Journal article (peer-reviewed)abstract
- We have investigated the structure of a microbial community in semi-natural sandy grassland in southeast Sweden. The sand is rich in lime, but in most places the soil is decalcified in the upper layers, and therefore this site shows a large variation in pH within short distances. We collected samples at three different soil depths (0-10 cm, 10-20 cm and 20-30 cm) and found the pH to range from 5 to 8 in the topsoil and from 4.5 to 9.5 in the deepest layer. The abundance of saprophytic fungi and bacteria was investigated using signature phospholipid fatty acids and arbuscular mycorrhizal fungi (AMF) using the neutral lipid fatty acid 16:1 omega 5. The PLFA pattern of the topsoil was different from that in the other two layers, as indicated by principal component analysis. The saprotrophic fungi were associated with high pH, and bacteria with low pH in these sandy soils. No relation was found between pH and AMF in the topsoil, while a positive relation was found in the deepest soil layer. The saprophytic fungi-to-bacteria ratio was constant with depth, while the AMF-to-bacteria ratio increased with soil depth. The results showed that high soil pH favoured fungal saprophytes in sandy grasslands and that AMF are relatively more abundant than the other two groups in deeper soil layers: particularly so when the pH is high.

Plant species richness in a natural Argentinian matorral shrub-land correlates negatively with levels of plant phosphorus
- 2011

In: Plant and Soil. - : Springer Science and Business Media LLC. - 0032-079X .- 1573-5036. ; 345:1-2, s. 11-21
-
Journal article (peer-reviewed)abstract
- The aim of this study was to ascertain whether there is a relationship between plant species richness and plant-available N, P and water in an environment subject to little anthropogenic disturbance. To accomplish this we studied the vegetation in matorral shrub-lands in northern Patagonia, Argentina. Due to the variation in slope, precipitation and aspect between the sites water status was determined using the C-12/C-13 fraction, delta C-13, to investigate whether this was a confounding factor. The numbers of herb, shrub, liana and tree species were determined at 20 sites along an estimated precipitation gradient. Leaf P and N content and the delta C-13 of Berberis buxifolia were determined, as well as the soil P and N content at the different sites. A negative correlation was found between species richness and Berberis buxifolia foliar P concentration (52% of the species richness variation was accounted for), and a positive correlation was found between plant species richness and Berberis buxifolia foliar N: P ratios (54% of the species richness variation was accounted for). The relationship between species richness and foliar P was seen when all layers of vegetation were included (trees, lianas, shrubs and herbs). Foliar N showed no correlation with species richness, while soil extractable NH4 showed a weak positive correlation with the number of shrub layer species (lianas, shrubs and trees). The species richness of the shrub layer increased with decreasing values of delta C-13. Low soil P availability thus affects local species richness in the matorral shrub-lands of Patagonia in Argentina although the growth of vegetation in the area has been shown to be limited by N. We suggest that low P levels increase plant species richness because low soil P concentration is associated with a high P partitioning and high potential for niche separation.

And Now Lean : Discursive Practices and their Consequences in Two Organizations
- 2013
-
Conference paper (other academic/artistic)abstract
- How people write and talk about lean, a management concept, has consequences for how we think andact towards lean as a phenomenon in research as well as in practice. It is therefore important to studyhow discourses are used to prioritize specific views and the possible consequences of such use. To thateffect we have studied the implementation of lean in one private and one public organization from adiscursive psychology approach. There is however no consensus about what lean is or about theconsequences its interpretation might bring. Studying the discursive practices that position lean in textand talk it is clear that multiple discourses are used as a flexible resource on different discursive levels(individual text and talk, local discourses of the organization and societal discourses) to make sense ofthe implementation of lean. In this way we contributing to research on lean in a context of managementand organizational research by showing how discourses are deployed in interaction by people in textand talk to perform specific functions such as justify, legitimize, claim and criticize.

Discursive practices in strategic entrepeneurship : discourses and the use of repertoires in two firms
- 2013
-
Doctoral thesis (other academic/artistic)abstract
- This is a thesis in marketing concerned with entrepreneurship in established firms and the discursive practices that take place within a perspective of strategic entrepreneurship. The study of discursive practices in this context assumes a concern with how different aspects of entrepreneurship are produced and consumed by people in text and talk. Strategic entrepreneurship can be seen as an organisational form of entrepreneurship. The latest contribution within strategic entrepreneurship tends to focus on opportunities and advantages in organisations as two processes that need to be considered and managed jointly.In this thesis, I have studied the discursive practices of how scholars position strategic entrepreneurship through an enhanced literature review and by means of a close analysis of assumptions made within strategic entrepreneurship, but also by studying two firms and their discursive practices of constructing opportunity and advantage positions. The results have then been analysed with reference to discourse theory and previous research within entrepreneurship based on European traditions that builds on the linguistic turn.By conducting an empirical study of two firms, I have studied discourses in use, and how they are produced by people. In so doing, two main findings emerge in the discussion of the empirical results: 1) Opportunity and advantage positions emerge in social interaction and are co-constructed. 2) Opportunity and advantage positions are constructed by the use of multiple discourses, on different levels of discourse and for different functions. The main purpose of the thesis is to enhance the understanding of entrepreneurship in established firms and the activities labelled as strategic entrepreneurship. In addressing the purpose, seven theoretical, methodological and empirical contributions to research emerge in areas of strategic entrepreneurship, entrepreneurship and the enterprising self.

Robotdalen Version 2.0 : Challenges and opportunities in the emergence of a new board
- 2014
-
In: IRSPM XVIII Eighteenth Annual Conference of the International Research Society for Public Management (IRSPM). ; , s. 1-28

Conference paper (other academic/artistic)abstract
- Robotdalen - a Swedish robotics initiative with the goal to enable commercial success of new ideas and research - can be defined as a small entrepreneurial hybrid organization that includes private and public organizations. Almost a decade after its creation, Robotdalen is facing new challenges such as the need to balance between the entrepreneurial features that hitherto characterized the organization and the increasingly established and structured governance work practices, routines and procedures. Trying to create this balance has been found, both in research and in practice, to be a major challenge and there has been several calls for research (Ireland & Webb 2007; Kuratko & Audresch 2009; Schindehutte & Morris 2009; Kyrgidou & Huges 2010; Luke et al. 2011; Foss & Lyngsie 2012). There is also a lack of empirical contributions and studies on public organizations in a context of governance, entrepreneurship and strategic matters (Klein 2013).In this paper we ask: How is Robotdalen governed in order to on the one hand create order, structure, predictability and sustainability, while on the other find their own innovative solutions to problems that cannot be standardized or predicted? In this context the governance function of the board becomes important both as the maintainer of what is working in the organization, but also as a developer that renews the organization for future challenges. Therefore, we intend to highlight the performance of governance structures, which so far have been understudied in previous research (Minichilli 2009). There has also been a call for further research on boards in a setting of small organizations (c.f. Minichilli & Hansen 2007; Huse 2008). We intend to meet this call by contributing to the theoretical field of entrepreneurship in established organizations and the field of management governance, i.e. how the board of directors enables, develops and sustains the entrepreneurial spirit an in an inter-organizational relationship (IOR) setting.The findings show the importance to review the composition, role and function of the board when it comes to govern an IOR. Thus, acting in a complex setting of both private and public actors not only poses challenges of monitoring different stakes and interests (cf. Holmgren Caicedo & Mårtensson 2012), but also differences in strategic goals and views on value e.g. public actors put forth values of democracy and accountability, while private actors emphasized values of growth and profitability. In order to achieve this Robotdalen had to take some innovative and entrepreneurial actions in regards to the board’s composition, role and function.To sum it up, in line with suggested research our paper aims to understand governance mechanisms, i.e. structures and processes designed at reconciling the interest of different stakeholders within a board of directors and their governance of IORs. In this sense we relate to the topic of board and organizational outcomes as performance and innovation.

Strategic Entrepreneurship Practices at Robotdalen : A balancing act or Not?
- 2014
-
In: Rencontres de St-Gall, 2014. ; , s. 1-17
-
Conference paper (other academic/artistic)abstract
- In this paper we take an interest in Robotdalen - a Swedish robotics initiative with the goal to enable commercial success of new ideas and research – a small public organization acting in an inter-organizational context of both private and public organizations. By utilizing Robotdalen as a case example we have discussed and analyzed how they during the years have struggled with bureaucratic structures that tend to limit their entrepreneurial work, but also how these structures have been used as an opportunity. The perspective applied to analyze has been a quite new concept of strategic entrepreneurship that takes an interest in both strategy and entrepreneurship as a balancing act in established organizations. The findings suggests that conditions for strategic entrepreneurship practices in inter-organizational contexts is to keep it simple, communicate narratives and being flexible. Moreover, in theory entrepreneurial and strategic processes are considered as dual or the opposite of each other, but our findings rather indicate that they are mutually dependent i.e. they enabling each other’s existence.
