The Effect of Information Literacy Instruction on Library Anxiety Among International Students
Access:
Use of this item is restricted to the UNT Community
This study explored what effect information literacy instruction (ILI) may have on both a generalized anxiety state and library anxiety specifically. The population studied was international students using resources in a community college. Library anxiety among international students begins with certain barriers that cause anxiety (i.e., language/communication barriers, adjusting to a new education/library system and general cultural adjustments). Library Anxiety is common among college students and is characterized by feelings of negative emotions including, ruminations, tension, fear and mental disorganization (Jiao & Onwuegbuzie, 1999a). This often occurs when a student contemplates conducting research in a library and is due to any number of perceived inabilities about using the library. In order for students to become successful in their information seeking behavior this anxiety needs to be reduced. The study used two groups of international students enrolled in the English for Speakers of other Languages (ESOL) program taking credit courses. Each student completed Bostick's Library Anxiety Scale (LAS) and Spielberger's State-Trait Anxiety Inventory (STAI) to assess anxiety level before and after treatment. Subjects were given a research assignment that required them to use library resources. Treatment: Group 1 (experimental group) attended several library instruction classes (the instruction used Kuhltau's information search …

A user's guide to Sandia's latin hypercube sampling software : LHS UNIX library/standalone version.
This document is a reference guide for the UNIX Library/Standalone version of the Latin Hypercube Sampling Software. This software has been developed to generate Latin hypercube multivariate samples. This version runs on Linux or UNIX platforms. This manual covers the use of the LHS code in a UNIX environment, run either as a standalone program or as a callable library. The underlying code in the UNIX Library/Standalone version of LHS is almost identical to the updated Windows version of LHS released in 1998 (SAND98-0210). However, some modifications were made to customize it for a UNIX environment and as a library that is called from the DAKOTA environment. This manual covers the use of the LHS code as a library and in the standalone mode under UNIX.

International initiative to engage Iraq's science and technology community : report on the priorities of the Iraqi science and technology community.
This report describes the findings of the effort initiated by the Arab Science and Technology Foundation and the Cooperative Monitoring Center at Sandia National Laboratories to identify, contact, and engage members of the Iraqi science and technology (S&T) community. The initiative is divided into three phases. The first phase, the survey of the Iraqi scientific community, shed light on the most significant current needs in the fields of science and technology in Iraq. Findings from the first phase will lay the groundwork for the second phase that includes the organization of a workshop to bring international support for the initiative, and simultaneously decides on an implementation mechanism. Phase three involves the execution of outcomes of the report as established in the workshop. During Phase 1 the survey team conducted a series of trips to Iraq during which they had contact with nearly 200 scientists from all sections of the country, representing all major Iraqi S&T specialties. As a result of these contacts, the survey team obtained over 450 project ideas from Iraqi researchers. These projects were revised and analyzed to identify priorities and crucial needs. After refinement, the result is approximately 170 project ideas that have been categorized according to …

Methods for model selection in applied science and engineering.
Mathematical models are developed and used to study the properties of complex systems and/or modify these systems to satisfy some performance requirements in just about every area of applied science and engineering. A particular reason for developing a model, e.g., performance assessment or design, is referred to as the model use. Our objective is the development of a methodology for selecting a model that is sufficiently accurate for an intended use. Information on the system being modeled is, in general, incomplete, so that there may be two or more models consistent with the available information. The collection of these models is called the class of candidate models. Methods are developed for selecting the optimal member from a class of candidate models for the system. The optimal model depends on the available information, the selected class of candidate models, and the model use. Classical methods for model selection, including the method of maximum likelihood and Bayesian methods, as well as a method employing a decision-theoretic approach, are formulated to select the optimal model for numerous applications. There is no requirement that the candidate models be random. Classical methods for model selection ignore model use and require data to be available. Examples …

Intergovernmental cooperation for mission-oriented information systems: a memoir
This frankly personal account is based on my involvement in negotiations, design, and development for international bibliographic systems to support three different missions: fostering the peaceful uses of atomic energy (International Nuclear Information System, or INIS); supporting research, development, and better practices in agriculture (International Information System for the Agricultural Sciences and Technology, or AGRIS); and improving economic and social conditions in poorer countries (Development Sciences Information System, or DEVSIS). All three designs were based on the concept of decentralized operation: each country reports the information produced in its own territory; the merging of this input and the overall management are in the hands of an organization in the United Nations system; and all participants have equal rights to exploit the entire database. INIS began in 1970 and is still in steady operation; AGRIS started in 1975 and showed quantitative and qualitative growth for more than twenty years but has been in disastrous decline since its peak in 1996; and DEVSIS, unfortunately, was not launched on a global scale. Attempts are made to identify the condition -- political and technical -- likely to favor or frustrate efforts to obtain cooperation among countries for the construction of large, essentially comprehensive databases …

Balancing Scientific Publication and National Security Concerns: Issues for Congress
There is a lack of consensus regarding the best method of balancing scientific publishing and national security. The current federal policy, as described in National Security Decision Directive 189, is that fundamental research should remain unrestricted and that in the rare case where it is necessary to restrict such information, classification is the appropriate vehicle to do so. Other mechanisms restrict international information flow, where Export Administration Regulations (EAR) and International Traffic in Arms Regulations (ITAR) control export of items and technical information on specific lists. Both EAR and ITAR contain a fundamental research exclusion, but this exclusion is lost if prepublication review of research results for sensitive information occurs.

Measures of effectiveness:an annotated bibliography.
The purpose of this report is to provide guidance, from the open literature, on developing a set of ''measures of effectiveness'' (MoEs) and using them to evaluate a system. Approximately twenty papers and books are reviewed. The papers that provide the clearest understanding of MoEs are identified (Sproles [46], [48], [50]). The seminal work on value-focused thinking (VFT), an approach that bridges the gap between MoEs and a system, is also identified (Keeney [25]). And finally three examples of the use of VFT in evaluating a system based on MoEs are identified (Jackson et al. [21], Kerchner & Deckro [27], and Doyle et al. [14]). Notes are provided of the papers and books to pursue in order to take this study to the next level of detail.

The Teaching of Children's Poetry: An Exploration of Instructional Practices in University Courses of Children's Literature, English, Language Arts, and Reading Education
There are no studies which focus on the instructional practices employed in the teaching of children's poetry at the university level. This project aimed to describe the instructional practices utilized in the teaching of children's poetry at universities across the United States. Limited to the practices of the university professors and adjunct instructors who were members of the Children's Literature Assembly (CLA) of the National Council of Teachers of English (NCTE) at the time of this study, this investigation attempted to ascertain the general perceptions of poetry held by these university professors and adjunct instructors, their in-class instructional practices, and the types of poetry assignments given. Additionally, this study revealed both the poets typically highlighted and the goals held by professors and instructors in courses of children's literature, English, language arts, library science, and reading education. A mixed-methods design provided the framework for the descriptive data gleaned from the Poetry Use Survey. Quantitative data analysis yielded descriptive statistical data (means, standard deviations, ranges, percentages). Qualitative data analysis (manual and computer-assisted techniques) yielded categories and frequencies of response. Major findings included respondents': (a) belief that the teaching of poetry was important, (b) general disagreement for single, "correct" interpretations of poetry and …

Guidelines - A Primer for Communicating Effectively with NABIR Stakeholders
This version of the communication primer comprises two interlocking parts: Pat 1, a practical section, intended to prepare you for public interactions, and Part 2, a theoretical section that provides social and technical bases for the practices recommended in Part 1. The mutual support of practice and theory is very familiar in science and clearly requires a willingness to observe and revise our prior assumptions--in this document, we invoke both. We hope that is offering will represent a step both towards improving practice and maturing the theory of practical science communication.

Wayfinding tools in public library buildings: A multiple case study.
Access:
Use of this item is restricted to the UNT Community
Wayfinding is the process of using one or more tools to move from one location to another in order to accomplish a task or to achieve a goal. This qualitative study explores the process of wayfinding as it applies to locating information in a public library. A group of volunteers were asked to find a selection of items in three types of libraries-traditional, contemporary, and modern. The retrieval process was timed and the reactions of the volunteers were recorded, documented, and analyzed. The impact of various wayfinding tools-architecture, layout, color, signage, computer support, collection organization-on the retrieval process was also identified. The study revealed that many of the wayfinding tools currently available in libraries do not facilitate item retrieval. Inconsistencies, ambiguities, obstructions, disparities, and operational deficiencies all contributed to end-user frustration and retrieval failure. The study suggests that failing to address these issues may prompt library patrons-end users who are increasingly interested in finding information with minimal expenditures of time and effort-may turn to other information-retrieval strategies and abandon a system that they find confusing and frustrating.

Matching a statistical pressure snake to a four-sided polygon and estimating the polygon corners.
Given a video image source, a statistical pressure snake is able to track a color target in real time. This report presents an algorithm that exploits the one-dimensional nature of the visual snake target outline. If the target resembles a four-sided polygon, then the four polygon sides are identified by mapping all image snake point coordinates into Hough space where lines become points. After establishing that four dominant lines are present in snake contour, the polygon corner points are estimated. The computation burden of this algorithm is of the N logN type. The advantage of this method is that it can provide real-time target corner estimates, even if the corners themselves might be occluded.

Information Needs of Art Museum Visitors: Real and Virtual
Museums and libraries are considered large repositories of human knowledge and human culture. They have similar missions and goals in distributing accumulated knowledge to society. Current digitization projects allow both, museums and libraries to reach a broader audience, share their resources with a variety of users. While studies of information seeking behavior, retrieval systems and metadata in library science have a long history; such research studies in museum environments are at their early experimental stage. There are few studies concerning information seeking behavior and needs of virtual museum visitors, especially with the use of images in the museums' collections available on the Web. The current study identifies preferences of a variety of user groups about the information specifics on current exhibits, museum collections metadata information, and the use of multimedia. The study of information seeking behavior of users groups of museum digital collections or cultural collections allows examination and analysis of users' information needs, and the organization of cultural information, including descriptive metadata and the quantity of information that may be required. In addition, the study delineates information needs that different categories of users may have in common: teachers in high schools, students in colleges and universities, museum professionals, art …

Correlation Profiles and Motifs in Complex Networks.
Networks have recently emerged as a unifying theme in complex systems research [1]. It is in fact no coincidence that networks and complexity are so heavily intertwined. Any future definition of a complex system should reflect the fact that such systems consist of many mutually interacting components. These components are far from being identical as say electrons in systems studied by condensed matter physics. In a truly complex system each of them has a unique identity allowing one to separate it from the others. The very first question one may ask about such a system is which other components a given component interacts with? This information system wide can be visualized as a graph, whose nodes correspond to individual components of the complex system in question and edges to their mutual interactions. Such a network can be thought of as a backbone of the complex system. Of course, system's dynamics depends not only on the topology of an underlying network but also on the exact form of interaction of components with each other, which can be very different in various complex systems. However, the underlying network may contain clues about the basic design principles and/or evolutionary history of the complex …

The K-selected Butcher-Oemler Effect
We investigate the Butcher-Oemler effect using samples of galaxies brighter than observed frame K* + 1.5 in 33 clusters at 0.1 {approx}< z {approx}< 0.9. We attempt to duplicate as closely as possible the methodology of Butcher & Oemler. Apart from selecting in the K-band, the most important difference is that we use a brightness limit fixed at 1.5 magnitudes below an observed frame K* rather than the nominal limit of rest frame M(V ) = -20 used by Butcher & Oemler. For an early type galaxy at z = 0.1 our sample cutoff is 0.2 magnitudes brighter than rest frame M(V ) = -20, while at z = 0.9 our cutoff is 0.9 magnitudes brighter. If the blue galaxies tend to be faint, then the difference in magnitude limits should result in our measuring lower blue fractions. A more minor difference from the Butcher & Oemler methodology is that the area covered by our galaxy samples has a radius of 0.5 or 0.7 Mpc at all redshifts rather than R{sub 30}, the radius containing 30% of the cluster population. In practice our field sizes are generally similar to those used by Butcher & Oemler. We find the fraction of …
