    Background Human knowledge and innovation are recorded in two media: scholarly publication and patents. These records not only document a new scientific insight or new method developed, but they also carefully cite prior work upon which the innovation is built. Methodology We quantify the impact of information flow across fields using two large citation dataset: one spanning over a century of scholarly work in the natural sciences, social sciences and humanities, and second spanning a quarter century of United States patents. Conclusions We find that a publication's citing across disciplines is tied to its subsequent impact. In the case of patents and natural science publications, those that are cited at least once are cited slightly more when they draw on research outside of their area. In contrast, in the social sciences, citing within one's own field tends to be positively correlated with impact. PMID:19688087

    Zølner, Mette

    The paper explores how locals span boundaries between corporate and local levels. The aim is to better comprehend potentialities and challenges when MNCs draws on locals’ culture specific knowledge. The study is based on an in-depth, interpretive case study of boundary spanning by local actors...... in the period of post-acquisition when their organization is being integrated into the acquiring MNC. The paper contributes to the literature on boundary spanning in three ways: First, by illustrating that boundary spanning is performed by numerous organizational actors in a variety of positions in MNCs......, inclusively by locals in subsidiaries. Second, by showing that boundary spanning is ‘situated’ in the sense that its result depends on the kind of knowledge to be transmitted and the attitude of the receivers. A third contribution is methodological. The study illustrates that combining bottom-up grounded...

    In order to continue to be innovative in the current fast-paced and competitive environment, organizations are increasingly dependent on creative inputs developed outside their boundaries. The paper addresses the boundary spanning activities that managers undertake to a) select and mobilize...... creative talent, b) create shared identity, and c) combine and integrate knowledge in innovation projects involving external actors. We study boundary spanning activities in two creative projects in the LEGO group. One involves identifying and integrating deep, specialized knowledge, the other focuses...... on the use of external actors as a source of broad, not necessarily fully developed ideas. We find that the boundary spanning activities in these two projects differ in respect, among other things, of how the firm selects participants, formulates problems, and aligns the expectations of internal and external...

    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.

  15. Vibration analysis of multi-span beam system under arbitrary boundary and coupling conditions

    ZHENG Chaofan

    2017-08-01

    Full Text Available In order to overcome the difficulties of studying the vibration analysis model of a multi-span beam system under various boundary and coupling conditions, this paper constructs a free vibration analysis model of a multi-span beam system on the basis of the Bernoulli-Euler beam theory. The vibration characteristics of a multi-span beam system under arbitrary boundary supports and elastic coupling conditions are investigated using the current analysis model. Unlike most existing techniques, the beam displacement function is generally sought as an improved Fourier cosine series, and four sine terms are introduced to overcome all the relevant discontinuities or jumps of elastic boundary conditions. On this basis, the unknown series coefficients of the displacement function are treated as the generalized coordinates and solved using the Rayleigh-Ritz method, and the vibration problem of multi-span bean systems is converted into a standard eigenvalue problem concerning the unknown displacement expansion coefficient. By comparing the free vibration characteristics of the proposed method with those of the FEA method, the efficiency and accuracy of the present method are validated, providing a reliable and theoretical basis for multi-span beam system structure in engineering applications.

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

  20. Boundary-spanning: reflections on the practices and principles of Global Health.

    2016-01-01

    As Global Health evolves, not merely as a metaphor for international collaboration, but as a distinct field of practice, it warrants greater consideration of how it is practiced, by whom, and for what goals. We believe that, to become more relevant for the health systems and communities that are their intended beneficiaries, Global Health practices must actively span and disrupt boundaries of geography, geopolitics and constituency, some of which are rooted in imbalances of power and resources. In this process, fostering cross-country learning networks and communities of practice, and building local and national institutions with a global outlook in low and middle-income countries, are critically important. Crucially, boundary-spanning practices in Global Health require a mindset of inclusiveness, awareness of and respect for different coexisting realities.

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

    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.

    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

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

    2005-10-01

    Using work-family border theory, this article examines relationships between boundary-spanning demands and resources and work-to-family conflict and perceived stress. The analysis uses data from 2,109 respondents from the 2002 National Study of the Changing Workforce. The demands that were positively related to work-to-family conflict and perceived stress were commuting time, bringing work home, job contacts at home, and work-family multitasking. Work-family multitasking partially explained the effects of bringing work home and job contacts at home on conflict and stress. For resources, time off for family responsibilities and a supportive work-family culture showed negative associations with conflict and stress. Work-to-family conflict partially mediated relationships between several demands and resources and perceived stress. Copyright (c) 2005 APA, all rights reserved.

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

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

  9. A high frequency of XO offspring from X(Paf)Y* male mice: evidence that the Paf mutation involves an inversion spanning the X PAR boundary.

    Science.gov (United States)

    Burgoyne, P S; Evans, E P

    2000-01-01

    It has previously been reported that 19% of the daughters of males carrying the X-linked mutation patchy fur (Paf) are XO with a maternally derived X chromosome. We now report that hemizygous Paf males that also carry the variant Y chromosome Y*, show a much increased XO production ( approximately 40% of daughters). We hypothesize that the Paf mutation is associated with an inversion spanning the pseudoautosomal region (PAR) boundary, and that this leads to preferential crossing over between the resulting inverted region of PAR and an equivalent inverted PAR region within the compound Y* PAR. This would lead to the production of dicentric X and acentric Y products and consequent sex chromosome loss. This interpretation is supported by analysis of the sex chromosome complements at the second meiotic metaphase, which revealed a high incidence of dicentrics. Another curious feature of the Paf mutation is that mice that are homozygous Paf have more hair than mice that are hemizygous Paf. This can be explained if the Paf mutation is a hypomorphic mutation that escapes X inactivation because, unlike the wild type allele, it is now located within the PAR. Copyright 2001 S.

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

If we were to start from scratch today to design a quality-controlled archive and distribution system for scientific and technical information, it could take a very different form from what has evolved in the past decade from pre-existing print infrastructure. Near-term advances in automated classification systems, authoring tools, and document formats will facilitate efficient datamining and long-term archival stability, and I discuss how these could provide not only more efficient means of accessing and navigating the information, but also more cost-effective means of authentication and quality control. Finally, I illustrate the use of machine learning techniques to analyze, structure, maintain, and evolve a large online corpus of academic literature. An emerging field of research can be identified as part of an existing corpus, permitting the implementation of a more coherent community structure for its network of practitioners.

    Pepe, Alberto; Pepe, Alberto; Yeomans, Joanne

    2007-01-01

    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...

    2011-03-01

    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.

    2013-07-06

    Flight in animals is the result of aerodynamic forces generated as flight muscles drive the wings through air. Aerial performance is therefore limited by the efficiency with which momentum is imparted to the air, a property that can be measured using modern techniques. We measured the induced flow fields around six hawkmoth species flying tethered in a wind tunnel to assess span efficiency, ei, and from these measurements, determined the morphological and kinematic characters that predict efficient flight. The species were selected to represent a range in wingspan from 40 to 110 mm (2.75 times) and in mass from 0.2 to 1.5 g (7.5 times) but they were similar in their overall shape and their ecology. From high spatio-temporal resolution quantitative wake images, we extracted time-resolved downwash distributions behind the hawkmoths, calculating instantaneous values of ei throughout the wingbeat cycle as well as multi-wingbeat averages. Span efficiency correlated positively with normalized lift and negatively with advance ratio. Average span efficiencies for the moths ranged from 0.31 to 0.60 showing that the standard generic value of 0.83 used in previous studies of animal flight is not a suitable approximation of aerodynamic performance in insects.

    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.

    2015-02-01

    Scholarly publishing is an essential vehicle for actively participating in the scientific debate and for sustaining the invisible colleges of the modern research environment, which extend far beyond the borders of individual research institutions. However, its current dynamics have deeply transformed the scientific life and conditioned in new ways the economics of academic knowledge production. They have also challenged the perceived common sense view of scientific research. Analytical approach to set out a comprehensive framework on the current debate on scholarly publishing and to shed light on the peculiar organization and the working of this peculiar productive sector. The way in which scientific knowledge is produced and transmitted has been dramatically affected by the series of recent major technosocietal transformations. Although the effects are many, in particular the current overlap and interplay between two distinct and somewhat opposite stances-scientific and economic-tend to blur the overall understanding of what scholarly publishing is and produces distortion on its working which in turn affect the scientific activities. The outcome is thus a series of intended and unintended effects on the production and dissemination of scientific knowledge. The article suggests that a substantial transformation characterizes science today that seems more like a thrusting, entrepreneurial business than a contemplative, disinterested endeavor. In this essay, we provide a general overview of the pivotal role of the scholarly publishing in fostering this change and its pros and cons connected to the idiosyncratic interplay between social norms and market stances. © The Author(s) 2015.

  20. Finding and Recommending Scholarly Articles

    Science.gov (United States)

    Kurtz, Michael J.; Henneken, Edwin A.

    2014-05-01

    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. Just like everybody else involved in information discovery, scholars are confronted with information overload. 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. 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.

  1. Span of management: concept analysis.

    Science.gov (United States)

    Meyer, Raquel M

    2008-07-01

    This paper is a report of a concept analysis of span of management. Span of management is an important structural variable in evaluating the contributions of nursing managers to healthcare systems. Span of management is typically measured as a ratio. A wide variety of operational definitions have been applied and these differences have not been reconciled. A search of CINAHL, PsychINFO and Business Source Premier was completed in 2007 using the terms span of management, span of control, organizational structure, hierarchy, supervisory ratio and work group size. Key publications (1975-2007) and seminal works were included. Review methods. Morse's concept analysis approach was used to determine the pragmatic utility of the concept. A critical appraisal of the literature assessed the use of the concept across disciplines, identified inconsistencies within the concept, and uncovered assumptions and conceptual gaps. At the organizational level, span represents supervisory capability. At the level of the manager, span may reflect reporting structure, closeness of contact, or scope of the role. At the work group level, span quantifies work group size. At the employee level, span represents employee support. These measures are influenced by units of measurement and by context. A systematic understanding of span of management concepts, measures and determinants will assist nurse executives in selecting parameters to quantify the allocation of managerial resources. Researchers can incorporate these parameters in comparisons across studies and in advancing the science of nursing management.

  1. 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.

  15. MESUR metrics from scholarly usage of resources

    CERN Document Server

    CERN. Geneva; Van de Sompel, Herbert

    2007-01-01

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

    Full Text Available Evaluating the impact of a scholarly article is of great significance and has attracted great attentions. Although citation-based evaluation approaches have been widely used, these approaches face limitations e.g. in identifying anomalous citations patterns. This negligence would inevitably cause unfairness and inaccuracy to the article impact evaluation. In this study, in order to discover the anomalous citations and ensure the fairness and accuracy of research outcome evaluation, we investigate the citation relationships between articles using the following factors: collaboration times, the time span of collaboration, citing times and the time span of citing to weaken the relationship of Conflict of Interest (COI in the citation network. Meanwhile, we study a special kind of COI, namely suspected COI relationship. Based on the COI relationship, we further bring forward the COIRank algorithm, an innovative scheme for accurately assessing the impact of an article. Our method distinguishes the citation strength, and utilizes PageRank and HITS algorithms to rank scholarly articles comprehensively. The experiments are conducted on the American Physical Society (APS dataset. We find that about 80.88% articles contain contributed citations by co-authors in 26,366 articles and 75.55% articles among these articles are cited by the authors belonging to the same affiliation, indicating COI and suspected COI should not be ignored for evaluating impact of scientific papers objectively. Moreover, our experimental results demonstrate COIRank algorithm significantly outperforms the state-of-art solutions. The validity of our approach is verified by using the probability of Recommendation Intensity.

    2004-10-01

    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.

  6. Open Access Scholarly Publications as OER

    Terry Anderson

    2013-06-01

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

    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.

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.

    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.

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

  10. Imagine Something Different: How a Group Approach to Scholarly Faculty Development Can Turn Joy-Stealing Competition Into Scholarly Productivity.

    Science.gov (United States)

    Heinrich, Kathleen T

    As academic institutions across the country raise the scholarly bar for retention, promotion, and tenure, academic leaders are being asked to scholar-ready nursing faculty. With the retirement of senior scholars and too few scholar-mentors to go around, leaders often find themselves squeezed between scholarly expectations on the rise and faculty groups less than ready to meet those expectations. Today's nursing faculty present a formidable scholarly development challenge. A diverse mix of master's-prepared clinicians and recent graduates from doctor of philosophy and doctor of nursing practice programs, they come with a broad range of scholarly learning needs. These inequities not only leave many faculty feeling like scholar-impostors but also they can breed competitions that erode collegial bonds and sow the seeds of incivilities that steal scholarly joy, slow scholarly progress, and stress academic workplaces. What if leaders began imagining something different for themselves and with faculty groups? This is what can happen when leaders expand their perspective on scholarly faculty development from individual challenge to collective responsibility. More essay than research paper, this article describes how scholarly joy-stealing patterns can infiltrate faculty groups, shares thought leaders' visions for supportive scholarly communities, and offers strategies leaders can use to invite faculty groups to co-create cultures of scholarly caring.

    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?

    2018-01-01

    This article describes components of a workshop designed to orientate psychiatric trainees to the task of conducting a scholarly project. The aims are: to promote an approach that incorporates principles of adult learning to guide trainees who are undertaking research; to allow trainees to transform their ideas into more tangible research questions; and to enable supervisors to reflect on delivering similar content in scholarly project workshops. The workshop comprised: creating a safe space to explore ideas; discussing the process of posing a question or hypothesis; using group interactions to generate concepts; and considering personal values that influence the choice of research methodology to answer a question. Examples are provided from the workshop. The process enabled trainees to generate and distil ideas into more concrete questions and methods in three phases: introductory, exploratory and tangible. Adult learning principles may assist trainees to develop their ideas for a scholarly project into research questions that are relevant to clinical practice. Harnessing the creative potential of a peer collective may encourage deeper inquiry, shifts to a tangible output and a sustained interest in research.

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

  14. Developmental Origins of Health Span and Life Span: A Mini-Review.

    Preston, Joshua D; Reynolds, Leryn J; Pearson, Kevin J

    2018-01-12

    A vast body of research has demonstrated that disease susceptibility and offspring health can be influenced by perinatal factors, which include both paternal and maternal behavior and environment. Offspring disease risk has the potential to affect the health span and life span of offspring. Various maternal factors, such as environmental toxicant exposure, diet, stress, exercise, age at conception, and longevity have the potential to influence age-associated diseases such as cardiovascular disease, obesity, diabetes, and cancer risk in offspring. Paternal factors such as diet, age at conception, and longevity can potentially impact offspring health span and life span-reducing traits as well. Continued research could go a long way toward defining mechanisms of the developmental origins of life span and health span, and eventually establishing regimens to avoid negative developmental influences and to encourage positive interventions to potentially increase life span and improve health span in offspring. © 2018 S.

  16. Semi-span wind tunnel testing without conventional peniche

    Science.gov (United States)

    Skinner, S. N.; Zare-Behtash, H.

    2017-12-01

    Low-speed wind tunnel tests of a flexible wing semi-span model have been implemented in the 9× 7 ft de Havilland wind tunnel at the University of Glasgow. The main objective of this investigation is to quantify the effect of removing the traditional peniche boundary layer spacer utilised in this type of testing. Removal of the peniche results in a stand-off gap between the wind tunnel wall and the model's symmetry plane. This offers the advantage of preventing the development of a horseshoe vortex in front of the model, at the peniche/wall juncture. The formation of the horseshoe vortex is known to influence the flow structures around the entire model and thus alters the model's aerodynamic behaviours. To determine the influence of the stand-off gap, several gap heights have been tested for a range of angles of attack at Re=1.5× 10^6, based on the wing mean aerodynamic chord (MAC). Force platform data have been used to evaluate aerodynamic coefficients, and how they vary with stand-off heights. Stereoscopic Particle Imaging Velocimetry (sPIV) was used to examine the interaction between the tunnel boundary layer and model's respective stand-off gap. In addition, clay and tuft surface visualisation enhanced the understanding of how local flow structures over the length of the fuselage vary with stand-off height and angle of attack. The presented results show that a stand-off gap of four-to-five times the displacement thickness of the tunnel wall boundary layer is capable of achieving a flow field around the model fuselage that is representative of what would be expected for an equivalent full-span model in free-air—this cannot be achieved with the application of a peniche.

  2. Genetics, life span, health span, and the aging process in Caenorhabditis elegans.

    Science.gov (United States)

    Tissenbaum, Heidi A

    2012-05-01

    As a tool for measuring the aging process, life span has been invaluable in dissecting the genes that modulate longevity. Studies over the past few decades have identified several hundred genes that can modify life span in model organisms such as yeast, worms, and flies. Yet, despite this vast amount of research, we still do not fully understand how the genes that affect life span influence how an organism ages. How does modulation of the genes that affect life span contribute to the aging process? Does life-span extension result in extension of healthy aging? Here, we will focus primarily on the insulin/IGF-1 signaling pathway in Caenorhabditis elegans because members of this pathway have been shown to be associated with extended life span across phylogeny, from worms to humans. I discuss how this connects to the aging process, age-associated disease, and the potential to increase healthy aging in addition to lengthening life span.

  3. STRATEGIES FOR STANDARDIZING SPELLING OF SCHOLARLY TERMINOLOGY

    2015-01-01

    Full Text Available The paper examines the spelling of scholarly terms from two points of view: as part of the terminology system and as part of common language. It is shown that multiple objective and subjective causes determine the inevitability of spelling variation in terminology and that all types of deviation from standards concern individual vocables, not rules. Particular attention is given to cases in which specialized terms enter common usage, sometimes leading to changes in their spelling and raising the need for standardization. We analyze previous standards of terminology in general spelling dictionaries, analyze them as part of common language norms and propose possible strategies for standardizing terminology.

    2000-01-01

    The research and theorizing of Patricia Benner and colleagues have been very influential in nursing around the world. In recent years, however, her work has been challenged on both methodological and philosophical grounds, primarily from critical-hermeneutic and postmodernist perspectives. Critics have identified concerns about Benner's work, including sample limitations, decontextualized exemplars, the exclusion of social and political concerns, the problematic issues of experience and interpretation, and the unacknowledged position of the researcher. This article attempts to synthesize those critiques, and offers a comprehensive framework for constructive dialogue. Disciplinary maturity and scholarly integrity require critical reevaluation of influential texts and research programs.

    2016-01-01

    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 the time and STFT domains, and, lastly, in time-domain binaural enhancement. In these contexts, the properties of ...

  7. Linking crowding, visual span, and reading.

    Science.gov (United States)

    He, Yingchen; Legge, Gordon E

    2017-09-01

    The visual span is hypothesized to be a sensory bottleneck on reading speed with crowding thought to be the major sensory factor limiting the size of the visual span. This proposed linkage between crowding, visual span, and reading speed is challenged by the finding that training to read crowded letters reduced crowding but did not improve reading speed (Chung, 2007). Here, we examined two properties of letter-recognition training that may influence the transfer to improved reading: the spatial arrangement of training stimuli and the presence of flankers. Three groups of nine young adults were trained with different configurations of letter stimuli at 10° in the lower visual field: a flanked-local group (flanked letters localized at one position), a flanked-distributed group (flanked letters distributed across different horizontal locations), and an isolated-distributed group (isolated and distributed letters). We found that distributed training, but not the presence of flankers, appears to be necessary for the training benefit to transfer to increased reading speed. Localized training may have biased attention to one specific, small area in the visual field, thereby failing to improve reading. We conclude that the visual span represents a sensory bottleneck on reading, but there may also be an attentional bottleneck. Reducing the impact of crowding can enlarge the visual span and can potentially facilitate reading, but not when adverse attentional bias is present. Our results clarify the association between crowding, visual span, and reading.

  8. Social network sampling using spanning trees

    2016-12-01

    Due to the large scales and limitations in accessing most online social networks, it is hard or infeasible to directly access them in a reasonable amount of time for studying and analysis. Hence, network sampling has emerged as a suitable technique to study and analyze real networks. The main goal of sampling online social networks is constructing a small scale sampled network which preserves the most important properties of the original network. In this paper, we propose two sampling algorithms for sampling online social networks using spanning trees. The first proposed sampling algorithm finds several spanning trees from randomly chosen starting nodes; then the edges in these spanning trees are ranked according to the number of times that each edge has appeared in the set of found spanning trees in the given network. The sampled network is then constructed as a sub-graph of the original network which contains a fraction of nodes that are incident on highly ranked edges. In order to avoid traversing the entire network, the second sampling algorithm is proposed using partial spanning trees. The second sampling algorithm is similar to the first algorithm except that it uses partial spanning trees. Several experiments are conducted to examine the performance of the proposed sampling algorithms on well-known real networks. The obtained results in comparison with other popular sampling methods demonstrate the efficiency of the proposed sampling algorithms in terms of Kolmogorov-Smirnov distance (KSD), skew divergence distance (SDD) and normalized distance (ND).

  9. Cottrell Scholars Collaborative -- Integrating Research and Teaching

    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.

    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.

    It has been five years since some 60 political activists; many scholars and university professors among them, with alleged links to the so-called ``nationalist-religious'' group and the Freedom Movement of Iran (FMI) were arrested in March and April 2001 on a series of charges including plotting to topple the Islamic establishment in Iran. Almost all of those detained were later released on bail and stood trials before different branches of the Tehran Revolutionary Court, and court of appeals. All sessions and hearings were held behind closed doors! Final verdicts have been gradually delivered, but the judiciary refuses to enforce the sentences, drop the charges, or return the bails. The whole case has been turned into a Sword of Damocles held over the heads of all political activists who happen to be critical of the system.

    2003-11-01

    John Aitken attended the University of Edinburgh between 1763 and 1769 but did not graduate MD. He gained the membership (i.e. fellowship) of the Royal College of Surgeons of Edinburgh in 1770, and was for two sessions Senior President of the Royal Medical Society. Between 1771 and 1790 he published numerous books and pamphlets on surgery, medicine, midwifery, anatomy and physiology. As a surgeon at the Royal Infirmary, from 1779, he lectured on most subjects in the medical curriculum. John Struthers was particularly scathing of Aitken's scholarship, and this article attempts to restore Aitken's reputation as a scholar and probably one of the first of the extra-academical lecturers, who taught both anatomy and surgery in Edinburgh from 1779 until his death in 1790.

    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

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

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

  19. 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.

  10. Scholarly, digital, open: an impossible triangle?

    Directory of Open Access Journals (Sweden)

    Robin Goodfellow

    2014-01-01

    Full Text Available Contemporary approaches to the digital transformation of practice in university research and teaching sometimes assume a convergence between the digital and openness. This assumption has led to the idea of ‘digital open scholarship,’ which aims to open up scholarship to participants from outside academic scholarly communities. But scholarship, digitality and openness exist in tension with each other – we can see the individual features of each, but we cannot make sense of the whole picture. It resembles an ‘impossible triangle’. Particularly confounding is the tension between digital scholarship and open knowledge, where the former is focused on the creation by specialist communities of knowledge of a stable and enduring kind, whilst the latter is characterised by encyclopaedic knowledge and participation that is unbounded by affiliation or location. However, we need not be permanently thwarted by the apparent impossibility of this triangle. It is a stimulus to look critically at the contexts of practice in which a relationship between scholarship, digitality and openness is sought. Constructive examples of such critique can be found in the emerging research field of literacy and knowledge practice in the digital university.

The first one was copying figures from a JKMS article without citation, the second was submission of a copied manuscript of a published article to JKMS, and the third was publishing a copied JKMS article in another journal. The first and third cases violated copyrights of JKMS, but the violating journals made no action on the misconduct. The second and third cases were slightly modified copies of the source articles but similarity check by the Crosscheck could not identify the text overlap initially and after one year reported 96% overlap for the second case. The similarity of the third case was reported 3%. The Crosscheck must upgrade its system for better reliable screening of text plagiarism. The copy of the second case was committed by a corrupt Chinese editing company and also by some unethical researchers. In conclusion, plagiarism still threatens the trustworthiness of the publishing enterprises and is a cumbersome burden for editors of scholarly journals. We require a better system to increase the vigilance and to prevent the misconduct.

  12. The big picture: scholarly publishing trends 2014

    Full Text Available It is important for journal editors to keep up to date with the changes happening in the international journal environment to ensure that their own publications remain current and meet international expectations. Dramatic changes have taken place in the journals environment during the last two decades, frequently driven by technology but also by increased global participation in scholarly and scientific research and concern about the commercial influence on dissemination of knowledge. Technical solutions have attempted to address the growth in research but have sometimes added to the tsunami of information and increased the need to manage quality. To this end experiments with the traditional quality control and dissemination systems have been attempted, but news of improvements are frequently overshadowed by alarms about ethical problems. There is particular concern about some of the new publishers who are not adhering to established quality control and ethical practices. Within a potentially fragmenting system, however, there are also emerging collaborative projects helping to knit together the different elements of the publishing landscape to improve quality, linkages and access.

  13. Maintaining Scholarly Standards in Feminist Literature

    2013-03-01

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

  14. Open Access Scholarly Journal Publishing in Chinese

    2017-09-01

    Full Text Available The research literature on open access (OA publishing has mainly dealt with journals publishing in English, and studies focusing on OA journals in other languages are less common. This article addresses this gap via a case study focusing on Chinese-language OA journals. It starts with the identification of the major characteristics of this market, followed by eight semi-structured interviews to explore the key motivations behind Chinese-language OA publishing and perceived barriers. The majority of Chinese OA journals are published in Chinese, and most of them are published by universities and scholarly societies. Nearly 80% of journals were launched before the digital age and were converted to OA later. The subject distribution is highly skewed towards the science, technology, engineering and medicine (STEM fields. Publishers are motivated to convert journals to OA by an expected increase in academic impact, which would also attract more submissions. The lack of a sufficient number of high-quality submissions is perceived as the largest barrier to the successful publishing of journals. The financial instability of journals is identified as the main obstacle hindering internationalisation. The central conclusions of the study are that Chinese-language OA journals need to increase their visibility in journal indexes such as the Directory of Open Access Journals (DOAJ, and that an OA publishing platform (similar to the Latin American SciELO should be established for Chinese-language OA journals.

  15. Moses Maimonides: medieval physician and scholar.

    1999-09-13

    Moses Maimonides (1135-1204), physician and philosopher, was the greatest Jewish thinker of the Middle Ages. Faced with a life of persecution, exile, and tragedy, Maimonides overcame obstacles to become the leading physician in his era, a clinician whose skills were sought across continents. Despite long days caring for patients, Maimonides wrote extensively about both medicine and philosophy. His medical works span all topics of clinical medicine and reflect rational thinking and an understanding of the relationship between mind and body. Well known for his philosophical writings, such as The Guide for the Perplexed, Maimonides codified Jewish law and revolutionized Jewish thinking. This review of his life and achievements provides insight into the world of a remarkable 12th-century physician and may offer valuable lessons for physicians today.

    2014-05-01

    Full Text Available Introduction: The ACGME requires that residents perform scholarly activities prior to graduation, but this is difficult to complete and challenging to support. We describe a residency research program, taking advantage of environmental change aligning resident and faculty goals, to become a contributor to departmental cultural change and research development. Methods: A research program, Scholar Quest (SQ, was developed as a part of an Information Mastery program. The goal of SQ is for residents to gain understanding of scholarly activity through a mentor-directed experience in original research. This curriculum is facilitated by providing residents protected time for didactics, seed grants and statistical/staff support. We evaluated total scholarly activity and resident/faculty involvement before and after implementation (PRE-SQ; 2003-2005 and POST-SQ; 2007-2009. Results: Scholarly activity was greater POST-SQ versus PRE-SQ (123 versus 27 (p<0.05 with an incidence rate ratio (IRR=2.35. Resident and faculty involvement in scholarly activity also increased PRE-SQ to POST-SQ (22 to 98 residents; 10 to 39 faculty, p<0.05 with an IRR=2.87 and 2.69, respectively. Conclusion: Implementation of a program using department environmental change promoting a resident longitudinal research curriculum yielded increased resident and faculty scholarly involvement, as well as an increase in total scholarly activity.

  15. Signal Enhancement with Variable Span Linear Filters

    DEFF Research Database (Denmark)

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

    . 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...... the time and STFT domains, and, lastly, in time-domain binaural enhancement. In these contexts, the properties of these filters are analyzed in terms of their noise reduction capabilities and desired signal distortion, and the analyses are validated and further explored in simulations.......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...

    Sterns, H L; Dorsett, J G

    1994-01-01

    One of the challenges for individuals pursuing a career throughout their life span is how to maintain a high level of professional competence. As the composition of the workforce changes, and new technologies are developed, workers are faced with changing job demands and pressures. A major issue for the 1990s is how long a worker's skills will remain current. With rapid technological changes, workers may find it necessary to update continually their knowledge, skills, and abilities or risk becoming obsolete. Factors such as individuals' motivation and attitudes and organizational climate can contribute to choices regarding career development. Current research on the factors that contribute to career development activities is reviewed, along with the impact of multiple career transitions throughout the life span. Interventions such as retraining and outplacement, which allow individuals in later life to continue work, change jobs, and further develop their careers, are also discussed.

    2011-11-15

    One of the unsolved problems in the characterization of the optimal entanglement witnesses is the existence of optimal witnesses acting on bipartite Hilbert spaces H{sub m,n}=C{sup m} x C{sup n} such that the product vectors obeying =0 do not span H{sub m,n}. So far, the only known examples of such witnesses were found among indecomposable witnesses, one of them being the witness corresponding to the Choi map. However, it remains an open question whether decomposable witnesses exist without the property of spanning. Here we answer this question affirmatively, providing systematic examples of such witnesses. Then, we generalize some of the recently obtained results on the characterization of 2 x n optimal decomposable witnesses [R. Augusiak et al., J. Phys. A 44, 212001 (2011)] to finite-dimensional Hilbert spaces H{sub m,n} with m,n{>=}3.

    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%.

This property of visual systems is known as selective visual attention (SVA. The animal is said to have a focus of attention (FoA which it has shifted to a particular location. Visual attention normally involves an attention span at the location to which the FoA has been shifted. Here the attention span is measured in Drosophila. The fly is tethered and hence has its eyes fixed in space. It can shift its FoA internally. This shift is revealed using two simultaneous test stimuli with characteristic responses at their particular locations. In tethered flight a wild type fly keeps its FoA at a certain location for up to 4s. Flies with a mutation in the radish gene, that has been suggested to be involved in attention-like mechanisms, display a reduced attention span of only 1s.

  6. Phonological similarity effects in simple and complex span tasks.

    Science.gov (United States)

    Macnamara, Brooke N; Moore, Adam B; Conway, Andrew R A

    2011-10-01

    Three experiments were conducted to examine the effect of phonological similarity in simple and complex memory span tasks. In Experiment 1, participants performed either a simple or a complex span task, and the memoranda within lists were either phonologically similar or distinct. Phonologically similar lists consisted of words that rhymed.The simple span task was word span. There were two complex span tasks; one was the original reading span task, and the other was a variant of reading span in which all the sentences within a list were contextually related. The classic phonological similarity decrement was observed in word span. In contrast, phonological similarity facilitation was observed in both versions of reading span. This facilitation effect was further investigated in Experiment 2 using two new versions of reading span. In Experiment 2, the sentences in reading span were either short or long, and the memoranda were presented separately from, and were unrelated to, the sentences. Again, words within phonologically similar lists rhymed, and again, facilitation was observed. In Experiment 3, phonological similarity was operationalized in terms of feature overlap, rather than rhyme. The classic phonological similarity decrement was still observed in word span, but facilitation was not observed in complex span. The results suggest that phonological similarity, when operationalized using words that rhyme, serves as a list retrieval cue and that complex span tasks are more dependent on cue-driven memory retrieval mechanisms than are simple span tasks.

    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.

To conduct literature searches, respiratory therapists rely on search engines to retrieve information, but there is a dearth of literature on the comparative efficiencies of search engines for researching clinical questions in respiratory care. To compare PubMed and Google Scholar search results for clinical topics in respiratory care to that of a benchmark. We performed literature searches with PubMed and Google Scholar, on 3 clinical topics. In PubMed we used the Clinical Queries search filter. In Google Scholar we used the search filters in the Advanced Scholar Search option. We used the reference list of a related Cochrane Collaboration evidence-based systematic review as the benchmark for each of the search results. We calculated recall (sensitivity) and precision (positive predictive value) with 2 x 2 contingency tables. We compared the results with the chi-square test of independence and Fisher's exact test. PubMed and Google Scholar had similar recall for both overall search results (71% vs 69%) and full-text results (43% vs 51%). PubMed had better precision than Google Scholar for both overall search results (13% vs 0.07%, P searches with the Clinical Queries filter are more precise than with the Advanced Scholar Search in Google Scholar for respiratory care topics. PubMed appears to be more practical to conduct efficient, valid searches for informing evidence-based patient-care protocols, for guiding the care of individual patients, and for educational purposes.

  15. Semantic Web for Reliable Citation Analysis in Scholarly Publishing

    Directory of Open Access Journals (Sweden)

    2011-03-01

    Full Text Available Analysis of the impact of scholarly artifacts is constrained by current unreliable practices in cross-referencing, citation discovering, and citation indexing and analysis, which have not kept pace with the technological advances that are occurring in several areas like knowledge management and security. Because citation analysis has become the primary component in scholarly impact factor calculation, and considering the relevance of this metric within both the scholarly publishing value chain and (especially important the professional curriculum evaluation of scholarly professionals, we defend that current practices need to be revised. This paper describes a reference architecture that aims to provide openness and reliability to the citation-tracking lifecycle. The solution relies on the use of digitally signed semantic metadata in the different stages of the scholarly publishing workflow in such a manner that authors, publishers, repositories, and citation-analysis systems will have access to independent reliable evidences that are resistant to forgery, impersonation, and repudiation. As far as we know, this is the first paper to combine Semantic Web technologies and public-key cryptography to achieve reliable citation analysis in scholarly publishing

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

    Science.gov (United States)

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

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

  20. A boundary-spanning organization for transdisciplinary science on land stewardship: The Stewardship Network

    Directory of Open Access Journals (Sweden)

    A. Paige. Fischer

    2015-12-01

    Full Text Available Although people and organizations in the Great Lakes region, USA take seriously their role as stewards of natural resources, many lack capacity to fulfill that role in a meaningful way. Stepping into that gap, The Stewardship Network (TSN envisions "a world of empowered, connected communities caring for land and water, now and forever," and fulfills that vision through its mission to "connect, equip, and mobilize people and organizations to care for land and water in their communities." TSN uses a scalable model of linked local and regional capacity building, science communication, civic engagement, and on-the-ground stewardship activities to achieve these goals. The model engages local and regional groups in an ongoing process of learning around conservation and restoration that improves social and ecological knowledge. I share the story of TSN to demonstrate how transdisciplinary science can take hold locally and expand regionally to bring people from diverse disciplines and functional roles together to solve common problems. I demonstrate how researchers and practitioners can collaborate to create enduring mechanisms of social and ecological change.

    2014-12-01

    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?

    Feinstein, Robert E; Yager, Joel

    2013-07-01

    Guided by ACGME's requirements, psychiatric residency training in psychotherapy currently focuses on teaching school-specific forms of psychotherapy (i.e., cognitive-behavioral, supportive, and psychodynamic psychotherapy). On the basis of a literature review of common factors affecting psychotherapy outcomes and experience with empirically supported and traditional psychotherapies, the authors aimed to develop an advanced contemporary and pragmatic approach to psychotherapy training for eight residents (two per PGY year) enrolled in a specialized Psychotherapy Scholars' Track within an adult general-residency program. The authors developed core principles and clinical practices, and drafted year-by-year educational goals and objectives to teach the psychotherapy scholars. Based on experiential learning principles, we also developed an individualized form of psychotherapy training, which we call "The Apprenticeship Model." The Psychotherapy Scholars' Track, and "Apprenticeship Model" of training are now in their third year. To date, authors report that scholars are highly satisfied with the structure and curriculum in the track. Trainees appreciate the protected time for self-directed study, mentored scholarship, and psychotherapy rotations. Patients and the Psychotherapy Scholars experience the "Apprenticeship Model" of psychotherapy training as authentic and compatible with their needs and resources. The Psychotherapy Scholars' Track developed and piloted in our general psychiatry residency is based on common factors, empirically-supported treatments, and use of experiential learning principles. Whether the Psychotherapy Scholars' Track and "Apprenticeship Model" will ultimately increase residents' psychotherapy skills and positively affect their ability to sustain postgraduate psychotherapy practice in varied settings requires long-term evaluation. The developers welcome empirical testing of the comparative effectiveness of this psychotherapy teaching approach

    The purpose of our study was to evaluate the educational value of an annual Senior Scholars Forum (SSF) of graduating Emergency Medicine resident participants and attendees. This study was conducted at an urban academic medical center with a PGY1-4 year residency program. After completion of the 2nd annual SSF, a web-based survey instrument was sent to all resident and faculty attendees. The instrument was a 3-part tool adapted from previous studies on postgraduate scholarship. Data were analyzed using descriptive statistics. Forty-two of the 44 (95%) attendees completed the survey, including 100% of the PGY4 resident presenters. Prior to the SSF, 52% of respondents did not have a full understanding of senior scholarly activities. After the SSF, 67% reported an improved understanding and 88% had a better understanding of the scope of potential scholarly projects. Sixty-four percent reported the SSF introduced them to departmental resources available for completion of their own scholarly projects, and 69% would have liked to have heard the lessons communicated earlier in residency. Most (79%) agreed the SSF demonstrated the value of communal scholarly activities. Most senior residents (67%) felt most of the department would not know about their scholarship if they had not participated in the SSF. Our innovative SSF enhanced the scholarship process by allowing graduating senior residents an opportunity to share their scholarly productivity with a larger audience, provided attendees critical insights into the process of scholarship, and encouraged communal learning. Because the Accreditation Council for Graduate Medical Education and Residency Review Committee require all residents to participate in scholarly activity, other training programs may benefit from a similar educational experience.

    One reason that it is so difficult to build electronic systems for collecting and sharing health information is that their design and implementation requires clear goals and a great deal of collaboration among people from diverse social and occupational worlds. This paper uses empirical examples from two Australian health informatics projects to illustrate the importance of boundary objects and boundary spanning activities in facilitating the high degree of collaboration required for the design and implementation of workable systems.

    Dear, Peter; Jasanoff, Sheila

    2010-12-01

    The boundaries between the history of science and science and technology studies (STS) can be misleadingly drawn, to the detriment of both fields. This essay stresses their commonalities and potential for valuable synergy. The evolution of the two fields has been characterized by lively interchange and boundary crossing, with leading scholars functioning easily on both sides of the past/present divide. Disciplines, it is argued, are best regarded as training grounds for asking particular kinds of questions, using particular clusters of methods. Viewed in this way, history of science and STS are notable for their shared approaches to disciplining. The essay concludes with a concrete example--regulatory science--showing how a topic such as this can be productively studied with methods that contradict any alleged disciplinary divide between historical and contemporary studies of science.

  12. The Community Research Scholars Initiative: A Mid‐Project Assessment

    Science.gov (United States)

    Pike, Earl; Sehgal, Ashwini R.; Fischer, Robert L.; Collins, Cyleste

    2015-01-01

    Abstract 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

    Understanding scientific collaboration networks can assist research centres to develop strategies to maximize productivity, and help diagnose the causes of low system productivity. The purpose of this study was to use social network analysis to better understand how research collaboration within a productive department impacts scholarly productivity individually and departmentally. Over a 13-year period, departmental faculty completed an annual survey describing their research collaborations and scholarly productivity. Data were analyzed using social network analysis. Quadratic assignment procedure regression assessed the predictive value that an individual's measures of centrality within the network and effective size of their own network (egonet) had each year in predicting each scholarly outcome. Simulation Investigation for Empirical Network Analysis software assessed the co-evolution of the collaborative network and scholarship. While no consistent patterns for individual's presentations were seen, individual's publications were associated with betweenness and eigenvector centrality, and effective egonet size. Grant submissions were associated with degree and eigenvector centrality, as well as effective egonet size. Departmentally, network dynamics depended upon the scholarship of those around you, but none of the forms of scholarship depended upon network characteristics. Of the three forms of scholarship, network dynamics depended primarily on publications in others. Although individual scholarship was dependent upon individual centrality and effective egonet size, research collaboration within the department depended upon reciprocity, transitivity and scholarly productivity of its constituent investigators. Scholarly dynamics, at a departmental level, did not depend upon network characteristics. © 2012 Blackwell Publishing Ltd.

  14. Uncertainty in action: observing information seeking within the creative processes of scholarly research

    2006-01-01

    Full Text Available Introduction. This paper discusses the role uncertainty plays in judgments of the meaning and significance of ideas and texts encountered by scholars in the context of their ongoing research activities. Method. Two experienced scholars were observed as part of a two-year ethnographic study of their ongoing research practices. Layered transcriptions of document-by-document discussions, conversations and interviews with informants were analysed for evidence of uncertainty in informants' processes of discovery, evaluation, use and generation of information. Analysis. Three themes are discussed illustrating the dynamic interplay between positive and negative forms of uncertainty: partial relevance, boundaries of understanding and uncertainty tolerance. Results. The uncertainty experienced by informants takes many forms deeply embedded in the interwoven layers of information seeking and use. Positive forms of uncertainty were often, but not exclusively, associated with the informants' explorations within the wider research tasks in which they were engaged. Conclusion. The intricacy of the relationship between what we might consider desirable as opposed to undesirable uncertainty is not easily unravelled. From the searcher's perspective, the interplay between positive and negative forms may be one way of explaining their ability to tolerate challenging encounters within their information and research processes.

  15. How do High Energy Physics scholars search their information?

    2008-01-01

    Grey literature has always been the main conduit of scholarly communication for High-Energy Physics (HEP)researchers. An efficient way of searching and accessing this information is a central part of their research workflow. In 2007, a survey was conducted to understand which information resources HEP scholars use to find the information they need. The results of this survey are presented. Over 2000 answers, representing about one-tenth of the active HEP community, were collected and show that community-driven resources largely dominate the landscape, with commercial services serving only a small proportion of the users. In addition, HEP scholars appear to use different tools for different information needs, which are clearly prioritized. Finally, the results of the survey shed light on the future information needs of HEP scientists over the next five years.

    Scholars in nursing science have long espoused the concept of health equity without specifically using the term or dialoguing about the social determinants of health and social justice. In this paper, we describe the development, implementation, and evaluation of a doctoral and post- doctoral seminar collective entitled Health Equity: Conceptual, Linguistic, Methodological and Ethical Issues. The course enabled scholars-in-training to consider the construct and its nuances and frame a personal philosophy of health equity. We offer an example of how a group of emerging scholars can engage in the important, but difficult discourse related to health equity. The collective provided a forum for debate, intellectual growth, and increased insight for students and faculty. We posit that the lessons learned by all participants have the potential to enrich doctoral and post-doctoral scientific training in nursing science and may serve as a model for other research training programs in the health sciences.

  17. Scholarly Reputation Building: How does ResearchGate Fare?

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available Employing a newly developed conceptual framework of the tasks and activities that comprise today’s digital scholarly undertaking and their potentially reputation building, maintaining and enhancing components, the efforts of ResearchGate in supporting scholars’ reputation building endeavours were put under the microscope. Not unexpectedly, RG performs well in regard to basic research activities. Clearly, too, with ten metrics at its disposal, RG is in a league of its own when it comes to monitoring individual research reputation. Where RG falls down is regarding scholarly activities that do not concern pure research and so especially teaching. Its claim to have created a new way of measuring reputation is only partially true because if it wants to do so genuinely then it needs to extend the range of scholarly activities covered. RG also falls short in informing members as to the nature and changes to its service and of embracing new actors, such as citizen scientists and amateur experts.

  18. Online Scholarly Conversations in General Education Astronomy Courses

    Science.gov (United States)

    Cai, Qijie; Wong, Ka-Wah

    2018-01-01

    In general education astronomy courses, many students are struggling with understanding the foundational concepts and theories in astronomy. One of the possible reasons is that, due the large class size, many of the courses are taught using a lecture mode, where human interactions and active learning are limited (Freeman et al., 2014). To address this challenge, we have applied the knowledge building framework (Scardamalia & Bereiter, 2006) to design an online collaborative learning component, called Scholarly Conversations, to be integrated into a general education astronomy course at a public, comprehensive university.During Scholarly Conversations, students are treated as scholars to advance knowledge frontiers (Scardamalia & Bereiter, 2006). The whole process involves the creation of new ideas and requires discourse and collective work for the advancement and creation of artifacts, such as theories and models (van Aalst, 2009). Based on the knowledge building principles (Scardamalia, 2002; Zhang, Scardamalia, Reeve, & Messina, 2009), several features have been built into Scholarly Conversations so that students are guided to deepen understanding of the astronomy concepts through three phases: knowledge sharing, knowledge construction and knowledge building, and reflections on learning growth (van Aalst, 2009; Cai, 2017). The online Scholarly Conversation is an extension of the lecture component of the general education astronomy course. It promotes student interactions and collaborative learning, and provides scaffolds for students to construct meanings of the essential concepts in astronomy through social learning and online technology. In this presentation, we will explain the specific design principles of the online Scholarly Conversation, and share the artifacts created to facilitate the online conversations in an general education astronomy course.Note: This project has been supported by the College of Education Research Grant Program at Minnesota State

    Free spanning of the multi-span pipeline is an important subject for design of pipeline in uneven seabed. The seabed intervention costs are largely influenced by pipeline spanning design, which includes assessment of trawl pullover response, vortex-induced vibrations and wave-induced fatigue. The objective of this paper is to develop a rational design methodology for the determination of the free span lengths based on the multi-span pipeline in-line fatigue assessment. Following the summary of the procedure, a detailed mathematical model for the free span movement and its analytical closed form solution are developed. The fatigue damage models are detailed both in time domain and frequency domain approaches. A numerical example is presented to illustrate the technical models. (author)

  7. A global climatology of boundary layer ventilation

    McNamara, David; Plant, Robert; Belcher, Stephen

    2013-04-01

    The general circulation pattern of the Earth's atmosphere is well known, however there has been relatively little effort to quantify the climatological effects of the buffer zone known as the atmospheric boundary layer. Turbulent motions in the atmospheric boundary layer act to mix the layer along with its constituent pollutants, below a temperature inversion which separates it from the free troposphere. Exchanges between the boundary layer and free troposphere can occur through the mechanisms of convection, isentropic uplift, and coastal and orographic venting. In particular the rate at which pollutants are removed from the atmosphere can be different depending on whether or not they are resident within the boundary layer or the free troposphere. Thus the limiting factor on the concentrations of, for example, certain eg NOx, pollutants in the free troposphere will be the rate at which they are vented from the boundary layer. A global climatology (spanning 10 years between 1995 and 2005) of boundary layer venting is presented here using the ERA-interim dataset which has a grid scale resolution of 0.7 degrees x 0.7 degrees. The boundary layer height is first calculated using a bulk Richardson number method and then an associated vertical velocity is found by linearly interpolating between the two model levels either side of the boundary layer height. This value along with the change in height of the boundary layer over a 3 hour period is used to give an estimate of the rate of venting. The climatology of this rate allows us to describe and quantify the areas of the globe that are responsible for boundary layer entrainment and boundary layer venting, which could be used as a basis for further comparisons with other suitable datasets. We will also present results for the climatology of the boundary layer height itself. [possibly? That could be attractive for a BL audience anyway] Furthermore we will present and discuss results from a method designed to isolate the

  11. 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.

    Tetsworth, Kevin; Fraser, Dave; Glatt, Vaida; Hohmann, Erik

    2017-01-01

    The purpose of this study was to survey the growth of Google Scholar public profiles in orthopedics over a 12-month period and to investigate global patterns. Data was prospectively acquired from June 2013 to June 2014. Google Scholar queries specific to orthopedic surgery were performed at 90-day intervals. Demographic aspects of each user were also compiled, including gender, current location, and primary interests. To determine differences between the growth of Google Scholar public profile registrations and citation counts, as well as differences in growth in different regions, repeated measures of analysis of variance (RMANOVA) were used. RMANOVA revealed statistically significant differences ( p = 0.0001) for regional growth. The largest growth was observed in the United Kingdom ( p = 0.009, 289%), followed by the Asia-Pacific region ( p = 0.004, 177%) and "Other" ( p = 0.006, 172%). The mean growth per 90-day interval is 19.9% ( p = 0.003) and the mean 12-month growth is 107% ( p = 0.05). Statistically significant differences between gender (male vs. female) and basic and clinical sciences ( χ 2 = 22.4, p = 0.0001) were observed. This study suggests an exponential growth in the number of authors in the field of orthopedic surgery creating a Google Scholar public profile, and at the current rate participation doubles every 10.6 months.

    Deal, Eli N; Stranges, Paul M; Maxwell, Whitney D; Bacci, Jennifer; Ashjian, Emily J; DeRemer, David L; Kane-Gill, Sandra L; Norgard, Nicholas B; Dombrowski, Lauren; Parker, Robert B

    2016-12-01

    Regardless of practice setting, it is imperative that pharmacists be able to either participate in generating new knowledge or use the ever-expanding body of literature to guide patient care. However, competing priorities in Pharm.D. curricula and residency training programs have resulted in limited emphasis on acquiring research and scholarly skills. Factors likely contributing to this reduced focus include the lack of curricular and postgraduate training standards emphasizing the development of research skills, time to commit to scholarly activity, and accessibility to experienced mentors. Strategies for increasing scholarly activity for pharmacy students and residents should therefore continue to be a focus of professional degree and residency training programs. Several resources are available for academic planners, program directors, and institutions to augment scholarly experience for pharmacy trainees and clinicians. This commentary highlights the importance of providing research opportunities for students and residents, describes the potential barriers to these activities, and provides recommendations on how to increase the instruction and mentoring of trainees to generate and use research. © 2016 Pharmacotherapy Publications, Inc.

  13. The effects of dopamine on digit span in Parkinson's disease.

    Science.gov (United States)

    Warden, Clara; Hwang, Jaclyn; Marshall, Anisa; Fenesy, Michelle; Poston, Kathleen L

    2016-01-01

    Parkinson's disease patients are at an elevated risk of developing cognitive impairment. Although cognitive impairment is one of the strongest predictors of quality of life, dopaminergic anti-parkinsonian medications are designed to target motor symptoms. However, there is substantial evidence that dopamine also impacts cognition, in particular working memory. It is therefore critical for movement disorders physicians to understand the potential dopaminergic effects on working memory when prescribing these medications. Verbal digit span tasks offer a potentially straightforward and quick assessment of baseline working memory. Moreover, Digit Span Backward was recently validated as a screening tool for mild cognitive impairment in Parkinson's disease when participants were medicated. Research indicates that the interaction between dopamine and working memory follows an Inverted-U shaped curve, but the effect of dopamine on Digit Span has not been well studied. Our study seeks to: (1) determine the validity of verbal Digit Spans for detecting cognitive impairment in Parkinson's disease patients both ON and OFF medications; and (2) ascertain the effects of dopaminergic medications on verbal Digit Span. We recruited 64 Parkinson's disease patients and 22 age-and education-matched controls. Parkinson's patients completed Digit Span Backward and Digit Span Forward ON and OFF medications, while healthy controls completed them once. All participants were categorized by cognitive diagnosis using level-II consensus criteria. Digit Span Backward successfully identified mild cognitive impairment in Parkinson's disease, both ON and OFF medications. Combining patients with and without cognitive impairment, we found that dopamine significantly improved performance on Digit Span Backward, but not Forward. In a secondary analysis, we found this dopaminergic improvement was restricted to the Low baseline working memory group; the High baseline working memory group was unaffected

  3. Stable Boundary Layer Issues

    OpenAIRE

    Steeneveld, G.J.

    2012-01-01

    Understanding and prediction of the stable atmospheric boundary layer is a challenging task. Many physical processes are relevant in the stable boundary layer, i.e. turbulence, radiation, land surface coupling, orographic turbulent and gravity wave drag, and land surface heterogeneity. The development of robust stable boundary layer parameterizations for use in NWP and climate models is hampered by the multiplicity of processes and their unknown interactions. As a result, these models suffer ...

  4. Beyond bibliometrics harnessing multidimensional indicators of scholarly impact

    CERN Document Server

    Sugimoto, Cassidy R

    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...

    Chichester, Tiffany; Hagglund, Karen; Edhayan, Elango

    2013-03-01

    The ability to critically appraise scholarly journals is an essential skill for surgical residents in their journey to being lifelong learners. Methods to teach evaluation of scholarly articles are scant in the educational literature. Residents completed a pre-test on evaluation of surgical literature. Two lectures on methodology and statistics followed. A board-certified surgeon and residents evaluated 7 articles using a scoring form. A post-test followed. Four additional sessions on evaluating surgical articles were held without the rating form. Residents completed a second post-test. Residents showed improved knowledge and skills on evaluating surgical literature on the first and second post-tests when compared with the pretest ( P constructivist Educational theory. There was a significant improvement in knowledge and the skills of literature evaluation, which persisted after the educational aid was removed. Copyright © 2013 Elsevier Inc. All rights reserved.

  6. National and international scientific elites: an analysis of Chinese scholars

    Energy Technology Data Exchange (ETDEWEB)

    Shu, F.; Larivière, V.; Julien, C.A.

    2016-07-01

    The purpose of this study is to compare the WoS with a national Chinese bibliometric database at the level of individual authors and measure the extent of the overlap of the group of authors that are the most active in the two data sources. The results indicate that Chinese scholars do not have homogeneous publication patterns: some very productive scholars mostly publish in international (WoS) journals while others prefer to diffuse their research results in national Chinese journals. Disciplines that are most international in scope exhibit a much higher level of overlap than those of the social sciences and humanities. These results suggest that the WoS does not accurately represent Chinese research activities, especially in social science and humanities, but that it also has a relative overlap with the Chinese national scientific literature in the natural and medical sciences.

  7. The new scholarly universe: are we there yet?

    Directory of Open Access Journals (Sweden)

    Michael Taylor

    2012-03-01

    Full Text Available Despite long-standing threats of disruption to scholarly publishing, the community has remained remarkably unchanged over the last two decades. However, underlying this apparent inertia, there is an alternative approach that may emerge over the next few years as known problems move into the foreground, and a number of key social and technical issues are resolved. Furthermore, the industry of science and scientific communication are not isolated from the current economic epoch: collaboration and cost-effectiveness are strong drivers for change. The technological components of this new scholarly universe – natural language processing, semantic technologies such as taxonomies, ontologies and linking – will come together with collaborative innovations inspired by Web 2.0 social media. The final components in recreating a new publishing model are identity and reward, and these are being resolved by the forthcoming Open Research and Contributor ID (ORCID project and the altmetrics movement respectively.

  8. Towards an Open Infrastructure for Relating Scholarly Assets.

    Science.gov (United States)

    Munro, Christopher; Couch, Philip; Johnson, Jon; Ainsworth, John; Buchan, Iain

    2017-01-01

    Discovery of useful relationships between scholarly assets on the web is challenging, both in terms generating the right metadata around the assets, and in connecting all relevant digital entities in chain of provenance accessible to the whole community. This paper reports the development of a framework and tools enabling scholarly asset relationships to be expressed in a standard and open way, illustrated with use-cases of discovering new knowledge across cohort studies. The framework uses Research Objects for aggregation, distributed databases for storage, and distributed ledgers for provenance. Our proposal avoids management by a single central platform or organization, instead leveraging the use of existing resources and platforms across natural partnerships. Our proposed infrastructure will support a wide range of users from system administrators to researchers.

    Science.gov (United States)

    Busch, N A; Silver, I A

    1987-01-01

    The probability that an oxygen particle will reach a time dependent boundary is required in oxygen transport studies involving solution methods based on probability considerations. A Volterra integral equation is presented, the solution of which gives directly the boundary crossing probability density function. The boundary crossing probability is the probability that the oxygen particle will reach a boundary within a specified time interval. When the motion of the oxygen particle may be described as strongly Markovian, then the Volterra integral equation can be rewritten as a generalized Abel equation, the solution of which has been widely studied.

    Laura Ng

    2017-03-01

    Full Text Available Scholarly personal narrative (SPN extends the available methodologies by which researchers conduct the Scholarship of Teaching and Learning (SoTL. In this article, the authors define SPN, which interprets personal experience through scholarly frameworks, leveraging the power of reflective practice to understand the interpersonal dynamics of both the classroom and wider academic communities. SPN fosters disciplinary understandings of SoTL and bridges discourse barriers in order to illuminate the complex environments of teaching and learning. The article examines how widely-accepted definitions of scholarship apply to SPN and provides a scholarly approach for researchers to analyze personal experience as a pool of data, employ a range of analytical techniques, and identify significant results. Through an analysis of two articles, the authors discuss the usefulness of SPN both as a major and minor critical lens. The inclusion of SPN may enrich SoTL pluralism and contribute to the knowledge of the complex contexts and influences that shape instructors, learning environments, and student experiences.

    Svider, Peter F; Husain, Qasim; Mauro, Kevin M; Folbe, Adam J; Baredes, Soly; Eloy, Jean Anderson

    2014-02-01

    Our objectives were to evaluate collaboration with medical students and other nondoctoral authors, and assess whether mentoring such students influences the academic productivity of senior authors. Six issues of the Laryngoscope and International Forum of Allergy & Rhinology (IFAR) were examined for the corresponding author of each manuscript, and whether any students were involved in authorship. The h-index of all corresponding authors was calculated using the Scopus database to compare the scholarly impact of authors collaborating with students and those collaborating exclusively with other physicians or doctoral-level researchers. Of 261 Laryngoscope manuscripts, 71.6% had exclusively physician or doctoral-level authors, 9.2% had "students" (nondoctoral-level authors) as first authors, and another 19.2% involved "student" authors. Corresponding values for IFAR manuscripts were 57.1%, 6.3%, and 36.5%. Corresponding authors who collaborated with students had higher scholarly impact, as measured by the h-index, than those collaborating exclusively with physicians and doctoral-level scientists in both journals. Collaboration with individuals who do not have doctoral-level degrees, presumably medical students, has a strong association with scholarly impact among researchers publishing in the Laryngoscope and IFAR. Research mentorship of medical students interested in otolaryngology may allow a physician-scientist to evaluate the students' effectiveness and functioning in a team setting, a critical component of success in residency training, and may have beneficial effects on research productivity for the senior author. © 2013 ARS-AAOA, LLC.

  20. MESUR: USAGE-BASED METRICS OF SCHOLARLY IMPACT

    Energy Technology Data Exchange (ETDEWEB)

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

    2007-01-30

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

  1. Reference rot in scholarly statement: threat and remedy

    Directory of Open Access Journals (Sweden)

    Peter Burnhill

    2015-07-01

    Full Text Available As the scholarly communication system evolves to become natively web based, citations now commonly include hyperlinks to content that is issued on the web. The content at the end of those hyperlinks is subject to what has been termed ‘reference rot’: a link may break or the content at the end of the link may no longer represent what was first noted as significant. Reference rot threatens both the usability of what is published and the long-term integrity of the scholarly record. The aim of the Hiberlink project has been to focus on this problem and then to compile and analyse a large corpus of full-text publications in order to quantify the extent of reference rot. The results are now out, and the task has shifted to alerting publishers and libraries on what to do in order to ensure that published web-based references do not rot over time. This has implications for the integrity of the scholarly record and for authors of that record. Fortunately, the Hiberlink project has progressed further than originally envisaged and has recommended remedies aimed at alleviating reference rot.

  2. A 5-year experience with an elective scholarly concentrations program

    George, Paul; Green, Emily P.; Park, Yoon S.; Gruppuso, Philip A.

    2015-01-01

    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 scholarly program with

    Dasaro, E. A.; Sanford, T. B.; Terrill, E.; Price, J.

    2006-12-01

    The upper ocean beneath the peak winds of Hurricane Frances (57 m/s) was measured using several varieties of air-deployed floats as part of CBLAST. A multilayer structure was observed as the boundary layer deepened from 20m to 120m in about 12 hours. Bubbles generated by breaking waves create a 10m thick surface layer with a density anomaly, due to the bubbles, of about 1 kg/m3. This acts to lubricate the near surface layer. A turbulent boundary layer extends beneath this to about 40 m depth. This is characterized by large turbulent eddies spanning the boundary layer. A stratified boundary layer grows beneath this reaching 120m depth. This is characterized by a gradient Richardson number of 1/4, which is maintained by strong inertial currents generated by the hurricane, and smaller turbulent eddies driven by the shear instead of the wind and waves. There is little evidence of mixing beneath this layer. Heat budgets reveal the boundary layer to be nearly one dimensional through much of the deepening, with horizontal and vertical heat advection becoming important only after the storm had passed. Turbulent kinetic energy measurements support the idea of reduced surface drag at high wind speeds. The PWP model correctly predicts the degree of mixed layer deepening if the surface drag is reduced at high wind speed. Overall, the greatest uncertainty in understanding the ocean boundary layer at these extreme wind speeds is a characterization of the near- surface processes which govern the air-sea fluxes and surface wave properties.

    This article had four goals. First, the authors identified a set of general challenges and questions that a life-span theory of development should address. Second, they presented a comprehensive account of their Motivational Theory of Life-Span Development. They integrated the model of optimization in primary and secondary control and the action-phase model of developmental regulation with their original life-span theory of control to present a comprehensive theory of development. Third, they reviewed the relevant empirical literature testing key propositions of the Motivational Theory of Life-Span Development. Finally, because the conceptual reach of their theory goes far beyond the current empirical base, they pointed out areas that deserve further and more focused empirical inquiry. PMID:20063963

Multiple stimulus factors are thought to contribute to the occurrence of BE, including object recognition, conceptual knowledge of scenes, and amodal perception at the view boundaries (Intraub, Wiley Interdisciplinary Reviews: Cognitive Science 3:117-127, 2012). In the present study, we used abstract scenes instead of images of the real world, in order to remove expectations based on semantic associations with objects and the schematic context of the view. Close-angle and wide-angle scenes were created using irregular geometric shapes rated by independent observers as lacking any easily recognizable structure. The abstract objects were tested on either a random-dot or a blank background in order to assess the influence of implied continuation of the image beyond its boundaries. The random-dot background conditions had background occlusion cues either present or absent at the image border, in order to test their influence on BE in the absence of high-level information about the scenes. The results indicate that high-level information about objects and schematic context is unnecessary for BE to occur, and that occlusion information at the image boundary also has little influence on BE. Contrary to previous studies, we also found clear BE for all conditions, despite using scenes depicting undetailed objects on a blank white background. The results highlighted the ubiquitous nature of BE and the adaptability of scene perception processes.

  9. A Study of Innovative Features in Scholarly Open Access Journals

    Science.gov (United States)

    2011-01-01

    Background The emergence of the Internet has triggered tremendous changes in the publication of scientific peer-reviewed journals. Today, journals are usually available in parallel electronic versions, but the way the peer-review process works, the look of articles and journals, and the rigid and slow publication schedules have remained largely unchanged, at least for the vast majority of subscription-based journals. Those publishing firms and scholarly publishers who have chosen the more radical option of open access (OA), in which the content of journals is freely accessible to anybody with Internet connectivity, have had a much bigger degree of freedom to experiment with innovations. Objective The objective was to study how open access journals have experimented with innovations concerning ways of organizing the peer review, the format of journals and articles, new interactive and media formats, and novel publishing revenue models. Methods The features of 24 open access journals were studied. The journals were chosen in a nonrandom manner from the approximately 7000 existing OA journals based on available information about interesting journals and include both representative cases and highly innovative outlier cases. Results Most early OA journals in the 1990s were founded by individual scholars and used a business model based on voluntary work close in spirit to open-source development of software. In the next wave, many long-established journals, in particular society journals and journals from regions such as Latin America, made their articles OA when they started publishing parallel electronic versions. From about 2002 on, newly founded professional OA publishing firms using article-processing charges to fund their operations have emerged. Over the years, there have been several experiments with new forms of peer review, media enhancements, and the inclusion of structured data sets with articles. In recent years, the growth of OA publishing has also been

    Full Text Available The article describes the evolution of scholarly communication through scholarly journals. It gives a short overview of the historical development, starting from the first journals in the 17th century to problems in the 20th century (such as increase in the number of journals, problems of accessibility, visibility, and journal access crisis. The open access (OA movement is described. It arose from the “old tradition” facing new technologies and was supposed to be the solution to the journal crisis that culminated in 1990s. The idea, defined in the Budapest Open Access Initiative, was to assure free and unrestricted online availability of peer-reviewed journal literature. The beginnings of formal scholarly communication, back in 1665, had similar ideas of making research results available to the widest possible public. The idea was excellent – removing access barriers would increase visibility, impact and quality of research. Research has shown that OA articles have better impact and visibility (Lawrence, Brody, Harnad, Haajem, etc.. However, publishing scientific information has its costs. New models have been developed, some of them causing new restrictions and barriers. The most popular model is the author-pays model (article processing charges, APC – if authors can afford to pay the processing charges, their work is published and thus more visible and more citable. However, if they cannot, a new problem arises – some research results, although valuable, are not published in open access and therefore they have lower visibility and impact. Another problem is the phenomenon of the so-called predatory publishers. Those publishers use the APC model but neglect quality control mechanisms in order to make profit. Their criteria for publishing are not positive peer-reviews but payments made by authors or their institutions. Predatory publishers’ practices are not only unethical, but also illegal, and they are a great threat to the

  9. The New Landscape of Ethics and Integrity in Scholarly Publishing

    Science.gov (United States)

    Hanson, B.

    2016-12-01

    Scholarly peer-reviewed publications serve five major functions: They (i) have served as the primary, useful archive of scientific progress for hundreds of years; (ii) have been one principal way that scientists, and more recently departments and institutions, are evaluated; (iii) trigger and are the source of much communication about science to the public; (iv) have been primary revenue sources for scientific societies and companies; and (v) more recently play a critical and codified role in legal and regulatory decisions and advice to governments. Recent dynamics in science as well as in society, including the growth of online communication and new revenue sources, are influencing and altering particularly the first four core functions greatly. The changes in turn are posing important new challenges to the ethics and integrity of scholarly publishing and thus science in ways that are not widely or fully appreciated. For example, the expansion of electronic publishing has raised a number of new challenges for publishers with respect to their responsibility for curating scientific knowledge and even preserving the basic integrity of a manuscript. Many challenges are realted to new or expanded financial conflicts of interest related to the use of metrics such as the Journal Impact Factor, the expansion of alternate business models such as open access and advertising, and the fact that publishers are increasingly involved in framing communication around papers they are publishing. Solutions pose new responsibilities for scientists, publishers, and scientific societies, especially around transparency in their operations.

  10. An Overview on Evaluating and Predicting Scholarly Article Impact

    Directory of Open Access Journals (Sweden)

    Xiaomei Bai

    2017-06-01

    Full Text Available Scholarly article impact reflects the significance of academic output recognised by academic peers, and it often plays a crucial role in assessing the scientific achievements of researchers, teams, institutions and countries. It is also used for addressing various needs in the academic and scientific arena, such as recruitment decisions, promotions, and funding allocations. This article provides a comprehensive review of recent progresses related to article impact assessment and prediction. The review starts by sharing some insight into the article impact research and outlines current research status. Some core methods and recent progress are presented to outline how article impact metrics and prediction have evolved to consider integrating multiple networks. Key techniques, including statistical analysis, machine learning, data mining and network science, are discussed. In particular, we highlight important applications of each technique in article impact research. Subsequently, we discuss the open issues and challenges of article impact research. At the same time, this review points out some important research directions, including article impact evaluation by considering Conflict of Interest, time and location information, various distributions of scholarly entities, and rising stars.

  11. The changing landscape of scholarly publishing: will radiation research survive?

    Science.gov (United States)

    Odell, Jere; Whipple, Elizabeth C

    2013-10-01

    As a society published journal, Radiation Research has been a successful and enduring project of the Radiation Research Society (RRS). In 59 years of publication, the journal has produced 732 issues and 10,712 articles. As a nonprofit organization, RRS, like most societies, has used revenues from subscriptions to support, in part, the life of the organization (meetings, conferences and grants to new scholars). The model for scientific publishing, however, continues to evolve. Radiation Research has weathered the rise of electronic publishing, consolidation in the commercial publishing industry, the aggregation of library subscriptions and library subscription cuts. Recent years have seen dramatic changes in how scholarly publishing is financed and new funder and institution policies will accelerate these changes. The growth of open access to journal articles reflects the information habits of readers and facilitates the dissemination of new knowledge. The Radiation Research Society, however, will need to account for and adapt to changes in the publishing market if it intends to support the communication of peer reviewed scholarship in the future.

    Campbell, Jacquelyn C; McBride, Angela Barron; Etcher, LuAnn; Deming, Katie

    The Robert Wood Johnson Foundation Nurse Faculty Scholars program was created to address the nursing shortage via development of the next generation of national leaders in academic nursing. The leadership training combined development at the scholar's home institution with in-person didactic and interactive sessions with notable leaders in nursing and other disciplines. A curriculum matrix, organized by six domains, was evaluated quantitatively and qualitatively. What set this program apart is that it immersed junior faculty in concerted leadership development with regard to all aspects of the faculty role so that teaching interactively, making use of the latest in information technology, giving testimony before a policy-making group, participating in strategic planning, and figuring out how to reduce the budget without jeopardizing quality were all envisioned as part of the faculty role. The domains covered by this program could easily be used as the framework to plan other leadership-development programs for the next generation of academic leaders. Copyright © 2017 Elsevier Inc.

  14. Opening access to African scholarly content: Stellenbosch University's AOARI platforms

    Directory of Open Access Journals (Sweden)

    Dr Reggie Raju

    2013-03-01

    Full Text Available Africa is viewed as a consumer of the world's knowledge production. A significant factor influencing this status is the low research output, with the main contributor to this status being minimum access to scholarly content to support research. Stellenbosch University, a leading research institution on the African continent, is committed to contributing to changing this status quo through the distribution of its own research output utilizing open sources. Given the challenges that have plagued Africa in developing processes for the distribution of their research, Stellenbosch University has developed the African Open Access Repository Initiative (AOARI which uses open source software for two platforms that support the ‘green’ and ‘gold’ route to sharing scholarly literature: Ubuntu is used as the operating system, DSpace is used for its repository and Open Journal Systems for its publication platform. It is anticipated that AOARI will be the bridge that facilitates the sharing of research output and nurtures a culture of research production in Africa.

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

    Science.gov (United States)

    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.

  18. Individual differences in personality change across the adult life span.

    Science.gov (United States)

    Schwaba, Ted; Bleidorn, Wiebke

    2017-05-16

    A precise and comprehensive description of personality continuity and change across the life span is the bedrock upon which theories of personality development are built. Little research has quantified the degree to which individuals deviate from mean-level developmental trends. In this study, we addressed this gap by examining individual differences in personality trait change across the life span. Data came from a nationally representative sample of 9,636 Dutch participants who provided Big Five self-reports at five assessment waves across 7 years. We divided our sample into 14 age groups (ages 16-84 at initial measurement) and estimated latent growth curve models to describe individual differences in personality change across the study period for each trait and age group. Across the adult life span, individual differences in personality change were small but significant until old age. For Openness, Conscientiousness, Extraversion, and Agreeableness, individual differences in change were most pronounced in emerging adulthood and decreased throughout midlife and old age. For Emotional Stability, individual differences in change were relatively consistent across the life span. These results inform theories of life span development and provide future directions for research on the causes and conditions of personality change. © 2017 Wiley Periodicals, Inc.

  19. Energetics and optimum motion of oscillating lifting surfaces of finite span

    Science.gov (United States)

    Ahmadi, A. R.; Widnall, S. E.

    1986-01-01

    In certain modes of animal propulsion in nature, such as bird flight and fish swimming, the efficiency compared to man-made vehicles is very high. In such cases, wing and tail motions are typically associated with relatively high Reynolds numbers, where viscous effects are confined to a thin boundary layer at the surface and a thin trailing wake. The propulsive forces, which are generated primarily by the inertial forces, can be calculated from potential-flow theory using linearized unsteady-wing theory (for small-amplitude oscillations). In the present study, a recently developed linearized, low-frequency, unsteady lifting-line theory is employed to calculate the (sectional and total) energetic quantities and optimum motion of an oscillating wing of finite span.

  20. Influence of Spanwise Boundary Conditions on Slat Noise Simulations

    Science.gov (United States)

    Lockard, David P.; Choudhari, Meelan M.; Buning, Pieter G.

    2015-01-01

    The slat noise from the 30P/30N high-lift system is being investigated through computational fluid dynamics simulations with the OVERFLOW code in conjunction with a Ffowcs Williams-Hawkings acoustics solver. In the present study, two different spanwise grids are being used to investigate the effect of the spanwise extent and periodicity on the near-field unsteady structures and radiated noise. The baseline grid with periodic boundary conditions has a short span equal to 1/9th of the stowed chord, whereas the other, longer span grid adds stretched grids on both sides of the core, baseline grid to allow inviscid surface boundary conditions at both ends. The results indicate that the near-field mean statistics obtained using the two grids are similar to each other, as are the directivity and spectral shapes of the radiated noise. However, periodicity forces all acoustic waves with less than one wavelength across the span to be two-dimensional, without any variation in the span. The spanwise coherence of the acoustic waves is what is needed to make estimates of the noise that would be radiated from realistic span lengths. Simulations with periodic conditions need spans of at least six slat chords to allow spanwise variation in the low-frequencies associated with the peak of broadband slat noise. Even then, the full influence of the periodicity is unclear, so employing grids with a fine, central region and highly stretched meshes that go to slip walls may be a more efficient means of capturing the spanwise decorrelation of low-frequency acoustic phenomena.

  2. Post-reproductive life span and demographic stability.

    Science.gov (United States)

    Mitteldorf, J J; Goodnight, C

    2013-09-01

    Recent field studies suggest that it is common in nature for animals to outlive their reproductive viability. Post-reproductive life span has been observed in a broad range of vertebrate and invertebrate species. But post-reproductive life span poses a paradox for traditional theories of life history evolution. The commonly cited explanation is the "grandmother hypothesis", which applies only to higher, social mammals. We propose that post-reproductive life span evolves to stabilize predator-prey population dynamics, avoiding local extinctions. In the absence of senescence, juveniles would be the most susceptible age class. If juveniles are the first to disappear when predation pressure is high, this amplifies the population's risk of extinction. A class of older, senescent individuals can help shield the juveniles from predation, stabilizing demographics and avoiding extinction. If, in addition, the life history is arranged so that the older individuals are no longer fertile, the stabilizing effect is further enhanced.

    2014-01-01

    To analyze the association between grip span of a manual flower cutting tool and maximum peak force exerted by each finger in the operating hand during apprehension. An experiment was conducted in which 11 women performed the stem cut of a flower. These women did not suffer from carpal tunnel syndrome. Grip span was calculated when they exerted the maximum peak force with each finger. The main finding of the study reveals that fingers exert the maximum peak force when the grip span values are the same for everyone. However, due to the shape of the tool commonly used in the Colombian flower industry (first order level), each finger reaches its maximum peak force at different times, bypassing the full capacity of each finger's grip force. These findings could be used to improve the mechanical advantage of manual cutting tools to reduce risk factors for carpal tunnel syndrome due to overexertion.

  4. Synergies between processing and memory in children's reading span.

    Towse, John N; Hitch, Graham J; Horton, Neil; Harvey, Katarina

    2010-09-01

    Previous research has established the relevance of working memory for cognitive development. Yet the factors responsible for shaping performance in the complex span tasks used to assess working memory capacity are not fully understood. We report a study of reading span in 7- to 11-year-old children that addresses several contemporary theoretical issues. We demonstrate that both the timing and the accuracy of recall are affected by the presence or absence of a semantic connection between the processing requirement and the memoranda. Evidence that there can be synergies between processing and memory argues against the view that complex span simply measures the competition between these activities. We also demonstrate a consistent relationship between the rate of completing processing operations (sentence reading) and recall accuracy. At the same time, the shape and strength of this function varies with the task configuration. Taken together, these results demonstrate the potential for reconstructive influences to shape working memory performance among children.

    To explore different allometric equations for scaling clearance across the human life-span using propofol as a model drug. Data from seven previously published propofol studies ((pre)term neonates, infants, toddlers, children, adolescents and adults) were analysed using NONMEM VI. To scale clearance, a bodyweight-based exponential equation with four different structures for the exponent was used: (I) 3/4 allometric scaling model; (II) mixture model; (III) bodyweight-cut-point separated model; (IV) bodyweight-dependent exponent model. Model I adequately described clearance in adults and older children, but overestimated clearance of neonates and underestimated clearance of infants. Use of two different exponents in Model II and Model III showed significantly improved performance, but yielded ambiguities on the boundaries of the two subpopulations. This discontinuity was overcome in Model IV, in which the exponent changed sigmoidally from 1.35 at a hypothetical bodyweight of 0 kg to a value of 0.56 from 10 kg onwards, thereby describing clearance of all individuals best. A model was developed for scaling clearance over the entire human life-span with a single continuous equation, in which the exponent of the bodyweight-based exponential equation varied with bodyweight.

  6. Extraordinary long life spans in fruit-feeding butterflies can provide window on evolution of life span and aging.

    Molleman, F; Zwaan, B J; Brakefield, P M; Carey, J R

    2007-06-01

    Information on the life span of organisms in the field is essential for elucidating the evolution of life span and aging. We present mark-recapture data (>30,000 marked individuals, >4000 recaptured at least once) on 47 species of fruit-feeding butterflies in a tropical forest in Uganda. The data reveal adult life spans in the field for several species that are significantly longer than previously recorded in Lepidoptera (butterflies and moths). Longevity records for species of which more than 100 individuals were recaptured ranged from 67 (Bicyclus auricruda) to 293 days (Euphaedra medon). In contrast to the majority of Lepidoptera which are short-lived, these all show exceptionally long life spans, and may thus help to better identify factors that affect aging, particularly when combined with information on temporal patterns in reproduction, strategies to avoid predation, and nutritional ecology. These key traits are readily measurable in butterflies and thus studies on fruit-feeding butterflies have much potential for gaining insight into the evolution of life span and aging, especially given the tradition of field-research on butterflies.

    2000-01-01

    Friendship occupies an important place in the growing body of literature in child development and gerontological research. As such, it may be useful for researchers from both fields to consider what can be learned from work carried out in each tradition. Therefore, we present a selected review of topics in friendship research across the life span. Through discussion of the value of friendship, the development of friendship, challenges to friendship, the gendered nature of friendship, and the connection between friends and family, points of commonality and contrast are identified. We conclude by presenting possible avenues for future investigation for researchers interested in friendship at any point in the life span.

    2011-08-05

    We report the generation of an octave-spanning optical frequency comb in a continuous wave laser pumped microresonator. The generated comb spectrum covers the wavelength range from 990 to 2170 nm without relying on additional external broadening. Continuous tunability of the generated frequency comb over more than an entire free spectral range is demonstrated. Moreover, the linewidth of individual optical comb components and its relation to the pump laser phase noise is studied. The ability to derive octave-spanning spectra from microresonator comb generators represents a key step towards f-2f self-referencing of microresonator-based optical frequency combs.

    2012-09-14

    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.

    Here, the purpose is to define the operational management structure and to delineate the responsibilities of key Space Physics Analysis Network (SPAN) individuals. The management structure must take into account the large NASA and ESA science research community by giving them a major voice in the operation of the system. Appropriate NASA and ESA interfaces must be provided so that there will be adequate communications facilities available when needed. Responsibilities are delineated for the Advisory Committee, the Steering Committee, the Project Scientist, the Project Manager, the SPAN Security Manager, the Internetwork Manager, the Network Operations Manager, the Remote Site Manager, and others.

  11. Open access and the future of scholarly communication

    CERN Document Server

    Dickson, Katherine A

    It is impossible to imagine the future of academic libraries without an extensive consideration of open access the removal of price and permission barriers from scholarly research online. As textbook and journal subscription prices continue to rise, improvements in technology make online dissemination of scholarship less expensive, and faculty recognize the practical and philosophical appeal of making their work available to wider audiences. As a consequences, libraries have begun to consider a wide variety of open access flavors and business models. These new possibilities have significant impact on both library services and collection policies, and the call for new skills within library staffing. Volume 9 of the series Creating the 21st-Century Academic Library is the first of two addressing the topic of open access in academic libraries and focuses on policy and infrastructure for libraries that wish to provide leadership on their campus in the transition to more open forms of scholarship.

    2014-08-01

    Full Text Available The Quick Response (QR code was first developed in 1994 by Denso Wave Incorporated, Japan. From that point on, it came into general use as an identification mark for all kinds of commercial products, advertisements, and other public announcements. In scholarly journals, the QR code is used to provide immediate direction to the journal homepage or specific content such as figures or videos. To produce a QR code and print it in the print version or upload to the web is very simple. Using a QR code producing program, an editor can add simple information to a website. After that, a QR code is produced. A QR code is very stable, such that it can be used for a long time without loss of quality. Producing and adding QR codes to a journal costs nothing; therefore, to increase the visibility of their journals, it is time for editors to add QR codes to their journals.

    2016-07-01

    Full Text Available Library-based publishing efforts are gaining traction in academic and research libraries across the world, primarily in response to perceived gaps in the scholarly publishing system. Though publishing is a new area of work for libraries, it is often a natural outgrowth of their existing infrastructure and skill sets, leveraging the institutional repository as publishing platform and repositioning librarians’ skills as information managers. For decades, these initiatives were primarily ad hoc and local, limiting the potential for library publishing to effect significant change. In 2013, over 60 academic and research libraries collectively founded the Library Publishing Coalition (LPC, a professional association expressly charged with facilitating knowledge sharing, collaboration and advocacy for this growing field. This article offers an overview of library publishing activity, primarily in the US, followed by an account of the creation and mission of the LPC, the first professional association dedicated wholly to the support of library publishers.

    Full Text Available This study is aimed to know the grammatical errors found in the articles’ abstracts of scholarly journals published by one of Indonesian Islamic State Colleges in 2008-2010. The theory used to analyze the data in this case study is Burt and Kiparsky’s theory, namely Surface Strategy Taxonomy. This theory devides errors into errors of omission, errors of addition, errors of misformation and errors of misordering. This results of the study show that there are 172 items of grammatical errors. The most frequent type of grammatical error is omission with the total number is 72 items or 41.9%. The second is errors of misformation which consist of 57 items or 33.1%. The next is errors of addition (27 items or 15.7% and finally is errors of misordering as the least number of errors with 16 items or 9.3%

    2017-03-01

    Full Text Available This work provides and analyzes an early institutional history of the pioneering Sherlock Holmes American fan club, the Baker Street Irregulars (BSI. Using the publications and records of these devoted Sherlockians, I track the BSI's development from a speakeasy gathering in 1934 to a national organization by the mid-1940s. This growth was built on a foundation of Victorian nostalgia and playful humor. Yet at the same time the members of the Irregulars took their fandom seriously, producing Sherlockian scholarship and creating an infrastructure of journals, conferences, and credentialing that directly mimicked the academy. They positioned themselves in contrast to prevailing scholarly practices of the period, such as New Criticism. I trace both how their fan practices developed over time and how this conflict with the academy led to many of the BSI's defining characteristics.

    Objective To delineate research resources available to otolaryngology residents and their impact on scholarly productivity. Study Design Survey of current otolaryngology program directors. Setting Otolaryngology residency programs. Subjects and Methods An anonymous web-based survey was sent to 98 allopathic otolaryngology training program directors. Fisher exact tests and nonparametric correlations were used to determine statistically significant differences among various strata of programs. Results Thirty-nine percent (n = 38) of queried programs responded. Fourteen (37%) programs had 11 to 15 full-time, academic faculty associated with the residency program. Twenty (53%) programs have a dedicated research coordinator. Basic science lab space and financial resources for statistical work were present at 22 programs (58%). Funding is uniformly provided for presentation of research at conferences; a minority of programs (13%) only funded podium presentations. Twenty-four (63%) have resident research requirements beyond the Accreditation Council for Graduate Medical Education (ACGME) mandate of preparing a "manuscript suitable for publication" prior to graduation. Twenty-five (67%) programs have residents with 2 to 3 active research projects at any given time. None of the investigated resources were significantly associated with increased scholarly output. There was no uniformity to research curricula. Conclusions Otolaryngology residency programs value research, evidenced by financial support provided and requirements beyond the ACGME minimum. Additional resources were not statistically related to an increase in resident research productivity, although they may contribute positively to the overall research experience during training. Potential future areas to examine include research curricula best practices, how to develop meaningful mentorship and resource allocation that inspires continued research interest, and intellectual stimulation.

  19. Adaptive Sentence Boundary Disambiguation

    CERN Document Server

    Palmer, D D; Palmer, David D.; Hearst, Marti A.

    1994-01-01

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

  20. The Bottom Boundary Layer.

    Trowbridge, John H; Lentz, Steven J

    2018-01-03

    The oceanic bottom boundary layer extracts energy and momentum from the overlying flow, mediates the fate of near-bottom substances, and generates bedforms that retard the flow and affect benthic processes. The bottom boundary layer is forced by winds, waves, tides, and buoyancy and is influenced by surface waves, internal waves, and stratification by heat, salt, and suspended sediments. This review focuses on the coastal ocean. The main points are that (a) classical turbulence concepts and modern turbulence parameterizations provide accurate representations of the structure and turbulent fluxes under conditions in which the underlying assumptions hold, (b) modern sensors and analyses enable high-quality direct or near-direct measurements of the turbulent fluxes and dissipation rates, and (c) the remaining challenges include the interaction of waves and currents with the erodible seabed, the impact of layer-scale two- and three-dimensional instabilities, and the role of the bottom boundary layer in shelf-slope exchange.

  2. Inside Out: Organizations as Service Systems Equipped with Relational Boundaries

    Directory of Open Access Journals (Sweden)

    María Jimena Crespo Garrido

    2017-04-01

    Full Text Available Currently, literature on organizational boundaries is at the center of a heated debate, characterized by a shift from a transactional approach to a broader immaterial perspective centered on the concept of boundless organizations. However, the overestimation of the effects of contemporary dematerialization on business processes can lead to the progressive neglect of the existence of corporate borders. In light of this consideration, the present work aims at proposing a new type of criterion for defining organizational boundaries, halfway between the conception of the firm’s total openness and total closure. To this end, the authors envisage the use of a new interpretive logic defined as “relational”, resulting from the specification of the systemic view (and as the sum of the logic underlying the viable systems approach (VSA. This approach views the definition of boundaries. Therefore, in the large and intricate scenery of the studies dedicated to organizational boundaries, this work contributes to a better understanding of border selection as an interactive and changeable process capable of pushing organizations towards a greater awareness of their strategic dimension. This paper also offers some insights for future research, suggesting that both scholars and professionals investigate, firstly, new frontiers for the identification of organizational boundaries and, secondly, the possible positive repercussions that new organizational redesign modes could determine for a greater competitive success.

    2015-01-01

    Objective Working memory refers to a cognitive system that manages information processing and temporary storage. Recent work has demonstrated that individual differences in working memory capacity measured using a reading span task are related to ability to recognize speech in noise. In this project, we investigated whether the specific implementation of the reading span task influenced the strength of the relationship between working memory capacity and speech recognition. Design The relationship between speech recognition and working memory capacity was examined for two different working memory tests that varied in approach, using a within-subject design. Data consisted of audiometric results along with the two different working memory tests; one speech-in-noise test; and a reading comprehension test. Study sample The test group included 94 older adults with varying hearing loss and 30 younger adults with normal hearing. Results Listeners with poorer working memory capacity had more difficulty understanding speech in noise after accounting for age and degree of hearing loss. That relationship did not differ significantly between the two different implementations of reading span. Conclusions Our findings suggest that different implementations of a verbal reading span task do not affect the strength of the relationship between working memory capacity and speech recognition.

    2013-01-01

    We outline a contextual and motivational model of judgment and decision-making (JDM) biases across the life span. Our model focuses on abilities and skills that correspond to deliberative, experiential, and affective decision-making processes. We review research that addresses links between JDM biases and these processes as represented by individual differences in specific abilities and skills (e.g., fluid and crystallized intelligence, executive functioning, emotion regulation, personality traits). We focus on two JDM biases—the sunk-cost fallacy (SCF) and the framing effect. We trace the developmental trajectory of each bias from preschool through middle childhood, adolescence, early adulthood, and later adulthood. We conclude that life-span developmental trajectories differ depending on the bias investigated. Existing research suggests relative stability in the framing effect across the life span and decreases in the SCF with age, including in later life. We highlight directions for future research on JDM biases across the life span, emphasizing the need for process-oriented research and research that increases our understanding of JDM biases in people’s everyday lives.

The test group included 94 older adults with varying hearing loss and 30 younger adults with normal hearing. Listeners with poorer working memory capacity had more difficulty understanding speech in noise after accounting for age and degree of hearing loss. That relationship did not differ significantly between the two different implementations of reading span. Our findings suggest that different implementations of a verbal reading span task do not affect the strength of the relationship between working memory capacity and speech recognition.

  3. 1-Skeletons of the Spanning Tree Problems with Additional Constraints

    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.

  7. Telomere Length Correlates with Life Span of Dog Breeds

    Directory of Open Access Journals (Sweden)

    Laura J. Fick

    2012-12-01

    Full Text Available 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 < 0.0001, consistent with telomeres playing a role in life span determination. 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.

Under their budget constraint, scholars and librarians are struggling for the choice of new medium for obtaining needed information goods and services, traditional publishers are developing operation schemes for electronic access to their intellectual assets, and governments are searching for optimal subsidy policies for acquisition of electronic resources. This study applies traditional economic approaches to scholarly electronic journal publishing. There are four basic economic issues that this study will address: scholars and libraries' demand for sources of scholarly articles, the production and distribution of scholarly journal, scholar electronic journal pricing strategies, and the externalities of shared information goods and services. Part 1 of this three-part article discusses the market economics of scholarly electronic journal publishing business work. It also describes choices among scholars, librarians, and publishers. It provides background for some of economic issues, as well as observations on the impact of new mediums on library resource acquisitions. Part 2 introduces the scholarly electronic journal publishing's market structure, pricing strategies, and barriers to entry in the publishing industry.

    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

  7. Method Suitable for Updating the Boundary Condition of Continuous Beam Bridges

    Cao, JianXin; Zheng, Honglan; Liu, Yang

    2017-10-01

    The boundary support conditions of continuous beam bridges play the great influence on the results of the structural analysis, but it is difficult to accurately model the boundaries owing to the complexity structure of constraint conditions. To address this issue, a parameterized method is proposed to update the boundary support conditions in this study. First, the connection stiffness at boundary is considered as the optimization variable, and then the optimization problem of updating the boundary conditions are described in detail based on the theory of finite element model updating. Second, for verifying the proposed method, a loading test was conducted on an actual three-span continuous beam bridge. With the proposed method, the discrepancy between the measured modal parameters and the analytical results are greatly reduced; therefore, it is shown that the proposed method is effective for updating the boundary support conditions of actual continuous beam bridges.

  8. Grain Boundary Segregation in Metals

    CERN Document Server

    Lejcek, Pavel

    2010-01-01

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

    Safety, quality improvement, and a systems perspective are vital for nurses to provide quality evidence-based care. Responding to the call to prepare nurses with these perspectives, one school of nursing used a clinical scholar approach, enhanced by systems engineering to more intentionally develop the ability to clinically reason and apply evidence-based practice. A two-group, repeated-measures control trial was used to determine the effects of systems engineering content and support on nursing students' clinical judgment and critical thinking skills. Findings indicated this approach had a positive effects on student's clinical judgment and clinical reasoning skills. This approach helped students view health care issues from a broader perspective and use evidence to guide solution development, enhancing the focus on evidence-based practice, and quality improvement. Intentional integration of an evidence-based, systems perspective by nursing faculty supports development of nurses who can function safely and effectively in the current health care system.

    Directory of Open Access Journals (Sweden)

    Manuel Gil Antón

    2000-05-01

    Full Text Available Dr. Gil questions the role played by Mexican university academics in the transformation of higher education during the nineties. After outlining the general context of change and its importance, the author proposes avoiding the false dichotomy between restoring the past or installing, without reflective mediation, a schematic future. He suggests taking into consideration the current national academic body composed of several generations of scholars. Three phases are established in terms of the modification of academic activities during the last decades of the twentieth century, and the changes in the level of higher education are considered. Dr. Gil asks if the academics have been actors, subjects, spectators or hostages-both in regard to regulations governing their activity and in the modifications of university processes and structure. The essay ends by proposing a general agenda for research in the field of university studies, and emphasizes two problems: the need for a detailed description of the type and depth of changes, and the definition of the academic as a central actor in institutional life.

    Although the importance of research mentorship has been well established, the role of mentors of junior clinical and translational science investigators is not clearly defined. The authors attempt to derive a list of actionable competencies for mentors from a series of complementary methods. We examined focus groups, the literature, competencies derived for clinical and translational scholars, mentor training curricula, mentor evaluation forms and finally conducted an expert panel process in order to compose this list. These efforts resulted in a set of competencies that include generic competencies expected of all mentors, competencies specific to scientists, and competencies that are clinical and translational research specific. They are divided into six thematic areas: (1) Communication and managing the relationship, (2) Psychosocial support, (3) Career and professional development, (4) Professional enculturation and scientific integrity, (5) Research development, and (6) Clinical and translational investigator development. For each thematic area, we have listed associated competencies, 19 in total. For each competency, we list examples that are actionable and measurable. Although a comprehensive approach was used to derive this list of competencies, further work will be required to parse out how to apply and adapt them, as well future research directions and evaluation processes. © 2012 Wiley Periodicals, Inc.

  12. The Prevalence of Reading Difficulties among Children in Scholar Age

    2014-10-01

    Full Text Available The study investigates the prevalence of reading difficulties among children in scholar age and analyses the socio-demographic characteristics of learners who presented reading difficulties in central Italy. A sample of 623 students 7-11 aged, was assessed with the Italian MT standardized tests. Information on gender, age, handedness, and other socio-demographic variables were also gathered. The study showed that 11% of learners presented poor comprehension skills. The reading speed difficulties were more common than the reading correctness problems: about 7% of children vs 1% were dyslexics due to slow reading. There were no significant differences regarding gender, age. However, dominant hand and the school location seemed to affect the speed difficulties and the comprehension problems. The analyses showed that attending a school located in a rural area was statistically associated with the reading difficulties. Left-handed children were more likely to be slow decoders and/or poor comprehenders. These findings may be used in the early diagnosis of poor readers. These difficulties often have a chronic progression with substantial psychosocial limitations and psychological stress, so children with reading difficulties should be identified as early as possible.

  13. Evolution of the scholarly mega-journal, 2006-2017.

    2018-01-01

    Mega-journals are a new kind of scholarly journal made possible by electronic publishing. They are open access (OA) and funded by charges, which authors pay for the publishing services. What distinguishes mega-journals from other OA journals is, in particular, a peer review focusing only on scientific trustworthiness. The journals can easily publish thousands of articles per year and there is no need to filter articles due to restricted slots in the publishing schedule. This study updates some earlier longitudinal studies of the evolution of mega-journals and their publication volumes. After very rapid growth in 2010-2013, the increase in overall article volumes has slowed down. Mega-journals are also increasingly dependent for sustained growth on Chinese authors, who now contribute 25% of all articles in such journals. There has also been an internal shift in market shares. PLOS ONE, which totally dominated mega-journal publishing in the early years, currently publishes around one-third of all articles. Scientific Reports has grown rapidly since 2014 and is now the biggest journal.

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

    Science.gov (United States)

    Gadelrab, Sherry Sayed

    2011-01-01

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

  15. Normalizing Google Scholar data for use in research evaluation.

    Mingers, John; Meyer, Martin

    2017-01-01

    Using bibliometric data for the evaluation of the research of institutions and individuals is becoming increasingly common. Bibliometric evaluations across disciplines require that the data be normalized to the field because the fields are very different in their citation processes. Generally, the major bibliographic databases such as Web of Science (WoS) and Scopus are used for this but they have the disadvantage of limited coverage in the social science and humanities. Coverage in Google Scholar (GS) is much better but GS has less reliable data and fewer bibliometric tools. This paper tests a method for GS normalization developed by Bornmann et al. (J Assoc Inf Sci Technol 67:2778-2789, 2016) on an alternative set of data involving journal papers, book chapters and conference papers. The results show that GS normalization is possible although at the moment it requires extensive manual involvement in generating and validating the data. A comparison of the normalized results for journal papers with WoS data shows a high degree of convergent validity.

    Full Text Available The World Council of Churches (WCC, an organization of 348 member churches, is a model of coalition building particularly through its support of individuals, churches, and their ministries for the inclusion, participation, and contributions of people with disabilities in its ecumenical work. The Ecumenical Disability Advocates Network (EDAN informs one of the initiatives of the WCC—faith in Jesus Christ and communion fellowship—in the journey toward visible unity and justice for people who were too often missing the banquet of a church of all and for all. EDAN and other international disability advocates have most recently embedded its agenda of inclusion into the United Nations Sustainable Development Goals. The United Nations explicitly recognizes the Human Rights for persons with disabilities and, with the Convention of the Rights of Persons with Disabilities (2006, has raised protections against discrimination, exploitation, and abuse of people with disabilities to the level of international law. The World Health Organization works collaboratively in gathering data and local analyses of efforts to minimize preventable disability and maximize rehabilitation program availability with partners across the globe. These organizations, global in nature, have benefitted from the insights raised by people with disabilities and scholars working at the intersections of disability, religion, and justice. This essay examines the efficacy and opportunities of international coalitions available with these organizations so as to challenge the ethics of simple accommodations with a more robust social justice of affirmation and advocacy for people with disabilities: a new paradigm for our churches and our world.

    This study was designed to investigate changes in fundamental frequency (F0) across the life span in Persian speakers. Four hundred children and adults were asked to produce a sustained phonation of vowel /a/ and their voice samples were studied in 10 age groups. F0 was analyzed using the software Praat (Version 5.1.17.). The results revealed that (1) the mean F0 in both sexes decreases from childhood to adulthood; (2) significant F0 differences between boys and girls begin at the age of 12 years; and (3) the range of F0 changes in the life span is greater in men (178.38 Hz) than in women (113.57 Hz). These findings provide new data for Persian-speaking children, women, and men and could be beneficial for Iranian speech and language pathologists. Copyright © 2014 The Voice Foundation.

  1. Modelling ecosystem service flows under uncertainty with stochiastic SPAN

    Ecosystem service models are increasingly in demand for decision making. However, the data required to run these models are often patchy, missing, outdated, or untrustworthy. Further, communication of data and model uncertainty to decision makers is often either absent or unintuitive. In this work, we introduce a systematic approach to addressing both the data gap and the difficulty in communicating uncertainty through a stochastic adaptation of the Service Path Attribution Networks (SPAN) framework. The SPAN formalism assesses ecosystem services through a set of up to 16 maps, which characterize the services in a study area in terms of flow pathways between ecosystems and human beneficiaries. Although the SPAN algorithms were originally defined deterministically, we present them here in a stochastic framework which combines probabilistic input data with a stochastic transport model in order to generate probabilistic spatial outputs. This enables a novel feature among ecosystem service models: the ability to spatially visualize uncertainty in the model results. The stochastic SPAN model can analyze areas where data limitations are prohibitive for deterministic models. Greater uncertainty in the model inputs (including missing data) should lead to greater uncertainty expressed in the model’s output distributions. By using Bayesian belief networks to fill data gaps and expert-provided trust assignments to augment untrustworthy or outdated information, we can account for uncertainty in input data, producing a model that is still able to run and provide information where strictly deterministic models could not. Taken together, these attributes enable more robust and intuitive modelling of ecosystem services under uncertainty.

  2. Indoor Positioning Using Nonparametric Belief Propagation Based on Spanning Trees

    2010-01-01

    Nonparametric belief propagation (NBP) is one of the best-known methods for cooperative localization in sensor networks. It is capable of providing information about location estimation with appropriate uncertainty and to accommodate non-Gaussian distance measurement errors. However, the accuracy of NBP is questionable in loopy networks. Therefore, in this paper, we propose a novel approach, NBP based on spanning trees (NBP-ST) created by breadth first search (BFS) method. In addition, we pr...

  4. Investigation of span-chordwise bending anisotropy of honeybee forewings

    JianGuo Ning

    2017-05-01

    Full Text Available In this study, the spanwise and chordwise bending stiffness EI of honeybee forewings were measured by a cantilevered bending test. The test results indicate that the spanwise EI of the forewing is two orders of magnitude larger than the chordwise EI. Three structural aspects result in this span-chordwise bending anisotropy: the distribution of resilin patches, the corrugation along the span and the leading edge vein of the venation. It was found that flexion lines formed by resilin patches revealed through fluorescence microscopy promoted the chordwise bending of the forewing during flapping flight. Furthermore, the corrugation of the wing and leading edge veins of the venation, revealed by micro-computed tomography, determines the relatively greater spanwise EI of the forewing. The span-chordwise anisotropy exerts positive structural and aerodynamic influences on the wing. In summary, this study potentially assists researchers in understanding the bending characteristics of insect wings and might be an important reference for the design and manufacture of bio-inspired wings for flapping micro aerial vehicles.

  5. Simultaneous prediction of protein secondary structure and transmembrane spans.

    Prediction of transmembrane spans and secondary structure from the protein sequence is generally the first step in the structural characterization of (membrane) proteins. Preference of a stretch of amino acids in a protein to form secondary structure and being placed in the membrane are correlated. Nevertheless, current methods predict either secondary structure or individual transmembrane states. We introduce a method that simultaneously predicts the secondary structure and transmembrane spans from the protein sequence. This approach not only eliminates the necessity to create a consensus prediction from possibly contradicting outputs of several predictors but bears the potential to predict conformational switches, i.e., sequence regions that have a high probability to change for example from a coil conformation in solution to an α-helical transmembrane state. An artificial neural network was trained on databases of 177 membrane proteins and 6048 soluble proteins. The output is a 3 × 3 dimensional probability matrix for each residue in the sequence that combines three secondary structure types (helix, strand, coil) and three environment types (membrane core, interface, solution). The prediction accuracies are 70.3% for nine possible states, 73.2% for three-state secondary structure prediction, and 94.8% for three-state transmembrane span prediction. These accuracies are comparable to state-of-the-art predictors of secondary structure (e.g., Psipred) or transmembrane placement (e.g., OCTOPUS).

    Quantum surface effects (new emission bands, blueshifts, intensity enhancement) were observed in SPAN-80 activated ZnS nanocolloids and explained in terms of time-dependent density functional theory. The experimental evidences were demonstrated for both undoped and Cu, Mn-doped colloidal phases. The photoluminescence spectra of these materials showed a new green band at 520 nm (ZnS:Cu) and a yellow-orange band at 576 nm (ZnS:Mn) besides a blue band at 465 nm. All bands lie in the visible region and are blueshifted, show sharp emissions with narrow widths and have approximately 20-times stronger intensities in comparison with those of the bulk samples. The time-resolved luminescence spectra showed that the life-times of free electrons were 0.12 {mu}s and 1.9 ms in ZnS:Cu and ZnS:Mn correspondingly. - Highlights: Black-Right-Pointing-Pointer Novel SPAN-80 activated ZnS nanocolloids with new observables. Black-Right-Pointing-Pointer Enhanced emission intensity of colloidal systems activated by SPAN-80.

    1989-12-01

    A review is presented of the contributions to understanding historical and cultural variation in drinking practices from three disciplines--epidemiology, life-span developmental psychology and the sociology of aging. It is concluded that while these disciplines have made major methodological contributions to understanding these variations, theory is lacking. Reasons for the paucity of theory and the lack of hypotheses are advanced, as are frameworks in which to test competitive hypotheses across temporal and cultural boundaries.

  9. Measuring the Substellar Boundary

    2018-01-01

    Brown dwarfs are not massive enough to undergo hydrogen fusion and therefore constantly lose heat and change luminosity over their lifetime. Because of this, brown dwarfs do not follow the same pattern that stars on the main sequence follow. Brown dwarfs can have similar luminosities but widely differing masses, or vice versa, while stars follow a tight relationship between mass and luminosity. In principle, mass and luminosity measurements straddling the boundary between stars and brown dwarfs could be used to directly measure this dividing line in mass. We present a method for determining this boundary accurately given a limited sample size. We tested our method with Monte Carlo simulated samples of brown dwarfs and stars with randomly drawn masses and ages, using evolutionary models to infer luminosities. In our simulation designed to mimic the largest current sample of such mass measurements (37 objects; Dupuy & Liu 2017), we find that the uncertainty in the dividing line that can be inferred from the data is ± 4 MJup. This implies that distinguishing between competing evolutionary model predictions for the boundary (~70-80 MJup) will be difficult given the current sample size of mass measurements.
