Background: Information Communication Technologies (ICT)-mediated support can reduce family caregiver burden and may bridge service gaps caused by time constraints and language or cultural barriers. (Non)-usage behaviour can be explained using Andersen’s Behavioural Model of Health Service Utilization, Venkatesh’s Unified Theory of Use and Acceptance of Technology, Eysenbach’s Law of Attrition, and Wilson’s and Chatman’s Information Behaviour Theories. Purpose: This study aimed to describe and explain (non)-usage behaviour of ehealth services among Chinese caregivers. Method: This two-phase study used a mixed methods design involving 46 Chinese caregivers who cared for a family member with dementia. Usability of the ICT tools designed in the study was tested. Phase I participants (N=28) had access to a bilingual information site and personalized email support from professionals. Phase II participants (N=18) were randomized to use one of three enhanced features. Pre- and post-intervention data were collected, and qualitative interviews were conducted. Results: The Phase I ICT tools supported the core functions without major usability issues. Perceived efforts to use the ICT-mediated services influenced the consent decisions of Phase I caregivers (p=.036). Caregivers initiated service earlier if they had a higher acceptance of the service (p=0.017). Frequent users of email support experienced a decline of perceived burden compared with an escalation of perceived burden by non-users (p=0.023). An older age, greater caregiving competence, and lower English or computer proficiency explained non-usage behaviour. Requirements were identified to enhance the Phase I ICT tools. In Phase II, a test of three enhanced features showed there was no major usability issue. The intervention study found the enhanced features did not influence email use as hypothesized. Qualitative analysis showed usage patterns were explained by caregiver needs, caregiving beliefs, personal capacity, social support, ICT factors, and style of use. Non-users preferred Chinese to English compared with users (p=0.046). Integrating the theories and empirical findings, three concepts were developed to explain (non)-usage behaviour: usage in context, usage paths, and stages of use. Conclusion: Usage and non-usage behaviour can be explained by the service needs in the caregiving context, the use of non-ICT-mediated resources, and the access barriers to Internet use. Use of ICT-based support can be beneficial to caregivers if they do not drop out of the service.

Research into the use of information by health care professionals has generally been conducted in countries dominated by the biomedical model. In these contexts, illness is considered to have a scientifically identifiable physical cause, and treatment practices within the formal health care sector are prescribed and managed in accordance with this definition. Yet there are also contexts where other belief systems inform and guide the way that people think about their health. In comparison to the biomedical model, these contexts have contributed very little to our understanding of how health professionals develop their knowledge. This research investigates how primary health care workers (PHCWs) in one such context, Papua New Guinea (PNG), develop their knowledge about the health services they provide. In order to discover and understand the differing views of these PHCWs, 69 semi-structured interviews were conducted in three culturally and geographically diverse regions of PNG. In explaining the diagnostic and treatment practices they use, these participants provided insights into not only how PHCWs engage with information but also how it informs their professional practice. These data were analysed, interpreted and discussed using a framework consisting of four, primary but interconnecting aspects: the context in which information was provided, the interactions with the sources of information, the processes by which information was understood, and the outcomes realized as a result of the information being used. Findings indicated that the majority of participants in this study acknowledged, if not incorporated, information pertaining to biomedicine, Christianity and Indigenous belief systems into their diagnostic and treatment practices. Even when these belief systems clearly contradicted each other, PHCWs did not in general feel the need to make a conscious choice between them. From their comments it would appear that four factors contributed to this ability to incorporate diverse and often conflicting ideas into the way that patients were cared for. First, all of the belief systems were considered legitimate by at least one group of people connected to the community in which the PHCW worked. Second, although varying in degrees of availability and accessibility, members of these groups were able to disseminate information pertaining to the belief system they supported. Third, the PHCW had no particular affiliation with any one of these groups but instead regularly interacted with a range of different people. Lastly, the PHCW worked in situations where health practices were not generally well supervised by their employers and therefore they were relatively free to choose between various diagnostic and treatment practices. The qualitative interpretive approach adopted in this thesis contributes to the field of human information behavior by affirming that conflict is in the eye of the beholder. When a number of belief systems coexist and all are considered legitimate, information about them is freely available, and the recipients actions are neither constrained by their own dogma, nor imposed upon by others, individuals may quite comfortably embrace diverse beliefs. These findings may also contribute to a better understanding of health management practices in developing countries by suggesting that health professionals are not merely personifications of a biomedical model. Instead, the study demonstrates that multiple belief systems can be combined by PHCWs, and that in turn this benefits the formal health care sector through increased treatment options that are both appropriate and effective in such circumstances.

This study involved a qualitative investigation of consulting engineers' information needs and information-seeking behaviour within the context of their project-related work roles and tasks. The research design includes a study of various information behaviour models, a systematic review of the subject literature and the exploration of relevant qualitative research methods. Data was collected through time-line interviews. The findings show how consulting engineers' work roles and tasks determine their information needs during various engineering project stages. These factors also determine the use of various sources during information seeking. Consulting engineers use a variety of information sources but rely mainly on interpersonal communication to gather information. Digital cameras are used by consulting engineers to record progress in a project. They also use Internet technologies such as email and FTP sites to communicate project related information. Recommendations were put forward for the development of an Internet-based information service for consulting engineers. / Information science / M.Inf.

This thesis focuses on Paradox Interactive's information seeking as a process in the construction of historical computer games. The study is collecting data through a series of interviews with two professional groups: Content designers and 3D graphics. The study focuses on the role of information gathering as a internal process in the creation of the game but also on how the two professions, which have been involved in the study's interviews, gather information relevant to their specific tasks. The study also touches on whether it exists a connection between how Content designers and 3D graphics conduct their searches for information and the ABM sector (that is archives, libraries and museums) as sources/distributors of information. The study has resulted in knowledge regarding the professional groups' information behaviour, what factors that affect the process of gathering information. The study has also resulted in an awareness regarding what kind of information sources that are attractive. Furthermore, the interviews conducted have produced information on how archives, libraries and museums function as information sources for the selected professional groups. The information gathered through the interviews shows that archives, libraries and museums are not used as information sources by the professional groups. Reasons as to why this is the case are a lack of awareness as well as the professional groups' various needs, such as right content and easy accessibility. Games which are utilising or relate to popular history are a clear aspect of modern days popular culture. There exists an abundance of games which relate to history whether they are historical strategy-focused computer games or more action-packed videogames constructed around historical events and contexts. There exists an equally abundance of studies which focuses on games in certain aspects; one such area of research is how history is utilised in games. This study, as noted above, doesn't focus on the games themselves or how they utilise history but rather on the specific question of how the developers gather the information about the past, what sources that exists, and how archives, libraries and museums can better accommodate game creators as a specific group of information gatherers and users.

Abstract This dissertation aims to uncover emerging practices in how people seek information while on the move in augmented urban spaces. The backdrop for a majority of the work presented here is the City of Oulu in Finland, where we have installed a variety of new ubiquitous computing infrastructure and services including, among others, a network of large interactive public displays called UBI-hotspots. The hotspots serve as a versatile platform on top of which new types of services can be developed, deployed and tested in an authentic urban setting with real, non-coached users and a sufficiently long timespan to truly evaluate the impact of such services on the everyday life and practices of the city and its citizens. The case studies presented in this dissertation aim at understanding the effect of such highly visible additions to the urban space from the point of view of human information behaviour. I seek to understand the underlying information seeking strategies people employ while foraging the hotspots for information, and the types of information people see as valuable while attending their daily business in the downtown area of the City. Questions such as how do people utilize the new sources of information in their daily information seeking tasks, and what is the preferred medium for information delivery, are addressed. The theoretical framework for the studies is derived from both ubiquitous and urban computing, and from the field of human information behaviour research. The main findings of the presented studies indicate that people have adapted the new infrastructure and services as parts of their daily information seeking tasks. The detailed usage data logged by all hotspots provide insight into the browsing habits of users, and analysis of inter-session navigation show that various latent strategies of information seeking exist. Further, findings indicate that there is a clear difference between the types of services people perceive as useful prior to using the hotspots, and services that people actually use on the hotspots. Also, findings indicate that people are willing to download information items from the hotspots to their mobile devices for later reference, thus adding information to their personal information repository. / Tiivistelmä Tämä väitöskirja pyrkii löytämään ja selittämään uusia tapoja joilla ihmiset etsivät informaatiota älykkäissä kaupunkitiloissa. Tausta suurelle osalle työstä on Oulun kaupunki, jonne olemme asentaneet erilaisia jokapaikan tietotekniikan laitteistoja sekä palveluja. Erityisesti väitöskirjassa tutkitaan suurten julkisten näyttöjen – ”UBI-näyttöjen” – verkostoa. UBI-näytöt toimivat monipuolisena alustana jonka päällä uusia palveluja voidaan kehittää sekä testata autenttisessa kaupunkitilassa todellisten käyttäjien toimesta riittävän pitkällä aikavälillä, joka puolestaan mahdollistaa palveluiden todellisen merkittävyyden arvioimisen suhteessa ihmisten jokapäiväiseen informaatiokäyttäytymiseen sekä informaatiotarpeisiin. Väitöskirjassa esitetyt tapaustutkimukset pyrkivät ymmärtämään tällaisten erittäin näkyvien tietoteknisten laitteiden vaikutusta ihmisten käyttäytymiseen informaatiotutkimuksen näkökulmasta. Tarkastelun kohteena ovat ihmisten jokapäiväiseen tiedonhakuun liittyvät strategiat heidän käyttäessään UBI-näyttöjä, sekä erilaiset informaatiotyypit joita ihmiset pitävät tärkeinä hoitaessaan jokapäiväisiä asioitaan kaupunkitiloissa. Kysymykset kuten kuinka ihmiset käyttävät uusia informaation lähteitä etsiessään tietoa jokapäiväisiin tarpeisiinsa sekä millä laitteilla ihmiset mieluiten etsivät ko. tietoa ohjaavat suurta osaa tutkimuksesta. Tutkimuksen teoreettinen viitekehys muodostuu jokapaikan tietotekniikan tutkimuksesta, urbaanin tietotekniikan tutkimuksesta, sekä ihmisten informaatiokäyttäytymisen tutkimuksesta. Tutkimuksen tärkeimmät löydökset osoittavat että ihmiset ovat ottaneet uudet tietotekniset resurssit osaksi päivittäistä informaatiokäyttäytymistään. Yksityiskohtainen lokitieto yhdistettynä haastattelu- ja havainnointidataan tarjoaa syvällisen näkemyksen käyttäjien tiedontarpeisiin. Dataa analysoimalla olemme havainneet joukon strategioita joita ihmiset käyttävät etsiessään tietoa kaupunkitiloissa. Tutkimus osoittaa myös, että ihmisten oletettujen tiedontarpeiden sekä havainnoidun käyttäytymisen välillä on suuria eroavaisuuksia. Käyttäjät ovat myös halukkaita lataamaan tietosisältöä matkapuhelimiinsa myöhempää käyttöä varten, täten lisäten tietoa omaan henkilökohtaiseen tietovarastoonsa.

This PhD thesis explored the experiences of dependent children and children care-givers facing challenges with their parent s cancer. The aim was to understand children s information experience including their perception of cancer and information culture; information needs, information seeking behaviour, barriers and enablers. The research used a six-stage process. This was informed by an extensive literature review and discussions with cancer specialists, psychologists and researchers from United Kingdom, United States, Australia and Malaysia. This study used a three-cycle, eight-step process of Participative Action Research (PAR) with participation from ten Malay breast cancer patients and their dependent children. Three bilingual (English and Bahasa Malaysia) instruments were developed; 1) An Inquiry to Participate Form to select participants who had dependent children, 2) Three opened-ended questions to obtain children s cancer experience and information needs where drawing was used to encourage children s responses and, 3) A 15-question questionnaire to understand children s experience and information preference. Cancer affected parenting abilities and challenging experiences identified the lack of culturally relevant information and the shift in caregiving responsibilities to dependent children. Children s understanding of cancer was influenced by their experiences and observations, many of which resulted in misconceptions about cancer, its causes, treatment and preventative measures. Children participant s reaction to a health situation triggered their information behaviour. The burden of caregiving and the consequences of a lack of information were greater than anticipated; children had many dimensions of concern and experienced many challenges. This advocated for a more assessable, attractive and sensitive information system. Data synthesis contributed to the development of a Children s Reactive Information Seeking Behaviour An Integrated Model that seeks to explain the relationship between children participants reaction to a health situation and the subsequent processes they undergo to resolve their state of information need.

This dissertation investigates whether video games are able to affect players' attitudes and information behaviour towards depicted historical topics in games over the short- and long-term. We collected data from a sample of 148 young adults. As far as we know, there is currently no study of such a scale focused on historical games. We used, as an intervention tool, a modification of the serious game Czechoslovakia 38-89: Borderlands that deals with the expulsion of the Sudeten Germans from the former Czechoslovakia after WWII. The game is based on historical research providing players with multiple perspectives on the depicted topics. Our control group played a similar game, but where the narrative was unrelated to any depicted historical event from Czechoslovakia 38-89: Borderlands. In the empirical part of the study, we measured explicit and implicit attitude change and information behaviour change towards the expulsion of the Sudeten Germans. Results showed more negative pretest-posttest explicit attitude changes towards the expulsion on a general level (d = -0.34; p = .022) and a specific level (d = -0.53; p = .001) in the experimental group compared to the control group. Over the long-term, group differences in attitude change remained significant for the specific level (d = -0.44; p = .014),...

Although many counter-drone systems such as drone jammers and anti-drone guns have been implemented, drone incidents are still increasing. These incidents are categorized as deviant act, a criminal act, terrorist act, or an unintentional act (aka system failure). Examples of reported drone incidents are not limited to property damage, but include personal injuries, airport disruption, drug transportation, and terrorist activities. Researchers have examined only drone incidents from a technological perspective. The variance in drone architectures poses many challenges to the current investigation practices, including several operation approaches such as custom commutation links. Therefore, there is a limited research background available that aims to study the intercomponent mapping in unmanned aircraft system (UAS) investigation incorporating three critical investigative domains---behavioral analysis, forensic intelligence (FORINT), and unmanned aerial vehicle (UAV) forensic investigation. The UAS forensic intelligence-led taxonomy (U-FIT) aims to classify the technical, behavioral, and intelligence characteristics of four UAS deviant actions --- including individuals who flew a drone too high, flew a drone close to government buildings, flew a drone over the airfield, and involved in drone collision. The behavioral and threat profiles will include one criminal act (i.e., UAV contraband smugglers). The UAV forensic investigation dimension concentrates on investigative techniques including technical challenges; whereas, the behavioral dimension investigates the behavioral characteristics, distinguishing among UAS deviants and illegal behaviors. Moreover, the U-FIT taxonomy in this study builds on the existing knowledge of current UAS forensic practices to identify patterns that aid in generalizing a UAS forensic intelligence taxonomy. The results of these dimensions supported the proposed UAS forensic intelligence-led taxonomy by demystifying the predicted personality traits to deviant actions and drone smugglers. The score obtained in this study was effective in distinguishing individuals based on certain personality traits. These novel, highly distinguishing features in the behavioral personality of drone users may be of particular importance not only in the field of behavioral psychology but also in law enforcement and intelligence.

The purpose of this bachelor’s thesis is to examine information search behaviour of a group of Library and Information Science students in the cultural heritage digital collection cross search service DigitaltMuseum and an evaluation of the cross-search service search functionalities’ usability for the end-user. The study aims in understanding the user search behaviour to let the designers of cultural heritage digital collections websites improve the search tools so that the design matches the real needs of the users. After doing simulated search tasks the informants answered several questions about the chosen search strategies and preferable search functionalities. Quantitative analysis shows that simple search and free keywords are the most preferable search methods, however it is not clear why. On one hand it is observed that the users prefer google-like searching, on the other, discussion on the DigitaltMuseum search functionalities shows lack of use of Knowledge Organisation System of any kind which makes the advanced search tool insufficient.
