The purpose of this paper is to clarify agricultural services into five categories, including agricultural materials supply service, financial service, technical service, machinery service and processing and sales service, and to examine the effect of agricultural services on cost saving of rice production in China.

Based on a three-year panel data set covering 3,421 rice farmers in 12 Chinese provinces collected from the state rice industry experiment stations’ fixed watch points of China Agriculture Research System, a stochastic frontier model which takes the price vectors of input variables into cost function is developed by stochastic frontier analysis method in the study.

There is a deviation between the actual cost and the minimum cost on rice production in China due to the loss of cost efficiency, whose score is 0.7983 at the mean. Agricultural services can help improve cost efficiency, thus contributing to cost saving. Specifically, the effect of technical service on cost saving is the highest, followed by processing and sales service, machinery service, financial service and agricultural materials supply service.

The results of this paper are of great significance to the effectiveness and efficiency of the targeted agricultural services and indicate implications for policy improvement under the context of clear upward trend of agricultural production costs.

Drawing on signaling theory and social capital theory, this study aims to examine the underlying mechanisms and contingencies of the relationships between social capital (SC) and collaboration in buyer-supplier relationships (BSRs). This is achieved by evaluating the mediating effect of psychological contract fulfillment (PCF) and the moderating roles of guanxi orientation and market uncertainty.

The current study used a survey method to collect data from 271 buyers in China. Structural equation modeling (SEM) and moderated regression analysis were applied to examine the hypotheses.

The positive effect of structural and relational SC on buyers’ collaborative behaviors is partially mediated by buyers’ PCF. In contrast, the positive effect of cognitive SC on collaboration is fully mediated by buyers’ PCF. Guanxi orientation strengthens the indirect effect of buyers’ PCF on the cognitive SC-collaboration relationship and relational SC-collaboration relationship. Market uncertainty amplifies the relational SC-collaboration relationship.

Prior studies have presented mixed evidence of the effect of SC on collaboration and have paid little attention to the underlying mechanisms and conditions moderating the effect. This research proposes a theoretical model that integrates signaling theory and social capital theory to explore how three dimensions of SC can enhance buyer collaboration through buyers’ PCF under different levels of guanxi orientation and market uncertainty.

This study aims to explore the domain of leader’s creativity and suggests that leader’s creativity can be present as both worker-role creativity and manager-role creativity. Then, the study examines the influence of leader’s worker-role creativity and manager-role creativity on employees’ creativity and team creativity. As a contextual factor, the identification with leader is taken as a moderator at both the individual and team levels.

With data that was collected from 229 employees and 32 team leaders in entrepreneurial and R&D teams of China, hierarchical regression is conducted to test the hypotheses at individual and team levels separately.

The results show that leader identification plays a different role in moderating the effects of worker-role creativity and manager-role creativity on employees’ and team creativity. For the relationships between worker-role creativity and employees’ and team creativity, they are positive when leader identification is high and negative when it is low. For the relationships between manager-role creativity and team creativity, it is stronger when leader identification is higher rather than lower.

This study answers the call for studying the roles of creative role models and provides new evidence of the leader as a role model. The exploration of the domain of leader’s creativity and the different effects on creative outcome brings an interesting perspective on creativity and leadership research.

The present study draws on the advance to develop the content of leader’s creativity. Then, the moderating role of identification with leader between leader’s creativity and employees’ creativity and team creativity is comprehensively examined.

Although entrepreneurial learning is widely believed as an important factor in shaping one’s entrepreneurial intention, research finds little consistent results on the direct effect of entrepreneurial learning on one’s entrepreneurial intention. To solve the conflicted effects of entrepreneurial learning, the purpose of this paper is to explore how entrepreneurial learning may impact individual entrepreneurial intention.

Drawing on the theory of planned behavior (TPB), the authors proposed and tested on a three mediating effect model, in which entrepreneurial learning is associated with entrepreneurial intention through attitude, subjective norm and perceived behavioral control toward entrepreneurship. Moreover, the moderating role of prior exposure to entrepreneurship was proposed and tested. Based on a sample of 200 university students who have taken entrepreneurial courses in Hong Kong, the hierarchical regressions and moderated mediation tests were used to test the hypotheses.

The authors find that the positive relationship between entrepreneurial learning and entrepreneurial intention is significantly mediated by attitude, subjective norm and perceived behavioral control toward entrepreneurship; and the mediating effects of entrepreneurial learning on entrepreneurial intention via attitudes and perceived behavioral control respectively, is moderated by exposure to entrepreneurship.

Contributing to the literature of entrepreneurship education, this study identifies individuals who exposed to the same entrepreneurship education may perform differently in entrepreneurial learning. The findings also help us to better understand the mechanism through which and under which context one’s entrepreneurial learning may enhance his/her entrepreneurial intention.

Whether shareholders’ involvement in management benefits the organization’s performance remains inconclusive. The purpose of this study is to reconcile the conflicting results by exploring whether and under which contexts shareholder involvement may impact firm innovation performance.

This study attempts to combine previous theoretical views (reactance and agency theories) to examine a curvilinear effect of shareholder involvement on firm innovation performance based on governance related to cost-benefit analysis. Drawing on data from 174 Chinese manufacturing firms, the hierarchical regressions were used to test the hypotheses.

The study finds that shareholder involvement has a U-shaped relationship with firm innovation performance. Moreover, ownership incentive strengthens the U-shaped relationship, while monitoring weakens it.

Examination of the U-shaped main effect of shareholder involvement and these contingent factors further explains the mixed empirical results concerning the link between shareholder activism and firm-level performance.

The ecological environment of the Loess Plateau, China, is extremely fragile under the context of global warming. Over the past two decades, the vegetation of the Loess Plateau has undergone great changes. This paper aims to clarify the response mechanisms of vegetation to climate change, to provide support for the restoration and environmental treatment of vegetation on the Loess Plateau.

The Savitsky–Golay (S-G) filtering algorithm was used to reconstruct time series of moderate resolution imaging spectroradiometer (MODIS) 13A2 data. Combined with trend analysis and partial correlation analysis, the influence of climate change on the phenology and enhanced vegetation index (EVI) during the growing season was described.

The S-G filtering algorithm is suitable for EVI reconstruction of the Loess Plateau. The date of start of growing season was found to gradually later along the Southeast–Northwest direction, whereas the date of the end of the growing season showed the opposite pattern and the length of the growing season gradually shortened. Vegetation EVI values decreased gradually from Southeast to Northwest. Vegetation changed significantly and showed clear differentiation according to different topographic factors. Vegetation correlated positively with precipitation from April to July and with temperature from August to November.

This study provides technical support for ecological environmental assessment, restoration of regional vegetation coverage and environmental governance of the Loess Plateau over the past two decades. It also provides theoretical support for the prediction model of vegetation phenology changes based on remote sensing data.

The purpose of this study is to explore the relationship and effect of management support on individual creativity performance by focusing on the individual learning opportunity, adaptability to change and learning motivation in Hong Kong manufacturing companies.

This study is based on survey data collection by using a respondent-driven approach from 266 employees working in Hong Kong-based manufacturing firms. The model and hypotheses were tested by employing variance-based structural equation modeling.

The findings indicate that management support has a positive effect on individual learning opportunity and creativity performance. Also, a significant positive relationship between individual creativity, performance, individual learning opportunity, adaptability to change, and learning motivation has been yielded. The management support has an overall positive link with all variables directly and indirectly.

Top management can foster employee creativity by supporting and providing learning opportunities and motivating employees to develop adaptive capability at an individual level.

An empirical study of how management support can foster individual creativity performance and individual learning opportunity. This study is one of the first to examine the positive relationship between management support and individual creativity by validating a purposed model, especially in the context of the Hong Kong manufacturing industry.

The purpose of this paper is to investigate the conceptual and empirical issues related to sexual harassment (SH) in a police department in Taiwan.

Survey data were collected. Through the analysis, the paper proposes that SH can be better divided into two subcategories: quid pro quo and hostile work environment harassment. Multivariate analysis is used to explore the sources of SH.

It was found that both types of SH can be better explained by work environment variables than by demographic variables, but the specific sources differ. Hostile work environment harassment is predicted by the extent to which female officers perceive or experience that deployment and transfer practices are influenced by their gender. Quid pro quo harassment is related to job barriers and dodging from work.

The two scales used in this research have captured the core of SH, but they might not fully depict the nature of SH in the police department in Taiwan. The sample was limited to the largest police department in Taiwan and it may not represent the entire police in Taiwan.

If hostile work environment and quid pro quo harassments are related to different organizational factors, it is useful for policy makers in the police to differentiate these two different types of SH and develop differential prevention and response measures.

This paper highlights the need to differentiate quid pro quo and hostile work environment harassments. It fills a gap in the literature by providing the baseline information on the prevalence of SH in one police department in Taiwan and by examining sources of SH in a profession dominated by males.

The purpose of this paper is to examine the relationships between authoritarian leadership, organizational citizenship behavior toward one’s supervisor (OCBS) and organizational deviance. The authors hypothesized curvilinear relationships between authoritarian leadership and OCBS, and between authoritarian leadership and organizational deviance.

The authors analyzed two-source survey data of 240 employee–supervisor dyads collected from seven organizations in Pakistan.

Employees exhibited most OCBS and least organizational deviance at intermediate levels of authoritarian leadership. Employees’ perception of a benevolent climate at work moderated the curvilinear relations.

The authors cannot draw causal inferences because of cross-sectional data. Furthermore, the authors’ results may be limited to cultures with high collectivism and high power distance.

This study envisions and illuminates a new avenue of curvilinear relationships among authoritarian leadership, OCBS and organizational deviance.

The two sources (employee–supervisor dyads) data collected from seven organizations supported a unique curvilinear relationship between authoritarian leadership, OCBS and organizational deviance.

Petroleum hydrocarbons are naturally occurring flammable fossil fuels used as conventional energy sources. It has carcinogenic, mutagenic properties and is considered a hazardous pollutant. Soil contaminated with petroleum hydrocarbons adversely affects the properties of soil. This paper aim to remove pollutants from the environment is an urgent need of the hour to maintain the proper functioning of soil ecosystems.

The ability of micro-organisms to degrade petroleum hydrocarbons makes it possible to use these microorganisms to clean the environment from petroleum pollution. For preparing this review, research papers and review articles related to petroleum hydrocarbons degradation by micro-organisms were collected from journals and various search engines.

Various physical and chemical methods are used for remediation of petroleum hydrocarbons contaminants. However, these methods have several disadvantages. This paper will discuss a novel understanding of petroleum hydrocarbons degradation and how micro-organisms help in petroleum-contaminated soil restoration. Bioremediation is recognized as the most environment-friendly technique for remediation. The research studies demonstrated that bacterial consortium have high biodegradation rate of petroleum hydrocarbons ranging from 83% to 89%.

Proper management of petroleum hydrocarbons pollutants from the environment is necessary because of their toxicity effects on human and environmental health.

This paper discussed novel mechanisms adopted by bacteria for biodegradation of petroleum hydrocarbons, aerobic and anaerobic biodegradation pathways, genes and enzymes involved in petroleum hydrocarbons biodegradation.
