Abstract

Purpose

This paper aims to show a series of hydrogels with adjustable mechanical properties, which can be cured quickly with visible light. The hydrogel is prepared conveniently with hydroxyethyl acrylate, cross-linker, gelatin and photoinitiator, and can be printed into certain 3D patterns with the direct ink write (DIW) 3D printer designed and developed by the research group.

Design/methodology/approach

In this paper, the authors designed a composite sensitization initiation system that is suitable for hydrogels. The concentration of photoinitiator, gelatin and cross-linker was studied to optimize the curing efficiency and adjust the mechanical properties. A DIW 3D printer was designed for the printing of hydrogel. Pre-gel solution was loaded into printer for printing into established models. The models were made and sliced with software.

Findings

The hydrogels can be cured efficiently with 405-nm visible light. While adding various content of gelatin and cross-linker, the mechanical properties of hydrogels show from soft and fragile (elastic modulus of 121.18 kPa and work of tension of 218.11 kJ·m−3) to rigid and tough (elastic modulus of 505.15 kPa and work of tension of 969.00 kJ·m−3). The hydrogels have high capacity of water absorption. With the DIW 3D printer, pre-gel hydrogel solution can be printed into objects with certain dimension.

Originality/value

In this work, a composite sensitization initiation system was designed, and fast curing hydrogels with adjustable mechanical properties had been prepared conveniently, which has high equilibrium water content and 3D printability with the DIW 3D printer.

Abstract

Purpose

This study examines the impact of network embeddedness (NE) on innovation performance in small- and medium-sized enterprises (SMEs), and analyses absorptive capacity as mediator and openness as moderator.

Design/methodology/approach

Data were collected from 209 employees of SMEs using a convenient sampling technique. Partial least squares structural equation modeling in SmartPLS was used to analyze the various constructs.

Findings

The results exhibit a positive and significant relationship in NE and absorptive capacity. Also, this study found a positive and significant relationship in absorptive capacity and innovation performance. Moreover, absorptive capacity has a positive and significant mediation role in the relationship between NE and innovation performance. Also, openness positively moderated the relationship of NE and absorptive capacity.

Practical implications

SMEs should try to implement the functions of NE, such as interaction with other firms in higher frequency, developing trust among all parties, clear alliance among the partners to enhance innovation performance. Similarly, SMEs should focus on absorptive capacity and openness to enrich innovation performance.

Originality/value

This study adds in the current literature of the chosen constructs and empirically contributes the effects in the manufacturing industry of Jiangsu Province, China.

Abstract

Purpose

The purpose of this paper is to analyze the heterogeneity of regional grain production distribution in China, by examining the regional heterogeneity of absolute and relative changes in grain planting acreage, and explain it in terms of increasing labor costs and difficulties in agricultural inputs adjustment.

Design/methodology/approach

The study uses data from official statistical yearbooks and the satellite remote sensing image data of Landsat TM 30 m. Multivariate analysis is conducted to examine the effect of labor cost, difficulty in replacing agricultural input factors and other factors underpinning changes in grain acreage and grain structure adjustment.

Findings

The heterogeneity of changes in grain acreage and proportion of arable area for grain production are mainly determined using the labor cost and difficulties in the replacement of agricultural input factors.

Originality/value

To the best of the authors’ knowledge, this study is the first to systematically analyze the heterogeneity in restructuring grain production at provincial level and its causes. The results not only provide evidence of grain production restructuring at regional level, but also contribute to the understanding of the law of structural change in agricultural production.

Abstract

Purpose

This paper attempts to deploy a systematic and structural approach to examine Macau's strengths and weaknesses and to scan its external opportunities and threats. A fresh way to quantify the extent of perceived opportunities and threats is introduced here. This is adopted and modified from the quality management tool box, i.e. the failure mode and effects analysis (FMEA) and success mode and effects analysis (SMEA).

Design/methodology/approach

The internal factors, i.e. its strengths and weaknesses are systematically and structurally gauged using a Likert scale of 0 to 10 (i.e. 0 representing least important or least well performed … to 10 representing most important and best performed).

Findings

Following the matching of internal factors with the external factors in the strengths, weaknesses, opportunities, and threats (SWOT) analysis, a list of meaningful responses is identified as possible strategies for the Macau SAR Government. The SWOT analysis is simple to use yet powerful and flexible in responding to changes in the external environment and should be useful to organizations both in the commercial sector and government machinery.

Originality/value

This innovative and structured strategic formulation approach is useful to both business practitioners and management consultants.

Abstract

Purpose

The purpose of this paper is to produce a high-quality measure of the nature of healthcare resources available in China’s Township Health Centers (THCs), paying particular attention to equity between high- and low-income areas.

Design/methodology/approach

This study makes use of data from a nearly nationally representative survey in rural China conducted by the Center for Chinese Agricultural Policy at the Chinese Academy of Sciences in 2011. The samples of towns were selected randomly from 25 counties located in five provinces from different regions of China. Data were collected through questionnaires and direct observation.

Findings

The THCs located in rich areas have higher levels of human resources than poor areas. THCs in rich areas also have more fixed assets than those in poor areas. In fact, even though the Chinese Ministry of Health mandates that all THCs have certain basic levels of medical equipment and facilities, many THCs in poor areas do not have them. The allocation of mandated equipment is unequal.

Practical implications

These findings suggest that China’s government should pay more attention to THCs located in poor areas, especially in light of new initiatives to improve health care in poor rural areas.

Originality/value

This is the first nationally representative study to employ rigorous empirics to investigate the extent of inequality in allocation of resources within THCs across China.

Abstract

Purpose

The purpose of studying the low voltage direct current (DC) microgrid, which uses computerised control system techniques, an orderly coordination control stratagem considering optimisation of a hybrid energy storage system (HESS) was projected in this paper.

Design/methodology/approach

The projected control stratagem was divided into three levels: topmost power dispatch level, transitional bus voltage regulation level and bottommost converter control level.

Findings

At the topmost power dispatch level, the cost of system stability was introduced, which is related with state of charge and discharging power of HESS.

Originality/value

Furthermore, the cost of system stability and HESS depreciation was compared with commercial price, and HESS switches its operating mode to discharge more at higher price or charge more at lower price to ensure the DC microgrid in economic operation. At the transitional bus voltage regulation level, DC bus gesturing is used as a control signal to achieve an autonomous decentralised operation of DC microgrid. The Matlab/Simulink simulation inveterate that the economical and autonomous decentralised operation can be achieved through the control stratagem.

Abstract

Purpose

The purpose of this paper is to find an incentive strategy to enhance the interests of the main manufacturer by inducing the suppliers to conflict the fixed incentive provided by the main manufacturer.

Design/methodology/approach

The main manufacturer‐supplier model is widely applied in the R&D procedure of complex products such as aeroplanes. Because of the uncertainty in the R&D, the effort of the suppliers has an important effect on it. Considering the dynamic interaction between the main manufacturers and suppliers, with the main manufacturers as leaders and suppliers as followers, this paper establishes a Grey‐Stackelberg model to analyze the best change of the incentive strategies of the main manufacturers and the effort strategies under incentive‐conflict of suppliers under the uncertain environment. A numeric example is also computed in the last part of the paper.

Findings

The results show that the main manufacturer can increase its benefit without damaging the interests of suppliers by controlling the fixed incentives.

Originality/value

The paper succeeds in establishing the Grey‐Stackelberg model by analysing the grey area among the main manufacturer and the suppliers, and helps to develop grey systems theory.
