Construction vs. Development: Polarizing Models of Human Gestation

Construction vs. development: polarizing models of human gestation.

This essay argues that the polarization of our public debate over embryo-destructive research may be due, to a large extent, not to different valuations of individual human life but to different conceptions of the process of gestation, with one group treating the process as a making or construction and the other treating it as a development. These two incompatible models of reproduction are sho...

Models of EFL Learners’ Vocabulary Development: Spreading Activation vs. Hierarchical Network Model

Semantic network approaches view organization or representation of internal lexicon in the form of either spreading or hierarchical system identified, respectively, as Spreading Activation Model (SAM) and Hi- erarchical Network Model (HNM). However, the validity of either model is amongst the intact issues in the literature which can be studied through basing the instruction compatible wi...

Growth and development of human adipose tissue during early gestation.

805 normal-for-age human embryos and fetuses were used to study early prenatal fat development. The investigation included observations on stages of fat morphogenesis at the light microscopic level and computerized image analyses of fat lobule size and number. The buccal fat pad was selected as a model system for the analyses. Fat tissue differentiates between the 14th and the 16th weeks: there...

Unsupervised construction of human body models

Unsupervised learning of a generalizable model of the visual appearance of humans from video data is of major importance for computing systems interacting naturally with their users and others. We propose a step towards automatic behavior understanding by making the posture estimation cycle more autonomous. The system extracts coherent motion from moving upper bodies and autonomously decides ab...
