The significance of sustained entrepreneurial orientation on performance of firms – A longitudinal analysis

This study focuses on the importance of changes in entrepreneurial orientation (EO) over time for subsequent firm performance, and the significance which inimitable resources (networks, governance system and unique competence) might have in this connection. Hypotheses are developed to test the effects that changes in EO level over a time period and resources have on subsequent firm performance. The study is based on data from 168 Norwegian SMEs, interviewed both in 2000 and 2003. The primary contribution of this study is that a change in EO over time (increased or decreased), may be of importance for a firm's performance represented by performance compared to competitors, and employment growth. A focus on entrepreneurial activities seems to be beneficial in the long run (increasing EO), while the opposite is the case if the EO level decreases. It is especially encouraging to see that firms focusing on EO (increased or the same) are positively associated with employment growth, one of the primary policy goals world-wide. Another contribution from this study is that resources that may be inimitable for firms have some influence on performance compared to competitors. Implications for policy-makers, practitioners and further research are discussed.     

Teaching and learning the nature of technical artifacts

Artifacts are probably our most obvious everyday encounter with technology. Therefore, a good understanding of the nature of technical artifacts is a relevant part of technological literacy. In this article we draw from the philosophy of technology to develop a conceptualization of technical artifacts that can be used for educational purposes. Furthermore we report a small exploratory empirical study to see to what extent teachers’ intuitive ideas about artifacts match with the way philosophers write about the nature of artifacts. Finally, we suggest a teaching and learning strategy for improving (student) teachers’ concepts of technical artifacts through practical activities.     

Killing off cohorts: Forecasting mortality of non-extinct cohorts with the penalized composite link model

Mortality forecasting has crucial implications for insurance and pension policies. A large amount of literature has proposed models to forecast mortality using cross-sectional (period) data instead of longitudinal (cohort) data. As a consequence, decisions are generally based on period life tables and summary measures such as period life expectancy, which reflect hypothetical mortality rather than the mortality actually experienced by a cohort. This study introduces a novel method to forecast cohort mortality and the cohort life expectancy of non-extinct cohorts. The intent is to complete the mortality profile of cohorts born up to 1960. The proposed method is based on the penalized composite link model for ungrouping data. The performance of the method is investigated using cohort mortality data retrieved from the Human Mortality Database for England & Wales, Sweden, and Switzerland for male and female populations.     

Slack-adjusted efficiency measures and ranking of efficient units

In non-parametric methods many units are calculated as efficient. The article suggests a method for ranking efficient units, not by their efficiency, but by importance as benchmarks for the inefficient units, in contrast to earlier suggestions in the literature which rank units high if they are specialized. However, the total potentials for improvement frequently remain unrevealed by calculating radial efficiency measures of the Farrell type only. The article therefore first develops efficiency measures that explicitly extend the radial measures to include slacks. The new measures are applied to a typical multidimensional small-sample data set for Norwegian employment offices.     

Ecotour Guide Training in Less Developed Countries: Some Preliminary Research Findings

This paper presents a critical discussion of the internationally prevailing understanding of the concept 'sustainable tourism'. It is argued that the current focus on stationary activities and local, intensive environmental issues is too limited both in relation to the concept of tourism and the concept of sustainable development. There is no tourism without travel. And, as shown in a Norwegian research study, tourist travel is a major source of serious environmental problems. The paper emphasises that sustainable tourism should be linked to a concept of sustainable mobility. However, this mobility would imply not only a change in the means of transport but also a reduced level of mobility in the rich part of the world. As this would entail new forms of tourism, other than those solely based on auto- and aeromobility, it represents a major challenge for the future development of tourism.
