What makes a brand manager effective? ☆

Keywords: Brand management Intangible capital Capabilities Brand manager SEM Brands have become increasingly important as a foundation for competitive strategy. Unfortunately, although brand managers are responsible for brand strategy development and execution, little is known about what makes a brand manager effective. A model is developed to understand what intangible capital embodied by brand managers influences brand management capabilities and resultant brand performance. Measures of brand manager intangible capital and brand management capabilities are developed through an iterative scale development process. Hypothesis testing, derived from a survey of brand managers, indicates that brand manager human, relational and informational capital influences brand management capabilities and resultant brand performance, and brand manager intangible capital has an indirect effect on brand performance via brand management capabilities. By delineating and operationalizing the intangible capital and capabilities of brand managers, this study provides a theoretical and empirical foundation for future research on brand managers, tools for assessing current brand manager capital and capabilities, and guidance in relation to intangible capital and capabilities needed by brand managers

Electrosprayed core-shell nanoparticles of PVP and shellac for furnishing biphasic controlled release of ferulic acid

Coaxial electrospraying was explored to organize polymer excipients in a core-shell manner for providing biphasic controlled release of active ingredient. With ferulic acid (FA) as a model drug, and shellac and polyvinylpyrrolidone (PVP) as the core and shell polymeric matrices, core-shell nanoparticles were successfully fabricated. A series of tests were carried out to characterize the prepared core-shell nanoparticles and also the nanoparticles prepared using a single fluid electrospraying of the shell or core fluids alone. The core-shell nanoparticles had an average diameter of 530 ± 80 nm with clear core-shell structure. The contained FA was converted to an amorphous state both in the core and the shell parts due to the favorable hydrogen bonding between the components. In vitro dissolution tests demonstrated that the core-shell nanoparticles were able to provide the desired biphasic drug-controlled release profiles. Coaxial electrospraying is a useful tool for the development of novel nanodrug delivery systems from polymers

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
