    Brassell, S. C.

    2014-12-01

    "Records of Global Climate Change" enables students to fulfill the science component of an undergraduate distribution requirement in "Critical Approaches" at IU Bloomington. The course draws students from all disciplines with varying levels of understanding of scientific approaches and often limited familiarity with climate issues. Its discussion sessions seek to foster scientific literacy via an alternating series of assignments focused on a combination of exercises that involve either examination and interpretation of on-line climate data or consideration and assessment of the scientific basis of new discoveries about climate change contained in recently published media articles. The final assignment linked to the discussion sessions requires students to review and summarize the topics discussed during the semester. Their answers provide direct evidence of newly acquired abilities to assimilate and evaluate scientific information on a range of topics related to climate change. In addition, student responses to an end-of-semester survey confirm that the vast majority considers that their knowledge and understanding of climate change was enhanced, and unsolicited comments note that the discussion sessions contributed greatly to this advancement. Many students remarked that the course's emphasis on examination of paleoclimate records helped their comprehension of the unprecedented nature of present-day climate trends. Others reported that their views on the significance of climate change had been transformed, and some commented that they now felt well equipped to engage in discussions about climate change because they were better informed about its scientific basis and facts.

    As neuroscience research advances, researchers, clinicians, and other stakeholders will face a host of ethical challenges. The Presidential Commission for the Study of Bioethical Issues (Bioethics Commission) has published two reports that provide recommendations on how to advance research endeavors ethically. The commission addressed, among other issues, how to prioritize different types of neuroscience research and how to include research participants who have impaired consent capacity. The Bioethics Commission's recommendations provide a foundation for ethical guidelines as neuroscience research advances and progresses.

  10. Advances in complex electromagnetic media

    Science.gov (United States)

    Kundtz, Nathan

    In this dissertation the tools used in the field of transformation optics will be explored and expanded. Several new designs are discussed, each of which expands upon the ideas that have previously been employed in the field. To begin, I show that the explicit use of a transformation which extends throughout all space may be used to reduce the overall size of an optical device without changing its optical properties. A lens is chosen as a canonical device to demonstrate this behavior. For this work I provided the original idea for a compressing transformation as well as its dielectric-only implementation. For a particular functionality the choice of transformation is, in general, not unique. It is natural, then, to seek optimized transformations which reduce the complexity of the final structure. It was recently demonstrated that for some transformations a numerical scheme could be employed to find quasi-conformal transformations for which the requisite complex material distribution could be well approximated by an isotropic, inhomogeneous media. This process was previously used to demonstrate a carpet cloak---a device which masks a bump in a mirror surface. Unlike the more common transformation optical media, which exhibit strong losses at high frequencies, isotropic designs can be readily made to function at infrared or even optical frequencies. The prospect of leveraging transformation optics in devices which operate at high frequencies, into the infrared and visible, motivates the use of quasi-conformal transformations in lens design. I demonstrate how transformation optics can be used to take a classical lens design based on spherical symmetry, such as a Luneburg lens, and warp it to suit the requirements of a planar imaging array. I report on the experimental demonstration of this lens at microwave frequencies. In the final design a lens is demonstrated in a two-dimensional field mapping waveguide to have a field of view of ˜ 140° and a bandwidth exceeding

    Valkenburg, Patti M; Peter, Jochen; Walther, Joseph B

    2016-01-01

    This review analyzes trends and commonalities among prominent theories of media effects. On the basis of exemplary meta-analyses of media effects and bibliometric studies of well-cited theories, we identify and discuss five features of media effects theories as well as their empirical support. Each of these features specifies the conditions under which media may produce effects on certain types of individuals. Our review ends with a discussion of media effects in newer media environments. This includes theories of computer-mediated communication, the development of which appears to share a similar pattern of reformulation from unidirectional, receiver-oriented views, to theories that recognize the transactional nature of communication. We conclude by outlining challenges and promising avenues for future research.

  16. Service interoperability through advanced media gateways

    CERN Document Server

    van der Meer, S

    2000-01-01

    The convergence of telecommunications systems and the Internet causes a variety of concepts for service integration. The focus of the recent research studies and the work of several standardization bodies lies mostly on the interworking of services and the universal service access from end-user systems including both fixed and wireless terminals. All approaches are driven by the concept of providing several technologies to users by keeping the peculiarity of each service alive. But, developments should not only concentrate on media adaptation between VoIP and PSTN, but also consider the adaptation among completely different types of applications as for example E- mail, facsimile, or voice. Unified messaging, which is an already accepted service on the market, provides solutions for conversions of different application protocols into each other. The functionality of converting one medium into another is implemented here in so-called media gateways. This paper provides an overview of the current developments in...

  17. Researching media through practices: an ethnographic approach

    Directory of Open Access Journals (Sweden)

    Antoni Roig

    2009-05-01

    Full Text Available Anthropological and ethnographic research on media have been largely focused on analyzing reception of media products (television, radio, press and film and media consumption related to domestic appropriation of technologies (Rothenbuhler et al., 2005. There is also a wide body of research devoted to the study of the political dimension of alternative and indigenous media (Ginsburg, 2002. However, there has been a separation between media and internet studies, and between the analysis of media reception and practices of self-production, such as family photography or home video. Current digital media practices urge reexamination of self-produced content and media flows from a broader perspective that cuts across divisions between public and private, corporative media products and people's releases, home production and cultural industry, political activism and everyday life.

    Tree-ring studies in China have achieved great advances since the 1990s, particularly for the dendroclimatological studies which have made some influence around the world. However, because of the uneven development, limited attention has been currently paid on the other branches of dendrochronology. We herein briefly compared the advances of dendrochronology in China and of the world and presented suggestions on future dendrochronological studies. Large-scale tree-ring based climate reconstructions in China are highly needed by employing mathematical methods and a high quality tree-ring network of the ring-width, density, stable isotope and wood anatomy. Tree-ring based field climate reconstructions provide potentials on explorations of climate forcings during the reconstructed periods via climate diagnosis and process simulation.

    Fostering translational research of advanced therapies has become a major priority of both scientific community and national governments. Advanced therapy medicinal products (ATMP) are a new medicinal product category comprising gene therapy and cell-based medicinal products as well as tissue engineered medicinal products. ATMP development opens novel avenues for therapeutic approaches in numerous diseases, including cancer and neurodegenerative and cardiovascular diseases. However, there are important bottlenecks for their development due to the complexity of the regulatory framework, the high costs and the needs for good manufacturing practice (GMP) facilities and new end-points for clinical experimentation. Thus, a strategic cooperation between different stakeholders (academia, industry and experts in regulatory issues) is strongly needed. Recently, a great importance has been given to research infrastructures dedicated to foster translational medicine of advanced therapies. Some ongoing European initiatives in this field are presented and their potential impact is discussed.

  19. Advances in stem cell research

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    @@In 1998, biologists Thomson and Gearhart successfully derived stem cells from human embryos. One year later, several researchers discovered that adult stem cells still retain the ability to be differentiated into unrelated types of cells. Advances in stem cell research open a promising direction for applied medical science. Moreover, it may also force scientists to reconsider the fundamental theory about how cells grow up. Stem cell research was considered by Science as the top of the ten breakthroughs of science of the year[1]. This paper gives a survey of recent advances in stem cell research. 1 Overview In the 1980s, embryonic stem cell and/or embryonic germ cell line (ES cell line, EG cell line) of multifarious mammalian animals, especially those of non-human pri-mates, had been established. In 1998, Thomson and Shamblott obtained ES, EG cell lines from human blasto-cysts and gonad ridges of early human embryos, respec-tively. Their research brought up an ethical debate about whether human embryos can be used as experimental materials. It was not appeased until 1999 when research-ers discovered that stem cells from adults still retain the ability to become different kinds of tissue cells. For in-stance, brain cells can become blood cells[2], and cells from bone marrow can become cells in liver. Scientists believe, for a long time, that cells can only be developed from early pluripotent embryo cells; the differentiation potential of stem cells from mature tissues is restricted to only one of the cell types of the tissue where stem cells are obtained. Recent stem cell researches, however, sub-verted the traditional view of stem cells. These discoveries made scientists speed ahead with the work on adult stem cells, hoping to discover whether their promise will rival that of ES cells.

    2001-01-01

    The tectonic movement at human scale has not been fully understood yet, especially for active tectonics, although it is the basis to study natural hazards and environmental variations. Many national and international scientific plans related closely to active tectonics research have been made in the past ten years. This paper briefly summarized the background of the undertaking of active tectonics research, its advances and existing problems, and the key points in its future studies are also pointed out. The emerging of new technologies like the Earth Observing Sys tem, Digital Seismology and so on provides unusual opportunities for tectonic research. It is emphasized, however, that careful analyses and building up of new theoretical frame are sill the key problems for studies of active tectonics, especially for active tectonics in China' s conti nent.

    2013-10-01

    Nanoscience has arrived. Biological applications of nanoscience are particularly prominent and can be useful in a range of disciplines. Advances in nanoscience are underpinning breakthroughs in biomedical research and are beginning to be adopted by the rheumatology and musculoskeletal science communities. Within these fields, nanoscience can be applied to imaging, drug delivery, implant development, regenerative medicine, and the characterization of nanoscale features of cells, matrices and biomaterials. Nanoscience and nanotechnology also provide means by which the interaction of cells with their environment can be studied, thereby increasing the understanding of disease and regenerative processes. Although its potential is clear, nanoscience research tends to be highly technical, generally targeting an audience of physicists, chemists, materials scientists and engineers, and is difficult for a general audience to follow. This Review aims to step back from the most technical aspects of nanoscience and provide a widely accessible view of how it can be applied to advance the field of rheumatology, with an emphasis on technologies that can have an immediate impact on rheumatology and musculoskeletal research.

    2014-09-01

    This review of the literature on disaster media coverage describes the events, samples, and forms of media coverage (television, newspapers, radio, internet) studied and examines the association between media consumption and psychological outcomes. A total of 36 studies representing both man-made and natural events met criteria for review in this analysis. Most studies examined disaster television viewing in the context of terrorism and explored a range of outcomes including posttraumatic stress disorder (PTSD) caseness and posttraumatic stress (PTS), depression, anxiety, stress reactions, and substance use. There is good evidence establishing a relationship between disaster television viewing and various psychological outcomes, especially PTSD caseness and PTS, but studies are too few to draw definitive conclusions about the other forms of media coverage that have been examined. As media technology continues to advance, future research is needed to investigate these additional media forms especially newer forms such as social media.

    The need for education does not end with residency. Practicing surgeons must find ways to stay current. The boom in new technologic developments may significantly enhance our methods of teaching through the use of new mutli-media. Here we will explore some of the muti-media innovations that have or may have the greatest impact on surgical education. Live, interactive, and online forums have proven to be effective new methods of bringing people together to discuss and learn new concepts in medicine. These forums allow physicians to interact with key opinion leaders and flatten knowledge sharing, so that everyone may have a voice. The dynamic, fast paced, and interactive format allows for screen-based learning to be engaging and interactive. Information is now available online in multiple formats that are continuously updated, so that information is no longer outdated by the time it is published in a textbook. Multi-media is now being used to disseminate content through, archived video, live video, as well as audiocasts. All of these are creating more modern ways for physicians to stay up-to-date either at home, in the office, or when mobile. Lastly, new advanced, interactive, technology can allow experts to assist less-experienced surgeons as "virtual partners" through telementoring. With telementoring, an expert can be virtually present while another surgeon is performing a complex, new, operation, and the expert can help with voice suggestions and on-screen telestration. Pediatric surgical education has made a giant leap thanks to new developments in multi-media technology.

  12. Mind the gap: social media engagement by public health researchers.

    2014-01-14

    The traditional vertical system of sharing information from sources of scientific authority passed down to the public through local health authorities and clinicians risks being made obsolete by emerging technologies that facilitate rapid horizontal information sharing. The rise of Public Health 2.0 requires professional acknowledgment that a new and substantive forum of public discourse about public health exists on social media, such as forums, blogs, Facebook, and Twitter. Some public health professionals have used social media in innovative ways: to surveil populations, gauge public opinion, disseminate health information, and promote mutually beneficial interactions between public health professionals and the lay public. Although innovation is on the rise, most in the public health establishment remain skeptical of this rapidly evolving landscape or are unclear about how it could be used. We sought to evaluate the extent to which public health professionals are engaged in these spaces. We conducted a survey of professorial- and scientist-track faculty at the Johns Hopkins Bloomberg School of Public Health in Baltimore, Maryland, USA. We asked all available faculty via email to complete a 30-question survey about respondent characteristics, beliefs about social media, and usage of specific technologies, including blogs, Facebook, Twitter, and YouTube. A total of 181 (19.8%) of 912 professor- and scientist-track faculty provided usable responses. The majority of respondents rarely used major social media platforms. Of these 181 respondents, 97 (53.6%) had used YouTube, 84 (46.4%) had used Facebook, 55 (30.4%) had read blogs, and 12 (6.6%) had used Twitter in the prior month. More recent degree completion was the best predictor of higher usage of social media. In all, 122 (67.4%) agreed that social media is important for disseminating information, whereas only 55 (30.4%) agreed that social media is useful for their research. In all, 43 (23.8%) said social media

    分泌性中耳炎是儿童的常见病与多发病,是引起儿童听力下降的常见原因之一。为深入了解儿童分泌性中耳炎与变应性鼻炎之间的内在联系,本文收集了相关研究文献。研究表明分泌性中耳炎与变应性鼻炎之间存在流行病学、病理生理学方面的联系,抗过敏治疗对分泌性中耳炎具有短期疗效并可有效防止分泌性中耳炎复发。采用鼻内类固醇激素治疗后,其治愈率明显增加。这些发现为人们深入研究变态反应性疾病与分泌性中耳炎形成机制间的联系、抗过敏治疗对复发性分泌性中耳炎的有效性以及针对该病更广泛的药物治疗研究提供了重要参考。%Otitis media with effusion is a common and frequently occurring disease in children, and one of the most common causes of hearing loss in the pediatric population. To further understand the relationship between otitis media with effusion and allergic rhinitis in children, relevant research literature was reviewed. Research shows that, from epidemiology and pathophysiology evidence, otitis media with effusion and allergic rhinitis are related, and treatments against allergy are beneficial for otitis media with effusion in short-term and can effectively prevent its recurrence. The rate of recovery from otitis media with effusion is significantly increased after treatment with steroids. These findings provide an important refer-ence for further studies of the relationship between allergic diseases and the mechanisms of pathogenesis of otitis media with effusion, the effectiveness of anti-allergy treatments for recurrent otitis media with effusion, and development of addi-tional medical treatments for the disease.

    2014-12-01

    Full Text Available Social media, generated by advances in internet technology, are heavily used by individuals of every age and every class both in Turkey and all over the world. Social networking sites such as Facebook, Twitter and Google+ make virtual societies possible, and enable ideas, opinions and comments to be shared. This sh aring of visual and auditory context without any limitations has produced a more democratic platform. The democratic structure specific to social media enables them to be used for social and political purposes. In this study, a research is conducted on soc ial/political use of social media in Turkey. Results of the research revealed that majority of the participants (46.6% spend 2 to 4 hours on social media and 75.6% of the participants use smart phones for social media access. 11.2% of participants stated that they use social media for political and social purposes. 78.9% of the participants use Twitter and Facebook for political/social information sharing. 67.7% of participants frequently use Twitter for political/social purposes. In terms of political iss ues, participants prefer to use social media for domestic affairs rather than international affairs. The most controversial result was about the participants’ pessimistic attitude towards social media. Some part of the participants think that social media will not change anything in Turkey, and the other part states that social media usage will divide up the society. Detailed analyses are given throughout the article.

  19. Transculturality as a Perspective: Researching Media Cultures Comparatively

    Directory of Open Access Journals (Sweden)

    Andreas Hepp

    2009-01-01

    Full Text Available Most of the research on media cultures operates in a "national-territorial" frame. Media cultures are considered as national cultures and other forms of media culture (for example professional journalism cultures, diasporas, celebrity cultures etc. are not investigated in their "deterritorial" character. But it is exactly such deterritorial forms of media culture that are gaining relevance with the ongoing pace of media globalization: they therefore have to be placed in the focus of comparative media and communication research. Starting with this consideration, the article develops a transcultural perspective on researching media cultures. Within this perspective it becomes possible to conduct comparative research on (territorial national media cultures as well as on other (deterritorial forms of present media cultures, as this approach moves the processes of cultural construction and articulation into the focus of analysis. To arrive at a better understanding of this approach, "media cultures" are defined as translocal phenomena in their territorial as well as their deterritorial relations. Based on this, the "semantics" of a transcultural research perspective are outlined, which then makes it possible to formulate practical principles for carrying out comparative qualitative research within this framework.

The increase of production yield of LEU metal, the establishment of measurement method of homogeneity, and electron beam welding process were performed. Irradiation test under normal operation condition, had been carried out and any clues of the fuel assembly breakdown was not detected. The 2nd test fuel assembly has been irradiated at HANARO reactor since 17th June 1999. The quality assurance system has been re-established and the eddy current test technique has been developed. The irradiation test for U{sub 3}Si{sub 2} dispersed fuels at HANARO reactor has been carried out in order to compare the in-pile performance of between the two types of U{sub 3}Si{sub 2} fuels, prepared by both the atomization and comminution processes. KAERI has also conducted all safety-related works such as the design and the fabrication of irradiation rig, the analysis of irradiation behavior, thermal hydraulic characteristics, stress analysis for irradiation rig, and thermal analysis fuel plate, for the mini-plate prepared by international research cooperation being irradiated safely at HANARO. Pressure drop test, vibration test and endurance test were performed. The characterization on powders of U-(5.4 {approx} 10 wt%) Mo alloy depending on Mo content prepared by rotating disk centrifugal atomization process was carried out in order to investigate the phase stability of the atomized U-Mo alloy system. The {gamma}-U phase stability and the thermal compatibility of atomized U-16at.%Mo and U-14at.%Mo-2at.%X(: Ru, Os) dispersion fuel meats at an elevated temperature have been investigated. The volume increases of U-Mo compatibility specimens were almost the same as or smaller than those of U{sub 3}Si{sub 2}. However the atomized alloy fuel exhibited a better irradiation performance than the comminuted alloy. The RERTR-3 irradiation test of nano

    Full Text Available In this article, we focus on how various historical, contextual, and idiosyncratic factors shape the aims and methods of current European media educational practice. We start by briefly situating the history of European media education research and policymaking. We then discuss in more detail three important strands of media literacy initiatives within the Flemish Community (Belgium. While each of these diverging types of media education partly mirrors broader trends in European media research and policymaking, their aims and instructional methods also reveal the specificity of the Flemish media literacy context. In our discussion, we draw upon these findings to pinpoint a number of key determinants which may help to better understand similarities and differences within the European Union.

Ambiguity surrounding the potential risks intrinsic to social media could hinder ethical conduct and discourage use of this innovative method. We used some core principles of traditional human research ethics, that is, respect, integrity, and beneficence, to design our photo elicitation research that explored the social influences of drinking alcohol among 34 underage women in metropolitan South Australia. Facebook aided our communication with participants, including correspondence ranging from recruitment to feeding back results and sharing research data. This article outlines the ethical issues we encountered when using Facebook to interact with participants and provides guidance to researchers planning to incorporate social media as a tool in their qualitative studies. In particular, we raise the issues of privacy and confidentiality as contemporary risks associated with research using social media.

  1. Including Media in Field Research and Becoming Part of the Science Media

    Science.gov (United States)

    Pelto, M. S.

    2015-12-01

    There are two primary strategies that I have pursued over the last decade to engage the media, policy makers, and public; after two decades of typical scientific publication methods. An effective method to engage the media with our ongoing 32 year glacier field research program has been to invite media members to join us in the field. From climate videographers to traditional reporters we have had a member of the media with us in nine of the last ten field seasons; two in 2015. The resulting stories have led to several awards for the journalists and an ongoing relationship with our research program. The second part of this science research communication strategy is to have readily available material on specific topics for the media to utilize; this requires social media outreach. The primary outlet media find is the AGU Blog: From a Glacier's Perspective. This blog pubishes two articles a week on a specific glacier's response to climate change. The blog yields on average a media contact on every fourth blog post in 2015. The contacts revolve around specific local glacier information published on the blog. The goal of each blog post is to tell a story about how each glacier is impacted by climate change.

  9. Working the fringes: The role of letters to the editor in advancing non-standard media narratives about climate change.

    Science.gov (United States)

    Young, Nathan

    2013-05-01

    This article examines the role of letters to the editor in advancing and sustaining non-standard narratives about climate change in the print media. The letters page is a unique section of the newspaper that is subject to distinct functional and normative pressures. It is also a place where standard media norms are weakest and non-journalistic narratives have an opportunity to leak in. Using research into climate change coverage in eight major Canadian dailies in 2007-2008, the article employs content analysis and critical discourse analysis to examine how letters advance fringe arguments into the print media landscape that would not stand up to regular journalistic scrutiny. While these arguments come from all sides of the issue, it is argued that letters are particularly important for establishing and legitimizing conservative-skeptical perspectives on climate change.

  10. How Researchers Use Social Media to Promote their Research and Network with Industry

    Directory of Open Access Journals (Sweden)

    Päivi Jaring

    2017-08-01

    Full Text Available Social media is now an essential information and interaction channel. Companies advertise and sell their products and services through social media, but this channel has not been so commonly applied to the task of selling knowledge and research work. This article studies the use of social media by researchers to promote their research and network with product developers in industry, and it presents a model of the use of social media by researchers. The data for this research was obtained by interviewing individual researchers of a research organization and surveying product developers from industry. The findings show that social media is seen as a good source of new information and contacts, and it is suitable for promoting awareness of research services and results. The results show that the speed and intensity of social media present challenges for researchers, but by being active in posting content and participating in discussions, researchers can derive benefits and enhance their personal reputations.

    Joanna Górecka

    2011-01-01

    Full Text Available The aim of the paper is to discuss the relevance of media and information education in language learning at advanced levels. The present paper is based on the empirical data obtained during the action-research conducted with the Romance philology students attending the course of French as a foreign language. The main object of the research is to establish to what degree an oral argumentation task, preceded by the task of planning the discussion on Wiki is considered to be a learning situation by students themselves. The research focuses on a selected aspect of the learning process, namely, on the use of media resources while negotiating the discussion outline and specifically, while negotiating its topic, objectives and its cognitive value. The principal conclusions indicate 1 that the task scenario should be based on the critical and dialogical approach to media and 2 that this kind of instruction can reinforce the argumentative dimension of the discussion.

  12. Ethics of social media research: common concerns and practical considerations.

    Science.gov (United States)

    Moreno, Megan A; Goniu, Natalie; Moreno, Peter S; Diekema, Douglas

    2013-09-01

    Social media Websites (SMWs) are increasingly popular research tools. These sites provide new opportunities for researchers, but raise new challenges for Institutional Review Boards (IRBs) that review these research protocols. As of yet, there is little-to-no guidance regarding how an IRB should review the studies involving SMWs. The purpose of this article was to review the common risks inherent in social media research and consider how researchers can consider these risks when writing research protocols. We focused this article on three common research approaches: observational research, interactive research, and survey/interview research. Concomitant with these research approaches, we gave particular attention to the issues pertinent to SMW research, including privacy, consent, and confidentiality. After considering these challenges, we outlined key considerations for both researchers and reviewers when creating or reviewing SMW IRB protocols. Our goal in this article was to provide a detailed examination of relevant ethics and regulatory issues for both researchers and those who review their protocols.

  19. Youth and digital media: a policy research agenda.

    Science.gov (United States)

    Montgomery, K

    2000-08-01

    At a time when researchers are still sorting out the complex relationship between adolescents and the mass media, the entire nature of the media system is undergoing dramatic change. The explosive growth of the Internet is ushering in a new digital media culture. Youth are embracing the new technologies much more rapidly than adults. In addition, because of their increased spending power, youth have become a valuable target market for advertisers. These trends have spurred the proliferation of Web sites and other forms of new-media content specifically designed for teens and children. The burgeoning digital marketplace has spawned a new generation of market research companies, and market research on children and youth is outpacing academic research on youth and the newer media. The emergence of this new media culture holds both promise and peril for youth. Whether the positive or negative vision of the digital future prevails will be determined, in large part, by decisions being made now and in the next few years in the halls of government and in corporate boardrooms. Research has contributed to the resolutions of several recent legislative and policy decisions in areas including television violence and the V-chip, children's educational television programming, and privacy and marketing to children on the Web. Future research needs to be designed with the public policy agenda in mind. The academic community has much to contribute to the debates over new developments in the digital age.

  2. Beyond competence: advance directives in dementia research.

    Science.gov (United States)

    Jongsma, Karin Rolanda; van de Vathorst, Suzanne

    2015-01-01

    Dementia is highly prevalent and incurable. The participation of dementia patients in clinical research is indispensable if we want to find an effective treatment for dementia. However, one of the primary challenges in dementia research is the patients' gradual loss of the capacity to consent. Patients with dementia are characterized by the fact that, at an earlier stage of their life, they were able to give their consent to participation in research. Therefore, the phase when patients are still competent to decide offers a valuable opportunity to authorize research, by using an advance research directive (ARD). Yet, the use of ARDs as an authorization for research participation remains controversial. In this paper we discuss the role of autonomous decision-making and the protection of incompetent research subjects. We will show why ARDs are a morally defensible basis for the inclusion of this population in biomedical research and that the use of ARDs is compatible with the protection of incompetent research subjects.

  3. Ethical Considerations When Using Social Media for Research.

    Science.gov (United States)

    Hammer, Marilyn J

    2017-07-01

    Because of its adaptation across age groups and populations, social media is being used as a venue for the conduction of research studies. The implications for use of social media to streamline data collection and analyses to understand epidemiologic effects of disease are intriguing. Public access to personalized Internet-based searches and conversations for patients with or at risk for cancer can potentially allow providers to target individuals for earlier interventions and improved outcomes. Although publicly posted, the use of personal information to solicit research participants, implement interventions, or abstract information for research studies raises questions regarding maintaining the ethical conduct of research.

  4. NATO Advanced Research Workshop on Molecular Engineering for Advanced Materials

    CERN Document Server

    Schaumburg, Kjeld

    1995-01-01

    An important aspect of molecular engineering is the `property directed' synthesis of large molecules and molecular assemblies. Synthetic expertise has advanced to a state which allows the assembly of supramolecules containing thousands of atoms using a `construction kit' of molecular building blocks. Expansion in the field is driven by the appearance of new building blocks and by an improved understanding of the rules for joining them in the design of nanometer-sized devices. Another aspect is the transition from supramolecules to materials. At present no single molecule (however large) has been demonstrated to function as a device, but this appears to be only a matter of time. In all of this research, which has a strongly multidisciplinary character, both existing and yet to be developed analytical techniques are and will remain indispensable. All this and more is discussed in Molecular Engineering for Advanced Materials, which provides a masterly and up to date summary of one of the most challenging researc...

  10. The media go-along: Researching mobilities with media at hand

    Directory of Open Access Journals (Sweden)

    Kristian Møller Jørgensen

    2016-06-01

    Full Text Available This article contributes methodologically and theoretically to Christine Hine’s call for a mobilities oriented internet ethnography. First, a ‘media go-along’, combining interviews and observations of a personal communication service at hand, is developed. Research participants give verbal and visual tours, framed by the researcher’s discursively constituted invitations for orientation. Then, a theoretical framework integrating an analysis of media environment mobilities is developed. From research material on hook-up and dating apps targeting non-heterosexual men, it is shown how 1 research participants’ navigation is materially contingent upon the medium and subject to momentary purposes and styles, 2 researcher presence and access must regularly be re-inscribed discursively, and 3 mobile media analysis, based on the media go-along’s representations of verbal, material, affective, and kinetic aspects of social interaction, is useful in the analysis of socially-conditioned access to, and production of, single media practice and experience.

    Kuliasha, M. A.

    The Office of Building Energy Research and Development of the U.S. Department of Energy (DOE), has been funding R&D in advanced heat pumps and appliances since 1976. Much of that research has been managed for DOE by the Oak Ridge National Laboratory (ORNL). The objective of the Building Equipment Research (BER) program at ORNL has been to generate new concepts and develop a technology base for improving the energy efficiency and load characteristics of energy conversion equipment used in residential and commercial buildings. The research being pursued to achieve these objectives falls under three general areas: thermally activated heat pumps (TAHP), refrigeration systems, and building equipment systems. The TAHP work is concentrated on three technologies: (1) absorption heat pumps; (2) Stirling engine-driven heat pumps; and (3) internal combustion (IC) engine-driven heat pumps. Major project areas in refrigeration systems research include electric heat pumps, ground-coupled heat pumps, and refigerant mixtures. In the building equipment systems areas, project areas include advanced distribution systems, advanced insulation for appliances, and commercial building equipment.

    A comprehensive review of online, official, and scientific literature was carried out in 2012-13 to develop a framework of disaster social media. This framework can be used to facilitate the creation of disaster social media tools, the formulation of disaster social media implementation processes, and the scientific study of disaster social media effects. Disaster social media users in the framework include communities, government, individuals, organisations, and media outlets. Fifteen distinct disaster social media uses were identified, ranging from preparing and receiving disaster preparedness information and warnings and signalling and detecting disasters prior to an event to (re)connecting community members following a disaster. The framework illustrates that a variety of entities may utilise and produce disaster social media content. Consequently, disaster social media use can be conceptualised as occurring at a number of levels, even within the same disaster. Suggestions are provided on how the proposed framework can inform future disaster social media development and research.

    Full Text Available This article introduces an emerging area of qualitative media «audience» research, in which individuals are asked to produce media or visual material themselves, as a way of exploring their relationship with particular issues or dimensions of media. The process of making a creative visual artefact – as well as the artefact itself (which may be, for example, a video, drawing, collage, or imagined magazine cover – offers a reflective entry-point into an exploration of individuals» relationships with media culture. This article sets out some of the origins, rationale and philosophy underlying this methodological approach; briefly discusses two example studies (one in which children made videos to consider their relationship with the environment, and one in which young people drew pictures of celebrities as part of an examination of their aspirations and identifications with stars; and finally considers some emerging issues for further development of this method.

    The mission of the Advanced Energy Projects (AEP) program is to explore the scientific feasibility of novel energy-related concepts that are high risk, in terms of scientific feasibility, yet have a realistic potential for a high technological payoff. The concepts supported by the AEP are typically at an early stage of scientific development. They often arise from advances in basic research and are premature for consideration by applied research or technology development programs. Some are based on discoveries of new scientific phenomena or involve exploratory ideas that span multiple scientific and technical disciplines which do not fit into an existing DOE program area. In all cases, the objective is to support evaluation of the scientific or technical feasibility of the novel concepts involved. Following AEP support, it is expected that each concept will be sufficiently developed to attract further funding from other sources to realize its full potential. Projects that involve evolutionary research or technology development and demonstration are not supported by AEP. Furthermore, research projects more appropriate for another existing DOE research program are not encouraged. There were 65 projects in the AEP research portfolio during Fiscal Year 1997. Eigheen projects were initiated during that fiscal year. This document consists of short summaries of projects active in FY 1997. Further information of a specific project may be obtained by contacting the principal investigator.

    Up to this date, there are no reports made about the use of media for recruiting research volunteers in Latin American populations. Given the emergence of clinical research in Ecuador, a study of this kind in the local population will be beneficial for future research, and is probably applicable to other countries in the region. Two public calls were made for a cross-sectional study on cognitive function and diabetes. We only included people between 55 and 65 years of age without previous neurocognitive conditions. We invited individuals through interviews on the radio, television broadcasts and local newspapers, along with social media ads. Each individual was asked about the method by which they learned of the project. We calculated the frequency in which each method was reported and a chi-square test was used to assess gender differences in the results. A total of 274 patients were enrolled in the study, 64.2% are women and 35.8% men. We found that 29.93% learned of it from third persons, 20.8% through radio, 8.76% through social media, 8.39% by newspaper, and 5.11% by television, while a remaining 27.01% had not previously heard of the recruitment call. Methods reported varied significantly between men and women (p = 0.03). Traditional media were the most common method of recruitment, with radio interviews being the most frequently reported. Individually, none of them surpassed the frequency of people learning of the project from other people (snowball effect). Social networks play an important role, exceeding certain traditional media. We have described for the first time in Latin America the use of media as methods to recruit volunteers for research, and the importance of project dissemination by the participants to reach more people.

    As the United States moves forward with health reform, the communication gap between researchers and policy makers will need to be narrowed to promote policies informed by evidence. Social media represent an expanding channel for communication. Academic journals, public health agencies, and health care organizations are increasingly using social media to communicate health information. For example, the Centers for Disease Control and Prevention now regularly tweets to 290,000 followers. We conducted a survey of health policy researchers about using social media and two traditional channels (traditional media and direct outreach) to disseminate research findings to policy makers. Researchers rated the efficacy of the three dissemination methods similarly but rated social media lower than the other two in three domains: researchers' confidence in their ability to use the method, peers' respect for its use, and how it is perceived in academic promotion. Just 14 percent of our participants reported tweeting, and 21 percent reported blogging about their research or related health policy in the past year. Researchers described social media as being incompatible with research, of high risk professionally, of uncertain efficacy, and an unfamiliar technology that they did not know how to use. Researchers will need evidence-based strategies, training, and institutional resources to use social media to communicate evidence.

    Important advances have been made in the field of geochemistry since nanometer science and technology were introduced into the field of geoscience. The nanometer particulates have been discovered in naturally-occurring ore deposits, volcano-eruptive materials and geo-gases, and a more detailed exploration of the metallogenic mechanism of endogenic metallic ore deposits has been conducted. It is considered that some ore-forming metals may transport in the form of native particulates. Because they have very strong capabilities of adsorption, adsorption is always regarded as an important mechanism of metallogenesis under supergenic and low temperature conditions.Therefore, a new technology of ore exploration has also been developed. This paper attempts to review the new advances in geochemical research on nanometer materials, as well as its perspectivess.

    Cerebral palsy is a group of syndromes caused by non-progressive brain injury in the fetus or infant and can cause disabilities in childhood. Etiology of cerebral palsy has always been a hot topic for clinical scientists. More and more studies have shown that genetic factors are closely associated with the development of cerebral palsy. With the development and application of various molecular and biological techniques such as chromosome microarray analysis, genome-wide association study, and whole exome sequencing, new achievements have been made in the genetic research of cerebral palsy. Chromosome abnormalities, copy number variations, susceptibility genes, and single gene mutation associated with the development of cerebral palsy have been identified, which provides new opportunities for the research on the pathogenesis of cerebral palsy. This article reviews the advances in the genetic research on cerebral palsy in recent years.

    Advancing biomedical knowledge is crucial to the understanding of disease pathophysiology, diagnosis, treatment, and the maintenance of health. Whereas collaborative pursuits among basic and translational scientists, clinical researchers, and clinicians should advance biomedical progress and its translation to better medicine. The field of obstetrics and gynecology and its subspecialties has not escaped this problem. Obstetrics and gynecology specialists and subspecialists have limited opportunities to interact with translational or basic investigators, and cross-fertilization and collaborations are further challenged by the current healthcare and funding climate. This opinion manuscript focuses on the field of maternal-fetal medicine, serving as an example that illustrates the risks and opportunities that might exist within our obstetrics and gynecology academic community. A Pregnancy Task Force recently sought to identify ways to overcome hurdles related to research training, and ensure a sufficient pool of physician-scientists pursuing pertinent questions in the field. The group discussed strategies to promote a culture of intellectual curiosity and research excellence, securing additional resources for trainees, and attracting current and next generation basic, translational, and clinical scholars to our field. Recommendations encompassed activities within annual academic meetings, training initiatives, and additional funding opportunities. Inferences from these discussions can be made to all obstetrics and gynecology subspecialty areas. Copyright © 2014 Mosby, Inc. All rights reserved.

    Elson, Bruce; Reynolds, Patricia; Amini, Ardavan; Burke, Ezra; Chapman, Craig

    There is growing demand for dental education and training not only in terms of knowledge but also skills. This demand is driven by continuing professional development requirements in the more developed economies, personnel shortages and skills differences across the European Union (EU) accession states and more generally in the developing world. There is an excellent opportunity for the EU to meet this demand by developing an innovative online flexible learning platform (FLP). Current clinical online systems are restricted to the delivery of general, knowledge-based training with no easy method of personalization or delivery of skill-based training. The PHANTOM project, headed by Kings College London is developing haptic-based virtual reality training systems for clinical dental training. ANDROMEDA seeks to build on this and establish a Flexible Learning Platform that can integrate the haptic and sensor based training with rich media knowledge transfer, whilst using sophisticated technologies such as including service-orientated architecture (SOA), Semantic Web technologies, knowledge-based engineering, business intelligence (BI) and virtual worlds for personalization.

    Health care in the United States is facing a crisis in providing access to quality care for those in underserved and rural regions. Advanced practice nurses are at the forefront of addressing such issues, through modalities such as health care technology. Many nursing education programs are seeking strategies for better educating students on technology utilization. Health care technology includes electronic health records, telemedicine, and clinical decision support systems. However, little focus has been placed on the role of social media in health care. This paper describes an educational workshop using standardized patients and hands-on experiences to introduce advanced practice nurses in a Doctor of Nursing Practice program to the role of social media in addressing issues inherent in the delivery of rural health care. The students explore innovative approaches for utilizing social media for patient and caregiver support as well as identify online resources that assist providers in a rural setting.

    Today's scientists need access to new information technology capabilities, able to perform high-resolution complex computing simulations in a reasonable time frame. Sophisticated simulation tools allow us to study phenomena that can never be observed or replicated by standard laboratory experiments. Modeling complex natural processes in general, and numerical computation in particular, represents today an essential need of research, and all modern research centers benefit from a computing center of one form or another. The combined power of hardware and sophisticated software, visualization tools, and scientific applications produced and used by interdisciplinary research teams make possible nowadays to advance the frontiers of science and to pose new key scientific questions. Cyberinfrastructure integrates hardware for high speed computing, a collection of highly specialized software and tools, and a powerful visualization tool. A new interdisciplinary research domain is emerging at the interface of geosciences and computing with essential inputs from geology and geophysics. In this study we show how to rapidly deploy a low-cost high-performance computing cluster (HPCC) and a 3D visualization system that can be used both in teaching and research in geosciences. Also, we present several geodynamic simulations performed with such systems.

    The first geothermal application of the Advanced Direct Contact Condenser (ADCC) technology developed by the National Renewable Energy Laboratory (NREL) is now operational and is being tested at The Geysers Power Plant Unit 11. This major research effort is being supported through the combined efforts of NREL, The Department of Energy (DOE), and Pacific Gas and Electric (PG&E). NREL and PG&E have entered into a Cooperative Research And Development Agreement (CRADA) for a project to improve the direct-contact condenser performance at The Geysers Power Plant. This project is the first geothermal adaptation of an advanced condenser design developed for the Ocean Thermal Energy Conversion (OTEC) systems. PG&E expects this technology to improve power plant performance and to help extend the life of the steam field by using steam more efficiently. In accordance with the CRADA, no money is transferred between the contracting parties. In this case the Department of Energy is funding NREL for their efforts in this project and PG&E is contributing funds in kind. Successful application of this technology at The Geysers will provide a basis for NREL to continue to develop this technology for other geothermal and fossil power plant systems.

    Bernardo, Theresa M; Malinowski, Robert P

    2005-01-01

    In this article, advances in the application of medical media to education, clinical care, and research are explored and illustrated with examples, and their future potential is discussed. Impact is framed in terms of the Sloan Consortium's five pillars of quality education: access; student and faculty satisfaction; learning effectiveness; and cost effectiveness. (Hiltz SR, Zhang Y, Turoff M. Studies of effectiveness of learning networks. In Bourne J, Moore J, ed. Elements of Quality Online Education. Needham, MA: Sloan-Consortium, 2002:15-45). The alternatives for converting analog media (text, photos, graphics, sound, video, animations, radiographs) to digital media and direct digital capture are covered, as are options for storing, manipulating, retrieving, and sharing digital collections. Diagnostic imaging is given particular attention, clarifying the difference between computerized radiography and digital radiography and explaining the accepted standard (DICOM) and the advantages of Web PACS. Some novel research applications of medical media are presented.

    Background Otitis media (OM) is the most common childhood bacterial infection and also the leading cause of conductive hearing loss in children. Currently, there is an urgent need for developing novel therapeutic agents for treating OM based on full understanding of molecular pathogenesis in the areas of molecular biology, biochemistry, genetics, and animal model studies in OM. Objective To provide a state-of-the-art review concerning recent advances in OM in the areas of molecular biology, biochemistry, genetics, and animal model studies and to discuss the future directions of OM studies in these areas. Data Sources and Review Methods A structured search of the current literature (since June 2007). The authors searched PubMed for published literature in the areas of molecular biology, biochemistry, genetics, and animal model studies in OM. Results Over the past 4 years, significant progress has been made in the areas of molecular biology, biochemistry, genetics, and animal model studies in OM. These studies brought new insights into our understanding of the molecular and biochemical mechanisms underlying the molecular pathogenesis of OM and helped identify novel therapeutic targets for OM. Conclusions and Implications for Practice Our understanding of the molecular pathogenesis of OM has been significantly advanced, particularly in the areas of inflammation, innate immunity, mucus overproduction, mucosal hyperplasia, middle ear and inner ear interaction, genetics, genome sequencing, and animal model studies. Although these studies are still in their experimental stages, they help identify new potential therapeutic targets. Future preclinical and clinical studies will help to translate these exciting experimental research findings into clinical applications. PMID:23536532

  12. Translating Research for Health Policy Decisions: Is It Time for Researchers to Join Social Media?

    Meisel, Zachary F; Gollust, Sarah E; Grande, David

    2016-10-01

    Identifying effective strategies to translate research evidence to policy is a national priority and a priority of the health policy research community. Multiple channels exist to disseminate, translate, and communicate research evidence. Some thought leaders have specifically advocated for researchers to play a direct role in research dissemination, particularly through social media. However, this view remains controversial. This Commentary explores the current state of and future opportunities and barriers for alternative avenues of policy-relevant research dissemination. The authors identify four intersecting realities influencing the manner in which the health research community views and adopts various approaches to research translation: (1) persistent gaps in evidence translation and knowledge transfer, particularly in the realm of health policy; (2) public demand for scholars to embrace new modes of research dissemination; (3) the rapid growth and reach of social media to disseminate information; and (4) skepticism and confusion within the academic community about how best to use social media to disseminate policy-relevant research. They conclude that while scholars will need to be engaged in evidence translation to inform health policy, they may be best served by connecting with trusted intermediaries and knowledge brokers to promote efficient use of the best available evidence to answer the most timely policy questions. Journals and universities may be well positioned to invest in this capacity to curate research evidence and disseminate it using social media and other technologies.

  16. Organics, trust, and credibility: a management and media research perspective

    Directory of Open Access Journals (Sweden)

    Iris Rittenhofer

    2015-03-01

    Full Text Available Our purpose was to qualify the relations between trust, credibility, and the field of organics by way of creating a dialogue between two independent Organic Research, Development and Demonstration Programme "MultiTrust" subprojects. Both projects explore the explanatory value of trust and credibility for the success of organic labels in the fields of management research and media research. Our key objectives were to critically scrutinize the trust and credibility constructs applied in each of these two fields, to reflect on their explanatory value in the performance of organics from both a management and media perspective, and to set out an agenda for future interdisciplinary research. We conclude that relations between organic products, labels, and consumers are still poorly understood, that the belief in organic labels' direct impact on consumer choices in favor of organic food purchase cannot be supported, and that the explanatory value of trust for the success of organic production remains unproven. We propose for future research to investigate the relevance of credibility and trust for organics in multidisciplinary mixed-methods studies that focus on the emergence of trust, as well as on other social factors impacting the success of organic production. This would best be achieved through interdisciplinary work.

    2014-03-01

    To examine the current data supporting use of social media in breast cancer clinical care. Although opportunities to utilize social media to increase knowledge have been commonly seized, the opportunity to improve communication among clinicians is lagging. Locally advanced breast cancer (LABC) requires timely coordination of care among many specialists, and presents an excellent scenario for enhanced utilization of current IT strategies. A systematic review was conducted to assess the use of social media to enhance breast cancer care. In addition, a Web-based search using common search engines and publicly available social media was conducted to determine the prevalence of information and networking pages aimed at patients and clinicians. Over 400 articles were retrieved; 81% focused on delivery of information or online support to patients, 17% focused on delivery of information to physicians, and 1% focused on the use of social media to improve collaboration among clinicians. Web searches retrieved millions of hits, with very few hits relating to improving collaboration among clinicians. Although there is significant potential to utilize current technologies to improve care for patients and improve connectedness among clinicians, most of the currently available technologies focus solely on the delivery of information.

  20. Advances in Mycotoxin Research: Public Health Perspectives.

    Science.gov (United States)

    Lee, Hyun Jung; Ryu, Dojin

    2015-12-01

    Aflatoxins, ochratoxins, fumonisins, deoxynivalenol, and zearalenone are of significant public health concern as they can cause serious adverse effects in different organs including the liver, kidney, and immune system in humans. These toxic secondary metabolites are produced by filamentous fungi mainly in the genus Aspergillus, Penicillium, and Fusarium. It is challenging to control the formation of mycotoxins due to the worldwide occurrence of these fungi in food and the environment. In addition to raw agricultural commodities, mycotoxins tend to remain in finished food products as they may not be destroyed by conventional processing techniques. Hence, much of our concern is directed to chronic health effects through long-term exposure to one or multiple mycotoxins from contaminated foods. Ideally risk assessment requires a comprehensive data, including toxicological and epidemiological studies as well as surveillance and exposure assessment. Setting of regulatory limits for mycotoxins is considered necessary to protect human health from mycotoxin exposure. Although advances in analytical techniques provide basic yet critical tool in regulation as well as all aspects of scientific research, it has been acknowledged that different forms of mycotoxins such as analogs and conjugated mycotoxins may constitute a significant source of dietary exposure. Further studies should be warranted to correlate mycotoxin exposure and human health possibly via identification and validation of suitable biomarkers.

  1. Eagleworks Laboratories: Advanced Propulsion Physics Research

    Science.gov (United States)

    White, Harold; March, Paul; Williams, Nehemiah; ONeill, William

    2011-01-01

    NASA/JSC is implementing an advanced propulsion physics laboratory, informally known as "Eagleworks", to pursue propulsion technologies necessary to enable human exploration of the solar system over the next 50 years, and enabling interstellar spaceflight by the end of the century. This work directly supports the "Breakthrough Propulsion" objectives detailed in the NASA OCT TA02 In-space Propulsion Roadmap, and aligns with the #10 Top Technical Challenge identified in the report. Since the work being pursued by this laboratory is applied scientific research in the areas of the quantum vacuum, gravitation, nature of space-time, and other fundamental physical phenomenon, high fidelity testing facilities are needed. The lab will first implement a low-thrust torsion pendulum (physics and engineering models can be explored and understood in the lab to allow scaling to power levels pertinent for human spaceflight, 400kW SEP human missions to Mars may become a possibility, and at power levels of 2MW, 1-year transit to Neptune may also be possible. Additionally, the lab is implementing a warp field interferometer that will be able to measure spacetime disturbances down to 150nm. Recent work published by White [1] [2] [3] suggests that it may be possible to engineer spacetime creating conditions similar to what drives the expansion of the cosmos. Although the expected magnitude of the effect would be tiny, it may be a "Chicago pile" moment for this area of physics.

  2. [Research advances on interactions among bryophytes].

    Bu, Zhao-Jun; Chen, Xu; Jiang, Li-Hong; Li, Hong-Kai; Zhao, Hong-Yan

    2009-02-01

    This paper summarized the present research status and advances on the intra- and interspecific positive interaction, intra- and inter-specific competition, niche, and coexistence of bryophytes. Bryophytes are generally the dominant plants in harsh environments, and there is a trade-off between their water retention and light and nutrient resource availability. Because of the lesser importance of competition in harsh environments, the positive interaction among bryophytes is common, but the intra- and inter-specific competition among bryophytes and the competition between bryophytes and vascular plants are not rare. Competition hierarchy may exist among some bryophytes, but often changes with environments. In the process of bryophyte community formation, the random process, nature of colonization, and difference in regeneration strategy can result in the niche overlap and coexistence of bryophytes, and the niche differentiation resulted from competition is also one of the mechanisms for bryophytes coexistence. Bryophytes should not be simply classified as stress tolerated-ruderal life history strategists, and competition is still one of important factors for constructing some bryophyte communities and vegetations co-existed by bryophytes and vascular plants.

    1999-01-28

    The Advanced Research Workshop (ARW) on Nuclear Materials Safety held June 8-10, 1998, in St. Petersburg, Russia, was attended by 27 Russian experts from 14 different Russian organizations, seven European experts from six different organizations, and 14 U.S. experts from seven different organizations. The ARW was conducted at the State Education Center (SEC), a former Minatom nuclear training center in St. Petersburg. Thirty-three technical presentations were made using simultaneous translations. These presentations are reprinted in this volume as a formal ARW Proceedings in the NATO Science Series. The representative technical papers contained here cover nuclear material safety topics on the storage and disposition of excess plutonium and high enriched uranium (HEU) fissile materials, including vitrification, mixed oxide (MOX) fuel fabrication, plutonium ceramics, reprocessing, geologic disposal, transportation, and Russian regulatory processes. This ARW completed discussions by experts of the nuclear materials safety topics that were not covered in the previous, companion ARW on Nuclear Materials Safety held in Amarillo, Texas, in March 1997. These two workshops, when viewed together as a set, have addressed most nuclear material aspects of the storage and disposition operations required for excess HEU and plutonium. As a result, specific experts in nuclear materials safety have been identified, know each other from their participation in t he two ARW interactions, and have developed a partial consensus and dialogue on the most urgent nuclear materials safety topics to be addressed in a formal bilateral program on t he subject. A strong basis now exists for maintaining and developing a continuing dialogue between Russian, European, and U.S. experts in nuclear materials safety that will improve the safety of future nuclear materials operations in all the countries involved because of t he positive synergistic effects of focusing these diverse backgrounds of

  6. From digital positivism and administrative big data analytics towards critical digital and social media research!

    OpenAIRE

    Fuchs, Christian

    2017-01-01

    This essay argues for a paradigm shift in the study of the Internet and digital/social media. Big data analytics is the dominant paradigm. It receives large amounts of funding, is administrative and a form of digital positivism. Critical social media research is an alternative approach that combines critical social media theory, critical digital methods and critical-realist social media research ethics. Strengthening the second approach is a material question of power in academia.

  8. The impact of electronic media violence: scientific theory and research.

    Science.gov (United States)

    Huesmann, L Rowell

    2007-12-01

    Since the early 1960s, research evidence has been accumulating that suggests that exposure to violence in television, movies, video games, cell phones, and on the Internet increases the risk of violent behavior on the viewer's part, just as growing up in an environment filled with real violence increases the risk of them behaving violently. In the current review this research evidence is critically assessed and the psychological theory that explains why exposure to violence has detrimental effects for both the short and long-term is elaborated. Finally the size of the "media violence effect" is compared with some other well-known threats to society to estimate how important a threat it should be considered.

  9. Survey of cogeneration: Advanced cogeneration research study

    1983-01-01

    The consumption of electricity, natural gas, or fuel oil was surveyed. The potential electricity that could be generated in the SCE service territory using cogeneration technology was estimated. It was found that an estimated 3700 MWe could potentially be generated in Southern California using cogenerated technology. It is suggested that current technology could provide 2600 MWe and advanced technology could provide 1100 MWe. Approximately 1600 MWt is considered not feasible to produce electricity with either current or advanced cogeneration technology.

    2016-03-01

    Scientific media education is the ability to draw on a knowledge of the media and science, in order to choose, understand, evaluate, and respond to representations of science across diverse media genres. We begin this manuscript by reviewing research that shows scientific media education is one of the most important content areas that could be taught in and out of the science classroom. We then set out to identify a research agenda that will help make scientific media education a key content area in both formal and informal science learning environments. In particular, we identified research avenues that will allow us to better understand: (1) limitations in current practices of scientific media education; (2) what scientific media education should look like in the future; and (3) ways we might overcome barriers to implementing a new and improved scientific media education.

  16. Experimental development of advanced air filtration media based on electrospun polymer fibers

    Science.gov (United States)

    Ghochaghi, Negar

    Electrospinning is a process by which polymer fibers can be produced using an electrostatically driven fluid jet. Electrospun fibers can be produced at the micro- or nano-scale and are, therefore, very promising for air filtration applications. However, because electrospun fibers are electrically charged, it is difficult to control the morphology of filtration media. Fiber size, alignment and uniformity are very important factors that affect filter performance. The focus of this project is to understand the relationship between filter morphology and performance and to develop new methods to create filtration media with optimum morphology. This study is divided into three focus areas: unimodal and bimodal microscale fibrous media with aligned, orthogonal and random fiber orientations; unimodal and bimodal nanoscale fibers in random orientations; bimodal micrometer and nanometer fiber media with orthogonally aligned orientations. The results indicate that the most efficient filters, which are those with the highest ratio of particle collection efficiency divided by pressure drop, can be obtained through fabricating filters in orthogonal layers of aligned fibers with two different fiber diameters. Moreover, our results show that increasing the number of layers increases the performance of orthogonally layered fibers. Also, controlling fiber spacing in orthogonally layered micrometer fiber media can be an alternative way to study the filtration performance. Finally, such coatings presented throughout this research study can be designed and placed up-stream, down-stream, and/or in between conventional filters.

  17. Researching Social Media as if the Social Mattered

    Directory of Open Access Journals (Sweden)

    Nick Couldry

    2015-09-01

    Full Text Available The institutions we have come to call “media” have been involved for over a century in providing an infrastructure for social life and have invested in a quite particular and privileged way of re-presenting the world as “social.” The dialectic between “media” and “social” has become more urgent to understand in an era when media and information infrastructures have expanded, converged, and become embedded more deeply in the texture of everyday life, while at the same time the claims of “media” to be social have become explicit, indeed insistent. This article asks what it would mean to address this new social/media dialectic head on—as if the social mattered. The word “social” is our necessary term for thinking about the complex interdependencies out of which human life really is made and the claims to represent that interdependent reality made from particular positions of power. All forms of power have invested in certain representations of the social. This battle matters, and now “social media”—the infrastructures of web 2.0—are at the heart of that battle. The article seeks to offer a plausible agenda for a collaborative program of research to address this struggle over the definition of “the social.”

    Dhar, Nibir K.; Dat, Ravi

    2012-06-01

    Advances in imaging technology have huge impact on our daily lives. Innovations in optics, focal plane arrays (FPA), microelectronics and computation have revolutionized camera design. As a result, new approaches to camera design and low cost manufacturing is now possible. These advances are clearly evident in visible wavelength band due to pixel scaling, improvements in silicon material and CMOS technology. CMOS cameras are available in cell phones and many other consumer products. Advances in infrared imaging technology have been slow due to market volume and many technological barriers in detector materials, optics and fundamental limits imposed by the scaling laws of optics. There is of course much room for improvements in both, visible and infrared imaging technology. This paper highlights various technology development projects at DARPA to advance the imaging technology for both, visible and infrared. Challenges and potentials solutions are highlighted in areas related to wide field-of-view camera design, small pitch pixel, broadband and multiband detectors and focal plane arrays.

  3. The Need for Interdisciplinary Research of the Arab Mass Media

    Directory of Open Access Journals (Sweden)

    Mohammad Ayish

    2014-12-01

    Full Text Available This paper critically reviews mainstream models of mass communication research in the Arab world and proposes an interdisciplinary perspective that addresses communication within a broader theoretical and analytical framework. Scholarly works on 20th century Arab mass communication can be placed in six subject categories: propaganda, development communication, historical accounts, international news flow, technical and professional works, and general theoretical works (Ayish, 1998. Recent significant technological, political, and social developments have redefined not only perspectives about the Arab world’s transitions, but also about how mass communications contribute to this change. The paper subsequently examines three research areas of particular relevance to scholarship of media usage within, and of the Arab world. The first is concerned with the political economy of flow, a global apparatus of systems of movement of people, ideas and cultural products, financial instruments, and goods. The second area is concerned with the study of the rapidly increasing mobility of subjects that is a phenomenon of the political economic apparatus of flow and that has changed the context within which the Arab mass media are both disseminated and consumed. Lastly, the paper discusses the relevance of this work to the changing nature of the production of identity. Here the authors describe identity as a contingent phenomenon that is determined by a host of political, economic, social, cultural, and other factors that delineate the production of one’s sense of self, while arguing that the articulation of the political economic apparatus of flow has rearticulated the relationships amongst the factors that identity draws upon and is demarcated by.

  4. Human life, media and market: a sociotechnical perspective of research with embryonic stem cells

    Directory of Open Access Journals (Sweden)

    Júlio Cesar de Almeida Nobre

    2014-04-01

    Full Text Available New biotechnologies of reproduction emerge nowadays as radical destabilizing agents of what we understand as human life. Within this context, research involving stem cells are on the agenda of several academic articles and major newspapers and magazines around the world. The arguments vary from a sort of pride about the emancipatory power of technology to a fear about the absence of limits to restrict undesirable advances. Amid such controversies, our proposal is, based on Actor Network Theory, to draw a map of networks that produce what we understand as human life, insofar as it seems to be unstabled by the new biotechnologies of reproduction. We followed different mediators along their deviations, in order to produce a report based on the analysis of current bioethical controversies involving, specifically, embryonic stem cell research. These controversies led to a strong connection between media, new biotechnologies of human reproduction and a market logic.

    Major developments, as well as remaining challenges and the associated research opportunities, are evaluated for three technologically distinct approaches to solar energy utilization: solar electricity, solar thermal, and solar fuels technologies. Much progress has been made, but research opportunities are still present for all approaches. Both evolutionary and revolutionary technology development, involving foundational research, applied research, learning by doing, demonstration projects, and deployment at scale will be needed to continue this technology-innovation ecosystem. Most of the approaches still offer the potential to provide much higher efficiencies, much lower costs, improved scalability, and new functionality, relative to the embodiments of solar energy-conversion systems that have been developed to date.

    Full Text Available The 21st century has marked an unprecedented advancement of new media. New media has become so pervasive that it has penetrated into every aspect of our society. New media literacy plays an essential role for any citizen to participate fully in the 21st century society. Researchers have documented that literacy has evolved historically from classic literacy (reading-writing-understanding to audiovisual literacy to digital literacy or information literacy and recently to new media literacy. A review of literature on media literacy reveals that there is a lack of thorough analysis of unique characteristics of new media and its impacts upon the notion of new media literacy. The purpose of the study is to unpack new media literacy and propose a framework for a systematic investigation of new media literacy.

    Full Text Available Digital media and network communication technology have not changed this setup, but rather have opened the possibility for encountering and experiencing additional types of worlds and performing additional types of spatial practices. Being situated online and being globally networked with the possibility of both synchronous and asynchronous communication, digitally mediated worlds provide possible interactions between users which are radically more independent of time and place than the ones facilitated by older media. From this perspective, the concept of online worlds both challenges and broadens our understanding of how media shape the world and how the media technology creates new social structures.

  4. A call for innovative social media research in the field of augmentative and alternative communication.

    Science.gov (United States)

    Hemsley, Bronwyn; Balandin, Susan; Palmer, Stuart; Dann, Stephen

    2017-03-01

    Augmentative and alternative communication (AAC) social media research is relatively new, and is built on a foundation of research on use of the Internet and social media by people with communication disabilities. Although the field is expanding to include a range of people who use AAC, there are limitations and gaps in research that will need to be addressed in order to keep pace with the rapid evolution of social media connectivity in assistive communication technologies. In this paper, we consider the aims, scope, and methodologies of AAC social media research, with a focus on social network sites. Lack of detailed attention to specific social network sites and little use of social media data limits the extent to which findings can be confirmed. Increased use of social media data across a range of platforms, including Instagram and YouTube, would provide important insights into the lives of people who use AAC and the ways in which they and their supporters use social media. New directions for AAC social media research are presented in line with those discussed at the social media research symposium at the International Society for Augmentative and Alternative Communication in Toronto, Canada, on August 12, 2016.

    SCHLEYER, TITUS; BUTLER, BRIAN S.; SONG, MEI; SPALLEK, HEIKO

    2013-01-01

    Science in general, and biomedical research in particular, is becoming more collaborative. As a result, collaboration with the right individuals, teams, and institutions is increasingly crucial for scientific progress. We propose Research Networking Systems (RNS) as a new type of system designed to help scientists identify and choose collaborators, and suggest a corresponding research agenda. The research agenda covers four areas: foundations, presentation, architecture, and evaluation. Foundations includes project-, institution- and discipline-specific motivational factors; the role of social networks; and impression formation based on information beyond expertise and interests. Presentation addresses representing expertise in a comprehensive and up-to-date manner; the role of controlled vocabularies and folksonomies; the tension between seekers’ need for comprehensive information and potential collaborators’ desire to control how they are seen by others; and the need to support serendipitous discovery of collaborative opportunities. Architecture considers aggregation and synthesis of information from multiple sources, social system interoperability, and integration with the user’s primary work context. Lastly, evaluation focuses on assessment of collaboration decisions, measurement of user-specific costs and benefits, and how the large-scale impact of RNS could be evaluated with longitudinal and naturalistic methods. We hope that this article stimulates the human-computer interaction, computer-supported cooperative work, and related communities to pursue a broad and comprehensive agenda for developing research networking systems.

    Golder, Su; Ahmed, Shahd; Norman, Gill; Booth, Andrew

    2017-06-06

    Although primarily used for social networking and often used for social support and dissemination, data on social media platforms are increasingly being used to facilitate research. However, the ethical challenges in conducting social media research remain of great concern. Although much debated in the literature, it is the views of the public that are most pertinent to inform future practice. The aim of our study was to ascertain attitudes on the ethical considerations of using social media as a data source for research as expressed by social media users and researchers. A systematic review was conducted, wherein 16 databases and 2 Internet search engines were searched in addition to handsearching, reference checking, citation searching, and contacting authors and experts. Studies that conducted any qualitative methods to collect data on attitudes on the ethical implications of research using social media were included. Quality assessment was conducted using the quality of reporting tool (QuaRT) and findings analyzed using inductive thematic synthesis. In total, 17 studies met the inclusion criteria. Attitudes varied from overly positive with people expressing the views about the essential nature of such research for the public good, to very concerned with views that social media research should not happen. Underlying reasons for this variation related to issues such as the purpose and quality of the research, the researcher affiliation, and the potential harms. The methods used to conduct the research were also important. Many respondents were positive about social media research while adding caveats such as the need for informed consent or use restricted to public platforms only. Many conflicting issues contribute to the complexity of good ethical practice in social media research. However, this should not deter researchers from conducting social media research. Each Internet research project requires an individual assessment of its own ethical issues

    2007-05-09

    A fundamental goal of the U.S. National Institute of Health (NIH) "Roadmap" is to strengthen Translational Research, defined as the movement of discoveries in basic research to application at the clinical level. A significant barrier to translational research is the lack of uniformly structured data across related biomedical domains. The Semantic Web is an extension of the current Web that enables navigation and meaningful use of digital resources by automatic processes. It is based on common formats that support aggregation and integration of data drawn from diverse sources. A variety of technologies have been built on this foundation that, together, support identifying, representing, and reasoning across a wide range of biomedical data. The Semantic Web Health Care and Life Sciences Interest Group (HCLSIG), set up within the framework of the World Wide Web Consortium, was launched to explore the application of these technologies in a variety of areas. Subgroups focus on making biomedical data available in RDF, working with biomedical ontologies, prototyping clinical decision support systems, working on drug safety and efficacy communication, and supporting disease researchers navigating and annotating the large amount of potentially relevant literature. We present a scenario that shows the value of the information environment the Semantic Web can support for aiding neuroscience researchers. We then report on several projects by members of the HCLSIG, in the process illustrating the range of Semantic Web technologies that have applications in areas of biomedicine. Semantic Web technologies present both promise and challenges. Current tools and standards are already adequate to implement components of the bench-to-bedside vision. On the other hand, these technologies are young. Gaps in standards and implementations still exist and adoption is limited by typical problems with early technology, such as the need for a critical mass of practitioners and installed base

    In recent years, with the development of genetics molecular biology and plant biotechnology, the vaccination (e.g. genetic engineering subunit vaccine, living vector vaccine, nucleic acid vaccine) programs are taking on a prosperous evolvement. In particular, the technology of the use of transgenic plants to produce human or animal therapeutic vaccines receives increasing attention. Expressing vaccine candidates in vegetables and fruits open up a new avenue for producing oral/edible vaccines. Transgenic plant vaccine disquisitions exhibit a tempting latent exploiting foreground. There are a lot of advantages for transgenic plant vaccines, such as low cost, easiness of storage, and convenient immune-inoculation. Some productions converged in edible tissues, so they can be consumed directly without isolation and purification. Up to now, many transgenic plant vaccine productions have been investigated and developed. In this review, recent advances on plant-derived recombinant protein expression systems, infectious targets, and delivery systems are presented. Some issues of high concern such as biosafety and public health are also discussed. Special attention is given to the prospects and limitations on transgenic plant vaccines.

    Qualitative methods have long been a part of health education research, but how qualitative approaches advance health equity has not been well described. Qualitative research is an increasingly important methodologic tool to use in efforts to understand, inform, and advance health equity. Qualitative research provides critical insight into the subjective meaning and context of health that can be essential for understanding where and how to intervene to inform health equity research and practice. We describe the larger context for this special theme issue of Health Education & Behavior, provide brief overviews of the 15 articles that comprise the issue, and discuss the promise of qualitative research that seeks to contextualize and illuminate answers to research questions in efforts to promote health equity. We highlight the critical role that qualitative research can play in considering and incorporating a diverse array of contextual information that is difficult to capture in quantitative research.

As a nematode, C. elegans have ~65% similarity with human disease genes and, therefore, studies on C. elegans can be translated to human, as well as, C. elegans can be used in the study of different types of parasitic worms that infect other living organisms. In the past decade, many efforts have been undertaken to establish interdisciplinary research collaborations between biologists, physicists and engineers in order to develop microfluidic devices to study the biology of C. elegans. Microfluidic devices with the power to manipulate and detect bio-samples, regents or biomolecules in micro-scale environments can well fulfill the requirement to handle worms under proper laboratory conditions, thereby significantly increasing research productivity and knowledge. The recent development of different kinds of microfluidic devices with ultra-high throughput platforms has enabled researchers to carry out worm population studies. Microfluidic devices primarily comprises of chambers, channels and valves, wherein worms can be cultured, immobilized, imaged, etc. Microfluidic devices have been adapted to study various worm behaviors, including that deepen our understanding of neuromuscular connectivity and functions. This review will provide a clear account of the vital involvement of microfluidic devices in worm biology.

    Full Text Available Abstract Background A fundamental goal of the U.S. National Institute of Health (NIH "Roadmap" is to strengthen Translational Research, defined as the movement of discoveries in basic research to application at the clinical level. A significant barrier to translational research is the lack of uniformly structured data across related biomedical domains. The Semantic Web is an extension of the current Web that enables navigation and meaningful use of digital resources by automatic processes. It is based on common formats that support aggregation and integration of data drawn from diverse sources. A variety of technologies have been built on this foundation that, together, support identifying, representing, and reasoning across a wide range of biomedical data. The Semantic Web Health Care and Life Sciences Interest Group (HCLSIG, set up within the framework of the World Wide Web Consortium, was launched to explore the application of these technologies in a variety of areas. Subgroups focus on making biomedical data available in RDF, working with biomedical ontologies, prototyping clinical decision support systems, working on drug safety and efficacy communication, and supporting disease researchers navigating and annotating the large amount of potentially relevant literature. Results We present a scenario that shows the value of the information environment the Semantic Web can support for aiding neuroscience researchers. We then report on several projects by members of the HCLSIG, in the process illustrating the range of Semantic Web technologies that have applications in areas of biomedicine. Conclusion Semantic Web technologies present both promise and challenges. Current tools and standards are already adequate to implement components of the bench-to-bedside vision. On the other hand, these technologies are young. Gaps in standards and implementations still exist and adoption is limited by typical problems with early technology, such as the need

    This paper provides an overview of prototyping research activities of automatically switched optical networks and transport networks (ASONs/ASTNs) in China. In recent years, China has recognized the importance and benefits of the emerging ASON/ASTN techniques. During the period of 2001 and 2002, the national 863 Program of China started the preliminary ASON research projects with the main objectives to build preliminary ASON testbeds, develop control plane protocols and test their performance in the testbeds. During the period of 2003 and 2004, the 863 program started ASTN prototyping equipment projects for more practical applications. Totally 12 ASTN equipments are being developed by three groups led by Chinese venders: ZTE with Beijing University of Posts and Telecommunications (BUPT), Wuhan Research Institute of Posts and Telecommunication (WRI) with Shanghai Jiao Tong University (SJTU), and Huawei Inc. Meanwhile, as the ASTN is maturing, some of the China"s carries are participating in the OIF"s World Interoperability Demonstration, carrying out ASTN test, or deploying ASTN backbone networks. Finally, several ASTN backbone networks being tested or deployed now will be operated by the carries in 2005. The 863 Program will carry out an ASTN field trail in Yangtse River Delta, and finally deploy the 3TNET. 3TNET stands for Tbps transmission, Tbps switching, and Tbps routing, as well as a network integrating the above techniques. A task force under the "863" program is responsible for ASTN equipment specifications and interoperation agreements, technical coordination among all the participants, schedule of the whole project during the project undergoing, and organization of internetworking of all the equipments in the laboratories and field trials.

    2015-01-01

    Atherosclerotic cardiovascular diseases (ASCVD) are defined as a series of diseases caused by atherosclerosis (AS), including coronary heart disease (CHD), myocardial infarction (MI), stable or unstable angina pectoris, revascularization of coronary artery or other arteries, stroke, transient cerebral ischemic onset or atherosclerotic peripheral arterial disease. AS has common pathological basis with ASCVD as it is a general arterial regressive disease of human beings. With the industrialization progression, AS morbidity increases annually and it also leads to coronary atherosclerotic heart disease, cerebral stroke and peripheral artery stenosed occlusion or dilation, thus becoming the main cause for high disability and mortality. The main purpose of translational medicine is to break the intrinsic barrier between basic medicine with drug research and development as well as clinical and public healthcare, and establish a direct connection between them. It is also can rapidly transform basic research results to new clinical preventive and therapeutic methods. This study mainly reviewed AS from the aspect of translational medicine, aiming to provide a reliable basis for the prevention and treatment of AS.

  18. Advances in lactoferrin research concerning bovine mastitis.

    Shimazaki, Kei-Ichi; Kawai, Kazuhiro

    2017-02-01

    Lactoferrin is a multifunctional, iron-binding glycoprotein found in milk and other exocrine secretions. Lactoferrin in milk plays vital roles in the healthy development of newborn mammals, and is also an innate resistance factor involved in the prevention of mammary gland infection by microorganisms. Inflammation of the udder because of bacterial infection is referred to as mastitis. There have been many investigations into the relationships between lactoferrin and mastitis, which fall into several categories. The main categories are fluctuations in the lactoferrin concentration of milk, lactoferrin activity against mastitis pathogens, elucidation of the processes underlying the onset of mastitis, participation of lactoferrin in the immune system, and utilization of lactoferrin in mastitis treatment and prevention. This minireview describes lactoferrin research concerning bovine mastitis. In the 1970s, many researchers reported that the lactoferrin concentration fluctuates in milk from cows with mastitis. From the late 1980s, many studies clarified the infection-defense mechanism in the udder and the contribution of lactoferrin to the immune system. After the year 2000, the processes underlying the onset of mastitis were elucidated in vivo and in vitro, and lactoferrin was applied for the treatment and prevention of mastitis.

    This project has been performed as cooperative research between KAERI and USNRC. Human factors issues related to soft controls, which is one of key features of advanced HSI, are identified in this project. The issues are analyzed for the evaluation approaches in either experimental or analytical ways. Also, issues requiring additional researches for the evaluation of advanced HSI are identified in the areas of advanced information systems design, computer-based procedure systems, soft controls, human systems interface and plant modernization process, and maintainability of digital systems. The issues are analyzed to discriminate the urgency of researches on it to high, medium, and low levels in consideration of advanced HSI development status in Korea, and some of the issues that can be handled by experimental researches are identified. Additionally, an experimental study is performed to compare operator's performance on human error detection in advanced control rooms vs. in conventional control rooms. It is found that advanced control rooms have several design characteristics hindering operator's error detection performance compared to conventional control rooms.

    Social media have great potential for effectively communicating about public health risks so people make healthier and safer choices. If used appropriately, social media can strengthen trust between the public and the institution. If used inappropriately, it may also create distrust. This note addresses some of the ethical challenges in using social media for communication and research. It reflects on opportunities in social media risk communication based on experience from the World Health Organization (WHO) and suggests a code of engagement be included in corporate social media policies that contain guidance as to what conduct is or is not appropriate with a view to maintaining public trust in the institution. The note concludes with considerations about the ethical use of social media in research, which is particularly relevant for entities communicating about ionizing radiation, including during emergency situations.

    2016-01-01

    Parkinson's disease (PD) is the second most common neurodegenerative disease, and the numbers are projected to double in the next two decades with the increase in the aging population. An important focus of current research is to develop interventions to slow the progression of the disease. However, prerequisites to it include the development of reliable biomarkers for early diagnosis which would identify at-risk groups and disease progression. In this review, we present updated evidence of already known clinical biomarkers (such as hyposmia and rapid eye movement (REM) sleep behavior disorder (RBD)) and neuroimaging biomarkers, as well as newer possible markers in the blood, CSF, and other tissues. While several promising candidates and methods to assess these biomarkers are on the horizon, it is becoming increasingly clear that no one candidate will clearly fulfill all the roles as a single biomarker. A multimodal and combinatorial approach to develop a battery of biomarkers will likely be necessary in the future.

    My research lies at the intersection of three disciplines: hydrology, climatology, and geomorphology, and focusses on understanding the drivers of changing flood hazards to improve flood projections. Because flooding has major impacts on people's lives, and flood losses are projected to continue to increase in future decades, attribution studies are readily picked up by the press. As an Early Career Researcher, I will share my own experiences in communicating flood-related research results (through university press releases, Twitter, blog posts, and interviews), and what I have learnt about the types of strategies that can be followed to increase research dissemination/outreach, and the "Attention Score" of individual papers. In terms of interacting with the media, I will also share some suggestions regarding the types of questions that often arise, as well as awareness strategies to avoid potential pitfalls, misunderstandings or misinterpretations.

    May, Choo Yuen; Nesaretnam, Kalanithi

    2014-01-01

    Palm oil is the major oil produced, with annual world production in excess of 50 million tonnes. About 85% of global palm oil produced is used in food applications. Over the past three decades, research on nutritional benefits of palm oil have demonstrated the nutritional adequacy of palm oil and its products, and have resulted in transitions in the understanding these attributes. Numerous studies have demonstrated that palm oil was similar to unsaturated oils with regards to effects on blood lipids. Palm oil provides a healthy alternative to trans-fatty acid containing hydrogenated fats that have been demonstrated to have serious deleterious effects on health. The similar effects of palm oil on blood lipids, comparable to other vegetable oils could very well be due to the structure of the major triglycerides in palm oil, which has an unsaturated fatty acid in the stereospecific numbers (sn)-2 position of the glycerol backbone. In addition, palm oil is well endowed with a bouquet of phytonutrients beneficial to health, such as tocotrienols, carotenoids, and phytosterols. This review will provide an overview of studies that have established palm oil as a balanced and nutritious oil. PMID:25821404

    Hoffmann, Jan; Magis, Delphine

    2013-01-01

    The pathophysiological understanding of migraine and other primary headaches has been substantially improved over the last 20 years. A milestone that paved the way for successful research was the development of the International Classification of Headache Disorders published by the International Headache Society in 1988. The classification facilitated a clear clinical diagnosis of headache disorders and allowed research efforts to be focused on clearly defined syndromes. Recent advances in the understanding of headache disorders have been driven by the availability of new research tools, such as advanced imaging techniques, genetic tools, pharmaceutical compounds and devices for electrical or magnetic stimulation. The latest scientific and clinical advances were presented at the recent European Headache and Migraine Trust International Congress (EHMTIC) in London (UK).

    Little is known about how social media are used in cancer care. We conducted a systematic review of the use and taxonomy of social media in cancer-related studies, in PubMed, Web of Knowledge, CINAHL, and Google Scholar. We located 1350 articles published through October 2013; 69 met study inclusion criteria. Early research (1996-2007) was predominantly descriptive studies of online forums. Later, researchers began analyzing blogs, videos shared on YouTube, and social networking sites. Most studies (n = 62) were descriptive, and only 7 reported intervention studies published since 2010. Future research should include more intervention studies to determine how social media can influence behavior, and more empirical research is needed on how social media may be used to reduce health disparities.

    2015-04-01

    With the growth of social media use in both the private and public spheres, researchers are currently exploring the new opportunities and practices offered by these tools in the research lifecycle. This area is still in its infancy: As methodological approaches and methods are being tested - mainly through pragmatic and exploratory approaches - practices are being shaped and negotiated by the actors involved in research. A further element of complexity is added by the ambivalent status of social media within research activities. They can be both a tool - for recruitment, data collection, analysis - and data - as what constitutes the corpus to be analysed - both in an observational and interactive domain. This synthetic analysis of the literature is aimed at identifying how social media are currently being used in research and how they fit into the research lifecycle. We identify and discuss emerging evidence and trends in the adoption of social media in research, which can be used and applied by psychiatry research practitioners as a framework to inform the development of a personalized research network and social media strategy in research.

    2017-01-01

    Full Text Available Rapid changes in information and communication technologies cause serious developments in marketing field similar to every sector. In parallel with these developments, the social media channels which appear as Web 2.0 applications have a number of advantages in comparison with traditional media channels. Social media gained a place in marketing activities because of its advantages. Social media is added on instruments in line with these developments that countries benefit in marketing activities for attracting more tourists, investment and becoming prominent against the other cities. Cities intensively benefit from social media because of social media’s properties like reaching the large masses, low marketing cost, interaction, receiving feedbacks rapidly, etc. Within this context, the purpose of this research is to determine the use statuses of social media by metropolitan municipalities as part of city marketing. In accordance with this purpose, official social media accounts of 30 metropolitan municipalities are investigated between the dates of 01/09/2016 and 30/09/2016, then their shares in social media channels are investigated in the context of city marketing.It is observed that two metropolitan municipalities do not have official Facebook accounts, four metropolitan municipalities do not have an official Twitter account as well. Again, it is found that 19 metropolitan municipalities do not have an official Instagram account and 17 metropolitan municipalities do not have official YouTube account. In consequence, it is observed that, our metropolitan municipalities do not benefit from social media effectively for city marketing activities.

    2016-11-07

    Recruiting an adequate number of participants into medical research studies is challenging for many researchers. Over the past 10 years, the use of social media websites has increased in the general population. Consequently, social media websites are a new, powerful method for recruiting participants into such studies. The objective was to answer the following questions: (1) Is the use of social media more effective at research participant recruitment than traditional methods? (2) Does social media recruit a sample of research participants comparable to that recruited via other methods? (3) Is social media more cost-effective at research participant recruitment than traditional methods? Using the MEDLINE, PsycINFO, and EMBASE databases, all medical research studies that used social media and at least one other method for recruitment were identified. These studies were then categorized as either interventional studies or observational studies. For each study, the effectiveness of recruitment, demographic characteristics of the participants, and cost-effectiveness of recruitment using social media were evaluated and compared with that of the other methods used. The social media sites used in recruitment were identified, and if a study stated that the target population was "difficult to reach" as identified by the authors of the study, this was noted. Out of 30 studies, 12 found social media to be the most effective recruitment method, 15 did not, and 3 found social media to be equally effective as another recruitment method. Of the 12 studies that found social media to be the best recruitment method, 8 were observational studies while 4 were interventional studies. Of the 15 studies that did not find social media to be the best recruitment method, 7 were interventional studies while 8 were observational studies. In total, 8 studies stated that the target population was "hard-to-reach," and 6 of these studies found social media to be the most effective recruitment

  12. ASPECTS REGARDING THE USE OF SOCIAL MEDIA IN QUALITATIVE MARKETING RESEARCH

    Directory of Open Access Journals (Sweden)

    Mirela Cristina VOICU

    2015-07-01

    Full Text Available In order to carry out an efficient marketing activity, it is well known that entrepreneurs have to find out, first of all, where and how consumers spend their time, what are the communication channels and forms they prefer and then try to interact with the customers on their territory and on their own terms. The forms of communication that are gaining momentum currently, are taking place online, especially in the social media. A growing number of consumers have become open towards and familiar with social media, sharing their opinions daily through these means. Since the emergence of the social media phenomenon, its use has grown and has become widespread in a short period of time. In response to this phenomenon, social media marketing has developed at a similar pace and in a similar direction, and this is also reflected in the existing opportunities for using social media in qualitative marketing research.

    2017-10-01

    To review the current state of science using big data to advance Alzheimer's disease (AD) research and practice. In particular, we analyzed the types of research foci addressed, corresponding methods employed and study findings reported using big data in AD. Systematic review was conducted for articles published in PubMed from January 1, 2010 through December 31, 2015. Keywords with AD and big data analytics were used for literature retrieval. Articles were reviewed and included if they met the eligibility criteria. Thirty-eight articles were included in this review. They can be categorized into seven research foci: diagnosing AD or mild cognitive impairment (MCI) (n=10), predicting MCI to AD conversion (n=13), stratifying risks for AD (n=5), mining the literature for knowledge discovery (n=4), predicting AD progression (n=2), describing clinical care for persons with AD (n=3), and understanding the relationship between cognition and AD (n=3). The most commonly used datasets are AD Neuroimaging Initiative (ADNI) (n=16), electronic health records (EHR) (n=11), MEDLINE (n=3), and other research datasets (n=8). Logistic regression (n=9) and support vector machine (n=8) are the most used methods for data analysis. Big data are increasingly used to address AD-related research questions. While existing research datasets are frequently used, other datasets such as EHR data provide a unique, yet under-utilized opportunity for advancing AD research. Copyright © 2017 Elsevier B.V.

    Many institutions use social media to share research with the general public. However, the influence of social media on the dissemination of a surgical research article itself is unknown. Our objective was to determine whether a blog post highlighting the findings of a surgical research article would lead to increased dissemination of the article itself. We prospectively followed the online page views of an article that was published online in Surgery in May 2015 and published in print in August 2015. The authors subsequently released a blog post in October 2015 to promote the research. The number of article page views from the journal's website was obtained before and after the blog post, along with the page views from the blog post itself. Social media influence data were collected, including social activity in the form of mentions on social media sites, scholarly activity in online libraries, and scholarly commentary. The article's online activity peaked in the first month after online publication (475 page views). Online activity plateaued by 4 months after publication, with 118 monthly page views, and a blog post was subsequently published. The blog post was viewed by 1566 readers, and readers spent a mean of 2.5 minutes on the page. When compared to the projected trend, the page views increased by 33% in the month after the blog post. The blog post resulted in a 9% increase in the social media influence score and a 5% absolute increase in total article page views. Social media is an important tool for sharing surgical research. Our data suggest that social media can increase distribution of an article's message and also potentially increase dissemination of the article itself. We believe that authors should consider using social media to increase the dissemination of traditionally published articles. Copyright © 2016 Association of Program Directors in Surgery.

    Liu, Xiao; Chen, Hsinchun

    2015-12-01

    Social media offer insights of patients' medical problems such as drug side effects and treatment failures. Patient reports of adverse drug events from social media have great potential to improve current practice of pharmacovigilance. However, extracting patient adverse drug event reports from social media continues to be an important challenge for health informatics research. In this study, we develop a research framework with advanced natural language processing techniques for integrated and high-performance patient reported adverse drug event extraction. The framework consists of medical entity extraction for recognizing patient discussions of drug and events, adverse drug event extraction with shortest dependency path kernel based statistical learning method and semantic filtering with information from medical knowledge bases, and report source classification to tease out noise. To evaluate the proposed framework, a series of experiments were conducted on a test bed encompassing about postings from major diabetes and heart disease forums in the United States. The results reveal that each component of the framework significantly contributes to its overall effectiveness. Our framework significantly outperforms prior work.

  17. Social proof in social media shopping: An experimental design research

    Abdul Talib Yurita Yakimin

    2017-01-01

    Full Text Available The practices of social proof techniques to attract consumers to shop on social media have proliferated over time and been used extensively. The reviewed literature uncovers that social community recommendation, customers’ ratings and reviews, celebrity’s endorser and numbers of likes, affect consumers’ purchasing decisions. However, the effect of different types of social proof techniques on purchasing intention is unknown. This study empirically compares the effect of number of followers, celebrity endorser and social community recommendation on consumers’ purchasing intention. An experiment has been conducted and the results reveal that the consumers’ purchasing intention differs between groups. Further analysis discovers that the impact on consumers’ purchasing intention is different between high number of followers and low number of followers, and between having social community recommendation and not having social community recommendation. Though, the impact of these two techniques is equal wherein no technique is superior to other. In order to gain purchasing engagement and boost online sales, online businesses on social media are encouraged to use the power of social proof technique, either by increasing the number of followers or providing more social community recommendations.

  18. Ethical issues in using social media for health and health care research.

    Science.gov (United States)

    McKee, Rebecca

    2013-05-01

    The dramatic growth of social media in recent years has not gone unnoticed in the health sector. Media such as Facebook and Twitter are increasingly being used to disseminate information among health professionals and patients but, more recently, are being seen as a source of data for surveillance and research, for example by tracking public concerns or capturing discourses taking place outside traditional media outlets. This raises ethical issues, in particular the extent to which postings are considered public or private and the right to anonymity of those posting on social media. These issues are not clear cut as social media, by their nature, blur the boundary between public and private. There is a need for further research on the beliefs and expectations of those using social media in relation to how their material might be used in research. In contrast, there are areas where the ethical issues are more clear cut, such as when individuals are active participants in research, where traditional considerations apply.

Despite this, to date there has been no specific regulatory guidance and there has been little in the bioethics literature to guide investigators and institutional review boards (IRBs) faced with navigating the ethical issues such use raises. We begin to fill this gap by first defending a nonexceptionalist methodology for assessing social media recruitment; second, examining respect for privacy and investigator transparency as key norms governing social media recruitment; and, finally, analyzing three relatively novel aspects of social media recruitment: (i) the ethical significance of compliance with website "terms of use"; (ii) the ethics of recruiting from the online networks of research participants; and (iii) the ethical implications of online communication from and between participants. Two checklists aimed at guiding investigators and IRBs through the ethical issues are included as appendices.

    2013-02-07

    Hydrogen fuel cells, the most common type of which are proton exchange membrane fuel cells (PEMFCs), are on a rapid path to commercialization. We credit physical chemistry research in oxygen reduction electrocatalysis and theory with significant breakthroughs, enabling more cost-effective fuel cells. However, most of the physical chemistry has been restricted to studies of platinum and related alloys. More work is needed to better understand electrocatalysts generally in terms of properties and characterization. While the advent of such highly active catalysts will enable smaller, less expensive, and more powerful stacks, they will require better understanding and a complete restructuring of the diffusion media in PEMFCs to facilitate faster transport of the reactants (O2) and products (H2O). Even Ohmic losses between materials become more important at high power. Such lessons from PEMFC research are relevant to other electrochemical conversion systems, including Li-air batteries and flow batteries.

    Full Text Available Metastatic and recurrent tumors have been identified as the leading attribute to the lung cancer deaths. Cancer research has demonstrated the critical role circulating tumor cells (CTCs play in the metastatic spread of carcinomas and the recurrence of lung cancer. The rapid advancement of technology in targeted therapy resolves the embarrassing situation for those late-stage patients whose tumor tissues cannot be obtained. CTCs, as a substitute for the tumor tissues, represent a decisive tool to the cancer treatment strategy. Thus, CTCs exert a fundamental role in the early detection of micro-metastasis, assisting in diagnosis, prognosis and monitoring of the recurrent tumors, and subsequently choosing an individualized approach for the therapeutic treatment. This article will review the advances, which have been made in the research area of CTCs with the aid of its applications in cancer therapy.

    Since a new advanced therapy medicinal product is discovered until finally allowed its sale in the domestic market, it has to overcome a series of stages. Biomedical research is the first phase, currently its situation is encouraging to the increase in the number of clinical trials in Spain and in the rest of the world, despite the economic situation and the various difficulties that have faced the pharmaceutical laboratories. The next phase consists in obtaining the authorization of marketing of the European Medicines Agency. After authorization, will attempt to set a fair and moderate price for inclusion in the list of health provision of Social Security. A price for a drug that provides added value to health and society, a price that is generated profits for the pharmaceutical companies that hope to make up for the years of work and investment. Commitment to advanced therapy must be clear and forceful, to fund ongoing research projects and encouraging their creation with economic aid.

    The U.S. Department of Energy Office of River Protection (ORP) has implemented an integrated program to increase the loading of Hanford tank wastes in glass while meeting melter lifetime expectancies and process, regulatory, and product quality requirements. The integrated ORP program is focused on providing a technical, science-based foundation from which key decisions can be made regarding the successful operation of the Hanford Tank Waste Treatment and Immobilization Plant (WTP) facilities. The fundamental data stemming from this program will support development of advanced glass formulations, key process control models, and tactical processing strategies to ensure safe and successful operations for both the low-activity waste (LAW) and high-level waste (HLW) vitrification facilities with an appreciation toward reducing overall mission life. The purpose of this advanced HLW glass research and development plan is to identify the near-, mid-, and longer-term research and development activities required to develop and validate advanced HLW glasses and their associated models to support facility operations at WTP, including both direct feed and full pretreatment flowsheets. This plan also integrates technical support of facility operations and waste qualification activities to show the interdependence of these activities with the advanced waste glass (AWG) program to support the full WTP mission. Figure ES-1 shows these key ORP programmatic activities and their interfaces with both WTP facility operations and qualification needs. The plan is a living document that will be updated to reflect key advancements and mission strategy changes. The research outlined here is motivated by the potential for substantial economic benefits (e.g., significant increases in waste throughput and reductions in glass volumes) that will be realized when advancements in glass formulation continue and models supporting facility operations are implemented.

    The past three decades have witnessed a surge in research on spirituality and health. This growing body of literature has linked many aspects of spirituality as well as religion to both positive and negative indices of human functioning. However, studies have primarily been descriptive, focusing on identifying associations between spirituality and health, rather than explanatory, focusing on identifying mechanisms underlying observed relationships. Earlier research is also limited by failure to control for salient covariates, apply prospective design, and use sophisticated measurements with well defined and empirically-validated factors. Recent research, however, is advancing the study of spirituality and health by examining not only whether religious factors are relevant to human health, but also how spirituality may functionally impact medical and psychological wellbeing and illness. This article introduces a special issue on Spirituality and Health containing 12 full-length research reports to further this welcomed, emerging trend.

    We have developed a new introductory physics/chemistry programme that teaches advanced science topics and practical laboratory skills to freshmen undergraduate students through the use of student-led, bona fide research activities. While many recent attempts to improve college-level physics education have focused on integrating interactive demonstrations and activities into traditional passive lectures, we have taken the idea of active-learning several steps further. Working in conjunction with several research faculty at Binghamton University, we have created a programme that puts undergraduate students on an accelerated path towards working in real research laboratories performing publishable research. Herein, we describe in detail the programme goals, structure, and educational content, and report on our promising initial student outcomes.

    The Advanced Test Reactor National Scientific User Facility (ATR NSUF), based at the Idaho National Laboratory in the United States, is supporting Department of Energy and industry research efforts to ensure the properties of materials in light water reactors are well understood. The ATR NSUF is providing this support through three main efforts: establishing unique infrastructure necessary to conduct research on highly radioactive materials, conducting research in conjunction with industry partners on life extension relevant topics, and providing training courses to encourage more U.S. researchers to understand and address LWR materials issues. In 2010 and 2011, several advanced instruments with capability focused on resolving nuclear material performance issues through analysis on the micro (10-6 m) to atomic (10-10 m) scales were installed primarily at the Center for Advanced Energy Studies (CAES) in Idaho Falls, Idaho. These instruments included a local electrode atom probe (LEAP), a field-emission gun scanning transmission electron microscope (FEG-STEM), a focused ion beam (FIB) system, a Raman spectrometer, and an nanoindentor/atomic force microscope. Ongoing capability enhancements intended to support industry efforts include completion of two shielded, irradiation assisted stress corrosion cracking (IASCC) test loops, the first of which will come online in early calendar year 2013, a pressurized and controlled chemistry water loop for the ATR center flux trap, and a dedicated facility intended to house post irradiation examination equipment. In addition to capability enhancements at the main site in Idaho, the ATR NSUF also welcomed two new partner facilities in 2011 and two new partner facilities in 2012; the Oak Ridge National Laboratory, High Flux Isotope Reactor (HFIR) and associated hot cells and the University California Berkeley capabilities in irradiated materials analysis were added in 2011.

    2015-07-01

    Craniofacial anomalies are among the most common human birth defects and have considerable functional, aesthetic, and social consequences. The early developmental origin as well as the anatomical complexity of the head and face render these tissues prone to genetic and environmental insult. The establishment of craniofacial clinics offering comprehensive care for craniofacial patients at a single site together with international research networks focused on the origins and treatment of craniofacial disorders has led to tremendous advances in our understanding of the etiology and pathogenesis of congenital craniofacial anomalies. However, the genetic, environmental, and developmental sources of many craniofacial disorders remain unknown. To overcome this problem and further advance craniofacial research, we must recognize current challenges in the field and establish priority areas for study. We still need (i) a deeper understanding of variation during normal development and within the context of any disorder, (ii) improved genotyping and phenotyping and understanding of the impact of epigenetics, (iii) continued development of animal models and functional analyses of genes and variants, and (iv) integration of patient derived cells and tissues together with 3D printing and quantitative assessment of surgical outcomes for improved practice. Only with fundamental advances in each of these areas will we be able to meet the challenge of translating potential therapeutic and preventative approaches into clinical solutions and reduce the financial and emotional burden of craniofacial anomalies.

    When sampling part of the enormous amounts of social media data it is important to consider whether the sample is representative. Any method of studying the sampled data is also prone to bias. Sampling and bias aside the data may be generated with malicious intent, such as deception. Deception is a complicated (broad, situational, vague) concept. It seems improbable that an automated computer system would be able to find deception as such. Instead, we argue that the role of a system would be to aid the human analyst by detecting indicators, or clues, of (potential) deception. Indicators could take many forms and are typically neither necessary nor sufficient for there to be an actual deception. However, by using one or combining several of them a human may reach conclusions. Indicators are not necessarily dependent and will be added to or removed from the analysis depending on the circumstances. This modularity can help in counteracting/alleviating attacks on the system by an adversary. If we become aware that an indicator is compromised we can remove it from the analysis and/or replace it with a more sophisticated method that give us a similar indication.

    Experimental research has become complex and thus a challenge to science education. Only very few students can typically be trained on advanced scientific equipment. It is therefore important to find new tools that allow all students to acquire laboratory skills individually and independent of where they are located. In a design-based research process we have investigated the feasibility of using a virtual laboratory as a photo-realistic and scientifically valid representation of advanced scientific infrastructure to teach modern experimental science, here, molecular quantum optics. We found a concept based on three educational principles that allows undergraduate students to become acquainted with procedures and concepts of a modern research field. We find a significant increase in student understanding using our Simulated Interactive Research Experiment (SiReX), by evaluating the learning outcomes with semi-structured interviews in a pre/post design. This suggests that this concept of an educational tool can be generalized to disseminate findings in other fields.

    2015-12-01

    Our ability to advance scientific research in order to better understand complex Earth systems, address emerging geoscience problems, and meet societal challenges is increasingly dependent upon the concept of Open Science and Data. Although these terms are relatively new to the world of research, Open Science and Data in this context may be described as transparency in the scientific process. This includes the discoverability, public accessibility and reusability of scientific data, as well as accessibility and transparency of scientific communication (www.openscience.org). Scientists and the US government alike are realizing the critical need for easy discovery and access to multidisciplinary data to advance research in the geosciences. The NSF-supported EarthCube project was created to meet this need. EarthCube is developing a community-driven common cyberinfrastructure for the purpose of accessing, integrating, analyzing, sharing and visualizing all forms of data and related resources through advanced technological and computational capabilities. Engaging the geoscience community in EarthCube's development is crucial to its success, and EarthCube is providing several opportunities for geoscience involvement. This presentation will provide an overview of the activities EarthCube is employing to entrain the community in the development process, from governance development and strategic planning, to technical needs gathering. Particular focus will be given to the collection of science-driven use cases as a means of capturing scientific and technical requirements. Such activities inform the development of key technical and computational components that collectively will form a cyberinfrastructure to meet the research needs of the geoscience community.

    To review the research advances in animal models of human disc degeneration. The relative articles in recent years were extensively reviewed. Studies both at home and abroad were analyzed and classified. The advantages and disadvantages of each method were compared. Studies were classified as either experimentally induced models or spontaneous models. The induced models were subdivided as mechanical (alteration of forces on the normal disc), structural (injury or chemical alteration) and genetically induced models. Spontaneous models included those animals that naturally developed degenerative disc disease. Animal model of intervertebral disc degeneration is an important path for revealing the pathogenesis of human disc degeneration, and play an important role in testing novel interventions. With recent advances in the relevance of animal models and humans, it has a great prospect in study of human disc degeneration.

    Research was initiated in advanced plasma thrusters that capitalizes on lab capabilities in plasma science and technology. The goal of the program was to examine the scaling issues of magnetoplasmadynamic (MPD) thruster performance in support of NASA's MPD thruster development program. The objective was to address multi-megawatt, large scale, quasi-steady state MPD thruster performance. Results to date include a new quasi-steady state operating regime which was obtained at space exploration initiative relevant power levels, that enables direct coaxial gun-MPD comparisons of thruster physics and performance. The radiative losses are neglible. Operation with an applied axial magnetic field shows the same operational stability and exhaust plume uniformity benefits seen in MPD thrusters. Observed gun impedance is in close agreement with the magnetic Bernoulli model predictions. Spatial and temporal measurements of magnetic field, electric field, plasma density, electron temperature, and ion/neutral energy distribution are underway. Model applications to advanced mission logistics are also underway.

    2015-01-01

    In recent years, nonalcoholic fatty liver disease (NAFLD) has increased because of the growing prevalence of obesity and overweight in the pediatric population. It has become the most common form of chronic liver diseases in children and the related research on NAFLD is expanded. The "two-hit" and "multiple hit" hypothesis have been widely accepted, and some research has shown that genetic, diet structure and environmental factors appear to play a crucial role in the development of pediatric NAFLD. Though it is expected by researchers, there is not an available satisfactory noninvasive marker for the diagnosis of this disease. Fortunately, some new non-invasive prediction scores for pediatric NAFLD have been developed. There is currently no established special therapy, and lifestyle intervention should be adequate for most cases of NAFLD in children. This article reviews the advances in the current knowledge and ideas concerning pediatric NAFLD, and discusses the diagnosis, perspective therapies and scoring methods for this disease.

    2012-12-12

    An appropriate balance between teaching, scholarship, and service is important for a faculty member to have a satisfying and successful career. The relative emphasis on each area normally changes during the course of a career. Although some level of scholarly output is an ongoing and fundamental expectation of all faculty members, this activity is too often given low priority, particularly among faculty members in practice areas who may have a minimal background in research and large demands on their time for teaching and clinical service. Addressing this issue requires establishing a shared commitment between administrators and faculty members, as well as identifying or developing education programs that will ensure research competence for practice faculty members. This paper provides insights into the role that scholarship and research should have for all pharmacy faculty members and provides suggestions for how to better advance this critical component within academic pharmacy.

    2000-04-01

    Wolsong Unit 1 as the first heavy water reactor in Korea has been in service for 17 years since 1983. It would be about the time to prepare a plan for the solution of problems due to aging of the reactor. The aging of CANDU reactor could lead especially to the steam generator cruding and pressure tube sagging and creep and then decreases the operation margin to make some problems on reactor operations and safety. The counterplan could be made in two ways. One is to repair or modify reactor itself. The other is to develop new advanced fuel to increase of CANDU operation margin effectively, so as to compensate the reduced operation margin. Therefore, the first objectives in the present R and D is to develop the CANFLEX-NU (CANDU Flexible fuelling-Natural Uranium) fuel as a CANDU advanced fuel. The second objectives is to develop CANDU advanced fuel bundle to utilize advanced fuel cycles such as recovered uranium, slightly enriched uranium, etc. and so to raise adaptability for change in situation of uranium market. Also, it is to develop CANDU advanced fuel technology which improve uranium utilization to cope with a world-wide imbalance between uranium supply and demand, without significant modification of nuclear reactor design and refuelling strategies. As the implementations to achieve the above R and D goal, the work contents and scope of technology development of CANDU advanced fuel using natural uranium (CANFLEX-NU) are the fuel element/bundle designs, the nuclear design and fuel management analysis, the thermalhydraulic analysis, the safety analysis, fuel fabrication technologies, the out-pile thermalhydraulic test and in-pile irradiation tests performed. At the next, the work scopes and contents of feasibility study of CANDU advanced fuel using recycled uranium (CANFLEX-RU) are the fuel element/bundle designs, the reactor physics analysis, the thermalhydraulic analysis, the basic safety analysis of a CANDU-6 reactor with CANFLEX-RU fuel, the fabrication and

  7. Assessment of Research Needs for Advanced Fuel Cells

    Energy Technology Data Exchange (ETDEWEB)

    Penner, S.S.

    1985-11-01

    The DOE Advanced Fuel Cell Working Group (AFCWG) was formed and asked to perform a scientific evaluation of the current status of fuel cells, with emphasis on identification of long-range research that may have a significant impact on the practical utilization of fuel cells in a variety of applications. The AFCWG held six meetings at locations throughout the country where fuel cell research and development are in progress, for presentations by experts on the status of fuel cell research and development efforts, as well as for inputs on research needs. Subsequent discussions by the AFCWG have resulted in the identification of priority research areas that should be explored over the long term in order to advance the design and performance of fuel cells of all types. Surveys describing the salient features of individual fuel cell types are presented in Chapters 2 to 6 and include elaborations of long-term research needs relating to the expeditious introduction of improved fuel cells. The Introduction and the Summary (Chapter 1) were prepared by AFCWG. They were repeatedly revised in response to comments and criticism. The present version represents the closest approach to a consensus that we were able to reach, which should not be interpreted to mean that each member of AFCWG endorses every statement and every unexpressed deletion. The Introduction and Summary always represent a majority view and, occasionally, a unanimous judgment. Chapters 2 to 6 provide background information and carry the names of identified authors. The identified authors of Chapters 2 to 6, rather than AFCWG as a whole, bear full responsibility for the scientific and technical contents of these chapters.

    2012-09-01

    Full Text Available This paper presents a survey on recent advances in honeypot research from a review of 80+ papers on honeypots and related topics mostly published after year 2005. This paper summarizes 60 papers that had significant contribution to the field. In reviewing the literature, it became apparent that the research can be broken down into five major areas:  new types of honeypots to cope with emergent new security threats,  utilizing honeypot output data to improve the accuracy in threat detections,  configuring honeypots to reduce the cost of maintaining honeypots as well as to improve the accuracy in threat detections,  counteracting honeypot detections by attackers, and  legal and ethical issues in using honeypots. Our literature reviews indicate that the advances in the first four areas reflect the recent changes in our networking environments, such as those in user demography and the ways those diverse users use new applications. Our literature reviews on legal and ethical issues in using honeypots reveals that there has not been widely accepted agreement on the legal and ethical issues about honeypots, which must be an important agenda in future honeypot research.

    During the past century, environmental hazards have become a major concern, not only to public health professionals, but also to the society at large because of their tremendous health, socio-cultural and economic impacts. Various anthropogenic or natural factors have been implicated in the alteration of ecosystem integrity, as well as in the development of a wide variety of acute and/or chronic diseases in humans. It has also been demonstrated that many environmental agents, acting either independently or in combination with other toxins, may induce a wide range of adverse health outcomes. Understanding the role played by the environment in the etiology of human diseases is critical to designing cost-effective control/prevention measures. This special issue of International Journal of Environmental Research and Public Health includes the proceedings of the Twelfth International Symposium on Recent Advances in Environmental Health Research. The Symposium provided an excellent opportunity to discuss the scientific advances in biomedical, environmental, and public health research that addresses global environmental health issues.

    Establishing and promoting connections between health researchers and health professional clinicians may help translate research evidence to clinical practice. Social media may have the capacity to enhance these connections. The aim of this study was to explore health researchers' and clinicians' current use of social media and their beliefs and attitudes towards the use of social media for communicating research evidence. This study used a mixed-methods approach to obtain qualitative and quantitative data. Participation was open to health researchers and clinicians. Data regarding demographic details, current use of social media, and beliefs and attitudes towards the use of social media for professional purposes were obtained through an anonymous Web-based survey. The survey was distributed via email to research centers, educational and clinical institutions, and health professional associations in Australia, India, and Malaysia. Consenting participants were stratified by country and role and selected at random for semistructured telephone interviews to explore themes arising from the survey. A total of 856 participants completed the questionnaire with 125 participants declining to participate, resulting in a response rate of 87.3%. 69 interviews were conducted with participants from Australia, India, and Malaysia. Social media was used for recreation by 89.2% (749/840) of participants and for professional purposes by 80.0% (682/852) of participants. Significant associations were found between frequency of professional social media use and age, gender, country of residence, and graduate status. Over a quarter (26.9%, 229/852) of participants used social media for obtaining research evidence, and 15.0% (128/852) of participants used social media for disseminating research evidence. Most participants (95.9%, 810/845) felt there was a role for social media in disseminating or obtaining research evidence. Over half of the participants (449/842, 53.3%) felt they had a

    Recruiting adolescent participants for research is challenging. The purpose of this study was to compare traditional in-person recruitment methods to social media recruitment. We recruited adolescents aged 14-18 years for a pilot physical activity intervention study, including a wearable physical activity tracking device and a Facebook group. Participants were recruited (a) in person from a local high school and an adolescent medicine clinic and (b) through social media, including Facebook targeted ads, sponsored tweets on Twitter, and a blog post. Data collected included total exposure (i.e., reach), engagement (i.e., interaction), and effectiveness. Effectiveness included screening and enrollment for each recruitment method, as well as time and resources spent on each recruitment method. In-person recruitment reached a total of 297 potential participants of which 37 enrolled in the study. Social media recruitment reached a total of 34,272 potential participants of which 8 enrolled in the study. Social media recruitment methods utilized an average of 1.6 hours of staff time and cost an average of $40.99 per participant enrolled, while in-person recruitment methods utilized an average of 0.75 hours of staff time and cost an average of $19.09 per participant enrolled. Social media recruitment reached more potential participants, but the cost per participant enrolled was higher compared to traditional methods. Studies need to consider benefits and downsides of traditional and social media recruitment methods based on study goals and population.

  2. Advanced testing method to evaluate the performance of respirator filter media.

    2016-10-02

    Filter media for respirator applications are typically exposed to the cyclic flow condition, which is different from the constant flow condition adopted in filter testing standards. To understand the real performance of respirator filter media in the field it is required to investigate the penetration of particles through respirator filters under cyclic flow conditions representing breathing flow patterns of human beings. This article reports a new testing method for studying the individual effect of breathing frequency (BF) and peak inhalation flow rate (PIFR) on the particle penetration through respirator filter media. The new method includes the use of DMA (Differential Mobility Analyzer)-classified particles having the most penetrating particle size, MPPS (at the constant flowrate of equivalent mean inhalation flow rate, MIFR) as test aerosol. Two condensation particle counters (CPCs) are applied to measure the particle concentrations at the upstream and downstream of test filter media at the same time. Given the 10 Hz sampling time of CPCs, close-to-instantaneous particle penetration could be measured. A pilot study was performed to demonstrate the new testing method. It is found that the effect of BF on the particle penetration of test respirator filter media is of importance at all the tested peak inhalation flow rates (PIFRs), which is different from those reported in the previous work.

    Background Establishing and promoting connections between health researchers and health professional clinicians may help translate research evidence to clinical practice. Social media may have the capacity to enhance these connections. Objective The aim of this study was to explore health researchers’ and clinicians’ current use of social media and their beliefs and attitudes towards the use of social media for communicating research evidence. Methods This study used a mixed-methods approach to obtain qualitative and quantitative data. Participation was open to health researchers and clinicians. Data regarding demographic details, current use of social media, and beliefs and attitudes towards the use of social media for professional purposes were obtained through an anonymous Web-based survey. The survey was distributed via email to research centers, educational and clinical institutions, and health professional associations in Australia, India, and Malaysia. Consenting participants were stratified by country and role and selected at random for semistructured telephone interviews to explore themes arising from the survey. Results A total of 856 participants completed the questionnaire with 125 participants declining to participate, resulting in a response rate of 87.3%. 69 interviews were conducted with participants from Australia, India, and Malaysia. Social media was used for recreation by 89.2% (749/840) of participants and for professional purposes by 80.0% (682/852) of participants. Significant associations were found between frequency of professional social media use and age, gender, country of residence, and graduate status. Over a quarter (26.9%, 229/852) of participants used social media for obtaining research evidence, and 15.0% (128/852) of participants used social media for disseminating research evidence. Most participants (95.9%, 810/845) felt there was a role for social media in disseminating or obtaining research evidence. Over half of the

    1986-01-01

    Ever since the oil crisis of 1973, researchers in various fields of chemistry have proposed various schemes to conserve energy, as well to convert the sun's abundant and limitless supply of energy to produce chemical fuels (e. g. , hydrogen from water, . •. ). The enthusiasm had no previous parallel in the mid-1970's. Unfortunately, despite the several good proposals, the results have proven - in retrospect - somewhat disappointing from an economic viable point of view. The reasons for the meagre results are manyfold not the least of which are the experimental difficulties encountered in storage systems. Moreover, the lack of a concerted, well orchestrated interdisciplinary approach has been significant. By contrast, the chemical advances made in the understanding of the processes involved in such schemes have been phenomenal. A recent book on this issue ( M. Gratzel, Energy Resources through Photochemistry and Catalysis, 1983) is witness to the various efforts and approaches taken by researchers. In the re...

    Elevated heart rate is a major risk factor for cardiovascular diseases. The inhibitor of funny current (Ⅰ (f)), a hyperpolarization-activated cyclic nucleotide-gated channel current, ivabradine is a new agent selectively reduc-ing heart rate devoid of other cardiovascular effects, which has come into the market in Europe for more than 3 years. It has been approved that pure heart rate reduction by ivabradine can improve myocardial ischemia, endothelial function and myocardial contractile function. Long-term administration will not increase all-cause mortality. Its therapeutic value in stable coronary artery disease has been verified in clinical practice, while in other fields of cardiovascular diseases still needs more evidence-based medical research. This article is a review about its recent research advances in experi-mental and clinical studies.

    2015-01-01

    Over the last two decades, various themes inherent in the responsible conduct of research (RCR) in chemistry have been brought to light through prominent cases of research misconduct. This article will describe a few of these cases especially through the lens of social media such as blogs and Twitter. A case will be made that these wholly novel modalities of online discussion are now complementing, and in some cases even circumventing some of the limitations of traditional peer review in chemistry. We present in detail our evaluation of three recent cases of RCR along with several other social media illustrations. These cases have been selected to be representative and showcase several of the most prominent issues at the intersection of traditional and social-media based peer review. In each case, basic details are presented along with a brief discussion of the underlying issues-readers interested in deeper analysis of each subject are referred to a collection of relevant articles and websites. This perspective focuses on the most important RCR issues that have arisen in the past decade, a time which we believe coincides with the serious participation of the scientific community in general, and the chemistry community in particular, in social media-based, citizen-enabled peer-review. A discussion of important trends in RCR in the age of social media, outstanding developments in this area, and questions of enduring interest for the near future concludes the article.

    1999-01-01

    This article provides a variety of alternative theoretical issues and new research directions for smoking media campaign research. The first two generations of smoking media campaign research are reviewed and new ideas about public resistance and resolving complex issues are explored. The authors critique the limits of current campaign theory and their premise that how the public resolves issues such as smoking cessation needs to be seen in a broader context. The consciousness raising, working through, and resolution stages each present a series of different research challenges and issues for investigators. These are: (1) an assessment of the perceived credibility by the target audience toward mass media, news media, health care providers, tobacco firms, area health care agencies, the health care delivery system, and different classes of providers, (2) how smokers and nonsmokers differ on the linkage among biomedical, epidemiological, and toxicological controversies, (3) how smoking issues are managed within arenas, (4) how arenas potentially undermine popular participation in public policy formation, and (5) how in the creation of dialogue there should be dual emphases on the viability of the concept and tactics.

  17. Unwarranted optimism in media portrayals of genetic research on addiction overshadows critical ethical and social concerns.

    Science.gov (United States)

    Ostergren, Jenny E; Dingel, Molly J; McCormick, Jennifer B; Koenig, Barbara A

    2015-01-01

    The cost of addiction in the United States, in combination with a host of new tools and techniques, has fueled an explosion of genetic research on addiction. Because the media has the capacity to reflect and influence public perception, there is a need to examine how treatments and preventive approaches projected to emerge from addiction genetic research are presented to the public. The authors conducted a textual analysis of 145 news articles reporting on genetic research on addiction from popular print media in the United States and from popular news and medical internet sites. In articles that report on prevention, the media emphasize vaccine development and identifying individuals at genetic risk through population screening. Articles that emphasize treatment often promote current pharmaceutical solutions and highlight the possibility of tailoring treatments to specific genetic variants. The authors raise concerns about the tendency of this coverage to focus on the benefits of pharmaceutical treatments and genetic-based approaches to prevention while neglecting or downplaying potential risks and ethical issues. This analysis suggests a need for more balanced, evidence-based media reporting on the potential outcomes of genetic research.

    2008-01-01

    Dating violence is highly prevalent among adolescents. Of importance, dating violence has been associated with negative physical and mental health outcomes for teens and high-risk behaviors such as unsafe sex practices. Although a growing body of research has examined the extent and nature of this problem, little research has considered aspects of the media that might be associated with risk for teen dating violence, such as time spent using media and effects of media content. This article provides an overview of the prevalence of teen dating violence, describes the potential for assessing media use as a risk factor, offers a conceptual model, and suggests ideas for future research.

  6. Methodological and ethical issues in research using social media: a metamethod of Human Papillomavirus vaccine studies.

    Gustafson, Diana L; Woodworth, Claire F

    2014-12-02

    Online content is a primary source of healthcare information for internet-using adults and a rich resource for health researchers. This paper explores the methodological and ethical issues of engaging in health research using social media. A metamethod was performed on systematically selected studies that used social media as a data source for exploring public awareness and beliefs about Human Papillomaviruses (HPV) and HPV vaccination. Seven electronic databases were searched using a variety of search terms identified for each of three concepts: social media, HPV vaccine, and research method. Abstracts were assessed for eligibility of inclusion; six studies met the eligibility criteria and were subjected to content analysis. A 10-item coding scheme was developed to assess the clarity, congruence and transparency of research design, epistemological and methodological underpinnings and ethical considerations. The designs of the six selected studies were sound, although most studies could have been more transparent about how they built in rigor to ensure the trustworthiness and credibility of findings. Statistical analysis that intended to measure trends and patterns did so without the benefit of randomized sampling and other design elements for ensuring generalizability or reproducibility of findings beyond the specified virtual community. Most researchers did not sufficiently engage virtual users in the research process or consider the risk of privacy incursion. Most studies did not seek ethical approval from an institutional research board or permission from host websites or web service providers. The metamethod exposed missed opportunities for using the dialogical character of social media as well as a lack of attention to the unique ethical issues inherent in operating in a virtual community where social boundaries and issues of public and private are ambiguous. This suggests the need for more self-conscious and ethical research practices when using social media

    2004-07-01

    There is currently a large research and development effort within the high-performance computing community on advanced parallel programming models. This research can potentially have an impact on parallel applications, system software, and computing architectures in the next several years. Given Sandia's expertise and unique perspective in these areas, particularly on very large-scale systems, there are many areas in which Sandia can contribute to this effort. This technical report provides a survey of past and present parallel programming model research projects and provides a detailed description of the Partitioned Global Address Space (PGAS) programming model. The PGAS model may offer several improvements over the traditional distributed memory message passing model, which is the dominant model currently being used at Sandia. This technical report discusses these potential benefits and outlines specific areas where Sandia's expertise could contribute to current research activities. In particular, we describe several projects in the areas of high-performance networking, operating systems and parallel runtime systems, compilers, application development, and performance evaluation.

    Hoang, Jenny K; McCall, Jonathan; Dixon, Andrew F; Fitzgerald, Ryan T; Gaillard, Frank

    2015-07-01

    The aim of this study was to compare the volume of individuals who viewed online versions of research articles in 2 peer-reviewed radiology journals and a radiology blog promoted by social media. The authors performed a retrospective study comparing online analytic logs of research articles in the American Journal of Neuroradiology (AJNR) and the American Journal of Roentgenology (AJR) and a blog posting on Radiopaedia.org from April 2013 to September 2014. All 3 articles addressed the topic of reporting incidental thyroid nodules detected on CT and MRI. The total page views for the research articles and the blog article were compared, and trends in page views were observed. Factors potentially affecting trends were an AJNR podcast and promotion of the blog article on the social media platforms Facebook, Tumblr, and Twitter to followers of Radiopaedia.org in February 2014 and August 2014. The total numbers of page views during the study period were 2,421 for the AJNR article and 3,064 for the AJR article. The Radiopaedia.org blog received 32,675 page views, which was 13.6 and 10.7 times greater than AJNR and AJR page views, respectively, and 6.0 times greater than both journal articles combined. Months with activity above average for the blog and the AJNR article coincided with promotion by Radiopaedia.org on social media. Dissemination of scientific material on a radiology blog promoted on social media can substantially augment the reach of more traditional publication venues. Although peer-reviewed publication remains the most widely accepted measure of academic productivity, researchers in radiology should not ignore opportunities for increasing the impact of research findings via social media.

  13. The benefits of basic research: advances in reproductive physiology.

    Science.gov (United States)

    1995-06-01

    At the Population Council's Center for Biomedical Research basic research is being conducted on the reproductive system with a view to develop new contraceptive and reproductive health technologies. Research in the Reproductive Physiology Program at the Center is carried out by reproductive endocrinologists, molecular biologists, and biochemists working in eight laboratories. In several of the laboratories the function of hormones that regulate spermatogenesis is studied. Scientists in Milan Bagchi's laboratory have developed a model system, composed of cellular components in a test tube, that allows them to study the full sequence of events involved in signal transduction. In James Catterall's laboratory, scientists study how androgens regulate sexual development at the molecular level. The steroid hormones cortisol and corticosterone play critical roles in mammalian fetal development. Scientists in several laboratories study the function of two specialized testicular cells: the Leydig and Sertoli cells. The Leydig cell synthesizes and secretes testosterone, an androgen that regulates spermatogenesis. The Sertoli cell maintains the environment in which spermatogenesis occurs. Researchers in Glen Gunsalus's laboratory study an androgen-binding protein secreted by the Sertoli cell. In collaboration with scientists at the Shanghai Research Center of Biotechnology, they used advanced genetic techniques to create a biologically active form of the protein in silk worm larvae. Scientists in Patricia Morris's laboratory recently identified molecular signals that control the interactions between developing sperm and Sertoli and Leydig cells. In the laboratory of David Phillips, scientists are investigating how the HIV virus penetrates the outer layer of cells in the genital tract and infects underlying cells. In 1994 a vaginally applied microbicide was developed that may inhibit infection by sexually transmitted diseases including HIV. Applications of basic research such

    There is increasing interest in leveraging social media to prevent childhood obesity, however, the evidence base for how social media currently influences related behaviors and how interventions could be developed for these platforms is lacking. This commentary calls for research on the extent to which mothers use social media to learn about child feeding practices and the mechanisms through which social media influences their child feeding practices. Such formative research could be applied to the development and dissemination of evidence-based childhood obesity prevention programs that utilize social media. Mothers are identified as a uniquely important target audience for social media-based interventions because of their proximal influence on children's eating behavior and their high engagement with social media platforms. Understanding mothers' current behaviors, interests, and needs as they relate to their social media use and child feeding practices is an integral first step in the development of interventions that aim to engage mothers for obesity prevention. This commentary highlights the importance of mothers for childhood obesity prevention; discusses theoretical and analytic frameworks that can inform research on social media and mothers' child feeding practices; provides evidence that social media is an emerging context for social influences on mothers' attitudes and behaviors in which food is a salient topic; and suggests directions for future research.

  15. Developing a research agenda on ethical issues related to using social media in healthcare.

    Adams, Samantha A; Van Veghel, Dennis; Dekker, Lukas

    2015-07-01

    The consequences of using publicly available social media applications specifically for healthcare purposes are largely unaddressed in current research. Where they are addressed, the focus is primarily on issues of privacy and data protection. We therefore use a case study of the first live Twitter heart operation in the Netherlands, in combination with recent literature on social media from other academic fields, to identify a wide range of ethical issues related to using social media for health-related purposes. Although this case reflects an innovative approach to public education and patient centeredness, it also illustrates the need for institutions to weigh the various aspects of use and to develop a plan to deal with these on a per case basis. Given the continual development of technologies, researchers may not yet be able to oversee and anticipate all of the potential implications. Further development of a research agenda on this topic, the promotion of guidelines and policies, and the publication of case studies that reveal the granularity of individual situations will therefore help raise awareness and assist physicians and institutions in using social media to support existing care services.

  16. The biology of infertility: research advances and clinical challenges

    Matzuk, Martin M; Lamb, Dolores J

    2013-01-01

    Reproduction is required for the survival of all mammalian species, and thousands of essential ‘sex’ genes are conserved through evolution. Basic research helps to define these genes and the mechanisms responsible for the development, function and regulation of the male and female reproductive systems. However, many infertile couples continue to be labeled with the diagnosis of idiopathic infertility or given descriptive diagnoses that do not provide a cause for their defect. For other individuals with a known etiology, effective cures are lacking, although their infertility is often bypassed with assisted reproductive technologies (ART), some accompanied by safety or ethical concerns. Certainly, progress in the field of reproduction has been realized in the twenty-first century with advances in the understanding of the regulation of fertility, with the production of over 400 mutant mouse models with a reproductive phenotype and with the promise of regenerative gonadal stem cells. Indeed, the past six years have witnessed a virtual explosion in the identification of gene mutations or polymorphisms that cause or are linked to human infertility. Translation of these findings to the clinic remains slow, however, as do new methods to diagnose and treat infertile couples. Additionally, new approaches to contraception remain elusive. Nevertheless, the basic and clinical advances in the understanding of the molecular controls of reproduction are impressive and will ultimately improve patient care. PMID:18989307

    Targeted proteomics technique has emerged as a powerful protein quantification tool in systems biology, biomedical research, and increasing for clinical applications. The most widely used targeted proteomics approach, selected reaction monitoring (SRM), also known as multiple reaction monitoring (MRM), can be used for quantification of cellular signaling networks and preclinical verification of candidate protein biomarkers. As an extension to our previous review on advances in SRM sensitivity (Shi et al., Proteomics, 12, 1074–1092, 2012) herein we review recent advances in the method and technology for further enhancing SRM sensitivity (from 2012 to present), and highlighting its broad biomedical applications in human bodily fluids, tissue and cell lines. Furthermore, we also review two recently introduced targeted proteomics approaches, parallel reaction monitoring (PRM) and data-independent acquisition (DIA) with targeted data extraction on fast scanning high-resolution accurate-mass (HR/AM) instruments. Such HR/AM targeted quantification with monitoring all target product ions addresses SRM limitations effectively in specificity and multiplexing; whereas when compared to SRM, PRM and DIA are still in the infancy with a limited number of applications. Thus, for HR/AM targeted quantification we focus our discussion on method development, data processing and analysis, and its advantages and limitations in targeted proteomics. Finally, general perspectives on the potential of achieving both high sensitivity and high sample throughput for large-scale quantification of hundreds of target proteins are discussed.

    Full Text Available Widow spiders have received much attention due to the frequently reported human and animal injures caused by them. Elucidation of the molecular composition and action mechanism of the venoms and toxins has vast implications in the treatment of latrodectism and in the neurobiology and pharmaceutical research. In recent years, the studies of the widow spider venoms and the venom toxins, particularly the α-latrotoxin, have achieved many new advances; however, the mechanism of action of the venom toxins has not been completely clear. The widow spider is different from many other venomous animals in that it has toxic components not only in the venom glands but also in other parts of the adult spider body, newborn spiderlings, and even the eggs. More recently, the molecular basis for the toxicity outside the venom glands has been systematically investigated, with four proteinaceous toxic components being purified and preliminarily characterized, which has expanded our understanding of the widow spider toxins. This review presents a glance at the recent advances in the study on the venoms and toxins from the Latrodectus species.

    2013-12-01

    Making video clips is an engaging way to learn and teach geoscience. As smartphones become increasingly common, it is relatively straightforward for students to produce ';video diaries' by recording their research and learning experience over the course of a science module. Instead of keeping the video diaries for themselves, students may use the social media such as Facebook for sharing their experience and thoughts. There are some potential benefits to link video diaries and social media in pedagogical contexts. For example, online comments on video clips offer useful feedback and learning materials to the students. Students also have the opportunity to engage in geoscience outreach by producing authentic scientific contents at the same time. A video diary project was conducted to test the pedagogical potential of using video diaries on social media in the context of geoscience outreach, undergraduate research and teaching. This project formed part of a problem-based learning module in field geophysics at an archaeological site in the UK. The project involved i) the students posting video clips about their research and problem-based learning in the field on a daily basis; and ii) the lecturer building an online outreach community with partner institutions. In this contribution, I will discuss the implementation of the project and critically evaluate the pedagogical potential of video diaries on social media. My discussion will focus on the following: 1) Effectiveness of video diaries on social media; 2) Student-centered approach of producing geoscience video diaries as part of their research and problem-based learning; 3) Learning, teaching and assessment based on video clips and related commentaries posted on Facebook; and 4) Challenges in creating and promoting online communities for geoscience outreach through the use of video diaries. I will compare the outcomes from this study with those from other pedagogical projects with video clips on geoscience, and

    Full Text Available The Norwegian research programme on advanced robot systems has been focused on sensory control of robots for industrial applications and telerobotics for underwater operations. This paper gives an overview of experimental work and ongoing research. An exciting area in sensory control is visual servoing where camera images at video rate are used to grasp moving objects. Also compliant motion in partially unknown environments is a research topic. New robot control systems have been developed to apply sensory control to robotic manipulators at an acceptable sampling rate. In telerobotics the main work has been on the combination of remote control and local sensory loops in the manipulator. Also in this case visual servoing anti force control are important. The generation and updating of a world model used in a graphic display of the worksite using sensory information has been tested in combination with large delay times in the communication channel. The use of visual and acoustic data for the control of remotely operated vehicles and autonomous underwater vehicles is studied for use in robotic systems. Light-weight robot manipulators with redundant degrees of freedom and high performance joints are being designed for mobile robot applications.

    Autism, a lifelong neuro-developmental disorder is a uniquely human condition. Animal models are not the perfect tools for the full understanding of human development and behavior, but they can be an important place to start. This review focused on the recent updates of animal model research in autism. We have reviewed the publications over the last three decades, which are related to animal model study in autism. Animal models are important because they allow researchers to study the underlying neurobiology in a way that is not possible in humans. Improving the availability of better animal models will help the field to increase the development of medicines that can relieve disabling symptoms. Results from the therapeutic approaches are encouraging remarkably, since some behavioral alterations could be reversed even when treatment was performed on adult mice. Finding an animal model system with similar behavioral tendencies as humans is thus vital for understanding the brain mechanisms, supporting social motivation and attention, and the manner in which these mechanisms break down in autism. The ongoing studies should therefore increase the understanding of the biological alterations associated with autism as well as the development of knowledge-based treatments therapy for those struggling with autism. In this review, we have presented recent advances in research based on animal models of autism, raising hope for understanding the disease biology for potential therapeutic intervention to improve the quality of life of autism individuals.

    The humble house mouse has long been a workhorse model system in biomedical research. The technology for introducing site-specific genome modifications led to Nobel Prizes for its pioneers and opened a new era of mouse genetics. However, this technology was very time-consuming and technically demanding. As a result, many investigators continued to employ easier genome manipulation methods, though resulting models can suffer from overlooked or underestimated consequences. Another breakthrough, invaluable for the molecular dissection of disease mechanisms, was the invention of high-throughput methods to measure the expression of a plethora of genes in parallel. However, the use of samples containing material from multiple cell types could obfuscate data, and thus interpretations. In this review we highlight some important issues in experimental approaches using mouse models for biomedical research. We then discuss recent technological advances in mouse genetics that are revolutionising human disease research. Mouse genomes are now easily manipulated at precise locations thanks to guided endonucleases, such as transcription activator-like effector nucleases (TALENs) or the CRISPR/Cas9 system, both also having the potential to turn the dream of human gene therapy into reality. Newly developed methods of cell type-specific isolation of transcriptomes from crude tissue homogenates, followed by detection with next generation sequencing (NGS), are vastly improving gene regulation studies. Taken together, these amazing tools simplify the creation of much more accurate mouse models of human disease, and enable the extraction of hitherto unobtainable data.

    The NATO Advanced Research Institute on Search Theory and Appli­ cations was held at the Hotel Algarve in Praia Da Rocha, Portugal, from March 26 through March 30, 1979, and was sponsored by the NATO Special Programme Panel on Systems Science. There were forty-one participants representing a wide range of backgrounds and interests. The purpose of the institute was to bring together people working in search theory and applications with potential users of search techniques to stimulate the increased application of recent­ ly developed search technology to civilian problems such as search and rescue, mineral exploration, surveillance, and fishing. Con­ versely, it was felt that by exposing search analysts to potential applications and new problems, they would be stimulated to develop new techniques for these applications and problems. The exchange of ideas and problems necessary to accomplish these goals was provided in the meeting workshops. There were three workshops, Search and Rescue, Exploration, and Sur...

    With the dissolution of the Soviet Union the nuclear threats facing the world are constantly evolving and have grown more complex since the end of the Cold War. The diversion of complete weapon systems or nuclear material to rogue nations and terrorist organizations has increased. The events of the past years have proved the necessity to reevaluate these threats on a level never before considered.  In recognition that no single country possesses all of the answers to the critical scientific, institutional and legal questions associated with combating nuclear and radiological terrorism, the NATO Advanced Research Workshop on “Preparedness for Nuclear and Radiological Threats” and this proceeding was structured to promote wide-ranging, multi-national exploration of critical technology needs and underlying scientific challenges to reducing the threat of nuclear/radiological terrorism; to illustrate through country-specific presentations how resulting technologies were used in national programs; and to outli...

    Manufactured nanomaterials (MNMs) are rapidly being incorporated into a wide variety of commercial products with significant potential for environmental release, which calls for eco-responsible design and disposal of nanoenabled products. Critical research needs to advance this urgent priority include (1) structure-activity relationships to predict functional stability and chemistry of MNMs in the environment and to discern properties that increase their bioavailability, bioaccumulation, and toxicity; (2) standardized protocols to assess MNM bioavailability, trophic transfer, and sublethal effects; and (3) validated multiphase fate and transport models that consider various release scenarios and predict the form and concentration of MNMs at the point of exposure. These efforts would greatly benefit from the development of robust analytical techniques to characterize and to track MNMs in the environment and to validate models and from shared reference MNM libraries.

    Lutein, a kind of oxycarotenoid, can pass the blood brain barrier and preferentially accumulate in the human brain, which is the most abundant carotenoid in human brain. Evidence from multiple studies suggested that lutein was closely related to age-related cognitive decline and risk of Alzheimer's disease (AD) in human. Dietary, plasma and brain concentrations of lutein were negatively associated with age-related cognitive decline. Lutein concentrations in plasma and brain were significantly lower in AD patients than those of health control. In human brain, lutein was the sole carotenoid which consistently associated with a range of cognitive function measures. In elderly women, lutein supplement can improve the cognitive function. In this article, we systematically reviewed the literature on the role of lutein in age-related cognitive decline and alzheimer's disease and its possible mechanisms. It may prove some benefit information for the advanced research and prevention of AD.

    The engineering application of natural hyperaccumulators in removing or inactivating metal pollutants from soil and surface water in field trials mostly presents the insurmountable shortcoming of low efficiency owing to their little biomass and slow growth. Based on further understanding of the molecular mechanism of metal uptake, translocation, and also the separation, identification, and cloning of some related functional genes, this article highlights and summarizes in detail the advances in research on transgenic techniques, such as Agrobacterium tumefaciens-mediated transformation and particle bombardment, in breeding of plants for metal resistance and accumulation, and points out that deepening the development of transgenic plants is one of the efficient approaches to improving phytoremediation efficiency of metal-contaminated environments. From the viewpoint of sustainable development, governments should strengthen support to the development of genetic engineering for metal resistance and accumulation in plants.

    Full Text Available Pancreatic cancer (PC is one of common malignant digestive diseases. It is mostly diagnosed at advanced stage, with an extremely poor progression. The relationship between diabetes and PC was shown by numerous epidemiological studies for decades. Retrospective clinical studies and research on molecular mechanisms in recent years have led to a new understanding of the relationship between diabetes, especially new-onset diabetes, and PC, the effect of antidiabetic medication on PC, and the molecular mechanisms underlying the connection between diabetes and PC. It is suggested by recent data that long-standing diabetes is one of the risk factors for PC development, new-onset diabetes may facilitate early diagnosis of PC, diabetes may have an impact on the prognosis of PC, the option of antidiabetic medication may influence the incidence of PC, and exploring the molecular mechanisms underlying the association between diabetes and PC may help to identify the new therapeutic target for PC.

    Multiple small-scale projects have been undertaken to investigate advanced instrumentation solutions for safeguard measurement challenges associated with advanced fuel cycle facilities and next-generation fuel reprocessing installations. These activities are in support of the U.S. Department of Energy's Fuel Cycle Research and Development program and its Materials Protection, Accounting, and Control for Transmutation (MPACT) campaign. 1) Work was performed in a collaboration with the University of Michigan (Prof. Sara Pozzi, co-PI) to investigate the use of liquid-scintillator radiation detectors for assaying mixed-oxide (MOX) fuel, to characterize its composition and to develop advanced digital pulse-shape discrimination algorithms for performing time-correlation measurements in the MOX fuel environment. This work included both simulations and experiments and has shown that these techniques may provide a valuable approach for use within advanced safeguard measurement scenarios. 2) Work was conducted in a collaboration with Oak Ridge National Laboratory (Dr. Paul Hausladen, co-PI) to evaluate the strengths and weaknesses of the fast-neutron coded-aperture imaging technique for locating and characterizing fissile material, and as a tool for performing hold-up measurements in fissile material handling facilities. This work involved experiments at Idaho National Laboratory, using MOX fuel and uranium metal, in both passive and active interrogation configurations. A complete analysis has not yet been completed but preliminary results suggest several potential uses for the fast neutron imaging technique. 3) Work was carried out to identify measurement approaches for determining nitric acid concentration in the range of 1 – 4 M and beyond. This work included laboratory measurements to investigate the suitability of prompt-gamma neutron activation analysis for this measurement and product reviews of other commercial solutions.

    As commercial space flights have become feasible and long-term extraterrestrial missions are planned, it is imperative that the impact of space travel and the space environment on human physiology be thoroughly characterized. Scrutinizing the effects of potentially detrimental factors such as ionizing radiation and microgravity at the cellular and tissue level demands adequate visualization technology. Advanced light microscopy (ALM) is the leading tool for non-destructive structural and functional investigation of static as well as dynamic biological systems. In recent years, technological developments and advances in photochemistry and genetic engineering have boosted all aspects of resolution, readout and throughput, rendering ALM ideally suited for biological space research. While various microscopy-based studies have addressed cellular response to space-related environmental stressors, biological endpoints have typically been determined only after the mission, leaving an experimental gap that is prone to bias results. An on-board, real-time microscopical monitoring device can bridge this gap. Breadboards and even fully operational microscope setups have been conceived, but they need to be rendered more compact and versatile. Most importantly, they must allow addressing the impact of gravity, or the lack thereof, on physiologically relevant biological systems in space and in ground-based simulations. In order to delineate the essential functionalities for such a system, we have reviewed the pending questions in space science, the relevant biological model systems, and the state-of-the art in ALM. Based on a rigorous trade-off, in which we recognize the relevance of multi-cellular systems and the cellular microenvironment, we propose a compact, but flexible concept for space-related cell biological research that is based on light sheet microscopy.

    Exercise countermeasures provide benefits that are crucial for successful human spaceflight, to mitigate the spaceflight physiological deconditioning which occurs during exposure to microgravity. The NASA Human Research Program (HRP) within the Human Exploration and Operations Mission Directorate (HEOMD) is managing next generation Advanced Exercise Concepts (AEC) requirements development and candidate technology maturation to Technology Readiness Level (TRL) 7 (ground prototyping and flight demonstration) for all exploration mission profiles from Multi Purpose Crew Vehicle (MPCV) Exploration Missions (up to 21 day duration) to Mars Transit (up to 1000 day duration) missions. These validated and optimized exercise countermeasures systems will be provided to the ISS Program and MPCV Program for subsequent flight development and operations. The International Space Station (ISS) currently has three major pieces of operational exercise countermeasures hardware: the Advanced Resistive Exercise Device (ARED), the second-generation (T2) treadmill, and the cycle ergometer with vibration isolation system (CEVIS). This suite of exercise countermeasures hardware serves as a benchmark and is a vast improvement over previous generations of countermeasures hardware, providing both aerobic and resistive exercise for the crew. However, vehicle and resource constraints for future exploration missions beyond low Earth orbit will require that the exercise countermeasures hardware mass, volume, and power be minimized, while preserving the current ISS capabilities or even enhancing these exercise capabilities directed at mission specific physiological functional performance and medical standards requirements. Further, mission-specific considerations such as preservation of sensorimotor function, autonomous and adaptable operation, integration with medical data systems, rehabilitation, and in-flight monitoring and feedback are being developed for integration with the exercise

    Full Text Available Internet technology today shows a quick progress, and social networks increase their number of users on each day. Social networking, which is one of the main indicators of th e technology era, attracts people of all ages while the virtual world goes beyond the real life via the applications it offers. Especially young people show an intense interest in social media which is an extension of the Internet technology. Social media addiction is increasing both in Turkey and all around the world. This study aims to determine the level of social media addiction in young people in Turkey, and to make suggestions on the prevention of the addiction while stating the current work carried o ut on the subject in Turkey. Survey type research model is used in the study, and social media addiction is examined in depth to determine causes of the addiction among young people. In this study, the addiction factor of the Social Networking Status Scale is used as a data collection tool to measure social media addiction among young people. The scale has three factors including addiction, ethics and convergence, and it is a reliable and valid scale, as the reliability and validity of the scale had been te sted. The study is conducted on 271 students between the ages of 13 - 19. It has been found that gender (t=0.406; P>0.05 makes no significant difference in social media addiction while the factors of age (F= 6.256; P<0.05, daily time spent on the Internet ( F= 44.036; P<0.05 and daily frequency of visiting social media profiles (F= 53.56; P<0.05 make significant differences in addiction level. The results have showed that low addiction level of 14 - year group increases with age up to 17 years, and the level de creases in 18 - year group. Social media addiction level shows a dramatic increase also in the case of daily time spent on the Internet increases. More frequent d aily visits to social media profiles increase the addiction as well. The study also provides sug

    Analyzing news media allows obesity policy researchers to understand popular conceptions about obesity, which is important for targeting health education and policies. A persistent dilemma is that investigators have to read and manually classify thousands of individual news articles to identify how obesity and obesity-related policy proposals may be described to the public in the media. A machine learning method called "automated content analysis" that permits researchers to train computers to "read" and classify massive volumes of documents was demonstrated. 14,302 newspaper articles that mentioned the word "obesity" during 2011-2012 were identified. Four states that vary in obesity prevalence and policy (Alabama, California, New Jersey, and North Carolina) were examined. The reliability of an automated program to categorize the media's framing of obesity as an individual-level problem (e.g., diet) and/or an environmental-level problem (e.g., obesogenic environment) was tested. The automated program performed similarly to human coders. The proportion of articles with individual-level framing (27.7-31.0%) was higher than the proportion with neutral (18.0-22.1%) or environmental-level framing (16.0-16.4%) across all states and over the entire study period (Pobesity concepts are communicated and propagated in news media was demonstrated. © 2014 The Obesity Society.

    2005-01-01

    As an important component of FLUXNET, Asia is increasingly becoming the hotspot in global carbon research for its vast territory, complex climate type and vegetation diversity. The present three regional flux observation networks in Asia (i.e. AsiaFlux, KoFlux and ChinaFLUX)have 54 flux observation sites altogether, covering tropic rainforest, evergreen broad-leaved forest, broad-leaved and coniferous mixed forest, shrubland, grassland, alpine meadow and cropland ecosystems with a latitudinal distribution from 2°N to 63°N. Long-term and continuous fluxes of carbon dioxide, water vapor and energy between the biosphere and atmosphere are mainly measured with eddy covariance technique to (1) quantify and compare the carbon, water and energy budgets across diverse ecosystems; (2) quantify the environmental and biotic controlling mechanism on ecosystem carbon, water and energy fluxes; (3) validate the soil-vegetation-atmosphere model; and (4) serve the integrated study of terrestrial ecosystem carbon and water cycle. Over the last decades, great advancements have been made in the theory and technology of flux measurement, ecosystem flux patterns, simulation and scale conversion by Asian flux community. The establishment of ChinaFLUX has greatly filled the gap of flux observation and research in Eurasia. To further promote the flux measurement and research,accelerate data sharing and improve the data quality, it is necessary to present a methodological system of flux estimation and evaluation over complex terrain and to develop the integrated research that combines the flux measurement, stable isotope measurement, remote sensing observation and GIS technique. It also requires the establishment of the Joint Committee of Asian Flux Network in the Asia-Pacific region in order to promote the cooperation and communication of ideas and data by supporting project scientists, workshops and visiting scientists.

  9. Astrid-2, an advanced microsatellite for auroral research

    Directory of Open Access Journals (Sweden)

    G. T. Marklund

    Full Text Available The successful launch of the Swedish microsatellite Astrid-2 in December 1998 began a new era of auroral research, with advanced microprobes of 30 kg or less used as research tools. Innovative technologies and low-mass solutions were used for the sensors and deployment systems to allow a fairly complete set of scientific instruments within the 10 kg allocated for the scientific payload. A newly developed wire boom deployment system proved to function excellently. During its seven month lifetime Astrid-2 collected more than 26 Gbytes of high-quality data of auroral electric and magnetic fields, and auroral particle and plasma characteristics from approximately 3000 orbits at an inclination of 83° and an altitude of about 1000 km. Scientific results cover a broad range of topics, from the physics of energization of auroral particles to how the magnetosphere responds to the energy input from the solar wind and global magnetic field modelling. The fulfilment of both the technological and the scientific mission objectives has opened entirely new possibilities to carry out low-budget multipoint measurements in near-Earth space.

    2008-12-01

    Peanut (Arachis hypogaea L.) is a major oil-bearing crop in the world, and as well, an important resource of plant protein and a main raw material for food processing. With the increasing of its direct human consumption and food processing, the Cd concentration in peanut kernel has aroused great concern in recent years. China is a main country of the production and exportation of peanut, but the Cd enrichment in peanut kernel is the main obstacle for its peanut export trade. In this paper, the research advances in Cd pollution of peanut kernel were reviewed, based on the characteristics and mechanisms of Cd accumulation and distribution in peanut kernel, the intra-specific variation of kernel Cd content, and the measures in controlling kernel Cd content. Two strategies were put forward for controlling Cd pollution of peanut kernel, i.e., to reduce the Cd uptake by main root system of peanut plant, and to control the transference of Cd from root to fruit (kernel). In order to applying the strategies effectively, researches on the mechanisms of Cd accumulation in peanut kernel should be enhanced in three aspects, i.e., root vitality and its relationship with Cd accumulation in kernel, mechanism of fruit Cd absorption and its contribution to kernel Cd content, and mechanism of Cd transference in plants and its effects on kernel Cd content.

    2016-01-01

    Microscopic techniques are among the few approaches that have survived the test of time. Being invented half way the seventeenth century by Antonie van Leeuwenhoek and Robert Hooke, this technology is still essential in modern biomedical labs. Many microscopy techniques have been used in ENS research to guide researchers in their dissections and later to enable electrode recordings. Apart from this, microscopy has been instrumental in the identification of subpopulations of cells in the ENS, using a variety of staining methods. A significant step forward in the use of microscopy was the introduction of fluorescence approaches. Due to the fact that intense excitation light is now filtered away from the longer wavelength emission light, the contrast can be improved drastically, which helped to identify subpopulations of enteric neurons in a variety of species. Later functionalized fluorescent probes were used to measure and film activity in muscle and neuronal cells. Another important impetus to the use of microscopy was the discovery and isolation of the green fluorescent protein (GFP), as it gave rise to the development of many different color variants and functionalized constructs. Recent advances in microscopy are the result of a continuous search to enhance contrast between the item of interest and its background but also to improve resolving power to tell two small objects apart. In this chapter three different microscopy approaches will be discussed that can aid to improve our understanding of ENS function within the gut wall.

    Champod, Christophe

    2015-01-01

    This paper will discuss the major developments in the area of fingerprint identification that followed the publication of the National Research Council (NRC, of the US National Academies of Sciences) report in 2009 entitled: Strengthening Forensic Science in the United States: A Path Forward. The report portrayed an image of a field of expertise used for decades without the necessary scientific research-based underpinning. The advances since the report and the needs in selected areas of fingerprinting will be detailed. It includes the measurement of the accuracy, reliability, repeatability and reproducibility of the conclusions offered by fingerprint experts. The paper will also pay attention to the development of statistical models allowing assessment of fingerprint comparisons. As a corollary of these developments, the next challenge is to reconcile a traditional practice dominated by deterministic conclusions with the probabilistic logic of any statistical model. There is a call for greater candour and fingerprint experts will need to communicate differently on the strengths and limitations of their findings. Their testimony will have to go beyond the blunt assertion of the uniqueness of fingerprints or the opinion delivered ispe dixit. PMID:26101284

    Smith, V.E.

    1994-05-01

    Numerous studies have been conducted in five principal areas: oil shale, tar sand, underground coal gasification, advanced process technology, and advanced fuels research. In subsequent years, underground coal gasification was broadened to be coal research, under which several research activities were conducted that related to coal processing. The most significant change occurred in 1989 when the agreement was redefined as a Base Program and a Jointly Sponsored Research Program (JSRP). Investigations were conducted under the Base Program to determine the physical and chemical properties of materials suitable for conversion to liquid and gaseous fuels, to test and evaluate processes and innovative concepts for such conversions, to monitor and determine environmental impacts related to development of commercial-sized operations, and to evaluate methods for mitigation of potential environmental impacts. This report is divided into two volumes: Volume 1 consists of 28 summaries that describe the principal research efforts conducted under the Base Program in five topic areas. Volume 2 describes tasks performed within the JSRP. Research conducted under this agreement has resulted in technology transfer of a variety of energy-related research information. A listing of related publications and presentations is given at the end of each research topic summary. More specific and detailed information is provided in the topical reports referenced in the related publications listings.

    Educating young scientists and building capacity on a global scale is pivotal towards better understanding and managing our water resources. Based on this premise the ARCHES (Advancing Research & Capacity in Hydrologic Education and Science) program has been established. This abstract provides an overview of the program, links to access information, and describes the activities and outcomes of student participants from the Middle East and North Africa. The ARCHES program (http://arches.wrrs.uga.edu) is an integrated hydrologic education approach using online courses, field programs, and various hands-on workshops. The program aims to enable young scientists to effectively perform the high level research that will ultimately improve quality of life, enhance science-based decision making, and facilitate collaboration. Three broad, interlinked sets of activities are incorporated into the ARCHES program: (A1) the development of technical expertise, (A2) the development of professional contacts and skills, and (A3) outreach and long-term sustainability. The development of technical expertise (A1) is implemented through three progressive instructional sections. Section 1: Students were guided through a series of online lectures and exercises (Moodle: http://wrrs.uga.edu/moodle) covering three main topics (Remote Sensing, GIS, and Hydrologic Modeling). Section 2: Students participated in a hands-on workshop hosted at the University of Georgia's Water Resources and Remote Sensing Laboratory (WRRSL). Using ENVI, ArcGIS, and ArcSWAT, students completed a series of lectures and real-world applications (e.g., Development of Hydrologic Models). Section 3: Students participated in field studies (e.g., measurements of infiltration, recharge, streamflow, and water-quality parameters) conducted by U.S. partners and international collaborators in the participating countries. The development of professional contacts and skills (A2) was achieved through the promotion of networking

    2007-09-01

    Full Text Available This useful handbook introduces the present state of qualitative methodology in German media research. While its formal focus is on media, it covers many aspects which are of general interest. The chapters are short and provide useful examples of the application of different methods. The book proceeds from theory via data collection to analysis and meta-methodological reflections. In some chapters, it is not always clear whether data collection or analysis is the focus. The book also indicates three desiderata of qualitative methodology today: 1. the logics of sampling are often neglected; 2. the process of analysis beyond structuring the material is not sufficiently clear; and 3. comprehensive criteria for the validity of qualitative research are still lacking.

    2016-02-03

    Over a full two day period, February 2–3, 2016, the Office of High Energy Physics convened a workshop in Gaithersburg, MD to seek community input on development of an Advanced Accelerator Concepts (AAC) research roadmap. The workshop was in response to a recommendation by the HEPAP Accelerator R&D Subpanel [1] [2] to “convene the university and laboratory proponents of advanced acceleration concepts to develop R&D roadmaps with a series of milestones and common down selection criteria towards the goal for constructing a multi-TeV e+e– collider” (the charge to the workshop can be found in Appendix A). During the workshop, proponents of laser-driven plasma wakefield acceleration (LWFA), particle-beam-driven plasma wakefield acceleration (PWFA), and dielectric wakefield acceleration (DWFA), along with a limited number of invited university and laboratory experts, presented and critically discussed individual concept roadmaps. The roadmap workshop was preceded by several preparatory workshops. The first day of the workshop featured presentation of three initial individual roadmaps with ample time for discussion. The individual roadmaps covered a time period extending until roughly 2040, with the end date assumed to be roughly appropriate for initial operation of a multi-TeV e+e– collider. The second day of the workshop comprised talks on synergies between the roadmaps and with global efforts, potential early applications, diagnostics needs, simulation needs, and beam issues and challenges related to a collider. During the last half of the day the roadmaps were revisited but with emphasis on the next five to ten years (as specifically requested in the charge) and on common challenges. The workshop concluded with critical and unanimous endorsement of the individual roadmaps and an extended discussion on the characteristics of the common challenges.

  18. Learning from Mistakes in the Media to Improve the Communication of Wood Bioenergy Research

    Directory of Open Access Journals (Sweden)

    Brooks C. Mendell

    2013-11-01

    Full Text Available Successful applied research into wood bioenergy requires communication of meaningful insights to inform decision-makers and the general public. Effective communication strategies make such insights accessible. However, recent media reports often exhibit a near total absence of findings from peer-reviewed or quantitative research, highlighting a failure to communicate between applied researchers and reporters. As a result, the general public’s understanding of wood-based bioenergy remains incomplete. At a minimum, researchers can address three common lapses when communicating results of their research related to wood-based energy to increase the public’s access to technical results. First, provide context to give policymakers a sense, on a relative basis, of the importance of a given issue. Second, properly distinguish between “causal” relationships and mere happenstance or correlations. And finally, confirm facts and conclusions. Faulty assertions can cast doubts on the broader work and body of research.

    2016-04-01

    Full Text Available Social media posts are full of potential for data mining and analysis. Recognizing this potential, platform providers increasingly restrict free access to such data. This shift provides new challenges for social scientists and other non-profit researchers who seek to analyze public posts with a purpose of better understanding human interaction and improving the human condition. This paper seeks to outline some of the recent changes in social media data analysis, with a focus on Twitter, specifically. Using Twitter data from a 24-hour period following The Sisters in Spirit Candlelight Vigil, sponsored by the Native Women’s Association of Canada, this article compares three free-use Twitter application programming interfaces for capturing tweets and enabling analysis. Although recent Twitter data restrictions limit free access to tweets, there are many dynamic options for social scientists to choose from in the capture and analysis of Twitter and other social media platform data. This paper calls for critical social media data analytics combined with traditional, qualitative methods to address the developing ‘data gold rush.’

  1. Advanced quantitative measurement methodology in physics education research

    Science.gov (United States)

    Wang, Jing

    The ultimate goal of physics education research (PER) is to develop a theoretical framework to understand and improve the learning process. In this journey of discovery, assessment serves as our headlamp and alpenstock. It sometimes detects signals in student mental structures, and sometimes presents the difference between expert understanding and novice understanding. Quantitative assessment is an important area in PER. Developing research-based effective assessment instruments and making meaningful inferences based on these instruments have always been important goals of the PER community. Quantitative studies are often conducted to provide bases for test development and result interpretation. Statistics are frequently used in quantitative studies. The selection of statistical methods and interpretation of the results obtained by these methods shall be connected to the education background. In this connecting process, the issues of educational models are often raised. Many widely used statistical methods do not make assumptions on the mental structure of subjects, nor do they provide explanations tailored to the educational audience. There are also other methods that consider the mental structure and are tailored to provide strong connections between statistics and education. These methods often involve model assumption and parameter estimation, and are complicated mathematically. The dissertation provides a practical view of some advanced quantitative assessment methods. The common feature of these methods is that they all make educational/psychological model assumptions beyond the minimum mathematical model. The purpose of the study is to provide a comparison between these advanced methods and the pure mathematical methods. The comparison is based on the performance of the two types of methods under physics education settings. In particular, the comparison uses both physics content assessments and scientific ability assessments. The dissertation includes three

    1997-12-31

    The great potential of hydrogen production by microalgal water splitting is predicated on quantitative measurement of the algae`s hydrogen-producing capability, which is based on the following: (1) the photosynthetic unit size of hydrogen production; (2) the turnover time of photosynthetic hydrogen production; (3) thermodynamic efficiencies of conversion of light energy into the Gibbs free energy of molecular hydrogen; (4) photosynthetic hydrogen production from sea water using marine algae; (5) the potential for research advances using modern methods of molecular biology and genetic engineering to maximize hydrogen production. ORNL has shown that sustained simultaneous photoevolution of molecular hydrogen and oxygen can be performed with mutants of the green alga Chlamydomonas reinhardtii that lack a detectable level of the Photosystem I light reaction. This result is surprising in view of the standard two-light reaction model of photosynthesis and has interesting scientific and technological implications. This ORNL discovery also has potentially important implications for maximum thermodynamic conversion efficiency of light energy into chemical energy by green plant photosynthesis. Hydrogen production performed by a single light reaction, as opposed to two, implies a doubling of the theoretically maximum thermodynamic conversion efficiency from {approx}10% to {approx}20%.

  4. Review: Advances in delta-subsidence research using satellite methods

    Science.gov (United States)

    Higgins, Stephanie A.

    2016-05-01

    Most of the world's major river deltas are sinking relative to local sea level. The effects of subsidence can include aquifer salinization, infrastructure damage, increased vulnerability to flooding and storm surges, and permanent inundation of low-lying land. Consequently, determining the relative importance of natural vs. anthropogenic pressures in driving delta subsidence is a topic of ongoing research. This article presents a review of knowledge with respect to delta surface-elevation loss. The field is rapidly advancing due to applications of space-based techniques: InSAR (interferometric synthetic aperture radar), GPS (global positioning system), and satellite ocean altimetry. These techniques have shed new light on a variety of subsidence processes, including tectonics, isostatic adjustment, and the spatial and temporal variability of sediment compaction. They also confirm that subsidence associated with fluid extraction can outpace sea-level rise by up to two orders of magnitude, resulting in effective sea-level rise that is one-hundred times faster than the global average rate. In coming years, space-based and airborne instruments will be critical in providing near-real-time monitoring to facilitate management decisions in sinking deltas. However, ground-based observations continue to be necessary for generating complete measurements of surface-elevation change. Numerical modeling should seek to simulate couplings between subsidence processes for greater predictive power.

    Full Text Available Aquaporins (AQPs are proteinaceous channels widespread in nature where they allow facilitated permeation of water and uncharged through cellular membranes. AQPs play a number of important roles in both health and disease. This review focuses on the most recent advances and research trends regarding the expression and modulation, as well as physiological and pathophysiological functions of AQPs in hepatocytes and Sertoli cells (SCs. Besides their involvement in bile formation, hepatocyte AQPs are involved in maintaining energy balance acting in hepatic gluconeogenesis and lipid metabolism, and in critical processes such as ammonia detoxification and mitochondrial output of hydrogen peroxide. Roles are played in clinical disorders including fatty liver disease, diabetes, obesity, cholestasis, hepatic cirrhosis and hepatocarcinoma. In the seminiferous tubules, particularly in SCs, AQPs are also widely expressed and seem to be implicated in the various stages of spermatogenesis. Like in hepatocytes, AQPs may be involved in maintaining energy homeostasis in these cells and have a major role in the metabolic cooperation established in the testicular tissue. Altogether, this information represents the mainstay of current and future investigation in an expanding field.

    Models of attention often distinguish among attention subtypes, with classic models separating orienting, switching, and sustaining functions. Compared with other forms of attention, the neurophysiological basis of sustaining attention has received far less notice, yet it is known that momentary failures of sustained attention can have far-ranging negative effects in healthy individuals, and lasting sustained attention deficits are pervasive in clinical populations. In recent years, however, there has been increased interest in characterizing moment-to-moment fluctuations in sustained attention, in addition to the overall vigilance decrement, and understanding how these neurocognitive systems change over the life span and across various clinical populations. The use of novel neuroimaging paradigms and statistical approaches has allowed for better characterization of the neural networks supporting sustained attention and has highlighted dynamic interactions within and across multiple distributed networks that predict behavioral performance. These advances have also provided potential biomarkers to identify individuals with sustained attention deficits. These findings have led to new theoretical models explaining why sustaining focused attention is a challenge for individuals and form the basis for the next generation of sustained attention research, which seeks to accurately diagnose and develop theoretically driven treatments for sustained attention deficits that affect a variety of clinical populations. © 2017 New York Academy of Sciences.

  11. The Cultivation of Arabidopsis for Experimental Research Using Commercially Available Peat-Based and Peat-Free Growing Media.

    Directory of Open Access Journals (Sweden)

    Tiffany Drake

    Full Text Available Experimental research involving Arabidopsis thaliana often involves the quantification of phenotypic traits during cultivation on compost or other growing media. Many commercially-available growing media contain peat, but peat extraction is not sustainable due to its very slow rate of formation. Moreover, peat extraction reduces peatland biodiversity and releases stored carbon and methane into the atmosphere. Here, we compared the experimental performance of Arabidopsis on peat-based and several types of commercially-available peat-free growing media (variously formed from coir, composted bark, wood-fibre, and domestic compost, to provide guidance for reducing peat use in plant sciences research with Arabidopsis. Arabidopsis biomass accumulation and seed yield were reduced by cultivation on several types of peat-free growing media. Arabidopsis performed extremely poorly on coir alone, presumably because this medium was completely nitrate-free. Some peat-free growing media were more susceptible to fungal contamination. We found that autoclaving of control (peat-based growing media had no effect upon any physiological parameters that we examined, compared with non-autoclaved control growing media, under our experimental conditions. Overall, we conclude that Arabidopsis performs best when cultivated on peat-based growing media because seed yield was almost always reduced when peat-free media were used. This may be because standard laboratory protocols and growth conditions for Arabidopsis are optimized for peat-based media. However, during the vegetative growth phase several phenotypic traits were comparable between plants cultivated on peat-based and some peat-free media, suggesting that under certain circumstances peat-free media can be suitable for phenotypic analysis of Arabidopsis.

    Full Text Available Systemteoretisk medieforskning rejser spørgsmålet om, hvorvidt massemedierne udgør en samlet institution, eller om medierne, i kraft af deres indbyrdes forskelle, skal betragtes uafhængigt af hinanden. Ved at indskrive medierne i en generel samfundsteori fremstiller systemteorien medierne som et autonomt funktionssystem. Denne bestræbelse kommer tydeligst til udtryk i identifikationen af en fælles kode for massemediernes system. Med udgangspunkt i Niklas Luhmanns medieteori foretager nærværende artikel en kritisk gennemgang af den systemteoretiske medieforsknings kodediskussion. Første del præsenterer kort systemteoriens kodebegreb og Luhmanns bestemmelse af mediesystemet som organiseret omkring koden information. Den midterste del gennemgår en række alternative forslag til denne kodedefinition, hvilket illustrerer omfanget, men også nogle af begrænsningerne, ved systemteoretisk medieforskning. Sidste del foretager en kritisk diskussion af systemteoriens kodeproblematik og viser, hvordan en ensidig kodefokusering står i vejen for en fortsat udforskning af vilkårene for mediesystemets udvikling og autonomi.Systems theoretical media research raises the question whether the mass media constitute a unified institution, or whether the media, due to their internal differences, should be considered individually and independent of each other. By inscribing the media in a general social theory, systems theory conceptualises the media as an autonomous functional system. This intention is most clearly illustrated by the efforts to identify a shared code for the entire media system. Based on the media theory of Niklas Luhmann, this paper offers a critical presentation of the code discussion within systems theoretical media research. The first part of the paper briefly introduces the systems theoretical notion of a code as well as Luhmann’s definition of the media system as organised and regulated by the code of information.

    Strategies for constructing and maintaining cross-disciplinary teams are in their infancy. We outline strategies to support one form, transdisciplinary research, in a major initiative of the National Cancer Institute, the Transdisciplinary Research in Energetics and Cancer 2 (TREC2) initiative. Discussion of the TREC2 sites' experiences with transdisciplinarity is structured around a conceptual model that identifies four iterative phases of transdisciplinary research. An active coordination center, regular face-to-face meetings, and input from external advisors were instrumental in moving TREC2 to the translation phase. The possibilities for advancements in the science of energetics and cancer increased as investigator ties became denser. TREC2 can be seen as a flagship effort in transdisciplinary science that provides lessons on moving ideas from development to translation.

  17. A programmable sound processor for advanced hearing aid research.

    Science.gov (United States)

    McDermott, H

    1998-03-01

    A portable sound processor has been developed to facilitate research on advanced hearing aids. Because it is based on a digital signal processing integrated circuit (Motorola DSP56001), it can readily be programmed to execute novel algorithms. Furthermore, the parameters of these algorithms can be adjusted quickly and easily to suit the specific hearing characteristics of users. In the processor, microphone signals are digitized to a precision of 12 bits at a sampling rate of approximately 12 kHz for input to the DSP device. Subsequently, processed samples are delivered to the earphone by a novel, fully-digital class-D driver. This driver provides the advantages of a conventional class-D amplifier (high maximum output, low power consumption, low distortion) without some of the disadvantages (such as the need for precise analog circuitry). In addition, a cochlear implant driver is provided so that the processor is suitable for hearing-impaired people who use an implant and an acoustic hearing aid together. To reduce the computational demands on the DSP device, and therefore the power consumption, a running spectral analysis of incoming signals is provided by a custom-designed switched-capacitor integrated circuit incorporating 20 bandpass filters. The complete processor is pocket-sized and powered by batteries. An example is described of its use in providing frequency-shaped amplification for aid users with severe hearing impairment. Speech perception tests confirmed that the processor performed significantly better than the subjects' own hearing aids, probably because the digital filter provided a frequency response generally closer to the optimum for each user than the simpler analog aids.

  1. Communication about scientific uncertainty in environmental nanoparticle research - a comparison of scientific literature and mass media

    Science.gov (United States)

    Heidmann, Ilona; Milde, Jutta

    2014-05-01

    The research about the fate and behavior of engineered nanoparticles in the environment is despite its wide applications still in the early stages. 'There is a high level of scientific uncertainty in nanoparticle research' is often stated in the scientific community. Knowledge about these uncertainties might be of interest to other scientists, experts and laymen. But how could these uncertainties be characterized and are they communicated within the scientific literature and the mass media? To answer these questions, the current state of scientific knowledge about scientific uncertainty through the example of environmental nanoparticle research was characterized and the communication of these uncertainties within the scientific literature is compared with its media coverage in the field of nanotechnologies. The scientific uncertainty within the field of environmental fate of nanoparticles is by method uncertainties and a general lack of data concerning the fate and effects of nanoparticles and their mechanisms in the environment, and by the uncertain transferability of results to the environmental system. In the scientific literature, scientific uncertainties, their sources, and consequences are mentioned with different foci and to a different extent. As expected, the authors in research papers focus on the certainty of specific results within their specific research question, whereas in review papers, the uncertainties due to a general lack of data are emphasized and the sources and consequences are discussed in a broader environmental context. In the mass media, nanotechnology is often framed as rather certain and positive aspects and benefits are emphasized. Although reporting about a new technology, only in one-third of the reports scientific uncertainties are mentioned. Scientific uncertainties are most often mentioned together with risk and they arise primarily from unknown harmful effects to human health. Environmental issues itself are seldom mentioned

  4. New media and tobacco control.

    Science.gov (United States)

    Freeman, Becky

    2012-03-01

    This paper reviews how the tobacco industry is promoting its products online and examines possible regulation models to limit exposure to this form of marketing. Opportunities to use new media to advance tobacco control are also discussed and future research possibilities are proposed. Published articles and grey literature reports were identified through searches of the electronic databases, PUBMED and Google Scholar using a combination of the following search terms: tobacco or smoking and new media, online media, social media, internet media, Web 2.0, Facebook, YouTube and Twitter. A possible obstacle to fully realising the benefits of regulating tobacco marketing activities and effectively communicating tobacco control messages is the rapid evolution of the media landscape. New media also offer the tobacco industry a powerful and efficient channel for rapidly countering the denormalising strategies and policies of tobacco control. Evidence of tobacco promotion through online media is emerging, with YouTube being the most researched social media site in the tobacco control field. The explosive rise in Internet use and the shift to these new media being driven by consumer generated content through social platforms may mean that fresh approaches to regulating tobacco industry marketing are needed.

  5. Build your own social network laboratory with Social Lab: a tool for research in social media.

    Garaizar, Pablo; Reips, Ulf-Dietrich

    2014-06-01

    Social networking has surpassed e-mail and instant messaging as the dominant form of online communication (Meeker, Devitt, & Wu, 2010). Currently, all large social networks are proprietary, making it difficult to impossible for researchers to make changes to such networks for the purpose of study design and access to user-generated data from the networks. To address this issue, the authors have developed and present Social Lab, an Internet-based free and open-source social network software system available from http://www.sociallab.es . Having full availability of navigation and communication data in Social Lab allows researchers to investigate behavior in social media on an individual and group level. Automated artificial users ("bots") are available to the researcher to simulate and stimulate social networking situations. These bots respond dynamically to situations as they unfold. The bots can easily be configured with scripts and can be used to experimentally manipulate social networking situations in Social Lab. Examples for setting up, configuring, and using Social Lab as a tool for research in social media are provided.

    Oakley, Marnie; Spallek, Heiko

    2012-03-01

    Social media are part of the fabric of today's world, from which health care is not excluded. Based on its distribution capacity, a single individual can cause an amount of damage to an institution that only a few decades ago required access to a mainstream news media outlet. Despite the obvious parallels in professional standards in the medical and dental communities, the scholarly activity and resulting collegial discourse observed among medical professionals remain unmatched in the dental education literature. As a result, a rigorous research agenda on the topic is indicated. Once these results are evaluated and thoroughly vetted, actions should be tailored to address the needs, minimize the threats, and maximize the opportunities that have been already noted by the medical profession. Regardless of input, albeit internal or external, a cadre of individuals who are willing to develop philosophy, policy, and procedure related to the use of social media policies in dental education can then be identified to evaluate the issues unique to the institution and perhaps the profession.

    In their contribution, Remschmidt and colleagues (1) put forward an innovative approach for recruiting female, German study participants from diverse social and ethnical backgrounds to assess their knowledge, attitudes, and behaviors regarding HPV vaccination. The approach involves placing advertisements on the social media platform Facebook that specify tags for not only the sought after socio-demographic characteristics (age, gender) but also self-relevant aspects of the target group. These tags determine which Facebook users will see the ad. By sequentially adjusting the tags, the researchers were able to recruit different sub-populations, resulting in a final sample similar to a representative German sample for a particular age group.

    2010-07-01

    Full Text Available This paper reports on a case study in which the course coordinator attempted to introduce research into the first year media arts curriculum in an effort to engage students through an enquiry learning approach. The findings from student evaluations conducted over a five year period reveal the challenges as well as the benefits to learners. The increase in student mean scores for evaluation criteria together with student qualitative comments in response to evaluations conducted following redesign of the curriculum, suggest that practice-based research, particularly when connected to “real world” issues, can be an effective strategy for re-engaging the first-year learner through the creative problem-solving process. The paper concludes with a discussion of the implications of the findings from these trials as well as suggestions for further research.

    The degradation and mineralization of aspartame (ASP) in aqueous solution were investigated, for the first time, by electrochemical advanced oxidation processes (EAOPs) in which hydroxyl radicals were formed concomitantly in the bulk from Fenton reaction via in situ electrogenerated Fenton's reagent and at the anode surface from the water oxidation. Experiments were performed in an undivided cylindrical glass cell with a carbon-felt cathode and a Pt or boron-doped diamond (BDD) anode. The effect of Fe(2+) concentration and applied current on the degradation and mineralization kinetics of ASP was evaluated. The absolute rate constant for the reaction between ASP and OH was determined as (5.23 ± 0.02) × 10(9) M(-1) s(-1) by using the competition kinetic method. Almost complete mineralization of ASP was achieved with BDD anode at 200 mA constant current electrolysis. The formation and generation of the formed carboxylic acids (as ultimate end products before complete mineralization) and released inorganic ion were monitored by ion-exclusion high performance liquid chromatography (HPLC) and ion chromatography techniques, respectively. The global toxicity of the treated ASP solution during treatment was assessed by the Microtox(®) method using V. fischeri bacteria luminescence inhibition.

  14. How the mass media report social statistics: a case study concerning research on end-of-life decisions.

    Seale, Clive

    2010-09-01

    The issue of whether it is right to be concerned about the accuracy with which mass media report social scientific research is explored through a detailed case study of media reporting of two surveys of UK doctors' end-of-life decision-making. Data include press releases, emails and field notes taken during periods of media interest supplemented by a collection of print and broadcast media reports. The case study contributes to existing knowledge about the ways in which mass media establish, exaggerate and otherwise distort the meaning of statistical findings. Journalists ignored findings that did not fit into existing media interest in the 'assisted dying' story and were subject to pressure from interest groups concerned to promote their own interpretations and viewpoints. Rogue statistics mutated as they were set loose from their original research report context and were 'laundered' as they passed from one media report to another. Yet media accounts of the research, fuelling an already heated public debate about ethical issues in end-of-life care, arguably acted as a conduit for introducing new considerations into this debate, such as the role played by sedation at the end of life, the extent to which euthanasia is practiced outside the law, and the extent of medical opposition to the legalisation of assisted dying. The expectation that accuracy and comprehensiveness should be the sole criteria for judging journalists' reports is, finally, considered to be unrealistic and it is argued that social scientists need to understand and adapted to the conditions under which mass media reporting operates if they are to succeed in introducing the findings of social research into public debates.

    Fifty-five facilities that consumed substantial amounts of electricity, natural gas, or fuel oil were surveyed by telephone in 1983. The primary objective of the survey was to estimate the potential electricity that could be generated in the SCE service territory using cogeneration technology. An estimated 3667 MW sub e could potentially be generated using cogenerated technology. Of this total, current technology could provide 2569 MW sub p and advanced technology could provide 1098 MW sub e. Approximately 1611 MW sub t was considered not feasible to produce electricity with either current or advanced cogeneration technology.

    The Massachusetts Childhood Obesity Research Demonstration Study (MA-CORD) was a multi-level, multi-sector community intervention with a media competition component to provide an overarching synergy and promote awareness of target behaviors to reduce childhood obesity. Students participating in the media competition were tasked with developing videos, song/rap lyrics, and artwork that reflected the goals. The aim of this study is to document the process used to develop and implement the media competition along with its reach and adoption. An adapted version of Neta and colleagues' 2015 framework on dissemination and implementation was used to summarize the process by which the media competition was developed and implemented. Adoption was defined by whether eligible schools or afterschool programs decided to implement the media competition. Reach was defined by student participation rates within schools/programs and the number of votes cast for the finalists on the coalition website and students' paper ballots. A total of 595 students participated in the media competition from 18 school and afterschool programs in two communities. Adoption of the media competitions ranged from 22% to 100% in programs and reach ranged from 3% to 33% of the student population. The documentation of the implementation should contribute to the replication of the media competition.

    The global growth and development of social media has had a positive impact on many individuals who use augmentative and alternative communication (AAC), who use it to communicate and connect with others. Research evidence into the use of social media by adults with acquired conditions who use AAC is limited. These individuals are a heterogeneous population, who can present with a range of linguistic, cognitive and physical needs, some of which progress rapidly, making accessing social media a challenge. These issues warrant research focusing on developing interventions to support the use of social media and the impact of these interventions. For individuals with acquired conditions who have previously used social media and for those who are new to the experience, social media can offer a vital connection to friends, family and health professionals. This paper examines current gaps in knowledge in this area in the field of AAC and proposes potential methodologies for future research. These include combining qualitative and quantitative methodologies (e.g., analysis of online interactions and observational data) that would be useful tools for data collection in an under-researched field.

    The Experimental Advanced Airborne Research Lidar (EAARL) is an example of a Light Detection and Ranging (Lidar) system that utilizes a blue-green wavelength (532 nanometers) to determine the distance to an object. The distance is determined by recording the travel time of a transmitted pulse at the speed of light (fig. 1). This system uses raster laser scanning with full-waveform (multi-peak) resolving capabilities to measure submerged topography and adjacent coastal land elevations simultaneously (Nayegandhi and others, 2009). This document reviews procedures for the post-processing of EAARL data using the custom-built Airborne Lidar Processing System (ALPS). ALPS software was developed in an open-source programming environment operated on a Linux platform. It has the ability to combine the laser return backscatter digitized at 1-nanosecond intervals with aircraft positioning information. This solution enables the exploration and processing of the EAARL data in an interactive or batch mode. ALPS also includes modules for the creation of bare earth, canopy-top, and submerged topography Digital Elevation Models (DEMs). The EAARL system uses an Earth-centered coordinate and reference system that removes the necessity to reference submerged topography data relative to water level or tide gages (Nayegandhi and others, 2006). The EAARL system can be mounted in an array of small twin-engine aircraft that operate at 300 meters above ground level (AGL) at a speed of 60 meters per second (117 knots). While other systems strive to maximize operational depth limits, EAARL has a narrow transmit beam and receiver field of view (1.5 to 2 milliradians), which improves the depth-measurement accuracy in shallow, clear water but limits the maximum depth to about 1.5 Secchi disk depth (~20 meters) in clear water. The laser transmitter [Continuum EPO-5000 yttrium aluminum garnet (YAG)] produces up to 5,000 short-duration (1.2 nanosecond), low-power (70 microjoules) pulses each second

    Full Text Available In the few years since the advent of ‘Big Data’ research, social media analytics has begun to accumulate studies drawing on social media as a resource and tool for research work. Yet, there has been relatively little attention paid to the development of methodologies for handling this kind of data. The few works that exist in this area often reflect upon the implications of ‘grand’ social science methodological concepts for new social media research (i.e. they focus on general issues such as sampling, data validity, ethics, etc.. By contrast, we advance an abductively oriented methodological suite designed to explore the construction of phenomena played out through social media. To do this, we use a software tool – Chorus – to illustrate a visual analytic approach to data. Informed by visual analytic principles, we posit a two-by-two methodological model of social media analytics, combining two data collection strategies with two analytic modes. We go on to demonstrate each of these four approaches ‘in action’, to help clarify how and why they might be used to address various research questions.

    Youth bear a significant proportion of the sexually transmitted infection (STI)/HIV burden in the United States, CDC, 2010. Available at: http://www.cdc.gov/std/stats09/default.htm, with rates of some STIs increasing among youth of color and young men who have sex with men. Technology use among youth also continues to increase. The ubiquitous nature of technology use among youth offers a multitude of opportunities to promote youth sexual health and to prevent disease transmission and unplanned pregnancies. To date, there have been a handful of peer-reviewed articles published regarding the feasibility, acceptability, and effectiveness of using new media and technology for sexual health promotion. Despite recent publications, there is still a real need for high-quality research to understand the impact of different forms of new media use on youth sexual health, as well as to determine the best ways to harness technology to promote safer sex behaviors, both for the short- and long-term. In March 2011, Internet Sexuality Information Services (ISIS), National Institute of Mental Health (NIMH), and the Ford Foundation convened a meeting of scientists and technology experts to discuss how to effectively conduct sexual health promotion research using new forms of technology. The meeting was structured to cover the following topic areas: (i) research-community partnerships, (ii) institutional review board and ethical issues, (iii) theoretical frameworks, (iv) intervention approaches, (v) recruitment methods, and (vi) assessing impact. Presentations included case studies of successful technology-based HIV/STI prevention interventions for youth, which led to broader discussions on how to conduct research in this area. This article summarizes the meeting proceedings, highlights key points, offers recommendations, and outlines future directions.

    In recent years, there has been an increased interest in the use of polarization effects for radar and electromagnetic imaging problems (References 1, 2, and 3). The problem of electro­ magnetic imaging can be divided into the following areas: (1) Propagation of the Stokes' vector from the transmitter to the target region through various atmospheric conditions (rain, dust, fog, clouds, turbulence, etc.). (2) Scattering of the Stokes' vector from the object. (3) Scattering of the Stokes' vector from the rough surface, terrain, and the volume scattering. (4) Propagation of the Stokes' vector from the target region to the receiver. (5) The characteristics of the receiver relating the Stokes' vector to the output. The propagation characteristics of the Stokes' vector through various media can be described by the equation of transfer. Even though the scalar equation of transfer has been studied extensively in the past, the vector equation of transfer has not received as much attention. In recent years, however, a...

    Funding for radioecology in Europe escalated after the Chernobyl accident, and remained elevated for some 15 year. The enhanced funding permitted Europeans to explore new directions in radioecology, particularly in the area of effects to non-human biota. Herein we highlight several recent advances: (1) an attempt to merge environmental risk analysis methods for radioactive contamination with those for other pollutants using species sensitivity distribution; (2) attempts to extrapolate damage observed in individual organisms to potential effects in their populations; and (3) the use of advanced models to estimate and explain changes in an individual's energy allocation as a result of exposure to low doses of radionuclides. We conclude by presenting the radioecology Alliance: an international network whose goal is to integrate resources in order to efficiently fill knowledge gaps in radioecology and improve risk assessments tools that support both human and environmental radioprotection.

Media rhetoric research embarks on studying that puts research objects into a dynamic system that is undergoing communication. Nowadays, there has not been a media of omnipotence; namely interacting comprehensively with human's sense organ of hearing, vision, smelling, dermal sensation etc. Rather at most can act simultaneously on people's vision and hearing. Therefore, it is of necessity to deem handling the limit of media rhetoric research as the primacy, thereafter to consider the way to express concisely and vividly. In reference to media rhetoric method research, it is also in need to have an in depth research on the influence of audience attitude and their acts upon media. Key words: media rhetoric; information transfer; methodology

    Full Text Available Background: The purpose of this study was to investigate social media technology trendsin Nielsen – a global information and measurement company – and to establish how thesetechnologies can help the company to create a knowledge-sharing culture.Objective: The objective of this study was to investigate trends in knowledge-sharingtechnologies in Nielsen.Method: The researchers distributed semi-structured questionnaires to a sample of employeesin Nielsen’s Television Audience Measurement Department. They also conducted interviewswith 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 knowledgesharingculture at Nielsen. The researchers validated the data to see whether it could supportthe research and used triangulation to create a holistic view of the data they received from thequestionnaires.Results: The findings of the study revealed that respondents had a positive attitude to sharingknowledge with one another through using social media tools. However, some respondentsthought that technology, in general, was ‘the tree of good and evil’. The survey findingsshowed that Nielsen did have social media tools. However, not all employees were awareof these tools or were willing to use the tools to share knowledge. This study highlighted thepossible advantages of the social media for sharing knowledge and how Nielsen could use thetools more widely.Conclusion: In order for a knowledge sharing culture to thrive at Nielsen, its employees needto engage more with social media tools in their business practices.

  18. USE OF SOCIAL MEDIA IN IT PROJECT MANAGEMENT: A LITERATURE REVIEW BASED ON HERMENEUTICS AND A RESEARCH AGENDA

    Full Text Available Since IT projects have been the key to success in today’s competitive environment, the adoption of most appropriate tools for managing these projects is essential. Social media, such as wikis, blogs and microblogs, have emerged to facilitate knowledge management in new ways, and subsequently contribute to project success. However, companies underexplore these tools as support in project management. Some of the challenges faced by project managers are organizational culture, lack of familiarity with the tools and with data storage solutions. The objective of this paper is twofold: 1. Analyze the use of social media in project management, specifically in IT projects; and 2. Provide a research agenda for the use of social media in project management. This is an exploratory qualitative study based on hermeneutic approach. The literature review is based on academic papers published in the last 10 years and searchable by Google Scholar. The literature review shows that despite the potential of social media in project management, most of the empirical evidence presented in the literature so far involves adoption of a single tool or separate tools. The research agenda provides guidance for further research on the application of social media in IT project management (ITPM. This paper contributes to practice by offering project managers a broad view of how social media are being used and how they can be adopted in ITPM in the coming years.

    Clinical research needs to be more useful to patients, clinicians, and other decision makers. To meet this need, more research should focus on patient-centered outcomes, compare viable alternatives, and be responsive to individual patients' preferences, needs, pathobiology, settings, and values. These features, which make comparative effectiveness research (CER) fundamentally patient-centered, challenge researchers to adopt or develop methods that improve the timeliness, relevance, and practical application of clinical studies. In this paper, we describe 10 priority areas that address 3 critical needs for research on patient-centered outcomes (PCOR): (1) developing and testing trustworthy methods to identify and prioritize important questions for research; (2) improving the design, conduct, and analysis of clinical research studies; and (3) linking the process and outcomes of actual practice to priorities for research on patient-centered outcomes. We argue that the National Institutes of Health, through its clinical and translational research program, should accelerate the development and refinement of methods for CER by linking a program of methods research to the broader portfolio of large, prospective clinical and health system studies it supports. Insights generated by this work should be of enormous value to PCORI and to the broad range of organizations that will be funding and implementing CER.

    That there have been remarkable advances in the field of molecular electronic structure during the last decade is clear not only to those working in the field but also to anyone else who has used quantum chemical results to guide their own investiga­ tions. The progress in calculating the electronic structures of molecules has occurred through the truly ingenious theoretical and methodological developments that have made computationally tractable the underlying physics of electron distributions around a collection of nuclei. At the same time there has been consider­ able benefit from the great advances in computer technology. The growing sophistication, declining costs and increasing accessibi­ lity of computers have let theorists apply their methods to prob­ lems in virtually all areas of molecular science. Consequently, each year witnesses calculations on larger molecules than in the year before and calculations with greater accuracy and more com­ plete information on molecular properties. We can surel...
