Spatial Distribution of Shopping Malls and Analysis of their Trade Areas in Istanbul

This paper investigates the spatial distribution of shopping malls with respect to population and analyses the factors which effect the shopping mall location. According to the results, while the shopping mall space ratio is higher than population ratio in the intermediate zone, the reverse is true in the periphery. The relationships between the shopping mall space and income, population and distance to the central business district (CBD) of the locations are investigated by the use of regression analysis. The results reveal that income is the only factor affecting the location of shopping malls among those considered. In addition, three shopping malls from the inner and peripheral zones of Istanbul were analysed with respect to frequency to shopping centres and characteristics of trade areas. According to the results, the size of the catchment area of the shopping mall from the inner zone is larger then the peripheral ones due to higher accessibility with alternative transportation systems and supporting functions in its surrounding areas. The results fall within the concept of central place theory. Further research is suggested by expending the study to the other areas of the city with different characteristics to calculate their retail potential and their spatial implications.     

What's a School Worth to a Neighborhood? A Spatial Hedonic Analysis of Property Prices in the Context of Accommodation Reviews in Ontario

Due to a change in capital funding formula, many school boards across the Province of Ontario engaged in Accommodation Reviews to rationalize the supply of school capacity. This process led to numerous school closures and raised important policy questions regarding the economic value of a school in terms of its capitalization into property values and, by extension, how the closure of a school might affect local neighborhoods. To explore these questions, this research uses spatial hedonic methods to estimate the implicit value of accessibility to schools in the City of Hamilton, Ontario. Spatial Durbin model results provide evidence of a significant negative correlation between distance to schools and housing prices in the Canadian context. This suggests that accessibility to schools is capitalized into property values and that the closure of a neighborhood school may result in potentially significant losses of economic value in communities.     

Population Distribution and Spatial Structure in Transitional Chinese Cities: A Study of Nanjing

Two geographers use population surface model techniques to analyze the distribution of population in Chinese cities. Focusing on Nanjing, they utilize detailed urban land use and building distribution data to develop a productive alternative method to reveal spatial variations in the distribution of inhabitants. The findings indicate that despite suburbanization, Nanjing remains a compact city with a population density that declines rapidly as distance from its central business district increases. Also, suburbanization has been limited to an inner area where population is densely distributed while commercial and office development is less prominent. Lastly, commercial activities influence the distribution of urban inhabitants and suburbanization more significantly than industrial development in suburbia.

Application of Quantitative Methods of Settlement Analysis to a Lower-Level (Intra—Oblast) Economic Regionalization

Two quantitative techniques—the mean center of population of the old centrography school, and the potential of population—are applied to settlement analysis in Eastern Siberia for purposes of lower economic regionalization. The migrations of the mean center of population of Yakut ASSR and Irkutsk Oblast are interpreted in terms of regional development trends from the 1920s to the 1960s. Analyses of the potential of population for different dates suggest the formation of areal production nodes that can be used in delimiting lower economic regions. The boundaries between such lower-order regions tend to pass through undeveloped and sparsely settled areas that show up as low values on maps of the potential of population.     

From equalisation to rationalisation: public health care provision in New South Wales

This article examines the changing nature of the resource allocation formula for health care provision in New South Wales. It looks at the technical changes to the formula reviewing its problems and limitations and subsequent modifications. The impact of the formula on actual resource provision is established and this provision is placed in the context of health policy and public expenditure debates in Australia. Finally, the formula and its use as a rationalisation device are examined in relation to economic crisis and state practice with the suggestion being made that certain features of the Australian state may lead to a review of aspects of the theory of the state.     

Testing the ‘Laacher See hypothesis’: a health hazard perspective

It has recently been suggested that the Laacher See volcanic eruption, which occurred around 13,000 years ago, initiated significant demographic fluctuations along the northern periphery of Late Glacial human settlement and that these led to a number of material culture transformations. The origins of the Southern Scandinavian Bromme culture and the northeastern European Perstunian culture as well as the temporary abandonment of Central European regions have been linked to this eruption. However, it remains unclear precisely which aspects of the eruption stimulated Late Glacial foragers to abandon their traditional ways of life. Paradoxically, the culture–historical impact of the eruption appears greater further away from the eruptive centre. Here, we investigate one potential middle-range link between the Laacher See eruption and Late Glacial fauna and foragers: tephra as a health hazard. We use laser-diffraction particle-size analysis to quantitatively investigate tephra from one site with a secure Late Glacial archaeological deposit. In addition, we use values previously reported in the literature and a predictive model to calculate the hazard potential along a transect of two of the three major Laacher See tephra fans. Our results show that the Laacher See tephra may have posed a potential health hazard and that its hazard potential may have increased with distance from the vent. To our knowledge this is the only study that attempts to quantify the changing grain-size composition of tephra fall-out longitudinally in this way, at least with regard to a prehistoric eruption. We close by discussing, more speculatively, other possible health-pertinent effects of the Laacher See eruption and suggest ways in which future work can further evaluate the impact of this eruption on Late Glacial populations.     

A Covering Tour Model for Planning Mobile Health Care Facilities in SuhumDistrict, Ghama

The provision of adequate primary health care in developing countries is often troublesome. The problem is to provide a sufficient number of facilities to be geographically accessible, yet few enough to be properly stocked and staffed. In many less developed countries accessibility problems are exacerbated by extensive rainy seasons in which travel is only possible on paved roads. Using the covering tour model we investigate the use of mobile facilities to resolve this dilemma in Suhum District, Ghana. The model minimizes a mobile facility's travel while serving all population centers within range of a feasible stop. Computational results show that in the rainy season the model cannot provide full coverage; over six percent of the population is beyond a covering distance of eight kilometers. In the dry season, 99 percent of the population can be served by a tour at a covering distance of seven kilometers.Beyond a distance of four kilometers, the dry season problem becomes a trade-off between the distance traveled by healthcare patrons and mobile facilities. These results illustrate the importance of flexibility of mobile systems: if accessibility cannot be provided in all seasons it may still be provided at favorable times of the year.     

POPULATION ANALYSIS ON THE MICROCOMPUTER: A SYSTEM OF SOFTWARE PACKAGES

This paper describes a system of versatile software packages that has been developed by the author for population analysis on IBM-compatible microcomputers using PC or MS DOS. The series includes programs for the production of life tables, the analysis of spatial patterns and temporal trends in mortality, population projections, stationary-state population simulations and demographic planning, cohort survival estimates of net migration, and the analysis of migration matrices. Each of the programs in the series is discussed in terms of its principal analytical features, associated conceptual and methodological issues, and potential applications. The programs are intended for use both as basic research and planning tools and as instructional aids in university-level courses. The programs and related documentation are available on a set of four 360K diskettes.     

An Attempt at a Quantitative Evaluation of the Natural Resource Potential of Regions in the USSR

A technique for measuring total resource potential is proposed. For a selected set of resources (coal, oil and gas, iron ore, hydro power, timber, arable land, forage land), reserves are divided by the estimated period of use to obtain annual productivity. The resources are then valued in terms of a set of unit prices. The inclusion of agricultural land resources tends to assign a greater role to the Western portions of the USSR than is normally the case in resource estimates. The significance of the mineral-rich Eastern regions is also understated by limiting reserve estimates to those that are likely to be accessible in the foreseeable future (10 to 15 years). Resource density per unit area shows particularly high values for the southern agricultural regions, especially where they are combined with significant mineral and hydro resources. Resource availability per 1000 population shows expectedly high values for the sparsely populated Eastern regions of the USSR.

URBAN‐TO‐RURAL POPULATION GROWTH LINKAGES: EVIDENCE FROM OECD TL3 REGIONS*

The objective of this paper is to understand, from an international comparative perspective, how population growth in rural regions is affected by the relationship with their nearby urban centers. By means of a cross‐sectional analysis on OECD small regions (Territorial Level 3), the paper distinguishes spread effects—positive spillovers arising from urban growth—from the net effect of distance to nonrural places. The results show that spread effects outweigh backwash effects, so that rural regions benefit from growth in urban places. A rural region's distance from urban and intermediate regions has a negative effect on its population growth rate. Nevertheless, both the strength of this effect and the growth spillovers decline with distance, and this occurs relatively faster in Europe. The results further suggest that proximity to large urban areas has a higher positive influence than proximity to intermediate areas, but only outside Europe.     

Relationships between Modified Mercalli Intensity and Engineering Ground-Motion of the Earthquakes in Persia

New empirical relationships between modified Mercalli intensity (MMI) and engineering ground acceleration (PGA) of the earthquakes were generated for the Iranian territory. MMI and PGA values were gathered from 16 large earthquakes. We derived two sets of relationships which predict MMI in terms of PGA; each developed using both horizontal and three components of accelerograms. The first set is independent of earthquake magnitude and epicentral distance. Better results were observed when magnitude and epicentral distance conditions were included into equations. They might be used for both rapid assessments of ground shaking and also mapping damage potential in Iran and neighboring area.     

Distance and social interaction in a Victorian city

The paper examines patterns of marriage in a small industrial city—Huddersfield—between 1850 and 1880, when the residential structure of the city was becoming more modern in its spatial organization. The need to interpret distance-decay patterns of interaction in their social context is stressed. The apparently unchanging relationship between physical distance and frequency of interaction is related to the balance between changing patterns of individual mobility, class consciousness and scales of residential segregation. The more extensive interaction fields of the rich are attributed to their greater mobility, but also their lower population density. The close-knit patterns of the poor reflect their higher population density and more particularly the segregation of the Irish community. Finally, the differences between normative (within-class) and non-normative (between-class) marriage distances are considered. It is suggested that physical distance operated independently of social distance, although this conclusion requires further testing at different scales of analysis, and using information on forms of interaction other than marriage.

The use of stable isotope ratio analysis to distinguish multiple prey kill events from mass kill events

Archaeologists working with prey animal bonebeds are interested in determining whether the animals were obtained through a single, mass kill event or instead accumulated over time from multiple hunting events. This is often difficult to determine. The author investigated the use of stable isotope ratio analysis to distinguish accumulations of individuals derived from multiple populations from mass kills of individuals from a single population. Carbon, oxygen and strontium stable isotope ratios were measured in tooth enamel from modern pronghorn (Antilocapra americana) with known mortality circumstances. These ratios were then analyzed using basic statistical methods as well as a scaled distance technique that permits integrated analysis of multiple isotopes and multiple samples, and a bootstrap subsampling approach was used to quantify differences among populations. It appears that, in some circumstances, stable isotope analysis can contribute to distinguishing bonebeds originating as accumulations of individuals derived from multiple populations from mass kills of individuals from a single population. Three-element isotope ratio distance measures provide the best isotopic indicator of pronghorn bonebed population origins, especially when bootstrap subsampling is used to compare to sites of known pronghorn population composition.     

Applications of Mathematics to Population Geography

Three levels of application of mathematics are considered in order of increasing complexity. The first level involves measurements of processes and phenomena, the second the derivation of empirical relationships, and the third the construction of deductive models reflecting the basic mechanism of processes and phenomena. Examples of the three levels are given: Boyce's city-shape index illustrates the first; and Clark's formula for population density within cities is given as an example of the second. The second level is also illustrated by Medvedkov's procedure for forecasting the interplay of natural and mechanical movement of population, involving the use of matrix algebra. On the third level, Medvedkov constructs models of flows of pedestrians doing their shopping on their way home from work to determine an optimal distribution of retail outlets.     

Seasonal dating and the valve-pairing technique in shell-midden analysis

Three-dimensional excavation of 23 artifact fragments and 4382 shells was carried out in the shell layer of an abandoned dwelling pit. Principal component analysis using three locational variables was used for drawing the central axes and the regression plane of the shell layer. Valve-pairing carried out on the clam Meretrix lusoria indicated that 380 pairs could be established among a total of 2089 unbroken valves. Preservation of shells was estimated at 70% by comparing the number of shells found in the shell layer with the clam population size which was in turn calculated by a probability formula using paired valves among samples. In addition to these data, the distance separating pairs gave some idea of the movement of shells. Seasonal dating by daily growth line counting showed that the shell layer could be subdivided into at least three main seasonal layers and that the period of accumulation was approximately 500 days.     

INTERREGIONAL MIGRATION ANALYSIS

A formula for migration rate, proposed by Bogue, Shryock and Hoermann (1957), is modified to yield a simple coefficient of migration intensity for the analysis of the intensity of interregional streams of migration among the 72 oblasts, krays and autonomous republics of the RSFSR, the principal republic of the Soviet Union. The coefficient, which eliminates the impact of the populations of both region of origin and region of destination on the value of the coefficient, is obtained by dividing the shares of all regions of origin in the migration to each region of destination by the shares of the regions of destination in the total population of all regions. The 5112 coefficients of migration intensity are arrayed in a table and subjected to some preliminary analysis of migration patterns. The basic pattern is determined by 171 coefficients with values of 5 or higher, accounting for 3.4 percent of the total number of coefficients.     

WHEELS OF FORTUNE: SUBWAY EXPANSION AND PROPERTY VALUES IN BEIJING

China is experiencing rapid urbanization. Its capital city, Beijing, experienced a 53 percent increase in population from 2001 to 2013. To address traffic congestion and air pollution, two of the most pressing urban challenges, Beijing has been investing heavily in transportation infrastructure. In particular, the subway system added 15 new subway lines with a total length of 410 km of over the 12‐year period. We quantify the capitalization of large‐scale subway construction into property values in a first‐differenced hedonic price framework while controlling for confounding factors and reverse causality. Our analysis finds a positive and significant impact of subway proximity on property values: a reduction in the distance to a subway station by 1 km increases the value of properties within 3 km of the station by 15 percent, and by 3.4 percent for properties within 3–5 km. Our analysis shows that the increase in property values can more than cover the capital cost of subway construction.     

Urban Restructuring of Istanbul

After 1980s, the major cities of Turkey have experienced urban transformation process following the changes in the international trade policy and the impact of globalization. Istanbul took the highest amount of share from these transformation processes as being the most important economic, cultural and tourism centre and the most integrated centre to the world economy of the country. This paper describes Istanbul's historical development, investigates demographic profile and spatial distribution of employment and illustrates multi-centre development of the city. Decentralization of population and jobs illustrate the multi-centre development. Multi-centre development contributes to sustainable urban development which provides efficient energy use and prevents pollution. Istanbul having a long history, large population and being in a very strategic location between Asia and Europe greatly effected from globalization which is reflected in its transformation of urban structure and increased land values and thus offered great opportunities for the real estate investors. The role of Istanbul within the world hierarchy of cities is suggested for further research.
