Alignment of strategy and structure in local government
2020
Strategic positioning and structural alignment in the public sector is a neglected area of research. This paper analyses the strategic positions of prospectors, defenders and reactors and structural alignment in Norwegian municipalities. Top managers responding to a survey perceived that the municipalities did align their organizational structures to the strategic positions for prospectors and defenders, but not for reactors, as hypothesized, but these relationships were modest. The top managers often found it difficult to provide consistent responses on their organizations’ choices of strategic positions. The authors show that many Norwegian municipalities have minimal alignment of their o…
A novel approach to investigate the evolution of structured tandem repeat protein families by exon duplication.
2020
Tandem Repeat Proteins (TRPs) are ubiquitous in cells and are enriched in eukaryotes. They contributed to the evolution of organism complexity, specializing for functions that require quick adaptability such as immunity-related functions. To investigate the hypothesis of repeat protein evolution through exon duplication and rearrangement, we designed a tool to analyze the relationships between exon/intron patterns and structural symmetries. The tool allows comparison of the structure fragments as defined by exon/intron boundaries from Ensembl against the structural element repetitions from RepeatsDB. The all-against-all pairwise structural alignment between fragments and comparison of the t…
Assessment of the probabilities for evolutionary structural changes in protein folds.
2007
Abstract Motivation: The evolution of protein sequences can be described by a stepwise process, where each step involves changes of a few amino acids. In a similar manner, the evolution of protein folds can be at least partially described by an analogous process, where each step involves comparatively simple changes affecting few secondary structure elements. A number of such evolution steps, justified by biologically confirmed examples, have previously been proposed by other researchers. However, unlike the situation with sequences, as far as we know there have been no attempts to estimate the comparative probabilities for different kinds of such structural changes. Results: We have tried …
