    2001-01-01

    Full Text Available Tilting-pad journal bearings are widely used to promote stability in modern rotating machinery. However, the dynamics associated with pad motion alters this stabilizing capacity depending on the operating speed of the machine and the bearing geometric parameters, particularly the bearing preload. In modeling the dynamics of the entire rotor-bearing system, the rotor is augmented with a model of the bearings. This model may explicitly include the pad degrees of freedom or may implicitly include them by using dynamic matrix reduction methods. The dynamic reduction models may be represented as a set of polynomials in the eigenvalues of the system used to determine stability. All tilting-pad bearings can then be represented by a fixed size matrix with polynomial elements interacting with the rotor. This paper presents a procedure to calculate the coefficients of polynomials for implicit bearing models. The order of the polynomials changes to reflect the number of pads in the bearings. This results in a very compact and computationally efficient method for fully including the dynamics of tilting-pad bearings or other multiple degrees of freedom components that interact with rotors. The fixed size of the dynamic reduction matrices permits the method to be easily incorporated into rotor dynamic stability codes. A recursive algorithm is developed and presented for calculating the coefficients of the polynomials. The method is applied to stability calculations for a model of a typical industrial compressor.

    Full Text Available Aiming at fault diagnosis for tilting-pad journal bearing with fluid support developed recently, a new method based on singular value decomposition (SVD and local mean decomposition (LMD is proposed.

  16. Nonlinear Dynamics Analysis of Tilting Pad Journal Bearing-Rotor System

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available The nonlinear dynamics theory is increasingly applied in the dynamics analysis of tilting pad journal bearing-rotor system. However, extensive work on system dynamics done previously neglects the influence caused by the moment of inertia of the pad. In this paper, a comparison is made between the responses of the rotor in the bearings with and without pad inertia effect. Taking the Jeffcott rotor system as an example, the characteristics of bearing-rotor system, such as bifurcation diagram, cycle response, frequency spectrum, phase trajectories, and Poincaré maps, were attained within a certain rotation rate range. The pivotal oil-film force of tilting pad journal bearing was calculated by database method. The results directly demonstrate that considering the influence of the pad moment of inertia, system dynamics characteristics are found more complicated when rotor-bearing system works around natural frequency and system bifurcation is observed forward when rotor-bearing system works on high-speed range.

    The present work concerns the realization of a test bench for the dynamic characterization of high performance tilting pad journal bearings, within a collaboration between the Department of Civil and Industrial Engineering of Pisa, GE Oil&Gas and AM Testing. The objective is to cover journal diameters of interest of GE, from 150 to 300 mm, with peripheral speeds up to 150 m/s, static load up to 270 kN, dynamic loads up to 30 kN and frequencies up to 350 Hz, performances that make the apparatus very competitive worldwide. The adopted configuration has the test article (TA) floating at the mid-span of a rotor supported by two rolling bearings. The TA is statically loaded by a hydraulic actuator and excited dynamically by two orthogonal hydraulic actuators. Construction was recently concluded and preliminary tests are under way. In order to assess in advance the possible accuracy of the tests, a dynamic lumped parameter model of the test bench was developed to perform virtual experiments, including several possible sources of experimental errors and uncertainties. The model was implemented using reduced stiffness and mass matrices obtained from Finite Element Analysis by Component Modal Synthesis.

    The journal bearings with multiple tilting pads are widely used to support the shaft assembly of turbo generators. With the considerations of variable viscosity and density, a model of tilting-pad journal bearing with multiple-pads was established, and was analyzed using finite difference method. A computer program was developed to calculate the minimum film thickness, pressure distribution and three-dimensional temperature distribution of each pad, and the effects of radial loads, rotational speeds and oil viscosity grades of nine cases on the thermal hydrodynamic lubrication ( THD ) of the bearings were analyzed.

    2000-01-01

    Full Text Available A new numerical method is proposed for predicting the nonlinearity of tilting-pad guide bearing oilfilm force in the rotor-bearing system in a large hydro-unit. Nonlinear displacement and velocity of the journal center, as well as nonlinear tilting angles and angular velocities of the pads in non-stationary Reynolds equation are taken into account. This method is also suited for other small rotor-bearing system. As an example, the response due to a momentarily created unbalance is Calculated. The nonlinear motion patterns of the pad and journal whirling orbit are obtained. Finally, the nonlinear orbit is compared to the linear one that could be calculated from linear stiffness and damping coefficients. It is shown that there are important differences between those two orbits and that the nonlinear simulation is more accurate.

    The phenomena liable to affect the behaviour of a four-tilting-pad journal bearing, i.e. elastic deformations of the pad due to hydrodynamic pressures generated in the film, load-induced crushing of the pad at the interface with the support, and thermal effects in the lubricating film, have been quantified for two unbalance eccentricities. These effects mainly modify the amplitude of the trajectory of the center of the shaft. The pads, free in rotation on their pivot, can adapt to the operating conditions, inducing small variations in the minimum film thicknesses or maximum pressures. Once the three phenomena have been isolated, a general calculation is carried out for an unbalance eccentricity of 40 micrometers, considering elastic deformations, crushing and thermal effects. Since temperature variations over time are low, thermal dilatation of the solid components are also considered through the use of machining and assembly clearance values that have been experimentally determined. Results are compared with those obtained by traditional calculation methods, namely isothermal theory and rigid pad

    A new type of tilting-pad gas seal is referred Compared to traditional fixed gas seal, the seal block of tilting-pad seal can swing about a pivot automatically under the air force. The stability can be improved through reducing the tangential force when the seal pads reach equilibrium position. The dynamic characteristics of tilting-pad seal are tested by experiment using unbalance synchronous frequency excitation method. Also, the experiment is taken to compare the characteristics of two kinds of seals. The result shows that the leakage of tilting-pad seal is close to fixed seal, and the tangential force generated in tilting-pad seal is smaller than the fixed. The rotordynamic coefficients of two kinds of seals are tested under different pressure ratios. It is shown that the rotordynamic coefficients are almost equal in low pressure ratio, but the difference between two seals increases as the pressure ratio increasing. The work acted on cylinder system is used as standard to judge the stability of seal. The calculation result shows that the fixed seal does more work than tilting-pad seal to cylinder system. As the increasing of pressure ratio, the work difference increases, so the tilting-pad seal has higher stability. For the real large rotating machines, the inlet/outlet pressure ratio is very high, so the difference between these two kinds of seals is larger.%提出一种新型可倾气封.与传统固定式气封相比,可倾气封块在气流力作用下可以绕支点作自适应摆动,当气封块达到平衡位置时,切向激振力减小,从而提高稳定性.试验采用不平衡同频激励法测定可倾气封的动力特性,研究和比较了可倾气封和传统固定式气封的动静态性能.试验结果表明,两种气封泄漏量相当,可倾气封内产生的切向气流力比固定气封小.低压比下两种气封动力特性系数相近,随着压比的增大,动力特性系数差异逐渐增大.以气流力对气缸的做功量大小为综

The result shows that the calculation program operates stably and reli-ably. Besides, the lubricating character of guide bearing is affected by factors including bearing load, unit speed and inlet oil temperature of oil tank. The maximum oil film temperature and the minimum oil film thickness become the critical factor restricting the variation range of operating parameters.

    Full Text Available Activity theory is a relevant framework for the Design field, and their graphic representations are cognitive artifacts that aid the understanding, use and communication of this theory. However, there is a lack of consistency around the graphics and labels used in these representations. Based on this, the aim of this study was to identify, analyze and evaluate these differences and propose a representation that aims to be more suitable for the theory. For this, uses as method a literature review based on Engeström (2001 and its three generations of visual models, combined with graphical analysis of representations collected in a hundred papers from international journals.

    2016-09-01

    Because of the advantages of high accuracy, high capacity, and low friction, the development of hydrostatic bearing for machine tool receives significant attention in the last decades. The mechanics and mechanical design of hydrostatic journal bearing with capillary restrictors has been discussed in literature. However, pragmatically, the undesired loading effects of cutting force tend to result in resonance and instability of the rotor and damage the shaft during operation. Therefore, multi-input, active flow control using state feedback design is proposed in this paper. To this purpose, the proportional pressure valves are added to the hydraulic system as active control devices, and the linearised models of the bearing and valve are discussed and identified. Simulation and experimental work is conducted to verify the proposed active control and parameter identification techniques. The results show that the unbalance responses of the rotor are reduced by the proposed state feedback controller, which is able to regulate the flow pressure effectively, thus enhancing the stability and accuracy of the hydraulic journal bearing.

    Full Text Available In this article, which reports the second part of a two-part study of the use of electronic journals by researchers in two French research institutions, we attempt to explain the integration of the use of electronic journals in the scientists' information habits, going beyond usage analysis. First, we describe how the development of electronic journals use follows a three-phase innovation process - research-development, first uses, and technical acculturation. Then, we attempt to find more significant explanatory factors, and emphasis is placed on the wider context of information activity. Three main information activity types are outlined - marginal, parallel, and integrated. Each of these types corresponds to a particular attitude towards scientific information and to different levels of electronic journal use.

    Hanford, Amanda; Campbell, Robert

    2012-01-01

    The wave bearing software suite is a MALTA application that computes bearing properties for user-specified wave bearing conditions, as well as plain journal bearings. Wave bearings are fluid film journal bearings with multi-lobed wave patterns around the circumference of the bearing surface. In this software suite, the dynamic coefficients are outputted in a way for easy implementation in a finite element model used in rotor dynamics analysis. The software has a graphical user interface (GUI) for inputting bearing geometry parameters, and uses MATLAB s structure interface for ease of interpreting data. This innovation was developed to provide the stiffness and damping components of wave bearing impedances. The computational method for computing bearing coefficients was originally designed for plain journal bearings and tilting pad bearings. Modifications to include a wave bearing profile consisted of changing the film thickness profile given by an equation, and writing an algorithm to locate the integration limits for each fluid region. Careful consideration was needed to implement the correct integration limits while computing the dynamic coefficients, depending on the form of the input/output variables specified in the algorithm.

    2017-07-01

    The advantage of journal hydrodynamic bearings is high radial load capacity and operation at high speeds. The disadvantage is the excitation of vibrations, called an oil whirl, after crossing a certain threshold of the rotational speed. The mentioned vibrations can be suppressed using the system of the active vibration control with piezoactuators which move the bearing bushing. The motion of the bearing bushing is controlled by a feedback controller, which responds to the change in position of the bearing journal which is sensed by a pair of capacitive sensors. Two stacked linear piezoactuators are used to actuate the position of the bearing journal. This new bearing enables not only to damp vibrations but also serves to maintain the desired bearing journal position with an accuracy of micrometers. The paper will focus on the effect of active vibration control on the performance characteristics of the journal bearing.

    Medical journals use social media as a means to disseminate new research and interact with readers. The microblogging site Twitter is one such platform. The aim of this study was to analyze the recent use of Twitter by the leading radiology journals. The top 50 journals by Impact Factor were included. Twitter profiles associated with these journals, or their corresponding societies, were identified. Whether each journal used other social media platforms was also recorded. Each Twitter profile was analyzed over a one-year period, with data collected via Twitonomy software. Klout scores of social media influence were calculated. Results were analyzed in SPSS using Student's t test, Fisher contingency tables, and Pearson correlations to identify any association between social media interaction and Impact Factors of journals. Fourteen journals (28%) had dedicated Twitter profiles. Of the 36 journals without dedicated Twitter profiles, 25 (50%) were associated with societies that had profiles, leaving 11 (22%) journals without a presence on Twitter. The mean Impact Factor of all journals was 3.1 ± 1.41 (range, 1.7-6.9). Journals with Twitter profiles had higher Impact Factors than those without (mean, 3.37 vs 2.14; P journals with dedicated Twitter profiles and those associated with affiliated societies (P = .47). Since joining Twitter, 7 of the 11 journals (64%) experienced increases in Impact Factor. A greater number of Twitter followers was correlated with higher journal Impact Factor (R(2) = 0.581, P = .029). The investigators assessed the prevalence and activity of the leading radiology journals on Twitter. Radiology journals with Twitter profiles have higher Impact Factors than those without profiles, and the number of followers of a journal's Twitter profile is positively associated with Impact Factor.

  5. Vibration Control in Turbomachinery Using Active Magnetic Journal Bearings

    Knight, Josiah D.

    1996-01-01

    The effective use of active magnetic bearings for vibration control in turbomachinery depends on an understanding of the forces available from a magnetic bearing actuator. The purpose of this project was to characterize the forces as functions shaft position. Both numerical and experimental studies were done to determine the characteristics of the forces exerted on a stationary shaft by a magnetic bearing actuator. The numerical studies were based on finite element computations and included both linear and nonlinear magnetization functions. Measurements of the force versus position of a nonrotating shaft were made using two separate measurement rigs, one based on strain gage measurement of forces, the other based on deflections of a calibrated beam. The general trends of the measured principal forces agree with the predictions of the theory while the magnitudes of forces are somewhat smaller than those predicted. Other aspects of theory are not confirmed by the measurements. The measured forces in the normal direction are larger than those predicted by theory when the rotor has a normal eccentricity. Over the ranges of position examined, the data indicate an approximately linear relationship between the normal eccentricity of the shaft and the ratio of normal to principal force. The constant of proportionality seems to be larger at lower currents, but for all cases examined its value is between 0.14 and 0.17. The nonlinear theory predicts the existence of normal forces, but has not predicted such a large constant of proportionality for the ratio. The type of coupling illustrated by these measurements would not tend to cause whirl, because the coupling coefficients have the same sign, unlike the case of a fluid film bearing, where the normal stiffness coefficients often have opposite signs. They might, however, tend to cause other self-excited behavior. This possibility must be considered when designing magnetic bearings for flexible rotor applications, such as gas

    Evidence-based medicine (EBM) journal clubs are used by health care practitioners to critique and remain updated on relevant health literature. Vote cards, in three different colours (green/yellow/red), allow participants to express their opinions (agree/doubt/reject) on the quality and possibility of clinical application regarding the article being reviewed. Our aim is to assess the efficacy of using vote cards in EBM journal clubs. Evidence-based medicine journal club is held on a weekly basis in the Department of Surgery in Taipei Medical University Hospital, Taiwan. The participants of EBM journal clubs include medical students, resident doctors and primary care faculty members. After the presentation, participants use their vote cards to critically appraise the literature and decide if the rationales could be applied in their own practice. After a 12-week period, we evaluated the effectiveness of the vote cards based on survey findings of the participants. The majority of 66 respondents agreed that vote cards can improve the overall quality of EBM journal clubs, may encourage active participation and improve critical appraisal skills. They also rated the vote cards more favourably than traditional hand voting and agree that vote cards should be used in future EBM journal clubs. We suggest the regular and routine use of vote cards in EBM journal clubs. © 2011 Blackwell Publishing Ltd.

  8. Numerical and Experimental Stability Investigation of a Flexible Rotor on Two Different Tilting Pad Bearing Configurations

    Directory of Open Access Journals (Sweden)

    Weimin Wang

    2014-01-01

    Full Text Available Rotordynamic stability is crucial for high performance centrifugal compressors. In this paper, the weighted instrumental variable (WIV based system identification method for rotating machinery stability is investigated based on a sine sweep forward excitation with an electromagnetic actuator. The traditional multiple input multiple output (MIMO frequency response function (FRF is transformed into a directional frequency response function (dFRF. The rational polynomial method (RPM combined with WIV is developed to identify the rotor’s first forward mode parameters. This new approach is called the COMDYN method. Experimental work using the COMDYN method is carried out under different rotating speeds, oil inlet temperatures, and pressure conditions. Two sets of bearings with preloads 0.1 and 0.3 are investigated. A numerical rotor-bearing model is also built. The numerical results correlate reasonably well with the experimental results. The investigation results indicate that the new method satisfies the desired features of rotating machine stability identification. Furthermore, the system log decrement was improved somewhat with the increase of oil inlet temperature. The increase of oil supply pressure affects the rotor-bearing system stability very slightly. The results of this paper provide new and useful insights for potentially avoiding instability faults in centrifugal compressors.

  18. [CME activities of medical journals: quality of multiple-choice questions as evaluation tool. Using the example of the German medical journals Deutsches Arzteblatt, Deutsche Medizinische Wochenschrift, and Der Internist].

    2007-12-15

    The participation of doctors in Continuing Medical Education (CME) activities provided by medical journals increases. Therefore, their quality and efficacy need to be evaluated. This study evaluated the quality of the multiple-choice questions (MCQs) as evaluation tool of CME activities in three German medical journals (Der Internist, Deutsches Arzteblatt, Deutsche Medizinische Wochenschrift). In total, 390 MCQs were reviewed using evidence-based principles of effective item writing. The content quality of the MCQs was not evaluated in this study. 264 (67.7%) of 390 MCQs contained flaws with 449 flaws in total. The proportion of flawed items was 60.8% in Deutsches Arzteblatt, 63.3% in Der Internist, and 77.9% in Deutsche Medizinische Wochenschrift. The most frequent flaws were clues (33.8%, Deutsches Arzteblatt), negatively worded stems (29.8%, Der Internist), and unfocused stems (24.7%, Deutsche Medizinische Wochenschrift). SCHLUSSFOLGERUNG: The problem of formal flaws in MCQs has an extensive relevance, as seen by the large number of studies related to this topic. The frequency of flaws (67.7%) was similar to recent studies. The distribution of the flaws suggests that with minor editing the quality of the MCQs could be substantially improved. The use of high-quality evaluation tools is essential to invalidate the accusation of the trivialization of CME activities, irrespective of their social context.

  19. Journal standards.

    Science.gov (United States)

    Jackson, R

    2003-08-01

    Despite its many imperfections, the peer review process is a firmly established quality control system for scientific literature. It gives readers some assurance that the work and views that are reported meet standards that are acceptable to a journal. Maureen Revington's editorial in a recent issue of the Australian Veterinary Journal (Revington2002) gives a good concise warts and all overview of the process and is well worth reading. I have some concerns about several articles in the December 2002 issue of the New Zealand Veterinary Journal (Volume 50, Number 6), devoted to the health and welfare of farmed deer, that relate to extensive citing of non-peer reviewed papers. I can understand the need for information to flow from researchers to the wider community but that need is already satisfied by publications such as the proceedings of the Deer Branch of the New Zealand Veterinary Association and Proceedings of the New Zealand Society of Animal Production. Non-peer reviewed papers have been cited in the Journal in the past but never to the extent displayed in this particular issue. It degrades the peer-review process and creates an added burden for reviewers who are forced to grapple with the uncertainties of the science in non-peer reviewed citations. One of my fears is that this process allows science from non peer reviewed articles to be legitimised by its inclusion in a peer reviewed journal and perhaps go on to be accepted as dogma. This is a real danger given the difficulties associated with tracing back to original citations and the increasing volume of scientific literature. It also affords opportunities for agencies to pick up questionable and doubtful science and tout it as support for their products or particular points of view. If deer researchers choose to publish most of their work in proceedings then so be it. However this approach, which seems to becoming increasingly prevalent in the deer sector, is questionable from an established science point

  4. Good journalism or peace journalism?

    Directory of Open Access Journals (Sweden)

    David Loyn

    2007-10-01

    Full Text Available This paper argues against the prescriptive notions of Peace Journalism, and in particular its exclusive nature and attempt to define itself as a new orthodoxy. Most of the paper is a critique of the work of Jake Lynch and Annabel McGoldrick, in a book published in 2005, as well as their earlier Reporting the World series. They condemn all other ways of reporting as 'War Journalism, biased in favour of war.' I argue instead that the opposite of Peace Journalism is good journalism. Much of this Peace Journalism argument is derived from the work of Johan Galtung, who accuses 'war journalists' of reporting war in an enclosed space and time, with no context, concealing peace initiatives and making wars 'opaque/secret.' Galtung specifically calls on journalists as part of their mission to search out peace proposals which might begin as something small and beneath notice, but which might then be picked up and owned by politicians as their own. My response is clear and simple: creating peacemaking politicians is not the business of a reporter. I examine the traditional journalistic methods of using objectivity to get at a version of the truth. I concede that perfect truth is unattainable, (and paradoxically the tool of objectivity we use to get there is slippery too. I conclude that a more quotidian truth, or 'truthfulness' is though a manageable goal. I engage with philosophers who examine objectivity, concluding with the assistance of Thomas Nagel that it does still have a value. Nagel's account also has the merit of explaining how practices such as peace-reporting are bound to be less objective than alternatives, 'since they commit themselves to the adoption of particular perspectives, in effect giving up on the ideal of stripping away as much…as possible.' I examine the responses of the so-called 'journalism of attachment' framed as a desire of journalists faced by the horrors of Bosnia to cast off impartiality and emotional detachment and take

    Journal clubs provide a way to communicate advances in recent literature. In outpatient surgical subspecialties, such as dermatologic surgery, physicians may face challenges in finding or attending meetings pertinent to their practice. To assess the utility of a live web-based journal club in dermatologic surgery. Monthly 30-minute journal club sessions covering 5 to 6 scholarly articles. Anonymous surveys were used to evaluate the utility and self-reported learning associated with each meeting. From December 2012 to February 2015, 117 articles were reviewed. Survey data were acquired monthly, apart from 5 months of missing data. On average, the survey response rate was 37% (range: 7%-82%), with an average of 17 participants per monthly session (range: 9-25). The mean monthly usefulness score was 83.7 (101-point scale), with participants scoring their likelihood of returning in the future as 96.2 (0 = not likely, 100 = extremely likely). At each session, a mean of 68% of participants felt that at least one article would change their practice of medicine. A monthly online and telephonic journal club may be a practical and effective way to inform dermatologic surgeons of new developments in high impact literature and may influence improvements in individual practice.

  9. What are Journals for?

    Rallison, S P

    2015-03-01

    'The secret is comprised in three words - work, finish, publish.' Michael Faraday There are many reasons doctors want to publish their work. For most at an early stage in their career, this may be to add a line to their curriculum vitae and advance their careers but for academics, publishing is an expectation. Many will believe they have something important to say, and wish to provoke debate and discussion; others wish to share knowledge and experiences, which in medicine can lead to a satisfying change in clinical practice. All serve to register one's idea and educate others. However, for some, the reason is as basic as money. As we celebrate the 350th anniversary of the first academic publication, perhaps we have come full circle when it comes to why people publish? Publishing is a flourishing business. There were approximately 28,100 active scholarly peer-reviewed journals in mid-2012, collectively publishing about 1.8-1.9 million articles per year. The number of articles published each year and the number of journals have both grown steadily for more than two centuries, by about 3% and 3.5% per year respectively. (1) Journals have a responsibility to refine and define information and act as a scientific filter. Many of us will receive daily invitations in our email inbox from eclectic and new journals that are likely to take anything - is the filter now too porous? But this industry is like any other commercial activity and the supply still far outstrips the demand. Perhaps the internet revolution has merely fuelled our hunger to publish more? The launch of this exciting and innovative series about publishing coincides with the 350th celebration of the publication of the first academic journal. In the age of social media, the first question is 'What are journals for?', which Simon Rallison sets out to answer. Simon is Director of Publications at the Physiological Society, and was previously a journal publisher with Earthscan, Springer and Blackwell. Writing is

    A survey on the scientific journals dealing with microbiology published in Europe has been carried out. Eighteen European countries publish microbiological journals with the United Kingdom. Netherlands and Germany leading in number of journals on this specialty. Most of the European journals on microbiology are published bimonthly (27%), and English is the most common language used (54%). Most of these journals (86%) are included in some database, but only 36 (25%) are indexed in the six databases studied. Out of the 146 journals registered, 71 (49%), published in 11 European countries, are included in the 1995 Journal Citation Reports (ISI, Philadelphia).

  7. Rotordynamic Evaluation of Full Scale Rotor on Tilting Pad Bearings with 0.1 and 0.3 Preload

    Directory of Open Access Journals (Sweden)

    Weimin Wang

    2014-01-01

    Full Text Available A system identification method for rotating machinery stability evaluation is investigated based on sine sweep excitation testing with electromagnetic actuator. The traditional MIMO FRF is transformed into dFRF from real number field to complex field with a transformation matrix, eliminating the influence of forward and backward modal overlap and providing higher accuracy to identify rotor’s first forward modal parameters using the rational polynomial method. The modal parameters are acquired for stability estimation. Furthermore, two sets of bearing with preloads of 0.1 and 0.3 under both load-on-pad (LOP and load-between-pad (LBP conditions are investigated. The effects of oil inlet pressure (1.0 bar–1.75 bar and temperature (43°C–51°C on the stability of rotor are investigated in detail. Results indicate that the stability of rotor will be improved by increasing the oil inlet temperature and pressure. It is found that the rotor is more stable on bearing with 0.1 preload than that of 0.3 preload. Load-on-pad provides more damping to rotor than load-between-pad. The method and outcomes of this paper can provide both theory basis and technology foundation for improving the rotor stability of centrifugal compressors.

    Cadet de Gassicourt wrote a brief Eloge of Fourcroy in January 1810 as he died in December of 1809. Fourcroy had a major role concerning the new ideas on the place of pharmacy at the beginning of the 19th century. Fourcroy has had a key influence for the start of several pharmaceutical journals that wanted to emphasize the link between the new chemistry and pharmacy. None of these journals created with him will survive and one has to wait for 1909 to see the creation, without Fourcroy, of a new pharmaceutical journal, the "Journal de Pharmacie" that will become "Journal de Pharmacie et des Sciences accessoires", then "Journal de Pharmacie et de Chimie", before taking the name of"Annales Pharmaceutiques Françaises", the present official journal of the French Academy of Pharmacy. In spite of the essential role of Fourcroy at the start of pharmaceutical journals, Cadet did not even mention it in his Eloge of 1810.

  7. How to Rank Journals.

    Science.gov (United States)

    Bradshaw, Corey J A; Brook, Barry W

    2016-01-01

    There are now many methods available to assess the relative citation performance of peer-reviewed journals. Regardless of their individual faults and advantages, citation-based metrics are used by researchers to maximize the citation potential of their articles, and by employers to rank academic track records. The absolute value of any particular index is arguably meaningless unless compared to other journals, and different metrics result in divergent rankings. To provide a simple yet more objective way to rank journals within and among disciplines, we developed a κ-resampled composite journal rank incorporating five popular citation indices: Impact Factor, Immediacy Index, Source-Normalized Impact Per Paper, SCImago Journal Rank and Google 5-year h-index; this approach provides an index of relative rank uncertainty. We applied the approach to six sample sets of scientific journals from Ecology (n = 100 journals), Medicine (n = 100), Multidisciplinary (n = 50); Ecology + Multidisciplinary (n = 25), Obstetrics & Gynaecology (n = 25) and Marine Biology & Fisheries (n = 25). We then cross-compared the κ-resampled ranking for the Ecology + Multidisciplinary journal set to the results of a survey of 188 publishing ecologists who were asked to rank the same journals, and found a 0.68-0.84 Spearman's ρ correlation between the two rankings datasets. Our composite index approach therefore approximates relative journal reputation, at least for that discipline. Agglomerative and divisive clustering and multi-dimensional scaling techniques applied to the Ecology + Multidisciplinary journal set identified specific clusters of similarly ranked journals, with only Nature & Science separating out from the others. When comparing a selection of journals within or among disciplines, we recommend collecting multiple citation-based metrics for a sample of relevant and realistic journals to calculate the composite rankings and their relative uncertainty windows.

    2009-01-01

    This comparative study of journalism practices in Australia and Denmark explores the interplay between two concepts relevant for journalism's meaning-making activity: a curiosity seen as an action meant to close an information gap, and a story telling frame seen as a form of structuring information...... the epistemological and organisational dimension of frames relates to the process of  meaning-making. We suggest refining the concept of frame in journalism studies by making a distinction between a frame (an epistemological category) and an angle (a textual organisation category). Our investigation shows...... that this distinction better serves the analysis and understanding of the mechanisms behind journalism in comparative contexts. Udgivelsesdato: December...

  13. Variable Parameters PD Control and Stability of a High Rate Rigid Rotor-Journal Active Magnetic Bearing System

    Institute of Scientific and Technical Information of China (English)

    LUO Kai

    2005-01-01

    Stability is a key problem that means whether a high rate rotor-active magnetic bearings system works reliably or not. Aiming at a bearings system described with nonlinear equations, this paper built a linear model according to the system behavior. Considering realization of the control system and behavior of a high rate rotor system (magnetic force is far smaller than input force produced by mass eccentricity) this paper proposes a design method of variable parameters PD control algorithm that can be used universally. The control system was simplified and a mass of adjusting work of control parameters was reduced. Analysis and simulation indicated that the bearings system could get a wider stable region of harmonic motion, and proved that the algorithm is robust and advanced. The control system can be realized because the winding electric currents are positive. The method is convenient for operation and can easily be used for engineering practice.

The purpose of this case study article was to describe the case of phishing and suggest the measures to prevent it. In June 29, 2016, informant submitted his manuscript to phishing e-mail jeet@jeet.us, because he misunderstood the phishing site as that of JEET. After that he received the confirmation mail of acceptance and expected date of publication. However, there was no further progress, he inquired official e-mail of JEET on his manuscript. During the correspondence with journal secretary, he found that it was the phishing. There was no request of publication fee from phisher. It is difficult to know what is the purpose of this phishing. Probably, it may be an initial inducement to deceive the contributor. If the manuscript is published in the phishing web site, phisher may be able to request publication fee as next fraudulent action. Besides of announcement of precaution on phishing, regrettably there is no way to punish phishers or more active protective action. It was not possible to ask the investigation of the case to police because there was no monetary loss. Also it was impossible to shut down the phishing web site http://www.jeet.us because server was located in the United States. The international cooperation, enactment of international law on phishing, and its enforcement is necessary to eradicate this kind of criminal action.

Understanding the characteristics and how they operate could help us avoid publishing our work in scam journals. These journals claim (falsely that they employ a blind review process by experts in the field, promise quick turnaround, claim legitimacy by quoting the ISSN and listing a number of databases in which they are indexed (e.g., EBSCO, DOAJ and PROQUEST. The paper outlines 15 reasons why as members of the academic community we should shun journals of dubious quality. The key message of this paper is that before we send our scholarly work to academic journals, we need to invest time doing our due diligence, making sure that our target journal is a legitimate and respectable outlet for our work.

    Aske Kammer

    2014-06-01

    Full Text Available Proposing an explanation of current macro-sociological changes and institutional transformations in journalism, this article argues that journalism is currently undergoing a process of mediatization. Drawing upon the international research literature as well as statements from interviews with news workers working on Danish news websites, the article examines four current trends in journalism that are closely connected to the rise of news on the web, namely the use of the affordances of news websites, radical commercialization, increased audience participation in news production, and the increased multi-skilling and simultaneous de-skilling of journalists. Taken together, these trends reflect a process through which journalism increasingly subsumes itself to the logic of the media, suggesting mediatization as an adequate explanatory framework. One implication of such a process is that journalism seems to be transforming from an occupational profession into an organizational one.

  17. Our Censored Journals

    Directory of Open Access Journals (Sweden)

    David Healy

    2008-01-01

    Full Text Available When an article is rejected by a medical journal, the standard assumption is that the article is unsound or there is something wrong with the author. Alternatively, it may have been because the journal editor was concerned about the consequences should the article be published. This article seeks to inform discussion by providing a series of instances in which editorial concerns about the consequences to journals may have counted for more than any assessment about the truth-value of the article or the motives of its authors. This claim is based on the fact that different journals may treat exactly the same article in an entirely different fashion; some issues appear to be taboo in certain journals, no matter who the author, and there is a series of explicit communications from editors that publication has been held up by their legal departments.

  18. Rethinking Journalism Again

    DEFF Research Database (Denmark)

    It’s easy to make a rhetorical case for the value of journalism. Because, it is a necessary precondition for democracy; it speaks to the people and for the people; it informs citizens and enables them to make rational decisions; it functions as their watchdog on government and other powers that be....... But does rehashing such familiar rationales bring journalism studies forward? Does it contribute to ongoing discussions surrounding journalism’s viability going forth? For all their seeming self-evidence, this book considers what bearing these old platitudes have in the new digital era. It asks whether...... such hopeful talk really reflects the concrete roles journalism now performs for people in their everyday lives. In essence, it poses questions that strike at the core of the idea of journalism itself. Is there a singular journalism that has one well-defined role in society? Is its public mandate as strong...

The shift from an analog to digital workflow introduces computation as a central component of news production.

To journalism, computerization is a promising path for news production, particularly for ...

  7. War Journalism and 'Objectivity'

    Directory of Open Access Journals (Sweden)

    Annabel McGoldrick

    2006-10-01

    Full Text Available This article opens by considering an apparent paradox. Many professional journalists, working on many media in many countries, consider themselves 'objective'. They do not, at least, set out to skew their coverage of important issues in favour of one side or the other. And yet much of their coverage of conflicts shows a discernible dominant pattern of War Journalism - biased in favour of war. This is not because of a lack of objectivity, the article suggests, but a surfeit. The set of conventions many editors and reporters regard as defining 'objective' journalism arose in response to economic and political conditions which rewarded news that could commend itself as unobjectionable to the maximum number of potential customers. Three of the most important conventions privilege official sources; a dualistic construction of stories and event, over process. Each of these, when applied to the representation of conflicts, leads readers and audiences - or leaves them - to over-value violent, reactive responses and under-value non-violent, developmental responses. Industry conventions sit uneasily alongside equally time-honoured expectations of journalism. These are encoded in rules and regulations governing the content of broadcast news, in many jurisdictions which have a public service concept for radio and television. In some respects, War Journalism can be shown to make it more difficult for broadcast news services to fulfil their public service obligations. Awareness is now growing, of the tension between these two pressures on journalism and its influence on the way pressing public debates are shaped and mediated. More Peace Journalism would help to bring public service news back into line with legitimate public expectations.

  9. Korean association of medical journal editors at the forefront of improving the quality and indexing chances of its member journals.

    Science.gov (United States)

    Suh, Chang-Ok; Oh, Se Jeong; Hong, Sung-Tae

    2013-05-01

    The article overviews some achievements and problems of Korean medical journals published in the highly competitive journal environment. Activities of Korean Association of Medical Journal Editors (KAMJE) are viewed as instrumental for improving the quality of Korean articles, indexing large number of local journals in prestigious bibliographic databases and launching new abstract and citation tracking databases or platforms (eg KoreaMed, KoreaMed Synapse, the Western Pacific Regional Index Medicus [WPRIM]). KAMJE encourages its member journals to upgrade science editing standards and to legitimately increase citation rates, primarily by publishing more great articles with global influence. Experience gained by KAMJE and problems faced by Korean editors may have global implications.

  15. Dissertation to Journal Article: A Systematic Approach

    Directory of Open Access Journals (Sweden)

    Brychan Thomas

    2012-01-01

    Full Text Available The aim of the paper is to elucidate a systematic approach to convert a Masters dissertation into a journal article. This approach has involved a fundamental thematic review of the literature concerning the conversion of dissertations into journal articles. From these sources pertinent approaches, processes, lessons, and guidance have been noted and analysed. By undertaking this distillation of relevant material, to enable the efficient conversion of dissertations into journal articles, appropriate procedures and conclusions have been compiled. Findings present current thinking on the conversion of a dissertation into a journal paper in terms of how dissertations differ from journal articles, reframing for publication, rethinking the material, trimming the length, time taken to rewrite the material, specific lessons, and adapting for publication. Recommendations provided in the paper will enable staff to take this course of action when developing their publication portfolio to become more research active and to make an important contribution to the publication output of their department/school/faculty, especially with regard to assessment exercises such as the Research Excellence Framework. The value of the paper is that by following appropriate approaches, processes, and procedures it is possible to convert a good dissertation into a ranked journal article.

  18. Three journal similarity metrics and their application to biomedical journals.

    Science.gov (United States)

    D'Souza, Jennifer L; Smalheiser, Neil R

    2014-01-01

    In the present paper, we have created several novel journal similarity metrics. The MeSH odds ratio measures the topical similarity of any pair of journals, based on the major MeSH headings assigned to articles in MEDLINE. The second metric employed the 2009 Author-ity author name disambiguation dataset as a gold standard for estimating the author odds ratio. This gives a straightforward, intuitive answer to the question: Given two articles in PubMed that share the same author name (lastname, first initial), how does knowing only the identity of the journals (in which the articles were published) predict the relative likelihood that they are written by the same person vs. different persons? The article pair odds ratio detects the tendency of authors to publish repeatedly in the same journal, as well as in specific pairs of journals. The metrics can be applied not only to estimate the similarity of a pair of journals, but to provide novel profiles of individual journals as well. For example, for each journal, one can define the MeSH cloud as the number of other journals that are topically more similar to it than expected by chance, and the author cloud as the number of other journals that share more authors than expected by chance. These metrics for journal pairs and individual journals have been provided in the form of public datasets that can be readily studied and utilized by others.

Most of them worked in stable media industries that, thanks largely to a lucrative advertising-based revenue model, had been highly profitable for decades if not centuries, and they had something close to a monopoly on providin...

    Full Text Available It is quite impressive the visibility of online publishing compared to offline. Lawrence (2001 computed the percentage increase across 1,494 venues containing at least five offline and five online articles. Results shown an average of 336% more citations to online articles compared to offline articles published in the same venue. If articles published in the same venue are of similar quality, then they concluded that online articles are more highly cited because of their easier access. Thomson Scientific, traditionally concerned with printed journals, announced on November 28, 2005, the launch of Web Citation Index™, the multidisciplinary citation index of scholarly content from institutional and subject-based repositories (http://scientific.thomson. com/press/2005/8298416/. The Web Citation Index from the abstracting and indexing (A&I connects together pre-print articles, institutional repositories and open access (OA journals (Chillingworth, 2005. Basically all research funds are government granted funds, tax payer’s supported and therefore, results should be made freely available to the community. Free online availability facilitates access to research findings, maximizes interaction among research groups, and optimizes efforts and research funds efficiency. Therefore, Ambi-Água is committed to provide free access to its articles. An important aspect of Ambi-Água is the publication and management system of this journal.

  19. "Space of physics journals": in search of journals of quality

    CERN Document Server

    Katchanov, Yurij L

    2016-01-01

    This paper analyses the problem of scientific quality of physics journals. The main assumption is that the quality of a physics journal exists only in reference to other journals. Instead of constructing new indicators of scientific quality, we identify a physical journal with corresponding empirical distribution function of citations. From our relational point of view, the space of physics journals is only a system of differences between empirical distribution functions of citations. Using data from Web of Science Core Collection we consider the space of physics journals and the space of scientific publishers. The first provides an objective basis for the grouping of physics journals on the basis of a whole range of indicators (citation statistics, country, publisher, etc.). The second reveals the "competitors' triangle" of regional publishers, transnational publishers and professional physical societies. These findings have prompted us to advance the hypothesis that the structure of the space of physics jou...

    The Handbook of Journal Publishing is a comprehensive reference work written by experienced professionals, covering all aspects of journal publishing, both online and in print. Journals are crucial to scholarly communication, but changes in recent years in the way journals are produced, financed, and used make this an especially turbulent and challenging time for journal publishers - and for authors, readers, and librarians. The Handbook offers a thorough guide to the journal publishing process, from editing and production through marketing, sales, and fulfilment, with chapters on management, finances, metrics, copyright, and ethical issues. It provides a wealth of practical tools, including checklists, sample documents, worked examples, alternative scenarios, and extensive lists of resources, which readers can use in their day-to-day work. Between them, the authors have been involved in every aspect of journal publishing over several decades and bring to the text their experience working for a wide range of ...

  9. A profession termed Journalism

    Directory of Open Access Journals (Sweden)

    Manuel Fernández Areal, Ph. D.

    2010-01-01

    Full Text Available New technologies can foster the impression that journalism, as a profession will become extinct probably in a short term. Anybody can have access to any information sources as well as to transmit – through Internet- all sorts of messages at an unusual speed, and this fact seems to support the idea that no technical training will be needed in the future not even an specific cultural background will be required, much less an university degree or qualification that ensures a responsible and appropriate practice of the modern social communication. The Federation of Journalists Associations in Spain (FAPE in its Draft of the Professional Statute is in favor of a graduated or qualified profession at an university level, and its Commission for Complaints has been developing a successful work regarding the professional self-regulation and self-control for the benefit of society. Therefore, there are good reasons for being optimist. Journalism, as a profession, is not going to disappear, and maybe it is time to consider it, really, as an academic qualified profession.

  10. [The future of electronic biomedical journals].

    Science.gov (United States)

    Maisonneuve, Hervé; Schnitter, Claude

    2009-10-01

    Old journals are using information technologies by putting production pdfs on line and applying several useful functions, such as search engines or podcasts. Journals have rapidly taken up the Electronic Long Paper Short (ELPS) trend, publishing abridged articles in the physical journal and longer versions on their websites, with electronic supplements (supplementary references, spreadsheets, videos, etc.). Journals with no paper version have been created that use all the functionalities of the Internet and now of web 2.0. They are numerous (PLoS, BioMed Primary, etc..) and are acquiring a reputation. Free access for all, information for all in 2015, are some interesting objectives that remain to be funded. The economic model of these exclusively electronic journals is uncertain, although some are funded by authors (and not at all by readers) or institutions. Spotless research is a rare exception, but few stakeholders are taking an active interest in it. Humans, much more than the tool or the media, are at the heart of the system. We must remember that those who have wanted to predict the future have always been wrong.

And how will we continue practicing it into the coming era? on this article I would like to think through some of the most important challenges facing the study of contemporary journalism. I’ll be drawing from my own work that has been somewhat focused on the fundamental question of what journalism is for.

  2. Style in medical journals.

    Science.gov (United States)

    Adams Smith, D E

    1983-10-15

    A study of medical journals from 1962 showed a constant preoccupation with style. Editors and contributors on both sides of the Atlantic revile unnecessary obscurity and complexity and the use of jargon, barbarisms, vogue words, and weak impersonal constructions. They bewail the pompous use of verbiage and the "medspeak" typified by acronyms and neologisms created by affixation. Suggestions for possible causes of poor medical style range from editorial demands for compression and a general ignorance of the principles of good writing to faulty logic and the subordination of communication to status seeking. The consequences of bad writing may include the fragmentation of knowledge, an increase in the importance of abstracting services, a trend towards free glossy medical newspapers, and, as remedial measures, workshops and courses in medical writing. Some implications for English language teachers working with foreign medical graduates and preclinical students are discussed.

  3. Innovation Journalism: A Multiple Concept

    Directory of Open Access Journals (Sweden)

    Ana Marta Moreira Flores

    2017-08-01

    Full Text Available Thinking about the journalistic activity beyond its traditional forms is a recurrent practice in contemporary journalism. The plurality of audiences, behaviors and technologies challenge the classic models of journalism in a way that encourages innovation in different aspects of the activity. However, the term innovation is being broadly applied without rigorous and interesting delimitation to the academic environment. In this sense, we propose in this article initial directions under which aspects it is possible to understand the journalism innovation. It starts from the original concept in the field of Economics and Management to expand its meaning to the Social Sciences and Journalism. We expose three instances in which contemporary journalism already has changes, to understand the journalism as a process and product, which are: 1 content and narrative, 2 technology and format and 3 business model. In addition to this segmentation, some initiatives are presented to illustrate each sub-category and to design an updated concept about innovation journalism. Pensar a atividade jornalística para além de suas formas tradicionais é uma prática já recorrente no jornalismo contemporâneo. A pluralidade de públicos, comportamentos e tecnologias desafiam os modelos clássicos do jornalismo em um movimento que incentiva a inovação em diferentes aspectos da atividade. No entanto, o termo inovação vem sendo aplicado de forma ampla sem um rigor e delimitação interessantes para a pesquisa em jornalismo. Nesse sentido, propomos no presente artigo direcionamentos iniciais sob quais aspectos podemos compreender o jornalismo de inovação. Partimos da origem do conceito na área da Economia e Administração para ampliar seu sentido nas Ciências Sociais e no próprio Jornalismo como atividade. Expomos três instâncias das quais o jornalismo contemporâneo já apresenta novidades para entender o jornalismo de inovação como processo e produto

    Irfan Ullah

    2014-12-01

    Full Text Available I am delighted to welcome you to a newly launched Solarlits electronic journal: the Journal of Daylighting (JD. As the Editor-in-Chief of JD it is a great pleasure to introduce the inaugural issue of this new, open-access, bi-annual journal to readers, researchers, future authors, and colleagues. The decision by SolarLits to launch this new journal is very timely. Because the growth of lighting demand is increasing due to rising average illuminance levels in buildings, more attention has been paid to introduce daylighting in buildings, which will sustainably reduce the overall energy consumption in buildings. JD will serve as a new international platform for researchers to share advances in daylighting. As an international, peer-reviewed research journal it will exclusively cover the vibrant and diverse field of daylighting technologies and applications. JD will serve as an interdisciplinary forum for the scientific and research community active in daylighting and its applications. Topics will include, but not limited to: daylighting and hybrid lighting systems, lighting and daylighting simulation, lighting designs, lighting metrology and light quality, lighting control, building physics - lighting, building energy modeling, energy efficient buildings, zero-energy buildings, indoor environment quality, sustainable solar energy systems, application of solar energy sources in buildings, building-integrated photovoltaics, and solar thermal and concentrator technology. I will work with the Associate Editors, the Editorial Board, and the scientific and engineering research community to make JD a primary journal for the dissemination of breakthrough results, discussion of key challenges, and topics in daylighting. JD will publish full-length research articles, review articles, book reviews, and short communications.

    Full Text Available Objectives: To perform an extensive analysis of journals in Medicine III - CAPES, and specifically those in the areas of Otorhinolaryngology, Orthopedics and Traumatology and Chest Surgery. Method: An active search for the impact factors in the Journal Citation Reports, Scimago, their indexation in Scielo, Lilacs, Scopus and Google Scholar, and their stratification in WebQualis was done. Results: Forty-four journals with measured impact factors ranging from 3.006 to 0.128 were detected in the area of Otorhinolaryngology; however, only 26 of them (60% had a Qualis measured by CAPES; in the stratification, no journal was detected in A1, three were A2 and nine B1. Three journals were located for Chest Surgery, with only one of them having a measured Qualis (A2 with a mean of 3.61. Sixty-seven journals were detected for Orthopedics and Traumatology, with an impact factor ranging from 4.699 to 0.156; Qualis was measured in only 38 of them (60%; there were three journal stratified as A1, seven as A2 and 25 as B1. Conclusion: The search for journals of higher impact induces authors to not publish in journals related to their area and facing more difficulties than investigators from other areas.

  11. Situating peace journalism in journalism studies: A critical appraisal

    Directory of Open Access Journals (Sweden)

    Thomas Hanitzsch

    2007-10-01

    Full Text Available Most wars were not brought to our attention if there were no journalists to report on them and no news media to send reporters to conflict spots. At the same time, the media often give priority to conflict and war at the expense of playing a positive role in attempts to bring about peace. The concept of peace journalism is, therefore, seen as an alternative model to traditional ways of war reporting. This article argues, however, that the idea of peace journalism comes as old wine in new bottles. Although carrying a noble goal, it ignores the manifold nuances in the media and tends to highlight the exceptional, spectacular and negative of war coverage. The idea of peace journalism tends to overestimate the influence journalists and the media have on political decisions; and it often understands audiences in terms of a passive mass that needs to be enlightened by virtue of peace reporting. In addition to this, peace journalism is, to a considerable extent, based on an overly individualistic perspective and ignores the many structural constraints that shape and limit the work of journalists: few personnel, time and material resources; editorial procedures and hierarchies; textual constraints; availability of sources; access to the scene and information in general - just to name a few. All this suggests that the conduct of peace journalism is not a matter of individual leeway, and media structures and professional routines cannot be modified from the position of the individual journalist. Modern corporate journalism involves processes of organized news production, thus giving priority to organizational and institutional factors as well as processes of professional socialization. To have any impact on the way the news is made, and its critical scrutiny, the advocates of peace journalism must address the structural constraints of news production. The discussion of peace journalism, and particularly of its practical implications, must be tied to the

  13. Medical Journalism and Emergency Medicine

    Directory of Open Access Journals (Sweden)

    Saeed Safari

    2015-07-01

    Full Text Available Nowadays, many researches in the field of medicine are conducting all around the world and medical journalism is a way to share the results. In fact, dissemination of the related manuscripts can prevent the repetitive research or may even lead to conducting a better survey. Therefore high quality medical journals are considered as up-to-date resources for further investigations. Medical journals are propagating their papers in various media including television programs, newspapers, internet websites and different social media. So they can influence the government policy makers, health-care professionals and even public. Moreover, most researchers hear about medical discoveries for the first time through medical journals and their related social media. So as well a high quality journal can help to improve medical science, a journal of poor quality can be damaging and distorting. Indeed, popular journals have the power of inventing a “communication storm” to draw attention to a certain topic. Thus they have to respect the accepted international principles to prevent spreading inaccurate and misleading data. This paper aims to review the previous and current situation of medical journalism by focus on field of emergency medicine.

    2017-03-01

    At a time of fake news, hacks, leaks, and unverified reports, many people are unsure whom to believe. How can we communicate in ways that make individuals question their assumptions and learn? My colleagues at The Hastings Center and many journalists and scientists are grappling with this question and have, independently, reached the same first step: recognize that facts can't be fully understood without probing their connection to values. "Explaining the basics is important, of course, but we also need to diversify our approach to the coverage of science-particularly as it intersects with the matrix of cultural, religious, social, and political values of our readers," said an article in Undark, an online magazine of science journalism. An editorial in Nature called for scientists to engage directly with citizens in debates over climate change and genome editing, noting that "the ethical issues can be critically dependent on the science, for example, in understanding where the boundaries between non-heritable and heritable genome modifications might be."

    Palla, Gergely; Mones, Enys; Pollner, Péter; Vicsek, Tamás

    2015-01-01

    Scientific journals are the repositories of the gradually accumulating knowledge of mankind about the world surrounding us. Just as our knowledge is organised into classes ranging from major disciplines, subjects and fields to increasingly specific topics, journals can also be categorised into groups using various metrics. In addition to the set of topics characteristic for a journal, they can also be ranked regarding their relevance from the point of overall influence. One widespread measure is impact factor, but in the present paper we intend to reconstruct a much more detailed description by studying the hierarchical relations between the journals based on citation data. We use a measure related to the notion of m-reaching centrality and find a network which shows the level of influence of a journal from the point of the direction and efficiency with which information spreads through the network. We can also obtain an alternative network using a suitably modified nested hierarchy extraction method applied ...

    We analysed the authorship policies of a random sample of 600 journals from the Journal Citation Reports database. 62.5% of the journals we sampled had an authorship policy. Having an authorship policy was positively associated with impact factor. Journals from the biomedical sciences and social sciences/humanities were more likely to have an authorship policy than journals from the physical sciences, engineering or mathematical sciences. Among journals with a policy, the most frequent type of policy was guidance on criteria for authorship (99.7%); followed by guidance on acknowledgments (97.3%); requiring that authors make substantial contributions to the research (94.7%); requiring that authors be accountable for the research as a whole (84.8%); guidance on changes in authorship (77.9%); requiring that authors give final approval to the manuscript (77.6%); requiring that authors draft or critically revise the manuscript (71.7%); providing guidance on corporate authorship (58.9%); prohibiting gift, guest or ghost authorship (31.7%); requiring authors to describe their contributions (5.3%); limiting the number of authors for some types of articles (4.0%) and requiring authors to be accountable for their part in the research (1.1%). None of the policies addressed equal contribution statements. Journals that do not have authorship policies should consider adopting or developing ones.

  14. Literary journalism : the intersection of literature and journalism

    Directory of Open Access Journals (Sweden)

    Sonja Merljak Zdovc

    2004-12-01

    Full Text Available Literary journalism is a style of newspaper and magazine writing that developed as a reaction against facto graphic and objective journalism. Rather than answering the informational who, what, when, or where, it depicts moments in time. It has also managed to eschew the formula of newspaper feature writing, with its predictability and cliches. Instead, it appointed the techniques of realistic  fiction to portray daily life. The author of this paper attempts to present the genre that belongs at the same time to literature and journalism; it combines the best of both practices in order to give the reader the most vivid and accurate picture of society. The author of this paper also attempts to present literary journalism as it exists in Slovenia.

    It is a privilege to be Editor-in-Chief of Journal of Optics at this exciting time when the use of light spearheads the development of new technologies in telecommunications, green energy, manufacturing, medicine and defence, just to mention a few. These technological advances, seen by many as the next photonic technological revolution, are underpinned by fundamental and applied research in the following key directions: Nanophotonics and plasmonics Metamaterials and structured photonic materials Nonlinear and ultrafast optics Photonics at the life science interface Information and communication optics Integrated optics systems and devices Material processing with light Propagation, diffraction and scattering This is where Journal of Optics focuses its attention. This editorial marks the first issue of the journal published under the abbreviated name (shortened from Journal of Optics A: Pure and Applied Optics). The name change is just one of a series of changes introduced in the last year, along with the 8 subject sections listed above and the appointment of Section Editors. With the name change, we will also update the look of the journal by introducing colour cover images which will feature some of the most exciting research in the journal. We have retained many of the journal's original selling points: we are found in thousands of libraries around the world, and will continue our policy of free web access to all papers for 30 days after publication, ensuring broad and unrestricted dissemination of your research results. We will also continue our strong and well respected special issue and topical review programmes and we are always grateful to receive new suggestions for special issues or review articles. Along with the Editorial Board, I would like to thank the authors, referees and readers who have contributed to the success of Journal of Optics.

    Full Text Available Journal writing can be a creative adjunct to psychotherapy. This article will describe a qualitative study of the experiences of journal writers. Each participant’s narrative illustrates the integration of Winnicott’s transitional phenomena, Freeman’s four stages of epiphanies, and Kegan’s adult developmental stages through journal writing. The central findings of this research are that the experience of the participants can be identified in the following three categories: therapeutic experience,meditative experience, and a transformative experience. Journal writing can be adapted by psychotherapists, as an adjunct to therapy, to aid clients in elaborating their stories, listening within, identifying epiphanies, and moving forward in the change process.This article will present a case study of one of the narratives from this research.

  9. Peace Journalism and its discontents

    Directory of Open Access Journals (Sweden)

    Jake Lynch

    2007-10-01

    Full Text Available This article is a response to criticisms of peace journalism from a journalist (David Loyn and a scholar (Thomas Hanitzsch by one who has recently gone from one profession to the other. It argues that journalists, like Loyn, often misrepresent the dividing lines in the debate over peace journalism because they take an unduly realist view of news and its relationship with the facts. This is tantamount to ignoring some of the most important insights of research into journalism and communications. On the other hand, scholars like Hanitzsch take an unduly conventionalist view, it argues, thereby excluding important arguments about the basis upon which we should prefer some representations of conflict over others, as being more accurate and more useful. Peace journalism bases its claims on observations about conflict, peace and violence by researchers in Peace and Conflict Studies, preferable as a basis for representing conflict to the often-unexamined conventions of the news industry. Peace journalism is also criticised as resting on an overly individualistic model of journalistic endeavour, attaching too little weight to the importance of structural constraints on the work of editors and reporters. This article acknowledges those constraints as governing, though not fully determining influences; but it also argues that peace journalism can contribute to the mobilization of social resources for structural reform, or for the existing structural provisions for public service concepts in journalism to be applied and carried out. Furthermore, some research into journalistic representations of conflict is insufficiently attentive to the insights of peace research, as distinct from research on journalism, a shortcoming which, the article says, invalidates some of its conclusions.

  15. Global Journalism Ethics: Widening the Conceptual Base

    Directory of Open Access Journals (Sweden)

    Stephen J. A. Ward

    2008-01-01

    Full Text Available For most of its history, journalism ethics has been highly practical in aim, in theorizing, and in application. Inquiry analyzed what was occurring inside newsrooms and its scope was parochial. Starting from the premise that a parochial approach no longer serves journalism, the study of journalism, or the public of journalism, in this paper it is argued that a major task of journalism ethics is to construct a more non-parochial ethics—a global journalism ethics informed by critical work from various disciplines and cultures. The discussion presented charts the trajectory of journalism ethics over several centuries to explain the role of parochialism and the limits of theorizing in journalism ethics. This historical perspective also serves as a foundation for outlining what a future journalism ethics might look like, if we widen the conceptual base by incorporating new knowledge of media from outside journalism ethics, and by redefining journalism ethics as a global enterprise.

  18. For 481 biomedical open access journals, articles are not searchable in the Directory of Open Access Journals nor in conventional biomedical databases.

    Science.gov (United States)

    Liljekvist, Mads Svane; Andresen, Kristoffer; Pommergaard, Hans-Christian; Rosenberg, Jacob

    2015-01-01

    Background. Open access (OA) journals allows access to research papers free of charge to the reader. Traditionally, biomedical researchers use databases like MEDLINE and EMBASE to discover new advances. However, biomedical OA journals might not fulfill such databases' criteria, hindering dissemination. The Directory of Open Access Journals (DOAJ) is a database exclusively listing OA journals. The aim of this study was to investigate DOAJ's coverage of biomedical OA journals compared with the conventional biomedical databases. Methods. Information on all journals listed in four conventional biomedical databases (MEDLINE, PubMed Central, EMBASE and SCOPUS) and DOAJ were gathered. Journals were included if they were (1) actively publishing, (2) full OA, (3) prospectively indexed in one or more database, and (4) of biomedical subject. Impact factor and journal language were also collected. DOAJ was compared with conventional databases regarding the proportion of journals covered, along with their impact factor and publishing language. The proportion of journals with articles indexed by DOAJ was determined. Results. In total, 3,236 biomedical OA journals were included in the study. Of the included journals, 86.7% were listed in DOAJ. Combined, the conventional biomedical databases listed 75.0% of the journals; 18.7% in MEDLINE; 36.5% in PubMed Central; 51.5% in SCOPUS and 50.6% in EMBASE. Of the journals in DOAJ, 88.7% published in English and 20.6% had received impact factor for 2012 compared with 93.5% and 26.0%, respectively, for journals in the conventional biomedical databases. A subset of 51.1% and 48.5% of the journals in DOAJ had articles indexed from 2012 and 2013, respectively. Of journals exclusively listed in DOAJ, one journal had received an impact factor for 2012, and 59.6% of the journals had no content from 2013 indexed in DOAJ. Conclusions. DOAJ is the most complete registry of biomedical OA journals compared with five conventional biomedical databases

  20. On the future contents of a small journal of histochemistry.

    Science.gov (United States)

    Pellicciari, C

    2012-12-10

    In the last three years, more than 70,000 scientific articles have been published in peer reviewed journals on the application of histochemistry in the biomedical field: most of them did not appear in strictly histochemical journals, but in others dealing with cell and molecular biology, medicine or biotechnology. This proves that histochemistry is still an active and innovative discipline with relevance in basic and applied biological research, but also demonstrates that especially the small histochemical Journals should likely reconsider their scopes and strategies to preserve their authorship. A review of the last three years volumes of the European Journal of Histochemistry, taken as an example of a long-time established small Journal, confirmed that the published articles were widely heterogeneous in their topics and experimental models, as in this Journal's tradition. This strongly suggests that a Journal of histochemistry should keep its role as a forum open to an audience as broad as possible, publishing papers on cell and tissue biology in a wide variety of models. This will improve knowledge of the basic mechanisms of development and differentiation, while helping to increase the number of potential authors since scientists who generally do not use histochemistry in their research will find hints for the applications of histochemical techniques to novel still unexplored subjects.

  1. Comparison of Traditional Versus Evidence-Based Journal Club Formats

    Directory of Open Access Journals (Sweden)

    Kathleen Packard, PharmD, MS, BCPS

    2011-01-01

    Full Text Available AbstractPurpose: The objective of the study was to compare a traditionally structured journal club with an evidence based structured journal club during an advanced clinical pharmacy rotation and to determine the best utilization that aligns with recent changes to the pharmacy school accreditation standards.Methods: The study included 21 students who completed journal club utilizing the traditional journal club format and 24 students who utilized an evidence based journal club format. Background characteristics, student reported beliefs, and mean critical evaluation skills scores were evaluated and compared in each group.Results: There were no statistically significant differences between the two cohorts in mean overall percentage grade for the activity. Students in the traditional cohort received significantly higher grades for the Study Analysis and Critique section (90.97 + 12.18 versus 81.25 + 11.18, P=0.01 as well as for the Preparedness section (96.11 + 8.03 versus 85.0 + 17.13, P=0.002. Students in the evidence based cohort received statistically superior grades for the Presentation Skills section (96.43 + 6.39 versus 82.47 + 14.12, P=0.0004.Conclusion: An evidence based journal club is a reasonable and effective alternative to the traditionally structured journal club when the primary objective is to assist students in understanding evidence based concepts and to apply current literature to clinical practice.

  2. Is journalism failing on climate?

    Science.gov (United States)

    Rahmstorf, Stefan

    2012-12-01

    How can we build a reliable and affordable energy supply based on renewables? How rapidly do we need to cut greenhouse gas emissions to keep climate change within manageable bounds? What does it take to maintain a stable common currency of different nations? These are just a few examples of questions that are critical for our future and that require an understanding of complex systems—the energy system, the climate system, the financial system. Finding sound answers to these questions requires sophisticated scientific analysis and expert knowledge; a lay person's intuition will clearly not suffice. Yet, decisions in a democracy are (and should be!) taken by politicians and the voting public who are not usually scientific experts. Hence the well-being of our societies—and even more so the living conditions of future generations, which are defined by the decisions we take today—depends on the wider public being well informed about the state of scientific knowledge and discourse. The media are the most important means by which lay people obtain their information about science. Good science journalism is therefore a decisive factor for the long-term success of modern society. Good science journalism clearly must be critical journalism, and it requires journalists who know what is what, who can put things into a perspective, and who are able to make well-informed judgements. After all, the role of science journalism is not simply to act as a 'translator' who conveys the findings of scientists in a language understandable to lay people. Rather, good science journalism will provide the public with a realistic impression of what is well established in science and what are current 'hot topics', uncertainties and controversies. It will also discuss the methods and social context of the scientific endeavour. There is ample evidence that in the area of climate science, journalism too often is failing to deliver this realistic picture to its audience, despite many good

  15. Narrative journalism as complementary inquiry

    Directory of Open Access Journals (Sweden)

    Jørgen Jeppesen

    2011-10-01

    Full Text Available Narrative journalism is a method to craft stories worth reading about real people. In this article, we explore the ability of that communicative power to produce insights complementary to those obtainable through traditional qualitative and quantitative research methods. With examples from a study of journalistic narrative as patient involvement in professional rehabilitation, interview data transcribed as stories are analyzed for qualities of heterogeneity, sensibility, transparency, and reflexivity. Building on sociological theories of thinking with stories, writing as inquiry, and public journalism as ethnography, we suggest that narrative journalism as a common practice might unfold dimensions of subjective otherness of the self. Aspiring to unite writing in both transparently confrontational and empathetically dialogic ways, the narrative journalistic method holds a potential to expose dynamics of power within the interview.

    Richards, Lorie Gage

    2015-01-01

    The American Journal of Occupational Therapy (AJOT) had a successful 2015. From September 2014 to September 2015, the number of manuscripts submitted had increased by 35%. Manuscripts were received from 23 countries, compared with 17 countries in 2014. AJOT continues to have the highest impact factor and to be the highest ranked of the occupational therapy journals listed in Journal Citation Reports. AJOT continues to focus on publishing research articles on aspects of occupational therapy among varied populations with diverse acute and chronic conditions. Additional changes for 2015 include new associate editors, a significantly enlarged pool of reviewers from across the globe, continuous publishing, pay-per-view, updated author guidelines, and the adoption of clinical trial registration requirements effective January 1, 2016.

  18. Can Scientific Journals be Classified in terms of Aggregated Journal-Journal Citation Relations using the Journal Citation Reports?

    CERN Document Server

    Leydesdorff, Loet

    2009-01-01

    The aggregated citation relations among journals included in the Science Citation Index provide us with a huge matrix which can be analyzed in various ways. Using principal component analysis or factor analysis, the factor scores can be used as indicators of the position of the cited journals in the citing dimensions of the database. Unrotated factor scores are exact, and the extraction of principal components can be made stepwise since the principal components are independent. Rotation may be needed for the designation, but in the rotated solution a model is assumed. This assumption can be legitimated on pragmatic or theoretical grounds. Since the resulting outcomes remain sensitive to the assumptions in the model, an unambiguous classification is no longer possible in this case. However, the factor-analytic solutions allow us to test classifications against the structures contained in the database. This will be demonstrated for the delineation of a set of biochemistry journals.

  19. The knowledge base of journalism

    DEFF Research Database (Denmark)

    Svith, Flemming

    In this paper I propose the knowledge base as a fruitful way to apprehend journalism. With the claim that the majority of practice is anchored in knowledge – understood as 9 categories of rationales, forms and levels – this knowledge base appears as a contextual look at journalists’ knowledge......, and place. As an analytical framework, the knowledge base is limited to understand the practice of newspaper journalists, but, conversely, the knowledge base encompasses more general beginnings through the inclusion of overall structural relationships in the media and journalism and general theories...... on practice and knowledge. As the result of an abductive reasoning is a theory proposal, there is a need for more deductive approaches to test the validity of this knowledge base claim. It is thus relevant to investigate which rationales are included in the knowledge base of journalism, as the dimension does...

  20. Reliability of journal impact factor rankings

    Directory of Open Access Journals (Sweden)

    Greenwood Darren C

    2007-11-01

    Full Text Available Abstract Background Journal impact factors and their ranks are used widely by journals, researchers, and research assessment exercises. Methods Based on citations to journals in research and experimental medicine in 2005, Bayesian Markov chain Monte Carlo methods were used to estimate the uncertainty associated with these journal performance indicators. Results Intervals representing plausible ranges of values for journal impact factor ranks indicated that most journals cannot be ranked with great precision. Only the top and bottom few journals could place any confidence in their rank position. Intervals were wider and overlapping for most journals. Conclusion Decisions placed on journal impact factors are potentially misleading where the uncertainty associated with the measure is ignored. This article proposes that caution should be exercised in the interpretation of journal impact factors and their ranks, and specifically that a measure of uncertainty should be routinely presented alongside the point estimate.

  1. Doing it for Real: Designing Experiential Journalism Curricula that Prepare Students for the New and Uncertain World of Journalism Work

    Directory of Open Access Journals (Sweden)

    Jeanti St Clair

    2015-03-01

    Full Text Available The world of journalism in the digital age is changing faster than university curricula can keep up. News is now produced in forms and on platforms that were nonexistent 10 years ago. Journalists may increasingly generate their own work opportunities in entrepreneurial news outlets and start-ups, rather than as employees in legacy newsprint and broadcast media. Substantial workforce contraction has also occurred since 2012 as revenue in print and other traditional media has found new homes in social media and search engines, and over 1000 journalists (or 15 percent of the journalism workforce were made redundant. Journalism graduates therefore need to be flexible, innovative and enterprising to survive professionally in this evolving setting. Additionally, financial and funding pressures on universities are leading them to reduce course costs and deliver more courses online. Elongated unpaid internships provide real world experience but access to these will likely reduce as workforces continue to contract. This article considers student feedback from three authentic experiential journalism projects in light of these changing times in journalism. It explores how the performative and very practical nature of traditional and digital journalism skills may be developed through a learning-centred curriculum anchored in authentic and experiential activities and settings. The article briefly considers some of the challenges facing journalism educators in delivering such a curriculum in e-learning settings, and sets out a simple framework for supporting the development of digital media workforce readiness.

    2014-07-01

    Large commercial publishers sell bundled online subscriptions to their entire list of academic journals at prices significantly lower than the sum of their á la carte prices. Bundle prices differ drastically between institutions, but they are not publicly posted. The data that we have collected enable us to compare the bundle prices charged by commercial publishers with those of nonprofit societies and to examine the types of price discrimination practiced by commercial and nonprofit journal publishers. This information is of interest to economists who study monopolist pricing, librarians interested in making efficient use of library budgets, and scholars who are interested in the availability of the work that they publish.

  8. Concentration in Knowledge Output: A case of Economics Journals

    Directory of Open Access Journals (Sweden)

    Paul Gopuran Devassy Bino

    2005-12-01

    Full Text Available This paper assesses the degree of author concentration in seven economics journals, which were published in India during 1990-2002. To measure the degree of author concentration, Lotka's Law was used. Moreover, we also make an exploratory analysis of the geographic, economics subfield and institutional concentration in 704 economics journals. An important finding of this paper is that specialized journals in the sample report the highest degree of author concentration. This result is quite similar to the findings by Cox and Chung (1991. Furthermore, there are several instances showing that the journals lean towards certain norms; this may affect the flow of innovative ideas into economics. We conclude that a knowledge activity, involving the high degree of concentration and a biased publication process, may affect the flow of new ideas into the discipline.

    Writing for publication is a fulfilling activity that strengthens our discipline by building the knowledge we need for practice. Most writing teams work in a collaborative manner to determine authorship credit depending on the relative intellectual contributions of each author. Written memos of understanding at the beginning of a project help to clarify roles and ensure appropriate recognition for all contributors. By respecting the importance of intellectual property, nurse authors can ensure that an entire writing team can receive the benefits of publishing together in peer-reviewed journals.

    2017-02-01

    There is a positive association between availability of regional peer-reviewed public health information systems and progressive change in community and population health. The objective of this brief report was to identify public health journals in Arabic-speaking countries actively publishing as of 2016. We conducted an electronic search in several electronic database records for public health journals using a combination of search terms. We excluded journals that focused on human medicine, veterinary medicine, nursing, and other discipline-specific or clinical health professions. We identified twenty-five public health journals for review. Five journals were interrupted or discontinued. Only three journals had a consistent, uninterrupted active publication history of greater than 20 years. Most journals were not in the regional native language. Introduction of regional public health-dedicated journals with in-print and electronic availability and also to be published in region-native languages may require interdisciplinary partnerships. Region-wide public health journals such as the Eastern Mediterranean Health Journal could serve as an ideal model for the establishment of additional local and regional public health journals in Arabic-speaking countries.

  3. Retracted Publications Within Radiology Journals.

    Science.gov (United States)

    Rosenkrantz, Andrew B

    2016-02-01

    The purpose of this study was to characterize trends related to retracted publications within radiology journals. PubMed was queried to identify all articles with the publication type "retracted publication" or "notification of retraction." Articles published within radiology journals were identified using Journal Citation Reports' journal categories. Available versions of original articles and publication notices were accessed from journal websites. Citations to retracted publications were identified using Web of Science. Overall trends were assessed. Forty-eight retracted original research articles were identified within radiology journals since 1983, which included 1.1% of all PubMed "retracted publication" entries. Distinct PubMed entries were available for the retracted publication and retraction notification in 39 of 48 articles. The original PDF was available for 37 articles, although the articles were not watermarked as retracted in 23 cases. In six cases with a watermarked PDF, further searches identified nonwatermarked versions. Original HTML versions were available for 13 articles but 11 were not watermarked. The mean (± SD) delay between publication and retraction was 2.7 ± 2.8 years (range, 0-16 years). The mean number of citations to retracted articles was 10.9 ± 17.1 (range, 0-94 citations). Reasons for retraction included problematic or incorrect methods or results (although it typically was unclear whether these represented honest errors or misconduct) in 33.3% of cases, complete or partial duplicate publication in 33.3% of cases, plagiarism in 14.6% of cases, a permission issue in 8.3% of cases, the publisher's error in 6.3% of cases, and no identified reason in 6.3% of cases. One or no retractions occurred annually from 1986 to 2001, although two or more retractions occurred annually in nine of the 12 years from 2002 through 2013. Retraction represents an uncommon, yet potentially increasing, issue within radiology journals that publishers

  4. A course in Peace Journalism

    Directory of Open Access Journals (Sweden)

    2007-04-01

    Full Text Available This article sets out a reasoned and annotated plan for a short course in Peace Journalism, suitable for teaching to students of Journalism, Communications, Media and Peace and Conflict Studies. It is based on courses the author has taught, over many years, and the aim of the article is to help teachers to devise their own courses. The best way to help students to begin thinking about issues in the representation of conflicts, the article argues, is to give them a flavour of it, by showing them different ways in which the same story can be told. The article gives story-boards and scripts for two television news treatments of the same event, a bombing in the Philippines. The first is an example of War Journalism, it is argued; the second, Peace Journalism. The article suggests ways to develop a course from this illustrative starting point, to ask why the distinctions between these two approaches should be considered important - both in their own terms, and in terms of their potential influence on the course of events in conflict. Different approaches to conceptualising and measuring this possible influence are discussed, with suggestions for further exploration. The article recounts some of the author's experiences in introducing and discussing what is, inevitably sometimes, difficult and sensitive material, with groups including participants from conflict-affected countries - Palestine, Israel and the Philippines. Not all students will be aspiring journalists. The article offers brief notes on practical Peace Journalism, as well as showing how learning outcomes can be formulated to allow the same issues to be tackled in the form of a civil society campaign, or as a peace-building intervention in conflict. The article also explains how students can be equipped to question elements of journalistic practice which they may take for granted, and which pass unexamined in many current journalism courses. That, in turn, entails examining the emergence

  5. Comparison of Journal Self-Citation Rates between Some Chinese and Non-Chinese International Journals

    Science.gov (United States)

    Yang, Zu-Guo; Gao, Feng; Zhang, Chun-Ting

    2012-01-01

    Background The past 3 decades have witnessed a boost in science development in China; in parallel, more and more Chinese scientific journals are indexed by the Journal Citation Reports issued by Thomson Reuters (SCI). Evaluation of the performance of these Chinese SCI journals is necessary and helpful to improve their quality. This study aimed to evaluate these journals by calculating various journal self-citation rates, which are important parameters influencing a journal impact factor. Methodology/Principal Findings We defined three journal self-citation rates, and studied these rates for 99 Chinese scientific journals, almost exhausting all Chinese SCI journals currently available. Likewise, we selected 99 non-Chinese international (abbreviated as ‘world’) journals, with each being in the same JCR subject category and having similar impact factors as their Chinese counterparts. Generally, Chinese journals tended to be higher in all the three self-citation rates than world journal counterparts. Particularly, a few Chinese scientific journals had much higher self-citation rates. Conclusions/Significance Our results show that generally Chinese scientific journals have higher self-citation rates than those of world journals. Consequently, Chinese scientific journals tend to have lower visibility and are more isolated in the relevant fields. Considering the fact that sciences are rapidly developing in China and so are Chinese scientific journals, we expect that the differences of journal self-citation rates between Chinese and world scientific journals will gradually disappear in the future. Some suggestions to solve the problems are presented. PMID:23173041

    h-index is useful for quantifying scholarly activity in medicine, but this statistic has not been extensively applied as a measure of productivity in anaesthesia. We conducted a bibliometric analysis of h-index in editorial board members and tested the hypothesis that editorial board members of anaesthesia journals with higher impact factors (IFs) have higher h-indices. Ten of 19 journals with 2009 IF>1 were randomly chosen from Journal Citation Reports(®). Board members were identified using each journal's website. Publications, citations, citations per publication, and h-index for each member were obtained using Scopus(®). Four hundred and twenty-three individuals filled 481 anaesthesia editorial board positions. The median h-index of all editorial board members was 14. Board members published 75 papers (median) with 1006 citations and 13 citations per publication. Members serving on journals with IF greater than median had significantly (Peditorial board members and its IF (h-index=3.01×IF+6.85; r( 2)=0.452; P=0.033) was observed for the 10 journals examined. Board members of subspeciality-specific journals had bibliometric indices that were less than those at general journals. The h-index was greater in individuals serving more than one journal. European editorial board members had higher h-index values than their American colleagues. The results suggest that editorial board members of anaesthesia journals with higher IFs have higher h-indices.

  8. High-impact medical journals and peace: a history of involvement.

    Bloom, Joshua D; Sambunjak, Dario; Sondorp, Egbert

    2007-01-01

    The aim of this study is to explore the positions of five leading general medical journals (The Lancet, British Medical Journal--BMJ, Journal of American Medical Association--JAMA, New England Journal of Medicine--NEJM, and Annals of Internal Medicine--AIM) toward the issues of collective violence. We calculated the proportion of war-related articles in the total number of articles published in these five high-impact journals, and in the total number of articles indexed in PubMed during the last 60 years. The results showed a continuous increase in the proportion of war-related articles. Our findings suggest that the leading general medical journals have taken an active editorial stance toward the issues of war and peace. We conclude that high-impact medical journals can make an important contribution to efforts aimed at reducing the risks and consequences of war and violence.

  10. Introducing a Concept Hierarchy for the Journal of Research Practice

    Directory of Open Access Journals (Sweden)

    Werner Ulrich

    2011-01-01

    Full Text Available With this issue of the Journal of Research Practice, we initiate a conceptual framework for thinking and writing about research, defining areas of editorial focus, and indexing work published in the journal. The framework takes the form of a concept hierarchy that offers index terms at three interrelated levels: (1 focus areas for reflection on research practice within which the journal aims to achieve excellence and strengthen its profile and visibility, (2 subject areas relevant to research practice that the journal aims to cover and in terms of which it defines its focus areas, and (3 keywords for capturing the content of research work done in these subject areas or for reflecting and writing about it. Focus areas are characterized by assigned subject areas; subject areas are characterized by assigned keywords. The concept hierarchy is part of a more comprehensive initiative to strengthen the journal's profile and visibility, an initiative that will also include a restructuring of the editorial team and new roles for the journal's dedicated reviewers and active readers. The article introduces an initial version of the concept hierarchy, explains its intended use and further development, and situates it in the larger effort of which it is a part.

  11. On the future contents of a small journal of histochemistry

    Directory of Open Access Journals (Sweden)

    C. Pellicciari

    2012-12-01

    Full Text Available In the last three years, more than 70,000 scientific articles have been published in peer reviewed journals on the application of histochemistry in the biomedical field: most of them did not appear in strictly histochemical journals, but in others dealing with cell and molecular biology, medicine or biotechnology. This proves that histochemistry is still an active and innovative discipline with relevance in basic and applied biological research, but also demonstrates that especially the small histochemical Journals should likely reconsider their scopes and strategies to preserve their authorship. A review of the last three years volumes of the European Journal of Histochemistry, taken as an example of a long-time established small Journal, confirmed that the published articles were widely heterogeneous in their topics and experimental models, as in this Journal’s tradition. This strongly suggests that a Journal of histochemistry should keep its role as a forum open to an audience as broad as possible, publishing papers on cell and tissue biology in a wide variety of models. This will improve knowledge of the basic mechanisms of development and differentiation, while helping to increase the number of potential authors since scientists who generally do not use histochemistry in their research will find hints for the applications of histochemical techniques to novel still unexplored subjects.

    1998-01-01

    We are happy to introduce you the first issue of the new "The European Physical Journal - Applied Physics". The aim of this initiative, which concretises the merging of two well-known French journals, "the Journal de Physique III" and "Microscopy, Microanalysis, Microstructures", is to initiate within a European perspective the basis of an international journal of Applied Physics. This creation accompanies the broader movement opened with the merging of the more than centennial publications namely, "Journal de Physique" and "Zeitschrift für Physik", in order to give birth to an attractive forum for all those involved in this field of activity, in the European physics community evidently but also all around the world. This journal covers a wide range of domains in materials science, optics, electronics and instrumentation in general: a more comprehensive list of topics is given on page A6.The journal is represented in a large number of countries thanks to our team of Associate Editors working in close collaboration with the central editorial offices: the one in Paris at the headquarters of the French Society of Microscopies is more specific for the authors submitting manuscripts involving all types of microscopies and analysis techniques together with their use for materials characterization, while the Orsay office is intended to process all the other types of papers. However you can also submit your manuscripts directly to any of the Associated Editors listed on the title page of the journal. With the support of the staff of EDP Sciences we will all devote our efforts to insure fast and high quality production."EPJ Applied Physics" will appear monthly. Submission is welcome electronically as well as in paper form; see the conditions reported on the previous pages.

    The impact factor has become the subject of widespread controversy. It has gradually developed to mean both journal and author impact. The emphasis on impact factors obscures the main purpose of bibliographic databases created at the Institute for Scientific Information. I will here show how two of these databases, Journal Citation Reports and the Journal Performance Indicators, can be used to study scientific journals and the articles they publish, as well as the evolution of scientific fields.

  15. Clinical trial registration in oral health journals.

    Smaïl-Faugeron, V; Fron-Chabouis, H; Durieux, P

    2015-03-01

    Prospective registration of randomized controlled trials (RCTs) represents the best solution to reporting bias. The extent to which oral health journals have endorsed and complied with RCT registration is unknown. We identified journals publishing RCTs in dentistry, oral surgery, and medicine in the Journal Citation Reports. We classified journals into 3 groups: journals requiring or recommending trial registration, journals referring indirectly to registration, and journals providing no reference to registration. For the 5 journals with the highest 2012 impact factors in each group, we assessed whether RCTs with results published in 2013 had been registered. Of 78 journals examined, 32 (41%) required or recommended trial registration, 19 (24%) referred indirectly to registration, and 27 (35%) provided no reference to registration. We identified 317 RCTs with results published in the 15 selected journals in 2013. Overall, 73 (23%) were registered in a trial registry. Among those, 91% were registered retrospectively and 32% did not report trial registration in the published article. The proportion of trials registered was not significantly associated with editorial policies: 29% with results in journals that required or recommended registration, 15% in those that referred indirectly to registration, and 21% in those providing no reference to registration (P = 0.05). Less than one-quarter of RCTs with results published in a sample of oral health journals were registered with a public registry. Improvements are needed with respect to how journals inform and require their authors to register their trials.

  17. Editorial: Journal of Comparative Psychology.

    Burghardt, Gordon M

    2006-05-01

    Both continuity and change typically mark the changing of editors at a long-established journal with extended editorial terms. Change is inherent in any dynamic field and is independent of editorship, but editors have an influence that should be wielded in a fair, responsible, judicious, and scientifically rigorous manner, while inevitably reflecting their own perspectives and values. The Journal of Comparative Psychology will continue to publish exciting, fascinating, assessable, controversial, and well-written reports on research, be the topic traditional, interdisciplinary, applied, or one breaking risky new ground. Editorial standards must be high, but appropriate for various subfields, and as editor the author will try to make those judgments carefully. The author would also like to see more submissions of brief reports describing exciting developments as well as submissions on significant theoretical, conceptual, and methodological issues during his tenure as editor.

  18. Book reviews in medical journals.

    Science.gov (United States)

    Kroenke, K

    1986-01-01

    In a study of book reviews published in four general medical journals over a six-month period, 480 reviews were analyzed. Twenty-five features that reviewers address when evaluating a text were identified, and the frequency of commentary for each feature was determined. The mean number of features addressed per review was 9.0. Reviews averaged 389 words, but review length did not correlate with the length or scope of the book, with the number of features addressed, nor with the reviewer's assessment of the text. Extraneous commentary by the reviewer occurred in 16% of the reviews. This editorializing appeared in lengthier reviews that addressed fewer features. Favorable reviews were far more common than unfavorable ones (88.5% vs. 11.5%). Consequently, for the fifty-five books reviewed in more than one journal, agreement regarding rating of the text was high (86%). Results of this study may provide useful guidelines for reviewers of medical texts.

  19. Visualization of the Citation Impact Environments of Scientific Journals: An online mapping exercise

    CERN Document Server

    Leydesdorff, Loet

    2009-01-01

    Aggregated journal-journal citation networks based on the Journal Citation Reports 2004 of the Science Citation Index (5968 journals) and the Social Science Citation Index (1712 journals) are made accessible from the perspective of any of these journals. The user is thus able to analyze the citation environment in terms of links and graphs. Furthermore, the local impact of a journal is defined as its share of the total citations in the specific journal's citation environments; the vertical size of the nodes is varied proportionally to this citation impact. The horizontal size of each node can be used to provide the same information after correction for within-journal (self)-citations. In the "citing" environment, the equivalents of this measure can be considered as a citation activity index which maps how the relevant journal environment is perceived by the collective of authors of a given journal. As a policy application, the mechanism of interdisciplinary developments among the sciences is elaborated for th...

  2. CERN Library - Scientific journal cancellations

    CERN Multimedia

    2004-01-01

    Due to the constant increase of the subscription costs of scientific journals and the current budget restrictions, the Scientific Information Policy Board has mandated the Working Group for Acquisitions (WGA) together with the Library to propose a list of titles to be cancelled at the end of 2004. As a first step, the WGA has identified the scientific journals listed at the web site below as candidates for cancellation. The choice has been guided by the personal experience of the WGA members, consultation of other expert CERN staff for highly specialized titles, and by criteria such as subscription price, impact factor, and - where available - access statistics for electronic journals. The list also accounts for the fact that many titles are subscribed to in 'packages' such that a cancellation of individual titles would not lead to any cost savings. We invite users to carefully check the list on the Library homepage (http://library.cern.ch/). If you find any title that you consider critically important for y...

    2016-11-01

    The purpose of this study was to identify predatory journals in nursing, describe their characteristics and editorial standards, and document experiences of authors, peer reviewers, and editors affiliated with these journals. Using two sources that list predatory journals, the research team created a list of nursing journals. In Phase One, the team collected data on characteristics of predatory nursing journals such as types of articles published, article processing charge, and peer review process. In Phase Two, the team surveyed a sample of authors, reviewers, and editors to learn more about their experiences with their affiliated journals. Data from the review of predatory nursing journals were analyzed using descriptive statistics. Written comments were summarized and categorized. There were 140 predatory nursing journals from 75 publishers. Most journals were new, having been inaugurated in the past 1 to 2 years. One important finding was that many journals only published one or two volumes and then either ceased publishing or published fewer issues and articles after the first volume. Journal content varied widely, and some journals published content from dentistry and medicine, as well as nursing. Qualitative findings from the surveys confirmed previously published anecdotal evidence, including authors selecting journals based on spam emails and inability to halt publication of a manuscript, despite authors' requests to do so. Predatory journals exist in nursing and bring with them many of the "red flags" that have been noted in the literature, including lack of transparency about editorial processes and misleading information promoted on websites. The number of journals is high enough to warrant concern in the discipline about erosion of our scholarly literature. Nurses rely on the published literature to provide evidence for high-quality, safe care that promotes optimal patient outcomes. Research published in journals that do not adhere to the highest
