A qualitative case study has been conducted about the management and use of operating instructions in a process plant in Sweden. The work was inspired by Dekker's notion of two paradigms in relation to procedures, where Model 1 is authoritarian and top-down, and Model 2 is flexible and consultative (Dekker, 2003). The results support Dekker's hypothesis, that organizations should strive to

I april 2021 drog debatten om mäns våld mot kvinnor igång ordentligt när fem kvinnor inom loppet av tre veckor mördades av närstående män. Det allmänna intresset för mäns våld mot kvinnor gjorde också att nätverket “Gömda kvinnor” fick ökad uppmärksamhet. Dessa våldsutsatta kvinnorna lever med skyddad identitet och gömda i Sverige för att inte hittas av sina före detta män, några har till och med

På avloppsreningsverk (ARV) som tillämpar kväverening är den vanligaste tekniken nitrifikation följt av denitrifikation. Denna process kräver omfattande luftning, vilket både är elintensivt och minskar mängden biogas som kan utvinnas. Anaerob ammoniumoxidation (anammox) är en alternativ reningsmetod som minskar luftningsbehovet genom att nitrit används som elektronacceptor istället för syre i oxidIn wastewater treatment plants (WWTP) which implement nitrogen removal, the most common process is nitrification followed by denitrification. This requires extensive aeration which comes at a large energy cost while at the same time reducing biogas potential. Anaerobic ammonium oxidation (anammox) is an alternative treatment process that requires significantly less aeration by using nitrite as an

Syfte: Syftet med studien är att bidra med kunskap för forskningsområdet om hur företag i revisionsbranschen använder sig av kommunikation i sociala medier. Frågeställning: Hur använd

Construction sites are key points regarding implementing robot supervision to create more secure, reliable, and free hand-work workspaces. This project’s scope is to develop a complete interpretation of a modern concept of surveillance. For this case, the test scenario is the industrial lab at the Faculty of Engineering, Lund University, known as RobotLab. For its development, an Augmented Reality

For many decades, Sweden has been famous for its ambitious investments in active labour market policy programs, particularly in different types of wage subsidies/subsidy programs. There are important characteristics distinguishing the programs, but they have in common that the hiring company receives a substantial subsidy from the Public Employment Service (PES) for hiring either long-term unemplo

The routing of a delivery fleet is a classical optimization problem, known as the vehicle routing problem (VRP), which can heavily impact the quality of a logistic distribution process. Historically, the VRP formulation has mainly included internal combustion engine vehicles (ICEVs). However, due to their reduced environmental impact, the inclusion of electric vehicles (EVs) has become more popula

Syftet med denna studie är att undersöka i vilken utsträckning kapitalstrukturen för bolag inkluderade i aktieindexet Standard & Poor ́s 500 kan förklaras med hjälp av variabler relaterade till bolagens styrelse och vd. Studien bygger på en kvantitativ undersökningsmetod och antar en deduktiv ansats för att utröna hur styrelsens sammansättning och vd:ns egenskaper påverkar valet av kapitalstruThe purpose of this study is to investigate to what extent the capital structure of companies in the stock index Standard & Poor ́s 500 can be explained through variables related to the board and CEO of the company. The study applies a quantitative method of study and uses a deductive approach to determine how board composition and CEO characteristics affect the choice of capital structure. A

The many-body problem is one of the most challenging problems in physics due to the complexity emerging from the interactions of many quantum particles. Since the advent of computers with increasing power, computational methods have been very successful in providing insight and precise solutions to this problem. We give an introduction to two canonically used methods, density functional theory and

As the world moves more and more towards automation of repetitive and dangerous tasks there are still many tasks that primarily involve interaction with an object that are still carried out by humans. This is in many ways due to difficulties in programming the robot to achieve similar performance. The most natural way of transferring these skills to the robot is by demonstration. This can be achie

Image feature extraction has become a key technology in the field of autonomous Artificial Intelligence. The algorithm Oriented FAST and Rotated BRIEF (ORB), uses established technologies in image processing to allow a computer to ”see” and navigate its surroundings. This process, however, is very performance intensive, but a field-programmable gate array (FPGA), a programmable semiconductor devic

We study the problem of reducing polarization (variance) of opinions at stationarity in a directed weighted graph with node set divided into two groups: stubborn, initialized with a fixed opinion and regular who repeatedly update their opinion to the average of their out-neighbors, known as the DeGroot model with stubborn nodes. We show how the polarization can be minimized for a number of simple

Bakgrund och problem: Belöningssystem är ett av de styrmedel som kan användas inom ekonomistyrning, detta innebär att organisationens ledning använder olika belöningar för att motivera sina anställda till att arbeta på det sätt som är mest fördelaktigt för organisationen. Individanpassade belöningssystem kan vara en utmaning för organisationer i och med att motivation skiljer sig mellan olika indi

This empirical study attempts to assess the use of French (and other languages) within a European institution to illustrate the following: the daily practical French used within a single directorate-general, the awareness at the directorate of how France is trying to increase the use of French especially during the French presidency 2022, and the attitude and use of French inside and outside the w

Småskalig plattform för upprening av monoklonala antikroppar Utvecklingen av en uppreningsplatform för antikroppar visar en 30% ökning i produk-tivitet med hjälp av parallella flödesbanor. Det är nu också möjligt att upprena ännu fler prov per körning än tidigare. Utvecklingen av nya antikroppar blir allt mer viktigare i dagens samhälle för att kunna förbättra vår analytiska och diagnostiska föThe aim of this project is to transfer and implement a monoclonal antibody purification process that is traditionally done on an ÄKTAxpress to another machine called the ÄKTA pure. This is due to the fact that the ÄKTAxpress is being discontinued by the manufacturer and a replace-ment machine is needed for the time being. The project will include developing some new meth-ods that might also highli

Background: Psoriatic arthritis (PsA) is an inflammatory joint disease occurring in up to 30% of psoriasis patients. Relatively few clinical trials assess PsA treatment and data presentation in these are far from uniform making comparisons difficult. Objectives: To perform a literature review on methotrexate (MTX) efficacy in PsA. Research questions were: What evidence support MTX monotherapy in

Evidensparadigmet har sedan 80-talet varit rådande inom psykologin som vetenskap och praktik. Kritiker till evidensparadigmet menar emellertid att den positivistiska forskning, framförallt RCT-studier, som bedrivs inom paradigmet vilar på antagandet som inte överensstämmer med den psykoterapeutiska praktiken. Syftet med föreliggande studie var att, genom kvalitativ metod, jämföra hur ett urval av The evidence paradigm has dominated the field of psychological practice and research since around 1990. Critics however, have adressed the research-practice gap, suggesting that the positivistic research, such as RCT-studies, conducted within the paradigm are based on assumtioms that are ill fitting with the reality of clinical practice. The aim of the present study is, using a qualitative method,
