From physical mobility to psychological mobilization: The benefits of changing location and caregiver in a mobile team for adolescent psychiatry

We have developed a mobile team for adolescents with psychological difficulties that can intervene within 48 hours, if necessary. Practically, caregivers working in pairs go wherever the adolescents are (home, General Practioner’s office, etc.), travelling in a motorhome designed as a mobile office. This method allows us to approach more closely the adolescents and their families in the here and now that corresponds to our societal evolution. Most of the adolescents seen by the mobile team do not express any explicit demand but the demand is expressed by the professionals in direct contact with these adolescents in difficulty (school professionals, General Practitioners, etc.), who alert the mobile team and solicit the adolescents’ parents to call the mobile team. One characteristic of this mobile team is the mobility of setting (by changing locations, including the use of a mobile office, and caregivers, so that multiple representations are mobilized). Statistical analyses conducted on 520 adolescents followed by the mobile team showed that the first meetings tend to take place in the family’s home, subsequently transferring to the mobile office and finally in the community mental health centres. There is therefore a transition from the living space (a place that is part of the here and now) to the caregiving space (a space of thought and for thinking), with the mobile office serving as an intermediate step in this movement towards accessing care. Furthermore, there was a significant association between changes of locations and continuity of care. Thus, there were significantly more breakdowns in continuity when the consultations all take place in a single location (family home, mobile office, community centre). The results and their therapeutic implications will be discussed in this article, especially with regard to the key role played by physical movement in psychological mobilization, and by plurality of representations associated with different locations and caregivers.

Development and Evaluation of Intersection-Based Turning Movement Counts Framework Using Two Channel LiDAR Sensors

This paper presents vehicle localization and tracking methodology to utilize two-channel LiDAR data for turning movement counts. The proposed methodology uniquely integrates a K-means clustering technique, an inverse sensor model, and a Kalman filter to obtain the final trajectories of an individual vehicle. The objective of applying K-means clustering is to robustly differentiate LiDAR data generated by pedestrians and multiple vehicles to identify their presence in the LiDAR’s field of view (FOV). To localize the detected vehicle, an inverse sensor model was used to calculate the accurate location of the vehicles in the LiDAR’s FOV with a known LiDAR position. A constant velocity model based Kalman filter is defined to utilize the localized vehicle information to construct its trajectory by combining LiDAR data from the consecutive scanning cycles. To test the accuracy of the proposed methodology, the turning movement data was collected from busy intersections located in Newark, NJ. The results show that the proposed method can effectively develop the trajectories of the turning vehicles at the intersections and has an average accuracy of 83.8%. Obtained R-squared value for localizing the vehicles ranges from 0.87 to 0.89. To measure the accuracy of the proposed method, it is compared with previously developed methods that focused on the application of multiple-channel LiDARs. The comparison shows that the proposed methodology utilizes two-channel LiDAR data effectively which has a low resolution of data cluster and can achieve acceptable accuracy compared to multiple-channel LiDARs and therefore can be used as a cost-effective measure for large-scale data collection of smart cities.

ON THE SUBURBANIZATION OF BEIJING

Suburbanization is a stage of urbanization provess. The author discesses the situation of Beijing from the data of three population censuses(1964, 1982, 1990) and considers that the suburbanization in Beijing has been in process since 1982. During 1982-1990, population of all districts of the inner city lost 82 000 persons and in fact the permanent residents holding the household registration lost 144 000, which is about 6. 12% of permanent residents in the inner city.Like the West, suburbanization in China the happened against the macro backgrounds of improvements of transportation and loving conditions, growth of urban population moving from rural areas. But in the case of the forces that make decentralization possible, China is different from the western countries. In China, the levels of economy and urbanization are rather low, the red middle class is not rich; only very few Chinese families families provate cars, and the inner cities still have great attraction to Chinese people. The author considers three causes of decentralization: (1) reform of urban land use system brings about migration from the core area; (2) construction of a large number of city roads reinforces this process; (3) reforms of housing system and renovation of dilapidated houses encourage outward movement. However, the process wasn’t of spontaneity of any individual but of the leadership of government and “Dan Wei” (Work Unit).

Environments Aware for Prolonging the Lifetime of Sensor Nodes Deployed in WSNs

Providing a pretty adequate environment condition between the transmission and the receiver for a WSN (wireless sensor network), in which deployed sensor nodes and fusion center, is investigated in the paper. Moreover, an algorithm promotes the energy efficient, increases the accuracy of sensing data and prolongs the lifetime of sensor nodes deployed over an WSNs is proposed. On the basis of adopting sensor management, which involves sensor movement sequences, sensor location arrangement, lifetime requirement for sensor nodes deploy surveillance environment, and the data fusion center, are addressed too. Simulation results from the lifetime performance for sensor nodes defeated by parameters about the environment around the WSNs are illustrated. Parameters aforementioned are including sensing distance, path loss factor, number bits of a transmitted packet, and interference suffering from the path of data transmission etc. Furthermore, the algorithm of sensor location arrangement is modified for the purpose of improving the lifetime performance in WSNs environments. In addition, simulation results show that the proposed algorithm in this paper is not only definitely to improve the energy efficient sufficiently, but the sensing accuracy and the lifetime performance of the sensor nodes are also prolonged significantly.

Images of the Future from the Past： The Metabolists and the Utopian Planning of the 1960s

During the 1960s, many changes reshaped the economy, the society and the arts. The Cold War, the Space Race, the construction of a new middle class in most western societies led by the postwar economic prosperity with unprecedented urban growth followed by severe environmental problems fostered the design of spectacular urban utopian cities and mega-architectures. In those years, Japan was the source of highly influential bold and visionary urban and architectural ideas which relied on advanced technology. These ideas were conceived on the thought that cities could be seen as gigantic but impermanent entities able to transform itself according to an organic process of adaptation of its elementary components. This paper briefly revisits and critically discusses the legacy of the iconic mega-strnctural projects of Japanese Metabolist Movement and other visionary architects and planners of the 1960s, such as Paolo Soleri, Buckminster Fuller, Archigram. It attempts to enlighten the continuity with contemporary innovative and experimental urban models and ideas for the society and the city of the future, such as the Smart Cities, Eco-Cities, Green Urbanism, whose design is led by concerns related to climate change, the necessity of energy efficiency, the improvement of urban landscape and the valorization of depleted natural resources.

Research Progress and Trends of Urban Public Facilities' Location

Urban development in China has recently encountered various problems,and many of these problems have been caused by uneven distribution of public facilities in different districts,so it is signifi cant to choose reasonable locations for urban public facilities. Current researches on location of urban public facilities in China cover various aspects,involve different units,show diverse features,and make outstanding contributions. However,these researches have also obvious limitations. The future study on public facilities' location will focus on specifi c application of the model in different cities,or better consider characteristics of the city.

Strategic Study on Integration of Port and City Development in Rizhao

agglomeration of the Yangtze Delta （UAYD）, one of the most developed regions of China, has witnessed an increasing prevalence in building ecological cities when the ecological cities are pursued by many modern cities, and great achievements have been made in this regard. It is inevitable, however, that certain problems exist during the construction of ecological city, which include but not limited to non-harmonious development of urban complex ecosystem, and the difficulty in quantifying eco-city construction or incomplete quantification in assessing the con- structiori of present and future eco-city. Based on the analysis on social-economic conditions and regional conditions of the UAYD, this paper attempts to set up an index system of eco-cities combining with local characteristics, and to adopt the indices of eco-city, urban harmony, and eco-city colligate to evaluate the ecological level, urban harmonious development and eco-city construction of cities within the UAYD. Results indicate that among 15 cities in UAYD, Suzhou City ranks the highest in terms of eco-city construction, whereas Nantong ranks relatively lower; sustainable eco-city construction is possible only when cities are developed in every respect of harmony.

Optimization designs of artificial facilities in deserts based on computational simulation

Sediment transport of sand particles by wind is one of the main processes leading todesertification in arid regions, which severely impairs the ability of mankind to produce and live by driftingsand into settlements. Optimization designs of artificial facilities have lately attracted extensive interest forhuman settlement systems in deserts because of their acceptable protection effect, convenience ofimplementation, and low material cost. However, the complexity of a settlement system poses challengesconcerning finding suitable materials, artificial facilities, and optimization designs for sand depositionprotection. In an effort to overcome these challenges, we propose a settlement system built with brick, solarpanel, and building arrays to meet the basic needs of human settlements in arid regions while preventingwind-sand disasters. The wind flow and movement characteristics of sand particles in the brick, panel, andbuilding arrays were calculated using computational fluid dynamics and discrete phase model. Theperformance of three types of arrays in wind-sand flow in terms of decreasing the wind velocity and sandparticleinvasion distance was evaluated. The results show that the wind velocity near the surface and thesand invasion distance were significantly decreased in the space between the brick arrays through properlyselected vertical size and interspaces, indicating that the brick arrays have an impressive sand fixing andblocking performance;their effective protection distance was 3–4 m. The building arrays increased the nearsurfacewind velocity among buildings, resulting in less deposition of sand particles. The solar panel arrayswere similar to the building arrays in most cases, but the deposition of sand particles on solar panels exerteda negative effect on energy utilization efficiency. Therefore, taking the optimal configuration of thesettlement system into consideration, this study concludes that (1) brick arrays, which were proven effectivein preventing sand particles, must be arranged in an upwind area;(2) solar panel arrays could accelerate thewind flow, so they are best to be arranged at the place where sand particles deposited easily;and (3) buildingarrays present a better arrangement in downwind areas.

Dynamic movement-based location update in LEO networks

Mobility management is an important aspect of the LEO systems. In terrestrial wireless network, the movement of the user triggers the location updating and determines the paging scheme, while in LEO satellite systems, the location updating and paging is mainly based on the movement of satellite. Terrestrial location management techniques must be altered to fit LEO systems. This paper introduces a modified movement based location update and paging scheme in LEO networks. In this scheme we propose the meta cell concept, which includes two spot beams of one satellite. First we present the location management scheme based on the architecture with meta cell location area. Then an analytical model is applied to formulate the cost of location updating and location paging for the and movement meta cell based dynamic location update scheme. The comparison of performance between meta cell architecture method and conventional signal spot cell architecture method is provided to demonstrate the cost effectiveness and robust of the proposed scheme under various parameters. To reduce the impact of meta cell architecture on location paging cost, we present forced location update strategy which used in the cases that the meta cell includes the two spot beams from different satellites.

URBAN FORM FOR A SUSTAINABLE FUTURE: How Sustainable Is Distributed Working in the Networked City?

Our understanding of urban form depends on how we perceive the city.Much of the literature on urban form(1)has focused on the pre-industrial and industrial city,celebrating its compact form,contiguous functions and single dominant centre.More recently writings by Castels(2)and Soja(3)have described the dispersed,city of the post industrial era.This networked city triggered by the freedom afforded by the new technology(4)has exposed a new dimension to urban form.The model of the compact city advocated by those such as Lord Rogers Task Force for delivering the Urban Renaissance(5)is being questioned(6)and a new model of“high density nodes,in a high density landscape resulting in a low density city,”as in the Deltametropolis,described by Dirk Frieling(7).Compactness,cramming more development into the city and making public spaces of a higher density and quality,Rogers and Burdett argue(8)will make“urban living attractive,ecologically sustainable,economically strong and socially inclusive.”The alternative argument is that the economic success of cities is reliant on the networking of resources across a metropolitan region.Echenique argues(9)that cities disperse in their search for mobility and space.“Mobility increases the effi ciency of households and fi rms which in turn generates more income and profi ts.As income increases,so does the demand for space,residential and commercial alike.”Sustainability has become the current banner of political correctness.Sustainability however is a slippery word.It is easy to focus on one aspect and lose the value of its holistic meaning.For many architects“green buildings”equals a sustainable future.However,clever design solutions single-mindedly pursued with little regard to the wider exploration of the potential environmental savings that may be achieved through organisational innovation are only half the answer.A holistic approach concerned with both building and organisational design and focused on“lean thinking”(10)could make considerable inroads into reducing the ecological footprint.The paper draws on DEGW’s experience of advising major corporations and cities on strategies for managing the process of intensifi cation and change(11).It explores how major improvements might be gained in meeting our goals for the sustainable city through reconsidering the way we work and allocate space.The underlying proposition is that technology has offered us new opportunities which have changed our paradigm of living and working.This in turn has provided us with a new perception of the city,as a distributed series of high density centres connected by good public and private transport,within a low density landscape.The paper argues that considerable improvements in workplace sustainability can be achieved by applying a holistic approach.These may include a combination of strategies,from rethinking the organisation of work processes and the locations and time work is undertaken,to reducing the need for resources by a more intensive use of land and fl oor space.Disjointed,dispersed“urban sprawl”can be wasteful.The alternative emerging urban form is a planned,dispersed,“networked”city with well integrated public and private transport that yields greater choice of location and lifestyles so supporting social,economic and environmental sustainability.

The effect of qibla direction on the hierarchy of movement in mosque:A case study of mosques in Yazd,Iran

In the architecture of Iranian-lslamic mosques,besides the geographic directions affecting the climate,the direction of qibla also affects their architecture.In the present study,based on the descriptive-analytical method and using the material flow pattern and the activity relationship chart,the pattern of the path of human movement from the entrance to the altar,as well as the degree of proximity of each space relative to other spaces in this movement path were investigated.After describing and analyzing the qibla axis through the structural study on 12 samples of the traditional mosques of Yazd owing to the attention given by the people of this region to religious discussion and their efforts to focus on the axis qibla direction-the hierarchy of human movement was investigated with reference to the mosque being placed in the axis of the qibla direction considering the geometry,arrangement of forms,and interior functions.Studies in this area indicate that the architects and builders of mosques have considered the preservation of the divine orientation or the qibla,the path of human movement from his early arrival to his placement in the direction of the qibla axis,and the preservation of geometry as the valuable principles.
