Traders' networks of interactions and structural properties of financial markets: an agent-based approach
No full textAn information-based multiasset artificial stock market characterized by different types of stocks and populated by heterogeneous agents is presented and studied so as to determine the influences of agents' networks on the market's structure. Agents are organized in networks that are responsible for the formation of the sentiments of the agents. In themarket, agents trade risky assets in exchange for cash and share their sentiments by means of interactions that are determined by sparsely connected graphs. A central market maker (clearing house mechanism) determines the price process for each stock at the intersection of the demand and the supply curves. A set of market's structure indicators based on the main single-assets and multiassets stylized facts have been defined, in order to study the effects of the agents' networks. Results point out an intrinsic structural resilience of the stock market. In fact, the network is necessary in order to archive the ability to reproduce the main stylized facts, but also the market has some characteristics that are independent from the network and depend on the finiteness of traders' wealth
An industry and public research organization joint effort for ITER construction: evaluating the impact
No full textParticipation in Big Science projects, such as ITER, and the exchange of technology and knowledge with science-based partners are fruitful environments for industry. By integrating the use of quantitative and qualitative data and methods of analyses applied to a sample of Italian industries, the present work illustrates how participation in ITER, through the European Agency Fusion for Energy, allows firms to increase their financial performance, enhance their brand image, extend the network of collaborations, improve internal processes, acquire new standards and have a new vision of the company. Moreover, ITER allows for employing new people and investing in the local and regional territories. The study leads to new implications for managers and researchers in terms of new tools to be used to manage the involvement in Big Science projects and policy makers in terms of incentives to be provided, particularly for SMEs, in order to enhance knowledge dissemination and avoid business discontinuities
"Fool me once, shame on you... then, I learn." An examination of information disclosure in social networking sites
No full textThis study investigates factors that affect user decisions on which information to share, and specifically whether and how to disclose sensitive personal information, when using social networking sites (SNSs). The determinants of personal information disclosure (self-disclosure) are identified using a framework that combines communication privacy management and social penetration theories. Communication privacy management theory is applied to identify which rules guide users' sharing of personal information. Social penetration theory is used to understand personal information disclosure approaches—deep and shallow—that people employ on SNSs. Structural equation modeling was used to analyze data from 315 Facebook users who were also undergraduate students. Results show that individuals self-disclose more on SNSs when they know how to coordinate disclosure boundaries, and particularly when they have learned from prior privacy infringements. While types of relationships are important in determining self-disclosure approaches, SNSs users who have experienced a privacy breach follow different privacy coordination rules compared with those who have not experienced such an incident. Our results present an interesting twist in which the "fooled once" users show higher levels of information sharing at all levels. These users have learned their lessons and their way through privacy management options, eventually leading to a higher self-disclosure
