Abstract

Purpose

The purpose of this paper is to examine employees’ personal performance after mobile customer relationship management (m-CRM) use based on an updated model of information system (IS) success. The authors also investigate whether personal performance of employees varies according to the period of m-CRM use.

Design/methodology/approach

Bootstrapping is employed to analyze data collected from a survey of firms using m-CRM. The survey targeted executives and staff members in departments related to the development and application of m-CRM systems.

Findings

The results indicate that some of the factors had no significant effect on employees’ personal performance through employee satisfaction and system use as mediators. Overall, however, the three types of quality had significant effects on employees’ personal performance through employee satisfaction and system use.

Practical implications

The study provides a number of strategies that managers or executives might deploy within organizations to improve employees’ personal performance through the implementation of m-CRM systems. It is of paramount importance for managers or executives to develop m-CRM systems that provide high-quality information and service including sufficient customer-based analysis, up-to-date customer information, barrier-free design and personalized service.

Originality/value

It is the first study to empirically test the role of m-CRM characteristics in predicting employees’ personal performance. This study will not only add contribution to the DeLone and McLean’s theory, but also contribute to the IS literature in IS success. The findings will also provide useful insights for guiding managers or executives in formulating and executing effective strategies to enhance the level of m-CRM use and employee satisfaction which in turn promote personal performance.

Abstract

Purpose

Because of the small size and high integration of capacitive micromachined ultrasonic transducer (CMUT) component, it can be made into large-scale array, but this lead to high hardware complexity, so the purpose of this paper is to use less elements to achieve better imaging results. In this research, an optimized sparse array is studied, which can suppress the side lobe and reduce the imaging artifacts compared with the equispaced sparse array with the same number of elements.

Design/methodology/approach

Genetic algorithm is used to sparse the CMUT linear array, and Kaiser window apodization is added to reduce imaging artifacts, the beam pattern and peak-to-side lobe ratio are calculated, point targets imaging comparisons are performed. Furthermore, a 256-elements CMUT linear array is used to carry out the imaging experiment of embedded mass and forearm blood vessel, and the imaging results are compared quantitatively.

Findings

Through the imaging comparison of embedded mass and forearm blood vessel, the feasibility of optimized sparse array of CMUT is verified, and the purpose of reducing the hardware complexity is achieved.

Originality/value

This research provides a basis for the large-scale CMUT array to reduce the hardware complexity and the amount of calculation. At present, the CMUT array has been used in medical ultrasound imaging and has huge market potential.

Abstract

Purpose

The purpose of this paper is to construct a flux-controlled memcapacitor (MC) emulator without grounded restriction with the binary operation ability. The active first-order low-pass filter (LPF) and high-pass filter (HPF) circuits are constructed by replacing the capacitor with MC.

Design/methodology/approach

The output saturation of the active device is innovatively adopted to realize the binary operation of MC with two memcapacitance values. By applying the direct current control voltage together with the input signal, the memcapacitance can be controlled, and hence, cut-off frequency of the filters can be adjusted without changing the circuit structure.

Findings

Experiments and simulation results show that the new filter has good frequency selectivity. Both LPF and HPF can change the cut-off frequency by changing the positive and negative control voltage. The experimental and simulation results are in good agreement with the theoretical analysis, which proves the feasibility and validity of the emulator and the filters.

Originality/value

These MC emulators are simple and easy to physically fabricate, which have been increasingly used for experiment. It also provide an effective reference for device miniaturization and low power consumption.

Abstract

Purpose

The purpose of this paper is to analyse international political economy (IPE) thought in Korea during its pre-modern and colonial eras.

Design/methodology/approach

It divides these eras into three periods. The first period is the eighteenth century, in which Silhak arose. The second is the mid- and late nineteenth century, a time characterised by conflicts between Wijeong-cheoksa and Gaehwa thoughts. The final period is that of colonial Korea under imperial Japan, and during this time economic nationalist movements were pursued while Marxist theories were also introduced to the country.

Findings

This research shows that IPE thoughts analogous to Western economic liberalism and economic nationalism did emerge endogenously in Korea when its environment was similar to those in which these Western thoughts arose, although in ways that reflected Korea’s peculiar situations of the times. This study also demonstrates that the “economic” thoughts of the Koreans in these periods were shaped largely by their political thoughts.

Originality/value

This research contributes to the building of a more “globalised” intellectual history of classical IPE thought.
