Comparing the Readability of Text Displays on Paper, E-Book Readers, and Small Screen Devices

Science fiction has long promised the digitalization of books. Characters in films and television routinely check their palm-sized (or smaller) electronic displays for fast-scrolling information. However, this very technology, increasingly prevalent in today's world, has not been embraced universally. While the convenience of pocket-sized information pieces has the techno-savvy entranced, the general public still greets the advent of the e-book with a curious reluctance. This lack of enthusiasm seems strange in the face of the many advantages offered by the new medium - vastly superior storage capacity, searchability, portability, lower cost, and instantaneous access. This dissertation addresses the need for research examining the reading comprehension and the role emotional response plays in the perceived performance on e-document formats as compared to traditional paper format. This study compares the relative reading comprehension on three formats (Kindle, iTouch, and paper) and examines the relationship of subject's emotional response and relative technology exposure as factors that affect how the subject perceives they have performed on those formats. This study demonstrates that, for basic reading comprehension, the medium does not matter. Furthermore, it shows that, the more uncomfortable a person is with technology and expertise in the requested task (in this case, reading), the …

Using Financial Rankings to Identify Characteristics of Libraries Serving Highly Profitable Private Law Firms (open access)

Using Financial Rankings to Identify Characteristics of Libraries Serving Highly Profitable Private Law Firms

This purpose of this study was to develop evidence of a relationship between law libraries and private law firm profitability for law library administrators to use when making strategic decisions that influence the value of their libraries. The highest ranked administrator at each private law firm listed on the 2008 Am Law 200 was invited to complete an online benchmarking survey. The adjusted sample population totaled 179 firms. Fifty-one valid surveys were completed for a 28.5% response rate. Descriptive and statistical analyses were conducted using 26 independent variables (law library characteristics) and a single dependent variable, Revenue per Equity Partner, developed from data published for the Am Law 200. The most significant contributions of this study are: development of important law library financial and return on investment benchmarks; a listing of characteristics that have been empirically shown to impact law firm productivity; identification of optimum reporting structure for the law library administrator. Six characteristics positively impact Revenue per Equity Partner: to whom the library Administrator reports, number of library staff per library, number of Library staff per library, range in hourly bill rate for library staff time, practice areas most often supported. Two monetary measures were also established. The cost …

Information Seeking Behavior of Crime Scene Investigators in the Turkish National Police (open access)

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

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 …

Information Literacy Skills in the Workplace: A Study of Police Officers (open access)

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

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 …

User Acceptance of North Central Texas Fusion Center System by Law Enforcement Officers (open access)

User Acceptance of North Central Texas Fusion Center System by Law Enforcement Officers

The September 11 terrorist attacks pointed out the lack of information sharing between law enforcement agencies as a potential threat to sound law enforcement in the United States. Therefore, many law enforcement agencies as well as the federal government have been initiating information sharing systems among law enforcement agencies to eradicate the information sharing problem. One of the systems established by Homeland Security is the North Central Texas Fusion Center (NCTFC). This study evaluates the NCTFC by utilizing user acceptance methodology. The unified theory of acceptance and the use of technology is used as a theoretical framework for this study. Within the study, user acceptance literature is examined and various models and theories are discussed. Furthermore, a brief information regarding the intelligence work done by law enforcement agencies are explained. In addition to the NCTFC, several major law enforcement information systems are introduced. The data for this study comes from the users of the NCTFC across the north central Texas region. Surveys and interviews are used to triangulate data. It is found in this study that performance expectancy and effort expectancy are important indicators of system use. Furthermore, outreach and needs assessment are important factors in establishing systems. The results …

The Situational Small World of a Post-disaster Community: Insights into Information Behaviors after the Devastation of Hurricane Katrina in Slidell, Louisiana (open access)

The Situational Small World of a Post-disaster Community: Insights into Information Behaviors after the Devastation of Hurricane Katrina in Slidell, Louisiana

Catastrophes like Katrina destroy a community's critical infrastructure-a situation that instigates several dilemmas. Immediately, the community experiences information disruption within the community, as well as between the community and the outside world. The inability to communicate because of physical or virtual barriers to information instigates instant isolation. Prolonged, this scarcity of information becomes an information poverty spell, placing hardship on a community accustomed to easily accessible and applicable information. Physical devastation causes the scarcity of what Abraham Maslow calls basic survival needs-physiological, security, and social-a needs regression from the need to self-actualize, to meet intellectual and aesthetic needs. Because needs regress, the type of information required to meet the needs, also changes-regresses to information regarding survival needs. Regressed information needs requires altered information behaviors-altered methods and means to meet the information needs of the post-disaster situation. Situational information behavior follows new mores-altered norms-norms constructed for the post-disaster situation. To justify the unconventional, situational social norms, residents must adjust their beliefs about appropriate behavior. Situational beliefs support situational social norms-and situational information behaviors prevail. Residents find they must trust strangers, create makeshift messaging systems, and in some cases, disregard the law to meet their post-disaster survival needs.

Effects of Tasks on Information-Seeking Behavior in a Police Work Environment in the Context of Criminal Intelligence (open access)

Effects of Tasks on Information-Seeking Behavior in a Police Work Environment in the Context of Criminal Intelligence

Although dominant effects of tasks on individuals' information-seeking behavior is accepted by many scholars, a limited number of studies has been conducted to reveal the nature of the relationship between tasks and information-seeking behavior. In their studies, some earlier researchers categorized tasks according to their complexity while others did the same according to the specifications of tasks. Two of the groundbreaking researchers in this area are Katriina Byström and Kalervo Järvelin who contributed to the understanding of the relationship between task complexity and information-seeking behavior. However, their findings also need empirical support for theory growth. In response to this need, this study attempts to test Byström and Järvelin's findings through a research using different research methods and applied in a police work environment. Other than providing empirical support for theory growth, this research is also expected to contribute to the understudied area of police information-seeking behavior. Both qualitative and quantitative data were collected from the participants who came from traffic, homicide, and anti-terrorism divisions of Ankara, Eskisehir, and Kirikkale Police Departments in Turkey. The participants identified terrorism cases as the most complex cases to solve, followed by homicide and traffic accident cases. Differences in the information-seeking behavior of three groups …

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

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

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.

Middle School Students in Virtual Learning Environments (open access)

Middle School Students in Virtual Learning Environments

This ethnographic study examined middle school students engaged in a virtual learning environment used in concert with face-to-face instruction in order to complete a collaborative research project. Thirty-eight students from three eighth grade classes participated in this study where data were collected through observation of student work within the virtual learning environment, an online survey, and focus group sessions with students involved in the project. Results indicated students found the virtual learning environment to be valuable as a platform to complete a collaborative research assignment because of portability, ease of use, and organization. Embedded resources within the environment were helpful because of the convenience. Other people, including peers and teachers, were the preferred source of help when problems navigating the environment or finding information arose. Students communicated within the virtual learning environment as a social outlet, a way to check in, and a means to offer content related comments. Ideally the study's findings will give insight into student experiences in a virtual learning environment in order to help educators design more effective learning experiences and incorporate useful supports within such environments.
