Opis:
Bibliometric analysis is a research method that is used to identify research gaps and the potential paths of empiric exploration of such categories that seemingly have been studied, but which in which enormous scientific and utilitarian capabilities remain undiscovered. Sustainable development is one such category. The purpose of this article is to present the development and evolution of scientific literature on sustainable development, and the research goal is to forecast the developmental directions for this category. Bibliometric analysis was used in the research. Scopus, the international interdisciplinary database, was the data source. Maps of co-occurrence of keywords relating to sustainable development were prepared in VOSviewer ver. 1.6.19. The results of the research provided new and crucial knowledge about the features of contemporary literature on sustainable development, determined following analysis of the content of selected open access journals that are representative for this field. The chronological aspect of research of the concept of sustainable development was also underlined. This, in the context of management development, resulted in essential conclusions and results pointing to the potential directions of development of the analysed area. The results also identify the key publications and journals for the subject being researched. This is one of the few works which features a comprehensive bibliometric analysis of sustainable development (Díaz-López et al., 2021; Nobanee et al., 2021; Yamaguchi et al., 2023; Zhu & Hua, 2017). The added value of the analyses is the information that was prepared in the form of rankings using bibliometric indicators such as the number of citations, number of articles cited, and the map of co-cited journals.

Opis:
The purification of microplastic samples is a crucial step in environmental research, aiming to remove contaminants and ensure accurate analysis. This study explores various methods for purifying microplastics, focusing on the removal of organic contaminants, specifically fulvic acids. Comparative analysis using microscopic imaging techniques was conducted to evaluate the effectiveness of these methods. The results highlight the complexities involved in microplastic purification and the challenges associated with different approaches. While some methods showed promising outcomes, such as the sonification method, it was also observed that they could potentially alter the microplastic structure. Additionally, the limitations and potential interferences of other purification methods, such as Fenton's solution, were identified. This study underscores the importance of selecting purification methods that minimize negative impacts on microplastics and ensure reliable analysis. Further research is needed to optimize purification techniques and fully understand their effects on microplastic integrity. This research contributes to the broader goal of developing robust methodologies for microplastic analysis in environmental studies.

Opis:
In Poland there are over a dozen bodies engaged in protection of environment. The tasks in the field of combating environmental crime are carried out by several institutions with varied duties and control and investigative powers, including appearing before trial court. The system of law enforcement institutions engaged in environmental protection is undoubtedly dispersed. There is no agency legally entitled to coordinate or influence the activities undertaken by other institutions within the system. The main role here is undoubtedly played by Environmental Protection Inspectorate. It was tasked with both monitoring of compliance with the environmental protection regulations in a very wide scope, as well as independent conduct of certain operational activities and granted investigative powers. The role of the Environmental Protection Inspection will increase in the future, as evidenced by the establishment in 2021 of the Department for Combating Environmental Crimes at the Chief Inspectorate for Environmental Protection. So far, the vast majority of investigations concerning environmental crimes are conducted by the Police. There are, however, no specialised police units fighting environmental crimes and corresponding activities are carried out by departments combating economic crimes. Cases concerning organized forms of environmental crime are conducted by the Central Investigation Bureau of Police. No coherent strategy to combat environmental crime has been developed so far. Cooperation between various involved institutions is based on bilateral and multilateral agreements. An undertaking necessary to improve the effectiveness of combating environmental crimes is currently primarily the creation of common database of these crimes mechanisms and perpetrators, as well as creation of an analytical structure dealing with this issue,

This study analyses the relationship between tolerance to ambiguity, environmental perception, authentic leadership and performance in SMEs. In order to test the above, information is collected from 285 entrepreneurs and through a combination, the mediation analysis is applied with the moderation of the direct effect of tolerance to ambiguity on performance through the environmental perception, as well as an effect on the relationship between the mentioned variables is determined directly, which is a function of authentic leadership. The authors found that tolerance to ambiguity and authentic leadership were positive predictors of environmental perception, which in turn positively impacted performance in SMEs. Additionally, the study revealed that the relationship between tolerance to ambiguity and performance was mediated by environmental perception. Overall, the study provides valuable insights into how the interplay of various factors can impact SME performance outcomes and suggests that enhancing tolerance to ambiguity and authentic leadership can lead to improved environmental perception and, ultimately, better performance for such businesses.

Opis:
Laboratory and industrial studies have established the total impact of environmentally hazardous substances, taking into account the distance from the source of emissions and the specific consumption of explosives. With the help of physicochemical analysis and biological testing, the dependence of the change in the conditional indicator of damage to bioindicators with an increase in the distance from the source of emission and the specific annual consumption of explosives was revealed. A methodology for calculating the environmental assessment of the state of atmospheric air around the mine ventilation shaft has been developed. The exponential dependence of the influence of surface concentrations of environmentally hazardous substances on the damage of bioindicators at the cellular and organismic levels has been established, which makes it possible to assess the state of atmospheric air at industrial sites of iron ore mines. The proposed technology of sand drilling, which involves the use of emulsion explosives in mining ore deposits in chamber development systems will reduce emissions of environmentally hazardous substances into the atmosphere and increase the level of environmental safety of iron ore mines.

Opis:
EU Biodiversity Strategy for 2030 aims to restore 25,000 km of free-flowing rivers across Europe. The critical issue is which barriers should be prioritised for removal. In this study, a set of socio-economic and environmental criteria was chosen to rank the dams on salmonid rivers in Lithuania and recommend them for removal. As these criteria usually contradict themselves, the multi-criteria decision analysis tool was utilised. The results showed that the Anykščiai dam on the river Šventoji could be recommended to be removed first. The removal can significantly increase the salmonid population in the river Šventoji over a significant stretch of the river. Also, this dam is in a protected area, is not listed as a national heritage, and does not have a hydropower plant. Although, this study showed that dams with hydropower plants could also be recommended for removal.

Opis:
The leather production from paiche skins (Arapaima gigas) has recently grown in Peru, as this allows adding value and earnings from this Amazonian aquaculture waste. The development of this process requires that the tanning techniques could preserve environment as these are meant to take place in Amazonian zones. The present study evaluated the environmental performance of two chrome-free tanning techniques of paiche skins compared with traditional chrome tanning technique, developed at pilot scale by CITEccal Lima. The evaluation was carried out using environmental performance indicators (EPI), analyzed and compared using the grey clustering method, identifying coefficients (σ) respecting to the stablished classes in the study (λ1 – good, λ2 – regular, λ3 – deficient). As result, the two chrome-free tanning techniques showed a better environmental performance than the traditional chrome tanning technique (σ – 0.54, class λ2). The optimized tanning technique applying phenolic compounds had the best environmental performance (σ – 0.98, class λ1), and its values for each environmental performance indicator per 1000 kg of initial processed paiche skin were: 30.0 m3 for water consumption, 815.0 kg of chemical products applied, 2022.7 kWh for energy consumption, 105.5 kg of solid wastes; and from wastewater characterization: 2780.9 mg/L for BOD, 11682.9 mg/L for COD and non-detectable chromium. On the basis of these results, its transfer is recommended, including a wastewater treatment system and environmental management measures implementation.

Opis:
The paper refers to the research Trash in the Wild: A Pilot Project Mapping Citizenship Environmental Activism in the Collaborative Study in the Lodz Area. In the study, inhabitants of Lodz (Poland) were invited to participate in data gathering and create a map of unauthorized dumps in their city. The collaborative mapping was intended to localize problematic spots in the city of Lodz, but it also shows civic commitment and the inhabitants’ ecological consciousness level. The authors based on ethnographic data (observations, walk-alongs, interviews, and data obtained from institutions), attempting to develop a situational analysis of the phenomenon of illegal dumps in the city. The analysis reveals how different positions of the City Guard, Municipal Economy Department, waste disposal companies, journalists, environmental activists, researchers, and citizens participating in the project vary their standpoints and views on the studied problem. Presenting the context and first results of the research, the authors refer to the issue of building relationships with researched subjects during the investigation process. Trying to navigate between them, researchers strive to introduce their different, sometimes contradictory, viewpoints into the research, not losing their commitment and the valuable data they can submit. The analysis shows that the issue of illegal dumps lies at the intersection of many discourses and involves numerous social worlds, organizations, and entities. In this dynamic situation, many practices and conditions contribute to the persistence of the problem of illegal waste disposal.

Purpose: The aim of the article is to evaluate and characterize the use of renewable energy sources and their impact on the environment in selected European countries. Design/methodology/approach: relying on renewable energy sources is one of the fundamental goals of the European Union, which is constantly striving to improve the quality of life of societies, and to secure the welfare of present and future generations. The authors performed an analysis of energy consumption in 2010-2020 based on statistical data obtained from the European Statistical Office “EUROSTAT”. Numerous statistical analyzes, including data composition and decomposition, have been carried out. The authors relied on the analysis of change dynamics technique. The article presents indexes with a variable base (chain) and relative increments with a constant base. Findings: It has been established that the use of renewable energy in the following analyzed sectors such as electricity, transport, heating and cooling is diversified, with the highest use being noted in the field of heating and cooling. The most developed country in Europe in terms of the use of renewable energy sources is Iceland, followed by Norway and Sweden. The countries with the lowest use of renewable energy are Malta, the Netherlands and Luxembourg although these countries are exhibiting a growing tendency towards using renewable energy sources. Originality/value: The article presents the results of data composition regarding the use of renewable energy and its impact on the natural environment. Due to the analyzes used, it may be regarded as an interesting overview of the use of renewable energy sources.

Opis:
Economic growth and development are connected with the increase in consumption. One of the side effects of progress is waste production. Sustainable development would also include proper management of waste, focusing on their recycling. However, the direct costs of recycling sometimes exceed the costs of waste storage. Therefore, waste storage in landfills is still widespread. Improper waste storage or deliberate actions can lead to waste fires. In the work, the statistics of landfill fires from the years 2012 to 2021 were analyzed. The work includes statistics of the parameters of fires reported in the reports of Polish State Fire Services. Additionally, the usage of the resources and materials for firefighting and their trends were discussed. It was shown that resources required for extinguishing waste fires were increasing in this period. The statistics are accompanied by spatiotemporal analyses of the location of fires based on Corine Land Cover which showed that approximately half of the fires are on arable land and non-continuous urban fabric while fires at dumpsites are relatively rare. The important concern is also that around 10% of very big waste fires are in forests. All these analyses lead to the assessment of some environmental impacts which are caused by waste fires.

Opis:
This paper is focused on some of the possibilities of the use of cluster analysis (clustering) in criminology and the sociology of law. Cluster analysis makes it possible to divide even a large dataset into a specified number of subsets in such a way that the resulting subsets are as homogenous as possible, and at the same time differ from each other substantially. When analysing geographical data, e.g. describing the location of crimes, the result of cluster analysis is a division of a territory into a certain number of coherent areas based on an objective criterion. The division of the territory under study into smaller parts is more insightful when the clustering method is applied compared to an arbitrary division into official administrative units. The paper provides a detailed description of hierarchical cluster analysis methods and an example of using the Ward’s hierarchical method and the k-means combinational method to divide data on crime reports in the city of Baltimore between 2014 and 2019. The analysis demonstrates that the resulting division differs considerably from the administrative division of Baltimore, and that increasing the number of groups emerging as a result of cluster analysis leads to an increase of variance of variables describing the structure of crime in individual parts of the city. The divisions obtained using clustering are used to verify the hypothesis on differences in crime structure in different areas of Baltimore. The main aim of the paper is to encourage the use of modern methods of data analysis in social sciences and to present the usefulness of cluster analysis in criminology and the sociology of law research.
Prezentowany artykuł poświęcony jest wykorzystaniu w socjologii prawa oraz kryminologii środowiskowej jednej z nowoczesnych metod obliczeniowych przydatnych do badania dużych zbiorów danych – analizy skupień (grupowania; klasteryzacji). Metoda ta pozwala na podzielenie zbioru obserwacji na ustaloną liczbę podzbiorów takich, że elementy tego samego podzbioru są do siebie możliwie podobne, a elementy różnych podzbiorów – możliwie odmienne. Jeśli dane dotyczą położenia geograficznego, na przykład umiejscowienia przestępstw, rezultatem wykorzystania analizy skupień będzie podział obszaru na ustaloną liczbę wewnętrznie spójnych rejonów według zobiektywizowanego kryterium. Podzielenie badanego terytorium na mniejsze części tradycyjnie, w dużym stopniu arbitralnych, takich jak na przykład podział administracyjny. z zastosowaniem klasteryzacji wydaje się być lepszym rozwiązaniem od kryteriów stosowanych W pracy przedstawiono szczegółową charakterystykę hierarchicznych metod analizy skupień, a następnie wykorzystano metody kombinatoryczną k-średnich oraz hierarchiczną Warda do podziału zbioru danych o zgłoszeniach przestępstw w mieście Baltimore w latach 2014–2019. Wykazano, że powstały w ten sposób podział różni się w sposób znaczący od podziału administracyjnego Baltimore, a także że zwiększanie liczby grup powstających jako wynik analizy skupień prowadzi do pożądanego w pewnych przypadkach wzrostu wariancji zmiennych opisujących strukturę przestępczości w poszczególnych częściach miasta. Utworzone przy użyciu klasteryzacji podziały wykorzystano także do zweryfikowania hipotezy o odmienności struktury przestępczości w różnych obszarach Baltimore. Głównym celem pracy jest zachęcenie do stosowania w badaniach społecznych nowoczesnych metod analizy danych oraz pokazanie, że analiza skupień może być cennym narzędziem w kryminologicznych i socjologicznoprawnych analizach poświęconych relacji między prawem a przestrzenią.

Opis:
In pursuance of the Saudi vision 2030, the Al-Hasa municipality has been allocating a total of US$ 60.1 million since 2018 to the implementation of a modern Municipal Solid Wastes (MSW) management system. In addition to the improved old components, the system involves six new-engineered cells, five of which will be gradually implemented in progresses, two waste sort-out lines station, and LFG energy recovery. The present research aimed at investigating the environmental and economic impacts of this MSW management system. For this purpose, the authors applied the Life Cycle Analysis (LCA) and Life Cycle Costs Analysis (LCCA) approaches. The main results showed that the air quality was not affected. For instance, gas emission, like carbon monoxide, was less than 0.1 ppm. However, soil and groundwater were contaminated due to leachate infiltration from the uncontrolled cell in which Chloride, Nitrate, and Sulfate exceeded the maximum limits. As for noise, it was found to be high near the sorting-out station at 71.1 Leq dBA. In terms of the financial aspect, the improved MSW management was relatively feasible despite its high costs over its revenues. Thus, the negative cash-flow could be supplemented by setting household taxes at US$ 29 per capita per year, which makes the project cost-effective. Thus, the research recommends continuing the MSW management project.

Opis:
This study aimed to examine the relationship between environmental facilities as risk factors and crime. Police data of property and violent criminal offences registered during 2018 in the city of Niš, Republic of Serbia, has been geocoded. Grid cells of 100 by 100 meters were designed as spatial units for the analysis, and geoinformation data of 12 different facilities were extracted from GIS. The negative binomial regression model was constructed to investigate crime risky facilities. The crime is mostly related to facilities as banks and exchange offices, bus stops, gyms and recreational centers. On the other hand, cafes, nightclubs, and big shopping centers were not significantly associated with crime. Finally, limitations, practical and theoretical usage of the research are discussed.

Prezentowane badanie ma na celu analizę relacji przestrzeni i obiektów w niej rozmieszczonych oraz przestępczości. W analizach wykorzystano dane policyjne o przestępczości zarejestrowanej w 2018 roku – czynach przeciwko mieniu i z użyciem przemocy popełnionych w mieście Niš w Serbii. Dane te zostały poddane geokodowaniu, względem miejsc zdarzeń przestępczych. Jednostką przestrzenną była komórka siatki o wymiarach 100 na 100 metrów. Dane geoinformacyjne o 12 rodzajach obiektów uzyskano za pomocą oprogramowania GIS. Celem zbadania związku między wybranymi obiektami a przestępczością wykorzystano model regresji dwumianowej. Wyniki przeprowadzonych analiz pokazały, że przestępczość występuje najczęściej w przestrzeniach, w których mieszczą się banki, kantory, znajdują się w niej przystanki autobusowe, restauracje, siłownie czy ośrodki rekreacyjne. Nieistotny statystycznie z kolei okazał się związek między występowaniem przestępczości a rozmieszczeniem takich obiektów jak: kawiarnie, kluby nocne czy duże centra handlowe. W artykule zostały omówione także ograniczenia oraz praktyczne i teoretyczne możliwości zastosowania przeprowadzonych analiz.

Opis:
A large portion of the credits and financial resources of countries is spent on the preparation and construction of building projects because their implementation would create housing, job opportunities, financial turnover, and economic prosperity. At present, many construction projects are under construction in developing countries, and most of these projects are facing rising costs. The local scope of this research is construction projects in Yazd city. This research is operational in terms of purpose and was carried out in a descriptive and survey manner with an analytical-mathematical method. Data collection was done by documentary and survey methods. The Statistical Society consisted of 150 managers and officials, contractors, and actors involved in construction projects. Data analysis by hierarchical analysis technique showed that the criterion of management factors with a weight of 0.582 has the highest priority in increasing building costs. The criterion of environmental factors with a weight of 0.309 is at the second priority. The criterion of legal and administrative factors with a weight of 0.109 is in the third priority. Therefore, a key element in increasing the cost of construction projects in the under-studied city is the management factor that can be reduced by establishing new management systems and improving the quality of construction projects.
