Livelihood System

Here is presented an approach to the simulation of complex in its multicomponent structure for implementing the functions of city activity. The approach is based on the paradigm of the city compatibility with the Biosphere and phrased on the principles of its self-organization. A conceptual model of the urban livelihood system in the form of a multicomponent natural and technogenic structure is also described. A mathematical model of an open dynamic compatible with the Biosphere urban livelihood system with the choice of the governing parameters for management is developed.

Abstract This article investigates the collective responsibility organizations among boatmen in nineteenth-century Chongqing, when the city became one of the most important metropolises on the southwest Qing frontier. It also introduces two successive turning points in self-organization that were associated with two different classes of boatmen – skippers and sailors. First, in 1803, skippers gained the authority to institutionalize their organizations through their negotiations with the local state regarding official services and service fees. Second, when similar service and fiscal tensions emerged between skippers and sailors in the mid-nineteenth century, the skippers facilitated and supervised the institutionalization of collective responsibility organizations that were run by the sailors themselves. By contextualizing this expansion of collective responsibility organizations within the multilayered interactions between skippers and sailors, this article proposes that the perspective of interclass networks is crucial for deepening the study of state−society interactions, the capital−labor relationship, as well as the tension between imperial integration and regional diversity in early modern China.

Urban Stress

PurposeThis paper presents a critical review of studies which map the urban environment using continuous physiological data collection. A conceptual model is consequently presented for mitigating urban stress at the city and the user level.Design/methodology/approachThe study reviews relevant publications, examining the tools used for data collection and the methods used for data analysis and data fusion. The relationship between urban features and physiological responses is also examined.FindingsThe review showed that the continuous monitoring of physiological data in the urban environment can be used for location-aware stress detection and urban emotion mapping. The combination of physiological and contextual data helps researchers understand how the urban environment affects the human body. The review indicated a relationship between some urban features (green, land use, traffic, isovist parameters) and physiological responses, though more research is needed to solidify the existence of the identified links. The review also identified many theoretical, methodological and practical issues which hinder further research in this area.Originality/valueWhile there is large potential in this field, there has been no review of studies which map continuously physiological data in the urban environment. This study covers this gap and introduces a novel conceptual model for mitigating urban stress.

In the crowded cities of the present age, public spaces can provide a quiet area away from the hustle and bustle of the city that citizens can interact with by incorporating utility features and meeting human needs and Relax there. Small urban spaces are among the most important and effective urban spaces to achieve this goal. Because these spaces due to their small size and lower costs (compared to larger spaces) for construction can be created in large numbers and distributed throughout the city. In this way, citizens will be able to reach a public urban space on foot in a short time. If these spaces are well designed, they can encourage people to stay in and interact with each other. It is not difficult to identify and experience high-quality successful places, but identifying the reasons for their success is difficult and even more difficult, understanding if similar spaces in other places can be considered successful. This question is important because public space with deep social content is considered a cultural product. Public space is the product of the historical and socio-cultural forces of society. Therefore, one of the most important issues that should be considered in the study of public spaces and the reasons for their success is the cultural context. In Iranian cities that have been influenced by the values and principles of Islam,recognizing Islamic principles and their role in shaping public spaces can lead us to desirable results. The purpose of this article is to develop a conceptual model of successful small urban spaces with an emphasis on cultural issues, especially in Iranian-Islamic cities. In this regard, the effective criteria for the success of urban spaces in general and small urban spaces in particular in the two categories of Western countries and Iranian Islamic cities were examined and then, taking into account the criteria derived from cultural theorists, the conceptual model of research with 38 subcriteria is provided.

The Middle East Respiratory Syndrome (MERS) has been identified in 2012 and since then outbreaks have been reported in various localities in the Middle East and in other parts of the world. To help predict the possible dynamics of MERS, as well as ways to contain it, this paper develops a mathematical model for the disease. It has a compartmental structure similar to SARS models and is in the form of a coupled system of nonlinear ordinary differential equations (ODEs). The model predictions are fitted to data from the outbreaks in Riyadh (Saudi Arabia) during 2013-2016. The results reveal that MERS will eventually be contained in the city. However, the containment time and the severity of the outbreaks depend crucially on the contact coefficients and the isolation rate constant. When randomness is added to the model coefficients, the simulations show that the model is sensitive to the scaled contact rate among people and to the isolation rate. The model is analyzed using stability theory for ODEs and indicates that when using only isolation, the endemic steady state is locally stable and attracting. Numerical simulations with parameters estimated from the city of Riyadh illustrate the analytical results and the model behavior, which may have important implications for the disease containment in the city. Indeed, the model highlights the importance of isolation of infected individuals and may be used to assess other control measures. The model is general and may be used to analyze outbreaks in other parts of the Middle East and other areas.

A methodology has been developed for assessing public transport passenger traffic in the city. A mathematical model based on fuzzy logic is presented. The main criteria for assessing the attractiveness of passenger traffic are: the interval between vehicles, technical condition of the vehicle, route length, time of day. In the mathematical model, all input linguistic variables and output variable, their terms and membership functions are described. A fragment of a fuzzy knowledge base presented in the form of production rules is presented. At the exit, the dispatcher receives an output variable – the degree of confidence in the attractiveness of the route. Based on this assessment, the dispatcher can make a number of necessary changes to improve the functioning of the route. The software is implemented as a web service. This software will be convenient for dispatchers to use for planning public transport routes. Fifteen selected routes were taken for research, which are the most popular in the city. These routes were proposed for evaluation by three controllers. The results obtained from dispatchers were compared with the results of the fuzzy inference implemented in the software. The main advantage of using this software product is the ability to build a dynamic schedule based on the analysis of the dispatcher. This, in turn, will allow passengers to receive a better transportation service within the city

The Cost

The demand for more sustainable business models is increasing the need for current businesses to develop their business processes and value creation mechanisms. One way to improve sustainability is sharing resources and services in a new sharing economy paradigm. This chapter builds a conceptual model for taxi ridesharing to describe the value potential that is born by increasing the efficiency of taxi businesses. First, a framework for multisided markets is built to understand the different value elements of taxi ridesharing. Then, a conceptual mathematical model is introduced to understand the value symmetries including the cost saving potential and allocation from the perspectives of the customer and the supplier. The model shows that it is possible to have a system that creates value for both the taxi driver and the passenger, while simultaneously leading to significant reduction in CO2 emissions.

This chapter studies the dynamics of Bogotá Region based on the New Economic Geography and the recent works on economic development in two big dimensions: the economic and the spatial structure; that is, productivity and polycentrism. The central thesis, supported on an econometric exercise for SMEs in 20 cities in Bogotá-Sabana region, is that with greater strength in the interior of Bogotá and less in the city region, a transition from monocentrism to functional polycentrism is consolidating. Krugman's Edge Cities model concludes that polycentrism comes from a process of spontaneous self-organization and produces a territorial order according to the mysterious ZIP law and consistent with efficiency, equity, and sustainability.
