Genom fallet QlikTech ger denna uppsats en aktuell inblick i hur kunskapshantering kan hanteras i en kunskapsintensiv kontext. Medarbetare har i dag möjligheter att samarbeta inom olika interaktiva digitala miljöer för att hitta och dela med sig av kunskap och erfarenheter. Denna uppsats fokuserar på att undersöka hur digitala Communitys uppkommer, växer fram och integreras för att uppnå global kunskapsdelning inom organisationer. Detta ses som en framgångsfaktor för att ta vara på kunskapsintensiva utvecklingsföretags kretivitet och innovationskraft.Genom ett tolkande tillvägagångssätt, analyseras åtta semistrukturerade kvalitativa intervjuer med medarbetare på QlikTech för att undersöka hur olika informationssystem används för att stödja olika kunskaps- och kollaborationsprocesser. Intervjuerna kompletteras med observationer and dokumentanalyser för att nå djupare insikter.Resultaten tyder på att användare använder system med fördefinierade strukturer för att dokumentera officiell kunskap, och system med framväxande strukturer för informell dialog och samarbete. Olika system kompletterar varandra, då kunskap förs över mellan system. Gräsrotsinitierande informationssystem kompenserar för glappet mellan officiella IT-implementationer och sociala kommunikationsbehov.Teknologi och praktik utvecklas hand-i-hand. Då diskussioner, idéer, perspektiv och kontext kan upprätthålls i emergent social software platforms, t.ex. Salesforce.com, kan komplext problemlösande underlättas i datorstött samarbete. Dessa plattformar minimerar glappet mellan den formella och sociala kommunikationen inom communities of practice, vilket ger förutsättningar för organisatorisk lärande.På QlikTech växer digitala communitys fram organiskt över tid. Organisationer använder data- och text mining och relaterade teknologier för att brygga fragmenterade communitys för att uppnå kapacitet att nå isolerade kunskapskällor genom sökning. Organisationer kan lägga till sociala lager över dessa fragmenterade back-end-system, designade för att bilda övergripande gränssnitt mot användare som underlättar samarbete och driver på innovation inom arbetsplatsen. / This thesis provides contemporary insights how knowledge management can be approached by a knowledge-intensive organisation. Knowledge workers today have unprecedented means to collaborate in different spaces of knowledge sharing. By analysing the case of QlikTech, results indicate that knowledge management is an integral part of knowledge-intensive organisations.By adapting an interpretive approach, eight semi-structured qualitative interviews with employees at QlikTech are analysed to find out how different information systems support different knowledge and collaboration processes. The interviews are complemented by on-the-job observations and analysis of documents to reach deeper understanding.Results indicate that users use systems with predefined structures to document official knowledge, and systems with emergent structures for informal dialogue and collaboration. Different systems complement each other, as knowledge is transferred between systems. Grass root initiated information systems compensate for the gap between official technology implementations and the social communication needs.Technology and practice co-evolve. As discussions, ideas, perspectives and context can be sustained in emergent social software platforms, such as Salesforce.com, complex problem-solving can be enabled in computer-supported cooperative work. These platforms minimise the gap between the formal and social communication within communities of practice, which facilitates organisational learning.At QlikTech, digital communities emerge organically over time. Organisations can use data and text mining, natural language processing and information extraction technologies to bridge fragmented communities to gain the capabilities to access dispersed knowledge sources through search. Organisations can add a social layer of these fragmented back-end systems, designed for building cross-functional employee-facing communities that drive collaboration and accelerate innovation in the workplace.

The aim of this study is to explore how three Swedish media outlets adhere to mass media logic and social media logic in articles on their websites and the corresponding Facebook posts on their Facebook pages. The media outlets are SVT (Sveriges Television), Dagens Nyheter and Expressen. They represent a public service broadcaster, a daily newspaper and a tabloid in a Swedish context. The samples of the study consists of the headlines and leads of the articles and the text in the corresponding Facebook posts. The articles and the corresponding Facebook posts cover the news event of the Russian invasion of Ukraine on the 24th of February 2022. The samples are analysed with the method of critical discourse analysis and the theoretical frameworks of mass media logic and social media logic. The main findings of this study are that the samples adhered to the mass media logic elements of coverage of events, staging experts and media personalities; and the social media logic elements relating to connectivity. The further implications of this study may be that media as an institution is impacted by social media platforms, such as Facebook, and that news distributed on Facebook is adapted to the platform. The findings of this study are an example of how media outlets in Sweden adhere to mass media logic and social media logic, when covering a news event in articles on their websites which they share on their Facebook pages.

Urban warfare is unfortunate reality of the modern world and that fact is unlikely to change in the near future. One significant danger to soldiers in an urban setting is posed by concealed snipers. The large amount of cover among densely packed buildings make snipers hard to detect by sight or sound. When a sniper fires at troops, it is imperative to positively locate the sniper as soon as possible to ensure the safety of soldiers in the field. One method of sniper detection is the use of distributed sensor nodes. These nodes may be stationary, mounted on a soldier or mounted on a vehicle. These nodes may accommodate many types of sensors, including microphones and cameras, both conventional and infrared. This project specifically deals with microphone arrays and conventional cameras mounted on a remote-operated vehicle. The purpose of this project is to demonstrate that mobile sensor platforms can be used alone or in groups to locate the source of gunshots as well as other sources of noise. The vehicle described is a recreational ATV. It has been outfitted with mechanical actuators and electronic control modules to allow the vehicle to be operated remotely. The selection and installation of these components is detailed. This includes the control of the ATV's steering, brakes, throttle and engine starter. The system also includes a failsafe circuit to ensure that the system will shut down if positive control is lost. An array of sensors and transducers was added to the vehicle to allow for useful data collection. This includes the aforementioned microphone array and camera. Other sensors mounted on the vehicle include a GPS antenna and an electronic compass for establishing the position and orientation of the vehicle and an accelerometer to sample engine vibration and allow for cancellation of engine noise. Once assembled, this vehicle was tested in laboratory and field environments to demonstrate its effectiveness as a mobile sensor platform. The tests showed that a microphone array could be used in combination with a camera to provide a continuous stream of images of a moving target. The test also demonstrated how a mobile acoustic node can relocate to triangulate the location of an acoustic source and thereby replicate a larger stationary network. Overall, these tests demonstrated that such a system is a feasible platform for urban combat use. Full implementation would require the fusion of several separate features, the addition of a few new features, such as semi-autonomous operation, and further field testing. / Master of Science

This thesis examines the handling of racial issues in United States political party platforms from 1964 to 2016. The primary objective of this study is to analyze how the two major political parties, the Democratic Party and the Republican Party, have approached issues of race in their platforms. To accomplish this, a content analysis was conducted on the platforms of both parties during this time period. Each reference to race in the platforms was categorized as either "acclaim," "defend," or "attack." "Acclaim" refers to statements that praise racial progress or advocate for policies that benefit marginalized communities. "Defend" refers to statements that seek to justify the party's position on race or defend racial issues, while "attack" refers to statements that criticize the other party's position or policies related to race. The study reveals that the parties have used different strategies to address race. This research is important because it sheds light on the ways in which the two major political parties have addressed one of the most significant issues facing the United States. The findings provide insight into the ideological differences between the parties and offer a historical perspective on the evolution of racial politics in the United States. This research is relevant for scholars and policymakers interested in understanding the role of race in American politics, as well as for activists and advocates seeking to influence policy outcomes related to racial justice.

Yes / There is increasing evidence that the Cloud Computing services have become a strategic direction for governments' IT work by the dawn of the third-millennium. The inevitability of this computing technology has been recognized not only in the developed countries like the UK, USA and Japan, but also in the developing countries like the Middle East region and Malaysia, who have launched migrations towards Cloud platforms for more flexible, open, and collaborative public services. In Jordan, the cloud-based e-government project has been deemed as one of the high priority areas for the government agencies. In spite of its phenomenal evolution, various governmental cloud-based services still facing adoption challenges of e-government projects like technological, human-aspects, social, and financial which need to be treated and considered carefully by any government agency contemplating its implementation. While there have been extensive efforts to investigate the e-government adoption from the citizens' perspective using different theories and models, none have paid adequate attention to the security issues. This paper explores the different perspectives of the extent in which these challenges inhibit the acceptance and use of cloud computing in Jordanian public sector. In addition to examining the effect of these challenges on the participants’ security perception. The empirical evidence provided a total of 220 valid responses to our online questionnaire from Jordanian citizens including IT- staff from different government sectors. Based on the data analysis some significant challenges were identified. The results can help the policy makers in the public sector to guide successful acceptance and adoption of cloud-based e-government services in Jordan. / Mutah University - Jordan

The proliferation of open-source software development platforms has given rise to various online social communities where developers can seamlessly collaborate, showcase their projects, and exchange knowledge and ideas. GitHub stands out as a preeminent platform within this ecosystem. It offers developers a space to host and disseminate their code, participate in collaborative ventures, and engage in meaningful dialogues with fellow community members. This dissertation embarks on a comprehensive exploration of various facets of software development communities on GitHub, with a specific focus on innovation diffusion, repository popularity dynamics, code quality enhancement, and user commenting behaviors. This dissertation introduces a popularity-based model that elucidates the diffusion of innovation on GitHub. We scrutinize the influence of a repository's popularity on the transfer of knowledge and the adoption of innovative practices, relying on a dataset encompassing GitHub fork events. Through a meticulous analysis of developers' collaborative coding efforts, this dissertation furnishes valuable insights into the impact of social factors, particularly popularity, on the diffusion of innovation. Furthermore, we introduce a novel approach to computing a weight-based popularity score, denoted as the Weighted Trend Popularity Score (WTPS), derived from the historical trajectory of repository popularity indicators, such as fork and star counts. The accuracy of WTPS as a comprehensive repository popularity indicator is assessed, and the significance of having a singular metric to represent repository popularity is underscored. We delve into the realm of code quality on GitHub by examining it from the perspective of code reviews. Our analysis centers on understanding the code review process and presents an approach rooted in regularity to foster superior code quality by enforcing coding standards. In the concluding phase of our research, we investigate the intricacies of communication within technology-related online communities. Our attention is drawn to the impact of user popularity on communication, as elucidated through an examination of comment timelines and commenting communities. To contextualize our findings, we compare the behavioral patterns of GitHub developers and users on other platforms, such as Reddit and Stack Overflow.

This study analyses the impact emerging platforms for housing allocation might have on the Swedish housing market, through an analysis of allocation platforms and housing queues. The study utilises Fields and Rogers’ (2021) typology of operational and data platforms in order to define and analyse the practices of municipal housing agencies, marketplaces for rental housing, and assistants for managing housing queues, as allocation platforms. Characteristic of allocation platforms, defined within the framework of platform real estate (PRE), is engagement in data collection and valuation. Combining housing applicants’ ‘übercapital’ (Fourcade & Healy, 2017) with queue times creates what I term queue capital. This queue capital serves as a dual process of data-valuation, that allows for valuation of rental housing according to queue time, but also enables housing seekers to access rental housing. Furthermore, housing queues are categorised as strict or indicative based on the rental policies of housing companies: strict queues, commonly used by municipal housing agencies, prioritise the first eligible applicant, whereas indicative queues, prevalent in marketplaces, organise applicants without strictly adhering to queue order.

This thesis explores how journalists and managers at Nordic public service organizations perceive successful news reporting through third-party social media. The aim is to contribute to the understanding of digital platform dependencies among public service organizations. Previous research has conceptualized digital journalistic epistemologies and examined specific methods of news production on platforms, highlighting concerns about journalistic autonomy in spaces influenced by third-party interests. This thesis employs a qualitative, exploratory approach to investigate the social media strategies and understandings of success at Nordic public service media organizations YLE, SVT, NRK, RÚV, and DR. Through semi-structured interviews, the study reveals an ongoing negotiation between editorial objectives and platform logics in social media news reporting. Journalists view success as engaging with the target audience, while managers emphasize credibility and relevance in a shifting media landscape. Further, the perceptions of journalists and managers are compared, highlighting a possible negotiation between the managerial and operational levels. The study revisits public service media news-making in a Nordic context, contributing to the fields of digital journalism studies and digital platform studies.

In this work, we focus on two attractive crowd-based business models, i.e., user-generated content creation and freight-matching long-haul trucking. First, as elaborated in CHAPTER 2, we consider a game theoretical modeling approach for understanding the operation of non-profit UGC platforms that rely on users to create content and maintain financial sustainability. In particular, we examine several interesting research questions with practical importance and unique contributions to the literature. These research questions mainly investigate how changes in critical business factors influence the platforms' strategic effort allocation, user participation, and overall performance. Second, in CHAPTER 3, we focus on the flourishing freight-matching businesses that rely on crowdsourced drivers for long-haul trucking. In particular, although the practice suggests that shippers' ordering behaviors of freight-matching services may remarkably impact crowdsourced drivers' bidding behaviors, the literature has yet to examine this issue formally. Therefore, we collect industrial data and construct a strict empirical schema for understanding the association between shippers' order timing and freight-matching performance. Besides, by deliberately building a theoretical modeling framework and using a data-driven estimation of model parameters, we are able to simulate the freight-matching performance of adopting our empirical findings and evaluate the practical value of our study. By investigating these two prominent business models, we aim to understand the advantages of crowdsourcing businesses and the role of crowds in nowadays' business innovations. Besides, we also provide valuable managerial insights for business runners who are interested in this "young" market of crowdsourcing businesses. / Business Administration/Strategic Management

No. of bitstreams: 1 Rodrigo de Farias Julião.pdf: 2312669 bytes, checksum: cbb55dd1bc3b181dd07ac7d4d1da85ab (MD5) Previous issue date: 2018-05-03 / A presente tese tem como objeto de estudo o amparo legal da saúde do trabalhador offshore, através da análise interdisciplinar do Anexo II da Norma Regulamentadora n°30; de Convenções Internacionais da Organização Internacional do Trabalho e do Sistema da Occupational Health and Safety Assessment Series 18001:2007. O estudo aborda os tipos de plataformas, como se estrutura o trabalho offshore na Bacia de Campos (RJ); os principais acidentes no passado e como se encontram, atualmente, as condições de trabalho e segurança nas plataformas e os problemas físicos, emocionais e profissionais do trabalhador das plataformas. A tese também apresenta a atuação da Agência Nacional de Petróleo, Gás Natural e Biocombustíveis na prevenção de acidentes. Apesar de existirem normas nacionais e convenções internacionais, direta ou indiretamente, para garantir a segurança quanto ao ambiente de trabalho nas plataformas, elas não são efetivamente aplicadas pelas empresas offshores, o que se torna também um fator passível de comprometer a saúde do trabalhador e necessitar de normatização efetiva. / The purpose of this thesis is to study the legal protection of the health of offshore workers through the interdisciplinary analysis of Annex II of Regulatory Norm 30; International Conventions of the International Labor Organization and the Occupational Health and Safety Assessment Series 18001: 2007. The study addresses the types of platforms, how to structure the offshore work in the Campos Basin (RJ); the main accidents in the past and how are currently working conditions and safety platforms and the physical, emotional and professional problems of the workers of the platforms. The thesis also presents the performance of the National Agency of Petroleum, Natural Gas and Biofuels in the prevention of accidents. Although there are national norms and international conventions, either directly or indirectly, to ensure safety in the work environment on the platforms, they are not effectively enforced by offshore companies, which is also a factor that could compromise workers' health and necessitate of effective standardization.
