    Standardization and modularization of Handling system: Optimization of choice of roller conveyors andloading / unloading tables for beam handling2019Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This project was commissioned by Ficep S.p.a. and performed in the field of product development with the aim of developing a method for the revision of product architectures in standardized modular configurations.The handling system for profiled beams has a generally well-established structure and technology among all main competitors in the mechanical carpentry sector, for this reason the key to success in the market is the optimization of the components to minimize redundancies and the ability to promptly satisfy the variegated customers’ demands while still keeping competitive prices.The major problem in the layout of these systems is the absence of standard rules or mathematical models, relaying mostly on the empirical norms derived from the experience of the designer, thus generating confusion and variants’ proliferation.For this reason, a standardized and optimized model for generating appropriate configurations according to functional specifics is the final goal of this work.To hit this target the development process has been analysed and reviewed all the way from the customer offer request to final layout definition, passing through the definition of the technical specifics, architecture of the handling system and inner structure of its components.The final result is a configurator that, taking the technical specifications of the client as input data, dynamically calculates the structure of the handling system adjusting even the composition of the elements it is made up of and their position for the layout.As a side project the configurator was used to create a model for cost estimation of the handling system in stages prior to the CAD design of its layout.

    Designing an assembly line for modular house manufacturing: Increased efficiency of the manufacturing process2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Having an efficient production is vital for companies that are facing highly demanding customers along with tough competition. In addition, the production layout has a significant impact on the production efficiency hence it the choice of production layout is an important question to consider. A common production layout is the assembly line whereas companies with products that are not adequate for assembly line production; are seeing advantages of working with assembly lines. An example is the modular house manufacturing industry. Therefore, the purpose of the study was to investigate how an assembly line for modular house manufacturing and the related material supply may be designed in order to increase the overall efficiency of the manufacturing process. A single case study has been conducted at Zenergy AB, Skillingaryd. Empirical data has been collected through various sources; interviews, observations and document studies. In addition, a literature review has been conducted. The theoretical framework and empirical data has been established by the means of pattern matching and further on data analysis was done thus the results of the study were acquired. To conclude, it is shown in the results that implementation of an assembly line for modular house manufacturing can be beneficial despite the fact that its products are not adequate for assembly line production. Further on, there are three main critical factors to consider during the assembly line design process for modular house manufacturing. The critical factors are; line balancing, dry time and bulky materials. The critical factors will in turn have a significant impact on the choice of the assembly line production layout and the related material supply.

    Läkemedelshanteringsprocessen: Inom äldreomsorgen hos Socialförvaltningen2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose The purpose of this study is to conduct a survey of the Process of Drug Management in elderly care from when a drug is prescribed to when it is discarded. The purpose also includes to investigate how the various activities are linked to each other and to identify errors for the patient safety. In order to fulfil the purpose, two issues have been formulated: 1. What activities are currently in the Process of Drug Management in elderly care? 2. What deviations can occur in the Process of Drug Management and can be errors for the patient safety? Method In order to fulfil the purpose, a case study was made on the Social Service of the elderly care. Empirical data has been collected through interviews, observations and questionnaires. Further on the empirical data has been analysed and compared with the theoretical framework in order to achieve the purpose of the study. Findings The five main activities which have been identified in the Process of Drug Management are Prescription, Requisition and Check, Storage, Readying and Administration and finally Follow-up. In order to identify errors for the patient safety in the different activities, a value stream map has been designed where the risk has been placed and later on discussed. Errors for the patient safety exist among other factors such as due to lack in communication and information, human factors such as stress, lack of sleep, cultural shocks and lack of motivation for work. The study also shows that there is lack of responsibility among the various operators in the process. Implications The process of drug management in elderly care is a problem area because of its complexity where deviations often occur which results in errors for the patient safety. The guidelines within elderly care are about the same throughout Sweden, which leads to the fact that development in order to prevent errors of the patient safety can take place within other organizations. Deviations are unfortunately making an impact in the first activity, “Prescription”, which contributes to additional deviations in the following activities. In order to improve the patient safety, developing the quality within the organization and within the Process of Drug Management should be a priority. Limitations The aim of the study was to gain a deeper insight into the process of Drug Management and identify errors for the patient safety. Wishful thinking is to investigate several more units in order to get a clearer picture of the problem area from different angles.

    The Impact of Corporate Taxes on Foreign Direct Investment2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis investigates the impact that the corporate income tax rate has on inflows offoreign direct investment (FDI) in high-income OECD countries during the periods1998-2006. The thesis has a small focus on Sweden and how this country’s policies canaffect inward FDI. Moreover, the determinants of FDI are analyzed in order to build amodel that allows to see the influence that the statutory corporate income tax rate has onthese countries. OLS regressions are used to find the degree to which certain variables,specifically the corporate tax rate, have an impact of the dependent variable (i.e.aggregate inflows of FDI). The independent variables are: GDP, skilled labour, labourcosts, economic freedom as a proxy for trade openness and property rights,infrastructure, the corporate income tax rate, dummy variables to account for timeeffects and three dummy variables for continental location targeting whethergeographical location is of relevance of not.It is concluded that the corporate income tax rate does have a significant impact on FDIinflows in OECD members for the specified period. Additionally, economic freedom,gdp and geographical location are also found to be important variables that determinethe inflows of FDI. Other variables are found insignificant in almost all regressions.

    Fixation patterns of individuals with and without Autism Spectrum disorder: Do they differ in shared zones and in zebra crossings?2018In: Journal of Transport and Health, ISSN 2214-1405, E-ISSN 2214-1405, Vol. 8, p. 112-122Article in journal (Refereed)
    Abstract [en]

    Shared zones are a contemporary traffic zone that promotes equality between multiple road users and efficiently utilizes available space, while simultaneously maintaining safety and function. As this is a relatively new traffic zone, it is important to understand how pedestrians navigate a shared zone and any potential challenges this may pose to individuals with impairments. The aim of this study was to utilize eye-tracking technology to determine fixations and fixation duration on traffic relevant objects, non-traffic relevant objects, and eye contact, in 40 individuals with and without Autism Spectrum Disorder (ASD) in a shared zone and a zebra crossing. It was assumed that individuals with ASD would make less eye contact in the shared zone compared to the group of typically developing adults. A total of 3287 fixations across the shared zone and zebra crossing were analysed for areas of interest that were traffic relevant, non-traffic relevant, and eye contact, and for fixation duration. Individuals with ASD did not display any difference in terms of eye contact in the shared zone and the zebra crossing when compared to the controls. All pedestrians were more likely to look at traffic relevant objects at the zebra crossing compared to the shared zone. Individuals with ASD had an overall shorter fixation duration compared to the control group, indicating people with ASD either process information quickly, or they do not process it for long enough, although these findings require further investigation. While shared zones have many benefits for traffic movement and environmental quality, it appeared that pedestrians displayed safer road crossing behaviours at a zebra crossing than in a shared zone, indicating that more education and environmental adaptations are required to make shared zones safe for all pedestrians.

    The 21 st Century Manufacturer:: The Role of Smart Products in the Transition from a Product to a Service Based Focus in Manufacturing Industries2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Service industries have grown extensively over the past few decades on the back of globalized business trends. With increasing competition, product firms are struggling on product sales alone. Hence, both products and services are being bundled into what is known as offerings. Moreover, firms are looking into how they can improve their offerings to meet customer needs with the help of smart products. Smart products are described as products able to communicate and interact with other electronic devices as well as being self aware. One of these examples is conditional monitoring whereby the product is houses built in sensors to communicate with a back end ERP system providing the supplier a transparent view and real-time update into the status and service needs for both the product and customer.

    Purpose: The aim of this thesis is to explore how smart products can help leverage services for product firms moving towards a service focus.

    Method: In addressing the purpose a case study strategy was applied. An inductive approach was used, and interviews were conducted with two Swedish manufacturers, SKF and Atlas Copco. SAP, a software provider was also interviewed. Lastly, a qualitative approach was used and secondary data was collected through annual reports, as well as public company information.

    Conclusions: Smart products show the capability of being able to record, transmit and act upon their behavior and usage. One major finding from the thesis is that smart products enable product firms to extend their service portfolios from a transactional to a relational standpoint through real time information feeds. This includes asset maintenance as well as monitoring and visibility into client operations. In addition, traditional product firms help product firm’s move towards a service strategy. Another finding of the thesis is that information visibility shows a positive co-relation with the service provider’s ability to take on more risk increasing service revenues and customer lock in and increase value co-creation. On the other hand smart products show to be challenging to product firms new to service development. These challenges include increasing initial infrastructure costs and high level of maintenance and complexity of the smart products.

    Informationsflöde inom prefabprocessen: Hur kan Derome Träteknik effektivisera informationsflödet från konstruktion till produktion?2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The study aimed to investigate how the information flow at an off-site fabrication is working, from design-stage to production. More specifically, it focus on identifying effective and ineffective parts in the information flow, along with improvement opportunities to optimize the personnel’s daily work.

    Since the authors had no knowledge about where the problems in the information flow at the company was, they were not able to create a theoretical framework before the case study was made. The case study involved observation and interviews. The observation was made to identify the process and information flow at the company. The interviews were made to get the knowledge about the personnel’s opinion and to locate where the problems in the information flow occurred. With the case study as a base the theoretical framework could be made with a literature study.

    The problem areas that emerged from the case study are all mainly based from the lack of time. This is partly due to the time-consuming activities such as manual handling in the making of production technical drawing and revision of planning documents. The improvement proposal the authors present is to upgrade the computer-aided design software and to implement a planning system. The authors also consider the lack of time as a reason for shortcomings in the communication. The improvement proposal the authors present for this is to keep the personal contact and to supplement it with a system.

    The study intends to contribute with knowledge about how an information flow at an off-site fabrication may look like. It reinforces theories about why it is important to keep the personal communication when a system upgrade are implemented. The study has also contributed in proposals in which parts of the information flow that have potential to become more effective at an off-site fabrication.

    The study was limited to an off-site fabrication and only the information flow between design-stage and production was included in the study. No economic aspects were considered and only one company has participated in the study.

    Informative advertising in monopolistically competitive marketManuscript (preprint) (Other academic)
    Abstract [en]

    In their seminal paper Grossman and Shapiro (1984) find that informative advertising is socially excessive in an oligopoly (entry is also socially excessive). However, to derive the results, it was assumed that all consumers receive at least one ad, i.e., advertising does not have a demand creation effect. Christou and Vettas (2008), Tirole (1988), among others, have presented counter-examples in alternative settings, showing when the assumption does not hold, advertising may socially advertising. Christou and Vettas (2008) also show that quasiconcavity may not hold and present examples in which the equilibrium does not exist as firms would deviate to a higher price. We revisit the question by modeling firms (like consumers) as a continuum, which eliminates the discontinuity that bedeviled both papers and allows us to not use the assumption that all consumers receive at least one ad. As a result, we are able to derive explicit and intuitive conditions for an equilibrium. More importantly, we find instead advertising is socially insufficient regardless of the fraction of the consumers who receive an ad, including when there is effectively no demand creation. We also find that there is insufficient entry instead of excess entry. We provide intuition for the difference between our and previous results, which partly turns on firms deviating to a lower (supercompetitive) price.

    Complexity Classifications for Logic-Based Argumentation2014In: ACM Transactions on Computational Logic, ISSN 1529-3785, E-ISSN 1557-945X, Vol. 15, no 3, article id 19Article in journal (Refereed)
    Abstract [en]

    We consider logic-based argumentation in which an argument is a pair (Phi, alpha), where the support Phi is a minimal consistent set of formulae taken from a given knowledge base (usually denoted by Delta) that entails the claim alpha (a formula). We study the complexity of three central problems in argumentation: the existence of a support Phi subset of Delta, the verification of a support, and the relevance problem (given psi, is there a support Phi such that psi is an element of Phi?). When arguments are given in the frill language of propositional logic, these problems are computationally costly tasks: the verification problem is DP-complete; the others are Sigma(P)(2)-complete. We study these problems in Schaefers famous framework where the considered propositional formulae are in generalized conjunctive normal form. This means that formulae are conjunctions of constraints built upon a fixed finite set of Boolean relations Gamma (the constraint language). We show that according to the properties of this language Gamma, deciding whether there exists a support for a claim in a given knowledge base is either polynomial, NP-complete, coNP-complete, or Sigma(P)(2)-complete. We present a dichotomous classification, P or DP-complete, for the verification problem and a trichotomous classification for the relevance problem into either polynomial, NP-complete, or Sigma(P)(2)-complete. These last two classifications are obtained by means of algebraic tools.

    Abstract [en]

    The aim of the paper is to examine the computational complexity and algorithmics of enumeration, the task to output all solutions of a given problem, from the point of view of parameterized complexity. First we define formally different notions of efficient enumeration in the context of parameterized complexity. Second we show how different algorithmic paradigms can be used in order to get parameter-efficient enumeration algorithms in a number of examples. These paradigms use well-known principles from the design of parameterized decision as well as enumeration techniques, like for instance kernelization and self-reducibility. The concept of kernelization, in particular, leads to a characterization of fixed-parameter tractable enumeration problems.

    Abstract [en]

    The aim of the paper is to examine the computational complexity and algorithmics of enumeration, the task to output all solutions of a given problem, from the point of view of parameterized complexity. First, we define formally different notions of efficient enumeration in the context of parameterized complexity: FPT-enumeration and delayFPT. Second, we show how different algorithmic paradigms can be used in order to get parameter-efficient enumeration algorithms in a number of examples. These paradigms use well-known principles from the design of parameterized decision as well as enumeration techniques, like for instance kernelization and self-reducibility. The concept of kernelization, in particular, leads to a characterization of fixed-parameter tractable enumeration problems. Furthermore, we study the parameterized complexity of enumerating all models of Boolean formulas having weight at least k, where k is the parameter, in the famous Schaefer’s framework. We consider propositional formulas that are conjunctions of constraints taken from a fixed finite set Γ. Given such a formula and an integer k, we are interested in enumerating all the models of the formula that have weight at least k. We obtain a dichotomy classification and prove that, according to the properties of the constraint language Γ, either one can enumerate all such models in delayFPT, or no such delayFPT enumeration algorithm exists under some complexity-theoretic assumptions.

    Enumerating all solutions of a Boolean CSP by non-decreasing weight2011In: Theory and applications of satisfiability testing - SAT 2011: 14th International Conference, SAT 2011, Ann Arbor, MI, USA, June 19-22, 2011. Proceedings / [ed] Karem A. Sakallah, Laurent Simon, Berlin: Springer, 2011, p. 120-133Conference paper (Refereed)
    Abstract [en]

    We address the problem of enumerating all models of Boolean formulæ in order of non-decreasing weight in Schaefer's framework. The weight of a model is the number of variables assigned to 1. Tractability in this context amounts to enumerating all models one after the other in sorted order, with polynomial delay between two successive outputs. The question of model-enumeration has already been studied in Schaefer's framework, but without imposing a specific order. The order of non-decreasing weight changes the complexity considerably. We obtain a new dichotomous complexity classification. On the one hand, we develop new polynomial delay algorithms for Horn and 2-XOR-formulæ to enumerate the models by non-decreasing weight. On the other hand, we prove that in all other cases such a polynomial delay algorithm does not exist, unless P=NP.

    Complexity of logic-based argumentation in Schaefer's framework2012In: Computational models of argument, IOS Press, 2012, no 1, p. 237-248Conference paper (Refereed)
    Abstract [en]

    We consider logic-based argumentation in which an argument is a pair (Φ, α), where the support Φ is a minimal consistent set of formulæof a given knowledge base that entails the formula α. We study the complexity of two different problems: the existence of a support and the verification of the validity of an argument. When arguments are given in the full language of propositional logic these problems are computationally costly tasks, they are respectively ΣP 2- and DP-complete. We study these problems in Schaefer's famous framework. We consider the case where formulæare taken from a class of formulæin generalized conjunctive normal form. This means that the propositional formulæ considered are conjunctions of constraints taken from a fixed finite language Γ. We show that according to the properties of this language Γ, deciding whether there exists a support for a claim in a given knowledge base is either polynomial, NP-complete, coNP-complete or ΣP 2-complete. We also obtain a dichotomous classification, P or DP-complete, for the verification problem.

    Complexity classifications for propositional abduction in Post's framework2012In: Journal of logic and computation (Print), ISSN 0955-792X, E-ISSN 1465-363X, Vol. 22, no 5, p. 1145-1170Article in journal (Refereed)
    Abstract [en]

    In this article, we investigate the complexity of abduction, a fundamental and important form of non-monotonic reasoning. Given a knowledge base explaining the world's behaviour, it aims at finding an explanation for some observed manifestation. In this article, we consider propositional abduction, where the knowledge base and the manifestation are represented by propositional formulæ. The problem of deciding whether there exists an explanation has been shown to be Σ2p-complete in general. We focus on formulæ in which the allowed connectives are taken from certain sets of Boolean functions. We consider different variants of the abduction problem in restricting both the manifestations and the hypotheses. For all these variants, we obtain a complexity classification for all possible sets of Boolean functions. In this way, we identify easier cases, namely NP-complete, coNP-complete and polynomial cases. Thus, we get a detailed picture of the complexity of the propositional abduction problem, hence highlighting the sources of intractability. Further, we address the problem of counting the full explanations and prove a trichotomous classification theorem.

    Abduction is a fundamental and important form of non-monotonic reasoning. Given a knowledge base explaining how the world behaves it aims at finding an explanation for some observed manifestation. In this paper we focus on propositional abduction, where the knowledge base and the manifestation are represented by propositional formulae. The problem of deciding whether there exists an explanation has been shown to beΣp2-complete in general. We consider variants obtained by restricting the allowed connectives in the formulae to certain sets of Boolean functions. We give a complete classification of the complexity for all considerable sets of Boolean functions. In this way, we identify easier cases, namely NP-complete and polynomial cases; and we highlight sources of intractability. Further, we address the problem of counting the explanations and draw a complete picture for the counting complexity.

    Complexity of logic-based argumentation in Post's framework2011In: Argument and Computation, ISSN 1946-2166, Vol. 2, no 2-3, p. 107-129Article in journal (Refereed)
    Abstract [en]

    Many proposals for logic-based formalisations of argumentation consider an argument as a pair (Φ,α), where the support Φ is understood as a minimal consistent subset of a given knowledge base which has to entail the claim α. In case the arguments are given in the full language of classical propositional logic reasoning in such frameworks becomes a computationally costly task. For instance, the problem of deciding whether there exists a support for a given claim has been shown to be Σ 2 p-complete. In order to better understand the sources of complexity (and to identify tractable fragments), we focus on arguments given over formul in which the allowed connectives are taken from certain sets of Boolean functions. We provide a complexity classification for four different decision problems (existence of a support, checking the validity of an argument, relevance and dispensability) with respect to all possible sets of Boolean functions. Moreover, we make use of a general schema to enumerate all arguments to show that certain restricted fragments permit polynomial delay. Finally, we give a classification also in terms of counting complexity.

    Complexité de l’argumentation dans le cadredu treillis de Post2010Conference paper (Refereed)
    Abstract [fr]

    Dans beaucoup de formalisations logiques de l’argumentation un ar-gument est présenté comme une paire (Φ,α), où le support Φ est un sous-ensemble consistant minimal d’une base de connaissances qui implique l’affirmationα. Dans la plupart des scénarii les arguments sont donnés dans le langage completde la logique propositionnelle. Dans un tel contexte le raisonnement est une tâche algorithmique très difficile. Par exemple, décider s’il existe un support pour une affirmation donnée est Σp2-complet. Afin de comprendre ce qui est à la source dela difficulté de ce problème (et d’identifier des fragments résolubles efficacement) nous nous intéressons aux arguments donnés sous la forme de formules propositionnelles dont les connecteurs logiques font partie d’un ensemble de fonctions booléennes donné. Nous considérons quatre problèmes de décision : existe-t-il unsupport pour un argument ? un argument est-il valide ? une formule donnée est-elle pertinente (resp. superflue) dans les prémisses d’un argument ? Nous classifions la complexité de ces problèmes selon tous les ensembles possibles deconnecteurs autorisés.

    Founding conditions and the survival of new firms: An imprinting perspective on founders, organizational members and external environments2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    New firms are important sources of new employment, economic growth and innovation. Yet, a large portion of them do not manage to survive their first years of existence. This is often linked to their initial lack of capabilities, resources, routines and legitimacy. Certain favorable conditions at founding may allow new firms to partially overcome these initial shortcomings, and help them survive. For instance, organizational members’ prior experience may provide knowledge and skills to the new firm. However, it may also act as a constraint. It can lead new firms to follow a prescribed way of doing things which may ultimately threaten their survival. Similarly, certain unfavorable conditions of the external environment at founding may paradoxically offer a fertile ground for new firms to nurture their survival. Thus, whether some founding conditions are good or bad for new firms is still an unanswered question.

    Building on imprinting theory, this dissertation investigates how different founding conditions affect the survival of new firms. At the organizational level, I study founders’ prior working experience in an incumbent family firm, organizational members’ prior shared international experience and prior industry experience, and focus respectively on three types of new firms: entrepreneurial spawns, international new ventures and high/mid-high tech new firms. I use a matched employer-employee dataset to test the effect of different types of prior experience on new firm survival. At the environment level, I propose how population density of similar organizational forms and the mortality of generalist organizations at founding may affect the survival of new family firms.

    Organisational ecology and the family business2015In: Theoretical perspectives on family businesses / [ed] Mattias Nordqvist, Leif Melin, Matthias Waldkirch and Gershon Kumeto, Cheltenham: Edward Elgar Publishing, 2015, p. 18-34Chapter in book (Refereed)
    Abstract [en]

    Organisational ecology has long studied the survival of organisations. However, few studies have focused on how such perspective can be applied to investigate similar topics in distinct organisational forms, such as family businesses. This book chapter thus attempts to apply an organisational ecology perspective to the study of family businesses. More specifically, it explores how such perspective can inform research on the survival of family businesses. Special attention is given to environmental determinants conceptualised at the industry level

    Prior shared international experience and the survival of international new venturesManuscript (preprint) (Other academic)
    Abstract [en]

    This paper shows how organizational members’ prior shared experience in international firms affects the survival of the international new ventures (INVs) to which they belong. I propose that as the length of prior shared international experience (PSIE) increases, these ventures are more likely to draw greater survival-enhancing benefits from the pre-existing routines and capabilities that their members previously developed while working together in the same international firm. However, for high PSIE length, INVs may find it difficult and costly to revise existing routines and capabilities and to develop new ones to achieve survival. Using a unique sample of Swedish INVs, I find that PSIE has an inverted U-shaped relationship with survival. Further, I theorize and show that contextual familiarity between the contexts in which PSIE was acquired and those in which it is applied through the INV is an important contingency of the PSIE-survival relationship. This study has valuable implications for research on international entrepreneurship and shared experience.

    The survival of new family firmsManuscript (preprint) (Other academic)
    Abstract [en]

    Motivated by both the scarcity of studies on the survival of new family firms and the call to better understand how external environments may affect family firms, I apply organizational ecology to outline the potential effects of environmental conditions on the survival of new family firms. This study extends organizational ecology in the context of new family firms, proposes three testable propositions and opens new avenues for research on the ecology of (new) family firms.

    Industry knowledge, prior industry experience and new venture survivalManuscript (preprint) (Other academic)
    Abstract [en]

    Recent research suggests that new ventures can overcome threats to their survival by gaining access to technological knowledge from other firms in their industry even without directly transacting with them or joining their networks. This access can be obtained through vicarious learning that allows new ventures to benefit from spillovers of industry knowledge made public through patents. However, absorbing industry knowledge can be difficult for new ventures. On the one hand, new ventures have different absorptive capacities as a result of their organizational members’ prior experience within the current industry and across different industries. On the other hand, industries differ in the characteristics of their public technological knowledge (i.e., intensity and breadth). We propose that the intensity and breadth of an industry’s public technological knowledge interact with organizational members’ prior industry experience to determine the ability of new ventures to learn vicariously, affecting the likelihood of venture survival. Our results show that having prior experience in the same industry is beneficial for new venture survival when the technological knowledge within an industry is high in intensity and breadth, while prior experience across different industries is beneficial when this knowledge is low in intensity and breadth. This study contributes to the literature on prior industry experience, organizational learning, absorptive capacity and new venture survival.

    Back To The Roots: Inherited Ownership Effects and Spawns’ Performance2014In: Strategies in a World of Networks, 2014Conference paper (Refereed)
    Abstract [en]

    This paper analyzes inherited ownership effects, defined as socialization benefits that employees acquire while working in privately-held firms that may be transferred to a spawn. We test for inherited ownership effects in the population of Swedish entrepreneurial spawns competing in medium-high and high technology manufacturing industries. Preliminary results show that spawns of family-owned businesses survive at a higher rate than spawns of non-family-owned businesses. Moreover, spawns that share family ties with the parent company survive at a higher rate than spawns started by non-family members. This findings suggest the existence of inherited ownership effects that influence the performance of new firms.

    The survival of family-firm spawns2017In: 2017 Annual Meeting of the Academy of Management, AOM 2017, Academy of Management , 2017Conference paper (Other academic)
    Abstract [en]

    We analyze whether entrepreneurial spawns from family firms are more likely to survive than spawns from non-family firms. Using a matched employer employee panel data set, we find that entrepreneurial spawns from family firms survive longer than spawns from non-family firms. To mitigate endogeneity concerns, we used a two-stage model for self-selection into spawning and implemented coarsened exact matching to compare more closely aligned treatment (family parent) and control (non-family parent) samples. We further show that entrepreneurial spawns from family firms survive longer when located closer to the parent firm and when the founder had longer tenure at the parent firm.

    “To have and have not”: founders’ human capital and university start-up survival2014In: Journal of Technology Transfer, ISSN 0892-9912, E-ISSN 1573-7047, Vol. 39, no 4, p. 567-593Article in journal (Refereed)
    Abstract [en]

    In order to preserve innovation, knowledge development and diffusion, as well as the transfer of new technologies, the emergence of University Start-Ups (USU) and their survival as a particular dimension of performance represents a relevant research topic. As USU generally have scarce initial resources, the human capital of their founders is one of their main business assets. Although the survival of such firms is supposed to be heavily dependent on the human capital characteristics of their founders, this has not received enough attention in existing research. In this paper we investigate the contribution of founders’ specific human capital characteristics to the survival of USU, building on Gimeno et al. (Adm Sci Q 42:750–783, 1997) threshold model of entrepreneurial exit. We divide USU founders’ specific human capital into three components (entrepreneurship, industry and university) in order to better understand its impact on firm survival. Our theoretical model is empirically tested on a unique sample of Catalan USU through a logistic regression analysis. Coherently with our theoretical reasoning, the results show that industry human capital negatively affect USU survival, while university human capital and entrepreneurship human capital enhance the likelihood of USU survival.

    Parents' performance in entrepreneurship as a "double-edged sword" for the intergenerational transmission of entrepreneurship2017In: Small Business Economics, ISSN 0921-898X, E-ISSN 1573-0913, Vol. 49, no 4, p. 841-864Article in journal (Refereed)
    Abstract [en]

    We investigate how perceived parents’ performance in entrepreneurship (PPE) affects the entrepreneurial career intentions of offspring. We argue that while perceived PPE enhances offspring’s perceived entrepreneurial desirability and feasibility because of exposure mechanisms, it weakens the translation of both desirability and feasibility into entrepreneurial career intentions due to upward social comparison mechanisms. Thus, perceived PPE acts as a double-edged sword for the intergenerational transmission of entrepreneurship. Our predictions are tested and confirmed on a sample of 21,895 individuals from 33 countries. This study advances the literature on intergenerational transmission of entrepreneurship by providing a foundation for understanding the social psychological conditions necessary for such transmission to occur.

    Critical success factors of potential CPFR implementations: Two manufacturing case studies in Sweden based on a pre-CPFR stage from the perspective of a buyer – seller relationship2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: Higher global competition and more demanding customers force manufacturing companies to develop and adopt new collaborative strategies; the collaborative planning, forecasting and replenishment concept allows stronger supply chain cooperation, cost saving, improved efficiency and performance.

    Purpose: Exploratory, to study the criticality of factors that can affect the feasibility of a potential a CPFR implementation in Sweden, from the perspective of a manufacturer in a pre-CPFR implementation stage.Method: Qualitative research, using a multiple case method of two manufacturing firms operating in Sweden. Using content analysis, it revolves around studying factor criticality, all the while showing differences and commonalities in terms capabilities, and future feasibility of CPFR between the two case studies.

    Findings: High degree of interconnectivity between the factors; the critical success factors for Sweden are relationship and trust, goal alignment, KPI’s and costs, with very important factors such as cross-functional communication, top management support, and lower impacting factors such as IT infrastructure and change management. Relationship and trust, cross-functional communication and change management are developed factors that the Swedish manufacturing firms possess.

    Implications: The study’s contributions are related to the criticality of factors that can affect CPFR implementations in Sweden’s manufacturing sector, showing the importance of each, contributing academically in attempting to fill in the gap related to CPFR in Sweden, and practically by allowing better strategic decision-making in relation to future implementations. This is even more relevant due to a thorough lack of research in this area.

    En jämförande studie av crossplattform- och hybridutveckling2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte – Syftet med studien var att jämföra och utvärdera två utvecklingsmetoder för hybrid- och crossplattformutveckling. Detta syfte bröts ner till två frågeställningar:

    • Hur väl kan de båda utvecklingsmetoderna återskapa animationer för att förbättra användarupplevelsen i en applikation?- Vilka av de 3 utvalda animationerna som visas i meaningful transitions och point of origin går att återskapa i de båda utvecklingssätten?
    • Hur påverkas prestandan vid användandet av de utvalda hårdvarufunktioner som implementerats med de båda utvecklingsmetoderna? – Kameran och minnet.

    Metod – Denna rapport är en fallstudie då den är gjord i samarbete med Knowit Jönköping AB efter deras önskemål. Utvecklingsmetoderna som valdes var PhoneGap och Appcelerator Studio, alltså en för hybridutveckling och en för cross-plattform. En applikation för varje utvecklingsmetod byggdes med identiska funktioner som skulle kunna testas för att besvara frågeställningarna. Två kvantitativa insamlingar gjordes i form av enkätundersökning av testpersoners uppfattning av animationerna och en insamling av prestandamätningar vid hårdvaruanvändning.

    Resultat – Resultatet från studien visar att minnesåtgången vid hårdvaruanvändning är både låg och nästan identisk för de båda utvecklingsmetoderna. Empirin visar även att animationerna på båda metoderna kan leva upp till Googles riktlinjer enligt testpersonerna och upplevs som positiva. En notering är dock att Appcelerator tycks ha en liten fördel vad det gäller animationerna. Denna fördel är relativt liten och gör egentligen ingen större skillnad för vilken metod som kan anses som den bästa.

    Implikationer – Studien bidrar till att underlätta valet för mjukvaruutvecklare och företag som funderar på att använda sig utav någon av utvecklingsmetoderna. Detta genom att visa att prestandan vid hårdvaruanvändning inte är något att lägga stor vikt på. För användargränssnitt och användarupplevelse finns en mindre skillnad då Appcelerator använder sig utav native SDK och får en liten fördel när det kommer till användarupplevelsen. Detta kan dock justeras för PhoneGap då det med lite extra jobb går att styla applikationen till att se mer native ut. Utvecklare kan därför tänka på vilka kunskaper de har sedan innan vad gäller XML/HTML och styling då de ska välja utvecklingsmetod.

    Begränsningar – Utvecklingen är gjord av förstagångsanvändare av PhoneGap och Appcelerator Studio vilket kan ha påverkat kvalitén på animationerna och användargränssnittet. En tredjepartsapplikation användes vid mätning av prestandan då PhoneGap saknade plugin för det. Detta kan ha haft en påverkan på resultatet.

    Managing integration of organizational culture within acquisitions: A Case Study on a Swedish business consulting firm.2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The amount of acquisitions has been increasing over the last decades and has been used as a growth strategy by firms all over the world. However, more than fifty percent of all acquisitions never deliver the initially expected value, which in many cases is due to poor integration management of the organizational culture in the post-acquisition phase. Where, in contrast, acquisitions which are integrated into the organizational culture of the acquirer, can see a decrease in social conflicts and receive a higher employee commitment. Which in turn can help the acquisition to provide and remain its human capital and value. 

    With the support of a Swedish business consulting firm, this study hopes to shed light upon how firms integrate organizational culture in the post-acquisition phase, and which integration management tools are used in the process. This study uses a single opportunistic case study combined with a qualitative and an inductive approach, to gather and handle the data. Where the empirical data was mainly collected through interviews. The results of this thesis show that integration of organizational culture in the post-acquisition phase, is mainly managed through supportive leadership and training, in the business consulting firm. Where those main management activities consist of several different integration management tools.

    Collaborative practice - an action research approach to efficient ITSM2011In: 1 st International & Inter-disciplinary Workshop on Practice Research, 2011Conference paper (Refereed)
    Abstract [en]

    This paper addresses collaborative research as an action research approach. Many times action research is described as embracing one research organisation and one business organisation. We are challenging this view by introducing the concept of collaborative practice. A collaborative practice can be seen as a cluster of local practices and researchers working together. In this way, a collaborative practice should enable joint learning between, and joint development efforts for, several business practices as well as contributing to general practice and the scientific body of knowledge. Based on a case study within efficient IT Service Management (ITSM), the concept of collaborative practice and its relation to other adjacent concepts (such as local practice, general practice and scientific body of knowledge) have been characterized. Our results should be viewed as preliminary since they are gathered from an ongoing project.

    Ramverk för inköp2011Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Inköpsavdelningen är en viktig del i företag som ansvarar för att artiklar finns tillgängliga när de behövs. Inköps uppgift är att köpa rätt kvantitet av rätt kvalitet i rätt tidpunkt från rätt leverantör till rätt pris. Detta arbete kan underlättas om tydliga riktlinjer för hur inköpsarbete bör bedrivas finns.

    Swisslog-Accalon AB i Boxholm vill omarbeta sina inköps- och materialplaneringsrutiner, då många av de inköp som görs baseras på inköparens erfarenhet och kunskap om artiklarna samt att många inköp görs mot specifika kranprojekt. Detta har lett till att artiklar i många fall köps utan hänsyn tagen till de mest ekonomiska aspekterna då vanligtvis inga partiformningsmetoder används.

    Syftet med examensarbetet är att skapa ett ramverk för inköp av standardartiklar till företagets kranproduktion, för att inköpsarbetet på företaget ska underlättas och minskas. För att uppfylla syftet med examensarbetet har fyra frågor arbetats fram:

    1. Hur ska standardartiklarna i kranproduktionen klassificeras?
    2. Vad ska ingå i de olika emballagekategorierna?
    3. Vilka är de ekonomiska behovstäckningstiderna för standardartiklarna i kranproduktionen?
    4. Hur ska ramverket användas?

    Relevant empiri har samlats in med metoder som intervjuer och observationer samt att tillgång till nödvändiga dokument och arkivmaterial har erhållits. Empirin som samlats in har analyserats med litteratur inom det aktuella området.

    Resultatet av examensarbetet är ett framarbetat ramverk som beskriver hur inköpsarbetet av företagets standardartiklar till kranproduktion rekommenderas att bedrivas. Dessutom kommer ramverket att underlätta och minska inköpsarbetet, då företaget rekommenderas att styra vissa av artiklarna med enkla och tidseffektiva metoder.

    Influencing Factors in the Implementation of Green Management Practices: A Qualitative Study regarding Swedish SMEs in Logistics2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The subject of green management is today relatively unexplored in existing literature, especially regarding SMEs in logistics. To bridge this gap this study aims to find what factors influence the implementation of green management for SMEs in logistics. Furthermore, this study aims to address the influential weight of these factors to create an even greater understanding within the topic.

    The chosen research method of this paper is qualitative, and the empirical data is collected through semi-structured interviews with Swedish logistic companies who have acquired the environmental management system ISO 14001. Furthermore, the research approach of this study is deductive.

    When implementing green management, this paper has found 4 factors that influence a company in various ways. What also has been found is what factors that have more influential weight and are essential to make such implementation effective.

    The study provides both theoretical and practical implications. Theoretically it fills a gap current literature and further explains SMEs in logistics use of green management. Practically companies can draw from this study to see if they work effectively with green management or better prepare for a transition. The researchers of this study suggest that the factors of influence that are presented in the empirical findings should be tested in a quantitative study with a larger sample size to better measure the effect of each one in a practical context.

    Superkvinnorna: En semiotisk innehållsanalys av Andra Avenyn och Bonusfamiljen ur ett genusperspektiv2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The goal with this qualitative semiotic analysis is to enlighten awareness regarding gender development. This, by examining how women are pictured in two Swedish tv series, Andra Avenyn and Bonusfamiljen. Two female main characters from each series are examined in terms of gender roles, stereotypes and norms in order to see if and how the female role differs between the series. The study also aims to answer whether Bonusfamiljen is normative or not in comparison to Andra Avenyn. This, in consideration to their different production years. The questions are answered through analysis of selected scenes. These are examined based on a denotative and a congenational level. In support to the analysis, a schedule has been developed. This is based on two themes: "interactions" and "personality". The theoretical framework used in this study includes gender and feminist theory. 

    The result shows that the characters are created with great awareness regarding gender and feminism. The women are independent and strong and thus reflect the "modern woman". However, one of the female main characters in Bonusfamiljen reflects a more gender stereotypical image compared to the characters in Andra Avenyn. Although, both series show a more modern look on gender roles.

    Entrepreneurial orientation in family firms: A generational perspective2012In: Small Business Economics, ISSN 0921-898X, E-ISSN 1573-0913, Vol. 38, no 1, p. 33-49Article in journal (Refereed)
    Abstract [en]

    We adopt a generational perspective to investigate entrepreneurial orientation (EO) in family firms. We test a model that determines how the influence on EO of external factors and internal factors differs in first-, second- and third-and-beyond-generation family firms. We argue that while the founder is vital in the first generation, EO is more subject to interpretations of the competitive environment in the second generation and that in the third generation and beyond, access to non-family resources drives EO to a greater extent. Our findings show that perceptions of the competitive environment and EO correlate differently in family firms, depending on the generation in charge, and it is generally stronger in second-generation family firms. Further, we find that non-family managers on the top management team makes a positive difference for EO only in the third-generation and beyond family firms. The significance of non-family investors’ on EO is particularly strong in third-generation-and-beyond firms.

    Developing social interactions through outdoor education in multicultural preschool settings: Teachers’ perspectives2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this study was to identify and investigate preschool teachers’ experiences and views on the role of outdoor education on social interactions. The research questions were: How do the teachers conceptualize outdoor activities’ role on social interactions in multicultural preschool settings? How do the teachers foster social interactions through outdoor education? What kind of challenges have the teachers faced regarding outdoor education in multicultural preschool groups? Semi-structured interviews were conducted with five preschool teachers from three different preschools in a multicultural suburb in southern Sweden. The results showed that – despite children’s possible aversions to engaging in activities in the outdoors - outdoor activities are supportive of the development of closer bonds within the group. According to the teachers interviewed, the natural settings bring calmness and openness, therefore this environment facilitates social interactions among children. The lack of strictly preplanned activities offer children opportunities to follow their interests and to have shared experiences through the discovery of nature. Their willingness for collaborative explorations is a basis for joint play, discussion and group work.
