South Korea imports a large amount of agricultural and aquatic food products from China, which meets its food security. However, the import from China raises food safety questions, leading to food safety apprehension. We explored the source of the Korean consumer’s apprehension. Based on the apprehension reduction theory (ART) developed from interviews with Korean consumers in the first stage of the study, we conducted a survey to assess the social media as an indirect source of information and direct experience of the consumer in the second stage of the study. We received 504 responses, of which 1/3 of the respondents had visited China in the last year. Using FSS (Food Safety Satisfaction) as the dependent variable (1— low to 5— high), we link information from the social media vis-à-vis direct experience and made three discoveries. (a) The information quantity of social media increases the consumer’s apprehension, partially refuting the ART. (ii) FSS increased in response to information flow from the direct experience of the consumer with Chinese imported food. (c) The direct information from experience mediates the effects of indirect information (social media) on apprehension about agricultural and aquatic product imports. We made three inferences. First, information quantity and quality have separated roles in the ART. Second, social media increases the free-market style information flow, turning legitimate products to illegitimate and vice versa. Third, the collective irrationality from the information quantity needs institutional bricolage to legitimize the chaotic nature of the untamed information.

scholarly journals Remembering Election Night 2016: Subjective but not objective metrics of autobiographical memory vary with political affiliation, affective valence, and surprise

Flashbulb memories represent a unique phenomenon linking research on cognition with research on emotion, yet most studies on this phenomenon have characterized collective events that are negative and unexpected in nature. In contrast, the 2016 American election of Donald Trump was a public, culturally-shared event, eliciting extreme emotional responses that were positive for some individuals but negative for others, as well as varying levels of surprise. We longitudinally evaluated autobiographical memories for Election Night 2016 in a large online sample of Clinton supporters, Trump supporters, and third-party/non-voters over a 12-month period, in terms of both objective memory metrics (information quantity and memory consistency) and subjective memory metrics (including memory confidence, metacognition, and sensory experience). Emotional responses to the election outcome varied widely, with Clinton supporters reporting highly negative responses, Trump supporters reporting highly positive responses, and third-party/non-voters reporting mildly negative responses. Emotional intensity was enhanced in surprised versus non-surprised individuals. Relative to third-party/non-voters, Clinton and Trump supporters reported greater memory vividness, event importance, and sensory experience. Additionally, memory confidence and rehearsal differed with valence (higher confidence in Trump supporters; higher memory rehearsal in Clinton supporters). These differences in subjective experience were observed despite similar levels of information quantity and consistency across groups. This characterization of memories for surprising positive events suggests they share many of the paradoxical qualities of memories for negative events often discussed as “flashbulb memories”, and further points to important potentially distinct features of memory phenomenology for collectively-experienced, relative to personal, events.

Methodological Principles

Introduction. Some methodological provisions need to be modified according to the realities of existing practice and be verified according to the possibilities of their application in economic phenomena and processes study. Theoretical analysis of methodological principles, their comparison and generalization were used during investigation. The purpose of the paper is to study basic methodological prerequisites and principles in economic research. Results. Analyzing and summarizing the achievements of Nobel laureates, the methodological problems of limited rationality, information asymmetry and opportunistic behavior of economic agents are considered. Modern mainstream in economic research corresponds to binary paradigm of neoclassicism and neoinstitutionalism, which are based on two common elements of the “core”: methodological individualism and “economic man” conception (homo economicus). The focus of the enterprises on maximizing profitability, and households – on benefits, is an axiom of neoclassicism, which implies significant requirements for information quantity and quality. At the same time, rational choice is accompanied by situations of uncertainty and varying degrees of risk regarding such activities consequences. The advantages of the institutional direction as the closest to the real conditions of economic entities market activity are substantiated. A specific feature of neoinstitutional approach is modification of neoclassical paradigm due to preserving basic preconditions of its “core” and partial transformation of “protective shell” into more perfect, realistic principles. In economics, the most significant is methodological combination of “semi-strong” limited rationality with a “strong” form of opportunistic behavior. Conclusions. Thanks to introducing modified preconditions and methodological principles into neo-institutionalism, it became possible to improve the analysis of economics and to apply interdisciplinary research in combination with the approaches of other branches of science.

Purpose This study aims to investigate how the language used in US Title II equity crowdfunding campaign descriptions relates to campaign success. Design/methodology/approach Data on >3,200 equity offerings from 12 Title II platforms was obtained from 2013 to 2016. The aspects of the campaign descriptions that are focused on are tone and two measures of readability: information quantity – the amount of information available to the investor and information quality – the ease of understanding of the passage of text. Tobit regressions with sector-clustered standard errors are used for estimation while controlling for company-specific variables, market sentiment and platform, regional, sector and time effects. Results are robust to alternative estimation approaches. Findings Inverse U-shaped relationships exist between information quantity, information quality and tone and Title II equity crowdfunding campaign success. Overall, less is more as it appears that an intermediate level of information – quantity, quality and tone – is optimal in terms of being a factor that contributes to equity crowdfunding campaign success. Originality/value Extends the use of textual analysis to the equity crowdfunding environment in the USA where such analysis is lacking and provides empirical evidence that the language used (e.g. sentiment) in US Title II equity-based crowdfunding campaign descriptions does influence campaign success. It provides empirical evidence of and extends the concept of information overload to the entrepreneurial finance sub-field and indicates tone may be an additional information attribute to consider in this context as contributing to overload.

The shortest path between the start node and end node plays an important role in city’s road traffic network analysis system. The basic ant colony system algorithm which is a novel simulated evolutionary algorithm is studied to solve the shortest path problem. But the basic ant colony system algorithm is easy to run into the local optimum solution for shortest path. In order to solve the problem, the improved ant colony system algorithm is proposed. The improvement methods for selection strategy, local search, and information quantity modification of basic ant colony system are discussed in detail. The experiments are done in Beijing road network in China. The results of experiments show that comparing with the basic ant colony algorithm, the improved algorithm can easily converge at the global optimum for the shortest path.
