Hur beskrivs sensoriska egenskaper inom deskriptiv analys? : En kvantitativ tvärsnittstudie av artiklar publicerade 1974-2019 / Sensory attribute description in descriptive analysis : A quantative cross sectional study of articles published 1974-2019Apelman, Linnea January 2021 (has links)
Bakgrund Deskriptiv sensorisk analys (DSA) syftar till att beskriva sensoriska egenskaper (attribut) hos livsmedelslprodukter. En bedömarpanel analyserar ett produktprov genom att identifiera, namnge och mäta intensiteten hos ett antal attribut. Syfte Syftet med undersökningen var att studera hur attribut identifieras, beskrivs och presenteras inom vetenskaplig tillämpning av DSA. Metod Sjuttiofyra artiklar, publicerade i vetenskapliga tidskrifter mellan 1974 och 2019, analyserades kvantitativt med hjälp av deskriptiv statistik. Sjutton variabler användes för datainsamling. Samband mellan variablerna analyserades med hjälp av statistiska tester. Resultat Av artiklarna var 96 % publicerade i tidskrifter utan specifik inriktning mot sensorisk analys. I två tredjedelar av artiklarna tillämpades generisk deskriptiv analys (GDA). I fler än hälften av artiklarna avvek panelen från vad som rekommenderas kring bedömarantal eller tid för träning. I snitt användes 1,4 ord för namngivning av attributen. I hälften av artiklarna definierades inte attributen. I två tredjedelar av artiklarna presenterades inte några referensprodukter för att illustrera skalstegen. I tre fjärdedelar av artiklarna presenterades attributen i metodbeskrivningen. Meddelandelen substantiv var 68,2 % och 31 % adjektiv. En måttlig negativ korrelation mellan andelen substantiv och tiden för träning av bedömarpanelen var statistiskt signifikant. Slutsats I många vetenskapliga studier utförs DSA utan att gällande rekommendationer kring bedömarpanelen följs. I artiklar publicerade i vetenskapliga tidskrifter presenteras attributen inprecist nog att ifrågasätta användbarheten hos resultaten. Att ge den kvalitativa delen av undersökningen, identifiering och namngivning av attributen, status resultat skulle kunna öka intresset för att definiera attributen och illustrera skalstegen, vilket är en förutsättning för att tolka det kvantitativa resultatet (intensitetsmätningen) på ett meningsfullt sätt. / Background Descriptive sensory analysis (DSA) aims to describe the sensory attributes of food products. A panel of assessors analyze a sample of the product to identify and name a set of attributes and estimate their intensity. Objective The aim of the study was to research how attributes are identified, described and presented in the scientific use of DSA. Method By using descriptive statistics, 74 articles published in scientific journals between 1974 and 2019 were analyzed quantitatively. Data collection was conducted using 17 variables. Correlations between variables and differences between groups were analyzed using statistical tests. Results Of the articles 96 % were published in non-sensory-specific journals. Generic descriptive analysis (GDA) was used in two thirds of the articles. In more than half of the articles the number of assessors, or the time spent on assessor training, differed from what is recommended. An avarage of 1.4 descriptive words were used to name each attribute. In half of the articles no definitions of the attributes were given. In two thirds of the articles no reference products were presented to illustrate the attributes or different points of the scale. In three quarters of the articles the attributes were presentet in the section of method description, and not the results. The avarage share of nouns was 68.2 % and 31 % adjectives. A moderate negative correlation between the share of nouns and the time spent on panel training was significant. Conclusion Sometimes DSA is used without panel recommendations being followed. There are scientific articles where the sensory attributes are presented vaguely enough to question the usability of the results. To interperet naming of the sensory attributes as a qualitative results could motivate a more defined presentation, which would benefit the quantitative result (intensity assesment) by explaining what is meassured.

Behavioral Biases in Marketing: Conducting Choice Experiments with Inattentive Consumers and Modeling their DecisionsYegoryan, Narine 26 August 2020 (has links)
Eine zentrale Aufgabe des Marketings ist es, die Präferenzen von Konsumenten zu verstehen und die Heterogenität dieser aufzudecken. Eine Reihe kritischer Entscheidungen, z.B. bei der Neuproduktentwicklung, der Marktsegmentierung und dem Targeting oder der Preisgestaltung, beruhen auf der genauen Einschätzung der Konsumentenpräferenzen. Die Marketingliteratur hat sich bisher auf die Entwicklung von Modellen und Schätzverfahren konzentriert, die es ermöglichen, die Heterogenität von Konsumentenpräferenzen aufzudecken. Konsumenten unterscheiden sich jedoch auch in der Art und Weise, wie sie Kaufentscheidungen treffen und welche verfügbaren Informationen sie nutzen.
Das Ziel dieser Dissertation ist es, unser Verständnis für die Unaufmerksamkeit der Konsumenten gegenüber Produkteigenschaften bezüglich Entscheidungen zu verbessern. Es geht darum, 1) die Verbreitung einer solchen Unaufmerksamkeit in verschiedenen Kontexten zu untersuchen, 2) die Methoden, die ein solches Verhalten explizit berücksichtigen, zu untersuchen und zu erweitern, 3) potenzielle Verzerrungen in Parametern zu verstehen und 4) Implikationen für das Management abzuleiten.
Die Ergebnisse aus einer umfassenden Reihe von Anwendungen legen nahe, dass Konsumenten in verschiedenen Kontexten (z.B. Produktkategorien) und Settings (z.B. von hoher oder niedriger Komplexität) eine Menge an verfügbaren Informationen bezüglich Produkteigenschaften ignorieren. Zweitens, Entscheidungsmodelle, die ein solches Verhalten explizit berücksichtigen und zusätzlich weitere Daten wie z.B. Eye-Tracking nutzen, zu einem besseren In- und Out-of-Sample-Fit führen. Drittens führt die Missachtung eines solchen Verhaltens zu Verzerrungen, deren Richtung und Größe von der Art des Merkmals (d.h., ob eine bestimmte Richtung der Präferenzen erwartet werden kann) und dem Anteil der Konsumenten, die dieses Merkmal ignorieren, abhängt. Infolgedessen kann es dazu kommen, dass Manager keine optimalen Preis- und Targeting-Entscheidungen treffen. / A central task of marketing is understanding consumer preferences and uncovering consumer heterogeneity. A range of critical decisions, e.g., new product development, market segmentation and targeting, or pricing, rest upon accurate estimation of consumer preferences. Marketing literature has mainly focused on the development of models and estimation procedures that allow uncovering heterogeneity in consumer preference. However, consumers differ not only in their tastes but also in the way they make purchase decisions and the information they use.
The overall objective of this dissertation is to enhance our understanding of consumers' inattention to attributes when making choices. It aims to 1) examine the prevalence of such inattention across numerous contexts and settings, 2) investigate and extend the approaches that explicitly accommodate such behavior, 3) understand potential biases that may arise, and 4) demonstrate managerial implications when such behavior is neglected.
The findings from a broad set of applications suggest that consumers ignore a substantial amount of available attribute information across various contexts (e.g., product categories) and settings (e.g., of high or low complexity). Second, we establish that choice models explicitly accounting for such behavior and, additionally, leveraging supplementary data such as eye tracking, result in better in- and out-of-sample fit. Third, neglecting such behavior leads to significant biases, the direction and the magnitude of which depend on the type of the attribute (i.e., whether a particular direction of preferences can be expected) and the share of consumers ignoring this attribute. As a result, managers may make suboptimal pricing and targeting decisions.

Effects of attribute framing and goal framing on vaccination behavior: examination of message content and issue involvement on attitudes, intentions and information seekingHaydarov, Rustam January 1900 (has links)
Master of Science / Department of Journalism and Mass Communications / Joye C. Gordon / This experimental research adopts a typology of frames by Levin, Gaeth, and Schneider
(1998) and seeks to a) determine what combination of attribute and goal frames produces the strongest effect on vaccination behavior; b) ascertain to what extent personal relevance of vaccination moderates this framing effect; and c) explore how individual pre-existing characteristics, such as recent vaccination history, vaccine risk perception, vaccine dread, and
general attitude toward vaccination influence the persuasive power of framed messages.
The study, designed as field experiment 2 (+/- attribute frame) x 2 (+/- goal frame) x 2(involvement), recruited 476 adult female participants that were exposed online to four
experimental framing manipulations and a control condition. The main effect is consistent with the typology of frames — the combination of the positive attribute and the negative goal frame was the only condition that was significantly more persuasive than the control condition.
Participants who had children or were pregnant, for whom vaccination was more relevant and meaningful, have not reacted to message framing differently. However, general pre-existing attitudes towards vaccines, perception of vaccine safety, perception of vaccine efficacy, vaccine
dread, and vicarious experience with vaccine side effects, appear to be associated with
antecedents of vaccination behavior. Overall, this study has focused on ecological validity,aiming at the applicability of framing theory in the context of health communication.

Vad får dig att stanna? : En studie om varumärkeslojalitet hos konsumenter av livsmedelsprodukter i dagligvaruhandeln / What makes you stay? : A study of brand loyalty among consumers of food products in grocery storesDenckert, Emilia, Pankko, Linnéa January 2016 (has links)
Författare: Emilia Denckert och Linnéa Pankko Handledare: Universitetsadjunkt Åsa Lindström Examinator: Professor Bertil Hultén Fakultet: Ekonomihögskolan vid Linnéuniversitetet Program: Civilekonomprogrammet med inriktning marknadsföring Kurs: Examensarbete i marknadsföring för Civilekonomprogrammet 30 hp Examensarbetets titel: Vad får dig att stanna? Forskningsfråga: Vilka attribut ligger till grund för en varumärkeslojalitet hos konsumenter av livsmedelsprodukter i dagligvaruhandeln? Syfte: Syftet med detta examensarbete är att analysera och fastställa vilka attribut hos en produkt och ett varumärke som bidrar till att konsumenter bygger upp en lojalitet gentemot varumärket ifråga. Studien kommer att förklara vardera attribut, samt kombinationer av dessa, och klargöra huruvida de ligger till grund för konsumenters lojalitet till varumärken på livsmedelsprodukter som säljs i dagligvaruhandeln. Vidare ämnar studien uppfylla ett delsyfte, vilket är att ge implikationer till Smiling Group AB beträffande vilka attribut som genererar en varumärkeslojalitet. Resultatet av denna studie kommer därmed även att bistå med underlag till företags utvecklande av marknadsföringsstrategier som i sin tur kan påverka varumärkeslojaliteten positivt. Metod: Detta examensarbete har en deduktiv ansats. Vidare har kombinationer av kvantitativa och kvalitativa metoder använts. Insamlingen av studiens primärdata har tagit sig form dels som en enkätundersökning, och dels som djupintervjuer. Resultat och slutsats: Vi har konstaterat att kvalitet och pris är de attribut som till störst del ligger till grund för en varumärkeslojalitet hos konsumenter av livsmedelsprodukter i dagligvaruhandeln. Vidare har vi fastställt tre olika kombinationer av de fem attribut som ingått i studien samt vilken grupp av konsumenter som föredrar vilken kombination. Teoretiskt och praktiskt bidrag: Studiens teoretiska bidrag består dels av att vi identifierat några av de attribut vilka ligger till grund för en varumärkeslojalitet hos konsumenter av livsmedelsprodukter i dagligvaruhandeln. Vi har också tillfört konsumenters engagemang som en aspekt, vilken bör tas i beaktning när denna typ av varumärkeslojalitet studeras. Vi har praktiskt bidragit genom implikationer till Smiling Group AB om hur de bör förhålla sig till studiens fem attribut, och kombinationer av dessa, för att generera varumärkeslojala kunder. Detta bidrar även praktiskt till andra företag i branschen, då de kan använda studiens resultat och slutsats som underlag vid utformning av framtida marknadsföringsstrategier. Nyckelord: Varumärkeslojalitet, varumärke, lojalitet, attribut, konsumenter, dagligvaruhandeln, livsmedelsbranschen / Authors: Emilia Denckert and Linnéa Pankko Supervisor: Lecturer Åsa Lindström Examiner: Professor Bertil Hultén Faculty: School of Business and Economics at Linnaeus University Programme: Business Administration and Economics Programme Course: Degree Project in Marketing, The Business Administration and Economics Programme Title: What makes you stay? Research question: What attributes are the basis for brand loyalty among consumers of food products in grocery stores? Purpose: The purpose of this thesis is to analyze and determine the attributes of a product and a brand that helps consumers build up a loyalty to that brand. The study will explain each attribute, as well as combinations of these, and clarify whether they are the basis of consumers’ loyalty to brands of food products sold in grocery stores. Furthermore, the study intends to fulfill a subsidiary aim, which is to give implications to Smiling Group AB about what attributes that generates brand loyalty. The result of this study will thus also assist with data for corporate development of marketing strategies, which in turn can affect brand loyalty positively. Method: This thesis has a deductive approach. Furthermore, combinations of quantitative and qualitative methods have been used. The collection of the study's primary data has taken shape both as a survey, and as in-depth interviews. Results and conclusions: We have stated that the quality and price are the attributes that to the greatest part is the basis for brand loyalty among consumers of food products in grocery stores. Furthermore, we have established three combinations of the five attributes that are included in the study and what groups of consumers who prefer which combination. Theoretical and practical contributions: The theoretical contribution partly consists of identification of some of the attributes which form the basis of a brand loyalty among consumers of food products in grocery stores. We have also added consumer engagement as an aspect which should be taken into consideration when this type of brand loyalty is studied. We have practically contributed by implications to Smiling Group AB about how they should relate to the study’s five attributes, and combinations thereof, to generate brand loyalty. This also contributes practically to other companies in the industry, since they can use the study's findings and conclusions as a basis for the design of future marketing strategies. Key words: Brand loyalty, brand, loyalty, attribute, consumers, grocery store, food industry

Värdering av kriterier vid stora investeringar : En jämförelse mellan olika intressenters uppskattningar av kriterierSamstad, Anna January 2016 (has links)
In what way does different stakeholders assess a decision and its consequences, and how do these assessments differ? When a company stands before a big decision, they need to consider aspects that are economic, ecologic and social. To make a good decision they need to consider the society and its different stakeholder groups. This study examined how different groups values and weights different criteria. The study has been done with the project Sundsvall logistics park as a case, with criteria related to that project. The goal of the study was to find a way to value and weight different criteria and then compare how the company and the stakeholders assesses these criteria. This has been done through interviews with relevant people that has got extra knowledge about the project Sundsvall logistics park, and through a survey that has been sent out to residents of Sundsvall. The informants and respondents got to assess values and weights to the criteria relative to an indirect alternative where the logistics park isn’t built. The data was then compiled using multi attribute utility theory as a tool to present the comparison. The result of the study suggests that the differences between the valuations and weightings of the criteria is partly due to an uncertainty in how the logistics park would affect the criteria, but that the biggest reason probably depends on what perspective the person is viewing the logistics park from. If the person is viewing the logistics park from an industrial perspective, the criteria related to industrial development is getting more important and is going to take up more room in the analysis. If the person is viewing the logistics park from an individual and social perspective, the criteria related to that is more important and takes up more room in the analysis. / På vilket sätt uppskattar olika intressenter ett beslut och dess konsekvenser, och hur skiljer sig dessa uppskattningar åt? När företag idag står inför stora beslut behöver de ta hänsyn till aspekter som är både ekonomiska, ekologiska och sociala. För att beslutet ska bli bra behöver de ta hänsyn till samhället och dess olika intressentgrupper. Denna studie är en undersökning av hur olika grupper värderar och viktar olika kriterier. Studien har utförts mot projektet Sundsvall Logistikpark med kriterier relaterade till projektet. Målet med studien har varit att hitta ett sätt att värdera och vikta olika kriterier för att sedan göra en jämförelse av hur företaget och intressenterna uppskattar dessa kriterier. För att göra detta har intervjuer utförts med personer som är extra insatta i projektet med Sundsvall logistikpark och en enkät skickats ut till boende i Sundsvall. Informanterna och respondenterna har fått uppskatta värden och vikter på kriterierna utifrån ett indirekt alternativ där logistikparken inte byggs. Datan har sedan sammanställts genom att använda multiattributsnyttoteori som verktyg för att presentera jämförelsen. Resultatet av undersökningen tyder på att de skillnader som finns i värderingar och viktningar av kriterierna dels beror på en viss osäkerhet angående hur logistikparken skulle kunna påverka de olika kriterierna och hur ett värde kan uppskattas på dessa, men att den största orsaken troligen beror på vilket perspektiv personen ser logistikparken på. Om personen ser på logistikparken från ett industriellt perspektiv blir kriterier som har med industriell utveckling att göra viktigare och tar större plats i analysen. Om personen ser på logistikparken från ett individuellt och socialt perspektiv blir sådana kriterier viktigare och tar större plats i analysen

產品屬性與消費者產品知識對購買意願之影響-以液晶電視為例羅珮仁, Lo, Pei Jen Unknown Date (has links)
液晶電視在市場上已逐漸蔚為主流且具有廣大發展潛力,而目前台灣液晶電視市場呈現家電與資訊品牌共逐商機的局面。然而其擁有的技術背景與資源亦有所不同,如何能投消費者所好,擬定出有效的行銷策略,值得進一步探討。本研究之目的在探討消費者產品知識高低對產品內外在屬性訊號與購買意願的影響,進而分析不同市場區隔的消費者特色,瞭解其對產品屬性之偏好與差異,提供業者制定行銷策略上的建議,協助其進行有效的目標行銷。本研究採用聯合分析法,先利用前測設計消費者產品知識的量表,正式問卷受測體則採用整體輪廓法的短文描述進行測試。共收回有效問卷152份。研究發現:
1. 總體受測者屬性偏好依序為:畫面品質>保固期限>價格>反應時間>售後服務>品牌背景。
2. 本研究根據消費者知識高低將消費者做「事前區隔」分群,發現知識低的群體較重視產品外在屬性線索,而知識高的群體較重視產品內在線索。建議液晶電視廠商應善加利用「客製化」的概念,依照不同類型的消費者所重視之價值做為產品的定位或訴求。
3. 以對產品屬性的成分效用值做「事後區隔」分群,發現整體消費者可分為兩群:集群一重視產品實際功能表現、願意付出高價;集群二則重視較長保固期限、追求低價,提供廠商在設計產品屬性組合的參考。
4. 與人口統計變數交叉分析之後,獲得各區隔族群對液晶電視產品屬性偏好之相關數據。例如女性對價格、保固的重視程度較男性為高;理工背景消費者對產品內在屬性要求較文法商背景消費者為高等。

USING MAVT TO INCORPORATE PUBLIC PERCEPTION WHEN CHOOSING A NUCLEAR FUEL CYCLEClement, Stephen 01 January 2016 (has links)
Nuclear energy is a source of carbon free power. With many countries striving to make deep carbon cuts in their energy sectors, nuclear energy could be a large part of the solution. One of the main obstacles standing in the way of the use of nuclear energy is the issue of used nuclear fuel disposal. According to the NEI, the U.S. creates about 2000 metric tons of used nuclear fuel per year and has generated around 76,000 metric tons of used nuclear fuel over the last 4 decades. While there are technical problems that need to be solved, it is primarily the public and political opposition to the disposal of used nuclear fuel that stands in the way of progress in this area. This work addresses this issue through Multi-Criteria Decision Analysis (MCDA). To make a decision among ten different fuel cycles, we have brought together five stakeholders: Nuclear Scientists and Engineers, Environmental Scientists, Economists, Political Scientists, and The General Public. Using Multi-Attribute Value Theory (MAVT), we have been able to develop decision models for each stakeholder as well as a model that combines them all and came to the conclusion that of the ten fuel cycles considered, the best decision is to continue to use On Site Dry Cask Storage. This decision is made with small sample sizes but the methodology could be applied at much larger scales and can potentially be used to choose a fuel cycle that encounters much less political and social opposition to its implementation.

Display of Multi-Attribute Data Using a Presentation Description LanguageKemble, Jonathan 08 November 1999 (has links)
"In order to make large applications that manage multi-attribute data usable, they must have an effective user interface. Application data and data relationships must be displayed in a manner that is useful for a particular user while still following principles of user interface design. A User Interface Management System (UIMS) is an application independent data presentation system which isolates the interface portion of the application and can allow a high level of customization. A presentation description language can be used to control the UIMS and allow maximum flexibility. This thesis investigates a UIMS controlled by a language that allows a user to easily describe the application data and data relationships at a high level of abstraction. The UIMS uses this language to structure application data and augment it with properties. A rule-based system then uses the augmented data along with graphical design knowledge to determine the content, layout and details of the interface used to display the data. Finally, a graphical interface is generated to present the data. A system to provide this functionality was designed and implemented. Experiences with the system showed this approach to be valid and provided ideas for future work. "

Uma abordagem escalável para controle de acesso muitos para muitos em redes centradas de informaçãoSilva, Rafael Hansen da January 2016 (has links)
Um dos principais desafios em Redes Centradas em Informação (ICN) é como prover controle de acesso à publicação e recuperação de conteúdos. Apesar das potencialidades, as soluções existentes, geralmente, consideram um único usuário agindo como publicador. Ao lidar com múltiplos publicadores, elas podem levar a uma explosão combinatória de chaves criptográficas. As soluções projetadas visando a múltiplos publicadores, por sua vez, dependem de arquiteturas de redes específicas e/ou de mudanças nessas para operar. Nesta dissertação é proposta uma solução, apoiada em criptografia baseada em atributos, para controle de acesso a conteúdos. Nessa solução, o modelo de segurança é voltado a grupos de compartilhamento seguro, nos quais todos os usuários membros podem publicar e consumir conteúdos. Diferente de trabalhos anteriores, a solução proposta mantém o número de chaves proporcional ao de membros nos grupos e pode ser empregada em qualquer arquitetura ICN de forma gradual. A proposta é avaliada quanto ao custo de operação, à quantidade de chaves necessárias e à eficiência na disseminação de conteúdos. Em comparação às soluções existentes, ela oferece maior flexibilidade no controle de acesso, sem aumentar a complexidade do gerenciamento de chaves e sem causar sobrecustos significativos à rede. / One of the main challenges in Information-Centric Networking (ICN) is providing access control to content publication and retrieval. In spite of the potentialities, existing solutions often consider a single user acting as publisher. When dealing with multiple publishers, they may lead to a combinatorial explosion of cryptographic keys. Those solutions that focus on multiple publishers, on the other hand, rely on specific network architectures and/or changes to operate. In this dissertation, it is proposed a solution, supported by attribute-based encryption, for content access control. In this solution, the security model is focused on secure content distribution groups, in which any member user can publish to and retrieve from. Unlike previous work, the proposed solution keeps the number of cryptographic keys proportional to the number of group members, and may even be adopted gradually in any ICN architecture. The proposed solution is evaluated with respect to the overhead it imposes, number of required keys, and efficiency in the content dissemination. In contrast to existing solutions, it offers higher access control flexibility, without increasing key management process complexity and without causing significant network overhead.
