Intranät En kommunikationskanal för alla?

Intranet is today a common technical groupware to communicate in many organisations. People can interact through the Intranet and communicate within the organization and get relevant information according to their workplace. It can be difficult to get everybody to use the Intranet as an information- and communication tool. This causes problems when people want to reach out with information. With these thoughts we entered our work at Luftfartsverket at Arlanda airport.

Utveckling av försäljnings- och leveransmodell

The objective of this work was to evaluate and implement a number of energy saving functions for a specific embedded system. The functions were then grouped into a number of energy levels with known properties in terms of functionality, energy consumption, and transition time between the levels.The embedded system consisted of an AT91 ARM9 processor, GSM/GPRS modem, display, Ethernet and other peripheral units. Some energy saving methods that were considered were suspend to RAM, suspend to disk, frequency scaling, and methods for saving energy in the modem, Ethernet, USB and display backlight. The functions were grouped into levels and an interface was specified for controlling the energy level.It proved possible to get known properties within the defined energy levels, even though the paritioning of functions into these levels proved to be sub-optimal in a typical application usage scenario because it was designed for mainly energy consumption, not usage.The final result is a number of energy saving functions grouped into levels, which are controllable via an application interface. Each of the levels have a known energy consumption in both loaded and un-loaded mode..

GPU accelerated SPH simulation of fluids for VFX

Fluids are important to the Visual Effects Industry but extremely hard to control and simulate because of the complexity of the governing equations. Fluid solvers can be divided into two categories, those of the Eulerian point of reference and those of the Lagrangian. Both categories have different advantages and weaknesses and hybrid methods are popular. This thesis examines Smoothed Particle Hydrodynamics, a Lagrangian method for physically based uid simulations. To allow the artist the exibility given by shorter simulation times and increased number of iterations, the performance of the solver is key.

Ökad kollagring i boreal skog : Kan blädningsbrukad skog lagra mer kol än trakthyggesbrukad skog?

This study was conducted to test the hypotheses that a forest managed by selective cutting can store more carbon than a forest managed by clearcutting. The study was carried out as a meta-analysis. The data that was found was analyzed by performing t-tests on the proportional effect that the two silvicultural methods had on the driving factors of CO2-efflux and carbon stores in coniferous boreal forest. In all areas tested, an effect in favor of selective cutting was found, but not all of them significant however. The soil respiration following selective cutting was significantly lower than that of clearcutting, and the primary production of a clearcut area cannot according to reason exceed that of an area post-selective cutting.

Vilka är problemen för elever med matematiksvårigheter?

Vilka är problemen för elever med matematiksvårigheter? (What are the problems for students with mathematical difficulties)? Skolutveckling och ledarskap, Specialpedagogisk påbyggnadsutbildning, Lärarutbildningen, Malmö Högskola. Syftet med mitt examensarbete är att undersöka vad elever med matematiksvårigheter tycker är svårt i matematik samt hur de tycker en bra undervisning i ämnet skall se ut. Jag tittar även på vilka arbetssätt och undervisningsmetoder deras lärare/speciallärare använder sig av. I mitt arbete har jag gjort både en enkätundersökning bland elever i år åtta samt intervjuer av lärare. Med hjälp av kvalitativa intervjuer av skolans matematiklärare/speciallärare har jag tagit reda på hur de planerar och genomför sin undervisning. Resultaten av min undersökning pekar på, att det råder en samsyn bland skolans lärare och speciallärare hur lektioner skall planeras och genomföras för att nå bästa resultat. Men de saknar tid och fortbildning för att klara av en mer varierad undervisning där den muntliga kommunikationen är viktig.

Den ensamma flatan och glitterbögen : En kvalitativ studie av hbtq-personers porträttering i tre olika kvinnomagasin

The aim of this studie centers on how lgbt (lesbian, gay, bisexual, transgender) are portrayed in women?s magazines. The magazines we have chosen to analyze are FRIDA, VeckoRevyn and amelia, which all three have different target groups. We have, with the assistance of the rhetorical and semiotic analysis methods, assessed 18 articles with their associated photographs. These methods are part of the qualitative analysis model and are used in order to study less empirical data with more depth.

Elevers inställning till matematik : - en jämförande studie av elevers uppfattning av matematikämnet och matematikundervisningen

Based on earlier experiences of mathematics and mathematical learning, both as a student and as a teacher, I became more and more interested in how well the publicly accepted opinions about mathematics as an uninteresting, difficult and ?geeky? subject corresponded to reality. What do Swedish pupils really think about mathematics and is it possible to identify any differences in their attitudes based on the pupils? age?From this point of view the following questions were formulated:·What are pupils? attitudes towards mathematics in grades 3, 6 and 9 and how do they conceive their learning conditions?·Is it possible to detect any differences in the attitudes and preferences depending on the pupils? age?The result of this study compares well with previous studies done in this and overlapping fields and indicates that:·Younger pupils tend to have a better liking of mathematics but with increasing age that interest fades out.·Most pupils, without regard to age, consider mathematics to be one of the most important subjects, despite the fact that many pupils also find mathematics difficult and boring.·For pupils of all ages, the teacher is the most important factor in the learning process. Older students have more specific demands on the teacher for knowledge and pedagogical skills.·A high noise level, talking and disturbances in the classroom are the most bothering elements when it comes to learning mathematics.

Tidig läs -och skrivinlärning : Intervjuer med pedagoger om deras syn på lärande

The purpose of this work is to explore how to work with early reading and writing and find out what really comes first of the two. The work also involves the best known literacy learning methods and deals with methods to work around reading and writing. I have read previous research on the subject and watched a movie from our AV-central on children?s early language development. It includes an interview with two professors of education, Mats Myrberg and Mats Ekholm where they talk about the pros and cons of early learning literacy. My research is based on literary sources and interviews with educators who work with reading and writing in the early years. The results showed that even if a teacher tries to work with early writing skills we still remain in the traditional school, beginning with learning how to read.

Efficient treatment of adolescents with behavioural problems

The purpose of this essay is to investigate which components previous scientific studies suggest that an efficient treatment for adolescents with behavioural problems should contain. For this purpose, an extensive review of scientific research conducted in Scandinavia has been read and will be presented in this essay. This essay also present an introduction to residential care in Sweden as well as to an alternative form of treatment for adolescents with behavioural problems called Multidimensional Treatment Foster Care (MTFC). The result of this essay suggest that treatment of adolescents with behavioural problems should be based on the emphasis of risk/resilience factors of the youth and that the treatment should be adapted to the youth?s individual personality and way of learning.

Kunskap, motivation och stöd : En studie om kompetensutveckling inom statistisk analys av experimentella stöd

Testing and analysis of measurement data is a major part of the workday for development engineers within the section Fluid and Emission Treatment to assure the quality of products developed by Scania CV. The ineluctable variation and therefore uncertainty of results can be quantified and discussed with the use of statistical methods.The overall objective of this study is to examine how the competence of development engineers can be improved within the area of statistics. This has been done by relating the concept of competence with the use of statistical methods to analyse experimental data and by investigating which factors that influence the competence of the engineers. Observations of the daily operations, interviews and a focus group with development engineers and a workshop with management personnel, has been used as research methods in this study.The results show that the desired competence, from the perspective of the individual, consists of knowledge, motivation and support. It is important that none of these parts are neglected when the competence of engineers is to be strengthened.

Vidden av kommunikationsförmågan i matematikundervisningen : En studie av problemlösningsmetoder med elever i år 3

Bakgrund: I grundskolans läroplan synliggörs tydligt att eleven i matematikundervisningen skall utveckla olika förmågor och att dessa är centrala. En av dessa är kommunikationsförmågan, som är särskilt betydelsefull genom att den sammanlänkas till alla de övriga, såsom de som gäller representation, resonemang och problemlösning. Av denna anledning har kommunikationsförmågan i matematik och medvetenheten kring och utvecklingen av denna hos lärare och elever undersökts i denna studie. En grundförutsättning är att individuell färdighetsträning i lärobok är otillräckligt. Elever bör tidigt få möjlighet till exempelvis arbete i grupp med ett matematiskt problem, då de i tal och skrift kommunicerar matematiska begrepp och metoder.

Anestesi och intensivvårdssjuksköterskans hantering av mekanisk ventilation : - en litteraturstudie om minskning av atelektasbildning och förebyggande av komplikationer

Background Atelectasis is a commun respiratory complication related to general anesthesia and may contribute to pneumonia and acute respiratory failure. Atelectasis apear within 10 minutes after anesthetization and occur in 90% or more anesthezied patients regardless of age and gender. The aim of this study was to indentify if there are any evidence for which methods are ultimate or are most efficacious to reduce and prevent the formation of atelectasis.                                                                                                          Methods This study is a descriptive litterature study where 28 scientific studies have been indentified for review and analysis.                                                                                                               ResultsThe use of 100% oxygen during the induction of anesthesia favors the developement of atelectasis. This can be prevented by preoxygenation with oxygen content of 100% combined with a PEEP of 6-10 cmH2O. When free airway is secured, oxygenation with 100% was found to be unnecessary.

Hur man kan introducera och integrera nyanlända barn i skolan : En jämförande undersökning mellan två skolors verksamhetsformer och de riktlinjer som högre instanser anger

Purpose: Our purpose with this study is to compare how the two selected schools in two different areas in Stockholm chooses to introduce and integrate newly arrived children in Sweden. The schools are located in the suburb and downtown in Stockholm. One school has chosen to integrate the child by placing him or her in a preparatory class and the other school is placing the child into a regular class.Investigation questions: We want to find out how the choosen schools are working with a newly arrived child. How is the child integrated and introduced directly into a regular class through teaching methods and teaching material and how a newly arrived child is integrated and introduced into a preparatory class through teaching methods and teaching material. We also want to find out if the community authorities in the City of Stockholm and the Swedish state have guidelines that schools are supposed to follow in the work with newly arrived children and whether our selected schools are working after these guidelines.Method: The study is based on two methods.

Att få vara med och skriva manus : Att motverka traditionella könsroller genom dramapedagogik i förskolan

The purpose of this thesis is to study how preschool teachers can reach the goal of the swedish educational plan to prevent traditional gender roles for children ages 3-6 through drama in education.This is answered by four hypothesis based on Judith Butler's queer theory, George Herbert Mead's social psychological theory and Gavin Bolton and Dotothy Heathcotes drama pedagogical theories. The hypotheses are tested against four teachers' examples of their work.The hypotheses areHypothesis 1: By using the expert's mantle and active observation in teacher-in-role indrama educational exercises, we can see how the children internalize the heterosexualmatrix and the outline of the internalized other.Hypothesis 2: By using the "mistakes" that occur when children repeat performativeacts that do not fit with the heterosexual matrix, these other possible behaviors can bestrengthenedHypothesis 3: Through drama exercises that are not normative teachers can widen theheterosexual matrixHypothesis 4: Through drama pedagogical methods like teacher-in-role teachers canprovide possibilities of other performative acts and the creation of a more tolerantinternalized other.The analysis show that the respondents work within all these hypotheses in different ways and thathypotheses 2 is the one with the weakest support in the interwievs. The examples are also weakregarding the use of Boltons drama pedagogical methods, but that there are a number of othermethods in use.Some of the conclusions are that more theoretical knowledge in the preschool drama pedagogics tocounteract traditional gender roles and patterns, as well as the drama of educational theory need tobe linked to queer and social psychology research. There is also no monitoring of the long term effects of the work..
