Validering av Alberta Context Tool (ACT) för bruk inom svensk kommunal äldrevård : Ett verktyg för implementering av evidensbaserad vård

The aim of this study was to conduct an instrument test of the Canadian questionnaire Alberta Context Tool (ACT) version Long-Term care for Swedish conditions. ACT is designed in order to measure the context in the care environment and different behaviours related to the changes in clinical practice. In total, 159 Licensed Practical Nurses (LPNs) and Registered Nurses (RNs) within municipality care of the elderly were included in the survey. The test included the instrument's reliability and face validity.The reliability test was implemented through calculation of Cronbach´s Alpha, and showed internal consistency for five of the scales of the ACT-instrument with Cronbach´s Alpha values ranging between 0,728 and 0,873. However, three dimensions got lower values (0,558 - 0,683).The analysis was carried out with content analysis and carried out for LPNs and RNs in separate groups. The majority of LPNs expressed that it was easy to respond to the questions (56%), while nine percent considered it as difficult. Eleven comments were given about questions that were perceived to be unclear, complicated or contained difficult words. In the RN group only 30 percent considered that the questions were easy to respond to. One third of the RNs considered that part of the questions were unclear, and six RNs expressed also which questions they experienced as unclear. In general, the questions in the ACT were perceived as relevant. The instrument's relevance as a tool to measure contextual factors that influence the implementation of evidence based nursing can also be considered to be determined. By modifying the content in the questionnaire in accordance with what appeared in this survey and to implement yet another test, the instrument should be considered to be relevant for use within Swedish municipality care of the elderly. ACT can be used both as a tool in the work on improvement of clinical practice and as a tool for further research about implementation of evidence based nursing.

Personalized Communications : A Cross Media tool for the future

Personalized communication is when the marketing message is adapted to each individual by using information from a databaseand utilizing it in the various, different media channels available today. That gives the marketer the possibility to create a campaign that cuts through today’s clutter of marketing messages and gets the recipients attention. PODi is a non-profit organization that was started with the aim of contributing knowledge in the field of digital printingtechnologies. They have created a database of case studies showing companies that have successfully implemented personalizedcommunication in their marketing campaigns. The purpose of the project was therefore to analyze PODi case studies with the main objective of finding out if/how successfully the PODi-cases have been and what made them so successful. To collect the data found in the PODi cases the authors did a content analysis with a sample size of 140 PODi cases from the year 2008 to 2010. The study was carried out by analyzing the cases' measurable ways of success: response rate, conversion rate, visited PURL (personalized URL:s) and ROI (Return On Investment). In order to find out if there were any relationships to be found between the measurable result and what type of industry, campaign objective and media vehicle that was used in the campaign, the authors put up different research uestions to explore that. After clustering and merging the collected data the results were found to be quite spread but shows that the averages of response rates, visited PURL and conversion rates were consistently very high. In the study the authors also collected and summarized what the companies themselves claim to be the reasons for success with their marketing campaigns. The resultshows that the creation of a personalized campaign is complex and dependent on many different variables. It is for instance ofgreat importance to have a well thought-out plan with the campaign and to have good data and insights about the customer in order to perform creative personalization. It is also important to make it easy for the recipient to reply, to use several media vehicles for multiple touch points and to have an attractive and clever design.

Är organisationen mogen för evidensbaserad vård? : översättning och validering av Alberta Context Tool och beskrivning av sjuksköterskors skattning av kontextuella faktorer inom ortopedisk vård

Syftet med denna studie var att reliabilitetstesta Alberta Context Tool (ACT) i svensk hälso- och sjukvård och beskriva ortopedsjuksköterskors skattning av kontextuella faktorer såsom ledarskap, arbetskultur, återkoppling, utvecklingsmöjligheter och forskningsanvändning, som kan påverka möjligheten att omsätta forskningsresultat i vårdarbetet. Urvalet bestod av 119 sjuksköterskor som arbetade på ortopediska vårdavdelningar på sex olika sjukhus i mellersta Sverige. ACT är ett frågeformulär framtaget utifrån de senaste årens forskning om vilka faktorer i kontexten som har betydelse för sjuksköterskors forskningsanvändning. Reliabilitetstest gjordes enligt analys med Chronbach`s Alpa och innehållsvaliditet. Resultatet visade att ACT var relevant att användas för sjuksköterskor som arbetar på ortopedisk vårdavdelning i Sverige. Reliabilitetstesten med Chronbach´s Alpa gav värden nära 0,7 för de åtta frågeområden som behandlar kontexten.Sjuksköterskorna rapporterade att det fanns brister i många av de delar av kontexten som enligt forskning visat sig ha betydelse för möjligheten att implementera evidensbaserad vård. Sjuksköterskorna trivdes med sitt arbete och kände att deras kunskaper värderades högt i vårdteamet. Resultatet visade dock att det inte fanns tillräckligt stöd från ledningen för att utveckla vården. De rapporterade att de nästan inte alls fick återkoppling i vårdarbetet. Det saknades stödfunktioner och strategier för att implementering av forskningsresultat skulle vara möjligt att implementera i vårdarbetet. Majoriteten av sjuksköterskorna såg positivt på forskningsanvändning.

Evaluation of galling resistance for some selected combinations of tool steels/stainless steel sheet materials/lubricants using pin-on-disc testing

Stainless steels are well known to be prone to cold welding and material transfer in sliding contacts and therefore difficult to cold form unless certain precautions as discussed in this paper are taken. In the present study different combinations of tool steels/stainless steels/lubricants has been evaluated with respect to their galling resistance using pin-on-disc testing. The results show that a high galling resistance is favored by a high stainless steel sheet hardness and a blasted stainless steel sheet surface topography. The effect of type of lubricant was found to be more complex. For example, the chlorinated lubricants failed to prevent metal-to-metal contact on a brushed sheet surface but succeeded on a blasted sheet surface of the same stainless steel material. This is believed to be due to a protective tribofilm which is able to form on the blasted surface, but not on the brushed surface.

Extended local labor markets due to high speed trains : Visualization of estimations in the Swedish national travel demand forecasting tool, SAMPERS

Wider economic benefits resulting from extended geographical mobility is one argument for investments in high-speed rail. More specifically, the argument for high-speed trains in Sweden has been that they can help to further spatially extend labor market regions which in turn has a positive effect on growth and development. In this paper the aim is to cartographically visualize the potential size of the labor markets in areas that could be affected by possible future high-speed trains. The visualization is based on the forecasts of labor mobility with public transport made by the Swedish national mobility transport forecasting tool, SAMPERS, for two alternative high-speed rail scenarios. The analysis, not surprisingly, suggests that the largest impact of high-speed trains results in the area where the future high speed rail tracks are planned to be built. This expected effect on local labor market regions of high-speed trains could mean that possible regional economic development effects also are to be expected in this area. However, the results, in general, from the SAMPERS forecasts indicaterelatively small increases in local labor market potentials.

ICT as a tool in English teaching : A literature review on the use of ICT for Swedish students with learning difficulties and their literacy learning in grades 7-9

Information and communication technology (ICT) is a subject that is being discussed as a tool that is used within education around the world. Furthermore it can be seen as a tool for teachers to individualize students´ education. Students with literacy difficulties, such as dyslexia, are in constant need of new ways to learn, and new ways to be motivated to learn. The aim of this study is to see what research says in regard to how ICT can be used as a tool to help students with literacy difficulties. Literacy difficulties can be due to a number of things, such as the student has not been taught how to read, trouble within the family which can cause distress, or a neurological disorder such as dyslexia. Furthermore, the main research questions will focus on how ICT can be compared to traditional education forms, such as books and a more teacher centered education within the classroom, and whether ICT can be preferred. The results of this literature review indicates that ICT can be seen as a way for teachers to help students with literacy difficulties gain more self-esteem – something the literature tells us students with learning difficulties lack. The results also show how ICT can lead to a more individualized education. This is due to tools that increase reading comprehension and tools that give direct response when working with ICT, which helps students work more independently.

Wear of coated and uncoated PCBN cutting tool used in turning and milling

This licentiate thesis has the main focus on evaluation of the wear of coated and uncoated polycrystalline cubic boron nitride cutting tool used in cutting operations against hardened steel. And to exam the surface finish and integrity of the work material used. Harder work material, higher cutting speed and cost reductions result in the development of harder and more wear resistance cutting tools. Although PCBN cutting tools have been used in over 30 years, little work have been done on PVD coated PCBN cutting tools. Therefore hard turning and hard milling experiments with PVD coated and uncoated cutting tools have been performed and evaluated. The coatings used in the present study are TiSiN and TiAlN. The wear scar and surface integrity have been examined with help of several different characterization techniques, for example scanning electron microscopy and Auger electron spectroscopy.   The results showed that the PCBN cutting tools used displayed crater wear, flank wear and edge micro chipping. While the influence of the coating on the crater and flank wear was very small and the coating showed a high tendency to spalling. Scratch testing of coated PCBN showed that, the TiAlN coating resulted in major adhesive fractures. This displays the importance of understanding the effect of different types of lapping/grinding processes in the pre-treatment of hard and super hard substrate materials and the amount and type of damage that they can create. For the cutting tools used in turning, patches of a adhered layer, mainly consisting of FexOy were shown at both the crater and flank. And for the cutting tools used in milling a tribofilm consisting of SixOy covered the crater. A combination of tribochemical reactions, adhesive wear and mild abrasive wear is believed to control the flank and crater wear of the PCBN cutting tools. On a microscopic scale the difference phases of the PCBN cutting tool used in turning showed different wear characteristics. The machined surface of the work material showed a smooth surface with a Ra-value in the range of 100-200 nm for the turned surface and 100-150 nm for the milled surface. With increasing crater and flank wear in combination with edge chipping the machined surface becomes rougher and showed a higher Ra-value. For the cutting tools used in milling the tendency to micro edge chipping was significant higher when milling the tools steels showing a higher hard phase content and a lower heat conductivity resulting in higher mechanical and thermal stresses at the cutting edge.
