Online travel information value and its influence on the continuance usage intention of social media

This study tests an empirical model formulated by extending the Triandis model to examine the structural relationships among online travel information value (OTIV), near- and long-term consequences, affect, social factors, facilitating conditions, affective community commitment (ACC), current usage, and continuance usage intention (CUI) among travel-related social media users in Korea. Data were collected through an online survey using the national panel system. A total of 403 respondents were selected based on whether they had traveled at least once within the last 12 months and used at least one social media daily. Eight hypothesized relationships out of eleven were supported. Specifically, as an antecedent of the Triandis model, OTIV had a strong effect on near- and long-term consequences and affect. In addition, the effect of ACC on CUI was stronger than that for current usage. We presented theoretical and practical implications and proposed avenues for future research.     

Political Commodities and Sovereignty Management: Cigarette Smuggling across Brazil’s Southern Borders

Cigarette smuggling across Brazil’s borders with Paraguay, Uruguay and Argentina involves large amounts of merchandise and money. The public in Brazil associates this activity with images of war, contamination and other threats to state sovereignty. This article assesses the political meaning and uses of smuggling in order to challenge the assumption that smuggling threatens the sovereignty of the Brazilian state. With the help of a literature review, fieldwork at the border, interviews with practitioners, a cartographic analysis of news coverage of seizures, the tobacco production and consumption, the market and its regulation, actors, routes and networks were mapped and analysed. In the Southern Cone of South America, an integrated transborder territory emerges where tobacco is cultivated, prepared and distributed, and cigarettes are manufactured, transported, sold and smoked. These flows cross distinct legal framings and lead to an increase in danger and profit. Thus, the market is segmented between national legal products and imported cigarettes that are cheaper and illegal but easily obtainable. The concepts of political commodities understood as the acts of powerful agents who barter advantages related to their authority and sovereignty management, understood as the use of legal (state-managed) structures according to private interests at different scale levels, provide useful theoretical tools to examine the territorialisation of the cigarette smuggling and its control by the state and private agents. We conclude that tobacco production and trade, as well as cigarette smuggling, are connected via agents who use the border to build the legal market and, consequently, to increase the trade value of national tobacco. Cigarette smuggling across the state borders of the Southern Cone combines networks and places in such a way that is integrated into the legal economy and the national territories, and it does not defy state’s sovereignty.     

Time series properties of an artificial stock market

This paper presents results from an experimental computer simulated stock market. In this market artificial intelligence algorithms take on the role of traders. They make predictions about the future, and buy and sell stock as indicated by their expectations of future risk and return. Prices are set endogenously to clear the market. Time series from this market are analyzed from the standpoint of well-known empirical features in real markets. The simulated market is able to replicate several of these phenomenon, including fundamental and technical predictability, volatility persistence, and leptokurtosis. Moreover, agent behavior is shown to be consistent with these features, in that they condition on the variables that are found to be significant in the time series tests. Agents are also able to collectively learn a homogeneous rational expectations equilibrium for certain parameters giving both time series and individual forecast values consistent with the equilibrium parameter values.
