One approach to user experience (UX) is phenomenology, but there are no well-defined methods for how to conduct UX research using phenomenology, especially not in a professional design practice. One well-defined approach developed in psychology is Interpretative Phenomenological Analysis (IPA), which in this paper is adapted to professional UX research practice. The adaptation is put to test in...

The Allee effect means reduction in individual fitness at low population densities. There are many discrete-time population models with an Allee effect in the literature, but most of them are phenomenological. Recently, Geritz and Kisdi [2004. On the mechanistic underpinning of discrete-time population models with complex dynamics. J. Theor. Biol. 228, 261-269] presented a mechanistic underpinn...

background: cerebral palsy (cp) describes a group of disorders regarding the development of movement and posture, which causes limitations in activity. in fact, it is attributed to non-progressive disturbances that occur during brain development in fetus or infant. cp disorders may accompany by speech, auditory, visual abnormality, seizure, learning disorder, mental retardation and etc. due to ...

abstract aim and background: adoption is a subject with prolix antecedent in historical society and culture. child acceptation affects on partner and kinfolk relation; so the family experience recognition help nurse to have deep knowledge about family relation. method and materials: in this phenomenological qualitative study, participants were 15 family with adopted child in shahrekord, iran. t...

We study the effects of polymer additives on turbulence generated by the ubiquitous Rayleigh-Taylor instability. Numerical simulations of complete viscoelastic models provide clear evidence that the heat transport is enhanced up to 50% with respect to the Newtonian case. This phenomenon is accompanied by a speed-up of the mixing layer growth. We give a phenomenological interpretation of these r...

A nonlinear self-adjoint operator on a two-dimensional Hilbert space is constructed to force a quantum state, composed of two orthogonal states through linear superposition, into one of these two alternatives (reduction). Associated with this is a bifurcation-process of a collapsing statevector at the site of two detectors: since there are no discernible experiments for nonunitary schemes of qu...

A phenomenological approach was used to describe the lived experience of disability of a woman who sustained a head injury 21 years ago. Data were collected through 11 face-to-face interviews and 72 e-mail messages over the period of 11 weeks. An iterative, fluid process of questioning, information-giving, analysis, and verification was characteristic of the whole study, alternating between ana...

We discuss neuroscientific and phenomenological arguments in support of Millikan’s thesis. Then we consider invariance as a unifying theme in perceptual and conceptual tracking, and how invariants may be extracted from the environment. Finally we consider some wider implications of Millikan’s nondescriptionist approach to language, with especial application to color terms. Since I am in substan...
