Tidskriftsartikel (refereegranskat)abstract
- Vertical organic electrochemical transistors (OECTs) have been manufactured solely using screenprinting. The OECTs are based on PEDOT:PSS (poly(3,4-ethylenedioxythiophene) doped with poly(styrene sulfonic acid)), which defines the active material for both the transistor channel and the gateelectrode. The resulting vertical OECT devices and circuits exhibit low-voltage operation, relativelyfast switching, small footprint and high manufacturing yield; the last three parameters are explainedby the reliance of the transistor configuration on a robust structure in which the electrolyte verticallybridges the bottom channel and the top gate electrode. Two different architectures of the verticalOECT have been manufactured, characterized and evaluated in parallel throughout this report. Inaddition to the experimental work, SPICE models enabling simulations of standalone OECTs andOECT-based circuits have been developed. Our findings may pave the way for fully integrated, lowvoltageoperating and printed signal processing systems integrated with e.g. printed batteries, solarcells, sensors and communication interfaces. Such technology can then serve a low-cost basetechnology for the internet of things, smart packaging and home diagnostics applications.

Entrepreneurship in Teacher Education - Conceptualization, Design & Learning outcomes
- 2016

Ingår i: RENT XXX, Antwerpen, Belgium, 18-19 November, 2016.

Konferensbidrag (refereegranskat)abstract
- Objectives: Currently some novel initiatives in Sweden aim to introduce entrepreneurship broadly in teacher education programs. The purpose of this paper is to shed light on one of these early attempts. Specifically we will answer the following research questions: How is entrepreneurship conceptualized in teacher education programs? How is the education designed in terms of pedagogy and didactics? What are the main learning outcomes that the education strives for?Literature review: The broadening of the entrepreneurship concept where entrepreneurship is conceptualized as a general method for human development (Sarasvathy & Venkataraman, 2011) as well as the proposition by Hannon (2013) that entrepreneurism is the development of a set of individual behaviors, skills and attitudes can be applied in many societal contexts, has provided openings to work with entrepreneurship in teacher education. However in relation to entrepreneurship education we still lack knowledge on key educational and didactical issues, in terms of for instance the nature and impact of our activities (Fayolle, 2013) and in relation to teacher education programs this knowledge is even more scarce.Approach: In this mainly qualitative case study of a Swedish teacher education entrepreneurship module we apply interviews and surveys of both teachers and students to collect our empirical material. Our starting point is that entrepreneurship education activities in this setting needs to be underpinned by thoughts on theoretical concepts and practices from both entrepreneurship and learning theories. We use Fayolle and Gaillys (2008) teaching model framework as an analytic lens to help provide necessary understanding in relation to our pedagogical and didactical questions.Results: The results show how entrepreneurship education in teacher education is riddled with tensions relating to overall mission, target groups, pedagogy, content and assessments. However, there seem to be viable paths forward that might mitigate these tensions and provide a better opportunity for entrepreneurship education within the realm of teacher education.Implications and Value: First and foremost, we add to the knowledge about how entrepreneurship is introduced in teacher education programs, helping both researchers and practitioners understand the conceptualization, design in terms of pedagogy and didactic, as well as main learning outcomes. By using and building on Fayolle and Gailly’s (2008) theoretical teaching model framework, we provide structured empirical perspectives and knowledge aggregation on pedagogy and didactic in entrepreneurship education. As such we contribute to the knowledge about how entrepreneurship education is operationalized and perceived in a special case of non-business context, from both a teacher and student perspective.

Influences of forest type and habitat structure on bird assemblagesof oak (Quercus spp.) and pine (Pinus spp.) stands in southwesternTurkey
- 2015

Tidskriftsartikel (refereegranskat)abstract
- The Mediterranean basin exhibits a multitude of forest habitats affected by former and current exploitation and management. Recent afforestation programs have resulted in an increase in the proportion of coniferous trees, while oak stands, formerly utilized for coppicing and grazing, are abandoned or converted into coniferous plantations. The loss of oak stands might negatively affect birds dependent upon broadleaved forests. Studies confirming or rejecting that statement are scarce, particularly in the eastern part of the region. Using a study area in southwestern Turkey we applied a guild-based approach to investigate how pine and oak stands across a chronosequence differ in their capacity to support forest bird assemblages. Variables describing the vegetation were sampled to characterize the stands and relate bird assemblages to stand structure. Bird abundance and species richness was positively associated with age for both stand types. Richness and diversity was highest in oak stands, while there were no differences in bird abundance between the two forest types. Pine stands supported a different bird species composition compared to oak stands of the same age. Stand age and structure, rather than forest type, held the highest explanatory powers for bird assembly structure. Primary cavity-nesters and ground-nesters were more abundant in oak stands, possibly reflecting differences in stand structure and resource distribution. To support these birds with suitable habitats, oaks stands need conservation. Management practices in pine stands should strive for increasing the amount of old trees and retain vegetation in the understory to benefit breeding birds.

Research on pedagogical entrepreneurship – a literature review based on studies from Finland, Iceland and Sweden
- 2016
-
Ingår i: Education Inquiry. - : Informa UK Limited. - 2000-4508. ; 7:2, s. 159-182

Tidskriftsartikel (refereegranskat)abstract
- Strategies for entrepreneurship in the educational system are present not only in the Nordic countries, but also in the majority of other Western countries. Linked to these strategies different research efforts have been made. Although the research efforts have a common origin in supranational policies on entrepreneurship, there has been little research analysing the similarities and differences in how the topic is addressed by researchers in different countries. Being able to relate to both the policy and the available research in a nuanced way is important especially in the context of teacher education. The purpose of this article is to review the most recent research in pedagogical entrepreneurship from three countries: Finland, Iceland and Sweden. The aim is to discover whether the common phenomena of entrepreneurship in an educational context are approached differently in these three countries. The review of 21 articles in all, covering aim, method, concepts, references and results, draws a rather fragmented picture of the research. The main results are that the reviewed research was mostly qualitative and covered the entire spectrum from theoretical research to practice-oriented research. A variety of concepts were used. The analysis of the use of references uncovered a need to be more aware of including research from neighbouring regions. The research field seems to be quite lively and is still developing. However, it would benefit from a better dialogue between researchers in order to strengthen the contribution of Nordic research on pedagogical entrepreneurship.

Tidskriftsartikel (refereegranskat)abstract
- PurposeThe purpose of this paper is to present and develop models of educational approaches to entrepreneurship that can provide complementary analytical structures to better study, enact and reflect upon the role of entrepreneurship in higher education.Design/methodology/approachA general framework for entrepreneurship education is developed by using theory as well as practical experiences from the fields of business, engineering and pedagogy. The paper is mainly conceptual where the unfolding Swedish practice is used as contextual backdrop.FindingsThe FOR/IN/THROUGH/ABOUT (FITA) taxonomy is presented and used to develop three models of how to approach entrepreneurship in higher education depending on purpose. As there exists a didactical divide between entrepreneurial education for business and entrepreneurial approach to teaching and learning, educators and researchers ought to let their specific context influence the adoption of the taxonomy as well as the presented models.Research limitations/implicationsThe differentiations suggested by the presented models can be used to both structure the designs and limit claims of future research. More heuristic research is called for.Practical implicationsThe use of FITA in the designing of entrepreneurship education offers new opportunities for enhancing complementary student learning in higher education.Social implicationsThe study suggests that any political or scholarly initiative must acknowledge the diversity of entrepreneurship education and chose different approaches depending on what is to be achieved.Originality/valueThe multidisciplinary approach has made it possible to present and create models that denote a common ground for a productive discussion on how to better understand and make use of entrepreneurship in higher education.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Entreprenöriella kompetenser är viktiga för livslångt lärande, och flera politiska initiativ har tagits för att påverka utbildningssystemet i Sverige och EU. Begrepp som entreprenörskap och entreprenöriellt lärande översätts nu till pedagogiska sammanhang och bildar högaktuella teman i utbildningsdebatten. Det här kapitlet belyser entreprenöriellt lärande samt framväxten av den didaktiska praktik som utvecklas inom utbildning med koppling till entreprenörskap. I beskrivningen skiljer vi på ett snävt synsätt på lärande inriktat mot affärsverksamhet och ett brett synsätt för generellt lärande. Vi presenterar även en taxonomi för att skilja på olika typer av entreprenörskapsutbildningar.

Social Entrepreneurship and Influence on Regional Firm Demography
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The central interest of this thesis is the emergence of social ventures. In this regard, it investigates two types of questions: what regional factors influence the emergence of social ventures? and what types of interaction may emerge between the emergence of social ventures and the demography (entry, exit and migration) of commercial ventures in a region? The thesis also aims to adopt a macro-oriented approach to studying the research questions.To answer those questions, this thesis applies both theoretical and empirical analysis. For the theoretical analysis, instead of a single theory it applies three middle-range theories: theory of organisational ecology, market failure theory, and the demand and supply theory of entrepreneurship. The empirical analysis is based on two large-scale databases from Sweden and the U.S. The Swedish database includes nonprofit social ventures and commercial ventures for the 1990-2014 period from all of the 290 municipalities across Sweden, while the database from U.S. includes 88 counties in the State of Ohio between 2003-2007.The answers to the research questions are presented in the form of six papers. Paper 1 provides an overall picture of the different possible functions of social ventures within communities and their contributions to regional development. With this overall view, Papers 2 and 3 answer the first research question, that is the factors influencing the emergence of social ventures. Thus, while Paper 2 provides a review of previous research, Paper 3 empirically examines some of the regional factors that may influence the emergence of social ventures in a region. The results of Paper 3 revealed that factors such as gender, education, entrepreneurial role models, wealth, unemployment rate, age, and urbanisation positively influence the emergence rate of the of social venture in a region.Papers 4, 5 and 6 are dedicated to answering the second type of research question, in other words the interaction between the emergence of social ventures and the demography (entry, exit and migration) of commercial ventures. As such, Paper 4 studies how the emergence of social ventures is influenced by the entry and exit of commercial ventures, Paper 5 investigates how the emergence of social ventures influences the entry of commercial ixventures, and Paper 6 examines how the emergence of social ventures influences the migration of commercial ventures. In summary, the results of these three papers reveal that while the emergence of social ventures negatively influences the commercial ventures inside a region, it has a positive influence on the commercial ventures outside the region. Paper 6 further investigates the influence of the emergence of commercial ventures on the migration of commercial ventures. The results show that while the emergence of social ventures attracts commercial ventures from outside into a region, the emergence of commercial ventures repels them from moving into the region.

A Silicon-Organic Hybrid Voltage Equalizer for Supercapacitor Balancing
- 2017
-
Ingår i: IEEE Journal on Emerging and Selected Topics in Circuits and Systems. - : IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC. - 2156-3357 .- 2156-3365. ; 7:1, s. 114-122

Tidskriftsartikel (refereegranskat)abstract
- Cell voltage equalizers are an important part in electric energy storage systems comprising series-connected cells, for example, supercapacitors. Hybrid electronics with silicon chips and printed devices enables electronic systems with moderate performance and low cost. This paper presents a silicon-organic hybrid voltage equalizer to balance and protect series-connected supercapacitor cells during charging. Printed organic electrochemical transistors with conducting polymer poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT:PSS) are utilized to bypass excess current when the supercapacitor cells are fully charged to desired voltages. In this study, low-cost silicon microcontrollers (ATtiny85) are programmed to sense voltages across the supercapacitor cells and control the organic electrochemical transistors to bypass charging current when the voltages exceed 1 V. Experimental results show that the hybrid equalizer with the organic electrochemical transistors works in dual-mode, switched-transistor mode or constant-resistor mode, depending on the charging current applied (0.3-100 mA). With the voltage equalizer, capacitors are charged equally regardless of their capacitances. This work demonstrates a low-cost hybrid solution for supercapacitor balancing modules at large-scale packs.

Tidskriftsartikel (refereegranskat)abstract
- A rapidly changing homecare service sector implies difficulties to control safety and health risks for staff and to guarantee standardised deliveries of services to recipients. This study aimed to describe staff perceptions of safety climate and practices in homecare service teams, and suggestions for improvements. A second aim was to identify if and how the appraisals of safety climate were related to individual perceptions of safety, mental strain and adverse events/injury. A convergent parallel mixed methods design was used. Nursing assistants and care aides (133 in total, representing 11 work teams) in the north of Sweden replied to a survey and participated in focus group interviews. Results were analysed with ANOVA (inter-team differences) and by qualitative content analysis. Significant diversity was identified between the teams in five of seven dimensions of safety climate. Important areas for improvement were: a need to define and agree on criteria for a safe working environment; leadership prioritising safety at work; and management able to provide trust, support and time. A prerequisite for these agreements was improved authority and communication between all parties involved. The safety climate dimensions were related to personal perceptions of safety and mental strain and, partly, to adverse events/injuries.

An Entrepreneurial Mindset : Self-Regulating Mechanisms for Goal Attainment
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Comprised of a cover story and five separate but interrelated articles, this dissertation explores entrepreneurial learning. By connecting multiple theoretical perspectives, reviewing extant literature, using four qualitative datasets, and building theory inductively, the articles explain components to and mechanisms of entrepreneurial learning. This dissertation is one of the first to explore the essence of entrepreneurial learning by incorporating non-entrepreneurs and entrepreneurs simultaneously, cognitive processes, and contextual variables. Learning lies at the core of entrepreneurship, and scholars have even argued that a theory of entrepreneurship requires a theory of learning. The literature suggests that experiences in the context of entrepreneurship triggers entrepreneurial learning, and that such learning relates to achieving ambitious goals, the discovery of new opportunities and better overall performance. Entrepreneurial learning has also been highlighted in contexts outside entrepreneurship and as a mean to fostering future entrepreneurs and developing people’s entrepreneurial attributes and characteristics. The idea is that entrepreneurship is a way of thinking and acting and that entrepreneurial learning can be of use to anyone, even to those lacking entrepreneurial experience.Entrepreneurial learning literature, both inside and outside the context of entrepreneurship, emphasizes triggers of entrepreneurial learning, but does not recognize components that enable those triggers to be recognized and acted on and the underlying mechanisms that distinguish entrepreneurial learning from other types of learning. This gap makes it difficult to assess what entrepreneurial learning is and how it can be enhanced for both entrepreneurs and people preparing for entrepreneurship. This dissertation explains how and why entrepreneurial learning can be understood as a simultaneous and active regulation of cognition, motivation, and emotions to achieve goals. This elaboration captures core components and the mechanism of entrepreneurial learning, and illustrates how it can be understood and enhanced in various contexts.

Tidskriftsartikel (refereegranskat)abstract
- Small- and start-up firms in the high-tech industry usually engage in networking to overcome resource, knowledge, and competence constraints in creative, innovation-based competition. Quite often, however, network relationships fail due to lack of network capability (NC), defined as the ability to manage and gain benefits from external relationships. In the present study, we propose and examine an updated five-dimension NC construct and test its effect on innovativeness and performance. Two independent high-tech samples of small firms and start-ups support measurement properties of the proposed NC construct and suggest that the often-overlooked dimension in NC research of network relationship building is important to include in a complete NC construct. Doing so can help explain organizational innovativeness and effects on the customer, sales, and innovation performance more effectively. As a result, we find support for the proposed NC scale and the importance of network capabilities for small companies and start-ups to remain competitive.

Precolonial agricultural terracing in Bokoni, South Africa : Typology and an exploratory excavation
- 2016

-
Tidskriftsartikel (refereegranskat)abstract
- Earlier work on the terraced settlements of the Bokoni area (16th to 19th century, Mpumalanga province, South Africa) focussed on the homesteads, their contents, layout and chronology. This paper suggests a terminology and typology of agrarian structures in Bokoni in order to improve comparative approaches in Africa and beyond. The typology and an excavation of the terracing have made possible preliminary conclusions relevant for the further analysis of the terracing and stone-walling in Bokoni. The terracing developed incrementally, whereby cultivation, stone-clearing and terracing were intermixed processes. This is supported both by the organic content in a section of a terrace and by a phytolith analysis. The phytolith analysis furthermore indicated that maize was cultivated on the terraces, but this should be seen as a pilot study only, and presence of maize in Bokoni must be tested with other archaeobotanical methods.
