Tick tock, tick tock : A qualitative study of how millennials impulse buying behavior is influenced by limited-time promotion in Sweden

Petersson, Victoria, Brink, Frida January 2022 (has links)
In recent years, the sales promotion techniques provided by marketing strategies has increased and has become an important factor in the fashion industry. In todays society customers have more knowledge and easier access to information online. Due to the growth of consumer awareness, businesses need to gain insight on how limited-time promotion techniques affect consumers.  Accordingly, the purpose is to gain insight and understand how millennials' impulse buying is influenced by limited-time promotion when purchasing fashion products online, and explore if hedonic and utilitarian motivation appear and lead millennials to a purchase decision. The aim is to develop a more recent and essential knowledge within this topic due to the poverty of recent studies on if limited-time promotion influences millennials impulse buying behavior.  The empirical findings that were collected using a multiple-method qualitative study of four focus-groups and six semi-structured interviews with people originated from Sweden. The findings were analyzed and discussed with the literature that have been presented to determine their similarities or differences.  The conclusion of this thesis demonstrates millennials in Sweden's awareness of businesses marketing strategies, and that they are detached to the process. Throughout the thesis, millennials' attitudes towards the businesses promotions in the market is saturated, and that they are not influenced by limited-time promotion online since the knowledge that there will soon occur a discount again. Although the increased awareness of millennials in Sweden, utilitarian and hedonic motivations tend to create impulse-buying behavior online. Furthermore, to attract millennials in Sweden some factors have been identified.

Buy 2 for the price of 1 : A multiple case study of how grocery stores influence consumers impulse buying behavior online

Adolfsson, Tess, Schönström, Isabell January 2021 (has links)
There has been a significant increase in e-commerce over the past years and to which extent consumers use it. During the past year, when the Covid-19 pandemic has ravaged among us, food consumption has also become a fact. Grocery stores have had the opportunity to develop their e-commerce and offer their customers a chance to purchase products at any time suitable. As the market is evolving, the concept of consumer behavior and impulse buying behavior has become more relevant and exciting in research. Still, little research has been done regarding how grocery stores influence consumers’ impulse buying behavior when shopping for groceries online.  The purpose of this research, from a business perspective, is to investigate how grocery companies influence consumers' impulse buying behavior online and to identify if there are any contributing factors to influencing this behavior. The aim is to develop a more profound knowledge within this topic due to the lack of previous research on impulse buying behavior when shopping for groceries online.  The conclusion of this thesis shows that impulse purchases increase the additional sales to the store and that there are clear strategies for how the grocery stores do to influence the impulse buying behavior in the physical store. However, the study showed that grocery stores do not actively work to influence consumers' impulse buying behavior when shopping for groceries online as they do not have the power to implement them. This is because the head offices control their e-commerce.

Is social media the new drug that generates impulse buying? : A quantitative study on social media´s effect on impulse buying regarding fashion products and if it differs between men and women in Sweden

Lennartsson, Lina, Zeka, Adelina January 2021 (has links)
Social media is a phenomenon that is successively developing, and the usage is rising each day, which in turn has an impact on consumer behaviour. Hence, the new attributes that social media provides, both for businesses and individuals, are affecting the way people are acting when making a purchase. Due to these circumstances the purpose of this thesis was to investigate and understand how social media are affecting consumers impulse buying behaviour when purchasing fashion products, and to establish if there were any gender differences.  From previous research about impulse buying and the online environment, seven hypotheses were created. The empirical findings were conducted using a quantitative method through an online survey with standardized and mainly closed-ended questions. The data were collected from 375 respondents, whereby there were at least 100 of each gender. Following, all the hypotheses were tested through the statical software SPSS.  In the conclusion of the thesis, it is established that two triggers, market stimuli and individual traits, had a moderate effect on consumers impulse buying tendency while the other categories did not at all. However, it was confirmed that all triggers had a correlation to impulse buying on social media. Additionally, it was determined that there were a gender differences in all the tested hypotheses, proving that there is a difference between men and women regarding impulse buying on social media. Although, the research is providing space and opportunity to include other aspects and develop the research field further in future research.

Klinischer Nutzen von Abdomensonographie und Leberelastographie zur Prädiktion und Diagnostik von Komplikationen bei allogener Stammzelltransplantation

Kunde, Jacqueline 04 February 2016 (has links) (PDF)
Die vorliegende medizinische Dissertation untersucht nicht-invasive bildgebende Verfahren wie die konventionelle Sonographie, die Acoustic radiation force impulse (ARFI)-Elastographie sowie die Transiente Elastographie (TE) zur Detektion von Komplikationen in der Frühphase nach allogener Stammzelltransplantation. Dem kurativen Therapieansatz der Stammzelltransplantation steht ein hohes Komplikationspotential gegenüber. Besonders hepatobiliär treten Graft-versus-host Erkrankungen (GvHD) sowie Gefäßkomplikationen (VOD) auf. Der bisherige diagnostische Goldstandard, die Leberbiopsie, ist als invasives Verfahren mit einer hohen Intra- und Inter-Untersucher-Variabilität sowie der geringen Repräsentativität als Screeningmethode ungeeignet. Die Elastographieverfahren ARFI und TE als nicht-invasive Alternativen ermitteln die Lebergewebesteifigkeit als Surrogatparameter fibrotischer Veränderungen und wurden bereits in zahlreichen Studien als geeignete Diagnoseverfahren für Leberfibrose und -zirrhose unterschiedlicher Ätiologie definiert. Ziel dieser prospektiven Pilotstudie war die Evaluation der genannten Methoden zur Detektion von Frühkomplikationen nach allogener Stammzelltransplantation. Die Ergebnisse der Studie zeigen, dass sowohl die konventionelle Sonographie als auch die Transiente Elastographie pathologische Organveränderungen vor allem des hepatobiliären Systems detektieren können. Allerdings erscheinen diese Veränderungen unspezifisch. Es bestehen keine signifikanten Unterschiede zwischen Patienten mit und ohne Komplikationen. Anders bei der ARFI-Elastographie. Hier zeigten die Messwerte im linken Leberlappen signifikant höhere Werte bei Patienten mit Komplikationen. Zusammenfassend ist die ARFI-Elastographie zur Prädiktion möglicher Komplikationen nach allogener Stammzelltransplantation geeignet, sollte allerdings mit anderen diagnostischen Verfahren ergänzt werden.

Análise da influência de diferentes geometrias de retificador de fluxo no desempenho de um sensor tipo \"impulse swirl meter\" utilizado para medição de cabeçotes. / Analysis of influence for different flow straightener geometries in the performance of sensor type \"Impulse Swirl Meter\" used to swirl measurement in cylinder heads.

Camata, Mauricio Bishop 16 November 2016 (has links)
O número de swirl de um cabeçote de motor de combustão interna pode ser medido pelo método de vazão em regime permanente. Nesse método o ar é forçado através do cabeçote para diferentes aberturas de válvula. O sensor comumente utilizado nas plataformas para a medição do swirl é o do tipo ISM (impulse swirl meter) que utiliza um retificador de fluxo como o componente principal para capturar o momento angular de rotação do fluxo de ar. Esse trabalho visa encontrar as dimensões geométricas para o retificador de fluxo utilizado em sensor tipo ISM, de tal forma que esse retificador possibilite a realização das medições com a menor interferência possível no resultado final. Dezesseis retificadores de diferentes dimensões foram construídos a partir do processo conhecido como prototipagem rápida. Vários ensaios foram realizados em uma plataforma que utiliza o método de vazão em regime permanente para a medição de swirl em cabeçotes. Para todos os ensaios foi utilizando um mesmo cabeçote de motor diesel como gerador de swirl. No capítulo conclusões são apresentadas as dimensões geométricas que resultaram em menor interferência no fluxo e uma maior eficiência do sensor, bem como sugestões para trabalhos futuros. / The swirl number of a cylinder head can be measured by a steady state flow method in which air is forced through the cylinder head for different valve openings. The sensors commonly used on the swirl measurement platform are of the ISM type (impulse swirl meter) that use a flow straightener as the main component to capture the rotational angular momentum of the air flow. This study objective is to determine the geometric dimensions for the flow straightener used in the ISM sensor, which still allows the measurement but causes the least interference on the measurement result. Sixteen different flow straighteners were constructed by rapid prototyping process. Several tests were performed on a platform that uses the steady state flow method to measure the swirl number of cylinder heads. For all tests the same cylinder head was used as swirl generator. The conclusion chapter presents the geometric dimensions that caused the least interference in the flow and resulted in a greater sensor efficiency, as well as suggestions for future studies.
