Celem artykułu jest naświetlenie problemów rozwoju europejskiego przemysłu obronnego oraz prób jego reformowania. Prezentowany tekst został opracowany na podstawie dokumentów Europejskiej Służby Działań Zewnętrznych, w strukturach, których funkcjonują między innymi: Sztab Wojskowy UE oraz Europejska Agencja Obrony. W 2017 roku powołano kilka instytucji, które miały na celu modernizację oraz integrację kilkuset rozproszonych europejskich przedsiębiorstw zbrojeniowych i wyposażenie ich w konkurencyjne technologie. Ważną rolę w tej dziedzinie odgrywają Europejski Fundusz Obrony oraz Roczny Skoordynowany Przegląd Obronny (CARD). W 2022 r. procesy integracyjne w dziedzinie obronności zostały przyspieszone z powodu agresji Rosji przeciwko Ukrainie, a także po przyjęciu nowej strategii bezpieczeństwa Unii Europejskiej zwanej „Kompasem Strategicznym”. Europejska Agencja Obrony opublikowała także rezultaty i wnioski CARD 2022.

The aim of the article is to highlight the problems of development of the European defense industry, and the attempts to reform it. The presented text was prepared on the basis of documents of the European External Action Ser-vice, in the structures of which they function, and among others the EU Military Staff and the European Defense Agency. In 2017, several institutions were established to modernize and integrate several hundred dispersed European defense companies and equip them with competitive technologies. The European Defense Fund and the Coordinated Annual Review on Defense (CARD) play an important role in this area. In 2022, integration processes in the field of defense were accelerated due to Russia's aggression against Ukraine, as well as after the adoption of a new European Union security strategy called the Strategic Compass. The European Defense Agency has also published the results and conclusions of CARD 2022.

Purpose: The purpose of the publication was to attempt to present housing cooperatives as a competitive entity in relation to other entities forming the „real estate stock”. The resource of housing cooperatives was presented and compared to the resource of other entities operating on the real estate market in Poland. It also shows how housing cooperatives are performing on the real estate market in Poland. Design/methodology/approach: Empirical research on the competitiveness of housing cooperatives in the real estate market was nationwide. The number of dwellings put into use by particular entities operating on the real estate market in Poland has been analysed with a division into voivodships. The standard of buildings put into use has been characterized, and the quality of housing stock management has been analysed. Data concerning the number of dwellings completed has been obtained from the Local Data Bank of the Central Statistical Office and from the Analysis and Monitoring System form the Real Estate Market (AMRON). Findings: The legally and historically established position of the owner of often huge housing resources and the gap between housing cooperatives to function without any assessment of their competitiveness. Legal changes, which include the right to transform a cooperative right into separate ownership of premises, the right to change the property manager from a cooperative to a competitive commercial entity, undoubtedly force housing cooperatives to compete in the housing market in Poland. Originality/value: To date, competition between operators in the property market has not been studied. In this publication, the authors examined the competitiveness of housing cooperatives in relation to other business entities.

Currently, focus on dry ports in the People's Republic of China (PRC) is growing, and therefore, the number of dry ports in the country is actively increasing. Due to the multifunctionality of dry ports, they meet the modern requirements of China's transport policy, which prioritizes improving the quality of providing transportation services by providing general access to value-added and high-quality services. The purpose of the PRC's transport system is also to facilitate the movement of freight flows within the State's territory, due to a faster modal shift, increased accessibility of transport, development of auxiliary functions, and construction of integrated transport hubs. Dry ports deal with the mentioned tasks; however, with the increase in the number of dry ports in the PRC, the issue of optimizing the interaction between dry ports has become urgent. The purpose of this research is to scientifically substantiate the need for strengthening technological cooperation between dry ports. The problem of determining the optimal structure of the system of interaction of dry ports was solved using the method of discreteevent simulation and the anyLogistix software tool. The results of assessment of the economic efficiency of the interaction between dry ports are presented. The results of experiments with a model of China’s dry port system showed the possibility of increasing the total profit of participants of the supply chain by 2.3 times and their profitability by 2.6 times, reducing the cost of container transportation by 1.3 times, and fully meeting the demand for transportation. It has been proven that the cooperation of dry ports in supply chains provides enhanced opportunities for processing cargo flows, as a result of the redirection of cargo consignments from overloaded dry ports to dry ports with reserves ith processing capacity. A methodology for optimizing the structure of the system of interaction of dry ports is presented. The methodology is proposed for use as a tool for strategic and current planning of supply chains.

Purpose: The article is a theoretical one and aims to presents potential threats for academics and science development in the context of corporate university model which is functioning in other countries. Design/methodology/approach: Critical literature review, especially concentrating on studies which results refer to the experiences of academics from countries where corporate university model has been implemented. Findings: Dominating organizational culture of competition and continuous audits based on citations (IF) evidently contribute to the number of publications and their citations. Unfortunately, at the same time there is also a growing amount of publications, including JCR journals, which do not add any value the science. “Scientists” who “produce” these papers are entrepreneurs able to use the Questionable Research Practices. Research limitations/implications: There is a need to develop and publicize this problem because it is a real threat to science. It is necessary to pay greater attention to ethics in the scientist's conduct and to introduce mechanisms to discourage potential "entrepreneurs". Originality/value: The article highlights a new research and social problem, which is a fraud in science.

The practical implementation of hazard analysis and critical control point (HACCP) and in particular the definition of the critical control points (CCPs) in the food industry is usually a complex structured task. This is particularly the case of food enterprise, where quality/safety manager ability, knowledge of the production processes and ‘‘sensitiveness’’ is usually the discriminate for the proper identification and prioritization of risks. The same applies for the definition of causes which may lead to food safety hazards. This paper addresses the issues of how quality/safety managers can objectively and automatically implement the HACCP principles of hazard analysis in the application of HACCP, which is the identification of risk priorities and of the related CCPs. The proposed methodology combines decision tree analysis approach for the analytical decomposition of the relevant steps in the manufacturing process of ice cream.

It is demonstrated that (1) transport enterprises can operate on the market with a profit of zero and (2) they can finance their investments without profit. The rigid conditions of pure competition are not necessary. It is enough to adjust the different situations of incomplete competition by setting equal and homogeneous rules for accounting, founding and running enterprises well as financing. A special rule is to have no foreign trade. But these conditions are not stringent. There are many non-profit-enterprises in Austria and a lot of other countries which are operating without these conditions. The result is a new maxim for (transport) economics: Application of the principle of covering the costs and optimization of quality in spite of profit maximization! THE postulate to consider the quality in transport theory and policy has the same long tradition as the postulate to applicate the principle of covering the costs. The joint application will bring more benefit for realizing welfare and an equal distribution of income and property.

In the case of competing industries, proper assessment of needs and opportunities supported by market analysis and forecast allows adopting strategies for dealing with competition. Coopetition of services is one of the possibilities for the development of entities. The article indicates the reasons for competition cooperation. This cooperation may result from the expectations to increase the scale of impact, reduce operating costs or offer an extended package of services. This causes the need to study customer needs and identify market trends, and consequently build scenarios that are answer to them and allow to adapt to market changes.

The peculiarity of the transit freight transportation by rail in international traffic is the fact that while performing transportation, the railway administrations are in competition among themselves. At the same time, the routes of cargo traffic volumes significantly depend on the conditions of transportation by railways of individual states. The mathematical model for the distribution of transit freight traffic volumes on the railway network, based on the methods of graph theory and game theory, was proposed in this article. The developed model enables the evaluation of the possibilities of attracting transit freight traffic volumes by individual railway administrations by changing the tariff value and transportation conditions.

The purpose of the publication is to determine the level of consumer awareness regarding the knowledge of quality marks and food safety awareness in the aspect of purchasing decisions. The research covered a group of 51 respondents who were residents of the Silesian Voivodship. On the basis of literature research and analysis in the field of food quality and safety, the following hypothesis was formulated: By using generally known management methods, we can determine the degree of consumer awareness in terms of quality labels and food safety in the aspect of purchasing decisions. The research was conducted on a quarterly basis in 2018 based on a questionnaire (CAWI - Computer Assisted Web Interview). The results of research and their analysis have shown that consumer awareness regarding the awareness of quality marks increases, however, there is still a great need to build consumer awareness regarding the existence of quality marks and information that they provide to the consumer in terms of both quality and food safety. Research has shown that consumers are aware of the quality marks existence, but their knowledge about familiarity is still too small. It was shown that consumers, when making purchasing decisions, pay attention to product quality, price, quality certificate and ecological certificate. The factor that determines the safety of the product according to consumers turns out to be its composition. Consumers showed in research that they will not buy a product that has palm oil, sulfur dioxide, glucose-fructose syrup and aspartame.

Artykuł opisuje tło instytucjonalne kryzysu kolei pasażerskiej w Polsce w okresie 1990–2015. Wskazuje etapy przekształceń podmiotów i procedury kształtujące obszar kolejowych przewozów regionalnych. Zwrócono zarazem uwagę na zależności pomiędzy modelami zamawiania i finansowania usług o charakterze służby publicznej a ich jakością i efektywnością. Analiza oparta jest na ocenie zmian o charakterze formalnoprawnym oraz statystyk ilustrujących udziały rynkowe przewoźników. Wnioski wskazują natomiast na zalety modelu opartego na silnym i kompetentnym ośrodku decyzyjnym oraz konkurencyjnym trybie wyboru operatora usług publicznych, i tym samym mogą stać się elementem dyskusji o dalszych przekształceniach sektora kolejowego w Polsce.

The article describes the institutional background of the passenger rail crisis in Poland between 1990 and 2015. It indicates the stages of transformation of entities and procedures. It also draws attention to dependencies, between the models for ordering and financing PSO and their quality and effectiveness. The analysis is based on the assessment of formal and legal changes and statistics illustrating the market share of carriers. The conclusions, on the other hand, indicate the advantages of a model based on a strong and competent decision-making center and a competitive mode of selecting rail operator, and thus constitute a practical recommendation as to further transformations of the railway sector in Poland.

We studied species composition and seasonal co-existence of coprophagous Scarabaeoidea from two study sites in karst meadows in sub-Mediterranean Slovenia. Each site consisted of three habitat patches with different impact of grazing (S1, the active part of the pasture; S2, the overgrown part of the pasture, mainly spiny shrubs; S3, a meadow with some overgrown patches of shrubs outside the fenced pasture). Four pitfall trapping events per month were conducted from March until November to test for temporal, spatial and habitat-related segregation of species. Primary results show a high level of temporal segregation of species within and between the guilds (Aphodiidae – dwellers, Geotrupidae – tunnelers, Scarabaeidae – tunnelers, Scarabaeidae – rollers). Temporal segregation of monthly samples was evident between Aphodiidae – dwellers (most active at the beginning and end of the season, with a month of complete inactivity during hot summer) and Scarabaeidae – tunnelers (present all the time, but with least species and specimens at the beginning and end of season). Intra-guild competition was most prominent for Aphodiidae – dwellers and Geotrupidae – tunnelers, where species show high rate of temporal avoidance to minimize interspecies competition for the same food source. Finally, geographical (site-related) and habitat-related (S1, S2, S3) differences were found in species composition, species richness and abundance, however for the latter two parameters only at habitat level (more species at S1, but higher abundances at S2 and S3). The results imply that the pronounced temporal and spatial segregation facilitate higher biodiversity in space and time, and allow more species to co-exist at the same sites over time.

According to basic ecological principle, species that share the same niche do not occupy the same environment for a long time, and sympatry of two or more such species provides an interesting field for the analysis of their trophic niche differentiation. To examine the potential differences in the dimensions of the trophic niche we studied the diet of three sympatric avian predators that prey on colonial Microtus rodents. The study area in central Poland is located in an agricultural landscape, composed of crop fields, as well as meadows and pastures located within a small river valley. The pellets of long-eared owl (Asio otus), barn owl (Tyto alba) and kestrel (Falco tinnunculus) were collected from the 750 m2 study site including church building and its surrounding in the spring of 2016 and 2017. The analysis of pellets provided data on a total of 4128 vertebrate prey individuals (1914 from barn owl, 1749 from long-eared owl, and 465 from kestrel). The most important prey group of all three predators were small mammals (90%, 14 species) and the most frequently preyed species was Microtus arvalis (making up 72% of vertebrate prey of long-eared owl, 59% of kestrel and 53% of barn owl). Despite the general similarity in the diet composition, there were differences in the contribution of several prey species (e.g. Soricomorpha, M. arvalis, Mus musculus, Rattus norvegicus, and Apodemus spp.) and the diversity of the diet between the predators. We conclude that the trophic niches of the studied sympatric species differ in several dimensions, including diel activity, prey size and taxon-specific feeding preferences.

A situation in which appears at the same time a competition and cooperation between the subjects is defined as a coopetition. First of all it is considered at the mezo level – between the companies, but it can be analysed at the micro level – inside the organization. In the second case, it concerns shaping the relations among the employers which compete one with another and at the same time they cooperate. Among the organizations where the coopetion can be analysed we distinguish two types - for profit and non profit. A difference of the functioning of the for profit and non profit organizations can be seen among other things in the differences that refer to the shape of the coopetition. In the article the characteristic of a intraorganizational coopetition in the for profit and non profit subjects was presented. The base to formulate the conclusions was formed by the investigations made in which, to collect the data there were used the semistructure interviews with six sample selected organizations – three for profit and three non profit.

Sytuacja, w której jednocześnie występuje konkurencja i współdziałanie między podmiotami określana jest mianem koopetycji. Rozpatrywana jest ona przede wszystkim na poziomie mezo – między przedsiębiorstwami, ale może być także analizowana na poziomie mikro - wewnątrz organizacji. W drugim przypadku, dotyczy kształtowania się stosunków między funkcjonującymi pracownikami, którzy rywalizują ze sobą, a jednocześnie podejmują współpracę. Wśród organizacji, w których można analizować koopetycję, wyróżniamy dwa typy – działające dla zysku oraz realizujące cele społeczne. Odmienność funkcjonowania organizacji for profit i non profit może uwidaczniać się m.in. w różnicach dotyczących kształtowania się koopetycji. W artykule dokonano omówienia charakteru koopetycji wewnątrzorganizacyjnej w podmiotach for-profit i non-profit. Podstawę do sformułowania wniosków stanowiły przeprowadzone badania, w których do zebrania danych posłużono się wywiadami częściowo ustrukturyzowanymi z sześcioma celowo dobranymi organizacjami – trzema for-profit i trzema non-profit.
