In China, 260 million people migrate to cities to realize their urban dreams. Despite that these migrants play an important role in the rapid urbanization process, many of them fail to settle down and eventually leave the city. The integration process of migrants thus raises an important issue for scholars and policymakers. In this paper, we use Shanghai as an example to investigate migrants’ b...

The purpose of this paper is to develop a general framework for the prediction of complex multiscale phenomena and to illustrate this framework through comparison to two examples of current interest to the authors. Prediction involves a two step process of inverse prediction to describe the system, given observations of its behavior, and forward prediction, to specify system behavior, given its...

regardless of severity, earlier intervention to correct hearing loss in children improves speech development and conversational abilities. a cross-sectional study was performed on 230 neonates who were at risk of hearing loss in tehran university of medical sciences hospitals between september 2000 and february 2002. hearing was examined before the 3rd month by auditory brainstem responses (abr...

background: stillbirth is a sensitive indicator for health care quality, living conditions and equity in a society. the aim of this study was to determine the rate and contributing factors of stillbirth at babol hospitals. methods: this cross-sectional, descriptive, analytical study was designed as an applied research, using census sampling in 2012-2013. a questionnaire was applied for data col...

in this paper, a new formula is applied for the calculation of gravity anomalies from a cylinder model representing a geological body. compared to conventional methods, this new development allows the cylinder to be freely oriented in space. 38 gravity forward models are produced each of which anomaly attributes are calculated. then a linear relationship is established between attributes and so...

In the transportation literature in general and the travel behaviour literature specifically, there is no consensus on the representation of weather in behavioural models, ranging from studies that use direct meteorological measurements, such a continuous variable for inches of rainfall or temperature, to indicator variables (which themselves are often subjectively derived) for qualitative weat...

background: industrialization and urbanization had a devastating impact on public health and caused an increase in health related morbidity and mortality. in fact, asthma is a chronic condition which is considered as one of the significant challenges of public health. in this study, we investigated the association of air pollution and weather conditions with excess emergency ward admissions of ...

The purpose of this paper is to demonstrate the validity of mesoscale numerical weather prediction modeling near the complex terrain at Aubrey Cliffs, Arizona, and to investigate the influence of the outer domain size employed on the computational results. Mesoscale Modeling v5 (MM5) was implemented to produce numerical wind data that was compared with experimental wind data. The results obtain...
