[pt] Este estudo investiga os comportamentos de processamento de um grupo de Brasileiros bilíngues instrucionados de português L1 e inglês L2, (n igual a 21), e um grupo de monolíngues de inglês norte-americano (n igual a 11) durante a sua compreensão de sentenças no present perfect (vs. simple past) em uma tarefa on-line de leitura auto-monitorada (Self-Paced Reading - SPR). Uma medida off-line, Tarefa de Julgamento de Aceitabilidade (Acceptability Judgment Task - AJT) foi utilizado como uma linha de base de conhcimento explícito da estrutura. Os resultados são comparados, qualitativamente, entre o grupo do monolíngue e bilíngue para investigar a sensibilidade, de cada grupo, às manipulações experimentais em tempo/aspecto, correspondência adverbial, e telicidade. O present perfect foi usado para os estímulos, pois é um tempo verbal do inglês adquirido mais tardiamente o que permite estudar as estratégias de processamento de bilíngues de nível mais avançado. Ambos os grupos foram capazes de reconhecer incongruências na atividade off-line. No entanto, o grupo monolíngue não foi sensível à condição de incongruência adverbial em tempo real, na atividade SPR. Por outro lado, o grupo bilíngue mostrou-se mais sensível a variável da incongruência adverbial, apresentando um comportamento que indica uma facilitação (automatização) de processamento da condição. O grupo monolíngue mostrou sensibilidade significativo às manipulações de telicidade em várias regiões do sintagma verbal. Diferenças entre os dois grupos foram observadas nas suas distribuições de tempos de leitura entre as condições em várias regiões da frase e elas são discutidas em termos de estratégias de processamento. Os monolíngues apresentaram efeitos de processamento integrativo no final da frase, os quais não são observados no grupo bilíngue. Atualmente, não há estudos com condições experimentais semelhantes que investiguem como os brasileiros bilíngues, avançados em inglês comportam na compreensão on-line de sentenças em inglês no present perfect. / [en] This study investigates the processing behaviors of a group of Brazilian bilingual students, instructed, advanced English students (n equal 21), and an English monolingual control group (n equal 11) during their comprehension of Present Perfect and Simple Past sentences in an on-line, self-paced reading (SPR) task. An off-line Acceptability Judgment Task (AJT) provides a baseline measure of explicit knowledge in order to validate the on-line results. The results are compared, qualitatively, between the bilingual and monolingual groups in order to investigate their sensitivity to experimental manipulations in Tense/Aspect, adverbial (Mis)match, and Telicity. The Present Perfect was used for the stimuli as it is a late-acquired feature of English which allows for the study of processing strategy of advanced level students. While both groups were able to recognize Mismatches off-line, monolinguals were not sensitive to the Mismatch condition in the on-line experiment. Surprisingly, the bilingual group showed more sensitivity to the adverbial Match variable, showing a processing facilitation in the Match condition as well as some mismatch sensitivity as well. The monolingual group showed significant effects for Telicity at multiple sentence regions. Some qualitative differences were seen between the two groups in their reading-time contours across the verb phrase. The monolinguals show within-group consistency across multiple conditions and signs of integrative processing (wrap-up) effects in their processing patterns which are not seen among the bilingual group. There are currently no studies with similar experimental conditions which investigate the on-line comprehension of the English Present Perfect with Brazilian Portuguese-English bilinguals in comparison to American English monolinguals.

No. of bitstreams: 1 Celso Frade.pdf: 1002866 bytes, checksum: 3aae61084839d164917eabb55ae16230 (MD5) Previous issue date: 2008-05-12 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The present perfect (PrP) is a complex issue for researchers and non-native speakers of English that has been studied from many different perspectives. This research aims at showing a description of the PrP in the language of news media and brings to light new insights into the teaching of English as a foreign language. Linguistic research on the nature of news stories has seen a great increase since the 1970s. So, the theoretical underpinning for the research provides a briefing of the state-of-the-art literature on the area that includes views on tense and aspect, Travaglia (1985) and Comrie (1985), the usage of PrP according to Schwenter (1994), Michaelis (1998), Engel & Ritz (2005)) and Nishiyama & Koenig (2005, 2006) and the meaning of discourse by Bell (1991), Fowler (1991), Halliday (1978, 1985) and Fairclough (1995, 1999). It, therefore, provides a clear picture of what has been researched on the uses of the PrP and its various functions in the language of news media. More specifically, the research reported here, which used the documentary research methodology (Sanghera:2002), uses examples from the data collected, which include 60 sample articles from the websites of quality British and American broadsheets, such as The Guardian and The Independent (UK), The New York Times and The USA Today (USA), the website from the TV news broadcasters, BBC and CNN as well as from weekly magazines such as Newsweek and Time, which serve the purpose of illustrating both the occurrence and usage of the PrP in different contexts. The period sampled refers to the years 2003-2008 and the range of topics and subgenres include hard news (current events and one-off unscheduled events called spot news) and soft news (longer featured articles on different issues which are not time-bound to immediacy). The research question investigated in the study is: what kind of functions emerge from the PrP samples in the language of news media? With respect to the question, the results indicate the PrP is a means of intensifying the information according to specific pragmatic needs the producer has while writing the piece of news. Therefore, this study brings an original contribution to the existing body of research on the expression of time in TESOL and Applied Linguistics / Esta pesquisa tem como objetivo descrever as funções do present perfect (PrP) que emergem do discurso jornalístico e traçar considerações discursivas e pedagógicas sobre essa questão. Optou-se pelo PrP, por ser um item da gramática da língua inglesa estudado sob diferentes perspectivas, por causa de sua complexidade tanto para os pesquisadores como para falantes não-nativos. A pesquisa lingüística acerca da natureza dos textos jornalísticos tem-se desenvolvido de modo abrangente, desde os anos de 1970, razão pela qual este trabalho, fundamentando-se na literatura da área, apresenta as visões de tempo verbal e aspecto, segundo Travaglia (1985) e Comrie (1985) e o uso do PrP, conforme os estudos de Schwenter (1994), Michaelis (1998), Engel & Ritz (2005) e Nishiyama & Koenig ( 2005, 2006). Esta revisão de literatura fornece uma perspectiva cronológica do que tem sido pesquisado sobre o uso do PrP e suas várias funções no discurso jornalístico, além de uma resenha dos autores sobre o discurso, dentre os quais, Bell (1991), Fowler (1991), Halliday (1978, 1985) e Fairclough (1995, 1999). Mais especificamente, fazendo uso da metodologia de pesquisa documental (Sanghera, 2002), analisam-se os dados coletados que incluem 60 textos de revistas e jornais da imprensa de qualidade americana e britânica, via mídia digital, The Guardian e The Independent (GB), The New York Times e The USA Today (EUA), os websites das redes de TV BBC e CNN e das revistas Newsweek e Time, com o propósito de ilustrar a ocorrência do PrP em diferentes contextos e assuntos. O período de coleta abrange os anos 2003 2008, e a diversidade de tópicos e subgêneros incluem Hard News (notícias atuais, como acidentes, e notícias acerca de política e diplomacia) e Soft News (artigos opinativos, não necessariamente relacionados a uma notícia recente). Em suma, procurou-se verificar que resultados indicam que o uso do PrP intensifica o valor da informação e atende às necessidades pragmáticas do produtor ao escrever o texto jornalístico e tentar dar uma contribuição original para as pesquisas que se direcionem à expressão da temporalidade no ensino de inglês como LE e para a Lingüística Aplicada no estudo do gênero notícia jornalística

Les travaux précédents menés en acquisition du langage soutiennent que les premières formes verbales de l’enfant sont limitées à l’expression de l’ici et maintenant (Weist, 1991). Cependant, une étude sur le développement du système verbal temporel en français (Parisse & Morgenstern, 2012) montre que l’enfant dispose d’une capacité à faire référence au passé de manière précoce, avant la production de marqueurs spécifiques dédiés à cet effet. Les études sur l’acquisition de l’aspect établissent une forte corrélation entre la production des verbes téliques et l’aspect perfectif (Shirai & Andersen, 1995), sans toutefois distinguer les marqueurs prétérit et present perfect. Slobin (1994) montre que le present perfect présente des fonctions communicatives spécifiques en lien avec l’expression du résultat et de l’expérience. À notre connaissance, aucune étude développementale de l’acquisition de ce marqueur n’a été menée jusqu’à présent. Nous nous proposons d’étudier les productions précoces de present perfect chez deux enfants britanniques dans le cadre des premiers usages des marqueurs de l’ici et maintenant et du décentrement dans le passé et de leurs valeurs dans le langage adressé à l’enfant. Nous avons mené des analyses quantitatives et qualitatives sur deux corpus longitudinaux denses d’interactions orales spontanées adulte/enfant (Tomasello, 2003). Nos résultats suggèrent que les productions précoces de present perfect résultent de la fréquence du marqueur trouvée chez l’adulte et du développement cognitif de l’enfant. L’étude des premiers usages du marqueur révèle que l’enfant s’appuie d’abord sur un état résultant visible à T0. Progressivement, l’enfant se sert de l’état résultant attaché à la production du marqueur pour verbaliser des attentes ou des intentions présupposées à T0. L’enfant demande ainsi à l’adulte de répondre à des besoins spécifiques exprimés dans la situation présente. / Previous studies in language acquisition have claimed that the verbal forms in early child language are limited to the expression of the here and now (Weist, 1991). However, a study of the verbal temporal system in French children’s speech (Parisse & Morgenstern, 2012) has shown that the children are able to refer to past events from an early age before they produce specific grammatical markers. Studies on the acquisition of aspect have established a strong correlation between the production of telic verbs and perfective aspect, without distinguishing between the present perfect and past tense. Slobin (1994) has shown that the first uses of the present perfect serve specific communicative functions that relate to the expression of result and experience. To our knowledge, no developmental study of the acquisition of the present perfect has been conducted so far. We conducted a study of how two British children use the present perfect in connection with their first uses of the markers referring to the here and now and their early productions of past tense. We examined the early uses of the markers in relation to the uses identified in the child directed speech in two dense oral corpora. Analyses based on qualitative and quantitative data were conducted on the adult and the child’s speech in the context of the interactions between the two (Tomasello, 2003). Our results suggest that the early productions of the present perfect result from the frequency of the marker found in the input and the cognitive development of the children. The study shows that they first rely on a visible resultant state in T0. Gradually, the children come to use the resultant state attached to the production of the marker to verbalise presupposed expectations or intentions in T0. By doing so, the children ask their caregivers to address specific needs that are expressed in the current situation.

In this essay I analyze the performative aspects relating to Marina Abramović's The Artist Is Present, which took place in spring 2010 at MoMA in New York, from the context of the artist and work, institution and documentation. In this performance work, for the duration of the exhibition, Abramović sits completely still opposite another chair where anyone from the audience may sit. The art arises through this participation. The audience are not only viewers, but also the observed, thus becoming part of the work and the negotiation of this exchange of living gazes. The performative pervades this work on multiple levels. The Artist Is Present reached a surprisingly large public, of over 500,000 visitors and continues to circulate in the form of blogs, documentary film and photography long after the exhibition duration. In order to conduct a performative analysis of The Artist Is Present I apply the theories of Peggy Phelan, regarding the relationships between the political and representative visibility in contemporary culture. Phelan's explanation of the unmarked field reveals the importance of the 'other' to see oneself. This is especially relevant in Abramović's performance which challenges and revolves around self reflection in the other. Phelan's theories are also pertinent in analyzing what Abramović as the performer and her work create for re-negotiations around positions and the gaze. The assertions of Carol Duncan in considering the Art Museum as a place of ritual are applied to the ritualistic context of The Artist Is Present, which may well build up a form of liminality. Duncan's claims of the museum as ritual in combination with Phelan's theories provide interesting grounds to further investigate the effect and eventual mythology of the performance work and artist. How do these contexts of institution, documentation, artist and art, which I propose contribute to a kind of myth creation, operate in a ritualized performance art work? This essay analyses these contexts together in order to find a connection between the performative aspects and the effect that they have on the viewer and receiver, which have contributed to the public success of this exhibition. Despite that we now live in an era of reproduction, perhaps the wishes of our era still revolve around a cult value? That even in this post industrial age of reproduction, new needs are recreated for mythology and cult? Or can it be that the reverse is true, that the rites and symbols speak to us before the mythology has fully arisen?

This study is focused on the transfer accounts and the prototype accounts, and examines aspect through looking at L1 Swedish learners of Spanish who are at early stages of acquisition. The prototype accounts postulate that adult learners will acquire the most prototypical forms of a grammatical feature first, and then, as proficiency increases, less prototypical features, called extended meanings, will be acquired incrementally (Shirai & Andersen, 1995, Geeslin & Fafulas, 2012). The transfer accounts claim that all grammatical features of the L1 will transfer at initial stages, and that this will either facilitate or impede acquisition, depending on if there are structures that are realized differently or similarly in the L1 and in the L2 (Kellerman, 1979, Gass & Ard, 1984, Schwartz & Sprouse, 1996, Gabriele et al., 2015). The study uses the stimuli and experiment used in Gabriele et al. (2015), a study that tested L1 English learners of Spanish and found evidence that support the transfer accounts. Results from the present study shows positive evidence of L1 transfer, which is taken as support for the transfer account. The results are not compatible with the prototype accounts. A finding of a marginal difference might be indicative of L2 transfer, which is also taken as evidence for the transfer accounts.

Climate change has already had major impacts on our planet. Loss of sea ice, accelerated sea level rise and longer, more intense heat waves, are a few of these. Many scientists believe that a continued climate change will have even more severe impact on our planet. To tackle the climate change, a fast transition towards renewable energy sources is necessary. One of the most promising sources of renewable energy is solar energy. To achieve the goal of making the world more reliable on solar energy, various actors try to improve the technology and the financial basis regarding this way of extracting energy. In this transition, calculations have to be as accurate as possible, in order to benefit from them when installing solar panels. This bachelor thesis intends to create an investment model for solar plants and an optimization of the plant’s size based on net present value. The model is built in Microsoft Excel, and factors such as electricity prices, electricity production/consumption and several others are taken into account. Based on the comparison with a case study and the calculations made by the model, the results suggest a reliable model. On behalf of Herrljunga Elektriska AB, the model is created to help them generate reliable and fast investment calculations, which will hopefully bring value to their business.

This master thesis has been performed in association with Blekinge Institute of Technology and in collaboration with the company Dynapac Compaction Equipment AB. The thesis aims to investigate how Discrete Event Simulation (DES) can be used for value and sustainability design concept assessments in early design stages. The research is made by investigating the example of simulating the lifecycle of a double drum asphalt compactor. The model is created in the computerbased DES software Simio LLC, where the captured data of the compactor´s lifecycle performances are linked to a Net Present Value (NPV) model and a sustainability assessment. The model is then further explored and evaluated in the Decision Arena, located at Blekinge Institute of Technology.  The simulated model is created to approach a ‘lifelike’ lifecycle of the machine, containing the compactor´s ordinary usage in road construction. This includes operations in sidewalk, parking lot and pothole repair scenarios. The model contain service, maintenance, transport, workers, resource sharing and more. The model is connected to MS Excel to transfer data. The life cycle performances are captured in the model and used to estimate the cost parameters of energy -, water -, maintenance -, service - and transportation energy cost within the NPV model. The CO2 – emission for fuel consumption and transport, together with the total water consumption in the sustainability assessment.  The outcome of the thesis showed that the method gave good results for developing new design configurations in the early phases in product development. The method could support designing towards sustainable and long-term solutions and collaborations over the sectors (i.e. between stakeholders, engineers, designers, non-experts and more). The outcome in the specific case resulted in successfulness of capturing all lifecycle performances of the machine and linking them to the mentioned parameters. The research question is, however, generic and the investigation for the specific case study uses assumptions and up- and down scaled data to protect the company secrecy. For future work, the method together with Internet of Things (IoT), Digital Twin or Industry 4.0 could be in high interest to investigate further. / Detta examensarbete har blivit utfört i association med Blekinge Tekniska högskolan och i samarbete med företaget Dynapac Compaction Equipment AB. Syftet med projektet är att undersöka hur diskret händelsesimulering (DES) kan användas för värde - och hållbarhets bedömning för olika designkonfigurationer, i tidiga skeden av produktutvecklingen. Arbetet är utfört genom att tillämpa exemplet av att simulera livscykeln för en asfaltsvält med dubbla trummor. Simuleringsmodellen är framställd genom det databaserade DES programmet Simio LLC, där utdata för maskinens livscykelprestanda tas fram och kopplas till en Net Present Value (NPV) modell och en hållbarhetsdömning för maskinen. Simuleringsmodellen utforskas och bedöms sedan vidare i ’Decision Arena’ på Blekinge Tekniska Högskola.  Den simulerade modellen är framställd för att eftersträva en verklighetstrogen livscykel av maskinen, innehållande dess vanliga användningsområden inom vägarbete. I livscykeln inkluderas operationer av trottoarer, parkeringsplatser och reparationer av hål i vägbanor. Modellen innehåller även service och underhåll, transport, arbetare/anställda, resursdelning med mera. Modellen är kopplad till MS Excel för att föra över in- och utdata mellan programmen. Maskinens livscykelprestanda är hämtat från modellen och använt till att uppskatta kostnadsparametrarna för energi, vatten, underhåll, service och energi under transport i NPV – modellen. Maskinens CO2 – utsläpp för bränsleförbrukning och transport, tillsammans med vattenkonsumtionen i hållbarhetsbedömningen. Arbetet visar på goda resultat för att utveckla nya desginkonfigurationer i de tidiga skedena inom produktutveckling. Metoden kan stödja utformning mot hållbara och långsiktiga lösningar, samt förstärka samarbeten över sektorerna (dvs. mellan intressenter, ingenjörer, designers, icke-experter med mera). Utfallet för det specifika fallet resulterade i framgång med att fånga upp maskinens livscykelprestanda och koppla dessa till de ovan nämnda parameterana. Forskningsfrågan är dock generell och utredningen för den specifika fallstudien använder uppskattningar och upp- och nerskalade data för att skydda företagets sekretess. För framtida arbete, kan metoden tillsammans med Internet of Things (IoT), Digital Twin och Industry 4.0 vara av stort intresse för att undersöka.

Bakgrund: Amyotrofisk lateral skleros är en sjukdom som innebär att de motoriska nervcellerna i hjärnan och ryggmärgen som aktiverar den viljestyrda muskulaturen förtvinar och bryts ner. Konsekvenser av detta är minskad muskelkraft och förlamning. Amyotrofisk lateral skleros är en obotlig sjukdom vilket gör det intressant att studera hur dessa personer erfar hopp. Syfte: Att beskriva hopp hos personer med amyotrofisk lateral skleros. Metod: En kvalitativ studie med deduktiv inriktning genomfördes där dokumentärer analyserades. Resultat: Olika hopp beskrevs vid olika tillfällen under sjukdomsförloppet. Framträdande i studien var att de flesta personer beskrev en önskan och ett hopp om att hitta ett botemedel tidigt i sjukdomsförloppet. När detta inte längre framstod som lika självklart blev hopp i form av socialt stöd och hopp om att leva i nuet mer framträdande i personernas beskrivningar. Slutsats: Personer som drabbas av amyotrofisk lateral skleros initialt hoppas starkt på att finna ett botemedel, men sedan kretsar hoppet mer kring de sociala relationerna. Ur klinisk synpunkt är det viktigt att som vårdpersonal bli mer medvetna om hur dessa personer upplever hopp för att möjliggöra att den egna identiteten och förmågan bevaras. / Background: Amyotrophic lateral sclerosis is a disease in which the motor nerve cells in the brain and spinal cord, that activates the involuntary muscles, atrophy and breaks down. Consequences of this are decreased muscle strength and paralysis. It is an incurable disease which makes it interesting to study these people and how they experience hope. Aim: To describe hope in people with amyotrophic lateral sclerosis. Method: A qualitative study of deductive orientation was conducted where documentaries were analyzed. Results: Different types of hope were described at various times during the course of the disease. It was prominent that most people described a wish and a hope to find a cure early in the disease. Gradually hope in the form of social support and hope to live in the present appeared as more prominent. Conclusion: People who suffer from amyotrophic lateral sclerosis initially strongly hopes of finding a cure, but then the hope revolves more around social relationships. From a clinical standpoint, it is important that healthcare professionals become more aware of how these people experience hope to enable their own identity and ability preserved.

Master of Agribusiness / Department of Agricultural Economics / Allen M. Featherstone / The cost of energy is a major concern for the United States and its citizens. With domestic demand at all time highs, the need for renewable fuels has become a key in reducing our countries reliance on imported energy. It is important for the U.S. to examine the feasibility of producing its own energy from renewable resources that can be grown domestically. Along with the potential financial gains from renewable fuels, the ability to control the supply of energy for the U.S. is also very important. With the amount of oil imported by the U.S., the ability to produce more of our nations needs and not be forced to rely on other countries could be important for our country moving forward. With the political unrest in many oil producing areas, the security of energy independence is a goal for the U.S. This study uses United States Department of Agriculture, Pro Exporter, Advance Trading, and other statistical sources to analyze the economic feasibility of an ethanol plant near Des Moines, IA. It looks at the available supply of corn in the area as well as the production of ethanol and distillers grains. An increase in the price of imported oil does not necessarily results in an economically viable ethanol plant. Many variables go into the economic viability of an ethanol plant and consumers will still buy the low cost good, and that may be imported energy. Some of these variables affecting economic viability include corn price and availability, denaturant price, natural gas price, ethanol demand and distillers grains demand. With the push for cleaner air and a cleaner environment, ethanol is also used as a gasoline additive to reduce emissions. As more states regulate a higher inclusion rate of ethanol, this will continue to create greater demand. A 100 million gallon ethanol plant is an economically viable investment in the Des Moines area, but when looking at the sensitivity tests, the better investment option if investors want to enter the ethanol industry, is to buy an existing ethanol plant.

Master of Agribusiness / Department of Agricultural Economics / Jeffery R. Williams / The objective of this thesis is to conduct a net present value analysis of installing a solar power generation system on company owned turkey grow out ranches. This research project provides information regarding the systems power production capacity, investment cost, maintenance requirements, amount of energy saved, useful life of the equipment, marginal state and federal tax brackets for the company. The investment cost of the system includes the price of the equipment and installation service. Many of the system costs may be offset by rebates, tax credits and grants from various government agencies. These must also be included in the financial analysis as they can greatly affect the financial viability of the project. The system is projected to have a useful life of 30 years with an inverter replacement planned for year 15. Four scenarios were evaluated using two levels of rebates and two electrical rate inflation levels. The evaluations conducted showed positive after tax NPV evaluations on three of four scenarios reviewed with the most financially attractive options available when the rebates, tax credits and grants were maximized. This was the case at both electrical rate inflation scenarios. These same scenarios produced favorable results when looking at reduction of live production ranch costs. The system effectively locked in electrical rates below current rates for the 30 year life of the system. This reduced ranch live production cost by as much as 11.73 percent. It also gives the company an advantage over the competition when used as a marketing tool due to the use of green technology in company production practices.
