Politeness as normative, evaluative and discriminatory: the case of verbal hygiene discourses on correct honorifics use in South Korea

This paper uses the concept of “verbal hygiene” (Cameron, Deborah. 1995. Verbal hygiene. Abingdon, UK: Routledge) to analyze metadiscourses in South Korea regarding a recent innovation in the use of subject honorific markers in the service industry. This innovation, commonly referred to as samwul contay ‘inanimate object respect’ involves using honorifics when the grammatical subject of the sentence is an inanimate object, typically the products or services being offered to the customer. Critical discourse analysis was conducted of materials produced by language authorities and mainstream media, as well as layperson-produced blogs and reader comments. The analysis shows that the materials mobilized discourses of ungrammaticality and immorality to delegitimize samwul contay, and stigmatize the sales personnel who used it. By applying the concept of “verbal hygiene” to politeness-related metadiscourses, the current paper advances the perspective that politeness is occasioned through the recursive evaluation of linguistic behavior. Rather than being idiosyncratic, these evaluations appeal to established language norms and moral orders. The way that verbal hygiene discourses promote the language usage of the powerful while stigmatizing the powerless demonstrates that politeness relies inherently on socio-historically imbedded discriminatory practices of placing value on the language usage of certain groups, while delegitimizing that of others.

Quantum (q, h)-Bézier surfaces based on bivariate (q, h)-blossoming

We introduce the (q, h)-blossom of bivariate polynomials, and we define the bivariate (q, h)-Bernstein polynomials and (q, h)-Bézier surfaces on rectangular domains using the tensor product. Using the (q, h)-blossom, we construct recursive evaluation algorithms for (q, h)-Bézier surfaces and we derive a dual functional property, a Marsden identity, and a number of other properties for bivariate (q, h)-Bernstein polynomials and (q, h)-Bézier surfaces. We develop a subdivision algorithm for (q, h)-Bézier surfaces with a geometric rate of convergence. Recursive evaluation algorithms for quantum (q, h)-partial derivatives of bivariate polynomials are also derived.

How Actions Change Liking: The Effect of an Action's Outcome on the Evaluation of the Action's Object

People like positive objects (e.g., fun activities) and dislike negative objects (e.g., boring activities). However, objects usually do not appear in isolation; They are often objects of an action (the boring activities were removed from a class). Using a wide array of stimuli and procedures, 11 experiments (N = 5,574) found that evaluation of objects is biased by the outcome of an action performed on the objects. For example, when participants read that a gene increases the likelihood of possessing the trait kindness (an action with a positive outcome) they evaluated kindness more positively than after reading the gene inhibits the trait (an action with a negative outcome). Conversely, they disliked dishonesty more after reading about genes that increased dishonesty than after reading about genes that decreased dishonesty. The effect was incompatible with logical inference from the information provided. We found evidence that misattribution of the valence of the action’s outcome to the action’s object contributes to this effect. These findings extend knowledge about the factors that lead to evaluative change. Importantly, the results demonstrate a recursive evaluation process: the valence of the outcome of an action on the object determines the evaluation of the object, but the valence of the outcome is already based on a previous evaluation of the object itself.

Visual Servoing for Underwater Vehicle Using Dual-Eyes Evolutionary Real-Time Pose Tracking

[abstFig src='/00280004/12.jpg' width='300' text='ROV with dual-eyes cameras and 3D marker' ] Recently, a number of researches related to underwater vehicle has been conducted worldwide with the huge demand in different applications. In this paper, we propose visual servoing for underwater vehicle using dual-eyes cameras. A new method of pose estimation scheme that is based on 3D model-based recognition is proposed for real-time pose tracking to be applied in Autonomous Underwater Vehicle (AUV). In this method, we use 3D marker as a passive target that is simple but enough rich of information. 1-step Genetic Algorithm (GA) is utilized in searching process of pose in term of optimization, because of its effectiveness, simplicity and promising performance of recursive evaluation, for real-time pose tracking performance. The proposed system is implemented as software implementation and Remotely Operated Vehicle (ROV) is used as a test-bed. In simulated experiment, the ROV recognizes the target, estimates the relative pose of vehicle with respect to the target and controls the vehicle to be regulated in desired pose. PID control concept is adapted for proper regulation function. Finally, the robustness of the proposed system is verified in the case when there is physical disturbance and in the case when the target object is partially occluded. Experiments are conducted in indoor pool. Experimental results show recognition accuracy and regulating performance with errors kept in centimeter level.

Developing a Recursive Evaluation Plan of a Complex Interprofessional Healthcare Education Initiative

Background: A university interprofessional education (IPE) and interprofessional practice (IPP) initiative is a complex undertaking: incorporating multiple system levels (administration, faculty, students, patients), integrating many theoretical perspectives, and coordinating a host of individual IPE research projects. Guidance for evaluating such an IPE initiative is lacking.Methods and Findings: We describe five key challenges to evaluating the effectiveness of such an initiative, and the processes and tools we have developed to meet those challenges. We draw from recent developments in evaluation science to theoretically ground our description. Additionally, we share concrete tools we have developed in the process. By tacking between theoretical and concrete aspects of our efforts, we hope to both provide ideas for other IPE initiatives, as well as provide a basis for future research comparing cases (complex university IPE initiatives).Conclusions: While all complex IPE university initiatives are unique, we suspect that they share many common evaluation challenges. By framing these common practical challenges as common theoretical challenges, we seek to offer a description of our concrete case as well as a basis for future comparison of similar initiatives.

On the Use of Recursive Evaluation of Derivatives and Padé Approximation to Solve the Blasius Problem

The Blasius problem is one of the well-known problems in fluid mechanics in the study of boundary layers. It is described by a third-order ordinary differential equation derived from the Navier-Stokes equation by a similarity transformation. Crocco and Wang independently transformed this third-order problem further into a second-order differential equation. Classical series solutions and their Padé approximants have been computed. These solutions however require extensive algebraic manipulations and significant computational effort. In this paper, we present a computational approach using algorithmic differentiation to obtain these series solutions. Our work produces results superior to those reported previously. Additionally, using increased precision in our calculations, we have been able to extend the usefulness of the method beyond limits where previous methods have failed.
