Use and Perceptions of Pedestrian Navigation Apps
Pedestrian Navigation Applications (PNAs) provide assistance in terms of self-localization, space recognition, and turn-by-turn navigation. The use, motivations and perceptions associated with these applications have been under investigated due to users being insufficiently involved in their design and development. This paper analyses the extent to which PNAs are used for assisting people to walk, the frequencies and reasons of using these applic…
Understanding quantum numbers
The study aims to investigate students' conceptualisation of the quantum numbers concept through their verbal descriptions and pictorial representations of the corresponding atomic structures. The study was conducted with the participation of 192 12th-grade students from six secondary schools in Northern Greece, via a paper-and-pencil test, developed by two of the authors, including four open-ended tasks. Each task comprised of two parts aiming t…
HIV patient access to healthcare services in post-austerity era in Greece
Purpose The ten-year economic crisis and the ensuing fiscal adjustment that Greece experienced between 2009 and 2018 has had a major impact on patient access to health-care services and resulted in an increase in unmet population health needs. The present study aims to assess the impact of economic crisis and ensuing austerity on HIV patient access to health-care services. Design/methodology/approach A cross-sectional study was carried out betwee…
A fine-grained analysis of students’ explanations based on their knowledge of the atomic structure
The present work explores students’ repertoire of explicit knowledge fragments relevant to the atomic structure, seeking to answer which of those and through which routes are activated by students when constructing their explanations for some everyday situations. For this purpose, six tasks describing different situations were given to 225 students of the 10th and 11th grades of secondary schools from Northern Greece. Students’ responses were qua…
Toward a System Dynamics Modeling Framework for Effective Political Organization Management Strategies
In the face of the high complexity and uncertainty in the political market landscape, developing effective strategies becomes the greatest challenge for political organization managers. Traditional tools for strategy analysis become obsolete in front of the dynamic complexity that governs political organizations and their environments. Drawing knowledge from a literature review on political marketing strategies and models, this paper employs syst…
On Sudden Urban Growth
The purpose of this paper is to explain sudden urban growth, a global phenomenon of astonishing force that presents one of the greatest challenges facing humanity today. The forces that shape urban growth are many and varied. Such forces produce an array of histories of urbanization ranging from continuity to various catastrophic shifts along the population trajectory. It is seen that the realized history of urbanization explicitly depends on the…
Social Values and Social Justice
What are the deep causes of inequality? I restrict the meaning of “inequality” to cases where there is a clear moral content, that is, to cases where individuals under consideration are otherwise s
Spatial Externalities I
How does one endow an externality with a spatial distribution? If this problem can be solved then it should be possible to understand (in a general, qualitative manner) how cities spatially adapt to different spatial externalities
Spatial Externalities Ii
Cities adjust spatially to interaction, pollution, congestion, prejudice, and to the class of incompatible land uses in general. For the one-species city, facing particular issues of the urban environment in isolation is inefficient. The study of interacting species under conditions of integrated spatial equilibrium may provide a key to a theory of land-use planning
Spatial Nonconvexities
Modern economic theory has experienced a persistent shift away from partial equilibrium modelling and towards the theory of general competitive equilibrium. Spatial economic analysis, however, has by and large remained rooted in the older approach. This conservatism may be explained in part by the stringently aspatial manner in which general equilibrium theory is conventionally expressed. This paper attempts to redress this imbalance by consideri…

On Issues of Urban Policy
Fundamental Problems of Theoretical Planning
This essay deals with problems of planning fundamental in the sense that they transcend socioeconomic systems. It is partitioned into four. The first part refers to some problems of transition from the realm of individuals to the social realm. The second part establishes the generality of the concept of an optimum city and its anti-utopian character. The third part discusses urban policy, politics and their impact on the attainment of an optimum …
Urban Residential Analysis
Part 1 of this two-part series was concerned with the description and analysis of elements that transcend diverse urban structures of the 'service' type. The conclusions were general and abstract. Beyond this unified realm a more detailed description of urban form requires additional assumptions. The nature of such assumptions defines urban form within the confines of positive or normative analysis. Here the additional assumptions define spatial …
Urban Residential Analysis
Equilibrium efficiency and optimum are fundamental concepts that characterize the form of ideal cities. Such forms, coupled with the 'closed'-'open' distinction, provide a rich gamut of urban structures. Yet transcending this diversity of types and individualistic attributes there is a more general, unified level of analysis. Long (1971) has worked at this level, and the trend is continued in this paper. Externalities, policies, and public goods …
Crude Inferences on Spatial Consumer Behavior∗
Multiple center population density gradients derived within a theoretical framework permit substantive interpretation of the parameters. Estimated parameters for metropolitan Toronto and southern Ontario are interpreted as travel frequencies to centers of different orders. At the intraurban level different assumptions about prevailing trip patterns and purchase frequencies imply different relative travel frequencies. This permits inferences about…
The Impact of the Environment upon the Spatial Distribution of Population and Land Values
The associated utility functions may be thought of as being defined in terms of nonspatial and spatial characteristics. The spatial characteristics refer in most cases to space abundance and accessibility. This is implicit in Hochman and Pines [5] and Muth [8], and explicit in Alonso [1], Beckmann [2], Casetti [3], and Walter [11]. A variant is found in Casetti and Papageorgiou [4] and Niedercorn [9] where leisure replaces accessibility: other th…
A Spatial Equilibrium Model of Urban Structure
The Population Density and Rent Distribution Models within a Multicentre Framework
This paper describes a method used for developing population density and rent distribution models for a hierarchy of centres. Such models may be thought of as describing intraurban or interurban situations. The discussion is confined to the generalization of existing single centre models. It is seen that strong formal links may exist between a single centre model and its multicentre counterpart
A Theoretical Evaluation of the Existing Population Density Gradient Functions
where D(s) is the population density at distance s from the center, ao and a are parameters (a is a positive number). Equation (1) was repeatedly tested in several cases for different parts of the world and for the past 150 years.1 Whenever examined, the relationship proved to be statistically significant and most often the regression analysis indicated that the model had an unusually high explanatory power. In consequence, the concept has gradua…
