Abstract

Purpose

Upper-limb joint kinematics are highly complex and the kinematics of rehabilitation exoskeletons fail to reproduce them, resulting in hyperstaticity and human–machine incompatibility. The purpose of this paper is to design and develop a compatible exoskeleton robot (Co-Exos II) to address these problems.

Design/methodology/approach

The configuration synthesis of Co-Exos II is completed using advanced mechanism theory. A compatible configuration is selected and four passive joints are introduced into the connecting interfaces based on optimal configuration principles. A Co-Exos II prototype with nine degrees of freedom (DOFs) is developed and still owns a compact structure and volume. A new approach is presented to compensate the vertical glenohumeral (GH) movements. Co-Exos II and the upper arm are simplified as a guide-bar mechanism at the elevating plane. The theoretical displacements of passive joints are calculated by the kinematic model of the shoulder loop. The compatible experiments are completed to measure the kinematics of passive joints.

Findings

The compatible configuration of the passive joints can effectively reduce the gravity influences of the exoskeleton device and the upper extremities. The passive joints exhibit excellent compensation effect for the GH joint movements by comparing the theoretical and measured results. Passive joints can compensate for most GH movements, especially vertical movements.

Originality/value

Co-Exos II possesses good human–machine compatibility and wearable comfort for the affected upper limbs. The proposed compensation method is convenient to therapists and stroke patients during the rehabilitation trainings.

Abstract

Purpose

The purpose of this paper is to investigate educational functions of the World Heritage Site by examining the case of cultural tourism in a Japanese Buddhist temple.

Design/methodology/approach

Japan accepted the World Heritage Convention in 1992. “Historic Monuments of Ancient Nara” were decided to be listed on the World Cultural Heritage in 1998. It was composed of buildings, monuments and related cultural landscape, including five Buddhist temples and one Shinto shrine. Among them, the Gango-ji, focused in this paper, is one of the oldest Buddhist temples in Japan.

Findings

It has been keeping many cultural properties related to the folk religious practice and providing many activities for the local community. The material culture of folk-belief is now preserved in a building in the temple yard. And there is an exhibition room. The main hall and the exhibition room are the important facilities for social education, where the visitors can watch and touch the real materials. According to the staffs of the temple, the tourists had better stay in the main hall after 1 h study at the exhibition room.

Originality/value

Heritage is a process of the contemporary people engaging in the usage of past as resources. The buildings as the tangible heritage used by the present community are combined with the actions as the intangible heritage of the people who preserve the heritage. The temporal tourists are also permitted to enjoy the process as participants. They can learn many things through their experiences at the heritage site.

Abstract

Purpose

To examine the nature of Chinese business negotiating style in Sino‐Western business negotiations in business‐to‐business markets involving large industrial projects from a social cultural point of view.

Design/methodology/approach

A conceptual approach developed from personal interviews.

Findings

This study reveals that the Chinese negotiator does not possess an absolute negotiating style but rather embraces a mixture of different roles together: “Maoist bureaucrat in learning”, “Confucian gentleman”, and “Sun Tzu‐like strategist”. The Chinese negotiating strategy is essentially a combination of cooperation and competition (termed as the “coop‐comp” negotiation strategy in this study). Trust is the ultimate indicator of Chinese negotiating propensities and role choices.

Research limitations/implications

The focus of this study is on Chinese negotiating style shown in large B2B negotiations with Chinese SOEs.

Originality/value

Differing from most other studies on Chinese negotiating style which tend to depict the Chinese negotiator as either sincere or deceptive, this study points out that there exists an intrinsic paradox in Chinese negotiating style which reflects the Yin Yang thinking. The Chinese negotiator has a cultural capacity to negotiate both sincerely and deceptively and he/she changes coping strategies according to situation and context, all depending on the level of trust between negotiating partners.

Abstract

This chapter enquires whether family migration experience affects the probability of high school graduation of children once unobserved heterogeneity is properly accounted for. Bivariate dynamic random effects probit models for cluster data are estimated to control for the potential endogeneity of education and migration outcomes of elder members of a family in a regression for the education and migration of younger children. Correlation of unobservables across migration and education decisions as well as within groups of individuals such as the family are explicitly modeled. Results show that children from households headed by a migrant are less likely to graduate from high school than children from households headed by a non-migrant. However, as the number of migrants in the family increase, a larger number of migrants in the family is associated with a higher probability of graduation from high school in México. Negative migrant selection in unobservables is detected.

The purpose of this paper is to provide a solution to investigate the deception effects of the radar equipped with decoys.

Abstract

Purpose

The purpose of this paper is to provide a solution to investigate the deception effects of the radar equipped with decoys.

Design/methodology/approach

Since the attacking process of the anti‐radiation missile (ARM) is very complicated, numerical simulations are used here to analyze the effects of the operating parameters and the layout parameters of the radar and the decoys on the survival probabilities.

Findings

The survival probabilities of all the radar and the decoys can be over 99.5 percent when three decoys distribute near the radar in an appropriate way and the decoy level is set to some appropriate values.

Research limitations/implications

The movement model of the ARM is simple and should be improved further.

Practical implications

The numerical results may be applied directly in practice and the dynamic simulation algorithms may be as a reference of the radar‐decoy technique in the future works.

Originality/value

Some coordinate systems are built. Based on it, the models of the radar and decoys against an ARM are introduced, including the fields radiated by the radar and the decoys, the guidance signal and the movement of the ARM. Numerical simulations have been performed here. Some conclusions have been given.

The purpose of this paper is to reexamine the speed and magnitude of exchange rate pass-through (ERPT) to consumer prices in Ghana.

Abstract

Purpose

The purpose of this paper is to reexamine the speed and magnitude of exchange rate pass-through (ERPT) to consumer prices in Ghana.

Design/methodology/approach

The Johansen Maximum Likelihood approach is employed in the estimation of different models of symmetric and asymmetric ERPT. Specifically asymmetric ERPT models with respect to the direction and size of exchange rate changes are estimated.

Findings

Results reveal that even though a depreciation in the nominal effective exchange rate will lead to an increase of consumer prices in the long-run, it is not statistically significant. Evidence also suggests a significant asymmetry with respect to direction and size of exchange rate changes. This indicates that the right ERPT model is an asymmetric model. Specifically ERPT is found to be incomplete but relatively higher in periods of depreciation than in periods of appreciation; that is 53 percent against 3 percent. ERPT is also higher during episodes of large changes (about 51 percent).

Research limitations/implications

It would have been interesting to analyze the impact on consumer prices through changes in import prices. That approach was not adopted due to lack of consistent data on import prices in Ghana.

Practical implications

It is imperative that the monetary authorities critically monitor exchange rate movements in order to be able to take swift policy action so as to counteract any inflationary pressures from the external sector. In particular, much attention should be paid to events and arrangements that could result in large depreciation of the exchange rate.

Originality/value

While previous studies have assumed a symmetric ERPT model for Ghana, this paper is unique in that it investigates the most appropriate model for examining ERPT in Ghana whether symmetric or an asymmetric.

Abstract

Purpose

With the advent of the information age, this paper aims to apply risk analysis theories to study the risk prevention mechanism of information disclosure, thus supporting the green electricity supply.

Design/methodology/approach

This paper conducts a comprehensive evaluation and analysis of the impact of power market transactions, power market operations and effective government supervision, so as to figure out the core risk content of power market information disclosure. Moreover, AHP-entropy method is adopted to weigh different indicators of information disclosure risks for the participants in the electricity market.

Findings

The potential reasons for information disclosure risk in the electricity market include insufficient information disclosure, high cost of obtaining information, inaccurate information disclosure, untimely information disclosure and unfairness of information disclosure.

Originality/value

Some suggestions and implications on risk prevention mechanism of information disclosure in the electricity market are provided, so as to ensure the green electricity supply and promote the electricity market reform in China.

Abstract

Purpose

Many studies have shown that rehabilitation robots are crucial for lower limb dysfunction, but application of many robotics have yet to be seen to actual use in China. This study aimed to improve a lower limb rehabilitation robot by details improving and practical design.

Design/methodology/approach

Structures and control system of a lower limb rehabilitation robot are improved in detail, including joint calculations, comfort analysis and feedback logic creation, and prototype experiments on healthy individuals and patients are conducted in a hospital.

Findings

All participating subjects did not experience any problems. The experiment shows detail improving is reasonable, and feasibility of the robot was confirmed, which has potential for overcoming difficulties and problems in practical application.

Research limitations/implications

Therapeutic effects need to be evaluated in the future. Also, more details should be improved continuously based on the actual demand.

Originality/value

The improved robot could assist the lower limb during standing or walking, which has significance for practical application and patients in China.

Abstract

We examine the construction of “empty categories” – that is, categories created prior to the existence of producers and consumers – and their implications for industry emergence. Drawing on the case of the ji-biru category among Japanese microbreweries, we exemplify how external actors – including governments, the media, consultants, and other entities – frequently create empty categories that are “legitimate yet not legitimated” (Vergne & Wry, 2014). We show how such empty categories generate lower entry barriers, resulting in higher founding rates and significant innovation. We highlight how empty categories impede evolutionary forces by inhibiting shared understandings of what constitutes a legitimate category member.

Abstract

Purpose

Drawing on conservation of resources theory, this study aims to investigate the processes underlying the linkages between job insecurity (JI) and work–family conflict (WFC) from a stress perspective, focusing on the mediating role of subordinates' work withdrawal (WW) and emotional exhaustion (EE). Specifically, the authors tested two distinct mediating mechanisms, namely, WW and EE that have received less attention in testing the JI and WFC linkage. The authors also tested the variable of perceived organizational justice (POJ) to moderate these relationships.

Design/methodology/approach

Survey data collected at Time 1 and Time 2 included 206 professionals from different occupational sectors. The authors study independent variable (i.e. JI), moderator (POJ) and mediator (WW) were measured at Time-1, whereas the other mediator (EE) and outcome (WFC) were tapped by the same respondent at Time-2 with a time interval of one month between them.

Findings

The findings suggest that subordinates’ EE and WW mediate the relationship between JI and WFC. Further, the authors found that EE is a relatively more effective mechanism than WW in explaining how and why JI translates into WFC. The results of the moderated mediation analysis revealed that the indirect effect of JI on WFC is strengthened when POJ is low.

Practical implications

JI has adverse consequences on the employees’ well-being and a cost to the organization in terms of WW. HR and top management should anticipate the negative influence of WW and EE and should focus on nurturing positive work–family climates to help reduce WFCs. Managers should give employees opportunities for participation and foster a climate of fairness in the organization to mitigate the harmful consequences of JI.

Originality/value

This study contributes to the employees’ burnout, counter work behavior and the WFC literature. By introducing EE and WW as underlying mechanisms and identifying POJ as a work contextual variable to explain the JI – WFC relationship, the authors extend the nomological network of JI. The authors respond to the calls by prior researchers as little research has examined how perceived fairness (unfairness) can induce WFC.
