- Background We have developed genomic tools to allow the genus Populus (aspens and cottonwoods) to be exploited as a full-featured model for investigating fundamental aspects of tree biology. We have undertaken large-scale expressed sequence tag (EST) sequencing programs and created Populus microarrays with significant gene coverage. One of the important aspects of plant biology that cannot be studied in annual plants is the gene activity involved in the induction of autumn leaf senescence. Results On the basis of 36,354 Populus ESTs, obtained from seven cDNA libraries, we have created a DNA microarray consisting of 13,490 clones, spotted in duplicate. Of these clones, 12,376 (92%) were confirmed by resequencing and all sequences were annotated and functionally classified. Here we have used the microarray to study transcript abundance in leaves of a free-growing aspen tree (Populus tremula) in northern Sweden during natural autumn senescence. Of the 13,490 spotted clones, 3,792 represented genes with significant expression in all leaf samples from the seven studied dates. Conclusions We observed a major shift in gene expression, coinciding with massive chlorophyll degradation, that reflected a shift from photosynthetic competence to energy generation by mitochondrial respiration, oxidation of fatty acids and nutrient mobilization. Autumn senescence had much in common with senescence in annual plants; for example many proteases were induced. We also found evidence for increased transcriptional activity before the appearance of visible signs of senescence, presumably preparing the leaf for degradation of its components.

Predicting spontaneous termination of atrial fibrillation with time-frequency information

- Our approach to predicting spontaneous termination of atrial fibrillation (AF) is based on parameters derived from the time-frequency distribution of the residual ECG signal, resulting from spatiotemporal cancellation of QRST complexes. Each consecutive, logarithmically scaled spectrum of the time-frequency distribution of the residual ECG is modeled as a frequency shifted and amplitude scaled version of a spectral profile. Parameters characterizing AF, such as fundamental frequency, amplitude, and waveform of the fibrillation waves, are then extracted from the spectral profile. The waveform of the spectral profile is used to distinguish AF from sinus rhythm and noise, so that occasional episodes of sinus rhythm and noise can be excluded. Using these parameters, 95% of the ECGs from the training set, and 90% from the test set was correctly classified as non-terminating and terminating AF respectively.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Companies in the business-to-business segment increasingly try to expand their product offerings into customer solutions offerings. This often implies adding value through professional services such as systems integration and business consulting related to the parent organization’s products. The addition of a consultative component to the product business both poses new challenges and provides new possibilities for the product organization’s innovation processes. We argue that corporate consulting units provide a vital source of knowledge for organizations seeking to increase their innovation capacity by learning about and from their customers. The current paper discusses the knowledge created in such consulting business as well as the filters that hinder utilizing this knowledge in the innovation processes of the product-oriented organization.

Handling multiple identities in boundary spanning : a study of identity construction in a corporate consulting unit
- 2002
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The developments towards what is often called the postindustrial society carry with them a blurring of organizational boundaries. Value is increasingly created in organizational constellations such as joint ventures, corporate consulting units and partnerships crossing traditional firm boundaries. This paper addresses the blurring of firm boundaries from an organizational identity perspective and focuses identity formation and identification in complex boundary spanning organizations. Based on a study of organizational identity in a corporate consulting unit, we explore the constitution and the organization members' handling of multiple identities. The specific constitution of multiple identities in boundary spanning organizations is discussed, and it is concluded, that holographic multiple identities represent an unstable arrangement striving towards a clear identity. The necessity for management to actively manage multiple identities is pointed at, and possible approaches are discussed.

Bokkapitel (refereegranskat)abstract
- “We offer customer solutions, not just products” is a common formulation in mission statements of many organizations today. The growing interest in a customer solutions strategy is based on the increasing service content in many organizations’ offerings (Normann, 2001); increased business complexity, privatization, and outsourcing (Davies et al., 2001); and means of moving the business focus from the products to the customers (Hax & Wilde, 1999; Vandermerwe, 2000). In the business-to-business segment, the customer-centric logic of a solutions business is often represented in a stand-alone consulting business. Based on Good (1985), we use the term corporate consulting to designate this type of consulting unit. IBM is often cited as an illustration of a firm that has successfully transformed itself from a provider of hardware-based products to more software-based services (see, e.g., Normann, 2001; Vandermerwe, 2000). The “new” IBM is built around the service organization IBM Global Services, a corporate consultancy in part, which accounts for approximately 40% of IBM's total revenues. More important, the services provided, such as business consulting, information technology (IT) consulting, and outsourcing, are seen as a central mechanism for leveraging the technological capabilities of the parent organization.

Tidskriftsartikel (refereegranskat)abstract
- For many product-oriented companies, establishing a corporate consultancy can be a good first step toward a more solutions-based orientation. As Ericsson, Shell and AT&T, among others, illustrate, the consulting unit can take a number of forms dictated by its key knowledge and its relation to the product businesses' value chain. The challenge is to determine how similar the consulting unit should be to the parent company in identity, mission and structure. Expert corporate consultancies support the product business by exploiting professional knowledge. Their choice of strategy depends on the nature of the ties between the product business and the consultancy. The four types of corporate consultancy - spearhead, expert, integration and know-how - are continuous rather than rigid. Some consultancies switch types as their mission changes. For managers, engaging in a solutions strategy by establishing corporate consultancies means building a conflict into their organization, a conflict between a product-oriented logic and a customer-oriented one.
