Factors Related to the Selection of Information Sources: A Study of Ramkhamhaeng University Regional Campuses Graduate Students

Factors Related to the Selection of Information Sources: A Study of Ramkhamhaeng University Regional Campuses Graduate Students

Date: August 2011
Creator: Angchun, Peemasak
Description: This study assessed students’ satisfaction with Ramkhamhaeng University regional library services (RURLs) and the perceived quality of information retrieved from other information sources. In particular, this study investigated factors relating to regional students’ selection of information sources to meet their information needs. The researcher applied the principle of least effort and Simon’s satisficing theory for this study. The former principle governs and predicts the selection of these students’ perceived source accessibility, whereas the latter theory explains the selection and use of the information retrieved without considering whether the information is optimal. This study employed a web-based survey to collect data from 188 respondents. The researcher found that convenience and ease of use were the top two variables relating to respondent’s selection of information sources and use. The Internet had the highest mean for convenience. Results of testing a multiple linear regression model of all four RURCs showed that these four independent variables (convenience, ease of use, availability, and familiarity) were able to explain 69% of the total variance in the frequency of use of information sources. Convenience and ease of use were able to increase respondents’ perceived source accessibility and explain the variance of the frequency of use of sources ...

Graduate Students' Collaborative Information Seeking in a Group-based Learning Setting

Graduate Students' Collaborative Information Seeking in a Group-based Learning Setting

Date: May 2013
Creator: Lee, Jisu
Description: Working with others within an organization can have a variety of positive effects, and the benefits of collaboration have been discussed in various disciplines. In information science, interest in collaborative information seeking, including collaborative information seeking by students in an online learning environment is expanding. This study was aimed at understanding graduate students' collaborative information seeking behaviors through the process of a group project, including factors that affected students' perceptions of collaborative work and their difficulties during the collaborative process. The research was based on Yue and He's model, which describes information users' collaborative communication and information behaviors, and Kuhlthau's model, which describes users' individual information seeking behaviors. The participants were 43 students enrolled in a master's level course delivered primarily online. The students were required to work together in groups to complete a research project. Data were collected through a background survey, behavior survey, and online communication texts and analyzed using descriptive statistics, statistical tests, and content analyses. The results showed significant changes in collaborative and information seeking behaviors and perceptions across three stages of the project during the semester. Theoretical, practical, and methodological implications for future research are discussed.

Image Representation and Interactivity: An Exploration of Utility Values, Information-Needs and Image Interactivity

Image Representation and Interactivity: An Exploration of Utility Values, Information-Needs and Image Interactivity

Date: August 2011
Creator: Lewis, Elise C.
Description: This study was designed to explore the relationships between users and interactive images. Three factors were identified and provided different perspectives on how users interact with images: image utility, information-need, and images with varying levels of interactivity. The study used a mixed methodology to gain a more comprehensive understanding about the selected factors. An image survey was used to introduce the participants to the images and recorded utility values when given a specific task. The interviews allowed participants to provide details about their experiences with the interactive images and how it affected their utility values. Findings from the study showed that images offering the highest level of interactivity do not always generate the highest utility. Factors such as personal preference, specifically speed and control of the image, affect the usefulness of the image. Participant also provided a variety of uses where access to interactive images would be beneficial. Educational settings and research tools are a few examples of uses provided by participants.

The Impact of Leadership Styles and Knowledge Sharing on Police Officers’ Willingness to Exert Extra Effort to Provide Better Security: A Study in the Riot Unit of the Turkish National Police

The Impact of Leadership Styles and Knowledge Sharing on Police Officers’ Willingness to Exert Extra Effort to Provide Better Security: A Study in the Riot Unit of the Turkish National Police

Date: August 2011
Creator: Tombul, Fatih
Description: The motivation for this study is to understand the factors affecting police officers’ willingness to exert extra effort for providing better service through knowledge sharing in different working environments such as riots. Since managers’ leadership styles may be important factors affecting subordinates’ willingness to exert extra effort, this study investigates which of the leadership styles -- transformational, transactional or laissezfaire leadership -- will have a positive effect on officers’ willingness to exert extra effort. In addition, the current study also examines the effect of the mentioned leadership styles on knowledge sharing, which, in turn, affects the officers’ willingness to exert extra effort in the riot unit of the Turkish National Police (TNP) in Ankara, Turkey. The sworn line police officers working in the riot unit in Ankara, Turkey, were the participants in this study. Three questionnaires --a Multifactor Leadership (MLQ), knowledge sharing, and demographic questionnaire -- were arranged as a booklet to be distributed to the respondents. The results of the study indicate that police supervisors' perceived transformational leadership behavior has a positive effect on officers' willingness to exert extra effort. In addition, the findings also reveal that although both officers' years of service in TNP and police supervisors' perceived ...

Implications of Punctuation Mark Normalization on Text Retrieval

Implications of Punctuation Mark Normalization on Text Retrieval

Date: August 2013
Creator: Kim, Eungi
Description: This research investigated issues related to normalizing punctuation marks from a text retrieval perspective. A punctuated-centric approach was undertaken by exploring changes in meanings, whitespaces, words retrievability, and other issues related to normalizing punctuation marks. To investigate punctuation normalization issues, various frequency counts of punctuation marks and punctuation patterns were conducted using the text drawn from the Gutenberg Project archive and the Usenet Newsgroup archive. A number of useful punctuation mark types that could aid in analyzing punctuation marks were discovered. This study identified two types of punctuation normalization procedures: (1) lexical independent (LI) punctuation normalization and (2) lexical oriented (LO) punctuation normalization. Using these two types of punctuation normalization procedures, this study discovered various effects of punctuation normalization in terms of different search query types. By analyzing the punctuation normalization problem in this manner, a wide range of issues were discovered such as: the need to define different types of searching, to disambiguate the role of punctuation marks, to normalize whitespaces, and indexing of punctuated terms. This study concluded that to achieve the most positive effect in a text retrieval environment, normalizing punctuation marks should be based on an extensive systematic analysis of punctuation marks and punctuation patterns and ...

In Pursuit of Image: How We Think About Photographs We Seek

In Pursuit of Image: How We Think About Photographs We Seek

Date: May 2012
Creator: Oyarce, Sara
Description: The user perspective of image search remains poorly understood. the purpose of this study is to identify and investigate the key issues relevant to a user’s interaction with images and the user’s approach to image search. a deeper understanding of these issues will serve to inform the design of image retrieval systems and in turn better serve the user. Previous research explores areas of information seeking behavior, representation in information science, query formulation, and image retrieval. the theoretical framework for this study includes an articulation of image search scenarios as adapted from Yoon and O’Connor’s taxonomy of image query types, Copeland’s Engineering Design Approach for rigorous qualitative research, and Anderson’s Functional Ontology Construction Model for building robust models of human behavior. a series of semi-structured interviews were conducted with expert-level image users. Interviewees discussed their motivations for image search, types of image searches they pursue, and varied approaches to image search, as well as how they decide that an information need has been met and which factors influence their experience of search. a content analysis revealed themes repeated across responses, including a collection of 23 emergent concepts and 6 emergent categories. a functional analysis revealed further insight into these themes. ...

Information Censorship: A Comparative Analysis of Newspaper Coverage of the Jyllands-Posten Editorial Caricatures in Cross-Cultural Settings

Information Censorship: A Comparative Analysis of Newspaper Coverage of the Jyllands-Posten Editorial Caricatures in Cross-Cultural Settings

Date: August 2010
Creator: Thomas, Julie George
Description: The identification and examination of cultural information strategies and censorship patterns used to propagate the controversial issue of the caricatures in two separate cultural contexts was the aim of this dissertation. It explored discourse used for the coverage of this topic by one newspaper in a restrictive information context and two newspapers in a liberal information context. Message propagation in a restrictive information environment was analyzed using the English daily Kuwait Times from the Middle East; the liberal information environment of the US was analyzed using two major dailies, the New York Times and the Philadelphia Inquirer. The study also concurrently identifies and elaborates on the themes and frames through which discourse was presented exposing the cultural ideologies and premises they represent. The topic was approached with an interdisciplinary position with the support and applicability testing of Chatman's insider-outsider theory within information science and Noelle-Neumann's spiral of silence theory and Herman and Chomsky's propaganda model based in the area of mass communication. The study has also presented a new model of information censorship - circle of information censorship, emphasizing conceptual issues that influence the selection and censorship of information.

Information Literacy Skills in the Workplace: A Study of Police Officers

Information Literacy Skills in the Workplace: A Study of Police Officers

Date: August 2010
Creator: Kilic, Osman
Description: Information literacy has become more important as more information is produced and communication has become easier. Better information skills are vital for individuals working in governmental organizations as well as in the business sector. Employees are expected to be confident and competent in interacting with information in their workplaces in order to deliver better service to customers and to the public. This study examines the differences in information literacy skills (ILS), computer literacy skills (CLS), and frequencies of use of information sources (FIS) among police officers, based on their socio-demographic characteristics, namely education, departmental affiliation, ranks, and experience. Information literacy process models developed in an educational environment are combined to explore information literacy process in the workplace. Bivariate and multivariate analyses indicated significant differences of ILS and CLS based on education, departmental affiliation, and ranks but no difference for experience. In addition, there were differences of FIS for all demographic variables except departmental affiliation. The findings of the study may guide both future researchers in the process of developing new models in understanding information literacy process and the managers in police organizations in planning better training programs by considering information and computer literacy skills and use of information sources of ...

The Information Politics Assessment Scale (Ipas): Developing and Testing an Instrument to Measure and Identify the Information Politics of Organizations

The Information Politics Assessment Scale (Ipas): Developing and Testing an Instrument to Measure and Identify the Information Politics of Organizations

Date: May 2014
Creator: Reed, Richard
Description: Information politics is a concept widely acknowledged in several disciplines. However, scant empirical evidence exists in the literature that codifies or measures information politics as a construct. This exploratory study developed and tested the Information Politics Assessment Scale (IPAS), a survey instrument that measured individual perceptions of organizational information artifacts as indictors of its information politics. Data collected with the IPAS was examined to investigate the latent structure of the information politics variable, determine information politics models, and explore the relationship between information politics, strategy, and organization effectiveness. A purposive sample of 240 participants from a cross-section of organizations completed the IPAS in an online administration. Exploratory factor analysis generated three factors, labeled Behavioral Flexibility (BF), Environmental Sensitivity (ES), and Structural Autonomy (SA), suggesting three dimensions of the information politics variable. Cluster analysis of aggregate scores on the BF, ES, and SA factors together resulted in determining four distinct information politics models. Crosstab and ANOVA, respectively, enabled explaining the relationship between strategy and information politics, and how it influenced organization effectiveness. This study breaks ground by broadening the theoretical and empirical understanding of information politics in confirming the proposition that an organization’s information artifacts are measureable and reliable indicators of ...

Information Seeking Behavior of Crime Scene Investigators in the Turkish National Police

Information Seeking Behavior of Crime Scene Investigators in the Turkish National Police

Date: May 2010
Creator: Demircioglu, Mehmet
Description: This exploratory research is the first one among occupational information seeking behavior studies that focuses on information seeking behaviors of the crime scene investigators. The data used in this dissertation were gathered via a self-administrated survey instrument from 29 cities in Turkey. Findings obtained from the data analyses show that there is a strongly positive relationship between the experience of the crime scene investigators and the use of personal knowledge and experience as a primary information source (experience is operationalized with age, service years in policing, and service years in crime scene investigation units). The findings also suggest that increasing of the level of education is negatively related to relying on immediate colleagues as an information source among the crime scene investigators. These findings are consistent with related literature and theory. The data analysis shows that crime scene investigators work in cities with higher population rates have more complaint scores than those who work in cities with lower population rates across Turkey. The findings from the data analysis may suggest valuable implications to defeat the barriers between crime scene investigators and information sources. The researcher drew a proposed theoretical framework of an information behavior concept in the context of crime ...
