Analysis and Proposal for Increased Capacity at a Surgery Unit - More capacity, same resources
Get PDFThe main purpose of this project was to provide Sahlgrenska University Hospital with suggestions for increased capacity with their current resources. The study was conducted at Östra Sjukhuset, Operation 1. The theory used is based on the principles of operations management by Holweg et al. (2018) and research suggests that reducing non-surgery time and variation in surgery processes provides significant impact on time saved, and ultimately increased capacity. Through observations, a work sampling study and collection of historical data from their internal software, Orbit, it was possible to build an empirical foundation of the current state, the division of labor and surgery data. Connecting the literature review and our results to the case of Operation 1 resulted in the main recommendation of parallelization of the anaesthesia process. This is done by implementing an anaesthesia induction room such that instrument preparations can continue in parallel. The potential improvement for one of the studied surgery types was 55 minutes, which is roughly 50% of the non-surgery time. From observations and the work sampling, potential reductions of variation and wastes could be identified which in turn result in a potential 68 additional minutes saved per day. Further, it was recommended that all recommendations should be combined with a continuous improvement strategy of standardizing specific surgery types to specific weekdays. With the implementation of these process improvements, it is possible to achieve enough spare capacity to perform an additional surgery in the same day and theatre. Therefore, yes, it is possible to increase capacity with the same amount of resources
Venture Capital - En studie om hur geografiskt ursprung påverkar sannolikheten för en exit
Get PDFBakgrund - För att kunna bygga långsiktigt hållbara företag är det viktigt att nystartade
företag har möjlighet att få kapital. Många gånger är det svårt för de nystartade bolagen
att få in tillräckligt med kapital då investeringarna kan betyda en stor risk för
investerarna. På grund av detta har Venture Capital investeringar, det vill säga
investeringar inom Private Equity gjorda vid ett tidigt skede i nystartade företag en
viktig roll. VC-firmorna bidrar inte bara med kapital till de nystartade bolagen utan
dessutom med kunskap och övervakning.
Problem - De som investerat i de nystartade företagen vill ha en avkastning på sina
investeringar. Den avkastningen kan realiseras genom att göra en exit, som innebär att
investerarna säljer sin del av bolaget. Tidigare studier har visat på att geografiskt
avstånd samt ursprung påverkar VC-firmans aktivitet i det nystartade bolagets styrelse. I
denna studie har det undersökts om detta även påverkar sannolikheten för en exit.
Syfte - Studiens syfte var att undersöka huruvida VC-firmornas geografiska ursprung, i
relation till portföljbolagen, har haft någon inverkan på sannolikheten för en exit.
Metod - Studien har genomförts med en deduktiv metodansats. Det innebär att
vedertagna teorin använts för att sätta upp hypoteser som sedan testats. Studien är
genomförd som en kvantitativ studie där data samlats in från databaser och sedan har
resultatet tagits fram med hjälp av statistiska verktyg.
Resultat och slutsats - Studien har visat på att det geografiska ursprunget för VC
påverkar sannolikheten för en exit. När det gäller exits ökar utländskt VC sannolikheten
för en exit. Resultatet visade sig vara detsamma för datasetet som enbart innehåller
IPO:s. Däremot så var inte resultatet från M&A:s statistiskt signifikant. Därför har det
inte bevisats att sannolikheten för en M&A påverkas av geografiskt ursprung
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
