Earth and Space Sciences: The Need for Diversity in Global Science

NASA Astrophysics Data System (ADS)

Hall, F. R.; Johnson, R.; Alexander, C.

2004-12-01

The Earth and Space sciences are truly global in nature and encompass the most diverse subject areas in science. Yet, the practitioners of these fields do not reflect the diversity of the populations that are impacted by the outcomes of the research in these fields of study. The global marketplace, migration, the search for economic and renewable resources, Earth Systems research, and understanding our place in the universe compels us to be more inclusive of the populations and cultures that inhabit our planet. In this talk, we discuss the relevancy of these issues on scientific endeavors in the 21st century and the need for the Earth and Space sciences to be the leaders within the broad scientific community of ensuring that science remains an inclusive enterprise.

Review of Gender and Racial Diversity in Radiation Protection.

Gillenwalters, Elizabeth; Martinez, Nicole

The rapidly changing demographics of the United States workforce include a large number of women and members of minority groups that are currently underrepresented in science and engineering-related education and careers. Recent research indicates that while singular incidents of sexism do exist, gender bias more often affects women in various subtle ways. The effects of stereotype threat and the lack of appropriate mentoring and female role models are samples of the possible factors contributing to performance and longevity for women in math-intensive fields. To address how this issue affects those in radiation protection, the current status of women in the field is reviewed as a progression through the scientific pipeline, from education and employment to positions in scientific bodies and professional recognition, with primary focus on American women and institutions. Racial diversity demographics are reviewed where available. Findings indicate women and minority racial groups are underrepresented in multiple aspects of education, research, and leadership. While gender diversity across the field has not yet reached gender parity, trending indicates that the percentage of women earning degrees in radiation protection has consistently increased over the last four decades. Diversity of racial groups, however, has remained fairly consistent and is well below national averages. Diverse perspectives have been documented in collective problem-solving to lead to more innovative solutions.

Despite a century of research into the factors that generate and maintain biodiversity, we know remarkably little about the drivers of parasite diversity. To identify the mechanisms governing parasite diversity, we combined surveys of 8,100 amphibian hosts with an outdoor experiment that tested theory developed for free-living species. Our analyses revealed that parasite diversity increased consistently with host diversity due to habitat (i.e., host) heterogeneity, with secondary contributions from parasite colonization and host abundance. Results of the experiment, in which host diversity was manipulated while parasite colonization and host abundance were fixed, further reinforced this conclusion. Finally, the coefficient of host diversity on parasite diversity increased with spatial grain, which was driven by differences in their species-area curves: while host richness quickly saturated, parasite richness continued to increase with neighborhood size. These results offer mechanistic insights into drivers of parasite diversity and provide a hierarchical framework for multi-scale disease research. PMID:27147106

The majority of literature on mentoring focuses on mentee training needs, with significantly less guidance for the mentors. Moreover, many mentoring the mentor models assume generic (i.e. White) mentees with little attention to the concerns of underrepresented racial/ethnic minorities (UREM). This has led to calls for increased attention to diversity in research training programs, especially in the field of HIV where racial/ethnic disparities are striking. Diversity training tends to address the mentees' cultural competency in conducting research with diverse populations, and often neglects the training needs of mentors in working with diverse mentees. In this article, we critique the framing of diversity as the problem (rather than the lack of mentor consciousness and skills), highlight the need to extend mentor training beyond aspirations of cultural competency toward cultural humility and cultural safety, and consider challenges to effective mentoring of UREM, both for White and UREM mentors.

Crockett, Elahé T

2014-09-24

The National Institutes of Health has recognized a compelling need to train highly qualified individuals and promote diversity in the biomedical/clinical sciences research workforce. In response, we have developed a research-training program known as REPID (Research Education Program to Increase Diversity among Health Researchers) to prepare students/learners to pursue research careers in these fields and address the lack of diversity and health disparities. By inclusion of students/learners from minority and diverse backgrounds, the REPID program aims to provide a research training and enrichment experience through team mentoring to inspire students/learners to pursue research careers in biomedical and health-related fields. Students/learners are recruited from the University campus from a diverse population of undergraduates, graduates, health professionals, and lifelong learners. Our recruits first enroll into an innovative on-line introductory course in Basics and Methods in Biomedical Research that uses a laboratory Tool-Kit (a lab in a box called the My Dr. ET Lab Tool-Kit) to receive the standard basics of research education, e.g., research skills, and lab techniques. The students/learners will also learn about the responsible conduct of research, research concept/design, data recording/analysis, and scientific writing/presentation. The course is followed by a 12-week hands-on research experience during the summer. The students/learners also attend workshops and seminars/conferences. The students/learners receive scholarship to cover stipends, research related expenses, and to attend a scientific conference. The scholarship allows the students/learners to gain knowledge and seize opportunities in biomedical and health-related careers. This is an ongoing program, and during the first three years of the program, fifty-one (51) students/learners have been recruited. Thirty-six (36) have completed their research training, and eighty percent (80%) of them have continued their research experiences beyond the program. The combination of carefully providing standard basics of research education and mentorship has been successful and instrumental for training these students/learners and their success in finding biomedical/health-related jobs and/or pursuing graduate/medical studies. All experiences have been positive and highly promoted. This approach has the potential to train a highly qualified workforce, change lives, enhance biomedical research, and by extension, improve national health-care.

The EuroDIVERSITY Programme: Challenges of Biodiversity Science in Europe

NASA Astrophysics Data System (ADS)

Jonckheere, I.

2009-04-01

In close cooperation with its Member Organisations, the European Science Foundation (ESF) has launched since late 2003 a series of European Collaborative Research (EUROCORES) Programmes. Their aim is to enable researchers in different European countries to develop cooperation and scientific synergy in areas where European scale and scope are required in a global context. The EUROCORES instrument represents the first large scale attempt of national research (funding) agencies to act together against fragmentation, asynchronicity and duplication of research (funding) within Europe. Although covering all scientific fields, there are presently 13 EUROCORES Programmes dealing with cutting edge science in the fields of Earth, Climate and Environmental Sciences. The aim of the EuroDIVERSITY Programme is to support the emergence of an integrated biodiversity science based on an understanding of fundamental ecological and social processes that drive biodiversity changes and their impacts on ecosystem functioning and society. Ecological systems across the globe are being threatened or transformed at unprecedented rates from local to global scales due to the ever-increasing human domination of natural ecosystems. In particular, massive biodiversity changes are currently taking place, and this trend is expected to continue over the coming decades, driven by the increasing extension and globalisation of human affairs. The EuroDIVERSITY Programme meets the research need triggered by the increasing human footprint worldwide with a focus on generalisations across particular systems and on the generation and validation of theory relevant to experimental and empirical data. The EURODIVERSITY Programme tries to bridge the gaps between the natural and social sciences, between research work on terrestrial, freshwater and marine ecosystems, and between research work on plants, animals and micro-organisms. The Programme was launched in April 2006 and includes 10 international, multidisciplinary collaborative research projects, which are expected to contribute to this goal by initiating or strengthening major collaborative research efforts. Some projects are dealing primarily with microbial diversity (COMIX, METHECO, MiCROSYSTEMS), others try to investigate the biogeochemistry in grassland and forest ecosystems (BEGIN, BioCycle), the landscape and community ecology of biodiversity changes (ASSEMBLE, AGRIPOPES, EcoTRADE), and others focus on the diversity in freshwater (BIOPOOL, MOLARCH). In 2009, the EuroDIVERSITY Programme will integrate the different European research teams involved with collaborative field work campaigns over Europe, international workshops and conferences, as well as joint peer-review publications.

The Right Tools for the Job: The Challenges of Theory and Method in Geoscience Education Research

NASA Astrophysics Data System (ADS)

Riggs, E. M.

2011-12-01

As geoscience education has matured as a research field over the last decade, workers in this area have been challenged to adapt methodologies and theoretical approaches to study design and data collection. These techniques are as diverse as the earth sciences themselves, and researchers have drawn on established methods and traditions from science education research, social science research, and the cognitive and learning sciences. While the diversity of methodological and theoretical approaches is powerful, the challenge is to ground geoscience education research in rigorous methodologies that are appropriate for the epistemological and functional realities of the content area and the environment in which the research is conducted. The issue of theory is the first hurdle. After techniques are proven, earth scientists typically need not worry much about the theoretical value or theory-laden nature of measurements they make in the field or laboratory. As an example, a field geologist does not question the validity of the gravitational field that levels the spirit level within a Brunton compass. However, in earth science education research, these issues are magnified because a theoretical approach to a study affects what is admitted as data and the weight that can be given to conclusions. Not only must one be concerned about the validity of measurements and observations, but also the value of this information from an epistemological standpoint. The assigning of meaning to student gestures, utterances, writing and actions all carries theoretical implications. For example, working with geologists learning or working in the field, purely experimental research designs are very difficult, and the majority of the work must be conducted in a naturalistic environment. In fact dealing with time pressure, distractions, and complexity of a field environment is part of intellectual backdrop for field geology that separates experts from novices and advanced students from beginners. Thus researchers must embrace the uncontrolled nature of the setting, the qualitative nature of the data collected, and the researcher's role in interpreting geologically appropriate actions as evidence of successful problem solving and investigation. Working to understand the role of diversity and culture in the geosciences also involves a wide array of theory, from affective issues through culturally and linguistically-influenced cognition, through gender, self-efficacy, and many other areas of inquiry. Research in understanding spatial skills draws heavily on techniques from cognition research but also must involve the field-specific knowledge of geoscientists to infuse these techniques with exemplars, a catalog of meaningful actions by students, and an understanding of how to recognize success. These examples illustrate briefly the wide array of tools from other fields that is being brought to bear to advance rigorous geoscience education research. We will illustrate a few of these and the insights we have gained, and the power of theory and method from other fields to enlighten us as we attempt to educate a broader array of earth scientists.

Expanding the Scope of Site-Specific Recombinases for Genetic and Metabolic Engineering

Gaj, Thomas; Sirk, Shannon J.; Barbas, Carlos F.

2014-01-01

Site-specific recombinases are tremendously valuable tools for basic research and genetic engineering. By promoting high-fidelity DNA modifications, site-specific recombination systems have empowered researchers with unprecedented control over diverse biological functions, enabling countless insights into cellular structure and function. The rigid target specificities of many sites-specific recombinases, however, have limited their adoption in fields that require highly flexible recognition abilities. As a result, intense effort has been directed toward altering the properties of site-specific recombination systems by protein engineering. Here, we review key developments in the rational design and directed molecular evolution of site-specific recombinases, highlighting the numerous applications of these enzymes across diverse fields of study.

The discovery and characterization of protist communities from diverse environments are crucial for understanding the overall evolutionary history of life on earth. However, major questions about the diversity, ecology, and evolutionary history of protists remain unanswered, notably because data obtained from natural protist communities, especially of heterotrophic species, remain limited. In this review, we discuss the challenges associated with "field protistology", defined here as the exploration, characterization, and interpretation of microbial eukaryotic diversity within the context of natural environments or field experiments, and provide suggestions to help fill this important gap in knowledge. We also argue that increased efforts in field studies that combine molecular and microscopical methods offer the most promising path toward (1) the discovery of new lineages that expand the tree of eukaryotes; (2) the recognition of novel evolutionary patterns and processes; (3) the untangling of ecological interactions and functions, and their roles in larger ecosystem processes; and (4) the evaluation of protist adaptations to a changing climate. © 2013 The Author(s) Journal of Eukaryotic Microbiology © 2013 International Society of Protistologists.

ABSTRACT Despite increasing acknowledgment that microorganisms underpin the healthy functioning of basically all multicellular life, few cross-disciplinary teams address the diversity and function of microbiota across organisms and ecosystems. Our newly formed consortium of junior faculty spanning fields such as ecology and geoscience to mathematics and molecular biology from the University of Hawai‘i at Mānoa aims to fill this gap. We are united in our mutual interest in advancing a new paradigm for biology that incorporates our modern understanding of the importance of microorganisms. As our first concerted research effort, we will assess the diversity and function of microbes across an entire watershed on the island of Oahu, Hawai‘i. Due to its high ecological diversity across tractable areas of land and sea, Hawai‘i provides a model system for the study of complex microbial communities and the processes they mediate. Owing to our diverse expertise, we will leverage this study system to advance the field of biology. PMID:29556540

Society of Pediatric Psychology Diversity Award: Training Underrepresented Minority Students in Psychology

PubMed Central

Mitchell, Monica J.; Crosby, Lori E.

2016-01-01

Improving diversity, particularly among trainees and professionals from underrepresented ethnic minority backgrounds, has been a long-stated goal for the field of Psychology. Research has provided strategies and best practices, such as ensuring cultural sensitivity and relevance in coursework, clinical and research training, promoting a supportive and inclusive climate, providing access to cultural and community opportunities, and increasing insight and cultural competence among professionals (Rogers & Molina, 2006). Despite this, the rates of psychologists from ethnically diverse and underrepresented minority (URM) backgrounds remain low and few published studies have described programmatic efforts to increase diversity within the field. This paper describes the INNOVATIONS training model, which provides community and culturally related research experiences, graduate-school related advising, and mentoring to high school and college students. The paper also examines how the model may support enrollment of URM students in doctoral programs in psychology. Findings indicate that INNOVATIONS supported students’ transition from high school and college to graduate programs (with approximately 75% of students enrolling in Master’s and Doctoral programs). INNOVATIONS also supported students, including those from URM backgrounds, enrolling in doctoral programs (41.7%). Students who were trained in the research assistant track were most likely to enroll in psychology doctoral programs, perhaps as a result of the intensive time and training committed to research and clinical experiences. Data support the importance of research training for URM students pursuing psychology graduate study and the need to ensure cultural relevance of the training. Implications for clinical and pediatric psychology are discussed. PMID:28603680

Diversifying the Geosciences: Examples from the Arctic

NASA Astrophysics Data System (ADS)

Holmes, R. M.

2017-12-01

Like other realms of the geosciences, the scientists who comprise the Arctic research community tends to be white and male. For example, a survey of grants awarded over a 5-year period beginning in 2010 by NSF's Arctic System Science and Arctic Natural Sciences programs showed that over 90% of PIs were white whereas African Americans, Hispanics, and Native Americans together accounted for only about 1% of PIs. Over 70% of the PIs were male. I will suggest that involving diverse upper-level undergraduate students in authentic field research experiences may be one of the shortest and surest routes to diversifying the Arctic research community, and by extension, the geoscientific research community overall. Upper-level undergraduate students are still open to multiple possibilities, but an immersive field research experience often helps solidify graduate school and career trajectories. Though an all-of-the-above strategy is needed, focusing on engaging a diverse cohort of upper-level undergraduate students may provide one of the most efficient means of diversifying the geosciences over the coming years and decades.

Diversity, Geosciences, and Societal Impact: Perspectives From a Geoscientist, Workforce Development Specialist, and Former Congressional Science Fellow

NASA Astrophysics Data System (ADS)

Morris, A. R.

2014-12-01

In order for the United States to remain competitive in the STEM fields, all available interested citizens must be engaged, prepared, and retained in the geoscience workforce. The misperception that the geosciences do little to support the local community and give back to fellow citizens contributes to the lack of diversity in the field. Another challenge is that the assumptions of career paths for someone trained in geosciences are often limited to field work, perpetuated by visuals found in media, popular culture and recruiting materials and university websites. In order to combat these views it is critical that geoscientists make visible both the diverse career opportunities for those trained in geoscience and the relevance of the field to societal issues. In order to make a substantive change in the number of underrepresented minorities pursuing and working in geosciences we must rethink how we describe our work, its impacts and its relevance to society. At UNAVCO, we have undertaken this charge to change they way the future generation of geoscientists views opportunities in our field. This presentation will include reflections of a trained geoscientist taking a non-field/research career path and the opportunities it has afforded as well as the challenges encountered. The presentation will also highlight how experience managing a STEM program for middle school girls, serving as a Congressional Science Fellow, and managing an undergraduate research internship program is aiding in shaping the Geoscience Workforce Initiative at UNAVCO.

Discourses of dementia: a call for an ethnographic, action research approach to care in linguistically and culturally diverse environments.

The methods of ethnography and action research have much to offer to the field of speech-language pathology, particularly as our clinical populations are becoming increasingly diverse. We suggest that practicing speech-language pathologists and students, as well as researchers, will benefit from strategies that use the methods of participatory action research and ethnography as guiding principles to their work. Ethnography seeks to discover meaningful structures in a culture from the perspective of those whose culture it is. Action research, which shares a methodological basis with ethnography, is undertaken with the aim of improving the functioning of the social institution, practice, or structure investigated for the benefit of those most closely involved with that institution or practice. By way of illustration, we use data collected during fieldwork in Louisiana, involving persons with dementia from linguistically and culturally diverse backgrounds.

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

PubMed Central

2017-01-01

While behavioral and social sciences occupations comprise one of the largest portions of the “STEM” workforce, most studies of diversity in STEM overlook this population, focusing instead on fields such as biomedical or physical sciences. This study evaluates major demographic trends and productivity in the behavioral and social sciences research (BSSR) workforce in the United States during the past decade. Our analysis shows that the demographic trends for different BSSR fields vary. In terms of gender balance, there is no single trend across all BSSR fields; rather, the problems are field-specific, and disciplines such as economics and political science continue to have more men than women. We also show that all BSSR fields suffer from a lack of racial and ethnic diversity. The BSSR workforce is, in fact, less representative of racial and ethnic minorities than are biomedical sciences or engineering. Moreover, in many BSSR subfields, minorities are less likely to receive funding. We point to various funding distribution patterns across different demographic groups of BSSR scientists, and discuss several policy implications. PMID:28166252

The BSSR workforce is, in fact, less representative of racial and ethnic minorities than are biomedical sciences or engineering. Moreover, in many BSSR subfields, minorities are less likely to receive funding. We point to various funding distribution patterns across different demographic groups of BSSR scientists, and discuss several policy implications.

Does Interdisciplinary Research Lead to Higher Citation Impact? The Different Effect of Proximal and Distal Interdisciplinarity

PubMed Central

Yegros-Yegros, Alfredo; Rafols, Ismael; D’Este, Pablo

2015-01-01

This article analyses the effect of degree of interdisciplinarity on the citation impact of individual publications for four different scientific fields. We operationalise interdisciplinarity as disciplinary diversity in the references of a publication, and rather than treating interdisciplinarity as a monodimensional property, we investigate the separate effect of different aspects of diversity on citation impact: i.e. variety, balance and disparity. We use a Tobit regression model to examine the effect of these properties of interdisciplinarity on citation impact, controlling for a range of variables associated with the characteristics of publications. We find that variety has a positive effect on impact, whereas balance and disparity have a negative effect. Our results further qualify the separate effect of these three aspects of diversity by pointing out that all three dimensions of interdisciplinarity display a curvilinear (inverted U-shape) relationship with citation impact. These findings can be interpreted in two different ways. On the one hand, they are consistent with the view that, while combining multiple fields has a positive effect in knowledge creation, successful research is better achieved through research efforts that draw on a relatively proximal range of fields, as distal interdisciplinary research might be too risky and more likely to fail. On the other hand, these results may be interpreted as suggesting that scientific audiences are reluctant to cite heterodox papers that mix highly disparate bodies of knowledge—thus giving less credit to publications that are too groundbreaking or challenging.

Fire activity continues to increase in semi-arid regions around the globe. Private and governmental land management entities are challenged with predicting and mitigating post-fire hydrologic and erosion responses on these landscapes. For more than a decade, a team of scientists with the US Department of Agriculture has collaborated on extensive post-fire hydrologic field research and the application of field research to development of post-fire hydrology and erosion predictive technologies. Experiments funded through this research investigated the impacts of fire on vegetation and soils and the effects of these fire-induced changes on infiltration, runoff generation, erodibility, and soil erosion processes. The distribution of study sites spans diverse topography across grassland, shrubland, and woodland landscapes throughout the western United States. Knowledge gleaned from the extensive field experiments was applied to develop and enhance physically-based models for hillslope- to watershed-scale runoff and erosion prediction. Our field research and subsequent data syntheses have identified key knowledge gaps and challenges regarding post-fire hydrology and erosion modeling. Our presentation details some consistent trends across a diverse domain and varying landscape conditions based on our extensive field campaigns. We demonstrate how field data have advanced our understanding of post-fire hydrology and erosion for semi-arid landscapes and highlight remaining key knowledge gaps. Lastly, we briefly show how our well-replicated experimental methodologies have contributed to advancements in hydrologic and erosion model development for the post-fire environment.

Response of wild bees (Hymenoptera: Apoidea: Anthophila) to surrounding land cover in Wisconsin pickling cucumber.

PubMed

Lowenstein, D M; Huseth, A S; Groves, R L

2012-06-01

Cucumber (Cucumis sativus L.) is among the plants highly dependent on insect-mediated pollination, but little is known about its unmanaged pollinators. Both domestic and wild bee populations in central Wisconsin pickling cucumber fields were assessed using a combination of pan trapping and floral observations before and during bloom. Together with land cover analyses extending 2,000 m from field centers, the relationship of land cover components and bee abundance and diversity were examined. Over a 2-yr sample interval distributed among 18 experimental sites, 3,185 wild bees were collected representing >60 species. A positive association was found between both noncrop and herbaceous areas with bee abundance and diversity only during bloom. Response of bee abundance and diversity to land cover was strongest at larger buffers presumably because of the heterogeneous nature of the landscape and connectivity between crop and noncrop areas. These results are consistent with previous research that has found a weak response of wild bees to surrounding vegetation in moderately fragmented areas. A diverse community of wild bees is present within the fields of a commercial cucumber system, and there is evidence of floral visitation by unmanaged bees. This evidence emphasizes the importance of wild pollinators in fragmented landscapes and the need for additional research to investigate the effectiveness of individual species in pollen deposition.

Workflow technology is a generic mechanism to integrate diverse types of available resources (databases, servers, software applications and different services) which facilitate knowledge exchange within traditionally divergent fields such as molecular biology, clinical research, computational science, physics, chemistry and statistics. Researchers can easily incorporate and access diverse, distributed tools and data to develop their own research protocols for scientific analysis. Application of workflow technology has been reported in areas like drug discovery, genomics, large-scale gene expression analysis, proteomics, and system biology. In this article, we have discussed the existing workflow systems and the trends in applications of workflow based systems.

The Undergraduate Studies in Earthquake Information Technology (USEIT) is an REU Internship Program focused in multi-disciplinary, collaborative research offered through the Southern California Earthquake Center (SCEC); a research consortium focused on earthquake science. USEIT is an 8-week intensive undergraduate research program. The program is designed for interns to work as a collaborative engine to solve an overarching real-world earthquake problem referred to as the "Grand Challenge". The interns are organized in teams and paired with mentors that have expertise in their specific task in the Grand Challenge. The program is focused around earthquake system science, where students have the opportunity to use super computers, programming platforms, geographic information systems, and internally designed and developed visualization software. The goal of the USEIT program is to motivate undergraduates from diverse backgrounds towards careers in science and engineering through team-based research in the field of earthquake information technology. Efforts are made to recruit students with diverse backgrounds, taking into consideration gender, ethnic background, socioeconomic standing, major, college year, and institution type (2-year and 4-year colleges). USEIT has a partnership with two local community colleges to recruit underserved students. Our emphasis is to attract students that would 1) grow and develop technical skills, soft skills, and confidence from the program, and 2) provide perspective and innovation to the program. USEIT offers on-campus housing to provide a submerged learning environment, recruits diverse majors to foster interdisciplinary collaboration, maintains a full time in lab mentor for day-to-day intern needs, takes students on field trips to provide context to their research, and plans activities and field trips for team building and morale. Each year metrics are collected through exit surveys, personal statements, and intern experience statements. We highlight lessons learned, including a need for pre-program engagement to ensure student success.

Broadening Participation in the Geosciences through Participatory Research

NASA Astrophysics Data System (ADS)

Pandya, R. E.; Hodgson, A.; Wagner, R.; Bennett, B.

2009-12-01

In spite of many efforts, the geosciences remain less diverse than the overall population of the United States and even other sciences. This lack of diversity threatens the quality of the science, the long-term viability of our workforce, and the ability to leverage scientific insight in service of societal needs. Drawing on new research into diversity specific to geosciences, this talk will explore underlying causes for the lack of diversity in the atmospheric and related sciences. Causes include the few geoscience majors available at institutions with large minority enrollment; a historic association of the geosciences with extractive industries which are negatively perceived by many minority communities, and the perception that science offers less opportunity for service than other fields. This presentation suggests a new approach - community-based participatory research (CBPR). In CBPR, which was first applied in the field of rural development and has been used for many years in biomedical fields, scientists and community leaders work together to design a research agenda that simultaneously advances basic understanding and addresses community priorities. Good CBPR integrates research, education and capacity-building. A CBRP approach to geoscience can address the perceived lack of relevance and may start to ameliorate a history of negative experiences of geosciences. Since CBPR works best when it is community-initiated, it can provide an ideal place for Minority-Serving Institutions to launch their own locally-relevant programs in the geosciences. The presentation will conclude by describing three new examples of CBPR. The first is NCAR’s partnerships to explore climate change and its impact on Tribal lands. The second approach a Denver-area listening conference that will identify and articulate climate-change related priorities in the rapidly-growing Denver-area Latino community. Finally, we will describe a Google-funded project that brings together atmospheric scientists, epidemiologists, medical doctors, and economists to use improved precipitation forecasts to better manage Meningitis in Ghana.

This paper shows how the Rao-Stirling diversity index may be extensively used for positioning and comparing institutions interdisciplinary practices. Two decompositions of this index make it possible to explore different components of the diversity of the cited references in a corpus of publications. The paper aims at demonstrating how these bibliometric tools can be used for comparing institutions in a research field by highlighting collaboration orientations and institutions strategies. To make the method available and easy to use for indicator users, this paper first recalls a previous result on the decomposition of the Rao-Stirling index into multidisciplinarity and interdisciplinarity components, then proposes a new decomposition to further explore the profile of research collaborations and finally presents an application to Neuroscience research in French universities.

The use of multiple diverse measurements can make lensless phase retrieval more robust. Conventional diversity functions include aperture diversity, wavelength diversity, translational diversity, and defocus diversity. Here we discuss a lensless imaging scheme that employs multiple spherical-wave illuminations from a light-emitting diode array as diversity functions. In this scheme, we place a binary mask between the sample and the detector for imposing support constraints for the phase retrieval process. This support constraint enforces the light field to be zero at certain locations and is similar to the aperture constraint in Fourier ptychographic microscopy. We use a self-calibration algorithm to correct the misalignment of the binary mask. The efficacy of the proposed scheme is first demonstrated by simulations where we evaluate the reconstruction quality using mean square error and structural similarity index. The scheme is then experimentally tested by recovering images of a resolution target and biological samples. The proposed scheme may provide new insights for developing compact and large field-of-view lensless imaging platforms. The use of the binary mask can also be combined with other diversity functions for better constraining the phase retrieval solution space. We provide the open-source implementation code for the broad research community.

A general framework for analysing diversity in science, technology and society.

PubMed

Stirling, Andy

2007-08-22

This paper addresses the scope for more integrated general analysis of diversity in science, technology and society. It proposes a framework recognizing three necessary but individually insufficient properties of diversity. Based on 10 quality criteria, it suggests a general quantitative non-parametric diversity heuristic. This allows the systematic exploration of diversity under different perspectives, including divergent conceptions of relevant attributes and contrasting weightings on different diversity properties. It is shown how this heuristic may be used to explore different possible trade-offs between diversity and other aspects of interest, including portfolio interactions. The resulting approach offers a way to be more systematic and transparent in the treatment of scientific and technological diversity in a range of fields, including conservation management, research governance, energy policy and sustainable innovation.

"Biomedical Workforce Diversity: The Context for Mentoring to Develop Talents and Foster Success Within the 'Pipeline'".

PubMed

McGee, Richard

2016-09-01

Like all biomedical research fields, AIDS research needs the broadest diversity of experiences and perspectives among researchers in the field if creative advancements are to be achieved. Mentors and mentoring are the most important vehicles by which the talents of young scientists are developed. However, mentoring as a teaching and learning paradigm is very complex and idiosyncratic, and often inadvertently fails to provide the same quality and quantity of opportunity to aspiring scientists who are 'different' from those doing the mentoring. This article provides a theoretical and practical framework for understanding how differences of race, ethnicity, gender, skin color, social status and other identifiable characteristics can play into scientific development during mentoring 'within the pipeline'. It also serves as a foundation upon which mentoring in AIDS is considered by subsequent papers in this series. Finally, it goes beyond mentoring to propose systematic coaching as an effective complement to research mentoring to promote success, especially for individuals from underrepresented groups.

The nature and origin of human diversity has been a source of intellectual curiosity since the beginning of human history. Contemporary advances in cultural and biological sciences provide unique opportunities for the emerging field of cultural neuroscience. Research in cultural neuroscience examines how cultural and genetic diversity shape the human mind, brain and behavior across multiple time scales: situation, ontogeny and phylogeny. Recent progress in cultural neuroscience provides novel theoretical frameworks for understanding the complex interaction of environmental, cultural and genetic factors in the production of adaptive human behavior. Here, we provide a brief history of cultural neuroscience, theoretical and methodological advances, as well as empirical evidence of the promise of and progress in the field. Implications of this research for population health disparities and public policy are discussed. PMID:23914126

Comparative effectiveness research (CER) and community- based participatory research (CBPR) are two fields of research that do not have a history of strong collaboration. However, CER and CBPR researchers could benefit from interdisciplinary collaboration to design and implement relevant, timely, action-oriented research. This commentary explores field-specific definitions of stakeholders and then outlines various roles stakeholders might play within grant-funded research. Questions such as "What stakeholders should be involved?" and "How are stakeholders involved?" are addressed. The goal of this commentary is to highlight how the expertise and experiences of CBPR investigators can enhance the field of CER and to describe strategies for encouraging stakeholder involvement in CER research through the lens of CBPR. It is recommended that a team-based approach to conducting stakeholder-engaged CER encourages multiple stakeholders and "end users" to contribute their diverse expertise to the research process and contributes to the development of research with an increased likelihood of improving patient health and healthcare. © 2013 Wiley Periodicals, Inc.

Engaging large numbers of undergraduates in authentic scientific discovery is desirable but difficult to achieve. We have developed a general model in which faculty and teaching assistants from diverse academic institutions are trained to teach a research course for first-year undergraduate students focused on bacteriophage discovery and genomics. The course is situated within a broader scientific context aimed at understanding viral diversity, such that faculty and students are collaborators with established researchers in the field. The Howard Hughes Medical Institute (HHMI) Science Education Alliance Phage Hunters Advancing Genomics and Evolutionary Science (SEA-PHAGES) course has been widely implemented and has been taken by over 4,800 students at 73 institutions. We show here that this alliance-sourced model not only substantially advances the field of phage genomics but also stimulates students' interest in science, positively influences academic achievement, and enhances persistence in science, technology, engineering, and mathematics (STEM) disciplines. Broad application of this model by integrating other research areas with large numbers of early-career undergraduate students has the potential to be transformative in science education and research training. Engagement of undergraduate students in scientific research at early stages in their careers presents an opportunity to excite students about science, technology, engineering, and mathematics (STEM) disciplines and promote continued interests in these areas. Many excellent course-based undergraduate research experiences have been developed, but scaling these to a broader impact with larger numbers of students is challenging. The Howard Hughes Medical Institute (HHMI) Science Education Alliance Phage Hunting Advancing Genomics and Evolutionary Science (SEA-PHAGES) program takes advantage of the huge size and diversity of the bacteriophage population to engage students in discovery of new viruses, genome annotation, and comparative genomics, with strong impacts on bacteriophage research, increased persistence in STEM fields, and student self-identification with learning gains, motivation, attitude, and career aspirations.

During summers of 2007 and 2008 a series of International University Courses on Permafrost (IUCP) were conducted in West Siberia, Russia. Courses were organized as part of the International Permafrost Association (IPA) International Polar Year activities. The North of West Siberia region was selected to represent diverse permafrost, climatic and landscape conditions. The courses were jointly organized by the Moscow State University (MSU) and the Tumen' Oil and Gas University (TOGU) with the help from German and U.S. institutions. The program attracted undergraduate and graduate students with diverse interests and backgrounds from Germany, Russia and the U.S. and involved instructors specializing in different aspects of permafrost research. Courses were designed to address three major topics of permafrost-related research: a) permafrost environments characteristic of the discontinuous and continuous zones; b) field instrumentation and techniques; c) permafrost engineering and problems of development in permafrost regions. Methodologically, courses consisted of systematic permafrost investigations at long-term monitoring sites and survey-type expeditions. Systematic, process-based investigations were conducted at a network of sites which constitute the TEPO established by TOGU in collaboration with the gas company NadymGasProm. The observation complex includes an array of 30-m deep boreholes equipped with automatic data collection systems and representing characteristic permafrost landscapes of West Siberia. Boreholes are complemented by sites for snow cover, vegetation, soil, ground ice, and geomorphologic investigations. As part of student research activities, four new Circumpolar Active Layer Monitoring (CALM) sites were established in proximity to boreholes for monitoring spatial distribution and long-term dynamic of the active layer. New sites represent diverse landscapes characteristic of the West Siberian previously underrepresented in the CALM network. Specific emphasis was made on the study of permafrost soils. Throughout the course students were exposed to a wide range of field techniques, including surveying, coring, geothermal monitoring, thaw-depth measurements, landscape characterization, geomorphologic investigations, soil description and classification according to International, Russian, German, and U.S. classification schemes, and hydrologic and botanical field investigations. Significant portion of the course curriculum was devoted to problems of industrial development in permafrost regions. Pipelines, material sites, operating gas wells, processing plants, pump stations, and permafrost engineering testing facilities associated with three major gas fields (Yamburg, Yubileinoe, and Zapolyarnoe) were visited as part of the field excursions. Several meetings with Russian gas industry executives and workers were arranged to openly discuss economic and political issues associated with GasProm activities in West Siberia. The field work was complemented by daily lectures prepared by instructors and students, covering a wide range of topics. Students also participated in active permafrost research through daily data collection and analysis activities. Analysis of the diverse data sets obtained during the course was conducted at Moscow State University, presented in a series of detailed reports. The data collected by students were contributed to the international IPY permafrost monitoring programmes. Several students have presented results of their research at the Ninth International Conference on Permafrost and other national and international scientific meetings. This presentation describes research and educational activities of the IUCP, provides results of student research, and outlines the plan for the future.

There is a critical need for increasing the diversity representation among clinicians and researchers in academic medicine, including departments of psychiatry and psychology. Mentorship of under-represented groups has been identified as an important way to remediate diversity-related barriers in the field. This paper outlines the early development and pilot implementation of a diversity mentorship program at Brown University. In an effort to inform and guide future diversity programs, we discuss the challenges faced in creating the program, the successes experienced during the first year, and the future directions undertaken as a means for improving the program.

Chapel, Paul

1996-01-01

The U.S. Geological Survey (USGS) is known throughout the world for conducting quality scientific investigation is hydrologic environments. Proper and consistent field techniques have been an integral part of this good research. Over the past few decades, the USGS has developed and published detailed, standard protocols for conducting studies in most aspects of the hydrologic environment. These protocols have been published in a number of diverse documents. The wealth of information contained in these diverse documents can benefit other scientists in industry, government, and academia that are involved in conducting hydrologic studies. Scientists at the USGS have brought together many of the most important of the field protocols in a user-friendly, graphical-interfaced field manual that will be useful in both the field and in the office. This electronic field manual can assist hydrologists and other scientists in conducting and documenting their field activities in a manner that is recognized standard throughout the hydrologic community.

Microbial ecology provides insights into the ecological and evolutionary dynamics of microbial communities underpinning every ecosystem on Earth. Microbial communities can now be investigated in unprecedented detail, although there is still a wealth of open questions to be tackled. Here we identify 50 research questions of fundamental importance to the science or application of microbial ecology, with the intention of summarising the field and bringing focus to new research avenues. Questions are categorised into seven themes: host-microbiome interactions; health and infectious diseases; human health and food security; microbial ecology in a changing world; environmental processes; functional diversity; and evolutionary processes. Many questions recognise that microbes provide an extraordinary array of functional diversity that can be harnessed to solve real-world problems. Our limited knowledge of spatial and temporal variation in microbial diversity and function is also reflected, as is the need to integrate micro- and macro-ecological concepts, and knowledge derived from studies with humans and other diverse organisms. Although not exhaustive, the questions presented are intended to stimulate discussion and provide focus for researchers, funders and policy makers, informing the future research agenda in microbial ecology. © FEMS 2017.

Streletskiy, D. A.; Grebenets, V.; Ivanov, M.; Sheinkman, V.; Shiklomanov, N. I.; Shmelev, D.

2012-12-01

The international field school on permafrost was held in the Polar Urals region from June, 30 to July 9, 2012 right after the Tenth International Conference on Permafrost which was held in Salekhard, Russia. The travel and accommodation support generously provided by government of Yamal-Nenets Autonomous Region allowed participation of 150 permafrost young research scientists, out of which 35 students from seven countries participated in the field school. The field school was organized under umbrella of International Permafrost Association and Permafrost Young Research Network. The students represented diverse educational backgrounds including hydrologists, engineers, geologists, soil scientists, geocryologists, glaciologists and geomorphologists. The base school camp was located near the Harp settlement in the vicinity of Polar Urals foothills. This unique location presented an opportunity to study a diversity of cryogenic processes and permafrost conditions characteristic for mountain and plain regions as well as transition between glacial and periglacial environments. A series of excursions was organized according to the following topics: structural geology of the Polar Urals and West Siberian Plain (Chromite mine "Centralnaya" and Core Storage in Labitnangy city); quaternary geomorphology (investigation of moraine complexes and glacial conditions of Ronamantikov and Topographov glaciers); principles of construction and maintains of structures built on permafrost (Labitnangy city and Obskaya-Bovanenkovo Railroad); methods of temperature and active-layer monitoring in tundra and forest-tundra; cryosols and soil formation in diverse landscape condition; periglacial geomorphology; types of ground ice, etc. Every evening students and professors gave a series of presentations on climate, vegetation, hydrology, soil conditions, permafrost and cryogenic processes of the region as well as on history, economic development, endogenous population of the Siberia and the Russian Arctic in general. Series of discussions were focused on methodological aspects of permafrost research, data mining techniques, international projects, job opportunities etc. The experience gained by students during the field school, new networking opportunities and good spirit of polar research cannot be adequately replaced by any classroom demonstrations. That is why it is critically important to conduct such filed schools in the future. We are grateful to administration of Yamal-Nenets Autonomous region for providing financial support and to Yamal Tour for the organization and logistics in the field.

Advancing Diversity and Inclusion within the IceCube Collaboration: Lessons from an International Particle Astrophysics Research Collaboration

NASA Astrophysics Data System (ADS)

Knackert, J.

2017-12-01

The IceCube Collaboration is comprised of 300 scientists, engineers, students, and support staff at 48 institutions in 12 countries. IceCube recognizes the value of increased diversity within STEM fields and is committed to improving this situation both within the collaboration and more broadly. The process of establishing and maintaining a focus on diversity and inclusion within an international research collaboration has yielded many lessons and best practices relevant for broader STEM diversity efforts. Examples of events, training activities, and workshops to promote diversity both internally and within the broader STEM community will be provided. We will outline strategies to promote an environment of inclusivity and increase diversity in hiring within IceCube. We will describe collaborations with local networks and advocacy groups that have helped to guide our efforts and maximize their impact. We will also discuss methods for getting community members interested, informed, and invested, while helping them better understand the benefits associated with increased STEM diversity. This work has been informed by the American Association for the Advancement of Science's inaugural cohort of the Community Engagement Fellows Program. The author has made this submission on behalf of the IceCube Collaboration Diversity Task Force.

Behavioral Genetic Toolkits: Toward the Evolutionary Origins of Complex Phenotypes.

PubMed

Rittschof, C C; Robinson, G E

2016-01-01

The discovery of toolkit genes, which are highly conserved genes that consistently regulate the development of similar morphological phenotypes across diverse species, is one of the most well-known observations in the field of evolutionary developmental biology. Surprisingly, this phenomenon is also relevant for a wide array of behavioral phenotypes, despite the fact that these phenotypes are highly complex and regulated by many genes operating in diverse tissues. In this chapter, we review the use of the toolkit concept in the context of behavior, noting the challenges of comparing behaviors and genes across diverse species, but emphasizing the successes in identifying genetic toolkits for behavior; these successes are largely attributable to the creative research approaches fueled by advances in behavioral genomics. We have two general goals: (1) to acknowledge the groundbreaking progress in this field, which offers new approaches to the difficult but exciting challenge of understanding the evolutionary genetic basis of behaviors, some of the most complex phenotypes known, and (2) to provide a theoretical framework that encompasses the scope of behavioral genetic toolkit studies in order to clearly articulate the research questions relevant to the toolkit concept. We emphasize areas for growth and highlight the emerging approaches that are being used to drive the field forward. Behavioral genetic toolkit research has elevated the use of integrative and comparative approaches in the study of behavior, with potentially broad implications for evolutionary biologists and behavioral ecologists alike. © 2016 Elsevier Inc.

Diversity of Communications, Diversity of Communities: Strategic Choices for Maximum Engagement

NASA Astrophysics Data System (ADS)

Bartel, B. A.; Unger, M.

2017-12-01

One of the challenges around the edges of scientific research is finding ways to effectively communicate about that research beyond the confines of a highly specialized scientific community. While peer-review, publication, and scientific conferences and workshops allow scientists to effectively share their research with colleagues in their field, these exclusive communications do little to reach outside of those circles. Amid increasing requirements to demonstrate the value of research, and threats to funding of both basic and applied research, it becomes increasingly important for scientists and those in fields related to science communications to find, and continually update, tools for effectively reaching broad audiences. Drawing on experiences in science communications from various entities including the National Center for Atmospheric Research, UNAVCO, and the National Snow and Ice Data Center, we will present lessons learned that can be applied to communications endeavors on all scales, from individual researchers to large organizations. We will explore various channels, messengers, messages, and methods we have used effectively to reach diverse and broad audiences. In thinking about science communications, it is critical to not only understand the audiences we are attempting to reach, but also to meet them in the spaces they frequent. Therefore, we have found value in diversifying communications strategies in order to engage with diverse demographics, using the means most likely to connect with each. Multiple communications channels and strategies reach different age groups, speakers of different languages, and audiences of varying knowledge, experience, age, and interest levels. For example, on social media, Instagram reaches a young demographic and Pinterest is an ideal way to reach educators. Diversity in communications products and channels also addresses varying learning styles and moods, offering opportunities for explanations (e.g, videos), explorations (e.g., museum exhibits and online tools), and conversations (e.g., events). In addition to these topics, we will discuss how different channels can be used concurrently to support a communications campaign, the value of accessibility, choice of messaging, and the challenges in evaluating the success of each.

No correlation between the diversity and productivity of assemblages: evidence from the phytophage and predator assemblages in various cotton agroecosystems.

PubMed

Gao, Feng; Men, XingYuan; Ge, Feng

Biodiversity research has shown that primary productivity increases with plant species number, especially in many experimental grassland systems. Here, we assessed the correlation between productivity and diversity of phytophages and natural enemy assemblages associated with planting date and intercropping in four cotton agroecosystems. Twenty-one pairs of data were used to determine Pearson correlations between species richness, total number of individuals, diversity indices and productivity for each assemblage every five days from 5 June to 15 September 2012. At the same trophic level, the productivity exhibited a significant positive correlation with species richness of the phytophage or predator assemblage. A significant correlation was found between productivity and total number of individuals in most cotton fields. However, no significant correlations were observed between productivity and diversity indices (including indices of energy flow diversity and numerical diversity) in most cotton fields for either the phytophage or the predator assemblages. Species richness of phytophage assemblage and total individual numbers were significantly correlated with primary productivity. Also, species richness of natural enemy assemblage and total number of individuals correlated with phytophage assemblage productivity. A negative but not significant correlation occurred between the indices of numerical diversity and energy flow diversity and lower trophic-level productivity in the cotton-phytophage and phytophage-predator assemblages for most intercropped cotton agroecosystems. Our results clearly showed that there were no correlations between diversity indices and productivity within the same or lower trophic levels within the phytophage and predator assemblages in cotton agroecosystems, and inter-cropped cotton fields had a stronger ability to support the natural enemy assemblage and potentially to reduce phytophages.

The Physics of Complex Systems in Cuba

NASA Astrophysics Data System (ADS)

Sotolongo-Costa, Oscar

In relating the circumstances that led to the birth and development of the physics of complex systems in Cuba, it is difficult to avoid being anecdotal—particularly because of the difficult times during which this research started. Cuban eclecticism, whose spectrum extends from religious syncretism to world-class medicine, seems quite coherent with the field of complex systems, characterized by the synergy of diverse fields. Such a combination, however, in the beginning seemed to be quite removed from the physicists' standard research dogmas.

Contextual diversity facilitates learning new words in the classroom.

PubMed

Rosa, Eva; Tapia, José Luis; Perea, Manuel

2017-01-01

In the field of word recognition and reading, it is commonly assumed that frequently repeated words create more accessible memory traces than infrequently repeated words, thus capturing the word-frequency effect. Nevertheless, recent research has shown that a seemingly related factor, contextual diversity (defined as the number of different contexts [e.g., films] in which a word appears), is a better predictor than word-frequency in word recognition and sentence reading experiments. Recent research has shown that contextual diversity plays an important role when learning new words in a laboratory setting with adult readers. In the current experiment, we directly manipulated contextual diversity in a very ecological scenario: at school, when Grade 3 children were learning words in the classroom. The new words appeared in different contexts/topics (high-contextual diversity) or only in one of them (low-contextual diversity). Results showed that words encountered in different contexts were learned and remembered more effectively than those presented in redundant contexts. We discuss the practical (educational [e.g., curriculum design]) and theoretical (models of word recognition) implications of these findings.

The constraints of connecting children with nature--A research literature review

USGS Publications Warehouse

Ponds, Phadrea D.; Schuster, Rudy M.

2011-01-01

Reports or research investigations studying children in nature are rapidly expanding and increasingly diverse. This document reports a review of a particular part of this field-studies of constraints to recreation and participation in environmental and outdoor recreation programs. The findings result from a review of more than 125 journal articles, books, and reports that were published between 1980 and 2009. This report discusses how the current information concerning constraints to participation can be understood in terms of four concentrations or foci of work generated in this particular field of study. These foci, which are all well established in the literature, are (1) intrapersonal, interpersonal, and structural constraints, (2) significant life experiences, (3) environmental attitudes, values and beliefs, and (4) environmental behaviors. The recent research associated with each of these research areas is discussed in successive sections of the review. Overall, this review found that the research on constraints that inhibit children's connection to nature is less diverse in terms of methodological and theoretical approaches than is the research into the broader outdoor recreation research field within which it is situated. This review focused on the issue of connecting children with nature, but examples from studies using adults to understand childhood experiences and recreation preferences were used because there are relatively few peer-reviewed articles showing the theoretical or empirical connection of children and nature. In some cases, broader empirical studies were used to connect with larger themes (that is, environmental attitudes, beliefs, and values).

Lampreys as Diverse Model Organisms in the Genomics Era.

Lampreys, one of the two surviving groups of ancient vertebrates, have become important models for study in diverse fields of biology. Lampreys (of which there are approximately 40 species) are being studied, for example, (a) to control pest sea lamprey in the North American Great Lakes and to restore declining populations of native species elsewhere; (b) in biomedical research, focusing particularly on the regenerative capability of lampreys; and (c) by developmental biologists studying the evolution of key vertebrate characters. Although a lack of genetic resources has hindered research on the mechanisms regulating many aspects of lamprey life history and development, formerly intractable questions are now amenable to investigation following the recent publication of the sea lamprey genome. Here, we provide an overview of the ways in which genomic tools are currently being deployed to tackle diverse research questions and suggest several areas that may benefit from the availability of the sea lamprey genome.

Leveraging Community to Promote Diversity and Inclusion within the IceCube Collaboration

NASA Astrophysics Data System (ADS)

Knackert, J.

2017-12-01

The IceCube Collaboration is an international research collaboration working to advance the field of particle astrophysics. It is comprised of more than 300 scientists, engineers, students, and support staff at 48 institutions in 12 countries. IceCube recognizes the value of increased diversity within STEM fields and is committed to improving this situation both within the collaboration and more broadly. The collaboration has dedicated a community manager to help coordinate and promote these efforts and has established a diversity task force as an internal resource and advising body. Here we will discuss how existing community structure was utilized to establish and maintain a focus on diversity within the collaboration. We will discuss methods for getting community members interested, informed, and invested, while helping them better understand the benefits associated with increased STEM diversity. We will also highlight the advantages of building a team of advocates within a community and the impact these individuals can have both internally and beyond. This work has been informed by the American Association for the Advancement of Science's inaugural cohort of the Community Engagement Fellows Program. The author has made the submission on behalf of the IceCube Collaboration Diversity Task Force.

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

NASA Astrophysics Data System (ADS)

Myles, L.

2017-12-01

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.

Advancing biodiversity-ecosystem functioning science using high-density tree-based experiments over functional diversity gradients.

PubMed

Tobner, Cornelia M; Paquette, Alain; Reich, Peter B; Gravel, Dominique; Messier, Christian

2014-03-01

Increasing concern about loss of biodiversity and its effects on ecosystem functioning has triggered a series of manipulative experiments worldwide, which have demonstrated a general trend for ecosystem functioning to increase with diversity. General mechanisms proposed to explain diversity effects include complementary resource use and invoke a key role for species' functional traits. The actual mechanisms by which complementary resource use occurs remain, however, poorly understood, as well as whether they apply to tree-dominated ecosystems. Here we present an experimental approach offering multiple innovative aspects to the field of biodiversity-ecosystem functioning (BEF) research. The International Diversity Experiment Network with Trees (IDENT) allows research to be conducted at several hierarchical levels within individuals, neighborhoods, and communities. The network investigates questions related to intraspecific trait variation, complementarity, and environmental stress. The goal of IDENT is to identify some of the mechanisms through which individuals and species interact to promote coexistence and the complementary use of resources. IDENT includes several implemented and planned sites in North America and Europe, and uses a replicated design of high-density tree plots of fixed species-richness levels varying in functional diversity (FD). The design reduces the space and time needed for trees to interact allowing a thorough set of mixtures varying over different diversity gradients (specific, functional, phylogenetic) and environmental conditions (e.g., water stress) to be tested in the field. The intention of this paper is to share the experience in designing FD-focused BEF experiments with trees, to favor collaborations and expand the network to different conditions.

This article applies scientometric techniques to study the evolution of the field of entrepreneurship between 1990 and 2013. Using a combination of topic mapping, author and journal co-citation analyses, and overlay visualization of new and hot topics in the field, this article makes important contribution to the entrepreneurship research by identifying 46 topics in the 24-year history of entrepreneurship research and demonstrates how they appear, disappear, reappear and stabilize over time. It also identifies five topics that are persistent across the 24-year study period--institutions and institutional entrepreneurship, innovation and technology management, policy and development, entrepreneurial process and opportunity, and new ventures--which I labeled as The Pentagon of Entrepreneurship. Overall, the analyses revealed patterns of convergence and divergence and the diversity of topics, specialization, and interdisciplinary engagement in entrepreneurship research, thus offering the latest insights on the state of the art of the field.

Meeting the Challenges for Gender Diversity in the Geosciences

Women are now routinely chief scientists on major cruises, lead field parties to all continents, and have risen to leadership positions in professional organizations, academic departments and government agencies including major funding agencies. They teach at all levels, advise research students, make research discoveries and receive honors in recognition of their achievements. Despite these advances, women continue to be under-represented in the earth, ocean, and atmospheric sciences. As of 1997 women received only 29% of the doctorates in the earth, atmospheric, and oceanographic sciences and accounted for only 13% of employed Ph.D.s in these fields. Women's salaries also lag: the median annual salary for all Ph.D. geoscientists was \\60,000; for women the figure is \\47,000. Solving the problem of gender imbalance in the geosciences requires understanding of the particular obstacles women face in our field. The problem of under-representation of women requires that earth science departments, universities and research centers, funding agencies, and professional organizations like AGU take constructive action to recognize the root causes of the evident imbalance, and enact corrective policies. We have identified opportunities and challenges for each of these groups. A systematic study of the flux of women at Columbia University enabled a targeted strategy towards improving gender diversity based on the observed trends. The challenge for academic institutions is to document the flux of scientists and develop an appropriate strategy to balance the geoscience demographics. Based on the MIT study, an additional challenge faces universities and research centers. To enhance gender diversity these institutions need to develop transparency in promotion processes and open distribution of institutional resources. The challenge for granting agencies is to implement policies that ease the burden of extensive fieldwork on parents. Many fields of science require long work hours but the geosciences are unique in their requirement of extended fieldwork in remote locations, which raises issues for parents, and may be one reason geosciences lags behind other science disciplines in gender diversity. AGU and AGI have both conducted comprehensive and important studies on the status of women in science at all levels. Conducting flux studies and identifying the decision points in the advancement of scientists will provide fundamental data for designing successful programs to enhance diversity in the geosciences. Professional organizations such as AGU and the Geological Society of America should develop projects to monitor the career patterns of scientists, both men and women, beyond graduate school and the first job.

Methodology discourses as boundary work in the construction of engineering education.

PubMed

Beddoes, Kacey

2014-04-01

Engineering education research is a new field that emerged in the social sciences over the past 10 years. This analysis of engineering education research demonstrates that methodology discourses have played a central role in the construction and development of the field of engineering education, and that they have done so primarily through boundary work. This article thus contributes to science and technology studies literature by examining the role of methodology discourses in an emerging social science field. I begin with an overview of engineering education research before situating the case within relevant bodies of literature on methodology discourses and boundary work. I then identify two methodology discourses--rigor and methodological diversity--and discuss how they contribute to the construction and development of engineering education research. The article concludes with a discussion of how the findings relate to prior research on methodology discourses and boundary work and implications for future research.

Research documents a lack of access to, utilization of, and satisfaction with hospice care for African Americans. Models for culturally competent hospice services have been developed but are not in general use. Major organizational barriers include (1) lack of funding/budgeting for additional staff for community outreach, (2) lack of applications from culturally diverse professionals, (3) lack of funding/budgeting for additional staff for development of culturally competent services, (4) lack of knowledge about diverse cultures, and (5) lack of awareness of which cultural groups are not being served. A participatory action research project addressed these organizational barriers through a multicultural social work student field placement in 1 rural hospice. The effectiveness of the student interventions was evaluated, including addressing organizational barriers, cultural competence training of staff, and community outreach. Results indicated that students can provide a valuable service in addressing organizational barriers through a hospice field placement.

Bridging the Dialectic: Diversity, Psychological Sense of Community, and Inclusion.

PubMed

Brodsky, Anne E

2017-06-01

Although, there are many times when P/SOC and diversity appear in opposition, I argue that this conflict is not inherent to the concepts or their joint value, but to social contexts in which they are enacted in real life. The primary values of community psychology-building and supporting positive communities, social change, and social justice within a framework that recognizes the centrality of diversity, culture, inclusion, power, and privilege-actually bind diversity and community together. Thus, we can bridge this seeming dialectic through deeper reflection about the real and intended meaning, operationalization, and application of these two terms, and a reliance on the central values of our field. © Society for Community Research and Action 2017.

Determination of a Screening Metric for High Diversity DNA Libraries.

Guido, Nicholas J; Handerson, Steven; Joseph, Elaine M; Leake, Devin; Kung, Li A

2016-01-01

The fields of antibody engineering, enzyme optimization and pathway construction rely increasingly on screening complex variant DNA libraries. These highly diverse libraries allow researchers to sample a maximized sequence space; and therefore, more rapidly identify proteins with significantly improved activity. The current state of the art in synthetic biology allows for libraries with billions of variants, pushing the limits of researchers' ability to qualify libraries for screening by measuring the traditional quality metrics of fidelity and diversity of variants. Instead, when screening variant libraries, researchers typically use a generic, and often insufficient, oversampling rate based on a common rule-of-thumb. We have developed methods to calculate a library-specific oversampling metric, based on fidelity, diversity, and representation of variants, which informs researchers, prior to screening the library, of the amount of oversampling required to ensure that the desired fraction of variant molecules will be sampled. To derive this oversampling metric, we developed a novel alignment tool to efficiently measure frequency counts of individual nucleotide variant positions using next-generation sequencing data. Next, we apply a method based on the "coupon collector" probability theory to construct a curve of upper bound estimates of the sampling size required for any desired variant coverage. The calculated oversampling metric will guide researchers to maximize their efficiency in using highly variant libraries.

Abstract A growing body of evidence highlights the importance of competent mentoring in academic research in the field of HIV, particularly for early stage investigators from diverse, underrepresented backgrounds. We describe the development and implementation of a 2-day intensive workshop to train mid-level and senior-level investigators conducting HIV-related clinical and translational research across multiple academic institutions on more effective mentoring, with an emphasis on techniques to foster mentees of diversity. The workshop was focused on training mentors in techniques designed to improve the effectiveness of the mentor-mentee relationship, and included didactic presentations, interactive discussions, and small-group problem-based learning activities. Mid-level or senior-level faculty involved or planning to be involved in significant mentorship activities related to HIV research were eligible. Surveys and formal actions plans allowed for workshop evaluation and laid the groundwork for subsequent workshops. Twenty-six faculty from 16 U.S.-based institutions participated, with good representation across discipline, gender, and race/ethnicity. The sessions were highly rated and discussions and evaluations revealed important barriers and facilitators to mentoring, challenges and solutions related to mentoring mentees from diverse backgrounds, and specific tools to enhance mentoring effectiveness. The Mentoring the Mentors training program for HIV researchers focusing on early career investigators of diversity was the first of its kind and was well attended, was rated highly, and provided guidance for improving the program in the future. This training program fills an important gap in the HIV researcher community and offers guidance for training mentors interested in diversity issues in settings outside of HIV.

Field trip method through investigation of local biodiversity cases can give educational experiences for students. This learning activity was efforts to reveal students environmental literacy on biodiversity. The aim of study were (1) to describe the activities of students get information about the biodiversity issue and its context through field trip, (2) to describe the students findings during field trip, and (3) to reveal students environmental literacy based on pre test and post test. The research method used weak-experiment and involved 34 participants at senior high school students in Bandung-Indonesia. The research instruments for collecting data were environmental literacy test, observation sheets and questionnaire sheets for students. The analysis of data was quantitative descriptive. The results show that more than 79% of the students gave positive view for each field trip activity, i.e students activity during work (97%-100%); students activity during gather information (79%- 100%); students activity during exchange information with friend (82%-100%); and students interested to Biodiversity after field trip activity (85%-100%). Students gain knowledge about the diversity of animal vertebrate and its characteristics, the status and condition of animals, and the source of animal with the cases of animal diversity. The students environmental literacy tends to be moderate level based on test. Meanwhile, the average of the attitudes and action greater than the components of knowledge and cognitive skills.

Wang, Yen-Hsiang; Wei, Kathy Y.; Smolke, Christina D.

2013-01-01

A main objective of synthetic biology is to make the process of designing genetically-encoded biological systems more systematic, predictable, robust, scalable, and efficient. The examples of genetic systems in the field vary widely in terms of operating hosts, compositional approaches, and network complexity, ranging from a simple genetic switch to search-and-destroy systems. While significant advances in synthesis capabilities support the potential for the implementation of pathway- and genome-scale programs, several design challenges currently restrict the scale of systems that can be reasonably designed and implemented. Synthetic biology offers much promise in developing systems to address challenges faced in manufacturing, the environment and sustainability, and health and medicine, but the realization of this potential is currently limited by the diversity of available parts and effective design frameworks. As researchers make progress in bridging this design gap, advances in the field hint at ever more diverse applications for biological systems. PMID:23413816

To describe and compare the diverse organizational structures and funding mechanisms applied to advance HIV preventive vaccine research and development and to help explain and inform evolving infrastructures and collaborative funding models. On the basis of models that have been tried, improved or abandoned over three decades, the field seems to have settled into a relatively stable set of diverse initiatives, each with its own organizational signature. At the same time, this set of organizations is forging cross-organizational collaborations, which promise to acquire newly emergent beneficial properties. Strong motivation to expedite HIV vaccine R&D has driven a diversity of customized and inventive organizational approaches, largely government and foundation funded. Although no one approach has proven a panacea, the field has evolved into a constellation of often overlapping organizations that complement or reinforce one another. The Global HIV Vaccine Enterprise, a responsive, rapidly evolving loose infrastructure, is an innovative collaboration to catalyze that evolution.

Research on the development of tool use in children has often emphasized the cognitive bases of this achievement, focusing on the choice of an artifact, but has largely neglected its motor foundations. However, research across diverse fields, from evolutionary anthropology to cognitive neuroscience, converges on the idea that the actions that embody tool use are also critical for understanding its ontogenesis and phylogenesis. In this article, we highlight findings across these fields to show how a deeper examination of the act of tool using can inform developmental accounts and illuminate what makes human tool use unique.

Based on the literature data in CNKI, data mining and analysis technologies were used in this paper to describe the scientific research and development direction of Pharmacognosy in the last decade from the perspective of bibliometrics. The analysis of measured data revealed the core research institutions, excellent research teams, leading scholars, major research aspects and research progress in the field. Results showed that most of the scholars in the field were from colleges and institutions, accounting for 74.6% of the total research findings and forming a group of core scholars. In terms of frequency and timeliness of citation, pharmacognosy is a discipline in sustained growth and development since it mainly cites the literature in the other disciplines, absorbs and utilizes knowledge of the other disciplines. Over the last few years, molecular identification and genetic diversity have become the research hotspots in pharmacognosy, and the techniques and methods such as ISSR, RAPD, DNA barcoding and DNA molecular marker have been widely used.

Surface Plasmon Resonance (SPR) fiber sensor research has grown since the first demonstration over 20 year ago into a rich and diverse field with a wide range of optical fiber architectures, plasmonic coatings, and excitation and interrogation methods. Yet, the large diversity of SPR fiber sensor designs has made it difficult to understand the advantages of each approach. Here, we review SPR fiber sensor architectures, covering the latest developments from optical fiber geometries to plasmonic coatings. By developing a systematic approach to fiber-based SPR designs, we identify and discuss future research opportunities based on a performance comparison of the different approaches for sensing applications.

Objectives To identify research support strategies likely to be effective for strengthening the UK's dementia research landscape and ensuring a sustainable and competitive workforce. Design Interviews and qualitative analysis; systematic internet search to track the careers of 1500 holders of UK doctoral degrees in dementia, awarded during 1970–2013, to examine retention in this research field and provide a proxy profile of the research workforce. Setting and participants 40 interviewees based in the UK, whose primary role is or has been in dementia research (34 individuals), health or social care (3) or research funding (3). Interviewees represented diverse fields, career stages and sectors. Results While the UK has diverse strengths in dementia research, needs persist for multidisciplinary collaboration, investment in care-related research, supporting research-active clinicians and translation of research findings. There is also a need to better support junior and midlevel career opportunities to ensure a sustainable research pipeline and future leadership. From a sample of 1500 UK doctorate holders who completed a dementia-related thesis in 1970–2013, we identified current positions for 829 (55%). 651 (43% of 1500) could be traced and identified as still active in research (any field) and 315 (21%) as active in dementia research. Among recent doctoral graduates, nearly 70% left dementia research within 4–6 years of graduation. Conclusions A dementia research workforce blueprint should consider support for individuals, institutions and networks. A mix of policy interventions are needed, aiming to attract and retain researchers; tackle bottlenecks in career pathways, particularly at early and midcareer stages (eg, scaling-up fellowship opportunities, rising star programmes, bridge-funding, flexible clinical fellowships, leadership training); and encourage research networks (eg, doctoral training centres, succession and sustainability planning). Interventions should also address the need for coordinated investment to improve multidisciplinary collaboration; balanced research portfolios across prevention, treatment and care; and learning from evaluation.

2016-02-01

Coastal evaluation of key geochemical cycles is in strong need for thorough spatial data to address diverse topics. In many field studies we find that fixed station data taken from ship operations does not provide complete understanding of key research questions. In complicated systems where there is a need to integrate physical, chemical and biological parameters data taken from research vessels needs to be interpreted across large spatial areas. New technology in Unmanned Aircraft System (UAS) instrumentation coupled with ship board data can provide the thorough spatial data needed for a thorough evaluation of coastal sciences. This presentation will provide field data related to UAS application in two diverse environments. One study focuses on the flux of carbon dioxide and methane from Alaskan Arctic tundra and shallow Beaufort Sea coastal region to the atmosphere. In this study gas chemistry from samples is used to predict the relative fluxes to the atmosphere. A second study applies bio-optical analyses to differentiate between Gulf of Mexico coastal water column DOC and Lignin. This wide range of parameters in diverse ecosystems is selected to show current capability for application of UAS and the potential for understanding large scale questions about climate change and carbon cycling in coastal waters.

Structured, mentored research programs for high school and undergraduate students from underrepresented minority (URM) backgrounds are needed to increase the diversity of our nation’s biomedical research workforce. In particular, a robust pipeline of investigators from the communities disproportionately affected by the HIV epidemic is needed not only for fairness and equity but for insights and innovations to address persistent racial and ethnic disparities in new infections. We created the Summer HIV/AIDS Research Program (SHARP) at the San Francisco Department of Public Health for URM undergraduates as a 12-week program of hands-on research experience, one-on-one mentoring by a senior HIV investigator, didactic seminars for content and research methods, and networking opportunities. The first four cohorts (2012–2015) of SHARP gained research skills, built confidence in their abilities and self-identified as scientists. In addition, the majority of program alumni is employed in research positions and has been admitted to or is pursuing graduate degree programs in fields related to HIV prevention. While we await empirical studies of specific mentoring strategies at early educational stages, programs that engage faculty who are sensitive to the unique challenges facing diverse students and who draw lessons from established mentoring frameworks can help build an inclusive generation of HIV researchers.

Polishing the craft of genetic diversity creation in directed evolution.

PubMed

Tee, Kang Lan; Wong, Tuck Seng

2013-12-01

Genetic diversity creation is a core technology in directed evolution where a high quality mutant library is crucial to its success. Owing to its importance, the technology in genetic diversity creation has seen rapid development over the years and its application has diversified into other fields of scientific research. The advances in molecular cloning and mutagenesis since 2008 were reviewed. Specifically, new cloning techniques were classified based on their principles of complementary overhangs, homologous sequences, overlapping PCR and megaprimers and the advantages, drawbacks and performances of these methods were highlighted. New mutagenesis methods developed for random mutagenesis, focused mutagenesis and DNA recombination were surveyed. The technical requirements of these methods and the mutational spectra were compared and discussed with references to commonly used techniques. The trends of mutant library preparation were summarised. Challenges in genetic diversity creation were discussed with emphases on creating "smart" libraries, controlling the mutagenesis spectrum and specific challenges in each group of mutagenesis methods. An outline of the wider applications of genetic diversity creation includes genome engineering, viral evolution, metagenomics and a study of protein functions. The review ends with an outlook for genetic diversity creation and the prospective developments that can have future impact in this field. © 2013. Published by Elsevier Inc. All rights reserved.

The PM&R Journal Implements a Social Media Strategy to Disseminate Research and Track Alternative Metrics in Physical Medicine and Rehabilitation.

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.

Production of High-Value Nanoparticles via Biogenic Processes Using Aquacultural and Horticultural Food Waste

PubMed Central

Ghosh, Purabi R.; Fawcett, Derek; Sharma, Shashi B.; Poinern, Gerrard E. J.

2017-01-01

The quantities of organic waste produced globally by aquacultural and horticulture are extremely large and offer an attractive renewable source of biomolecules and bioactive compounds. The availability of such large and diverse sources of waste materials creates a unique opportunity to develop new recycling and food waste utilisation strategies. The aim of this review is to report the current status of research in the emerging field of producing high-value nanoparticles from food waste. Eco-friendly biogenic processes are quite rapid, and are usually carried out at normal room temperature and pressure. These alternative clean technologies do not rely on the use of the toxic chemicals and solvents commonly associated with traditional nanoparticle manufacturing processes. The relatively small number of research articles in the field have been surveyed and evaluated. Among the diversity of waste types, promising candidates and their ability to produce various high-value nanoparticles are discussed. Experimental parameters, nanoparticle characteristics and potential applications for nanoparticles in pharmaceuticals and biomedical applications are discussed. In spite of the advantages, there are a number of challenges, including nanoparticle reproducibility and understanding the formation mechanisms between different food waste products. Thus, there is considerable scope and opportunity for further research in this emerging field. PMID:28773212

Writing usable qualitative health research findings.

PubMed

Sandelowski, Margarete; Leeman, Jennifer

2012-10-01

Scholars in diverse health-related disciplines and specialty fields of practice routinely promote qualitative research as an essential component of intervention and implementation programs of research and of a comprehensive evidence base for practice. Remarkably little attention, however, has been paid to the most important element of qualitative studies--the findings in reports of those studies--and specifically to enhancing the accessibility and utilization value of these findings for diverse audiences of users. The findings in reports of qualitative health research are too often difficult to understand and even to find owing to the way they are presented. A basic strategy for enhancing the presentation of these findings is to translate them into thematic statements, which can then in turn be translated into the language of intervention and implementation. Writers of qualitative health research reports might consider these strategies better to showcase the significance and actionability of findings to a wider audience.

Geoscience Research at Storm Peak (GRASP) was designed to engage students from underrepresented groups through a partnership between Minority Serving Institutions and the University of Nevada, Reno (UNR). The program exposed the GRASP participants to potential careers in the geosciences, provided them with an authentic research experience at Storm Peak Laboratory (SPL), and gave them an opportunity to explore dynamic scenery. Undergraduate students from Howard University, Colorado State at Pueblo, Leman College, and SUNY Oneonta, gathered at SPL in June of 2008 via funding from the National Science Foundation Opportunity for Enhancing Diversity. The students reunited at Howard University in November to present the results of their research project. Throughout the year-long GRASP program students encountered the scientific process-creating a hypothesis, collecting and analyzing data, and presenting their results. Results from surveys, focus groups, and individual interviews will be discussed in this presentation.

Respect for cultural diversity in bioethics is an ethical imperative

PubMed Central

Chattopadhyay, Subrata; De Vries, Raymond

2012-01-01

The field of bioethics continues to struggle with the problem of cultural diversity: can universal principles guide ethical decision making, regardless of the culture in which those decisions take place? Or should bioethical principles be derived from the moral traditions of local cultures? Ten Have and Gordijn (2011) and Bracanovic (2011) defend the universalist position, arguing that respect for cultural diversity in matters ethical will lead to a dangerous cultural relativity where vulnerable patients and research subjects will be harmed. We challenge the premises of moral universalism, showing how this approach imports and imposes moral notions of Western society and leads to harm in non-western cultures. PMID:22955969

Mapping the evolution of entrepreneurship as a field of research (1990–2013): A scientometric analysis

PubMed Central

2018-01-01

This article applies scientometric techniques to study the evolution of the field of entrepreneurship between 1990 and 2013. Using a combination of topic mapping, author and journal co-citation analyses, and overlay visualization of new and hot topics in the field, this article makes important contribution to the entrepreneurship research by identifying 46 topics in the 24-year history of entrepreneurship research and demonstrates how they appear, disappear, reappear and stabilize over time. It also identifies five topics that are persistent across the 24-year study period––institutions and institutional entrepreneurship, innovation and technology management, policy and development, entrepreneurial process and opportunity, and new ventures––which I labeled as The Pentagon of Entrepreneurship. Overall, the analyses revealed patterns of convergence and divergence and the diversity of topics, specialization, and interdisciplinary engagement in entrepreneurship research, thus offering the latest insights on the state of the art of the field.

2017-12-01

With guidance and sufficient resources, undergraduates can drive the exploration of new research directions, lead high impact scientific products, and effectively communicate the value of science to the public. As mentors, we must recognize the strong contribution undergraduates make to the advancement of scientific understanding and their unique ability and desire to be transdisciplinary and to translate ideas into action. Our job is to be sure students have the resources and tools to successfully explore questions that they care about, not to provide or lead them towards answers we already have. The central goal of the Polaris Project is to advance understanding of climate change in the Arctic through an integrated research, training, and outreach program that has at its heart a research expedition for undergraduates to a remote field station in the Arctic. Our integrative approach to training provides undergraduates with strong intellectual development and they bring fresh perspectives, creativity, and a unique willingness to take risks on new ideas that have an energizing effect on research and outreach. Since the projects inception in summer 2008, we have had >90 undergraduates participate in high-impact field expeditions and outreach activities. Over the years, we have also been fortunate enough to attract an ethnically, racially, and culturally diverse group of students, including students from Puerto Rico, Hispanic-, African- and Native-Americans, members of the LGBT community, and first-generation college students. Most of these students have since pursued graduate degrees in ecology, and many have received NSF fellowships and Fulbright scholarships. One of our major goals is to increase the diversity of the scientific community, and we have been successful in our short-term goal of recruiting and retaining a diverse group of students. The goal of this presentation is to provide a description of the mentoring model at the heart of the Polaris Project, share narratives to highlight student research and outreach activities, and summarize the impact these experiences have had on our students over the years. We hope that sharing our perspective will spur a wider conversation on the role of a diverse group of undergraduate researchers as catalysts of both scientific advancement and effective communication.

[Evaluation and selection of species diversity index under grazing disturbance in alpine mea-dow].

2017-06-18

The research selected the plots of six grazing intensities in an alpine meadow in north-eastern Tibet Plateau in four years (2012-2015) and studied the relation between ten species diversity indexes, including two measured indexes (Richness and Abundance) in field and two indexes of each dominance, evenness, richness, integrated indexes, and grazing intensity as well as grazing time aiming at scientific selection of biodiversity index under grazing disturbance. The results indicated that the abundance was a better index than importance value to calculate biodiversity level because it was more sensitive to grazing disturbance. Dominance indexes, including Berger-Parker and Dominance, were not sensitive to grazing intensity and grazing time because they could not clarify the effect of grazing disturbance on dominant species in plant community. Evenness indexes, including Equitability and Evenness, had not relation with grazing intensity, however, the evenness index had a negative correlation with grazing time and it was not influenced by occasional species as well as the variation coefficient of species abundance. Hereby, the evenness index could be chosen for studying evenness change at temporal scale. Richness indexes, including Menhinick and Margalef, had no relation with grazing time, however, the Margalef index had a positive correlation with grazing intensity and the index was not influenced by occasional species. Integrated index, including Shannon and Simpson indexes, had no relation with grazing intensity, however, the Shannon index had a significant positive correlation with species richness and abundance and the index was not influenced by occasional species, and it significantly increased along grazing time. Hereby, Shannon index could be used as an index of studying plant species diversity in long-term. In ten diversity indexes, only the measured indexes in field, including richness and abundance, were signifi-cantly negatively correlated with grazing intensity, and positively correlated with grazing time, and the two indexes were not influenced by occasional species. Hereby, the combination of species richness and abundance mea-sured in field could be considered as the most important indexes for studying plant species diversity under grazing disturbance. Besides, the selection of biodiversity indexes must consider the spatial-temporal feature of grazing, diversity components and research purpose.

2012-01-01

Teams of scientists representing diverse disciplines are often brought together for purposes of better understanding and, ultimately, resolving urgent public health and environmental problems. Likewise, the emerging field of the science of team science draws on diverse disciplinary perspectives to better understand and enhance the processes and outcomes of scientific collaboration. In this supplement to the American Journal of Preventive Medicine, leading scholars in the nascent field of team science have come together with a common goal of advancing the field with new models, methods, and measures. This summary article highlights key themes reflected in the supplement and identifies several promising directions for future research organized around the following broad challenges: (1) operationalizing cross-disciplinary team science and training more clearly; (2) conceptualizing the multiple dimensions of readiness for team science; (3) ensuring the sustainability of transdisciplinary team science; (4) developing more effective models and strategies for training transdisciplinary scientists; (5) creating and validating improved models, methods, and measures for evaluating team science; and (6) fostering transdisciplinary cross-sector partnerships. A call to action is made to leaders from the research, funding, and practice sectors to embrace strategies of creativity and innovation in a collective effort to move the field forward, which may not only advance the science of team science but, ultimately, public health science and practice.

Impacts on soil invertebrates are an important aspect of environmental risk assessment and post-release monitoring of transgenic insect-resistant plants. The purpose of this study was to research and survey the effects of transgenic insect-resistant cottons that had been planted over 10 years on the abundance and community structure of soil invertebrates under field conditions. During 3 consecutive years (2006-2008), eight common taxa (orders) of soil invertebrates belonging to the phylum Arthropoda were investigated in two different transgenic cotton fields and one non-transgenic cotton field (control). Each year, soil samples were taken at four different growth stages of cotton (seedling, budding, boll forming and boll opening). Animals were extracted from the samples using the improved Tullgren method, counted and determined to the order level. The diversity of the soil fauna communities in the different fields was compared using the Simpson's, Shannon's diversity indices and evenness index. The results showed a significant sampling time variation in the abundance of soil invertebrates monitored in the different fields. However, no difference in soil invertebrate abundance was found between the transgenic cotton fields and the control field. Both sampling time and cotton treatment had a significant effect on the Simpson's, Shannon's diversity indices and evenness index. They were higher in the transgenic fields than the control field at the growth stages of cotton. Long-term cultivation of transgenic insect-resistant cottons had no significant effect on the abundance of soil invertebrates. Collembola, Acarina and Araneae could act as the indicators of soil invertebrate in this region to monitor the environmental impacts of transgenic plants in the future.

Heinrich, Michael; Frei Haller, Barbara; Leonti, Marco

2014-03-28

Mexico's extraordinarily rich cultural and floristic diversity has fascinated explorers and researchers ever since the "New World" was discovered for and by Europeans. For many decades, natural product research has been a very active field of research in Mexico, and there also are some ongoing ethnopharmacological research efforts. This review provides an overview and critical appraisal on some key developments in these fields and examples of medicinal plants used by indigenous communities that have become of great local importance in Mexican popular medicine. In this review, the focus is on plants with effects on the CNS, diabetes, metabolic syndrome, inflammatory processes, and gastrointestinal disorders. While some of the major food plants consumed worldwide originate from southern North America, only very few medicinal plants have become of major global importance. Opuntia species are now used increasingly to manage diabetes and metabolic syndrome and represent an example of a novel medicinal product/supplement. Undoubtedly, narcotic and mind-altering drugs both have received the widest scientific interest and have attracted considerable popular attention. The history of use of the indigenous Mexican Materia Medica in the context of research on local and popular resources specifically with regard to the diverse challenges in the context of studying the world's biodiversity and the development of comparative and semiquantitative ethnobotanical research methods is discussed herein. Natural product and ethnopharmacological research in Mexico seems to have been influenced by the political and societal developments originating from the Convention on Biological Diversity (CBD) and subsequent conventions, which have not yet had the desired effect of giving value to these local resources, as they might deserve. Their equitable and sustainable implementation remains a challenge. Natural product research and ethnopharmacology will play a key role in developing an adequate evidence base for such products derived from local and traditional knowledge in Mexico.

Building a Workforce for Future Health Systems: Reflections from Health Policy and Systems Research.

Javadi, Dena; Tran, Nhan; Ghaffar, Abdul

2018-05-24

The era of the Sustainable Development Goals calls for multidisciplinary research and intersectoral approaches to addressing health challenges. This presents a unique opportunity for multidisciplinary fields concerned with complex systems. Those working in system-oriented fields such as health policy and systems research (HPSR) and health services research must be forward-thinking in optimizing their collective ability to address these global challenges. The objective of this commentary was to share reflections on challenges and strategies in managing the HPSR workforce in order to stimulate dialogue and cross-learning across similar fields. The following strategies are discussed here: definitional clarity of expected competencies and coordination across HPS researchers, national investment in HPSR, institutional capacity for coproduction of knowledge across different types of actors, and participatory leadership. Creative approaches in training, financing, developing, and leading the diverse workforce required to strengthen health systems can pave the way for its full-time and part-time members to work together. © Health Research and Educational Trust.

Postdoctoral training programs are usually highly individualized arrangements between trainees and a limited number of senior mentors in their field, an approach that contrasts with current trends in public health education that promote interdisciplinary training to spur innovation. Herein, we describe an alternative model for postdoctoral training for a group of fellows from distinct disciplines. Fellows work with mentors from diverse fields to create a joint research project or a group of complementary projects, with the goal of developing a new device, intervention, or innovation to address a global health problem. The perceived benefits, challenges, and limitations of this team approach to interdisciplinary postdoctoral training are presented. PMID:27821694

Rites of consent: negotiating research participation in diverse cultures.

PubMed

Barrett, Robert J; Parker, Damon B

2003-04-01

The significance of informed consent in research involving humans has been a topic of active debate in the last decade. Much of this debate, we submit, is predicated on an ideology of individualism. We draw on our experiences as anthropologists working in Western and non Western (Iban) health care settings to present ethnographic data derived from diverse scenes in which consent is gained. Employing classical anthropological ritual theory, we subject these observational data to comparative analysis. Our article argues that the individualist assumptions underlying current bioethics guidelines do not have universal applicability, even in Western research settings. This is based on the recognition that the social world is constitutive of personhood in diverse forms, just one of which is individualistic. We submit that greater attention must be paid to the social relations the researcher inevitably engages in when conducting research involving other people, be this in the context of conventional medical research or anthropological field work. We propose, firstly, that the consenting process continues throughout the life of any research project, long after the signature has been secured, and secondly, that both group and individual dimensions of consent, and the sequence in which these dimensions are addressed, should be carefully considered in all cases where consent is sought.

Feeling the beat: the meaning of rap music for ethnically diverse Midwestern college students--a phenomenological study.

PubMed

Iwamoto, Derek K; Creswell, John; Caldwell, Leon

2007-01-01

Despite its national and international appeal, rap is considered one of the most controversial of music genres. Given the political charge it generates, rap music has spawned research across the social and health sciences. The majority of the research has investigated its impact on African Americans. Further, the research has tended to focus on negative aspects of the music; there has been a dearth of in-depth qualitative studies that explore how rap impacts the listener. Our phenomenological study explores that impact on ethnically diverse college students. Results indicate a profound psychological and educational effect and the discussion goes on to highlight the potential and innovative ways rap music can be utilized with adolescents in fields such as education, risk reduction programs, and counseling psychology.

Magnetic maps in animals: nature's GPS.

PubMed

Lohmann, Kenneth J; Lohmann, Catherine M F; Putman, Nathan F

2007-11-01

Diverse animals detect the Earth's magnetic field and use it as a cue in orientation and navigation. Most research on magnetoreception has focused on the directional or ;compass' information that can be extracted from the Earth's field. Because the field varies predictably across the surface of the globe, however, it also provides a potential source of positional or 'map' information, which some animals use to steer themselves along migratory pathways or to navigate toward specific target areas. The use of magnetic positional information has been demonstrated in several diverse animals including sea turtles, spiny lobsters, newts and birds, suggesting that such systems are phylogenetically widespread and can function over a wide range of spatial scales. These ;magnetic maps' have not yet been fully characterized. They may be organized in several fundamentally different ways, some of which bear little resemblance to human maps, and they may also be used in conjunction with unconventional navigational strategies.

The year 2016 marks the 60th anniversary of the Joint Institute for Nuclear Research (JINR) in Dubna, an international intergovernmental organization for basic research in the fields of elementary particles, atomic nuclei, and condensed matter. Highly productive advances over this long road clearly show that the international basis and diversity of research guarantees successful development (and maintenance) of fundamental science. This is especially important for experimental research. In this review, the most significant achievements are briefly described with an attempt to look into the future (seven to ten years ahead) and show the role of JINR in solution of highly important problems in elementary particle physics, which is a fundamental field of modern natural sciences. This glimpse of the future is full of justified optimism.

2016-01-01

The population of students who are deaf or hard of hearing is becoming more culturally and/or linguistically diverse. However, there is a paucity of practitioner literature and research available to professionals and families to guide decision making about daily practices with these students and their families. The study identified factors that contribute to the success of students who are deaf or hard of hearing and from culturally and/or linguistically diverse backgrounds who receive the majority of their education in inclusive settings. Students were recruited from two schools in two school districts in a western state. Students, educators, interpreters, and parents participated in individual in-depth, semi-structured interviews. Observations of the students were also done. Analysis of the data included coding the transcribed interviews and the field notes to identify common themes. Seven themes emerged and are reported. Recommendations for future research are provided.

The questions that chemical oceanographers prioritize over the coming decades, and the methods we use to address these questions, will define our field's contribution to 21st century science. In recognition of this, the U.S. National Science Foundation and National Oceanic and Atmospheric Administration galvanized a community effort (the Chemical Oceanography MEeting: A BOttom-up Approach to Research Directions, or COME ABOARD) to synthesize bottom-up perspectives on selected areas of research in Chemical Oceanography. Representing only a small subset of the community, COME ABOARD participants did not attempt to identify targeted research directions for the field. Instead, we focused on how best to foster diverse research in Chemical Oceanography, placing emphasis on the following themes: strengthening our core chemical skillset; expanding our tools through collaboration with chemists, engineers, and computer scientists; considering new roles for large programs; enhancing interface research through interdisciplinary collaboration; and expanding ocean literacy by engaging with the public. For each theme, COME ABOARD participants reflected on the present state of Chemical Oceanography, where the community hopes to go and why, and actionable pathways to get there. A unifying concept among the discussions was that dissimilar funding structures and metrics of success may be required to accommodate the various levels of readiness and stages of knowledge development found throughout our community. In addition to the science, participants of the concurrent Dissertations Symposium in Chemical Oceanography (DISCO) XXV, a meeting of recent and forthcoming Ph.D. graduates in Chemical Oceanography, provided perspectives on how our field could show leadership in addressing long-standing diversity and early-career challenges that are pervasive throughout science. Here we summarize the COME ABOARD Meeting discussions, providing a synthesis of reflections and perspectives on the field.

The recruitment of culturally and linguistically diverse students to graduate programs is critical to the overall growth and development of school psychology as a field. Program websites serve as an effective recruitment tool for attracting prospective students, yet there is limited research on how school psychology programs use their websites to recruit diverse students. The purpose of this study was to evaluate whether school psychology program websites include sufficient levels of diversity-related content critical for attracting diverse applicants. The website content of 250 professional psychology programs (165 school psychology training programs and 85 clinical and counseling psychology programs) were examined for the presence of themes of diversity and multiculturalism that prospective racially/ethnically and linguistically diverse students deem important for selecting a graduate program. Results indicated that school psychology programs had less diversity-related content on their program's website relative to clinical and counseling psychology programs.' Implications for improving recruitment of racially/ethnically and linguistically diverse students through websites are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Genetic diversity enhances the resistance of a seagrass ecosystem to disturbance.

PubMed

Hughes, A Randall; Stachowicz, John J

2004-06-15

Motivated by recent global reductions in biodiversity, empirical and theoretical research suggests that more species-rich systems exhibit enhanced productivity, nutrient cycling, or resistance to disturbance or invasion relative to systems with fewer species. In contrast, few data are available to assess the potential ecosystem-level importance of genetic diversity within species known to play a major functional role. Using a manipulative field experiment, we show that increasing genotypic diversity in a habitat-forming species (the seagrass Zostera marina) enhances community resistance to disturbance by grazing geese. The time required for recovery to near predisturbance densities also decreases with increasing eelgrass genotypic diversity. However, there is no effect of diversity on resilience, measured as the rate of shoot recovery after the disturbance, suggesting that more rapid recovery in diverse plots is due solely to differences in disturbance resistance. Genotypic diversity did not affect ecosystem processes in the absence of disturbance. Thus, our results suggest that genetic diversity, like species diversity, may be most important for enhancing the consistency and reliability of ecosystems by providing biological insurance against environmental change.

Assessing Wild Bee Biodiversity in Cranberry Agroenvironments: Influence of Natural Habitats.

PubMed

Gervais, Amélie; Fournier, Valérie; Sheffield, Cory S; Chagnon, Madeleine

2017-08-01

The conservation of bee populations for pollination in agricultural landscapes has attracted a lot of recent research interest, especially for crop industries undergoing expansion to meet increased production demands. In Canada, much growth has been occurring with commercial cranberry production, a field crop which is largely dependent on bee pollination. Wild bee pollinators could be negatively impacted by losses of natural habitat surrounding cranberry fields to accommodate increased production, but growers have little insight on how to manage their lands to maximize the presence of wild bees. Here, we described a 2-yr study where bee diversity and species composition were investigated to better understand the dynamic between natural habitat and cranberry fields. Bees were sampled using pan-traps and hand netting both within cranberry fields and in one of the three adjacent natural habitat types once a week during the crop flowering period. We found that bee community composition among cranberry fields did not differ based on the respective adjacent habitat type, but fields bordered by meadows were marginally less diverse than fields bordered by forest. As one would expect, field and natural habitat communities differed in terms of species composition and species richness. There was no evidence that one type of natural habitat was more favorable for the bees than another. Future agrobiodiversity studies should simultaneously examine bee diversity comprised in both crop fields and adjacent natural environments to better understand the species dynamics essential to the preservation of pollination services. © The Authors 2017.

Theory Into Practice: Applying Lessons Learned From Retention Studies To Build A Diverse Graduate Community

NASA Astrophysics Data System (ADS)

Gross, N. A.; Lopez, R.; Hughes, W. J.

2008-03-01

The Center for Integrated Space Weather Modeling (CISM) is a nationally distributed research program that focuses its activities around building a comprehensive physics-based numerical simulation model that describes the space environment from the Sun to the Earth. As a Science and Technology Center (STC) funded by the National Science Foundation (NSF), CISM is committed to training the next generation of space physicists and imbuing them with an understanding of the Sun & Earth as a system. CISM has fostered a thriving, diverse community of graduate students actively engaged in CISM research and related activities. The Center's goal for these students is for them to not only graduate with a strong understanding of their research field, but also with knowledge of related research areas and relationships with other young professionals who work in those areas. To meet this goal, CISM sponsors graduate activities such as graduate retreats, a graduate online community, graduate video conferences, and provides professional interactions with leaders in the field. These activities are designed to develop peer to peer relationships and are exactly the sort of activities that will engage new students in the community. This paper will describe these activities and show that they are consistent with the needs of graduate students as identified in the limited literature on persistence in graduate education. These activities are also consistent with the conclusions about the well studied problem of retention at the undergraduate level. Activities that help to increase retention will also increase the value of diversity recruitment programs, since it will increase the likeliness that these students will persist to graduation.

Spontaneous generation of singularities in paraxial optical fields.

PubMed

Aiello, Andrea

2016-04-01

In nonrelativistic quantum mechanics, the spontaneous generation of singularities in smooth and finite wave functions is a well understood phenomenon also occurring for free particles. We use the familiar analogy between the two-dimensional Schrödinger equation and the optical paraxial wave equation to define a new class of square-integrable paraxial optical fields that develop a spatial singularity in the focal point of a weakly focusing thin lens. These fields are characterized by a single real parameter whose value determines the nature of the singularity. This novel field enhancement mechanism may stimulate fruitful research for diverse technological and scientific applications.

2017-01-01

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.

The aim of the research activity was to increase our understanding of solar activity through data analysis, theoretical analysis, and computer modeling. Because the research subjects were diverse and many researchers were supported by this grant, a select few key areas of research are described in detail. Areas of research include: (1) energy storage and force-free magnetic field; (2) energy release and particle acceleration; (3) radiation by nonthermal electrons; (4) coronal loops; (5) flare classification; (6) longitude distributions of flares; (7) periodicities detected in the solar activity; (8) coronal heating and related problems; and (9) plasma processes.

Predator community structure and trophic linkage strength to a focal prey.

PubMed

Lundgren, Jonathan G; Fergen, Janet K

2014-08-01

Predator abundance and community structure can affect the suppression of lower trophic levels, although studies of these interactions under field conditions are relatively few. We investigated how the frequency of consumption (measured using PCR-based gut content analysis) is affected by predator abundance, community diversity and evenness under realistic conditions. Soil arthropod communities in sixteen maize fields were measured (number of predators, diversity [Shannon H] and evenness [J]), and predator guts were searched for DNA of the focal subterranean herbivore, the corn rootworm (Diabrotica virgifera). Predator abundance and diversity were positively correlated with trophic linkage strength (the proportion positive for rootworm DNA), although the latter characteristic was not significantly so. The diversity and evenness of the predator community with chewing mouthparts were strongly correlated with their linkage strength to rootworms, whereas the linkage strength of fluid-feeding predators was unaffected by their community characteristics. Within this community, chewing predators are more affected by the rootworm's hemolymph defence. This research clearly shows that predator abundance and diversity influence the strength of a community's trophic linkage to a focal pest and that these community characteristics may be particularly important for less palatable or protected prey species. We also make the case for conserving diverse and abundant predator communities within agroecosystems as a form of pest management. Published 2014.

Reconcilable differences? Human diversity, cultural relativity, and sense of community.

PubMed

Townley, Greg; Kloos, Bret; Green, Eric P; Franco, Margarita M

2011-03-01

Sense of community (SOC) is one of the most widely used and studied constructs in community psychology. As proposed by Sarason in (The Psychological sense of community: prospects for a community psychology, Jossey-Bass, San Francisco, 1974), SOC represents the strength of bonding among community members. It is a valuable component of community life, and it has been linked to positive mental health outcomes, citizen participation, and community connectedness. However, promotion of SOC can become problematic in community psychology praxis when it conflicts with other core values proposed to define the field, namely values of human diversity, cultural relativity, and heterogeneity of experience and perspective. Several commentators have noted that promotion of SOC can conflict with multicultural diversity because it tends to emphasize group member similarity and appears to be higher in homogeneous communities. In this paper, we introduce the idea of a community-diversity dialectic as part of praxis and research in community psychology. We argue that systematic consideration of cultural psychology perspectives can guide efforts to address a community-diversity dialectic and revise SOC formulations that ultimately will invigorate community research and action. We provide a working agenda for addressing this dialectic, proposing that systematic consideration of the creative tension between SOC and diversity can be beneficial to community psychology.

Earth Observations taken by the Expedition 17 Crew

ISS017-E-006184 (3 May 2008) --- NASA Ames Research Center, Moffett Field, CA is featured in this image photographed by an Expedition 17 crewmember on the International Space Station. This view illustrates the diverse built environment surrounding NASA's Ames Research Center, or ARC located at the southernmost end of the San Francisco Bay. Founded in 1939 as an aircraft research laboratory, Ames became a NASA facility in 1958. Its original aircraft research focus was enhanced by the adjacent Moffett Field -- an active Naval Air Station until 1994 and original home of the Navy dirigible U.S.S. Macon. The large hanger for docking the U.S.S. Macon is still present at Moffett Field, and is visible in this image (center). Today, NASA ARC includes the former Naval Air Station, and continues its focus on aeronautics in addition to nanotechnology, information technology, fundamental space biology, biotechnology, thermal protection systems, and human factors research. Land use and land cover in the southern San Francisco Bay area is a diverse mix of industrial, institutional, and residential patterns. Industrial lots -- characterized by lack of green vegetation and large buildings with highly reflective white rooftops -- border NASA ARC to the west, east, and south. The city of Mountain View directly to the south appears as a dense gray-brown network of streets and residential properties with interspersed green parks. The northern boundary of NASA ARC consists of former salt ponds in the process of being returned to tidal wetlands (right). Drainage channels that predate the salt pond levees are visible at right.

Measuring and Monitoring Biological Diversity: Standard Methods for Mammals provides a comprehensive manual for designing and implementing inventories of mammalian biodiversity anywhere in the world and for any group, from rodents to open-country grazers. The book emphasizes formal estimation approaches, which supply data that can be compared across habitats and over time. Beginning with brief natural histories of the twenty-six orders of living mammals, the book details the field techniques—observation, capture, and sign interpretation—appropriate to different species. The contributors provide guidelines for study design, discuss survey planning, describe statistical techniques, and outline methods of translating field data into electronic formats. Extensive appendixes address such issues as the ethical treatment of animals in research, human health concerns, preserving voucher specimens, and assessing age, sex, and reproductive condition in mammals.Useful in both developed and developing countries, this volume and the Biological Diversity Handbook Series as a whole establish essential standards for a key aspect of conservation biology and resource management.

Weber, Bettina; Belnap, Jayne; Buedel, Burkhard

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.

CAISE: A NSF Resource Center for Informal Science Education

NASA Astrophysics Data System (ADS)

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.

Applying remote sensing expertise to crop improvement: progress and challenges to scale up high throughput field phenotyping from research to industry

Digital and image analysis technologies in greenhouses have become commonplace in plant science research and started to move into the plant breeding industry. However, the core of plant breeding work takes place in fields. We will present successive technological developments that have allowed the migration and application of remote sensing approaches at large into the field of crop genetics and physiology research, with a number of projects that have taken place in France. These projects have allowed us to develop combined sensor plus vector systems, from tractor mounted and UAV (unmanned aerial vehicle) mounted spectroradiometry to autonomous vehicle mounted spectroradiometry, RGB (red-green-blue) imagery and Lidar. We have tested these systems for deciphering the genetics of complex plant improvement targets such as the robustness to nitrogen and water deficiency of wheat and maize. Our results from wheat experiments indicate that these systems can be used both to screen genetic diversity for nitrogen stress tolerance and to decipher the genetics behind this diversity. We will present our view on the next critical steps in terms of technology and data analysis that will be required to reach cost effective implementation in industrial plant breeding programs. If this can be achieved, these technologies will largely contribute to resolving the equation of increasing food supply in the resource limited world that lies ahead.

Managing equality and cultural diversity in the health workforce.

PubMed

Hunt, Beverley

2007-12-01

This article offers practical strategies to managers and others for supporting overseas trained nurses and managing cultural diversity in the health workforce. Widespread nursing shortages have led managers to recruit nurses from overseas, mainly from developing countries. This paper draws on evidence from the Researching Equal Opportunities for Internationally Recruited Nurses and Other Health Professionals study reported elsewhere in this issue, which indicates that overseas trained nurses encountered widespread discriminatory practices including an overuse of complaints and grievances against them. The researchers also found that the overseas trained nurses responded to their experiences by using various personal strategies to resist or re-negotiate and overcome such discriminatory practices. A research workshop was held in June 2005 at the midpoint of the Researching Equal Opportunities for Internationally Recruited Nurses and Other Health Professionals study. Twenty-five participants attended the workshop. They were the Researching Equal Opportunities for Internationally Recruited Nurses and Other Health Professionals study researchers, advisory group members, including the author of this paper and other researchers in the field of migration. The overall aim of the workshop was to share emerging research data from the Researching Equal Opportunities for Internationally Recruited Nurses and Other Health Professionals and related studies. The final session of the workshop on which this paper is based, was facilitated by the author, with the specific aim of asking the participants to discuss and determine the challenges to managers when managing a culturally diverse workforce. The discussion yielded four main themes collated by the author from which a framework of strategies to facilitate equality and cultural diversity management of the healthcare workers may be developed. The four themes are: assumptions and expectations; education and training to include cultural sensitivity, equality and human rights; performance management; and transparent human resource management processes. Managing a racially and culturally diverse workforce is complex and challenging for managers. There are no ready-made tools to show them how to do so. Achieving effective management of a culturally diverse workforce comes from an intrinsic motivation to develop the cultural competence to engage with them. This article, together with others in this special issue, provides a springboard for moving this agenda on. It offers managers a framework of themes, which they can draw on to develop their own best practice for managing racial equality and cultural diversity in the health workforce.

MARS-OZ - A Design for a Simulated Mars Base in the Australian Outback

NASA Astrophysics Data System (ADS)

Willson, D.; Clarke, J. D. A.; Murphy, G.

Mars Society Australia has developed the design of a simulated Mars base, MARS-OZ, for deployment in outback Australia. MARS-OZ will provide a platform for a diverse range of Mars analogue research in Australia. The simulated base consists of two mobile modules whose dimensions and shape approximate those of horizontally landed bent biconic spacecraft described in an earlier paper. The modules are designed to support field engineering, robotics, architectural, geological, biological and human factors research at varying levels of simulation fidelity. Non-Mars related research can also be accommodated, for example general field geology and biology, and engineering research associated with sustainable, low impact architecture. Crews of up to eight can be accommodated. In addition to its research function, the base also will serve as a centre of space education and outreach activities. The prime site for the MARS-OZ simulated base is located in the northern Flinders Ranges near Arkaroola in South Australia. This region contains many features that provide useful scientific analogues to known or possible past and present conditions on Mars from both a geological and biological perspective. The features will provide a wealth of study opportunities for crews. The very diverse terrain and regolith materials will provide ideal opportunities to field trial a range of equipment, sensors and exploration strategies. If needed, the prime site can be secured from casual visitors, allowing research into human interaction in isolation. Despite its relative isolation, the site is readily accessible by road and air from major Australian centres. This paper provides description of the configuration, design and construction of the proposed facility, its interior layout, equipment and systems fitouts, a detailed cost estimate, and its deployment. We estimate that the deployment of MARS-OZ could occur within nine months of securing funding.

To identify research support strategies likely to be effective for strengthening the UK's dementia research landscape and ensuring a sustainable and competitive workforce. Interviews and qualitative analysis; systematic internet search to track the careers of 1500 holders of UK doctoral degrees in dementia, awarded during 1970-2013, to examine retention in this research field and provide a proxy profile of the research workforce. 40 interviewees based in the UK, whose primary role is or has been in dementia research (34 individuals), health or social care (3) or research funding (3). Interviewees represented diverse fields, career stages and sectors. While the UK has diverse strengths in dementia research, needs persist for multidisciplinary collaboration, investment in care-related research, supporting research-active clinicians and translation of research findings. There is also a need to better support junior and midlevel career opportunities to ensure a sustainable research pipeline and future leadership. From a sample of 1500 UK doctorate holders who completed a dementia-related thesis in 1970-2013, we identified current positions for 829 (55%). 651 (43% of 1500) could be traced and identified as still active in research (any field) and 315 (21%) as active in dementia research. Among recent doctoral graduates, nearly 70% left dementia research within 4-6 years of graduation. A dementia research workforce blueprint should consider support for individuals, institutions and networks. A mix of policy interventions are needed, aiming to attract and retain researchers; tackle bottlenecks in career pathways, particularly at early and midcareer stages (eg, scaling-up fellowship opportunities, rising star programmes, bridge-funding, flexible clinical fellowships, leadership training); and encourage research networks (eg, doctoral training centres, succession and sustainability planning). Interventions should also address the need for coordinated investment to improve multidisciplinary collaboration; balanced research portfolios across prevention, treatment and care; and learning from evaluation.

2010-01-01

In December 2008, the National Institutes of Health (NIH) sponsored the first NIH Summit showcasing its investment and contribution to health disparities research and unveiling a framework for moving this important field forward. The Summit, titled “The Science of Eliminating Health Disparities,” drew on extensive experience of experts leading health disparities research transformation in diverse fields. The Summit also provided a historic educational opportunity to contribute to health care reform. The theme, addressing disparities through integration of science, practice, and policy, introduced a paradigm for advancing research through transformational, translational, and transdisciplinary research. Engaging active participation throughout the Summit generated recommendations bridging science, practice, and policy, including action on social determinants of health, community engagement, broad partnerships, capacity-building, and media outreach.

Poor communication between academic researchers and wildlife managers limits conservation progress and innovation. As a result, input from overlapping fields, such as animal behaviour, is underused in conservation management despite its demonstrated utility as a conservation tool and countless papers advocating its use. Communication and collaboration across these two disciplines are unlikely to improve without clearly identified management needs and demonstrable impacts of behavioural-based conservation management. To facilitate this process, a team of wildlife managers and animal behaviour researchers conducted a research prioritisation exercise, identifying 50 key questions that have great potential to resolve critical conservation and management problems. The resulting agenda highlights the diversity and extent of advances that both fields could achieve through collaboration. Copyright © 2016 The Authors. Published by Elsevier Ltd..

The rapid development of genome modification technology has provided many great benefits in diverse areas of research and industry. Genome modification technologies have also been actively used in a variety of research areas and fields of industry in avian species. Transgenic technologies such as lentiviral systems and piggyBac transposition have been used to produce transgenic birds for diverse purposes. In recent years, newly developed programmable genome editing tools such as transcription activator-like effector nuclease (TALEN) and clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (CRISPR/Cas9) have also been successfully adopted in avian systems with primordial germ cell (PGC)-mediated genome modification. These genome modification technologies are expected to be applied to practical uses beyond system development itself. The technologies could be used to enhance economic traits in poultry such as acquiring a disease resistance or producing functional proteins in eggs. Furthermore, novel avian models of human diseases or embryonic development could also be established for research purposes. In this review, we discuss diverse genome modification technologies used in avian species, and future applications of avian biotechnology.

Graduate students in the astronomy department at the University of Washington began the Pre-Major in Astronomy Program (Pre-MAP) after recognizing that underrepresented students in STEM fields are not well retained after their transition from high school. Pre-MAP is a research and mentoring program that begins with a keystone seminar where they learn astronomical research techniques that they apply to research projects conducted in small groups. Students also receive one-on-one mentoring and peer support for the duration of the academic year and beyond. Successful Pre-MAP students have declared astronomy and physics majors, expanded their research projects beyond the fall quarter, presented posters at the UW Undergraduate Research Symposium, and received research fellowships and summer internships. Here we examine the success of the program in attracting underrepresented minorities and in facilitating better STEM retention and academic performance among incoming UW students. We use the University of Washington Student Database to study both the performance of Pre-MAP students and the overall UW student body over the past 8 years. We show that Pre-MAP students are generally more diverse than the overall UW population and also come in with a variety of different math backgrounds, which we show to be an important factor on STEM performance for the overall UW population. We find that that Pre-MAP students are both more academically successful and more likely to graduate in STEM fields than their UW peers, regardless of initial math placement.

Biodiversity evaluation in tropical agricultural systems - How will rubber cultivation and land use change effect species diversity in SW China

Cotter, M.; Grenz, J.; Sauerborn, J.

2012-04-01

The Greater Mekong Subregion is a known hotspot of biodiversity, which faces drastic changes due to human impact particularly with regard to infrastructure and economy. Within the framework of the Sino-German research project "Living Landscapes China" (LILAC), we have developed a biodiversity evaluation tool based on the combination of approaches from landscape ecology with detailed empirical data on species diversity and habitat characteristics of tropical plant and arthropod communities in a Geographical Information System. We use field ecological data to assess different spatial and qualitative aspects of the diversity and spatial distribution of species throughout the research area, a watershed in south-western Yunnan province, PR China. In addition, scenarios on the impact of land use change have been analyzed and compared in order to highlight the implications these possible future scenarios would have on species diversity within the research area. The aim of the presented tool is to provide scientists and policy makers who have to evaluate the consequences of scenarios of future land use with information on the current and likely future state of biodiversity in their research area or administrative region. This will enable them to assess the likely impacts of land use changes on structural and ecological diversity and allow for informed land use planning. The methodology developed for this tool can also be applied outside of the Greater Mekong Subregion, as the model structure allows for an easy adaption to other research areas and challenges, be it oil palm production in Southeast Asia or small scale farming in central Africa or the Amazon basin.

Application of nanotechnology and nanomaterials is not new in the field of design, but a recent trend of extensive use of nanomaterials in product and/or workplace design is drawing attention of design researchers all over the world. In the present paper, an attempt has been made to describe the diverse use of nanomaterials in product and workplace design with special emphasis on ergonomics (occupational health and safety; thermo-regulation and work efficiency, cognitive interface design; maintenance of workplace, etc.) to popularise the new discipline 'nanoergonomics' among designers, design users and design researchers. Nanoergonomics for sustainable product and workplace design by minimising occupational health risks has been felt by the authors to be an emerging research area in coming years. Use of nanomaterials in the field of design ergonomics is less explored till date. In the present review, an attempt has been made to extend general awareness among ergonomists/designers about applications of nanomaterials/nanotechnology in the field of design ergonomics and about health implications of nanomaterials during their use.

We encourage laboratory animal science to address the challenges and to build on the strengths that personal diversity brings to our field and workplaces. Diversity is already becoming increasingly relevant in the workplace and the laboratory animal science field. By addressing issues related to diversity, laboratory animal science could benefit and potentially fulfill its goals more successfully. To date, diversity has received minimal attention from the field as a whole. However, many individuals, workplaces, and institutions in industry, academia, and the uniformed services that are intimately involved with the field of laboratory animal science are actively addressing issues concerning diversity. This article describes some of these programs and activities in industry and academia. Our intention is that this article will provide useful examples of inclusion-promoting activities and prompt further initiatives to address diversity awareness and inclusion in laboratory animal science.

Species Pool Functional Diversity Plays a Hidden Role in Generating β-Diversity.

PubMed

Patrick, Christopher J; Brown, Bryan L

2018-05-01

Functional trait diversity is used as a way to infer mechanistic processes that drive community assembly. While functional diversity within communities is often viewed as a response variable, here we present and test a framework for how functional diversity among taxa in the regional species pool drives the assembly of communities among habitats. We predicted that species pool functional diversity should work with environmental heterogeneity to drive β-diversity. We tested these predictions by modeling empirical patterns in invertebrate communities from 570 streams in 52 watersheds. Our analysis of the field data provided strong support for the inclusion of both functional diversity and environmental heterogeneity in the models, and our predictions were supported when the community was analyzed all together. However, analyses within individual functional feeding guilds revealed strong context dependency in the relative importance of functional diversity, γ-richness, and environmental heterogeneity to β-diversity. We interpret the results to mean that functional diversity can play an important role in driving β-diversity; however, within guilds the nature of interspecific interactions and species pool size complicate the relationship. Future research should test this conceptual model across different ecosystems and in experimental settings using metacommunity mesocosms to enhance our understanding of the role that functional variation plays in generating spatial biodiversity patterns.

Biology is increasingly becoming a data-intensive science with the recent progress of the omics fields, e.g. genomics, transcriptomics, proteomics and metabolomics. The species-metabolite relationship database, KNApSAcK Core, has been widely utilized and cited in metabolomics research, and chronological analysis of that research work has helped to reveal recent trends in metabolomics research. To meet the needs of these trends, the KNApSAcK database has been extended by incorporating a secondary metabolic pathway database called Motorcycle DB. We examined the enzyme sequence diversity related to secondary metabolism by means of batch-learning self-organizing maps (BL-SOMs). Initially, we constructed a map by using a big data matrix consisting of the frequencies of all possible dipeptides in the protein sequence segments of plants and bacteria. The enzyme sequence diversity of the secondary metabolic pathways was examined by identifying clusters of segments associated with certain enzyme groups in the resulting map. The extent of diversity of 15 secondary metabolic enzyme groups is discussed. Data-intensive approaches such as BL-SOM applied to big data matrices are needed for systematizing protein sequences. Handling big data has become an inevitable part of biology.

The body of work relating to the gut microbiota of fish is dwarfed by that on humans and mammals. However, it is a field that has had historical interest and has grown significantly along with the expansion of the aquaculture industry and developments in microbiome research. Research is now moving quickly in this field. Much recent focus has been on nutritional manipulation and modification of the gut microbiota to meet the needs of fish farming, while trying to maintain host health and welfare. However, the diversity amongst fish means that baseline data from wild fish and a clear understanding of the role that specific gut microbiota play is still lacking. We review here the factors shaping marine fish gut microbiota and highlight gaps in the research.

Lessons and Perspectives on Balancing Research and Diversity-Oriented Service

NASA Astrophysics Data System (ADS)

Emanuel, R. E.

2012-12-01

Diversity among scientists is necessary to bring together the range of personal and professional perspectives required to address many grand challenges of research in the earth and environmental sciences. Despite gains in recent decades, African Americans and American Indians remain severely under-represented at the graduate level in the environmental sciences, posing an impediment to ethnic diversity in the ranks of professional scientists. For example, the US National Science Foundation reported that in one recent year African Americans received 1,041 (3%) and American Indians received 120 (0.4%) of the 33,284 science and engineering doctoral degrees granted in the US. These fractions are smaller than African American and American Indian representation among bachelor's degree recipients, and they are smaller than representation in the general US population. Lessons from multiple disciplines (chemistry, medicine and geoscience) suggest that group learning, longitudinal mentoring and networking opportunities are critical elements in the retention of under-represented minority students and their conversion to professionals in scientific fields. With this in mind, I have worked to incorporate these elements into my own research program, which moved recently from a predominantly undergraduate institution to a research extensive university. I discuss the outcomes, successes and challenges of a recent project engaging 14 students and 5 faculty mentors from 6 institutions, including 2 HBCUs, in a yearlong study of secondary ecosystem succession in North Carolina. I frame this discussion in the general context of my own experience, as an American Indian academic, balancing diversity-related service and more traditionally recognized forms of scholarship (i.e. teaching and research) at both predominantly undergraduate and research extensive universities.

A Resource Center for Informal Science Education

NASA Astrophysics Data System (ADS)

Dickow, B.

2011-12-01

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, all sectors of the informal science education field. 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 AGU'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.

Cultural safety, diversity and the servicer user and carer movement in mental health research.

PubMed

Cox, Leonie G; Simpson, Alan

2015-12-01

This study will be of interest to anyone concerned with a critical appraisal of mental health service users' and carers' participation in research collaboration and with the potential of the postcolonial paradigm of cultural safety to contribute to the service user research (SUR) movement. The history and nature of the mental health field and its relationship to colonial processes provokes a consideration of whether cultural safety could focus attention on diversity, power imbalance, cultural dominance and structural inequality, identified as barriers and tensions in SUR. We consider these issues in the context of state-driven approaches towards SUR in planning and evaluation and the concurrent rise of the SUR movement in the UK and Australia, societies with an intimate involvement in processes of colonisation. We consider the principles and motivations underlying cultural safety and SUR in the context of the policy agenda informing SUR. We conclude that while both cultural safety and SUR are underpinned by social constructionism constituting similarities in principles and intent, cultural safety has additional dimensions. Hence, we call on researchers to use the explicitly political and self-reflective process of cultural safety to think about and address issues of diversity, power and social justice in research collaboration. © 2015 John Wiley & Sons Ltd.

Enhancing Diversity In The Geosciences; Intensive Field Experience In USA And Mexico For Middle And High School Teachers Serving Large Hispanic Populations.

Leal-Bautista, R. M.; Kitts, K. B.; Velazquez Oliman, G.; Perry, E. C.

2008-12-01

To encourage Hispanic participation and enrolment in the geosciences and ultimately enhance diversity within the discipline, we recruited ten middle and high school science teachers serving large Hispanic populations (60-97%) for a paid three-week field experience supported by an NSF Opportunities for Enhancing Diversity in the Geosciences grant. In 2006, the field experiences focused on volcanic events and the water problems of the Central part of Mexico. In 2008, the field experiences focused on karstic and hydrogeological conditions of the Yucatan Peninsula. In addition to the geological aspects of the fieldwork experience, the trip to Mexico exposed the teachers to a social environment outside of their community where they interacted with a diverse group of scientists from the Universidad National Autonoma de Mexico (UNAM), Centro de Investigacion Cientifica de Yucatan (CICY) and Centro Nacional de Desastres (CENAPRED). A key part of this project was the encounter between American and Mexican teachers that included a day of presentations, panel discussion and some class-room activities. Direct interaction between the cooperating teachers and the American and Mexican geoscientists provided actual scientific research experiences to educate and to help dispel misconceptions the teachers themselves may have had about who geoscientists really are and what they do. Teachers of the 2006 group produced educational materials from their field experiences and presented these materials at professional conferences. We measured the efficacy of these activities quantitatively via pre- and post-tests assessing confidence levels, preconceptions and biases, NIU staff observations of participants in their home institutions, and evaluations of participants' field books and pedagogical materials. We present these data here and identify specific activities that are both effective and efficient in changing teacher behaviours and attitudes enabling them to better connect with their Hispanic students in their Geoscience classrooms. Post experience activities of the 2008 group will build on these results.

This study was conducted before and after harvesting of wheat and maize in a typical agricultural landscape of the North China Plain. We investigated the diversity of two important natural enemy groups, carabids and spiders, using pitfall traps at crop field margin with different vegetation structures and their neighboring crop field. Throughout the comparison of the spatial and temporal distribution of the diversity of carabids and spiders in field margin and neighboring field, and the investigation of the relationship between arthropod communities and vegetation structure, this study aimed to understand the role of semi-natural field margin in biodiversity conservation of different natural enemy taxa. Results showed that the abundance of spiders was significantly higher in field margin than in neighboring fields over the entire period. No significant difference of the diversity of carabids in field margin and crop field was observed, but the community composition was different. Number of spider families increased in field margin but deceased in crop field after harvesting, indicating a migration activity between field and field margin. Vegetation structure in the field margin had different association with carabids than with spiders, with diversity of dominant carabid species positively associated with herb coverage and negatively with wood coverage, while the diversity of spider family Linyphiidae was positively associated with herb coverage only. Semi-natural habitat benefited the conservation of the diversity of arthropod natural enemies in crop field via promoting their dispersal to crop field, while such impacts differed from different vegetation structures and varied from target beneficial natural enemy communities. Future studies should focus on in-depth understanding of the food and habitat source requirement of different natural enemy taxa, and hence to design suitable semi-natural habitats to maintain a high diversity of natural enemy communities.

Remote photonic metrology in the conservation of cultural heritage

2013-05-01

Photonic technologies play a leading innovative role of research in the fields of Cultural Heritage (CH) conservation, preservation and digitisation. In particular photonic technologies have introduced a new indispensable era of research in the conservation of cultural artefacts expanding from decorative objects, paintings, sculptures, monuments to archaeological sites and including fields of application as diverse as materials characterisation to restoration practices and from defect topography to 3d artwork reconstruction. Thus the last two decades photonic technologies have emerged as unique answer or most competitive alternative into many long-term standing disputes in conservation and restoration of Cultural Heritage. Despite the impressive advances on the state-of-the-art ranging from custom-made system development to new methods and practises, photonic research and technological developments remain incoherently scattered and fragmented with a significant amount of duplication of work and misuse of resources. In this context, further progress should aim to capitalise on the so far achieved milestones in any of the diverse applications flourished in the field of CH. Embedding of experimental facilities and conclusions seems the only way to secure the progress beyond the existing state of the art and its false use. The solution to this embedment seems possible through the new computing environments. Cloud computing environment and remote laboratory access hold the missing research objective to bring the leading research together and integrate the achievements. The cloud environment would allow experts from museums, galleries, historical sites, art historians, conservators, scientists and technologists, conservation and technical laboratories and SMEs to interact their research, communicate their achievements and share data and resources. The main instrument of this integration is the creation of a common research platform termed here Virtual Laboratory allowing not only remote research, inspection and evaluation, but also providing the results to the members and the public with instant and simultaneous access to necessary information, knowledge and technologies. In this paper it is presented the concept and first results confirming the potential of implementing metrology techniques as remote digital laboratory facilities in artwork structural assessment. The method paves the way of the general objective to introduce remote photonic technologies in the sensitive field of Cultural Heritage.

Attracting and Maintaining Demographic Diversity in Energy: Lessons from Petroleum Engineering.

Diversity is important for any organization, its development and growth. However, frequently we observe that, if left to their own devices, many social and professional communities become self-selective, less susceptible to change, and, thus, less diverse. For example, this phenomenon can be readily observed in the academia when a professor forms a research group that is mostly comprised of people from certain origin or personal qualities. While on an individual level, this situation can be quite convenient and even beneficial, on the large scale the lack of diversity creates severe distortions and discourages many talented individuals from joining the group, organization, or industry in general. Diversity that includes ethnic, age, and gender aspects is a serious concern in overall energy industry and academia. One of the most prominent field impacted by diversity problems is petroleum engineering which can be used as a learning opportunity for other branches of energy industry. Using petroleum engineering community, we can understand what processes have led it to become self-selective, what measures have been applied to changes the situation and introduce more diversity.

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.

Narrative research in psychotherapy: a critical review.

PubMed

Avdi, Evrinomy; Georgaca, Eugenie

2007-09-01

This paper is a review of studies which utilise the notion of narrative to analyse psychotherapy. Its purpose is to systematically present this diverse field of research, to highlight common themes and divergences between different strands and to further the development and integration of narrative research in psychotherapy. The paper reviews studies which employ an applied textual analysis of narratives produced in the context of psychotherapy. Criteria for inclusion of studies are, firstly, the analysis of therapeutic and therapy-related texts and, secondly, the adoption of a narrative psychological perspective. The studies were examined on the basis of the notion of narrative they employ and the aspects of client narratives they focus on, and were grouped accordingly in the review. The majority of the studies reviewed assume a constructivist approach to narrative, adopt a representational view of language, focus primarily on client micro-narratives and relate to cognitive-constructivist and process-experiential psychotherapeutic approaches. A smaller group of studies assume a social constructionist approach to narrative and a functional view of language, focus on micro-narratives, highlight the interactional and wider social aspects of narrative and relate to postmodern trends in psychotherapy. The range of conceptualisations of narrative in the studies reviewed, from a representational psychological view to a constructionist social view, reflects tensions within narrative psychology itself. Moreover, two trends can be discerned in the field reviewed, narrative analysis of therapy, which draws from narrative theory and utilises the analytic approaches of narrative research to study psychotherapy, and analyses of narrative in therapy, which study client narratives using non-narrative qualitative methods. Finally, the paper highlights the need for integration of this diverse field of research and urges for the development of narrative studies of psychotherapy which employ a broader social understanding of narrative production and transformation.

Managing biological diversity

USGS Publications Warehouse

Samson, Fred B.; Knopf, Fritz L.

1993-01-01

Biological diversity is the variety of life and accompanying ecological processes (Off. Technol. Assess. 1987, Wilcove and Samson 1987, Keystone 1991). Conservation of biological diversity is a major environmental issue (Wilson 1988, Counc. Environ. Quality 1991). The health and future of the earth's ecological systems (Lubchenco et al. 1991), global climate change (Botkin 1990), and an ever-increasing rate in loss of species, communities, and ecological systems (Myers 1990) are among issues drawing biological diversity to the mainstream of conservation worldwide (Int. Union Conserv. Nat. and Nat. Resour. [IUCN] et al. 1991). The legal mandate for conserving biological diversity is now in place (Carlson 1988, Doremus 1991). More than 19 federal laws govern the use of biological resources in the United States (Rein 1991). The proposed National Biological Diversity Conservation and Environmental Research Act (H.R. 585 and S.58) notes the need for a national biological diversity policy, would create a national center for biological diversity research, and recommends a federal interagency strategy for ecosystem conservation. There are, however, hard choices ahead for the conservation of biological diversity, and biologists are grappling with how to set priorities in research and management (Roberts 1988). We sense disillusion among field biologists and managers relative to how to operationally approach the seemingly overwhelming charge of conserving biological diversity. Biologists also need to respond to critics like Hunt (1991) who suggest a tree farm has more biological diversity than an equal area of old-growth forest. At present, science has played only a minor role in the conservation of biological diversity (Weston 1992) with no unified approach available to evaluate strategies and programs that address the quality and quantity of biological diversity (Murphy 1990, Erwin 1992). Although actions to conserve biological diversity need to be clearly defined by viewing issues across biological, spatial, and temporal scales (Knopf and Smith 1992), natural resource managers find much conflicting information in the literature on strategies and programs for the conservation of biological diversity (Ehrlich 1992). Moreover, recommendations provided in much of the published information available for planning or decisions not only can be debated but may prove counterproductive if implemented. Current operational efforts beg for clearer focus on fundamental concepts central to daily decisions that impact native biological diversity. Recognizing that many biologists would provide different council and at the risk of oversimplification, we offer the following 4 topical issues as fundamental guidance to wise conservation action. These recommendations are based on our collective experiences working within conservation agencies since our original, collaborative essay (Samson and Knopf 1982). They are offered as initial, rather than authoritative, steps to better align research and management decisions with what we perceive as the critical issues in conserving biological diversity at the landscape and ecosystem levels of resolution.

A Conceptual Model for the Translation of Bioethics Research and Scholarship.

While the bioethics literature demonstrates that the field has spent substantial time and thought over the last four decades on the goals, methods, and desired outcomes for service and training in bioethics, there has been less progress defining the nature and goals of bioethics research and scholarship. This gap makes it difficult both to describe the breadth and depth of these areas of bioethics and, importantly, to gauge their success. However, the gap also presents us with an opportunity to define this scope of work for ourselves and to help shape the broader conversation about the impact of academic research. Because of growing constraints on academic funding, researchers and scholars in many fields are being asked to demonstrate and also forecast the value and impact of their work. To do that, and also to satisfy ourselves that our work has meaningful effect, we must understand how our work can motivate change and how that change can be meaningfully measured. In a field as diverse as bioethics, the pathways to and metrics of change will likewise be diverse. It is therefore critical that any assessment of the impact of bioethics research and scholarship be informed by an understanding of the nature of the work, its goals, and how those goals can and ought to be furthered. In this paper, we propose a conceptual model that connects individual bioethics projects to the broader goals of scholarship, describing the translation of research and scholarly output into changes in thinking, practice, and policy. One of the key implications of the model is that impact in bioethics is generally the result of a collection of projects rather than of any single piece of research or scholarship. Our goal is to lay the groundwork for a thoroughgoing conversation about bioethics research and scholarship that will advance and shape the important conversation about their impact. © 2016 The Hastings Center.

Diversity of cultivable β-glycosidase-producing micro-organisms isolated from the soil of a ginseng field and their ginsenosides-hydrolysing activity.

This research aimed to explore the diversity of cultivable β-glycosidase-producing micro-organisms in ginseng field soil. Fifty-three strains showing β-glucosidase activity were isolated from a ginseng field, using a newly designed Esculin-R2A agar. All the isolated strains belonged to the genus Agrobacterium, Arthrobacter, Burkholderia, Dyella, Edaphobacter, Luteibacter, Mucilaginibacter, Paenibacillus, Phenylobacterium, Pseudomonas, Sphingomonas and Streptomyces. The main β-glucosidase-producing micro-organisms in the ginseng field soil were Sphingomonas, Burkholderia, Luteibacter and Streptomyces, while concentrations of Agrobacterium, Arthrobacter, Paenibacillus and Pseudomonas were relatively low. Of these micro-organisms, the strain GS 09 could hydrolyse major ginsenosides Rb1, Rb2 and Rc to the active metabolite compound K. The strain GS 09 belonged to the genus Sphingomonas, and its 16S rRNA gene sequence showed 100% similarities with that of Sphingomonas asaccharolytica. This is the first study to provide information of cultivable β-glycosidase-producing micro-organisms in ginseng field soil. The strain GS 09 has potential to be applied on the preparation for minor ginsenoside C-K in pharmaceutical industry. © 2013 The Society for Applied Microbiology.

Respect for cultural diversity in bioethics is an ethical imperative.

PubMed

Chattopadhyay, Subrata; De Vries, Raymond

2013-11-01

The field of bioethics continues to struggle with the problem of cultural diversity: can universal principles guide ethical decision making, regardless of the culture in which those decisions take place? Or should bioethical principles be derived from the moral traditions of local cultures? Ten Have and Gordijn (Medicine, Health Care and Philosophy 14:1-3, 2011) and Bracanovic (Medicine, Health Care and Philosophy 14:229-236, 2011) defend the universalist position, arguing that respect for cultural diversity in matters ethical will lead to a dangerous cultural relativity where vulnerable patients and research subjects will be harmed. We challenge the premises of moral universalism, showing how this approach imports and imposes moral notions of Western society and leads to harm in non-western cultures.

This new field of inclusive education: beginning a dialogue on conceptual foundations.

Danforth, Scot; Naraian, Srikala

2015-02-01

Numerous scholars have suggested that the standard knowledge base of the field of special education is not a suitable intellectual foundation for the development of research, policy, and practice in the field of inclusive education. Still, we have yet to have a dialogue on what conceptual foundations may be most generative for the growth and development of the field of inclusive education. This article imagines and initiates such a new dialogue among educational researchers and teacher educators about the intellectual resources that can best support inclusive educators everywhere. As inclusive education gets increasingly taken up within international policy discourses, it may be imperative to explore and identify theories and ideas that can be responsive to diverse and hugely unequal contexts of schooling. This article forwards an initial collection of intellectual resources for an inclusive education that can accommodate such complex schooling conditions and invites rich scholarly exchange on this issue.

New Initiatives for a Successful Diversity Program at the University of New Orleans

NASA Astrophysics Data System (ADS)

Serpa, L.; Hall, F.

2002-12-01

The Geoscience Program at the University of New Orleans has been actively working to increase diversity in the Geosciences since 1974 when Dr. Louis Fernandez (now at Cal State San Bernardino) initiated a summer field trip for local minority high school juniors and seniors. That early effort was funded with a grant from the National Science Foundation. After the NSF support ended, the department and local Petroleum companies maintained the program continuously to the present. The summer field trip has been a major source of minority geoscientists nationally and our minority enrollment has grown rapidly during the past approximately 5 years primarily as a result of significant additional scholarship support from industry. Based on our preliminary success, we decided to make a major effort to expand our program beyond the basic field trip and scholarships. In particular, with a grant from the National Science Foundation Geoscience Diversity program beginning this past year, we have 1) initiated a new summer field program for high school freshmen and sophomores that focus on our local environment, 2) created a summer field trip for K-12 science teachers, 3) developed a new program of independent research for our undergraduate students and 4) brought in our first two visiting professors. The new summer program involved 10 students in a 2-1/2 week series of classes, field trips and camping activities. In addition to studying the environment, students produced a movie about their experiences and a website. We anticipate a larger group of students in next year's program and that several of this past summer's participants will apply to go on our field trip for Juniors and Seniors when they are eligible. The first summer field trip for teachers focused on the area around the Teton Mountains and Yellowstone National park in Wyoming and Idaho. We devoted considerable time to learning basic geologic principles and collecting rock and fossil samples, outside of the national parks, for their classrooms. The teachers prepared material on our field trip stops and we videotaped their presentations at the outcrops for future use in the classroom. Seven undergraduate students conducted independent research as part of our new program. One participated in a REU project in Rhode Island and the other six conducted a variety of independent projects at UNO. Two of these projects have produced abstracts for national meetings and others are anticipated. Finally, we have supported two visiting faculty to provide role models and classes relevant to our minority students. It is too early to assess the full success of most of these new initiatives but the independent research has clearly given our students an improved attitude about themselves and what they want to do with their future.

History, applications, and challenges of immune repertoire research.

PubMed

Liu, Xiao; Wu, Jinghua

2018-02-27

The diversity of T and B cells in terms of their receptor sequences is huge in the vertebrate's immune system and provides broad protection against the vast diversity of pathogens. Immune repertoire is defined as the sum of T cell receptors and B cell receptors (also named immunoglobulin) that makes the organism's adaptive immune system. Before the emergence of high-throughput sequencing, the studies on immune repertoire were limited by the underdeveloped methodologies, since it was impossible to capture the whole picture by the low-throughput tools. The massive paralleled sequencing technology suits perfectly the researches on immune repertoire. In this article, we review the history of immune repertoire studies, in terms of technologies and research applications. Particularly, we discuss several aspects of challenges in this field and highlight the efforts to develop potential solutions, in the era of high-throughput sequencing of the immune repertoire.

Antimicrobial peptides are among the most ancient effectors of host defense. Intersecting lines of research demonstrate that life forms as diverse as plants, insects, and vertebrates employ antimicrobial peptides to kill or neutralize a wide variety of microbial species. Defensins, of which there are three structural sub-families, constitute a major category of host defense peptides in vertebrates. Presented here is a brief history of the emergence of the defensin field with an emphasis on the role of these peptides in mammalian innate immunity.

Mentoring for Inclusion: The Impact of Mentoring on Undergraduate Researchers in the Sciences

Haeger, Heather; Fresquez, Carla

2016-01-01

Increasing inclusion of underrepresented minority and first-generation students in mentored research experiences both increases diversity in the life sciences research community and prepares students for successful careers in these fields. However, analyses of the impact of mentoring approaches on specific student gains are limited. This study addresses the impact of mentoring strategies within research experiences on broadening access to the life sciences by examining both how these experiences impacted student success and how the quality of mentorship affected the development of research and academic skills for a diverse population of students at a public, minority-serving institution. Institutional data on student grades and graduation rates (n = 348) along with postresearch experience surveys (n = 138) found that students mentored in research had significantly higher cumulative grade point averages and similar graduation rates as a matched set of peers. Examination of the relationships between student-reported gains and mentoring strategies demonstrated that socioemotional and culturally relevant mentoring impacted student development during mentored research experiences. Additionally, extended engagement in research yielded significantly higher development of research-related skills and level of independence in research. Recommendations are provided for using mentoring to support traditionally underrepresented students in the sciences. PMID:27543635

The scholars comprising journal editorial boards play a critical role in defining the trajectory of knowledge in their field. Nevertheless, studies of editorial board composition remain rare, especially those focusing on journals publishing research in the increasingly globalized fields of science, technology, engineering, and math (STEM). Using metrics for quantifying the diversity of ecological communities, we quantified international representation on the 1985-2014 editorial boards of 24 environmental biology journals. Over the course of 3 decades, there were 3,827 unique scientists based in 70 countries who served as editors. The size of the editorial community increased over time-the number of editors serving in 2014 was 4-fold greater than in 1985-as did the number of countries in which editors were based. Nevertheless, editors based outside the "Global North" (the group of economically developed countries with high per capita gross domestic product [GDP] that collectively concentrate most global wealth) were extremely rare. Furthermore, 67.18% of all editors were based in either the United States or the United Kingdom. Consequently, geographic diversity-already low in 1985-remained unchanged through 2014. We argue that this limited geographic diversity can detrimentally affect the creativity of scholarship published in journals, the progress and direction of research, the composition of the STEM workforce, and the development of science in Latin America, Africa, the Middle East, and much of Asia (i.e., the "Global South").

The Astrobiology Primer has been created as a reference tool for those who are interested in the interdisciplinary field of astrobiology. The field incorporates many diverse research endeavors, but it is our hope that this slim volume will present the reader with all he or she needs to know to become involved and to understand, at least at a fundamental level, the state of the art. Each section includes a brief overview of a topic and a short list of readable and important literature for those interested in deeper knowledge. Because of the great diversity of material, each section was written by a different author with a different expertise. Contributors, authors, and editors are listed at the beginning, along with a list of those chapters and sections for which they were responsible. We are deeply indebted to the NASA Astrobiology Institute (NAI), in particular to Estelle Dodson, David Morrison, Ed Goolish, Krisstina Wilmoth, and Rose Grymes for their continued enthusiasm and support. The Primer came about in large part because of NAI support for graduate student research, collaboration, and inclusion as well as direct funding. We have entitled the Primer version 1 in hope that it will be only the first in a series, whose future volumes will be produced every 3-5 years. This way we can insure that the Primer keeps up with the current state of research. We hope that it will be a great resource for anyone trying to stay abreast of an ever-changing field.

The historical underpinnings in the field of gerontology rest on the contributions of scholars across a myriad of racial and ethnic backgrounds. With the increasing diversity of the adult population, there is a need to increase the number of researchers who study older adults from diverse racial and ethnic populations in general and Black elderly people in particular. Furthermore, it is important to document the participation of Black older adults in our earliest and continuing research efforts. Understanding the historical context and the foundational influence of Black scholars in this field is critical. To realize its humble beginnings, one must become aware of the contributions by Black scholars who have a vested interest in the aging process. With universal similarities and unique differences among older adults, there is a need to acknowledge the past and current scholarship of those who study the aging processes of Blacks while marveling over the future possibilities. The purpose of this review is to elucidate the legacy and current contributions, philosophies, and research of Black scholars in the field of gerontology. In addition, exploration of the theoretical and conceptual frameworks used to establish national and organizational initiatives is reviewed. The impetus in initiating and continuing this work requires a “knowledge of our roots” while moving into the future. It is important to learn the history and significance of Black scholars in gerontology, the contributions of older Blacks, and appreciate the resiliency and marveled life course of this unique population.

Disability research in counseling psychology journals: a 20-year content analysis.

PubMed

Foley-Nicpon, Megan; Lee, Sharon

2012-07-01

We conducted an exploratory content analysis of disability research in 5 major counseling psychology journals between 1990 and 2010. The goal was to review the counseling psychology literature to better understand the prevalence of disability research, identify research methods most often conducted, and elucidate the types of concerns most studied. We searched 5 journals (Journal of Counseling & Development, Journal of Counseling Psychology, The Counseling Psychologist, Journal of Multicultural Counseling and Development, and Cultural Diversity and Ethnic Minority Psychology) using keywords derived from disability terms defined by the Individuals With Disabilities Education Improvement Act of 2004 (IDEA). Articles were categorized by methodology and disability category examined. We found that disability research continues to comprise an extremely small amount (from less than 1% to 2.7%) of the counseling psychology literature, with the frequency of articles plateauing in recent years. The research design of articles published has changed, with an increased number of empirical articles and a decrease in literature reviews. We conclude by calling for increased empirical investigation of disability among journals specific to counseling psychology to recognize disability as an important aspect of diversity within the field.

Avian Species and Functional Diversity in Agricultural Landscapes: Does Landscape Heterogeneity Matter?

PubMed Central

2017-01-01

While the positive relationship between avian diversity and habitat heterogeneity is widely accepted, it is primarily based on observed species richness without accounting for imperfect detection. Other facets of diversity such as functional diversity are also rarely explored. We investigated the avian diversity-landscape heterogeneity relationship in agricultural landscapes by considering two aspects of diversity: taxonomic diversity (species richness) estimated from a multi-species dynamic occupancy model, and functional diversity (functional evenness [FEve] and divergence [FDiv]) based on traits of occurring species. We also assessed how agricultural lands enrolled in a conservation program managed on behalf of declining early successional bird species (hereafter CP38 fields, an agri-environment scheme) influenced avian diversity. We analyzed breeding bird data collected at CP38 fields in Mississippi, USA, during 2010–2012, and two principal components of environmental variables: a gradient of heterogeneity (Shannon’s landscape diversity index) and of the amount of CP38 fields (percent cover of CP38 fields; CP38). FEve did not show significant responses to environmental variables, whereas FDiv responded positively to heterogeneity and negatively to CP38. However, most FDiv values did not significantly differ from random expectations along an environmental gradient. When there was a significant difference, FDiv was lower than that expected. Unlike functional diversity, species richness showed a clear pattern. Species richness increased with increasing landscape heterogeneity but decreased with increasing amounts of CP38 fields. Only one species responded negatively to heterogeneity and positively to CP38. Our results suggest that the relationships between avian diversity and landscape heterogeneity may vary depending on the aspect of diversity considered: strong positive effects of heterogeneity on taxonomic diversity, but weakly positive or non-significant effects on functional diversity. Our results also indicate that effectiveness of CP38 in conserving avian diversity, particularly, taxonomic diversity, could be limited without the consideration of landscape heterogeneity.

Introduction: For small communities in diverse fields such as astrobiology, publishing and sharing data can be a difficult challenge. While large, homogenous fields often have repositories and existing data standards, small groups of independent researchers have few options for publishing standards and data that can be utilized within their community. In conjunction with teams at NASA Ames and the University of Arizona, the Open Data Repository's (ODR) Data Publisher has been conducting ongoing pilots to assess the needs of diverse research groups and to develop software to allow them to publish and share their data collaboratively. Objectives: The ODR's Data Publisher aims to provide an easy-to-use and implement software tool that will allow researchers to create and publish database templates and related data. The end product will facilitate both human-readable interfaces (web-based with embedded images, files, and charts) and machine-readable interfaces utilizing semantic standards. Characteristics: The Data Publisher software runs on the standard LAMP (Linux, Apache, MySQL, PHP) stack to provide the widest server base available. The software is based on Symfony (www.symfony.com) which provides a robust framework for creating extensible, object-oriented software in PHP. The software interface consists of a template designer where individual or master database templates can be created. A master database template can be shared by many researchers to provide a common metadata standard that will set a compatibility standard for all derivative databases. Individual researchers can then extend their instance of the template with custom fields, file storage, or visualizations that may be unique to their studies. This allows groups to create compatible databases for data discovery and sharing purposes while still providing the flexibility needed to meet the needs of scientists in rapidly evolving areas of research. Research: As part of this effort, a number of ongoing pilot and test projects are currently in progress. The Astrobiology Habitable Environments Database Working Group is developing a shared database standard using the ODR's Data Publisher and has a number of example databases where astrobiology data are shared. Soon these databases will be integrated via the template-based standard. Work with this group helps determine what data researchers in these diverse fields need to share and archive. Additionally, this pilot helps determine what standards are viable for sharing these types of data from internally developed standards to existing open standards such as the Dublin Core (http://dublincore.org) and Darwin Core (http://rs.twdg.org) metadata standards. Further studies are ongoing with the University of Arizona Department of Geosciences where a number of mineralogy databases are being constructed within the ODR Data Publisher system. Conclusions: Through the ongoing pilots and discussions with individual researchers and small research teams, a definition of the tools desired by these groups is coming into focus. As the software development moves forward, the goal is to meet the publication and collaboration needs of these scientists in an unobtrusive and functional way.

Setting research priorities by applying the combined approach matrix.

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.

Orientation of colonized sand flies Phlebotomus papatasi, P. duboscqi, and Lutzomyia longipalpis (Diptera: Psychodidae) to diverse honeys using a 3-chamber in-line olfactometer.

A 3-chamber in-line olfactometer designed for use with sand flies is described and tested as a high-throughput method to screen honeys for attractiveness to Phlebotomus papatasi (four geographic isolates), P. duboscqi (two geographic isolates), and Lutzomyia longipalpis maintained in colonies at the Walter Reed Army Institute of Research. A diversity of unifloral honey odors were evaluated as a proxy for the natural floral odors that sand flies may use in orientation to floral sugar sources in the field. In the 3-chamber in-line olfactometer, the choice modules come directly off both sides of the release area instead of angling away as in the Y-tube olfactometer. Of the 25 honeys tested, five had a significant attraction for one or more of the sand fly isolates tested. This olfactometer and high-throughput method has utility for evaluating a diversity of natural materials with unknown complex odor blends that can then be down-selected for further evaluation in wind tunnels and/or field scenarios. © 2014 The Society for Vector Ecology.

The field of urban stream ecology has evolved rapidly in the last 3 decades, and it now includes natural scientists from numerous disciplines working with social scientists, landscape planners and designers, and land and water managers to address complex, socioecological problems that have manifested in urban landscapes. Over the last decade, stream ecologists have met 3 times at the Symposium on Urbanization and Stream Ecology (SUSE) to discuss current research, identify knowledge gaps, and promote future research collaborations. The papers in this special series on urbanization and stream ecology include both primary research studies and conceptual synthesis papers spurred from discussions at SUSE in May 2014. The themes of the meeting are reflected in the papers in this series emphasizing global differences in mechanisms and responses of stream ecosystems to urbanization and management solutions in diverse urban streams. Our hope is that this series will encourage continued interdisciplinary and collaborative research to increase the global understanding of urban stream ecology toward stream protection and restoration in urban landscapes.

A Case Study on Science Teacher Leadership to Address Diversity and Equity Through Professional Development

NASA Astrophysics Data System (ADS)

Doraiswamy, Nithya

This qualitative case study focused on the multifaceted issue of exploring science teacher leaders understanding and addressing of issues of diversity and equity with peers through professional development. The purpose of the study was to highlight the opportunities and barriers to the addressing of issues of diversity and equity through the work of a community of teachers leaders in science professional development. To frame this study, the researcher drew from the interdisciplinary field of multicultural education, transformative learning, and teacher leadership. In drawing out the connections from these vast bodies of literature, the study speaks to the need of both, creating teacher leaders in science education who are capable of meeting the twin demands of excellence and equity, and also attending to the challenges in the professional learning continuums of teachers leaders and their peers towards addressing issues of diversity and equity in science education.

Passive Polarimetric Information Processing for Target Classification

Sadjadi, Firooz; Sadjadi, Farzad

Polarimetric sensing is an area of active research in a variety of applications. In particular, the use of polarization diversity has been shown to improve performance in automatic target detection and recognition. Within the diverse scope of polarimetric sensing, the field of passive polarimetric sensing is of particular interest. This chapter presents several new methods for gathering in formation using such passive techniques. One method extracts three-dimensional (3D) information and surface properties using one or more sensors. Another method extracts scene-specific algebraic expressions that remain unchanged under polariza tion transformations (such as along the transmission path to the sensor).

Progress Towards an Interdisciplinary Science of Plant Phenology: Building Predictions Across Space, Time and Species Diversity

Climate change has brought renewed interest in the study of plant phenology - the timing of life history events. Data on shifting phenologies with warming have accumulated rapidly, yet research has been comparatively slow to explain the diversity of phenological responses observed across latitudes, growing seasons and species. Here, we outline recent efforts to synthesize perspectives on plant phenology across the fields of ecology, climate science and evolution. We highlight three major axes that vary among these disciplines: relative focus on abiotic versus biotic drivers of phenology, on plastic versus genetic drivers of intraspecific variation, and on cross-species versus autecological approaches. Recent interdisciplinary efforts, building on data covering diverse species and climate space, have found a greater role of temperature in controlling phenology at higher latitudes and for early-flowering species in temperate systems. These efforts have also made progress in understanding the tremendous diversity of responses across species by incorporating evolutionary relatedness, and linking phenological flexibility to invasions and plant performance. Future research with a focus on data collection in areas outside the temperate mid-latitudes and across species' ranges, alongside better integration of how risk and investment shape plant phenology, offers promise for further progress.

Based on a new model of productivity in age diverse tams, findings from a six-year research program are reported in which data from more than 745 natural teams with 8,848 employees in three different fields (car production, administrative work, financial services) were collected. Moreover, central assumptions of this model were tested with a representative survey of the German workforce (N = 2,000). Results support both significant advantages and disadvantages for age-mixed teams. Based on the findings, the following preconditions for the effectiveness of age diverse teams are identified: high task complexity, low salience and high appreciation of age diversity, a positive team climate, low age-discrimination, ergonomic design of work places, and the use of age differentiated leadership. Based on these insights, we developed a new training for supervisors, which addresses the aforementioned aspects and seeks to improve team performance and health of team members. It was found that the training reduces age stereotypes, team conflicts and enhances innovation. Thus, we can conclude that effective interventions for a successful integration of elderly employees in work groups are available and that combinations of measures that address ergonomic design issues, team composition and leadership are to be strongly recommended for practice.

Multicontext Diversity: The critical dimension of diversity that can attract students and help them thrive

NASA Astrophysics Data System (ADS)

Weissmann, G. S.; Ibarra, R.; Howland-Davis, M.

2017-12-01

Diversity programs on college campuses have expanded over the past several decades, bringing a broad range of students to academia; however, these programs have not resulted in diversification of faculty or PhD students. Current diversity programs generally focus on two dimensions of diversity: (1) structural diversity, which aims to bring in students from underrepresented groups to college campuses through scholarships, admissions policies, and targeted marketing; and (2) multicultural diversity, which uses programs designed to give students from underrepresented groups homes on campus and programs designed to study cultural aspects of different groups. Though these programs are important, something else must be controlling the lack of minority participation in STEM at advanced levels. We posit that a third dimension of diversity, context diversity, is lacking in university education, especially in STEM fields, and without accessing this form of diversity, programs will never benefit from the broader diversity of society. Context diversity results through application of Multicontext theory, which both explains and predicts the inclusion of exclusion of people within an institutional culture. It describes how different cultures approach understanding the world around them. This "cultural ways of knowing and doing" has been described using a binary system, consisting of "Low Context" and "High Context" cultures. Ibarra (2001) described how a spectrum exists between these end members, and thus individuals brought up in different cultures will understand the world from somewhere along this context diversity spectrum. Academic culture tends to fall on the low context side of the spectrum. Thus, students (and faculty) who come from cultures that tend toward the high context side of the spectrum often feel excluded from the academic setting, especially in STEM fields which tend to be strongly low context in nature. A high percentage of students from underrepresented groups and women tend to fall on toward the high context side of the spectrum, thus this disproportionately affects women and minorities. Multicontextuality can be readily applied in classroom and research settings, thus leading to helping all students thrive in the academic setting.

Access to study populations is a major concern for drug use and treatment researchers. Spaces related to drug use and treatment have varying levels of researcher accessibility based on several issues, including legality, public versus private settings, and insider/outsider status. Ethnographic research methods are indispensable for gaining and maintaining access to hidden or "hard-to-reach" populations. Here, we discuss our long-term ethnographic research on drug abuse recovery houses created by and for Latino migrants and immigrants in Northern California. We take our field work experiences as a case study to examine the problem of researcher access and how ethnographic strategies can be successfully applied to address it, focusing especially on issues of entrée, building rapport, and navigating field-specific challenges related to legality, public/private settings, and insider/outsider status. We conclude that continued funding support for ethnography is essential for promoting health disparities research focused on diverse populations in recovery from substance use disorders.

Fostering Diversity in the Earth and Space Sciences: The Role of AGU

NASA Astrophysics Data System (ADS)

Snow, J. T.; Johnson, R. M.; Hall, F. R.

2002-12-01

In May 2002, AGU's Committee on Education and Human Resources (CEHR) approved a new Diversity Plan, developed in collaboration with the CEHR Subcommittee on Diversity. Efforts to develop a diversity plan for AGU were motivated by the recognition that the present Earth and space science community poorly represents the true diversity of our society. Failure to recruit a diverse scientific workforce in an era of rapidly shifting demographics could have severe impact on the health of our profession. The traditional base of Earth and space scientists in the US (white males) has been shrinking during the past two decades, but women, racial and ethnic minorities, and persons with disabilities are not compensating for this loss. The potential ramifications of this situation - for investigators seeking to fill classes and recruit graduate students, for institutions looking to replace faculty and researchers, and for the larger community seeking continued public support of research funding - could be crippling. AGU's new Diversity Plan proposes a long-term strategy for addressing the lack of diversity in the Earth and space sciences with the ultimate vision of reflecting diversity in all of AGU's activities and programs. Four key goals have been identified: 1) Educate and involve the AGU membership in diversity issues; 2) Enhance and foster the participation of Earth and space scientists, educators and students from underrepresented groups in AGU activities; 3) Increase the visibility of the Earth and space sciences and foster awareness of career opportunities in these fields for underrepresented populations; and 4) Promote changes in the academic culture that both remove barriers and disincentives for increasing diversity in the student and faculty populations and reward member faculty wishing to pursue these goals. A detailed implementation plan that utilizes all of AGU's resources is currently under development in CEHR. Supportive participation by AGU members and coordination between AGU's efforts and those of other scientific society working to improve diversity will be important components in achieving the goals of this plan.

Doctoral Programs Need Changes to Attract and Retain Underrepresented Groups

NASA Astrophysics Data System (ADS)

Bernard, R. E.; Mayfield, K. K.

2017-12-01

Geoscience is currently recognized as the least diverse of all STEM fields. While attention typically focuses on K-12 and undergraduate populations, the extreme lack of diversity among graduate students, and doctoral students in particular, should be examined and addressed. In 2016, members of underrepresented minority (URM) groups made up only 6% of those graduating with geoscience PhDs. In all STEM fields, only 48% of Hispanic/Latino and 38% of Black/African American doctoral studies had earned doctorates within 7 years, with 36% of members of these groups leaving the program entirely. Recent studies suggest that these high attrition rates can be attributed, in part, to a mismatch between motivations of URM members and PhD-granting institutions while students are pursuing scientific education and careers. Traditional STEM doctoral programs do not offer, facilitate, or incentivize substantial opportunities to integrate social justice issues, community involvement, and altruism—factors which have been found to be of more importance to these populations than to male members of well-represented groups. URM members are also less likely to be interested in purely academic research careers, so doctoral programs may be failing to attract (and failing to prepare) diverse populations by not offering experiences beyond typical research and TA duties. In this presentation, trends in motivation and persistence among URM students in STEM will be discussed, in addition to highlighting education and outreach activities that can be successfully incorporated for a more fulfilling, balanced, attractive, and preparatory education experience. Specific activities undertaken and recommended by the presenter in her PhD experience include the following: a federal research internship, a state government policy internship, a formal partnership with a local K-12 teacher though a former NSF GK-12 program, a two-week education workshop aboard a scientific research drillship, and attending a research conference geared towards URM students (SACNAS). Suggestions and recommendations will be made for meaningful changes at the institutional, funding agency, societal and community levels.

Objective To examine the size and characteristics of the health services research (HSR) workforce; the job satisfaction, job security, and future plans reported by the workforce; and the future of the HSR workforce supply. Data Sources (1) AcademyHealth active and lapsed members since 2000 and annual research meeting presenters and interest group participants; (2) principal investigators of research projects listed in the HSRProj database; and (3) authors of articles published in two HSR journals. Study Design Data on investigators conducting HSR in selected venues were collected and compared in order to identify the percentage of the HSR workforce represented in the “core” versus related disciplines and to investigate the extent to which the “core” researchers publish, present, or participate in disciplinary venues. Principal Findings The field appears to have grown dramatically since 1995, from an estimated 5,000 health services researchers to an estimated 11,596 in 2007. This is a broad workforce characterized by various levels of involvement in the field. Some researchers self-identify with the field of HSR, while others are associated primarily with venues related to specific disciplines. Many researchers who identify with HSR also publish in venues related to multiple other disciplines. Conclusions The field may face future challenges related to demographic change, such as an aging workforce and an increased need for diversity. International collaboration appears common, and in the future the field may need to be defined internationally rather than nationally. At the same time, there are also many indications that HSR is a good field to work in. Health services researchers reported high levels of satisfaction with their profession and current employer, as well as little desire to change jobs and little concern about job security.

Gabriel, Doreen; Roschewitz, Indra; Tscharntke, Teja; Thies, Carsten

2006-10-01

Biodiversity studies that guide agricultural subsidy policy have generally compared farming systems at a single spatial scale: the field. However, diversity patterns vary across spatial scales. Here, we examined the effects of farming system (organic vs. conventional) and position in the field (edge vs. center) on plant species richness in wheat fields at three spatial scales. We quantified alpha-, beta-, and gamma-diversity at the microscale in 800 plots, at the mesoscale in 40 fields, and at the macroscale in three regions using the additive partitioning approach, and evaluated the relative contribution of beta-diversity at each spatial scale to total observed species richness. We found that alpha-, beta-, and gamma-diversity were higher in organic than conventional fields and higher at the field edge than in the field center at all spatial scales. In both farming systems, beta-diversity at the meso- and macroscale explained most of the overall species richness (up to 37% and 25%, respectively), indicating considerable differences in community composition among fields and regions due to environmental heterogeneity. The spatial scale at which beta-diversity contributed the most to overall species richness differed between rare and common species. Total richness of rare species (present in < or = 5% of total samples) was mainly explained by differences in community composition at the meso- and macroscale (up to 27% and 48%, respectively), but only in organic fields. Total richness of common species (present in > or = 25% of total samples) was explained by differences in community composition at the micro- and mesoscale (up to 29% and 47%, respectively), i.e., among plots and fields, independent of farming system. Our results show that organic farming made the greatest contribution to total species richness at the meso (among fields) and macro (among regions) scale due to environmental heterogeneity. Hence, agri-environment schemes should exploit this large-scale contribution of beta-diversity by tailoring schemes at regional scales to maximize dissimilarity between conservation areas using geographic information systems rather than focusing entirely at the classical local-field scale, which is the current practice.

The Health Services Researcher of 2020: A Summit to Assess the Field's Workforce Needs

2009-01-01

Objective To summarize the current state of the health services research (HSR) workforce and recommend ways to improve the field's ability to respond to future challenges facing the health system. Data Summaries of workgroup discussions and recommendations at a stakeholder meeting. Study Design In late 2007, 50 educators, students, employers, and funders of HSR participated in a meeting to discuss findings of three commissioned papers on the HSR workforce. The group undertook a consultative process to develop recommendations for the field. Principal Findings Stakeholders developed recommendations in five major areas focused on HSR workforce needs: (1) improving the size and composition of the field; (2) understanding the growth of HSR in the private sector; (3) improving the graduate training of health services researchers, especially at the master's level; (4) expanding postgraduate training and continuing education opportunities; and (5) increasing awareness of the value of HSR. Conclusions Specific recommendations in the five major areas emphasized developing partnerships between HSR organizations and other professional societies or health organizations, as well as ways to improve training for the future workforce. The need to develop a “client orientation” toward research by improving communication and dissemination skills was discussed, as was the importance of improving diversity in the field. PMID:20459583

"A mission-driven discipline": the growth of conservation biology.

PubMed

Meine, Curt; Soulé, Michael; Noss, Reed E

2006-06-01

Conservation biology emerged in the mid-1980s, drawing on established disciplines and integrating them in pursuit of a coherent goal: the protection and perpetuation of the Earth's biological diversity. Opportunistic in its borrowing and application of knowledge, conservation biology had its roots within the established biological sciences and resource management disciplines but has continually incorporated insights from the empirical experience of resource managers, from the social sciences and humanities, and from diverse cultural sources. The Society for Conservation Biology (SCB) has represented the field's core constituency, while expanding that constituency in keeping with the field's integrative spirit. Conservation Biology has served as SCB's flagship publication, promoting research, dialog, debate, and application of the field's essential concepts. Over the last 20 years the field, SCB, and the journal have evolved to meet changing conservation needs, to explore gaps in our knowledge base, to incorporate new information from related fields, to build professional capacity, and to provide expanded opportunities for international participation. In turn, the field, SCB, and journal have prompted change in related fields, organizations, and publications. In its dedication to advancing the scientific foundations of biodiversity conservation and placing that science at the service of society in a world whose variety, wildness, and beauty we care for conservation biology represents both a continuation and radical reconfiguration of the traditional relationship between science and conservation.

Survey of Academic Field Experiences (SAFE): Trainees Report Harassment and Assault

Clancy, Kathryn B. H.; Nelson, Robin G.; Rutherford, Julienne N.; Hinde, Katie

2014-01-01

Little is known about the climate of the scientific fieldwork setting as it relates to gendered experiences, sexual harassment, and sexual assault. We conducted an internet-based survey of field scientists (N = 666) to characterize these experiences. Codes of conduct and sexual harassment policies were not regularly encountered by respondents, while harassment and assault were commonly experienced by respondents during trainee career stages. Women trainees were the primary targets; their perpetrators were predominantly senior to them professionally within the research team. Male trainees were more often targeted by their peers at the research site. Few respondents were aware of mechanisms to report incidents; most who did report were unsatisfied with the outcome. These findings suggest that policies emphasizing safety, inclusivity, and collegiality have the potential to improve field experiences of a diversity of researchers, especially during early career stages. These include better awareness of mechanisms for direct and oblique reporting of harassment and assault and, the implementation of productive response mechanisms when such behaviors are reported. Principal investigators are particularly well positioned to influence workplace culture at their field sites. PMID:25028932

McMahon, Dominique S; Thorsteinsdóttir, Halla; Singer, Peter A; Daar, Abdallah S

2010-01-01

While China has become a significant contributor and prolific publisher in regenerative medicine, its role in the field is not well understood. We analyze how capacity in regenerative medicine was built in China to identify some of its main strengths and challenges. This case study of regenerative medicine in China is primarily based on interviews with experts in China, including researchers, policy makers, clinicians, representatives of firms and regulators. Our analysis shows that diverse groups are active in this field in China. Leading research groups are contributing extensively to international peer-reviewed journals. Strong governmental support and recruitment of highly trained Chinese scientists from abroad has made it possible for China to rapidly build up capacity in regenerative medicine. However, some hospitals in China are offering stem cell therapies with limited scientific evidence supporting their efficacy/safety, and international skepticism of medical research in China presents a challenge to the development of the field. China has been able to catapult itself into the forefront of regenerative medicine but needs to address current regulatory challenges in order to secure its position in this emerging field.

Cultural Diversity Training: The Necessity of Cultural Competence for Health Care Providers and in Nursing Practice.

Young, Susan; Guo, Kristina L

2016-01-01

The purpose of this article is to discuss the need to provide culturally sensitive care to the growing number of diverse health care consumers. A literature review of national standards and research on cultural competency was conducted and specifically focused on the field of nursing. This study supports the theory that cultural competence is learned over time and is a process of inner reflection and awareness. The domains of awareness, skill, and knowledge are essential competencies that must be gained by health care providers and especially for nurses. Although barriers to providing culturally sensitive care exist, gaining a better understanding of cultural competence is essential to developing realistic education and training techniques, which will lead to quality professional nursing practice for increasingly diverse populations.

Since 2001, faculty and graduate students in the Department of Geosciences at San Francisco State University (SFSU) have coordinated a program to encourage high school students from traditionally underrepresented groups to pursue the geosciences. The SF-ROCKS (Reaching Out to Communities and Kids with Science in San Francisco) program is a multifaceted NSF-funded program that includes curriculum enhancement, teacher in-service training, summer and academic year research experiences for high school students, and field excursions to national parks. Six faculty, five graduate students, and several undergraduate students work together to develop program activities. Working with 9th grade integrated science courses, the students are introduced to SF-ROCKS through lesson plans and activities that focus on the unique geologic environments that surround the schools. Each year a group of twelve to fifteen students is selected to participate in a summer and academic year research institute at the SFSU campus. In the four years of our program, twenty-seven ninth and tenth-grade students have participated in the summer and academic year research experiences. We have observed increased interest and skill development as the high school students work closely with university faculty and students. As SF-ROCKS continues to expand, we are exploring ways to partner with other diversity programs such as the long-standing University of New Orleans (UNO) Minority Geoscience summer field program. The UNO program is successful because it combines field exposure and mentoring with scholarship opportunities for students making it more likely they will study geosciences in college. SF-ROCKS is creating additional ways to further enhance the students' perspective of the geosciences through meaningful field and scientific research experiences by focusing on local and regional geologic environments and also on the geology of national parks.

Tissue Engineering in Animal Models for Urinary Diversion: A Systematic Review

2014-01-01

Tissue engineering and regenerative medicine (TERM) approaches may provide alternatives for gastrointestinal tissue in urinary diversion. To continue to clinically translatable studies, TERM alternatives need to be evaluated in (large) controlled and standardized animal studies. Here, we investigated all evidence for the efficacy of tissue engineered constructs in animal models for urinary diversion. Studies investigating this subject were identified through a systematic search of three different databases (PubMed, Embase and Web of Science). From each study, animal characteristics, study characteristics and experimental outcomes for meta-analyses were tabulated. Furthermore, the reporting of items vital for study replication was assessed. The retrieved studies (8 in total) showed extreme heterogeneity in study design, including animal models, biomaterials and type of urinary diversion. All studies were feasibility studies, indicating the novelty of this field. None of the studies included appropriate control groups, i.e. a comparison with the classical treatment using GI tissue. The meta-analysis showed a trend towards successful experimentation in larger animals although no specific animal species could be identified as the most suitable model. Larger animals appear to allow a better translation to the human situation, with respect to anatomy and surgical approaches. It was unclear whether the use of cells benefits the formation of a neo urinary conduit. The reporting of the methodology and data according to standardized guidelines was insufficient and should be improved to increase the value of such publications. In conclusion, animal models in the field of TERM for urinary diversion have probably been chosen for reasons other than their predictive value. Controlled and comparative long term animal studies, with adequate methodological reporting are needed to proceed to clinical translatable studies. This will aid in good quality research with the reduction in the use of animals and an increase in empirical evidence of biomedical research. PMID:24964011

Healthy Variability in Organizational Behavior: Empirical Evidence and New Steps for Future Research.

Navarro, José; Rueff-Lopes, Rita

2015-10-01

The healthy variability thesis suggests that healthy systems function in a complex manner over time. This thesis is well-established in fields like physiology. In the field of organizational behavior, however, this relation is only starting to be explored. The objective of this article is threefold: First, we aim to provide a comprehensive review of the healthy variability thesis including some of the most important findings across different fields, with a focus on evidences from organizational research in work motivation and performance. Second, we discuss an opposite pattern, unhealthy stability, i.e., the relationship between unhealthy behaviors and lower variability. Again, we provide evidence from diverse areas, from affective processes to disruptive organizational comportments like mobbing. Third, we provide a critical evaluation of current methodological trends and highlight what we believe to be the main factors that are stopping organizational research from advancing in the field. Theoretical, methodological and epistemological implications are discussed. To conclude, we draw a compilation of the lessons learned, which hopefully provide insights for prolific research avenues. Our main purpose is to raise awareness of the healthy variability thesis and to enthuse organizational researchers to consider it in order to advance existing knowledge, revisit old theories and create new ones.

Can disability studies and psychology join hands?

Olkin, Rhoda; Pledger, Constance

2003-04-01

Although the field of disabilities studies incorporates psychology within its interdisciplinary purview, it embodies a distinct perspective consonant with the new paradigm of disability. This perspective is contrasted with that of psychology, and the place of disability within psychology is examined. Although psychology has begun to embrace diversity, disability has remained marginalized. Four areas are presented in this article: (a) the foundational ideas of disability studies, (b) training in disability within psychology, (c) the paradigms of disability reflected in research on disability, and (d) future research directions.

The biodiversity of Madagascar is extraordinarily distinctive, diverse, and endangered. It is therefore urgent that steps be taken to document, describe, interpret, and protect this exceptional biota. As a collaborative group of field and laboratory biologists, we employ a suite of methodological and analytical tools to investigate the vertebrate portion of Madagascar's fauna. Given that species are the fundamental unit of evolution, where micro- and macroevolutionary forces converge to generate biological diversity, a thorough understanding of species distribution and abundance is critical for understanding the evolutionary, ecological, and biogeographic forces that have shaped Malagasy vertebrate diversity. We illustrate the means by which we apply Mayr's “three basic tasks” of the systematist [Mayr, E. (1942) Systematics and the Origin of Species from the Viewpoint of a Zoologist (Harvard Univ. Press, Cambridge, MA)] to identify, classify, and study the organisms that together constitute Madagascar's vertebrate community. Using field inventory methods, specimen-based studies, and morphological and molecular analyses, we formulate hypotheses of species identity that then serve as the foundation for subsequent studies of biology and history. Our experience, as well as that of other investigators, has shown that much of the vertebrate species diversity in Madagascar is “cryptic” for both biological and practical reasons. Beyond issues of cryptic biological diversity, the resolution of species identity in Madagascar has been hampered because of a lack of vouchered comparative material at the population level. Through our activities, we are attempting to remedy these limitations while simultaneously enhancing research capacity in Madagascar. PMID:15851666

Microbial rhodopsins are a diverse group of photoactive transmembrane proteins found in all three domains of life and in viruses. Today, microbial rhodopsin research is a flourishing research field in which new understandings of rhodopsin diversity, function and evolution are contributing to broader microbiological and molecular knowledge. Here, we describe MicRhoDE, a comprehensive, high-quality and freely accessible database that facilitates analysis of the diversity and evolution of microbial rhodopsins. Rhodopsin sequences isolated from a vast array of marine and terrestrial environments were manually collected and curated. To each rhodopsin sequence are associated related metadata, including predicted spectral tuning of the protein, putative activity and function, taxonomy for sequences that can be linked to a 16S rRNA gene, sampling date and location, and supporting literature. The database currently covers 7857 aligned sequences from more than 450 environmental samples or organisms. Based on a robust phylogenetic analysis, we introduce an operational classification system with multiple phylogenetic levels ranging from superclusters to species-level operational taxonomic units. An integrated pipeline for online sequence alignment and phylogenetic tree construction is also provided. With a user-friendly interface and integrated online bioinformatics tools, this unique resource should be highly valuable for upcoming studies of the biogeography, diversity, distribution and evolution of microbial rhodopsins.

Lagomasino, Isabel T; Zatzick, Douglas F; Chambers, David A

2010-01-01

Limited financial resources, escalating mental health-related costs and opportunities for capitalizing on advances in health information technologies have brought the theme of efficiency to the forefront of mental health services research and clinical practice. In this introductory article to the journal series stemming from the 20th NIMH Mental Health Services Research Conference, we first delineate the need for a new focus on efficiency in both research and clinical practice. Second, we provide preliminary definitions of efficiency for the field and discuss issues related to measurement. Finally, we explore the interface between efficiency in mental health services research and practice and the NIMH strategic objectives of developing improved interventions for diverse populations and enhancing the public health impact of research. Case examples illustrate how perspectives from dissemination and implementation research may be used to maximize efficiencies in the development and implementation of new service delivery models. Allowing findings from the dissemination and implementation field to permeate and inform clinical practice and research may facilitate more efficient development of interventions and enhance the public health impact of research.

Nonhuman animals are ubiquitous to human life, and permeate a diversity of social contexts by providing humans with food and clothing, serving as participants in research, improving healing, and offering entertainment, leisure, and companionship. Despite the impact that animals have on human lives and vice versa, the field of psychology has barely touched upon the topic of human-animal relations as an important domain of human activity. We review the current state of research on human-animal relations, showing how this body of work has implications for a diverse range of psychological themes including evolutionary processes, development, normative factors, gender and individual differences, health and therapy, and intergroup relations. Our aim is to highlight human-animal relations as a domain of human life that merits theoretical and empirical attention from psychology as a discipline.

Translating Population Difference: The Use and Re-Use of Genetic Ancestry in Brazilian Cancer Genetics

PubMed Central

Gibbon, Sahra

2016-01-01

ABSTRACT In the past ten years, there has been an expansion of scientific interest in population genetics linked to both understanding histories of human migration and the way that population difference and diversity may account for and/or be implicated in health and disease. In this article, I examine how particular aspects of a globalizing research agenda related to population differences and genetic ancestry are taken up in locally variant ways in the nascent field of Brazilian cancer genetics. Drawing on a broad range of ethnographic data from clinical and nonclinical contexts in the south of Brazil, I examine the ambiguities that attention to genetic ancestry generates, so revealing the disjunctured and diverse ways a global research agenda increasingly orientated to questions of population difference and genetic ancestry is being used and reused.

Recent progress in henipavirus research: molecular biology, genetic diversity, animal models.

PubMed

Rockx, Barry; Winegar, Richard; Freiberg, Alexander N

2012-08-01

Nipah and Hendra virus are members of a newly identified genus of emerging paramyxoviruses, the henipaviruses. Both viruses have the ability to cause severe pulmonary infection and severe acute encephalitis. Following their discovery in the 1990s, outbreaks caused by these zoonotic paramyxoviruses have been associated with high public health and especially economic threat potential. Currently, only geographic groupings in Asia and Australia have been described for the henipaviruses. However, while few viral isolates are available and more detailed characterization is necessary, there has been recent evidence that divergent henipaviruses might be present on the African continent. This review endeavours to capture recent advances in the field of henipavirus research, with a focus on genome structure and replication mechanisms, reservoir hosts, genetic diversity, pathogenesis and animal models.

2017-01-01

Two independent surveys of PhD students in STEM fields at the University of California, Berkeley, indicate that underrepresented minorities (URMs) publish at significantly lower rates than non-URM males, placing the former at a significant disadvantage as they compete for postdoctoral and faculty positions. Differences as a function of gender reveal a similar, though less consistent, pattern. A conspicuous exception is Berkeley's College of Chemistry, where publication rates are tightly clustered as a function of ethnicity and gender, and where PhD students experience a highly structured program that includes early and systematic involvement in research, as well as clear expectations for publishing. Social science research supports the hypothesis that this more structured environment hastens the successful induction of diverse groups into the high-performance STEM academic track.

Islamic perspective on human cloning and stem cell research.

Larijani, B; Zahedi, F

2004-12-01

Recent advances in the field of cloning and stem cell research have introduced new hope for treatment of serious diseases. But this promise has been accompanied by enormous questions. Currently, cloning is a matter of public discussion. It is rare that a field of science causes debate and challenge not only among scientists but also among ethicists, religious scholars, governments, and politicians. One important concern is religious arguments. Various religions have different attitudes toward the morality of these subjects; even within a particular religious tradition there is a diversity of opinions. The following article briefly reviews Islamic perspectives about reproductive/therapeutic cloning and stem cell research. The majority of Muslim jurists distinguish between reproductive and therapeutic cloning.

Two independent surveys of PhD students in STEM fields at the University of California, Berkeley, indicate that underrepresented minorities (URMs) publish at significantly lower rates than non-URM males, placing the former at a significant disadvantage as they compete for postdoctoral and faculty positions. Differences as a function of gender reveal a similar, though less consistent, pattern. A conspicuous exception is Berkeley’s College of Chemistry, where publication rates are tightly clustered as a function of ethnicity and gender, and where PhD students experience a highly structured program that includes early and systematic involvement in research, as well as clear expectations for publishing. Social science research supports the hypothesis that this more structured environment hastens the successful induction of diverse groups into the high-performance STEM academic track. PMID:28380061

Genotypic diversity effects on the performance of Taraxacum officinale populations increase with time and environmental favorability.

PubMed

Drummond, Emily B M; Vellend, Mark

2012-01-01

Within-population genetic diversity influences many ecological processes, but few studies have examined how environmental conditions may impact these short-term diversity effects. Over four growing seasons, we followed experimental populations of a clonal, ubiquitous weed, Taraxacum officinale, with different numbers of genotypes in relatively favorable fallow field and unfavorable mowed lawn environmental treatments. Population performance (measured as total leaf area, seed production or biomass) clearly and consistently increased with diversity, and this effect became stronger over the course of the experiment. Diversity effects were stronger, and with different underlying mechanisms, in the fallow field versus the mowed lawn. Large genotypes dominated in the fallow field driving overyielding (via positive selection effects), whereas in the mowed lawn, where performance was limited by regular disturbance, there was evidence for complementarity among genotypes (with one compact genotype in particular performing better in mixture than monoculture). Hence, we predict stronger genotypic diversity effects in environments where intense intraspecific competition enhances genotypic differences. Our four-year field experiment plus seedling establishment trials indicate that genotypic diversity effects have far-reaching and context-dependent consequences across generations.

Despite the increasingly global nature of health care, much of the research about journal rankings and directions for future research in health care management is from a United States based viewpoint. There is a lack of information about influential journals and trends for health care management research from a global perspective. This exploratory study gathered the opinions of health care management researchers from 17 countries regarding which journals are considered most influential, popular research topics and areas needing more attention from the research community. An online survey was sent to individuals in high-income Organisation for Economic Co-operation and Development countries who were identified through author relationships, academic institution websites, editorial boards of international journals, and academic and practitioner associations in the countries of interest. Results indicate that journal rankings vary substantially from prior published studies evaluating health care management journals and international ranking lists, and the list of influential journals includes a much more diverse array of publications. Respondents also indicated a diverse number of topics for current and future research, highlighting the global complexity of the field. The implications of this study are valuable to scholars evaluating outlets for disseminating research, and highlighting areas for collaborative research in health care management globally.

Community-based participatory research (CBPR) is an approach to research and evaluation that is receiving increased attention in the field of public health. Our report discusses the application of this approach to research and evaluation with an Early Head Start (EHS) program in Pittsburgh, Pa. Our primary purpose is to illustrate the key elements that contributed to effective collaboration among researchers, EHS practitioners, and parents of EHS children in the conduct of the study. The focus is not on research findings but on research process. Our goal is to make the practices of CBPR visible and explicit so they can be analyzed, further developed, and effectively applied to a range of public health issues in a diversity of community contexts.

Sequence-related amplified polymorphism (SRAP) markers: A potential resource for studies in plant molecular biology(1.).

PubMed

Robarts, Daniel W H; Wolfe, Andrea D

2014-07-01

In the past few decades, many investigations in the field of plant biology have employed selectively neutral, multilocus, dominant markers such as inter-simple sequence repeat (ISSR), random-amplified polymorphic DNA (RAPD), and amplified fragment length polymorphism (AFLP) to address hypotheses at lower taxonomic levels. More recently, sequence-related amplified polymorphism (SRAP) markers have been developed, which are used to amplify coding regions of DNA with primers targeting open reading frames. These markers have proven to be robust and highly variable, on par with AFLP, and are attained through a significantly less technically demanding process. SRAP markers have been used primarily for agronomic and horticultural purposes, developing quantitative trait loci in advanced hybrids and assessing genetic diversity of large germplasm collections. Here, we suggest that SRAP markers should be employed for research addressing hypotheses in plant systematics, biogeography, conservation, ecology, and beyond. We provide an overview of the SRAP literature to date, review descriptive statistics of SRAP markers in a subset of 171 publications, and present relevant case studies to demonstrate the applicability of SRAP markers to the diverse field of plant biology. Results of these selected works indicate that SRAP markers have the potential to enhance the current suite of molecular tools in a diversity of fields by providing an easy-to-use, highly variable marker with inherent biological significance.

Biosynthetic Polymers as Functional Materials

PubMed Central

2016-01-01

The synthesis of functional polymers encoded with biomolecules has been an extensive area of research for decades. As such, a diverse toolbox of polymerization techniques and bioconjugation methods has been developed. The greatest impact of this work has been in biomedicine and biotechnology, where fully synthetic and naturally derived biomolecules are used cooperatively. Despite significant improvements in biocompatible and functionally diverse polymers, our success in the field is constrained by recognized limitations in polymer architecture control, structural dynamics, and biostabilization. This Perspective discusses the current status of functional biosynthetic polymers and highlights innovative strategies reported within the past five years that have made great strides in overcoming the aforementioned barriers.

Computational Lipidomics and Lipid Bioinformatics: Filling In the Blanks.

PubMed

Pauling, Josch; Klipp, Edda

2016-12-22

Lipids are highly diverse metabolites of pronounced importance in health and disease. While metabolomics is a broad field under the omics umbrella that may also relate to lipids, lipidomics is an emerging field which specializes in the identification, quantification and functional interpretation of complex lipidomes. Today, it is possible to identify and distinguish lipids in a high-resolution, high-throughput manner and simultaneously with a lot of structural detail. However, doing so may produce thousands of mass spectra in a single experiment which has created a high demand for specialized computational support to analyze these spectral libraries. The computational biology and bioinformatics community has so far established methodology in genomics, transcriptomics and proteomics but there are many (combinatorial) challenges when it comes to structural diversity of lipids and their identification, quantification and interpretation. This review gives an overview and outlook on lipidomics research and illustrates ongoing computational and bioinformatics efforts. These efforts are important and necessary steps to advance the lipidomics field alongside analytic, biochemistry, biomedical and biology communities and to close the gap in available computational methodology between lipidomics and other omics sub-branches.

Understanding Regional Effects on Climate Change and Multidisciplinary Approarch for Coping Strategies - Case Study at Rural Village in Sub-Saharan Africa -

Yoshimura, M.; Yamashita, M.

2018-04-01

This paper describes on understanding the regional effects on global climate change and subsistence farmers' coping strategies through our field investigation and multidimensional data analysis from the resilience point of view. The major research question of this study is to understand what actions villagers took as the coping strategy against the heavy rainfall shock caused by climate change. Our research interest is how geospatial information technique can contribute to this research question. The study area is located in Sinazongwe district, Southern province of Zambia. As for the field investigation, we set the study sites A, B and C where are located in the lower terrace, middle escarpment and upper terrace, respectively. In the rainy season of 2007/2008, our study site had a heavy rainfall and many crop fields were damaged. In this crop year, the annual rainfalls in site A and C were 1442 mm/year and 1332 mm/year respectively. This is about two times different with the long term average of rainfall 694.9 mm/year in Sinazongwe district. It is confirmed that approximately 20 % of crop fields were damaged by heavy rainfall through our field investigation. It was so severe negative consequences for all of villages because about 80 % of whole damaged crop fields were maize fields. Maize is staple food in this region. Here, we have analysed and discussed how villagers cope from the serious damage of crops. The maize harvest varies every year depending on rainfall and topographic position. If a farmer possesses maize fields at various topographic positions, they can avoid severe negative consequences of climate variability such as drought or heavy rainfall. However, not all farmers have access to fields at various topographic positions. It is important to know where each household's characteristics when we consider their strategy of livelihood for climate variabilities. Through this study, we confirmed the way to strengthen resilience of subsistence farmers as follows: it is necessary to prepare variable crops and emergency food stock with not only diverse but also composite social institution. The resilient society seems to be the society with insurance such as adaptation ability against environmental shock caused by climate change. From the agricultural production point of view, both diversity and yield ability are also important.

Dammann, O

2006-02-01

Perinatal brain damage has a diverse and complex aetiology. Over the past decades, much progress has been made in this research field. In this article, I offer a discussion of seven dimensions of aetiological perinatal brain damage research: (1) hypoxia-ischaemia vs. inflammation; (2) "classic" vs. "remote" intrauterine infection; (3) focal vs. diffuse white matter damage; (4) maternal vs. foetal inflammatory response; (5) clinical vs. experimental data; (6) bacterial vs. viral infection; and (7) preterm vs. term delivery. Despite these complexities, it is hoped that obstetricians, neonatologists, and neuropaediatricians will agree on a perinatal neuroprotective strategy in the near future.

As the field of education of the d/Deaf and hard of hearing (d/Dhh) continues to diversify, postsecondary institutions must pay close attention not only to the changing needs of d/Dhh students but to the practitioners they are preparing to serve this population. Students who are d/Dhh and come from homes where a language other than English or American Sign Language is used--d/Dhh Multilingual Learners (DMLs)--constitute 19.4%-35.0% of the d/Dhh student population (Gallaudet Research Institute, 2013). In the present article, part of a special American Annals of the Deaf issue on DMLs, the authors review demographic trends, examine the theory behind teacher effectiveness and culturally responsive teaching, provide examples from research on effective components of teacher preparation programs and discuss how they align with the field's certification standards, and recommend practices for programs and teachers to meet these standards within the field's ever-changing landscape.

Visual analytics as a translational cognitive science.

PubMed

Fisher, Brian; Green, Tera Marie; Arias-Hernández, Richard

2011-07-01

Visual analytics is a new interdisciplinary field of study that calls for a more structured scientific approach to understanding the effects of interaction with complex graphical displays on human cognitive processes. Its primary goal is to support the design and evaluation of graphical information systems that better support cognitive processes in areas as diverse as scientific research and emergency management. The methodologies that make up this new field are as yet ill defined. This paper proposes a pathway for development of visual analytics as a translational cognitive science that bridges fundamental research in human/computer cognitive systems and design and evaluation of information systems in situ. Achieving this goal will require the development of enhanced field methods for conceptual decomposition of human/computer cognitive systems that maps onto laboratory studies, and improved methods for conducting laboratory investigations that might better map onto real-world cognitive processes in technology-rich environments.

Mentoring experiences and programmes are becoming increasingly recognised as important by those engaged in capacity strengthening in global health research. Using a primarily qualitative study design, we studied three experiences of mentorship and eight mentorship programmes for early career global health researchers based in high-income and low- and middle-income countries. For the latter, we drew upon programme materials, existing unpublished data and more formal mixed-method evaluations, supplemented by individual email questionnaire responses. Research team members wrote stories, and the team assembled and analysed them for key themes. Across the diverse experiences and programmes, key emergent themes included: great mentors inspire others in an inter-generational cascade, mentorship is transformative in personal and professional development and involves reciprocity, and finding the right balance in mentoring relationships and programmes includes responding creatively to failure. Among the challenges encountered were: struggling for more level playing fields for new health researchers globally, changing mindsets in institutions that do not have a culture of mentorship and building collaboration not competition. Mentoring networks spanning institutions and countries using multiple virtual and face-to-face methods are a potential avenue for fostering organisational cultures supporting quality mentorship in global health research.

Neuroethics, confidentiality, and a cultural imperative in early onset Alzheimer disease: a case study with a First Nation population

PubMed Central

2013-01-01

The meaningful consideration of cultural practices, values and beliefs is a necessary component in the effective translation of advancements in neuroscience to clinical practice and public discourse. Society’s immense investment in biomedical science and technology, in conjunction with an increasingly diverse socio-cultural landscape, necessitates the study of how potential discoveries in neurodegenerative diseases such as Alzheimer disease are perceived and utilized across cultures. Building on the work of neuroscientists, ethicists and philosophers, we argue that the growing field of neuroethics provides a pragmatic and constructive pathway to guide advancements in neuroscience in a manner that is culturally nuanced and relevant. Here we review a case study of one issue in culturally oriented neuroscience research where it is evident that traditional research ethics must be broadened and the values and needs of diverse populations considered for meaningful and relevant research practices. A global approach to neuroethics has the potential to furnish critical engagement with cultural considerations of advancements in neuroscience. PMID:24131854

The fundamental ISS payload integration philosophy, processes and capabilities were established in the context of how NASA science programs were conducted and executed in the early 1990 s. Today, with the designation of the United States (US) portion of ISS as a National Lab, the ISS payload customer base is growing to include other government agencies, private and commercial research. The fields of research are becoming more diverse expanding from the NASA centric physical, materials and human research sciences to test beds for exploration and technology demonstration, biology and biotechnology, and as an Earth and Space science platform. This new customer base has a broader more diverse set of expectations and requirements for payload design, verification, integration, test, training, and operations. One size fits all processes are not responsive to this broader customer base. To maintain an organization s effectiveness it must listen to its customers, understand their needs, learn from its mistakes, and foster an environment of continual process improvement. The ISS Payloads office is evolving to meet these new customer expectations.

We describe two programs, CAMPARE and Cal-Bridge, with the common mission of increasing participation of groups traditionally underrepresented in astronomy, through summer research opportunities, in the case of CAMPARE, scholarships in the case of Cal-Bridge, and significant mentoring in both programs, leading to an increase in their numbers successfully pursuing a PhD in the field.In 6 years, the CAMPARE program has sent 62 students, >85% from underrepresented groups, to conduct summer research at one of twelve major research institutions in California, Arizona, and Wyoming. The graduation rate among CAMPARE scholars is 97%, and of the 37 CAMPARE scholars who have graduated with a Bachelor's degree, almost 60% (21) have completed or are pursuing graduate education in astronomy or a related field, at institutions including UCLA, USC, UC Riverside, Stanford, Univ. of Rochester, Georgia Tech, Kent State, Indiana Univ., Univ. of Oregon, Syracuse, and the Fisk-Vanderbilt Master's-to-PhD program. The Cal-Bridge program is a CSU-UC Bridge program comprised of faculty form 5 University of California (UC), 8 California State University (CSU), and 8 California Community College (CCC) campuses in Southern California. Cal-Bridge provides much deeper mentoring and professional development experiences over the last two years of undergraduate and first year of graduate school to students from this diverse network of higher education institutions. Cal-Bridge Scholars benefit from financial support, intensive, joint mentoring by CSU and UC faculty, professional development workshops, and exposure to research opportunities at the participating UC campuses.

A framework for diversifying recommendation lists by user interest expansion.

PubMed

Zhang, Zhu; Zheng, Xiaolong; Zeng, Daniel Dajun

2016-08-01

Recommender systems have been widely used to discover users' preferences and recommend interesting items to users during this age of information load. Researchers in the field of recommender systems have realized that the quality of a top-N recommendation list involves not only relevance but also diversity. Most traditional recommendation algorithms are difficult to generate a diverse item list that can cover most of his/her interests for each user, since they mainly focus on predicting accurate items similar to the dominant interests of users. Additionally, they seldom exploit semantic information such as item tags and users' interest labels to improve recommendation diversity. In this paper, we propose a novel recommendation framework which mainly adopts an expansion strategy of user interests based on social tagging information. The framework enhances the diversity of users' preferences by expanding the sizes and categories of the original user-item interaction records, and then adopts traditional recommendation models to generate recommendation lists. Empirical evaluations on three real-world data sets show that our method can effectively improve the accuracy and diversity of item recommendation.

Unified Time and Frequency Picture of Ultrafast Atomic Excitation in Strong Laser Fields

2017-01-01

Excitation and ionization in strong laser fields lies at the heart of such diverse research directions as high-harmonic generation and spectroscopy, laser-induced diffraction imaging, emission of femtosecond electron bunches from nanotips, self-guiding, filamentation and mirrorless lasing during propagation of light in atmospheres. While extensive quantum mechanical and semiclassical calculations on strong-field ionization are well backed by sophisticated experiments, the existing scattered theoretical work aiming at a full quantitative understanding of strong-field excitation lacks experimental confirmation. Here we present experiments on strong-field excitation in both the tunneling and multiphoton regimes and their rigorous interpretation by time dependent Schrödinger equation calculations, which finally consolidates the seemingly opposing strong-field regimes with their complementary pictures. Most strikingly, we observe an unprecedented enhancement of excitation yields, which opens new possibilities in ultrafast strong-field control of Rydberg wave packet excitation and laser intensity characterization.

How Are Academic Age, Productivity and Collaboration Related to Citing Behavior of Researchers?

PubMed Central

Milojević, Staša

2012-01-01

References are an essential component of research articles and therefore of scientific communication. In this study we investigate referencing (citing) behavior in five diverse fields (astronomy, mathematics, robotics, ecology and economics) based on 213,756 core journal articles. At the macro level we find: (a) a steady increase in the number of references per article over the period studied (50 years), which in some fields is due to a higher rate of usage, while in others reflects longer articles and (b) an increase in all fields in the fraction of older, foundational references since the 1980s, with no obvious change in citing patterns associated with the introduction of the Internet. At the meso level we explore current (2006–2010) referencing behavior of different categories of authors (21,562 total) within each field, based on their academic age, productivity and collaborative practices. Contrary to some previous findings and expectations we find that senior researchers use references at the same rate as their junior colleagues, with similar rates of re-citation (use of same references in multiple papers). High Modified Price Index (MPI, which measures the speed of the research front more accurately than the traditional Price Index) of senior authors indicates that their research has the similar cutting-edge aspect as that of their younger colleagues. In all fields both the productive researchers and especially those who collaborate more use a significantly lower fraction of foundational references and have much higher MPI and lower re-citation rates, i.e., they are the ones pushing the research front regardless of researcher age. This paper introduces improved bibliometric methods to measure the speed of the research front, disambiguate lead authors in co-authored papers and decouple measures of productivity and collaboration.

2018-01-01

Graduate Resources for Advancing Diversity with Maryland’s Astronomy and Physics (GRAD-MAP), builds connections between UMD and mid-Atlantic HBCUs, Minority-Serving Institutions (MSIs), and community colleges. We use seminars, forums, and workshops to foster a diverse community of undergraduates prepared to succeed in graduate school, inclusion-minded graduate student mentors, and faculty versed in the experiences of students at MSIs and the need for changes in the fields of physics and astronomy. Now in its fifth year, GRAD-MAP remains a graduate-student-powered initiative with a three-pronged approach: 1) Fall Collaborative Seminars, 2) A Winter Workshop, and 3) A Summer Scholars Program. This coherent set of programming allows GRAD-MAP to do more than just increase the numbers of minority students participating in astronomy and physics research (or worse, simply shuffle around students who already are or would be active in research). GRAD-MAP is committed to identifying students who are otherwise underserved or overlooked by the traditional academic pipeline, not only to get them on the path to be successful undergraduate researchers and eventual graduate applicants, but also to make substantial, sustainable efforts toward making the climate of academic physics and astronomy more inclusive to them and all other underrepresented minority students.

The existence of street as a place to perform various human activities becomes an important issue nowadays. In the last few decades, cars and motorcycles dominate streets in various cities in the world. On the other hand, human activity on the street is the determinant of the city livability. Previous research has pointed out that if there is lots of human activity in the street, then the city will be interesting. Otherwise, if the street has no activity, then the city will be boring. Learning from that statement, now various cities in the world are developing the concept of livable streets. Livable streets shown by diversity of human activities conducted in the streets’ pedestrian space. In Yogyakarta, one of the streets shown diversity of human activities is Jalan Kemasan. This study attempts to determine the physical factors of pedestrian space affecting the livability in Jalan Kemasan Yogyakarta through spatial analysis. Spatial analysis was performed by overlay technique between liveable point (activity diversity) distribution map and variable distribution map. Those physical pedestrian space research variable included element of shading, street vendors, building setback, seat location, divider between street and pedestrian way, and mixed use building function. More diverse the activity of one variable, then those variable are more affected then others. Overlay result then strengthened by field observation to qualitatively ensure the deduction. In the end, this research will provide valuable input for street and pedestrian space planning that is comfortable for human activities.

Comparing diversities between groups is a task biologists are frequently faced with, for example in ecological field trials or when dealing with metagenomics data. However, researchers often waver about which measure of diversity to choose as there is a multitude of approaches available. As Jost (2008, Molecular Ecology, 17, 4015) has pointed out, widely used measures such as the Shannon or Simpson index have undesirable properties which make them hard to compare and interpret. Many of the problems associated with the use of these 'raw' indices can be corrected by transforming them into 'true' diversity measures. We introduce a technique that allows the comparison of two or more groups of observations and simultaneously tests a user-defined selection of a number of 'true' diversity measures. This procedure yields multiplicity-adjusted P-values according to the method of Westfall and Young (1993, Resampling-Based Multiple Testing: Examples and Methods for p-Value Adjustment, 49, 941), which ensures that the rate of false positives (type I error) does not rise when the number of groups and/or diversity indices is extended. Software is available in the R package 'simboot'. © 2012 Blackwell Publishing Ltd.

Fast and nondestructive approaches of measuring plant species diversity have been a subject of excessive scientific curiosity and disquiet to environmentalists and field ecologists worldwide. In this study, we measured the hyperspectral reflectances and plant species diversity indices at a fine scale (0.8 meter) in central Hunshandak Sandland of Inner Mongolia, China. The first-order derivative value (FD) at each waveband and 37 hyperspectral indices were used to assess plant species diversity. Results demonstrated that the stepwise linear regression of FD can accurately estimate the Simpson (R 2  = 0.83), Pielou (R 2  = 0.87) and Shannon-Wiener index (R 2  = 0.88). Stepwise linear regression of FD (R 2  = 0.81, R 2  = 0.82) and spectral vegetation indices (R 2  = 0.51, R 2  = 0.58) significantly predicted the Margalef and Gleason index. It was proposed that the Simpson, Pielou and Shannon-Wiener indices, which are widely used as plant species diversity indicators, can be precisely estimated through hyperspectral indices at a fine scale. This research promotes the development of methods for assessment of plant diversity using hyperspectral data.

Developing High School Geoscientists through Summer Internships

High school students in the San Francisco Bay Area have the opportunity to contribute to Earth sciences research during the summer at Stanford University. The School of Earth Sciences hosts about 25 high school students each summer to support ongoing research, through more than just washing glassware. To increase diversity in the geosciences, we select students from diverse backgrounds through an application process which lessens the burden on busy faculty. The students work for 15-20 hours per week under the supervision of graduate students or postdoctoral fellows. The supervisors come to value the interns for a few reasons: not only are they getting some extra help with their research, but they are getting teaching experience in an informal but powerful way and supervising the interns' work over the summer. Another key part of the internship is bringing all of the interns together regularly. Whether it is for career talks, lab tours or field trip, high school students find kindred spirits in the group. Another important reason for weekly gatherings is to introduce the students to the wide field of Earth sciences and the different approaches and paths that scientists take. The summer ends with a culminating event where interns make short informal presentations about their research which give them an opportunity to articulate the big questions they have been helping to answer. Some interns are also invited to present a poster in a session for high school students at the Fall AGU meeting. These experiences of working in the laboratory and communicating about the research are part of the world of Earth sciences that are absent for most youth. The high school internships foster good will between Stanford and the local communities, help develop a more Earth and environmentally knowledgeable public and may have a long-term affect on diversifying the geosciences by exposing more young people to these fields.

The State of the Science in Spirituality and Palliative Care was convened to address the current landscape of research at the intersection of spirituality and palliative care and to identify critical next steps to advance this field of inquiry. Part I of the SOS-SPC two-part series focuses on questions of 1) What is spirituality? 2) What methodological and measurement issues are most salient for research in palliative care? And 3) What is the evidence relating spirituality and health outcomes? After describing current evidence we make recommendations for future research in each of the three areas of focus. Results show wide variance in the ways spirituality is operationalized and the need for definition and conceptual clarity in research in spirituality. Furthermore, the field would benefit from hypothesis-driven outcomes research based on a priori specification of the spiritual dimensions under investigation and their longitudinal relationship with key palliative outcomes, the use of validated measures of predictors and outcomes, and rigorous assessment of potential confounding variables. Finally, results highlight the need for research in more diverse populations. Published by Elsevier Inc.

Advancing Earth System Science Literacy and Preparing the Future Geoscience Workforce Through Strategic Investments at the National Science Foundation (Invited)

The National Science Foundation (NSF) is an independent federal agency created 60 years ago by the U.S. Congress "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense…" NSF is the primary funding agency in the U.S. to support basic, frontier research across all fields in science, engineering, and education, except for medical sciences. With a FY 2011 budget request of more than $955 million, the NSF Directorate for Geosciences (GEO) is the principle source of federal funding for university-based fundamental research in the geosciences and preparation of the next generation of geoscientists. Since its inception, GEO has supported the education and training of a diverse and talented pool of future scientists, engineers, and technicians in the Earth, Ocean, Atmospheric and Geospatial Sciences sub-fields, through support of graduate research assistants, post-doctoral fellows, and undergraduate research experiences. In the late 1990’s and early 2000’s, GEO initiated several programs that expanded these investments to also support improvements in pre-college and undergraduate geoscience education through a variety of mechanisms (e.g., professional development support for K-12 teachers, development of innovative undergraduate curricula, and scientist-mentored research experiences for elementary and secondary students). In addition to GEO’s Geoscience Education (GeoEd), Opportunities for Enhancing Diversity in the Geosciences (OEDG), Global Learning and Observations to Benefit the Environment (GLOBE), and Geoscience Teacher Training (GEO-Teach) programs, GEO participates in a number of cross-Foundation programs, including the Research Experiences for Undergraduates (REU), Integrative Graduate Education and Research Traineeship (IGERT), Ethics Education in Science and Engineering (EESE), NSF Graduate STEM Fellows in K-12 Education (GK-12), and Partnerships for International Research and Education (PIRE) programs, and the new Climate Change Education Partnership (CCEP) program. Many broader impact activities associated with individual research grants supported by GEO contribute to the mix, through integration of research and education. Improving access to high quality geoscience education, developing educational resources and pedagogies that reflect current understandings based on cognitive research on how people learn science in formal and informal settings, cultivating a diverse talent pool for the future, and developing robust mechanisms to evaluate the quality of these various approaches and tools are challenges faced by the entire geosciences research and education community, not just NSF/GEO. In the past two years, GEO has worked collaboratively with the Education and Human Resources (EHR) Directorate, and sister agencies NOAA and NASA, to establish a new GEO Education and Diversity Strategic Framework, that will guide our investments in the future, and identify opportunities for a more cohesive, collaborative, and synergistic approach across NSF and the federal government. Details of this new strategic framework, results of recent program evaluations, and their implications for future NSF/GEO education program funding will be discussed.

About soil cover heterogeneity of agricultural research stations' experimental fields

2013-04-01

Depending on local pedo-ecological conditions (topography, (geo) diversity of soil parent material, meteorological conditions) the patterns of soil cover and plant cover determined by soils are very diverse. Formed in the course of soil-plant mutual relationship, the natural ecosystems are always influenced to certain extent by the other local soil forming conditions or they are site specific. The agricultural land use or the formation of agro-ecosystems depends foremost on the suitability of soils for the cultivation of feed and food crops. As a rule, the most fertile or the best soils of the area, which do not present any or present as little as possible constraints for agricultural land use, are selected for this purpose. Compared with conventional field soils, the requirements for the experimental fields' soil cover quality are much higher. Experimental area soils and soil cover composition should correspond to local pedo-ecological conditions and, in addition to that, represent the soil types dominating in the region, whereas the fields should be as homogeneous as possible. The soil cover heterogeneity of seven arable land blocks of three research stations (Jõgeva, Kuusiku and Olustvere) was studied 1) by examining the large scale (1:10 000) digital soil map (available via the internet), and 2) by field researches using the transect method. The stages of soils litho-genetic and moisture heterogeneities were estimated by using the Estonian normal soils matrix, however, the heterogeneity of top- and subsoil texture by using the soil texture matrix. The quality and variability of experimental fields' soils humus status, was studied more thoroughly from the aspect of humus concentration (g kg-1), humus cover thickness (cm) and humus stocks (Mg ha-1). The soil cover of Jõgeva experimental area, which presents an accumulative drumlin landscape (formed during the last glacial period), consist from loamy Luvisols and associated to this Cambisols. In Kuusiku area, which landscape is characterized by till and limestone plains with thin Quaternary cover, the soil cover is more heterogeneous than in previous area. Kuusiku soil cover is more variegated by the soil texture and as well as by the genesis of soils. In addition to Cambisols, Leptosols, Gleysols and Luvisols may be found here as well. The dominating soils in Olustvere research area, which is situated on wavy upland plateau, are Albeluvisols.

The diversity and the feeding guilds of birds in three different habitats (secondary forest, oil palm plantation and paddy field) were investigated in riparian areas of the Kerian River Basin (KRB), Perak, Malaysia. Point-count observation and mist-netting methods were used to determine bird diversity and abundance. A total of 132 species of birds from 46 families were recorded in the 3 habitats. Species diversity, measured by Shannon's diversity index, was 3.561, 3.183 and 1.042 in the secondary forest, the paddy field and the oil palm plantation, respectively. The vegetation diversity and the habitat structure were important determinants of the number of bird species occurring in an area. The relative abundance of the insectivore, insectivore-frugivore and frugivore guilds was greater in the forest than in the monoculture plantation. In contrast, the relative abundance of the carnivore, granivore and omnivore guilds was higher in the plantation. The results of the study show that the conversion of forest to either oil palm plantation or paddy fields produced a decline in bird diversity and changes in the distribution of bird feeding guilds.

Genotypic Diversity Effects on the Performance of Taraxacum officinale Populations Increase with Time and Environmental Favorability

Drummond, Emily B. M.; Vellend, Mark

2012-01-01

Within-population genetic diversity influences many ecological processes, but few studies have examined how environmental conditions may impact these short-term diversity effects. Over four growing seasons, we followed experimental populations of a clonal, ubiquitous weed, Taraxacum officinale, with different numbers of genotypes in relatively favorable fallow field and unfavorable mowed lawn environmental treatments. Population performance (measured as total leaf area, seed production or biomass) clearly and consistently increased with diversity, and this effect became stronger over the course of the experiment. Diversity effects were stronger, and with different underlying mechanisms, in the fallow field versus the mowed lawn. Large genotypes dominated in the fallow field driving overyielding (via positive selection effects), whereas in the mowed lawn, where performance was limited by regular disturbance, there was evidence for complementarity among genotypes (with one compact genotype in particular performing better in mixture than monoculture). Hence, we predict stronger genotypic diversity effects in environments where intense intraspecific competition enhances genotypic differences. Our four-year field experiment plus seedling establishment trials indicate that genotypic diversity effects have far-reaching and context-dependent consequences across generations. PMID:22348004

Toxicology as a nanoscience? – Disciplinary identities reconsidered

PubMed Central

Kurath, Monika; Maasen, Sabine

2006-01-01

Toxicology is about to establish itself as a leading scientific discipline in addressing potential health effects of materials on the nanosize level. Entering into a cutting-edge field, has an impact on identity-building processes within the involved academic fields. In our study, we analyzed the ways in which the entry into the field of nanosciences impacts on the formation of disciplinary identities. Using the methods of qualitative interviews with particle toxicologists in Germany, Holland, Switzerland and the USA, we could demonstrate that currently, toxicology finds itself in a transitional phase. The development of its disciplinary identity is not yet clear. Nearly all of our interview partners stressed the necessity of repositioning toxicology. However, they each suggested different approaches. While one part is already propagandizing the establishment of a new discipline – 'nanotoxicology'- others are more reserved and are demanding a clear separation of traditional and new research areas. In phases of disciplinary new-orientation, research communities do not act consistently. Rather, they establish diverse options. By expanding its disciplinary boundaries, participating in new research fields, while continuing its previous research, and only vaguely defining its topics, toxicology is feeling its way into the new fields without giving up its present self-conception. However, the toxicological research community is also discussing a new disciplinary identity. Within this, toxicology could develop from an auxiliary into a constitutive position, and take over a basic role in the cognitive, institutional and social framing of the nanosciences. PMID:16646961

Research Experience for Undergraduates (REU) programs commonly serve students already committed to careers in science. To spark student interest in the sciences early in their college career, the CIRES diversity initiative teamed with the Boulder Creek Critical Zone Observatory to build an REU for Colorado community college students. A group of 7 students was selected from consideration of diversity, prior training, and personal statements. Each student was paired with a research science mentor. Field excursions and team-building exercises filled the first week of the 8-week program. Students received weekly training in science communication, responsible conduct of research, use of spreadsheet and graphing software, and statistical analysis. Each student presented their research in a poster session, an oral presentation, and a written report. Several aspects of this pilot program worked well. The students formed a very supportive cohort, despite the fact that they were not in residence. Cohesion grew out of the immersion in field trips, and was reinforced with weekly check-ins. The trainings were essential for seeing projects through to written and oral presentations. Teaming students for fieldwork was an effective strategy to build support, and reduce mentor fatigue. Each student produced useful data. In the future, we would include a workshop on personal finances to address a clear need. Transportation support will be provided. A residential program might attract some but could preclude participation of students with families or other life-issues. Personal tutoring tailored to research projects would address low math skills. All 7 students completed the program; several elected to submit to the undergraduate virtual poster session at Fall AGU. Students all reported enormous personal and academic growth. Some are discussing transfer and graduate school opportunities with their mentors. The enthusiasm and appreciation of the students was unparalleled.

Concluding a two-part American Annals of the Deaf special issue on deafness and diversity (DAD), the editors provide reflections and guidance to the field regarding d/Deaf and hard of hearing (d/Dhh) children with a disability (DWD; e.g., learning or intellectual disability, autism) and d/Dhh children from homes where parents use a language other than English or American Sign Language (d/Dhh Multilingual Learners; DMLs). Contributing authors addressed the application of theory, research, and practice to five topics: (a) early intervention, (b) communication/language, (c) assessment, (d) transition, (e) teacher preparation. An overview of the main recommendations of the contributors and editors is presented in an effort to advance research and pedagogy with these learners. In conclusion, the editors discuss the "Radical Middle" approach (Easterbrooks & Maiorana-Basas, 2015) to working with students who are DAD: providing learners with all options for academic, social, and emotional success.

A Low-Cost, Hands-on Module to Characterize Antimicrobial Compounds Using an Interdisciplinary, Biophysical Approach

2015-01-01

We have developed a hands-on experimental module that combines biology experiments with a physics-based analytical model in order to characterize antimicrobial compounds. To understand antibiotic resistance, participants perform a disc diffusion assay to test the antimicrobial activity of different compounds and then apply a diffusion-based analytical model to gain insights into the behavior of the active antimicrobial component. In our experience, this module was robust, reproducible, and cost-effective, suggesting that it could be implemented in diverse settings such as undergraduate research, STEM (science, technology, engineering, and math) camps, school programs, and laboratory training workshops. By providing valuable interdisciplinary research experience in science outreach and education initiatives, this module addresses the paucity of structured training or education programs that integrate diverse scientific fields. Its low-cost requirements make it especially suitable for use in resource-limited settings. PMID:25602254

To plan experiments, a biologist needs to evaluate a growing set of empirical findings and hypothetical assertions from diverse fields that use increasingly complex techniques. To address this problem, we operationalized principles (e.g., convergence and consistency) that biologists use to test causal relations and evaluate experimental evidence. With the framework we derived, we then created a free, open-source web application that allows biologists to create research maps, graph-based representations of empirical evidence and hypothetical assertions found in research articles, reviews, and other sources. With our ResearchMaps web application, biologists can systematically reason through the research that is most important to them, as well as evaluate and plan experiments with a breadth and precision that are unlikely without such a tool.

Complex socio-ecological issues, such as climate change have historically been addressed through technical problem solving methods. Yet today, climate science approaches are increasingly accounting for the roles of diverse social perceptions, experiences, cultural norms, and worldviews. In support of this shift, we developed a research program on Hawai'i Island that utilizes knowledge coproduction to integrate the diverse worldviews of natural and cultural resource managers, policy professionals, and researchers within actionable science products. Through their work, local field managers regularly experience discrete land and waterscapes. Additionally, in highly interconnected rural communities, such as Hawai'i Island, managers often participate in the social norms and values of communities that utilize these ecosystems. Such local manager networks offer powerful frameworks within which to co-develop and implement actionable science. We interviewed a diverse set of local managers with the aim of incorporating their perspectives into the development of a collaborative climate change research agenda that builds upon existing professional networks utilized by managers and scientists while developing new research products. We report our manager needs assessment, the development process of our climate change program, our interactive forums, and our ongoing research products. Our needs assessment showed that the managers' primary source of information were other professional colleagues, and our in-person forums informed us that local managers are very interested in interacting with a wider range of networks to build upon their management capacities. Our initial programmatic progress suggests that co-created research products and in-person forums strengthen the capacities of local managers to adapt to change.

Dartmouth College Earth Sciences Mobile Field Program

For the last 50 years the Department of Earth Sciences at Dartmouth College has offered a term-long, undergraduate field program, informally called "the Stretch". A student typically enrolls during fall quarter of his or her junior year soon after choosing a major or minor. The program thus provides valuable field context for courses that a student will take during the remainder of his or her undergraduate career. Unlike many traditional field camps that focus on one particular region, the Stretch is a mobile program that currently travels through Western North America, from the Canadian Rockies to the Grand Canyon. The program spans two and a half months, during which time undergraduates, graduate TAs, and faculty live, work, and learn collaboratively. Dartmouth College faculty members sequentially teach individual 1- to 2-week segments that focus on their interests and expertise; currently, there are a total of eight segments led by eleven faculty members. Consequently, topics are diverse and include economic geology, geobiology, geomorphology, glaciology, glacial geology, geophysics, hydrogeology, paleontology, stratigraphy, structure and tectonics, and volcanology. The field localities are equally varied, including the alpine glaciers of western Alberta, the national parks of Montana, Wyoming and Utah, the eastern Sierra Nevada, the southern Great Basin, and highlight such classic geological field locales as Sheep Mountain in Wyoming's Bighorn Basin, Death Valley, and the Grand Canyon. Overall, the program aims to: 1) give students a broad perspective on the timing and nature of the processes that resulted in the landscape and underlying geology of western North America; and 2) introduce students to a wide variety of geological environments, field techniques, and research equipment. Students emerge from the program with wide-ranging exposure to active research questions as well as a working knowledge of core field skills in the earth sciences. Stretch students spend several weeks conducting traditional multiday mapping of complexly-deformed sedimentary, metamorphic and igneous rocks, and also collect and interpret geobiological, geochemical, geophysical, paleoclimatological, paleontological, and remote-sensing data outside the context of traditional mapping. During the Mono Lake segment, for example, students examine the interaction of ecology and chemistry in alkaline lakes. During the Canadian Rockies segment, students reconstruct Holocene paleoclimate using tree stumps and fossil wood detritus marking former positions of an alpine glacier. While a mobile, wide-ranging field program requires complicated logistics and potentially high per-student costs, the diversity of research topics, geological environments, and field techniques have made it a successful cornerstone of the Dartmouth Earth Sciences major. After the Stretch experience, significant fractions of our students become involved in ongoing faculty research, pursue senior theses, and go on to pursue Earth Sciences graduate degrees.

Use of an airborne lidar system to model plant species composition and diversity of Mediterranean oak forests.

Simonson, William D; Allen, Harriet D; Coomes, David A

2012-10-01

Airborne lidar is a remote-sensing tool of increasing importance in ecological and conservation research due to its ability to characterize three-dimensional vegetation structure. If different aspects of plant species diversity and composition can be related to vegetation structure, landscape-level assessments of plant communities may be possible. We examined this possibility for Mediterranean oak forests in southern Portugal, which are rich in biological diversity but also threatened. We compared data from a discrete, first-and-last return lidar data set collected for 31 plots of cork oak (Quercus suber) and Algerian oak (Quercus canariensis) forest with field data to test whether lidar can be used to predict the vertical structure of vegetation, diversity of plant species, and community type. Lidar- and field-measured structural data were significantly correlated (up to r= 0.85). Diversity of forest species was significantly associated with lidar-measured vegetation height (R(2) = 0.50, p < 0.001). Clustering and ordination of the species data pointed to the presence of 2 main forest classes that could be discriminated with an accuracy of 89% on the basis of lidar data. Lidar can be applied widely for mapping of habitat and assessments of habitat condition (e.g., in support of the European Species and Habitats Directive [92/43/EEC]). However, particular attention needs to be paid to issues of survey design: density of lidar points and geospatial accuracy of ground-truthing and its timing relative to acquisition of lidar data. ©2012 Society for Conservation Biology.

Beginning in 2013, we partnered with the Physics and Astronomy Dept. at Cal Poly Pomona, a Hispanic-serving university, to recruit underserved students. Over 11 years, we have served 155 students. We focus on Astrobiology since the Institute's mission is to explore, understand and explain the origin, nature and prevalence of life in the universe. Our REU students work with mentors at the Institute - a non-profit organization located in California's Silicon Valley-and at the nearby NASA Ames Research Center. Projects span research on survival of microbes under extreme conditions, planetary geology, astronomy, the Search for Extraterrestrial Intelligence (SETI), extrasolar planets and more. The REU program begins with an introductory lectures by Institute scientists covering the diverse astrobiology subfields. A week-long field trip to the SETI Institute's Allen Telescope Array (Hat Creek Radio Astronomy Observatory in Northern California) and field experiences at hydrothermal systems at nearby Lassen Volcanic National Park immerses students in radio astronomy and SETI, and extremophile environments that are research sites for astrobiologists. Field trips expose students to diverse environments and allow them to investigate planetary analogs as our scientists do. Students also participate in local trips to the California Academy of Sciences and other nearby locations of scientific interest, and attend the weekly scientific colloquium hosted by the SETI Institute at Microsoft, other seminars and lectures at SETI Institute and NASA Ames. The students meet and present at a weekly journal club where they hone their presentation skills, as well as share their research progress. At the end of the summer, the REU interns present their research projects at a session of the Institute's colloquium. As a final project, students prepare a 2-page formal abstract and 15-minute presentation that mirrors the requirements for professional conference presentations. In collaboration with the mentors, successful projects are selected and funded for submission to national scientific conferences during the subsequent academic year. This program is funded by the NSF AST Grant # 1359346.

Molecular and microscopic analyses reveal enormous non-cultivable endophytic bacteria in grapevine field shoots with functional significance. Diverse bacteria enter tissue cultures through surface-sterilized tissues and survive surreptitiously with varying taxonomic realignments. The study was envisaged to assess the extent of endophytic bacterial association with field shoot tissues of grapevine and the likelihood of introduction of such internally colonizing bacteria in vitro adopting molecular techniques targeting the non-cultivable bacterial community. PowerFood ® -kit derived DNA from surface-sterilized field shoot tips of grapevine Flame Seedless was employed in a preliminary bacterial class-specific PCR screening proving positive for major prokaryotic taxa including Archaea. Taxonomic and functional diversity were analyzed through whole metagenome profiling (WMG) which revealed predominantly phylum Actinobacteria, Proteobacteria, and minor shares of Firmicutes, Bacteroidetes, and Deinococcus-Thermus with varying functional roles ascribable to the whole bacterial community. Field shoot tip tissues and callus derived from stem segments were further employed in 16S rRNA V3-V4 amplicon taxonomic profiling. This revealed elevated taxonomic diversity in field shoots over WMG, predominantly Proteobacteria succeeded by Actinobacteria, Firmicutes, Bacteroidetes, and 15 other phyla including several candidate phyla (135 families, 179 genera). Callus stocks also displayed broad bacterial diversity (16 phyla; 96 families; 141 genera) bearing resemblance to field tissues with Proteobacterial dominance but a reduction in its share, enrichment of Actinobacteria and Firmicutes, disappearance of some field-associated phyla and detection of a few additional taxonomic groups over field community. Similar results were documented during 16S V3-V4 amplicon taxonomic profiling on Thompson Seedless field shoot tip and callus tissues. Video microscopy on tissue homogenates corroborated enormous endophytic bacteria. This study elucidates a vast diversity of cultivation-recalcitrant endophytic bacteria prevailing in grapevine field shoots, their in vitro introduction, and unsuspecting sustenance with possible silent participation in tissue culture processes.

The management of diversity for conservation and breeding is of great importance for all plant species and is particularly true in perennial species, such as the coffee Coffea canephora. This species exhibits a large genetic and phenotypic diversity with six different diversity groups. Large field collections are available in the Ivory Coast, Uganda and other Asian, American and African countries but are very expensive and time consuming to establish and maintain in large areas. We propose to improve coffee germplasm management through the construction of genetic core collections derived from a set of 565 accessions that are characterized with 13 microsatellite markers. Core collections of 12, 24 and 48 accessions were defined using two methods aimed to maximize the allelic diversity (Maximization strategy) or genetic distance (Maximum-Length Sub-Tree method). A composite core collection of 77 accessions is proposed for both objectives of an optimal management of diversity and breeding. This core collection presents a gene diversity value of 0.8 and exhibits the totality of the major alleles (i.e., 184) that are present in the initial set. The seven proposed core collections constitute a valuable tool for diversity management and a foundation for breeding programs. The use of these collections for collection management in research centers and breeding perspectives for coffee improvement are discussed.

2012-12-01

In 2012, the School of Earth Sciences (SES) at Stanford University sponsored two summer undergraduate research programs. Here we describe these programs and efforts to build a cohesive research cohort among the programs' diverse participants. The two programs, the Stanford School of Earth Sciences Undergraduate Research (SESUR) Program and Stanford School of Earth Sciences Summer Undergraduate Research in Geoscience and Engineering (SURGE) Program, serve different undergraduate populations and have somewhat different objectives, but both provide students with opportunities to work on strongly mentored yet individualized research projects. In addition to research, enrichment activities co-sponsored by both programs support the development of community within the combined SES summer undergraduate research cohort. Over the course of 6 to 9 months, the SESUR Program engages Stanford undergraduates, primarily rising sophomores and juniors, with opportunities to deeply explore Earth sciences research while learning about diverse areas of inquiry within SES. Now in its eleventh year, the SESUR experience incorporates the breadth of the scientific endeavor: finding an advisor, proposal writing, obtaining funding, conducting research, and presenting results. Goals of the SESUR program include (1) providing a challenging and rewarding research experience for undergraduates who wish to explore the Earth sciences; (2) fostering interdisciplinary study in the Earth sciences among the undergraduate population; and (3) encouraging students to major or minor in the Earth sciences and/or to complete advanced undergraduate research in one of the departments or programs within SES. The SURGE Program, now in its second year, draws high performing students, primarily rising juniors and seniors, from 14 colleges and universities nationwide, including Stanford. Seventy percent of SURGE students are from racial/ethnic backgrounds underrepresented in STEM fields, and approximately one-third are the first in their families to attend college. For eight weeks, SURGE scholars conduct independent research with the guidance of faculty, research group mentors, and program assistants. The primary objectives of the SURGE program are to (1) provide undergraduates with a research experience in SES; (2) prepare undergraduates for the process of applying to graduate school; (3) introduce undergraduates to career opportunities in the geosciences and engineering; and (4) increase diversity in SES graduate programs. Independent research, network building, and intense mentoring culminate in a final oral and poster symposium. SESUR and SURGE scholars jointly participate in enrichment activities including faculty research seminars; career, graduate school, and software training workshops; GRE preparation classes; and geoscience-oriented field trips. Interaction among our students takes place through both research and enrichment activities, creating a critical mass of undergraduate scholars and promoting community development. Pre- and post-program surveys indicate that the overall goals of both programs are being achieved.

Metabolomics is a research field used to acquire comprehensive information on the composition of a metabolite pool to provide a functional screen of the cellular state. Studies of the plant metabolome include the analysis of a wide range of chemical species with very diverse physico-chemical properties, and therefore powerful analytical tools are required for the separation, characterization and quantification of this vast compound diversity present in plant matrices. In this review, challenges in the use of mass spectrometry (MS) as a quantitative tool in plant metabolomics experiments are discussed, and important criteria for the development and validation of MS-based analytical methods provided. This article is part of the themed issue ‘Quantitative mass spectrometry’. PMID:27644967

Toxoplasmosis is a cosmopolitan infection caused by the apicomplexan parasite Toxoplasma gondii. This infectious disease is widely distributed across the world where cats play an important role in its spread. The symptomatology caused by this parasite is diverse but the ocular affectation emerges as the most important clinical phenotype. Therefore, we conducted a systematic review of the current knowledge of ocular toxoplasmosis from the genetic diversity of the pathogen towards the treatment available for this infection. This review represents an update to the scientific community regarding the genetic diversity of the parasite, the genetic factors of the host, the molecular pathogenesis and its association with disease, the available diagnostic tools and the available treatment of patients undergoing ocular toxoplamosis. This review will be an update for the scientific community in order to encourage researchers to deploy cutting-edge investigation across this field.

What triggers the rising of an intraspecific biodiversity hotspot? Hints from the agile frog.

Canestrelli, Daniele; Bisconti, Roberta; Sacco, Florinda; Nascetti, Giuseppe

2014-05-23

Hotspots of genetic diversity are regions of utmost importance for species survival and conservation, and their intimate link with the geographic location of glacial refugia has been well established. Nonetheless, the microevolutionary processes underlying the generation of hotspots in such regions have only recently become a fervent field of research. We investigated the phylogeographic and population genetic structure of the agile frog, Rana dalmatina, within its putative refugium in peninsular Italy. We found this region to harbour far more diversity, phylogeographic structure, and lineages of ancient origin than that by the rest of the species' range in Europe. This pattern appeared to be well explained by climate-driven microevolutionary processes that occurred during both glacial and interglacial epochs. Therefore, the inferred evolutionary history of R. dalmatina in Italy supports a view of glacial refugia as 'factories' rather than as repositories of genetic diversity, with significant implications for conservation strategies for hotspots.

More than words: Using visual graphics for community-based health research.

With increased attention to knowledge translation and community engagement in the applied health research field, many researchers aim to find effective ways of engaging health policy and decision makers and community stakeholders. While visual graphics such as graphs, charts, figures and photographs are common in scientific research dissemination, they are less common as a communication tool in research. In this commentary, I illustrate how and why visual graphics were created and used to facilitate dialogue and communication throughout all phases of a community-based health research study with a rural Indigenous community, advancing community engagement and knowledge utilization of a research study. I suggest that it is essential that researchers consider the use of visual graphics to accurately communicate and translate important health research concepts and content in accessible forms for diverse research stakeholders and target audiences.

2018-02-21

The incorporation of biomolecules into nanomaterials generates functional nanosystems with novel and advanced properties, presenting great potential for applications in various fields. Nucleobases, nucleosides and nucleotides, as building blocks of nucleic acids and biological coenzymes, constitute necessary components of the foundation of life. In recent years, as versatile biomolecules for the construction or regulation of functional nanomaterials, they have stimulated interest in researchers, due to their unique properties such as structural diversity, multiplex binding sites, self-assembly ability, stability, biocompatibility, and chirality. In this review, strategies for the synthesis of nanomaterials and the regulation of their morphologies and functions using nucleobases, nucleosides, and nucleotides as building blocks, templates or modulators are summarized alongside selected applications. The diverse applications range from sensing, bioimaging, and drug delivery to mimicking light-harvesting antenna, the construction of logic gates, and beyond. Furthermore, some perspectives and challenges in this emerging field are proposed. This review is directed toward the broader scientific community interested in biomolecule-based functional nanomaterials.

STEM Education for Girls of Color

NASA Astrophysics Data System (ADS)

Yee, Kam H.

Science, technology, engineering, and math (STEM) fields struggle to increase recruitment and retention of girls of color. The dominant framework in STEM education is the pipeline which assumes girls in general lack motivation and interest to persist in STEM fields. Recent public discourse shifts to address institutionalized discrimination and systemic barriers in STEM culture that filter out underrepresented populations. Informal education or complementary learning STEM programs offer alternative opportunities for students to explore outside of rigid school academic and social systems. Few articles look specifically at STEM complementary learning programs, and even fewer focus on the effects on girls of color. This research is a quantitative study to categorize existing mission statements and training behind organizations that provide STEM programs. The results will provide a better understanding of the relationship between practices of STEM education organizations and the programs they create. Diversity training and inclusive language in mission statements had weak correlations with increased cultural responsiveness in the program offerings. The results suggest organizations must be more intentional and explicit when implementing diversity goals.

Single-cell metabolomics: analytical and biological perspectives.

PubMed

Zenobi, R

2013-12-06

There is currently much interest in broad molecular profiling of single cells; a cell's metabolome-its full complement of small-molecule metabolites-is a direct indicator of phenotypic diversity of single cells and a nearly immediate readout of how cells react to environmental influences. However, the metabolome is very difficult to measure at the single-cell level because of rapid metabolic dynamics, the structural diversity of the molecules, and the inability to amplify or tag small-molecule metabolites. Measurement techniques including mass spectrometry, capillary electrophoresis, and, to a lesser extent, optical spectroscopy and fluorescence detection have led to impressive advances in single-cell metabolomics. Even though none of these methodologies can currently measure the metabolome of a single cell completely, rapidly, and nondestructively, progress has been sufficient such that the field is witnessing a shift from feasibility studies to investigations that yield new biological insight. Particularly interesting fields of application are cancer biology, stem cell research, and monitoring of xenobiotics and drugs in tissue sections at the single-cell level.

Bingham, B. L.; Sulkin, S.

2011-12-01

The road to a career in the ocean sciences can be long and challenging, particularly for students from racial/ethnic groups underrepresented in the field. For the past 21 years, faculty and staff at the Shannon Point Marine Center, Western Washington University have annually administered the NSF-funded Multicultural Initiative in the Marine Sciences: Undergraduate Participation (MIMSUP) program. The goal of MIMSUP is to increase diversity in the ocean sciences by moving students though their undergraduate programs into advanced education and leadership positions in the field. Helping students find positions in REU and other focused research programs is an important step along this path. Primary obstacles for the students include 1) a lack of knowledge about opportunities available to them, 2) a lack of experience preparing quality applications and 3) a lack of confidence in their ability to compete for positions. Focused mentoring, with an emphasis on skills development is important in helping outstanding, though inexperienced, students find and excel in REU programs.

Exercise psychology encompasses the disciplines of psychiatry, clinical and counseling psychology, health promotion, and the movement sciences. This emerging field involves diverse mental health issues, theories, and general information related to physical activity and exercise. Numerous research investigations across the past 20 years have shown both physical and psychological benefits from physical activity and exercise. Exercise psychology offers many opportunities for growth while positively influencing the mental and physical health of individuals, communities, and society. However, the exercise psychology literature has not addressed ethical issues or dilemmas faced by mental health professionals providing exercise psychology services. This initial discussion of ethical issues in exercise psychology is an important step in continuing to move the field forward. Specifically, this article will address the emergence of exercise psychology and current health behaviors and offer an overview of ethics and ethical issues, education/training and professional competency, cultural and ethnic diversity, multiple-role relationships and conflicts of interest, dependency issues, confidentiality and recording keeping, and advertisement and self-promotion.

Evolution of Evaluation and Assessment in Diverse Audiences in the Digital Age

NASA Astrophysics Data System (ADS)

Eriksson, S. C.

2015-12-01

Over the past decades, researchers have learned more about how people think and act and about the social and political aspects of teaching and learning. This understanding has brought changes in researchers' and practitioners' interactions with diverse groups and individuals. This paper addresses evaluation, a process that measures the degree to which learning and project goals are met and factors contributing to or hindering outcomes. Parallels are drawn to learning assessment. The concepts of inclusion, participation, and constructivism (Mertens, 1999; Mertens and Hopson, 2006) now drive best evaluation practices for projects with persons with disabilities (AEA, 2011). This is also true in cases of other people who have been marginalized in STEM fields, e.g. women and underrepresented groups. Inclusion of these stakeholders has important implications for the validity of an evaluation, including the accuracy of results (Jacobson et al, 2012; Gill, 1999; Lee, 1999). The American Indian Higher Education Consortium's framework for indigenous groups incorporates their values and goals into evaluation design and implementation. It is feasible to include participant input in designing the questions and methods of obtaining data, ensuring that issues of access, opportunity, and power (Shuffelbeam, 2001) are taken into consideration. Geoscience projects with u-learning and m-learning provide opportunities to test these theoretical models in innovative programs such as: field work for students with physical disability; underrepresented minority, secondary students using mobile devices in contextualized learning in informal settings; and graduate students using digital maps to enhance traditional field work. This study compares program evaluation methodology of tradition learning with that of programs for diverse groups of students using digital technology.

Preventing a Leak: Two Perspectives on Creating Supportive Environment for Graduate Student Colleagues

NASA Astrophysics Data System (ADS)

Wohl, Ellen; Lininger, Katherine

2017-04-01

Debate continues about whether there exists a leaky pipeline for women in STEM fields within academia, as well as the causes of leaks - points in an individual's career where women are more likely than men to choose a non-academic pathway. Statistics on MS and PhD degrees awarded in STEM fields indicate that one of these leaks occurs during and immediately following graduate school. Here, we present two perspectives, that of a full professor and a graduate student, on how to create an environment in which geosciences graduate students can thrive psychologically and professionally. We recognize the challenges faced by many underrepresented groups, but here we focus specifically on gender diversity from the perspective of white women. From the perspective of a faculty advisor overseeing a research group, the goal is to treat each member of the group as an individual and to develop a mentoring relationship that most effectively fosters that individual's development as a scientist, while maintaining a cohesive, collegial group dynamic. Among the recommended ways to achieve this are: maintaining flexibility in the work schedule, with success evaluated by outcomes; consideration of work-life balance; respect for diverse approaches to problem solving; recognition that individuals can be most productive, satisfied, and engaged when their individual contributions are acknowledged and valued; and respect for different choices for a career path and for changes in those choices during graduate studies. From the perspective of a graduate student, it is important that an advisor demonstrates a clear commitment to treating each member of a research group as a valued individual with differing needs. In addition to the recommendations above for achieving a positive and supportive research group, as a graduate student it is useful to have multiple mentors and role models who have had different career tracks and can provide diverse perspectives and advice. Graduate students can also take it upon themselves to enhance retention of underrepresented groups in STEM through forming local support and networking groups or advocating for better institutional policies (e.g., paid parental leave policies for graduate students). Supporting and encouraging graduate students who undertake activities aimed at increasing diversity in STEM is another way that advisors can create a better working environment for their graduate students. Success for women in STEM fields and their retention over the long term can depend upon the experiences they have in graduate school and whether they believe it is possible to create a career path that works for their individual needs and work-life balance.

Agricultural intensification is a leading cause of global biodiversity loss, which can reduce the provisioning of ecosystem services in managed ecosystems. Organic farming and plant diversification are farm management schemes that may mitigate potential ecological harm by increasing species richness and boosting related ecosystem services to agroecosystems. What remains unclear is the extent to which farm management schemes affect biodiversity components other than species richness, and whether impacts differ across spatial scales and landscape contexts. Using a global metadataset, we quantified the effects of organic farming and plant diversification on abundance, local diversity (communities within fields), and regional diversity (communities across fields) of arthropod pollinators, predators, herbivores, and detritivores. Both organic farming and higher in-field plant diversity enhanced arthropod abundance, particularly for rare taxa. This resulted in increased richness but decreased evenness. While these responses were stronger at local relative to regional scales, richness and abundance increased at both scales, and richness on farms embedded in complex relative to simple landscapes. Overall, both organic farming and in-field plant diversification exerted the strongest effects on pollinators and predators, suggesting these management schemes can facilitate ecosystem service providers without augmenting herbivore (pest) populations. Our results suggest that organic farming and plant diversification promote diverse arthropod metacommunities that may provide temporal and spatial stability of ecosystem service provisioning. Conserving diverse plant and arthropod communities in farming systems therefore requires sustainable practices that operate both within fields and across landscapes. © 2017 John Wiley & Sons Ltd.

Ethical aspects of genome diversity research: genome research into cultural diversity or cultural diversity in genome research?

Ilkilic, Ilhan; Paul, Norbert W

2009-03-01

The goal of the Human Genome Diversity Project (HGDP) was to reconstruct the history of human evolution and the historical and geographical distribution of populations with the help of scientific research. Through this kind of research, the entire spectrum of genetic diversity to be found in the human species was to be explored with the hope of generating a better understanding of the history of humankind. An important part of this genome diversity research consists in taking blood and tissue samples from indigenous populations. For various reasons, it has not been possible to execute this project in the planned scope and form to date. Nevertheless, genomic diversity research addresses complex issues which prove to be highly relevant from the perspective of research ethics, transcultural medical ethics, and cultural philosophy. In the article at hand, we discuss these ethical issues as illustrated by the HGDP. This investigation focuses on the confrontation of culturally diverse images of humans and their cosmologies within the framework of genome diversity research and the ethical questions it raises. We argue that in addition to complex questions pertaining to research ethics such as informed consent and autonomy of probands, genome diversity research also has a cultural-philosophical, meta-ethical, and phenomenological dimension which must be taken into account in ethical discourses. Acknowledging this fact, we attempt to show the limits of current guidelines used in international genome diversity studies, following this up by a formulation of theses designed to facilitate an appropriate inquiry and ethical evaluation of intercultural dimensions of genome research.

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.

The under-representation of African American women in the STEM fields within the academy: A historical profile and current perceptions

NASA Astrophysics Data System (ADS)

Howard, Tenisha Senora

This research project seeks to discover the reasons behind the underrepresentation of African American women (AAW) in higher education, particularly in the Science Technology Engineering and Mathematics fields. Why is there underrepresentation of AAW in the STEM fields? Research evidence has demonstrated that AAW face social disparities such as race, gender, and class in the academy. A lack of adequate mentoring and financial resources to support their research efforts are related to these disparities and present fundamental challenges for them. To conduct the inquiry about the barriers AAW have to overcome to achieve success in STEM disciplines, a qualitative research method was used to "attend to social, historical, and temporal context. The findings of these studies are tentatively applied; that is, they may be applicable in diverse situations based on comparability of other contexts" (Mariano, 1995, p. 464). The researcher collected data by conducting in-depth interviews with five participants, using an open-ended conversational format to facilitate the development of trust, rapport, and maximum elicitation of stories from the participants. The results suggest that AAW overcome barriers to successful STEM careers through their family and social ties, mentoring relationships as well as their religious practices.

This article discusses the experiences of community volunteers' participation in a community-based participatory research project in Tāmaki, a low socio-economic and ethnically diverse suburban community within greater Auckland City, New Zealand. In the Tāmaki Community Action Research project, community volunteers were recruited and trained to conduct random household surveys (RHS) and asset mapping commissioned by community groups and government agencies in that area. The volunteers were involved in planning, coordination and ongoing governance of the project and ∼70 residents and local university students participated at different stages of the 2-year project. Over 600 RHS were completed and the volunteers' experiences were recorded in field notes, informal group discussions, daily team meetings and individual interviews and form the basis of this article. Only their experiences are discussed here, not the survey results which will be presented elsewhere. The project reflected the inherent asset-rich nature of the community via examples of individual volunteer empowerment and collective social/community capacity building. Volunteers increased their interpersonal and organizational skills, their understanding of the complexity of their community's logistics and cultural diversity, and gained an increased sense of community purpose and commitment. There was very strong endorsement of culturally sensitive research practice to recognize cultural differences and to engage productively within their richly ethnically diverse community. Full community volunteer participation in the project's governance (i.e. through design, training, implementation and ongoing consultation/management phases) was considered key to sustaining the life of project.

Sport science integration: An evolutionary synthesis.

Balagué, N; Torrents, C; Hristovski, R; Kelso, J A S

2017-02-01

The aim of the paper is to point out one way of integrating the supposedly incommensurate disciplines investigated in sports science. General, common principles can be found among apparently unrelated disciplines when the focus is put on the dynamics of sports-related phenomena. Dynamical systems approaches that have recently changed research in biological and social sciences among others, offer key concepts to create a common pluricontextual language in sport science. This common language, far from being homogenising, offers key synthesis between diverse fields, respecting and enabling the theoretical and experimental pluralism. It forms a softly integrated sports science characterised by a basic dynamic explanatory backbone as well as context-dependent theoretical flexibility. After defining the dynamic integration in living systems, unable to be captured by structural static approaches, we show the commonalities between the diversity of processes existing on different levels and time scales in biological and social entities. We justify our interpretation by drawing on some recent scientific contributions that use the same general principles and concepts, and diverse methods and techniques of data analysis, to study different types of phenomena in diverse disciplines. We show how the introduction of the dynamic framework in sport science has started to blur the boundaries between physiology, biomechanics, psychology, phenomenology and sociology. The advantages and difficulties of sport science integration and its consequences in research are also discussed.

Why is there a need to increase the racial/ethnic diversity of faculty in school psychology? Chiefly, school psychologists serve the most racially/ethnically diverse population: children in US schools. Therefore, developing a knowledge base that is inclusive of this wide range of perspective as well as growing a workforce that is reflective of this diversity is essential to effective service delivery. To achieve this goal, school psychology trainers must develop evidence-based, purposeful efforts to recruit and retain racial/ethnic minority students in doctoral programs. For these reasons, we called for a special issue on diversifying the field of school psychology. The purpose of this special issue is to advance the evidence-base in school psychology on how to increase diverse scholars and leaders in the profession. Moreover, the goal is to also evaluate the status of the profession in effectively recruiting and retaining racial/ethnic minority graduate students, mentoring racial/ethnic minority students to pursue careers in academia, and promoting faculty development and retention of racially and ethnically diverse faculty. Thus, the articles in this special issue will address critical areas where trainers can improve recruitment and retention strategies that will increase the racial/ethnic diversity of school psychology faculty, leaders, and practitioners.

The educational component of the CAREER award "A New Direction into Near-Surface Transport for Weak-Wind Conditions in Plant Canopies" (AGS #0955444) calls for an integration of in-classroom teaching and a new field class to provide students from across the disciplines with an opportunity to explore and learn mechanisms of land-air interactions. The charge is clear, but how do I best do this? This contribution presents a concept of how to address the diverse interests and needs with backgrounds ranging from atmospheric science & engineering to botany & forestry by emphasizing the underlying physical principles of light, heat, and water exchange that are of common interest to many scientific disciplines. The idea behind the teaching technique is to let the students escape from their rather passive role in the classroom by providing opportunities for active participation and discovery through a) developing an online syllabus created by the students for the students, b) offering field excursions to expose students to the research activities funded through this award, c) helping small student teams formulate their own research questions, develop their own experimental design, and collect and evaluate measurements in the field class. In addition to discussing the concept and giving some concrete topical examples, a summary of the student feedback received to date will also be included. However, since the award is just about to enter its second year at the time of writing, a major part of this concept still awaits implementation. Seeking input from other awardees and experienced teachers and educators is therefore intended. A secondary objective of this contribution is to describe the many positive impacts on my career that are evident even after the first year by exposing my research and teaching activities to a much broader audience including the Long-Term Ecological Research community at the HJ Andrews experimental forest in Oregon.

Gender Gap in Science, Technology, Engineering, and Mathematics (STEM): Current Knowledge, Implications for Practice, Policy, and Future Directions

2016-01-01

Although the gender gap in math course-taking and performance has narrowed in recent decades, females continue to be underrepresented in math-intensive fields of Science, Technology, Engineering, and Mathematics (STEM). Career pathways encompass the ability to pursue a career as well as the motivation to employ that ability. Individual differences in cognitive capacity and motivation are also influenced by broader sociocultural factors. After reviewing research from the fields of psychology, sociology, economics, and education over the past 30 years, we summarize six explanations for US women’s underrepresentation in math-intensive STEM fields: (a) cognitive ability, (b) relative cognitive strengths, (c) occupational interests or preferences, (d) lifestyle values or work-family balance preferences, (e) field-specific ability beliefs, and (f) gender-related stereotypes and biases. We then describe the potential biological and sociocultural explanations for observed gender differences on cognitive and motivational factors and demonstrate the developmental period(s) during which each factor becomes most relevant. We then propose evidence-based recommendations for policy and practice to improve STEM diversity and recommendations for future research directions. PMID:28458499

Biodiversity and ecosystem functioning research typically shows positive diversity- productivity relationships. However, local increases in species richness can increase competition within trophic levels, reducing the efficacy of intertrophic level population control. Pseudomonas spp. are a dominant group of soil bacteria that play key roles in plant growth promotion and control of crop fungal pathogens. Here we show that Pseudomonas spp. richness is positively correlated with take-all disease in wheat and with yield losses of ~3 t/ha in the field. We modeled the interactions between Pseudomonas and the take-all pathogen in abstract experimental microcosms, and show that increased bacterial genotypic richness escalates bacterial antagonism and decreases the ability of the bacterial community to inhibit growth of the take-all pathogen. Future work is required to determine the generality of these negative biodiversity effects on different media and directly at infection zones on root surfaces. However, the increase in competition between bacteria at high genotypic richness and the potential loss of fungal biocontrol activity highlights an important mechanism to explain the negative Pseudomonas diversity-wheat yield relationship we observed in the field. Together our results suggest that the effect of biodiversity on ecosystem functioning can depend on both the function and trophic level of interest. PMID:27549739

Malaria, an ancient human infectious disease caused by five species of Plasmodium, among them Plasmodium vivax is the most widespread human malaria species and causes huge morbidity to its host. Identification of genetic marker to resolve higher genetic diversity for an ancient origin organism is a crucial task. We have analyzed genetic diversity of P. vivax field isolates using highly polymorphic antigen gene merozoite surface protein-3 alpha (msp-3 alpha) and assessed its suitability as high-resolution genetic marker for population genetic studies. 27 P. vivax field isolates collected during chloroquine therapeutic efficacy study at Chennai were analyzed for genetic diversity. PCR-RFLP was employed to assess the genetic variations using highly polymorphic antigen gene msp-3 alpha. We observed three distinct PCR alleles at msp-3 alpha, and among them allele A showed significantly high frequency (53%, chi2 = 8.22, p = 0.001). PCR-RFLP analysis revealed 14 and 17 distinct RFLP patterns for Hha1 and Alu1 enzymes respectively. Further, RFLP analysis revealed that allele A at msp-3 alpha is more diverse in the population compared with allele B and C. Combining Hha1 and Alu1 RFLP patterns revealed 21 distinct genotypes among 22 isolates reflects higher diversity resolution power of msp-3 alpha in the field isolates. P. vivax isolates from Chennai region revealed substantial amount of genetic diversity and comparison of allelic diversity with other antigen genes and microsatellites suggesting that msp-3 alpha could be a high-resolution marker for genetic diversity studies among P. vivax field isolates.

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.

Is plant temporal beta diversity of field margins related to changes in management practices?

NASA Astrophysics Data System (ADS)

Alignier, Audrey; Baudry, Jacques

2016-08-01

Field margins have considerable ecological significance in agriculture-dominated landscapes by supporting biodiversity and associated services. However, agricultural changes during mid-20th century led to their drastic loss with a serious threat for biodiversity. Using time-series data, we aimed to get better insights into processes underlying plant patterns of field margins through time by i) quantifying plant temporal beta diversity components, ii) assessing whether the observed changes in plant communities can be related to changes in management practices applied to field margins. During the springs of 1994, 1998 and 2001, we surveyed plant communities and management practices of the same 116 field margins in three contrasted landscapes. We estimated temporal beta diversity in plant communities and partitioned it into its two dissimilarity resultant components, accounting for replacement of species (i.e. turnover) and for the nested gain or loss of species (i.e. nestedness). We then tested whether the observed changes in plant communities between 1994 and 1998 and, between 1998 and 2001 were related to changes in management practices using linear models. Plant communities of field margins exhibited strong temporal beta diversity dominated by turnover. Temporal turnover in plant communities was partly related to changes in management practices, i.e., a decrease of grazing concomitant to an increase of herbicide spraying. However, relationships were not consistent between all landscape contexts nor time period, suggesting that other unmeasured deterministic or stochastic processes could be driving the observed plant patterns. Taken together, our results suggest that maintaining a wide diversity of field margins with contrasted management contribute to maintaining plant diversity at a landscape scale. They underline the value of investigating plant temporal diversity patterns using time-series data and thus, the need to develop long-term studies making it possible to understand ecological processes shaping plant communities in agricultural landscapes.

Progress and Trends in AIE-Based Bioprobes: A Brief Overview.

PubMed

Mei, Ju; Huang, Youhong; Tian, He

2018-04-18

Luminescent bioprobes are powerful analytical means for biosensing and optical imaging. Luminogens featured with aggregation-induced emission (AIE) attributes have emerged as ideal building blocks for high-performance bioprobes. Bioprobes constructed with AIE luminogens have been identified to be a novel class of FL light-up probing tools. In contrast to conventional bioprobes based on the luminophores with aggregation-caused quenching (ACQ) effect, the AIE-based bioprobes enjoy diverse superiorities, such as lower background, higher signal-to-noise ratio and sensitivity, better accuracy, and more outstanding resistance to photobleaching. AIE-based bioprobes have been tailored for a vast variety of purposes ranging from biospecies sensing to bioimaging to theranostics (i.e., image-guided therapies). In this review, recent five years' advances in AIE-based bioprobes are briefly overviewed in a perspective distinct from other reviews, focusing on the most appealing trends and progresses in this flourishing research field. There are altogether 11 trends outlined, which have been classified into four aspects: the probe composition and form (bioconjugtes, nanoprobes), the output signal of probe (far-red/near-infrared luminescence, two/three-photon excited fluorescence, phosphorescence), the modality and functionality of probing system (dual-modality, dual/multifunctionality), the probing object and application outlet (specific organelles, cancer cells, bacteria, real samples). Typical examples of each trend are presented and specifically demonstrated. Some important prospects and challenges are pointed out as well in the hope of intriguing more interests from researchers working in diverse areas into this exciting research field.

Educational challenges of molecular life science: Characteristics and implications for education and research.

Tibell, Lena A E; Rundgren, Carl-Johan

2010-01-01

Molecular life science is one of the fastest-growing fields of scientific and technical innovation, and biotechnology has profound effects on many aspects of daily life-often with deep, ethical dimensions. At the same time, the content is inherently complex, highly abstract, and deeply rooted in diverse disciplines ranging from "pure sciences," such as math, chemistry, and physics, through "applied sciences," such as medicine and agriculture, to subjects that are traditionally within the remit of humanities, notably philosophy and ethics. Together, these features pose diverse, important, and exciting challenges for tomorrow's teachers and educational establishments. With backgrounds in molecular life science research and secondary life science teaching, we (Tibell and Rundgren, respectively) bring different experiences, perspectives, concerns, and awareness of these issues. Taking the nature of the discipline as a starting point, we highlight important facets of molecular life science that are both characteristic of the domain and challenging for learning and education. Of these challenges, we focus most detail on content, reasoning difficulties, and communication issues. We also discuss implications for education research and teaching in the molecular life sciences.

The Rise of Disease Ecology and Its Implications for Parasitology- A Review.

PubMed

Koprivnikar, Janet; Johnson, Pieter T J

2016-08-01

:  Many fields in the biological sciences have witnessed a shift away from organism- or taxon-focused research and teaching in favor of more conceptual and process-driven paradigms. The field of parasitology is no exception, despite the diversity of topics and taxa it encompasses. Concurrently, however, interest in disease ecology has increased dramatically, suggesting new opportunities that merit exploration, as well as the need for parasitology to promote its long history of ecological research to do so. Here we undertake a quantitative analysis of metrics relating to publications, research funding, career opportunities, and undergraduate teaching to comprehensively illustrate the rising prominence of disease ecology. While we distinguish generally between the fields of parasitology and disease ecology, we also emphasize the common interests and complementary approaches that enhanced integration could offer. To illustrate why enhanced integration between these 2 fields is increasingly critical, we highlight 2 successful areas in which parasitology and disease ecology have intersected (community assembly and scale, and the effects of natural enemies on life history traits). We conclude by identifying "frontier topics" that will benefit from greater cooperation and interaction between these currently relatively separate areas and the need for principal investigators to identify and communicate changes in their discipline to students and trainees, which will collectively result in many possible new benefits and prospects for current and future researchers.

Network as transconcept: elements for a conceptual demarcation in the field of public health

2016-01-01

ABSTRACT The main proposal to set up an articulated mode of operation of health services has been the concept of network, which has been appropriated in different ways in the field of public health, as it is used in other disciplinary fields or even taking it from common sense. Amid the diversity of uses and concepts, we recognize the need for rigorous conceptual demarcation about networks in the field of health. Such concern aims to preserve the strategic potential of this concept in the research and planning in the field, overcoming uncertainties and distortions still observed in its discourse-analytic circulation in public health. To this end, we will introduce the current uses of network in different disciplinary fields, emphasizing dialogues with the field of public health. With this, we intend to stimulate discussions about the development of empirical dimensions and analytical models that may allow us to understand the processes produced within and around health networks.

A major national priority is establishing an effective infrastructure for translation of scientific discoveries into the community. Knowledge and practice continue to accelerate in health research yet healthcare recommendation adoption remains slow for practitioners, patients, and communities. Two areas of research placed in the later stages of the translational research spectrum, Community Engagement in Research and Comparative Effectiveness Research, are ideal for approaching this challenge collaboratively. The Clinical and Translational Science Institute of Southeastern Wisconsin convened academics and community-based organizations familiar with these fields of research in a 1-day workshop to establish an initial dialogue on similarities and differences with a goal of exploring ways to operationalize a collective effort. Participants represented four academic institutions and twelve other healthcare and community-based service organizations. Primary fields of study included community engaged research, comparative effectiveness research, psychology, clinical research, administration, nursing, public health, education, and other professionals. This initial report outlines the results of this diverse discussion and provides insights into the priorities, diverging issues, and areas for future examination and practice. Key discoveries reveal clear crosscutting issues, value in philosophical and provocative discussions among investigators, a need for practice and lessons learned, and bidirectional exchange with community representation. © 2014 Wiley Periodicals, Inc.

Graduate students in the astronomy department at the University of Washington began the Pre-Major in Astronomy Program (Pre-MAP) after recognizing that underrepresented students in STEM fields are not well retained after their transition from high school. Pre-MAP is a research and mentoring program that begins with a keystone seminar. First year students enroll in the Pre-MAP seminar to learn astronomical research techniques that they apply to research projects conducted in small groups. Students also receive one-on-one mentoring and peer support for the duration of the academic year and beyond. They are incorporated early into the department by attending Astronomy Department events and Pre-MAP field trips. Successful Pre-MAP students have declared astronomy and physics majors, expanded their research projects beyond the fall quarter, presented posters at the UW Undergraduate Research Symposium, and received research fellowships and summer internships. In this talk, we will discuss how we identified the issues that Pre-MAP was designed to address, what we've learned after six years of Pre-MAP, and share statistical results from a long-term quantitative comparison evaluation.

This article addresses key questions frequently asked by researchers conducting systematic reviews in patient safety. This discipline is relatively young, and asks complex questions about complex aspects of health care delivery and experience, therefore its studies are typically methodologically heterogeneous, non-randomized and complex; but content rich and highly relevant to practice. Systematic reviews are increasingly necessary to drive forward practice and research in this area, but the data do not always lend themselves to 'standard' review methodologies. This accessible 'how-to' article demonstrates that data diversity need not preclude high-quality systematic reviews. It draws together information from published guidelines and experience within our multidisciplinary patient safety research group to provide entry-level advice for the clinician-researcher new to systematic reviewing, to non-biomedical research data or to both. It offers entry-level advice, illustrated with detailed practical examples, on defining a research question, creating a comprehensive search strategy, selecting articles for inclusion, assessing study quality, extracting data, synthesizing data and evaluating the impact of your review. The article concludes with a comment on the vital role of robust systematic reviews in the continuing advancement of the patient safety field. © 2010 Blackwell Publishing Ltd.

Deltaic processes are governed by factors including the characteristics of inflowing sediment (e.g., temporal variability of the load and size class distribution), receiving basins (e.g., water depth, tidal range, circulation pattern, and wind field), and substrate (e.g., sediment type and soil strength). These factors influence the deltaic growth as well as the size and pattern of channel bifurcations. This topic is of importance to deltas experiencing land loss due to subsidence and sea level rise. The Mississippi River Delta is an example where a number of sediment diversions are being considered in conjunction with other restoration actions to minimize loss of wetlands. Historically, the Mississippi River played a significant role in providing sediment, nutrients, and fresh water to support Louisiana's coastal wetland system. As such, a systems perspective for regional-scale implementation of diversions is important. Field observations coupled with numerical modeling at various temporal and spatial scales, has provided insights toward a system-scale approach to design, evaluate and operate sediment diversions. These research activities investigate the uncertainties associated with morphodynamic processes both on the river and receiving basin sides and identify parameters influencing the magnitude and rate of building new land and sustaining existing wetland areas. Specifically, this presentation discusses the impact of extracting sediment and water from fluvial rivers, the ability to convey (and retain) sediment to the receiving basins. In addition to delivering sediment to receiving basins, some proposed sediment diversions could discharge high volumes of nutrient-rich fresh water into existing wetlands and bays. A goal of the analysis presented here is to improve our understanding of morphodynamic responses of the receiving basins and the ecosystem effects of discharges of freshwater and nutrients at this scale.

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.

Molecular targets of alcohol action: translational research for pharmacotherapy development and screening

Summary Alcohol abuse and dependence are multifaceted disorders with neurobiological, psychological, and environmental components. Research on other complex neuropsychiatric diseases suggests that genetically influenced intermediate characteristics affect the risk for heavy alcohol consumption and its consequences. Diverse therapeutic interventions can be developed through identification of reliable biomarkers for this disorder and new pharmacological targets for its treatment. Advances in the fields of genomics and proteomics offer a number of possible targets for the development of new therapeutic approaches. This brain-focused review highlights studies identifying neurobiological systems associated with these targets and possible pharmacotherapies, summarizing evidence from clinically relevant animal and human studies, as well as sketching improvements and challenges facing the fields of proteomics and genomics. Concluding thoughts on using results from these profiling technologies for medication development are also presented. PMID:21199775

The geosciences, like many other scientific disciplines, have struggled to diversify the workforce in the face of frightening demographic trends demonstrating that the needs for skilled researchers will not be met by continuing to attract predominantly Caucasians or by retaining predominantly Caucasian males. A geoscience workforce that fails to represent the racial and gender mix of the population at large runs a greater risk of perpetuating the misperception that science is only for the specially anointed, that the results of research are not relevant to the lives of ordinary people, and that scientific problems very relevant to those citizens are not prioritized. Given how much is at stake, it is critical that we evaluate the effectiveness of efforts to diversity the workforce and invest in programs proven to work. Special care should be taken in determining criteria for success.

Understanding plant reproductive diversity.

PubMed

Barrett, Spencer C H

2010-01-12

Flowering plants display spectacular floral diversity and a bewildering array of reproductive adaptations that promote mating, particularly outbreeding. A striking feature of this diversity is that related species often differ in pollination and mating systems, and intraspecific variation in sexual traits is not unusual, especially among herbaceous plants. This variation provides opportunities for evolutionary biologists to link micro-evolutionary processes to the macro-evolutionary patterns that are evident within lineages. Here, I provide some personal reflections on recent progress in our understanding of the ecology and evolution of plant reproductive diversity. I begin with a brief historical sketch of the major developments in this field and then focus on three of the most significant evolutionary transitions in the reproductive biology of flowering plants: the pathway from outcrossing to predominant self-fertilization, the origin of separate sexes (females and males) from hermaphroditism and the shift from animal pollination to wind pollination. For each evolutionary transition, I consider what we have discovered and some of the problems that still remain unsolved. I conclude by discussing how new approaches might influence future research in plant reproductive biology.

Improving Broader Impacts through Researcher-Educator Partnerships

Since 1998, the Arctic Research Consortium of the United States (ARCUS) has designed and implemented successful Teacher Research Experience (TRE) programs enabling teachers to work directly with polar scientists in the field and bring their experience back to their classrooms and communities. The PolarTREC TRE model, administered during the International Polar Year (2007-2009), is most effective, exhibiting far-reaching broader impacts when ideas are shared, each partners’ expertise is respected, and both work toward the common goal of delivering high-quality information. Between 2004 and 2009, ARCUS has selected, trained, and supported 77 teachers on polar teacher research experiences. Although a limited number of teachers are able to participate in a field experience, selected teachers have expertise in translating research approaches and results into widely shared learning tools and programs. Between 2007-2009, PolarTREC teachers have constructed nearly 100 classroom lesson plans and activities as a result of their experience. Selected teachers are usually well connected within their schools, communities, and professions, bringing the science to numerous followers during their expedition. Live events with teachers and researchers in the field have attracted over 11,000 participants, primarily K-12 students. The PolarTREC TRE Model includes numerous methods to support outreach activities while teachers and researchers are in the field. These include web-based communications, journals, discussion forums, multimedia, and live events—all easily replicable activities with the potential to affect large numbers of people. In addition, the TRE experience continues to produce broader impacts far into the future of the teacher and researcher’s careers through ongoing communications, presentations at professional conferences, and continued support of each other’s work through activities including classroom visits, joint proposal development, and much more. Preliminary evaluation data from 45 teachers and their researchers indicate overwhelming satisfaction with their participation in PolarTREC. Researchers have expressed that both their research and the scientific process have benefited from the inclusion of a teacher on their team. The need to explain their research and “boil it down to the raw essence” helped the research teams see how their work fits into the bigger world picture, communicate outside their scientific discipline, and present their science effectively to diverse public audiences. Although researcher participation in programs like PolarTREC provides a clear and sometimes “easy” route to fulfilling broader impacts, many of the program activities and best practices are documented and can be applied by scientists to their research activities within any discipline or location. Well-tested practices, lessons learned, and preliminary evaluation results from the administration of PolarTREC will be shared widely so that broader impacts can be fulfilled, scientific research can be improved, and important polar science will be shared with diverse student and public audiences.

2016-01-01

Using field notes collected from participant observation of Australian police officers training to work with the transgender community, the current research builds on previous work examining social identity theory (Tajfel, 2010) to explain how one training program implemented to educate police about transgender people challenges police culture. This research determines that police culture, training procedures, and stereotypes of gender are equally influential on police perceptions of all transgender people. Overall, the results indicate that negative police perceptions toward police training reforms strengthen in-group identity of police, and negative out-group perceptions of transgender people.

Acanthamoeba polyphaga mimivirus and other giant viruses: an open field to outstanding discoveries

PubMed Central

2014-01-01

In 2003, Acanthamoeba polyphaga mimivirus (APMV) was first described and began to impact researchers around the world, due to its structural and genetic complexity. This virus founded the family Mimiviridae. In recent years, several new giant viruses have been isolated from different environments and specimens. Giant virus research is in its initial phase and information that may arise in the coming years may change current conceptions of life, diversity and evolution. Thus, this review aims to condense the studies conducted so far about the features and peculiarities of APMV, from its discovery to its clinical relevance. PMID:24976356

Research in the field of primary care has dramatically increased in France in recent years, especially since 2013 with the introduction of primary care as a thematic priority for research proposals launched by the Ministry of Health (Direction générale de l'offre de soins). The RECaP (Research in Clinical Epidemiology and Public Health) network is a French research network supported by Inserm, which recently implemented a specific working group focusing on research in primary care, based on a multidisciplinary approach. Researchers from different specialties participate in this group. The first aim of the group was to reach a common definition of the perimeter and of the panel of healthcare professionals and structures potentially involved in the field of primary care. For this purpose, a selection of different data sets of sources defining primary care was analyzed by the group, each participant collecting a set of sources, from which a synthesis was made and discussed. A definition of primary care at different levels (international, European and French) was summarized. A special attention was given to the French context in order to adapt the perimeter to the characteristics of the French healthcare system, notably by illustrating the different key elements of the definition with the inclusion of primary care actors and the type of practice premises. In conclusion, this work illustrates the diversity of primary care in France and the potential offered for research purposes. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Bacteriophages are ubiquitous and numerous parasites of bacteria and play a critical evolutionary role in virtually every ecosystem, yet our understanding of the extent of the diversity and role of phages remains inadequate for many ecological niches, particularly in cases in which the host is unculturable. During the past 15 years, the emergence of the field of viral metagenomics has drastically enhanced our ability to analyse the so-called viral ‘dark matter’ of the biosphere. Here, we review the evolution of viral metagenomic methodologies, as well as providing an overview of some of the most significant applications and findings in this field of research. PMID:28538703

Since its inception, Bacterial Locomotion and Signal Transduction (BLAST) meetings have been the place to exchange and share the latest developments in the field of bacterial signal transduction and motility. At the 12th BLAST meeting, held last January in Tucson, AZ, researchers from all over the world met to report and discuss progress in diverse aspects of the field. The majority of these advances, however, came at the level of atomic level structures and their associated mechanisms. This was especially true of the biological machines that sense and respond to environmental changes. © 2013 John Wiley & Sons Ltd.

My overall sense of the cyber defense field is one of an adolescent discipline currently bogged down in a cloud of issues, the most iconic of which is the great diversity of approaches that are being aggregated to form a coherent field. Because my own expertise is complex systems and materials physics research, I have limited direct experience in cyber security sciences except as a user of secure networks and computing resources. However, in producing this report, I have found with certainty that there exists no calculus for cyber risk assessment, mitigation, and response, although some hopeful precepts toward thismore » end are emerging.« less

Target 19, set by the Convention on Biological Diversity, seeks to improve the knowledge, science base, and technologies relating to biodiversity. We will fail to achieve this target unless prolific biases in the field of conservation science are addressed. We reveal that comparatively less research is undertaken in the world's most biodiverse countries, the science conducted in these countries is often not led by researchers based in-country, and these scientists are also underrepresented in important international fora. Mitigating these biases requires wide-ranging solutions: reforming open access publishing policies, enhancing science communication strategies, changing author attribution practices, improving representation in international processes, and strengthening infrastructure and human capacity for research in countries where it is most needed.

We are in a new epoch, the Anthropocene, and research into our closest living relatives, the great apes, must keep pace with the rate that our species is driving change. While a goal of many studies is to understand how great apes behave in natural contexts, the impact of human activities must increasingly be taken into account. This is both a challenge and an opportunity, which can importantly inform research in three diverse fields: cognition, human evolution, and conservation. No long-term great ape research site is wholly unaffected by human influence, but research at those that are especially affected by human activity is particularly important for ensuring that our great ape kin survive the Anthropocene.

2010-01-01

In this review, we summarize and critically evaluate the major empirical, conceptual, and theoretical directions that studies of aging families have taken during the first decade of the 21st century. The field has benefited from an expanded perspective based on four overarching themes: (a) complexity in emotional relations, (b) diversity in family structures and households, (c) interdependence of family roles and functions, and (d) patterns and outcomes of caregiving. Although research on aging families has advanced theory and applied innovative statistical techniques, the literature has fallen short in fully representing diverse populations and in applying the broadest set of methodological tools available. We discuss these and other frontier areas of scholarship in light of the aging of baby boomers and their families. PMID:22930600

Process, pattern and scale: hydrogeomorphology and plant diversity in forested wetlands across multiple spatial scales

NASA Astrophysics Data System (ADS)

Alexander, L.; Hupp, C. R.; Forman, R. T.

2002-12-01

Many geodisturbances occur across large spatial scales, spanning entire landscapes and creating ecological phenomena in their wake. Ecological study at large scales poses special problems: (1) large-scale studies require large-scale resources, and (2) sampling is not always feasible at the appropriate scale, and researchers rely on data collected at smaller scales to interpret patterns across broad regions. A criticism of landscape ecology is that findings at small spatial scales are "scaled up" and applied indiscriminately across larger spatial scales. In this research, landscape scaling is addressed through process-pattern relationships between hydrogeomorphic processes and patterns of plant diversity in forested wetlands. The research addresses: (1) whether patterns and relationships between hydrogeomorphic, vegetation, and spatial variables can transcend scale; and (2) whether data collected at small spatial scales can be used to describe patterns and relationships across larger spatial scales. Field measurements of hydrologic, geomorphic, spatial, and vegetation data were collected or calculated for 15- 1-ha sites on forested floodplains of six (6) Chesapeake Bay Coastal Plain streams over a total area of about 20,000 km2. Hydroperiod (day/yr), floodplain surface elevation range (m), discharge (m3/s), stream power (kg-m/s2), sediment deposition (mm/yr), relative position downstream and other variables were used in multivariate analyses to explain differences in species richness, tree diversity (Shannon-Wiener Diversity Index H'), and plant community composition at four spatial scales. Data collected at the plot (400-m2) and site- (c. 1-ha) scales are applied to and tested at the river watershed and regional spatial scales. Results indicate that plant species richness and tree diversity (Shannon-Wiener diversity index H') can be described by hydrogeomorphic conditions at all scales, but are best described at the site scale. Data collected at plot and site scales are tested for spatial heterogeneity across the Chesapeake Bay Coastal Plain using a geostatistical variogram, and multiple regression analysis is used to relate plant diversity, spatial, and hydrogeomorphic variables across Coastal Plain regions and hydrologic regimes. Results indicate that relationships between hydrogeomorphic processes and patterns of plant diversity at finer scales can proxy relationships at coarser scales in some, not all, cases. Findings also suggest that data collected at small scales can be used to describe trends across broader scales under limited conditions.

Fostering Under-represented Minority Student Success and Interest in the Geosciences: Outcomes of the UNC-Chapel Hill Increasing Diversity and Enhancing Academia (IDEA) Program

Hughes, M. H.; Gray, K.; Drostin, M.

2016-12-01

For under-represented minority (URM) students, opportunities to meaningfully participate in academic communities and develop supportive relationships with faculty and peers influence persistence in STEM majors (Figueroa, Hurtado, & Wilkins, 2015; PCAST, 2012; Tsui, 2007). Creating such opportunities is even more important in the geosciences, where a lower percentage of post-secondary degrees are awarded to URM students than in other STEM fields (NSF, 2015; O'Connell & Holmes, 2011; NSF, 2011). Since 2011, Increasing Diversity and Enhancing Academia (IDEA), a program of the UNC-Chapel Hill Institute for the Environment (UNC-IE), has provided 39 undergraduates (predominantly URM and female students) with career-relevant research experiences and professional development opportunities, including a culminating experience of presenting their research at a campus-wide research symposium. External evaluation data have helped to characterize the effectiveness of the IDEA program. These data included pre- and post-surveys assessing students' interest in geosciences, knowledge of career pathways, and perceptions of their abilities related to a specific set of scientific research skills. Additionally, progress towards degrees and dissemination outcomes were tracked. In this presentation, we will share quantitative and qualitative data that demonstrate that participation in the IDEA program has influenced students' interest and persistence in geosciences research and careers. These data range from self-reported competencies in a variety of scientific skills (such as organizing and interpreting data and reading and interpreting science literature) to documentation of student participation in geoscience study and professions. About 69% of participants continued research begun during their internships beyond the internship; and about 38% pursued graduate degrees and secured jobs in geoscience and other STEM fields. (Nearly half are still in school.) Overall, these evaluation data have shown that the IDEA research experience, combined with program elements focused on professional development, reinforces students' sense of their science abilities, connects them to a network of supportive students and professionals and contributes to their sense of belonging within the geosciences.

Engaging diverse community college students in the geosciences through a year-round career mentoring and research workforce program

2017-12-01

Student attrition from STEM majors most often occurs in the first or second year of college. To retain underrepresented minority students who are largely enrolled in community colleges in STEM pathways, it is critical to provide hands-on experiences and exposure to STEM occupations in a supportive community, before the students transfer to four-year colleges. The goal of the Bridge to the Geosciences is to provide community college students with year-round career mentoring, exposure to different fields and organizations in the geosciences through small field or research experiences, and community-building within the cohort and in connection with a broader community of scientists. Each year, 20 students from Citrus College in Glendora, California participate in research "geomodules" organized around the planetary, atmospheric, ocean, and environmental science subfields of the geosciences at: (1) the Oak Crest Institute of Science, a chemistry research and diversity-oriented education organization in Monrovia, CA; (2) the NASA Jet Propulsion Laboratory (JPL), a NASA center in Pasadena, CA; (3) the University of Southern California's (USC) Wrigley Institute for Environmental Studies, a research center on Catalina Island; and (4) the University Corporation for Atmospheric Research (UCAR) in Boulder, CO. A peak experience of the program is a ten-day mini-internship at UCAR in Colorado where the students are immersed in atmospheric research, training, fieldwork, and presenting at a premier facility. Professional development, mentoring, science communication and cohort-development are woven across all four geomodules and throughout the year. This program is funded by the National Science Foundation's Improving Undergraduate STEM Education or IUSE program. Preliminary results indicate that the students' interest in the geosciences, confidence in their skills and identify as a scientist, and their sense of belonging to a cohort are increased by participation in this program.

Gendered negotiations for research participation in community-based studies: implications for health research policy and practice

Kamuya, Dorcas M; Molyneux, Catherine, S; Theobald, Sally

2017-01-01

There is a growing literature documenting the complex realities of consent processes in the field, and the negotiations and ethical dilemmas involved. Much has also been written about how gender and power shape household decision-making processes. However, these bodies of literature have rarely been brought together to inform research theory and practice in low-income settings. In this paper, qualitative research (observation, focus group discussions and interviews) were used alongside large clinical community-based studies conducted on the Kenyan Coast to explore how gender and power relations within households and communities and between fieldworkers and communities shape consent processes and interactions. This exploration is embedded in relevant literature and the implications for community-based health research policy and practice are considered. Across diverse forms of households, we observed significant consultation on whether or not to participate in research. Although men are typically described as household decision-makers, in practice, decision-making processes are often far more nuanced, with many women using their agency to control, sometimes subtly, the decisions made. Where decisions are made without adequately consulting women, many find strategies to exercise their choice, in ways that safeguard important relationships within households in the longer term. We also found that the gender of field staff who typically conduct research activities in the field, including consent processes, can influence household dynamics and decision-making processes with important implications for the science and ethics of research. It is essential that frontline field staff and their supervisors are aware of the complex and gendered realities of consent processes at household level, and their implications, and that they develop appropriate context-informed approaches that support ethical practice.

PREFACE: 15th International Conference on Photoacoustic and Photothermal Phenomena (ICPPP15)

Glorieux, Christ; Thoen, Jan

2010-01-01

Conference banner Although the roots of this scientific field go back to the end of the nineteenth century when A G Bell discovered the photoacoustic effect generated by the absorption of modulated light in a sample, major and rapid progress only occurred since the mid-1970's when the photoacoustic effect in condensed matter was put on a firm theoretical basis by A Rosencwaig and A Gersho. Since that time the fields of photoacoustics and the related fields of photothermal phenomena and laser ultrasonics have grown enormously. A multitude of ways of generating the effects has emerged using all kinds of radiation. Likewise, the diversity in methods for the detection of the generated thermal and acoustic waves has increased dramatically. One of the reasons for the popularity of the photoacoustic and photothermal field is the wide applicability of these techniques for fundamental and applied research. At this moment, the field has become really multidisciplinary and it is safe to say that it has reached a mature state with an established position in measurement technology and materials characterization. This conference as well as the ones before reflected this large diversity in the program topics and the research disciplines of the participants. This 15th International Conference on Photoacoustic and Photothermal Phenomena was held on a campus of the Catholic University of Leuven in Belgium in the week of 19-23 July 2009. During the conference 15 tutorial lectures, 8 plenary lectures, 36 invited talks, 120 oral and 172 poster communications were presented. The conference was attended by 252 participants from 38 countries from all over the world. During a special session award lectures were presented by winners of the prizes of the International Photoacoustic and Photothermal Association (IPPA). Winners of the senior prize were A Mandelis, D Fournier and A C Boccara. The winner of the junior prize was T W Murray. The editors of the proceedings of this conference believe that the published papers provide significant contributions to the field of photoacoustic and phothermal phenomena and can serve as a good introduction to scientists outside of the field.

The urgent environmental issues of today require science-literate adults to engage in business and political decisions to create solutions. Despite the need, few adults have the knowledge and skills of science literacy. This doctoral dissertation is an analytical case study examining the science-learner identity development of Exploratorium Field Trip Explainers. Located in San Francisco, CA, the Exploratorium is a museum of science, art, and human perception dedicated to nurturing curiosity and exploration. Data collected included semi-structured interviews with sixteen former Field Trip Explainers, participant observation of the current Field Trip Explainer Program, and review of relevant documentation. Data analysis employed constant comparative analysis, guided by the communities of practice theoretical framework (Wenger, 1998) and the National Research Council's (2009) Six Strands of Science Learning. Findings of this research indicate that Exploratorium Field Trip Explainers participate in a community of practice made up of a diverse group of people that values curiosity and openness to multiple ways of learning. Many participants entered the Field Trip Explainer Program with an understanding of science learning as a rigid process reserved for a select group of people; through participation in the Field Trip Explainer community of practice, participants developed an understanding of science learning as accessible and a part of everyday life. The findings of this case study have implications for research, theory, and practice in informal adult science learning, access of non-dominant groups to science learning, and adult workplace learning in communities of practice.

The research of the past two decades has firmly established that hormones modulate numerous aspects of cognitive function, including memory, attention, decision-making, and sensory processing. That such a wide variety of hormones influence cognition mediated by multiple nonhypothalamic brain regions illustrates the critical importance of hormones to neural and cognitive function. The diversity of hormonal effects on cognition is evident in the collection of reviews and original research articles assembled for this special section. Together, these articles provide an overview of recent research on varied topics in hormones and cognition, address controversial issues in the field, and discuss challenges that must be overcome in future research to gain a better understanding of the mechanisms through which hormones modulate cognitive function.

To describe the development and testing of a module to improve consent administrators' skills when obtaining research consent from culturally and linguistically diverse and low literacy populations. Development and psychometric testing of video module including community vignettes. Following initial content, face, and construct validity testing by experts, a field trial was conducted with pre- and postknowledge tests and satisfaction surveys completed by 112 consent administrators. Mean score out of a possible 10 on pretest was 8.6 (±standard deviation [SD], 1.55) and on posttest was 9.1 (±SD, 1.2; paired t-test 95% confidence interval of difference: -0.18 to -0.88; two-tailed p = 0.003). The average years of experience with obtaining consent was 6.42 years (range: 0-35), but years of experience was not significantly associated with either pre- or posttest scores (p = 0.82 and 0.44, respectively). Most user evaluations were positive, although suggestions for improvements were made. Although pretest scores were relatively high, training needs of research consent administrators for consenting diverse and low literacy populations may be unmet. We urge that institutional review boards, researchers, policymakers, educators, and bioethicists address the training needs of research consent administrators and we offer this training module as one potential resource and adjunct to such training. © 2015 Wiley Periodicals, Inc.
