Teaching the unlearnable: a training study of complexyes/noquestions
Authors: AMBRIDGE BEN , ROWLAND CAROLINE F. , GUMMERY ALISON 
Published: April 2020

ABSTRACTA central question in language acquisition is how children master sentence types that they have seldom, if ever, heard. Here we report the findings of a pre-registered, randomised, single-blind intervention study designed to test the prediction that, for one such sentence type, complex questions (e.g.,Is the crocodile who’s hot eating?), children could combine schemas learned, on the basis of the input, for complex noun phrases (the [THING] who’s [PROPERTY]) and simple questions (Is [THING] [ACTION]ing?) to yield a complex-question schema (Is [the [THING] who’s [PROPERTY]] ACTIONing?). Children aged 4;2 to 6;8 (M= 5;6,SD= 7.7 months) were trained on simple questions (e.g.,Is the bird cleaning?) and either (Experimental group,N= 61) complex noun phrases (e.g.,the bird who’s sad) or (Control group,N= 61) matched simple noun phrases (e.g.,the sad bird). In general, the two groups did not differ on their ability to produce novel complex questions at test. However, the Experimental group did show (a) some evidence of generalising a particular complex NP schema (the [THING] who’s [PROPERTY]as opposed tothe [THING] that’s [PROPERTY]) from training to test, (b) a lower rate of auxiliary-doubling errors (e.g.,*Is the crocodile who’s hot is eating?), and (c) a greater ability to produce complex questions on the first test trial. We end by suggesting some different methods – specifically artificial language learning and syntactic priming – that could potentially be used to better test the present account.

AbstractWest Junggar in the southwestern Central Asian Orogenic Belt is a critical area for the study of the Junggar oceanic basin and may also reveal tectonic evolutionary events before the final closure of the Palaeo-Asian Ocean. The sedimentary formations and paragenetic associations of the Upper Carboniferous Chengjisihanshan Formation in southern West Junggar jointly reveal a back-arc basin setting with zircon U–Pb ages of 313–310 Ma for the basaltic rocks. Geochemically, the basaltic rocks are tholeiitic with low SiO2 (47.76–52.06 wt %) and K2O (0.05–0.74 wt %) but high MgO (6.55–7.68 wt %) contents and Mg no. (52.9–58.9) values. They display slightly flat rare earth element patterns with weak positive Eu anomalies, and show enrichments in large ion lithophile elements relative to high field strength elements with negative Nb and Ta anomalies, exhibiting both N-MORB-like and arc-like signatures, similar to the back-arc basin basalt from the Mariana Trough. The high positive zircon εHf(t) and bulk εNd(t) values as well as high initial Pb isotopes, together with relatively high Sm/Yb and slightly low Th/Ta ratios imply a depleted spinel lherzolitic mantle source metasomatized by slab-derived fluids. The field and geochemical data jointly suggest that the volcanic rocks within the Chengjisihanshan Formation were formed in an intra-oceanic back-arc basin above the northwestward subduction of the Junggar oceanic lithosphere in southern West Junggar. The confirmation of the Late Carboniferous back-arc basin basalts, together with other geological observations, indicate that an arc-basin evolutionary system still existed in southern West Junggar at c. 310 Ma, and the Junggar Ocean closed after Late Carboniferous time.
Word learning from context in school-age children: relations with language ability and executive function
Authors: HILL Margaret S. , WAGOVICH Stacy A. 
Published: April 2020

AbstractPurpose: Although school-age children learn most new word meanings from surrounding context, the joint roles of language ability and executive function (EF) in the word learning process remain unclear. This study examined children's acquisition of word meanings from context in relation to oral language ability and three EF skills (working memory, inhibitory control, and cognitive flexibility). Method: Typically developing school-age children completed measures of language and EF, then read and listened to short stories containing unfamiliar target words. A multiple-choice pretest–posttest measure assessed children's target word knowledge gains. Results: Regression analyses showed that language and cognitive flexibility were both related to word knowledge gains; each skill assumed greater importance among children with relative weakness in the other skill. Conclusion: Language ability and cognitive flexibility may each play a direct role in contextual word learning among school-age children, with children naturally relying on one skill if the other is weaker.
Business Travel

Published: April 2020

Abstract. Control over business trips has been considered an important resource for frequent business travelers. Building on past research and conservation of resources theory, this two-wave study among 210 frequent business travelers investigated whether work meaning moderates the relationship between two kinds of control, job control and trip-scheduling control, and two important work outcomes, work satisfaction and perceived task performance. Hierarchical regression analyses showed that when work meaning was lower, trip-scheduling control was negatively related to work satisfaction and perceived task performance 6 months later. However, there were no significant interactions between job control and work meaning on the two outcomes. Findings support the reasoning that trip-scheduling control is of specific importance in the context of business travel and that this particular kind of control is not per se positive but contingent on work meaning and thus the larger context.
A Rare Case of Infected Cervicodorsal Intramedullary Epidermoid Cyst
Authors: Chawla Pawan , Sankhe Milind 
Published: April 2020

Abstract
Introduction  Intramedullary spinal epidermoid cysts have a reported incidence of less than 1% of intramedullary spinal cord tumors; and out of these, intramedullary epidermoid lesions within the cervical spinal cord are even rarer. Here, we present the case of an adult patient with an infected intramedullary epidermoid cyst, identified on magnetic resonance imaging (MRI) at the C7–D1 level that was successfully excised without any worsening of neurological status.
Case Presentation A 23-year-old female patient presented with history of moderate degree intermittent fever followed by gradually progressive right-sided weakness. She had paresthesia below C5 dermatome on the right side. On close inspection of  the back, a tiny sinus opening was noted at the D2 level near the midline. MRI of the spine showed an intramedullary lesion at the C6–D1 level with the tract connecting to the subcutaneous lesion. Somatosensory evoked potential (SSEP) monitoring was done during the surgery with near total excision of the lesion.
Conclusion Even though the location is rare, a differential diagnosis of the epidermoid should always be considered. A tiny dermal sinus opening helped us in proper diagnosis, along with surgical excision, by providing us a direct path to the intramedullary lesion. An early diagnosis and treatment with neurophysiological monitoring helped us in the maximum safe resection of the lesion without developing any new deficit.

Published: April 2020

AbstractHearing healthcare outreach in developing countries is ill defined and inundated with sustainability challenges. One method to facilitate sustainable efforts is by training local personnel on certain aspects of hearing healthcare. The purpose of this descriptive study was to identify the challenges and successes of an audio-technician training program conducted in various regions throughout Guatemala. A collaboration was created between Healing the Children, Centro de Audicion, the University of Washington, and Gallaudet University to create a learning environment for Guatemalan audio-technicians and audiology graduate students. Administration of the audio-technician training component of this program began in 2008 and continues today. Challenges and successes were identified around five themes: (1) audio-technician recruitment and skills upon entering training program; (2) practical and logistical components of clinical training; (3) collaboration and resources for ongoing care; (4) funding for travel, time, and accommodation for personnel involved in training sessions; and (5) cultural differences surrounding our approach to hearing healthcare and training. Approaches to overcome the barriers identified and future directions are discussed.

Published: April 2020

AbstractInternational humanitarian programs are one way for individuals within low-income countries to access hearing health care. Faculty and students from the Idaho State University (ISU) Audiology Program have traveled to several locations within less developed countries over the past 15 years. Most recently, the ISU Audiology Program has partnered with Idaho Condor Humanitarian to provide hearing health care services to Peruvian indigenous people. The humanitarian expedition provides medical, dental, and audiology services to rural villages surrounding Cusco, Peru. Each year the ISU Audiology team gathers data on the hearing health care needs of the Peruvian people and fits donated hearing aids. The ISU Audiology team navigates a variety of barriers associated with limited resources to provide quality hearing health care focused on best practice guidelines for the people of Peru. This article highlights the specific needs of the people served, which the team identified and prioritized, as well as initiated a plan for continuing to develop follow-up care and sustainability.
Ethics and Etiquette in Humanitarian Engagement—101
Authors: Clark Jackie L. 
Published: April 2020

AbstractAs the travel industry continues to grow, so does the creation and proliferation of voluntourism opportunities offered to individuals who want to impact the lives of populations due to adversities or misfortunes of war, weather, or poverty. A more popular form of tourism for individuals to volunteer professional or personal expertise in a chartable manner is often termed “voluntourism.” Unquestionably, there is a lure to volunteer for a short-term experience in exotic lands with the hopes of improving living conditions. This article aims to identify how an individual can move from being a well-meaning voluntourist to an engaged and dedicated humanitarian by following professional ethical principles and etiquette behavior.

Published: April 2020

AbstractOne of the rare complications associated with phototherapy include redistribution of blood flow that can alter cardiac output in infants. The aim of this study was to evaluate the effects of phototherapy on left ejection fraction in infants with jaundice. Twenty-nine infants admitted in Shahid Madani Children Hospital for receiving phototherapy were included in this study. Echocardiography was performed in the participants, immediately before and 24 hours after the treatment. Nineteen infants were reported to have decrease in the stroke volume following the treatment. The mean levels of stroke volume before and after phototherapy were 6.99 ± 2.17 and 6.55 ± 1.85 L/m2, respectively (p = 0.011). Phototherapy can reduce left ejection fraction in newborn infants with hyperbilirubinemia.
Factitious acidosis and severe hypoalbuminemia caused by unsuspected assay interference
Authors: Al Dhaybi Omar , Bakris George L 
Published: April 2020

Abstract
It is relatively common to have some discord between laboratory biomarkers and clinical status. The current practice of medicine relies on imaging and biochemical testing in order to guide decision-making. In the clinical setting, an unsuspected laboratory artifact can have harmful impacts on patients. These circumstances can invariably lead to misdiagnoses, unnecessary testing and inappropriate treatments. We present a case of very low serum bicarbonate (4 mmol/L) in concert with a very low albumin level (0.3 g/dL). It turned out that the lab measurements were erroneous and a lot of harmful interventions could have ensued when dealing with this peculiar case.
Effect of lead on proliferation, oxidative stress and genotoxic damage of 3T3-L1 fibroblasts
Authors: Martini Claudia Noemi , Sosa Fernando Nicolás , Fuchs Julio , Vila María del Carmen 
Published: April 2020

Abstract
Lead (Pb) is an environmental and industrial contaminant that still represents a public health problem. In this paper, we investigated the effect of Pb on proliferation, lipid peroxidation and the number of micronucleated cells in exponentially growing 3T3-L1 fibroblasts, a cell line previously used to evaluate different environmental contaminants.
We found that Pb (10 μM or higher) was able to inhibit proliferation of exponentially growing cells after 24-h treatment, which was evaluated by the MTT assay and cell counting in Neubauer chamber, but cell survival was not affected according to the trypan blue exclusion assay. On the other hand, Pb was able to increase lipid peroxidation and the number of micronucleated cells, which are indicative of oxidative stress and genotoxic damage respectively. We also found that removal of Pb after 24-h treatment allowed cells to recover proliferation. Our results indicate that Pb was able to induce oxidative stress and genotoxicity in this cell line under standardized conditions, which supports the involvement of Pb in similar effects observed in human exposed to this heavy metal. In addition, Pb inhibits proliferation of exponentially growing fibroblasts but cells resume proliferation after removal of this metal, which suggests that it is important to move away Pb-exposed individuals from the source of contamination.
Is it Possible to Treat Insert Dislocation With a Fixed Insert Tibial Component After Primary Oxford Phase 3 Mobile Unicompartmental Knee Arthroplasty?
Authors: Sever Gökhan B. 
Published: April 2020

Background:
The aim of this study was to investigate the clinical and radiologic outcomes of patients who underwent the revision surgery of tibial component replacement using fix-insert in the cases of Oxford phase 3 medial unicompartmental knee arthroplasty with insert dislocation after initial insert replacement.

Materials and Methods:
Nine patients who experienced insert dislocation after insert replacement and who underwent partial replacement revision (tibial component revision) were included in this study. Demographic data and complications of these patients were evaluated. Clinical outcomes were determined through Knee Society Score and Functional Knee Society Score.

Results:
Insert redislocation happened in 11 of 17 patients whose insert was already replaced after initial insert dislocation. Among 11 patients, 2 patients underwent primer and revision total knee replacement revision surgery due to gap inequality and medial collateral ligament deficiency. In the other 9 patients, partial tibal component revision was performed. The mean follow-up time for the patients was 44.4 (21 to 76) months. The mean Knee Society Score/Functional Knee Society Score scores were 80.1 (72 to 95)/78.6 (70 to 90) and 79.5 (72 to 90)/77.5 (68 to 90) at the final follow-up after partial revision and before the insert dislocation, respectively. There was no decline in clinical scores and no revision was required in the mid-term follow-up.

Conclusions:
In this study, we found that there was no worsening in the clinical scores of the patients in the mid-term and no revision was required following the treatment of redislocation through tibial component revision. It was concluded that partial revision treatment with a fixed insert tibial component in the case of insert redislocation does not increase morbidity and could be an ideal treatment option. However, this conclusion should be further supported by multicenter studies along with the high number of cases.

Level of Evidence:
Level IV—retrospective case-control study.
Statistical methods for batch screening of input populations by stage and group in COVID-19 nucleic acid testing
Authors: Yuan Cheng Yuan 
Published: April 2020

AbstractPurposeTo screen for COVID-19 patients in immigration using minimal nucleic acid testing (NAT).MethodsIn the first phase, nasopharyngeal swab samples from the inbound population were numbered and grouped. The samples in the group were mixed together, and a NAT test was performed. When the test result is negative, it means that everyone in the group is not infected and the screening of the group is complete. When the test results were positive, the group moved on to the second stage. In the second stage, all samples in the positive group will be tested individually for NAT.ResultsThe advantages and considerations of the method are discussed. Prevalence in the incoming population was a determinant of the sample size within the group. The lower the incidence, the larger the sample size within the group, the higher the savings in NAT and testing costs.ConclusionThis method has significant efficiency and cost advantages in COVID-19 screening. It can also be used to screen other populations, such as community populations and people at high risk of infection, etc.

AbstractWastewater surveillance may represent a complementary approach to measure the presence and even prevalence of infectious diseases when the capacity for clinical testing is limited. Moreover, aggregate, population-wide data can help inform modeling efforts. We tested wastewater collected at a major urban treatment facility in Massachusetts and found the presence of SARS-CoV-2 at high titers in the period from March 18 - 25 using RT-qPCR. We then confirmed the identity of the PCR product by direct DNA sequencing. Viral titers observed were significantly higher than expected based on clinically confirmed cases in Massachusetts as of March 25. The reason for the discrepancy is not yet clear, and until further experiments are complete, these data do not necessarily indicate that clinical estimates are incorrect. Our approach is scalable and may be useful in modeling the SARS-CoV-2 pandemic and future outbreaks.

Published: April 2020

AbstractBackgroundThere are few reports on the relationship between facial expression formation and mass of the muscle responsible for facial expression. We analyzed the facial expression using facial action coding system (FACS) and examined the muscle mass and characteristics of the facial expression muscles using multi‐detector row computed tomography (MDCT) and magnetic resonance imaging (MRI). Moreover, the relation between these was statistically evaluated.Materials and MethodsTen healthy women in their 40s (43.4 ± 3.0 years, 40‐49) were enrolled. The expressive faces were analyzed by facial expression analysis software based on the FACS. The muscle mass and characteristics of the facial expression muscles were investigated using MDCT/MRI. The correlation between an integrated expression intensity value (IEIV) for FACS of the widest possible grin and muscle mass was analyzed. The mean values between the two categorized groups (G‐1 and G‐2) based on fat infiltration into the muscle were compared.ResultsA positive correlation is found between the IEIV and the muscle mass. The IEIV of G‐1 is significantly larger than the corresponding value of G‐2. Hence, the results indicated that the subjects with high IEIV and expressive face had thicker facial expression muscles and little fat infiltration into the muscles.ConclusionOur objective imaging diagnostic study using FACS, MDCT, and MRI corroborated the anti‐aging medical science about the facial expression muscles related to youthful facial appearance. The results of this research could contribute to the elucidation of the mechanisms involved in the facial aging process and to the development of cosmetology.

Published: April 2020

Efficient planning and management of the workforce resources is one of the most essential requirements for the companies operating in the service sector. For banks, a large number of transactions coming to Central Operations Department from the branches or directly from the customers and their aim is to provide the best operational service with the highest efficiency with the limited workforce resources in the departments. In this study, a real assignment problem was discussed and the problem was considered as Generalized Assignment Problem. For the solution of the problem, related algorithms were listed and examined in the literature survey section. Then, a two-step method is proposed. First step prioritizes the task coming to the system by considering the customer types, service level agreement (SLA) times, cut-off times, task type. In the second step, a multi-objective mathematical model was developed to assign task to employee groups. A preference based optimization method called Linear Physical Programming (LPP) is used to solve the model. Afterward, proposed model was tested on real banking data. For all the tests, GAMS was used as a solver. Results show that proposed model gave better results compared with current situation. With the proposed solution method, the workloads of the profile groups working above their capacity were transferred to other profile groups with idle capacity. Thus, the capacity utilization rates of the profile groups were more balanced and the minimum capacity utilization rate was calculated as 41%.
