    As the successor to Professor Teruo Kishi, the former Editor-in-Chief of Science and Technology of Advanced Materials (STAM), I would like to share some of STAM's journal history with our readers. STAM was launched in 2000 with the financial support of the Japanese Ministry of Education, Culture, Sports, Science and Technology in recognition of a strong need for an international journal that would be distributed and read across the globe. Five years later, the publication of STAM was transferred to the National Institute for Materials Science (NIMS) under the initiative of Professor Kishi. As a result of his work, STAM is now positioned as a high-impact journal, 3.512 as listed by the ISI 2011 Science Citation Index Journal Citation Report, with a much higher and faster growth than when I was participating as a co-founder in the past. STAM is well known as a successful open-access journal since shifting from the initial subscription model in 2008. As an editor, I would like to emphasize that STAM will continue to publish with a sense of social mission as an academic journal, allowing space for researchers to contribute to the sustainable development of society and health. However, some contribution from authors would assist us in creating a sustainable journal publishing model, and further enhance services to authors and readers of STAM. With this in mind, I would like to state that STAM's editorial board is planning to introduce an article processing charge from July 2013, in addition to NIMS' continuing financial support. One of our new editorial policies is to aim for reader-oriented publishing. I believe that academic journal publishing can take the role of navigator in advancing the development of materials. Among the many other scientific journals, STAM will lead the rapid growth in materials science, inspiring research into new materials for the future and leading the next generation of materials science and technology. It is my honor to work with members of

    It is my pleasure to welcome the authors and readership of Plasma Sources Science and Technology (PSST) to volume 17. We have enjoyed a successful 16 years of growth under the guidance of our founding Editor-in-Chief, Professor Noah Hershkowitz, resulting in PSST gaining the confidence and respect of the plasma community. PSST has established itself as the journal of choice for dissemination of research results on the fundamentals of low-temperature plasmas. It has achieved this position through its rigorous reviewing process that improves the quality of our already excellent contributions. This was accomplished with the dedicated efforts of our reviewers and cooperation of our authors, to whom I am grateful. I am hoping we can continue to count on your support. I am confident that we will build upon our past successes by continuing to improve the journal and better serve the low temperature plasma community. I am pleased to introduce Professor William G Graham (Queen's University of Belfast) and Professor M C M (Richard) van der Sanden (Eindhoven University of Technology) who have joined the leadership team as Associate Editors. I am also pleased that Professor Hershkowitz has agreed to continue to serve PSST as an Associate Editor. Bill, Richard and Noah will share the editorial duties with me in selecting referees, assessing their comments and communicating with authors. Ms Caroline Wilkinson will continue to expertly serve as our IOP Publishing contact. The Editorial Board is critically important to the continued success and growth of the journal. Their efforts in providing advice and guidance, and in suggesting (and often guest editing) special issues are greatly appreciated. As we enter our seventeenth year, it is an appropriate time to revisit the guiding principles of the journal. PSST serves a unique mission in addressing fundamental issues in the science and technology of low-temperature plasmas and so distinguishes itself from more applications

    It is both an honour and daunting to be associated with a successful, long-lived journal. An honour because the journal already enjoys a high reputation, not only for the quality of its articles but also for the manner in which it has encouraged areas to grow and develop towards their own specialized publications. Daunting because maintaining the quality of the journal is a challenge needing constant vigilance and innovation. Moreover, I am conscious of all the work which has been done by my predecessors. Jean Zinn-Justin is the most recent and I should like to take this opportunity to thank him for all he has done so generously over the past five years. The journal relies on the partnership between its authors, its referees, the Editorial Board and the publishers. Its principal purpose is to provide, selectively, an archive for the physics community and it is essential that authors are eager to submit their papers in the knowledge that they will be treated fairly and rapidly, that the referees perform their role willingly and constructively, and that the international Editorial Board encourages both in their tasks, and solicits submissions from physicists working in budding areas. Besides co-ordinating the production of the journal, the publishers are developing ways to assist the community to perform its research. For example, the online electronic version of the journal is hugely successful with over 75,000 e-accesses in 1998. HyperCite is an exciting development which is beginning to link papers together in an unprecedented manner. It will take time to perfect this service but its use is growing apace. Moreover, approximately one half of all submissions to the journal are now via electronic means. Of course, many authors place their papers on other, freely available, electronic archives and these are valuable. Nevertheless, the sifting process provided by the referees and editorial board of a journal remains an essential part of the scientific evaluation of a

    Even as I write this editorial, the Ides of March approach rapidly. This is unnerving and depressing because it signals that, in the United States, April Fool's Day is only a month away. I realize that some of you will quickly seize the opportunity to expose my error and point out that April 1st is only two weeks after March 15th-not a month. While I cannot disagree that April 1st occurs only two weeks after March 15th, I must nevertheless claim that April Fool's Day really falls on April 15,* the day we are called upon to account for our income-producing activities of the previous year. Yes, that is the day we are required by the IRS (Incentive Reduction System) to pay for our financial indiscretions of accum ulating wealth the old-fashioned way-by earning it. At least we can take comfort in knowing that the process of paying our taxes was made much simpler and more equitable when the 1986 Tax Reform Act l" went into effect.

    This editorial presents an overview of the articles contained in this issue of Gender and Development, addressing the key themes of globalization and diversity. The collection of articles recalls why the project of promoting gender-equitable development continues to be critical in the 21st century, identifies some key challenges confronting those working on gender development, and takes a brief look at some examples of innovative work. This collection begins with a group of articles examining economic, political, and social changes associated with globalization, and analyzing their positive and negative impacts on different men and women. The ways in which specific aspects of globalization affect gender relations and shape the choices and chances of men and women are traced. In particular, writers highlight the failure of governments and development agencies to challenge fully the false assumptions about the nature of the role of men and women in society upon which global activity is based. Drawing on insights from academic research and feedback from practitioners, the second group of articles presents the basic concepts and terminology used in gender and development work. Lastly, the third group of articles offers innovative case studies of current gender-sensitive development work. Emphasis is placed on topical issues, including acknowledgment of sexuality as a development issue, critique on the assumption of entrepreneurship as gender neutral, and the assertion of the need for mainstream institutions, including government and development funders to work with women's organizations.

    This editorial introduces a journal devoted to the issues surrounding women and their rights. As the development debate moves from women's need to their rights and to an understanding of the cultural roots of legal systems and the effects of the mass media in presenting alternative life styles as possibilities, the immense implications of using rights-based language in development emerge. This debate moves women from being the recipients of welfare to a state of empowerment. Women must be afforded individual rights which are linked to community rights. In addition, rights must be granted to women in their public and private domains. The dangers of using a rights-based language to assert women's claims to economic, political, and social equality in economic, political, and social life arise from the reality that the social position of men will usually place men at an advantage with the law. Legal processes which stress dichotomies may fail to improve real social situations. Also, the language of human rights may pit one set of rights (a woman's right to choose abortion) against another (the fetuses' right to live) to women's disadvantage. Areas governed by both customary and civil law pose other difficulties, especially since they require women to understand the law in order to use it. Development efforts which stress rights hope to meet immediate needs and to achieve a strategic end. Nongovernmental organizations can play an important role in asserting and enforcing the freedom of individuals and groups within groups. They can also build capacity at all levels of society and explore linkages between women's economic participation, decision-making within the home, and wider political participation.

    1993-10-01

    This editorial introduces an issue of a journal which contains articles on the themes of 1) macroeconomic policy and gender relations and 2) income generation projects and empowerment. The opening paper dispels the myth that economic policies are gender-neutral. Another article uses the effects of structural adjustment policies in the Caribbean to illustrate how such policies increase women's burdens because of cuts in social services and pressures on women to provide cheap labor to create export goods. A third article depicts the adverse consequences of a macroeconomic policy in India which favors exports over domestic production. This theme is developed in a paper which challenges the notion that export-oriented development strategies provide a "trickle down" benefit to the poor. Specific reversals in development advances in Tanzania are linked to the adjustment experience, and the policy of debt repayment at all costs in the Philippines is shown to have an adverse effect on the poor. Other papers from Albania, India, Tanzania, Chile, and Bangladesh highlight how market-oriented reforms have created conditions which are detrimental to women's health. Further research reveals that the touted "feminization of employment" has actually turned out to be a "feminization of unemployment" as gender discrimination in the labor market continues. Papers on income-generating projects spotlight what has been learned about developing a successful income-generation project which recognizes women's "reproductive labor" time demands. Other articles explore barriers faced by women to access to finance and entrepreneurship. By looking beyond economic jargon and false assumptions, the authors of these papers explore how gender relationships are shaped by economic policies and affect policy outcomes and how women are organizing to improve their lives and the health of their communities.

    As we close volume 21 of Semiconductor Science and Technology it is interesting to reflect on the achievements of the year. Notable this year has been the considerable increase in submissions to the journal. As of the end of October we had received a 26% increase in submissions compared to the same time last year. This has naturally had a considerable impact on the number of referees we need in order to maintain the high quality standards of the journal. In the first ten months of this year Semiconductor Science and Technology approached 1468 referees based in 36 different countries. Of the 1468 referees asked to review an article just under half, 723, wrote a report. Excluding members of the Editorial Board, who often review one or more articles a month, our `most hard-working' referee reviewed 6 articles for us in the first ten months of this year. In order to provide a timely publication decision for our authors we ask referees to prepare a review within 21 days. The average time for a referee to report is just under this at 18 days. Our fastest review this year so far was an impressive 2 hours and 5 minutes. Managing the peer review for a growing journal like Semiconductor Science and Technology would be a far more difficult task if it were not for the many conscientious referees who review articles for us. We would like to take this opportunity to express our thanks to all of our referees from this and previous years. We value your careful and well constructed reports which are of great assistance to us in maintaining the rigorous quality standards of Semiconductor Science and Technology.

    To open this first issue of 2009 I would like to update you on the current state of the Journal and to look ahead to our plans and goals for the year ahead. I am delighted to report that Plasma Sources Science and Technology (PSST) is in excellent health and in 2008 enjoyed the highest number of annual submissions in its history. The number of papers downloaded from our online services increased by 25% compared with the previous year, indicating that the Journal is reaching a wider audience than ever before. Our Impact Factor (2.12) remains high and very competitive with other journals in the field. The success of the Journal is of course a reflection of the excellent research which is being conducted by the plasma physics community. I extend my thanks to our authors for continuing to choose PSST as a forum to report on for their outstanding work and to our referees, whose insightful comments and constructive criticism are instrumental in maintaining the quality of our publication. My many thanks also go to Richard van de Sanden, Bill Graham and Noah Hershkowitz and to the team at IOP Publishing who have supported me through my first full year as Editor-in-Chief. I particularly thank Caroline Wilkinson for her mentoring guidance. At the beginning of 2008 we introduced a revised Editorial Policy which emphasized the need for all papers submitted in PSST to focus on fundamental plasma properties (http://www.iop.org/EJ/journal/-page=scope/0963-0252 link to scope page). Our intention was to re-affirm the original guiding principles of the Journal and to strengthen its identity as a unique destination for research into the fundamental science of low temperature plasmas. The task of enforcing this policy---while remaining responsive to new areas of research---has proven to be quite a challenge. On occasion deciding whether a submission falls within or outside of the editorial policy comes down to a 'judgement-call' on the part of the editorial team. It is in cases like

G is at an exciting juncture in its history, with 2005 marking the journal's 31st year of publication. In the past few years the journal has truly blossomed under the guidance of its previous Editors, Lee Schroeder and Horst Stöcker, and I look forward to building on their excellent work towards developing the journal to its full potential. Since 2001, article submissions have increased by 55% and the average time from receipt of a paper to a first decision has decreased to only 45 days. Last year J. Phys. G redrafted its scope to strengthen its support for physicists working in the interface areas where nuclear physics, particle physics and astrophysics meet, sharing common goals and language, as well as instrumentation techniques. J. Phys. G has been very successful in attracting papers in these interface areas, especially in quark matter physics by developing close relationships with this community. As Editor, I plan to continue to broaden the spectrum covered and especially to strengthen our coverage in the areas of neutrino physics and fundamental symmetries, whilst keeping the coverage of hadron physics and quark matter strong. I will work closely with our distinguished Editorial Board and excellent editorial team to ensure that we continue raising the quality of accepted papers in the journal and keep processing times to a minimum. With this team in place, I am confident that J. Phys. G will continue to go from strength to strength. Finally, a journal's success depends very much on the efforts of the volunteer referees and I thank them for all their hard work.

    With this editorial note we would like to update you on the performance of the International Journal of Applied Earth Observation and Geoinformation (JAG) and inform you about changes that have been made to the composition of the editorial team. Our Journal publishes original papers that apply earth observation data for the management of natural resources and the environment. Environmental issues include biodiversity, land degradation, industrial pollution and natural hazards such as earthquakes, floods and landslides. As such the scope is broad and ranges from conceptual and more fundamental work on earth observation and geospatial sciences to the more problem-solving type of work. When I took over the role of Editor-in-Chief in 2012, I together with the Publisher set myself the mission to position JAG in the top-3 of the remote sensing and GIS journals. To do so we strived at attracting high quality and high impact papers to the journal and to reduce the review turnover time to make JAG a more attractive medium for publications. What has been achieved? Have we reached our ambitions? We can say that: The submissions have increased over the years with over 23% for the last 12 months. Naturally not all may lead to more papers, but at least a portion of the additional submissions should lead to a growth in journal content and quality.

    We are pleased to present this Second Special Issue on Interdisciplinary Aspects of Piezoelectric Technologies in Integrated Systems. The first issue of this series was published in March 2013 (MSSP, vol. 36(1)) and contained chosen articles presented at the International Conference on Mechatronic Systems and Materials as well as regular papers on this subject. This first issue contained 17 articles presenting the state of the art regarding the control and practical use of piezoelectric materials. It should be noted that the development of science in this area is very rapid, has a multidisciplinary character and encompasses many areas of science. Thus the decision to publish a new issue from the 'Piezoelectricity' series, to sum up recent works in this area. Similarly to the first issue, some the articles were based on presentations at the 8th International Conference 'Mechatronic Systems and Materials' held in July 2014 in Opole, Poland, and others having been submitted as regular articles to the editorial office. For this Special Issue, 12 articles were chosen, being thematically divided according to the following issues: piezoelectric actuators (5 articles), design and control issues regarding piezoelectric transducers (2 articles), detection of damage in the laboratory and technical scale (3 articles), modeling of discrete systems using piezoelectric materials (1 article), and the construction and control of measurement systems based on piezoelectric sensors (1 article). A brief summary about the content of the articles has been presented below.

    An editorial may be written by the editor or someone invited by the editor. It serves many other purposes, including critiques of original articles published in the same issue of the journal, concise reviews of topics that do not warrant a full-length invited review, and other topics on very recent developments that are deemed by the editor to be important to readers of the journal and the community. As there is typically a limited space in which to deliver its contents, the message contained in the editorial needs to be well thought out and concisely delivered. It should contain the correct sequence of the elements of critical argument, ideally supported by evidence, and end with a clear conclusion.

A balance is needed among several parameters such as level of evidence, probability that the evidence will lead to a specific direction and the cost to the global community. 1 tab.

    I am delighted to inform you that from January 2010 Professor Alfred K Louis of the University of Saarland, Germany, will be the new Editor-in-Chief of Inverse Problems. Alfred joins us with a wealth of experience and a great deal of respect from the community. He has served the journal in a number of ways as an Editorial Board member, outstanding reviewer and author. We very much look forward to working with him to continue to publish the highest quality articles in the field and build on our extremely successful special section and topical review programmes. Whilst welcoming Alfred to the position, we are also keen to thank our outgoing Editor-in-Chief, Professor Bill Symes, for the fabulous job that he has done over the past five years. Under Bill's direction, Inverse Problems has gone from strength to strength. In fact, in the last year we have taken the step of moving from six to 12 issues a year, reflecting the increased number of high-quality papers submitted to the journal. During the last five years we have published a wide range of fantastic special sections and topical reviews, including a celebration of the journal's 25th year (issue 12 2009), in which Bill played a pivotal role. We are very much looking forward to 2010 and will be celebrating our 25th birthday further with a selection of highlighted articles chosen from the past 25 years. We hope that you will continue to enjoy reading the journal. If you have any feedback, comments or questions, please do not hesitate to contact us at ip@iop.org. Zoë Crossman Publisher

    Blackburn, D. A.

    1990-01-01

    Since its first issue in 1965 Metrologia has had just three editors, a history of tenure which suggests that those who hold the post find in it sufficient to interest, occupy, challenge and amuse them. I see no reason to doubt that this happy circumstance will continue and look forward to my own period as editor with the intention of retaining, insofar as I am able to interpret them, the best traditions the journal has established so far. As I take up my editorial duties I have become aware that surrounding Metrologia there is a small community of authors, reviewers and readers on whose support the success of the journal entirely depends. It is a community in which the roles change daily with some of its members engaged, even simultaneously, as reader, reviewer and author. I am well aware that the goodwill extended to me as I enter this community is in no small part due the efforts of the outgoing editor, Dr Ralph Hudson, whose easy, engaging and courteous, yet firm, relationship with authors and reviewers emerges clearly from editorial correspondence. I thank him for that he has done and wish him an active and happy retirement. A short foray into the records of Metrologia shows - in the first editorial - that four main kinds of article were originally envisaged: research articles likely to contribute to progress in fundamental scientific measurements, reports of experiments or techniques of particular importance or originality in the area of secondary measurement, articles concerning the decisions of the Comité International des Poids et Mesures, and review articles. No balance was specified but a priority was assigned to articles dealing with fundamental metrology. Of the four categories, the first two represent the core of Metrologia's activity and largely determine its reputation as a publication. For this reason, editorial implementation of the policy set by the CIPM is mainly exercised through the operation of a reviewing system which is intentionally strict

    With this issue, beginning Volume 121, the editorial team shifts from the strong leadership of David Watson to a team under my direction. Approaching 125 years of publication, the Journal of Abnormal Psychology has earned its place as the preeminent outlet for research in psychopathology. With gratitude to the newly assembled team of associate editors (AEs), consulting editors, and ad hoc reviewers, I look forward to guiding the journal through this next term. Nine well-respected scholars have agreed to serve as AEs: Timothy Brown, Laurie Chassin, Jeff Epstein, Jutta Joormann, Pamela Keel, Kate Keenan, Scott Lilienfeld, Angus MacDonald, and Michael Young. The new team is dedicated to working tirelessly to maintain and enhance the journal's esteemed tradition of excellence. Given the well-established strengths of the journal, I will not suggest any fundamental changes.

    As many of you are aware that Chinese science is at the crucial stage of development. We are now seeing more and more high quality works being produced by Chinese scientists working in China. However, high quality scientific works are rarely published in Chinese scientific journals so far. Therefore, the development of scientific journals publishing in China now becomes a more and more important indication of the science development in China. In the development of the chemical physics research field in China, the Chinese Journal of Chemical Physics (CJCP) has made significant contributions in the past 18 years. Since CJCP is primarily a Journal published in Chinese previously, its impact in the international scientific community has been quite limited. At this moment, we believe CJCP should increase its impact in the international community. We believe that making CJCP an English journal is a crucial step to increase its influence internationally. Therefore, upon the recommendation of senior editorial members, we now change CJCP into an full English journal from this issue on. We have also formed a high quality editorial board to help the editorial matters in CJCP, and a prestigious advisory board to advise us of the future development. I am very honored to be selected as the new Editor-in-Chief for the next four years. I hope by the end of my term, the impact of this journal is significantly improved through the efforts of our editorial team. Building a high quality scientific journal is not an easy task. I hope that every member of our chemical physics community can provide strong support to this journal by sending your high quality research papers in the future. We are also thinking about adding new sections of this journal to attract more readers. With the support of our community, I am confident that we can make this journal a more successful one. Here, I want to take this opportunity to thank the great leadership provided by the Editor-in-Chief since the

    At 10:30 a.m. EST on January 28, 1986, 73 seconds after liftoff from its Cape Canaveral launch pad, the space shuttle Challenger was destroyed by a catastrophic explosion and the seven crew members aboard were killed. I wish to dedicate this editorial to the memory of her crew: Francis R. Scobee-Shuttle Commander, Michael J. Smith-Shuttle Pilot, Ronald E. McNair-Mission Specialist, Ellison S. Onizuka-Mission Specialist, Judith A. Resnik-Mission Specialist, Gregory B. Jarvis-Payload Specialist, Christa McAuliffe-Space Flight Participant. I believe that I am speaking for all the officers, governors, members, and staff of SPIE in expressing our heartfelt sorrow to the families and friends of these seven dedicated space pioneers. I also trust that I am speaking for all of us in SPIE in encouraging the United States to press ahead with its space program and to ensure that the Challenger's crew did not give their lives in vain.

    Summary Objectives To provide an editorial introduction into the 2014 IMIA Yearbook of Medical Informatics with an overview of the content, the new publishing scheme, and upcoming 25th anniversary. Methods A brief overview of the 2014 special topic, Big Data - Smart Health Strategies, and an outline of the novel publishing model is provided in conjunction with a call for proposals to celebrate the 25th anniversary of the Yearbook. Results ‘Big Data’ has become the latest buzzword in informatics and promise new approaches and interventions that can improve health, well-being, and quality of life. This edition of the Yearbook acknowledges the fact that we just started to explore the opportunities that ‘Big Data’ will bring. However, it will become apparent to the reader that its pervasive nature has invaded all aspects of biomedical informatics – some to a higher degree than others. It was our goal to provide a comprehensive view at the state of ‘Big Data’ today, explore its strengths and weaknesses, as well as its risks, discuss emerging trends, tools, and applications, and stimulate the development of the field through the aggregation of excellent survey papers and working group contributions to the topic. Conclusions For the first time in history will the IMIA Yearbook be published in an open access online format allowing a broader readership especially in resource poor countries. For the first time, thanks to the online format, will the IMIA Yearbook be published twice in the year, with two different tracks of papers. We anticipate that the important role of the IMIA yearbook will further increase with these changes just in time for its 25th anniversary in 2016. PMID:24853037

    With effect from August 2004 the journal Nanotechnology will discontinue the `Letters to the Editor' section. The increase in publication speed achieved for all articles now means that letters have no advantage. Fully electronic publication processes including electronic submission, refereeing and proofing, ensure that all papers are processed with minimum delay and are published as soon as they are ready. The journal will continue to publish high-quality original research papers, reviews and tutorials, as well as papers on the ethical and societal implications of nanotechnology at the discretion of the Editorial Board. All submitted papers will undergo a pre-selection procedure for suitability by the Editors of the journal. If a paper is accepted for consideration by the journal it will be sent to independent experts in the field for peer review. To speed up the publication process, we encourage authors to suggest five independent experts in their field as potential referees and supply their title, name, affiliation and e-mail address. The Editors of the journal may use these names at their discretion. Authors may also request that certain people are not to be used as referees. Papers of special interest will be given the utmost priority and on acceptance will be publicized further through worldwide press releases and reviews on the Institute of Physics website and on nanotechweb.org. As a service to authors and to the international physics community, and as part of our commitment to give authors' work as much visibility as possible, all papers are freely available online for 30 days from their electronic publication date. This means open access for citations to everyone in the world. We will also send an electronic offprint of your published paper to ten colleagues of your choice, giving your article an increased chance of being cited quickly. In the meantime, we are pleased to announce an increase in the Impact Factor of the journal in 2003 to 2.304, which means

    oscillating light `waves' had to be quantized as well. Several articles in this issue of Physics Education celebrate the first year of the quantum, 1900. I am grateful and beholden to Board Member and co-editor Gren Ireson for his contacts and nomination of the various contributors. It does seem strange, however, a full century after its discovery full of its amazing success that the essential quantum nature of practically everything is still kept hidden from school students, in the UK at least. Let's see what happens in the coming century. Now for another quantum leap. This is the last issue of Physics Education that I shall have the honour of editing. In fact, I shall leap into historical obscurity as the very last honorary editor. Great efforts by your Editorial Board - over a fair number of years! - have resulted in a radical reorganizing of both the journal and the way it is produced. It's been an interesting five years, a time of falling numbers but quite radical innovations in post-16 physics education. IoPP and the IoP are working together to revitalize what may have been seen by many as a staid if respectable and authoritative publication. We shall keep the authority and even respectability but hope to liven things up a bit. The new editor is Kerry Parker of Sheffield College. She will take on a stronger role than I and my predecessors have had, and will be working at IoPP in Bristol two days a week. There are many obvious advantages in this, and I look forward to seeing the new design and approach that will start with the January 2000 issue. So, it's goodbye from me - and also from the unsung heroine of Physics Education for even longer. Managing Editor Dr Jill Membrey has been doing the really hard work at Bristol for many years, but is now moving on to other things at IoPP. I am extremely grateful for the highly professional care and support she has provided for myself and the Editorial Board over the years. The new Managing Editor is Andrea Pomroy, who arrives at

Now, let us be clear about one thing for a start. This is not some less than subtle bid to take over the Editorship of this journal (proof by induction: you write editorials, therefore you are the editor). Fear not, readers, there is no revolt in the ranks! Fans of Ken Dobson will be glad to know that he will return to this space soon. My presence on successive occasions is just an unfortunate coincidence of timing. This issue is one of our regular special features where we take a topic and dedicate the journal to its exploration. Colleagues reading this in universities or colleges of higher education will forgive (I hope) the bias of this edition to `From the Classroom'. We intend this issue to launch a column that will be regular, but not necessarily in every issue, in which ideas taken from the classroom experience of our readers are presented. With that in mind, we openly invite contributions for this column. The sort of thing we are looking for is that tip, experiment, way of explaining an idea or nice example of a principle, which may not be of your own invention but may well be new to inexperienced teachers or new recruits to the profession. It is not just limited to those at the chalk face. We will welcome contributions from Heads of Department and Heads of Science who may well have valuable advice and hints to pass on to people taking on departmental responsibilities. There are myriad problems associated with departmental budgets, examinations, management of resources and people etc that the newly promoted have to face from day one. We can all learn from the experience of others. The contributions need not be long; they can be in the form of a paper or a letter or a brief remark. The important thing is that, just because you have known about a trick of the trade for as

    Physical Biology is a new peer-reviewed publication from Institute of Physics Publishing. Launched in 2004, the journal will foster the integration of biology with the traditionally more quantitative fields of physics, chemistry, computer science and other math-based disciplines. Its primary aim is to further the understanding of biological systems at all levels of complexity, ranging from the role of structure and dynamics of a single molecule to cellular networks and organisms. The journal encourages the development of a new biology-driven physics based on the extraordinary and increasingly rich data arising in biology, and provides research directions for those involved in the creation of novel bio-engineered systems. Physical Biology will publish a stimulating combination of full length research articles, communications, perspectives, reviews and tutorials from a wide range of disciplines covering topics such as: Single-molecule studies and nanobiotechnology Molecular interactions and protein folding Charge transfer and photobiology Ion channels; structure, function and ion regulation Molecular motors and force generation Subcellular processes Biological networks and neural systems Modeling aspects of molecular and cell biology Cell-cell signaling and interaction Biological patterns and development Evolutionary processes Novel tools and methods in physical biology Experts in the areas encompassed by the journal's scope have been appointed to the Editorial Scientific Committee and the composition of the Committee will be updated regularly to reflect the developments in this new and exciting field. Physical Biology is free online to everyone in 2004; you are invited to take advantage of this offer by visiting the journal homepage at http://physbio.iop.org This special print edition of Physical Biology is a combination of issues 1 and 2 of this electronic-only journal and it brings together an impressive range of articles in the fields covered, including a popular

    Plagiarism Plagiarism is, we are pleased to observe, not a common occurrence in Physics in Medicine & Biology (PMB); however, like those responsible for all scientific journals, we are concerned about plagiarism, and very keen to prevent it. The Publications Committee of the International Organization of Medical Physics (IOMP) has prepared a generic editorial on plagiarism. The editorial is reproduced here (with permission of the IOMP), with slight modifications to enhance its relevance to the audience of PMB, along with our procedures for dealing with any cases of plagiarism should they ever arise. Plagiarism (from the Latin 'plagiare', 'to kidnap') is defined as 'the appropriation or imitation of the language, ideas, and thoughts of another author, and representation of them as one's original work' (the Random House Dictionary of the English Language—unabridged). Plagiarism is a serious breach of research ethics that, if committed intentionally, is considered research misconduct. Plagiarism in its most serious form is the passing off of all, or large sections, of another author's published paper as one's original work. If, following appropriate confidential investigation (see below), such a plagiarism is established, this will result in heavy sanctions including retraction of the article, up to a 5 year publication ban from PMB, and informing of employers and/or professional bodies (even after one offence). This may result in loss of research funding, loss of professional stature, and even termination of employment of the plagiarizing author(s). Plagiarism undermines the authenticity of research manuscripts and the journals in which they are published, and compromises the integrity of the scientific process and the public regard for science. Plagiarism violates the literary rights of the individuals who are plagiarized, and the property rights of copyright holders. Violation of these rights may result in legal action against the individual(s) committing

    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.

Above all the results should be sufficiently new and important to merit rapid publication as a Letter, which implies accelerated refereeing procedures. This should be made clear either in the body of the Letter, if appropriate, or with a supporting cover letter from the author on submission to the journal. Letters will have an upper limit of eight journal pages and, as an additional quality check, two referees instead of one will be used to review them. The Board will be asked to make a final publication decision in the event of two conflicting reports. With these measures in place it is hoped that the important new results will receive the exposure they deserve as a Letter. If you have any questions or comments on this or anything relating to J.

    COSIRES 2004 was the seventh conference in the series of international conferences on computer simulation of radiation effects in solids. This series started in 1992 in Berlin, Germany, and has since then been held biennially in Santa Barbara, USA; Guildford, UK; Okayama, Japan; State College, USA and Dresden, Germany. In 2004 we were pleased to host 104 persons in Helsinki. The strength of the conference series was reflected in that about half of the attendees were graduate students or young postdocs. The good attendance and success of the meeting was to a large extent made possible by generous financial support from the Academy of Finland, the University of Helsinki, the Vilho, Yrjö and Kalle Väisälä foundation and the Magnus Ehrnrooth foundation. I am very grateful for this support received, as well as the efforts put in for the meeting by the international advisory committee, program committee and most of all the local organizing committee. Without the help of all my 18 local co-organizers the meeting could not have ran as smoothly and pleasantly as it did.

    This proceeding gives a summary of the current status and open questions of the radio technique for cosmic-ray air showers, assuming that the reader is already familiar with the principles. It includes recent results of selected experiments not present at this conference, e.g., LOPES and TREND. Current radio arrays like AERA or Tunka-Rex have demonstrated that areas of several km2 can be instrumented for reasonable costs with antenna spacings of the order of 200m. For the energy of the primary particle such sparse antenna arrays can already compete in absolute accuracy with other precise techniques, like the detection of air-fluorescence or air-Cherenkov light. With further improvements in the antenna calibration, the radio detection might become even more accurate. For the atmospheric depth of the shower maximum, Xmax, currently only the dense array LOFAR features a precision similar to the fluorescence technique, but analysis methods for the radio measurement of Xmax are still under development. Moreover, the combination of radio and muon measurements is expected to increase the accuracy of the mass composition, and this around-the-clock recording is not limited to clear nights as are the light-detection methods. Consequently, radio antennas will be a valuable add-on for any air shower array targeting the energy range above 100 PeV.

    Human rights groups have traditionally monitored and publicized human rights abuses suffered mainly by men (e.g., torture, killings, and imprisonment) and have ignored abuses of women. Gender-sensitive research and women's groups have uncovered this oversight. Rape in the former Yugoslavia is now considered a war crime, requiring full investigation and punishment. Conflict and violence affect women in several ways related specifically to the gender division of rights, responsibilities, and roles. Class and ethnic differences conceal this gender related experience, however. Even in countries sympathetic to women's equality, women still are second class citizens. Women are always conscious of the ever-present threat or experience of physical and sexual violence, almost always inflicted by men. Perpetrators use violence to keep women down; to restrict opportunities for them to live, learn, work, and care a full human beings; to impede their potential to organize and demand their rights. Domestic violence against women occurs across all social groups, races, age groups, and religious and political persuasions. Violence against females begins before birth. Forced prostitution violates women's human rights. Patriarchy supports discriminatory treatment and backs violence as a legitimate means to preserve the status quo. Was has had a gender-related effect on women in Afghanistan, Chad, and Cambodia. The psychological and social impact of conflict (e.g., state-sponsored terrorism) on women is also examined. Physical ailments are often manifestations of psychological disorders. Common themes are women's increased vulnerability to rape and sexual abuse during conflict, rapid rise in the numbers of households dependent on women's labor, placing on them an excessive burden, and complete disruption of economic and social life. Further, this disruption provides opportunities for women to overcome some aspects of their traditional roles. More than 80% of the world's refugees are women, their dependent children, and the elderly. Women are becoming leaders in armed conflict.

    The IBA conference has taken place in different countries from all over the world. It started in the United States in 1973, and since then has been held biennially without interruption, becoming the reference meeting on ion beam analysis and related methods and techniques. In its 17th edition, two Spanish laboratories, one from the Universidad de Sevilla and one from the Universidad Autónoma de Madrid had the honour and responsibility of organizing the conference. These two laboratories are, so far, the only ones in the country equipped with accelerators dedicated to ion beam analysis; the Centro Nacional de Aceleradores (CNA) in Seville and the Centro de Micro-Análisis de Materiales (CMAM) in Madrid. We took up this task enthusiastically, conscious that Spain has only very recently been equipped with IBA techniques and that this event would highlight to the scientific community of our country the importance and involvement of IBA techniques in new scientific and technological developments. The conference was held at the Melia Sevilla Hotel in Seville, Spain from 26 June-1 July 2005. This special issue of Nuclear Instruments and Methods in Physics Research B contains the published proceedings of the conference.

    The Indo-German workshop on "Synthesis and modification of nano-structured materials by energetic ion beams" (a joint venture of Nuclear Science Centre, New Delhi (now renamed to Inter University Accelerator Centre, IUAC) and Stuttgart University), which was held at the auditorium of the "International Centre of Genetic Engineering and Biotechnology" in New Delhi, India, from 20th until 24th of February 2005, was dedicated to the unique capabilities of energetic ions as a powerful tool in nano-science and -technology, both for generating and processing of nano-structured materials. Ions in different energy regimes play a different role in the field of nano-structure creation. A unique feature of the energetic ion is that it can excite the solid quasi-instantaneously in a nano-scale volume to very high levels and create extreme conditions (high temperature, high pressure), well-localized both in space and time. By the energy dissipation into the cold ambient quenching rates of up to 1014 K/s may be achieved and structures and phases far away from equilibrium may be formed on a nanometer scale. The non-equilibrium conditions may further result in non-linear behavior and instabilities, which may drive self-assembly and nm-pattern formation on large areas. Hence, ion beams appear as an ideal tool for nano-technology. The aim of the Indo-German workshop was to summarize the on-going applications of ion beams in the nano-sciences and -technology in both countries and to explore further the perspectives of energetic ions for the preparation and processing of functional nano-structures, in order to initiate and strengthen common research in this field.

    The 9th edition of the International Conference on Radiation Effects on Semiconductor Materials, Detectors and Devices (RESMDD), held in Florence, at Dipartimento di Fisica ed Astronomia on October 9-12, 2012, was aimed at discussing frontier research activities in several application fields as in nuclear and particle physics, astrophysics, medical and solid-state physics. Main topics discussed in this conference are tracking performance of heavily irradiated silicon detectors, developments required for the luminosity upgrade of the Large Hadron Collider (HL-LHC), radiation effects on semiconductor materials for medical (radiotherapy dosimeters, imaging devices), astrophysics (UV, X- and γ-ray detectors) and environmental applications, microscopic defect analysis of irradiated semiconductor materials and related radiation hardening technologies. On the first day the conference hosted a short course intended to introduce fundamentals in the development of semiconductor detectors for medical applications to graduate and PhD students, post-docs and young researchers, both engineers and physicists. Directors of the School were Prof. Marta Bucciolini of the University of Florence and INFN, Italy and Dr. Carlo Civinini, INFN Firenze, Italy. Emphasis was placed on the underlying physical principles, instrument design, factors affecting performance, and applications in both the clinical and preclinical applications. The School was attended by nearly 40 students/ young researchers. We warmly thank the Directors for organizing this interesting event and the professors and researchers who gave lessons, for sharing their experience and knowledge with the students.

    The two articles in this issue of the European Physical Journal Special Topics cover topics in Econophysics and GPU computing in the last years. In the first article [1], the formation of market prices for financial assets is described which can be understood as superposition of individual actions of market participants, in which they provide cumulative supply and demand. This concept of macroscopic properties emerging from microscopic interactions among the various subcomponents of the overall system is also well-known in statistical physics. The distribution of price changes in financial markets is clearly non-Gaussian leading to distinct features of the price process, such as scaling behavior, non-trivial correlation functions and clustered volatility. This article focuses on the analysis of financial time series and their correlations. A method is used for quantifying pattern based correlations of a time series. With this methodology, evidence is found that typical behavioral patterns of financial market participants manifest over short time scales, i.e., that reactions to given price patterns are not entirely random, but that similar price patterns also cause similar reactions. Based on the investigation of the complex correlations in financial time series, the question arises, which properties change when switching from a positive trend to a negative trend. An empirical quantification by rescaling provides the result that new price extrema coincide with a significant increase in transaction volume and a significant decrease in the length of corresponding time intervals between transactions. These findings are independent of the time scale over 9 orders of magnitude, and they exhibit characteristics which one can also find in other complex systems in nature (and in physical systems in particular). These properties are independent of the markets analyzed. Trends that exist only for a few seconds show the same characteristics as trends on time scales of several months. Thus, it is possible to study financial bubbles and their collapses in more detail, because trend switching processes occur with higher frequency on small time scales. In addition, a Monte Carlo based simulation of financial markets is analyzed and extended in order to reproduce empirical features and to gain insight into their causes. These causes include both financial market microstructure and the risk aversion of market participants.

    Dear Readers, In no time, we are almost halfway through 2015. Currently many issues concern psychiatrists, and does not fill them with optimism: an uncertain future implementation of the National Mental Health Protection Programme, or the recent amendment of criminal law, entering into force on 01.07.2015, on the significant enlargement of implementation of treatment and precautionary measures in psychiatric institutions. Prof. J.K. Gierowski [1] wrote in Psychiatria Polska about the misunderstanding and even conflict in this matter, between politicians, lawyers and psychiatric community, almost one and a half year ago. Several tragic, dramatic events (German Wings plane crash, the recent murder in Tworki) creates a bad social attitude towards the mentally ill. Our environment does not remain indifferent and is actively involved in the discussion - it is expressed by Letters to Editor, written by Elwira Marszałkowska-Krześ and Andrzej Brodziak, published in the current issue of the magazine. We are all aware of our responsibility - on the one hand for a safe environment for patients while ensuring adequate treatment to the ill, and on the other for creating the image of psychiatry and psychiatrists [2, 3].

    More than 30 years of scientific endeavor have brought us from programming simple models to impressive simulations of dynamic systems. Lattice models like Potts, percolation, fuse, fiber bundle, and growth models, just to name a few, are the prototypes or godfathers of statistical mechanics. With the availability of more powerful tools it became possible to develop these models and apply them on complex topologies, finding important practical applications in socio-technological systems (e.g., opinion dynamics, traffic, communication networks) and to engineering problems (e.g., fracture phenomena, mass transport). In parallel, particle models evolved from a hand full of interacting discs to three dimensional multibillion particle simulations that successfully describe interesting fracture phenomena, granular flow, and even fluid flow for engineering applications. Prof. Dr. Hans Jürgen Herrmann has dedicated his professional life to this journey.

    Soft condensed matter is characterized by the weak interactions between polyatomic constituents, by important thermal fluctuation effects, by mechanical softness and by a rich range of behavioursDefinition taken from the introduction to "Phase Transitions in Soft Condensed Matter", edited by Tormod Riste and David Sherrington, Plenum Press, 1989 (New York), the proceedings of a NATO Advanced Study Institute held in Geilo, Norway in 1989. This may have been the first time the term "soft condensed matter" was used in an official capacity. http://www.softbio.ox.ac.uk/. Examples include complex liquids, colloids, granular materials, foams, polymers, gels and various biological materials. These materials thus share an important common feature in that predominant physical behaviors occur at an energy scale comparable with room temperature thermal energy.

    Magmatic degassing plays a key role in the dynamics of volcanic activity and also in contributing to the carbon, water and sulphur volatile cycles on Earth. Quantifying the fluxes of magmatic gas emitted from volcanoes is therefore of fundamental importance in Earth Science. This has been recognised since the beginning of modern volcanology, with initial measurements of volcanic SO2 flux being conducted with COrrelation SPECtrometer instruments from the late seventies. While COSPEC measurements continue today, they have been largely superseded by compact grating spectrometers, which were first introduced soon after the start of the 21st Century. Since 2006, a new approach to measuring fluxes has appeared, that of quantitative imaging of the SO2 slant column amount in a volcanic plume. Quantitative imaging of volcanic plumes has created new opportunities and challenges, and in April 2013 an ESF-funded MeMoVolC workshop was held, with the objectives of bringing together the main research groups, create a vibrant, interconnected, community, and examine the current state of the art of this new research frontier. This special issue of sixteen papers within the Journal of Volcanology and Geothermal Research is the direct result of the discussions, intercomparisons and results reported in that workshop. The papers report on the volcanological objectives of the plume imaging community, the state of the art of the technology used, intercomparisons, validations, novel methods and results from field applications. Quantitative plume imaging of volcanic plumes is achieved by using both infrared and ultraviolet wavelengths, with each wavelength offering a different trade-off of strengths and weaknesses, and the papers in this issue reflect this wavelength flexibility. Gas compositions can also be imaged, and this approach offers much promise in the quantification of chemical processing within plumes. One of the key advantages of the plume imaging approach is that we can achieve gas flux measurements at 1-10 Hz frequencies, allowing direct comparisons with geophysical measurements, opening new, interdisciplinary opportunities to deepen our understanding of volcanological processes. Several challenges still can be improved upon, such as dealing with light scattering issues and full automation of data processing. However, it is clear that quantitative plume imaging will have a lasting and profound impact on how volcano observatories operate, our ability to forecast and manage volcanic eruptions, our constraints of global volcanic gas fluxes, and on our understanding of magma dynamics.

    Science often develops most vigorously through challenging studies of extreme phenomena. Superheavy elements fall into such a category. What is the heaviest element that can exist in Nature? Driven by the continued search for an anticipated "island of stability" of superheavy atomic nuclei and the understanding of their underlying nuclear (in)stability and atomic structure hence chemical properties, the past decades have seen a tremendous progress in experimental ingenuity and theoretical methodology to study and characterize superheavy elements. Therefore, we are very grateful that the Nobel Foundation [1] approved and, jointly with the Knut and Alice Wallenberg Foundation [2], provided the financial resources to organize and conduct the Nobel Symposium NS160, entitled Chemistry and Physics of Heavy and Superheavy Elements. These symposia "are devoted to areas of science where breakthroughs are occurring or deal with other topics of primary cultural or social significance" [1]. About three symposia are held each year, roughly every fourth symposium promotes a topic in physics as primary research area, and from about every third symposium a contemporary Nobel Price is being awarded.

    Ground based radiation research facilities are indispensable for a better understanding of the biological principles governing the responses of living organisms to space radiation and for advancing our knowledge in space radiation dosimetry and protection. 2015 marked the 20th anniversary of the first acquisition of space radiation biology and physics data at the Alternating Gradient Synchrotron (AGS) at the Brookhaven National Laboratory (BNL) in Upton, New York. Use of the BNL AGS was the product of a collaborative agreement between NASA and BNL to promote the goals of NASA to "expand human presence in the solar system and to the surface of Mars and to advance exploration, science, innovation and benefits to humanity and international collaboration". This collaborative agreement signed on April 8th, 1994 built on previous work at the Lawrence Berkeley National Laboratory Bevalac and paved the way for the approval and construction of a dedicated space radiation laboratory at BNL, the NASA Space Radiation Laboratory (NSRL). In this volume we present three review articles: on the history of the creation of the NSRL, by Walter Schimmerling; on the physics-related research at the AGS and NSRL, by Jack Miller and Cary Zeitlin; and on the identification and evaluation of biomarkers for modeling cancer risk after exposure to space radiation, by Janice Pluth and her colleagues. It is the hope of the editors that our readers, and especially those relatively new to the field, will find these articles to be informative and interesting and that they will foster an appreciation of the importance of ground based radiation research in protecting the health of crew members as they venture out into the solar system in the coming decades.

    The Tenth International Conference on Accelerator Mass Spectrometry (AMS-10) was held from September 5-10 at the University of California, Berkeley campus. The conference attracted 305 attendees from 26 countries who gave 144 platform presentations and presented a total of 170 posters. The conference opened with a special tribute to the late Roy Middleton, which was followed by a companion session on 'ion sourcery'. A plenary talk by Wally Broecker on his '53 years in the Radiocarbon Trenches', provided thought-provoking challenges to commonly accepted paradigms. A workshop on issues in the estimation of isotopic ratios and evaluations of activities from AMS measurements preceded the conference and a workshop on AMS in low-dose bioscience concluded it. Conference attendees had ample opportunity to sample local sights and mid-week excursions to the Napa Valley wine region and the Monterey Bay Aquarium were well attended. The social highlight of the conference was a dinner cruise on San Francisco Bay aboard the San Francisco Belle, which toured the bay on a clear evening and afforded spectacular views of the city front as well as the Bay and Golden Gate bridges. The proceedings of AMS-10 contain 140 peer-reviewed papers that detail recent developments in AMS technology and a broad range of scientific applications. The editors worked to ensure that these contributions represent original research that has not been published elsewhere. We are grateful to the many outside reviewers who provided thoughtful consideration and suggestions in their reviews of these manuscripts. The staff of the Center for Accelerator Mass Spectrometry at the Lawrence Livermore National Laboratory wishes to thank the many members of the international AMS community in allowing us to organize this conference. We are particularly grateful to the University of California's Toxic Substances Research Program, which provided key assistance with conference administration.

    The Borborema Province is part of a large orogenic realm that extends from northeastern Brazil to western Africa in reconstructions of the supercontinent Pangea. As such, understanding its tectonic evolution is crucial to place constraints on the history of growth and amalgamation of West Gondwana. In 1995, a special issue of the Journal of South American Earth Sciences was dedicated to the Borborema Province (vol. 8, nos 8/9) and the current issue encompasses several papers that provide a state-of-the-art assessment of several themes pertaining to its geological evolution. These papers highlight the large increase in the geological knowledge of this region attained in the last 20 years. The papers collected in this special issue originate from talks presented at the 3rd Borborema Symposium, held together with the 25th Symposium of Geology of the Northeast at the city of Gravatá in November 2013. The symposia were sponsored by the northeastern branch of the Brazilian Geological Society.

    The 11th meeting of the 'Ionizing Radiation and Polymers' symposium, IRaP2014 was held in Jeju Island, Korea between October 5 and 9, 2014. The foundations of IRaP symposium were established more than 20 years ago, and over the years it has grown to be a well established and appreciated symposium in the field of ionizing radiation and polymers. The event was organized by the concerted efforts and generous contributions of Korean Ministry of Science ICT and Future Planning, Korean Atomic Energy Research Institute, Korean Society of Radiation Industry, Korea Nuclear International Cooperation Foundation and International Atomic Energy Agency, IAEA. Following the traditions of previous IRaP symposia, oral presentations were collected in daily single sessions throughout the week allowing the participants to listen to every talk. Like in previous symposia entire spectrum of the effects of ionizing radiation on polymers were elaborated by oral and poster presentations. The progress and new trends in radiation chemistry, physics and processing of polymers covering nanotechnology, nanocomposites, biopolymers, membranes, natural polymers, surface modification, lithography, medical applications, packaging materials, polymers used in NPP environments were presented and discussed. This list by no means includes all the subjects covered by the symposium and a quick look at the contents of this proceedings will reveal the titles of many interesting subjects. This is another unique aspect of IRaP symposia, one can hardly find a relatively small sized meeting including such a variety of subjects. The participants of the IRaP2014 were also fortunate to learn about the new developments on the hardware of new X-ray and E-beam devices.

    This will be a year of metamorphosis for Starlink with major hardware upgrades and the widespread adoption of the ADAM software environment. Most of the original VAXs will be replaced with MicroVAX 3500 based Local Area VAX Clusters (LAVCs); also disappearing from these sites will be the old ARGS as the Digisolve Ikon becomes the principal image display. This comes ten years after the idea of co-ordinating the computing activities of the UK astronomical community was first mooted. Those pre-natal days of Starlink are remembered by Professor Mike Disney in the article which follows. Many Starlink users will be surprised to learn that a centralised computing facility with only remote access or occasional visits for users was considered! (Actually the first machine, the RAL database/communictaiont MicroVAX, began operating a user service only this year.) It is instructive to look at some of the proposals for national data-analysis facilities which were forerunners of Starlink. For example, funding of £40,000 initially with £10,000 annually was requested for computer enhancements at RGO to provide a spectral reduction service. The hardware recommendation was based on a single Interdata 10 computer with a 64KByte memory and a total of 5MByte of disc! Once again, it is a pleasure to thank all the contributors to the Bulletin, and invite our readers to contribute to forthcoming editions.

    Physicists generally and our readers in particular are only too aware that the availability of scientific material on the Internet has both advantages and disadvantages. The ease with which a scientist can retrieve information from his/her office has greatly assisted the publication process since references, for example, can be searched for, checked for relevance or cross references with increasing ease. At the same time, however, it has become much easier to use materials without giving credit to the originators and this form of scientific misconduct is of growing concern to the publication process. With this in mind I would like to mention that the facility for retrieving information via the Internet is further developing so that major search engines like Google will be directly usable for retrieving, for example, a Physica Scripta article. Non-subscribers gaining access only to title and abstract whilst subscribers can access the full text in the same way as previously—through libraries and publishers. Physica Scripta has been in the vanguard of electronic development and has many thousands of accesses per day to its full on-line archive. These developments, together with some recent cases of scientific fraud, has led to an increased demand for guidelines for proper ethical conduct in the process of science publishing and, to this end, the International Union of Pure and Applied Physics, IUPAP, is working on a recommendation that I expect to be able to display here once adopted.

    The Lunar Reconnaissance Orbiter (LRO) mission has forever changed our understanding of the Moon, Earth's nearest neighbor in space. By returning a comprehensive data set focused on supporting the extension of a human presence in the Solar System, LRO helps identify and characterize sites with high scientific and exploration value, favorable terrain, and an environment suitable for supporting future lunar missions. As seen in this special issue, LRO data are invaluable for improving our knowledge of fundamental aspects of the Moon and the Solar System, and paving the way for a safe human and robotic return to the Moon.

    I have never seen an angrier nurse audience in my career. It was at the RCN's Congress this year. The anger was not, as might be imagined, expressed over one of the more contentious motions for debate. It occurred in a side room off the main corridor of the Old Swan Hotel in Harrogate, a setting sufficiently obscure for Agatha Christie to have hidden there for several weeks when there was a national search for her! The event was a meeting of senior nurses all involved with care in nursing homes. These are not happy times for such nurses. The money available for nursing home care is being ever further constrained by central government and many nursing homes are closing down, as their owners can no longer afford to subsidise public sector healthcare provision. But this was not the cause of the angst.

    The Ninth International Conference on Computer Simulation of Radiation Effects in Solids (COSIRES 2008) was hosted by Beihang University in Beijing, China from 12 to 17 October 2008. Started in 1992 in Berlin, Germany, this conference series has been held biennially in Santa Barbara, CA, USA (1994); Guildford, UK (1996); Okayama, Japan (1998); State College, PA, USA (2000); Dresden, Germany (2002); Helsinki Finland (2004); and Richland, WA USA (2006). The COSIRES conferences are the foremost international forum on the theory, development and application of advanced computer simulation methods and algorithms to achieve fundamental understanding and predictive modeling of the interaction of energetic particles and clusters with solids. As can be noticed in the proceedings of the COSIRES conferences, these computer simulation methods and algorithms have been proven to be very useful for the study of fundamental radiation effect processes, which are not easily accessible by experimental methods owing to small time and length scales. Moreover, with advance in computing power, they have remarkably been developed in the different scales ranging from meso to atomistic, and even down to electronic levels, as well as coupling of the different scales. They are now becoming increasingly applicable for materials processing and performance prediction in advance engineering and energy-production technologies.

    Fractional calculus, in allowing integrals and derivatives of any positive real order (the term "fractional" is kept only for historical reasons), can be considered a branch of mathematical analysis which deals with integro-differential equations where the integrals are of convolution type and exhibit (weakly singular) kernels of power-law type. It has a history of at least three hundred years because it can be dated back to the letter from G.W. Leibniz to G.A. de L'Hôpital and J. Wallis, dated 30 September 1695, in which the meaning of the one-half order derivative was first discussed and were made some remarks about its possibility. Subsequent mention of fractional derivatives was made, in some context or the other by L. Euler (1730), J.L. Lagrange (1772), P.S. Laplace (1812), S.F. Lacroix (1819), J.B.J. Fourier (1822), N.H. Abel (1823), J. Liouville (1832), B. Riemann (1847), H.L. Greer (1859), H. Holmgren (1865), A.K. Grünwald (1867), A.V. Letnikov (1868), N.Ya. Sonin (1869), H. Laurent (1884), P.A. Nekrassov (1888), A. Krug (1890), O. Heaviside (1892), S. Pincherle (1902), H. Weyl (1919), P. Lévy (1923), A. Marchaud (1927), H.T. Davis (1936), A. Zygmund (1945), M. Riesz (1949), W. Feller (1952), just to cite some relevant contributors up the mid of the last century, see e.g. [1,2]. Recently, a poster illustrating the major contributors during the period 1695-1970 has been published [3].

    The year 2015 will likely have a unique place in the history books for the optics and photonics community, since it is paired with various events that are exciting for this field. For one it is the 125th birthday of the Optical Society (OSA), and in addition, the United Nations declared 2015 to be the Year Of Light. The first special issue of this year is dedicated to the topic of "Emerging Materials on Nanophotonics". While the field of nanophotonics has seen tremendous momentum through the support of plasmonics, opto-mechanics, and quantum photonics, it often are both the breakthroughs and continuing developments of materials that bring enabling opportunities for this field. For instance, the area of 2D materials has grown out of its infancy being focused on Graphene into a crossdisciplinary subject area. Here, both scientific and engineering potential are seen in a) novel physical effects, b) higher functionality, and c) smaller form factors all found in one material option. Coincidentally, theUSNational Science Foundation recently held a path findingworkshop on 2D materials Beyond Graphene, and followed through with a dedicated two-year program to fund engineering innovations of the same. Here, the bandgap tunability of trimetal Dichalcogenides (TMD) has found to bear rich bandgap tunability via composition, alloying, and altering design options such as substrate choices or stress, thus providing a large variety of functions. In this context it is interesting to note, that with the many material choices for TMDs, the importance of targeted approaches towards accelerated material-to-marketwas raised in theMaterial Genome Initiative by the US White House. However, with the fundamental challenge of nanophotonics - weak interactions between light and matter - the choice of materials as both device building block and functionality delivery option needs to be synergistically considered. In this regard metal optics is seen as an emerging field that is able to contribute to this design evolution of devices and systems with ever growing constrains. However, materials with new functionalities and *Corresponding Author: Volker Sorger: E-mail: sorger@email.gwu.edu form factors allow utilizing field enhancement techniques in an unprecedented way. This, for instance, enables subwavelength scale photonic and opto-electronic devices with performance improvements such as utilized by the Purcell effect in light emitters, detectors, or electro-optic switching devices. On the other hand, certain novel materials are able to clearly outperform any existing option; for instance transparent-conductive-oxides (TCO) have been found to be able to alter its refractive index by unity. Lastly, with the maturing of silicon photonics as an on-chip optics platform, higher integration options are considered in this special issue; passive devices such as waveguides made out of the electro-optically active Lithium Niobate aid highfunctionality systems on-chip. However, these novel materials and subsequent devices and systems need to be compared and benchmarked in order to be a guide for the next phase of opto-electronic integration and other technologies as carried out by some contributions of this special issue.As the festivities around this Year Of Light continue, this special issue summarizes some of the interesting work around the emerging materials for nanophotonics. Concluding, I would like to thank for the input and help of the fellow Guest Editors, Jenifer Dionne, Alexandra Boltasseva, and Luke Sweatlock along with the Nanophotonics staff, Dennis Couwenberg and Tara Dorrian.

    As clinical dermatologists, we are all striving to achieve the highest possible accuracy in our clinical acumen and diagnostic skills. Over the past decade, one relatively simple advance, epiluminescence microscopy with the use of the dermatoscope, has significantly contributed to our diagnostic skills in the detection of benign versus pigmented lesions. In the paper by Kawabata and Tamaki, these authors delineate distinctive dermatoscopic features of acral lentiginous melanoma in situ, and contrast this with melanocytic nevi. The restructuring of healthcare delivery systems by third party payers and governmental programs is impacting on the pattern of our medical practices. In Canada, this has limited access to widespread use of techniques such as Mohs' micrographic surgery. The article by Arlette and colleagues has further supported the well-established studies indicating that Mohs' micrographic surgery for high-risk skin cancers has a dramatic benefit. Healthcare restructuring has also led to a decreased number of trainees in a number of subspecialties, including dermatology. This decrease in manpower has been an impetus to look at alternative forms of care for underserviced areas. Telemedicine, the use of telecommunications technology to provide healthcare services over a distance, has been examined as one attempt at solving this problem. In the Point-Counterpoint articles, we have two distinct views on the future of telemedicine as it applies to dermatology. Over the past decade, there have been dramatic advances in our understanding at a molecular nature of various disease processes. This rapid development has translated into a large number of therapies. Regulatory agencies such as the Food and Drug Administration in the United States, or the Health Protection Branch in Canada, are caught between demands to bring effective therapies to the market in an expedited fashion, and yet establish efficacy and maintain safety of new therapeutic entities. This occurs by a multistaged approval process. During the early phases, exposure is limited in order to accumulate preliminary data on pharmacology and toxicity. In the Critical Appraisal CME series, Muglia and DiGiovanna describe early testing processes in Phase 1 clinical trials. Calciphylaxis is a severe disease associated with calcification of the skin, subcutaneous tissue and potentially, internal organs. While the disease itself is relatively uncommon, the manifestations are quite distinctive. In this issue of the Journal, we have a review of calciphylaxis from Richard Worth, as well as a preamble by Dr. Goodall and a case report by Kalaaji et al. illustrating the consequences of this rare but distinctive entity.

    To begin, I would like to wish our readers, authors, referees and Board of Editors a successful and happy 2008 and thank them for their contributions to Nuclear Fusion in 2007. I took over the editorship of Nuclear Fusion in January, and the year has been one in which the community as a whole has been busier than ever with a variety of duties associated with the ITER project. It was with pride that we published the Progress in the ITER Physics Basis in the June issue of the journal (stacks.iop.org/NF/47/i=6). The task undertaken by the coordinators, authors and referees was a daunting one but one which led to an outstandingly successful issue. The response from readers has been phenomenal and there were in the region of 10 000 downloads of papers in the first month following publication. Looking to 2008 and beyond, the journal will endeavour to continue to support the work of the fusion community. Refereeing As we have done since January 2005, we would like to thank our top ten most loyal referees who have helped the journal with its double-referee peer-review procedure in the past year. At the Nuclear Fusion Editorial Office we are fully aware of the load we put on the shoulders of our referees. At the end of 2004 the Editorial Board decided that a gesture of gratitude should be made to our most loyal referees. We offer them a personal subscription to Nuclear Fusion with electronic access for one year, free of charge. To select the top referees we have adopted the criterion that a researcher should have acted as a referee or adjudicator for at least three different manuscripts during the period from summer 2006 to the end of 2007. We have excluded our Board members and those referees who were already listed in the top ten in the last two years. According to our records the following people met this criterion. Congratulations and many, many thanks! H.L. Berk (Texas University, USA) J.S. DeGrassie (GAT, USA) C. Deutsch (Paris University, France) N. Hayashi (JAEA

    In July 1956, 50 years ago, the first issue of Physics in Medicine and Biology (PMB) was published. It was subtitled The Journal of the Hospital Physicists' Association and published in association with the Philosophical Magazine by Taylor and Francis. Subscriptions were £1 per part or £3 10s for an annual subscription. The Editor, Professor J E Roberts, prefaced the first issue with a cautious editorial noting: The appearance of a new journal is usually greeted with mixed feelings by scientific workers, a common response being that there are far too many journals already. Justification for a new publication is only possible if there is a clearly defined gap in the publishing facilities available to workers in a particular scientific field.... Professor Roberts ended by seeking support from the scientific community for the new venture. He certainly got it! From a tentative few hundred pages in four issues a year for the first few years, the journal is now issued twice monthly with nearly 8000 pages expected in volume 51. In this anniversary issue we have invited some 28 senior authors to submit papers on a range of subjects spanning the discipline. We decided that to be an author one had to be old, but age was not to be the only criterion! Indeed readers will recognize all names as major contributors to both the development of medical physics and the success of PMB. Authors were not asked to write formal topical reviews of the state-of-the-art of the sub-disciplines which make up medical physics, but rather to present short historical reviews, didactic in style, perhaps highlighting the role of PMB in the development of their fields. Nevertheless, other than a page limit (which many subsequently ignored!) no formal format was imposed on authors, so what follows is a range of contributions from the almost conversational, personal statement to the more formal and familiar scientific paper. Whatever the writing style we are confident that readers will gain some

    Dear authors and reviewers of articles for Measurement Science and Technology, I would like to thank all those who have published papers with us in 2006, and special thanks go to those of you who have kindly reviewed articles for the journal this year. I would also like to take this opportunity to update you on some of the developments on the journal this year. As many of you are no doubt aware our impact factor (a measure of the average number of times recent papers are referred to by others) has remained above 1 for the second year in a row. This is often taken as an indication of the quality and relevance of recently published research, and although as readers we develop our own instinct for journals of high quality, it is gratifying as an Editor to see the data from an independent organization agreeing with my own assessment. This year we have welcomed several new faces to our Editorial Board and International Advisory Board. We are delighted to welcome Professor Hirofumi Yamada of the University of Kyoto as a representative from Japan. From China we have been joined by Professor Xuzong Chen of Peking University and Professor Zhiyi Wei of Chinese Academy of Sciences, Beijing. Professor Ivan Marusic from University of Minnesota and Dr Paul Williams of the National Institute of Standards and Technology in Boulder have joined as North American representatives. As usual you will be able to submit your articles through them or direct to the Editorial Office in Bristol, UK. As part of our ongoing initiative to give our authors' work the highest visibility, all articles are freely available online for 30 days from the date of publication, allowing all researchers to read and view the latest research as soon as it is published, and this year there have been many interesting articles to read! As regular readers are aware, Measurement Science and Technology publishes special issues and features, which highlight an area of current interest. This year's topics included

    Bibliometric mapping of scientific articles based on keywords and technical terms in abstracts is now frequently used to chart scientific fields. In contrast, no significant mapping has been applied to the full texts of non-specialist documents. Editorials in Nature and Science are such non-specialist documents, reflecting the views of the two most read scientific journals on science, technology and policy issues. We use the VOSviewer mapping software to chart the topics of these editorials. A term map and a document map are constructed and clusters are distinguished in both of them. The validity of the document clustering is verified by a manual analysis of a sample of the editorials. This analysis confirms the homogeneity of the clusters obtained by mapping and augments the latter with further detail. As a result, the analysis provides reliable information on the distribution of the editorials over topics, and on differences between the journals. The most striking difference is that Nature devotes more attention to internal science policy issues and Science more to the political influence of scientists.

    2010-07-01

    This editorial opens the second special section on physics competitions in European Journal of Physics. In the first section last year, we asked for feedback on the idea of such a section and on the content of the articles. We received no answer whatsoever, which can be interpreted in two ways: the section is not interesting enough to raise motivation for feedback, or the reader is satisfied. Having no indication which scenario is the correct one, we are optimistic and favour the second. The section at hand contains three articles. Again, as last year, the organizer of the annual Olympiad reports on tasks and outcomes of this competition. The Olympiad took place in Merida, Mexico, and was by far the largest event with 316 contestants from 68 countries. Again, the predominance of Asian/Chinese students was manifest, showing how serious the training is taken by both their authorities and students. Unfortunately, the winners of the last International Young Physicists' Tournament (IYPT), the team from Korea, did not accept the offer to report on their prize-winning contribution. We are thankful that two students from Austria, who achieved second place with their team, took over and reported on the task which they presented in the finals of the competition. It connects the fields of sport and physics and explains a special move in skateboarding. The third contribution introduces a different competition, 'International Conference of Young Scientists'. On one hand, as in the Olympiad, it addresses individuals, not teams. On the other, as in the IYPT, students have several months to prepare and also the quality of the presentation is an important element of the judgment. In fact, this competition comes closer to real scientific research compared to the other events. Finally and again, we hope that this section will serve several purposes: To show the competitions as a very important tool in the support of gifted students. To raise awareness amongst university teachers, and

    2009-01-01

    The end of 2008 cannot pass without remarking that the economic news has repeatedly strengthened the case for nuclear fusion; not perhaps to solve the immediate crises but to offer long-term security of energy supply. Although temporary, the passage of the price of oil through 100 per barrel is a portent of things to come and should bolster our collective determination to develop nuclear fusion into a viable energy source. It is with great pride, therefore, that I can highlight the contributions that the Nuclear Fusion journal has made to the research programme and the consolidation of its position as the lead journal in the field. Of course, the journal would be nothing without its authors and referees and I would like to pass on my sincere thanks to them all for their work in 2008 and look forward to a continuing, successful collaboration in 2009. Refereeing The Nuclear Fusion Editorial Office understands how much effort is required of our referees. The Editorial Board decided that an expression of thanks to our most loyal referees is appropriate and so, since January 2005, we have been offering the top ten most loyal referees over the past year a personal subscription to Nuclear Fusion with electronic access for one year, free of charge. To select the top referees we have adopted the criterion that a researcher should have acted as a referee or adjudicator for at least two different manuscripts during the period from November 2007 to November 2008 and provided particularly detailed advice to the authors. We have excluded our Board members and those referees who were already listed in the last four years. According to our records the following people met this criterion. Congratulations and many, many thanks! T. Hino (Hokkaido University, Japan) M. Sugihara (ITER Cadarache, France) M. Dreval (Saskatchewan University, Canada) M.

  15. EDITORIAL: Permanent revolution - or evolution?

    NASA Astrophysics Data System (ADS)

    Dobson, Ken

    1998-03-01

    Honorary Editor It was that temporary Bolshevik Leon Trotsky who developed the principle of `permanent revolution', a principle that perhaps characterizes the recent history of education in (south) Britain more than does, say, principles traditionally associated with the Conservative or Labour parties. As this editorial is being written, changes are being made to primary school education, and the long-awaited details of the post-Dearing reorganizing of post-16 education are yet to hit the overful bookshelves and filing cabinets of school heads and examination board officials. But something unique has happened recently which might have surprised even Trotsky. The Secretary of State for Education has set up targets for primary school pupils' attainment and threatened (or promised) to resign if they are not met within the lifetime of our newly elected parliament. Of course, if Mr Blunkett is still in a position to resign at that stage he will have been the longest serving Secretary of State since time immemorial. But we should not carp: this is truly a revolutionary idea. Not the promise to resign - although this idea is not so fashionable now as it once was. The revolutionary idea is that a major change to an educational process is actually being made that carries with it a predicted and testable outcome. By contrast, when school physics was refreshed a generation ago by the introduction of Nuffield courses at both pre- and post-16 stages, no `targets' were set. I and many other physics teachers certainly preferred teaching these to teaching their predecessor syllabuses, and might even dare to assert that the pupils liked them too. But we still don't really know whether or not they learned more - or even better - physics. Very little happened as far as the outside world was concerned: the usual fraction of students gave up physics at the usual ages, and those who were examined didn't really get a better reward for their more up-to-date and more enjoyably learned

  16. Editorial on Future Jet Technologies

    NASA Astrophysics Data System (ADS)

    Gal-Or, Benjamin

    2014-12-01

    The jet engine is the prime flight controller in post-stall flight domains where conventional flight control fails, or when the engine prevents catastrophes in training, combat, loss of all airframe hydraulics (the engine retains its own hydraulics), loss of one engine, pilot errors, icing on the wings, landing gear and runway issues in takeoff and landing and in bad-whether recoveries. The scientific term for this revolutionary technology is "jet-steering", and in engineering practice - "thrust vectoring", or "TV". Jet-Steering in advanced fighter aircraft designs is integrated with stealth technology. The resulting classified Thrust-Vectoring-Stealth ("TVS") technology has generated a second jet-revolution by which all Air-&-Sea-Propulsion Science and R&D are now being reassessed. Classified F-22, X-47B/C and RQ-180 TVS-vehicles stand at the front of this revolution. But recent transfers of such sensitive technologies to South Korea and Japan [1-5], have raised various fundamental issues that are evaluated by this editorial-review. One, and perhaps a key conclusion presented here, means that both South Korea and Japan may have missed one of their air-&-sea defenses: To develop and field low-cost unmanned fleets of jet-drones, some for use with expensive, TVS-fighter aircraft in highly congested areas. In turn, the U.S., EU, Russia and China, are currently developing such fleets at various TVS levels and sizes. China, for instance, operates at least 15,000 drones ("UAVs") by 2014 in the civilian sector alone. All Chinese drones have been developed by at least 230 developers/manufacturers [1-16]. Mobile telecommunication of safe links between flyers and combat drones ("UCAVs") at increasingly deep penetrations into remote, congested areas, can gradually be purchased-developed-deployed and then operated by extant cader of tens of thousands "National Champion Flyers" who have already mastered the operation of mini-drones in free-to-all sport clubs under national

I recommend setting up a free e-mail alert so that you can read them as soon as they are published! As many of you are already aware, our impact factor (a measure of the average number of times recent papers are referred to by others) has risen again to 1.297. This is often taken as an indication of the quality and relevance of recently published research, and although as readers we develop our own instinct for journals of high quality, it is gratifying as an Editor to see the data from an independent organization (Thomson ISI) agreeing with my own assessment. Of course the publication of high quality articles in the journal is dependent both on you the authors who trust us with the publication of your best work and on our referees and Editorial Board Members who we depend on to maintain the high standards you have grown to expect. I must also thank our referees for their rapid response when asked to review papers for Measurement Science and Technology. On average, authors receive a decision on their article in 45 days. Therefore I would like to end this message by saying thank you again to all those who have contributed to our success in the past year, and wish you all the best for a successful 2009!

  18. EDITORIAL: New developments for Nanotechnology

    NASA Astrophysics Data System (ADS)

    Welland, Mark

    2007-01-01

    In this first issue of Nanotechnology for 2007 the journal has taken another step forward in its extraordinary growth and development of the past 5 years. The reader will notice two important changes that have been introduced primarily in response to the exponential rise in submissions to the journal: the contents have been restructured into sections and publication will now be weekly. These latest changes, however, are not the only ones that have been made to the journal and its service to authors and readers. A modern journal has many tools at its disposal that journals of even 10 years ago simply did not. Electronic submission and refereeing, web-based publication, author services such as free electronic reprints and an email alerting service, to name but a few. Published by a learned society, Nanotechnology has constantly responded to the needs of authors and readers alike drawing upon the extensive experience and tools of IOP Publishing. Nanotechnology is of course an exploding field and it is therefore perhaps unsurprising to see a growth in the number of submissions to the journal. However, an inspection of the data surrounding submissions over the past 4 years reveals a disproportionate growth in the success of the journal itself. In 2002 there were 419 submitted papers of which 208 were accepted and published in 6 issues. In 2005 we received 75% more submissions over 2002, had a reduced acceptance rate of 44% and published 12 issues. 2006 showed, in just one year, a growth over 2005 of greater than 50% in the number of submissions. This growth of course does present challenges. The paper issues of the journal have been increasing in mass, hence a move to weekly publishing, and the sheer number of papers means that finding an article on a specific topic can be difficult for readers and authors, hence the move to sections. Sections will also help the Editorial Board in ensuring that the journal has a balanced portfolio of papers reflecting the broad

    Neural engineering has grown substantially in the last few years and it is time to review the progress of the first journal in this field. Journal of Neural Engineering (JNE) is a quarterly publication that started in 2004. The journal is now in its third volume and eleven issues, consisting of 114 articles in total, have been published since its launch. The editorial processing times have been kept to a minimum, the receipt to first decision time is 41 days, on average, and the time from receipt to publication has been maintained below three months. It is also worth noting that it is free to publish in Journal of Neural Engineering—there are no author fees—and once published the articles are free online for the first month. The journal has been listed in Pubmed® since 2005 and has been accepted by ISI® in 2006. Who is reading Journal of Neural Engineering? The number of readers of JNE has increased significantly from 8050 full-text downloads in 2004 to 14 900 in 2005 and the first seven months of 2006 have already seen 12 800 downloads. The top users in 2005 were the Microsoft Corporation, Stanford University and the University of Michigan. The list of top ten users also includes non-US institutions: University of Toronto, University of Tokyo, Hong Kong Polytechnic, National Library of China and University College London, reflecting the international flavor of the journal. What are the hot topics in neural engineering? Based on the number of downloads and citations for 2004-2005, the top three topics are: (1) Brain-computer interfaces (2) Visual prostheses (3) Neural modelling Several other topics such as microelectrode arrays, neural signal processing, neural dynamics and neural circuit engineering are also in the top ten. Where are Journal of Neural Engineering articles cited? JNE articles have reached a wide audience and have been cited in of some of the best journals in physiology and neuroscience such as Nature Neuroscience, Journal of Neuroscience

    yet more unknown persons. But we live in a democracy, and the new core will be put out for consultation. This will take place between November 1st and 20th, and so will be over, more or less, by the time you read this Editorial. Ordinary teachers of physics are unlikely to be asked for opinions. However, the Institute's informal rapid response team will do their best to represent the interests not only of its members but of the wider physics community. The question remains, however, as to why such rapid reactions are necessary. Surely now is the time to reflect upon the consequences of the rushed initiatives of the past eight years or so in education, and indeed undertake a professional, independent evaluation of them. But our rulers seem incapable of doing other than create crises, and then managing the crises they create by creating even more. There are of course alternatives to this, as could easily be discovered by looking north of Hadrian's Wall, where change is taking placed in a managed, courteous fashion, and where the numbers of students studying physics post-16 is gently increasing. The Scottish Office Education Department has recently taken part in an OECD study of curriculum innovation in 13 countries. The department reports some key findings in the Scottish initiative which are in fact common to all the successful initiatives reported [1, 2]. The message is clear: curriculum change will fail - either completely or at least in reaching the anticipated outcome fully - if certain requirements are not met. The most significant of these, reported in the OECD study, are: Teachers will respond to challenges to become involved in curriculum innovation and to acquire new skills and competences if they are given encouragement and reassurance that they will be well supported in their efforts. Innovation must be systemic, i.e. showing an awareness that many aspects of education are interrelated (so that a change in one affects others). Teacher involvement is vital

    Ioannidou, Effie; Rosania, Amy

    2015-01-01

    Introduction Each journal’s editorial and advisory board plays a critical role in resolving gender bias in the peer-review and publication process. Thus, this study aimed to quantify women’s participation in editorial and advisory boards of major dental journals. Gender data on editorial and advisory boards were extracted from major dental journals, which were then categorized by journal specialty focus. The gender of the editor-in-chief and associate editor-in-chief was noted to assess the effect of journal leadership on women’s participation in journal boards. For comparison purposes, data were also obtained regarding the percentage of women faculty for each dental specialty. Results Overall, in the major 69 dental journals, 14.8% of editorial board members were women. An one-way ANOVA analysis revealed statistically significant gender differences between journal specialty categories (p = 0.003) with some dental specialties’ journals demonstrating a relatively high participation of women as editorial board members. There was a significant positive correlation for various dental specialties between women’s representation in editorial and advisory boards and women in similar dental academic specialties (p = 0.02, r2 = 0.55). Furthermore, there was a positive correlation between the presence of women in journal editorial leadership and the percentage of women serving as advisory board members (p = 0.03). Our results confirmed that the under-representation of women on dental journal editorial boards was significantly different between dental science specialties. When there were more women in journal editorial leadership positions, there was a higher participation of women as editorial and advisory board members. Journals should increase the numbers of women on editorial boards in order to secure diversity, improve publication quality and recognize women’s contribution to dental science. PMID:25635691

A historical overview of almost 50 years of the journal is reported, with the temporal projection of their bibliometric indicators. Qualitative and quantitative parameters of its editorial profile and indexes are also reported. Budget constraints and the actions being taken to address them are discussed. The difficulty in allocating reviewers for manuscripts submitted to the editorial process is also discussed; an issue that affects scientific publication in many areas of knowledge. In particular, we sought to reflect on the proposal of measures to boost the editorial process by alleviating the shortage of reviewers and their possible harmful consequences for the editorial process.

    The last issue of Journal of Optics B: Quantum and Semiclassical Optics under my editorship has recently been published. During the last five years, since its change of title, the journal has significantly modified its targets. Starting from a balanced mix of quantum optics and semiclassical optics, new topics have been brought within the scope of the journal, such as atom optics, degenerate quantum gases, quantum computation and quantum information, representing the growing role played by lasers within our technologically oriented society. Furthermore, the journal has greatly expanded the number of Special Issues and has introduced PhD Tutorials. While many authors do not have time to invest in preparing review articles, we have found the review-style PhD Tutorials to be very popular. Looking back over the evolution of the journal, the most obvious criterion of its development, at least from the point of view of the prospective contributing author, has been the gratifying increase in the impact factor measured by ISI, reflecting the leading position of Journal of Optics B as a European journal devoted exclusively to optics research. It is most rewarding to report that the number of printed pages has increased by 77% since 1999 and by more than 20% in the last year, far above the target planned by the publisher. Furthermore, from an Editorial point of view, the high standing of the journal is demonstrated by the very high quality ratings given by referees to the top fraction of submitted manuscripts and by the large number of full text web downloads reported for those papers. Special Issues also attract high numbers of web downloads, demonstrating the special attention these issues attract within the scientific community. Such results have been achieved only through teamwork, and I wish to express my gratitude to all those who contributed to this result over the years: Françoise Chavel from the European Optical Society secretariat in Paris, John Haynes, Tom Spicer

    2009-12-01

    This study evaluates the editorial policies of a randomized sample of English language peer-reviewed journals that publish original research involving the use of animals. The aim is to identify whether journals have editorial policies relating to the use of animals in the research that they are prepared to publish and whether any policies are likely to promote animal welfare and dissemination of information on the 3Rs (reduction, refinement, replacement) within the scientific community. The results demonstrate that a significant proportion of journals publishing original research involving animals do not have any editorial policy relating to the use of animals. Of those journals that do have policies the majority simply request that the research be carried out in accordance with standard regulatory requirements. This paper aims to provide editors and publishers with the information they need to review their own editorial policies to ensure they are fulfilling their potential to promote animal welfare and dissemination of the 3Rs.

    Radiología is the official journal of the Spanish Society of Diagnostic Imaging. It aims to contribute to the education of Spanish-speaking radiologists and to disseminate radiological research and knowledge in Spanish. The journal has an Editorial Board organized into areas or sections, and material published in the journal is chosen and improved through peer review. This article discusses the model of the scientific journal Radiología and the characteristics of its Editorial Board, comparing Radiología with official general radiology journals of other scientific societies. Moreover, the details of the journal's editorial process are revealed, including the editorial circuit, the reviewers' work, and the technical aspects of the final edition process. Finally, the article lists qualitative and quantitative data about the material that Radiología receives and publishes.

    Pless, I B

    2014-07-01

    In 1989, long before this journal added injuries to its title, it published two papers on childhood injuries and I was asked to write an editorial for this occasion. I chose the title "Challenges for Injury Prevention: Two Neglected Aspects" because I thought the papers neglected to mention the inadequacy of injury statistics (at the time there were no emergency department data) and also failed to emphasize the public health importance of childhood injuries. It is instructive, therefore, to compare this issue's offerings with how matters stood nearly 25 years ago and see what progress we've made. Papers in this and the previous issue of this journal discuss bicycle safety in general and helmet use in particular. Although this is a somewhat narrow focus, it serves as one indicator of how the field has evolved and what remains to be done to improve both the science and policy in this domain.

Rather than wait to write an editorial on good research practices in response to a major incident, I thought it might be best to be proactive and address some of the trends we see in submissions to this peer reviewed journal and to offer some suggestions for improvement improving the level of scholarship in some – but by no means all – of the papers submitted.

    The use of integrated information systems for healthcare has been started more than a decade ago. In recent years, rapid advances in information integration methods have spurred tremendous growth in the use of integrated information systems in healthcare delivery. Various techniques have been used for probing such integrated systems. These techniques include service-oriented architecture (SOA), EAI, workflow management, grid computing, and others. Many applications require a combination of these techniques, which gives rise to the emergence of enterprise systems in healthcare. Development of the techniques originated from different disciplines has the potential to significantly improve the performance of enterprise systems in healthcare. This editorial paper briefly introduces the enterprise systems in the perspective of healthcare informatics.

  18. Editorial Independence in the Electronic Age: New Threats, Old Owners?

    PubMed Central

    Hoey, John

    2008-01-01

    Editorial independence is crucial for the intellectual life of a scientific journal. A journal exists only as an idea created by authors and readers, with some editorial orchestration. Editorial independence can be compromised by pressure put on editors by their owners–whether commercial publishers or professional organizations. Both types of owners rely heavily on income from paid advertising in their print journals. Yet, the massive expansion of journal readership that has resulted due to the development of the Web has effected a marked shift in the readership of the journal, both geographically and intellectually, producing a new community of users who see only electronic versions of the journal. Commercial pressures on owners to satisfy the interests of the (mainly national and professional) print readership conflict with the editorial independence needed to respond to the vast Web constituency. This is a major source for compromise of editorial independence. Reduction of commercial pressures by transferring editorial costs to authors and by other cost-reducing models are discussed in this article. PMID:22013360

    December 2003 marks the end of an era in the world of metrology with the retirement of Terry Quinn FRS, Director of the BIPM since 1988. Terry's contribution to the field of metrology has been long and distinguished, both as a physicist and administrator; a long list of awards and honours bears testimony to the fact. From the standpoint of physics, his contributions have been numerous and important: in the field of thermometry he pioneered the use of cryogenic radiometers, instruments that are now employed as standards by National Metrology Institutes (NMIs) worldwide; his experiments to measure the Newtonian gravitational constant, G, the least well known of the fundamental constants, are characterized by elegant techniques and novel approaches; and as an example from the field of mass measurement, a definitive experiment at the BIPM ruled out the existence of the so-called 'fifth force'. As Director of the BIPM, Terry Quinn has been the driving force behind many of the initiatives undertaken in metrology in recent years. As any delegate to conferences or meetings at the BIPM will testify, his knowledge and grasp of complex issues are formidable, abilities that are particularly demonstrated at meetings of the Conférence Générale des Poids et Mesures (CGPM), where many questions of a technical or diplomatic nature are often raised. The signing of the Mutual Recognition Agreement (MRA) at the CGPM in Paris in 1999 by the directors of the NMIs of the industrialized states of the world was largely due to his efforts. In paying tribute to Terry, it would be remiss not to mention the part played by his charming wife, Renée. She has graciously hosted innumerable functions at the Quinn home over these years and has always made visitors to the BIPM feel most welcome. On behalf of Metrologia, its readers and Editorial Board, I take this opportunity to wish the Quinns a long and happy retirement. At the same time our best wishes go to Terry's successor, Professor Andrew

    2005-12-01

    For the last 13 years, Measurement Science and Technology has awarded a Best Paper prize. The Editorial Board of the journal believes that such a prize is an opportunity to thank authors for submitting their work, and serves as an integral part of the on-going quality review of the journal. An Editorial Board working party, comprising Patrick Gill (Chairman), David Birch and Ralph Tatam undertook the task of selecting as Best Paper 2004 a single contributed paper describing new and significant work, well aligned with the measurement scope of the journal, and presented in clear and rigorous form. They received a number of recommendations from the Editorial and International Advisory Board Members, and they would like to record their thanks to the Members for these recommendations, as they form an all-important first stage in the assessment process. There were responses from some five Board Members. In total, there were 16 papers nominated, plus another six from the working party. All these papers had quality ratings of 2 or higher from the referees, and note was also taken of the total electronic accesses for those papers subsequently short-listed. Review Articles, and papers that included a Board Member as an author, were automatically excluded. From the submitted nominations and working party deliberations, a short list of two papers was drawn up. The winning paper was then selected on the totality of criteria. Thus the paper recommended by the working party for the MST Best Paper Award for 2004 is: 'Adsorptive pressure-sensitive coatings on porous anodised aluminium' by Masaharu Kameda, Norikazu Tezuka, Tomohiro Hangai, Keisuke Asai, Kazuyuki Nakakita and Yutaka Amao, 15 489-500 (2004) This paper describes a novel pressure sensor based on a luminescent coating applied to a porous anodized aluminium layer, with application to the measurement of fluctuating pressures on short timescales with high spatial resolution. The research has particular application to

    Special issue in honour of Jürgen Hafner On 30 September 2010, Jürgen Hafner, one of the most prominent and influential members within the solid state community, retired. His remarkably broad scientific oeuvre has made him one of the founding fathers of modern computational materials science: more than 600 scientific publications, numerous contributions to books, and a highly cited monograph, which has become a standard reference in the theory of metals, witness not only the remarkable productivity of Jürgen Hafner but also his impact in theoretical solid state physics. In an effort to duly acknowledge Jürgen Hafner's lasting impact in this field, a Festsymposium was held on 27-29 September 2010 at the Universität Wien. The organizers of this symposium (and authors of this editorial) are proud to say that a large number of highly renowned scientists in theoretical condensed matter theory—co-workers, friends and students—accepted the invitation to this celebration of Hafner's jubilee. Some of these speakers also followed our invitation to submit their contribution to this Festschrift, published in Journal of Physics: Condensed Matter, a journal which Jürgen Hafner served in 2000-2003 and 2003-2006 as a member of the Advisory Editorial Board and member of the Executive Board, respectively. In the subsequent article, Volker Heine, friend and co-worker of Jürgen Hafner over many decades, gives an account of Hafner's impact in the field of theoretical condensed matter physics.

    First, editorial commentary: editorial commentary may be educational and may be controversial, but above all else, authors come first. Second, The Spin Move: The Spin Move is effective, cost-effective, and ubiquitous because, while many techniques are specific to a single joint, The Spin Move can be performed as a part of any arthroscopic and related procedure. However, like many advanced procedures, The Spin Move, when poorly executed, entails substantial risk. Preoperative planning is essential, and The Spin Move must be reviewed by inexperienced practitioners, in detailed text, figures tables, and video, at www.arthroscopytechniques.org.

    It has been said that no life is completed the way one had planned for it, and mine is no exception to that rule so far. When I was graduating with a BSc I was convinced I'd be doing physics research for the rest of my life -- and when I was getting my PhD I was sure I'd be teaching high school physics and helping others learn for the foreseeable future. Yet, 9 years later, I am not doing either of these as a full time job, and I've changed my mind a couple more times as to what career path (and broader lifestyle) would work best for me. In the intervening years, I've learnt to embrace change as a tool for carving my own path, and to be wary of the certainties that can tie oneself to a ``safe'' but uninspiring future. I studied at the University of Thessaloniki, Greece, and at Royal Holloway University of London (BSc); also at the University of Illinois at Urbana-Champaign (MSc) and at Imperial College London (PhD). After my PhD (and the national military service in Greece), I taught at high-school level for a couple of years in Crete, Greece. At the same time, I was science editor for Crete University Press, Greece's major university press. From there, I jumped onto the APS editorial boat: First to PRB (2003), then to PRL (2007), where I am now an Assistant Editor. I also have an adjunct research position at Columbia University.

  15. Editorial Bias in Crowd-Sourced Political Information

    PubMed Central

    2015-01-01

    The Internet has dramatically expanded citizens’ access to and ability to engage with political information. On many websites, any user can contribute and edit “crowd-sourced” information about important political figures. One of the most prominent examples of crowd-sourced information on the Internet is Wikipedia, a free and open encyclopedia created and edited entirely by users, and one of the world’s most accessed websites. While previous studies of crowd-sourced information platforms have found them to be accurate, few have considered biases in what kinds of information are included. We report the results of four randomized field experiments that sought to explore what biases exist in the political articles of this collaborative website. By randomly assigning factually true but either positive or negative and cited or uncited information to the Wikipedia pages of U.S. senators, we uncover substantial evidence of an editorial bias toward positivity on Wikipedia: Negative facts are 36% more likely to be removed by Wikipedia editors than positive facts within 12 hours and 29% more likely within 3 days. Although citations substantially increase an edit’s survival time, the editorial bias toward positivity is not eliminated by inclusion of a citation. We replicate this study on the Wikipedia pages of deceased as well as recently retired but living senators and find no evidence of an editorial bias in either. Our results demonstrate that crowd-sourced information is subject to an editorial bias that favors the politically active. PMID:26331611

    Physics in Medicine and Biology (PMB) is a journal that originated in the UK but is now rightly regarded as one of the pre-eminent international journals for the publication of material coming within its remit. It is 50 years old and its maturity is an outcome of the consistent support of high performing authors, a supportive and professional publishing house, dedicated referees, many vigorous and conscientious editorial boards and the collective input of the 10 previous Editors as listed in his incoming editorial (January 2000 issue) by the retiring Editor, Professor Alun Beddoe. The scientific climate and it associated publication modus operandi in the 1950s was very different from that at the current time and the journal has evolved to reflect this. Hence today the scope of content is somewhat broader, the size of the journal is vastly greater, the whole publication process is slicker and more efficient and a paper in PMB is highly prized by its authors and those who look to quality factors and impact. The quality of the journal still relies on the voluntary labour and expertise of its busy international referees and Board members. For many years I have tried to place my own research material in PMB and encourage my teams to do likewise, not only acknowledging the prestige of the journal but also because of the extraordinarily fast turnaround time of all the processes without any loss of quality. This serves us very well and the publishing team are to be congratulated. Some things seem to change more slowly or not at all, however. The prediction, when I started my research career, that books and journals would be dinosaurs by now has manifestly not come true and, whilst most of us are addicted (and why not?) to the electronic ways of doing things that can be done by more traditional ways, PMB and a packet of reprints from time to time arriving by post still has a reassuring feel despite the fact that the papers have been `on-line' for a while before.

    It is my pleasure to address these few lines to you all on the occasion of the start of the 2008 volume of Journal of Micromechanics and Microengineering, the journal's eighteenth year, and my eleventh year of service as Editor-in-Chief. As in previous years, I would like to take the opportunity to reflect on the achievements of the past year. The number of submissions to the journal continues to grow, to almost 800 in 2007. Importantly, the journal's ISI® impact factor remains at a solid 2.321. This is an achievement we can all be proud of. In 2007, an incredible 350 000 papers were downloaded, which clearly reflects the visibility and appreciation of our research work. These excellent results are entirely due to the fact that more of you are choosing to submit your high-quality work to the journal, and because more of you are also choosing to cite recent papers published within the journal. I would like to take this opportunity to thank each one of you: readers, authors and referees alike. To cope with the steadily increasing number of incoming papers, the review process had to be expanded. In 2007, more than 700 experts selected from 35 countries agreed to our requests to referee. In the name of the entire team, I would like to express my thanks to all our referees for their careful and well constructed reports, which are of paramount importance in maintaining the quality standards of Journal of Micromechanics and Microengineering. The average time to produce an individual report is a mere 19 days, contributing towards a very favourable overall processing time which is an attractive feature of the journal. Of course all this would not be possible without the constant hard work of the publishing, production and marketing staff in Bristol. In the name of the Editorial Board, contributing authors and readers, I wish to thank them for their support. Finally, I believe we have established a clear and distinct profile in the broad spectrum of journals in our field

    When Professor Anders Bárány took over as the Executive Editor of Physica Scripta, in 1986, he talked of his trepidation at having to 'dress himself' in his predecessor's 'editorial coveralls'. At that time, they had been worn by Professor Nils Robert Nilsson, a major figure in the physics community, for almost 20 years. Just one year prior to this, Professor Roger Wäppling had been recruited to the position of Subeditor in conjunction with a decision to expand the number of contributions in the field of condensed matter physics, to turn it into one of the dominant subjects in the broad-based journal. Physica Scripta had already gained a reputation for being a high quality journal with wide coverage of both experimental and theoretical physics. Interestingly, in the mid 1980s, the number of papers submitted had been growing and an impressive 250 submissions per year had been attained, with all of the manuscripts being handled in-house. Not many miles away in the town of Uppsala, a group of English students was stepping off a train on a magnificent snowy day in January to embark on their final year projects. A couple of us enjoyed ourselves so much that we stayed on afterwards as PhD students, thereby encountering the mixed pleasure of studying physics in a second language for the first time. I used to copy the notes down meticulously in Swedish, then try to work backwards with a textbook to improve my language skills. One day, returning from a particularly incomprehensible lecture on solid state physics, I showed my roommates my notes and asked if they could please explain what the lecture had been about: 'I don't know', they replied, 'but this bit is about sheep!' Meanwhile, back at Physica Scripta, the journal continued to flourish: 400 submissions were received in 1996, and the march of progress was well underway. Manuscripts could now be sent in on disks and Physica Scripta was available on the World Wide Web. Roger was appointed to manage the journal and

    New policy concerning expanded European and non-European A&A memberships: It is now thirty-five years since the scientific journal Astronomy & Astrophysics (A&A) was founded by the merging of six national journals from four European nations, namely France, Germany, the Netherlands and Sweden; Belgium and the other Nordic countries, Denmark, Finland and Norway, also participated. They were subsequently joined by five other western European nations, namely Austria, Greece, Italy, Spain and Switzerland (Norway later withdrew). A&A has no international legal status as such but is represented by the European Southern Observatory (ESO), which also manages its financial transactions. In the early nineteen-nineties, A&A with great foresight took an important step - which the European Union would follow more than a decade later - by incorporating eastern European countries into its sponsoring membership: the Czech Republic, Hungary, Poland and the Slovak Republic; Estonia became a full member in 1998. A&A was now truly ``A European Journal", as then stated on the front cover. In the meantime, A&A grew in importance as a vehicle for world-wide dissemination of astronomical research and an ever-increasing number of high-quality papers began streaming into the A&A Editorial offices from non-European countries, as well as from other European non-member countries. It became obvious to us that A&A no longer was merely a European Journal and in 2001 we removed the ``A European Journal'' from the front cover. Eventually, some of these non-European countries began approaching us with queries about potential membership in A&A and in 2002 we admitted the first such country, Argentina, with an observer status. Meanwhile, the Board intensified its study of the financial and administrative consequences of a wider expansion including the admission of member countries beyond Europe - a special subcommittee was appointed.

    tuneable lasers, generally with the emphasis on understanding the underlying physics rather than accumulating data. He had a highly original mind, which showed both in his choice of research topics and in his method of approach. He did not follow fashion; his instinct for an interesting problem was at odds with the modem policy of direct funding and the identification of "growth areas". His applications for research grants were often unsuccessful, despite his high international standing and integrity. He was never interested in building up a large research team, and had comparatively few research students, but his enthusiasm and commitment to the quality of his science attracted a succession of overseas visitors to his laboratory. Following my own year at the Clarendon, and some subsequent visits both to Oxford and to Reading, there was a continuing strong association between the Clarendon and Otago Physics that continues until today. George Series was the William Evans Visiting Professor to Otago University in 1972. He never lost his interest in the fundamentals of physics inspired by his first researches into the structure of the hydrogen atom; he wrote on the Rydberg constant, the physics of spontaneous emission, and on the fine-structure constant α = e2/hc. He donated a garden seat to St Edmund Hall (Oxford), of which he was a Fellow. On it he placed a plaque* in recognition of the ubiquitous nature of this constant; it almost had magical significance for him. He served physics in many ways outside research. He was for a number of years the Editor of the European Journal of Physics and was also Editor of the Journal of Physics B: Atomic and Molecular Physics, He was also on the Editorial Board of a number of journals. He was elected to Fellowship of a number of physics societies. The Editorial Board of these Memorial Essays dedicate them to George's memory, and to his wife Annette and his family.

    of all journals specialising in superconductivity. Further improvements, implemented from this January issue onwards, include: The introduction of article numbering which will speed up the publication process. Papers in different issues can be published online as soon as they are ready, without having to wait for a whole issue or section to be allocated page numbers. This will improve submission to publication times. Bringing the journal into line with other IOP journals so that reports from two referees are required for each paper prior to an acceptance/rejection decision. Refreshing the design of SuST's cover, modernising the typography and creating a consistent look and feel across the range of journals. Naturally we have also been asking how SuST and IOP Publishing can help the superconductivity community meet the challenges of the future and maintain the broad international readership that supports SuST. Clearly a specialist journal like SuST has a very different role in our community from general science journals such as Science and Nature. However the superconductivity community would benefit if publication in SuST brought with it the prestige of a yet higher impact factor, comparable to the very best physics, chemistry and engineering journals. In this context, I have identified the following aims for the Editorial Board: To increase the impact factor of SuST; To broaden the scope and size of the journal by increasing its profile and publishing the best papers in superconductivity— both in basic science and in technology; To improve the refereeing process by eliminating the tail of low impact papers submitted to SuST and reducing the time from submission to online availability; To make SuST the natural place to publish invited papers from the best of the community's pure and applied conferences and workshops; To improve the effectiveness of the Editorial Board; To improve the services that IOP Publishing provides for the superconductivity community.

Message from the Editor, F.C.

    's tropical forests that can provide key consistency and prioritization for national-level efforts. Gibbs et al calculate a range of national-level forest carbon stock estimates that can be used immediately, and also review ground-based and remote sensing approaches to estimate national-level tropical carbon stocks with increased accuracy. These papers help illustrate that methodologies and tools are indeed available to estimate emissions from deforestation. Clearly, important technical challenges remain (e.g. quantifying degradation, assessing uncertainty, verification procedures, capacity building, and Landsat data continuity) but we now have a sufficient technical base to support REDD early actions and readiness mechanisms for building national monitoring systems. Thus, we enter the COP 13 in Bali, Indonesia with great hope for a more inclusive climate policy encompassing all countries and emissions sources from both land-use and energy sectors. Our understanding of tropical deforestation and carbon emissions is improving and with that, opportunities to conserve tropical forests and the host of ecosystem services they provide while also increasing revenue streams in developing countries through economic incentives to avoid deforestation and degradation.

  12. Gender Representation on Journal Editorial Boards in the Mathematical Sciences

    PubMed Central

    2016-01-01

    We study gender representation on the editorial boards of 435 journals in the mathematical sciences. Women are known to comprise approximately 15% of tenure-stream faculty positions in doctoral-granting mathematical sciences departments in the United States. Compared to this group, we find that 8.9% of the 13067 editorships in our study are held by women. We describe group variations within the editorships by identifying specific journals, subfields, publishers, and countries that significantly exceed or fall short of this average. To enable our study, we develop a semi-automated method for inferring gender that has an estimated accuracy of 97.5%. Our findings provide the first measure of gender distribution on editorial boards in the mathematical sciences, offer insights that suggest future studies in the mathematical sciences, and introduce new methods that enable large-scale studies of gender distribution in other fields.

    With attention turning to the nation's domestic problems and the 1992 presidential election coming up, the last quarter of 1991 saw a marked increase in the number of editorials and opinion pieces devoted to health care topics. Many newspapers and magazines targeted the broader--and thornier--issue of national health care reform, but narrower and no less critical issues also received play, including Medicaid underpayment, emergency department overcrowding and HIV testing for health care workers.

    upon genetic algorithms and its performance is demonstrated on the example of dense spectra of (complexed) aromatic species. Interaction potential surface calculations of rare gasses with halogens in van der Waals complexes are described by Delgado-Barrio and co-workers, and Tennyson discusses new theoretical techniques based on the use of the variational principle to guide the spectral assignment of complicated water spectra, e.g. at very high temperatures. Finally, Okumura and co-workers present NIR spectra of NO3 and in combination with new calculations these shed light on how to interpret vibronic couplings in this interesting system. The last section of this issue comprises fragmentation and photo-dissociation studies. Rubio-Lago et al discuss methods to produce high-density spin polarized hydrogen following photodissociation experiments. The photodissociation of HCl and Cl2 is taken as an example by Balint-Kurti et al to demonstrate how amplitudes and phases of the photofragmentation matrix elements are derived from experimental measurements. Directional dynamics in photodissociation processes and the derivation of molecular frame properties are discussed in detail by Van den Brom et al using laboratory oriented molecules. And the issue closes with a contribution by Chambreau et al on different reaction mechanisms in the photodissociation of formaldehyde into H2 and CO. Coming to the end of this editorial, we wish to thank all the authors who participated with their contributions in this issue. It shows what is possible nowadays in the field of molecular dynamics and where things are heading in the near future. We thank Physica Scripta for providing us with the platform for this Special Issue, and we wish you, dear reader, many new insights!

  6. [North-South relations in scientific publications: editorial racism?].

    PubMed

    Victora, Cesar G; Moreira, Carmen B

    2006-08-01

    The aim of the present study was to comment on the possible existence of editorial prejudice among the editors of scientific journals from Northern countries against Southern authors. We highlight that a study using bibliometric methods documented an important imbalance in terms of the international scientific production of health researchers from high-income countries (the "North") and those from low and middle-income countries (the "South"). In a survey of Brazilian researchers, three in every four blamed this imbalance, at least in part, on prejudice among international editors. This is supported by the fact that a very small percentage of editorial board members of international journals come from the South. Although prejudice can explain part of the imbalance, there are also specific measures that may increase the likelihood of a paper from the South being accepted in international journals. These include the need to invest in the quality of the written text, and to show empathy with editors and readers, emphasizing the contribution of the manuscript to the international literature. Finally, we discuss whether research carried out in the South should be published in national or international journals, and suggest that there are at least six dimensions to this choice. These include language and target audience; type of contribution to knowledge; generalizability; citation index; speed of publication; and open access. The rapid growth in the number of Brazilian contributions to the international health literature shows that editorial prejudice, although often present, can be effectively offset by research with solid methodology and good-quality presentation.

    I am honoured to take on the leadership of Plasma Sources Science and Technology (PSST) as the successor to Professor Mark J Kushner, with whom I have had the pleasure to work on the journal for many years. Under Mark's insightful and energetic leadership over the last six years, PSST has cemented its position as the journal of choice within its subject area and is now one of the most successful journals in the field. In this first issue of 2014, I would like to reflect on some of the events and achievements of 2013. At the start of the year the PSST Editorial Board, recognizing the vital importance of atomic, molecular and optical (AMO) data to low-temperature plasma physics, agreed that PSST would accept papers reporting such new data, generated through both experiment and theory. Jonathan Tennyson joined the Editorial Board to represent this area. In March Anne Bourdon joined the Associate Editor team and has since then played a key part in the journal's review process alongside our other Editors. During the autumn, PSST moved to a new editorial management system. In December Deborah O'Connell was awarded the 2013 Hershkowitz Early Career Award and Review and joins the Editorial Board as of 2014. I would also like to thank Miles Turner for his work in leading the drafting of a guide on the details necessary in the reporting of the results of computer simulations; the main conclusions of this report have been incorporated into the journal policy. Overall 2013 has been another successful year for PSST; paper submissions were up by 8% on the previous year and there was the highest ever number of downloads of PSST papers in one year. Another noteworthy feature of 2013 was the continuing improvement in publication times while maintaining our high standards for acceptance and providing expert feedback coupled with encouragement particularly to younger researchers and groups. Largely as a result of the hard work of our referees and Associate Editors, the average time

    Objective The goal of this research is to learn how the editorial staffs of bioinformatics and medical informatics journals provide support for cross-community exposure. Models such as co-citation and co-author analysis measure the relationships between researchers; but they do not capture how environments that support knowledge transfer across communities are organized. Methods In this paper, we propose a social network analysis model to study how editorial boards integrate researchers from disparate communities. We evaluate our model by building relational networks based on the editorial boards of approximately 40 journals that serve as research outlets in medical informatics and bioinformatics. We track the evolution of editorial relationships through a longitudinal investigation over the years 2000 through 2005. Results Our findings suggest that there are research journals that support the collocation of editorial board members from the bioinformatics and medical informatics communities. Network centrality metrics indicate that editorial board members are located in the intersection of the communities and that the number of individuals in the intersection is growing with time. Conclusions Social network analysis methods provide insight into the relationships between the medical informatics and bioinformatics communities. The number of editorial board members facilitating the publication intersection of the communities has grown, but the intersection remains dependent on a small group of individuals and fragile.

    Bhattacharya, P.

    2004-04-01

    On 1 January, 2004, I assumed the position of Editor-in-Chief of Journal of Physics D: Applied Physics. I will start by saying that I will do my best to justify the confidence of the journal management and publishing staff in my abilities. I was fortunate to have been able to work, as an Editorial Board member, with my predecessor, the previous Editor-in-Chief, Professor Allister Ferguson. Allister has provided a high degree of intellectual stewardship for the journal in the last five years. He has made the job appear a worthy challenge for me. I therefore take this opportunity to thank Allister on behalf of the Editorial Board and publishing staff of the journal. Several other factors contributed to my decision to accept this position. The first is the group of people who actually go about the business of publishing. The Senior Publisher, Nicola Gulley (and her predecessor Sophy Le Masurier); the Managing Editor, Jill Membrey; the Publishing Administrators, Nina Blakesley and Sarah Towell; the Production Editor, Katie Gerrard and their office staff form an amazing group and have managed to make the operation of the journal incredibly efficient. An index of this is the speed with which incoming manuscripts are processed. The average time between the receipt of a manuscript and its web publication, if accepted, is 130 days. This is three to five times shorter than for most other journals. A factor that contributes to this success is a responsive pool of referees that the publishing staff have as a valuable resource. Ultimately, the standard bearers of any journal are the referees. Therefore, a grateful `thank you' is due from all of us at J. Phys. D to all our referees, who diligently perform this honourable task. The Associate Editors of the journal, Professors Lawler, Margaritondo and O'Grady, also provide immense scientific leadership. They help in defining new directions for the journal and in the publishing process. Last, but not least, a remarkable asset of

I have been at Cornell University since 2002, spent four years as a Program Manager at the Defense Advanced Research Project Agency from 1998-2002, and before that seven years at the Department of Mechanical Engineering at Vanderbilt University in Nashville, Tennessee. I have served on the Editorial Advisory Board of Smart Materials and Structures (SMS) for the last six years. It is a humbling thing to be asked to take up the post of Editor-in-Chief in a field with so many talented researchers. I would like to say a heartfelt thanks to the members of the Editorial Board and IOP Publishing for their confidence in me. Most importantly, I would like to thank Professor Vijay Varadan of the University of Arkansas and Professor Richard Claus of Virginia Polytechnic Institute and State University for their efforts in launching the journal 16 years ago. They have been stewards, promoters and, especially Vijay, key to the operation and function of SMS for all these years, and our research community is indebted to them. Professors Varadan and Claus have dedicated their careers to the area of smart materials and structures and we are very grateful for their leadership, mentoring and contribution. SMS is a thriving journal offering papers on all technical areas concerned with smart materials, systems and structures from the micro- and nanoscale to the macroscale. The journal is undergoing some major changes, including the recent transferal of papers to IOP Publishing's peer-review management system. With this new system authors can expect fast publication times of around 4 or 5 months from submission, and excellent author service. In this world of ever changing technology, the Editorial Board and I aim to reduce the time to publication for researchers in this exciting area of science and engineering. I am in the process of

    The 21st century is an era of great challenge for humankind; we are combating terrorism, climate change, poverty, human rights issues and last but not least non-communicable diseases (NCDs). The burden of the latter has become so large that it is being recognized by world leaders globally as an area that it is in need of much greater attention. In light of this concern, the World Health Organization (WHO) dedicated this year's World Health Day (held on April 7, 2016) to raising international awareness on diabetes, the fastest growing NCD in the world. This editorial is an account of the macro politics in place for fighting diabetes, both internationally and nationally.

    The Life Sciences Bibliographic Data Base was created in 1981 and subsequently expanded. A systematic, professional system was developed to collect, organize, and disseminate information about scientific publications resulting from research. The data base consists of bibliographic information and hard copies of all research papers published by Life Sciences-supported investigators. Technical improvements were instituted in the database. To minimize costs, take advantage of advances in personal computer technology, and achieve maximum flexibility and control, the data base was transferred from the JSC computer to personal computers at George Washington University (GWU). GWU also performed a range of related activities such as conducting in-depth searches on a variety of subjects, retrieving scientific literature, preparing presentations, summarizing research progress, answering correspondence requiring reference support, and providing writing and editorial support.

    2009-11-01

    The use of sensor networks for healthcare, well-being, and working in extreme environments has long roots in the engineering sector in medicine and biology community. With the maturity of wireless sensor networks, body area networks (BANs), and wireless BANs (WBANs), recent efforts in promoting the concept of body sensor networks (BSNs) aim to move beyond sensor connectivity to adopt a system-level approach to address issues related to biosensor design, interfacing, and embodiment, as well as ultralow-power processing/communication, power scavenging, autonomic sensing, data mining, inferencing, and integrated wireless sensor microsystems. As a result, the system architecture based on WBAN and BSN is becoming a widely accepted method of organization for ambulatory and ubiquitous monitoring systems. This editorial paper presents a snapshot of the current research and emerging applications and addresses some of the challenges and implementation issues.

    Dear Colleagues and Friends,on behalf of the Publishers, the Editorial Office, and the Editors of physica status solidi we wish you all the best for the coming year 2006! It is our sincere hope that your personal and professional experience with our journal has been a positive one and that you will continue to choose physica status solidi for the publication of your scientific findings in solid state physics also in the future.In doing so, you will be in increasingly good company! As a matter of fact, 2005 has been a year of exceptional growth in the number of manuscripts submitted to physica status solidi . Thus, the number of Original Papers which have reached our Editorial Office in Berlin has increased by as much as 30% compared to the long term average over the last ten years. For the Rapid Research Letter section, the corresponding increase has been even more impressive: more than +100% just in the last two years. We view this development as a confirmation of our longstanding efforts to ensure a timely publication service of high scientific quality. One relevant indicator for the high scientific standards expected from articles which are submitted for publication in physica status solidi is the average acceptance rate, which currently is less than 40%. This rate has continuously decreased from a value of about 60% ten years ago and bears witness to our efforts to strive for quality rather than quantity.Also, physica status solidi has been able to continue its long tradition as a truly international journal, despite of the strong competition in an established field such as solid state physics. In 2005, submitted papers have originated almost equally from the Americas, Europe, and Asia, with a clearly growing contribution from China, India, and Japan.

    Dear Colleagues and Friends,on behalf of the Publishers, the Editorial Office, and the Editors of physica status solidi we wish you all the best for the coming year 2006! It is our sincere hope that your personal and professional experience with our journal has been a positive one and that you will continue to choose physica status solidi for the publication of your scientific findings in solid state physics also in the future.In doing so, you will be in increasingly good company! As a matter of fact, 2005 has been a year of exceptional growth in the number of manuscripts submitted to physica status solidi. Thus, the number of Original Papers which have reached our Editorial Office in Berlin has increased by as much as 30% compared to the long term average over the last ten years. For the Rapid Research Letter section, the corresponding increase has been even more impressive: more than +100% just in the last two years. We view this development as a confirmation of our longstanding efforts to ensure a timely publication service of high scientific quality. One relevant indicator for the high scientific standards expected from articles which are submitted for publication in physica status solidi is the average acceptance rate, which currently is less than 40%. This rate has continuously decreased from a value of about 60% ten years ago and bears witness to our efforts to strive for quality rather than quantity.Also, physica status solidi has been able to continue its long tradition as a truly international journal, despite of the strong competition in an established field such as solid state physics. In 2005, submitted papers have originated almost equally from the Americas, Europe, and Asia, with a clearly growing contribution from China, India, and Japan. We are actively working together with our international Editorial Boards and the Regional Editors to maintain a reasonable balance among papers from different parts of the world. The increasing international

    The 21st century is an era of great challenge for humankind; we are combating terrorism, climate change, poverty, human rights issues and last but not least non-communicable diseases (NCDs). The burden of the latter has become so large that it is being recognized by world leaders globally as an area that it is in need of much greater attention. In light of this concern, the World Health Organization (WHO) dedicated this year’s World Health Day (held on April 7, 2016) to raising international awareness on diabetes, the fastest growing NCD in the world. This editorial is an account of the macro politics in place for fighting diabetes, both internationally and nationally. PMID:27694647

    Conflicts of interest arising from ties between pharmaceutical industry and physicians are common and may bias research. The extent to which these ties exist among editorial board members of medical journals is not known. This study aims to determine the prevalence and financial magnitude of potential conflicts of interest among editorial board members of five leading spine journals. The editorial boards of: The Spine Journal; Spine; European Spine Journal; Journal of Neurosurgery: Spine; and Journal of Spinal Disorders & Techniques were extracted on January 2013 from the journals’ websites. Disclosure statements were retrieved from the 2013 disclosure index of the North American Spine Society; the program of the 20th International Meeting on Advanced Spine Techniques; the program of the 48th Annual Meeting of the Scoliosis Research Society; the program of the AOSpine global spine congress; the presentations of the 2013 Annual Eurospine meeting; and the disclosure index of the American Academy of Orthopaedic Surgeons. Names of the editorial board members were compared with the individuals who completed a disclosure for one of these indexes. Disclosures were extracted when full names matched. Two hundred and ten (29%) of the 716 identified editorial board members reported a potential conflict of interest and 154 (22%) reported nothing to disclose. The remaining 352 (49%) editorial board members had no disclosure statement listed for one of the indexes. Eighty-nine (42%) of the 210 editorial board members with a potential conflict of interest reported a financial relationship of more than $10,000 during the prior year. This finding confirms that potential conflicts of interest exist in editorial boards which might influence the peer review process and can result in bias. Academia and medical journals in particular should be aware of this and strive to improve transparency of the review process. We emphasize recommendations that contribute to achieving this goal

    A blood pressure survey was carried out in 1976 in the city of Nuevo Laredo, Mexico, which involved 6,351 persons 30-69 years old. The study sample was recruited so as to represent an approximation of the overall distribution of occupational classes in the urban population. Members of the population sample were relatively young and of low educational attainment. To the extent that comparisons among surveys are feasible, mean blood pressure levels and hypertension rates were roughly comparable to those found in the white population of the United States. Although no firm conclusions can be drawn from the survey, a trend toward somewhat higher hypertension rates within the professional and managerial class was observed in some age groups in Laredo.

    Physica status solidi was founded in 1961 by a number of eminent solid state physicists as an attempt to overcome the iron curtain, which then separated East and West, at least in the field of science. Since that time our world has changed quite a bit, and so have the boundary conditions of science publishing. However, one thing has not changed: then as now, the general policy and development of a respectable scientific journal should be determined by a board of independent scientists, who volunteer to assume responsibility for the scientific content of the journal, to assure a fair and critical peer review process for all submitted manuscripts, and, in cases of conflict, to finally decide which papers will be published and which will not.As a matter of fact, an international Board of Editors which consists of scientists coming from different countries and continents, with a good reputation in their respective community, and without any conflict of interest with the Publisher of the journal is, in my opinion, these days more important than ever. As our daily scientific work becomes increasingly specialized, but at the same time also increasingly interdisciplinary, we are more and more forced to trust the quality and reliability of published scientific results in the literature, without really having a chance to come to an independent opinion on our own. This is one of the reasons why the many recent cases of plagiarism, scientific misconduct, or outright fraud have caused such a high level of public awareness. It is quite clear that without a serious peer review there would be an even larger number of such cases in the literature, and that without the responsible action taken by concerned Journal Editors, many of the revealed cases probably would have remained under the carpet.It is, therefore, a particular pleasure for me to introduce to you on the following pages the current Editorial Board of physica status solidi (a) in the form of a brief curriculum vitae, a

    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.

    Despite women earning similar numbers of graduate degrees as men in STEM disciplines, they are underrepresented in upper level positions in both academia and industry. Editorial board memberships are an important example of such positions; membership is both a professional honor in recognition of achievement and an opportunity for professional advancement. We surveyed 10 highly regarded journals in environmental biology, natural resource management, and plant sciences to quantify the number of women on their editorial boards and in positions of editorial leadership (i.e., Associate Editors and Editors-in-Chief) from 1985 to 2013. We found that during this time period only 16% of subject editors were women, with more pronounced disparities in positions of editorial leadership. Although the trend was towards improvement over time, there was surprising variation between journals, including those with similar disciplinary foci. While demographic changes in academia may reduce these disparities over time, we argue journals should proactively strive for gender parity on their editorial boards. This will both increase the number of women afforded the opportunities and benefits that accompany board membership and increase the number of role models and potential mentors for early-career scientists and students.

  10. The Opinion Editorial: teaching physiology outside the box.

    2006-06-01

    Improving the public understanding of science is an important challenge for the future professional scientists who are our current undergraduates. In this paper, we present a conceptual model that explores the role of mass media as community gatekeepers of new scientific findings. This model frames the benefits for undergraduate science students to learn about media genres so that they can learn to communicate science more effectively to nonprofessional audiences. Informed by this Media Role model, we then detail a novel writing task for undergraduate physiology students, the Opinion Editorial (Op-Ed), and an accompanying Peer Review. The Op-Ed genre was directly taught to the students by a professional journalist. As an assessment task, students presented a recent, highly technical paper as an Op-Ed. This was assessed by both faculty members and peers using a detailed assessment rubric. Most students were able to replicate the features of Op-Eds and attained high grades on their writing tasks. Survey data from final-year physiology students (n = 230) were collected before and after the implementation of the Op-Ed/Peer Review. These indicated that most students were aware of the importance of scientists to effectively communicate their knowledge to nonprofessional audiences, that the Op-Ed writing task was challenging, and that they believed that their ability to write to nonprofessional audiences was improved after explicit teaching and feedback.

    This editorial reviews the background issues, the design, the key achievements, and the follow-up research generated as a result of the PhysioNet/Computing in Cardiology (CinC) 2014 Challenge, published in the concurrent special issue of Physiological Measurement. Our major focus was to accelerate the development and facilitate the comparison of robust methods for locating heart beats in long-term multi-channel recordings. A public (training) database consisting of 151,032 annotated beats was compiled from records that contained ECGs as well as pulsatile signals that directly reflect cardiac activity, and other signals that may have few or no observable markers of heart beats. A separate hidden test data set (consisting of 152,478 beats) is permanently stored at PhysioNet, and a public framework has been developed to provide researchers the ability to continue to automatically score and compare the performance of their algorithms. A scoring criteria based on the averaging of gross sensitivity, gross positive predictivity, average sensitivity, and average positive predictivity is proposed. The top three scores (as of March 2015) on the hidden test data set were 93.64%, 91.50%, and 90.70%. PMID:26217894

    With many new members joining the CG&A editorial board over the past year, and with a renewed commitment to not only document the state of the art in computer graphics research and applications but to anticipate and where possible foster future areas of scientific discourse and industrial practice, we asked editorial and advisory council members about where they see their fields of expertise going. The answers compiled here aren’t meant to be all encompassing or deterministic when it comes to the opportunities computer graphics and interactive visualization hold for the future. Instead, we aim to accomplish two things: give a more in-depth introduction of members of the editorial board to the CG&A readership and encourage cross-disciplinary discourse toward approaching, complementing, or disputing the visions laid out in this compilation.

    This special issue of Journal of Micromechanics and Microengineering is devoted to the 18th European Workshop on Micromechanics (MME 07), which took place at the University of Minho, Guimarães, Portugal from 16-18 September 2007. Since the first workshop at the University of Twente in 1989 the field of micromechanics has grown substantially and new fields have been added: optics, RF, biomedical, chemistry, and in recent years the emergence of nanotechnology. This year an extensive programme was scheduled with contributions from new materials research to new manufacturing techniques. In addition, the invited speakers presented a review of the state-of-the-art in several main trends in current research, with the focus on micro/nanosystems in the ICT Work Programme in EC FP7. As ever, the two day workshop was attended by delegates from all over Europe, the USA, Brazil, Egypt, Japan and Canada. A total of 96 papers were accepted for presentation and there were a further five keynote presentations. The workshop provides a forum for young researchers to learn about new experimental methods and to enhance their knowledge of the field. This special issue presents a selection of 17 of the best papers from the workshop. The papers highlight fluidic and optical devices, energy scavenging microsystems, neural probe arrays and microtechnology fabrication techniques. All the papers went through the regular reviewing procedure of IOP Publishing, and I am grateful to all the referees for their excellent work. I would also like to extend my thanks to Professor Robert Puers for advice on the final selection of papers and to Ian Forbes of IOP Publishing for managing the entire process. My thanks also go to the editorial staff of Journal of Micromechanics and Microengineering. I believe that this special issue will provide a good overview of the topics presented at the workshop and I hope you enjoy reading it.

    This year Nuclear Fusion celebrates its fiftieth anniversary. This has been marked by the January special edition, containing papers presented at the plenary and celebratory evening session of the 22nd Fusion Energy Conference at Geneva. These papers underline the enormous progress that has been made in the last 50 years both in experiment and theory. Whilst the technical challenges that we face are still formidable, they are largely concerned with engineering a fusion reactor rather than fundamental plasma physics. In my editorial of a year ago, I remarked on the price of oil and the incentive that it gives to develop nuclear fusion into a viable energy source. This last year, attention has shifted somewhat from the markets to the environment and the Copenhagen climate summit in particular. The timescale for action on the environment is much shorter than we can possibly match and so we can only play our part towards developing long term solutions. Our responsibility is to present a programme that has the clear goal in developing a sustainable source of energy and, as the next step, make an unambiguous success of ITER. The Nuclear Fusion journal has continued to make an important contribution to the research programme and has maintained its position as the leading journal in the field. The journal depends entirely on its authors and referees and so I would like to thank them all for their work in 2009 and look forward to a continuing, successful collaboration in 2010. Refereeing The Nuclear Fusion Editorial Office understands how much effort is required of our referees. The Editorial Board decided that an expression of thanks to our most loyal referees is appropriate and so, since January 2005, we have been offering the top ten most active referees over the past year a personal subscription to Nuclear Fusion with electronic access for one year, free of charge. This year, seven of the top referees have reviewed four or more manuscripts in the period November 2008 to

    This special cluster in Journal of Physics D: Applied Physics comprises papers submitted by participants at the 2006 conference of the Institute of Physics Dielectrics Group, held at the University of Leicester during 10-12 April 2006. The conference focused on the interaction of non-ionizing electromagnetic (EM) fields with biological materials at all scales (tissues down to molecules) and at all frequencies. The use of dielectric techniques and theories in biological studies and in the pharmaceutical and biotechnology industries is increasing, and we hope that this conference helped to facilitate this trend and to further an understanding of the value of dielectric studies in biology—both in science and in applications in industry and medicine. An important policy of the Dielectrics Group is to promote the multidisciplinary nature of dielectric studies, and so we welcomed and received papers and posters from biologists, chemists, engineers, industrialists, medical professionals and physicists in the biotechnology and health care fields. The programme comprised 32 oral presentations, including the keynote opening address `Bio-dielectrics and bio-impedance' by Dr Ø G Martinson of the University of Oslo, and 7 papers given by invited speakers. 27 high-quality posters were also exhibited. The Mansel Davies Award, for the best presentation by a young researcher under the age of 30, was bestowed on Mr Sun Tao from the University of Southampton. His work, describing time domain analysis applied to dielectric spectroscopy of single cells, forms the subject matter of the first paper in this cluster. The remaining papers are presented in order of the session themes, namely Dielectric Spectroscopy and Techniques, Theory and Modelling, and Electrokinetics. On behalf of the Dielectrics Group, I thank the authors for their contributions, and the Institute of Physics for excellent administrative and editorial assistance.

The latter symposium was a gathering of about 200 renowned researchers from 16 countries around the world. The conference consisted of 24 symposia, 5 keynote papers, 21 invited papers, 108 oral presentations and about 160 poster papers covering the frontier areas of materials science and technology of functional materials. They included topics such as energy storage materials, ferroelectric materials, ferromagnetic materials, ferroelectric thin films, applications of functional materials, nanofabrication, computational design, shape memory alloys, application of shape memory materials, ferroelectrics and thermoelectrics, advances in characterizations, magneto-optical materials, Zn and Ti oxides, synthesis of nanopowders and wires, and many other advanced functional materials. With the receipt of more than 396 abstracts, this conference was a gathering of great minds in one place to discuss the research frontiers and discoveries in functional materials. The Organizing Committee would like to express its sincere thanks to the members of the International Advisory Committee for their invaluable contributions to the symposium. The committee is also grateful for the generous support from the many sponsors. A word of sincere thanks needs to go to Professor Roger Wäppling, Editor-in-Chief and the editorial staff of IOP Publishing for the publication of selected papers in this special issue of Physica Scripta. Finally, our deepest gratitude should be directed to the National University of Singapore, Zhejiang University and the General Research Institute for Nonferrous Metals, People's Republic of China for, without their support, the conference would not have been a success.

    As usual, being an even year, the 23rd IAEA Fusion Energy Conference took place at Daejeon, Korea. The event was notable not just for the quality of the presentations but also for the spectacular opening ceremony, in the presence of the Prime Minister, Kim Hwang-sik. The Prime Minister affirmed the importance of research into fusion energy research and pledged support for ITER. Such political visibility is good news, of course, but it brings with it the obligation to perform. Fortunately, good performance was much in evidence in the papers presented at the conference, of which a significant proportion contain 'ITER' in the title. Given this importance of ITER and the undertaking by the Nuclear Fusion journal to publish papers associated with Fusion Energy Conference presentations, the Nuclear Fusion Editorial Board has decided to adopt a simplified journal scope that encompasses technology papers more naturally. The scope is available from http://iopscience.iop.org/0029-5515/page/Journal%20information but is reproduced here for clarity: Nuclear Fusion publishes articles making significant advances to the field of controlled thermonuclear fusion. The journal scope includes: the production, heating and confinement of high temperature plasmas; the physical properties of such plasmas; the experimental or theoretical methods of exploring or explaining them; fusion reactor physics; reactor concepts; fusion technologies. The key to scope acceptability is now '....significant advances....' rather than any particular area of controlled thermonuclear fusion research. It is hoped that this will make scope decisions easier for the Nuclear Fusion office, the referees and the Editor.The Nuclear Fusion journal has continued to make an important contribution to the research programme and has maintained its position as the leading journal in the field. This is underlined by the fact that Nuclear Fusion has received an impact factor of 4.270, as listed in ISI's 2009 Science Citation

    Journal editorials are an important medium for communicating information about medical innovations. Evaluative statements contained in editorials pertain to the innovation's technical merits, as well as its probable economic, social and political, and ethical consequences. This information will either promote or impede the subsequent diffusion of innovations. This paper analyzes the evaluative information contained in thirty editorials that pertain to the topic of computer-assisted decision making (CDM). Most editorials agree that CDM technology is effective and economical in performing routine clinical tasks; controversy surrounds the use of more sophisticated CDM systems for complex problem solving. A few editorials argue that the innovation should play an integral role in transforming the established health care system. Most, however, maintain that it can or should be accommodated within the existing health care framework. Finally, while few editorials discuss the ethical ramifications of CDM technology, those that do suggest that it will contribute to more humane health care. The editorial analysis suggests that CDM technology aimed at routine clinical task will experience rapid diffusion. In contrast, the diffusion of more sophisticated CDM systems will, in the foreseeable future, likely be sporadic at best.

    Abstract We compiled a check list of the herpetofauna of Nuevo León. We documented 132 species (23 amphibians, 109 reptiles), representing 30 families (11 amphibians, 19 reptiles) and 73 genera (17 amphibians, 56 reptiles). Only two species are endemic to Nuevo León. Nuevo León contains a relatively high richness of lizards in the genus Sceloporus. Overlap in the herpetofauna of Nuevo León and states it borders is fairly extensive. Of 130 native species, 102 are considered species of Least Concern in the IUCN red list, four are listed as Vulnerable, five are listed as Near Threatened, and four are listed as Endangered. According to SEMARNAT, 78 species are not of conservation concern, 25 are subject to Special Protection, 27 are Threatened, and none are listed as in Danger of Extinction. Given current threats to the herpetofauna, additional efforts to understand the ecology and status of populations in Nuevo León are needed. PMID:27408562

    In this paper, we undertake a data-driven theoretical investigation of editorial workflows. We analyse a dataset containing information about 58 papers submitted to the Biochemistry and Biotechnology section of the Journal of the Serbian Chemical Society. We separate the peer review process into stages that each paper has to go through and introduce the notion of completion rate - the probability that an invitation sent to a potential reviewer will result in a finished review. Using empirical transition probabilities and probability distributions of the duration of each stage we create a directed weighted network, the analysis of which allows us to obtain the theoretical probability distributions of review time for different classes of reviewers. These theoretical distributions underlie our numerical simulations of different editorial strategies. Through these simulations, we test the impact of some modifications of the editorial policy on the efficiency of the whole review process. We discover that the distribution of review time is similar for all classes of reviewers, and that the completion rate of reviewers known personally by the editor is very high, which means that they are much more likely to answer the invitation and finish the review than other reviewers. Thus, the completion rate is the key factor that determines the efficiency of each editorial policy. Our results may be of great importance for editors and act as a guide in determining the optimal number of reviewers.

  2. EDITORIAL: Celebrating one year of Environmental Research Letters

    NASA Astrophysics Data System (ADS)

    Kammen, Daniel M.

    2008-03-01

    The one-year anniversary is a critical milestone for a new journal. At that point there are enough articles published to begin to define the scope and readership, yet generally not enough of a track-record for the full community to regard the new entrant as a fixture and a source of 'must read' material. Environmental Research Letters (ERL) has set itself a particularly large and interesting challenge: to help connect the vast community of environmental researchers, practitioners, activists, and interested informed observers. ERL and its partner online resource base and community website, environmentalresearchweb, fills a major void: a single locus for rapid publication of peer-reviewed and highly interdisciplinary material spanning literally every aspect of environmental research and thought. The wide range of material that falls squarely into the purview of ERL—from restoration ecology to global change science and politics, to toxicology and environmental justice, to environmental and social impacts of energy conversion—illustrate just how diverse a 'community' we hope to serve. Thanks to an exceptional editorial staff and board, and a diverse range of fascinating contributed papers, ERL is off to a particularly fast start. ERL has both a small advisory board and a larger editorial board. The board serves several functions, beginning with the traditional one of taking the lead on reviews of papers in such a dizzying array of areas. This task alone is a challenge because of the commitment ERL has made to exceptionally rapid publication: a goal of 90 days from submission to online publication for accepted papers. This goal, which we have generally met, includes the publication of complementary (but not always complimentary) 500 1000 word commentaries on a number of papers. To accomplish this alone the editorial board, and the reviewers, have been heroic, and deserve a huge round of applause. IOP Publishing too, has been truly wonderful in making this happen

  3. EDITORIAL: Thank you and farewell from the Founding Editor

    Baskes, Mike

    2005-07-01

    I have been involved with Modelling and Simulation in Materials Science and Engineering (MSMSE) from the very beginning when it was merely an idea, over 14 years ago, to the current journal that is well supported by the community. During my time as Editor there have been many changes in the journal, including the introduction of electronic submissions, web-based services and free printed colour where it is essential to the article, as well as completely free colour online. The journal has seen excellent growth in the number and quality of submissions and the number of articles published continues to rise, enabling us to expand the journal to eight issues in 2005. Web accesses and downloads have greatly surpassed even my wildest dreams. In my opinion, the emergence of MSMSE as a top materials modelling journal has confirmed the vision of Institute of Physics Publishing (IOPP) and the Executive Board that this area of science and engineering was ripe for a specialized journal. I feel that, having seen the journal through the early years and watched it grow into a successful arena for multidisciplinary materials research, it is now an appropriate time for me to hand over the reins. The journal has a great foundation for future growth and development and is supported by an excellent Editorial Board, who have given me a great deal of help and advice over the years. I feel sure that they will continue to support the journal when Bill Curtin, Brown University, takes over on 1 July 2005. Bill has the diverse experience in modelling at the atomic, dislocation, and continuum levels to lead the journal to new heights. Finally I would like to thank all of the readers, authors and referees who have greatly contributed to MSMSE over the years. Thank you for your support and help, and I hope you will continue to support the journal. Last, but not least, I would like to thank the staff at IOPP. Without their expert assistance, the journal could not have been as successful as it is

    At the time of writing, the construction of ITER is making, quite literally, visible progress; buildings have gone up, the tokamak pit has been equipped with the seismic pads and pylons have been put in place for the high tension input to the power supplies. Most of the main procurement arrangements have been let and we will see an increasing volume of deliveries to the ITER site over the coming years. In addition, the National Ignition Facility has started full operation and will undoubtedly see important results coming from it in 2012. These projects are important reminders of what a monumental endeavour we are all engaged in and the potential of nuclear fusion to improve the long-term condition of the human race. We can be proud, therefore, that the Nuclear Fusion journal makes such an important contribution to controlled fusion programmes and is maintaining its position as the leading journal in the field. More than 350 articles are submitted each year from over 40 countries. Nuclear Fusion continues to be the most highly cited journal in the field, with an impact factor of 3.303, as listed in the ISI 2010 Science Citation Index. The journal depends on its authors and referees for its success and so I would like to thank them all for their hard work in 2011, which should maintain the level of readership and the citation indices for years to come. I sincerely hope that 2012 will be as good. Refereeing The Nuclear Fusion editorial office understands how much effort is required of our referees. The Editorial Board decided that an expression of thanks to our most loyal referees is appropriate and so, since January 2005, we have been offering the top ten most active referees over the past year a personal subscription to Nuclear Fusion with electronic access for one year, free of charge. This year, three of the top referees have reviewed five manuscripts in the period November 2010 to November 2011 and provided excellent advice to the authors. We have excluded our

    funded projects (always with international participation) in the United States, Russian Federation, China, European Union, Japan, and Canada have been mutually united to explore the scientifically significant Northern Eurasian region. NEESPI scientists have been quite productive during the past two years (2005 2006) publishing more than 200 books, book chapters, and papers in refereed journals. NEESPI sessions at international conferences are open to everyone who works on environmental and climate change problems in Northern Eurasia and the circumpolar boreal zone. This thematic issue brings together articles from the authors who presented their latest results at the Annual Fall American Geophysical Union Meeting in San Francisco (December 2006). The research letters in this issue are preceded by two editorial papers (Leptoukh et al and Sherstyukov et al) devoted to informational support of research in the NEESPI domain that is critical to the success of the Initiative. The following papers are quite diverse and are assembled into five groups devoted to studies of climate and hydrology, land cover and land use, the biogeochemical cycle and its feedbacks, the cryosphere, and human dimensions in the NEESPI domain and the circumpolar boreal zone.

    wide spectrum of technological areas, such as medical imaging, pharmaceutical industry, analytical instrumentation, aerospace, remote sensing, lidars and ladars, surveillance, national defense, corrosion imaging and monitoring, sub-terrestrial and marine imaging. The complexity of the involved imaging scenarios, and demanding design parameters such as speed, signal-to-noise ratio, high specificity, high contrast and spatial resolution, high-scatter rejection, complex background and harsh environment, necessitate the development of a multifunctional, scalable and efficient imaging suite of sensors, solutions driven by innovation, operating on diverse detection and imaging principles. Finally, pattern recognition and image processing algorithms can significantly contribute to enhanced detection and imaging, including object classification, clustering, feature selection, texture analysis, segmentation, image compression and color representation under complex imaging scenarios, with applications in medical imaging, remote sensing, aerospace, radars, defense and homeland security. We feel confident that the exciting new contributions of this special feature on Imaging Systems and Techniques will appeal to the technical community. We would like to thank all authors as well as all anonymous reviewers and the MST Editorial Board, Publisher and staff for their tremendous efforts and invaluable support to enhance the quality of this significant endeavor.

    compromises. The exergy approach used by Srinivasagupta and Kardos to evaluate the ecological impact has shown great potential for measuring the effect of processes in the environment. The process they discuss is an environmentally friendly alternative to the standard pultrusion process. The sixth paper, by Chensong Dong and collaborators, focuses on modelling and optimizing dimensional variation in composites, and offers a good complement to Advani's papers. Papers seven by Lilly et al, and eight by Lyytikainen et al, focus on thermoplastic moulding. The last paper, by Chen et al, discusses the modelling of a technology that has the potential to be the environmentally friendly alternative to painting. I would like to thank Dr Mauricio Cabrera Rios, who obtained his PhD under my supervision and is now a professor at the Universidad Autonoma de Nuevo Leon, Mexico, for his help in coordinating the paper reviews. Also, the willingness of the authors to go through several review iterations where needed is greatly appreciated. Finally I would like to thank Ms Judith Adams (editor), without whose help this issue would not have been possible. She was instrumental in securing some papers and in obtaining the proper evaluations of others.

  14. Images of cloning and stem cell research in editorial cartoons in the United States.

    PubMed

    Giarelli, Ellen

    2006-01-01

    Through semiotic analysis of manifest and latent meanings in editorial cartoons, the author uncovers how cloning and stem cell research are represented in a popular mass medium. She identified 86 editorial cartoons published in the United States between 2001 and 2004 that referred to cloning and 20 that referred to stem cell research. Cartoonists portrayed people individually 224 times and 4 times in groups of more than 10. Men were portrayed in 64% of cartoons. Stem cell research was depicted as having a potential positive value, and cloning was depicted negatively. Some major messages are that cloning will lead to the mass production of evil, cloning creates monsters, and politics will influence who or what will be cloned. Analyzing popular images can allow access to public understanding about genetic technology and evaluation of public beliefs, preconceptions, and expectations as the public is educated on the use and value of services.

    This editorial presents the book as a continuation, with more emphasis on people, of the earlier prize-winning series "Organizations and Strategies in Astronomy (OSA)", the seven volumes of which described how astronomy research lives: how it is planned, funded and organized, how it interacts with other disciplines and the rest of the world, how it communicates, etc. All those books are a unique medium for scientists and non-scientists (sometimes from outside astronomy) to describe their experience, often for the first time at such a level, on non-purely scientific matters, many of them of fundamental importance for the efficient conduct astronomy-related activities. The editorial tackles also issues regarding ethics and management of people, stressing the need for managers with ad hoc training and a long-term vision of the role of astronomers towards the society at large.

    laboratory but also in the publication of scientific papers. We do, therefore, need a new journal that provides a platform for this emerging interdisciplinary field of neural engineering where neuroscientists, neurobiologists and engineers can publish their work in one periodical that spans the disciplines. Journal of Neural Engineering will provide this platform. The new journal will publish full-length articles of the highest quality and importance in the field of neural engineering at the molecular, cellular and systems levels. The scope of Journal of Neural Engineering encompasses experimental, computational and theoretical aspects of neural interfacing, neuroelectronics, neuromechanical systems, neuroinformatics, neuroimaging, neural prostheses, artificial and biological neural circuits, neural control, neural tissue regeneration, neural signal processing, neural modeling and neuro-computation. The scope of the journal has both depth and breadth in areas relevant to the interface between neuroscience and engineering. There will be two Editors-in-Chief, with expertise covering both engineering and neuroscience. Experts in the areas encompassed by the journal's scope have been identified for the Editorial Board and the composition of the board will be continually updated to address the developments in this new and exciting field. The first issue of this new journal covers a variety of topics that combine neuroscience and engineering: mental state recognition from EEG signals, analysis of body motion in Parkinson's patients, non-linear dynamics of the respiratory system, automatic identification of saccade-related visual evoked potentials, multiple electrode stimulators, algorithms to estimate the causal relationship between brain sources, diffusion tensor imaging in the brain and phase synchronization of neural activity in vitro.

    reader requests rather than in bulk. As part of this transformation, Letters will be posted as they become ready, rather than waiting for an entire issue to ready. This allows us to shorten the lag between acceptance and publication. Both of these changes are meant to point the way for the main journal, which will adopt these measures in the near future if they prove successful and if the different nature of the main journal does not pose a problem for these changes. This has ramifications for ApJ Letters in regard to the ways that submitted content is measured. Criteria for Letters will continue to be scientific immediacy and brevity. However, with the emphasis on electronic ApJ Letters delivery, the traditional 4.00 printed page limit has become obsolete. We will instead impose a content-counting system that is intended to follow the spirit of the 4 page limit, while being more transparent to authors. A similar system will be implemented for page charges in the main journal if we move to a print-on-demand publishing model there as well. In the midst of such rapid evolution we must rely heavily on our readers and authors to let us know which changes are welcome and where problems have arisen. We hope that everyone feels free to write to us with their concerns.

  20. Editorial: The publication of geoscientific model developments v1.1

    NASA Astrophysics Data System (ADS)

    Executive Editors, GMD

    2015-10-01

    Version 1.0 of the editorial of the EGU (European Geosciences Union) journal, Geoscientific Model Development (GMD), was published in 2013. In that editorial an assessment was made of the progress the journal had made since it started, and some revisions to the editorial policy were introduced. After 2 years of experience with this revised editorial policy there are a few required updates, refinements and clarifications, so here we present version 1.1 of the editorial. The most significant amendments relate to the peer-review criteria as presented in the Framework for GMD manuscript types, which is published as an appendix to this paper and also available on the GMD manuscript types webpage. We also slightly refine and update the Publication guide and introduce a self-contained code and data policy. The changes are summarised as follows: - All manuscript types are now required to include code or data availability paragraphs, and model code must always be made available (in the case of copyright or other legal issues, to the editor at a minimum). - The role of evaluation in GMD papers is clarified, and a separate evaluation paper type is introduced. Model descriptions must already be published or in peer review when separate evaluation papers are submitted. - Observationally derived data should normally be published in a data journal rather than in GMD. Syntheses of data which were specifically designed for tasks such as model boundary conditions or direct evaluation of model output may, however, be published in GMD. - GMD publishes a broad range of different kinds of models, and this fact is now more explicitly acknowledged. - The main changes to the Publication guide are the addition of guidelines for editors when assessing papers at the initial review stage. Before sending papers for peer review, editors are required to make sure that papers comply with the Framework for GMD paper types and to carefully consider the topic of plagiarism. - A new appendix, the GMD

Our goal to remain open-access will require that ERL secure a commitment of financial support—ideally from a foundation, individual, or a national or international research agency—so that the journal can publish in this fashion without the support of significant article publication charges.

    Scientists who are members of an editorial board have been accused of preferentially publishing their scientific work in the journal where they serve as editor. Reputation and academic standing do depend on an uninterrupted flow of published scientific work and the question does arise as to whether publication mainly occurs in the self-edited journal. This investigation was designed to determine whether editorial board members of five urological journals were more likely to publish their research reports in their own rather than in other journals. A retrospective analysis was conducted for all original reports published from 2001-2010 by 65 editorial board members nominated to the boards of five impact leading urologic journals in 2006. Publications before editorial board membership, 2001-2005, and publications within the period of time as an editorial board member, 2006-2010, were identified. The impact factors of the journals were also recorded over the time period 2001-2010 to see whether a change in impact factor correlated with publication locality. In the five journals as a whole, scientific work was not preferentially published in the journal in which the scientists served as editor. However, significant heterogeneity among the journals was evident. One journal showed a significant increase in the amount of published papers in the 'own' journal after assumption of editorship, three journals showed no change and one journal showed a highly significant decrease in publishing in the 'own' journal after assumption of editorship.

As Appendix II shows, those of interest to modern day plasma physicists are contained in volumes 3, 4 and 5. Postscript (added December 2008) Following the October 2008 online publication of our Editorial, we are grateful to Professor Manfred Hellberg of the University of KwaZulu-Natal (Durban, South Africa) for drawing our attention to a letter by H M Mott-Smith, one of Langmuir's co-workers, published in 1971 (Nature 233 219). In this letter Mott-Smith makes clear his recollection that Langmuir was struck by the analogy between 'the way blood plasma carries around red and white corpuscles and germs' and the way that the ' . . . "equilibrium" part of the discharge acted as a sort of sub-stratum carrying particles of special kinds, like high-velocity electrons from thermionic filaments, molecules and ions of gas impurities'. We thus conclude that this now settles the origin of the term.

  5. PSYCHOLOGY IN FRENCH ACADEMIC PUBLISHING IN THE LATE NINETEENTH CENTURY: ALFRED BINET, EDITORIAL DIRECTOR AT THE SCHLEICHER PUBLISHING HOUSE.

    Nicolas, Serge

    2015-01-01

    To date, historians of psychology have largely ignored the role of academic publishing and the editorial policies of the late nineteenth century. This paper analyzes the role played by academic publishing in the history of psychology in the specific case of France, a country that provides a very interesting and unique model. Up until the middle of the 1890s, there was no collection specifically dedicated to psychology. Alfred Binet was the first to found, in 1897, a collection of works specifically dedicated to scientific psychology. He chose to work with Reinwald-Schleicher. However, Binet was soon confronted with (1) competition from other French publishing houses, and (2) Schleicher's management and editorial problems that were to sound the death knell for Binet's emerging editorial ambitions. The intention of this paper is to encourage the efforts of the pioneers of modern psychology to have their work published and disseminated.

    Welcome to the first issue of the modified Fluid Dynamics Research (FDR) journal, which is now being published by IOP Publishing on behalf of the Japan Society of Fluid Mechanics. Since its launch in 1986, FDR has become a well-established international journal that publishes theoretical, numerical and experimental studies contributing to the fundamental understanding and application of fluid phenomena. It has also been an invaluable resource for physicists and researchers in engineering interested in problems relevant to the motion of fluids. From 2009, FDR will be edited by a new international Editorial Board, with the strong intention of establishing the journal further and bringing it to a wider audience. In this new-look FDR, which will be published six times per year, readers will find several special sections containing high quality invited reviews and papers written by leading researchers who have been selected by the international Editorial Board. This is in addition to the regular papers on a variety of topical subjects by active researchers in the field. As before, there are no publication charges for standard articles, and now article numbering has been adopted, enabling accepted papers to be published online more quickly, ahead of print publication. In order to maintain a balanced and up-to-date perspective, we welcome feedback from our readers regarding the content of the journal, as well as suggestions for topics to cover and areas to highlight. Finally, I would like to thank our authors, members of the international Editorial Board, and the staff at IOP Publishing for producing this first issue. We hope you will enjoy reading this renewed and exciting journal for the international fluid dynamics community.

    This Editorial describes the steps followed by a manuscript when it is submitted to Revista Médica de Chile: its reception, format checking as requested in Instructions to Authors, and the editors' decision whether it is considered suitable for the purposes of this journal or not; the selection of peer reviewers, a direct contact with them to ask for their willingness to review this particular manuscript; an analysis by the editors of the reviewers' criticisms leading them to the decision of whether to accept it in the current version, or to return it to the authors with a request to prepare a new corrected version, or a definitive rejection; the editors' review of a corrected version (that may require again the opinion of the external reviewers) and the final decision to accept it or not; printing of the manuscript, two successive galley proofs reviewed by authors and editors; and the final printing of the journal with its simultaneous reproduction in the web page www.scielo.cl. Roughly 70% of the manuscripts are returned to the authors offering them the opportunity to resubmit a corrected version, 12% are definitively rejected and 20% are accepted in their first version. The mean time taken for an accepted manuscript since its first submission until it appears printed is currently 7.6 months. Having only part time editors and a time-limited secretarial staff efforts to shorten this time are difficult to implement, although electronic mail and fax are increasingly being used in this editorial process.

    2006-01-01

    During the recent 6 years, a growing number of manuscripts have been submitted annually to Revista Médica de Chile. In 2005 this number was 60% greater than in the year 2000. This determined an increased workload in the editorial handling of manuscripts and in the number of external peer reviewers, who were over 400 participants during 2004, each one reviewing from one to five manuscripts in that year. An increasing use of the electronic mail helps to communicate editors with reviewers and authors. However, there is yet no availability of a software in Spanish to handle all communications in the editorial process in this language. The number of pages per issue has been increased and authors have been requested to limit the extension of their manuscripts, in order to allow more accepted manuscripts to appear in a shorter period of time. At the present, an average of 8.9 months separates the date of submission to the date of publication, in those manuscripts that were accepted in revised version after external peer review. The increasing number of submissions and the fact that this journal ranks high among Chilean journals, in the number of visits to full-text articles in the web page www.scielo.cl, testify that in spite of the aforementioned limitations Revista Médica de Chile is well considered among authors and readers in Chile and other Spanish-speaking countries.

    We analyzed 121 articles published in this Journal in 1989. Papers were classified as "clinical experiences" (55%), "research articles" (31%), "public health" (10%) and "clinical laboratory" (4%). 79% of papers were elaborated in University institutions and 77% came from the area of Santiago. 23% of articles were published in the original version and 77% required rewriting by authors to comply with editorial board review. In each case, time between reception of the manuscript and acceptation for publication was 69 +/- 36 (SD) and 141 +/- 78 days, respectively. Reviewers used 35 +/- 19 days. Main observations from reviewers were: lengthy introduction (17%), unprecise statement of objective (16%), inadequate description of methods (17%) or of patient selection criteria (9%), inadequate discussion of results (19%) or unsupported conclusions (18%) and inappropriate statistical analysis (17%). The title was changed in order to make it more informative and shorter in 23%, tables were standardized in 17% and references in 24% of papers. Awareness of these findings may help authors improve their manuscripts and reduce editorial time.

  17. Editorial independence and the editor-owner relationship: good editors never die, they just cross the line.

    PubMed

    Lapeña, J F

    2009-12-01

    The concept of editorial freedom or independence is examined in the light of the editor-owner relationship. Like individual and national freedom or independence, it is a rhetorical concept whose realisation flows from internal achievement as much as it depends on external validation. This freedom entails roles and responsibilities embodied in specific codes of practice for editors, such as the guidelines espoused by the International Committee of Medical Journal Editors and the World Association of Medical Editors. The calling to embody these guidelines makes editing a vocation that demands isolation and distancing, separation and solitude. It involves bracketing one's biases, prejudgments and preconceptions. With such detachment comes real freedom; one that requires a moral fibre and trustworthiness that uphold truth and right, whether in full view of public scrutiny, or in the aloneness of private secrecy. The stereotypical tension between academic and commercial concerns highlights the editor-owner relationship, and bears directly on editorial independence. In practice, journal owners overstep their prerogatives. The absence of clear contracts defining editorial independence and the lack of established mechanisms governing the editor-owner relationship affect many small- to medium-sized journals in developing countries. Even large journals in developed and democratic nations or totalitarian states and societies are not spared. At the end of the day, editorial freedom exists only insofar as it is tolerated, or until editors cross the line.

  18. Medical Hypotheses 2006 impact factor rises to 1.3--a vindication of the 'editorial review' system for revolutionary science.

    PubMed

    Charlton, Bruce G

    2007-01-01

    The Thomson Scientific Impact Factor (IF) for Medical Hypotheses has risen to 1.299 for 2006. This means that the IF has more than doubled since 2004, when it stood at 0.607. Using Elsevier's Scopus database; in 2004 there were 437 citations to Medical Hypotheses papers published in the previous two years--by 2006 this had trebled to 1216 citations. Monthly internet usage of Medical Hypotheses run at an average of about 26000 papers downloaded per month. An IF of 1.3 means that Medical Hypotheses has now entered the mainstream level of 'respectable' medical journals, in terms of its usage by other scientists. This is particularly pleasing given the aim of the journal is to publish radical and speculative ideas. A healthy IF is important to Medical Hypotheses because the journal deploys a system of editorial review, rather than peer review, for evaluation and selection of papers. Editorial review involves selection of a journal's content primarily by an editor who has broad experience and competence in the field, assisted by a relatively small editorial advisory board. The great advantage of editorial review is that it is able, by policy, to favour the publication of revolutionary science. But since editorial review relies on hard-to-quantify and non-transparent individual judgments, it is important for its outcomes to be open to objective evaluations. Scientometric measures of usage such as citations, impact factors and downloads constitute objective evidence concerning a journal's usefulness. Since Medical Hypotheses is performing adequately by such criteria, this provides a powerful answer to those who fetishize peer review and regard any other system of evaluation as suspect. Journal review procedures are merely a means to the end, and the end is a journal that serves a useful function in the dynamic process of science. Medical Hypotheses can now claim to perform such a role.

  19. Rainfall thresholds for the initiation of shallow landslides in Nuevo Leon, Mexico.

    2014-12-01

    The influence of rainfall on the occurrence of landslides depends on many factors such as landslide dimensions, kinematics or material involved. It is widely recognized that shallow landslides are usually triggered by short intense storms. Nuevo Leon state located in northeast Mexico is highly prone to the occurrence of this kind of slope failures due to its geologic, geomorphologic, climatic attributes and location, being targeted by tropical cyclones during the Atlantic hurricane season. A database of rainfall events that have resulted in shallow landslides on the region was compiled; the data indicated that there is a coincidence between the occurrence of shallow landslides and extreme rainfall events. A threshold curve in the form of I= αD-β was established to describe the threshold in where I is the rainfall intensity by rainfall event in mm/day and D is the duration of rainfall event in days. Duration of the rainfall events that triggered shallow landslides ranged from 2 to 5 days, with maximum intensity of 236 mm/day and a minimum intensity of 57.7 mm/day. From the data analyzed we could obtain a regression value of I = 109.77D-1.76 and established a new minimum rainfall intensity-duration threshold for the initiation of rainfall-induced shallow landslides that can be used for the development of a early warning system in Nuevo Leon, Mexico

  20. Assessing biodiversity in Nuevo Leon, Mexico: Are nature reserves the answer?

    2004-01-01

    The Mexican state of Nuevo Leon, located in the northeastern portion of the country, currently has 26 state and three federal nature reserves covering approximately 4.5% of its land area. These reserves were established for a variety of reasons not necessarily related to conservation purposes. In 2000 in response to a growing concern about the lack of organized conservation reserve planning to protect the important biological and physical features of Mexico, the Mexican Commission for Knowledge and Use of Biodiversity proposed 12 new terrestrial reserves for Nuevo Leon. The new reserves, if established, would increase the proportion of protected lands in the state to almost 24% of the state's land area. We compiled a Geographic Information System (GIS) analysis using digital thematic maps of physical and ecological features to examine how well the existing and proposed reserves incorporated the major biological and physical features of the state. The existing reserves are located primarily in regions with elevations > 1,000-1,500 m, on less productive soils, and are dominated by pine and oak forest cover types. As a result, the state's dominant biotic region - low elevation coastal plain with xeric scrub vegetation - is disproportionately under represented in the current reserve system. The new reserves would expand the protection of biophysical resources throughout the state. However, the inclusion of important resources in the low elevation coastal lands would still be limited.

    Tungsten is one of the main candidate materials for plasma-facing components in future fusion power plants. The Fuego-Nuevo II, a plasma focus device, which can produce dense magnetized helium and deuterium plasmas, has been adapted to address plasma-facing materials questions. In this paper we present results of tungsten targets exposed to deuterium plasmas in the Fuego Nuevo II device, using different experimental conditions. The plasma generated and accelerated in the coaxial gun is expected to have, before the pinch, energies of the order of hundreds eV and velocities of the order of 40,000 m s-1. At the pinch, the ions are reported to have energies of the order of 1.5 keV at most. The samples, analysed with a scanning electron microscope (SEM) in cross section show a damage profile to depths of the order of 580 nm, which are larger than those expected for ions with 1.5 keV, and may be evidence of ion acceleration. An analysis with the SRIM (Stopping Range of Ions in Matter) package calculations is shown.

    2016-08-15

    While the concepts of both "sex" and "gender" are widely recognized as important considerations in health research, the presence of these and other key determinants of health in research findings remains quite variable in the published literature. In an effort to close this knowledge gap in relation to the implications of both sex and gender in the public health research evidence base, the Canadian Journal of Public Health (CJPH) has recently adopted an editorial policy requiring authors to ensure that their manuscripts speak to these concepts, where applicable. In keeping with the international trend in sex and gender reporting in health research, the aim of this policy shift is for CJPH to continue to advance excellence in the field of public health research, policy and practice in Canada and internationally.

  7. Misconduct, Marginality and Editorial Practices in Management, Business and Economics Journals

    PubMed Central

    2016-01-01

    Objectives The paper presents data on the two problems of misconduct and marginality in management, business and economics (MBE) journals and their practices to combat these problems. Design Data was collected in three phases. First, all publicly retracted papers in MBE journals were identified through keywords searches in 7 major databases (n = 1329 journals). Second, a focused survey was distributed to editors involved in such retractions (n = 64; response rate = 28%). Finally, a survey was administered to all active journals in the seven databases to collect data on editors’ perceptions and practices related to the two problems (n = 937, response rate = 31.8%). Frequency analyses, cross tabulations, and qualitative analyses of open answers were used to examine the data. Results 184 retracted papers in MBE journals were identified in 2005–2015 (no retraction was found before 2005). From 2005–2007 to 2012–2015, the number of retractions increased by a factor ten with an all-time high in 2015. The survey to journals with reported retractions illustrates how already a few cases of suspected misconduct put a strain on the editorial workload. The survey to all active journals revealed that 42% of the respondents had started to use software to screen all submitted papers, and that a majority recognized the problem of marginality, as indicated by salami-style submissions. According to some editors, reviewers easily spot such submissions whereas others argued that authors may submit thinly sliced papers in parallel to several journals, which means that this practice is only discovered post-publication. The survey question on ways to support creative contributions stimulated a rich response of ideas regarding editorial vision, engaged boards and developmental approaches. The study uses data from three specialized fields, but its findings may be highly relevant to many journals in the social sciences. PMID:27454761

    Paleohydrological data, sometimes called "proxy records," reveal features of hydrologic variability not amenable to study with short instrumental hydrologic time series. Included are low-frequency features at wavelengths longer than the instrumental record, as well as high-frequency features that might differ in statistical properties from those that happen to be sampled by the instrumental record. Advances in paleohydrological methods and the expanded field collections of paleohydrologic proxies worldwide enable the reconstruction of different components of the hydrologic cycle on various scales of time and space. Reducing uncertainty about the variability of hydrologic processes is a major goal of paleohydrologic studies. New methods and datasets will help achieve this goal. At the same time, it is important to assess and appreciate the strengths and weaknesses of the expanding network of available proxy records.

    This volume contains the papers presented at 8th International Symposium on Radiation from Relativistic Electrons in Periodic Structures (RREPS'09), which was held in Zvenigorod, Moscow Region, Russia, from 7 to 11 September 2009, organized jointly by National Research Nuclear University MEPhI (Moscow) and Tomsk Polytechnic University (Tomsk), Russia. University MEPhI (Moscow) and Tomsk Polytechnic University (Tomsk), Russia. RREPS was founded in September 1993 by an initiative of the Nuclear Physics Institute at Tomsk Polytechnic University, Russia, with the intention of strengthening basic and applied research focused on radiation from relativistic particles in natural and artificial periodic structures. Since then, the symposium has developed into a forum attracting scientists from different fields and from many countries all over the world. RREPS'09 followed previous successful series of biennial RREPS symposia at Tomsk (1993, 1995, 1997, 2003), Baikal Lake (1999), Aya Lake (Altai, Russia, 2001) and Czech Technical University in Prague (Czech Republic, 2007). Five NIMB topical issues (V 145 No 1-2, October 1998; V 173 No 1-2, January 2001; V 201(1) January 2003; V 227, Issues 1-2, January 2005; V 266, Issue 17, September 2008) have been published as outgrowth of these symposia. Traditionally, the RREPS program includes following topics: General Properties of Electromagnetic Radiation from Relativistic Particles Transition Radiation Parametric X- Radiation Diffraction Radiation and Smith-Purcell Effect Coherent Bremsstrahlung and Channeling Radiation Crystal- Assisted Processes Applications of Monochromatic X- and Gamma- Beams Produced at Electron Accelerators The present RREPS'09 Symposium was dedicated to the modern problems in radiation from relativistic electrons in crystals and other periodic structures, as well as to new applications of photon and electron beams. During the last few decades, electromagnetic radiation from relativistic particles, both in external fields and in matter, has always been an interesting field for investigation. Every kind of radiation reflects specific processes of fundamental atomic physics, classical or quantum electrodynamics and might have specific applications in accelerator physics (beam diagnostics), nuclear physics (hard photon sources), material science and medicine (X-Ray sources). Nowadays, electromagnetic radiation studies cover electron energies from a few MeV up to hundreds of GeV in many laboratories throughout the world. The goal is to study the physics of generation of various kinds of radiation and their interplay or combined effects and to find successful applications for them. New photon sources, which use new types of radiation at new accelerators (e.g. tabletop synchrotrons), may be considered complementary to conventional photon sources based on synchrotron radiation, undulator radiation and free electron lasers. We express our thanks to the members of the International Program Committee for their suggestions during the preparation of the scientific program of the workshop. We warmly thank the National Research Nuclear University MEPhI (Moscow) and the Tomsk Polytechnic University (Tomsk) for the financial and administrative support. We also acknowledge the valuable financial contributions by Russian Fund for Basic Research and "Dynasty" Foundation. Editors Mikhail N.

    This editorial presents the book as a continuation of the first volume, both OPSA volumes being themselves in the line, with more emphasis on people, of the earlier prize-winning series "Organizations and Strategies in Astronomy (OSA)", the seven volumes of which described how astronomy research lives: how it is planned, funded and organized, how it interacts with other disciplines and the rest of the world, how it communicates, etc. All those books are a unique medium for scientists and non-scientists (sometimes from outside astronomy) to describe their experience, often for the first time at such a level, on non-purely scientific matters, many of them of fundamental importance for the efficient conduct astronomy-related activities. The editorial tackles also issues regarding ethics and management of people, stressing the need for managers with ad hoc training and a long-term vision of the role of astronomers towards the society at large.

    Some international organizations established Maximum Residue Limits (MRLs) in food to protect human health. Mexico lacks regulations in this matter, affecting national and international trade from agroindustry. The aim of this study was to diagnose pesticide residues in oranges from Nuevo Leon, México, in citrus orchards. In May 2014, 100 orange fruit samples were taken randomly from orchards and subjected to analysis for 93 pesticides at residual level by GC/QQQ-MS and LCQ-TOF-MS. Results showed presence of 15 pesticide residues in the samples. The comparison of the residual levels of pesticides found in orange samples among the MRLs allowed by USA, EU and Japanese regulations demonstrated that all samples were below MRLs issued by USA and Japan. Some orange samples were above MRLs issued by the EU. This provides a basis to establish strategies in order to satisfy International Standards to protect human health and encourage Food Safety in Mexico.

    An ethnobotanical study in the Cumbres de Monterrey National Park (CMNP), Nuevo Leon, Mexico was conducted. In spite of the large area (1,773.7 km2), heterogeneous physiography, contrasting plant communities and high species diversity of the CMNP, very little was previously known about its useful plants. Based on 95 interviews with inhabitants of the region who were 35 years or older, we recorded ethnobotanical data of 240 species (comprising 170 genera and 69 botanical families), and 146 different uses. Most of the cited uses (98) were found to be medicinal ones. Background An ethnobotanical study in the Cumbres de Monterrey National Park (CMNP), Nuevo Leon, Mexico was conducted.

  19. Representations of people with HIV and hepatitis C in editorials of medical journals: discourses and interdiscursive relations.

    HIV and hepatitis C are blood-borne viruses that cause chronic diseases and affect (in parts of the developed world) predominantly groups that are marginalized and discriminated against: gay men and injecting drug users, respectively. This paper compares the representation of people with HIV and hepatitis C in editorials of medical journals between 1989 and 2001. Analysis is informed by critical discourse analysis and systemic functional linguistics. Hepatitis C editorials draw almost exclusively on the discourse of biomedicine, and patients are either absent or objects in medical procedures. In HIV editorials, a variety of other discourses are integrated into the discourse of biomedicine, thereby creating multidimensional representations of people with HIV as patients and agents in medical procedures, involved in decision making, affected by economic factors, social and cultural issues. The paper discusses the role of the gay community in discursive change and argues that discursive diversity in the representation of people infected with HIV and hepatitis C in medical journals is necessary for health policy, the professional development of healthcare providers, and media reporting to the general public.

    I would like to extend my warmest greetings to the readers and staff of Science and Technology of Advanced Materials (STAM), on the occasion of its 10th anniversary. Launched in 2000, STAM marks this year an important milestone in its history. This is a great occasion to celebrate. STAM was founded by Tsuyoshi Masumoto in collaboration with Teruo Kishi and Toyonobu Yoshida as a world-class resource for the materials science community. It was initially supported by several materials research societies and was published as a regular peer-reviewed journal. Significant changes occurred in 2008, when the National Institute for Materials Science (NIMS) became solely responsible for all the costs of maintaining the journal. STAM was transformed into an open-access journal published by NIMS in partnership with IOP Publishing. As a result, the publication charges were waived and the entire STAM content, including all back issues, became freely accessible through the IOP Publishing website. The transition has made STAM more competitive and successful in global publication communities, with innovative ideas and approaches. The journal has also changed its publication strategy, aiming to publish a limited number of high-quality articles covering the frontiers of materials science. Special emphasis has been placed on reviews and focus issues, providing recent summaries of hot materials science topics. Publication has become electronic only; however, selected issues are printed and freely distributed at major international scientific events. The Editorial Board has been expanded to include leading experts from all over the world and, together with the Editorial Office, the board members are doing their best to transform STAM into a leading materials science journal. These efforts are paying off, as shown by the rapidly increasing number of article downloads and citations in 2009. I believe that the STAM audience can not only deepen their knowledge in their own specialties but

    In the National Cancer Act of 1971, the Director of the National Cancer Institute (NCI) was given a mandate to "Collect, analyze, and disseminate all data useful in the prevention, diagnosis, and treatment of cancer, including the establishment of an International Cancer Research Data Bank (ICRDB) to collect, catalog, store, and disseminate insofar as feasible the results of cancer research undertaken in any country for the use of any person involved in cancer research in any country" (National Cancer Act of 1971, S 1828, 92nd Congress, 1st Sess (1971)). In subsequent legislation, the audience for NCI's information dissemination activities was expanded to include physicians and other healthcare professionals, patients and their families, and the general public, in addition to cancer researchers. The Institute's response to these legislative requirements was to create what is now known as the Physician Data Query (PDQ®) cancer information database. From its beginnings in 1977 as a database of NCI-sponsored cancer clinical trials, PDQ has grown to include extensive information about cancer treatment, screening, prevention, supportive and palliative care, genetics, drugs, and more. Herein, we describe the history, editorial processes, influence, and global reach of one component of the PDQ database, namely its evidence-based cancer information summaries for health professionals. These summaries are widely recognized as important cancer information and education resources, and they further serve as foundational documents for the development of other cancer information products by NCI and other organizations.

    Six million migrants from over 170 countries have resettled in Australia since 1945 ensuring religious diversity is now a hallmark of Australia's population. However, not all religious groups are perceived in the same way. In this paper, we explore how representational processes differentially essentialise religious groups, in particular how some groups are ascribed an underlying nature that irrevocably defines who they are and how they will behave, whilst other groups are conveyed merely as coherent entities with similarity in goals and structure. We elucidate this through an analysis of the depiction of religious markers in Australian Editorial political cartoons. We mirror the near-exclusive focus on the Muslim and Christian religions, in the religious cartoons we sampled, to present an analysis of 6 exemplar cartoons. Drawing from visual analysis techniques (van Leeuwen 2001) and social representations theory (Moscovici 1984) we highlight how essentialist perceptions of religious groups are unwittingly fostered in everyday media communications. We discuss the implications of our analysis for the transnationalisation of religion.

    The twenty-first century is certainly in progress by now, but hardly well underway. Therefore, I will take that modest elasticity in concept as a frame for this essay. This frame will serve as background for some of my hopes and gripes about contemporary psychology and mathematical psychology’s place therein. It will also act as platform for earnest, if wistful thoughts about what might have (and perhaps can still) aid us in forwarding our agenda and what I see as some of the promising avenues for the future. I loosely structure the essay into a section about mathematical psychology in the context of psychology at large and then a section devoted to prospects within mathematical psychology proper. The essay can perhaps be considered as in a similar spirit, although differing in content, to previous editorial-like reviews of general or specific aspects of mathematical psychology such as Estes (1975), Falmagne (2005), Luce (1997) that have appeared in this journal.

    I started in 2002 as Editor-in-Chief of a well established journal—MST (Measurement Science and Technology). It was a time when modern means of communication offered new opportunities for the scientific community—for all scientists and engineers whether at universities, in industry or at other institutions—to access better quality information in a shorter time. This development helped us to be more efficient in our daily scientific work and to anticipate new trends faster than before. A flood of information was created by different search engines. A few online journals or journals published in emerging countries with a similar profile to MST appeared on the market. MST had to provide new answers in response to these developments. In 2002 I postulated two requirements to the journal. Firstly, the publisher has to be up to date. My impression over the years has been that IOPP is excellently organized. That has made it easier for the board members and all our reviewers to concentrate on the scientific aspects of our input to the journal. During all my visits to Bristol or my contacts with the IOPP staff I always met very professional and enthusiastic staff members. They have not only supported and encouraged the ideas and initiatives of the Editorial Board members, but they have also worked hard on establishing one of the most effective journal operations in the field of measurement science and technology. Many authors are well aware of this. Thus I am able to declare that the first requirement for a successful journal has been met. Secondly, the scientific level has to be high and the journal should attract readers from all over the world. This task was the responsibility of the Editorial Board members and of myself. Our strategy was on the one hand to ensure continuity in MST but on the other hand to be open to new trends and developments. Examples of these new aspects of the journal are fields like micro- and nanometrology, measurement techniques for

    Peer review is a widely accepted instrument for raising the quality of science. Peer review limits the enormous unstructured influx of information and the sheer amount of dubious data, which in its absence would plunge science into chaos. In particular, peer review offers the benefit of eliminating papers that suffer from poor craftsmanship or methodological shortcomings, especially in the experimental sciences. However, we believe that peer review is not always appropriate for the evaluation of controversial hypothetical science. We argue that the process of peer review can be prone to bias towards ideas that affirm the prior convictions of reviewers and against innovation and radical new ideas. Innovative hypotheses are thus highly vulnerable to being "filtered out" or made to accord with conventional wisdom by the peer review process. Consequently, having introduced peer review, the Elsevier journal Medical Hypotheses may be unable to continue its tradition as a radical journal allowing discussion of improbable or unconventional ideas. Hence we conclude by asking the publisher to consider re-introducing the system of editorial review to Medical Hypotheses.

    Computers are nearly ubiquitous in academic medicine, and authors create and compile much of their work in the electronic environment, yet the process of manuscript submission often fails to utilize the advantages of electronic communication. The purpose of this report is to review the submission policies of major academic journals in the field of radiology and assess current editorial practices relating to electronic submission of academic works. The authors surveyed 16 radiologic journals that are indexed in the Index Medicus and available in our medical center library. They compared the manuscript submission policies of these journals as outlined in recent issues of the journals and the corresponding worldwide web sites. The authors compared the journals on the following criteria: web site access to instructions; electronic submission of text, both with regard to initial submission and final submission of the approved document; text hardcopy requirements; word processing software restrictions; electronic submission of figures, figure hardcopy requirements; figure file format restrictions; and electronic submission media. Although the trend seems to be toward electronic submission, there currently is no clear-cut standard of practice. Because all of the journals that accept electronic documents also require a hardcopy, many of the advantages gained through electronic submission are nullified. In addition, many publishers only utilize electronic documents after a manuscript has been accepted, thus utilizing the benefits of digital information in the printing process but not in the actual submission and peer-review process.

    Antecedentes: el cambio climático tiene consecuencias en la salud, el medio ambiente y la sociedad. Las áreas verdes urbanas son importantes en la planeación de las ciudades para promover la interacción de los ciudadanos con el ambiente y la salud. La falta de planeación y diseño de estas áreas y la mala selección de árboles han contribuido a aumentar la incidencia de alergia al polen entre la población. Con frecuencia los programas de reforestación ambiental no toman en cuenta el potencial alergénico de algunas especies. El gobierno de Nuevo León en los últimos cuatro años ha plantado cerca de 18 mil árboles de la especie Quercus, además de un número indeterminado de árboles de la especie Fraxinus, cuyo polen es alergénico. Objetivo: identificar el cambio en la sensibilización al polen de árboles de acuerdo con los programas de reforestación ambiental. Material y método: estudio restrospectivo y descriptivo en el que se analizaron las pruebas cutáneas positivas para polen de árboles de los últimos cuatro años, correlacionando entre la especie de árbol utilizada para la reforestación y el aumento de la sensibilidad a ésta. Resultados: se encontró un incremento estadísticamente significativo en la sensibilización al polen de las especies con las que se reforestó Nuevo León, además de disminución en la sensibilización a las especies con las que no se reforesta. Conclusiones: la reforestación contribuye, en cierta medida, al cambio en el patrón de la positividad de las pruebas cutáneas y puede traer como consecuencia exacerbaciones más frecuentes de enfermedades respiratorias. Es una actividad que debe ser regulada y asesorada siempre por expertos.

    2014-01-01

    Background Trough collections of plants and interviews with 110 individuals, an ethnobotanical study was conducted in order to determine the knowledge and use plant species in Rayones, Nuevo Leon, Mexico. The aim of this study was to record all useful plants and their uses, to know whether differences exist in the knowledge about the number of species and uses between women and men, and to know if there is a correlation between the age of individuals and knowledge of species and their uses. Methods A total of 110 persons were interviewed (56 men, 56 women). Semistructured interviews were carried out. The data were analyzed by means of Student t test and the Pearson Correlation Coeficient. Results A total of 252 species, 228 genera and 91 families of vascular plants were recorded. Astraceae, Fabaceae and are the most important families with useful species and Agave and Opuntia are the genera with the highest number of useful species. One hundred and thirty six species are considered as medicinal. Agave, Acacia and Citrus are the genera with the highest number of medicinal species. Other uses includes edible, spiritual rituals, construction and ornamentals. There was a non-significant correlation between the person’s age and number of species, but a significant very low negative correlation between the person’s age and number of uses was found. Conclusions Knowing their medicinal uses is an important issue for the people of Rayones. Boiling and preparing infusions are the main ways of using plants by residents. The leaves, the branches, and the fruits are the most commonly used parts. Almost 18% of the flora is used for wood and construction purposes. Several uses such as cosmetic, shampoo, firming skin tonics and health hair products recorded in Rayones has not been reported for other areas in the state of Nuevo León. In Rayones, women have a greater knowledge about plants and their uses than men, particularly, medicinal plants, but, men have a greater

    Welcome to 2013; another great year for technology in our journal, Smart Materials and Structures (SMS). Last year, SMS grew by some 11% while maintaining a high Impact Factor above 2 and a rejection rate of 60%. The Editorial Board and I are pleased with this outcome, as it's indicative of the relevance and vibrancy of SMS to our research community. SMS continues to have a leading role within our community of researchers in the field of smart materials and smart systems technology. As always the quality of SMS is something that the Editorial Board takes very seriously. I have instructed the Editorial Board and our reviewers to scrutinize manuscripts, not only for originality and contributions to the field of smart materials and structures, but to consider the potential impact on the technology. In addition, we are doing more to architect the content of our issues, creating a conduit for exciting developments, developing review topics, and publishing focus issues that cover current technological trends. We would like to promote SMS as a medium to accelerate the promotion of the latest technology. Toward this end, SMS has instituted the Fast Track Communication (FTC). FTCs are short, urgent announcements reporting new and timely developments in the field. They benefit from extra post-publication promotion and accelerated peer review. SMS also has a strong program of topical review articles. Many of us are professors, involved with the training of new researchers to our field, and the value of review articles to education and training cannot be overstated. Such articles allow a reader to 'get up to speed' quickly in a new area, whether they be new graduate students or seasoned technologists deciphering what smart materials has to offer a particular application. Review topics are considered by me and the Editorial Board for content. If approved, SMS will commission a writer to prepare the article for which they will receive a fee in appreciation for the service they

    The purpose of this study was to identify the health needs of the non-institutionalized population, 65 years and over, residing in a sector of the community of Puerto Nuevo. This was the first urbanization established in Puerto Rico in the early 50's. The "snowball" technique was use to identify all the residents 65 year and over of the mentioned sector. Eighty five elderly persons were interviewed to gather data of the following variables: demographics, health conditions, preventive measures, activities of daily living (ADLs, IADLs), health services utilization, psychosocial aspects and use of programs and services available for the elderly population. Statistical analysis included descriptive measures and chi-square. Results revealed a population with a higher education and economic level than the average for this age group in Puerto Rico. People over 75 years over reported more functional limitations than the 65-74 years interviewees did. In comparison with men, women were less educated and presented a higher percent of widows, persons living alone and functional limitations. In almost all the interviewees, help was available in case of need. The majority expressed satisfaction with their family and social lives. Very few utilized programs and services available for elderly persons. It is concluded that in order to improve their quality of life, this population needs to be managed in an holistic mode to address their biopsychosocial needs and to be educated in health promotion issues to prevent further functional limitations. They also need education about the available services for elderly persons.

    An asphalt factory has operated intermittently near the urban area of Nuevo Vallarta on Banderas Bay, Nayarit, Mex. This factory has emissions that can affect the health of people living in the colonies nearest are Valle Dorado and San Vicente. The dispersion of emissions depends on the wind (sea breeze-land breeze) and the roof of the inversion, these phenomena determined by the density and temperature of the lower layers of the atmosphere. Asphalts are dark colored binder materials, formed by a complex non-volatile hydrocarbon chains and high molecular weight. Asphalts are produced from petroleum, but by a process of evaporation of the volatiles, leaving the asphalt alone. Therefore, the material emitted by the fireplace are mainly low molecular weight hydrocarbons known as polycyclic aromatic hydrocarbons (PAHs). The Emergency Response Guide 2008 developed by various agencies in Canada, U.S. and Mexico mentions that the hydrocarbon gas can have health effects. Animal studies have shown that PAHs can cause harmful effects to the skin, body fluids and some PAHs are carcinogenic.

    A poorly chosen article title may make a paper difficult to discover or discourage readership when discovered, reducing an article's impact. Yet, it is unclear how the structure of a manuscript's title influences readership and impact. We used manuscript tracking data for all manuscripts submitted to the journal Functional Ecology from 2004 to 2013 and citation data for papers published in this journal from 1987 to 2011 to examine how title features changed and whether a manuscript's title structure was predictive of success during the manuscript review process and/or impact (citation) after publication. Titles of manuscripts submitted to Functional Ecology became marginally longer (after controlling for other variables), broader in focus (less frequent inclusion of genus and species names), and included more humor and subtitles over the period of the study. Papers with subtitles were less likely to be rejected by editors both pre- and post-peer review, although both effects were small and the presence of subtitles in published papers was not predictive of citations. Papers with specific names of study organisms in their titles fared poorly during editorial (but not peer) review and, if published, were less well cited than papers whose titles did not include specific names. Papers with intermediate length titles were more successful during editorial review, although the effect was small and title word count was not predictive of citations. No features of titles were predictive of reviewer willingness to review papers or the length of time a paper was in peer review. We conclude that titles have changed in structure over time, but features of title structure have only small or no relationship with success during editorial review and post-publication impact. The title feature that was most predictive of manuscript success: papers whose titles emphasize broader conceptual or comparative issues fare better both pre- and post-publication than do papers with organism

    This editorial explains the reasoning behind The Journal of Experimental Psychology: Animal Behavior Processes name change. This Journal started publication in 1975 as a result of a major reorganization of the American Psychological Association's basic science journals. To signal that expansion of interest, the name of the journal has been changed to Journal of Experimental Psychology: Animal Learning and Cognition. This change is not meant to discourage submission of the types of manuscripts that have most frequently appeared in the journal in recent years but to encourage submission of papers across a broader range of topics.

    Groundwater is an important component of the freshwater system and its role is becoming even more prominent as the more accessible surface water resources become increasingly exploited to support increasing populations and development. Yet despite its significance, there has been comparatively little research conducted on groundwater relative to surface water resources, particularly in the context of climate change impact assessment. This focus issue has therefore been assembled to expand upon the currently limited knowledge of groundwater systems and their links with climate. Many of the papers included here explore the interrelated issues of groundwater resources, climate-related changes and vulnerabilities at a regional scale in different continents and globally.

    Since 1991, Measurement Science and Technology has awarded a Best Paper prize. The Editorial Board of this journal believes that such a prize is an opportunity to thank authors for submitting their work, and serves as an integral part of the on-going quality review of the journal. The current breadth of topical areas that are covered by MST has made it advisable to expand the recognition of excellent publications. Hence, since 2005 the Editorial Board have presented 'Outstanding Paper Awards' in four subject categories: Fluid Mechanics; Measurement Science; Precision Measurements; and Sensors and Sensing Systems. 2006 Award Winners—Fluid Mechanics The article 'Molecular tagging velocimetry and thermometry and its application to the wake of a heated circular cylinder' by Hui Hu and Manoochehr Koochesfahani, published in volume 17, issue 6, pp 1269-1281, was selected by the cognizant Editorial Board Members as the Outstanding Paper in Fluid Mechanics for 2006. This consensus selection was accompanied by the collective judgment that a number of other very strong contributions were published in 2006. These other papers have been added to the 2006 Highlights in the electronic version of the journal. The paper by Hu and Koochesfahani is recognized for its contribution to the use of molecular tagging techniques in the service of velocity and temperature measurements. The paper clearly articulates the prior state-of-the-art in this area and it communicates the required equipment and procedures to utilize this experimental tool. The capabilities of their technique are made apparent by the simultaneous (u,v,T) observations in the wake of a circular cylinder. The normalized heat flux vectors, (\\overline{u_j'T'})/U\\Delta T, demonstrate one of the beneficial results of obtaining a whole-field view of the velocity and temperature distributions. The authors also have carefully noted the intrinsic limitations of their technique. 2006 Award Winners—Measurement Science The

    In this study, we assessed in gills of native ribbed mussels Aulacomya atra atra from three sites within Nuevo Gulf (Northern Patagonia) several biomarkers such as reactive oxygen species (ROS), lipid radicals (LR), malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST) and metallothionein (MT). Furthermore, concentrations of main trace metals (Fe, Al, Zn, Cu, Cd and Pb) were quantified in mussel tissue. Results showed significant induction of SOD, GST, MT and MDA, as well as, higher concentration of Fe, Al and Cd in winter than in summer. The high MDA content measured in mussels from Folías Wreck seemed to be caused by the very high levels of Fe that would come from the corrosion of the vessel. Mussels from the control site Punta Cuevas presented the lowest levels of Cd and the highest of Al in winter. Despite positive correlations were found between Al and GST and MT, no spatial differentiation was detected in those biomarkers. On the other hand, MT was only related to Al been most likely influenced by environmental variables than by the trace metals. It has to be highlighted that the relationship detected among water temperature, nutrients and antioxidant responses in gills is probably related to the fact that this tissue is in direct contact with water and it is sensitive to its fluctuations. Taking into account that mussel gill is a tissue actively proliferating and the first target of contaminants present in water, so that changes in its antioxidant system can provide an earlier warning signal than in other tissues.

    tribocorrosion processes. The formation of a coating layer on magnesium alloys from phosphonate imidazolium ionic liquids by immersion and by chronoamperometry has been described. The new coatings reduce the abrasive wear in the magnesium-aluminium alloy but they are not effective in the magnesium-zinc alloy, which prevent the formation of continuous coatings. Los liquidos ionicos son sales liquidas a temperatura ambiente o bajas temperaturas que presentan excelentes propiedades fisico-quimicas. En el presente trabajo se estudian como lubricantes en problemas tribologicos complejos como la lubricacion de metales contra si mismos, el desarrollo de lubricantes base agua y de nuevas superficies autolubricadas. Cuando no es posible reducir la friccion y desgaste mediante lubricacion, como en las aleaciones de magnesio, los liquidos ionicos se han estudiado como precursores de recubrimientos protectores. Se han determinado las interacciones superficiales y los procesos de corrosion sobre cobre y sobre acero con diferentes liquidos ionicos proticos y aproticos para desarrollar nuevos lubricantes y aditivos. En el contacto cobre/cobre, excepto el liquido ionico protico derivado del oleato, todos los liquidos ionicos estudiados presentan mejor comportamiento tribologico que el lubricante comercial Polialfaolefina 6. En el contacto acero/zafiro, los nuevos liquidos ionicos proticos son buenos lubricantes cuando se utilizan en estado puro, y, como aditivos en agua, generan peliculas adsorbidas sobre la superficie del metal reduciendo la friccion y el desgaste tras la evaporacion del agua. Para evitar el periodo de alta friccion inicial en presencia de agua, se han generado peliculas superficiales de liquido ionico sobre el acero en condiciones estaticas. El mejor comportamiento lubricante tanto en el contacto cobre/cobre como en el contacto acero/zafiro se obtiene para el liquido ionico protico derivado del anion adipato, con dos grupos carboxilicos.

    The goal of the International Journal of Behavioral Nutrition and Physical Activity (IJBNPA) is to be the leading diet and physical activity journal. To achieve this aim we embrace and publish a number of different research designs from small, but in depth, qualitative studies to large scale cohort studies. IJBNPA prioritises research based on randomised controlled trials (RCTs), systematic reviews (with or without meta-analyses, as appropriate), and well conducted observational studies that expand knowledge and understanding of the area. IJBNPA will also consider and publish other study designs that are of sufficient quality such as strong or ground-breaking methodological papers, rigorous qualitative studies, debate papers and commentaries. However, due to the demands on the journal, we publish pilot studies only in exceptional circumstances and we do not publish protocol papers or letters to the editors. The goal of this editorial is to highlight to our readers and authors the process by which we identify which papers to review and publish along with our editorial priorities.

    Exposure to idealized body images has been shown to lower women's body satisfaction. Yet some studies found the opposite, possibly because real-life media (as opposed to image-only stimuli) often embed such imagery in messages that suggest thinness is attainable. Drawing on social cognitive theory, the current content analysis investigated editorial body-shaping and weight-loss messages in popular women's health and fitness magazines. About five thousand magazine pages published in top-selling U.S. women's health and fitness magazines in 2010 were examined. The findings suggest that body shaping and weight loss are a major topic in these magazines, contributing to roughly one-fifth of all editorial content. Assessing standards of motivation and conduct, as well as behaviors promoted by the messages, the findings reflect overemphasis on appearance over health and on exercise-related behaviors over caloric reduction behaviors and the combination of both behaviors. These accentuations are at odds with public health recommendations.

The essence of the following citation was provided by Board Member Dr Mark Wernet: The paper of Chen and Katz describes a technique for eliminating the 'peak locking' bias error endemic to estimating the PIV correlation peak location. Particle image velocimetry (PIV) is used widely in both fundamental and applied fluid mechanics. In essence, a two-dimensional velocity map is extracted from two successive high-resolution images of light scattered by minute tracer particles. The incident light is derived from two laser beams which have been expanded into sheets. A precise time delay is imposed between the two laser light sheets. The cross-correlation of the scattered light intensity within corresponding small interrogation regions in the two images gives the displacement of the particles and hence the local velocity. Typically, in PIV processing, the correlation peak location is determined by fitting a curve through the correlation peak. This process is known to suffer from a bias error where the estimated

    A brief overview of the ongoing climatic and environmental changes in Northern Eurasia serves as an editorial introduction to this, the second, special Northern Eurasia Earth Science Partnership Initiative (NEESPI) focus issue of Environmental Research Letters. Climatic changes in Northern Eurasia over the last hundred years are reflected in numerous atmospheric and terrestrial variables. Many of these are noticeably significant above the confidence level for 'weather' or other (fire regime, ecosystem change) noise and thus should be further investigated in order to adapt to their impacts. In this focus issue, we introduce assorted studies of different aspects of contemporary change in Northern Eurasia. Most of these have been presented at one of the NEESPI workshops (for more information see neespi.org) and/or American Geophysical Union and European Geosciences Union NEESPI open sessions during the past year. These studies are diverse, representing the diversity of climates and ecosystems across Northern Eurasia. Some of these are focused on smaller spatial scales and/or address only specific aspects of the global change implications across the subcontinent. But the feeling (and observational evidence) that these changes have already been quite rapid and can have global implications inspires us to bring this suite of papers to the readers' attention.

    Stoneham, A. M.

    2003-12-01

    Today, the median time from receipt to publication for regular articles in Journal of Physics: Condensed Matter is about four months. Letters can be reviewed, possibly revised, and on the Web in little more than a week in favourable circumstances, and the median time is six weeks. When the Journal of Physics series was started, over thirty years ago, Letters took typically three months from receipt to print, and articles took substantially longer. Now that publication times for regular papers are of a similar order to those of Letters in the past, it makes sense to review the types of submission we accept as Letters and put a higher premium on urgency. In the past, Letters have been of several different types. There have been Letters giving a first announcement of some important new result, and these have a justifiable urgency and need for priority. In addition, there have been what one might call short papers, self-contained pieces of work, but with no requirement for rapid publication. The Editorial Board of Journal of Physics: Condensed Matter has decided that in future all Letters published will have to satisfy criteria of significant importance and urgency. To achieve this, all manuscripts submitted as Letters will be processed as follows. First, the Letter will be looked at by a Board Member, who will decide whether or not the proposed Letter has the right level of importance, urgency, and interest to appear as a Letter. The Board Member will not usually act as referee, unless the Letter is in a field in which they normally referee. If their decision is yes, then the manuscript will go to a regular referee. Special efforts will be made to ensure rapid treatment, both by the referee and in processing at Bristol. The ideal Letter would address a significant topic in condensed matter physics. It would be recognized as important by a large number of condensed matter physicists, including those whose research area is a different one. So it is crucial that the

    2009 is Inverse Problems' 25th year of publication. In this quarter-century, the journal has established itself as the premier publication venue for inverse problems research. It has matured from its beginnings as a niche journal serving the emerging field of inverse and ill-posed problems to a monthly publication in 2009 covering all aspects of a well-established, vibrant and still-expanding subject. Along with its core readership of pure and applied mathematicians and physicists, Inverse Problems has become widely known across a broad range of researchers in areas such as geophysics, optics, radar, acoustics, communication theory, signal processing and medical imaging, amongst others. The journal's appeal to the inverse problems community and those researchers from the varied fields that encounter such problems can be attributed to our commitment to publishing only the very best papers, and to offering unique services to the community. Besides our regular research papers, which average a remarkably short five months from submission to electronic publication, we regularly publish heavily cited topical review papers and topic-specific special sections, which first appeared in 2004. These highly-downloaded invited articles focus on the latest developments and hot topics in all areas of inverse problems. No other journal in the field offers these features. I am very pleased to take Inverse Problems into its 25th year as Editor-in-Chief. The journal has an impressive tradition of scholarship, established at its inception by the founder and first Editor-in-Chief, Professor Pierre Sabatier. Professor Sabatier envisioned the journal in 1985 as providing a medium for publication of exemplary research in our intrinsically interdisciplinary field. I am glad to say that the support of our authors, readers, referees, Editors-in-Chief, Editorial Boards and Advisory Panels over the years, has resulted in Inverse Problems becoming the top publication in this field, publishing

    2004-01-01

    Early detection of breast cancer by mammographic screening has the potential to dramatically reduce mortality rates, but many women do not comply with screening recommendations. The media are an important source of health information for many women--through both direct social marketing advertisements and indirect dissemination of information via editorial content. This study investigated the accuracy of breast cancer detection messages in the top-selling Australian women's magazines and three weekend newspapers in the six-month period from December 2000 to May 2001 that included any reference to breast cancer and found that current coverage of breast cancer in the Australian print media conveys messages that are unlikely to encourage appropriate screening.

    structures and catalyst systems that enhance diffusion. These and other issues concerning both molecularly and chemically bound hydrogen storage materials have begun to be addressed through an understanding of their behavior and their manipulation on the nanoscale. This special issue of Nanotechnology provides a current survey of this endeavor. The themes covered in this issue include the thermodynamics and kinetics of hydrogen storage materials at the nanoscale; the structure of nanoporous adsorbents; the structure of hydrogen adsorbed in nanosized pores, and the behavior of nanoparticulate, nanocrystalline and nanoconfined metal and complex hydrides, including the form and effects of catalysts. These themes are addressed through theoretical, computational and experimental approaches. Although an ideal hydrogen storage material has not yet been identified, the papers in this issue indicate that the ideal material will likely be highly structured on the nanometer scale. To optimize the capacity and interaction energy of adsorbents, the pore size, shape and volume will need to be carefully controlled. Similarly, the diffusion lengths in hydride materials will need to be matched to crystallite and particle size. Furthermore, the diffusion lengths themselves will need to be tailored through the use of dopants, placement of catalysts and control of interface energies. We are grateful to the contributors for the high quality of their submissions. We also thank the editorial and production staff for their efficient and professional work and their guidance in the production of this issue.

A paper of the highest quality (Q1) was about ten times more likely to be found in the most-cited quintile than in the least-cited. While it is reassuring to find that the best papers in PMB are, indeed, cited more often on average, we cannot discount the hypothesis that both measures might be influenced by an extrinsic factor, such as the reputation of the authors. We suggest that a study similar to ours be performed for a journal that utilizes a system of double-blind peer review.

    It is a pleasure and an honour for me to be taking over as Editor-in-Chief of Measurement Science and Technology. MST is well known across research communities worldwide as a leading journal in which to publish new techniques and instrumentation. It has gained this enviable position largely because of the excellent guidance of its Editorial Board and dedicated staff at Institute of Physics Publishing over many years. I want to highlight in particular the contribution of the outgoing Editor Peter Hauptmann, and other Editors before him, in making the journal truly international. We thank Peter immensely for all his hard work in leading the journal, having exceptionally served two terms, each of five years. I come into the post of Editor at a very interesting and challenging time for research. The global recession is leading to cuts in research funding in many countries, researchers and their outputs are coming under closer scrutiny than ever before, and more is being expected of them. Journals play a critical role in monitoring and maintaining research standards, but we should be careful not to assume that journal Impact Factor is the sole measure of research quality. Although expediency may sometimes demand it, Impact Factor, as practitioners know, is subject dependent. One of the great things about science and technology for me is its level playing field. The key point is still innovation no matter where the work is done or where it is published. MST has a long pedigree of being the natural home of the highest quality papers from leading researchers wishing to report novel instrumentation and techniques. 2013 will mark the 90th anniversary of MST and we look forward to celebrating in style its sustained success. I recall with pride the first paper I published in Journal of Physics E: Scientific Instruments (as MST was previously titled) back in 1977. The paper reported the design and application of an early fluorescence lifetime spectrometer that I had constructed

The workshop 'Pulsed electrical discharges in water: fundamentals and applications', organized by Professor Pavel Sunka, reviewed the scientific challenges related to fundamentals of pulsed discharges initiated in slightly conductive liquid water solutions. The workshop 'Physics and applications of pulsed high-current capillary discharges', organized by Dr Karel Kolácek, addressed scientific challenges and technological applications of high-current capillary discharges pinching into a nearly uni-dimensional dense plasma column composed of a quasi-neutral mixture of very hot electrons and multiply charged ions. All ICPIG speakers were invited to prepare peer-reviewed articles based on their conference lectures for the journal Plasma Sources Sciences and Technology (PSST) in the form of either reviews or original works. A selection of invited papers is published in this special issue. We would like to thank all authors for their effort in preparing interesting articles for the readers of PSST. We would like to thank once more all members of the International Scientific Committee chaired by Professor Jerzy Mizeraczyk as well as the members of the Local Organizing Committee and the National Advisory Board for their considerable contributions to the success of the conference. We are particularly grateful to the Editorial Board of Plasma Sources Science and Technology for the opportunity to bring the 28th ICPIG to a wider audience.

    The latest impressive advancements in the epitaxial fabrication of semiconductors and in the refinement of characterization techniques have the potential to allow insight into the deep relation between materials' structural properties and their physical and chemical functionalities. Furthermore, while the comprehensive (nano)characterization of semiconductor materials and structures is becoming more and more necessary, a compendium of the currently available techniques is lacking. We are positive that an overview of the hurdles related to the specific methods, often leading to deceptive interpretations, will be most informative for the broad community working on semiconductors, and will help in shining some light onto a plethora of controversial reports found in the literature. From this perspective, with this special issue we address and highlight the challenges and misinterpretations related to complementary local (nanoscale) and more global experimental methods for the characterization of semiconductors. The six topical reviews and the three invited papers by leading experts in the specific fields collected in here are intended to provide the required broad overview on the possibilities of actual (nano)characterization methods, from the microscopy of single quantum structures, over the synchrotron-based absorption and diffraction of nano-objects, to the contentious detection of tiny magnetic signals by quantum interference and resonance techniques. We are grateful to all the authors for their valuable contributions. Moreover, I would like to thank the Editorial Board of the journal for supporting the realization of this special issue and for inviting me to serve as Guest Editor. We greatly appreciate the work of the reviewers, of the editorial staff of Semiconductor Science and Technology and of IOP Publishing. In particular, the efforts of Alice Malhador in coordinating this special issue are acknowledged.

    Objective To examine the effect on BRCA testing and mastectomy rates of a widely viewed 2013 New York Times editorial by public figure Angelina Jolie that endorsed BRCA testing and announced Jolie’s decision to undergo preventive mastectomy. Design Observational study with difference-in-difference analysis. Setting Commercially insured US population. Participants Women aged 18-64 years with claims in the Truven MarketScan commercial claims database (n=9 532 836). Main outcome measures Changes in BRCA testing rates in the 15 business days before versus after 14 May 2013 (editorial date) compared with the change in the same period in 2012; mastectomy rates in the months before and after publication, both overall and within 60 days of BRCA testing among women who were tested; national estimates of incremental tests and expenditures associated with Jolie’s article in the 15 days after publication. Results Daily BRCA test rates increased immediately after the 2013 editorial, from 0.71 tests/100 000 women in the 15 business days before to 1.13 tests/100 000 women in the 15 business days after publication. In comparison, daily test rates were similar in the same period in 2012 (0.58/100 000 women in the 15 business days before 14 May versus 0.55/100 000 women in the 15 business days after), implying a difference-in-difference absolute daily increase of 0.45 tests/100 000 women or a 64% relative increase (P<0.001). The editorial was associated with an estimated increase of 4500 BRCA tests and $13.5m (£10.8m; €12.8) expenditure nationally among commercially insured adult women in those 15 days. Increased BRCA testing rates were sustained throughout 2013. Overall mastectomy rates remained unchanged in the months after publication, but 60 day mastectomy rates among women who had a BRCA test fell from 10% in the months before publication to 7% in the months after publication, suggesting that women who underwent tests as a result of to the editorial

    The decision-making process includes a series of activities undertaken in biomedical journals from the moment a manuscript is received until it is accepted or rejected. Firstly, the manuscript is evaluated by the members of the Editorial Board, who analyze both its suitability for the journal and its scientific quality. After this initial evaluation, the article is evaluated by peer reviewers, an essential process to guarantee its scientific validity. Both the Editorial Board and the peer reviewers usually use checklists which are of enormous help in this task. Once the biomedical article has been accepted, the publication process is started, which in turn includes a series of steps, beginning with technical and medical review of the article's contents and ending with the article's publication in the journal. The present article provides a detailed description of the main technical and ethical issues involved in the processes of decision-making and publication of biomedical articles.

  19. Medicinal plants in the southern region of the State of Nuevo León, México

    2012-01-01

    Background Although the flora of the State of Nuevo León is well known, there are few records of ethnobotancial information. An ethnobotanical study was undertaken in order to know the medicinal plants used by people living at the scrublands and oak-pine forest areas in the southern Nuevo León. Collection of plants specimens and interviews were carried out among the people of the municipalities of Aramberri, Galeana, and Zaragoza. Since former studies in the region are scarce, the aim of this work was to record the medicinal species and their uses in the scrublands and oak-pine forest areas, of southern Nuevo León, Mexico, and also to know if there are differences in the number of species and number of uses knowledge by people. Methods Field work was carried out over a 2 years period; useful plants were collected and a total of 105 people from 46 different villages were interviewed. A database was compiled using data collected by means of semi structured interviews. The data were analyzed by means of non-parametric statistics, using goodness-of-fit test (Chi-squared) (number of species known by people of each municipality, number of uses known by people of each municipality), Chi-squared modified to incorporate the Yates Correction (number of species known by people living at scrublands and oak-pine forest); the Kruskall-Wallis test (number of species known by women and men of the three municipalities), and the Spearman’s rank correlation coefficient (age and number of species known, and age and number of uses). Results A total of 163 medicinal plant species were recorded in the study area, comprising 108 wild and 55 cultivated plants. A total of 117 species were recorded in the oak-pine forest, and 111 in the scrublands area, a total of 68 were recorded in both areas; 68 medicinal species are used in all three municipalities, 40 wild and 28 cultivated. We documented 235 different medicinal uses. The most common plant parts used for medicinal purposes were

    The purpose of this study was to assess the levels of polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane (DDT), dichlorodiphenyldichloroethane (DDE), and four heavy metals (arsenic, cadmium, and lead) in outdoor surface soils (50 samples) collected from the metropolitan area of Monterrey in Mexico. Total PBDEs levels ranged from 1.80 to 127 µg/kg, with mean total PBDEs level of 14.2 ± 21.5 µg/kg (geometric mean ± standard deviation). For PCBs, the mean total level in the studied soils was 23.5 ± 20.2 µg/kg (range 4.0-65.5 µg/kg). An important finding in our study was that all soil samples (100%) had detectable levels of the metabolite p,p'-DDE. Moreover, the mean total DDT level (∑p'p-DDT and p'p-DDE) was approximately 132 ± 175 µg/kg. The mean levels for arsenic, cadmium, and lead in soil were 5.30 ± 1.35 (range 1.55-7.85) mg/kg, 2.20 ± 1.20 (range 0.65-6.40) mg/kg, and 455 ± 204 (range 224-1230) mg/kg, respectively. Our study has several limitations, the most notable of which is the small sample of soils evaluated. However, this screening study provided concentration data for the occurrence of POPs and four heavy metals in soil from the metropolitan area of Monterrey, Nuevo Leon, Mexico, and taking into consideration that soil is an important pathway of exposure for people, a biomonitoring program for the surveillance of the general population in the metropolitan area of Monterrey, Nuevo Leon is deemed necessary.

    Applied Physics is now turning into its fourth year of existence. It has survived in spite of a hard childhood. Michel Sauzade, our co-editor in chief, passed away suddenly at the end of the first year. As he had been very positive into our common task of launching this new Journal, resulting from the merging of Journal de Physique III with Microscopy, Microanalysis, Microstructures , the situation became quite critical. Furthermore this sad event was superposed to all the problems which a new title has to face within the present context of strong competition between journals and with the electronic press. We could continue, mostly thanks to the efforts of all members of the Editorial Board, and in particular of the most ancient ones, whom I want to warmly thank for their permanent support all along these past years. It seems now reasonable to strike a first balance after three years of publication. All indicators, relative to the numbers of manuscript submissions, to the rate of acceptance, to the widening of the geographic origin, to the distribution between the major topics, suggest that we are heading into the right direction. However, the changes have not yet been sufficiently established. We definitely need more manuscripts of high quality from all around the world, and in particular from European countries, in order to improve the fit of the content of the journal with its title. The situation is now ready for building a more stable organisation of the Editorial Board. Two Editors-in-Chief have therefore been appointed, one of them covering the Materials Science topics and the second one being in charge of the other subjects with a strong emphasis on the Optics, Photonics and Electronics sections. The Editorial Committee is being renewed by half, in order to adapt more consistently the extent of the competence which they represent to a field of research and development in rapid evolution. This will also show through the changes introduced into the definition

    After five years of significant growth and development, and with the Impact Factor (IF) now firmly placed over 2.0, Journal of Physics D: Applied Physics (JPhysD) has seen a double change at the helm in the last 12 months. Giorgio Margaritondo from École Polytechnique Fédérale de Lausanne, Switzerland took over as Editor-in-Chief from Pallab Bhattacharya, while Olivia Roche took over as Publisher from Sarah Quin. We inherited a strong, successful journal. With its IF of 2.105, excellent publication times and flexible, responsive management, JPhysD has established itself as the place to publish high-quality research papers in applied physics. Having introduced Fast Track Communications (FTCs) in 2008, we also became an outlet for short, high-impact letter-like articles. FTCs, with their particularly strict refereeing, add an extra mark of quality to the content. We are keen to continue developing and strengthening the journal to make it the first choice for authors and readers. We are lucky to be working in the exciting, rapidly-changing field of applied physics. The pace of development can sometimes be breathtaking. One of our first actions on taking over the journal was to look again at its scope. We felt it was time to respond to all the recent developments, to ensure that our scope encompasses the latest, cutting-edge research topics—so that it matches the reality of applied physics today. The first issue of the journal that will see this new scope implemented will be issue 41 of this volume. We would like to thank the entire Editorial Board for their hard work during this scope review. The greatest change during this review has been the merging of two sections, 'Functional surfaces and interfaces' and 'Structure and properties of matter', into a new section entitled 'Condensed matter, interfaces and related nanostructures'. This change reflects the significant developments in these connected fields in recent years, particularly the natural evolution of

In the ten years I have held this position, I have seen many new topics entering the journal: spintronics, organic semiconductors, and Dirac fermion physics, to name just a few. The journal has also witnessed a strong internationalization of the authorship, with an especially strong increase in contributions from the Far East—a growth that is likely to continue in the coming years. I am certain that Kornelius will do an excellent job in guiding the journal through the developments of the coming decade. I would like to thank the publishing team of SST, or rather the three consecutive teams I witnessed during my tenure at the journal, for the help and support they have given me. The people at IOP Publishing are doing a great job in running the journal, and have made it possible to considerably reduce the time to publication for our submissions. I much enjoyed the collaboration with the other members of the Editorial Board; our annual meetings have always been a source of inspiration. Last, but certainly not least, I would like to thank you, the scientific community, authors, referees and readers, for your continuing support of the journal.

    On January 1, 2014, editorial leadership of Medical Physics passed from esteemed long-time Editor Bill Hendee to a collective editorial group composed of the three presenters listed above. In this presentation, we would like to outline our vision for the future of Medical Physics and review recent work-in-progress initiatives to implement this vision. Finally, we will close with guidance to authors on how to write a good Medical Physics paper. Vision for Medical Physics and current initiatives: Jeff Williamson, Editor-in-Chief We cannot improve on Dr. Hendee's succinct vision statement “to continue the Journal's tradition of publishing the very best science that propels our discipline forward and improves our contribution to patient care.” More concretely, the Journal should be s the preeminent forum for electronic exchange of cutting edge medical physics science. We seek to identify the best contributions in (a) high impact clinical physics innovations; (b) clinical translation and validation of basic science innovations; or (c) cutting edge basic science developments with potential for patient care improvements. Among the challenges and opportunities we face are: are electronic-only and open access publishing; trends towards more interactive, social-media based scientific communities; and diversification of the medical physics research, authorship, and readership domains, including clinical applications quite foreign to core ABR clinical competencies. To address these issues over the next 3 years, we have reduced the size of our Editorial Board and focused its efforts on improving the Journal's impact through 4 working groups (WGs): WG-1: Review process quality and selectivity Creation of 120 member Board of Associate Editors to improve review uniformity by placing Ms. management in fewer hands New reviewer guidelines and templates Answer: “what is the scope of medical physics research?” Recursive taxonomy for tagging review expertise and article contents

    technological solution in the early to late 1990s of confining atmospheric plasmas in a small volume of plasma generation (i.e. with a small volume-to-surface ratio) and then extending it towards a downstream sample [7]-[9]. These are among the first low-temperature atmospheric plasmas aimed particularly at the exploitation of their ability to invoke the active and rich reactive chemistry close to ambient temperature. The main applications of these early devices are precision surface modification of low-temperature dielectric materials, for example thin film deposition and etching [7]-[9]. Variations of the early plasma jets include atmospheric plasma sheet jets [10] for the treatment of largely planar objects (e.g. polymeric sheets) as well as large arrays of many plasma jets for the treatment of complex-structured objects (e.g. surgical tools and open human wounds) [11]. As a material processing technology, the sub-100oC atmospheric-pressure plasma jet has benefited over the years from many innovations. Whilst a detailed account and analysis of these is clearly outside the scope of this Editorial, it is worth stating that there are different avenues with which to maintain a moderate electron density at the plasma core so as to keep the gas temperature at the sample point below a ceiling level. Most of the early studies employed excitation at radio frequencies above 10 MHz, at which electrons are largely confined in the plasma generation region, and this limits the current flow to and gas heating in the plume region of the plasma jet. Other techniques of current limitation have since been shown to be effective, including the use of dielectric barriers across a very large frequency range of 1 kHz--50 MHz, sub-microsecond pulses sustained at kHz frequencies, pulse-modulated radio frequencies and dual-frequency excitation [12]-[15]. These and other techniques have considerably advanced the atmospheric-pressure plasma jet technology. The period of some 15 years since the above

    Northern elephant seals (Mirounga angustirostris Gill, 1866), inhabiting rookeries on the mainland of Año Nuevo State Reserve in central California, were investigated in 2012 for presence of hookworms (Uncinaria spp.). Material collected and examined for hookworms included: blubber (n = 15), stomach and intestines (n = 21) from dead pups; feces from the rectum of weaned pups (n = 23); sand containing apparent feces in areas of weaned pups (n = 28) and sand without apparent feces in areas of weaned pups (n = 54); milk from females (n =23) at 5 days and about 23 to 26 days postpartum; and placenta from one female. Evidence of hookworm presence was not detected in any of the samples examined. Possible reasons why hookworms were not found in northern elephant seals on the mainland of Año Nuevo State Reserve are discussed.

    The Ni, Fe and Co contents of metal phases in the Allende, Holbrook and Nuevo Mercurio chondrites have been obtained using an automated electron microprobe fitted with both wavelength and energy dispersive spectrometers. Co contents of kamacite in these chondrites are inconsistent with those reported previously, but the general tendency of Co to increase in the kamacite in chondrites from H, L to LL groups, is supported by the study. Although the variation patterns of Ni-Co observed so far for L4, H5 and CV3 chondrites are simple, six L6 chondrites, including those reported previously, show significant difference in Co contents and the concentration and abundance charcateristics of Ni-Fe-Co patterns of the metal phases. The great similarity of composition of each region of these patterns obtained from two samples of Holbrook and two samples of Allende which came from different collections, indicate that the variation patterns of Ni-Co in the metal phases provide a means of characterizing or 'fingerprinting', as do the great differences in the variation patterns of Fe-Ni-Co which occur from one chondrite to another or even within the same group and petrologic type.

    The concentration of pollen grains in the atmosphere over the metropolitan area of Monterrey, Nuevo Leon, Mexico, was analyzed throughout a year from March 2003-February 2004, focused on the genus Carya, Celtis, Cupressus, Fraxinus and Pinus owing to their interest as etiological pollinosis agents in diverse regions of the world. A 7-day Hirst type volumetric spore and pollen trap was located on a building roof of the city at 15 m from ground level for continuous sampling. The total quantity of pollen recorded for the study period was 21,083 grains/m(3), corresponding to 49.75 % of the taxa of interest. February and March were the months with higher pollen amounts in the air with 7,525 and 2,781 grains/m(3), respectively, and amounted to 49 % of total year through pollen. Fraxinus was the genus which contributed to the largest amount of pollen with 28 % of total grains (5,935 grains/m(3)) followed by Cupressus with 13 % (2,742 grains/ m(3)). Celtis, Pinus and Carya contributed with 5.3 % , 2.7 % , and 0.6 % of total pollen, respectively. These results indicate that Fraxinus and Cupressus are present in the area in sufficient quantity to indicate likely involvement in the origin of allergic disorders in the human population.

    Nearly one-third of the world’s population is infected with latent tuberculosis (LTBI). Tuberculosis (TB) rates in the border states are higher than national rates in both the US and Mexico, with the border accounting for 30% of total registered TB cases in both countries. However, LTBI rates in the general population in Mexican border states are unknown. In this region, LTBI is diagnosed using the tuberculin skin test (TST). New methods of detection more specific than TST have been developed, although there is currently no gold standard for LTBI detection. Our objective is to demonstrate utility of the Quantiferon TB gold In-Tube (QFT-GIT) test compared with the TST to detect LTBI among border populations. This is an observational, cross-sectional study carried out in border areas of the states of Nuevo Leon and Tamaulipas, Mexico. Participants (n = 210) provided a TST and blood sample for the QFT-GIT. Kappa coefficients assessed the agreement between TST and QFT-GIT. Participant characteristics were compared using Fisher exact tests. Thirty-eight percent of participants were diagnosed with LTBI by QFT-GIT. The proportion of LTBI detected using QFT-GIT was almost double [38% (79/210)] that found by TST [19% (39/210)] (P < 0.001). Concordance between TST and QFT-GIT was low (kappa = 0.37). We recommend further studies utilizing the QFT-GIT test to detect LTBI among border populations. PMID:26484340

    Optimum natural resource management and biodiversity conservation are desirable goals. These, however, often exclude each other, since maximum economic benefits have promoted drastic reductions in biodiversity throughout the world. This dilemma confronts local stakeholders, who usually go for maximizing economic inputs, whereas other social (e.g., academic) sectors are favor conservation practices. In this paper we describe the way two scientific approaches--landscape and participatory research--were used to develop sound and durable land use scenarios. These two approaches included expert knowledge of both social and environmental conditions in indigenous communities. Our major emphasis was given to detect spatially explicit land use scenarios and capacity building in order to construct a decision support system operated by stakeholders of the Comunidad Indigena de Nuevo San Juan Parangaricutiro in Mexico. The system for decision-making was fed with data from inventories of both abiotic and biotic biodiversity components. All research, implementation, and monitoring activities were conducted in close collaboration with members of the indigenous community. As a major result we obtained a number of forest alternative uses that favor emerging markets and make this indigenous community less dependent on a single market. Furthermore, skilled members of the community are now running the automated system for decision-making. In conclusion, our results were better expressed as products with direct benefits in local livelihoods rather than pure academic outputs.

    absorbed solar and net thermal radiative exchanges at the Earth's surface. Globally averaged, this surface radiation balance is positive, since radiative absorption, scattering and emission in the climate system act to generate an energy surplus at the surface and an energy deficit in the atmosphere (Liepert 2010). Evaporation, or more precisely its energy equivalent, the latent heat flux, is the main process that compensates for this imbalance between surface and atmosphere, since the latent heat dominates the convective energy flux over sensible heating. The radiative energy surplus at the surface is thus mainly consumed by evaporation and moist convection and subsequently released in the atmosphere through condensation. This implies that any alterations in the available radiative energy will induce changes in the water fluxes. Our focus in this editorial is therefore on the surface radiation balance as the principal driver of the global hydrological cycle. Note that this energetic view is in agreement with that of Richter and Xie (2008) who argue that the spatial and temporal behaviour of the process of evaporation is controlled by surface and atmospheric properties such as atmospheric stability, wind speed, moisture deficit and moisture availability. From radiation theory it is expected that with increasing radiative absorption due to abundance of anthropogenic greenhouse gases in the atmosphere and consequent warming, the emission of thermal energy from the atmosphere towards the surface is increasing (known as downward thermal radiation). This enhances the radiative energy surplus at the surface, and, where surface water is not limited, fuels evaporation besides warming the Earth's surface. The enhanced greenhouse effect therefore tends to accelerate the hydrological cycle, as also shown in many climate model simulations with increasing levels of greenhouse gases (e.g., IPCC 2007, but also see Yang et al 2003, Andrews et al 2009). We can assume that the increase in

    The broad dipolar magnetic anomaly whose positive peak is centered near Ejido Nuevo Leon, some 5 km east of the Cerro Prieto I Power Plant, has long been suspected to have a genetic relationship to the thermal source of the Cerro Prieto geothermal system. This suspicion was reinforced after several deep geothermal wells, drilled to depths of 3 to 3.5 km over the anomaly, intersected an apparent dike-sill complex consisting mainly of diabase but with minor rhyodacite. A detailed fit of the observed magnetic field to a computer model indicates that the source may be approximated by a tabular block 4 by 6 km in area, 3.7 km in depth, 2.3 km thick, and dipping slightly to the north. Mafic dike chips from one well, NL-1, were analyzed by means of electron microprobe analyses which showed tham to contain a titanomagnetite that is paramagnetic at in-situ temperature conditions. As the dike mineralogy does not account for the magnetic anomaly, the magnetic source is believed to be a deeper, magnetite-rich assemblage of peridotite-gabbro plutons. the suite of igneous rocks was probably passively emplaced at a shallow depth in response to crustal extension and thinning brought on by strike-slip faulting. The bottom of the magnetic source body, at an estimated depth of 6 km, is presumed to be at or near that of the Curie isotherm (575/sup 0/C) for magnetite, the principal ferromagnetic mineral in peridotitic-gabbroic rocks. The geological model derived from the magnetic study is generally supported by other geophysical data. In particular, earthquake data suggest dike injection is occurring at depths of 6 to 11 km in an area beneath the magnetic source. Thus, it is possible that heat for the geothermal field is being maintained by continuing crustal extension and magmatic activity.

    TIn the autumn of 2010 I became the Editor-in Chief of European Journal of Physics (EJP). EJP is a place for teachers, instructors and professors to exchange their views on teaching physics at university level and share their experience. It is general opinion that no good research is possible without connection with good, high-quality teaching, at the university level in particular. Therefore excellence in physics teaching is important to the physics community. European Journal of Physics is proud of its contribution to achieving this goal. As Editor-in-Chief, I will continue to work to this general objective of the journal. We will publish articles on specific topics in physics, stressing originality of presentation and suitability for use in students'laboratories, lectures and physics teaching in general. We will also publish more pedagogical papers presenting the achievements of particular teaching methods. In addition, we will continue to publish special sections on particular areas of physics, as well as the annual special section on physics competitions. European Journal of Physics is in good shape. Due to the work of the previous editors and the publisher, the readership is high and growing steadily, and many excellent papers are being submitted and published. I hope that this positive trend for the journal will continue, and I will do my best to keep to this high standard. A few words about myself. I work in the Institute of Physics in Warsaw, Poland. My main research interests are in theoretical quantum optics and I have published about 80 research papers on this topic. For many years I was involved in teaching physics at university and in high school. I am a co-author of a textbook on physics for high-school students and of a problem book in quantum mechanics. For the last ten years, I have been involved in the International Physics Olympiad and over the last few years I have been a member of the Editorial Board of European Journal of Physics.

    The Tibetan Plateau is one of the Earth's most sensitive regions in responding to climate change due to its extremely high altitude and the presence of permafrost and glaciers. The cryosphere, biosphere and hydrosphere of the plateau have been undergoing significant changes. Due to the low human population density, environmental changes on the plateau are largely driven by natural processes. Thus, the plateau provides a unique and comprehensive site for global change studies. This focus issue on Climate Change on the Tibetan Plateau aims to address both paleo and recent environmental changes across the plateau to facilitate our understanding of this remote and under-studied area. We invited a wide spectrum of contributions to address climate change, permafrost degradation, glacier/snow/ice dynamics, lake dynamics, land- cover/land-use changes, and their interactions on the plateau. Collectively, the diverse contributions in this special issue are expected to present the recent advancement of the above topics and beyond. See the PDF for the full text of the editorial.

    Antecedentes: la sensibilización a alergenos observada en la dermatitis atópica aumenta el riesgo del niño a padecer rinitis alérgica y asma. Los estudios recientes indican que entre mayor actividad de proteasas haya en los alergenos a los que se está sensibilizado, hay mayor defecto en la barrera cutánea y mayor gravedad de la enfermedad. Objetivos: conocer el patrón de sensibilización a los alergenos en niños con dermatitis atópica atendidos en el Servicio de Alergología del Hospital Universitario de la Universidad Autónoma de Nuevo León y conocer si estos niños tienen mayor sensibilización a los antígenos con actividad proteolítica. Material y método: estudio retrospectivo en el que revisamos los reportes de las pruebas cutáneas por punción realizadas en nuestro servicio a niños de 5 meses a 16 años de edad, con diagnóstico de dermatitis atópica, de enero de 2012 a enero de 2014. Evaluamos la frecuencia de sensibilización a aeroalergenos y alimentos, así como el tamaño de la roncha en la respuesta cutánea para cada alergeno en particular. Resultados: se incluyeron los reportes de pruebas cutáneas de 66 niños, 30 hombres y 36 mujeres. Cuarenta y seis pacientes estaban sensibilizados a aeroalergenos y 38 a alimentos. Los ácaros del polvo de casa (Dermatophagoides pteronyssinus/Dermatophagoides farinae) fueron los alergenos con mayor frecuencia de respuesta positiva en las pruebas cutáneas. De los niños con sensibilización a alimentos, sólo los niños sensibilizados a la leche de vaca, al huevo y al pescado tuvieron una roncha mayor de 6 mm de diámetro. CONCLUSIÓN: en los niños con dermatitis atópica es común la sensibilización a aeroalergenos con alta actividad de proteasas y la polisensibilización es muy común. La sensibilización a alimentos es común en estos pacientes, pero sólo un pequeño porcentaje de ellos muestra respuestas cutáneas lo suficientemente grandes para relacionarlas con gravedad de la enfermedad.

    During an ongoing physiological ecology study on pups and adult female northern elephant seals (Mirounga angustirostris, Gill, 1866) on the mainland rookery at Año Nuevo State Reserve (California), an opportunity was afforded to collect fresh dead pups for parasitology and necropsy. The investigation was undertaken to delineate the causes of death of northern elephant seals recovered from Año Nuevo State Reserve. Prior to this study, there was no evidence of increased mortality or health problems on this rookery. Necropsies, histology, and ancillary diagnostic studies were conducted on 21 fresh dead preweaned pups. Ages ranged from 1 stillbirth to pups approximately 2 weeks of age. Gross lesions included varying degrees of bruising, hemorrhage, lacerations, and fractures attributed to blunt force trauma to the head, chest, and/or abdomen in 16 pups; starvation in 6 pups; bite wounds in 2 pups; generalized icterus in 2 pups; presumptive drowning in 2 pups; and 1 stillbirth. Most pups had multiple gross lesions. Following light microscopic examination, pups could be assigned into 4 general diagnostic categories: 1) trauma, 2) nutritional status, 3) infectious conditions, and 4) congenital anomalies. This investigation of preweaned pup mortality of northern elephant seals in California further refines diagnostic categories for perinatal pup mortality.

    The publishers of Physics in Medicine and Biology (PMB), IOP Publishing, in association with the journal owners, the Institute of Physics and Engineering in Medicine (IPEM), jointly award an annual prize for the best paper published in PMB during the previous year. The procedure for deciding the winner has been made as thorough as possible, to try to ensure that an outstanding paper wins the prize. We started off with a shortlist of the 10 research papers published in 2010 which were rated the best based on the referees' quality assessments. Following the submission of a short 'case for winning' document by each of the shortlisted authors, an IPEM college of jurors of the status of FIPEM assessed and rated these 10 papers in order to choose a winner, which was then endorsed by the Editorial Board. We have much pleasure in advising readers that the Roberts Prize for the best paper published in 2010 is awarded to M M Paulides et al from Erasmus MC, Rotterdam, The Netherlands, for their paper on hyperthermia treatment: The clinical feasibility of deep hyperthermia treatment in the head and neck: new challenges for positioning and temperature measurement M M Paulides, J F Bakker, M Linthorst, J van der Zee, Z Rijnen, E Neufeld, P M T Pattynama, P P Jansen, P C Levendag and G C van Rhoon 2010 Phys.

    within their own areas of the field. Because that field is moving rapidly and has now become a major subject of study, we believe that a collection of updated reviews would be highly appropriate and beneficial to the community. We have been fortunate in getting the same authors to provide six-year updates of their original works. This offers continuity and also allows those who may be new to this area to refer back to the original reviews for a full description of the basic science. In the interests of economy and to avoid repetition, this new set of reviews should be read in conjunction with the original works. The Editorial Board of J. Phys D is particularly grateful to the authors for agreeing to write a second work for our journal. We are aware that the production of reviews is an onerous task and acknowledge their efforts in making available such clear and high quality papers. We trust these new works will prove as beneficial to readers and as successful for their authors as were their original reviews.

    Background Publication of clinical research findings in prominent journals influences health beliefs and medical practice, in part by engendering news coverage. Randomized controlled trials (RCTs) should be most influential in guiding clinical practice. We determined whether study design of clinical research published in high-impact journals influences media coverage. Methods and Findings We compared the incidence and amount of media coverage of RCTs with that of observational studies published in the top 7 medical journals between 1 January 2013 and 31 March 2013. We specifically assessed media coverage of the most rigorous RCTs, those with >1000 participants that reported ‘hard’ outcomes. There was no difference between RCTs and observational studies in coverage by major newspapers or news agencies, or in total number of news stories generated (all P>0.63). Large RCTs reporting ‘hard’ outcomes did not generate more news coverage than small RCTs that reported surrogate outcomes and observational studies (all P>0.32). RCTs were more likely than observational studies to attract a journal editorial (70% vs 46%, P = 0.003), but less likely to be the subject of a journal press release (17% vs 50%, P<0.001). Large RCTs that reported ‘hard’ outcomes did not attract an editorial more frequently than other studies (61% vs 58%, P>0.99), nor were they more likely to be the subject of a journal press release (14% vs 38%, P = 0.14). Conclusions The design of clinical studies whose results are published in high-impact medical journals is not associated with the likelihood or amount of ensuing news coverage. PMID:26701758

    We wish to draw the attention of authors to two points concerning the presentation of manuscripts. First, some changes have been made recently in our Instructions to Authors. We have reduced from two to one the number of duplicate copies of the manuscript required, asked for corrected proofs to be returned to the Editor rather than directly to the publishers, clarified that a single set of illustration-photographs will suffice, removed a specific suggestion for a style manual that we had offered for general guidance only, and added an instruction on conventions in spelling and hyphenation. Secondly, authors are required, of course, to present a thorough analysis of their experimental data and to include an estimate of their uncertainty. For this purpose, however, we strongly encourage the authors to follow the recommendations put forward by an international working group [1] to the Comité International des Poids et Mesures (CIPM) and endorsed by that body in its Recommandation 1 (CI-1981). This recommendation has been published by the CIPM [2] and was also summarized recently in this journal [3].

  20. EDITORIAL: Ultrafast magnetization processes

    NASA Astrophysics Data System (ADS)

    Hillebrands, Burkard

    2008-09-01

    This Cluster Issue of Journal of Physics D: Applied Physics is devoted to ultrafast magnetization processes. It reports on the scientific yield of the Priority Programme 1133 'Ultrafast Magnetization Processes' which was funded by the Deutsche Forschungsgemeinschaft in the period 2002-2008 in three successive two-year funding periods, supporting research of 17-18 groups in Germany. Now, at the end of this Priority Programme, the members feel that the achievements made in the course of the programme merit communication to the international scientific community in a concerted way. Therefore, each of the projects of the last funding period presents a key result in a published contribution to this Cluster Issue. The purpose of the funding by a Priority Programme is to advance knowledge in an emerging field of research through collaborative networked support over several locations. Priority Programmes are characterized by their enhanced quality of research through the use of new methods and forms of collaboration in emerging fields, by added value through interdisciplinary cooperation, and by networking. The aim of the Priority Programme 1133 'Ultrafast Magnetization Processes' may be well characterized by the call for projects in June 2001 after the programme was approved by the Deutsche Forschungsgemeinschaft: 'The aim of the priority programme is the achievement of a basic understanding of the temporal evolution of fast magnetization processes in magnetically ordered films, multilayers and micro-structured systems. The challenge lies in the advancement of the field of ultrafast magnetization processes into the regime of a few femtoseconds to nanoseconds, a topic not yet well explored. A general aim is to understand the fundamental mechanisms needed for applications in ultrafast magneto-electronic devices. The fundamental topic to be addressed is the response of the magnetization of small structures upon the application of pulsed magnetic fields, laser pulses or injected spin-polarized electron pulses on short time scales, ranging from a small disturbance of the system up to the reversal of the magnetization direction.' Now, seven years later, the subject of ultrafast magnetization processes has grown into a mainstream research direction in modern magnetism. The major international conferences on magnetism, such as the Annual Conference on Magnetism and Magnetic Materials (MMM), the INTERMAG, the International Conference of Magnetism, as well as many regional conferences, schedule dedicated sessions to ultrafast magnetization processes, very often several of them. The large share in research in this field from German scientists has been made possible by this Priority Programme. Since its beginning, new developments have been picked up by the Priority Programme 1133 and addressed by projects. Spin torque phenomena in spin dynamics, although foreseen at the time of establishing the Priority Programme, have been taken up. The field of dissipation has been addressed and extended by several groups, with contributions both from theoretical and experimental groups. A first set of contributions addresses ultrafast dynamics and materials. T Roth et al [article 164001] in this issue] study the dynamics of coercivity in ultrafast pump-probe experiments on the femtosecond time scale. They show that an all optical pump-probe technique is, in general, not suitable for gaining access to the time-dependent behaviour of the coercivity, since the switching in a fixed external field is an irreversible process. They comment on the possible mechanisms leading to the observed reduction of the coercivity with increasing pump power and propose a potential solution to clarify the origin of such a behaviour. B Heitkamp et al [164002] discuss the femtosecond spin dynamics of ferromagnetic CoPt thin films and nanodots, which they probe using spin-polarized photoemission electron microscopy. They show by photoelectron spin analysis, that enhanced optical near fields can be used to induce a local demagnetization of the sample following femtosecond laser excitation. A B Schmidt et al [164003] report a new access to the surface electronic structure of fcc Co films combining spin-resolved one- and two-photon photoemission. The knowledge of surface states is important for interpreting time-resolved measurements of ultrafast magnetization dynamics in this material. An extension of ultrafast dynamics has been made by several groups. A Melnikov et al [164004] report on the ultrafast dynamics at lanthanide surfaces such as Gd(0001) and Tb(0001) using time-resolved second-harmonic generation and photoelectron spectroscopy. These surfaces exhibit a rich dynamics including a collective response of the crystal lattice and the magnetization. Effects of phonon-magnon scattering are discussed. M Fiebig et al [164005] report on experiments of ultrafast magnetization dynamics in antiferromagnetic compounds, and show that the magnetization dynamics in these systems differs noticeably from that of ferromagnetic compounds. They use optical second-harmonic generation and linear reflection to monitor the evolution of the antiferromagnetic order parameter subsequent to an intense optical excitation. In a theory paper, the local light-induced spin manipulation in two-magnetic-centre metallic chains is studied by T Hardenstein et al [164006] using highly correlational ab initio calculations. They show that, as an example of local spin manipulation, the spin on the iron side of a Co-Na-Fe cluster can be switched. S Halm et al [164007] present evidence to manipulate spin states in a diluted magnetic semiconductor on a submicrometer length scale via the magnetic fringe fields of micro-structured magnets. By optically switching the magnetization of the ferromagnet, the magnetization in the semiconductor is manipulated and the limits of a dynamical interaction between the spin states in the ferromagnet and the magnetic semiconductor are discussed. A second set of contributions addresses the field of spin waves and dynamic spin torque phenomena. C W Sandweg et al [164008] discuss the modification of the thermal spin wave spectrum by a domain wall in a narrow stripe and report the observation of a localized mode near the domain wall using the new technique of Brillouin light scattering microscopy. Time-resolved measurements are often made using a stroboscopic approach, thus missing non-periodic responses. P Möhrke et al [164009] report single-shot Kerr magnetometer measurements to observe the real time-domain wall motion in permalloy nanowires. The dynamics in magnetic disks is studied by I Neudecker et al [164010] using in-plane magnetic microwave fields for excitation. The effect of current-induced magnetization dynamics in single and double layer magnetic nanopillars is reported by N Müsgens et al [164011]. A spin-polarized charge current can modify the damping properties of spin waves in magnetic nanostructures. This is reported by V E Demidov et al [164012] using space-resolved Brillouin light scattering. They also present results regarding nonlinear spin-wave propagation and mode coupling in magnetic stripes and squares. D V Berkov and N L Gorn [164013] report on their results of nonlinear magnetization dynamics in nanodevices induced by a spin-polarized current using micromagnetic simulation. A third set of contributions focuses on dissipation phenomena ranging from a phenomenological description to the investigation of the microscopic origin(s). In a theory paper, M Fähnle et al [164014] revisit the Gilbert equation and discuss anisotropic and non-local damping of the magnetization dynamics. They derive their results by a combination of the breathing Fermi surface model with a variant of the ab initio density functional electron theory given by the magnetic force theorem. On the experimental side, S Serrano-Guisan et al [164015] address Gilbert damping in Ni81Fe19 thin films and microstructures using anisotropic magnetoresistance and pulsed inductive microwave magnetometry to measure the time-resolved precessional magnetization dynamics. The intrinsic and non-local Gilbert damping in polycrystalline Ni films is also addressed by J Walowski et al [164016] using femtosecond laser pulses. Several spin-wave modes are observed and their dissipation is studied. Non-local damping by spin currents emitted into a non-magnetic metallic layer of either vanadium, palladium or dysprosium is studied. Dissipation in small magnetic Ni81Fe19 rings is studied using Brillouin light scattering microscopy by H Schultheiss et al [164017]. They investigate the spatial profiles and the decay constants of spin-wave quasi-eigenmodes. We hope that this cluster of papers will help to stimulate and advance a better understanding of this very interesting field of ultrafast magnetization processes.

    Nanomanufacturing is an essential bridge between the discoveries of nanoscience and real-world nanotech products and is the vehicle by which the world will realize the promise of major technological innovation across a spectrum of products that will affect virtually every industrial sector. For micro and nanotech products to achieve the broad impacts envisioned, they must be manufactured in market-appropriate quantities in a reliable, repeatable, economical and commercially viable manner. In addition, they must be manufactured so that environmental and human health concerns are met, worker safety issues are appropriately assessed and handled, and liability issues are addressed. Critical to this realization of robust manufacturing at the nanoscale is the development of the necessary instrumentation, metrology and standards, i.e. nanometrology. The National Measurement Laboratories are committed to developing the required metrology. Integration of the instruments, their interoperability and appropriate information management are also critical elements that must be considered for viable micro and nanomanufacturing. Advanced instrumentation, metrology and standards will allow the physical dimensions, properties, functionality and purity of the materials, processes, tools, systems, products and emissions that will constitute micro and nanomanufacturing to be measured and characterized. This will in turn enable production to be scalable, controllable, predictable and repeatable to meet market needs. If a product cannot be measured it cannot be manufactured; if that product cannot be made safely it should not be manufactured, and finally, if the metrology is not in place how would you know? The articles in this special feature can be classified into three categories: dimensional metrology (8 papers and one technical design note), density of particles (2 papers) and metrology of thermal properties (3 papers). The articles on dimensional metrology include scanning probe microscope dimensional metrology, the through focus scanning optical (TSOM) imaging method, scatterfield optical microscopy, helium ion microscopy, metrology and combinations of these microscopy and imaging techniques applied to nanostructures and particles such as cellulose nanocrystals, and targeted liposome-based delivery systems. Dimensional metrology covers grating pitch measurement by optical diffraction, measurement of the thickness of silicon oxide by synchrotron radiation x-ray photoelectron spectroscopy (SR-XPS) analysis and determination of pore size distribution of porous low-dielectric-constant films by x-ray scattering. The two papers on particle density present number concentration standards for aerosol nanoparticles of larger diameter than about 10 nm and liquid-borne particles in the range of 10-20 µm diameter, respectively. The three papers on metrology of thermal properties present recent innovative progress in thermophysical metrology of thin films by the ultrafast laser flash methods required for understanding of the thermal science at nanoscales and thermal design of nanodevices. The first paper improves the technology applicable under high pressures in a diamond anvil cell. The second extends this technology to thin films on silicon substrates. The third reports the first observation of non-diffusive heat transfer across thin films at low temperatures. In order to guarantee reliability and traceability of developed measurement methods for nanomaterials, a technical infrastructure for nanomaterials such as metrological standards, reference materials and document standards for measurement methods is important. We hope this special feature will be the first step in a collaboration towards a global harmonization of nanometrology.

    `May you live in interesting times' - old Chinese curse. First, many thanks to John Avison, the retiring Honorary Editor, for his hard work over the last five years, and the steady development in style and content under his stewardship. I can only hope to live up to the standards that he set. The next five years will take us into a new millenium, an event preceded - in England and Wales at least - by a period of stability, reflection and consolidation in education. Or so we are told - but whether such a self-denying ordinance will actually be maintained by the Government both before and after an election in 1997 remains to be seen. Nevertheless, we shall be thankful for any mercies, however small, that permit forward thinking rather than instant response. One of the things that readers of a journal called Physics Education should be thinking about is the continued decline in the numbers of students studying physics post-16. This is not a purely local phenomenon; most European countries are finding a similar decline. There are exceptions, of course: in Scotland numbers studying physics for Highers are increasing. Is such a decline a good thing or a bad thing? Only a minority of post-16 physics students go on to use the bulk of what they have learned in further studies or vocations. Does a knowledge and understanding of physics contribute to the mental well-being and cultural level - let alone material comfort - of any except those who use physics professionally? Is physics defensible as a contribution to the mental armoury of the educated citizen - compared with chemistry, biology - or Latin, say? Or should one rephrase that last question as `Is physics as we teach it today defensible...?' Such questions, and many others no doubt, may well be in the mind of the new Curriculum Officer appointed by the Institute of Physics `to engage in a wide-ranging consultation throughout the entire physics community on the nature and style of post-16 physics programmes, with a view to establishing a major curriculum development exercise on the scale of the Nuffield programmes of the 1960s'. The person appointed in this challenging role is the redoubtable Bryan Chapman (see his letter on page 14). I feel that readers of this journal constitute a well-informed section of the physics community and should be able to make a significant contribution to his work. I intend to use part of the July issue of Physics Education as a forum for views on the nature and style of post-16 (and even relevant pre-l6) physics programmes, both as they are and as they should be. The aim of the forum is not to provide solutions presented in lengthy, fully researched and well-argued articles but to raise ideas (and even expectations), to stimulate debate and set physics educators thinking creatively and radically about what might be an appropriate education in physics for the 2lst century. So send in your views - brief and to the point, trenchant and opinionated (all the more likely to be appreciated by Bryan C), anecdotal and theoretical, but preferably impregnated with the smell of chalk, wet blackboards, the sounds of wobbly-wheeled mechanics trolleys, quietly sizzling resistors and where necessary the heat of close encounters with the National Curriculum (version X) and/or GNVQs and the Subject Core for A-levels. Overseas readers - and Scots - may like to proffer advice based on their own, possibly less rebarbative, experiences. Don't hesitate: there is not a moment to be lost!

    2011-07-15

    Technological changes have moved publishing to electronic-first publication where the print version has been relegated to simply another display mode. Distribution in HTML and EPUB formats, for example, changes the reading environment and reduces the need for strict pagination. Therefore, in an effort to streamline the calculation of length, the APS journals will no longer use the printed page as the determining factor for length. Instead the journals will now use word counts (or word equivalents for tables, figures, and equations) to establish length; for details please see http://publish.aps.org/authors/length-guide. The title, byline, abstract, acknowledgment, and references will not be included in these counts allowing authors the freedom to appropriately credit coworkers, funding sources, and the previous literature, bringing all relevant references to the attention of readers. This new method for determining length will be easier for authors to calculate in advance, and lead to fewer length-associated revisions in proof, yet still retain the quality of concise communication that is a virtue of short papers.

    The APS journals receive manuscripts from scientists all over the world. For authors whose names cannot be expressed in Latin characters, their names in the byline must be transliterated, a process that is not necessarily bidirectionally unique. For example, the eight Chinese names all transliterate as Wei Wang. To remove some of the ambiguity arising from this unfortunate degeneracy of names, APS will allow some authors the option to include their names in their own language in parentheses after the transliterated name, such as Wei Wang. The option to present names in the article byline in this manner is an experiment initially offered to Chinese, Japanese, and Korean authors, whose names can be expressed in Unicode characters. An example of a Japanese name is Tadanori Minamisono and a Korean name is Chang Kee Jung. In the English text the given name precedes the family name, while the reverse is true for the characters. As we gain experience, we may be able to broaden this offer to other languages. Authors who wish to try this option will need to prepare their manuscripts by following the special instructions at http://authors.aps.org/names.html.

    Yoga therapy continues to flourish, thanks in part to the growing body of research evidence supporting its effectiveness in a variety of settings. This issue of IJYT advances the trend through articles that demonstrate the value of yoga therapy in improving the physical and psychological status of individuals with Parkinson's disease, in easing the transition of teenage girls from incarceration to participation in society, and in improving the flexibility of elderly individuals. As with the majority of articles accepted (and, alas, rejected) for acceptance into the Journal, the bulk of yoga therapy research has focused on the use of asana to address challenges ranging from the physical to the psychological.

    Blue or ultraviolet semiconducting light-emitting diodes have the potential to revolutionize illumination systems in the near-future. Such industrial need has propelled the investigation of several wide-gap semiconducting materials in recent years. Commercial applications include blue lasers for DVD memory and laser printers, while military applications are also expected. Most of the material development has so far been focused on GaN (band gap 3.5 eV at 2 K), and ZnSe (2.9 eV) because these two representative direct transition semiconductors are known to be bright emitting sources. GaN and GaN-based alloys are emerging as the winners in this field because ZnSe is subject to defect formation under high current drive. On the other hand, another II-VI compound, ZnO, has also excited substantial interest in the optoelectronics-oriented research communities because it is the brightest emitter of all, owing to the fact that its excitons have a 60 meV binding energy. This is compared with 26 meV for GaN and 20 meV for ZnSe. The stable excitons could lead to laser action based on their recombination even at temperatures well above room temperature. ZnO has additional major properties that are more advantageous than other wide-gap materials: availability of large area substrates, higher energy radiation stability, environmentally-friendly ingredients, and amenability to wet chemical etching. However, ZnO is not new to the semiconductor field as exemplified by several studies made during the 1960s on structural, vibrational, optical and electrical properties (Mollwo E 1982 Landolt-Boernstein New Series vol 17 (Berlin: Springer) p 35). In terms of devices, the luminescence from light-emitting diode structures was demonstrated in which Cu2O was used as the p-type material (Drapak I T 1968 Semiconductors 2 624). The main obstacle to the development of ZnO has been the lack of reproducible p-type ZnO. The possibility of achieving epitaxial p-type layers with the aid of thermal non-equilibrium growth has rekindled the recent extensive investigation and progress in the field of ZnO epitaxy. In this special issue, Ohtomo and Tsukazaki, Cho et al, and Yi et al, respectively, describe the various fabrication processes such as pulsed laser deposition, molecular-beam epitaxy and metal-organic chemical vapour deposition. It should be noted that the last work among the above-mentioned papers has the potential to pave the way to nano-technology based on ZnO. This material has found other important applications as well, such as transparent conducting oxides (TCO). This field has a long research history, as is reviewed by Minami. Relatively speaking, ZnO was one of the earliest crystals (after Si, Ge, and InSb) to be prepared in a pure form, and the resultant long research history has given rise to the availability of large-area substrates. Recent progress in this topic is explained by two representative groups of authors in this field: Nause and Nemeth at Cermet Inc., and Maeda et al at Tokyo Denpa Co. Ltd. In order to overcome the bottleneck of p-type conduction and control the material's properties, a clear understanding of the physical processes in ZnO is necessary. Look et al are known as the first group to report on the growth and properties of p-type ZnO layers with a valid and reasonable set of experimental data (2002 Appl. Phys. Lett. 81 1830). Here, Look contributes a more comprehensive review to this issue. Optical studies on single crystals were conducted and are reviewed here by Meyer et al and Chichibu et al. Band-gap engineering and fabrication of heterojunction or quantum structures are important technological issues. It should be emphasized that by choosing an appropriate set of concentrations (x and y), perfect lattice-matching between MgxZn1-xO and CdyZn1-yO can be attained (Makino T et al 2001 Appl. Phys. Lett. 78 1237). Exciton properties of multiple quantum well structures are reported by Makino et al in this issue. Other than growth of p-type layers, ferromagnetic behaviour in transition-metal doped oxide is also fuelling renewed interest from the spintronic point of view. Since some of the related reports remain controversial, a critical discussion of the magnetic properties of these doped oxides is made by Fukumura et al. Before the observation of electro-luminescence from the ZnO p-n homojunction reported by Tsukazaki et al (2005 Nature Mater. 4 42), the afore-mentioned advantages have been explored and exploited by alternative methods, such as heteroepitaxy in which p-n heterostructures can be obtained by depositing n-type ZnO films on other p-type oxides while still utilizing ZnO as their active layer. Researchers in Hosono's group observed the high-intensity band-edge emission from such heterostructures for the first time (Ohta H et al 2000 Appl. Phys. Lett. 77 475). They have also successfully extended their research fields to the development of a transparent oxide transistor based on homologous compounds, which is reviewed by Kamiya and Hosono in this special issue. As can be seen from these demonstrations, the advantage of oxides is, of course, based on the fact that many elements in the periodic table can form compounds with oxygen. Since the discovery of high-temperature superconductors, these multi-component oxides have exploited the new field known as the science of strongly correlated-electron materials, whose recent progress is reviewed by Inoue. Although the collection of papers included in this special issue covers a good cross-section of the development of oxide semiconductors and correlated-electron oxides to date, this is not meant to be exhaustive. There are a number of unavoidable omissions, such as theoretical studies except for some theoretical predictions on the room-temperature Bose-Einstein condensation of exciton-polaritons found in the article by Chichibu et al. We hope this issue promotes further development of this exciting field. The guest editors would like to thank the publishing team of Semiconductor Science and Technology at IoPP (Claire Bedrock, Barbara Bostock, Chris Hall, and Julie Stott).

    This Special Issue “Biodegradable Materials” features research and review papers concerning recent advances on the development, synthesis, testing and characterisation of biomaterials. These biomaterials, derived from natural and renewable sources, offer a potential alternative to existing non-biodegradable materials with application to the food and biomedical industries amongst many others. In this Special Issue, the work is expanded to include the combined use of fillers that can enhance the properties of biomaterials prepared as films. The future application of these biomaterials could have an impact not only at the economic level, but also for the improvement of the environment. PMID:25421242

  10. EDITORIAL: Photonic terahertz technology

    NASA Astrophysics Data System (ADS)

    Lisauskas, Alvydas; Löffler, Torsten; Roskos, Hartmut G.

    2005-07-01

    In recent years, when reading newspapers and journals or watching TV, one has been able to find feature presentations dealing with the prospects of terahertz (THz) technology and its potential impact on market applications. THz technology aims to fill the THz gap in the electro-magnetic spectrum in order to make the THz frequency regime, which spans the two orders of magnitude from 100 GHz to 10 THz, accessible for applications. From the lower-frequency side, electronics keeps pushing upwards, while photonic approaches gradually improve our technological options at higher frequencies. The popular interest reflects the considerable advances in research in the THz field, and it is mainly advances in the photonic branch, with the highlight being the development of the THz quantum cascade laser, which in recent years have caught the imagination of the public, and of potential users and investors. This special issue of Semiconductor Science and Technology provides an overview of key scientific developments which currently represent the cutting edge of THz photonic technology. In order to be clear about the implications, we should define exactly what we mean by 'THz photonic technology', or synonymously 'THz photonics'. It is characterized by the way in which THz radiation (or a guided THz wave) is generated, namely by the use of lasers. This may be done in one of two fundamentally different schemes: (i) by laser action in the terahertz frequency range itself (THz lasers), or (ii) by down-conversion processes (photomixing) involving the radiation of lasers which operate in the visible, near-infrared or infrared spectral ranges, either in pulsed or continuous-wave mode. The field of THz photonics has grown so considerably that it is out of the question to cover all its aspects in a single special issue of a journal. We have elected, instead, to focus our attention on two types of development with a potentially strong impact on the THz field: first, on significant advances of the technology itself, and second, on specific applications considered capable of fostering the transmutation of THz technology as a whole into a market technology. We decided for reasons of conciseness to leave out technologies which require more than table-top equipment (free-electron lasers, THz sources based on electrons accelerated to relativistic speed, etc) as well as fairly mature techniques (such as backward-wave oscillators which, although they are not strictly lasers, also exhibit gain). More difficult was the decision not to consider fascinating ideas for novel sources and detectors which until now have existed only on paper or have just entered the process of fundamental investigation. As we ourselves are working on such a concept (the Bloch-gain laser), we are fully aware of the fact that some of these ideas may have a strong impact on the field of THz photonics in the near future. After selection of the topics we wanted to cover, we contacted colleagues who are prominent in their respective fields of research and are grateful that most of them responded positively, expressing their willingness to share their knowledge with the readers of this journal. They took care not only to describe their own work but to give ample reference to the status of their respective specialized field of work. Before summarizing the contributions, we want to address all colleagues in the field who feel that they should have been asked to contribute but were not. To you we want to apologize. We can only hope for your understanding of the constraints of this endeavour. The collection of invited contributions is grouped into five topics. The first is entitled 'Pulsed THz Systems' and contains four papers dealing with the state of the art in source and detector development of measurement systems employing femtosecond Ti:sapphire lasers. The first paper, by Planken et al, describes the state of the art of the most common types of optoelectronic THz systems, namely those with femtosecond lasers operating at high repetition rate (~100 MHz). The system described by Planken et al was initially optimized for high-speed pixel-by-pixel THz imaging, which they do not describe here but rather focus on developments in THz microscopy. The second paper, by Kübler et al, presents pioneering work towards ultra-wide-bandwidth THz pulses which exhibit spectral content reaching far into the mid-IR, tremendously widening the covered frequency range, and hence shortening the time resolution, of THz spectroscopy. The third paper, by Löffler et al, deals with the state of the art in THz measurement systems relying on amplified laser pulses. Finally, Krotkus et al focus on low-temperature-grown (LT) GaAs, arguably the most important material for ultrafast optoelectronic switching and present in many THz sources and detectors, and in other emerging materials of similar kind. This leads directly to the second topic of this collection of papers, 'Continuous-Wave Photomixing Technology', based on THz-wave generation by down-conversion of continuous-wave (cw) laser radiation. This newer branch of THz photonics opens the possibility of obtaining tunable narrow-band THz radiation and of detecting it with high signal-to-noise ratio at room temperature. CW photomixing has received much attention over the last few years mainly because it has the potential to provide the compact and low-cost THz measurement systems needed for market applications beyond the scientific realm, with the sources of light for mixing being semiconductor (or fibre) lasers with or without optical amplifiers. Six papers outline recent developments in this subfield. We should also point towards a seventh paper, by Kawase et al, which is to be found in the section on 'Chemical and Biochemical Recognition', and which discusses an interesting hybrid approach generating tunable quasi-cw THz radiation with the help of nanosecond laser pulses. Of the six papers mentioned, the first, by Tani et al, summarizes the state of the art which relies on single-point LT-GaAs photoconductive antennae as THz sources and detectors driven by semiconductor lasers operating at wavelengths around 0.8 m. As laser-induced damage to the sources currently limits the achievable output power, researchers have early-on tried to develop travelling-wave mixers with distributed THz-power generation. Michael describes the status quo of this approach. The replacement of lifetime-limited photoconductive antennae with transit-time-limited p-i-n photomixers can be another way towards higher conversion efficiency if the RC frequency roll-off can be controlled. Döhler et al introduce a novel lumped-element device, a quasi-ballistic cascaded p-i-n photomixer, which promises a significantly better conversion efficiency than standard LT-GaAs photomixers at all frequencies. At laser wavelengths in the telecommunication windows, especially at 1.55 m, where InP-based compound semiconductors exhibit an extremely favourable electron mobility, p-i-n mixers have already established themselves as a powerful THz source. The group of Ito et al have set the standards here and describe their achievements in the fourth paper of this subtopic. The challenge remains to develop a similarly effective optoelectronic detector for these operating wavelengths. This, as Brown et al show in their contribution, turns out to be mainly a materials research issue, and as novel ultrafast materials such as those containing ErAs clusters emerge, so do sensitive detectors and photoconductive sources. The section closes with a paper by Hoffmann et al, which is more speculative in its scope but targets a fascinating goal: THz photomixing directly in a dual-colour semiconductor laser itself, and thus the ultimate miniaturization of a THz source based on photomixing. The third topic is 'THz Laser Technology' and addresses direct laser action at THz frequencies. Hübers et al guide the reader into the topic with a paper presenting the state of the art and the potential of lasers based on germanium and silicon. Tredicucci et al then review their development of the THz quantum cascade laser, the THz radiation source which more than any other currently transforms the field of THz technology. Their paper and the following one by Hu et al, who have introduced major improvements of the laser scheme and the waveguiding technology, present the state of the art of these lasers and discuss their future potential. One of the main challenges will be to raise the operation temperature further, and to bring it as close to room temperature as possible. These improvements will require a more advanced theoretical understanding of how these lasers work. The papers of Hu et al and the following one by Indjin et al address this question and describe the present status of theory. With this, we leave THz sources and detectors and come to research targeting the application of THz radiation. We have, given the space restraints and the fact that the focus of this journal is on semiconductor technology, decided to address only a single field of strong current interest, 'Chemical and Biochemical Recognition'. Other developing areas, such as THz radar and tomography, aiming at the sensing and diagnostics of surfaces and the inner structure of THz-transparent objects, or semiconductor wafer diagnostics and various other THz measurement modalities, are not covered. Not at all because we might consider them to be less important; quite on the contrary we are certain that they will make a big impact in real-world applications. The field of chemical and biochemical recognition was singled out because in the recent past there was controversial discussion as to what THz spectroscopic signatures to expect, especially from soft and solid chemical or biochemical matter, and the time seems to have come now to review some of the hard data obtained in the mean time. The topic covers the identification and analysis of chemical and biochemical substances, with a strong motivation stemming from the fact that the knowledge gained by this research opens up broad application areas in such lucrative markets as pharmaceutics, genetics, medical imaging and security screening. It may be interesting to note that until one or two years ago, a buzzword of applications-related research would have been 'biomedical imaging', especially of cancerous tissue or teeth, but for whatever reason none of the researchers contacted by us were interested to represent this subfield here, which seems to indicate that it is not considered to be a hot topic at present. The first two papers in this section, by Fischer et al and Shen et al, set the stage with an overview of chemical recognition in absorption and reflection spectroscopy, respectively. Kawase et al then demonstrate drug identification with their unique quasi-cw parametric THz system. While the scope of this paper is already security-oriented, Federici et al go further along this line by discussing not only drug detection but also sensing of explosives and weapons. The section closes with a paper by Nagel et al on the detection of DNA-binding states and on the system improvements implemented by this group on the way towards cost-effective sensing. This brings us to the final theme, 'THz Microscopy, Imaging, and Photonic Crystals'. The three papers in this section deal with three different aspects of THz technology which represent current progress in the use of THz radiation. The first paper, by Cho et al, as well as the one by Planken et al in the section on 'Pulsed THz Systems', discusses developments aiming towards THz microscopy, and reviews the latest results in achieving ultrahigh spatial resolution at THz frequencies. The next paper, by Karpowicz et al, comes back to the issue of THz imaging, which was already addressed by authors of papers in the preceding section, and presents a systematic comparison between two imaging and sensing modalities, time-domain optoelectronic imaging and more conventional GHz all-electronic imaging. This study of high practical interest is followed by the final contribution, by Jian et al, which discusses the development and characterization of photonic crystals for THz frequencies. We hope that this special issue will provide the readers of this journal with a good overview of the current status of THz photonics. We also hope that we, the Guest Editors and the authors of the papers, will succeed in conveying the fascination of this field of research which comes equally from its interdisciplinarity and from the fact that fundamental and applied research go hand in hand, strongly impacting on each other. For those working in this field it is highly gratifying to help make the last under-used window of the electro-magnetic spectrum accessible for applications.

    Four examples show how academic freedom has come under heavy attack during the 20th century. Yet some scholars say they do not care about academic freedom. Perhaps the greatest danger to academic freedom does not come from scholars who advocate extreme views or assert their right to academic freedom, but from those who are apathetic or cowardly.…

    This special issue on Polarization Optics contains one review article and 23 research papers, many of which are based on presentations at the International Commission for Optics Topical Meeting on Polarization Optics, held in Polvijärvi, Finland, between 30 June and 3 July 2003. While this issue should not in any sense be considered as a `proceedings' of this meeting, the possibility of submitting papers to it was widely advertised during the meeting, which was attended by a large fraction of prominent scientists in the field of polarization optics. Thus the quality of papers in this special issue is high. In announcing both the meeting and this special issue, we emphasized that the concept of `polarization optics' should be understood in a wide sense. In fact, all contributions dealing with the vectorial nature of light were welcome. As a result, the papers included here cover a wide range of different aspects of linear and nonlinear polarization optics. Both theoretical and experimental features are discussed. We are pleased to see that the conference and this special issue both reflect the wide diversity of important and novel polarization phenomena in optics. The papers in this special issue, and other recently published works, demonstrate that even though polarization is a fundamental property of electromagnetic fields, interest in it is rapidly increasing. The fundamental relations between partial coherence and partial polarization are currently under vigorous research in electromagnetic coherence theory. In diffractive optics it has been found that the exploitation of the vectorial nature of light can be of great benefit. Fabrication of sophisticated, spatially variable polarization-control elements is becoming possible with the aid of nanolithography. Polarization singularities and the interplay of bulk properties and topology in nanoscale systems have created much enthusiasm. In nonlinear optics, the second harmonic waves generated on reflection and transmission of intense light enable research into the chirality of nanogratings. Pump-probe techniques allow one to visualize the effects of the nanostructure topology on the surface mode excitation. In quantum optics the coherent control of polarization may lead to new and fascinating applications. Some authors of invited papers at the conference have written review-type introductory sections—they were encouraged to do so—but all contributions are genuine research papers with original results, and were judged according to the normal publication criteria of the journal. It is our pleasure to thank all authors for making this a splendid special issue of Journal of Optics A: Pure and Applied Optics.

    Extra-territorial readers of this journal must surely hover between amazement and boredom at the periodic references to the time and energy spent in England in reviewing, changing, re-reviewing and re-changing its educational programmes from ages 5-18. (Scotland has its own educational system and seems to be doing quite well, thank you.) Recently, Sir Ron Dearing, the Government's educational trouble-shooter, who in a few short months managed to sort out the 5-16 curriculum to the satisfaction (more or less) of both Establishment and politicians, was given the task of redefining the principles underlying the education of 16-19 year-olds. In March 1996 he produced a report that has been greeted, initially at least, with the universal approval of the press and politicians of all parties. The main and century-old problem with the English educational system is the deep divide between academic (pre-university) and vocational education. This may reflect the broad division between `gentlemen' and players (artisans) that seems to be a feature of English society, and which may be too wide for a mere education system to bridge. A second problem has been the perceived narrowness, due to overspecialization into just three subjects, of pre-university courses, which has tended to produce yet another divide - between arts graduates (interesting, lively, well-read, cultured) and science graduates (boring, uncouth, illiterate). However, the rather boringly titled Review of Qualifications for 16-19 Year Olds, Summary ReportFootnote is at least clear in its intentions of bridging both gaps. It reviews the continuing decline in the popularity of mathematics and science subjects as pre-university (A-level) courses, and records that the parallel vocational courses (GNVQ) in science do not yet match their status and their acceptance by employers, and people in general. It accepts the failure of Advanced Supplementary courses to provide a broadening of the 16-19 curriculum. It makes many recommendations which will need very careful and intelligent management if they are to be both workable and beneficial; unfortunately recent history tells us that the Government's agencies responsible for educational management are insensitive to the advice of practitioners and work to hidden political agendas based on prejudgement if not downright prejudice. The Report's recommendations certainly provide a challenge for post-16 physics, especially for A-level. It is to be hoped that the new structures and initiatives of the Institute of Physics will be able to play a full part in ensuring that changes are beneficial and workable. Firstly, Sir Ron wants A-levels to provide opportunities and contexts for the development of some general skills, identified as communication (both written and oral), numeracy and in information technology, with a less clear reference to an ability to work as part of a team. Challenge 1: find good contexts in physics for these - and a valid assessment system. Secondly, the curriculum should be broadened by a kind of two-phase approach to post-16 studies. Potential A-level students would spend a year studying as many as six Advanced Subsidiary level subjects, chosen from four main areas: science, maths and technology; modern languages; arts and humanities; `the way the community works' (business, economics, law, psychology etc). Each new-style AS would be the first half of an A-level course. The second phase would allow specialization into, say, three A-levels as at present, or to a combination of A and AS courses. Challenge 2: design a half course that makes sense, and is as useful to potential lawyers as to potential physicists. Thirdly, there should be an increase in the size of the A-level subject cores. Challenge 3: design such an extended core that is less boringly old-fashioned than the current one (not too difficult, that) and is capable of useful fission (see Challenge 2). This is a good opportunity to consider the nature of a `core' in physics for such a wide variety of intended learners. A sheer increase in content would be a primitive and profoundly unsmart response. A fourth recommendation is that the number of physics syllabuses should be reduced. Challenge 4: design criteria for the selection of syllabuses thought worthy to survive. There are in fact quite a few other interesting recommendations, in particular dealing with mathematics and mathematics for physics, and a whole set of recommendations for a new national award system, recognizing achievement at all levels from sub-GCSE to A-level/GNVQ/NVQ Level 3. It's all very interesting and might indeed be very good. But can the bureaucrats manage it? ...Report ISBN 1 85838 1029, SCAA Publications, PO Box 235, Hayes, Middlesex UB3 1HF.

    We live in a highly materialistic age. This is true not only for our spiritual outlook - or lack of it - but undeniably so for the physical world in which we live. Materials, which are the feature of this special issue, provide literally the fabric on which the modern world is built. Materials science is the systematic study of the physical properties and behaviour of solids with practical applications and importance (if the utility of the material is not explicit or important we are probably in the realm of solid state physics!). Materials in this sense are the stuff of which cars and computers, jet aircraft and washing machines, tower blocks and saucepans, bridges and golf clubs are made. The science of materials therefore encompasses most of the things that form the infrastructure of modern life. But perhaps it is its very ubiquity that removes the mystique, the glamour, the 'zing' from the subject. In contrast, anything cosmological, astronomical or 'fundamental' (as in 'particle'), i.e. of little or no practical significance to our day-to-day lives, excites the curiosity of many able young people. Witness the profusion of books about galaxies and black holes, and quarks and GUTs which strain the popular science shelves of the bookshops. I'm probably being heretical, but perhaps the over-hyping of the very large and the very small has indeed attracted the able few into the serious study of physics, but because of its inherent mathematical complexity and esoteric remoteness maybe it has put off the average youngster who would nevertheless enjoy and succeed in physics-based higher education (and, not incidentally, help fill the seriously depleted lecture theatres in many university physics - and engineering - departments). Materials science on the other hand deals with an intermediate range of things which, give or take an order of magnitude or three, are person-sized as well as person useful. It is - therefore? - undoubtedly one of the less glamorous of the areas of physics-based science and technology. Can materials science be made intellectually more exciting and mind-stretching for our students? In this special issue we present several articles by researchers in less-than-familiar but important areas of materials science and technology. Following a review by Mathew Philip of some of the basic atomic theory which underlies materials science, Jose Silva looks at how artificial diamonds can be made and at how we can apply this exotic material (other than on fingers and around necks). Alan Piercy reviews the field of giant magnetostrictive materials, which, when magnetized, change dimensions hundreds or even thousands of times more than traditional ferromagnetics. David Pettifor provides a nicely interdisciplinary overview of how computer simulations, from the subatomic to the macroscopic level, can be used to help in the design of new materials for such things as turbine blades. Adrian Rennie offers a much-requested written version of the entertaining 1995/6 IOP Schools Lecture on the physics of polymers. (We had hoped to include an article by Professor Colin Gough of Birmingham University on High Temperatue Superconductors, but for technical reasons this has had to be postponed until a future issue.) Finally, there are two articles describing an initiative which will have a direct practical impact on the teaching and learning of `Materials' in the UK. Karen Davies describes the exciting new Materials Gallery due to be opened at the Science Museum as this issue goes to press in May 1997 (no coincidence!), and David Sang provides details of how the new gallery has been linked directly with the GNVQ curriculum, and can certainly be exploited more widely in our physics and technology teaching. Perhaps this can help provide the missing 'zing' that materials science at present seems to lack.

    If you were a caring, thinking, liberally minded person in the 1960s, you marched against the bomb, against the Vietnam war, and for civil rights. By the 1980s, your voice was raised about the destruction of the rainforests and the threat to our whole planetary environment. At the same time, you opposed discrimination against any group because of race, sex or sexual orientation. You reasoned that people who spoke or acted in a discriminatory manner should be discriminated against. In other words, you became politically correct. Despite its oft-quoted excesses, the political correctness movement sprang from well-founded concerns about injustices in our society. So, on balance, I am all for it. Or, at least, I was until it started to invade science. Biologists were the first to feel the impact. No longer could they refer to 'higher' and 'lower' orders, or 'primitive' forms of life. To the list of undesirable 'isms' - sexism, racism, ageism - had been added a new one: speciesism. Chemists remained immune to the PC invasion, but what else could you expect from a group of people so steeped in tradition that their principal unit, the mole, requires the use of the thoroughly unreconstructed gram? Now it is the turn of the physicists. This time, the offenders are not those who talk disparagingly about other people or animals, but those who refer to 'forms of energy' and 'heat'. Political correctness has evolved into physical correctness. I was always rather fond of the various forms of energy: potential, kinetic, chemical, electrical, sound and so on. My students might merge heat and internal energy into a single, fuzzy concept loosely associated with moving molecules. They might be a little confused at a whole new crop of energies - hydroelectric, solar, wind, geothermal and tidal - but they could tell me what devices turned chemical energy into electrical energy, even if they couldn't quite appreciate that turning tidal energy into geothermal energy wasn't part of the same game. In today's PC physics, no such complications arise because all forms of energy are equal and unlabelled. I accept the reasoning behind this - that understanding processes is more important than attaching labels - but what am I supposed to call ½mv2, mgh and mcΔθ? On which subject.... What am I allowed to say about heat? It seems that objects can be heated up. I can switch on the central heating. But I cannot get heat from a Bunsen burner. In PC physics, heat is banned - at least as a noun. Instead, I have to talk about 'energy transferred because of a temperature difference'. And I must stop saying 'transferred' in circumstances where I really mean 'transformed'. I find it difficult to argue with the logic behind the new approach to energy, but the loss of such an elegantly simple word as 'heat' is proving a severe restriction on my use of language. The loss is especially galling because engineers will go on talking about heat engines, heat pumps and heat sinks. In primary schools, saucepans will still conduct heat, and the Sun will continue to give off heat and light. Moreover, I suspect that most teachers will be using 'heat' in the privacy of the classroom, even if they won't admit to it in public. We shall all become closet heatists. Before PC physics takes over by stealth, we need a full and open debate on what is or isn't conceptually acceptable for students at different stages. Perhaps we need a conference. If so, I will be there at the back with my banner. But this time, it won't read 'Save the whale' or 'Save the rainforests'. It will read 'Save heat', or maybe 'Save all forms of energy'.

    'Molecular Imaging Technology' focuses on image-based techniques using nanoscale molecules as sensor probes to measure spatial variations of various species (molecular oxygen, singlet oxygen, carbon dioxide, nitric monoxide, etc) and physical properties (pressure, temperature, skin friction, velocity, mechanical stress, etc). This special feature, starting on page 1237, contains selected papers from The International Workshop on Molecular Imaging for Interdisciplinary Research, sponsored by the Ministry of Education, Culture, Sports, Science and Technology (MEXT) in Japan, which was held at the Sendai Mediatheque, Sendai, Japan, on 8 9 November 2004. The workshop was held as a sequel to the MOSAIC International Workshop that was held in Tokyo in 2003, to summarize the outcome of the 'MOSAIC Project', a five-year interdisciplinary project supported by Techno-Infrastructure Program, the Special Coordination Fund for Promotion of Science Technology to develop molecular sensor technology for aero-thermodynamic research. The workshop focused on molecular imaging technology and its applications to interdisciplinary research areas. More than 110 people attended this workshop from various research fields such as aerospace engineering, automotive engineering, radiotechnology, fluid dynamics, bio-science/engineering and medical engineering. The purpose of this workshop is to stimulate intermixing of these interdisciplinary fields for further development of molecular sensor and imaging technology. It is our pleasure to publish the seven papers selected from our workshop as a special feature in Measurement and Science Technology. We will be happy if this issue inspires people to explore the future direction of molecular imaging technology for interdisciplinary research.

    2007-04-01

    Microwave moisture measurements refer to a methodology by which the water content of materials is non-invasively determined using electromagnetic fields of radio and microwave frequencies. Being the omnipresent liquid on our planet, water occurs as a component in most materials and often exercises a significant influence on their properties. Precise measurements of the water content are thus extremely useful in pure sciences, particularly in biochemistry and biophysics. They are likewise important in many agricultural, technical and industrial fields. Applications are broad and diverse, and include the quality assessment of foodstuffs, the determination of water content in paper, cardboard and textile production, the monitoring of moisture in sands, gravels, soils and constructions, as well as the measurement of water admixtures to coal and crude oil in reservoirs and in pipelines. Microwave moisture measurements and evaluations require insights in various disciplines, such as materials science, dielectrics, the physical chemistry of water, electrodynamics and microwave techniques. The cooperation of experts from the different fields of science is thus necessary for the efficient development of this complex discipline. In order to advance cooperation the Workshop on Electromagnetic Wave Interaction with Water and Moist Substances was held in 1993 in Atlanta. It initiated a series of international conferences, of which the last one was held in 2005 in Weimar. The meeting brought together 130 scientists and engineers from all over the world. This special issue presents a collection of some selected papers that were given at the event. The papers cover most topics of the conference, featuring dielectric properties of aqueous materials, electromagnetic wave interactions, measurement methods and sensors, and various applications. The special issue is dedicated to Dr Andrzej W Kraszewski, who died in July 2006 after a distinguished career of 48 years in the research of microwave applications. Dr Kraszewski was a pioneer in moisture content sensing and the founder of microwave aquametry. He organized the first conferences on electromagnetic wave interactions with water and moist substances and helped to maintain the progress of microwave aquametry research internationally. Andrzej Kraszewski is missed by the microwave moisture measurement community who appreciated both his unusual technical ability and his pleasant and endearing character. Andrzej W Kraszewski, 1933-2006 We hope you will enjoy reading these papers and will extend your scientific curiosity to this field. Finally, we would like to thank all the authors, referees and the staff of Measurement Science and Technology for their contributions and support which have made the publication of this special issue possible.

    There has been tremendous development within measurement science and technology over the past couple of decades. New sensor technologies and compact versatile signal recovery electronics are continuously expanding the limits of what can be measured and the accuracy with which this can be done. Miniaturization of sensors and the use of nanotechnology push these limits further. Also, thanks to powerful and cost-effective computer systems, sophisticated measurement and reconstruction algorithms previously only accessible in advanced laboratories are now available for in situ online measurement systems. The process industries increasingly require more process-related information, motivated by key issues such as improved process control, process utilization and process yields, ultimately driven by cost-effectiveness, quality assurance, environmental and safety demands. Industrial process tomography methods have taken advantage of the general progress in measurement science, and aim at providing more information, both quantitatively and qualitatively, on multiphase systems and their dynamics. The typical approach for such systems has been to carry out one local or bulk measurement and assume that this is representative of the whole system. In some cases, this is sufficient. However, there are many complex systems where the component distribution varies continuously and often unpredictably in space and time. The foundation of industrial tomography is to conduct several measurements around the periphery of a multiphase process, and use these measurements to unravel the cross-sectional distribution of the process components in time and space. This information is used in the design and optimization of industrial processes and process equipment, and also to improve the accuracy of multiphase system measurements in general. In this issue we are proud to present a selection of the 145 papers presented at the 5th World Congress on Industrial Process Tomography in Bergen, September 2007. Interestingly, x-ray technologies, one of the first imaging modalities available, keep on moving the limits on both spatial and temporal measurement resolution; experimental results of less than 100 nm and several thousand frames/s are reported, respectively. Important progress is demonstrated in research and development on sensor technologies and algorithms for data processing and image reconstruction, including unconventional sensor design and adaptation of the sensors to the application in question. The number of applications to which tomographic methods are applied is steadily increasing, and results obtained in a representative selection of applications are included. As guest editors we would like express our appreciation and thanks to all authors who have contributed and to IOP staff for excellent collaboration in the process of finalizing this special feature.

    Wind energy is rapidly growing. In 2006 the installed generating capacity in the world increased by 25%, a growth rate which has more or less been sustained during the last decade. And there is no reason to believe that this growth will slow significantly in the coming years. For example, the United Kingdom's goal for installed wind turbines by 2020 is 33 GW up from 2 GW in 2006, an average annual growth rate of 22% over that period. More than half of all turbines are installed in Europe, but United States, India and lately China are also rapidly growing markets. The cradle of modern wind energy was set by innovative blacksmiths in rural Denmark. Now the wind provides more than 20% of the electrical power in Denmark, the industry has professionalized and has close ties with public research at universities. This focus issue is concerned with research in wind energy. The main purposes of research in wind energy are to: decrease the cost of power generated by the wind; increase the reliability and predictability of the energy source; investigate and reduce the adverse environmental impact of massive deployment of wind turbines; build research based educations for wind energy engineers. This focus issue contains contributions from several fields of research. Decreased costs cover a very wide range of activities from aerodynamics of the wind turbine blades, optimal site selection for the turbines, optimization of the electrical grid and power market for a fluctuating source, more efficient electrical generators and gears, and new materials and production techniques for turbine manufacturing. The United Kingdom recently started the construction of the London Array, a 1 GW off-shore wind farm east of London consisting of several hundred turbines. To design such a farm optimally it is necessary to understand the chaotic and very turbulent flow downwind from a turbine, which decreases the power production and increases the mechanical loads on other nearby turbines. Also addressed within the issue is how much conventional power production can be replaced by the ceaseless wind, with the question of how Greece's target of 29% renewables by 2020 is to be met efficiently. Other topics include an innovative way to determine the power curve of a turbine experimentally more accurately, the use of fluid dynamics tools to investigate the implications of placing vortex generators on wind turbine blades (thereby possibly improving their efficiency) and a study of the perception of wind turbine noise. It turns out that a small but significant fraction of wind turbine neighbours feel that turbine generated noise impairs their ability to rest. The annoyance is correlated with a negative attitude towards the visual impact on the landscape, but what is cause and effect is too early to say. As mentioned there is a rush for wind turbines in many countries. However, this positive development for the global climate is currently limited by practical barriers. One bottleneck is the difficulties for the sub-suppliers of gears and other parts to meet the demand. Another is the difficulties to meet the demand for engineers specialized in wind. For that reason the Technical University of Denmark (DTU) recently launched the world's first Wind Energy Masters Program. Here and elsewhere in the world of wind education and research we should really speed up now, as our chances of contributing to emission free energy production and a healthier global climate have never been better.

    Imitating nature's mechanisms offers enormous potential for the improvement of our lives and the tools we use. This field of the study and imitation of, and inspiration from, nature's methods, designs and processes is known as biomimetics. Artificial muscles, i.e. electroactive polymers (EAPs), are one of the emerging technologies enabling biomimetics. Polymers that can be stimulated to change shape or size have been known for many years. The activation mechanisms of such polymers include electrical, chemical, pneumatic, optical and magnetic. Electrical excitation is one of the most attractive stimulators able to produce elastic deformation in polymers. The convenience and practicality of electrical stimulation and the continual improvement in capabilities make EAP materials some of the most attractive among activatable polymers (Bar-Cohen Y (ed) 2004 Electroactive Polymer (EAP) Actuators as Artificial Muscles—Reality, Potential and Challenges 2nd edn, vol PM136 (Bellingham, WA: SPIE Press) pp 1-765). As polymers, EAP materials offer many appealing characteristics that include low weight, fracture tolerance and pliability. Furthermore, they can be configured into almost any conceivable shape and their properties can be tailored to suit a broad range of requirements. These capabilities and the significant change of shape or size under electrical stimulation while being able to endure many cycles of actuation are inspiring many potential possibilities for EAP materials among engineers and scientists in many different disciplines. Practitioners in biomimetics are particularly excited about these materials since they can be used to mimic the movements of animals and insects. Potentially, mechanisms actuated by EAPs will enable engineers to create devices previously imaginable only in science fiction. For many years EAP materials received relatively little attention due to their poor actuation capability and the small number of available materials. In the last fifteen years, a series of new materials have emerged that exhibit large displacement in response to electrical stimulation. This capability is making them highly attractive as actuators for their operational similarity to biological muscles, particularly their resilience, quiet operation, damage tolerance and ability to induce large actuation strains (stretching, contracting or bending). The application of these materials as actuators involves multi-disciplines including materials, electromechanics, chemistry, computers and electronics. Even though the force of actuation of existing EAP materials and their robustness requires further improvement, there has already been a series of reported successes in the development of EAP-actuated mechanisms. Using EAP to replace existing actuators may be a difficult challenge and therefore it is highly desirable to identify a niche application where EAP materials would not need to compete with existing technologies. EAP materials can be divided into two major groups based on their activation mechanism: ionic or electronic. Electronic EAPs, such as electrostrictive, electrostatic, piezoelectric and ferroelectric, are driven by Coulomb forces. These types of EAP material can be made to hold the induced displacement while activated under a DC voltage, allowing them to be considered for robotic applications. These materials have high mechanical energy density and they can be operated in air with no major constraints. However, electronic EAPs require high activation fields (>10 V/μm) that are close to the breakdown level. In contrast to electronic EAPs, ionic EAPs are materials that involve the transport of ions and they consist of two electrodes and an electrolyte. The activation of ionic EAPs can be achieved by voltages as low as 1-2 volts. Examples of ionic EAPs include gels, polymer-metal composites, conducting polymers and carbon nanotubes. Their disadvantages are a need to maintain wetness and their low electromechanical coupling. Turning EAP materials into actuators-of-choice requires a well established infrastructure. This involves improving the understanding of the basic principles that drive the various EAP materials. It is also necessary to develop a comprehensive material science, as well as effective electro-mechanics analytical tools and material processing techniques. Efforts are underway to study the parameters that control EAP electro-activation force and deformation and many successes have been reported. The processes of synthesizing, fabricating, electroding, shaping and handling are being refined to maximize the actuation capability and robustness of EAP materials. Methods of reliably characterizing the response of these materials are being developed and efforts are being made to establish a database with documented material properties in order to support design engineers who are considering the use of these materials. Grand challenge for the development of EAP-actuated robotics. The technology of artificial muscles is still in its emerging stages but the increased resources, growing number of investigators conducting research related to EAP, and improved collaboration among developers, users and sponsors are leading to rapid advances in this field. In 1999, in an effort to promote worldwide development towards the realization of the potential of EAP materials, Yoseph Bar-Cohen posed an arm-wrestling challenge (http://ndeaa.jpl.nasa.gov/nasa-nde/lommas/eap/EAP-armwrestling.htm). A graphic rendering of this challenge is illustrated in the above figure. In posing this challenge, he is seeking to see an EAP-activated robotic arm win against a human in a wrestling match in order to provide a gauge of the level of advances in the development of these materials. Success in wrestling against humans will enable capabilities that are currently considered impossible. It would allow applying EAP materials to improve many aspects of our life where some of the possibilities include effective implants and prosthetics, active clothing and realistic biologically inspired robots, as well as fabricating products with unmatched capabilities and dexterity. The first arm-wrestling match against a human (a 17 year-old female high school student) was held on 7 March 2005 as part of the EAP-in-Action session of SPIE's EAPAD conference. Three robotic arms participated in the contest and the girl won against all these arms. Subsequent contests are now focusing on measuring the performance of the robotic arms compared to the student performance that was recorded in the 2006 contest. In a future conference, once advances in developing such arms reach a sufficiently high level, a professional wrestler will be invited for the next human/machine wrestling match. This issue of the journal is dedicated to publishing recent research advances in the field of EAPs and is the first such dedicated issue ever to be published. The included papers cover the whole spectrum of elements considered critical to the development of the EAP technology infrastructure. The issue ends with a paper from the research group at EMPA describing their work on one of the first three arms that participated in the first historical arm-wrestling match. In the coming year the editors are hoping to see a significant growth in the amount of research and related publications addressing the many challenges that this field still poses.

    Graphene physics is currently one of the most active research areas in condensed matter physics. Countless theoretical and experimental studies have already been performed, targeting electronic, magnetic, thermal, optical, structural and vibrational properties. Also, studies that modify pristine graphene, aiming at finding new physics and possible new applications, have been considered. These include patterning nanoribbons and quantum dots, exposing graphene's surface to different chemical species, studying multilayer systems, and inducing strain and curvature (modifying in this way graphene's electronic properties).

    En esta investigacion, se desarrollo un instrumento que permite medir percepciones relacionadas al contexto de constriccion del conocimiento cientifico. Se examinaron instrumentos existentes y se encontro que el VOSTS (Views on science, technology, and society), instrumento desarrollado empiricamente en Canada por Aikenhead, Ryan y Fleming, podia traducirse y validarse en el contexto cultural puertorriqueno. El instrumento es extenso, consta de 113 reactivos, cada uno con una premisa basica relacionada a la tematica ciencia, tecnologia y sociedad y un numero de alternativas relacionadas a la premisa que oscila entre siete y trece. Se delimito su utilizacion a los quince reactivos identificados por los autores como relacionados a la construccion social del conocimiento cientifico. Metodologicamente, se procedio a utilizar el modelo de adaptacion intercultural, que permite que el instrumento desarrollado satisfaga las dimensiones de equivalencia semantica, de contenido, tecnica, de criterio y conceptual, atemperado asi al instrumento original. Se cumplio con este proposito mediante la traduccion de la version original en ingles al espanol y viceversa. Se utilizaron comites para examinar la traduccion y la retro-traduccion del instrumento. Se realizo una prueba piloto con estudiantes universitarios de nuevo ingreso, utilizando el instrumento traducido para asegurar su intelegibilidad. La confiabilidad del instrumento se determino mediante la intervencion de un panel de expertos quienes clasificaron las distintas posiciones dentro de cada reactivo en: realista, con merito e ingenua; se transformaron estas opciones en valores numericos lo que permitio establecer una escala Likert para cada una. Se suministro el instrumento a una muestra de estudiantes universitarios de nuevo ingreso con caracteristicas similares a las de la poblacion puertorriquena en cuanto a ejecucion en las pruebas de aptitud verbal y matematica del College Board.

    Since 1991, Measurement Science and Technology has awarded a Best Paper prize. The Editorial Board of this journal believe that such a prize is an opportunity to thank authors for submitting their work, and serves as an integral part of the on-going quality review of the journal. The current breadth of topical areas that are covered by MST has made it advisable to expand the recognition of excellent publications. Hence, since 2005 the Editorial Board have presented 'Outstanding Paper Awards'. This year awards were presented in the areas of 'Measurement Science', 'Fluid Mechanics' and 'Precision Measurement'. Although the categories mirror subject sections in the journal, the Editorial Board consider articles from all categories in the selection process. 2011 Award Winners—Measurement Science Simultaneous measurement of internal and surrounding flows of a moving droplet using multicolour confocal micro-particle image velocimetry (micro-PIV) M Oishi, H Kinoshita, T Fujii and M Oshima Institute of Industrial Science, The University of Tokyo, 4-6-1 Komaba, Meguro-Ku, Tokyo 153-8505, Japan Interfaculty Initiative in Information Studies, The University of Tokyo, 4-6-1 Komaba, Meguro-Ku, Tokyo 153-8505, Japan Whilst the award last year [1] was concerned with the application of microscopy to ultra-high vacuum dynamic force measurements, this year's award [2] goes to another micro-measurement technique, one concerned with measurements related to particle image velocimetry.

    The last five years have witnessed an amazing development in the field of nano- and micromechanics. What was widely considered fantasy ten years ago is about to become an experimental reality: the quantum regime of mechanical systems is within reach of current experiments. Two factors (among many) have contributed significantly to this situation. As part of the widespread effort into nanoscience and nanofabrication, it is now possible to produce high-quality nanomechanical and micromechanical resonators, spanning length scales of millimetres to nanometres, and frequencies from kilohertz to gigahertz. Researchers coupled these mechanical elements to high-sensitivity actuation and readout systems such as single-electron transistors, quantum dots, atomic point contacts, SQUID loops, high-finesse optical or microwave-cavities etc. Some of these ultra-sensitive readout schemes are in principle capable of detection at the quantum limit and a large part of the experimental effort is at present devoted to achieving this. On the other hand, the fact that the groups working in the field come from various different physics backgrounds—the authors of this editorial are a representative sample—has been a constant source of inspiration for helpful theoretical and experimental tools that have been adapted from other fields to the mechanical realm. To name just one example: ideas from quantum optics have led to the recent demonstration (both in theory and experiment) that coupling a mechanical resonator to a high-finesse optical cavity can be fully analogous to the well-known sideband-resolved laser cooling of ions and hence is capable in principle of cooling a mechanical mode into its quantum ground state. There is no doubt that such interdisciplinarity has been a crucial element for the development of the field. It is interesting to note that a very similar sociological phenomenon occurred earlier in the quantum information community, an area which is deeply enriched by the

    -based light sources. However, the progress in the last few years in LED and OLED sources has been even greater. In the editorial for the LS-11 conference by previous guest editor David Wharmby, it was stated that most LED lighting was still mostly used for signalling and decorative sources. In the three years that have passed, things have changed considerably and we now see LED light sources entering every application, ranging from street lighting and parking lots to shop lighting and even greenhouses. Currently LED prices for traditional lighting applications are high, but they are dropping rapidly. The papers published in this special issue give some indications of things to come. The paper by Jamil et al deals with the possibility of using silicon wafers as substrate material instead of the now commonly used (but more expensive) sapphire substrates. This is attractive from a cost price point of view, but leads to an increased lattice mismatch and therefore strain-induced defects. In this paper it is shown that when using intermediate matching layers it is possible to retain the same electrical and optical properties as with structures on sapphire. Another aspect that directly relates to cost is efficiency and droop in green InGaN devices, which is addressed in the paper by Lee et al. They show that by providing a flow of trymethylindium prior to the growth of the quantum wells it is possible to significantly increase the internal quantum efficiency of green LEDs. Improvement of the optical out-coupling of InGaN LEDs is discussed by Mak et al, and it is found that localized plasmon resonance of metallic nanoparticles (and especially silver) can help to increase the optical out-coupling in the wavelength region of interest. Nanoparticles in the form of ZnO nanorods are described by Willander et al as a possibility for phosphor-free wavelength conversion on polymer (O)LEDs. More advanced functions besides light emission can be achieved with OLEDs and this is demonstrated in

    Background Latinas with breast cancer suffer symptom and psychosocial health disparities. Effective interventions have not been developed for or tested in this population. Purpose We describe community-based participatory research methods used to develop and implement the Nuevo Amanecer program, a culturally tailored, peer-delivered cognitive-behavioral stress management intervention for low-income Spanish-speaking Latinas with breast cancer, and unique considerations in implementing a randomized controlled trial to test the program in community settings. Methods We applied an implementation science framework to delineate the methodological phases used to develop and implement the Nuevo Amanecer program and trial, emphasizing community engagement processes. Results In phase 1, we established project infrastructure: academic and community Co-Principal Investigators, community partners, community advisory board, steering committee, and funding. In phase 2, we identified three program inputs: formative research, a community best practices model, and an evidence-based intervention tested in non-Latinas. In phase 3, we created the new program by integrating and adapting intervention components from the three sources, making adaptations to accommodate low-literacy, Spanish language, cultural factors, community context, and population needs. In phase 4, we built community capacity for the program and trial by training field staff (recruiters and interventionists embedded in community sites), compensating field staff, and creating a system for identifying potential participants. In phase 5, we implemented and monitored the program and trial. Engaging community partners in all phases has resulted in a new, culturally tailored program that is suitable for newly diagnosed Latinas with breast cancer and a trial that is acceptable and supported by community and clinical partners. Lessons Learned Engagement of community-based organizations and cancer survivors as research

    Largemouth bass, Micropterus salmoides, is a native fish species with special importance for sport fishing competitions in Nuevo León, Mexico. However, no study has investigated the parasitic fauna of M. salmoides, and no reports are available on monogenean parasites in this fish species. Therefore, we described the monogenean parasites of M. salmoides and the effects of season and fish condition factor in five reservoirs: La Boca (LB), El Cuchillo-Solidaridad (CS), Sombreretillo (S), Laguna Salinillas (LS) and Cerro Prieto (CP). The monogeneans infecting M. salmoides were Clavunculus unguis and Acolpenteron ureteroecetes (collected in all localities), as well as Syncleithrium fusiformis, Haplocleidus furcatus, Clavunculus bifurcatus and Urocleidus principalis (CS). Clavunculus unguis had the highest prevalence in fish from all reservoirs. The abundance of monogeneans was generally greater in late spring to autumn than in winter. Although season was not correlated with abundance (r s = 0.0934, P <  0.0154), the months of highest temperature (from May to September) were positively correlated with parasite abundance. A significant association was observed between fish condition factor and the presence of monogeneans (P <  0.05), except for A. ureteroecetes. Our findings include five new geographic records for C. unguis, S. fusiformis, H. furcatus and C. bifurcatus.

    It is with a great deal of both happiness and sadness that I have to announce that we are losing one of the real strengths of the Journal of Physics: Condensed Matter (JPCM). Dr Richard Palmer, our Senior Publisher, announced his retirement, and this issue marks the first without his involvement. Of course, we are happy that he will get to enjoy his retirement, but we are sad to lose such a valuable member of our team. Richard first started work at IOP Publishing in March 1971 as an Editorial Assistant with Journal of Physics B: Atomic and Molecular Physics. After a few months, he transferred to Journal of Physics C: Solid State Physics. During his first year, he was sent on a residential publishing training course and asked to sign an undertaking to stay at IOP Publishing for at least two years. Although Richard refused to sign, as he did not want to commit himself, he has remained with the journal since then. The following year, the Assistant Editor of Journal of Physics C: Solid State Physics, Malcolm Haines, walked out without notice in order to work on his family vineyard in France, and Richard stepped into the breach. In those days, external editors had a much more hands-on role in IOP Publishing and he had to travel to Harwell to be interviewed by Alan Lidiard, the Honorary Editor of Journal of Physics C: Solid State Physics, before being given the job of Assistant Editor permanently. I am told that in those days the job consisted mainly of editing and proofreading and peer review. There was no journal development work. At some point in the early 1980s, production and peer review were split into separate departments and Richard then headed a group of journals consisting of Journal of Physics C: Solid State Physics, Journal of Physics D: Applied Physics and Journal of Physics F: Metal Physics, Semiconductor Science and Technology, Superconductor Science and Technology, Plasma Physics and Controlled Fusion, and later Nanotechnology and Modelling and Simulation

    As I begin my mandate as Editor-in-Chief of Journal of Physics D: Applied Physics, I can look back with great pleasure at many years of service, as a member of the Editorial Board, to this outstanding instrument of scientific dissemination. Having witnessed the exceptional quantitative and qualitative growth of the journal, I must consider this appointment both an honour and a real challenge. The success of the journal is primarily based on three assets: the authors' talent of course, but also the illuminated leadership of my predecessors at the journal helm and the highly competent, dedicated and responsive staff. I would like to praise, in particular, the leadership of my immediate predecessor and good friend, Pallab Battacharya, the pilot of the years of major qualitative growth. Being Pallab's successor makes my new responsibility even more challenging! The IOP personnel is a key asset for the journal: in my rather broad experience in scientific publishing, I have never seen such a combination of professional experience, commitment and willingness to innovate—a traditional strength of JPD. Regrettably, I cannot acknowledge here all the women and men who contributed to the success of the journal; however, I would like to explicitly acknowledge the outstanding work of Sarah Quin over the past decade. In my new duty, I can fortunately count on her successor, Olivia Roche, whose excellent professional and managerial qualities we can already appreciate. How should we view the future of the journal? In my view, with reasonable optimism. Notwithstanding the tough competition, our journal has a solid reputation and increasing visibility. It has consistently belonged to the small elite group of top journals preferred by applied physics authors worldwide. My program as Editor-in-Chief is both simple and very testing: to continue to enhance this elite status. The challenge comes from a variety of factors: first, 'applied physics' is a continuously evolving notion, even

    Background: Establishing a clear treatment paradigm for octogenarians with type II odontoid fractures in hampered by a literature replete with level III articles. Methods: In the study by Graffeo et al., the authors evaluated 111 patients over the age of 79 (average age: 87) with type II odontoid fractures undergoing nonoperative (94 patients) vs. operative intervention (17 total; 15 posterior and 2 anterior). They studied multiple variables and utilized several scales [abbreviated injury scale (AIS), injury severity score (ISS), and the Glasgow coma scale (GCS)] to determine the outcomes of nonoperative vs. operative management. Results: Graffeo et al. concluded that there were no significant differences between nonoperative and operative management for type II odontoid fractures in octogenarians. They found similar frequencies of additional cervical fractures, mechanisms of injury, GCS of 8 or under, AIS/ISS scores, and disposition to “nonhome” facilities. Furthermore, both appeared to have increased mortality rates at 1-year post injury; 13% during hospitalization, 26% within the first post-injury month, and 41% at 1 year. Conclusions: In the editorial by Falavigna, his major criticism of Graffeo's article was the marked disparity in the number of patients in the operative (17 patients) vs. the nonoperative group (94 patients), making it difficult to accept any conclusions as “significant”. He further noted that few prior studies provided level I evidence, and that most, like this one, were level III analyses that did not “significantly” advance our knowledge as to whether to treat octogenarians with type II odontoid fractures operatively vs. nonoperatively.

    Children are at increased vulnerability to many environmental contaminants compared to adults due to their unique behavior patterns, increased contaminant intake per body weight, and developing biological systems. Depending upon their age, young children may crawl on the floor and may practice increased hand to mouth activity that may increase their dose-intake of specific contaminants that accumulate in dust and other matrices. Children are also smaller in size than adults, resulting in a greater body burden for a given contaminant dose. Because children undergo rapid transitions through particular developmental stages they are also especially vulnerable during certain growth-related time windows. A Special Issue was organized focused on the latest findings in the field of children’s environmental exposure for these reasons. This editorial introduces articles in this Special Issue and emphasizes their main findings in advancing the field. From the many articles submitted to this Special Issue from around the world, 23 were accepted and published. They focus on a variety of research areas such as children’s activity patterns, improved risk assessment methods to estimate exposures, and exposures in various contexts and to various contaminants. The future health of a nation relies on protecting the children from adverse exposures and understanding the etiology of childhood diseases. The field of children’s environmental exposures must consider improved and comprehensive research methods aimed at introducing mitigation strategies locally, nationally, and globally. We are happy to introduce a Special Issue focused on children’s environmental exposure and children’s health and hope that it contributes towards improved health of children. PMID:27834888

    El Senado Academico del Recinto de Rio Piedras de la Universidad de Puerto Rico aprobo en el ano academico 2005-2006 la Certificacion 46, que contiene los lineamientos de un nuevo bachillerato. Este nuevo bachillerato introdujo cambios significativos en el curriculo tradicional. Entre ellos se encuentra la reduccion del componente de educacion general y el de Ciencias Biologicas en particular. La reduccion de creditos en el componente de Ciencias Biologicas ha obligado a reevaluar el concepto de cultura cientifica que desarrollan esos cursos. El proposito del estudio consistio en auscultar las percepciones de los profesores de las Facultades de Administracion de Empresas, Humanidades, Ciencias Sociales, Ciencias Naturales, Educacion y Estudios Generales del Recinto de Rio Piedras de la Universidad de Puerto Rico en torno al concepto de cultura cientifica, los contenidos disciplinares del curso de Ciencias Biologicas y la reduccion de creditos en el nuevo bachillerato. Las preguntas que guiaron la investigacion fueron: ¿cuales son las percepciones que tienen los profesores de las Facultades de Administracion de Empresas, Ciencias Sociales, Estudios Generales, Ciencias Naturales, Humanidades y Educacion, en torno al concepto de cultura cientifica y los contenidos disciplinares del curso de Ciencias Biologicas? ¿cuales son las percepciones que tienen los profesores de Ciencias Biologicas en torno al concepto cultura cientifica y los contenidos disciplinares del curso de Ciencias Biologicas? ¿existen diferencias significativas por facultad, genero, experiencia, rango y nombramiento en las percepciones que tienen los profesores del Recinto de Rio Piedras de la Universidad de Puerto Rico sobre los elementos que caracterizan la cultura cientifica y los contenidos biologicos que deben tener los egresados del Recinto? ¿que implicaciones curriculares tienen estos testimonios en el desarrollo del concepto de cultura cientifica en el nuevo bachillerato?

    This is an editorial overview of the Siberia Integrated Regional Study (SIRS), which is a large-scale investigation of ongoing and future environmental change in Siberia and its relationship to global processes, approaches, existing challenges and future direction. Introduction The SIRS is a mega-project within the Northern Eurasia Earth Science Partnership Initiative (NEESPI), which coordinates interdisciplinary, national and international activities in Northern Eurasia that follow the Earth System Science Program (ESSP) approach. Under the direction of the International Geosphere-Biosphere Program (IGBP), SIRS is one of the Integrated Regional Studies (IRS) that aims to investigate environmental change in Siberia under the current environment of global change, and the potential impact on Earth system dynamics [1]. The regions of interest are those that may function as 'choke or switch points' for the global Earth system, where changes in regional biophysical, biogeochemical and anthropogenic components may have significant consequences for the Earth system at the global scale. Siberia is a large and significant region that may compel change [2]. Regional consequences of global warming (e.g. anomalous increases in cold season temperatures) have already been documented for Siberia [3]. This result is also supported by climate modeling results for the 20th-22nd centuries [4]. Future climatic change threatens Siberia with the shift of permafrost boundaries northward, dramatic changes in land cover (redistribution among boreal forest, wetlands, tundra, and steppe zones often precipitated by fire regime change) and the entire hydrological regime of the territory [5-8]. These processes feed back to and influence climate dynamics through the exchange of energy, water, greenhouse gases and aerosols [9]. Even though there have been a handful of national and international projects focused on the Siberian environment, scientists have minimal knowledge about the processes

    Objectives Lyme disease is a tick-borne disease caused by infections with Borrelia. Persons infected with Borrelia can be asymptomatic or can develop disseminated disease. Diagnosis and recognition of groups at risk of infection with Borrelia burgdorferi is of great interest to contemporary rheumatology. There are a few reports about Borrelia infection in Mexico, including lymphocytoma cases positive to B. burgdorferi sensu stricto by PCR and a patient with acrodermatitis chronica atrophicans. Veterinarians have an occupational risk due to high rates of tick contact. The aim of this work was to investigate antibodies to Borrelia in students at the Faculty of Veterinary Medicine and Zootechnics, at Nuevo León, Mexico, and determine the antibody profile to B. burgdorferi antigens. Material and methods Sera were screened using a C6 ELISA, IgG and IgM ELISA using recombinant proteins from B. burgdorferi, B. garinii and B. afzelii. Sera with positive or grey-zone values were tested by IgG Western blot to B. burgdorferi sensu stricto. Results All volunteers reported tick exposures and 72.5% remembered tick bites. Only nine persons described mild Lyme disease related symptoms, including headaches, paresthesias, myalgias and arthralgias. None of the volunteers reported erythema migrans. Nine samples were confirmed by IgG Western blot. The profile showed 89% reactivity to OspA, 67% to p83, and 45% to BmpA. Conclusions Positive sera samples shared antibody reactivity to the markers of late immune response p83 and BmpA, even if individuals did not present symptoms of Lyme arthritis or post-Lyme disease. The best criterion to diagnose Lyme disease in our country remains to be established, because it is probable that different strains coexist in Mexico. This is the first report of antibodies to B. burgdorferi in Latin American veterinarians. Veterinarians and high-risk people should be alert to take precautionary measures to prevent tick-borne diseases. PMID:27504018

An accurate knowledge of these interior pressures is of considerable value for fundamental studies. Since the gradient of the pressure appears in the Navier-Stokes equations, a knowledge of the pressure at a bounding surface followed by operations on the measured velocity components within the flow field can be analytically related to the pressure at an interior location.

In a clear presentation that describes the problem, the paper concentrates on weakly nonlinear phenomena in the acoustic regime. However, both the concepts and theory developed have wide applicability in other fields within measurement science wherever there is a time-varying nonlinear response. The theory uses two methods to estimate noise. The first is called the background frequency method, and the second is a periodic difference method. Both methods have their advantages, and disadvantages, which the authors highlight in a balanced account. They also spend some effort in validating the two approaches.

    Sensors are specific analog devices that convert a physical quantity, like the temperature or external pressure or concentration of carbon monoxide in a confined atmosphere, into an electrical signal. Considered in this way, every sensor is then a part of the artificial interface, which connects the human world to the world of machines. The other side of the interface is represented by actuators. Most often, after processing the data they are used to convert the out-coming electrical power into counteracting physical action. In the last few years, thanks to inexpensive silicon technology, enormous capability for data processing has been developed and the world of machines has become increasingly invasive. The world of sensors has become increasingly complex too. Applications range from classical measurements of the temperature, vibrations, shocks and acceleration to more recent chemical and bio-sensing technologies. Chemical sensors are used to detect the presence of specific, generally toxic, chemical species. To measure their concentration, one uses some specific property, generally a physical one, like the intensity of infrared absorption bands. Bio-sensors are new, more complex, devices that combine a bio-receptor with a physical transducer. The bio-receptor is a molecule (for instance, an enzyme like glucose oxidase) that can recognize a specific target (glucose molecules in the case of glucose oxidase). The enzyme must be fixed on the transducer and, as a consequence of recognition, the transducer must convert the event into a measurable analytical signal. A common feature of many chemical and bio-sensors is that they require a large surface of interaction with the outside world. For that reason and in order to increase efficiency, either nanoparticles or pores or a combination of both, made from various materials including (but not limited to) porous silicon, are often used as the functional transducer interface. The reviews in this Cluster Issue of Journal of Physics D: Applied Physics describe some recent advances in this field and the very different approaches and/or techniques that can be used for the sensors' implementation. They include the use of molecularly modified metal nanoparticles in or as chemical sensors, especially for high sensitivity hydrogen sensors. Hydrogen sensing can also be achieved by performing galvanic measurements on a thin layer of perovskite oxide covered with platinum. In this case, one mixes an ionic (proton) transport in the oxide with an electronic one in the metal. Another focus is on optical and electrical read-out techniques, like surface-plasmon resonance (SPR), such as for immuno-sensor applications or piezo-electrical and electro-chemical detection. Toward this end, the preparation, structure and application of functional interfacial surfaces are described and discussed. A totally different approach based on the use of Hall effect measurements performed on a granular metal-oxide-semiconductor layer and different experimental solutions is also presented. Finally, optical sensors are addressed through the photonic modulation of surface properties or transmission interferometric absorption sensors. Mixed electrical and optical chemical sensors are also examined.

    At the nanoscale measures can move from a mass-scale analogue calibration to counters of discrete units. The shift redefines the possible levels of control that can be achieved in a system if adequate selectivity can be imposed. As an example as ionic substances pass through nanoscale pores, the quantity of ions is low enough that the pore can contain either negative or positive ions. Yet precise control over this selectivity still raises difficulties. In this issue researchers address the challenge of how to regulate the ionic selectivity of negative and positive charges with the use of an external charge. The approach may be useful for controlling the behaviour, properties and chemical composition of liquids and has possible technical applications for nanofluidic field effect transistors [1]. Selectivity is a critical advantage in the administration of drugs. Nanoparticles functionalized with targeting moieties can allow delivery of anti-cancer drugs to tumour cells, whilst avoiding healthy cells and hence reducing some of the debilitating side effects of cancer treatments [2]. Researchers in Belarus and the US developed a new theranostic approach—combining therapy and diagnosis—to support the evident benefits of cellular selectivity that can be achieved when nanoparticles are applied in medicine [3]. Their process uses nanobubbles of photothermal vapour, referred to as plasmonic nanobubbles, generated by plasmonic excitations in gold nanoparticles conjugated to diagnosis-specific antibodies. The intracellular plasmonic nanobubbles are controlled by laser fluence so that the response can be tuned in individual living cells. Lower fluence allows non-invasive high-sensitive imaging for diagnosis and higher fluence can disrupt the cellular membrane for treatments. The selective response of carbon nanotubes to different gases has leant them to be used within various different types of sensors, as summarized in a review by researchers at the University of California, Riverside [4]. Mangu et al in the US have developed highly sensitive and selective room temperature gas sensors made from composites of multiwalled carbon nanotubes and polymers [5]. They report sensitivities as high as 28% when exposed to 100 ppm of NH3 and 29.8% to 100 ppm of NO2. Nanopore structures are also showing increasing promise for sensing and biophysical characterization applications, in particular DNA [6]. An applied potential drives negatively charged DNA molecules through nanopores in a membrane and gives rise to current blockage pulses that are characteristic of specific analytes. Solid-state nanopore structures hold advantages over biological pores, such as those in α-haemolysin protein, as they are more resilient to experimental conditions, and ideally should also allow control of the nanopore diameter, channel length and surface composition. Asghar and colleagues have now reported a method that enables just that, 'a rapid solid-state nanopore fabrication and controlled pore shrinking process which does provide simultaneous in situ control of surface properties' [7]. In addition, they demonstrate the viability of the approach for single molecule sensor applications using double-stranded DNA. In this issue, researchers in China report on a different approach which allows control over the transport of ionic fluids through nanopore-type structures. They describe the rapid field effect control of electrical conductance in single nanotube nanofluidic transistors [1]. Rather than seeking to control the charge of thenanotube inner surface, Gong and colleagues control polarity switching based on negative and positive ion selectivity using an external charge. 'The polarity of the nanotube can be reversed and tuned by the external field, which could find interesting applications in the field of ion separation and energy conversion', they explain, adding that the system may also find a use as a voltage sensor through the detection of the type of ions across the channel. The aim of achieving selectivity encompasses a huge range of fields in nanotechnology research, from sensing and medicine to nanoelectronics and self-assembly. As our understanding of how nanosystems behave deepens, so too does the hunger to improve our capabilities, allowing greater precision and control in manipulating these systems. Selectivity is far from trivial when shrinking to systems of nanoscale dimensions, but the range of opportunities it brings just keeps on growing.

    Research into slow light began theoretically in 1880 with the paper [1] of H A Lorentz, who is best known for his work on relativity and the speed of light. Experimental work started some 60 years later with the work of S L McCall and E L Hahn [2] who explored non-linear self-induced transparency in ruby. This field of research has burgeoned in the last 10 years, starting with the work of L Vestergaard Hau and coworkers on slow light via electromagnetically induced transparency in a Bose-Einstein condensate [3]. Many groups are now able to slow light down to a few metres per second or even stop the motion of light entirely [4]. Today, slow light - or more often `slow and fast light' - has become its own vibrant field with a strongly increasing number of publications. In broad scope, slow light research can be categorized in terms of the sort of physical mechanism used to slow down the light. One sort of slow light makes use of material dispersion. This dispersion can be the natural dispersion of the ordinary refractive index or can be the frequency dependence of some nonlinear optical process, such as electromagnetically induced transparency, coherent population oscillations, stimulated light scattering, or four-wave mixing processes. The second sort of slow light makes use of the wavelength dependence of artificially structured materials, such as photonic crystals, optical waveguides, and collections of microresonators. Material systems in which slow light has been observed include metal vapours, rare-earth-doped materials, Raman and Brillioun gain media, photonic crystals, microresonators and, more recently, metamaterials. A common feature of all of these schemes is the presence of a sharp single resonance or multiple resonances produced by an atomic transition, a resonance in a photonic structure, or in a nonlinear optical process. Current applications of slow light include a series of attractive topics in optical information processing, such as optical data storage, optical memories, quantum information devices, and optical communication systems in which the use of slow light will allow all-optical processing with less wasted heat. To implement these applications, devices such as buffers, memories, interferometers and switches that utilize slow light need to be developed. Future challenges include the need for improved coupling of light into slow light modes, overcoming propagation losses, and mitigating the influence of large dispersion of the group velocity. The collection of papers in this special issue of Journal of Optics features a broad spectrum of articles that highlight actual developments in many of the material types and schemes described above. It represents therefore an excellent up to date snapshot of the current state of the field of slow light research.

    Control of quantum phenomena has grown from a dream to a burgeoning field encompassing wide-ranging experimental and theoretical activities. Theoretical research in this area primarily concerns identification of the principles for controlling quantum phenomena, the exploration of new experimental applications and the development of associated operational algorithms to guide such experiments. Recent experiments with adaptive feedback control span many applications including selective excitation, wave packet engineering and control in the presence of complex environments. Practical procedures are also being developed to execute real-time feedback control considering the resultant back action on the quantum system.

    Honorary Editor The standard of educational achievement in England and Wales is frequently criticized, and it seems to be an axiom of government that schools and teachers need to be shaken up, kept on a tight rein, copiously inspected, shamed and blamed as required: in general, subjected to the good old approach of: ' Find out what Johnny is doing and tell him to stop.' About the only exception to this somewhat severe attitude is at A-level, where the standard is simply golden. Often, comparisons are made between the performance of, say, English children and that of their coevals in other countries, with different customs, systems, aims and languages. But there has been a recent comparison of standards at A-level with a non-A-level system of pre-university education, in an English-speaking country that both sends students to English universities and accepts theirs into its own, and is, indeed, represented in the UK government at well above the level expected from its ethnical weighting in the population. This semi-foreign country is Scotland. The conclusions of the study are interesting. Scotland has had its own educational system, with `traditional breadth', and managed to escape much of the centralized authoritarianism that we have been through south of the border. It is interesting to note that, while for the past dozen years or so the trend in A-level Physics entries has been downwards, there has been an increase in the take-up of Scottish `Highers'. Highers is a one-year course. Is its popularity due to its being easier than A-level? Scottish students keen enough to do more can move on to the Certificate of Sixth Year Studies, and will shortly be able to upgrade a Higher Level into an Advanced Higher Level. A comparability study [ Comparability Study of Scottish Qualifications and GCE Advanced Levels: Report on Physics January 1998 (free from SQA)] was carried out by the Scottish Qualifications Authority (SQA) with the aim (amongst others) of helping universities make a fair comparison between grades attained in A-Levels and Highers, CSYS and Advanced Highers. It was a fairly limited exercise, but a careful one, carried out by examiners and teachers rather than statisticians. They compared syllabuses, questions and candidates' answers. I quote: '... the two years of study for A-level perhaps means that there is a secure, consolidated grasp of the basics; more than the Higher candidate after one year. But there is no evidence of this from candidates' scripts.' Comparing syllabuses, the report noted a greater mathematical demand in Scotland: 'The rigour or depth of treatment is generally lower in the Syllabus Y [an A-level syllabus.] than in CSYS or Advanced Higher because many topics have a qualitative treatment rather than the mathematical treatment of CSYS and AH.' Adding a certain sting to its tail, the report concludes: `Many of the CSYS candidates will have achieved excellent grades at Higher... in four or five subjects before proceeding to CSYS. Scottish candidates tend to have qualifications in a broader range of subjects.' Perhaps this is why they get to be in charge everywhere.

    All matter is more or less hygroscopic. The moisture content varies with vapour concentration of the surrounding air and, as a consequence, most material properties change with humidity. Mechanical and thermal properties of many materials, such as the tensile strength of adhesives, stiffness of plastics, stoutness of building and packaging materials or the thermal resistivity of isolation materials, all decrease with increasing environmental humidity or cyclic humidity changes. The presence of water vapour may have a detrimental influence on many electrical constructions and systems exposed to humid air, from high-power systems to microcircuits. Water vapour penetrates through coatings, cable insulations and integrated-circuit packages, exerting a fatal influence on the performance of the enclosed systems. For these and many other applications, knowledge of the relationship between moisture content or humidity and material properties or system behaviour is indispensable. This requires hygrometers for process control or test and calibration chambers with high accuracy in the appropriate temperature and humidity range. Humidity measurement methods can roughly be categorized into four groups: water vapour removal (the mass before and after removal is measured); saturation (the air is brought to saturation and the `effort' to reach that state is measured); humidity-dependent parameters (measurement of properties of humid air with a known relation between a specific property and the vapour content, for instance the refractive index, electromagnetic spectrum and acoustic velocity); and absorption (based on the known relation between characteristic properties of non-hydrophobic materials and the amount of absorbed water from the gas to which these materials are exposed). The many basic principles to measure air humidity are described in, for instance, the extensive compilations by Wexler [1] and Sonntag [2]. Absorption-type hygrometers have small dimensions and can be produced at relatively low cost. Therefore, they find wide use in lots of applications. However, the method requires a material that possesses some conflicting properties: stable and reproducible relations between air humidity, moisture uptake and a specific property (for instance the length of a hair, the electrical impedance of the material), fast absorption and desorption of the water vapour (to obtain a short response time), small hysteresis, wide range of relative humidity (RH) and temperature-independent output (only responsive to RH). For these reasons, much research is done and is still going on to find suitable materials that combine high performance and low price. In this special feature, three of the four papers report on absorption sensors, all with different focus. Aziz et al describe experiments with newly developed materials. The surface structure is extensively studied, in view of its ability to rapidly absorb water vapour and exhibit a reproducible change in the resistance and capacitance of the device. Sanchez et al employ optical fibres coated with a thin moisture-absorbing layer as a sensitive humidity sensor. They have studied various coating materials and investigated the possibility of using changes in optical properties of the fibre (here the lossy mode resonance) due to a change in humidity of the surrounding air. The third paper, by Weremczuk et al, focuses on a cheap fabrication method for absorption-based humidity sensors. The inkjet technology appears to be suitable for mass fabrication of such sensors, which is demonstrated by extensive measurements of the electrical properties (resistance and capacitance) of the absorbing layers. Moreover, they have developed a model that describes the relation between humidity and the electrical parameters of the moisture-sensitive layer. Despite intensive research, absorption sensors still do not meet the requirements for high accuracy applications. The dew-point temperature method is more appropriate, since it uses the accurately known relation between temperature and saturation vapour pressure in air. When an object exposed to humid air is cooled down below the dew-point water vapour condenses as drops on its cold surface. The temperature can be kept exactly at the dew point by controlling the amount of dew (equilibrium between evaporation and condensation). In most dew-point hygrometers dew is detected with optical or capacitive means. In the former the dew drops on a reflective surface (chilled mirror) scatter incident light, and the capacitive method uses the change in capacitance due to the large dielectric constant of liquid water (80) compared to air (1). Kunze et al, in the fourth paper of this special feature, use another property of water to detect dew: the relatively high value of the thermal capacitance of liquid water. In traditional technology this method would not be sensitive enough, but with MEMS technology a sufficient detectivity of dew can be achieved, which is demonstrated in this paper. A control system keeps the temperature of the substrate just at the dew-point temperature, the latter being measured by an on-chip diode. The accuracy achieved is comparable with traditional dew-point hygrometers. These four papers in this issue are nice examples of research leading to significant advances in hygrometry.

    The first observations of the photoelectric effect date back to the early 19th century from work by Alexandre Edmond Becquerel, Heinrich Hertz, Wilhelm Hallwachs and J J Thomson. The theory behind the phenomena was clarified in a seminal paper by Einstein in 1905 and became an archetypical feature of the wave-particle description of light. A different manifestation of quantised electron excitation, whereby electrons are not emitted but excited into the valence band of the material, is what we call the photoconductive effect. As well as providing an extension to theories in fundamental physics, the phenomenon has spawned a field with enormous ramifications in the energy industry through the development of solar cells. Among advances in photovoltaic technology has been the development of organic photovoltaic technology. These devices have many benefits over their inorganic counterparts, such as light-weight, flexible material properties, as well as versatile materials' synthesis and low-cost large-scale production—all highly advantageous for manufacturing. The first organic photovoltaic systems were reported over 50 years ago [1], but the potential of the field has escalated in recent years in terms of efficiency, largely through band offsetting. Since then, great progress has been made in studies for optimising the efficiency of organic solar cells, such as the work by researchers in Germany and the Netherlands, where investigations were made into the percentage composition and annealing effects on composites of poly(3-hexylthiophene) (P3HT) and the fullerene derivative [6,6]-phenyl-C61 butyric acid methyl ester (PCBM) [2]. Hybrid devices that aim to exploit the advantages of both inorganic and organic constituents have also proven promising. One example of this is the work reported by researchers in Tunisia and France on a systematic study for optimising the composition morphology of TiO2 nanoparticles in poly(N-vinylcarbazole) (PVK), which also led to insights into the charge transport mechanism and trap distribution in these composites [3]. An advantage of investigating solar cell technology based on organic materials rather than silicon is that silicon photovoltaics requires high-purity silicon, whereas the material demands of organic technology are not nearly so strict. Work by researchers in Denmark and Germany highlights the simplicity and tolerance to ambient conditions of organic photovoltaic fabrication in the demonstration of a nanostructured polymer solar cell made from a thermocleavable polymer material and zinc oxide nanoparticles. All the manipulations during device preparation could be carried out in air at around 20 °C and 35% humidity [4]. A possible route to enhancing cell performance is through the improvment of the transport efficiency. Researchers in Taiwan demonstrate how effectively this can be implemented in a hybrid device comprising TiO2 nanorods and poly[2-methoxy-5-(2-ethyl-hexyloxy)-1,4-phenylene vinylene] (MEH-PPV) [5]. In addition, inorganic semiconductor nanocrystals that have tunable optical bandgaps can be combined with organic semiconductors for the fabrication of hybrid photovoltaic devices with broad spectral sensitivity. A collaboration of researchers in the UK and the US has now developed a near-infrared sensitive hybrid photovoltaic system with PbS nanocrystals and C60. The reported improvement in device performance is attributed to increased carrier mobility of the PbS nanocrystal film [6]. In this issue, Patrick G Nicholson and Fernando A Castro from the National Physical Laboratory in the UK present a topical review on the principles and techniques for the characterization of organic photovoltaics [7]. The review presents a comprehensive picture of the current state-of-the-art understanding of the working mechanisms behind organic solar cells, and also describes electronic morphological considerations relevant to optimizing the devices, as well as different nanoscale techniques for investigating organic solar cell technology. In spring 2011, Nanotechnology launches a new section wholly dedicated to the coverage of new and stimulating research into energy sources based on nanoscale science and technology. There is at present considerable concern over how to fuel the planet in a sustainable manner with the increasingly energy-thirsty human population. Yet the Earth receives more solar energy in one hour than the world population consumes in one year [8]. No wonder research into photovoltaics and ways of increasing the efficiency with which this energy can be harnessed continues to hold so much fascination. References [1] Levin I and White C E 1949 J.

    Boris Petrovitch Zakharchenya (1928-2005) This issue is dedicated to the memory of Boris Petrovich Zakharchenya, who died at the age of 77 in April 2005. He was an eminent scientist and a remarkable man. After studying physics at Leningrad University he joined the Physico-Technical Institute (now the A F Ioffe Institute) in 1952 and became the co-worker of Evgeny Feodorovich Gross, shortly after the exciton was discovered in his laboratory. The experiments on cuprous oxide crystals in the visible spectral range showed a hydrogen-like spectrum, which was interpreted as excitonic absorption. The concept of the exciton had been conceived some years earlier by Jacov Frenkel at the Physico-Technical Institute. Immediately after joining Gross, Zakharchenya succeeded in producing spectra of unprecedented quality. Subsequently the heavy and the light hole series were found. Also, Landau splitting was discovered when a magnetic field was applied. The interpretation of the discovery was thrown into doubt by Russian colleagues and it took some time, before the correct interpretation prevailed. Shortly before his death, Boris wrote the history of the discovery of the exciton, which has recently been published in Russian in a book celebrating the 80th anniversary of his birth [1]. The book also contains essays by Boris on various themes, not only on physics, but also on literature. Boris was a man of unusually wide interests, he was not only fascinated by physics, but also loved literature, art and music. This can be seen in the first article of this issue The Play of Light in Crystals which is an abbreviated version of his more complete history of the discovery of the exciton. It also gives a good impression of the personality of Boris. One of us (GL) had the privilege to become closely acquainted with him, while he was a guest professor at the University of Würzburg. During that time we had many discussions, and I recall his continuing rage on the wrong attribution of the priority of the discovery in the literature, which was partly caused by the existence of the Iron Curtain. I had already enjoyed contact with Boris in the 1980s when the two volumes of Landau Level Spectroscopy were being prepared [2]. He was one of the pioneers of magneto-optics in semiconductors. In the 1950s the band structure of germanium and silicon was investigated by magneto-optical methods, mainly in the United States. No excitonic effects were observed and the band structure parameters were determined without taking account of excitons. However, working with cuprous oxide, which is a direct semiconductor with a relative large energy gap, Zakharchenya and his co-worker Seysan showed that in order to obtain correct band structure parameters, it is necessary to take excitons into account [3]. About 1970 Boris started work on optical orientation. Early work by Hanle in Germany in the 1920s on the depolarization of luminescence in mercury vapour by a transverse magnetic field was not appreciated for a long time. Only in the late 1940s did Kastler and co-workers in Paris begin a systematic study of optical pumping, which led to the award of a Nobel prize. The ideas of optical pumping were first applied by Georges Lampel to solid state physics in 1968. He demonstrated optical orientation of free carriers in silicon. The detection method was nuclear magnetic resonance; optically oriented free electrons dynamically polarized the 29Si nuclei of the host lattice. The first optical detection of spin orientation was demonstrated by with the III-V semiconductor GaSb by Parsons. Due to the various interaction mechanisms of spins with their environment, the effects occurring in semiconductors are naturally more complex than those in atoms. Optical detection is now the preferred method to detect spin alignment in semiconductors. The orientation of spins in crystals pumped with circularly polarized light is deduced from the degree of circular polarization of the recombination radiation. The major results of the systematic work on optical orientation, both experimental and theoretical, at the Ioffe Institute and the Ecole Normale Supérieure in Paris are documented in the book Optical Orientation, edited by F Meier and B P Zakharchenya in the series Modern Problems in Condensed Matter Sciences [4], in which the foundations of optical orientation are comprehensively presented by renowned authors. This book is still the unsurpassed standard work in the field. If one asks what has become new since that publication in 1984 it is obviously the arrival of low-dimensional structures, two-dimensional heterostructures and zero-dimensional quantum dots. It has turned out that the quantum confinement can significantly modify the spin lifetime and the spin relaxation. The experimental work on spin alignment was done by a relative small number of researchers. However, the situation has substantially changed during the last decade. Research on spin-related phenomena has become very popular and the word 'spintronics' was coined. Spin research is no longer considered to be somewhat esoteric, since the replacement of silicon microelectronics based on the electron charge by spin-based electronics is being discussed. Whether these proposals can be realized remains to be seen. But one consequence has been a worldwide increase of high level basic research in spin phenomena. Another line of current research which has contributed to the popularity of spin-related research is quantum computing, based on spin-qubits. To be useful, solid state systems require long spin relaxation times and weak interaction with the environment. This is indispensable for low error rates. The difficulties in achieving these goals have been extensively discussed in the literature. Nowadays, because of the volume and diversity of spin-related work worldwide, a book on optical orientation like that edited by Meyer and Zakharchenya does not seem possible, so in this special issue of Semiconductor Science and Technology we try, with examples, to give an impression of that current state of research. The articles will not be discussed individually but their titles reveal that most deal with low-dimensional systems. The study of spin relaxation plays a major role. Interface effects at the ferromagnet/semiconductor boundary are subtle and important for spin injection from a ferromagnet. Each of the contributions is a combination of review and recent results and stands by itself. The affiliations of the authors reveal that the majority come from St Petersburg, clearly indicating that the heritage of Boris Zakharchenya is alive and thriving. We would like to thank all authors for their cooperation, especially for delivering their manuscripts in a reasonable time. Claire Bedrock and Adam Day of the IOP Publishing deserve thanks for their support in the publication process. We are much indebted to Ruslana Zakharchenya for making the manuscript on the discovery of the exciton available and especially to Nina Nikolaevna Vasil'eva for her translation.

    Feature Issue Editor The World Wide Web has been described as a `distributed heterogeneous collaborative multimedia information system'. It began as a networked information project at CERN, where Tim Berners-Lee, now Director of the World Wide Web Consortium [W3C], developed a vision of the project. The Web has a body of software and a set of protocols and conventions. Through the use of hypertext and multimedia techniques, the Web is easy for anyone to roam, browse and contribute to. It was developed by physicists at CERN to fulfil a communication need, and is one of the fastest growing resources worldwide. The number of available sites increases hourly, the ability to find information becomes easier, and contacting anyone with an e-mail address is as easy as picking up the telephone and talking to them. A pupil researching a project on say `alternative energy' simply launches a web browser with the relevant search criteria. Some 13 500 references later they cut and paste sections together and, hey presto, they have their article. The teacher, on the other hand, has to discern what input to this work the pupil has made! What credit should be given for such an attempt? I believe we are going to have to teach how to value a site, by comparing it with other similar sites and exercising some judgement on what we find. Using a search with `physics' as my only keyword found more than 3.5 million references! Clearly the researcher has to become discerning, being judge and jury as it were. Will the Internet catch on? I fear so, is the simple answer. However, I am concerned that with so much information available the ability to discern quality sites from inferior ones and fact from fiction will become a major issue for educationalists. Pupils are going to have to be taught how to assess a site, how to judge its validity and learn to give correct references in their reports. Because Internet sites are ephemeral, a reference given today may not be active next week. Indeed, it is true for this edition of Physics Education: all the sites given were checked before publication. However, we cannot be held responsible for non-availability of a site, should the service provider decide to remove or archive that particular page. Any user surfing the net must be prepared for the message File Not Found. The requested URL was not found on this server. Why is looking for information on the Internet referred to as surfing? It has been suggested that you are looking for the ultimate wave/site - the one that answers your questions or gives you that special information. It is certainly addictive, and when a good site is found it is very rewarding. I find the analogy with surfing particularly accurate, as most of my time is spent in the water splashing around! When you do get on the board, the thought of jumping from country to country as you click on each hypertext link is quite exhilarating. The wealth of information you have access to is awesome, defying comprehension. Finding a good book, article, reference or person to help you, makes it more than justify its existence. Looking for fellow teachers of physics could not be easier. PEERS (Physics Encyclopaedia of E-mail Records), the database of physicists maintained by IOP, should be a wonderful resource for teachers, industrialists or anyone linked with physics. I decided to find out how many schools had registered themselves with PEERS. I constructed a search of Type of Institution: School and found 113 records, but then refined my search to Country: UK and Subject: Physics and was amazed to find only 23 records. Rest of the world 90, UK 23! I suggest the moment you put this journal down you go and register with PEERS (http://www.iop.org/cgi-bin/PEERS/main); it is FREE! At a recent IOP update course in Oxford, I was pleased to see most lecturers using laptops linked to video projectors to give their presentations, and references were made to sources of information on the WWW. With the availability of lecture notes, worksheets, examination courses, databases and virtual libraries all on the Internet, a new breed of education is being spawned. If previous generations have remembered the coming of the motor car, flight and the steam engine, clearly the 1990s must be attributed to the World Wide Web. So, what of the future? Clearly the Internet is not going to go away, and we as educators are going to have to tame the beast. I hope books will still be valued and often ask myself how we teach such appreciation. With the availability of complete Sc1's on the Internet, or essays for the Nuffield Research & Analysis ready for downloading, our present examination structure will need some rethinking .... ... and finally: We are all very busy people; if you have spent two hours finding a good site, please let us know, so we may publish it in a future issue. We are very bad at communicating/sharing our ideas, and the WWW has given us the perfect tool - let us use IT! Good physics sites to: ped@ioppublishing.co.uk Happy surfing!

    Investigations of light-matter interactions and motion in the microcosm have entered a new temporal regime, the regime of attosecond physics. It is a main 'spin-off' of strong field (i.e., intense laser) physics, in which nonperturbative effects are fundamental. Attosecond pulses open up new avenues for time-domain studies of multi-electron dynamics in atoms, molecules, plasmas, and solids on their natural, quantum mechanical time scale and at dimensions shorter than molecular and even atomic scales. These capabilities promise a revolution in our microscopic knowledge and understanding of matter. The recent development of intense, phase-stabilized femtosecond (10-15 s) lasers has allowed unparalleled temporal control of electrons from ionizing atoms, permitting for the first time the generation and measurement of isolated light pulses as well as trains of pulses on the attosecond (1 as = 10-18 s) time scale, the natural time scale of the electron itself (e.g., the orbital period of an electron in the ground state of the H atom is 152 as). This development is facilitating (and even catalyzing) a new class of ultrashort time domain studies in photobiology, photochemistry, and photophysics. These new coherent, sub-fs pulses carried at frequencies in the extreme ultraviolet and soft-x-ray spectral regions, along with their intense, synchronized near-infrared driver waveforms and novel metrology based on sub-fs control of electron-light interactions, are spawning the new science of attosecond physics, whose aims are to monitor, to visualize, and, ultimately, to control electrons on their own time and spatial scales, i.e., the attosecond time scale and the sub-nanometre (Ångstrom) spatial scale typical of atoms and molecules. Additional goals for experiment are to advance the enabling technologies for producing attosecond pulses at higher intensities and shorter durations. According to theoretical predictions, novel methods for intense attosecond pulse generation may in future involve using overdense plasmas. Electronic processes on sub-atomic spatio-temporal scales are the basis of chemical physics, atomic, molecular, and optical physics, materials science, and even some life science processes. Research in these areas using the new attosecond tools will advance together with the ability to control electrons themselves. Indeed, we expect that developments will advance in a way that is similar to advances that have occurred on the femtosecond time scale, in which much previous experimental and theoretical work on the interaction of coherent light sources has led to the development of means for 'coherent control' of nuclear motion in molecules. This focus issue of New Journal of Physics is centered on experimental and theoretical advances in the development of new methodologies and tools for electron control on the attosecond time scale. Topics such as the efficient generation of harmonics; the generation of attosecond pulses, including those having only a few cycles and those produced from overdense plasmas; the description of various nonlinear, nonperturbative laser-matter interactions, including many-electron effects and few-cycle pulse effects; the analysis of ultrashort propagation effects in atomic and molecular media; and the development of inversion methods for electron tomography, as well as many other topics, are addressed in the current focus issue dedicated to the new field of 'Attosecond Physics'.

    2013-05-01

    A useful synergy is being established between terahertz research and nanotechnology. High power sources [1-3] and detectors [4] in what was once considered the terahertz 'frequency gap' [5] in the electromagnetic spectrum have stimulated research with huge potential benefits in a range of industries including food, medicine and security, as well as fundamental physics and astrophysics. This special section, with guest editors Masayoshi Tonouchi and John Reno, gives a glimpse of the new horizons nanotechnology is broaching in terahertz research. While the wavelengths relevant to the terahertz domain range from hundreds of micrometres to millimetres, structures at the nanoscale reveal interesting low energy dynamics in this region. As a result terahertz spectroscopy techniques are becoming increasingly important in nanomaterial characterization, as demonstrated in this special section by colleagues at the University of Oxford in the UK and the Australian National University. They use terahertz spectroscopy to identify the best nanostructure parameters for specific applications [6]. The low energy dynamics in nanostructures also makes them valuable tools for terahertz detection [7]. In addition the much sought after terahertz detection over broadband frequency ranges has been demonstrated, providing versatility that has been greatly in demand, particularly in spectroscopy applications [8, 9]. Also in this special section, researchers in Germany and China tackle some of the coupling issues in terahertz time domain spectroscopy with an emitter specifically well suited for systems operated with an amplified fibre [3]. 'In medical imaging, the advantage of THz radiation is safety, because its energy is much lower than the ionization energy of biological molecules, in contrast to hazardous x-ray radiation,' explains Joo-Hiuk Son from the University of Seoul in Korea in his review [10]. As he also points out, the rotational and vibrational energies of water molecules are within the THz spectral region providing an additional benefit. His review describes the principle, characteristics, and applications of terahertz molecular imaging, where the use of nanoparticle probes allows dramatically enhanced sensitivity. Jiaguang Han and Weili Zhang and colleagues in China, Saudi Arabia, Japan and the US report exciting developments for optoelectronics [11]. They describe work on plasmon-induced transparency (PIT), an analogue of electromagnetically induced transparency (EIT) where interference leads to a sharp transparency window that may be useful for nonlinear and slow-light devices, optical switching, pulse delay, and storage for optical information processing. While PIT has advantages over the cumbersome experimental systems required for EIT, it has so far been constrained to very narrow band operation. Now Zhang and colleagues present the simulation, implementation, and measurement of a broadband PIT metamaterial functioning across a frequency range greater than 0.40 THz in the terahertz regime. 'We can foresee a historic breakthrough for science and technology through terahertz research,' concluded Masayoshi Tonouchi in his review over five years ago as momentum in the field was mounting [12]. He added, 'It is also noteworthy that THz research is built on many areas of science and the coordination of a range of disciplines is giving birth to a new science.' With the inherently multidisciplinary nature of nanotechnology research it is not so strange to see the marriage of the two fields form such a fruitful partnership, as this special section highlights.

In it he traced the development of JJT's life from his early studies at Owen's College in Manchester, on to Trinity College Cambridge, his work under Rayleigh at the Cavendish, and his succession as Professor of Experimental Physics in 1884 (a post he passed on to Rutherford in 1919). These were years of heroic discoveries that shaped 20th century physics. Looking around the lecture theatre at all the bow-ties and dinner jackets, it must have been rather similar on 30 April 1897 when JJT delivered his famous discourse on 'Cathode Rays' in which he cautiously but confidently announced that his own results together with those of other experimenters (Lenard in particular):

    `....seem to favour the hypothesis that the carriers of the charges are smaller than the atoms of hydrogen.'
    In this issue articles by Leif Gerward and Christopher Cousins, and by Isobel Falconer explore the historical and philosophical context of that discovery. The sound-bites to history in many A-level courses have JJT as both the hero who single-handedly discovered the electron and the rather naive Victorian scientist who thought the atom was a plum pudding. It is valuable to see how Thomson's work pulled the threads of many experiments together and to realize that he may have been first to the post because of a difference in the philosophical approach to cathode rays in Britain compared to Europe. Experimental data must always be interpreted, and divergent philosophies can lead to quite different conclusions. The electron was, of course, the first subatomic particle to be identified. Christine Sutton's article looks at how 20th century discoveries reveal Nature's mysterious habit of repeating successful patterns---electrons for example have very close relations, the muon and the tau---but why? Perhaps the answer will come from the theoreticians. One of the greatest of these was Paul Dirac, a marvellously reticent man with an eye for mathematical beauty. David Miller, one of the winners of William Waldegrave's 'Higgs Challenge' in 1993, shows how Dirac constructed his famous equation, and how it describes the behaviour of the electron and its neutrino and led to the prediction of antimatter and the explanation of spin. He draws an interesting parallel between Dirac's negative energy electrons and the contemporary development of solid state physics. G P Thomson, JJ's son, also got in on the act: father got the Nobel Prize (1906) for showing the electron is a particle and son (1937) won it for showing it also behaves like a wave! This has had a profound impact both on the interpretation and experimental testing of quantum theory and in the way we use electrons. Electron waves are essential to understand solid state physics and wave-like properties are fundamental to the behaviour of many electronic devices. But it is not just in physics and electronics that the electron has been revolutionary, and John Squire's article reviews the use of the electron microscope in biology. Having crossed the border into biology (as so many physicists have done this century) it should be pointed out that electron physics also caused a paradigm shift in chemistry. Electronic structure made the Periodic Table comprehensible and led to a theory of bonding that accounts for the mechanical, electrical and optical properties of many materials. This is described in Peter Hughes's article. Which brings me back to JJT and those sound-bites, and the Royal Institution for that matter.... On 10 March 1905 JJT gave another of his Friday Evening Discourses. This one was called 'The Structure of the Atom'. In it he developed a model suggested by Lord Kelvin, in which negative corpuscles arrange themselves in a stable configuration within a sphere of positively charged fluid. This is the infamous `plum pudding'. There is not room to go into detail here, but he showed mathematically and using a 2D magnetic model that the electrons would arrange themselves in a series of shells which he identified with the periods in the Periodic Table and linked to reactivity. He discussed electronegativity and showed how it would increase along each period (as it does). He suggested transmutation of the elements by a rearrangement of the positive fluid and even considered electrostatic conditions which might result in fission or fusion (remember, this is long before the alpha scattering experiments of Geiger and Marsden). Even covalent and ionic bonding and crystalline structures were included, with atomic valence directions corresponding to lines of symmetry in the electron arrangement inside the atom. It is a shame that the `plum pudding model' gets such shabby treatment, and perhaps a comment on the distorted view of the history of physics we pass on to our students by ignoring the context and background to important discoveries.

    Suddenly, at the end of the last century, classical optics and classical electrodynamics became fashionable again. Fields that several generations of researchers thought were comprehensively covered by the famous Born and Wolf textbook and were essentially dead as research subjects were generating new excitement. In accordance with Richard Feynman’s famous quotation on nano-science, the optical community suddenly discovered that 'there is plenty of room at the bottom'—mixing light with small, meso- and nano-structures could generate new physics and new mind-blowing applications. This renaissance began when the concept of band structure was imported from electronics into the domain of optics and led to the development of what is now a massive research field dedicated to two- and three-dimensional photonic bandgap structures. The field was soon awash with bright new ideas and discoveries that consolidated the birth of the 'new optics'. A revision of some of the basic equations of electrodynamics led to the suspicion that we had overlooked the possibility that the triad of wave vector, electric field and magnetic field, characterizing propagating waves, do not necessarily form a right-handed set. This brought up the astonishing possibilities of sub-wavelength microscopy and telescopy where resolution is not limited by diffraction. The notion of meta-materials, i.e. artificial materials with properties not available in nature, originated in the microwave community but has been widely adopted in the domain of optical research, thanks to rapidly improving nanofabrication capabilities and the development of sub-wavelength scanning imaging techniques. Photonic meta-materials are expected to open a gateway to unprecedented electromagnetic properties and functionality unattainable from naturally occurring materials. The structural units of meta-materials can be tailored in shape and size; their composition and morphology can be artificially tuned, and inclusions can be designed and placed at desired locations to achieve new functionality. Among important developments in the new optics was the discovery that a metal film with arrays of small holes in it could be transparent to light beyond any intuitive expectations and that a properly designed metallic structure could be made completely 'invisible' at certain wavelengths. A strong technological drive towards device miniaturization (or, perhaps we should say 'nanoturization'?) has breathed new life into plasmonics—a field many thought had matured some time ago. Surface plasmon polarition waves have come to be seen as potential broadband information carriers for highly integrated photonic devices with research now concentrating on routing and controlling plasmon-polariton signals. Among other new topics in optical electrodynamics are frequency selective surfaces, optical effects of low-dimensional chirality and electrodynamics of toroidal structures. This Special Issue of Journal of Optics A: Pure and Applied Optics on 'Nanostructured Optical Meta-Materials: Beyond Photonic Bandgap Effects' is a very representative cross-section of research in 'new optics', with papers covering essential issues in meta-materials research, surface plasmons, nanostructured surfaces, sub-wavelength imaging, nanostructured and random laser media and nonlinearities in nanostructured films. As the Guest Editors of this Special Issue, we are deeply grateful to all contributing authors for their efforts and their willingness to share recent results within the framework of what promises to be a landmark collection of papers in the field of 'new optics'. We are especially proud that the authorship includes pioneers and newcomers to this intriguing and fertile field of research.

    The development of scanning probe techniques, such as scanning tunnelling microscopy [1], has often been touted as the catalyst for the surge in activity and progress in nanoscale science and technology. Images of nanoscale structural detail have served as an invaluable investigative resource and continue to fascinate with the fantastical reality of an intricate nether world existing all around us, but hidden from view of the naked eye by a disparity in scale. As is so often the case, the invention of the scanning tunnelling microscope heralded far more than just a useful new apparatus, it demonstrated the scope for exploiting the subtleties of electronic contact. The shrinking of electronic devices has been a driving force for research into molecular electronics, in which an understanding of the nature of electronic contact at junctions is crucial. In response, the number of experimental techniques in molecular electronics has increased rapidly in recent years. Scanning tunnelling microscopes have been used to study electron transfer through molecular films on a conducting substrate, and the need to monitor the contact force of scanning tunnelling electrodes led to the use of atomic force microscopy probes coated in a conducting layer as studied by Cui and colleagues in Arizona [2].
