The Information-Seeking Behavior of Digital Evidence Examiners

The Information-Seeking Behavior of Digital Evidence Examiners

Date: May 2011
Creator: Yildirim, Idris
Description: The current research sought to gain in-depth insights into the information-seeking behavior of Turkish National Police digital evidence examiners (DEEs); to explore the information sources that DEEs use and the factors affecting their decisions about source selection. Factors that affect information source selection and use by DEEs are: accreditation, workload, type of information, time, cost, availability, reliability/scientific importance, up-to-date data, prior experience with the source, relevance, interactivity and importance. The Internet was the information source most commonly used by participants during the examination stage; other sources included forums, experts, colleagues, forensic tools/kits and books. During the analysis stage, the most frequently mentioned information source was the investigation file, containing information about the elements of the crime; other sources included: personal experience, experts, detectives, the Internet, clients, professional training, the prosecutor, evidence submission forms, in-lab manuals, forums and colleagues. During the report-writing stage, most DEEs used in-lab manuals and report templates as information sources, but previously written reports, editing software, and colleagues were also used to obtain information about the format, style and language of reports as legal documents.

The Information-Seeking Behavior of Police Officers in Turkish National Police

The Information-Seeking Behavior of Police Officers in Turkish National Police

Date: August 2011
Creator: Guclu, Idris
Description: A current trend that has emerged as a result of the information age is information-seeking behavior. From individuals to large social institutions, information-seeking behavior is utilized to attain a wide variety of goals. This body of work investigates the information-seeking behaviors of police officers who work in police stations in the Turkish National Police force. The study utilizes Leckie et al.’s (1996) model of information-seeking behavior of professionals. The findings indicated that police officers initially consulted their personal knowledge and experience. Next, officers rely upon their colleagues and then official documents. These information sources were consulted in the context of both conducting tasks and staying current. However, contrary to expectation, they rarely consulted informants. In addition police officers rarely consulted printed journals, libraries, books and attendance at conferences as information sources. The results of this study show that there were significant differences in the information sources used by police officers based on their gender in the context of staying current. On the other hand, there were no significant differences in the context of conducting police station tasks, by gender. Surprisingly, there were no significant differences in the information sources used by police officers based on their educational level. There were ...

Knowledge-sharing Practices Among Turkish Peacekeeping Officers

Knowledge-sharing Practices Among Turkish Peacekeeping Officers

Date: August 2012
Creator: Eren, Murat Erkan
Description: The Turkish National Police (TNP) peacekeeping officers experience poor knowledge-sharing practices before, during, and after their tours of duty at the United Nations (UN) field missions, thus causing knowledge loss. The study aims to reveal the current knowledge-sharing practices of the TNP peacekeeping officers and proposes a knowledge-sharing system to share knowledge effectively. It also examines how applicable the knowledge management models are for their knowledge-sharing practices. In order to gain a better understanding about the knowledge-sharing practices of TNP officers, the researcher used a qualitative research method in this study. The researcher used semi-structured interviews in data collection. The participants were selected based on the non-probability and purposive sampling method. Content analysis and constant comparison was performed in the data analysis process. The most important knowledge sources of the peacekeeping officers are their colleagues, the Internet, and email groups. The peacekeepers recommend writing reports, organizing training programs, conducting exit interviews, adopting best practices, and creating a knowledge depository. The study uncovers that organizational culture, hierarchy, and physical proximity are significant factors that have a vital impact on knowledge sharing. Knowledge Conversion Model is substantially applicable for the knowledge-sharing practices of the TNP peacekeeping officer.

Middle School Students in Virtual Learning Environments

Middle School Students in Virtual Learning Environments

Date: August 2010
Creator: Wyatt, Erin Drankwalter
Description: 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.

Modeling Student Perception of Web 2.0 Technologies Adoption in Kuwait

Modeling Student Perception of Web 2.0 Technologies Adoption in Kuwait

Date: May 2011
Creator: Alajmi, Mohammad
Description: The primary focus of this dissertation was to explore students' perceptions of adopting Web 2.0 applications at the School of Basic Education (SBE) in Kuwait. Although Web 2.0 applications are becoming more popular among the digital generation, there is still no evidence of students' perceptions of adopting the innovation of Web 2.0 technologies in Kuwait. The problem this study addresses is that the current status of Web 2.0 technologies usage by academic students has remained educationally unknown in Kuwait. Therefore, there was a need to investigate the extent to which academic students in SBE are aware of and their usage of Web 2.0 technologies, as well as the factors and obstacles that affect using these technologies. Rogers' diffusion of innovation theory (DoI) is employed in this study to specify the factors that influence student perceptions of adopting Web 2.0 applications as learning tools. Data used in this dissertation was gathered via a survey instrument from 350 students at the SBE and was statistically analyzed to find out the answers of the research questions. This study identified the low rate of Web 2.0 awareness and adoption by the students. Descriptive statistical analysis, such as mean scores and standard deviation, were used ...

Organizational Justice Perception and Its Effects on Knowledge Sharing: a Case Study of Forensics in the Turkish National Police

Organizational Justice Perception and Its Effects on Knowledge Sharing: a Case Study of Forensics in the Turkish National Police

Date: August 2013
Creator: Can, Ahmet
Description: In today’s economy, organizational knowledge is a fundamental factor for remaining competitive and managing intellectual capital. Knowledge Management aims to improve organizational performance by designing the work environment with necessary tools. Yet, significant amount of knowledge resides within the people in different forms such as experience or abilities. Transferring individual knowledge within members or into organizational repositories is so difficult. Knowledge sharing only occurs under certain circumstances: People share knowledge when they believe it is beneficial for them, when they feel safe and secure, and when they trust. Since knowledge is power, and brings respect to its bearer, knowledge sharing needs suitable environment. In this context, this study investigates intention to knowledge sharing among forensics in the Turkish National Police (TNP) and the factors -such as perceived organizational justice, organizational citizenship behaviors, subjective norms, and attitudes toward knowledge sharing- affecting their intentions. The researcher utilized a model developed from Ajzen and Fishbein’s (1975; 1980) theory of reasoned action (TRA). To test this model, a self-administered questionnaire survey was administered in Turkey In order to analyze the quantitative data; SPSS version 19 was used for all preliminary analyses and LISREL 8.8 was used for Regression Analysis and Path Analysis The fit ...

The Role of Tasks in the Internet Health Information Searching of Chinese Graduate Students

Date: May 2012
Creator: Pan, Xuequn
Description: The purpose of the study was to examine the relationships between types of health information tasks and the Internet information search processes of Chinese graduate students at the University of North Texas. the participants' Internet information search processes were examined by looking at the source used to start the search, language selection, use of online translation tools, and time spent. in a computer classroom, 45 Chinese graduate students searched the Internet and completed three health information search tasks: factual task, interpretative task, and exploratory task. Data of the Chinese graduate students’ health information search processes were gathered from Web browser history files, answer sheets, and questionnaires. Parametric and non-parametric statistical analyses were conducted to test the relationships between the types of tasks and variables identified in the search process. Results showed that task types only had a statistically significant impact on the time spent. for the three tasks, the majority of Chinese graduate students used search engines as major sources for the search starting point, utilized English as the primary language, and did not use online translation tools. the participants also reported difficulties in locating relevant answers and recommended ways to be assisted in the future when searching the Internet ...

Seeking Information After the 2010 Haiti Earthquake: a Case Study in Mass-fatality Management

Seeking Information After the 2010 Haiti Earthquake: a Case Study in Mass-fatality Management

Date: May 2013
Creator: Gupta, Kailash
Description: The 2010 earthquake in Haiti, which killed an estimated 316,000 people, offered many lessons in mass-fatality management (MFM). The dissertation defined MFM in seeking information and in recovery, preservation, identification, and disposition of human remains. Specifically, it examined how mass fatalities were managed in Haiti, how affected individuals sought information about fatalities, and what needs motivated them. Data from 28 in-depth, partially structured interviews, conducted during two field visits ending 21 weeks after the earthquake, were included in a case study. The data analysis revealed the MFM was severely inadequate. One interviewee, a senior UN official, stated, "There was no fatality management." The analysis also indicated a need to learn whereabouts of the deceased motivated individuals to visit spots the deceased were last seen at. It sought to illumine information-seeking practices, as discussed in the works of J. David Johnson and others, by developing a new model of information flow in MFM. In addition, it reaffirmed Donald Case and Thomas Wilson's theoretical proposition – that need guides any seeking of information – in the case of Haiti. Finally, it produced recommendations regarding future directions in MFM for emergency managers and information scientists, including possible use of unidentified body parts in ...

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

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

Date: December 2010
Creator: Slagle, Tisha Anne
Description: 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.

Social Media in Policing: a Study of Dallas-fort Worth Area City Police Departments

Social Media in Policing: a Study of Dallas-fort Worth Area City Police Departments

Date: August 2013
Creator: Altunbas, Fuat
Description: Social media offers numerous opportunities to companies, organizations and government agencies to communicate with people outside their organization, to promote their interests and to better serve their customers, or as in the case with government agencies, to better serve their citizens. However, little is known about how police departments in particular use social media. This research study explores why police departments use social media, how they manage their social media tools, and the problems and challenges experienced as they use social media. This qualitative study is largely guided by grounded theory. The data were collected from a study population using local police departments in the Dallas-Fort worth (DFW) area principal cities using both individual interviews with police departments’ social media officers and observations of these departments’ online social media tools (in particular, Facebook and Twitter). This study has shown that the DFW area city police departments are using social media quite extensively to keep the public informed and often for investigative purposes. There are some success factors to adopting and using these tools, such as the motivation of department staff and their benefits, successful implementation of the tools, the simplicity of using tools and that it is absolutely free.
