ACTUAL PROBLEMS OF ENTERPRISES’ MARKETING MANAGEMENT

2021

The purpose of this paper is to provide an overview of the most current problems and issues in marketing management. As all enterprises deal with various difficulties in their business planning, implementation and control, these issues and problems have to be recognized, dealt with, and solved. Most of the business strains will have a lot to do with diverse marketing aspects, as marketing is the main link between enterprises and their markets and customers; strategically mappedand implemented marketing helps to create competitive advantage and pave the way for success, but different problems can endanger firms’ marketing process, thus in today’s volatile business environment marketing execu…

Soil and water losses from new citrus orchards growing on sloped soils in the western Mediterranean basin

2009

Ten representative research sites were selected in eastern Spain to assess soil erosion rates and processes in new citrus orchards on sloping soils. The experimental plots were located at representatives sites on limestone, in areas with 498 to 715 mm year−1 mean annual rainfall, north-facing slopes, herbicide treated, and new (less than 3 years old) plantations. Ten rainfall simulation experiments (1 h at 55 mm h−1 on 0·25 m2 plots) were carried out at each of the 10 selected study sites to determine the interill soil erosion and runoff rates. The 100 rainfall simulation tests (10 × 10 m) showed that ponding and runoff occurred in all the plots, and quickly: 121 and 195 s, respectively, fo…

Discovery of hard phase lags in the pulsed emission of GRO J1744-28

2016

We report on the discovery and energy dependence of hard phase lags in the 2.14 Hz pulsed profiles of GRO J1744-28. We used data from XMM-Newton and NuSTAR. We were able to well constrain the lag spectrum with respect to the softest (0.3--2.3 keV) band: the delay shows increasing lag values reaching a maximum delay of $\sim$ 12 ms, between 6 and 6.4 keV. After this maximum, the value of the hard lag drops to 7 ms, followed by a recovery to a plateau at 9 ms for energies above 8 keV. NuSTAR data confirm this trend up to 30 keV, but the measurements are statistically poorer, and therefore, less constraining. The lag-energy pattern up to the discontinuity is well described by a logarithmic fun…

Una aproximació a l'envelliment harmònic des de la psicogerontologia: revisió i propostes

2015

Es realitza una revisió sistemàtica de la bibliografia per aproximar-nos a un nou concepte relacionat amb el procés d'envellir, dins de les tendències de l'envelliment positiu: l'envelliment harmònic (Liang i Luo, 2012). Es cita el concepte d'envelliment exitós de Rowe i Kahn (1997) i les crítiques a aquest model realitzades per Liang i Luo (2012) i de Waid i Leslie (2003), per a introduir els avantatges del concepte d'envelliment harmònic. S'ha analitzat la producció científica dels últims 10 anys sobre envelliment harmònic i altres conceptes relacionats amb el bon envellir: envelliment exitós, saludable, actiu, òptim i productiu. Aquests termes centren la recerca: esperança, espiritualita…

Seismic and sedimentologic features of Oxfordian-Kimmeridgian syn-rift sediments on the eastern margin of the Lusitanian Basin

1989

Following deposition of widespread middle Oxfordian lacustrine carbonates and evaporites, the Lusitanian Basin was differentiated into a number of sub-basins. The Arruda sub-basin is a half graben basin situated some 30 km north of Lisbon. It accumulated over 2.5 km of Kimmeridgian siliciclastic sediments, and is bounded to the east by the Vila Franca de Xira fault zone. Carbonate deposition persisted over horsts along the fault zone from the Oxfordian to the early Kimmeridgian, and in places to the late Kimmeridgian, and shows a pronounced west-east facies zonation, with higher energy framestones and grainstones accumulating along the exposed western margins. Seismic data indicate a major …

Comments to the paper "do we really need new medical information about the Turin Shroud?".

2015

Abstract Following the interesting arguments raised in a recent letter to the editor, about a paper recently published in this journal, the authors are happy to take a cue from them to clarify some facts that have not been sufficiently treated for space. After a description of the methods used, arguments regarding a blunt trauma on the right shoulder with consequent dislocation, the position of the hands on the pubis with brachial plexus injury, and the wrist nailing that caused retracted thumbs are discussed in detail.

Field investigation on rilling in the experimental Sparacia area, South Italy

2008

In this paper the results of a field investigation on rilling carried out in the experimental Sparacia area are reported. The measurements were made on a plot 6 m wide and 22 m long subjected to natural rainfalls. For ten rainfalls the total soil loss (interrill and rill erosion) was collected in a storage system consisting of two tanks arranged in series at the base of the plot. Rill morphology (rill length and cross-sections) was measured for five rainfall events, while the rill profile was surveyed for three events. First the contribution of each component (rill and interrill erosion) to total soil loss was established. Then the analysis allowed establishment of a power relationship betw…

Evolución de episodios pluviométricos en la Demarcación Hidrográfica del Júcar (1989-2016): del recurso al riesgo

2020

Este trabajo aborda la clasificación y evolución diacrónica de los episodios de lluvia (1989-2016) en ambientes mediterráneos, en la Demarcación Hidrográfica del Júcar. En base a datos del SAIH, y siguiendo criterios hidrológicos, se seleccionan 698 episodios, que se caracterizan con indicadores de precipitación acumulada, intensidad y persistencia. Mediante un análisis cluster se identifican tres tipologías (episodios de recurso limitado, de gran recurso a largo plazo y de riesgo) y se analiza su evolución temporal, estableciendo diferencias entre los episodios de interior y de litoral. Los resultados muestran una tendencia hacia el incremento del riesgo en detrimento del recurso en los tr…

The look of Gerda Taro and Robert Capa during the Second International Congress of Writers in Defense of Culture

2016

RESUMEN: El Segundo Congreso Internacional de Escritores para la Defensa de la Cultura celebrado en Valencia durante la Guerra Civil Española desvió la mirada mundial hacia la ciudad. El acontecimiento atrajo a un gran número de intelectuales y corresponsales extranjeros, entre ellos los fotoperiodistas Gerda Taro y Robert Capa, que documentaron juntos el acto de inauguración el día 4 de julio de 1937. A través del análisis pormenorizado de una fotografía realizada por Gerda Taro a la escritora Anna Seghers, este artículo realiza una lectura del contexto los días en los que Valencia se convirtió en el centro mundial de la intelectualidad antifascista. ABSTRACT: The Second International Cong…
