Strategic decision makers typically use a wide range of communication and information media in complex, uncertain and often ambiguous or politically charged organizational contexts. However, little help is available in ensuring that their information behaviour is efficient and effective. This study evaluates the use of information systems (IS) as communication media in strategic decision-making processes (SDMPs), focusing on strategic information processing, and how context affects its performance. The analysed strategic decisions (n = 113) were taken in the time period between 2000 and 2008 in large Western organisations. The aim of this investigation was to look at the link between the use of IS during the decision-making process and the performance of the SDMP, taking into account internal and external contextual factors. Using existing information processing theory and research on the SDMP as a theoretical basis, hypotheses were developed and environmental contingencies and political information behaviour were selected as moderating effects on the relationship of IS use and the performance of strategic decisions. A survey and complementary semi-structured interviews were conducted, which studied particular strategic decisions through quantitative and qualitative methods. Results provide support for a number of the study¿s hypotheses; however, several interesting findings regarding contextual factors, such as information anarchy and environmental munificence/hostility, do not support the hypotheses. Implications for theory and practice concerning information behaviour and its context are discussed.

This paper investigates the patterns of informal scholarly communication on social media as they manifest themselves among scholars at Umeå University. A survey was sent out to the university’s scholars, from PhD students all the way through to professors, and received 747answers from a total of 2646 requests. The survey gathered background data, data on how scholars build and maintain their academic networks via social media, and data on scholars’ use of social media for seeking information. The data thus gathered was interpreted through a comparative analysis. The main hypothesis was that, following the work of Tony Becher and Paul R. Trowler, the various faculties of the university would constitute distinguishable ”tribes” with their own customs regarding using social media for academic purposes. The data was furthermore analysed looking for patterns of use by gender, by academic position, and by the firmness of that position – or, putting it more plainly, job security. The analysis revealed that in terms of networking, the relevant variables were those of gender and academic position, with women being more avid social media networkers than men, and more junior scholars more avid than their seniors. However, in terms of the actual social networks used, there was a distinct tendency for humanist scholars to use Facebook which set them apart from the other three faculties. In terms of information seeking, there was again a finding of the more junior scholars leading the way, but also a clear indication of differences rooted in faculties. The humanist scholars were found to be by some distance more inclined to both seek information on social media, and to help others seeking it on social media, compared to the other faculties. The medical scholars, by contrast, were also by some distance the least inclined to both seeking and helping. As above, the humanists had a marked preference for using Facebook when seeking information through social media.

Thesis (MPhil)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: Health information-seeking is a complex and dynamic construct. This study attempted to quantify and explain the use of interpersonal communication, media and related technologies as health information sources among first year university students on the campus of Stellenbosch University (SU), using a cross-sectional survey design. The questionnaire and web-based survey intended to measure and document important research constructs at a single point in time. Data from this survey provide exploratory information on patterns of health information-seeking practices and preferences encountered among the research target group. Measures of the reasons for health information-seeking on specific topics; health information sources/channels and frequency of source/channel use; information source credibility and quality as well as the outcomes of the health information-seeking process were used as secondary research aims in this study. Health communication and health management needs of the research population were also important research variables to establish. Results from this research indicate that the health status of the study cohort was good. The mean of the BMI kg/m² for the current study cohort lies at the higher end of the BMI kg/m² continuum for this age group, which indicates that the lifestyle of the study cohort is at risk. The use of health information sources among the research cohort was diverse. This research confirms that interpersonal communication is an important information medium through which young adults receive health information. The concept of an ecological context to health communication and its effects are therefore supported by these results. Use of media sources and related technology was common and diverse among the study cohort, mirroring patterns of media use for other young adult groups. Results further support the theory of effect-studies in communication (the media), where the provision of certain types of information through the media, indicate to have an impact on people’s thinking and behaviour. A behaviour change as result of the health information-seeking process was reported among the research cohort. Health communication literature refers to small numbers of studies conducted on health information-seeking among young adults (student populations). The current research has attempted to add to the body of knowledge on health information-seeking and its outcomes among a student population group in a South African university setting. / AFRIKAANSE OPSOMMING: Die soektog na gesondheidsinligting is 'n dinamiese en komplekse proses. Hierdie navorsing het gepoog om die gebruik van interpersoonlike kommunikasie, media en verwante tegnologieë as inligtingsbronne oor gesondheid onder eerstejaar-studente op die kampus van die Universiteit van Stellenbosch (US) te kwantifiseer en te verklaar. 'n Dwarsdeursnitopname is as studieontwerp gebruik. Die web-gebaseerde vraelys het gepoog om belangrike navorsingskonstrukte tydens 'n enkele tydgleuf te probeer meet. Data van hierdie opname verskaf verkennende inligting oor die patrone van die soeke na gesondheidsinligting en gesondheidsinligtingvoorkeure van studente. Redes vir die soek na gesondheidsinligting; mediums/metodes waardeur inligting verkry word; frekwensie van soektogte; geloofwaardigheid van mediums en die kwaliteit daarvan; onderwerpe waarna gesoek word en die uitkomste van hierdie gesondheidsinligtingsoektog, is as sekondêre navorsingsuitkomste van belang geag. Gesondheidskommunikasiebehoeftes onder die navorsingsteikengroep was belangrik om vas te stel. Resultate van die navorsing dui aan dat die gesondheidstatus van die navorsingsgroep goed was. Die gemiddelde BMI kg/m² vir die groep was egter aan die bokant van die BMI kg/m² kontinuum vir die ouderdomsgroep en dui op moontlike leefstylrisiko’s vir die groep. Die gebruik van gesondheidsinligtingsbronne was baie divers. Hierdie navorsing ondersteun die feit dat interpersoonlike kommunikasie, as gesondheidsinligtingsbron, nog 'n belangrike rol speel onder jong volwassenes. Die konsep van 'n ekologiese konteks vir gesondheidskommunikasie en die uitwerking daarvan, word ondersteun deur die huidige navorsingsresultate. Die gebruik van media en verwante tegnologieë, as inligtingsbronne vir gesondheid, is as baie divers gerapporteer. Dit bevestig patrone van mediagebruik wat onder ander jong volwassenes gevind is. Resultate van hierdie navorsing ondersteun ook die teorie van effek-studies in kommunikasie (die media), waar die verskaffing van inligting deur die media 'n impak op mense se denke en gedrag aandui. 'n Gedragsverandering is wel deur die navorsingsgroep aangedui as resultaat van die soeke na gesondheidsinligting. Gesondheidskommunikasieliteratuur verwys na enkele studies wat oor gesondheidsinligtingsoektogte onder jong volwassenes (studente-populasies) gedoen is. Die huidige navorsing het gepoog om 'n bydrae te maak tot hierdie kennis en die uitkomste daarvan onder studente op 'n Suid-Afrikaanse universiteitskampus.

This research reported in this thesis explores job search networking amongst 16-24 year olds living in Scotland, and the role of social media platforms (i.e. Facebook, Twitter, and LinkedIn) during this process. Networking is treated as an information behaviour; reflecting this, the study is underpinned by a prominent model from the domain of information science. A sequential, mixed methods approach was applied to gather data. This included the use of interviews, focus groups, and a survey questionnaire. The interviews incorporated ego-centric network methods to develop a relational perspective of job search networking. The findings show that young people accrue different types of information from network contacts which can be useful for all job search tasks. Indeed, frequent networking offline and on social media is associated with positive job search outcomes. This is especially true of engaging with family members and acquaintances, and frequent use of Facebook for job search purposes. However, demographic and other contextual factors have a substantial impact on the nature of networking behaviours, and the extent to which they can influence outcomes. Additionally, young jobseekers face a range of barriers to networking, do not always utilise their networks thoroughly, and are more likely to use social media platforms as supplementary tools for job search. A key contribution of this work is that it provides a detailed insight into the process of networking that has been neglected in previous studies. Its focus on social media also reveals a new dimension to the concept which has received little attention in the job search literature. Given its focus on young jobseekers living in Scotland, the findings have also been used to create a detailed list of recommendations for practitioners.

The provision of accessible and usable health information is vital for making informed health decisions and embracing active and preventative health behaviours (such as reporting of symptoms, early screening and seeking medical help). Previous research in this area has focused on health-related information seeking behaviour and use of information by citizens of developed countries and within urban geographical locations. The common thread from existing research within the context of developing countries, particularly in Africa, is the need for health information to be provided in a way that considers the diverse cultural perspectives and characteristics of rural communities; regarding both the content and the design of health information services. Considering the cultural aspects is important. However, there is little or no work that has considered the provision of health information that is culturally and locally appropriate. This research aims to investigate the health information behaviour of men in rural Nigeria and explore the local sociocultural aspects that relate to the provision of prostate cancer information. The research extends the theoretical framework of Johnson’s Comprehensive Information Seeking model to include health-related information design heuristics that address aspects of cultural appropriateness within rural contexts and particularly within the setting of developing countries. A qualitative approach was adopted as it was considered appropriate for this research. The research utilised 35 semi-structured interviews and 5 focus group discussions with men (aged 35 or over) residing in rural areas of Nigeria. Participants shared their experiences with health-related information seeking and use, the barriers they encounter and the role that culture and rurality play in that process. Findings show that within rural Nigeria, culture and religion play a vital role in shaping the health information behaviour of men. There is a lack of knowledge about important health issues that affect men, such as prostate cancer. The study documents that internal, interpersonal sources and oral-based communication methods are preferred in rural communities. Based on the findings, a revised model of health information behaviour that extends the existing scholarly perspectives to include cultural context and information use component in rural communities in Nigeria was presented.

<div>Information security practitioners and researchers who possess sufficient depth of conceptual understanding to reconstitute systems after attacks or adapt information security concepts to novel situations are in short supply. Education of new information security professionals with sufficient conceptual depth is one method by which this shortage can be reduced. This study reports research that instructed two groups of ten undergraduate, pre-cryptography students majoring in Computer Science in cryptography concepts using representational understanding first and representational fluency first instructional treatment methods. This study compared learning results between the treatment groups using traditional paper-based measures of cognitions and fMRI scans of brain activity during cryptography problem solving. Analysis found no statistical difference in measures of cognitions or in cognitive processing, but did build a statistical model describing the relationships between explanatory variables and cryptography learning, and found common areas of cognitive processing of cryptography among the study’s twenty subjects.</div>

Internet har gett konsumenten en ökad marknadsöverblick, detta har gjort det möjligt för konsumenten att tidseffektivt jämföra varor och priser. Detta innebär att dagens konsument är betydligt mer välinformerad. Medvetenheten om en stor och komplex marknad innebär ett högt engagemang och upplevda risker med köpet som följd. Det höga engagemanget innebär att man som konsument bland annat söker information för att reducera sina upplevda risker. Syftet med denna uppsats är att minska luckan i teorin om konsumenters riskreducerande informationsbeteende då de genomgår köpprocessen i ett högengagemangsköp. Ett annat syfte blir att se vilka faktorer kring informationssökning som är viktiga i ett högengagemangsköp på en högteknologisk marknad 2006. Frågeställningarna rör hur informationskällorna används idag, vilka källor som har störst utvecklingspotential och hur denna utveckling borde se ut. Datainsamlingen har skett genom åtta stycken djupintervjuer med studenter från olika fackhögskolor inom Högskolan i Jönköping. Studenternas köp av bärbar dator de senaste sex månaderna har fungerat som underlag för samtalet. Resultatet av studien visar att de ekonomiska och funktionella riskerna upplevts vara mycket omfattande för våra respondenter. Priset och krav på en viss funktionalitet har varit klart tidigt i köpprocessen, funktionalitetskravet har under köpets gång översatts från behovsbeskrivningar till teknisk specifikation. Översättningen har mestadels inneburit omfattande informationssökning på Internet, vilket i många fall inneburit att respondenten engagerat personliga källor för värdering av informationen. De ekonomiska och funktionella riskerna har varit aktuella växelvis under köpprocessens olika faser. Många upplevelser kring informationssökningen präglas av ineffektivitet. Det icke kommersiella intryck information från jämförelsesajter på nätet och personliga källor ger ser vi ha en stor potential att kunna utvecklas. Detta genom att både i butik och på Internet aktivt arbeta med konsumenternas referenspunkter. Lösningsorienterad information med fokus på att bygga relationer och förtroende har enligt studiens resultat utvecklingsmöjligheter både på Internet och bland säljare. / Today Internet has given consumers a greater possibility to have a more complete view over the range of products on a market. This has made it possible to in a time effective way compare products and prices. A greater amount of perceived risks when purchasing a high involvement product is one result of the consumers awareness of a large and complex market. To reduce the risks, that high involvement purchase in hazes, the consumer is in a greater need of information The purpose with this essay is to reduce the gap in the theory about consumers risk reducing information behaviour when following the buyer’s decision process in a high involvement purchase. Another purpose is to identify which factors that is important when seeking information during a high involvement purchase. The ambition with this study is to explain how different information channels are used today, which channels that has the best potentials and how the development of these should be done. Interviews with eight different students from Jönköping University underlie the result of this study. During the six latest months these students have purchased a laptop, this purchase has been the starting-point for the interviews. The result shows that the economical and functional risks are those that have been most frequent perceived among our respondents. Requirements concerning price and functionality where also those things that the respondents early in the buyer’s decision process hade a clear opinion about. Functional requirements was in the beginning spoken out as to solve certain needs. These needs have been translated to technical specifications during the process. This translation has been signified with a lot of time spent on seeking information on the Internet. It has also engaged personal contacts with friends etc for valuation of information. Many experiences of information seeking shows on inefficiency. The non-commercial impression that personal contacts and Internet pages, with product comparison, has given is something that we mean should be taken to account in a larger scale. This could be done by actively working with the consumer’s frame of references to the product. Information that is solution orientated, on Internet and from sellers, and which has the ambition to build long term relations has from this reports result shown to have great possibilities for development.

Information technology and political motives, e.g. e-governance, freedom of information legislation, has recent years lead to an increasing emphasis on users and access to records, but little research based knowledge about those issues exist so far. The main focus of the previous research is the use of non-current records in archival repositories. The aim of this thesis is to make a contribution to the research field, in order to gain a better understanding of the information behaviour of users of records in contemporary organizational settings. The research questions addressed are: § How are records used in contemporary organizations?- In what context and for what purposes are records used?- What user categories can be identified? § How is the search for records mediated?- What intermediaries are used in the search process?- How well do the features of the artefactual intermediaries serve the users' information needs?- What is the role of human intermediaries? An additional purpose of the study is to contribute to theory development, and to provide a conceptual model of the information behaviour of users of records that can form the basis for further research. The thesis is based on explorative case studies undertaken in two contemporary Swedish public organizations, one municipality and one governmental agency. Data was collected through interviews, analysis of documentary sources and complementary observations. The analysis of the findings was guided by a theoretical framework consisting of activity theory informed by concepts from archival theory and models of information behaviour. The results of the cases studies showed that information behaviour of users of records and the search process could be described as a part of an activity system. The search process was a sub-ordinated activity of other activities. The needs for records was generated by a task or accomplishment of anykind with purpose to achieve something. Those needs motivated the purposes of use of records: material, operational, accountability seeking or knowledge enhancing purposes. The subjects, users in collaboration with the registrars and archivists, seeked to obtain records with help of different mediational means, e.g. artifactual intermediaries as the journal and the archives inventory that could be defined as representational systems, in order to reach a certain outcome: fact-finding, re-construction of past actions and events, regaining experience and knowledge, verifying status, or illustrating and exemplifying. A variety of user groups, internal as well as external, could be identified in both organizations. Those could act as direct or indirect users, and indirect use by one part meant direct use by another who acted as a mediator between the records and the end users. The external users could be defined as stakeholders of the organizations or other users. Users showed, with occasional exceptions, a preference for informal means of mediation, particularly personal communication. Certain features of the formal representational systems, journals and inventories, could be identified, which made them less useful as search tool. Those were generated by contradictions and tensions within the organizations: contradictions within the representational systems; contradictions between the tasks of the users and the representational systems; contradictions between user requests and the access points in the representational systems; contradictions between external users and the activities of the organizations; contradictions between exogenous institutional conditions and the the activities of the organizations; and contradictions of a temporal character. These circumstances necessitated an active intervention of human intermediaries. This could be seen as an example of the division of labour in the organizations. Search and retrieval of records were part of the registrars’ and the archivists’ specific professional knowledge, but were not considered as primary tasks of other employees or, especially not, of the external users. The results of the study contributes to to the knowledge about the use of records, and how records are approached. It provides a model of the search process that can form the basis for further research. The practical implications of the findings could be improved search tools and user services, i.e. enhanced access. The thesis can also contribute to theoretical enrichment of the field by combining a more comprehensive social theory with archival theory and concepts from information science. / Utveckling av arkiv- och informationsvetenskap

This research investigated whether Group Information Behavioural Norms (GIBNs) are correlated with the effective use of a collaborative information system. Previous research seeking to conceptualize ‘social influence’ in technology adoption has not attempted to include GIBNs. The dependent variable, ‘Effective Use’, comprised two subjective Effectiveness Judgments and three objective Actual Use measures. A mediating variable, ‘Group Adoption’ (GA) of the information system, was conceived as a behavioural expression of group norms and hypothesized to correlate with both GIBNs and Effective Use. It was also hypothesized that GIBNs would have a stronger relationship with Effective Use than the widely used Technology Acceptance Model (TAM) dimensions of Perceived Usefulness and Perceived Ease of Use. A mixed-methods case study approach was used because measurement of stable norms in workplace groups was required. A medium-sized engineering firm was chosen, and the collaborative information system studied was Knowledge Forum (KF), an educational research tool that was implemented to promote the exchange of information. There were both expected and unexpected results. GIBNs outperformed the TAM in explaining all three Actual Use variables, although the TAM was the sole significant correlate for one Effectiveness Judgment variable. Information Sharing and Proactive Information Use had opposite correlations with Effective Use, suggesting the existence of distinct information ‘sharing’ and ‘proactive use’ group norms. In addition, the TAM and GIBNs seem to have complementary influences on Effective Use. GA was unexpectedly observed to have the strongest relationship with Effective Use, having a significant relationship with four of five Effective Use measures. GA was also observed to mediate the TAM but not GIBNs. The results of a case study cannot be extensively generalized. However, the findings are important in three ways. First, this research provides evidence that GIBNs and the TAM exert complementary influences on Effective Use, and that Effective Use is best explained by also including GA. Second, GA may represent a valuable ‘social influence’ extension to the TAM, as a behavioural expression of group norms for collaborative information systems. Finally, this study illustrates the importance of a multi-dimensional conceptualization of ‘Effective Use’ of an information system.
