OBJECTIVE To examine the potential moderating effects of family cohesion and acculturation on the physiological stress response (cortisol) as a predictor of preterm birth (PTB) in pregnant Mexican-American women. METHODS The sample included 470 participants; 33 had preterm births. All participants were self-identified as Mexican-American. In this cross-sectional study, family cohesion was mea...

detecting faces in cluttered backgrounds and real world has remained as an unsolved problem yet. in this paper, by using composition of some kind of independent features and one of the most common appearance based approaches, and multilayered perceptron (mlp) neural networks, not only some questions have been answered, but also the designed system achieved better performance rather than the pre...

the study of design and formation of urban space focuses on interaction of human and environment. this is an attractive subject that considers as interdisciplinary debates. thinkers of urban studies pay attention to this matter empirically and theoretically in order to provide a desirable space for human being. this research is based on the theories of urban studies and urban sociology and so o...

in this study an adaptation of halliday and hasan's (1976) description of cohesion in english was applied to the spoken narratives of typical developing children. regarding the development in grammatical cohesion, narrations of 3 groups of children 4;00 to 7;00 years of age, 5 in each age group, were analyzed and compared with each other. this research applies an experimental method.to evaluate...

This thesis is about defining participation in the context of fostering research cohesion in the field of Participatory Design. The systematic and incremental building of new knowledge is the process by which science and research is advanced. This process requires a certain type of cohesion in the way research is undertaken for new knowledge to be built from the knowledge provided by previous p...

Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...

The Statistical stream metrics developed by us are of unique type (as compared to the existing available metrics) and we propose these metrics as the solution towards software quality. Probably the managers feel they are a bit "techie." We expect that this concise research of the measures has shown that they are practical and pragmatic techniques of assuring quality. The foundation of statistic...
