This study aims to explore the effect of competitive aggressiveness on firm performance and the moderating effect of firm 2019s ego-network structures in the international coopetition network.

From the perspective of strong cooperation of the global automobile industry in recent years, this study uses the global automobile firms in Factiva database as samples to test hypotheses using the least squares dummy variable (LSDV) model.

This study finds that there is different relationship between the number and variety of competitive actions and firm performance. In addition, ego-network structures have different coefficients for the number and variety of competitive actions.

The conclusions provide theoretical support and policy suggestions for firms to develop effective competitive strategies according to ego-network structures in the international coopetition network.

The purpose of this paper is to examine how active consumers, i.e. consumers that can inter-temporally shift their load, can influence electricity prices. As demonstrated in this paper, inter-temporal load shifting can induce negative electricity prices, a recurring phenomenon on power exchanges.

The paper presents a novel electricity-market model assuming a nodal-pricing, energy-only spot market with active consumers. This study formulates an economic equilibrium problem as a linear program and uses an established six-node case study to compare equilibrium prices of a model with inflexible demand to a model with flexible demand of active consumers.

This study illustrates that temporal coupling of hourly market clearing through load shifting of active consumers can cause negative electricity prices that are not observed in a model with ceteris paribus inflexible demand. In such situations, where compared to the case of inflexible demand more flexibility is available in the system, negative electricity prices signal lower total system costs. These negative prices result from the use of demand flexibility, which, however, cannot be fully exploited due to limited transmission capacities, respectively, loop-flow restrictions.

Literature indicates that negative electricity prices result from lacking flexibility. The results illustrate that active consumers and their additional flexibility can lead to negative electricity prices in temporally coupled markets, which in general contributes to increased system efficiency as well as increased use of renewable energy sources. These findings extend existing research in both the area of energy flexibility and causes for negative electricity prices. Therefore, policymakers should be aware of such (temporal coupling) effects and, e.g. continue to allow negative electricity prices in the future that can serve as investment signals for active consumers.

The purpose of this study is to clarify changes in people-place interrelationship and hidden layers of survivors psychological challenges in the reconstructed housing environment, the 2003 Bam and 2017 Ezgeleh-Sarpol Zahab earthquakes occurred in Iran, because perception of earthquake risk in residential dwellings and traumatic experiences during and after its occurrence are among stressful events making communities face with various spectrum of emotional and cognitive consequences. Such events shape memory “traumascapes” and cause changes in mental schemas and as a result, altering decisions and behavioral responses in long-term familiar environments. Because, in the disaster-affected communities, psychological recovery will be greatly influenced by residential experiences.

The current research was performed with a qualitative and multicase study design, and data were collected using deep and semistructured private interviews and discussions in focus groups with participation of 33 people by narrative technique.

According to findings, people are facing enduring cognitive disruptions regarding home concept and its location as a safe and secure paradigm. Findings showed that there are a considerable amount of behavioral responses and emotional consequences in the form of protective behaviors, severe sensitivity to environmental stimuli, fears, phobias in residential dwellings and disturbances in place attachments.

It is noteworthy that despite all time and place differences, the two studied communities had significant similarities in earthquake traumatic experiences and perceptions and also resulting conscious and subconscious responses.

Nowadays, universities increasingly consider reputation as a key component for improving quality and rankings. A positive reputation opens doors to added value and diverse opportunities. This paper aims to explore Middle Eastern higher education managers' perceptions of university reputation components.

Given the significance of this concept in Middle Eastern universities, a descriptive phenomenological qualitative approach is adopted to identify these key components. The study includes interviews with university managers, and data are collected through semi-structured interviews and analyzed thematically.

The findings reveal that, from the perspective of higher education managers, university reputation is influenced by four main components: university management and leadership, quality and performance, identity and image and social responsibility. These components are tailored to the context of Middle Eastern countries.

Practical implications are clearly laid out in the form of four key themes for higher education managers in Middle Eastern countries to manage reputation.

The study’s outcomes can be used as a guide for university managers in developing countries to change the situation in their favor and achieve great success in the competitive condition of universities by planning and making policies in this direction. Also, the managers of higher education in the Middle Eastern countries can take advantage of the components of this study to improve the quality and quantity of their universities and take an important step towards increasing the university’s reputation at the international level.

The purpose of this paper is to examine the dynamic of consumers' perceptions of GM food and explore whether their knowledge of GM technology is associated with a significant change.

This paper presents a meta-analysis of 156 primary studies reporting a total of 225 attitudes toward genetically modified foods. To identify the impact of consumers' knowledge of GM technology, the authors estimate multivalued treatment effects model.

The results of this study show that consumers' attitudes show a U shape during 2001–2022. That is, the rise in opposition to genetically modified foods has been reversed. In addition, this study also shows that the increase in consumers' knowledge of genetically modified technology contributes to their changes in attitude.

This paper is the first study that empirically investigates the dynamics of Chinese consumers' attitude to genetically modified foods, and shows the rise in opposition to genetically modified foods has been reversed, which has important implication for commercialization of genetically modified crops in China.

The purpose of this paper is to analyze the impact of different information source on consumer attitudes toward genetically modified food.

The data used in this study are obtained from a large-scale nationwide consumers' survey in urban China conducted by the China Center for Agricultural Policy, Peking University, in 2020. A descriptive analysis between information sources and consumer attitudes toward GM food was conducted. Based on the collected data, an econometric model on the determinants of consumer attitudes was constructed and used for analysis.

This study shows that the impact of new media is currently no different than that of traditional media, indicating that the media campaign successfully reduced the spread of rumors and misinformation regarding GM food. Moreover, this study also shows that consumers whose main information source regarding GM foods is school hold more positive feelings toward such food.

This study contributes to the existing literature by examining the impact of information source on consumer attitudes toward GM food. To reverse consumers' negative attitudes, China has launched a widespread media campaign since the first decade of the 2000s. Results of this study show that authorities' efforts to manage and surveil new media have yielded the desired outcome.
