In this study, number suicides data was used for Turkey’s 81 provinces 2019.The effects factors affecting spatial differences on were analyzed predicted with geographically weighted regression models (GWR). GWR applied different kernel functions, best m...
غلظت ذرات معلق (PM2.5) با وضوح مکانی بالا امکان کنترل دقیق کیفیت هوا را فراهم میکند، بهخصوص برای کلانشهرها که دارای تراکم بالای جمعیتاند. هدف از این پژوهش برآورد ذرات معلق (PM2.5) و روند تغییرات آن در شهر تبریز است. به این منظور، دادههای عمق نوری هواویز (AOD) سنجندههای SeaWifs، MISR، و MODIS طی دورة آماری 1998-۲۰۱۶ برای برآورد PM2.5 استفاده شد. سپس، با استفاده از روش رگرسیون وزندار جغراف...
Objectives. Despite the increasing evidence of the associations between alcohol availability and violence, there are still inconsistent findings on the effects of on- and off-sale alcohol outlets on violent crime. The aim of this study was to examine spatial associations between on-sale alcohol availability, neighborhood characteristics, and violent crime in a geographically isolated city in Te...
In order to better understand the effects of climate change on ecosystems, the relationship between Normalized Difference Vegetation Index (NDVI) and atmospheric constituents have been explored widely by scientists using the global technique of Ordinary Least Squared (OLS) regression analysis. However, recent studies exploring such relationships at different spatial scales have revealed that lo...
The epidemic of lung cancer in Xuanwei City, China, remains serious despite the reduction of the risk of indoor air pollution through citywide stove improvement. The main objective of this study was to characterize the influences of topography on the spatiotemporal variations of lung cancer mortality in Xuanwei during 1990-2013. Using the spatially empirical Bayes method, the smoothed mortality...
African Americans in the U.S. often live in poverty and segregated urban neighborhoods, many of which have dense industrial facilities resulting in high exposure to harmful air toxics. This study aims to explore the relationship between racial composition and cancer risks from air toxics exposure in Memphis/Shelby County, Tennessee, U.S.A. Air toxics data were obtained from 2005 National Air To...
بحث رقابت در خصوص بازدهی فعالیتهای اقتصادی موجود در فضای شهری توجه به مکان استقرار این فعالیتها را در خدمات رسانی به شهروندان بیش از پیش ضروری کرده است. در این بین مراکز مالی و اعتباری، به ویژه بانکها را میتوان یکی از مهمترین فعالیتهای اقتصادی دانست. عوامل گوناگونی در شناسایی مکان بهینه استقرار این فعالیتها دخالت دارد که موجب پیچیدگی در تصمیمگیریهای مکانی میشود و مدلسازی روابط فضایی ع...
In the present study, the main aim was the spatial evaluation summer rainfall of northwest of Iran based on30 stations in northwest of Iran during 30 years of statistical period (1985-2014). An attempt, using geo-statistical modeling by ordinary least squares (OLS) and geographically weighted regression (GWR) procedures, was also made. The results represented that the GWR model with higher S2, ...
This study is concerned with the relationship between transport accessibility and increases in land value, motivated by a desire to inform the land value capture debate. Focusing on residential land, here land value is examined through the form of house prices, using the Tyne and Wear Region of the UK as a case study.

Many major cities in the U.S. and throughout the world, including New York City, have areas where clusters of skyscrapers are present. Why do builders choose to build real estate with such height? And, how does the choice of height depend on characteristics of nearby buildings, demographics, and other spatial factors? Using a data set consisting of detailed information for 458 skyscrapers in Ne...
