The trade cost is a significant factor which restricts the trade potential between two nations. This paper aims to make a measurement of agricultural bilateral trade costs of China.

Based on Novy model, this paper makes a measurement of agricultural bilateral trade costs before and after China joining the WTO (1995‐2007).

This paper finds that China's agricultural trade costs with its five major trade partners have not got a pronounced downward trend during 1995‐2007. In ascending order, these are: Malaysia, the USA, Japan, Brazil and Argentina in 2007. Otherwise, there is an obvious corresponding relationship between the trade potential and costs of agricultural products, which is that high costs lead to inadequate trade. With a simple regression, distance and free trade agreement are found to be main factors influencing agricultural trade costs.

Based on the revised gravity model, this paper especially calculates the agricultural bilateral trade costs before and after China joining the WTO, which expands the understanding of trade costs in an industrial perspective. It can prove the agricultural market opening extent, and also help us to learn more about how China participates in the division of the world farm produce market.

The purpose of this paper is to put forward countermeasures to ensure China's energy security based on an analysis of the world energy security situation and challenges China faces in the future in terms of energy security.

An induction approach is adopted to analyze the energy security situation of the world and that of China.

Although available energy resources can meet the medium and long‐term global energy demand, the world energy security faces lots of severe challenges in the aspects of demand and supply factors, infrastructure, geopolitics and strict environmental protection requirements, etc. China's energy supply security faces many challenges in the coming 20 ∼ 30 years or even in the long term. Taking external factors into consideration, the primary challenge is to ensure a stable and sustainable oil supply with reasonable prices. Though the external conditions are of great importance to China's energy security, the influences of domestic factors also need to be well recognized. With energy resources supply being the bedrock of energy security, the establishment of domestic energy market system and energy management framework will exert momentous impact upon the energy security. In addition, while the petroleum supply security is emphasized, attentions should at the same time be paid to the supply security of other energy products, especially to the supply of China's fundamental energy resource of coal.

The paper provides useful and timely analysis of world energy resources, world energy security situation and world economic performances.

The purpose of this paper is to present an approach to reduce energy consumption in data centers. Subsequently, it reduces electricity bills and carbon dioxide footprints resulting from their use.

The authors present a mathematical model of the energy dissipation optimization problem. The authors formulate analytically the server selection problem and the supply air temperature as a non-linear programming, and propose an algorithm to solve it dynamically.

A simulation study on SimWare, using real workload traces, shows considerable savings for different data center sizes and utilization rates as compared to three other classic algorithms. The results prove that the proposed algorithm is efficient in handling the energy-performance trade-off, and that the proposed algorithm provides significant energy savings and maintains a relatively homogenous and stable thermal state at the different rack units in the data center.

The proposed algorithm ensures energy provisioning, performance optimization over existing state-of-the-art heuristics, and on-demand workload allocation.

As a counterproductive interpersonal work behavior, knowledge hiding inhibits team creativity, hampers collaboration and ultimately has a detrimental impact on organizational performance. Drawing upon the impression management perspective. This study aims to investigate how and when employees’ political skill affects their knowledge-hiding behavior in real work contexts.

The authors tested the hypotheses using data gathered from 266 employees in China using a time-lagged research design.

The results indicate that political skill positively influences knowledge hiding through the supplication strategy. Moreover, the positive effect of political skill on this strategy is stronger under higher levels of competition.

A cross-sectional design and the use of self-report questionnaires are the limitations of this study.

The authors contribute to the literature on the emergence of knowledge hiding by identifying an impression management perspective. The authors also contribute to the literature on political skill by exploring the potential negative effects of political skill in the interpersonal interaction. Moreover, the authors enrich the understanding of the literature in competitive climate by introducing the impression management theory and exploring its influence on knowledge floating.

The purpose of this paper is to study the effects of operating conditions including process coefficient, lubricant viscosity and cavitation pressure on the cavitation of spiral groove liquid-film seal (SG-LFS).

A mathematical model of SG-LFS is established based on the JFO boundary and a relative density is introduced. The universal governing equation after a coordinate transformation is discretized by the FVM method and solved by the Gauss-Seidel relaxation scheme.

The results indicate that the two-dimensional size of cavitation and cavitation degree are affected significantly by the process coefficient and lubricant viscosity but the effect of cavitation pressure can be ignored.

The effect mechanisms of operating conditions on the cavitation of SG-LFS are studied by the JFO boundary and cavitation degree characterized by a relative density. The results presented are helpful to perfect and deeply understand the cavitation mechanism of liquid-film seal.

This study argues that leader humility is an important facilitator of team creativity. Based on social learning theory, the study explores a new mechanism that links humble leader behavior to team creativity through a path of team learning.

Data were collected in two private-owned technology companies located in South China. The two-time survey included 77 team leaders and 310 employees. An analysis of time-lagged, multisource data was conducted.

Evidence shows that humble leader behavior promotes team learning behavior through a social learning process, with a subsequent increase in team creativity. This influence is also strengthened when leader effectiveness is high.

Team creativity is an important determinant of organizational success. This research shows that humble leaders can motivate team creativity by acting as a role model. In addition, this research also reminds us that humble leader behavior loses its effect if the leader is incapable.

This research contributes to existing literature on humble leader behavior and team creativity, especially on the mechanisms and contingency effects between these factors.

Platform-based enterprises, as micro-entities in the platform economy, have the potential to effectively promote the low-carbon development of both supply and demand sides in the supply chain. Therefore, this paper aims to provide a multi-criteria decision-making method in a probabilistic hesitant fuzzy environment to assist platform-type companies in selecting cooperative suppliers for carbon reduction in green supply chains.

This paper combines the advantages of probabilistic hesitant fuzzy sets (PHFS) to address uncertainty issues and proposes an improved multi-criteria decision-making method called PHFS-DNMEREC-MABAC for aiding platform-based enterprises in selecting carbon emission reduction collaboration suppliers in green supply chains. Within this decision-making method, we enhance the standardization process of both the DNMEREC and MABAC methods by directly standardizing probabilistic hesitant fuzzy elements. Additionally, a probability splitting algorithm is introduced to handle probabilistic hesitant fuzzy elements of varying lengths, mitigating information bias that traditional approaches tend to introduce when adding values based on risk preferences.

In this paper, we apply the proposed method to a case study involving the selection of carbon emission reduction collaboration suppliers for Tmall Mart and compare it with the latest existing decision-making methods. The results demonstrate the applicability of the proposed method and the effectiveness of the introduced probability splitting algorithm in avoiding information bias.

Firstly, this paper proposes a new multi-criteria decision making method for aiding platform-based enterprises in selecting carbon emission reduction collaboration suppliers in green supply chains. Secondly, in this method, we provided a new standard method to process probability hesitant fuzzy decision making information. Finally, the probability splitting algorithm was introduced to avoid information bias in the process of dealing with inconsistent lengths of probabilistic hesitant fuzzy elements.

This paper aims to explore the relationships among local food consumption experience, cultural competence, eudaimonia, and behavioral intention. Building upon acculturation theory, need hierarchy theory and self-determination theory, the current study develops a conceptual model of local food consumption as international tourists’ acculturation process.

This study collects data from 305 Chinese outbound tourists and uses partial least squares-structural equation modeling to examine the developed model.

The findings reveal a significant effect of the local food consumption experience, consisting of novel, authentic, sensory and social dimensions, on cultural competence, which subsequently evokes eudaimonia and behavioral response toward local food. The mediating effect of cultural competence is also confirmed.

Destination marketers and restaurant managers should recognize local food consumption as a meaningful tool that contributes to tourists’ cultural competence and eudaimonic well-being during travel. They should strive to craft an indigenous consumption setting and provide employee training on the history and culture of local food, helping tourists understand local food customs and embrace different food cultures.

To the best of the authors’ knowledge, very few studies have attempted to examine the meaningful consequences of local food consumption through the theoretical lens of acculturation. This study dives into international tourists’ local food consumption and pioneers a conceptual model to capture how local food consumption experience provokes their eudaimonia and behavioral desires through the mechanism of cultural competence.
