assess quality of reporting. Meta-analysis was conducted across four studies. Results: Six studies met the inclusion criteria, generating a total of 244 participants. All studies were of high quality (PEDro ⩾ 6). Interventions included personal digital assistant, smartphone app, mobile phone messaging, Neuropage and an iPad. Reporting of intervention tailoring for individual needs was inconsistent. All studies measured goal attainment/function but none measured independence or fatigue. One study ( n = 42) reported a significant increase in memory-specific goal attainment ( p = 0.0001) and retrospective memory function ( p = 0.042) in favour of the intervention. Another study ( n = 8) reported a significant increase in social participation in favour of the intervention ( p = 0.01). However, our meta-analyses found no significant effect of personal smart technology on goal attainment, cognitive or psychological function. Conclusion: At present, there is insufficient evidence to support the clinical benefit of personal smart technologies to improve outcomes in acquired brain injury. Researchers need to conduct more randomised studies to evaluate these interventions and measure their potential effects/harms.

Published: July 2019

Background: Narrative medicine (NM) interventions have positively influenced empathy and burnout to varying degrees in health-care workers. We systematically reviewed the impact of poetry, a form of NM, on empathy and professional burnout. Methods: A comprehensive search of Ovid MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, and Daily, Ovid EMBASE, Ovid PsycINFO, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and Scopus, from inception to September 25, 2018, for articles published in English, was conducted using search terms related to NM, empathy, professional burnout, and health-care personnel. Results: Of the 401 abstracts independently screened for inclusion by 2 reviewers, 2 quantitative, 3 qualitative studies, and 1 research letter were included. One research letter, focusing on the use of poetry, found it to increase empathy as measured by a nonvalidated questionnaire. All other studies used mixed NM interventions: 2 quantitative studies, using validated surveys, showed an increase in empathy and 2 qualitative studies showed limited to a prominent finding of increased empathy. There were no studies that used poetry exclusively to assess impact on professional burnout. One quantitative study, utilizing a validated survey, revealed no overall reduced burnout among residents, although high attendance participants had moderately reduced burnout postintervention, and one qualitative study noted limited reduction in burnout. Conclusion: There is evidence that poetry as part of a NM intervention may increase empathy and limited evidence that it may reduce professional burnout among health-care workers.
Should every candidate for cataract extraction be scheduled to the preoperative clinic? The Rabin Medical Center experience
Authors: Gabbay Itay Elimelech , Gabbay Uri , Goldstein Daniel A , Nahum Yoav 
Published: July 2019

Background: Cataract surgery is one of the most common elective surgeries. We present a novel approach of preoperative triage using community-based ophthalmologist referral letters for scheduling surgery, thus reducing both patient and physician time prior to surgery. Since most patients are not routinely examined in a preoperative clinic, day of surgery cancelations are a possibility. The aim of this study is to evaluate the efficiency of our triage system. Methods: Historical prospective study in which the end point was day-of-surgery cancelation. The main outcome measure of this study was the rate of cancelations which could have been prevented by a preoperative visit. Patients’ records were reviewed for reasons for cancelation and demographics. Results: During the study period, 1030 patients underwent cataract surgery, 171 patients (16.6%) were examined in the preoperative clinic. Forty-five patients (4.4%) were canceled on the day of surgery due to various reasons. The main reason for cancelation (13 cases, 28.9%) was non-availability of operating theater. In 20 cases (1.9% of total patients, 44.4% of cancelations), the cancelations could have been prevented by a preoperative clinic visit. Conclusion: Our results suggests that most cataract patients do not require preoperative visit prior to the day of surgery. The cooperation of community-based ophthalmologists and the availability of senior surgeons in the operating theater allows for the proper implementation of our system. Direct referral to surgery could shorten both costs and time to surgery and provide timely treatment for cataracts in a cost-aware environment.
Assessment of irritability in school-aged children by pediatric, family practice, and psychiatric providers
Authors: Hameed Usman , Dellasega Cheryl , Scandinaro Anna 
Published: July 2019

Background: Irritability, a common behavioral problem for school-aged children, is often first assessed by primary care providers, who manage about a third of mental health conditions in children. Until recent changes in the Diagnostic and Statistical Manual of Mental Disorders (DSM), irritability was often associated with mood disorders, which may have led to increases in bipolar disorder diagnosis and prescription of mood stabilizing medication. Objective: Our aim was to explore differences between the approaches psychiatric and primary care providers use to assess irritability. Methods: A single trained interviewer conducted detailed interviews and collected demographic data from a homogeneous group of physicians that saturated with a sample size of 17 pediatric, family medicine, and psychiatric providers who evaluate and treat school-aged children. Qualitative and quantitative data were collected and analyzed. Results: In general, primary care providers chose to refer children with irritability to mental health specialists when medication management became complex, while the psychiatric providers chose behavior modification and parent education strategies rather than medications. The psychiatric group had a significantly higher caseload mix, prior experience with irritability, and more confidence in their assessment capabilities. There was lack of continuing medical education about irritability in all groups. Conclusion: This preliminary study highlights the importance of collaboration between primary care and subspecialties to promote accurate assessment and subsequent treatment of school-aged children with irritability, who can represent a safety concern for self and others. More research is needed to establish an efficient method of assessing and managing irritability in primary care and better utilization of specialists.
Scoring System to Predict pt2 in Gallbladder Cancer Based on Carcinoembryonic Antigen and Tumor Diameter
Authors: Sakamoto K. , Takai A. , Ueno Y. , Inoue H. , Ogawa K. , Takada Y. 
Published: July 2019

Background and Aims: T2 gallbladder cancer requires lymph node dissection for curative resection, whereas simple cholecystectomy is adequate to treat T1 gallbladder cancer. Hence, this study aimed to develop an accurate scoring system to preoperatively predict pT2 in gallbladder cancer. Material and Methods: We retrospectively assessed data from 57 patients with suspected gallbladder cancer who underwent curative resection between September 2003 and May 2017. Six with apparent invasion of adjacent organs on preoperative images were excluded. We evaluated preoperative computed tomography, magnetic resonance and endoscopic ultrasonographic images, blood biochemistry, and the maximum standard uptake value in fluorodeoxyglucose-positron emission tomography images. We analyzed whether correlations between preoperative findings and the depth of tumor invasion could predict pT2. Results: The pathological diagnosis was gallbladder cancer in 30 (58.8%) patients, of whom 21 (69.9%) had pT2 or worse. Multivariate analyses selected carcinoembryonic antigen and tumor diameter as independent predictors of pT2 or worse (odds ratios = 1.741 and 1.098, respectively; 95% confidence intervals = 1.004–3.020 and 1.008–1.197, respectively). A regression formula was created using carcinoembryonic antigen and tumor diameter to calculate pT2 predictive scores. The area under the receiver operating characteristics curve of the pT2 predictive score was 0.873. Conclusion: We created a scoring system to predict pT2 in gallbladder cancer using carcinoembryonic antigen and tumor diameter. The present findings suggested that carcinoembryonic antigen is important for the preoperative evaluation of gallbladder cancer.

Published: July 2019

Objective The transapical (TA) approach is an alternative access technique for transcatheter aortic valve replacement (TAVR) in patients with symptomatic aortic valve stenosis. The impact of prior coronary artery bypass graft (CABG) surgery and how it affects left ventricular function recovery is not well defined. Methods Patients who had TAVR at a single center between June 2012 and December 2016 were reviewed. High-risk patients who underwent the procedure via a TA approach were divided into 2 groups based on their history of CABG surgery. Postoperative outcomes were compared between groups. CABG/TA-TAVR patients were subdivided into 2 per baseline left ventricular ejection fraction (LVEF) <50%. The changes in LVEF and valve function at follow-up (1 to 12 months) were analyzed using paired t-tests. Results Of 923 cases in total, 183 (19.8%) were performed via a TA approach. The mean ± SD Society of Thoracic Surgeons risk score of TA patients was 10.2 ± 4.6. Forty-nine (27%) had a surgical history of CABG. Overall all-cause mortality rates at 30 days, 1 year, and 2 years were similar for both groups ( P = 0.59, P = 0.64, P = 0.78). Subgrouping of CABG-TAVR patients ( n = 49) identified 24 patients (49%) with LVEF ≥50% vs. 25 (51%) with LVEF <50%. At 1-year follow-up, significant improvements in LVEF (low LVEF group) and valve function for both groups were observed. LVEF ≥50% group (LVEF: ∆: −3%, P = 0.878; aortic valve area [AVA]: ∆: 1.3 cm2, P < 0.001; mean gradient: ∆: −38 mmHg, P < 0.001); LVEF <50% group (LVEF: ∆: 10%, P = 0.01; AVA: ∆: 1.3 cm2, P < 0.001; MG: ∆: −31 mmHg, P < 0.001). Conclusions TA-TAVR can be safely performed with acceptable postoperative outcomes in patients with a history of CABG surgery. In those with reduced EF, significant improvements in LV and valve functions are seen at 1-year follow-up.

Published: July 2019

Background: The health risks associated with poor medication practices in the home suggest that patients would benefit from home-based medication reviews that could detect and resolve these issues. However, remuneration for home visits often excludes ambulatory, nonhomebound patients. A subset of these patients have issues that cannot be adequately identified and resolved during the course of a typical pharmacy-based medication review. Purpose: This study aims to characterize the prevalence and nature of “hidden in the home” medication management issues in nonhomebound patients. Methods: Pharmacists facilitated subject enrollment among patients at 6 community pharmacies in Toronto over a 15-month period, from January 2016 to March 2017. Patients taking 5 or more chronic medications who were ambulatory (able to visit the pharmacy) and scored 3 points or higher on a prescreening questionnaire were invited to participate. Visits included a standard medication review, the identification of drug therapy problems and an assessment of the patient’s medication and organization/storage practices, followed by a medication cabinet cleanup. Results: One hundred patients were recruited, with a mean age of 76.9 years and taking on average 10 chronic medications. Pharmacists identified a total of 275 drug therapy problems (2.75 per patient). The most common issues reported additional therapy required (23.6%), nonadherence (23.3%) and adverse drug reactions (17.8%). For those patients 65 years or older (87%), 32% were found to be using at least 1 medication on the Beers Criteria list, while 6% were using 3 or more. Sulfonylureas, non-steroidal anti-inflammatory drugs and short-acting benzodiazepines were the most commonly implicated drugs. Medications were removed from the homes of 67% of the patients, with expiry of medication being the most common reason for removal (54.2%). The mean duration of a home visit was 49.5 minutes. Conclusion: Pharmacist-directed home medication reviews offer an effective mechanism to address the pharmacotherapy issues of patients taking multiple medications. These findings highlight the frequency of medication management issues in this group and suggest that home medication reviews could serve to minimize inappropriate use of medication and maximize health care cost savings in this unique patient population.
