Undoubtedly, one of the most powerful applications that allow symbolic computations is Wolfram Mathematica. However, it turns out that sometimes Mathematica does not give the desired result despite its continuous improvement. Moreover, these gaps are not filled by many authors of books and tutorials. For example, our attempts to obtain a compact symbolic description of the roots of polynomials or coefficients of a polynomial with known roots using Mathematica have often failed and they still fail. Years of our work with theory, computations, and different kinds of applications in the area of polynomials indicate that an application ‘offering’ the user alternative methods of solving a given problem would be extremely useful. Such an application would be valuable not only for people who look for solutions to very specific problems but also for people who need different descriptions of solutions to known problems than those given by classical methods. Therefore, we propose the development of an application that would be not only a program doing calculations but also containing an interactive database about polynomials. In this paper, we present examples of methods and information which could be included in the described project.

The objectives of this research are to know and to analyze about the effect of Continuous Improvement on the performance of employees at PT. Rentang Buana Niagamakmur (PT.RBN) Tasikmalaya. Research method which applied in this research is survey research method, while data collecting technique is done by through questionaire. Sampling technique applies sample is accidental sampling technique and the size sample is 55 respondents. Data analysis techniques used in the study is simple regression technique, analysis of the coefficient of determination  and t test. The results showed that the Continuous Improvement  including both criteria, including employee performance criteria, as well as Continuous Improvement  has a positive influence on employee performance of 76,4% in PT . Rentang Buana Niagamakmur (PT.RBN) Tasikmalaya.

This study considers the influence of structural change on aggregate labour productivity growth of the Russian economy. The term "structural change" refers to labour reallocation both between industries and between formal and informal segments within an industry. Using Russia KLEMS and official Rosstat data we decompose aggregate labour productivity growth into intra-industry (within) and between industry effects with four alternative methods of the shift-share analysis. All methods provide consistent results and demonstrate that total labour reallocation has been growth enhancing though the informality expansion has had a negative effect. As our study suggests, it is caused by growing variation in productivity levels across industries.

Continuous Improvement (CI) jest dobrze znaną koncepcją w literaturze i praktyce zarządzania, i jest uważana za niezbędną w dzisiejszym środowisku biznesowym. Artykuł zawiera omówienie wyników badania przeprowadzonego z zastosowaniem modelu dojrzałości Continuous Improvement w aspekcie oceny liniowości procesu wdrażania kluczowych zachowań CI. W badaniach zastosowano pięciostopniowy model dojrzałości CI, w celu weryfikacji jego przydatności w ocenie poziomu realizacji kluczowych zachowań tej koncepcji w przedsiębiorstwie produkcyjnym, jak i w celu zbadania charakteru przebiegu tego procesu. W pierwszej części artykułu zaprezentowano wnioski wynikające z analizy literatury dotyczącej modelu dojrzałości, a następnie przedstawiono wyniki badań empirycznych zrealizowanych w dużym przedsiębiorstwie produkcyjnym. Na tej podstawie przeprowadzono dyskusję dotyczącą odpowiedzi na postawione pytania badawcze. Potwierdzono przydatność modelu w ocenie poziomu dojrzałości, jak i zwrócono uwagę na nieliniowy charakter procesu rozwoju kluczowych zachowań CI wdrażanych w przedsiębiorstwie. Podczas gdy model sugeruje, że rozwój dojrzałości CI powinien być procesem liniowym, wyniki badania wskazują, że istnieją realne alternatywy dla przedsiębiorstw, aby rozwijać zdolność do ciągłego doskonalenia.
