The purpose of this paper is to explore the factors that influence Chinese apple farmers’ willingness to adopt organic farming, paying a special attention to the role of information acquisition.

Given that the selection bias may occur when farmers themselves decide whether or not to acquire the information to understand the essence of organic farming, this study employs a recursive bivariate probit model to address the issue of the selection bias.

The empirical results indicate that farmers’ decision to acquire information is positively affected by farmers’ environmental awareness, access to credit and access to information. In particular, information acquisition appears to increase the likelihood of farmers’ willingness to adopt organic farming by 35.9 percentage points on average.

The findings suggest that measures increasing farmers’ information exposure can be promising policy interventions to induce adoption of organic farming.

While considerable evidence indicates that organic farming provides more benefits than conventional production practice, little is known about farmers’ willingness to adopt in China. This paper provides a first attempt by examining the role of information acquisition in determining Chinese apple farmers’ willingness to adopt.

Mitigating agricultural greenhouse gas (GHG) emissions is an essential part of China's effort to achieve net-zero emissions. This study assesses the cost-effectiveness of China's agricultural GHG reduction under diverse carbon policies.

The study employs a parametric non-radial distance function approach and estimates the technical abatement potential and marginal abatement cost (MAC) of GHG in China's agricultural sector for the 2008–2017 period.

Agriculture is expected to make a great contribution to China's net-zero emissions progress. This study empirically analyses the cost-effectiveness of China's agricultural GHG reduction under diverse carbon policies. A parametric non-radial distance function approach is used to derive technical abatement potential and MAC of GHG for the 2008–2017 period. The results indicate that no significant improvement had been achieved in terms of agricultural GHG reduction in China during 2008–2017. The country's agricultural sector could reduce 20–40% GHG emissions with a mean value of 31%. In general, western provinces have larger reduction potential than eastern ones. The average MAC for the whole country is 4,656 yuan/ton CO₂e during 2008–2017. For most western provinces, their MAC values are considerably higher than those for most eastern provinces. Compared with previous sectoral estimates of GHG mitigation cost, this study’s estimates indicate that reducing agricultural GHG emissions in some provinces is likely to be cost-effective. The Chinese government should consider expanding its national carbon market to cover agricultural sector.

The Chinese government should consider expanding its national carbon market to cover agricultural sector.

Existing studies in the field mostly ignore input constraints, which is inconsistent with carbon mitigation policy practice, especially in the agricultural sector. This study’s approach integrates both input and output constraints reflecting differing policy practice.

In recent years, “trade up” argument has gained momentum. It argues that international integration can benefit developing countries' environments by fostering the adoption of voluntary environmental standards, such as International Organization for Standardization (ISO) 14001 certification. Based on this argument, a social marketing program that encourages greenness among buyers, especially downstream industrial buyers (for example, auto industry) in developed countries could motivate firms in developing countries go green. The purpose of this paper is to provide an investigation on whether “trade up” is a real hope, and what is required to make it real.

Theoretical modeling and case studies.

This paper finds that international trade does gear up the adoption of ISO 14001 standards in China through increasing pressures from international green customers. However, our analyses suggest that the adoption of ISO 14001 certification does not necessarily improve firms' compliance with existing environmental regulations in China. The actual impact depends on how stringently environmental agency carries out inspections. We also find that in China, ISO 14001 certification motivates little, if any, environmental performance improvement beyond bottom‐line environmental regulations.

This finding suggests that the “trade up” argument as well as a social marketing strategy targeting international buyers (including downstream industries) need to be scrutinized carefully before being used to guide practice.

Few efforts have been made to explore the actual impacts of ISO 14001 certification in developing countries. This paper fills this gap. It provides empirical support for Andreasen's argument that social marketing should be applied more broadly to achieve the desired impacts.

Competitiveness of pharmaceutical companies hugely depends on new knowledge because of ever-changing technologies and forefront of knowledge. Leadership styles appear to influence knowledge management behavior, but there has been little empirical research on employees' knowledge creation behavior as an outcome of leadership. The study examines how task-oriented leadership affects subordinates' knowledge creation behavior. Based on organismic integration theory (OIT), the study proposes that perception of competitive climate and achievement motivation can conduct as mediators.

Data were collected from 877 full-time working employees in five pharmaceutical companies in China. Participants answered demographic questions and completed the task-oriented leadership, perception of competitive climate, achievement motivation, as well as knowledge creation behavior scale. Structural equation modeling was used to test the hypothesized relationships.

The results review that task-oriented leadership will significantly promote subordinates' knowledge creation behavior. Perception of competitive climate and achievement motivation play mediator roles between task-oriented leadership and subordinates knowledge creation behavior. Perception of competitive climate and achievement motivation have a serial mediating effect between task-oriented leadership and subordinates knowledge creation behavior.

By adopting a task-oriented leadership style through training and development, leaders may stimulate employees more knowledge creation behaviors by transmitting the organization's vision, clarifying their work tasks and setting relatively high-performance standards. Then, organizations should establish a competition mechanism to promote competition among employees, while also preventing malicious competition. Finally, organizations should arouse employees' achievement motivation to stimulate their internal pursuit of success and needs.

Because of the improvement of information technology and the acceleration of knowledge dissemination, the need for new knowledge is becoming more and more urgent in organizations. Knowledge, as a resource that needs to be managed in an organizational environment, has regained researchers' attention. However, a flourishing number of studies explain the organizational knowledge management from the macro level, there is a need to explore how leaders influence their subordinates to create knowledge. From the perspective of extrinsic motivation internalization, this study’s findings contribute to the literature on task-oriented leadership and knowledge creation behavior and expand our understanding of why task-oriented leadership promotes subordinates' knowledge creation behavior.

This study aims to contribute to the understanding of the innovation environment of a developing nation through the Triple Helix model, revealing the existing inter-relationships between the three Helixes of Academia–Industry–Government. It sets out to find out the relationship and impact of the three Helixes on the most crucial stage of the innovation process: the commercialisation of patents, and to ascertain if there is a varying impact determined by patent ownership.

This cross-sectional study uses the survey method based on the views expressed by 220 Sri Lankan registered patent holders and categorised by organisational and individual ownership. The sample is drawn from the database of the National Intellectual Property Office of Sri Lanka and patents registered through the Patent Cooperation Treaty, extracted from the World Intellectual Property Organisation Patent Scope database. The survey was carried out in 2019 and limited to patents registered during the period 2010–2014.

The empirical findings indicate weak inter-relationship between Academia support, Industry support and patent commercial success, while the support of the Government Helix is non-significant in the commercial stage. The findings also indicate two different support standards existing in each Helix for the two ownership groups.

The study is limited to a five-year window in a relatively early period in the country’s innovation policy development. The study model is also limited by the non-inclusion of mediators such as government-backed affiliated agencies and academia technical transfer offices which if incorporated would improve the study model and be more reflective of the actual environment and their role as change agents bridging the transition to a hybrid Triple Helix.

The study findings capture the inter-relationships of the Triple Helix existing in a developing country at the most crucial stage of the innovation process. It helps policymakers identify the gaps in each Helix that stands wanting and take measures to rectify them by creating a more favourable National Innovation System. An innovative environment that will facilitate patent holders achieve higher technological transfers and commercial success rates.

The findings disclosure of two different support standards existing in each Helix for the two patent ownership groups poses a challenge for policymakers and challenges the core objective of increasing the commercial success of patents granted. The findings strengthen the need for a more robust support system to be put in place that would empower and facilitate the individual patent owner to increase the share of economic value arising from this underutilised patent group.

This study contributes by furthering the Triple Helix model in a social context and micro-setting by operationalising the theoretical practices. The study also gives insight into each Helix’s interaction and contribution during the most crucial stage of innovation management in a developing economy and its impact on the two categories of patent ownership which is scarce.

The purpose of this paper is to investigate the influence of key parameters on the bond strength and failure modes of laminated structures made of different aluminum alloys (i.e. Al 2024 and Al 7075) via the ultrasonic consolidation (UC) process.

The UC is used to fabricate laminated structures with various parameters. The push-pin tests were performed on the specimens of different materials and parameters, and the force and displacement were recorded during the tests. The peak punch force was used to represent the bond quality of the laminated structure, and the curves of force versus displacement were used to study the failure modes of the structures.

It is found that the lower normal force, the larger vibration amplitude and the lower travel speed can result in stronger bonding. Three different failure modes are observed in the tests, due to the different relations between the toughness of interface and raw materials. The process parameters have influence on the interface toughness of a laminated structure, which further leads to different failure modes.

The overall mechanical properties of a laminated structure highly depend on the bond quality between laminated layers. The push-pin test can easily and effectively evaluate the bond quality of the laminated structure. This paper not only focuses on the bond strength evaluation, but also analyzes the different failure modes of laminated structures made of different aluminum alloys, which can give an opportunity to optimize the parameters for different materials.

The purpose of this paper is to explore the impact of using computers to obtain information on the farm household’s production and consumption based on a field survey of farm households in the northern China.

The most important methods applied are instrumental variable (IV) method and propensity score matching (PSM) method. Estimators of IV, PSM and nearest neighborhood matching approaches are considered together to check the robustness of empirical results.

This paper careful impact evaluation results suggest that the use of computer not only improves the size of arable land rented in but also reduces family labor input intensity and the probability of selling agricultural outputs at farm-gate markets. Moreover, it also stimulates transportation, garment, housing and insurance expenditures per capita.

The database of this research comprises cross-section data, which does not support a cross-time comparison.

These results imply that it is vital to expand the coverage of computer use in rural areas. This may suggest that the importance of improving computer access is crucial for stimulating rural consumption increase. Furthermore, the need for the expansion of internet network coverage in western areas is also of importance.

First, the authors directly estimate computer usage impacts on a broader range of production and consumption indicators by including land-relative investments, variable investments, labor input and household’s expenditure and provide rigorous impact evaluations on the impact of access to computer. Second, the authors use IV and PSM methods to correct self-selection bias, going beyond the single equation approach in other studies. This enables us to identify the causal relationship between computer usage and farmer’s production and consumption decisions.

The purpose of this paper is to investigate the effect of doping element on the microwave absorption performance of hexagonal nano boron nitride (h-nBN)-reinforced basalt fabric (BF)/epoxy composites. A new type of hybrid composite that will be produced by the use of boron nitride as an additive that leads to increased radar absorption capability will be developed and a new material that can be used in aeronautical radar applications.

This study is focused on the microwave absorption properties of h-nBN doped basalt fabric-reinforced epoxy composites. Basalt fabric (BF)/epoxy composites (pure composites) and the BF/h-nBN (1 Wt.% h-nBN doped composites) hybrid composites were fabricated by vacuum infusion method. Phase identification of the composites were performed using X-ray diffraction (XRD), the 2θ scan range was from 10 to 60 with the scanning speed of 3°/min and surface morphologies of the composites were investigated using scanning electron microscopy (SEM). Microwave properties of samples were investigated through transmission/reflection measurements in Agilent brand 2-Port PNA-L Network Analyzer in the frequency range of 3–18 GHz. The prepared sample is positioned between two horn antennas with and without metal plate.

Experimental results show that h-nBN doped composite was synthesized successfully and the produced hexagonal nano boron nitride-added fiber laminated composite material has good absorption behavior when they are used with metallic sheets and good for isolation applications at many points in the 3–18 GHz band.

This paper will contribute to the literature on the use of basalt fabric, which are new types of fibers, and hexagonal nano boron nitride and the effects of boron nitride on radar absorption properties of composite material. It presents detail characterization of each composite by using XRD and scanning electron microscopy.

This paper aims to assess the impact of research in the field of scientometrics by using the altmetrics (social media metrics) approach.

This is an applied study which uses scientometric and altmetrics methods. The research population consists of the studies and their citations published in the two core journals (Scientometrics and Journal of Informetrics) in a period of five years (included 1,738 papers and 11,504 citations). Collecting and extracting the studies directly was carried from Springer and ScienceDirect databases. The Altmetric Explorer, a service provided by Altmetric.com, was used to collect data on studies from various sources (www.altmetric.com/). The research studies with the altmetric scores were identified (included 830 papers). The altmetric scores represent the quantity and quality of attention that the study has received on social media. The association between altmetric scores and citation indicators was investigated by using correlation tests.

The findings indicated a significant, positive and weak statistical relationship between the number of citations of the studies published in the field of scientometrics and the altmetric scores of these studies, as well as the number of readers of these studies in the two social networks (Mendeley and Citeulike) with the number of their citations. In this study, there was no statistically significant relationship between the number of citations of the studies and the number of readers on Twitter. In sum, the above findings suggest that some social networks and their indices can be representations of the impact of scientific papers, similar citations. However, owing to the weakness of the correlation coefficients, the replacement of these two categories of indicators is not recommended, but it is possible to use the altmetrics indicators as complementary scientometrics indicators in evaluating the impact of research.

Investigating the impact of research on social media can reflect the social impact of research and can also be useful for libraries, universities, and research organizations in planning, budgeting, and resource allocation processes.
