Service sector firms have long been neglected in innovation studies despite their increasing importance for economy. However, recent research has revealed that service firms do innovate although they follow distinct paths and reach different outcomes than those of the manufacturing sector. Measuring the effects of innovation on performance has thus become an essential concern for both policy‐makers and business leaders. This dissertation specifically contributes to the current debate on the effects of innovation on performance at firm‐level in the service sector by shedding more light on the characteristics of these complex relationships and by defining its underlying mechanisms. For these purposes, an intellectual capital perspective is adopted. This dissertation first takes a broad sector approach to services, focusing on potentially innovative core service activities, and relying on the concept of relational capital, it explores the most commonly reported feature of innovation in services, which is the openness of the innovation process. As prior research indicates that there is a diversity of innovation patterns in services, the dissertation then concentrates on financial service firms. Besides their own significance, financial firms play a critical role in the proper functioning of the entire economy. Focusing on this specific industry, the dissertation further delineates the innovation process into its constitutive elements, referring to human, structural and relational capital concepts. The setting for most of the empirical studies is Luxembourg, which allows benefitting from the peculiarities of this small, open, international but highly innovative economy dominated by service firms. This dissertation mainly concludes that adopting an open strategy for innovation activities brings differentiated results according to the partners involved, with some contrast observed between market, science and competitor co‐operation. When examining how resources mobilized in the innovation process interact to affect performance in financial services, the dominant role of relational capital emerges. Furthermore, the examination unveils the interaction effects between the constitutive elements of intellectual capital and confirms the importance of the orientation towards innovation, in its various facets, in financial firms. Overall, this dissertation shows that adopting an intellectual capital perspective to understand the innovation process, to reveal its main ingredients and to disentangle its effects on performance can be insightful.

Carried out into an interpretative perspective (Thiétart, 2003), the present research has as an objective to fill the gaps identified in previous literature in order to make further progress in the prevention of business failure. On the basis of a conceptual model of the (small) business failure process which integrates previous research, this research gathers empirical evidence on distinctive explanatory business failure patterns amongst small firms. Five main explanatory business failure patterns are identified amongst a sample of 203 small distressed firms and some relationships between these patterns and specific financial indicators are then tested. Besides its scientific outputs, this research aims at providing key actors in the prevention of small business failures (such as the Courts of Commerce, Local Organizations concerned with small businesses, consultants or entrepreneurs) with new insights about distinctive explanatory business failure patterns and related financial symptoms.

Bacterial cell division requires the coordinated action of cell division proteins and murein (peptidoglycan) synthases. Interactions involving the essential cell division protein FtsN and murein synthases were studied by affinity chromatography with membrane fraction. The murein synthases PBP1A, PBP1B, and PBP3 had an affinity to immobilized FtsN. FtsN and PBP3, but not PBP1A, showed an affinity to immobilized PBP1B. The direct interaction between FtsN and PBP1B was confirmed by pulldown experiments and surface plasmon resonance. The interaction was also detected by bacterial two-hybrid analysis. FtsN and PBP1B could be cross-linked in intact cells of the wild type and in cells depleted of PBP3 or FtsW. FtsN stimulated the in vitro murein synthesis activities of PBP1B. Thus, FtsN could have a role in controlling or modulating the activity of PBP1B during cell division in Escherichia coli. [less ▲]

The production of essential oil by tissue culture s ol Antbemis nobilis L. including cell suspension, shoot and crown-gall cultures is reported. The biosynthetic capability of these different cultures was compared with that of plants grown in a field. The addition of crude polysaccharide fraction prepared from yeast extract and from the plant itself to shoot cultures affected the composition and total essential content (from 0.08 o/o to 0.3Qo/o dry weight). The essential oil content of the crown-gall tissue ol A. nobilis was 0.25 % of the dry weight and the composition of the essential oil was comparable to that of the flowers. [less ▲]

Wildebeests carry asymptomatically alcelaphine herpesvirus 1 (AlHV-1), a gamma-herpesvirus inducing malignant catarrhal fever (MCF) to several ruminant species (including cattle). This acute and lethal lymphoproliferative disease occurs after a prolonged asymptomatic incubation period after transmission. Our recent findings with the rabbit model indicated that AlHV-1 infection is not productive during MCF. Here, we investigated whether latency establishment could explain this apparent absence of productive infection and sought to determine its role in MCF pathogenesis. First, whole-genome cellular and viral gene expression analyses were performed in lymph nodes of MCF-developing calves. Whereas a severe disruption in cellular genes was observed, only 10% of the entire AlHV-1 genome was expressed, contrasting with the 45% observed during productive infection in vitro. In vivo, the expressed viral genes included the latency-associated nuclear antigen homolog ORF73 but none of the regions known to be essential for productive infection. Next, genomic conformation analyses revealed that AlHV-1 was essentially episomal, further suggesting that MCF might be the consequence of a latent infection rather than abortive lytic infection. This hypothesis was further supported by the high frequencies of infected CD8+ T cells during MCF using immunodetection of ORF73 protein and single-cell RT-PCR approaches. Finally, the role of latency-associated ORF73 was addressed. A lack of ORF73 did not impair initial virus replication in vivo, but it rendered AlHV-1 unable to induce MCF and persist in vivo and conferred protection against a lethal challenge with a WT virus. Together, these findings suggest that a latent infection is essential for MCF induction. [less ▲]
