The share of small and medium-sized enterprises (SMEs) is largely present in forestry, especially in the segment related to non-wood forest products (NWFPs) in Europe. They are also a dominant category in entrepreneurship in Serbia. Therefore, the subjects of this research were the companies operating in the sector of NWFPs, within specific statistical regions of Serbia. The database of SMEs was obtained from 119 SMEs and the share of surveyed SMEs was 81.5%. The main research method was two-step cluster analysis. Questionnaire was used for the purpose of the research. The aim of the research was to identify clusters in order to establish similarities within the defined clusters and the differences among them. Spatial distribution of specific categories of NWFPs in nature (mushrooms, medicinal and aromatic plants, honey and wild berries), contributed to the portfolio of the companies. This largely influenced clusters that are created by categories of products that are typical for certain statistical regions in Serbia.

The article is a continuation of research published by the author elsewhere (Śleszyński, 2020). The elaboration presents the regularity of spatial distribution of infections during the first six months after the detection of SARS-CoV-2 coronovirus in Poland under strong lockdown conditions. The main aim is to try to determine the basic temporal-spatial patterns and to answer the questions: to what extent the phenomenon was ordered and to what extent it was chaotic, whether there are any particular features of spread, whether the infection is concentrated or dispersed and whether the spreading factors in Poland are similar to those observed in other countries. Day by day data were used according to the counties collected in Rogalski’s team (2020). The data were aggregated to weekly periods (7 days) and then the regularity of spatial distribution was searched for using the cartogram method, time series shifts, rope correlation between the intensity of infections in different periods, Herfindahl-Hirschman concentration index (HHI) and cluster analysis. A spatial typology of infection development in the population was also performed. Among other things, it was shown that during the first period (about 100 days after the first case), the infections became more and more spatially concentrated and then dispersed. Differences were also shown in relation to the spread of the infection compared to observations from other countries, i.e. no relation to population density and level of urbanization.

Spatial Analysis Of Crime

Safety is a basic issue in every social system and communities consider safety as one of their main priorities. One of the most important factors that put the safety of various communities at risk is the threats caused by crime occurrence. This paper is aimed to spatially analyze crime occurrence in various regions of Iran with an emphasis on safety. The research method is descriptive-analytical and a documentary and library data collection method is used. In this paper, the Similarity, COPRAS, mean rank method, and cluster analysis method are applied. The final results of the cluster analysis based on the mean rank method indicate a wide gap between the provinces of the country in terms of survey indicators, so that the final coefficient obtained for the provinces in the sixth cluster (the most unsafe group) is about 45 times of the final coefficient of the provinces in the first cluster (the safest group).

Integrated Conservation

Mid Western Development Region (MWDR), a part of Nepali Himalayas, the globally significant and biologically diverse ecosystems, is remarkably rich in medicinal and aromatic plants, and other non-timber forest products (NTFPs). Government recorded data shows that about 700 species of herbal shrubs and NTFPs are found in the region and they are very important natural resources for human beings and for environmental balance. However, these vital and life supporting plants are in threats from deforestation, degradation, overuse and misuse. Unsustainable harvesting, improper storing, unfair trading, common property mismanagement, and policy environments have combined caused such valuable plants to vanish rapidly. The present paper based on empirical evidences points out that without people's participation in resource development, conservation and management it is difficult to enhance the production of locally available resources on one hand, and not possible to reduce the rate of poverty and environmental deterioration on the other. Moreover, the findings of the study emphasize on the need of integrated conservation and development activities through watershed management in order to promote the sustainable livelihoods of people in the region.

The Government

The trading of medicinal and aromatic plants (MAPs) is a traditional means of livelihood in rural areas along the Trans-Himalayan Silk Road and is an important source of revenue for the government of Nepal. Researchers estimate that the officially recorded export value of Nepalese MAPs is many times less than the amount actually exported. MAPs in Nepal are harvested by individuals mostly from the wild and are channelled through intermediate actors within a confusing policy environment. An official permit is required to collect ‘non-timber forest products’ and the Department of Forestry is responsible for regulating the MAPs trade in Nepal by issuing permits and collecting revenue. The hidden economy and informal practices are thus more likely to be used in sectors where permissions are necessary for harvesting, locally transporting, and exporting any commodity.

The purpose of the work is to study the adverse influence of drinkers on the affective status of representatives of their microsocial environment. In four regions of Ukraine (Kharkiv, Lugansk and Zaporizhzhia regions, as well as the city of Kyiv), during 2018—2021, 1742 people were examined, who belonged to three qualitatively different comparison groups: patients with alcohol dependence (AD) (393 people); healthy relatives of alcohol-dependent patients (274 people) and representatives of the general population (1075 people). Of these surveyed, respondents were identified who had drinkers in the environment: 288 persons among healthy people and 121 persons among patients with AD. Further research focused on this particular contingent. The main research tool was the questionnaire of the international research consortium GENAHTO (Gender, Alcohol, and Harms to Others) and Hamilton Depression Rating Scale (HDRS). The obtained data were processed by methods of mathematical statistics (variance and cluster analysis) on a computer using Excel 2016 computational tables (with the Data Analysis package) and also the software package SPSS-15. It was shown that the presence of drinkers in environment of the women significantly increases the proportion of people with depressive disorders among them, while among the male respondents, this effect was not found. It was revealed that the presence of drinkers in environment of the women significantly increases the severity of such manifestations of depression as: insomnia, weight loss, sexual dysfunctions; suicidal tendencies and guilt. Using cluster analysis, the following typical symptom complexes (important for choosing the optimal therapeutic tactics) were established: insomnia-somatoform, hypochondriacal and anxiety-agitational (the latter — with a sense of guilt and an increased risk of suicidal activity).

Forestry Products

In accordance with the principle of sustainable development human population is increasingly returning to nature and its original values. Biodegradable products, products of organic origin are also known as healthy food, medicinal and aromatic plants. Wood and nonwood forest products (NWFPs) are forestry products that satisfy criteria of ecological production and as such appear on the market within small and medium-sized enterprises (SMEs) targeted use of these products, which opens the possibility of developing small and medium entrepreneurship. The aim of this research is the knowledge acquired in a survey of documents relevant for the business of selected enterprises in the Republic of Srpska, from the establishment of enterprises by the Agency for Intermediary, IT and Financial Services to documents applied in purchase, processing and sales of wood and NWFPs. The subject of this study are documents relevant for use in the purchase, processing and placement of wood and NWFPs. The purpose of this paper is to show the business method of analyzed enterprises and present the model of the institutions, procedures and documents referring to wood and NWFPs purchase, processing and placement in the Republic of Srpska.
