Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Поняття “життєвість” в інтродукції рослин як відображення стійкості та енергетичного стану організмів
No full textThe notion in plant introduction have been examined. The criteria of vitality are analysed on the different stages of hierarchy. Numerous examples of vital progresses in plants cultured are cited. The mechanisms of plant hardiness and the role of energetic index in evaluation of its functional condition are discussed
Алгоритми теорії схожості в інтродукції та селекції рослин
No full textNecessity to form the backgrounds for similarity theory in biological sciences is discussed. A perspective of its algorithm usage in plant introduction and breeding is shown. Some elements of this theory, their advantage, shortage and ability of modification for increasing an effect of investigation are examined
Фізіолого-біохімічні і генетичні передумови інтродукції рослин
No full textPhysiological-and-biochemical and genetic methods of estimation of plant ability in introduction are considered. The attention is directed to the importance of combined work of botanists, biochemists, physiologists and breeders in the field of prognosis of introduction effectiveness
Основні поняття і терміни інтродукції рослин
No full textThe paper gives the insight into the role of terminology in science. A necessity of accurate definition and revision of the main ideas of introduction and acclimatization of plants is emphasized. The author’s point of view on the definition of the terms “introduction”, “adaptation”, "acclimatization”, “naturalization”, “reintroduction”, “repatriation” and associated ideas are represented. The necessity of their broad discussion is noted
Критерії стійкості в інтродукції рослин
No full textAt different levels of organization the various criteria of stability of plants are considered. The specific and not specific (integrated) criteria of estimate of a status organisms are analyzed, the opportunity of their use in introduction of plants is shown
Математичне моделювання як метод інтродукційного прогнозування
No full textPrinciples and methods of mathematical model of plant introduction are discussed. Modelling is considered from positions of system analysis. The model of dependence of plant resistance on the effects of no less than two factors of environment is offered. It is based on the theory of optimization of researches and is the system of equations of regression. This model allows not only plant resistance characterization in new conditions, but also carry out the selection of environment factors combination, at which plants resistance will be maximal
Історичні закономірності розвитку інтродукції рослин
No full textIn the historical aspect, the main stages and patterns of the development of plant introductions are considered. Views of T. Kuhn, V.D. Fedorov, F. Capra, V.N. Strakhov and B.M. Mirkin on the features of the formation of scientific theories and the paradigm shift as a natural phenomenon that determines the increase in the scientific level of research. Considering the introduction of plants from these positions, it can be argued that this science is cur rently experiencing another paradigm shift. The binary direction in natural science and in the introduction of plants in particular, is regarded as a brake in its development. This is opposed to the systemic approach and the trinitarian methodology as an alternative to the binary one. Trinitarian worldview is not opposed to the binary, but develops and supplements it, restoring ideas about the integrity that was lost in the analytic era. Based on this methodology, we formulated the information-energy theoryof plant introduction and its importance
Значення інформаційно-енергетичної теорії і основні перспективи її використання в інтродукції рослин
