Integrating recommender systems into domain specific modeling tools

Nair, Arvind 09 March 2017 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / This thesis investigates integrating recommender systems into model-driven engineering tools powered by domain-specific modeling languages. The objective of integrating recommender systems into such tools is overcome a shortcoming of proactive modeling where the modeler must inform the model intelligence engine how to progress when it cannot automatically determine the next modeling action to execute (e.g., add, delete, or edit). To evaluate our objective, we integrated a recommender system into the Proactive Modeling Engine, which is a add-on for the Generic Modeling Environment (GME). We then conducted experiments to both subjective and objectively evaluate the enhancements to the Proactive Modeling Engine. The results of our experiments show that integrating recommender system into the Proactive Modeling Engine results in an Average Reciprocal Hit-Rank (ARHR) of 0.871. Likewise, the integration results in System Usability Scale (SUS) rating of 77. Finally, user feedback shows that the integration of the recommender system to the Proactive Modeling Engine increases the usability and learnability of domain-speci c modeling tools.

[pt] ESTRATÉGIA COMO FATOR DETERMINANTE DE DESEMPENHO NA INDÚSTRIA AUTOMOBILÍSTICA BRASILEIRA / [en] STRATEGY AS KEY PERFORMANCE FACTOR IN BRAZILIAN AUTOMOTIVE INDUSTRY

BRUNO CASTELLO MEMORIA 24 September 2015 (has links)
[pt] Este trabalho tem como objetivo observar a possível relação teórica entre grupos estratégicos da indústria automobilística brasileira e o desempenho das empresas pertencentes a estes grupos estratégicos. Para cumprir este objetivo, foram analisadas 30 montadoras de automóveis, identificando os grupos estratégicos formados, utilizando a tipologia de Michael Porter como base. Após a identificação das estratégias competitivas foi realizada análises sobre o desempenho dos grupos, observando como os grupos estratégicos se apresentam dentro desta indústria. Os dados foram analisados estatisticamente (Z-score, Shapiro-Wilks, análise fatorial, K-means clusters, ANOVA e MANOVA), permitindo análises mais consistentes sobre o coalinhamento estratégico das empresas da indústria em questão. Como resultados, foram encontrados cinco grupos estratégicos, com diferenças significantes entre os seus desempenhos médios para algumas variáveis dependentes, especialmente para a variável Satisfação dos clientes. Esta diferença entre o desempenho médio dos grupos estratégicos indica a importância do estudo das estratégias competitivas das empresas de determinada indústria, sugerindo possível relação teórica entre a estratégia e o desempenho. / [en] This study aims to evaluate the possible theoretical relationship between strategic groups of the Brazilian automobile industry and the performance of companies belonging to these strategic groups. To achieve this goal, were analyzed 30 car assemblers companies, identifying strategic groups, using Michael Porter s typology as a base. After the identification of competitive strategies, analysis was conducted on the performance of the groups, observing how the strategic groups present within this industry. Data were statistically analyzed (Z-score, Shapiro-Wilks, factor analysis, K-means clustering, ANOVA and MANOVA), allowing more consistent analyzes of the strategic co-alignment of industry companies concerned. As a result, five strategic groups were found, with significant differences between their average performances for some dependent variables, highlighting the Consumer Satisfaction variable. This difference between the average performances of strategic groups indicates the importance of studying the competitive strategies of the particular industry companies, suggesting a possible theoretical relationship between strategy and performance.

[pt] O mercado Pet respondeu em 2015 por um faturamento superior a 100 bilhões de dólares no mundo, sendo o Brasil responsável pelo terceiro maior valor – 18 bilhões de reais, ou um crescimento de 7,6 porcento em relação a 2014. O segmento veterinário, responsável por 8 porcento deste faturamento, teve um aumento considerável nos últimos anos, passando por um processo de profissionalização do setor. Onde antes havia pequenos consultórios familiares, hoje as clínicas e hospitais estão crescendo, se especializando e tornando-se empresas genéricas. Diante deste cenário, e frente a clientes cada vez mais exigentes e bem informados, vem aumentando o esforço dos gestores desses negócios para tornar suas empresas eficientes e lucrativas. Este trabalho visa identificar as principais forças atuantes no mercado dos estabelecimentos veterinários e avaliar as estratégias genéricas adotadas pelas empresas para terem sucesso neste cenário, de acordo com a metodologia de Michael Porter. Assim, foram entrevistados gestores de sete clínicas veterinárias localizadas no Estado do Rio de Janeiro. Os resultados mostram que os investimentos em inovação, infraestrutura e mão de obra especializada esbarram em entraves do setor, como dificuldade da legalização da mão de obra, pouco conhecimento de gestão por parte dos recém-formados e burocracia complexa, seja municipal, de vigilância sanitária ou determinada pelo Conselho Federal de Medicina Veterinária. Embora os entrevistados relatem que o setor carece de estratégia de forma geral, suas empresas tem obtido sucesso através da aplicação de uma estratégia com escopo estreito e diferenciação. / [en] The Pet market accounted in 2015 for a turnover of more than 100 billion dollars in the world, with Brazil accounting for the third largest value - 18 billion Reais, or 7.6 percent growth compared to 2014. The veterinarian segment, responsible for 8 percent of these revenues, has increased considerably in recent years, through an industry professionalization process. Where once there were small family practices, clinics and hospitals, today they are growing, specializing and becoming increasingly competitive. In this scenario, and facing customers increasingly more demanding and well informed, managers have been making efforts to transform their businesses in more efficient and profitable firms. This work aims to identify the main forces acting on veterinary establishments market and evaluate the competitive strategies adopted by these companies to be successful in this scenario, according to the methodology of Michael Porter. Therefore seven managers of veterinary clinics in the state of Rio de Janeiro were interviewed. The results show that investments in innovation, infrastructure and skilled labor stumbles in industry barriers such as the difficulty of labor legalization, scarce management skills by the newly formed and complex bureaucracy, whether municipal, health surveillance or determined by the Federal Council of Veterinary Medicine. Although respondents report that the sector lacks a general strategy, there businesses have been successful by applying a strategy with narrow scope and differentiation.

Kompetensers betydelse för ledarskapet : Att tänka på vid rekrytering av chefer / Things to consider when recruiting managers

Svalland Fridholm, Tilde, Hjerdt, Alexandra January 2023 (has links)
Önskvärda ledarskapskompetenser är ett väl utforskat område, dock finns det relativt lite forskning som berör ämnet inom industrin i Sverige. Syftet med denna studie var därför att få en ökad förståelse för vad medarbetare som är verkande i en global industriorganisation upplever som viktiga kompetenser för ett optimalt ledarskap. Studien bygger på empiri från nio kvalitativa semistrukturerade intervjuer med anställda från den globala industriorganisationen. Resultatet visar att chefer som besitter både generisk- och yrkeskompetens visar sig tillsammans uppnå det mest optimala ledarskapet. Slutsatsen som dras är att medarbetarna upplever en kombination av generisk- och yrkeskompetens som mest gynnsamt och att de ej går att styrka att den ena kompetensen är viktigare än den andra. Ytterligare en annan slutsats som denna studie kan bidra med är en ny synvinkel till teorin gällande uppdelningen mellan generisk- och yrkeskompetens. Empirin i studien har visat en sammanslagning av både generisk- och yrkeskompetens och menar att om dessa särskiljs helt åt kan det uppvisa en missvisande bild av kompetenserna. / Desirable leadership skills are a well-explored area, however, there is relatively little research on the subject within industry in Sweden. The purpose of this study was therefore to gain an increased understanding of what employees who are working in a global industrial organization experience as important competencies for optimal leadership. The study is based on empirical evidence from nine qualitative semi-structured interviews with employees from the global industrial organization. The result shows that managers who possess both generic and professional competence together achieve the most optimal leadership. The conclusion that is drawn is that the employees experience a combination of generic and professional competence as the most favorable and that they cannot prove that one competenceis more important than the other. Another conclusion that this study can contribute is a new point of view to the theory regarding the division between generic and professional competence. The experience in the study has shown an amalgamation of both generic and professional competences and believes that if these are separated completely, it can present a misleading picture of the competences.

[pt] COMUNICAÇÃO POLÍTICA, MÉTODOS COMPUTACIONAIS E PANDEMIA: OS TRÊS PRIMEIROS MESES DA COVID-19 NO BRASIL E SEU PROCESSO DE ENQUADRAMENTO NO TWITTER / [en] POLITICAL COMMUNICATION, COMPUTATIONAL METHODS AND PANDEMIC: THE FIRST THREE MONTHS OF COVID19 IN BRAZIL AND ITS FRAMING PROCESS ON TWITTER

LEONARDO MAGALHAES FIRMINO 17 March 2022 (has links)
[pt] A pesquisa tem como objetivo estudar a variação temporal de enquadramentos genéricos e específicos sobre saúde no contexto da pandemia de covid-19 no Brasil. Se trata de um estudo de caso realizado no Twitter sobre o tema da saúde (n = 31.339.922) entre 15 de março e 15 junho de 2020. Como categorias analíticas, se estudaram 3 frames genéricos e 3 específicos sobre saúde em contextos de epidemias. Os frames genéricos foram operacionalizados de forma dedutiva: conflito, atribuição de responsabilidade e moralidade (SEMETKO; VALKENBURG, 2000). Os frames específicos foram operacionalizados com o método indutivo (DE VREESE, 2005): consequências da pandemia, medidas de contenção e métodos de tratamento. Os tweets foram classificados automaticamente mediante um método computacional dictionary based, garantindo a confiabilidade, a validez e a reprodutibilidade (KRIPPENDORFF, 2011; SAMPAIO; LYCARIÃO, 2018). Foi realizada uma série temporal para observar a variação diária da evocação de cada quadro nos 93 dias estudados. Foi construída também uma rede temporal de usuários conectados mediante menções, retweets e respostas, sobre a qual foi calculada a métrica PageRank para medir a sua influência diária sobre a rede. Foram selecionados os dez atores mais proeminentes segundo o seu PageRank na data de maior pico de cada frame da série temporal. Finalmente, foram sistematizadas as informações sobre o contexto de análise e sobre o clima de opinião no Brasil mediante surveys representativos da população brasileira com frequência diária (n = 1.800, ME = mais ou menos 2 por cento, IC = 95 por cento). Os resultados da pesquisa apontam que a ordem de evocação dos frames, do mais ao menos proeminente, foi: conflito, atribuição de responsabilidade, consequências da pandemia, moralidade, medidas de contenção e métodos de tratamento. Em especial, os quadros do conflito, da atribuição de responsabilidade e das consequências da pandemia estiveram fortemente relacionados a um enquadramento negativo, episódico e de interesse humano dos tweets. Por outro lado, os demais frames (moralidade, medidas de contenção e métodos de tratamento) priorizaram enquadramentos temáticos, cujas implicações eram preponderantemente de natureza mais social e menos individual. Se destaca também a significativa presença de perfis anônimos entre os Top10 usuários de cada frame, assim como militantes, especialistas em saúde, influenciadores digitais, jornalistas, órgãos de mídia, políticos e perfis de outra natureza. Por fim, no que se refere ao estudo das condições que estão associadas aos picos mais altos de evocação dos frames genéricos e específicos da série temporal, foi observado um fenômeno que se definiu como sincronização do enquadramento. Se define a sincronização do enquadramento como um fenômeno de ajuste coletivo da frequência ativação em rede de um determinado frame por meio da interação entre os indivíduos e influenciado por quatro fatores: contexto, sucessão de eventos associados, clima de opinião e combinação entre frames e temas. / [en] The research aims to study the temporal variation of generic and specific frames about health in the context of the Covid-19 Pandemic in Brazil. It is a case study conducted on Twitter about health (n = 31,339,922) between March 15 and June 15, 2020. As analytical categories, 3 generic and 3 specific frames about health in epidemic contexts were studied. The generic frames were operationalized deductively: conflict, attribution of responsibility and morality (SEMETKO; VALKENBURG, 2000). The specific frames were operationalized with the inductive method (DE VREESE, 2005): consequences of the pandemic, containment measures, and treatment methods. The tweets were automatically classified using a dictionary-based computational method, ensuring reliability, validity, and reproducibility (KRIPPENDORFF, 2011; SAMPAIO; LYCARIÃO, 2018). A time series was performed to observe the daily variation of the evocation of each frame in the 93 days studied. A temporal network of users connected through mentions, retweets, and replies was also performed, on which the PageRank metric was calculated to measure their daily influence on the network. The ten most prominent actors were selected according to their PageRank on the peak date of each frame of the time series. Finally, information on the context of analysis and on the climate of opinion in Brazil was systematized through representative surveys of the Brazilian population with daily frequency (n = 1,800, ME = plus–minus 2 percent, CI = 95 percent). The results indicate that the order of evocation of the frames, from most to least prominent, was conflict, attribution of responsibility, consequences of the pandemic, morality, containment measures, and treatment methods. In particular, the frames of conflict, attribution of responsibility, and consequences of the pandemic were strongly related to a negative, episodic, and human interest framing of the tweets. On the other hand, the other frames (morality, containment measures and treatment methods), prioritized thematic framings, whose implications were preponderantly of a more social and less individual nature. Also noteworthy is the significant presence of anonymous profiles among the Top10 users of each frame, as well as activists, health experts, digital influencers, journalists, media organizations, politicians, and profiles of another nature, such as fandoms and satirical. Finally, regarding the study of the conditions that explain the highest peaks of evocation of the generic and specific frames in the time series, a phenomenon that was defined in this thesis as framing synchronization was observed. Framing synchronization is defined as the phenomenon of collective adjustment of the frequency of network activation of a given frame through interaction between individuals and influenced by five factors: context, succession of associated events, climate of opinion, and the combination of frames, and issues.

Förbättring av nedgångslucka på en segelbåt / Enhancement of the companionway on a sailing yacht

Hagberg, Philip, Henriksson, Jesper January 2018 (has links)
Linjett Segelbåtar konstruerar och producerar högkvalitativa  segelbåtar på Rosättravarvet. Detta arbete syftar till att presentera en bättre mekanisk lösning till den nedgångslucka som Linjett har idag. Förbättringen består i att sänka produktionskostnaderna, underlätta montering och service men framförallt öka livslängden på mekanismen. Nedgångsluckan är den vertikala ”dörr” som skiljer utsidan från insidan på en segelbåt. I Linjett’s befintliga lösning så skjuts luckan ned i en balja under durken och försvinner undan på ett väldigt smidigt sätt. Tack vare en gasfjäder görs den annars ganska tunga luckan viktlös och kan lämnas halvöppen vilket kan vara väldigt praktiskt, det är en typ av funktion som den nya lösningen måste bibehålla. Arbetet har följt en generisk utvecklingsprocess. Koncept från en idégenerering har ställts mot varandra med hjälp av en pughmatris och en multiomröstning. Det vinnande konceptet har sedan förbättrats i en iterativ process för att uppfylla målen i så hög utsträckning som möjligt. Under vidareutvecklingen har fokus legat på att minimera antal komponenter genom DFA (Design For Assembley). För att motivera lösningen har monteringsscheman ställts upp och kompletterats med en självkostnadskalkyl. Dessa detaljstuderas och utvärderas för att agera beslutsunderlag till Linjett. Den presenterade lösningen använder konstantkraftsfjädrar för att bära upp luckans vikt. Dessa fjädrar ger lång livslängd i dessa utsatta miljöer och har ett förhållandevis lågt inköpspris. / Linjett Segelbåtar constructs and produces high quality sailing yachts at Rosättravarvet. This rapport aims to enhance the mechanical solution of the companionway door that Linjett is using. The enhancement consists in lowering production costs, simplify the mounting and service but most important, raise the lifetime of the mechanism. The companionway door is what separates the outside from the inside on a sailing yacht. Linjett has a special solution were the companionway door slides in under the cockpit floor and disappears in a clever way. Thanks to a gas spring the otherwise heavy door becomes weightless and can be left at any desired height which can come in handy. This is one of the function that the new solution must maintain. The work has followed a generic developmentprocess. Concepts from a brainstormingsession have been evaluated and compared in a pughmatris and a multivote. The winning concept has then been improved in a iterative process to fulfill the goals in the best way possible. During the enhancement of the concept there has been a strive to minimize the number of components throughout DFA (Deisgn for Assembley) To motivate the solution a mounting schedule was produced which in turn were complemented by a cost price calculation. These were studied in detail and evaluated to create a basis for decision making to Linjett. The presented solution uses constant force springs to carry the weight of the companionway door. Springs of these type provide long lifetime in these harsh conditions and is reasonably priced.

Handelskvarteret Valvet : En fallstudie om konkurrensstrategier vid etablering av nytt handelskvarter / The Valvet shopping district : A case study on competition strategies when establishing a new trading district

Gottmarsson, Jessica January 2021 (has links)
Karlstad står inför sin största stadsomvandling i modern tid. Fler bostäder, utökad och förbättrad stadskärna, förnyad infrastruktur för både tåg-, buss-, bil-, gång- och cykelresenärer är delar av kommunens vision inför 2030. Handelsindex tyder på fortsatt goda förutsättningar till konsumtion. En efterlängtad satsning på ett nytt handelskvarter mitt i centrala Karlstad får äntligen startbesked och en ny modern handelsplats med inslag av kulturhistoriskt intressanta lokaler tar vid. En saluhall tillkommer, något man trodde var efterlängtat och därmed skulle locka besökare. Men utfallet visade sig bli annorlunda. Med höga förväntningar invigdes år 2016 den sista etappen av handelskvarteret Valvet. Kort efter öppning har förhoppningarna om Valvets nysatsning för centrumutvecklingen i staden raserats, den respons man förväntade och det kundflödet man räknade med uppstod aldrig. År 2017 tar man beslutet att avveckla handelsverksamheten för att istället satsa på restaurangverksamhet och nöjen i lokalerna. Syftet med arbetet är att studera källorna till varför etableringen av Handelskvarteret Valvet inte lyckades leva kvar. Michael Porters konkurrensstrategi, femkraftsmodellen, samt Porters generiska basstrategier utgör det teoretiska ramverket och för att berika den kvalitativa studien har intervjuer gjorts med personer i direkt anknytning till projektet om Valvet. Annan datainsamling har skett via dokument från Karlstad kommun och också publicerade artiklar i värmländska tidskrifter. Resultatet visar att på att det finns flera orsaker till att etableringen inte lyckades i den utsträckning man först önskade. Klimatet har förändrats i centrum i takt med ökad e-handel och externhandel, konkurrensen har således ökat. Samtidigt har ett bristfälligt kundunderlag skapat en övertro på en av huvudaktörerna, kundflödet blev bristfälligt och påverkade hela handelskvarteret negativt. Värdeskapande faktorer har varit svaga, däribland utformning, synergieffekter och hyresgästmixen. Antydan till en förskjutning i centrum, från konsumtion till upplevelser, har möjligen också haft en inverkan vid etableringen. / Karlstad faces its greatest urban transformation in modern times. More housing, expanded and improved city centers, renewed infrastructure for train, buses, cars, pedestrians and cyclists are all part of the municipality's vision by 2030. The trade index indicates continued favorable conditions for consumption. An anticipated investment in a new commercial district in the center of Karlstad is finally launched, and a new modern shopping center with elements of historical- and cultural interesting areas is taking place. A market hall is added, something that was thought to be wished-for and would attract visitors. But the outcome turned out to be different. With high expectations in 2016, the final stage of the shopping center Valvet was opened. Soon after opening, the hopes for Valvet's new initiative for city center development were gone. The response expected and the anticipated customer flow never occurred. In 2017, the decision is taken to discontinue the shopping center, to instead change the concept into restaurants and a giant event park. The purpose of this work is to study the sources of why the establishment of Valvet shopping center failed. Michael Porter's competitive strategy, the five forces analysis model, constitutes the theoretical framework. In order to enrich the qualitative study, interviews have been made with people directly related to the project Valvet. Other data collection has been carried out via documents from the municipality but also published articles in Värmländska newspapers. The result shows that there are several reasons why the establishment failed to the extent that was first desired. The climate has changed in the city center in line with increased e-commerce and external trade, competition has thus increased. At the same time, a deficient customer base has created a superstition about one of the main players, the customer flow became deficient and had a negative effect on the entire trading district. Value-creating factors have been weak, including design, synergy effects and the tenant mix. The hint of a shift in the center, from consumption to experiences, may also have had an impact on the establishment.
