Progressive information engagement model: Using, losing, and rejecting information in crisis situations
Authors: Westbrook Lynn 
Published: June 2009

AbstractThe pervasive, personal crisis of intimate partner violence (IPV) demands the full panoply of community and governmental information resources. IPV survivors must make effective use of those varied information resources but the more fully those resources are used, the more complex their information applications become. This study triangulates two populations and two data‐gathering techniques encompassing IPV survivor interactions with both formal and informal information systems. The first segment analyzed the information issues of IPV survivors in 1,793 postings from an active bulletin board (BB) community. The second segment analyzed in‐depth interviews with 57 individuals (24 shelter staff, 14 police officers, and 19 IPV survivors) in ten contrasting cities. In addition to a clearly defined matrix of information needs that are reported elsewhere, an unexpected pattern emerged which has been tentatively labeled as the “progressive information engagement model.” This four‐stage model provides significant indicators of the different qualities that determine successful information interactions at different stages in survivors' movement towards safer living. Each stage is delineated by three factors: the primary information need, the affective influences on efforts to meet that need, and the information myths that are cognitive barriers to successful information utilization. This paper explicates the stages and their characteristics.
FRBR applied to scientific data
Authors: Hourclé Joseph A. 
Published: June 2009

AbstractThe distinction between a creative work and the physical item that contains that work is clearly delineated in FRBR and other research by the Library Science community. A similar confusion exists in the scientific realm between the underlying scientific data and the digital objects that contain those data. We present a similarly scoped reference framework for sensor‐based scientific data, drawing on the concepts in FRBR, and compare it with the application of FRBR for cataloging other non‐book records.
SHARE: A superordinate online rural community
Authors: Capps Janet , Howard Sarah , McKeown Jonathan , DeMeester Karen 
Published: June 2009

AbstractComprehensive School Reform in Rural K‐8 Schools in the Southeast: Integrative Technologies for Quality Initiatives is a three‐year technology intervention funded by the US Department of Education. As part of this project, teachers in eight rural K‐8 schools in Georgia, Florida, and Alabama were given access to an online community Web‐portal built on Sakai called SHARE (Schools Helping to Advance Rural Education). This Web‐portal supports the project's goal to expand teachers' ability to access and exchange information by providing server space for each school community as well as the larger project community. Through SHARE, communities of teachers at the school level can create a new community of information exchange among all project teachers and across all project schools. The exchange at the higher project level creates a superordinate level.Data collected through multiple methods is used to make comparisons between teachers' attitudes and online information exchange practices in base‐level communities and in the larger superordinate community established through the SHARE Web‐portal. The four‐tier pyramid of Hersberger, Murray, and Rioux (2007) is used to inform the evaluation of the teachers' information sharing activities and to assist in the assessment of the overall level of gratification or discontentment of the project's community of teachers.
Exploring the information‐to‐knowledge experience of English Language Learner (ELL) students: From the cognitive, behavioral and affective perspectives
Authors: Kim Sung Un 
Published: June 2009

AbstractThis study seeks to understand the information‐to‐knowledge experience of English Language Learner (ELL) students in a Guided Inquiry project undertaken by the school librarian and subject teachers. As a pilot study, it provides an in‐depth examination of two Korean 11th grade students in a biology class of a high school in New Jersey. During the project, data were collected through questionnaire, surveys, search journal, search sessions, observation, students' papers, and semi‐structured interviews. The findings of this study will contribute to understanding of how ELL students experience information search and knowledge building through a complex research project in English so that school environments, including school libraries, can provide meaningful instructional and service interventions for them.
An investigation of image users across disciplines: A model of image needs, retrieval and use
Authors: Beaudoin Joan 
Published: June 2009

AbstractThis study investigates the image behaviors of twenty‐four participants in four separate user groups (six in each group: archaeologists, architects, art historians and artists). These groups of participants were chosen due to their heavy reliance on images to perform their daily work routines. Two of the image user groups, archaeologists and art historians, are expected to need images for pedagogical and research purposes while the two remaining groups, architects and artists, are believed to need images for inspiration and problem‐solving aims. Additionally, the inclusion of these groups of image users will allow for an assessment of image users' behaviors by discipline and underlying needs. This study will identify the critical characteristics of users' image needs, retrieval and use and these characteristics, in turn, will be used to develop a theoretical model to explain users' image behaviors.
Assessing and adapting Drupal content management system as a digital library application
Authors: Moore Tony A. 
Published: June 2009

AbstractDSpace (http://www.dspace.org/) and Greenstone (http://www.greenstone.org/) are the two leading digital library software applications. While these applications are wildly adopted they are not flexible enough to provide more robust interactivity. Web2.0 technologies are not explicitly changing how individuals interact with information. The changes we see are related to what this class of technologies are enabling. I believe, and this poster will show that coupled with digital libraries, this class of technologies stimulates knowledge creation. CANDDIL is a work in progress that has been designed and developed to illustrate my argument. In this paper I present the findings from an assessment and initial adaptation of Drupal, an open source content management system for the purposes of serving as a digital library. This report presents the current state of CANDDiL and its potential for advancing digital library research.
When digital objects change — exactlywhatchanges?
Authors: Renear Allen H. , Dubin David , Wickett Karen M. 
Published: June 2009

AbstractFormal accounts of digital objects often characterize them asbit strings, graphs, sets, tuples, relations,or other similar constructs from discrete mathematics. Such characterizations imply that these objects cannot undergo changes such as losing or gaining parts, or having their parts rearranged. Yet our discourse about digital objects seems, if taken literally, to imply that those objects routinely undergo such changes. One strategy for dealing with this inconsistency is to affirm an account which leaves digital objects immutable and re‐locates change in the persons interacting with these objects.
Coherent knowledge structure and theory‐based approach to categorization
Authors: Assefa Shimelis 
Published: June 2009

AbstractHow we understand our surroundings is an age old question. The general understanding is that it is through concepts, categories, and relations that we make sense of our world. This study presents a result of a dissertation that attempted to investigate the nexus between human cognition of concepts/categories and the knowledge structure in the unified medical language system (UMLS). In contrast to the classical account that views category as structures organized in terms of similarity, this study takes a new approach that explains categories as structures organized around theories. The findings reveal that humans largely use simplified rules, definition type descriptions, and naïve explanations as bases for categorization judgment (coherence criteria). These explanations research participants used to characterize their category formation, after a careful text analysis, created meaningful and coherent interrelationships when plotted in a visual link chart. The performance of the cognitive task also showed a remarkable difference between those with subject background and those without. Using the least restrictive notion of ‘distance’ as a function of relatedness, this study also showed a significant correspondence between human conceptual map (based on the cognitive performance) and the knowledge structure in the UMLS, as shown by the goodness‐of‐fit coefficient.
Finding and providing context online
Authors: Buckland Michael K. , Larson Ray R. , Shaw Ryan 
Published: June 2009

AbstractKnowing the context and relationships involved makes the difference between seeing and understanding. In a print environment the reference collection of the library provides a carefully constructed environment of auxiliary resources well‐designed for exploring context. In the digital environment the need for an easily‐used, well‐stocked, well‐organized reference collection has been neglected. We report on a project to demonstrate techniques to enable anyone to easily use reliable sources to find the background for topics, places, events, institutions, and persons encountered in online reading of biographical texts and journals on Irish culture and history.
Babies in bathtubs: Public views of private behaviors represented in the Flickr domain
Authors: Kramer‐Duffield Jacob , Hank Carolyn 
Published: June 2009

AbstractPublishing personal content online raises issues of openness, access and privacy. While these issues have been treated in the literature, a substantial subset is youth‐oriented, typically focusing on the potential for negative outcomes from such disclosure and youths' presumed lack of awareness of the consequences of their publication activities. Recent research suggests, however, that adults also demonstrate a lack of discretion in their own publication activities. Through examining a particular class of content ‐ adult publication of photos depicting “babies in bathtubs,” and other candid and bare moments, to Flickr, a Web‐based photo sharing and management application ‐ this study aims to quantify and describe issues of openness, access and privacy to raise awareness that these issues are not limited to generational distinctions, by 1) characterizing images across multiple topical domains from two contextual perspectives, contributor and user, and 2) identifying associations between these image characteristics and contributor behaviors and profiles. The primary assumption motivating this research exercise is that online indiscretion is a youth problem, but in fact, it is broader than that; the collective “we” are all subject to failing to meet the assumed societal norms for deliberate or accidental privacy and discretion when publishing personal content to the Web.
A model of information needs of end‐users (MINE) in the electronic information environment
Authors: Kebede Gashaw , Rorissa Abebe 
Published: June 2009

AbstractLibrary and information science researchers have given due attention to the study of and modeling of information needs. However, there is a need for a model that captures the essence of information needs of end‐users as a combination of both content and non‐content (e.g. those related to information resources and end‐users' skills) and the fact that information needs vary according to the information environment in which they occur. Toward this end, we proposed a model of information needs of end‐users (MINE) in the electronic information environment where the nature of “user tasks”, the state of the “electronic information resources”, and the level of “user experience” with the existing electronic information resources give rise to users' “information needs”. The poster will present the setting for the model and state hypotheses regarding interrelationships between the constructs.
Building an integrated model of information behavior through information journals
Authors: Narayan Bhuva , Spink Amanda 
Published: June 2009

AbstractInformation behavior models generally focus on one of many aspects of information behavior, either information finding, conceptualized as information seeking, information foraging or information sense‐making, information organizing and information using. This ongoing study is developing an integrated model of information behavior. The research design involves a 2‐week‐long daily information journal self‐maintained by the participants, combined with two interviews, one before, and one after the journal‐keeping period. The data from the study will be analyzed using grounded theory to identify when the participants engage in the various behaviors that have already been observed, identified, and defined in previous models, in order to generate useful sequential data and an integrated model.
A multi‐case study analysis of indigenous knowledge programs in the United States
Authors: Srikantaiah Deepa 
Published: June 2009

AbstractThe impacts of colonization and modernization have undermined and neglected indigenous knowledge, not only in current day developing countries, but also for select communities in industrialized or developed countries. Over the last decade, however, there has been an increased international interest to revitalize and restore indigenous knowledge. Multilateral development organizations, local and global NGOs, policymakers, education institutions and the private sector, such as pharmaceutical industries, are among the institutions that have shown interest in indigenous knowledge.For instance, indigenous knowledge has shown to be of great importance in health and development practices. In Southern Africa, the Commercial Products from the Wild (CPWild) project estimates the value of informal herbal remedies to be between $75 million to $150 million per year in the market. Over 1000 indigenous crops and medicinal plants are traded in this informal market system and more than 100,000 people are income earners in this industry.The international interest shown by these institutions, however, has led to numerous challenges for indigenous knowledge at the global level, and sparked many debates around the nature of indigenous knowledge, who the indigenous knowledge holders are, and whether these knowledge systems are scientifically valid or applicable in conventional knowledge paradigms.This paper presents findings from a multi‐case study analysis of indigenous knowledge programs or initiatives in three institutions ‐ the World Bank, the National Institutes of Health, and Pennsylvania State University. In each case study the identification, collection, and institutionalization processes used for indigenous knowledge were studied to understand how indigenous knowledge is represented alongside conventional knowledge.
Past futures and technoscientific innovation: The mutual shaping of science fiction and science fact
Authors: Fleischmann Kenneth R. , Templeton Thomas Clay 
Published: June 2009

AbstractThis study explores the relationship between science fiction and science and engineering. Building on the concept of the mutual construction of technoscience and society from the field of science and technology studies and the concept of the book in the life of the reader from the field of library and information science, the study traces the potential influence of science fiction on the career choices and research trajectories of scientists and engineers. This paper reports preliminary findings from interviews with twelve scientists and engineers at the NASA Goddard Space Flight Center. Salient themes emerging from the interviews include science fiction as a a first exposure to science, as an escape from the mundane aspects of everyday life, and as a tool that helps scientists to frame their work. Overall, it appears that, while scientists and engineers reject the notion that science fiction has a completely deterministic impact on their career choices and research trajectories, there definitely appears to be some kind of relationship between an inclination toward the practice of science and the appeal of science fiction. Future research directions may include a broad‐scale survey and educational efforts specifically focused on information science and technology.

AbstractWe describe a prototype for a multilingual semantic interface to the academic programs of a university. Navigating within a graph model of the academic disciplines and fields, the users are led to course and program documents. For core academic concepts, informational support is provided by language specific links to Wikipedia. The web‐based prototype is currently evaluated in a user study.
Technology use in meetings: Information handling & polychronicity
Authors: Kleinman Lisa 
Published: June 2009

AbstractThe proliferation of portable information technologies (e.g. laptops and mobile phones) along with the increasing availability of wireless networks allows individuals to expand and extend their information environment. One context which has been impacted by these changes is the workplace; individuals now multitask in face‐to‐face meetings with other technologies. This multitasking can have a dual impact: the information needs of the face‐to‐face group may be better met by increased access to networked information, but the individuals in the group using the technology may decide to use it for non‐group tasks, which may be disruptive and/or diminish the individual's focus away from the team. In this pilot research, the concepts of information handling and polychronicity (a preference for multitasking) are used to explore qualitative data from interviews with 15 office workers.
Hydroxytyrosol inhibits the proliferation of human colon adenocarcinoma cells through inhibition of ERK1/2 and cyclin D1

Published: June 2009

AbstractExtra virgin olive oil is rich in phenolic compounds which are believed to exert beneficial effects against many pathological processes, including the development of colon cancer. We show that one of the major polyphenolic constituents of extra virgin olive oil, hydroxytyrosol (HT), exerts strong antiproliferative effects against human colon adenocarcinoma cells via its ability to induce a cell cycle block in G2/M. These antiproliferative effects were preceded by a strong inhibition of extracellular signal‐regulated kinase (ERK)1/2 phosphorylation and a downstream reduction of cyclin D1 expression, rather than by inhibition of p38 activity and cyclooxygenase‐2 (COX‐2) expression. These findings are of particular relevance due to the high colonic concentration of HT compared to the other olive oil polyphenols and may help explain the inverse link between colon cancer and olive oil consumption.

AbstractResveratrol (RSV) is classified as a phytoestrogen due to its ability to interact with estrogen receptors (ERs). We assessed structure–activity relationships of RSV and the analogs 4,4′‐dihydroxystilbene (4,4′‐DHS), 3,5‐dihydroxystilbene (3,5‐DHS), 3,4′‐dihydroxystilbene (3,4′‐DHS), 4‐hydroxystilbene (4‐HS) using as model systems the ERα‐positive and negative MCF7 and SkBr3 breast cancer cells, respectively. In binding assays and transfection experiments RSV and the analogs showed the following order of agonism for ERα: 3,4′‐DHS > 4,4′‐DHS > 4‐HS > RSV, while 3,5‐DHS did not elicit any ligand properties. Computational docking analysis and real‐time PCR revealed for each analog a distinct ERα binding orientation and estrogen target gene expression profile. Interestingly, the aforementioned order of ligand activity was confirmed in proliferation assays which also showed the lack of growth stimulation by 3,5‐DHS. Our data suggest that subtle changes in the structure of the RSV derivatives examined may be responsible for the different ERα‐mediated biological responses observed in estrogen‐sensitive cancer cells.
Role of inertia in falling head permeability test
Authors: Kaczmarek Mariusz 
Published: June 2009

AbstractThis paper discusses the role of macro‐ and micro‐inertial forces in the falling head permeability test. The model of flow including viscous and dynamic interaction forces is formulated. Then, the model is used to perform numerical simulations of the tests for high‐permeability soils. The presented results prove the existence of a level of permeability of materials above which macro‐and micro‐inertial forces are important and that in all cases the latter forces are dominant. The results suggest limited validity of the standard interpretation of the falling head permeability test and possible usefulness of the test to determine both permeability and the parameter characterizing non‐linear interactions of fluid and solid skeleton.

Published: June 2009

AbstractA 16‐year‐old male presented with a 3‐month history of an asymptomatic, enlarging conjunctival lesion. An excisional biopsy was performed and histologic and immunohistochemical examination showed characteristic features of a peripheral primitive neuroectodermal tumour (PNET) adjacent to a benign compound naevus. FISH analysis, demonstrating a split‐signal at 22q12, confirmed the diagnosis. Staging investigations were negative confirming the primary nature of the lesion. The patient was treated with local wide re‐excision and chemotherapy. He remains alive and well 29 months after initial resection. Pediatr Blood Cancer 2009;53:669–671. © 2009 Wiley‐Liss, Inc.
