Background: The incidence of detected ductal carcinoma in situ (DCIS) continues to increase and now accounts for 14% of all breast cancer, and 20%–25% of screen-detected cases. Treatment trends of DCIS are important in order to inform the ongoing debate about possible overdiagnosis and overtreatment, but have not been investigated for over a decade in Australia and New Zealand. Against this backgr
From November 12th to 13th in 1872, an extreme coastal flood event occurred in the south Baltic Sea. An unusual combination of winds created a storm surge reaching up to 3.5 m above mean sea level, which is more than a meter higher than all other observations over the past 200 years. On the Danish, German, and Swedish coasts, about 300 people lost their lives. The consequences of the storm in Denm
The effectiveness of health promotion for community-dwelling older people is well documented; however, there is a general lack of health economic evaluations. The aim of the present study was to evaluate long-term cost-effectiveness over 4 years of two health promoting interventions: senior meetings and a preventive home visit, for community-dwelling older people in relation to no intervention. We
Topology optimization is a mathematical tool for finding optimal distributions of material phases within a design domain. It is commonly used in early design stages to generate conceptual structural layouts. Ultimately, designs generated by topology optimization consist of distinct material phases with enhanced performance. Most research on topology optimization methods focuses on linear elastic m
The research questions that motivates this study are about the attitudes and practices of students, academic researchers and professors with respect to the file-sharing website Sci- Hub. Previous research on Sci-Hub and file-sharing has confirmed there is still a lack of understanding of Sci-Hub use and users and more insight is required to help solve the problem of illegal file sharing. This stud
All humans are unique, we have different characteristics and we make different decision. This is a challenge when it comes to modelling human behaviour. The models we design are based on mathematics where there is no room for inconsistencies such that are present in human behaviour. So how do we account for this when we try to model human behaviour in evacuation modelling? Most models provide the
Denna fallstudie syftar till att utvinna fördjupad kunskap om mellanchefens komplexa och mångtydiga roll som meningsskapare och meningsgivare under en digitaliseringsförändring. Tidigare forskning har nämligen betonat mellanchefens roll som avgörande under en förändringsprocess. Detta eftersom mellancheferna innehar en roll som meningsskapare när de omvandlar övergripande organisationsinformation The purpose of this case study is to gain a deepened knowledge about the middle manager's complex and ambiguous role as sensemakers and sensegivers during a digital change. Former research has emphasized the middle manager’s role as crucial during a process of change. This because the middle managers hold a role as sensemakers when they convert the organizational information to their own units
The aim of this Master's thesis is to investigate the choices that legal deposit libraries in Sweden make, during the process of collecting and displaying printed ephemera. The word “ephemera” originally derives from a Greek word simply meaning “short-lived” or “lasting only for one day”. The term “printed ephemera” thus refers to a wide range of different documents meant to be discarded after
The Church of Sweden is marginalized in society and the membership of the Church is decreasing, which means that the church's economy is on the decline, but the demands on the Church by its members have not decreased. This is a comparative study that deals with the roles of deacons and priests and their contribution to the Church. The aim is to get an overview of similarities and differences i
Sammanfattning Hemlig rumsavlyssning är exempel på statens tvångsmakt gentemot den enskilde. Det kan åsamka betydande skada i enskildas personliga integritet men är trots det ett viktigt och slagkraftigt element, i polisens brottsutredande verksamhet. Hemlig rumsavlyssning intar en särställning bland de hemliga tvångsmedlen, då omfattande uppgifter rörande enskildas privatliv insamlas. Utöver uppgSummary Secret coercive measures such as bugging, is an example of the state's coercive power over the individual. It may cause great damage to the personal integrity of the individuals but is nonetheless an important and powerful element, in controlling and solving serious criminal activity. The use of bugging is particularly intrusive, since extensive information concerning the privacy of i
Bakgrund: Manligt kön och hög ålder har visat sig utgöra riskfaktorer att återinläggas på IVA. Att implementera uppföljande verksamhet efter utskrivning, såsom PIG-team, kan bidra till att identifiera patienter som riskerar att försämras i sitt sjukdomstillstånd eller återinläggas på IVA. Tillämpandet av bedömningsinstrumentet NEWS har visat sig kunna identifiera patienter som löper risk för oplanBackground: Male sex and older age have been described as risk factors for readmission to the Intensive Care Unit [ICU]. The implementation of PIG-team can help to identify patients who are at risk for clinical deterioration or being readmitted to the Intensive Care Unit. The usage of National Early Warning Score [NEWS] has been proven to effectively discriminate patients who are at risk for unpla
Behovet av avancerad rening genom till exempel ozonering eller aktivt kol på avloppsrenings-verk blir tydligare i världen som följd av höga uppmätta nivåer av läkemedelsrester i recipienter. I länder som Schweiz är implementeringen redan idag lagstadgad och också i Sverige förväntas inom en överskådlig framtid krav införas på avlägsning av organiska mikroföreoreningar från avloppsvatten. I dagslägThe need for advanced wastewater treatment using for example ozonation or activated carbon is becoming exceedingly apparent because of high measured concentrations of pharmaceutical res-idues in recipients all over the world. In Switzerland for example there is legal requirements for the implementation of advanced treatment and within the foreseeable future also in Sweden the demands on the remova
Title: Spheres of Influence - Exploring the impact of different ownership structures on the cost of debt. Purpose: The purpose of this study is to investigate whether sphere ownership influences the cost of debt for Swedish firms, and if the effect can be explained by different types of sphere ownership, such as family, institutional, or bank-affiliated spheres. Methodology: To investigate the r
The overall purpose of this thesis is to investigate the feasibility of producing electrofuels from CO2 and H2 in connection to a CHP plant equipped with carbon capture technology. This is done by investigating the production of e-methane, e-methanol and e-kerosene from captured CO2 and H2 produced from electrolysis. Each of the processes is designed and analyzed in Aspen HYSYS. From this, the ene
This literature study aims to investigate prior knowledge of the effects of heavy metals on amphibians in freshwater environments. The methodological approach for the study is based on extensive searches in the database called Web of Science. These searches then gets narrowed down with the help of with strategic search words for the subject at spotlight. The final combination of searched words, to
As we know our population keeps growing and our cities are getting denser, urban sprawl is a phenomenon that affects a big part of our society. Research has shown that urban sprawl lacks consideration for human interactions and has an absence of proper urban planning. Multiple types of barriers have made it more and more difficult to create a sense of community within this environment. Moreover, d
One of the main qualities of life in Icelandic society is the earth’s heat that has been harnessed and fed into the homes of the citizens. The swimming pool is the clearest and most visible manifestation of these qualities of life. Bathhouses are a regular part of many people’s daily lives, and human life in the pools is a fascinating part of Icelandic society. Architecture plays a key role there,
Anomaly detection is important in many different areas, among them web security. When performing anomaly detection in web security there can be hundreds of features in the collected web traffic data to consider, even though all of them might not be necessary. This thesis aims to develop a strategy to dynamically create significant parameter groups from web traffic data containing over 100 features
