Male body movements as possible cues to physical strength: A biomechanical analysis
Authors: McCarty Kristofor , Hönekopp Johannes , Neave Nick , Caplan Nick , Fink Bernhard 
Published: January 2013

ObjectivesComparative research suggests that male courtship displays signal condition‐dependent traits tofemales; these displays might also provide cues to potential male competitors. Although some associations betweenhuman movements and physical/behavioral qualities have been found, such research has typically only been conducted from a perspective of female mate choice. Here, using advanced motion capture and biomechanical analyses, we examine the extent to which male dancing provides cues about the dancer's physical qualities to both males and females.MethodsThirty men aged 19–37 were recorded using motion‐capture technology as they danced to a standard rhythm. Participants also completed a vascular fitness test, assessments of upper‐ and lower‐body strength, and biomechanical indices were extracted from their dance movements. Dance clips were converted into virtual humanoid characters (avatars) and rated by 27 women and 21 men on perceived dance quality.ResultsGeneral linear mixed modeling revealed that both handgrip strength and arm movements of the dancer were statistically significant predictors of dance quality ratings; stronger males who displayed larger, more variable, and faster movements of their arms being rated as better dancers. There was no effect of the sex of the observer in predicting dance quality ratings, indicating that male and female observers rated dance quality equivalently. Physical fitness was not associated with perceived dance quality.ConclusionsMen and women are able to derive certain quality cues from observing male dance movements in the form of controlled stimuli. Thus, male dancing may form a condition‐dependent ornament of certain aspects of mate quality. Am. J. Hum. Biol. 25:307–312, 2013. © 2013 Wiley Periodicals, Inc.
A Diacetylene‐Containing Wedge‐Shaped Compound: Synthesis, Morphology, and Photopolymerization
Authors: Rosenthal Martin , Li Lei , Hernandez Jaime J. , Zhu Xiaomin , Ivanov Dimitri A. , Möller Martin 
Published: January 2013

AbstractA novel wedge‐shaped compound containing two diacetylene tails, namely, methyl 3,5‐bis(trideca‐2,4‐diyn‐1yloxyl)benzoate (DDABM), was synthesized. As shown by UV/Vis spectroscopy this compound can be polymerized under UV irradiation. The crystalline structure of DDABM was investigated by grazing‐incidence wide‐angle X‐ray diffraction on oriented crystalline films deposited on PTFE‐rubbed silicon wafer substrates. Furthermore, the spherulites formed in thicker films were analyzed by wide‐angle X‐ray diffraction. A molecular packing model of DDABM based on the X‐ray diffraction data is proposed. The diacetylene units are oriented along a defined lattice direction with a reticular distance of 4.85 Å, which fulfills the requirements for topochemical polymerization. It was observed that UV polymerization does not affect the phase behavior of the compound, but mainly alters its optical properties.
Preparation of microporous activated carbon from Aegle marmelos fruit shell by KOH activation
Authors: Gottipati Ramakrishna , Mishra Susmita 
Published: January 2013

AbstractActivated carbon (AC) is well‐known for its unique properties; hence, the search for new precursors and the investigation of new methods for the preparation of AC is still drawing attention of many researchers. In the present work, microporous AC was prepared from Aegle marmelos fruit shell (AMFS) by potassium hydroxide (KOH) activation. The effect of process parameters such as impregnation ratio, carbonisation temperature and holding time on porous characteristics was investigated. The porous characteristics of prepared AC samples were analysed by N2 adsorption–desorption isotherms, and it was found that the isotherms obtained resemble typical microporous solids (Type‐I). The Langmuir surface area and total pore volume of the sample prepared at optimum conditions were found to be 937 m2/g and 0.33 cm3/g, respectively. The contribution of micropores to the porous characteristics of the prepared AC is very much appreciable, and about 97% of the total surface area and pore volume is attained by micropores. Pore size distribution (PSD) by Dubinin–Astakhov (DA) and micro‐pore (MP) methods confirmed the presence of micropores to a great extent with insignificant mesoporosity. © 2013 Canadian Society for Chemical Engineering
Michael Additions in Aqueous Media: “On‐Water” and “In‐Water” Processes from α‐Nitro Ketones and Their Anions
Authors: Giorgi Giorgio , López‐Alvarado Pilar , Miranda Sonia , Rodriguez Jean , Menéndez J. Carlos 
Published: January 2013

AbstractA variety of α,β‐unsaturated aldehydes and ketones gave very high‐yielding Michael addition reactions with α‐nitrocycloalkanones in water, at room temperature without added catalyst. These can be considered as one of the very few “on‐water” Michael reactions known in the literature, because they took place in suspension or emulsion and at increased speed relative to the same transformations performed in organic solvents. A related protocol that uses very dilute, aqueous solutions of potassium carbonate as the reaction media extended the scope of the method to cyclic enones and unsaturated esters, nitriles and sulfones and is likely to take place in the bulk of the aqueous phase, i.e., “in‐water”. Both preparative methods constitute environmentally benign and efficient alternatives to previously known procedures.
The evolution of information behavior research: Looking back to see the future
Authors: Given Lisa M. , Julien Heidi , Case Donald 
Published: January 2013

AbstractThis panel will examine past, present and future trends for one of the central bodies of research within information science – human information behavior (HIB). Beginning with a brief history of the settings, populations, methodologies, theories and other key features of HIB research, the panel will then explore possibilities for the future. Attendees will engage in an interactive ‘working session’ exploring the key research questions being addressed (or that should be addressed) in HIB research, as well as trends in methods and techniques that will inform future work. The panelists have received numerous grants for research on human information behavior, have published widely on the topic, and have served as research leaders within the discipline. They are all very engaging speakers, having presented at numerous international conferences and symposia. These panelists are well‐placed to facilitate an engaging discussion of trends in this important research area of the discipline.

Published: January 2013

AbstractThe theme of this year's ASIS&T conference inspires us to examine our past, present, and future as a discipline. This panel adopts a similar lens but focuses specifically on the decade that has passed since the events of 9/11 and the subsequent legislative and policy impacts on information. The aim is to provide information professionals and scholars with an open forum to critically reflect on the post 9/11 legislation, policies, and practices and how these have affected access to information and informational activities more generally, including the production, management, and diffusion of public information. With an eye toward the future, we examine the extent to which the discourses and practices of the past decade have contributed to shaping and reshaping our information environment, how the information field has responded in the ten years since this defining event, and why and how information professionals ought to remain engaged in these matters in the future.
Time and space in collaborative information seeking: The clash of effectiveness and uniqueness
Authors: González‐Ibáñez Roberto , Haseki Muge , Shah Chirag 
Published: January 2013

AbstractCollaboration takes place at different time‐space conditions. Past research has shown that these two dimensions may have different implications in the collaboration process, as well as on its outcomes, depending upon the task being performed. In collaborative information seeking (CIS), as a relatively new topic in information science, little is known about the effects of different temporal‐spatial contexts. To address this, we conducted a user study involving 80 participants in 40 pairs, which were assigned to four experimental conditions, namely: co‐located, remotely located with text chat, remotely located with audio chat, and asynchronous. Using quantitative methods, we investigated the effects of these conditions on communication, information synthesis, productivity, and user experience. Results regarding the space dimension suggest that information seeking behaviors of co‐located users tend to overlap thus affecting their coverage of diverse and useful information. Conversely, when team members are remotely located, limited interaction allows them to work more independently, leading them to explore more diverse and useful information with the added value of less cognitive and affective load. With respect to the time dimension, we found that asynchronous collaboration enables participants to reach high levels of independency at the cost of effectiveness. These results provide practical implications about how various spatial‐temporal contexts in CIS could influence factors such as productivity, efficiency, effectiveness, and uniqueness.
Accessibility and management of information sources in contexts: A case study among research engineers
Authors: Musnik Noémie , Ricard Benoit 
Published: January 2013

AbstractAssuming that workplace significantly affects information seeking and information management patterns, this study explores accessibility and management of information sources among a group of research engineers. The study analyses how these engineers, who belong to the R&D entity of a major energy group, require, search and manage information sources in given professional contexts. Furthermore, it strives to identify the contextual factors that shape information practices. This empirical study is based on a qualitative approach: following exploratory inquiries, semi‐structured interviews and observations were conducted with 15 actors in their proper workplace. Our integration within the team facilitated the participant observation stance. The study provides an analytic cartography of the various components of the organizational and informational environments whereby the activities and tasks of the above mentioned actors take place. A wide range of practices has been identified via interviews but also through the activities and work rhythms observed. An appreciative methodological framework is currently developed to analyze the practices of access to information produced and used; it underlines the contextual factors that may become driving dimensions to support an innovative perspective on information management structures. The study attempts to provide an innovative approach for the analysis of information practices in contexts, oriented toward the design of a facetted and collaborative information management system.
Old data, new scheme: An exploration of metadata migration using expert‐guided computational techniques
Authors: Mitchell Erik , McCallum Carolyn 
Published: January 2013

AbstractThis paper explores the evaluation of metadata quality within the context of migration to new conceptual models. While metadata quality and interoperability are commonly studied areas, few studies have explored the issues introduced when migrating metadata to models that require a re‐definition of metadata record to resource relationships. In order to explore this issue, this study asks the question “How do human and computational techniques compare with regards to the creation of FRBR work‐sets from existing bibliographic metadata?” The study compared cataloger assessment of FRBR relationships in a selection of 848 MARC records with automatically generated work‐sets. The Levenhstein edit‐distance algorithm was used to identify work‐sets in the automated approach. The comparison found that an improved version of work‐set keys from the OCLC FRBR algorithm provided the highest match rate with 62% of keys matching perfectly and 87% of correct work‐sets showing an 80% or higher similarity rate. The study methodology and evaluative measure overall indicate that a hybrid expert/automated approach and an improved key generation algorithm are effective alternatives to manual or automated approaches alone.
Information as exclusion: Towards a critical understanding of everyday life
Authors: Smith Harrison 
Published: January 2013

AbstractThis paper seeks to critique the theoretical components of everyday life information seeking through an exogenous incorporation of the sociology of everyday life. In particular, it focuses on the way in which everyday life spaces are increasingly being produced and sustained by practices of surveillance in order to structure information users into geo‐demographic typologies of information consumers. The argument advanced is that an analysis of the production of space can enable a more theoretically solid groundwork for understanding the relationship between information users and the social contexts of everyday information seeking.
Image similarity as assessed by users: A quantitative study
Authors: Tirilly Pierre , Mu Xiangming , Huang Chunsheng , Xie Iris , Jeong Wooseob , Zhang Jin 
Published: January 2013

AbstractImage retrieval systems are generally based on the notion of image similarity: they compute similarity scores between the images of the database and a query (image or text), and organize the images according to these scores. However, this notion is ill‐defined, and the collections used to train and evaluate image retrieval systems are based on similarity judgments that rely on simplistic, non‐realistic, assumptions. This paper addresses the issue of the definition of image similarity, and more precisely the two following questions: do humans assess image similarity in the same way? Is it possible to define reference similarity judgments that would correspond to the perception of most users? An experiment is proposed, in which human subjects are assigned two tasks that fall in principle to the system: rating the similarity of images and ranking images according to a reference image. The data provided by the subjects is analyzed quantitatively to the light of the two aforementioned questions. Results show that the subjects do not have collective strategies of similarity assessment, but that a satisfying consensus can be found individually on the data samples used in the experiments. Based on this, methods to define reference similarity scores and rankings are proposed, that can be used on a larger scale to produce realistic ground truths for the evaluation of image retrieval systems. This study is a first step towards a general, realistic, definition of the notion of image similarity in the context of image retrieval.

Published: January 2013

AbstractIn this paper, we describe a study‐in‐progress aimed at evaluating and improving the quality of online deliberation. We analyze the use of rationales in article deletion discussions on Wikipedia. Our preliminary findings suggest that the majority of participants in these discussions were concerned with the notability and credibility of the topics, and for the most part presented cogent rationales based on established site policies.
Identifying factors of online news comments
Authors: Williamson Jeanine , Christopher Eaker P.E. , Lounsbury John 
Published: January 2013

AbstractBawden and Robinson (2009) state: “[t]here is no single generally accepted definition of information overload. The term is usually taken to represent a state of affairs where an individual's efficiency in using information in their work is hampered by the amount of relevant, and potentially useful, information available to them.” (pp. 182‐183) We concentrate on the subjective dimension of information overload, defining it as: distress associated with the perception that there is too much information. We utilize psychometric scale development procedures to measure information overload and correlate it with demographic and psychological variables. Our poster reports preliminary findings that information overload is correlated significantly with gender (being female); age and year in college (positively); and measures of life satisfaction (negatively).
Groups in Mendeley: Owners' descriptions and group outcomes
Authors: Jeng Wei , He Daqing , Jiang Jiepu , Zhang Yang 
Published: January 2013

AbstractUsing four factors borrowed from traditional social group theories, we examined owners' group descriptions in Mendeley to study the applicability of traditional social group theories for large, loosely‐formed online groups. We manually annotated the descriptions for 529 Mendeley groups, and correlated the appearances of the factors with two measures of the groups' outcomes: the changes in the numbers of group members and the changes of the articles shared within the groups between 2011 and 2012. Our results suggest that, in general, all four factors are important in online groups, which indicates the usefulness of traditional group theories in the study of online groups. In addition, although a majority of the factors have helped the growth of group size being higher than average increase, several factors have caused the increase of the shared articles within the groups to be smaller than average increase.
Moving courses online as a catalyst of pedagogical innovation: An activity theory‐based view
Authors: Khanova Julia 
Published: January 2013

AbstractThe poster illustrates the use of Activity Theory as an analytical tool for study of pedagogical innovation. This exploration is based on the in‐depth study of the process of converting several face‐to‐face courses to online teaching format in the context of one university. Data from interviews with participants in different roles in the process is analyzed using the activity theory framework. The study findings suggest that exposure to online teaching technologies and methods can act as a catalyst of pedagogical innovation. The poster also illustrates the utility of activity theory for examination of the dynamic processes mixing pedagogy and technology in the complex contexts of higher education institutions.
Application of radio frequency identification technology for the study of information‐seeking behavior of public library users: Preliminary analysis
Authors: Sugie Noriko 
Published: January 2013

AbstractThis study examines the possibility of applying radio frequency identification (RFID) technology as a method to collect quantitative data on library user behavior, and thus determine common features. An innovative method of users observation was conducted at Chiyoda Public Library in 2012. Each user was asked to carry an antenna to receive the radio waves emitted from RFID tags, and a personal digital assistant (PDA) to record the data, and went about using the library as usual. RFID tags attached to books and magazines were used to identify the locations of users. Data was obtained on the time spent in the library, travel distance, traveling path, time spent browsing in each zone and time spent browsing books by subject. It was found that the users who spent less than 30 minutes in the library made up the largest percentage of these groups, while some users spent more than 2 hours. It was also found that users tended to browse general books more than other materials.
Homage to Helen Brownson: Information science pioneer
Authors: Jayroe Tina J. 
Published: January 2013

AbstractHelen Brownson (1917–) was a federal government employee from 1941–1970 and was responsible for many scientific events, technologies, and foundational aspects which fostered the transformation of the field of documentation into the field of information science. As Program Director for Scientific Documentation at the National Science Foundation's Office of Scientific Information, Brownson published dozens of reports and articles pertaining to information‐handling, scientific communication, and machine‐translation problems. She presented at and reported on international conferences and would allocate federal grant money toward pioneering projects—all in order to develop better methods for access, storage, and retrieval of recorded scientific information. She was responsible for identifying and supporting the Cranfield Experiments and founded the Annual Review of Information Science and Technology (ARIST) as well as the two technical systems publications which precipitated the need for an annual review. This poster is a concise history of Brownson's career taken directly from the forthcoming article, A Humble Servant: The Work of Helen L. Brownson and the Early Years of Information Science Research. More specifically, it is an opportunity to showcase many of the personal, historical, visual images collected during personal interviews with, and through scholarly research on this influential pioneer.
Can you relate? A study of user perceptions of thesaural subject relationships
Authors: Clarke Rachel Ivy , Lee Jin Ha 
Published: January 2013

AbstractThis poster describes a pilot study investigating what, if any, associative thesaural relationships are identifiable and distinguishable to information seekers. Using associative relationships from the Library of Congress Subject Headings (LCSH), we asked potential library users via Amazon Mechanical Turk to identify six narrower distinctions of established associative relationship types. Preliminary results from the survey indicate that some associative relationship types, such as near synonym and agent/process, are indeed identifiable, while others, like position in time and space, remain problematic.
L.A. meta (data): Exploring vocabulary interoperability in libraries, Archives and Museums
Authors: Mitchell Erik , Srikantaiah T. Kanti 
Published: January 2013

AbstractThis poster session reports the examination of user tasks in the context of domain specific vocabulary interoperability. Two vocabularies, Library of Congress Subject Headings and the Art and Architecture thesaurus, were selected for comparison using a single user task (Cross‐vocabulary discovery). Analyzing the structure of the vocabularies in the context of this task found challenges associated with the differences in concept representation, differences in vocabulary structures and varying levels of specificity. The exploration found that the similarities in structure and semantics for these two vocabularies provide a solid foundation for both user‐determined on demand and automatically derived interoperability in the context of the cross‐vocabulary discovery task. The exploration of AAT and LCSH vocabularies also found that considering the impact on stakeholders (e.g., end users, vocabulary creators, vocabulary implementers) is important when considering how to design and implement vocabulary interoperability applications.
