Mobile five senses augmented reality system: technology acceptance study

Publication . Rodrigues, João; Ramos, Celia; Pereira, Joao A. R.; Sardo, Joao D. P.; Cardoso, Pedro

The application of the most recent technologies is fundamental to add value to tourism experiences, as well as in other economic sectors. Mobile Five Senses Augmented Reality (M5SAR) system is a mobile guide instrument for cultural, historical, and museum events. In order to realize the proclaimed five senses, the system has two main modules: a (i) mobile application which deals mainly with the senses of sight and hearing, using for that the mobile device camera to recognize and track on-the-fly (museum's) objects and give related information about them; and a (ii) portable device capable of enhancing the augmented reality (AR) experience to the full five senses through the stimulus of touch, taste, and smell, by associating itself to the users' smartphone or tablet. This paper briefly presents the system's architecture but, the main focus is on the analysis of the users' acceptance for this technology, namely the AR (software) application, and its integration with the (hardware) device to achieve the five senses AR. Results show that social influence, effort expectancy, and facilitating conditions are the key constructs that drive the users to accept and M5SAR's technology.

The role of social and technical excludability for the success of impure public good and common pool agreements

Publication . Finus, Michael; Schneider, Raoul; Pintassilgo, Pedro

We argue that international fisheries are a prime example to study the incentive structure of forming impure public good and common pool agreements. We consider a fully integrated multiple zone model, in which zones are linked through density-dependent migration. The incentive to accede to Regional Fishery Management Organizations (RFMOs) is related to multiple characteristics. Firstly, the relative patch sizes of the high seas, which is the internationally (publicly) accessible domain, compared to exclusive economic zones, which are state-owned (privately owned). This can be related to the degree of socially constructed excludability. Secondly, the intensity of fish migration between various zones, which can be related to the degree of technical excludability. Thirdly, the growth rate of the resource, which can be interpreted as the degree of rivalry, with a low (high) degree of rivalry approximating public good (common pool) features. We show that, generally, excludability reduces free-riding incentives but also the need for cooperation, a variant of the "paradox of cooperation". Moreover, we show that the benefit-cost duality between public goods and common pool resources generally holds except for some extreme parameter values for which a low degree of rivalry fosters the success of cooperation. Finally, through a variation of the diffusion matrix, we can also analyze a closed as well as a sink-source system. (C) 2019 Elsevier B.V. All rights reserved.

Business-Bankruptcy After the BAPCPA: Evidence From the Stock Market

Publication . Coelho, Luís

Little is known about how the Bankruptcy Abuse Prevention and Consumer Protection Act (BAPCPA) affects the business-bankruptcy landscape in the United States. This study addresses this gap in the literature by investigating the stock price dynamics of firms filing for Chapter 11 under both the 1978 Bankruptcy Act and the BAPCPA. Results show that, on average, shareholders of firms filing for Chapter 11 under the new Act lose significantly more both at and shortly after the event date than their 1978 counterparts do. Given the economic magnitude and robustness of these findings, this article's empirical evidence suggests the market perceives the BAPCPA to be more creditor-friendly than its predecessor is.
