Abstract

Purpose

The purpose of this study is to investigate the rheological behaviour of commercial lubrication oils used for cylinder lubrication in two-stroke marine diesel engines. Furthermore, it is of interest to investigate whether the viscosity of lubrication oils is affected by different levels of alkalinity.

Design/methodology/approach

Viscosity measurements are performed using both rotational and capillary rheometry. It was possible to measure oil viscosity in the shear rate from 0.1 to 3,000 s−1 using rotational rheometry, whereas capillary rheometry allowed measurements in higher shear rates from 5 × 105 to 1.3 × 106 s−1 at 50°C.

Findings

The viscosity measurements show that the studied lubrication oils behave as a Newtonian fluid and that the viscosities are insensitive to the level of alkalinity. Furthermore, the viscosity/temperature dependency for the lubrication oils was found to fit the Arrhenius model.

Originality/value

This study presents useful information about the rheological behaviour of lubrication oils, more precisely how the oil properties are affected by shear rate, temperature and level of alkalinity. The value of this research is considered to be important for designing two-stroke diesel engines and cylinder lubrication systems.

Abstract

This chapter focuses upon two types of interaction. One is the interaction between departments within the Danish Trademark and Patent Office (DKPTO). Additionally, the interaction between the DKPTO and firms is analysed. The chapter discusses in what ways an institution like a national patent office is important for product innovation, not just by providing an appropriability system for product innovations in firms, but additionally by improving the long-run capabilities of both firms and the DKPTO itself. The research builds upon interviews in the DKPTO, case stories from firms and of patent granting procedures.

With respect to internal competencies, it is found that no efforts were carried out to create environments for learning between the departments in line with the “learning organizations” described in earlier chapters. However, taking the tasks of the departments into account, the need for such efforts was not obvious. Links to external organizations are not only confined to industrial firms. Many firms, especially the large firms, would not mind if the tasks of the national patent system were moved to the EPO-level. On the other hand, in particular, small, new firms may feel more confident with a national patent office.

Abstract

Purpose

The purpose of this paper is to assess the impact of offshoring and inshoring on the demand for different types of labor.

Design/methodology/approach

The paper uses a survey with 1,500 firms located in the Eastern part of Denmark to identify overall offshoring and inshoring trends. Estimates of the employment impact are founded on data from a sub‐sample of firms with offshoring and/or inshoring.

Findings

The paper shows that in the period 2002‐2005 more jobs were created as a result of inshoring of activities into Eastern Denmark from firms outside Denmark than were eliminated due to offshoring from firms in the Danish region. Overall, highly skilled workers reap the benefits of offshoring and inshoring, whereas the positions of low‐skilled workers are challenged.

Originality/value

In contrast to most academic research on offshoring, which predominantly focus on outward offshoring flows, the study analyzes both outward and inward offshoring (inshoring) and gives a more holistic and balanced view on the magnitude and employment impact.

Abstract

Purpose – The purpose of the chapter is to analyze the factors that lead firms to offshore advanced tasks.

Methodology/approach – The study uses a 1,500-firm survey from Denmark to investigate the offshoring of 12 tradable manufacturing, technical, and service activities across different industries.

Findings – Findings indicate that offshoring of advanced tasks is driven by a different set of strategic motives than previous waves of offshoring, which predominantly included simple and standardized routine tasks. While the lower cost of unskilled, labor-intensive processes is the incentive for firms that offshore less advanced tasks, a desire to broaden and deepen global networks of new knowledge spurs highly knowledge-intensive companies to offshore more advanced tasks.

Originality/value of chapter – We propose that offshoring should be analyzed on a more disaggregated level of analysis than is the norm in mainstream offshoring literature. To reflect the trend whereby firms are “slicing” their value chain in finer and finer parts and locate these in various locations around the world, offshoring should be analyzed at the task level, since this paves the way for a richer understanding of offshoring strategies and processes.

Abstract

Purpose

While mainstream theories in international business and management are foundedeither explicitly or implicitly on studies of manufacturing firms, prior attempts to develop theoryon the internationalization of service firms are sparse and have yet to establish solid andcomprehensive frameworks. The thrust of this study is that value creation logics, a constructoriginally developed by Stabell and Fjeldstad (1998) can assist us in better understanding why and how service firms internationalize. The authors extend this construct and propose that the internationalization of service firms must be based on a thorough understanding of the fundamental nature of these firms.

Design/methodology/approach

Theoretical study.

Findings

The authors put forward propositions concerning the pace of internationalization and the default foreign operation modes in service firms.

Research limitations/implications

The use of value creation logics can be a useful complement to the conventional approaches to the study of service firms’ internationalization. However, the fact that most firms encompass more than one value creation logic complicates the use of firm databases and industry statistics.

Practical implications

The authors suggest that managers in service firms should consider primarily the nature of the value creation logic(s) in their firms when deciding and designing an internationalization strategy.

Originality/value

The study presents a novel theoretical approach and a set of propositions on service firm internationalization founded on the specific characteristics of the service activities.

Abstract

Purpose

The purpose of this paper is to examine how essential dimensions of customer experience management (CEM) drive business performance in Danish companies.

Design/methodology/approach

An empirical study is conducted to investigate the relationships between seven CEM dimensions, differentiation, market performance and financial performance. The conceptual model is operationalized by a structural equation model, and the model is estimated and tested by using the partial least squares method. A survey among 484 companies in Denmark forms the empirical basis for the study.

Findings

The findings provide evidence that the seven CEM dimensions influence differentiation, market performance and financial performance. High-performing companies differ significantly from low-performing companies with regard to how they master the CEM, meaning that those companies which incorporate superior customer experience into their products and service enjoy measurable financial success.

Research limitations/implications

This study is limited to the seven identified CEM dimensions in Danish companies.

Practical implications

This study has clear implications in terms of identifying and measuring the importance of essential CEM dimensions which influence business performance. The results can help companies to understand CEM and develop CEM strategies.

Originality/value

The paper provides a deeper insight into CEM and how CEM works.

Abstract

Purpose

This paper aims to examine the impact of board governance quality (BGQ) and its mechanisms, namely board activity, board independence, board communication and board expertise, on the level of risk disclosure compliance (RDC) among financial institutions (FIs) in Uganda.

Design/methodology/approach

The study adopts a cross-sectional design where data are collected through a questionnaire survey and audited financial statements of 83 FIs. The authors employ partial least square structural equation modeling (SmartPLS32.7) to test hypotheses.

Findings

The authors find that the level of RDC in Ugandan FIs is low. Further, the study finds the positive relation between BGQ and RDC. Moreover, the authors find that RDC is positively and significantly related with board activity, board independence, board communication and board expertise. Furthermore, the authors find that the level of RDC is positively and significantly related to ownership type, firm size and board size, respectively. Nevertheless, industry type, number of branches and firm age are insignificantly related to RDC.

Practical implications

The study provides relevant insights into regulators and policy makers with early symptoms of potential problems regarding weak board governance in FIs. Policy makers may also use these findings as a guideline tool for improving existing board governance frameworks in place and development of new disclosure policies. In addition, the study provides an input into the review and amendments of existing corporate governance codes for the regulators.

Originality/value

This study offers the empirical evidence on the nexus between BGQ and RDC of FIs in Uganda. Moreover, the study also offers evidence on how BGQ mechanisms impact RDC. The study also further adds theoretical foundations to the RDC literature.
