Accounting Information Quality, Financing Constraints, And Company Innovation Investment Efficiency By Big Data Analysis

This paper takes the listed companies in China from 2008 to 2017 as the research sample to study the relationship between accounting information quality (AIQ) and company innovation investment efficiency. The results show that AIQ is negatively correlated with both the underinvestment and overinvestment of corporate innovation. Further, AIQ can alleviate financing constraints and reduce the lack of innovation investment; At the same time, AIQ can also alleviate the agency conflict and reduce the excessive investment in innovation. Finally, AIQ can promote the innovation investment efficiency of companies with low information environment.

A Noise Based Medical Elites Silence Model and Public Health Opinion Distortion in Social Networks

Under the impact of internet populism, internet violence, and other noises on the internet, medical elites, who have a professional background, did not intend to share their opinions on the internet. Thus, misinformation about health is increasingly prevalent. We roughly divided the users in social networks into ordinary users, medical elites, and super-influencers. In this paper, we propose a communication model of health information based on the improved Hegselmann-Krause (H-K) model. By conducting MATLAB-based simulation, the experimental results showed that network noise was an important factor that interfered with opinion propagation regarding health. The louder the noise is, the harder it is for health opinions within a group to reach a consensus. But even in a noisy environment, super-influencers could influence the overall cognition on public health in the social network fundamentally. When the super-influencers held positive opinions in public health, the medical elite keeping silent had a noise-tolerant effect on opinion communication in public health, and vice versa. Thus, three factors concerning noise control, the free information release of medical elites, and the positive position of super-influence are very important to form a virtuous information environment for public health.

Branding in libraries: Identifying key requirements and dimensions to provide a conceptual model

The purpose of this review is to explore factors affecting brand building in libraries. Based on the nine steps of the National Health Service (NHS) center for reviews and dissemination, articles on the subject of library branding were searched in nine Iranian databases and seven international databases. The search period includes all date range of databases until 7–22 January 2021. The results were assessed for quality and 44 English articles and 3 Persian articles were selected for further analysis. Factors in promoting libraries brand building fall five categories. They include library architecture, library information resources and services, librarians’ personal branding, marketing, and library management. Inhibiting factors in libraries brand building have two final categories including internal and external inhibiting factors to brand building. Internal inhibitors covered branding costs, lead-time for branding, effort for branding and its management, the difficulty of strategic brand planning, and library staff unpreparedness. External inhibitors covered the difficulties of branding in the digital age and the economic situation of the country. If libraries manage their brand and move toward rebranding in line with the new information environment, they will be able to survive in today’s competitive world and build their true value in relationship with users.

PERSEPSI TENTANG RISIKO BREAKTHROUGH INFECTION COVID-19 DALAM LINGKUNGAN HEALTH RISK MESSAGES

The Covid-19 vaccination rate continues to increase, it is important to pay attention to the possibility of a breakthrough infection, which is a viral infection that occurs after a person has been vaccinated. This is a case that is expected to occur in some of those who have received the vaccine, as no vaccine for any disease is 100 percent effective. During the time of living in this period of the Covid-19 pandemic, people are always exposed to information about the dangers or threats of exposure to the virus, known as health risk messages. This study was conducted to explain how a number of individual characteristics in the health risk message information environment correlate to their attitudes towards the risk of exposing Covid-19. This online survey of people who have received the Covid-19 vaccine found that several variables related to lifestyle and disease history were correlated to perceptions of the risk of exposure to Covid-19. It also confirms that there is a positive correlation between awareness of the amount of risk an individual has and perceptions of the risk of exposing Covid-19.

Ecology of Communication: the toxicity factors in media

The paper raises the problem of media ecology. The concept of media ecology is considered from the standpoint of post-nonclassical rationality: the object of research is viewed as a system that unifies communicants, their communities and the information environment within the framework of ongoing interactions, which, in turn, affect all elements of the ecosystem. The authors analyze socio-cultural changes caused by media influence and give the interpretation of the manifestations of media toxicity through five components of communication (toxicity factors): (1) subject; (2) sign code; (3) content; (4) method and (5) discourse background. The experimental base of the research is represented by a lexical-semantic analysis of materials from print and electronic media and students' essays (n>300), an associative experiment conducted with students of the direction of training “Advertising and public relations” (Moscow and St. Petersburg, n> 200). At the end the authors share the experience of holding a scientific conference dedicated to the discussed problem as an optimal format for involving students in the problems of the ecology of media communication.

Creating an Information Environment for Construction Projects

Aim. The presented study aims to create a unified information environment for all participants of construction project implementation and to monitor key indicators of construction during its implementation.Tasks. The authors develop a methodological approach to substantiate a unified information environment for the implementation of capital construction projects; develop modules of the information environment that reflect the processes of designing a facility and managing costs at all stages of its life cycle. Methods. This study uses the methods of analysis and synthesis, graphical modeling, expert and comparative assessments, methods of pricing in construction.Results. An information environment for the implementation of capital construction projects is developed. Its major modules reflect the processes of designing and constructing a facility and managing costs at all stages of its life cycle.Conclusions. Introduction of the proposed information environment for managing construction costs at the enterprise level with an integrated design module based on information modeling technologies will improve the efficiency of interaction between the participants of the investment and construction process and will provide a unified cost management algorithm in the context of the active digitalization of the industry.

Interval basic uncertain information and related aggregations in decision making

The recently proposed basic uncertain information can directly present numerical uncertainties for given real values, but it cannot handle given interval values which themselves also have uncertainties. Against this background, this work proposes the concept of interval basic uncertain information which serves as a generalization of basic uncertain information and involves two types of uncertainties. We analyze some basic operations, weighted arithmetic mean and preference transformation for interval basic uncertain information. The Rule-based decisions and the comprehensive certainty of interval basic uncertain information are also discussed. An illustrative example of multi-source multi-criteria evaluation under interval basic uncertain information environment is presented.
