Abstract

Purpose

In this paper, the authors aim to study the relationship between hydrogen embrittlement (HE) susceptibility and cathodic current density applied on the X70 steel girth welds.

Design/methodology/approach

The HE susceptibility of X70 steel girth welds were investigated through slow strain rate tensile test and observed and analyzed by optical microscope and scanning electron microscope methods.

Findings

The results show that HE susceptibility of X70 girth weld was basically unchanged with increasing of ion concentration while gradually increased and maintain at a specific value with the increase of cathodic current density. As for same ion content, a dense calcareous deposit layer generated on the sample surface in soil simulation solution with Ca2+ and Mg2+ resulted a decreased HE susceptibility while the porous calcareous deposit layer resulted a increased HE susceptibility.

Originality/value

A logistic regression model was established to describe the correlation between HE index and the cathodic current density.

Abstract

Purpose

The purpose of this study is to elucidate the effects of electric-arc-induced ablation on the corrosion behavior of pipeline steel in neutral and high pH environments.

Design/methodology/approach

Electrochemical testing, an atmospheric-pressure immersion experiment and various techniques (e.g. scanning electron microscopy, energy dispersive X-ray spectroscopy and X-ray photoelectron spectroscopy) were used to examine the effects of electric-arc-induced ablation on the corrosion behavior of pipeline steel in neutral and high pH environment.

Findings

Electric-arc-induced ablation occurred preferentially in areas of inclusion. The corrosion resistance of an ablation pit was lower than that of non-ablation areas. In the neutral soil solution, general corrosion was the dominant corrosion that affected pipeline steel; the effect of ablation was small but pitting corrosion could still be induced. In a high pH environment, the samples without ablation were passivated, whereas the samples with ablation pits could not be passivated; the ablation pits were likely to develop pitting corrosion.

Originality/value

Electric-arc-induced ablation can reduce the corrosion resistance of pipeline steel under high-voltage direct current interference.

Abstract

Purpose

This study aims to examine how star–nonstar exchange (SNE) influences nonstars’ performance using social information processing theory.

Design/methodology/approach

A time-lagged survey approach is utilized to collect data from 531 nonstars in China. Structural equation modeling and process macro models are applied to test the moderated mediation model of this study.

Findings

Results reveal that SNE has a positive effect on nonstars’ performance through their psychological empowerment, with task complexity moderating the relationship between psychological empowerment and innovative performance. However, no moderating effect was found for routine performance.

Originality/value

Although previous research has delved into how leader–member exchange and team–member exchange influence employee performance. This study uniquely concentrates on how the exchange relationship between star performers and nonstars influences nonstars’ performance – a dimension that has generally been overlooked in existing literature. Findings are important for understanding SNE influence on nonstars’ performance while managing task complexity.

Abstract

Purpose

Skeleton plays an important role in representing the essential feature of garment in image. General skeleton extraction methods often yield many short skeletal branches. Though short branches reflect the geometric details of the garment, they are obstacles in extracting the essential features. The purpose of this paper is to provide an approach to hierarchically remove them to reveal the level of details (LOD) of the skeleton, thus both the essential skeleton and the geometric skeletal branches can be definitely extracted and separated.

Design/methodology/approach

First, the initial garment image skeleton is extracted and smoothed. Then, the hierarchically removing mechanism is established on scoring the importance of each skeletal branch by an altered PageRank method and computing the symmetry among skeletal branches.

Findings

Experimental examples show that this method can extract and separate garment essential skeleton as well as geometric skeletal branches hierarchically. Garments in same class have a similar essential skeleton with detailed differences, so this approach can be potentially applied in garment recognition and style specification.

Originality/value

Traditionally, there is almost no work attempts to build LOD in skeleton of planar shapes. This paper provide an automatic device for building LOD skeleton for garment image. In another word, hierarchic skeletons with details in different prominence level are gradually established. And pairs of symmetric skeletal parts are found by taking advantage of symmetry characteristic of garment. This method is efficient in garment image skeleton extraction.

Abstract

Purpose

The purpose of this paper is to investigate the mediating effects of work-home interference (WHI) on the relationships between work demand, work attitudes, and job performance, with a focus on the moderating effect of Chinese work values (CWV).

Design/methodology/approach

A self-administered survey method was used. The sample comprised 1,032 employees from Mainland China, Hong Kong, and Taiwan. The moderated mediation framework was used to test the proposed model.

Findings

The results showed that WHI mediated the relationships among work demand, job satisfaction, and affective organizational commitment (AOC), but did not mediate the relationship between work demand and job performance. CWV moderated the mediated relationships and exacerbated the mediation effects of WHI on the relationships between work demand and job satisfaction and AOC.

Research limitations/implications

The use of a cross-sectional design prevented the drawing of causal inference. With the exception of job performance, the self-reported measures are all subject to the problem of common method bias.

Practical implications

Organizations in Greater China could implement stress management programs to reduce the negative effects of work demands. HR practitioners and managers should understand what values their employees hold to provide the proper interventions for them.

Originality/value

By integrating both the mediator (WHI) and a moderator (CWV), this study investigated how CWV, an individual-level cultural value, affects the influences of WHI. The results highlight the importance of incorporating culturally specific value constructs when examining the underlying mechanisms of WHI.

Abstract

Purpose

Clothing retrieval is very useful to help the clients to efficiently search out the apparel they want. Currently, the mainstream clothing retrieval methods are attribute semantics based, which however are inconvenient for common clients. The purpose of this paper is to provide an easy‐to‐operate apparels retrieval mode with the authors' novel approach of clothing image similarity measurement.

Design/methodology/approach

The authors measure the similarity between two clothing images by computing the weighted similarities between their bundled features. Each bundled feature consists of the point features (SIFT) which are further quantified into local visual words in a maximally stable extremal region (MSER). The authors weight the importance of bundled features by the precision of SIFT quantification and local word frequency that reflects the frequency of the common visual words appeared in two bundled features. The bundled features similarity is computed from two aspects: local word frequency; and SIFTs distance matrix that records the distances between every two SIFTs in a bundled feature.

Findings

Local word frequencies improves the recognition between two bundled features with the same common visual words but different local word frequency. SIFTs distance matrix has the merits of scale invariance and rotation invariance. Experimental results show that this approach works well in the situations with large clothing deformation, background exchange and part hidden, etc. And the similarity measurement of Weight+Bundled+LWF+SDM is the best.

Originality/value

This paper presents an apparel retrieval mode based on local visual features, and presents a new algorithm for bundled feature matching and apparel similarity measurement.

Abstract

This article represents an empirical examination of green logistics awareness of employees at third-party enterprises in China. The data used for this study was collected using a survey related to green logistics awareness. Participants were employees of Chinese enterprises, including five logistics companies. Although there was a general low level of green logistics awareness, results showed a diverse awareness of the topic contingent upon green logistics knowledge. More specifically, with the exception of those who demonstrated a high degree of green logistics knowledge, green logistics awareness level and other dimensions were low. In addition, educational background demonstrated an influence on green logistics awareness. The findings from this study have real-world implications for the development of state logistics environmental protection policy.

Abstract

Purpose

This paper aims to investigate the relationship between external regulation pressure and corporate social responsibility (CSR) reporting decision and comprehensiveness and the relationship between block ownership and CSR in China.

Design/methodology/approach

This paper provides descriptive statistics of the current state of CSR reporting in China. In addition, regression models are utilized to analyze the behavior of CSR reporting of a sample of 5,334 listed firms in China.

Findings

Our paper records a significant increase of CSR reporting in the period of 2008-2010. Using a sample of 5,334 listed firms in China, we find a positive yet weak association between centrally controlled state-owned enterprises (SOEs) and CSR reports. Moreover, we find that firms with more concentrated block ownership are less likely to issue CSR reports.

Research limitations/implications

Taken as a whole, our analyses suggest that the entrenchment effect from blockholders seems to dominate the incentive effect and this depresses the quality of CSR reports.

Practical implications

Despite the well-known effect of economic factors on CSR decision, corporate governance such as ownership structure could complicate the final results. Furthermore, the institutional background of the country and its implications for corporate governance should be considered jointly and concurrently.

Social implications

The positive effect from regulatory pressure on centrally owned SOEs suggests that regulation remains an effective tool to encourage CSR reporting in emerging markets.

Originality/value

First, our study confirms prior research that CSR disclosure decision is primarily driven by economic and strategic considerations. Moreover, our results suggest that a country’s institutional background, in addition to economic and strategic considerations, influences the decision and quality of CSR disclosures. Second, we extend the literature on ownership structure, particularly with respect to blockholders. Third, our research design addresses a weakness in earlier studies which are biased exclusively on state ownership to the exclusion of all other blockholders.
