Today, drones (i.e., autonomous or remotely piloted flying machines) are being built and start to be used. Military operations using drones are now becoming better established. However, drones are still under-regulated in the civilian world. Main questions are about safety and security. Therefore, drone operations have to be seriously considered by commercial and general aviation regulatory ins...

The influential papers on the effect of credit constraints on growth and international trade (Rajan and Zingales, 1998; Manova, 2013) tend to assume that asset tangibility and the share of external borrowing are exogenous industry characteristics, which are timeand country-invariant. In the finance literature, however, the share of external borrowing is viewed as endogenous and dependent on the...

In collaborative modelling, a group of stakeholders construct a shared graphical representation of a system. In practice, not all stakeholders may fully comprehend the modelling language. This may reduce their participation, which results in reduced model quality. Our goal is to investigate which features of modelling languages help stakeholders contribute to collaborative modelling tasks. Earl...

As IT becomes highly efficient, ICT (information and communications technology) began to evolve into a direction to maximize convenience or tangibility. ICT, especially, develops into a direction for the qualitative improvement of emotion-based personalization and tangibility maximization. Actually, studies on the emotion model to express human emotion quantitatively and structurally for the qu...

BraiWe characters and letters were presented to the senses of touch and vision of sighted observers. The optical stimuli were subjected to low-pass spatial filtering to the degree that visual spatial resolution closely matched tactile spatial resolution (re the size of characters presented). In one experiment, three sets of braille characters and five sets of Roman letters, varying in typograph...

The popularity of social network services and their extension in mobile environments raises privacy and usability issues. Indeed, it is difficult to establish a link between real locations or situations and virtual information such as a user’s location or context. NFCSocial is a mobile application which tackles with this difficulty. By using proximity sensor technologies such as NFC to interact...

This study aims to compare quality gap of educational services at Zahedan University of Medical Sciences from students and faculties viewpoints. In a cross-sectional study, survey questionnaire was completed by two distinct groups of respondents- 230 faculty members and 384 students. Mass majority of the both groups declared there was negative gap in each of the five dimensions. Mean quality ga...

Results: The analysis finds that cash flow sensitivity is a valid measure of financial constraints in the Indian manufacturing sector. Results according to splitting criteria found that investment decisions of standalone firms are more sensitive to cash flow than group affiliated firms. Further, splitting the firms according to market capitalization and tangible net worth reveals a higher degre...

Using an intertemporal model of investment decisions under financing constraints we show that the Euler equation approach can be used to identify the effect of financing constraints on investment returns even when the premium on external financing does not change over time. This result is made possible by the introduction of a tangibility constraint to a commonly used dynamic optimization model...
