- The neural cell adhesion molecule (NCAM) is required for cell type segregation during pancreatic islet organogenesis. We have investigated the functional consequences of ablating NCAM on pancreatic beta-cell function. In vivo, NCAM(-/-) mice exhibit impaired glucose tolerance and basal hyperinsulinemia. Insulin secretion from isolated NCAM(-/-) islets is enhanced at glucose concentrations below 15 mM but inhibited at higher concentrations. Glucagon secretion from pancreatic alpha-cells evoked by low glucose was also severely impaired in NCAM(-/-) islets. The diminution of insulin secretion is not attributable to defective glucose metabolism or glucose sensing (documented as glucose-induced changes in intracellular Ca(2+) and K(ATP)-channel activity). Resting K(ATP) conductance was lower in NCAM(-/-) beta-cells than wild-type cells, and this difference was abolished when F-actin was disrupted by cytochalasin D (1 muM). In wild-type beta-cells, the submembrane actin network disassembles within 10 min during glucose stimulation (30 mM), an effect not seen in NCAM(-/-) beta-cells. Cytochalasin D eliminated this difference and normalized insulin and glucagon secretion in NCAM(-/-) islets. Capacitance measurements of exocytosis indicate that replenishment of the readily releasable granule pool is suppressed in NCAM(-/-) alpha- and beta-cells. Our data suggest that remodeling of the submembrane actin network is critical to normal glucose regulation of both insulin and glucagon secretion.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- We lack knowledge concerning the importance of entrepreneurial actors in development of dynamic capabilities. Entrepreneurial drives lead the entrepreneur and his/her firm into different strategies to cope with encompassing change and in building different sets of capabilities. A case study of four high-tech firms suggests that entrepreneurial actions determined by entrepreneurial drives (technological, market, business, and development) lead to the creation of new modules and to combinations of external and internal capabilities that increase the balance between contradicting demands. This suggests that a combination of different drives is important, as is the formation of entrepreneurial roles (creators, expanders, and builders).

Dynamics of B2B brand equity formation : An empirical comparison between uni- and multi-service buyers
- 2009

Konferensbidrag (refereegranskat)abstract
- The main purpose of the study is to investigate the dynamics of brand equity formation in the business-to-business setting. The study focuses on examining the potential differences in the formation of brand equity between the customers, who have chosen to buy only the core service, versus the customers, who have decided to buy a diverse range of services from their current provider of professional services.

Satisfaction and brand equity : an empirical analysis of the effects in the B2B setting
- 2009
-
Ingår i: Proceeding of the 38th EMAC Conference. - : European Marketing Academy.
-
Konferensbidrag (refereegranskat)abstract
- The main purpose of the study is to examine the causal relationships between satisfaction and the dimensions of brand equity. Despite the importance that customer satisfaction and brand equity have for the company’s success, the causal relationships between these concepts were not investigated in previous research. Considering the hierarchical effects between the brand equity dimensions, the conceptual framework examines the relationships between satisfaction and brand equity in the business-to-business setting. Confirmatory factor analysis indicates significant positive effects of satisfaction on brand awareness, brand associations, and brand loyalty. The important link between perceived quality, satisfaction, and brand loyalty is confirmed in this study.

The impact of customer experience on brand equity : a communal relationships norms perspective

Konferensbidrag (refereegranskat)abstract
- The main purpose of the study is to investigate the impact of customer experience on different dimensions of brand equity. The study employs a customer-based approach for conceptualizing brand equity. The conceptual model illustrates the impact of customer experience on the formation of brand equity, which is assessed through a hierarchy of effects between the brand equity dimensions. Structural equation modeling is used to perform a confirmatory factor analysis testing the significance of the proposed model in the business-to-business setting.
