Ungdomar och social integration i Malmö: En kvantitativ och kvalitativ studie om ungdomars upplevelser av och syn på social integration i deras vardag

This paper examines, through questionnaire, how young students in upper secondary school in Malmo experience social integration. It also contain what they think should be done in order to improve the integration between youth that are ethnic Swedish and youth that have a foreign background. To understand the subject we started with a review over Swedish integration politic and its influence over Malmo and social integration in the country. We have used such theoretical starting points as identity and ethnicity in relations to the social surroundings, social affinity theory and flexible mindedness, making of groups among youth and factors to promote social integration. Our conclusion is that the experience of social integration between the two groups depends on how you experience yourself.

Hållfasthetsegenskaper i gjutjärn : tensile properties of cast iron

In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of cast iron, cast under different metallurgical conditions.Four different series of cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.

Effektiv betong för småhusproduktion : Betong med högt luftinnehåll för platta på mark

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

Förbättra leveranssäkerhet mot kund : En utredning för att göra tillverkningsprocessen enklare, rakare och stabilare

Det är vanligt att Svenska företag har leveranssäkerhetskrav på sina underleverantörer. Det är normalt att företag får problem att leverera varorna i tid till sina kunder ibland, vilket kan medföra stor ekonomisk förlust för företaget. Denna rapport är resultatet av ett examensarbete vid Mälardalens Högskola som utförts på uppdrag av International Aluminium Casting AB i Eskilstuna.Syftet med denna rapport är att se över IAC:s fabrik i Eskilstuna ute på Vilsta, för att kartlägga deras tillverkningsprocess och identifiera problemområden i tillverkningen som kan ha direkta effekter på leveranssäkerheten.För att uppnå syftet med arbetet utfördes först en litteraturstudie inom området effektiv produktion, följt av en empirisk studie som utfördes i fabriken på företaget. Detta ger arbetet en hög betryggande anknytning om hur verkligheten ser ut och ger innehållet en bekräftelse emot teorin inom området. En noggrann nulägesbeskrivning utfördes för att få en konkret bild över hur tillverkningsprocessen gick till och för att kunna se vart i processen det finns problem, vilket skulle kunna påverka företagets förmåga att leverera sina varor i tid till kunden.

"Att äta elefanten i småbitar" - Om den svenska regeringens feminism

After the last election Sweden has got a government that claims to be feminist. This thesis discusses whether the change of labels has also brought along policy formulated in a feminist way, arguing that the way policy is expressed affects how people see a certain problem. Three policy proposals are analysed, and in only one case the government seems to have been influenced by feminist ideas. The other proposals partly support claims made by new institutionalism that norms and routines in an organisation work to resist policy change, but also shows that feminist ideas are resisted more actively. The fact that so called policy entrepreneurs was present in the policy process at a certain period in time, probably counts for one explanation to the exceptional policy.

Samstämmighet mellan sjukgymnasters prioriteringar

Syftet med studien var att undersöka samstämmigheten mellan sjukgymnasters prioriteringar. Sjukgymnaster inom primärvård med landstings-, kommunalt- eller privat huvudmannaskap i Norrbottens Län tillfrågades om att prioritera 24 fiktiva patientfall. Samstämmigheten mellan prioriteringarna beräknades med Kendalls konkordanskoefficient (W). Samstämmigheten var låg, Kendalls W=0,224, med stor spridning i prioritering för varje patientfall. Studien hade stort bortfall som analyserades.

ETT DELAT LAND, ETT DELAT F?RTROENDE En teoripr?vande analys av allm?nhetens f?rtroende f?r h?gsta domstolen i ett polariserat USA

America finds itself divided in the midst of strict abortion laws and a contentious presidential election. This era of polarization, raises the question of whether such a great division has permeated through to the U.S Supreme Court. This paper uses two dominant theories of legitimacy; traditional and ideological, respectively, to analyze and compare this issue. The theories are compared empirically by investigating the level of public trust across opposing political affiliations. Unlike most previous research, the results suggest that variation in trust aligns with the ideological distance to the Court between democratic and republican voters. Trust is also found to be dependent on whether the electorate agrees with the decisions of the court or not.

Hur kopplar en grupp elever i skolår 5 skolmatematiken till vardagen?

Syftet med undersökningen var att granska vilka vardagliga situationer en grupp elever i skolår 5 associerade aritmetiska uppgifter till. I de aritmetiska uppgifterna var alla fyra räknesätten representerade då elever har olika förmågor att knyta an olika räknesätt. I studien undersöktes även om anknytningarna eleverna gjorde var rimliga i relation till verkligheten. Vi valde att använda en enkät där eleverna skrev räknehändelser till givna aritmetiska uppgifter med utgångspunkt i deras egen vardag. Undersökningen visade att mer än hälften av eleverna inte hade kunskapen att knyta an aritmetiska uppgifter till vardagliga egenupplevda situationer.

Måltidsmönster, kost - och - medievanor bland överviktiga 15-åriga flickor och pojkar

Objective: The aim of this study was to compare equations used to calculate BMR to values of BMR obtained from measurements in order to determine the most suitable equation to be used on children and adolescents with CF.Design: The participants where children and adolescents with CF. Data was collected from the division of Clinical Nutrition at Uppsala Akademiska Sjukhus. Age, weight, height, BMI, BMR, FFM and FM was recorded from 27 measurements. BMR from the participants collected from the indirect respiratory calorimetry was compared to the results obtained from five equations used to obtain a calculated value of BMR.Results: Tverskayas equation was best correlated with the measured BMR for the whole group. The equation underestimated BMR for the participants with a measured BMR over 1400 kcal/24h and overestimated BMR for participants with a measured BMR under 1400 kcal/24h.

Modelering av Wideband : Code Division Multiple Access

Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.
