The unilateral axle counting sensor is an important railway signal device that detects a train. For efficient and stable detection, the amplitude of induced electromotive force and its changes must be big enough. Therefore, the purpose of this study is to find a way to design and optimize the sensor structure quickly and accurately.
With the help of extensive electromagnetic field calculations, the study puts forward a modified model based on the finite element method, establishes an independent air domain around the sensor, wheel and the railway and adopts a unique grid division method. It offers a design optimization method of the induction coil angles and its spatial location with respect to the excitation coil by using the combination weighting algorithm.
The modified modeling method can greatly reduce the number of finite element mesh and the operation time, and the method can also be applied to other areas. The combination weighting algorithm can optimize the structure of the sensor quickly and accurately.
This study provides a way to design and optimize the structure of the sensor and a theoretical basis for the development. The results can improve and expand the technology of the axle counting sensor.

The purpose of this paper is to present a hypothetical case study which provides an opportunity for students to conduct realistic business analysis applying subject material related to cross‐cultural issues presented in the international business, international management and management courses.
The hypothetical case study requires students to review and analyze cross‐cultural issues related to the appointment of the senior executive for a foreign office of a global business enterprise. A hypothetical Chinese maritime enterprise and its publicly‐traded subsidiary are profiled. Cross‐cultural considerations come into play as the senior executive for two foreign offices must be appointed.
The case reflects refinements based upon its use during the past few years. Students are provided a realistic experiential exercise. Student feedback indicates a heightened sensitivity to cross‐cultural considerations that transcends their assigned textbook readings and traditional testing.
As with any classroom exercise, differences do exist with “real‐world” business practice. Students do not fully appreciate the pressures and tensions experienced by business professionals with respect to recruiting, selecting, appointing and developing a senior executive for a foreign office assignment.
The case study provides an experiential exercise for students to apply theories and concepts learned from the textbook and the instructor's lectures.
The case study offers a complex view of myriad cross‐cultural considerations inherent in an international business firm, providing value to instructors and students as it reinforces discipline theories and concepts in a meaningful way, creating an active learning environment fostering academic excellence.

The purpose of this paper is to examine the effect of perceived land tenure security in China on farmers' decisions to invest in relatively long‐term land quality improvement measures, taking into account the potential endogeneity of tenure security.
Data from a survey held in 2008 and 2010 among 259 households in Minle County, Gansu province, covering the years 2007 and 2009, are used to estimate the factors affecting land levelling investments, irrigation canal investments and perceived land tenure security. The authors use the 2SCML technique and the IVLS method to estimate a selection model and a non‐limited regression model, respectively, and use IVP methods to examine the robustness of the results.
The authors' results indicate that perceived land tenure security significantly affects self‐governed investments but does not affect individual investments in land quality improvements. In particular, the authors find that households that consider land certificates as important for protecting land rights invest significantly more in irrigation canals construction and maintenance. The authors' results further provide evidence that individual investments in land quality improvement contribute to higher perceived land tenure security.
The paper contributes to the available literature on the relationship between land tenure security and land investments by examining the role of perceived (instead of formal) land tenure security and by making a distinction between individual household investments and self‐governed land investments. The authors' results provide an explanation for the phenomenon that land readjustments still take place in some parts of China, but not in others.
