Brand management in media crisis

Due to the turbulent and chaotic economic climate over the entire advertising industry, the TV stations, and particularly those in Romania, face a critical challenge in terms of dealing with an unprecedented crisis within this market. Since the last quarter of 2008, the Romanian advertising market is going through a serious phase of contraction and reconfiguration.One of the causes is the strong connection with the other similar markets within the Central and Eastern Europe, as well as with those from the West, which face the same decline. Several important publications were closed during 2009 and the beginning of 2010, together with higher unemployment in the media sector and major changes of the biggest media groups strategies. This paper aims to portrait the perspective of the TV Brand Managers in the center of a challenging environment, both in the organizations and in the overall market.   

Investigation of Ammonia Transport Pathways in the Anal Papillae of Larval Aedes Aegypti Mosquito

The anal papillae of Aedes aegypti larvae, are important sites of ammonia/ammonium excretion. They express three putative ammonia (NH3/NH4+) transporters, Rhesus proteins AeRh50-1, AeRh50-2 and AeAmt. Ammonium concentration gradients were measured adjacent to the anal papillae using scanning ion-selective electrode technique (SIET). Results suggest that the ionomotive pumps V-type H+ ATPase (VA) and Na+/K+ ATPase (NKA) as well as cation / H+ exchanger, isoform 3 (NHE3) participate in ammonia excretion at the anal papillae. VA is involved in ammonia trapping at the exterior unstirred layer of the anal papillae, while basal NKA and apical NHE3 facilitate the transport of NH4+. Quantitative RT-PCR analysis revealed differential abundances of AeRh-2 and Amt in the anal papillae relative to the abundance of AeRh50-1. In presence of HEA both Rhs were down regulated but Amt was up regulated. It is the conclusion of this study that these transporters work in consortium to regulate ammonia
