Data kvalité i gränssittet mellan industriel tillverkning och machine learning
No full textInnovations are coming together and are changing business landscapes, markets, and societies. Data-driven technologies form new or increase expectations on products, services, and business processes. Industrial companies must reconstruct both their physical environment and mindset to adapt accordingly successfully. One of the technologies paving the way for data-driven acceleration is machine learning. Machine learning-technologies require a high degree of structured digitalization and data to be functional. The technology has the potential to extract immense value for manufacturers because of its ability to analyse large quantities of data. The author of this thesis identified a research gap regarding how industrial manufacturers need to approach and prepare for machine learning technologies. Research indicated that data quality is one of the significant issues when organisations try to approach the technology. Earlier frameworks on data quality have not yet captured the aspects of manufacturing and machine learning as one. By reviewing data quality frameworks, including machine learning or manufacturing perspectives, the thesis aims to contribute with an area-specific data quality framework in the interface of machine learning and manufacturing. To gain further insights and to complement the current research in the areas, qualitative interviews were conducted with experts on machine learning, data and industrial manufacturing. The study finds that ten different data quality dimensions are essential for industrial manufacturers interested in machine learning. The insights from the framework contribute with knowledge to the data quality research, as well as providing industrial manufacturing companies with an understanding of machine learning data requirements
Maturity assessment of value creation and continual learning : A study of internal development in the private service sector
No full textBakgrund: En kund köper inte varor och tjänster som inte skapar något värde, vilket är något företagen på marknaden måste ta hänsyn till. Utöver det är företagens mål att nå finansiella samt icke-finansiella vinningar från sin produkt. Det är stor konkurrens på marknaden vilket innebär att konsumenten kan välja och vraka något som företagen måste anpassa sig till. I tjänstesektorn är det kunskap som är den viktigaste faktorn för att locka till sig kunder och är på så sätt något tjänsteföretagen ständigt måste arbeta med om de skall överleva på marknaden. För att undersöka detta kommer företagens syn på värdeskapande, kontinuerligt lärande och de egna resurserna studeras i uppsatsen. Syfte: Att undersöka hur tjänsteföretag arbetar med värdeskapande, kontinuerligt lärande samt dess nedlagda resurser inom ramen för internt utvecklingsarbete. Vidare är syftet att jämföra tjänsteföretagens mognadsgrader med varandra för att därigenom se vilka skillnader samt var potential till förbättring finns. Metod: Uppsatsen grundar sig i den kvalitativa ansatsen med ett heremeneutiskt förhållningssätt. Den sekundärdata som samlades in var genom vetenskapliga artiklar, internetkällor och böcker. Fyra företag och fem personer deltog i uppsatsen vilka intervjuades genom en semi-strukturerad intervjuguide. Datainsamlingen analyserades med hjälp av ett organisatoriskt IQ-test. Resultat och slutsats: Företagen har en liknande grundsyn i sättet de tänker på värdeskapande och kontinuerligt lärande. Dock visar empirin att företagen skildje sig i konflikthanteringen samt att några av företagen hade svårigheter att förändra sig på lokal nivå eftersom de agerade på en global marknad. För att uppnå ett värdeskapande och kontinuerligt lärande lägger samtliga företag ner mycket resurser för att erbjuda en tjänst som möter kundens behov och krav. Hur mognadsgraden för värdeskapande och kontinuerligt lärande ser ut skiljer sig mellan företagen eftersom företagen var bra på olika saker. Det är även inom dessa områden potential till förbättring finns. Uppsatsens bidrag: I sin helhet ger uppsatsen en ökad kunskap om hur tjänsteföretag i den privata tjänstesektorn arbetar med värdeskapande och kontinuerligt lärande. Därutöver bidrar uppsatsen med ytterligare kunskap inom vilka områden tjänsteföretagen utmärker sig, deras mognadsgrad i värdeskapande och kontinuerligt lärande samt var det finns potential till förbättring.Background: Customer do not intend to purchase a product or service that does not provide them with value and this is something that companies have to consider. At the same time companies aim to achieve financial or non-financial profits by selling their products or services. The market is very competitive and ultimately it is the consumers who have the power to pick and choose whatever alternative that fits them best. Hence, this is something companies have to take into consideration. The private sector provides services rather than products and it is this which is used to attract customers and therefore something companies continually have to work with in order to survive in the market. In order to investigate this, different companies’ view of value creation, continual learning and resources have been studied. Aim: To investigate how service companies work with value creation, continual learning and utilized resources (within the range of internal development work). The aim is also to compare company’s level of maturity and suggest where improvements can be made. Methodology: The study is qualitative with a hermeneutic approach. Data were collected from scientific articles, internet sources and books. Four companies and five persons in total participated in the study and were interviewed using a semi-structured interview form. The data was later analyzed with the help of an organizational IQ-test. Results and conclusion: Companies often have a similar ethos in the way they think about value creation and continuous learning. However, the empirical data shows that companies differ in regard to conflict management, as well as some of the companies having difficulties in making changes at the local level because they act in a global marked. In order to achieve value creation and continuous learning all the companies use a great deal of resources to meet the needs and demands from customers. However, the maturity level of value creation and continuous learning look different between various companies because the companies are good at different activities. It is in these areas there lies the potential for improvement. Contribution of the thesis: It provides increased knowledge in how the private service sector works with value creation and continual learning. It also provides further knowledge of how the service sector excels, its maturity grade in value creation and continual learning, and how they can improve
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
