Small and medium-sized enterprizes : opportunities and challenges
Small and medium-sized enterprises play a major role in national economy. However, their lifetime is limited by the micro-economic climate. This paper discusses whether credit exposure has a major impact on the rate of bankruptcy and this hypothesis is verified by means of statistical methods, based on official statistical data and selected published studies and researches. The hypothesis was not fully confirmed in our investigation. The output of the paper was an evaluation of the dependency of bankruptcy of SMEs on their credit exposure and the presentation of other factors that might have an impact of SMEs, making them either successful or going to bankruptcy.peer-reviewe
Stabilization factors of family enterprises in the context of macroeconomic performance
The article describes performance and stabilization factors in the context of macroeconomic performance of small and medium-sized enterprises (SMEs), which comprise also family businesses (SMEs) in the Czech Republic. We consider the number of SMEs active entrepreneurial subjects, the number of SMEs employees, the accounting value added of SMEs and the wage costs of SMEs the performance and stabilization factors. As a representative of macroeconomic performance the authors chose GDP. The stability and performance of SMEs are examined through statistical methods: the Pearson correlation coefficient and the average growth factor. The statistical methods are applied to the data time series between 2002 and 2016. The stability and performance factors are mutually measured and evaluated.peer-reviewe
Development of a consensus classification of physiotherapy interventions in paediatric neurorehabilitation
Background and Aims Physiotherapy within paediatric neurorehabilitation is a complex process whereby the relationship between treatments delivered and resultant severity-adjusted patient outcomes have been difficult to demonstrate. An essential prerequisite for analysing physiotherapy input at the point of its delivery to the patient is to have clear descriptions and categories of physiotherapy interventions. Recent work in this area has focussed on grouping treatments based on their common essential ingredients. The aim of this work is to develop an expert-lead consensus classification of physiotherapy interventions used in paediatric neurorehabilitation, categorised according to their essential ingredients, actions and mediators. Method Comprehensive literature searches of five electronic databases (MEDLINE, EMBASE, AMED, CINAHL and PsychINFO) together with supplementary hand searching identified 4,194 studies which were separated into 34 different interventions following cross-referencing with other sources. These were then divided into eight distinct categories according to their essential treatment ingredients. A panel of 13 expert physiotherapists specialising in the field of paediatric neurorehabilitation were consulted in two rounds of an online modifiedDelphi survey (a method commonly used to glean expert consensus). Results In modified-Delphi survey rounds 1 and 2 respectively, eight (62%) and nine (69%) of the experts responded. Utilising a threshold of ≥75% agreement set a priori to represent expert consensus, there was agreement that the eight categories are comprehensive (complete) and unambiguous (easily understood). What remains less clear is the extent to which these categories are independent of one another. Discussion This categorisation of physiotherapy interventions within paediatric neurorehabilitation is the first of its kind to group treatments according to their essential treatment ingredients. Such work adds the potential for gleaning greater understanding regarding how physiotherapy leads to improved patient outcomes within paediatric neurorehabilitation. Further work is required in this area to better understand the extent to which different categories are truly independent or where similarities exist between them

Using time-frequency analysis to determine time-resolved detonation velocity with microwave interferometry
Two time-frequency analysis methods based on the short-time Fourier transform (STFT) and continuous wavelet transform (CWT) were used to determine time-resolved detonation velocities with microwave interferometry (MI). The results were directly compared to well-established analysis techniques consisting of a peak-picking routine as well as a phase unwrapping method (i.e., quadrature analysis). The comparison is conducted on experimental data consisting of transient detonation phenomena observed in triaminotrinitrobenzene and ammonium nitrate-urea explosives, representing high and low quality MI signals, respectively. Time-frequency analysis proved much more capable of extracting useful and highly resolved velocity information from low quality signals than the phase unwrapping and peak-picking methods. Additionally, control of the time-frequency methods is mainly constrained to a single parameter which allows for a highly unbiased analysis method to extract velocity information. In contrast, the phase unwrapping technique introduces user based variability while the peak-picking technique does not achieve a highly resolved velocity result. Both STFT and CWT methods are proposed as improved additions to the analysis methods applied to MI detonation experiments, and may be useful in similar applications
Virtualización del Módulo de Ventas Multicamal utilizando el estándar de Arquitectura Websphere Message Broker para la integración de Aplicaciones en el Centro de Investigación Tecnológica BCP
Este proyecto de investigación se ha desarrollado con la finalidad de integrar las
aplicaciones del módulo de motor de ventas multicanal utilizando la arquitectura ESB
(Enterprise Service Bus) utilizando WebSphere Message Broker. La utilización de esta
arquitectura es importante debido a que permite, a través de un único canal, poder ejecutar
las acciones pertinentes con la finalidad de que las aplicaciones consumidoras de servicios
obtengan la data necesaria y en el formato adecuado por parte de las aplicaciones
proveedoras; además, al utilizar WebSphere Message Broker, se permite la reutilización
de servicios toda vez que es este medio el que realiza las transformaciones necesarias para
que las aplicaciones consumidoras puedan utilizar la data expuesta por parte de las
aplicaciones proveedoras.
Se ha implementado este proyecto utilizando herramientas diseñadas por el banco como
MFX o Mensajería Financiera Badasa en XML, el cual es un estándar desarrollado por el
BCP, principalmente porque es aplicable a la realidad del banco, es abierto a ser extendido
y simple pero bien estructurado.
Estos servicios, que han sido implementados utilizando WebSphere Message Broker, son
denominados servicios virtualizados debido a que son servicios generados a partir de otros
servicios de negocio y nunca desde el aplicativo Core. Además para la implementación de
estos servicios virtualizados se ha hecho uso de SOA o Arquitectura orientada a servicios
por sus siglas en inglés, toda vez que SOA proporciona técnicas útiles y necesarias para
construir servicios utilizando Web Sphere Message Broke
