Patterns of nutrient exchange in a riverine mangrove forest in the Shark River Estuary, Florida, USA

This study aimed to evaluate tidal and seasonal variations in concentrations and fluxes of nitrogen (NH4 +, NO2+NO3, total nitrogen) and phosphorus (soluble reactive phosphorus, total phosphorus) in a riverine mangrove forest using the flume technique during the dry (May, December 2003) and rainy (October 2003) seasons in the Shark River Estuary, Florida. Tidal water temperatures during the sampling period were on average 29.4 (± 0.4) oC in May and October declining to 20 oC (± 4) in December. Salinity values remained constant in May (28 ± 0.12 PSU), whereas salinity in October and December ranged from 6‒21 PSU and 9‒25 PSU, respectively. Nitrate + nitrite (N+N) and NH4+ concentrations ranged from 0.0 to 3.5 μM and from 0 to 4.8 μM throughout the study period, respectively. Mean TN concentrations in October and December were 39 (±0.8) μM and 37 (±1.5) μM, respectively. SRP and N+N concentrations in the flume increased with higher frequency in flooding tides. TP concentrations ranged between 0.2‒2.9 μM with higher concentrations in the dry season than in the rainy season. Mean concentrations were <1. 5 μM during the sampling period in October (0.75 ± 0.02) and December (0.76 ± 0.01), and were relatively constant in both upstream and downstream locations of the flume. Water residence time in the flume (25 m2) was relatively short for any nutrient exchange to occur between the water column and the forest floor. However, the distinct seasonality in nutrient concentrations in the flume and adjacent tidal creek indicate that the Gulf of Mexico is the main source of SRP and N+N into the mangrove forest.

Risorse idriche sotterranee del continente africano: disponibilità e prospettive di gestione

L’acqua è uno dei principali fattori per la crescita socio-economica e lo sviluppo del continente africano. Il continente africano dispone di ingenti risorse idriche, ma le complessità naturali caratteristiche di alcune regioni del continente e la frequente assenza di una corretta pianificazione della loro gestione ne riduce ad oggi il potenziale in maniera significativa. L’utilizzo delle risorse idriche in Africa è destinato ad incrementare sensibilmente nel corso dei prossimi decenni, come risultato della crescita demografica e dei fabbisogni nell’agricoltura. Le risorse idriche sotterranee giocano un importante ruolo in tale scenario in quanto molti paesi africani caratterizzati da scarsità d’acqua dispongono di sostanziali riserve idriche sotterranee e l’accesso a tali risorse, ancorché limitate, è largamente diffuso nel continente. Si stima che il totale delle risorse idriche sotterranee sia di 0,66 milioni di km cubi. Le risorse sotterranee sono largamente distribuite: i maggiori volumi sono localizzati nei larghi acquiferi sedimentari nelle regioni del nord Africa. Per molti paesi africani pozzi appropriatamente ubicati sono in grado di sostenere le comunità con l’estrazione manuale mediante pompe con una portata di 0,1-0,3 l/s. Grandi impianti di produzione da acquifero (>5 l/s), che siano adatti per lo sviluppo urbano o produzioni agricole intensive, non sono ancora diffusi e sono limitati ad aree particolari. La disponibilità ed accessibilità delle acque sotterranee in gran parte dell’Africa è favorevole ad uno sviluppo rurale piuttosto che urbano. Il maggiore fattore limitante per una gestione sostenibile delle risorse sotterranee è dato dalla necessità di identificare se le acque sotterranee sono rinnovabili (ed in quale misura) o meno, al fine di programmare le corrette politiche gestionali nel tempo.

La Unión Europea y el regionalismo latinoamericano: un balance

El apoyo a la integración y el regionalismo es uno de los rasgos distintivos del diálogo político y cooperación entre la UE y América Latina y el Caribe. Este artículo examina la racionalidad, objetivos e instrumentos de apoyo de la UE al regionalismo y la integración latinoamericana y, en particular, los incentivos generados por los Acuerdos de Asociación y el papel de la cooperación regional y subregional. Aunque han sido instrumentos efectivos, la falta de cohesión interna de los grupos regionales de América Latina y los problemas de coherencia de políticas de la UE han limitado su impacto y efectividad. A partir de las enseñanzas extraidas de esa experiencia, se propone una estrategia ampliada de apoyo para el nuevo ciclo de programación de la cooperación de la UE del periodo 2014-2020.

Effect of reading sport chronicles on the perception of justice and the predisposition to protest actions in soccer

In this study three chronicles from national newspapers (one generalist and two sport press) were analyzed. The chronicles belong to Spain’s soccer final of the King’s Cup in 2014. The aim of the study was to know if there was any influence on the readers’ perception of justice and consequently if this influence could cause a particular predisposition to participate in acts of protest. 462 university students participated. The results showed that different chronicles caused differences in the perception of justice depending on the chronicle read. However, a clear influence on the willingness to participate in acts of protest was not obtained. These results should make us think about the impact of sport press and its influence, and to be aware of the indirect responsibility of every sector on the antisocial behaviors generated by soccer in our country.

From Pro-Franco to Anti-Government. The Evolution of the "Sur" regarding National Politics during the Spanish Transition (1975-1978)

The Spanish transition, the political process through which Spain ceased to be a dictatorship to become a democracy, was accompanied by the dissolution of the National Movement, the institutional support for the chain of the Movement Press from its beginnings, in April 1977. This fact, among others, contributed to the /Sur/, the regional reference newspaper for the chain in Andalusia, evolving both structurally and ideologically to adapt itself to the new political regime. This study applies content analysis to editorials, articles and columns published by the newspaper between 1975 and 1978, exploring the process through which the regional newspaper edited in Málaga abandoned its propaganda function with regard to the Government, considering it undemocratic, and supported the PSOE, presenting it as the best alternative to the UCD in the Spanish Executive, thus taking on its role as a political agent.

La situación de los museos españoles ante la crisis. El patrimonio implicado

La crisis como coyuntura y tránsito a una nueva situación, y el cambio social que parece conllevar, lejos de ser un fenómeno exclusivamente actual, viene acompañando a los museos españoles desde décadas atrás, debido a indecisiones, faltas de planificación, cambios políticos y de estrategias de funcionamiento. Pero será a partir de la Transición democrática, y la década de 1980, en que comenzará a fraguarse la llamada “burbuja” de los museos, que estalla bajo el “efecto Guggenheim” a finales del siglo XX, seguida de la merma de presupuestos oficiales para el sostenimiento del sistema museístico que trae como consecuencia la tan mencionada “crisis” económica desde aproximadamente 2008. El artículo examina esta situación y advierte de que el momento delicado que viven los museos en la actualidad es ocasión para replantearse su futuro y adaptarse a una nueva realidad cambiante. El Museo Etnológico de Navarra “Julio Caro Baroja” constituye un caso de adaptación a tales circunstancias.

Comercialización de quesos especiales : estrategias para mejorar la inserción del queso de oveja en el mercado

Los quesos de oveja son un producto de especialidad de escaso desarrollo en la Argentina. Si bien existe una demanda potencial de este producto que representa una oportunidad tanto para el mercado interno como para el externo, existe una serie de desarticulaciones en la cadena, así como una dificultad comercial que restringe el encuentro entre el consumidor y el producto. Conocer las preferencias del consumidor de un producto de especialidad, es el primer paso para orientar las estrategias que colaboren con la comercialización de un producto. El objetivo del presente trabajo, es estudiar las preferencias del mercado actual y potencial de quesos de oveja, en el ámbito de la Ciudad Autónoma de Buenos Aires, a fin de proponer/identificar estrategias comerciales que permitan de mejorar la inserción y el posicionamiento del queso de oveja argentino. La metodología empleada para realizar el presente trabajo se basó en métodos cualitativos y cuantitativos, estructurándose de forma similar a un plan de Marketing, partiendo de un diagnóstico del macroambiente y del microambiente sobre los cuales se diseñó el plan de marketing estratégico y opertativo (o táctico). De lo analizado, se observa que la demanda ávida de quesos de oveja al día de hoy no puede ser cubierta con un producto gourmet nacional por falta de oferta, desarrollo y posicionamiento del producto. Para cubrir este problema se han propuesto, desde el lado del desarrollo del producto, distintas alternativas a fin de mejorar el posicionamiento del y poder cumplir con lo que exige la demanda. Se concluye que será necesario trabajar previamente sobre aspectos productivos (cantidad y calidad de la oferta de leche y quesos de oveja) como paso previo a la implementación de las propuestas realizadas en este estudio.
