O propósito deste estudo foi avaliar a acurácia do exame de tomografia computadorizada multislice (TCM) e tomografia computadorizada por feixe cônico (TCFC) na identificação de lesões simuladas em mandíbula, em situações com e sem a presença de artefatos metálicos, em diversos protocolos de observação. Foram realizados exames de TCM e TCFC de mandíbulas secas, nas quais foram executadas perfurações simulando lesões. As imagens foram realizadas em dois momentos: na presença e na ausência de restaurações dentárias metálicas. Dois observadores, previamente calibrados, observaram as imagens avaliando-as quanto à presença ou ausência de lesão, número de lojas das lesões e a existência ou não de invasão medular. Os mesmos utilizaram programas de manipulação de imagens instalados em estações de trabalho independentes, para reconstruir as imagens nos seguintes protocolos de avaliação: axial, sagital + coronal, 3D, conjunto (axial+sagital+coronal+3D) e parassagital. A sensibilidade e especificidade (validade) da tomografia computadorizada multislice (64 cortes) (TCM) e da tomografia computadorizada por feixe cônico (TCFC) para diagnóstico de lesões ósseas (simuladas) em mandíbula, utilizando estação de trabalho independente foram demonstradas à medida que os valores encontrados foram superiores a 95% desde que com o protocolo de observação adequado. A influência de artefatos dentários metálicos foi pouco significativa na interpretação de lesões ósseas mandibulares, já que os valores de acurácia nas análises com e sem artefato foram bastante próximas. Os protocolos com aquisição por TCM sofreram mais influência dos artefatos do que os adquiridos por TCFC (valores sutilmente menores), exceto nas reconstruções em 3D, em que as originadas de aquisição por TCFC, apresentaram valores menores de acurácia. O melhor protocolo de pós processamento para interpretação de lesões ósseas simuladas foi o denominado RMP+3D. O protocolo que apresentou os piores resultados foi o que utilizou as reconstruções parassagitais. / The purpose of this study was to evaluate the accuracy of multislice computed tomography (MSCT) and cone-beam computed tomography (CBCT) in identification of simulated mandibular lesions in situations with and without metallic artifacts in several observation protocols. MSCT and CBCT examinations were performed in dry mandibles, in which holes were performed simulating lesions. The images were taken in two stages: in the presence and absence of metal dental restorations. Two observers, previously calibrated, observed the images by evaluating the images for the presence or absence of lesion, loci number and whether there were medullary invasion. Observers used image manipulation softwares, installed on independent workstations, to reconstruct the images in the following evaluation protocols: axial, sagittal + coronal, 3D, sets (axial+ coronal + sagittal + 3 D) and parasagittal. The sensitivity and specificity of MSCT (64 slices) and CBCT for diagnosis of simulated bone lesions in the mandible, using independent workstation were demonstrated as the values obtained were greater than 95% using the appropriate observation protocol. The influence of dental metallic artifacts was negligible in the interpretation of mandibular bone lesions, since the values of accuracy in the analysis with and without artifact were quite close. The images acquired with MCT suffered more influence of artifacts than the protocols acquired by TCFC, although the values were all high and quite close. Except for 3D reconstructions, which originated from the CBCT, showed the lowest accuracy. The best protocol for post-processing and interpretation of simulated bone lesions was called RMP +3 D. The protocol that showed the worst results was parasagital.

The issue of successful implementation of strategic organizational change is not sufficiently addressed in the literature of organizational change even though there is unanimity in reporting a high rate of failure. Moreover, attempts to provide supportive guidelines that enhance implementation success are meager and their validity in nonwestern contexts is disputed. Thus, the present study tried to address the question of how a strategic organizational change can be successfully implemented by developing an implementation model within the context of Ethiopian commercial banks. In Ethiopia, commercial banking is exclusively reserved for nationals. This makes the setting a typical national context from where two commercial banks were included in the present study through maintaining maximum variation in ownership structure. Embedded in each bank, cases of teams which were established to redesign a specific type of business process were identified to theoretically sample participants for the indepth interviews. Applying an inductive multiple case study strategy, a combination of within-case and cross-case analyses were employed with the support of the ATLAS.ti software. As a result, theoretical propositions were made and an implementation model for strategic organizational change was developed by taking the context of commercial banks in Ethiopia into consideration. The findings indicate that national and organizational contexts demand contextualized approaches to implement strategic organizational change. Although several concepts which are documented in the extant literature were confirmed, original propositions are also made by the present study. A triple helix of initiating, designing, and implementing were emerged as inseparable components of the proposed implementation model for strategic organizational change in a context where cognitive and technical readiness is ensured. / Business Management / DBL

Managing this relationship capability with partners has been the focus of study of many researchers, because to align the proposed goals among partners is one of the challenges to have success in alliances, and many fail in this management process. In this way, the aim of this research was to determine the role of artifacts in the coordination of strategic alliances, enhancing the knowledge about how artifacts present in routines and processes can help to develop the capacity of alliances coordination. The methodology involved multiple case studies in four pharmaceutical companies, because there are many contract strategic alliances in this area as well as Brazilian government incentives. The data about alliances were collected through interviews with managers responsible for their areas in their companies, hierarchy levels 2 or 3. The data were analyzed by beans of category thematic analysis, through cross checking predefined categories. The main categories and the cases were cross checked, resulting in non-defined propositions. It could be concluded that the artifacts contribute in many ways with coordination activities, allowing to organize and synthetize part of the activities present in the processes and routines of coordination, acting as a guide for the execution of the activities. The theoretical contribution of this work is in the way artifacts help in the relationship between the mechanisms, people, processes and structures, helping in the relationship among these three mechanisms, to understand how routines cope with artifacts, and how the predefined actions should be planned, organized, made and controlled. In other words, how they can me managed by managers. The executive point of view is that managers should seek for the most adequate artifacts for developing and controlling the alliances, analyzing the processes and routines for a better understanding of which artifacts could be used. / As alianças estratégicas contratuais são estabelecidas entre empresas parceiras, com o objetivo de obter recursos e capacidades complementares. Gerenciar essa capacidade de relacionamento com parceiros tem sido objeto de estudo de diversos pesquisadores, pois alinhar os objetivos propostos entre os parceiros é um dos desafios para se obter sucesso nas alianças e muitas delas falham neste processo de gerenciamento. Desse modo, neste estudo, objetivou-se a determinar o papel dos artefatos na coordenação das alianças estratégicas, aumentando o entendimento sobre como os artefatos presentes nas rotinas e processos, podem auxiliar no aprimoramento da capacidade de coordenação das alianças. A metodologia envolveu estudos de casos múltiplos em quatro empresas do setor farmacêutico, pois, nesse setor, há grande presença de alianças estratégicas contratuais e incentivo do governo brasileiro para expansão deste setor. Os dados sobre as alianças foram coletados via entrevistas com gestores responsáveis por sua gestão em suas organizações, de níveis hierárquicos 2 ou 3. Os dados foram analisados via análise temática categorial a partir do cruzamento de categorias definidas a priori. As principais categorias e os casos foram cruzados gerando proposições não definitivas. Conclui-se que os artefatos contribuem de diversas formas com as atividades de coordenação, permitindo organizar e sintetizar parte das atividades presentes nos processos e rotinas de coordenação, atuando como um direcionador para a execução das atividades. A contribuição teórica do trabalho está no detalhamento de como os artefatos auxiliam na relação entre os mecanismos, pessoas, processos e estruturas, auxiliando na interelação entre estes três mecanismos, no entendimento de como as rotinas operam com os artefatos, e como as ações que devem ocorrer são planejadas, organizadas, realizadas e controladas, ou seja, administradas pelos gestores. A implicação do ponto de vista da prática executiva é que os gestores devem buscar a disponibilização dos artefatos mais adequados para o desenvolvimento e controle das alianças, analisando os processos e rotinas atuais para um melhor entendimento de quais artefatos poderiam ser utilizados.

Objetivo: Avaliação da influência de artefatos metálicos nas imagens de tomografia computadorizada de feixe cônico (TCFC), causados por implantes dentários, nas estruturas periodontais dos dentes adjacentes a esse implante. Materiais e Métodos: 23 pacientes foram submetidos ao exame de TCFC antes e após a colocação do implante dentário. Foram realizadas medidas da espessura das corticais vestibulares (CV) por um observador calibrado (ICC=0,95), nos cortes parassagitais de imagens previamente obtidas. Foi calculada a frequência de graus de influência do artefato metálico causado pelo implante (leve, moderado e severo) para distância horizontal ao implante, espessura da CV, e distância vertical em relação à crista óssea vestibular (COV). Resultados: excluídos 5 pacientes, em 18 selecionados, examinou-se 24 implantes unitários na região posterior de mandíbula, sendo 24 dentes teste mesiais (DTM) e 17 dentes teste distais (DTD) a esses implantes. Houve associação entre distância vertical da COV e impossibilidade de se mensurar a espessura da CV para o DTM e DTD (p<0,05 para ambos). Não houve associação entre espessura da cortical vestibular e distância horizontal para a severidade de influência de artefatos (p>0,05 para ambos). Houve associação entre distância horizontal e nível de influência de artefatos em quaisquer estruturas periodontais adjacentes ao implante, para DTM e DTD somados (p<0,05). Conclusão: Os artefatos metálicos causados por implantes dentários podem influenciar a interpretação da imagem de TCFC em sítios periodontais adjacentes, e o grau de influência depende da distância horizontal do implante dentário a quaisquer estruturas periodontais, e quanto mais próximo da COV, maior influência do artefato na identificação e mensuração de estruturas na CV. / Objective: The objective of this study was to evaluate the influence of metallic artifacts in CBCT (Cone beam computed tomography) images, caused by dental titanium implants, at adjacent periodontal structures. Materials and Methods: 23 patients were submitted a CBCT examination before and after the implant placement. Thickness Measurements of buccal cortical were performed by a calibrated observer (ICC=0.95), at parassagital cross-sections of previously obtained images. The frequency of influence level (mild, moderate, severe) of the artifact was calculated for horizontal distance of the implant, buccal cortical thickness and vertical distance of the buccal alveolar crest. Results: 5 patients were excluded, and 18 selected, 24 unitary implants cases at posterior mandible were examined, 24 mesial test teeth (MTT) and 17 Distal test teeth (DTT) from the implants. There was an association between the vertical distance of the buccal alveolar crest and the impossibility to measure the thickness of buccal cortical for MTT and DTT (p<0.05 for both). There was no association between the thickness of buccal cortical and horizontal distance for the artifacts level of influence (p>0.05 for both). There was association between horizontal distance and the level of the artifact influence at any periodontal structure, for the sum of MTT and DTT (p<0.05). Conclusion: the metallic artifacts caused by dental implants can influence the CBCT image interpretation at periodontal adjacent sites, and the level of the influence depends on the horizontal distance of the dental implant at any periodontal structures, and the vertical distance from the buccal alveolar crest.

The purpose of this study was to examine the experience of organizational culture among salespeople at a specific workplace. The purpose was also to investigate what motivates these salespeople in their work and the impact culture has on their motivation. We have used a qualitative research method to collect the empirical material. With the help of seven interviews, including six salespeople from one of Sweden’s biggest electronic retailer and also one information interview with a sales consultant, we attempted to find the answer to how they perceive the organizational culture and how it affects their work motivation.  The following questions are used to fulfill this purpose:   How do the salespeople experience the organizational culture?   What motivates the salespeople in their daily work?   What effects does the organizational culture have on the salespersons motivation?  As analytical tools we have used are the concept of organizational culture, Schein's description of the three components of culture and Herzberg Motivation-Hygiene theory.  The results of the study indicate that the salespeople experience a positive organizational culture and that this culture promotes fellowship and unity between colleagues, which in turn contributes to an enhanced motivation. Our study also shows that there are other factors contributing to the salespeople’s motivation such as conscious efforts of the organization and the factors that are built in into their daily work. A strong contest culture is also shown in the organization, the colleagues compete amongst each other to become the best salesperson. / Syftet med denna studie var att undersöka hur försäljarna inom en specifik butikskedja upplever organisationskulturen på sin arbetsplats. Syftet var även att undersöka vad som motiverar försäljarna i deras dagliga arbete samt vilken betydelse organisationskulturen har på försäljarnas motivation.  Vi har använt oss av en kvalitativ undersökningsmetod för att samla in det empiriska materialet. Vi har tagit hjälp av sju intervjupersoner varav sex försäljare i en av Sveriges största elektronikkedjor och en informant som informationskälla till försäljaryrket. Med hjälp av dessa intervjupersoner har vi försökt få svar på hur de upplever organisationskulturen och vad i denna organisationskultur som påverkar deras motivation. Följande frågeställningar används för att uppfylla detta syfte:   Hur upplever försäljarna organisationskulturen?   Vad motiverar försäljarna i deras dagliga arbete?   Vilken betydelse har organisationskulturen på försäljarnas motivation?  Som analysverktyg har vi använt oss av begreppet organisationskultur, Scheins förklaring av organisationskulturens tre olika beståndsdelar samt Herzbergs Motivation-Hygien theory.  Resultatet av undersökningen påvisar att försäljarna upplever organisationskulturen positivt och att denna organisationskultur främjar gemenskapen och samhörigheten mellan kollegorna, vilket i sin tur bidrar till en ökad motivation bland försäljarna. Vår studie visar även att det finns ytterligare faktorer som bidrar till försäljarnas motivation, såsom medvetna insatser från ledningen och faktorer som är invävda i det dagliga arbetet. Även en stark tävlingskultur påvisas i organisationen, där försäljarna tävlar sinsemellan för att bli den bästa säljaren.

Studiens syfte är att skapa en ökad förståelse om hur svenska förskolebarn i åldrarna fyra och fem år interagerar med och uppfattar de olika artefakterna på sin utegård. Med artefakter menas de fysiska redskap som finns på förskolans utegård. Vi har valt att inrikta oss på om barnen leker enskilt eller tillsammans med andra, om de leker utifrån given funktion eller skapad funktion samt hur de ser på artefakter med hänsyn till estetiska omdömen. Vi har använt oss av metoden the Mosaic approach som lyfter fram barns perspektiv. I vår studie har barn fotograferat utegården. Tio barn intervjuades om utegården där barnens fotografier användes för att samtala om och barnen fick sedan guida oss runt på utegården. I resultatet visade det sig att när barnen samtalade om bilderna kom de fram till många olika användningsområden och åsikter kring artefakterna. Under guidningar fick vi se hur fyra barn interagerade med artefakterna och vi fick även en omfattande bild av utegården. Det visade sig att barnen använde sand ihop med artefakterna, vilket kan bero på att sand är lättillgängligt och enkelt att förflytta. Det visade sig även att barn tänker på sin säkerhet eftersom barnen visade en oro att ramla ner från artefakter som var högt placerade. Vår slutsats är att utegården erbjuder enskildhet och lek tillsammans med andra samt att barnen använder givna och skapade funktioner tillsammans med artefakterna. Studiens resultat visar att artefakterna skapar en trivsam utegård, vilket visar sig när barnen gärna samtalar om och visar de olika artefakterna. / The study's purpose is to create a better understanding of how Swedish preschool children aged four to five years interact with and perceive the various artifacts on their patio. With artifacts means the physical tools that are on the preschool’s patio. We have chosen to focus on if the children play alone or with others, if they play by the given function or created function, and how they see the artifacts considering aesthetic judgments. We have used the method of the Mosaic approach that emphasizes the child's perspective. In our study have the children photographed the patio. Ten children were interviewed about the patio where the children's photographs were used to discuss. Four children guided us around the patio. The results showed that when the children talked about the pictures they came up with many different uses and opinions about the artifacts. During guided tours, we saw how four children interacted with the artifacts and we even got a comprehensive image of the patio. It turned out that the children used the sand together with the artifacts, which may be due to the sand is easily accessible and easy to move. It was also found that children think about their safety because the children showed a concern of falling from the artifacts that were highly placed. Our conclusion is that the patio offers privacy and play together with other children, and to use the given and created functions together with the artifacts. The results of the study show that the artifacts create a pleasant patio, which appears when the children gladly talk about and show the different artifacts.

ABSTRACT This text process a design pedagogical research executed in Arvidsjaur during the fall of 2011. The formulation of questions that this study circles around regards how combining design and narration can be used in the development of design pedagogy. Also scrutinized, how did the formulation of this research affect the outcome and what means, in addition their attendance, did the people who partook contribute with?    The purpose is to find a pedagogic angle that moves focus away from the finished product and onto other aspects of the design process. To clarify, by investigating how narration adapts as a tool during a design process this research seek to enlighten ways that we comprehend, and make use of, our surroundings while working towards a common - designed - goal. What comes about when gathering a group of people and asking them to represent Arvidsjaur by designing a cup? The material used emanates from observations, narratives, images and finished artifacts – all deriving from a set of workshops held in the city of Arvidsjaur. To partake in the workshops was voluntary and the invite began with the question/statement: Design and narration? An ethnographically inspired method preceded the structure of the study and hence made it impossible to foreordain what would occur before arriving in Arvidsjaur. By placing the gathered material and observations along with a set of selected theories, such as sociocultural learning and social constructionism, I wish to enlighten and point out qualities, along with weaknesses, that this study occupies.  Beyond a written contribution, and the work on the field, the research resulted in a number of designed cups. These cups were photographed, processed, and depicted in three different ways – as posters and as a series of photographs. These images were on display during an exhibition at Konstfack in December 2011. My contribution to the exhibition was meant as a continuation on questions regarding design and narration. What happens e.g. with an item when it is displayed in this matter? When moved from one context to another? It is thus a way to stress the importance of questioning and challenge the way we apprehend our surroundings and what we chose to enlighten or leave out – a comment on a stirring development. I did not wish to explain to the viewer what the cups narrate; they were made to reveal something on their own. How they ultimately are received becomes yet another way of pointing out that how we experience something is dependent on a variety of circumstances.

Western Anatolia witnessed a crucial and eventful period between the end of the 13th and the middle of the 15th centuries. The region stood in a critical position giving way to trade between East and West, located at the junction of the sea and land routes. This following study concentrates on a crucial aspect of Western Anatolia within these circumstances on the rise, through the 14th and 16th centuries. That is to say, this thesis focuses on the establishment and remodeling of the urban centers in Western Anatolia between the 14th and 16th centuries. In addition, it proposes an in depth analysis of one of these centers, namely Tire to further substantiate its theses on the making of these centers. The main argumentation of the dissertation is twofold. First, it asserts the influence of the socio-economic backgrounds of these urban centers, particularly the role of trade activities, trade relations, trade road and urban network in the making of these towns. Second, it asserts the influence of architectural constituents of urban form in the formation and transformation of these towns. Namely, it argues the role of particular architectural types, monuments that act as urban artifacts in urban development, the most significant of which are building groups in the form of k&uuml / lliyes or zaviyes. Accordingly, the thesis maintains that both trade, trade roads and urban network, related with the socio-economic backgrounds of the urban centers, and particular urban artifacts, that are the components of urban form, affect the making towns as physical entities. It claims that all these factors and the town at their intersection, are in a continuous intercourse and they steadily transform each other. Hence, the thesis endeavors to highlight and corroborate the interrelation of trade roads, urban form, and components of urban form, in regional, urban, and in architectural scale. In so doing, first it studies each of the themes separately within the general framework of Western Anatolian urban centers and next associates them particularly through the in depth analysis of Tire. In these lines, this thesis is an effort to interconnect and integrate the varied scholarly disciplines of social, cultural, economic history, urban geography and particularly architectural history through the explorations on urban space in general. It is also an undertaking to reveal the development and transformation of the urban space concentrating particularly on medieval Western Anatolia.

Människor har olika förutsättningar för att hitta i sin köksmiljö beroende på vilket hälsotillstånd som ligger till grund för den enskilde individen. Det finns personer som har ett försämrat arbetsminne på grund av att de fått diagnosen lindrig Alzheimers sjukdom. Idag ger många köksluckor ingen information om innehållet, och i varje enskild individs kök finns det olika objekt beroende på vad som används. Denna studie handlar om att hitta olika former av åtgärder i köksmiljöer för att lättare kunna hitta, det finns en förhoppning av att problemen med att inte hitta kan minska. Att använda datainsamlingstekniker som litteratur, intervjuer, workshop och fokusgrupp ska det gå att få reda på vilka åtgärder som kan fungera. Resultaten visar på att det finns problem, och dessa är tänkt att lösa med olika åtgärdsförslag. De förslag som framkommit som kognitiva stöd är bland annat, öppna planlösningar, individuella bilder och transparanta luckor.

Denna studie ger ökad kunskap om hur en digital artefakt inom sociala medier skulle kunna uppmuntra till äkthet, som en motpol till profilering för att skapa en balans mellan profilering och äkthet. Studien barhandlar området “hur och varför användare presenterar sig och för sig på ett visst vis i sociala medier”. Detta förstås och diskuteras med hjälp av de två ändpunkterna äkthet och profilering. Studien berör även designerns roll i detta sammanhang. Studien undersöker området genom en litteraturstudie, samt en egen kvalitativ studie i form av semistrukturerade gruppintervjuer. Studien visar att intressenterna upplever de att sociala medier utgör en viss press till profilering. Offentliga miljöer visar sig gynna profilering, medans mindre sammanhang gynnar äkthet. Vad gäller kommunikationsformer så gynnas profilering i de kommunikationsformer som kommer så långt ifrån det fysiskt verkliga mötet som möjligt, medans äkthet gynnas i de kommunikationsformer som upplevs komma så nära det fysiskt verkliga mötet som möjligt. Studien föreslår att en digital artefakt inom sociala medier som syftar till att uppmuntra till äkthet bör skapa en trygg miljö, där allt inte alltid är till för alla och där kommunikationsformer som främjar äkthet uppmuntras. / This thesis gives increased knowledge of how a digital artifact in social media might encourage genuineness, as an antithesis to profiling in order to create a balance between profiling and genuineness. The thesis treats the area of “ how and why we present ourselves in a certain way in social media”. This is understood and discussed with the help of two endpoints; profiling and genuinness in social media. The study also discusses the role of the designer in this context. The thesis explores the area through a literature, but also conduct its own study in the form of semi-structured group interviews. The study shows that stakeholders feels pressure to profiling from social media. Public areas seems to benefit profiling, while smaller context favors genuinness. When it comes to the form of communication it seems that profiling is favored from the forms of communication that come as far from the physically real meeting as possible, while the communicatonforms that provide the experiences similar to a physically real meeting is perceived to be the most genuine. The thesis suggests that an digital artefact in social media that aim to encourage genuinness should create a safe environment, where everything is not always for everyone and where the forms of communication that promotes genuinness is encouraged.
