Front End Evaluation of 'Tester' Exhibition to be Developed into a Travelling Sports Exhibition

The purpose of this evaluation is to develop a framework that will help in planning and implementing the mobile sport exhibition, increase visitor satisfaction and aid At Bristol in building successful exhibits. The evaluation mainly focuses on visitor interaction with exhibits. It is believed that learning does occur in science centres and museums. The evaluation will therefore find out if learning occurs in the Sports exhibition and if so, the nature of the learning outcomes. The evaluation also discusses advantages and disadvantages of travelling exhibitions and identifies the characteristics of good exhibits that form the basis of the framework.From the results, an indication is that children make the larger proportion of visitors to Sportastic. Their age ranges, under 10 and 10 to 15 years constituted 21% and 30% respectively. The three most enjoyed exhibits are the Sprint Challenge (running), BATAK (test your reaction and Hot Shots (football). Visitors say these exhibits are enjoyed because they are fun, competitive, entertaining, interactive and hands-on. Skateboard Challenge and Skeleton Bob are among the exhibits least enjoyed since they are reported to be boring and uncomfortable to use. The learning outcomes from the exhibits are; increased knowledge about balancing, reaction, pulse and strength.

Pupils' interaction with a Science Centre: Communication perspective analysis

The purpose of this study was to investigate pupils’ knowledge about science and what role science center is playing as a medium of communication to increase knowledge among students. This study also tried to find out pupils’ interaction: how they use science center as a source of scientific information, what they learn from their visit to a science center, their pattern of communication with it. This project also measured attraction, holding and learning power of exhibits of the science center at Dalarna University in Borlänge and learning power of planetarium program and slide show of Stella Nova Planetarium at Dalarna University.The subjects of this study consisted of students of class seven and eight and teachers of an urban school in Borlänge, Sweden. To find out students’ learning in a science center a pre and post visit test were conducted through questionnaires. Interview method by questionnaires was also used to explore pupils’ interaction with science center.The results of this study show that students learn by their visit to a science center but learning was not statistically significant (0.05).Girls learnt better than boys. School classes that have better pre-knowledge about science before a visit to a science center learnt worse than other classes having less pre-knowledge. Girls and boys interact with a science center in different ways. Science center is playing important role as a science communicator.

An Evaluation of”Middle Ages Dead or Live?”The first interactive exhibition at the National Museum of History

This is a study conducted at, and for, the National Museum of History in Stockholm. The aim of the study was to confirm or disconfirm the hypothesis that visitors in a traditional museum environment might not take part in interactivity in an interactive exhibition. And if they do the visitors might skip the texts and objects on display. To answer this and other questions a multiple method was used. Both non participant observations and exit interviews were conducted. After a description of the interactive exhibits, theory of knowledge and learning is presented before the gathered data is presented. All together 443 visitors were observed. In the observations the visitors were timed on how much time they spent in the room, the time spent on the interactivity, texts and objects. In the 40 interviews information about visitors’ participation in the interactivity was gathered. What interactivity the visitor found easiest, hardest, funniest and most boring.The result did not confirm the hypothesis. All kinds of visitors, children and adults, participated in the interactivities. The visitors took part in the texts and objects and the interactive exhibits.

Théâtre du Grand-Guignol : Les mécanismes de la peur dans deux pièces du théâtre médical d’André de Lorde et Alfred BinetL’Obsession et Une leçon à la Salpêtrière .

Le Grand-Guignol n’a reçu que peu d’attention critique sérieuse jusqu’à la fin des années 1980. Ce petit théâtre a pendant 65 ans, de 1897 à 1962, offert des pièces d’un genre nouveau mêlant terreur, violence et souvent érotisme. Le succès était au rendez-vous et le Théâtre du Grand-Guignol est longtemps resté une attraction incontournable de Paris. Les pièces choisies pour ce mémoire sont issues de ce répertoire et ont cela de particulier qu’elles ont été écrites en collaboration entre un écrivain, André de Lorde, et un psychologue, Alfred Binet. Malgré leurs différences, ces pièces ont une constante, un point commun : elles suscitent toutes la peur chez le spectateur. C’est précisément la façon dont Binet et de Lorde établissent cette peur à travers leurs pièces qui sera l’objet d’étude de ce mémoire. Ce mémoire se limite à l’analyse de deux œuvres en particulier : L’Obsession, et Une leçon à la Salpêtrière. Appréhender la notion de peur dans une œuvre théâtrale impose de réfléchir non seulement aux thèmes développés mais également à la construction dramatique du récit et à sa mise en scène. Dans le cas spécifique d’une pièce Grand-Guignol, il y aura une dimension supplémentaire à inclure : ce que l’on peut appeler « l’expérience Grand-Guignol ». De quelles façons le fait même d’aller voir une pièce dans ce théâtre participait-il à l’anticipation et au sentiment de peur nécessaire à l’efficacité des pièces ?  Après un bref rappel de l’histoire du Grand-Guignol, les causes externes comme le quartier de Montmartre, mais aussi les habiles coups publicitaires des premiers directeurs artistiques ainsi que la configuration du théâtre lui-même sont étudiées pour montrer comment elles ont largement contribué à créer un véritable mythe autour du Grand-Guignol. Dans la deuxième partie, une analyse spécifique des deux pièces mentionnées précédemment est faite. Les questions suivantes ont été posées : sur quels thèmes pouvaient bien jouer les auteurs pour toucher leur public ? En quoi ces thèmes reflétaient-ils les peurs de l’époque, c’est-à-dire de la « Belle Epoque » ? Dans la dernière partie, une analyse textuelle et scénique a été faite au cours de laquelle il a été tenté de comprendre comment les auteurs provoquent et entretiennent la peur et l’angoisse à travers à la fois la construction dramatique des pièces et leurs jeux de scène.

An Experimental Study of Submerged Entry Nozzles (SEN) Focusing on Decarburization and Clogging

The submerged entry nozzle (SEN) is used to transport the molten steel from a tundish to a mould. The main purpose of its usage is to prevent oxygen and nitrogen pick-up by molten steel from the gas. Furthermore, to achieve the desired flow conditions in the mould. Therefore, the SEN can be considered as a vital factor for a stable casting process and the steel quality. In addition, the steelmaking processes occur at high temperatures around 1873 K, so the interaction between the refractory materials of the SEN and molten steel is unavoidable. Therefore, the knowledge of the SEN behaviors during preheating and casting processes is necessary for the design of the steelmaking processes  The internal surfaces of modern SENs are coated with a glass/silicon powder layer to prevent the SEN graphite oxidation during preheating. The effects of the interaction between the coating layer and the SEN base refractory materials on clogging were studied. A large number of accretion samples formed inside alumina-graphite clogged SENs were examined using FEG-SEM-EDS and Feature analysis. The internal coated SENs were used for continuous casting of stainless steel grades alloyed with Rare Earth Metals (REM). The post-mortem study results clearly revealed the formation of a multi-layer accretion. A harmful effect of the SENs decarburization on the accretion thickness was also indicated. In addition, the results indicated a penetration of the formed alkaline-rich glaze into the alumina-graphite base refractory. More specifically, the alkaline-rich glaze reacts with graphite to form a carbon monoxide gas. Thereafter, dissociation of CO at the interface between SEN and molten metal takes place. This leads to reoxidation of dissolved alloying elements such as REM (Rare Earth Metal). This reoxidation forms the “In Situ” REM oxides at the interface between the SEN and the REM alloyed molten steel. Also, the interaction of the penetrated glaze with alumina in the SEN base refractory materials leads to the formation of a high-viscous alumina-rich glaze during the SEN preheating process. This, in turn, creates a very uneven surface at the SEN internal surface. Furthermore, these uneven areas react with dissolved REM in molten steel to form REM aluminates, REM silicates and REM alumina-silicates. The formation of the large “in-situ” REM oxides and the reaction of the REM alloying elements with the previously mentioned SEN´s uneven areas may provide a large REM-rich surface in contact with the primary inclusions in molten steel. This may facilitate the attraction and agglomeration of the primary REM oxide inclusions on the SEN internal surface and thereafter the clogging. The study revealed the disadvantages of the glass/silicon powder coating applications and the SEN decarburization. The decarburization behaviors of Al2O3-C, ZrO2-C and MgO-C refractory materials from a commercial Submerged Entry Nozzle (SEN), were also investigated for different gas atmospheres consisting of CO2, O2 and Ar. The gas ratio values were kept the same as it is in a propane combustion flue gas at different Air-Fuel-Ratio (AFR) values for both Air-Fuel and Oxygen-Fuel combustion systems. Laboratory experiments were carried out under nonisothermal conditions followed by isothermal heating. The decarburization ratio (α) values of all three refractory types were determined by measuring the real time weight losses of the samples. The results showed the higher decarburization ratio (α) values increasing for MgO-C refractory when changing the Air-Fuel combustion to Oxygen-Fuel combustion at the same AFR value. It substantiates the SEN preheating advantage at higher temperatures for shorter holding times compared to heating at lower temperatures during longer holding times for Al2O3-C samples. Diffusion models were proposed for estimation of the decarburization rate of an Al2O3-C refractory in the SEN. Two different methods were studied to prevent the SEN decarburization during preheating: The effect of an ZrSi2 antioxidant and the coexistence of an antioxidant additive and a (4B2O3 ·BaO) glass powder on carbon oxidation for non-isothermal and isothermal heating conditions in a controlled atmosphere. The coexistence of 8 wt% ZrSi2 and 15 wt% (4B2O3 ·BaO) glass powder of the total alumina-graphite refractory base materials, presented the most effective resistance to carbon oxidation. The 121% volume expansion due to the Zircon formation during heating and filling up the open pores by a (4B2O3 ·BaO) glaze during the green body sintering led to an excellent carbon oxidation resistance. The effects of the plasma spray-PVD coating of the Yttria Stabilized Zirconia (YSZ) powder on the carbon oxidation of the Al2O3-C coated samples were investigated. Trials were performed at non-isothermal heating conditions in a controlled atmosphere. Also, the applied temperature profile for the laboratory trials were defined based on the industrial preheating trials. The controlled atmospheres consisted of CO2, O2 and Ar. The thicknesses of the decarburized layers were measured and examined using light optic microscopy, FEG-SEM and EDS. A 250-290 μm YSZ coating is suggested to be an appropriate coating, as it provides both an even surface as well as prevention of the decarburization even during heating in air. In addition, the interactions between the YSZ coated alumina-graphite refractory base materials in contact with a cerium alloyed molten stainless steel were surveyed. The YSZ coating provided a total prevention of the alumina reduction by cerium. Therefore, the prevention of the first clogging product formed on the surface of the SEN refractory base materials. Therefore, the YSZ plasma-PVD coating can be recommended for coating of the hot surface of the commercial SENs.

"Bolagsverket är mer modernt än jag tänkte mig" : Hur kan statliga myndigheter arbeta med Employer Branding för att attrahera Generation Y?

Bakgrund: Employer Branding är ett relativt nytt begrepp som har börjat användas som en strategi inom Human Resource Management. Genom att utveckla ett Employer Brand kan or-ganisationer attrahera och behålla talangfull arbetskraft och på så vis säkra sin överlevnad. Det saknas emellertid forskning på hur Employer Branding kan användas i offentlig verksamhet för att attrahera den senaste generationen på arbetsmarknaden; Generation Y. Syfte: Öka förståelse för hur statliga myndigheter kan arbeta med Employer Branding för att attrahera Generation Y. Metod: Studien baseras på kvalitativ metod och har en fenomenologisk samt deduktiv forsk-ningsansats. Undersökningsdesignen var i form av en fallstudie. Nio semistrukturerade inter-vjuer har genomförts med respondenter på Bolagsverket, varav fyra intervjuer med personer som har inflytande över Employer Branding och fem med personer ur Generation Y. Teorier: "Employer Branding Predictive Model" Slutsatser: I studien visar att den statliga arbetsgivaren är attraktiv för Generation Y. Proble-matiken ligger i att det finns brister beträffande hur kommunikationen av arbetsgivarvarumärket ser ut externt. Utan en uttalad målgrupp och ett uttalat Employee Value Proposition blir den externa kommunikationen otydlig vilket minskar arbetsgivarens attraktionskraft hos potentiella arbetstagare. Attraktiviteten uppstår först när individen från Generation Y redan rekryterats in i organisationen.
