An adapted building served as a military kitchen with a military club and an accommodation. The building was built in the 1950s. It is partly two storey basement building made of full baked bricks. Carrying and external constructions will be left unchanged. The old kitchen and dining room will be removed and replaced by a kindergarten and a gym on the 1st floor. There will be left in the original accomodation on the 2nd floor. In the cellar, there will be constructed a nightclub. All wooden windows and doors in the facade will be replaced by plastic ones. The building will be additionally insulated.

The subject of this thesis is a suggestion on mechanism for automatic interfacing of boring and facing heads with CNC U-axis on horizontal machining centres made in Tajmac-ZPS company. The thesis is terminated in modal analysis which is done in the point of view of the constructed boring head´s behaviour.

Even with the rise of racial diversity in the workplace, African American women remain underrepresented in upper management and organizational leadership positions, making up only 1% of U.S. corporate officers. The purpose of this qualitative narrative inquiry study was to explore the daily experiences of African American women middle managers in regard to stereotype threat and the effect of these experiences on their engagement with leadership aspirations. The narrative inquiry method was used to address this gap and answer the research question, through storytelling from African American women in middle-management positions. This study was framed by 2 key concepts that focus on minority group workplace experiences with stereotype threat and the implications of these experiences on minority group members for their engagement with leadership aspirations: Inzlicht and Kang’s concept of stereotype threat spillover and Major, Spencer, Schmader, Wolfe, and Crocker’s concept of psychological disengagement. The data-gathering process involved semistructured telephone interviews with 7 college-educated African American women, in U.S.-based organizations, in which participants told the story of their stereotype threat experiences in middle management roles. Two of the 5 key themes uncovered were impact of stereotype threat spillover and disengagement from leadership and career aspirations. The information gathered from the narrative study will help drive social change by bringing awareness to the issue and reducing threat experiences of disadvantaged groups across organizations.

Les travaux présentés dans le cadre de cette thèse de doctorat concernent la problématique d’arrachement de bâches de semi-remorques convoyés par le réseau d’autoroutes ferroviaires. En effet, les phénomènes turbulents générés autour d’un tel convoi provoquent d’importantes fluctuations de pression sur les parois bâchées, entrainant des mouvements de forte amplitude menant à la rupture sur de longues périodes de sollicitation. Ce phénomène pouvant provoquer plusieurs types d’incidents pour l’exploitant du réseau (embrasement par contact caténaire, retard des trains, perte de marchandise, etc...), il est nécessaire de comprendre les phénomènes physiques mis en jeu et de dégager une solution de contrôle de l’écoulement satisfaisant les contraintes de l’industrie ferroviaire. Pour ce faire, une étude expérimentale et numérique de l’écoulement autour d’une configuration bidimensionnelle de marche montante a été réalisée afin de caractériser l’influence des différentes zones décollées sur les fluctuations de pression pariétale induites en aval de la marche. A cet effet, une série de mesures de champs de vitesse et de pression pariétale ont été réalisées dans la soufflerie du Lamih. Les résultats observés expérimentalement ont pu être confrontés à ceux obtenus par une approche numérique dans des conditions équivalentes. L’analyse de l’écoulement s’est principalement focalisée sur deux points. Le premier concerne la dynamique des zones de recirculation en interaction avec la couche de cisaillement. Une approche stochastique a été déployée, et a permis de mettre en évidence les mécanismes prépondérants à l’origine du phénomène. Le second point porte sur les liens entretenus entre ces mécanismes et les fluctuations de pression pariétale. Une approche modale, basée sur une décomposition orthogonale aux valeurs propres étendue, a permis de révéler l’importante contribution des basses fréquences dans ce cas de figure. Enfin, une solution de contrôle passive (déflecteur) a été testée et a permis de montrer que la suppression de ces mécanismes basse fréquence permet d’obtenir un gain en termes de pression pariétale pouvant aller jusqu’à 36% selon les configurations. / The work presented in the framework of this doctoral thesis concerns the problem of the tarpaulins tearing off of semi-trailers conveyed by the motorways network. Indeed, the turbulent phenomena generated around such a convoy cause large pressure fluctuations on the walls, resulting in high amplitude movements leading to breakage over long periods of stress. This phenomenon can cause several types of incidents for the operator of the network (ignition by catenary contact, train delay, loss of goods,...), it is necessary to understand the physical phenomena involved and to define a flow control solution that take into account the rail industry constraints. To do this, an experimental and numerical study of the flow around a two-dimensional forward facing step configuration was carried out in order to characterize the influence of the different separated zones on the wall pressure fluctuations induced downstream of the step. For this purpose, a series of velocity field and wall pressure measurements were carried out in the Lamih wind tunnel. The experimental results could be compared with those obtained by a numerical approach under the same conditions. The flow analysis focused mainly on two points. The first concerns the dynamics of the recirculation zones interacting with the shear layer. A stochastic approach has been used, and has made it possible to highlight the dominant mechanisms at the origin of the phenomenon. The second point concerns the dynamical links between these mechanisms and the wall pressure fluctuations. A modal approach, based on an extended orthogonal decomposition, revealed the important contribution of the low frequencies in this case. Finally, a passive control solution (deflector) was tested and showed that the low frequency mechanisms suppression provide a wall pressure gain up to 36 % depending on configurations.

Bakgrund: Ett ständigt utvecklande av den fysiska modehandeln har lett till möjligheter att utveckla en shoppingupplevelse för konsument för att bemöta konkurrens från den digitala handelsplatsen. Detta har lett till att den fysiska butiken implementerar alternativ som teknologiska innovationer för att höja shoppingupplevelsen för konsumenten. Metod: Kvalitativ undersökning med 14 semistrukturerade intervjuer och tematisk analys av den insamlade empirin. Avgränsning är satt till att endast behandla konsumentinriktade teknologier. Resultat och analys: Resultaten av insamlade data bestående av respondenternas intervjusvar analyseras mot den tidigare forskningen. Resultatet visar att respondenternas självskattning av deras teknologiska kunskap påverkar deras användning av teknologier. Vissa av respondenterna påverkas också av socialt inflytande, både positivt och negativt. Även den upplevda säkerheten hos en teknologi påverkar respondenternas acceptans av teknologin. Olika slags värden upplevs av konsumenter där självständighet, tidssparande, smidighet och nöje är de fyra centrala teman som identifieras. Respondenterna upplever och prioriterar dessa värden olika, vilket också påverkar motiven för användandet av teknologiska innovationer. Diskussion: En vidare diskussion förs utifrån tidigare teori och insamlad empiri kring värde, teknologiska innovationer och acceptans. Resultatet diskuteras utifrån ett modehandelsperspektiv, där både fast och slow fashion diskuteras. Fast fashion butiker kan gynnas till större grad av att implementera teknologier som ökar konsumenternas självständighet. Märkesvaruhus som fokuserar på att kunna ge personlig service till sina konsumenter kan missgynnas av att implementera teknologi som missgynnar personlig service. Slutsats: Denna undersökning har bidragit med att ge en tydlig bild av hur konsumenter upplever teknologiska innovationer och vad som driver dem till att börja använda dessa. Förslag till vidare forskning kan därför vara fördjupat kring hur kunskapsbristen kring teknologiska innovationer påverkar konsumenternas användande och beteende, samt hur detta kan identifieras. / Background: A constant development of the physical fashion retail business has led to possibilities to develop a shopping experience for consumers to compete with the online marketplace. This has led to physical stores implementing technological innovations to enhance the consumer experience. Method: A qualitative study with 14 semi-structured interviews along with a thematic analysis being made to structure the collected data. The paper is delimited to only consumer facing technologies. Result and analysis: The results of the respondents’ answers are analysed from the previous research. The results show that the respondents’ self-evaluation of their technological knowledge affects their usage of technologies. Some of the respondents are also affected by social influences, both in a positive and negative way. The perceived security of a technology also affects respondents’ acceptance of the technology. Different kinds of value are experienced by the respondents, with independence, time saving, flexibility and pleasure being the four central themes. The respondents experience and prioritise these values differently, which also affects the motives behind using technological innovations. Discussion: The result is discussed from a fashion industry perspective, with fast and slow fashion being brought up as two major areas. Fast fashion stores can benefit from including technological innovations to increase the customers’ independence. High fashion brands with a strong focus on personal service might suffer from introducing such technologies, as it contributes to a loss of personal service. Conclusion: This paper contributes with a clear understanding of how consumers experience technological innovations and what drives them to become users. Suggestions for further research is presented and recommends a deeper study focusing on the lack of technological knowledge, how it affects the use of technological innovations in a retail environment and how it can be identified.

The development of new tools, systems, and mobile applications facilitate the tourist and hotel offer, make the distribution channels of their services reach more directly to their partners or final customer, resulting in better prices and prompt reply. Moreover, these technological advances generate susceptibility in professional development who faces new challenges and respond to the new demands. The travel agent must have the technical knowledge and should accelerate the response to customers with attractive and innovative proposals. Additionally, the traveler prefers the use of technology instead of needing the service of a travel agent. This behavior is repeated in the acquisition of hotel and air tickets since the booking is offered through virtual platforms and the traveler connects directly with them instead of needing the advice of a travel agent. The technology affects the pace in the markets and the technological knowledge is highly needed on the qualified professionals. / Trabajo de suficiencia profesional

abstract: Learning analytics application is evolving into a student-facing solution. Student-facing learning analytics dashboards (SFLADs), as one popular application, occupies a pivotal position in online learning. However, the application of SFLADs faces challenges due to teacher-centered and researcher-centered approaches. The majority of SFLADs report student learning data to teachers, administrators, and researchers without direct student involvement in the design of SFLADs. The primary design criteria of SFLADs is developing interactive and user-friendly interfaces or sophisticated algorithms that analyze the collected data about students’ learning activities in various online environments. However, if students are not using these tools, then analytics about students are not useful. In response to this challenge, this study focuses on investigating student perceptions regarding the design of SFLADs aimed at providing ownership over learning. The study adopts an approach to design-based research (DBR; Barab, 2014) called the Integrative Learning Design Framework (ILDF; Bannan-Ritland, 2003). The theoretical conjectures and the definition of student ownership are both framed by Self-determination theory (SDT), including four concepts of academic motivation. There are two parts of the design in this study, including prototypes design and intervention design. They are guided by a general theory-based inference which is student ownership will improve student perceptions of learning in an autonomy-supportive SFLAD context. A semi-structured interview is used to gather student perceptions regarding the design of SFLADs aimed at providing ownership over learning. / Dissertation/Thesis / Masters Thesis Educational Psychology 2019

Traditional transport companies usually focus on achieving economies of scale in supply chain management. At the same time, the managers of transport companies aiming to achieve sustainability often do not consider the barriers needed to overcome to achieve a sustainable supply chain. However, due to the increasing demand for sustainable products and business methods, sustainable supply chain management increasingly plays a crucial role in changing and diverting the focus on environmental, social and economic impact. Transport companies around the globe are increasingly aiming to reduce carbon emissions and eliminate biodiversity loss. The sustainability issues with transport in supply chain management have been a critical field of research for decades, and with the integration of technology, new ways of achieving sustainability are possible. This thesis analyses a phenomenon using multiple cases to investigate the barriers transport companies face to adopting IoT. Also, it deals with how communication service providers might be able to offer solutions to the barriers presented in this thesis.  A qualitative method has been used to approach the research topic. The findings will represent the ways of achieving a more efficient and sustainable supply chain, particularly in the transport sector. Interviews were conducted with multiple industry experts. The study aims to identify the barriers to adopting IoT, which can create a sustainable supply chain for transport companies. The results emphasise the barriers transport companies have to deal with internally and externally. Internally a company might struggle to strategise an infrastructural investment, train the existing workforce, and collaborate knowledge share among different departments. Externally, transport companies or communication service providers (CSP) will face limited resources, stakeholders' investment in the IoT ecosystem, demand for IoT and sustainable supply chain, privacy issues, compatibility issues and lack of skilled labour.
