Modeling the Role of Boundary Spanners-in-Practice in the Nondeterministic Model of Engineering Design Activity

Modeling the Role of Boundary Spanners-in-Practice in the Nondeterministic Model of Engineering Design Activity

Date: December 2015
Creator: Linkins, Kathy L
Description: Boundary spanners-in-practice are individuals who inhabit more than one social world and bring overlapping place perspectives to bear on the function(s) performed within and across each world. Different from nominated boundary spanners, they are practitioners responsible for the 'translation' of each small world's perspectives thereby increasing collaboration effectiveness to permit the small worlds to work synergistically. The literature on Knowledge Management (KM) has emphasized the organizational importance of individuals performing boundary spanning roles by resolving cross-cultural and cross-organizational knowledge system conflicts helping teams pursue common goals through creation of "joint fields" - a third dimension that is co-jointly developed between the two fields or dimensions that the boundary spanner works to bridge. The Copeland and O'Connor Nondeterministic Model of Engineering Design Activity was utilized as the foundation to develop models of communication mechanics and dynamics when multiple simultaneous interactions of the single nondeterministic user model, the BSIP and two Subject Matter Experts (SMEs), engage during design activity in the Problem-Solving Space. The Problem-Solving Space defines the path through the volumes of plausible answers or 'solution spaces' that will satisfice the problem presented to the BSIP and SMEs. Further model refinement was performed to represent expertise seeking behaviors and the physical ...

Enhancing User Search Experience in Digital Libraries with Rotated Latent Semantic Indexing

Enhancing User Search Experience in Digital Libraries with Rotated Latent Semantic Indexing

Access: Use of this item is restricted to the UNT Community.
Date: August 2015
Creator: Polyakov, Serhiy
Description: This study investigates a semi-automatic method for creation of topical labels representing the topical concepts in information objects. The method is called rotated latent semantic indexing (rLSI). rLSI has found application in text mining but has not been used for topical labels generation in digital libraries (DLs). The present study proposes a theoretical model and an evaluation framework which are based on the LSA theory of meaning and investigates rLSI in a DL environment. The proposed evaluation framework for rLSI topical labels is focused on human-information search behavior and satisfaction measures. The experimental systems that utilize those topical labels were built for the purposes of evaluating user satisfaction with the search process. A new instrument was developed for this study and the experiment showed high reliability of the measurement scales and confirmed the construct validity. Data was collected through the information search tasks performed by 122 participants using two experimental systems. A quantitative method of analysis, partial least squares structural equation modeling (PLS-SEM), was used to test a set of research hypotheses and to answer research questions. The results showed a not significant, indirect effect of topical label type on both guidance and satisfaction. The conclusion of the study is ...

An Examination of the Role of Corporate Governance Structure in the Implementation of Enterprise Resource Planning (Erp) Systems: an International Perspective

An Examination of the Role of Corporate Governance Structure in the Implementation of Enterprise Resource Planning (Erp) Systems: an International Perspective

Date: August 2015
Creator: Obitade, Oluseyi Peter
Description: Enterprise resource planning (ERP) systems are regarded as among the most innovative information technology products developed over the past two decades. Thus, they have become the backbone of management information systems in the organizations that have implemented them. The difficulties associated with their high failure rate, however, have been the subject of extensive studies. To expand on this knowledge, this study has two research objectives: to examine the relationship between corporate governance structures and implementation results and to investigate whether implementation outcomes vary by country. This study focuses on the project steering committee’s involvement, internal auditors’ participation, and the change management plan implementation. The results demonstrate that steering committee involvement is a primary factor that influenced the success of ERP implementation; and that institutional factors in country of deployment are important determinants of ERP project outcome.

Information Use Environment of Religious Professionals: a Case Study OfThe Everyday Life Information Seeking Behavior of Catholic Clergy in Northern Nigeria

Information Use Environment of Religious Professionals: a Case Study OfThe Everyday Life Information Seeking Behavior of Catholic Clergy in Northern Nigeria

Date: August 2015
Creator: Dankasa, Jacob
Description: This study explores the everyday life information seeking (ELIS) behavior of Catholic clergy in Northern Nigeria and describes their information use environment (IUE). It employed a mixed-method case study using survey and episodic interview techniques of data collection. The ELIS of Savolainen, the IUE of Taylor and the small world of Chatman were theoretical frameworks that guided this study. Findings showed that the IUE of these Catholic clergy is shaped by four elements: (1) geographical location and culture, (2) the celibate clergy, (3) their information needs, and (4) the information sources used to resolve these needs. Three types of information needs were identified: essential needs, circumstantial needs and intermittent needs. There was a high interrelatedness between the effects of culture and celibacy on the information seeking of these clergy. They are not likely to cross boundaries of their world to seek particularly essential information about their ministry or private lives. The findings of this study align with Chatman’s proposition that members who live in the round will not cross the boundaries of their world to seek information. The study found problems with access and availability of information, which included lack of familiarity with electronic/online library databases among the clergy, and ...

Automatic Language Identification for Metadata Records: Measuring the Effectiveness of Various Approaches

Automatic Language Identification for Metadata Records: Measuring the Effectiveness of Various Approaches

Date: May 2015
Creator: Knudson, Ryan Charles
Description: Automatic language identification has been applied to short texts such as queries in information retrieval, but it has not yet been applied to metadata records. Applying this technology to metadata records, particularly their title elements, would enable creators of metadata records to obtain a value for the language element, which is often left blank due to a lack of linguistic expertise. It would also enable the addition of the language value to existing metadata records that currently lack a language value. Titles lend themselves to the problem of language identification mainly due to their shortness, a factor which increases the difficulty of accurately identifying a language. This study implemented four proven approaches to language identification as well as one open-source approach on a collection of multilingual titles of books and movies. Of the five approaches considered, a reduced N-gram frequency profile and distance measure approach outperformed all others, accurately identifying over 83% of all titles in the collection. Future plans are to offer this technology to curators of digital collections for use.

Convenience to the Cataloger or Convenience to the User? An Exploratory Study of Catalogers’ Judgment

Convenience to the Cataloger or Convenience to the User? An Exploratory Study of Catalogers’ Judgment

Date: May 2015
Creator: Hasenyager, Richard Lee Jr.
Description: This mixed-method study explored cataloger’s judgment through the presence of text as entered by catalogers for the 11 electronic resource items during the National Libraries test for Resource Description and Access (RDA). Although the literature discusses cataloger’s judgment and suggests that cataloging practice based on new cataloging code RDA will more heavily rely on cataloger’s judgment, the topic of cataloger’s judgment in RDA cataloging was not formally studied. The purpose of this study was to study the differences and similarities in the MARC records created as a part of the RDA National Test and to determine if the theory of bounded rationality could explain cataloger’s judgment based on the constructs of cognitive and temporal limits. This goal was addressed through a content analysis of the MARC records and various statistical tests (Pearson’s Chi-square, Fisher’s Exact, and Cramer’s V). Analysis of 217 MARC records was performed on seven elements of the bibliographic record. This study found that there were both similarities and differences among the various groups of participants, and there are indications that both support and refute the assertion that catalogers make decisions based on the constructs of time and cognitive ability. Future research is needed to be able to ...

Executive Information Seeking and the Corporate Library

Executive Information Seeking and the Corporate Library

Date: May 2015
Creator: Washburn, Adrianne J
Description: This study began with an interest in corporate libraries and a genuine curiosity in the information preferences and resources valued by executive leaders at JET Aircraft Co. Executive information preferences and the downward trend in special libraries initiated the investigation of information seeking among executive leaders and yielded the inquiry: What resources do JET Aircraft Co. executives value when they need information? Employing an ethnographic approach, this study investigated what JET Aircraft Co. executives know about information resources, what they believe about information resources, and how they act when they require information. While JET Aircraft Co. maintained a special corporate library called the Company Research Library (CRL), the purpose of this study was to determine what resources were of value to executives at JET Aircraft Co., understanding that the CRL may or may not be a resource executives’ value. As a byproduct, this study also sought to establish executive information preferences and perceptions of the CRL. Information seeking at the executive level, studied through an ethnographic lens, provided insight into how executives at JET Aircraft Co. work and what they prefer, and it established a baseline for the Company Research Library’s position among the resources valued by executives.

Patient Family and Hospital Staff Information Needs at a Pediatric Hospital: an Analysis of Information Requests Received by the Family Resource Libraries

Patient Family and Hospital Staff Information Needs at a Pediatric Hospital: an Analysis of Information Requests Received by the Family Resource Libraries

Date: May 2015
Creator: Rutledge, M. Hannah
Description: This research explored the information needs of patient families and hospital staff at a pediatric hospital system in Dallas, Texas. Library statistics recorded in four hospital libraries from 2011 - 2013 were used to analyze the information requests from patient families and hospital staff. Crosstabulations revealed the extent to which patient families and hospital staff used the libraries to satisfy their information needs. The data showed that patient families used the libraries very differently than hospital staff. Chi-square tests for independence were performed to identify the relationships between the Classification (Patient Family, Hospital Staff) and two descriptors of information needs (Request Type, Resources Used). There were a total of 1,406 information requests analyzed. The data showed that patient families and hospital staff information requests differed greatly in the number of information requests, the type of information requested, the resources used and the time the library staff spent on the requests. Chi-square analyses revealed relationships statistically significant at the p < .05 level; however, the strength of the relationships varied.

Assessing Terrorist Cyber Threats: Engineering a Functional Construct

Assessing Terrorist Cyber Threats: Engineering a Functional Construct

Access: Use of this item is restricted to the UNT Community.
Date: December 2014
Creator: Morgan, Deanne
Description: Terrorist organizations and individuals make use of the Internet for supportive activities such as communication, recruiting, financing, training, and planning operations. However, little is known about the level of computer-based (“cyber”) threat such terrorist organizations and individuals pose. One step in facilitating the examination and assessment of the level of cyber threat posed by terrorist organizations and individuals is development of an assessment tool or methodology. This tool would guide intelligence collection efforts and would support and facilitate comparative assessment of the cyber threat posed by terrorist organizations and individuals through the provision of a consistent method of assessment across time, amongst organizations and individuals, and between analysts. This study leveraged the professional experience of experts to engineer a new functional construct – a structured analytical technique designed to assess the cyber threat posed by terrorist entities and individuals. The resultant instrument was a novel structured analytical construct that uses defined indicators of a terrorist organization/individual’s intent to carry out cyber attacks, and their capability to actually do so as measures of an organization/individual’s overall level of cyber threat.

Exploring Factors That Lead to Perceived Instructional Immediacy in Online Learning Environments

Exploring Factors That Lead to Perceived Instructional Immediacy in Online Learning Environments

Date: December 2014
Creator: Spiker, Chance W
Description: Instructional communication research clearly indicates that instructor immediacy contributes significantly to effective instruction. However, the majority of immediacy studies have been conducted in traditional (face-to-face) classroom environments. More recently, instructional communication research has focused on assessing the impact of immediacy in online classroom environments. Again, immediacy appears to significantly contribute to effective instruction. The challenge is that most recent immediacy studies use immediacy measurements developed to test immediacy behaviors in face-to-face settings. Considering the lack of nonverbal communication and limited or absent synchronous or verbal communication in online instructional settings, the behaviors contributing most significantly to perceived immediacy, researchers need to reassess the immediacy construct in online environments. The present research explores and identifies behaviors reported by instructors to establish psychological closeness (i.e., immediacy) in online learning environments and assesses to what extent these behaviors are similar to or different from face-to-face immediacy-producing behaviors.
