The blended wing body (BWB) is a tailless aircraft with the potential to use 27% less fuel than a conventional aircraft with the same passenger capacity and range. The primary purpose of the current study was to determine the handling qualities of the BWB, using piloted-handling trials in a moving-base simulator. The secondary purpose was to determine the effect of simulator motion on handling-quality ratings. De Castro conducted piloted-handling trials in a fixed-base simulator. De Castro's tasks and flight model were modified in the current study. In the current study, three subjects rated the handling qualities as Level 1 or 2, depending on the task. Simulator motion did not have a significant effect on the results.

The aim of this study was to describe ways in which Grade 1 teachers use creative teaching practice in Mathematics. An interpretivistic approach was used with qualitative research principles guiding the research process. The research design was a case study design. Three primary school teachers at an Afrikaans private school were purposefully selected. A multi-method approach to data gathering was taken. Firstly, the Curriculum and Assessment Policy Statement (Foundation Phase): Mathematics was analysed to determine the guidelines of the Department of Basic Education regarding creative teaching practice in Mathematics. Secondly, the three participants each made a visual representation (poster) of their understanding of creative teaching practice in Mathematics, where after each participant's poster was discussed with her. Thirdly, a total of five Mathematics lessons were observed and one semi-structured interview was conducted with each participant. Fourthly, personal opinions, reflective thoughts and impressions of the research study were noted in the researcher's research journal. Results were derived from inductive thematic analysis of the documented data. After member checking, four themes were identified. Firstly, some fundamental principles for the use of creative teaching practice in Mathematics were deducted, which included sensitivity for learner differences, the use and development of learners' current knowledge, active learner participation in lessons, interest and joy in Mathematics lessons, and the inclusion of the life world of the learners in the Mathematics lessons. Secondly, the participants suggested possible implementation strategies for creative teaching practice in Mathematics, namely the implementation of problem solving skills, concrete experiences and resources, group learning and social interaction. Thirdly, some teacher qualities that promote creative teaching practice in Mathematics were indicated, namely teachers as specialist subject experts in Mathematics, motivators of learners, creators of a positive learning and teaching environment, interpreters and designers of learning programmes and material, and adaptability. The fourth theme emphasized the challenges regarding the use of creative teaching practice in Mathematics where environmental factors were indicated. Based on the findings the conclusion can be made that domain relevant skills, skills regarding creativity, intrinsic task motivation and the social environment are components that can be incorporated to promote the successful use of creative teaching practice in Mathematics. / Die doel van hierdie studie was om te beskryf op welke wyses Graad 1-onderwysers kreatiewe onderrig in Wiskunde gebruik. Die studie is vanuit 'n interpretivistiese benadering onderneem met kwalitatiewe navorsingsbeginsels wat die navorsingsproses onderlê het. 'n Gevalstudie-ontwerp is as navorsingsontwerp gebruik. Drie laerskoolonderwysers, verbonde aan 'n Afrikaanse privaatskool, is deur 'n gerieflikheidseleksie geselekteer. Data is deur 'n multi-metodiese benadering versamel. Eerstens is die Curriculum and Assessment Policy Statement (Foundation Phase): Mathematics ge-analiseer, om sodoende die Department van Basiese Onderwys se riglyne betreffende kreatiewe onderrigpraktyk in Wiskunde te identifiseer. Tweedens het die drie deelnemers elk 'n visuele voorstelling (plakkaat) gemaak wat hul begrip aangaande kreatiewe onderrigpraktyk in Wiskunde uitbeeld, waarna elke deelnemer se plakkaat met haar bespreek is. Derdens is vyf Wiskunde-lesse in totaal waargeneem en een semi-gestruktureerde onderhoud met elke deelnemer gevoer. Vierdens is persoonlike opinies, reflektiewe gedagtes en indrukke van die navorsingstudie aangeteken in die navorser se navorsingsjoernaal. Induktiewe tematiese analise van die gedokumenteerde data het gedien as basis vir die resultate. Deelnemerkontrole is uitgevoer en vier temas is geïdentifiseer. Eerstens is van die fundamentele beginsels vir die gebruik in kreatiese onderrigpraktyk in Wiskunde afgelei, wat insluit sensitiwiteit vir leerderverskille, die gebruik en ontwikkeling van leerders se bestaande kennis, aktiewe leerderbetrokkenheid by lesaanbieding, interessantheid en genotvolheid van Wiskunde-lesse, en die insluiting van leerders se leefwêreld by Wiskunde-lesse. Tweedens het die deelnemers moontlike implementeringstrategieë vir kreatiewe onderrigpraktyk in Wiskunde aangedui, naamlik die implementering van probleemoplossingsvaardighede, konkrete ervaringe en hulpbronne, groepsleer en sosiale interaksie. Derdens is sommige onderwyserkwaliteite ter bevordering van kreatiewe onderrigpraktyk in Wiskunde aangedui, naamlik onderwysers as spesialis vakkenners in Wiskunde, leerder-motiveerders, skeppers van 'n positiewe leer- en onderrigomgewing, interpreteerders en ontwerpers van leerprogramme en -materiaal, en aanpasbaarheid. Die vierdie tema het die uitdagings rondom die gebruik van kreatiewe onderrigpraktyk in Wiskunde beklemtoon, waar onder andere omgewingsfaktore aangedui is. Op grond van die bevindinge kan die gevolgtrekking gemaak word dat domein-relevante vaardighede, kreatiwiteitsvaardighede, intrinsieke taakmotivering en die sosiale omgewing komponente van die samestellende teorie van kreatiwiteit (Amabile, 2012) is, wat ingesluit kan word om die suksesvolle gebruik van kreatiewe onderrigpraktyk in Wiskunde te bevorder. / Dissertation (MEd)--University of Pretoria, 2016. / Educational Psychology / MEd / Unrestricted

The purpose of the study is to explore in what ways leadership qualities such as delegation in the Fintech sector is different to that of traditional financial sector in times of crisis. The study is conducted during the COVID-19 pandemic crisis. The findings of this study may theoretically add to the discussion topic for further research on leadership and delegation in times of crisis. From a practical perspective the findings can give leaders insight on what a select group of entrepreneurs in the Fintech sector perceive as important leadership qualities and delegation in times of crisis. A qualitative study was conducted featuring semi-structured interviews with nine leaders in the Fintech sector. An abductive research method has been used, moving back and forth between theory and research and from the empirical evidence identify the common themes of the most important in leadership qualities. The analyses of the empirical evidence showed that there are a few points that support both theory and practice in this specific crisis being, leaders in crisis need to be authentic, trusting, and transparent and have the ability to communicate it to the stakeholders. Although the leadership qualities in crisis varied, there were a few common themes; the importance of trust and qualities such as the ability to take decisions, give clear direction and communication are all in line with theory. What specifically stands out in the Fintech sector, making it different from that of more traditional industries, is that the leadership includes an increased willingness and ability to delegate. Delegation in times of crisis is important as it empowers the team which could further add to a positive resolve of the situation. One of the prerequisites to be able to delegate is the team being experts in their specific area, the other was their mindset and attitude. Fintech leaders also have the notion that leadership in crisis should be the same as is in times of non-crisis and it is imperative to continue to be delegating. The difference compared to more traditional industries can be contributed to entrepreneurial mindset of leaders in the Fintech sector being used to uncertainty and day to adversity of business survival, always ready to adapt their business model. An area for further research could be to do a wider scope and how the crisis affects other sectors.

When developing an aircraft, one of several important aspects is to predict and properly design the dynamic behaviour of the aircraft. This holds for manned aircraft as well as for UAVs. The optimal dynamic behaviour for an aircraft depends on the mission or purpose: for a certain use an aircraft should be agile, other may require a more stable one. In aeronautics, the properties that describe the aircraft ecacy with respect to some task are known as ying qualities, and our goal is to study their dependence on some design parameters. As a test model we use an existing UAV. After deriving its 6-DOF dynamic model and assessing its baseline characteristics, we perform parametric studies. The strategy followed is divided in two steps: the rst consists on analyzing ying qualities sensitivity to changes in model parameters. The second step studies how specific design changes affect model parameters. Because the rst step only depends on the dynamic model form, we verify, by testing two other dierent aircrafts, that conclusions drawn from this step are valid to other congurations. Finally we show how results from parametric studies can be used to improve the UAV ying qualities regarding a certain mission, through the introduction of slight modications on baseline design.

Könets relation till uppfattat ledarskap har studerats i decennier. Vissa studier framför motsättningen mellan den kvinnliga könsrollen och ett uppfattat effektivt ledarskap, andra studier menar att det inte föreligger skillnad beträffande hur ledarskap mellan könen uppfattas. Ålderns relation till uppfattat ledarskap har framförallt på senare tid studerats. Somliga studier framför att ålder har en effekt kring förväntningar på ledarens ledarbeteende, medan detta dementeras i andra studier. Syftet var att undersöka om kön och ålder samvarierar med hur ledarbeteenden uppfattas. Variablerna undersöktes med utgångspunkt ur en integrering av forskningsresultat där sex ledarbeteenden framstod som essentiella för ledarskap. Urvalet bestod av 123 universitetsstudenter som besvarade studiens enkät. Databearbetning skedde genom sex tvåvägs ANOVOR för oberoende mätningar. Resultatet visade att kön och ålder inte relaterar till hur ledarskap uppfattas, med undantaget att yngre ledare skattades inneha högre Inre kontrollokus. Studiens resultat beträffande könets relation till uppfattat ledarskap går i linje med nutida forskning.

Studiens syfte var att undersöka hur arbetstagarna vid en statlig organisation i Mellansverige upplevde ledarskap under distansarbete. Åtta semistrukturerade intervjuer genomfördes och analyserades med en induktiv tematisk analysmetod för att uppnå syftet. Resultatet visade tre huvudteman som representerade respondenternas subjektiva upplevelse av distansledarskap. Enligt respondenterna krävdes en ledare med personlig mognad för att kunna leda på ett önskvärt sätt. Tydlighet i kommunikationen och förmågan att skapa förtroende ansågs också vara avgörande egenskaper, särskilt vid distansarbete för att upprätthålla medarbetarnas välbefinnande. Sammanfattningsvis framkom det att bra kommunikation och förtroende var nyckelfaktorer för att skapa ett positivt ledarskap. En kommunikativ och empatisk ledare inkluderade och engagerade sina anställda, särskilt vid distansarbete. / The purpose of the study was to examine how employees in a state organization in central Sweden experienced leadership during remote work. Eight semi-structured interviews were conducted and analyzed using an inductive thematic analysis method to achieve the objective. The results revealed three main themes representing the respondents' subjective experience of remote leadership. According tothe respondents, a leader with personal maturity was required to effectively lead. Clarity in communication and the ability to build trust were also considered crucial qualities, especially in remote work, to maintain employee well-being. In summary, effective communication and trust were key factors in creating positive leadership. A communicative and empathetic leader included and engaged their employees, particularly in remote work settings.

This thesis aims to analyze the “tension” in video games by using an experiment-based practical approach. It examines different lighting conditions and how people perceive them in virtual environments. “Flow Theory”  and “Circumplex Model” are used as theoretical frameworks to define the term tension and serve as the basis of the experiment. For the experiment, a scene is created primarily inspired by the video game Resident Evil: Village. Different lighting conditions are applied to the scene in order to understand how lighting qualities can invoke various emotions in the context of tension. A survey is conducted on people with diverse backgrounds to observe their reactions and understand their perception  of their surroundings.
