Abstract
An attempt has been made to compare the salient characteristics of LULC transformations in planned (Faisalabad) and quasi-planned (Jhang) urban settlements of Pakistan. The Landsat-5 TM, Landsat 7 EMT+ and Landsat-8 images of 1989, 1999, 2009 and 2019, respectively, were retrieved and processed through google earth engine. The dynamics of LULC critically analyzed for the three periods 1989–1999, 1999–2009 and 2009–2019. The LULC analyzed in terms of quantity of change, gains, losses, and persistence of the study area examined carefully. The study mainly focuses on the LULC transformations of the previous 30 years (1989–2019). These 30 years witnessed massive physical expansions and LULC convergences. During this time interval, the built-up areas in these cities expanded, and productive agricultural land substantially squeezed. The spatialtemporal analysis of LULC changes calls for improvised strategies for the resilience of land and environmental resources. The direct beneficiaries of this research are resource managers and regional planners as well as others scientific community.

Abstract
Continual, historical, and precise information about the land use and land cover (LULC) changes of the Earth’s surface is extremely important for any kind of sustainable development program, in which LULC serves as one of the major input criteria. In this study, a supervised classification was applied to five types of Landsat images collected over time (1980, 1990, 2000, 2010 and 2015) that provided recent and historical LULC conditions for the area. Four LULC categories were identified and mapped. Post-classification comparisons of the classified images indicated that the major change consisted of barren land changing into agricultural land. This analysis revealed that substantial growth of built-up areas in the south eastern part of Kolkata over the study period resulted in significant decrease in the area of water bodies, cultivated land, vegetation and wetlands. Urban land transformation has been largely driven by large number of population and high population growth rate with rapid economic and infrastructural development like the extension of metro railway, flyovers and hence huge real estate development.

Abstract
The article aims to present social ties of the Republic of Bashkortostan based on voice cell phone data, which covers 12 million calls from and to the region during the first five days of March 2020. About 96% of calls are made within the republic and only 4% of them are interregional. The people of the Republic of Bashkortostan have close connections with those who live in neighboring regions (Orenburg, Sverdlovsk oblast, the Republic of Tatarstan and especially Chelyabinsk oblast). Being a part of the Ural Economic Region, the Volga Federal District and Volga-Ural Macro Region, the republic has turned mostly towards Ural regions. We also found that the republic has close social ties with Moscow and Moscow region, St. Petersburg and Leningrad oblast, as well as Krasnodar kray, Samara oblast and two Autonomous Districts: Khanty-Mansi and Yamalo-Nenets. We estimated the number of persons who possessed Bashkir SIM-card and were outside the republic during the research period – 183 thousand; the most of them were in the abovementioned regions. While conversation between residents lasts 50 seconds, which is among the smallest values, the calls to and from republics of Altai, Tyva, Khakassia, Sakha and Magadan oblast are 5-8 times longer. Overall, the communication pattern reflects migration flows and economic relations between regions. The results of this study can be utilized by researchers and Bashkir government to explore spatial interaction patterns between regions and may help to guide transportation planning and other potential applications, e.g. infrastructure construction projects. In conclusion, we postulate that cell phone data can be exploited as a source of social ties data, however, the strengthening communication shift into Internet space is diminishing information on the directional features of the ties.

Abstract
During the period of planned economies in Russia and Poland, services were underestimated as a sector of economic activity. To some degree, this continues to be the case. In spite of the existence of market economies in Central and Eastern Europe for more than 25 years, Russia and Poland should be categorized differently in terms of economic and social development. Based on D. Bell’s and his followers’ (M. Castells, A. Toffler, J. Rifkin, P. Drucker) theory of post-industrial society and post-industrial economy, Poland can be classified as a post-industrial country, while Russia is still an industrial country in many aspects. This point of view is based on global statistics and cross-country comparisons. The following statistical data has been used as a source for this research: share of services in GDP by country, contribution (value added) of seven main types of services to the respective GDP of Russia, Poland and other selected countries, value added and governmental expenditures per capita of primary services in aforementioned economies. The main differences between the Russian and Polish service sectors are indicated. The cases of Russia and Poland are presented here to highlight the key common features of Central and Eastern European countries’ tertiary sectors.
