The buying decision process describes how the consumer makes a purchase decision through a rational process (Markin, 1979) and an understanding for how consumers make a purchase decision can according to Sands et al. (2010) be obtained by increased knowledge for the information search process (the second part of the buying decision process) before a purchase. Today’s society offers great opportunity to obtain information (Rahim & Clemens, 2012; Bawden & Robinson, 2009) and by that there are in other words good opportunities for a rational acting by the consumers. However, there are factors working against that consumers act rationally and seek information prior to their purchases primarily in the form of the concept of information overload (Bawden & Robinson, 2009) which claims that consumers are limited in their information search because there is too much information but also other factors such as lack of time (Wood & Neal, 2009) and ability to find information (Slegers et al. 2012) are believed to affect the information search process. The purpose of this essay is to describe the information search behavior of consumers prior to a purchase considering irrational purchase decisions or the possibility of rational purchase decisions linked to product category and age because these variables are assumed to have an impact on the information search behavior prior to a purchase (Nelson, 1970; Phillips & Sternthal, 1977; Sledgers et al., 2012). The method applied in this essay is structured interviews conducted in a shopping center in the central parts of Örebro and the participating respondents are consumers who just made a purchase. The results of the study indicate that the majority of the consumers are making irrational purchase decisions and that they therefore do not use the opportunity to act rationally, although today’s society provide good opportunities. The information search behavior doesn’t seem to depend on product category except that the information sources used differ among categories. The result also shows that younger consumers search more information in comparison with older consumers. Another finding is that neither ability to find information, lack of time or information overload seem to be reasons for that the majority of the consumers have not searched for information and nor do it seem to be the reason for why the consumers that do search for information stop to search. That they are not seeking seems instead to be because they feel that they know enough about the kind of product they have bought and the main reason that those who search stop to search is that they feel that they have found enough information to make a purchase decision. Key words: Consumer behavior, purchase decisions, the buying decision process, information search, rationality, irrationality, search goods, experience goods, information overload

Thesis (MA)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: We are living in an increasingly global and connected society with information creation increasing at exponential rates. The research sets out to help solve the problem of mitigating the effects of information overload in order to increase the novelty of our interactions in the digital age. Online social-networks and microblogging services allow people across the world to take part in a public conversation. These tools have inherent constraints on how much communication can feasibly occur. Become too connected and a user will receive too much information to reasonably process. On Twitter (a microblogging service), lists are a tool for users to create separate feeds. The research determines whether lists are an effective tool for coping with information overload (abundance of updates). Using models of sustainable online discourse and information overload on computer-mediated communication tools, the research found that lists are an effective tool to cope with information overload on microblogging services. Quantitatively, individuals who make use of lists follow more users and when they start using lists they increase the amount of information resources (following other users) at a greater rate than those who do not use lists. Qualitatively, the research also provides insight into the reasons why people use lists. The research adds new academic relevance to ‘information overload’ and ‘online sustainability’ models previously not used in the context of feed-based online CMC tools, and deepens the understanding and importance of usercurated filtering as a way to reap the benefits from the increasing abundance of information in the digital age. / AFRIKAANSE OPSOMMING: Ons leef in ’n toenemend globale en gekonnekteerde samelewing waarin inligtingskepping toeneem teen ’n eksponensiële koers. Hierdie navorsing het ten doel om die newe-effekte van die oorvloed van inligting te verlig sodat daar meer waarde uit ons interaksies in die digitale era kan geput kan word. Aanlyn sosiale-netwerke en mikroblog-dienste laat mense wêreldwyd toe om deel te neem in ’n openbare gesprek. Hierdie aanlyn gereedskap het egter inherente beperkinge op hoeveel kommunikasie prakties moontlik is. Wanneer gebruikers té gekonnekteer raak, word daar te veel ingligting ontvang om redelikerwys verwerk te kan word. Op Twitter (’n mikroblog-diens) is lyste ’n hulpmiddel waarmee gebruikers afsonderlike strome van inligting kan skep. Deur die gebruik van modelle van ‘volhoubare aanlyn diskoers’ en ‘inligtingoorlading’, bewys hierdie navorsing dat lyste ’n doeltreffende hulpmiddel is om die oorvloed van inligting te verlig op mikroblog-dienste. Kwantitatief volg gebruikers wat lyste gebruik meer gebruikers vergeleke met die wat nie lyste gebruik nie. Wanner hul lyste begin gebruik, volg hulle gebruikers teen ’n hoër koers as dié wat nie lyste gebruik nie. Kwalitatief bied die navorsing ook insig oor die redes vir die gebruik van lyste. Die navorsing onderstreep die akademiese relevansie van ‘inligtingoorlading’ en ‘aanlyn volhoubaarheid’ modelle wat nie voorheen gebruik is in die konteks van stroom-gebaseerde aanlyn gereedskap nie, en verdiep die begrip en belangrikheid van gebruiker-saamgestelde filtrering as ’n manier om die voordele te trek uit die toenemende oorvloed van inligting in die digitale era.

abstract: This thesis describes research into the application of socially reflective, or "Slow", design principles to modern mediated systems, or "Fast" technology. The "information overload" caused by drastic changes in the nature of human communications in the last decade has become a serious problem, with many human-technology interactions creating mental confusion, personal discomfort and a sense of disconnection. Slow design principles aim to help create interactions that avoid these problems by increasing interaction richness, encouraging engagement with local communities, and promoting personal and communal reflection. Three major functional mediated systems were constructed to examine the application of Slow principles on multiple scales: KiteViz, Taskville and Your ____ Here. Each system was designed based on a survey of current research within the field and previous research results. KiteViz is a visually metaphorical display of Twitter activity within a small group, Taskville is a workplace game designed to support collaboration and group awareness in an enterprise, and Your ____ Here is a physical-digital projection system that augments built architecture with user-submitted content to promote discussion and reflection. Each system was tested with multiple users and user groups, the systems were evaluated for their effectiveness in supporting each of the tenets of Slow design, and the results were collected into a set of key findings. Each system was considered generally effective, with specific strengths varying. The thesis concludes with a framework of five major principles to be used in the design of modern, highly-mediated systems that still apply Slow design principles: design for fundamental understanding, handle complexity gracefully, Slow is a process of evolution and revelation, leverage groups and personal connections to encode value, and allow for participation across a widely distributed range of scales. / Dissertation/Thesis / M.S.D.

Vilken effekt frivilligt redovisad information har på kapitalmarknaden är en omstridd fråga i litteraturen. Vissa menar att mer information minskar informationsasymmetrin på kapitalmarknaden medan andra finner motsatt resultat, där en förklaring är information overload. Denna studie bidrar till frågan genom att studera rapportlängden samt informationsinnehållet i kvartalsrapporter från 155 bolag noterade på Nasdaq Stockholm under åren 2015-2016, där bid-ask spread och handelsvolym används som mått på informationsasymmetri. Av fyra genomförda regressionsanalyser visar två signifikanta resultat. De signifikanta resultaten visar att frivilligt redovisad information höjer handelsvolymen, vilket indikerar att informationsasymmetrin på kapitalmarknaden minskar. Detta resultat har betydelse för såväl företag som standardsättare såsom IASB eftersom det tyder på att den svenska marknaden efterfrågar mer redovisad information.

Purpose: The purpose of this study was to explain whether the conceptualized model of consumer confusion regarding the multiple number of brands and products also applies to the increasing number of eco-labels. The study also examined how the attitudes were affected if confusion occurred amongst the consumers. More specifically, whether consumer confusion leads to negative attitudes. Theoretical Framework: The conceptualized model of consumer confusion, including the three dimensions of ambiguity, information overload and similarity was used in this research.In addition, theories regarding attitudes and indicators that affect consumer’s attitudes werepresented and used for the analysis. Methodological Framework: This research took an explanatory and deductive approach. The research was carried out with a quantitative method including three hypotheses derived from the literature. Data was collected through a questionnaire that was spread online on social media. The gathered data was coded accordingly in order to get the results from the frequencies, descriptive statistics, correlation and the regression analysis. Empirical Results: It was discovered that the respondents were confused by eco-labels and eco-labelled products regarding all the three dimensions of the conceptualized model of consumer confusion. However, the fact that the attitudes towards eco-labels and eco-labelled products were very positive, led to a rejection of all the three hypotheses. Consequently, supportive questions from the questionnaire and the demographic details of the sample served as additional support to further discuss the results of the study. Conclusions: This study showed that the conceptualized model of consumer confusion also applies to eco-labels. However, the consumers still had positive attitudes towards eco-labels and eco-labelled products which could be seen as contradictory. Nevertheless, positive beliefs about eco-labels and its effects and demographic details were found to have an impact on the positive attitudes.

Context. Information overload is an increasingly important problem of our age where the amount of data we have is expanding drastically with the use of digital communication. Information retrieval models are developed to help overcoming this problem with computerized tools. Semantic information retrieval, which means retrieving information based on the interpretations of meanings of the words, is one of these models and started to be used commonly to handle large amount of data in the Internet and in enterprises to overcome information overload problems. Objectives. In this study we investigate different information retrieval models for using with knowledge management systems in large-scale organizations from the perspective of software engineers. To this end, we aim at identifying existing issues and needs about information overload and then assessing different solutions against these needs. Afterwards, we analyze the chosen solution, which is semantic search, and define and carry out an implementation process to reflect on it. Finally, the usefulness and feasibility of this type of solutions to overcome the specified information overload problems in software engineering is studied and discussed. Methods. We performed a literature review to extract the existing knowledge, technology, and the problems and solutions in the defined context. Then a case study was conducted at a development site of Ericsson AB in Sweden. Case study involved unstructured and semi-structured interviews for data collection, and an implementation attempt for a simple semantic knowledge management system. Thematic Coding Analysis method is used for qualitative data analysis. Results. We identified 23 codes that are categorized under 8 themes from the opinions of company practitioners about semantic knowledge management systems. They are mainly about the existing problems, arguments for using semantic system for solving them, and suggestions and challenges. Conclusions. We conclude that semantic knowledge management systems have a very high potential to solve information overload problems in software engineering if the necessary measures are taken. We found that the problems are related to search engine and the document structure of the tools; usefulness of semantic system is the capability of ontology based retrieval to filter out irrelevant documents and extract hidden data and people’s skills and interests; and finally the challenge is the necessary endeavor to elicit and satisfy all the needs.

Information and communication technology (ICT) had a huge impact on the healthcare services and the Internet plays an important role in forming patients’ attitudes towards health related services. Although the Internet mentioned as one of the major contributors in todays’ Information Overload (IO), common notion is that healthcare sector has been remained immune of IO effects. Throughout an action research, this study showed that IO has significant impact on treatment sessions of patients suffering from chronicle mental disorders in two ways. Firstly, patients’ acquired information from the Internet bombards physician in the treatment sessions, which eventually slows down the treatment process. Secondly, protocols and administrative procedures are subject to change, which leads to frustrating relearning cycles due to the huge amount of information attaching to them. Also, physicians have a tendency to keep themselves updated about new achievements in their field, which adds to the IO problem. In an attempt to enhance the situation an application model purposed in the second half of this research, which uses social web as a platform to provide a service based on Information Logistics (IL) principles to deal with the problem of IO.

Att uppnå situationsmedvetenhet kan helt avgöra ifall en person klarar av att lösa en specifik uppgift eller inte. Dagens ledningssystem har ofta som uppgift att stödja användaren att upp nå situationsmedvetenhet och därmed klara av att lösa sina uppgifter. Detta examensarbete syftar till att undersöka vilka potentiella brister det kan tänkas finnas inom de militära och civila ledningssystemen. Att lista dessa problem är av intresse då det är av stor vikt att kunna se hur dessa system skulle kunna tänkas förbättras. Både utvecklare och användare har intervjuats i syfte att samla in viktiga åsikter. Resultatet blev en lista där de största problemen redovisades samt vilken inverkan de kan tänkas ha på användaren och dennes arbetsuppgifter.

Information overload förekommer på alla arbetsplatser där informationsbearbetning är viktigt för arbetsprocesserna. I vissa fall kan information overload medföra allvarliga konsekvenser både för den enskilda medarbetaren och för verksamheten i stort. På akutmottagningen på Centrallasarettet i Växjö har sjuksköterskorna en viktig roll som samordnare av den information som används i patientarbetet. Syftet med denna undersökning är att undersöka vilka faktorer som främst orsakar information overload hos sjuksköterskorna på akutmottagningen CLV, samt att undersöka hur fenomenet IO påverkar vårdkvaliteten. Under mars och april 2007 genomfördes intervjuer med sju sjuksköterskor på den aktuella akutmottagningen utifrån en frågemall som utformats med hjälp av aktuell forskning på information overload. Resultatanalysen skedde utifrån en specifik orsakstabell som tagits från en litteratursammanställning av Eppler och Mengis (2004). Orsakstabellen utgår ifrån fem specifika områden - personliga faktorer, informationens karaktär, arbetsuppgifter och processparametrar, organisatorisk design samt informationsteknologi. Studien har genomförts utifrån en kvalitativ ansats. Undersökningen visar att sjuksköterskorna på akutmottagningen ofta drabbas av information overload, och att riskfaktorer finns i samtliga fem ovanstående kategorier. Flera av deltagarna upplever regelbundet information overload-relaterade symtom och detta riskerar att hota patientsäkerheten på mottagningen. Dessutom leder det till minskad arbetstillfredsställelse hos sjuksköterskorna. Slutligen konstateras att en ordentlig informationsplan behöver upprättas för att rätta till de missförhållanden som orsakar information overload. Det är framför allt viktigt att informationen är relevant och hanterbar för att höja patientsäkerheten och vårdkvaliteten. / Information overload exists in all organisations where information processing is important for the work process. In some cases information overload is a serious threat to both the individual who suffers from it and to the organisation at large. At the emergency department at the Central Hospital in Växjö the nurses have an important function as coordinators of the information used in the patient treatments. The purpose of this study is to find out which factors primarily cause information overload in the emergency department and what implication this has on the quality of care given there. In March and April of 2007 seven nurses were interviewed on the subject of information overload. Through a literary review relevant questions were formed for the interviews. The analysis of the answers were conducted from a table by Eppler and Mengis (2004) illustrating the causes of information overload. The table has five sub categories, personal factors, information characteristics, task and process parameters, organizational design and information technology. The study has a qualitative approach. The result shows that the nurses at the ED are often affected by information overload, and that risk factors exist in all five sub categories mentioned above. Several nurses regularly experience symptoms caused by information overload, and this is a threat to patient safety at the ED. It also causes dissatisfaction in the daily work. Finally we conclude that a proper information plan is needed in order to find solutions to the problem. The information needs to be relevant and manageable to increase patient safety and the quality of care.
