To contribute to achieving the Sustainable Development Goals, this study aims to explore how to encourage innovative green behaviors among college students and the mechanisms behind the formation of green innovation behavior. Specifically, this study examines the influences of schools, mentors and college students themselves.

A multilevel, multisource study involving 261 students from 51 groups generally supported this study’s predictions.

Proenvironmental and responsible mentors significantly predicted innovative green behavior among college students. In addition, creative motivation mediated the logical chain among green intellectual capital, emotional intelligence and green innovation behavior.

The study findings offer new insights into the conditions required for college students to engage in green innovation. In addition, they provide practical implications for cultivating green innovation among college students.

The authors proposed and tested a multilevel theory based on the ability–motivation–opportunity framework. In this model, proenvironmental and responsible mentors, green intellectual capital and emotional intelligence triggered innovative green behavior among college students through creative motivation.

Because of the logic delay in the converter, the minimum turn on time of the switch is influenced by the constant time. When the inductor current gets to the threshold of the chip, the control signal will delay for a period. This makes the inductor current rising with the increasing of the clock and leads to the load current out of control. Thus, this paper aims to design an oscillator with a variable frequency protection function.

This paper presents an oscillator with the reducing frequency applied in the DC-DC converter. When the converter works normally, the operating frequency of the oscillator is 1.5 MHz. So the inductor current has enough time to decay and prevent the power transistor damaging. After the abnormal condition, the converter returns to the normal operating mode automatically.

Based on 0.5 µm CMOS process, simulated by the HSPICE, the simulation results shows that the frequency of the oscillator linearly decreases from 1.5 MHz to 380 KHz when the feedback voltage less than 0.2 V. The maximum deviation of the oscillator frequency is only 6 per cent from −50°C to 125°C within the power supply voltage of 2.7-5.5 V.

When the light load occurs at the output stage, the oscillator frequency will decrease as the load voltage drops. The test results shows that when the circuit works in the normal condition, the oscillator frequency is 1.5 MHz. When the load decreased, the operating frequency is dropped dramatically.

To achieve the dual goals of decarbonization and food security, this paper examines China's carbon footprint reduction in 2050 based on current mitigation strategies.

Considering publications as featured evidence, this study develops an investigation of agricultural decarbonization in China. First, the authors summarize the mitigation strategies for agricultural greenhouse gas (GHG) emissions in the existing literature. Second, the authors demonstrate the domestic food production target in 2050 and the projection target's projected life-cycle-based GHG emissions at the commodity level. Lastly, the authors forecast China's emission removal in the agri-food sector in 2050 concerning current mitigation strategies and commodity productions. The authors highlight the extent to which each mitigation strategy contributes to decarbonization in China.

Practices promoting sustainable development in the agri-food sector significantly contribute to GHG emission removal. The authors find mitigation strategies inhibiting future GHG emissions in the agri-food sector comprise improving nitrogen use efficiency in fertilizers, changing food consumption structure, manure management, cover crops, food waste reduction, dietary change of livestock and covered manure. A 10% improvement in nitrogen use efficiency contributes to 5.03% of GHG emission removal in the agri-food sector by 2050. Reducing food waste and food processing from 30% to 20% would inhibit 1.59% of the total GHG emissions in the agri-food sector.

This study contributes to policy discussions by accounting for agricultural direct and indirect emission components and assessing the dynamic changes in those related components. This study also extends existing research by forecasting to which extent the decarbonization effects implemented by current mitigation strategies can be achieved while meeting 2050 food security in China.

The dissemination of misleading and false information through media can jeopardize a company’s reputation, thus posing a threat to its stock and performance. Institutional investors are known to influence capital markets. Therefore, this paper investigates whether institutional investors engage in shaping the media sentiment stock nexus, stabilize company stocks and enhance performance.

We first investigate the effect of media sentiment on market reactions by using panel regression models. To examine the role of institutional investors, we design a quasi-experiment by exploiting the Financial Crisis of 2008 and go further by examining the heterogeneity across levels of institutional ownership. Due to risk-averse, investors may respond asymmetrically to pessimistic and positive sentiment. Accordingly, we split the sample into two sub-types, good news and bad news, based on keywords representing positive or negative content.

We find supportive evidence that institutional investors have impacts on how the markets react to media news, and the impacts are heterogeneous in the face of bad and good news. We conjecture that institutional investors act as a stabilizer of stock prices through media sentiment management.

This paper confirms the distinctive effects of institutional investors on capital markets, and uncovers the behind-the-scenes intervention and possible causal link running from institutional investors to media sentiment management. It contributes to the broad field of institutional investors' behavior, media news involvement in capital markets and market efficiency.

The movie substitutes such as home cinema, video on demand (VOD), and plasma televisions leaded to a declining attendance of patrons to movie theatres, which urged the invention of IMAX theatre to call movie lovers back to cinemas. Many cinemas plan to renovate their regular digital theatre auditoriums into IMAX theatre auditoriums, but there lack of study for built environmental variations between regular and IMAX theatres. Through the combination of a questionnaire survey and a case study on a leading cinema company in Malaysia, the Tanjong Golden Village Cinemas (TGV), this paper aims to identify the structural and architectural differences between regular digital theatre auditorium and IMAX theatre auditorium in the perspectives of acoustic and visual experiences. The most significant factor influencing the satisfaction of visualization in IMAX is “immersive of picture” followed by “sharpness of colour” and “feels as part of the picture”. The most significant indicators for audio experience in IMAX is “direction of object”, which enable an audience to trace the direction and position of an object on the screen without looking at it. The built environmental variations between regular and IMAX theatres in terms of screen, camera and projection methods, seating, architectural layout, wall design, and sound system arrangement were thoroughly compared in the case study.

Port competition attracted much scholarly attention in Northwest Europe during the 1980s. Following the rise of powerful economies in East Asia, particularly during the 1980s and 1990s, port competition has become an important phenomenon with the top five container ports in the world being located in the region. This paper aims to overview major port competition issues and outlines and analyzes the main alternative methodologies that researchers have employed to address them, referring to 70 items, mostly papers but including a few books and reports

Many companies invest in innovations because of the inherent benefits, and research on innovation has increased over the year. However, the vast majority of research papers deals with purely technical matters. There seem to be growing concerns over ethical issues in adopting innovations in the construction industry. This extant review of literature aims to analyse the interrelations between the concepts of ethics and innovations in construction research to understand the advances of current scientific production and future lines of research.

Thus, this work presents a bibliometric analysis covering articles obtained from the Web of Science Core Collection Database published between 1995 and May 2021. A sample size of 5,786 research papers relevant to the study was evaluated using VOSviewer software.

The results of the analysis shed light on the evolution of the connection between the two concepts. The study highlighted Heng Li as the most productive author. The country with the most publications and citations is China. The most productive institution is the Hong Kong Polytechnic University. The results revealed a limited intellectual exchange and lack of cohesion characterising the two concepts (ethics and innovation), resulting in a situation whereby innovation-related researchers tend to follow personal trajectories in isolation from ethics-related researchers in the construction field.

This is probably the most comprehensive scientometric analysis ever conducted to examine the theoretical relationship between ethics and innovation in construction. This study adds to the so far limited knowledge in the field and provides insights for future research. Overall, this review may spur future research on dyad investigation of ethics and innovative related themes in construction such as ethics and sustainability, ethics and sensor-based technology and ethics and innovative safety approach.

This paper explores the characteristics and practices of principals in four successful Singapore primary schools.

Multiple perspective case studies were used which included semi-structured interviews with the principal, teaching and non-teaching staff, students, parents and school board members in each school.

The principals were found to have contributed significantly to the success of their schools. Their leadership was underpinned by their personal qualities, beliefs and values, which guided their practices. The four principals were highly successful in improving school capacity through redesigning school structures, particularly those that facilitate improvement in the work of teachers. They enhanced the professional capacity of the teaching and non-teaching staff through professional development programmes and the development of future leaders. The principals also established meaningful partnerships with stakeholders inside and outside the school community. Each of the principals described how their leadership was built upon the legacy of previous principals at their schools.

As part of a larger project, the International Successful School Principalship Project (ISSPP), this research adds an important Asian context to the literature on successful school leadership. A 6E model - Educate, Envision, Energize, Engage, Enable and Embrace - was developed to describe how principals led their schools to achieve educational excellence.

Cooperation in agriculture and agricultural products trade is a new driving force for Sino-Russian cooperation in economy and trade in recent years. Driven by the interests and needs of both countries, a Free Trade Zone (FTZ) on the Chinese territory facing Russia, the Heilongjiang FTZ, has been established, and agricultural cooperation has attracted much attention within the FTZ framework. This chapter aims to analyze and explain the prospects of Sino-Russian agricultural cooperation under the framework of the Heilongjiang FTZ based on the current situations of cooperation. The author concludes that the Heihe and Suifenhe Areas in Heilongjiang FTZ are developed with a focus on Sino-Russian agricultural cooperation. This chapter is innovative because it combined the traditional research perspective on Sino-Russian agricultural cooperation with that under the FTZ framework. The author thinks that to facilitate the cooperation between the two countries in agriculture under the FTZ, the two governments must cooperate more extensively. Besides, they need to discuss the establishment of infrastructures like a joint agricultural product R&D centre and a digital development centre for agriculture. Meanwhile, the schemes of dispute settlement and risk-sharing should be addressed as well.

The purpose of this paper is to explore Airbnb’s inherent network structure emerging from transactions between hosts and guests and provide comprehensive background information on the underlying data basis.

The analysis is based on actual Airbnb data from 16 major US cities (Asheville, Austin, Boston, Chicago, Denver, Los Angeles, Nashville, New Orleans, New York City, Oakland, Portland, San Diego, San Francisco, Santa Cruz, Seattle and Washington DC), available at InsideAirbnb.com, comprising a total of 135 thousand listings and 2.7 million transactions. The data are transformed into a graph and analyzed from a network perspective.

The web of host–guest connections on Airbnb represents a omniferous graph, that is, connecting virtually all users via relatively short distances. Hosts and guests differ markedly with regard to degree distribution. Overall, 98 per cent of all transactions represent first-time encounters.

This paper provides first insights into the very fabric of host–guest interactions on Airbnb from a macroscopic perspective. The platform’s network topology may be leveraged as a resource for trust-building between users. Moreover, platform operators may use network analyses to gain deeper insights into their user base. These may in turn be used to identify determinants of side-switching, deter users from platform circumvention or for churn prevention.

Platform ecosystems continue to expand and gain increasing economic, social and societal importance. For C2C platforms with two compartmentalized and decentral market sides (i.e. many individual providers and many individual consumers), the emerging transactional network structure has, thus, far experience almost no research attention. This analysis of Airbnb’s web of host–guest connections reveals a topology some archetypical social network properties (e.g. short distances). This structure and the knowledge about users’ positions therein yields viable cues for trust-building as well as a valuable resource for (platform) business analytics.
