Abstract

Purpose

This paper aims to put forward a kind of new method of intelligent trust engineering metrics for application of mobile ad hoc network (MANET).

Design/methodology/approach

The new method calculates the communication trust by using the number of data packets among the nodes of MANET, predicts intelligently the trust and calculates the comprehensive trust based on the historical trust; then calculates the energy trust based on the residual energy of the nodes of MANET, calculates the direct trust based on the communication trust and energy trust. The new method calculates the recommendation trust based on the recommendation reliability; adopts the adaptive weighting to calculate the integrated direct trust by considering the direct trust with recommendation trust.

Findings

Based on the integrated direct trust and the factor of trust propagation distance, the indirect trust among the nodes of MANET is calculated. The above process can be optimized based on the dynamic machine learning presented in this study. The advantage of the new method is its intelligent ability to discover malicious nodes.

Originality/value

The advantage of the new method is its intelligent ability to discover malicious nodes which can partition the network by falsely reporting other nodes as misbehaving and proceeds to protect the network. The authors have done the experiments based on the tool kits such as NS3, QualNet, OMNET++ and MATLAB. The experimental results show that this study’s approach can effectively avoid the attacks of malicious nodes, and more conformable to the actual engineering application of MANET.

Abstract

Purpose

The communication link in the engineering of Internet of Vehicle (IOV) is more frequent than the communication link in the Mobile ad hoc Network (MANET). Therefore, the highly dynamic network routing reliability problem is a research hotspot to be solved.

Design/methodology/approach

The graph theory is used to model the MANET communication diagram on the highway and propose a new reliable routing method for internet of vehicles based on graph theory.

Findings

The expanded graph theory can help capture the evolution characteristics of the network topology and predetermine the reliable route to promote quality of service (QoS) in the routing process. The program can find the most reliable route from source to the destination from the MANET graph theory.

Originality/value

The good performance of the proposed method is verified and compared with the related algorithms of the literature.

Abstract

Purpose

The purpose of this paper is to investigate the influence of peers’ corporate social responsibility (CSR) on focal firms’ CSR from an integrated perspective. The current study aims to explore whether as peers’ CSR increases focal firms’ CSR would first decrease and then increase.

Design/methodology/approach

This study is based on a sample consisting of Chinese listed manufacturing firms from 2010 to 2016. Hypotheses are tested by generalized least squares method to minimum heterogeneity and autocorrelation concern.

Findings

The results show that focal firms’ CSR would first decrease and then increase with the increase in peers’ CSR. Furthermore, this paper found that corporate visibility would stress more value on CSR differentiation strategy and environmental uncertainty would stress more value on CSR conformity strategy, such that the U-shaped relationship would be more pronounced in high corporate visibility or low environmental uncertainty situation.

Practical implications

The findings may be of interest to the academic researchers and managers. For researchers, it is important to understand how focal firms would practice CSR in response to peers’ CSR, especially through an integrated perspective. For managers, the results show that the best way to invest in CSR activities in response to peers’ CSR follows a U-shaped curve, and corporate visibility and environmental uncertainty are important factors to be considered to make CSR decisions.

Originality/value

This study contributes to the literature by proposing and examining a U-shaped relationship between peers’ CSR and focal firms’ CSR, which stresses the conformity and differentiation value of CSR simultaneously. Besides, to fully map the effects of peers’ CSR and focal firms’ CSR, this paper considers the moderating roles of internal and external contingencies on this non-linear relationship between the peers’ CSR and focal firms’ CSR.

Abstract

Purpose

The purpose of this paper is twofold: to examine generational differences in complaint and post-recovery behaviors after service failures and recoveries, and to investigate the key factors that relate to Generation Y consumers’ responses.

Design/methodology/approach

In a two-stage approach, Study 1 investigates generational differences in the complaint and repurchase behaviors of a vast sample of more than 36,000 customers. Study 2 examines which factors influence Generation Y consumers’ decisions to complain and to repurchase.

Findings

Across four generational cohorts (the Silent Generation, Baby Boomers, Generation X, and Generation Y), consumers in Generation Y are the most likely to complain about service failures and repurchase after a satisfactory service recovery. The service recovery paradox thus is a generational feature. Generation Y’s unique characteristics – being tech savvy, heavily influenced by peers, and untrusting of brands – relate closely to their complaint and repurchase patterns. These prolific users of social media tend to stay with a service provider after experiencing satisfactory recovery but are more inclined to complain.

Originality/value

This study contributes to service management literature by revealing generational differences in customers’ complaint behavior and responses to recovery efforts, while also testing repurchase behavior rather than just behavioral intentions. This study provides valuable insights into the unique factors that influence Generation Y consumers’ complaint and post-recovery responses.

Abstract

Purpose

The purpose of this paper is to illustrate the value of extended time span coverage of state longitudinal education and workforce data system to inform and improve the effectiveness of future high impact expenditure decisions.

Design/methodology/approach

It used an analytical 29-year data file created by the author that links seven already-in-place education and workforce administrative record sources. Relying on the path dependency theory, multi-level mixed-effect logistic and multi-level mixed-effect linear regression models are used to test three hypotheses.

Findings

The findings are consistent with the hypotheses: inclusion of the multiple steps along a post-secondary education pathway and prior job histories are both critical to understanding workforce outcomes mechanisms; it takes time for the employment outcome effect to be evident and strong following education attainment.

Practical implications

The study concludes with research limitations and implications for decision makers to call for retaining and investing in administrative records with extended time span coverage, particularly for the already-in-place historical administrative records.

Originality/value

The paper is one of the first to demonstrate the value of extended time span coverage in a longitudinal state integrated data system through econometric modeling, using longitudinally integrated data linking seven administrative records covering continuously for 29 years. No matter for prior education or employment pathway, it is only through extended time span coverage that employment outcomes can be well measured and the rich nuances interpreting the mechanisms of education return on investment can be revealed.

This study aims to establish a bio-inspired controller for realizing the bounding gait of a quadruped robot system presented in this paper.

Abstract

Purpose

This study aims to establish a bio-inspired controller for realizing the bounding gait of a quadruped robot system presented in this paper.

Design/methodology/approach

The bio-inspired controller is divided into three levels to mimic the biological patterns of animals. First, the high-level sub-controller is equivalent to the cerebellum, which could plan and control the motion of animals. Second, the effect of the middle-level sub-controller corresponds to the central nervous system. The central pattern generators in the spine generate the stable and cyclic signals as the fundamental rhythm for periodic motion of the leg and spine joints. Third, the low-level sub-controller is equal to the end effector, which adopts the simple proportional-derivative (PD) control to realize the specific motion trajectory of the legs and spine.

Findings

Combined with the stability criterion presented previously and the delayed feedback control method, the bounding gait of the cheetah virtual prototype could be actuated and stabilized by the bio-inspired controller. Moreover, the bio-inspired controller is applied to realize the bounding gait of an SQBot, which is a quadruped robot with a spine joint. Meanwhile, the validity and practicability of the bio-inspired controller for the control of quadruped robot have been verified against different forward velocities.

Originality/value

The bio-inspired controller and bionic quadruped robot system are instructive for the designing and actuating of the real quadruped robot.

Abstract

Purpose

Commonly shared logistics services help manufacturing companies to cut down redundant logistics investments while enhance the overall service quality. Such service-sharing mode has been naturally adopted by group companies to form the so-called headquarter-managed centralized distribution center (HQ-CDC). The HQ-CDC manages the common inventories for the group’s subsidiaries and provides shared storage services to the subsidiaries through appropriate sizing, pricing and common replenishment. Apart from seeking a global optimal solution for the whole group, the purpose of this paper is to investigate balanced solutions between the HQ-CDC and the subsidiaries.

Design/methodology/approach

Two decision models are formulated. Integrated model where the group company makes all-in-one decision to determine the space allocation, price setting and the material replenishment on behalf of HQ-CDC and subsidiaries. Bilevel programming model where HQ-CDC and subsidiaries make decisions sequentially to draw a balance between their local objectives. From the perspective of result analysis, the integrated model will develop a managerial benchmark which minimizes the group company’s total cost, while the bilevel programming model could be used to measure the interactive effects between local objectives as well as their final effect on the total objective.

Findings

Through comparing the numerical results of the two models, two major findings are obtained. First, the HQ-CDC’s profit is noticeably improved in the bilevel programming model as compared to the integrated model. However, the improvement of HQ-CDC’s profit triggers the cost increasing of subsidiaries. Second, the analyses of different sizing and pricing policies reveal that the implementation of the leased space leads to a more flexible space utilization in the HQ-CDC and the reduced group company’s total cost especially in face of large demand and high demand fluctuation.

Research limitations/implications

Several classical game-based decision models are to be introduced to examine the more complex relationships between the HQ-CDC and the subsidiaries, such as Nash Game model or Stackelberg Game model, and more complete and meaningful managerial implications may be found through result comparison with the integrated model. The analytical solutions may be developed to achieve more accurate results, but the mathematical models may have to be with easier structure or tighter assumptions.

Practical implications

The group company should take a comprehensive consideration on both cost and profit before choosing the decision framework and the coordination strategy. HQ-CDC prefers a more flexible space usage strategy to avoid idle space and to increase the space utilization. The subsidiaries with high demand uncertainties should burden a part of cost to induce the subsidiaries with steady demands to coordinate. Tanshipments should be encouraged in HQ-CDC to reduce the aggregate inventory level as well as to maintain the customer service level.

Social implications

The proposed decision frameworks and warehousing policies provide guidance for the managers in group companies to choose the proper policy and for the subsidiaries to better coordinate.

Originality/value

This research studies the services sharing on the warehouse sizing, pricing and common replenishment in a HQ-CDC. The interactive decisions between the HQ-CDC and the subsidiaries are formulated in a bilevel programming model and then analyzed under various practical scenarios.

Abstract

Facing the aging workforce but older workers’ vulnerability in the labor market, this chapter empirically explores factors and policy implications to enhance older workers’ entered employment rates (EER) after exiting the national workforce program. After reviewing older workers’ attributes and the unique methods to train them, the chapter examines demographic, socioeconomic, and program attributions to older workers’ EER, controlling for cyclical changes in the labor market. The chapter relies on three sets of models including logistic regression, multi-level mixed-effect regression, and multilevel mixed effect logistic regression models, as well as longitudinal Workforce Investment Act Standardized Record Data and Bureau of Labor Statistics unemployment data. Older dislocated workers and older adults are examined separately. Some Workforce Innovation and Opportunity Act training and related service combinations are identified to contribute to older adults and older dislocated workers’ EER and to inform strategic decision-making about future allocations of funds and policy efforts to serve older workers.

Abstract

Purpose

Previous research has documented the ways that migration contributed to the rise of Hong Kong as a global city by the early 1990s. Much academic attention has been paid to the causes of labor migration and issues related to the adaptation of migrant workers in Hong Kong. Based on a review of such studies, the purpose of this paper is to describe three representative groups of migrant workers in Hong Kong and discuss how research on migrant workers in Hong Kong has provided new insights to the global city literature and to the study of development and migration.

Design/methodology/approach

This paper reviews published works regarding migrant workers in Hong Kong since 1996. Discussion focuses on three representative groups: high-skilled immigrants from developed countries, low-skilled migrant workers from less developed regions and mainland Chinese immigrants.

Findings

Findings suggest that the migration patterns and challenges of the adaptation of migrant workers in Hong Kong correspond largely to the social polarization thesis proposed by global city literature. However, Hong Kong is unique compared to core global cities in the USA and Western Europe due to its special power relationship with mainland China and its colonial history, which have a significant impact on immigrants’ decision to migrate and their post-migration integration.

Originality/value

This review paper provides a better understanding of migration and development, and highlights new factors that contribute to reasons for migration and challenges of integration for migrant workers in the host society.

Abstract

Purpose

This paper aims to examine the occurrence and management of conflict in Chinese organizations, from an emic perspective. The authors provide an in-depth understanding of Chinese working adults’ lived experiences regarding workplace conflicts.

Design/methodology/approach

The study is a qualitative one, consisting of open-ended questionnaires administered to 55 Chinese nationals who worked in governmental, public or international organizations in China. A thematic analysis of the answers was conducted.

Findings

Chinese participants adopted a normative mental model that defined their preferred “way of doing” things. A skillful balance was expected in conflict management that incorporated integrated open communication and strategic silence. Chinese working adults emphasized maturity in the workplace and the recognition of shared goals.

Research limitations/implications

The online questionnaire format may have constrained participants’ responses. Also, the data were collected from various organizational contexts, but there were not enough participants from each type of organization so that comparisons between institutions could be made.

Practical implications

The results could help expatriate populations better prepare their lives abroad in China. Also, the findings could aid organizational or management consultants who work closely with Chinese partners.

Social implications

The findings enhance our understanding of how Chinese working adults deal with workplace conflicts and the circumstances in which conflicts arise in the workplace, which also reflected the social and cultural contexts of the Chinese workplace experience.

Originality/value

This study provides an alternative interpretation of workplace conflicts and their management in China that is anchored in the unique organizational and national cultural context. They constitute the base for future development of culture-based explanations of Chinese organizational conflict behaviors.
