    Performance outcomes from reciprocal altruism: a multi-level model2019Inngår i: Journal of Small Business and Entrepreneurship, ISSN 0827-6331, E-ISSN 2169-2610Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In recent years, many small- and medium-sized firms have joined formal strategic networks in an effort to enhance firm performance. We set out to examine how altruistic behavior by these firms affected their performance at different levels of altruistic norms within their network. Using a multi-level analytic approach and data from a population of Swedish strategic networks, we found significant cross-level moderating effects that explained variance in firm-level performance. The results showed that firms participating in strategic networks benefit more from being altruistic when other network members generally display high levels of altruism. Apparently, altruistic behaviors are rewarded relative to a general network norm. The potential to perform well thus depends on aligning a firm’s altruistic behavior with the general level of altruism in its network.

    Entrepreneurs' coping with challenging role expectations2007Inngår i: Baltic Journal of Management, ISSN 1746-5265, E-ISSN 1746-5273, Vol. 2, nr 3, s. 288-304Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose - The purpose of this study is to analyze entrepreneurs' coping strategies used to face stakeholders' expectations. Design/methodology/approach - The paper draws from the general management, role theory, and entrepreneurship literature to develop hypotheses that are tested by using hierarchical regression techniques on a sample of 183 Slovenian entrepreneurs. The paper develops and tests four coping strategies (structural role redefinition, personal role redefinition, reactive role behavior, and passive role behavior) to assess influence on new venture performance. The analysis examines moderating effects of entrepreneurs' perceived role-related stress. Findings - Results reveal that coping strategies focused on reducing expectations and/or working harder to meet expectations positively affect new venture performance. However, entrepreneurs' focus on suppressing perceived expectations negatively influences new venture performance. Furthermore, entrepreneurs' role-related stress moderates the relationship between reactive role behavior and new venture performance. Research limitations/implications - This study provides a better understanding of types of coping strategies available to entrepreneurs and practical consequences for new venture performance. It also explores why some entrepreneurs perform well and why some may quit early being an entrepreneur while others remain and prosper in their role. Possible study limitations are discussed due to sample characteristics and measurement. Practical implications - The study results are relevant for practising and nascent entrepreneurs, support organizations, and policy makers since empirical evidence can be used in designing entrepreneurs' training and competency-building programs. Originality/value - This study is among the first to illustrate effects on early entrepreneurial performance of coping strategies to meet stakeholders' expectations and, indirectly, entrepreneurs' ability to endure establishing a new venture.

    Abstract [en]

    This study analyzes entrepreneurs' coping strategies to manage stakeholders' expectations. We develop and test four coping strategies (structural role redefinition, personal role redefinition, reactive role behavior and passive role behavior) to assess influence on new venture performance. The analysis considers potential moderating effects of entrepreneurs' perceived role-related stress. We draw from the general management, role theory, and entrepreneurship literature to develop hypotheses, tested using hierarchical regression based on responses from 183 Slovenian entrepreneurs. Results reveal that coping strategies focused on reducing expectations and/or working harder to meet expectations positively affect new venture performance. However, entrepreneurs' focus on suppressing perceived expectations negatively influences new venture performance. Furthermore, entrepreneur's role-related stress moderates the relationship between reactive role behavior and new venture performance. This study provides a better understanding of types of coping strategies available to entrepreneurs and practical consequences for new venture performance. It also explores why some entrepreneurs perform well and why some quit early while others remain and prosper in their role. We acknowledge possible limitations due to sample characteristics and measurement. The study provides practicing and nascent entrepreneurs, support organizations, and policy makers with evidence for use in the design of entrepreneurs' training and competency-building programs.

    Board composition and firm performance: a test of the upper echelon perspective of entrepreneurship, innovation and competitiveness2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Principal TopicThe role and influence of board composition on firm performance and development has been extensively debated over the last decades. In 1984, Hambrick and Mason published their seminal work introducing the perspective of upper echelons. This perspective suggests that the demographic characteristics of firm boards may exert influence over firm performance since the demographics are associated with many cognitive bases, values, and perceptions thatguide and direct board members decision-making and functions. Several studies have found empirical results supporting these arguments and have further developed the conceptual reasoning for a relationship between upper echelon characteristics and firm performance. However, the wide array of theoretical underpinnings and perspectives combined with diverse empirical evidence has presented further questions over time in relation to how board composition influences firm performance and entrepreneurial levels in firms.In an attempt to address these questions, we model and test the relationship between board composition and firm performance and entrepreneurial levels. We propose a set of hypotheses that suggest that board composition can influence the potential of the boards to support effective monitoring and that composition also have influence of the human and relational capital of the boards. Overall, we suggest that board monitoring and board capital mediates the relationship between board composition and firm performance.MethodThe hypotheses were tested in a three year longitudinal data set including full responses from a sample of 296 firms drawn from a population of Swedish firms. In total were 1167 firms surveyed in the study and approximate 25% responded with completed surveys for the time period. A structural equation modeling approach including mediation models and control for lagged effects were adopted to perform tests.In the light of previous findings, we examine the relationship of both subjective and objective measures of firm performance and we also include longitudinal data to account for potential lagged effects. Besides examining board composition influence over traditional measures of performance, we examine how board composition influences firm levels of entrepreneurial orientation and innovation as well.In doing this we include a set of competing models where board composition variables are hypothesized to influence firm performance and entrepreneurial levels through board functions as board monitoring and board capital. Nested model tests are adopted to determine mediation and to decide how competing models and theories work in predicting firm performance through board composition.Results and ImplicationsResults indicate that board composition exerts influences over both firm performance and entrepreneurial levels in the studied firms. Overall, board composition both influences the firms’ ability to exert effective monitoring and contribute with human and relational capital to the firm that in turn are vital areas for the firms in order to perform well. The study has implications for entrepreneurship as it shows the importance of board composition upon firm performance and entrepreneurial levels. The study also contributes to current debates in upper echelon literature by including models of how the relationship between board composition and firm performance is mediated by board functions in terms of board monitoring and board capital. The study includes competing models and tests arguments from alternative theories when examining the role of board composition.

    Regional innovation and development: a latent growth model of regional innovation determinants2011Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We propose arguments supporting regional innovation to be dependent upon the simultaneous influence of movement of citizens and the industry structure within the region. Our hypotheses state that regions with a high industry concentration gain relatively more from individuals moving in respectively out from the region compared to regions with a low industry concentration. We tested our model and hypotheses on a four year longitudinal data from official registers on the complete population of 290 Swedish municipalities. Results support that regions with a high industry concentration gain innovation activity from increases in both in- and outflows of citizens from the region. Results on regions with a low industry concentration are inconclusive but indicate, in support of our arguments, that such regions gain relatively more from stability (i.e., low movement) in the region.

    The role of motive congruence in strategic networks2007Inngår i: The first Nordic innovation research conference - Finnkampen / [ed] Harri Haapasalo; Päivi Iskanius, Oulu: University of Oulu, 2007, s. 242-251Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Based on thoughts from literature on organizational fit, this study focuses on understanding why some firms gain more from network participation than others. We hypothesize that firms performance from participating in networks is dependent on network motive congruence and that this relationship is moderated by entrepreneurial orientation. Analysis of 55 organizations from two networks supports the role of  network motive congruence for internally oriented motives, such as concerning economies of scales and joint research and development motives. However, motive congruence appears not as important in matters of externally oriented motives, such as entering new markets or sustaining existing market positions. Findings indicate that entrepreneurial orientation can moderate the relationship between network motive congruence and networking performance.

    Immersion and gameplay experience: a contingency framework2010Inngår i: International Journal of Computer Games Technology, ISSN 1687-7047, E-ISSN 1687-7055Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The nature of the relationship between immersion and gameplay experience is investigated, focusing primarily on the literature related to flow. In particular, this paper proposes that immersion and gameplay experience are conceptually different, but empirically positively related through mechanisms related to flow. Furthermore, this study examines gamers' characteristics to determine the influence between immersion and gameplay experiences. The study involves 48 observations in one game setting. Regression analyses including tests for moderation and simple slope analysis are used to reveal gamers' age, experience, and understanding of the game, which moderate the relationship between immersion and gameplay experience. The results suggest that immersion is more positive for gameplay experience when the gamer lacks experience and understanding of the game as well as when the gamer is relatively older. Implications and recommendations for future research are discussed at length in the paper.

    Determinants of capital structure in new ventures: Evidence from Swedish longitudinal data2006Inngår i: Journal of Developmental Entrepreneurship, ISSN 1084-9467, Vol. 11, nr 4, s. 277-296Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The early years are seen as a crucial period for the survival of ventures and yet only a limited number of studies have focused on successful new ventures when studying capital structure. Furthermore, only a few studies have included longitudinal data, tracking ventures over time, or have elaborated on the difference between short-term and long-term debt ratios when studying capital structure. In this paper, hypotheses are developed, based on capital structure theories and literature on new venture financing, and are tested on longitudinal empirical data. Results of multivariate analysis, through structural equation modeling, reveals that: (1) asset structure assists in explaining the variance in capital structure; (2) explained variance in dependent variables is decreasing for each of the four years studied; and (3) multi-group analysis reveals that the determinants influence short-term and long-term debt differently in the first four years of venture existence. Implications of this study suggest that determinants of capital structure in new ventures require theorizing of its own and demand special attention in entrepreneurial policy-making.

    Editorial: Entrepreneurs under pressure : The tensions and dark sides of entrepreneurial life2012Inngår i: International Journal of Entrepreneurial Venturing, ISSN 1742-5360, E-ISSN 1742-5379, Vol. 4, nr 4, s. 237-329Artikkel i tidsskrift (Annet vitenskapelig)
    Abstract [en]

    Scholarly studies, as well as policy makers, have for a long time put entrepreneurs as of great importance for bringing growth and occupation to society. Most studies have subsequently researched success and the road to success (i.e. positive consequences of entrepreneurship) by studying a host of factors related to strategy formulation, influence of environment, growth intentions, motivation, together with competence and experience levels among entrepreneurs. Still, we know that the success is often not obtained without sacrifices and strong commitment. Many entrepreneurs can witness that the road to success is not without obstacles and that establishing a new venture can be extremely hard work. Signs of to large sacrifices would be burn-out syndromes, tension, depression, extensive conflicts between work and family, and increasing sick leave. It is not that surprising that these issues have not received so much attention thus far in entrepreneurship studies. Despite this, we know that the costs for disablement and other negative consequences can be high. There are a number of stakeholders (for instance, employees, investors, banks, and society) besides the entrepreneurs that can suffer significantly if the entrepreneurs make too large a sacrifice or fail to establish and organise a venture around a spotted opportunity. As a response, this special issue invites studies focusing on the existence of threats and pressures in entrepreneurial life, focusing on tensions and darker sides related to opportunity recognition and exploitation. While doing so, the special issue does not exclude positive consequences. On the contrary, studies aiming to reveal the tensions between positive and negative consequences of entrepreneurship are strongly encouraged.

    Extending the stressor-strain perspective: A review and elaboration of the possibility to reverse causality in role stress models2011Inngår i: Role of stress in psychological disorders, Hauppauge, N.Y: Nova Science Publishers, Inc., 2011, s. 113-128Kapittel i bok, del av antologi (Annet vitenskapelig)
    Abstract [en]

    Although the current state of role stress research has to a large extent determined significant consequences, we highlight that the field do not acknowledge the complexity of role relationships, especially occasions of reverse causality. In opening a dialogue, we discuss the possibility to an extension of the stressor-strain paradigm, that is the dominant perspective in role stress research, from explaining linear causal chains of detrimental consequences of role stress to instead researching reversed causality relationships with alternatives theories. Although we concur with previous findings, we elaborate upon the fact that what have long been indicated as important consequences of role stress may also be antecedents to role stress. This paper examines theoretical implications of questioning causality, review typical causal role stress models and outline some method implications for using a cross-lagged design for researching reversed causality of the current role stress consequences

    Abstract [en]

    Role stress has received a lot of research attention in psychological, sociological, and organizational studies over the last several decades. Based on a literature review of about 300 journal articles, this article examines prominent consequences of role stress. Specific focus is on researching differences in relationships between facets of role stress (i.e., role ambiguity, role conflict, and role overload) and frequently cited consequences using techniques of meta-analysis. Findings indicate that each role stress facet has a different relationship with the eight consequences studied. Role stress research can benefit from looking at each facet individually in addition to role stress generally

    Role stress, exhaustion, and satisfaction: a cross-lagged structural equation modeling approach supporting Hobfoll's loss spirals2010Inngår i: Journal of Applied Social Psychology, ISSN 0021-9029, E-ISSN 1559-1816, Vol. 40, nr 6, s. 1357-1384Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study applies Hobfoll's notion of loss spirals to argue for a reciprocal relationship between role stress and 2 of its most commonly studied consequences: exhaustion and satisfaction. By means of structural equation modeling and a cross-lagged design of 116 business managers, the researchers found support for a relationship between role stress and exhaustion. They also found that satisfaction influences role stress, a relationship that the existing literature has not examined. The study contributes a more complex understanding of the relationship between role stress and its modeled outcomes than has been achieved previously.

    When critical mass can become a mess: a contingency model of regional innovation dynamics2011Konferansepaper (Fagfellevurdert)
    Abstract [en]

    A common argument for why some regions perform relatively worse in developing innovations is that they lack sufficient critical mass to compete relative other regions in the development of knowledge-economy innovations and business models. In this study we examine the relationship between population size and regional innovation and also influence from regional contingencies. We test hypotheses using data from official registers related to a population of Swedish municipalities (n=290) over a five year period. We adopted a lagged hierarchical regression technique with a population-averaged negative binomial estimation model where we controlled for the dependent variable at t-1. Results support a non-linear, inverted u-shape, relationship between critical mass and regional innovation. Further, results also suggest that the regional level of education support can mitigate the negative effects of a too large population.

    CRT flicker and scan-line direction1987Inngår i: Displays (Guildford), ISSN 0141-9382, E-ISSN 1872-7387, Vol. 8, nr 2, s. 75-78Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A brief review of the literature covering the perception of flicker is followed by a description of experiments to investigate flicker mechanisms, using a VDU with a light background and with a minimum refresh rate of 70 Hz. A previous hypothesis that there is a link between scan-line direction and perception of flicker was not upheld, although there was support for the view that 70 Hz may not be a high enough refresh rate to ensure freedom from flicker in large displays.

    Transportation demands: of chilled and frozen groceries2019Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [en]

    Today focus on the environemnt is bigger than ever before. UN writes in their climate agenda that they by 2030want to cut the food waste per capita in half. There are strict regulations today regarding how food needs to betransported and stored, but as soon as the consument takes, for example, milk from the frigde at a store there areonly a few guidelines about how the product should be stored. If a chilled or frozen product is not kept insidethe range of the given temperature, a microbilogical growth will begin. This leads to that the food goes bad or,in worst case, that the consumer gets poisoned. There is a change happening today in how the consumers shoptheir food and more focus is layed upon the customer to handle their grocery shopping by themselves.

    This project focuses on developing a solution that will help the consumer to keep their food at the right temperatureduring an extended period of time. The project is carried out in Stockholm during 20 weeks in collaborationwith IKEA of Sweden in Älmhult. The target group in this project is IKEA’s broad customer group.With help from a Human Centered Design process this project goes through the three phases; inspiration,ideation and implementation. The project has been formed with interaction through workshops with differentexternal actors like users and focus groups. The ideation resulted in four simpler concepts that verged in to twothrough external decision making with supervisors from IKEA of Sweden. During the project, the prototypeshave been used together with users to evaluate the usability of the concepts.

    The result consists of two concepts; Behålla and Blåsa, that are aimed to meet two different users that hasbeen identified through surveys and interviews. Behålla is a smaller product that is target towards the user thatbrings food with them to work or school, also to those who buys less groceries at the store. Blåsa is, in contrastto Behålla, a bigger product that is targeted towards the customers that buys a bigger set of chilled and frozengroceries. Additionally four color variations has been created to offer IKEA alternative executions. These conceptsare visualized with renderings through Adobe Illustratior. With these concepts IKEA can enlarge theirsustainability profile and offer their customers two new products to keep their chilled and frozen foods cold.

    Minskning av damm vid hantering av malmpellets: En studie av LKAB:s malmhamn2019Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    LKAB's iron ore harbour in Luleå is the final step in LKAB's southern logistics chain. This study focuses on the product pellets, which is a round ball made of iron ore concentrate. The pellets are transported by train to Luleå iron ore harbour from Malmberget. During the handling process of the pellets friction and abrasion is created, damaging the pellets and leading to a spread of fine particles and dust. The shard, fines and dust that has been created is greatest in Luleå, since the product then has been handled through the whole logistic chain. In the harbour, just before the pellets are loaded into a boat, the fines are separated from the pellets in a screening process. The variation in quality of product that is arriving to the iron ore harbour is large. These differences cause great variation in the amount of dust inside the plant and outside, when the product is loaded in a boat. Today, the iron ore harbour is run by operators with only a partially developed production strategy. The solution today if the cargo is dusty, is that the operator either reduces the loading flow or increases the amount of water that is sprayed on the pellets.

    After a long period of work with optimizing the dust extraction in the iron ore harbour, I came to the conclusion that the dust extraction was very difficult to reduce further. The solution to the remaining dust problems requires other measures.

    The starting point for this research has been to study science of material handling and particle size segregation in materials. Through an increased understanding of material and how MPBO and MPF segregate when they are mixed together, in the different handling steps in an industrial process. I started the investigation to find the various parameters that create the variation in dust. Increased knowledge gives an opportunity to be able to handle the product more efficiently and find methods and parameters that effect the dust. An overall goal of this essay has been to get desired results without slowing down the loading speed.

    At the same time, there has been a desire to understand how all parameters affect the result. To get as good insight as possible, with relatively few tests, a study plan has been established and a 26-2 factor tests have been conducted. The results have been studied to gain an increased understanding of how the various factors affect the amount of dust. With this understanding, the various factors have been optimized.

    The work resulted in a significant reduction of dust both within the plant and also in the external environment. Several of the suggestions for improvements are already implemented in the ore harbour.

    Att rekrytera nyanlända: En kvalitativ studie av privata arbetsgivare2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    För att nå det svenska integrationsmålet krävs att fler nyanlända kommer ut i arbete. Forskning på området visar att den svenska arbetsmarknaden blir alltmer segregerad och att privata arbetsgivares föreställningar och handlande i rekryteringsprocessen är av stor betydelse för de nyanländas situation på arbetsmarknaden. En anledning till varför nyanlända har svårt att etablera sig på arbetsmarknaden handlar om en systematisk diskriminering i rekryteringsprocessen som bland annat kan förklaras av etnosocialitet bland arbetsgivare. Förutom dessa skäl har språket och problematiken att validera de nyanländas tidigare erfarenheter och kunskap betydelse. Forskningen visar även att mångfaldsarbete, CSR och socialt ansvar blivit vanligare förekommande de senaste åren hos privata arbetsgivare.

    Studiens syfte är att se vilka erfarenheter en arbetsgivare har av att anställa nyanlända. Frågeställningarna i studien har varit vilka föreställningar arbetsgivarna har men även vilka handlingar som styr deras val med hänsyn till den ekonomiska och sociala aspekten. Den teoretiska utgångspunkt som förklarar arbetsgivares handlingar i valet att anställa nyanlända är Webers teori om sociala handlingar. Studien är en fallstudie av fem företag och metoden som används är kvalitativa intervjuer som genomförts i Piteå Kommun och Stockholm stad. Intervjupersonerna är chefer inom olika branscher i den privata tjänstesektorn med erfarenhet av att anställa nyanlända i sina företag. I samband med anställningarna erbjuds företagen ett ekonomiskt stöd av Arbetsförmedlingen för de nyanländas introduktion i företaget.

    Resultatet i studien visar att kommunernas stöd till företagen är av stor betydelse och att bristen på arbetskraft har en stor påverkan på företagens val att anställa nyanlända. Cheferna i företagen pekar på exceptionellt många fördelar med de nyanlända medarbetarna som bland annat handlar om lojalitet och arbetsmoral de saknar hos de svenska medarbetarna. Strävan efter en arbetsplats med etnisk mångfald och viljan att göra en god gärning för företaget och Sverige i stort är ytterligare skäl företagen pekar på. Fokuset ligger på samspelet mellan den ekonomiska och sociala aspekten som visar att även om den ekonomiska vinningen är av hög betydelse för många av företagen är ändå det sociala ansvaret en förutsättning till att anställa nyanlända. På sikt är de etiskt värdegrundade besluten en arbetsgivare inom den privata tjänstesektorn fattar avgörande för de nyanländas etablering på den svenska arbetsmarknaden.

    Believing Androids?: fMRI activation in the right temporo-parietal junction is modulated by ascribing intentions to non-human agents2017Inngår i: Social Neuroscience, ISSN 1747-0919, E-ISSN 1747-0927, Vol. 12, nr 5, s. 582-593Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Attributing mind to interaction partners has been shown to increase the social relevance we ascribe to others’ actions and to modulate the amount of attention dedicated to them. However, it remains unclear how the relationship between higher-order mind attribution and lower-level attention processes is established in the brain. In this neuroimaging study, participants saw images of an anthropomorphic robot that moved its eyes left- or rightwards to signal the appearance of an upcoming stimulus in the same (valid cue) or opposite location (invalid cue). Independently, participants’ beliefs about the intentionality underlying the observed eye movements were manipulated by describing the eye movements as under human control or preprogrammed. As expected, we observed a validity effect behaviorally and neurologically (increased response times and activation in the invalid vs. valid condition). More importantly, we observed that this effect was more pronounced for the condition in which the robot’s behavior was believed to be controlled by a human, as opposed to be preprogrammed. This interaction effect between cue validity and belief was, however, only found at the neural level and was manifested as a significant increase of activation in bilateral anterior temporoparietal junction.

    A dynamic approach to real-time performance measurement in design projects2017Inngår i: Journal of engineering design (Print), ISSN 0954-4828, E-ISSN 1466-1837, Vol. 28, nr 4, s. 255-286Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Recent developments in engineering design management point to the need for more dynamic, fine-grain measurement approaches able to deal with multi-dimensional, cross-level process performance in product design. Thus, this paper proposes a new approach to the measurement and management of individual and teamwork performance in engineering design projects. This integrates multiple, previously disparate, aspects of design management and performance measurement theory in a single framework. Further, a fully realised performance measurement approach is developed, which complements existing management strategies. This framework is synthesised from an extensive review and illustrated via an in-depth case study. As such, this work contributes to performance measurement theory in engineering design and has significant implications for both engineering design research and industry.

    Work Sampling of Product Development Activities2016Inngår i: Technical Gazette, ISSN 1330-3651, E-ISSN 1848-6339, Vol. 23, nr 6, s. 1547-1554Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    For effective management of development projects, it is necessary to take into consideration its socio-technical perspective – working processes, teamwork and features of the working environment. Data gathering about socio-technical aspects of the product development activities is often hampered by constraints of the actual working environment in R&D organizations. For that reason, to support practical data collection, the work sampling application for mobile phones has been introduced. The work sampling application consists of sequence of input screens with predefined input menus enabling data gathering about different aspects of the product development activity (such as work type, activity type, context, participants, execution manner, information transaction and motivation). For validation of the proposed application, the empirical study was carried out in the company whose research and development activities are focused on the systems for the generation, distribution and transformation of electrical energy.
