Reconciling the interests of the economic diversification participants in a single-industry town

Рассматриваются проблемы согласования интересов участников процесса диверсификации экономики моногорода в процессе управления развитием моногорода на основе реализации стратегии диверсификации. Целью исследования является разработка инструментов гармонизации интересов участников процесса диверсификации экономики моногорода на основе разработки модели полного согласования интересов и сопоставления ее с моделью отдельно взятого моногорода. Методы исследования: системный подход, анализ и синтез, построение множеств согласования интересов с применением диаграммы Эйлера-Венна, методы комбинаторики, построение экономических показателей и рядов динамики, графический метод представления результатов и построения иерархии согласования интересов. Результаты исследования. Представлена модель полного согласования интересов различных групп лиц, в которой отражены сферы возможного пересечения интересов, а также иерархия числа согласуемых интересов. Предложены основные группы участников процесса диверсификации моногорода, а также разграничено понятие участника и роли (функции) участника в данном процессе. Обосновано и определено число множеств в зависимости от числа участников, чьи интересы одновременно согласуются, на примере моногорода Калтан Кемеровской области. На основе предложенной модели построена модель согласования интересов на примере моногорода Калтана. Полученная модель имеет трапециевидную форму, что свидетельствует о достаточно небольшом числе общих согласуемых интересов. Автор приходит к выводу, что в моногороде сформирован треугольник интересов «администрация города - малый бизнес в роли инвестора - вуз», представляющий основу в иерархии согласования интересов моногорода Калтан. Центральное положение при согласовании интересов с прочими участниками занимает исключительно администрация города. На основе данных выводов внесены предложения по направлениям дальнейшего согласования интересов на примере рассматриваемого моногорода.The article explores the problems of reconciling the interests of single-industry towns, a need that arises from the entire process of industry development management through a diversification strategy. The aim of this study is to develop tools to harmonize the interests of the single-industry towns, based on a model of full harmonization with the model of an individual single-industry town. Methods of the research: system approach, analysis and synthesis, building a set of harmonized interests with the application of the Eulerian-Venn diagram, combinatorics methods, construction of economic indicators and series of dynamics, graphical method of presentation of results and building the hierarchy of interests. Results of the study. The paper introduces the model for fully reconciling the interests of different groups of persons, reflecting the areas of possible intersecting interests and the hierarchy of the number of interests involved. The article proposes the main groups of participants in the diversification process and the differentially concept of participant and the role (function) of the participant in the diversification process. The author justifies and estimates the number of sets depending on the number of participants whose interests are concurrently reconciled in Kaltan case study. The proposed model is used for Kaltan, Kemerovo region case study. The result ing model is of a trapezoidal form, which indicates that there are quite a few common consenting interests. The author concludes that a triangle of interests «city administration - small business as investor - university» is formed. This triangle represents the highest level of harmonization of interests in the hierarchy. The city administration is in central position in reconciling interests with other participants. By the example of the considered single-industry town and based on these findings the suggestion on further harmonization of interests was made

Macroscopic Geometrical Modelling of Oil Palm Mesocarp Fibers of Three Varieties of Palm Nut

International audienceThis work is part of a process of characterization of plant fibers. The macroscopic geometric parameter of Oil Palm Mesocarp Fibers (length, diameter) was measured. A mathematical model of the evolution of the cross-section is provided in order to facilitate a digital reconstruction of the geometry of these fibers. In this context, we manually isolated with great care many fibers of several oil palm varieties Dura, Tenera and Pissifera distinguishing for the last two varieties two extraction position. Five different partitions of fibers have been studied. The lengths of these fibers were measured and the transverse dimensions of each of the fibers were taken at five equally spaced discrete and different sections. For each section, we made two measurements at 90 ° in the front plane and the profile view. The mathematical model of the evolution of the profile were determined in each plan and the evolution of the cross section model was described for each of the five partitions on the basic assumption that this cross section is elliptical according to SEM images and flattening rate of the cross section we calculated. Introduction. The use of vegetable fibers as reinforcement in composite materials to replace synthetic fibers is growing rapidly. Many researches are interested in it in order to optimize their physical and mechanical properties [1-5]. Many fibers (sisal, coir, raffia, jute ...) are studied in the literature [6]. The fibers from palm oil tree (EFBF 4 , OPMF 5 , OPTF 6) also have a particular interest [2, 3, 5, 7, 8]. It is clear from the various work that knowing the geometry of the fiber (section and length) is indispensable for the analysis of the results of a physicochemical characterization test (water absorption kinetic of fiber) [9], mechanical characterization (determination of Young's modulus of the fiber) [7, 10, 11] and during predictive calculations of composite properties [12, 13] (application of composites homogenization theories). All Authors are unanimous on the versatility of the geometry of the cross section and its non-uniformity along the vegetable fibers. It is shown [14-18] that the mechanical properties of sisal, jute, hemp, bamboo and coconut fiber may be influenced by the dimensions and aspect of their cross-section. Most of the works in the literature consider an approximation of vegetable fibers to a straight beam of constant circular cross section [6, 19] (in this case, the diameter measurement is made on a singular section); on the other hand, consider that the fiber is a straight beam of elliptic section and constant (measuring the major axis and the minor axis of a singular cross section) on which several measurements can be made and the average of these measurements considered as mean cross section of the fiber. Some author [11] propose a method for assessing the cross section of kenaf fibers by image analysis but this study is limited to a single sectio
