In search of a negotiation paradigm

100%
To date, the interest in negotiations has concerned, first of all, a sphere of practical activity. The notion of “negotiations” also means a science. This article attempts to define the stage of its development. With this aim in view, Kuhn’s concept of a paradigm has been referred to, which is regarded as a central category used in the evaluation of the development of science. The article involves a critical analysis of previous attempts to define a paradigm of negotiations, proving that science of negotiations is still in its pre-paradigmatic phase. It discusses dilemmas and challenges which it faces at the current stage of its development.
The purpose of this article is to assess the changes in proclaimed paradigms regarding development of the agricultural sector in the EU with particular focus on barriers to these changes. The theoretical part highlights the types of changes in the public policies, the main models of paradigm developments and the impact of institutional factors, including structures of policy networks on their changes. In the next part the CAP proclaimed paradigms are shown against the effects of the current policy. At the same time, these elements of policy network structure which contribute to the replication of the existing patterns of development are indicated. The summary contains refl ections on the possibility of institutional change in the development of the CAP. It was found that only further reduction of the agricultural budget after 2020 can become a source of conflict between the actors (stakeholders) around available resources and may change the balance of power in the decision-making process in the CAP.

Subject and purpose of work: This work is devoted to presenting the development of the systemic paradigm in marketing science. Its purpose is to discuss the genesis and early stages of the development of systemic paradigm that forms the basis of one of its mainstream marketing theories, known as macromarketing. Materials and methods: The article was created on the basis of the review and synthesis of the previous studies devoted to the issue of systemic approach to marketing and marketing systems. The historical analysis method, combined with the synthesis of earlier research achievements, was employed. Results: The article fills a gap in the area of identifying alternative paradigms of marketing science. It demonstrates how the systemic approach proposed by the forerunners of marketing was developed into a concept which is now the foundation of one of contemporary marketing sub-disciplines - macromarketing. Conclusions: The main conclusion that follows from the conducted analysis is the observation that systemic paradigm is deeply ingrained in the tradition of marketing thought, creating a prominent direction of reflection which is more concerned with the environmental and social role of marketing than with marketing as a management function.
The paper reviews the concept of public goods, indicating its various dimensions. The fundamental objective of the paper is conceptualizing public goods and answering a question whether a public goods delivered by agricultural land is valorized in land prices. The aim of the study was also to identify the mechanism that makes intrinsic land utility transformed into productivity in monetary units. A conducted research consists in deriving a land rent capitalized in land prices and estimating its share in land value in comparison with the share of lease fees in the different regions of Poland in years 2000–2009. In the authors opinion since accession of Poland to the UE a market has valorized intrinsic utilities of land, whereas the new role of capital and labour is distribution of those utilities in favour of consumers. Given the fact that there is a lack of Polish scientifi c studies on agricultural areas as a provider of public goods fi ndings of foreign scientists were also used in the research. Since the beginning of human civilization, the land has been creating certain utilities which satisfy human needs. When the dangerous side effects of industrial agriculture have occurred intrinsic land utilities are being discovered anew. They have a nature of public goods and constitute a hard core of the sustainable agriculture paradigm. Despite irreversible accumulation of capital in the anthropogenic environment many new utilities of the land come into existence without additional capital and labour inputs. Since they are public goods, they are paid from taxes in great measure. This way an intrinsic land utility takes a form of a paid product and can be called “intrinsic productivity” of land.
Contemporary sociology of culture is on the verge of change of its paradigm. From a science the aim of which is to measure the consumption of culture or to interpret culture it is to be transformed into a research discipline studying the way in which the culture is experienced. Thus, the statistical or hermeneutic rules will have to be replaced by the assumptions which look for the corporeality of the human bodies as a source and essence of the culture. “Physical”, not “mental” meanings would be treated as the objects of sociological and humanistic research. Thanks to that the neo-naturalism may become the mainstream of the future in these sciences.
The neurocognitive consequences of correct or incorrect spatial prediction in a sequential S1-S2 paradigm were assessed. Sequential dependence on previous trial outcome (valid or invalid) was assessed by late Event-Related Potentials (ERPs) and behavioural responses. Two different experiments were performed, situating the target in the vertical (Experiment 1) or in the horizontal (Experiment 2) meridian. RTs and late positivities (P3a and P3b) were recorded. ERPs showed that posterior positivity (probably a P3b) was greater in invalid-valid trials than in valid-valid trials but lower than in valid- invalid trials. However, at the frontal electrodes, late positivity (probably a P3a) only appeared in valid-invalid trials, indicating that invalid trials are analyzed as novel-like stimuli. The P3b results suggest trial-by-trial learning of the predictive value of the cue, which needs to be updated as indicated by the pattern of P3b amplitudes: valid-invalid > invalid-valid > valid-valid.
In the past 30 years, Daphnia has become a model organism in aquatic ecology. I review the changing concepts and paradigms in plankton ecology as reflected in the work on Daphnia. The availability of radiotracers favoured a new physiological approach that resulted in better energetic models and more reliable estimates of filtering rates. This led to deeper insights into the role of herbivore grazing on phytoplankton and microbial communities, and nutrient recycling. It provided a conceptual basis for general hypotheses on predictable seasonal successions (e.g. the PEG model). On the other hand, increasing knowledge about selective predation on zooplankton triggered population dynamic models and gave explanations for changing community structures. The Size-Efficiency-Hypothesis generated a framework for studies on trade-offs between competitive ability and susceptibility to predation. Daphnia was now in the centre of interaction-based concepts, being predator and prey at the same time. It was the backbone of practical applications of the theory in food-web manipulations. When ultimate factors came into the focus, Daphnia played an important role in explaining striking phenomena like diel vertical migration and cyclomorphosis. Its central position in food-webs, the unique propagation mode, easy cultivation and accessibility by molecular genetic methods made it a favourite object for studies in evolutionary ecology, concerning local ad a ptation, evolution of defences and life histories, induced phenotypic change, and genetic diversity. The large advantage of Daphnia over other biological model organisms is that its importance in pelagic freshwater systems is undoubtedly known. Hence there is a direct way of applying the results to ecological systems.
