Abstract

Purpose

This paper aims to provide a series of new methods for projecting a three-dimensional (3D) object onto a free-form surface. The projection algorithms presented can be divided into three types, namely, orthogonal, perspective and parallel projection.

Design/methodology/approach

For parametric surfaces, the computing strategy of the algorithm is to obtain an approximate solution by using a geometric algorithm, then improve the accuracy of the approximate solution using the Newton–Raphson iteration. For perspective projection and parallel projection on an implicit surface, the strategy replaces Newton–Raphson iteration by multi-segment tracing. The implementation takes two mesh objects as an example of calculating an image projected onto parametric and implicit surfaces. Moreover, a comparison is made for orthogonal projections with Hu’s and Liu’s methods.

Findings

The results show that the new method can solve the 3D objects projection problem in an effective manner. For orthogonal projection, the time taken by the new method is substantially less than that required for Hu’s method. The new method is also more accurate and faster than Liu’s approach, particularly when the 3D object has a large number of points.

Originality/value

The algorithms presented in this paper can be applied in many industrial applications such as computer aided design, computer graphics and computer vision.

Abstract

Purpose

The purpose of this paper is to research comprehensively into the development pattern of the world's 110‐meter hurdles of the coming two years. It aims to provide a detailed reference to the preparation of the 2012 London Olympics.

Design/methodology/approach

The paper uses the GM (2, 1) model, GM (1, 1) model, GM (1, 1) residual fixing model, and the method of recursive compensation by grey numbers of identical dimensions.

Findings

In 2012, the strongest athletes of 110‐meter hurdles are predicted to be: USA athlete Oliver, USA athlete Ash and Cuba athlete Robles. Liu Xiang has the possibility of winning the medal in the 2012 London Olympics.

Practical implications

Because every athlete is an individual that grows up gradually, there are two characteristics in his information: continuity and incompleteness. We can use the grey system methods.

Originality/value

The paper successfully applies the grey prediction to the case study in the field of competitive sports.

Abstract

Purpose

The shared development concept is crucial for the construction of a socialist political economy with Chinese characteristics. The paper aims to discuss this issue.

Design/methodology/approach

This is because shared development constitutes the logic thread of the socialist political economy with Chinese characteristics and the core for the formation and development of its whole system.

Findings

China’s modernization is well underway and is following a unique path with its own characteristics, whereby shared development is undoubtedly one of its core values.

Originality/value

In the new era, the development path under the concept of shared development of socialism with Chinese characteristics must adhere to the all-round development of human beings, promote social equity and justice via development, and embrace inclusive growth, specifically, pro-poor growth.

The purpose of this study is to explore an under‐researched, emotion‐focused influence tactic, strategic emotional display, and its interpersonal and career outcomes.

Abstract

Purpose

The purpose of this study is to explore an under‐researched, emotion‐focused influence tactic, strategic emotional display, and its interpersonal and career outcomes.

Design/methodology/approach

The authors collected data from 258 matched supervisor‐subordinate dyads in a Chinese sample.

Findings

The results indicate that individuals who use positive emotions in social influence tend to enhance their access to network resources and career growth potential, and those who use negative emotions in social influence tend to erode their network resources and hinder career growth potential.

Research limitations/implications

A major limitation of the research is that the authors collected data on both strategic emotional display and network resources from the same source at the same time. Supporting prior research, the results indicate that individuals do use emotional expression as a social influence tactic at work, and that different emotion‐focused influence tactics are associated with different outcomes. The study makes evident the need to integrate the emotion and the social influence literature.

Practical implications

The results of the study indicate that employees may need to develop greater awareness of their own emotions, and cultivate the ability to convey emotional cues to others effectively. It also appears that individuals need to be selective in their use of emotion‐focused influence tactics.

Originality/value

The paper integrates social influence and emotion research, and focuses on a ubiquitous yet overlooked influence tactic, strategic emotional display, and shows evidence that it is associated with interpersonal and career outcomes.

Abstract

Purpose

The purpose of this paper is to clarify the influence of the cathodic polarized potential on the stress corrosion cracking (SCC) susceptibility of X120 steel in a simulated acidic soil solution and the different SCC mechanisms at different cathodic polarized potentials.

Design/methodology/approach

The SCC behaviors of X120 pipe steels at various potentials were investigated in a simulated acidic soil solution by slow strain rate tensile tests, electrochemical impedance spectroscopy and surface analysis techniques.

Findings

The fracture surface of X120 steel stretched in air showed a ductile fracture. Both elongation and tensile strength of X120 steel in the simulated acidic soil solution decreased compared to that obtained in air. A slight cathodic polarization increased the elongation and tensile strength of X120 steel; therefore, the SCC susceptibility was lower at −0.65 VSCE than that at OCP, anodic dissolution dominates the corrosion process. However, a strong cathodic polarization induced hydrogen embrittlement, decreasing elongation and tensile strength, therefore, the SCC susceptibility was highest at −1.1 VSCE, and hydrogen embrittlement became the dominant process.

Originality/value

The paper provides an essential insight into the mechanism of pipeline SCC for X120 steel in acidic soil environments.

Abstract

Purpose

To analyze the impact of the U.S. Supreme Court’s decision in Liu v. SEC, where the Court confronted the issue of whether the SEC can obtain disgorgement in federal district court proceedings.

Design/methodology/approach

This paper provides an overview of the authors’ prior work analyzing courts’ treatment of SEC disgorgement and a summary of the background and opinion in Liu v. SEC. This article then focuses on the practical implications of Liu on SEC disgorgement by considering questions left open by the decision.

Findings

The Court in Liu held that the SEC is authorized to seek disgorgement as “equitable relief” as long as it “does not exceed a wrongdoer’s net profits and is awarded for victims.” But the Court left many unanswered questions, such as whether disgorged funds must always be returned to investors for disgorgement to be a permissible equitable remedy, whether the SEC can obtain joint-and-several disgorgement liability from unrelated co-defendants, what “legitimate expenses” should be deducted in disgorgement calculations, and to what extent the SEC can seek disgorgement in cases when victims are difficult to identify.

Originality/value

Original, practical guidance from experienced lawyers in financial services regulatory and enforcement practices, many of whom have previously worked in the SEC’s Division of Enforcement.

The purpose of this paper is to construct an integrative service model from customer and provider perspectives so that it can be utilized to formulate service business strategies.

Abstract

Purpose

The purpose of this paper is to construct an integrative service model from customer and provider perspectives so that it can be utilized to formulate service business strategies.

Design/methodology/approach

The concepts of the resource‐based view (RBV), customer co‐creation and service modules obtained from a literature review are combined to construct a mathematical model. Based on the model, business strategies are formulated by utilizing existing marketing and service frameworks.

Findings

Innovative services can be generated from the model after combining different core services. To gain competitive advantage in a changing environment, a feedback mechanism should be used to provide dynamism.

Research limitations/implications

An empirical test of the model could be undertaken as a future study to test the validity of the model. Adding more attributes to give the model finer resolution will increase the complexity of the model. Extending the application of the model to firms' internal departments will mean that the relationships between departments have to be reinvestigated.

Practical implications

Obtaining the salient attributes with the heuristics of the 80‐20 rule and the large number principle means optimization of resource utilization under the condition of customer satisfaction.

Originality/value

The model, developed by combining the concepts of RBV, customer co‐creation and service modules, is an innovative tool for the formulation of service business strategies.

Abstract

Purpose

The purpose of this paper is to generalize the traditional risk evaluation methods and to specify a multi-level risk evaluation framework, in order to prepare customized risk evaluation and to enable effectively integrating the elements of risk evaluation.

Design/methodology/approach

A real case study of an electric motor manufacturing company is presented to illustrate the advantages of this new framework compared to the traditional and fuzzy failure mode and effect analysis (FMEA) approaches.

Findings

The essence of the proposed total risk evaluation framework (TREF) is its flexible approach that enables the effective integration of firms’ individual requirements by developing tailor-made organizational risk evaluation.

Originality/value

Increasing product/service complexity has led to increasingly complex yet unique organizational operations; as a result, their risk evaluation is a very challenging task. Distinct structures, characteristics and processes within and between organizations require a flexible yet robust approach of evaluating risks efficiently. Most recent risk evaluation approaches are considered to be inadequate due to the lack of flexibility and an inappropriate structure for addressing the unique organizational demands and contextual factors. To address this challenge effectively, taking a crucial step toward customization of risk evaluation.

Abstract

So far the literature on inverse shape design in aerodynamics is still confined to the single‐point (nominal design point) design and to steady flow. This situation cannot cope with the modern development of internal and external aerodynamics and aerothermoelasticity, especially turbomachinery and aircraft flows. Accordingly, in recent years a new generation of inverse shape design problem has been suggested and investigated theoretically and computationally, consisting mainly of: unsteady inverse and hybrid problems; multipoint inverse and hybrid problems; and inverse problem in aerothermoelasticity. It opens a new area of research in fluid mechanics and aerothermoelasticity. An overview of its status and perspective is given herein, emphasizing the new concepts, theory and methods of solution involved.

Abstract

Purpose

Valence and volume of online reviews are generally considered to influence sales positively. However, existing findings regarding the relative influence of these two components have been inconclusive. This paper aims to explain some of these inconsistencies by examining the moderating role of regulatory focus (both as a chronic disposition and as a situational focus induced by the product category) in the relationship between online review volume/valence and consumers purchase decisions.

Design/methodology/approach

Two studies were conducted. Study 1 used a 2 (Volume: high/ low) * 3 (Valence: high/medium/low) within-subject experimental design. Study 2 analyzed real-world data from Amazon.com. Logistic and panel regression analyses were used to test the research hypotheses.

Findings

The studies confirmed the hypothesized effect of regulatory focus on online review valence and volume effects. Specifically, Study 1 showed that online review valence was more impactful for consumers with a promotion focus than for consumers with a prevention focus. The opposite was true for online review volume effects, where consumers with a prevention focus were influenced more by volume in their decision-making compared to consumers with a promotion focus. Study 2 showed that the pattern of results we found in Study 1 also applied to situational regulatory focus induced by the product category. The effect of review volume on sales rank was stronger for prevention-oriented products, whereas the effect of valence was stronger for promotion-oriented products.

Research limitations/implications

In Study 1, one product category was involved in the study (Digital camera). Involving more different product categories will add reliability to the results of current research. Also, it can offer external validity to current research results. In Study 2, there was no exact measurement for sales, as Amazon.com does not share that kind of information. Instead, Sales Rank was used as a proxy variable. Future research could look into the websites that offer access to the exact sales information.

Practical implications

The current research findings suggest the need for companies to adapt their consumer review management strategy to the regulatory orientation of their target market and products. When a promotion-focused mindset is targeted, strategies for increasing the favorability of product reviews should be used, in contrast, tactics for increasing the quantity of reviews may be more suitable when a prevention-focused mindset is involved.

Originality/value

To the best of the authors' knowledge, this research is the first to investigate the interaction between regulatory focus of consumers and products and online review components.
