La valoración de las existencias es uno de los aspectos más problemáticos que tienen las empresas a la hora de presentar sus estados contables. La distinta normativa existente, las variantes que suscita y la complejidad de su interpretación conlleva a valoraciones distintas para las diferentes clases de existencias, afectando a los informes contables y consecuentemente a la toma de decisiones de los responsables empresariales. El acercamiento de las normas contables españolas a las Normas Internacionales de Contabilidad/Normas Internacionales de Información Financiera (NIC/NIIF) puede hacer que aparentemente la diversidad en las valoraciones sea menor. En este artículo queremos presentar la nueva normativa contable española emanada por el Plan General de Contabilidad de 2007 y las semejanzas y diferencias con las NIC/NIIF en todos sus apartados

Tras varias décadas de armonización contable de mínimos mediante la incorporación de las Directivas Comunitarias a cada legislación nacional, la estrategia actual de la Unión Europea de adoptar las normas emitidas por el Consejo Internacional de Normas de Información Financiera (IASB por sus siglas en inglés) y de hacer obligatoria su aplicación a las cuentas consolidadas de las empresas cotizadas para los ejercicios iniciados a partir de 2005, ha traído como consecuencia la necesidad de someter la legislación mercantil y contable en España a una reforma que, en sus principios fundamentales, culminó en 2007. En este artículo revisamos el tratamiento de uno de los aspectos que ha supuesto más modificaciones conceptuales en su contabilización, el impuesto de sociedades, tal como deberá ser reflejado en las cuentas que se preparen sobre los ejercicios iniciados a partir del 1 de enero de 2008.

In a recent paper Leong-Huang:2010 {Journal of Applied Statistics 37, 215–233} proposed a wavelet-correlation-based approach to test for cointegration between two time series. However, correlation and cointegration are two different concepts even when wavelet analysis is used. It is known that statistics based on nonstationary integrated variables have non-standard asymptotic distributions. However, wavelet analysis offsets the integrating order of nonstationary series so that traditional asymptotics on stationary variables suffices to ascertain the statistical properties of wavelet-based statistics. Based on this, this note shows that wavelet correlations cannot be used as a test of cointegration.

The hydrological response of a catchment to rainfall on different timescales is result of a complex system involving a range of physical processes which may operate simultaneously and have different spatial and temporal influences. This paper presents the analysis of streamflow response of a small humid-temperate catchment (Aixola, 4.8 km(2)) in the Basque Country on different timescales and discusses the role of the controlling factors. Firstly, daily time series analysis was used to establish a hypothesis on the general functioning of the catchment through the relationship between precipitation and discharge on an annual and multiannual scale (2003-2008). Second, rainfall-runoff relationships and relationships among several hydrological variables, including catchment antecedent conditions, were explored at the event scale (222 events) to check and improve the hypothesis. Finally, the evolution of electrical conductivity (EC) during some of the monitored storm events (28 events) was examined to identify the time origin of waters. Quick response of the catchment to almost all the rainfall events as well as a considerable regulation capacity was deduced from the correlation and spectral analyses. These results agree with runoff event scale data analysis; however, the event analysis revealed the non-linearity of the system, as antecedent conditions play a significant role in this catchment. Further, analysis at the event scale made possible to clarify factors controlling (precipitation, precipitation intensity and initial discharge) the different aspects of the runoff response (runoff coefficient and discharge increase) for this catchment. Finally, the evolution of EC of the waters enabled the time origin (event or pre-event waters) of the quickflow to be established; specifically, the conductivity showed that pre-event waters usually represent a high percentage of the total discharge during runoff peaks. The importance of soil waters in the catchment is being studied more deeply.
