Abstract

Purpose

This paper aims to use utilitarian benefits, hedonic benefits and corporate social responsibility to influence the consumer’s sense of brand identity and brand trust in social enterprise products and, thus, favourably affect repurchase intention.

Design/methodology/approach

This study dispatched 430 questionnaires in Taiwan. The top six social enterprises in the organic food industry in Taiwan that accounted for 84.0% of total green organic stores and they were selected for field investigation. This study used structural equation modelling.

Findings

The main path indicates that corporate social responsibility has a largely positive effect going through brand identity and brand trust, and then affecting the decision to repurchase. Therefore, the image of` corporate social responsibility was the greatest driving force. The secondary path indicated that utilitarian benefits positively affected brand identity and brand trust, which, in turn, positively affected repurchase intention. Therefore, utilitarian benefits were the secondary driving force of repurchasing social enterprise products.

Practical implications

This study indicates that social enterprises need to carry out effective corporate social responsibility to create a sense of strong brand trust in consumers’ minds. Empirical results can benefit social marketers for their product launches and promotions. Social enterprises can realize consumer differentiation preferences. With the effective grasp the information of consumer perception, the social marketers can turn passive into active and catch the marketing opportunities by the brand identity and trust to the content of the marketing programs design.

Originality/value

The novelty of this study is to propose an identity-repurchase intention (IRI) model, based on consumer information processing lens and self-congruency theory, to investigate the social enterprise perspective.

Abstract

Purpose

The purpose of this paper is to examine the relationship between US farmers’ adoption of organic farming and direct marketing, both of which are increasingly important practices in the US agricultural and food sector. In addition, the effects of the two practices on farm income are evaluated.

Design/methodology/approach

The research uses the Agricultural and Resource Management Survey from the US Department of Agriculture. Farmers’ adoption of the two practices is modeled with a simultaneous linear probability model, which accounts for the possible linkage between the adoption of the two practices in farmers’ decision-making process. Farm income is modeled with a linear regression model, accounting for the possible endogeneity of the adoption of the two practices.

Findings

The main finding is that farmers’ adoption of organic farming decreases their probability of adopting direct marketing, whereas the reverse effect is insignificant. In addition, organic farming helps to improve gross farm income, whereas the effect of direct marketing is insignificant.

Practical implications

These results facilitate better coordination among numerous government programs aimed at promoting organic farming or direct marketing in the US.

Originality/value

This paper extends previous literature by specifically accounting for the possible linkage between farmers’ adoption of organic farming and direct marketing, and demonstrates that farmers do not make the decision to adopt one particular practice in isolation.

Abstract

Purpose

Ti-Al composite plates have been used in aerospace and other important fields for specific purposes in recent years. However, relatively few studies have concentrated on Ti-Al additive manufacturing because during additive manufacturing process the local fusion and mixing of Ti/Al are inevitable. These areas where Ti and Al are mixed locally, especially interface, could easily generate high residual stresses and cracks. This study aims to manufacture Ti-Al functionally graded material and investigate the interaction of interface.

Design/methodology/approach

In this study, Ti6Al4V/AlSi10Mg functionally graded materials were fabricated by laser based directed energy deposition (L-DED) and a strategy using V interlayer to relieve interfacial stress was investigated.

Findings

The area between the two materials was divided into transition zone (TZ) and remelting zone (RZ). The phase distribution, microstructure and micro-Vickers hardness of the TZ and RZ were investigated. Typical intermetallic compounds (IMCs) such as TiAl3, Ti3Al and Ti5Si3 were found in both composites. The addition of V interlayer promoted the homogenization of IMCs near interface and led to the formation of new phases like V5Si3 and Al3V.

Originality/value

The solidification process near the interface of Ti-Al functionally graded material and the possible generation of different phases were described. The result of this paper proved the feasibility of manufacturing Ti-Al functionally graded material by L-DED.

Abstract

Purpose

In service, the periodic clashes of wheel flat against the rail result in large wheel/rail impact force and high-frequency vibration, leading to severe damage on the wheelset, rail and track structure. This study aims to analyze characteristics and dynamic impact law of wheel and rail caused by wheel flat of high-speed trains.

Design/methodology/approach

A full-scale high-speed wheel/rail interface test rig was used for the test of the dynamic impact of wheel/rail caused by wheel flat of high-speed train. With wheel flats of different lengths, widths and depths manually set around the rolling circle of the wheel tread, and wheel/rail dynamic impact tests to the flats in the speed range of 0–400 km/h on the rig were conducted.

Findings

As the speed goes up, the flat induced the maximum of the wheel/rail dynamic impact force increases rapidly before it reaches its limit at the speed of around 35 km/h. It then goes down gradually as the speed continues to grow. The impact of flat wheel on rail leads to 100–500 Hz middle-frequency vibration, and around 2,000 Hz and 6,000 Hz high-frequency vibration. In case of any wheel flat found during operation, the train speed shall be controlled according to the status of the flat and avoid the running speed of 20 km/h–80 km/h as much as possible.

Originality/value

The research can provide a new method to obtain the dynamic impact of wheel/rail caused by wheel flat by a full-scale high-speed wheel/rail interface test rig. The relations among the flat size, the running speed and the dynamic impact are hopefully of reference to the building of speed limits for HSR wheel flat of different degrees.

Abstract

Purpose

This study aims to explore the effect of the home country institutional environment on firms’ outward foreign direct investment (OFDI) and how it is affected by institutional environment differences across home country subregions. Drawing on transaction cost theory, this paper examined the relationship between the Belt and Road Initiative (BRI) and Chinese firms’ OFDI, as well as the moderating roles of local government officials’ career horizons and state ownership.

Design/methodology/approach

A sample of 5,018 Chinese firm-year observations with foreign investment activities was used over 11 years to estimate a panel-feasible generalized least square regression model.

Findings

The results show that the BRI improves Chinese firms’ OFDI in countries along the BRI route. Furthermore, this positive relationship is weaker for firms where provincial officials have longer career horizons and is stronger for state-owned enterprises (SOEs) compared to non-SOEs.

Originality/value

The findings confirm the positive effect of home country institutional environment on firms’ OFDI. Furthermore, the multiple government perspective offers new insight into the effects of the home country’s institutional environment on OFDI.

Abstract

Purpose

The purpose of this paper is to predict and control the composition during laser additive manufacturing, since composition control is important for parts manufactured by laser additive manufacturing. Aluminum and steel functionally graded material (FGM) were manufactured by laser metal deposition, and the composition was analyzed by means of spectral analysis simultaneously.

Design/methodology/approach

The laser metal deposition process was carried out on a 5 mm thick 316L plate. Spectral line intensity ratio and plasma temperature were chosen as two main spectroscopic diagnosis parameters to predict the compositional variation. Single-trace single-layer experiments and single-trace multi-layer experiments were done, respectively, to test the feasibility of the spectral diagnosis method.

Findings

Experiment results showed that with the composition of metal powder changing from steel to aluminum, the spectral intensity ratio of the characteristic spectral line is proportional to the elemental content in the plasma. When the composition of deposition layers changed, the characteristic spectrum line intensity ratio changed obviously. And the linear chemical composition analysis results confirmed the gradient composition variation of the additive manufacturing parts. The results verified the feasibility of composition analysis based on spectral information in the laser additive manufacturing process.

Originality/value

The composition content of aluminum and steel FGM was diagnosed by spectral information during laser metal deposition, and the relationship between spectral intensity and composition was established.

Abstract

Purpose

The aim of this research is to study the influence of laser additive manufacturing process parameters on the deposit formation characteristics of Inconel 718 superalloy, the main parameters that influence the forming characteristics, the cooling rate and the microstructure were studied.

Design/methodology/approach

Orthogonal experiment design method was used to obtain different deposit shape and microstructure using different process parameters by multiple layers deposition. The relationship between the processing parameters and the geometry of the cladding was analyzed, and the dominant parameters that influenced the cladding width and height were identified. The cooling rates of different forming conditions were obtained by the secondary dendrite arm spacing (SDAS).

Findings

The microstructure showed different characteristics at different parts of the deposit. Cooling rate of different samples were obtained and compared by using the SDAS, and the influence of the process parameters to the cooling rate was analyzed. Finally, micro-hardness tests were done, and the results were found to be in accordance with the micro-structure distribution.

Originality/value

Relationships between processing parameters and the forming characteristics and the cooling rates were obtained. The results obtained in this paper will help to understand the relationship between the process parameters and the forming quality of the additive manufacturing process, so as to obtain the desired forming quality by appropriate parameters.

Abstract

Purpose

Additive manufacturing is a fabrication technology with flexibility and economy. 18Ni300 is one of maraging steels with ultra-high strength, superior toughness, so it is an excellent candidate of structural material. This paper aims to explore the feasibility of using direct laser metal deposition method to fabricate18Ni300, and the evolution of its microstructure and defects is studied.

Design/methodology/approach

The experiments were conceived from single-trace-single-layer (STSL) test to multi-trace-multi-layers (MTML) test via single-trace-multi-layers (STML) test. The microstructure, defects and mechanical properties were analyzed.

Findings

The STML results showed that the columnar/equiaxed transformation occurred at the top part and the grain size increased with the layer number increasing, and it was explained by an innovative attempt combining columnar/equiaxed transformation model and the change of grain size. The MTML test with the interlayer orthogonal parallel reciprocating scanning pattern resulted in the grain growing along orthogonal directions; with the increase of overlap rate, the length and the area of the columnar grain decreased. What is more, the later deposition layer had lower micro-hardness value because of heat history.

Originality/value

Direct laser metal deposition method was a novel additive manufacturing method to manufacture 18Ni300 components, as 18Ni300 maraging steel was mainly manufactured by selective laser melting (SLM) method nowadays. It was useful to manufacture maraging steel parts using direct laser deposition method because it could manufacture larger parts than SLM method. Influence of processing parameters on forming quality and microstructure evolution was studied. The findings will be helpful to understand the forming mechanism of laser additive manufacturing of 18Ni300 components.

Abstract

Purpose

Both foreign and local companies frequently name their brands in foreign language on the market of developing countries, and some of them choose to disclose the brands' country of origin to consumers. The purpose of this research is to investigate the joint effects between the practices of disclosing the actual country of origin of the brands and the language of the brand names on consumers' purchase intention for foreign brands and local brands in developing countries.

Design/methodology/approach

The proposed hypotheses were tested in two studies, namely an experiment and a field experimental survey, with stimuli from two product categories.

Findings

The results of the two empirical studies with Chinese participants consistently demonstrate that revealing the actual country of origin of the brands undermines consumers' purchase intention for local brands that use foreign brand names, but does not impact consumers' purchase intention for foreign brands that use local brand names.

Originality/value

This research first investigates the effects of adapting the brand names into local language of developing countries for brands from developed countries on consumers' purchase intention, which provides new insight into the literature on foreign branding and country of origin effects as well as practical implications for brand managers.
