Mashup tools are platforms that enable end users to combine components from multiple sources and thus create, deploy, and share their own web applications. The aim of this paper is to present and discuss the findings of two empirical studies on evaluation of mashup tools by means of subjective and objective measuring instruments. In the first study, data were gathered with the employment of SUS...

Foot-ground interfaces exist in many different forms. Frequently the interface is a shoe or floor mat, and sometimes it is a carpet-like material, such as an Astroturf, providing specific biomechanical characteristics to help one perform effectively. Hence these interfaces can play an important role in improving functionality or performance, preventing injury, and reducing discomfort. Human mov...

Several studies have investigated associations between socioeconomic status (SES) and indicators of children's physiological and cognitive self-regulation. Although objective measures of family SES may be good proxies for families' experiences of disadvantage, less is known about subjective aspects of families' experiences. We hypothesize that subjective social status (SSS) and perceived stress...

Subjective happiness has been assessed in the U.S. since 1972 by the General Social Survey (GSS). We examine trends in happiness over the last 25 years, and investigate the objective causes of these trends.

Theoretical interpretation of what one observes requires the theory to indicate what is expected, which will commonly depend on where, and particularly when, ...

OBJECTIVE To investigate the relationship between objective and subjective torsion in patients with cyclovertical strabismus and determine whether objective torsion differs according to which eye is fixing. DESIGN A prospective evaluation of tests of objective and subjective torsion. PARTICIPANTS Thirty-six patients with various types of cyclovertical strabismus. METHODS Subjective torsio...
