Mulhearn, Tyler J; Watts, Logan L; Torrence, Brett S; Todd, E Michelle; Turner, Megan R; Connelly, Shane; Mumford, Michael D

2017-01-01

Research misconduct negatively impacts the scientific community and society in general. Providing training in the responsible conduct of research (RCR) to researchers is one viable approach to minimizing research misconduct. Although recent evidence suggests ethics training can indeed be effective, little empirical work has examined the similarities and differences across fields. In the present study, we analyzed 62 empirical studies in engineering, biomedical science, social science, and mixed fields. The findings suggest certain instructional principles, or "golden rules," apply generally to all fields. These golden rules include maintaining a field-specific or field-general approach and emphasizing processes in training. The findings also suggest that content areas contributing to instructional effectiveness vary as a function of field. Generally, it appears that all fields may benefit from taking a multi-pronged approach to ethics education wherein the salient field issues are covered. Implications for RCR education are discussed.

Dunton, K.; Schonberg, S.

2006-12-01

Academic scientists and researchers are increasingly encouraged to develop connections with K-12 educators to promote scientific literacy and bring excitement into the classroom. Such partnerships carry long-term benefits to both teachers and researchers. Teachers gain the tools, confidence, and knowledge to develop research activities with their students that promote scientific inquiry, and researchers benefit from outreach activities that improve communication skills for sharing scientific knowledge with the public. Our K-12 programs have been field based under a theme of Classrooms Without Walls, to take advantage of our local marine environment and a long-term research program on the Alaskan Arctic coast. Our professional development programs for teachers have included the creation of an annual summer graduate level course (Application of Field Research Experiences for K-12 Science and Math Educators) as an introduction to scientific methodology, observation, and inquiry based learning. We provide graduate students as resources in classrooms and for field trip experiences and provide supplies and instrumentation to teachers for K-12 field projects. Finally, teachers have an opportunity to join our researchers to remote sites under various competitive programs that receive federal support (e.g. GK-12, ARMADA). We provide examples of our activities, which are based on recent needs assessment surveys of science teachers; these included development of content knowledge and providing students with opportunities to connect concepts with experiences. Our goal is to provide field experiences to teachers and students that enable them to relate science concepts to the real world.

Roeder, L.; Jundt, R.

2009-12-01

Sponsored by the Department of Energy, the ARM Climate Research Facility is a global scientific user facility for the study of climate change. To publicize progress and achievements and to reach new users, the ACRF uses a variety of Web 2.0 tools and strategies that build off of the program’s comprehensive and well established News Center (www.arm.gov/news). These strategies include: an RSS subscription service for specific news categories; an email “newsletter” distribution to the user community that compiles the latest News Center updates into a short summary with links; and a Facebook page that pulls information from the News Center and links to relevant information in other online venues, including those of our collaborators. The ACRF also interacts with users through field campaign blogs, like Discovery Channel’s EarthLive, to share research experiences from the field. Increasingly, field campaign Wikis are established to help ACRF researchers collaborate during the planning and implementation phases of their field studies and include easy to use logs and image libraries to help record the campaigns. This vital reference information is used in developing outreach material that is shared in highlights, news, and Facebook. Other Web 2.0 tools that ACRF uses include Google Maps to help users visualize facility locations and aircraft flight patterns. Easy-to-use comment boxes are also available on many of the data-related web pages on www.arm.gov to encourage feedback. To provide additional opportunities for increased interaction with the public and user community, future Web 2.0 plans under consideration for ACRF include: evaluating field campaigns for Twitter and microblogging opportunities, adding public discussion forums to research highlight web pages, moving existing photos into albums on FlickR or Facebook, and building online video archives through YouTube.

2016-11-16

Protein crystallization under a magnetic field is an interesting research topic because a magnetic field may provide a special environment to acquire improved quality protein crystals. Because high-quality protein crystals are very useful in high-resolution structure determination using diffraction techniques (X-ray, neutron, and electron diffraction), research using magnetic fields in protein crystallization has attracted substantial interest; some studies have been performed in the past two decades. In this research field, the hardware is especially essential for successful studies because the environment is special and the design and utilization of the research apparatus in such an environment requires special considerations related to the magnetic field. This paper reviews the hardware for protein crystallization (including the magnet systems and the apparatus designed for use in a magnetic field) and progress in this area. Future prospects in this field will also be discussed.

How can we improve clinical research in pneumonia?

PubMed

Ramirez, Julio A

2018-05-01

The primary challenges in the field of clinical research include a lack of support within existing infrastructure, insufficient number of clinical research training programs and a paucity of qualified mentors. Most medical centers offer infrastructure support for investigators working with industry sponsors or government-funded clinical trials, yet there are a significant amount of clinical studies performed in the field of pneumonia which are observational studies. For this type of research, which is frequently unfunded, support is usually lacking. In an attempt to optimize clinical research in pneumonia, at the University of Louisville, we developed a clinical research coordinating center (CRCC). The center manages clinical studies in the field of respiratory infections, with the primary focus being pneumonia. Other activities of the CRCC include the organization of an annual clinical research training course for physicians and other healthcare workers, and the facilitation of international research mentoring by a process of connecting new pneumonia investigators with established clinical investigators. To improve clinical research in pneumonia, institutions need to have the appropriate infrastructure in place to support investigators in all aspects of the clinical research process.

Proctor, Enola K; Chambers, David A

2017-09-01

We report outcomes of an NIH-convened meeting on training for dissemination and implementation (D&I) research, focused on accelerating translation of research to healthcare practice. Participants included leaders of current trainings, center directors, and those trained in existing programs. Given the large proportion of D&I research focused on cancer control, mental health, and substance abuse, participants overwhelmingly reflected the experiences and challenges of gaining capacity in behavioral health-related D&I research. The 2-day meeting required participants to draw upon their experiences to help build a field-wide perspective for D&I research training, identify resources needed to support this perspective, and brainstorm gaps in training that needed to be filled. Questions were sent to participants in advance, and responses were synthesized and presented to discuss during the meeting. A preliminary "field-wide" perspective emerged, spanning multiple disciplines, training models, and career levels. Current programs face high demand, need for continued evolution to reflect field advances, and sustainability challenges. Current gaps include implementation practice and predoctoral training. Federal funding is key to D&I research training, be it through grants or agency-led training programs, in order to span and address specialized disease and disorder foci and career tracks.

Improving scientific literacy is a goal in the United States. Scientists from the United States are often expected to present research findings in ways that are meaningful and accessible to the general public, including K-12 students. PolarTREC - Teachers and Researchers Exploring and Collaborating, a program funded by the National Science Foundation, partners teachers with scientists in the Arctic and Antarctica. Teachers communicate the research to general audiences on a regular basis. After the field experience, they then create classroom-ready lessons to relay the science exploration into science curriculum. In this presentation, secondary level educators, will share their experiences with being part of field research teams in the Arctic and Antarctica, and their strategies for bringing current science research into the classroom and aligning lessons with Next Generation Science Standards (NGSS). Topics include an overview on using polar science to teach about climate change, application of field research techniques to improve students' understanding of scientific investigation methodology, phenology observations, soil porosity and permeability, litter decomposition, effect of sunlight on release of carbon dioxide from thawing permafrost, and understanding early life on Earth by studying stromatolites in Antarctica.

PubMed

Wallen, M; Pandit, A

2009-05-01

In addressing the task of developing an undergraduate module in the field of tissue engineering, the greatest challenge lies in managing to capture what is a growing and rapidly changing field. Acknowledging the call for the development of greater critical thinking and interpersonal skills among the next generation of engineers as well as encouraging students to engage actively with the dynamic nature of research in the field, the module was developed to include both project-based and cooperative-learning experiences. These learning activities include developing hypotheses for the application of newly introduced laboratory procedures, a collaborative mock grant submission, and debates on ethical issues in which students are assigned roles as various stakeholders. Feedback from module evaluations has indicated that, while students find the expectations challenging, they are able to gain an advanced insight into a dynamic field. More importantly, students develop research competencies by engaging in activities that require them to link current research directions with their own development of hypotheses for future tissue-engineering applications.

2015-04-01

Several studies have demonstrated that undergraduate students benefit from research experiences. Benefits of undergraduate research include 1) personal and intellectual development, 2) more and closer contact with faculty, 3) the use of active learning techniques, 4) creation of high expectations, 5) development of creative and problem-solving skills, 6) greater independence and intrinsic motivation to learn, and 7) exposure to practical skills. The scientific discipline also benefits, as studies have shown that undergraduates who engage in research experiences are more likely to remain science majors and finish their degree program (Lopatto, 2007). Research experiences come as close as possible to allowing undergraduates to experience what it is like to be an academic or research member of their profession working to advance their discipline. Soils form in the field, therefore, field experiences are very important in developing a complete and holistic understanding of soil science. Combining undergraduate research with field experiences can provide extremely beneficial outcomes to the undergraduate student, including increased understanding of and appreciation for detailed descriptions and data analysis as well as an enhanced ability to see how various parts of their undergraduate education come together to understand a complex problem. The experiences of the authors in working with undergraduate students on field-based research projects will be discussed, along with examples of some of the undergraduate research projects that have been undertaken. In addition, student impressions of their research experiences will be presented. Reference Lopatto, D. 2007. Undergraduate research experiences support science career decisions and active learning.

McGarty, Arlene M; Penpraze, Victoria; Melville, Craig A

2014-05-01

Many methodological questions and issues surround the use of accelerometers as a measure of physical activity during field-based research. To ensure overall research quality and the accuracy of results, methodological decisions should be based on study research questions. This paper aims to systematically review accelerometer use during field-based research in children and adolescents with intellectual disabilities. Medline, Embase, Cochrane Library, Web of Knowledge, PsycINFO, PubMed, and a thesis database (up to May 2013) were searched to identify relevant articles. Articles which used accelerometry-based monitors, quantified activity levels, and included ambulatory children and adolescents (≤ 18 years) with intellectual disabilities were included. Based on best practice guidelines, a form was developed to extract data based on 17 research components of accelerometer use. The search identified 429 articles. Ten full-text articles met the criteria and were included in the review. Many shortcomings in accelerometer use were identified, with the percentage of review criteria met ranging from 12% to 47%. Various methods of accelerometer use were reported, with most use decisions not based on population-specific research. However, a lack of measurement research, e.g., calibration/validation, for children and adolescents with intellectual disabilities is limiting the ability of field-based researchers to make to the most appropriate accelerometer use decisions. The methods of accelerometer use employed can have significant effects on the quality and validity of results produced, which researchers should be more aware of. To allow informed use decisions, there should be a greater focus on measurement research related to children and adolescents with intellectual disabilities. Copyright © 2014 Elsevier Ltd.

Concern that "EMF" magnetic fields from power lines cause cancer.

PubMed

Repacholi, Michael

2012-06-01

In 2002, the International Agency for Research on Cancer (IARC, 2002) categorized extremely low frequency (ELF) (including the power frequencies of 50 and 60 Hz) magnetic fields as "possibly carcinogenic to humans." That was based on pooled analyses of epidemiological research that reported an association between exposure to low-level magnetic fields and childhood leukemia. In 2007 a task group of scientific experts convened by the World Health Organization (WHO) acknowledged the IARC categorization but found that the laboratory studies and other research results did not support the association. Taking all evidence into account WHO reported that it could not confirm the existence of any health consequences from exposure to low-level magnetic fields. There remains continuing concern by some people that exposure to power frequency magnetic fields may cause adverse health effects, particularly childhood leukemia. Public health authorities need to fully understand the reasons for that ongoing concern and effective ways to address it. This paper describes what drives the concern, including how people perceive risks, how WHO and other public health authorities assess scientific research to determine whether health risks exist and the conclusions they have reached about power frequency magnetic fields. This paper also addresses the scientific basis of international exposure guidelines for power frequency magnetic fields and what precautionary measures are warranted to address the concern.

Geomorphology in context: Dispatches from the field

NASA Astrophysics Data System (ADS)

Harden, Carol P.

2013-10-01

Field research enables a researcher to view geomorphic systems in broader contexts than those envisioned while at a desk and can yield unanticipated insights that change the course of an investigation or affect the interpretation of results. Geomorphological field research often produces 'aha!' moments, epiphanies that enhance understanding and lead toward more complete explanation of the processes and landforms under study. This paper uses examples from 'aha!' moments in the field to demonstrate the importance of field observation as a way of gaining information about the broader contexts of research sites, especially in process geomorphology. Spatial contexts include the scales of processes and features, linkages between a study site and its surroundings, and information observed in the field about other processes, anthropogenic activities, or unexpected factors that might affect a study. Temporal contexts, not as evident in the field, place a research site in a longer term history of changes and adjustments. Finally, exploring an abstract set of mental contexts reveals reasons that expectations differ from the realities encountered in the field—constraints and biases that a researcher may not have noted—and the possibility that the unexpected can potentially advance geomorphic research. Time spent in the field complements scientific reductionism and provides opportunities to appreciate the richness and complexity of Earth surface systems.

In his perspective "Navigating between stealth advocacy and unconscious dogmatism: the challenge of researching the norms, politics and power of global health," Ooms argues that actions taken in the field of global health are dependent not only on available resources, but on the normative premise that guides how these resources are spent. This comment sets out how the application of a predominately biomedical positivist research tradition in global health, has potentially limited understanding of the value judgements underlying decisions in the field. To redress this critical social science, including health policy analysis has much to offer, to the field of global health including on questions of governance. PMID:27239873

The article focuses on the qualitative research approach in human and social sciences, analyzing its status in comparison to the other traditions vying for hegemony in the public health field, conjugating the dialogue with the literature, especially the propositions pertaining to the social fields present in the work of Pierre Bourdieu, with elements concerning the field's dynamics, including some empirical data. Challenges identified in the article include hurdles to interdisciplinary dialogue and equity in the production of knowledge, based on recognition of the founding place of human and social sciences in the public health field. The article discusses strategies to reshape the current correlation of forces among centers of knowledge in public health, especially those capable of impacting the committees and agendas that define the accumulation of symbolic and economic capital in the field.

Influencing attitudes toward science through field experiences in biology

NASA Astrophysics Data System (ADS)

Carpenter, Deborah Mcintyre

The purpose of this study was to determine how student attitudes toward science are influenced by field experiences in undergraduate biology courses. The study was conducted using two institutions of higher education including a 2-year lower-level and a 2-year upper-level institution. Data were collected through interviews with student participants, focus group discussions, students' journal entries, and field notes recorded by the researcher during the field activities. Photographs and video recordings were also used as documentation sources. Data were collected over a period of 34 weeks. Themes that emerged from the qualitative data included students' beliefs that field experiences (a) positively influence student motivation to learn, (b) increase student ability to learn the concepts being taught, and (c) provide opportunities for building relationships and for personal growth. The findings of the study reinforce the importance of offering field-study programs at the undergraduate level to allow undergraduate students the opportunity to experience science activities in a field setting. The research study was framed by the behavioral and developmental theories of attitude and experience including the Theory of Planned Behavior (Ajzen, 1991) and the Theory of Experiential Learning (Kolb, 1984).

Retail food environments research in Canada: A scoping review.

PubMed

Minaker, Leia M; Shuh, Alanna; Olstad, Dana L; Engler-Stringer, Rachel; Black, Jennifer L; Mah, Catherine L

2016-06-09

The field of retail food environments research is relatively new in Canada. The objective of this scoping review is to provide an overview of retail food environments research conducted before July 2015 in Canada. Specifically, this review describes research foci and key findings, identifies knowledge gaps and suggests future directions for research. A search of published literature concerning Canadian investigations of retail food environment settings (food stores, restaurants) was conducted in July 2015 using PubMed, Web of Science, Scopus, PsychInfo and ERIC. Studies published in English that reported qualitative or quantitative data on any aspect of the retail food environment were included, as were conceptual papers and commentaries. Eighty-eight studies were included in this review and suggest that the field of retail food environments research is rapidly expanding in Canada. While only 1 paper was published before 2005, 66 papers were published between 2010 and 2015. Canadian food environments research typically assessed either the socio-economic patterning of food environments (n = 28) or associations between retail food environments and diet, anthropometric or health outcomes (n = 33). Other papers profiled methodological research, qualitative studies, intervention research and critical commentaries (n = 27). Key gaps in the current literature include measurement inconsistency among studies and a lack of longitudinal and intervention studies. Retail food environments are a growing topic of research, policy and program development in Canada. Consistent methods (where appropriate), longitudinal and intervention research, and close partnerships between researchers and key stakeholders would greatly advance the field of retail food environments research in Canada.

Cannon, Joanna E; Guardino, Caroline; Antia, Shirin D; Luckner, John L

2016-01-01

The field of education of deaf and hard of hearing (DHH) students has a paucity of evidence-based practices (EBPs) to guide instruction. The authors discussed how the research methodology of single-case design (SCD) can be used to build EBPs through direct and systematic replication of studies. An overview of SCD research methods is presented, including an explanation of how internal and external validity issues are addressed, and why SCD is appropriate for intervention research with DHH children. The authors then examine the SCD research in the field according to quality indicators (QIs; at the individual level and as a body of evidence) to determine the existing evidence base. Finally, future replication areas are recommended to fill the gaps in SCD research with students who are DHH in order to add to the evidence base in the field.

Typically authentic research activities are separated from rigorous classroom teaching. Here we assessed the potential of integrating teaching and research activities both in the field and in the laboratory. We worked with students from both US and abroad without strong science background to utilize advanced environmental sensors and statistical tool to conduct innovative projects. The students include one from Namibia and two local high school students in Indianapolis (through Project SEED, Summer Experience for the Economically Disadvantaged). They conducted leaf potential measurements, isotope measurements and meta-analysis. The experience showed us the great potential of integrating teaching and research in both field and laboratory settings.

Interdisciplinary research and education in the Vienna Doctoral Programme on Water Resource Systems: a framework for evaluation

NASA Astrophysics Data System (ADS)

Bloeschl, G.; Carr, G.; Loucks, D. P.

2017-12-01

Greater understanding of how interdisciplinary research and education evolves is critical for identifying and implementing appropriate programme management strategies. We propose a program evaluation framework that is based on social learning processes (individual learning, interdisciplinary research practices, and interaction between researchers with different backgrounds); social capital outcomes (ability to interact, interpersonal connectivity, and shared understanding); and knowledge and human capital outcomes (new knowledge that integrates multiple research fields). The framework is tested on established case study doctoral program: the Vienna Doctoral Program on Water Resource Systems. Data are collected via mixed qualitative/quantitative methods that include semi-structured interviews, publication co-author analysis, analysis of research proposals, categorisation of the interdisciplinarity of publications and graduate analysis. Through the evaluation and analysis, several interesting findings about how interdisciplinary research evolves and can be supported are identified. Firstly, different aspects of individual learning seem to contribute to a researcher's ability to interact with researchers from other research fields and work collaboratively. These include learning new material from different research fields, learning how to learn new material and learning how to integrate different material. Secondly, shared interdisciplinary research practices can be identified that may be common to other programs and support interaction and shared understanding between different researchers. They include clarification and questioning, harnessing differences and setting defensible research boundaries. Thirdly, intensive interaction between researchers from different backgrounds support connectivity between the researchers, further enabling cross-disciplinary collaborative work. The case study data suggest that social learning processes and social capital outcomes precede new interdisciplinary research findings and are therefore a critical aspect to consider in interdisciplinary program management.

Evaluating co-creation of knowledge: from quality criteria and indicators to methods

NASA Astrophysics Data System (ADS)

Schuck-Zöller, Susanne; Cortekar, Jörg; Jacob, Daniela

2017-11-01

Basic research in the natural sciences rests on a long tradition of evaluation. However, since the San Francisco Declaration on Research Assessment (DORA) came out in 2012, there has been intense discussion in the natural sciences, above all amongst researchers and funding agencies in the different fields of applied research and scientific service. This discussion was intensified when climate services and other fields, used to make users participate in research and development activities (co-creation), demanded new evaluation methods appropriate to this new research mode. This paper starts by describing a comprehensive and interdisciplinary literature overview of indicators to evaluate co-creation of knowledge, including the different fields of integrated knowledge production. Then the authors harmonize the different elements of evaluation from literature in an evaluation cascade that scales down from very general evaluation dimensions to tangible assessment methods. They describe evaluation indicators already being documented and include a mixture of different assessment methods for two exemplary criteria. It is shown what can be deduced from already existing methodology for climate services and envisaged how climate services can further to develop their specific evaluation method.

Hanefeld, Johanna

2016-02-06

In his perspective "Navigating between stealth advocacy and unconscious dogmatism: the challenge of researching the norms, politics and power of global health," Ooms argues that actions taken in the field of global health are dependent not only on available resources, but on the normative premise that guides how these resources are spent. This comment sets out how the application of a predominately biomedical positivist research tradition in global health, has potentially limited understanding of the value judgements underlying decisions in the field. To redress this critical social science, including health policy analysis has much to offer, to the field of global health including on questions of governance. © 2016 by Kerman University of Medical Sciences.

I will discuss my experience co-ordinating a range of communication activities for a multi-university research programme called Methane in the Arctic: Measurements and Modelling. The project included ground- and aircraft-based fieldwork in the European Arctic, as well as computer modelling. Our communication activities included: our own field blog (www.arcticmethane.wordpress.com), which was syndicated to the Scientific American Expeditions blog; writing articles for other blogs with a wider audience than our own; use of twitter; and podcasting our field work. The grand finale to our communications work was a live event at a science festival, in which we took the audience along with us on a recreated research flight, complete with a life-size mock up of a section of our research aircraft. I will discuss my experiences of these forms of communication, and give an evaluation of their successes and failures.

Biofabrication is an evolving research field that has recently received significant attention. In particular, the adoption of Biofabrication concepts within the field of Tissue Engineering and Regenerative Medicine has grown tremendously, and has been accompanied by a growing inconsistency in terminology. This article aims at clarifying the position of Biofabrication as a research field with a special focus on its relation to and application for Tissue Engineering and Regenerative Medicine. Within this context, we propose a refined working definition of Biofabrication, including Bioprinting and Bioassembly as complementary strategies within Biofabrication.

Dielectrophoresis for Biomedical Sciences Applications: A Review

PubMed Central

Abd Rahman, Nurhaslina; Ibrahim, Fatimah; Yafouz, Bashar

2017-01-01

Dielectrophoresis (DEP) is a label-free, accurate, fast, low-cost diagnostic technique that uses the principles of polarization and the motion of bioparticles in applied electric fields. This technique has been proven to be beneficial in various fields, including environmental research, polymer research, biosensors, microfluidics, medicine and diagnostics. Biomedical science research is one of the major research areas that could potentially benefit from DEP technology for diverse applications. Nevertheless, many medical science research investigations have yet to benefit from the possibilities offered by DEP. This paper critically reviews the fundamentals, recent progress, current challenges, future directions and potential applications of research investigations in the medical sciences utilizing DEP technique. This review will also act as a guide and reference for medical researchers and scientists to explore and utilize the DEP technique in their research fields. PMID:28245552

Never the twain shall meet? - a comparison of implementation science and policy implementation research

PubMed Central

2013-01-01

Background Many of society’s health problems require research-based knowledge acted on by healthcare practitioners together with implementation of political measures from governmental agencies. However, there has been limited knowledge exchange between implementation science and policy implementation research, which has been conducted since the early 1970s. Based on a narrative review of selective literature on implementation science and policy implementation research, the aim of this paper is to describe the characteristics of policy implementation research, analyze key similarities and differences between this field and implementation science, and discuss how knowledge assembled in policy implementation research could inform implementation science. Discussion Following a brief overview of policy implementation research, several aspects of the two fields were described and compared: the purpose and origins of the research; the characteristics of the research; the development and use of theory; determinants of change (independent variables); and the impact of implementation (dependent variables). The comparative analysis showed that there are many similarities between the two fields, yet there are also profound differences. Still, important learning may be derived from several aspects of policy implementation research, including issues related to the influence of the context of implementation and the values and norms of the implementers (the healthcare practitioners) on implementation processes. Relevant research on various associated policy topics, including The Advocacy Coalition Framework, Governance Theory, and Institutional Theory, may also contribute to improved understanding of the difficulties of implementing evidence in healthcare. Implementation science is at a relatively early stage of development, and advancement of the field would benefit from accounting for knowledge beyond the parameters of the immediate implementation science literature. Summary There are many common issues in policy implementation research and implementation science. Research in both fields deals with the challenges of translating intentions into desired changes. Important learning may be derived from several aspects of policy implementation research. PMID:23758952

Quantized Electromagnetic-Field Propagation in General Non-Local and Non-Stationary Dispersive and Absorbing Media

NASA Astrophysics Data System (ADS)

Jacobs, Verne

Dynamical descriptions for the propagation of quantized electromagnetic fields, in the presence of environmental interactions, are systematically and self-consistently developed in the complimentary Schrödinger and Heisenberg pictures. An open-systems (non-equilibrium) quantum-electrodynamics description is thereby provided for electromagnetic-field propagation in general non-local and non-stationary dispersive and absorbing optical media, including a fundamental microscopic treatment of decoherence and relaxation processes due to environmental collisional and electromagnetic interactions. Particular interest is centered on entangled states and other non-classical states of electromagnetic fields, which may be created by non-linear electromagnetic interactions and detected by the measurement of various electromagnetic-field correlation functions. Accordingly, we present dynamical descriptions based on general forms of electromagnetic-field correlation functions involving both the electric-field and the magnetic-field components of the electromagnetic field, which are treated on an equal footing.

The terahertz (THz) band lies between microwave and infrared rays in wavelength and consists of non-ionizing radiation. Both domestic and foreign research institutions, including the army, have attached considerable importance to the research and development of THz technology because this radiation exhibits both photon-like and electron-like properties, which grant it considerable application value and potential. With the rapid development of THz technology and related applications, studies of the biological effects of THz radiation have become a major focus in the field of life sciences. Research in this field has only just begun, both at home and abroad. In this paper, research progress with respect to THz radiation, including its biological effects, mechanisms and methods of protection, will be reviewed.

Phillips, C. B.; Devore, E. K.

2009-12-01

The SETI Institute hosts a summer Astrobiology Research Experience for Undergraduates program for highly motivated students interested in astrobiology research. Students work with scientists at the SETI Institute and at the nearby NASA Ames Research Center on projects spanning the field of astrobiology from microbiology to planetary geology to astronomy and astrophysics. Each student is mentored by a scientist for his/her summer research project. As astrobiology is interdisciplinary, the first week includes a seminar series to provide a broad foundation in the field as the students begin their research projects. The 10-week program includes a week-long field trip to the SETI Institute’s Allen Telescope Array, located at the Hat Creek Radio Astronomy Observatory in Northern California, as well as a field experience at hydrothermal systems at nearby Lassen Volcanic National Park. Students also participate in local field trips to places like the California Academy of Sciences and other nearby locations of scientific interest, and attend seminars, lectures, and discussions on astrobiology. Students are also invited to attend events at nearby NASA Ames Research Center, which offers the opportunity to interact with other undergraduate and graduate students participating in NASA summer programs. At the end of the program, students write up and present their research projects, and mentors recommend some projects for submission to a national scientific conference, which the selected students will be funded to attend. The Astrobiology REU program emphasizes three main areas, which are listed in the table along with typical project themes. Each year, specific student research projects are described on the website, and students are asked to select the three that most interest them as a part of their applications. Applications are due in early February. Typically, 10 students apply for each available position. Students have been selected from colleges and universities national-wide, including community colleges. The Astrobiology REU program has served 4 classes of students, and is funded through summer of 2011. A total of 61 students have participated (12 in 2006, 17 in 2007, 17 in 2008, and 15 in 2009); all have successfully completed their internships. Of these students, 59% were women, and 21% were minorities. To date 18 students have gone on to graduate studies, in Master’s or PhD programs at schools including Harvard, UC Berkeley, UC Santa Cruz, Stanford, Univ. of Nebraska, and many others, in fields including astronomy, optical science, space life sciences, geology, physics, mechanical engineering, and molecular and cellular biology.

The late 1960s through the 1970s marked an important turning point in the field of gender research, including theory and research in gender development. The establishment of Sex Roles in 1975 as a forum for this research represented an important milestone in the field. In this article, we celebrate the 35th anniversary of Sex Roles and, in particular, its contributions to the field of research on children's and adolescents' gender development. We examine the trends in research on gender development published in Sex Roles since its inception and use this analysis as a vehicle for exploring how the field has grown and evolved over the past few decades. We begin with a brief review of the history of this field of research since 1975. Then, we present a descriptive assessment of articles published on gender development in Sex Roles over time, and link this assessment to general trends that have occurred in the study of gender development over the past 35 years. We conclude with a discussion of future directions for the field of gender development. In particular, we highlight areas in which the journal could play a role in promoting more diversity in topics, methods, and ages employed in gender development research.

Riley, Barbara; Harvey, Jean; Di Ruggiero, Erica; Potvin, Louise

2015-01-01

Population health intervention research (PHIR) is a relatively new research field that studies interventions that can improve health and health equity at a population level. Competencies are one way to give legitimacy and definition to a field. An initial set of PHIR competencies was developed with leadership from a multi-sector group in Canada. This paper describes the development process for these competencies and their possible uses. Methods to develop the competencies included key informant interviews; a targeted review of scientific and gray literature; a 2-round, online adapted Delphi study with a 24-member panel; and a focus group with 9 international PHIR experts. The resulting competencies consist of 25 items grouped into 6 categories. They include principles of good science applicable though not exclusive to PHIR, and more suitable for PHIR teams rather than individuals. This initial set of competencies, released in 2013, may be used to develop graduate student curriculum, recruit trainees and faculty to academic institutions, plan non-degree professional development, and develop job descriptions for PHIR-related research and professional positions. The competencies provide some initial guideposts for the field and will need to be adapted as the PHIR field matures and to meet unique needs of different jurisdictions.

Background Electronic health (eHealth) and mobile health (mHealth) approaches to address low physical activity levels, sedentary behavior, and unhealthy diets have received significant research attention. However, attempts to systematically map the entirety of the research field are lacking. This gap can be filled with a bibliometric study, where publication-specific data such as citations, journals, authors, and keywords are used to provide a systematic overview of a specific field. Such analyses will help researchers better position their work. Objective The objective of this review was to use bibliometric data to provide an overview of the eHealth and mHealth research field related to physical activity, sedentary behavior, and diet. Methods The Web of Science (WoS) Core Collection was searched to retrieve all existing and highly cited (as defined by WoS) physical activity, sedentary behavior, and diet related eHealth and mHealth research papers published in English between January 1, 2000 and December 31, 2016. Retrieved titles were screened for eligibility, using the abstract and full-text where needed. We described publication trends over time, which included journals, authors, and countries of eligible papers, as well as their keywords and subject categories. Citations of eligible papers were compared with those expected based on published data. Additionally, we described highly-cited papers of the field (ie, top ranked 1%). Results The search identified 4805 hits, of which 1712 (including 42 highly-cited papers) were included in the analyses. Publication output increased on an average of 26% per year since 2000, with 49.00% (839/1712) of papers being published between 2014 and 2016. Overall and throughout the years, eHealth and mHealth papers related to physical activity, sedentary behavior, and diet received more citations than expected compared with papers in the same WoS subject categories. The Journal of Medical Internet Research published most papers in the field (9.58%, 164/1712). Most papers originated from high-income countries (96.90%, 1659/1717), in particular the United States (48.83%, 836/1712). Most papers were trials and studied physical activity. Beginning in 2013, research on Generation 2 technologies (eg, smartphones, wearables) sharply increased, while research on Generation 1 (eg, text messages) technologies increased at a reduced pace. Reviews accounted for 20 of the 42 highly-cited papers (n=19 systematic reviews). Social media, smartphone apps, and wearable activity trackers used to encourage physical activity, less sedentary behavior, and/or healthy eating were the focus of 14 highly-cited papers. Conclusions This study highlighted the rapid growth of the eHealth and mHealth physical activity, sedentary behavior, and diet research field, emphasized the sizeable contribution of research from high-income countries, and pointed to the increased research interest in Generation 2 technologies. It is expected that the field will grow and diversify further and that reviews and research on most recent technologies will continue to strongly impact the field. PMID:29669703

2015-04-01

The interdisciplinary postgraduate research and education programme - the Vienna Doctoral Programme on Water Resource Systems - was initiated in 2009. To date, 35 research students, three post-docs and ten faculty members have been engaged in the Programme, from ten research fields (aquatic microbiology, hydrology, hydro-climatology, hydro-geology, mathematical economics, photogrammetry, remote sensing, resource management, structural mechanics, and water quality). The Programme aims to develop research students with the capacity to work across the disciplines, to conduct cutting edge research and foster an international perspective. To do this, a variety of mechanisms are adopted that include research cluster groups, joint study sites, joint supervision, a basic study programme and a research semester abroad. The Programme offers a unique case study to explore if and how these mechanisms lead to research and education outcomes. Outcomes are grouped according to whether they are tangible (publications with co-authors from more than one research field, analysis of graduate profiles and career destinations) or non-tangible (interaction between researchers, networks and trust). A mixed methods approach that includes bibliometric analysis combined with interviews with students is applied. Bibliometric analysis shows that as the Programme has evolved the amount of multi-disciplinary work has increased (32% of the 203 full papers produced by the programme's researchers have authors from more than one research field). Network analysis to explore which research fields collaborate most frequently show that hydrology plays a significant role and has collaborated with seven of the ten research fields. Hydrology researchers seem to interact the most strongly with other research fields as they contribute understanding on water system processes. Network analysis to explore which individuals collaborate shows that much joint work takes place through the five research cluster groups (water resource management, land-surface processes, Hydrological Open Air Laboratory, water and health, modelling and risk). Student interviews highlight that trust between colleagues and supervisors, and the role of spaces for interaction (joint study sites, cluster group meetings, shared offices etc.) are important for joint work. Graduate analysis shows that students develop skills and confidence to work across disciplines through collaborating on their doctoral research. Working collaboratively during the doctorate appears to be strongly correlated with continuing to work in this way after graduation.

Reflections by a student and a faculty member on student-faculty collaborative geophysical field research

NASA Astrophysics Data System (ADS)

Bank, C.; Rotzien, J.

2007-12-01

More and more students and faculty engage in collaborative research. Field geophysics provides a fascinating venue, as it always contributes to interpersonal relations, usually involves off-campus work, and often allows us to meet new people and explore a different culture. Tackling an authentic research problem keeps a faculty member excited about her/his discipline, while allowing a student to engage in the process of science, follow a researcher's thoughts and contribute to a real project. The exchange of ideas and the generation of new knowledge is rewarding to the student as it facilitates her/his academic growth. Despite the obvious advantages of including students in field-based research, few students are allowed such an opportunity because of the institutional commitment in time and money that is necessary for success. Other challenges in field-based geophysical research include steep learning curves related to the use of equipment, unknown outcomes (data that is often difficult to interpret), and a true commitment to the project on the student's part. The faculty member on the other hand faces additional challenges because of the responsibility for students in the field, scheduling constraints, limited funding, and students' diverse academic goals. This presentation will be given by a faculty member and a student who have engaged in various authentic research projects. Projects ranged from afternoon lab exercises on campus (eg, microgravity survey over a tunnel on campus), course projects connected to field trips (eg, magnetic study and subsequent potential field analysis), summer research projects (eg, georadar survey of Deboullie Lake rock glacier), to year-long undergraduate thesis projects (eg, potential field studies at igneous centres of the Navajo Volcanic Field). We will present highlights of these projects, examine their pedagogical merits, and discuss the advantages and rewards we earned as well as the challenges we faced. Despite all challenges, we find that the outcomes, the sense of accomplishment, the rich interpersonal exchange, and the intellectual as well as personal growth of students is well worth the effort that goes into planning and executing such projects. Our aim is to promote collaborative and authentic research, and to find out about creative ways to bring such an experience to a wider range of interested students.

[The need for experiments using primates from a scientific point of view].

Kaup, F J

2007-03-01

Concerning the public discussion on animal experiments using primates, various research fields are demonstrated where non-human primates are necessary for certain scientific reasons at this time. Non-human Primates are used in Germany mainly in regulatory toxicology and pharmaceutical safety studies.A small amount is disposed in different fields of biological or biomedical basic research. This includes in particular neurosciences and infection research. 2006 New and Old World monkeys were needed in Germany in 2005. No chimpanzees are used anymore as laboratory animals in Germany since many years. Several examples are presented to demonstrate that certain research fields need non-human primates as laboratory animals in the foreseeable future.

Field work is one of the aspects of a career in the geosciences that can make it so attractive to students and the public. The chance to go to exciting places, and to see amazing things, while making new discoveries is almost too good to be true. The "Postcards from the Field" capability, developed and implemented in the Windows to the Universe website project in 2006, is now providing a new ability to bring this excitement to a large and global audience online. Windows to the Universe is an extremely popular interdisciplinary Earth and space science educational website, with over 20 million visitors per year, including a large following of students and educators. The website is composed of over 7000 interlinked web pages spanning the geosciences, at three levels of sophistication, in English and Spanish. Our Postcards from the Field capability, which was originally developed in support of a major field campaign in Mexico City in 2006 (the Megacity Initiative: Local and Global Research Observations campaign - MILAGRO), has now been generalized to support submissions from researchers engaged in multiple field campaigns. To date, in addition to postcards submitted during the MILAGRO campaign, we have hosted postcards from researchers and educators studying the life cycle of Adelie penguins in the Antarctic, the East Pacific Rise as a component of the RIDGE2000 program, and storm formation in Europe as a component of the Convective and Orographically- induced Precipitation Study (COPS). We are now expanding our postcard lines to include submissions from researchers engaged in the IPY and educators engaged with the ANDRILL (ANtarctic Geologic DRILLing) Research Immersion for Science Educators program. This presentation will present this new capability, its ease of use, and our vision for how it can be used to bring the excitement of field research to the public, students, and educators online.

A review of human male field studies of hormones and behavioral reproductive effort.

PubMed

Gray, Peter B; McHale, Timothy S; Carré, Justin M

2017-05-01

The purpose of this paper is to review field studies of human male hormones and reproductive behavior. We first discuss life history theory and related conceptual considerations. As illustrations, distinctive features of human male life histories such as coalitional aggression, long-term partnering and paternal care are noted, along with their relevance to overall reproductive effort and developmental plasticity. We address broad questions about what constitutes a human male field study of hormones and behavior, including the kinds of hormone and behavioral measures employed in existing studies. Turning to several sections of empirical review, we present and discuss evidence for links between prenatal and juvenile androgens and sexual attraction and aggression. This includes the proposal that adrenal androgens-DHEA and androstenedione-may play functional roles during juvenility as part of a life-stage specific system. We next review studies of adult male testosterone responses to competition, with these studies emphasizing men's involvement in individual and team sports. These studies show that men's testosterone responses differ with respect to variables such as playing home/away, winning/losing, and motivation. Field studies of human male hormones and sexual behavior also focus on testosterone, showing some evidence of patterned changes in men's testosterone to sexual activity. Moreover, life stage-specific changes in male androgens may structure age-related differences in sexual behavior, including decreases in sexual behavior with senescence. We overview the considerable body of research on male testosterone, partnerships and paternal care, noting the variation in social context and refinements in research design. A few field studies provide insight into relationships between partnering and paternal behavior and prolactin, oxytocin, and vasopressin. In the third section of the review, we discuss patterns, limitations and directions for future research. This includes discussion of conceptual and methodological issues future research might consider as well as opportunities for contributions in under-researched male life stages (juvenility, senescence) and hormones (e.g., vasopressin).

In March 2005, four students and three teachers from Boerne High School in Texas accompanied UTIG GK-12 Co-PIs Katherine Ellins and Ian Dalziel, and NSF GK-12 Fellow Ethan Perry to Tierra del Fuego to join an international team of scientists studying the climate-tectonic history recorded in Lago Fagnano, Tierra del Fuego, Argentina. For two weeks, students and teachers engaged in authentic scientific research that included geologic field mapping and reconnaissance, and student/teacher developed water and soils sampling routines. The Lago Fagnano experience enabled: (1) the Boerne High School group to be integrated into an active field research program and to bring tangible experiences, knowledge and high-quality data back to the classroom; (2) participating research scientists to convey the importance of their science to a wider audience; and (3) the NSF GK-12 Fellow to gain valuable experience in communicating the essential scientific knowledge and field skills to high school participants before field deployment. The GK-12 Fellow's bridging role through the course of the project enhanced his scientific understanding of the climate-tectonic setting of Tierra del Fuego, fostered the development of new professional contacts with research scientists and led to a fresh perspective on how research science can be integrated in high school science curriculum. The GK-12 Fellow served as the primary mentor to the K-12 participants and the liaison between UTIG research scientists and the Boerne High School group. The Fellow helped prepare the Boerne group for the field research experience and to design a research project using water and soil analyses to assess chemical and isotopic trends within the lake's watershed. Preparatory activities began three months prior to field deployment and included workshops, classroom visits and teleconferences aimed at teaching field skills (reading and creating geologic maps, compass measurements, GPS, field notebooks) and increasing participants' knowledge of geoscience concepts and regional tectonics. The Fellow blended inquiry- and discussion-based exercises to convey the relevance of the Lago Fagnano research. Interaction between the GK-12 Fellow and Boerne High School participants preceding, during and following the field experience was an important element in the success of this research experience for teachers and their students. This interaction benefited the high school students and teachers because they were able to grasp the fundamental goals of the research experience prior to arriving in the field, thereby ensuring that the time spent in the field was used efficiently to carry out the project. Long-term involvement in the planning, execution and synthesis of the experience provided the high school participants with a sense of ownership of the science conducted on Lago Fagnano. This field initiative represents the first time that both K-12 students and teachers were integrated into a field setting with UTIG research scientists. Such experiences are valuable because they demonstrate the true manner in which science is conducted and advance partnerships between university research institutions and K-12 schools. The level of mentoring that the GK-12 Fellow provided through all stages of the project maximized the potential benefits of such an experience.

Data Friction Meets Social Friction: Challenges for standardization in emerging fields of geoscience

NASA Astrophysics Data System (ADS)

Darch, P. T.

2017-12-01

Many interdisciplinary endeavors in the geosciences occur in emergent scientific fields. These fields are often characterized by heterogeneity of methods for production and collection of data, and by data scarcity. This paper presents findings about processes of methods standardization from a long-term case study of an emergent, data-scarce field, the deep subseafloor biosphere. Researchers come from many physical and life science backgrounds to study interactions between microbial life in the seafloor and the physical environment they inhabit. Standardization of methods for collecting data promises multiple benefits to this field, including: Addressing data scarcity through enabling greater data reuse and promoting better interoperability with large scale infrastructures; Fostering stronger collaborative links between researchers distributed across institutions and backgrounds. Ongoing standardization efforts in the field do not only involve scientific judgments about which among a range of methods is most efficient, least biased, or most reliable. Instead, these efforts also encounter multiple difficult social challenges, including: Lack of agreed upon criteria about how to judge competing methods: should efficiency, bias, or reliability take priority?; Lack of resources to carry out the work necessary to determine standards, particularly acute in emergent fields; Concerns that standardization is premature in such a new field, foreclosing the possibility of better methods being developed in the future; Concerns that standardization could prematurely shut down important scientific debates; Concerns among some researchers that their own work may become obsolete should the methods chosen as standard be different from their own. The success of these standardization efforts will depend on addressing both scientific and social dimensions, to ensure widespread acceptance among researchers in the field.

Understanding behavioral responses of fish to pheromones in natural freshwater environments

USGS Publications Warehouse

Johnson, Nicholas S.; Li, Weiming

2010-01-01

There is an abundance of experimental studies and reviews that describe odorant-mediated behaviors of fish in laboratory microcosms, but research in natural field conditions has received considerably less attention. Fish pheromone studies in laboratory settings can be highly productive and allow for controlled experimental designs; however, laboratory tanks and flumes often cannot replicate all the physical, physiological and social contexts associated with natural environments. Field experiments can be a critical step in affirming and enhancing understanding of laboratory discoveries and often implicate the ecological significance of pheromones employed by fishes. When findings from laboratory experiments have been further tested in field environments, often different and sometimes contradictory conclusions are found. Examples include studies of sea lamprey (Petromyzon marinus) mating pheromones and fish alarm substances. Here, we review field research conducted on fish pheromones and alarm substances, highlighting the following topics: (1) contradictory results obtained in laboratory and field experiments, (2) how environmental context and physiological status influences behavior, (3) challenges and constraints of aquatic field research and (4) innovative techniques and experimental designs that advance understanding of fish chemical ecology through field research.

SAGE (Summer of Applied Geophysical Experience) is a unique program of education and research in geophysical field methods for undergraduate and graduate students from any university and for professionals. The core program is held for 4 weeks each summer in New Mexico and for an additional week in the following academic year in San Diego for U.S. undergraduates supported by the NSF Research Experience for Undergraduates (REU) program. Since SAGE was initiated in 1983, 730 students have participated in the program. NSF REU funding for SAGE began in 1990 and 319 REU students have completed SAGE through 2011. The primary objectives of SAGE are to teach the major geophysical exploration methods (seismic, gravity, magnetics, electromagnetics); apply these methods to the solution of specific problems (environmental, archaeological, hydrologic, geologic structure and stratigraphy); gain experience in processing, modeling and interpretation of geophysical data; and integrate the geophysical models and interpretations with geology. Additional objectives of SAGE include conducting research on the Rio Grande rift of northern New Mexico, and providing information on geophysics careers and professional development experiences to SAGE participants. Successful education, field and research strategies that we have implemented over the years include: 1. learn by doing; 2. mix lecture/discussion, field work, data processing and analysis, modeling and interpretation, and presentation of results; 3. a two-tier team approach - method/technique oriented teams and interpretation/integration teams (where each team includes persons representing different methods), provides focus, in-depth study, opportunity for innovation, and promotes teamwork and a multi-disciplinary approach; 4. emphasis on presentations/reports - each team (and all team members) make presentation, each student completes a written report; 5. experiment design discussion - students help design field program and consider issues - safety, constraints, data quality/quantity, research objective, educational experience, survey parameters, why multidisciplinary?, etc.; 6. knowledge of multiple geophysical field methods (each student works with all methods); 7. information on geophysics careers and networking provided by industry visitors; 8. measures of success of the program include high rate of continuation to graduate school and careers in geophysics, support and feedback from industry participants and visitors, student evaluations at end of program, presentations at professional meetings, publications, and faculty evaluation of student work.

Exploring the use of Virtual Field Trips with elementary school teachers: A collaborative action research approach

NASA Astrophysics Data System (ADS)

Scott, Jeffrey Lance

This research examines how elementary school teachers, when supported, use Virtual Field Trips (VFTs) to address the curricula in meaningful ways. I conducted a qualitative study with six teachers, in a collaborative action research context over a six month period. The teachers, five males and one female, all taught either grade five or six and utilized Virtual Field Trips within a variety of curricula areas including science, social studies, music and language arts. In addition, the thesis examines resulting integration of technology into the regular classroom program as a product of the utilization of Virtual Field Trips. The process of collaborative action research was applied as a means of personal and professional growth both for the participants and the researcher/facilitator. By the end of the research study, all participants had learned to integrate Virtual Field Trips into their classroom program, albeit with different levels of success and in different curricula areas. The development of attitudes, skills and knowledge for students and teachers alike was fostered through the participation in Virtual Field Trips. A common concern regarding the utilization of Virtual Field Trips was the time spent locating an appropriate site that met curricula expectations. Participation in the collaborative action research process allowed each teacher to grow professionally, personally and socially. Each participant strongly encouraged the utilization of a long term project with a common area of exploration as a means for positive professional development. Implications and recommendations for future research on the utilization of Virtual Field Trips, as well as the viability of collaborative action research to facilitate teacher development are presented.

Three-dimensional printing, a technology used for decades in the industrial field, gains a lot of attention in the medical field for its potential benefits. With advancement of desktop printers, this technology is accessible and a lot of research is going on in the medical field. To evaluate its application in surgical field, which may include but not limited to surgical planning, surgical education, implants, and prosthesis, which are the focus of this review. Research was conducted by searching PubMed, Web of science, and other reliable sources. We included original articles and excluded articles based on animals, those more than 10 years old, and those not in English. These articles were evaluated, and relevant studies were included in this review. Three-dimensional printing shows a potential benefit in surgical application. Printed implants were used in patient in a few cases and show successful results; however, longer follow-up and more trials are needed. Surgical and medical education is believed to be more efficient with this technology than the current practice. Printed surgical instrument and surgical planning are also believed to improve with three-dimensional printing. Three-dimensional printing can be a very powerful tool in the near future, which can aid the medical field that is facing a lot of challenges and obstacles. However, despite the reported results, further research on larger samples and analytical measurements should be conducted to ensure this technology's impact on the practice.

Spirituality, religion, and health: over the last 15 years of field research (1999-2013).

Although several studies have examined the contribution of specific countries, journals, and authors in different scientific disciplines, little is known about the contribution of different world countries, journals, and authors to scientific research in the field of "Spirituality, religion, and health" (S/R). The present study aims to analyze the last 15 years of research in the field of spirituality and religiousness (S/R) through a bibliometric analysis. Using the Pubmed database, we retrieved all articles related to S/R field for the period 1999-2013. We then estimated the total number of publications, number of articles published per year, articles published per country, journals with most publications in S/R field, most productive authors, and most used keywords. We found a growth of publications in the last years, most from the United States and the United Kingdom and published in the English language. Noteworthy, some developing countries such as India, Brazil, Israel, and Iran are at higher positions in this list. The S/R articles were published in journals embracing all fields of research, including high impact journals. In the present study, we took a closer look at the field of "Spirituality, religion, and health," showing that this field of research has been constantly growing and consolidating in the scientific community.

Integrating Research and Education in a Study of Biocomplexity in Arctic Tundra Ecosystems: Costs, Results, and Benefits to the Research Agenda

NASA Astrophysics Data System (ADS)

Gould, W. A.; González, G.; Walker, D. A.

2006-12-01

The integration of research and education is one of the fundamental goals of our national science policy. There is strong interest to improve this integration at the graduate and undergraduate levels, with the general public, and with local and indigenous people. Efforts expended in integrating research and education can occur at the expense of research productivity and represent a cost. Results may include number of personnel involved, activities accomplished, research or other products produced. Benefits are difficult to quantify and may be short term and tangible, e.g. education-research projects enhancing research productivity with publications, or long-term and include intangibles such as personal interactions and experiences influencing career choices, the perception of research activities, enhanced communication, and direct or indirect influence on related research and educational projects. We have integrated the University field course Arctic Field Ecology with an interdisciplinary research project investigating the interactions of climate, vegetation, and permafrost in the study Biocomplexity of Arctic Tundra Ecosystems. The integration is designed to give students background in regional ecology; introduce students to the project objectives, methods, and personnel; provide for interaction with participating scientists; conduct research initiated by the class and instructors; and provide the opportunity to interact with indigenous people with interests in traditional ecological knowledge and land management. Our costs included increased logistical complexity and time-demands on the researchers and staff managing the integration. The educational component increased the size of the research group with the addition of 55 participants over the 4 field seasons of the study. Participants came from 7 countries and included 20 enrolled university students, 18 Inuit non student participants, 9 Inuit students, 3 visiting scientists, 3 staff, and 2 scientist-instructors. The educational component initiated 6 research studies at a series of eight sites along the complete climatic gradient of the North America Arctic. These include studies of variation in nonsorted circle morphology, climatic and cryoturbation effects on species diversity and community composition of plants and soil invertebrates, and an analysis of climatic and cryoturbation effects controls on litter decomposition and soil microbial biomass. A youth-elder-science camp was conducted which introduced Inuit students to permafrost and nonsorted circles. Four students have continued their involvement with the Biocomplexity study as graduate or post graduate students. Indirect benefits are difficult to assess but the integration has allowed a number of students to participate directly with the research team, drawn by the opportunity to gain education and experience over the course of a field season, and this participation has had synergistic benefits with the research agenda of the project.

Interdisciplinary research has consistently lower funding success.

PubMed

Bromham, Lindell; Dinnage, Russell; Hua, Xia

2016-06-30

Interdisciplinary research is widely considered a hothouse for innovation, and the only plausible approach to complex problems such as climate change. One barrier to interdisciplinary research is the widespread perception that interdisciplinary projects are less likely to be funded than those with a narrower focus. However, this commonly held belief has been difficult to evaluate objectively, partly because of lack of a comparable, quantitative measure of degree of interdisciplinarity that can be applied to funding application data. Here we compare the degree to which research proposals span disparate fields by using a biodiversity metric that captures the relative representation of different fields (balance) and their degree of difference (disparity). The Australian Research Council's Discovery Programme provides an ideal test case, because a single annual nationwide competitive grants scheme covers fundamental research in all disciplines, including arts, humanities and sciences. Using data on all 18,476 proposals submitted to the scheme over 5 consecutive years, including successful and unsuccessful applications, we show that the greater the degree of interdisciplinarity, the lower the probability of being funded. The negative impact of interdisciplinarity is significant even when number of collaborators, primary research field and type of institution are taken into account. This is the first broad-scale quantitative assessment of success rates of interdisciplinary research proposals. The interdisciplinary distance metric allows efficient evaluation of trends in research funding, and could be used to identify proposals that require assessment strategies appropriate to interdisciplinary research.

We summarize a portfolio of possible field experiments on solar radiation management (SRM) and related technologies. The portfolio is intended to support analysis of potential field research related to SRM including discussions about the overall merit and risk of such research as well as mechanisms for governing such research and assessments of observational needs. The proposals were generated with contributions from leading researchers at a workshop held in March 2014 at which the proposals were critically reviewed. The proposed research dealt with three major classes of SRM proposals: marine cloud brightening, stratospheric aerosols and cirrus cloud manipulation. The proposals are summarized here along with an analysis exploring variables such as space and time scale, risk and radiative forcing. Possible gaps, biases and cross-cutting considerations are discussed. Finally, suggestions for plausible next steps in the development of a systematic research programme are presented.

Saqr, Mohammed

2018-01-01

The number of publications in the field of medical education is still markedly low, despite recognition of the value of the discipline in the medical education literature, and exponential growth of publications in other fields. This necessitates raising awareness of the research methods and potential benefits of learning analytics (LA). The aim of this paper was to offer a methodological systemic review of empirical LA research in the field of medical education and a general overview of the common methods used in the field in general. Search was done in Medline database using the term “LA.” Inclusion criteria included empirical original research articles investigating LA using qualitative, quantitative, or mixed methodologies. Articles were also required to be written in English, published in a scholarly peer-reviewed journal and have a dedicated section for methods and results. A Medline search resulted in only six articles fulfilling the inclusion criteria for this review. Most of the studies collected data about learners from learning management systems or online learning resources. Analysis used mostly quantitative methods including descriptive statistics, correlation tests, and regression models in two studies. Patterns of online behavior and usage of the digital resources as well as predicting achievement was the outcome most studies investigated. Research about LA in the field of medical education is still in infancy, with more questions than answers. The early studies are encouraging and showed that patterns of online learning can be easily revealed as well as predicting students’ performance. PMID:29599699

Elementary school children's science learning from school field trips

NASA Astrophysics Data System (ADS)

Glick, Marilyn Petty

This research examines the impact of classroom anchoring activities on elementary school students' science learning from a school field trip. Although there is prior research demonstrating that students can learn science from school field trips, most of this research is descriptive in nature and does not examine the conditions that enhance or facilitate such learning. The current study draws upon research in psychology and education to create an intervention that is designed to enhance what students learn from school science field trips. The intervention comprises of a set of "anchoring" activities that include: (1) Orientation to context, (2) Discussion to activate prior knowledge and generate questions, (3) Use of field notebooks during the field trip to record observations and answer questions generated prior to field trip, (4) Post-visit discussion of what was learned. The effects of the intervention are examined by comparing two groups of students: an intervention group which receives anchoring classroom activities related to their field trip and an equivalent control group which visits the same field trip site for the same duration but does not receive any anchoring classroom activities. Learning of target concepts in both groups was compared using objective pre and posttests. Additionally, a subset of students in each group were interviewed to obtain more detailed descriptive data on what children learned through their field trip.

Since most experiments regarding the symbiosis between arbuscular mycorrhizal (AM) fungi and their host plants under salinity stress have been performed only under greenhouse conditions, this research work was also conducted under field conditions. The effects of three AM species including Glomus mosseae, G. etunicatum and G. intraradices on the nutrient uptake of different wheat cultivars (including Roshan, Kavir and Tabasi) under field and greenhouse (including Chamran and Line 9) conditions were determined. At field harvest, the concentrations of N, Ca, Mg, Fe, Cu, and Mn, and at greenhouse harvest, plant growth, root colonization and concentrations of different nutrients including N, K, P, Ca, Mg, Mn, Cu, Fe, Zn, Na and Cl were determined. The effects of wheat cultivars on the concentrations of N, Ca, and Mn, and of all nutrients were significant at field and greenhouse conditions, respectively. In both experiments, AM fungi significantly enhanced the concentrations of all nutrients including N, K, P, Ca, Mg, Mn, Cu, Fe, Zn, Na and Cl. The synergistic and enhancing effects of co-inoculation of AM species on plant growth and the inhibiting effect of AM species on Na(+) rather than on Cl(-) uptake under salinity are also among the important findings of this research work.

Scientifically defensible predictions of field scale U(VI) transport in groundwater requires an understanding of key processes at multiple scales. These scales range from smaller than the sediment grain scale (less than 10 μm) to as large as the field scale which can extend over several kilometers. The key processes that need to be considered include both geochemical reactions in solution and at sediment surfaces as well as physical transport processes including advection, dispersion, and pore-scale diffusion. The research summarized in this report includes both experimental and modeling results in batch, column and tracer tests. The objectives of this research were to: (1) quantify the rates of U(VI) desorption from sediments acquired from a uranium contaminated aquifer in batch experiments;(2) quantify rates of U(VI) desorption in column experiments with variable chemical conditions, and(3) quantify nonreactive tracer and U(VI) transport in field tests.

Audio is an information-rich component of multimedia. Information can be extracted from audio in a number of different ways, and thus there are several established audio signal analysis research fields. These fields include speech recognition, speaker recognition, audio segmentation and classification, and audio finger-printing. The information that can be extracted from tools and methods developed in these fields can greatly enhance multimedia systems. In this paper, we present the current state of research in each of the major audio analysis fields. The goal is to introduce enough back-ground for someone new in the field to quickly gain high-level understanding andmore » to provide direction for further study.« less

Social neuroscience and its potential contribution to psychiatry

PubMed Central

Cacioppo, John T; Cacioppo, Stephanie; Dulawa, Stephanie; Palmer, Abraham A

2014-01-01

Most mental disorders involve disruptions of normal social behavior. Social neuroscience is an interdisciplinary field devoted to understanding the biological systems underlying social processes and behavior, and the influence of the social environment on biological processes, health and well-being. Research in this field has grown dramatically in recent years. Active areas of research include brain imaging studies in normal children and adults, animal models of social behavior, studies of stroke patients, imaging studies of psychiatric patients, and research on social determinants of peripheral neural, neuroendocrine and immunological processes. Although research in these areas is proceeding along largely independent trajectories, there is increasing evidence for connections across these trajectories. We focus here on the progress and potential of social neuroscience in psychiatry, including illustrative evidence for a rapid growth of neuroimaging and genetic studies of mental disorders. We also argue that neuroimaging and genetic research focused on specific component processes underlying social living is needed. PMID:24890058

The increasing rate of outbreaks in humans of zoonotic diseases requires detailed examination of the education, research, and practice of animal health and its connection to human health. This study investigated the collaboration network of different fields engaged in conducting zoonotic research from a transdisciplinary perspective. Examination of the dynamics of this network for a 33-year period from 1980 to 2012 is presented through the development of a large scientometric database from Scopus. In our analyses we compared several properties of these networks, including density, clustering coefficient, giant component, and centrality measures over time. We also elicited patterns in different fields of study collaborating with various other fields for zoonotic research. We discovered that the strongest collaborations across disciplines are formed among the fields of medicine; biochemistry, genetics, and molecular biology; immunology and microbiology; veterinary; agricultural and biological sciences; and social sciences. Furthermore, the affiliation network is growing overall in terms of collaborative research among different fields of study such that more than two-thirds of all possible collaboration links among disciplines have already been formed. Our findings indicate that zoonotic research scientists in different fields (human or animal health, social science, earth and environmental sciences, engineering) have been actively collaborating with each other over the past 11 years.

The initial goal of occupational reproductive health research is to effectively study the many toxicants, physical agents, and biomechanical and psychosocial stressors that may constitute reproductive hazards in the workplace. Although the main objective of occupational reproductive researchers and clinicians is to prevent recognized adverse reproductive outcomes, research has expanded to include a broader spectrum of chronic health outcomes potentially affected by reproductive toxicants. To aid in achieving these goals, the National Institute for Occupational Safety and Health, along with its university, federal, industry, and labor colleagues, formed the National Occupational Research Agenda (NORA) in 1996. NORA resulted in 21 research teams, including the Reproductive Health Research Team (RHRT). In this report, we describe progress made in the last decade by the RHRT and by others in this field, including prioritizing reproductive toxicants for further study; facilitating collaboration among epidemiologists, biologists, and toxicologists; promoting quality exposure assessment in field studies and surveillance; and encouraging the design and conduct of priority occupational reproductive studies. We also describe new tools for screening reproductive toxicants and for analyzing mode of action. We recommend considering outcomes such as menopause and latent adverse effects for further study, as well as including exposures such as shift work and nanomaterials. We describe a broad domain of scholarship activities where a cohesive system of organized and aligned work activities integrates 10 years of team efforts and provides guidance for future research.

Persistent Identifiers for Field Deployments: A Missing Link in the Provenance Chain

NASA Astrophysics Data System (ADS)

Arko, R. A.; Ji, P.; Fils, D.; Shepherd, A.; Chandler, C. L.; Lehnert, K.

2016-12-01

Research in the geosciences is characterized by a wide range of complex and costly field deployments including oceanographic cruises, submersible dives, drilling expeditions, seismic networks, geodetic campaigns, moored arrays, aircraft flights, and satellite missions. Each deployment typically produces a mix of sensor and sample data, spanning a period from hours to decades, that ultimately yields a long tail of post-field products and publications. Publishing persistent, citable identifiers for field deployments will facilitate 1) preservation and reuse of the original field data, 2) reproducibility of the resulting publications, and 3) recognition for both the facilities that operate the platforms and the investigators who secure funding for the experiments. In the ocean domain, sharing unique identifiers for field deployments is a familiar practice. For example, the Biological and Chemical Oceanography Data Management Office (BCO-DMO) routinely links datasets to cruise identifiers published by the Rolling Deck to Repository (R2R) program. In recent years, facilities have started to publish formal/persistent identifiers, typically Digital Object Identifiers (DOIs), for field deployments including seismic networks, oceanographic cruises, and moored arrays. For example, the EarthChem Library (ECL) publishes a DOI for each dataset which, if it derived from an oceanographic research cruise on a US vessel, is linked to a DOI for the cruise published by R2R. Work is underway to create similar links for the IODP JOIDES Resolution Science Operator (JRSO) and the Continental Scientific Drilling Coordination Office (CSDCO). We present results and lessons learned including a draft schema for publishing field deployments as DataCite DOI records; current practice for linking these DOIs with related identifiers such as Open Researcher and Contributor IDs (ORCIDs), Open Funder Registry (OFR) codes, and International Geo Sample Numbers (IGSNs); and consideration of other identifier types for field deployments such as UUIDs and Handles.

To summarize the scientific priorities and potential future research directions for pediatric critical care research discussed by a panel of experts at the inaugural Strategic Planning Conference of the Pediatric Trauma and Critical Illness Branch of the Eunice Kennedy Shriver National Institute of Child Health and Human Development. Expert opinion expressed during the Strategic Planning Conference. Not applicable. Chaired by an experienced expert from the field, issues relevant to the conduct of pediatric critical care research were discussed and debated by the invited participants. Common themes and suggested priorities were identified and coalesced. Of the many pathophysiologic conditions discussed, the multiple organ dysfunction syndrome emerged as a topic in need of more study that is most relevant to the field. Additionally, the experts offered that the interrelationship and impact of critical illness on child development and family functioning are important research priorities. Consequently, long-term outcomes research was encouraged. The expert group also suggested that multidisciplinary conferences are needed to help identify key knowledge gaps to advance and direct research in the field. The Pediatric Critical Care and Trauma Scientist Development National K12 Program and the Collaborative Pediatric Critical Care Research Network were recognized as successful and important programs supported by the branch. The development of core data resources including biorepositories with robust phenotypic data using common data elements was also suggested to foster data sharing among investigators and to enhance disease diagnosis and discovery. Multicenter clinical trials and innovative study designs to address understudied and poorly understood conditions were considered important for field advancement. Finally, the growth of the pediatric critical care research workforce was offered as a priority that could be spawned in many ways including by expanded transdisciplinary and multiprofessional collaboration and diversity representation.

Introduction: Three-dimensional printing, a technology used for decades in the industrial field, gains a lot of attention in the medical field for its potential benefits. With advancement of desktop printers, this technology is accessible and a lot of research is going on in the medical field. Objective: To evaluate its application in surgical field, which may include but not limited to surgical planning, surgical education, implants, and prosthesis, which are the focus of this review. Methods: Research was conducted by searching PubMed, Web of science, and other reliable sources. We included original articles and excluded articles based on animals, those more than 10 years old, and those not in English. These articles were evaluated, and relevant studies were included in this review. Discussion: Three-dimensional printing shows a potential benefit in surgical application. Printed implants were used in patient in a few cases and show successful results; however, longer follow-up and more trials are needed. Surgical and medical education is believed to be more efficient with this technology than the current practice. Printed surgical instrument and surgical planning are also believed to improve with three-dimensional printing. Conclusion: Three-dimensional printing can be a very powerful tool in the near future, which can aid the medical field that is facing a lot of challenges and obstacles. However, despite the reported results, further research on larger samples and analytical measurements should be conducted to ensure this technology's impact on the practice. PMID:26301002

Dickow, Benjamin

2012-01-01

Informal science education (ISE) is playing an increasingly important role in how and where the public engages with science. A growing body of research is showing that people learn the majority of their science knowledge outside of school (Falk & Dierking, 2010). The ISE field includes a wide variety of sources, including the internet, TV programs, magazines, hobby clubs and museums. These experiences touch large numbers of people throughout their lifetimes. If you would like to share your research with the public, ISE can be an effective conduit for meaningful science communication. However, because the ISE field is so diverse, it can be overwhelming with its multiple entry points. If you already are part of an ISE initiative, knowing how to access the most useful resources easily can also be daunting. CAISE, the Center for Advancement of Informal Science Education, is a resource center for the ISE field funded by the National Science Foundation (NSF). CAISE can help connect you to the knowledge and people of ISE, through its website, products and in-person convenings. The proposed CAISE presentation will outline the diversity of the field and concisely present data that will make the case for the impact of ISE. We will focus on examples of successful programs that connect science with the public and that bring together AAS's science research community with practitioners and researchers within ISE. Pathways to various ISE resources in the form of current CAISE initiatives will be described as well. The presentation will include an interview section in which a CAISE staff member will ask questions of a scientist involved in an ISE initiative in order to detail one example of how ISE can be a valuable tool for engaging the public in science. Time for audience Q&A also will be included in the session.

Effects of noise and electromagnetic fields on reproductive outcomes.

PubMed Central

Meyer, R E; Aldrich, T E; Easterly, C E

1989-01-01

Much public health research has been directed to studies of cancer risks due to chemical agents. Recently, increasing attention has been given to adverse reproductive outcomes as another, shorter-term biologic indicator of public health impact. Further, several low-level ubiquitous physical agents have been implicated recently as possibly affecting human health. These physical factors (noise and electromagnetic fields) represent difficult topics for research with epidemiologic study methods. This paper provides a brief review of the published data related to the risk of adverse reproductive outcomes and exposure to noise or electromagnetic fields. The discussion includes ideas for possible biologic mechanisms, considerations for exposure assessment, and suggestions for epidemiologic research. PMID:2667980

2017-02-15

Collaborative research is common in many medical disciplines; however, the field of orthopaedics has been relatively slow to adopt this type of research approach. Collaborative research efforts can occur between multiple institutions and, in some instances, may benefit from subspecialty society sponsorship. Collaborative research efforts between several research spheres within a single institution also can be advantageous. Collaborative research has many benefits, including a larger number of patients in studies, more power in the research, and better generalizability. In addition, collaborative research efforts allow resources to be pooled within and between institutions. The challenges of collaborative research include data management, funding, and the publication of manuscripts that have many authors.

Field endocrinology of nonhuman primates: past, present, and future.

PubMed

Higham, James P

2016-08-01

In the past few decades, research on nonhuman primate endocrinology has moved from the lab to the field, leading to a huge increase in both the breadth and depth of primate field studies. Here, I discuss the past, present, and future of primate field endocrinology. I review the history of the field, and go on to discuss methodological developments and the issues that they sometimes entail. Next, I consider ways in which we might conceptualize the role of hormones, and focus on the need to distinguish proximate from ultimate levels of explanation. Current potentially problematic issues in the field include: 1) an inability to obtain noninvasive measurements of Central Nervous System (CNS) rather than peripheral hormone concentrations; 2) research questions that become stuck (e.g., questions regarding sexual swelling expression mechanisms); 3) data dredging and post-hoc linking of hormones to any plausible variable, leading to a lack of clarity on their role in animal ecology and behavior. I finish by discussing several unanswered questions that might benefit from further research. These are how we might: 1) best obtain measurements for CNS hormone concentrations non-invasively; 2) measure hormone receptor expression alongside hormone concentrations; 3) consider the human endocrinology literature more thoroughly and perhaps take more multimarker approaches; 4) better consider the social environment, including audience and dyadic familiarity effects; and 5) apply our findings to conservation issues.

2014-12-01

This fall marks the 10th year in which we have run a research-project-based educational program for high school students and science teachers at the Lamont-Doherty Earth Observatory. This summer's cohort included 31 teenagers, 7 science teachers, and 16 college students, most of whom are returning to the program to help run the research projects. Nearly all of our students attend non-competitive-entry public schools in NYC or the neighborhoods around the Observatory. Over 80% are from under-served minority populations. Most receive Title I/III assistance. About 60% are young women. During the past 10 years, nearly all of our participants have gone on to 4-year colleges. About half are declaring science and engineering majors. Our students receive scholarship support at rates several times higher than their graduating peers, including 5 Gates Millennium scholars over the past 5 years. Our science is centered on studies of a nearby tidal wetland, where we have expanded from fish collections in year one to include everything from sediment core analysis to soil chemistry to nutrient cycles to the local food web. In this presentation we will look back over 10 years of experience and focus on what lessons can be learned about (1) how to engage teams of young investigators in authentic scientific research; (2) what cultural/organizational structures encourage them to make use of place- and project-based learning and (3) what the participants themselves report as the most useful aspects of our programming. The presentation will include video clips from the students' field experiences and from reflective interviews with "graduates".

Substance use disorders in Arab countries: research activity and bibliometric analysis

PubMed Central

2014-01-01

Background Substance use disorders, which include substance abuse and substance dependence, are present in all regions of the world including Middle Eastern Arab countries. Bibliometric analysis is an increasingly used tool for research assessment. The main objective of this study was to assess research productivity in the field of substance use disorders in Arab countries using bibliometric indicators. Methodology Original or review research articles authored or co-authored by investigators from Arab countries about substance use disorders during the period 1900 – 2013 were retrieved using the ISI Web of Science database. Research activity was assessed by analyzing the annual research productivity, contribution of each Arab country, names of journals, citations, and types of abused substances. Results Four hundred and thirteen documents in substance use disorders were retrieved. Annual research productivity was low but showed a significant increase in the last few years. In terms of quantity, Kingdom of Saudi Arabia (83 documents) ranked first in research about substance use disorders while Lebanon (17.4 documents per million) ranked first in terms of number of documents published per million inhabitants. Retrieved documents were found in different journal titles and categories, mostly in Drug and Alcohol Dependence Journal. Authors from USA appeared in 117 documents published by investigators from Arab countries. Citation analysis of retrieved documents showed that the average citation per document was 10.76 and the h - index was 35. The majority of retrieved documents were about tobacco and smoking (175 documents) field while alcohol consumption and abuse research was the least with 69 documents. Conclusion The results obtained suggest that research in this field was largely neglected in the past. However, recent research interest was observed. Research output on tobacco and smoking was relatively high compared to other substances of abuse like illicit drugs and medicinal agents. Governmental funding for academics and mental health graduate programs to do research in the field of substance use disorders is highly recommended. PMID:25148888

Scalar fields in black hole spacetimes

Thuestad, Izak; Khanna, Gaurav; Price, Richard H.

2017-07-01

The time evolution of matter fields in black hole exterior spacetimes is a well-studied subject, spanning several decades of research. However, the behavior of fields in the black hole interior spacetime has only relatively recently begun receiving some attention from the research community. In this paper, we numerically study the late-time evolution of scalar fields in both Schwarzschild and Kerr spacetimes, including the black hole interior. We recover the expected late-time power-law "tails" on the exterior (null infinity, timelike infinity, and the horizon). In the interior region, we find an interesting oscillatory behavior that is characterized by the multipole index ℓ of the scalar field. In addition, we also study the extremal Kerr case and find strong indications of an instability developing at the horizon.

Technology-Enhanced Science: Using an Online Blog to Share a Collaborative Field Study for Research and Education

NASA Astrophysics Data System (ADS)

Mccann, A. R.; Cardace, D.; Carnevale, D.

2011-12-01

The role of technology is an increasingly important resource in preparing students for the future. The Internet is a widely accessible tool. Technology has also made us more connected, allowing constant communication and instantaneous data sharing. Public utilities such as those found on the web, including blogs, are a means to convey scientific research in rapid, useful ways. This tool is ideal for newly emerging fields, allowing up-to-date collaboration and referencing of ongoing studies, as well as bringing students virtually into the field or laboratory through videos, pictures, and records of project work. Astrobiology is a high interest topic, integrating geology, chemistry, biology, and physics. Terrestrial Mars analog environments are compelling in that they shed light on unusual opportunities for diverse life in settings beyond Earth. For this study, the analog site locality is at the University of California-Davis McLaughlin Natural Reserve in the Coast Range Ophiolite, a portion of actively serpentinizing, uplifted oceanic material in northern California (see companion poster, McCann et al., Mineralogy of Surface Serpentinite Outcrops in the Coast Range Ophiolite: Implications for the Deep Biosphere and Astrobiology). Our research objective is to monitor the activity taking place within the subsurface biosphere through an interdisciplinary approach involving biogeochemists, microbiologists, organic geochemists, and geologists. The study of serpentinization with astrobiological ground-truthing is a relatively new and promising field. Scientific field procedures are constantly being modified as they are applied. In order to better collaborate study efforts, a daily field journal is being written, recording ideas, discussions, procedures, problems, solutions, and results. It serves as an informal report, including pictures and video clips of the field activity. The journal is maintained as an online blog for ease of use and accessibility, as well as public comment. Its secondary purpose is to serve as a resource oriented toward high school science classrooms interested in cutting edge scientific endeavors. Included are video interviews of each participating scientist, covering topics such as professional background, past studies, their parts in the ongoing project and what they hope to gain through this research. By piecing together the various scientific approaches with the procedural field work, I am simplifying the massive amount of details involved between proposing a project and having a presentable result. As a high school student, the enormity of research possibilities can be in awe-inspiring contrast with the precision of the end result. This blog is interlocking the important components of our field campaign so that the audience will understand better the tasks involved in the field of scientific research. It not only will bring clarity and realism to the scientific process, but will serve to convey the passion and life involved in the research by the people that love what they do.

In addition to the above four research areas, work was continued on plasma diagnostic development, and the development of new state-of-the-art data analysis and reduction methods, including software development for online reduction of Langmuir probe, capacitive probe, and other diagnostic information. Also being developed is the capability to analyze electrostatic potential fluctuations by the methods of nonlinear dynamics. An important part of the research program was the training of graduate and undergraduate research assistants in state-of-the-art methods in the fields of high temperature plasma physics, plasma diagnostics, communications, and related areas.

How to locate and appraise qualitative research in complementary and alternative medicine

PubMed Central

2013-01-01

Background The aim of this publication is to present a case study of how to locate and appraise qualitative studies for the conduct of a meta-ethnography in the field of complementary and alternative medicine (CAM). CAM is commonly associated with individualized medicine. However, one established scientific approach to the individual, qualitative research, thus far has been explicitly used very rarely. This article demonstrates a case example of how qualitative research in the field of CAM studies was identified and critically appraised. Methods Several search terms and techniques were tested for the identification and appraisal of qualitative CAM research in the conduct of a meta-ethnography. Sixty-seven electronic databases were searched for the identification of qualitative CAM trials, including CAM databases, nursing, nutrition, psychological, social, medical databases, the Cochrane Library and DIMDI. Results 9578 citations were screened, 223 articles met the pre-specified inclusion criteria, 63 full text publications were reviewed, 38 articles were appraised qualitatively and 30 articles were included. The search began with PubMed, yielding 87% of the included publications of all databases with few additional relevant findings in the specific databases. CINHAL and DIMDI also revealed a high number of precise hits. Although CAMbase and CAM-QUEST® focus on CAM research only, almost no hits of qualitative trials were found there. Searching with broad text terms was the most effective search strategy in all databases. Conclusions This publication presents a case study on how to locate and appraise qualitative studies in the field of CAM. The example shows that the literature search for qualitative studies in the field of CAM is most effective when the search is begun in PubMed followed by CINHAL or DIMDI using broad text terms. Exclusive CAM databases delivered no additional findings to locate qualitative CAM studies. PMID:23731997

However, attempts to systematically map the entirety of the research field are lacking. This gap can be filled with a bibliometric study, where publication-specific data such as citations, journals, authors, and keywords are used to provide a systematic overview of a specific field. Such analyses will help researchers better position their work. The objective of this review was to use bibliometric data to provide an overview of the eHealth and mHealth research field related to physical activity, sedentary behavior, and diet. The Web of Science (WoS) Core Collection was searched to retrieve all existing and highly cited (as defined by WoS) physical activity, sedentary behavior, and diet related eHealth and mHealth research papers published in English between January 1, 2000 and December 31, 2016. Retrieved titles were screened for eligibility, using the abstract and full-text where needed. We described publication trends over time, which included journals, authors, and countries of eligible papers, as well as their keywords and subject categories. Citations of eligible papers were compared with those expected based on published data. Additionally, we described highly-cited papers of the field (ie, top ranked 1%). The search identified 4805 hits, of which 1712 (including 42 highly-cited papers) were included in the analyses. Publication output increased on an average of 26% per year since 2000, with 49.00% (839/1712) of papers being published between 2014 and 2016. Overall and throughout the years, eHealth and mHealth papers related to physical activity, sedentary behavior, and diet received more citations than expected compared with papers in the same WoS subject categories. The Journal of Medical Internet Research published most papers in the field (9.58%, 164/1712). Most papers originated from high-income countries (96.90%, 1659/1717), in particular the United States (48.83%, 836/1712). Most papers were trials and studied physical activity. Beginning in 2013, research on Generation 2 technologies (eg, smartphones, wearables) sharply increased, while research on Generation 1 (eg, text messages) technologies increased at a reduced pace. Reviews accounted for 20 of the 42 highly-cited papers (n=19 systematic reviews). Social media, smartphone apps, and wearable activity trackers used to encourage physical activity, less sedentary behavior, and/or healthy eating were the focus of 14 highly-cited papers. This study highlighted the rapid growth of the eHealth and mHealth physical activity, sedentary behavior, and diet research field, emphasized the sizeable contribution of research from high-income countries, and pointed to the increased research interest in Generation 2 technologies. It is expected that the field will grow and diversify further and that reviews and research on most recent technologies will continue to strongly impact the field. ©Andre Matthias Müller, Carol A Maher, Corneel Vandelanotte, Melanie Hingle, Anouk Middelweerd, Michael L Lopez, Ann DeSmet, Camille E Short, Nicole Nathan, Melinda J Hutchesson, Louise Poppe, Catherine B Woods, Susan L Williams, Petra A Wark.

Whither field hydrology? The need for discovery science and outrageous hydrological hypotheses

NASA Astrophysics Data System (ADS)

Burt, T. P.; McDonnell, J. J.

2015-08-01

Field hydrology is on the decline. Meanwhile, the need for new field-derived insight into the age, origin and pathway of water in the headwaters, where most runoff is generated, is more needed than ever. Water Resources Research (WRR) has included some of the most influential papers in field-based runoff process understanding, particularly in the formative years when the knowledge base was developing rapidly. Here we take advantage of this 50th anniversary of the journal to highlight a few of these important field-based papers and show how field scientists have posed strong and sometimes outrageous hypotheses—approaches so needed in an era of largely model-only research. We chronicle the decline in field work and note that it is not only the quantity of field work that is diminishing but its character is changing too: from discovery science to data collection for model parameterization. While the latter is a necessary activity, the loss of the former is a major concern if we are to advance the science of watershed hydrology. We outline a vision for field research to seek new fundamental understanding, new mechanistic explanations of how watershed systems work, particularly outside the regions of traditional focus.

In recent years, bibliometric science has been frequently applied in the development and evaluation of scientific research. This work presents a bibliometric analysis for the research work performed in the field of geodesy "science of the measurement and mapping of the earth surface including its external gravity field". The objective of this work is to present a complete overview of the generated research on this field to assemble and study the most important publications occurred during the past seven years. The analysis was performed including the SCOPUS and WEB OF SCIENCE databases for all the geodetic scientific articles published between 2000 and 2006. The search profile was designed considering a strategy to seek for titles and article descriptors using the terms geodesy and geodetic and some other terms associated with the topics: geodetic surfaces, vertical measurements, reference systems and frames, modern space-geodetic techniques and satellite missions. Some preliminary results had been achieved specifically Bradford law of distribution for journals and education institutes, and Lotka's law for authors that also includes the cooperation between countries in terms of writing together scientific articles. In the particular case of distributions, the model suggested by Egghe (2002) was adopted for determining the cores.

Mixed methods studies are been increasingly applied to a diversity of fields. In this paper, we discuss the growing use-and enormous potential-of mixed methods research in the field of sport and physical activity. A second aim is to contribute to strengthening the characteristics of mixed methods research by showing how systematic observation offers rigor within a flexible framework that can be applied to a wide range of situations. Observational methodology is characterized by high scientific rigor and flexibility throughout its different stages and allows the objective study of spontaneous behavior in natural settings, with no external influence. Mixed methods researchers need to take bold yet thoughtful decisions regarding both substantive and procedural issues. We present three fundamental and complementary ideas to guide researchers in this respect: we show why studies of sport and physical activity that use a mixed methods research approach should be included in the field of mixed methods research, we highlight the numerous possibilities offered by observational methodology in this field through the transformation of descriptive data into quantifiable code matrices, and we discuss possible solutions for achieving true integration of qualitative and quantitative findings.

Work motivation is a topic of crucial importance to the success of organizations and societies and the well-being of individuals. We organize the work motivation literature over the last century using a meta-framework that clusters theories, findings, and advances in the field according to their primary focus on (a) motives, traits, and motivation orientations (content); (b) features of the job, work role, and broader environment (context); or (c) the mechanisms and processes involved in choice and striving (process). Our integrative review reveals major achievements in the field, including more precise mapping of the psychological inputs and operations involved in motivation and broadened conceptions of the work environment. Cross-cutting trends over the last century include the primacy of goals, the importance of goal striving processes, and a more nuanced conceptualization of work motivation as a dynamic, goal-directed, resource allocation process that unfolds over the related variables of time, experience, and place. Across the field, advances in methodology and measurement have improved the match between theory and research. Ten promising directions for future research are described and field experiments are suggested as a useful means of bridging the research-practice gap.

NASA Astrophysics Data System (ADS)

Kim, D. Y.; Marinelli, R. L.; Heidelberg, K., IV

2014-12-01

Studies have shown that undergraduate participation in research opportunities strengthens the retention of students in STEM fields. Increasing students' confidence levels in their scientific abilities, aiding in the development of their scientific identity, and strengthening their sense of belonging to a scientific community have been cited as important contributing factors. Research field stations offer unique advantages that amplify these benefits by challenging students to plan and work in the field, enhancing networking opportunities with multi-disciplinary professionals from numerous institutions and hierarchical levels, and creating a stronger sense of belonging and comradery within a science community. The USC Wrigley Institute for Environmental Studies' (WIES) Research Experiences for Undergraduates (REU) program is an 8-week program that begins on the main USC campus in Los Angeles and moves to a marine field station on Catalina Island during weeks 2-7, before returning to the mainland to complete the last week of the program. This unique model provides REU students with an opportunity to become integrated into faculty mentors' labs on the main campus, while exposing them to life as a researcher at a field station, both of which contribute significantly to the students' development as a scientist. Here, we present the WIES REU model and include a discussion of benefits and challenges to this unique infrastructure.

Semantic Data And Visualization Techniques Applied To Geologic Field Mapping

Geologic field mapping involves the use of technology before, during, and after visiting a site. Geologists utilize hardware such as Global Positioning Systems (GPS) connected to mobile computing platforms such as tablets that include software such as ESRI's ArcPad and other software to produce maps and figures for a final analysis and report. Hand written field notes contain important information and drawings or sketches of specific areas within the field study. Our goal is to collect and geo-tag final and raw field data into a cyber-infrastructure environment with an ontology that allows for large data processing, visualization, sharing, and searching, aiding in connecting field research with prior research in the same area and/or aid with experiment replication. Online searches of a specific field area return results such as weather data from NOAA and QuakeML seismic data from USGS. These results that can then be saved to a field mobile device and searched while in the field where there is no Internet connection. To accomplish this we created the GeoField ontology service using the Web Ontology Language (OWL) and Protégé software. Advanced queries on the dataset can be made using reasoning capabilities can be supported that go beyond a standard database service. These improvements include the automated discovery of data relevant to a specific field site and visualization techniques aimed at enhancing analysis and collaboration while in the field by draping data over mobile views of the site using augmented reality. A case study is being performed at University of Texas at El Paso's Indio Mountains Research Station located near Van Horn, Texas, an active multi-disciplinary field study site. The user can interactively move the camera around the study site and view their data digitally. Geologist's can check their data against the site in real-time and improve collaboration with another person as both parties have the same interactive view of the data.

The Best and the Brightest in Geosciences: Broadening Representation in the Field

NASA Astrophysics Data System (ADS)

Geoscience research in government agencies and universities across the US is anchored by data collection from field and lab experiments. In these settings, the composition and the culture of the environment can be less welcoming for individuals from groups that are traditionally underrepresented in the geosciences. Ongoing efforts to address diversity and inclusion in the field and lab include top-down approaches that provide support and training for established geoscience leaders and bottom-up approaches that offer research internships and fellowships for students. To achieve success, effective strategies for broadening representation in the field must be developed and shared across the geosciences community to advance scientific innovation and create opportunities for success.

Scientifically defensible predictions of field scale U(VI) transport in groundwater requires an understanding of key processes at multiple scales. These scales range from smaller than the sediment grain scale (less than 10 μm) to as large as the field scale which can extend over several kilometers. The key processes that need to be considered include both geochemical reactions in solution and at sediment surfaces as well as physical transport processes including advection, dispersion, and pore-scale diffusion. The research summarized in this report includes both experimental and modeling results in batch, column and tracer tests. The objectives of this research weremore » to: (1) quantify the rates of U(VI) desorption from sediments acquired from a uranium contaminated aquifer in batch experiments;(2) quantify rates of U(VI) desorption in column experiments with variable chemical conditions, and(3) quantify nonreactive tracer and U(VI) transport in field tests.« less

Family psychology: Past and future reflections on the field.

Parke, Ross D

2017-04-01

Prominent issues in the field of family psychology during my term as editor (1998-2003) of this journal were briefly noted, including a focus on marital issues, divorce, remarriage and family conflict. Parenting, attachment and parent-child relationships were also significant topics in this period. Special sections of the journal focused on cultural variations, families and the law, families and religion, and family routines and rituals. Several neglected issues that need more attention in the future were noted. These include the need to recognize the embeddedness of families in socioecological contexts, the importance of monitoring the impact of secular changes on families, and the value and limitations of viewing family psychology as a separate field. Other topics for a future agenda include the challenge of defining "family" in the midst of changing family forms, the effects of technological change on families, and the challenges of integrating biological research into the family psychology agenda. A multilevel bio-social approach to family research was recommended. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

The Yosemite Research Training in Environmental Science offers undergraduate students a unique opportunity to actively experience field research in Environmental Science in a premier National Park, over a nine-week period in the summer. The Yosemite REU is a collaboration between three institutions: the University of California at Merced, Yosemite National Park, and the USGS Western Ecological Research Center. Student activities mainly consist of individual research projects, spanning a broad range of disciplines such as Ecology, Geosciences, Biodiversity, Conservation, Restoration, and Hydrology. All projects include a strong field component. Students are exposed to the benefits of multi-disciplinary research in weekly meetings in which all students talk about their most recent work. Students present their research in Yosemite Valley at the end of the program before a public audience (including visitors). Research training is provided by mentors from UC Merced (Schools of Natural Sciences, Engineering, and Social Sciences) and the USGS Western Ecological Research Center. In addition to their interactions with their mentors and other faculty, students have opportunities to meet with NPS professionals engaged in park-related activities, to learn more about the integration of science with resources management and about potential careers in research and science outside academia. Students also participate in field trips led by UCM, USGS, and NPS scientists, focusing on Yosemite and the Sierra Nevada. Students attend a weekly seminar in Environmental Science with a broad diversity of speakers, including researchers as well as other science-related professionals, such as freelance science writers and illustrators, as well as NPS scientists and staff. Finally, student participants engage in several other activities, including outreach (e.g., a day-long meeting with high-school Central Valley students from underrepresented minorities). The Yosemite REU has already run for 2 years (with funds still available for another summer in 2010). Each year, eight students have been selected from a large pool of at least 150 complete applications, nationwide (with about 20 to 25% being students from under-represented minorities). Each year, five students out of eight have been from under-represented minorities.

Pulse laser propulsion (PLP) is an advanced propulsion concept can be used across a variety of fields with a wide range of applications. PLP reflects superior payload as well as decreased launch costs in comparison with other conventional methods of producing thrust, such as chemical propulsion or electric propulsion. Numerous researchers have attempted to exploit the potential applications of PLP. This paper first reviews concepts relevant to PLP, including the propulsion modes, breakdown regimes, and propulsion efficiency; the propulsion targets for different materials with the pulse laser are then discussed in detail, including the propulsion of solid and liquid microspheres. PLP applications such as the driven microsatellite, target surface particle removal, and orbital debris removal are also discussed. Although the PLP has been applied to a variety of fields, further research is yet warranted to establish its application in the aerospace field.

The initial goal of occupational reproductive health research is to effectively study the many toxicants, physical agents, and biomechanical and psychosocial stressors that may constitute reproductive hazards in the workplace. Although the main objective of occupational reproductive researchers and clinicians is to prevent recognized adverse reproductive outcomes, research has expanded to include a broader spectrum of chronic health outcomes potentially affected by reproductive toxicants. To aid in achieving these goals, the National Institute for Occupational Safety and Health, along with its university, federal, industry, and labor colleagues, formed the National Occupational Research Agenda (NORA) in 1996. NORA resulted in 21 research teams, including the Reproductive Health Research Team (RHRT). In this report, we describe progress made in the last decade by the RHRT and by others in this field, including prioritizing reproductive toxicants for further study; facilitating collaboration among epidemiologists, biologists, and toxicologists; promoting quality exposure assessment in field studies and surveillance; and encouraging the design and conduct of priority occupational reproductive studies. We also describe new tools for screening reproductive toxicants and for analyzing mode of action. We recommend considering outcomes such as menopause and latent adverse effects for further study, as well as including exposures such as shift work and nanomaterials. We describe a broad domain of scholarship activities where a cohesive system of organized and aligned work activities integrates 10 years of team efforts and provides guidance for future research.

Short- and Long-Term Outcomes of Student Field Research Experiences in Special Populations.

PubMed

Soliman, Amr S; Chamberlain, Robert M

2016-06-01

Global health education and training of biomedical students in international and minority health research is expending through U.S. academic institutions. This study addresses the short- and long-term outcomes of an NCI-funded R25 short-term summer field research training program. This program is designed for MPH and Ph.D. students in cancer epidemiology and related disciplines, in international and minority settings (special populations) in a recent 7-year period. Positive short-term outcome of 73 students was measured as publishing a manuscript from the field research data and having a job in special populations. Positive long-term outcome was measured as having a post-doc position, being in a doctoral program, and/or employment in special populations at least 3 years from finishing the program. Significant factors associated with both short- and long-term success included resourcefulness of the student and compatibility of personalities and interests between the student and the on-campus and off-campus mentors. Short-term-success of students who conducted international filed research was associated with visits of the on-campus mentor to the field site. Short-term success was also associated with extent of mentorship in the field site and with long-term success. Future studies should investigate how field research sites could enhance careers of students, appropriateness of the sites for specific training competencies, and how to maximize the learning experience of students in international and minority research sites.

PubMed

Gough, Brendan; Lyons, Antonia

2016-06-01

In this paper we reflect on current trends and anticipate future prospects regarding qualitative research in Psychology. We highlight various institutional and disciplinary obstacles to qualitative research diversity, complexity and quality. At the same time, we note some causes for optimism, including publication breakthroughs and vitality within the field. The paper is structured into three main sections which consider: 1) the positioning of qualitative research within Psychology; 2) celebrating the different kinds of knowledge produced by qualitative research; and 3) implementing high quality qualitative research. In general we accentuate the positive, recognising and illustrating innovative qualitative research practices which generate new insights and propel the field forward. We conclude by emphasising the importance of research training: for qualitative research to flourish within Psychology (and beyond), students and early career researchers require more sophisticated, in-depth instruction than is currently offered.

PubMed

Niehaus, William N; Silver, Julie K; Katz, Matthew S

2018-05-01

Implementation science is an evolving part of translating evidence into clinical practice and public health policy. This report describes how a social media strategy for the journal PM&R using metrics, including alternative metrics, contributes to the dissemination of research and other information in the field of physical medicine and rehabilitation. The primary goal of the strategy was to disseminate information about rehabilitation medicine, including but not limited to new research published in the journal, to health care professionals. Several different types of metrics were studied, including alternative metrics that are increasingly being used to demonstrate impact in academic medicine. A secondary goal was to encourage diversity and inclusion of the physiatric workforce-enhancing the reputations of all physiatrists by highlighting their research, lectures, awards, and other accomplishments with attention to those who may be underrepresented. A third goal was to educate the public so that they are more aware of the field and how to access care. This report describes the early results following initiation of PM&R's coordinated social media strategy. Through a network of social media efforts that are strategically integrated, physiatrists and their associated institutions have an opportunity to advance their research and clinical agendas, support the diverse physiatric workforce, and educate the public about the field to enhance patient awareness and access to care.

For the past three years the University of Maine Cooperative Extension 4-H has connected K-12 students in Maine and around the country to UMaine researchers in the field as part of its Follow a Researcher (FAR) Program™. This program aims to provide middle and high school students with a look into future science career paths. FAR™ selects one student engaged in university level research per year to showcase their work. Previous years have selected graduate students with field-work intensive research. During the graduate student's field expedition, a weekly education science video is released based on the Next Generation Science Standards. Similarly, classroom students are encouraged to ask questions during weekly Twitter session hosted live from the field. Past expeditions have taken students to the Quelccaya Ice Cap in Peru as well as the Falkland Islands. This year's expedition shared graduate student Lynn Kaluzienski's expedition to the Ross Ice Shelf in Antarctica. Highlights include obtaining GPS observations in a remote setting using helicopter support, as well acquiring scientific measurements from a heavily crevassed area through the use of robotically towed ground penetrating radar (GPR). Future program plans include connecting K-12 students with graduate students with a focus in lab-intensive research as well as engineering. We also are developing a training program for university outreach staff and a Follow a Researcher™ network that would allow other universities to host their own program while tapping into a larger national K-12 audience.

PubMed

Cardona, Genís; Sanz, Joan P

2015-01-01

To determine the main current research interests of scientists working in the contact lens field. All articles published in the 2011 issues of all journals included in the Journal Citation Reports subject category Ophthalmology were inspected to expose those papers related to the contact lens field. Information regarding source journal was obtained and authorship details were recorded to determine the top most prolific authors, institutions and countries. A comprehensive list of key words was compiled to generate a two-dimensional term map in which the frequency of occurrence of a particular term is defined by label size and the distance between two terms is an indication of the relatedness of these terms, based on their co-occurrences within groups of key words. Clusters of related terms were also identified. Visual examination of all articles uncovered a total of 156 papers, published in 28 different journals. Contact Lens & Anterior Eye, Eye & Contact Lens and Optometry and Vision Science had 27 articles each. The most prolific authors and institutions revealed the predominance of countries with long research tradition in the contact lens field. Ten different word clusters or areas of interest were identified, including both traditional, yet unresolved issues (e.g., comfort or dry eye), and the latest research efforts (e.g., myopia control). These findings, which revealed contact lenses to be a fertile area of research, may be of relevance to new researchers as well as to those interested in exploring the latest research trends in this scientific discipline.

Research on Extrusion of Rubber Composites Reinforced by Short Fibers Orientation Based on FEA

NASA Astrophysics Data System (ADS)

Zhang, Dewei; Wang, Chuansheng; Shen, Bo; Li, Shaoming; Bian, Huiguang

2018-06-01

In recent years, rubber composites reinforced by short fibers has been researched deeply, because of its good performances such as higher wear resistance, higher cut resistance and so on. Some research results indicated that if short fibers get orientation in rubber composites, the performances of rubber products could be promoted greatly. But how to make short fibers get orientation in rubber matrix during extrusion is still a real problem. And there are many parameters affect the short fibers orientation. So, in this paper, the effects of die structure including expansion-die and dam-expansion-die on extrusion flow field of short fiber and rubber composite material during extrusion process has been researched by Polyflow. And the FEA results about the pressure field, velocity field and the velocity vector of the rubber composites flow field indicate that, comparing with expansion-die and the dam-expansion-die, the latter one is better for the extrusion process of rubber composites and making short fibers get radial orientation in rubber matrix.

There was a conscious effort to stimulate lively discussion about the key issues in the field today. Time for formal presentations was limited in the interest of group discussions. In order that more scientists could communicate their most recent results, poster presentation time was scheduled. A copy of the formal schedule and speaker program and the poster program is included. In addition to these formal interactions, "free time" was scheduled to allow informal discussions. Such discussions are fostering new collaborations and joint efforts in the field.

Evolutionary ethnobiology and cultural evolution: opportunities for research and dialog.

PubMed

Santoro, Flávia Rosa; Nascimento, André Luiz Borba; Soldati, Gustavo Taboada; Ferreira Júnior, Washington Soares; Albuquerque, Ulysses Paulino

2018-01-09

The interest in theoretical frameworks that improve our understanding of social-ecological systems is growing within the field of ethnobiology. Several evolutionary questions may underlie the relationships between people and the natural resources that are investigated in this field. A new branch of research, known as evolutionary ethnobiology (EE), focuses on these questions and has recently been formally conceptualized. The field of cultural evolution (CE) has significantly contributed to the development of this new field, and it has introduced the Darwinian concepts of variation, competition, and heredity to studies that focus on the dynamics of local knowledge. In this article, we introduce CE as an important theoretical framework for evolutionary ethnobiological research. We present the basic concepts and assumptions of CE, along with the adjustments that are necessary for its application in EE. We discuss different ethnobiological studies in the context of this new framework and the new opportunities for research that exist in this area. We also propose a dialog that includes our findings in the context of cultural evolution.

Genomics Research: World Survey of Public Funding

PubMed Central

Pohlhaus, Jennifer Reineke; Cook-Deegan, Robert M

2008-01-01

Background Over the past two decades, genomics has evolved as a scientific research discipline. Genomics research was fueled initially by government and nonprofit funding sources, later augmented by private research and development (R&D) funding. Citizens and taxpayers of many countries have funded much of the research, and have expectations about access to the resulting information and knowledge. While access to knowledge gained from all publicly funded research is desired, access is especially important for fields that have broad social impact and stimulate public dialogue. Genomics is one such field, where public concerns are raised for reasons such as health care and insurance implications, as well as personal and ancestral identification. Thus, genomics has grown rapidly as a field, and attracts considerable interest. Results One way to study the growth of a field of research is to examine its funding. This study focuses on public funding of genomics research, identifying and collecting data from major government and nonprofit organizations around the world, and updating previous estimates of world genomics research funding, including information about geographical origins. We initially identified 89 publicly funded organizations; we requested information about each organization's funding of genomics research. Of these organizations, 48 responded and 34 reported genomics research expenditures (of those that responded but did not supply information, some did not fund such research, others could not quantify it). The figures reported here include all the largest funders and we estimate that we have accounted for most of the genomics research funding from government and nonprofit sources. Conclusion Aggregate spending on genomics research from 34 funding sources averaged around $2.9 billion in 2003 – 2006. The United States spent more than any other country on genomics research, corresponding to 35% of the overall worldwide public funding (compared to 49% US share of public health research funding for all purposes). When adjusted to genomics funding intensity, however, the United States dropped below Ireland, the United Kingdom, and Canada, as measured both by genomics research expenditure per capita and per Gross Domestic Product.

The effects of conducting authentic field-geology research on high school students' understanding of the nature of science, and their views of themselves as research scientists

NASA Astrophysics Data System (ADS)

Millette, Patricia M.

Authentic field geology research is a inquiry method that encourages students to interact more with their local environment, and by solving genuine puzzles, begin to increase their intuitive understanding of the nature and processes of science. The goal of the current study was to determine if conducting authentic field research and giving high school students the opportunity to present findings to adult audiences outside of the school setting 1) enhances students' understanding of the nature of science, and 2) affects students views of themselves as researchers. To accomplish this, ninth-grade students from a public school in northern New England engaged in a community-initiated glacial geology problem, completed a field research investigation, and presented their findings at several professional conferences. Following the completion of this student-centered field research, I investigated its effects by using a mixed methods approach consisting of qualitative and quantitative data from two sources. These included selected questions from an open-response survey (VNOS-c), and interviews that were conducted with fifteen of the students of different ages and genders. Findings show that conducting original field research seems to have a positive influence on these students' understanding of the NOS as well as the processes of science. Many of the students reported feelings of accomplishment, acceptance of responsibility for the investigation, a sense of their authentic contribution to the body of scientific knowledge in the world, and becoming scientists. This type of authentic field investigation is significant because recent reforms in earth-science education stress the importance of students learning about the nature and processes of scientific knowledge along with science content.

We present a 5-year NSF CAREER project incorporating educational outreach for high school science teachers. Teachers are integrated into field and research components of this project in order to provide the most meaningful and classroom-translatable experience. The associated research project is aimed at quantifying the strength and morphology of the Precambrian geomagnetic field via detailed paleomagnetic analyses of reliably dated mafic sequences known to contain pristine paleomagnetic records. Investigation of the geomagnetic field behavior is crucial for understanding the mechanisms of field generation, has important implications for the development of the Earth's atmosphere and biosphere, and can serve as a focus for connecting high-level Earth science research with a standard physics curriculum. Educational outreach objectives include developing effective methods for pre-college physics teachers to gain the experience and expertise to (1) use paleomagnetic research to motivate and help students understand the physics of magnetism, from microscopic to planetary scales; (2) transfer key experiences of scientific processes to classroom activities, specifically the skills of patience, innovation, flexibility, and collaboration; and (3) help students integrate mathematics and physics into logical problem-solving approaches. Because the teacher participants are directly involved with our research, they are able to provide significant contributions to project outreach and dissemination efforts. This year's work focused on sampling and analyzing mafic dikes from northern Wisconsin and Michigan. The summer phase featured a 3-week field/lab/classroom session. In week one, a 4-person field team (including two teacher participants) conducted field work - the small size of the team ensured that every participant gained skills on aspects of site location, rock identification, and paleomagnetic field procedures. During week two, participants gained proficiency at processing samples, magnetic characterization, and demagnetization experiments in an effort to characterize the orientation and strength of the Earth's magnetic field at the time of rock formation. In week three, the team analyzed data and developed classroom activities to transfer experiences to the pre-college physics classroom. Teacher researchers will work throughout the project's duration to apply and monitor the effectiveness of these efforts. During the next several years, new teams of teacher researchers will help advance this project with work in Arizona, Canada, and Minnesota, ending with a reunion of all participants back to Michigan Tech during the final year for an exchange of outcomes, both from the classroom and the university. Close collaboration with all cohorts will be maintained by participation at scientific and educational meetings, publication in research and education journals, etc. Outcomes from this outreach program will be made available to the scientific and education communities with the hope of creating an accessible and meaningful vehicle by which the intricacies of Earth magnetism can be conveyed to the next generation.

The COSPAR/ILWS roadmap on space weather published in 2015 (Advances in Space Research, 2015: DOI: 10.1016/j.asr.2015.03.023) prioritizes steps to be taken to advance understanding of space environment phenomena and to improve space weather forecasting capabilities. General recommendations include development of a comprehensive space environment specification, assessment of the state of the field on a 5-yr basis, standardization of meta-data and product metrics. To facilitate progress towards roadmap goals there is a need for a global hub for collaborative space weather capabilities assessment and development that brings together research, engineering, operational, educational, and end-user communities. The COSPAR Panel on Space Weather is aiming to build upon past progress and to facilitate coordination of established and new international space weather research and development initiatives. Keys to the success include creating flexible, collaborative, inclusive environment and engaging motivated groups and individuals committed to active participation in international multi-disciplinary teams focused on topics addressing emerging needs and challenges in the rapidly growing field of space weather. Near term focus includes comprehensive assessment of the state of the field and establishing an internationally recognized process to quantify and track progress over time, development of a global network of distributed web-based resources and interconnected interactive services required for space weather research, analysis, forecasting and education.

2018-06-01

Little has been published about the historical development of scientific evidence in the physical activity (PA) and public health research field. The study aimed to examine the evolution of knowledge in this field. A structured literature review using formal citation network analysis methods was conducted in June-2016. Using a list of influential PA publications identified by domain experts, a snowball sampling technique was used to build a compact citation network of 141 publications that represents the backbone of the field. Articles were coded by study type and research team characteristics, then analyzed by visualizing the citation network and identifying research clusters to trace the evolution of the field. The field started in the 1950s, with a health sciences focus and strong North American and European leadership. Health outcome studies appeared most frequently in the network and policy and interventions least. Critical articles on objective measurement and public policy have influenced the progress from an emphasis on health outcomes research at early stages in the field to the more recent emerging built environment and global monitoring foci. There is only modest cross-citation across types of study. To our knowledge, this paper is the first to systematically describe the development of research on PA and public health. The key publications include fundamental ideas that remain citable over time, but notable research and dissemination gaps exist and should be addressed. Increasing collaboration and communication between study areas, encouraging female researchers, and increasing studies on interventions, evaluation of interventions and policy are recommended.

From environmental to ecological ethics: toward a practical ethics for ecologists and conservationists.

PubMed

Minteer, Ben A; Collins, James P

2008-12-01

Ecological research and conservation practice frequently raise difficult and varied ethical questions for scientific investigators and managers, including duties to public welfare, nonhuman individuals (i.e., animals and plants), populations, and ecosystems. The field of environmental ethics has contributed much to the understanding of general duties and values to nature, but it has not developed the resources to address the diverse and often unique practical concerns of ecological researchers and managers in the field, lab, and conservation facility. The emerging field of "ecological ethics" is a practical or scientific ethics that offers a superior approach to the ethical dilemmas of the ecologist and conservation manager. Even though ecological ethics necessarily draws from the principles and commitments of mainstream environmental ethics, it is normatively pluralistic, including as well the frameworks of animal, research, and professional ethics. It is also methodologically pragmatic, focused on the practical problems of researchers and managers and informed by these problems in turn. The ecological ethics model offers environmental scientists and practitioners a useful analytical tool for identifying, clarifying, and harmonizing values and positions in challenging ecological research and management situations. Just as bioethics provides a critical intellectual and problem-solving service to the biomedical community, ecological ethics can help inform and improve ethical decision making in the ecology and conservation communities.

Recent Developments and Applications of the CHARMM force fields

Zhu, Xiao; Lopes, Pedro E.M.; MacKerell, Alexander D.

2011-01-01

Empirical force fields commonly used to describe the condensed phase properties of complex systems such as biological macromolecules are continuously being updated. Improvements in quantum mechanical (QM) methods used to generate target data, availability of new experimental target data, incorporation of new classes of compounds and new theoretical developments (eg. polarizable methods) make force-field development a dynamic domain of research. Accordingly, a number of improvements and extensions of the CHARMM force fields have occurred over the years. The objective of the present review is to provide an up-to-date overview of the CHARMM force fields. A limited presentation on the historical aspects of force fields will be given, including underlying methodologies and principles, along with a brief description of the strategies used for parameter development. This is followed by information on the CHARMM additive and polarizable force fields, including examples of recent applications of those force fields. PMID:23066428

Development of a towing tank PIV system and a wake survey of a marine current turbine under steady conditions

Lust, Ethan; Luznik, Luksa; Flack, Karen

2015-11-01

A submersible particle image velocimetry (PIV) system was designed and built at the U.S. Naval Academy. The system was used to study the wake of a scale-independent horizontal axis marine current turbine. The turbine is a 1/25th scale model of the U.S. National Renewable Energy Laboratory's Reference Model 1 (RM1) tidal turbine. It is a two-bladed turbine measuring 0.8 m in diameter and featuring a NACA 63-618 airfoil cross-section. The wake survey was conducted over an area extending 0.25D forward of the turbine tip path to 2.0D aft to a depth of 1.0D beneath the turbine output shaft in the streamwise plane. Each field of view was approximately 30 cm by 30 cm, and each overlapped the adjacent fields of view by 5 cm. The entire flow field was then reconstructed by registering the resultant vector fields together into a single field of investigation. Results include the field of investigation from a representative case, for the mean velocity field averaged over approximately 1,000 realizations, and turbulent statistics including turbulence intensities, Reynolds shear stresses, and turbulent kinetic energy. This research was funded by the Office of Naval Research.

Genes, race, and psychology in the genome era: an introduction.

PubMed

Anderson, Norman B; Nickerson, Kim J

2005-01-01

The mapping of the human genome has reawakened interest in the topic of race and genetics, especially the use of genetic technology to examine racial differences in complex outcomes such as health and intelligence. Advances in genomic research challenge psychology to address the myriad conceptual, methodological, and analytical issues associated with research on genetics and race. In addition, the field needs to understand the numerous social, ethical, legal, clinical, and policy implications of research in this arena. Addressing these issues should not only benefit psychology but could also serve to guide such thought in other fields, including molecular biology. The purpose of this special issue is to begin a discussion of this issue of race and genetics within the field of psychology. Several scholars who work in the fields of genetics, race, or related areas were invited to write (or had previously submitted) articles sharing their perspectives. (c) 2005 APA

Researching on the process of remote sensing video imagery

Wang, He-rao; Zheng, Xin-qi; Sun, Yi-bo; Jia, Zong-ren; Wang, He-zhan

Unmanned air vehicle remotely-sensed imagery on the low-altitude has the advantages of higher revolution, easy-shooting, real-time accessing, etc. It's been widely used in mapping , target identification, and other fields in recent years. However, because of conditional limitation, the video images are unstable, the targets move fast, and the shooting background is complex, etc., thus it is difficult to process the video images in this situation. In other fields, especially in the field of computer vision, the researches on video images are more extensive., which is very helpful for processing the remotely-sensed imagery on the low-altitude. Based on this, this paper analyzes and summarizes amounts of video image processing achievement in different fields, including research purposes, data sources, and the pros and cons of technology. Meantime, this paper explores the technology methods more suitable for low-altitude video image processing of remote sensing.

Scientific integrity: critical issues in environmental health research

PubMed Central

Merlo, Domenico Franco; Vahakangas, Kirsi; Knudsen, Lisbeth E

2008-01-01

Environmental health research is a relatively new scientific area with much interdisciplinary collaboration. Regardless of which human population is included in field studies (e.g., general population, working population, children, elderly, vulnerable sub-groups, etc.) their conduct must guarantee well acknowledged ethical principles. These principles, along with codes of conduct, are aimed at protecting study participants from research-related undesired effects and guarantee research integrity. A central role is attributed to the need for informing potential participants (i.e., recruited subjects who may be enrolled in a study), obtaining their written informed consent to participate, and making them aware of their right to refuse to participate at any time and for any reason. Data protection is also required and communication of study findings must respect participant's willingness to know or not know. This is specifically relevant for studies including biological markers and/or storing biological samples that might be analysed years later to tackle research objectives that were specified and communicated to participants at the time of recruitment or that may be formulated after consent was obtained. Integrity is central to environmental health research searching for causal relations. It requires open communication and trust and any violation (i.e., research misconduct, including fabrication or falsification of data, plagiarism, conflicting interests, etc.) may endanger the societal trust in the research community as well as jeopardize participation rates in field projects.

Bowman, Marjorie A; Lucan, Sean C; Rosenthal, Thomas C; Mainous, Arch G; James, Paul A

2017-04-01

When the new field of family medicine research began a half century ago, multiple individuals and organizations emphasized that research was a key mission. Since the field's inception, there have been notable research successes for which family medicine organizations, researchers, and leaders-assisted by federal and state governments and private foundations-can take credit. Research is a requirement for family medicine residency programs but not individual residents, and multiple family medicine departments offer research training in various forms for learners at all levels, including research fellowships. Family physicians have developed practice-based research networks (PBRNs) to conduct investigations and generate new knowledge. The field of family medicine has seen the creation of new journals to support the publication of research relevant to practicing family physicians. Nonetheless, in spite of much growth and many successes, family physicians and their research have been underrepresented in research funding. Clinical presentations in family medicine are often complex, poorly-differentiated, and exist as one of several patient complaints and diagnoses, and are not well-covered by the narrow basic-science and specialty research that defines most of the biomedical research enterprise. Overall health in the United States would benefit from a more robust research participation and greater support for family medicine research.

Electric-field sensors for bullet detection systems

NASA Astrophysics Data System (ADS)

Vinci, Stephen; Hull, David; Ghionea, Simon; Ludwig, William; Deligeorges, Socrates; Gudmundsson, Thorkell; Noras, Maciej

2014-06-01

Research and experimental trials have shown that electric-field (E-field) sensors are effective at detecting charged projectiles. E-field sensors can likely complement traditional acoustic sensors, and help provide a more robust and effective solution for bullet detection and tracking. By far, the acoustic sensor is the most prevalent technology in use today for hostile fire defeat systems due to compact size and low cost, yet they come with a number of challenges that include multipath, reverberant environments, false positives and low signal-to-noise. Studies have shown that these systems can benefit from additional sensor modalities such as E-field sensors. However, E-field sensors are a newer technology that is relatively untested beyond basic experimental trials; this technology has not been deployed in any fielded systems. The U.S. Army Research Laboratory (ARL) has conducted live-fire experiments at Aberdeen Proving Grounds (APG) to collect data from E-field sensors. Three types of E-field sensors were included in these experiments: (a) an electric potential gradiometer manufactured by Quasar Federal Systems (QFS), (b) electric charge induction, or "D-dot" sensors designed and built by the Army Research Lab (ARL), and (c) a varactor based E-field sensor prototype designed by University of North Carolina-Charlotte (UNCC). Sensors were placed in strategic locations near the bullet trajectories, and their data were recorded. We analyzed the performance of each E-field sensor type in regard to small-arms bullet detection capability. The most recent experiment in October 2013 allowed demonstration of improved versions of the varactor and D-dot sensor types. Results of new real-time analysis hardware employing detection algorithms were also tested. The algorithms were used to process the raw data streams to determine when bullet detections occurred. Performance among the sensor types and algorithm effectiveness were compared to estimates from acoustics signatures and known ground truth. Results, techniques and configurations that might work best for a given sensor platform are discussed.

The Environmental Dimensions of Migration

Hunter, Lori M.; Luna, Jessie K.; Norton, Rachel M.

2017-01-01

Research on the environmental dimensions of human migration has made important strides in recent years. However, findings have been spread across multiple disciplines with wide ranging methodologies and limited theoretical development. This article reviews key findings of the field and identifies future directions for sociological research. We contend that the field has moved beyond linear environmental “push” theories towards a greater integration of context, including micro-, meso-, and macro-level interactions. We highlight findings that migration is often a household strategy to diversify risk (NELM), interacting with household composition, individual characteristics, social networks, and historical, political and economic contexts. We highlight promising developments in the field, including the recognition that migration is a long-standing form of environmental adaptation and yet only one among many forms of adaptation. Finally, we argue that sociologists could contribute significantly to migration-environment inquiry through attention to issues of inequality, perceptions, and agency vis-à-vis structure.

Rakhmenkulova, I. F.

2014-12-01

Geology and Geophysics Department of Novosibirsk State University (GGD NSU) is famous not only because of its specific location in Academgorodok (Novosibirsk, Russia) but because of its unique traditions: - conception of permanent geology education (starting from school to scientific research for postgraduate programs) - flexible curricula allowing students to be involved in research from the second year of study - field trips covering not only famous geologic objects in Siberia (Baikal, Siberian Traps, Altay, etc.), but places all over the world. GGD students traditionally participate in the following field trips: Altay (after the first year of study), Shira (Krasnoyarsk Krai) (after the second year of study). Further field trips are real research projects and cover various places in Siberia, Russia and other countries (China, Africa, USA, Mongolia, etc.). Shira field camp is of specific interest not only because of its various geology and interesting location (it is located in the resort area surrounded by beautiful landscapes, fresh and salt lakes of various salinity) but infrastructure. This year the Top 100 Project allows the department to upgrade the camp and therefore use it not only for field trips, but for other various purposes including international conferences, research projects, geo- and ecotourism. GGD NSU is ready to be involved into research, exchange educational programs and other projects (both domestically and internationally) based on the renewed Shira field camp.

Ethnobotany as a Pharmacological Research Tool and Recent Developments in CNS-active Natural Products from Ethnobotanical Sources

McClatchey, Will C.; Mahady, Gail B.; Bennett, Bradley C.; Shiels, Laura; Savo, Valentina

2009-01-01

The science of ethnobotany is reviewed in light of its multidisciplinary contributions to natural product research for the development of pharmaceuticals and pharmacological tools. Some of the issues reviewed involve ethical and cultural perspectives of healthcare and medicinal plants. While these are not usually part of the discussion of pharmacology, cultural concerns potentially provide both challenges and insight for field and laboratory researchers. Plant evolutionary issues are also considered as they relate to development of plant chemistry and accessing this through ethnobotanical methods. The discussion includes presentation of a range of CNS-active medicinal plants that have been recently examined in the field, laboratory and/or clinic. Each of these plants is used to illustrate one or more aspects about the valuable roles of ethnobotany in pharmacological research. We conclude with consideration of mutually beneficial future collaborations between field ethnobotanists and pharmacologists. PMID:19422851

1979-01-01

Evaluation of the effects of environmental contaminants on wildlife is geared to interpreting events in the field, especially population effects, and both field and laboratory studies are planned for this purpose; procedures are adapted to specific problems and therefore do not include strict protocols or routine testing. Field evaluations include measurements of cholinesterase inhibition in brain or blood, search for dead or disabled animals, study of nesting success of birds, and general ecological observations. Residue analyses are used in evaluating organochlorine chemicals; samples may include whole bodies for determining level of exposure, brains for mortality diagnosis, whole blood for certain special studies, and eggs to help in evaluation of possible reproductive effects. Bird counts, singing-male census counts, small mammal trapping, and cage-in-field tests have proven to be ineffective or misleading and are not considered suitable for field evaluations under most circumstances. Usefulness of simulated field trials is limited to very special situations. Experimental studies that help predict and interpret field effects include determinations of lethal diagnostic levels, comparative lethal dietary toxicity tests, tests of secondary poisoning, measurement of residue loss rates, measurement of blood enzymes, tests of behavioral effects, and studies of reproductive effects.

Public perception and communication of scientific uncertainty.

PubMed

Broomell, Stephen B; Kane, Patrick Bodilly

2017-02-01

Understanding how the public perceives uncertainty in scientific research is fundamental for effective communication about research and its inevitable uncertainty. Previous work found that scientific evidence differentially influenced beliefs from individuals with different political ideologies. Evidence that threatens an individual's political ideology is perceived as more uncertain than nonthreatening evidence. The authors present 3 studies examining perceptions of scientific uncertainty more broadly by including sciences that are not politically polarizing. Study 1 develops scales measuring perceptions of scientific uncertainty. It finds (a) 3 perceptual dimensions of scientific uncertainty, with the primary dimension representing a perception of precision; (b) the precision dimension of uncertainty is strongly associated with the perceived value of a research field; and (c) differences in perceived uncertainty across political affiliations. Study 2 manipulated these dimensions, finding that Republicans were more sensitive than Democrats to descriptions of uncertainty associated with a research field (e.g., psychology). Study 3 found that these views of a research field did not extend to the evaluation of individual results produced by the field. Together, these studies show that perceptions of scientific uncertainty associated with entire research fields are valid predictors of abstract perceptions of scientific quality, benefit, and allocation of funding. Yet, they do not inform judgments about individual results. Therefore, polarization in the acceptance of specific results is not likely due to individual differences in perceived scientific uncertainty. Further, the direction of influence potentially could be reversed, such that perceived quality of scientific results could be used to influence perceptions about scientific research fields.

To perform a comparative quantitative and qualitative analysis of Chinese and non-Chinese medical ethics literature using systematic research and literature analysis in order to discern research trends in the area and provide baseline data as a reference for relevant decision making and further study. We retrieved articles using MeSH terms and keywords related to medical ethics in PubMed and CNKI, and then constructed a set of charts by applying word co-occurrence, The Pathfinder Networks algorithms, an included subject chart, a research field relationship chart, and strategy coordination charts. The total of number of papers retrieved from PubMed was six times that retrieved from CNKI. Outside China, medical ethics has been studied in eight fully shaped subject fields, including morals, ethical review, physician-patient relationships, clinical trials, euthanasia, ethics education, clinical ethics, and health policy. In contrast, medical ethics research in China is still confined to five subject fields: morals, physician-patient relations, medical ethics education, ethical review, and medical research. Medical ethics research outside China emphasizes the application of medical ethics to solve emerging problems in clinical and medical research. It is mainly centered on morals, ethical review, and physician-patient relations. By comparison, medical ethics research in China places greater emphasis on morals and medical education. In order to narrow this gap between China and other countries, we should broaden the research scope of medical ethics and add more applied research, such as ethical review and medical education. © 2012 Blackwell Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

The Specificity of Observational Studies in Physical Activity and Sports Sciences: Moving Forward in Mixed Methods Research and Proposals for Achieving Quantitative and Qualitative Symmetry

Mixed methods studies are been increasingly applied to a diversity of fields. In this paper, we discuss the growing use—and enormous potential—of mixed methods research in the field of sport and physical activity. A second aim is to contribute to strengthening the characteristics of mixed methods research by showing how systematic observation offers rigor within a flexible framework that can be applied to a wide range of situations. Observational methodology is characterized by high scientific rigor and flexibility throughout its different stages and allows the objective study of spontaneous behavior in natural settings, with no external influence. Mixed methods researchers need to take bold yet thoughtful decisions regarding both substantive and procedural issues. We present three fundamental and complementary ideas to guide researchers in this respect: we show why studies of sport and physical activity that use a mixed methods research approach should be included in the field of mixed methods research, we highlight the numerous possibilities offered by observational methodology in this field through the transformation of descriptive data into quantifiable code matrices, and we discuss possible solutions for achieving true integration of qualitative and quantitative findings.

Undergraduate students in the Geography and Biology Departments at the University of the Fraser Valley (UFV) have been provided the opportunity to participate in the time series sampling of the Fraser River at Fort Langley and Fraser Valley tributaries as part of the Global Rivers Observatory (GRO, www.globalrivers.org) which is coordinated by Woods Hole Oceanographic Institution and Woods Hole Research Center. Student research has focussed on Clayburn, Willband and Stoney Creeks that flow from Sumas Mountain northwards to the Fraser River. These watercourses are increasingly being impacted by anthropogenic activity including residential developments, industrial activity, and agricultural landuse. Students are instructed in field sampling protocols and the collection of water chemistry data and the care and maintenance of the field equipment. Students develop their own research projects and work in support of each other as teams in the field to collect the data and water samples. Students present their findings as research posters at local academic conferences and at UFV's Student Research Day. Through their involvement in our field research our students have become more aware of the state of our local streams, the methods used to monitor water chemistry and how water chemistry varies seasonally.

The Survey of Organizational Research Climate (SOuRCe) is a new instrument that assesses dimensions of research integrity climate, including ethical leadership, socialization and communication processes, and policies, procedures, structures, and processes to address risks to research integrity. We present a descriptive analysis to characterize differences on the SOuRCe scales across departments, fields of study, and status categories (faculty, postdoctoral scholars, and graduate students) for 11,455 respondents from three research-intensive universities. Among the seven SOuRCe scales, variance explained by status and fields of study ranged from 7.6% (Advisor-Advisee Relations) to 16.2% (Integrity Norms). Department accounted for greater than 50% of the variance explained for each of the SOuRCe scales, ranging from 52.6% (Regulatory Quality) to 80.3% (Integrity Inhibitors). It is feasible to implement this instrument in large university settings across a broad range of fields, department types, and individual roles within academic units. Published baseline results provide initial data for institutions using the SOuRCe who wish to compare their own research integrity climates. © The Author(s) 2014.

Current subjects on environmental mutagen research to further advance this field are described herein, and the roles of JEMS and G&E are discussed. Various important subjects are being investigated in current research fields such as severe environmental pollution in Asian countries; the identification of new hazardous substances and elucidation of mutation mechanisms using newly developed techniques; the development of new genotoxicity assays including in silico predictions using information technology and artificial intelligence as well as bioassays. International exchange by scientists is important for advancing these research fields through international conferences such as the 12th International Conference and 5th Asian Congress on Environmental Mutagens and the 7th International Workshop on Genotoxicity Testing that will be held in 2017. G&E provides a common platform for high quality environmental mutagen research, contributes to the dissemination of Asian environmental mutagen research, and potentiates the level of research being conducted.

Connections in the Field and Beyond: A Case Study of Successful Teacher Research Experiences at the Poles

NASA Astrophysics Data System (ADS)

Rosenberger, D.

2007-12-01

Successful and lasting partnerships between scientists and teachers can be established through Teacher Research Experiences (TRE). The documented benefits of the TRE include increased teacher retention in addition to renewed instructional practices in veteran teachers. The reality and excitement of field science is very difficult to convey to students if the teacher has never personally experienced it, and a TRE can transfer this interest into the classroom. With the field research experience as the centerpiece of the TRE relationship, much should be done before, during, and after the TRE to ensure a positive and lasting connection that meets the needs of both the teacher and researcher. This presentation focuses, from a teacher's first-hand perspective, on the critical issues that scientists must consider to ensure successful collaborations with teachers in the field. I have participated in two TRE's and have learned a great deal from both. In 2001, through the National Science Foundation sponsored program Teachers Experiencing Antarctica and the Arctic (TEA) I was able to participate in biochemical oceanographic science on-board the Icebreaker Oden in the Arctic Ocean. In 2005, I did biogeochemical research at Pony Lake/McMurdo Station in Antarctica as a participant in Teachers and Researchers Exploring and Collaborating (TREC), a program of the Arctic Research Consortium of the United States (ARCUS). On both research experiences, I was a working member of the science team. I was responsible for numerous teaching and outreach activities including: uploading daily journals and photos to a website, answering email from students and the public, and managing live communications with schools. Both research experiences were very successful and have resulted in lasting relationships with scientists and other teachers interested in polar science. My participation in these experiences also influenced my teaching by increasing student enthusiasm in the classroom and expanding my curriculum. It has also resulted in numerous public and school presentations. Based on these researcher experiences, I have found that are several key factors for a research experience to be successful. (1) Teachers must be prepared, open, and ready to accept a new and challenging role. (2) Teacher expectations need to be based on reality. If a teacher's expectations are different than the reality, the teacher may not be prepared to deal with a completely different set of circumstances on a daily basis. (3) Teachers should be well versed in the necessary technology skills needed for the field before deployment. This includes understanding how to operate scientific instruments as well as the technology used to convey the experience to the public. (4) Teachers need to be integrated into the science team. Assessment of his or her strengths should be done before the beginning of the actual field experience so that potential problems can be discussed and averted. Teachers also need a carefully developed schedule, however, allowing them to work with the team as well as work on their educational and outreach duties. The TRE can be a rewarding experience for both scientist and teacher, but both must be willing to work to ensure the evolution of a beneficial relationship that has impacts well beyond the field. Expectations and realities need to be discussed throughout the research experience or the experience may be a disappointment for one or both parties and the opportunity for ongoing collaboration may be impeded. Through successful TRE's and effective teacher researcher relationships, we will continue to improve science content for the present and generations of students and teachers to come.

Childhood tuberculosis contributes significantly to the global tuberculosis disease burden but remains challenging to diagnose due to inadequate methods of pathogen detection in paucibacillary pediatric samples and lack of a child-specific host biomarker to identify disease. Accurately diagnosing tuberculosis in children is required to improve case detection, surveillance, healthcare delivery, and effective advocacy. In May 2014, the National Institutes of Health convened a workshop including researchers in the field to delineate priorities to address this research gap. This blueprint describes the consensus from the workshop, identifies critical research steps to advance this field, and aims to catalyze efforts toward harmonization and collaboration in this area.

Ethical issues in field research: balancing competing values.

PubMed

O'Neill, P

1990-04-01

An ethical issue becomes a dilemma when the psychologist is pulled in different directions by competing values. This paper will focus on the conflict between experimental and ethical values inherent in field research. The problem has special significance in community psychology, which gives priority to studying, in natural settings, those affected by social problems. An example is given of research that required observation of family interaction in the homes of convicted child abusers. The case demonstrates that the value of ecological validity often conflicts with the need to protect privacy and obtain uncoerced consent. Other ethical constraints, including the duty to report lawbreaking and to protect the public from harm, may threaten research validity.

The rapid growth in data sharing presents new opportunities across the spectrum of biomedical research. Global efforts are underway to develop practical guidance for implementation of data sharing and open data resources. These include the recent recommendation of 'FAIR Data Principles', which assert that if data is to have broad scientific value, then digital representations of that data should be Findable, Accessible, Interoperable and Reusable (FAIR). The spinal cord injury (SCI) research field has a long history of collaborative initiatives that include sharing of preclinical research models and outcome measures. In addition, new tools and resources are being developed by the SCI research community to enhance opportunities for data sharing and access. With this in mind, the National Institute of Neurological Disorders and Stroke (NINDS) at the National Institutes of Health (NIH) hosted a workshop on October 5-6, 2016 in Bethesda, MD, in collaboration with the Open Data Commons for Spinal Cord Injury (ODC-SCI) titled "Preclinical SCI Data: Creating a FAIR Share Community". Workshop invitees were nominated by the workshop steering committee (co-chairs: ARF and VPL; members: AC, KDA, MSB, KF, LBJ, PGP, JMS), to bring together junior and senior level experts including preclinical and basic SCI researchers from academia and industry, data science and bioinformatics experts, investigators with expertise in other neurological disease fields, clinical researchers, members of the SCI community, and program staff representing federal and private funding agencies. The workshop and ODC-SCI efforts were sponsored by the International Spinal Research Trust (ISRT), the Rick Hansen Institute, Wings for Life, the Craig H. Neilsen Foundation and NINDS. The number of attendees was limited to ensure active participation and feedback in small groups. The goals were to examine the current landscape for data sharing in SCI research and provide a path to its future. Below are highlights from the workshop, including perspectives on the value of data sharing in SCI research, workshop participant perspectives and concerns, descriptions of existing resources and actionable directions for further engaging the SCI research community in a model that may be applicable to many other areas of neuroscience. This manuscript is intended to share these initial findings with the broader research community, and to provide talking points for continued feedback from the SCI field, as it continues to move forward in the age of data sharing.

In a drug-resistant, malaria elimination setting like Western Cambodia, field research is essential for the development of novel anti-malarial regimens and the public health solutions necessary to monitor the spread of resistance and eliminate infection. Such field studies often face a variety of similar implementation challenges, but these are rarely captured in a systematic way or used to optimize future study designs that might overcome similar challenges. Field-based research staff often have extensive experience and can provide valuable insight regarding these issues, but their perspectives and experiences are rarely documented and seldom integrated into future research protocols. This mixed-methods analysis sought to gain an understanding of the daily challenges encountered by research field staff in the artemisinin-resistant, malaria elimination setting of Western Cambodia. In doing so, this study seeks to understand how the experiences and opinions of field staff can be captured, and used to inform future study designs. Twenty-two reports from six field-based malaria studies conducted in Western Cambodia were reviewed using content analysis to identify challenges to conducting the research. Informal Interviews, Focus Group Discussions and In-depth Interviews were also conducted among field research staff. Thematic analysis of the data was undertaken using Nvivo 9 ® software. Triangulation and critical case analysis was also used. There was a lack of formalized avenues through which field workers could report challenges experienced when conducting the malaria studies. Field research staff faced significant logistical barriers to participant recruitment and data collection, including a lack of available transportation to cover long distances, and the fact that mobile and migrant populations (MMPs) are usually excluded from studies because of challenges in follow-up. Cultural barriers to communication also hindered participant recruitment and created unexpected delays. Field staff often paid a physical, emotional and financial cost, going beyond their duty in order to keep the study running. Formal monthly reports filled out by field study staff could be a key tool for capturing field study staff experiences effectively, but require specific report fields to encourage staff to outline their challenges and to propose potential solutions. Forging strong bonds with communities and their leaders may improve communication, and decrease barriers to participant recruitment. Study designs that make it feasible for MMPs to participate should be pursued; in addition to increasing the potential participant pool, this will ensure that the most malaria-endemic demographic is taken into account in research studies. Overlaps between clinical care and research create ethical dilemmas for study staff, a fact that warrants careful consideration. Lessons learned from study field staff should be used to create a set of locally-relevant recommendations to inform future study designs.

Electronic databases including the Korean Studies Information Service System (KISS), the National Assembly Library and the DBpia, HAKJISA and RISS4U for the dates 1990 to January 2014 were searched for 'meta-analysis' and 'exercise' in the fields of medical, nursing, physical therapy and physical exercise in Korea. AMSTAR was scored for quality assessment of the 33 articles included in the study. Data were analyzed using descriptive statistics, t-test, ANOVA and χ²-test. The mean score for AMSTAR evaluations was 4.18 (SD=1.78) and about 67% were classified at the low-quality level and 30% at the moderate-quality level. The scores of quality were statistically different by field of research, number of participants, number of databases, financial support and approval by IRB. The effect size that presented in individual studies were different by type of exercise in the applied intervention. This critical appraisal of meta-analysis published in various field that focused on exercise indicates that a guideline such as the PRISMA checklist should be strongly recommended for optimum reporting of meta-analysis across research fields.

Health Information Economy (HIE) is one of the broader, more complex, and challenging and yet important topics in the field of health science that requires the identification of its dimensions for planning and policy making. The aim of this study was to determine HIE concept dimensions. This paper presents a systematic methodology for analyzing the trends of HIE. For this purpose, the main keywords of this area were identified and searched in the databases and from among 4775 retrieved sources, 12 sources were studied in the field of HIE. Information Economy (IE) in the world has passed behind four paradigms that involve the information evaluation perspective, the information technology perspective, the asymmetric information perspective and information value perspective. In this research, the fourth perspective in the HIE was analyzed. The main findings of this research were categorized in three major groups, including the flow of information process in the field of health (production. collection, processing and dissemination), and information applications in the same field (education, research, health industry, policy, legislation, and decision-making) and the underlying fields. According to the findings, HIE has already developed a theoretical and conceptual gap that due to its importance in the next decade would be one of the research approaches to health science.

The Elsevier award program administered by the Editorial Board of the Journal of Quantitative Spectroscopy and Radiative Transfer (JQSRT) was conceived in June of 2006 at the 9th Electromagnetic and Light Scattering Conference in St. Petersburg, Russia. Initially the program included three annual Elsevier/JQSRT awards for exceptional early-career scientists working in the main research fields covered by JQSRT: quantitative spectroscopy, radiative transfer, and electromagnetic scattering. In June of 2010 at the 12th Electromagnetic and Light Scattering Conference in Helsinki, Finland, it was decided to expand the award program to include three biennial Elsevier awards intended to celebrate fundamental life-time achievements of internationally recognized leaders in the same research fields. Finally, in 2013 the Elsevier award program was augmented to include a fourth annual early-career award in the category of atmospheric radiation and remote sensing.

Qualitative studies. Their role in medical research.

Huston, P.; Rowan, M.

1998-01-01

OBJECTIVE: To define qualitative research in terms of its philosophical roots, the questions it addresses, its methods and analyses, and the type of results it can offer. DATA SOURCES: MEDLINE and CINAHL (Cumulative Index to Nursing and Allied Health Literature) databases were searched for the years January 1985 to April 1998. The search strategy consisted of "textword" terms that searched in the "title" field of both databases. Qualitative research and evaluation textbooks in health and the social sciences were also used. QUALITY OF EVIDENCE: The information on qualitative research is based on the most recent and valid evidence from the health and social science fields. MAIN MESSAGE: Qualitative research seeks to understand and interpret personal experience to explain social phenomena, including those related to health. It can address questions that quantitative research cannot, such as why people do not adhere to a treatment regimen or why a certain health care intervention is successful. It uses many methods of data collection, including participant observation, case studies, and interviews, and numerous approaches to data analysis that range from the quasistatistical to the intuitive and inductive. CONCLUSIONS: Qualitative research, a form of research completely different from quantitative research, can provide important insights into health-related phenomena and can enrich further research inquiries.

Research on the use of mobile technologies for alcohol use problems is a developing field. Rapid technological advances in mobile health (or mHealth) research generate both opportunities and challenges, including how to create scalable systems capable of collecting unprecedented amounts of data and conducting interventions-some in real time-while at the same time protecting the privacy and safety of research participants. Although the research literature in this area is sparse, lessons can be borrowed from other communities, such as cybersecurity or Internet security, which offer many techniques to reduce the potential risk of data breaches or tampering in mHealth. More research into measures to minimize risk to privacy and security effectively in mHealth is needed. Even so, progress in mHealth research should not stop while the field waits for perfect solutions.

Investment in plant research and development bears fruit in China.

PubMed

Chong, Kang; Xu, Zhihong

2014-04-01

Recent rapid progress in plant science and biotechnology in China demonstrates that China's stronger support for funding in plant research and development (R&D) has borne fruit. Chinese groups have contributed major advances in a range of fields, such as rice biology, plant hormone and developmental biology, genomics and evolution, plant genetics and epigenetics, as well as plant biotechnology. Strigolactone studies including those identifying its receptor and dissecting its complex structure and signaling are representative of the recent researches from China at the forefront of the field. These advances are attributable in large part to interdisciplinary studies among scientists from plant science, chemistry, bioinformatics, structural biology, and agronomy. The platforms provided by national facilities facilitate this collaboration. As well, efficient restructuring of the top-down organization of state programs and free exploration of scientists' interests have accelerated achievements by Chinese researchers. Here, we provide a general outline of China's progress in plant R&D to highlight fields in which Chinese research has made significant contributions.

Digital heritage comprises a broad variety of approaches and topics and involves researchers from multiple disciplines. While the use of digital methods in the text-oriented disciplines dealing with cultural heritage is widely discussed and canonized, an up-to-date investigation on cultural heritage as a scholarly field is currently missing. The extended abstract is about a three-stage investigation on standards, publications, disciplinary cultures as well as scholars in the field of digital heritage, carried out in 2016 and 2017. It includes results of a workshop-based survey involving 44 researchers, 15 qualitative interviews as well as an online survey with nearly 1000 participants. As an overall finding, a community is driven by researchers from European countries and especially Italy with a background in humanities, dealing with topics of data acquisition, data management and visualization. Moreover, conference series are most relevant for a scientific discourse, and especially EU projects set pace as most important research endeavours.

Synthesis on biological soil crust research

2016-01-01

In this closing chapter, we summarize the advances in biocrust research made during the last 1.5 decades. In the first part of the chapter, we discuss how in some research fields, such as the microbial diversity of fungi, bacteria, and microfauna; the interaction between biocrusts and vascular plants; and in the rehabilitation of biocrusts; particularly large achievements have been made. In other fields, previously established knowledge of overall patterns has been corroborated and refined by additional studies, e.g., in the fields of soil stabilization and disturbance effects. In the second part of the chapter, we outline the research gaps and challenges foreseen by us. We identify multiple knowledge gaps, including many understudied geographic regions, the largely missing link between genetic and morphological species identification data, and the answers to some mechanistic questions, such as the overall role of biocrusts in hydrology and nutrient cycles. With some ideas on promising new research questions and approaches we close this chapter and the overall book.

As employees of Polar Field Services/VPR, the arctic logistics provider to the US National Science Foundation, we bear witness to the exploration, documentation, and celebration of the International Polar Year (IPY). Our front- row vantage point (logisticians working with field scientists) offers us a rare opportunity to report on developments at the frontiers of polar research and to describe how scientists work in the Arctic. Our reporting mechanism is field notes, a weekly (summer) to monthly (winter) electronic digest of information about the IPY research we support. Each issue showcases a short "cover" piece highlighting science projects or profiling arctic program participants. In addition, field notes offers news updates, short interviews, and blog-style dispatches contributed by researchers and support personnel. Wherever possible, we include URLs so readers may find more information via the Web: we link to an online database of projects we maintain for the NSF, to university Web sites, project blogs, and so on. We aim to inform the interested layperson about the myriad of activity in the IPY. We like to show that arctic science is interesting, relevant--and a great adventure. We've found field notes to be an excellent outreach venue. By no means a slick media outlet, field notes is published "on the side" by a small but dedicated group of employees who are endlessly fascinated by, and who enjoy an engaging perspective on, contemporary arctic research.

A problem with inclusion in learning disability research.

PubMed

McClimens, Alex; Allmark, Peter

2011-09-01

People with severe learning disability are particularly difficult to include in the research process. As a result, researchers may be tempted to focus on those with learning disability who can be included. The problem is exacerbated in this field as the political agenda of inclusion and involvement is driven by those people with learning disability who are the higher functioning. To overcome this we should first detach the notion of consent from ideas about autonomy and think instead of it as a way to avoid wronging others; this fits the original historical use of consent in research. This allows us to think in terms of including participants to the best of their abilities rather than in terms of a threshold of autonomy. Researchers could then use imaginative ways to include the least able and to ensure they are not wronged in research or by exclusion from it.

Laboratory for Extraterrestrial Physics

Vondrak, Richard R. (Technical Monitor)

2001-01-01

The NASA Goddard Space Flight Center (GSFC) Laboratory for Extraterrestrial Physics (LEP) performs experimental and theoretical research on the heliosphere, the interstellar medium, and the magnetospheres and upper atmospheres of the planets, including Earth. LEP space scientists investigate the structure and dynamics of the magnetospheres of the planets including Earth. Their research programs encompass the magnetic fields intrinsic to many planetary bodies as well as their charged-particle environments and plasma-wave emissions. The LEP also conducts research into the nature of planetary ionospheres and their coupling to both the upper atmospheres and their magnetospheres. Finally, the LEP carries out a broad-based research program in heliospheric physics covering the origins of the solar wind, its propagation outward through the solar system all the way to its termination where it encounters the local interstellar medium. Special emphasis is placed on the study of solar coronal mass ejections (CME's), shock waves, and the structure and properties of the fast and slow solar wind. LEP planetary scientists study the chemistry and physics of planetary stratospheres and tropospheres and of solar system bodies including meteorites, asteroids, comets, and planets. The LEP conducts a focused program in astronomy, particularly in the infrared and in short as well as very long radio wavelengths. We also perform an extensive program of laboratory research, including spectroscopy and physical chemistry related to astronomical objects. The Laboratory proposes, develops, fabricates, and integrates experiments on Earth-orbiting, planetary, and heliospheric spacecraft to measure the characteristics of planetary atmospheres and magnetic fields, and electromagnetic fields and plasmas in space. We design and develop spectrometric instrumentation for continuum and spectral line observations in the x-ray, gamma-ray, infrared, and radio regimes; these are flown on spacecraft to study the interplanetary medium, asteroids, comets, and planets. Suborbital sounding rockets and groundbased observing platforms form an integral part of these research activities. This report covers the period from approximately October 1999 through September 2000.

Undergraduate and graduate education in Volcanology at University of Bristol, UK

NASA Astrophysics Data System (ADS)

Ernst, G.; Mader, H.; Phillips, J.; Lejeune, A.; Sparks, S.

2002-05-01

Volcanology education at Bristol is unique for several reasons. The Bristol group operates within a University Research Centre in Environmental and Geophysical Flows (CEGF), involving over 30 staff-to-PhD-level researchers, centered around close collaboration between 4 depts including Earth Sciences and Applied Maths. The uniquely-multidisciplinary setting supports training in volcanology with strong emphasis on combining field-based physical volcanology, theoretical modelling and simple analogue lab experiments. PhD students gain expertise in at least 2 of these 3 aspects during the PhD. Our dept itself is one of the most multidisciplinary in Earth Sciences and is ranked among the 3 leading ES Depts for its research quality. At dept level, there is a strong focus on understanding physical and chemical processes of magmatic/volcanic systems. Teaching/training of students is thus supported by excellent research, and aims at providing profound insights and practical experience into research. At undergraduate level, key experiences of students include 1.) a week-long field class to textbook-quality field sections on one of the most studied active volcanoes (Santorini, Greece), 2.) an independent project where the aim is to learn about all aspects of research as part of a well-focused study including gaining the experience of producing one potentially-publishable paper, 3.) a hands-on research project centered on using the latest analytical methods to solve a problem - this is most successful for 2 reasons: a.) Bristol hosts the EU Geochemical Facility and coordinates an EU Marie Curie Training Centre and b.) the students operate the instruments themselves (ie. they are not run for them); 4.) fourth-year students are especially challenged on the quantitative front (computer programming, statistical data analyses and hypothesis testing -we have excellent computer labs support for teaching), advanced field work and several independent projects. Students are helped into gaining volcanology summer experience immediately prior to dissertation work and those involved tend to progress much quicker as young researchers. At all levels, providing insights into the research process is through giving much freedom to develop as independent scientists as well as much contact time to discuss research results. Steve Sparks has also recently developed two educational video films: one for 12-16 year olds and another as support for undergraduate teaching - both providing insights into active volcanoes, volcanic processes and hazards, research and monitoring. Volcanology training is also through a Bristol-coordinated EU Training Network where EU PhD/postdocs spend 6-15 months in a EU leading volcanology group, one of which is Bristol, and 3 months in a Volcano Observatory. Factors that enhance the quality of the learning/training experience in volcanology are multiple. A pre-requisite to effective learning at any level isthe development of a strong connection between student and mentor/teacher -this is achieved best through field work, supervision/tutorial contact time, practical classes and our general approach to teaching. Approach to teaching includes extraordinary enthusiasm for volcanology, teaching by-example (eg. in the field), fostering critical thinking and questioning in students (Socratic approach), fostering class interactions, challenging students into producing highest-quality of work and trusting that they can achieve it, and providing as much hands-on experience as possible.

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

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.

Over the years, a coherent research strategy has developed in the field of stellar physics at the Institute of Astronomy and Astrophysics (IAA). It involves observational studies (chemical composition of giant stars, binary properties, tomography of stellar atmospheres) that make use of the large ESO telescopes as well as of other major instruments. The presence of a high-resolution spectrograph on the 3.6-m Devasthal Optical Telescope (DOT) would therefore be highly beneficial to IAA research. These observations are complemented and supported by theoretical studies of mass transfer in binary systems, of standard and non-standard stellar evolution (including the modelling of stellar hydrodynamical nuclear burning for application to certain thermonuclear supernovae) and of nuclear astrophysics (a field in which IAA has been recognized for a long time as an international centre of excellence), including the theory of nucleosynthesis. IAA also addresses the end-points of stellar evolution as it is carrying out research on the compact remnants of stellar evolution of massive stars: neutron stars.

2015-09-01

Ordinal logistic regression is a statistical technique that can be used to describe the relationship between ordinal response variable with one or more independent variables. This method has been used in various fields including in the health field. In this research, ordinal logistic regression is used to describe the relationship between nutritional status of children with age, gender, height, and family status. Nutritional status of children in this research is divided into over nutrition, well nutrition, less nutrition, and malnutrition. The purpose for this research is to describe the characteristics of children in the KarangKitri Village and to determine the factors that influence the nutritional status of children in the KarangKitri village. There are three things that obtained from this research. First, there are still children who are not categorized as well nutritional status. Second, there are children who come from sufficient economic level which include in not normal status. Third, the factors that affect the nutritional level of children are age, family status, and height.

2015-12-01

The unique geo-environment offered in Capitol Reef National Park and its surrounding areas has a long-standing history of inspiring geological scientific exploration. The Capitol Reef Field Station was established in 2008 as part of collaboration between the National Park and Utah Valley University in order to support teaching and research of the natural environment found within the park and on the Colorado Plateau. The facility itself situated deep within the park, well off any public road system offers state of the art alternative energy and sustainable construction and makes extensive use of passive heating and cooling, in order to maintain its status of being "off-grid." The field station is a 6200 square foot complex of classrooms and dormitories supporting university level education and field studies of the Colorado Plateau. The complex includes a classroom and dining area, professional kitchen, and two separate dormitories, which can sleep up to 24 overnight visitors, while the daytime usage can accommodate up to 40 visitors. The vision of the facility is to support teaching and research toward responsible, respectful, and sustainable stewardship of the natural world - including Interdisciplinary learning between arts and sciences Student internships and service learning in collaboration with the National Park Service Field-based scientific research (as well as inventorying and assessing Park ecosystems changes) Field training in scientific research Collaboration between National Park Service scientists and local, regional, and national institutions The park is situated at 38°N 249°E at elevations greater than 2000 m in Southern Utah. In contrast to the more famous neighboring sister parks such as Zion and Bryce Canyon National Parks, which are in relatively close proximity to large road systems and cities, Capitol Reef offers what is believed to be the darkest night sky in the US. The culmination of features creates an ideal location for studies of the faint upper atmospheric airglow emissions. This presentation details the upper atmospheric undergraduate educational program at UVU, and will also include a section regarding the newly established interdisciplinary air pollution educational program, and how communities outside of UVU can use the facility.

Integration of the Belarusian Space Research Potential Into International University Nanosatellite Programm

NASA Astrophysics Data System (ADS)

Saetchnikov, Vladimir; Ablameyko, Sergey; Ponariadov, Vladimir

Belarus has inherited a significant space research potential created back in the Soviet era. It is one of the countries in the world capable of research, engineering and production across a wide range of space technologies, such as remote sensing systems, satellite telecommunication systems and positioning systems etc. Despite these strengths, the participation of Belarusian space organizations in the UN space activity and International research programs is very low. Belarusian State University (BSU) is the leading research and high school education organization of Belarus in several fields of research and development. It was deeply involved into various space research projects, including Soviet Lunar Program, Space Station “Mir”, Space Shuttle “Buran”. From 2004, when the national space programs were restarted, branches of BSU like Institute of Physics and Aerospace Technologies (IPAT), Center for aerospace education, Research laboratory of applied space technologies are leading the research and development works in the field of space communication systems, Earth observation tools and technologies, electronic and optic sensors, etc. The mail fields of activity are: • Hard and software development for small satellites and university satellites in particular. • Development of sensor satellite systems. • Small satellite research experiments (biological and medical in particular). • Earth, airplane and satellite remote monitoring systems including hard and software. • Early warning ecological and industrial Systems. • Geographic information systems of several natural and industrial areas. • Climate change investigation. We have partners from several universities and research institutes from Russian Federation, Ukraine, Kazakhstan and Germany etc. We have a ground station to receive satellite data in RF L and X bands and are very interested to be incorporated into international remote monitoring network. This activity can be combined with astrometry and ballistic data processing. Next point is university satellite. We are developing now several modules for education: data acquisition, telemetry, communication systems and also are very interested to cooperate in this field with international partners. Space Research is certainly a “high end” of any science system such as material sciences and engineering, applied mathematics, cybernetics, ICT, radio physics, electronics, etc. Moreover, space research capacities enable cutting edge research works in such areas as Environment (e.g. Earth observation), Biotechnologies, Health, New Materials, etc. Progress in integrating Belarusian Space Research potential into international society will serve as a catalyst and enabler for all critically important scientific and technological fields to advance on the way of development and global integration.

Livestock phenotypes are determined by the interaction of a variety of factors, including the genome, the epigenome and the environment. Epigenetics refers to gene expression changes without DNA sequence alterations. Epigenetic markers mainly include DNA methylation, histone modifications, non-coding RNAs, and imprinting genes. More and more researches show that epigenetic markers play an important role in the traits of pigs by modulating phenotype changes via gene expression. However, the role of epigenetic markers has caught little attention in swine breeding. The mechanism that influences important traits of swine has not been analyzed in detail, and it still lacks adequate scientific basis for practical applications. From the aspects of nutrition, diseases, important economic traits and trans-generational inheritance, we summarize the research, application prospects and challenges in the field of utilizing epigenetic markers in molecular breeding of pigs, thus providing a more comprehensive theoretical basis to promote more rapid research development in this field.

2003-04-01

With the completion of scientific studies undertaken as part of the 1998 Mallik 2L-38 gas hydrate research well, an international research site was established for the study of Arctic natural gas hydrates in the Mackenzie Delta of northwestern Canada. Quantitative well log analysis and core studies reveal multiple gas hydrate layers from 890 m to 1106 m depth, exceeding 110 m in total thickness. High gas hydrate saturation values, which in some cases exceed 80% of the pore volume, establish the Mallik gas hydrate field as one of the most concentrated gas hydrate reservoirs in the world. Beginning in December 2001 and continuing to the middle of March 2002, two 1188 m deep science observation wells were drilled and instrumented and a 1166 m deep production research well program was carried out. The program participants include 8 partners; The Geological Survey of Canada (GSC), The Japan National Oil Corporation (JNOC), GeoForschungsZentrum Potsdam (GFZ), United States Geological Survey (USGS), United States Department of the Energy (USDOE), India Ministry of Petroleum and Natural Gas (MOPNG)/Gas Authority of India (GAIL) and the Chevron-BP-Burlington joint venture group. In addition the project has been accepted as part of the International Scientific Continental Drilling Program. The Geological Survey of Canada is coordinating the science program for the project and JAPEX Canada Ltd. acted as the designated operator for the fieldwork. Primary objectives of the research program are to advance fundamental geological, geophysical and geochemical studies of the Mallik gas hydrate field and to undertake advanced production testing of a concentrated gas hydrate reservoir. Full-scale field experiments in the production well monitored the physical behavior of the hydrate deposits in response to depressurization and thermal stimulation. The observation wells facilitated cross-hole tomography and vertical seismic profile experiments (before and after production) as well as the measurement of in situ formation conditions. A wide- ranging science and engineering research program included the collection of gas-hydrate-bearing core samples and downhole geophysical logging. Laboratory and modeling studies undertaken during the field program, and subsequently as part of a post-field research program, will document the sedimentology, physical/petrophysical properties, geochemistry, geophysics, reservoir characteristics and production behavior of the Mallik gas hydrate accumulation. The research team, including some 100 participant scientists from over 20 institutes in 7 countries, expects to publish the scientific results in 2004.

Organic functional materials, including conjugated molecules and fluorescent dyes, have been rapidly developed in recent years because they can be applied in many fields, such as solar cells, biosensing and bioimaging, and medical adjuvant therapy. Organic functional materials with aggregation-induced emission or aggregation-enhanced emission (AIE/AEE) characteristics have increasingly attracted attention due to their high quantum efficiency in the aggregated or solid state. A large variety of AIE/AEE materials have been designed and applied during the exponential growth of research interest in the abovementioned fields. Multiphenyl-substituted 1,3-butadiene (MPB), as a core structure that includes tetraphenyl-1,3-butadiene, hexaphenyl-1,3-butadiene and their derivatives, show a typical AIE/AEE feature and can be potentially used in all the abovementioned fields. This review summarizes the design principles, the corresponding syntheses, and the structure-property relationships of MPBs, as well as their excellent innovative functionalities and applications. This review will be very useful for scientists conducting chemistry, materials, and biomedical research in AIE/AEE-related fields. © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Synthetic biology and occupational risk.

Howard, John; Murashov, Vladimir; Schulte, Paul

2017-03-01

Synthetic biology is an emerging interdisciplinary field of biotechnology that involves applying the principles of engineering and chemical design to biological systems. Biosafety professionals have done an excellent job in addressing research laboratory safety as synthetic biology and gene editing have emerged from the larger field of biotechnology. Despite these efforts, risks posed by synthetic biology are of increasing concern as research procedures scale up to industrial processes in the larger bioeconomy. A greater number and variety of workers will be exposed to commercial synthetic biology risks in the future, including risks to a variety of workers from the use of lentiviral vectors as gene transfer devices. There is a need to review and enhance current protection measures in the field of synthetic biology, whether in experimental laboratories where new advances are being researched, in health care settings where treatments using viral vectors as gene delivery systems are increasingly being used, or in the industrial bioeconomy. Enhanced worker protection measures should include increased injury and illness surveillance of the synthetic biology workforce; proactive risk assessment and management of synthetic biology products; research on the relative effectiveness of extrinsic and intrinsic biocontainment methods; specific safety guidance for synthetic biology industrial processes; determination of appropriate medical mitigation measures for lentiviral vector exposure incidents; and greater awareness and involvement in synthetic biology safety by the general occupational safety and health community as well as by government occupational safety and health research and regulatory agencies.

Road traffic injuries account for 1.3 million deaths per year world-wide. Mitigating both fatalities and injuries requires a detailed understanding of the tolerance of the human body to external load. To identify research priorities, it is necessary to periodically compare trends in injury tolerance research to the characteristics of injuries occurring in the field. This study sought to perform a systematic review on the last twenty years of experimental injury tolerance research, and to evaluate those results relative to available epidemiologic data. Four hundred and eight experimental injury tolerance studies from 1990-2009 were identified from a reference index of over 68,000 papers. Examined variables included the body regions, ages, and genders studied; and the experimental models used. Most (20%) of the publications studied injury to the spine. There has also been a substantial volume of biomechanical research focused on upper and lower extremity injury, thoracic injury, and injury to the elderly - although these injury types still occur with regularity in the field. In contrast, information on pediatric injury and physiological injury (especially in the central nervous system) remains lacking. Given their frequency of injury in the field, future efforts should also include improving our understanding of tolerances and protection of vulnerable road users (e.g., motorcyclists, pedestrians).

Case studies within a mixed methods paradigm: toward a resolution of the alienation between researcher and practitioner in psychotherapy research.

PubMed

Dattilio, Frank M; Edwards, David J A; Fishman, Daniel B

2010-12-01

This article addresses the long-standing divide between researchers and practitioners in the field of psychotherapy, regarding what really works in treatment and the extent to which interventions should be governed by outcomes generated in a "laboratory atmosphere." This alienation has its roots in a positivist paradigm, which is epistemologically incomplete because it fails to provide for context-based practical knowledge. In other fields of evaluation research, it has been superseded by a mixed methods paradigm, which embraces pragmatism and multiplicity. On the basis of this paradigm, we propose and illustrate new scientific standards for research on the evaluation of psychotherapeutic treatments. These include the requirement that projects should comprise several parallel studies that involve randomized controlled trials, qualitative examinations of the implementation of treatment programs, and systematic case studies. The uniqueness of this article is that it contributes a guideline for involving a set of complementary publications, including a review that offers an overall synthesis of the findings from different methodological approaches.

Ali, Nancy; May, Stephen; Grafton, Kate

2018-05-23

This systematic review aimed at appraising the methodological rigor of grounded theory research published in the field of physiotherapy to assess how the methodology is understood and applied. A secondary aim was to provide research implications drawn from the findings to guide future grounded theory methodology (GTM) research. A systematic search was conducted in MEDLINE, CINHAL, SPORT Discus, Science Direct, PubMed, Scopus, and Web of Science to identify studies in the field of physiotherapy that reported using GTM and/or methods in the study title and/or abstract. The descriptive characteristics and methodological quality of eligible studies were examined using grounded theory methodology assessment guidelines. The review included 68 studies conducted between 1998 and 2017. The findings showed that GTM is becoming increasingly used by physiotherapy researchers. Thirty-six studies (53%) demonstrated a good understanding and appropriate application of GTM. Thirty-two studies (47%) presented descriptive findings and were considered to be of poor methodological quality. There are several key tenets of GTM that are integral to the iterative process of qualitative theorizing and need to be applied throughout all research practices including sampling, data collection, and analysis.

In recent years, the literature associated with healthcare big data has grown rapidly, but few studies have used bibliometrics and a visualization approach to conduct deep mining and reveal a panorama of the healthcare big data field. To explore the foundational knowledge and research hotspots of big data research in the field of healthcare informatics, this study conducted a series of bibliometric analyses on the related literature, including papers' production trends in the field and the trend of each paper's co-author number, the distribution of core institutions and countries, the core literature distribution, the related information of prolific authors and innovation paths in the field, a keyword co-occurrence analysis, and research hotspots and trends for the future. By conducting a literature content analysis and structure analysis, we found the following: (a) In the early stage, researchers from the United States, the People's Republic of China, the United Kingdom, and Germany made the most contributions to the literature associated with healthcare big data research and the innovation path in this field. (b) The innovation path in healthcare big data consists of three stages: the disease early detection, diagnosis, treatment, and prognosis phase, the life and health promotion phase, and the nursing phase. (c) Research hotspots are mainly concentrated in three dimensions: the disease dimension (e.g., epidemiology, breast cancer, obesity, and diabetes), the technical dimension (e.g., data mining and machine learning), and the health service dimension (e.g., customized service and elderly nursing). This study will provide scholars in the healthcare informatics community with panoramic knowledge of healthcare big data research, as well as research hotspots and future research directions.

Focus on the Rashba effect

NASA Astrophysics Data System (ADS)

Bihlmayer, G.; Rader, O.; Winkler, R.

2015-05-01

The Rashba effect, discovered in 1959, continues to supply fertile ground for fundamental research and applications. It provided the basis for the proposal of the spin transistor by Datta and Das in 1990, which has largely inspired the broad and dynamic field of spintronics. More recent developments include new materials for the Rashba effect such as metal surfaces, interfaces and bulk materials. It has also given rise to new phenomena such as spin currents and the spin Hall effect, including its quantized version, which has led to the very active field of topological insulators. The Rashba effect plays a crucial role in yet more exotic fields of physics such as the search for Majorana fermions at semiconductor-superconductor interfaces and the interaction of ultracold atomic Bose and Fermi gases. Advances in our understanding of Rashba-type spin-orbit couplings, both qualitatively and quantitatively, can be obtained in many different ways. This focus issue brings together the wide range of research activities on Rashba physics to further promote the development of our physical pictures and concepts in this field. The present Editorial gives a brief account on the history of the Rashba effect including material that was previously not easily accessible before summarizing the key results of the present focus issue as a guidance to the reader.

Co-Citation Analysis of Articles Published in Substance Abuse Journals: Intellectual Structure and Research Fields (2001-2012).

The purpose of this study is to introduce a new methodology in the field of substance abuse, namely, co-citation analysis, which uses the bibliographic references of publications to establish the main thematic areas being researched and to identify the seminal documents that have contributed to establishing the intellectual foundation of the discipline at the present time. We identified all bibliographic references that were cited in documents published in the substance abuse journals included in the Journal Citation Reports in the 2001-2012 period, generating a co-citation matrix. This matrix was used to perform a co-citation network analysis. The co-citation network analysis led to the identification of 56 prominent research clusters that bring together 698 documents; their subject matter constitutes the foundation of the discipline in the field's journals. Substance abuse research is dominated by a few core topics; chief among them are tools for measuring and diagnosing dependence, as well as therapeutic approaches to treat alcohol abuse and nicotine addiction. Other areas of note include epidemiological studies, research on drug user motivation (particularly among young people), binge drinking, social support mediators and networks, opioid dependence, consumption and effects of cannabis, basic research on brain damage, genetic factors associated with substance use, and the physiological and neurological determinants of abstinence syndrome. The main works of reference that we identified were published in a small number of journals, which establish the intellectual, conceptual, and methodological basis of the discipline.

The US Air Force Office of Scientific Research convened a meeting of researchers in the fields of neuroscience, psychology, engineering, and medicine to discuss most pressing issues facing ongoing research in the field of transcranial direct current stimulation (tDCS) and related techniques. In this study, we present opinions prepared by participants of the meeting, focusing on the most promising areas of research, immediate and future goals for the field, and the potential for hormesis theory to inform tDCS research. Scientific, medical, and ethical considerations support the ongoing testing of tDCS in healthy and clinical populations, provided best protocols are used to maximize safety. Notwithstanding the need for ongoing research, promising applications include enhancing vigilance/attention in healthy volunteers, which can accelerate training and support learning. Commonly, tDCS is used as an adjunct to training/rehabilitation tasks with the goal of leftward shift in the learning/treatment effect curves. Although trials are encouraging, elucidating the basic mechanisms of tDCS will accelerate validation and adoption. To this end, biomarkers (eg, clinical neuroimaging and findings from animal models) can support hypotheses linking neurobiological mechanisms and behavioral effects. Dosage can be optimized using computational models of current flow and understanding dose–response. Both biomarkers and dosimetry should guide individualized interventions with the goal of reducing variability. Insights from other applied energy domains, including ionizing radiation, transcranial magnetic stimulation, and low-level laser (light) therapy, can be prudently leveraged. PMID:28210202

Asking the right questions in the right way: the need for a shift in research on psychological treatments for addiction.

PubMed

Orford, Jim

2008-06-01

To identify possible reasons for the disappointingly negative results of methodologically rigorous controlled trials of psychological treatments in the addictions field. A selective overview of the literature on addictive behaviour change. Eight failings of existing research are described: failing to account for the outcome equivalence paradox; neglecting relationships in favour of techniques; failing to integrate treatment research and research on unaided change; imposing an inappropriate time-scale on the change process; failing to take a systems or social network view; ignoring therapists' tacit theories; not including the patient's view; and displaying an ignorance of modern developments in the philosophy of science. Treatment research has been asking the wrong questions in the wrong way. Three necessary shifts in ways of conducting research are proposed: (i) the field should stop studying named techniques and focus instead on change processes; (ii) change processes should be studied within the broader, longer-acting systems of which treatment is part; and (iii) science in the field should be brought up to date by acknowledging a variety of sources of useful knowledge.

Investigation into the earliest signs of autism in infants has become a significant sub-field of autism research. This work invokes specific ethical concerns such as use of 'at-risk' language, communicating study findings to parents and the future perspective of enrolled infants when they reach adulthood. This study aimed to ground this research field in an understanding of the perspectives of members of the autism community. Following focus groups to identify topics, an online survey was distributed to autistic adults, parents of children with autism and practitioners in health and education settings across 11 European countries. Survey respondents (n = 2317) were positively disposed towards early autism research, and there was significant overlap in their priorities for the field and preferred language to describe infant research participants. However, there were also differences including overall less favourable endorsement of early autism research by autistic adults relative to other groups and a dislike of the phrase 'at-risk' to describe infant participants, in all groups except healthcare practitioners. The findings overall indicate that the autism community in Europe is supportive of early autism research. Researchers should endeavour to maintain this by continuing to take community perspectives into account. © The Author(s) 2016.

Setting research priorities by applying the combined approach matrix.

PubMed

Ghaffar, Abdul

2009-04-01

Priority setting in health research is a dynamic process. Different organizations and institutes have been working in the field of research priority setting for many years. In 1999 the Global Forum for Health Research presented a research priority setting tool called the Combined Approach Matrix or CAM. Since its development, the CAM has been successfully applied to set research priorities for diseases, conditions and programmes at global, regional and national levels. This paper briefly explains the CAM methodology and how it could be applied in different settings, giving examples and describing challenges encountered in the process of setting research priorities and providing recommendations for further work in this field. The construct and design of the CAM is explained along with different steps needed, including planning and organization of a priority-setting exercise and how it could be applied in different settings. The application of the CAM are described by using three examples. The first concerns setting research priorities for a global programme, the second describes application at the country level and the third setting research priorities for diseases. Effective application of the CAM in different and diverse environments proves its utility as a tool for setting research priorities. Potential challenges encountered in the process of research priority setting are discussed and some recommendations for further work in this field are provided.

Solving challenges in inter- and trans-disciplinary working teams: Lessons from the surgical technology field.

PubMed

Korb, Werner; Geißler, Norman; Strauß, Gero

2015-03-01

Engineering a medical technology is a complex process, therefore it is important to include experts from different scientific fields. This is particularly true for the development of surgical technology, where the relevant scientific fields are surgery (medicine) and engineering (electrical engineering, mechanical engineering, computer science, etc.). Furthermore, the scientific field of human factors is important to ensure that a surgical technology is indeed functional, process-oriented, effective, efficient as well as user- and patient-oriented. Working in such trans- and inter-disciplinary teams can be challenging due to different working cultures. The intention of this paper is to propose an innovative cooperative working culture for the interdisciplinary field of computer-assisted surgery (CAS) based on more than ten years of research on the one hand and the interdisciplinary literature on working cultures and various organizational theories on the other hand. In this paper, a retrospective analysis of more than ten years of research work in inter- and trans-disciplinary teams in the field of CAS will be performed. This analysis is based on the documented observations of the authors, the study reports, protocols, lab reports and published publications. To additionally evaluate the scientific experience in an interdisciplinary research team, a literature analysis regarding scientific literature on trans- and inter-disciplinarity was performed. Own research and literature analyses were compared. Both the literature and the scientific experience in an interdisciplinary research team show that consensus finding is not always easy. It is, however, important to start trans- and interdisciplinary projects with a shared mental model and common goals, which include communication and leadership issues within the project teams, i.e. clear and unambiguous information about the individual responsibilities and objectives to attain. This is made necessary due to differing leadership cultures within the cooperating disciplines. Another research outcome is the relevance of a cooperative learning culture throughout the complete duration of the project. Based on this cooperation, new ideas and projects were developed, i.e. a training concept for surgical trainers including technological competence for surgeons. An adapted innovative paradigm for a cooperating working culture in CAS is based on a shared mental model and common goals from the very beginning of a project. All actors in trans- and inter-disciplinary teams need to be interested in cooperation. This will lead to a common view on patients and technology models. Copyright © 2015 Elsevier B.V.

Role of Genomic Typing in Taxonomy, Evolutionary Genetics, and Microbial Epidemiology

van Belkum, Alex; Struelens, Marc; de Visser, Arjan; Verbrugh, Henri; Tibayrenc, Michel

2001-01-01

Currently, genetic typing of microorganisms is widely used in several major fields of microbiological research. Taxonomy, research aimed at elucidation of evolutionary dynamics or phylogenetic relationships, population genetics of microorganisms, and microbial epidemiology all rely on genetic typing data for discrimination between genotypes. Apart from being an essential component of these fundamental sciences, microbial typing clearly affects several areas of applied microbiogical research. The epidemiological investigation of outbreaks of infectious diseases and the measurement of genetic diversity in relation to relevant biological properties such as pathogenicity, drug resistance, and biodegradation capacities are obvious examples. The diversity among nucleic acid molecules provides the basic information for all fields described above. However, researchers in various disciplines tend to use different vocabularies, a wide variety of different experimental methods to monitor genetic variation, and sometimes widely differing modes of data processing and interpretation. The aim of the present review is to summarize the technological and fundamental concepts used in microbial taxonomy, evolutionary genetics, and epidemiology. Information on the nomenclature used in the different fields of research is provided, descriptions of the diverse genetic typing procedures are presented, and examples of both conceptual and technological research developments for Escherichia coli are included. Recommendations for unification of the different fields through standardization of laboratory techniques are made. PMID:11432813

Challenges, problems, and opportunities in consultation-liaison psychiatry research.

PubMed

Dimsdale, J E

1991-01-01

While consultation-liaison (C-L) psychiatry has blossomed as a psychiatric sub-specialty, C-L research remains relatively underdeveloped. Individual case reports or else small series studies predominate. In contrast, relatively few studies are hypothesis-driven, experimental, or include design features such as blinding or randomization. Now that the field has matured, it is ready for such studies. Aside from the fact that developing fields require time to develop a research infrastructure, another reason for the lag in consultation-liaison research is the distraction with other issues such as the continuing debate between advocates of consultation vs liaison, competition with behavioral medicine practitioners, and the quest for formal sub-specialization status. Unless the development of a firm research base is equally emphasized, one worries about the longterm intellectual development of this important area.

The measurement of intense E-fields is a fundamental need in various research areas. Integrated optical E-field sensors (IOESs) have important advantages and are potentially suitable for intense E-field detection. This paper comprehensively reviews the development and applications of several types of IOESs over the last 30 years, including the Mach-Zehnder interferometer (MZI), coupler interferometer (CI) and common path interferometer (CPI). The features of the different types of IOESs are compared, showing that the MZI has higher sensitivity, the CI has a controllable optical bias, and the CPI has better temperature stability. More specifically, the improvement work of applying IOESs to intense E-field measurement is illustrated. Finally, typical uses of IOESs in the measurement of intense E-fields are demonstrated, including application areas such as E-fields with different frequency ranges in high-voltage engineering, simulated nuclear electromagnetic pulse in high-power electromagnetic pulses, and ion-accelerating field in high-energy physics.

Recent National Institutes of Health changes have focused attention on the potential scientific impact of research projects. Research with the excellent potential to change subsequent science or health care practice may have high scientific impact. Only rigorous studies that address highly significant problems can generate change. Studies with high impact may stimulate new research approaches by changing understanding of a phenomenon, informing theory development, or creating new research methods that allow a field of science to move forward. Research with high impact can transition health care to more effective and efficient approaches. Studies with high impact may propel new policy developments. Research with high scientific impact typically has both immediate and sustained influence on the field of study. The article includes ideas to articulate potential scientific impact in grant applications as well as possible dissemination strategies to enlarge the impact of completed projects.

Discovering: Students' meanings for research

NASA Astrophysics Data System (ADS)

Rymer, John Ewan

The call for science education reforms in the mid-1980s resulted in the implementation of a new Alberta senior high school science curriculum in 1992. The reformed curriculum reflected the call for increased authentic practice in the sciences. Part of my interpretation of this curriculum included a month long field biology research project. The students' scientific understandings while involved in this project have been a source of wonder and curiosity for me. As teacher researcher, I sought to interpret the meanings students held for scientific research as they progressed through their self-directed investigations. In an urban high school two of my Biology 20 classes comprised of a total of fifty-four students were involved in this study. Using data collected from student questionnaire responses, student field notebooks and recorded conversations my interpretations were developed. Based on these interpretations it appeared that students' understandings of research altered slightly through the course of the field project. Initially, I interpreted students' meanings for scientific research to include the notion that an independent external world exists which may be methodologically studied. Research was both purposeful and personal, seeking to discover new knowledge through the use of advanced technologies. Over the course of the biology project the students' meanings came to include the sense that research involved dealing with the uncertainty of novelty. Research became dynamic in nature and was seen to be never ending. It became apparent from students' conversations with me that students were aware school social structures and responded to the research project through their understanding of these structures. The potential benefits desired in the reformers' call for authentic scientific practice may have been subverted to a degree by the students' acceptance of school social structures and their underlying discourse. As a result, the implementation of authentic science within the parameters of contemporary school discourse is questioned. I also realized my personal connection to the discourse and structures of schooling. As a result, my initial assumptions and practices in the biology project's implementation had to be reconsidered. This is one of the benefits of teacher research considered in my reflections.

Engaging students in research learning experiences through hydrology field excursions and short films

Ewen, Tracy; Seibert, Jan

2015-04-01

One of the best ways to engage students and instill enthusiasm for hydrology is to expose them to hands-on learning. A focus on hydrology field research can be used to develop context-rich and active learning, and help solidify idealized learning where students are introduced to individual processes through textbook examples, often neglecting process interactions and an appreciation for the complexity of the system. We introduced a field course where hydrological measurement techniques are used to study processes such as snow hydrology and runoff generation, while also introducing students to field research and design of their own field project. Additionally, we produced short films of each of these research-based field excursions, with in-house film expertise. These films present a short overview of field methods applied in alpine regions and will be used for our larger introductory hydrology courses, exposing students to field research at an early stage, and for outreach activities, including for potential high school students curious about hydrology. In the field course, students design a low-budget experiment with the aim of going through the different steps of a 'real' scientific project, from formulating the research question to presenting their results. During the field excursions, students make discharge measurements in several alpine streams with a salt tracer to better understand the spatial characteristics of an alpine catchment, where source waters originate and how they contribute to runoff generation. Soil moisture measurements taken by students in this field excursion were used to analyze spatial soil moisture patterns in the alpine catchment and subsequently used in a publication. Another field excursion repeats a published experiment, where preferential soil flow paths are studied using a tracer and compared to previously collected data. For each field excursion, observational data collected by the students is uploaded to an online database we developed, where students can also retrieve data from past excursions to further analyze and compare their data. At each of the field sites, weather stations were installed and a webviewer allows access to realtime data from data loggers, allowing students to explore how processes relate to climatic conditions. Together, these field excursions give students the necessary tools they will need to carry out field research of their own in future projects, whether in academia or industry, while the short films give potential or first-year students an impression of what hydrology is all about and hopefully inspire them to become future hydrologists.

Research infrastructures remain the key for state-of-the-art and successful research. In the last few decades, biobanks have become increasingly important in this field through standardization of biospecimen processing, sample storage, and standardized data management. Research infrastructure in cohort studies and other sample collection activities are currently experiencing a lack of long-term funding. In this article, the Biobank Graz discusses these aspects of sustainability including the definition of sustainability and necessity of a business plan, as well as cost calculation model in the field of biobanking. The economic state, critical success factors, and important operational issues are reviewed and described by the authors, using the example of the Biobank Graz. Sustainability in the field of biobanking is a globally important matter of necessity, starting from policy making and ending with security and documentation on each operational level.

Situational Awareness Applied to Geology Field Mapping using Integration of Semantic Data and Visualization Techniques

Houser, P. I. Q.

2017-12-01

21st century earth science is data-intensive, characterized by heterogeneous, sometimes voluminous collections representing phenomena at different scales collected for different purposes and managed in disparate ways. However, much of the earth's surface still requires boots-on-the-ground, in-person fieldwork in order to detect the subtle variations from which humans can infer complex structures and patterns. Nevertheless, field experiences can and should be enabled and enhanced by a variety of emerging technologies. The goal of the proposed research project is to pilot test emerging data integration, semantic and visualization technologies for evaluation of their potential usefulness in the field sciences, particularly in the context of field geology. The proposed project will investigate new techniques for data management and integration enabled by semantic web technologies, along with new techniques for augmented reality that can operate on such integrated data to enable in situ visualization in the field. The research objectives include: Develop new technical infrastructure that applies target technologies to field geology; Test, evaluate, and assess the technical infrastructure in a pilot field site; Evaluate the capabilities of the systems for supporting and augmenting field science; and Assess the generality of the system for implementation in new and different types of field sites. Our hypothesis is that these technologies will enable what we call "field science situational awareness" - a cognitive state formerly attained only through long experience in the field - that is highly desirable but difficult to achieve in time- and resource-limited settings. Expected outcomes include elucidation of how, and in what ways, these technologies are beneficial in the field; enumeration of the steps and requirements to implement these systems; and cost/benefit analyses that evaluate under what conditions the investments of time and resources are advisable to construct such system.

Each summer, UNAVCO hires students as part of the Plate Boundary Observatory (PBO) Student Field Assistant Program. PBO, the geodetic component of the NSF-funded EarthScope project, involves the reconnaissance, permitting, installation, documentation, and maintenance of 880 permanent GPS stations in five years. During the summer 2007, nine students from around the US and Puerto Rico were hired to assist PBO engineers during the busy summer field season. From June to September, students worked closely with PBO field engineers to install and maintain permanent GPS stations in all regions of PBO, including Alaska. The PBO Student Field Assistant Program provides students with professional hands-on field experience as well as continuing education in the geosciences. It also gives students a glimpse into the increasing technologies available to the science community, the scope of geophysical research utilizing these technologies, and the field techniques necessary to complete this research. Students in the PBO Field Assistant Program are involved in all aspects of GPS support, including in-warehouse preparation and in-field installations and maintenance. Students are taught practical skills such as drilling, wiring, welding, hardware configuration, documentation, and proper field safety procedures needed to construct permanent GPS stations. These real world experiences provide the students with technical and professional skills that are not always available to them in a classroom, and will benefit them greatly in their future studies and careers. The 2007 summer field season in Southern California consisted of over 35 GPS permanent station installations. To date, the Southern California region of PBO has installed over 190 GPS stations. This poster presentation will highlight the experiences gained by the Southern California student field assistants, while supporting PBO- Southern California GPS installations in the Mohave Desert and the Inyo National Forest.

Working and Learning in a Field Excursion.

PubMed

Hole, Torstein Nielsen

2018-06-01

This study aimed to discern sociocultural processes through which students learn in field excursions. To achieve this aim, short-term ethnographic techniques were employed to examine how undergraduate students work and enact knowledge (or knowing) during a specific field excursion in biology. The students participated in a working practice that employed research methods and came to engage with various biological phenomena over the course of their work. A three-level analysis of the students' experiences focused on three processes that emerged: participatory appropriation, guided participation, and apprenticeship. These processes derive from advances in practice-oriented theories of knowing. Through their work in the field, the students were able to enact science autonomously; they engaged with peers and teachers in specific ways and developed new understandings about research and epistemology founded on their experiences in the field. Further discussion about the use of "practice" and "work" as analytical concepts in science education is also included.

High school students' representations and understandings of electric fields

2016-12-01

This study investigates the representations and understandings of electric fields expressed by Chinese high school students 15 to 16 years old who have not received high school level physics instruction. The physics education research literature has reported students' conceptions of electric fields postinstruction as indicated by students' performance on textbook-style questions. It has, however, inadequately captured student ideas expressed in other situations yet informative to educational research. In this study, we explore students' ideas of electric fields preinstruction as shown by students' representations produced in open-ended activities. 92 participant students completed a worksheet that involved drawing comic strips about electric charges as characters of a cartoon series. Three students who had spontaneously produced arrow diagrams were interviewed individually after class. We identified nine ideas related to electric fields that these three students spontaneously leveraged in the comic strip activity. In this paper, we describe in detail each idea and its situated context. As most research in the literature has understood students as having relatively fixed conceptions and mostly identified divergences in those conceptions from canonical targets, this study shows students' reasoning to be more variable in particular moments, and that variability includes common sense resources that can be productive for learning about electric fields.

Fascination with In re Quinlan, the first high-profile right-to-die case in the United States, led the author to law school. By the time she received her law degree, bioethics was emerging as a field of study, and law and bioethics became her field. The mission of legal education is to teach students to "think like a lawyer," which can be a productive way to approach issues in many fields, including bioethics. Legal education can also teach individuals to respect people whose views on bioethics issues differ from their own. This essay describes three areas in which legal training influenced the author's work in bioethics: treatment decisions, research misconduct, and stem cell research.

FINESSE: Field Investigations to Enable Solar System Science and Exploration

The FINESSE (Field Investigations to Enable Solar System Science and Exploration) team is focused on a science and exploration field-based research program aimed at generating strategic knowledge in preparation for the human and robotic exploration of the Moon, near-Earth asteroids (NEAs) and Phobos and Deimos. We follow the philosophy that "science enables exploration and exploration enables science." 1) FINESSE Science: Understand the effects of volcanism and impacts as dominant planetary processes on the Moon, NEAs, and Phobos & Deimos. 2) FINESSE Exploration: Understand which exploration concepts of operations (ConOps) and capabilities enable and enhance scientific return. To accomplish these objectives, we are conducting an integrated research program focused on scientifically-driven field exploration at Craters of the Moon National Monument and Preserve in Idaho and at the West Clearwater Lake Impact Structure in northern Canada. Field deployments aimed at reconnaissance geology and data acquisition were conducted in 2014 at Craters of the Moon National Monument and Preserve. Targets for data acquisition included selected sites at Kings Bowl eruptive fissure, lava field and blowout crater, Inferno Chasm vent and outflow channel, North Crater lava flow and Highway lava flow. Field investigation included (1) differential GPS (dGPS) measurements of lava flows, channels (and ejecta block at Kings Bowl); (2) LiDAR imaging of lava flow margins, surfaces and other selected features; (3) digital photographic documentation; (4) sampling for geochemical and petrographic analysis; (5) UAV aerial imagery of Kings Bowl and Inferno Chasm features; and (6) geologic assessment of targets and potential new targets. Over the course of the 5-week field FINESSE campaign to the West Clearwater Impact Structure (WCIS) in 2014, the team focused on several WCIS research topics, including impactites, central uplift formation, the impact-generated hydrothermal system, multichronometer dating of impact products, and using WCIS as an analog test site for crew studies of sampling protocols. The FINESSE team visited and mapped all of the major islands within West Clearwater Lake. Excellent cliff exposures around the coasts of many of the islands allowed a general stratigraphy of impactites to be defined. Notable differences to previous work includes the discovery of a monomict lithic breccia and a medium to coarse grained impact melt rock. In addition, ample rock samples were returned from West Clearwater for geochronology study. Geochronology work centers around laboratory analyses of these samples (and samples collected in the future or obtained from archives housed at the Canadian Geological Survey). Samples returned from the FINESSE field season have been evaluated for suitability for geochronologic analysis, and selected samples have been crushed for mineral separation and/or sawed for the preparation of polished petrologic thin sections. Heavy minerals (e.g., zircon, titanite, and apatite) will be separated from the crushed material for (U-Th)/He geochronology. The sections will be used for laser ablation 40Ar/39Ar research after neutron irradiation. This presentation will highlight the exciting science and exploration work conducted by FINESSE, as well as future plans for continued research.

Workshop on Molecular Evolution

Cummings, Michael P.

Molecular evolution has become the nexus of many areas of biological research. It both brings together and enriches such areas as biochemistry, molecular biology, microbiology, population genetics, systematics, developmental biology, genomics, bioinformatics, in vitro evolution, and molecular ecology. The Workshop provides an important contribution to these fields in that it promotes interdisciplinary research and interaction, and thus provides a glue that sticks together disparate fields. Due to the wide range of fields addressed by the study of molecular evolution, it is difficult to offer a comprehensive course in a university setting. It is rare for a single institution to maintain expertise in all necessary areas. In contrast, the Workshop is uniquely able to provide necessary breadth and depth by utilizing a large number of faculty with appropriate expertise. Furthermore, the flexible nature of the Workshop allows for rapid adaptation to changes in the dynamic field of molecular evolution. For example, the 2003 Workshop included recently emergent research areas of molecular evolution of development and genomics.

Geoscience education is key for the understanding of our home, the planet Earth. The Lagos Ciência Viva Science Centre (CCVL) in Portugal develops various geoscience activities including astronomy sessions, geology, paleontology and oceanography field trips, complementary primary school classes, seminars and numerous workshops for a public ranging from pre-schoolers to seniors . Our experience in geoscience communication and informal education also includes a formal partnership with a research centre from the University of the Algarve, the CIMA - Centre for Marine and Environmental Research, through the project MOSES, which focuses on sand transport along crenulated coasts. Based on the project goals, methods and results, the CCVL team designed a communication and outreach plan including a seminar, a field trip and a workshop, to alert for the subjects of coastal erosion and management, both highly relevant in the Algarve. This partnership was highly beneficial for both parts as it facilitated the communication of a scientific project to the public, while the CCVL had the opportunity to update and expand its educational offer. This type of interaction between universities/research institutes and science centres/museums allows scientists to focus on their research work, reducing their need to invest in communication, and provides good and updated scientific contents to science communicators, ensuring a direct channel between scientific research and the public.

Research gaps for three main tropical diseases in the People’s Republic of China

PubMed Central

2013-01-01

This scoping review analyzes the research gaps of three diseases: schistosomiasis japonica, malaria and echinococcosis. Based on available data in the P.R. China, we highlight the gaps between control capacity and prevalence levels, and between diagnostic/drug development and population need for treatment at different stages of the national control programme. After reviewing the literature from 848 original studies and consultations with experts in the field, the gaps were identified as follows. Firstly, the malaria research gaps include (i) deficiency of active testing in the public community and no appropriate technique to evaluate elimination, (ii) lack of sensitive diagnostic tools for asymptomatic patients, (iii) lack of safe drugs for mass administration. Secondly, gaps in research of schistosomiasis include (i) incongruent policy in the implementation of integrated control strategy for schistosomiasis, (ii) lack of effective tools for Oncomelania sp. snail control, (iii) lack of a more sensitive and cheaper diagnostic test for large population samples, (iv) lack of new drugs in addition to praziquantel. Thirdly, gaps in research of echinococcosis include (i) low capacity in field epidemiology studies, (ii) lack of sanitation improvement studies in epidemic areas, (iii) lack of a sensitivity test for early diagnosis, (iv) lack of more effective drugs for short-term treatment. We believe these three diseases can eventually be eliminated in mainland China if all the research gaps are abridged in a short period of time. PMID:23895635

Baker, D. N.; Yamada, M.

Plasma physics provides a common language and set of approaches that tie together all scientists who study the acceleration, transport, and loss processes of the plasma state. Some years ago, researchers from the laboratory and space research communities suggested a workshop to bring together the diverse researchers in the respective fields. A series of workshops on the “Interrelationship between Plasma Experiments in the Laboratory and Space” (IPELS) was established, and the third meeting was held July 24-28, 1995, in the beautiful and historic town of Pitlochry in the Scottish Highlands.The conference reestablished the critical point that plasma physics is an important but surprisingly diversified research discipline. Meetings attendees discussed a number of new approaches to plasma research, including novel diagnostic techniques for use in space, such as active antennas and electric field sounding devices. Detailed discussions covered spacecraft-plasma environment interactions, including vehicle charging and neutral gas release; fundamental aspects of industrial application of dusty plasmas and waves in dusty plasmas; a very distinctive phase transition of coulomb crystals (from solid state to liquid state) in dusty plasmas; and terrella experiments to simulate and study chaotic transport in the ionosphere.

Recent findings related to childhood leukaemia incidence near nuclear installations have raised questions which can be answered neither by current knowledge on radiation risk nor by other established risk factors. In 2012, a workshop was organised on this topic with two objectives: (a) review of results and discussion of methodological limitations of studies near nuclear installations; (b) identification of directions for future research into the causes and pathogenesis of childhood leukaemia. The workshop gathered 42 participants from different disciplines, extending widely outside of the radiation protection field. Regarding the proximity of nuclear installations, the need for continuous surveillance of childhood leukaemia incidence was highlighted, including a better characterisation of the local population. The creation of collaborative working groups was recommended for consistency in methodologies and the possibility of combining data for future analyses. Regarding the causes of childhood leukaemia, major fields of research were discussed (environmental risk factors, genetics, infections, immunity, stem cells, experimental research). The need for multidisciplinary collaboration in developing research activities was underlined, including the prevalence of potential predisposition markers and investigating further the infectious aetiology hypothesis. Animal studies and genetic/epigenetic approaches appear of great interest. Routes for future research were pointed out.

Current safety practices in nano-research laboratories in China.

Zhang, Can; Zhang, Jing; Wang, Guoyu

2014-06-01

China has become a key player in the global nanotechnology field, however, no surveys have specifically examined safety practices in the Chinese nano-laboratories in depth. This study reports results of a survey of 300 professionals who work in research laboratories that handle nanomaterials in China. We recruited participants at three major nano-research laboratories (which carry out research in diverse fields such as chemistry, material science, and biology) and the nano-chemistry session of the national meeting of the Chinese Chemical Society. Results show that almost all nano-research laboratories surveyed had general safety regulations, whereas less than one third of respondents reported having nanospecific safety rules. General safety measures were in place in most surveyed nano-research laboratories, while nanospecific protective measures existed or were implemented less frequently. Several factors reported from the scientific literature including nanotoxicology knowledge gaps, technical limitations on estimating nano-exposure, and the lack of nano-occupational safety legislation may contribute to the current state of affairs. With these factors in mind and embracing the precautionary principle, we suggest strengthening or providing nanosafety training (including raising risk awareness) and establishing nanosafety guidelines in China, to better protect personnel in the nano-workplace.

The principles and operation plans of research-oriented teaching in the course of computer aided optical design are presented, especially the mode of research in practice course. This program includes contract definition phase, project organization and execution, post project evaluation and discussion. Modes of academic organization are used in the practice course of computer aided optical design. In this course the students complete their design projects in research teams by autonomous group approach and cooperative exploration. In this research process they experience the interpersonal relationship in modern society, the importance of cooperation in team, the functions of each individual, the relationships between team members, the competition and cooperation in one academic group and with other groups, and know themselves objectively. In the design practice the knowledge of many academic fields is applied including applied optics, computer programming, engineering software and etc. The characteristic of interdisciplinary is very useful for academic research and makes the students be ready for innovation by integrating the knowledge of interdisciplinary field. As shown by the practice that this teaching mode has taken very important part in bringing up the abilities of engineering, cooperation, digesting the knowledge at a high level and problem analyzing and solving.

Lamont-Doherty's Secondary School Field Research Program: Institutionalizing outreach to secondary school students at a soft-money research institute

NASA Astrophysics Data System (ADS)

Sambrotto, R.

2015-12-01

The Secondary School Field Research Program is a field and laboratory internship for high school students at the Lamont-Doherty Earth Observatory. Over the past 11 years it has grown into a significant program, engaging approximately 50 high school and college students each summer, most of them from ethnic and economic groups that are under-represented in the STEM fields. The internships are based on research-driven science questions on estuarine physics, chemistry, ecology and the paleo-environment. Field studies are linked to associated laboratory analyses whose results are reported by the students as a final project. For the past two years, we have focused on the transition to an institutional program, with sustainable funding and organizational structures. At a grant-driven institution whose mission is largely restricted to basic research, institutionalization has not been an easy task. To leverage scarce resources we have implemented a layered structure that relies on near-peer mentoring. So a typical research team might include a mix of new and more experienced high school students, a college student, a high school science teacher and a Lamont researcher as a mentor. Graduates of the program are employed to assist with administration. Knowledge and best practices diffuse through the organization in an organic, if not entirely structured, fashion. We have found that a key to long-term funding has been survival: as we have sustained a successful program and developed a model adapted to Lamont's unique environment, we have attracted longer term core financing on which grant-driven extensions can be built. The result is a highly flexible program that is student-centered in the context of a broader research culture connecting our participants with the advantages of working at a premier soft-money research institution.

PubMed

Farragher, Janine F; Elliott, Meghan J; Silver, Samuel A; Lichner, Zsuzsanna; Tsampalieros, Anne

2015-01-01

Translational research is an evolving discipline that is intended to bridge the gaps between basic science research, clinical research, and implementation in clinical practice. It is a fluid, multidirectional process that requires strong interdisciplinary collaboration to produce research that is relevant to end-users. This review summarizes current perspectives on translational research and outlines its relevance and importance to kidney transplantation research. Sources of information used for this review include published reports, articles, and research funding websites. Tissue typing is used as an in-depth example of how translational research has been applied in the field of kidney transplant medicine, and how it has resulted in successful implementation of diagnostic and management options for sensitized individuals undergoing kidney transplantation. The value of actively involving kidney transplant stakeholders (patients, caregivers, and clinicians) in setting research priorities and determining relevant outcomes for future investigation is also discussed. This is a narrative review of the literature which has been partly influenced by the perspectives and experiences of its authors. Translational and patient-oriented research practices should be incorporated into future research endeavours in the field of kidney transplantation in order to create beneficial change in clinical practice and improve patient outcomes. Translational research which engages patients in the investigative process can enhance the likelihood that medical discoveries will have a meaningful impact at the bedside. This article applies current perspectives on translational research and patient engagement to the field of kidney transplantation, illustrating how these approaches have led to significant advancements in the field. It provides further justification for deliberate, targeted efforts to cross-collaborate and incorporate the patient voice into kidney transplant research.

Chemical enhanced oil recovery (EOR) activities in Indonesia: How it's future

NASA Astrophysics Data System (ADS)

Abdurrahman, Muslim

2017-05-01

Enhanced oil recovery (EOR) is a proven method for increasing oil production in many oil fields in the world. Huge oil remaining in the reservoir after primary and secondary recovery stage are the main reason for developing EOR methods. Approximately of 49.50 billion barrels oil as a candidate for EOR activities in Indonesia. This present study focuses on the chemical EOR activities involved surfactant and polymer. This research based on pertinent information from various resources such as journal papers, conference papers, and report from the government. Based on this information, this paper explain in detail the progress of each project and it shows the potential oil field employ chemical EOR in the near future. Generally, the EOR activities can be categorized into two phases such as preliminary study phase and field implementation phase. In the preliminary study, the activities simply involve experimental and/or simulation works. Following the preliminary is the field implementation phase which can be categorized into three phases such as field trial, pilot project, and full-scale. In fact, several activities have been conducted by Lemigas (government oil and gas research center), Institut Teknologi Bandung, Institut Pertanian Bogor. These activities focused on laboratory and simulation work. Those institutions have been developing the chemical formula collaborating with oil companies for applying the EOR method in their oil fields. Currently, status of chemical EOR activities include 5 oil fields under pilot project and 12 oil fields under field trial. There are 7 oil fields applying surfactant, 4 oil fields by alkaline-surfactant-polymer (ASP), 2 oil fields by polymer, 1 oil field by surfactant polymer (SP), and 1 oil field by caustic. According to this information, we will have insight knowledge about the EOR current activities, the main issues, future activities on chemical EOR in Indonesia. Moreover, this study can became the preliminary information for researchers who interested conducting further research and development on the chemical EOR activities in the near future.

Computational Studies of Magnetic Nozzle Performance

NASA Technical Reports Server (NTRS)

Ebersohn, Frans H.; Longmier, Benjamin W.; Sheehan, John P.; Shebalin, John B.; Raja, Laxminarayan

2013-01-01

An extensive literature review of magnetic nozzle research has been performed, examining previous work, as well as a review of fundamental principles. This has allow us to catalog all basic physical mechanisms which we believe underlie the thrust generation process. Energy conversion mechanisms include the approximate conservation of the magnetic moment adiabatic invariant, generalized hall and thermoelectric acceleration, swirl acceleration, thermal energy transformation into directed kinetic energy, and Joule heating. Momentum transfer results from the interaction of the applied magnetic field with currents induced in the plasma plume., while plasma detachment mechanisms include resistive diffusion, recombination and charge exchange collisions, magnetic reconnection, loss of adiabaticity, inertial forces, current closure, and self-field detachment. We have performed a preliminary study of Hall effects on magnetic nozzle jets with weak guiding magnetic fields and weak expansions (p(sub jet) approx. = P(sub background)). The conclusion from this study is that the Hall effect creates an azimuthal rotation of the plasma jet and, more generally, creates helical structures in the induced current, velocity field, and magnetic fields. We have studied plasma jet expansion to near vacuum without a guiding magnetic field, and are presently including a guiding magnetic field using a resistive MHD solver. This research is progressing toward the implementation of a full generalized Ohm's law solver. In our paper, we will summarize the basic principle, as well as the literature survey and briefly review our previous results. Our most recent results at the time of submittal will also be included. Efforts are currently underway to construct an experiment at the University of Michigan Plasmadynamics and Electric Propulsion Laboratory (PEPL) to study magnetic nozzle physics for a RF-thruster. Our computational study will work directly with this experiment to validate the numerical model, in order to study magnetic nozzle physics and optimize magnetic nozzle design. Preliminary results from the PEPL experiment will also be presented.

Kim, Ock-Joo

Medical research during the Japanese Colonial Period became systematic and active after the Keijo Imperial University Medical School was established in 1926. Various kinds of research were conducted there including pharmacological, physiological, pathological and parasitological research. The Keijo Imperial University was give a mission to study about Korea. Urgent topics for medical research included control of infectious diseases, hygiene and environmental health that might have affected colonizing bodies of the Japanese as well as the colonized. The bodies of Koreans had been studied by Japanese even before the establishment of the University. The Keijo Imperial University research team, however, organized several field studies for physical anthropology and blood typing research at the national scale to get representative sampling of the people from its north to its south of the Korean peninsula. In the filed, they relied upon the local police and administrative power to gather reluctant women and men to measure them in a great detail. The physical anthropology and blood typing research by the Japanese researchers was related to their eagerness to place Korean people in the geography of the races in the world. Using racial index R.I.(= (A%+AB%)/(B%+AB%)), the Japanese researchers put Koreans as a race between the Mongolian and the Japanese. The preoccupation with constitution and race also pervasively affected the medical practice: race (Japanese, Korean, or Japanese living in Korea) must be written in every kind of medical chart as a default. After the breakout of Chinese-Japanese War in 1937, the Keijo Imperial University researchers extended its physical anthropology field study to Manchuria and China to get data on physics of the people in 1940. The Japanese government and research foundations financially well supported the Keijo Imperial University researchers and the field studies for physical anthropology in Korea, Manchuria and China. The physical anthropology research was actively conducted hand in hand with imperialistic expansion, and driven by zeal for measuring the body.

Research on Utilization of Geo-Energy

NASA Astrophysics Data System (ADS)

Bock, Michaela; Scheck-Wenderoth, Magdalena; GeoEn Working Group

2013-04-01

The world's energy demand will increase year by year and we have to search for alternative energy resources. New concepts concerning the energy production from geo-resources have to be provided and developed. The joint project GeoEn combines research on the four core themes geothermal energy, shale gas, CO2 capture and CO2 storage. Sustainable energy production from deep geothermal energy resources is addressed including all processes related to geothermal technologies, from reservoir exploitation to energy conversion in the power plant. The research on the unconventional natural gas resource, shale gas, is focussed on the sedimentological, diagenetic and compositional characteristics of gas shales. Technologies and solutions for the prevention of the greenhouse gas carbon dioxide are developed in the research fields CO2 capture technologies, utilization, transport, and CO2 storage. Those four core themes are studied with an integrated approach using the synergy of cross-cutting methodologies. New exploration and reservoir technologies and innovative monitoring methods, e.g. CSMT (controlled-source magnetotellurics) are examined and developed. All disciplines are complemented by numerical simulations of the relevant processes. A particular strength of the project is the availability of large experimental infrastructures where the respective technologies are tested and monitored. These include the power plant Schwarze Pumpe, where the Oxyfuel process is improved, the pilot storage site for CO2 in Ketzin and the geothermal research platform Groß Schönebeck, with two deep wells and an experimental plant overground for research on corrosion. In addition to fundamental research, the acceptance of new technologies, especially in the field of CCS is examined. Another focus addressed is the impact of shale gas production on the environment. A further important goal is the education of young scientists in the new field "geo-energy" to fight skills shortage in this field of growing economic and ecologic relevance.

Mapping Agricultural Fields in Sub-Saharan Africa with a Computer Vision Approach

NASA Astrophysics Data System (ADS)

Debats, S. R.; Luo, D.; Estes, L. D.; Fuchs, T.; Caylor, K. K.

2014-12-01

Sub-Saharan Africa is an important focus for food security research, because it is experiencing unprecedented population growth, agricultural activities are largely dominated by smallholder production, and the region is already home to 25% of the world's undernourished. One of the greatest challenges to monitoring and improving food security in this region is obtaining an accurate accounting of the spatial distribution of agriculture. Households are the primary units of agricultural production in smallholder communities and typically rely on small fields of less than 2 hectares. Field sizes are directly related to household crop productivity, management choices, and adoption of new technologies. As population and agriculture expand, it becomes increasingly important to understand both the distribution of field sizes as well as how agricultural communities are spatially embedded in the landscape. In addition, household surveys, a common tool for tracking agricultural productivity in Sub-Saharan Africa, would greatly benefit from spatially explicit accounting of fields. Current gridded land cover data sets do not provide information on individual agricultural fields or the distribution of field sizes. Therefore, we employ cutting edge approaches from the field of computer vision to map fields across Sub-Saharan Africa, including semantic segmentation, discriminative classifiers, and automatic feature selection. Our approach aims to not only improve the binary classification accuracy of cropland, but also to isolate distinct fields, thereby capturing crucial information on size and geometry. Our research focuses on the development of descriptive features across scales to increase the accuracy and geographic range of our computer vision algorithm. Relevant data sets include high-resolution remote sensing imagery and Landsat (30-m) multi-spectral imagery. Training data for field boundaries is derived from hand-digitized data sets as well as crowdsourcing.

Progress with High-Field Superconducting Magnets for High-Energy Colliders

Apollinari, Giorgio; Prestemon, Soren; Zlobin, Alexander V.

2015-10-01

One of the possible next steps for high-energy physics research relies on a high-energy hadron or muon collider. The energy of a circular collider is limited by the strength of bending dipoles, and its maximum luminosity is determined by the strength of final focus quadrupoles. For this reason, the high-energy physics and accelerator communities have shown much interest in higher-field and higher-gradient superconducting accelerator magnets. The maximum field of NbTi magnets used in all present high-energy machines, including the LHC, is limited to ˜10 T at 1.9 K. Fields above 10 T became possible with the use of Nb3Sn superconductors. Nb3Sn accelerator magnets can provide operating fields up to ˜15 T and can significantly increase the coil temperature margin. Accelerator magnets with operating fields above 15 T require high-temperature superconductors. This review discusses the status and main results of Nb3Sn accelerator magnet research and development and work toward 20-T magnets.

In biomedical fields, various materials are used for different purposes such as therapy, diagnostics and drugs. Some of them come into direct contact with blood and tissues in the human body, while many others are used in advanced medical equipment. Without these materials, current advances in medicine would never be achieved. Even in the 21st century, we still face the challenge of incurable or intractable diseases such as cancer, as well as the emergence of new infectious diseases. Global action is necessary to deal with these issues. Recent developments in nanoscience and nanotechnology have provided new strategies for material design that are based on the structural control of atoms and molecules. These strategies have revolutionized the field of advanced functional materials. Their combination with the enormous amount of knowledge in molecular and cellular biology accumulated over the last few decades has lead to the conception of new medical technologies. These technologies are represented in cell therapy, drug targeting and regenerative medicine, and are being widely and intensively investigated for realization at an industrial scale. In order to find solutions to remaining issues in life science, it is necessary to accelerate the fusion between nano- and biotechnologies and to promote research and development in these interdisciplinary fields. In this context, National Institute for Materials Science (NIMS)—one of the leading research institutes in the field of materials science—held a series of symposia in the week of 21-24 July 2009, 'NIMS Week 2009' and 'Nanobio-materials and technologies: breakthrough for future medicine', that aimed to present advances in medical fields from the perspective of materials science and technologies. During NIMS Week, various activities were carried out, including perspective reviews and invited lectures by international leading researchers in the 'nanobio' field, in addition to four organized sessions and related satellite symposia. Professor Kazunori Kataoka of the University of Tokyo received the NIMS Award 2009 for his outstanding research achievements and contributions to developing functional nanodevices for drug and gene delivery. This focus issue includes his review article 'Multifunctional nanoassemblies of block copolymers for future cancer therapy'. Eleven other plenary and invited speakers from NIMS Week 2009 have contributed review articles that may have great impact on research and development in nanobiomaterials and technologies Research in the nanobio field requires multi-disciplinary collaboration between specialists in biology, medicine, chemistry, physics, electronics, material engineering and other areas. We believe that this focus issue contains useful information for these researchers and provides an outline of breakthroughs for future medicine.

Field research opportunities for educators is leveraged as an invaluable tool to increase public engagement in climate research and the geosciences. We investigate the influence of educator's authentic fieldwork by highlighting the post-field impacts of a PolarTREC Teacher who participated in two campaigns, including NASA Operation IceBridge campaign over Antarctica in 2016. NASA's Operation IceBridge has hosted PolarTREC teachers since 2012, welcoming five teachers aboard multiple flights over the Arctic and one over Antarctica. The continuity of teacher inclusion in Operation IceBridge campaigns has facilitated a platform for collaborative curriculum development and revision, integration of National Snow and Ice Data Center (NSIDC) data into multiple classrooms, and given us a means whereby students can interact with science team members. I present impacts to my teaching and classrooms as I grapple with "Big Data" to allow students to work directly with lidar and radar data, I examine public outreach impacts through analytics from virtual networking tools including social media, NASA's Mission Tools Suite for Education, and field blog interactions.

PRELIMINARY DATA REPORT: HUMATE INJECTION AS AN ENHANCED ATTENUATION METHOD AT THE F-AREA SEEPAGE BASINS, SAVANNAH RIVER SITE

DOE Office of Scientific and Technical Information (OSTI.GOV)

Millings, M.

2013-09-16

A field test of a humate technology for uranium and I-129 remediation was conducted at the F-Area Field Research Site as part of the Attenuation-Based Remedies for the Subsurface Applied Field Research Initiative (ABRS AFRI) funded by the DOE Office of Soil and Groundwater Remediation. Previous studies have shown that humic acid sorbed to sediments strongly binds uranium at mildly acidic pH and potentially binds iodine-129 (I-129). Use of humate could be applicable for contaminant stabilization at a wide variety of DOE sites however pilot field-scale tests and optimization of this technology are required to move this technical approach frommore » basic science to actual field deployment and regulatory acceptance. The groundwater plume at the F-Area Field Research Site contains a large number of contaminants, the most important from a risk perspective being strontium-90 (Sr-90), uranium isotopes, I-129, tritium, and nitrate. Groundwater remains acidic, with pH as low as 3.2 near the basins and increasing to the background pH of approximately 5at the plume fringes. The field test was conducted in monitoring well FOB 16D, which historically has shown low pH and elevated concentrations of Sr-90, uranium, I-129 and tritium. The field test included three months of baseline monitoring followed by injection of a potassium humate solution and approximately four and half months of post monitoring. Samples were collected and analyzed for numerous constituents but the focus was on attenuation of uranium, Sr-90, and I-129. This report provides background information, methodology, and preliminary field results for a humate field test. Results from the field monitoring show that most of the excess humate (i.e., humate that did not sorb to the sediments) has flushed through the surrounding formation. Furthermore, the data indicate that the test was successful in loading a band of sediment surrounding the injection point to a point where pH could return to near normal during the study timeframe. Future work will involve a final report, which will include data trends, correlations and interpretations of laboratory data.« less

The Guidelines for the Use of Fishes in Research (2014; 2014 Guidelines), now available through the American fisheries Society (AFS) website and in print from the AFS bookstore, is a resource to aid researchers and regulatory authorities regarding responsible, scientifically valid research on fish and aquatic wildlife. The Guidelines for the Use of Fishes in Field Research (American Society of Ichthyologists and Herpetologists [ASIH] et al. 1987, 1988) emphasized field research and was followed by the 2004 Guidelines including laboratory research topics. Each version of the Guidelines has been jointly endorsed and/or published by the ASIH, the American Institute of Fishery Research Biologists (AIFRB), and AFS--each focusing on the scientific understanding, global conservation, and sustainability of aquatic animals, fisheries, and ecosystems. Changes with time necessitate revisions to make the Guidelines consistent with contemporary practices and scientific literature so to remain relevant as a technical resource. This document provides not only general principles relevant for field and laboratory research endeavors but includes specific requirements for researchers working within the United States and outside of the country. Within the scope of their expertise, the 2014 Uses of Fishers in Research (UFR) Committee members updated and revised sections, resulting in a 90-page 2014 Guidelines having undergone through peer review. As before, topical areas were addressed (see Table of Contents on page 416). Expanded coverage was provided on U.S. and international agencies and programs relevant to research with fishes. The Surgical Procedures and the Marking and Tagging section received special focus by a UFR Subcommittee. Feeds and Feeding and the Administration of Drugs, Biologics and Other Chemicals are just some of the newly added topics. The 2014 Guidelines is user-friendly by way of hyperlinks to external Internet sites, intradocument sections, and tables of acronyms with corresponding terms, low regulatory priority drugs, and Office of International des Epizooties notifiable disease agents. Again, the Institutional Animal Care and Use Committee (IACUC) role is explained, expectations for research are provided, and a brief checklist for IACUC readiness is included. Overall, the ,i>2014 Guidelines is the taxon-specific resource for our professional societies and is a principal document for standards on the care and use of fish and aquatic vertebrates in research.

2016-01-01

Graphene has attracted much attention of scientific community due to its enormous potential in different fields, including medical sciences, agriculture, food safety, cancer research, and tissue engineering. The potential for widespread human exposure raises safety concerns about graphene and its derivatives, referred to as graphene family nanomaterials (GFNs). Due to their unique chemical and physical properties, graphene and its derivatives have found important places in their respective application fields, yet they are being found to have cytotoxic and genotoxic effects too. Since the discovery of graphene, a number of researches are being conducted to find out the toxic potential of GFNs to different cell and animal models, finding their suitability for being used in new and varied innovative fields. This paper presents a systematic review of the research done on GFNs and gives an insight into the mode and action of these nanosized moieties. The paper also emphasizes on the recent and up-to-date developments in research on GFNs and their nanocomposites for their toxic effects. PMID:27051278

Biomimetics is a research field that is achieving particular prominence through an explosion of new discoveries in biology and engineering. The field concerns novel technologies developed through the transfer of function from biological systems. To analyze the impact of this field within engineering and related sciences, we compiled an extensive database of publications for study with network-based information analysis techniques. Criteria included publications by year and journal or conference, and subject areas judged by popular and common terms in titles. Our results reveal that this research area has expanded rapidly from less than 100 papers per year in the 1990s to several thousand papers per year in the first decade of this century. Moreover, this research is having impact across a variety of research themes, spanning robotics, computer science and bioengineering. In consequence, biomimetics is becoming a leading paradigm for the development of new technologies that will potentially lead to significant scientific, societal and economic impact in the near future.

He was a pioneer in the field of photosynthesis research; his contributions are many and wide-ranging. In the words of Jack Myers, he would be a "photosynthetiker" par excellence. He remained deeply engaged with research almost to the end of his life; we believe that generations of researchers still to come will benefit from his thorough and enormous work. We present here his life and some of his contributions to the field of Photosynthesis Research. The response to this tribute was overwhelming and we have included most of the tributes, which we received from all over the world. Prasanna Mohanty was a pioneer in the field of "Light Regulation of Photosynthesis", a loving and dedicated teacher-unpretentious, idealistic, and an honest human being.

Integrating Multiple Autonomous Underwater Vessels, Surface Vessels and Aircraft into Oceanographic Research Vessel Operations

NASA Astrophysics Data System (ADS)

McGillivary, P. A.; Borges de Sousa, J.; Martins, R.; Rajan, K.

2012-12-01

Autonomous platforms are increasingly used as components of Integrated Ocean Observing Systems and oceanographic research cruises. Systems deployed can include gliders or propeller-driven autonomous underwater vessels (AUVs), autonomous surface vessels (ASVs), and unmanned aircraft systems (UAS). Prior field campaigns have demonstrated successful communication, sensor data fusion and visualization for studies using gliders and AUVs. However, additional requirements exist for incorporating ASVs and UASs into ship operations. For these systems to be optimally integrated into research vessel data management and operational planning systems involves addressing three key issues: real-time field data availability, platform coordination, and data archiving for later analysis. A fleet of AUVs, ASVs and UAS deployed from a research vessel is best operated as a system integrated with the ship, provided communications among them can be sustained. For this purpose, Disruptive Tolerant Networking (DTN) software protocols for operation in communication-challenged environments help ensure reliable high-bandwidth communications. Additionally, system components need to have considerable onboard autonomy, namely adaptive sampling capabilities using their own onboard sensor data stream analysis. We discuss Oceanographic Decision Support System (ODSS) software currently used for situational awareness and planning onshore, and in the near future event detection and response will be coordinated among multiple vehicles. Results from recent field studies from oceanographic research vessels using AUVs, ASVs and UAS, including the Rapid Environmental Picture (REP-12) cruise, are presented describing methods and results for use of multi-vehicle communication and deliberative control networks, adaptive sampling with single and multiple platforms, issues relating to data management and archiving, and finally challenges that remain in addressing these technological issues. Significantly, the use of UAS on oceanographic research vessels is just beginning. We report on several initial field efforts which demonstrated that UAS improve spatial and temporal mapping of ocean features, as well as monitoring marine mammal populations, ocean color, sea ice and wave fields and air-sea gas exchange. These studies however also confirm the challenges for shipboard computer systems ingesting and archiving UAS high resolution video, SAR and lidar data. We describe the successful inclusion of DTN communications for: 1) passing video data between two UAS or a UAS and ship; 2) for inclusion of ASVs as communication nodes for AUVs; as well as, 3) enabling extension of adaptive sampling software from AUVs and ASVs to include UAS. In conclusion, we describe how autonomous sampling systems may be best integrated into shipboard oceanographic vessel research to provide new and more comprehensive time-space ocean and atmospheric data collection that is important not only for scientific study, but also for sustainable ocean management, including emergency response capabilities. The recent examples of such integrated studies highlighted confirm ocean and atmospheric studies can more cost-effectively pursued, and in some cases only accomplished, by combining underwater, surface and aircraft autonomous systems with research vessel operations.

Are you a researcher working in the polar regions of the world or a K-12 science teacher who would like to be part of a field research expedition in the polar regions? Researchers and K-12 science teachers can apply for funding from PolarTREC, a program that pairs researchers and teachers to conduct field science in Antarctica and the Arctic. Our poster presentation will offer details of one such successful researcher/teacher partnership. During the summer of 2016, Science Teacher Stan Skotnicki (Cheektowaga Central Middle School in Buffalo, NY) was teamed up with Assistant Professor Mike Loranty (Colgate University) to study vegetation and ecosystem impacts on permafrost vulnerability. Stan joined Mike and his research team in Northeastern Siberia preparing field sites, collecting data, processing samples, discussing methods, and planning daily activities. In order to raise awareness and broaden the impact of the research being conducted, Stan communicated the science through a series of journals on the PolarTREC website with his students, staff, and members of the community. Additionally, Mike and Stan held a live webinar from Siberia discussing the content of the research, the nature of the fieldwork, and why it was important to travel so far for this information. This expedition allowed Stan to experience working with a field research team for an extended period of time. Mike benefited from having a team member dedicated to learning about and communicating project details that also provided valuable field assistance. Stan gets to bring his hands-on experience back to his classroom in Buffalo and Mike has the opportunity to share his research with a new and different audience, including presenting to students at Cheektowaga Central with the help of his undergraduate students. This model of collaboration provides a number of valuable benefits for both teachers and researchers. While the PolarTREC program provides necessary logistics and funding to conduct these types of activities in polar regions, the approach is readily transferable to less remote locations, potentially at lower costs.

A research summary is presented that emphasizes ARS achievements in application technology over the past 2-3 years. Research focused on the improvement of agricultural pesticide application is important from the standpoint of crop protection as well as environmental safety. Application technology research is being actively pursued within the ARS, with a primary focus on application system development, drift management, efficacy enhancement and remote sensing. Research on application systems has included sensor-controlled hooded sprayers, new approaches to direct chemical injection, and aerial electrostatic sprayers. For aerial application, great improvements in on-board flow controllers permit accurate field application of chemicals. Aircraft parameters such as boom position and spray release height are being altered to determine their effect on drift. Other drift management research has focused on testing of low-drift nozzles, evaluation of pulsed spray technologies and evaluation of drift control adjuvants. Research on the use of air curtain sprayers in orchards, air-assist sprayers for row crops and vegetables, and air deflectors on aircraft has documented improvements in application efficacy. Research has shown that the fate of applied chemicals is influenced by soil properties, and this has implications for herbicide efficacy and dissipation in the environment. Remote sensing systems are being used to target areas in the field where pests are present so that spray can be directed to only those areas. Soil and crop conditions influence propensity for weeds and insects to proliferate in any given field area. Research has indicated distinct field patterns favorable for weed growth and insect concentration, which can provide further assistance for targeted spraying.

Because of its high biocompatibility, bio-degradability, low-cost and easy availability, cellulose finds application in disparate areas of research. Here we focus our attention on the most recent and attractive potential applications of cellulose in the biomedical field. We first describe the chemical/structural composition of cellulose fibers, the cellulose sources/features and cellulose chemical modifications employed to improve its properties. We then move to the description of cellulose potential applications in biomedicine. In this field, cellulose is most considered in recent research in the form of nano-sized particle, i.e., nanofiber cellulose (NFC) or cellulose nanocrystal (CNC). NFC is obtained from cellulose via chemical and mechanical methods. CNC can be obtained from macroscopic or microscopic forms of cellulose following strong acid hydrolysis. NFC and CNC are used for several reasons including the mechanical properties, the extended surface area and the low toxicity. Here we present some potential applications of nano-sized cellulose in the fields of wound healing, bone-cartilage regeneration, dental application and different human diseases including cancer. To witness the close proximity of nano-sized cellulose to the practical biomedical use, examples of recent clinical trials are also reported. Altogether, the described examples strongly support the enormous application potential of nano-sized cellulose in the biomedical field. PMID:28825682

Systematic and up-to-date Cochrane reviews in pediatrics in general and in pediatric gastroenterology in particular are important tools in disseminating the best available evidence to the medical community, thus providing the physician at the bedside with invaluable information and recommendations with regard to specific clinical questions. A systematic literature review was conducted, including all Cochrane reviews published by the Cochrane Review Group in the field of pediatric gastroenterology between 1993 and 2012, with regard to the percentage of reviews that concluded that a certain intervention provided a benefit, percentage of reviews that concluded that a certain intervention should not be performed, and percentage of studies that concluded that the current level of evidence was inconclusive. In total, 86 reviews in the field of pediatric gastroenterology were included. The majority of reviews assessed pharmacological interventions (46/86); other important fields included prevention (15/86) and nutrition (9/86). A total of 33/86 reviews issued definite recommendations (positive, 19/86; negative, 14/86). The remaining 53/86 reviews were either inconclusive (24/86) or only of limited conclusiveness (29/86). The percentage of inconclusive reviews increased from 9% (1998-2002) to 19% (2003-2007; P < 0.05) to finally 24% (2008-2012) (P < 0.05). The three most common reasons for the need for further research were heterogeneity of studies (26/86), small number of patients (18/86), and insufficient data (16/86). Further high-quality research is necessary to increase the proportion of reviews with clear recommendations. Funding and research agencies are key to selecting the most appropriate research programs. © 2014 Japan Pediatric Society.

Broadly defined, chemical information science (CIS) covers chemical structure and data analysis including biological activity data as well as processing, organization, and retrieval of any form of chemical information. The CIS Gateway (CISG) of F1000Research was created to communicate research involving the entire spectrum of chemical information, including chem(o)informatics. CISG provides a forum for high-quality publications and a meaningful alternative to conventional journals. This gateway is supported by leading experts in the field recognizing the need for open science and a flexible publication platform enabling off-the-beaten path contributions. This editorial aims to further rationalize the scope of CISG, position it within its scientific environment, and open it up to a wider audience. Chemical information science is an interdisciplinary field with high potential to interface with experimental work. PMID:29043072

Supporting Students with Disabilities Entering the Science, Technology, Engineering, and Mathematics Field Disciplines

Dishauzi, Karen M.

Extensive research exists on female, African American, and Hispanic students pursuing Science, Technology, Engineering and Mathematics (STEM) field disciplines. However, little research evaluates students with disabilities and career decision-making relating to STEM field disciplines. This study explored the career decision-making experiences and self-efficacy for students with disabilities. The purpose of this research study was to document experiences and perceptions of students with disabilities who pursue, and may consider pursuing, careers in the STEM field disciplines by exploring the career decision-making self-efficacy of students with disabilities. This study documented the level of influence that the students with disabilities had or may not have had encountered from parents, friends, advisors, counselors, and instructors as they managed their decision-making choice relating to their academic major/career in the STEM or non-STEM field disciplines. A total of 85 respondents of approximately 340 students with disabilities at one Midwestern public university completed a quantitatively designed survey instrument. The Career Decision-Making Self-Efficacy Scale-Short Form by Betz and Hackett was the instrument used, and additional questions were included in the survey. Data analysis included descriptive statistics and analysis of variance. Based upon the results, college students with disabilities are not currently being influenced by individuals and groups of individuals to pursue the STEM field disciplines. This is a cohort of individuals who can be marketed to increase enrollment in STEM programs at academic institutions. This research further found that gender differences at the institution under study did not affect the career decision-making self-efficacy scores. The men did not score any higher in confidence in career decision-making than the women. Disability type did not significantly affect the relationship between the Career Decision-Making Self-Efficacy Total Scores or college major choice. Of the three disability types represented more frequently, the Mental Health disability was found to be a growing disability at the institution under study. This research was found to be beneficial in the documentation of specific levels of influence perceived by students with disabilities from parents, friends, advisors, counselors, and instructors that related to their career decision-making and academic major choices.

Chapter 16: text mining for translational bioinformatics.

Text mining for translational bioinformatics is a new field with tremendous research potential. It is a subfield of biomedical natural language processing that concerns itself directly with the problem of relating basic biomedical research to clinical practice, and vice versa. Applications of text mining fall both into the category of T1 translational research-translating basic science results into new interventions-and T2 translational research, or translational research for public health. Potential use cases include better phenotyping of research subjects, and pharmacogenomic research. A variety of methods for evaluating text mining applications exist, including corpora, structured test suites, and post hoc judging. Two basic principles of linguistic structure are relevant for building text mining applications. One is that linguistic structure consists of multiple levels. The other is that every level of linguistic structure is characterized by ambiguity. There are two basic approaches to text mining: rule-based, also known as knowledge-based; and machine-learning-based, also known as statistical. Many systems are hybrids of the two approaches. Shared tasks have had a strong effect on the direction of the field. Like all translational bioinformatics software, text mining software for translational bioinformatics can be considered health-critical and should be subject to the strictest standards of quality assurance and software testing.

Research on the efficacy of yoga for improving mental, emotional, physical, and behavioral health characteristics in school settings is a recent but growing field of inquiry. This systematic review of research on school-based yoga interventions published in peer-reviewed journals offers a bibliometric analysis that identified 47 publications. The studies from these publications have been conducted primarily in the United States (n = 30) and India (n = 15) since 2005, with the majority of studies (n = 41) conducted from 2010 onward. About half of the publications were of studies at elementary schools; most (85%) were conducted within the school curriculum, and most (62%) also implemented a formal school-based yoga program. There was a high degree of variability in yoga intervention characteristics, including overall duration, and the number and duration of sessions. Most of these published research trials are preliminary in nature, with numerous study design limitations, including limited sample sizes (median = 74; range = 20-660) and relatively weak research designs (57% randomized controlled trials, 19% uncontrolled trials), as would be expected in an infant research field. Nevertheless, these publications suggest that yoga in the school setting is a viable and potentially efficacious strategy for improving child and adolescent health and therefore worthy of continued research. © 2016 New York Academy of Sciences.

Untold stories: biases and selection effects in research with victims of trafficking for sexual exploitation.

Recent discussions of trafficking research have included calls for more innovative studies and new methodologies in order to move beyond the current trafficking narrative, which is often based on unrepresentative samples and overly simplified images. While new methods can potentially play a role in expanding the knowledge base on trafficking, this article argues that the solution is not entirely about applying new methods, but as much about using current methods to greater effect and with careful attention to their limitations and ethical constraints. Drawing on the authors' experience in researching trafficking issues in a number of projects over the past decade, the article outlines and exemplifies some of the methodological and ethical issues to be considered and accommodated when conducting research with trafficked persons -- including unrepresentative samples; access to respondents; selection biases by "gatekeepers" and self selection by potential respondents. Such considerations should inform not only how research is undertaken but also how this information is read and understood. Moreover, many of these considerations equally apply when considering the application of new methods within this field. The article maintains that a better understanding of how these issues come into play and inform trafficking research will translate into tools for conducting improved research in this field and, by implication, new perspectives on human trafficking.

Infrasound is sound below the threshold of human hearing: approximately 20 Hz. The field of infrasound research, like other waveform based fields relies on several standard processing methods and data visualizations, including waveform plots and spectrograms. The installation of the International Monitoring System (IMS) global network of infrasound arrays, contributed to the resurgence of infrasound research. Array processing is an important method used in infrasound research, however, this method produces data sets with a large number of parameters, and requires innovative plotting techniques. The goal in designing new figures is to be able to present easily comprehendible, and information-rich plots by careful selection of data density and plotting methods.
