    Full Text Available Abstract Background Quantitative survey of research articles, as an application of bibliometrics, is an effective tool for grasping overall trends in various medical research fields. This type of survey has been also applied to infectious disease research; however, previous studies were insufficient as they underestimated articles published in non-English or regional journals. Methods Using a combination of Scopus™ and PubMed, the databases of scientific literature, and English and non-English keywords directly linked to infectious disease control, we identified international and regional infectious disease journals. In order to ascertain whether the newly selected journals were appropriate to survey a wide range of research articles, we compared the number of original articles and reviews registered in the selected journals to those in the 'Infectious Disease Category' of the Science Citation Index Expanded™ (SCI Infectious Disease Category during 1998-2006. Subsequently, we applied the newly selected journals to survey the number of original articles and reviews originating from 11 Asian countries during the same period. Results One hundred journals, written in English or 7 non-English languages, were newly selected as infectious disease journals. The journals published 14,156 original articles and reviews of Asian origin and 118,158 throughout the world, more than those registered in the SCI Infectious Disease Category (4,621 of Asian origin and 66,518 of the world in the category. In Asian trend analysis of the 100 journals, Japan had the highest percentage of original articles and reviews in the area, and no noticeable increase in articles was revealed during the study period. China, India and Taiwan had relatively large numbers and a high increase rate of original articles among Asian countries. When adjusting the publication of original articles according to the country population and the gross domestic product (GDP, Singapore and

    For contribution of suggestions for establishing directions and concrete tasks for new industrial technology research and development projects, a survey is conducted about trends of industrial technology development and into research domains where importance will gather in the future, for which development trends are studied such as limiting, providing of intelligence, and advanced composition. In this report, domains expected to become important in the future are investigated. Important subjects are found in the domains of the space limiting (micromachining, atom/molecule manipulation, microanalysis, etc.), the time limiting (super-spacetime processing, quantum device, femtosecond technology, 4-dimensional device, etc.), biomimetics and providing of intelligence (intelligent material, neural network, genetic algorithm, artificial life, sensor fusion, intelligent robot, etc.). In addition to these, 'ultrastructure that learns from organisms,' 'intensive interaction system,' and 'nonlinearity/chaos technology' are proposed as promising fields of development. Since Japan is traditionally strong in hardware technologies relating to micromachining and substance/material processing, good results will be attained when the industrial, governmental, and academic circles exert endeavors.

    Survey research is a unique methodology that can provide insight into individuals' perspectives and experiences and can be collected on a large population-based sample. Specifically, in plastic surgery, survey research can provide patients and providers with accurate and reproducible information to assist with medical decision-making. When using survey methods in research, researchers should develop a conceptual model that explains the relationships of the independent and dependent variables. The items of the survey are of primary importance. Collected data are only useful if they accurately measure the concepts of interest. In addition, administration of the survey must follow basic principles to ensure an adequate response rate and representation of the intended target sample. In this article, the authors review some general concepts important for successful survey research and discuss the many advantages this methodology has for obtaining limitless amounts of valuable information.

    To determine the characteristics and trends of the original articles published in two major American radiology journals, AJR American Journal of Roentgenology (AJR) and Radiology, between 2001 and 2010. This was a retrospective bibliometric analysis that did not involve human subjects and was exempt from institutional review board approval. All 6542 original articles published in AJR and Radiology between 2001 and 2010 were evaluated. The following information was abstracted from each article: radiologic subspecialty, radiologic technique used, type of research, sample size, study design, statistical analysis, study outcome, declared funding, number of authors, affiliation of the first author, and country of the first author. In addition, all the variables examined were presented along with the trend over time. The most common subspecialty of study was abdominal (1219 of 6542, 18.6%), followed by vascular/interventional (804 of 6542, 12.3%). A total of 3744 (57.2%) original articles used magnetic resonance (MR) imaging or computed tomography (CT), 5495 (84.1%) were clinical research articles, 3060 (46.8%) had sample size of more than 50, 4087 (62.5%) were retrospective, 4714 (72.1%) performed statistical analysis, 6225 (95.2%) showed positive study outcome, 4784 (73.1%) were not funded, 3942 (60.3%) had four to seven authors, and 5731 (87.6%) were written by the primary author who was from a department of radiology or radiology-related specialties. The United States published 45.5% (2975 of 6542) of the articles, followed by Japan (n = 525, 8.0%), Germany (n = 485, 7.4%), and South Korea (n = 455, 7.0%). In the time trend analysis, the following variables showed a significantly positive trend: cardiac subspecialty, CT and MR imaging as the radiologic techniques, type of research as other (nonbasic, nonclinical), sample size of more than 50, four to seven as the number of authors, medicine-related department of the first author, and South Korea and Italy as

    Trends of research on carbon based composite materials were surveyed through studying various reports and technical literature and evaluation of the project named above was conducted through holding interviews with researchers. In the survey of research trends for which technical literature perusal was the main tool, it was found that in most technical articles the important task was the enhancement of oxidation resistance, that SiC coating was in use for this purpose, that the technology would meet its limit at 1,600-1,700 degrees C, and that it would turn useless at temperatures beyond 1,800 degrees C. For the evaluation of the project, interviews were held with nine researchers not taking part in the project. The researchers favored the project as far as the popularity of the project and the main implementing body and system were concerned, but they negatively evaluated the project's goal of using such materials at 2,000 degrees C in the atmosphere. This research report comprises four chapters which cover (1) trends of research on C/C (carbon/carbon) composites, (2) a summarized research report on C/C composites, (3) survey of patents associated with C/C composites, and (4) opinions expressed toward the project and the results of evaluation conducted on the same.

    The trends of the ongoing researches on intermetallic compounds are surveyed through interviews and inquiries, in order to evaluate the results of the projects and research and development of the advanced materials for severe environments, and also to survey the research trends. The survey results are pigeonholed into 4 general categories; (1) research trends in the USA, UK and Germany, (2) notable topics of recent progress in intermetallic research and development, (3) evaluation of the projects, and (4) lists of the results of the researches on the Al-Ti and Al-Nb intermetallic compounds. The ongoing projects include those for intermetallic compounds of high specific strength and of high melting point, the former being represented by Al-Ti compounds and the latter by Al-Nb compounds, for aircraft and space development purposes. The projects are evaluated, viewed from materials and purposes/targets pursued by the projects, R and D organizations, and degree of attention the projects are attracting. The intermetallic compounds are extensively studied and attracting attention in various countries, but possibilities of achieving the set targets are rather pessimistic. (NEDO)

    The trends in neutron research are discussed from the viewpoints of development of pulsed neutron sources, the ingenuity of specialization of instrumentation and experimental techniques, and research programs. The latter comprise the large and still expanding requirements of nuclear data for nuclear power technology, the requirements of other fundamental sciences, and the experimental and theoretical developments required for a more fundamental understanding of the subject of neutron and related nuclear reactions itself. The general conclusion is that high energy resolution coupled with high intensity for detecting weak reactions provides the key to further progress, and that (provided financial limitations do not stifle the further development of experimental facilities, particularly neutron sources) the subject of neutron physics still has a long and fruitful future

    2014-11-01

    Computer and Internet use in businesses and homes in the United States has dramatically increased since the early 1980s. In 2011, 76% of households reported having a computer, compared with only 8% in 1984 (File, 2013). A similar increase in Internet use has also been seen, with 72% of households reporting access of the Internet in 2011 compared with 18% in 1997 (File, 2013). This emerging trend in technology has prompted use of electronic surveys in the research community as an alternative to previous telephone and postal surveys. Electronic surveys can offer an efficient, cost-effective method for data collection; however, challenges exist. An awareness of the issues and strategies to optimize data collection using web-based surveys is critical when designing research studies. This column will discuss the different types and advantages and disadvantages of using electronic surveys in nursing research, as well as methods to optimize the quality and quantity of survey responses.

    The efforts of the international fusion community aim at demonstrating the scientific feasibility of thermonuclear fusion energy power plants. Understanding the behavior of burning plasmas, i.e. plasmas with strong self-heating, represents a primary scientific challenge for fusion research and a new science frontier. Although integrated studies will only be possible, in new, dedicated experimental facilities, such as the International Tokamak Experimental Reactor (ITER), present devices can address specific issues in regimes relevant to burning plasmas. Among these are an improvement of plasma performance via a reduction of the energy and particle transport, an optimization of the path to ignition or to sustained burn using additional heating and a control of plasma-wall interaction and energy and particle exhaust. These lectures address recent advances in plasma science and technology that are relevant to the development of fusion energy. Mention will be made of the inertial confinement line of research, but...

    2011-06-01

    Landscape classification is the basis of the researches on landscape structure, process, and function, and also, the prerequisite for landscape evaluation, planning, protection, and management, directly affecting the precision and practicability of landscape research. This paper reviewed the research progress on the landscape classification system, theory, and methodology, and summarized the key problems and deficiencies of current researches. Some major landscape classification systems, e. g. , LANMAP and MUFIC, were introduced and discussed. It was suggested that a qualitative and quantitative comprehensive classification based on the ideology of functional structure shape and on the integral consideration of landscape classification utility, landscape function, landscape structure, physiogeographical factors, and human disturbance intensity should be the major research directions in the future. The integration of mapping, 3S technology, quantitative mathematics modeling, computer artificial intelligence, and professional knowledge to enhance the precision of landscape classification would be the key issues and the development trend in the researches of landscape classification.

    1999-12-01

    The Nucleic Acids Research Group of the Association of Biomolecular Resource Facilities (ABRF) last surveyed DNA synthesis core facilities in April 1995. Because of the introduction of new technologies and dramatic changes in the market, we sought to update survey information and to determine how academic facilities responded to the challenge presented by commercial counterparts. The online survey was opened in January 1999 by notifying members and subscribers to the ABRF electronic discussion group. The survey consisted of five parts: general facility information, oligonucleotide production profile, oligonucleotide charges, synthesis protocols, and trends in DNA synthesis (including individual comments). All submitted data were anonymously coded. Respondents from DNA synthesis facilities were primarily from the academic category and were established between 1984 and 1991. Typically, a facility provides additional services such as DNA sequencing and has upgraded to electronic ordering. There is stability in staffing profiles for these facilities in that the total number of employees is relatively unchanged, the tenure for staff averages 5.9 years, and experience is extensive. On average, academic facilities annually produce approximately 1/16 the number of oligonucleotides produced by the average commercial facilities, but all facilities report an increase in demand. Charges for standard oligonucleotides from academic facilities are relatively higher than from commercial companies; however, the opposite is true for modified phosphoramidites. Subsidized facilities charge less than nonsubsidized facilities. Synthesis protocols and reagents are standard across the categories. Most facilities offer typical modifications such as biotinylation. Despite the competition by large commercial facilities that have reduced costs dramatically, academic facilities remain a stable entity. Academic facilities enhance the quality of service by focusing on nonstandard

    Fujisaki, Ikuko; Mazzotti, Frank J.; Dorazio, Robert M.; Rice, Kenneth G.; Cherkiss, Michael; Jeffery, Brian

    2011-01-01

    Nightlight surveys are commonly used to evaluate status and trends of crocodilian populations, but imperfect detection caused by survey- and location-specific factors makes it difficult to draw population inferences accurately from uncorrected data. We used a two-stage hierarchical model comprising population abundance and detection probability to examine recent abundance trends of American alligators (Alligator mississippiensis) in subareas of Everglades wetlands in Florida using nightlight survey data. During 2001–2008, there were declining trends in abundance of small and/or medium sized animals in a majority of subareas, whereas abundance of large sized animals had either demonstrated an increased or unclear trend. For small and large sized class animals, estimated detection probability declined as water depth increased. Detection probability of small animals was much lower than for larger size classes. The declining trend of smaller alligators may reflect a natural population response to the fluctuating environment of Everglades wetlands under modified hydrology. It may have negative implications for the future of alligator populations in this region, particularly if habitat conditions do not favor recruitment of offspring in the near term. Our study provides a foundation to improve inferences made from nightlight surveys of other crocodilian populations.

    1981-01-01

    The difficulties of a comprehensive review of the broad and diverse branches of molecular and solid-state luminescence research are noted. This review is thus limited to selective topics. Some general concepts and trends are then introduced, including: luminescence excitation as a collective excitation of a many-body problem, encompassing in some cases the source and probe in its formulation; continuing trends towards extremal conditions of experiments and towards inhomogeneous and structured materials, from man-made superlattices to biological materials; and increased attention to applications of luminescence research to lamps, displays, solar devices and biological research. Representative recent and new specific research areas include: site selection spectroscopy and 'hole burning'; picosecond delayed coherent anti-Stokes Raman scattering; computer simulation of dynamical processes in luminescence; electron-hole expansion from the Fermi pressure of e-h plasmas; and hot electron phenomena and hot luminescence. Finally some pending problems in luminescence research, such as reconciling the configuration coordinate model and the electronic band theory and clarifying multi-phonon non-radiative processes, are discussed.

  14. Emerging trends in peer review—a survey

    Walker, Richard; Rocha da Silva, Pascal

    2015-01-01

    “Classical peer review” has been subject to intense criticism for slowing down the publication process, bias against specific categories of paper and author, unreliability, inability to detect errors and fraud, unethical practices, and the lack of recognition for unpaid reviewers. This paper surveys innovative forms of peer review that attempt to address these issues. Based on an initial literature review, we construct a sample of 82 channels of scientific communication covering all forms of review identified by the survey, and analyze the review mechanisms used by each channel. We identify two major trends: the rapidly expanding role of preprint servers (e.g., ArXiv) that dispense with traditional peer review altogether, and the growth of “non-selective review,” focusing on papers' scientific quality rather than their perceived importance and novelty. Other potentially important developments include forms of “open review,” which remove reviewer anonymity, and interactive review, as well as new mechanisms for post-publication review and out-of-channel reader commentary, especially critical commentary targeting high profile papers. One of the strongest findings of the survey is the persistence of major differences between the peer review processes used by different disciplines. None of these differences is likely to disappear in the foreseeable future. The most likely scenario for the coming years is thus continued diversification, in which different review mechanisms serve different author, reader, and publisher needs. Relatively little is known about the impact of these innovations on the problems they address. These are important questions for future quantitative research. PMID:26074753

    An attempt was made to analyze the trends in the development of exotic-atom research on the basis of a recently compiled bibliography. The analysis of nearly 4000 publications demonstrated that: (1) exotic atoms are nuclear probes used in every field of physics, from the test of quantum electrodynamics (QED) to chemical physics, to materials sciences; (2) the role of nuclear and atomic physics in exotic atom research is decreasing (although it is still significant), while that of materials sciences and chemial physics is exponentially increasing; and (3) prior to 1980 most investigators were mainly interested in atoms with negative muons, while during the last few years the positive muon (μSR) studies have dominated exotic atom research

    The connotation, progress, research frontiers and developmental trend of grassland agroecology are discussed in this paper. The interface theory, structure and function, coupling and discordance, and health assessment of grassland agroecosystems were recognized as the four research frontiers of the discipline. There exist three primary interfaces in a grassland agroecosystem, i.e., vegetation-site, grassland-animal and production-management. Research into a series of the ecological processes that occurred at these interfaces is the key to revealing the features of the system behavior. There are four sections in a grassland agroecosystem, i.e., pre-plant, plant, animal and post-biotic sections. System coupling and discordance are the two important concepts to describe interactions among the production sections. System coupling among the sections can lead to system improvement by exerting the potential of system capacity. Health of an ecosystem is a reflection of its structure and function, and health assessment is a measurement of its orderliness and service value.

    In this paper is studied the state of the art in order to identify the main trends of the processes of thermo conversion of biomass into fuels and other chemicals. In Cuba, from total supply of biomass, wood is the 19% and sugar cane bagasse and straw the 80%, is why research in the country, should be directed primarily toward these. The methods for energy production from biomass can be group into two classes: thermo-chemical and biological conversion routes. The technology of thermo-chemical conversion includes three subclasses: pyrolysis, gasification, and direct liquefaction. Although pyrolysis is still under development, in the current energy scenario, has received special attention, because can convert directly biomass into solid, liquid and gaseous by thermal decomposition in absence of oxygen. The gasification of biomass is a thermal treatment, where great quantities of gaseous products and small quantities of char and ash are produced. In Cuba, studies of biomass thermo-conversion studies are limited to slow pyrolysis and gasification; but gas fuels, by biomass, are mainly obtained by digestion (biogas). (author)

    Human error has been the problem in all industries. In 1988, the Bureau of Mines, Department of the Interior, USA, carried out the worldwide survey on the human error in all industries in relation to the fatal accidents in mines. There was difference in the results according to the methods of collecting data, but the proportion that human error took in the total accidents distributed in the wide range of 20∼85%, and was 35% on the average. The rate of occurrence of accidents and troubles in Japanese nuclear power stations is shown, and the rate of occurrence of human error is 0∼0.5 cases/reactor-year, which did not much vary. Therefore, the proportion that human error took in the total tended to increase, and it has become important to reduce human error for lowering the rate of occurrence of accidents and troubles hereafter. After the TMI accident in 1979 in USA, the research on man-machine interface became active, and after the Chernobyl accident in 1986 in USSR, the problem of organization and management has been studied. In Japan, 'Safety 21' was drawn up by the Advisory Committee for Energy, and also the annual reports on nuclear safety pointed out the importance of human factors. The state of the research on human factors in Japan and abroad and three targets to reduce human error are reported. (K.I.)

    2011-01-01

    Research interests in addressing construction and demolition (C and D) waste management issues have resulted in a large amount of publications during the last decade. This study demonstrates that there is no systematic examination on the research development in literature in the discipline of C and D waste management. This study presents the latest research trend in the discipline through analyzing the publications from 2000 to 2009 in eight major international journals. The analysis is conducted on the number of papers published annually, main authors' contributions, research methods and data analysis methods adopted, and research topics covered. The results exhibit an increasing research interest in C and D waste management in recent years. Researchers from developed economies have contributed significantly to the development of the research in the discipline. Some developing countries such as Malaysia and China have also been making good efforts in promoting C and D waste management research. The findings from this study also indicate that survey and case study are major methods for data collection, and the data are mostly processed through descriptive analysis. It is anticipated that more future studies on C and D waste management will be led by researchers from developing economies, where construction works will remain their major economic activities. On the other hand, more sophisticated modeling and simulating techniques have been used effectively in a number of studies on C and D waste management research, and this is considered a major methodology for future research in the discipline. C and D waste management will continue to be a hot research topic in the future, in particularly, the importance of human factors in C and D waste management has emerged as a new challenging topic.

    Research interests in addressing construction and demolition (C&D) waste management issues have resulted in a large amount of publications during the last decade. This study demonstrates that there is no systematic examination on the research development in literature in the discipline of C&D waste management. This study presents the latest research trend in the discipline through analyzing the publications from 2000 to 2009 in eight major international journals. The analysis is conducted on the number of papers published annually, main authors' contributions, research methods and data analysis methods adopted, and research topics covered. The results exhibit an increasing research interest in C&D waste management in recent years. Researchers from developed economies have contributed significantly to the development of the research in the discipline. Some developing countries such as Malaysia and China have also been making good efforts in promoting C&D waste management research. The findings from this study also indicate that survey and case study are major methods for data collection, and the data are mostly processed through descriptive analysis. It is anticipated that more future studies on C&D waste management will be led by researchers from developing economies, where construction works will remain their major economic activities. On the other hand, more sophisticated modeling and simulating techniques have been used effectively in a number of studies on C&D waste management research, and this is considered a major methodology for future research in the discipline. C&D waste management will continue to be a hot research topic in the future, in particularly, the importance of human factors in C&D waste management has emerged as a new challenging topic.

    Full Text Available Medical tourism is a modern concept, but not a new tourism practice. Even there is still no international consent on the definitions and measurement of this trend, its importance in the development of a tourism destination started to be taken into consideration. In accordance with tourism segment classification depending on journey reasons recommended by World Tourism Organization, one of the main groups is for “medical treatment/health”. Being part of health tourism, medical tourism is often called medical travel because it includes the act of travelling to different countries for medical reasons. An increasing significant element in medical service trade is patient circulation at cross-border level with a view to obtaining necessary health services; this circulation generated a new phenomenon, namely medical tourism. Studying the scientific literature we find new medical tourism trends in connection with globalization and liberalization. The countries that decided to promote this niche tourism are aware of the huge economic benefits brought by this. Analyzing published data by tourism medical organizations associated to indicators of economic development, we find two aspects: the success of a medical tourism destination is influenced by the economical level of the receiving countries, but, at the same time, it is also a growth factor for developing economies if it is included in their national strategy. We intend to find the answer of several questions: trends in medical tourism development are involving only medical service trade, or a combination of specific activities of many sectors? Is the medical tourism acting in favor of developing economies? This study aims to notice the development trends of the medical tourism based on the published figures and on the experience of major destinations and to highlight the importance of the medical tourism for the developing economies.

    Jones, Lisa M; Mitchell, Kimberly J; Finkelhor, David

    2012-02-01

    The purpose of this research was to explore the trends in youth reports of unwanted online sexual solicitation, harassment, and exposure to pornography over time. The study was based on three separate cross-sectional national telephone surveys of approximately 1,500 youth Internet users, aged 10 through 17 years. Data were collected in 2000, 2005, and 2010. Nine percent of youth reported an unwanted sexual solicitation in 2010. This continued the decline in unwanted sexual solicitations that occurred between 2000 (19%) and 2005 (13%), resulting in a total 50% decrease between 2000 and 2010. Twenty-three percent of youth reported an unwanted exposure to pornography, a decline from 34% in 2005, following an increase between 2000 and 2005 (25% to 34%). However, marking the only trend to show an increase over the past 5 years, 11% of youth reported an online harassment experience, which was an increase from 9% in 2005, and 6% in 2000. Some differences in these trends were noted for subgroups of youth across age, gender, and race. The trends in unwanted experiences online over the past decade identified by three Youth Internet Safety Surveys may contradict impressions that the general population, professionals, and the media have about what is happening. Trends provide evidence for some optimism that protective adaptations to the online environment have been successful; however, online harassment appears to be increasing for youth, particularly girls, and may require additional mobilization.

    Weingarten, Carol P; Strauman, Timothy J

    2015-01-01

    This article reviews neuroimaging studies that inform psychotherapy research. An introduction to neuroimaging methods is provided as background for the increasingly sophisticated breadth of methods and findings appearing in psychotherapy research. We compiled and assessed a comprehensive list of neuroimaging studies of psychotherapy outcome, along with selected examples of other types of studies that also are relevant to psychotherapy research. We emphasized magnetic resonance imaging (MRI) since it is the dominant neuroimaging modality in psychological research. We summarize findings from neuroimaging studies of psychotherapy outcome, including treatment for depression, obsessive compulsive disorder (OCD), and schizophrenia. The increasing use of neuroimaging methods in the study of psychotherapy continues to refine our understanding of both outcome and process. We suggest possible directions for future neuroimaging studies in psychotherapy research.

  18. [Trends and perspectives in health personnel research in the Americas].

    Science.gov (United States)

    Nogueira, R P

    1985-01-01

    It is paradoxical that the lion's share (60 to 80%) of the health budgets of the countries is invested in meeting the personnel costs of the system, and yet few studies have been done to assess the production of that personnel. The importance of personnel as a basic constituent of the sector and its presence at all levels of medical care (from physicians to auxiliaries) makes it vitally important to know how it has evolved over time so that trends can be anticipated and policies guided accordingly. This work seeks to fill, at least partly, the information gap on this subject. The method by which the author has chosen to make this evaluation is to examine the published literature on health personnel, inasmuch as the situation is reflected in articles and documents on the subject. He therefore examined the general trends observed in the following specific areas: increase of personnel and medical schools, the upsurge in the international migration of physicians, changes in the pace of personnel production, emphasis on the integration of services and education, etc. After a detailed analysis of the articles in Educación médica y salud and the Index Medicus Latinoamericano classified by subjects, the author concludes that, although much has been written on health personnel, little in-depth research has been done in primary data sources, and what is done is predominantly surveys. Besides, this research is concerned essentially with the curriculum and organization of university instruction, and betrays a great concern with coverage extension and primary care and with the training and use of auxiliary personnel, planning, and continuing education.

    1981-01-01

    With the operation of a fuel reprocessing plant in the Power Reactor and Nuclear Fuel Development Corporation (PNC) and the plan for a second fuel reprocessing plant, the research on fuel reprocessing safety, along with the reprocessing technology itself, has become increasingly important. As compared with the case of LWR power plants, the safety research in this field still lags behind. In the safety of fuel reprocessing, there are the aspects of keeping radiation exposure as low as possible in both personnel and local people, the high reliability of the plant operation and the securing of public safety in accidents. Safety research is then required to establish the safety standards and to raise the rate of plant operation associated with safety. The following matters are described: basic ideas for the safety design, safety features in fuel reprocessing, safety guideline and standards, and safety research for fuel reprocessing. (J.P.N.)

  4. NEW THEORETICAL RESEARCH TRENDS IN CARTOGRAPHY

    Directory of Open Access Journals (Sweden)

    Robert S. Sluter, Jr.

    2001-12-01

    Full Text Available Cartography has been defined as the art, science, and technology of map-making. Until the middle of the 20th Century, cartography was more an art than a science. Beginning in the 1950's, cartographic researchers began to take a more scientific approach to map-making with Robinson's The Look of Maps. In the 1970's, many researchers adopted a communications paradigm for cartography, understanding maps as tools for the communication of information from cartographer to map user. Under this paradigm, cartographers attempted to find the "optimal" map that would communicate known information to the map-reader with as little "noise" as possible. With the rapid progress in computer technology afforded by the ubiquitous personal computer, in the last decade a number of cartographic researchers, led by Alan MacEachren, have suggested a new way of understanding how maps work No longer seen as simply tools for communicating known information, maps can be employed to discover the unknown patterns in any phenomenon that possesses a spatial dimension. Rather than attempting to construct the "best" map, modern computer technology can allow for the construction of a multitude of representations of a phenomenon that can be used to answer different questions posed by individual researchers and reveal hitherto unrealized patterns in the data (data exploration. This new approach is termed "cartographic visualization". Based upon research in other fields, including computer graphics, the neurophysiology of the eye-brain system, cognitive science, and semiotics (the science of symbol systems, this newest thrust in cartographic theory has opened up broad new horizons for cartographic research. This has energized the discipline and promises to lead to new insights which will enable us to make better maps. This paper outlines these new approaches to cartographic research.

    2018-03-01

    A deep bibliometric analysis has been carried out, obtaining valuable parameters that facilitate the understanding around the research in plant using molecular markers. The evolution of the improvement in the field of agronomy is fundamental for its adaptation to the new exigencies that the current world context raises. In addition, within these improvements, this article focuses on those related to the biotechnology sector. More specifically, the use of DNA markers that allow the researcher to know the set of genes associated with a particular quantitative trait or QTL. The use of molecular markers is widely extended, including: restriction fragment length polymorphism, random-amplified polymorphic DNA, amplified fragment length polymorphism, microsatellites, and single-nucleotide polymorphisms. In addition to classical methodology, new approaches based on the next generation sequencing are proving to be fundamental. In this article, a historical review of the molecular markers traditionally used in plants, since its birth and how the new molecular tools facilitate the work of plant breeders is carried out. The evolution of the most studied cultures from the point of view of molecular markers is also reviewed and other parameters whose prior knowledge can facilitate the approach of researchers to this field of research are analyzed. The bibliometric analysis of molecular markers in plants shows that top five countries in this research are: US, China, India, France, and Germany, and from 2013, this research is led by China. On the other hand, the basic research using Arabidopsis is deeper in France and Germany, while other countries focused its efforts in their main crops as the US for wheat or maize, while China and India for wheat and rice.

    Innovation represents a core value of the American Rhinologic Society (ARS), with multiple efforts to promote research in the advancement rhinologic care. We therefore sought to identify trends in extramural sinusitis funding and underutilized sources of support to facilitate future efforts. A systematic review of the National Institutes of Health (NIH) Research Portfolio Online Tools (RePORTER) database (fiscal year 1993 to 2017) was completed with the search strategy: ("chronic sinusitis" OR rhinosinusitis). All identified studies were accepted for review, with comparison to ARS membership rolls to identify studies supported by ARS investigators. Foundation awards were surveyed to identify and characterize additional sources of support. The systematic review identified 958 projects receiving NIH funding, of which 120 remain active. The percentage of sinusitis-related awards and total funding relative to all NIH awards increased over the past 10 years (2006 to 2016) from 0.06% (8 / 9128) and 0.09% ($2,151,152 / $3,358,338,602) to 0.87% (86 / 9540) and 0.90% ($37,201,095 / $4,300,145,614). Among active studies, 9 investigators maintain membership in the ARS and serve as principal investigator or project leader in 12 (10%) studies. ARS investigators received the greatest number of awards from the National Institute on Deafness and Other Communication Disrders (n = 8,66.7%), while only receiving 2.2% of awarded funding from the National Institute of Allergy and Infectious Diseases ($607,500/$26,873,022), the largest source of awards for sinusitis research. Support for sinusitis research is significantly growing, with the largest source of active funding not being fully utilized by members of the ARS. Further efforts to promote funding priorities among extramural sources is necessary to facilitate increased funding for ARS member initiatives. © 2017 ARS-AAOA, LLC.

  20. Wireless transmission: state of research, applications, trends

    Berger, A.

    2016-01-01

    At the end of the 19th century Nikola Tesla started his work in the field of wireless energy transmission. More than 100 years after Tesla, the progress in modern semiconductor technology offer developers the possibility to realize highly efficient systems and have led to a revival of wireless energy transmission. The application ranges from the transmission of a few milliwatts in biomedical applications, over a few watts for the charging of mobile phones, to hundreds of kilowatts in the automotive sector. Depending on the used method, the possible transmission distances vary between a few centimeters up to thousands of kilometers. The physical basis of these technologies is the transmission of energy by electromagnetic waves. State-of-the-art systems use wavelengths ranging from radio waves to microwaves, to ultraviolet light. Current research focuses on optimizing transmission efficiency, increasing the possible transmission distance between transmitter and receiver, and improving spatial freedom of movement. This lecture gives an overview of the different approaches of wireless energy transmission and their physical background, the established industrial standards and the current state of research. In addition, the advantages and disadvantages of the individual methods are illustrated by selected commercial and scientific applications. (rössner) [de

    Purpose: To test the hypothesis that recent resident research productivity might be different than a decade ago, and to provide contemporary information about resident scholarly activity. Methods and Materials: We compiled a list of radiation oncology residents from the 2 most recent graduating classes (June 2014 and 2015) using the Association of Residents in Radiation Oncology annual directories. We queried the PubMed database for each resident's first-authored publications from postgraduate years (PGY) 2 through 5, plus a 3-month period after residency completion. We abstracted corresponding historical data for 2002 to 2007 from the benchmark publication by Morgan and colleagues (Int J Radiat Oncol Biol Phys 2009;74:1567-1572). We tested the null hypothesis that these 2 samples had the same distribution for number of publications using the Wilcoxon rank-sum test. We explored the association of demographic factors and publication number using multivariable zero-inflated Poisson regression. Results: There were 334 residents publishing 659 eligible first-author publications during residency (range 0-17; interquartile range 0-3; mean 2.0; median 1). The contemporary and historical distributions were significantly different (P<.001); contemporary publication rates were higher. Publications accrued late in residency (27% in PGY-4, 59% in PGY-5), and most were original research (75%). In the historical cohort, half of all articles were published in 3 journals; in contrast, the top half of contemporary publications were spread over 10 journals—most commonly International Journal of Radiation Oncology • Biology • Physics (17%), Practical Radiation Oncology (7%), and Radiation Oncology (4%). Male gender, non-PhD status, and larger residency size were associated with higher number of publications in the multivariable analysis. Conclusion: We observed an increase in first-author publications during training compared with historical data from the mid-2000s. These

  5. Trends in fusion reactor safety research

    1991-01-01

    Fusion has the potential to be an attractive energy source. From the safety and environmental perspective, fusion must avoid concerns about catastrophic accidents and unsolvable waste disposal. In addition, fusion must achieve an acceptable level of risk from operational accidents that result in public exposure and economic loss. Finally, fusion reactors must control routine radioactive effluent, particularly tritium. Major progress in achieving this potential rests on development of low-activation materials or alternative fuels. The safety and performance of various material choices and fuels for commercial fusion reactors can be investigated relatively inexpensively through reactor design studies. These studies bring together experts in a wide range of backgrounds and force the group to either agree on a reactor design or identify areas for further study. Fusion reactors will be complex with distributed radioactive inventories. The next generation of experiments will be critical in demonstrating that acceptable levels of safe operation can be achieved. These machines will use materials which are available today and for which a large database exists (e.g. for 316 stainless steel). Researchers have developed a good understanding of the risks associated with operation of these devices. Specifically, consequences from coolant system failures, loss of vacuum events, tritium releases, and liquid metal reactions have been studied. Recent studies go beyond next step designs and investigate commercial reactor concerns including tritium release and liquid metal reactions. 18 refs

  8. New trends in the nucleation research

    During the last half of century the most of efforts have been directed towards small molecule system modeling using intermolecular potentials. Summarizing the nucleation theory, it can be concluded that the nowadays theory is far from complete. The vapor-gas nucleation theory can produce values that deviate from the experimental results by several orders of magnitude currently. Experiments on the vapor-gas nucleation rate measurements using different devices show significant inconsistencies in the measured rates as well. Theoretical results generally are quite reasonable for sufficiently low vapor nucleation rates where the capillary approximation is applicable. In the present research the advantages and current problems of the vapor-gas nucleation experiments are discussed briefly and a view of the future studies is presented. Using the brake points of the first derivative for the nucleation rate surface as markers of the critical embryos phase change is fresh idea to show the gas-pressure effect for the nucleating vapor-gas systems. To test the accuracy of experimental techniques, it is important to have a standard system that can be measured over a range of nucleation conditions. Several results illustrate that high-pressure techniques are needed to study multi-channel nucleation. In practical applications, parametric theories can be used for the systems of interest. However, experimental measurements are still the best source of information on nucleation rates. Experiments are labor intensive and costly, and thus, it is useful to extend the value of limited experimental measurements to a broader range of nucleation conditions. Only limited experimental data one needs for use in normalizing the slopes of the linearized nucleation rate surfaces. The nucleation rate surface is described in terms of steady-state nucleation rates. It is supposed that several new measuring systems, such as High Pressure Flow Diffusion Chamber for pressure limit up to 150 bar will be

  9. Trends in eutrophication research and control

    Science.gov (United States)

    Rast, Walter; Thornton, Jeffrey A.

    1996-02-01

    Eutrophication is the natural ageing process of lakes. It is characterized by a geologically slow shift from in-lake biological production driven by allochthonous (external to the water body) loading of nutrients, to production driven by autochthonous (in-lake) processes. This shift typically is accompanied by changes in species and biotic community composition, as an aquatic ecosystem is ultimately transformed into a terrestrial biome. However, this typically slow process can be greatly accelerated by human intervention in the natural biogeochemical cycling of nutrients within a watershed; the resulting cultural eutrophication can create conditions inimical to the continued use of the water body for human-driven economic purposes. Excessive algal and rooted plant growth, degraded water quality, extensive deoxygenation of the bottom water layers and increased fish biomass accompanied by decreased harvest quality, are some features of this process.Following the Second World War, concern with cultural eutrophication achieved an intensity that spurred a significant research effort, culminating in the identification of phosphorus as the single most significant, and controllable, element involved in driving the eutrophication process. During the late 1960s and throughout the 1970s, much effort was devoted to reducing phosphorus in wastewater effluents, primarily in the developed countries of the temperate zone. These efforts generally resulted in the control of eutrophication in these countries, albeit with varying degrees of success. The present effort in the temperature zone, comprising mostly developed nations, has now shifted to the control of diffuse sources of a broader spectrum of contaminants that impact human water use.In the developing countries of the inter-tropical zone, however, rapidly expanding populations, a growing industrial economy and extensive urbanization have only recently reached an intensity at which cultural eutrophication can no longer be

    The benefits of physical activity are established, however, increasing population physical activity levels remains a challenge. Participating in activities that are enjoyable and multidimensional, such as dancing, are associated with better adherence. However, the extent to which the general population participates in dancing and its temporal trends has not been well studied. The aim of this study was to investigate temporal trends and patterns and correlates of dance participation in England from 1994 to 2012 using a series of large nationally representative surveys. We used data from the Health Survey for England 1994, 1997, 1998, 1999, 2003, 2004, 2006, 2008 and 2012 to examine dance temporal trends. Temporal trends data were age-standardized and correlates of dance participation were examined for males and females over each study year. Changes in population prevalence of dance participation were determined using multiple logistical regression with 1997 as the reference year. Of all survey participants (n=98,178) 7.8% (95%CI: 7.63-7.96) reported dance participation. There was a marked steady decrease over time, with the steepest decline from 2003 onwards. The multivariable-adjusted odds ratios for dance participation were 0.51 for males (95%CI 0.408-0.630, p<0.001) and 0.69 for females (95%CI: 0.598-0.973, p<0.001) in 2012 compared to 1997. Dance participation in adults in England has decreased markedly over time. This study suggests that dance is not being adequately utilized as a health enhancing physical activity, and therefore further research and resources should be dedicated to supporting dance in the community.

    Create a screening measure of health literacy for use with the Health Information National Trends Survey (HINTS). Participants completed a paper-based survey. Items from the survey were used to construct a health literacy screening measure. A population-based survey conducted in geographic areas of high and low minority frequency and in Central Appalachia. Two thousand nine hundred four English-speaking participants were included in this study: 66% white, 93% completed high school, mean age = 52.53 years (SD = 16.24). A health literacy screening measure was created using four items included in the HINTS survey. Scores could range from 0 (no questions affirmative/correct) to 4 (all questions answered affirmatively/correctly). Multiple regression analysis was used to determine whether demographic variables known to predict health literacy were indeed associated with the constructed health literacy screening measure. The weighted average health literacy score was 2.63 (SD = 1.00). Those who were nonwhite (p = .0005), were older (p literacy screening measure scores. This study highlights the need to assess health literacy in national surveys, but also serves as evidence that screening measures can be created within existing datasets to give researchers the ability to consider the impact of health literacy. © The Author(s) 2016.

    1994-01-01

    The mourning dove (Zenaida macroura) Callcount Survey and the North American Breeding Bird Survey provide information on population trends of mourning doves throughout the continental United States. Because surveys are an integral part of the development of hunting regulations, a need exists to determine which survey provides precise information. We estimated population trends from 1966 to 1988 by state and dove management unit, and assessed the relative efficiency of each survey. Estimates of population trend differ (P lt 0.05) between surveys in 11 of 48 states; 9 of 11 states with divergent results occur in the Eastern Management Unit. Differences were probably a consequence of smaller sample sizes in the Callcount Survey. The Breeding Bird Survey generally provided trend estimates with smaller variances than did the Callcount Survey. Although the Callcount Survey probably provides more withinroute accuracy because of survey methods and timing, the Breeding Bird Survey has a larger sample size of survey routes and greater consistency of coverage in the Eastern Unit.

    Adoption involves the legal transfer of parental rights and responsibilities from a child's birth parents to adults who will raise the child (Reitz & Watson, 1992). Research related to adoption has expanded over the past 10 years and has incorporated more focus on implications for practice and public policy. This expansion has reflected increased awareness of the lived experience of adopted individuals, in addition to that of adoptive families and birth or first parents and families, collectively known as the adoption kinship network (Grotevant & McRoy, 1998). Trends discussed included research and social trends or movements (2007-2017) since the publication of the final article in a series of articles in the psychological literature related to adoption in The Counseling Psychologist (Baden & Wiley, 2007; Lee, 2003; O'Brien & Zamostny, 2003; Wiley & Baden, 2005; Zamostny, O'Brien, Baden, & Wiley, 2003; Zamostny, Wiley, O'Brien, Lee, & Baden, 2003). This article summarizes the social trends and research related to adoption over the last 10 years, including longitudinal and meta-analytic studies, increased research and conceptualization of ethnic and racial identity development, research on microaggressions, and research on diverse adoptive families, including those with gay and lesbian parents. Social trends included increased knowledge related to Internet accessibility, genetic information, continued focus on openness, and viewing adoption through a more critical lens. Implications are discussed for the development of programs that enhance competence of mental health professionals and adoption professionals in adoption-competent practice.

    Surveys are one of the most frequently employed study designs in healthcare epidemiology research. Generally easier to undertake and less costly than many other study designs, surveys can be invaluable to gain insights into opinions and practices in large samples and may be descriptive and/or be used to test associations. In this context, qualitative research methods may complement this study design either at the survey development phase and/or at the interpretation/extension of results stage. This methods article focuses on key considerations for designing and deploying surveys in healthcare epidemiology and antibiotic stewardship, including identification of whether or not de novo survey development is necessary, ways to optimally lay out and display a survey, denominator measurement, discussion of biases to keep in mind particularly in research using surveys, and the role of qualitative research methods to complement surveys. We review examples of surveys in healthcare epidemiology and antimicrobial stewardship and review the pros and cons of methods used. A checklist is provided to help aid design and deployment of surveys in healthcare epidemiology and antimicrobial stewardship. Infect Control Hosp Epidemiol 2016;1-6.

    2016-01-01

    In recent times, when energy crisis compounded by global warming and climate change is receiving worldwide attention, the emergence of algae, as a better feedstock for third-generation biofuels than energy crops or plants, holds great promise. As compared to conventional biofuels feedstocks, algae offer several advantages and can alone produce a significant amount of biofuels sustainably in a shorter period to fulfill the rising demand for energy. Towards commercialisation, there have been numerous efforts put for- ward for the development of algae-derived biofuel. This article reviews and summarizes the recent inventions and the current trends that are reported and captured in relevant patents pertaining to the novel methods of algae biomass cultivation and processing for biofuels and value-added products. In addition, the recent advancement in techniques and technologies for microalgal biofuel production has been highlighted. Various steps involved in the production of algal biofuels have been considered in this article. Moreover, the work that advances to improve the efficiency and cost-effectiveness of the processes for the manufacture of biofuels has been presented. Our survey was conducted in the patent databases: WIPO, Spacenet and USPTO. There are still some technological bottlenecks that could be overcome by designing advanced photobioreactor and raceway ponds, developing new and low cost technologies for biomass cultivation, harvesting, drying and extraction. Recent advancement in algae biofuels methods is directed toward developing efficient and integrated systems to produce biofuels by overcoming the current challenges. However, further research effort is required to scale-up and improve the efficiency of these methods in the upstream and downstream technologies to make the cost of biofuels competitive with petroleum fuels.

  17. Global Survey on Future Trends in Human Spaceflight: the Implications for Space Tourism

    Science.gov (United States)

    Gurtuna, O.; Garneau, S.

    2002-01-01

    With the much-publicized first ever space tourist flight, of Dennis Tito, and the announcement of the second space tourist flight to take place in April 2002, it is clear that an alternative motivation for human spaceflight has emerged. Human spaceflight is no longer only about meeting the priorities of national governments and space agencies, but is also about the tangible possibility of ordinary people seeing the Earth from a previously exclusive vantage point. It is imperative that major space players look beyond the existing human spaceflight rationale to identify some of the major driving forces behind space tourism, including the evolving market potential and developments in enabling technologies. In order to determine the influence of these forces on the future of commercial human spaceflight, the responses of a Futuraspace survey on future trends in human spaceflight are analyzed and presented. The motivation of this study is to identify sought-after space destinations, explore the expected trends in enabling technologies, and understand the future role of emerging space players. The survey will reflect the opinions of respondents from around the world including North America, Europe (including Russia) and Asia. The profiles of targeted respondents from space industry, government and academia are high-level executives/managers, senior researchers, as well as former and current astronauts. The survey instrument is a questionnaire which is validated by a pilot study. The sampling method is non-probabilistic, targeting as many space experts as possible who fit our intended respondent profile. Descriptive and comparative statistical analysis methods are implemented to investigate both global and regional perceptions of future commercial trends in human spaceflight. This study is not intended to be a formal market study of the potential viability of the space tourism market. Instead, the focus is on the future trends of human spaceflight, by drawing on the

    The role of a fusion neutron radiation test facility in the development of a scientific feasibility experimental reactor or demonstration fusion power reactor plant would be analogous to the role of the materials testing and experimental reactors in the development of fission power reactor. While the material testing fission reactor has been developed after successful operation of fission reactors, in the case of fusion reactor development it is desirable to realize the fusion engineering research facility (FERF) in-phase to the development of SFX and/or demonstration fusion power reactor plants. Here so called FERF in near future is the Controlled Thermonuclear Reactor which provides the high-intensity and high-energy neutron and plasma source whether the net power output is produced or not. From the point of direct attainment to SFX, we would like to emphasize that FEFE is the royal road leading to the goal of successful achievement of CTR program and could be useful for the experiment on impurity effects caused by neutron and plasma irradiations onto the wall material for SFX. Further, we rather suppose that hybrid FERF-fission assembly could be fairly and easily realizable in near future. (auth.)

    2010-08-01

    This study used scientometric methods to conduct an automatic content analysis on the development trends of science education research from the published articles in the four journals of International Journal of Science Education, Journal of Research in Science Teaching, Research in Science Education, and Science Education from 1990 to 2007. The multi-stage clustering technique was employed to investigate with what topics, to what development trends, and from whose contribution that the journal publications constructed as a science education research field. This study found that the research topic of Conceptual Change & Concept Mapping was the most studied topic, although the number of publications has slightly declined in the 2000's. The studies in the themes of Professional Development, Nature of Science and Socio-Scientific Issues, and Conceptual Chang and Analogy were found to be gaining attention over the years. This study also found that, embedded in the most cited references, the supporting disciplines and theories of science education research are constructivist learning, cognitive psychology, pedagogy, and philosophy of science.

  8. Trends in aeropropulsion research and their impact on engineering education

    Povinelli, Louis A.; Reichert, Bruce A.; Glassman, Arthur J.

    1992-01-01

    This presentation is concerned with the trends in aeropropulsion both in the U.S. and abroad and the impact of these trends on the educational process in our universities. In this paper, we shall outline the new directions for research which may be of interest to educators in the aeropropulsion field. Awareness of new emphases, such as emission reductions, noise control, maneuverability, speed, etc., will have a great impact on engineering educators responsible for restructuring courses in propulsion. The information presented herein will also provide some background material for possible consideration in the future development of propulsion courses. In describing aeropropulsion, we are concerned primarily with air-breathing propulsion; however many observations apply equally as well to rocket engine systems. Aeropropulsion research needs are primarily motivated by technologies required for advanced vehicle systems and frequently driven by external requirements such as economic competitiveness, environmental concern and national security. In this presentation, vehicle based research is first described, followed by a discussion of discipline and multidiscipline research necessary to implement the vehicle-focused programs. The importance of collaboration in research and the training of future researchers concludes this presentation.

    The synergistic reaction under specific conditions of the nonlinear system, weak driving signal and moderate noise can make noise to be advantageous in a certain extent, so as to achieve the purpose of signal enhancement, this seemingly anomalous phenomenon is defined as stochastic resonance. In this paper, the weak signal detection under strong noise background is the main line. The principle of white noise to counteract external noise is expounded, and the present research situation and development trend of stochastic resonance are reviewed in that paper, it also pointed out the direction of further research of stochastic resonance technology.

    For doing research on topics in primary care medicine participation of primary care physicians is necessary. Research in this field of medicine is only marginally established in Switzerland. In a postal survey we evaluate the general attitudes of physicians towards research in the field of primary care. In particular we were interested in their willingness to participate in research projects and the facilitating and impeding factors to take part in such projects. A purpose designed questionnaire was sent by post to 3044 primary care physicians in the central and eastern parts of Switzerland. The return rate was 52%. A majority of 94% of the responding physicians revealed interest in primary care research and 60% of all responders are willing to participate actively in such projects. They are prepared to spend about 15 min a day for data acquisition. Their willingness to participate depends on the conditions that, first, the research topic is relevant for daily practice and, second, boards odder Continuous Medical Education credits for time spent for research. Time constraints, additional administrative work and lack of relevance of research topics to daily practice are the main barriers. This survey demonstrates the general interest of primary care physicians to participate in relevant research projects. Therefore the structure to set up such research should be established.

    It would be a truism to say that the trends in the area of proliferation display positive and negative aspects. On the one hand, the steps being taken by the nuclear haves appear to be designed to maintain their nuclear hegemony forever; on the other, there are indications such as the support being extended to the proposed conventions for the ending of nuclear tests and the production of fissile material for weapons that the nuclear weapons states also realize that the problem cannot be solved unless they also participate in the process and accept non-discriminatory restraints. However, it is much too early to predict which way the situation will develop. (author). 34 refs

    Survey data remain a crucial means for monitoring alcohol consumption, but there has been limited work done to ensure that surveys adequately capture changes in per-capita consumption in Australia. In this study, we explore how trends in consumption from two major Australian surveys compare with an official measure of per-capita consumption between 2001 and 2014 and examine age-specific trends in drinking. Data were from five waves of the cross-sectional National Health Survey (total n = 113 279) and 12 waves of the longitudinal Household Income and Labour Dynamics in Australia Study (average n = 12 347). Overall and age-specific estimates of annual alcohol consumption were derived and compared with official per-capita consumption and previous analyses of the National Drug Strategy Household Survey. In terms of overall consumption, both surveys broadly reflected trends in per-capita consumption, especially the decline that has been observed since 2007/2008. Age-specific trends were broadly similar, with the recent decline in consumption clearly concentrated among teenagers and young adults. The main Australian monitoring surveys remain useful monitoring tools for alcohol consumption in Australia. There is consistent evidence that the recent declines in Australian per-capita consumption have been driven by sharp falls in drinking among young people, a trend that requires further study.

    We are consistently being exposed to nanomaterials in direct and/or indirect route as they are used in almost all the sectors in our life. Nations across the worlds are now trying to put global regulation policy on nanomaterials. Sometimes, they are reported to be more toxic than the corresponding ion and micromaterials. Therefore, safety research of nanoparticles has huge implications on a national economics. In this study, we evaluated and analyzed the research trend of ecotoxicity of nanoparticles in soil environment. Test species include terrestrial plants, earthworms, and soil nematode. Soil enzyme activities were also discussed. We found that the results of nanotoxicity studies were affected by many factors such as physicochemical properties, size, dispersion method and test medium of nanoparticle, which should be considered when conducting toxicity researches. In particular, more researches on the effect of physico chemical properties and fate of nanoparticles on toxicity effect should be conducted consistently. PMID:24278532

    Full Text Available This paper presents an overview of major trends in archaeological network research through a bibliometric analysis of the full corpus of publications on the topic between 1965 and 2016. It illustrates we can begin identifying the outlines of a new sub-discipline within archaeology with its distinct traditions, including a diversity of research approaches, dedicated events and preferred publication venues. This sub-discipline is at a similar stage of development as historical network research, and we argue that archaeologists and historians alike interested in establishing network research as a key tool for exploring social change will have a greater chance for success to the extent that we actively collaborate, pool resources, engage in common community activities and publications, and learn from each other’s mistakes.

    In the last few decades, health systems research (HSR) has garnered much attention with a rapid increase in the related literature. This study aims to review and evaluate the global progress in HSR and assess the current quantitative trends. Based on data from the Web of Science database, scientometric methods and knowledge visualization techniques were applied to evaluate global scientific production and develop trends of HSR from 1900 to 2012. HSR has increased rapidly over the past 20 years. Currently, there are 28,787 research articles published in 3,674 journals that are listed in 140 Web of Science subject categories. The research in this field has mainly focused on public, environmental and occupational health (6,178, 21.46%), health care sciences and services (5,840, 20.29%), and general and internal medicine (3,783, 13.14%). The top 10 journals had published 2,969 (10.31%) articles and received 5,229 local citations and 40,271 global citations. The top 20 authors together contributed 628 papers, which accounted for a 2.18% share in the cumulative worldwide publications. The most productive author was McKee, from the London School of Hygiene & Tropical Medicine, with 48 articles. In addition, USA and American institutions ranked the first in health system research productivity, with high citation times, followed by the UK and Canada. HSR is an interdisciplinary area. Organization for Economic Co-operation and Development countries showed they are the leading nations in HSR. Meanwhile, American and Canadian institutions and the World Health Organization play a dominant role in the production, collaboration, and citation of high quality articles. Moreover, health policy and analysis research, health systems and sub-systems research, healthcare and services research, health, epidemiology and economics of communicable and non-communicable diseases, primary care research, health economics and health costs, and pharmacy of hospital have been identified as the

    Blum, P.T.

    1986-01-01

    This survey reviews Radioactive Waste (RW) transports in different countries, giving the origins, amounts, distances and modes of transport for the different RW categories currently moved. It appears that: present transport experience concerns mainly Low and Medium level Wastes (LMW) and Spent nuclear Fuel (SF); RW transports are implemented in compliance with IAEA recommendations which proved particularly helpful to gain public acceptance; the bulk of LMW is transported as Low Specific Activity (LSA) materials (i.e. with packaging requirements just equivalent to those needed for their disposal) and SF as well as liquid RW are transported in 'type B' packagings which withstand severe accident conditions; records indicate that transport worker irradiation is kept much below allowable limits and that accidents during RW transports did not cause significant release of activity to environment; and the cost of RW transports including insurances, is small compared to that of RW processing and disposal. Therefore, one may comment that RW movements are by no means slowed down by transport problems and just follow the demand which in some countries may be delayed by reasons linked to RW disposal strategy or its public acceptance. This survey presents also an assessment of RW transports until the end of this century

  19. How Do Trend Researchers Conduct Research? The Production of Knowledge in a Controversial Field

    Directory of Open Access Journals (Sweden)

    Michaela Pfadenhauer

    2004-05-01

    Full Text Available The planned research project described in this article focuses on the methods of trend research—not only in a narrow literal sense of techniques of data collection and data evaluation but also in a broader understanding of the logic of knowledge production in this controversial field. Initially trend research can be appointed between market research on the one hand and futurology on the other hand. Criticism regarding trend research as well as its innovative potential is also mentioned. Following the recent studies, trend research is conceived as application-oriented research in a broad sense. As far as the methodology is concerned, the proposed study promises to be an empirically-founded contribution by integrating analysis from sources such as explorative and focused conversations, observations and expert interviews. The study uses the example of trend research and asks the question how research is actually "done" and if it is application oriented or not. URN: urn:nbn:de:0114-fqs0402366

  20. A survey of residual analysis and a new test of residual trend.

    McDowell, J J; Calvin, Olivia L; Klapes, Bryan

    2016-05-01

    A survey of residual analysis in behavior-analytic research reveals that existing methods are problematic in one way or another. A new test for residual trends is proposed that avoids the problematic features of the existing methods. It entails fitting cubic polynomials to sets of residuals and comparing their effect sizes to those that would be expected if the sets of residuals were random. To this end, sampling distributions of effect sizes for fits of a cubic polynomial to random data were obtained by generating sets of random standardized residuals of various sizes, n. A cubic polynomial was then fitted to each set of residuals and its effect size was calculated. This yielded a sampling distribution of effect sizes for each n. To test for a residual trend in experimental data, the median effect size of cubic-polynomial fits to sets of experimental residuals can be compared to the median of the corresponding sampling distribution of effect sizes for random residuals using a sign test. An example from the literature, which entailed comparing mathematical and computational models of continuous choice, is used to illustrate the utility of the test. © 2016 Society for the Experimental Analysis of Behavior.

    2005-01-01

    The purpose of this study was to obtain a survey about the present situation including the usage pattern, technical characteristics and the anticipated future of teleradiology in Switzerland. An internet-based questionnaire was made available to all members of the Swiss Society of Radiology. Questions concerning current teleradiology usage, the type of transmitted modalities, the technology employed, security, billing issues and the anticipated future of teleradiology were addressed. One hundred and two (22.67%) of 450 radiologists responded to the survey. Of the total, 41.2% (42) were teleradiology users, 35.3% (36) planned to use teleradiology in the near future and 24.5% (25) did not use or plan to use teleradiology. The mean number of examinations transmitted per month was 198 (range 1-2,000) and the mean distance was 33 km (range 1,250 km). An emergency service was considered the most important purpose (mean score 6.90; minimum 1, maximum 10) for the use of teleradiology, followed by image distribution (mean 6.74) and expert consultation (mean 6.61). The most commonly transmitted modality was computed tomography (mean 8.80), followed by conventional X-rays (8.40) and magnetic resonance imaging (8.32). The most commonly transmitted format was Digital Imaging and Communications in Medicine (DICOM) (66.7%), followed by bitmap/Joint Photographic Experts Group (jpg) (38.1%), using the DICOM send/receive protocol (52.4%), followed by the hypertext transfer protocol (26.2%) and e-mail (21.4%). For security a secure connection (54.8%) followed by encryption (14.3%) and anonymization (9.5%) was used. For the future, image distribution was rated the most important aspect of teleradiology (7.88), followed by emergency (7.22) and expert consultation (6.53). Development of legal regulations is considered most important (8.17), followed by data security guidelines (8.15). Most radiologists believe that insurance companies should pay for the costs of teleradiology (37

    Efforts were exerted to develop intermetallic compounds and advanced C/C (carbon/carbon) composite materials usable under extreme environments such as high temperatures. In relation with advanced composite materials, especially with projects for developing composite materials using oil as raw material, a survey was conducted of the three fields of (1) summarization of activities conducted up to fiscal 1991, (2) contents of associated aerospace projects, and (3) oil based composite material technology. In Field (1), past achievements are summarized. In Field (2), aerospace projects under way across the world are broken down by airframe and engine, and are reviewed from the viewpoint of needs for materials. In Field (3), the present and future of heat resisting thermosetting composite materials, thermoplastic composite materials, and C/C composites are discussed. Characteristics such materials are supposed to finally assume and tasks to discharge for technical development are also taken up. (NEDO)

    Although African-Americans (Blacks) smoke fewer cigarettes per day than European-Americans (Whites), there is ample evidence that Blacks are more susceptible to smoking-related health consequences. A variety of behavioural, social and biological factors have been linked to this increased risk. There has been little research, however, on racial differences in smoking-related knowledge and perceived risk of lung cancer. The primary goal of the current study was to evaluate beliefs and knowledge that contribute to race disparities in lung cancer risk among current smokers. Data from two separate nationally representative surveys (the Health Information National Trends surveys 2003 and 2005) were analysed. Logistic and hierarchical regressions were conducted; gender, age, education level, annual household income and amount of smoking were included as covariates. In both studies, Black smokers were significantly more likely to endorse inaccurate statements than were White smokers, and did not estimate their lung cancer risk to be significantly higher than Whites. Results highlight an important racial disparity in public health knowledge among current smokers.

    The purpose of this study was to describe common approaches used by nursing researchers to test mediation models and evaluate them within the context of current methodological advances. MEDLINE was used to locate studies testing a mediation model and published from 2004 to 2015 in nursing journals. Design (experimental/correlation, cross-sectional/longitudinal, model complexity) and analysis (method, inclusion of test of mediated effect, violations/discussion of assumptions, sample size/power) characteristics were coded for 456 studies. General trends were identified using descriptive statistics. Consistent with findings of reviews in other disciplines, evidence was found that nursing researchers may not be aware of the strong assumptions and serious limitations of their analyses. Suggestions for strengthening the rigor of such studies and an overview of current methods for testing more complex models, including longitudinal mediation processes, are presented.

  7. Trends in Research on Writing as a Learning Activity

    Full Text Available This article discusses five trends in research on writing as a learning activity. Firstly, earlier decades were marked by conflicting views about the effects of writing on learning; in the past decade, the use of meta-analysis has shown that the effects of writing on learning are reliable, and that several variables mediate and moderate these effects. Secondly, in earlier decades, it was thought that text as a medium inherently elicited thinking and learning. Research during the past decade has indicated that writing to learn is a self-regulated activity, dependent on the goals and strategies of the writer. Thirdly, the Writing Across the Curriculum (WAC movement emphasized domain-general approaches to WTL. Much recent research is consistent with the Writing in the Disciplines (WID movement, incorporating genres that embody forms of reasoning specific to a given discipline. Fourthly, WTL as a classroom practice was always partially social, but the theoretical conceptualization of it was largely individual. During the past two decades, WTL has broadened to include theories and research that integrate social and psychological processes. Fifthly, WTL research has traditionally focused on epistemic learning in schools; more recently, it has been extended to include reflective learning in the professions and additional kinds of outcomes.

    To reduce Europe`s greenhouse gas emission CO{sub 2} it is a challenging task utilising biomass fuels as there are wood or wood residues from the forest industry. The utilisation can be done either in commercially operated medium (> 50 kWth) or full scale (> 1 MWth) decentralised heat and power stations or in small scale (< 50 kWth) domestic heating systems. In small scale heating systems untreated wood logs, wood briquette or wood pellets and in few cases wood chips are used. The present market in Germany is focused on the use of wood logs. Presently, the use of wood pellets in small scale automatically operated boilers < 15 kW especially for low energy houses is discussed more and more. Since 1980 the installation of new wood fired small scale domestic heating systems reached a significant size due to the interest of the customers to have a alternative inhouse heating system and to increase the living comfort. In 1994 the amount of sold small scale heaters in Germany were in total about 133.258 units. The thermal power of in 1994 sold units is estimated of about 1350 MW which is a significant size in total with regard to domestic heating purposes. Since few years there is a clear market trend in Germany towards the installation of open fire stoves. Due to this trend in Germany and the design characteristic of open fire stoves using huge glass doors of glass windows it is very difficult to achieve a further reduction of emissions like CO and unburned volatile hydrocarbons (VOC). In the text the requirements for modern small scale wood fired stoves in Germany as well as the actual stage and trend of research and development (R and D) are discussed 4 refs.

    To assess resources available to junior faculty in US academic radiology departments for research mentorship and funding opportunities and to determine if certain resources are more common in successful programs. An anonymous survey covering scientific environment and research mentorship and was sent to vice-chairs of research of radiology departments. Results were evaluated to identify practices of research programs with respect to mentorship, resources, and opportunities. Academy of Radiology Research's 2012 National Institutes of Health (NIH) grants and awards list was used to determine if environment and practices correlate with funding. There was a 51% response rate. A greater fraction of clinical faculty gets promoted from assistant to associate professor than research faculty. Research faculty overall submits more funding applications. Most programs support start-up costs and K-awards. Over half of the departments have a vice-chair for faculty development, and most have formal mentorship programs. Faculty members are expected to teach, engage in service, publish, and apply for and get research funding within 3 years of hire. Top-tier programs as judged by NIH awards have a combination of MDs who devote >50% effort to research and PhD faculty. Key factors holding back both clinical and research junior faculty development were motivation, resources, and time, although programs reported high availability of resources and support at the department level. Better marketing of resources for junior faculty, effort devoted to mentoring clinical faculty in research, and explicit milestones/expectations for achievement could enhance junior faculty success, promote interest in the clinician–scientist career path for radiologists, and lead to greater research success.

    There have been a number of debates in the field of nursing ethics. Researchers have focused on various aspects of nursing ethics, such as professional ethics, professional, nursing and ethical values. Within this research, a variety of literature reviews have been conducted, but to the best of our knowledge, bibliometric mapping has not yet been used. This article aims to analyse the production of literature within nursing ethics research. In order to examine publishing patterns, we focused on publishing dynamics, prolific research entities and the most-cited articles. We additionally visualised the content of the literature using a novel mixed-method approach, combining bibliometric analysis and mapping with thematic analysis. Ethical considerations: In our study, ethical review was not required. A total of 1416 information sources were found in the Scopus database. Overall, literature production has increased; however, in recent years, the quantity of published material has begun to decrease. The most prolific countries are the United States, the United Kingdom and Canada, and the most prolific source titles are Nursing Ethics, Journal of Advanced Nursing and Nursing Times. Lately, research in the field of nursing ethics has been focused more on life care (providing for the basic needs of older residents), moral distress and community nursing. The dynamics of research literature production showed an exponential rise in the number of published information sources - a rise which started in the period between 1974 and 1998. Since that period, the trend has stabilised, which might indicate that nursing ethics research is starting a transition to a mature phase. The innovative use of bibliometric analysis and mapping, together with thematic analysis, is a useful tool for analysis of research production in the field of nursing ethics. The results presented can be an excellent starting point for literature reviews and more exhaustive data, information and knowledge

    The aim of this study is to identify the trends in practice pattern among current ophthalmology residents in Saudi Arabia. Ophthalmology residents in Saudi Arabia responded anonymously to a written survey between November 2007 and February 2008. The survey contained questions on demographic information, medical education, residency training, career goals and factors influencing their career choice. The data were categorized by gender. The influence of gender on outcome was assessed in a univariate fashion using the Chi-square or Fisher exact test when appropriate. A P-value of 0.05 or less was considered statistically significant for all analyses. A total of 68 out of 85 residents (80%) responded to the survey. Over one-half of the residents preferred to pursue a fellowship within Saudi Arabia (53%), while others (25%) planned to train in North America. The majority of respondents wished to practice in an urban setting (63%). Anterior segment was the most desired subspecialty, while general ophthalmology and glaucoma were not a popular choice. Most residents were interested in refractive surgery (77%) and research (75%). The main factor influencing the decision to pursue ophthalmology was the ability to combine medicine and surgery (97%), while a positive elective experience was also an important factor, particularly for female respondents (91% vs. 57%; P < 0.001). Concerted efforts are required to encourage adoption to ophthalmic practice in public institutions rather than in private practice. In addition training in underrepresented subspecilaties should be encouraged to ensure adequate ophthalmic care for all citizens of Saudi Arabia.

    This paper describes surveys on trends in overseas technologies in development plans for geothermal water utilizing power plants. In heat cycles, the binary and two-stage flash cycles were analyzed by using a generalized equation of state, and theses on optimizing working fluid properties and cycle conditions with maximum thermal efficiency were described. Theses that were described include those for criteria to select working fluids and thermal power cycles against the binary cycle using a heat source at 104 to 204 degree C. The binary cycle working fluid was found better in mixed systems than in pure systems as seen from process and economic performance. The paper introduces a heat conductivity experimenting device and data required for designing a heat exchanger. It also describes the Heber geothermal experimental plant to demonstrate reasonability of assumed working media. A fluidized bed type and a shell tube type were applied to heat exchangers at the Raft River 50 MW geothermal power plant for comparison and discussion. Fouling factor was also estimated. A discussion was given on fluidity distribution of a fluidized bed heat exchanger. Design of a heat discharge system is important for geothermal power generation because heat source temperatures are so low that more than 85% of heat that has been taken in is discharged. The paper also describes turbines and other facilities. (NEDO)

    Livestock are one of the largest users of land. The use vast areas of rangelands and pasturelands and use a third of the global cropland for feed production. The demand of rlivestock products is growing at an accelerated rate due to large increases in income and urbanisation, primarily in the developing world. While most expansion is occuring the the poultry and pork sectors, ruminant meat and milk are also increasing significantly. There is concern as to how to manage the environmental footprints of these very dynamic systems. At the same, time, significnat opportunities to intensify land use in the the livestock sector exist, primarily in grasslands. This paper gives an overview of the trends in land use in the global livestock sector, assess the status of supply and demand of livestock products and how these might be met in the future and cocludes by proposing a research agenda with key areas that merit more attention from biophysical, social and economic scientists.

    The field of music therapy is growing worldwide. While there is a wealth of country-specific information available, only a few have databased workforce censuses. Currently, little to no descriptive data exists about the global development of the profession. The purpose of this study was to obtain descriptive data about current demographics, practice status, and clinical trends to inform worldwide advocacy efforts, training needs, and the sustainable development of the field. Music therapists (N = 2,495) who were professional members of organizations affiliated with the World Federation of Music Therapy (WFMT) served as a sample for this international cross-sectional survey study. A 30-item online questionnaire was designed, pilot tested by key partners, and translated into seven languages. Researchers and key partners distributed the online survey through e-mail invitations and social media announcements. Professional music therapists worldwide are well-educated, mature professionals with adequate work experience, who are confident in providing high-quality services primarily in mental health, school, and geriatric settings. Due to ongoing challenges related to recognition and government regulation of the field as an evidence-based and well-funded healthcare profession, most individuals work part-time music therapy jobs and feel underpaid. Yet, many music therapists have a positive outlook on the field's future. Continued research and advocacy efforts, as well as collaborations with lobbyists, business consultants, and credentialing/licensure experts to develop progressive strategies, will be crucial for global development and sustainability of the field. © the American Music Therapy Association 2017.

    2015-07-01

    Minimising the use of animals in experiments is universally recognised by scientists, governments and advocates as an ethical cornerstone of research. Yet, despite growing public opposition to animal experimentation, mounting evidence that animal studies often do not translate to humans, and the development of new research technologies, a number of countries have reported increased animal use in recent years. In the USA--one of the world's largest users of animals in experiments--a lack of published data on the species most commonly used in laboratories (eg, mice, rats and fish) has prevented such assessments. The current study aimed to fill this gap by analysing the use of all vertebrate animals by the top institutional recipients of National Institutes of Health research funds over a 15-year period. These data show a statistically significant 72.7% increase in the use of animals at these US facilities during this time period-driven primarily by increases in the use of mice. Our results highlight a need for greater efforts to reduce animal use. We discuss technical, institutional, sociological and psychological explanations for this trend.

    The objectives of this study were to trace and describe research patterns in singing voice, to compare the amount of published research over time, to identify journals that published most papers on "singing voice," and to establish the most frequent research topics. The study uses qualitative and quantitative approaches through descriptive statistics, text mining, and clustering. The authors conducted a search to identify scientific papers. The titles and abstracts were analyzed regarding word frequency and relations between them, through hierarchical cluster analysis and co-occurrence networks. The frequency of journals was calculated, as well as the amount of papers across time. Since 1949, 754 papers were published and an increase was noticed. Even though 162 journals were identified by the authors, the Journal of Voice holds the majority of papers, in every analyzed period. An evolution of studied topics is described. Up to 2010, the main theme was professional singers, especially classical and opera interpreters. Since then, voice quality and the effects of training gathered more attention. The growing interest in singing has been conspicuous since the first indexed paper. However, it has been slightly slowing down. Until 2010, great importance was given to the voice quality of singers and their occupational demands. Acoustic analysis was widely used to study the effects of training. Since 2010, the concern with functionality is increasing, rather than the organic voice structures. Musical perception studies have been a trend, as well as the use of electroglottography.

    The price of tobacco products in relation to the income of tobacco users-affordability-is recognised as a key determinant of tobacco use behaviour. The effectiveness of a price increase as a deterrent to tobacco use depends on how much price increases in relation to the income of the potential users. The aim of this paper is to examine the distribution of and trends in the affordability of tobacco products in Bangladesh. Using four waves of International Tobacco Control Survey data on Bangladesh, this study measures affordability of tobacco products at the individual level as the ratio of self-reported price and self-reported income. The trends in affordability by brand categories of cigarettes and of bidi and smokeless tobacco are estimated using multivariate linear regression analysis. Despite significant increase in price, the affordability of cigarettes increased between 2009 and 2014-2015 due to income growth outpacing price increase. The increase was disproportionately larger for more expensive brands. The affordability of bidis increased over this period as well. The affordability of smokeless tobacco products remained unchanged between 2011-2012 and 2014-2015. The tax increases that were implemented during 2009-2015 were not enough to increase tobacco product prices sufficiently to outweigh the effect of income growth, and to reduce tobacco consumption. The findings from this research inform policymakers that in countries experiencing rapid economic growth, significant tax increases are needed to counteract the effect of income growth, in order for the tax increases to be effective in reducing tobacco use. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    To provide an overview of health services research related to health technology assessment (HTA) and to identify research priorities from a European perspective. Several methods were used: systematic review of articles indexed with the MeSH term 'technology assessment' in PubMed from February 1999-2009; online survey among experts; and conference workshop discussions. Research activity in HTA varies considerably across Europe. The research was categorised into six areas: (1) the breadth of analysis in HTA (such as economic, organizational and social aspects); (2) HTA products developed to meet the needs of policy-makers (such as horizon scanning, mini-HTA, and core HTA); (3) handling life-cycle perspectives in relation to technologies; (4) topics that challenge existing methods and for which HTA should be developed to address the themes more comprehensively (such as public health interventions and organizational interventions); (5) development of HTA capacity and programmes; and (6) links between policy and HTA. An online survey showed that the three areas that were given priority were the relationship between HTA and policy-making (71%), the impact of HTA (62%) and incorporating patient aspects in HTA (50%). Policy-makers highlighted HTA and innovation processes as their main research priority (42%). Areas that the systematic review identified as future priorities include issues within the six existing research areas such as disinvestment, developing evidence for new technologies, assessing the wider effects of technology use, and determining how HTA affects decision-making. In addition, relative effectiveness and individualized treatments are areas of growing interest. The research priorities identified are important for obtaining high quality and cost-effective health care in Europe. Managing the introduction, use and phasing out of technologies challenges health services throughout Europe, and these processes need to be improved to successfully manage future

    The assessment of trends in climatology and hydrology still is a matter of debate. Capturing typical properties of time series, like trends, is highly relevant for the discussion of potential impacts of global warming or flood occurrences. It provides indicators for the separation of anthropogenic signals and natural forcing factors by distinguishing between deterministic trends and stochastic variability. In this contribution river run-off data from gauges in Southern Germany are analysed regarding their trend behaviour by combining a deterministic trend component and a stochastic model part in a semi-parametric approach. In this way the trade-off between trend and autocorrelation structure can be considered explicitly. A test for a significant trend is introduced via three steps: First, a stochastic fractional ARIMA model, which is able to reproduce short-term as well as long-term correlations, is fitted to the empirical data. In a second step, wavelet analysis is used to separate the variability of small and large time-scales assuming that the trend component is part of the latter. Finally, a comparison of the overall variability to that restricted to small scales results in a test for a trend. The extraction of the large-scale behaviour by wavelet analysis provides a clue concerning the shape of the trend.

    This paper examines the development of ergonomics in Taiwan by analysing 1404 scientific articles published by 113 permanent members of the Ergonomics Society of Taiwan (EST). Each article was classified by key words and abstract content. Each article was also coded by period of publication (1971-1992 (first period), 1993-1997 (second period), 1998-2002 (third period), 2003-2007 (fourth period), and 2008-2012 (fifth period), and against 13 topic categories. The results show that rate of publication has increased by approximately 100 articles every five years since 1993.The most popular topic was ergonomics assessment and analysis techniques in the first period, force exertion-related research in the second period, product design and evaluation in the third period, occupational safety and health in the fourth period and human-computer interface in the fifth period. Each of these is highly relevant to current contemporary issues around the world. Finally, potential areas for future ergonomics research in Taiwan are discussed. This study investigates the trends in academic papers published by members of the EST. Over time, topics have shifted from ergonomics evaluation methods to occupational safety and health, and human–computer interaction. The findings should be considered as important references for planning the future of ergonomics in Taiwan.

    Published drug safety data has evolved in the past decade due to scientific and technological advances in the relevant research fields. Considering that a vast amount of scientific literature has been published in this area, it is not easy to identify the key information. Topic modeling has emerged as a powerful tool to extract meaningful information from a large volume of unstructured texts. Areas covered: We analyzed the titles and abstracts of 4347 articles in four journals dedicated to drug safety from 2007 to 2016. We applied Latent Dirichlet allocation (LDA) model to extract 50 main topics, and conducted trend analysis to explore the temporal popularity of these topics over years. Expert Opinion/Commentary: We found that 'benefit-risk assessment and communication', 'diabetes' and 'biologic therapy for autoimmune diseases' are the top 3 most published topics. The topics relevant to the use of electronic health records/observational data for safety surveillance are becoming increasingly popular over time. Meanwhile, there is a slight decrease in research on signal detection based on spontaneous reporting, although spontaneous reporting still plays an important role in benefit-risk assessment. The topics related to medical conditions and treatment showed highly dynamic patterns over time.

The aim of this study was to describe 1 the number of clinical trials submitted to the Brazilian Health Surveillance Agency (Agência Nacional de Vigilância Sanitária, Anvisa from 2007 to 2012 and the number of human-subject research projects approved by research ethics committees (RECs and the National Research Ethics Committee (Comissão Nacional de Ética em Pesquisa, CONEP in Brazil from 2007 to 2011 and 2 the diseases most frequently studied in Brazilian states in clinical trials approved in the country from 2009 to 2012, based on information from an Anvisa databank. Two databases were used: 1 the National Information System on Research Ethics Involving Human Beings (Sistema Nacional de Informação Sobre Ética em Pesquisa envolvendo Seres Humanos, SISNEP and 2 Anvisa's Clinical Research Control System (Sistema de Controle de Pesquisa Clínica, SCPC. Data from the SCPC indicated an increase of 32.7% in the number of clinical trials submitted to Anvisa, and data from the SISNEP showed an increase of 69.9% in those approved by RECs and CONEP (from 18 160 in 2007 to 30 860 in 2011. Type 2 diabetes (26.0% and breast cancer (20.5%-related to the main causes of mortality in Brazil-were the two most frequently studied diseases. The so-called “neglected diseases,” such as dengue fever, were among the least studied diseases in approved clinical trials, despite their significant impact on social, economic, and health indicators in Brazil. Overall, the data indicated 1 a clear trend toward more research involving human beings in Brazil, 2 good correspondence between diseases most studied in clinical trials approved by Anvisa and the main causes of death in Brazil, and 3 a low level of attention to neglected diseases, an issue that should be considered in setting future research priorities, given their socioeconomic and health effects.

    The international community has recognized the serious threat posed by nuclear and other radioactive material out of regulatory control. To address these concerns, the Office of Nuclear Security of the international Atomic Energy Agency (IAEA) is developing, inter alia, guidance for nuclear forensics to assist Member States. According to the IAEA Incident and Trafficking Database (ITDB) of the IAEA to record the illegal trade and trafficking incidents of nuclear material or other radioactive material, incidents of 2331 have been reported in 1993 to 2012. These incidents mean that we are not safe for nuclear material. In order to solve the case generated by the illicit trafficking of nuclear material and the efficient management of nuclear material, the study of nuclear forensics is very important. In this study, we investigated the analytical techniques and the current status of nuclear forensics research. In this study, we investigated the current status of research of nuclear forensics, procedures for analysis and nuclear forensics analysis technique. A result of the study, we have been found that the major institutes and laboratory actively research on analysis technique and nuclear forensics. However, research on nuclear forensics is still in early stage, ROK is necessary preliminary survey of analysis technique and foundation of physical, chemical, and morphology characteristics of nuclear materials

    Despite increasing interest in smartphone apps as a platform for delivery of tobacco cessation interventions, no previous studies have evaluated the prevalence and characteristics of smokers who can access smartphone-delivered interventions. To guide treatment development in this new platform and to evaluate disparities in access to smartphone-delivered interventions, we examined associations of smartphone ownership with demographics, tobacco use and thoughts about quitting, other health behaviors, physical and mental health, health care access, and Internet and technology utilization using a nationally representative sample of US adult smokers. Data were from the National Cancer Institute's 2014 Health Information National Trends Survey 4 (HINTS 4), Cycle 4. This mailed survey targeted noninstitutionalized individuals aged 18 years or older using two-stage stratified random sampling. For this analysis, we restricted the sample to current smokers with complete data on smartphone ownership (n=479). Nearly two-thirds (weighted percent=63.8%, 248/479) of smokers reported owning a smartphone. Those who were younger (P<.001), employed (P=.002), never married (P=.002), and had higher education (P=.002) and income (P<.001) had the highest rates of ownership. Smartphone owners did not differ from nonowners on frequency of smoking, recent quit attempts, or future plans to quit smoking, although they reported greater belief in the benefits of quitting (P=.04). Despite being equally likely to be overweight or obese, smartphone owners reported greater fruit and vegetable consumption (P=.03) and were more likely to report past-year efforts to increase exercise (P=.001) and to lose weight (P=.02). No differences in health care access and utilization were found. Smartphone owners reported better physical and mental health in several domains and higher access to and utilization of technology and the Internet, including for health reasons.

    To develop statistical tests for comparing trend curves of study outcomes between two socio-demographic strata across consecutive time points, and compare statistical power of the proposed tests under different trend curves data, three statistical tests were proposed. For large sample size with independent normal assumption among strata and across consecutive time points, the Z and Chi-square test statistics were developed, which are functions of outcome estimates and the standard errors at each of the study time points for the two strata. For small sample size with independent normal assumption, the F-test statistic was generated, which is a function of sample size of the two strata and estimated parameters across study period. If two trend curves are approximately parallel, the power of Z-test is consistently higher than that of both Chi-square and F-test. If two trend curves cross at low interaction, the power of Z-test is higher than or equal to the power of both Chi-square and F-test; however, at high interaction, the powers of Chi-square and F-test are higher than that of Z-test. The measurement of interaction of two trend curves was defined. These tests were applied to the comparison of trend curves of vaccination coverage estimates of standard vaccine series with National Immunization Survey (NIS) 2000-2007 data.

  20. Networked event-triggered control: an introduction and research trends

    A physical system can be studied as either continuous time or discrete-time system depending upon the control objectives. Discrete-time control systems can be further classified into two categories based on the sampling: (1) time-triggered control systems and (2) event-triggered control systems. Time-triggered systems sample states and calculate controls at every sampling instant in a periodic fashion, even in cases when states and calculated control do not change much. This indicates unnecessary and useless data transmission and computation efforts of a time-triggered system, thus inefficiency. For networked systems, the transmission of measurement and control signals, thus, cause unnecessary network traffic. Event-triggered systems, on the other hand, have potential to reduce the communication burden in addition to reducing the computation of control signals. This paper provides an up-to-date survey on the event-triggered methods for control systems and highlights the potential research directions.

    Current trends and issues in the development of alternatives to the use of animals in biomedical experimentation are discussed in this position paper. Eight topics are considered and include refinement of acute toxicity assays; eye corrosion/irritation alternatives; skin corrosion/irritation alternatives; contact sensitization alternatives; developmental/reproductive testing alternatives; genetic engineering (transgenic) assays; toxicogenomics; and validation of alternative methods. The discussion of refinement of acute toxicity assays is focused primarily on developments with regard to reduction of the number of animals used in the LD(50) assay. However, the substitution of humane endpoints such as clinical signs of toxicity for lethality in these assays is also evaluated. Alternative assays for eye corrosion/irritation as well as those for skin corrosion/irritation are described with particular attention paid to the outcomes, both successful and unsuccessful, of several validation efforts. Alternative assays for contact sensitization and developmental/reproductive toxicity are presented as examples of methods designed for the examination of interactions between toxins and somewhat more complex physiological systems. Moreover, genetic engineering and toxicogenomics are discussed with an eye toward the future of biological experimentation in general. The implications of gene manipulation for research animals, specifically, are also examined. Finally, validation methods are investigated as to their effectiveness, or lack thereof, and suggestions for their standardization and improvement, as well as implementation are reviewed.

    Asbestos is a well-known cause of cancer and respiratory diseases. The aim of the current study was to investigate the scientific production in asbestos research evaluating temporal trend, geographic distribution, impact factor (IF) of published literature, and taking into account socioeconomic variables. The PubMed database was searched starting from 1970. Publication numbers and IF were evaluated as absolute values and after standardization by population and gross domestic product (GDP). Six thousand nine hundred seven articles related to asbestos were retrieved. Publications grew steeply in the 1970s, leveled off in the 1980s, decreased in the 1990s, and then increased again. Mesothelioma, lung neoplasms, and occupational diseases are the most commonly used keywords. In the period of 1988-2011, 4220 citations were retrieved, 3187 of whom had an impact factor. The US, Italy, and the UK were the most productive countries. European countries published about 20 % more asbestos-related articles than the US, although the latter reached a higher mean IF, ranking second after Australia. When the national scientific production (sum of IF) was compared taking into account socioeconomic variables, Australia and Scandinavian countries performed very well, opposite to all main asbestos producers like Russia, China, and Brazil (except for Canada). The American Journal of Industrial Medicine and the Italian La Medicina del Lavoro published the highest numbers of articles. This study provides the first bibliometric analysis of scientific production in asbestos research. Interest appears to be higher in selected countries, with strong national features, and is growing again in the new millennium.

    ENGLISH ABSTRACT: Industrial engineering is an engineering discipline which, because of its multi-disciplinary nature, has played an important role in the development and optimization of different systems at macro and micro levels. In this paper, the results of a research to study the position and trend of Industrial Engineering research in recent years are described. The data from a sample of 7 114 IE-related articles from international journals during the last 27 years were used for the analysis. The results showed that the development of IE in many countries has a strong correlation with their industrial and economic development. However, IE research topics are spreading in other management and engineering departments and so there is a need to redefine the discipline and its specific areas of interest. According to the prediction made using time series analysis, the most favorite fields of IE research in future will be on subjects related to information technology, intelligent systems, optimization, quality, and supply chain management.

    This study consisted of two parts. Part 1 was a survey of US program directors, and Part 2 reports on the survey findings distributed to the deans of US dental schools. Both surveys evaluated observations of trends in prosthodontic education. The first survey (2005) of program directors and deans was published in 2007. This second survey was conducted in 2009. The 2009 survey provided 10-year data on trends in prosthodontics as reported by program directors. A national e-mail survey of 46 program directors was used to collect enrollment data for years 1 to 3 of prosthodontics training for US and international dental school graduates, the total number of applicants and applications considered, and the trends over time of applicants to prosthodontics for US dental school graduates and for international graduates. In addition, the program directors were asked to rank 13 key factors that may have contributed to any changes in the prosthodontic applicant pool. Program directors were also asked for information on student financial incentives and whether their programs were state or federally funded, and whether their sponsoring institution was a dental school. Of the 46 program directors, 40 responded, for an 87% response rate. Respondents reported that 66% of their enrollees were graduates of US dental schools. Between 2000 and 2009 the applicant pool in prosthodontics nearly doubled, with 50% of the program directors reporting an increase in US-trained applicants, 42.5% reporting no change, and only 7.5% reporting a decrease. Using the Spearman correlation for the 10-year survey, there was a positive, statistically significant correlation that society's demand for a higher level of training and credentialing and interest in prosthodontics among dental students contributed to an increase in the number of US dental graduates applying to prosthodontic programs. Only four programs offered no financial packages to offset tuition. The remaining 36 respondents reported some

    Full Text Available Despite allocating huge budgets to civil engineering projects, detailed planning, and employing human resources, project managers still face time, cost, and quality constraints. Most of these challenges are due to a lack of integration of different project phases and the limitations of the presence of construction and maintenance contractors in the initial stages of the project. Considering the benefits of applying constructability, operability, and maintainability (COM concepts, many problems caused by lack of coordination, or duplications and weakness in management, and also time and extra costs due to lack of presence of construction and maintenance contractors in the early stages of the project are resolvable. In this regard, various studies have investigated the benefits of applying these concepts; however, there has been no comprehensive analysis of the benefits of COM. As a result of focus on the benefits of implementation of these concepts and evaluating the effect of each of these strategies and benefits, from different perspectives during various time periods, managers can increase project efficiency and productivity, and improve their performance, through using concepts and strategies of their implementation. This research aims to evaluate the trend of studies on the benefits of implementing constructability, operability, and maintainability in the construction industry. For that, the in-depth literature review method is applied. For qualitative analysis of the obtained information, descriptive analysis has been used. Then, the data was coded, and classified using Excel Software for quantitative data analysis. Finally, the charts presented were evaluated according to the classified fields of study. The necessity of performing such a study is significant because of the fact that a large share of a project’s problems, such as lack of plans’ integration and weakness of administrative system, and increasing time and cost, are due to

  9. Reflections upon the trends of education and research in small animal reproduction in Europe.

    2004-01-01

    An open questionnaire-based survey was performed among 86 institutions of veterinary education in 32 European countries: 15 within the European Union (EU) and 17 outside the EU, in Central and Eastern Europe and the European Free Trade Association (EFTA). The survey aimed to provide a view of the general status of education and research in small animal reproduction (SAR) in Europe. It further aimed to disclose whether ongoing trends in organization (e.g., from the classical animal reproduction discipline orientation [DO] toward a species-oriented [SO] organization) among veterinary colleges responsible for undergraduate education and research in SAR have affected the provision of clinical services, continuing professional development (CPD), specialization, post-graduate education, and research. Response rates reached 80% among EU institutions and 48.4% in other countries (overall response rate = 68.6%). A clear, significant majority of institutions (> 60%) were DO, with a well-defined comparative subject in the veterinary curriculum. No differences were reported for either orientation in their ability to provide undergraduate education or clinical services in SAR. However, more DO institutions reported active research in SAR than their SO counterparts. Similar (and stronger) differences were seen for post-graduate education, CPD, and participation in specialization programs (national or European). Finally, more DO than SO institutions provided assisted reproductive technologies (ARTs), such as AI with frozen semen, to customers. The analysis of the data emanating from the respondents' perceptions, supports the advantages of the more classical, DO-based approach. The results highlight the need for caution when institutions abandon the comparative benefits of the classical DO animal reproduction subject for a SO approach, which tends to prioritize clinical specialized service rather than research and research education. In the author's opinion, in the absence of the

    To describe data from the National Health Interview Survey (NHIS), both the annual core survey and periodic occupational health supplements (OHSs), available for examining national trends in worker health. The NHIS is an annual in-person household survey with a cross-sectional multistage clustered sample design to produce nationally representative health data. The 2010 NHIS included an OHS. Prevalence rates of various health conditions and health behaviors among workers based on multiple years of NHIS core data are available. In addition, the 2010 NHIS-OHS data provide prevalence rates of selected health conditions, work organization factors, and occupational exposures among US workers by industry and occupation. The publicly available NHIS data can be used to identify areas of concern for various industries and for benchmarking data from specific worker groups against national averages.

    Polyhydroxyalkanoates are bio-based, biodegradable naturally occurring polymers produced by a wide range of organisms, from bacteria to higher mammals. The properties and biocompatibility of PHA make it possible for a wide spectrum of applications. In this context, we analyze the potential applications of PHA in biomedical science by exploring the global trend through the patent survey. The survey suggests that PHA is an attractive candidate in such a way that their applications are widely distributed in the medical industry, drug delivery system, dental material, tissue engineering, packaging material as well as other useful products. In our present study, we explored patents associated with various biomedical applications of polyhydroxyalkanoates. Patent databases of European Patent Office, United States Patent and Trademark Office and World Intellectual Property Organization were mined. We developed an intensive exploration approach to eliminate overlapping patents and sort out significant patents. We demarcated the keywords and search criterions and established search patterns for the database request. We retrieved documents within the recent 6 years, 2010 to 2016 and sort out the collected data stepwise to gather the most appropriate documents in patent families for further scrutiny. By this approach, we retrieved 23,368 patent documents from all the three databases and the patent titles were further analyzed for the relevance of polyhydroxyalkanoates in biomedical applications. This ensued in the documentation of approximately 226 significant patents associated with biomedical applications of polyhydroxyalkanoates and the information was classified into six major groups. Polyhydroxyalkanoates has been patented in such a way that their applications are widely distributed in the medical industry, drug delivery system, dental material, tissue engineering, packaging material as well as other useful products. There are many avenues through which PHA & PHB could be

    For survey of the industrial competitive force, it is important to arrange the environment where the continuous and spontaneous technical innovation is generated. To recognize the present situation, the patent information relating to technical innovation, etc. were collected, indices of the number of patent, degree of the reference and scientific link in Japan, the U.S., and Europe were taken out by technology field to analyze the patent trend in the past 10 years. By technology field, the U.S. is superior in a lot of fields. Japan is at top rank in office supplies and camera fields, made strenuous efforts in automobile and semiconductor/electronic fields, but is behind others in medicine, biotechnology and aerospace fields. Concerning the number of patent registration in the U.S., Japan is superior to the U.S. in automobile/electric equipment/metal industries. Europe is superior in food and engineering fields. The U.S. is superior in aerospace industry and biotechnology fields. The U.S. is featured by a large number of patent applications by universities and government organizations. (NEDO)

    This paper presents a quantitative analysis of research trends in the fields of plasma physics and nuclear fusion. This analysis is based on information retrieval from available data bases such as INSPEC tapes. The results indicate that plasma physics research is now in the maturation phase of its life cycle, and that nuclear fusion research is in its growth phase. This paper indicates that there is a correlation between the number of accumulated papers in the fields of plasma physics and nuclear fusion and the experimentally attained values of the plasma ignition parameter ntT. Using this correlation ''research effort curve'', we forecast that the scientific feasibility of controlled fusion using magnetic confinement systems will be proved around 1983. (author)

  20. Gender in clinical neuropsychology: practice survey trends and comparisons outside the specialty.

    Sweet, Jerry J; Lee, Catherine; Guidotti Breting, Leslie M; Benson, Laura M

    2018-02-01

    This paper describes gender-related trends within clinical neuropsychology, based primarily on recurrent practice surveys within the specialty and, to a lesser extent, job-related information from medical specialties and the general U.S. labor market. Chronological and cross-sectional analyses of professional practice survey data from 2005, 2010, and 2015 relevant to gender. As is common with survey data, descriptive analysis and independent samples t-tests were conducted. Longitudinal data allowed for examination of gender trends, as well as observations of change and stability of factors associated with gender, over time. Women have become dominant in number in clinical neuropsychology, and also comprise a vast majority of practitioners entering the specialty. Gender differences are noted in professional identity, work status, work settings, types of career satisfaction, and retirement expectations. Women are more likely to identify work environment and personal/family obstacles to aspects of career satisfaction. A gender pay gap was found at all time points and is not narrowing. As is true nationally, multiple factors appear related to the gender pay gap in clinical neuropsychology. Women in neuropsychology are now dominant in number, and their presence is strongly associated with specific practice patterns, such as greater institutional employment, less involvement in forensic practice, and strong involvement in pediatric practice, which may be maintaining the sizeable gender pay gap in neuropsychology. As the proportion of women neuropsychologists continues to increase, flexible work hours, and alternative means of remuneration may be needed to offset current disproportionate family-related responsibilities.

    This study aimed to determine trends in prevalence, awareness, and control of hypertension in Malaysia and to assess the relationship between socioeconomic determinants and prevalence of hypertension in Malaysia.The distribution of hypertension in Malaysia was assessed based on available data in 3 National Health and Morbidity Surveys (NHMSs) and 1 large scale non-NHMS during the period of 1996 to 2011. Summary statistics was used to characterize the included surveys. Differences in prevalence, awareness, and control of hypertension between any 2 surveys were expressed as ratios. To assess the independent associations between the predictors and the outcome variables, regression analyses were employed with prevalence of hypertension as an outcome variable.Overall, there was a rising trend in the prevalence of hypertension in adults ≥30 years: 32.9% (30%-35.8%) in 1996, 42.6% (37.5%-43.5%) in 2006, and 43.5% (40.4%-46.6%) in 2011. There were significant increase of 32% from 1996 to 2011 (P Malaysia improved from 1996 to 2006. A change in the control of hypertension was 13% higher in women than in men.The findings suggest that the magnitude of hypertension in Malaysia needs additional attention. Strengthening the screening for hypertension in primary health-care settings in the high-risk groups and frequent health promotion to the community to enhance individual awareness and commitment to healthy living would be of immense value.

    Objectives. We explored changes in sexual orientation question item completion in a large statewide health survey. Methods. We used 2003 to 2011 California Health Interview Survey data to investigate sexual orientation item nonresponse and sexual minority self-identification trends in a cross-sectional sample representing the noninstitutionalized California household population aged 18 to 70 years (n = 182 812 adults). Results. Asians, Hispanics, limited-English-proficient respondents, and those interviewed in non-English languages showed the greatest declines in sexual orientation item nonresponse. Asian women, regardless of English-proficiency status, had the highest odds of item nonresponse. Spanish interviews produced more nonresponse than English interviews and Asian-language interviews produced less nonresponse when we controlled for demographic factors and survey cycle. Sexual minority self-identification increased in concert with the item nonresponse decline. Conclusions. Sexual orientation nonresponse declines and the increase in sexual minority identification suggest greater acceptability of sexual orientation assessment in surveys. Item nonresponse rate convergence among races/ethnicities, language proficiency groups, and interview languages shows that sexual orientation can be measured in surveys of diverse populations.

    The Health Information National Trends Survey (HINTS) collects nationally representative data about the American's public use of health-related information. This survey is available in English and Spanish, but not in American Sign Language (ASL). Thus, the exclusion of ASL users from these national health information survey studies has led to a significant gap in knowledge of Internet usage for health information access in this underserved and understudied population. The objectives of this study are (1) to culturally adapt and linguistically translate the HINTS items to ASL (HINTS-ASL); and (2) to gather information about deaf people's health information seeking behaviors across technology-mediated platforms. We modified the standard procedures developed at the US National Center for Health Statistics Cognitive Survey Laboratory to culturally adapt and translate HINTS items to ASL. Cognitive interviews were conducted to assess clarity and delivery of these HINTS-ASL items. Final ASL video items were uploaded to a protected online survey website. The HINTS-ASL online survey has been administered to over 1350 deaf adults (ages 18 to 90 and up) who use ASL. Data collection is ongoing and includes deaf adult signers across the United States. Some items from HINTS item bank required cultural adaptation for use with deaf people who use accessible services or technology. A separate item bank for deaf-related experiences was created, reflecting deaf-specific technology such as sharing health-related ASL videos through social network sites and using video remote interpreting services in health settings. After data collection is complete, we will conduct a series of analyses on deaf people's health information seeking behaviors across technology-mediated platforms. HINTS-ASL is an accessible health information national trends survey, which includes a culturally appropriate set of items that are relevant to the experiences of deaf people who use ASL.

  8. Publication trends in aeolian research: An analysis of the Bibliography of Aeolian Research

    Stout, John E.; Warren, Andrew; Gill, Thomas E.

    2009-04-01

    An analysis of the Bibliography of Aeolian Research has provided information regarding publication trends in aeolian research. Results suggest that there has been a significant increase in the number of publications per year since the first aeolian-research publication appeared in 1646. Rates of publication have increased from only three publications in the 17th Century to nearly three publications per day in the 21st Century. The temporal distribution of publications follows a complex pattern that is influenced by many factors. In the 17th and 18th Centuries, publications appear as isolated clusters indicating limited interest in aeolian research and limited opportunities for individuals to contribute to scientific literature. With time, many new scientific societies are formed and many new scientific journals are established, opening new opportunities for scientists to contribute to scientific discourse. Landmark publications open up new research areas and define new directions for aeolian research. General advances in science and technology provide new techniques for sampling blowing sand and dust. In addition, clear signs exist that publication rates respond to major environmental and climatic events, especially large-scale disasters that focus attention on wind erosion and blowing dust. The Sirocco dust events of 1901-1903, the North American Dust Bowl of the1930s, and the recent sand and dust storm problems in China have all led to significant increases in the number of publications in aeolian research. Rates of publication are negatively influenced by major political and social upheavals, especially global conflicts such as World Wars I and II. Sudden shifts in government structure and support can also influence publication rates. A good example is the increased publication rates in China following the end of the Cultural Revolution, a trend that continues today.

  9. Deterioration trends of asphalt pavement friction and roughness from medium-term surveys on major Italian roads

    Full Text Available Deterioration models are the key factor for effective Pavement Management Systems, helping out road agencies to assess the actual pavement condition and forecast future performance of the asset. Among pavement condition characteristics, friction should be taken into account due to its important effect on user safety, while roughness could be used to express user comfort. The purpose of this study was to provide a reasonable case study for future improvements of Italian road management, even if the length of the analyzed highways was not intended to be representative of the overall Italian network.This research studied the friction trend (Side Force Coefficient depending on traffic levels (ESALs and pavement aging for Italian highways, combining the data with roughness and macrotexture. Surface characteristics were monitored during a seven-year time span. A selection of different road sections with homogeneous traffic levels, similar environmental conditions and surface material was performed and high-speed/high-quality road surveys were used for distress data collection. Pavement deterioration models for Italian road sectors were developed at project level, as starting point to advance pavement management practices in Italy. Degradation curves showed the same trends for similar pavement structures, materials and traffic levels; on the other hand, differences in pavement characteristics, increased ESALs and various maintenance treatments significantly altered those trends.

    Full Text Available Evidence from a number of countries in Europe and North America point towards the secular declining trend in menarcheal age with considerable spatial variations over the past two centuries. Similar trends were reported in several developing countries from Asia, Africa and Latin America. However, data corroborating any secular trend in the menarcheal age of the Indian population remained sparse and inadequately verified.We examined secular trends, regional heterogeneity and association of socioeconomic, anthropometric and contextual factors with menarcheal age among ever-married women (15-49 years in India. Using the pseudo cohort data approach, we fit multiple linear regression models to estimate secular trends in menarcheal age of 91394 ever-married women using the Indian Human Development Survey.The mean age at menarche among Indian women was 13.76 years (95 % CI: 13.75, 13.77 in 2005. It declined by three months from 13.83 years (95% CI: 13.81, 13.85 among women born prior to 1955-1964, to nearly 13.62 years (95% CI: 13.58, 13.67 among women born during late 1985-1989. However, these aggregate national figures mask extensive spatial heterogeneity as mean age at menarche varied from 15.0 years in Himachal Pradesh during 1955-1964 (95% CI: 14.89-15.11 to about 12.1 years in Assam (95% CI: 11.63-12.56 during 1985-1989.The regression analysis established a reduction of nearly one month per decade, suggesting a secular decline in age at menarche among Indian women. Notably, the menarcheal age was significantly associated with the area of residence, geographic region, linguistic groups, educational attainment, wealth status, caste and religious affiliations among Indian women.

    Understanding long-term trends in injury morbidity is critical to prevention and intervention planning. The aim of this study was to assess long-term trends in injury morbidity rates in China from 1993 to 2013. Using data from the National Health Service Survey (NHSS), which is conducted every five years, crude and age-standardized prevalence during the previous two weeks and hospitalization rates in the last 12 months with 95% confidence intervals (CI) were calculated. The Rao-Scott Chi-square test examined injury morbidity differences across the five survey years by location (urban/rural), sex, age group, and household income. Percent changes in morbidity rate were approximated using logistic regressions. Sampling weights were applied to all analyses. In 2013, crude two-week injury prevalence in China was 0.46% (95% CI: 0.40%, 0.52%) and 12-month crude hospitalization rate was 0.70% (95% CI: 0.63%, 0.77%). Age-standardized injury prevalence increased 31.4% (95% CI: 7.6%, 60.6%) between 1993 and 2013 (29.4%, 95% CI: 6.7%, 56.9% from 1993-2003; 1.6%, 95% CI: -14.8%, 21.0% from 2003-2013), and age-standardized hospitalization rates rose 107.2% (95% CI: 75.1%, 145.2%) from 1993 to 2013 (-9.5%, 95% CI: -24.6%, 8.6% from 1993-2003 and 129.0%, 95% CI: 93.9%, 170.4% from 2003-2013). Subgroup analyses showed similar trends over time. The leading cause of injury was dislocation, sprain or strain for prevalence, and fractures for hospitalization. In conclusion, injury morbidity increased substantially from 1993 to 2013 in China. Inconsistent changes in two-week prevalence and 12-month hospitalization rate merit attention from researchers and policy-makers. Copyright © 2018 Elsevier Ltd. All rights reserved.

    A small but growing body of research indicates that progress in reducing child malnutrition is substantially uneven from place to place, even down to the district level within countries. Yet child malnutrition prevalence and trend estimates available for public health planning are mostly available only at the level of global regions and/or at country level. To support carefully targeted intervention to reduce child malnutrition, public health planners and policy-makers require access to more refined prevalence data and trend analyses than are presently available. Responding to this need in Ghana, this report presents trends in child malnutrition prevalence in socio-demographic groups within the country's geographic regions. The study uses the Ghana Demographic and Health Surveys (GDHS) data. The GDHS are nationally representative cross-sectional surveys that have been carried out in many developing countries. These surveys constitute one of the richest sources of information currently available to examine time trends in child malnutrition. Data from four surveys were used for the analysis: 1993, 1998, 2003 and 2008. The results show statistically significant declining trends at the national level for stunting (F (1, 7204) = 7.89, p ≤ .005), underweight (F (1, 7441) = 44.87, p ≤ .001) and wasting (F (1, 7130) = 6.19, p ≤ .013). However, analyses of the sex-specific trends revealed that the declining trends in stunting and wasting were significant among males but not among females. In contrast to the national trend, there were significantly increasing trends in stunting for males (F (1, 2004) = 3.92, p ≤ .048) and females (F (1, 2004) = 4.34, p ≤ .037) whose mothers had higher than primary education, while the trends decreased significantly for males and females whose mothers had no education. At the national level in Ghana, child malnutrition is significantly declining. However, the aggregate national trend masks important deviations in certain socio

    The Hydrologic Benchmark Network (HBN) is a long-term monitoring program established by the US Geological Survey in the 1960s to track changes in the streamflow and stream chemistry in undeveloped watersheds across the USA. Trends in stream chemistry were tested at 15 HBN stations over two periods (1970-2010 and 1990-2010) using the parametric Load Estimator (LOADEST) model and the nonparametric seasonal Kendall test. Trends in annual streamflow and precipitation chemistry also were tested to help identify likely drivers of changes in stream chemistry. At stations in the northeastern USA, there were significant declines in stream sulfate, which were consistent with declines in sulfate deposition resulting from the reductions in SO₂ emissions mandated under the Clean Air Act Amendments. Sulfate declines in stream water were smaller than declines in deposition suggesting sulfate may be accumulating in watershed soils and thereby delaying the stream response to improvements in deposition. Trends in stream chemistry at stations in other part of the country generally were attributed to climate variability or land disturbance. Despite declines in sulfate deposition, increasing stream sulfate was observed at several stations and appeared to be linked to periods of drought or declining streamflow. Falling water tables might have enhanced oxidation of organic matter in wetlands or pyrite in mineralized bedrock thereby increasing sulfate export in surface water. Increasing sulfate and nitrate at a station in the western USA were attributed to release of soluble salts and nutrients from soils following a large wildfire in the watershed.

    Purpose: To determine current European practice in interventional radiology regarding nursing care, anesthesia, and clinical care trends.Methods: A survey was sent to 977 European interventional radiologists to assess the use of sedoanalgesia, nursing care, monitoring equipment, pre- and postprocedural care, and clinical trends in interventional radiology. Patterns of sedoanalgesia were recorded for both vascular and visceral interventional procedures. Responders rated their preferred level of sedoanalgesia for each procedure as follows: (a) awake/alert, (b) drowsy/arousable, (c) asleep/arousable, (d) deep sedation, and (e) general anesthesia. Sedoanalgesic drugs and patient care trends were also recorded. A comparison was performed with data derived from a similar survey of interventional practice in the United States.Results: Two hundred and forty-three of 977 radiologists responded (25%). The total number of procedures analyzed was 210,194. The majority (56%) of diagnostic and therapeutic vascular procedures were performed at the awake/alert level of sedation, 32% were performed at the drowsy/arousable level, and 12% at deeper levels of sedation. The majority of visceral interventional procedures were performed at the drowsy/arousable level of sedation (41%), 29% were performed at deeper levels of sedation, and 30% at the awake/alert level. In general, more sedoanalgesia is used in the United States. Eighty-three percent of respondents reported the use of a full-time radiology nurse, 67% used routine blood pressure/pulse oximetry monitoring, and 46% reported the presence of a dedicated recovery area. Forty-nine percent reported daily patient rounds, 30% had inpatient hospital beds, and 51% had day case beds.Conclusion: This survey shows clear differences in the use of sedation for vascular and visceral interventional procedures. Many, often complex, procedures are performed at the awake/alert level of sedation in Europe, whereas deeper levels of sedation are

    The doctoral comprehensive or qualifying examination (CE/QE) is a traditional rite of passage into the community of scholars for the nursing profession. This exploratory, descriptive cross-sectional study examined trends in the process, timing, and methodology of comprehensive and qualifying examinations in nursing doctoral programs in the United States. Administrators from 45 schools responded to an online survey from 27 states across the country (37% response rate). Participants reported wide variations in the process. The most common method of implementation was the written take-home test (47%), two thirds of which had a subsequent oral examination. Eleven survey respondents (24%) reported using a form of the traditional written, timed, on-site examination; however, only 4 of these also followed up with an oral defense. Nine schools (20%) moved to a requirement for a written publishable paper; three schools consider the written proposal and its defense as the CE/QE. Approximately half had changed their policy in the past 5 years. With the increase in nursing doctor of philosophy programs over the past decade, information is needed to facilitate the development of methods to achieve program outcomes. An understanding of national CE/QE trends can provide a starting point for discussion and allow innovative ideas to meet the need of individual programs. Copyright © 2012 Elsevier Inc.

    To examine trends in the prevalence of domestic violence since 1997, 1 year prior to the introduction of legislative countermeasures and accompanying services in South Korea, and to analyze what socio-demographic characteristics of perpetrators contribute to spousal violence and whether there were any changes in risk factors over time. This study used two sets of nationally representative household samples: married or cohabiting couples of 1,540 from the 1999 national survey and 3,269 from the 2010 National Survey of Domestic Violence. Frequency analysis was used to measure the prevalence of intimate partner violence (IPV), and cross-tabulation, correlation, and logistic regression analyses were used to look for socio-demographic risk factors of spousal physical violence and patterns of change over time. The frequency analysis showed that the IPV prevalence dropped by approximately 50%, from 34.1% in 1999 to 16.5% in 2010, though it was still higher than many other countries. The cross-tabulation and logistic regression analyses suggested that men with low socio-demographic characteristics were generally more violent, though this tendency did not apply to women. Instead, younger women seemed to be more violent than older women. Last, different levels of household income were associated with different levels of IPV in 2010, but no linear trend was detected. In this study, IPV prevalence trends and risk factors of two different time periods were discussed to provide implications for tackling the IPV problem. Future countermeasures must build on understanding about men with low socio-demographic status and younger women, who were more violent in marital relationships. © The Author(s) 2015.

    Full Text Available Management of Technology (MOT is defined as an academic discipline of management that enables organizations to manage their technological fundamentals to create competitive advantage. MOT covers a wide range of contents including administrative strategy, R&D management, manufacturing management, technology transfer, production control, marketing, accounting, finance, business ethics, and others. For each topic, researchers have conducted their MOT research at various levels. However, a practical and pragmatic side of MOT surely affects its research trends. Finding changes of MOT research trends, or the chronological transitions of principal subjects, can help understand the key concepts of current MOT. This paper studied a bottom-up trend in research fields in MOT by applying a text-mining method to the conference proceedings of IAMOT (International Association for Management of Technology. First, focusing on only nouns found several keywords, which more frequently emerge over time in the IAMOT proceedings. Then, expanding the scope into other parts of speech viewed the keywords in a natural context. Finally, it was found that the use of an important keyword has qualitatively and quantitatively extended over time. In conclusion, a bottom-up trend in MOT research was detected and the effects of the social situation on the trend were discussed.Keywords: Management of Technology; Text Mining; Research Trend; Bottom-up Trend; Patent

    Research in informal science education (ISE) become more interesting area in science education for a few decades. The main purpose of this research is to analyse research articles in 30 issues of top three international journals in science education; Journal of Research in Science Teaching, Science Education, and the International Journal of Science Education. The research articles during 2007 and 2016 were reviewed and analysed according to the authors' nationality, informal science education's research topics, research paradigms, methods of data collection and data analysis. The research findings indicated that there were 201 published papers related to informal science education, successfully submitted by 469 authors from 27 different countries. In 2008, there was no article related to informal science education. Statistical analyses showed that authors from USA are the most dominant, followed by UK and Israel. The top three ISE's research topics most frequently investigated by the researchers were regarding students' informal learning, public understanding in science, and informal perspectives, policies and paradigms. It is also found that theoretical framework used in informal science education which is becoming more strongly rooted is in a mix of the sociocultural and constructivist paradigms, with a growing acceptance of qualitative research methods and analyses.

    Background. Nonalcoholic fatty liver disease is now acknowledged as a complex public health issue linked to sedentary lifestyle, obesity, and related disorders like type 2 diabetes and metabolic syndrome. Aims. We aimed to retrieve its trends out of the huge amount of published data. Therefore, we conducted an extensive literature search to identify possible biomarker and/or biomarker combinations by retrospectively assessing and evaluating common and novel biomarkers to predict progression and prognosis of obesity related liver diseases. Methodology. We analyzed finally 62 articles accounting for 157 cohorts and 45,288 subjects. Results. Despite the various approaches, most cohorts were considerably small and rarely comparable. Also, we found that the same standard parameters were measured rather than novel biomarkers. Diagnostics approaches appeared incomparable. Conclusions. Further collaborative investigations on harmonizing ways of data acquisition and identifying such biomarkers for clinical use are necessary to yield sufficient significant results of potential biomarkers.

    2006-01-01

    Separation of acid gases and lower hydrocarbon from raw natural gas has been a challenging problem in a gas processing unit. Despite the availability of chemical and cryogenic routes, search for a better alternative has been on for the last several decades. Considerable success has been achieved in the recent years by use of polymeric membrane and many units are operating using hollow fiber and spirally wound modules. The initial success notwithstanding the quest for better membrane and strategically designed modules has gained more momentum in the recent years. While research inputs to modify rubbery membranes or to develop new glassy membranes are continuing, inorganic membrane have attracted a lot of attention because of a number of reasons such as thermal and chemical stability, mechanical strength and the advantage of engineered pores. In the above perspective it appears necessary to make a review of the present status of research as well as applications in relation to both polymeric and inorganic membranes for raw natural gas processing. The present paper is an attempt in this direction. Experimental findings reported in the literature together with novel theories that will eventually help in tailoring membranes both chemically and physically have been critically analyzed and the trends in the future direction of research have been identified. A survey of application of membrane technology for acid gas separation in industries world wide has been made

As a readout of research output in the US compared with other countries, assessment of original research articles published by US-based authors in ten clinical and basic science journals during 2000 to 2015 showed a steady decline of articles in high-ranking journals or no significant change in mid-ranking journals. In contrast, publication output originating from China-based investigators, in both high- and mid-ranking journals, has steadily increased commensurate with significant growth in R&D expenditures. These observations support the current concerns of stagnant and year-to-year uncertainty in US federal funding of biomedical research. PMID:28614799

    Cook-Deegan Robert M

    2008-10-01

    Full Text Available Abstract Background Over the past two decades, genomics has evolved as a scientific research discipline. Genomics research was fueled initially by government and nonprofit funding sources, later augmented by private research and development (R&D funding. Citizens and taxpayers of many countries have funded much of the research, and have expectations about access to the resulting information and knowledge. While access to knowledge gained from all publicly funded research is desired, access is especially important for fields that have broad social impact and stimulate public dialogue. Genomics is one such field, where public concerns are raised for reasons such as health care and insurance implications, as well as personal and ancestral identification. Thus, genomics has grown rapidly as a field, and attracts considerable interest. Results One way to study the growth of a field of research is to examine its funding. This study focuses on public funding of genomics research, identifying and collecting data from major government and nonprofit organizations around the world, and updating previous estimates of world genomics research funding, including information about geographical origins. We initially identified 89 publicly funded organizations; we requested information about each organization's funding of genomics research. Of these organizations, 48 responded and 34 reported genomics research expenditures (of those that responded but did not supply information, some did not fund such research, others could not quantify it. The figures reported here include all the largest funders and we estimate that we have accounted for most of the genomics research funding from government and nonprofit sources. Conclusion Aggregate spending on genomics research from 34 funding sources averaged around $2.9 billion in 2003 – 2006. The United States spent more than any other country on genomics research, corresponding to 35% of the overall worldwide public

    Thailand borders some of the world's largest methamphetamine and opioid producing countries and trafficking routes. Thailand's 'War on Drugs' campaign was launched in 2003. This study reports trends in illicit substance use in Thailand over the period 2001-2011. National Household surveys on illicit drug use were conducted in 2001, 2003, 2007, 2008 and 2011. A stratified multi-stage cluster random sampling technique was implemented for each survey. Provinces in four regions were systematically selected using a probability proportionate to the size of the targeted population. Participants were interviewed using structured questionnaires on their history of substance use. The prevalence of illicit drug use within the past drastically decreased from 4.5% in 2001 to 1.0% in 2003 (P survey. Other types of illicit drugs were less commonly used in Thailand. There was a decrease in prevalence of illicit drug use within the past year between 2001 and 2003 in Thailand. Since 2003, the past year prelavence of illicit drug use has remained relatively stable. From 2001 to 2011, cannabis, kratom and yaba have remained the three most commonly reported types of illicit drugs used in Thailand. © 2018 Australasian Professional Society on Alcohol and other Drugs.

  19. TRENDS IN RETIREMENT SAVING: EVIDENCE FROM AN ONLINE SURVEY OF ROMANIAN HOUSEHOLDS

    Directory of Open Access Journals (Sweden)

    GURAN (TEODORESCU ILEANA

    2015-04-01

    Full Text Available In the context of the population aging and the demographic crisis throughout Europe and the developed world, the public pension systems will become increasingly strained as the proportion of pensioners to the working population will continue to increase. Empirical evidence shows that individuals fail to save enough for retirement to compensate for the less than optimal level of public pensions, and thus are facing the risk of a decrease in the standard of living in their post-retirement years. This larger context makes the study of retirement saving behavior an important matter. The objective of this paper is to document current trends in retirement saving behavior from the data collected through an online survey of Romanian households. The survey was distributed as an online questionnaire that collected 1285 of responses. The survey’s objective was to document households’ financial situation, as well as other psychological and social factors that might explain saving behavior. The analysis of the survey results indicates that there is a gap between intentions and actions when it comes to retirement saving. This gap and the resulting suboptimal retirement saving rates are explained in behavioral economics literature by anomalies in the inter-temporal choices of individuals, subject to self-control issues. We will see to what extent this gap is due to self-control issues and to what extent it is explained by the current financial situation of individuals. We will also conclude about possible retirement saving behavior influencing factors and motives.

  1. Evaluating the power to detect temporal trends in fishery independent surveys: A case study based on Gillnets Set in the Ohio waters of Lake Erie for walleye

    Science.gov (United States)

    Wagner, Tyler; Vandergoot, Christopher S.; Tyson, Jeff

    2009-01-01

    Fishery-independent (FI) surveys provide critical information used for the sustainable management and conservation of fish populations. Because fisheries management often requires the effects of management actions to be evaluated and detected within a relatively short time frame, it is important that research be directed toward FI survey evaluation, especially with respect to the ability to detect temporal trends. Using annual FI gill-net survey data for Lake Erie walleyes Sander vitreus collected from 1978 to 2006 as a case study, our goals were to (1) highlight the usefulness of hierarchical models for estimating spatial and temporal sources of variation in catch per effort (CPE); (2) demonstrate how the resulting variance estimates can be used to examine the statistical power to detect temporal trends in CPE in relation to sample size, duration of sampling, and decisions regarding what data are most appropriate for analysis; and (3) discuss recommendations for evaluating FI surveys and analyzing the resulting data to support fisheries management. This case study illustrated that the statistical power to detect temporal trends was low over relatively short sampling periods (e.g., 5–10 years) unless the annual decline in CPE reached 10–20%. For example, if 50 sites were sampled each year, a 10% annual decline in CPE would not be detected with more than 0.80 power until 15 years of sampling, and a 5% annual decline would not be detected with more than 0.8 power for approximately 22 years. Because the evaluation of FI surveys is essential for ensuring that trends in fish populations can be detected over management-relevant time periods, we suggest using a meta-analysis–type approach across systems to quantify sources of spatial and temporal variation. This approach can be used to evaluate and identify sampling designs that increase the ability of managers to make inferences about trends in fish stocks.

    2012-02-01

    This article provides a systematic review of the team knowledge literature and guidance for further research. Recent research has called attention to the need for the improved study and understanding of team knowledge. Team knowledge refers to the higher level knowledge structures that emerge from the interactions of individual team members. We conducted a systematic review of the team knowledge literature, focusing on empirical work that involves the measurement of team knowledge constructs. For each study, we extracted author degree area, study design type, study setting, participant type, task type, construct type, elicitation method, aggregation method, measurement timeline, and criterion domain. Our analyses demonstrate that many of the methodological characteristics of team knowledge research can be linked back to the academic training of the primary author and that there are considerable gaps in our knowledge with regard to the relationships between team knowledge constructs, the mediating mechanisms between team knowledge and performance, and relationships with criteria outside of team performance, among others. We also identify categories of team knowledge not yet examined based on an organizing framework derived from a synthesis of the literature. There are clear opportunities for expansion in the study of team knowledge; the science of team knowledge would benefit from a more holistic theoretical approach. Human factors researchers are increasingly involved in the study of teams. This review and the resulting organizing framework provide researchers with a summary of team knowledge research over the past 10 years and directions for improving further research.

  11. [New Paradigms? Current Trends within National and International Psychotherapy Research].

    Science.gov (United States)

    Strauß, Bernhard

    2015-09-01

    This article is devoted to the question which paradigms currently determine psychotherapy and psychotherapy research, and if there are indicators of paradigm changes in this field. The question of the efficacy and effectiveness (including the effectiveness of a transfer of psychotherapeutic knowledge to service) is specifically focussed as well as the question of the central therapeutic factors and the significance of the person of the therapist. It is argued that there are really some signals of a paradigm switch, with a turn away from controlled outcome research, representing only a minor part of patients in need of psychotherapy, towards a more specific process oriented research, also considering differential effects of the therapist. The most prominent indicator of a paradigm change is reflected by an increasing influence of patient oriented psychotherapy research which - consequently - should also be supported by the insurances as well as the funding organisations. © Georg Thieme Verlag KG Stuttgart · New York.

    The aim of this study was to analyze trends in indicators of smoking in Brazilian State capitals, according to the Surveillance System for Risk and Protective Factors for Chronic Illnesses Using a Telephone Survey (VIGITEL) in adults, from 2006 to 2011. A simple linear regression model was used (a = 5%). There was a decrease in the prevalence of smokers and heavy smokers among men and in individuals 35 to 54 years of age. Smoking also decreased among individuals with 9-11 years of schooling and in the Northeast, North, and Central West regions. For heavy smokers, the largest decline was in the Northeast. Brazil's regulatory policy has been responsible for the decline in tobacco prevalence.

    The purpose of this study was to describe and summarize the characteristics of contemporary holistic nursing research (HNR) published nationally. A descriptive research design was used for this study. Data for this study came from a consecutive sample of 579 studies published in six journals determined as most consistent with the scope of holistic nursing from 2010 to 2015. The Johns Hopkins level of evidence was used to identify evidence generated, and two criteria-power analysis for quantitative research and trustworthiness for qualitative research-were used to describe overall quality of HNR. Of the studies, 275 were considered HNR and included in the analysis. Caring, energy therapies, knowledge and attitudes, and spirituality were the most common foci, and caring/healing, symptom management, quality of life, and depression were the outcomes most often examined. Of the studies, 56% were quantitative, 39% qualitative, and 5% mixed-methods designs. Only 32% of studies were funded. Level III evidence (nonexperimental, qualitative) was the most common level of evidence generated. Findings from this study suggest ways in which holistic nurse researchers can strengthen study designs and thus improve the quality of scientific evidence available for application into practice and improve health outcomes.

  15. Consciousness and working memory: Current trends and research perspectives.

    Velichkovsky, Boris B

    2017-10-01

    Working memory has long been thought to be closely related to consciousness. However, recent empirical studies show that unconscious content may be maintained within working memory and that complex cognitive computations may be performed on-line. This promotes research on the exact relationships between consciousness and working memory. Current evidence for working memory being a conscious as well as an unconscious process is reviewed. Consciousness is shown to be considered a subset of working memory by major current theories of working memory. Evidence for unconscious elements in working memory is shown to come from visual masking and attentional blink paradigms, and from the studies of implicit working memory. It is concluded that more research is needed to explicate the relationship between consciousness and working memory. Future research directions regarding the relationship between consciousness and working memory are discussed. Copyright © 2017 Elsevier Inc. All rights reserved.

    Students aged 16-24 years are at greatest risk for interpersonal violence and the resulting short and long-term health consequences. Electronic survey methodology is well suited for research related to interpersonal violence. Yet methodological questions remain about best practices in using electronic surveys. While researchers often indicate that potential participants receive multiple emails as reminders to complete the survey, little mention is made of the sender of the recruitment email. The purpose of this analysis is to describe the response rates from three violence-focused research studies when the recruitment emails are sent from a campus office, researcher or survey sampling firm. Three violence-focused studies were conducted about interpersonal violence among college students in the United States. Seven universities and a survey sampling firm were used to recruit potential participants to complete an electronic survey. The sender of the recruitment emails varied within and across the each of the studies depending on institutional review boards and university protocols. An overall response rate of 30% was noted for the 3 studies. Universities in which researcher-initiated recruitment emails were used had higher response rates compared to universities where campus officials sent the recruitment emails. Researchers found lower response rates to electronic surveys at Historically Black Colleges or Universities and that other methods were needed to improve response rates. The sender of recruitment emails for electronic surveys may be an important factor in response rates for violence-focused research. For researchers identification of best practices for survey methodology is needed to promote accurate disclosure and increase response rates.

    Iwasaki, Toshiyasu; Yoshida, Kazuo

    2010-01-01

    Large research projects on low dose radiation effects in Europe and US over the past decade have provided limited scientific knowledge which could underpin the validation of radiation protection systems. Recently in Europe, there have been repeated discussions and dialogues to improve the situation, and as the consequence, the circumstances surrounding low dose radiation risks are changing. In 2009, Multidisciplinary European Low Dose Initiative (MELODI) was established as a trans-national organization capable of ensuring appropriate governance of research in the pursuit of a long term shared vision, and Low Dose Research towards Multidisciplinary Integration (DoReMi) network was launched in 2010 to achieve fairly short term results in order to prove the validity of the MELODI approach. It is expected to be very effective and powerful activities to facilitate the reduction of uncertainties in the understanding of low dose risks, but the regulatory requests rushing the reinforcement of radiological protection regulations based on the precautional principles are more increasing. To develop reasonable radiological protection systems based on scientific evidences, we need to accelerate to collect scientific evidences which could directly underpin more appropriate radiation protection systems even in Japan. For the purpose, we Japan need to develop from an independent standpoint and share as a multidisciplinary vision a long term and holistic research strategy which enables to enhance Japanese advantages such as low dose rate facilities and animal facilities, as soon as possible.

    The objective of this study was to review the opinions and experiences of renal care professionals to examine dietary trends among patients with chronic kidney disease (CKD) and problems associated with the clinical management of hyperphosphatemia. This was an online survey comprising open and closed questions requesting information on patient dietary trends and the clinical management of hyperphosphatemia. The study was conducted in 4 European countries (the Netherlands, Spain, Sweden, and the United Kingdom). Participants were 84 renal care professionals. This was an online survey. Responder-reported experiences and perceptions of patient dietary trends and hyperphosphatemia management were assessed. Most survey responders (56%) observed an increase in the consumption of processed convenience food, 48% noticed an increase in the consumption of foods rich in phosphorus-containing additives, and 60% believed that there has been a trend of increasing patient awareness of the phosphorus content of food. Patients undergoing hemodialysis (HD) were most likely to experience difficulties in following advice on dietary phosphorus restriction (38% of responders estimated that 25-50% of their patients experienced difficulties, and 29% estimated that 51-75% experienced difficulties). Maintaining protein intake and restricting dietary phosphorus were perceived as being equally important by at least half of responders for predialysis patients (56%) and for those undergoing peritoneal dialysis and HD (54% and 50%, respectively). There were international variations in dietary trends and hyperphosphatemia management. Although most responders have observed a trend of increasing awareness of the phosphorus content of food among patients with CKD, the survey results indicate that many patients continue to experience difficulties when attempting to restrict dietary phosphorus. The survey responses reflect the global trend of increasing consumption of processed convenience foods and

  12. Temporal Trends and Changing Racial/ethnic Disparities in Alcohol Problems: Results from the 2000 to 2010 National Alcohol Surveys.

    2013-09-28

    Economic conditions and drinking norms have been in considerable flux over the past 10 years. Accordingly, research is needed to evaluate both overall trends in alcohol problems during this period and whether changes within racial/ethnic groups have affected racial/ethnic disparities. We used 3 cross-sectional waves of National Alcohol Survey data (2000, 2005, and 2010) to examine a) temporal trends in alcohol dependence and consequences overall and by race/ethnicity, and b) the effects of temporal changes on racial/ethnic disparities. Analyses involved bivariate tests and multivariate negative binomial regressions testing the effects of race/ethnicity, survey year, and their interaction on problem measures. Both women and men overall showed significant increases in dependence symptoms in 2010 (vs. 2000); women also reported increases in alcohol-related consequences in 2010 (vs. 2000). (Problem rates were equivalent across 2005 and 2000.) However, increases in problems were most dramatic among Whites, and dependence symptoms actually decreased among Latinos of both genders in 2010. Consequently, the long-standing disparity in dependence between Latino and White men was substantially reduced in 2010. Post-hoc analyses suggested that changes in drinking norms at least partially drove increased problem rates among Whites. Results constitute an important contribution to the literature on racial/ethnic disparities in alcohol problems. Findings are not inconsistent with the macroeconomic literature suggesting increases in alcohol problems during economic recession, but the pattern of effects across race/ethnicity and findings regarding norms together suggest, at the least, a revised understanding of how recessions affect drinking patterns and problems.

  13. Government policy, research and stakeholder confidence - Current Trends in Canada

    Letourneau, Carmel

    2006-01-01

    The author addressed the topic of government Policy, research and stakeholder Confidence from the perspective of government policy makers in Canada. The presentation reviewed the question: why carry out more research into methods of long-term management of nuclear fuel waste? In addressing this question, the author provided some perspectives that were expressed by the Canadian public, since reflected in the Final Study of management approaches led by the Nuclear Waste Management Organization (NWMO), an organization set up by the nuclear industry to study options for the long-term management of nuclear fuel waste. The Final Study was submitted to the federal Minister of Natural Resources in November 2005 as required under the Nuclear Fuel Waste Act. The NWMO's Final Study emphasized the important role of continuous learning, a key element in the NWMO's recommendation of Adaptive Phased Management. It was reported that the NWMO work had identified many reasons to carry out further research. Regardless of the management approach adopted, activities to manage radioactive waste will continue for a very long time. Any management program could be expected to apply the best practice available at the time. A program that will evolve over a long period of time will have many opportunities for improvements to increase performance, enhance effectiveness, and address rising societal concerns. It was suggested that, to realize these benefits, there needs to be a vibrant and robust research and development effort during management program development and execution, a period that will last many generations, and enable implementers to adapt to a changing environment. Among the reasons put forward for continuing research were, to: - Embody the principles of continuous learning which encourages standards of excellence and integrity; - Prepare for facility siting, design, licensing, development and operations to improve designs, minimize costs, enhance schedules, and reduce

  15. Emerging trends in contract research industry in India.

    Science.gov (United States)

    Drabu, Sushma; Gupta, Alka; Bhadauria, Anupama

    2010-09-01

    A Contract Research Organization (CRO) is a service organization that provides support to the pharmaceutical industry and offers a wide range of "outsourced" pharmaceutical research services to aid in R&D process and is thus an essential tool for undertaking clinical trials in the present scenario when high stakes are involved in the drug discovery process. This industry also offers a safe option of investment as the industry is largely recession-proof, with a significant upscale growth. Presently India occupies a very small pie of the global market share in the Clinical Trials Industry but it is estimated to conduct nearly 5% of global clinical trials by 2012. The global CRO industry valued $18 bn in 2008 and the market is expected to grow at an annual rate of 14% between 2009 and 13. Top multinational pharmaceuticals companies are venturing into the Indian business, in collaboration with the Indian Drug Companies. According to a recent study by Mckinsey & Company, the Indian Clinical Research Industry can attract $1.5 bn of revenue from US and EU by 2010. Such an increase in outsourcing from the western countries has led the global pharma companies and Indian entrepreneurs to set up Contract Research Organizations (CROs) in India. To bring this into realization and fulfil the market demand, while simultaneously aiding in improving the country's economical standards and market position, joint and well-coordinated efforts on part of the government, industry, and working professionals are needed in terms of regulatory affairs, audits, transparency in work affairs, garnering patient confidence, and pharmacovigilance.

  17. Suicide Research and Adolescent Suicide Trends in New Zealand

    Directory of Open Access Journals (Sweden)

    Said Shahtahmasebi

    2008-01-01

    Full Text Available In recent years, there have been a number of claims and counterclaims from suicide research using time series and longitudinal data; in particular, the linkage of increased antidepressant prescriptions to a decrease in suicide rates. Suicide time series appear to have a memory compounded with seasonal and cyclic effects. Failure to take into account these properties may lead to misleading conclusions, e.g., a downward blip is interpreted as the result of current knowledge and public health policies, while an upward blip is explained as suicide being complex depending on many variables requiring further research. In previous publications, I argued that this misuse of time series data is the result of an uncritical acceptance of a medical model that links mental ill-health to suicide. The consequences of such research behaviour are further increases in antidepressant prescriptions and medications to those who should not be prescribed them, with adverse effects showing across the population, e.g., the prescription of antidepressants to very young children (some under 1 year of age in New Zealand. Moreover, the New Zealand Evidence-based Health Care Bulletin recommends an authoritarian approach for every interaction with a young person to check their psychosocial well-being. When viewed holistically, this kind of human behaviour makes researchers, policy makers (politicians, treatment, and practitioners, and society in general part of the problem rather than the solution. This paper explores some dynamic aspects of suicide, using only official data with particular reference to youth suicide, and suggests that the medical model of suicide is only an attempt to treat depression without addressing suicide, and recommends the creation of a unified database through understanding the society that individuals live in. It is hoped that this paper will stimulate debate and the collaboration of international experts regardless of their school of thought.

    Immigration has a strong impact on the development of health systems, medicine and science worldwide. Therefore, this article provides a descriptive study on the overall research output. Utilizing the scientific database Web of Science, data research was performed. The gathered bibliometric data was analyzed using the established platform NewQIS, a benchmarking system to visualize research quantity and quality indices. Between 1900 and 2016 a total of 6763 articles on immigration were retrieved and analyzed. 86 different countries participated in the publications. Quantitatively the United States followed by Canada and Spain were prominent regarding the article numbers. On comparing by additionally taking the population size into account, Israel followed by Sweden and Norway showed the highest performance. The main releasing journals are the Public Health Reports, the Journal of Immigrant and Minority Health and Social Science & Medicine. Over the decades, an increasing number of Public, Environmental & Occupational Health articles can be recognized which finally forms the mainly used subject area. Considerably increasing scientific work on immigration cannot only be explained by the general increase of scientific work but is also owed to the latest development with increased mobility, worldwide crises and the need of flight and migration. Especially countries with a good economic situation are highly affected by immigrants and prominent in their publication output on immigration, since the countries' publication effort is connected with the appointed expenditures for research and development. Remarkable numbers of immigrants throughout Europe compel medical professionals to consider neglected diseases, requires the public health system to restructure itself and finally promotes science.

    In this special issue reflect the developments in the fields of earthworm research and vermitechnology. Charles Darwins observation on earthworms is a milestone in understanding the soil biology and enormous contribution to some aspects of the genesis of humus and of its role in soils. Earthworms are the best known soil inhabiting animals commonly called friends of farmers due to the beneficial role they play in soil. The research on earthworms has gained importance in India as well as in other countries. In the year 1981, an international symposium entitled Earthworm Ecology: Darwin to Vermiculture was held at Cumbria, UK, to commemorate the centenary celebration of Darwins book The Formation of Vegetable Mould through the Action of Worms, with Observations on Their Habits that was published in 1881 by Murray, London, UK. In the year 2000, Vermillenium-an international workshop and symposium- was held at Kalamazoo, USA, to realize the progress achieved in this field after a decade (since 1991). Recently, Ninth International Symposium on Earthworm Ecology (ISEE-9) that was held at Xalapa, Mexico, during the 5th to 10th of September 2010 clearly proved the importance of earthworms and vermitechnology by the participation of scientists from different countries. About 300 papers were received from the researchers across the world

    To examine trends in leisure time physical activity and inactivity in Australians aged 15 years or older from 1989 to 2011. We used data from six Australian National Health Surveys conducted from 1989/90 to 2011/12 in which physical activity was assessed using comparable questions. Analyses examined trends in the prevalence of sufficient physical activity (≥150 minutes/week moderate-to-vigorous physical activity) and of inactivity (benefits from sufficient physical activity. Maintenance of consistent physical activity questions in future National Health Surveys will facilitate long term tracking of physical activity levels in the Australian population. © 2017 The Authors.

    2016-02-01

    The past decade has yielded changes in the education and training of audiologists and technological advancements that have become widely available for clinical balance function testing. It is unclear if recent advancements in vestibular instrumentation or the transition to an AuD degree have affected audiologists' vestibular clinical practice or opinions. The purpose of this study was to examine predominant opinions and practices for vestibular assessment (VA) and vestibular rehabilitation (VR) over the past decade and between master's- and AuD-level audiologists. A 31-question survey was administered to audiologists via U.S. mail in 2003 (N = 7,500) and electronically in 2014 (N = 9,984) with a response rate of 12% and 10%, respectively. There was an increase in the number of audiologists providing vestibular services in the past decade. Most respondents agreed that audiologists were the most qualified professionals to conduct VA. Less than half of the surveyed audiologists felt that graduate training was adequate for VA. AuD-level audiologists were more satisfied with graduate training and felt more comfortable performing VA compared to master's-level audiologists. Few respondents agreed that audiologists were the most qualified professionals to conduct VR or that graduate training prepared them to conduct VR. The basic vestibular test battery was unchanged across surveys and included: calorics, smooth pursuit, saccades, search for spontaneous, positional, gaze and optokinetic nystagmus, Dix-Hallpike, case history, and hearing evaluation. There was a trend toward greater use of air (versus water) calorics, videonystagmography (versus electronystagmography), and additional tests of vestibular and balance function. VA is a growing specialty area in the field of audiology. Better training opportunities are needed to increase audiologists' knowledge and skills for providing vestibular services. The basic tests performed during VA have remained relatively unchanged

    2015-06-01

    Remote sensing was introduced into China in 1970s and then began to flourish. At present, China has developed into a big remote sensing country, and remote sensing is increasingly playing an important role in various fields of national economic construction and social development. Based on China Academic Journals Full-text Database and China Citation Database published by China National Knowledge Infrastructure, this paper analyzed academic characteristics of 963 highly cited papers published by 16 professional and academic journals in the field of surveying and mapping from January 2010 to December 2014 in China, which include hot topics, literature authors, research institutions, and fundations. At the same time, it studied a total of 51,149 keywords published by these 16 journals during the same period. Firstly by keyword selection, keyword normalization, keyword consistency and keyword incorporation, and then by analysis of high frequency keywords, the progress and prospect of China's remote sensing technology in data acquisition, data processing and applications during the past five years were further explored and revealed. It can be seen that: highly cited paper analysis and word frequency analysis is complementary on subject progress analysis; in data acquisition phase, research focus is new civilian remote sensing satellite systems and UAV remote sensing system; research focus of data processing and analysis is multi-source information extraction and classification, laser point cloud data processing, objectoriented high resolution image analysis, SAR data and hyper-spectral image processing, etc.; development trend of remote sensing data processing is quantitative, intelligent, automated, and real-time, and the breadth and depth of remote sensing application is gradually increased; parallel computing, cloud computing and geographic conditions monitoring and census are the new research focuses to be paid attention to.

  8. A Bibliometric Analysis on “Fertility Rate” Research Trends

    Directory of Open Access Journals (Sweden)

    2016-07-01

    Full Text Available The systematic literature search on the fertility rate was performed on articles from the Web of Science compiled by the Institute of Scientific Information (ISI to provide major publication characteristics. All articles related to Fertility from year 1980 to 2011 were analyzed with the bibliometric approach using non-parametrics techniques. Total Citation, Citation per year and Cited References were significantly different between the 80’s, 90’s and 2000’s, with more than a 100% increase in the number of publication. The association between number of authors and citation per year were significantly weak. Number of publication in a journal posed a poor negative association with the citation per year. Similarity between Authors Keyword and KeyWords Plus® do not promote the increase in citation per year. The author’s affiliation and country of publication would be an interesting exploration for future fertility research. The bibiliometric analyses on Fertility is rather new and vital, as the key finding will provide researchers guidance in the literature search and future publication.

The authors referred to, mainly Americans, question the impact of continuity and change and, on the other hand, analyze the impact of interpersonal differences in the evolution of itineraries.From a strictly academic approach, one of the main contributions of the application of the concept of leisure itineraries to the study of consolidation lies in the treatment of leisure as a process. This point of view moves us away from the study of purely objective aspects and leads us to personal implications, without which the meaning of leisure experience is difficult to understand. At the end of the paper, the challenges the study opens and the contributions involving both the orientation of the educational offer and the pedagogy of leisure are presented. The study of leisure itineraries allows us to reinforce the importance of leisure as a factor of human development throughout life and legitimizes its support through specific policies, management models and intervention actions.

  11. Tobacco smoking – popularity and main trends on research

    Full Text Available Each year smoking leads to the premature death of over 5 million people around the world. However, the tobacco industry took actions like introducing cigarettes which contain less nicotine and tar aimed at not only maintaining the old clientele, but also attracting a new one. The knowledge of the adverse health effects of smoking became widespread in the second half of the 20th century and changed attitudes towards smoking. In recent years, in many markets in the world a new device representing an alternative to tobacco products was introduced. Electronic cigarettes are designed to deliver nicotine into the respiratory system in the form of an aerosol. They have been gaining more and more popularity, as evidenced by the increase in the percentage of users as well as in the numbers of publications about them. Currently, opinions are divided and the e-cigarette has almost as many supporters as opponents. All this resembles the situation concerning conventional cigarettes in the 20th century. The aim of the study is to gather the most significant information concerning, on the one hand, the spreading popularity of tobacco smoking and, on the other, the research topics undertaken by contemporary scientists, as well as the government actions meant to protect from dangers of nicotine addiction in the 20th and 21st century. New developments of products containing this highly addictive substance call for systematic research in the interest of public health.

    Extensive fossil fuel consumption in almost all human activities led to some undesirable phenomena such as atmospheric and environmental pollutions, which have not been experienced before in known human history. Consequently, global warming, greenhouse affect, climate change, ozone layer depletion and acid rain terminologies started to appear in the literature frequently. Since 1970, it has been understood scientifically by experiments and researches that these phenomena are closely related to fossil fuel uses because they emit greenhouse gases such as carbon dioxide (CO{sub 2}) and methane (CH{sub 4}) which hinder the long wave terrestrial radiation to escape into space, and consequently, the earth troposphere becomes warmer. In order to avoid further impacts of these phenomena, the two concentrative alternatives are either to improve the fossil fuel quality with reductions in their harmful emissions into the atmosphere or more significantly to replace fossil fuel usage as much as possible with environmentally friendly, clean and renewable energy sources. Among these sources, solar energy comes at the top of the list due to its abundance, and more evenly distribution in nature than any other renewable energy types such as wind, geothermal, hydro, wave and tidal energies. It must be the main and common purpose of humanity to sustain environment for the betterment of future generations with sustainable energy developments. On the other hand, the known limits of fossil fuels compel the societies of the world in the long run to work jointly for their gradual replacement by renewable energy alternatives rather than the quality improvement of fossil sources. Solar radiation is an integral part of different renewable energy resources. It is the main and continuous input variable from practically inexhaustible sun. Solar energy is expected to play a very significant role in the future especially in developing countries, but it has also potential prospects for developed

    Clinical trials have identified secondary caries and bulk fracture as the main causes for composite restoration failure. As a measure to avoid frequent reinterventions for restoration replacement, composites with some sort of defense mechanism against biofilm formation and demineralization, as well as materials with lower susceptibility to crack propagation are necessary. Also, the restorative procedure with composites are very time-consuming and technically demanding, particularly concerning the application of the adhesive system. Therefore, together with bulk-fill composites, self-adhesive restorative composites could reduce operator error and chairside time. This literature review describes the current stage of development of remineralizing, antibacterial and self-healing composites. Also, an overview of the research on fiber-reinforced composites and self-adhesive composites, both introduced for clinical use in recent years, is presented.

    An up-to-date progress of the international laser research and development is given in this article. The number of scientific publications and filed patents are considered as a figure of merit and based on these numbers the growth pace and important aspects are investigated. We have used the Science Finder Scholar search engine, which indexes more than 4000 journals, in different languages, and represents most significant published materials in laser science and engineering. The growth of the laser and related fields are described in terms of resulting scientific publications for the period of 1990-2003. The share of top nations in scientific publications, and in particular laser publications in terms of their gross domestic product (GDP) is presented. It is noted that the four countries including the USA, Japan, Germany and China have a laser publication contribution of 58.9% while the rest of the world including 189 countries contribute 41.1%. However, for the case of patent, which is a more important factor, these four countries hold a share of 90.1% while the remaining nations have a small share of 9.9%. The USA heads all the nations in the number of scientific publications, citations, and laser publications, however, in terms of accepted laser patents Japan shows a big lead. Scientific scopes of the laser systems are presented and some requirements to be met in each field are described. The key points in this field of research, which might be helpful in the future development of the laser technology are discussed.

    The AOD prevention programs of the 1990s should be resiliency-focused and include interventions of sufficient dosage and strength. Although some child behavioral technology exists to tackle successfully changes in resiliency, additional prevention strategies need to be developed and studied. In some way, the prevention field is hampered by the lack of sufficient research in the child and adolescent psychiatry and psychology fields, that includes transactional research in parenting and child rearing for high-risk youth. We simply do not know enough to determine how parents and other adults can best foster resilience in children. Questions that arise include how much to protect children from environmental stressors and how much to push them to confront new life stressors in the form of challenges to develop new skills or talents. There are no simple answers to these questions, but a number of useful guidelines could help parents and teachers to increase resilience in youth. Some of the guidelines currently being stressed include developing in youth an increased sense of responsibility for their own success, helping them to identify their talents, motivating them to dedicate their lives to helping society rather than feeling their only purpose in life is to be consumers, providing realistic appraisals and feedback for youth rather than graciously building up their self-esteem, stressing multicultural competence in an ever-shrinking world, encouraging and valuing education and skills training, increasing cooperative solutions to problems rather than competitive or aggressive solutions, and increasing a sense of responsibility for others and caring for others. Clearly, these are important objectives for creating the type of citizens that can make American strong in the twentieth century.

    2017-03-01

    The research emphasis has always been on sewerage treatment technology in China, though urban drainage system has gained little attention. In the context of urban drainage system and the problem associated with rain, the focus is still mainly toward the simple “emissions”. While the relationship between conservation and utilization of rainwater resources and urban ecology are popular, the relationship between rainwater discharge and non-point source pollution are often neglected. The reasonable choice of sewerage system is dependent on the collection and discharge of urban sewerage, the applicability and economic benefits, along with the ability to meet the water quality requirements and environmental protection. This paper analyzes and summarizes the development of urban drainage system in china, and introduces different drainage forms. The choice of drainage system should be based on the overall planning of the city, environmental protection requirements, the local natural conditions and water conditions, urban sewerage and water quality, the original drainage facilities, and local climatic conditions. It must be comprehensive to meet the environmental protection requirements, through technical and economic comparison.

    Nanomaterials have gained importance in various fields of science, technology, medicine, colloid technologies, diagnostics, drug delivery, personal care applications and others due to their small size and unique physico-chemical characteristic. Apart from above mentioned area, it is also extensively being used in food sector specifically in preservation and packaging. The future applications in food can also be extended to improve the shelf life, food quality, safety, fortification and biosensors for contaminated or spoiled food or food packaging. Different types and shapes of nanomaterials are being employed depending upon the need and nature of the food. Characterisation of these nanomaterials is essential to understand the interaction with the food matrix and also with biological compartment. This review is focused on application of nanotechnology in food industries. It also gives insight on commercial products in market with usage of nanomaterials, current research and future aspects in these areas. Currently, they are being incorporated into commercial products at a faster rate than the development of knowledge and regulations to mitigate potential health and environmental impacts associated with their manufacturing, application and disposal. As nanomaterials are finding new application every day, care should be taken about their potential toxic effects.

    2014-03-01

    This study aims to examine trends in studies of teens' health information behaviour. Eighty-two articles published between 2000 and 2012 were selected and analysed in various aspects: health topics by year, information sources, data collection methods, use of theories and models, collaborative and interdisciplinary efforts and published journals. Fifty-seven per cent of the studies focused on specific health topics, such as sexual health, while the rest covered general health topics. Almost half of the studies examined how teens search for and use health information on the Internet. Surveys were the most popular data collection technique. Only 12.2% were based on a theory or model. About 42% were conducted collaboratively by authors from multiple disciplines. With the increasing attention to specific health topics and online resources, the health information behaviour of teens has been examined more frequently since the mid-2000s. Its interdisciplinary nature was evidently shown from various disciplines that the authors were affiliated with and the journals of the published studies represented. This study suggests that there should be efforts to reflect new technology tools, apply mixed methods and increase the engagement level of collaboration to evolve this research domain. © 2014 The authors.

    Full Text Available Objectives This study aimed to investigate the current status of infectious disease research in North Korea by analyzing recent trends in medical journals from North Korea in comparison with research from South Korea. Methods Three medical journals (Preventive Medicine, Basic Medicine, and Chosun Medicine were analyzed from 2012 to 2016. Articles on tuberculosis (TB, malaria, and parasitic diseases were selected and classified by their subtopics and study areas. Two medical journals published in the South Korea were selected for a comparative analysis of research trends. Results Of the 2792 articles that were reviewed, 93 were extracted from North Korea journals. TB research in North Korea was largely focused on multi-drug resistant TB and extrapulmonary TB, whereas research in South Korea more frequently investigated non-tuberculous mycobacteria. Research on parasitic diseases in North Korea was focused on protozoan and intestinal nematodes, while the corresponding South Korea research investigated various species of parasites. Additionally, the studies conducted in North Korea were more likely to investigate the application of traditional medicine to diagnosis and treatment than those conducted in South Korea. Conclusions This study presents an analysis of research trends in preventive medicine in North Korea focusing on infectious diseases, in which clear differences were observed between South and North Korea. Trends in research topics suggest a high prevalence of certain parasitic diseases in North Korea that are no longer widespread in South Korea. The large proportion of studies examining traditional medicine implies a lack of affordable medicine in North Korea.

    Importance Advance care planning (ACP) may prevent end-of-life (EOL) care that is non-beneficial and discordant with patient wishes. Despite long-standing recognition of the merits of ACP in oncology, it is unclear whether cancer patients’ participation in ACP has increased over time. Objective To characterize trends in durable power of attorney (DPOA) assignment, living will creation, and participation in discussions of EOL care preferences, and to explore associations between ACP subtypes and EOL treatment intensity, as reflected in EOL care decisions and terminal hospitalizations. Design Prospectively collected survey data from the Health and Retirement Study (HRS), including data from in-depth “exit” interviews conducted with next-of-kin surrogates following the death of an HRS participant. Trends in ACP subtypes were tested, and multivariable logistic regression models examined associations between ACP subtypes and measures of treatment intensity. Setting HRS, a nationally representative, biennial, longitudinal panel study of U.S. residents over age 50. Participants 1,985 next-of-kin surrogates of HRS participants with cancer who died between 2000 and 2012. Main Outcome and Measures Trends in the surrogate-reported frequency of DPOA assignment, living will creation, and participation in discussions of EOL care preferences, as well as associations between ACP subtypes and surrogate-reported EOL care decisions/terminal hospitalizations. Results From 2000-2012, there was an increase in DPOA assignment (52% to 74%, p=0.03), without change in use of living wills (49% to 40%, p=0.63) or EOL discussions (68% to 60%, p=0.62). Surrogates increasingly reported that patients received “all care possible” at EOL (7% to 58%, p=0.004), and rates of terminal hospitalizations were unchanged (29% to 27%, p=0.70). Both living wills and EOL discussions were associated with limiting/withholding treatment [living will: adjusted odds ratio (AOR)=2.51, 95% confidence

The HRS is a nationally representative, biennial, longitudinal panel study of US residents older than 50 years. Trends in ACP subtypes were tested, and multivariable logistic regression models examined for associations between ACP subtypes and measures of treatment intensity. Trends in the surrogate-reported frequency of DPOA assignment, living will creation, and participation in discussions of EOL care preferences; associations between ACP subtypes and both surrogate-reported EOL care decisions and terminal hospitalizations. From 2000 to 2012, there was an increase in DPOA assignment (52% to 74%, P = .03), without significant change in use of living wills (49% to 40%, P = .63) or EOL discussions (68% to 60%, P = .62). Surrogate reports that patients received "all care possible" at EOL increased during the period (7% to 58%, P = .004), and rates of terminal hospitalizations were unchanged (29% to 27%, P = .70). Limiting or withholding treatment was associated with living wills (adjusted odds ratio [AOR], 2.51; 95% CI, 1.53-4.11; P EOL discussions (AOR, 1.93; 95% CI, 1.53-3.14; P = .002) but not with

    Full Text Available Focusing on four themes in relation to biodiversity (vegetation science, keystone grazers, long-term studies and protected areas, a synthesis of current research in the mountain areas of Fennoscandia, Iceland and Scotland is presented. Recent relevant advances in vegetation science include classifications of mountain habitats which together with species distribution maps offer new possibilities for analysis. Generalisations emerging from comparisons of the ecology and ecophysiology of plants between different mountain areas are greatly needed. Further studies on the ecological impacts of keystone grazers are urgently required because of the alarming rate of degradation of mountain habitats. The topics highlighted from northern Fennoscandia include (i the effect of overgrazing by reindeer on the cover of foliose lichens and on the regeneration of mountain birch, (ii the ecological interactions between the autumnal moth and mountain birch, and (Hi the effect of rodents on vegetation. Long-term studies of slow processes to capture rare but important events are needed to better understand the functioning of mountain ecosystems. Examples of such studies are presented for (i the moss Racomitrium lanuginosum as an indicator of airborne nitrogen pollution, (ii research based on cyclic oscillations of vole numbers, and (Hi the application of breeding birds in environmental assessment. The conservation of appropriate areas is important for mountain biodiversity. Mountain habitats have been protected extensively in northern Europe. The evaluation of how representative the existing areas are and how to use them for research need international co-ordination.

    Two independent cross-sectional dietary surveys (the Individual and National Food Consumption Surveys, INCA), performed in 1998-99 (INCA1) and in 2006-07 (INCA2) on nationally representative samples of French people, were used to analyse trends in the dietary habits and nutritional intake of French adults. Food consumption was recorded through 7-d dietary records, and nutritional intakes were assessed using the French food composition database. After exclusion of under-reporters, analyses were performed on 3267 adults, aged 18-79 years: 1345 from INCA1 and 1922 from INCA2. The trends highlighted over the 8-year period showed a decrease in consumption of dairy products, meat, bread, potatoes, pastries/croissant-like pastries/cakes/biscuits and sugar/confectionery. In contrast, the consumption of fruits and vegetables, rice, ice cream and chocolate increased. Other food groups, like fish and snacking foods, remained stable. Food choices were mostly age specific. These age differences remained consistent over the years and underlined two opposite dietary trends: a 'traditional' one mainly followed by the elderly, and a 'snacking and convenience' one mainly adopted by young adults. The overall trends in food consumption did not influence the mean energy intake, but did slightly modify the contribution of each macronutrient to energy intake. These repeated surveys highlighted the fact that trends in French food habits have moved towards an average European diet at the crossroads between Mediterranean and Northern diets, and that food consumption changes impacted, to a lesser extent, nutritional intake.

    Gender representation in Islamic bioethics research in the twenty-first century has not been studied. To study temporal trends in representation of female subjects in Islamic bioethics research, PubMed-listed publications on Islamic bioethics from years 2000 to 2014 were reviewed for gender participation in human subjects' research. There were temporal trends of increasing publications of Islamic bioethics-related human subjects' research (64 papers over 15 years; R 2  = 0.72; p < 0.0004). Female subjects were well represented with a trend toward increasing participation. This was true for women from Muslim-majority countries even in non-gender-focused studies over the past 15 years.

Objective To assess mass media exposure and it’s changing trends in Bangladesh using data from the Bangladesh Demographic and Health Survey (BDHS from 1993- 94 to 2014. Methods The study used data from the published reports of Bangladesh Demographic and Health Surveys (BDHS 1993-1994 to BDHS 2014. Results In the years of 1999-2000, 2004, 2007, 2014 women aged 20-24 years (41%, 54%, 56%, 57% respectively have passed more time watching television in weekly basis than the other age groups. Higher percentage was observed among the educated women than uneducated from 1999-2000 to 2014 who has made access to all three media (television, radio and newspaper at least once a week. Proportion of women who had accessed all three media at least once a week was much higher in the highest quintile families than the lowest quintile families and more exposure in urban women than the rural women. The region-wise coverage was higher in 1999-2000 in case of Chittagong (5.2%, Dhaka (4.7%, Khulna (5.1%, Rajshahi (3.1%, and Sylhet (3.9% division with access to all three media at least once a week except Barisal division. Conclusion Findings show higher percentage of television watching tendency among comparatively more educated and economically flourished urban women. Therefore, the major policy challenge addressees the need for designing of communications strategies targeting the less privileged, rural and illiterate people who constitute the majority of population in Bangladesh.

    Full Text Available Through survey results, this study evaluated global trends’ effects on Turkish kitchen furniture production. The level of knowledge and difficulties of catching up with and implementing developmental trends in the Turkish kitchen furniture sector has been seen as having a structure equivalent to world standards because the level of material and technological development has been determined by four criteria: consumer demand, housing plans, technology inadequacy, and material inadequacy. According to the results, findings in this framework, consumer demand was most influential (45.4% in capturing and implementing enterprises’ trends. Evaluation results on kitchen furniture projects implemented by Turkish enterprises within the last 5 years showed that they mostly worked with models with one-lid views in cabinet-door applications (41.6%. As a result, world trends reflect the direct influence of Turkish kitchen furniture manufacturers on cabinet-door models and color preferences for kitchen units.

  4. Correlates of consumer trust in online health information: findings from the health information national trends survey.

    2011-01-01

    The past few decades have witnessed a dramatic increase in consumers seeking health information online. However, the quality of such information remains questionable, and the trustworthiness of online health information has become a hot topic, whereas little attention has been paid to how consumers evaluate online health information credibility. This study builds on theoretical perspectives of trust such as personal-capital-based, social-capital-based, and transfer-based, and it examines various correlates of consumer trust in online health information. The author analyzed the 2007 Health Information National Trends Survey data (N = 7,674). Results showed that consumer trust in online health information did not correlate with personal capital such as income, education, and health status. Social capital indicated by visiting social networking Web sites was not associated with trust in online health information either. Nevertheless, trust in online health information transferred from traditional mass media and government health agencies to the Internet, and it varied by such information features as easiness to locate and to understand. Age appeared to be a key factor in understanding the correlates of trust in online health information. Theoretical and empirical implications of the results are discussed.

    This study explored current physiotherapy practice trends for management of children who are overweight or obese. The professional needs of physiotherapists working with this population were also assessed, including the perceived need for physiotherapy clinical guidelines for prevention and management of children with obesity. A cross-sectional survey design was used, with questionnaires purposefully distributed through 13 key physiotherapy services throughout Australia. Snowball sampling resulted in completed questionnaires from 64 physiotherapists who provided services to children. Half (n=33, 52%) of respondents provided services specifically to overweight or obese children. Of those providing services, one-quarter had prior training specific to working with this population. Most used multi-disciplinary models (n=16, 76%) and provided under 5h of obesity-related services each week (n=29, 88%). Half (n=16, 49%) used body mass index as an outcome measure but more (n=25, 76%) used bodyweight. Only 14 (42%) assessed motor skills. The majority of respondents (n=57, 89%) indicated a need for physiotherapy guidelines to best manage overweight and obese children. Professional development priorities included: 'Educating children and families', 'Assessment methods' and 'Exercise prescription' for overweight and obese children. This data provides workforce intelligence to guide future professional training and inform development of clinical guidelines for physiotherapists in prevention and management of children with obesity and related chronic disease.

    As part of the SAGES Legacy Unifying Globulars and GalaxieS (SLUGGS) survey, we stack 1137 Keck DEIMOS (Deep Imaging Multi-Object Spectrograph) spectra of globular clusters from 10 galaxies to study their stellar populations in detail. The stacked spectra have median signal-to-noise ratios of ˜90 Å-1. Besides the calcium triplet, we study weaker sodium, magnesium, titanium and iron lines as well as the Hα and higher order Paschen hydrogen lines. In general, the stacked spectra are consistent with old ages and a Milky Way-like initial mass function. However, we see different metal line index strengths at fixed colour and magnitude, and differences in the calcium triplet-colour relation from galaxy to galaxy. We interpret this as strong evidence for variations in the globular cluster colour-metallicity relation between galaxies. Two possible explanations for the colour-metallicity relation variations are that the average ages of globular clusters vary from galaxy to galaxy or that the average abundances of light elements (i.e. He, C, N and O) differ between galaxies. Stacking spectra by magnitude, we see that the colours become redder and metal line indices stronger with brighter magnitudes. These trends are consistent with the previously reported `blue tilts' being mass-metallicity relations.

    Information technology involves a risk of privacy violation in providing easy access to confidential information,such as personal information and medical information through the Internet. In this study, we investigated medical information security to gain a better understanding of trends in research related to medical information security. We researched papers published on '의료정보' and 'medical information' in various Korean journals during a 10-year period from 2005 to 2015. We also analyzed these journal papers for each fiscal year; these papers were categorized into the areas of literature research and empirical research, and were further subdivided according to themes and subjects. It was confirmed that 48 papers were submitted to 35 academic journals. There were 33 (68.8%) literature review articles, and analysis of secondary data was not carried out at all. In terms of empirical research, 8 (16.7%) surveys and 7 (14.6%) program developments were studied. As a result of analyzing these papers according to the research theme by research method, 17 (35.4%) papers on laws, systems, and policies were the most numerous. It was found that among the literature research papers on medical personnel were the most common, and among the empirical research papers, research on experts in information protection and medical personnel were the most common. We suggest that further research should be done in terms of social perception, human resource development, and technology development to improve risk management in medical information systems.

  8. How well do regional or national Breeding Bird Survey data predict songbird population trends at an intact boreal site?

    2014-06-01

    Full Text Available A study to monitor boreal songbird trends was initiated in 1998 in a relatively undisturbed and remote part of the boreal forest in the Northwest Territories, Canada. Eight years of point count data were collected over the 14 years of the study, 1998-2011. Trends were estimated for 50 bird species using generalized linear mixed-effects models, with random effects to account for temporal (repeat sampling within years and spatial (stations within stands autocorrelation and variability associated with multiple observers. We tested whether regional and national Breeding Bird Survey (BBS trends could, on average, predict trends in our study area. Significant increases in our study area outnumbered decreases by 12 species to 6, an opposite pattern compared to Alberta (6 versus 15, respectively and Canada (9 versus 20. Twenty-two species with relatively precise trend estimates (precision to detect > 30% decline in 10 years; observed SE ≤ 3.7%/year showed nonsignificant trends, similar to Alberta (24 and Canada (20. Precision-weighted trends for a sample of 19 species with both reliable trends at our site and small portions of their range covered by BBS in Canada were, on average, more negative for Alberta (1.34% per year lower and for Canada (1.15% per year lower relative to Fort Liard, though 95% credible intervals still contained zero. We suggest that part of the differences could be attributable to local resource pulses (insect outbreak. However, we also suggest that the tendency for BBS route coverage to disproportionately sample more southerly, developed areas in the boreal forest could result in BBS trends that are not representative of range-wide trends for species whose range is centred farther north.

    Full Text Available Flowering plants consists of more than 300.000 species around the world, out of which a small percentage has been sufficiently investigated from phytochemical and biological activity aspects. Plant diversity of the Balkans is very rich, but still poorly investigated. The aim of this paper is survey of current status and trends in research of wild-growing aromatic plants from Central Balkans. Many aromatic plants are investigated from morphological, physiological, ecological, systematic and phytochemical aspects. However, traditionally used medicinal and aromatic plants can also be considered from applicative aspects, concerning their health effects, and from wide range of usage in cosmetics, and as food, agrochemical and pharmaceutical products. In order to achieve all planned objectives, following methodology has been applied: field research, taxonomic authentication and, comparative biologically assayed phytochemical investigations. The total herbal extracts, postdistillation waste (deodorized extracts, essential oils and individual compounds of some autochthonous plants have been considered as potential source of antibacterial, antifungal, anti-biofilm, antioxidant and cytotoxic agents. In this manuscript, composition of essential oils and extracts were evaluated in a number of species, from the Apiaceae, Lamiaceae, Rosaceae and Asteraceae families. Extracts which were rich in phenols mostly of flavonoids, often showed high antioxidant potential. Also, phenolic compounds identified in essential oils and extracts were mostly responsible for expected antimicrobial activity. Current worldwide demand is to reduce or, if possible, eliminate chemically synthesized food additives. Plant-produced compounds are becoming of interest as a source of more effective and safe substances than synthetically produced antimicrobial agents (as inhibitors, growth reducers or even inactivators that control growth of microorganisms. Many different pathogens have

    Google Trends is a novel, freely accessible tool that allows users to interact with Internet search data, which may provide deep insights into population behavior and health-related phenomena. However, there is limited knowledge about its potential uses and limitations. We therefore systematically reviewed health care literature using Google Trends to classify articles by topic and study aim; evaluate the methodology and validation of the tool; and address limitations for its use in research. PRISMA guidelines were followed. Two independent reviewers systematically identified studies utilizing Google Trends for health care research from MEDLINE and PubMed. Seventy studies met our inclusion criteria. Google Trends publications increased seven-fold from 2009 to 2013. Studies were classified into four topic domains: infectious disease (27% of articles), mental health and substance use (24%), other non-communicable diseases (16%), and general population behavior (33%). By use, 27% of articles utilized Google Trends for casual inference, 39% for description, and 34% for surveillance. Among surveillance studies, 92% were validated against a reference standard data source, and 80% of studies using correlation had a correlation statistic ≥0.70. Overall, 67% of articles provided a rationale for their search input. However, only 7% of articles were reproducible based on complete documentation of search strategy. We present a checklist to facilitate appropriate methodological documentation for future studies. A limitation of the study is the challenge of classifying heterogeneous studies utilizing a novel data source. Google Trends is being used to study health phenomena in a variety of topic domains in myriad ways. However, poor documentation of methods precludes the reproducibility of the findings. Such documentation would enable other researchers to determine the consistency of results provided by Google Trends for a well-specified query over time. Furthermore, greater

    Described herein are the FY 2000 results of the survey on the technological trends of utilizing the reactions with metals in a living body, noting the bio-processes effectively coping with the environmental problems. The effects of heavy metals on microorganisms have been investigated on the molecular biology level, but are not fully elucidated. Recently, the microorganisms capable of converting inorganic metal ions in water into the insoluble compounds have been known, leading to possibility of bioremediation to solve pollution by heavy metals, which have detrimental effects on human health. Heavy metals must be recovered, because they are not extinct by decomposition. The plant aided purification has been attracting attention to cope with heavy metals accumulated in soil. Application of bacteria-aided leaching, which is adopted as one ore smelting process, to the technologies for utilizing metals in a living body has been expected, because diversified activities of inanimate matters in extreme environments have been known. Recently, bio-machining of metals aided by Thiobacillus ferrooxidans, one species of independent nutrient bacteria capable of eating metals, has been developed to a potentially viable stage. (NEDO)

    Full Text Available Massive Open Online Courses (MOOCs have attracted a great deal of attention by higher education and private enterprises. MOOCs have evolved considerably since their emergence in 2008, all the while given rise to academic discussions on MOOC impact, design and reach. In an effort to understand MOOCs more comprehensively, this study analyzes theses and dissertations (N = 51 related to MOOCs and published between 2008 and 2015, identifying research trends from these academic documents. Theses and dissertations within this research scope were gathered through a comprehensive search in multiple academic databases. For the purposes of the study, the research employed a systematic review approach. In order to reveal trends in research themes, emphasize theoretical/conceptual backgrounds, research designs and models, first a document analysis was used to collect data and this was followed by a content analysis. Our research findings indicate that MOOC research is generally derived from education, engineering and computer science, as well as information and communication technology related disciplines. Qualitative methodology linked to a case study research model is most common, and the theoretical/conceptual backgrounds are usually distance education related. Remarkably, nearly half of the studies didn’t benefit from any theoretical or conceptual perspectives. In sum, this study presents an evaluation regarding research trends derived from MOOC theses and dissertations, and provides directions for future MOOC research.

    Summarizing the status of drugs in the market and examining the trend of drug research and development is important in drug discovery. In this study, we compared the drug targets and the market sales of the new molecular entities approved by the U.S. Food and Drug Administration from January 2000 to December 2009. Two networks, namely, the target-target and drug-drug networks, have been set up using the network analysis tools. The multi-target drugs have much more potential, as shown by the network visualization and the market trends. We discussed the possible reasons and proposed the rational strategies for drug research and development in the future.

    The past decade has seen several high-level events and documents committing to strengthening the field of health policy and systems research (HPSR) as a critical input to strengthening health systems. Specifically, they called for increased production, capacity to undertake and funding for HPSR. The objective of this paper is to assess the extent to which progress has been achieved, an important feedback for stakeholders in this field. Two sources of data have been used. The first is a bibliometric analysis to assess growth in production of HPSR between 2003 and 2009. The six building blocks of the health system were used to define the scope of this search. The second is a survey of 96 research institutions undertaken in 2010 to assess the capacity and funding availability to undertake HPSR, compared with findings from the same survey undertaken in 2000 and 2008. Both analyses focus on HPSR relevant to low-income and middle-income countries (LMICs). Overall, we found an increasing trend of publications on HPSR in LMICs, although only 4% were led by authors from low-income countries (LICs). This is consistent with findings from the institutional survey, where despite improvements in infrastructure of research institutions, a minimal change has been seen in the level of experience of researchers within LIC institutions. Funding availability in LICs has increased notably to institutions in Sub-Saharan Africa; nonetheless, the overall increase has been modest in all regions. Although progress has been made in both the production and funding availability for HPSR, capacity to undertake the research locally has grown at a much slower pace, particularly in LICs where there is most need for this research. A firm commitment to dedicate a proportion of all future funding for research to building capacity may be the only solution to turn the tide.

This is consistent with findings from the institutional survey, where despite improvements in infrastructure of research institutions, a minimal change has been seen in the level of experience of researchers within LIC institutions. Funding availability in LICs has increased notably to institutions in Sub-Saharan Africa; nonetheless, the overall increase has been modest in all regions. CONCLUSION: Although progress has been made in both the production and funding availability for HPSR, capacity to undertake the research locally has grown at a much slower pace, particularly in LICs where there is most need for this research. A firm commitment to dedicate a proportion of all future funding for research to building capacity may be the only solution to turn the tide.

    Cigarette smoking risk-reducing beliefs are ideas that certain health promoting behaviors (e.g., exercise) may mitigate the risks associated with smoking. The objective of this study was to describe smoking risk-reducing beliefs and the belief that quitting can reduce the harmful effects of smoking among the U.S. adult population and the associations between these beliefs, current smoking status, and sociodemographics. Data were from the Health Information National Trends Survey 4 (HINTS 4) Cycles 3 and 4 (2013-2014; N=6862). Descriptive analyses were conducted to examine bivariate associations among the quit smoking belief, smoking risk-reducing beliefs, and covariates. Weighted ordinal logistic regression models examined the adjusted associations between smoking status and sociodemographics, with quit smoking belief and risk-reducing beliefs. Eighty-two percent of the population reported that quitting cigarette smoking can help reduce the harmful effects of smoking a lot: former smokers and individuals with higher educational attainment were more likely to endorse this belief than never smokers and those with lower educational attainment. Many people endorsed smoking risk-reducing beliefs about exercise (79.3%), fruits and vegetables (71.8%), vitamins (67.2%), and sleep (68.5%). Former smokers were less likely to subscribe to these beliefs than never smokers. Vulnerable populations who may be most at risk of smoking attributable morbidity and mortality were more likely to endorse risk-reducing beliefs. Future studies are needed to better understand how risk-reducing beliefs are formed and if modifying these beliefs may help to reduce cigarette smoking in the U.S. Published by Elsevier Inc.

    BACKGROUND: Many gastroenterology (GI) trainees face a variety of barriers to stable employment and are finding it increasingly difficult to secure employment in their chosen field. OBJECTIVE: To elucidate factors that contribute to the burden of unemployment and underemployment, and to examine solutions that may remedy this growing problem in the field of GI. METHODS: A nationwide survey of current, incoming and recently graduated individuals of GI training programs in Canada was conducted. Trainees in pediatric GI programs and those enrolled in sub-specialty programs within GI were also included. RESULTS: The response rate was 62%, with 93% of respondents enrolled in an adult GI training program. Many (73%) respondents planned to pursue further subspecialty training and the majority (53%) reported concerns regarding job security after graduation as contributory factors. Only 35% of respondents were confident that they would secure employment within six months of completing their training. Regarding barriers to employment, the most cited perceived reasons were lack of funding (both from hospitals and provincial governments) and senior physicians who continue to practice beyond retirement years. Sixty-nine per cent perceived a greater need for career guidance and 49% believed there were too many GI trainees relative to the current job market in their area. Most residents had a contingency plan if they remained unemployed >18 months, which often included moving to another province or to the United States. CONCLUSION: GI trainees throughout Canada reported substantial concerns about securing employment, citing national retirement trends and lack of funding as primary barriers to employment. Although these issues are not easily modifiable, certain problems should be targeted including optimizing training quotas, tailoring career guidance to the needs of the population, and emphasizing credentialing and quality control in endoscopy.

    The purpose of this study was to identify trends for studies published in the Journal of Korean Academy of Nursing and journals published by member societies from inaugural issues to 2010. A total of 6890 studies were analyzed using descriptive statistics. Quantitative studies accounted for 83.6% while qualitative studies accounted for 14.4%. Most frequently used research designs were quasi-experimental (91.1%) for experimental research and survey (85.2%) for non-experimental research. Most frequent study participants were healthy people (35.8%), most frequent nursing interventions, nursing skills (53.5%), and 39.8% used knowledge, attitude and behavior outcomes for dependent variables. Most frequently used keyword was elderly. Survey studies decreased from 1991 to 2010 by approximately 50%, while qualitative studies increased by about 20%. True experimental research (1.2%) showed no significant changes. Studies focusing on healthy populations increased from 2001-2005 (37.5%) to 2006-2010 (41.0%). From 1970 to 2010, studies using questionnaire accounted for over 50% whereas physiological measurement, approximately 5% only. Experimental studies using nursing skill interventions increased from 1970-1980 (30.4%) to 2006-2010 (64.0%). No significant changes were noted in studies using knowledge, attitude and behavior (39.9%) as dependent variables. The results suggest that further expansion of true experimental, qualitative studies and physiological measurements are needed.

    This study quantified the potential reach of Internet smoking cessation interventions to support calculations of potential population impact (reach × effectiveness). Using a nationally representative survey, we calculated the number and proportion of adult smokers that look for cessation assistance online each year. Five waves (2005, 2011, 2013, 2015, 2017) of the National Cancer Institute's Health Information National Trends Survey were examined. The survey asked US adults whether they ever go online to use the Internet, World Wide Web, or email and had used the Internet to look for information about quitting smoking within the past 12 months. We estimated the proportion and number of (1) all US adult smokers, and (2) online US adult smokers that searched for cessation information online. Cross-year comparisons were assessed with logistic regression. The proportion of all smokers who searched online for cessation information increased over the past decade (p < .001): 16.5% in 2005 (95% CI = 13.2% to 20.4%), 20.9% in 2011 (95% CI = 15.55% to 28.0%), 25.6% in 2013 (95% CI = 19.7% to 33.0%), 23.4% in 2015 (95% CI = 16.9% to 31.0%), and 35.9% in 2017 (95% CI = 24.8% to 48.9%). Among online smokers only, approximately one third searched online for cessation information each year from 2005 through 2015. In 2017, that proportion increased to 43.7% (95% CI = 29.7% to 58.7%), when an estimated 12.4 million online smokers searched for cessation help. More than one third of all smokers turn to the Internet for help quitting each year, representing more than 12 million US adults. This research provides contemporary estimates for the reach of Internet interventions for smoking cessation. Such estimates are necessary to estimate the population impact of Internet interventions on quit rates. The research finds more than 12 million US smokers searched online for cessation information in 2017.

    Basic research results can provide new ideas and hypotheses to be examined in epidemiological studies. We conducted a survey among testicular cancer researchers on hypotheses concerning the etiology of this malignancy. All researchers on the mailing list of Copenhagen Testis Cancer Workshops and corresponding authors of PubMed-indexed articles identified by the search term 'testicular cancer' and published within 10 years (in total 2750 recipients) were invited to respond to an e-mail-based survey. Participants of the 8th Copenhagen Testis Cancer Workshop in May 2014 were subsequently asked to rate the plausibility of the suggested etiologic hypotheses on a scale of 1 (very implausible) to 10 (very plausible). This report describes the methodology of the survey, the score distributions by individual hypotheses, hypothesis group, and the participants' major research fields, and discuss the hypotheses that scored as most plausible. We also present plans for improving the survey that may be repeated at a next international meeting of experts in testicular cancer. Overall 52 of 99 (53%) registered participants of the 8th Copenhagen Testis Cancer Workshop submitted the plausibility rating form. Fourteen of 27 hypotheses were related to exposures during pregnancy. Hypotheses with the highest mean plausibility ratings were either related to pre-natal exposures or exposures that might have an effect during pregnancy and in post-natal life. The results of the survey may be helpful for triggering more specific etiologic hypotheses that include factors related to endocrine disruption, DNA damage, inflammation, and nutrition during pregnancy. The survey results may stimulate a multidisciplinary discussion about new etiologic hypotheses of testicular cancer. Published 2014. This article is a U. S.

    Millions of people use online search engines everyday to find health-related information and voluntarily share their personal health status and behaviors in various Web sites. Thus, data from tracking of online information seeker's behavior offer potential opportunities for use in public health surveillance and research. Google Trends is a feature of Google which allows Internet users to graph the frequency of searches for a single term or phrase over time or by geographic region. We used Google Trends to describe patterns of information-seeking behavior in the subject of dense breasts and to examine their correlation with the passage or introduction of dense breast notification legislation. To capture the temporal variations of information seeking about dense breasts, the Web search query "dense breast" was entered in the Google Trends tool. We then mapped the dates of legislative actions regarding dense breasts that received widespread coverage in the lay media to information-seeking trends about dense breasts over time. Newsworthy events and legislative actions appear to correlate well with peaks in search volume of "dense breast". Geographic regions with the highest search volumes have passed, denied, or are currently considering the dense breast legislation. Our study demonstrated that any legislative action and respective news coverage correlate with increase in information seeking for "dense breast" on Google, suggesting that Google Trends has the potential to serve as a data source for policy-relevant research.

    This paper reports the research results on the present state and future trend of protective measures for the ozone layer, and the trend of preventive measures against global warming by substituting CFCs such as HFC, through international conferences, meetings and lecture meetings, and literature survey. In the 8th meeting of the parties to the Montreal Protocol, it was presented that refrigerator producers in Thailand phased out CFCs from their products earlier than the schedule in cooperation with Japan. The final draft including the approval of essential use from 1997 to 2002 was reviewed, and reported to the technology/economy assessment panel. Reduction of ozone depleting substances was guided in Thailand, Indonesia and Philippines. The latest trend of substituting technologies of HCFC was surveyed, and the control trend of F-containing greenhouse effect gas emission was also surveyed through the conference of the parties of climate change in fiscal 1996. Based on the IPCC report in 1995, the emission amount of greenhouse gases of nearly 10% in contribution such as CO2, methane and fluorocarbon was arranged. R and D on destruction of CFCs was also surveyed. 35 refs., 54 figs., 32 tabs.

    Background: Although more and more women are becoming physicians, their decisions regarding pregnancy may be affected by the lengthy period of medical education and postgraduate training. The aim of this study was to explore the birth trends among female physicians in Taiwan; Methods: Retrospective analyses of maternal ages at delivery from 1996 to 2013, both for physicians and the general population, were conducted using a nationwide dataset called National Health Insurance Research Database; Results: During the study period, 8540 female physicians were identified. The physicians delivered a total of 4940 births in that time, with a rise from 210 in 1996 to 440 in 2013. In addition, the mean maternal age of the physicians at delivery increased from 32.19 years (standard deviations (SD) 2.80) in 1996 to 33.61 (SD 3.21) in 2013, values significantly higher than those for non-physicians of 27.81 (SD 4.74) in 1996 (p < 0.001) and 31.36 (SD 4.78) in 2013 (p < 0.001); Conclusion: Female physicians usually gave birth at an older age than non-physicians, but the discrepancy between the two groups gradually declined over the 18-year course of the study. The establishment of a maternity-friendly environment for female physicians should be considered by those who determine healthcare system policies. PMID:28698490

    Full Text Available Abstract Background Healthcare acquired infections (HAI are an important public health problem in developed countries, but comprehensive data on trends over time are lacking. Prevalence surveys have been used as a surrogate for incidence studies and can be readily repeated. Methods The Canadian Nosocomial Infection Surveillance Program conducted prevalence surveys in 2002 and 2009 in a large network of major Canadian acute care hospitals. NHSN definitions of HAI were used. Use of isolation precautions on the survey day was documented. Results In 2009, 9,953 acute care inpatients were surveyed; 1,234 infections (124/1000 were found, compared to 111/1000 in 2002, (p < 0.0001. There was increased prevalence of urinary tract infection (UTI and Clostridium difficile, offset by decreases in pneumonia and bloodstream infection. Use of isolation precautions increased from 77 to 148 per 1000 patients (p < 0.0001, attributable to increased use of contact precautions in patients infected or colonized with antimicrobial resistant organisms. Conclusion Between 2002 and 2009 HAI prevalence increased by 11.7 % in a network of major Canadian hospitals due to increases in Clostridium difficile and urinary tract infection. The use of isolation precautions increased by 92.2 % attributable to increased contact isolation. National prevalence surveys are useful tools to assess evolving trends in HAI.

    For over a century, the discontinuation of oral food intake preoperatively after midnight has been routinely applied. Although routine fasting during the night before elective surgery has been abandoned by many modern centers, preoperative fasting after midnight continues as a routine practice. The purpose of this study was to determine trends in health personnel's application of new guidelines for preoperative fasting. The research sample of this descriptive study consisted of 73 nurses and physicians who were working in the surgical clinics during the time when the study was conducted and who agreed to participate in the study. The data of the study were collected using a questionnaire designed by the researchers. Of the health personnel included in the study group, 43.8% routinely kept adult patients fasting after midnight, 34.2% discontinued solid food intake 8 hours preoperatively, 5.5% discontinued solid food intake 6 hours preoperatively, and 34.2% discontinued the intake of clear and particulate liquids 4 to 8 hours preoperatively. Compliance of the American Society of Anesthesiologists' "2-4-6-8 rule" by health staff was very low. This study was carried out in a hospital and based on the statements of health staff. Therefore, the findings of the study are suggestive in nature and cannot be generalized. We recommend that the study should be conducted with larger sample groups and that actual preoperative fasting periods of the patients should be determined.

    2015-01-01

    The aim of this study is to analyze the research trends of medical informatics over the last 12 years. A new method based on MeSH terms was proposed to identify emerging topics and trends of medical informatics research. Informetric methods and visualization technologies were applied to investigate research trends of medical informatics. The metric of perspective factor (PF) embedding MeSH terms was appropriately employed to assess the perspective quality for journals. The emerging MeSH terms have changed dramatically over the last 12 years, identifying two stages of medical informatics: the "medical imaging stage" and the "medical informatics stage". The focus of medical informatics has shifted from acquisition and storage of healthcare data by integrating computational, informational, cognitive and organizational sciences to semantic analysis for problem solving and clinical decision-making. About 30 core journals were determined by Bradford's Law in the last 3 years in this area. These journals, with high PF values, have relative high perspective quality and lead the trend of medical informatics.

  10. An Examination of Growing Trends in Land Tenure and Conservation Practice Adoption: Results from a Farmer Survey in Iowa

    2016-02-01

    Tenants and part-owners are farming an increasing number of acres in the United States, while full-owners are farming fewer acres. This shift in ownership is a potential cause for concern because some previous research indicated that tenant and part-owner farmers were less likely to adopt conservation practices than farmers who owned the land they farmed. If that trend persists, ownership changes would signal a national drop in conservation adoption. Here we examine this issue using a survey of agricultural operators in the Clear Creek watershed in Iowa, a state with intensive agricultural production. We compare adoption of conservation practices, and preferences for conservation information sources and communication channels, between farmers who rent some portion of the land they farm (tenants and part-owners) and farmers who own all of the land they farm (full-owners). We find that renters are more likely to practice conservation tillage than full-owners, though they are less likely to rotate crops. In addition, renters report using federal government employees (specifically, Natural Resource Conservation Service and Farm Service Agency) as their primary sources of conservation information, while full-owners most frequently rely on neighbors, friends, and County Extension. These findings are significant for conservation policy because, unlike some past research, they indicate that renters are not resistant to all types of conservation practices, echoing recent studies finding an increase in conservation adoption among non-full-owners. Our results emphasize the importance of government conservation communication and can inform outreach efforts by helping tailor effective, targeted conservation strategies for owners and renters.

    Recently, construction safety management (CSM) practices and systems have become important topics for stakeholders to take care of human resources. However, few studies have attempted to map the global research on CSM. A comprehensive bibliometric review was conducted in this study based on multiple methods. In total, 1172 CSM-related papers from the Web of Science Core Collection database were examined. The analyses focused on publication year, country-institute, publication source, author and research topics. The results indicated that the USA, China, Australia and the UK took leading positions in CSM research. Two branches of journals were identified, namely the branch of engineering science and that of safety science and social science. Additionally, seven themes together with 28 specific topics were detected to allow researchers to track the main structure and temporal evolution of CSM research. Finally, the main research trends and potential research directions were discussed to guide the future research.

    The exposure doses of patients in X-ray photography are influenced by such technological factors as X-ray tube voltage, filter, sensitizing screen, film and grid. Survey by questionnnaire was made previously in 1973 on the above factors. The trends five years after were surveyed similarly, in connection with the exposure doses of patients. Questionnaires were sent to 200 radiation technicians, and 121 (60.5%) answered the survey in March, 1979. The results in the cases of simple X-ray photography and obstetric, infant and breast X-ray photographings are described. X-ray tube voltage is generally on the increase. In the sensitizing screens, exposure doses are fairly decreased due to the use of improved intensifying screen (LT-II). In the grid, the ratio 8 : 1 is used more than 5 : 1. In the usage of additional filters and in the distance of photography, improvements are desired.

    Evaluation studies of population-based tobacco control interventions often rely on large-scale survey data from numerous respondents across many geographic areas to provide evidence of their effectiveness. Significant challenges for survey research have emerged with the evolving communications landscape, particularly for surveying hard-to-reach populations such as youth and young adults. This study combines the comprehensive coverage of an address-based sampling (ABS) frame with the timeliness of online data collection to develop a nationally representative longitudinal cohort of young people aged 15-21. We constructed an ABS frame, partially supplemented with auxiliary data, to recruit this hard-to-reach sample. Branded and tested mail-based recruitment materials were designed to bring respondents online for screening, consent and surveying. Once enrolled, respondents completed online surveys every 6 months via computer, tablet or smartphone. Numerous strategies were utilized to enhance retention and representativeness RESULTS: Results detail sample performance, representativeness and retention rates as well as device utilization trends for survey completion among youth and young adult respondents. Panel development efforts resulted in a large, nationally representative sample with high retention rates. This study is among the first to employ this hybrid ABS-to-online methodology to recruit and retain youth and young adults in a probability-based online cohort panel. The approach is particularly valuable for conducting research among younger populations as it capitalizes on their increasing access to and comfort with digital communication. We discuss challenges and opportunities of panel recruitment and retention methods in an effort to provide valuable information for tobacco control researchers seeking to obtain representative, population-based samples of youth and young adults in the U.S. as well as across the globe. © Article author(s) (or their employer

    2017-01-01

    This article analyses the history of the European Social Survey (ESS) and its relationship to changes in European research policy, using Bourdieu’s field-analytical approach. It argues that the success of the ESS relied on three interwoven processes that we can understand theoretically in terms...... of the establishment of homological structures and the formation of conjunctural alliances between the field of European social-scientific research and the field of European policy. The three interwoven processes that I depict are: first, the production of a European field of social research, connected to both...... European and national scientific institutions; second, the establishment of European Union (EU) institutions and organisations that were able to identify and link up with social researchers; and third, the formation of conjunctural alliances between the two fields (social science and EU research policy...

  20. The use of U.S. Geological Survey digital geospatial data products for science research

    Varanka, Dalia E.; Deering, Carol; Caro, Holly

    2012-01-01

    The development of geographic information system (GIS) transformed the practice of geographic science research. The availability of low-cost, reliable data by the U.S. Geological Survey (USGS) supported the advance of GIS in the early stages of the transition to digital technology. To estimate the extent of the scientific use of USGS digital geospatial data products, a search of science literature databases yielded numbers of articles citing USGS products. Though this method requires careful consideration to avoid false positives, these citation numbers of three types of products (vector, land-use/land-cover, and elevation data) were graphed, and the frequency trends were examined. Trends indicated that the use of several, but not all, products increased with time. The use of some products declined and reasons for these declines are offered. To better understand how these data affected the design and outcomes of research projects, the study begins to build a context for the data by discussing digital cartographic research preceding the production of mass-produced products. The data distribution methods used various media for different system types and were supported by instructional material. The findings are an initial assessment of the affect of USGS products on GIS-enabled science research. A brief examination of the specific papers indicates that USGS data were used for science and GIS conceptual research, advanced education, and problem analysis and solution applications.

    2017-10-12

    Smart Healthcare is a relatively new context-aware healthcare paradigm influenced by several fields of knowledge, namely medical informatics, communications and electronics, bioengineering, ethics and so on. Thus, many challenging problems are related to smart healthcare but in many cases they are explored individually in their respective fields and, as a result, they are not always known by the smart healthcare research community working in more specific domains. The aim of this article is to identify some of the most relevant trends and research lines that are going to affect the smart healthcare field in the years to come. To do so, the article considers a systematic approach that classifies the identified research trends and problems according to their appearance within the data life cycle, this is, from the data gathering in the physical layer (lowest level) until their final use in the application layer (highest level). By identifying and classifying those research trends and challenges, we help to pose questions that the smart healthcare community will need to address. Consequently, we set a common ground to explore important problems in the field, which will have significant impact in the years to come.

    1991-09-01

    This report documents the results of a survey of domestic research on superconducting magnetic energy storage (SMES) undertaken with the support of the Oak Ridge National Laboratory (ORNL) Superconductivity Pilot Center. Each survey entry includes the following: Name, address, and other telephone and facsimile numbers of the principal investigator and other staff members; funding for fiscal year 1991, 1992, 1993; brief descriptions of the program, the technical progress to date, and the expected technical progress; a note on any other collaboration. Included with the survey are recommendations intended to help DOE decide how best to support SMES research and development (R ampersand D). To summarize, I would say that important elements of a well-rounded SMES research program for DOE are as follows. (1) Construction of a large ETM. (2) Development of SMES as an enabling technology for solar and wind generation, especially in conjunction with the ETM program, if possible. (3) Development of small SMES units for electric networks, for rapid transit, and as noninterruptible power supplies [uses (2), (3), and (4) above]. In this connection, lightweight, fiber-reinforced polymer structures, which would be especially advantageous for space and transportation applications, should be developed. (4) Continued study of the potential impacts of high-temperature superconductors on SMES, with construction as soon as feasible of small SMES units using high-temperature superconductors (HTSs)

    To survey US-trained graduating neurology residents who are American Academy of Neurology members, in an effort to trend perceived quality and completeness of graduate neurology education. An electronic survey was sent to all American Academy of Neurology members graduating from US neurology residency programs in the Spring of 2014. Of 805 eligible respondents, 24% completed the survey. Ninety-three percent of adult neurology residents and 56% of child neurology residents reported plans to pursue fellowship training after residency. Respondents reported a desire for additional training in neurocritical care, neuro-oncology, neuromuscular diseases, botulinum toxin injection, and nerve blocks. There remains a clear deficit in business training of neurology residents, although there was notable improvement in knowledge of coding and office management compared to previous surveys. Although there are still areas of perceived weakness in neurology training, graduating neurology residents feel generally well prepared for their chosen careers. However, most still pursue fellowship training for reasons that are little understood. In addition to certain subspecialties and procedures, practice management remains deficient in neurology training and is a point of future insecurity for most residents. Future curriculum changes should consider resident-reported gaps in knowledge, with careful consideration of improving business training. © 2016 American Academy of Neurology.

    Objective The purpose of this paper was to examine trends in the use of premium and discount cigarette brands and determine correlates of type of brand used and brand switching. Methods Data from the International Tobacco Control (ITC) US adult smoker cohort survey were analyzed. The total study sample included 6669 adult cigarette smokers recruited and followed from 2002 to 2011 over eight different survey waves. Each survey wave included an average of 1700 smokers per survey with replenishment of those lost to follow-up. Results Over the eight survey waves, a total of 260 different cigarette brands were reported by smokers, of which 17% were classified as premium and 83% as discount brands. Marlboro, Newport, and Camel were the most popular premium brands reported by smokers in our sample over all eight survey waves. The percentage of smokers using discount brands increased between 2002 and 2011, with a marked increase in brand switching from premium to discount cigarettes observed after 2009 corresponding to the $0.61 increase in the federal excise tax on cigarettes. Cigarette brand preferences varied by age group and income levels with younger, higher income smokers more likely to report smoking premium brand cigarettes, while older, middle and lower income, heavier smokers were more likely to report using discount brands. Conclusions Our data suggest that demographic and smoking trends favor the continued growth of low priced cigarette brands. From a tobacco control perspective, the findings from this study suggest that governments should consider enacting stronger minimum pricing laws in order to keep the base price of cigarettes high, since aggressive price marketing will likely continue to be used by manufacturers to compete for the shrinking pool of remaining smokers in the population.

    Ganong, Lawrence

    2011-11-01

    This article reviews family nursing research published from 1996 to 2011. This is a follow-up to a review published in the Journal of Family Nursing in 1995. Findings from the first review are compared with this one, trends in family nursing scholarship are identified, and predictions and suggestions for future directions are offered. The latest generation of family nursing scholarship is conceptually and methodologically sound, and there is evidence of more multidisciplinary and interdisciplinary research conducted by family nursing researchers. Scholars are paying more attention to issues of diversity and family context at present than in the past, although there are still aspects of diversity that need more attention. Strong research programs in family nursing exist worldwide; an international synergism has helped promote rapid expansion of family nursing research and theory development. A vigorous movement to promote research to practice initiatives and greater attention to family interventions are exciting developments.

    This descriptive study evaluated behavioral and social science research on sport for 1993 through 2008, examined the characteristics of sport research, and identified mainstream issues appearing during these 16 years. Based on the Social Science Citation Index (SSCI) database from 1993 to 2008, 7,655 articles referring to sport or sports were available. The publication analyses showed that 13 core journals published the most articles in the behavioral sciences of sport. By analyzing all titles, author keywords, and KeyWords Plus, the results showed that physical education, athlete performance, and sports participation were the mainstream issues of sport research in the 16-year study period. The words adolescent, youth, and children frequently appeared, indicating that the emphasis of sport research focused on these participant groups. This bibliometric study reviewed global sports research in SSCI, and described certain patterns or trends in prior research on sport.

    Full Text Available Orientation: A comprehensive framework for research in human resource management (HRM in terms of fundamental knowledge orientations was found lacking. Research purpose: The aim was to perform a typological review of research trends in the field of HRM, specifically of publications in the South African Journal of Human Resource Management (SAJHRM. Motivation for the study: No previous research in the field of HRM in South Africa adopted a fundamental theory of knowledge. Research design, approach and method: A qualitative design was followed, consisting of a documentary analysis of articles that were published in the SAJHRM for the period from 2003 to 2015. A detailed content analysis of published articles was performed in terms of a number of criteria, namely knowledge type, race, gender, authorship, author contribution and representation according to author institution and country of origin. Main findings: An analysis of a final selection of 289 articles indicated that research in the SAJHRM was mostly on the following lines: research was mostly of the hypothesis-testing (Type II knowledge type; involved multiple authorship; and was conducted by mostly white, male researchers, based at a relatively few South African academic institutions. Practical and managerial implications: The SAJHRM should, in partnership with the HRM profession, promote and publish research that more prominently addresses the gap between academic HRM and HRM practice, especially in terms of the participatory or action research (Type IV mode of knowledge generation. Contribution: The present analysis of research trends in the SAJHRM provides a broader and more nuanced perspective on forms of research required for the HRM field in South Africa.

  2. Trends and problems in marital and family therapy research: Possible use of action research

    2006-03-01

    Full Text Available Although research in marital and family therapy (MFT is becoming increasingly important, it continues to encounter several major problems. Studies have shown that research has very little influence on the practice of the majority of MFT practitioners. Practitioners see research as unrelated to their concerns. The practice of the majority of MFT practitioners is very individualized, as are the clinical problems and circumstances. Some have therefore started to emphasize the transferability of results instead of generalizability, and studying the practitioner's own practice instead of general concepts. Action research in the field of psychotherapy, as well as in the field of MFT, has been mainly overlooked as a potential method for solving these problems in MFT research. The paper addresses one of many possible ways to use the repeating cycles of the four basic steps in action research (observing and gathering information, reflecting, planning, and acting. The use of these four steps in action research enables therapists to study and improve their own practice in a more systematic, structured, and valid manner. This kind of research connects research and therapy. It is very individualized and oriented towards actions that create therapeutic changes.

    2016-04-01

    The goal of this study was to understand research trends and collaboration patterns together with scholarly impact within the domain of global obesity research. We developed and analysed bibliographic affiliation data collected from 117,340 research articles indexed in Scopus database on the topic of obesity and published from 1993-2012. We found steady growth and an exponential increase of publication numbers. Research output in global obesity research roughly doubled each 5 years, with almost 80% of the publications and authors from the second decade (2003-2012). The highest publication output was from the USA - 42% of publications had at least one author from the USA. Many US institutions also ranked highly in terms of research output and collaboration. Fifteen of the top-20 institutions in terms of publication output were from the USA; however, several European and Japanese research institutions ranked more highly in terms of average citations per paper. The majority of obesity research and collaboration has been confined to developed countries although developing countries have showed higher growth in recent times, e.g. the publication ratio between 2003-2012 and 1993-2002 for developing regions was much higher than that of developed regions (9:1 vs. 4:1). We also identified around 42 broad disciplines from authors' affiliation data, and these showed strong collaboration between them. Overall, this study provides one of the most comprehensive longitudinal bibliometric analyses of obesity research. This should help in understanding research trends, spatial density, collaboration patterns and the complex multi-disciplinary nature of research in the obesity domain. © 2016 World Obesity.

    Full Text Available This study intends to explore the current trends in the field of distance education research during the period of 2009-2013. The trends were identified by an extensive review of seven peer reviewed scholarly journals: The American Journal of Distance Education (AJDE, Distance Education (DE, The European Journal of Open, Distance and e-Learning (EURODL, The Journal of Distance Education (JDE, The Journal of Online Learning and Technology (JOLT, Open Learning: The Journal of Open, Distance and e-Learning (OL and The International Review of Research in Open and Distributed Learning (IRRODL. A total of 861 research articles was reviewed. Mainly content analysis was employed to be able to analyze the current research. Also, a social network analysis (SNA was used to interpret the interrelationship between keywords indicated in these articles. Themes were developed and the content of the articles in the selected journals were coded according to categories derived from earlier studies. The results were interpreted using descriptive analysis (frequencies and social network analysis. The reporting of the results were organized into the following categories: research areas, theoretical and conceptual frameworks, variables, methods, models, strategies, data collection and analysis methods, and the participants. The study also identified the most commonly used keywords, and the most frequently cited authors and studies in distance education. The findings obtained in this study may be useful in the exploration of potential research areas and identification of neglected areas in the field of distance education.

    This aim of this study is to examine trends in medical education research in the Korean Journal of Medical Education(KJME) and suggest improvements for medical education research. The main variables were keywords from research papers that were published in KJME. Abstracts of papers (n=499) that were published from 1991 through 2015 were analyzed by social network analysis (NetMiner 4.0) a common research methodfor trends in academic subjects. The most central keywords were "medical education," "clinical competence," "medical student," and "curriculum." After introduction into graduate medical school, newly appearing keywords were "professional behavior," "medical humanities," "communication,"and "physician-patient relation." Based on these results, we generated a schematic of the network, in which the five groups before introduction to graduate medical school expanded to nine groups after introduction. Medical education research has been improving qualitatively and quantitatively, and research subjects have been expanded, subdivided, and specific. While KJME has encompassed medical education studies comprehensively, studies on medical students have risen in number. Thus, the studies that are published in KJME were consistent with the direction of journal and a new study on the changes in medical education is being conducted.

    To assess nursing staff's background and research and quality improvement (QI) experience. In this corporation, participation in research and QI is encouraged, but little is known about nurses' experiences. A web-based survey was distributed. Nursing staffs from an academic/teaching medical centre and other intra-corporation non-academic facilities were compared. Respondents included: 148 (52.9%) medical centre and 132 (47.1%) non-medical centre subjects. Medical centre respondents had a higher proportion previously engaged in research, currently engaged in research and previously engaged in QI. Productivity (grant, published and presented) was low for both groups but statistically lower for the non-medical centre group. Medical centre employees used research resources more often than the non-medical centre. Time was the most frequently mentioned barrier to participation in research and QI initiatives. A moderate proportion of respondents had research and QI experience, yet productivity and use of resources was low. Nurses at non-academically focused facilities were in most need of assistance. Familiarizing nurses with resources and providing protected time may increase productivity. Developing an infrastructure to support nursing research is a worthy goal. Information about interest and experience of nurses can aid management in determining how to focus financial resources. © 2011 The Authors. Journal compilation © 2011 Blackwell Publishing Ltd.

  11. Research trends on Big Data in Marketing: A text mining and topic modeling based literature analysis

    2018-01-01

    Full Text Available Given the research interest on Big Data in Marketing, we present a research literature analysis based on a text mining semi-automated approach with the goal of identifying the main trends in this domain. In particular, the analysis focuses on relevant terms and topics related with five dimensions: Big Data, Marketing, Geographic location of authors’ affiliation (countries and continents, Products, and Sectors. A total of 1560 articles published from 2010 to 2015 were scrutinized. The findings revealed that research is bipartite between technological and research domains, with Big Data publications not clearly aligning cutting edge techniques toward Marketing benefits. Also, few inter-continental co-authored publications were found. Moreover, findings show that research in Big Data applications to Marketing is still in an embryonic stage, thus making it essential to develop more direct efforts toward business for Big Data to thrive in the Marketing arena.

    To conduct a trend analysis of Pap test practices, Pap test results and related women's services and guidelines of college health centers. College health centers who participated in the annual ACHA Pap Test and STI (sexually transmitted infection) Survey years 2004-2014 (n ranged from 127 to 181 depending on year). Descriptive analyses are presented with ANOVAs (Analysis of Variance) and chi-square tests calculated to examine trends over time. The number of Pap tests significantly decreased over time; however, the percentage of normal and HSIL (high-grade squamous intraepithelial lesion) results did not vary. Availability of conventional cytology slides and cryotherapy were significantly associated with year. Over time, college health centers' guidelines related to initiation of Pap testing evolved to consistently conform to national recommendations for cervical screening. The results indicate most college health centers are following the current national guidelines regarding Pap testing for young adult women.

    2012-02-01

    This study documented the trends in authorship and sampling in applied biomechanics research published in the Journal of Applied Biomechanics and ISBS Proceedings. Original research articles of the 1989, 1994, 1999, 2004, and 2009 volumes of these serials were reviewed, excluding reviews, modeling papers, technical notes, and editorials. Compared to 1989 volumes, the mean number of authors per paper significantly increased (35 and 100%, respectively) in the 2009 volumes, along with increased rates of hyperauthorship, and a decline in rates of single authorship. Sample sizes varied widely across papers and did not appear to change since 1989.

  14. Samples and data accessibility in research biobanks: an explorative survey

    2016-02-01

    Full Text Available Biobanks, which contain human biological samples and/or data, provide a crucial contribution to the progress of biomedical research. However, the effective and efficient use of biobank resources depends on their accessibility. In fact, making bio-resources promptly accessible to everybody may increase the benefits for society. Furthermore, optimizing their use and ensuring their quality will promote scientific creativity and, in general, contribute to the progress of bio-medical research. Although this has become a rather common belief, several laboratories are still secretive and continue to withhold samples and data. In this study, we conducted a questionnaire-based survey in order to investigate sample and data accessibility in research biobanks operating all over the world. The survey involved a total of 46 biobanks. Most of them gave permission to access their samples (95.7% and data (85.4%, but free and unconditioned accessibility seemed not to be common practice. The analysis of the guidelines regarding the accessibility to resources of the biobanks that responded to the survey highlights three issues: (i the request for applicants to explain what they would like to do with the resources requested; (ii the role of funding, public or private, in the establishment of fruitful collaborations between biobanks and research labs; (iii the request of co-authorship in order to give access to their data. These results suggest that economic and academic aspects are involved in determining the extent of sample and data sharing stored in biobanks. As a second step of this study, we investigated the reasons behind the high diversity of requirements to access biobank resources. The analysis of informative answers suggested that the different modalities of resource accessibility seem to be largely influenced by both social context and legislation of the countries where the biobanks operate.

  15. Hydrographic processing considerations in the “Big Data” age: An overview of technology trends in ocean and coastal surveys

    Holland, M.; Hoggarth, A.; Nicholson, J.

    2016-04-01

    The quantity of information generated by survey sensors for ocean and coastal zone mapping has reached the “Big Data” age. This is influenced by the number of survey sensors available to conduct a survey, high data resolution, commercial availability, as well as an increased use of autonomous platforms. The number of users of sophisticated survey information is also growing with the increase in data volume. This is leading to a greater demand and broader use of the processed results, which includes marine archeology, disaster response, and many other applications. Data processing and exchange techniques are evolving to ensure this increased accuracy in acquired data meets the user demand, and leads to an improved understanding of the ocean environment. This includes the use of automated processing, models that maintain the best possible representation of varying resolution data to reduce duplication, as well as data plug-ins and interoperability standards. Through the adoption of interoperable standards, data can be exchanged between stakeholders and used many times in any GIS to support an even wider range of activities. The growing importance of Marine Spatial Data Infrastructure (MSDI) is also contributing to the increased access of marine information to support sustainable use of ocean and coastal environments. This paper offers an industry perspective on trends in hydrographic surveying and processing, and the increased use of marine spatial data.

    Full Text Available In the context of globalization and due to the accelerated progress made in information and communication technology, more and more companies offer their employees the option of telecommuting. For the past twenty years, telecommuting has been on an asceding trend, an incresing number of people embracing the ability to work from home, using a computer and internet connection to communicate for their jobs. The goal of the paper is to explain the overall notion of telecommuting and to analyze the current trends in the United States and European Union markets. Another objective is to assess the advantages and disadvantages of telecommuting and the important role played by this concept within the striving purpose of corporations to achieve their strategic targets. The study is based upon specialized literature reviews regarding the emergence of telecommuting and the role it plays in organizations. A comparative analysis was conducted by the authors on two regional markets, United States and the European Union, in order to assess the trend in telecommuting and the factors that influence it. The outcome of the research shows that although the benefits of telecommuting are numerous, it does not come without challenges, both being applicable for both the employer, as well as for the employee. The research results of this study can be used by organizations when considering to offer their employees flexible work opportunities which can positively influence the long term business performance.

  18. A Review of Trends in Distance Education Scholarship at Research Universities in North America, 1998-2007

    Directory of Open Access Journals (Sweden)

    Randall S. Davies

    2010-10-01

    Full Text Available This article explores and summarizes trends in research and scholarship over the last decade (i.e., 1998-2007 for students completing dissertations and theses in the area of distance education. The topics addressed, research designs utilized, and data collection and analysis methods used were compiled and analyzed. Results from this study indicate that most of the distance education research conducted by graduate students in this period of time has been descriptive, often addressing the perceptions, concerns, and satisfaction levels of various stakeholders with a particular distance education experience. Studies of this type typically used self-report surveys and analyzed the data using descriptive statistics. Validating the concern of many distance education scholars, there was a lack of graduate student research aimed at developing a theory base in distance education. On a positive note, projects directly comparing distance education with traditional face-to-face classrooms to determine the merit of specific programs declined significantly in 2007 as compared to 1998. This result might indicate that distance learning is becoming accepted as a viable and important educational experience in its own right. Another encouraging finding was the decreased emphasis on studies focused on technology issues, such as those analyzing the quality of distance education technology and questioning educators’ ability to provide an acceptable technology-enabled distance learning experience.

    Levy, Rona L; van Tilburg, Miranda A L

    2012-01-01

    The present review summarizes many of the major research trends investigated in the past five years regarding pediatric functional abdominal pain, and also summarizes the primary related findings from the authors' research program. Specific areas discussed based on work within the authors' group include familial illness patterns, genetics, traits, and mechanisms or processes related to abdominal pain. Topics covered from research published in the past five years include prevalence and cost, longitudinal follow-up, overlap with other disorders, etiology and mechanisms behind functional abdominal pain and treatment studies. It is hoped that findings from this work in abdominal pain will be interpreted as a framework for understanding the processes by which other pain phenomena and, more broadly, reactions to any physical state, can be developed and maintained in children. The present article concludes with recommendations for clinical practice and research.

    2016-01-01

    Acupuncture has become popular and widely practiced in many countries around the world. Despite the large amount of acupuncture-related literature that has been published, broader trends in the prevalence and scope of acupuncture research remain underexplored. The current study quantitatively analyzes trends in acupuncture research publications in the past 20 years. A bibliometric approach was used to search PubMed for all acupuncture-related research articles including clinical and animal studies. Inclusion criteria were articles published between 1995 and 2014 with sufficient information for bibliometric analyses. Rates and patterns of acupuncture publication within the 20 year observational period were estimated, and compared with broader publication rates in biomedicine. Identified eligible publications were further analyzed with respect to study type/design, clinical condition addressed, country of origin, and journal impact factor. A total of 13,320 acupuncture-related publications were identified using our search strategy and eligibility criteria. Regression analyses indicated an exponential growth in publications over the past two decades, with a mean annual growth rate of 10.7%. This compares to a mean annual growth rate of 4.5% in biomedicine. A striking trend was an observed increase in the proportion of randomized clinical trials (RCTs), from 7.4% in 1995 to 20.3% in 2014, exceeding the 4.5% proportional growth of RCTs in biomedicine. Over the 20 year period, pain was consistently the most common focus of acupuncture research (37.9% of publications). Other top rankings with respect to medical focus were arthritis, neoplasms/cancer, pregnancy or labor, mood disorders, stroke, nausea/vomiting, sleep, and paralysis/palsy. Acupuncture research was conducted in 60 countries, with the top 3 contributors being China (47.4%), United States (17.5%), and United Kingdom (8.2%). Retrieved articles were published mostly in complementary and alternative medicine (CAM

    Animal experiments have been widely conducted in the life sciences for more than a century, and have long been a subject of ethical and societal controversy due to the deliberate infliction of harm upon sentient animals. However, the harmful use of animals may also negatively impact the mental health of researchers themselves. We sought to evaluate the anxiety level of researchers engaged in animal use to analyse the mental stress from animal testing. The State Anxiety Scale of the State-Trait Anxiety Inventory (STAI) was used to evaluate how researchers feel when they conduct animal, as opposed to non-animal, based experiments (95 non-animal and 98 animal testing researchers). The Trait Anxiety Scale of STAI was employed to measure proneness to anxiety, namely the base trait of the researchers. Additionally, the information on sex, age, education, income, and total working periods was collected. While the Trait Anxiety scores were comparable (41.5 ± 10.9 versus 42.9 ± 10.1, p = 0.3682, t- test), the State Anxiety scores were statistically significantly higher for animal users than non-animal users (45.1 ± 10.7 versus 41.3 ± 9.4, p = 0.011). This trend was consistent for both male and female. Notably, younger animal testers (≤ 30 years of age) with less work experience (≤ 2 years) and lower income level (≤ 27,000 USD) exhibited higher anxiety scores, whereas these factors did not affect the anxiety level of non-animal users. The present study demonstrated that participation in animal experiments can negatively impact the mental health of researchers.

  2. Trends in gluten research and its relationship to autoimmune and allergic diseases

    Directory of Open Access Journals (Sweden)

    Edward J. Ciaccio

    Full Text Available Introduction: Gluten is a protein found in certain grains, and causes an autoimmune response in celiac disease patients. Although the subject of considerable research, gluten research foci and future directions are largely unknown. Methods: The MEDLINE search tool was used to evaluate research trends. For perspective, yearly publications on gluten and other celiac disease reactive proteins were compared to food allergy proteins research. Then the relationship of gluten publications to affiliated keywords was determined. The affiliated keywords belonged to one of several groups: grains, vitamins and minerals, interaction, autoimmunity, genetics, or enzymes. The yearly number of publications in the peer-reviewed medical literature was determined for each relationship from years 1960–2013. The relationships were graphed, and linear regression analysis was used to determine the rate of change in publications per year, and the coefficient of determination. Results: Among celiac disease reactive proteins (gluten, gliadin, and glutenin and selected food allergy proteins (ovalbumin, lysozyme, ovomucoid, and Ara h, gluten showed the greatest rate of increase in published medical research (+20.01 studies/year since 1996, r2=0.97. Additionally, there were sharp increases in the rate of gluten research publications per year in association with keywords ‘autoimmunity’ (+7.69 studies/year since 1997, ‘wheat’ (+6.08 studies/year since 1999, and ‘transglutaminase’ enzyme (+5.05 studies/year since 1995. The longest running moderate trend was research on ‘gluten’ and ‘antibodies’ (+2.50 studies/year, r2=0.92 since 1971. Conclusions: Research on gluten as a reactive protein is of rapidly growing interest in the medical literature. MEDLINE is helpful to determine foci and future directions. Keywords: Celiac disease, Gluten, Gliadin, Medline, Transglutaminase

    There are numerous national efforts to determine and develop research priorities of medical education in Saudi Arabia. These priorities were first proposed in 2010 by "Dr Al-Khuli's Chair for Developing Medical Education in Saudi Arabia". The proposed priority domains were: curriculum, students, faculty, and quality assurance and accreditation. To investigate publications in medical education at the national and international levels in areas relating to these proposed priorities. Electronic search within PubMed database for papers relating to each domain of priority was conducted at national and international levels in the last three years, using the same keywords as the priority domains, but only confined to undergraduate medical education. Out of 3145 articles retrieved when searching with keyword as broad as "undergraduate medical curriculum" only 81 articles worldwide and 3 articles from Saudi Arabia were dealing with curriculum related issues as a whole. Further search on the sub-domains "effective strategies to manage undergraduate curriculum" and "undergraduate medical education models", resulted in the retrieval of few articles worldwide and none from Saudi Arabia. At the national level, there were 63 publications from Saudi Arabia that were either course (topic)-specific or could not be classified under the four domains specified by Dr Al-Khuli's Chair. Research activities in medical education in Saudi Arabia in the last 3 years showed diversity and lack of focus in the research priorities. Efforts of academic and research centers should continue to monitor and encourage these activities toward achieving the recommended priorities.

    Full Text Available Background: The purpose of this study was to investigate social media technology trends in Nielsen – a global information and measurement company – and to establish how these technologies can help the company to create a knowledge-sharing culture.Objective: The objective of this study was to investigate trends in knowledge-sharing technologies in Nielsen.Method: The researchers distributed semi-structured questionnaires to a sample of employees in Nielsen’s Television Audience Measurement Department. They also conducted interviews with specific employees in this department to gain a better understanding of employees’ attitudes toward, and perceptions of, the use of social media tools for creating a knowledgesharing culture at Nielsen. The researchers validated the data to see whether it could support the research and used triangulation to create a holistic view of the data they received from the questionnaires.Results: The findings of the study revealed that respondents had a positive attitude to sharing knowledge with one another through using social media tools. However, some respondents thought that technology, in general, was ‘the tree of good and evil’. The survey findings showed that Nielsen did have social media tools. However, not all employees were aware of these tools or were willing to use the tools to share knowledge. This study highlighted the possible advantages of the social media for sharing knowledge and how Nielsen could use the tools more widely.Conclusion: In order for a knowledge sharing culture to thrive at Nielsen, its employees need to engage more with social media tools in their business practices.

    2009-07-01

    Full Text Available This paper considers current trends in academic research and publication, in particular as seen from the control community. The introduction of Web 2.0 applications for scientists and engineers is currently changing the way research is being conducted. In the near future, participants in the research community will be able to share ideas, data and results like never before. They will also be able to manage the rapidly increasing amount of scientific information much more effectively than today through collaborative efforts enabled by the new Internet tools. However, an important premise for such a development is the availability of research material. Many research results are currently shielded behind expensive subscription schemes that impede the sharing of information. At the same time, an increasing amount of research is being published through open access channels with unrestricted availability. Interestingly, recent studies show that such policies contribute to an increased number of citations compared to the pay-based alternatives. In sum, the parallel development of new tools for research collaboration and an increased access to research material may fundamentally transform the way research is going to be conducted in the future.

    While surveys of technical progress and tasks of EUVL in Japan and overseas are under way for submitting a proposition for the industrialization of EUVL technology by expatiating the results of the EUVL research and development program scheduled to be complete in fiscal 2001, the future of EUVL is considered. The survey results are summarized in five chapters which involve (1) the outlines of survey and research results, (2) technical trends of lithography, (3) systems for EUVL research and development in the world, and (5) the conclusion. In chapter (4), light sources, systems (exposure devices), masks, resists, and other element technologies are investigated. The survey results about light sources involve the background against which their development is described, performance that an extreme ultraviolet ray source is requested to have, candidate EUVL light sources, their technical features and tasks they present, and the latest trends overseas. Concerning the exposure device, the body (device constitution), stage, sensor, projection system, and the irradiation system are investigated. As for masks, the outline of a EUVL mask, masking substrate, multilayer film fabrication, masking pattern formation, and other tasks for development are investigated. (NEDO)

    This year's survey offered examples of evolving partnerships between the public and EMS providers with a growing number of systems implementing PAD programs. The apparent influence of a communication center's managing agency on prioritization strategies is concerning. However, further study is needed. EMS managers must pay careful attention to comm center practices and technology to ensure their ability to support response prioritization and the efficient management of EMS resources. The small reduction in the use of hot response (lights and siren) to every request for service is disappointing in light of medical literature and position statements that condemn this practice. Resource response can be safely prioritized using today's EMD protocol systems. Prioritization and changing response [figure: see text] time requirements to address impending revenue and service demand changes will require additional standardization of methodologies and reporting of response times to relate this measure to other system performance indicators (e.g., patient morbidity/mortality, cost, customer satisfaction, etc.). The future presents a difficult road for system administrators. However, the adoption of a growing number of information-management tools and changes in procedures and dispatch processes offer potential solutions. The increased use of hand-held computers or personal digital assistant (PDAs) to gather and provide information and the almost universal use of CAD will aid providers in performing the research necessary to change response time performance requirements, improving EMS system efficiency. Use of this technology will also likely improve patient care and reimbursement through more timely and accurate reporting and analysis. The medical director's role will be critical to ensuring potential changes don't compromise patient care. Obtaining a better understanding of how much time can safely elapse between the time of the 9-1-1 call and when patient-care activities

    Health research is one mechanism to improve population-level health and should generally match the health needs of populations. However, there have been limited data to assess the trends in national-level cardiovascular research output, even as cardiovascular disease [CVD] has become the leading cause of morbidity and mortality worldwide. We performed a time trends analysis of cardiovascular research publications (1999-2008) downloaded from Web of Knowledge using a iteratively-tested cardiovascular bibliometric filter with >90% precision and recall. We evaluated cardiovascular research publications, five-year running actual citation indices [ACIs], and degree of international collaboration measured through the ratio of the fractional count of addresses from one country against all addresses for each publication. Global cardiovascular publication volume increased from 40 661 publications in 1999 to 55 284 publications in 2008, which represents a 36% increase. The proportion of cardiovascular publications from high-income, Organization for Economic Cooperation and Development [OECD] countries declined from 93% to 84% of the total share over the study period. High-income, OECD countries generally had higher fractional counts, which suggest less international collaboration, than lower income countries from 1999-2008. There was an inverse relationship between cardiovascular publications and age-standardized CVD morbidity and mortality rates, but a direct, curvilinear relationship between cardiovascular publications and Human Development Index from 1999-2008. Cardiovascular health research output has increased substantially in the past decade, with a greater share of citations being published from low- and middle-income countries. However, low- and middle-income countries with the higher burdens of cardiovascular disease continue to have lower research output than high-income countries, and thus require targeted research investments to improve cardiovascular health.

  11. Gender Authorship Trends of Plastic Surgery Research in the United States.

    An increasing number of women are entering the medical profession, but plastic surgery remains a male-dominated profession, especially within academia. As academic aspirations and advancement depend largely on research productivity, the authors assessed the number of articles authored by women published in the journal Plastic and Reconstructive Surgery. Original articles in Plastic and Reconstructive Surgery published during the years 1970, 1980, 1990, 2000, 2004, and 2014 were analyzed. First and senior authors with an M.D. degree and U.S. institutional affiliation were categorized by gender. Authorship trends were compared with those from other specialties. Findings were placed in the context of gender trends among plastic surgery residents in the United States. The percentage of female authors in Plastic and Reconstructive Surgery increased from 2.4 percent in 1970 to 13.3 percent in 2014. Over the same time period, the percentage of female plastic surgery residents increased from 2.6 percent to 32.5 percent. By 2014, there were more female first authors (19.1 percent) than senior authors (7.7 percent) (p < 0.001). As a field, plastic surgery had fewer female authors than other medical specialties including pediatrics, obstetrics and gynecology, general surgery, internal medicine, and radiation oncology (p < 0.05). The increase in representation of female authors in plastic surgery is encouraging but lags behind advances in other specialties. Understanding reasons for these trends may help improve gender equity in academic plastic surgery.

  12. Recent trends in the U.S. Behavioral and Social Sciences Research (BSSR workforce.

    Directory of Open Access Journals (Sweden)

    Hyungjo Hur

    Full Text Available While behavioral and social sciences occupations comprise one of the largest portions of the "STEM" workforce, most studies of diversity in STEM overlook this population, focusing instead on fields such as biomedical or physical sciences. This study evaluates major demographic trends and productivity in the behavioral and social sciences research (BSSR workforce in the United States during the past decade. Our analysis shows that the demographic trends for different BSSR fields vary. In terms of gender balance, there is no single trend across all BSSR fields; rather, the problems are field-specific, and disciplines such as economics and political science continue to have more men than women. We also show that all BSSR fields suffer from a lack of racial and ethnic diversity. The BSSR workforce is, in fact, less representative of racial and ethnic minorities than are biomedical sciences or engineering. Moreover, in many BSSR subfields, minorities are less likely to receive funding. We point to various funding distribution patterns across different demographic groups of BSSR scientists, and discuss several policy implications.

    Objective: The objective of this study was to investigate trends in knowledge-sharing technologies in Nielsen. Method: The researchers distributed semi-structured questionnaires to a sample of employees in Nielsen’s Television Audience Measurement Department. They also conducted interviews with specific employees in this department to gain a better understanding of employees’ attitudes toward, and perceptions of, the use of social media tools for creating a knowledgesharing culture at Nielsen. The researchers validated the data to see whether it could support the research and used triangulation to create a holistic view of the data they received from the questionnaires. Results: The findings of the study revealed that respondents had a positive attitude to sharing knowledge with one another through using social media tools. However, some respondents thought that technology, in general, was ‘the tree of good and evil’. The survey findings showed that Nielsen did have social media tools. However, not all employees were aware of these tools or were willing to use the tools to share knowledge. This study highlighted the possible advantages of the social media for sharing knowledge and how Nielsen could use the tools more widely. Conclusion: In order for a knowledge sharing culture to thrive at Nielsen, its employees need to engage more with social media tools in their business practices.

    Inquiry-driven learning, research internships and course-based undergraduate research experiences all represent mechanisms through which educators can engage undergraduate students in scientific research. In life sciences education, the benefits of undergraduate research have been thoroughly evaluated, but limitations in infrastructure and training can prevent widespread uptake of these practices. It is not clear how faculty members can integrate complex laboratory techniques and equipment into their unique context, while finding the time and resources to implement undergraduate research according to best practice guidelines. This review will go through the trends and patterns in inquiry-based undergraduate life science projects with particular emphasis on molecular biosciences-the research-aligned disciplines of biochemistry, molecular cell biology, microbiology, and genomics and bioinformatics. This will provide instructors with an overview of the model organisms, laboratory techniques and research questions that are adaptable for semester-long projects, and serve as starting guidelines for course-based undergraduate research. © FEMS 2017.

    The aim of this study was to analyze trends and factors associated with food insecurity in Brazil in 2004, 2009, and 2013, using microdata from the National Household Sample Survey (PNAD). Food insecurity was assessed using the Brazilian Food Insecurity Scale. Independent variables were selected from a conceptual model of determination of food insecurity, which was also used in the elaboration of multiple generalized linear models. The results show a downward trend in food insecurity prevalence from 2004 to 2013, especially for moderate and severe food insecurity, from 17% in 2004 (95%CI: 15.7-18.4) to 7.9% in 2013 (95%CI: 7.2-8.7). Despite important decreases in the prevalence of moderate and severe food insecurity, regardless of the level of determination, the population strata with the lowest prevalence in 2004 showed the largest relative reduction. As for factors associated with moderate and severe food insecurity, they remained the same in the ten years covered by the PNAD survey, namely: the North and Northeast regions, urban areas with inadequate sanitation, household density > 2 persons per bedroom, ≤ 4 household durable consumer goods, and households headed by females, individuals insecurity dropped by half, but from the perspective of equity the advances occurred unequally and were lower in strata with greater social, economic, and demographic vulnerability.

    Research trends in CO chemistry in the U.S. include the development of stable and selective homogeneous catalysts which would facilitate the removal of the heat of reaction and be resistant to sulfur poisoning for the methanation reaction, methanol synthesis, and Fischer-Tropsch synthesis; development of low-temperature homogeneous water gas shift catalysts; and research on the coordination chemistry and photochemical conversions of CO/sub 2/. In 1977, the National Science Foundation awarded 16 contracts for a total of $720,000 to promote the research in this field, including studies on chemisorption and heterogeneous catalysis (four contracts) and on transition metal complexes (ten contracts, of which seven are dedicated to metal clusters). Carbon monoxide-based processes, including water gas shift reactions, CO reduction to alkanes and alcohols, hydroformylation, and homogeneous carbonylation processes, recently developed in the U.S. are listed.

  17. Current nondestructive evaluation research and development trends in the United States

    1992-01-01

    An underlying theme present in much of the nondestructive evaluation (NDE) research and development occurring in the United States as well as worldwide is the application of physics and engineering principles toward understanding and optimizing NDE processes. Expanding this trend of using mathematical models for NDE processes is critical to the entire spectrum of NDE technology. In NDE research, modeling anchors the investigation in scientific, proven principles and establishes a firm technical basis to guide the design and development of inspection equipment and approaches. It also provides for understanding the capabilities and the limitations of whatever designs are selected and ultimately applied in the field. This paper reviews the status of these efforts, presents several examples where mathematical modeling is being profitably used for practical inspection work, and shows the path being taken in ongoing research.

    Full Text Available The editor suggested us to write about our point of view on the current use of Operations Research techniques applied to the Operations Management and about its future evolution. With some of unconsciousness we accept it, but it is obvious that our vision, even though we try to do our best, will be partial and biased. Hence the title chosen shows signs of prudence. More caution have been applied to the development where, after a glance at the past and reflection on the abundance of new denominations without content, we consider five aspects that, nowadays, acquire increasing importance and that will strongly influence in future developments. Among the five aspects two correspond to trends in the field of operations research techniques, one is a philosophy in the field of operations management, another to an area of the company and the last one to an industrial sector in which operations management, supported by operations research methods, is taking a predominant role.

    The continuity for discovery and production of new chemicals, allied products, and uses has currently resulted into generation of recent form of contaminants known as Emerging Contaminants (ECs). Once in the aquatic environment ECs are carcinogenic and cause other threats to both human's and animals' health. Due to their effects this study was aimed at investigating research trends of ECs in Tanzania. Findings revealed that USA and EU countries were leading in ECs researches, little followed by Asia, South Africa, and then Zambia. Only few guidelines from USA-EPA, WHO, Canada, and Australia existed. Neither published guidelines nor regulations for ECs existed in Tanzania; rather only the occurrence of some disinfection by-products and antibiotics was, respectively, reported in Arusha and Dar es Salaam, Tanzania. As these reports had a limited coverage of ECs, henceforth, these findings constitute the first-line reference materials for ECs research in Tanzania which shall be useful for future monitoring and regulation planning.

    Vector-borne pathogens impact public health, animal production, and animal welfare. Research on arthropod vectors such as mosquitoes, ticks, sandflies, and midges which transmit pathogens to humans and economically important animals is crucial for development of new control measures that target transmission by the vector. While insecticides are an important part of this arsenal, appearance of resistance mechanisms is increasingly common. Novel tools for genetic manipulation of vectors, use of Wolbachia endosymbiotic bacteria, and other biological control mechanisms to prevent pathogen transmission have led to promising new intervention strategies, adding to strong interest in vector biology and genetics as well as vector–pathogen interactions. Vector research is therefore at a crucial juncture, and strategic decisions on future research directions and research infrastructure investment should be informed by the research community. A survey initiated by the European Horizon 2020 INFRAVEC-2 consortium set out to canvass priorities in the vector biology research community and to determine key activities that are needed for researchers to efficiently study vectors, vector-pathogen interactions, as well as access the structures and services that allow such activities to be carried out. We summarize the most important findings of the survey which in particular reflect the priorities of researchers in European countries, and which will be of use to stakeholders that include researchers, government, and research organizations.

  2. The trend of the research and development for the upgrade of the high current energy system

    International Nuclear Information System (INIS)

    2010-01-01

    The high current energy technology ranges from a basic technology of the electric power field to a state-of-the-art technology and has been used extremely variously. In addition, as the energy technology advances, the expansion of applied field, such as the nuclear fusion and the exhaust thing processing, etc., requires a further upgrade of the large current technology. In this report, the trend of the research and development for the upgrade of the high current energy technology are summarized. In the following, the elemental technology including arc/plasma phenomena and the pulse power system is described in Chapter 2. In Chapter 3, the trend of the research and development for the upgrade of various equipments and devices such as the nuclear fusion development, the superconducting applications of SMES and the maglev transportation system, and the arc application of the exhaust processing for a medical waste, the radio active waste and a detrimental gas and the next generation lithography system. In Chapter 4, the analysis and the measurement technology of the arc phenomenon and the standardization of current shunt, etc are described. We hope this research report can contribute to the promotion of technical exchanges in different fields, and offer guidelines for future development in this high current energy technology. (author)

    2008-09-01

    The authors conducted a content analysis of all articles published in the Journal of Applied Psychology and Personnel Psychology from January 1963 to May 2007 (N = 5,780) to identify the relative attention devoted to each of 15 broad topical areas and 50 more specific subareas in the field of industrial and organizational (I-O) psychology. Results revealed that (a) some areas have become more (or less) popular over time, whereas others have not changed much, and (b) there are some lagged relationships between important societal issues that involve people and work settings (i.e., human-capital trends) and I-O psychology research that addresses them. Also, much I-O psychology research does not address human-capital trends. Extrapolating results from the past 45 years to the next decade suggests that the field of I-O psychology is not likely to become more visible or more relevant to society at large or to achieve the lofty goals it has set for itself unless researchers, practitioners, universities, and professional organizations implement significant changes. In the aggregate, the changes address the broad challenge of how to narrow the academic-practitioner divide.

    Fiber-to-the-Premise (FTTP), a keyword in the current fiber and cable industry, leads us variegated directions of the research and development activities. In fact, this momentum of industry seems to be weak yet, since the bandwidth demand by market is still unbalanced to the capacity in the several market segments. However, the recent gradual recovery in metro and access network indicates a positive sign for FTTP deployment projects. It is the very preferable for us to optimize R&D strategy applicable to the current market trend of sequential investment.

    2018-01-01

    This study visualized and analyzed the developing trends and hot topics in natural disaster research. 19694 natural disaster-related articles (January 1900 to June 2015) are indexed in the Web of Science database. The first step in this study is using complex networks to visualize and analyze these articles. CiteSpace and Gephi were employed to generate a countries collaboration network and a disciplines collaboration network, and then attached hot topics to countries and disciplines, respectively. The results show that USA, China, and Italy are the three major contributors to natural disaster research. "Prediction model", "social vulnerability", and "landslide inventory map" are three hot topics in recent years. They have attracted attention not only from large countries like China but also from small countries like Panama and Turkey. Comparing two hybrid networks provides details of natural disaster research. Scientists from USA and China use image data to research earthquakes. Indonesia and Germany collaboratively study tsunamis in the Indian Ocean. However, Indonesian studies focus on modeling and simulations, while German research focuses on early warning technology. This study also introduces an activity index (AI) and an attractive index (AAI) to generate time evolution trajectories of some major countries from 2000 to 2013 and evaluate their trends and performance. Four patterns of evolution are visible during this 14-year period. China and India show steadily rising contributions and impacts, USA and England show relatively decreasing research efforts and impacts, Japan and Australia show fluctuating activities and stable attraction, and Spain and Germany show fluctuating activities and increasing impacts.

    Recent eHealth developments have elevated the importance of assessing the extent to which technology has empowered patients and improved health, particularly among the most vulnerable populations. With noted disparities across racial and social groups in chronic health outcomes, such as cancer, obesity, and diabetes, it is essential that researchers examine any differences in the implementation, uptake, and impact of eHealth strategies across groups that bear a disproportionate burden of disease. The goal was to examine eHealth use by sociodemographic factors, such as race/ethnicity, socioeconomic status (SES), age, and sex. We drew data from National Cancer Institute's 2012 Health Information National Trends Survey (HINTS) (N=3959) which is publicly available online. We estimated multivariable logistic regression models to assess sociodemographic predictors of eHealth use among adult Internet users (N=2358) across 3 health communication domains (health care, health information-seeking, and user-generated content/sharing). Among online adults, we saw no evidence of a digital use divide by race/ethnicity. However, there were significant differences in use by SES, particularly for health care and health information-seeking items. Patients with lower levels of education had significantly lower odds of going online to look for a health care provider (high school or less: OR 0.50, 95% CI 0.33-0.76) using email or the Internet to communicate with a doctor (high school or less: OR 0.46, 95% CI 0.29-0.72), tracking their personal health information online (high school or less: OR 0.53, 95% CI 0.32-0.84), using a website to help track diet, weight, and physical activity (high school or less: OR 0.64, 95% CI 0.42-0.98; some college: OR 0.67, 95% CI 0.49-0.93), or downloading health information to a mobile device (some college: OR 0.54, 95% CI 0.33-0.89). Being female was a consistent predictor of eHealth use across health care and user-generated content/sharing domains

    Background: The details about the research productivity in the specialty of endocrinology from India is lacking. We plan to assess the publishing trends and the research productivity of Endocrinology related research articles published in the Journal of the Association of Physicians of India (JAPI). Materials and Methods: We carried the bibliometric analysis of endocrinology related articles from JAPI. The data were obtained from the JAPI website for the publications between 2000 and 2011. The articles were analyzed for the type (original article, case reports, correspondence, and pictorial image), subspecialty (diabetes, thyroid, etc.), and place of the research. Data were presented with descriptive statistics in numbers and percentages. Results: Out of a total 2977 articles published by JAPI, 312 articles belong to endocrine subspecialty. Endocrinology related articles constitute about 11.2%–23.2% of the published articles per year in JAPI and the percentage is increasing every year. Original articles (52%) and case reports (27%) constituite the majority, while the rest were letters to editor (9%) and pictorial images (12%). Diabetes (57%) and metabolic bone disorders (16%) lead the subspecialty articles, followed by thyroid (9%), adrenal and gonad (8%), and pituitary (8%). Chennai (20%), Mumbai (14%), and Delhi (9%) are the top 3 places contributing to the articles followed by Chandigarh and Varanasi. Conclusion: Majority of endocrinology related research productivity is seen in form of original articles and case reports. Diabetes is the leading disease with maximum research articles from Chennai and other glands are equally represented in the research productivity. PMID:23226637

    China, as a rapidly developing country with the largest population in the world, is playing an increasingly important role in diabetes research. There are >10,000 diabetes doctors who care for a large population of diabetic patients. The quantity and quality of research on diabetes from 3 major regions of China, including Mainland China (ML), Taiwan (TW), and Hong Kong (HK), is unknown. We aimed to analyze the contributions of each of these 3 regions to diabetes research.Articles on diabetes originating from ML, TW, and HK that were published from 2005 to 2014 were retrieved from the Web of Science. The quantity of articles, citations, article types, and articles published in high-impact journals were analyzed.A total of 9302 articles were retrieved from the 3 regions of China. There were 6775 from ML, 1993 from TW, and 534 from HK, with an increasing trend in publications from 2005 to 2014. After 2006, the number of publications from ML exceeded TW and HK. The largest total number of citations (48,296) was from ML. The highest mean citations, however, were from HK (15.90). PLoS One was the most popular journal in all 3 regions. The greatest number of RCTs, clinical trials, meta-analyses, and articles published in high-impact journals were from ML.There has been a significant increase in the number of articles published on diabetes research from China during the past 10 years. Most of the articles were published by authors in ML, and an increasing trend began in 2006. HK had the highest quality research output in terms of mean citations per article.

    The survey method is often used to identify trends in sexual behaviour and attitudes. In order for research conclusions to be valid, however, data gathered from surveys must be unambiguous. For the current paper we reviewed survey research of sexual behaviour published in recent years. Our objective was to identify common methodological issues and provide recommendations for how to address them. We examined 62 articles, published in four prominent sexual health journals over the past six years. We evaluated each article based on how adequately its authors addressed four recurring methodological issues: ambiguous terminology, heterosexual bias, procedures that compromise honesty in responses, and survey language/literacy considerations. The review revealed some recurring issues: 47% of the studies failed to address the question of sexual orientation, sexual behaviour terminology was explicitly defined in only 32% of questionnaires, fewer than 5% of surveys clarified whether the sexual encounters in question were consensual, and 21% of the articles contained no mention of anonymity or confidentiality for participants. These results reveal common issues with survey data that compromise the validity of findings. In order to have confidence in research conclusions and recommendations, it is important that these issues be addressed.
