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
Interorganizational power dependence has become an increasingly important factor for small and medium-sized enterprises (SMEs) to improve product innovation. This paper examines the role of power dependence in SMEs' product innovation trade-offs between exploration and exploitation. The article further studies the mediating effect of supply chain adaptability and the moderating effect of knowledge acquisition on the relationship between power dependence and product innovation.
Design/methodology/approach
The study proposes a model to verify the impact of power dependence on SMEs' product innovation trade-offs based on social network theory. Two conceptually independent constructs, “availability of alternatives (ALTRN)” and “restraint in the use of power (RSPTW),” are used to evaluate the power dependence. The model also analyzed how these effects are mediated by supply chain adaptability and moderated by knowledge acquisition. The authors test these relationships using data collected from 224 SMEs in China.
Findings
The empirical analysis shows that ALTRN has a more substantial effect on exploration for product innovation, while RSTPW has a more significant impact on exploitation for product innovation. Moreover, empirical data indicate a partial mediating effect by supply chain adaptability between power dependence and product innovation of SMEs. The results also show that knowledge acquisition positively moderates the relationship between ALTRN/RSTPW, supply chain adaptability and product innovation.
Originality/value
Overall, the findings of the study advance the understanding of the roles of power dependence in product innovation for SMEs. In addition, the research also uncovers the impact mechanisms of existing theoretical frameworks and extends the boundaries of the theory.

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.

Abstract
Purpose
Karl Marx's social capital reproduction theory is his significant contribution to economics. The purpose of this paper is to review the contributions of the exploration of Chinese economists (especially Professor Liu Guoguang) in the concretization of Marx’s social capital reproduction theory combined with socialist construction since 1949.
Design/methodology/approach
During this process, Professor Liu Guoguang, a famous Chinese Marxist economist, has made an outstanding contribution by creating a Marxist social capital reproduction model with Chinese characteristics and a distinctive Marxist economic growth model. Professor Liu's exploration is still of crucial practical significance to building a socialist market economy today.
Findings
The process and achievements in the sinicization exploration of Marx's social capital reproduction theory were reviewed. With the reform and opening up, fundamental changes have occurred in China's economic system – the centralized planned economic system has been transformed into a socialist market economic system.
Originality/value
The planned management of the national economy is replaced by a macro-regulation system characterized by gross control gradually, and the concepts of agriculture, light industry, and heavy industry, and their intercorrelation are no longer applied in theory and policy. However, the sinicization exploration of Marx's social capital reproduction theory in the older generation of Marxist economists represented by Liu is not only of historical significance but also of important practical significance.

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.
