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.

Education in Swedish sport is mainly based on traditional learning that requires a lot of time and effort, which could be a barrier for trainers since they report a lack of time as a consequence of their commitment as a leader. The Swedish sports movement has noticed some trends that could be seen as influential on the future directions of sport. One of these trends is a changing way of communication where people today communicate to a greater extent with the use of digital technology. The Swedish sports movement has to relate to this and follow the evolution. The use of e-learning has increased in higher education and organizations over the past decades.

Intercropping involving trees is called agroforestry and makes it possible to get higher production for every area unit. The trees can function as food, fodder, fuel, medicine; prevent mark erosion and much more. Agroforestry can also be combined with animal husbandry. The aim of this study was to document the animal production systems used by rural small-scale farmers maintaining ruminants and using agroforestry in the northern province of Rwanda. The farmers using agroforestry is expected to have higher milk yield than average due to homegrown protein. The method used during the study was semi-structural interviews with booth open and closed questions. In order to get in contact with farmers that matched the criteria; small-scaled rural farmers with ruminants and using agroforestry, the ?Vi Agroforestry Programme? (Vi-Life) in Kigali were contacted and the staff worked as supervisors, translators and contact with the farmers throughout the study. During the study nine individual farmers, two cooperatives breeding sheep and one group interview were conducted.

This report documents the development of a software system for automaticscheduling called Hazel. This system is comprised of a server where an automaticscheduler has been implemented, as well as a web and mobile applicationthat allows users to interact with the system. The scheduler hasbeen developed with the functional programming language Haskell and usesa SAT-solver.Manual scheduling has long been the bane of managers everywhere, asmatching the needs of the employer with those of the employee is often adifficult and time-consuming task. There already exists several automaticschedulers that attempt to solve this problem. The issue with said schedulersis that thay tend to be expensive, or developed to only fulfill the needsof a particular organisation.

SammanfattningDatum: 18 januari 2013Nivå: Kandidatuppsats i företagsekonomi, 15 hpInstitution: Akademin för hållbar samhälls- och teknikutvecklingFörfattare: Simon Brodahl Pontus Eliasson David WahlbergTitel: Jag är organisationenHandledare: Johan GrinbergsNyckelord:Delaktighet, engagemang, delaktighet i beslutsfattande frågor, psykologiskt ägandeskap, anställdas välbefinnande och kunskapsspridning.Frågeställning:- Finns det ett gemensamt synsätt på delaktighet och engagemang inom ABB Motors & Generators?- Vad kan göras för att öka delaktigheten och engagemanget inom produktionsdelen och vad kommer detta leda till?- Vad bör ABB: Motors & Generators ha i åtanke vid applicerandet av delaktighet inom produktionsdelen i framtiden?Syfte: Syftet är att utifrån teoretiska referenspunkter analysera ABB:s verksamhet ur ett engagemangs- och delaktighetsperspektiv som ligger till grund för en analytisk diskussion vilken utmynnar i förbättringsförslag.Metod: Den teoretiska referensramen är konstruerad med hjälp av vetenskapliga artiklar och litteratur som behandlar ämnet engagemang och delaktighet. Det empiriska materialet består av en kvalitativ studie bestående av tre djupintervjuer.Slutsats: ABB Motors & Generators innehar ett tankesätt som behövs för att främja ökad delaktighet och engagemang hos de anställda.

In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

To read and understand are essential competences for everyone in our society; at the same time reading comprehension among Swedish pupils is on the decline. The Swedish school must therefore try to improve their instructions to increase the students' reading comprehension. The aim of the study was to describe how three reading comprehension strategies, if possible, could improve the reading comprehension for the students, including children with learning disabilities, when reading texts of natural science in a third-grade class. The three strategies that were introduced were: to activate prior knowledge, to structure information and to record contents. The questions of the study were: How are the three strategies introduced in the classroom? Can the children with learning disabilities see any benefits for their reading comprehension when working with the strategies? How do the children with learning disabilities experience working with the strategies? Can the teacher see any benefits when working with the strategies? Is it possible to see any differences among the students' results, before and after completed intervention? Method: The results have been collected through observations and qualitative interviews, which make this a qualitative study.

In order to evaluate the benefits and costs associated to investments in information technology (IT) managers need to be aware of the complexity in the nature of the task. Hence all the benefits that arise from the investment are not of pure economic character. The complexity of the task is even more obvious when managers also need to prioritize between a number of possible investments in order to fit a given budget.Stora Enso Skog AB is about to implement a new administration system to the organisation and due to that they will also implement a new standard system for the production planning process. In order to seek the modifications in the standard system that needs to be done to fit the organisations way of working, the managers have put together a reference group to seek out these modifications.The aim with this report is to identify a model that can prioritize these suggested modifications and test it practically with a group of future system users. The first part of the report is a literature study to map the existing models that are available.

The visions of the United Nations concerning sustainable development and conservation of biodiversity can only be realized if the human population succeeds in creating coexistence between human and wildlife. Landscape architects are able to influence on how landscapes are to be maintained and developed. The negative impact of infrastructure on wildlife has become a critical problem in Sweden and other parts of Europe. Wildlife crossings has been developed as a solution for the problems of road barriers in the landscape. The crossings are made to give animals a better opportunity to cross roads.

Organic agriculture is financially promoted in Sweden by special environmental support and as consumers we are all encouraged to buy organic food. At the same time scholars at the Swedish University of Agricultural Sciences claim that organic farming does not provide any environmental benefits. The main criticism is that organic farming has lower yields than conventional, which means that more land is needed to produce the same amount of food as in conventional farming, leading to deforestation and loss of biodiversity. As for climate change, the critics claim that the significantly higher productivity in conventional crop production compared to organic, releases surplus land, which could be used for bio-fuel production and thereby replace the fossil fuels. The critics also claim that organic farming causes higher nutrient leaching than conventional.

In this essay a model of a potential illegal hunter?s decision-making is created and presented in order to provide an overview of important parts of the complexities associated with the current Swedish predator policy. A comparison is made between a livestock owner?s economic incentives, and the expected costs faced by the potentially caught lawbreaker. In accordance with economic theory the benefits and costs of illegal hunting are compared and thus the optimal choice is determined where marginal costs and benefits are equal.

Problem: The authors have, during the process of development of this thesis, tried to create an understanding of how a number of organizations, all working with different approaches around the ?brand Sweden?, perceive the efficiency and benefits of using extended concept around embassies as a tool in their strategic work. The embassies in question have an evolved concept in the sense that they don not only hold a traditional political and legal role. The problem facing us authors was the issue whether theses embassies are efficient arenas to coordinate the forces and resources of the organizations concerned, in the mission to enhance the visibility and awareness of Sweden abroad.Purpose: The purpose is to describe the strategic work with marketing Sweden to be able to look in to whether the evolved concept behind the embassies in question are used as a tool in within the work of the organizations. We wish to research this to be able to evaluate if this arena is perceived as efficient for the organizations concerned.Method: In order to get a background to which one establish and communicate a nations brand the authors have studied literature within the subject.

The high and seemingly increasing degree of consumer avoidance and disliking of television advertising breaks should raise many questions for commercially financed television networks as it can be argued that benefits sought by both viewers [seeking a fulfilling viewing experience] and advertisers [seeking advertising effectiveness] are eroded by this effect. This thesis studies effects on advertising effectiveness [RecallBRAND; AttitudeBRAND; AttitudeAD] as well as on the viewing experience [SatisfactionPROGRAM/CHANNEL; Attitude PROGRAM/CHANNEL; IntentionPROGRAM/CHANNEL] given a reduced degree of advertising clutter. By conducting an experiment two breaks are compared, one having the standard primetime nonprogram time units (5 min and 30 sec *3?16minutes/hour) and the other the standard nonprogram content cut in half (2.45 min *3 ?8min /hour).Results show that the reduced breaks award advertisers with higher commercial effectiveness. Measures of RecallBRAND demonstrates no differences between the standard and the reduced break, implying a significantly increased likelihood to be recalled and an equivalently lowered risk to be forgotten in the reduced break.

Syftet med magisteruppsatsen var att undersöka vilka effekter införandet av RR 29? Ersättningar till anställda? och IAS 19 ?Employee benefits? har haft på de företag som valt att tillämpa någon av rekommendationerna i förtid. RR 29 är en direktöversättning av IAS 19 och vi har därför valt att studera rekommendationerna som ett gemensamt begrepp. En kvalitativ metod valdes för att få fram de tidiga effekterna av införandet RR 29/IAS 19. Effekterna undersöktes utifrån två olika delstudier.

Social media has recently expanded dramatically, as more people are using different media such as blogs, Facebook and Twitter, to express their opinions. This increases the possibilities to spread information and an unclear legal regulation in this area can create adverse consequences. Freedom of expression is a constitutional right, which forms an important cornerstone of a democratic society. Public employees? freedom of communication means that they can submit information to the media, without fear of reprisals from the authorities.
