Abstract

Purpose

Using Shanghai as an example, the purpose of this paper is to perform grade evaluation and zoning for different land use spaces by GIS by identifying the major restrictive factors in current socio-economic development.

Design/methodology/approach

Based on short plate theory, 11 major restrictive indicators that will restrict socio-economic development in Shanghai are identified, and urban land is divided into four subspaces and the restrictive grade evaluation of urban land subspace is achieved with GIS spatial analysis; then, land development zoning is processed according to the results of the evaluation.

Findings

In all, 11 major restrictive indicators that will restrict socio-economic development in Shanghai are identified. The restrictive grades of the agricultural production, urban construction and ecological protection subspaces are mainly common, weak and weaker, and the relatively strong restrictive grade of industrial development subspace is mainly concentrated in the more developed industrial districts (counties). The areas of the common and good regions of constructive development and ecological development zones account for 87.4 and 98.3 per cent of each total area, respectively, and urban land still has significant development potential in Shanghai.

Originality/value

This paper proposes various urban land space evaluations and zoning strategies based on restrictive indicators and perspectives, enriching the ideas and methods of urban land use evaluation.

Abstract

Purpose

Non-financial corporate debt is one of the important sources of systematic risk in the real economy. Assessing a measure of systematic risk in corporation debt is currently a key challenge. In this regard, we propose a two-tier risk contagion networks model.

Design/methodology/approach

Assessing a measure of systematic risk in corporation debt is currently a key challenge. In this regard, we propose a two-tier risk contagion networks model based on four dimensions: concept definition, data structure, risk contagion network construction, and risk measurement indicators construction. We take the Jiangsu bond issuer guarantee network as a sample area.

Findings

Taking the Jiangsu bond issuer guarantee network as a sample area, we find that there is a strong correlation between the debts of non-financial corporation in China, and it is easy to become a potential regional systematic risk source. In addition, our empirical research also reveals that external risk exposure and node degree of network are two key indicators when identifying key risk-contagion enterprises.

Originality/value

The main contributions of this study are two-fold. First, this article proposes a two-tier risk contagion networks model to measure systematic risk in non-financial corporation. Second, this article describes the structure of the corporate risk contagion network.

Abstract

Purpose

High-ductility cementitious composites (HDCC) have an excellent crack controlled capacity and corrosion resistance capacity, which has a promising application in structure engineering under harsh environment. The purpose of this study is to explore the corrosion mechanism of steel bar in HDCC.

Design/methodology/approach

Intact and the pre-cracked HDCC specimens under the coupled action of different dry–wet cycles and chloride attack were designed, and intact normal concrete (NC) was also considered for comparison. Corrosion behavior of a steel bar embedded in HDCC was analyzed by an electrochemical method, a chloride permeability test and X-ray computed tomography.

Findings

Steel corrosion probability is related to the chloride permeability of the HDCC cover, and the chloride permeability resistance of HDCC is better than that of NC. Besides, crack is the key factor affecting the corrosion of steel bars, and the HDCC with narrower cracks have a lower corrosion rate. Slight pitting occurs at the crack tips. In addition, the self-healing products and corrosion products fill up the cracks in HDCC, preventing the external aggressive ions from entering and thereby decreasing the steel corrosion rate.

Originality/value

HDCC has a superior corrosion resistance than that of NC, effects of variable crack width on corrosion behavior of steel bar in HDCC under the coupled actions of different dry–wet cycles and chloride attack are investigated, which can provide the guide for the design application of HDCC material in structure engineering exposed to marine environment.

The purpose of this paper is to examine the effect of credit constraints on agricultural productivity in China.

Abstract

Purpose

The purpose of this paper is to examine the effect of credit constraints on agricultural productivity in China.

Design/methodology/approach

Using data from a rural financial survey, a switching regression model is used to account for endogeneity and heterogeneity. Carter presents three ways that credit might affect the production functions; a shift along a given production surface by allowing an optimal level of inputs, a shift the production surface out by allowing the purchase of more efficient inputs, and the third is to increase net revenue by more intensive use of fixed inputs and resources. Thus, the effects of factors on agricultural productivity may not be independent of credit status; therefore, separate functions for credit‐constrained and non‐constrained households are examined.

Findings

Empirical estimates of the impacts of credit constraints on agricultural productivity are provided for the Heilongjiang province, a major agricultural production area, in Northeast China. By removing credit constraints, average agricultural productivity was estimated to be increased by 75 percent. Under credit constraints, labor inputs, along with a farmers' education, cannot be fully employed because of an inappropriate mix of inputs.

Research limitations/implications

Young farmers may not be able to leverage their comparative advantage for physically intensive farm work under credit constraints. Because of data limitations, the research does not include information on informal credit in the estimation, which may underestimate the effects of credit constraints.

Originality/value

This study provides an analysis of the impacts of credit constraints on rural household productivity for the Heilongjiang province, a major agricultural production region, in Northeast China.

The purpose of this paper is to investigate the conceptual and empirical issues related to sexual harassment (SH) in a police department in Taiwan.

Abstract

Purpose

The purpose of this paper is to investigate the conceptual and empirical issues related to sexual harassment (SH) in a police department in Taiwan.

Design/methodology/approach

Survey data were collected. Through the analysis, the paper proposes that SH can be better divided into two subcategories: quid pro quo and hostile work environment harassment. Multivariate analysis is used to explore the sources of SH.

Findings

It was found that both types of SH can be better explained by work environment variables than by demographic variables, but the specific sources differ. Hostile work environment harassment is predicted by the extent to which female officers perceive or experience that deployment and transfer practices are influenced by their gender. Quid pro quo harassment is related to job barriers and dodging from work.

Research limitations/implications

The two scales used in this research have captured the core of SH, but they might not fully depict the nature of SH in the police department in Taiwan. The sample was limited to the largest police department in Taiwan and it may not represent the entire police in Taiwan.

Practical implications

If hostile work environment and quid pro quo harassments are related to different organizational factors, it is useful for policy makers in the police to differentiate these two different types of SH and develop differential prevention and response measures.

Originality/value

This paper highlights the need to differentiate quid pro quo and hostile work environment harassments. It fills a gap in the literature by providing the baseline information on the prevalence of SH in one police department in Taiwan and by examining sources of SH in a profession dominated by males.

Abstract

Purpose

This paper aims to deduce a set of theory computational formula, and optimize and improve the heat conductivity of vias in printed circuit boards of electrical power apparatus.

Design/methodology/approach

The authors adopted numerical simulation and experimental measurement to verify the reliability of this formula.

Findings

Research result showed that 0.45 mm was the optimal bore diameter of vias; the conductivity had no obvious improvement when filling material was FR4 or Rogers, but if it was filled with texture of high thermal conductivity like soldering tine, the conductivity would improve a lot; the plating thickness of vias had a greater influence on thermal conductivity.

Originality/value

Through the theory computational formula, this paper studied the influence of aperture of vias, filled materials and thickness of copper plated on vias on thermal conductivity.

Abstract

The aim of this study is to examine the determinants of students’ perceptions of the Green University. The authors also examine whether students’ perceptions of the Green University are determined by the type of sustainability-related subjects that they have been taken to date. The authors divided sustainability-related subjects into those related to economics, social, and environment. The authors also compare students’ perceptions by different university types (public vs. private) as well as students from different majors (economics and business vs. engineering). The authors use questionnaires for data collection where respondents are undergraduate students in Jakarta, Indonesia. The result shows that on average our respondents have positive perceptions about Green University practices. However, the authors also find that students’ perceptions variate across university types. The authors also find that students’ perceptions about the importance of Green University are not positively affected by sustainability-related subjects. The authors find that public university students have higher and significant perceptions about the Green University, whereas students’ majors have no significant effects.

Abstract

Purpose

The purpose of this paper is to compare the effectiveness of different analytical approaches, namely artificial neural networks, logistic regression and support vector machines to assess the health of a strainer located at the suction side of the pump.

Design/methodology/approach

Data used for simulation included exemplars from clean (represented by datasets after cleaning the suction strainer) and faulty conditions (represented by datasets prior to cleaning the suction strainer). The same datasets were used for modeling in order to compare how different techniques perform when fed with the same information.

Findings

Principal component analysis‐based artificial neural networks proved to be better than other techniques in classifying maintenance datasets and predicting flow resistance from a clogged suction strainer.

Originality/value

The work highlights the comparative effectiveness of three predictive analytical techniques in classifying real plant data from a suction strainer. This will provide an opportunity for maintenance experts to see the effectiveness of different techniques as well as revealing valuable information about the relationship between the condition of the suction strainer and the overall performance of the pump.

Abstract

Purpose

Although a substantial body of literature investigates the determinants of audit report lag (ARL), scant empirical evidence exists on the consequences of ARL. The purpose of this paper is to examine the association between abnormally long ARL and future stock price crash risk.

Design/methodology/approach

This quantitative study employed a large scale (14,445 firm-year observations) of annual financials, audit and ownership information for the Chinese listed companies during 2002–2013 which were retrieved from the China Stock Market and Accounting Research database.

Findings

This study finds evidence that abnormally long ARL increases the risk of a future stock price crash. Furthermore, the study finds that this adverse consequence is more pronounced for firms with a poor internal control environment.

Practical implications

Recently literature started to explore the consequences of abnormal ARL such as going concern audit opinion and restatements in the subsequent periods. This paper reveals that abnormal ARL has consequences for investor wealth losses as well. This is relevant in China, where the ongoing economic growth has attracted, and will continue to attract, a growing body of domestic and international investors. Understanding what factors could expose investors to wealth losses is of paramount importance for allocating their scarce capital.

Originality/value

This study extends the scant literature on the consequences of ARL, and provides useful insights for the Chinese regulatory authorities when considering the appropriateness of the current filing deadline for listed firms.
