Following Blumenthal et al. 1] and Piran et al. 2] I discuss a simple model for the gravitational formation of voids. This model enables us to estimate the primordial perturbation required on the scale of voids. A comparison of this condition with the constraints on the spectrum of uctuations derived from CMBR observations reveals that gravitational growth of large voids require more power on t...

abstraCt An integrative model explaining intentions to use an information technology is proposed. The primary objective is to obtain a clearer picture of how intentions are formed, and draws on previous research such as the technology acceptance model (Davis, Bagozzi, & Warshaw, 1989) and the decomposed theory of planned behavior (Taylor & Todd, 1995a). The conceptual model was tested using que...

The present study explores hemispheric differences in verb and verb-derived noun production in terms of the impact of various picture and word characteristics on visual field reaction time variance. The unique contribution of predictors has been interpreted as activation of a corresponding property, as indication of a stage of picture processing and as activation of a corresponding mechanism/sy...

resilience thinking in urban environment has been recently proposed as an effective measure to realize the objectives of sustainable development, minimize uncertainties and non linear interactions. this concept, in the context of modern urban ecology makes it possible to integrate natural and human factors and in urban systems and understanding the interactions between them, expanding sustainab...

background to assess maternal confidence in her ability to cope with labor, a measure of childbirth self efficacy is necessary. objectives this paper aims to assess the cultural adaptation and psychometric testing of the short form of childbirth self-efficacy inventory among iranian pregnant women. patients and methods in this descriptive-methodological study, we investigated 383 iranian pregna...

In this thesis the problem of conceptual engineering design and the possible use of adaptive search techniques and other machine based methods therein are explored. For the multi–objective optimisation (MOO) within conceptual design problem, genetic algorithms (GA) adapted to MOO are used and various techniques explored: weighted sums, lexicographic order, Pareto method with and without ranking...

This article deals with the peculiarities of mechanisms providing formation of semantics of compound words from the perspective of the cognitive approach. More to the point, it is a question of conceptual derivation, where meaning formation of compound words is carried out by the interaction of its component conceptual structures. The author has researched the main means which take part in the ...
