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.

The Generation Gap: What Generation Gap? : Management, Technology, Training, and Evolving Skills

Contrary to divisive labels to describe generations, members of different age groups have much to teach each other: Younger workers bring fresh perspectives to old issues, while older workers' valuable organizational history help inform current contexts. All age groups in the workplace benefit in learning from each other's perspectives.

A gestão da estratégia mercadologica sob uma nova perspectiva: existe relação entre a física e a administração?

A Física e a Administração concentram suas pesquisas sobre fenômenos que, de certa forma, se assemelham, fazendo com que nos questionemos a respeito da grande integral do universo a que estamos submetidos. Em uma exploração por analogias, aproxima-se aqui o mundo organizacional ao dos sistemas UnIVerSaIS, instáveis e não-integráveis, onde a flecha do tempo é quem determina a evolução dos mesmos. Mostra-se que na Administração, como na Física, tudo parece convergir na direção de um inesgotável repertório de bifurcações e possibilidades para o destino mercadológico de produtos, serviços e marcas ao longo de um continuum. Para amenizar os efeitos dessas incertezas, é buscada uma simplificação desses complexos sistemas sociais através de uma proposta de modelo baseado em fatores consagrados pela literatura da gestão empresarial como norteadores das escolhas dos consumidores; um processo gaussiano da 'percepção do valor', que pode servir de ferramenta nas decisões estratégicas e gerenciais dentro das empresas.

O futuro da indústria da música no Brasil

A indústria da música tem enfrentado grandes mudanças e transformações nos últimos anos. O setor sempre se caracterizou por ser muito dinâmico, especialmente com o constante advento de novas tecnologias. Contudo, a tendência atual tem se demonstrado substancialmente diferente das passadas. As primeiras tecnologias como as fitas cassetes e discos de vinil começaram a perder espaço para o CD quando este foi introduzido no mercado no início dos anos 80 (PIKAS, PIKAS, & LYMBURNER, 2011). Contudo, o modelo de negócio da indústria permaneceu o mesmo, as grandes gravadoras continuavam a ser os grandes players do setor, e não enfrentavam competições externas. Este cenário mudou no final do século XX. Os arquivos de MP3, que foram desenvolvidos em 1989, mas que não alcançaram grande escala no mercado Americano até 1999, começaram a ganhar popularidade (PIKAS, PIKAS, & LYMBURNER, 2011). Aliada a esta popularidade, surgem também os downloads ilegais de arquivos e grandes perdas financeiras para as grandes gravadoras. Dado este cenário dinâmico e indefinido, este trabalho propõe focar-se no futuro da indústria da música e não nas tendências atuais ou passadas. O objetivo é prospectar e analisar possíveis cenários futuros para os próximos anos no Brasil. Em outras palavras, mostrar diferentes possibilidades e características que o setor possa apresentar em alguns anos. Para isso, este trabalho usará a metodologia de cenários prospectivos, além de entrevistas com experts da indústria que possibilitarão o desenvolvimento e a descoberta destes possíveis cenários.

Preferential location of lidocaine and etidocaine in lecithin bilayers as determined by EPR, fluorescence and H-2 NMR

We have examined the effect of the uncharged species of lidocaine (LDC) and etidocaine (EDC) on the acyl chain moiety of egg phosphatidylcholine liposomes. Changes in membrane organization caused by both anesthetics were detected through the use of EPR spin labels (5, 7 and 12 doxyl stearic acid methyl ester) or fluorescence probes (4, 6, 10, 16 pyrene-fatty acids). The disturbance caused by the LA was greater when the probes were inserted in more external positions of the acyl chain and decreased towards the hydrophobic core of the membrane. The results indicate a preferential insertion of LDC at the polar interface of the bilayer and in the first half of the acyl chain, for EDC. Additionally, 2 H NMR spectra of multilamellar liposomes composed by acyl chain-perdeutero DMPC and EPC (1:4 mol%) allowed the determination of the segmental order (S-mol) and dynamics (T-1) of the acyl chain region. In accordance to the fluorescence and EPR results, changes in molecular orientation and dynamics are more prominent if the LA preferential location is more superficial, as for LDC while EDC seems to organize the acyl chain region between carbons 2-8, which is indicative of its positioning. We propose that the preferential location of LDC and EDC inside the bilayers creates a "transient site", which is related to the anesthetic potency since it could modulate the access of these molecules to their binding site(s) in the voltage-gated sodium channel.

Legislação de rotulagem nutricional: instrumento de informação na promoção de escolhas alimentares - Natal-RN

Resolutions of the Board of numbers 359 and 360, of December 23, 2003, relating to Nutrition Labelling for Packaged Foods, establish quality standards and provide the education activities for health consumption, since one of the factors that enable the selection of healthier foods are the food labels as an important part in nutrition education. This is a descriptive study with a cross-sectional design. To calculate sample size, it was considered a margin of error of 20%, confidence level of 95% and prevalence of 52.5% for verifying nutritional information in a pilot study conducted in 2007. A total of 145 subjects were interviewed, resulting in 371 consumers in Natal, Rio Grande do Norte, Brazil, in order to determine prevalence of consulting nutritional information contained on food labels as a nutritional guideline for consumers and its association with sociodemographic variables as well as identify the intervention measures suggested by intervieweds so that this information can be better used to select healthy foods. Twenty-five of the 69 supermarkets belonging to the Supermarket Association of Rio Grande do Norte (ASSURN) were randomly selected. Data collection relied on interviews and extensive direct observation, using a semi-structured form composed of eight closed questions, some of which were multiple choice, and ten open questions. The chi-square test was performed for statistical analysis, using Statistical Package for Social Sciences (SPSS) 15.0 software. Label information most consulted was: expiry date (91.6%); product brand (49.4%); nutritional information (47.0%); zero trans fat (32.9%); zero sugar content (12.8%); zero fat content (3.0%); rich in fibers (2.7%); whether light or diet (30.4%); list of ingredients (16.8%); whether the product contained gluten or not (4.1%). When asked about the importance of nutritional information, 96.8% of the subjects responded important or very important ; of these 46.6% and 3.8% reported partially or totally understanding the information presented. It was found that 41.6% of the consumers consulted nutritional information for dietary reasons related to nontransmissible chronic diseases and 35.7% to be able to choose healthier foods. The data show a significant association between motivation to choose healthier foods and higher family income and schooling (p<0.0001). The intervention measures mentioned to make nutritional information better understood and used were: information and orientation about nutritional information, provided by qualified professionals in the supermarkets, the commercial establishment or the product manufacturer (73.9%) and media disclosure about the nature, importance and purpose of nutritional information (42.9%). In despite of communication noises the consumers use the nutrition claim for the nutritional guidance, showing association with some demographic variables. However, they desire the implementation of intervention measures that can be contextualized in the political construction of nutrition education to promote healthy food choices

Openability of soft drinks PET packagings

Studies on packaging accessibility are still incipient in Brazil. Many of these packagings can represent a challenge to users, whether due to non-informative labels, tricky tabs or seals, or even those that need strength to open. This paper brings a simple test to determine the necessary torque force to open PET bottles, and to predict the amount of users that could not open it. The findings suggest that a considerable amount of users could not open it or would have some difficulties to exert the necessary force.

Aspectos linguístico-ergonômicos em rótulos: avaliação da linguagem verbo-visual de rótulos de embalagens para alimentos achocolatados

We have been living in a world of packed products. The package and the labels support the companies to communicate with the customers in addition to give protection, storage and convenience in proportion to the products that move in the price list. The labels mainly add up a value which helps the companies differ their products and increase the value of the brands among the final customers. However, the information given in the label are not clear sometimes. It displays a verbal-visual defective language resulted from a poor visibility, legibleness and comprehensibleness of the verbal and visual marks. The aim of this research is to verify, according to the costumers‟ view, the level of the clarity in the informative texts, harmony and ergonomic conformity of the package labels in the chocolate powder of the Claralate brand, considering the linguistic aspects presented on the labels. The criteria to evaluate the chocolate package selected were based on the linguistic field: the organization and the structure of the text derided from the classification of the textual genre; the clarity and the comprehension of the language utilized on those labels. From the ergonomic view, the informative and ergonomic conformity, based on the following requirements: legibility, symbols, characters, reading fields and intermission of the written lines. Therefore, the research done july 2007 and added july 2011 had a structured questionnaire in the interview put to the 118 customers of the chocolate package that go shopping in one of the two supermarkets in Floriano, Piauí São Jorge and/or Super Quaresma. The main results of the investigation show that the linguistic aspects in the informative texts of the labels provide the customers‟ expectancy partially, while the consideration of the informative ergonomic analyzed can contribute to the improvement of the information and consequent visual progress of those, on the labels of chocolate package investigated. As recommendation towards the maker of the product, the outcome of the research indicates: harmonize the proportion of the letters and numbers; enlarge the letters size; make the visual information more comprehensive determined by the reading field; put the expiry date in a better visual place
