Discusses the development of an online restaurant recommendation system that allows users to search for restaurants in the Los Angeles area. The user can retrieve restaurant information including, name, type of restaurant, address, phone number, rating, prices and map. By logging in, users can also give their own recommendations and rate restaurants. The system also provides functions that allow a system a system administrator to manage the contents of the site. The project is based on Java Server Pages (JSP) language, Java Server Programming, which is a server side scripting language. Utilizes MySQL to maintain persistent data and Tomcat as a web system server.

In the UK angina affects 2 million people (BHF, 2010b) and unfortunately secondary prevention interventions such as Cardiac Rehabilitation (CR) are not widely available for this population (NACR, 2011). This doctoral research project examined the effectiveness and feasibility of an alternative intervention for this population; CR delivered via the internet. The programme was interactive and comprised personalised goal setting orientated around exercise, diet, emotions, and smoking with support available through an online email link or synchronised chat room. A randomised controlled trial (RCT) and semi-structured interviews were used to evaluate the intervention. Primary care patients with angina were randomised to either an intervention group (n=48) or to a control group that did not receive any intervention other than treatment as usual (n=47). Outcome measures were taken at baseline, 6 week and 6 month follow ups. The primary outcome measure was daily steps (measured objectively using Sensewear Pro 3® accelerometer technology). Secondary outcome measures included daily energy expenditure (EE), daily duration of sedentary activity (DDSA), daily duration of moderate activity (DDMA), daily duration of vigorous activity (DDVA), weight, diastolic blood pressure (DBP), systolic blood pressure (SBP), body fat %, fat intake, fibre intake, anxiety, depression, self-efficacy, and health related quality of life (HRQOL). At the 6 week follow up the intervention group had greater improvements than the control group in daily steps, daily EE, DDSA, DDMA, weight, self-efficacy, emotional quality of life and frequency of angina symptoms. In addition, at the 6 month follow up there were significantly greater improvements in anxiety, and frequency of angina symptoms among the intervention group compared to the control group. Semi-structured interviews were also conducted with a subsample of intervention group participants at the 6 week follow up (n=16). Themes resulting from these interviews indicated a high level of programme acceptability and feasibility; ‘self reported improvements’ and ‘programme facilitators’. However, the theme labelled ‘programme barriers’ illustrated intervention related challenges which should be taken into account when delivering the programme. Overall the study demonstrated that a new web based CR programme was effective at improving lifestyle related cardiac risk factors for a primary care angina population in both the short-term (significantly improved daily steps, DDSA, DDMA, weight, self-efficacy, emotional QOL and frequency of angina) and medium-term (significantly improved anxiety, and frequency of angina). These findings on the whole suggest that the programme could be offered to a primary care angina population who are not routinely included within conventional CR. However, there is a need to consider the factors described to affect engagement of the programme; family and work commitments, bad weather, older age, receiving the programme late in angina diagnosis and levels of self-motivation.

Grundlage für die Erweiterung um diesen zeitgemäßen Informationskanal ist eine leistungsfähige Wissensbasis, die auch im bereits abgeschlossenen Projekt Bibliotheksportal Sachsen www.bibliotheksportalsachsen.de im Einsatz ist.

In recent years, virtual communities have become increasingly popular among online users and businesses. Public press has shown a strong interest in virtual communities and announced their informational value. The explosive growth of virtual communities has aroused tremendous interest among academic researchers as well. Academic researchers have noticed that participation dynamics of virtual communities among online users create valuable information that influences subsequent economic outcome. However, relatively little research has explored the underlying motives of passive and active participation in virtual communities. In particular, research explicating how the information created by user participation influences users’ economic decisions has not been investigated. To investigate user participation dynamics and the resulting informational value of virtual communities, I explore three major issues in my dissertation. First, I investigate the determinants of passive and active users of virtual communities using survey data from 502 online investors. The results indicate that social, psychological, and community factors influence two different behavioral intentions – the intention to share and the intention to seek. For instance, social factors such as reputation seeking increase the intention to share in virtual communities, whereas psychological factors such as perceived knowledge deteriorate the intention to seek. Second, I explore how an online investor processes information posted on virtual communities and its subsequent economic outcomes by conducting a field experiment. I find that psychological bias (e.g., confirmation bias) influences investors’ information processing behaviors, which ultimately leads to a low return of investment as compared to economic rationales. Following this line of exploration, I empirically examine the relative informational impact of virtual communities on users’ decisions and market performance in the context of electronic markets. Using customer review data from a well-known online retailer and from three third-party customer review websites, I find that consumers obtain product information from external information sources during the information search stage for high involvement products and are thus less influenced by retailer-hosted information. All in all, my dissertation contributes to the understanding of user participation dynamics and informational value of virtual communities by investigating users’ information processing behavior and the subsequent economic outcomes and performance. / text

Title: Blog Influence on Consumer Information Search Authors: Emma Hammer, Charlotta Hellström & Emma Martin Tutor: Jonas Dahlqvist Date: 2015-05-11 Key Words: Blog marketing, information search, blog characteristics, blog influence, consumer behavior, online information, online communication Abstract Information search is crucial to consumers because it can potentially lead to better decision-making, therefor it is argued to be the most important aspect during the consumer decision process (Beatty & Smith, 1987; Schmidt & Spreng, 1996). The Internet has greatly impacted the way consumers search for information (Peterson & Merino, 2003). The easy access of online information has made consumers to turn to blogs as an information source, to find inspiration and to be entertained. Moreover, the opportunity to interact with bloggers increases trust and thus consumers feel a stronger connection to the information being shared (Piscopo, 2015).   This thesis intends to analyze and describe what influences consumers to use blogs as an information source and why consumers continuously use blogs over traditional media. To be able to fully understand the use of blogs, the most influential characteristics of blogs affecting consumer behavior are investigated. This thesis discusses similarities and differences with existing literature concerning blogs and consumer behavior and intends to narrow the knowledge gap on the topic.   To fulfill the purpose of this thesis, existing literature was carefully studied to gain knowledge of the topic and qualitative primary data was collected through personal interviews to gain insights from consumers’ perspectives among experienced blog readers. The interview questions were developed based on the theory and previous literature addressed in this study.   The findings of our study indicated that all of the respondents were influenced to read blogs both internally and externally. Our study showed that consumers prefer using blogs as an information source over traditional media because it is easily accessible, free and more convenient. Finally, the continuous use of blogs was realized as a result of these blog characteristics explained by the respondents: familiarity, frequency, convenience, inspirational, humor and professionalism.

With the technological development of the last decades, an increasing number of genealogists are carrying out their research online. The purpose of this master’s thesis is to examine how and why genealogists' information behavior has been influenced by the use of online services for genealogy. Using a conceptual model of genealogists' information behavior as theoretical basis for the study, I examine how the use of online services affect genealogists’ search process, what information they are looking for and what information resources they use. Data is collected by seven qualitative interviews with experienced genealogists.The interviews indicate that online services have not completely taken over the genealogists’ search for information. Genealogists still went to physical repositories for a number of reasons. However, all participants in the study agreed that their visits to physical repositories and their use of physical records had declined since they began to use online services. The search for information was perceived to have become easier and more convenient with online services, although participants also acknowledged the risks of misleading information. Online services for genealogy also seem to have an influence on the contact between genealogists, especially on international contacts. This, together with the increasing research on foreign material, indicates that genealogy has been internationalized as a result of the use of online services. To the extent that the use of online services affects genealogists' information behavior, it seems in large part to be a result of online services removing geographical barriers that previously influenced genealogists’ information behavior. This is a two years master’s thesis in Archival Science.
