To address this issue, we have conceptualized the “Online Reputation Chain†as a metaphor for understanding social. differing needs and practices across the organization that affect the understanding of social media value and use, as well as how social media fits with overall communication strategy planning. These diverse perspectives lead to tensions between. because of the diversity in perspectives about how social media should be deployed among competing department perspectives in an organization are generally not explicitly considered when internal and external communication are dealt with separately. Social Media studies tend to focus on either internal (Friedl & VerÄiÄ, 2011 Huang et al, 2013) or external communication (Briones et al, 2011 Hanna et al, 2011 Saschi, 2012 Byrd, 2012 Kilgour et al, 2015), rather than addressing social media across the organization. Kampf, Constance Elizabeth Mohammadreza, Marjan The results indicated that diclofenac imprinted polymer could be used as a pH-responsive matrix in preparation of a new drug delivery system for diclofenac.
The data showed that imprinted polymer, prepared by MAA had superior properties, in comparison with other polymers, for minimum release (14%) of drug in gastric acid and maximum release (90%) in basic condition. Our results proved that all polymers represented pH-responsive diclofenac delivery at above conditions. Duo to the stronger non-specific bounds in aqueous solutions, IF values decreased in water compared to acetonitrile as an organic medium. The results indicated the specific binding of diclofenac to imprinted polymers. Diclofenac release in aqueous solvents at pH values of 1.5, 6.0 and 8.0, simulating gastrointestinal fluids, were also studied. Binding properties and imprinting factor (IF) of MIPs were studied in comparison with their non-imprinted ones (Blank) in organic and aqueous media. Methacrylic acid (MAA), methacrylamide (MAAM) and 4-vinyl pyridine (4VP) were tested as functional monomers and ethylene glycole dimethacrylate (EDMA) was used as a cross-linker monomer in polymeric feed. Three different molecularly imprinted polymers (MIPs) for drug delivery of diclofenac in gastrointestinal tract were synthesized employing bulk polymerization method and their binding and release properties were studied in different pH values.

Four MOML projects in Hong Kong were selected for examination. This article coins media education initiatives by media organizations with the term " media-organization media literac"y (MOML). Media Education Initiatives by Media Organizations: The Uses of Media Literacy in Hong Kong MediaĪs more media organizations have engaged in media education, this paper investigates the goals and practices of these activities. The re-use of organic wastes requires value added processing such as composting, co-composting, digestion, fractioning/sieving, pressing, binding, stabilising by Public pressure to use peat alternatives in horticultural rooting media offers room for the re-use of local organic waste materials.
