This research overview examines what research says about upper secondary school students' difficulties with complex numbers. The three main areas covered are general difficulties with complex numbers, how to teach the subject, and whether the history of complex numbers can be beneficial in this teaching. A historical deep dive into the history of complex numbers is also included to further investigate this idea. The results show that upper secondary school students struggle with complex numbers in various ways. The name of the subject creates a negative connotation, as it is initially perceived by students as fictional and complicated. Furthermore, a consequence of the inherently abstract nature of complex numbers is that gaining a comprehensive understanding of them is challenging.

The aim of this report is to examine the possibilities to use network theories to perform vulnerability analysis on complex networks. The scoop of this work is also to improve the possibilities to chart, analyze and present the vulnerability in a power grid. In this report it has been, using power outage statistics, possible to verify, that network theories can be used to evaluate the vulnerability of an infrastructure network. However further studies to establish values on how vulnerable a network is are needed..

The response to many on-going or emerging conflicts since the beginning of the 21st century has been different forms of multinational complex peace operations. Civil-military relations are a commonly studied field that traditionally has its focus on nations. This study intends, in the context of organisations, to test the correlation between a civil-military approach and outcome in complex peace operations. A hypothesis has been deduced from researcher Robert Egnell?s theory on complex peace operations, that states that: UN peace operations with an integrated civil-military approach are more successful in achieving their goals than peace operations with a divided approach.

Lund who has over 90 systems in 12 departments and now wants to streamline the management of these IT systems. Governance of IT systems is something that Lund would treat as it carried a large amount of changes in their practices, where the control is something missed in trying to standardize their systems. What's missing for Lund Municipality is routine to fall back on in order to streamline the management when they get into these complex situations.Given that Lund treat so many systems make it so that the situation quickly becomes very complex due of the organization's structure. The municipality is divided into twelve departments that have their own goals, it is an organization that is organized, which makes creating standards become complicated when all departments have different needs. Our study was based on a framework that deals with complex environments that lack a clear definition.An analysis was conducted where we started from the theory associated with the interviews conducted in which we aimed to understand their decision and understand the processes that affect system development.

This essay is about Late Iron Age settlement and its production. I want to define the nature ofthree different workplaces on Bornholm, Denmark, and compare them. My aim is to see if itis possible to define a workplace through the traces of the craftsmanship. Several materials areselected in this essay and the analysis provides different perspective on workplaces in the LateIron Age in Scandinavia. The results of the analysis between the three workplacesAgerbygård, Baggård and Kanonhøj shows that Baggård have more traces of melting of bronsthan any other of the places.

Two ecological models of nitrogen processes in treatment wetlands have been evaluated and compared. These models have been implemented, simulated, and visualized in the Modelica language. The differences and similarities between the Modelica modeling environment used in this thesis and other environments or tools for ecological modeling have been evaluated. The modeling tools evaluated are PowerSim, Simile, Stella, the MathModelica Model Editor, and WEST. The evaluation and the analysis have been performed using McCall?s factors for software quality (McCall et al, 1977), a correlation analysis and the Constant Comparative Method (Glaser&Strauss, 1999).

Problem: The corrugated board industry is highly affected by customer uncertainty, various demands and short delivery times. In combination with a complex multi-step production process managers have to be able to identify bottle-necks and gain knowledge and understanding of how different changes in process will affect the production output. <br/><br/>Purpose: The purpose of this master thesis is twofold, (1) to examine applicability of complexity theory through agent-based modelling on a production process (2) to identify improvement areas in order to increase the production output at SKS production site in Eslöv, by modelling and simulating the production process through an agent-based model. <br/><br/>Method: The chosen method of this study is a combination of a case study and a complex system approach. The empirical data was collected through interviews, observation and document studies which were analysed through an agent-based simulation model.

In media the debate about discipline and order in school is widely heard. A politician, some teacher or a representative from the teacher´s union, most often speaks these words. The interest for these issues seems to be persistent.This study is primarily about the expression ?discipline and order?. The aim is to find out how the expression ?discipline and order? is used in the investigated material.

The purpose of this essay is to analyze the EU discourse in the Swedish media. The questions that the analysis seeks to answer are; what image of EU is portrayed in the Swedish media? To which degree does the EU discourse fulfill media?s ?news values?? And what are the potential effects of the discourse on EU?s reputation? After several demarcations, I chose 8 articles form Sweden?s four largest newspapers to base the analysis on.    The theoretical and methodical structure behind this analysis is the theories and practices of Fairclough?s critical discourse analysis. Added to the theoretical structure are also theories about reputation and theories about news values. The method used in the analysis is a modified version of Fairclough?s three-dimensional model of critical discourse analysis.

This essay focuses on the film Joker (2019) directed by Todd Phillips. It examines the narration and the use of music as a narrative device to discuss questions about identification and perception through close textual analysis. The aim is to research this in combination with the film?s complex storytelling and unreliable narration. The essay use several narratological and psychological theories as well as psychopathology.

The purpose of this study is to investigate how the process and result of renovations in socioeconomic vulnerable areas affect the residents' right to housing; with a focus on women's experiences of their homes, their area, the housing company's apartment renovations. The study is conducted through two research questions: How do the women in L?vg?rdet experience their homes and the area? And how do the women in L?vg?rdet experience the process and the result of the renovations of the rental apartments? The methodology used is qualitative research interviews. The empirical material was gathered through qualitative interviews. Eight women living in L?vg?rdet have been interviewed.

The Swedish museum world is a complex and disputed field. Changes are high on the agenda, but they are neither easy nor self-evident. This master thesis looks at how Swedish museum professionals discuss changes and how they envision museum work for the future. It is also an analysis of the current state of the field. We have made a critical discourse analysis of three recent projects; Svåra saker, Museum 2000, makten.nu and the debate articles from the journal Svenska Museer from 2000 to 2001.

Issue of study: The development of technology and society is closely linked. Mutual dependency and complex interrelationships make straightforward analysis of issues regarding the future of technology and society hard to perform. Therefore, the study addresses the question of how organizations should describe and analyze the interactions of technology and society in order to gain a better understanding of what the future may bring. Purpose: ? To develop a method for analysis of the future course of issues regarding technology and society in interaction.? To apply and test the developed method through a case study, where it is used to analyze the future of the Russian fuel market.

Between 1965-1974 one million new flats were produced in Sweden and the project is called the millionprogramme. One of the areas that was build during this period of time is Rosengård in Malmoe. Today Rosengård is a very segregated area, not just in relation to the city of Malmoe, but within itself. I´ve chosen to study the ideologies behind one of the actors acting and non acting regarding the segregation complex of problems in Rosengård, the housemanagers. I´ve studied one public housecompany and two houseassociations who all owns and manages houses in Rosengård.The ideologies that I´ve studied in this study is what the informers think of the people that live in Rosengård, the society in general, Rosengård and the diffrent smaller areas within Rosengård.
