This study apprises the local and global implication of ambient air quality index of Kaduna Metropolis, Nigeria. With the point of investigating the spatial and transient dissemination of the Air Quality Index (AQI) of Carbon monoxide (CO), Sulfur dioxide (SO2), and Particulate Matter (PM10) and their suggestions on human wellbeing, in view of neighborhood and global measures. Data were collected during the raining season and dry harmattan weather. From traffic, Industrial, commercial and residential areas, utilizing validated portable pollutant monitors (MSA Altair 5x Gas Detectora) to collect data on the concentration of air pollutants (CO and SO2) and (CW-HAT200 Particulate Counter) for the concentration of particulate matters (PM10). Equal allocation stratify sampling and purposive sampling were utilized for the selection of sample points. The data were analyzed in line with USEPA Air Quality Index calculation approach and using descriptive statistics. The findings reveal that the AQI of Kaduna Metropolis ranges from good to hazardous, CO has 57.57% and 24.24% of the sample sites AQI ranging from unhealthy to hazardous based on WHO/USEPA and NESREA standards respectively. Equally SO2 has about 91%, 34.23%, 42.42% of the sites AQI ranging from unhealthy to hazardous base on WHO, USEPA and NESREA standards respectively. PM10 has 75.76% and 18.18 of the sites AQI as hazardous base on WHO and USEPA standards, whereas none of the sites AQI is hazardous base on the NESREA standard. Further analysis shows that the northern part of the metropolis has more sites with unhealth AQI than the southern part of the metropolis. Also, the traffic land use has more of its sites AQI ranging from unhealthy to Sensitive group to hazardous. In conclusion this study provides empirical data on the AQI of Kaduna metropolis which ranges from good to hazardous. Thus, the need for the enforcement agencies to strictly enforce the guide lines regulating ambient pollution in the study area.

The set of phenomena related to recreational activities should be considered as a system, so that the object of study of recreational geography is the Territorial Recreational Systems (TRS). The main social function of TRS is to maximize the needs of the population in recreation, health, treatment and increasing physical and spiritual potential. TRS is an open system, it receives information, matter, energy from the external environment. TRS transmits to the external environment, mainly, information for the management of the supersystem and the so-called recreational information for the population (potentially aggregated by tourists) and, most important, it returns the tourists themselves - people after rest, healthy and spiritually enriched. Studying the models of development and functioning of the Territorial Recreational Systems (TRS) is inextricably linked to the problem of identifying the relationships between the individual elements of this system, such as tourists, natural complex, technical structures, servi ce system) and between recreational and non-recreational systems (reinstallation) etc.

This article presents the issue of contemporary urban dynamics, wherein urban sprawl occupies a central position. The post-Fordist city, an expression of individual initiative and piecemeal projects, decidedly favors this phenomenon, on the background of a constant rise in the social demand for individual housing. Faced with this new trend of extensive development, it is necessary to find ways of conciliating the categories of actors responsible for “creating the city”, in the spirit of a sustainable, medium and long-term urban development, done, as far as possible, in the manner of an integrated approach. The perspective of the fractal modeling performed using the MUP City computer software may constitute an instrument which can be used in this context, putting forward a fractal reinterpretation of the principle of the garden-city.

The aim of this paper is determination of the City of Zaječar settlements’ functional organization characteristics significant for development of primary rural settlements on this territory. The paper examines truthfulness of a hypothesis that in conditions of extreme monocentrism, i.e. dominance of urban centre, development of primary rural settlements is in direct negative correlation with isochronous distance from the urban center. Secondary hypothesis is an assertion that primary rural settlements functionally connected to centers of communities of settlements as dispersly located microdevelopment centers are characterized by significantly more favorable development compared to settlements functionally connected to local rural centers or directly to the urban center. Methodologically, the paper is based on the comparison of development characteristic of primary rural settlements relative to their isochronous distance from the urban center and functional connections to higher rank settlements in the functional hierarchy. Selection of indicators was made in order of comprehensive representation of the most significant demographical and economical processes in these settlements caused by their geographical and functional positions. Perception of the significance of the isochronous distance from the urban center was made using Pearson correlation coefficient, and the method of comparison was used for the functional connections. The significance of this paper is in contribution to the insight of applicability of decentralized concentration concept on local territorial level in conditions of extreme monocentrism, i.e. dichotomy on relation rural-urban.

Florian Porcius, an academic, was born into a family of Nasaud bourder guards. He spent the most of his professional and personal life in the Năsăud County, a location that drew him in and to which he devoted himself wholeheartedly. Among his many trades and occupations (judge, teacher, administrative position) that of botanist stands out. Florian Porcius did not have a formal botany education, yet he was a brilliant self-taught botanist. Beginning in 1849, he will devote himself to this profession, eventually collecting and processing over 20,000 plant specimens. He will make frequent scientific expeditions in the Rodna Mountains, collecting and processing a wide variety of flora. The academician Florian Porcius’ plates are now part of the „Muzeul Grăniceresc Năsăudean” collection. Over 300 plates have been identified and inventoried so far. The procedure will be repeated until the entire collection has been documented. Our goal is to showcase the collection’s historical significance as well as its exhibition quality in a thematic display curated by the author.

In the year 1882 when the first power plant designed by Thomas Edison began operations in Wisconsin, United States, the price of fuels was little more than symbolic and there was no knowledge about the environmental damage caused by the energy exploitation of fossil fuels. Currently the situation is completely different, with an unstable and expensive oil price, as well as an environmental awareness forged in the consequences of the over-exploitation of natural resources, the structuring of a sustainable energy matrix constitutes a challenge that is sustained in the use of renewable energies available territorially. For this, it will be necessary to bring the techniques and tools of territorial planning closer to the tasks of energy development, on the basis of achieving adequate planning of the space for the use of the endogenous energy resources of the territories. The objective of the work consists of proposing the application of a methodology for the study of the application of renewable sources, starting from determining the viable physical areas for their introduction, applying techniques of land use planning through a GIS. The Isla de la Juventud is a special municipality of the island of Cuba with significant renewable potential, however, the limitations inherited from traditional development models restricts the sustainable development of the territory from being achieved. In the period from 2010 to 2014, two projects were carried out to contribute to the diversification of the energy matrix, through the application of a territorial energy development model. This article takes up the main results of these projects, considering that they are currently valid. In this sense, an analysis of the energy matrix on the Isla de la Juventud was carried out at present and the projections until 2030, from a perspective of land use planning; with the aim that can get constituted as a guide for organization and planning of the integrative process of the renewable energies, in the diversifying process of the energetic matrix of Cuba.

This research paper on the topic: "Information systems management controls with reference to geographic information systems" will explore: (1) information systems management, (2) geographic information systems, (3) information control aimed at reducing the probability of an adverse event and reducing the expected losses that would occur in the occurrence of undesirable processes in the observed system, (4) the quality of business information systems is manifested in equality with the product of the level of quality of each individual component (hardware, software, hardware, netware and orgware) and (5) management of information systems development. This will be investigated by the method of content analysis, while the paper will present models using the scientific method of modelling and the application of modelling rules. The research will present the costs of GIS that fall on data entry and the cost of data entry. Also, views on information systems as a term will be explained, namely: technical view, social view, socio-technical view and view of the process. This paper as a whole is classified in this context on the socio-technical point of view for the reason that GIS is classified according to the technical point of view while MIS is classified according to the social point of view.

Nowadays society is becoming increasingly dependent not only on access to the Internet, but also on its quality, assessed by the speed of data transfer. Therefore, identify regularities in this regard particularly in spatial terms is an important issue both from cognitive and application point of view. The aim of the study is to identify the spatial differentiation of the Internet quality on a local scale in Poland. This phenomenon is considered in the context of digital divide, on two levels of interpretation: symmetry of Internet access and its substitution. The basic source of data used in the study is crowdsourcing data generated by Internet users via Ookla’s Speedtest tool. The data allow to determine the real – experienced by the users – speed of the Internet. As a result of the analysis of the typologies for municipalities prepared in the study, several regularities were identified with regard to the digital divide. Firstly, in the case of the Internet performance, the core-periphery dimension is not universal and obvious, as regional patterns are strongly visible. Secondly, looking at digital divide mainly through the lens of Internet access is definitely an insufficient approach in this research area.

The first twenty years of the 21st century, especially its second decade, was a period of dynamic growth in the number of transport geographers PhD promotions. The situation with independent academics (in Polish scientific system habilitated doctors and professors) was much worse. There was no such strong dynamics of the development of new staff as in the case of completed PhD procedures. Only one of habilitated doctors promoted in the analysed period is currently working as an associate professor, next one has quit Polish science, but the others have successively obtained professorships. A strong spatial polarization of the places where promotion procedures were carried out was also visible. The PhD processes were carried out by 11 institutions, but nearly 4/5 of them took place before the scientific councils of six of them. At the same time, almost 1/3 of the promotion took place at the Institute of Geography and Spatial Management of the Faculty of Biology and Earth Sciences of the Jagiellonian University and the Institute of Geography and Spatial Organisation of the Polish Academy of Sciences (IGSO PAS). Additionally all habilitation procedures in the field of transport geography were completed in IGSO PAS I. The article points out that the current age structure of researchers of the sub-discipline is quite favourable, while its distortion in terms of research degrees and titles is worrying, where the group of habilitated doctors is disturbingly small, which means that a significant distortion of the pyramid reflecting it is visible. In the future, this may result in problems of the succession of generations.

Despite the fact that urban areas have existed for millennia, no single, universal, supranational, and fully accepted definition of a city/town has been developed to date. The aim of this article is to review the criteria for identifying cities/towns in the world and their spatial differentiation. 233 territorial entities that are sovereign states or territories belonging to other states were surveyed. The analysis was based on a query from a list provided by the Department of Economic and Social Affairs of the United Nations Population Division, which contains the definitions of cities/towns adopted by individual countries or territories when collecting data in censuses. The research carried out shows that singleor multicriteria definitions, referring to quantitative or (and) qualitative elements from the group of legal-administrative, demographic, infrastructural-spatial, and functional criteria, are most often used to distinguish cities/towns from villages. More than half of the surveyed territorial entities use only one criterion mentioned, and this is usually a legal-administrative criterion or a demographic criterion. In the process of identifying cities/towns, just over two-fifths of the surveyed entities apply a minimum population threshold (as the only or one of many criteria), set most often at 2,000 or 5,000 inhabitants. East Africa is the most diverse region in the world in terms of the criteria adopted, while Central Asia, Australia, and New Zealand are the least.

The article interprets Velebit as a space of peripatetic literature beginning, naturally, with Petar Zoranić’s Planine (written in 1536 and published in 1569) wherein, in addition to a personal psychogram on conventional lovesickness (“beteg”), the author problematizes the general situation in his “scattered heritage” (“rasuta bašćina”) (under Ottoman and Venetian threat). As opposed to Zoranić’s imaginary voyage formulated as an allegorical voyage of enlightenment along the paths of Velebit, Edo Popović, in his trans-genre Priručnik za hodače (The Walkers’ Manual) (2009), 440 years after Zoranić (to introduce some symbolism), with his zen-roamings in Velebit and his principle of “voluntary poverty,” as mirrored in Henry David Thoreau’s ecological matrix, equally discloses sociograms of not only “scattered heritage”, but of the global world order, as well. The trilogy of travel writings, of this hiking literature by Edo Popović, can be defined as peripatetic literature about Velebit. Yet it has to be stressed that these are travel writings, namely hiking literature with an engaged attitude toward reality.

Lithuanian teenagers are considered to be the most unhappy in the Europien Union. Also when comparing with other countries in Europien Union, suicide rates of children and teenagers are one of the highest in Lithuania. The main goal of this article is contribute to psychology geography and to research one of the most vulnerable social groups in Lithuania. One of the factors that influence the emotional well being of teenagers is their geographical environment. This article reviews the research of children and teens well being in the world and in Lithuania, the definition of psychology geography is also analysed. First part of the article describes the geographical environment in Raudondvaris eldership, the main focus is on nature and social elements, which contribute to ones emotional well being. It is important to note that two types of environmental elements are described: material (nature, infrastructure and other) and nonmaterial (communities, activities in elderships organisations and other). Second part of the article describes the connection between the teenagers well being and their environment. This analyses is done by conducting a survey. Most respondents (89%) think highly of their geographical environment. Positive evaluation is seen in the center of the eldership and in the smaller villages. Emotional well being indicator was taken from the recommendations of the World Health Organisation. Most teenagers living in Raudondvaris eldeship had scored high in this indicator (only one forth scored low). These results are influeced by good naturalistic environment and semi active social lives, good connection with bigger cities near by, where teenagers can engage in services and free time activities. This research has revealed, that teenagers living further away from the elderships centre feel much better then those living in Raudondvaris village. This can be explained, that most of the elderships territory is a suburb of Kaunas city. In this case distance from the city centre does not impact emotional well being of teenagers in Raudondvaris eldership. Well developed infrustructure and Kaunas city allows teenagers to take adventage of services that Kaunas city has to offer.
