OBJECTIVES: The purpose of this in vitro study is to measure and compare the accuracy of the conventional impression, the intraoral scanner, and the photogrammetry techniques for full-arch implant-supported dental prostheses at the abutment level. METHODS: An edentulous maxillary master model containing 6 implant abutment replicas (RP analog for screw-retained abutment straight from NobelReplace® Multi-unit Abutment Plus Replica) was fabricated. A reference STL of the master model was obtained using a desktop scanner (inEos X5, Dentsply Sirona) with high trueness and precision and served as the control STL. Three impression techniques were performed: the intraoral scanning (IOS) group (TRIOS 3 Battery Cart, 3Shape A/S), the photogrammetry (PTG) group (ICam 4D Generation 3, Imetric), and the conventional (CNV) group. Ten impressions from each group were tested. Scan bodies in each STL file acquired from the different impression techniques were converted to implant abutment replicas using a digital library. Three tests were completed to compare the different registration techniques. A 3D deviation test between the experimental group and the reference was done on an inspection software (IScan4D Dental Version 9.1.104; Imetric) using a “best fit” algorithm to obtain the root mean square values, and on another inspection software (IScan3D Dental Version 9.1.104; Imetric) using spatial similarity transformation. The second test was meant to assess the angular deviations of the implant abutment replicas using a reverse engineering software (Geomagic Control X 2020.1; 3D Systems). The final test for cross-arch distances was done on an inspection software (IScan3D Dental Version 9.1.104; Imetric) which allows to determine the 3-dimensional coordinates for each implant by using the origin point and compare the cross-arch distance deviations as well as deviations at the x-, y-, and z- coordination. Trueness and precision were the two parameters used to define the accuracy of a system. The term "trueness" was used to see how close the measurements from the experimental files of each group were to those of the reference file. The term "precision" was defined as to see how close the measurements of each experimental files were to each other within the same group. The 3D discrepancies were then calculated and the trueness and precision of the three impression techniques were assessed and compared statistically (α = 0.05). RESULTS: The root mean square of 3D deviation values through the ICP “best-fit” method showed statistically significant differences between the PTG and CNV group (p < .0001), and the PTG and IOS group (p < .0001). The CNV and IOS group did not show statistically significant differences (p = 0.8626) through the “best-fit” method, but significant differences were observed via the “spatial similarity” method (p = 0.0041). Both methods however showed the best results in terms of trueness for the PTG group, followed by the CNV group and least the IOS group. In terms of precision, PTG showed the best results, followed by the IOS group and least the CNV group. The angular deviation test using the “best-fit” alignment method showed that the PTG and CNV had no statistically significant difference (p = 0.7955) and were equivalent. However, both showed a statistically significant difference to the IOS group (p < .0001), which had the highest angular deviation. Finally, in terms of cross-arch distances, the photogrammetry group showed optimal results followed by the IOS group and then the CNV group. In general, the shorter the inter-arch distance, the lower the deviation was. A larger deviation was observed on longer inter-arch distances. Considering the deviations on the 3 axes of each implant, the CNV technique had the highest deviation in the X-axis (longitudinal) and the IOS technique showed the highest deviation on the Y-axis (lateral) and Z-axis (vertical). The PTG technique experienced significantly less deviation on the X-axis, Y-axis, and the Z-axis. CONCLUSION: Within the scope of this study, the photogrammetry technique reported the best accuracy in terms of trueness and precision of implant positions for complete-arch implant rehabilitation. Conventional impressions showed better accuracy results than intraoral scanning in the 3D deviations test and global angular deviation test, however the latter exhibited better results in terms of accuracy in terms of cross-arch distances test. / 2023-08-11T00:00:00Z

Tänker du på det första intryck du får av någon du möter i vardagen? Kanske du funderar på hur dem är som person? Efter att ha sett någon för första gången bildas omedelbart ett första intryck och en uppfattning om dennes personlighet. Syftet med vår kvasiexperimentella studie är att undersöka hur bedömningen baserad på första intrycket av en individs personlighets stämmer överens med hur individen uppfattar sig själv. Urvalet bestod av 10 deltagare, sex kvinnor och fyra män. Åldersspannet låg mellan 23 till 55 år (M= 31,6; SD= 12,0). Deltagare har genomfört personlighetstest, fått se bilder av andra deltagare och sedan bedömt hur de uppfattat deras personlighet. Differensmåtten belyste att deltagare tenderade att självskatta högre poäng än vad de blev bedömda inom personlighetsdragen. Bedömningarna och självskattningarna inom några av personlighetsdragen visade en måttlig till stor effektstyrka (d.v.s. samvetsgrannhet, öppenhet, neuroticism). Men i studien förekom ingen signifikant korrelation mellan bedömd och självskattad personlighet. / Do you think about the impression you make of someone you meet in everyday life? Maybe you are thinking about what they are like as a person? Upon meeting someone, an impression of their personality swiftly develops. Our quasi- experimental study aimed to explore if assessment based on the first impression of an individual's personality is consistent with how the individual perceives themself. The sample consisted of 10 participants, six women and four men. Participants' age range was between 23 to 55 years old (M= 31,6; SD= 12,0). Participants underwent personality tests, viewed images of other participants, and then assessed how they perceived their personality. Differential measure showed that participants tended to self-assess higher scores than they were rated within the personality traits. The ratings and self-assessments in some of the personality traits showed a moderate to large effect size (i.e. conscientiousness, openness, neuroticism). However, there was no significant correlation between rated and self-assessed personality in the study.

This netnographic and autoethnographic study examines self-presentation and impression formation through photographs presented on a gay online dating community, Qruiser. The theoretical framework of Goffman’s performance of self and Asch’s formation of impression was developed based on semiotic signifiers and signified. The study was carried out through participant observation of 200 gay daters’ photographs, online interviews, group discussions and narratives of the author’s personal experience. Observation showed that gay daters primarily presented six categories of photographs: self-portrait, daily pictures, travel pictures, sexually explicit pictures, pictures of objects, and black and white pictures. The daters were asked to justify their photographs in self-presentations, and the responses showed that the signs in the photographs could be both intentional and unintentional. Online interviews and group discussion participants suggested that there were distinctions of central and peripheral signifiers in impression formation. Furthermore, participants felt that misunderstanding of impressions resulting from dating photographs was unimportant, due to the compensation of textual presentation and messages.

The primary goal of this study is to explore the impact of dominant cultural patterns associated with the contemporary workplace on organizational members' experience of time. First, in order to investigate such potential relationships, three temporal factors---varying levels of synchronicity, temporal compression, and temporal expansion---are identified as contemporary dominant cultural patterns. Next, these dominant cultural patterns are isolated to reflect three growing communication practices: multicommunicating, virtual work practices, and primary work location. With a review of the literature, these communication practices are tested with seven dimensions of time (present time perspective, urgency, pace, flexibility, punctuality, separation, and linearity). A secondary goal is to also examine both organizational members' temporal experience and communication practices with the impression management strategy, exemplification. Taken together, each goal and subsequent findings helps to inform our understanding of contemporary communication phenomenon. / text

This thesis is concerned with how entrepreneurs’ performance - the act of impression (Goffman, 1959a), is accomplished through emotion management - the work that an individual does to manage and display situation-appropriate feelings (Hochschild, 1983). There is literature that suggests that understanding entrepreneurs’ emotion management is needed (Goss, 2008; Hampson & Junor, 2005) with Goss (2008) maintaining that entrepreneurs’ management of emotion is integral to their activities. This thesis provides the specific consideration that has been lacking. Empirically, drawing on data obtained from entrepreneur interviews, this study extends Hochschild’s (1983) list of occupations that conduct emotion management to the field of entrepreneurship. Theoretically, Hochschild’s (1983) theory of emotion management has been reconceptualised to become more interactionally sensitive. Influenced by symbolic interactionism (Blumer, 1969) with experiences, interpretations of meaning and actions drawn on to show how performance and emotion management emerge in interaction. Emotion management is conceived of as a negotiation where both ‘normative’ pressures such as the two sets of entrepreneurship feeling rules that have been identified – feeling of engagement and feeling of detachment, and interpretive conceptualisation, are taken into account in the development of a shared scheme of understanding. Goffman’s (1959a) ideas around the presentation of self have been drawn on in rendering visible entrepreneurs’ performance as embodied, relational co-operative, and professional and appropriate. Entrepreneurs are negotiators conceiving of their performance and emotion management as resourceful, negotiated, self-interpretive work. This negotiated work is a process of ‘fluid equilibrium’, that is, a dynamic continuous process of negotiation where entrepreneurs’ legitimation is produced and maintained. Entrepreneurs negotiate power dimensions drawing on strategies such as bounded disclosure where they manage the information they divulge. However the findings from this study also demonstrate that tensions and complexities can emerge resulting in lapses in performance. These are explained through issues of ambivalence towards emotion management, ambiguity over social boundaries and inadequacy in managing information flow.

Detta examensarbete har behandlat rekryteringsprocessen med fokus på intervjun. Arbetet har avgränsats till att studera icke-verbal kommunikation och mentala genvägar som kan förekomma i en arbetsintervju. Semi-strukturerade intervjuer genomfördes med sju intervjupersoner. Resultatet analyserades med tematisk analys. Forskning om rekryteringsprocessen, intervjumetodik, icke-verbal kommunikation och mentala genvägar användes som bakgrund vid analysen. Resultatet visar att icke-verbal kommunikation påverkar hur en kandidat uppfattas och att även mentala genvägar kan påverka.

Syftet med denna studie har varit att söka svar på polisaspiranters subjektiva upplevelser av hur deras icke verbala kommunikation fungerat under deras praktikperiod, den så kallade aspiranten, detta i syfte att utveckla undervisningen inom ämnet. Studien har genomförts med en kvalitativ ansats, där semi-strukturerade intervjuer använts för att söka svar på dessa frågor. Studien visade att aspiranterna under såväl skoltid som under sin aspirant upplevde att de fått lite eller ingen feedback på sin icke-verbala kommunikation av kollegor och lärare. Lärandet har istället i hög grad skett genom att observera mer erfarna kollegor som aspiranterna själva upplevt varit kompetenta kommunikatörer ur ett icke-verbalt perspektiv. Studien har vidare visat att liten vikt fästs vid icke-verbal kommunikation i det studiematerial som finns tillgängligt inom svensk polis, något som försvårat aspiranternas möjlighet att problematisera och reflektera kring icke-verbal kommunikation, samt att mycket av den kunskap som finns inom ämnet är implicit och finns på individnivå. Ytterligare en faktor som försvårat aspiranternas utveckling inom ämnet har varit avsaknaden av en gemensam nomenklatur inom svensk polis vad gäller icke-verbal kommunikation. Samtliga aspiranter som intervjuats framhävde den egna förmågan att med icke-verbal kommunikation visa empati och knyta kontakter som en styrka, medan merparten av aspiranterna upplevde att förmågan att visa hög status eller dominans som en brist. Sammanfattningsvis kan sägas att trots att forskningen visar att polisyrket ställer stora krav på individen att vara en flexibel och kompetent kommunikatör och att det icke-verbala står för en stor del av vår kommunikation, så förefaller det finnas ett behov av att utveckla utbildningen vad den icke-verbala kommunikationen inom svensk polis.

The thesis is an overview of current approaches to the issue of listeners attitudes towards speakers based on the characteristics of their speech, with regard to the methodology and to the types of monitored attributes of speech. The existing research results and methodological approaches are evaluated with specific attention given to speech defects in Czech language. A review of survey data was conducted that addressed the attitudes of Czech listeners towards Czech speakers with speech defects, specifically with sigmatism. For this purpose, records of 8 speakers with sigmatism selected from the Prague Phonetic Corpus were used. These records were modified in a manner that corresponds to the methods of Matched guise technique. Afterwards a perception test and a questionnaire were compiled in order to investigate the real attitudes of the Czech listeners toward selected Czech speakers, respectively their speech impairments. The test was presented to homogeneous group of 42 respondents. The results suggest a significant link between sigmatism and the negative attitudes of listeners towards speakers, especially the perception of their social status. The overall result of this thesis is the description of the target area (see the title of the paper) the has led to the formulation of hypotheses for...

A pesquisa centra-se no estudo do gerenciamento de impressões no mercado empresarial brasileiro, analisando a relação entre gestores e investidores da empresa, com base na teoria da atribuição. A teoria da atribuição explica que a pessoa, em um ambiente de interação com outras, costuma associar fato positivos a si mesmo e evitar os negativos, garantindo que sua imagem não seja arranhada. Para observar o fenômeno o trabalho adaptou a pesquisa de metodológica de Brennan et al (2009), que desenvolveu uma estrutura para identificar indícios de gerenciamento de impressões em narrativas textuais. Como instrumento de pesquisa foi selecionada um estudo de caso da empresa Petrobras, durante o exercício de 2014, analisando dados secundários da organização. A pesquisa é qualitativa e interpretativa, procurando observar o gerenciamento de impressões considerando o contexto de mercado inserido a Petrobras. Os resultados apresentaram indícios de gerenciamento nos documentos analisados corroborando com as explicações apresentadas pela teoria da atribuição. A pesquisa contribui para os estudos da qualidade das informações, ressaltando como o processo de gerenciamento de impressões pode ser realizado / The research focuses on the impression management in the Brazilian business market, analyzing the relationship between managers and investors of the company, based on the attribution theory. The theory of attribution explains that the person, in an environment of interaction with others, usually associates positive fact with himself and avoid negative ones, ensuring that his image is not impaired. To observe the phenomenon the work adapted the methodological research of Brennan et al (2009), who developed a structure to identify indications of impression management in textual narratives. As a research tool, a case study of the Petrobras company was selected, during the 2014 fiscal year, analyzing secondary data of the organization. The research is qualitative and interpretive, seeking to observe the management of impressions considering the market context inserted in Petrobras. The results presented management evidence in the documents analyzed, corroborating the explanations presented by the attribution theory. The research contributes to the studies of information quality, highlighting how the process of managing impressions can be realized
