Abstract

Purpose

The purpose of this paper is to reveal the characteristics of strategic behavior during knowledge cooperation in organization and compare the differences in strategy choice between knowledge transferor and knowledge receiver under intricate context consisting of two different objective orientations (organizational and individual) and two different information conditions (perfect and imperfect information) that represent different knowledge application contexts (conventional and available knowledge and intricate and personalized knowledge). Moreover, this paper also wishes to develop a new analysis paradigm of dynamic cooperation game to the micro-interactive mechanism research on individuals’ knowledge sharing in organization.

Design/methodology/approach

Through comparing and referring to previous literatures, and considering the authentic knowledge cooperation practice, this paper first suggested that the behavior characteristics of knowledge sharing between individuals in organization should be observed from the perspective of dynamic cooperation game that would accurately describe the “coopetition” essence of knowledge sharing. Further, an intricate multi-analysis context including two different objective orientations and two different information conditions was constructed. Under this multi-analysis context, the objective functions of knowledge transferor (knowledge output) and knowledge receiver (knowledge returning) were established respectively. Lastly, according to the revenue optimum principle of organizational and individual the strategic choice characteristics were analyzed through the Nash equilibrium to analyze objective functions.

Findings

“Knowledge transaction” motive is classic strategic characteristic of individuals’ knowledge cooperation, and to increase competitiveness of knowledge sharer is a crucial prerequisite for knowledge sharing under any analysis context combination (no matter organizational or individual objective, no matter perfect or imperfect information). Knowledge sharing appears more conservative and stringent under imperfect information condition, and the effort level of knowledge transferring is strategically adjusted according to the value assessment of received knowledge. The institutional constraints and incentives have little effect on the promotion of knowledge sharing under the imperfect information condition where professional knowledge is more intricate, personalized and implicit, because organization members are more sensitive to knowledge competitiveness.

Originality/value

This paper provides a knowledge sharing study with a new analysis paradigm from micro-interactive perspective by aiming at the “coopetition” essence of knowledge cooperation in organization. This analysis paradigm chooses the way of dynamic cooperation game to reveal the strategic characteristics of knowledge sharing among individuals (knowledge transferor and knowledge receiver) and to assess the role of institutional constraints and incentives in promoting the knowledge sharing. At the same time, the establishing of multi-context model with two different perspective dimensions (objective orientation and information condition) make research closer to the authentic circumstance of knowledge cooperation in organization.

Abstract

Purpose

Existing robot-assisted minimally invasive surgery (RMIS) system lacks of force feedback, and it cannot provide the surgeon with interaction forces between the surgical instruments and patient’s tissues. This paper aims to restore force sensation for the RMIS system and evaluate effect of force sensing in a master-slave manner.

Design/methodology/approach

This paper presents a four-DOF surgical instrument with modular joints and six-axis force sensing capability and proposes an incremental position mode master–slave control strategy based on separated position and orientation to reflect motion of the end of master manipulator to the end of surgical instrument. Ex-vivo experiments including tissue palpation and blunt dissection are conducted to verify the effect of force sensing for the surgical instrument. An experiment of trajectory tracking is carried out to test precision of the control strategy.

Findings

Results of trajectory tracking experiment show that this control strategy can precisely reflect the hand motion of the operator, and the results of the ex-vivo experiments including tissue palpation and blunt dissection illustrate that this surgical instrument can measure the six-axis interaction forces successfully for the RMIS.

Originality/value

This paper addresses the important role of force sensing and force feedback in RMIS, clarifies the feasibility to apply this instrument prototype in RMIS for force sensing and provides technical support of force feedback for further clinical application.

The purpose of this paper is to demonstrate a simple fiber sensor for simultaneous measurement of liquid refractive-index (RI) and temperature.

Abstract

Purpose

The purpose of this paper is to demonstrate a simple fiber sensor for simultaneous measurement of liquid refractive-index (RI) and temperature.

Design/methodology/approach

The sensor structure is formed by a long period fiber grating cascaded with a section of thin-core fiber. The long period fiber grating is fabricated on single mode fiber, followed by a section of 20-mm length thin-core fiber which is a modal interferometer.

Findings

Cladding mode interference between long period fiber grating and thin-core fiber modal interferometer is weak in the experimental investigation. Both of these two cladding mode type fiber devices are sensitive to surrounding RI and temperature. So the RI and temperature can be measured simultaneously by monitoring the spectral characteristics of the compound sensor. The sensitivity is calibrated and sensor matrix is provided in the experiment.

Originality/value

This proposed fiber sensor is simple, tough, cost-effective and suitable for discriminate the liquid RI and temperature with high sensitivity.

Abstract

Purpose

The purpose of this paper is to illustrate and examine the effects of ultimate ownership, institutionality and their interactions on capital structure in a unified framework, based on evidence from China.

Design/methodology/approach

Using six years of panel data of Chinese non-financial listed firms between 2004 and 2009, this paper estimates with correlation analysis and multiple regression analysis.

Findings

This paper finds that debt financing facilitates the ultimate owner's expropriation behavior. The separation of control rights and cash flow rights is positively related to capital structure, while cash flow rights negatively affect it. Compared with private ultimate owners, state ultimate owners have less incentive to reap the benefits of expropriation, implying that the separation of control rights and cash flow rights has a smaller effect on the capital structure of state-owned firms. The improvement of institutionality can restrain ultimate owners' expropriation behavior, and regional institutional development is negatively related to capital structure. The separation of control rights and cash flow rights has a smaller positive effect on capital structure in regions with better-developed institutionality.

Originality/value

This paper incorporates ultimate ownership and institutionality into a unified analytical framework of capital structure. It not only enriches related studies on capital structure, but also helps us understand the institutional roots of irrational capital structure behaviors in China. This paper also provides further evidence on ultimate owners' expropriation of minority shareholders through debt financing.

Abstract

Purpose

This paper aims to avoid the precise modeling and controlling problems of rigid structures of hand recovery device, by proposing a hand rehabilitator based on flexible pneumatic actuator with its safety and adaptability.

Design/methodology/approach

The hand rehabilitator is designed based on a flexible pneumatic bending joint. The recovery training program for an injured finger is developed via forearm sEMG (surface electromyogram) sampling, analysis, classification and motion consciousness identification. Four typical movement models of the index finger and middle finger were defined and the corresponding sEMG signals were sampled. After simulation and comparative analysis, autoregressive (AR) model back propagation (BP) network was selected for sEMG analysis and hand recovery planning because of its best recognition performance. A verification test was designed and the results showed that the soft hand rehabilitator and recovery conception are feasible.

Findings

AR model BP network can identify the index finger and middle finger movement intention via an sEMG analysis. The developed flexible pneumatic hand rehabilitator is safe and suitable for finger recovering therapy.

Research limitations/implications

Because of the limitation of experimental samples, the prototype rehabilitator of this work may lack generalizability for other situations. Therefore, for further study and application, systematic structure revising, experiments, data and training are necessary to improve the performance.

Practical implications

The paper includes implications for the development and application of a new style, safe and dexterous hand rehabilitator.

Originality/value

The paper tries a new approach to design a safe, flexible and easily controlled hand rehabilitator.

– This paper aims to explore academics’ perspectives on the quality of appraisal evidence at a Chinese university.

Abstract

Purpose

This paper aims to explore academics’ perspectives on the quality of appraisal evidence at a Chinese university.

Design/methodology/approach

An online survey with both closed items and open-ended questions was distributed among all academics at the university (n = 1,538). A total of 512 responded to the questionnaire. The closed items were initially analysed using EXCEL and SPSS; the open-ended questions were thematically analysed.

Findings

The academics believed that the quality of student survey and peer observation of teaching were affected by subjectivity and the lack of understanding of appraisal. Academics also suggested that appraisals should be contextualised and the approach standardised. The study suggests the need for training that informs and engages relevant stakeholders to ensure the rigour of appraisal.

Originality/value

The study raises the issue of quality assurance regarding appraisal data from the perspective of academics. It is based on the collaborative effort of academics in Australia, China and New Zealand, with the support of the management staff at the case study university. The study informs both appraisers and academics of quality assurance issues in appraisal. It also contributes to the literature, in that it initiates dialogues between communities of practices through collective questioning on the quality and mechanisms of appraisal in tertiary education.

Abstract

Purpose

This paper aims to develop a novel miniature 3-axis force sensor which can detect the interaction forces during tissue palpation in MIS (minimally invasive surgery). MIS offers many significant merits compared with traditional open surgery, the wound to the patients and the postoperative pains are alleviated and reduced dramatically. However, the inherent drawback due to lack of force feedback still exists while conducting some operation procedures. For example, tissue palpation performed easily during open surgery could not be realized in an MIS manner.

Design/methodology/approach

The force sensor is based on the resistive-based sensing method that utilizes strain gauges to measure the strain when the external loads are acting on the tip of the sensor. A novel flexible tripod structure with bending and compression deformations is designed to discriminate the magnitudes and directions of the three orthogonal force components. A linear characteristic matrix is derived to disclose the relationship between the sensitivity and the geometric parameters of the structure, and a straightforward geometric parameterized optimization method considering the sensitivity isotropy is proposed to provide the sensor structure with high sensitivity and adequate stiffness.

Findings

The sensor prototype can perform force measurement with sensing ranges of ± 3.0 N in axial direction and ± 1.5 N in radial direction, and the resolutions are 5 per cent and 1 per cent, respectively. It is concluded that this force sensor is compatible with MIS instruments and the ex-vivo experiment shows that the sensor can be used to perform tissue palpation during MIS procedures.

Originality/value

This paper is intended to address the significant role of force sensing and force feedback during MIS operations, and presents a new application of the resistive-based sensing method in MIS. A tripod structure is designed and a straightforward optimization method considering the sensitivity isotropy of the sensor is proposed to determine geometric parameters suited for the given external loads.
