Construction waste from the housing industry includes all unnecessary consumption of building materials. The definition of construction waste is construction materials that has not been built in and becomes waste. Constructions waste can be divided into two types of contributions: operational and work site contribution. Some of the common construction materials in housing industry have such low usage level as 75 % and the rest becomes construction waste. Low usage of construction materials creates unnecessary costs and has a major environmental impact.

The purpose of this paper is to compare the three search engines Web of Science, Google Scholar and MEDLINE in regards of recovery efficiency and the overlap of relevant documents when it comes to information searching for academic purposes. Furthermore, it raises the question whether freely available search engines and licensed search engines are interchangeable with each other. The empirical data in this study were collected through searches conducted in the three search engines Web of Science, Google Scholar and MEDLINE. Twenty search queries were used and the first twenty retrieved documents for each query were examined for relevance using previously designed criteria. The documents were scored by a binary relevancy scale and thereafter a precision value for each search engine was calculated.

Denna rapport har haft som uppgift att studera hur organisationer ska gå tillväga för att utvinna och värdera kunskap ifrån sitt befintliga informationssystem. Detta är en mycket viktig process då kunskap har blivit en av de absolut viktigaste resurserna för organisationer över hela världen. Utvinningen är viktig att effektivisera så att inte organisationer förlorar viktig kunskap när de avvecklar sitt gamla informationssystem för att bygga ett nytt och bättre system. Samtidigt är det viktigt att värdera ifall den utvunna kunskapen är relevant för organisationen. Ifall den inte är relevant så ska den inte sparas utan kasseras för att öka effektiviteten. För att undersöka detta problem så har en kvalitativ fallstudie genomförts hos ett medelstort företag som heter Colorex Sweden AB.

Erfarenheten av och forskning om sex- och samlevnadsundervisningen i skolan pekar på att undervisningen inte är till belåtenhet hos eleverna. För att utröna detta ytterligare valdes en studie med syftet att undersöka flickors och pojkars uppfattningar om innehåll och undervisningsmetoder inom sex- och samlevnadsundervisningen i skolåren 7-9. Hur undervisningen skall vara utformad för att kännas meningsfull för eleverna är av intresse i studien. Studien genomfördes utifrån en kvalitativ ansats med enkäter och gruppintervjuer som metod att skapa ett empiriskt material. Undersökningen genomfördes på två skolor.

In this study I investigated whether the strength in the manual response for emotional and neutral stimulus search arrays can explain some of the difference in reaction times (RT:s) for emotional stimuli, or not. Earlier, perceptual, cognitive and attentional processes has mostly been used to explain the variance in RT:s. Thirtythree individuals were asked to, as fast as possible, detect a target picture among distractor pictures in 3 rows x 4 columns arranged search arrays. The pictures were categorized in fear relevant animals (snake, spider) and neutral animals (cat). The results showed, more correct responses for cat target.

The purpose of this thesis is to investigate how Digital Signage systems such as public info kiosks can be designed to better fulfill its main use; to enlighten, encourage and influence the public with information. The challenges presented from earlier studies shows that the public interests and goals, together with proper and relevant content displayed in info kiosks have impact on the attention the public have towards public displays. Qualitative methods such as interviews, usability testing and observations were conducted to further examine how a public info kiosk can be designed to draw attention and grow interest amongst students at K3, Malmo University. Usability testing were used on the digital prototypes that were developed to ensure that the gestural user interface meet the requirements of a proper interaction from the users. Important insights were made concerning; the attention and interest to relevant content, the aspects of the gestural user interface along with the placement of the info kiosk in terms of context.

This is a study of innovative technologies that are primarily based on collaboration with a client who in this study is called FTG, because they chose to be anonymous. A problem set has been presented, analyzed and worked with. The result of this is that we found some weaknesses in the leadership that have influenced the motivation in the workgroup negatively. The study has focus on changing leadership in order to increase motivation and openness to innovation within the company. With this focus on change in leadership, we have done a basic search for relevant theories related to the topic and found interesting data to work with.

During test flights SAAB uses the data acquisition system COMET 16. The part of the system that receives the signals from the sensors and converts them is called KSM 15. The purpose of this thesis is to develop a data acquisition module on stacked PC/104 modules with a lower production cost. Our work has been divided into one part about analog signal conditioning and a second part with digital filtering and memory management of the sampled data. The analog part, designed of regular components like instrument amplifiers, voltage references, operational amplifiers and multiplexers, adjusts the sensors signal levels for the ADC?s that converts the signals.

Current research shows that the number of door openings during surgery is unjustifiably high. It is the operating room nurses task to ensure a hygienic and aseptic environment throughout the surgery with the goal of minimizing the risk of healthcare associated infection. The study aims to investigate whether the operating room nurse is attentive to the number of door openings during surgery and if the operating room nurse is attentive to the reasons behind the door openings. A pilot study with nine observations was carried out on two smaller hospitals in the region of Västra Götaland. The results showed a significant underestimation of the rated door openings compared with the actual ones.

Försvarsmaktens slutrapport från perspektivplaneringen 2007 innehåller ett avsnitt vilket avhandlar strategiskt samarbete med andra stater. Flera områden, vilka berör Försvarsmaktens operativa förmåga, identifieras som lämpliga för samarbete med de nordiska länderna. I detta sammanhang uttrycker Försvarsmakten ett bibehållande av nationell strategisk handlingsfrihet trots att uppbyggnaden av den operativa förmågan föreslås delas mellan olika länder. Uppsatsens problem och syfte tar sitt avstamp i ovan beskrivna sammanhang. Detta sker genom att undersöka vad begreppet handlingsfrihet kan sägas betyda när det uttrycks i sammanhang av mellanstatligt samarbete.

The purpose of this project was to find an understanding for why public agents working with introduction of immigrants have decided to co-operate and co-ordinate their efforts. Another purpose was to gain insights in what characterizes this co-operation.Seven interviews were made with practitioners working with these questions on national-, regional- and local levels. The material gathered in this process was then analysed using governance theory and more specific the parts dealing with Joined- up government and Whole- of Government. Two analytic tools were used in the analysis: wicked problems and network.The first of these, wicked problems, was made operational by the use of insecurities. Analysing the interviews along these lines proved very useful in explaining why public agents have decided to try to work together.

The purpose of this paper is to explore what objects that can be seized and how the management of a seizure should be conducted. Ability to take enforcement against an individual should be carefully weighed against the rights and freedoms that exist. Seizure is one of the various restraints that exist, and the regulation on which they appear is mainly in the Code of Judicial Procedure, Chapter 27th. To be able to apply coercive measures, it is fundamental prerequisite that a criminal investigation is initiated, but there exist some significant exceptions to this. There are also rules about who has the right to provide for the seizure, the decision can be taken by a prosecutor, an investigator, a police officer or, in special cases, the court.

The purpose of this study is to discuss the use of social media by the Swedish Police for democratic purposes. The idea of citizen empowerment is closely related to the development of new communication technologies such as social media. Yet many studies indicate that governmental institutions rarely make use of the assumed potentials of social media.In this study, the democratic potential of social media is derived from Habermas normative concept of deliberative participation. Operational definitions emphasize discursive equality, interactive reciprocity and external impact. The analytical framework is combined with qualitative text analysis to highlight the conditions of interaction between representatives of the Police and citizens.In conclusion: the democratic potential of social media, from a Habermasian point of view, is to a significant extent neglected at the expense of its strategic advantages.

Syftet med studien är att undersöka och synliggöra faktorer som kan påverka  dansmatteundervisnings relevans för elevers lärande i matematikämnet, detta i grundskolans tidigare år. Två kvalitativa insamlingsmetoder, i form av semistrukturerade intervjuer och observationer, har använts i undersökningen. Resultatet antyder att dansmatteundervisning kan vara relevant i och med att arbetssättet innebär en förståelseinriktad undervisning, där ett reflekterande arbetssätt med gemensamma samtal om matematiskt innehåll genomsyrar undervisningen. Att kommunikationen ökar, genom att både verbal och kinestetisk kommunikation samspelar i dansmatteundervisning, kan också bidra till att arbetssättet kan vara relevant. Pedagogens möjlighet till direkt återkoppling till elever anses som en styrka i dansmatteundervisning.

This report aims to study the condominium prices in central Stockholm and the factors thataffect these prices. A linear regression model was set up and data about relevant covariatessuch as floor area, mortgage rates and where the condominium is situated were gathered toassess if and how they influence the price. The raw data was processed and enhanced to gain asmuch relevant information as possible to the model. To determine the covariates? influence onthe final price, regressions were ran and various tests were performed on the output data.
