Trust Issues? : An explorative study about millennials understanding of trust at work

Amoako-Atta, Christopher, Le Persson, Timmy January 2020 (has links)
Through demographic change, millennials now make up the most substantial part of the workforce. This is relevant as they are also a generation faced with prejudice. This thesis aims to explore how millennial followers are looking at trust in work relationships and how they perceive to establish trust in work relationships to increase understanding. The focus of this study is on millennial followers, as leadership literature is plentiful, and most millennials are and will always be followers.  We examine the millennials’ understanding of trust and explore what issues they bring up when reflecting on trust at work. This thesis argues that millennials think of trust as relying on others when thinking of healthy relationships. They prefer knowledge-based relationships over calculus- and identity-based relationships. To build trust, millennials perceive that they use both task- and relationship-based trust-building together with interactions as based to earn and evolve trust. In relationships where there are trust issues, they change their understanding of trust and stick to task-based or calculus-based relationships. This study follows an interpretivist approach with an abductive structure. For data collection, indepth interviews with 7 millennials from Sweden and Switzerland were conducted. To analyze a thematic approach to coding was employed. The emerging patterns are introduced in a thematic narrative to increase comprehensibility. The study provides insights into the millennial followers’ understanding of trust.

The effects of authentic leadership and a positive organisational context

Sassoon, David 03 July 2011 (has links)
This research concerns itself with the effects of authentic leadership and a positive organisational context. Gardner, Avolio, Luthans, May and Walumbwa’s (2005) authentic leader and follower development model suggests that authentic leadership within a positive organisational context leads to increased authentic followership, which in turn influences positive follower outcomes, and finally leads to sustainable and veritable organisational performance. A research contextual framework, based on Gardner et al.’s (2005) model, is developed with one significant change being the repositioning of a positive organisational context as a relatively more significant construct in the development of authentic followership. The research contextual framework and in particular the correlations between the various constructs are tested. This is performed through a quantitative study based on the completion of a research questionnaire by employees at four South African based services companies. In addition to a general testing of the various correlations, the role of a positive organisational context is specifically investigated in order to shed light on which model better reflects the authentic leadership development process: Gardner et al.’s (2005) model or the research contextual framework. It is also intended that this research will provide insights into whether general authentic leadership theory can be generalised to a South African context.

Do followers follow? : Social trading platforms and their effect on the stock market

Brinkfält, Hugo, Giersbach, Anna Lena January 2022 (has links)
Social trading platforms are an increasingly popular venue for sharing investment ideas. We investigate if followers on these platforms herd, i.e., copy leader traders’ trades, to the extent that it affects stock markets. To do so, we use an event study to detect abnormal returns and trading volume after a trade is conducted by a leader trader. Furthermore, we investigate if the leader trader’s sentiment on the stock and the leader trader’s perceived trustworthiness have explanatory power over the herding behavior. We find signs of herding in terms of abnormal returns within thirty-minutes after the leader trader’s trade. However, we do not find signs of herding for longer event windows, nor do we find that the sentiment of the leader trader can explain herding. Finally, we find some signs that affect-based signals of trustworthiness can explain herding. However, most signals of trustworthiness are non-significant.

Automated vehicle follower system based on a monocular camera / Automatiserat fordonsystem for foljning baserat pa en monokular kamera

JOHANSSON, JACOB, SCHRÖDER, JOEL January 2016 (has links)
This report proposes a solution for an automated vehicle follower based on one front-facing monocular camera that can be used to achieve platooning for a lower cost than the systems available on the market today. The sensor will be local to the automated follower vehicle, i.e. no Vehicle-to-Vehicle (V2V) communication. A state-of-the-art chapter describes di erent aspects of platooning, computer vision techniques, state of the art hardware developed especially for autonomous driving as well as systems closely related to the proposed solution. The theory behind the performed implementations such as trajectory, controls, image operations and vehicle models will be presented, followed by a chapter dedicated to the actual implementation. The experimental vehicle used to validate the solution was a modied 1=12 scale radio controlled (RC) car. An Arduino controls the steering and driving motor, and a PC mounted on the vehicle uses a webcam to capture images. The preceding vehicles position relative the follower vehicle was calculated from captured images from the webcam and a trajectory towards the preceding vehicles path was generated from a cubic curve. Measurements from a stereo vision system was used to evaluate the accuracy of the follower vehicle and minimal spacing needed between follower and preceding vehicle. The follower vehicle satisfy the behavior of following a preceding vehicle, but the accuracy of the follower vehicle should be improved to generate a more accurate trajectory before being tested on a larger scale vehicle. The solution shows that a monocular camera can be used to follow a vehicle, and with implementation of a GPS module and a fuzzy velocity controller it could be used to test on a full sized vehicle. / Denna rapport foreslar en losning som gor det mojligt att automatisera ett fordon genom en monokular kamera som foljer en framforvarande ledbil som skulle kunna anvandas inom platooning for en lagre kostnad an de losningar som nns pa marknaden idag. Sensorn ar lokal till det automatiserade fordonet och anvander sig inte utav V2V kommunikation. Ett state-of-the-art kapitel beskriver olika aspekter inom platooning av fordon, datorseende, specikt framtagen hardvara for automatiserade bilar samt automatiserande system som nns inkluderade i bilar idag. Teorin bakom implementationen av bilens trajektoria, reglerteknik, bildbehandlingsoperationer och fordonsmodeller presenteras ocksa. Teorin anvands sedan for att utveckla en prototyp som anvands till att besvara forskningsfragorna. Prototypfordonet ar en modierad radiostyrd bil i skala 1/12. En Arduino styr drivmotor och styrning medan en PC monterad pa bilen anvander sig av en webbkamera for att ta bilder. Ledbilens position relativt foljbilen beraknas med hjalp av bilderna och en bana att folja efter genereras av en tredjegradskurva. Matningar genom ett stereo vision system anvandes for att besvara fragor angaende noggranheten for den utvecklade efterfoljande bilen samt lagsta sakra avstand som kan anvandas mellan bilarna. Den utvecklade prototypbilen foljer efter ledbilen pa ett onskvart satt, dock borde trajektorian som den foljer utvecklas mera innan testning utfors pa storre fordon. Losningen pavisar att en monokular kamera kan anvandas for att folja efter en bil. Om systemet utokas med en GPS modul och en fuzzy hastighetskontroll kan denna losning testas med bilar i full storlek.

Silent Followers! : A Qualitative Study on the Factors Behind Low Comment Engagement Among Luxury Brand Followers on Instagram

Kayyal, Lara, Karkoor, Shahed January 2023 (has links)
This research explores the reasons why followers of luxury brand Instagram accounts engage less frequently through commenting despite having a large number of followers. The study addresses the research question: "Why do Instagram followers of the luxury brand engage less through comments despite having a large number of followers?". The findings indicate that several factors contribute to the lower engagement through comments among Instagram followers of luxury brands. Firstly, a lack of active encouragement from luxury brands to interact and engage with their followers on Instagram leads to fewer comments and engagements on their posts. Algorithmic factors, such as the visibility of likes and comments, also influence engagement behavior, with followers more likely to comment on posts with a larger number of likes and comments. The authenticity of the content and engagement of luxury brands on Instagram plays a significant role, as followers tend to engage more with brands that come across as genuine and authentic in their interactions. Moreover, the exclusive image of luxury brands creates a perceived distance between the brand and its followers, which may discourage engagement through comments.  The study provides theoretical implications by highlighting the importance of active encouragement from luxury brands, the role of Instagram in brand differentiation, and the influence of algorithmic factors on engagement behavior. Managerially, the research suggests that luxury brand managers and marketers should actively encourage commenting and engagement, focus on producing authentic content, consider algorithmic factors, and create inclusivity to encourage engagement from followers.  The research project contributes to the understanding of engagement behavior on Instagram, providing insights for academics and valuable information for luxury brand managers and marketers to develop effective Instagram marketing strategies. Limitations focus on Instagram and comments as a measure of engagement, the limited sample size, and the neglect of influencers and sponsored content. Future research could explore other social media platforms, expand the scope of engagement measures, increase sample size, and consider the impact of influencers and sponsored content on customer engagement.

Autonomous Counterbalance Forklift : Autonomous forklift capable of transporting pallets / Autonom Motviktstruck

Boczar, Ludvig, Myrsten, Felix January 2019 (has links)
This thesis explored the possibility to use line following technology to automate forklifts in a warehouse scenario. This was done to reduce the need for staff to always be present in the warehouse. A prototype forklift was constructed with three wheels, where driving and steering was done by the rear wheel. To control the forklift an Arduino Uno was used. The line following was done using Infrared Radiation (IR) sensors. Different setups of line following sensors were tested to achieve a forklift capable of following a line. Different layouts of the operating area were also tested. Line following was found to work best when two sensors were placed in front of the front wheels when going forward and two by the back wheel when reversing. The conclusion was made that a setup of four sensors was enough to achieve a line following forklift. For the operating area, the best layout was found to be an X-shaped one. Using 90° corners proved to be the easiest to navigate. / Denna avhandling undersökte möjligheten att använda linjeföljningsteknologi för att automatisera gaffeltruckar i ett varuhus. Detta gjordes med målet att minska behovet på att alltid ha personal närvarande. En gaffeltrucksprototyp konstruerades med tre hjul, bakhjulsdrift och styrning på bakhjulet. För att styra gaffeltrucken användes en Arduino Uno. Linjeföljningen utfördes av IR sensorer. Tester utfördes på olika konfigurationer av linjeföljarsensorerna för att uppnå linjeföljning. Utformningen på arbetsområdet testades också. Linjeföljning visade sig fungera bäst när två sensorer var placerade framför framhjulen när man körde framåt och två vid bakhjulet när man backade. Slutsatsen blev att fyra sensorer var tillräckligt för att uppnå linjeföljningsförmåga. Den bästa utformningen på arbetsytan konstaterades vara en X-formad yta. Att använda 90° hörn visade sig vara lättast att navigera genom.

An examination of relationships between social media follower interactions and novice piano students’ music performance anxiety and self-esteem

Hejjawi, Lina K. 25 August 2023 (has links)
Online communication is a common component of contemporary life. However, research into its impact on well-being has found conflicting results. Although social media may have a detrimental impact on well-being, particularly in young adults (O’Reilly et al., 2018), some studies have found social media networking to have a beneficial influence on well-being (Ellison et al., 2007; Kim, 2017), which may contribute to improved academic performance among students (Al-Rahmi & Othman, 2013). The potential for such effects to extend to musicians in their experience of music performance anxiety (MPA) was the impetus for the current qualitative study, whose purpose was to explore friend and follower engagement on social media and its connection to self-esteem and MPA, using the PERMA Model (Seligman, 2011) to guide the inquiry. Six novice college-aged piano students completed State-Trait Anxiety (STAI-S) and Coopersmith Self-Esteem (CSEI) inventories, a demographic and social media use questionnaire, and two individual semi-structured interviews. Data were collected (1) at the outset of the study; (2) (a) after posting a short video excerpt of the piano performance on social media platforms and interacting with friends and followers, and (b) 30 minutes before the official performance at a live event; and (3) after the completion of the live performance. The findings suggest potential benefits of social media networking on novice music students’ well-being, Self-Esteem, and MPA. Social media interaction with friends and followers and novice piano students was frequently noted as a positive and significant contributing element to and preparation for participants’ successful performances. The awareness of the PERMA model assisted some participants in experiencing positive emotions, improving their well-being, elevating their self-esteem, and lowering their MPA. The feelings of happiness and well-being included in PERMA were linked to improved relationships between participants and their social media friends and were reported to improve their motivation, mastery, and achievement of goals, as well as feelings of support and encouragement. Negative comments did not affect participants with high self-esteem; however, it was not possible to observe the effects of negative comments on participants with low self-esteem since the one student with low self-esteem did not receive negative feedback. Despite findings from previous studies on the challenges and negative impacts of social media networking on students’ well-being, results of the current study indicate that it has the potential to be used positively. Mindful use of social media platforms may be an effective tool to help music students showcase their interests, talents, and achievements. As such, teachers may consider building strategies into their lessons to help students use social media as a learning tool for performance preparation. More research is needed on larger and more diverse groups of musicians to better understand the role of social media networking in music performance and its impact on musicians’ experience of MPA. Strategies for improving the practice and effectiveness of sharing music performances on social media platforms are discussed as pedagogical and performance-readiness tools. This study provides a starting point for music educators, administrators, and students in developing a more comprehensive understanding of the potentials and/or drawbacks of social media networking with regard to self-esteem and MPA.
