Incubators and new technology-based firms - A resource-based view of development
- 2006
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)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.

The Impact of User Weight on Brands and Business Practices in Mass Market Fashion
- 2010
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Overweight people claim to be mistreated by the fashion industry. If they were, it would be in line with branding theory supporting the idea of rejecting fat consumers to improve user imagery for fashion brands. However, fashion companies do not confess to such practices.To shed some light on the subject, I have conducted two studies.The first attempts to illustrate what effect, if any, user imagery has on fashion brands. It is an experiment designed to show how the weight of users affects consumers’ perceptions of mass market fashion brands. The findings show that consumers’ impressions of mass market fashion brands are significantly affected by the weight of its users. The effect of male user imagery is ambiguous. For women’s fashion on the other hand, slender users are to be preferred.In the second study I examine what effects these effects have on assortments. I compare the sizes of mass market clothes to the body sizes of the population. No evidence of discrimination of overweight or obese consumers was found -quite the contrary.The reasons for these unexpected findings may be explained by the requirements a brand must fulfil to make management of the customer base for user imagery purposes viable. The brand must be sensitive to user imagery; a requirement that mass market fashion fulfils. However, it must also be feasible for a company to exclude customers, and while garment sizes can be restricted to achieve this, the high volume sales strategy of mass market fashion apparently cannot.

Human Factors Approach for Maintenance Improvement
- 2015
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this research work is to explore and describe human factors affectingmaintenance execution. To achieve the purpose of this study, the influencing factors have been identified using a literature survey. They have been categorized into four main groups namely organizational, workplace, job and individual factors. The Analytical Hierarchy Process (AHP) method is employed on data questionnaires to rank the priority of the factors. The interrelationships between these factors have been recognized by theInterpretive Structural Modelling (ISM) model. In the present case studies, MICMAC1analysis technique is also implemented for identifying the driving, dependent, linkage and autonomous factors. The data was collected through a questionnaire survey involving the participation of 16 and 25 maintenance staff and 10 mining experts in Swedish and Iranian mines, respectively. Within the study, it has been identified that the temperature, work layout, tools design and tools availability are the most important factors in both mines related to these categories. However, the significant factors in the organizational and individual categories are different in the selected mines. The effect of workplace factors on the maintainability of mining equipment is discussed and thereafter a methodology for maintainability management in the design and operation phases is developed. In the thirdcase study HEART2 is applied to estimate the probability of human error occurring duringmaintenance execution in an Iranian cable company. This research supports maintenance management to gain knowledge of human factors that affect maintenance execution. Further, this understanding could be useful in the development of strategies to improve the execution of maintenance.Keywords: Human Factors, Maintenance Management, Human Reliability, HumanPerformance, AHP, ISM, MICMAC, HEART

The (in)effectiveness of financial incentive on fertility behaviour : Childcare –a safety net for children?
- 2017
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Is childcare a safety net for vulnerable children? This paper investigates the role of childcare for the health outcomes of children whose parents are unemployed. Exploiting time variation in childcare access resulting from a reform requiring Swedish municipalities to provide childcare also for children with unemployed parents, we estimate causal effects on health, as measured by register data on hospitalizations. We find that access to childcare reduced hospitalizations for infections among toddlers, especially among boys. Among children in preschool age access to childcare caused a temporary increase in hospitalization for infections the year they got access to childcare.

Intention recognition in human machine collaborative systems
- 2007

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Robotsystem har använts flitigt under de senaste årtiondena för att skapa automationslösningar i ett flertal områden. De flesta nuvarande automationslösningarna är begränsade av att uppgifterna de kan lösa måste vara repetitiva och förutsägbara. En av anledningarna till detta är att dagens robotsystem saknar förmåga att förstå och resonera om omvärlden. På grund av detta har forskare inom robotik och artificiell intelligens försökt att skapa intelligentare maskiner. Trots att stora framsteg har gjorts då det gäller att skapa robotar som kan fungera och interagera i en mänsklig miljö så finns det för nuvarande inget system som kommer i närheten av den mänskliga förmågan att resonera om omvärlden. För att förenkla problemet har vissa forskare föreslagit en alternativ lösning till helt självständiga robotar som verkar i mänskliga miljöer. Alternativet är att kombinera människors och maskiners förmågor. Exempelvis så kan en person verka på en avlägsen plats, som kanske inte är tillgänglig för personen i fråga på grund av olika orsaker, genom att använda fjärrstyrning. Vid fjärrstyrning skickar operatören kommandon till en robot som verkar som en förlängning av operatörens egen kropp. Segmentering och identifiering av rörelser skapade av en operatör kan användas för att tillhandahålla korrekt assistans vid fjärrstyrning eller samarbete mellan människa och maskin. Assistansen sker ofta inom ramen för virtuella fixturer där eftergivenheten hos fixturen kan justeras under exekveringen för att tillhandahålla ökad prestanda i form av ökad precision och minskad tid för att utföra uppgiften. Den här avhandlingen fokuserar på två aspekter av samarbete mellan människa och maskin. Klassificering av en operatörs rörelser till ett på förhand specificerat tillstånd under en manipuleringsuppgift och assistans under manipuleringsuppgiften baserat på virtuella fixturer. Den specifika tillämpningen som behandlas är manipuleringsuppgifter där en mänsklig operatör styr en robotmanipulator i ett fjärrstyrt eller samarbetande system. En metod för att följa förloppet av en uppgift medan den utförs genom att använda virtuella fixturer presenteras. Istället för att följa en på förhand specificerad plan så har operatören möjlighet att undvika oväntade hinder och avvika från modellen. För att möjliggöra detta estimeras kontinuerligt sannolikheten att operatören följer en viss trajektorie (deluppgift). Estimatet används sedan för att justera eftergivenheten hos den virtuella fixturen så att ett beslut om hur rörelsen ska fixeras kan tas medan uppgiften utförs. En flerlagers dold Markovmodell (eng. layered hidden Markov model) används för att modellera mänskliga färdigheter. En gestemklassificerare som klassificerar en operatörs rörelser till olika grundläggande handlingsprimitiver, eller gestemer, evalueras. Gestemklassificerarna används sedan i en flerlagers dold Markovmodell för att modellera en simulerad fjärrstyrd manipuleringsuppgift. Klassificeringsprestandan utvärderas med avseende på brus, antalet gestemer, typen på den dolda Markovmodellen och antalet tillgängliga träningssekvenser. Den flerlagers dolda Markovmodellen tillämpas sedan på data från en trajektorieföljningsuppgift i 2D och 3D med en robotmanipulator för att ge både kvalitativa och kvantitativa resultat. Resultaten tyder på att den flerlagers dolda Markovmodellen är väl lämpad för att modellera trajektorieföljningsuppgifter och att den flerlagers dolda Markovmodellen är robust med avseende på felklassificeringar i de underliggande gestemklassificerarna.

Kvinneforskningspolitiske (pr)øvelser
- 1999
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Målsettingen for licentiatuppsatsen er å analysere nordisk kvinneforsknings formuleringer av forskningspolitiske felter, problemstillinger og utfordringer, og gjennom kontakt og diskusjon bidra til samarbeid, diskusjoner og offentlighet om forskingspolitikk i kvinneforskning. Arbeidet har tatt utgangspunkt i relativt nytt materiale fra Danmark, Norge og Sverige. I kap. 1 presenteres prosjektet, problemstillinger og materiale. Kapitlene 2-6 består av innledninger og artikler holdt eller skrevet i løpet av de to senaste åren. Diskusjoner om kjønn og akademia står i fokus i kap. 2 - "Universities have politics". I kap. 3, artikkelen "Gamle og nye drømmer", diskuteres et kvinneforskningspolitiske intervensjonsprosjekt som blev utført for en del år tilbake, og det antydes noen nye omdreiningspunkter for et slikt arbeid. Enkelte perspektiver utdypes i kap. 4, "Kvinneforskningens samfunnskontrakt", hvor termen "kvinneperspektiv" som forskningspolitisk term granskas krtitiskt. De to siste kapitlene tar utgangspunkt i den norske forskningsmeldingen som kom våren 1999. Ut fra tre lesestrategier forsøkes det leses muligheter for kvinneforskningspolitiske strategier. Det ses også på innholdet i regjeringens forskningspolitiske verdidebatt, og det diskuteres mulige intervensjoner i denne ut fra feministiske vitenskaps- og teknologistudier.
