Conceptual Foundations of Modelling of Innovative Production Projects

At the moment there is a lack of methodological approaches to formalization of management of innovative projects relating to production systems, as well as to adaptation and practical use of the existing approaches. This article is about one potential approach to the management of innovative projects, which makes the building of innovative process models possible based on objective approach. It outlines the frameworks for the building of innovative project models, and describes the method of transition from conceptual modelling to innovative project management. In this case, the model alone and together with parameters used for evaluation of the project may be unique and depends on the special features of the project, preferences of decision-making person, and production and economic system in which it is to be implemented. Unlike existing approaches, this concept does not place any restrictions on types of models and makes it possible to take into account the specificities of economic and production systems. Principles embodied in the model allow its usage as a basis for simulation model to be used in one of specialized simulation systems, as well as for information system providing information support of decision-making process in production and economic systems both newly developed by the company (enterprise) and designed on the basis of available information systems that interact through the exchange of data. In addition, this article shows that the development of conceptual foundations of innovative project management in the economic and production systems is inseparable from the development of the theory of industrial control systems, and their comprehensive study may be reduced to a set of elements represented as certain algorithms, models and evaluations. Thus, the study of innovative process may be conducted in both directions: from general to particular, and vice versa.

Correlações entre as concentrações de nutrientes, alumínio e sódio nas folhas de "coast cross nº 1" e a análise física e química de um latossol vermelho amarelo: I. Concentrações de nutrientes nas folhas em função das frações granulométricas do solo

Foi realizado um levantamento em 41 áreas de um solo classificado como Latossol Vermelho Amarelo, com amostragens de solo e de folhas da forrageira "Coast Cross nº 1" objetivando o estudo de correlações entre as concentrações de nutrientes, alumínio e sódio nas folhas e as análises físicas do solo. Os autores observaram que a concentração de potássio nas folhas correlaciona-se negativamente com a fração silte do solo. A concentração de cobre nas folhas correlaciona-se negativamente com a fração areia fina e positivamente com argila. Ferro, manganês, zinco, sódio, boro e alumínio não apresentam correlações entre as suas concentrações foliares e os teores de argila no solo.

Correlações entre as concentrações de nutrientes, alumínio e sódio nas folhas de "Coast Cross nº 1" e a análise física e química de um Latossolo vermelho amarelo II: Concentração de nitrogênio e fósforo

Foi realizado um levantamento em 41 pontos de um Latossolo Vermelho Amarelo, com amostragem de solo e folhas da forrageira "Coast Cross Nº 1", objetivando o estudo de correlações entre as concentrações de nutrientes, alumínio e sódio nas folhas e as análises químicas do solo. As folhas foram secas e analisadas para N, P. As amostras de solo foram secas e analisadas pelos seguintes métodos: índices pH (água e CaCl2 0,01 M), matéria orgânica (digestão úmida) , P, K, B, Cu, Fe, Mn, Zn e Na pelo extrator de Mehlich. P através de resina iônica. Ca, Mg e Al pelo KC1 1 N. As frações granulométricas foram dispersas por NaOH 0,1 Ne separadas pelo método da pipeta. Foram observadas correlações entre as concentrações de elementos nas folhas e as determinações no solo. Nitrogênio nas folhas correlacionou-se negativamente com fósforo do solo e positivamente com manganês e enxofre. Fósforo nas folhas correlacionou-se negativamente com cálcio do solo.

Ecological relations between mangrove leaf litter and the spatial distribution of the gastropod Melampus coffeus in a fringe mangrove forest

Leaf litter represents a food source to many organisms that may directly contribute to organic matter decomposition. In addition, the physical presence of these vegetal detritus contributes for the modification of some environmental areas and produce microhabitats that may act as a refuge against predators and desiccation for many animals. The pulmonate gastropod Melampus coffeus (Linnaeus, 1758) (Ellobiidae) is a very common specie in Atlantic Coast mangrove forests and feeds on fallen mangrove leaves. It was hypothesized that the spatial distribution of Melampus coffeus is directly affected by mangrove leaf litter biomass deposition. Thus, this research aimed at evaluating the spatial distribution of these gastropods in relation to the biomass of mangrove leaf litter through a twelve-month period. The study area was established in the middle estuary of Pacoti River, state of Ceará, Brazil where two adjacent zones with different topographic profiles were determined. Samples of Melampus coffeus and leaf litter were collected monthly, throughout a year, from the mangrove ground surface. The results indicated that the presence of twigs in mangrove litter favor the occupation by smaller individuals of M. coffeus, probably because smaller individuals are more susceptible to predator attacks and desiccation than larger ones, and twigs and branches may provide a safe microhabitat.

On games corresponding to sequencing situations with precedence relations

In this paper we study a class of cooperative sequencing games that arise from one-machine sequencing situations in which chain precedence relations are imposed on the jobs. It is shown that these sequencing games are convex.

Personal relations and their effect on behavior in an organizational setting: an experimental study

We study how personal relations affect performance in organizations. In the experimental game we use a manager has to assign different degrees of decision power to two employees. These two employees then have to make distributive decisions which affect themselves and the manager. Our focus is on the effects on managers' assignment of decision power and on employees' distributive decisions of one of the employees and the manager knowing each other personally. Our evidence shows that managers tend to favor employees that they personally know and that these employees tend, more than other employees, to favor the manager in their distributive decisions. However, this behavior does not affect the performance of the employees that do not know the manager. All these effects are independent of whether the employees that know the manager are more or less productive than those who do not know the manager. The results shed light on discrimination and nepotism and its consequences for the performance of family firms and other organizations.
