This study examines effective leadership qualities in the world of professional ice-hockey. The study builds on semi-structured interviews where three coaches and two general managers participated. The paper has an inductive approach where a thematic analysis lay the foundation for a theoretical explanation. Results indicate that the leader needs to handle stakeholders in an innovative way, have a dynamic relationship between a transactional and transformational leadership, and finally, the leader's experience and emotional intelligence are two crucial factors in developing a successful and effective leadership. Practical implications for findings in this study are discussed along with recommendations for future research.

Aujourd’hui l’électronique fait partie intégrante de nos vies. En effet, de plus en plus d’objets intègrent de l’électronique permettant de les connecter, on appelle cela l’internet des objets (IoT). Tous ces dispositifs disposent d’une connectivité sans fil, rendant ainsi indispensable l’intégration d’une ou plusieurs antennes. De plus, l’électronique devant s’adapter à des objets de plus en plus petits et flexibles embarquant de plus en plus de capteurs tout en consommant de moins en moins d’énergie, il est intéressant de se pencher sur l’étude de nouveaux matériaux pour la réalisation d’antennes devant s’adapter à ces nouvelles contraintes. Dans ce cadre, nous nous sommes attachés dans ce travail de recherche, à la conception de structures antennaires à base de métaux liquides à température ambiante dans le but de réaliser des antennes conformables de formes complexes associant l’impression 3D, des antennes reconfigurables et des structures rayonnantes ayant la capacité de capteur. Dans ce manuscrit des prototypes d’antenne comportant ces caractéristiques ont été simulés, réalisés et mesurés. / Today, electronic is an integral part of our lives. Indeed, more and more objects integrate electronics to connect each other, this is the Internet of Things (IoT). All of these wireless devices need one or more antennas. Furthermore, It’s useful to develop new materials to realize new antennas that fit with new constraints: smaller and flexible objects, more and more sensors and less and less consuming.In this context, we have focused this research on antenna structures based on metals which are liquid at room temperature to realize conformable antennas of complex shapes combining 3D printing, reconfigurable antennas and radiant structures with the ability to sensor. In this manuscript, antenna prototypes with these characteristics have been simulated, realized and measured.

Isso pode ser viabilizado pelo desenvolvimento de técnicas que diminuam etapas de execução de um determinado tratamento. Pensando nisso, esse trabalho tem por objetivo avaliar a desadaptação marginal de copings em liga de cobalto-cromo (Co-Cr) através da técnica da réplica de silicone (2D) e avaliação por varredura digital (3D), em 24 dentes humanos unirradiculares, com retentores intraradiculares (RIR) em Co-Cr, cimentados com cimento de fosfato de zinco. Divididos em dois grupos, ambos com término marginal em ombro 130º: grupo A obtidos pelo método convencional, com execução de RIR primeiro, para depois coping com retentor já cimentado e grupo B de moldagem única para obtenção de RIR e coping. Os resultados foram submetidos a uma análise do teste t e de variância ANOVA. A técnica da réplica de silicone, demonstrou as seguintes médias de valores marginais: 83,77±51,84μm (grupo A) e 77,09±31,65μm (grupo B) p=0,4477 E a varredura digital, os resultados positivos revelaram que as médias de todas as superfícies encontraram-se acima de 50 μm; e os negativos: revelaram que as médias encontraram-se abaixo de 100 μm. Este estudo concluiu que é possível obter RIR e coping através de moldagem única / Abstract: The optimization of the clinical appointment is a direct benefit to the health of the patient, because prevents it from the contact with possible contaminations and environments that cause stress. This can be possible by the development of techniques that may decrease the execution stages of a treatment. With this in mind, the aims of this study is to investigate the marginal adaptation of Cobalt-Chromium alloy (Co-Cr) copings through silicone replica technique (2D) and digital evaluation (3D) in 24 human single rooted teeth with post-and-core in Co-Cr, cemented with zinc phosphate. Divided in to two groups, both having shoulder 130 degrees as marginal type: group A by the conventional method, impression and cementation of Co-Cr post-and-core first and then impression for the coping and group B single impression for coping and post and core. The results were analyzed by test t and one-way ANOVA. The silicone replica technique showed the following mean marginal values: 83.77 ± 51.84 μm (group A) and 77.09 ± 31, 65 μm (group B) p= 0,4477. The digital protocol, in the positive results revealed that the averages of all surfaces were above 50 μm; and the negatives: revealed that the averages were below 100 μm. This study concluded that it is possible to obtain post-and-core and coping through a single impression technique / Mestre

Footwear and tire impressions are critical evidence commonly found at a crime scene. However, they are often undervalued because they are hard to be captured and documented. Traditional 2D evidence quality photographs do not adequately provide metric depth information, and physical casts destroy the evidence afterward. Therefore, the forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and lab use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high-quality footwear and tire impressions evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera-pixel spatial resolution. This paper presents a high-resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high-quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high-end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high-end commercially available 3D scanner, while having the merits of being 1) more affordable; 2) much easier to operate, and 3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it 1) is non-destructive; 2) collects more evidence detail than casts, especially when an impression is fragile; 3) requires less time and money to collect each piece of evidence, and 4) results in a digital file that can easily be shared with other examiners.<br>

A major concern with using personality tests in the selection process is the prevalence of applicant faking behavior which can influence the rank order of applicants such that fakers are hired at an elevated frequency. This study examined the effects of the detection/consequence warning and a more applicant-friendly warning on faking and perceived procedural justice. I hypothesized that a positive warning (reasoning warning) and a detection/consequence warning would show similar mean personality trait levels compared to honest responses, with all means showing less socially desirable responding than no warning prompt. Results suggested that the detection/consequence warning is more effective at reducing faking behavior in the selection context, and the content of the warning has no impact on perceived procedural justice.

This thesis aims to examine corporate storytelling and provide a more holistic understanding of the communication strategy by exploring the recipients experiences of such type of communication. On a more particular note the study tries to provide an understanding of how corporate storytelling is received by potential consumers and in which ways corporate storytelling can contribute to organisations legitimacy. Hence, the theoretical framework of legitimacy by Max Weber (1922) are used to approach the aim of the study. Other theoretical frameworks applied in this study are those of Erving Goffman (2014) and Walter Fisher (1984), namely management impression and the narrative paradigm. The empirical data on which the result is based upon are gathered through interviews were the informants are asked questions about their experiences of four different commercials in which corporate storytelling are applied in two of them and more traditional marketing communication in the other two. Thus, the study takes a qualitative and comparing approach to the research. Moreover the study finds that corporate storytelling could be seen as a form of management impression as the strategy seems to increase organisations positive conspicuity and contribute to their ability to differentiate themselves. It also finds that the communication produced by corporate storytelling is perceived to be more authentic and coherent as well as clear regarding the ability to provide the story with distinct moral and values. In essence this means that corporate storytelling could be associated with narrative rationality, which is believed to be one major reason to how corporate storytelling affects potential consumers, which in return also answers the question to in which ways the strategy can help organisations to generate legitimacy. Lastly the study finds that an organisation by implementing corporate storytelling in their external communication could generate organisational charisma, which is seen as an important part of organisations quest for legitimacy. It shall also be noted that the study concludes that more research need to be conducted in order make more generalising claims.

Environmental, social, and corporate governance (ESG) related issues has increased in relevance in recent years. To address societal pressures, many firms introduce corporate social responsibility (CSR) committees in their boards. The purpose of this study is to investigate whether CSR committees have an impact on ESG performance in Swedish listed firms. Prior literature has offered inconsistent findings regarding the link between CSR committees and ESG performance, which might be due to the lack of systematic understanding on the topic or the use of varying ESG measurements. This study contributes to the present knowledge by analyzing if CSR committees substantively increase ESG performance, or if it may simply be a symbolic act to enhance legitimacy, meet stakeholder demands, and conform to normative pressures in high stakeholder-oriented countries, such as Sweden. A multiple OLS regression is conducted to analyze a sample of 299 Swedish listed firms on Nasdaq OMX Stockholm for the year 2020. The results indicate a positive and significant relationship between CSR committees and ESG performance, which could be interpreted as CSR committees not being utilized as impression management tools but rather fundamentally contribute to increase the firm’s ESG performance. However, drawing generalizable conclusions is difficult since the study is limited by endogeneity concerns. Nevertheless, these results may have implications for practitioners who consider implementing CSR committees to enhance the firm’s ESG performance.

Internet has become increasingly ubiquitous and with the introduction of Web 2.0 technologies and concepts it has almost become second nature for many Internet users. This study attempts to view the “social life” of this “new” online environment through its current manifestation in the form of the popular social networking site Facebook. It argues that Facebook has become a tool for the management of one's self both online and offline and that people's reflexive relation to their self-identity is made visible through their engagement with this social media. How such a new form of social media incorporates itself into everyday life but also how the media acts as an extension of the reflexive self has been the main focus of this study.

Det har blivit allt viktigare för företag idag att tillgodogöra alla intressenters intressen. Samtidigt ställs det högre krav från myndigheter för att säkerställa att organisationer är hållbara från ett perspektiv av miljö, sociala sammanhang och bolagsstyrning. Detta har medfört att organisationer också lagt allt större vikt vid rapportering om vad som kommit att kallas Corporate Social Responsibility (CSR). Denna typ av rapportering och redovisning syftar till att öka transparens hos bolag för att tydligare belysa påverkan på omgivningen och dess intressenter. Tidigare studier på området har visat att företag utnyttjat detta tillfället för egen vinning genom att påverka bilden av företaget åt ett önskvärt håll, istället för en objektiv redogörelse av verksamheten. Den här studien avser att kvalitativt undersöka hur kommunikationen hos ett företag i en koldioxidintensiv bransch kan se ut. En tematisk analys har utförts på uttalanden från en av företagets hållbarhetsredovisningar i syfte att öka förståelsen för den narrativa kommunikationen. Dessa uttalanden och kommunikationsval diskuteras sedan utifrån ett intressentperspektiv. Studien fann att bolaget använder sig av retrospektiva resonemang då defensiviteten är låg och prospektiva resonemang vid interna initativ där offensiviteten är hög. Utöver detta återfanns även symboliska uttalanden. Resultaten tyder på att företaget använder olika typer av uttalanden för att hantera legitimitetsfrågor mot sina intressenter.

Descriptive menu labels are omnipresent elements in restaurant menus. Food service operations often use sensory, nostalgic, and brand descriptions to signal a customer's food-specific perceptions. Extant research has shown links between descriptive menu labels and food taste/enjoyment perceptions. To extend and expand the extant literature, this dissertation proposes that descriptive menu labels can be viewed as an anthropomorphizing factor, leading to different magnitudes of consumption-related attitudes and behavioral intentions in a restaurant. Drawing from metaphoric transfer theory and social impression models, the present research study suggests that descriptive labels in a restaurant transmit metaphors that influence consumers' impending warmth and competence perceptions of a restaurant. This dissertation also investigates the potential inversed magnitudes of anticipated satisfaction and willingness-to-pay-more driven by warmth/competence. In this empirical study, descriptive menu labels were experimentally manipulated. Consumers' warmth-related and competence-related service impressions, anticipated satisfaction, and willingness-to-pay-more more were measured. The empirical investigation comprised two pretests and one main study. The hypotheses were tested in two menu contexts (an entrée menu vs. a dessert menu). Overall, the results suggest that customers view a restaurant with sensory- and nostalgia-triggering descriptions as offering warmer impending services (i.e., with kindness, generosity, and understanding) compared to a restaurant with general descriptions. On the other hand, customers view a restaurant that utilizes brand-related descriptions as providing more competent and skilled impending services than a restaurant that utilizes general descriptions. In addition, the findings suggest that consumers' warmth impressions serve a more important role in their anticipated satisfaction than do their competence impressions; however, regarding willingness-to-pay-more, competence impressions factor more significantly than do warmth impressions. The replications of the results across the two menu contexts showed the robustness of the findings; however, there was a different pattern observed for the effects of sensory labels on consumers' warmth-related impressions in the dessert menu selection context. This dissertation contributes to emerging streams of menu labeling and service management literature. The findings presented in this dissertation have both theoretical and managerial implications for the food service industry. / Ph. D.
