The aim of my study is to investigate how last year students in upper secondary schoolunderstand certain mathematical concepts, in particular the unit circle and its trigonometry.I have used intentional analysis to interpret student?s actions when they solve certain tasks onthe basis of a cognitive, situated and cultural context.Interviews with four university teachers in mathematics about the unit circle, trigonometry,and mathematical understanding, serve both as background for the study and as basis for adiscussion, where I relate students understanding to what the teachers want new students toknow about these concepts when they begin university studies in mathematics.The students were arranged in three groups with three students in each group. Each group waspresented with two tasks, one in which they were asked to calculate the cosine values for onepointed, one blunt and one straight angle, each located in a separate triangle. They were alsoasked to decide whether the points (0,71; 0,71) and d (1 2 , 3 2 ) are located on the unit circleor not.My conclusion is that students mainly have an operational conception of the unit circle andtrigonometry. The lack of structural conceptions result in difficulties in seeing connectionsbetween the concepts in unfamiliar situations.

Information overload is by no means a new concept, but has come to prominence the last decade. A generally accepted definition of the phenomenon does not exist. The main question in this master thesis is how to define information overload in order to create a connotative concept for information science. This thesis reviews the nature and causes of information overload, and considers possible solutions, both individual and technical, and their relevance to the information professional. The review of the results shows that researchers seldom or never give a legible definition of what the concept information holds.

Efter Kuwaitkriget 1991 har Kina påbörjat att modernisera sin försvarsmakt därinformationsteknologin fått en ökad betydelse. Informationsteknologin har medfört ett ökatkinesiskt intresse för informationsoperationer som ett sätt att angripa en motståndares system.Syftet med denna uppsats är att lägga en grund för fördjupad kunskap kring Kinas syn på ochförmåga till informationsoperationer och informationskrigföring, samt att inom dessaområden speciellt belysa CNO. Detta för att få en insikt i Kinas militära upprustning.Metoden som används för att analysera detta är att genom textanalys jämföra kinesisk ochamerikansk krigföringsförmåga inom informationsoperationer i allmänhet och CNO isynnerhet. Teoriansatsen för jämförelsen bygger på den svenska ?Pelarmodellen? somanalysverktyg för krigföringsförmågan.Resultatet visar på att det finns likheter mellan USA och Kina, men att det också finnsavgörande skillnader.

Den 1 juli 2010 avskaffades värnplikten i förmån för ett yrkesförsvar, varpå premisserna för utbildningen av soldater förändrades. Idag har män och kvinnor från 18 år möjlighet att genomföra s.k. Grundläggande Militär Utbildning (GMU) under tre månader på frivillig basis. De nya premisserna kan m.h.t. frivilligheten ställas i paritet med civil vuxenutbildning, där båda upplever exempelvis avhopp till följd av motivationsbrist.Syftet med studien är delvis att identifiera officerarnas upplevda utmaningar på GMU avseende rekryternas tidigare erfarenheter, motivation samt lärarrollen.

The object with this work was to create a simple feeding program for beef cows. Another object was that I could learn more about the properties and functions of Excel and Visual Basic. I used parts of a program I designed a few years ago. This old program was neither user friendly nor had it an appealing layout. Initially I decided how I wanted the new program to appear and on which foundation it should be built. I designed various forms into a spread sheet, such as lists and multiple choice buttons. Using VBA (Visual Basic for Application) I could create macros, which used the information chosen in the lists and with the multiple choices to calculate the feeding requirement or the feeding plan.

It seems like Swedish municipalities are dominated by beliefs that all citizen participation is good for the development of local democracy. A critic of this certainty is rising among Swedish scholars of political science. However, a critic with an ambition of such generalization is harsh. Different democratic projects contents different qualities and thereby diverse problems in the democratic process. If these democratic problems within the process can be recognized, a deeper understanding can be found and in the prolongation a strengthening of the democracy.This essay examines the democratic process of Lomma municipality's democratic project of citizen participation.

In our attempts to understand the world, wildlife films play a significant role. Wildlife films help us to see new places and learn about animals in remote locations, that we otherwise wouldn?t be able to do. Yet wildlife films have throughout history been criticized, mainly for the ambivalent relationship between science and storytelling. While the films give us a scientific impression and say something about the ?reality?, they clearly have the intension to amuse, capture and entertain their audience.

Huvudsyftet med denna uppsats är att visa på hur olika atmosfärsförhållanden kan påverka dettaktiska utnyttjandet av elektromagnetisk vågutbredning och behovet för en operatör att kunnaförstå och bedöma denna påverkan.Sensorer som använder det elektromagnetiska spektret utnyttjas mer och mer i våra militärasystem. Vädret och atmosfären påverkar transmissionen och vågutbredningen avelektromagnetiska vågor. Olika atmosfärs- och väderfenomen påverkar sensorernas frekvenseroch våglängder och skapar begränsningar i utnyttjandet. Utnyttjandet av sensorer och systemför att upptäcka och följa mål och hot kräver kunskapen att kunna bedöma hur sensorn ochsystemet påverkas när de används i olika klimat och väderförhållanden. Behovet av detta ärstort och kommer i framtiden att öka då vi mer och mer förlitar oss på tekniska hjälpmedel föratt kunna upptäcka och bekämpa mål i en stridsmiljö.

This study investigates the potential of a rhetorical theory of knowledge to expand beyond its own domain and into political theory, specifically theories of deliberative democracy. Despite the increasing interest in communication in democratic theory in the last decades, the majority of theorists have not turned their interest towards rhetorical science. On the contrary, theorists often regard rhetoric as dangerous and incompatible with the deliberative ideal of reason. The aim of this study is therefore to defend rhetorical science by investigating how the rhetorical theory of knowledge ? as it is presented by Chaïm Perelman and Oldbrecht Tyteca, and further developed by Mats Rosengren and Maria Wolrath Söderberg ? can contribute to the understanding of deliberative democracy.

The purpose of our research is to study how guidance counseling initiated by the students themselves differs between girls and boys in high school. We want to study if there are any differences between girls and boys regarding guidance initiated by the students themselves. We conducted a quantitative survey consisting of a questionnaire survey with 125 respondents. The respondents are second year students at the Science program. The result of the survey shows that there are hardly any differences between girls and boys regarding guidance initiated by the students themselves.

Informationsoperationer utgör idag en allt viktigare del i svenska internationella uppdrag. Inom informationsoperationer sorterar funktionerna Psykologiska operationer (psyops) och Civil-Militär samverkan (CIMIC). Enligt grundsynen för informationsoperationer skall CIMIC utgöra en stödfunktion åt psyops under internationella insatser. Dock är inte samarbetet mellan parterna närmare preciserat och beskrivet i Försvarsmaktens dokumentation. Syftet med uppsatsen är att beskriva och analysera hur funktionen psyops inom Försvarsmakten kan stöttas av stödfunktionen CIMIC vid en internationell insats.För att uppnå syftets ambition använder uppsatsen sig av en deskriptiv metod i syfte att empiriskt beskriva funktionernas karaktärer och egenskaper.

The 17th October 2014 the Swedish Armed Forces (SwAF) introduced an intelligence operation in Stockholm archipelago after receiving credible observations regarding illegal underwater activities. Following the data collection and associated analysis it could be stated with certainty that a foreign submarine had violated the Swedish territorial waters. Media depend on SwAF to provide them with accurate information due to the confidentiality in these matters and the general area of investigation is therefore how the actions of the Swedish Armed Forces, in the submarine incident 2014, were portrayed in the Swedish media. Newspapers and blogs of defense policy represent the media and the thesis is based on the theories constructed by Graham Allison, the rational actor, organizational behavior and governmental politics. Furthermore, it is relevant to examine if there are any similarities or differences in how the submarine incident is illustrated, and what may be the reason for any possible occurrences.
