The role of purpose, approach‐avoidance, self‐efficacy, intolerance of uncertainty, and locus of control in undergraduates' source selection
Authors: Williams Rachel D. , Kim Kyung‐Sun 
Published: January 2013

AbstractThe primary objective of this research study poster is to explore differences in sources selected by undergraduate students in relation to two factors: 1) purpose of search, and 2) scores on the Problem‐Solving Inventory (PSI) based on sources undergraduate students select for both course‐related and everyday‐life information‐seeking purposes. Also considered are differences in self‐efficacy, intolerance of uncertainty, and external locus of control scores reliant upon sources selected initially during a search process. Two main research questions were the focus of this study. First, what types of information sources do undergraduates tend to use first during an everyday‐life or course‐related search, and is context important? Second, do certain user characteristics influence the selection of the first source selected during information searches? A series of chi square and one tailed t tests were performed to examine these research questions in depth. The overarching goal of this research is to use these results to better understand and structure information services for undergraduates.
Effect of institutional factors on source and channel use by medical residents
Authors: Agarwal Naresh , Xu Yunjie (Calvin) , Lawrence Harrison , Agarwal Archana 
Published: January 2013

AbstractAn important question in information‐seeking behavior is how people decide on which information source to use when they need information for their work‐related tasks. This question becomes especially pertinent in light of the varying degree of legitimacy accorded to digital sources, and the use of new channels of access such as mobiles and tablets. Building upon an earlier study on source use, and using the institutional theory, this is a report of a survey‐in‐progress of medical residents in one or more Boston hospitals. The study will also examine the role of serendipity in source choice when residents encounter information when not consciously looking for it. Insights gained from the study will build on past work on information behavior and source choice, as well as the application of institutional theory to hospital settings. It will help hospitals make optimal provision of information source types based on their preference and usage by medical residents.
A novel research approach to enhance research group‐level science data management
Authors: D'Ignazio John , Qin Jian 
Published: January 2013

AbstractThis poster will report an alternative approach compared with large‐scale collection, technology development, or discipline informatics projects by exploring the enhancement of science data management at the research group level. An academic‐year‐long project involving both information and technical analysts demonstrated that flexible introduction of IT in the form of a relational database solution presents an opportunity to incorporate data‐related practices, behavior, and schemes into a tool. The project team used cognitive work analysis and participatory design research methods to sensitively analyze research practice and then design and introduce a prototype tool. Iterative analysis and design cycles captured and incorporated the complex practices of researchers who struggle with the accumulation of samples and related digital data files from years of research. Design research processes will be analyzed according to project developments and research group reaction to the proposed data management tool design and preliminary attempt at implementation.
Technical and economical assessment of voltage control strategies in distribution grids
Authors: Stetz Thomas , Kraiczy Markus , Braun Martin , Schmidt Sebastian 
Published: January 2013

ABSTRACTTechnically effective and economically efficient voltage control is a major issue in distribution systems with high amounts of installed capacity from dispersed generators, such as photovoltaic. In this paper, the results of an encompassing cost–benefit analysis for different voltage control strategies are presented. The investigated voltage control strategies comprise two different reactive power control methods and one combined reactive power/active power control method, each applied by inverters of utility scale photovoltaic systems. The results are gained by performing 12‐month root‐mean‐square simulations with a 1 min resolution, using the model of a real distribution grid as well as complex generation and load models. The simulations show that local reactive power provision methods as well as temporal active power output curtailment methods are capable of reducing the necessity of a voltage‐driven grid reinforcement. However, the economic benefit of those voltage control strategies highly depends on the parameterization of the respective control algorithm. Copyright © 2013 John Wiley & Sons, Ltd.
Toward a “Structural BLAST”: Using structural relationships to infer function
Authors: Dey Fabian , Cliff Zhang Qiangfeng , Petrey Donald , Honig Barry 
Published: January 2013

AbstractWe outline a set of strategies to infer protein function from structure. The overall approach depends on extensive use of homology modeling, the exploitation of a wide range of global and local geometric relationships between protein structures and the use of machine learning techniques. The combination of modeling with broad searches of protein structure space defines a “structural BLAST” approach to infer function with high genomic coverage. Applications are described to the prediction of protein–protein and protein–ligand interactions. In the context of protein–protein interactions, our structure‐based prediction algorithm, PrePPI, has comparable accuracy to high‐throughput experiments. An essential feature of PrePPI involves the use of Bayesian methods to combine structure‐derived information with non‐structural evidence (e.g. co‐expression) to assign a likelihood for each predicted interaction. This, combined with a structural BLAST approach significantly expands the range of applications of protein structure in the annotation of protein function, including systems level biological applications where it has previously played little role.
Temperature‐dependent conformational change affecting Tyr11 and sweetness loops of brazzein

Published: January 2013

AbstractThe sweet protein brazzein, a member of the Csβα fold family, contains four disulfide bonds that lend a high degree of thermal and pH stability to its structure. Nevertheless, a variable temperature study has revealed that the protein undergoes a local, reversible conformational change between 37 and 3°C with a midpoint about 27°C that changes the orientations and side‐chain hydrogen bond partners of Tyr8 and Tyr11. To test the functional significance of this effect, we used NMR saturation transfer to investigate the interaction between brazzein and the amino terminal domain of the sweet receptor subunit T1R2; the results showed a stronger interaction at 7°C than at 37°C. Thus the low temperature conformation, which alters the orientations of two loops known to be critical for the sweetness of brazzein, may represent the bound state of brazzein in the complex with the human sweet receptor.

Authentication with low‐cost RFID tags in mobile networks
Authors: Yen Chih‐Ta , Guo Ming‐Huang , Lo Nai‐Wei , Deng Der‐Jiunn 
Published: January 2013

ABSTRACTRecently, mobile networks and radio frequency identification (RFID) technologies are both widely applied by many enterprises to develop their applications. The third‐generation (3G) mobile network technology is one of the popular mobile network technologies because service providers can serve users anytime and anywhere through 3G mobile network technology. A solution that combines RFID technology with 3G mobile network technology could identify users anytime and anywhere. However, RFID tags are limited in computation power and suffered from security threats, especially on mobile networks. An authentication with low‐cost RFID tags in Mobile Networks should be proposed in this paper. This paper designs a key agreement mechanism to achieve consistency, integration, legality, and safety. In order to design a low‐cost scheme, our authentication mechanism is built of simple XOR operations and one‐way hash function. Although the computation cost of our proposed mechanism is not the best, our proposed mechanism can achieve more security requirements for practical applications.

Conodonts from the Niur Formation (Silurian) of the Derenjal Mountains, Central Iran
Authors: MÄNNIK P. , MILLER C. G. , HAIRAPETIAN V. 
Published: January 2013

AbstractA Llandovery to Ludlow age for the Niur Formation in the Derenjal Mountains (east-central Iran) is proposed based on new conodont data and previous work on other fossils. The uppermost part of the studied section yielded no diagnostic conodonts but may be Pridoli in age. Some intervals can be dated more precisely: Unit 11 (at least its upper part) is middle Telychian in age and corresponds to thePterospathodus amorphognathoides lennartiZone; the lowermost part of Unit 16 is earliest Ludlow in age and corresponds to theKockelella crassaZone; the uppermost Unit 16 is late Ludlow (Ludfordian) in age and corresponds to theOzarkodina snajdriInterval Zone. The Llandovery–Wenlock boundary lies between units 12 and 13 based on sedimentological evidence. The precise location of the Wenlock–Ludlow boundary in the section is not clear but lies below Unit 16. Present-day Iran was located far away from Baltica and Laurentia, on the other side of the Rheic Ocean. This ocean does not seem to have been a major migration barrier for most organisms including the conodonts.

SUMMARYMaternal filarial infection influences the risk of acquiring infection and development of immunity in children. Here we have analysed the blood samples of 60 mothers (24 infected and 36 uninfected) and their corresponding cord bloods to assess the impact of maternal infection on the anti-sheath antibodies and cytokine production in neonates born from them. About 69·4% of non-infected mothers and their cord bloods showed the presence of anti-sheath antibodies, while only 16·6% of the cord bloods from infected mothers were positive for it. The IL-10 level was significantly high in cord bloods of infected mothers compared with non-infected mothers. At the same time the IL-10 level was also observed to be remarkably high in cord bloods of both infected and non-infected mothers negative for anti-sheath antibody. In contrast, IFN-γlevels were significantly high in cord bloods of non-infected mothers compared with infected mothers and the increment was prominent in cord bloods of both infected and non-infected mothers positive for anti-sheath antibody. The study reveals that the presence or absence of anti-sheath antibodies in association with cytokines skews the filarial specific immunity to either Th1 or Th2 responses in neonates. This may affect the natural history of filarial infection in early childhood.
Procedures without borders: The language-ideological anchorage of legal-administrative procedures in translocal institutional settings
Authors: Maryns Katrijn 
Published: January 2013

AbstractTheoretical and applied research in the field of institutional discourse analysis calls for an increasing awareness of the constitutive nature of discourse in the representation and the assessment of social identities (Sarangi & Roberts 1999; Blommaert 2010; Eades 2010). The staunchly textualist accounts surviving institutional practice, however, tend to obscure complex multidiscursive and language ideologically anchored processes that mold procedural outcomes. On the basis of first-hand ethnographic data collected across legal-administrative procedures in Belgium, this article aims at revealing some meaningful contexts that have been erased in the case of an asylum seeker who became a murder victim and whose asylum file was used in the assize trial as a resource to sketch his social identity. The analysis explores the ideological functioning of textuality in the situated details of communicative practice, thereby aiming for a better understanding of the intricacies of multidiscursive identity construction in translocal procedural settings.

Low-income Housing in Chinese Cities: Policies and Practices
Authors: Huang Youqin 
Published: January 2013

AbstractThis paper argues that the low-income housing programme in China has so far failed to provide adequate housing for the poor for three main reasons: the central government's failure to define a clear mission; a lack of commitment from local governments; and an exclusionary policy towards migrants. A systematic review of low-income housing policy in China shows that the central government juggles its economic and socio-political goals thereby causing constant changes in low-income housing policy. Meanwhile, the existing public finance system, the performance evaluation system and localization in policy implementation have all resulted in a lack of commitment from local governments to low-income housing. Inadequate provision is made worse by problems with allocation. Despite encouraging changes since 2010, many factors underlying the government's failures remain unchanged, thus the fate of low-income housing remains uncertain.
Neglected infectious diseases: Are push and pull incentive mechanisms suitable for promoting drug development research?
Authors: Mueller-Langer Frank 
Published: January 2013

AbstractInfectious diseases are among the main causes of death and disability in developing countries, and they are a major reason for the health disparity between rich and poor countries. One of the reasons for this public health tragedy is a lack of lifesaving essential medicines, which either do not exist or badly need improvements. In this article, we analyse which of the push and pull mechanisms proposed in the recent literature may serve to promote research into neglected infectious diseases. A combination of push programmes that subsidise research inputs through direct funding and pull programmes that reward research output rather than research input may be the appropriate strategy to stimulate research into neglected diseases. On the one hand, early-stage (basic) research should be supported through push mechanisms, such as research grants or publicly financed research institutions. On the other hand, pull mechanisms, such as prize funds that link reward payments to the health impacts of effective medicines, have the potential to stimulate research into neglected diseases.

-Golgi network through interaction with Arf-GEF Gea2p and flippase Drs2p
Authors: Tsai Pei-Chin , Hsu Jia-Wei , Liu Ya-Wen , Chen Kuan-Yu , Lee Fang-Jen S. 
Published: January 2013

Significance
Membrane asymmetry, curvature, and dynamics have major roles in cellular processes, including vesicle transport. The GTPase ADP ribosylation factor (Arf) and a lipid translocase (flippase) are critical for membrane reorganization during vesicle formation. Direct evidence that Arf and flippase work in concert on membrane transformation/architecture is, however, lacking. We demonstrate that activated Arf-like protein Arl1 interacts with the Arf-activating guanine nucleotide-exchange factor Gea2 and flippase Drs2, forming a ternary complex that is required for lipid asymmetry and Arl1 function at the Golgi. These findings represent a previously missing piece of the puzzle that is our understanding of Arf-mediated membrane remodeling.

Published: January 2013

SignificanceMicrobial communities regulate the cycling of energy and matter in the environment, yet how they respond to environmental change is not well-known. We describe here a day in the life of wild planktonic microbial species using robotic sampling coupled with genome-wide gene expression analysis. Our results showed that closely related populations, as well as very different bacterial and archaeal species, displayed remarkably similar time-variable synchronous patterns of gene expression over 2 d. Our results suggest that specific environmental cues may elicit cross-species coordination of gene expression among diverse microbial groups, potentially enabling multispecies coupling of metabolic activity.

Authors: Chen Chuji , Shi Hongyan , Song Fumin 
Published: January 2013

PurposeThe purpose of this paper is to present a method for evaluating the structural dynamic characteristics of a flying probe tester.Design/methodology/approachThe dynamic characteristics of a flying probe tester framework were analyzed based on a finite element analysis method. First, modal analysis was carried out to characterize the modal parameters of the structure. Second, the harmonic response was analyzed according to the modal analysis and the response curve of the structural system was studied. Finally, transient analysis was conducted to obtain the transient response of the structures at the beginning of the vibration.FindingsThe natural frequency and the response frequency of a natural granite structure was the highest and the transient vibration displacement amplitude was the smallest compared with cast iron and artificial stone structures.Originality/valueA comprehensive understanding of the dynamic characteristics of the framework of a flying probe tester with three different materials has been achieved. The results of the analyses provide a reference for the framework design of a flying probe tester.
BS 11000 for health commissioning
Authors: Quayle Adrian , Ashworth David , Gillies Alan 
Published: January 2013

PurposeThe purpose of this paper is to consider how BS 11000 may be usefully deployed within a commissioning situation in the light of the Department of Health's suggestion that it represents “best practice”.Design/methodology/approachThe study uses case studies from other sectors (criminal justice) and IT outsourcing to consider the nature of the commissioning relationship at the heart of the English NHS post‐2013. It looks at how BS 11000 is intended to support business relationships and how this can address potential problems identified in the case studies.FindingsThe study finds that business relationships are often regarded in a reductionist manner based on a simple contractual relationship. The case studies suggest that a richer more collaborative business relationship is required for effective provision of services. The authors suggest that BS 11000 can help organisations put in place the foundations of such relationships.Research limitations/implicationsThe Clinical Commissioning Groups are still being formed, and the marketplace for service providers in the NHS is expanding dramatically. This means that there are limited opportunities for studying this issue in situ, and therefore it is necessary to use case studies from other domains.Practical implicationsThis study suggests that the commissioning relationship is more complex than a simple contractual relationship, and a genuine partnership is needed between the new Clinical Commissioning Groups and their providers.Social implicationsFrom 2013, the NHS is intended to be a commissioner of services rather than a provider. Effective health and social care will depend upon an effective commissioning relationship.Originality/valueThe study provides insights from related fields into an area that cannot yet be studied itself, as it is still being formed. It has access to unpublished data from an ESRC funded study to provide new insights from a related public‐sector context.
A lifecycle perspective on buyer‐supplier collaboration in process development projects
Authors: Rönnberg‐Sjödin David 
Published: January 2013

PurposeDevelopment and implementation of new process equipment within the process industries frequently necessitate strong collaboration between process firms and their equipment suppliers in joint process development projects. However, collaboration in this setting entails significant challenges over the lifecycle of these projects. Accordingly, the purpose of this article is to explore the problems and opportunities faced by equipment suppliers during collaboration with process firms, throughout the various lifecycle stages of process development projects.Design/methodology/approachThe article synthesizes results from 22 interviews in a multiple case study of eight equipment suppliers in the process industries and a comprehensive review of relevant literature to identify critical problems of opportunities during the lifecycle. In total, data were gathered from firms in six different countries.FindingsA deficient pre‐study may create problems due to miscommunication during development when close interaction is required. Purchasing discussions can be done simultaneously to development when a supplier has been selected, although uncertainty is a problem. It is important to get end‐user feedback and commitment during development and later stages. During assembly and installation and start‐up, a variety of actors are working simultaneously which requires coordination and planning from an early stage. Close interaction and education with end‐user is critical for the technology transfer in the start‐up stage. Sharing of experiences enhances operational performance during production.Research limitations/implicationsThis study contributes by employing information rich case study data to describe the problem and opportunities faced over the full lifecycle in joint process development projects in the process industry. In particular, key issues over the lifecycle have been identified and described (e.g. purchasing, start‐up, education). Moreover, the adoption of a lifecycle perspective has indicated how activities, issues, and managerial challenges in specific stages are interconnected and affect the joint work in the following stages.Practical implicationsThe findings of this article serves as guidelines to managers in equipment supplier firms and their customers by highlighting the problems and opportunities for improvement that occur during the interconnected stages of process development projects.Originality/valueBy focusing on the collaborative activities in different stages, this study higlights the critical problems and opportunities in the lifecycle of process equipment. In addition this article outlines how joint process development activities can facilitate enhanced operational performance, by means of collaborative design, installation and operation of new process equipment – i.e. “open operation”.
