The objective of this work is to investigate correlations between the use of settings of vocal qualities and the expression of acted emotions and attitudes in speech. For the description of voice qualities, the phonetic model of description of voice quality settings developed by [1] was used. The corpus is constituted by the poem "I-Juca Pirama", interpreted by a professional actor. The percept...

Ascribing mental qualities like beliefs, intentions and wants to a machine is sometimes correct if done conservatively and is sometimes necessary to express what is known about its state. We propose some new definitional tools for this: definitions relative to an approximate theory and second order structural definitions.

System-wide properties such as reliability, availability, maintainability, security, responsiveness, adaptivity, evolvability, survivability, nomadicity, manageability, and scalability (the \ilities"), are crucial for the success of large software systems. Although these properties have been a major concern of software engineering since its inception, most of the eeort on software architecture ...

Two studies (N = 190 and N = 447) were conducted to investigate the link between living in walkable neighborhoods and satisfaction with life in a city. Additionally, we explore possible mediators of this relationship. In both studies walkability was a significant predictor of perceived quality of life in a city, and overlap between personal and communal identity (in Study 1 and Study 2) and cit...

Information System Quality (ISQ) management discipline requires a set of assessment mechanisms to evaluate external quality characteristics that are influenced by the environmental parameters and impacted by the ecosystem factors. The present paper suggests a new assessment oriented model that takes into consideration all facets of each external quality feature. The proposed model, named RatQua...

A simple model is formulated in which the growth of a consumer population is regulated by the diversity, quantity, and quality of alternate environmental resources. Equilibrium population size is dependent not only upon these resource characteristics, but upon the pattern of resource exploitation by the consumer. It is proven that in many circumstances, an exploitation pattern in which each ind...

In recent times, metal-free chemistry has received significant attention due to its inherent qualities and its potential savings in the costs of (i) reagents and (ii) environmental treatments of residues. In this context, recently developed neutral organic electron-donors have shown an ability to perform challenging reductions that are traditionally the preserve of reactive metals and metal-bas...

Alcohols and other low molecular weight oxygenates are known to be potentially valuable gasoline substitutes. While these are generally of interest in relation to the long-term need to secure future motor fuel supplies, there is a more urgent need for substitutes which will improve the octane rating of unleaded fuels. For environmental reasons, oxygenates including alcohols may be preferred to ...
