Philipp Wiegandt empirically analyzes the effects the creation of a firm-established brand community has on the brand loyalty and word-of-mouth communication of its members over time. He finds that establishing a firm-established brand community creates value for both – the company and their customers.
The field of DNA vaccines has undergone explosive growth in the last few years. As usual, some historical precursors of this approach can be d- cerned in the scientific literature of the last decades. However, the present state of affairs appears to date from observations made discreetly in 1988 by Wolff, Malone, Felgner, and colleagues, which were described in a 1989 patent and published in 1990. Quite surprisingly, they showed that genes carried by pure plasmid DNA and injected in a saline solution, hence the epithet “naked DNA,” could be taken up and expressed by skeletal muscle cells with a low but reproducible frequency. Such a simple methodology was sure to spawn many applications....
Creativity in organizations has become a key topic of organizational research. This work expands on existing research by exploring creativity in the dynamics of social networks. Collective creativity is introduced as a central part of organizational learning and seen as the expression of creativity on the collective level. The research is able to empirically assess creativity in the development of social structures. For the assessment of creativity this work applies a longitudinal study design by combining social network analysis with creativity studies. The approach enables to relate creativity indicators with social network measures. It is based on an empirical study of innovation projects in the automotive industry and thereby extends existing research and theories on creativity, social network dynamics and organizational learning.

In the early 1990s, almost 200 yr after Edward Jenner demonstrated the effectiveness of the smallpox vaccine, a new paradigm for vaccination emerged. The conventional method of vaccination required delivery of whole pathogens or structural subunits, but in this new approach, DNA or genetic information was administered to elicit an immunological response. Once it was observed that plasmid DNA delivered in vivo led to production of an encoded transgene (1), two ground-breaking studies demonstrated that immunological responses could be generated against antigenic transgenes via plasmid DNA delivered by DNA vaccination (as this approach is called) (2,3). The appe- ance of this new vaccination st...
First multi-year cumulation covers six years: 1965-70.
Georges Köhler was one of the most prominent German scientists of recent history. In 1984, at an age of 38, he received the Nobel Prize in Physiology or Medicine, together with N.K. Jerne and C. Milstein, for inventing the technique for generating monoclonal antibodies. This method and its subsequent applications had an enormous impact on basic research, medicine and the biotech industry. In the same year, Köhler became one of the directors of the Max-Planck-Institute of Immunobiology in Freiburg; his unfortunate premature death in 1995 set an end to his extraordinary career. Prof. Klaus Eichmann, who had invited Köhler to become his codirector, is one of the people who were closest to him. This scientific biography commemorates the 10th anniversary of Köhler's untimely death. Köhler's scientific achievements are explained in a way to make them understandable for the general public and discussed in the historical context of immunological research.
Genetic / DNA immunization represents a novel approach to vaccine and immune therapeutic development. The direct injec tion of nucleic acid expression cassettes into a living host results in a limited number of its cells becoming factories for production of the introduced gene products. This host-inappropriate gene expression has important immunological consequences, resulting in the specific immune activation of the host against the gene delivered antigen. The recent demonstration by a number of laboratories that the induced immune responses are functional in experimental models against both specific infectious diseases and cancers is likely to have dramatic consequences for the develop men...
Products of gene modification have vast implications. Creating public awareness and disseminating information on the subject seeks to demystify some of the widely held falsehoods regarding genetically modified products. This an informative, thorough and easy-to-understand guide book that aims to enlighten and debunk some of the commonly held misconceptions on products of gene modification and to give the reader a better understanding of the role genetic modification will play. The review sheds light on the safety, and application of these products in medicine, the food industry and other areas, especially those where genetic modification may represent a cheap, faster, credible and viable alternative in achieving sustainable development amongst resource-poor communities.
This is the first book specializing in plasmids and their biomedical use, including all relevant aspects of production, applications, quality, and regulations. Readers will discover clinical applications for the wide range of preventive and therapeutic applications using plasmid DNA. The book describes modified vector systems based on plasmids, as well as the potency of genomic research and vector design by informatics. Using the example of fish vaccination, the application of DNA vaccination in veterinary health care is reviewed, followed by a detailed overview of plasmid production technology on an industrial scale. Finally, the book considers regulatory and quality assurance aspects of such new drugs plus thire market potential.
