Since its creation in 2005, YouTube has become a site for significant community building, as the platform and its affordances encourage active audiences. One creator in the YouTube wellness space is Abbey Sharp, a registered dietitian who reviews ‘What I Eat in a Day’ videos of popular YouTube creators. Sharp’s videos follow the traditional ‘reaction video’ format; she’s positioned as both viewer and consumer, providing commentary on dietary choices and wellness claims. The author investigates Sharp’s role in the spread of wellness misinformation through a life narrative lens as she participates in the wellness community while actively combatting misinformation. Sharp utilises trends and platform affordances to act against health and wellness misinformation. Sharp’s reaction video format creates a collaborative space, where the original creator is taken out of the context of their video and edited into a space where they are critiqued through the lens of a ‘professional’ other. The author argues that Sharp’s health professional status (and reach of over 570,000 subscribers) provides legitimacy to her critique and consequently alters how wellness narratives on YouTube are consumed.

Sharp Corporation, established in 1912, has always tried to identify unique niches that its competitors do not enter, while at the same time continuing to pursue innovation and knowledge creation in those niches. The liquid crystal display (LCD) business is a typical example of Sharp's strategy and innovation. Sharp developed the first successful LCD product – a pocket calculator with a small black and white LCD in 1973 – and since then the company has released a series of unique products with LCDs, including PDAs and camcorders. In 1998, in the face of increasing competition in the traditional cathode-ray tube (CRT) TV market, Katsuhiko Machida, the company's new president and strategic leader, announced his vision of upgrading all bulky CRT televisions sold in the domestic market to flat screen LCD sets by 2005. This vision was bold, since Sharp was the first producer of color CRT TVs and its business was still profitable at the time. However, Machida as strategic leader, predicted tough price competition in the CRT business in the future and began to mobilize Sharp's employees to gain and sustain competitive advantage in the new market.

This paper aims to focus on solving the path optimization problem by modifying the probabilistic roadmap (PRM) technique as it suffers from the selection of the optimal number of nodes and deploy in free space for reliable trajectory planning.

Traditional PRM is modified by developing a decision-making strategy for the selection of optimal nodes w.r.t. the complexity of the environment and deploying the optimal number of nodes outside the closed segment. Subsequently, the generated trajectory is made smoother by implementing the modified Bezier curve technique, which selects an optimal number of control points near the sharp turns for the reliable convergence of the trajectory that reduces the sum of the robot’s turning angles.

The proposed technique is compared with state-of-the-art techniques that show the reduction of computational load by 12.46%, the number of sharp turns by 100%, the number of collisions by 100% and increase the velocity parameter by 19.91%.

The proposed adaptive technique provides a better solution for autonomous navigation of unmanned ground vehicles, transportation, warehouse applications, etc.

It is not difficult to understand why the Sketches would be credited to Sharp. His death four years before the publication of Ricardo's Principles placed him within the period under discussion by Seligman. Sharp possessed an extremely wide range of interests and was a prolific writer on a remarkable variety of topics. By 1809 he was a prominent public figure and had produced more than 40 separate works, several of which had reached second or third editions. He had established a reputation as a controversialist and his oeuvre is certainly consistent with Seligman's generalisation that the ‘greater part of the economic literature’ between 1776 (the year of The Wealth of Nations) and 1817 consisted of ‘pamphlets dealing with current practical problems’ (Seligman, 1903, p. 336). Sharp had published on the conditions in West Africa, the illegality of the press-ganging of sailors, parliamentary reform, colonial law, frankpledge, a popular militia and public charities.

The purpose of this paper is to set up a new framework to enable direct modifications of volume meshes enriched with semantic information associated to multiple partitions. An instance of filleting operator is prototyped under this framework and presented in the paper.

In this paper, a generic mesh modification operator has been designed and a new instance of this operator for filleting finite element (FE) sharp edges of tetrahedral multi-partitioned meshes is also pro-posed. The filleting operator works in two main steps. The outer skin of the tetrahedral mesh is first deformed to round user-specified sharp edges while satisfying constraints relative to the shape of the so-called Virtual Group Boundaries. Then, in the filleting area, the positions of the inner nodes are relaxed to improve the aspect ratio of the mesh elements.

The classical mainstream methodology for product behaviour optimization involves the repetition of four steps: CAD modelling, meshing of CAD models, enrichment of models with FE simulation semantics and FEA. This paper highlights how this methodology could be simplified by two steps: simulation model modification and FEA. The authors set up a new framework to enable direct modifications of volume meshes enriched with semantic information associated to multiple partitions and the corresponding fillet operator is devised.

The proposed framework shows only a paradigm of direct modifications of semantic enriched meshes. It could be further more improved by adding or changing the modules inside. The fillet operator does not take into account the exact radius imposed by user. With this proposed fillet operator the mesh element density may not be enough high to obtain wished smoothness.

This paper fulfils an identified industry need to speed up the product behaviour analysis process by directly modifying the simulation semantic enriched meshes.

In this paper, we study partial identification of the distribution of treatment effects of a binary treatment for ideal randomized experiments, ideal randomized experiments with a known value of a dependence measure, and for data satisfying the selection-on-observables assumption, respectively. For ideal randomized experiments, (i) we propose nonparametric estimators of the sharp bounds on the distribution of treatment effects and construct asymptotically valid confidence sets for the distribution of treatment effects; (ii) we propose bias-corrected estimators of the sharp bounds on the distribution of treatment effects; and (iii) we investigate finite sample performances of the proposed confidence sets and the bias-corrected estimators via simulation.

The purpose of this paper is to determine both analytically and numerically the existence of smooth, cusped and sharp shock wave solutions to a one-dimensional model of microfluidic droplet ensembles, water flow in unsaturated flows, infiltration, etc., as functions of the powers of the convection and diffusion fluxes and upstream boundary condition; to study numerically the evolution of the wave for two different initial conditions; and to assess the accuracy of several finite difference methods for the solution of the degenerate, nonlinear, advection--diffusion equation that governs the model.

The theory of ordinary differential equations and several explicit, finite difference methods that use first- and second-order, accurate upwind, central and compact discretizations for the convection terms are used to determine the analytical solution for steadily propagating waves and the evolution of the wave fronts from hyperbolic tangent and piecewise linear initial conditions to steadily propagating waves, respectively. The amplitude and phase errors of the semi-discrete schemes are determined analytically and the accuracy of the discrete methods is assessed.

For non-zero upstream boundary conditions, it has been found both analytically and numerically that the shock wave is smooth and its steepness increases as the power of the diffusion term is increased and as the upstream boundary value is decreased. For zero upstream boundary conditions, smooth, cusped and sharp shock waves may be encountered depending on the powers of the convection and diffusion terms. For a linear diffusion flux, the shock wave is smooth, whereas, for a quadratic diffusion flux, the wave exhibits a cusped front whose left spatial derivative decreases as the power of the convection term is increased. For higher nonlinear diffusion fluxes, a sharp shock wave is observed. The wave speed decreases as the powers of both the convection and the diffusion terms are increased. The evolution of the solution from hyperbolic tangent and piecewise linear initial conditions shows that the wave back adapts rapidly to its final steady value, whereas the wave front takes much longer, especially for piecewise linear initial conditions, but the steady wave profile and speed are independent of the initial conditions. It is also shown that discretization of the nonlinear diffusion flux plays a more important role in the accuracy of first- and second-order upwind discretizations of the convection term than either a conservative or a non-conservative discretization of the latter. Second-order upwind and compact discretizations of the convection terms are shown to exhibit oscillations at the foot of the wave’s front where the solution is nil but its left spatial derivative is largest. The results obtained with a conservative, centered second--order accurate finite difference method are found to be in good agreement with those of the second-order accurate, central-upwind Kurganov--Tadmor method which is a non-oscillatory high-resolution shock-capturing procedure, but differ greatly from those obtained with a non-conservative, centered, second-order accurate scheme, where the gradients are largest.

A new, one-dimensional model for microfluidic droplet transport, water flow in unsaturated flows, infiltration, etc., that includes high-order convection fluxes and degenerate diffusion, is proposed and studied both analytically and numerically. Its smooth, cusped and sharp shock wave solutions have been determined analytically as functions of the powers of the nonlinear convection and diffusion fluxes and the boundary conditions. These solutions are used to assess the accuracy of several finite difference methods that use different orders of accuracy in space, and different discretizations of the convection and diffusion fluxes, and can be used to assess the accuracy of other numerical procedures for one-dimensional, degenerate, convection--diffusion equations.

To fill this gap, this paper aims to translate the children’s scale of hostility and aggression: reactive/proactive (C-SHARP) into French and then tested its psychometric properties and established the first French standards.

This paper assess the aggressive behavior of 305 children and adolescents with intellectual disability (ID). This paper tested the scale’s factor structure (confirmatory factor analysis), internal consistency and inter-rater reliability.

The results support a factor structure similar to the US version. Factor analysis yielded a five-factor solution, namely, verbal aggression (12 items), bullying (12 items), covert aggression (11 items), hostility (9 items) and physical aggression (8 items). The French-speaking version of the C-SHARP shows good reliability (internal consistency) and good inter-rater reliability. The French version demonstrated encouraging evidence of validity. This paper also established French norms that were similar to US norms. This paper concludes that the French-speaking version of the C-SHARP must benefit from additional psychometric analyzes to confirm its adaptation for research and the clinic.

There is no tool currently available in France for the evaluation of aggressive behavior in children and adolescents with ID. The C-SHARP (Farmer and Aman, 2009) is the only questionnaire that specifically assesses aggression in children and adolescents with ID, its form, frequency and its proactive or reactive qualities. The French version of the C-SHARP could be a useful diagnostic tool to assess aggressive behavior in children and adolescents with ID and to identify and set up appropriate support strategies.

Identification in a regression discontinuity (RD) design hinges on the discontinuity in the probability of treatment when a covariate (assignment variable) exceeds a known threshold. If the assignment variable is measured with error, however, the discontinuity in the relationship between the probability of treatment and the observed mismeasured assignment variable may disappear. Therefore, the presence of measurement error in the assignment variable poses a challenge to treatment effect identification. This chapter provides sufficient conditions to identify the RD treatment effect using the mismeasured assignment variable, the treatment status and the outcome variable. We prove identification separately for discrete and continuous assignment variables and study the properties of various estimation procedures. We illustrate the proposed methods in an empirical application, where we estimate Medicaid takeup and its crowdout effect on private health insurance coverage.

To meet the rapidly increasing demand for medical treatment during the outbreak of COVID-19, Huoshengshan and Leishenshan Hospital are rapidly built (9–12 days) in Wuhan. These two urgent emergency projects are unprecedented. In general, substantial literature suggests that the possibility of shortening a schedule by more than a quarter of its original duration is implausible. By contrast, the two projects had successfully compressed the schedules from months and years to about ten days. This study aims to investigate how this was done and provide references for future projects.

The study uses qualitative case study techniques to analyze the project practices in two urgent emergency projects. Data were gathered through semi-structured interviews and archival research. During interviews, interviewees were asked to describe the project practices adopted to overcome the challenges and freely share their experiences and knowledge.

The results illustrate that a high degree of schedule compression is achievable through tactful crashing, substitution and overlapping applications. The successful practices heavily rely on the high capacity of participants and necessary organization, management and technology innovations, such as three-level matrix organizational structure, reverse design method, site partition, mock-up room first strategies and prefabricated construction technology. For instance, the reverse design method is one of the most significant innovations to project simplification and accelerate and worthy of promotion for future emergency projects.

The empirical findings are significant as they evoke new thinking and direction for addressing the main challenges of sharp schedule compression and provide valuable references for future emergency projects, including selecting high-capacity contractors and replacing the conventional design methods with reverse design.

Substantial studies indicate that the maximum degree of schedule compression is highly unlikely to exceed 25%, but this study suggests that sharp compression is possible. Although with flaws in its beauty (i.e. compressing schedule at the expense of construction cost and quality), it is also a breakthrough. It provides the building block for future research in this fertile and unexplored area.
