    Izmailian, N. Sh.; Kenna, R.

    2015-02-01

    We express the partition functions of the spanning tree on finite square lattices under five different sets of boundary conditions in terms of a principal partition function with twisted-boundary conditions. Based on these expressions, we derive the exact asymptotic expansions of the logarithm of the partition function for each case. We have also established several groups of identities relating spanning-tree partition functions for the different boundary conditions. We also explain an apparent discrepancy between logarithmic correction terms in the free energy for a two-dimensional spanning-tree model with periodic and free-boundary conditions and conformal field theory predictions. We have obtained corner free energy for the spanning tree under free-boundary conditions in full agreement with conformal field theory predictions.

  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. Through integrating Western astronomy with indigenous tradition while exorcising the otherness contained within the cultural package

    Full Text Available Like manufacturing companies, hotels implement several strategies in order to satisfy consumers’ needs and wants. These strategies play critical roles in the context of unique characteristics of hotel services and interaction between boundary spanning role employee and consumer, when they are examined from the service firms’ perspectives. Having outlined this basic information, managerial ethical behaviors are assumed to depict relationships with frontline employees’ motivation and job satisfaction. In light of the aforementioned information, this study aims to make boundary spanning role employees assess the managerial ethical behaviors. Therefore, Managerial Ethical Behavior and Job Satisfaction Survey was conducted with 836 frontline employees in four and five star hotels in Adana. The reliability and validity dimensions of the scale were taken into consideration so as to be capable of obtaining reasonable results and making contribution to the related literature. Frequency tests and means were employed, and regression analysis was used to investigate the effect of managerial ethical behavior on employees’ motivation and job satisfaction. Managerial ethical behavior has positive effects on both employees' motivation and their job satisfaction. And as expected, employees motivation has positive and moderate effect on their job satisfaction in the subject 4 and 5 Star hotel companies

  6. 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. PMID:23050573

  7. 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.

    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...

    2012-01-01

    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...

    From 2005-2006, scholarly publishing, including e-publishing, becomes one of several criteria used by The Ministry of Education and Science in financing research in Norwegian universities and colleges. Based on qualitative methodology and critical case sampling of recent Norwegian policy documents and reports, combined with typical case sampling of articles on e-publishing 2000-2005, especially from D-Lib magazine (Patton, 2002; Hawkins, 2001), the article discusses trends in Norwegian schola...

  6. Uniform random spanning trees

    OpenAIRE

    Pemantle, Robin

    2004-01-01

    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?

    CERN, the European Organization for Nuclear Research, has operated an institutional preprint repository for more than 10 years. The repository contains over 850,000 records of which more than 450,000 are full-text OA preprints, mostly in the field of particle physics, and it is integrated with the library's holdings of books, conference proceedings, journals and other grey literature. In order to encourage effective propagation and open access to scholarly material, CERN is implementing a range of innovative library services into its document repository: automatic keywording, reference extraction, collaborative management tools and bibliometric tools. Some of these services, such as user reviewing and automatic metadata extraction, could make up an interesting testbed for future publishing solutions and certainly provide an exciting environment for e-science possibilities. The future protocol for scientific communication should naturally guide authors towards OA publication and CERN wants to help reach a full...

    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.

    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 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.

    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.

    The rate at which scholarly literature is being produced has been increasing at approximately 3.5 percent per year for decades. This means that during a typical 40 year career the amount of new literature produced each year increases by a factor of four. The methods scholars use to discover relevant literature must change.

Two decades ago, this discovery process essentially consisted of paging through abstract books, talking to colleagues and librarians, and browsing journals. A time-consuming process, which could even be longer if material had to be shipped from elsewhere. Now much of this discovery process is mediated by online scholarly information systems. 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.

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.

    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.

  9. 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

  10. 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.

    Full Text Available Almost two years after the formation of SPARC Europe, the LIBER pre-conference seminar in St Petersburg gave an excellent opportunity to review progress on the road to achieving the aims of SPARC Europe. The traditional models of scholarly communication are increasingly being shown to be antiquated and insufficiently flexible to adapt to the new environment. SPARC Europe calls for far reaching changes in the way we approach scholarly communications. The talks in the seminar provide snapshots of the changing environment. They highlight the activities being taken at all levels by a wide variety of stakeholders in the scholarly communications process: Small and society publishers are developing alternatives to inflexible and restrictive 'Big Deals'; funding bodies and research organisations worldwide are becoming aware of issues surrounding scholarly communication; institutional repositories are providing new communications channels; and libraries are investigating new directions and taking on new roles. This paper will expand on some of these recent developments.

    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

    Science.gov (United States)

    Faraj, Samer; Yan, Aimin

    2009-05-01

    The purpose of this article is to promote an open systems perspective on team research. The authors develop a model of team boundary activities: boundary spanning, buffering, and reinforcement. The model examines the relationship between these boundary activities and team performance, the moderating effects of organizational contextual factors, and the mediating effect of team psychological safety on the boundary work-performance relationship. These relationships were empirically tested with data collected from 64 software development teams. Boundary spanning, buffering, and boundary reinforcement were found to relate to team performance and psychological safety. Both relationships are moderated by the team's task uncertainty and resource scarcity. The implications of the findings are offered for future research and practice. PMID:19450002

    Operating in Alberta, KeySpan is a gas processing company with 14 gas plant facilities and pipelines in the province. Since its employees are sometimes working at remote locations, it has been difficult to use conventional classroom and seminar learning techniques to meet training needs. 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.

    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

  10. Becoming University Scholars: Inside Professional Autoethnographies

    Directory of Open Access Journals (Sweden)

    Fernando Hernández

    2010-01-01

    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.

  11. Octave-spanning semiconductor laser

    CERN Document Server

    Rösch, Markus; Beck, Mattias; Faist, Jérôme

    2014-01-01

    We present here a semiconductor injection laser operating in continuous wave with an emission covering more than one octave in frequency, and displaying homogeneous power distribution among the lasing modes. The gain medium is based on a heterogeneous quantum cascade structure operating in the THz range. Laser emission in continuous wave takes place from 1.64 THz to 3.35 THz with optical powers in the mW range and more than 80 modes above threshold. Free-running beatnote investigations on narrow waveguides with linewidths of 980 Hz limited by jitter indicate frequency comb operation on a spectral bandwidth as wide as 624 GHz, making such devices ideal candidates for octave-spanning semiconductor-laser-based THz frequency combs.

    2005-01-01

    Working with tree graphs is always easier than with loopy ones and spanning trees are the closest tree-like structures to a given graph. We find a correspondence between the solutions of random K-satisfiability problem and those of spanning trees in the associated factor graph. We introduce a modified survey propagation algorithm which returns null edges of the factor graph and helps us to find satisfiable spanning trees. This allows us to study organization of satisfiable spanning trees in t...

  17. The role of gender in scholarly authorship

    CERN Document Server

    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...

  4. Can Scholarly Communication be Evidence Based? (Editorial

    Directory of Open Access Journals (Sweden)

    2010-12-01

    Full Text Available This issue of Evidence Based Library and Information Practice includes three papers from the Evidence Based Scholarly Communication Conference (EBSCC that took place in March 2010i. 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

  5. Extended attention span training system

    Science.gov (United States)

    Pope, Alan T.; Bogart, Edward H.

    1991-01-01

    Attention Deficit Disorder (ADD) is a behavioral disorder characterized by the inability to sustain attention long enough to perform activities such as schoolwork or organized play. Treatments for this disorder include medication and brainwave biofeedback training. Brainwave biofeedback training systems feed back information to the trainee showing him how well he is producing the brainwave pattern that indicates attention. The Extended Attention Span Training (EAST) system takes the concept a step further by making a video game more difficult as the player's brainwaves indicate that attention is waning. The trainee can succeed at the game only by maintaining an adequate level of attention. The EAST system is a modification of a biocybernetic system that is currently being used to assess the extent to which automated flight management systems maintain pilot engagement. This biocybernetic system is a product of a program aimed at developing methods to evaluate automated flight deck designs for compatibility with human capabilities. The EAST technology can make a contribution in the fields of medical neuropsychology and neurology, where the emphasis is on cautious, conservative treatment of youngsters with attention disorders.

  13. 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.

    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.

    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.

  1. Node degree distribution in spanning trees

    International Nuclear Information System (INIS)

    A method is presented for computing the number of spanning trees involving one link or a specified group of links, and excluding another link or a specified group of links, in a network described by a simple graph in terms of derivatives of the spanning-tree generating function defined with respect to the eigenvalues of the Kirchhoff (weighted Laplacian) matrix. The method is applied to deduce the node degree distribution in a complete or randomized set of spanning trees of an arbitrary network. An important feature of the proposed method is that the explicit construction of spanning trees is not required. It is shown that the node degree distribution in the spanning trees of the complete network is described by the binomial distribution. Numerical results are presented for the node degree distribution in square, triangular, and honeycomb lattices. (paper)

    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.

  11. 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.

    This book introduces readers to the novel concept of variable span speech enhancement filters, and demonstrates how it can be used for effective noise reduction in various ways. Further, the book provides the accompanying Matlab code, allowing readers to easily implement the main ideas discussed....... Variable span filters combine the ideas of optimal linear filters with those of subspace methods, as they involve the joint diagonalization of the correlation matrices of the desired signal and the noise. The book shows how some well-known filter designs, e.g. the minimum distortion, maximum signal......-to-noise ratio, Wiener, and tradeoff filters (including their new generalizations) can be obtained using the variable span filter framework. It then illustrates how the variable span filters can be applied in various contexts, namely in single-channel STFT-based enhancement, in multichannel enhancement in both...

  15. Spanning and independence properties of frame partitions

    CERN Document Server

    Bodmann, Bernhard G; Paulsen, Vern I; Speegle, Darrin

    2010-01-01

    We answer a number of open problems in frame theory concerning the decomposition of frames into linearly independent and/or spanning sets. We prove that in finite dimensional Hilbert spaces, Parseval frames with norms bounded away from 1 can be decomposed into a number of sets whose complements are spanning, where the number of these sets only depends on the norm bound. We also prove, assuming the Kadison-Singer conjecture is true, that this holds for infinite dimensional Hilbert spaces. Further, we prove a stronger result for Parseval frames whose norms are uniformly small, which shows that in addition to the spanning property, the sets can be chosen to be independent, and the complement of each set to contain a number of disjoint, spanning sets.

  16. Elevated histone expression promotes life span extension.

    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.

    The probability distribution for the number of top to bottom spanning clusters in Directed percolation in two and three dimensions appears to be universal and is of the form $P(n) \\sim \\exp(-\\alpha n^2)$. We argue that $\\alpha$ is a new critical quantity vanishing at the upper critical dimension. The probability distribution of the individual masses of the spanning clusters is found to have a Pearson distribution with a lower cutoff. Various properties of the clusters are reported.

  16. Peripheral scholarly journals: From locality to globality

    Directory of Open Access Journals (Sweden)

    Françoise Salager-Meyer

    2015-11-01

    Full Text Available This critical literature review examines the problems faced by scholarly peripheral journals. Two categories of problems were identified. The first one refers to the deleterious effect the “publish-or-perish” mantra has on those journals, such as publication drain and the conduction of research that appeals to an international audience. The second category consists in problems that are related to the context in which these journals are published: lack of funds to run the journals, lack of competent editors and reviewers, problems related to publication ethics, endogamy, etc. The solution to overcome such problems is not to publish more and more journals in peripheral countries – which has been the tendency for the last ten years or so – but to upgrade local journals to global ones that should be published online in order to attract high-quality papers from both national and foreign authors. This would strengthen and enhance these journals visibility and international indexing. It would also increase the global influence of the research conducted in peripheral countries and bring global awareness to the specific scientific, social, cultural and economic features prevailing in such contexts.

    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

  4. Boundary Layer

    Loitsianskii. L. G.

    1956-01-01

    The fundamental, practically the most important branch of the modern mechanics of a viscous fluid or a gas, is that branch which concerns itself with the study of the boundary layer. The presence of a boundary layer accounts for the origin of the resistance and lift force, the breakdown of the smooth flow about bodies, and other phenomena that are associated with the motion of a body in a real fluid. The concept of boundary layer was clearly formulated by the founder of aerodynamics, N. E. Joukowsky, in his well-known work "On the Form of Ships" published as early as 1890. In his book "Theoretical Foundations of Air Navigation," Joukowsky gave an account of the most important properties of the boundary layer and pointed out the part played by it in the production of the resistance of bodies to motion. The fundamental differential equations of the motion of a fluid in a laminar boundary layer were given by Prandtl in 1904; the first solutions of these equations date from 1907 to 1910. As regards the turbulent boundary layer, there does not exist even to this day any rigorous formulation of this problem because there is no closed system of equations for the turbulent motion of a fluid. Soviet scientists have done much toward developing a general theory of the boundary layer, and in that branch of the theory which is of greatest practical importance at the present time, namely the study of the boundary layer at large velocities of the body in a compressed gas, the efforts of the scientists of our country have borne fruit in the creation of a new theory which leaves far behind all that has been done previously in this direction. We shall herein enumerate the most important results by Soviet scientists in the development of the theory of the boundary layer.

    2013-01-01

    New tools for measuring the impact of research (altmetrics) bring much needed attention to changing scholarly communication practices. However, alternative forms of output are still widely excluded from the evaluation of individual researchers. The ACUMEN project addresses this problem in two ways. First, by creating a researcher portfolio framework that facilitates promotion of a broad range of scholarly output. And second, by shifting the orientation of evaluations from a top-down relations...

    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.

  5. 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 $SG_{2,b}$.

  10. Spanning trees and the Eurozone crisis

    Science.gov (United States)

    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.

    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.

    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.

    Full Text Available Information is cornerstone of research. The research scholars were solely dependable on librarycollection for satisfying their research needs before the birth of the Internet. However, with theintroduction of the online sources, there are evidences of departure from total reliance on printcollection to the online information. This online information is stored in various digital archives;available in many formats and retrieved through different search tools by applying varioussearch techniques. The scholars need to be literate about these digital archives, formats andsearch tools and techniques. The present study was conducted to how far the social sciencescholars’ are aware and make use of online sources, search tools and techniques. The study wasconducted on social science scholars of the University of Kashmir, Jammu & Kashmir, Indiacarrying the M.Phil. & Ph.D. research programmes. The survey method was applied to conductthe study and questionnaire was used as a data collection tool. The results reveal that majority ofthe scholars are aware and make use of search engines and OPACs whereas majority of themaren’t aware of other search facilities like gateways (subject/regional, directories, meta-search engines and deep Web search tools. The findings also depict that excluding phrase searching, all the scholars aren’t aware and make use other search techniques like field searching, keyword searching, Boolean Operators and truncation methods. The findings also reveal that majority of the scholars are aware and highly make use of JSTOR, JCCC/UGC Consortium and Directory of Open Access Journals (DOAJ respectively whereas other sources like Directory of Open Access Repositories (OpenDOAR, Project Muse, Questia, Ebrary, EBSCOHOST aren’t used adequately due to illiteracy. At the end the suggestions are recommended to enhance online searching skills of the scholars.

    2015-08-01

    Community organizations addressing health and human service needs generally have minimal capacity for research and evaluation. As a result, they are often inadequately equipped to independently carry out activities that can be critical for their own success, such as conducting needs assessments, identifying best practices, and evaluating outcomes. Moreover, they are unable to develop equitable partnerships with academic researchers to conduct community-based research. This paper reports on the progress of the Community Research Scholar Initiative (CRSI), a program that aims to enhance community research and evaluation capacity through training of selected employees from Greater Cleveland community organizations. The intensive 2-year CRSI program includes didactic instruction, fieldwork, multiple levels of community and academic engagement, leadership training, and a mentored research project. The first cohort of CRSI Scholars, their community organizations, and other community stakeholders have incorporated program lessons into their practices and operations. The CRSI program evaluation indicates: the importance of careful Scholar selection; the need to engage executive leadership from Scholar organizations; the value of a curriculum integrating classwork, fieldwork, and community engagement; and the need for continual scholar skill and knowledge assessment. These findings and lessons learned guide other efforts to enhance community organization research and evaluation capacity. PMID:26073663

    The atomic bomb survivors life-span study (LSS) is often claimed to support the linear no-threshold hypothesis (LNTH) of radiation carcinogenesis. This paper shows that this claim is baseless. The LSS data are equally or better described by an s-shaped dependence on radiation exposure with a threshold of about 0.3 Sievert (Sv) and saturation level at about 1.5 Sv. A Monte-Carlo simulation of possible LSS outcomes demonstrates that, given the weak statistical power, LSS cannot provide support ...

    A considerable amount of uncertainty surrounds life expectancy, the average length of life. The standard deviation in adult life span is about 15 years in the U.S., and theory and evidence suggest it is costly. I calibrate a utility-theoretic model of preferences over length of life and show that one less year in standard deviation is worth about half a mean life year. Differences in the standard deviation exacerbate cross-sectional differences in life expectancy between the U.S. and other in...

    In the minimum cost spanning tree model we consider decentralized pricing rules, i.e. rules that cover at least the ecient cost while the price charged to each user only depends upon his own connection costs. We de ne a canonical pricing rule and provide two axiomatic characterizations. First......, the canonical pricing rule is the smallest among those that improve upon the Stand Alone bound, and are either superadditive or piece-wise linear in connection costs. Our second, direct characterization relies on two simple properties highlighting the special role of the source cost....

  3. 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...

    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.

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

    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.

  7. Variable Span Filters for Speech Enhancement

    Jensen, Jesper Rindom; Benesty, Jacob; Christensen, Mads Græsbøll

    2016-01-01

    In this work, we consider enhancement of multichannel speech recordings. Linear filtering and subspace approaches have been considered previously for solving the problem. The current linear filtering methods, although many variants exist, have limited control of noise reduction and speech...... distortion. Subspace approaches, on the other hand, can potentially yield better control by filtering in the eigen-domain, but traditionally these approaches have not been optimized explicitly for traditional noise reduction and signal distortion measures. Herein, we combine these approaches by deriving...... optimal filters using a joint diagonalization as a basis. This gives excellent control over the performance, as we can optimize for noise reduction or signal distortion performance. Results from real data experiments show that the proposed variable span filters can achieve better performance than existing...

  8. Life span study report, 11, part 2

    International Nuclear Information System (INIS)

    ABCC and its successor, RERF, have followed since 1959 and retrospectively to 1950 the mortality in a fixed cohort of survivors of the atomic bombings of Hiroshima and Nagasaki, the so-called Life Span Study sample. The present study, the 11th in a series that began in 1961, extends the surveillance period three more years and covers the period 1950-85. It is based on the recently revised dose system, called DS86, that has replaced previous estimates of individual exposures. The impact of the change from the old system of dosimetry, the T65DR, to the new on the dose-response relationships for cancer mortality was described in the first of this series of reports. Here, the focus is on cancer mortality among the 76,000 A-bomb survivors within the LSS sample for whom DS86 doses have been estimated, with the emphasis on biological issues associated with radiation carcinogenesis.

    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.

  8. Scholarly social media profiles and libraries: A review

    Directory of Open Access Journals (Sweden)

    Judit Ward

    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.

    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

  11. A comprehensive survey of retracted articles from the scholarly literature.

    Directory of Open Access Journals (Sweden)

    Michael L Grieneisen

    Full Text Available BACKGROUND: The number of retracted scholarly articles has risen precipitously in recent years. Past surveys of the retracted literature each limited their scope to articles in PubMed, though many retracted articles are not indexed in PubMed. To understand the scope and characteristics of retracted articles across the full spectrum of scholarly disciplines, we surveyed 42 of the largest bibliographic databases for major scholarly fields and publisher websites to identify retracted articles. This study examines various trends among them. RESULTS: We found, 4,449 scholarly publications retracted from 1928-2011. Unlike Math, Physics, Engineering and Social Sciences, the percentages of retractions in Medicine, Life Science and Chemistry exceeded their percentages among Web of Science (WoS records. Retractions due to alleged publishing misconduct (47% outnumbered those due to alleged research misconduct (20% or questionable data/interpretations (42%. This total exceeds 100% since multiple justifications were listed in some retraction notices. Retraction/WoS record ratios vary among author affiliation countries. Though widespread, only miniscule percentages of publications for individual years, countries, journals, or disciplines have been retracted. Fifteen prolific individuals accounted for more than half of all retractions due to alleged research misconduct, and strongly influenced all retraction characteristics. The number of articles retracted per year increased by a factor of 19.06 from 2001 to 2010, though excluding repeat offenders and adjusting for growth of the published literature decreases it to a factor of 11.36. CONCLUSIONS: Retracted articles occur across the full spectrum of scholarly disciplines. Most retracted articles do not contain flawed data; and the authors of most retracted articles have not been accused of research misconduct. Despite recent increases, the proportion of published scholarly literature affected by retraction

  13. 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.

  14. Atomic Bomb Survivors Life-Span Study

    Dobrzyński, Ludwik

    2015-01-01

    The atomic bomb survivors life-span study (LSS) is often claimed to support the linear no-threshold hypothesis (LNTH) of radiation carcinogenesis. This paper shows that this claim is baseless. The LSS data are equally or better described by an s-shaped dependence on radiation exposure with a threshold of about 0.3 Sievert (Sv) and saturation level at about 1.5 Sv. A Monte-Carlo simulation of possible LSS outcomes demonstrates that, given the weak statistical power, LSS cannot provide support for LNTH. Even if the LNTH is used at low dose and dose rates, its estimation of excess cancer mortality should be communicated as 2.5% per Sv, i.e., an increase of cancer mortality from about 20% spontaneous mortality to about 22.5% per Sv, which is about half of the usually cited value. The impact of the “neutron discrepancy problem” – the apparent difference between the calculated and measured values of neutron flux in Hiroshima – was studied and found to be marginal. Major revision of the radiation risk assessment paradigm is required. PMID:26673526

  15. 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

    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?

    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 oversupply of postdoctoral scholars relative to available faculty positions has led to calls for better assessment of career outcomes. Here, we report the results of a study of postdoctoral outcomes at the University of California, San Francisco, and suggest that institutions have an obligation to determine where their postdoc alumni are employed and to share this information with current and future trainees. Further, we contend that local efforts will be more meaningful than a national survey, because of the great variability in training environment and the classification of postdoctoral scholars among institutions. We provide a framework and methodology that can be adopted by others, with the goal of developing a finely grained portrait of postdoctoral career outcomes across the United States. PMID:27152650

    2014-01-01

    Bibliometrics has moved well beyond the mere tracking of bibliographic citations. The web enables new ways to measure scholarly productivity and impact, making available tools and data that can reveal patterns of intellectual activity and impact that were previously invisible: mentions, acknowledgments, endorsements, downloads, recommendations, blog posts, tweets. This book describes recent theoretical and practical advances in metrics-based research, examining a variety of alternative metrics -- or "altmetrics" -- while also considering the ethical and cultural consequences of relying on metrics to assess the quality of scholarship. Once the domain of information scientists and mathematicians, bibliometrics is now a fast-growing, multidisciplinary field that ranges from webometrics to scientometrics to influmetrics. The contributors to Beyond Bibliometrics discuss the changing environment of scholarly publishing, the effects of open access and Web 2.0 on genres of discourse, novel analytic methods, and the e...

  7. 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.

    Although graduate students are increasingly expected to publish before graduation, they are rarely offered formal education in the full range of the scholarly communication process in their discipline. They quickly learn how to do the research and to present their findings in a format suitable for submission to an academic peer-reviewed journal, but seldom do they (or their faculty advisors) understand the business of publishing and how that may affect their ability to get published.

    Full Text Available Curriculum is a set of planned tasks, learning experiences and behaviors proposed by an authority to achieve predetermined goals in form of behavioral change, academic achievements and learning outcomes within a particular time. 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.

    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

    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.

    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.

    Full Text Available Problem: Programs that encourage scholarly activities beyond the core curriculum and traditional biomedical research are now commonplace among US medical schools. Few studies have generated outcome data for these programs. The goal of the present study was to address this gap. Intervention: The Scholarly Concentration (SC Program, established in 2006 at the Warren Alpert Medical School of Brown University, is a 4-year elective program that not only encourages students to pursue scholarly work that may include traditional biomedical research but also seeks to broaden students’ focus to include less traditional areas. We compared characteristics and academic performance of SC students and non-SC students for the graduating classes of 2010–2014. Context: Approximately one-third of our students opt to complete an SC during their 4-year undergraduate medical education. Because this program is additional to the regular MD curriculum, we sought to investigate whether SC students sustained the academic achievement of non-SC students while at the same time producing scholarly work as part of the program. Outcome: Over 5 years, 35% of students elected to enter the program and approximately 81% of these students completed the program. The parameters that were similar for both SC and non-SC students were age at matriculation, admission route, proportion of undergraduate science majors, and number of undergraduate science courses. Most academic indicators, including United States Medical Licensing Examinations scores, were similar for the two groups; however, SC students achieved more honors in the six core clerkships and were more likely to be inducted into the medical school's two honor societies. Residency specialties selected by graduates in the two groups were similar. SC students published an average of 1.3 peer-reviewed manuscripts per student, higher than the 0.8 manuscripts per non-SC student (p=0.013. Conclusions: An elective, interdisciplinary

    OBJECTIVE To estimate whether there is a gender difference in scholarly productivity among academic gynecologic oncologists. METHODS In this cross-sectional study, the academic rank and gender of gynecologic oncology faculty in the United States were determined from online residency and fellowship directories and departmental web sites. Each individual’s h-index and years of publication were determined from Scopus (a citation database of peer-reviewed literature). The h-index is a quantification of an author’s scholarly productivity that combines the number of publications with the number of times the publications have been cited. We generated descriptive statistics and compared rank, gender, and productivity scores. RESULTS Five hundred seven academic faculty within 137 U.S. teaching programs were identified. Of these, 215 (42%) were female and 292 (58%) were male. Men had significantly higher median h-indices than women, 16 compared with 8, respectively (P<.001). Women were more likely to be of junior academic rank with 63% of assistant professors being female compared with 20% of full professors. When stratifying h-indices by gender and academic rank, men had significantly higher h-indices at the assistant professor level (7 compared with 5, P<.001); however, this difference disappeared at the higher ranks. Stratifying by the years of active publication, there was no significant difference between genders. CONCLUSION Female gynecologic oncologists at the assistant professor level had lower scholarly productivity than men; however, at higher academic ranks, they equaled their male counterparts. Women were more junior in rank, had published for fewer years, and were underrepresented in leadership positions. PMID:26551177

    Sperlich, Anja; Meixner, Johannes; Laubrock, Jochen

    2016-06-01

    The perceptual span is a standard measure of parafoveal processing, which is considered highly important for efficient reading. Is the perceptual span a stable indicator of reading performance? What drives its development? Do initially slower and faster readers converge or diverge over development? Here we present the first longitudinal data on the development of the perceptual span in elementary school children. Using the moving window technique, eye movements of 127 German children in three age groups (Grades 1, 2, and 3 in Year 1) were recorded at two time points (T1 and T2) 1year apart. Introducing a new measure of the perceptual span, nonlinear mixed-effects modeling was used to separate window size effects from asymptotic reading performance. Cross-sectional differences were well replicated longitudinally. Asymptotic reading rate increased monotonously with grade, but in a decelerating fashion. A significant change in the perceptual span was observed only between Grades 2 and 3. Together with results from a cross-lagged panel model, this suggests that the perceptual span increases as a consequence of relatively well-established word reading. Stabilities of observed and predicted reading rates were high after Grade 1, whereas the perceptual span was only moderately stable for all grades. Comparing faster and slower readers as assessed at T1, in general, a pattern of stable between-group differences emerged rather than a compensatory pattern; second and third graders even showed a Matthew effect in reading rate and the perceptual span, respectively.

    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.

    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

    Full Text Available 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.

    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

  9. Mating System Transitions Drive Life Span Evolution in Pristionchus Nematodes.

    2016-04-01

    Interactions between the sexes influence evolution at many scales, but not all animal species conform to the familiar male-female (dioecious) mating system; such taxa are powerful tools for studying the evolutionary importance of sexual selection and conflict on all manner of life-history traits, including longevity. We tested for an effect of mating system on adult life span in Pristionchus nematodes, where self-fertile hermaphrodites have replaced females multiple times independently throughout the genus (androdioecy). By measuring adult life span for 11 species (6 dioecious, 5 androdioecious), we found that life span is considerably shorter in hermaphrodites relative to closely related females. This effect is not a cost of reproduction; brood size did not reliably trade off with life span in self-fertilizing hermaphrodites or in mated females. Furthermore, we found that sexual dimorphism in life span varied among dioecious species, with females generally outliving males. Finally, we documented intraspecific variation for life span and cuticular disease (blistering) prevalence in Pristionchus pacificus, a model system for evolutionary-developmental biology. This work demonstrates that mating system transitions and life span evolution are linked in Pristionchus nematodes and provides a foundation for future comparative and mechanistic studies of aging in this genus.

  10. 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.

    A research study was conducted in order to quantify and analyze the amount of pseudorange multipath at continuous Global Positioning System (CGPS) stations spanning Mexico. These CGPS stations are administered by a variety of organizations, including government agencies and public universities, and thus serve a wide range of positioning needs. Despite the diversity of the networks and their intended audiences, a core function of all of the networks is to provide a stable framework for high-precision positioning in support of diverse commercial and scientific applications. CGPS data from a large number of publicly available networks located in Mexico were studied. These include the RGNA (National Active Geodetic Network) administered by INEGI (National Institute of Statistics and Geography), the PBO network (Plate Boundary Observatory) funded by the National Science Foundation (NSF) and operated by UNAVCO (University NAVstar Consortium), the Southern California Integrated GPS Network (SCIGN), which is a collaboration effort of the United States Geological Survey (USGS), Scripps Institution of Oceanography and the Jet Propulsion Laboratory (JPL), the UNAM network, operated by the National Seismological System (SSN) and the Institute of Geophysics of the National Autonomous University of Mexico (UNAM), the Suominet Geodetic Network (SNG) and the CORS (Continuously Operating Reference Station) network, operated by the Federal Aviation Administration (FAA). A total of 54 CGPS stations were evaluated, where dual-frequency geodetic-grade receivers collected GPS data continuously during the period from 1994 to 2013. It is usually assumed that despite carefully selected locations, all CGPS stations are to some extent, affected by the presence of signal multipath. In addition, the geographic distribution of stations provides a nation-wide access to the International Terrestrial Reference Frame (ITRF).

    .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......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...... between competencies within the organisation; and boundaries between various physical locations of work, in particular between what is done in the office and what is done on site. Maintaining and changing boundaries are the processes through which a particular community sustains its identity and practice...

  14. Rigid supersymmetry with boundaries

    International Nuclear Information System (INIS)

    We construct rigidly supersymmetric bulk-plus-boundary actions, both in x-space and in superspace. For each standard supersymmetric bulk action a minimal supersymmetric bulk-plus-boundary action follows from an extended F- or D-term formula. Additional separately supersymmetric boundary actions can be systematically constructed using co-dimension one multiplets (boundary superfields). We also discuss the orbit of boundary conditions which follow from the Euler-Lagrange variational principle. (orig.)

  15. Popular and/or Prestigious? Measures of Scholarly Esteem

    CERN Document Server

    Ding, Ying

    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.

    Engaging new clinical providers in the HIV workforce is a critical need due to rapidly evolving treatment paradigms, aging out of existing providers, and special population needs. The 1-year competency-based Clinician Scholar Program for minority-serving providers with limited HIV care experience was individually tailored for each provider (n = 74), mostly nurse practitioners, physicians, and clinical pharmacists. Baseline and endpoint self-assessments of clinical knowledge and skills showed significant improvements in all 11 targeted competencies, particularly in managing antiretroviral medications, screening and testing methods, incorporating prevention into HIV care, understanding risk reduction methods, and describing current care standards. Faculty mentor assessments also showed significant improvement in most competencies. Additional benefits included ongoing access to mentorship and training, plus sustained engagement in local and statewide HIV care networks. Our intensive mentoring program model is replicable in other AIDS Education and Training Centers and in other structured training programs. PMID:26253024

    2014-09-01

    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.

  19. Investigation of Seal-to-Floor Effects on Semi-Span Transonic Models

    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

    2016-01-01

    In this work, a new way to represent Japanese animation (anime) is presented. We applied a minimum spanning tree to show the relation between anime. The distance between anime is calculated through three similarity measurements, namely crew, score histogram, and topic similarities. Finally the centralities are also computed to reveal the most significance anime. The result shows that the minimum spanning tree can be used to determine the similarity anime. Furthermore, by using centralities ca...

  5. 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

    Jan Steyaert

    2011-12-01

    Full Text Available Scholarly communication and social work in the Google era In this text, we outline how new media has an impact on international scholarly communication and focus on how these changes (can influence the traditional gap between research and practice. We do so by describing the dreams of yesterday, the facts of today and the possible consequences for the near future. The most significant development on the interface between science and information technology is not so much the increased computational power but the increased availability of scientific information, be it communication between scientists through virtual libraries or discussion lists, or between scientists and students through electronic learning environments. Through this development of more digital scientific communication and more visibility of that communication in the public realm, the traditional schism between science and practice changes. Combining this with the increasing plea for more applicability of research results, it is time to supplement the science citation index with the Google citation index. Onderzoekscommunicatie in sociaal werk in het Google tijdperk In dit artikel zetten we uiteen hoe de opkomst van nieuwe media van invloed is op communicatie tussen wetenschappers wereldwijd, en hoe deze veranderingen van invloed (kunnen zijn op het traditionele gat tussen wetenschap en praktijk. We doen dit door het beschrijven van de dromen van gisteren, de feiten van vandaag de dag en de mogelijke consequenties daarvan voor de toekomst. De belangrijkste ontwikkeling die zich op het raakvlak van wetenschap en informatietechnologie heeft voorgedaan, is niet zozeer de toename in technische mogelijkheden, maar vooral de toegenomen beschikbaarheid van wetenschappelijke informatie, zij het communicatie tussen wetenschappers binnen de virtuele omgeving van bibliotheken of op discussiefora op het internet, of communicatie tussen wetenschappers en studenten middels een elektronische

  7. Burnup span sensitivity analysis of different burnup coupling schemes

    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

  11. 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.

  12. Development of the NTF-117S Semi-Span Balance

    Lynn, Keith C.

    2010-01-01

    A new high-capacity semi-span force and moment balance has recently been developed for use at the National Transonic Facility at the NASA Langley Research Center. This new semi-span balance provides the NTF a new measurement capability that will support testing of semi-span test models at transonic high-lift testing regimes. Future testing utilizing this new balance capability will include active circulation control and propulsion simulation testing of semi-span transonic wing models. The NTF has recently implemented a new highpressure air delivery station that will provide both high and low mass flow pressure lines that are routed out to the semi-span models via a set high/low pressure bellows that are indirectly linked to the metric end of the NTF-117S balance. A new check-load stand is currently being developed to provide the NTF with an in-house capability that will allow for performing check-loads on the NTF-117S balance in order to determine the pressure tare affects on the overall performance of the balance. An experimental design is being developed that will allow for experimentally assessing the static pressure tare affects on the balance performance.

    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.

    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.

    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.

    Telomeric DNA repeats are lost as normal somatic cells replicate. When telomeres reach a critically short length, a DNA damage signal is initiated, inducing cell senescence. Some studies have indicated that telomere length correlates with mortality, suggesting that telomere length contributes to human life span; however, other studies report no correlation, and thus the issue remains controversial. Domestic dogs show parallels in telomere biology to humans, with similar telomere length, telomere attrition, and absence of somatic cell telomerase activity. Using this model, we find that peripheral blood mononuclear cell (PBMC) telomere length is a strong predictor of average life span among 15 different breeds (p Dogs lose telomeric DNA ~10-fold faster than humans, which is similar to the ratio of average life spans between these species. Breeds with shorter mean telomere lengths show an increased probability of death from cardiovascular disease, which was previously correlated with short telomere length in humans. PMID:23260664

The activities are centered around three basic networking systems: the Space Physics Analysis Network (SPAN); the Earth Science Network (ESN); and the NASA Packet Switched System (NPSS). Each system is described, linkages among systems are explained, and future plans are announced. The inclusion of several new climate nodes on SPAN or ESN are also mentioned. Presently, the Pilot Climate Data System is accessible through SPAN and will be accessible through NPSS by summer and ESN by the end of 1986. Ambitious plans for implementation are underway. The implementation of these plans will represent a major advance in the utilization and accessibility of data worldwide.

  14. 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.

    Sutong Bridge is a cable-stayed steel box girder bridge with a main span of 1 088 m. The erection of upper structure adopts geometry control method and requires no change to the unit's size and the structure's none-stress geometry. Before main span closure, the cantilever of girder reaches 540.8 m, the structure state is noticeably influenced by external circumstances, the main span closure face great difficulty. By abstracting the advantage of the pullback method abroad and the domestic temperature-cutting method, a new assistant pullback method have put forward and bring into practice actually. In this paper, the analysis key point of practice conditions, key parameter of practice, main measures of the method and the performance is introduced.

    We derive improved upper bounds on the number of crossing-free straight-edge spanning cycles (also known as Hamiltonian tours and simple polygonizations) that can be embedded over any specific set of $N$ points in the plane. More specifically, we bound the ratio between the number of spanning cycles (or perfect matchings) that can be embedded over a point set and the number of triangulations that can be embedded over it. The respective bounds are $O(1.8181^N)$ for cycles and $O(1.1067^N)$ for matchings. These imply a new upper bound of $O(54.543^N)$ on the number of crossing-free straight-edge spanning cycles that can be embedded over any specific set of $N$ points in the plane (improving upon the previous best upper bound $O(68.664^N)$). Our analysis is based on Kasteleyn's linear algebra technique.

    Prolonged life after reproduction is difficult to explain evolutionarily unless it arises as a physiological side effect of increased longevity or it benefits related individuals (i.e., increases inclusive fitness). There is little evidence that postreproductive life spans are adaptive in nonhuman animals. By using multigenerational records for two killer whale (Orcinus orca) populations in which females can live for decades after their final parturition, we show that postreproductive mothers increase the survival of offspring, particularly their older male offspring. This finding may explain why female killer whales have evolved the longest postreproductive life span of all nonhuman animals. PMID:22984064

    The purpose of this note is to establish, in a categorical manner, the universality of the Geroch-Kronheimer-Penrose causal boundary when considering the types of causal structures that may profitably be put on any sort of boundary for a spacetime. Actually, this can only be done for the future causal boundary (or the past causal boundary) separately; furthermore, only the chronology relation, not the causality relation, is considered, and the GKP topology is eschewed. The final result is that there is a unique map, with the proper causal properties, from the future causal boundary of a spacetime onto any ``reasonable" boundary which supports some sort of chronological structure and which purports to consist of a future completion of the spacetime. Furthermore, the future causal boundary construction is categorically unique in this regard.

As Newton and Plummer (2009 note “the use of the creative arts as pedagogical strategy enables individuals to better understand themselves, [and] to stimulate thinking” (p. 75.We extend that premise to examine the impact of an arts activity on scholarly thinking. Our exploratory study examines academics’ (graduate students and educators identity and role constructs (Kelly, 1955 to understand to what extent engaging in arts-based activities supports meaning-making and conceptualizing research questions. We asked participants to reflect on collages they created, how the collage process supported their research conceptualization, challenges they encountered, and their overall reflections on the process as an adjunct to written scholarly work. We show that the process of creating collages supported participants in making their tacit knowledge explicit, in reflecting at meta-cognitive levels, and in transforming their thinking, often in ways they anticipated would affect their future practice.L’intégration des arts dans la pédagogie de l’enseignement supérieur offre l’occasion de cultiver de riches idées et rend possible une réflexion d’ordre supérieur qui permet de capitaliser sur la créativité que chaque personne possède déjà et utilise (Livingston, 2010.

Dogs lose telomeric DNA ∼10-fold faster than humans, which is similar to the ratio of average life spans between these species. Breeds with shorter mean telomere lengths show an increased probability of death from cardiovascular disease, which was previously correlated with short telomere length in humans.

    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.

  13. 1-Skeletons of the Spanning Tree Problems with Additional Constraints

    Directory of Open Access Journals (Sweden)

    V. A. Bondarenko

    2015-10-01

    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.

  16. WildSpan: mining structured motifs from protein sequences

    Directory of Open Access Journals (Sweden)

    Chen Chien-Yu

    2011-03-01

    Full Text Available Abstract Background Automatic extraction of motifs from biological sequences is an important research problem in study of molecular biology. For proteins, it is desired to discover sequence motifs containing a large number of wildcard symbols, as the residues associated with functional sites are usually largely separated in sequences. Discovering such patterns is time-consuming because abundant combinations exist when long gaps (a gap consists of one or more successive wildcards are considered. Mining algorithms often employ constraints to narrow down the search space in order to increase efficiency. However, improper constraint models might degrade the sensitivity and specificity of the motifs discovered by computational methods. We previously proposed a new constraint model to handle large wildcard regions for discovering functional motifs of proteins. The patterns that satisfy the proposed constraint model are called W-patterns. A W-pattern is a structured motif that groups motif symbols into pattern blocks interleaved with large irregular gaps. Considering large gaps reflects the fact that functional residues are not always from a single region of protein sequences, and restricting motif symbols into clusters corresponds to the observation that short motifs are frequently present within protein families. To efficiently discover W-patterns for large-scale sequence annotation and function prediction, this paper first formally introduces the problem to solve and proposes an algorithm named WildSpan (sequential pattern mining across large wildcard regions that incorporates several pruning strategies to largely reduce the mining cost. Results WildSpan is shown to efficiently find W-patterns containing conserved residues that are far separated in sequences. We conducted experiments with two mining strategies, protein-based and family-based mining, to evaluate the usefulness of W-patterns and performance of WildSpan. The protein-based mining mode

    Full Text Available In this paper we state and prove some new results on the optimal boundaries. These boundaries (called Pareto boundaries too are of increasing importance in the applications to Decision Theory. First of all the Pareto boundaries are the first and most important generalization of the concept of optimum; on the other hand, if f is a real functional defined on a non empty set X and K is a part of X, the determination of the optimal boundaries of the part K with respect to some preorder of X for which f is strictly increasing permits to reduce the optimization problem (f, K, inf (or (f, K, sup to the problem (f, minP(K, inf (resp.

  19. Hamiltonian systems with boundaries

    International Nuclear Information System (INIS)

    Lately, to provide a solid ground for quantization of the open string theory with a constant B-field it has been proposed to treat the boundary conditions as hamiltonian constraints. It seems that this proposal is quite general and it should be applicable to a wide range of models defined on manifolds with boundaries. The goal of the present paper is to show how the boundary conditions can arise as constraints in a purely algebraic fashion within the Hamiltonian approach without any reference to the Lagrangian formulation of the theory. The construction of the boundary Dirac brackets is also given and some subtleties are pointed out. We consider four examples of field theories with boundaries: the topological sigma model, the open string theory with and without a constant B-field and electrodynamics with topological term. A curious result about electrodynamics on a manifold with boundaries is presented. (author)

  20. SLE boundary visits

    Jokela, Niko; Kytölä, Kalle

    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...

    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.

  8. Octave-spanning supercontinuum generation via microwave frequency multiplication

    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.

    Summarized are author's and literary data about the microgravity effects on life span and biological age of animals obtained in experiments with laboratory rats flown in biosatellites Kosmos. Exposure of rats in the spaceflight microgravity as long as 3 wk. (up to 1/50th of the life period of this species) did not reduce the life span post flight. Alterations in biological age as judged by the reproductive function, general resistance and tissue regeneration rate were minor and in a number of parameters were significantly less as compared with the shifts resulting from simulation of the physiological effects of microgravity in laboratory (for a similar period). Prospects of investigations into this problem are considered. PMID:12442585

    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.

    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...

    Telomeric DNA repeats are lost as normal somatic cells replicate. When telomeres reach a critically short length, a DNA damage signal is initiated, inducing cell senescence. Some studies have indicated that telomere length correlates with mortality, suggesting that telomere length contributes to human life span; however, other studies report no correlation, and thus the issue remains controversial. Domestic dogs show parallels in telomere biology to humans, with similar telomere length, telom...

    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.

    2009-05-27

    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

Change has been instigated and produced by the Internet and open access systems – such as disciplinary and institutional repositories and open access journals. However traditional scholarly publishing is strengthening its hold over prestigious journals thus resisting change. How then does the change come about? An attempt at answering this question led us to examine an institutional repository initiative in a University. As we ide...

  10. Altmetrics (Chapter from Beyond Bibliometrics: Harnessing Multidimensional Indicators of Scholarly Impact)

    OpenAIRE

    Priem, Jason

    2015-01-01

    This chapter discusses altmetrics (short for "alternative metrics"), an approach to uncovering previously-invisible traces of scholarly impact by observing activity in online tools and systems. I argue that citations, while useful, miss many important kinds of impacts, and that the increasing scholarly use of online tools like Mendeley, Twitter, and blogs may allow us to measure these hidden impacts. Next, I define altmetrics and discuss research on altmetric sources--both research mapping th...

    2002-01-01

    Technological developments in areas such as digitization and networking are changing scholarly communication in fundamental ways. This paper describes the most important changes and their impacts on the various actors in the information chain. Its main argument is that the responsibility for scholarly communication is shifting from functional actors such as publishers and libraries to a more integral responsibility held by the academic community itself. Publishers and libraries would then cha...

    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

    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.

  5. The eye-voice span during reading aloud

    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.

  8. Emotional Egocentricity Bias across the life-span

    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

  9. 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

    Gilmore, Claire G.; Lucey, Brian M.; Boscia, Marian W.

    2010-11-01

    The concept of a minimum spanning tree (MST) is used to study patterns of comovements for a set of twenty government bond market indices for developed North American, European, and Asian countries. We show how the MST and its related hierarchical tree evolve over time and describe the dynamic development of market linkages. Over the sample period, 1993-2008, linkages between markets have decreased somewhat. However, a subset of European Union (EU) bond markets does show increasing levels of comovements. The evolution of distinct groups within the Eurozone is also examined. The implications of our findings for portfolio diversification benefits are outlined.

    2016-09-01

    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.

  14. The span as a fundamental factor in airplane design

    Science.gov (United States)

    Lachmann, G

    1928-01-01

    Previous theoretical investigations of steady curvilinear flight did not afford a suitable criterion of "maneuverability," which is very important for judging combat, sport and stunt-flying airplanes. The idea of rolling ability, i.e., of the speed of rotation of the airplane about its X axis in rectilinear flight at constant speed and for a constant, suddenly produced deflection of the ailerons, is introduced and tested under simplified assumptions for the air-force distribution over the span. This leads to the following conclusions: the effect of the moment of inertia about the X axis is negligibly small, since the speed of rotation very quickly reaches a uniform value.

  15. Maximum Leaf Spanning Trees of Growing Sierpinski Networks Models

    CERN Document Server

    Yao, Bing; Xu, Jin

    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.

    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

    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.

    This paper deals with the problem of computing a spanning tree of a connected undirected graph G=(V,E) minimizing the sum of distance differences of all vertex pairs u,vn V which are connected by an edge {u,v}n E. We show that the decision variant of this optimization problem is NP-complete with respect to the L_p norm for arbitrary pn N. For the reduction, we use the well known NP-complete problem Vertex Cover.

  11. Performance of the multidetector NSE spectrometer SPAN at BENSC

    International Nuclear Information System (INIS)

    The NSE precession field, which is created by three pairs of coils with diameters 1, 3 and 4.8 m respectively, is the pecularity in the design of SPAN. Each pair is mounted in a Helmholtz-like fashion, with the electric currents oriented oppositely to each other, one coil above and one coil below the horizontal scattering plane. The maximum magnetic field integral is 0.06 T m typically 1/3 that of IN11. The field created by the coils with 3 m diameter is horizontal with axial symmetry. The coils with a diameter of 1 m shape the magnetic field around the sample. They produce at the sample a very homogeneous adjustable vertical field, which assures the axial symmetry of the magnetic configuration. A first series of NSE measurements are presented, which show that only little field adjustment is requires to satisfy the exact echo condition (phase) simultaneously for a large range of scattering angles and confirm the high axial symmetry of the precession field. The resolution of the spectrometer meets the expectations (∼ 8 ns maximum Fourier time at 9 A) and the results show that the new magnetic field configuration of SPAN is particularly appropriate for multidetector NSE over a wide angular range.

    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

    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.

  14. SNEV overexpression extends the life span of human endothelial cells

    International Nuclear Information System (INIS)

    In a recent screening for genes downregulated in replicatively senescent human umbilical vein endothelial cells (HUVECs), we have isolated the novel protein SNEV. Since then SNEV has proven as a multifaceted protein playing a role in pre-mRNA splicing, DNA repair, and the ubiquitin/proteosome system. Here, we report that SNEV mRNA decreases in various cell types during replicative senescence, and that it is increased in various immortalized cell lines, as well as in breast tumors, where SNEV transcript levels also correlate with the survival of breast cancer patients. Since these mRNA profiles suggested a role of SNEV in the regulation of cell proliferation, the effect of its overexpression was tested. Thereby, a significant extension of the cellular life span was observed, which was not caused by altered telomerase activity or telomere dynamics but rather by enhanced stress resistance. When SNEV overexpressing cells were treated with bleomycin or bleomycin combined with BSO, inducing DNA damage as well as reactive oxygen species, a significantly lower fraction of apoptotic cells was found in comparison to vector control cells. These data suggest that high levels of SNEV might extend the cellular life span by increasing the resistance to stress or by improving the DNA repair capacity of the cells

  15. On tight spans and tropical polytopes for directed distances

    An extension $(V,d)$ of a metric space $(S,\\mu)$ is a metric space with $S \\subseteq V$ and $d|_S = \\mu$, and is said to be tight if there is no other extension $(V,d')$ of $(S,\\mu)$ with $d' \\leq d$. Isbell and Dress independently found that every tight extension is isometrically embedded into a certain metrized polyhedral complex associated with $(S,\\mu)$, called the tight span. This paper develops an analogous theory for directed metrics, which are "not necessarily symmetric" distance functions satisfying the triangle inequality. We introduce a directed version of the tight span and show that it has such a universal embedding property for tight extensions. Also we newly introduce another natural class of extensions, called cyclically tight extensions, and show that (a fiber of) the tropical polytope, introduced by Develin and Sturmfels, has a universal embedding property for cyclically tight extensions. As an application, we prove the following directed version of tree metric theorem: directed metric $\\mu$...

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

    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

    Academic productivity, demonstrated by a record of scholarly publication, is the main criterion for academic promotion. Nevertheless, there are no data on early-career productivity milestones to guide young faculty members aspiring to attain professor status. We performed a bibliometric analysis to determine the number of scholarly papers published by current professors of orthopedic surgery within 5 years after their having acquired American Board of Orthopaedic Surgery certification (termed early scholarly output). Median early scholarly output for all professors (N = 108) was 11 publications. We found medians of 5 first-author and 2 last-author publications, and 4 publications in Clinical Orthopaedics and Related Research or Journal of Bone and Joint Surgery. Median number of papers cited at least 50 times by year 5 was 2. The median number of total citations was 29.5, and median Hirsch index (h-index) was 3. Faculty who were clinical professors published fewer papers and acquired fewer citations than faculty who were promoted but did have the clinical descriptor. Professors certified after 1995 were more productive than those certified before 1990. This descriptive study provided benchmark data on early scholarly productivity of current professors of orthopedic surgery and demonstrated this benchmark has risen in more recent years.

    Reproducibility and reusability of research results is an important concern in scientific communication and science policy. A foundational element of reproducibility and reusability is the open and persistently available presentation of research data. However, many common approaches for primary data publication in use today do not achieve sufficient long-term robustness, openness, accessibility or uniformity. Nor do they permit comprehensive exploitation by modern Web technologies. This has led to several authoritative studies recommending uniform direct citation of data archived in persistent repositories. Data are to be considered as first-class scholarly objects, and treated similarly in many ways to cited and archived scientific and scholarly literature. Here we briefly review the most current and widely agreed set of principle-based recommendations for scholarly data citation, the Joint Declaration of Data Citation Principles (JDDCP). We then present a framework for operationalizing the JDDCP; and a set of initial recommendations on identifier schemes, identifier resolution behavior, required metadata elements, and best practices for realizing programmatic machine actionability of cited data. The main target audience for the common implementation guidelines in this article consists of publishers, scholarly organizations, and persistent data repositories, including technical staff members in these organizations. But ordinary researchers can also benefit from these recommendations. The guidance provided here is intended to help achieve widespread, uniform human and machine accessibility of deposited data, in support of significantly improved verification, validation, reproducibility and re-use of scholarly/scientific data.

    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.

    The effects of periodic crosshatch roughness (k+ = 160) on a Mach 4.9 turbulent boundary layer (Reθ = 63 000) are examined using particle image velocimetry. The roughness elements generate a series of alternating shock and expansion waves, which span the entire boundary layer, causing significant (up to +50% and -30%) variations in the Reynolds shear stress field. Evidence of the hairpin vortex organization of incompressible flows is found in the comparative smooth-wall boundary layer case (Reθ = 47 000), and can be used to explain several observations regarding the rough-wall vortex organization. In general, the rough-wall boundary layer near-wall vortices no longer appear to be well-organized into streamwise-aligned packets that straddle relatively low-speed regions like their smooth-wall counterpart; instead, they lean farther away from the wall, become more spatially compact, and their populations become altered. In the lower half of the boundary layer, the net vortex swirling strength and outer-scaled Reynolds stresses increase relative to the smooth-wall case, and actually decrease in the outer half of the boundary layer, as ejection and entrainment processes are strengthened and weakened in these two regions, respectively. A spectral analysis of the data suggests a relative homogenizing of the most energetic scales near Λ = ˜ 0.5δ across the rough-wall boundary layer.
