Library & information science literature: How much of it is research?
Authors: Turcios Mirna E. , Agarwal Naresh , Watkins Linda 
Published: January 2013

AbstractIn Library and Information Science (LIS), while there is an awareness of the variety of journal literature, we do not have a number on the percentage of the collection that qualifies as research. A content analysis of the LIS literature available at the Simmons College Library is currently in progress. The research level collection of LIS literature in support of the Graduate School of Library and Information Science (GSLIS) program at the college makes the Library an ideal candidate for this study. Research is pre‐defined and a collection method for a content analysis is planned. The entirety of the collection of articles available in 2011 will be analyzed and classified as per: 1) research versus non‐research, 2) the subject of each article, and 3) the percentage of research compared to non‐research. This study will benefit students, faculty, and staff with research requirements as well as librarians who guide patrons through a search. Further, it will provide a sense of the state of LIS literature for the sample year to be compared to previous studies.
Gender differences concerning Wikipedia: A follow‐up study
Authors: Lim Sook 
Published: January 2013

AbstractThis follow‐up study of Lim and Kwon (2010) examined whether gender differences persist in certain aspects concerning Wikipedia. Additionally, this study examined other new variables, such as satisficing (satisfying and sufficing) and peer approval in relation to gender. Data were collected using a web survey in fall 2011. A total of 123 surveys were usable for this study. The key findings show that two data sets collected three years apart were consistent with each other, demonstrating that the persistence of gender differences in college students with respect to Wikipedia use, their perceived credibility of Wikipedia, and self‐evaluation of their ability discerning the credibility of Wikipedia information. In addition, this study found that male students showed a higher level of satisficing with Wikipedia and tended to report a higher level of their peer's approval for Wikipedia than their female counterparts did. The findings call for attention to educational interventions to narrow the gender gap concerning Wikipedia or user‐generated content (UGC).
Effects of learning styles on the application of search tactics: A preliminary result
Authors: Huang Chunsheng , Joo Soohyung , Xie Iris 
Published: January 2013

AbstractIn this study, we investigated how searchers' learning styles would influence their application of search tactics. We measured searchers' learning styles including Active/Reflective and Sensing/Intuitive dimensions using Felder and Silverman's (1988) instrument. Then, based on multiple regression, the effects of learning styles on searchers' application patterns of search tactics were examined. Preliminary results of this study indicates that (1) active searchers spent more time in accessing forward tactics, (2) sensing searchers spent more time in visiting previous pages and in evaluating search results, and (3) reflective searchers spent more time in evaluating individual items.
Follow the data: How astronomers use and reuse data
Authors: Sands Ashley , Borgman Christine L. , Wynholds Laura , Traweek Sharon 
Published: January 2013

AbstractWe analyze the people and infrastructure involved in the building, sustaining, and curation of large astronomy sky surveys. Our research assesses what new infrastructures, divisions of labor, knowledge, and expertise are necessary for the proper care of data. Between May 2011‐ February 2012, we conducted fourteen interviews employing Sloan Digital Sky Survey (SDSS) data use as the focus. SDSS is a multi‐faceted, multi‐phased data‐driven telescope project with hundreds of collaborators and thousands of users of the open data. The Follow the Data interview protocol identifies a single publication authored by each interviewee and uses it as a lens looking backward and forward to identify data uses leading into and out of the publication.The interviews revealed the ways these astronomers discover, locate, retrieve, and store external data for their research. Any given astronomy research project may employ multiple methods to discover, locate, retrieve, and store multiple datasets. Our research finds that informal and formal methods are used to discover and locate data, including person‐to‐person contact. Data retrieval and storage methods are often determined by the size of the dataset and the amount of infrastructure available to the researcher. Astronomy research practices are evolving rapidly with access to more data and better tools. The poster presentation will report further on how those data are used and reused in astronomy.

Authors: Zhang Yin , Kudva Sonali 
Published: January 2013

AbstractIn recent years, several scholars have called for an ecological approach to HIB (Human information Behavior) research in order to better understand information needs and information seeking. In this poster we present the theoretical background of the ecological approach and present the findings of a study that investigates correlations between people's information needs and the information channels they seek in relation to contextual and environmental factors.
Combined methods, thick descriptions: Languages of collaboration on Github
Authors: Weber Nicholas M. 
Published: January 2013

AbstractLike many professional work activities in this age of ubiquitous computing and high‐speed internet connections, computer programming and software development are increasingly mediated by systems with ‘social media’ features like profiles, avatars, ‘liking’, and commenting capabilities. When working on shared tasks, programmers have effectively leveraged these capabilities to overcome differences in time and location while simultaneously using collaborative web applications, such as version control repositories like SCM or ‘git’ systems to work together more efficiently. Here we present preliminary findings from a project investigating patterns of collaboration on the social coding platform Github. We've used a research method that combines the use of statistical approaches from social network analysis (SNA) and traditional qualitative case study construction. Our results show that this method is useful in qualitatively explaining the topology of a collaborative network, especially the formation of cliques that have been identified using traditional SNA metrics.
Extending information quality assessment methodology: A new veracity/deception dimension and its measures
Authors: Rubin Victoria L. , Vashchilko Tatiana 
Published: January 2013

AbstractThis paper extends information quality (IQ) assessment methodology by arguing that veracity/deception should be one of the components of intrinsic IQ dimensions. Since veracity/deception differs contextually from accuracy and other well‐studied components of intrinsic IQ, the inclusion of veracity/deception in the set of IQ dimensions has its own contribution to the assessment and improvement of IQ. Recently developed software to detect deception in textual information represents the ready‐to‐use IQ assessment (IQA) instruments. The focus of the paper is on the specific IQ problem related to deceptive messages and affected information activities as well as IQA instruments (or tools) of detecting deception to improve IQ. In particular, the methodology of automated deception detection in written communication provides the basis for measuring veracity/deception dimension and demonstrates no overlap with other intrinsic IQ dimensions. Considering several known deception types (such as falsification, concealment and equivocation), we emphasize that the IQA deception tools are primarily suitable for falsification. Certain types of deception strategies cannot be spotted automatically with the existing IQA instruments based on underlying linguistic differences between truth‐tellers and liars. We propose the potential avenues for the future development of the automated instruments to detect deception taking into account the theoretical, methodological and practical aspects and needs. Blending multidisciplinary research on Deception Detection with the one on IQ in Library and Information Science (LIS) and Management Information Systems (MIS), the paper contributes to IQA and its improvement by adding one more dimension, veracity/deception, to intrinsic IQ.

Published: January 2013

AbstractPrecision and recall are two widely accepted measures to Information Retrieval (IR) system performance. Different search strategies can yield different precisions and recalls for the same IR system, search engine or website. Therefore, precision and recall can also be used to measure search strategy effectiveness. YouTube® is a popular social media website which hosts the largest number of user‐generated videos on the web. The YouTube® search engine only provides text words search function and search results are retrieved through the system matching these search terms to video descriptions, tags, comments, etc. Therefore, precision and recall can also be used to measure search strategy effectiveness. This paper aims to test if a search strategy using multiple search terms is effective by analyzing the relevance of the retrieved YouTube® videos on Smokeless Tobacco Products (STP) and YouTube® provided video usage statistics and community engagement statistics.17 search terms were used to retrieve YouTube® videos on STP which were recorded in a master file. All duplicate videos from the retrieved results were excluded. Unique videos were then selected based on pre‐defined inclusion and exclusion criteria set by the research team. A sample of 440 unique videos was randomly selected for data analysis. SPSS 19.0 was used for data analysis. Descriptive analysis, precisions and recalls, logistic regression, and odds ratio test results are reported. The study found that only a few search terms out of the total 17 terms are more effective in terms of relevance of the retrieved videos. Also, YouTube® provided video usage statistics and community engagement statistics did not have significant association with the relevance of the retrieved videos. Recommendations for potential solutions on designing more effective search strategies are provided.
Objective preoperative estimation of the ability of primary closure on anterolateral thigh free flap donor site: Circumference and area ratios of deep tissue to thigh
Authors: Song Kyeongho , Nam Subong , Choi Soojong , Kim Joohyoung , Lee Jaewoo , Bae Yongchan 
Published: January 2013

AbstractPurpose: The purpose of this study was to consider the relationship between the ratio of deep tissue including muscle to thigh at donor sites and the possibility of performing primary closure of donor site. Methods: The subjects were 74 patients who had harvesting of anterolateral thigh (ALT) free flap from June 2005 to June 2011. Primary closure was possible for 65 but not possible for 9. All received CT angiography of lower extremity before their operations. We measured circumference and cross‐sectional area of thigh and deep tissue including muscle at the reference point. Using the measured data, we examined the ratio of circumference as well as cross‐sectional area of deep tissue including muscles to thighs. Results: For whom primary closure was possible, the ratio of deep tissue including muscle's circumference to thigh's at the reference point was 0.83 ± 0.07 on average, and the ratio of cross‐sectional area was 0.68 ± 0.11. For whom primary closure was not possible, the ratio of circumference was 0.89 ± 0.06 on average, and the cross‐section areas was 0.8 ± 0.07. The average width of flap for those with primary closure was 64.9 mm and without primary closure was 84.4 mm. There was statistical significance in ratios of circumference and cross‐sectional area between primary closure and without primary closure. Conclusion: Primary closure of donor site when performing ALT free flap gets increasingly difficult as the ratio of deep tissue including muscle in the thighs increased. Such information prior to the procedure will be helpful in determining flap design and finalizing the operation plan. © 2013 Wiley Periodicals, Inc. Microsurgery, 2013.
Synthesis and electro‐optical properties of polyfluorene modified with randomly distributed electron‐donor and rotaxane electron‐acceptor structural units in the main chain
Authors: Farcas Aurica , Janietz Silvia , Harabagiu Valeria , Guegan Philippe , Aubert Pierre‐Henri 
Published: January 2013

AbstractPolyfluorene PF•γCD rotaxane copolymer, composed of randomly distributed 9,9‐dioctylfluorene, methyltriphenylamine (electron‐donating) and 9‐dicyanomethylenefluorene complexed with γ‐cyclodextrin (γCD) (electron‐accepting) structural units, has been synthesized by Suzuki cross‐coupling reaction. The chemical structures were proved by FTIR and 1H NMR spectroscopy. The surface morphology, thermal, optical, electrochemical behavior, and adhesion characteristics of the obtained rotaxane copolymer have been investigated and compared with those of the nonrotaxane counterpart (PF). Relatively high fluorescence efficiency, almost identical normalized absorbance maximum in solution and solid‐state of PF•γCD rotaxane copolymer, and a more uniform and smoother surface with lower adhesion forces provides the role of γCD encapsulation on the lower aggregation propensity. PF•γCD and PF copolymers exhibit n‐ and p‐doping processes and blue‐light emission in the film state. The optical and electrochemical band gaps (ΔEg), as well as the highest occupied molecular orbital/lowest unoccupied molecular orbital positions in an energetic diagram indicate that both copolymers are promising blue‐emitting electroluminescent materials. © 2013 Wiley Periodicals, Inc.

AbstractWe studied Au‐Pd‐Ti‐Pd ohmic contacts made by thermal evaporation of metals in vacuum onto n ‐GaN (n ‐AlN) with high dislocation density heated to a temperature of 350 °C. Temperature dependence of ohmic contacts resistivity may be described by the mechanism of current flow through the metal shunts associated with dislocations, with allowance made for current limitation by diffusion supply of electrons to the contact.

Abstract
Bullimore, R. D., Foster, N. L., and Howell, K. L. 2013. Coral-characterized benthic assemblages of the deep Northeast Atlantic: defining “Coral Gardens” to support future habitat mapping efforts – ICES Journal of Marine Science, 70: 511–522. Providing statistically robust maps of habitat distributions on which to base spatial planning and management of the marine area is reliant upon established and agreed descriptions and definitions of habitats. “Coral Gardens” is an Oslo–Paris Convention (OSPAR) listed habitat, which currently cannot be reliably mapped as a result of poorly developed deep-sea habitat classification systems and habitat definitions. The aim of this study is to assess and inform development of the current definition of this habitat to support future mapping efforts. This study uses multivariate community analysis of video data to identify deep-sea benthic assemblages characterized by coral taxa and thus constituting a potential “coral gardens” habitat. Assemblages are assessed against a set of qualifying criteria, derived from current definitions of “coral gardens”, first at the assemblage level then sample by sample. The current definition of “coral gardens” captures a range of benthic assemblages, thus “Coral Gardens” cannot be considered a single “habitat”. While 19 assemblages are identified as being characterized by one or more coral garden taxa, only 8 meet the qualifying criteria. It is suggested that the current definition incorporates descriptions of the different “Coral Gardens” assemblages together with guidance on threshold densities for coral species specific to each assemblage type.
Advancement and current status of wear debris analysis for machine condition monitoring: a review
Authors: Kumar Manoj , Shankar Mukherjee Parboti , Mohan Misra Nirendra 
Published: January 2013

PurposeThe dependency on human expertise for analysis and interpretation is the main reason for wear debris analysis not being used in industry to its full potential and becoming one of the most powerful machine condition monitoring strategies. The dependency on human expertise makes the interpretation and result subjective in nature, costly and time consuming. The purpose of this paper is to review work being done to develop an automatic, reliable and objective wear particle classification system as a solution to the above problem. At the same time it also aims to discuss some common off line test methods being practiced for wear debris analysis.Design/methodology/approachComputer image analysis is a solution for some of the problems associated with the conventional techniques. First it is tried to efficiently describe the characteristics of computer images of different types of wear debris using a few numerical parameters. Then using some Artificial Intelligence tools, the wear particle classification system can be developed.FindingsMany shape, size and surface parameters are discussed in the paper. Out of these, nine numerical parameters are selected to describe and distinguish six common type of wear debris. Once the type of debris is identified, the mode of wear and hence the machine condition can be assessed.Practical implicationsThe present process of fault and condition monitoring of an equipment by wear debris analysis involves human judgment of debris formations. A set‐up standard for comparison of debris will enable the maintenance team to diagnose faults in a comparatively better way.Originality/valueThe aim of this paper is to discuss the difficulties in identifying wear particles and finding out the exact health of equipment, which, due to its subjective nature, is influenced by human errors. An objective method with certain standards for classification of wear particles compatible with an artificial intelligence system will yield some flawless results of wear debris analysis, which has not been attempted in the past as per available literature.
Effect of different nitriding processes on the friction coefficient of 304 austenitic and 420 martensitic stainless steels
Authors: Aydin Hakan , Bayram Ali , Topçu Şükrü 
Published: January 2013

PurposeThe purpose of this paper is to present the results of a study on friction characteristics of plasma, salt‐bath and gas nitrided layers produced in AISI 304 type austenitic and AISI 420 type martensitic stainless steels.Design/methodology/approachPlasma nitriding processes were carried out with DC‐pulsed plasma in 80% N2+20% H2 atmosphere at 450°C and 520°C for 8 h at a pressure of 2 mbar. Salt‐bath nitriding was performed in a cyanide‐cyanate salt‐bath at 570°C for 1.5 h. Gas nitriding was also conducted in NH3 and CO2 atmosphere at 570°C for 13 h. Characterization of all nitrided samples has been carried out by means of microstructure, microhardness, surface roughness measurement and friction coefficient. The morphologies of the worn surfaces of the nitrided samples were also observed using a scanning electron microscope. Friction characteristics of the nitrided samples have been investigated using a ball‐on‐disc friction and wear tester with a WC‐Co ball as the counterface under dry sliding conditions.FindingsThe plasma nitrided and salt‐bath nitrided layers on the 420 steel surfaces were much thicker than on the 304 steel surfaces. However, there was no obvious and homogeneous nitrided layer on the gas nitrided samples' surface. The plasma and salt‐bath nitriding techniques significantly increased the surface hardness of the 304 and 420 samples. The highest surface hardness of the 304 nitrided samples was obtained by the plasma nitrided technique at 520°C. On the other hand, the highest surface hardness of the 420 nitrided layers was observed in the 450°C plasma nitrided layer. Experimental friction test results showed that the salt‐bath and 450°C plasma nitrided layers were more effective in reducing the friction coefficient of the 304 and 420 stainless steels, respectively.Originality/valueThe relatively poor hardness and hence wear resistance of austenitic and martensitic stainless steels needs to be improved. Friction characteristic is a key property of performance for various applications of austenitic and martensitic stainless steels. This work has reported a comparison of friction characteristics of austenitic 304 and martensitic 420 stainless steels, modified using plasma, salt‐bath and gas nitriding processes. The paper is of significances for improving friction characteristics, indirectly wear performances, of austenitic and martensitic stainless steels.

Published: January 2013

PurposeAttention deficit hyperactivity disorder (ADHD) is the most commonly studied and diagnosed psychiatric disorder in children. There is a need to engage service development, commissioning and service managers to address primary care involvement and define service models that will enable effective management of people with ADHD. The purpose of this project is to define recommendations through consensus that can be implemented to improve ADHD management in the UK.Design/methodology/approachA set of 40 consensus statements has been developed by a multidisciplinary group of ADHD professionals in the UK. These statements cover ten topics, ranging from commissioning of ADHD services to optimisation of the care pathway. The aim of the project was to define a set of standards that could be tested across a wider clinical population.FindingsA total of 122 respondents scored each statement on a questionnaire and levels of agreement were summated and analysed. Of 40 statements, only four scored less than 90 per cent agreement, with all statements achieving greater than 74.9 per cent agreement.Originality/valueRecommendations support the wider integration of ADHD services and the closer involvement of commissioners within the new GP consortia to ensure that the potentially negative societal and personal impacts of ADHD are managed effectively and with appropriate use of resources.
