The main objective of the paper was to determine the significance of particular methods of supporting women's entrepreneurship in Greater Poland. Five groups of such support have been identified: socio-cultural, promotional and informational, financial, institutional, consulting and training. This led to identifying gaps in existing support and to finding the most significant support for entrepreneurial women. The study revealed a discrepancy between the assessment carried out by experts, students and women entrepreneurs. Owners of enterprises’ opinions show that the available forms of support are not as useful as it might seem from the perspective of researchers and potential owners. There are also forms of support that are not used by the female owners.

Diversos autores han establecido la gran importancia que tiene para las empresas el contar con información precisa relativa al costo de cada producto, siendo esto particularmente cierto en el ambiente de la intensa competencia global actual. A pesar de ello, se ha demostrado que los sistemas tradicionales no satisfacen las presentes demandas empresariales por lo que en los últimos años se han propuesto nuevos métodos de costeo los cuales, sin embargo, aún resultan imprecisos. Es por esta situación manifiesta que en este trabajo se presenta una nueva metodología para la determinación del costo de almacenaje de un producto, extrapolable a todos los eslabones de la Cadena de Suministro. A su vez, se propone un nuevo inductor de costo, el índice logístico, el cual contribuye a brindar información más precisa que los métodos tradicionales. Se concluye mostrando un caso de negocio donde se aplica este modelo en una empresa logística española.

En este artículo, se discute el estado del arte en la estimación de la predicción varios pasos adelante para modelos de series temporales no lineales basados en perceptrones multicapa. Se revisan las principales tendencias para la estimación de pronósticos puntuales e intervalos de confianza. En adición, se argumenta sobre los principales problemas abiertos para investigación futura en la predicción de series temporales usando redes neuronales.

It is well known, that the electrical energy storage in the large scale is basically a difficult process. Such a process is connected with energy losses, as most frequently it is the conversion of electrical energy into another form, for example mechanical, and then back to the primal electrical form. Though, the SMES technology offers the energy storage in an unchanged form, which is advantageous primarily in the achieved efficiency. The magnetic resonance imaging (MRI) devices, commonly used in the medical facilities are based on the basis of superconducting magnet. After its rejection from operation, (basically caused only by its „software fustiness“ and not by functional faults), there is a possibility of using such devices for the energy storage purposes. Additionally, such a technology of storage is also ecological. A research project is running at the Faculty of Mining, Ecology, Process Control and Geotechnologies (F BERG), the Department of Business and Management, in the field of using rejected MRI for energy storage purposes.

La variabilidad anatómica presente en los cerebros de pacientes limita la realización de análisis estadísticos acerca de la presencia o ausencia de una patología. En este artículo, presentamos una aproximación para la clasificación de imágenes de Resonancia Magnética (MR) cerebral de sujetos sanos y afectados por una patología. El enfoque se basa en un mapa de saliencia, el cual extrae regiones de cambio relativo en tres diferentes dimensiones: intensidad, orientación y bordes. Las regiones de interés obtenidas se utilizan como patrones para la clasificación de sujetos utilizando máquinas de vectores de soporte. El desempeño de la estrategia propuesta fue evaluado en un conjunto de 198 imágenes de MR extraídas de la base de datos OASIS y divididas en cuatro grupos, reportando una tasa de precisión promedio de y una tasa de error igual (Equal Error Rate) promedio de .

Implementation of professional practice in the course of education process at universities is an important element allowing students to strengthen the knowledge they gained, to acquire relevant skills and to form positive personality traits. The aim of the paper is to evaluate the quality of professional practice in students’ opinion on the basis of the onshore professional practice organized at the Commodity Science and Quality Management specialization at the Faculty of Entrepreneurship and Quality Science at the Gdynia Maritime University. The article presents general rules of organizing practice and it analyses survey questionnaires filled in by students following the realization of the professional practice in the years 2014–2016. Additionally, the results of the students’ perception of the practice are compared with the assessment as granted by the host companies concerning the apprentices’ profiles as future employees of the industry. The conducted analysis allowed to suggest measures to improve the implementation of professional practice at the Commodity Science and Quality Management specialization at the Gdynia Maritime University.
