Abstract

Purpose

This paper aims to provide a 3D finite element (FE) model for dynamic simulation of cutterhead and soil interaction in slurry shield tunneling.

Design/methodology/approach

Dynamic numerical simulation of excavation process is realized by combined use of submodeling method and arbitrary Lagrangian Eulerian (ALE) approach. The model size reduction, soil mesh refinement and stress state initialization are fulfilled by submodeling. The large soil deformations, failures and flows are handled by ALE approach. Computation time is reduced by parallel domain decomposition with recursive coordinate bisection method. Validation of the proposed approach is achieved by comparing the numerical results with monitored data from the model test for Yangtze River tunneling project.

Findings

The proposed approach proves to be an effective technique to simulate the cutterhead and soil interaction dynamically in tunnel excavation. Comparative study on the effect of mesh density indicates the requirement of relative mesh refinement. Exploration of the parallel computing performance points out the best decomposed domain for the simulation. Parametric study on the effect of rotary speed and investigation on soil properties presents the significant factors for torque.

Practical implications

The proposed numerical model can help in the development process of reduced‐scale model test, as well as design and selection of slurry shield machines.

Originality/value

The originality comes from the need to evaluate the excavation performance of slurry shield machine in tunneling project. This contribution provides a 3D numerical approach, which takes into account the stress state in soil and dynamic contact effects between soil and cutterhead. In this work, large deformation in soil is handled. Besides, soil failures and flows are captured.

Abstract

Purpose

This paper aims to unveil the business‐government‐society relationship in China, as compared with that in the USA.

Design/methodology/approach

Three cases – the Chinese milk scandal, the beef recall, and the peanut butter scandal in the USA – are presented and contrasted.

Findings

The business‐society‐government relationship in China sets itself apart from that in the USA, largely due to its one‐party political system and the Confucian tradition. The relative lack of independent watchdogs and advocacy groups and the relative lack of independence of the media make it more difficult for irresponsible behavior by powerful corporations to be exposed in China. Further, paternal local governments can sometimes play an enabling role to companies engaged in irresponsible behavior under their protective wings.

Research limitations/implications

With little extant research in the area of corporate social responsibility in the Chinese context, future research can build on this research and further test the relationship with quantitative data.

Practical implications

The research provides insights into the context of business operations in China and thus has significant practical relevance.

Originality/value

The paper is the first to explore the business‐government‐society relationship in China.

Abstract

Purpose

Aiming at improving the mechanical efficiency, the applicability and the working life of high water-based hydraulic motor (HWBHM) under working conditions at low speed and high pressure, the friction performance of different matching materials for piston slipper – crankshaft pair with high water-based hydraulic fluid (HWBHF) under working conditions at low speed and high pressure – were studied.

Design/methodology/approach

The friction experiments for different materials (316L, 316L with surface coating OVINO – tetrahedral amorphous carbon [TAC; 316L-TAC] – 316L with surface coating OVINO-graphite intercalated compound [GIC; 316L-GIC] and polyetheretherketone [PEEK] reinforced with 30 per cent carbon fiber [PEEK-30CF]) under HWBHF lubrication were implemented on a pin-disk friction abrasion machine to determine the variations of coefficient of friction (CoF) and wear rate for each matching materials. In addition, the roughness and the morphology of worn surface of different matching materials were quantitatively characterized.

Findings

The study revealed that material combinations have different friction performances. Test results showed that the abrasion of matching type stainless steel (SS) and SS is rather serious, and the method of surface coating could improve the friction performance of SS when friction with other materials. For matching type of SS with surface treatment (SS-ST) and SS-ST, 316L-GIC and 316L-GIC have relatively stable CoF, and the wear rate was smaller than other matching materials, while 316L-TAC and 316L-TAC has the smaller CoF than that of 316L-GIC. Matching materials 316L-GIC with PEEK-30CF of matching type SS-ST and PEEK-30CF has more stable COF and better wear resistance than those of other matching materials.

Originality/value

This research has laid a foundation for the improvement of service life and working efficiency of friction pair in HWBHM under working conditions at low speed and high pressure.

Abstract

Purpose

Luxury brands struggle to communicate their sustainability commitments to consumers due to the perceived incongruence between “luxury” and “sustainability”. This study aims to provide luxury brands with insights on how to engage consumers with different social value orientations (SVOs) to make sustainable luxury purchases in a compatible manner. It investigates the relationships between personal values (symbolism/universalism), SVOs (pro-self/prosocial orientation) and behavioral intentions toward sustainable luxury brands. It further explores whether these relationships may differ when consumers view themselves as individuals (salient personal identity is activated) versus group members (salient social identity is activated).

Design/methodology/approach

Study 1 (N = 419) used an online experiment in which participants were randomly assigned to either salient personal or social identity conditions to test the proposed model. Study 2 (N = 438) used a fictional brand to further validate the findings. Hypotheses were tested using covariance-based structural equation modeling (CB-SEM) and multi-group SEM.

Findings

Results indicate that prosocial orientation significantly increases consumers’ behavioral intentions toward sustainable luxury brands. Interestingly, pro-self-orientation can also drive intentions to support sustainable luxury brands when consumers’ personal identity is salient. Salient social identity can further strengthen the relationship between prosocial orientation and sustainable luxury behavioral intentions.

Originality/value

This study presents a novel, inclusive definition of sustainable luxury brands and adds theoretical rigor to the SVO framework by revealing the moderating role of salient identities, contributing to the body of knowledge in luxury brand research.

Abstract

Purpose

Merely being known as a highly ethical or strong performer cannot shield a company from every kind of crisis. From product failures to environmental and social issues, a brand’s ability to manage crises and rapidly regain consumer trust is essential. This study aims to explore whether consumer perceptions of a brands’ prior commitments to two different areas of corporate responsibility (social and product responsibility) alleviate the postcrisis attribution of accountability and further build brand resilience, examining differences between two types of crisis situations – values versus performance crises.

Design/methodology/approach

A scenario-based online survey on product versus ethical labor issues was conducted. The data were collected from a highly valid, nationwide sample set of more than a thousand US consumers. Multigroup structural equation modeling was used as the primary data analysis method.

Findings

A brand’s precrisis commitment to social responsibility was found to decrease attribution of accountability across both types of crises. It also strengthened brand resilience, but this effect was more prevalent in a performance than a values crisis. The effects of precrisis commitment to product responsibility on brand resilience were minimal or insignificant across crisis types.

Originality/value

Previous research underexplores which types of corporate responsibility commitments provide a firm with a better protection against crises. This study significantly advances the knowledge regarding the type of commitments that can substantially increase brand resilience, which supports the rationale of making stronger commitments to social responsibility than to product responsibility. Practical insights are provided into how investments in corporate social responsibility help alleviate consumers’ negative perceptions during the outbreak of a brand crisis and build more brand muscle that enables resilience against future crises.

Abstract

Purpose

Given the unclear lines between traditional and newly emerged luxury, this research aims to explore which luxury consumption values are important to young consumers (aged 18–44) in the USA and how such new luxury consumption is driven by their personal values. This research thus has two aims. The first is to define new luxury by examining the consumption values that distinguish it from traditional luxury. The second is to examine the personal values that drive these new luxury consumption values, which affect consumers’ intentions to engage with a new luxury brand.

Design/methodology/approach

Two studies were conducted. In Study 1, a conceptual framework was developed to define new luxury from the consumption value perspective, based on a comprehensive review of the traditional luxury and emerging or new luxury literature. In Study 2, the framework was further extended to include the driving sources (personal values) and the consequences (intentions to engage with a new luxury brand), which were subsequently examined with empirical model testing. The data were collected via an online survey with consumers recruited through Amazon Mechanical Turk (n = 318) and examined with exploratory factor analyses and path analyses.

Findings

The results suggest five major new luxury consumption values that help empirically define new luxury, revealing a trend shift in luxury consumption: inconspicuous consumption, self-directed pleasure, intrinsic experiential value, personal fulfillment and sustainability. Among these five values, three (intrinsic experiential value, personal fulfillment and sustainability) were the most significant factors in directly affecting customer intention to engage with a new luxury brand. The results also found five notable personal values driving new luxury consumption: achievement, benevolence, self-direction, self-esteem and ecocentrism.

Originality/value

While new luxury concepts have been explored conceptually and qualitatively in previous studies, there is a lack of empirical research that clearly defines what new luxury is and that offers testable constructs. This study’s empirical framework for new luxury expands the line of investigation into new luxury consumers, brands and products.

Abstract

Purpose

This study aims to explore how professional event associations’ recovery strategies are perceived by members and to measure the consequent influence of the perceived fit of recovery strategies on organizational identification (OI), consistent behavioral intentions and long-term commitment intentions.

Design/methodology/approach

Data were collected from current members of professional event management associations who work not only as event planners but also as service providers in the hospitality and tourism industry. The authors used partial least squares structural equation modeling to test the proposed model.

Findings

The perceived fit between recovery strategy and internal domains, the self in particular, was found to be the most important in exerting effects directly on OI, and its indirect effects are significant on all the behavioral intentions toward the association, while the perceived fit of recovery strategy with external domains, especially the industry, was not significant with any of the other factors.

Practical implications

The findings from the present study provide professional event association leaderships with significant managerial implications in establishing a sustainable business model to retain current members and increase their intentions toward consistent engagement and long-term commitment.

Originality/value

Stepping forward from the strategic management and organizational behavior literature in the private sector, the authors shed light on a crisis recovery mechanism of professional associations in the event industry, to the best of the authors’ knowledge, the first such attempt in the event management literature.

Abstract

The People’s Republic of China, as a progressively developing economy, is subject to dynamic structural changes, which are potentially de‐stabilizing in nature. Since the end of the 1970s China had abandoned Mao Zedong’s socioeconomic theories and policies and instituted profound socioeconomic reforms. Her more pragmatic approach has increasingly emphasized economic freedom and individualism. The pursued “pragmatism” involves a revolutionary mixture of both a planned and a market economy with greater economic but not political freedom. Essential socioeconomic reforms were not complemented by requisite political reforms. According to Walter Eucken’s “instability thesis,” this may de‐stabilize China’s socioeconomic and political structures. The challenge which China continues to face is how to reconcile two sets of conflicting principles, economic freedom and Marxist‐Leninist‐Maoist control of politics and society, resolving Eucken’s hypothesis of potential long‐term instability. This paper addresses this challenge in terms of ethical and economic perspectives.

Abstract

Purpose

This study aims to aid theory building, the use of decision theory (DT) concepts in sustainable supply chain management (SSCM) research is examined.

Design/methodology/approach

An abductive approach considers two DT concepts, Snowden’s Cynefin framework for sense-making and Keeney’s value-focussed decision analysis, in a systematic literature review of 160 peer-reviewed papers in English.

Findings

Around 60 per cent of the papers on decision-making in SSCM come from operational research (OR), which makes explicit use of DT. These are almost all normative and rationalist and focussed on structured decision contexts. Some exceptions seek to address unstructured decision contexts via Complex Adaptive Systems or Soft Systems Methodology. Meanwhile, a second set, around 16 per cent, comes from business ethics and are empirical, behavioural decision research. Although this set does not explicitly refer to DT, the empirical evidence here supports Keeney’s value-focussed analysis.

Research limitations/implications

There is potential for theory building in SSCM using DT, but the research only addresses SSCM research (including corporate responsibility and ethics) and not DT in SCM or wider sustainable development research.

Practical implications

Use of particular decision analysis methods for SSCM may be improved by better understanding different decision contexts.

Social implications

The research shows potential synthesis with ethical DT absent from DT and SCM research.

Originality/value

Empirical behavioural decision analysis for SSCM is considered alongside normative, rational analysis for the first time. Value-focussed DT appears useful for unstructured decision contexts found in SSCM.

Originality/value
