Abstract

Purpose

While a substantial amount of research has been conducted in western societies exploring public attitudes toward police (ATP) among immigrants in recent decades, the question of how recently arrived immigrants view the police in Asian societies has been largely overlooked. This study aims to explore Southeast Asian immigrants' ATP in Taiwan and how assimilation, discrimination, affirmation, procedural justice, bifocal lenses and contact experiences – viewed simultaneously – impact their perceptions.

Design/methodology/approach

Using a combination of convenience and snowball sampling methods, a total of 579 completed survey responses were collected in Taiwan with a response rate of 89%. Structural Equation Modeling (SEM) was used to examine key factors that impact immigrants' attitudes toward the Taiwanese police.

Findings

The findings suggest that procedural justice and assimilation are two robust and direct predictors of immigrants' attitudes toward Taiwanese police. Immigrants from Southeast Asian countries who perceive that they have been treated fairly by Taiwan police tended to report more positive ATP. Likewise, higher levels of assimilation boosted confidence in the police. In addition, both nationality and marital status had a significant impact on perceptions of the police.

Originality/value

This pioneering study examines immigrants' ATP among four groups of Southeast Asians in Taiwan —namely, immigrants from Indonesia, Vietnam, Thailand and the Philippines. The use of SEM strengthens the robustness of the findings derived from this study.

Abstract

Purpose

Building on Lambert’s (2001) work on turnover intent in law enforcement, this study examines how organizational characteristics and job attitudes along with job satisfaction, and organizational commitment affect turnover intent among Taiwanese police officers.

Design/methodology/approach

Data were collected from the New Taipei City Police Department (NTCPD) in the summer of 2012 via stratified random sampling (N = 1,035). Structural equation modeling was employed to examine factors affecting turnover intent.

Findings

Job satisfaction and organizational commitment reduced the risk of turnover, while job stressors and training effectiveness directly increased the risk. Worthy of note, officers with a Central Police University degree and who were married had a lower risk of turnover.

Originality/value

This study applies Lambert’s (2001) turnover intent model in law enforcement agencies developed in the West to a non-western policing setting. The use of SEM assures the robustness of the findings. Some noteworthy contrasts in findings from Western and non-Western settings are presented.

Abstract

Purpose

Drawing upon the police accountability model, the purpose of this paper is to advance the research on public attitudes toward the police (PATP) by examining the effects of reported disorder incidents at the micro level on the two dimensions of PATP.

Design/methodology/approach

This study uses two waves of random sample telephone survey of 2,393 residents in Houston, Texas. The disorder data were provided by the Houston Police Department. Disorder incidents surrounding each respondent’s residence were extracted by using geographic information systems technology. Structural equation modeling was used for the analysis.

Findings

The main findings suggest that while the observational measure of disorder exerts no direct impact on residents’ general attitudes toward the police; it has a significant impact on specific attitudes toward the police measured by using the neighborhoods as the principle geographical context. In addition, documented disorder incidents are found to be a robust predictor of perceptions of disorder in both models.

Originality/value

The measurement of PATP was ambiguous in the research literature and scholarly attention to the observational factors such as reported disorder incidents has been lacking. This study fills the gap of the relevant literature by measuring PATP as a two-dimensional concept and incorporating reported disorder incidents into the analysis.

Abstract

Purpose

The purpose of this research is as follows: DPP-BOH-PVA has been synthesized from 1,1′:3′,1″-terphenyl-5'-boronic acid (DPP-OH) and polyvinyl alcohol (PVA). The afterglow lifetime of DPP-BOH-PVA was studied by changing contents of DPP-OH (1, 2 and 4 Wt.%). These films were characterized with Fourier transform infrared, X-ray diffraction as structural analysis and DSC as thermal analysis. Afterglow lifetimes were evaluated as time-resolved emission decay profile analysis. Fiber films of DPP-BOH-PVA-2-E have been prepared by electrospinning method with the diameter of 5 μm and afterglow life time of 2.1 s (@ 535 nm) under ambient conditions. Stimulus responsive properties with afterglow emission for fiber film were investigated.

Design/methodology/approach

During the synthesis of the polymer, modification was carried out using DPP-OH/PVA with a molar ratio of 1/4, under an alkalinity medium with ammonium hydroxide and with a temperature of 80°C.

Findings

XRD results indicate that DPP-BOH-PVA film had high crystallinity, which is crucial for preparing organic room temperature phosphorescence (RTP) materials.

Research limitations/implications

The reaction mixture must be stirred continuously. Temperature should be controlled to prevent the rapid evaporation of ammonium hydroxide.

Practical implications

This study provides technical information for the synthesis of multidimensional stimulation response RTP micron fiber thin film. The electrospinning technology may also promote the applications of the large areas of RTP films.

Social implications

This resin will be used for the multidimensional stimulation response RTP fiber thin film.

Originality/value

The diameter of fiber film of PP-BOH-PVA-2-E by electrospinning method was in the range of 5 μm, and its afterglow lifetime decayed to be 2.1 s.

Abstract

Purpose

The purpose of this paper is to define the “fast evolving industry” (FEI) and its supply chain management (SCM) challenges. The authors review and structure the literature regarding integration strategies and implementation methods to develop a strategic decision-making framework for SCM in the FEI.

Design/methodology/approach

The authors conduct a review of SCM literature, including supply chain strategy, supply chain integration (SCI), agile and responsive supply chain and SCM for innovative and fast-changing industries. The authors develop a conceptual model and a decision-making framework and use four mini cases to provide support for the model and framework.

Findings

The FEI, characterised by a high level of innovation and differentiation, short products/services lifecycle and high variety, is yet to be fully defined. Inherent uncertainty in FEI supply systems makes SCM in these industries a complex but strategic task for their managers. The framework and the model offered in this study, which employ a core competency concept and provide risk management strategies, offer a strategic tool for managers and scholars in the field to optimise their integration strategies and to operationalise integration decisions.

Originality/value

Little research has been published on transferable and cross-industrial SCM in FEIs. This paper defines the FEI and its resource-related concerns and then offers a conceptual model and a strategic decision-making framework for SCI in FEIs.

Abstract

Purpose

Peer‐to‐peer (P2P) communities have the capability to construct a powerful virtual supercomputer by assembling idle internet cycles. The purpose of this paper is to present the scheduling issues in an unstructured P2P‐based high performance computing (HPC) system to achieve high performance for applications.

Design/methodology/approach

A new application model is proposed for the system, where applications are parallelized in the program level. To address high performance for these applications, the system resources are controlled in a semi‐centralized 3‐layer network, where volunteers form many autonomous unstructured P2P domains. Furthermore, based on such a resource management policy, a job scheduling strategy is adopted, which is collaborated by global and domain scheduling. The global scheduling is responsible for the balance among domains, while the domain scheduling resolve workpiles' execution in a domain.

Findings

Theoretical analysis and a benchmark experiment show that the scheduling provides scalable and enormous computing capability in the P2P‐based HPC system.

Originality/value

The paper shows that scheduling helps P2HP (an unstructured P2P‐based HPC system) provide scalable and enormous computing capability for HPC applications.

Abstract

Purpose

Drawing upon the negativity bias theory, the purpose of this paper is to examine the effects of positive and negative perceptions of police-initiated or citizen-initiated contacts on three distinctive dimensions of public satisfaction with police (PSWP).

Design/methodology/approach

The data were obtained from a random-sample telephone survey of 1,143 residents in Houston in 2012. The OLS regressions were conducted with variables derived from the contact model and neighborhood context model that were often employed in the PSWP research. Particularly, five dichotomous variables were created to tap into the nature and quality of the police-citizen encounters.

Findings

The results confirm the negativity bias theory that “bad is stronger than good,” suggesting that the negative-contact variables have stronger influences on PSWP than the positive-contact variables, net of neighborhood context and demographic background.

Originality/value

This study expands the scope of the investigation on PSWP by exploring the effects of the nature and quality of the police-citizen contacts on the respondents’ sentiments toward the police.

Abstract

Purpose

The purpose of this perspective article is to identify the developmental trajectory of human resource management (HRM) research in the Mainland China as well as the major research gaps to be filled in the future. In particular, the paper focuses on the current challenges as well as the emerging research trends by reviewing the literature in HRM research in the Mainland China.

Design/methodology/approach

The paper takes a geocentric perspective of HRM theory development to analyze the status quo as well as the emerging trends of the future HRM research in the Mainland China.

Findings

HRM research in the Mainland China exhibited an obvious tendency of adopting an etic approach at the early stage of research, but displaying an emerging trend toward an emic approach at a later stage. However, the current HRM research in the Mainland China, including both etic and the emic approaches, falls seriously short of meeting the high-quality standards of the international academic community.

Originality/value

Through analyzing the status quo of HRM research in the Mainland China, the paper identified an emerging trend toward an integration of both etic and emic approaches in which the two approaches constitute a yin-yang duality as a unity-in-opposites toward a geocentric HRM research framework with a holistic, dynamic and duality etic-emic balance.

Abstract

Purpose

The purpose of this paper is to study friction and wear properties of three types of steels against paper-based friction disc, including 65Mn, 20#steel and 30CrAl, so as to obtain the appropriate working conditions for different friction materials in the transmission system.

Design/methodology/approach

Based on actual working conditions, pin-on-disc tests are conducted on a universal material tester. The two evaluation indexes, including average friction coefficient and variation coefficient, are introduced to analyze the different friction properties among three types of steel. Furthermore, the temperature-dependent wear pattern and wear depth are subsequently studied.

Findings

The results show that 65Mn is more suitable for working under heavy load and low velocity, but 30CrAl and 20#steel are suitable for working under light load and high velocity. Moreover, wear primarily occurs on paper-based material and peaks at about 325.

Practical implications

This research of different materials and friction property for friction pairs is helpful to improve the performance and prolong the service life of transmission systems.

Originality/value

Suitable working conditions of different friction materials are obtained, and the correlation between wear and decomposition in high temperature is verified.

Abstract

Purpose

The main purpose of this paper was to investigate Lattice Boltzmann (LB) models for the bulk incompressible flow past immersed bodies and to find the set of boundary conditions (BCs) that can be considered suitable for modeling the borders of the numerical simulation domain in such a way as to avoid any effect of these BC on the flow trail that is formed behind the body.

Design/methodology/approach

Three different models of the Lattice Boltzmann equation (LBE) and six different sets of BCs are tested. In addition to the classical LBE based on the Bhatnagar–Gross–Krook (BGK) single relaxation time collision model, a moments-based model and a model with two relaxation times were investigated.

Findings

The flow pattern and its macroscopic effects on the aerodynamic coefficients appear to be very dependent on the set of BC models used for the borders of the numerical domain. The imposition of pressure at the exit results in pressure perturbations, giving rise to sound waves that propagate back into the simulation domain, producing perturbations on the upwind flow. In the same way, the free-slip BC for the lateral bords appears to affect the trail of vortices behind the body in this range of Reynolds number (Re = 1,000).

Originality/value

The paper investigates incompressible flow past immersed bodies and presents the set of BCs that can be considered suitable for modeling the borders of the numerical simulation domain in such a way as to avoid any effect of these BCs on the flow trail that is formed behind the body.
