Multicenter Initial Guidance on Use of Antivirals for Children With Coronavirus Disease 2019/Severe Acute Respiratory Syndrome Coronavirus 2

Although coronavirus disease 2019 (COVID-19) is mild in nearly all children, a small proportion of pediatric patients develop severe or critical illness. Guidance is therefore needed regarding use of agents with potential activity against severe acute respiratory syndrome coronavirus 2 in pediatrics. A panel of pediatric infectious diseases physicians and pharmacists from 18 geographically diverse North American institutions was convened. Through a series of teleconferences and web-based surveys, a set of guidance statements was developed and refined based on review of best available evidence and expert opinion. Given the typically mild course of pediatric COVID-19, supportive care alone is suggested for the overwhelming majority of cases. The panel suggests a decision-making framework for antiviral therapy that weighs risks and benefits based on disease severity as indicated by respiratory support needs, with consideration on a case-by-case basis of potential pediatric risk factors for disease progression. If an antiviral is used, the panel suggests remdesivir as the preferred agent. Hydroxychloroquine could be considered for patients who are not candidates for remdesivir or when remdesivir is not available. Antivirals should preferably be used as part of a clinical trial if available. Antiviral therapy for COVID-19 is not necessary for the great majority of pediatric patients. For those rare cases of severe or critical disease, this guidance offers an approach for decision-making regarding antivirals, informed by available data. As evidence continues to evolve rapidly, the need for updates to the guidance is anticipated.
Implications of distracted driving on driver behavior in the standing queue of dual left-turn lanes : an empirical study

approved: ______________________________________________________ David S. Hurwitz Driver distraction is a commonly observable phenomenon with a significant effect on the transportation network. Although the negative effects of driver distraction on safety are commonly studied, there has been little effort made to investigate the impacts of distraction on efficiency. This study will examine driver behavior in standing queues at signalized intersection approaches with dual left-turn lanes, and determine what impacts distraction and several other independent variables have on the headways of the first five vehicles. Examining an empirical data set of headway measurements and distraction classifications for over 4000 individual vehicles in Oregon, Utah, and Kansas, linear regression methods will be used to create estimates of the effect of seven in-vehicle distraction classifications (cell phone use, eating or smoking, talking to passengers, manipulating the dashboard other distraction, undistracted, or could not determine). Results show that different distractions increase the median headways of drivers from 5% to 19% when compared to an undistracted driver. The implications of these increased headways on start-up lost time and thus efficiency are then examined.

A Soft Systems Approach to Knowledge Worker Productivity: A Purposeful Activity Model for the Individual

This research attempted to find and define holistic systems that affect the productivity of the knowledge worker (KW), using the soft systems methodology (SSM). It is not enough to look at the management and improvement of knowledge worker productivity (KWP) from the viewpoint of the organization. The viewpoint of the individual KW needs to be considered as well. The KW owns the means of production; they carry their knowledge in their heads and take it with them when changing jobs. This paper proposes a conceptual framework that describes the process in which the KW uses resources to execute actions to create tangible or intangible artifacts with the intention of generating value. It was based on interpretations and inferences made from an extensive literature review using the snowballing method. This paper highlights what implications the lessons learned from the conceptual framework have on managing and improving KWP and delves deeper into four key concepts: value in knowledge work, knowledge, personal resources, and competencies.
A generic framework for continuous energy management at cryogenic air seperation plants

SUMMARY Steel. petrochemicals, metall urgy . explosives, food and many other industries requIre large amounts of a ir products such as oxygen and ni trogen. Cryogeni c air separati on technology is, unli ke other air separation technologies, in a mature stage of its life cycle and currentl y the only practical means avail able for mass-producti on of these air products. Inherent to its operation, cryogeni c air separati on plants are generally energy intensive and power input is considered the main factor on which the ultimate prod uction cost wil l depend. Ex peri ence has shown that relati vely small improvements in energy effic iency on these plants generall y resul t in significant reducti on of production cost.

The effects of children’s Internet use: A Chinese longitudinal study

In this study, we investigate the mediating effects of children’s Internet use on the relationship between family socioeconomic status and their academic achievement, and whether the mediating effects vary across different academic subjects. We used the data from the China Family Panel Studies on the socioeconomic status of children's families, children’s Internet use, and their academic performance. In the 2014 sample, there were 2,686 participants (females=1,272). In 2016, there were 2,330 participants (females=1,069), and in 2018, there were 2,485 participants (females=1,151). The socioeconomic status and the Internet use were measured by a questionnaire. Standardized tests measured the academic performance. Our findings showed that family socioeconomic status was positively related to math performance, but not significantly related to Chinese performance. The results also indicated that Internet use did not significantly mediate the relationship between family socioeconomic status in 2014 and math performance in 2016, while the frequency of Internet use to study in 2016 partly mediated the relationship between family socioeconomic status in 2016 and math performance in 2018. Our findings suggest that Internet use can only mediate the relationship between family socioeconomic status and math performance and the mediating effects become stronger over time. En este estudio, investigamos los efectos mediadores del uso de Internet por parte de los niños en la relación entre el nivel socioeconómico de la familia y su éxito académico y si los efectos mediadores varían entre diferentes disciplinas académicas. Usamos los datos de Estudios de Paneles de las Familias Chinas sobre el nivel socioeconómico de las familias de los niños, el uso de Internet por parte de los niños y su rendimiento académico. Hubo 2.686 participantes en 2014 (mujeres=1.272), 2.330 participantes (mujeres=1.069) en 2016 y 2.485 participantes (mujeres=1.151) en 2018. El estado socioeconómico y el uso de Internet se midieron mediante un cuestionario. Las pruebas estandarizadas midieron el rendimiento académico. Nuestros hallazgos mostraron que el nivel socioeconómico de la familia se relaciona positivamente con el éxito en matemáticas, pero no significativamente con los puntajes chinos. Los resultados indicaron que el uso de Internet no mediaba en la relación entre el estatus socioeconómico familiar en 2014 y el rendimiento matemático en 2016, mientras que la frecuencia de uso de Internet para estudiar en 2016 mediaba en parte la relación entre el estatus socioeconómico familiar en 2016 y el rendimiento matemático en 2018. Nuestros hallazgos proponen que el uso de Internet sólo puede mediar en la relación entre el nivel socioeconómico de la familia y el éxito en matemáticas, y los efectos mediadores se vuelven más fuertes con el paso del tiempo.
Disabled and immigrant, a double minority challenge. A qualitative study about the experiences of immigrant families raising a child with a disability and navigating the Norwegian healthcare system.

Background: Immigrants and their Norwegian-born children make up approximately 18% of the total population in Norway. The legitimacy of the healthcare system is a product of its ability to provide timely and appropriate services to the entire population. While several studies have been conducted on migrants’ utilization of healthcare services, immigrant families are systematically underrepresented in international studies of children with disabilities. This study, by focusing on experiences of immigrant families of children with disabilities who are navigating the Norwegian healthcare system, will generate knowledge of how accessible and tailored the services are from their point of view. Methods: This study took a qualitative approach, using semistructured interviews to explore the experiences of immigrant parents of children with disabilities from non-Western countries. The interviews were transcribed, coded, and analyzed via an inductive thematic analytic approach. Results: The findings show how the “immigrant experience” influenced the way the parents looked at, experienced, and even praised the services. The parents appreciated the follow-up services provided by the pediatric rehabilitation centers, which they experienced as predictable and well-organized. While navigating the services, they experienced several challenges, including the need for information, support, and timely help. They felt exhausted because of the years of struggle in the healthcare system to gain access to the help and services they needed. The feeling of being treated differently from the majority was another challenge they experienced while navigating the services. The findings also show how the parents’ experiences of communication with healthcare providers were influenced not only by their own language and communication skills but also by the healthcare providers’ intercultural communication skills and dominant organizational culture. Conclusions: The parents’ experiences show that there is still a gap between the public ideal of equal healthcare services and the reality of the everyday lives of immigrant families of children with disabilities. By exploring immigrant families’ experiences, this study highlights the importance of mobilization at both the individual and system levels to fill the current gap and provide tailored and accessible services to the entire population. Keywords: Immigrant families, Children with disabilities, Healthcare system.
PAGAN for Character Believability Assessment

—What makes an agent believable? It depends. The concept of ‘believability’ is very subjective with researchers developing different deﬁnitions every time. As a result, assessing it is not straightforward either. Many have adapted the Turing Test in attempts to judge whether or not their agents’ behaviours could fool players into thinking they were controlled by real people. These provided a pool of different studies which explored many games and agents. However, given the many differences between these studies, it is logically impossible to compare between them. This prompted further research with focus on the parameters themselves and even how the design and presented context of a game also affects the outcome. With player experience and game context, areas of interest in affect computing, deeply involved in these assessments, how are these two ﬁelds rarely connected? In this study, we explore this connection by providing a novel way of assessing human-like play using affective computing techniques. It accomplishes this through moment-to-moment assessment of participants’ gameplay, showing that it can provide richer information. In addition, it demonstrates that this new method can not only compliment existing techniques, but also to extract consistent features with linearly predicting factors.
Bond Expectations for Milled Surfaces and Typical Tack Coat Materials Used inVirginia

The ultimate purpose of the program of research of which this study was a part is to identify a test method and acceptance criteria for bonding of hot mix asphalt (HMA) layers. In this study, three tasks were performed to help achieve that purpose: (1) a laboratory comparison of the bond strength of typical tack materials; (2) a field study of the effect of tack on bond strength between a new HMA overlay and a milled surface; and (3) a laboratory investigation of a torque-shear field test to measure bond performance. The findings from these tasks led to several recommendations. The most substantial of the recommendations was that the Virginia Department of Transportation (VDOT) should no longer require the practice of tacking primary horizontal surfaces when placing a new overlay on a milled surface. Further, field engineers and inspectors should remain diligent when it comes to establishing a clean, sound construction platform for any overlay work. Finally, although laboratory tests were inclusive, the torque-shear device should be field tested, with particular emphasis on exposing the test to more realistic conditions. An analysis of the costs associated with conventional tack use found that the material cost per lane-mile is between $572 and $836. A review of the typical “mill and fill” paving activity (maintenance) for the 2008 season found that VDOT would save between $488,000 and $650,000 per year by foregoing conventional tacking on milled horizontal surfaces. If the tacking material is of the non-tracking variety, which is becoming more and more common, the savings could be as much as $950,000 per year.
ServiceQuality,EmployeeEthics,BankCustomerTrust:The Role of Size Moderation and Bank Reputation in Indonesia

Research Objective : This study aimed to determine the effect of service quality and employee ethics on trust and to determine the moderation effect of bank reputation on the relationship between service quality and employee ethics on trust. Furthermore, the researchers also want to know the effect of moderation of bank reputation on the relationship between service quality and employee ethics by including the size of extremely sound bank and sound bank. Research Design / Methodology / Approach : There were 600 bank customers of PT. Bank Mandiri (Persero), Tbk, PT. BCA, Tbk, PT. BRI (Persero), Tbk, PT. BNI (Persero), Tbk in Indonesia as the sample. Data were analyzed by using SEM Lisrel and multigroup analysis by distinguishing banks with the size of extremely sound bank and sound bank. Finding : Service quality and employee ethics have a positive effect on trust. Furthermore, the bank's reputation as a moderating variable strengthens the relationship between service quality and trust and on the contrary weakens the relationship between employee ethics and trust. There is a difference in the effect of the moderating variable of bank size on the relationship between service quality and employee ethics on trust. Practical Implications : The head of bank must provide good service and ethics to customers at the bank. The size and reputation of the bank does not guarantee customer trust in extremely sound bank and sound bank. Originality / Value : The main contribution of this study focuses on exploring the impact of bank reputation moderation on the relationship between service quality and trust, then bank size on the relationship between trust and re-transaction intention of costumers from extremely sound bank and sound bank.
Characteristics of Spray Angle and Discharge Coefficient of Pressure-Swirl Atomizer

A widely distributed spray is an important feature for an atomizer which is required in various applications such as gas cooling, gas turbine combustion, and fluidized bed granulator. Pressure-swirl atomizer is an example of atomizer which provides a wide spray angle through the swirling effect inside the atomizer. One of the important parameters affecting spray angle is atomizer geometrical constant, K. Another important parameter of pressure-swirl atomizer is discharge coefficient, Cd. Discharge coefficient describes the throughput of the liquid flow. An experimental test-rig was constructed to conduct the performance test of the atomizer. Acquired images were analysed using image-processing software. It was found that K has inverse relation with spray angle and direct relation with Cd. Prediction of spray angle and Cd using existing correlations also yields similar trends with the experimental results, but some parameters still need to be considered to perform an accurate prediction.
Stand Structure and Composition 32 Years after Precommercial Thinning Treatments in a Mixed Northern Conifer Stand in Central Maine

The effects of four precommercial thinning (PCT) treatments on an even-aged northern conifer stand in Maine were investigated by examining stand structure and composition 32 years after treatment. Replicated treatments applied in 1976 included: (1) control (no PCT), (2) row thinning (rowthin; 5-ft-wide row removal with 3-ft-wide residual strips), (3) row thinning with crop tree release (rowthinCTR; 5-ft-wide row removal with crop tree release at 8-ft intervals in 3-ft-wide residual strips), and (4) crop tree release (CTR; release of selected crop trees at 88-ft intervals). PCT plots had more large trees and fewer small trees than the control in 2008. There were no other significant differences between the rowthin and control. The rowthinCTR and CTR treatments had lower total and hardwood basal area (BA) and higher merchantable conifer BA than the control. CTR also resulted in more red spruce (Picea rubens [Sarg.]) and less balsam fir (Abies balsamea [L.]) than the other treatments. Although stand structures for rowthinCTR and CTR were similar, the percentage of spruce in CTR was greater. Although the less-intensive rowthinCTR treatment may provide many of the same benefits as CTR, the latter would be the preferred treatment if increasing the spruce component of a stand is an objective. Overall, early thinning treatments were found to have long-term effects on key stand attributes, even more than 30 years after treatment in areas with mixed species composition and moderate site potential.
Computational Assessment of Inlet Turbulence on Boundary Layer Development and Momentum/Thermal Wakes for High Pressure Turbine Nozzle and Blade

A series of systematic computational studies have been conducted for transonic HPT nozzles and blades to evaluate the impact of free stream turbulence on boundary layer growth and downstream wake mixing. Transition modeling is first compared to measurements for an uncooled nozzle. The computational results are compared against measurements of loading, HTC, and wake predictions. The approach is then applied to a cooled trail-edge nozzle. The added complexity of cooling flow injection at the trail-edge showed an increase in deviation between the SST Transition model predictions and wake measurement. By applying a scale resolve model (WALE LES), wake mixing predictions are found within 1% of measurement. Finally, the computational approach is extended to a coupled uncooled nozzle/blade stage analysis. Given the favorable results for an uncooled nozzle using the SST transition model, preliminary assessment of boundary layer impact on HTC and the overall stage loss was made for the nozzle/blade stage design.Copyright © 2014 by ASME

Background: The coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 isspreading all over the world.The main symptoms of COVID-19 include fever, cough,fatigue, and myalgia. However, there are few reports onolfactoryand gustatory dysfunctions in patients with COVID-19.Objective: To investigate the incidence of olfactory and gustatory dysfunctions in patients with confirmed COVID-19 infection, in Wuhan, China.Methods:In this retrospective study,we collected 81 confirmed cases of COVID-19 from the Renmin Hospital of Wuhan University, from February 2020 to March 2020, and analyzed the demographic characteristics, clinical manifestations (including olfactory and gustatory dysfunctions), laboratory findings,and comorbidities.Results: A total of 81 confirmed COVID-19 patients were enrolledin this study (38 males). The most prevalent symptoms include cough, myalgia, and loss of appetite. On admission, 25 (30.9%) of all patients reported either olfactory dysfunction (OD) or gustatory dysfunction (GD), and 7 (8.6%) reported both OD and GD. 13.6% and 25.9% of allpatients reported OD and GD, respectively. OD and GD were not associated with disease severity. Pearson correlation analysisidentified some factors are positively correlated with OD and GD, including headache or dizziness (r = 0.342, P = 0.002), dark urine (r = 0.256, P = 0.021), IgM titer (r = 0.305, P = 0.01), and diabetes (r = 0.275, P = 0.013). In 81.8% of the cases with OD and 28.6% of the cases with GD, the symptomslasted for at least 1 month after discharge.3. 6% of inpatients without OD developed OD after discharge.Conclusion:OD and GDare common in COVID-19.These symptoms appear early during thecourse of disease, and may last for at least 1 month.The incidence of OD and GDisrelated to neurological manifestations, diabetics, and IgM titers.
Lateral stiffness of polycal wire rope isolators – An experimental study

The PWRI is a type of passive isolation system which is commonly used as shock and vibration isolation system especially applied in lightweight equipment and electronic devices. The PWRI can provide isolation in all direction. It can be flexible in any direction and in all three planes which depends on its stiffness. An experimental study of the lateral stiffness of Polycal Wire Rope Isolators (PWRI) is presented in this paper. It also studied effect of variations in height and width of PWRI on its static stiffnesses. Suitable experimental setup was designed and manufactured to meet the test conditions. The results show that their elastic stiffnesses for lateral loading conditions are highly influenced by their geometric dimensions. It is found that their compressive stiffness reduced by 56% for an increment of 25% in their height to width ratio. Therefore, the stiffness of PWRI can be fine-tuned by controlling their dimensions according to the requirements of the application.
