AbstractNegative effects of tourism development in a destination are usually the consequence of the high concentration of tourists, accommodation facilities and the activities that are practiced in a relatively restricted area. One of the most important measures to protect the areas is to calculate the maximum number of tourists that can simultaneously reside in a region, i.e. the determination of the carrying capacity. This paper outlines a method for determining carrying capacity based on zoning of environmental resources and zoning within a region. The paper argues for a return to the idea of identifying maximum appropriate number of users. The main hypothesis of the paper is based on the statement that the development of tourism in Fruška Gora (Mountain) National Park in Northern Serbia must be in accordance with the basic principles of sustainability, including the determination of carrying capacity. The main research goal was to show the opinion of local residents about the uncontrolled development of tourism, and to determine the carrying capacity in four sports and recreational zones of the mountain. The carrying capacity of the area is calculated by Lavery and Stanev formulas.

Collusive bidding has been an insidious issue in the construction industry. Bidders initiate collusive networks of various sizes to win market shares. The popularity of collusive bidding networks affects market fairness and erodes the interests of market players. Although considerable research efforts were made to diagnose collusive bidding networks, there remains a gap in knowledge regarding the relationships bid riggers use to engage in the networks. Therefore, this study used the social network method, where two hundred sixteen collusion cases were collected from China to test these relationships. The results show that collusive bidding networks were characterized by sparseness, a small scale, a high concentration, and strong randomness. Three types of collusive bidding networks were also detected: contractual, spontaneous, and shadow. Furthermore, these collusive bidding networks had discrepancies regarding participants’ identities, forms of collusive bids, and the determination of bid winners. It was found that the proposed social network model of deliberating bid riggers’ relationships lays a solid foundation for the detection of collusive bidding in the construction sector.

ABSTRAKPerikanan  tangkap  di  kawasan  Taman  Nasional  Karimunjawa  dikelola  oleh  lebih  dari  satu  instansipengelola.  Setiap  instansi  diduga  mempunyai  peran  masing-  masing  sesuai  tupoksinya.  Saat  ini  belum diketahui secara nyata instansi apa saja yang mengelola beserta perannya. Tujuan penelitian ini adalah untuk mengidentifikasi instansi pengelola yang berperan dalam pengelolaan perikanan tangkap di kawasan TNKJ, persepsi,  aspirasi  dan  partisipasi  nelayan  terhadap  pengelolaan  perikanan  tangkap  serta  bagaimana  strategi pengelola  dalam  pengawasan  perikanan  tangkap.  Metode  penelitian  ini  adalah  studi  kasus  dengan  analisis deskriptif, dimana pengumpulan data melalui wawancara dan studi pustaka. Penentuan responden menggunakan metode purposive sampling, responden terdiri dari nelayan dan instansi pengelola. Hasil penelitian menunjukan bahwa  instansi yang  mengelola  perikanan tangkap adalah Unit  Pelaksana  Teknis   Pelabuhan Perikanan Pantai Karimunjawa, Balai Taman Nasional Karimunjawa, Dinas Perikanan, Polisi Air   dan Tentara Nasional Indonesia Angkatan Laut dan Satuan Kerja Pengawasan Sumberdaya Kelautan dan   Perikanan. Pembagian peran masing- masing instansi pengelola sudah sesuai dengan bidang masing-masing  serta tidak terjadi tumpang tindih kewenangan. Sinkronisasi dan koordinasi sudah dilakukan, hal ini terbukti   dengan  adanya  Nota  Kesepakatan Bersama. Sebanyak 80% nelayan setuju dengan peraturan yang diterapkan. Partisipasi nelayan terhadap sosialisasi dan pelatihan rendah yaitu 35% dan 19%. Strategi pengelola dalam pengawasan perikanan tangkap adalah dengan membentuk dan memberdayakan Pengawas   Perikanan  dan  Kelompok  Masyarakat  Pengawas  secara  sinergi. Strategi untuk  meningkatkan partisipasi  nelayan  dalam  sosialisasi  dan  pelatihan  adalah  dengan  memberikan penyadaran  motivasi dan  apresiasi berupa penghargaan dan pendampingan. ABSTRACTCapture   fisheries   in Karimunjawa National   Park   are   managed by   more   than one   management institutions.  Each  institution  is  assumed  to  have  their  respective  roles  according  to  their  basic  tasks  andfunctions. It is not yet known exactly what institutions are managing along with their roles. The purposes of  this study  were to know what institutions  were involved  in the management of capture fisheries in TNKJ  areas, perceptions, aspirations and participation of fishermen on the management of capture fisheries and  how the management strategy in the supervision of capture fisheries. This research method was case study with descriptive analysis, where data collected by interview and literature study. Determination of  respondents used purposive sampling method, respondents consist of fishermen and manager institution. The results showed that the institutions that managed capture fisheries were Technical Implementation Unit  Karimunjawa Fishery Port, Karimunjawa National Park Office, Fisheries Official, Water Police and Indonesian National Army – Navy and Work Unit of Supervision of Marine and Fisheries Resources. The  division of roles of each institution agency was in accordance with their respective fields and there was no  overlapping authority. Synchronization and coordination had been done, it was proved by the Memorandum of Understanding (MoU). As many as 80% of fishermen agree with the regulations applied. The  participations of fishermen on socialization and training were low at 35% and 19%. The management strategies in the supervision of capture fisheries were by establishing and empowering Fisheries Supervisor  and a group of supervisor community (PokMasWas). The strategies to increase the participation of fishermen in socialization and training were by giving awareness of motivation and appreciation in the form  of recognition and assistance.

Irrigated agriculture has considerable impacts on the environment. To minimize negative effects and maximize positive effects, it is necessary to provide comprehensive analyses beyond the strictly technical domain. In this study, we apply a methodology for determining priorities in implementing irrigation plans using multi-criteria analysis methods on a specific case study area in the sub-catchment area of the Orljava River in Požega–Slavonia County, Croatia. Five potential irrigation areas (Orljava–Londža, Pleternica, Ovčare, Treštanovci, and Venje–Hrnjevac) were analyzed according to five selected criteria: environmental protection, water-related (four sub-criteria), social, economic, and time criteria with different criteria importance (weight). The aim of this study was to confirm the adequacy of using six multi-criteria analysis (MCA) methods (mostly used: PROMETHEE, AHP, ELECTRE TRI, and the less used: DEXi, PRIME, and PCA) in determining priorities for fulfilling irrigation plans, present models for preparation of the input data, apply certain methods, and compare the results on the selected case study area. The methods’ adequacy was confirmed during the research. Five of the six MCA methods identified the Ovčare area as the most appropriate for irrigation development (i.e., it has priority in implementing the irrigation plan). According to one (AHP) of the six methods, Orljava–Londža has more advantages over other areas. All MCA methods, except PCA, chose Venje–Hrnjevac as the least advisable (last to be implemented) alternative. Conclusions from this research confirm findings from recently published research regarding the application of MCA on water management problems.

Over the past decade, the resilience concept has gained great importance in climate change, sustainability, and city disaster researches. To tackle the problem that follows the concept, this dissertation posits a formal theory of resilience. In this sense, resilience provides a semantic reference frame for city risks and disasters. Key terms, which fall under the purview of resilience, are defined. The research problem was crystallized to be formulated as “Our cities of today face many challenges and sudden shocks that are difficult to be predicted,” and “Negligence of the disparities in spatial competence has caused difficult situations to face sudden challenges and shocks to reach the more resilient city.” The aims of this research: 1) to build a conceptual framework for the concept of resilient cities, as well as the determination of spatial competence that has a significant impact on varying levels of resilience in places; 2) to reach a resilient Iraqi city strategy by adopting five more vital areas in Baghdad city. The research hypothesis is as follows: Adopting the presence of spatial competence in the area will facilitate the process of making resilient cities to face risks and sudden shocks. To achieve the research objective, the theoretical framework, built to consist the main research conclusion, was that there is spatial competence and place efficiency in any spatial dimension, which makes it difficult to deal with each place in the same way; every place has its own privacy and accessibility to its best strategies in temporal and spatial dimensions.

Abstract Erosion is one of the biggest and most widely spread forms of soil degradation, having an impact on both the surrounding environment and the economical one as well. According to a recent study from 2014-2015 by the Common Research Center an estimate of approximately 11.4% of the EU’s territory has been affected by the erosion process in moderate to high levels, the soil’s erosion rate being higher than 5t/ha/year. A significant part of Romania’s surface feels the negative effects of the soils degradation, erosion being the most widely spread long-term complex phenomena. Identifying as exactly as possible the areas with erosion risk is recommended in order to intervene with measures of consolidation, leveling, terrain modeling and other hydro-improving constructions. For this reason, for the studied area, Rodnei Mountains National Park (Maramureș County, Bistrita-Nasaud County), having a surface of 47.177 ha, the soil’s erosion has been modeled via the USLE model, developed by Motoc in 1979, taking into consideration all the climate conditions specific to Romania. Following the implementation of the G.I.S environment model, the soil’s erosion estimate values have been obtained, subsequently being divided in 8 classes of erosion, losses of soil less than 0.5t/ha/year representing 89.3% out of the park’s total surface. Researching the model’s obtained results and comparing them to existing values of soil erosion, locally and nationally, we can draw the conclusion that the results of the USLE model are truthful, and that the model can be successfully used in the studied area. Thereby, the study has targeted the determination of vulnerabilities at the erosional processes and vulnerabilities to erosion, the risk of erosion susceptibility being assessed.

Za główny cel badawczy przyjęto ustalenie czy państwa, które powstały w wyniku dekompozycji federacji jugosłowiańskiej, w pierwszym okresie po „usamodzielnieniu się”, były zainteresowane zawiązywaniem współpracy w ramach wspólnych regionalnych przedsięwzięć. Nadto, które z nich wykazały największą aktywność w tym zakresie, a które w stopniu najmniejszym. W związku z tym wzięto pod uwagę „tematyczne” formy współpracy regionalnej w zakresie rozwoju gospodarczego i społecznego, energetyki i infrastruktury, bezpieczeństwa, sądownictwa i spraw wewnętrznych oraz budowania zasobów ludzkich. Jak wynika z przeprowadzonej analizy największym zainteresowaniem cieszyło się partnerstwo na rzecz rozwoju gospodarczego i społecznego, w których wzięte pod uwagę państwa niemal w równej mierze wykazały wzmożoną aktywność, za wyjątkiem Słowenii, która – jak wynika z przeprowadzonej analizy – w stopniu jak najmniejszym była zainteresowana wchodzeniem w tego typu alianse. Podjęty temat jest zbyt mało omówiony, szczególnie w polskiej literaturze przedmiotu poświęconej państwom pojugosłowiańskim, stąd też– w mojej opinii – niewątpliwie potrzebna jest pogłębiona refleksja politologiczna w tym zakresie, namysł nad tymi kwestiami posiada walor poznawczy zarówno dla dyscypliny nauki o polityce i administracji jak też nauk o bezpieczeństwie. Artykuł powstał w głównej mierze przy wykorzystaniu metody badawczej właściwej dla dyscypliny nauki o polityce i administracji – metody studium przypadku. Post‑Yugoslav states – partnership in estabilishing „thematic” regional cooperation The main research goal was to establish whether the states that emerged as a result of the decomposition of the Yugoslav federation, in the first period after „becoming independent”, were interested in establishing cooperation within joint regional projects. Moreover, which of them showed the greatest activity in this field, and which the least. In this regard, ‘thematic’forms of regional cooperation in the fields of economic and social development, energy and infrastructure, security, judiciary and home affairs, building human resources were taken into account. As the analysis shows, the most popular was the partnership for economic and social development, in which the countries taken into account showed almost equal increased activity, except Slovenia which, as the analysis shows, was least interested in participation in such alliances. This topic is too little discussed especially in the Polish literature on the subject dedicated to hence, in my opinion, there is undoubtedly a need for in‑depth political science in this area, reflection on these issues is of cognitive value both for the discipline of political science and administration, as well as security science. The article was written mainly with the use of a research method appropriate for the discipline of political science and administration – the case study method.

This study explores the impact of touristification on the residents of the Seochon and Bukchon areas of Seoul, Korea. Touristification refers to changing an urban space to promote tourism; however, this process displaces the original residents and affects the commercial and social fabric of neighborhoods. We examine the psychological carrying capacity of local residents to adapt to touristification, and present ways to mitigate the negative effects of touristification. First, a semantic differential scale was used to elicit adjectives to assess the carrying capacity of residents to adapt. This was correlated with a classification of the residents’ awareness of the changes. Second, a space improvement index was developed to verify whether an improvement in the physical space will change the psychological carrying capacity of residents. A space improvement simulation indicated the changes in carrying capacity based on the improvement of space. Finally, we established the key factors for each space type and proposed strategies to mitigate the impact of touristification.

Background: Publications on the issues of creating security culture are a valuable source of inspiration for research into the functions of culture. However, researchers generate different conclusions. They even suggest interdisciplinary consideration of facts, situations, phenomena and processes that take place in a complex security environment. This article is an answer to the main research question: what are the functions of the elements of culture for creating a security culture? Objectives: The research goal is to indicate selected definitions of culture and to identify the functions of culture for transformational changes in security culture. Moreover, the author, based on his knowledge and experience, gives examples of the implementation of these functions. Methods: The research process required the use of a critical analysis of the content of the literature, synthesis, abstraction, generalization, interpretation, analogy and comparison. Additionally, empirical case study methods and implicit participant observation were used. Results: The article contains selected definitions of culture with its components. The author presented the functions of culture for creating a high level of security culture. Conclusions: The research results show that the security culture is influencing by the following variables: intellectual culture, emotional potential and ethical culture.
