In their article, the authors present the essence of sustainable consumption and the level of awareness among Polish consumers. A particular attention is paid to collaborative consumption as one of possible ways of implementation the idea of sustainable consumption. They made an attempt to characterise collaborative consumption and its manifestations in Poles’ behaviours. They paid attention to some aspects of consumers’ behaviours which may be treated as designata of the trend indicating, at the same time, the possible popularisation of those behaviours. Based on an analysis of the carried out quantitative research surveys, the authors defined the sociodemographic profile of consumers being supporters or opponents of collaborative consumption indicating that the issue of belonging to these categories is decided by the basic sociodemographic variables and awareness of the idea of collaborative consumption.
Logistics is mentioned as a tool for decreasing uncertainty in a business. There are necessary changes within integration of logistics performances, increasing of investment into logistics systems, taking big amount of logistics activities within supply chain, active utilization of information and communication technology and last but not least it is necessary to assure increasing demands for individual products. The most important trends of logistics development lies in more lean supply chains and business processes. A suitable tool seems to be value stream (flow) mapping of activities. This paper deals with the methodology of its application.
A diet, individually customized to the needs of sportsmen and sportswomen prepares them better for competition and achievement of better sports results. However, disorders of the gastrointestinal tract and frequently recurrent upper respiratory tract infections pose a common problem observed among athletes of disciplines such as triathlon, cycling and marathon. Diarrhea, splashing in the intestines or gastrointestinal bleeding make it difficult to start and win in the race. Recently researchers have paid special attention to the therapeutic effect of probiotic strains on the human body. Various probiotic strains may have a beneficial effect on elimination of disorders mentioned above among athletes of these disciplines. Still, researchers continue looking for answers to the question how a specific probiotic strain is able to reduce the risk of the gastrointestinal tract and the respiratory system disorders appearing during training or competition. Attention is also drawn to the possible impact of probiotics on the physical capacity athletes and their athletic performance. Probiotic strains properly applied may have a positive influence on the athletes’ bodies, but still randomized controlled trials are required to prove this thesis.
Present economic environment, which is rapidly changing, confronts companies, organisations and institutions with a problem how to protect a long — term competitiveness. A crucial factor is the quality of products and services. It means to bring new methods of management into practice, which is beneficial but these changes must not be autotelic. The main goal is to increase an efficiency, operationality and quality. In terms of modern instruments and methods of management we often meet with ideas like strategic management, TQM (total quality management), knowledge management, human resources management, learnig organisation, business intelligence, balance scorecard.
The main goal of this article is to attract attention of junior scientists interested in evolutionary and ecological parasitology, to some very interesting articles dealing with the methodology of such investigations. The authors review some problems related to terminology used in the studies of host-parasite relationships and then recapitulate the subjects of five articles, in which new indices of the range and characters of hosts specificity are proposed. These are: the article of Caira et al. (2003), Poulin et Mouillot (2003, 2005), Krasnov et al. (2011) and Poulin et al. (2011).
Introduction. A new trend in food production is to use a whey proteins as a food addi- tives. The aim of this research project was to evaluate the impact of increased proportions of whey proteins in sheep milk on the course of its fermentation process. Material and methods. The materials used in the experiments was sheep and cow milk of natural ratio of whey to casein proteins (1:4) and sheep milk in which the ratio of whey to casein proteins amounted to 1:1 and 4:1. The dynamics of the fermentation process and the stability of final products was described on the basis of pH value, titratable acidity, lactose, galactose and lactic acid content. Results. Higher, in relation to natural, ratios of whey to casein proteins (1:1 and 4:1) in sheep milk increased the acidity of the final product after incubation and decreased the degree of fermented lactose. The cooling storage of fermented milks failed to affect changes in pH value, titratable acidity, galactose and lactic acid content of the final products. Conclusion. Changes in ratios of whey to casein proteins result in differences in dynamics of sheep milk fermentation but not influenced on final product's stability.
