23rd Nordic Workshop on Bibliometrics and Research Policy 2018 Book of abstracts
- 2018
-
Editorial proceedings (other academic/artistic)abstract
- Initiated by Professors Olle Persson and Peter Ingwersen, bibliometric researchers in the Nordic countries have arranged annual Nordic workshops on bibliometrics since 1996. The general scope of the Nordic Workshop on Bibliometrics and Research Policy is to present recent bibliometric research in the Nordic countries, to create better linkages between the bibliometric research groups and their PhD students, and to link bibliometric research with research policy.The workshop language is English and the workshop is open to participants from any nation. The 23rd Nordic Workshop on Bibliometrics and Research Policy (NWB’2018) was organized by the Swedish School of Library and Information Science (SSLIS) at University of Borås, Sweden. It was held at University of Borås, on November 7-9th, 2018 with 100 participants.In total, we received 35 submissions. After reviewing the submissions, the program committee decided which papers were to be presented orally and which as poster presentations. 21 papers were accepted as oral presentations. These, as well as the titles of the two invited keynote talks and the abstracts of 9 posters, are presented as abstracts in these proceedings. The posters and oral presentation slides are also available for viewing and peer-feedback at figshare (with citable DOIs):https://doi.orgWe would like to thank all authors for their submissions, the session chairs and the keynote speakers, Fredrik Åström and Merle Jacob, for their contributions to the workshop and the student volunteers, for their diligent efforts during the workshop. Further, we would like to thank the sponsors for their generous financial support, without which the Nordic workshops could not be organised in their current form.The NWB’2017 website is at https://hb.se/nwb2018Follow on twitter as @nwb_2018 and #nwb2018

31 recommendations for increased profit - reducing waste
- 2010
-
Reports (other academic/artistic)abstract
- Those companies and organizations that wish to ensure long-term profitability must successively decrease resource use in both product development and in product usage. Primarily, it is waste that must be reduced, i.e. the consumption of resources that do not add to customer value or to the organization. Waste is widespread in all operations. Even in well-functioning processes, more than half of the resource consumption can be classified as waste. One obstacle to waste elimination is that most waste is hidden. Thus, executives, middle management and specialists must prioritize efforts to uncover the waste in their operations.Building and construction activities consist of a complex system of decisions, components, organizations and processes that must be coordinated. There are therefore many explanations as to why waste arises, or does not. Based on a series of discussions with experienced builders, consultants, contractors and materials providers, five main groups of factors that characterize effective operations were found. In this report these factors are illustrated in the form of a “value pyramid”. A holistic view of long-term customer benefits is the apex of the pyramid. Structure, competence, leadership and culture act as the driving forces at each corner of the pyramid’s foundation. Should one of the corners gives way, then the pyramid risks toppling over.With the value pyramid as support, 31 recommendations for what should be done to reduce waste are presented. These are aimed at standardizing the product from an overall perspective (five recommendations), defining and standardizing processes (ten recommendations), developing the organization and its competence (seven recommendations), disciplining management (five recommendations), and driving continuous improvement work (four recommendations). Reducing uncertainties and increasing effective time utilization are the red threads, as the Swedes would say, that run through all the recommendations.Everyone who uses resources has a responsibility to reduce waste. By systematically monitoring one’s own use of time, one can gain insights that will help improve one’s work situation. However, the burden of initiating and driving improvements overall obviously lies with management. How this should be done depends on the nature and purpose of the activities as well as on the organization’s capabilities. It is to manage this progress and achieve profitability that managers are appointed. It is in the interest of all enterprises and organizations to develop the ability and an interest to detect and understand what work/task is value adding what is not. This ability will provide possibilities to develop new competitive advantages and new business concepts.

Smart energy monitoring and power quality performance based evaluation of 100-kW grid tied PV system
- 2023
-
In: Heliyon. - 2405-8440. ; 9:6
-
Journal article (peer-reviewed)abstract
- Globally, the demand for energy from renewable sources is growing due to the increasing electricity consumption and the pollution of fossil fuels. The government has framed various policies to facilitate green energy generation, encouraging renewable energy source usage through PV installations in multiple sectors, including educational institutions. The primary objective of this paper is to propose a methodological approach for analysing the performance of the installed PV system on the rooftop of a university building in Tamil Nadu, India. The site selected is favourable for electricity generation from PV systems with an average global solar radiation of 5.82 kWh/m2day. Solar energy changes periodically with annual and daily variations and is not steady due to seasonal changes. The step-by-step performance assessment and the annual performance of the 100-kW solar PV system, which was instituted in 2019, with the forecasted parameters, are presented in this paper. Therefore, the assessment analysis is carried out in four phases: feasibility assessment, Energy yield assessment, Life cycle assessment, and Power quality assessment. To improve the solar PV output and efficiency, considering the solar irradiation, temperature, wind velocity, etc., PV yield is measured to evaluate the PV system's energy metrics. This paper also considers the carbon credits earned, solar power generated in the location, and the payback period. The power quality assessment is carried out in this paper to test the PV plant's compliance with effective grid integration.

Using X-chromosomal markers in relationship testing: Calculation of likelihood ratios taking both linkage and linkage disequilibrium into account
- 2011
-
In: Forensic Science International: Genetics. - : Elsevier BV. - 1872-4973 .- 1878-0326. ; 5:5, s. 506-511
-
Journal article (peer-reviewed)abstract
- X-chromosomal markers in forensic genetics have become more widely used during recent years, particularly for relationship testing. Linkage and linkage disequilibrium (LD) must typically be accounted for when using close X-chromosomal markers. Thus, when producing the weight-of-evidence, given by a DNA-analysis with markers that are linked, the normally used product rule is invalid. Here we present an implementation of an efficient model for calculating likelihood ratios (LRs) with markers on the X-chromosome which are linked and in LD. Furthermore, the model was applied on several cases based on data from the eight X-chromosomal loci included in the Mentype® Argus X-8 (Biotype). Using a simulation approach we showed that the use of X-chromosome data can offer valuable information for choosing between the alternatives in each of the cases we studied, and that the LR can be high in several cases. We demonstrated that when linkage and LD were disregarded, as opposed to taken into account, the difference in calculated LRs could be considerable. When these differences were large, the estimated haplotype frequencies often had a strong impact and we present a method to estimate haplotype frequencies. Our conclusion is that linkage and LD should be accounted for when using the tested set of markers, and the used model is an efficient way of doing so.

A TDD Distributed MIMO Testbed Using a 1-bit Radio-Over-Fiber Fronthaul Architecture
- 2024
-
In: IEEE Transactions on Microwave Theory and Techniques. - 0018-9480 .- 1557-9670. ; In Press
-
Journal article (peer-reviewed)abstract
- We present the uplink and downlink of a time-division duplex distributed multiple-input multiple-output (D-MIMO) testbed, based on a 1-bit radio-over-fiber architecture, which is low cost and scalable. The proposed architecture involves a central unit (CU) that is equipped with 1-bit digital-to-analog and analog-to-digital converters, operating at 10 GS/s. The CU is connected to multiple single-antenna remote radio heads (RRHs) via optical fibers, over which a binary radio frequency (RF) waveform is transmitted. In the uplink, a binary RF waveform is generated at the RRHs by a comparator, whose inputs are the received RF signal and a suitably designed dither signal. In the downlink, a binary RF waveform is generated at the CU via bandpass sigma-delta modulation. Our measurement results show that low error-vector magnitude (EVM) can be achieved in both the uplink and the downlink, despite 1-bit sampling at the CU. Specifically, for point-to-point over-cable transmission between a single user equipment (UE) and a CU equipped with a single RRH, we report, for a 10-MBd signal using single-carrier (SC) 16 quadratic-amplitude modulation (QAM) modulation, an EVM of 3.3% in the downlink, and of 4.5% in the uplink. We then consider a CU connected to three RRHs serving over the air two UEs, and show that, after over-the-air reciprocity calibration, a downlink zero-forcing precoder designed on the basis of uplink channel estimates at the CU achieves an EVM of 6.4% and 10.9% at UE 1 and UE 2, respectively. Finally, we investigate the ability of the proposed architecture to support orthogonal frequency-division multiplexing (OFDM) waveforms, and its robustness against both in-band and out-of-band interference.

Distributed Massive MIMO via all-Digital Radio Over Fiber
- 2020
-
In: Conference Record - Asilomar Conference on Signals, Systems and Computers. - 1058-6393. ; 2020-November, s. 319-323
-
Conference paper (peer-reviewed)abstract
- A crucial challenge in the implementation of distributed massive multiple-input multiple-output (MIMO) architectures is to provide phase coherence while, at the same time, limit the complexity of the remote-radio heads (RRHs), which is important for cost-efficient scalability. To address this challenge, we present in this paper a phase-coherent distributed MIMO architecture, based on off-the-shelf, low-cost components. In the proposed architecture, up- and down-conversion are carried out at the central unit (CU). The RRHs are connected to the CU by means of optical fibers carrying oversampled radio-frequency (RF) 1-bit signals. In the downlink, the 1-bit signal is generated via sigma-delta modulation. At the RRH, the RF signal is recovered from the 1-bit signal through a bandpass filter and a power amplifier, and then fed to an antenna. In the uplink, the 1-bit signal is generated by a comparator whose inputs are the low-noise-amplified received RF signal and a suitably designed dither signal. The performance of the proposed architecture is evaluated with satisfactory results both via simulation and measurements from a testbed.

Capturing processes in longitudinal multiple case studies
- 2012
-
In: Industrial Marketing Management. - : Elsevier BV. - 0019-8501. ; 41:2, s. 235-246
-
Journal article (peer-reviewed)abstract
- This paper discusses and suggests a methodological approach to capture processes in multiple case studies. While single case studies may address processes in an inductive or abductive manner, multiple case studies entail a stronger need for analytical frameworks and methodological tools developed ex ante in order to maintain focus on the same phenomena across cases and over time. This is, however, difficult to pursue in studies that focus on processes. The aim of the paper is to suggest an approach to longitudinal multiple case studies. We use an example of an on-going multiple case study aiming at capturing the processes of strategizing in terms of how the networking of start-up companies interplays with their ideas of future network positions. The paper concludes by suggesting the use of a combination of narratives and network drawings. Network drawings can be instrumental in capturing the past, the present and the future at different points in time for the individual cases. Based on these descriptions, change patterns and how these evolve can be analyzed and compared across cases and over time.

Designing and Assessing Learning in Venture Creation Programs - Winner of Best Practitioner Development Workshop Award
- 2018
-
Conference paper (other academic/artistic)abstract
- Workshop Summary In Venture Creation Programs the venture acts as a ‘learning vessel’, enabling what students need to learn - and more - given a greater or lesser extent of guidance. But how do we ensure that the students are engaging in ‘doing what they need to do’ in order to ‘learn what they need to learn’? In this workshop, participants will benchmark and crowdsource to identify and develop teaching tool prototypes for venture creation programs. Each ‘teaching tool’ consist of a learning objective, a combination of learning activities and an assessment suggestion. The workshop consists of two steps: the first is to capture learning activities from the entire group; then we divide into smaller groups where we develop them further into teaching tools. The teaching tools can later be used by the participants in their home university in order to package integrated venture activities so that the activities become aligned to the learning objectives.

Explaining incubators using firm analogy
- 2009
-
In: Technovation. - : Elsevier BV. - 0166-4972. ; 29:10, s. 657-670
-
Journal article (peer-reviewed)abstract
- Incubators are initiated to accelerate the development of new technology-based firms. Policy actors see them as a tool to initiate or revive innovativeness in regions and universities as a way to commercialize research results. However, even though the intended results of the incubator are good it is not known how the incubator should be managed and organized in order to achieve this end. When faced with a new type of organizations analogies can provide insights gathered from other contexts. To contribute to the further understanding of incubators this paper discuss the implications, in terms of highlighted dimensions and further clarifications needed when using the analogy of a firm. The paper uses empirical findings from six incubators. The discussion shows it is not clear who is the actual customer of the incubator. For example, can the policy actors that provide the funding to the incubator be seen as a customer paying for the service of regional revival and the NTBFs customers when their fees are not in relation to the services they are provided? In the discussion it is suggested that the incubator can have many customers with different value creation processes or no customers depending on the viewpoint taken.

Exploring the roles of university spin-offs in business networks
- 2016
-
In: Industrial Marketing Management. - : Elsevier BV. - 0019-8501 .- 1873-2062. ; 59, s. 157-166
-
Journal article (peer-reviewed)abstract
- This paper identifies different university spin-off (USO) roles related to resource interaction among business parties. It does so by mapping how USOs become part of business networks in terms of their roles relative to other parties. The theoretical frame of reference focuses on roles and resource interaction based on an industrial network approach to business markets. The empirical research is based on five cases of USOs representing a variety in terms of technology, degree of newness, sector, and area of application. As a result of the analysis, three different roles are identified: the USO as resource mediator, resource re-combiner and resource renewer. These roles reflect how USOs adapt resources to, or require changes among, business parties' resources. The paper also discusses the main resource interfaces associated with the three roles and related challenges. The paper contributes to previous research through illustrating USOs' roles relative to business parties from a resource interaction point of view, and by pointing to the establishment of new companies in business networks as a way of implementing innovation. Finally, the paper discusses the managerial implications of the research in terms of the USO's need to understand which role to take and how to develop it.

Incubator performance : An efficiency frontier analysis
- 2008
-
In: International Journal of Business Innovation and Research. - 1751-0252 .- 1751-0260. ; 2:4, s. 354-380
-
Journal article (peer-reviewed)abstract
- Assessments and evaluations of incubators has been a topic of discussion for as long as incubators have been in existence due to the fact that there has not been an agreement on how to determine good performance. This paper demonstrates the use of Data Envelopment Analysis (DEA) when studying performance of incubators. More specifically, it does so within the four dimensions of cooperation with universities, business networks, external funding and competence development on a sample of 16 Swedish incubators. We show that DEA enables us to measure non-numerical dimensions, and to simultaneously take into account the efforts made by both the incubator and the outcomes. Moreover, DEA provides benchmarks and, based on a model that divides the incubators into four different groups, illustrates the difference between the benchmark and the incubators' current situation.

Incubators and incubation -Resources and activities in relation to different actors
- 2008
-
Doctoral thesis (other academic/artistic)abstract
- ABSTRACTIncubators prepare new technology-based firms (NTBFs) for the obstacles ahead, they complement and develop the entrepreneurial ability of the firm founder, advise regarding financing, as well as providing structure and credibility to the firm. Incubators accelerate the development of the firms towards growth, create an entrepreneurial and innovative climate in the region, and contribute to the commercialization of research results from the university. There are many descriptions but still there remains the difficulty of understanding what an incubator is, and what it does. There is a great difference between incubators due to them having been formed in relation to different actors who have varying histories. Based on the appended papers the principal actors in relation to incubators are: the incubator, the NTBFs, the university, the policy actors and the financial actors. Moreover, the part played by the incubator differs depending on the roles in relation to the different actors, and they often have more than one role in relation to the same actor. Hence, the purpose of this thesis is to explore incubation in relation to different actors. The exploration includes five appended papers. Three of the papers focus on the role of the incubators when helping the NTBFs find and utilize resources. The three types of resources are knowledge, financing and relationships. The two remaining papers focus on the incubator as an organization with particular interest in value creation and efficiency. All five appended papers are written using the resource-based view. In the cover paper the findings in the appended papers are reflected upon using the industrial network approach in order to provide another perspective, focusing on relationships as opportunities leading to an understanding of incubators and incubation. In the cover paper principal actors, activities and resources are explored. The NTBFs are developed through the incubation with the help of resources contributed by the other actors. Additional to the development, the cover paper discussed other activities included in the incubation, i.e. mediation, innovation and acceleration. These activities enable actors to access and combine resources, within and across firm boundaries, that they would otherwise have difficulties combining at that point in time, as quickly or in that way. The relationships of the incubator enable mediation of contacts between actors who are otherwise reluctant to collaborate. Through these collaborations new resource combinations may be found. Resource combinations in already existing relationship can be found using experience from other relationships. In other words, the relationships of the incubator contribute to innovation among the actors. Furthermore, the relationships of the incubator contribute to the acceleration of the NTBFs’ development by being a trusted third party actor, and by contributing to the coordination of actors aiming at improving the innovative climate. Hence, relationships are a special kind of resource for the incubators. The importance of the relationships for the incubators implies that the critical issues might not be to pick NTBFs based on criteria for growth potential, but rather on the ability to form and develop relationships for themselves, as well as the NTBF, in order to develop the firm. Furthermore, arguments regarding the increasing homogeneity among Swedish incubators are based on the rather formalized relationships with the policy actors where incubators tend to play rather similar roles. The heterogeneity is likely to be perceived as larger from the perspective of relationships that are more context specific. Moreover, the relationships, activities and combination of resources cross-fertilize each other without a natural or manageable direction that cannot be controlled by one or a few of the actors involved. After the concluding discussion there is a retrospection of the development of the thesis and the empirical material, which is based on qualitative and quantitative data that has been gathered within the Swedish incubator program mainly during 1999, 2005 and 2006.

Incubators and new technology-based firms - A resource-based view of development
- 2006
-
Licentiate thesis (other academic/artistic)abstract
- New technology-based firms (NTBFs) are based upon the exploitation of a new technology. This often means that there are few other than the founder who understands the technology, and in addition the firm often aims at serving a market in a new way or operating on a presently non-existent one. Therefore, it can be hard to determine the future potential of NTBFs, and this causes growth constraints on the firm. However, the NTBFs that do survive contribute to industrial and regional growth on a long-term perspective through, for example, knowledge spillovers as well as finding and developing product concepts. The incubator on the other hand can be seen as a provider or mediator accelerating the development of promising NTBFs. As a provider the incubator mobilizes resources and adjusts them to the needs of the particular NTBF. The mediator role can instead be seen when the incubator connects the NTBF to members of the incubators external network.The basis of the resource-based view is that a competitive advantage comes from the heterogeneity in terms of resources between firms. Imitability of valuable resources makes the competitive advantage sustainable. The newness of the NTBFs implies that they are in the process of trying to obtain or develop their resources. These resources include capabilities that determine how well the organization is able to perform a certain task. Furthermore, resources like funding, patenting, human resources and intangible resources are needed. Similarly, the incubator benefits from knowledge workers, funding and continuous improvements of the knowledge base in order to serve the NTBFs and maintain fruitful external relations. Consequently, this thesis has the purpose of exploring how the obtaining of resources link incubators and NTBFs. This exploration includes three papers in which the first two are devoted to the incubator, and the NTBFs respectively, in order to understand the resource needs of these two types of organizations. However, the third paper focuses on the links between the incubator and the NTBF in terms of providing links to external actors. Further, the exploration includes empirical findings from both qualitative and quantitative data that have been gathered within the Swedish incubator program during 1999 and 2005. The concluding discussion suggests that the human and knowledge resources of the incubator increase the external resources and the capabilities of the NTBFs. A successful NTBF in turn improves the human and knowledge resources of the incubator through knowledge sharing and an increased reputation. An increased survival rate of NTBFs will also positively affect the public funding of the incubator. It is in this way that a positive spiral is created where the resources of the incubator accumulate as more and more successful NTBFs are generated. Failing NTBFs will, on the other hand, also make it more difficult for the incubator to obtain and maintain resources. Seeing the connections between incubators and NTBFs in this way further emphasizes the element of path dependency in the development of these organizations. Subsequently, there is also a long-term aspect of the expected results on regions and industries from public investments made in them.

Nourishment for the piggy bank : facilitation of external financing in incubators
- 2011
-
In: International Journal of Technology Transfer and Commercialisation. - : Inderscience. - 1470-6075 .- 1741-5284. ; 10 3-4, s. 354-374
-
Journal article (peer-reviewed)abstract
- In this paper, we argue that incubators facilitate access to external financing for their incubatees. Incubators use a wide range of activities to facilitate the accessing of external financing from public and private sources. We have grouped these into two sets of activities. The general activities aim to develop the conditions for external financing through information, education of incubatees, network-building and lobbying activities. The specific activities aim to assist the individual incubatee in their pursuit of external finance through help in application procedures, establishing need for capital, making contacts with the best public or private investor, etc. Based on the survey data, we have also shown that it is more common for incubatees to attract external capital compared to non-incubator firms. The incubatees seem especially successful in attracting public capital. The incubatees also attract more private external capital, however, the observed frequency of private capital in the incubatees are low.

Relationship development patterns of university-based start-ups
- 2021
-
In: A Research Agenda for the Entrepreneurial University. ; , s. 207-228
-
Book chapter (other academic/artistic)abstract
- In the present chapter, we focus on how start-ups become embedded in the university and industry context(s) in order to suggest a research agenda for a more systemic approach to university and industry actors when studying start-up development in entrepreneurial universities. More specifically, the story should not end in business formation but an entrepreneurial university also has roles in the further development of start-ups originating both from the university and industry. We base our suggested research agenda on a case study of the automotive and transport cluster in Western Sweden, which is established as both an academic context and an industry context. We relied both on secondary data about the case as such as well as primary data about the relationship development patterns of the 9 start-ups in the cluster. We identified 5 different patterns of how start-ups become embedded. Arguing that the development and success of university-based start-ups have to be understood in terms of how they embed in their context(s) entails several important implications for further studies connected to additional details of the development patterns, the roles universities play in the networking and embedding of start-ups and the design of collaborative platforms for collaboration between various actors.

Technology Transfer Offices, Incubators, and Intellectual Property Management
- 2016
-
In: 76th Annual Meeting of the Academy of Management.
-
Conference paper (peer-reviewed)abstract
- In this paper we present a systematic literature review of the intersection between intellectual property (IP) management, technology transfer offices (TTOs) and incubators (and to some degree also science parks) in order to find out how incubators and/or TTOs support and work with patenting and IP management in startups. IP management is an important issue for the competitiveness of technology based startups and a difficult issue due to the resources needed to obtain, monitor and enforce IP rights. Understanding how the support organizations facilitate this work is therefore of importance for the startups as well as for universities and policy actors seeking to support technology transfer. The identified publications were systematized according to the actor in focus and whether the paper discussed IP as an output or as a strategic focus. The literature review showed that this literature tends to adopt a simplistic view of IP management, not taking all strategies into account. The literature typically narrows the focus down to a simplistic view of trying to increase the patent output of TTOs and incubators, and the related firms and/or universities.

Levelling the playing field: Could entrepreneurship education compensate the lack of entrepreneurial pedigree and prior experience?
- 2022
-
Conference paper (other academic/artistic)abstract
- Questions we care about: In the last four decades, the importance of entrepreneurship education for societal renewal has seen a dramatic rise. Policy arguments state that to spur economic development, a more entrepreneurially oriented workforce is needed. To increase our understanding of how entrepreneurship education impacts entrepreneurial careers, the purpose of this paper is to investigate how entrepreneurship education, in the form of venture creation programs (VCPs), mitigate or surpass a lack of entrepreneurial career antecedents, such as entrepreneurial pedigree or prior entrepreneurial experience. We ask: What role do VCPs play in the subsequent career choice of graduates regarding career impact relative to prior entrepreneurial experience and entrepreneurial pedigree? Approach: This paper investigates the role of VCPs, entrepreneurial pedigree, and prior entrepreneurial experience regarding early career choice. A broad perspective of entrepreneurial career is considered, across four occupational forms: self-employed, entrepreneurial employment (intrapreneur), hybrid (self-employed and employed in parallel), and conventional employment. To investigate career choice, data from graduates of VCPs at three universities in Northern Europe was collected through an online survey. Questions addressed graduate background prior to education, yearly occupational employment subsequent to graduation, and graduates’ own perception of entrepreneurial activity in employment positions. The survey was sent to 1326 graduates (total graduate population = 1568) and received 692 responses (52.2% response rate). Results: The educational context of VCPs, whether Ind-VCP or Corp-VCP, mitigated prior entrepreneurial experience. Although prior entrepreneurial experience interacted with Ind-VCP in making a career as self-employed more likely, this was not the case for Corp-VCP, in subsequently choosing intrapreneurial careers. Entrepreneurial pedigree had no significant effect on career choice other than for hybrid careers. Implications: Entrepreneurial experience gained from VCPs seems to influence graduates towards future entrepreneurial careers. For some, a VCP is the first entrepreneurial experience, while others are building existing entrepreneurial experiences. Evidence supports the conclusion that many VCP graduates lacking prior entrepreneurial experience instead develop entrepreneurial competencies (knowledge, skills, and judgmental abilities) through the program, which prepares them to engage in subsequent entrepreneurial careers. For policy and practice, entrepreneurship education can level the playing field for students aspiring to an entrepreneurial career but lacking prior entrepreneurial experience or entrepreneurial pedigree. This is an important insight when considering the need to spur innovativeness among businesses transitioning towards sustainable futures and/or recouping from the economic downturns created and perpetuated by the pandemic. Our evidence illustrates that action-based, contextualized education in entrepreneurship creates graduates that engage either as self-employed or as change agents (working with initiating and developing new opportunities) in established businesses. Value/Originality: This study offers novel evidence that entrepreneurship education can level the playing field for students preparing for entrepreneurial careers but lacking prior entrepreneurial experience or an entrepreneurial pedigree.

Journal article (peer-reviewed)abstract
- Purpose : To increase the understanding of how entrepreneurship education impacts entrepreneurial careers, the purpose of the paper is to investigate the role that a venture creation program (VCP) might have in mitigating or surpassing a lack of other antecedents of entrepreneurial careers. In particular, the authors focus on entrepreneurial pedigree and prior entrepreneurial experience. Design/methodology/approach : Data from graduates of VCPs at three universities in Northern Europe were collected through an online survey. Questions addressed graduate background prior to education, yearly occupational employment subsequent to graduation and graduates' own perceptions of entrepreneurial activity in employment positions. The survey was sent to 1,326 graduates and received 692 responses (52.2% response rate). Findings : The type of VCP, either independent (Ind-VCP) or corporate venture creation (Corp-VCP), influenced the mitigation of prior entrepreneurial experience. Prior entrepreneurial experience, together with Ind-VCP, made a career as self-employed more likely. However, this was not the case for Corp-VCP in subsequently choosing intrapreneurial careers. Entrepreneurial pedigree had no significant effect on career choice other than for hybrid careers. Research limitations/implications : Entrepreneurial experience gained from VCPs seems to influence graduates toward future entrepreneurial careers. Evidence supports the conclusion that many VCP graduates who lack prior entrepreneurial experience or entrepreneurial pedigree can develop sufficient entrepreneurial competencies through the program. Originality/value : This study offers novel evidence that entrepreneurship education can compensate for a lack of prior entrepreneurial experience and exposure for students preparing for entrepreneurial careers.

The gender gap in entrepreneurship: The role of the relative pay off from entrepreneurship
- 2022

In: RENT Proceedings. - 2219-5572. ; 2022

Conference paper (peer-reviewed)abstract
- Objectives Entrepreneurship education garners increasing interest, with current trends showing a greater number of women applying. However, less is known about how attendees experience the use of their education post-education in general, in regard to the relative pay-off in graduates’ subsequent careers. Similarly, the extent to which applied entrepreneurial competencies gained may differentiate in careers of women compared to men is also understudied. Research on the distinct gender populations, focusing on occupational differences have limited space in literature. The objective of this paper is to investigate the career metrics in income and work-life balance, comparing and contrasting a population of entrepreneurship education graduates, along gender lines. Literature review Literature points an underlying gender bias in entrepreneurship, where opportunity-based entrepreneurial careers and self-concept of an entrepreneur has predominantly been studied from a male perspective. For example, studies have highlighted aspects of gender bias towards women engaging in opportunity-based entrepreneurship such as difficulty in obtaining necessary funding for growth, challenges in accessing entrepreneurial networks, lower levels of self-belief and self-efficacy regarding entrepreneurial activity, differences in education, and imbalance in work expectations relative to home life. However, these studies have predominantly focused on a new firm formation definition of entrepreneurship. The utilization of entrepreneurial competencies, as developed through entrepreneurship education that focuses on experience- and reflection-based approaches to learning, have in recent studies shown to be equally important for intrapreneurs as self-employed entrepreneurs. This reflects the broader contextual spread of applied entrepreneurial competence in graduate careers. The entrepreneurial careers of the female graduates who engage in ideation and implementation of new business activity after an entrepreneurship education, may it be in firm formation or in employed roles, remains understudied. Therefore, the question is raised: What is the relative pay-off (i.e., income and work-life balance) of entrepreneurship in relation to occupational choice and gender for graduates of entrepreneurship educations? Approach/Method Alumni from three master-level venture creation programs at three universities in Northern Europe were contacted for this study. From a total population of 1103 (graduating between 1997-2018),531 graduates responded, resulting in a response rate of 48.1 percent. The gender distribution in the total population is 28.5 percent female, and within the respondent sample it is 29.5 percent female. Two dimensions of career progress: income and work-life balance, was then analyzed with a set of dependent variables and control variables in ordinal regression. These regressors include career start-up experience and to what extent ideation and implementation of new business activity in employed occupations impacts the independent variables. Models are based on separate regressions on men and women with the purpose to highlight gendered differences in career progression and what regressors contributes to this. Results/Findings The findings were divided into separate sets by the two dependent variables, income and work-life balance. For income levels, career length is shared by both men and women as being a strong predictor. Beyond that, the regression analysis gives different versions for women and men of what contributes to a high income. Men in paid employment (as conventional employees or intrapreneurs) earns more than their self-employed and hybrid (combining employment and self-employment) peers. For women, there is no significant differences among the occupations. For both genders, type of industry is also influential towards the income level. Work-life balance generated regressions that points towards small influences of the regressors for women. For men, having a partner indicates a higher work-life balance, which is not significant for women. Also, having less work related to entrepreneurial competencies (i.e., being conventional employed), results in a more positive work-life balance. Value & Implications Entrepreneurship education is shown to have many positive impacts on subsequent careers. However, entrepreneurial competencies developed through education do not appear to counteract the general gender differences seen in society, as differentiation between male and female graduates is evident through the study. Where previous research has focused on studying these differences, this study instead focuses on how income and work-life balance unfolds across gender categories of venture creation program graduates. These programs have shown to produce graduates who have developed and later utilized entrepreneurial competencies to a high degree in both employed and self-employed contexts. Though in the subsequent careers, the progression of income and work-life balance falls under different mechanisms depending on the gender of the graduate. Women seems to have more stable progression compared to men, with less variation between occupations. Though a limitation lies within that the regressors builds lesser models for women compared to men. This indicates that future research should consider an expanded set of variables or focus on designing qualitative studies target towards career progression of female entrepreneurs. In conclusion this study informs the need to consider the entrepreneurial career progression of women as different compared to their male graduates.

Journal article (peer-reviewed)abstract
- Electrodeposition of Se films from air and water stable 1-butyl-1-methylpyrrolidinium trifluoromethylsulfonate ionic liquid was studied in open air conditions. The electrochemical behavior of H2SeO3 on gold and copper substrates was investigated in ionic liquid-water mixtures, and the influence of the deposition parameters such as time and bath temperature on the crystallinity of the film was examined. For the gold substrate, a reddish deposit containing amorphous, hexagonal and rhombohedral Se phases was identified at room temperature, while a grayish film of hexagonal and rhombohedral phases was formed at higher temperatures. The reddish Se film was found to exhibit a smoother surface with lower reflectivity in comparison to the grayish one. The band gap of the reddish film was close to that of pure amorphous red Se reported in literature, while the band gap of the grayish film was close to the pure hexagonal film. Photoelectron spectroscopy and energy dispersive X-ray spectroscopy show that both films consist of pure Se with only slight surface contaminations by remnants from the electrodeposidon. In the case of a copper substrate, the electrodeposition of Se was accompanied by the formation of copper-selenide due to the reactivity of copper in H2SeO3.

Journal article (peer-reviewed)abstract
- The electrodeposition of thin selenium (Se) films from 1-ethyl-3-methyl-imidazolium trifluromethylsulfonate at room and elevated temperatures on gold and on copper substrates was studied under open-air conditions. The effect of bath temperature on the composition and structure of the deposited films was examined using cyclic voltammetry, chemical analysis and X-ray diffraction analysis. The obtained results showed that on gold substrate and at room temperature, a reddish Se film grows mainly in amorphous, monoclinic, rhombohedral and hexagonal structure, while at temperatures a parts per thousand yen90 A degrees C, a grayish film of hexagonal and rhombohedral structure is deposited. Photoelectron spectroscopy shows that both films consist of pure Se with only slight surface contaminations by remnants from the electrodeposition. Due to the differences in phase structure and the presence of the monoclinic phase, the reddish films showed higher light absorbance. The band gap of the reddish film is close to that of pure amorphous Se reported in literature. Deposition on copper substrate leads to formation of CuSe and CuSe2 at room temperature and at 70 A degrees C, respectively.

Research review (peer-reviewed)abstract
- The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leading technology to cover the available parameter space for weakly interacting massive particles, while featuring extensive sensitivity to many alternative dark matter candidates. These detectors can also study neutrinos through neutrinoless double-beta decay and through a variety of astrophysical sources. A next-generation xenon-based detector will therefore be a true multi-purpose observatory to significantly advance particle physics, nuclear physics, astrophysics, solar physics, and cosmology. This review article presents the science cases for such a detector.

Journal article (peer-reviewed)abstract
- Aims. Studying molecular gas properties in merging galaxies gives important clues to the onset and evolution of interaction-triggered starbursts. The (CO)-C-12/(CO)-C-13 line intensity ratio can be used as a tracer of how dynamics and star formation processes impact the gas properties. The Medusa merger (NGC 4194) is particularly interesting to study since its L-FIR/L-CO ratio rivals that of ultraluminous galaxies (ULIRGs), despite the comparatively modest luminosity, indicating an exceptionally high star formation efficiency (SFE) in the Medusa merger. Methods. High resolution OVRO (Owens Valley Radio Observatory) observations of the (CO)-C-13 1-0 have been obtained and compared with matched resolution OVRO (CO)-C-12 1-0 data to investigate the molecular gas cloud properties in the Medusa merger. Results. Interferometric observations of (CO)-C-12 and (CO)-C-13 1-0 in the Medusa (NGC 4194) merger show the (CO)-C-12 (CO)-C-13 1-0 intensity ratio (R) increases from normal, quiescent values (7-10) in the outer parts (r > 2 kpc) of the galaxy to high (16 to > 40) values in the central (r

A precessing molecular jet signaling an obscured, growing supermassive black hole in NGC 1377?

- With high resolution (0."25 × 0."18) ALMA CO 3-2 (345 GHz) observations of the nearby (D = 21 Mpc, 1" = 102 pc), extremely radio-quiet galaxy NGC 1377, we have discovered a high-velocity, very collimated nuclear outflow which we interpret as a molecular jet with a projected length of ± 150 pc. The launch region is unresolved and lies inside a radius r 40% of the flux in NGC 1377 and may be a slower, wide-angle molecular outflow which is partially entrained by the molecular jet. We discuss the driving mechanism of the molecular jet and suggest that it is either powered by a (faint) radio jet or by an accretion disk-wind similar to those found towards protostars. It seems unlikely that a massive jet could have been driven out by the current level of nuclear activity which should then have undergone rapid quenching. The light jet would only have expelled 10% of the inner gas and may facilitate nuclear activity instead of suppressing it. The nucleus of NGC 1377 harbours intense embedded activity and we detect emission from vibrationally excited HCN J = 4-3?2 = 1f which is consistent with hot gas and dust. We find large columns of H2 in the centre of NGC 1377 which may be a sign of a high rate of recent gas infall. The dynamical age ofthe molecular jet is short (
