Abstract

Purpose

This paper aims to describe carbon fiber reinforced plastics (CFRP) bars as a way to strengthen a 40-year-old stone arch bridge. To investigate effectiveness of the strengthening method, fielding-load tests were carried out before and after strengthening.

Design/methodology/approach

High-strength CFRP bars with minor radius, high tensile strain and good corrosion resistance were used in this reinforcement. The construction process for strengthening with CFRP bars – including CFRP bars cutting, crack grouting, original structural surface treatment, implant drilling, CFRP bars installation and pouring mortar – was described. Ultimate bearing capacity of the bridge after strengthening was discussed.

Findings

The results of concrete stress and deflection show that the strength and stiffness of the strengthened bridge are improved. The strengthened way with CFRP bars is feasible and effective.

Originality/value

This paper describes CFRP bars as a way to strengthen a 40-year-old stone arch bridge.

Abstract

Purpose

This paper aims to examine the effect of dividend regulation on cost stickiness (i.e. the asymmetric change in firm expense between sales increase and sales decrease) and explore the underlying mechanism.

Design/methodology/approach

Based on the quasi-natural experiment of the Guideline for Dividend Policy of Listed Companies issued by the Shanghai Stock Exchange (SSE) in 2013, the authors employ a difference-in-difference model to investigate the impact of dividend regulation on cost stickiness.

Findings

The authors find that the cost stickiness of treatment group firms has decreased significantly when compared with control group firms after the dividend regulation. Moreover, this effect is more pronounced among firms in lower marketization regions, in lower competition industries and those with less analyst coverage and lower cash flow levels. Further analyses show that dividend regulation reduces the cost stickiness of firms by mitigating agency problems. Finally, the conclusion holds after several robust tests, including controlling for firm fixed effect, propensity score matching (PSM), placebo test and reconstruction of expense variable.

Originality/value

This paper confirms that dividend regulation serves an important role in corporate governance, which reduces firms' agency costs and thereby decreases cost stickiness. The conclusions shed light on the dividend policies of listed companies and capital market regulation in the future.

Abstract

Purpose

This review aims to summarize previous research on work–family relationships in the tourism and hospitality contexts. It then integrates the various approaches into a holistic model and identifies important areas for future research.

Design/methodology/approach

Over 150 research papers from the past 20 years were retrieved from Elsevier Science Direct, SAGE, Emerald, Taylor & Francis and EBSCOHost. In total, 77 papers reporting empirical research were analyzed in terms of concepts, theories, antecedents, consequences and methods.

Findings

The major findings on work and family issues in the tourism and hospitality contexts were synthesized. Critical topics for future research were identified. A holistic model of the factors that affect work and family was developed to improve the consistency of future research.

Research limitations/implications

An overview of work–family studies will provide a solid research background to tourism and hospitality faculty members and graduate students who are considering research in this area. This paper is a general review of previous research, and the review focus is relatively global.

Originality/value

This paper is the first comprehensive summary and narrative review of work and family studies in tourism and hospitality.

Abstract

Important developments of China's securities markets within the last two years, namely, the Share Reform, the warrant market, the innovative listed open-end funds (and exchange-traded funds), corporate bonds with detachable warrants, exchange-traded asset-backed securities, are described. The discussion focuses on unique, innovative features of these products, as compared to their counterparts available in more mature markets (when applicable), and points to possible future research themes. The proposed rules with regard to stock index futures and credit trading are also discussed.

Abstract

Purpose

The silicone modifications of two-component epoxy resin coatings are commonly built on epoxy resins rather than on epoxy curing agents. The silicone-modified epoxy curing agent system is rarely reported yet. This study aims to prepare the polysiloxane (PS)-modified waterborne epoxy coatings based on aqueous curing agents technology.

Design/methodology/approach

Waterborne epoxy curing agents with different contents of terminal epoxy PS were synthesized by reacting with triethylenetetramine, followed by incorporating of epoxy resin (NPEL-128) and polyethylene glycol diglycidyl ether. The waterborne epoxy coatings were prepared with the above curing agents, and their performance was investigated through thermogravimetric analysis, scanning electron microscopy, mechanical characterization, gloss measurement, chemical resistance test and ultraviolet (UV) aging experiment.

Findings

The results showed that the epoxy coating prepared by silicon-modified curing agent has higher gloss, better chemical resistance and UV resistance than the coating from unmodified curing agent with terminal epoxy PS and commercially available waterborne epoxy curing agent (Aradur 3986), as well as the competitive mechanical properties and heat resistance. Reduced water absorption on fibrous paper was also obtained with the help of silicon-modified curing agent.

Originality/value

These findings will be valuable for resin researchers in addressing the modification issues about waterborne epoxy resin and curing agent.

Abstract

Purpose

The purpose of this paper is to discuss characteristics of organic food value chain governance and policy tools that can increase the supply of good quality of agri-products.

Design/methodology/approach

This paper discusses a national organic food supply system in China, identifying the link between an organization form with a social confidence crisis and information asymmetry as the main challenges. It develops an analytical model of the market structure of organic certification based on the contract theory, which considers the certification incentive driven by both farmers and processors. Two cases of raw milk producers and processors provide empirical data.

Findings

The argument which is brought forward is that product information asymmetry together with strict requirement for ensuring organic food integrity brings the organic milk value chain into a highly integrated organization pattern. A tight value chain is effective in the governance of organic food supply chain under third party certification (TPC), while a loose value chain discourages producing organic products because of transaction costs. TPC is found to be a positively correlation with a tight value chain, but it brings high organizational cost and it raises cost for consumers.

Originality/value

This is the first paper discussing the governance of organic food value chain in Chinese milk industry.
