Confeccionou-se uma base metálica contendo dois implantes hexágono externo e a partir desta obteve-se uma barra metálica soldada a laser. Para os procedimentos de moldagem foram confeccionadas 15 moldeiras individuais padronizadas em resina acrílica autopolimerizável. Os grupos foram divididos em 6, sendo que cada grupo foi composto por 5 corpos-de-prova: Grupo A - transferentes unidos com fio dental e resina acrílica (Duralay); Grupo B - transferentes unidos com resina acrílica (Duralay) em bastão pré-polimerizado; Grupo C - transferentes unidos com fio dental, resina acrílica (Duralay), seccionados depois da presa e soldados; Grupo D - transferentes unidos com fio dental e resina bis-acrílica (Structur 2SC); Grupo E - transferentes unidos com resina bis-acrílica (Structur 2SC) em bastão prépolimerizado; Grupo F- transferentes unidos com fio dental, resina bis-acrílica (Structur 2SC), seccionados depois da presa e soldados. O material de moldagem utilizado para todos os grupos foi a silicona de adição Adsil e para o vazamento dos modelos utilizou-se o gesso especial tipo IV. Para mensuração vertical das alterações dimensionais a barra metálica foi parafusada na matriz e em cada um dos corpos-de-prova, com torquímetro manual sob torque de 20 Ncm. Os valores foram obtidos com auxílio do programa de captura digital de imagens Axio Vision Rel 4.8 e câmera digital AxioCam acoplada ao Microscópio Ótico Discovery V20 (Zeiss), com aumento de 100X. A distância entre a superfície externa do análogo de implante e a borda inferior da barra metálica (gap) foi medida na região mediana da imagem em foco. A fim de identificar diferenças entre resinas e métodos foi utilizada a Análise da Variância de duas vias (ANOVA). Estatisticamente não houve diferença entre as resinas (p=0,87) e não houve diferença entre os métodos (p=0,577). O Grupo F obteve a menor média total de gap. Quando observadas as interações entre resinas e métodos de união, o Teste “t” de Student identificou que houve diferença estatisticamente significante entre os Grupos B e E (p= 0,059) sendo que, o Grupo B obteve melhor resultado. Foi considerado significante p≤0,05. / This in vitro study examined by a comparative way impression splinting two materials and three methods for transfer copings in prothesis over implants in order to optimize this phase of impression and get better final adaptation. Performed to a metal base containing two hexagon external implants and gave a metal base welded by laser. To make the impression, was made 15 individually trays that were prepared in standard acrylic resin. The groups were divided in 6, each group was composed of 5 samples. Group A - transfer copings splinted with dental floss and acrylic resin (Duralay); Group B - transfer copings splinted with pre-polymerized acrylic resin (Duralay) bars; Group C - transfer copings splinted with dental floss, acrylic resin (Duralay), sectioned after setting and welded; Group D - transfer copings splinted with dental floss and bis-acrylic resin (Structur 2 SC); Group E - transfer copings splinted with pre-polymerized bis-acrylic resin (Structur 2SC) bars; Group F - transfer copings splinted with dental floss, bis-acrylic resin (Structur 2SC), sectioned after setting and welded. The impression material used for all groups was the addition silicone Adsil and the casting of the models used the special plaster type IV. To measure the dimensional changes of the vertical metal bar was bolted in the matrix and in each of the samples, with manual torque wrenches under torque of 20 Ncm. The values were obtained with the aid of program capture digital images Axio Vision Rel 4.8 and AxioCam digital camera coupled to optical Discovery V20 microscope (Zeiss) with 100X. The distance between the outer surface of the implant analog and the lower edge of the metal bar (gap) was measured at middle region of the image into focus. In order to identify differences between resins and methods we used Analysis of Variance two-way (ANOVA). There was no difference between the resins (p = 0.87) and no difference between the methods (p = 0.577). Group F showed the lowest average total gap. When observing the interactions between resins and splint methods, the Test "t" Student identified that the difference was statistically significant between Groups B and E (p = 0.059) and the Group B had a better result. Was considered significant if p ≤ 0.05.

[pt] O crescimento da atividade empreendedora no Brasil, associado à expansão das incubadoras de empresas, coloca em destaque a importância de se identificar os principais fatores estratégicos relacionados ao sucesso deste tipo de negócio. O sucesso de uma empresa não depende somente de bons produtos e serviços. Uma boa estratégia é fundamental, mas para isso é preciso saber como aplicá-la, inovando sempre. O único modo do empreendedor sobreviver, dada a concorrência que se forma, é construir competências únicas que diferenciem a organização emergente dos seus competidores, uma vez que conjuntos únicos de recursos são primordiais para a geração de vantagem competitiva criadora de valor. Este pesquisa tem como objetivo identificar quais são as estratégias mais adequadas ao contexto atual no caso de empresas empreendedoras, considerando seus recursos, inclusive competências, por meio de um levantamento de percepções do tipo Survey, complementado por depoimentos em entrevistas pessoais. A interpretação e a análise dos dados foram realizadas com base no referencial teórico, fundamentado em revisão de literatura relacionada à área em estudo, com auxílio do modelo genérico integrativo de Macedo-Soares (2001b). O presente estudo teve como foco as empresas empreendedoras pertencentes à incubadoras de três grandes universidades do Rio de Janeiro. (PUC, UFRJ e UERJ), abrindo caminho para que esta pesquisa possa ser realizada em âmbito nacional. Os resultados da pesquisa evidenciaram uma adequação entre os objetivos estratégicos explicitados pelas empresas, permitindo valorizar suas forças, reduzindo as fraquezas destas organizações, de modo a potencializar oportunidades e minimizar ameaças de seus ambientes competitivos. Como recomendação resultante da pesquisa, sugere-se a realização de novos trabalhos enfocando empresas empreendedoras oriundas de incubadoras de outros estados que não o Rio de Janeiro, ora pesquisado. / [en] The growth of the entrepreneurship activity in Brazil, together with the expansion of the business incubators, gives evidence to the importance of identifying the main strategic factors related to the success of this kind of business. The success of an entrepreneur is not only dependable on its good products and services. A good strategy is of fundamental importance; however, it is necessary to know how to apply it, always innovating. The only way for an entrepreneur to survive, under the competition that is formed, is to build unique abilities to make the emerging organization different from its competitors, once unique groups of resources are essential to the generation of a competitive advantage in the creation of value. This research has the objective of identifying the most adequate strategies within the present context in the case of entrepreneurship business, considering their resources, including competence, through the raising of perceptions of the Survey type, complemented by the testimonies of personal interviews. The interpretation and analysis of the data have been achieved based on the reference theory, and evidenced by the revision of pertinent literature in the area under study, with the help of the integrative generic model of Macedo -Soares (2001 b). The present study is focused on entrepreneurship business belonging to the incubators of three large universities of Rio de Janeiro (PUC, UFRJ and UERJ), setting the way for this research to be undertaken nation wide. The results of the research have evidenced an adequacy between the strategic objectives expressed by the enterprises, allowing the valuation of their forces, reducing the weaknesses of these organizations, in order to potentiate opportunities and to minimize the threats of their competitive environments. As a recommendation resulting from this research, it is suggested that new researches be undertaken, with a focus on entrepreneurship business originated from incubators, in states other than Rio de Janeiro, herein searched.

This research aims at finding a foundation for assessment of capabilities and applying the concept in a human resource selection. The research identifies a common ground for assessing individuals’ applied capability in a given job based on literature review of various disciplines in engineering, human sciences and economics. A set of criteria is found to be common and appropriate to be used as the basis of this assessment. Applied Capability is then described in this research as the impact of the person in fulfilling job requirements and also their level of usage from their resources with regards to the identified criteria. In other words how their available resources (abilities, skills, value sets, personal attributes and previous performance records) can be used in completing a job. Translation of the person’s resources and task requirements using the proposed criteria is done through a novel algorithm and two prevalent statistical inference techniques (OLS regression and Fuzzy) are used to estimate quantitative levels of impact and utilisation. A survey on post graduate students is conducted to estimate their applied capabilities in a given job. Moreover, expert academics are surveyed on their views on key applied capability assessment criteria, and how different levels of match between job requirement and person’s resources in those criteria might affect the impact levels. The results from both surveys were mathematically modelled and the predictive ability of the conceptual and mathematical developments were compared and further contrasted with the observed data. The models were tested for robustness using experimental data and the results for both estimation methods in both surveys are close to one another with the regression models being closer to observations. It is believed that this research has provided sound conceptual and mathematical platforms which can satisfactorily predict individuals’ applied capability in a given job. This research has contributed to the current knowledge and practice by a) providing a comparison of capability definitions and uses in different disciplines, b) defining criteria for applied capability assessment, c) developing an algorithm to capture applied capabilities, d) quantification of an existing parallel model and finally e) estimating impact and utilisation indices using mathematical methods.

Litteratur visar på att bysthållare (BH) är ett mycket komplext plagg och endast småjusteringar kan förändra passformen. I denna studie har BH konstruerats med syfte attundersöka vad olika avskärningar över kupan gör med passformen. På modeföretaget därstudien utförts fanns det ett önskemål om bra BH-grunder som underlag för att undvika attleverantören gör konstruktionerna, då måttlista och skiss inte anses som tillräckligt braunderlag att skicka. Genom att själva göra konstruktionerna anser sig företaget få merkontroll över BH:ns passform. Konstruktionerna i denna studie har utvecklats i CADprogramvaranModaris. Detta följt av uppsömnad och avprovning, där BH:arna testas påolika provmodeller med mått motsvarande företagets målgrupp. Under avprovningarna haravprovningsprotokoll förts, där frågor relaterade till litteraturen ställs till de medverkande.Det visar sig att passformen förändras när avskärningen gör det. Detta på grund av attfördelningen av vidden ändras, vilket innebär att kupan får en ny form. För att undvikapassformsproblem på företag kan en idé vara att utveckla ett flertal olika grundkonstruktionermed olika avskärningar, så att endast mindre justeringar krävs, och färre justeringar behövsgöras från grunden. / Literature shows that bras are a very complex piece of clothing and only small adjustmentscan change the fit. In this study, bras has been constructed with the purpose to examine whatdifferent cuts on the bras cup make with the fit. The fashion brand where this study has beenperformed, wanted a basic pattern for bras, since communication with vendors using onlysketches and measurement lists was not enough to get a good result. The patterns in thisstudy have been developed in CAD software Modaris. This followed by sewing and fittingsessions on fitting models with body measurement corresponding to the brands target group.During the fittings, a protocol related to literature is written. After analysing the fit of thebras, it came to show that shape is changed even though the width of the cup is the same.This is because the width is divided differently which gives the cup a new shape. To avoidfitting problems it could be a good idea that companies have more than one basic pattern forbras with different cuts to base their models on, to decrease the proportion of major fittingchanges.

Enterprise resource planning (ERP) system which first emerged in the early 90’s, have become so popular today that almost every large business corporation uses one. Recent years have seen increased spending on this software application package, but sadly not all organizations which invest in ERP systems have gotten back their money’s worth. There have been many instances of unsuccessful ERP implementation attempts and in some cases total failure. Researchers and scholars have long since studied these systems in a bid to provide explanations for the complexity and failure of implementation attempts. This has led to the establishment of critical success factors (CSF), which slightly vary with different authors but have some strong common points. Prominent among these CSF’s is alignment between business processes and ERP built-in processes. This project therefore focuses on alignment issues that arise between the software package and the organization’s business processes during ERP implementation efforts. The main purpose of the work is to establish a set of ‘best practices’ that must be considered or executed in order to secure a good alignment between the system and software package. In order to achieve the main goal of this work, a case study approach has been used. The case in question is a small manufacturing firm in Vetlanda called T-Emballage, which uses an ERP system Jeeves. Mainly using scientific research techniques which comprise a deductive approach and a mixed mode data collection method, some valuable conclusions are drawn from the analysed data. The critical points that are worth considering during ERP implementation, when trying to achieve alignment, arrived at in this study include: carrying out a proper gap analysis, top management leading and following up, choosing software according to needs, simplicity, flexibility, communication and liability of data. This project further investigates the advantages and disadvantages of adapting or altering the software package to fit the organization’s business processes and vice versa. Finally, the work also tries to assess the alignment maturity level that has been attained in the organization by applying the Luftman’s alignment maturity model.

Historically, companies disseminated financial information via the press release. The ability to disseminate information now exists on multiple "new media" channels beyond just the press release, with each channel reaching a different audience. With the different channels of communication come different connotations and associations that people have about the channels, which may affect the interpretation of the message, thereby altering management's ability to effectively communicate with stakeholders. I investigate whether retail investors' processing of financial information disclosures is dependent upon the fit between the channel and the type of information sent on the channel. Using the Elaboration Likelihood Model, I experimentally test how good and bad financial information posted on a social media channel, Twitter, compares to a more traditional channel, a company investor relations page where financial information is traditionally posted. I find that Twitter is associated with investors processing financial information unconsciously on the peripheral route while conscious or central route processing is associated with information coming from the company's investor relations page. Additionally, I find that investors have lower perceptions of management credibility after viewing financial disclosures on a company's Twitter feed than after viewing the same disclosures on the company's investor relations page.

The recent global economic downturn has stimulated a growing interest among scholars in how employees interpret and respond to the circumstance of being overqualified. However, the overqualification literature has been hindered by uncertainty regarding the extent to which employees’ perceptions of being overqualified are based in reality. The present study sought to address this concern by proposing and testing a theoretical model of objective overqualification, perceived overqualification, job satisfaction, and well-being using a cross-sectional sample of full-time employees who had recently graduated from college. Additionally, the present study investigated cognitive ability, achievement striving, and trait negative affectivity as potential moderators of several relationships delineated in the proposed model. Results indicated that the data were consistent with the proposed model, which argues that objective overqualification predicts employees’ perceptions of being overqualified, which creates feelings of relative deprivation and ultimately manifests in poorer job satisfaction and reduced well-being. Importantly, however, the pattern of relationships among study variables suggested that strain outcomes were mostly driven by perceived overqualification. Furthermore, employees’ perceptions of being overqualified appeared to be influenced considerably by unmeasured factors besides objective overqualification, potentially including dissatisfaction with other aspects of the job. There was no support for the hypothesized individual moderators. Overall, the study highlights the importance of taking a more nuanced approach to studying overqualification phenomena and cautions against the assumption that being objectively overqualified is a necessarily undesirable circumstance for individuals and their employers.

I denna studie har en modell tagits fram för att utvärdera informationssystem med kvalitativa metoder. Denna modell har utvecklats med task technology fit theory (TTF) som ramverk, som tidigare använts främst i kvantitativa studier för att undersöka till vilken grad funktioner matchar med användares uppgifter i ett informationssystem. Modellen som utvecklats i studien har istället syftet att se vilken data som kan genereras för att skapa djupare förståelse till faktorer som ligger bakom när matchningen är dålig. Modellen har testats i en fallstudie med företaget Visma Spcs där deras webbaserade fakturerings- och bokföringssystem eEkonomi har utvärderats. Detta gjordes genom en datainsamling i form av semi-strukturerade intervjuer på användare av systemet. Resultaten visar att modellen kan generera data för att skapa djupare förståelse genom att visa hur funktioner matchar dåligt, varför de matchar dåligt, vad den upplevda effekten blir för användarna och hur användarnas behov egentligen ser ut. Datan kan även användas för kartläggning av de uppgifter som utförs i ett informationssystem. Till vidare forskning ges förslaget att kombinera denna modell med kvantitativa metoder, där den kan användas i utforskande syfte före en kvantitativ studie eller i ett förklarande syfte efter en kvantitativ studie.

In a criminal investigation, witnesses may get asked by the police to provide a perpetrator’s description or to generate a composite image of the perpetrator’s face. Due to their elevated vulnerability to victimisation people with a learning disability (LD) may be more likely than other members of the wider community to find themselves in such situations. Research regarding face recognition and description abilities of this group has been to some extent neglected in the eyewitness research literature. Consequently, guidance for practitioners on how to effectively generate facial composite images with LD witnesses is limited. The current research addresses this issue, by investigating basic and applied face recognition and description abilities in individuals with mild learning disabilities (mLD) during a series of experimental studies. Moreover, potential facilitating measures are introduced and assessed. Five studies were conducted during the course of this thesis. In the first study a survey was designed to collect information on currently used composite systems by UK law enforcement agencies and how operators perceive and treat witnesses with LD. The survey findings confirmed the initial assumption that individuals with LD may indeed find themselves in the situation of having to describe a perpetrator’s face to an investigative officer. Furthermore, the results emphasised the lack of guidance available to operators on how to best meet the special needs of this particular witness population. Study 2 investigated basic face recognition and description abilities in people with mLD and revealed that overall they performed at a lower level than the non-LD controls. Despite this finding, mLD individuals as a group performed above chance levels and they displayed variability in performance depending on the introduced measures. iv Studies 3 and 5 investigated these abilities in a more applied setting, namely during the construction of facial composites with contemporary facial composite systems. Study 3 revealed that composites generated with the E-FIT system, a featural system, were considerably poorer than those created by their non-LD counterparts. Studies 4 and 5 attempted to improve mLD individuals’ performance by applying visual prompts and by using a more holistic facial composite system, i.e. EvoFIT. There was little evidence of the former being advantageous for witnesses with mLD, however, EvoFIT significantly enhanced composite construction abilities in the mLD participants. Finally, the practical and theoretical implications of the main findings are discussed.

This study explored the relationship between Chinese national identity and media framing and priming effect by combining the two paradigms, the literature of group identity and the discourses of media cognitive effect. Extending social identity theory (Tajfel, 1981), self-categorization theory (Turner, et al., 1987) and subjective group dynamics theory (Marques, Paez, & Abrams, 1998), the current study drew the distinction between descriptive (cognitive/perceptual) and prescriptive (affective/subjective) fit of the social norms that contributed to social identity. After deliberating the macro concept (the ascribed vs. acquired) of a national identity (Westle, 2014), as well as the social, political, economic and cultural conditions in China, the structure of Chinese national identity (CNI) were delineated by three content-based categories: the meta-structure of the ethnic-cultural (MEC), the flexible ethnic-cultural (FEC), and the civic-institutional (CI) component, with each of which possessed the dichotomy of psychological dimension. The 3×2 matrix of Chinese national identity was hypothesized to have an impact, with structural variation, on evaluative judgments of alternative media frames of stories involving international disputes in China. To maximize internal and external validity, the empirical data had been collected through an online survey experiment with a sample size of 738. The theoretically argued relationship between the CNI, media framing, and the evaluative judgment was in accordance with the results derived from a series structural equation modeling analyses.
