Analysis of residential choice behavior at community scale

The complex problems shared by many cities throughout Japan are evidence of the impacts of land use plans that have been poorly designed and managed. Most of the existing plans in Japan have focused on the metropolitan areas but nowadays the physical layout or land use of communities is fundamental to sustainability. Community sustainability requires a transition from poorly-managed large-scale plans to land use planning practices at the community scale that maintain efficient infrastructures, and ensure close-knit neighborhoods and a sense of community. This paper provides a scheme for discussing the residential choice of people at the community scale in a local city in Japan in order to help local communities or local authorities concerned with suitable land use planning. First, this paper gives the key principles of residential choice behavior through the statistical analysis of the revealed preference of people who actually made the decision to choose the location of their new residence. Some interesting results are a bigger correlation than expected between the location of residence and the place of work, and a strong attachment of movers to their old communities. The latter half of this paper describes a modeling process for specifying the residential choice at the community scale. The discrete choice model adopted in the present study is a conventional disaggregate logit model that is capable of representing complicated individual choice behavior while they are changing their place of residence.

On the Ground Effect of Static Circular Peripheral Jet

As a part of general investigations into Ground Effect Machine (GEM), a study has been made related to the jet flow and the base pressure of a circular peripheral jet in proximity to the ground. Approximate theories have been derived by using simple assumptions to obtain the relations between the jet flow or the base pressure and the hover height above the ground. The theoretical results are compared with the experiment of a circular peripheral jet model GEM. The agreement between those results are not so excellent, but it is supposed that the reason depends mainly on the viscous effects which are neglected in this analysis

Spatial structure and prediction of Land use change considering development projects in urban promotion districts

n this paper, the actual conditions and the change structure of land use by using mesh data are studied in urban promotion area in a local hub city of Fukuoka, Japan. Firstly, all meshes are classified into 15 patterns based on distribution of land use. Then, transition probability models are made out based on the change of these 15 patterns. The Change structure of land use in an area depends on whether development projects are carried out or not. Therefore, all of the meshes are divided into two groups, and different transition probability models are proposed. Finally, a prediction method of land use is proposed under the consideration of the changing structure of meshes. Though our proposed approach is a macroscopic forecasting method of land use, it is useful to evaluate the effects of urban policies for development projects.

Evaluation of City Planning Road Development Measures by Microscopic Traffic Simulation

This study was made on the development plan of Kawahara Avenue, a road project authorized in city planning of Miyazaki City in Japan. The Kawahara Avenue development is planned along the Oyodo River. The land use of the area along the route comprises the tourist hotel zone, residential zone, and industrial zone. The Kawahara Avenue planning, unlike most other road development plans in Japan, requires much more than simply providing for the smooth flow of traffic. In the tourist hotel zone where the leading Miyazaki City hotels are located, the image and impression the tourists may have about the city is an important consideration. Therefore, the city government intends that this section of the road should not have excessive traffic. In the residential zone, the existing road network consists of narrow streets with no sidewalks. In addition to the sidewalks to be built, Kawahara Avenue is expected to handle a great deal of the traffic passing the residential district. This should help meet the goal in providing a safe environment for the pedestrians in other narrow streets without sidewalks. Under the circumstances as stated above, the planning has faced significant constraints in land purchasing involving forced move-out in the result of financial problems and coordination of the views between the city administration and the residents in the vicinity. The purpose of this research is to study under the given constraints what would be the most appropriate plan for the development of Kawahara Avenue. First, a traffic monitoring survey was conducted in the subject districts to compile Origin-Destination (OD) data of traffic flow in the districts. Then, the road network of the subject districts and traffic signal phase data were digitized to carry out microscopic traffic simulation and checked for reproduction accuracy of the current situation. The results confirmed that simulation reproduces the traffic conditions of the districts with sufficient precision. Furthermore, we prepared several hypothetical proposals for the road development and evaluated with the same simulation system as to how the traffic situations would be had those proposals been implemented. As a result it was demonstrated that the original goals can be achieved by developing the road within the given constraints.

Flow Pattern and Switching Mechanism in a Wall Attachment Type Fluid Amplifier

An experimental investigation has been performed to determine the steady-state pattern and the switching mechanism of the airflow in a wall attachment type fluid amplifier. With the experimental results, it is shown that the jet flow is considerably affected by the splitter distance and the step height of the device, and switching action of the flow caused by a step control jet, i.e. the switching time and the critical velocity range of control jet, is determined. By using some simple assumptions, approximate calculation have been carried out to obtain the relations between the switching time and the step control jet flow, and are compared with the experimental results

G‐CSF‐dependent neutrophil differentiation requires downregulation of MAPK activities through the Gab2 signaling pathway

Granulocyte colony‐stimulating factor (G‐CSF) stimulation of myeloid cells induced tyrosine‐phosphorylation of cellular proteins. One of the tyrosine‐phosphorylated proteins was found to be a scaffold protein, Grb2‐associated binding protein 2 (Gab2). Another member of Gab family protein, Gab3, was exogenously overexpressed in neutrophil progenitor cells to make the Gab3 protein to compete with the endogenous Gab2 for the G‐CSF‐dependent signaling. In Gab3‐overexpressed cells, the level of tyrosine phosphorylation of endogenous Gab2 by G‐CSF stimulation was markedly downregulated, while the phosphorylation of Gab3 was significantly enhanced. The Gab3‐overexpressed cells continuously proliferated in the medium containing G‐CSF and lost the ability to differentiate to the mature neutrophil, characterized by the lobulated nucleus. The G‐CSF stimulation‐dependent tyrosine phosphorylation of Gab3, the association of SHP2 to Gab3 and the following mitogen‐activated protein kinase (MAPK) activation were prolonged in the Gab3‐overexpressed cells, compared to the parental cells, where the binding of SHP2 to Gab2 protein and thereby the activation of MAPK were not sustained after G‐CSF stimulation. Inhibition of MAPK by pharmaceutical inhibitor restored the Gab3‐overexpressed cells to the ability to differentiate to mature neutrophil. Therefore, G‐CSF‐dependent Gab2 phosphorylation and following its downregulation led the short‐term MAPK activation. The downregulation of MAPK after transient Gab2 phosphorylation was necessary for the consequent neutrophil differentiation induced by G‐CSF stimulation
