“…1. Our assumption is that each inter-stage link has the capacity equal to f AUs (allocation units, e.g., links, channels, basic bandwidth units [52]). The output links of the switching network are grouped into link groups that create the so-called output directions towards the neighbouring nodes of the network.…”

This article proposes a new analytical method of determining occupancy distribution and blocking probability in multiservice switching networks with admission control mechanisms and resource management mechanisms. The proposed method is a universal one, which allows for determining blocking probability using the same model, regardless of the type of admission control mechanisms and resource management mechanisms. The versatility of the method is demonstrated in the article for two selected mechanisms, i.e. a threshold mechanism and a resource reservation mechanisms. The switching networks under consideration are offered multiservice traffic streams, generated by the so-called multiservice sources, according to Erlang, Engset and Pascal distributions. The proposed method is based on a generalised way of determining traffic characteristics for inter-stage links of switching networks with resource and call management mechanisms. Particular attention is given to determining the influence of the introduced mechanisms in outgoing links of the switching network on the traffic properties of inter-stage links of the network. The results of analytical calculations are then compared with the results obtained in digital simulation for a number of selected switching networks.

“…The conditional P(T>τ│T>t) and unconditional P(T>τ) probabilities are identical, which means that knowledge about the past does not have any influence over the variable characterized by exponential distribution [Stasiak et al 2010]. In consequence, changes characterized by exponential distribution cannot be used in the analysis aiming to predict future events.…”

English and in an open mode. REF is a quarterly journal, with the second issue containing six research articles. Two of the articles focus on the social and socio-economic aspects of development and business, one article looks at small family businesses and their path to growth; another paper dwells on the topic of sustainable agriculture, with two last research articles depicting financial subject matters such as currency rates and asset pricing. Let us bring you closer to the outcomes of the works presented in volume 2.The article entitled Proposal of alternative typology of social economy by A. Waligóra presents an alternative proposal of division in social economy, focusing on the social functions of its entities -social enterprises. The proposed solution serves to fulfil the dominant discourse of the social economy in new ways of thinking about the reasons and motivations connected with creating social enterprises. The article's conclusions are considered in the light of Piotr Sztompka's social capital theory and the theory of social cost.The article entitled Investigation of the social factors of development of society in the territories with transforming environment by O. Kvilinskyi, A. Mieshkov and I. Bondaryeva aims at identifying the main social factors that affect the vital activity of society at the present stage of development of territories which have unstable socio-economic and political environment. The authors have developed a methodology of an expert assessment of the importance of the factors of forming the system of vital social activity. A set of recommendations for the coordinated impact on the economic and social processes in the conditions of transforming the market system have been proposed as a result of the research.The article entitled Family Firms as a potential source of growth for the Warsaw Stock Exchange by S. Filipczak discusses the possibility that family firms will step into the state's shoes and become a more meaningful source of new issuers for the Warsaw Stock Exchange. The paper identifies the reasons for a possible increase in family firms listings on the WSE as well as key elements for that to happen. The author notes that an increasing number of family firms are big enough to meet the WSE requirements, and thus a wave of succession in family enterprises is expected in the coming years.The article entitled Theoretical Framework for Stock Pricing Process based on Micro-Economic Decision Model by V. Kanagov introduces a theoretical framework for a new model which aims at avoiding the problems of CAPM, the most common model for asset pricing, and keeping its advantages, therefore allowing universality of asset pricing. It is based on the micro-economic decision model, involving an expected value and dividing a stock price to objective and subjective prices. As a result, rational based individuals, just like individuals with non-rational factors, may use the model to calculate a future price stock in exactly the same way.

“…Due to this latter point, in order to extend broadband networks to rural and remote areas to 100% of the population, it is not a business for telecommunication operators [10]. The challenge of providing broadband services in rural and remote areas has gained increased attention in recent years.…”

Abstract. It is recognized that there is a disparity between broadband availability in urban and rural areas. The pre-existing telecommunications infrastructure is generally poor and unevenly distributed in favor of urban centers. In most rural areas, low population density and high deployment costs discourage private investments, creating a negative feedback of limited capacity, high prices, and low service demand. Building telecommunications networks in rural areas is costly. Further, in many cases, there is not a good commercial business case for rural deployments. Whereas established and competitive service providers already offer solutions for urban and suburban areas, there is little or no commitment to connect areas that include smaller towns and rural villages. The deployment of access network broadband services on low-competition areas is characterized by low subscriber densities, longer loop lengths, lower duct availability, and consequently higher infrastructure cost compared to high-competition areas.
