Pupils' Interaction with the Exhibits According to the Learning Behaviour Model

Science centres are one of the best opportunities for informal study of natural science. There are many advantages to learn in the science centres compared with the traditional methods: it is possible to motivate and supply visitors with the social experience, to improve people’s understandings and attitudes, thereby bringing on and attaching wider interest towards natural science. In the science centres, pupils show interest, enthusiasm, motivation, self-confidence, sensitiveness and also they are more open and eager to learn. Traditional school-classes however mostly do not favour these capabilities. This research presents the qualitative study in the science centre. Data was gathered from observations and interviews at Science North science centre in Canada. Pupils’ learning behaviours were studied at different exhibits in the science centre. Learning behaviours are classified as follows: labels reading, experimenting with the exhibits, observing others or exhibit, using guide, repeating the activity, positive emotional response, acknowledged relevance, seeking and sharing information. In this research, it became clear that in general pupils do not read labels; in most cases pupils do not use the guides help; pupils prefer exhibits that enable high level of interactivity; pupils display more learning behaviours at exhibits that enable a high level of interactivity.

Corporate identity through graphic design

The degree project has been implemented abroad in Brisbane, Australia. A literature study has beenperformed parallel to the practical work within the subject »Corporate identity through graphicaldesign«. In this study deeper research has been made concerning the establishment and manifestationof a corporate identity and its program. The knowledge given from this study has been put into practicethrough two larger projects.The first project was carried out at De Pasquale, advertising agency in Brisbane, where a corporateidentity program was designed for a new company. The company is a fitness centre, called KnockoutFitness, which specializes in different types of boxing training sessions such as Boxing, Thai Bow andBoxercise but also Aqua aerobics. They needed a full corporate identity program including a logotype,business card, letter paper-paper and address labels.The second project was carried out at Queensland University of Technology in Brisbane. A promotioncampaign was designed for the Department of Visual Arts, which included two information folders andone advertisement. The purpose of the campaign was to promote both the undergraduate and postgraduatecourses offered within the department.

Narration, Visualization and Mind : Movies in everyday life as a resource for utopian self-reflection

The paper is analyzing how people in late modern society characterized by de-traditionalization, use moving images as a cultural resource for the construction of meaningful subjective world views. As a theoretical concept with several dimensions, “sacralization of the self” (Woodhead & Heelas 2000: 344), is related to media theory. With a critical focus on ‘the self’, as a core aspect in contemporary media society Eric W. Rothenbuhler labels the individual self as one of “the sacred objects of modern culture” (Rothenbuhler 2006: 31).I want to emphasize the need for case studies in order to undertake a critical investigation about ‘the self’ and how consumption of fiction film is interconnected to spectator´s creation of self images, but also to understand how film engagement elicits self-reflection (Giddens 1991, Axelson 2008, Vaage 2009a). The paper make use of empirical data to illustrate and theoretically develop perspectives on how the audience uses fiction film in every-day life for the construction of the self, as well for the construction of more profound and long-lasting ideas of being part of a moral community (Brereton 2005, Jerslev 2006, Klinger 2008, Mikkola et al. 2007, Vaage 2009b). Some empirical findings support a conclusion that moving images creates a transitional space for the human mind, with the capacity of transporting the spectator from real life to fiction and back to real life again, helping the individual with an ongoing process of transforming the self, dealing with who you actually are, and who you want to become (Axelson 2008, Vaage 2009b).

Annual CO-emissions of combined pellet and solar heating systems

Emissions are an important aspect of a pellet heating system. High carbon monoxide emissions are often caused by unnecessary cycling of the burner when the burner is operated below the lowest combustion power. Combining pellet heating systems with a solar heating system can significantly reduce cycling of the pellet heater and avoid the inefficient summer operation of the pellet heater. The aim of this paper was to study CO-emissions of the different types of systems and to compare the yearly CO-emissions obtained from simulations with the yearly CO-emissions calculated based on the values that are obtained by the standard test methods. The results showed that the yearly CO-emissions obtained from the simulations are significant higher than the yearly CO-emissions calculated based on the standard test methods. It is also shown that for the studied systems the average emissions under these realistic annual conditions were greater than the limit values of two Eco-labels. Furthermore it could be seen that is possible to almost halve the CO-emission if the pellet heater is combined with a solar heating system.

Etikettdesign och prisklass för röda viner

Denna studie syftar till att undersöka om det finns ett samband mellan designfaktorer och prisklass på rödvinsetiketter. För att kartlägga förekommande designfaktorer har en visuell innehållsanalys gjorts inom tre olika prisklasser hämtad från Systembolagets hemsida. Utifrån den visuella innehållsanalysens resultat designades tre vinetiketter för varje prisklass. För att ta reda på om dessa designfaktorer hade ett samband med den tänkta prisklassen testades vinetiketterna mot konsumenter genom en webbenkät. Slutsatsen var att det fanns vissa generella drag som skiljer prisklasserna åt även om många designfaktorer var vanligt förekommande för alla prisklasser. Utifrån respondenternas svar visade sig vissa av designfaktorerna vara mer eller mindre tydliga för den tilltänkta prisklassen.

Emissions from realistic operation of residential wood pellets heating systems

Emissions from residential combustion appliances vary significantly depending on the firing behaviours and combustion conditions, in addition to combustion technologies and fuel quality. Although wood pellet combustion in residential heating boilers is efficient, the combustion conditions during start-up and stop phases are not optimal and produce significantly high emissions such as carbon monoxide and hydrocarbon from incomplete combustion. The emissions from the start-up and stop phases of the pellet boilers are not fully taken into account in test methods for ecolabels which primarily focus on emissions during operation on full load and part load. The objective of the thesis is to investigate the emission characteristics during realistic operation of residential wood pellet boilers in order to identify when the major part of the annual emissions occur. Emissions from four residential wood pellet boilers were measured and characterized for three operating phases (start-up, steady and stop). Emissions from realistic operation of combined solar and wood pellet heating systems was continuously measured to investigate the influence of start-up and stop phases on total annual emissions. Measured emission data from the pellet devices were used to build an emission model to predict the annual emission factors from the dynamic operation of the heating system using the simulation software TRNSYS. Start-up emissions are found to vary with ignition type, supply of air and fuel, and time to complete the phase. Stop emissions are influenced by fan operation characteristics and the cleaning routine. Start-up and stop phases under realistic operation conditions contribute 80 – 95% of annual carbon monoxide (CO) emission, 60 – 90% total hydrocarbon (TOC), 10 – 20% of nitrogen oxides (NO), and 30 – 40% particles emissions. Annual emission factors from realistic operation of tested residential heating system with a top fed wood pelt boiler can be between 190 and 400 mg/MJ for the CO emissions, between 60 and 95 mg/MJ for the NO, between 6 and 25 mg/MJ for the TOC, between 30 and 116 mg/MJ for the particulate matter and between 2x10-13 /MJ and 4x10-13 /MJ for the number of particles. If the boiler has the cleaning sequence with compressed air such as in boiler B2, annual CO emission factor can be up to 550 mg/MJ. Average CO, TOC and particles emissions under realistic annual condition were greater than the limits values of two eco labels. These results highlight the importance of start-up and stop phases in annual emission factors (especially CO and TOC). Since a large or dominating part of the annual emissions in real operation arise from the start-up and stop sequences, test methods required by the ecolabels should take these emissions into account. In this way it will encourage the boiler manufacturers to minimize annual emissions. The annual emissions of residential pellet heating system can be reduced by optimizing the number of start-ups of the pellet boiler. It is possible to reduce up to 85% of the number of start-ups by optimizing the system design and its controller such as switching of the boiler pump after it stops, using two temperature sensors for boiler ON/OFF control, optimizing of the positions of the connections to the storage tank, increasing the mixing valve temperature in the boiler circuit and decreasing the pump flow rate. For 85 % reduction of start-ups, 75 % of CO and TOC emission factors were reduced while 13% increase in NO and 15 % increase in particle emissions was observed.

Etikettdesign hos framgångsrika alesorter i Sverige från olika produktionsländer

Föreliggande studie syftar till att kartlägga vilka designfaktorer som främst förekommer på etiketter hos framgångsrika aleproducenter från olika länder, samt undersöka om konsumenter kan urskilja produktionsland endast genom granskning av etiketten. För att undersöka detta genomfördes en visuell innehållsanalys för att ta fram designfaktorer för fem utvalda länder, varefter fem typexempel skapades. Typexemplen testades på konsumenter via en webbenkät. Slutsatsen är att det i vissa fall går att ta fram ett typexempel och i vissa fall kan en del av konsumenterna se vilket det tänkta produktionslandet är. I majoriteten av fallen gick det emellertid inte att ta fram ett perfekt typexempel och konsumenten kunde inte urskilja det tänkta produktionslandet.

English product names and descriptions in two Swedish supermarkets : A quantitative and qualitative analysis

This study aimed to investigate what proportion of two household staples, soap and crispbread products, in two Swedish supermarkets had English product names or descriptions, and attempted a qualitative analysis of the English language used. Out of the Swedish brands, 54-62% of the soap products had names and/or product descriptions containing English, compared to 13-15% of the crispbread; these differences were in line with previous research, suggesting English is used more to market certain product groups than other ones. Earlier studies have also proposed that English could be considered an ‘elite’ language in Sweden, and it might thus be more commonly found on more exclusive/expensive products, or in the supermarket primarily aiming at higher-income customers. However, the differences between the two supermarkets, and between the more and less expensive products, were not great enough for any firm conclusions. When products had a mixture of languages on the label, English was most often used for product names or part of names, not so often for product descriptions. Further studies with a larger amount of data would be required for more reliable conclusions, especially for the qualitative analyses. It would also be interesting to investigate customers’ attitudes towards the use of English on product labels.
