    2010-02-01

    The contribution then discusses briefly two recent innovative regional water projects, both located in the East Netherlands: a retention basin project on the river Vecht and the planning of a new channel, the Breakthrough. It further analyses strategies pursued by 'boundary spanners' and integrates the analysis with that of a focus group workshop and interviews held with Dutch boundary spanners working for Dutch regional Water Management Boards. The cases show that it is preferable to apply boundary spanning strategies earlier rather than later, and that opponents are also aware of this option.

    Eye-movement experiments suggest that the perceptual span during reading is larger than the fixated word, asymmetric around the fixation position, and shrinks in size contingent on the foveal processing load. We used the SWIFT model of eye-movement control during reading to test these hypotheses and their implications under the assumption of graded parallel processing of all words inside the perceptual span. Specifically, we simulated reading in the boundary paradigm and analysed the effects ...

  2. Technical Knowledge, Cultural Practices and Social Boundaries: Wan-Nan Scholars and the Recasting of Jesuit Astronomy, 1600-1800

    Science.gov (United States)

    Chu, Ping-Yi.

    Taking four Wan-nan Confucian scholars--Yang Kuang -hsien, Mei Wen-ting, Chiang Yung and Tai Chen--as examples, this dissertation studies how an immigrant Jesuit scientific community built and defended itself in a specialized institutional niche located at the Ch'ing court and how a defeated Chinese scientific tradition successfully survived by occupying a broader cultural space, with the Manchu emperor in between. Special attention is paid to how these four Confucian scholars constructed social boundaries between the Chinese and the Westerners in their astronomical discourses and how they domesticated Western astronomy in order to fit the Chinese cultural conditions situated in the power structure built by the Manchus. This inquiry begins with a brief introduction of Wan-nan and the Wan-nan school. I then discuss how the Jesuits legitimated their knowledge during the Ming -Ch'ing transition, and how Jesuit astronomy was situated within the power nexus between the Confucian literati and the emperors. The next chapter focuses on Yang Kuang-hsien and his challenges to the Jesuits. I examine his strategies and the power structure in which Yang carried out his challenge to the Jesuits. The fourth and fifth chapters investigate how Mei Wen-ting restructured the relationship between Confucianism and astronomy. The former chapter focuses on Mei's social networking and his ambivalence towards the Ming and Ch'ing dynasties, on the one hand, and towards Chinese and Western learning on the other. The latter chapter deals with how Mei Wen-ting recast Chinese astronomical tradition and Confucianism. In the sixth chapter, I will compare the fame of Chiang Yung and Tai Chen in order to demonstrate how astronomy was practiced in evidential studies after Mei Wen-ting, and how evidential studies itself conveyed an ideological construction of the other.

    Increasing role complexity has intensified the work of managers in supporting healthcare teams. This study examined the influence of front-line managers' characteristics and scope of responsibility on teamwork. Scope of responsibility considers the breadth of the manager's role. A descriptive, correlational design was used to collect cross-sectional survey and administrative data in four acute care hospitals. A convenience sample of 754 staff completed the Relational Coordination Scale as a measure of teamwork that focuses on the quality of communication and relationships. Nurses (73.9%), allied health professionals (14.7%) and unregulated staff (11.7%) worked in 54 clinical areas, clustered under 30 front-line managers. Data were analyzed using hierarchical linear modelling. Leadership practices, clinical support roles and compressed operational hours had positive effects on teamwork. Numbers of non-direct report staff and areas assigned had negative effects on teamwork. Teamwork did not vary by span, managerial experience, worked hours, occupational diversity or proportion of full-time employees. Large, acute care teaching hospitals can enable managers to foster teamwork by enhancing managers' leadership practices, redesigning the flow or reporting structure for non-direct reports, optimizing managerial hours relative to operational hours, allocating clinical support roles, reducing number of areas assigned and, potentially, introducing co-manager models.

  6. Spanning Boundaries in an Arizona Watershed Partnership: Information Networks as Tools for Entrenchment or Ties for Collaboration?

    Full Text Available The need to develop successful collaborative strategies is an enduring problem in sustainable resource management. Our goal is to evaluate the relationship between information networks and conflict in the context of collaborative groundwater management in the rapidly growing central highland region of Arizona. In this region, water-management conflicts have emerged because of stakeholders’ differing geographic perspectives and competing scientific claims. Using social network analyses, we explored the extent to which the Verde River Basin Partnership (VRBP, which was charged with developing and sharing scientific information, has contributed to collaboration in the region. To accomplish this, we examined the role that this stakeholder partnership plays in reinforcing or overcoming the geographic, ideological, expert, and power conflicts among its members. Focusing on information sharing, we tested the extent to which several theoretically important elements of successful collaboration were evidenced by data from the VRBP. The structure of information sharing provides insight into ways in which barriers between diverse perspectives might be retained and elucidates weaknesses in the partnership. To characterize information sharing, we examined interaction ties among individuals with different geographic concerns, hierarchical scales of interest, belief systems (about science, the environment, and the role of the partnership, and self-identified expertise types. Results showed that the partnership’s information-sharing network spans most of these boundaries. Based on current theories of collaboration, we would expect the partnership network to be conducive to collaboration. We found that information exchanges are limited by differences in connection patterns across actor expertise and environmental-belief systems. Actors who view scientists as advocates are significantly more likely to occupy boundary-spanning positions, that appear to impede

  8. Spanning boundaries and creating strong patient relationships to coordinate care are strategies used by experienced chronic condition care coordinators.

    Science.gov (United States)

    Ehrlich, Carolyn; Kendall, Elizabeth; Muenchberger, Heidi

    2012-08-01

    People with complex chronic conditions frequently need to navigate their own way through and around a fragmented and siloed health care system. Care coordination is a defining principle of primary care and is frequently proposed as a solution to this problem. However, care coordination requires more time and effort than primary care physicians alone have the capacity to deliver. Although registered nurses (RNs) are skilled team members who can be included in the delivery of coordinated patient care, any model of care coordination that involves RNs needs to fit within the existing health care delivery system. In this study, which used qualitative techniques based on grounded theory and included face-to-face interviews and open coding and theoretical sampling until data saturation was achieved, and which was one component of a larger action research study, we aimed to gain an understanding of the difference between usual chronic condition care and the work of chronic condition care coordination. The researchers interviewed general practitioners and RNs from various general practice sites who were actively coordinating care. Four unique processes were found to define care coordination implementation, namely: (1) moving beyond usual practice by spanning boundaries; (2) relationship-based care; (3) agreed roles and routines among relevant parties; and (4) committing to chronic condition care coordination. The findings suggested that existing professional and organisational cultures required negotiation before care coordination could be integrated into existing contexts. The challenge, however, seems to be in acknowledging and overcoming professional practice boundaries that define existing care through reflective practice and shared resourcing.

  10. Importance of titanohematite in detrital remanent magnetizations of strata spanning the Cretaceous-Paleogene boundary, Hell Creek region, Montana

    Science.gov (United States)

    Sprain, Courtney J.; Feinberg, Joshua M.; Renne, Paul R.; Jackson, Mike

    2016-03-01

    Intermediate composition titanohematite, Fe2-yTiyO3 with 0.5 ≤ y ≤ 0.7, is seldom the focus of paleomagnetic study and is commonly believed to be rare in nature. While largely overlooked in magnetostratigraphic studies, intermediate titanohematite has been identified as the dominant ferrimagnetic mineral in an array of Late Mesozoic and early Cenozoic Laramide clastic deposits throughout the central United States. Intermediate titanohematite is ferrimagnetic and has similar magnetic properties to titanomagnetite, except its unique self-reversing property. Due to these similarities, and with detrital remanent magnetizations masking its self-reversing nature, intermediate titanohematite is often misidentified in sedimentary deposits. Past studies relied upon nonmagnetic techniques including X-ray diffraction and electron microprobe analysis. While these techniques can identify the presence of intermediate titanohematite, they fail to test whether the mineral is the primary recorder. To facilitate the identification of intermediate titanohematite in sedimentary deposits, we characterize this mineral using low-temperature magnetometry and high-temperature susceptibility experiments, and present a new identification technique based on titanohematite's self-reversing property, for sediments that span the Cretaceous-Paleogene boundary (Hell Creek region, Montana). Results from the self-reversal test indicate that the majority of remanence is held by minerals that become magnetized parallel to an applied field, but that intermediate, self-reversing titanohematite (y = 0.53-0.63) is an important ancillary carrier of remanence. While earlier literature suggests that intermediate titanohematite is rare in nature, reanalysis using specialized rock magnetic techniques may reveal that it is more abundant in the rock record, particularly within depositional basins adjacent to calc-alkaline volcanics, than previously thought.

    The Williston Basin arguably contains the richest terrestrial record of faunal, floral, and paleoenvironmental change across the Cretaceous-Paleogene boundary. In the northwestern Williston Basin, the dominantly fluvial Hell Creek (Cretaceous) and Tullock (Paleocene) formations have yielded prolific dinosaur and mammalian fossil records. Unfortunately, discerning trends in both biotic and environmental evolution in this interval is challenging because regional correlations are hampered by rapid lateral facies transitions. A relative chronostratigraphic scheme based on coal beds has been employed for decades but is problematic because assumptions of lateral continuity and time-correlativity are unproven in many cases and demonstrably incorrect in some. Virtually all of the coal beds, however, preserve volcanic ashes that can be used as a chronotratigraphic scheme and for regional correlations. We currently recognize more than 40 distinct ashes in the ~200 m composite thickness of these two formations. The ashes are commonly less than 1 cm thick and as many as nineteen have been found in a single ~1.5 m coal bed. The ashes thus provide a robust basis for high-resolution regional correlations. Original glass shards in the ashes are ubiquitously altered to clays, hence conventional tephrochemical characterization is impossible. Instead we are performing electron microprobe analysis of feldspar and titanite, using major and selected trace elements. Phase compositional data are subjected to principal component analysis (PCA) and combined with geochronological data, two-feldspar thermometry (where applicable), phase presence/absence data, paleomagnetic polarity, and relative stratigraphic position to yield a matrix that allows discrimination of many of these ashes. The resulting chronostratigraphy will enable regional correlations with age resolution better than the ~10 ka best case afforded by 40Ar/39Ar dating. Results thus far clearly show that correlations of

They are subject to a rigid screening and the pressured imposed upon them may bring out a stressful experience that can affect their daily activities. The perceived social psychological academic economic and bureaucratic stressors were identified using the descriptive inferential method among the 203 scholars for school year 2013- 2014.Findings revealed that scholars are highly stressed with peoples high expectations on them as scholars and with various assignment imposed to them as scholars. Moreover scholars are stressed of fear of losing their scholarship. T-test shows that there is no significant difference on the stressors experienced by both the academic and non-academic scholars and so as to their coping mechanism. The proposed Stress Coping Mechanism Guide will help them to manage their stressors.

    2010-01-01

    Bibliometric and usage-based analyses and tools highlight the value of information about scholarship contained within the network of authors, articles and usage data. Less progress has been made on populating and using the author side of this network than the article side, in part because of the difficulty of unambiguously identifying authors. I briefly review a sample of author identifier schemes, and consider use in scholarly repositories. I then describe preliminary work at arXiv to implement public author identifiers, services based on them, and plans to make this information useful beyond the boundaries of arXiv.

  2. Google Scholar Versus Metasearch Systems

    CERN Document Server

    Sadeh, Tamar

    2006-01-01

    At the end of 2004, Google launched the beta version of a new service, Google Scholar, which provides a single repository of scholarly information for researchers. Will this service replace metasearch systems? Metasearch systems are based on just-in-time processing, whereas Google Scholar, like other federated searching systems, is based on just-in-case processing. This underlying technology, along with Google Scholar's exceptional capabilities, accords Google Scholar a unique position among other scholarly resources. However, a year after its beta release, Google Scholar is still facing a number of challenges that cause librarians to question its value for scholarly research. Nevertheless, it has become popular among researchers, and the library community is looking for ways to provide patrons with guidelines for the most beneficial manner of using this new resource. Metasearch systems have several advantages over Google Scholar. We anticipate that in the foreseeable future, libraries will continue to provid...

    Although many observers have advocated the reform of the scholarly publishing system, improvementsto functions like peer review have been adopted sluggishly. We argue that this is due to the tightcoupling of the journal system: the system's essential functions of archiving, registration,dissemination, and certification are bundled together and siloed into tens of thousands of individualjournals. This tight coupling makes it difficult to change any one aspect of the system, choking outinnovati...

    Full Text Available When Weber analyzed Judaism as part of his series concerning global religious practices and the economic arrangements that accompanied them, he decided to employ the term “pariah” as an analytic device, but without any of the pejorative connotations which are attached to the word today. Had he used instead Gastvolk (guest people throughout his book rather than “pariah-people,” many subsequent scholars would not have objected to Ancient Judaism in the way they have over the last 90 years. Arnaldo Momigliano, probably the greatest classical historian of the mid-20th century, respected Weber’s work, but also took exception to his use of “pariah” regarding Judaism. This article investigates this troubling term and the scholarship that it inspired.

    There are several good reasons you might want to read about uniform spanning trees, one being that spanning trees are useful combinatorial objects. Not only are they fundamental in algebraic graph theory and combinatorial geometry, but they predate both of these subjects, having been used by Kirchoff in the study of resistor networks. This article addresses the question about spanning trees most natural to anyone in probability theory, namely what does a typical spanning tree look like?

    Currently boundary spanning behavior is a hot topic in team research field, which involves phenomena at two levels (team level and individual level). Compared to team level, employee’s boundary spanning has not been well discussed yet. In addition, few studies have systematically explored its outcomes and impact mechanism in Chinese context. This study aimed to address the above gaps by examining whether, when and how employee’s boundary spanning behavior impacted his or her task performance. Specifically, integrating culture and social network theory into boundary spanning field, this study theorized that boundary spanning behavior led to centrality of the employee’s social network, and in turn enhance his or her task behavior. At the same time, team’s collectivism climate moderated the above path. The participants were recruited from 17 companies in two high-tech parks located in Beijing and Tianjin, China. We invited 135 team leaders and their subordinates to participate the survey, after collecting 2 wave longitudinal data sets and dropping out invalid questionnaires, responses from 61 team leaders and 292 team members were valid finally. To get enough whole network data, we purposely chose teams with small size. All measurements were (or adapted from) well-established scales. Employee’s boundary spanning behavior, centrality, and collectivism were collected at time 1, and after 8 weeks, employees’ task performance was collected at time 2. Confirmatory factor analyses showed satisfactory model fit indices. Inter-rated agreement (Rwg) and intra-class correlation (ICC) value justified the aggregation of team collectivism climate. HLM were applied to test our hypotheses since this is a cross-level research. Variables like age, education, gender, tenure and collectivism orientation at individual level, and team size at group level were controlled for. The results showed that centrality of the social network positively mediated the relation between

    Full Text Available Learning the process of scholarly writing, including the significance of peer review, is an essential element in the preparation of students for professional practice. This descriptive research study, using Scholarship of Teaching and Learning methodology, explores one approach to teaching scholarly writing in an occupational science/occupational therapy curriculum. The writing assignment was designed to offer multiple points for feedback and revision and instructional features to reinforce learning. A survey of students [n = 169] participating in this scholarly writing project was conducted yearly to gather their perceptions of learning. The results revealed four key elements: instructional strategies are needed to support scholarly writing, students value explicit instructor feedback, a successful writing experience opens the possibility for students to write in their professional future, and students will develop the habits of a writer given structure and pedagogical considerations in the assignment construction. This experience shows students will work to achieve the expected standard for scholarship once writing is made an essential part of the course and their efforts are supported by scaffolding the assignment. Through this experience, it was also learned students need opportunities for repetition and practice to refine scholarly writing. Suggestions for future research are proposed.

All these systems are relatively new, and all are still changing. They all share a common goal: to provide their users with access to the literature relevant to their specific needs. To achieve this each system responds to actions by the user by displaying articles which the system judges relevant to the user's current needs. Recently search systems which use particularly sophisticated methodologies to recommend a few specific papers to the user have been called "recommender systems". These methods are in line with the current use of the term "recommender system" in computer science. We do not adopt this definition, rather we view systems like these as components in a larger whole, which is presented by the scholarly information systems themselves. In what follows we view the recommender system as an aspect of the entire information system; one which combines the massive memory capacities of the machine with the cognitive abilities of the human user to achieve a human-machine synergy.

  2. Life Span Developmental Approach

    Full Text Available The Life Span Developmental Approach examines development of individuals which occurs from birth to death. Life span developmental approach is a multi-disciplinary approach related with disciplines like psychology, psychiatry, sociology, anthropology and geriatrics that indicates the fact that development is not completed in adulthood, it continues during the life course. Development is a complex process that consists of dying and death. This approach carefully investigates the development of individuals with respect to developmental stages. This developmental approach suggests that scientific disciplines should not explain developmental facts only with age changes. Along with aging, cognitive, biological, and socioemotional development throughout life should also be considered to provide a reasonable and acceptable context, guideposts, and reasonable expectations for the person. There are three important subjects whom life span developmental approach deals with. These are nature vs nurture, continuity vs discontinuity, and change vs stability. Researchers using life span developmental approach gather and produce knowledge on these three most important domains of individual development with their unique scientific methodology.

    1996-01-01

    An investigation has been conducted in the NASA Langley 14- by 22-Foot Subsonic Tunnel in order to further the development of semi-span testing capabilities. A twin engine, energy efficient transport (EET) model with a four-element wing in a takeoff configuration was used for this investigation. Initially a full span configuration was tested and force and moment data, wing and fuselage surface pressure data, and fuselage boundary layer measurements were obtained as a baseline data set. The semi-span configurations were then mounted on the wind tunnel floor, and the effects of fuselage standoff height and shape as well as the effects of the tunnel floor boundary layer height were investigated. The effectiveness of tangential blowing at the standoff/floor juncture as an active boundary-layer control technique was also studied. Results indicate that the semi-span configuration was more sensitive to variations in standoff height than to variations in floor boundary layer height. A standoff height equivalent to 30 percent of the fuselage radius resulted in better correlation with full span data than no standoff or the larger standoff configurations investigated. Undercut standoff leading edges or the use of tangential blowing in the standoff/ floor juncture improved correlation of semi-span data with full span data in the region of maximum lift coefficient.

    CERN. Geneva; Van de Sompel, Herbert

    2007-01-01

    Usage data is increasingly regarded as a valuable resource in the assessment of scholarly communication items. However, the development of quantitative, usage-based indicators of scholarly impact is still in its infancy. The Digital Library Research & Prototyping Team at the Los Alamos National Laboratory's Research library has therefore started a program to expand the set of usage-based tools for the assessment of scholarly communication items. The two-year MESUR project, funded by the Andrew W. Mellon Foundation, aims to define and validate a range of usage-based impact metrics, and issue guidelines with regards to their characteristics and proper application. The MESUR project is constructing a large-scale semantic model of the scholarly community that seamlessly integrates a wide range of bibliographic, citation and usage data. Functioning as a reference data set, this model is analyzed to characterize the intricate networks of typed relationships that exist in the scholarly community. The resulting c...

    2009-01-01

    Unprecedented technological advancements have radically changed the way we communicate and, at the same time, are effectively transforming science into e-Science. In turn, this transformation calls for an evolution in scholarly communication. This review describes several innovations, spanning the last decades of scholarly communication in High Energy Physics: the first repositories, their interaction with peer-reviewed journals, a proposed model for Open Access publishing and a next-generation repository for the field. We hope that some of these innovations, which are deeply rooted in the highly-interconnected and world-wide flavour of the High-Energy Physics community can serve as an inspiration to other communities.

  3. Counting spanning trees in graphs

    OpenAIRE

    Azarija, Jernej

    2012-01-01

    The history of counting the number of spanning trees dates back into the year 1842 in which the German mathematician Gustav Kirchhoff derived a relation between the number of spanning trees of a graph G (τ(G)) and the determinant of a specific submatrix associated with G. After this result many other related results followed. For example in 1889 the British mathematician A. Cayley showed that the complete graph on n nodes has nn−2 spanning trees.The function τ can nowadays be found in the fi...

  11. Thermodynamics and life span estimation

    International Nuclear Information System (INIS)

    In this study, the life span of people living in seven regions of Turkey is estimated by applying the first and second laws of thermodynamics to the human body. The people living in different regions of Turkey have different food habits. The first and second laws of thermodynamics are used to calculate the entropy generation rate per unit mass of a human due to the food habits. The lifetime entropy generation per unit mass of a human was previously found statistically. The two entropy generations, lifetime entropy generation and entropy generation rate, enable one to determine the life span of people living in seven regions of Turkey with different food habits. In order to estimate the life span, some statistics of Turkish Statistical Institute regarding the food habits of the people living in seven regions of Turkey are used. The life spans of people that live in Central Anatolia and Eastern Anatolia regions are the longest and shortest, respectively. Generally, the following inequality regarding the life span of people living in seven regions of Turkey is found: Eastern Anatolia < Southeast Anatolia < Black Sea < Mediterranean < Marmara < Aegean < Central Anatolia. - Highlights: • The first and second laws of thermodynamics are applied to the human body. • The entropy generation of a human due to his food habits is determined. • The life span of Turks is estimated by using the entropy generation method. • Food habits of a human have effect on his life span

  12. Life Span and Resiliency Theory: A Critical Review

    Directory of Open Access Journals (Sweden)

    Alexa Smith-Osborne

    2007-05-01

    Full Text Available Theories of life span development describe human growth and change over the life cycle (Robbins, Chatterjee, & Canda, 2006. Major types of developmental theories include biological, psychodynamic, behavioral, and social learning, cognitive, moral, and spiritual, and those influenced by systems, empowerment, and conflict theory. Life span development theories commonly focus on ontogenesis and sequential mastery of skills, tasks, and abilities. Social work scholars have pointed out that a limitation of life span and other developmental theory is lack of attention to resilience (Greene, 2007; Robbins et al., 1998. The concept of resilience was developed to “describe relative resistance to psychosocial risk experiences” (Rutter, 1999b, p. 119. Longitudinal studies focused on typical and atypical child development informed theory formulation in developmental psychopathology (Garmezy & Rutter, 1983; Luthar, Cichetti,& Becker, 2000 and in an evolving resilience model (Richardson, 2002; Werner & Smith, 1992. Research on resilience has found a positive relationship between a number of individual traits and contextual variables and resistance to a variety of risk factors among children and adolescents. More recently, resilience research has examined the operation of these same factors in the young adult, middle-age, and elder life stages. This article examines the historical and conceptual progression of the two developmental theories—life span and resiliency—and discusses their application to social work practice and education in human behavior in the social environment.

  16. Open Access Scholarly Publications as OER

    2013-06-01

    Full Text Available This paper presents the rationale, common practices, challenges, and some personal anecdotes from a journal editor on the production, use, and re-use of peer-reviewed scholarly articles as open educational resources (OER. The scholarly and professional discourse related to open educational resources has largely focused on open learning objects, courseware, and textbooks. However, especially in graduate education, articles published in scholarly journals are often a major component of the course content in formal education. In addition, open access journal articles are critical to expanding access to knowledge by scholars in the developing world and in fostering citizen science, by which everyone has access to the latest academic information and research results. In this article, I highlight some of the challenges, economic models, and evidence for quality of open access journal content and look at new affordances provided by the Net for enhanced functionality, access, and distribution.In the 17 years since I graduated with a doctorate degree, the climate and acceptance of open access publishing has almost reversed itself. I recall a conversation with my PhD supervisor in which he argued that publishing online was not a viable option as the product would not have permanency, scholarly recognition, or the prestige of a paper publication. His comments reflect the confusion between online resources and those described as open access, but as well illustrate the change in academic acceptance and use of open access products during the past decade. The evolution from paper to online production and consumption is a disruptive technology in which much lower cost and increased accessibility of online work opens the product to a completely new group of potential users. In the case of OER these consumers are primarily students, but certainly access to scholars from all parts of the globe and the availability to support citizen science (Silvertown, 2009

    The reconfiguration of indigenous innovation capability is an emergency issue for emerging economy. However, the 'complementary or substitution' argument about the relationship among search strategies existed in re-cent studies, which hinders the reconfiguration of indigenous innovation capability. Thus, based on data from 376 high-tech enterprises, this paper employed cluster analysis and multi-logistic regression method to study the rela-tionship between boundary spanning knowledge search synergy and types of indigenous innovation capability du-ring its reconfiguration process. There are several important results. Firstly, there are three dominant types of tech-nological innovation capability during each stage of capability reconfiguration: a) knowledge assimilation capability dominant type; b) knowledge assimilation and integration capability lead type; c)knowledge assimilation, integration capability and creation capabilities at a high level under balanced development type. Secondly, there are different boundary spanning knowledge search synergy strategies facilitate each type of indigenous innovation capability du-ring its reconfiguration. This paper not only extends the application of synergy theory, landscape theory in the field of indigenous innovation, but also has managerial implications for enterprise indigenous innovation capability reconfiguration under emerging economy.%转型中的中国,亟需企业自主创新能力的重构。针对此领域三个研究缺口,结合知识结构视角,基于376家高技术企业数据,研究知识搜寻跨边界协同对自主创新能力不同结构类型的选择机理,检验在引发自主创新能力各结构类型形成过程中,知识搜寻之间是否和如何存在跨边界互补行为,带来协同效应。进而得到若要实现自主创新能力的重构,知识搜寻应该如何变化的对策。对自主创新能力进行了聚类分析,揭示其三种结构类型:知识同化能力

    Full Text Available This article shows part of the results of a research project: The Impact of Social Change in Higher Education Staff Professional Life and Work (Spanish Ministry of Science and Innovation, SEJ2006-01876. The main aim of this project was to explore and understand how scholars establish a dialogue, resist, adapt themselves or adopt changes, in the process of constructing their professional identities. As the members of the research team were scholars ourselves, teaching and carrying out research in Spanish universities, we started this research by writing our own autoethnographies. As a result, we developed nine autoethnographies which give a complex and in-depth account of senior and junior scholars' journeys into their process of constructing their professional identity and working lives in a rapidly changing world. This article starts by giving a context to the research project and arguing the need for conducting autoethnographies. It goes on to discuss the process itself of writing autoethnographies in the context of a given research project. We then refer to the topics which have a bearing on how we have learnt to become scholars: our experience as university students, the beginning of the academic career, relationships with others, and the consequences of the mark of gender. We conclude with the lessons learnt around the dilemmas on writing autoethnographies.

    Most people have experienced loneliness and have been able to overcome it to reconnect with other people. In the current review, we provide a life-span perspective on one component of the evolutionary theory of loneliness-a component we refer to as the reaffiliation motive (RAM). The RAM represents the motivation to reconnect with others that is triggered by perceived social isolation. Loneliness is often a transient experience because the RAM leads to reconnection, but sometimes this motivation can fail, leading to prolonged loneliness. We review evidence of how aspects of the RAM change across development and how these aspects can fail for different reasons across the life span. We conclude with a discussion of age-appropriate interventions that may help to alleviate prolonged loneliness.

Cost-effective and innovative learning delivery solutions are now available from sophisticated information and communication technologies such as the Internet. In 1998, the Capability Development System (CDS) was developed by KeySpan as an on-line training system. It comprised a software assessment tool, a number of skills profiles for different occupations, and a curriculum registry providing technical information on the gas processing industry. E-learning initiatives are focused on specific projects or business units in order to better manage the training outcomes. The e-learning experience of KeySpan has resulted in benefits such as: better support to its customers and clients' needs through focused training on company-critical processes, services, products, and functions; more efficient employees; and, employees that feel part of the team.

    2004-01-01

    Scholarly writing is a critical skill for faculty in academic medicine; however, few faculty receive instruction in the process. We describe the experience of 18 assistant professors who participated in a writing and faculty development program which consisted of 7 monthly 75-minute sessions embedded in a Collaborative Mentoring Program (CMP). Participants identified barriers to writing, developed personal writing strategies, had time to write, and completed monthly writing contracts. Participants provided written responses to open-ended questions about the learning experience, and at the end of the program, participants identified manuscripts submitted for publication, and completed an audiotaped interview. Analysis of qualitative data using data reduction, data display, and conclusion drawing/verification showed that this writing program facilitated the knowledge, skills, and support needed to foster writing productivity. All participants completed at least 1 scholarly manuscript by the end of the CMP. The impact on participants' future academic productivity requires long-term follow-up.

  1. The role of gender in scholarly authorship

    West, Jevin D; King, Molly M; Correll, Shelley J; Bergstrom, Carl T

    2012-01-01

    Gender disparities appear to be decreasing in academia according to a number of metrics, such as grant funding, hiring, acceptance at scholarly journals, and productivity, and it might be tempting to think that gender inequity will soon be a problem of the past. However, a large-scale analysis based on over eight million papers across the natural sciences, social sciences, and humanities re- reveals a number of understated and persistent ways in which gender inequities remain. For instance, even where raw publication counts seem to be equal between genders, close inspection reveals that, in certain fields, men predominate in the prestigious first and last author positions. Moreover, women are significantly underrepresented as authors of single-authored papers. Academics should be aware of the subtle ways that gender disparities can appear in scholarly authorship.

    2011-01-01

    Although electronic publishing has became mainstream, to a large extent the patterns of scholarly communication are still very similar to what we knew prior to the invention of the World Wide Web. Indeed, the most common method used by authors remains writing up the findings of research in an article to be published in a scholarly journal. Many communities want to make the next step, and CERN is acting as a hub in this change.   At the end of June, more than 250 librarians, IT engineers and information specialists from different communities and from all five continents gathered at the University of Geneva to participate in the CERN Workshop on Innovations in Scholarly Communication. Will nano-publications and triplets replace the classic journal articles? Will Mendeley become the new Facebook for scientists? Why do fewer than 10% of scientists, across all disciplines, publish their work in Open Access while actually 90% think Open Access would be beneficial for their field? These were the kind of...

Kroth, Philips and Eldredge have written a commentary that gives an overview of the conference, and introduces us to the research papers that were presented. As well, two research presentations from the conference appear in this issue, an article by Donahue about a potential new method of communicating between scholars, and a paper by Gilliland in our Using Evidence in Practice section, detailing a library’s Open Access Day preparations.Kroth, Philips and Eldredge note that “The EBSCC brought together librarians and information specialists to share evidence-based strategies for developing effective local scholarly communication support and training and, hopefully, form new coalitions to address this topic at a local and national level.” (p 108. This conference focused on translational medicine, and looked at how to promote new methods of scholarly communication, partially through the inclusion of research papers at the conference.The inclusion of these articles and the evidence based focus of the EBSCC conference, made me ask myself, can scholarly communication be evidence based? At its core, scholarly communication is anything but a scientific issue. It is charged with emotion; from authors, publishers, librarians and others involved in the business of publishing. The recent shift to look at new models of scholarly communication has been a threat to many of the established models and sparked much debate in the academic world, especially in relation to open access. In her 2006 EBLIP commentary on evidence based practice and open access, Morrison notes, “Open Access and evidence based librarianship are a natural combination” (p. 49, and outlines her perspective on many of the reasons why. Debate continues to rage, however, regarding how authors should

  18. Beyond Author-Centricity in Scholarly Editing

    Directory of Open Access Journals (Sweden)

    Hans Walter Gabler

    2012-03-01

    Full Text Available Authorship – authority – authorisation – the author – the author’s will – the author’s intention: these form a cluster of notions whose validity for scholarly editing I fundamentally question. Taking measure from a historical survey of the discipline’s principles and practice from their institution under the dominance of stemmatics up to their main present-day ‘author orientation’ (Shillingsburg 1996, I see the need to split the terms ‘author’ and ‘authorship’ into a pragmatic versus a conceptual aspect. What textual scholarship engages with, directly and tangibly, is not authors but texts (and equally not works but texts, materially inscribed in transmissions. In the materiality and artifice of texts, ‘authoriality’ is accessible conceptually only, in a manner analog-ous to the Foucauldian ‘author function’. Under such premises, as well, ‘authority’, ‘authorisation’ and ‘authorial intention’ become recognisable as exogenous to texts, not integral to them. Consequently, I propose to abandon ‘authority’, ‘authorisation’ and ‘authorial intention’ as overriding principles and arbiters in editorial scholarship. Scholarly editing instead should re-situate itself in relation to texts, to textual criticism, to literary criticism and to literary theory alike, and do so by re-focussing the method-ology of its own practice. It should relinquish the external props termed ‘authorised document’, ‘textual authority’, or ‘authorial intention’ hitherto deferred to. Instead, it should revitalise skills fundamental to inherited editorial scholarship, namely those of critically assessing, and of editorially realising, textual validity. To re-embed editorial scholarship in literary criticism and theory, moreover, the interpretative and hermeneutic dimensions of textual criticism and scholarly editing will need to be freshly mapped.

  20. Cottrell Scholars Collaborative -- Integrating Research and Teaching

    Science.gov (United States)

    Sinova, Jairo

    2013-03-01

    Higher education reform needs to move towards a more interactive and integrated model, in which there is greater curricular emphasis in skill development, multi-discipline integration, and innovative connectivity, rather than traditional content driven curricula. This is even more crucial in STEM education, given our current slow down relative to other countries and the need to remain competitive in a global environment. Successful reforms require a seamless integration of research and teaching where education excellence and research excellence are not viewed by faculty as a zero sum game but as mutually benefitting ingredients of academic success. Cottrell scholars are selected among top ranking young academics with an equal passionate commitment to research excellence and education. Recently, these national group of academics sponsored by the Research Corporation for Science Advancement have created the Cottrell Scholars Collaborative (CSC) which aims at creating a self-supporting group that promotes integration of research and teaching at a national level with different initiatives. I will describe in these talk the aim of this group and the different sponsored projects that CSC is undertaking and the types of collective and individual efforts that are making a difference in sustainable education reform.

    Bar-Ilan, Judit; Peters, Isabella; Priem, Jason; Shema, Hadas; Terliesner, Jens

    2012-01-01

    Traditionally, scholarly impact and visibility have been measured by counting publications and citations in the scholarly literature. However, increasingly scholars are also visible on the Web, establishing presences in a growing variety of social ecosystems. But how wide and established is this presence, and how do measures of social Web impact relate to their more traditional counterparts? To answer this, we sampled 57 presenters from the 2010 Leiden STI Conference, gathering publication and citations counts as well as data from the presenters' Web "footprints." We found Web presence widespread and diverse: 84% of scholars had homepages, 70% were on LinkedIn, 23% had public Google Scholar profiles, and 16% were on Twitter. For sampled scholars' publications, social reference manager bookmarks were compared to Scopus and Web of Science citations; we found that Mendeley covers more than 80% of sampled articles, and that Mendeley bookmarks are significantly correlated (r=.45) to Scopus citation counts.

    Full Text Available The journal is fundamental to formal scholarly communication. This research reports highlights and preliminary findings from an empirical study of scholarly electronic journals. The purpose of the research is to assess the impact of electronic journals (e-journals on scholarly communication, by measuring the extent to which they are being cited in the literature, both print and electronic. The intent is to provide a snapshot of the impact e-journals were having on scholarly communication at a given point in time, roughly the end of 1995. This study provides one measure of that impact, specifically on the formal, as opposed to informal, communication process. The study also examines the forms in which scholars cite e-journals, the accuracy and completeness of citations to e-journals, and practical difficulties faced by scholars and researchers who wish to retrieve e-journals through the networks.

    This paper proposes a Minimum Span Tree (MST) based image segmentation method for UAV images in coastal area. An edge weight based optimal criterion (merging predicate) is defined, which based on statistical learning theory (SLT). And we used a scale control parameter to control the segmentation scale. Experiments based on the high resolution UAV images in coastal area show that the proposed merging predicate can keep the integrity of the objects and prevent results from over segmentation. The segmentation results proves its efficiency in segmenting the rich texture images with good boundary of objects.

  8. Scholarly context not found: one in five articles suffers from reference rot.

    Directory of Open Access Journals (Sweden)

    Martin Klein

    Full Text Available The emergence of the web has fundamentally affected most aspects of information communication, including scholarly communication. The immediacy that characterizes publishing information to the web, as well as accessing it, allows for a dramatic increase in the speed of dissemination of scholarly knowledge. But, the transition from a paper-based to a web-based scholarly communication system also poses challenges. In this paper, we focus on reference rot, the combination of link rot and content drift to which references to web resources included in Science, Technology, and Medicine (STM articles are subject. We investigate the extent to which reference rot impacts the ability to revisit the web context that surrounds STM articles some time after their publication. We do so on the basis of a vast collection of articles from three corpora that span publication years 1997 to 2012. For over one million references to web resources extracted from over 3.5 million articles, we determine whether the HTTP URI is still responsive on the live web and whether web archives contain an archived snapshot representative of the state the referenced resource had at the time it was referenced. We observe that the fraction of articles containing references to web resources is growing steadily over time. We find one out of five STM articles suffering from reference rot, meaning it is impossible to revisit the web context that surrounds them some time after their publication. When only considering STM articles that contain references to web resources, this fraction increases to seven out of ten. We suggest that, in order to safeguard the long-term integrity of the web-based scholarly record, robust solutions to combat the reference rot problem are required. In conclusion, we provide a brief insight into the directions that are explored with this regard in the context of the Hiberlink project.

    Full Text Available In the editorial Introduction to Women, Science, and Technology: A Reader in Feminist Science Studies, published in 2001, can be found the exemplary statement that among the norms for acquiring scientific knowledge is “skepticism (all claims should be scrutinized for errors”. In this article, I address a section relating to historical contentions in the same volume that, I argue, fails to live up to this basic standard of scholarly research. It is now quite widely believed that Mileva Marić, Einstein’s first wife, played an active role in Einstein’s early scientific work until well after they married in 1903. Some commentators go so far as to argue that she coauthored his three major 1905 papers, while others contend that she solved the mathematical problems for him. I examine the claims made in relation to Marić in the section in question in the above-cited volume, and investigate the sources of the evidential claims that have been adduced to support them. I conclude that the several claims are without reliable evidential bases.

    2014-01-01

    The number of scholarly documents available on the web is estimated using capture/recapture methods by studying the coverage of two major academic search engines: Google Scholar and Microsoft Academic Search. Our estimates show that at least 114 million English-language scholarly documents are accessible on the web, of which Google Scholar has nearly 100 million. Of these, we estimate that at least 27 million (24%) are freely available since they do not require a subscription or payment of any kind. In addition, at a finer scale, we also estimate the number of scholarly documents on the web for fifteen fields: Agricultural Science, Arts and Humanities, Biology, Chemistry, Computer Science, Economics and Business, Engineering, Environmental Sciences, Geosciences, Material Science, Mathematics, Medicine, Physics, Social Sciences, and Multidisciplinary, as defined by Microsoft Academic Search. In addition, we show that among these fields the percentage of documents defined as freely available varies significantly, i.e., from 12 to 50%. PMID:24817403

    Full Text Available The number of scholarly documents available on the web is estimated using capture/recapture methods by studying the coverage of two major academic search engines: Google Scholar and Microsoft Academic Search. Our estimates show that at least 114 million English-language scholarly documents are accessible on the web, of which Google Scholar has nearly 100 million. Of these, we estimate that at least 27 million (24% are freely available since they do not require a subscription or payment of any kind. In addition, at a finer scale, we also estimate the number of scholarly documents on the web for fifteen fields: Agricultural Science, Arts and Humanities, Biology, Chemistry, Computer Science, Economics and Business, Engineering, Environmental Sciences, Geosciences, Material Science, Mathematics, Medicine, Physics, Social Sciences, and Multidisciplinary, as defined by Microsoft Academic Search. In addition, we show that among these fields the percentage of documents defined as freely available varies significantly, i.e., from 12 to 50%.

    Changes to the chromatin structure accompany aging, but the molecular mechanisms underlying aging and the accompanying changes to the chromatin are unclear. Here, we report a mechanism whereby altering chromatin structure regulates life span. We show that normal aging is accompanied by a profound loss of histone proteins from the genome. Indeed, yeast lacking the histone chaperone Asf1 or acetylation of histone H3 on lysine 56 are short lived, and this appears to be at least partly due to their having decreased histone levels. Conversely, increasing the histone supply by inactivation of the histone information regulator (Hir) complex or overexpression of histones dramatically extends life span via a pathway that is distinct from previously known pathways of life span extension. This study indicates that maintenance of the fundamental chromatin structure is critical for slowing down the aging process and reveals that increasing the histone supply extends life span.

    2015-06-01

    Full Text Available Background: Research training is essential to the development of well-rounded physicians. Although many pediatric residency programs require residents to complete a research project, it is often challenging to integrate research training into educational programs. Objective: We aimed to develop an innovative research program for pediatric residents, called the Scholarly Activity Guidance and Evaluation (SAGE program. Methods: We developed a competency-based program which establishes benchmarks for pediatric residents, while providing ongoing academic mentorship. Results: Feedback from residents and their research supervisors about the SAGE program has been positive. Preliminary evaluation data have shown that all final-year residents have met or exceeded program expectations. Conclusions: By providing residents with this supportive environment, we hope to influence their academic career paths, increase their research productivity, promote evidence-based practice, and ultimately, positively impact health outcomes.

    2011-03-01

    What is our point of no return? Caesar proclaimed 'the die is cast' while crossing the Rubicon, but rarely does modern society find so visible a threshold in our continued degradation of ecosystems and the services they provide. Humans have always used their surroundings to make a living— sometimes successfully, sometimes not (Diamond 2005)—and we intuitively know that there are boundaries to our exploitation. But defining these boundaries has been a challenge since Malthus first prophesied that nature would limit the human population (Malthus 1798). In 2009, Rockström and colleagues tried to quantify what the 6.8 billion (and counting) of us could continue to get away with, and what we couldn't (Rockström et al 2009). In selecting ten 'planetary boundaries', the authors contend that a sustainable human enterprise requires treating a number of environmental thresholds as points of no return. They suggest we breach these Rubicons at our own peril, and that we've already crossed three: biodiversity loss, atmospheric CO2, and disruption of the global nitrogen (N) cycle. As they clearly hoped, the very act of setting targets has provoked scientific inquiry about their accuracy, and about the value of hard targets in the first place (Schlesinger 2009). Such debate is a good thing. Despite recent emphasis on the science of human-ecosystem interactions, understanding of our planetary boundaries is still in its infancy, and controversy can speed scientific progress (Engelhardt and Caplan 1987). A few weeks ago in this journal, Carpenter and Bennett (2011) took aim at one of the more controversial boundaries in the Rockström analysis: that for human alteration of the global phosphorus (P) cycle. Rockström's group chose riverine P export as the key indicator, suggesting that humans should not exceed a value that could trigger widespread marine anoxic events—and asserting that we have not yet crossed this threshold. There are defensible reasons for a marine

  6. Albedo Boundary

    MGS MOC Release No. MOC2-510, 11 October 2003The sharp, nearly straight line that runs diagonally across the center of this April 2003 Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image is an albedo boundary. Albedois a term that refers to reflectance of sunlight. A surface with a low albedo is one that appears dark because it reflects less light than a high albedo (bright) surface. On Mars, albedo boundaries occur between two materials of differing texture, particle size, or composition, or some combination of these three factors. The boundary shown here is remarkable because it is so sharp and straight. This is caused by wind. Most likely, the entire surface was once covered with the lower-albedo (darker) material that is now seen in the upper half of the image. At some later time, wind stripped away this darker material from the surfaces in the lower half of the image. The difference in albedo here might be related to composition, and possibly particle size. This picture is located near the southwest rim of Schiaparelli Basin at 5.5oS, 345.9oW. The picture covers an area 3 km (1.9 mi) wide and is illuminated by sunlight from the left.

    2010-01-01

    The Fulbright program was established by the US Congress to "enable the government of the United States to increase mutual understanding between the people of the United States and the people of other countries." The Core Fulbright Scholar Program sends more than 800 US faculty and administrators to 125 countries to lecture or conduct research around the world each year. Unfortunately, only 28 faculty members from the US veterinary colleges have used Fulbright Scholar opportunities in the last 20 years (1989-2009). Considering recent worldwide events, such as the global dispersion of the Asian strain of highly pathogenic avian influenza and pandemic H1N1 2009 affecting human and animal species, the importance of awareness and education of veterinarians to such global issues is obviously urgent. Therefore, Fulbright scholarships represent an important opportunity to gain experience and bring this time-critical information back to fellow faculty and students. Veterinarians who wish to contribute to internationalization of the curricula and their campuses should consider applying for Fulbright Scholar support to launch their career in this pivotal direction.

  13. Mentoring K scholars: strategies to support research mentors.

    Science.gov (United States)

    Burnham, Ellen L; Schiro, Stephanie; Fleming, Michael

    2011-06-01

    The goal of this paper is to present strategies utilized to support K scholar research mentors. K scholars are generally assistant professors who are close to developing independent research programs. Of all the various types of mentees, K scholars offer the greatest challenges, as well as the greatest rewards, for research mentors. To see one's mentee achieve independent PI status and become an established investigator is one of the great joys of being a research mentor. Research mentors for K scholars, however, may not directly benefit from their mentoring relationship, neither in terms of obtaining data to support their research program or laboratory, nor in assistance with grants or scientific papers. There is a pressing need for the research community to address the workload, institutional expectations, and reward system for research mentors. The dearth of research mentors and role models in clinical translational science parallels the decreasing number of physicians choosing careers in clinical research. While there is limited empirical information on the effectiveness of mentor support mechanisms, this white paper concludes that providing mentor support is critical to expanding the available pool of mentors, as well as providing training opportunities for K scholars.

  14. The mechanical response of multi-tower continuous-span suspension bridge deck pavement based on whole bridge analysis

    Institute of Scientific and Technical Information of China (English)

    Li Hongtao; Zhang Chenchen; Hu Jing; Qian Zhendong

    2011-01-01

    The effect of multiple span suspension structure on the mechanical response of bridge deck pavement was studied, and finite element analysis (FEM) of stress and strain of pavement according to the bridge floor system features of super-long and high flexibility was made. Meanwhile, the FEM results were compared with those of the single span suspension structure. Three-stage analytic hierarchy process (AHP) is developed to analyze the mechanical response including whole bridge analysis, partial beams section analysis and orthotropic plate analysis. The most unfavorable load position was determined by the numerical solutions acquired from each stage to study the main mechanical index of multiple span suspension structure. The FEM results showed that the mechanical response numerical solutions by using the three-stage AHP are greater than those by simplified boundary condition, and the force condition of multiple span suspension structure is worse than that of the single span suspension structure.

  15. A scholarly intermediary between the Ottoman Empire and Renaissance Europe.

    Science.gov (United States)

    Morrison, Robert

    2014-03-01

    This essay studies Moses Galeano, a Jewish scholar with ties to Crete and the Ottoman Sultan's court, who traveled to the Veneto around 1500. After describing Galeano's intellectual milieu, it focuses, first, on circumstantial evidence that he transmitted information central to the rise of Renaissance astronomy. Galeano knew of theories that strongly resemble portions of astronomy texts written by Giovanni Battista Amico and Girolamo Fracastoro at Padua a few decades later. He also knew about theories pioneered by the Damascene Ibn al-Shāţir (d. 1375) that strongly resemble portions of Copernicus's work. Next, the article turns to concrete evidence showing that Galeano was part of a network of Jewish scholars who did have contact with Christian scholars in Europe. The essay concludes that, while it is impossible to prove that Galeano had direct contact with Copernicus, he most likely had contact with some European astronomer(s) in the Veneto.

This overall model differs from those previously studied in the literature in that the elastic chamber floor is here more realistically modeled by a hyperbolic Kirchoff equation, rather than by a parabolic Euler-Bernoulli equation with Kelvin-Voight structural damping, as in past literature. Thus, the hyperbolic/parabolic coupled system of past literature is replaced here by a hyperbolic/hyperbolic coupled model. The main result of this paper is a uniform stabilization of the coupled PDE system by a (physically appealing boundary dissipation.

    2016-01-01

    Dietary restriction (DR) without malnutrition is associated with longevity in various organisms. However, it has also been shown that reduced calorie intake is often ineffective in extending life span. Selecting optimal dietary regimens for DR studies is complicated, as the same regimen may lead to different outcomes depending on genotype and environmental factors. Recent studies suggested that interventions such as moderate protein restriction with or without adequate nutrition (e.g., particular amino acids or carbohydrates) may have additional beneficial effects mediated by certain metabolic and hormonal factors implicated in the biology of aging, regardless of total calorie intake. In particular, it was shown that restriction of a single amino acid, methionine, can mimic the effects of DR and extend life span in various model organisms. We discuss the beneficial effects of a methionine-restricted diet, the molecular pathways involved, and the use of this regimen in longevity interventions.

  20. Octave Spanning Frequency Comb on a Chip

    CERN Document Server

    Del'Haye, P; Gavartin, E; Holzwarth, R; Kippenberg, T J

    2009-01-01

    Optical frequency combs have revolutionized the field of frequency metrology within the last decade and have become enabling tools for atomic clocks, gas sensing and astrophysical spectrometer calibration. The rapidly increasing number of applications has heightened interest in more compact comb generators. Optical microresonator based comb generators bear promise in this regard. Critical to their future use as 'frequency markers', is however the absolute frequency stabilization of the optical comb spectrum. A powerful technique for this stabilization is self-referencing, which requires a spectrum that spans a full octave, i.e. a factor of two in frequency. In the case of mode locked lasers, overcoming the limited bandwidth has become possible only with the advent of photonic crystal fibres for supercontinuum generation. Here, we report for the first time the generation of an octave-spanning frequency comb directly from a toroidal microresonator on a silicon chip. The comb spectrum covers the wavelength range...

    Full Text Available We present the numbers of spanning forests on the Sierpinski gasket $SG_d(n$ at stage $n$ with dimension $d$ equal to two, three and four, and determine the asymptotic behaviors. The corresponding results on the generalized Sierpinski gasket $SG_{d,b}(n$ with $d=2$ and $b=3,4$ are obtained. We also derive the upper bounds of the asymptotic growth constants for both $SG_d$ and $SG_{2,b}$.

    2011-01-01

    Full Text Available A study of the natural frequencies and mode shapes of a multi-span beam is carried out by introducing constrained beam characteristic functions. The conventional method used for the dynamic analysis of such a beam is to consider span-wise characteristic function solution and then to solve it by using compatibility conditions such as the continuity in the a slope and bending moment at the intermediate supports and boundary conditions at the ends. In the method proposed here, the matrix size is reduced and, if the support conditions are symmetric about the midpoint, the symmetry and anti-symmetry conditions at the midpoint can be conveniently exploited for computational economy. The natural frequencies occur in clusters, each one containing the number of natural frequencies equal to the number of spans. The results are presented and discussed.

  4. Vision in Flies: Measuring the Attention Span.

    Koenig, Sebastian; Wolf, Reinhard; Heisenberg, Martin

    2016-01-01

    A visual stimulus at a particular location of the visual field may elicit a behavior while at the same time equally salient stimuli in other parts do not. This property of visual systems is known as selective visual attention (SVA). The animal is said to have a focus of attention (FoA) which it has shifted to a particular location. Visual attention normally involves an attention span at the location to which the FoA has been shifted. Here the attention span is measured in Drosophila. The fly is tethered and hence has its eyes fixed in space. It can shift its FoA internally. This shift is revealed using two simultaneous test stimuli with characteristic responses at their particular locations. In tethered flight a wild type fly keeps its FoA at a certain location for up to 4s. Flies with a mutation in the radish gene, that has been suggested to be involved in attention-like mechanisms, display a reduced attention span of only 1s.

    Dias, João

    2013-12-01

    The sovereign debt crisis in the euro area has not yet been solved and recent developments in Spain and Italy have further deteriorated the situation. In this paper we develop a new approach to analyze the ongoing Eurozone crisis. Firstly, we use Maximum Spanning Trees to analyze the topological properties of government bond rates’ dynamics. Secondly, we combine the information given by both Maximum and Minimum Spanning Trees to obtain a measure of market dissimilarity or disintegration. Thirdly, we extend this measure to include a convenient distance not limited to the interval [0, 2]. Our empirical results show that Maximum Spanning Tree gives an adequate description of the separation of the euro area into two distinct groups: those countries strongly affected by the crisis and those that have remained resilient during this period. The measures of market dissimilarity also reveal a persistent separation of these two groups and, according to our second measure, this separation strongly increased during the period July 2009-March 2012.

  7. Impounding Experimental Research of Large Span Aqueduct

    Full Text Available In this study, we have a research of the impounding experimental research of large span aqueduct. Caohe aqueduct is the mark building of the middle line of the South-to-North Water Diversion Project, of which the span is 30m. For this aqueduct, the structure is relatively complicated with great technical difficulties, what’s more there's no engineering experience or theoretical method to provide reference in domestic and abroad. It can be seen clear that whether the actual stressing state, deformation conditions and prestressed tension effect etc. meet the design requirements will directly affect the safe operation of aqueduct, so the impounding experiment of the aqueduct was carried out before formal operation. At the meanwhile, the deformation characteristics and stress characteristics of the aqueduct under various impounding conditions were analyzed in detail. The experiment results analysis shows that, the aqueduct structure is under a good elastic working condition with only 0.98mm maximum deflection deformation at mid-span, which meets the design and specification requirements. At the same time, all of the measure point’s stress is in the range of designed material, which means the structure form is safe and reliable and can meet the requirements of the later operation good.

    2015-05-01

    Full Text Available This article aims to point out emerging roles and responsibilities for academic librarians with the potential of better integrating the library in the research process. In order to find out how to enhance the online reputation and discoverability of individual faculty members as well as their affiliated institutions, the authors worked side-by-side with researchers in the United States and Europe to explore, create, revise, and disambiguate scholarly profiles in various software applications. In an attempt to understand and organize scholarly social media, including new, alternative metrics, the authors reviewed and classified the major academic profile platforms, highlighting the overlapping elements, benefits, and drawbacks inherent in each. The consensus is that it would be time-consuming to keep one’s profile current and accurate on all of these platforms, given the plethora of underlying problems, also discussed in detail in the article. However, it came as a startling discovery that reluctance to engage with scholarly social media may cause a misrepresentation of a researcher’s academic achievements and may come with unforeseen consequences. The authors claim that current skills and competencies can secure an essential role for academic librarians in the research workflow by means of monitoring and navigating researcher profiles in scholarly social media in order to best represent the scholarship of their host institutions.

  3. Building the scholarly society infrastructure in physics in interwar America

    Science.gov (United States)

    Scheiding, Tom

    2013-11-01

    Starting in the interwar years both the quantity and quality of physics research conducted within the United States increased dramatically. To accommodate these increases there needed to be significant changes to the infrastructure within the scholarly society and particularly to the organization's ability to publish and distribute scholarly journals. Significant changes to the infrastructure in physics in the United States began with the formation of the American Institute of Physics as an umbrella organization for the major scholarly societies in American physics in 1931. The American Institute of Physics played a critical role in bringing about an expansion in the size of and breadth of coverage within scholarly journals in physics. The priority the American Institute of Physics placed on establishing a strong publication program and the creation of the American Institute of Physics itself were stimulated by extensive involvement and financial investments from the Chemical Foundation. It was journals of sufficient size and providing an appropriate level of coverage that were essential after World War II as physicists made use of increased patronage and public support to conduct even more research. The account offered here suggests that in important respects the significant government patronage that resulted from World War II accelerated changes that were already underway.

  7. Structure-borne low-frequency noise from multi-span bridges: A prediction method and spatial distribution

    Science.gov (United States)

    Song, X. D.; Wu, D. J.; Li, Q.; Botteldooren, D.

    2016-04-01

    Structure-borne noise from railway bridges at far-field points is an important indicator in environmental noise assessment. However, studies that predict structure-borne noise tend to model only single-span bridges, thus ignoring the sound pressure radiating from adjacent spans. To simulate the noise radiating from multi-span bridges induced by moving vehicles, the vibrations of a multi-span bridge are first obtained from a three-dimensional (3D) vehicle-track-bridge dynamic interaction simulation using the mode superposition method. A procedure based on the 2.5-dimensional (2.5D) boundary element method (BEM) is then presented to promote the efficiency of acoustical computation compared with the 3D BEM. The simulated results obtained from both the single-span and multi-span bridge models are compared with the measured results. The sound predictions calculated from the single-span model are accurate only for a minority of near-field points. In contrast, the sound pressures calculated from the multi-span bridge model match the measured results in both the time and frequency domains for all of the near-field and far-field points. The number of bridge spans required in the noise simulation is then recommended related to the distance between the track center and the field points of interest. The spatial distribution of multi-span structure-borne noise is also studied. The variation in sound pressure levels is insignificant along the length of the bridge, which validates the finding that the sound test section can be selected at an arbitrary plane perpendicular to the multi-span bridge.

  13. Matroidal Degree-Bounded Minimum Spanning Trees

    CERN Document Server

    Zenklusen, Rico

    2011-01-01

    We consider the minimum spanning tree (MST) problem under the restriction that for every vertex v, the edges of the tree that are adjacent to v satisfy a given family of constraints. A famous example thereof is the classical degree-constrained MST problem, where for every vertex v, a simple upper bound on the degree is imposed. Iterative rounding/relaxation algorithms became the tool of choice for degree-bounded network design problems. A cornerstone for this development was the work of Singh and Lau, who showed for the degree-bounded MST problem how to find a spanning tree violating each degree bound by at most one unit and with cost at most the cost of an optimal solution that respects the degree bounds. However, current iterative rounding approaches face several limits when dealing with more general degree constraints. In particular, when several constraints are imposed on the edges adjacent to a vertex v, as for example when a partition of the edges adjacent to v is given and only a fixed number of elemen...

  16. THE IMPLEMENTATION OF FINDINGS PUBLISHED IN SCHOLARLY ARTICLES

    Directory of Open Access Journals (Sweden)

    Martin A. Hubbe

    2010-07-01

    Full Text Available Articles published in scholarly journals, such as this one, tend to be mainly addressed to researchers at universities. Industrial follow-up and implementation of results from a scholarly article appears to be the exception, rather than the rule. Research grant specifications, as well as university policies, favor the generation of new knowledge, rather than the implementation of good ideas. But without patent protection, corporations have low motivation to expend the considerable effort to reduce ideas to practice after they have been openly published. The author speculates that the situation could be much more dynamic if there were a system of priority of implementation. According to such a system, the first company to successfully implement an idea that first appears in a peer-reviewed journal article, as validated by its debut in the marketplace, would have a grace period during which competitors would have to pay them a fee to sell a generic version of the same thing.

    Full Text Available Astronomy is similar to other scientific disciplines in that scholarly publication relies on the presentation and interpretation of data. But although astronomy now has archives for its primary research telescopes and associated surveys, the highly processed data that is presented in the peer-reviewed journals and is the basis for final analysis and interpretation is generally not archived and has no permanent repository. We have initiated a project whose goal is to implement an end-to-end prototype system which, through a partnership of a professional society, that society’s scholarly publications/publishers, research libraries, and an information technology substrate provided by the Virtual Observatory, will capture high-level digital data as part of the publication process and establish a distributed network of curated, permanent data repositories. The data in this network will be accessible through the research journals, astronomy data centers, and Virtual Observatory data discovery portals.

The scholars are the people who have command and expertise in any of the curriculum components. The article focuses on the role of curriculum scholars in Pakistan and how and what type of changes they can initiate to bring harmony and tolerance, character and quality in development of curricula. The international issues, trends evolving globalization can be enhanced and incorporated to foster individual and social development. It is a qualitative study based on historical evidences and current researches highlighting the importance and role of curriculum scholars and meeting the world class education system. The issues and trends mentioned by developed countries curriculum experts paved way to synthesis them with local rising issues and trends.The study concluded that the curriculum developers have dynamic roles in curriculum debates because they have to work for bridging gaps of developing and developed nation, addressing local curriculum issues, Using pragmatic approach rather than ideological, reorganizing of recent curricula, solving language issue, facing controversies on curriculum change, making it unified and centralized, diverting curricula to research orientation, obtaining continuous feedback and developing harmony in society at the same time. It is imperative for scholars to have effective communication skills and dynamic personality to incorporate the future trends without creating conflicts and confusion in the society. They need to know the skill to motivate and mould high ups for future changes and bring changes without development of controversies.

  5. Understanding the Development of Scholarly Metrics in a Networked Society

    Directory of Open Access Journals (Sweden)

    Anup Kumar Das

    2016-06-01

    Full Text Available This book is a collection of 55 citation classics published between 1955 and 2013 written by the well-known scholars in bibliometrics, scientometrics, science policy, research evaluation, and research communications. The editors of this volume, Blaise Cronin and Cassidy R Sugimoto took a great effort to prepare this collection. Then they curated the contents in six parts, namely, (I Concepts and Theories, (II Validity issues, (III Data Sources, (IV Indicators, (V Science Policy, and (VI Systematic Effects, giving a lyrical title for each essay introducing a part. The editors here introduce each part equally eloquently while organizing the chapters. In addition to an insightful introductory text for each part, the editors offer an analytical introduction to the book and a future analysis in the epilogue. The editors of the book feel that the fast-expanding field of scholarly metrics requires a relook, particularly in light of the theoretical, conceptual, methodological and ethical dimensions. They further propose that“by assembling a representative cross-section of the literature critiquing evaluative bibliometrics we may be able to raise awareness of the approach’s limitations and also encourage greater procedural caution among relevant constituencies” (p. 4.Thus, the book gets unveiled to identify the authoritative papers in evaluative bibliometrics, and subsequently to enjoy the microscopic view for each milestone in the timeline of scholarly metrics.

  6. MESUR: USAGE-BASED METRICS OF SCHOLARLY IMPACT

    Energy Technology Data Exchange (ETDEWEB)

    BOLLEN, JOHAN [Los Alamos National Laboratory; RODRIGUEZ, MARKO A. [Los Alamos National Laboratory; VAN DE SOMPEL, HERBERT [Los Alamos National Laboratory

    2007-01-30

    The evaluation of scholarly communication items is now largely a matter of expert opinion or metrics derived from citation data. Both approaches can fail to take into account the myriad of factors that shape scholarly impact. Usage data has emerged as a promising complement to existing methods o fassessment but the formal groundwork to reliably and validly apply usage-based metrics of schlolarly impact is lacking. The Andrew W. Mellon Foundation funded MESUR project constitutes a systematic effort to define, validate and cross-validate a range of usage-based metrics of schlolarly impact by creating a semantic model of the scholarly communication process. The constructed model will serve as the basis of a creating a large-scale semantic network that seamlessly relates citation, bibliographic and usage data from a variety of sources. A subsequent program that uses the established semantic network as a reference data set will determine the characteristics and semantics of a variety of usage-based metrics of schlolarly impact. This paper outlines the architecture and methodology adopted by the MESUR project and its future direction.

  7. Supporting the scholar role in intensive care nursing.

    Melles, M; Freudenthal, A; de Ridder, H

    2012-01-01

    This study investigates how future informatics applications can support and challenge intensive care nurses (ICU nurses) to grow and learn continuously. To this end a research-and-design tool is introduced which is based on a model of the nursing process that starts from the idea that a nurse fulfills three different roles: the role of practitioner (using information immediately to base actions upon), the role of scholar (using information later on to learn from) and the role of human (coping with stress and dealing with emotions). In this paper the focus is on the scholar role. Twenty-eight intensive care staff members from six different hospitals were asked to recount an imposing experience from the perspective of each role. Regarding the scholar role, the participants mentioned 77 learning strategies they adopt for individual as well as organizational learning. Individual learning concerned reflection on former patient cases, reflection on current patient cases to anticipate a change in the patient's condition and reflection on personal behavior and decisions. Organizational learning concerned reflection on former patient cases. Examples of specific strategies were formal team evaluations focused on procedure and understanding the perspective of team members, being present at autopsies, and giving feedback on the nursing skills of colleagues. Based on these strategies design implications are defined for future nursing informatics applications, which will be presented. PMID:22317164

    This paper presents a study of an organisation, which is undergoing a process transforming organisational and technological boundaries. In particular, we shall look at three kinds of boundaries: the work to maintain and change the boundary between the organisation and its customers; boundaries.......After analysing the history and the current boundary work, the paper will propose new technological support for boundary work. In particular the paper will suggest means of supporting boundaries when these are productive and for changing boundaries when this seems more appropriate. In total, flexible technologies...... seem a core issue when dealing with technology for boundaries....

  9. Faster generation of random spanning trees

    CERN Document Server

    Kelner, Jonathan A

    2009-01-01

    In this paper, we set forth a new algorithm for generating approximately uniformly random spanning trees in undirected graphs. We show how to sample from a distribution that is within a multiplicative $(1+\\delta)$ of uniform in expected time $\\TO(m\\sqrt{n}\\log 1/\\delta)$. This improves the sparse graph case of the best previously known worst-case bound of $O(\\min \\{mn, n^{2.376}\\})$, which has stood for twenty years. To achieve this goal, we exploit the connection between random walks on graphs and electrical networks, and we use this to introduce a new approach to the problem that integrates discrete random walk-based techniques with continuous linear algebraic methods. We believe that our use of electrical networks and sparse linear system solvers in conjunction with random walks and combinatorial partitioning techniques is a useful paradigm that will find further applications in algorithmic graph theory.

    Macfarlane, B A; Flynn, C M L

    2015-01-01

    Chemical tagging of stellar debris from disrupted open clusters and associations underpins the science cases for next-generation multi-object spectroscopic surveys. As part of the Galactic Archaeology project TraCD (Tracking Cluster Debris), a preliminary attempt at reconstructing the birth clouds of now phase-mixed thin disk debris is undertaken using a parametric minimum spanning tree (MST) approach. Empirically-motivated chemical abundance pattern uncertainties (for a 10-dimensional chemistry-space) are applied to NBODY6-realised stellar associations dissolved into a background sea of field stars, all evolving in a Milky Way potential. We demonstrate that significant population reconstruction degeneracies appear when the abundance uncertainties approach 0.1 dex and the parameterised MST approach is employed; more sophisticated methodologies will be required to ameliorate these degeneracies.

  12. From Exotic to Mainstream: A 10-year Odyssey from Internet Speed to Boundary Spanning with Scrum

    Science.gov (United States)

    Baskerville, Richard; Pries-Heje, Jan; Madsen, Sabine

    Based on four empirical studies conducted over a 10-year time period from 1999 to 2008 we investigate how local software processes interact with global changes in the software development context. In 1999 companies were developing software at high speed in a desperate rush to be first-to-market. In 2001 a new high speed/quick results development process had become established practice. In 2003 changes in the market created the need for a more balanced view on speed and quality, and in 2008 companies were successfully combining agile and plan driven approaches to achieve the benefits of both. The studies reveal a twostage pattern in which dramatic changes in the market causes disruption of established practices, experimentation, and process adaptations followed by consolidation of lessons learnt into a new (and once again mature) software development process. Limitations, implications, and areas for future research are discussed.

    The Science Policy Exchange (SPE) is a consortium of leaders in ecosystem research united to facilitate science from innovation to impact. In our unique model, we catalyze actionable science on pressing environmental issues such as climate change, and undertake comprehensive stakeholder engagement, public communication, and policy outreach. Built on more than 10 years of experience creating programs at the interface of science and policy at Hubbard Brook, Harvard Forest, and other LTER sites, we apply science communication research to practice in various ways depending on the context and problem being addressed. In keeping with the research on co-production and the importance of establishing credibility, salience, and legitimacy, we engage stakeholders from the outset of each project. Stakeholders and scientists collaborate to define the scope of the project, frame questions relevant to society, and define communication products to meet their needs. To promote broader distribution and uptake, we combine message development, storytelling, and media training to craft and deliver relatable stories that tap into news values and human values. Three recent SPE successes include: (1) Wildlands and Woodlands: A regional forest conservation report released in 2010 that generated 137 media stories and influenced land conservation policy, (2) Changes to the Land: A suite of communication products developed in 2013 for a landscape scenarios project in Massachusetts that saturated the state's media markets and have been widely cited by policymakers, and (3) Co-benefits of Carbon Standards: A national air quality report released in 2014 that was cited in 76 media stories and helped reframe the national debate on carbon dioxide emissions standards in terms of their potential local health and environmental benefits. We will describe our successful applications of science communication research and discuss several critical disconnections between research and practice. These include, how much and what form of stakeholder engagement is most appropriate for a given project? How does the state of the science and the current policy context shape the pathways to impact and associated communication strategies? What can we learn from advocacy campaign to make our science communication sustained and more effective?

  20. Life span study report 9, part 3

    International Nuclear Information System (INIS)

    The incidence of malignant tumors in the RERF Life Span Study (LSS) sample in Nagasaki as revealed by the Nagasaki Tumor Registry (Registry) has been investigated for the period 1959-78. No exposure status bias in data collection has been revealed. Neither method of diagnosis, reporting hospitals, nor the frequency of doubtful cases differ by exposure dose. Thus, the effect of a bias, if one exists, must be small and should not affect the interpretation of the results obtained in the present analysis. The risk of radiogenic cancer definitely increases with radiation dose for leukemia, cancer of the breast, lung, stomach, and thyroid, and suggestively so for cancer of the colon and urinary tract and multiple myeloma. However, there is no increase as yet for cancer of the esophagus, liver, gall bladder, uterus, ovary, and salivary gland, or for malignant lymphoma. For fatal cancers, these results strengthen those of the recent analysis of mortality based on death certificates on the same LSS cohort. In general, the relative risks based on incidence (that is, on Registry data) are either the same or slightly higher than those based on mortality for the same years; however, the absolute risk estimates (excess cancer per million person-year per rad) are far higher.

  1. Methionine restriction beyond life-span extension.

    Science.gov (United States)

    Ables, Gene P; Hens, Julie R; Nichenametla, Sailendra N

    2016-01-01

    Dietary methionine restriction (MR) extends life span across species via various intracellular regulatory mechanisms. In rodents, MR induces resistance against adiposity, improves hepatic glucose metabolism, preserves cardiac function, and reduces body size, all of which can affect the onset of age-related diseases. Recent studies have shown that MR-affected biomarkers, such as fibroblast growth factor 21, adiponectin, leptin, cystathionine β synthase, and insulin-like growth factor 1, can potentially alter physiology. The beneficial effects of MR could be explained in part by its ability to reduce mitochondrial oxidative stress. Studies have revealed that MR can reduce reactive oxygen species that damage cells and promote cancer progression. It has been demonstrated that either MR or the targeting of specific genes in the methionine cycle could induce cell apoptosis while decreasing proliferation in several cancer models. The complete mechanism underlying the actions of MR on the cell cycle during cancer has not been fully elucidated. Epigenetic mechanisms, such as methylation and noncoding RNAs, are also possible downstream effectors of MR; future studies should help to elucidate some of these mechanisms. Despite evidence that changes in dietary methionine can affect epigenetics, it remains unknown whether epigenetics is a mechanism in MR. This review summarizes research on MR and its involvement in metabolism, cancer, and epigenetics.

  2. Data resources for life span study

    International Nuclear Information System (INIS)

    The Life Span Study sample consists originally of 82,000 A-bomb survivors who were enumerated from a nation-wide A-bomb survivors survey conducted in 1950 and 27,000 non-exposed individuals. Mortality ascertainment is essentially complete by periodic checks against Koseki, but its weakness is the inexactness of the cause of death stated on the death certificate. Some of the latter can be compensated for by collateral use of autopsy information and the data from Tissue and Tumor Registries. Updating of the Hiroshima Tumor Registry has been recently completed and no serious bias related to radiation dose was observed in the data collection for either Hiroshima or Nagasaki. Also the completeness of registration is the highest among registries in Japan. The Tumor and Tissue Registries should be very useful data resources to determine the radiation effects on non-fatal cancers i.e., thyroid and breast cancers as well as the fatal types. Lack of information on the out-migrated subjects from the two cities should be seriously considered, especially those who were of young age at the time of the bombing. Information on environmental factors other than radiation exposure, such as occupation, smoking and diet, has been collected by interviewers, mail questionnaires or record linkage with census data, since 1960. Such information is also currently obtained on a case-control basis for certain sites of cancer, such as breast, lung, colon and rectum, in this cohort. 11 references, 6 tables

  7. Genetic determinants of human health span and life span: progress and new opportunities.

    Directory of Open Access Journals (Sweden)

    George M Martin

    2007-07-01

    Full Text Available We review three approaches to the genetic analysis of the biology and pathobiology of human aging. The first and so far the best-developed is the search for the biochemical genetic basis of varying susceptibilities to major geriatric disorders. These include a range of progeroid syndromes. Collectively, they tell us much about the genetics of health span. Given that the major risk factor for virtually all geriatric disorders is biological aging, they may also serve as markers for the study of intrinsic biological aging. The second approach seeks to identify allelic contributions to exceptionally long life spans. While linkage to a locus on Chromosome 4 has not been confirmed, association studies have revealed a number of significant polymorphisms that impact upon late-life diseases and life span. The third approach remains theoretical. It would require longitudinal studies of large numbers of middle-aged sib-pairs who are extremely discordant or concordant for their rates of decline in various physiological functions. We can conclude that there are great opportunities for research on the genetics of human aging, particularly given the huge fund of information on human biology and pathobiology, and the rapidly developing knowledge of the human genome.

    2016-01-01

    Many new websites and online tools have come into existence to support scholarly communication in all phases of the research workflow. To what extent researchers are using these and more traditional tools has been largely unknown. This 2015-2016 survey aimed to fill that gap. Its results may help decision making by stakeholders supporting researchers and may also help researchers wishing to reflect on their own online workflows. In addition, information on tools usage can inform studies of changing research workflows. The online survey employed an open, non-probability sample. A largely self-selected group of 20663 researchers, librarians, editors, publishers and other groups involved in research took the survey, which was available in seven languages. The survey was open from May 10, 2015 to February 10, 2016. It captured information on tool usage for 17 research activities, stance towards open access and open science, and expectations of the most important development in scholarly communication. Respondents' demographics included research roles, country of affiliation, research discipline and year of first publication. PMID:27429740

    The research blog has become a popular mechanism for the quick discussion of scholarly information. However, unlike peer-reviewed journals, the characteristics of this form of scientific discourse are not well understood, for example in terms of the spread of blogger levels of education, gender and institutional affiliations. In this paper we fill this gap by analyzing a sample of blog posts discussing science via an aggregator called ResearchBlogging.org (RB). ResearchBlogging.org aggregates posts based on peer-reviewed research and allows bloggers to cite their sources in a scholarly manner. We studied the bloggers, blog posts and referenced journals of bloggers who posted at least 20 items. We found that RB bloggers show a preference for papers from high-impact journals and blog mostly about research in the life and behavioral sciences. The most frequently referenced journal sources in the sample were: Science, Nature, PNAS and PLoS One. Most of the bloggers in our sample had active Twitter accounts connected with their blogs, and at least 90% of these accounts connect to at least one other RB-related Twitter account. The average RB blogger in our sample is male, either a graduate student or has been awarded a PhD and blogs under his own name.

    Tumminello, M; Lillo, F; Micciché, S; Mantegna, R N

    2006-01-01

    We introduce a new technique to associate a spanning tree to the average linkage cluster analysis. We term this tree as the Average Linkage Minimum Spanning Tree. We also introduce a technique to associate a value of reliability to links of correlation based graphs by using bootstrap replicas of data. Both techniques are applied to the portfolio of the 300 most capitalized stocks traded at New York Stock Exchange during the time period 2001-2003. We show that the Average Linkage Minimum Spanning Tree recognizes economic sectors and sub-sectors as communities in the network slightly better than the Minimum Spanning Tree does. We also show that the average reliability of links in the Minimum Spanning Tree is slightly greater than the average reliability of links in the Average Linkage Minimum Spanning Tree.

  16. Identifying sexual differentiation genes that affect Drosophila life span

    Directory of Open Access Journals (Sweden)

    Tower John

    2009-12-01

    Full Text Available Abstract Background Sexual differentiation often has significant effects on life span and aging phenotypes. For example, males and females of several species have different life spans, and genetic and environmental manipulations that affect life span often have different magnitude of effect in males versus females. Moreover, the presence of a differentiated germ-line has been shown to affect life span in several species, including Drosophila and C. elegans. Methods Experiments were conducted to determine how alterations in sexual differentiation gene activity might affect the life span of Drosophila melanogaster. Drosophila females heterozygous for the tudor[1] mutation produce normal offspring, while their homozygous sisters produce offspring that lack a germ line. To identify additional sexual differentiation genes that might affect life span, the conditional transgenic system Geneswitch was employed, whereby feeding adult flies or developing larvae the drug RU486 causes the over-expression of selected UAS-transgenes. Results In this study germ-line ablation caused by the maternal tudor[1] mutation was examined in a long-lived genetic background, and was found to increase life span in males but not in females, consistent with previous reports. Fitting the data to a Gompertz-Makeham model indicated that the maternal tudor[1] mutation increases the life span of male progeny by decreasing age-independent mortality. The Geneswitch system was used to screen through several UAS-type and EP-type P element mutations in genes that regulate sexual differentiation, to determine if additional sex-specific effects on life span would be obtained. Conditional over-expression of transformer female isoform (traF during development produced male adults with inhibited sexual differentiation, however this caused no significant change in life span. Over-expression of doublesex female isoform (dsxF during development was lethal to males, and produced a limited

    Full Text Available The last two decades have been a time of significant development for the academic business ethics community. While a number of scholars have contributed to advances in the field, the work of the individuals who have contributed to its progress and growth through their business ethics research is still not comprehensively understood within the academic business ethics community. This study identifies those individuals who have made major contributions to the business ethics field by ranking authors who have published business ethics-related research in the following six journals over the past 20 years: the Journal of Business Ethics, the Academy of Management Review, the Academy of Management Journal, the Business Ethics Quarterly, the Administrative Science Quarterly; and Business & Society. The results of the study should be of interest to a number of constituencies as they provide the academic business ethics community with a better understanding of the history and evolution of the field and its development towards academic maturity.

    Full Text Available Reports results of a 1994-1995 questionnaire survey of faculty members in two Israeli universities, to discover whether changes in scholarly communication have occurred in the wake of technological changes that have added new media and tools and altered the structure and composition of library collections 477 questionnaires were returned out of 2361. Research focused on three components of the information gathering process: the researchers needs and approaches, channels of access to information, and information sources. Five basic approaches to information and eight information channels were defined. Concludes that, despite extensive changes in higher education, institutions and libraries that have occurred during the previous 45 years since the interest in information gathering behaviour began, patterns for obtaining information remain conservative and have resisted transformation. Professional periodicals are still the most important tools for obtaining professional information and monographs still play a major role.

    2010-01-01

    Citation analysis does not generally take the quality of citations into account: all citations are weighted equally irrespective of source. However, a scholar may be highly cited but not highly regarded: popularity and prestige are not identical measures of esteem. In this study we define popularity as the number of times an author is cited and prestige as the number of times an author is cited by highly cited papers. Information Retrieval (IR) is the test field. We compare the 40 leading researchers in terms of their popularity and prestige over time. Some authors are ranked high on prestige but not on popularity, while others are ranked high on popularity but not on prestige. We also relate measures of popularity and prestige to date of Ph.D. award, number of key publications, organizational affiliation, receipt of prizes/honors, and gender.

    Zhou, Jian; Chen, Lu; Wang, Ke; Yang, Fan

    2016-04-01

    In this paper, the minimum spanning tree problem is investigated on the graph with fuzzy edge weights. The notion of fuzzy ? -minimum spanning tree is presented based on the credibility measure, and then the solutions of the fuzzy ? -minimum spanning tree problem are discussed under different assumptions. First, we respectively, assume that all the edge weights are triangular fuzzy numbers and trapezoidal fuzzy numbers and prove that the fuzzy ? -minimum spanning tree problem can be transformed to a classical problem on a crisp graph in these two cases, which can be solved by classical algorithms such as the Kruskal algorithm and the Prim algorithm in polynomial time. Subsequently, as for the case that the edge weights are general fuzzy numbers, a fuzzy simulation-based genetic algorithm using Prüfer number representation is designed for solving the fuzzy ? -minimum spanning tree problem. Some numerical examples are also provided for illustrating the effectiveness of the proposed solutions.

  11. A Coons Patch Spanning a Finite Number of Curves Tested for Variationally Minimizing Its Area

    Directory of Open Access Journals (Sweden)

    Daud Ahmad

    2013-01-01

    Full Text Available In surface modeling a surface frequently encountered is a Coons patch that is defined only for a boundary composed of four analytical curves. In this paper we extend the range of applicability of a Coons patch by telling how to write it for a boundary composed of an arbitrary number of boundary curves. We partition the curves in a clear and natural way into four groups and then join all the curves in each group into one analytic curve by using representations of the unit step function including one that is fully analytic. Having a well-parameterized surface, we do some calculations on it that are motivated by differential geometry but give a better optimized and possibly more smooth surface. For this, we use an ansatz consisting of the original surface plus a variational parameter multiplying the numerator part of its mean curvature function and minimize with the respect to it the rms mean curvature and decrease the area of the surface we generate. We do a complete numerical implementation for a boundary composed of five straight lines, that can model a string breaking, and get about 0.82 percent decrease of the area. Given the demonstrated ability of our optimization algorithm to reduce area by as much as 23 percent for a spanning surface not close of being a minimal surface, this much smaller fractional decrease suggests that the Coons patch we have been able to write is already close of being a minimal surface.

    2013-11-01

    A synthetic jet is a zero-net-mass-flux flow control actuator that produces alternating ejection and suction of fluid momentum across an orifice. It has been used in numerous applications as an active flow control device to improve aerodynamic performance. Though their aerodynamic performance effects are well known, this present study seeks to understand the fluid dynamic effects of synthetic jets. Specifically, the work investigates the interactions of a finite span synthetic jet with a zero-pressure-gradient laminar boundary layer. This study was performed in a small-scale subsonic wind tunnel with an adjustable test section upper wall that was used to generate a zero-pressure-gradient boundary layer. Several finite span rectangular orifices were chosen for this study. Time and phase-averaged Stereoscopic Particle Image Velocimetry (SPIV) measurements were acquired at multiple planes upstream and downstream of the synthetic jet orifice to explore the interaction of the synthetic jet with the cross flow. The effects of the orifice aspect ratio (12, 18, and 24) and blowing ratio (0.5, 1, and 1.5) were investigated. The unsteady vortical structures observed in the near field and the steady structures in the far field are discussed.

    The subsea gas production system of Mexilhao Field SPS-35, Santos Basin, offshore Brazil, is composed basically of two rigid 12.75 inches production flow lines approximately 21 km long installed in a fairly rough seabed. During the basic design, the free span assessment was performed considering the maximum allowable free span length determined by the response model proposed by DNV-RP-F105. This approach resulted in a large number of predicted free span requiring corrections, leading to a higher capital cost for the project. In this sense, a detailed free span VIV fatigue assessment was proposed, considering multi-spans and multi-mode effects and also the post lay survey data. The assessment followed the DNV-RP-F105 recommendations for multi-spans and multi-mode effects, using Finite Element Analysis to determine the natural frequencies, mode shapes and corresponding stresses associated with the mode shapes. The assessment was performed in three stages, the first during the detailed design as part of the bottom roughness analysis using the expected residual pipelay tension. The second stage was performed after pipelay, considering the post-lay survey data, where the actual requirements for span correction were determined. Actual pipelay tension was used and seabed soil stiffness adjusted in the model to match the as-laid pipeline profile obtained from the survey data. The first and second stage assessments are seamlessly automated to speed up the evaluation process and allow for quick response in the field, which was important to keep the construction vessel time minimized. The third stage was performed once the corrections of the spans were made and the purpose was to confirm that the new pipeline configuration along the supported spans had sufficient fatigue life for the temporary and operational phases. For the assessment of all three stages, the probability of occurrence and directionality of the near bottom current was considered to improve prediction of the

  1. Library of Cards: Reconnecting the Scholar and the Library

    Directory of Open Access Journals (Sweden)

    Mita Williams

    2016-03-01

    Full Text Available This paper is based on a presentation I gave at the Access Conference in Toronto, Ontario on September 10th, 2015. Both the presentation and this paper are explorations in three parts. The first part is a short history lesson on the use of paper cards by scholars and librarians, which led to the introduction of the “Scholar’s Box.” The second part asks the question: Can we consider Zotero as the Scholar’s Box of the digital age when it cannot capture important metadata such as linked open data? It is recognized that this is not just a shortcoming of Zotero: research is surprisingly still very difficult to share between scholars, libraries, and writing tools. This is due to an inability to capture the “invisible text” when we copy and paste citations from one application to another. The third part establishes that the digital card is now the dominant design pattern of web and mobile, and notes that these systems are largely restricted to proprietary platforms, which restricts the movement of cards between systems. This paper then suggests how we might transform the historical Scholar’s Box, by using HTML5 index cards from Cardstack.io as a means to bring new forms of sharing on the web, and, in doing so, reconnect the scholar to the library. Cet article est basé sur un exposé que j’ai donné à Access Conference à Toronto le 10 septembre 2015. L’exposé et cet article sont des explorations en trois parties. La première partie est une leçon d’histoire courte sur l’usage des cartes en papier par les spécialistes et les bibliothécaires, qui a mené à l’introduction du “Scholar’s Box”. La seconde partie pose la question: Est-ce que nous pouvons considérer Zotero comme le “Scholar’s Box” de l’âge numérique, même s’il ne peut pas capturer des métadonnées importantes telles que les données liées ouvertes? On reconnaît que ce n’est pas seulement une lacune de Zotero: étonnement, la recherche est

Under their budget constraint, scholars and librarians are struggling for the choice of new medium for obtaining needed information goods and services, traditional publishers are developing operation schemes for electronic access to their intellectual assets, and governments are searching for optimal subsidy policies for acquisition of electronic resources. This study applies traditional economic approaches to scholarly electronic journal publishing. There are four basic economic issues that this study will address: scholars and libraries' demand for sources of scholarly articles, the production and distribution of scholarly journal, scholar electronic journal pricing strategies, and the externalities of shared information goods and services. Part 1 of this three-part article discusses the market economics of scholarly electronic journal publishing business work. It also describes choices among scholars, librarians, and publishers. It provides background for some of economic issues, as well as observations on the impact of new mediums on library resource acquisitions.

    In an effort to achieve the maximum possible Reynolds number (Re) when conducting production testing for flight loads aerodynamic databases, it has been the preferred practice of The Boeing Company / Commercial Airplanes (BCA) -- Loads and Dynamics Group since the early 1990's to test large scale semi-span models in the 11- By 11-Foot Transonic Wind Tunnel (TWT) leg of the Unitary Plan Wind Tunnel (UPWT) at the NASA Ames Research Center (ARC). There are many problems related to testing large scale semi-span models of high aspect ratio flexible transport wings, such as; floor boundary layer effects, wing spanwise wall effects, solid blockage buoyancy effects, floor mechanical interference effects, airflow under the model effects, or tunnel flow gradient effects. For most of these issues, BCA has developed and implemented either standard testing methods or numerical correction schemes and these will not be discussed in this document. Other researchers have reported on semi-span transonic testing correction issues, however most of the reported research has been for low Mach testing. Some of the reports for low Mach testing address the difficult problem of preventing undesirable airflow under a semi-span model while ensuring unrestricted main balance functionality, however, for transonic models this issue has gone unresolved. BCA has been cognizant for sometime that there are marked differences in wing pressure distributions from semi-span transonic model testing than from full model or flight testing. It has been suspected that these differences are at least in part due to airflow under the model. Previous efforts by BCA to address this issue have proven to be ineffective or inconclusive and in one situation resulted in broken hardware. This paper reports on a Boeing-NASA collaborative investigation based on a series of small tests conducted between June 2006 and November 2007 in the 11 by 11 foot Transonic Wind Tunnel at NASA Ames on three large commercial jet

    Full Text Available Nowadays, three most popular citation databases are Web of Science (WoS, Scopus and Google Scholar (GS. In contrast to WoS and Scopus, GS is freely accessible. Comparing the three citation databases, WoS and Scopus have precisely defined and published criteria for selection of sources and papers from these sources. Google’s policy is quite non-transparent. In recent times, however, scientists have been increasingly citing data from GS in addition to data on presence and citations in databases WoS and Scopus. In the conclusion of a comparative analysis of number of citations of papers published in the Croatian Medical Journal in 2005 and 2006 according to the three citation databases, it is emphasized that GS may serve as an alternative bibliometric measure of citation frequency (Šember et al. 2010. An investigation of the number of citations for scientists from the fields of library and information sciences for the period 1996–2005, according to the three mentioned citation databases, has shown, among other things, that citations collected by GS are very useful. They are not of the same quality and significance as those from WoS and Scopus, but they point at a broader international echo of the cited papers than results obtained using WoS and Scopus (Meho, Yang 2007. 

  7. Discourses on sex differences in medieval scholarly Islamic thought.

    Science.gov (United States)

    Gadelrab, Sherry Sayed

    2011-01-01

    This study explores how medical authorities in medieval Islamic society understood and analyzed Greek authorities on the differences between men and women and their mutual contributions to the process of reproduction. As this research illustrates, such thinkers' interpretations of sex differences did not form a consistent corpus, and were in fact complex and divergent, reflecting, and contributing to, the social and cultural constructs of gender taken up by European authors in the Middle Ages. While some scholars have argued for a "one sex" view of human beings in the medieval period, a close reading of Islamic medical authors shows that the plurality and complexity of ideas about sex differences and the acceptance of the flexibility of barriers between the sexes make it difficult to assume that the biological knowledge about sex differences formed a unitary ideological foundation for a system of gender hierarchy. It is clear, however, that whatever their differences, medieval Islamic discussions of sex differences implicitly or explicitly emphasized the inferiority of the female body.

    2006-01-01

    Full Text Available Introduction. This study explored graduate students' information behaviour related to their process of inquiry and scholarly activities. Method. In depth, semi-structured interviews were conducted with one hundred graduate students representing all disciplines and departments from Carnegie Mellon University. Analysis. Working in pairs, we coded transcripts of interviews into meaningful categories using ATLAS.ti software. The combined use of quantitative and qualitative analysis aimed to reduce subjectivity. Results. Graduate students often begin with a meeting with professors who provide direction, recommend and provide resources. Other students help to shape graduate students' research activities, and university library personnel provide guidance in finding resources. The Internet plays a major role, although students continue to use print resources. Convenience, lack of sophistication in finding and using resources and course requirements affect their information behaviour. Findings vary across disciplines and between programmes. Conclusion. Libraries can influence students' information behaviour by re-evaluating their instructional programmes and provision of resources and services. They can take a lead by working with academic staff to guide students.

    2007-01-01

    The large-scale analysis of scholarly artifact usage is constrained primarily by current practices in usage data archiving, privacy issues concerned with the dissemination of usage data, and the lack of a practical ontology for modeling the usage domain. As a remedy to the third constraint, this article presents a scholarly ontology that was engineered to represent those classes for which large-scale bibliographic and usage data exists, supports usage research, and whose instantiation is scalable to the order of 50 million articles along with their associated artifacts (e.g. authors and journals) and an accompanying 1 billion usage events. The real world instantiation of the presented abstract ontology is a semantic network model of the scholarly community which lends the scholarly process to statistical analysis and computational support. We present the ontology, discuss its instantiation, and provide some example inference rules for calculating various scholarly artifact metrics.

    2013-04-01

    This review summarizes several avenues of planning inquiry into food systems research, revealing gaps in the literature, allied fields of study and mismatches between scholarly disciplines and the food system life cycle. Planners and scholars in associated fields have identified and defined problems in the food system as 'wicked' problems, complex environmental issues that require systemic solutions at the community scale. While food justice scholars have contextualized problem areas, planning scholars have made a broad case for planning involvement in solving these wicked problems while ensuring that the functional and beneficial parts of the food system continue to thrive. This review maps the entry points of scholarly interest in food systems and planning's contributions to its study, charting a research agenda for the future.

    Full Text Available Scholarly journals are known as the most important medium for scholarly communication since long time back. As technology transforms the flow of information and idea everywhere, it changes the nature of scholarly communications and publishing of scholarly journals as well. The electronic scholarly publishing rapidly produced an expectation, among researchers of the availability of articles at their desktop, rather than the previous scenario of visiting the library to read a print journal issue. There are lots of technological improvements in electronic journals publishing. The present paper looks at some of technical issues in electronic publishing such as DOI, DOI-X, CrossRef, Citation/Reference Linking, OpenURL, SFX and MetaLib which are being used in the World Wide Web.

    In this paper, using a moving window to scan through every stock price time series over a period from 2 January 2001 to 11 March 2011 and mutual information to measure the statistical interdependence between stock prices, we construct a corresponding weighted network for 501 Shanghai stocks in every given window. Next, we extract its maximal spanning tree and understand the structure variation of Shanghai stock market by analyzing the average path length, the influence of the center node and the p-value for every maximal spanning tree. A further analysis of the structure properties of maximal spanning trees over different periods of Shanghai stock market is carried out. All the obtained results indicate that the periods around 8 August 2005, 17 October 2007 and 25 December 2008 are turning points of Shanghai stock market, at turning points, the topology structure of the maximal spanning tree changes obviously: the degree of separation between nodes increases; the structure becomes looser; the influence of the center node gets smaller, and the degree distribution of the maximal spanning tree is no longer a power-law distribution. Lastly, we give an analysis of the variations of the single-step and multi-step survival ratios for all maximal spanning trees and find that two stocks are closely bonded and hard to be broken in a short term, on the contrary, no pair of stocks remains closely bonded for a long time.

    Background Physicians frequently search PubMed for information to guide patient care. More recently, Google Scholar has gained popularity as another freely accessible bibliographic database. Objective To compare the performance of searches in PubMed and Google Scholar. Methods We surveyed nephrologists (kidney specialists) and provided each with a unique clinical question derived from 100 renal therapy systematic reviews. Each physician provided the search terms they would type into a bibliographic database to locate evidence to answer the clinical question. We executed each of these searches in PubMed and Google Scholar and compared results for the first 40 records retrieved (equivalent to 2 default search pages in PubMed). We evaluated the recall (proportion of relevant articles found) and precision (ratio of relevant to nonrelevant articles) of the searches performed in PubMed and Google Scholar. Primary studies included in the systematic reviews served as the reference standard for relevant articles. We further documented whether relevant articles were available as free full-texts. Results Compared with PubMed, the average search in Google Scholar retrieved twice as many relevant articles (PubMed: 11%; Google Scholar: 22%; P<.001). Precision was similar in both databases (PubMed: 6%; Google Scholar: 8%; P=.07). Google Scholar provided significantly greater access to free full-text publications (PubMed: 5%; Google Scholar: 14%; P<.001). Conclusions For quick clinical searches, Google Scholar returns twice as many relevant articles as PubMed and provides greater access to free full-text articles. PMID:23948488

    2013-01-01

    We study the probabilities with which chordal Schramm-Loewner Evolutions (SLE) visit small neighborhoods of boundary points. We find explicit formulas for general chordal SLE boundary visiting probability amplitudes, also known as SLE boundary zig-zags or order refined SLE multi-point Green's functions on the boundary. Remarkably, an exact answer can be found to this important SLE question for an arbitrarily large number of marked points. The main technique employed is a spin chain - Coulomb gas correspondence between tensor product representations of a quantum group and functions given by Dotsenko-Fateev type integrals. We show how to express these integral formulas in terms of regularized real integrals, and we discuss their numerical evaluation. The results are universal in the sense that apart from an overall multiplicative constant the same formula gives the amplitude for many different formulations of the SLE boundary visit problem. The formula also applies to renormalized boundary visit probabilities f...

    The current study examined delayed recall of items that had been processed during simple and complex span tasks. Three experiments were reported showing that despite more items being recalled initially from a simple span task (i.e., word span) than a complex span task (i.e., operation span), on a delayed recall test more items were recalled that had initially been processed during the complex span task. This delayed recall advantage for items processed during complex span tasks persisted when...

    2014-01-01

    Recent advances in life-sustaining treatments and technologies, have given rise to newly-emerged, critical and sometimes, controversial questions regarding different aspects of end-of-life decision-making and care. Since religious values are among the most influential factors in these decisions, the present study aimed to examine the Islamic scholars' views on end-of-life care. A structured interview based on six main questions on ethical decision-making in end-of-life care was conducted with eight Shiite experts in Islamic studies, and was analyzed through deductive content analysis. Analysis revealed certain points in Islamic views on the definition of death and the persons making decisions about end-of-life care. According to the participants, in addition to conventional criteria ('urf) such as absence of heartbeat and respiration, the irreversible cessation of human voluntary acts (as a sign that the soul has control over the body and the faculty of thinking) are considered to be the criteria in establishing death. The participants also recognized physicians as the main authorities in verifying signs of death. Furthermore, it was emphasized that life preservation and continuation of care must be sensible, and the patient can request not to have death-prolonging procedures started or continued. In the view of participants, patient's autonomy cannot be the sole basis for all measures, but Islamic ethical and jurisprudential principles should be relied upon to make correct and sensible decisions whether to continue or stop terminal patients' care. Final decisions should be made by a team of experts, and physicians must be at the center of such a team. Finally, we suggest that a guideline in keeping with Islamic norms on human life and death, purpose of life, God's will, boundaries of man's authority, and the physician's ethical duties and obligations should be developed.

  1. 复杂悬跨条件下的管线涡激振动分析%VIV analysis of pipelines under complex span conditions

    Institute of Scientific and Technical Information of China (English)

    James WANG; F. Steven WANG; Gang DUAN; Paul JUKES

    2009-01-01

    Spans occur when a pipeline is laid on a rough undulating seabed or when upheaval buckling occurs due to constrained thermal expansion. This not only results in static and dynamic loads on the flowline at span sections, but also generates vortex induced vibration (VIV), which can lead to fatigue issues. The phenomenon, if not predicted and controlled properly, will negatively affect pipeline integrity, leading to expensive remediation and intervention work. Span analysis can be complicated by: long span lengths, a large number of spans caused by a rough seabed, and multi-span interactions. In addition, the complexity can be more onerous and challenging when soil uncertainty, concrete degradation and unknown residual lay tension are considered in the analysis. This paper describes the latest developments and a .state-of-the-art. finite element analysis program that has been developed to simulate the span response of a flowline under complex boundary and loading conditions. Both VIV and direct wave loading are captured in the analysis and the results are sequentially used for the ultimate limit state (ULS) check and fatigue life calculation.

  2. Burnup span sensitivity analysis of different burnup coupling schemes

    International Nuclear Information System (INIS)

    Highlights: ► The objective of this work is the burnup span sensitivity analysis of different coupling schemes. ► Three kinds of schemes have been implemented in a new MCNP–ORIGEN linkage program. ► Two kinds of schemes are based predictor–corrector technique and the third is based on Euler explicit method. ► The analysis showed that the predictor–corrector approach better accounts for nonlinear behavior of burnup. ► It is sufficiently good to use the Euler method at small spans but for large spans use of second order scheme is mandatory. - Abstract: The analysis of core composition changes is complicated by the fact that the time and spatial variations in isotopic composition depend on the neutron flux distribution and vice versa. Fortunately, changes in core composition occur relatively slowly and hence the burnup analysis can be performed by dividing the burnup period into some burnup spans and assuming that the averaged flux and cross sections are constant during each burn up span. The burnup span sensitivity analysis attempts to find how much the burnup spans could be increased without any significant change in results. This goal has been achieved by developing a new MCNP–ORIGEN linkage program named MOBC (MCNP–ORIGEN Burnup Calculation). Three kinds of coupling scheme have been implemented in MOBC. Two of these are based on second order predictor–corrector technique and enable us to choose larger time steps, whilst the third one is based on Euler explicit first order method and is faster than the other two. The validity of the developed program has been evaluated by the code vs. code comparison technique. Two different types of codes are employed. The first one is based on deterministic two dimensional transport method, like CASMO-4 and HELIOS codes, and the second one is based on Monte Carlo method, like MCODE code. Only one coupling technique is employed in each of these state of the art codes, while the MOBC excels in its ability to

  6. Design and operational considerations for unsupported offshore pipeline spans

    Energy Technology Data Exchange (ETDEWEB)

    Shah, B.C.; White, C.N.; Rippon, I.J.

    1988-05-01

    Design and operational considerations have been examined in determining the significance of unsupported offshore pipeline spans that may develop during pipeline installation or field operation. Allowable unsupported span lengths determined during design are generally based on strict code compliance and a design foundation encompassing the worst possible environmental and operational loads. During operation, however, unsupported spans develop beyond the allowable limits, perhaps as a result of various unforseen local conditions. Applying original design criteria is likely to result in cost-prohibitive repair predictions, while lack of action may result in loss of production. Without the design code requirements of an existing or a proposed pipeline system being violated, realistically safe design can be approached through evaluation of the sensitivity of the key design parameters. Priorities for remedial repair of the unsupported spans can be established for the pipelines in service while operating constraints, budget, and schedule are recognized. On the basis of periodic surveys, properly formatted survey data, and reanalysis of the design parameters, pipeline span repair cost estimates and schedules can be appreciably reduced. Similar principles can be applied to a pipeline in planning and design stages to ensure a safe operating design and to eliminate an uneconomically conservative design. These design and operational considerations are illustrated through a case study.

  7. Radiation effects on life span in Caenorhabditis elegans

    Johnson, T.E.; Hartman, P.S.

    1988-09-01

    Wild-type and radiation-sensitive (Rad) mutants of Caenorhabditis elegans were irradiated using a /sup 137/Cs source (2.7 krads/min.) at several developmental stages and subsequently monitored for life span. Acute doses of radiation ranged from 1 krad to 300 krads. All stages required doses above 100 krads to reduce mean life span. Dauers and third stage larvae were more sensitive, and 8-day-old adults were the most resistant. Occasional statistically significant but nonrepeatable increases in survival were observed after intermediate levels of irradiation (10-30 krads). Unirradiated rad-4 and rad-7 had life spans similar to wild-type; all others had a significant reduction in survival. The mutants were about as sensitive as wild-type to the effects of ionizing radiation including occasional moderate life span extensions at intermediate doses. We conclude that the moderate life span extensions sometimes observed after irradiation are likely to be mediated by a means other than the induction of DNA repair enzymes.

  12. Advanced aerostatic analysis of long-span suspension bridges

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    As the span length of suspension bridges increases, the diameter of cables and thus the wind load acting on them, the nonlinear wind-structure interaction and the wind speed spatial non-uniformity all increase consequently, which may have unnegligible influence on the aerostatic behavior of long-span suspension bridges. In this work, a method of advanced aerostatic analysis is presented firstly by considering the geometric nonlinearity, the nonlinear wind-structures and wind speed spatial non-uniformity. By taking the Runyang Bridge over the Yangtze River as example, effects of the nonlinear wind-structure interaction, wind speed spatial non-uniformity, and the cable's wind load on the aerostatic behavior of the bridge are investigated analytically. The results showed that these factors all have important influence on the aerostatic behavior, and should be considered in the aerostatic analysis of long and particularly super long-span suspension bridges.

    Seismic load has a significant effect on the response of a free spanning submarine pipeline when the pipeline is constructed in a seismically active region. The model experiment is performed on an underwater shaking table to simulate the response of submarine pipelines under dynamic input. In consideration of the effects of the terrestrial and submarine pipeline, water depth, support condition, distance from seabed, empty and full pipeline, and span on dynamic response, 120 groups of experiments are conducted. Affecting factors are analyzed and conclnsions are drawn for reference. For the control of dynamic response, the span of a submarine pipeline is by far more important than the other factors. Meanwhile, the rosponse difference between a submarine pipeline under sine excitation and that under random excitation exists in experiments.

    This paper reports the results of a piece of research about long-span suspension bridges with multiple-box girder steel deck characterized by low drag coefficient and high aeroelastic stability. For this type of bridges, by increasing the span length, the contribution to the stiffness of the suspension cables becomes dominant with respect to that of the deck, so that the ratio of the frequency of the first torsional mode to the frequency of the first vertical bending mode approaches unity, wh...

    Shuai, Xin; Rollins, Jason; Custis, Tonya; Schilder, Frank; Edmunds, Mathilda

    2016-01-01

    Over the past few decades, the rate of publication retractions has increased dramatically in academia. In this study, we investigate retractions from a quantitative perspective, aiming to answer two fundamental questions. One, how do retractions influence the scholarly impact of retracted papers, authors, and institutions? Two, does this influence propagate to the wider academic community through scholarly associations? Specifically, we analyzed a set of retracted articles indexed in Thomson Reuters Web of Science (WoS), and ran multiple experiments to compare changes in scholarly impact against a control set of non-retracted articles, authors, and institutions. We further applied the Granger Causality test to investigate whether different scientific topics are dynamically affected by retracted papers occurring within those topics. Our results show two key findings: first, the scholarly impact of retracted papers and authors significantly decreases after retraction, and the most severe impact decrease correla...

    2010-12-01

    Full Text Available Mount Allison University, with about 2,400 students, is a small, undergraduate Liberal Arts and Science university with a long history of faculty-student collaboration in both research and cocurricular activities. In 2005, Mount Allison introduced the Undergraduate Teaching Internship Program in which professors and senior students collaborate in instruction. The program has quickly become for its faculty participants an important springboard for teaching innovation and scholarship. Almost immediately after its introduction, it became clear that the Undergraduate Teaching Internship Program addressed two distinct but overlapping needs—the first was predictable, the second less so: (a it presented opportunities for senior students to develop skills, knowledge and values that transcend those normally associated with undergraduate education; and (b it provided a mechanism whereby faculty could engage in scholarly reflection on teaching and Scholarship of Teaching and Learning projects. In the 5 years since its inception, internship has become not simply a peripheral program but a strong thread woven into the fabric of the university culture. While outlining some constraints of the program, this descriptive paper explains the many ways in which internship has resulted in productive, mutually beneficial collaborations between interns and their supervising professors, encouraging an even more pervasive dialogue about teaching.L’Université Mount Allisson est un petit établissement qui offre des cours dans les domaines des arts et des sciences à environ 2400 étudiants de premier cycle.

    The nurse scholar, whether a supervisor, an educator, or a practitioner, has a lifetime of research opportunities as well as personal experiences related to the human need for humor. We need to develop the means to assess the individual's and group's response to humor. Nurse scholars, particularly the nurse supervisor, can make a significant contribution in the search to harness some of the energy we use in laughing and direct it toward helping us heal our human conditions.

  11. 1-Skeletons of the Spanning Tree Problems with Additional Constraints

    Directory of Open Access Journals (Sweden)

    V. A. Bondarenko

    2015-01-01

    Full Text Available In this paper, we study polyhedral properties of two spanning tree problems with additional constraints. In the first problem, it is required to find a tree with a minimum sum of edge weights among all spanning trees with the number of leaves less than or equal to a given value. In the second problem, an additional constraint is the assumption that the degree of all nodes of the spanning tree does not exceed a given value. The recognition versions of both problems are NP-complete. We consider polytopes of these problems and their 1-skeletons. We prove that in both cases it is a NP-complete problem to determine whether the vertices of 1-skeleton are adjacent. Although it is possible to obtain a superpolynomial lower bounds on the clique numbers of these graphs. These values characterize the time complexity in a broad class of algorithms based on linear comparisons. The results indicate a fundamental difference between combinatorial and geometric properties of the considered problems from the classical minimum spanning tree problem.

    2004-01-01

    We introduce a new definition of measure-theoretic pressure for ergodic measures of continuous maps on a compact metric space. This definition is similar to those of topological pressure involving spanning sets. As an application, for C1+α(α> 0) diffeomorphisms of a compact manifold, we study the relationship between the measure-theoretic pressure and the periodic points.

  15. Building scholarly writing capacity in the doctor of nursing practice program.

    Science.gov (United States)

    Shirey, Maria R

    2013-01-01

    This article discusses a systematic teaching/learning approach to scholarly writing in the doctor of nursing practice program. The SMART Approach to building scholarly writing capacity in nursing consists of Strategies, Methods, and Assessment of Outcomes, Related to Teaching/Learning. The strategies include reiterating standards of excellence, building the discipline, dispelling fears, empowering with knowledge, facilitating independence, and celebrating excellence. Methods include scholarly writing assessment, planning and structure, evaluation and feedback, doing and redoing, mentoring for publication, and reiterating knowledge dissemination. The SMART Approach can achieve six key outcomes. Students who experience the developmental approach become stronger writers, and they achieve better course grades. Student evaluations of teaching suggest that this developmental approach is valuable, and faculty teaching is rated highly. Following manuscript development, students understand the relationship between didactic content and mentored activities that promote scholarly writing independence. Students learn that every professional activity provides a potential writing experience. Scholarly writing in nursing is a necessary skill set that can be learned. The SMART Approach to building scholarly writing capacity in nursing is effective because it uses a "guide by the side" approach as compared with traditional "sage on stage" principles.

    Science.gov (United States)

    Cabezas-Clavijo, A; Delgado-López-Cózar, E

    2013-01-01

    The aim of this study is to review the features, benefits and limitations of the new scientific evaluation products derived from Google Scholar, such as Google Scholar Metrics and Google Scholar Citations, as well as the h-index, which is the standard bibliometric indicator adopted by these services. The study also outlines the potential of this new database as a source for studies in Biomedicine, and compares the h-index obtained by the most relevant journals and researchers in the field of intensive care medicine, based on data extracted from the Web of Science, Scopus and Google Scholar. Results show that although the average h-index values in Google Scholar are almost 30% higher than those obtained in Web of Science, and about 15% higher than those collected by Scopus, there are no substantial changes in the rankings generated from one data source or the other. Despite some technical problems, it is concluded that Google Scholar is a valid tool for researchers in Health Sciences, both for purposes of information retrieval and for the computation of bibliometric indicators.

    Main, Paul; Irish, Bill; Paulo, Shara; Curtis, Anthony

    2013-01-01

    The introduction of the Education Scholarship and Education Fellowship programmes in the Severn Deanery in 2008 was in response to an emergent need for a more formalised career structure for the most able GPSTs and specifically for identified education scholars to progress over time from a scholar to temporary and substantive training programme director (TPD) posts. As a result, two scholars have progressed to being appointed as fellows (one-year fixed-term TPDs) over the last three years and one of these is now a TPD. This qualitative research study sought to identify the value and acceptance of the scholar scheme within the Severn Deanery and in particular assess the impact of the scholar scheme in terms of educational benefits, impact on professional practice and future career opportunities. It also undertook to examine the key factors affecting the quality of experience of the scholar scheme (e.g.induction, mentorship, autonomous vs. prescribed education opportunities etc.). Findings showed unequivocal and universal support for the scheme. PMID:23356764

    The historical reanalysis dataset generated by NOAA ESRL and the University of Colorado CIRES, the Twentieth Century Reanalysis version 2 (20CRv2), is a comprehensive global atmospheric circulation dataset spanning 1871-2012, assimilating only surface pressure and using monthly Hadley Centre SST and sea ice distributions (HadISST1.1) as boundary conditions. It has been made possible through collaboration with GCOS, WCRP, and the ACRE initiative. It is chiefly motivated by a need to provide an observational validation dataset, with quantified uncertainties, for assessments of climate model simulations of the 20th century, with emphasis on the statistics of daily weather. It uses, together with an NCEP global numerical weather prediction (NWP) land/atmosphere model to provide background "first guess" fields, an Ensemble Kalman Filter (EnKF) data assimilation method. This yields a global analysis every 6 hours as the most likely state of the atmosphere, and also yields the uncertainty of that analysis. Improvements in the new version ("2c") include an extension back to 1850 and the specification of new boundary conditions. These come from new fields of monthly COBE-SST2 sea ice concentrations and an ensemble of daily Simple Ocean Data Assimilation with Sparse Input (SODAsi.2c) sea surface temperatures. SODAsi.2c itself was forced with 20CR, allowing these boundary conditions to be more consistent with the atmospheric reanalysis. Millions of additional pressure observations contained in the new International Surface Pressure Databank version 3 are also included. These improvements result in 20CR version "2c" having comparable or better analyses, as suggested by improved 24 hour forecast skill, more realistic uncertainty in near-surface air temperature, and a reduction in spurious centennial trends in the tropical and polar regions. An intercomparison with ERA-Interim, MERRA, and JRA-55 reanalyses that assimilate all available upper-air and satellite observations will

    1997-08-01

    The use of active feedback compensation to mitigate cutting instabilities in an advanced milling machinspan>e is discussed in this paper. A linear structural model delineating dynamics significant to the onset of cutting instabilities was combined with a nonlinear cutting model to form a dynamic depiction of an existing milling machinspan>e. The model was validated with experimental data. Modifications made to an existing machine model were used to predict alterations in dynamics due to the integration of active feedback compensation. From simulations, subcomponent requirements were evaluated and cutting enhancements were predicted. Active compensation was shown to enable more than double the metal removal rate over conventional milling machines. 25 refs., 10 figs., 1 tab.

    2016-06-01

    We demonstrate a system based on telecom components for the generation of a coherent octave-spanning supercontinuum from a continuous-wave laser. The system utilizes direct multiplication of a 10 GHz signal derived from a commercial synthesizer to carve pulses from the laser, which are then iteratively chirped and compressed in two stages. After reducing the repetition rate of the resulting pulse train to 2.5 GHz using selective transmission through an electro-optic gate, propagation through highly-nonlinear fiber generates an octave-spanning supercontinuum spectrum. We discuss the impact of the noise of the modulation frequency on the coherence of the supercontinuum and discuss its mitigation. Close agreement between experiment and theory is shown throughout, and we use our ability to precisely model the experiment to propose an extension of the system to 20 GHz repetition rate.

    2008-01-01

    Long-span aircraft hangars have features which differ from other large structural systems. The temperature stresses due to temperature variations often greatly impact the mechanical performance of the structure. The paper presents an analysis of the heat transfer processes and factors which influence the temperature distribution. The AMECO-A380 aircraft hangar at the Beijing Capital International Airport was selected as a practical example to illustrate the use of finite volume analysis to calculate the temperature field taking into account meteorological conditions, solar radiation, heat convection, etc. The temperature distribution and the variation of the length of the upper and lower chords of the grid structure roof were ana-lyzed to develop guidelines for the temperature distributions in very large aircraft hangars. The results show that the temperature effect will be large for long-span hangars, and the temperature stresses due to non-uniform temperatures should be analyzed to guarantee the structural safety of large aircraft hangars.

Thus, professionals are increasingly expected to engage in boundary spanning activities in order to facilitate inter-organizational and inter-sectoral collaboration....... However, this task can be difficult for individual actors and it is important to investigate the work and challenges of boundary spanners in various settings. This study explores the challenges related to a new boundary spanning role for general practitioners employed to facilitate collaboration between...... and distinct categories covering the different types of challenges experienced by the informants. Results: The main challenges of the general practitioners acting as boundary spanners were: 1) defining and negotiating the role in terms of tasks and competencies; 2) representing and mobilizing colleagues...

  20. A Vesicle Superpool Spans Multiple Presynaptic Terminals in Hippocampal Neurons

    Synapse-specific vesicle pools have been widely characterized at central terminals. Here, we demonstrate a vesicle pool that is not confined to a synapse but spans multiple terminals. Using fluorescence imaging, correlative electron microscopy, and modeling of vesicle dynamics, we show that some recycling pool vesicles at synapses form part of a larger vesicle "superpool." The vesicles within this superpool are highly mobile and are rapidly exchanged between terminals (turnover: similar to 4%...

  1. Minocycline Effect on Life and Health Span of Drosophila Melanogaster

    Up-regulation of kynurenine (KYN) pathway of tryptophan (TRP) was suggested as one of the mechanisms of aging and aging-associated disorders. Genetic and pharmacological impairment of TRP – KYN metabolism resulted in prolongation of life span in Drosophila models. Minocycline, an antibiotic with anti-inflammatory, antioxidant and neuroprotective properties independent of its antibacterial activity, inhibited KYN formation from TRP. Since minocycline is the only FDA approved for human use medi...

    We compute the complexity of two infinite families of finite graphs: the Sierpi\\'{n}ski graphs, which are finite approximations of the well-known Sierpi\\'nsky gasket, and the Schreier graphs of the Hanoi Towers group $H^{(3)}$ acting on the rooted ternary tree. For both of them, we study the weighted generating functions of the spanning trees, associated with several natural labellings of the edge sets.

  4. Computation of Boundary Layers

    2004-11-01

    Full Text Available This paper is the first part of a series of studies where we examine several methods for the solution of the boundary layer equation of the fluid mechanics. The first of these is the analytical or rather quasi analytical method due to Blasius. This method reduces a system of partial differential equations to a system of ordinary differential equations and these in turn are solved by numerical methods since no exact solution of the Blasius type equations is known. We determind all the Blasius equation neccessary for up to 11-th order approximation. Our further aim to study the finite difference numerical solutions of the boundary layer equation and some of the methods applying weighted residual principles and by comparing these with the ”exact” solutions arrived at by Blasius method develop a quick reliable method for solving the boundary layer equation.

  5. Free-boundary equilibria

    International Nuclear Information System (INIS)

    A self-contained MHD description of the Helias class stellarators is obtained by determining appropriate external currents (coils) producing the Helias vacuum field and by the subsequent computing of the free-boundary equilibrium. Coil configurations are calculated with the NESCOIL code, the free-boundary equilibrium is studied via the NEMEC code, which combines the 3D fixed-boundary VMEC code and the NESTOR code for determining the vacuum field surrounding the plasma. Results for the 5081 Helias configuration, being considered for the W VII-X device are shown. The 5081 is a five-period device with aspect ratio 10 and a rotational transform between 0.8 and 1.0. It is MHD stable up to a beta value of 0.05

    Labeling of sentence boundaries is a necessary prerequisite for many natural language processing tasks, including part-of-speech tagging and sentence alignment. End-of-sentence punctuation marks are ambiguous; to disambiguate them most systems use brittle, special-purpose regular expression grammars and exception rules. As an alternative, we have developed an efficient, trainable algorithm that uses a lexicon with part-of-speech probabilities and a feed-forward neural network. After training for less than one minute, the method correctly labels over 98.5\\% of sentence boundaries in a corpus of over 27,000 sentence-boundary marks. We show the method to be efficient and easily adaptable to different text genres, including single-case texts.

    The mechanical behavior of lipid bilayers spanning the pores of highly ordered porous silicon substrates was scrutinized by local indentation experiments as a function of surface functionalization, lipid composition, solvent content, indentation velocity, and pore radius. Solvent-containing nano black lipid membranes (nano-BLMs) as well as solvent-free pore-spanning bilayers were imaged by fluorescence and atomic force microscopy prior to force curve acquisition, which allows distinguishing between membrane-covered and uncovered pores. Force indentation curves on pore-spanning bilayers attached to functionalized hydrophobic porous silicon substrates reveal a predominately linear response that is mainly attributed to prestress in the membranes. This is in agreement with the observation that indentation leads to membrane lysis well below 5% area dilatation. However, membrane bending and lateral tension dominate over prestress and stretching if solvent-free supported membranes obtained from spreading giant liposomes on hydrophilic porous silicon are indented. An elastic regime diagram is presented that readily allows determining the dominant contribution to the mechanical response upon indentation as a function of load and pore radius. PMID:19453196

    2015-01-01

    Full Text Available The paper explored some empirical patterns of time span being set up in various natural branches of science for their being conceptually incompatible with the patterns in the theoretic (academic physics, and considered the concept of "functional" time span as well that relieved the above contradiction. The author stated in the paper that biologists, physiologists, psychologists, sociologists, economists, etc. have been involved into the efforts to set up the above patterns, to solve their research-and-occupation-related issues upon their own criteria derived from their understanding of academic and practical appropriateness of their work rather than with the criteria the physics suggested.The author has paid much attention to the way the functional concept of timespan operated, which relieved conceptual incompatibility existing between the empirical patterns of time span and the pattern set up in the theoretic (academic physics. This concept enables significant alteration to a perception of a position and part taken by the cognisant self (represented in the physics as "an observer" in the academic concept, in order to extend it, by means of selfdetermination, with the conception of a " perceiver position/ standing". This conception, in its turn, shall be defined by the set of factors of various origin, ranging from those produced by an individual mind to those shaped with societal ideology, all of them encouraging a researcher to select out of the series of properties observed of an entity explored exactly the features "substantial" for study, and not the other.

  11. Sector spanning agrifood process transparency with Direct Computer Mapping

    2010-11-01

    Full Text Available Agrifood processes are built from multiscale, time-varied networks that span many sectors from cultivation, through animal breeding, food industry and trade to the consumers. The sector spanning traceability has not yet been solved, because neither the“one-step backward, one-step forward” passing of IDs, nor the large sophisticated databases give a feasible solution. In our approach, the transparency of process networks is based on the generic description of dynamic mass balances. The solution of this,apparently more difficult task, makes possible the unified acquisition of the data from the different ERP systems, and the scalable storage of these simplified process models. Inaddition, various task specific intensive parameters (e.g. concentrations, prices, etc. can also be carried with the mass flows. With the knowledge of these structured models, theplanned Agrifood Interoperability Centers can serve tracing and tracking results for the actors and for the public authorities. Our methodology is based on the Direct Computer Mapping of process models. The software is implemented in open source code GNUPrologand C++ languages. In the first, preliminary phase we have studied a couple of consciously different realistic actors, as well as an example for the sector spanning chain,combined from these realistic elements.

  12. What does it means to be a critical scholar? A metalogue between science education doctoral students

    2016-04-01

    This manuscript is written in response to Lydia Burke and Jesse Bazzul's article Locating a space of criticality as new scholars in science education. As doctoral students finding our place in the culture of science education, we respond by discussing our journeys towards the development of a scholarly identity, with particular focus on whether or how we see ourselves as critical scholars. Since each of us authoring this paper has a different perspective, a metalogue format is utilized to ensure all of our voices and journeys are represented. We use the Burke and Bazzul article as a platform for conversations about challenges faced for emerging scholars in the field of science education and explore how we see our role in responding to these challenges. Specifically, we discuss the barriers to publication, dissemination of research to practitioners, and how to approach these problems from a grounding in critical theory. As a result of our conversations, we conclude that there is a need to reshape the field of science education to invite more unorthodox research perspectives, methodologies, and publication formats. To do so, the issues we explore require a continued conversation between emerging scholars, practicing researchers, and practicing educators.

    Priem, Jason; Hemminger, Bradley M

    2012-01-01

    In growing numbers, scholars are integrating social media tools like blogs, Twitter, and Mendeley into their professional communications. The online, public nature of these tools exposes and reifies scholarly processes once hidden and ephemeral. Metrics based on this activities could inform broader, faster measures of impact, complementing traditional citation metrics. This study explores the properties of these social media-based metrics or "altmetrics", sampling 24,331 articles published by the Public Library of Science. We find that that different indicators vary greatly in activity. Around 5% of sampled articles are cited in Wikipedia, while close to 80% have been included in at least one Mendeley library. There is, however, an encouraging diversity; a quarter of articles have nonzero data from five or more different sources. Correlation and factor analysis suggest citation and altmetrics indicators track related but distinct impacts, with neither able to describe the complete picture of scholarly use alo...

    Big data research is currently split on whether and to what extent Twitter can be characterised as an informational or social network. We contribute to this line of inquiry through an investigation of digital humanities scholars' uses and gratifications of Twitter. We conducted a thematic analysis of 25 semistructured interview transcripts to learn about these scholars' professional use of Twitter. Our findings show that Twitter is considered a critical tool for informal communication within DH invisible colleges, functioning at varying levels as both an informational network (learning to 'Twitter' and maintaining awareness) and a social network (imagining audiences and engaging other digital humanists). We find that Twitter follow relationships reflect common academic interests and are closely tied to scholars' preexisting social ties and conference or event co-attendance. The concept of the invisible college continues to be relevant but requires revisiting. The invisible college formed on Twitter is messy, ...

  7. The eye-voice span during reading aloud

    Directory of Open Access Journals (Sweden)

    Jochen eLaubrock

    2015-09-01

    Full Text Available Although eye movements during reading are modulated by cognitive processing demands, they also reflect visual sampling of the input, and possibly preparation of output for speech or the inner voice. By simultaneously recording eye movements and the voice during reading aloud, we obtained an output measure that constrains the length of time spent on cognitive processing. Here we investigate the dynamics of the eye-voice span (EVS, the distance between eye and voice. We show that the EVS is regulated immediately during fixation of a word by either increasing fixation duration or programming a regressive eye movement against the reading direction. EVS size at the beginning of a fixation was positively correlated with the likelihood of regressions and refixations. Regression probability was further increased if the EVS was still large at the end of a fixation: if adjustment of fixation duration did not sufficiently reduce the EVS during a fixation, then a regression rather than a refixation followed with high probability. We further show that the EVS can help understand cognitive influences on fixation duration during reading: in mixed model analyses, the EVS was a stronger predictor of fixation durations than either word frequency or word length. The EVS modulated the influence of several other predictors on single fixation durations. For example, word-N frequency effects were larger with a large EVS, especially when word N-1 frequency was low. Finally, a comparison of single fixation durations during oral and silent reading showed that reading is governed by similar principles in both reading modes, although EVS maintenance and articulatory processing also cause some differences. In summary, the eye-voice span is regulated by adjusting fixation duration and/or by programming a regressive eye movement when the eye-voice span gets too large. Overall, the EVS appears to be directly related to updating of the working memory buffer during reading.

    In this lecture we will consider the minimum weight spanning tree (MST) problem, i.e., one of the simplest and most vital combinatorial optimization problems. We will discuss a particular greedy algorithm that allows to compute a MST for undirected weighted graphs, namely Kruskal's algorithm, and we will study the structure of MSTs obtained for weighted scale free random graphs. This is meant to clarify whether the structure of MSTs is sensitive to correlations between edge weights and topology of the underlying scale free graphs.

    Using the method of spectral decimation and a modified version of Kirchhoff's matrix-tree theorem, a closed form solution to the number of spanning trees on approximating graphs to a fully symmetric self-similar structure on a finitely ramified fractal is given in theorem 3.4. We show how spectral decimation implies the existence of the asymptotic complexity constant and obtain some bounds for it. Examples calculated include the Sierpiński gasket, a non-post critically finite analog of the Sierpiński gasket, the Diamond fractal, and the hexagasket. For each example, the asymptotic complexity constant is found.

    2016-01-01

    The dynamical phenomena of complex networks are very difficult to predict from local information due to the rich microstructures and corresponding complex dynamics. On the other hands, it is a horrible job to compute some stochastic parameters of a large network having thousand and thousand nodes. We design several recursive algorithms for finding spanning trees having maximal leaves (MLS-trees) in investigation of topological structures of Sierpinski growing network models, and use MLS-trees to determine the kernels, dominating and balanced sets of the models. We propose a new stochastic method for the models, called the edge-cumulative distribution, and show that it obeys a power law distribution.

  13. Emotional Egocentricity Bias across the life-span

    Directory of Open Access Journals (Sweden)

    Federica eRiva

    2016-04-01

    Full Text Available In our daily lives, we often have to quickly estimate the emotions of our conspecifics in order to have successful social interactions. While this estimation process seems quite easy when we are ourselves in a neutral or equivalent emotional state, it has recently been shown that in case of incongruent emotional states between ourselves and the others, our judgments can be biased. This phenomenon, introduced to the literature with the term Emotional Egocentricity Bias (EEB, has been found to occur in young adults and, to a greater extent, in children. However, how EEB changes across the life-span from adolescence to old age has been largely unexplored. In this study, we recruited 114 female participants subdivided in four cohorts (adolescents, young adults, middle-aged adults, older adults to examine EEB age-related changes. Participants were administered with a paradigm which, by making use of visuo-tactile stimulation that elicits conflicting feelings in paired participants, allows the valid and reliable exploration of EEB. Results highlighted a U-shaped relation between age and EEB, revealing higher emotional egocentricity in adolescents and older adults compared to young and middle-aged adults. These results are in line with the neuroscientific literature which has recently shown that overcoming EEB is associated with a greater activation of a portion of the parietal lobe, namely the right Supramarginal Gyrus (rSMG. This is an area that reaches full maturation only by the end of adolescence, and displays an early decay in older age. Thus, the age-related changes of the EEB could be possibly due to the life-span development of the rSMG. This study is the first one to show the quadratic relation between age and the EEB and set a milestone for further research exploring the neural correlates of the life-span development of the EEB. Future studies are needed in order to generalize these results to the male population and to explore gender

  14. Fluorofluorophores: fluorescent fluorous chemical tools spanning the visible spectrum.

    Science.gov (United States)

    Sletten, Ellen M; Swager, Timothy M

    2014-10-01

    "Fluoro" refers to both fluorescent and fluorinated compounds. Despite the shared prefix, there are very few fluorescent molecules that are soluble in perfluorinated solvents. This paucity is surprising, given that optical microscopy is a ubiquitous technique throughout the physical sciences and the orthogonality of fluorous materials is a commonly exploited strategy in synthetic chemistry, materials science, and chemical biology. We have addressed this shortage by synthesizing a panel of "fluorofluorophores," fluorescent molecules containing high weight percent fluorine with optical properties spanning the visible spectrum. We demonstrate the utility of these fluorofluorophores by preparing fluorescent perfluorocarbon nanoemulsions. PMID:25229987

Local damages in bridges, which are characterized by an horizontal load transfer system, may progress along the deck or along the suspension system, as the dynamic overloading of the structural elements immediately adjacent to the failed...... ones may lead to subsequent failures. In suspension bridges, which are characterized by a relatively low continuity of the system, the damage of the deck may favor a collapse standstill, in case of an early detachment of the deck collapsing section. In the paper, a long span suspension bridge is taken...

    Habel, Florian; Shirvanyan, Vage; Trubetskov, Michael; Burger, Christian; Sommer, Annkatrin; Kling, Matthias F; Schultze, Martin; Pervak, Vladimir

    2016-05-01

    A novel concept for octave spanning dispersive mirrors with low spectral dispersion oscillations is presented. The key element of the so-called wedge dispersive mirror is a slightly wedged layer which is coated on a specially optimized dispersive multilayer stack by a common sputter coating process. The group delay dispersion (GDD) of a pulse reflected on a wedge dispersive mirror is nearly free of oscillations. Fabricated mirrors with negative GDD demonstrate the compression of a pulse down to 3.8 fs as good as double angled mirrors optimized for the same bandwidth. PMID:27137538

  19. Grain Boundary Segregation in Metals

    CERN Document Server

    Lejcek, Pavel

    2010-01-01

    Grain boundaries are important structural components of polycrystalline materials used in the vast majority of technical applications. Because grain boundaries form a continuous network throughout such materials, their properties may limit their practical use. One of the serious phenomena which evoke these limitations is the grain boundary segregation of impurities. It results in the loss of grain boundary cohesion and consequently, in brittle fracture of the materials. The current book deals with fundamentals of grain boundary segregation in metallic materials and its relationship to the grain boundary structure, classification and other materials properties.

  20. Quantum gravitational effects on boundary

    CERN Document Server

    Park, I Y

    2016-01-01

    Quantum gravitational effects may hold the key to some of the outstanding problems in theoretical physics. In this work we analyze the perturbative quantum effects on the boundary of a gravitational system and Dirichlet boundary condtion imposed at the classical level. Our analysis reveals that for a black hole solution there exists a clash between the quantum effects and Dirichlet boundary condition: the solution of the one-particle-irreducible (1PI) action no longer obeys the Dirichlet boundary condition. The analysis also suggests that the violation of the Dirichlet boundary condition should be tied with a certain mechanism of information storage on the boundary.

  3. Reactor pressure boundary materials

    International Nuclear Information System (INIS)

    With a long-term operation of nuclear power plants, the component materials are degraded under severe reactor conditions such as neutron irradiation, high temperature, high pressure and corrosive environment. It is necessary to establish the reliable and practical technologies for improving and developing the component materials and for evaluating the mechanical properties. Especially, it is very important to investigate the technologies for reactor pressure boundary materials such as reactor vessel and pipings in accordance with their critical roles. Therefore, this study was focused on developing and advancing the microstructural/micro-mechanical evaluation technologies, and on evaluating the neutron irradiation characteristics and radiation effects analysis technology of the reactor pressure boundary materials, and also on establishing a basis of nuclear material property database

    A simple relation between inhomogeneous transfer matrices and boundary quantum Knizhnik-Zamolodchikov (KZ) equations is exhibited for quantum integrable systems with reflecting boundary conditions, analogous to an observation by Gaudin for periodic systems. Thus, the boundary quantum KZ equations receive a new motivation. We also derive the commutativity of Sklyanin’s boundary transfer matrices by merely imposing appropriate reflection equations, in particular without using the conditions of crossing symmetry and unitarity of the R-matrix.

In order to position complexity theory as a plausible alternative to autopoiesis I discuss the differing understanding of boundary within each theory, and use this as a vehicle to critique autopoiesis. My critique is situated within systems theory thinking but is external to both autopoiesis and complexity theory (although I must oscillate betwee...

  6. The open boundary equation

    Directory of Open Access Journals (Sweden)

    D. Diederen

    2015-06-01

    Full Text Available We present a new equation describing the hydrodynamics in infinitely long tidal channels (i.e., no reflection under the influence of oceanic forcing. The proposed equation is a simple relationship between partial derivatives of water level and velocity. It is formally derived for a progressive wave in a frictionless, prismatic, tidal channel with a horizontal bed. Assessment of a large number of numerical simulations, where an open boundary condition is posed at a certain distance landward, suggests that it can also be considered accurate in the more natural case of converging estuaries with nonlinear friction and a bed slope. The equation follows from the open boundary condition and is therefore a part of the problem formulation for an infinite tidal channel. This finding provides a practical tool for evaluating tidal wave dynamics, by reconstructing the temporal variation of the velocity based on local observations of the water level, providing a fully local open boundary condition and allowing for local friction calibration.

  7. Contribution of adipose tissue to health span and longevity.

    Huffman, Derek M; Barzilai, Nir

    2010-01-01

    Adipose tissue accounts for approximately 20% (lean) to >50% (in extreme obesity) of body mass and is biologically active through its secretion of numerous peptides and release and storage of nutrients such as free fatty acids. Studies in rodents and humans have revealed that body fat distribution, including visceral fat (VF), subcutaneous (SC) fat and ectopic fat are critical for determining the risk posed by obesity. Specific depletion or expansion of the VF depot using genetic or surgical strategies in animal models has proven to have direct effects on metabolic characteristics and disease risk. In humans, there is compelling evidence that abdominal obesity most strongly predicts mortality risk, while in rats, surgical removal of VF improves mean and maximum life span. There is also growing evidence that fat deposition in ectopic depots such as skeletal muscle and liver can cause lipotoxicity and impair insulin action. Conversely, expansion of SC adipose tissue may confer protection from metabolic derangements by serving as a 'metabolic sink' to limit both systemic lipids and the accrual of visceral and ectopic fat. Treatments targeting the prevention of fat accrual in these harmful depots should be considered as a primary target for improving human health span and longevity. PMID:20703052

  8. Quantifying yeast chronological life span by outgrowth of aged cells.

    Murakami, Christopher; Kaeberlein, Matt

    2009-01-01

    The budding yeast Saccharomyces cerevisiae has proven to be an important model organism in the field of aging research. The replicative and chronological life spans are two established paradigms used to study aging in yeast. Replicative aging is defined as the number of daughter cells a single yeast mother cell produces before senescence; chronological aging is defined by the length of time cells can survive in a non-dividing, quiescence-like state. We have developed a high-throughput method for quantitative measurement of chronological life span. This method involves aging the cells in a defined medium under agitation and at constant temperature. At each age-point, a sub-population of cells is removed from the aging culture and inoculated into rich growth medium. A high-resolution growth curve is then obtained for this sub-population of aged cells using a Bioscreen C MBR machine. An algorithm is then applied to determine the relative proportion of viable cells in each sub-population based on the growth kinetics at each age-point. This method requires substantially less time and resources compared to other chronological lifespan assays while maintaining reproducibility and precision. The high-throughput nature of this assay should allow for large-scale genetic and chemical screens to identify novel longevity modifiers for further testing in more complex organisms. PMID:19421136

  9. Homeless Aging Veterans in Transition: A Life-Span Perspective

    Directory of Open Access Journals (Sweden)

    Carla J. Thompson

    2013-01-01

    Full Text Available The need for counseling and career/educational services for homeless veterans has captured political and economic venues for more than 25 years. Veterans are three times more likely to become homeless than the general population if veterans live in poverty or are minority veterans. This mixed methods study emphasized a life-span perspective approach for exploring factors influencing normative aging and life-quality of 39 homeless veterans in Alabama and Florida. Seven descriptive quantitative and qualitative research questions framed the investigation. Study participants completed a quantitative survey reflecting their preferences and needs with a subset of the sample (N=12 also participating in individual qualitative interview sessions. Thirty-two service providers and stakeholders completed quantitative surveys. Empirical and qualitative data with appropriate triangulation procedures provided interpretive information relative to a life-span development perspective. Study findings provide evidence of the need for future research efforts to address strategies that focus on the health and economic challenges of veterans before they are threatened with the possibility of homelessness. Implications of the study findings provide important information associated with the premise that human development occurs throughout life with specific characteristics influencing the individual’s passage. Implications for aging/homelessness research are grounded in late-life transitioning and human development intervention considerations.

  12. Building a scholar in writing (BSW): A model for developing students' critical writing skills.

    Science.gov (United States)

    Bailey, Annette; Zanchetta, Margareth; Velasco, Divine; Pon, Gordon; Hassan, Aafreen

    2015-11-01

    Several authors have highlighted the importance of writing in developing reflective thinking skills, transforming knowledge, communicating expressions, and filling knowledge gaps. However, difficulties with higher order processing and critical analysis affect students' ability to write critical and thoughtful essays. The Building a Scholar in Writing (BSW) model is a 6-step process of increasing intricacies in critical writing development. Development of critical writing is proposed to occur in a processed manner that transitions from presenting simple ideas (just bones) in writing, to connecting ideas (connecting bones), to formulating a thesis and connecting key components (constructing a skeleton), to supporting ideas with evidence (adding muscle), to building creativity and originality (adding essential organs), and finally, developing strong, integrated, critical arguments (adding brain). This process symbolically represents the building of a scholar. The idea of building a scholar equates to progressively giving life and meaning to a piece of writing with unique scholarly characteristics. This progression involves a transformation in awareness, thinking, and understanding, as well as advancement in students' level of critical appraisal skills.

    2008-02-01

    The evolution of the electronic age has led to the development of numerous medical databases on the World Wide Web, offering search facilities on a particular subject and the ability to perform citation analysis. We compared the content coverage and practical utility of PubMed, Scopus, Web of Science, and Google Scholar. The official Web pages of the databases were used to extract information on the range of journals covered, search facilities and restrictions, and update frequency. We used the example of a keyword search to evaluate the usefulness of these databases in biomedical information retrieval and a specific published article to evaluate their utility in performing citation analysis. All databases were practical in use and offered numerous search facilities. PubMed and Google Scholar are accessed for free. The keyword search with PubMed offers optimal update frequency and includes online early articles; other databases can rate articles by number of citations, as an index of importance. For citation analysis, Scopus offers about 20% more coverage than Web of Science, whereas Google Scholar offers results of inconsistent accuracy. PubMed remains an optimal tool in biomedical electronic research. Scopus covers a wider journal range, of help both in keyword searching and citation analysis, but it is currently limited to recent articles (published after 1995) compared with Web of Science. Google Scholar, as for the Web in general, can help in the retrieval of even the most obscure information but its use is marred by inadequate, less often updated, citation information.

    2010-03-01

    An increasing number of medical schools have implemented or are considering implementing scholarly activity programs as part of their undergraduate medical curricula. The goal of these programs is to foster students' analytical skills, enhance their self-directed learning and their oral and written communication skills, and ultimately to train better physicians. In this article, the authors describe the approach to implementing scholarly activities at a school that requires this activity and at a school where it is elective. Both programs have dealt with significant challenges including orienting students to a complex activity that is fundamentally different than traditional medical school courses and clerkships, helping both students and their mentors understand how to "stay on track" and complete work, especially during the third and fourth years, and educating students and mentors about the responsible conduct of research, especially involving human participants. Both schools have found the implementation process to be evolutionary, requiring experience before faculty could significantly improve processes. A required scholarly activity has highlighted the need for information technology (IT) support, including Web-based document storage and student updates, as well as automatic e-mails alerting supervisory individuals to student activity. Directors of the elective program have found difficulty with both ensuring uniform outcomes across different areas of study and leadership changes in a process that has been largely student-driven. Both programs have found that teamwork, regular meetings, and close communication have helped with implementation. Schools considering the establishment of a scholarly activity should consider these factors when designing programs.

  3. Apprenticeship in Scholarly Publishing: A Student Perspective on Doctoral Supervisors’ Roles

    Directory of Open Access Journals (Sweden)

    2015-02-01

    Full Text Available Although a large body of literature has suggested that doctoral supervisors play an important role in their students’ attempts at scholarly publishing, few studies have focused specifically on what roles they play. This study sought to address this gap by zooming in on the various roles a group of Chinese doctoral students found their supervisors playing in their scholarly publishing endeavors. Our analysis revealed four important roles played by the supervisors: ‘prey’ searchers, managers, manuscript correctors and masters. The results showed that the supervisors not only facilitated the doctoral students’ publishing output, but also fostered their apprenticeship in scholarly publishing and the academic community. However, the results also unveiled a general unavailability of sorely-needed detailed and specific guidance on students’ early publishing attempts and some supervisors’ limited ability to correct students’ English manuscripts. These findings underscore the important contributions doctoral supervisors can make to their students’ academic socialization. They also suggest a need for external editorial assistance with doctoral students’ English manuscripts and ample opportunities for their scaffolded initiation into the tacit conventions and practices of scholarly publishing.
